Approximately one-third of individuals with autism spectrum disorder (ASD) are prescribed multiple medications to manage comorbidities and symptoms, according to data from a retrospective cohort study of more than 26,000 patients.

“Clinicians caring for patients with ASD are tasked with the challenges of managing the primary disease, as well as co-occurring medical conditions, and coordinating with educational and social service professionals to provide holistic care,” wrote Aliya G. Feroe of Harvard Medical School, Boston, and colleagues.

The medication classes used to treat individuals with ASD include ADHD medications, antipsychotics, antidepressants, mood stabilizers, benzodiazepines, anxiolytics, and hypnotics, but the prescription rates of these medications in ASD patients have not been examined in large studies, the researchers said.

In a study published in JAMA Pediatrics, the researchers identified 26,722 individuals with ASD using a United States health care database from Jan. 1, 2014, to Dec. 31, 2019. Data included records of inpatient and outpatient claims, and records of prescriptions filled through commercial pharmacies. Individuals received at least 1 of 24 of the most common medication groups for ASD or comorbidities. The average age of the study participants was 14 years, and 78% were male. Diagnostic codes for ASD were based on the International Classification of Diseases, Ninth Revision, and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision.

Over the 6-year study period, approximately one-third of the participants were taking three or more medications at once, ranging from 28.6% to 31.5%. In any 1 year, approximately 41% of children were prescribed a single medication, 17% received two prescriptions, 7.9% received four, and 3.4% received five. Medication changes occurred more frequently within classes than between classes, and reasons for these changes may include patient preference, adverse effects, and cost, the researchers noted.

The overall number of children prescribed particular drugs remained consistent, the researchers noted. “For example, the total number of individuals prescribed methylphenidate shifted from 832 in 2014 to 850 in 2015, 899 in 2016, 863 in 2017, and 838 in 2018,” they wrote.

In 15 of the 24 medication groups included in the study, at least 15% of the individuals had unspecified anxiety disorder, anxiety neurosis, or major depressive disorder; in 11 of the medication groups, at least 15% had some form of ADHD. ADHD prevalence in patients taking stimulants varied based on ADHD type, the researchers said.

The most common comorbidities in patients taking antipsychotics were combined type ADHD (11.6%-17.8%) and anxiety disorder (13.1%-30.1%). The study findings suggest that many clinicians are incorporating medications into ASD management, the researchers said.

“Although there is no medical treatment for the core deficits of social communication and repetitive behavioral patterns in ASD, the American Academy of Pediatrics recommends that clinicians consider medications in the management of common comorbid conditions, including seizures, ADHD, anxiety disorders, mood disorders, and disruptive behavior disorders,” they said.

The findings were limited by several factors including the potential for inconsistent reporting of diagnoses and pharmacy claims, the researchers noted. Other limitations included a lack of direct clinical assessment to validate diagnoses and the absence of validated diagnostic instruments to screen for comorbidities, they added.

“Our findings suggest that clinicians may be increasingly using integrated approaches to treating patients with ASD and co-occurring conditions, and further work is necessary to determine the relative effects of pharmacotherapy vs. behavioral interventions on outcomes in patients with ASD,” the researchers concluded.
 

Many reasons for multiple medications

“The researchers put in a lot of effort to provide data on a large scale,” Herschel Lessin, MD, of Children’s Medical Group, Poughkeepsie, N.Y., said in an interview.

“The findings illustrate the reality that autistic children are prescribed a lot of medications for a lot of reasons, some of which are not entirely clear,” Dr. Lessin said. The study also reflects the chronic lack of behavioral health services for children, he noted. Many children with ASD are referred for services they are unable to access, he said. “As a result, they see doctors who can only prescribe medications to try to control behavior or symptoms for which the cause is unclear,” and which could be ASD or other comorbidities, he emphasized.

The large sample size strengthens the study findings, but some of the challenges include the use of claims data, which do not indicate how diagnoses were made, said Dr. Lessin. An additional limitation is the fact that many medications for children with autism are used off label, so the specific reason for their use may be unknown, he said.

The take-home message for clinicians is that children with ASD are getting a lot of medications, and pediatricians are not usually responsible for multiple medications,” Dr. Lessin said. Ultimately, the study is “a plea for more research,” to tease out details of what medications are indicated and helpful, he said.

The study received no outside funding. The researchers and Dr. Lessin had no financial conflicts to disclose. Dr. Lessin serves on the Pediatric News editorial advisory board.

Low adenoma detection rates (ADRs) were associated with a greater risk of death in colorectal cancer (CRC) patients, especially among those with high-risk adenomas, based on a review of more than 250,000 colonoscopies.

“Both performance quality of the endoscopist as well as specific characteristics of resected adenomas at colonoscopy are associated with colorectal cancer mortality,” but the impact of these combined factors on colorectal cancer mortality has not been examined on a large scale, according to Elisabeth A. Waldmann, MD, of the Medical University of Vienna and colleagues.

In a study published in Clinical Gastroenterology & Hepatology, the researchers reviewed 259,885 colonoscopies performed by 361 endoscopists. Over an average follow-up period of 59 months, 165 CRC-related deaths occurred.

Across all risk groups, CRC mortality was higher among patients whose colonoscopies yielded an ADR of less than 25%, although this was not statistically significant in all groups.

The researchers then stratified patients into those with a negative colonoscopy, those with low-risk adenomas (one to two adenomas less than 10 mm), and those with high-risk adenomas (advanced adenomas or at least three adenomas), with the negative colonoscopy group used as the reference group for comparisons. The average age of the patients was 61 years, and approximately half were women.

Endoscopists were classified as having an ADR of less than 25% or 25% and higher.

