Patients with iron deficiency anemia who developed bacterial pneumonia showed improved outcomes compared to those without iron deficiency anemia, based on data from more than 450,000 individuals in the National Inpatient Sample.

Iron deficiency is the most common nutritional deficiency worldwide, and can lead to anemia, but iron also has been identified as essential to the survival and growth of pathogenic organisms, Mubarak Yusuf, MD, said in a presentation at the annual meeting of the American College of Chest Physicians (CHEST).

However, the specific impact of iron deficiency anemia (IDA) on outcomes in patients hospitalized with acute bacterial infections has not been explored, said Dr. Yusuf, a third-year internal medicine resident at Lincoln Medical Center in New York.

In the study, Dr. Yusuf and colleagues reviewed data from the Nationwide Inpatient Sample (NIS) Database for 2016-2019. They identified 452,040 adults aged 18 or older with a primary diagnosis of bacterial pneumonia based on ICD-10 codes. Patients with a principal diagnosis other than bacterial pneumonia were excluded.

Of these, 5.5% had a secondary diagnosis of IDA. The mean age of the study population was similar between the IDA and non-IDA groups (68 years) and racial distribution was similar, with a White majority of approximately 77%. Slightly more patients in the IDA group were women (58.5% vs. 51.6%) and this difference was statistically significant (P < .00001). Most of the patients (94.6%) in the IDA group had at least three comorbidities, as did 78.1% of the non-IDA group.

The primary outcome was mortality, and the overall mortality in the study population was 2.89%. Although the mortality percentage was higher in the IDA group compared to the non-IDA group (3.25% vs. 2.87%), “when we adjusted for confounders, we noticed a decreased odds of mortality in the IDA group” with an adjusted odds ratio of 0.74 (P = .001), Dr. Yusuf said.

In addition, secondary outcomes of septic shock, acute respiratory failure, and cardiac arrest were lower in the IDA group in a regression analysis, with adjusted odds ratios of 0.71, 0.78, and 0.57, respectively.

The mean length of stay was 0.3 days higher in the IDA group, and the researchers found a nonsignificant increase in total hospital costs of $402.5 for IDA patients compared to those without IDA, said Dr. Yusuf.

The take-home message from the study is actually a question to the clinician, Dr. Yusuf said. “Should you consider a delay in treatment [of iron deficiency anemia] if the patient is not symptomatic?” he asked.

More research is needed to investigate the improved outcomes in the iron deficient population, but the large sample size supports an association that is worth exploring, he concluded.

“The findings of this research may suggest a protective effect of iron deficiency in acute bacterial pneumonia,” Dr. Yusuf said in a press release accompanying the meeting presentation. “More research is needed to elucidate the improved outcomes found in this population, but this research may lead clinicians to consider a delay in treatment of nonsymptomatic iron deficiency in acute bacterial infection,” he added.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Mental health symptoms at the time of admission to an inpatient psychiatric hospital were significantly more severe during the COVID-19 pandemic compared to the time before the pandemic, based on data from more than 500 individuals.

“Those with preexisting mental health conditions may be particularly vulnerable to these effects because they are more susceptible to experiencing high levels of stress during a crisis and are more likely to experience isolation/despair during confinement compared to the general population,” wrote Danna Ramirez of The Menninger Clinic, Houston, and colleagues.

In a study published in Psychiatry Research , the investigators compared data from 142 adolescents aged 12-17 years and 470 adults aged 18-79 years who were admitted to an inpatient psychiatric hospital in Houston. Of these, 65 adolescents and 235 adults were admitted before the pandemic, and 77 adolescents and 235 adults were admitted during the pandemic.

Clinical outcomes were scores on the Generalized Anxiety Disorder Scale (GAD-7), the Patient Health Questionnaire (PHQ-9), the Patient Health Questionnaire for Adolescents (PHQ-A), the Difficulties in Emotion Regulation Scale–Short Form (DERS-SF), the World Health Organization Disability Assessment Scale (WHODAS), the World Health Organization Alcohol, Smoking, and Substance Involvement Screening Test (WHOASSIST), the Pittsburgh Sleep Quality Index (PSQI), the Disturbing Dream and Nightmare Severity Index (DDNSI), and the Suicide Behaviors Questionnaire–Revised (SBQ-R).

Overall, adults admitted during the pandemic had significantly higher levels of anxiety, depression, emotional dysregulation, and disability (P < .001 for all) as well as nightmares (P = .013) compared to those admitted prior to the pandemic.

Among adolescents, measures of anxiety, depression, and sleep quality were significantly higher at admission during the pandemic compared to prior to the pandemic (P = .005, P = .005, and P = .011, respectively)

Reasons for the increase in symptom severity remain unclear, but include the possibility that individuals with preexisting mental illness simply became more ill; or that individuals with symptoms delayed hospital admission out of fear of exposure to COVID-19, which resulted in more severe symptoms at admission, the researchers wrote in their discussion.

