RESUMO
BACKGROUND/AIMS: When participants in individually randomized group treatment trials are treated by multiple clinicians or in multiple group treatment sessions throughout the trial, this induces partially nested clusters which can affect the power of a trial. We investigate this issue in the Whole Health Options and Pain Education trial, a three-arm pragmatic, individually randomized clinical trial. We evaluate whether partial clusters due to multiple visits delivered by different clinicians in the Whole Health Team arm and dynamic participant groups due to changing group leaders and/or participants across treatment sessions during treatment delivery in the Primary Care Group Education arm may impact the power of the trial. We also present a Bayesian approach to estimate the intraclass correlation coefficients. METHODS: We present statistical models for each treatment arm of Whole Health Options and Pain Education trial in which power is estimated under different intraclass correlation coefficients and mapping matrices between participants and clinicians or treatment sessions. Power calculations are based on pairwise comparisons. In practice, sample size calculations depend on estimates of the intraclass correlation coefficients at the treatment sessions and clinician levels. To accommodate such complexities, we present a Bayesian framework for the estimation of intraclass correlation coefficients under different participant-to-session and participant-to-clinician mapping scenarios. We simulated continuous outcome data based on various clinical scenarios in Whole Health Options and Pain Education trial using a range of intraclass correlation coefficients and mapping matrices and used Gibbs samplers with conjugate priors to obtain posteriors of the intraclass correlation coefficients under those different scenarios. Posterior means and medians and their biases are calculated for the intraclass correlation coefficients to evaluate the operating characteristics of the Bayesian intraclass correlation coefficient estimators. RESULTS: Power for Whole Health Team versus Primary Care Group Education is sensitive to the intraclass correlation coefficient in the Whole Health Team arm. In these two arms, an increased number of clinicians, more evenly distributed workload of clinicians, or more homogeneous treatment group sizes leads to increased power. Our simulation study for the intraclass correlation coefficient estimation indicates that the posterior mean intraclass correlation coefficient estimator has less bias when the true intraclass correlation coefficients are large (i.e. 0.10), but when the intraclass correlation coefficient is small (i.e. 0.01), the posterior median intraclass correlation coefficient estimator is less biased. CONCLUSION: Knowledge of intraclass correlation coefficients and the structure of clustering are critical to the design of individually randomized group treatment trials with partially nested clusters. We demonstrate that the intraclass correlation coefficient of the Whole Health Team arm can affect power in the Whole Health Options and Pain Education trial. A Bayesian approach provides a flexible procedure for estimating the intraclass correlation coefficients under complex scenarios. More work is needed to educate the research community about the individually randomized group treatment design and encourage publication of intraclass correlation coefficients to help inform future trial designs.

BACKGROUND/AIM: In clinical trials, there is potential for bias from unblinded observers that may influence ascertainment of outcomes. This issue arose in the Strategies to Reduce Injuries and Develop Confidence in Elders trial, a cluster randomized trial to test a multicomponent intervention versus enhanced usual care (control) to prevent serious fall injuries, originally defined as a fall injury leading to medical attention. An unblinded nurse falls care manager administered the intervention, while the usual care arm did not involve contact with a falls care manager. Thus, there was an opportunity for falls care managers to refer participants reporting falls to seek medical attention. Since this type of observer bias could not occur in the usual care arm, there was potential for additional falls to be reported in the intervention arm, leading to dilution of the intervention effect and a reduction in study power. We describe the clinical basis for ascertainment bias, the statistical approach used to assess it, and its effect on study power. METHODS: The prespecified interim monitoring plan included a decision algorithm for assessing ascertainment bias and adapting (revising) the primary outcome definition, if necessary. The original definition categorized serious fall injuries requiring medical attention into Type 1 (fracture other than thoracic/lumbar vertebral, joint dislocation, cut requiring closure) and Type 2 (head injury, sprain or strain, bruising or swelling, other). The revised definition, proposed by the monitoring plan, excluded Type 2 injuries that did not necessarily require an overnight hospitalization since these would be most subject to bias. These injuries were categorized into those with (Type 2b) and without (Type 2c) medical attention. The remaining Type 2a injuries required medical attention and an overnight hospitalization. We used the ratio of 2b/(2b + 2c) in intervention versus control as a measure of ascertainment bias; ratios > 1 indicated the likelihood of falls care manager bias. We determined the effect of ascertainment bias on study power for the revised (Types 1 and 2a) versus original definition (Types 1, 2a, and 2b). RESULTS: The estimate of ascertainment bias was 1.14 (95% confidence interval: 0.98, 1.30), providing evidence of the likelihood of falls care manager bias. We estimated that this bias diluted the hazard ratio from the hypothesized 0.80 to 0.86 and reduced power to under 80% for the original primary outcome definition. In contrast, adapting the revised definition maintained study power at nearly 90%. CONCLUSION: There was evidence of ascertainment bias in the Strategies to Reduce Injuries and Develop Confidence in Elders trial. The decision to adapt the primary outcome definition reduced the likelihood of this bias while preserving the intervention effect and study power.