Among individuals with low-risk adenomas, CRC mortality was similar whether the ADR on a negative colonoscopy was less than 25% or 25% or higher (adjusted hazard ratios, 1.25 and 1.22, respectively). CRC mortality also remained unaffected by ADR in patients with negatively colonoscopies (aHR, 1.27).

By contrast, individuals with high-risk adenomas had a significantly increased risk of CRC death if their colonoscopy was performed by an endoscopist with an ADR of less than 25%, compared with those whose endoscopists had ADRs of 25% or higher (aHR, 2.25 and 1.35, respectively).

“Our study demonstrated that adding ADR to the risk stratification model improved risk assessment in all risk groups,” the researchers noted. “Importantly, stratification improved most for individuals with high-risk adenomas, the group demanding most resources in health care systems.”

The study findings were limited by several factors including the focus on only screening and surveillance colonoscopies, not including diagnostic colonoscopies, and the inability to adjust for comorbidities and lifestyle factors that might impact CRC mortality, the researchers noted. The 22.4% average ADR in the current study was low, compared with other studies, and could be a limitation as well, although previous guidelines recommend a target ADR of at least 20%.

“Despite the extensive body of literature supporting the importance of ADR in terms of CRC prevention, its implementation into clinical surveillance is challenging,” as physicians under pressure might try to game their ADRs, the researchers wrote.

The findings support the value of mandatory assessment of performance quality, the researchers added. However, “because of the potential possibility of gaming one’s ADR one conclusion drawn by the study results should be that endoscopists’ quality parameters should be monitored and those not meeting the standards trained to improve rather than requiring minimum ADRs as premise for offering screening colonoscopy.”
 

Improve performance, but don’t discount patient factors

The study is important at this time because colorectal cancer is the third-leading cause of cancer death in the United States, Atsushi Sakuraba, MD, of the University of Chicago said in an interview.

“Screening colonoscopy has been shown to decrease CRC mortality, but factors influencing outcomes after screening colonoscopies remain to be determined,” he said.

“It was expected that high-quality colonoscopy performed by an endoscopist with ADR of 25% or greater was associated with a lower risk for CRC death,” Dr. Sakuraba said. “The strength of the study is that the authors demonstrated that high-quality colonoscopy was more important in individuals with high-risk adenomas, such as advanced adenomas or at least three adenomas.”

The study findings have implications for practice in that they show the importance of monitoring performance quality in screening colonoscopy, Dr. Sakuraba said, “especially when patients have high-risk adenomas.” However, “the authors included only age and sex as variables, but the influence of other factors, such as smoking, [body mass index], and race, need to be studied.”

The researchers had no financial conflicts to disclose. Dr. Sakuraba had no financial conflicts to disclose.

About one-third of individuals with adult-onset idiopathic dystonia experience major depression or dysthymia, data from a meta-analysis of 54 studies show.

Adult-onset idiopathic dystonia (AOID) is the third-most common movement disorder after essential tremor and Parkinson’s disease, and data show that depression and anxiety are the largest contributors to reduced quality of life in these patients, wrote Alex Medina Escobar, MD, of the University of Calgary (Alta.), and colleagues. However, “the pathogenic mechanisms of depression and anxiety in AOID remain unclear” and might involve a combination of biologic factors, as well as social stigma.

In the meta-analysis, published in Neuroscience and Biobehavioral Reviews, the researchers examined the point prevalence of supraclinical threshold depressive symptoms/depressive disorders in AOID using 54 studies. The resulting study population included 12,635 patients: 6,977 with cervical dystonia, 732 with cranial dystonia, 4,504 with mixed forms, 303 with laryngeal dystonia, and 119 with upper-limb dystonia. The studies were published between 1988 and 2020, and included patients from 21 countries in 52 single-center studies and 2 multicenter studies.

Overall, the pooled prevalence of either supraclinical threshold depressive symptoms or depressive disorders was 31.5% for cervical dystonia, 29.2 % for cranial dystonia, and 33.6 % for clinical samples with mixed forms of AOID.

Among patients with cervical dystonia, major depressive disorder was more prevalent than dysthymia, but among patients with cranial dystonia, dysthymia was more prevalent. Among patients with mixed forms, the prevalence of major depressive disorder was higher than dysthymia. Heterogeneity varied among the studies but was higher in studies that used rating scales.

Treatment of patients with AOID does not take into account the impact of depression on quality of life, Dr. Escobar and colleagues reported.

“The current model of care for AOID remains primarily centered on the treatment of the movement disorder with local injections of botulinum toxin. Such model appears to be inefficient to guarantee resources to address these comorbidities within secondary or tertiary care, or through shared care pathways engaging both primary and hospital-based care.” They also said the use of antidepressants and cognitive-behavioral therapy as a way to target negative body concept or social stigma among these patients are “underexplored and underutilized.”

The study findings were limited by several factors, including the inclusion only of studies published in English. In addition, most of the studies were conducted at movement disorders clinics, which may have yielded a patient population with more severe AOID. Further limitations included the inability to perform subgroup analysis based on demographic and clinical factors, and the insufficient number of studies for meta-analysis of laryngeal and hand dystonia, Dr. Escobar and colleagues added.

However, the results represent the first pooled estimate of depression prevalence in AOID and confirm a high prevalence across different clinical forms, the researchers said. The heterogeneity across studies highlights the need for standardized screening for depression and improved diagnosis of mood disorders in AOID.

“The meta-analytic estimates provided here will be highly useful for the planning of future mechanistic and interventional studies, as well as for the redefinition of current models of care,” they concluded.

The study received no outside funding. Dr. Escobar and colleagues had no disclosures.

Further limitations included the inability to perform subgroup analysis based on demographic and clinical factors, and the insufficient number of studies for meta-analysis of laryngeal and hand dystonia, Dr. Escobar and colleagues added.