The findings were limited by several factors, including the primarily White population and the reliance on self-reports, the researchers noted. Another limitation was the lack of differentiation between patients who may have had COVID-19 before hospitalization and those who did not, so the researchers could not determine whether the virus itself played a biological role in symptom severity.

However, the results support data from previous studies and identify increased psychiatry symptom severity for patients admitted for inpatient psychiatry care during the pandemic, they said. Although resources are scarce, the findings emphasize that mental health needs, especially for those with preexisting conditions, should not be overlooked, and continuity and expansion of access to mental health care for all should be prioritized, they concluded.

The study was supported by The Menninger Clinic and The Menninger Clinic Foundation. The researchers had no financial conflicts to disclose.

A majority of hospitalized patients at low risk for venous thromboembolism were unnecessarily treated with medication, based on data from more than 400 individuals.

Prevention of venous thromboembolism (VTE) is important, and current guidelines from the American College of Chest Physicians suggest that patients with high or moderate risk for VTE be treated with mechanical prophylaxis, and that pharmacological prophylaxis is not recommended for patients at high risk for bleeding, said Hui Chong Lau, MD, in a presentation at the annual meeting of the American College of Chest Physicians (CHEST).

However, the nature of VTE prophylaxis using a risk assessment score has not been explored, said Dr. Lau, a third-year resident in internal medicine at Crozer-Chester Medical Center, Upland, Penn.

Low-molecular-weight heparin (LWMH) and intermittent pneumatic compression are often used to reduce VTE risk during hospitalization, but for patients with low VTE risk, prophylaxis is not necessarily recommended, he said. In fact, overuse of chemical prophylaxis in low-risk patients can increase bleeding risk and contribute to patient discomfort in the form of additional needle sticks while hospitalized, Dr. Lau said in the presentation.

“We wanted to see how well physicians in the hospital used a risk assessment model to stratify patients,” and how well the patients were assigned to the correct prophylaxis, he explained.

Dr. Lau and colleagues reviewed data from 469 adult patients hospitalized at a single medical center who were hospitalized between January 2021 and June 2021. The researchers retrospectively performed risk assessment using the Padua prediction score. A score of less than 4 was considered low risk for VTE, and a score of 4 or higher was considered high risk.

In the study population, 180 patients were identified as low risk and 289 were considered high risk.

Based on the Padua score, 95% of the patients at high risk were on the correct prophylaxis, Dr. Lau said.

A total of 193 high-risk patients were on heparin. However, many of these patients had good kidney function, and could have been treated with enoxaparin instead; “this would have spared them two needle sticks per day,” Dr. Lau noted.

Of the 180 low-risk patients, 168 (93.3%) were on chemical prophylaxis, and should have been on mechanical prophylaxis, he said. Only 10 patients (5%) who were considered low risk were placed on mechanical prophylaxis.

Overall, 3.6% of all patients who received chemical VTE prophylaxis developed bleeding.

The results were limited by the retrospective design and use of data from a single center. However, the findings emphasize the need for better attention to VTE risk when considering prophylaxis, said Dr. Lau. “We have to have risk assessment every day,” during a hospital stay, and adjust treatment accordingly, he said.

“We are likely overusing chemical VTE prophylaxis in low-risk patients,” he concluded.

Additional research is needed to better understand the potential consequences of overusing chemical VTE, including not only bleeding risk, but also financial costs and patient discomfort, he said.

The number of adults hospitalized with ventilator-associated pneumonia (VAP) in the United States increased by 50% from 2013 to 2019, based on data from the National Inpatient Sample.

Health care–associated infections are a significant burden, and “ventilator associated-pneumonia is a contributor to that,” said Namratha S. Meda, MBBS, in a presentation at the annual meeting of the American College of Chest Physicians.

VAP can affect length of stay and other costs, but factors related to VAP hospitalization have not been well studied, said Dr. Meda, of Medstar Health/Georgetown University Hospital, Washington.

To examine trends in hospitalization for VAP, Dr. Meda and colleagues reviewed data from the National Inpatient Sample from January 2013 to December 2019. The study population included adult patients with VAP as a primary or secondary diagnosis based on ICD-9 or ICD-10 codes.

Overall, the trend in hospitalizations showed a consistent increase, said Dr. Meda.

The researchers identified 128,025 adult hospitalizations with VAP during the study period, with an increase from 50 VAP cases per 100,000 hospitalizations in 2013 to 75 cases per 100,000 hospitalizations in 2019.

A total of 42,120 hospitalizations were associated with tracheostomy, ventilator dependence, or both. Hospitalizations in these categories increased by 80% during the study period, from 15 cases per 100,000 hospitalizations in 2013 to 27 cases per 100,000 hospitalizations in 2019.

The median cost for each hospitalization was $83,311, and showed a 2.9% increase from 2013 to 2019. The estimated annual cost of VAP hospitalizations was approximately $2.8 billion in 2019, Dr. Meda emphasized. However, all-cause hospital mortality remained unchanged over the study period, at approximately 20%.