BACKGROUND: Cure from chronic hepatitis C virus (HCV) infection is readily achievable with direct-acting antivirals (DAA), but little is known about optimal management after treatment. Weight gained after DAA treatment may mitigate benefits or increase risk for liver disease progression. As the single largest sample of HCV-infected individuals receiving DAA treatment in the United States, the Veterans Affairs (VA) Birth Cohort is an ideal setting to assess weight gain after DAA treatment. METHODS: We performed a prospective study of patients dispensed DAA therapy from January 2014 to June 2015. Weight change was calculated as the difference in weight from sustained virologic response (SVR) determination to 2 years later. Demographic, weight, height, prescription, laboratory, and diagnosis code data were used for covariate definitions. We used multiple logistic regression to assess the association between candidate predictors and excess weight gain (≥ 10 lbs) after 2 years. RESULTS: Among 11,469 patients, 78.0% of patients were already overweight or obese at treatment initiation. Overall, SVR was achieved in 97.0% of patients. After 2 years, 52.6% of patients gained weight and 19.8% gained excess weight. In those with SVR, weight gain was as high as 38.2 lbs, with the top 10% gaining ≥ 16.5 lbs. Only 1% of those with obesity at treatment initiation normalized their weight class after 2 years. Significant predictors of post-SVR weight gain were SVR achievement, lower age, high FIB-4 score, cirrhosis, and weight class at treatment initiation. CONCLUSION: Weight gain is common after DAA treatment, even among those who are overweight or obese prior to treatment. Major predictors include age, baseline weight, alcohol, cirrhosis, and SVR. Everyone receiving DAAs should be counseled against weight gain with a particular emphasis among those at higher risk.

RESUMO
While the traditional clinical trial design lays emphasis on testing the treatment effect between randomly assigned groups, it ignores the role of patient preference for a particular treatment in the trial. Yet, for healthcare providers who seek to optimize the patient-centered treatment strategy, the evaluation of a patient's psychology toward each treatment could be a key consideration. The two-stage randomized trial design allows researchers to test patient's preference and selection effects, in addition to the treatment effect. The current methodology for the two-stage design is limited to continuous and binary outcomes; this article extends the model to include count outcomes. The test statistics for preference, selection, and treatment effects are derived. Closed-form sample size formulae are presented for each effect. Simulations are presented to demonstrate the properties of the unstratified and stratified designs. Finally, we apply methods to the use of antimicrobials at the end of life to demonstrate the applicability of the methods.