However, the results represent the first pooled estimate of depression prevalence in AOID and confirm a high prevalence across different clinical forms, the researchers said. The heterogeneity across studies highlights the need for standardized screening for depression and improved diagnosis of mood disorders in AOID.

“The meta-analytic estimates provided here will be highly useful for the planning of future mechanistic and interventional studies, as well as for the redefinition of current models of care,” they concluded.

The study received no outside funding. Dr. Escobar and colleagues had no disclosures.

About one-third of individuals with adult-onset idiopathic dystonia experience major depression or dysthymia, data from a meta-analysis of 54 studies show.

Adult-onset idiopathic dystonia (AOID) is the third-most common movement disorder after essential tremor and Parkinson’s disease, and data show that depression and anxiety are the largest contributors to reduced quality of life in these patients, wrote Alex Medina Escobar, MD, of the University of Calgary (Alta.), and colleagues. However, “the pathogenic mechanisms of depression and anxiety in AOID remain unclear” and might involve a combination of biologic factors, as well as social stigma.

In the meta-analysis, published in Neuroscience and Biobehavioral Reviews, the researchers examined the point prevalence of supraclinical threshold depressive symptoms/depressive disorders in AOID using 54 studies. The resulting study population included 12,635 patients: 6,977 with cervical dystonia, 732 with cranial dystonia, 4,504 with mixed forms, 303 with laryngeal dystonia, and 119 with upper-limb dystonia. The studies were published between 1988 and 2020, and included patients from 21 countries in 52 single-center studies and 2 multicenter studies.

Overall, the pooled prevalence of either supraclinical threshold depressive symptoms or depressive disorders was 31.5% for cervical dystonia, 29.2 % for cranial dystonia, and 33.6 % for clinical samples with mixed forms of AOID.

Among patients with cervical dystonia, major depressive disorder was more prevalent than dysthymia, but among patients with cranial dystonia, dysthymia was more prevalent. Among patients with mixed forms, the prevalence of major depressive disorder was higher than dysthymia. Heterogeneity varied among the studies but was higher in studies that used rating scales.

Treatment of patients with AOID does not take into account the impact of depression on quality of life, Dr. Escobar and colleagues reported.

“The current model of care for AOID remains primarily centered on the treatment of the movement disorder with local injections of botulinum toxin. Such model appears to be inefficient to guarantee resources to address these comorbidities within secondary or tertiary care, or through shared care pathways engaging both primary and hospital-based care.” They also said the use of antidepressants and cognitive-behavioral therapy as a way to target negative body concept or social stigma among these patients are “underexplored and underutilized.”

The study findings were limited by several factors, including the inclusion only of studies published in English. In addition, most of the studies were conducted at movement disorders clinics, which may have yielded a patient population with more severe AOID.

Schizophrenia patients with parkinsonism show distinctive patterns of cortical surface markers, compared with schizophrenia patients without parkinsonism and healthy controls, results of a multimodal magnetic resonance imaging study suggest.

Sensorimotor abnormalities are common in schizophrenia patients, however, “the neurobiological mechanisms underlying parkinsonism in [schizophrenia], which in treated samples represents the unity of interplay between spontaneous and antipsychotic drug-exacerbated movement disorder, are poorly understood,” wrote Robert Christian Wolf, MD, of Heidelberg (Germany) University, and colleagues.

In a study published in Schizophrenia Research (2021 May;231:54-60), the investigators examined brain imaging findings from 20 healthy controls, 38 schizophrenia patients with parkinsonism (SZ-P), and 35 schizophrenia patients without parkinsonism (SZ-nonP). Dr. Wolf and colleagues examined three cortical surface markers: cortical thickness, complexity of cortical folding, and sulcus depth.

Compared with SZ-nonP patients, the SZ-P patients showed significantly increased complexity of cortical folding in the left supplementary motor cortex (SMC) and significantly decreased left postcentral sulcus (PCS) depth. In addition, left SMC activity was higher in both SZ-P and SZ-nonP patient groups, compared with controls.

In a regression analysis, the researchers examined relationships between parkinsonism severity and brain structure. They found that parkinsonism severity was negatively associated with left middle frontal complexity of cortical folding and left anterior cingulate cortex cortical thickness.

“Overall, the data support the notion that cortical features of distinct neurodevelopmental origin, particularly cortical folding indices such as [complexity of cortical folding] and sulcus depth, contribute to the pathogenesis of parkinsonism in SZ,” the researchers wrote.

The study findings were limited by several factors, including the cross-sectional design, the potential limitations of the Simpson-Angus Scale in characterizing parkinsonism, the inability to record lifetime antibiotics exposure in the patient population, and the inability to identify changes in brain stem nuclei, the researchers noted. However, the results were strengthened by the well-matched study groups and use of multimodal MRI, they said.

Consequently, “these data provide novel insights into different trajectories of cortical development in SZ patients evidencing parkinsonism,” and suggest a link between abnormal neurodevelopmental processes and an increased risk for movement disorders in schizophrenia, they concluded.

The study was funded by the German Research Foundation and the German Federal Ministry of Education and Research. Dr. Wolf and colleagues disclosed no conflicts.

Severe complications at 5 years were no different for patients with perforated purulent diverticulitis who underwent laparoscopic peritoneal lavage or colon resection, according to data from 199 individuals treated at 21 hospitals in Norway and Sweden. But it may yet prove appropriate in the right patient.

Acute perforated diverticulitis with peritonitis remains a challenging complication with high morbidity and mortality among patients with diverticular disease, and bowel resection remains the standard of treatment, Najia Azhar, MD, of Skåne University Hospital, Malmö, Sweden, and colleagues wrote.

Short-term data suggest that laparoscopic lavage with drainage and antibiotics might be a viable alternative, but long-term data are lacking, they said.

