Adults with cancer experienced significant reductions in pain after taking medicinal cannabis, in a study.

Physician-prescribed cannabis, particularly cannabinoids, has been shown to ease cancer-related pain in adult cancer patients, who often find inadequate pain relief from medications including opioids, Saro Aprikian, MSc, a medical student at the Royal College of Surgeons, Dublin, and colleagues, wrote in their paper.

However, real-world data on the safety and effectiveness of cannabis in the cancer population and the impact on use of other medications are lacking, the researchers said.

In the study, published in BMJ Supportive & Palliative Care, the researchers reviewed data from 358 adults with cancer who were part of a multicenter cannabis registry in Canada between May 2015 and October 2018.

The average age of the patients was 57.6 years, and 48% were men. The top three cancer diagnoses in the study population were genitorurinary, breast, and colorectal.

Pain was the most common reason for obtaining a medical cannabis prescription, cited by 72.4% of patients.

Data were collected at follow-up visits conducted every 3 months over 1 year. Pain was assessed via the Brief Pain Inventory (BPI) and revised Edmonton Symptom Assessment System (ESAS-r) questionnaires and compared to baseline values. Patients rated their pain intensity on a sliding scale of 0 (none) to 10 (worst possible). Pain relief was rated on a scale of 0% (none) to 100% (complete).

Compared to baseline scores, patients showed significant decreases at 3, 6 and 9 months for BPI worst pain (5.5 at baseline, 3.6 for 3, 6, and 9 months) average pain (4.1 at baseline, 2.4, 2.3, and 2.7 for 3, 6, and 9 months, respectively), overall pain severity (2.7 at baseline, 2.3, 2.3, and 2.4 at 3, 6, and 9 months, respectively), and pain interference with daily life (4.3 at baseline, 2.4, 2.2, and 2.4 at 3, 6, and 9 months, respectively; P less than .01 for all four pain measures).

“Pain severity as reported in the ESAS-r decreased significantly at 3-month, 6-month and 9-month follow-ups,” the researchers noted.

In addition, total medication burden based on the medication quantification scale (MQS) and morphine equivalent daily dose (MEDD) were recorded at 3, 6, 9, and 12 months. MQS scores decreased compared to baseline at 3, 6, 9, and 12 months in 10%, 23.5%, 26.2%, and 31.6% of patients, respectively. Also compared with baseline, 11.1%, 31.3%, and 14.3% of patients reported decreases in MEDD scores at 3, 6, and 9 months, respectively.

Overall, products with equal amounts of active ingredients tetrahydrocannabinol (THC) and cannabidiol (CBD) were more effective than were those with a predominance of either THC or CBD, the researchers wrote.

Medical cannabis was well-tolerated; a total of 15 moderate to severe side effects were reported by 11 patients, 13 of which were minor. The most common side effects were sleepiness and fatigue, and five patients discontinued their medical cannabis because of side effects. The two serious side effects reported during the study period – pneumonia and a cardiovascular event – were deemed unlikely related to the patients’ medicinal cannabis use.

The findings were limited by several factors, including the observational design, which prevented conclusions about causality, the researchers noted. Other limitations included the loss of many patients to follow-up and incomplete data on other prescription medications in many cases.

The results support the use of medical cannabis by cancer patients as an adjunct pain relief strategy and a way to potentially reduce the use of other medications such as opioids, the authors concluded.

The study was supported by the Canadian Consortium for the Investigation of Cannabinoids, Collège des Médecins du Québec, and the Canopy Growth Corporation. The researchers had no financial conflicts to disclose.

Carolina Reyes, a Harvard-trained physician who specializes in high-risk pregnancies, got into medicine to help women obtain health care, especially underserved or marginalized people who face systemic racism. She’s seen progress, albeit slow, over three decades, yet the number of maternal deaths each year continues to rise.

Luckily, she’s got the ear of President Joe Biden’s health secretary.

Dr. Reyes, 64, is married to Health and Human Services Secretary Xavier Becerra, who is championing the administration’s initiative to require all states to provide Medicaid coverage to mothers for a year after giving birth. In March, the Centers for Disease Control and Prevention released data showing a 40% increase in U.S. maternal deaths from 2020 to 2021. The mortality rate among Black women was 2.6 times that of white women, no matter their economic status.

Over the years, Mr. Becerra has spoken highly of his wife’s expertise, but she downplays her influence, saying her husband of nearly 35 years “had it in him to begin with” to improve health care for women and to demand fewer pregnancy-related deaths. She, too, describes the nation’s high maternal mortality rate as unacceptable and preventable.

Dr. Reyes, a Latina who grew up as one of eight children in California’s agricultural heartland, now practices perinatology at the University of California, Davis. She is a member of a California Department of Public Health panel that reviews cases of maternal deaths and recommends improvements. And she chairs the board of the California Health Care Foundation, a nonprofit that works to increase health care access. (California Healthline is an editorially independent service of the California Health Care Foundation.)

Her work has been a blend of medicine and advocacy, and she worries recent federal court rulings will erode hard-fought victories regarding the safety of pregnant women and their babies. She discussed the nation’s maternal health crisis and health care disparities in an interview, which has been edited for length and clarity.
 

Question: When did you first realize there are disparities in the health care system?

Answer: When I was in high school in the Fresno Unified School District, we were under a consent decree to desegregate. And I was, at the time, student body president at Roosevelt High School. I was asked to be on this unified school district desegregation task force, where the district had to come up with a plan.

It was a time when I really had incredible exposure to how policies are made at a larger level, societal level, that really determine where people live, where they can seek health care, where they go to school. That experience had a tremendous impact on my life in terms of what I wanted to do in a career and how to give back.
 

Q: The U.S. has one of the best health care systems in the world, yet the maternal mortality rate is high compared with other developed countries. Why do think that is?

A. What we know by the CDC and maternal mortality review committees is that about 60% of maternal deaths are considered preventable. And that’s really been a lot of what I’ve tried to focus on: What can we do to reduce the severity of disease? Or what can we do within the role that we play in maternal health that can reduce that?

We know that there are societal issues absolutely that increase women’s risks and there are public health issues. But there’s a role that hospitals play in helping reduce that risk. Ten years ago, I was on the maternal mortality review committee for the state of California when we started reviewing cases of women who died within hospital systems to see, “Is there a role that we can play in a hospital system to reduce that risk?”

We recognized that sometimes there were conditions that were not recognized early enough so that there was a delay in the care. Sometimes there was a misdiagnosis. Or in some hospital systems, especially rural systems where there aren’t as many resources, sometimes there was the lack of specialists available. So, we’ve identified these risks and said, “We can do something about them.”
 

Q: You served on a federal panel 20 years ago that published a groundbreaking report identifying racism in health care. It seems as if we could be much further along.

A. The purpose of that committee was to really answer the question: Do patients receive a different level of care based on race? Looking back, we knew there was something there, but we really didn’t know. And it took months for the committee to come to that agreement, that there was a difference. I mean, that was honestly monumental, because we just didn’t have that level of consensus before. And so just to say “That treatment is unequal and it’s unacceptable” was really profound.

We thought that the 700-page report was going to be a time period where there was going to be tremendous movement, and I think I’ve learned over 20 years that change doesn’t happen quickly, especially when providers and health systems don’t see that they play a role. It’s like … “OK, so maybe it exists, but not for me.”

We all saw George Floyd and how he was treated. And during COVID we saw a tremendous difference in who was dying, right? Underrepresented minorities – certainly much higher. It was that culmination that made us realize the elephant in the room. We can’t ignore that this does exist, that there is a difference in how people are treated, even in our health care system.
 

Q: When addressing racism in health care, you talk about diversifying not just the health care workforce, but also the boardrooms of hospitals and health systems. Why is that important?

