Identification of Fatigue Subtypes and Their Correlates in Prevalent Heart Failure: A Secondary Analysis of the Atherosclerosis Risk in Communities Study.

BACKGROUND: Among patients with heart failure (HF), fatigue is common and linked to quality of life and functional status. Fatigue is hypothesized to manifest as multiple types, with general and exertional components. Unique subtypes of fatigue in HF may require differential assessment and treatment to improve outcomes. We conducted this study to identify fatigue subtypes in persons with prevalent HF in the ARIC study (Atherosclerosis Risk in Communities) and describe the distribution of characteristics across subtypes. METHODS: We performed a cross-sectional analysis of 1065 participants with prevalent HF at ARIC visit 5 (2011-2013). We measured exertional fatigue using the Modified Medical Research Council Breathlessness scale and general fatigue using the Patient Reported Outcomes Measurement Information System fatigue scale. We used latent class analysis to identify subtypes of fatigue. Number of classes was determined using model fit statistics, and classes were interpreted and assigned fatigue severity rating based on the conditional probability of endorsing survey items given class. We compared characteristics across classes using multinomial regression. RESULTS: Overall, participants were 54% female and 38% Black with a mean age of 77. We identified 4 latent classes (fatigue subtypes): (1) high general/high exertional fatigue (18%), (2) high general/low exertional fatigue (27%), (3) moderate general/moderate exertional fatigue (20%), and (4) low/no general and exertional fatigue (35%). Female sex, Black race, lower education level, higher body mass index, increased depressive symptoms, and higher prevalence of diabetes were associated with higher levels of general and exertional fatigue. CONCLUSIONS: We identified unique subtypes of fatigue in patients with HF who have not been previously described. Within subtype, general and exertional fatigue were mostly concordant in severity, and exertional fatigue only occurred in conjunction with general fatigue, not alone. Further understanding these fatigue types and their relationships to outcomes may enhance our understanding of the symptom experience and inform prognostication and secondary prevention efforts for persons with HF.

Long-Term Effects of Incentives for HIV Viral Suppression: A Randomized Clinical Trial.

Achieving viral suppression in people living with HIV improves their quality of life and can help end the HIV/AIDS epidemic. However, few interventions have successfully promoted HIV viral suppression. The purpose of this study was to evaluate the long-term effectiveness of financial incentives for viral suppression in people living with HIV. People living with a detectable HIV viral load (≥ 200 copies/mL) were randomly assigned to Usual Care (n = 50) or Incentive (n = 52) groups. Incentive participants earned up to $10 per day for providing blood samples with an undetectable or reduced viral load. During the 2-year intervention period, the percentage of blood samples with a suppressed viral load was significantly higher among Incentive participants (70%) than Usual Care participants (43%) (OR = 7.1, 95% CI 2.7 to 18.8, p < .001). This effect did not maintain after incentives were discontinued. These findings suggest that frequent delivery of large-magnitude financial incentives for viral suppression can produce large and long-lasting improvements in viral load in people living with HIV.

Comparative assessment of Alzheimer's disease-related biomarkers in plasma and neuron-derived extracellular vesicles: a nested case-control study.