In the Scandinavian Diverticulitis (SCANDIV) trial, published in JAMA Surgery, researchers randomized 101 patients to laparoscopic peritoneal lavage and 98 to colon resection. With 3 patients lost to follow-up, the final analysis included 73 patients who underwent laparoscopic lavage and 69 who underwent resection. The mean age of the lavage patients was 66.4 years, and 39 were men. The mean age of the resection patients was 63.5 years, and 36 were men. The primary outcome was severe complications – excluding stoma reversals and elective sigmoid resections because of recurrence – at an average of 5 years’ follow-up. Secondary outcomes included stoma prevalence, diverticulitis recurrence, and secondary sigmoid resection.

Severe complications were similar for the lavage and resection groups (36% and 35%, respectively), as were the overall mortality rates (32% and 25%, respectively).

The prevalence of stoma was significantly lower in the lavage group, compared with the resection group (8% vs. 33%, P = .002). However, secondary operations (including reversal of stoma) were similar between the lavage and resection groups, performed in 26 lavage patients (36%) versus 24 resection patients (35%).

Diverticulitis recurrence was significantly more common in the lavage, compared with the resection group (21% vs. 4%, P = .004), the researchers noted.

In the laparoscopic lavage group, 30% (n = 21) underwent a sigmoid resection; all but one of these occurred within a year of the index procedure, the researchers wrote. In addition, overall length of hospital stay was similar for both groups.

No significant differences in quality of life were noted between the groups, based on the EuroQoL-5D questionnaire or Cleveland Global Quality of Life scores.
 

Balance secondary pros and cons

Laparoscopic lavage is not common practice today in the United States, the researchers noted. In clinical practice guidelines issued in 2020, the American Society of Colon and Rectal Surgeons strongly recommend colectomy over laparoscopic lavage for the treatment of left-sided colonic diverticulitis. However, the European Society of Coloproctology’s guidelines state that laparoscopic lavage is feasible for patients with peritonitis at Hinchey stage III.

The findings of the current study were limited primarily by the exclusion of 50% of eligible patients because of challenges associated with conducting randomized trials in emergency settings, the researchers noted. However, the number of excluded patients and their baseline characteristics after exclusion were very similar in the two groups, and the study represents the largest randomized trial to date to examine long-term outcomes in patients with perforated diverticulitis.

“Laparoscopic lavage is faster and cost-effective but leads to a higher reoperation rate and recurrence rate, often requiring secondary sigmoid resection,” the researchers emphasized. Consequently, patients undergoing lavage should have consented for resection surgery.

The similar rates of severe complications and quality of life scores support laparoscopic lavage as an option for perforated purulent diverticulitis, but shared decision-making will be essential for better optimal patient management, the researchers concluded.
 

Similar outcomes, but unanswered questions

Even though the primary outcome of disease-related morbidity was similar for both groups, “the issue still remains regarding when and how, if ever, this therapeutic approach should be considered for purulent peritonitis,” Kellie E. Cunningham, MD, and Brian S. Zuckerbraun, MD, both of the University of Pittsburgh, wrote in an accompanying editorial.

Although laparoscopic lavage has the obvious advantages of avoiding a laparotomy and stoma, previous studies have shown a higher rate of early reoperations and recurrent diverticulitis, despite lower stoma prevalence and equal mortality rates, they said. In addition, “patients who are immunosuppressed or would be expected to have a higher mortality rate with failure to achieve definitive source control should likely not be offered this therapy.”

A “philosophical” argument could be made in favor of laparoscopic lavage based on the potential consequences of early treatment failure, they wrote.

“Although one may consider the need for early reoperation a complication, some would argue it affects the minority of patients, thus avoiding the more morbid procedure with creation of a stoma at the index operation in the majority of patients,” they noted. “Additionally, patients who underwent lavage that subsequently proceed to colectomy would have otherwise been offered this therapy initially at the time of the index operation.”

More research is needed to answer questions such as which, if any, operative findings are associated with failure. In addition, an analysis of long-term cost benefits between the two options should be explored, the authors wrote.

Based on current evidence, shared decision-making is necessary, with individualized care and short and long-term trade-offs taken into account, they wrote.
 

Gastroenterologist perspective: Study fills gap in follow-up data

In an interview, David A. Johnson, MD, professor of medicine and chief of gastroenterology at Eastern Virginia School of Medicine, Norfolk, said the study is important because data have been lacking on outcomes of a laparoscopic lavage without a resection.

The findings represent “a major shift” in the growing consensus among surgeons that laparoscopic lavage is a viable option in appropriate patients, he said.

A key issue is the high rate of morbidity in patients who undergo traditional diverticulitis surgery. Complications can include wound infection and poor quality of life associated with stoma, Dr. Johnson said. Consequently, “a nonoperative approach from a patient perspective is certainly refreshing.”

Dr. Johnson said he was surprised by how well the patients fared after lavage given the severity of the diverticulitis in the patient population. However, this may be in part because of the relatively small numbers of patients at highest risk for complications, such as those with diabetes or immunocompromising conditions.

Dr. Johnson also said he was struck by the fact that the adenocarcinomas in the lavage group were diagnosed within the first year after the procedure. “The cancer diagnosis shouldn’t reflect on the lavage group,” but emphasizes the importance of having an earlier colonoscopy, he noted.

Next steps for research might include identifying a standardized endpoint for lavage, and determining how expanded use of the procedure might impact community practice, Dr. Johnson said. In addition, more research is needed to more clearly define patients most likely to benefit from laparoscopic lavage.

The study was supported in part by the department of surgery at Skåne University Hospital, Akershus University Hospital, and a fellowship to one of the study coauthors from the Southeastern Norway Regional Health Authority. Lead author Dr. Azhar disclosed grants from the department of surgery of Skåne University Hospital. Dr. Cunningham and Dr. Zuckerbraun had no financial conflicts to disclose.