A. At the board level, change is hard. But we all play a role because leadership really helps determine much of what’s carried out. So, to have a leadership that is understanding and representative of the communities they serve, I think it has been demonstrated that we do make a difference.

Q: As a health care provider, do you have a wish list of policies you’d like the government to take up?

A. There was tremendous effort around offering preventive health services as a part of what was covered under the Affordable Care Act. And individuals exhaled, finally thinking this is a tremendous win, especially for women in pregnancy. Because we fought for preventive health services to help them have access so they can prepare for their pregnancy. So, for women, this was huge. But now with the Texas federal court ruling that the U.S. Preventive Services Task Force didn’t have any authority, it is a tremendous step backward.

We have culturally, linguistically appropriate standards in place, but it’s a matter in terms of how they’re carried out by state and by individual hospital systems. My wish list is that we really do listen to our patients, speak to them in a language of their choice, and provide them written materials in the language of their choice. We don’t fully do that.
 

Q: You mentioned one Texas ruling on the ACA. What’s your take on the ruling by another Texas judge suspending the abortion pill? And the U.S. Supreme Court’s overturning of Roe v. Wade?A. As a maternal-fetal medicine specialist who tries to help women plan for pregnancies, those rulings are a tremendous setback.

Q: And what about women of color? Will they find access to abortion services more difficult?

A. Oh, absolutely. When we speak of underrepresented minorities or those with less resources, they have less resources to then seek the appropriate care. Some women may have the opportunity to go to a different state or seek care elsewhere if their state doesn’t provide it. Many women just don’t have those resources to devote to them and don’t have a choice. So, we will see that disparity widen.

This article was produced by KFF Health News, which publishes California Healthline, an editorially independent service of the California Health Care Foundation.

Cancer research has made big strides over the past few decades, leading to better prevention efforts, improved treatment options, and longer survival. Despite the significant progress, there is still a lot of work to do. 

In an article published in Cell, cancer specialists from across the globe provided their take on the big questions worth exploring in research over the coming years.

More sex-specific research

Sherene Loi, MBBS, PhD, head of the Translational Breast Cancer Genomics and Therapeutics Laboratory at the MacCallum Cancer Centre in Melbourne, said there needs to be more research on the differences in immune-related adverse events and immune responses between the sexes.

Dr. Loi’s recent research in mouse models has revealed that immune checkpoint inhibitors can lead to reduced oocyte reserves, and if those insights are validated in humans, it could have big implications for women of childbearing age who may face premature menopause and infertility.

“It is astonishing to realize that very little research has been done to investigate the long-term reproductive or fertility consequences of new agents we investigate in the phase 3 setting and then prescribe routinely in the curative setting,” Dr. Loi said. 
 

The global cancer community

C. S. Pramesh, MMBS, MS, FRCS, director of Tata Memorial Hospital in Mumbai, India, said that cancer research should prioritize global experiences, instead of focusing so heavily on high-income countries such as the United States.

“With much of the cancer burden likely to fall on low- and middle-income countries, it seems incongruous that almost 90% of cancer research currently takes place in high-income countries,” Dr. Pramesh said. “Neither the discordance between the cancer burden and research funding in high-income countries nor the types of problems or solutions addressed in these countries are relevant to the majority of patients with cancer in the world.”

Bishal Gyawali, MD, PhD, has discussed a similar need to prioritize cancer care in low- and middle-income countries, what he has dubbed “cancer groundshot.”

Dr. Pramesh described a brainstorming session among colleagues with global cancer expertise in which they identified five broad themes especially relevant to a global community. These themes include reducing the burden of patients presenting with advanced disease as well as improving access, affordability, and outcomes through solution-oriented research – goals that are critical but often not prioritized by high-income countries or industry, he said.

“Now is the time for the global community to wake up, take notice, and change the direction of cancer research for the larger public good,” Dr. Pramesh said.
 

Prioritizing combination therapies

The next big focus in cancer research should be to develop effective combination therapies, according to René Bernards, PhD, of The Netherlands Cancer Institute.

“Resistance to therapy remains a major obstacle in the treatment of cancer,” Dr. Bernards said. But, as the AIDS pandemic has taught us, the use of multiple drugs with “nonoverlapping resistance mechanisms can make a deadly disease with a high mutation rate chronic.”

A growing body of evidence highlights the relevance of this strategy to oncology. A recent study, for instance, highlighted the effectiveness of dual immune checkpoint inhibitors to treat advanced melanoma. 

“I believe that academic researchers can deliver more clinical benefit to patients by focusing on finding highly effective combinations of existing drugs than by searching for more drug targets,” he said. “Over time, this would also contribute to affordable health care through use of more generic drugs.”
 

Cancer drugs and the heart

Cardiologist Javid Moslehi, MD, who specializes in the cardiovascular health of patients with cancer, believes cardio-oncology should be the next frontier. During his research fellowship, Dr. Moslehi discovered that “many novel cancer therapies were leading to cardiovascular adverse effects, both during treatment and survivorship.”

But, Dr. Moslehi explained, “we are entering [uncharted] waters.”

Patients who receive immune checkpoint inhibitors may, for instance, develop fulminant myocarditis. Dr. Moslehi and colleagues have also found in preclinical models that abatacept (CTLA4-Ig) may be an effective treatment for myocarditis.

“Because of the targeted nature of new cancer therapies, cardiovascular sequelae may provide insights into cardiac biology, making cardio-oncology a novel platform for cardiovascular investigation,” Dr. Moslehi explained.
 

Inside rare cancers

William Sellers, MD, director of the Broad Institute of MIT’s Cancer Program, Cambridge, Mass., said rare cancers should be the next focus.

After all, “rare cancers are only rare in isolation,” Dr. Sellers said, noting that these cancers make up 20%-24% of all cancer diagnoses.

Although funding for rare cancer research remains limited, investing more could benefit patients in the long run. In early 2023, Pfizer announced plans to explore more options for early stage treatments for rare diseases and cancers. 

“New initiatives supporting direct-to-patient cohort enrollment bridging geographic fragmentation and rare cancer model development, enabling preclinical research to accelerate, are the first steps along a path toward curing these diseases,” he said. 

The researchers reported numerous relationships with pharmaceutical companies.

Each May, the gastroenterology community gathers for Digestive Disease Week® to be inspired, meet up with friends and colleagues from across the globe, and learn the latest in scientific advances to inform how we care for our patients in the clinic, on inpatient wards, and in our endoscopy suites. DDW® 2023, held in the Windy City of Chicago, does not disappoint. This year’s conference features a dizzying array of offerings, including 3,500 poster and ePoster presentations and 1,300 abstract lectures, as well as the perennially well-attended AGA Post-Graduate Course and other offerings.

This year’s AGA Presidential Plenary, hosted on May 8 by outgoing AGA President Dr. John M. Carethers, is not to be missed. The session will honor the 125-year history of the AGA and recognizes the barriers overcome in diversifying the practice of gastroenterology. You will learn about individuals such as Alexis St. Martin, MD; Basil Hirschowitz, MD, AGAF; Leonidas Berry, MD; Sadye Curry, MD; and, other barrier-breakers in GI who have been instrumental in shaping the modern practice of gastroenterology. I hope you will join me in attending.

In this month’s issue of GIHN, we introduce the winner of the 2023 AGA Shark Tank innovation competition, which was held during the 2023 AGA Tech Summit. We also report on a landmark phase 4, double-blind randomized trial published in the New England Journal of Medicine demonstrating the effectiveness of vedolizumab in inducing remission in chronic pouchitis, and a new AGA clinical practice update on the role of EUS-guided gallbladder drainage in acute cholecystitis.

The AGA Government Affairs Committee also updates us on their advocacy to reform prior authorization policies affecting GI practice, and explains how you can assist in these efforts. In our Member Spotlight, we introduce you to gastroenterologist Sharmila Anandasabapthy, MD, who shares her passion for global health and the one piece of career advice she’s glad she ignored.