The mean age of the hospitalized VAP patients was 58 years across all VAP-related hospitalizations, and 36.5% were women. More than half (58%) were White, 21% were Black, and 12% were Hispanic.

The researchers noted some sex and racial disparities; the median age was lower for Black and Hispanic patients, compared with White patients, but all-cause mortality was lower. Men had a significantly longer median length of stay, compared with women (21 days vs. 19 days), and higher median costs ($87,981 vs. $74,889) with a P <.001 for both, but the all-cause in-hospital mortality was not significantly different between sexes.

The steady increase in hospitalization for VAP without a significant change in all-cause mortality, might be driven by hospitals with higher levels of tracheostomy and ventilator dependence, but more research is needed, Dr. Meda noted.

The study was limited by the observational design, which allowed the researchers to report an association, but not causality, said Dr. Meda. However, the results reflect the ongoing financial burden of VAP on the health care system, although “it would be interesting to see how the trend might change if we just looked at the clinical definition versus billing data,” she noted.

The study did not include data since the advent of COVID-19, but COVID is likely to drive the trend of increasing VAP hospitalization higher, Dr. Meda added.

To examine trends in hospitalization for VAP, Dr. Meda and colleagues reviewed data from the National Inpatient Sample from January 2013 to December 2019. The study population included adult patients with VAP as a primary or secondary diagnosis based on ICD-9 or ICD-10 codes.

Overall, the trend in hospitalizations showed a consistent increase, said Dr. Meda.

The researchers identified 128,025 adult hospitalizations with VAP during the study period, with an increase from 50 VAP cases per 100,000 hospitalizations in 2013 to 75 cases per 100,000 hospitalizations in 2019.

A total of 42,120 hospitalizations were associated with tracheostomy, ventilator dependence, or both. Hospitalizations in these categories increased by 80% during the study period, from 15 cases per 100,000 hospitalizations in 2013 to 27 cases per 100,000 hospitalizations in 2019.

The median cost for each hospitalization was $83,311, and showed a 2.9% increase from 2013 to 2019. The estimated annual cost of VAP hospitalizations was approximately $2.8 billion in 2019, Dr. Meda emphasized. However, all-cause hospital mortality remained unchanged over the study period, at approximately 20%.

The mean age of the hospitalized VAP patients was 58 years across all VAP-related hospitalizations, and 36.5% were women. More than half (58%) were White, 21% were Black, and 12% were Hispanic.

The researchers noted some sex and racial disparities; the median age was lower for Black and Hispanic patients, compared with White patients, but all-cause mortality was lower. Men had a significantly longer median length of stay, compared with women (21 days vs. 19 days), and higher median costs ($87,981 vs. $74,889) with a P <.001 for both, but the all-cause in-hospital mortality was not significantly different between sexes.

The steady increase in hospitalization for VAP without a significant change in all-cause mortality, might be driven by hospitals with higher levels of tracheostomy and ventilator dependence, but more research is needed, Dr. Meda noted.

The study was limited by the observational design, which allowed the researchers to report an association, but not causality, said Dr. Meda. However, the results reflect the ongoing financial burden of VAP on the health care system, although “it would be interesting to see how the trend might change if we just looked at the clinical definition versus billing data,” she noted.

The study did not include data since the advent of COVID-19, but COVID is likely to drive the trend of increasing VAP hospitalization higher, Dr. Meda added.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Teens diagnosed with attention-deficit/hyperactivity disorder in childhood reported similar overall quality of life compared with teens with ADHD behaviors but no childhood diagnosis, a new study finds.

The results align with findings from other studies suggesting lower quality of life (QOL) in teens with ADHD, but the current study is the first known to focus on the association between ADHD diagnosis itself vs. ADHD symptoms, and QOL, the researchers wrote. The findings show that at least some of the reduced QOL is associated with the diagnosis itself, they explained.

The researchers directly compared 393 teens with a childhood ADHD diagnosis to 393 matched teens with no ADHD diagnosis but who had hyperactive/inattentive behaviors.

The researchers reviewed self-reports from individuals who were enrolled in a population-based prospective study in Australia. The primary outcome was quality of life at age 14-15, which was measured with Child Health Utility 9D (CHU9D), a validated quality of life measure.
 

Study results

Overall, teens with and without an ADHD diagnosis reported similar levels of overall quality of life; the mean difference in the primary outcome CHU9D score was –0.03 (P = .10). Teens with and without an ADHD diagnosis also showed similar scores on measures of general health, happiness, and peer trust, the researchers noted.

The researchers also reviewed eight other prespecified, self-reported measures: academic self-concept, global health, negative social behaviors, overall happiness, peer trust, psychological sense of school membership, self-efficacy, and self-harm.

Teens diagnosed with ADHD in childhood were more than twice as likely to report self-harm (odds ratio 2.53, P less than .001) and displayed significantly more negative social behaviors (mean difference 1.56, P = .002), compared with teens without an ADHD diagnosis.