Managing depression and anxiety in Parkinson’s disease should start with a review of medications and involve multidisciplinary care, according to a recent summary of evidence.

“Depression and anxiety have a complex relationship with the disease and while the exact mechanism for this association is unknown, both disturbances occur with increased prevalence across the disease course and when present earlier in life, increase the risk of PD by about twofold,” wrote Gregory M. Pontone, MD, of Johns Hopkins University, Baltimore, and colleagues.

Randomized trials to guide treatment of anxiety and depression in patients with Parkinson’s disease (PD) are limited, the researchers noted. However, data from a longitudinal study showed that PD patients whose depression remitted spontaneously or responded to treatment were able to attain a level of function similar to that of never-depressed PD patients, Dr. Pontone and colleagues said.

The researchers offered a pair of treatment algorithms to help guide clinicians in managing depression and anxiety in PD. However, a caveat to keep in mind is that “the benefit of antidepressant medications, used for depression or anxiety, can be confounded when motor symptoms are not optimally treated,” the researchers emphasized.

For depression, the researchers advised starting with some lab work; “at a minimum we suggest checking a complete blood count, metabolic panel, TSH, B12, and folate,” they noted. They recommended an antidepressant, cognitive-behavioral therapy, or both, as a first-line treatment, such as monotherapy with selective norepinephrine reuptake inhibitors or selective serotonin reuptake inhibitors. They advised titrating the chosen monotherapy to a minimum effective dose over a 2- to 3-week period to assess response.

“We recommend continuing antidepressant therapy for at least 1 year based on literature in non-PD populations and anecdotal clinical experience. At 1 year, if not in remission, consider continuing treatment or augmenting to improve response,” the researchers said.

Based on the current DSM-5 criteria, up to one-third of PD patients have an unspecified anxiety disorder, the researchers said, and they recommended using anxiety rating scales to diagnose anxiety in PD. “Given the high prevalence of atypical anxiety syndromes in PD and their potential association with both motor and nonmotor symptoms of the disease, working with the neurologist to achieve optimal control of PD is an essential first step to alleviating anxiety,” they emphasized.

The researchers also advised addressing comorbidities, including cardiovascular disease, chronic pain, diabetes, gastrointestinal issues, hyperthyroidism, and lung disease, all of which can be associated with anxiety. Once comorbidities are addressed, they advised caution given the lack of evidence for efficacy of both pharmacologic and nonpharmacologic anxiety treatments for PD patients. However, first-tier treatment for anxiety could include monotherapy with serotonin-norepinephrine reuptake inhibitors or selective serotonin reuptake inhibitors, they said.

PD patients with depression and anxiety also may benefit from nonpharmacologic interventions, including exercise, mindfulness, relaxation therapy, and cognitive behavioral therapy the researchers said.

Although the algorithm may not differ significantly from current treatment protocols, it highlights aspects unique to PD patients, the researchers said. In particular, the algorithm shows “that interventions used for motor symptoms, for example, dopamine agonists, may be especially potent for mood in the PD population and that augmentation strategies, such as antipsychotics and lithium, may not be well tolerated given their outsized risk of adverse events in PD,” they said.

“While an article of this kind cannot hope to address the gap in knowledge on comparative efficacy between interventions, it can guide readers on the best strategies for implementation and risk mitigation in PD – essentially focusing more on effectiveness,” they concluded.

Managing depression and anxiety in Parkinson’s disease should start with a review of medications and involve multidisciplinary care, according to a recent summary of evidence.

“Depression and anxiety have a complex relationship with the disease and while the exact mechanism for this association is unknown, both disturbances occur with increased prevalence across the disease course and when present earlier in life, increase the risk of PD by about twofold,” wrote Gregory M. Pontone, MD, of Johns Hopkins University, Baltimore, and colleagues.

Randomized trials to guide treatment of anxiety and depression in patients with Parkinson’s disease (PD) are limited, the researchers noted. However, data from a longitudinal study showed that PD patients whose depression remitted spontaneously or responded to treatment were able to attain a level of function similar to that of never-depressed PD patients, Dr. Pontone and colleagues said.

The researchers offered a pair of treatment algorithms to help guide clinicians in managing depression and anxiety in PD. However, a caveat to keep in mind is that “the benefit of antidepressant medications, used for depression or anxiety, can be confounded when motor symptoms are not optimally treated,” the researchers emphasized.

For depression, the researchers advised starting with some lab work; “at a minimum we suggest checking a complete blood count, metabolic panel, TSH, B12, and folate,” they noted. They recommended an antidepressant, cognitive-behavioral therapy, or both, as a first-line treatment, such as monotherapy with selective norepinephrine reuptake inhibitors or selective serotonin reuptake inhibitors. They advised titrating the chosen monotherapy to a minimum effective dose over a 2- to 3-week period to assess response.

“We recommend continuing antidepressant therapy for at least 1 year based on literature in non-PD populations and anecdotal clinical experience. At 1 year, if not in remission, consider continuing treatment or augmenting to improve response,” the researchers said.

Based on the current DSM-5 criteria, up to one-third of PD patients have an unspecified anxiety disorder, the researchers said, and they recommended using anxiety rating scales to diagnose anxiety in PD. “Given the high prevalence of atypical anxiety syndromes in PD and their potential association with both motor and nonmotor symptoms of the disease, working with the neurologist to achieve optimal control of PD is an essential first step to alleviating anxiety,” they emphasized.

The researchers also advised addressing comorbidities, including cardiovascular disease, chronic pain, diabetes, gastrointestinal issues, hyperthyroidism, and lung disease, all of which can be associated with anxiety. Once comorbidities are addressed, they advised caution given the lack of evidence for efficacy of both pharmacologic and nonpharmacologic anxiety treatments for PD patients. However, first-tier treatment for anxiety could include monotherapy with serotonin-norepinephrine reuptake inhibitors or selective serotonin reuptake inhibitors, they said.