Introduction: Alzheimer's disease (AD) is currently defined according to biomarkers reflecting the core underlying neuropathological processes: Aß deposition, Tau, and neurodegeneration (ATN). The soluble phase of plasma and plasma neuron-derived extracellular vesicles (NDEVs) are increasingly being investigated as sources of biomarkers. The aim of this study was to examine the comparative biomarker potential of these two biofluids, as well as the association between respective biomarkers. Methods: We retrospectively identified three distinct diagnostic groups of 44 individuals who provided samples at baseline and at a mean of 3.1 years later; 14 were cognitively unimpaired at baseline and remained so (NRM-NRM), 13 had amnestic MCI that progressed to AD dementia (MCI-DEM) and 17 had AD dementia at both timepoints (DEM-DEM). Plasma NDEVs were isolated by immunoaffinity capture targeting the neuronal markers L1CAM, GAP43, and NLGN3. In both plasma and NDEVs, we assessed ATN biomarkers (Aß42, Aß40, total Tau, P181-Tau) alongside several other exploratory markers. Results: The Aß42/Aß40 ratio in plasma and NDEVs was lower in MCI-DEM than NRM-NRM at baseline and its levels in NDEVs decreased over time in all three groups. Similarly, plasma and NDEV-associated Aß42 was lower in MCI-DEM compared to NRM-NRM at baseline and its levels in plasma decreased over time in DEM-DEM. For NDEV-associated proBDNF, compared to NRM-NRM, its levels were lower in MCI-DEM and DEM-DEM at baseline, and they decreased over time in the latter group. No group differences were found for other exploratory markers. NDEV-associated Aß42/Aß40 ratio and proBDNF achieved the highest areas under the curve (AUCs) for discriminating between diagnostic groups, while proBDNF was positively associated with Mini-Mental State Examination (MMSE) score. No associations were found between the two biofluids for any assessed marker. Discussion: The soluble phase of plasma and plasma NDEVs demonstrate distinct biomarker profiles both at a single time point and longitudinally. The lack of association between plasma and NDEV measures indicates that the two types of biofluids demonstrate distinct biomarker signatures that may be attributable to being derived through different biological processes. NDEV-associated proBDNF may be a useful biomarker for AD diagnosis and monitoring.

Abstinence-contingent wage supplements for adults experiencing homelessness and alcohol use disorder: A randomized clinical trial.

This study evaluated the effectiveness of abstinence-contingent wage supplements in promoting alcohol abstinence and employment in adults experiencing homelessness and alcohol use disorder. A randomized clinical trial was conducted from 2019 to 2022. After a 1-month Induction period, 119 participants were randomly assigned to a Usual Care Control group (n = 57) or an Abstinence-Contingent Wage Supplement group (n = 62). Usual Care participants were offered counseling and referrals to employment and treatment programs. Abstinence-Contingent Wage Supplement participants could earn stipends for working with an employment specialist and wage supplements for working in a community job but had to maintain abstinence from alcohol as determined by transdermal alcohol concentration monitoring devices to maximize pay. Abstinence-Contingent Wage Supplement participants reported significantly higher rates of alcohol abstinence than Usual Care participants during the 6-month intervention (82.8% vs. 60.2% of months, OR = 3.4, 95% CI 1.8 to 6.3, p < .001). Abstinence-Contingent Wage Supplement participants were also significantly more likely to obtain employment (51.3% vs. 31.6% of months, OR = 2.6, 95% CI 1.5 to 4.4, p < .001) and live out of poverty (38.2% vs. 16.7% of months, OR = 3.7, 95% CI 2.0 to 7.1, p < .001) than Usual Care participants. These findings suggest that Abstinence-Contingent Wage Supplements can promote alcohol abstinence and employment in adults experiencing homelessness and alcohol use disorder.

The associations between unmet needs with protective factors, risk factors and outcomes among care partners of community-dwelling persons living with dementia.

OBJECTIVES: Describe the prevalence and types of unmet needs among community-dwelling dementia care partners (CPs) and determine associations between unmet needs with protective factors, risk factors and outcomes. METHOD: A cross-sectional analysis of 638 racially and cognitively diverse community-dwelling persons living with dementia (PLWD) and their CPs participating in a comprehensive in-home assessment of dementia-related needs. Unmet CP needs (19 items, 6 domains) were rated by a clinician using the Johns Hopkins Dementia Care Needs Assessment (JHDCNA). Multivariate linear regression models were used to examine associations between total percent unmet CP needs with demographic, protective and risk factors. RESULTS: Nearly all CPs had at least one unmet need (99.53%), with a mean of 5.7 (±2.6). The most common domains with ≥1 unmet need were memory disorder education, care skills and knowledge of resources (98%), legal issues/concerns (73.8%), CP mental health (44.6%) and access to informal support (42.7%). Adjusted multivariate models suggest the strongest consistent predictive factors relate to informal emotional support, CP physical health, use or difficulty getting formal services/supports (both for CPs and PLWD), and CP time spent with PLWD. Greater levels of unmet needs were associated with worse PLWD outcomes and CP outcomes, after adjusting for demographics. CONCLUSIONS: CPs have high rates of diverse, but modifiable unmet needs. Data suggest optimal approaches to dementia care should take a family-centered home-based approach that includes routine CP needs assessment, offer targeted interventions that include both traditional medical supports as well as strategies to increase and leverage informal social networks, and ones that can bridge and coordinate medical with non-medical supports. These findings can be used to inform new approaches to support CPs, improve PLWD and CP outcomes, and target groups most at risk for inequities.