Teens diagnosed with ADHD in childhood also scored significantly worse on measures of sense of school membership (mean difference −2.58, P less than .001), academic self-concept (mean difference, −0.14; P = .02), and self-efficacy (mean difference −0.20; P = .007), compared to teens without an ADHD diagnosis.

The average age at ADHD diagnosis was 10 years, and 72% of the ADHD-diagnosed group were boys. No significant differences were noted for levels of hyperactive/inattentive behaviors and between girls and boys, but girls overall and children with the highest levels of hyperactive and inattentive behaviors reported generally worse outcomes, regardless of ADHD diagnosis, the researchers noted.
 

Don’t rush to diagnosis

Although rates of ADHD diagnosis in children continue to rise, the prevalence of hyperactivity and inattentive behaviors appears stable, which suggests a problem with diagnosis, senior author Alexandra Barratt, MBBS, MPH, PhD, professor of public health at the University of Sydney, Australia, said in an interview.

“Our hypothesis was that children who had been diagnosed, and we assume treated for, ADHD would have better outcomes, compared to children matched for hyperactivity/inattention behaviors who were left undiagnosed and untreated, but we were surprised to find that, at best, outcomes were unchanged, and for some outcomes, worse,” Dr. Barratt said.

“Our study provides evidence that diagnosing ADHD may lead, inadvertently, to long-term harms, particularly for children with mild or borderline hyperactivity and inattention behaviors,” she emphasized.

“We can’t say from this study what to do instead, but previously one of our team has looked at stepped diagnosis as an alternative option for children with mild or borderline hyperactivity and inattention behaviors,” she said.

The stepped diagnosis includes such actions as gathering behavior data from multiple sources, and conducting a period of watchful waiting without presumption of a diagnosis or active treatment.

Given the findings of the new study, “I would ask that health professionals considering a child who may have ADHD be aware that there is an evidence gap around the long-term impact of an ADHD diagnosis on children, and to proceed cautiously,” Dr. Barratt said. As for additional research, independent, high-quality, randomized controlled trials of ADHD diagnosis in children with mild or borderline hyperactivity/inattention behaviors are urgently needed, with long-term, patient-centered outcomes including quality of life she noted.

ADHD screening needs improvement

The incidence and prevalence of ADHD is on the rise, but much of the perceived increase in ADHD may be due to overdiagnosis, “and a lack of robust thorough psychological testing as standard of care for diagnosis,” Peter Loper, MD, a pediatrician and psychiatrist at the University of South Carolina, Columbia, said in an interview.

The current study “reinforces the necessity of consistent screening for comorbid mental health problems, and specifically for thoughts of self-harm, in those children who are diagnosed with ADHD,” he said.

Expressing his lack of astonishment about the study findings, Dr. Loper said: “Previous data indicates that while following initial diagnosis of a medical or mental health problem, patients may experience a sense of relief; however, this is followed shortly thereafter by feelings of insufficiency or anxiety related to their specific diagnosis.”

“As it stands now, ADHD is often diagnosed in children and adolescents using basic screening questionnaires,” said Dr. Loper. “The findings of this study may bolster calls for more robust and thorough psychological testing for supporting the diagnosis of ADHD,” he said.

Individuals diagnosed with ADHD can sometimes have difficulty with social skills and relating to others, said Dr. Loper. “They may be more prone to internalize their poor school performance as due to being ‘stupid’ or ‘dumb,’ ” he said. Children and teens with ADHD should, whenever possible, be involved in extracurricular activities that support the development of social skills, he said. Parents’ praise of the process/effort, rather than focusing only on outcomes such as grades, is very important for the esteem of children and teens with ADHD, he added.

The study limitations included the use of observational data vs. data from randomized trials, and the potential for confounding factors in propensity scoring, the researchers wrote. Additional limitations include the size of the sample, which may have been too small to detect additional differences between diagnosed teens and matched controls, they noted.

“As the study authors appropriately cite, a large, randomized trial would be very helpful in supporting additional understanding of this issue,” Dr. Loper added.

The study was supported by the National Health and Medical Research Council The researchers and Dr. Loper had no financial conflicts to disclose.

Use of a sepsis predictor made little difference in time to antibiotic administration for septic patients in the emergency department, based on data from more than 200 patients.

“One of the big problems with sepsis is the lack of current tools for early and accurate diagnoses,” said Daniel Burgin, MD, an internal medicine resident at Louisiana State University, Baton Rouge, in a presentation at the annual meeting of the American College of Chest Physicians.

The EPIC Sepsis Model (ESM) was designed to help facilitate earlier detection of sepsis and speed time to the start of antibiotics, but its effectiveness has not been well studied, Dr. Burgin said.

In Dr. Burgin’s facility, the ESM is mainly driven by systemic inflammatory response syndrome (SIRS) and blood pressure and is calculated every 15 minutes; the system triggers a best-practice advisory if needed, with an alert that sepsis may be suspected.

To assess the impact of ESM on time to antibiotics, Dr. Burgin and colleagues reviewed data from 226 adult patients who presented to a single emergency department between February 2019 and June 2019. All patients presented with at least two criteria for SIRS. An ESM threshold of 6 was designed to trigger a set of orders to guide providers on a treatment plan that included antibiotics.