Patients with cirrhosis treated at hospitals with the highest safety-net burden, defined by their proportion of Medicaid or uninsured patients, had a 5% higher mortality rate than patients who were treated at hospitals with the lowest burden, according to a study of over 300,000 patients.

The study, which was published in the Journal of Clinical Gastroenterology, analyzed inpatient data from the National Inpatient Sample (NIS) database focusing on a 4-year time span between 2012 and 2016. The hospitals were categorized by safety-net burden, which was defined as having either a high, medium, or low number of uninsured patients or patients with Medicaid.

This is the first-known study to evaluate the impact of a hospital’s safety-net burden on hospitalization outcomes in cirrhosis patients, wrote authors Robert J. Wong, MD, MS, of Stanford (Calif.) University and Grishma Hirode, MAS, of the University of Toronto. Previous studies have shown that safety-net hospitals, especially those with a high safety-net burden, have poorer patient outcomes. These hospitals also serve a patient population that is at high risk for chronic liver disease and cirrhosis.

The new analysis included 322,944 individual hospitalizations of patients with cirrhosis. Of these, 57.8% were male, 63.7% were White, 9.9% were Black, and 15.6% were Hispanic. In terms of safety-net burden, 107,446 hospitalizations were at high-burden hospitals, 103,508 were at medium-burden hospitals, and 111,990 hospitalizations were at low-burden hospitals.

Overall, cirrhosis-related hospitalizations in hospitals with the highest burden were found to have significantly greater odds of in-hospital mortality than the lowest tertile hospitals (odds ratio, 1.05, P = .044). The patients were also younger (mean age, 56.7 years vs. 59.8 years in low-burden hospitals). They also had a higher proportion of male patients, minority patients, Hispanic patients, and patients with Medicaid or no insurance.

The odds of hospitalization in the highest tertile hospitals were found to be significantly higher, compared with the middle and lowest tertiles for Blacks and Hispanics, compared with Whites (OR 1.26 and OR 1.63, respectively). Black patients (OR, 1.26; 95%CI, 1.17-1.35; P < .001) and Hispanic patients (OR, 1.63; 95% CI, 1.50-1.78; P< .001) were more likely to be admitted for care at high-burden hospitals (26% to 54%). In-hospital mortality rates among all hospitalizations were 5.95% and the rate did not significantly differ by hospital burden status.

“Despite adjusting for safety-net burden, our study continued to demonstrate ethnic disparities in in-hospital mortality among cirrhosis-related hospitalizations,” the researchers wrote. Overall, the odds of in-hospital mortality were 27% higher in Black patients as compared with White patients.

However, significantly lower mortality was observed in Hispanic patients as compared with White patients (4.9% vs. 6.0%, P < .001), but why this occurred was not entirely clear. “Hispanic patients may be more likely to have NASH [nonalcoholic steatohepatitis]-related cirrhosis, which generally has a slower disease progression, compared with [hepatitis C virus] or alcoholic cirrhosis. As such, it is likely that NASH-cirrhosis Hispanic patients had less severe disease at presentation,” the researchers wrote.
 

Study design has limitations, but shows concerning trends

The study findings were limited by several factors including the inability to show causality based on the observational study design and cross-sectional nature of the database, the researchers said. The NIS database records individual hospitalizations, not individual patient data which means that it may include repeat hospitalizations from the same patient. In addition, the study was limited by a lack of data on outpatient cirrhosis outcomes and non–liver-related comorbidities.

However, the finding that ethnic minorities with cirrhosis were significantly more likely to be hospitalized in high safety-net hospitals than White patients is concerning, and more research is needed, they said.

“These observations highlight that, while disparities in resources and health care delivery inherent to safety-net health systems may partly explain and provide opportunities to improve cirrhosis hospitalization care, they alone do not explain all of the ethnic disparities in cirrhosis outcomes observed,” they concluded.

The current study was important to conduct at this time because rates of cirrhosis are on the rise, Michael Volk, MD, of Loma Linda (Calif.) University Health, said in an interview. “Millions of patients receive care in safety-net hospitals across the country.”

Dr. Volk said that he was not surprised by the overall outcomes. “Unfortunately, I expected that patient outcomes would be worse at safety-net hospitals than wealthier hospitals. However, I was surprised that Blacks had higher in-hospital mortality than Whites, even after adjusting for the hospital.”

Dr. Volk echoed the study’s stated limitation of the lack of data to address disparities.

“Additional research is needed to determine whether the higher in-hospital mortality among Blacks is related to biological differences such as differential rates of disease progression, or social differences such as access to outpatient care,” he said.

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

Low adenoma detection rates (ADRs) were associated with a greater risk of death in colorectal cancer (CRC) patients, especially among those with high-risk adenomas, based on a review of more than 250,000 colonoscopies.

“Both performance quality of the endoscopist as well as specific characteristics of resected adenomas at colonoscopy are associated with colorectal cancer mortality,” but the impact of these combined factors on colorectal cancer mortality has not been examined on a large scale, according to Elisabeth A. Waldmann, MD, of the Medical University of Vienna and colleagues.

In a study published in Clinical Gastroenterology & Hepatology, the researchers reviewed 259,885 colonoscopies performed by 361 endoscopists. Over an average follow-up period of 59 months, 165 CRC-related deaths occurred.

Across all risk groups, CRC mortality was higher among patients whose colonoscopies yielded an ADR of less than 25%, although this was not statistically significant in all groups.

The researchers then stratified patients into those with a negative colonoscopy, those with low-risk adenomas (one to two adenomas less than 10 mm), and those with high-risk adenomas (advanced adenomas or at least three adenomas), with the negative colonoscopy group used as the reference group for comparisons. The average age of the patients was 61 years, and approximately half were women.