BACKGROUND: Young gay and bisexual men disproportionately experience depression, anxiety, and substance use problems and are among the highest risk group for HIV infection in the U.S. Diverse methods locate the source of these health disparities in young gay and bisexual men's exposure to minority stress. In fact, minority stress, psychiatric morbidity, substance use, and HIV risk fuel each other, forming a synergistic threat to young gay and bisexual men's health. Yet no known intervention addresses minority stress to improve mental health, substance use problems, or their joint impact on HIV risk in this population. This paper describes the design of a study to test the efficacy of such an intervention, called ESTEEM (Effective Skills to Empower Effective Men), a 10-session skills-building intervention designed to reduce young gay and bisexual men's co-occurring health risks by addressing the underlying cognitive, affective, and behavioral pathways through which minority stress impairs health. METHODS: This study, funded by the National Institute of Mental Health, is a three-arm randomized controlled trial to examine (1) the efficacy of ESTEEM compared to community mental health treatment and HIV counseling and testing and (2) whether ESTEEM works through its hypothesized cognitive, affective, and behavioral minority stress processes. Our primary outcome, measured 8 months after baseline, is condomless anal sex in the absence of PrEP or known undetectable viral load of HIV+ primary partners. Secondary outcomes include depression, anxiety, substance use, sexual compulsivity, and PrEP uptake, also measured 8 months after baseline. DISCUSSION: Delivering specific stand-alone treatments for specific mental, behavioral, and sexual health problems represents the current state of evidence-based practice. However, dissemination and implementation of this one treatment-one problem approach has not been ideal. A single intervention that reduces young gay and bisexual men's depression, anxiety, substance use, and HIV risk by reducing the common minority stress pathways across these problems would represent an efficient, cost-effective alternative to currently isolated approaches, and holds great promise for reducing sexual orientation health disparities among young men. TRIAL REGISTRATION: Registered October 10, 2016 to ClinicalTrials.gov Identifier: NCT02929069 .

BACKGROUND & AIMS: Universal one-time antibody testing for hepatitis C virus (HCV) infection has been recommended by the centers for disease control (CDC) and the United States preventative services task force (USPSTF) for Americans born 1945-1965 (birth cohort). Limited data exists addressing national HCV testing practices. We studied patterns and predictors of HCV testing across the U.S. within the birth cohort utilizing data from the national corporate data warehouse of the U.S. Veterans Administration (VA) health system. METHODS: Testing was defined as any HCV test including antibody, RNA or genotype performed during 2000-2013. RESULTS: Of 6,669,388 birth cohort veterans, 4,221,135 (63%) received care within the VA from 2000-2013 with two or more visits. Of this group, 2,139,935 (51%) had HCV testing with 8.1% HCV antibody and 5.4% RNA positive. Significant variation in testing was observed across centers (range: 7-83%). Older, male, African-Americans, with established risk factors and receiving care from urban centers of excellence were more likely to be tested. Among veterans free of other established risk factors (HIV negative, HBV negative, ALT ⩽40U/L, FIB-4 ⩽1.45, or APRI <0.5), HCV antibody and RNA were positive in 2.8% and 0.9%, respectively, comparable to established national average. At least 2.4-4.4% of veterans had scores suggesting advanced fibrosis (APRI ⩾1.5 or FIB-4 >3.25) with >30-43% having positive HCV RNA but >16-20% yet to undergo testing for HCV. CONCLUSIONS: Significant disparities are observed in HCV testing within the United States VA health system. Examination of the predictors of testing and HCV positivity may help inform national screening policies. LAY SUMMARY: Analysis of United States Veterans Administration data show significant disparities in hepatitis C virus testing of veterans born 1945-1965 (birth cohort). A fifth of those not tested had evidence of advanced liver fibrosis. Our data suggests some predictors for this disparity and will potentially help inform future policy measures in the era of universal birth cohort testing for HCV.

GOALS: To investigate the role of self-efficacy (SE) during hepatitis C virus (HCV) treatment. BACKGROUND: Adherence to chronic HCV treatment is critical. SE is an important predictor of medication adherence in a number of chronic disease populations and medication regimens, but its role during HCV treatment remains unknown. STUDY: Data from the prospective Virahep-C study were analyzed to examine relationships between SE and patient-driven deviations (ie, missed doses measured using electronic pill caps, and nonpersistence) from adherence to HCV antiviral treatment. SE was measured using the 17-item HCV Treatment Self-Efficacy scale. This measure provides a global estimate of a patient's confidence to undergo and adhere to HCV treatment, and can estimate SE in 4 underlying domains: communication SE (ie, confidence to communicate with health care provider), physical coping SE (ie, confidence to cope with physical side effects), psychological coping SE (ie, confidence to cope with psychiatric side effects), and treatment adherence SE (ie, confidence to take all medications as prescribed and attend doctor visits). Generalized estimating equations and Cox proportional hazards models were used to assess associations between SE and missed doses and nonpersistence, respectively. RESULTS: SE was associated with being in a relationship, educated, privately insured, and less depressed. Higher communication SE at TW24 reduced the risk of missed doses between TW24 and TW48. Higher baseline treatment adherence SE reduced the likelihood of nonpersistence between baseline and TW24. CONCLUSIONS: SE's relationship to HCV treatment adherence has promising clinical and research implications.