The researchers compared times to the ordering and the administration of antibiotics for patients with ESM scores of 6 or higher vs. less than 6 within 6 hours of triage in the ED. A total of 109 patients (48.2%) received antibiotics in the ED. Of these, 71 (74.5%) had ESM less than 6 and 38 (40.6%) had ESM of 6 or higher. The times from triage to antibiotics ordered and administered was significantly less in patients with ESM of 6 or higher (90.5 minutes vs. 131.5 minutes; 136 minutes vs. 186 minutes, respectively; P = .011 for both).

A total of 188 patients were evaluated for infection, and 86 met Sepsis-2 criteria based on physician chart review. These patients were significantly more likely than those not meeting the Sepsis-2 criteria to receive antibiotics in the ED (76.7% vs. 22.8%; P <.001).

Another 21 patients met criteria for Sepsis-3 based on a physician panel. Although all 21 received antibiotics, 5 did not receive them within 6 hours of triage in the ED, Dr. Burgin said. The median times to ordering and administration of antibiotics for Sepsis-3 patients with an ESM of 6 or higher were –5 and 38.5 (interquartile range), respectively.

“We hope that the ESM would prompt providers to start the order [for antibiotics],” Dr. Burgin said in his presentation. However, the researchers found no consistent patterns, and in many cases the ESM alerts occurred after the orders had been initiated, he noted.

The study findings were limited by the use of data from a single center; the implementation of the EPIC tool is hospital specific, said Dr. Burgin. However, the results suggest that “the ESM trigger is not improving the time to ordering of antibiotics for septic patients, and we question the utility of this tool in its current state,” he said.

“While this research proved useful in assessing the impact of ESM on time to antibiotics, more research is needed to understand how to operationalize predictive analytics,” Dr. Burgin said of the study findings. “The goal is to find the balance between early identification of sepsis and timely antimicrobial therapy and the potential harm of overalerting treatment teams.”

The study was supported in part by Cytovale, a sepsis diagnostics company. Several coauthors disclosed financial relationships with Cytovale. Dr. Burgin reports no relevant financial relationships.

Workers in the hard rock and other mining industries were significantly more likely to develop rheumatoid arthritis than were controls in the general population, based on data from nearly 2,000 individuals.

Although respirable silica exposure has been consistently linked to rheumatoid arthritis (RA) in a variety of occupations including foundry work, construction, and stone crushing and drilling, the association between RA risk and hard rock mining has not been investigated, lead author Paul D. Blanc, MD, of the University of California, San Francisco, and colleagues wrote in a study published in JAMA Network Open.

“Many clinical rheumatologists and most generalists are unaware that what a person does for a living can be a risk factor for rheumatoid arthritis,” Dr. Blanc said in an interview. “This study makes an important contribution to showing that work exposures can more than double the risk of RA,” he said.

“We were surprised by the widespread nature of the work-related risk within and beyond the mining sector,” Dr. Blanc noted. Given the range of potential occupational exposures, his take-home message to rheumatologists is to ask each and every patient about their work history.

The researchers conducted random telephone surveys of 1,988 men aged 50 years and older living in the Four Corners region of the United States (Colorado, New Mexico, and Utah) in counties selected for high levels of pneumoconiosis mortality. The surveys were conducted between Jan. 12, 2021, and May 4, 2021. The mean age of the study population was 68.6 years, and 82.6% were non-Hispanic White. Approximately half reported being former or current smokers.

RA was defined as having a clinician diagnosis, and was further defined by treatment with corticosteroids or disease-modifying antirheumatic drugs (DMARDs).

A total of 262 respondents (13.1%) reported work in surface mining or ore processing, with no underground exposure; 118 respondents (5.9%) reported work in underground hard rock mining; and 62 (3.1%) reported work in underground mining of other type, primarily coal mining.

Overall, after adjusting for age, smoking, and nonmining silica exposure, any mining work was associated with a three- to fourfold increased risk of RA for individuals with a RA diagnosis who were treated with corticosteroids and those treated with DMARDs (odds ratios, 4.12 and 3.30, respectively).

The risk was approximately nine times and six times higher for individuals with a history of underground soft rock mining (mainly coal, no hard rock mining), with odds ratios of 9.74 and 6.42, for those with RA treated with corticosteroids and DMARDs, respectively.

The odds of RA were higher with coal and other underground fossil hydrocarbon mining, compared with underground hard rock mining, the researchers wrote in their discussion. Reasons for this difference could include the longer employment duration for underground coal mining, but also the possibility that “in coal mining, silica inhalation may not be the sole cause, but rather that carbonaceous materials may also be involved etiologically in RA risk in that occupation,” they wrote. No association was found between increased risk of RA and current or former smoking, they noted, in contrast to the researchers’ previous studies of Appalachian coal miners.