Endoscopists were classified as having an ADR of less than 25% or 25% and higher.

Among individuals with low-risk adenomas, CRC mortality was similar whether the ADR on a negative colonoscopy was less than 25% or 25% or higher (adjusted hazard ratios, 1.25 and 1.22, respectively). CRC mortality also remained unaffected by ADR in patients with negatively colonoscopies (aHR, 1.27).

By contrast, individuals with high-risk adenomas had a significantly increased risk of CRC death if their colonoscopy was performed by an endoscopist with an ADR of less than 25%, compared with those whose endoscopists had ADRs of 25% or higher (aHR, 2.25 and 1.35, respectively).

“Our study demonstrated that adding ADR to the risk stratification model improved risk assessment in all risk groups,” the researchers noted. “Importantly, stratification improved most for individuals with high-risk adenomas, the group demanding most resources in health care systems.”

The study findings were limited by several factors including the focus on only screening and surveillance colonoscopies, not including diagnostic colonoscopies, and the inability to adjust for comorbidities and lifestyle factors that might impact CRC mortality, the researchers noted. The 22.4% average ADR in the current study was low, compared with other studies, and could be a limitation as well, although previous guidelines recommend a target ADR of at least 20%.

“Despite the extensive body of literature supporting the importance of ADR in terms of CRC prevention, its implementation into clinical surveillance is challenging,” as physicians under pressure might try to game their ADRs, the researchers wrote.

The findings support the value of mandatory assessment of performance quality, the researchers added. However, “because of the potential possibility of gaming one’s ADR one conclusion drawn by the study results should be that endoscopists’ quality parameters should be monitored and those not meeting the standards trained to improve rather than requiring minimum ADRs as premise for offering screening colonoscopy.”
 

Improve performance, but don’t discount patient factors

The study is important at this time because colorectal cancer is the third-leading cause of cancer death in the United States, Atsushi Sakuraba, MD, of the University of Chicago said in an interview.

“Screening colonoscopy has been shown to decrease CRC mortality, but factors influencing outcomes after screening colonoscopies remain to be determined,” he said.

“It was expected that high-quality colonoscopy performed by an endoscopist with ADR of 25% or greater was associated with a lower risk for CRC death,” Dr. Sakuraba said. “The strength of the study is that the authors demonstrated that high-quality colonoscopy was more important in individuals with high-risk adenomas, such as advanced adenomas or at least three adenomas.”

The study findings have implications for practice in that they show the importance of monitoring performance quality in screening colonoscopy, Dr. Sakuraba said, “especially when patients have high-risk adenomas.” However, “the authors included only age and sex as variables, but the influence of other factors, such as smoking, [body mass index], and race, need to be studied.”

The researchers had no financial conflicts to disclose. Dr. Sakuraba had no financial conflicts to disclose.

The study findings were limited by several factors including the focus on only screening and surveillance colonoscopies, not including diagnostic colonoscopies, and the inability to adjust for comorbidities and lifestyle factors that might impact CRC mortality, the researchers noted. The 22.4% average ADR in the current study was low, compared with other studies, and could be a limitation as well, although previous guidelines recommend a target ADR of at least 20%.

“Despite the extensive body of literature supporting the importance of ADR in terms of CRC prevention, its implementation into clinical surveillance is challenging,” as physicians under pressure might try to game their ADRs, the researchers wrote.

The findings support the value of mandatory assessment of performance quality, the researchers added. However, “because of the potential possibility of gaming one’s ADR one conclusion drawn by the study results should be that endoscopists’ quality parameters should be monitored and those not meeting the standards trained to improve rather than requiring minimum ADRs as premise for offering screening colonoscopy.”
 

Improve performance, but don’t discount patient factors

The study is important at this time because colorectal cancer is the third-leading cause of cancer death in the United States, Atsushi Sakuraba, MD, of the University of Chicago said in an interview.

“Screening colonoscopy has been shown to decrease CRC mortality, but factors influencing outcomes after screening colonoscopies remain to be determined,” he said.

“It was expected that high-quality colonoscopy performed by an endoscopist with ADR of 25% or greater was associated with a lower risk for CRC death,” Dr. Sakuraba said. “The strength of the study is that the authors demonstrated that high-quality colonoscopy was more important in individuals with high-risk adenomas, such as advanced adenomas or at least three adenomas.”

The study findings have implications for practice in that they show the importance of monitoring performance quality in screening colonoscopy, Dr. Sakuraba said, “especially when patients have high-risk adenomas.” However, “the authors included only age and sex as variables, but the influence of other factors, such as smoking, [body mass index], and race, need to be studied.”

Lupus images in medical resource materials underrepresent patients with skin of color, based on data from a review of more than 1,400 images published between 2014 and 2019 in materials from a university’s online medical library.

Patients with skin of color who develop lupus tend to present earlier and with more severe cases, and often experience worse outcomes, compared with other populations, wrote Amaad Rana, MD, of Washington University, St. Louis, and colleagues. Medical resources in general have historically underrepresented patients of color, and the researchers reviewed lupus materials for a similar publication bias.

In a study published in Arthritis Care & Research, the investigators identified 1,417 images in rheumatology, dermatology, and internal medicine resources, including 119 medical textbooks, 15 medical journals, 2 online image libraries, and the online image collections of Google and UpToDate. An additional 24 images came from skin of color atlases.

Excluding the skin of color atlases, 56.4% of the images represented light skin, 35.1% showed medium skin, and 8.5% showed dark skin. Overall, publishers were more than twice as likely to portray light skin tones and were significantly less likely to portray dark skin tones (odds ratios, 2.59 and 0.19, respectively), compared with an equal representation of skin tones; however, the difference was not significant for portrayal of medium skin tones (OR, 1.08).