'Anxious fluctuators' a subgroup of Parkinson's disease with high anxiety and problematic on-off fluctuations.

Anxiety that occurs in association with on-off dopamine medication fluctuations is a major cause of distress, dysfunction, and lower quality of life in people with Parkinson's disease (PD). However, the association between anxiety and on-off fluctuations is poorly understood and it is difficult to predict which patients will suffer from this atypical form of anxiety. To understand whether fluctuating anxiety in PD exists as part of an endophenotype that is associated with other signs or symptoms, we prospectively assessed the change in anxiety and a battery of clinical variables when transitioning from the off-dopamine medication state to the on state in 200 people with PD. We performed latent profile analysis with observed variables as latent profile indicators measuring the on-off-state difference in anxiety, depression, motor function, daily functioning, and the wearing off questionnaire 19 item scale (WOQ-19) in order to model unobserved (i.e., latent) profiles. A two-class model produced the best fit. The majority of participants, 69%, were categorized as having a 'typical on-off response' compared to a second profile constituting 31% of the sample who experienced a worsening in anxiety in the off state that was three times that of other participants. This profile referred to as "anxious fluctuators" had a Hamilton Anxiety Rating Scale change between the off and on medication state of 10.22(32.85) compared to 3.27 (7.62), higher depression scores, greater disability and was less likely to improve on select WOQ-19 items when in the on-state. Anxious fluctuators were more likely to be male and have a family history of anxiety disorder. Given the adverse impact of this profile we believe it may be important to distinguish patients with a typical on-off response from those with this more problematic course of fluctuations.

Graphical methods for understanding changes in states: Understanding medication use pathways.

OBJECTIVES: As epidemiological studies become longer and larger, the field needs novel graphical methods to visualize complex longitudinal data. The aim of this study was to present the Slinkyplot, a longitudinal crosstabulation, to illustrate patterns of antidepressant use in a large prospective cohort of older adults with mild cognitive impairment. METHODS: Data from the National Alzheimer's Coordinating Center are used to track switches between different states and types of antidepressant use. A Slinkyplot is populated with rows representing the state of medication use at each timepoint and columns representing the state at each subsequent visit. RESULTS: The constructed Slinkyplots display the common practice of switching on and off different antidepressants over time, with citalopram, sertraline, and bupropion most commonly used followed by switching to another SSRI or SNRI as second-line treatment. CONCLUSIONS: Slinkyplots are an innovative graphical means of visualizing complex patterns of transitions between different states over time for large longitudinal studies.

Prevalence and Correlates of Depressive Symptoms Within 6 Months After First-Time Mild Traumatic Brain Injury.