OBJECTIVES: To pilot a pharmacist-led, patient centered medication management program. DESIGN: Prospective, single arm trial. SETTING: Academic geriatric psychiatry outpatient clinic. PARTICIPANTS: Outpatients at least 65 years old, proxy available if demented, and on two or more psychiatric medications. INTERVENTION: A clinical pharmacist completed a baseline medication review and made evidence-based recommendations that were implemented by the pharmacist after discussion with the physician. The pharmacist made a minimum of monthly contact for 6 months to review medications and related issues. MEASUREMENTS: The primary outcome was the change in number of medication related problems over time (3 and 6 months) as defined by a predetermined classification system. RESULTS: The mean age of the 27 patients was 75 years, 10 of whom required a proxy to participate. On average, patients had nine chronic conditions and were taking 14 medications. The mean number (SD; range) of medication related problems at baseline was 4.1 (2.2; 0-8) and at 3 and 6 months were 3.6 (2.4, 0-9) and 3.4 (2.1; 0-8), respectively. Most follow-up problems were new (80% and 89% at 3 and 6 months, respectively). CONCLUSION: Using a pharmacist to deliver a medication management program was feasible and addressed existing problems. New problems, however, developed over a short interval (3-6 months), suggesting that ongoing intervention is required.

BACKGROUND: Poor medication adherence due to high drug costs is a barrier to optimal health outcomes among low-income uninsured patients with chronic conditions. Charitable pharmacy assistance programs provide medications to such patients, but little is known about the utilization patterns of program participants. METHODS: We used a retrospective cohort design to investigate 6-month outcomes for participants in the University of North Carolina (UNC) Health Care Pharmacy Assistance Program (PAP) who received medications indicated for hypertension, diabetes, and/or hyperlipidemia from 2009 through 2011. Logistic regression was used to analyze predictors of medication adherence and to evaluate the association between adherence and use of emergency and inpatient care. RESULTS: The 3 study cohorts included 866 patients receiving antihypertensive agents, 265 patients receiving oral glucose-lowering agents, and 455 patients receiving statins. When assessed 6 months after program enrollment, 52%, 45%, and 38% of patients in these 3 groups, respectively, were at least 80% adherent to treatment. Adherent patients in all cohorts had lower odds of requiring inpatient or emergency department care, but the decrease was only statistically significant among those taking antihypertensive agents (odds ratio for hospitalization = 0.58; 95% confidence interval, 0.39-0.87). LIMITATIONS: Selection bias and inability to capture utilization data from sources other than UNC Health Care may have biased results. CONCLUSION: Approximately 50% of PAP participants were adherent to chronic disease medications. Adherence to such therapies among patients who are receiving financial assistance with medications may reduce their need for costly health care services. Future research should assess the long-term ability of pharmacy assistance programs to promote medication adherence and should examine alternative strategies for improving adherence and health outcomes among low-income uninsured patients.

BACKGROUND: UNC Health Care has a Pharmacy Assistance Program (PAP) that provides financial assistance to uninsured patients in North Carolina who need prescription medications. Despite significant investment in the program, little is known about the patients accessing it or the specific health care services they use. Our objectives were to describe the PAP population, to examine their use of prescription medications and health services, and to characterize changes in prescription medication use and expenditures from 2009 through 2011. METHODS: We used a repeated cross-sectional study design, merging prescription claims with health records from Carolina Data Warehouse for Health, to measure use of prescription medications and use of inpatient, outpatient, and emergency department care by PAP participants. Prescription claims were grouped into therapeutic categories. We generated descriptive statistics for key variables to examine health service utilization from 2009 through 2011. RESULTS: From 2009 through 2011, PAP served 7,180 patients from 81 counties in North Carolina. PAP users received a mean of 23 prescriptions, at an average cost of $754 per recipient per year. An average of $2.93 million per year was spent on the program, with an 8% rise in spending from 2009 to 2011. Inpatient care and emergency department care were utilized by 30% and 31% of PAP users, respectively, and there was minimal change in these rates over 3 years. LIMITATIONS: Data were limited to medications dispensed through PAP and to health services provided by UNC Health Care. CONCLUSIONS: With the state's decision to not expand Medicaid, PAP will continue to be an important resource for North Carolina's low income citizens.