The study findings were limited by several factors including the potential for recall bias and misclassified exposure and diagnoses, the researchers noted. Other limitations include the focus on individuals aged 50 years and older in a limited geographic region of the United States and the relatively short time of employment in mining, they said.

However, the results support previous studies showing an increased RA risk with respirable silica exposure, and suggest that clinicians consider mining among other work exposures that could increase the risk for developing RA, the researchers concluded.

Looking ahead, Dr. Blanc said that additional research is needed to tease out disease progression and severity in the face of past occupational exposures.

The study was supported by the Alpha Foundation and the Russell/Engleman Rheumatology Research Center through grants to the researchers. The researchers had no other financial conflicts to disclose.

Workers in the hard rock and other mining industries were significantly more likely to develop rheumatoid arthritis than were controls in the general population, based on data from nearly 2,000 individuals.

Although respirable silica exposure has been consistently linked to rheumatoid arthritis (RA) in a variety of occupations including foundry work, construction, and stone crushing and drilling, the association between RA risk and hard rock mining has not been investigated, lead author Paul D. Blanc, MD, of the University of California, San Francisco, and colleagues wrote in a study published in JAMA Network Open.

“Many clinical rheumatologists and most generalists are unaware that what a person does for a living can be a risk factor for rheumatoid arthritis,” Dr. Blanc said in an interview. “This study makes an important contribution to showing that work exposures can more than double the risk of RA,” he said.

“We were surprised by the widespread nature of the work-related risk within and beyond the mining sector,” Dr. Blanc noted. Given the range of potential occupational exposures, his take-home message to rheumatologists is to ask each and every patient about their work history.

The researchers conducted random telephone surveys of 1,988 men aged 50 years and older living in the Four Corners region of the United States (Colorado, New Mexico, and Utah) in counties selected for high levels of pneumoconiosis mortality. The surveys were conducted between Jan. 12, 2021, and May 4, 2021. The mean age of the study population was 68.6 years, and 82.6% were non-Hispanic White. Approximately half reported being former or current smokers.

RA was defined as having a clinician diagnosis, and was further defined by treatment with corticosteroids or disease-modifying antirheumatic drugs (DMARDs).

Home-based transcranial direct current stimulation with real-time supervision significantly improved clinical symptoms of major depressive disorder, based on data from 26 individuals.

Major depressive disorder (MDD) remains a leading cause of disability and a significant predictor of suicide worldwide, Rachel D. Woodham, PhD, of the University of East London and colleagues wrote.

Transcranial direct current stimulation (tDCS) has demonstrated effectiveness as a noninvasive therapy for MDD, but requires frequent sessions, and repeat visits to treatment centers are a barrier for many patients, they noted. The tDCS procedure involves delivery of a weak direct electric current via placement of electrodes, usually with the anode over the left dorsolateral prefrontal cortex and the cathode over the right dorsolateral prefrontal cortex, suborbital, or frontotemporal region.

“The current changes neuronal membrane potential and facilitates discharge,” but “in contrast to rTMS and ECT, tDCS does not directly trigger an action potential,” the researchers wrote. The most common side effects reported with tDCS are tingling, itching, burning sensation, skin redness or headache.

The researchers proposed that tDCS could be provided at home under real-time remote supervision.

In an open-label feasibility study published in the Journal of Psychiatric Research, they recruited 26 adults with MDD in current depressive episodes of moderate to severe severity. In addition to maintaining their current treatment regimens of medication, psychotherapy, or cognitive behavioral therapy, participants used tDCS at home in 30-minute sessions, for a total of 21 sessions over 6 weeks. A researcher was present in person or on a real-time video call for each at-home session.

The primary outcome of Hamilton Rating Scale for Depression (HAMD) score improved significantly, from a mean of 19.12 at baseline to 5.33 after 6 weeks. At 3 months, the mean HAMD score was 5.65, and 78.2% of patients met the criteria for clinical remission (HAMD score less than 9). At 6 months, patients maintained this improvement, with a mean HAMD score of 5.43 and 73.9% of the participants in clinical remission. The majority of participants (24 of 26) completed the full 6-week treatment.

Clinical assessments were conducted at baseline, at the end of the 6-week treatment period, at 3 months, and at 6 months, and included not only the HAMD, but also the Hamilton Anxiety Rating Scale (HAMA), Sheehan Disability Scale (SDS), Patient Health Questionnaire–9 (PHQ-9), and Young Mania Rating Scale. All participants showed significant improvements in HAMA, SDS, and PHQ-9 scores from baseline that endured from the end of the treatment period to the 6 months’ follow-up.

The tDCS involved a bilateral frontal montage, F3 anode, F4 cathode, 2mA, and two different devices were used.

All participants reported the acceptability of at-home tDCS as either “very acceptable” or “quite acceptable.”

The results were limited by the open-label feasibility design and lack of a sham control treatment; therefore, the findings of efficacy are preliminary, the researchers emphasized. “Having real-time supervision for each session likely contributed to symptom improvement.”