Dear friends,

Spring is coming to an end, and in this time with the upcoming summer usually racing by, I always find myself reflecting on the past year. I celebrate my achievements (both personal and work related), try not to be too hard on myself with unaccomplished tasks, and plan goals for the upcoming year. Most importantly, it’s a time to be grateful for both opportunities and challenges. Thank you for your engagement with The New Gastroenterologist, and as you go through this issue, I hope you can find time for some spring reflections as well!

In this issue’s In Focus, Dr. Tanisha Ronnie, Dr. Lauren Bloomberg, and Dr. Mukund Venu break down the approach to a patient with dysphagia, a common and difficult encounter in GI practice. They emphasize the importance of a good clinical history as well as understanding the role of diagnostic testing. In our Short Clinical Review section, Dr. Noa Krugliak Cleveland and Dr. David Rubin review the rising role of intestinal ultrasound in inflammatory bowel disease, how to be trained, and how to incorporate it in clinical practice.

As early-career gastroenterologists, Dr. Samad Soudagar and Dr. Mohammad Bilal were tasked with establishing an advanced endoscopy practice, which may be overwhelming for many. They synthesized their experiences into 10 practical tips to build a successful practice. Our Post-fellowship Pathways article highlights Dr. Katie Hutchins’s journey from private practice to academic medicine; she provides insights into the life-changing decision and what she learned about herself to make that pivot.

In our Finance section, Dr. Kelly Hathorn and Dr. David Creighton reflect on navigating as new parents while both working full time in medicine; their article weighs the pros and cons of various childcare options in the post–COVID pandemic world.

In an additional contribution this issue, gastroenterology and hepatology fellowship program leaders at the University of Florida, Gainesville, describe their experience with virtual recruitment, including feedback from their candidates, especially as we enter another cycle of GI Match.

If you are interested in contributing or have ideas for future TNG topics, please contact me (jtrieu23@gmail.com), or Jillian Schweitzer (jschweitzer@gastro.org), managing editor of TNG.

Until next time, I leave you with a historical fun fact, because we would not be where we are without appreciating where we were: The first formalized gastroenterology fellowship curriculum was a joint publication by four major GI and hepatology societies in 1996 – just 27 years ago!

Sharmila Anandasabapathy, MD, knew she wanted to focus on endoscopy when she first started her career. Her passion would someday translate into a worldwide effort to expand and test this technology.

While leading an endoscopy unit in New York City, Dr. Anandasabapathy began developing endoscopic and imaging technologies for underresourced and underserved areas. These technologies eventually made their way into global clinical trials.

“We’ve gone to clinical trial in over 2,000 patients worldwide. When I made that jump into global GI, I was able to make that jump into global health in general,” said Dr. Anandasabapathy.

Baylor College of Medicine

As vice president for global programs at Baylor College of Medicine in Houston, Dr. Anandasabapathy currently focuses on clinical and translational research.

“We’re looking at the development of new, low-cost devices for early cancer detection in GI globally. I oversee our global programs across the whole college, so it’s GI, it’s surgery, it’s anesthesia, it’s obstetrics, it’s everything.”

In an interview, Dr. Anandasabapathy discussed what attracted her to gastroenterology and why she always takes the time to smile at her patients.
 

Q: Why did you choose GI? 

A: There’s two questions in there: Why I chose GI and why I chose endoscopy.

I chose GI because when I was in my internal medicine training, they seemed like the happiest people in the hospital. They liked what they did. You could make a meaningful impact even at 3 a.m. if you were coming in for a variceal bleed. Everybody seemed happy with their choice of specialty. I was ready to be an oncologist, and I ended up becoming a gastroenterologist.

I chose endoscopy because it was where I wanted to be when I woke up in the morning. I was happy there. I love the procedures; I love the hand-eye coordination. I liked the fact that these were relatively shorter procedures, that it was technology based, and there was infinite growth.
 

Q: Was there a time when you really helped a patient by doing that endoscopy, preventing Barrett’s esophagus or even cancer?

A: I can think of several times where we had early cancers and it was a question between endoscopic treatment or surgery. It was always discussed with the surgeons. We made the decision within a multidisciplinary group and with the patient, but we usually went with the endoscopic options and the patients have done great. We’ve given them a greater quality of life, and I think that’s really rewarding.

Q: What gives you the most joy in your day-to-day practice?

A: My patients. I work with Barrett’s esophagus patients, and they tend to be well informed about the research and the science. I’m lucky to have a patient population that is really interested and willing to participate in that. I also like my students, my junior faculty. I like teaching and the global application of teaching.

Q: What fears did you have to push past to get to where you are in your career?

A: That I would never become an independent researcher and do it alone. I was able to, over time. The ability to transition from being independent to teaching others and making them independent is a wonderful one.

Early on when I was doing GI, I remember looking at my division, and there were about 58 gastroenterologists and only 2 women. I thought at the time, “Well, can I do it? Is this a field that is conducive with being a woman and having a family?” It turned out that it is. Today, I’m really gratified to see that there are more women in GI than there ever were before.
 

Q: Have you ever received advice that you’ve ignored?A: Yes. Early in my training in internal medicine, I was told that I smiled too much and that my personality was such that patients and others would think I was too glib. Medicine was a serious business, and you shouldn’t be smiling. That’s not my personality – I’m not Eeyore. I think it’s served me well to be positive, and it’s served me well with patients to be smiling. Especially when you’re dealing with patients who have precancer or dysplasia and are scared – they want reassurance and they want a level of confidence. I’m glad I ignored that advice.

Q: What would be your advice to medical students?

A: Think about where you want to be when you wake up in the morning. If it’s either in a GI practice or doing GI research or doing endoscopy, then you should absolutely do it.

As vice president for global programs at Baylor College of Medicine in Houston, Dr. Anandasabapathy currently focuses on clinical and translational research.

“We’re looking at the development of new, low-cost devices for early cancer detection in GI globally. I oversee our global programs across the whole college, so it’s GI, it’s surgery, it’s anesthesia, it’s obstetrics, it’s everything.”

In an interview, Dr. Anandasabapathy discussed what attracted her to gastroenterology and why she always takes the time to smile at her patients.
 

Q: Why did you choose GI? 

A: There’s two questions in there: Why I chose GI and why I chose endoscopy.

I chose GI because when I was in my internal medicine training, they seemed like the happiest people in the hospital. They liked what they did. You could make a meaningful impact even at 3 a.m. if you were coming in for a variceal bleed. Everybody seemed happy with their choice of specialty. I was ready to be an oncologist, and I ended up becoming a gastroenterologist.

I chose endoscopy because it was where I wanted to be when I woke up in the morning. I was happy there. I love the procedures; I love the hand-eye coordination. I liked the fact that these were relatively shorter procedures, that it was technology based, and there was infinite growth.
 

Q: Was there a time when you really helped a patient by doing that endoscopy, preventing Barrett’s esophagus or even cancer?

A: I can think of several times where we had early cancers and it was a question between endoscopic treatment or surgery. It was always discussed with the surgeons. We made the decision within a multidisciplinary group and with the patient, but we usually went with the endoscopic options and the patients have done great. We’ve given them a greater quality of life, and I think that’s really rewarding.

Q: What gives you the most joy in your day-to-day practice?

A: My patients. I work with Barrett’s esophagus patients, and they tend to be well informed about the research and the science. I’m lucky to have a patient population that is really interested and willing to participate in that. I also like my students, my junior faculty. I like teaching and the global application of teaching.

Q: What fears did you have to push past to get to where you are in your career?

A: That I would never become an independent researcher and do it alone. I was able to, over time. The ability to transition from being independent to teaching others and making them independent is a wonderful one.