BACKGROUND: Research on diet quality and ovarian cancer is limited. We examined the association between diet quality and ovarian cancer risk and survival in a large prospective cohort. METHODS: We used data from women in the prospective National Institutes of Health-AARP Diet and Health Study enrolled from 1995 to 1996 who were aged 50-71 years at baseline with follow-up through December 31, 2017. Participants completed a 124-item food frequency questionnaire at baseline, and diet quality was assessed via the Healthy Eating Index-2015, the alternate Mediterranean diet score, and the Dietary Approaches to Stop Hypertension score. Primary outcomes were first primary epithelial ovarian cancer diagnosis from cancer registry data and among those diagnosed with ovarian cancer all-cause mortality. We used a semi-Markov multistate model with Cox proportional hazards regression to account for semicompeting events. RESULTS: Among 150â643 participants with a median follow-up time of 20.5 years, 1107 individuals were diagnosed with a first primary epithelial ovarian cancer. There was no evidence of an association between diet quality and ovarian cancer risk. Among those diagnosed with epithelial ovarian cancer, 893 deaths occurred with a median survival of 2.5 years. Better prediagnosis diet quality, according to the Healthy Eating Index-2015 (quintile 5 vs quintile 1: hazard ratio [HR] = 0.75, 95% confidence interval [CI] = 0.60 to 0.93) and alternate Mediterranean diet score (quintile 5 vs quintile 1: HR = 0.68, 95% CI = 0.53 to 0.87), was associated with lower all-cause mortality. There was no evidence of an association between Dietary Approaches to Stop Hypertension score and all-cause mortality. CONCLUSIONS: Better prediagnosis diet quality was associated with lower all-cause mortality after ovarian cancer diagnosis but was not associated with ovarian cancer risk.

OBJECTIVES: To measure adherence in older adults with the use of a novel visual scale screening tool and to compare this adherence measurement with other adherence measures. DESIGN: Noncontrolled prospective intervention trial. SETTING: Geriatric psychiatry clinic in North Carolina between February 2008 and July 2009. PARTICIPANTS: 27 geriatric psychiatry clinic patients were identified as meeting eligibility criteria, and 26 of these participants completed the baseline and 3- and 6-month visits. INTERVENTION: Pharmacist-provided medication management program. MAIN OUTCOME MEASURES: A novel visual scale, the Medometer, assessed patient adherence to individual medications and aggregate medication regimen. The Medometer was compared with pharmacist subjective adherence assessment and the four-item Morisky scale. RESULTS: Aggregate regimen adherence based on the Morisky scale was 44%, 50%, and 38% at baseline, 3 months, and 6 months, respectively. Similarly it was 48%, 50%, and 46%, respectively, for the aggregate Medometer measurement. Measured individually by drug, average adherence at baseline, 3 months, and 6 months was 44%, 50%, and 35%, respectively, with the Medometer and 74%, 65%, and 50%, respectively, for the pharmacist's subjective assessment. Less stringent definitions for categorizing adherence identified a higher proportion of patients as adherent, with similar trends across measures. Individual medication and aggregate regimen adherence estimates provided face validity for the Medometer, with moderate agreement with other measures. CONCLUSION: The Medometer is a visual scale that can assess individual medication and overall medication regimen adherence. It performed well in this pilot study, but additional research is needed to assess the reliability and validity of this tool in larger, diverse populations and to test the effectiveness of this tool in guiding pharmacists' efforts to improve medication outcomes.