OBJECTIVE: Depressive symptoms are among the most common neuropsychiatric sequelae of mild traumatic brain injury (mTBI). Very few studies have compared correlates of depressive symptoms within the first 6 months of injury in cohorts experiencing their first TBI. The authors investigated whether the correlates of depressive symptoms (being female, older, lower education, having brain lesions, experiencing worse postconcussive symptoms, and incomplete functional recovery) that have been established in populations with moderate to severe TBI were the same for individuals with first-time mTBI within the first 6 months of recovery. METHODS: Two hundred seventeen individuals with first-time mTBI were divided into subgroups-new-onset depressive symptoms, recurrent depressive symptoms, prior depression history only, and never depressed-and compared on clinical and demographic variables and the presence of postconcussive symptoms and functional recovery at 3 and 6 months. RESULTS: New-onset depressive symptoms developed in 12% of the cohort, whereas 11% of the cohort had recurrent depressive symptoms. Both depressive symptoms groups were more likely to comprise women and persons of color and were at higher risk for clinically significant postconcussive symptoms and incomplete functional recovery for the first 6 months postinjury. CONCLUSIONS: Presence of depressive symptoms after first-time mTBI was associated with persistent postconcussive symptoms and incomplete functional recovery in the first 6 months. Adding to the existing literature, these findings identified correlates of depressive symptom development and poor outcomes after mTBI, thus providing further evidence that mTBI may produce persistent symptoms and functional limitations that warrant clinical attention.

Neuronal-Derived EV Biomarkers Track Cognitive Decline in Alzheimer's Disease.

The hallmarks of Alzheimer's disease (AD) pathology are senile plaques containing amyloid-beta (Aß) and neurofibrillary tangles containing hyperphosphorylated tau. Additional pathologies often co-exist, whereas multiple pathogenic mechanisms are involved in AD, especially synaptic degeneration, which necessitate the need for synaptic integrity-related biomarkers alongside Aß- and tau-related biomarkers. Plasma neuron-derived Extracellular Vesicles EVs (NDEVs) provide biomarkers related to Aß and tau and synaptic degeneration. Here, to further establish the latter as a "liquid biopsy" for AD, we examined their relationship with ante-mortem cognition in pathologically-confirmed AD cases. We immunoprecipitated NDEVs by targeting neuronal marker L1CAM from ante-mortem plasma samples from 61 autopsy-confirmed cases of pure AD or AD with additional pathologies and measured Aß42, p181-Tau, total Tau, synaptophysin, synaptopodin and three canonical EV markers, CD63, CD81 and CD9. Higher NDEV Aß42 levels were consistently associated with better cognitive status, memory, fluency, working memory and executive function. Higher levels of NDEV synaptic integrity-related biomarkers were associated with better performance on executive function tasks. Our findings motivate the hypothesis that releasing Aß42-laden NDEVs may be an adaptive mechanism in AD.

Abstinence-contingent wage supplements to promote drug abstinence and employment: Post-intervention outcomes.

BACKGROUND: Substance use disorder, unemployment, and poverty are interrelated problems that have not been addressed adequately by existing interventions. This study evaluated post-intervention effects of abstinence-contingent wage supplements on drug abstinence and employment. METHODS: Unemployed adults enrolled in opioid agonist treatment were randomly assigned to an abstinence-contingent wage supplement group (n = 44) or a usual care control group (n = 47). All participants could work with an employment specialist throughout a 12-month intervention period. Those in the abstinence-contingent wage supplement group earned stipends for working with the employment specialist and, after gaining employment, abstinence-contingent wage supplements for working in their community job but had to provide opiate- and cocaine-negative urine samples to maximize pay. To assess post-intervention effects of abstinence-contingent wage supplements and compare those effects to during-intervention effects, we analyzed urine samples and self-reports every 3 months during the 12-month intervention and the 12-month post-intervention period. RESULTS: During the intervention, abstinence-contingent wage supplement participants provided significantly more opiate- and cocaine-negative urine samples than usual care control participants; abstinence-contingent wage supplement participants were also significantly more likely to become employed and live out of poverty than usual care participants during intervention. During the post-intervention period, the abstinence-contingent wage supplement and usual care control groups had similar rates of drug abstinence, similar levels of employment, and similar proportions living out of poverty. CONCLUSIONS: Long-term delivery of abstinence-contingent wage supplements can promote drug abstinence and employment, but many patients relapse to drug use and cease employment when wage supplements are discontinued.