Early on when I was doing GI, I remember looking at my division, and there were about 58 gastroenterologists and only 2 women. I thought at the time, “Well, can I do it? Is this a field that is conducive with being a woman and having a family?” It turned out that it is. Today, I’m really gratified to see that there are more women in GI than there ever were before.
 

Q: Have you ever received advice that you’ve ignored?A: Yes. Early in my training in internal medicine, I was told that I smiled too much and that my personality was such that patients and others would think I was too glib. Medicine was a serious business, and you shouldn’t be smiling. That’s not my personality – I’m not Eeyore. I think it’s served me well to be positive, and it’s served me well with patients to be smiling. Especially when you’re dealing with patients who have precancer or dysplasia and are scared – they want reassurance and they want a level of confidence. I’m glad I ignored that advice.

Q: What would be your advice to medical students?

A: Think about where you want to be when you wake up in the morning. If it’s either in a GI practice or doing GI research or doing endoscopy, then you should absolutely do it.

Sharmila Anandasabapathy, MD, knew she wanted to focus on endoscopy when she first started her career. Her passion would someday translate into a worldwide effort to expand and test this technology.

While leading an endoscopy unit in New York City, Dr. Anandasabapathy began developing endoscopic and imaging technologies for underresourced and underserved areas. These technologies eventually made their way into global clinical trials.

“We’ve gone to clinical trial in over 2,000 patients worldwide. When I made that jump into global GI, I was able to make that jump into global health in general,” said Dr. Anandasabapathy.

Prepare for endometriosis excision surgery with a multidisciplinary approach

Iris Kerin Orbuch, MD

Director, Advanced Gynecologic Laparoscopy Center, Los Angeles and New York City.

Series introduction

Charles Miller, MD

Professor, Obstetrics and Gynecology, Department of Clinical Sciences, Rosalind Franklin University of Medicine and Science, North Chicago, Illinois.
 

As I gained more interest and expertise in the treatment of endometriosis, I became aware of several articles concluding that if a woman sought treatment for chronic pelvic pain with an internist, the diagnosis would be irritable bowel syndrome (IBS); with a urologist, it would be interstitial cystitis; and with a gynecologist, endometriosis. Moreover, there is an increased propensity for IBS and IC in patients with endometriosis. There also is an increased risk of small intestine bacterial overgrowth (SIBO), as noted by our guest author for this latest installment of the Master Class in Gynecologic Surgery, Iris Orbuch, MD.

Like our guest author, I have also noted increased risk of pelvic floor myalgia. Dr. Orbuch clearly outlines why this occurs. In fact, we can now understand why many patients have multiple pelvic pain–inducing issues compounding their pain secondary to endometriosis and leading to remodeling of the central nervous system. Therefore, it certainly makes sense to follow Dr. Orbuch’s recommendation for a multidisciplinary pre- and postsurgical approach “to downregulate the pain generators.”

Dr. Orbuch is a minimally invasive gynecologic surgeon in Los Angeles who specializes in the treatment of patients diagnosed with endometriosis. Dr. Orbuch serves on the Board of Directors of the Foundation of the American Association of Gynecologic Laparoscopists and has served as the chair of the AAGL’s Special Interest Group on Endometriosis and Reproductive Surgery. She is the coauthor of the book “Beating Endo —How to Reclaim Your Life From Endometriosis” (New York: HarperCollins; 2019). The book is written for patients but addresses many issues discussed in this installment of the Master Class in Gynecologic Surgery.

The perils of CA-125 as a diagnostic tool in patients with adnexal masses

Katherine Tucker, MD

Assistant Professor of Gynecologic Oncology at the University of North Carolina at Chapel Hill.
 

CA-125, or cancer antigen 125, is an epitope (antigen) on the transmembrane glycoprotein MUC16, or mucin 16. This protein is expressed on the surface of tissue derived from embryonic coelomic and Müllerian epithelium including the reproductive tract. CA-125 is also expressed in other tissue such as the pleura, lungs, pericardium, intestines, and kidneys. MUC16 plays an important role in tumor proliferation, invasiveness, and cell motility.1 In patients with epithelial ovarian cancer (EOC), CA-125 may be found on the surface of ovarian cancer cells. It is shed in the bloodstream and can be quantified using a serum test.

There are a number of CA-125 assays in commercial use, and although none have been deemed to be clinically superior, there can be some differences between assays. It is important, if possible, to use the same assay when following serial CA-125 values. Most frequently, this will mean getting the test through the same laboratory.

Few women identify breast density as a breast cancer risk

Walter Alexander
 

A qualitative study of breast cancer screening–age women finds that few women identified breast density as a risk factor for breast cancer.

Most women did not feel confident they knew what actions could mitigate breast cancer risk, leading researchers to the conclusion that comprehensive education about breast cancer risks and prevention strategies is needed.

CDC recommends universal hepatitis B screening of adults

Lucy Hicks
 

Adults should be tested for hepatitis B virus (HBV) at least once in their lifetime, according to updated guidelines from the Centers for Disease Control and Prevention.

This is the first update to HBV screening guidelines since 2008, the agency said.

“Risk-based testing alone has not identified most persons living with chronic HBV infection and is considered inefficient for providers to implement,” the authors write in the new guidance, published in the CDC’s Morbidity and Mortality Weekly Report. “Universal screening of adults for HBV infection is cost-effective, compared with risk-based screening and averts liver disease and death. Although a curative treatment is not yet available, early diagnosis and treatment of chronic HBV infections reduces the risk for cirrhosis, liver cancer, nd death.”

An estimated 580,000 to 2.4 million individuals are living with HBV infection in the United States, and two-thirds may be unaware they are infected, the agency said.

The virus spreads through contact with blood, semen, and other body fluids of an infected person.

The guidance now recommends using the triple panel (HBsAg, anti-HBs, total anti-HBc) for initial screening.

“It can help identify persons who have an active HBV infection and could be linked to care; have [a] resolved infection and might be susceptible to reactivation (for example, immunosuppressed persons); are susceptible and need vaccination; or are vaccinated,” the authors write.
 

Ectopic pregnancy risk and levonorgestrel-releasing IUD

Diana Swift
 

Researchers report that use of any levonorgestrel-releasing intrauterine system was associated with a significantly increased risk of ectopic pregnancy, compared with other hormonal contraceptives, in a study published in JAMA.

A national health database analysis headed by Amani Meaidi, MD, PhD, of the Danish Cancer Society Research Center, Cancer Surveillance and Pharmacoepidemiology, in Copenhagen, compared the 13.5-mg with the 19.5-mg and 52-mg dosages of levonorgestrel-releasing intrauterine systems (IUSs).

The hormone content in levonorgestrel-releasing IUSs must be high enough to maintain optimal contraceptive effect but sufficiently low to minimize progestin-related adverse events, Dr. Meaidi and colleagues noted; they advised using the middle dosage of 19.5 mg. All dosages are recommended for contraception, with the highest dosage also recommended for heavy menstrual bleeding.

“If 10,000 women using the hormonal IUD for 1 year were given the 19.5-mg hormonal IUD instead of the 13.5-mg hormonal IUD, around nine ectopic pregnancies would be avoided,” Dr. Meaidi said in an interview.
 

EPA seeks to limit ‘forever’ chemicals in U.S. drinking water

Lisa Nainggolan
 

The Environmental Protection Agency is proposing a new rule that would greatly limit the concentration of endocrine-disrupting “forever” chemicals in drinking water.

The EPA on Tuesday announced the proposed National Primary Drinking Water Regulation (NPDWR) for six polyfluoroalkyl substances, more commonly known as PFAS, which are human-made chemicals used as oil and water repellents and coatings for common products including cookware, carpets, and textiles. Such substances are also widely used in cosmetics and food packaging.