One in three adults in the United States has obesity; a chronic disease that is implicated in the etiology of at least 14 cancers. Cancer is the leading cause of death among U.S. Hispanic/Latino adults and the second most common cause of death, after cardiovascular disease, for Black adults. Our country's legacy in overt discrimination (e.g., slavery, segregation) generated inequities across all spheres in which people function as defined by the socioecological model-biological, individual, community, structural-and two of the many areas in which it manifests today are the disproportionate burden of obesity and obesity-related cancers in populations of color. Inequities due to environmental, social, and economic factors may predispose individuals to poor lifestyle behaviors by hindering an individual's opportunity to make healthy lifestyles choices. In this review, we examined the evidence on obesity and the lifestyle guidelines for cancer prevention in relation to cancer risk and outcomes for Black and Hispanic/Latino adults. We also discussed the role of structural and societal inequities on the ability of these two communities to adopt and maintain healthful lifestyle behaviors in accordance with the lifestyle guidelines for cancer prevention and control.

Although gay-related rejection sensitivity (RS) is associated with social anxiety among sexual minority men, little attention has been given to the validity of gay-related RS measures and to individual differences that might moderate the association between gay-related RS and social anxiety. In a population-based sample of sexual minority men, Study 1 (N = 114) investigated the incremental validity of gay-related RS and showed that gay-related RS scores significantly added to the prediction of social anxiety symptoms, even after controlling for personal RS scores. In a clinical sample of sexual minority men, Study 2 (N = 254) examined interrelationships among gay-related RS, sexual identity strength, and current social anxiety symptoms and disorder diagnosis. Results revealed that the expected count of current social anxiety symptoms and the odds of social anxiety disorder diagnosis, as assessed with a structured diagnostic interview, increased as a function of gay-related RS scores. Sexual identity strength moderated these relationships, such that the associations between gay-related RS scores and interviewer-assessed social anxiety symptoms and disorder were only significant for those high, but not low, in sexual identity strength. Together, results from the present studies lend support to the incremental validity of gay-related RS scales in predicting social anxiety symptoms and suggest that sexual minority men who consider their sexual orientation to be self-defining might be particularly vulnerable to the mental health correlates of gay-related RS.
RESUMO
Importance: Some payers and clinicians require alcohol abstinence to receive direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection. Objective: To evaluate whether alcohol use at DAA treatment initiation is associated with decreased likelihood of sustained virologic response (SVR). Design, Setting, and Participants: This retrospective cohort study used electronic health records from the US Department of Veterans Affairs (VA), the largest integrated national health care system that provides unrestricted access to HCV treatment. Participants included all patients born between 1945 and 1965 who were dispensed DAA therapy between January 1, 2014, and June 30, 2018. Data analysis was completed in November 2020 with updated sensitivity analyses performed in 2023. Exposure: Alcohol use categories were generated using responses to the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) questionnaire and International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnoses for alcohol use disorder (AUD): abstinent without history of AUD, abstinent with history of AUD, lower-risk consumption, moderate-risk consumption, and high-risk consumption or AUD. Main Outcomes and Measures: The primary outcome was SVR, which was defined as undetectable HCV RNA for 12 weeks or longer after completion of DAA therapy. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% CIs of SVR associated with alcohol category. Results: Among 69â¯229 patients who initiated DAA therapy (mean [SD] age, 62.6 [4.5] years; 67â¯150 men [97.0%]; 34â¯655 non-Hispanic White individuals [50.1%]; 28â¯094 non-Hispanic Black individuals [40.6%]; 58â¯477 individuals [84.5%] with HCV genotype 1), 65â¯355 (94.4%) achieved SVR. A total of 32â¯290 individuals (46.6%) were abstinent without AUD, 9192 (13.3%) were abstinent with AUD, 13â¯415 (19.4%) had lower-risk consumption, 3117 (4.5%) had moderate-risk consumption, and 11â¯215 (16.2%) had high-risk consumption or AUD. After adjustment for potential confounding variables, there was no difference in SVR across alcohol use categories, even for patients with high-risk consumption or AUD (OR, 0.95; 95% CI, 0.85-1.07). There was no evidence of interaction by stage of hepatic fibrosis measured by fibrosis-4 score (P for interaction = .30). Conclusions and Relevance: In this cohort study, alcohol use and AUD were not associated with lower odds of SVR. Restricting access to DAA therapy according to alcohol use creates an unnecessary barrier to patients and challenges HCV elimination goals.