By specialty, dermatology was more inclusive of skin of color images than rheumatology or internal medicine, although the internal medicine sample size was too small for comparable analysis, the researchers noted. Dermatology textbooks were 2.42 times more likely and rheumatology textbooks were 4.87 times more likely to depict light skin tones than an equal representation of light, medium, and dark skin tones.

The researchers rated the skin color in the images using the New Immigrant Survey Skin Color Scale and categorized the images as representing light (NISSCS scores, 1-2), medium (NISSCS scores, 3-5), or dark skin (NISSCS scores, 6-10). Medical journals had the most images of dark skin, excluding skin of color atlases. In a comparison of specialties, dermatology materials included the most images of medium and darker skin tones.

The underrepresentation of skin of color patients can contribute to a limited knowledge of lupus presentation that could lead to disparate health outcomes, the researchers noted.

The study findings were limited by several factors, including the review of only the online textbooks and journals available through the medical library of a single university, the researchers noted. In addition, definitions of light, medium, and dark skin tones were variable among studies, and the researchers did not distinguish among lupus pathologies.

“Further research is needed to quantitatively assess the influence these materials have on healthcare providers’ ability to care for patients with lupus and SOC, and new material and strategies will be required to correct this disparity and promote equitable representation,” the researchers emphasized. “Ultimately, this will arm practitioners with the resources to competently treat patients with any skin color and work towards reducing disparities in health outcomes.”

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

A clinical prediction rule combining procalcitonin, absolute neutrophil count, and urinalysis effectively identified most febrile infants at low risk for serious bacterial infections, based on data from 702 individuals

The clinical prediction rule (CPR) described in 2019 in JAMA Pediatrics was developed by the Febrile Infant Working Group of the Pediatric Emergency Care Applied Research Network (PECARN) to identify febrile infants at low risk for serious bacterial infections in order to reduce unnecessary procedures, antibiotics use, and hospitalization, according to April Clawson, MD, of Arkansas Children’s Hospital, Little Rock, and colleagues.

In a poster presented at the Pediatric Academic Societies annual meeting, the researchers conducted an external validation of the rule via a retrospective, observational study of febrile infants aged 60 days and younger who presented to an urban pediatric ED between October 2014 and June 2019. The study population included 702 infants with an average age of 36 days. Approximately 45% were female, and 60% were White. Fever was defined as 38° C or greater. Exclusion criteria were prematurity, receipt of antibiotics in the past 48 hours, presence of an indwelling medical device, and evidence of focal infection (not including otitis media); those who were critically ill at presentation or had a previous medical condition were excluded as well, the researchers said. A serious bacterial infection (SBI) was defined as a urinary tract infection (UTI), bacteremia, or bacterial meningitis.

Based on the CPR, a patient is considered low risk for an SBI if all the following criteria are met: normal urinalysis (defined as absence of leukocyte esterase, nitrite, and 5 or less white blood cells per high power field); an absolute neutrophil count of 4,090/mL or less; and procalcitonin of 1.71 ng/mL or less.

Overall, 62 infants (8.8%) were diagnosed with an SBI, similar to the 9.3% seen in the parent study of the CPR, Dr. Clawson said.

Of these, 42 had a UTI only (6%), 10 had bacteremia only (1.4%), and 1 had meningitis only (0.1%). Another five infants had UTI with bacteremia (0.7%), and four had bacteremia and meningitis (0.6%).

According to the CPR, 432 infants met criteria for low risk and 270 were considered high risk. A total of five infants who were classified as low risk had SBIs, including two with UTIs, two with bacteremia, and one with meningitis.

“The CPR derived and validated by Kupperman et al. had a decreased sensitivity for the patients in our study and missed some SBIs,” Dr. Clawson noted. “However, it had a strong negative predictive value, so it may still be a useful CPR.”

The sensitivity for the CPR in the parent study and the current study was 97.7 and 91.9, respectively; specificity was 60 and 66.7, respectively. The negative predictive values for the parent and current studies were 99.6 and 98.8, respectively, and the positive predictive values were 20.7 and 21.1.

The results support the potential of the CPR, but more external validation is needed, they said.
 

PECARN rule keeps it simple

“It has always been a challenge to identify infants with fever with serious bacterial infections when they are well-appearing,” Yashas Nathani, MD, of Oklahoma University, Oklahoma City, said in an interview. “The clinical prediction rule offers a simple, step-by-step approach for pediatricians and emergency medicine physicians to stratify infants in high or low risk categories for SBIs. However, as with everything, validation of protocols, guidelines and decision-making algorithms is extremely important, especially as more clinicians start to employ this CPR to their daily practice. This study objectively puts the CPR to the test and offers an independent external validation.

“Although this study had a lower sensitivity in identifying infants with SBI using the clinical prediction rule as compared to the original study, the robust validation of negative predictive value is extremely important and not surprising,” said Dr. Nathani. “The goal of this CPR is to identify infants with low-risk for SBI and the stated NPV helps clinicians in doing just that.”

Overall, “the clinical prediction rule is a fantastic resource for physicians to identify potentially sick infants with fever, especially the ones that appear well on initial evaluation,” said Dr. Nathani. However, “it is important to acknowledge that this is merely a guideline, and not an absolute rule. Clinicians also must remain cautious, as this rule does not incorporate the presence of viral pathogens as a factor.

“It is important to continue the scientific quest to refine our approach in identifying infants with serious bacterial infections when fever is the only presentation,” Dr. Nathani noted. “Additional research is needed to continue fine-tuning this CPR and the thresholds for procalcitonin and absolute neutrophil counts to improve the sensitivity and specificity.” Research also is needed to explore whether this CPR can be extended to incorporate viral testing, “as a large number of infants with fever have viral pathogens as the primary etiology,” he concluded.