The Endocrine Society, which represents more than 18,000 doctors who treat hormone disorders, says it fully supports the new EPA proposal. It explains that these substances, also known as endocrine-disrupting chemicals, “do not break down when they are released into the environment, and they continue to accumulate over time. They pose health dangers at incredibly low levels and have been linked to endocrine disorders such as cancer, thyroid disruption, and reproductive difficulties.”

Have you ever looked at the operating room (OR) trash bin at the end of a case and wondered if all that waste is necessary? Since I started my residency, not a day goes by that I have not asked myself this question.

In the mid-1990s, John Elkington introduced the concept of the triple bottom line—that is, people, planet, and profit—for implementation and measurement of sustainability in businesses.¹ The health care sector is no exception when it comes to the bottom line! However, “people” remain the priority. What is our role, as ObGyns, in protecting the “planet” while keeping the “people” safe?

According to the World Health Organization (WHO), climate change remains the single biggest health threat to humanity.² The health care system is both the victim and the culprit. Studies suggest that the health care system, second to the food industry, is the biggest contributor to waste production in the United States. This sector generates more than 6,000 metric tons of waste each day and nearly 4 million tons (3.6 million metric tons) of solid waste each year.³ The health care system is responsible for an estimated 8% to 10% of total greenhouse gas emissions in the United States; the US health care system alone contributes to more than one-fourth of the global health care carbon footprint. If it were a country, the US health care system would rank 13th among all countries in emissions.⁴In turn, pollution produced by the health sector negatively impacts population health, further burdening the health care system. According to 2013 study data, the annual health damage caused by health care pollution was comparable to that of the deaths caused by preventable medical error.⁴

Aside from the environmental aspects, hospital waste disposal is expensive; reducing this cost is a potential area of interest for institutions.

As ObGyns, what is our role in reducing our waste generation and carbon footprint while keeping patients safe?

Defining health care waste, and disposal considerations

The WHO defines health care waste as including “the waste generated by health-care establishments, research facilities, and laboratories” as well as waste from scattered sources such as home dialysis and insulin injections.⁵ Despite representing a relatively small physical area of hospitals, labor and delivery units combined with ORs account for approximately 70% of all hospital waste.³ Operating room waste consists of disposable surgical supplies, personal protective equipment, drapes, plastic wrappers, sterile blue wraps, glass, cardboard, packaging material, medications, fluids, and other materials (FIGURE 1).

The WHO also notes that of all the waste generated by health care activities, about 85% is general, nonhazardous waste that is comparable to domestic waste.⁶ Hazardous waste is any material that poses a health risk, including potentially infectious materials, such as blood-soaked gauze, sharps, pharmaceuticals, or radioactive materials.⁶

Disposal of hazardous waste is expensiveand energy consuming as it is typically incinerated rather than disposed of in a landfill. This process produces substantial greenhouse gases, about 3 kg of carbon dioxide for every 1 kg of hazardous waste.⁷

Red bags are used for hazardous waste disposal, while clear bags are used for general waste. Operating rooms produce about two-thirds of the hospital red-bag waste.⁸ Waste segregation unfortunately is not accurate, and as much as 90% of OR general waste is improperly designated as hazardous waste.³ Drapes and uncontaminated, needleless syringes, for example, should be disposed of in clear bags, but often they are instead directed to the red-bag and sharps container (FIGURE 2).

Recycling in the OR

Recycling has become an established practice in many health care facilities and ORs. Studies suggest that introducing recycling programs in ORs not only reduces carbon footprints but also reduces costs.³ One study reported that US academic medical centers consume 2 million lb ($15 million) each year of recoverable medical supplies.⁹

Single-stream recycling, a system in which all recyclable material—including plastics, paper, metal, and glass—are placed in a single bin without segregation at the collection site, has gained in popularity. Recycling can be implemented both in ORs and in other perioperative areas where regular trash bins are located.

In a study done at Oxford University Hospitals in the United Kingdom, introducing recycling bins in every OR, as well as in recovery and staff rest areas, helped improve waste segregation such that approximately 22% of OR waste was recycled.¹⁰ Studies show that recycling programs not only decrease the health care carbon footprint but also have a considerable financial impact. Albert and colleagues demonstrated that introducing a single-stream recycling program to a 9-OR day (or ambulatory) surgery center could redirect more than 4 tons of waste each month and saved thousands of dollars.¹¹

Despite continued improvement in recycling programs, the segregation process is still far from optimal. In a survey done at the Mayo Clinic by Azouz and colleagues, more than half of the staff reported being unclear about which OR items are recyclable and nearly half reported that lack of knowledge was the barrier to proper recycling.¹² That study also showed that after implementation of a recycling education program, costs decreased 10% relative to the same time period in prior years.¹²

Blue wraps. One example of recycling optimization is blue wraps, the polypropylene (No. 5 plastic) material used for wrapping surgical instruments. Blue wraps account for approximately 19% of OR waste and 5% of all hospital waste.¹¹ Blue wraps are not biodegradable and also are not widely recycled. In recent years, a resale market has emerged for blue wraps, as they can be used for production of other No. 5 plastic items.⁹ By reselling blue wraps, revenue can be generated by recycling a necessary packing material that would otherwise require payment for disposal.

Sterility considerations. While recycling in ORs may raise concern due to the absolute sterility required in procedural settings, technologic developments have been promising in advancing safe recycling to reduce carbon footprints and health care costs without compromising patients’ safety. Segregation of waste from recyclable packaging material prior to the case, as well as directing trash to the correct bin (regular vs red bin), is one example. Moreover, because about 80% of all OR waste is generated during the set up before the patient arrives in the OR, it is not contaminated and can be safely recycled.¹³

Packaging material

A substantial part of OR waste consists of packaging material; of all OR waste, 26% consists of plastics and 7%, paper and cartons.¹⁴ Increasing use of disposable or “single use” medical products in ORs, along with the intention to safeguard sterility, contributes significantly to the generation of medical waste in operating units. Containers, wraps and overwraps, cardboard, and plastic packaging are all composed of materials that when clean, can be recycled; however, these items often end up in the landfill (FIGURE 3).

Although the segregation of packaging material to recycling versus regular trash versus red bin is of paramount importance, packaging design plays a significant role as well. In 2018, Boston Scientific introduced a new packaging design for ureteral stents that reduced plastic use in packaging by 120,000 lb each year.¹⁵ Despite the advances in the medical packaging industry to increase sustainability while safeguarding sterility for medical devices, there is still room for innovation in this area.

Reducing overage by judicious selection of surgical devices, instruments, and supplies

Overage is the term used to describe surgical inventory that is opened and prepared for surgery but ultimately not used and therefore discarded. Design of surgical carts and instrument and supply selection requires direct input from ObGyns. Opening only the needed instruments while ensuring ready availability of potentially needed supplies can significantly reduce OR waste generation as well as decrease chemical pollution generated by instrument sterilization. Decreasing OR overage reduces overall costs as well (FIGURE 4).

In a pilot study at the University of Massachusetts, Albert and colleagues examined the sets of disposable items and instruments designated for common plastic and hand surgery procedures.¹¹ They identified the supplies and instruments that are routinely opened and wasted, based on surgeons’ interview responses, and redesigned the sets. Fifteen items were removed from disposable plastic surgery packs and 7 items from hand surgery packs. The authors reported saving thousands of dollars per year with these changes alone, as well as reducing waste.¹¹ This same concept easily could be implemented in obstetrics and gynecology. We must ask ourselves: Do we always need, for example, a complete dilation and curettage kit to place the uterine manipulator prior to a minimally invasive hysterectomy?