However, the results support the feasibility of at-home tDCS to improve outcomes both short- and long-term in patients with moderate to severe MDD, the researchers said. Larger, sham-controlled trials are needed to show efficacy, and additional assessment of feasibility should include the use of app-based devices, which may be more feasible for individuals with lower socioeconomic status.

The study received no outside funding. The study was supported by the Rosetrees Trust. The researchers had no financial conflicts to disclose.

Individuals who experience out-of-hospital cardiac arrest (OHCA) with nonshockable presentations have a better chance of survival when first responders use a novel CPR approach that includes gradual head-up positioning combined with basic but effective circulation-enhancing adjuncts, as shown from data from more than 2,000 patients.

In a study presented at the annual meeting of the American College of Emergency Physicians, Paul Pepe, MD, medical director for Dallas County Emergency Medical Services, reviewed data from five EMS systems that had adopted the new approach. Data were collected prospectively over the past 2 years from a national registry of patients who had received what Dr. Pepe called a “neuroprotective CPR bundle” (NP-CPR).

The study compared 380 NP-CPR case patients to 1,852 control patients who had received conventional CPR. Control data came from high-performance EMS systems that had participated in well-monitored, published OHCA trials funded by the National Institutes of Health. The primary outcome that was used for comparison was successful survival to hospital discharge with neurologically intact status (SURV-NI).

Traditional CPR supine chest compression techniques, if performed early and properly, can be lifesaving, but they are suboptimal, Dr. Pepe said. “Current techniques create pressure waves that run up the arterial side, but they also create back-pressure on the venous side, increasing intracranial pressure (ICP), thus compromising optimal cerebral blood flow,” he told this news organization.

For that reason, a modified physiologic approach to CPR was designed. It involves an airway adjunct called an impedance threshold device (ITD) and active compression-decompression (ACD) with a device “resembling a toilet plunger,” Dr. Pepe said.

The devices draw more blood out of the brain and into the thorax in a complementary fashion. The combination of these two adjuncts had dramatically improved SURV-NI by 50% in a clinical trial, Dr. Pepe said.

The new technology uses automated gradual head-up/torso-up positioning (AHUP) after first “priming the pump” with ITD-ACD–enhanced circulation. It was found to markedly augment that effect even further. In the laboratory setting, this synergistic NP-CPR bundle has been shown to help normalize cerebral perfusion pressure, further promoting neuro-intact survival. Normalization of end-tidal CO2 is routinely observed, according to Dr. Pepe.

In contrast to patients who present with ventricular fibrillation (shockable cases), patients with nonshockable presentations always have had grim prognoses, Dr. Pepe said. Until now, lifesaving advances had not been found, despite the fact that nonshockable presentations (asystole or electrical activity with no pulse) constitute approximately 80% of OHCA cases, or about 250,000 to 300,00 cases a year in the United States, he said.

In the study, approximately 60% of both the NP-CPR patients and control patients had asystole (flatline) presentations. The NP-CPR group had a significant threefold improvement in SURV-NI, compared with patients treated with conventional CPR in the high-functioning systems (odds ratio, 3.09). In a propensity-scored analysis matching all variables known to affect outcome, the OR increased to nearly fourfold higher (OR, 3.87; 95% confidence interval, 1.27-11.78), Dr. Pepe said.

The researchers also found that the time from receipt of a 911 call to initiation of AHUP was associated with progressively higher chances of survival. The median time for application was 11 minutes; when the elapsed time was less than 11 minutes, the SURV-NI was nearly 11-fold higher for NP-CPR patients than for control patients (OR, 10.59), with survival chances of 6% versus 0.5%. ORs were even higher when the time to treatment was less than 16 minutes (OR, 13.58), with survival rates of 5% versus 0.4%.

The findings not only demonstrate proof of concept in these most futile cases but also that implementation is feasible for the majority of patients, considering that the median time to the start of any CPR by a first responder was 8 minutes for both NP-CPR patients and control patients, “let alone 11 minutes for the AHUP initiation,” Dr. Pepe said. “This finally gives some hope for these nonshockable cases,” he emphasized.

“All of these devices have now been cleared by the Food and Drug Administration and should be adopted by all first-in responders,” said Dr. Pepe. “But they should be implemented as a bundle and in the proper sequence and as soon as feasible.”

Training and implementation efforts continue to expand, and more lives can be saved as more firefighters and first-in response teams acquire equipment and training, which can cut the time to response, he said.

The registry will continue to monitor outcomes with NP-CPR – the term was suggested by a patient who survived through this new approach – and Dr. Pepe and colleagues expect the statistics to improve further with wider adoption and faster implementation with the fastest responders.

A recent study by Dr. Pepe’s team, published in Resuscitation, showed the effectiveness of the neuroprotective bundle in improving survival for OHCA patients overall. The current study confirmed its impact on neuro-intact survival for the subgroup of patients with nonshockable cases.

One other take-home message is that head-up CPR cannot yet be performed by lay bystanders. “Also, do not implement this unless you are going to do it right,” Dr. Pepe emphasized in an interview.

ORs were even higher when the time to treatment was less than 16 minutes (OR, 13.58), with survival rates of 5% versus 0.4%.