Importance: Chemotherapy-induced peripheral neuropathy (CIPN), one of the most common and severe adverse effects of chemotherapy, is associated with worse quality of life among survivors of ovarian cancer. Currently, there is no effective treatment for CIPN. Objective: To evaluate the effect of a 6-month aerobic exercise intervention vs attention-control on CIPN among women treated for ovarian cancer in the Women's Activity and Lifestyle Study in Connecticut (WALC) to provide evidence to inform the guidelines and recommendations for prevention or treatment of CIPN. Design, Setting, and Participants: This prespecified secondary analysis evaluated the Women's Activity and Lifestyle Study in Connecticut (WALC), a multicentered, open-label, population-based, phase 3 randomized clinical trial of an aerobic exercise intervention vs attention control for CIPN in patients who were diagnosed with ovarian cancer. Only WALC participants who received chemotherapy were included in this analysis. Participants were randomized 1:1 to either a 6-month aerobic exercise intervention or to attention control. All analyses were conducted between September 2022 and January 2023. Interventions: The exercise intervention consisted of home-based moderate-intensity aerobic exercise facilitated by weekly telephone counseling from an American College of Sports Medicine/American Cancer Society-certified cancer exercise trainer. Attention control involved weekly health education telephone calls from a WALC staff member. Main Outcomes and Measure: Change in CIPN was the primary outcome in this secondary analysis. This outcome was represented by CIPN severity, which was self-measured by participants at baseline and 6 months using the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity scale, with a score range of 0 to 44. A mixed-effects model was used to assess the 6-month change in CIPN between the exercise intervention and attention control arms. Results: Of the 134 participants (all females; mean [SD] age, 57.5 [8.3] years) included in the analysis, 69 were in the exercise intervention arm and 65 were in the attention control arm. The mean (SD) time since diagnosis was 1.7 (1.0) years. The mean (SD) baseline CIPN scores were 8.1 (5.6) in the exercise intervention arm and 8.8 (7.9) in the attention control arm (P = .56). At 6 months, the self-reported CIPN score was reduced by 1.3 (95% CI, -2.3 to -0.2) points in the exercise intervention arm compared with an increase of 0.4 (95% CI, -0.8 to 1.5) points in the attention control arm. The between-group difference was -1.6 (95% CI, -3.1 to -0.2) points. The point estimate was larger among the 127 patients with CIPN symptoms at enrollment (-2.0; 95% CI, -3.6 to -0.5 points). Conclusions and Relevance: Findings of this secondary analysis of the WALC trial indicate that a 6-month aerobic exercise intervention vs attention control significantly improved self-reported CIPN among patients who were treated for ovarian cancer. While replication of the findings in other studies is warranted, incorporating referrals to exercise programs into standard oncology care could reduce CIPN symptoms and increase quality of life in patients with ovarian cancer.

STUDY OBJECTIVE: The purpose of this study is to determine whether older adults presenting to the emergency department (ED) with pain are less likely to receive pain medication than younger adults. METHODS: Pain-related visits to US EDs were identified with reason-for-visit codes from 7 years (2003 to 2009) of the National Hospital Ambulatory Medical Care Survey. The primary outcome was the administration of an analgesic. The percentage of patients receiving analgesics in 4 age groups was adjusted for measured covariates, including pain severity. RESULTS: Pain-related visits accounted for 88,031 (46.9%) ED visits by patients aged 18 years or older during the 7-year period. There were 7,585 pain-related ED visits by patients aged 75 years or older, representing an estimated 3.65 million US ED visits annually. In comparing survey-weighted unadjusted estimates, pain-related visits by patients aged 75 years or older were less likely than visits by patients aged 35 to 54 years to result in administration of an analgesic (49% versus 68.3%) or an opioid (34.8% versus 49.3%). Absolute differences in rates of analgesic and opioid administration persisted after adjustment for sex, race/ethnicity, pain severity, and other factors and multiple imputation of missing pain severity data, with visits by patients aged 75 years and older being 19.6% (95% confidence interval 17.8% to 21.4%) less likely than visits by patients aged 35 to 54 years to receive an analgesic and 14.6% (95% confidence interval 12.8% to 16.4%) less likely to receive an opioid. CONCLUSION: Patients aged 75 years and older with pain-related ED visits are less likely to receive pain medication than patients aged 35 to 54 years.