In another pilot study, Greenberg and colleagues investigated whether cesarean deliveries consistently could be performed in a safe manner with only 20 instruments in the surgical kit.¹⁶ Obstetricians rated the 20-instrument kit an 8.7 out of 10 for performing cesarean deliveries safely.¹⁶

In addition to instrument selection, surgeons have a role in other supply use and waste generation: for instance, opening multiple pairs of surgical gloves and surgical gowns in advance when most of them will not be used during the case. Furthermore, many ObGyn surgeons routinely change gloves or even gowns during gynecologic procedures when they go back and forth between the vaginal and abdominal fields. Is the perineum “dirty” after application of a surgical prep solution?

In an observational study, Shockley and colleagues investigated the type and quantity of bacteria found intraoperatively on the abdomen, vagina, surgical gloves, instrument tips, and uterus at distinct time points during total laparoscopic hysterectomy.¹⁷ They showed that in 98.9% of cultures, the overall bacterial concentrations did not exceed the threshold for infection. There was no bacterial growth from vaginal cultures, and the only samples with some bacterial growth belonged to the surgeon’s gloves after specimen extraction; about one-third of samples showed growth after specimen extraction, but only 1 sample had a bacterial load above the infectious threshold of 5,000 colony-forming units per mL. The authors therefore suggested that if a surgeon changes gloves, doing so after specimen extraction and before turning attention back to the abdomen for vaginal cuff closure may be most effective in reducing bacterial load.¹⁷

Surgical site infection contributes to medical cost and likely medical waste as well. For example, surgical site infection may require prolonged treatments, tests, and medical instruments. In severe cases with abscesses, treatment entails hospitalization with prolonged antibiotic therapy with or without procedures to drain the collections. Further research therefore is warranted to investigate safe and environmentally friendly practices.

Myriad products are introduced to the medical system each day, some of which replace conventional tools. For instance, low-density polyethylene, or LDPE, transfer sheet is advertised for lateral patient transfer from the OR table to the bed or stretcher. This No. 4–coded plastic, while recyclable, is routinely discarded as trash in ORs. One ergonomic study found that reusable slide boards are as effective for reducing friction and staff muscle activities and are noninferior to the plastic sheets.¹⁸

Steps to making an impact

Operating rooms and labor and delivery units are responsible for a large proportion of hospital waste, and therefore they are of paramount importance in reducing waste and carbon footprint at the individual and institutional level. Reduction of OR waste not only is environmentally conscious but also decreases cost. Steps as small as individual practices to as big as changing infrastructures can make an impact. For instance:

• redesigning surgical carts
• reformulating surgeon-specific supply lists
• raising awareness about surgical overage
• encouraging recycling through education and audit
• optimizing surgical waste segregation through educational posters.

These are all simple steps that could significantly reduce waste and carbon footprint.

Bottom line

Although waste reduction is the responsibility of all health care providers, as leaders in their workplace physicians can serve as role models by implementing “green” practices in procedural units. Raising awareness and using a team approach is critical to succeed in our endeavors to move toward an environmentally friendly future. ●

Have you ever looked at the operating room (OR) trash bin at the end of a case and wondered if all that waste is necessary? Since I started my residency, not a day goes by that I have not asked myself this question.

In the mid-1990s, John Elkington introduced the concept of the triple bottom line—that is, people, planet, and profit—for implementation and measurement of sustainability in businesses.¹ The health care sector is no exception when it comes to the bottom line! However, “people” remain the priority. What is our role, as ObGyns, in protecting the “planet” while keeping the “people” safe?

According to the World Health Organization (WHO), climate change remains the single biggest health threat to humanity.² The health care system is both the victim and the culprit. Studies suggest that the health care system, second to the food industry, is the biggest contributor to waste production in the United States. This sector generates more than 6,000 metric tons of waste each day and nearly 4 million tons (3.6 million metric tons) of solid waste each year.³ The health care system is responsible for an estimated 8% to 10% of total greenhouse gas emissions in the United States; the US health care system alone contributes to more than one-fourth of the global health care carbon footprint. If it were a country, the US health care system would rank 13th among all countries in emissions.⁴In turn, pollution produced by the health sector negatively impacts population health, further burdening the health care system. According to 2013 study data, the annual health damage caused by health care pollution was comparable to that of the deaths caused by preventable medical error.⁴

Aside from the environmental aspects, hospital waste disposal is expensive; reducing this cost is a potential area of interest for institutions.

As ObGyns, what is our role in reducing our waste generation and carbon footprint while keeping patients safe?

Defining health care waste, and disposal considerations

The WHO defines health care waste as including “the waste generated by health-care establishments, research facilities, and laboratories” as well as waste from scattered sources such as home dialysis and insulin injections.⁵ Despite representing a relatively small physical area of hospitals, labor and delivery units combined with ORs account for approximately 70% of all hospital waste.³ Operating room waste consists of disposable surgical supplies, personal protective equipment, drapes, plastic wrappers, sterile blue wraps, glass, cardboard, packaging material, medications, fluids, and other materials (FIGURE 1).

The WHO also notes that of all the waste generated by health care activities, about 85% is general, nonhazardous waste that is comparable to domestic waste.⁶ Hazardous waste is any material that poses a health risk, including potentially infectious materials, such as blood-soaked gauze, sharps, pharmaceuticals, or radioactive materials.⁶

Disposal of hazardous waste is expensiveand energy consuming as it is typically incinerated rather than disposed of in a landfill. This process produces substantial greenhouse gases, about 3 kg of carbon dioxide for every 1 kg of hazardous waste.⁷

Red bags are used for hazardous waste disposal, while clear bags are used for general waste.

Understanding more about the gut microbiome and how it may affect the development and treatment of heart failure could lead to a more personalized approach to managing the condition, a new review article suggests.

ChrisChrisW/Getty Images

“The gut microbiome modulates heart failure pathophysiology, contributes to disease progression and therapeutic responses, and holds promise as a novel biomarker,” the authors note. “Interactions among the gut microbiome, diet, and medications offer potentially innovative modalities for management of patients with heart failure,” they add.

The review was published online in the Journal of the American College of Cardiology.

“Over the past years we have gathered more understanding about how important the gut microbiome is in relation to how our bodies function overall and even though the cardiovascular system and the heart itself may appear to be quite distant from the gut, we know the gut microbiome affects the cardiovascular system and the physiology of heart failure,” lead author Petra Mamic, MD, Stanford (Calif.) University, told this news organization.

“We’ve also learnt that the microbiome is very personalized. It seems to be affected by a lot of intrinsic and as well as extrinsic factors. For cardiovascular diseases in particular, we always knew that diet and lifestyle were part of the environmental risk, and we now believe that the gut microbiome may be one of the factors that mediates that risk,” she said.

“Studies on the gut microbiome are difficult to do and we are right at the beginning of this type of research. But we have learned that the microbiome is altered or dysregulated in many diseases including many cardiovascular diseases, and many of the changes in the microbiome we see in different cardiovascular diseases seem to overlap,” she added.

Dr. Mamic explained that patients with heart failure have a microbiome that appears different and dysregulated, compared with the microbiome in healthy individuals.

“The difficulty is teasing out whether the microbiome changes are causing heart failure or if they are a consequence of the heart failure and all the medications and comorbidities associated with heart failure,” she commented.

Animal studies have shown that many microbial products, small molecules made by the microbiome, seem to affect how the heart recovers from injury, for example after a myocardial infarction, and how much the heart scars and hypertrophies after an injury, Dr. Mamic reported. These microbiome-derived small molecules can also affect blood pressure, which is dysregulated in heart failure.

Other products of the microbiome can be pro-inflammatory or anti-inflammatory, which can again affect the cardiovascular physiology and the heart, she noted.
 

High-fiber diet may be beneficial

One area of particular interest at present involves the role of short-chain fatty acids, which are a byproduct of microbes in the gut that digest fiber.