The findings not only demonstrate proof of concept in these most futile cases but also that implementation is feasible for the majority of patients, considering that the median time to the start of any CPR by a first responder was 8 minutes for both NP-CPR patients and control patients, “let alone 11 minutes for the AHUP initiation,” Dr. Pepe said. “This finally gives some hope for these nonshockable cases,” he emphasized.

“All of these devices have now been cleared by the Food and Drug Administration and should be adopted by all first-in responders,” said Dr. Pepe. “But they should be implemented as a bundle and in the proper sequence and as soon as feasible.”

Training and implementation efforts continue to expand, and more lives can be saved as more firefighters and first-in response teams acquire equipment and training, which can cut the time to response, he said.

The registry will continue to monitor outcomes with NP-CPR – the term was suggested by a patient who survived through this new approach – and Dr. Pepe and colleagues expect the statistics to improve further with wider adoption and faster implementation with the fastest responders.

A recent study by Dr. Pepe’s team, published in Resuscitation, showed the effectiveness of the neuroprotective bundle in improving survival for OHCA patients overall. The current study confirmed its impact on neuro-intact survival for the subgroup of patients with nonshockable cases.

One other take-home message is that head-up CPR cannot yet be performed by lay bystanders. “Also, do not implement this unless you are going to do it right,” Dr. Pepe emphasized in an interview.

Full vaccination status against COVID-19 was associated with significantly reduced mortality among critically ill patients with COVID-19 who needed mechanical ventilation, according to results of a study that involved 265 adults.

Although COVID-19 vaccination has been demonstrated to be effective at preventing infection, breakthrough infections occur, write Eirini Grapsa, RN, of Kapodistrian University of Athens Medical School, Greece, and colleagues. The potential protective benefits of vaccination for patients who experience these breakthrough infections, especially cases severe enough to require hospitalization and the need for mechanical ventilation, have not been well studied, the investigators say.

In a study published in JAMA Network Open, the researchers reviewed data from 265 consecutive patients older than 18 years who were admitted to intensive care units at three tertiary care centers with confirmed SARS-CoV-2 infections between June 7, 2021, and Feb. 1, 2022. All patients in the study received invasive mechanical ventilation because of acute respiratory distress syndrome (ARDS). The patients were divided into two groups: 26 patients were in the full vaccination group, and 239 served as control patients. Full vaccination was defined as having completed the primary COVID-19 series more than 14 days but less than 5 months before intubation. The control group included patients who had been fully vaccinated for less than 14 days or more than 5 months, were partially vaccinated, or were not vaccinated. A total of 20 of 26 patients in the full vaccination group received the Pfizer BioNTech BNT162b2 vaccine, as did 25 of the 33 vaccinated patients in the control group.

The median age of the patients overall was 66 years; 36% were women, and 99% were White. Patients in the full vaccination group were more likely to be older and to have comorbidities. The primary outcome was the time from intubation to all-cause mortality.

Overall, mortality was lower among the patients with full vaccination status than among those in the control group (61.5% vs. 68.2%; P = .03). Full vaccination also was associated with lower mortality in sensitivity analyses that included (a) only patients who received an mRNA vaccine in the full vaccination group, and (b) only unvaccinated patients in the control group (hazard ratios, 0.47 and 0.54, respectively).

In a regression model that examined secondary outcomes, the HR was 0.40 for the association between full vaccination and 28-day mortality. No significant differences were seen in length of stay in the intensive care unit (ICU) or length of hospital stay among survivors, nor in the occurrence of bacteremia, use of vasopressors, number of vasopressor-free days, use of continuous kidney replacement therapy (CKRT), number of CKRT-free days, and the number of ventilator-free and ICU-free days.

“Our choice to take time since vaccination into consideration was based on several previous studies indicating that protection against infection from vaccination (specifically with mRNA vaccines, such as BNT162b2, which was administered to 76.9% of patients in the full vaccination group) may decrease over time,” the researchers write.

Oxygenation was higher in the full vaccination group than in the control group on the third day after intubation. Previous studies conducted before the COVID-19 pandemic have shown that oxygenation on the third day after intubation may be more strongly associated with mortality than oxygenation on the day of intubation, the researchers note. Bacteremia was higher among the control patients and could have affected mortality, although the difference between vaccinated patients and control patients was not significant, the researchers add.

The study findings were limited by several factors, including small sample size, which prevented direct comparisons of the effectiveness of different numbers of vaccine doses or vaccine types, the researchers note. Other limitations include selection bias and residual confounding variables, they say.

The results demonstrate an association between full vaccination and lower mortality and suggest that vaccination may benefit patients with COVID-19–related ARDS, beyond the need for mechanical ventilation alone, they say. “These results expand our understanding of the outcomes of patients with breakthrough infections,” they conclude.

The study was supported by a grant to corresponding author Ilias I. Siempos, MD, from the Hellenic Foundation for Research and Innovation. The researchers have disclosed no relevant financial relationships.