OBJECTIVE: Effective Skills to Empower Effective Men (ESTEEM) represents the first intervention to address the psychological pathways through which minority stress undermines young sexual minority men's (SMM's) mental and sexual health using transdiagnostic cognitive-behavioral therapy. This study compared the efficacy of ESTEEM against two existing interventions. METHOD: Participants were young HIV-negative SMM (N = 254; ages = 18-35; 67.2% racial/ethnic minority) experiencing a depression, anxiety, and/or stress-/trauma-related disorder and past-90-day HIV transmission risk behavior. After completing HIV testing and counseling, participants were randomized to receive 10-session ESTEEM (n = 100); 10-session community-based LGBQ-affirmative counseling (n = 102); or only HIV testing and counseling (n = 52). RESULTS: For the primary outcome of any HIV transmission risk behavior at 8 months, ESTEEM was not significantly associated with greater reduction compared to HIV testing and counseling (risk ratio [RR] = 0.89, p = .52). Supportive analyses of the frequency of HIV transmission risk behavior at 8 months showed a nonsignificant difference between ESTEEM compared to HIV testing and counseling (RR = 0.69) and LGBQ-affirmative counseling (RR = 0.62). For secondary outcomes (e.g., depression, anxiety, substance use, suicidality, number of mental health diagnoses) at 8 months, ESTEEM had a larger effect size than the two comparison conditions, but these comparisons did not reach statistical significance when adjusting for the false discovery rate. Observed effect sizes for condition comparisons were smaller than the effect sizes used to power the study. In exploratory analyses, ESTEEM showed promise for reducing comorbidity. CONCLUSIONS: Because the control conditions were associated with stronger effects than anticipated, and given the heterogeneous nature of transdiagnostic outcomes, the study possessed insufficient power to statistically detect the consistently small-to-moderate benefit of ESTEEM compared to the two control conditions.

BACKGROUND: Better understanding of the association between characteristics of patients hospitalized with coronavirus disease 2019 (COVID-19) and outcome is needed to further improve upon patient management. METHODS: Immunophenotyping Assessment in a COVID-19 Cohort (IMPACC) is a prospective, observational study of 1164 patients from 20 hospitals across the United States. Disease severity was assessed using a 7-point ordinal scale based on degree of respiratory illness. Patients were prospectively surveyed for 1 year after discharge for post-acute sequalae of COVID-19 (PASC) through quarterly surveys. Demographics, comorbidities, radiographic findings, clinical laboratory values, SARS-CoV-2 PCR and serology were captured over a 28-day period. Multivariable logistic regression was performed. FINDINGS: The median age was 59 years (interquartile range [IQR] 20); 711 (61%) were men; overall mortality was 14%, and 228 (20%) required invasive mechanical ventilation. Unsupervised clustering of ordinal score over time revealed distinct disease course trajectories. Risk factors associated with prolonged hospitalization or death by day 28 included age ≥ 65 years (odds ratio [OR], 2.01; 95% CI 1.28-3.17), Hispanic ethnicity (OR, 1.71; 95% CI 1.13-2.57), elevated baseline creatinine (OR 2.80; 95% CI 1.63- 4.80) or troponin (OR 1.89; 95% 1.03-3.47), baseline lymphopenia (OR 2.19; 95% CI 1.61-2.97), presence of infiltrate by chest imaging (OR 3.16; 95% CI 1.96-5.10), and high SARS-CoV2 viral load (OR 1.53; 95% CI 1.17-2.00). Fatal cases had the lowest ratio of SARS-CoV-2 antibody to viral load levels compared to other trajectories over time (p=0.001). 589 survivors (51%) completed at least one survey at follow-up with 305 (52%) having at least one symptom consistent with PASC, most commonly dyspnea (56% among symptomatic patients). Female sex was the only associated risk factor for PASC. INTERPRETATION: Integration of PCR cycle threshold, and antibody values with demographics, comorbidities, and laboratory/radiographic findings identified risk factors for 28-day outcome severity, though only female sex was associated with PASC. Longitudinal clinical phenotyping offers important insights, and provides a framework for immunophenotyping for acute and long COVID-19. FUNDING: NIH.