“These short chain fatty acids seem to have positive effects on the host physiology. They are anti-inflammatory; they lower blood pressure; and they seem to protect the heart from scarring and hypertrophy after injury. In heart failure, the gut microbes that make these short-chain fatty acids are significantly depleted,” Dr. Mamic explained.

They are an obvious focus of interest because these short-chain fatty acids are produced when gut bacteria break down dietary fiber, raising the possibility of beneficial effects from eating a high-fiber diet.

Another product of the gut microbiome of interest is trimethylamine N-oxide, formed when gut bacteria break down nutrients such as L-carnitine and phosphatidyl choline, nutrients abundant in foods of animal origin, especially red meat. This metabolite has proatherogenic and prothrombotic effects, and negatively affected cardiac remodeling in a mouse heart failure model, the review notes.

However, though it is too early to make specific dietary recommendations based on these findings, Dr. Mamic points out that a high-fiber diet is thought to be beneficial.

“Nutritional research is very hard to do and the data is limited, but as best as we can summarize things, we know that plant-based diets such as the Mediterranean and DASH diets seem to prevent some of the risk factors for the development of heart failure and seem to slow the progression of heart failure,” she added.

One of the major recommendations in these diets is a high intake of fiber, including whole foods, vegetables, fruits, legumes, and nuts, and less intake of processed food and red meat. “In general, I think everyone should eat like that, but I specifically recommend a plant-based diet with a high amount of fiber to my heart failure patients,” Dr. Mamic said.
 

Large variation in microbiome composition

The review also explores the idea of personalization of diet or specific treatments dependent on an individual’s gut microbiome composition.

Dr. Mamic explains: “When we look at the microbiome composition between individuals, it is very different. There is very little overlap between individuals, even in people who are related. It seems to be more to do with the environment – people who are living together are more likely to have similarities in their microbiome. We are still trying to understand what drives these differences.”

It is thought that these differences may affect the response to a specific diet or medication. Dr. Mamic gives the example of fiber. “Not all bacteria can digest the same types of fiber, so not everyone responds in the same way to a high-fiber diet. That’s probably because of differences in their microbiome.”

Another example is the response to the heart failure drug digoxin, which is metabolized by one particular strain of bacteria in the gut. The toxicity or effectiveness of digoxin seems to be influenced by levels of this bacterial strain, and this again can be influenced by diet, Dr. Mamic says.
 

Manipulating the microbiome as a therapeutic strategy

Microbiome-targeting therapies may also become part of future treatment strategies for many conditions, including heart failure, the review authors say.

Probiotics (foods and dietary supplements that contain live microbes) interact with the gut microbiota to alter host physiology beneficially. Certain probiotics may specifically modulate processes dysregulated in heart failure, as was suggested in a rodent heart failure model in which supplementation with Lactobacillus-containing and Bifidobacterium-containing probiotics resulted in markedly improved cardiac function, the authors report.

However, a randomized trial (GutHeart) of probiotic yeast Saccharomyces boulardii in patients with heart failure found no improvement in cardiac function, compared with standard care.

Commenting on this, Dr. Mamic suggested that a more specific approach may be needed.

“Some of our preliminary data have shown people who have heart failure have severely depleted Bifidobacteria,” Dr. Mamic said. These bacteria are commercially available as a probiotic, and the researchers are planning a study to give patients with heart failure these specific probiotics. “We are trying to find practical ways forward and to be guided by the data. These people have very little Bifidobacteria, and we know that probiotics seem to be accepted best by the host where there is a specific need for them, so this seems like a sensible approach.”

Dr. Mamic does not recommend that heart failure patients take general probiotic products at present, but she tells her patients about the study she is doing. “Probiotics are quite different from each other. It is a very unregulated market. A general probiotic product may not contain the specific bacteria needed.”
 

Include microbiome data in biobanks

The review calls for more research on the subject and a more systematic approach to collecting data on the microbiome.

“At present for medical research, blood samples are collected, stored, and analyzed routinely. I think we should also be collecting stool samples in the same way to analyze the microbiome,” Dr. Mamic suggests.

“If we can combine that with data from blood tests on various metabolites/cytokines and look at how the microbiome changes over time or with medication, or with diet, and how the host responds including clinically relevant data, that would be really important. Given how quickly the field is growing I would think there would be biobanks including the microbiome in a few years’ time.”

“We need to gather this data. We would be looking for which bacteria are there, what their functionality is, how it changes over time, with diet or medication, and even whether we can use the microbiome data to predict who will respond to a specific drug.”

Dr. Mamic believes that in the future, analysis of the microbiome could be a routine part of deciding what people eat for good health and to characterize patients for personalized therapies.

“It is clear that the microbiome can influence health, and a dysregulated microbiome negatively affects the host, but there is lot of work to do. We need to learn a lot more about it, but we shouldn’t miss the opportunity to do this,” she concluded.

Dr. Mamic reported no disclosures.

Understanding more about the gut microbiome and how it may affect the development and treatment of heart failure could lead to a more personalized approach to managing the condition, a new review article suggests.

“The gut microbiome modulates heart failure pathophysiology, contributes to disease progression and therapeutic responses, and holds promise as a novel biomarker,” the authors note. “Interactions among the gut microbiome, diet, and medications offer potentially innovative modalities for management of patients with heart failure,” they add.

The review was published online in the Journal of the American College of Cardiology.

“Over the past years we have gathered more understanding about how important the gut microbiome is in relation to how our bodies function overall and even though the cardiovascular system and the heart itself may appear to be quite distant from the gut, we know the gut microbiome affects the cardiovascular system and the physiology of heart failure,” lead author Petra Mamic, MD, Stanford (Calif.) University, told this news organization.

“We’ve also learnt that the microbiome is very personalized. It seems to be affected by a lot of intrinsic and as well as extrinsic factors. For cardiovascular diseases in particular, we always knew that diet and lifestyle were part of the environmental risk, and we now believe that the gut microbiome may be one of the factors that mediates that risk,” she said.

“Studies on the gut microbiome are difficult to do and we are right at the beginning of this type of research. But we have learned that the microbiome is altered or dysregulated in many diseases including many cardiovascular diseases, and many of the changes in the microbiome we see in different cardiovascular diseases seem to overlap,” she added.

Dr. Mamic explained that patients with heart failure have a microbiome that appears different and dysregulated, compared with the microbiome in healthy individuals.

“The difficulty is teasing out whether the microbiome changes are causing heart failure or if they are a consequence of the heart failure and all the medications and comorbidities associated with heart failure,” she commented.

Animal studies have shown that many microbial products, small molecules made by the microbiome, seem to affect how the heart recovers from injury, for example after a myocardial infarction, and how much the heart scars and hypertrophies after an injury, Dr. Mamic reported. These microbiome-derived small molecules can also affect blood pressure, which is dysregulated in heart failure.

Other products of the microbiome can be pro-inflammatory or anti-inflammatory, which can again affect the cardiovascular physiology and the heart, she noted.
 

High-fiber diet may be beneficial

One area of particular interest at present involves the role of short-chain fatty acids, which are a byproduct of microbes in the gut that digest fiber.

“These short chain fatty acids seem to have positive effects on the host physiology. They are anti-inflammatory; they lower blood pressure; and they seem to protect the heart from scarring and hypertrophy after injury. In heart failure, the gut microbes that make these short-chain fatty acids are significantly depleted,” Dr. Mamic explained.

They are an obvious focus of interest because these short-chain fatty acids are produced when gut bacteria break down dietary fiber, raising the possibility of beneficial effects from eating a high-fiber diet.

Another product of the gut microbiome of interest is trimethylamine N-oxide, formed when gut bacteria break down nutrients such as L-carnitine and phosphatidyl choline, nutrients abundant in foods of animal origin, especially red meat. This metabolite has proatherogenic and prothrombotic effects, and negatively affected cardiac remodeling in a mouse heart failure model, the review notes.

However, though it is too early to make specific dietary recommendations based on these findings, Dr. Mamic points out that a high-fiber diet is thought to be beneficial.

“Nutritional research is very hard to do and the data is limited, but as best as we can summarize things, we know that plant-based diets such as the Mediterranean and DASH diets seem to prevent some of the risk factors for the development of heart failure and seem to slow the progression of heart failure,” she added.

Taking a swing against arthritis

Osteoarthritis is a tough disease to manage. Exercise helps ease the stiffness and pain of the joints, but at the same time, the disease makes it difficult to do that beneficial exercise. Even a relatively simple activity like jogging can hurt more than it helps. If only there were a low-impact exercise that was incredibly popular among the generally older population who are likely to have arthritis.

We love a good golf study here at LOTME, and a group of Australian and U.K. researchers have provided. Osteoarthritis affects 2 million people in the land down under, making it the most common source of disability there. In that population, only 64% reported their physical health to be good, very good, or excellent. Among the 459 golfers with OA that the study authors surveyed, however, the percentage reporting good health rose to more than 90%.

A similar story emerged when they looked at mental health. Nearly a quarter of nongolfers with OA reported high or very high levels of psychological distress, compared with just 8% of golfers. This pattern of improved physical and mental health remained when the researchers looked at the general, non-OA population.

This isn’t the first time golf’s been connected with improved health, and previous studies have shown golf to reduce the risks of cardiovascular disease, diabetes, and obesity, among other things. Just walking one 18-hole round significantly exceeds the CDC’s recommended 150 minutes of physical activity per week. Go out multiple times a week – leaving the cart and beer at home, American golfers – and you’ll be fit for a lifetime.

The golfers on our staff, however, are still waiting for those mental health benefits to kick in. Because when we’re adding up our scorecard after that string of four double bogeys to end the round, we’re most definitely thinking: “Yes, this sport is reducing my psychological distress. I am having fun right now.”
 

Battle of the sexes’ intestines

There are, we’re sure you’ve noticed, some differences between males and females. Females, for one thing, have longer small intestines than males. Everybody knows that, right? You didn’t know? Really? … Really?

Afif Ramdhasuma/Unsplash

Well, then, we’re guessing you haven’t read “Hidden diversity: Comparative functional morphology of humans and other species” by Erin A. McKenney, PhD, of North Carolina State University, Raleigh, and associates, which just appeared in PeerJ. We couldn’t put it down, even in the shower – a real page-turner/scroller. (It’s a great way to clean a phone, for those who also like to scroll, text, or talk on the toilet.)

The researchers got out their rulers, calipers, and string and took many measurements of the digestive systems of 45 human cadavers (21 female and 24 male), which were compared with data from 10 rats, 10 pigs, and 10 bullfrogs, which had been collected (the measurements, not the animals) by undergraduate students enrolled in a comparative anatomy laboratory course at the university.

There was little intestinal-length variation among the four-legged subjects, but when it comes to humans, females have “consistently and significantly longer small intestines than males,” the investigators noted.

The women’s small intestines, almost 14 feet long on average, were about a foot longer than the men’s, which suggests that women are better able to extract nutrients from food and “supports the canalization hypothesis, which posits that women are better able to survive during periods of stress,” coauthor Amanda Hale said in a written statement from the school. The way to a man’s heart may be through his stomach, but the way to a woman’s heart is through her duodenum, it seems.

Fascinating stuff, to be sure, but the thing that really caught our eye in the PeerJ article was the authors’ suggestion “that organs behave independently of one another, both within and across species.” Organs behaving independently? A somewhat ominous concept, no doubt, but it does explain a lot of the sounds we hear coming from our guts, which can get pretty frightening, especially on chili night.
 

Dog walking is dangerous business

Yes, you did read that right. A lot of strange things can send you to the emergency department. Go ahead and add dog walking onto that list.

Investigators from Johns Hopkins University estimate that over 422,000 adults presented to U.S. emergency departments with leash-dependent dog walking-related injuries between 2001 and 2020.

freestocks/Unsplash

With almost 53% of U.S. households owning at least one dog in 2021-2022 in the wake of the COVID pet boom, this kind of occurrence is becoming more common than you think. The annual number of dog-walking injuries more than quadrupled from 7,300 to 32,000 over the course of the study, and the researchers link that spike to the promotion of dog walking for fitness, along with the boost of ownership itself.

The most common injuries listed in the National Electronic Injury Surveillance System database were finger fracture, traumatic brain injury, and shoulder sprain or strain. These mostly involved falls from being pulled, tripped, or tangled up in the leash while walking. For those aged 65 years and older, traumatic brain injury and hip fracture were the most common.

Women were 50% more likely to sustain a fracture than were men, and dog owners aged 65 and older were three times as likely to fall, twice as likely to get a fracture, and 60% more likely to have brain injury than were younger people. Now, that’s not to say younger people don’t also get hurt. After all, dogs aren’t ageists. The researchers have that data but it’s coming out later.

Meanwhile, the pitfalls involved with just trying to get our daily steps in while letting Muffin do her business have us on the lookout for random squirrels.

(It’s a great way to clean a phone, for those who also like to scroll, text, or talk on the toilet.)

The researchers got out their rulers, calipers, and string and took many measurements of the digestive systems of 45 human cadavers (21 female and 24 male), which were compared with data from 10 rats, 10 pigs, and 10 bullfrogs, which had been collected (the measurements, not the animals) by undergraduate students enrolled in a comparative anatomy laboratory course at the university.

There was little intestinal-length variation among the four-legged subjects, but when it comes to humans, females have “consistently and significantly longer small intestines than males,” the investigators noted.

The women’s small intestines, almost 14 feet long on average, were about a foot longer than the men’s, which suggests that women are better able to extract nutrients from food and “supports the canalization hypothesis, which posits that women are better able to survive during periods of stress,” coauthor Amanda Hale said in a written statement from the school. The way to a man’s heart may be through his stomach, but the way to a woman’s heart is through her duodenum, it seems.

Fascinating stuff, to be sure, but the thing that really caught our eye in the PeerJ article was the authors’ suggestion “that organs behave independently of one another, both within and across species.” Organs behaving independently? A somewhat ominous concept, no doubt, but it does explain a lot of the sounds we hear coming from our guts, which can get pretty frightening, especially on chili night.
 

Dog walking is dangerous business

Yes, you did read that right. A lot of strange things can send you to the emergency department. Go ahead and add dog walking onto that list.

Investigators from Johns Hopkins University estimate that over 422,000 adults presented to U.S. emergency departments with leash-dependent dog walking-related injuries between 2001 and 2020.

With almost 53% of U.S. households owning at least one dog in 2021-2022 in the wake of the COVID pet boom, this kind of occurrence is becoming more common than you think. The annual number of dog-walking injuries more than quadrupled from 7,300 to 32,000 over the course of the study, and the researchers link that spike to the promotion of dog walking for fitness, along with the boost of ownership itself.

The most common injuries listed in the National Electronic Injury Surveillance System database were finger fracture, traumatic brain injury, and shoulder sprain or strain. These mostly involved falls from being pulled, tripped, or tangled up in the leash while walking. For those aged 65 years and older, traumatic brain injury and hip fracture were the most common.

Women were 50% more likely to sustain a fracture than were men, and dog owners aged 65 and older were three times as likely to fall, twice as likely to get a fracture, and 60% more likely to have brain injury than were younger people. Now, that’s not to say younger people don’t also get hurt. After all, dogs aren’t ageists. The researchers have that data but it’s coming out later.

Meanwhile, the pitfalls involved with just trying to get our daily steps in while letting Muffin do her business have us on the lookout for random squirrels.