Assumptions Not Often Assessed or Satisfied in Published Mediation Analyses in Psychology and Psychiatry.

Mediation analysis aims to investigate the mechanisms of action behind the effects of interventions or treatments. Given the history and common use of mediation in mental health research, we conducted this review to understand how mediation analysis is implemented in psychology and psychiatry and whether analyses adhere to, address, or justify the key underlying assumptions of their approaches. All articles (n = 206) were from top academic psychiatry or psychology journals in the PsycInfo database and were published in English from 2013 to 2018. Information extracted from each article related to study design, covariates adjusted for in the analysis, temporal ordering of variables, and the specific method used to perform the mediation analysis. In most studies, underlying assumptions were not adhered to. Only approximately 20% of articles had full temporal ordering of exposure, mediator, and outcome. Confounding of the exposure-mediator and/or mediator-outcome relationships was controlled for in fewer than half of the studies. In almost none of the articles were the underlying assumptions of their approaches discussed or causal mediation methods used. These results provide insights to how methodologists should aim to communicate methods, and motivation for more outreach to the research community on best practices for mediation analysis.

Functional Disabilities and Psychiatric Symptoms in Primary Progressive Aphasia.

OBJECTIVE: The aims of this study are to describe the chronology of functional disabilities in primary progressive aphasia (PPA), and to examine associations between psychiatric comorbidities and functional disabilities. METHODS: We conducted a retrospective data analysis using subjects enrolled at Alzheimer's Disease Research Centers between 2005 and 2019. Data were obtained from the National Alzheimer's Coordinating Center database. We included subjects whose primary diagnosis was PPA. Functional status was coded as a binary variable for the following functions: ambulation, transaction skills, verbal communication, meal preparation, and self-care. Behavioral data derived from the Neuropsychiatric Inventory Questionnaire. Descriptive statistics and cox proportional hazard analyses were used to characterize the emergence of disabilities and their association with psychiatric comorbidities. RESULTS: Data included 91 subjects with a clinical dementia rating scale of zero at baseline. At the initial visit, no individuals had impairments in self-care, while 7% had impairments in transactions, 3% in ambulation, and 2% in meal preparation. Ninety-three percent had language impairments at the onset of the study, and all by visit 4. By visit 5, 41% of patients had impairments in ambulation and in self-care, 49% were impaired in meal preparation and 70% had impairment in transactions. The presence of anxiety, depression, sleep disturbance and psychosis were all significantly associated with an increased risk for multiple functional disabilities. CONCLUSION: These findings provide clinicians with guidance for forecasting disabilities and targeting interventions in PPA.

Technology-assisted opioid education for out-of-treatment adults with opioid use disorder.

OBJECTIVE: To evaluate the feasibility and potential efficacy of a technology-assisted education program in teaching adults at a high risk of opioid overdose about opioids; opioid overdose; and opioid use disorder medications. METHOD: A within-subject, repeated-measures design was used to evaluate effects of the novel technology-assisted education program. Participants (N = 40) were out-of-treatment adults with opioid use disorder, recruited in Baltimore, Maryland from May 2019 to January 2020. The education program was self-paced and contained three courses. Each course presented information and required answers to multiple-choice questions. The education program was evaluated using a 50-item test, delivered before and after participants completed each course. Tests were divided into three subtests that contained questions from each course. We measured accuracy on each subtest before and after completion of each course and used a mixed-effects model to analyze changes in accuracy across tests. RESULTS: The technology-assisted education program required a median time of 91 min of activity to complete. Most participants completed the program in a single day. Accuracy on each subtest increased only after completion of the course that corresponded to that subtest, and learning comparisons were significant at the p < .001 level for all subtests. Accuracy on each subtest was unchanged before completion of the relevant course, and increases in accuracy were retained across subsequent tests. Learning occurred similarly independent of participant education, employment, and poverty. CONCLUSIONS: Technology-assisted education programs can provide at-risk adults with access to effective education on opioids, opioid overdose, and opioid use disorder medications.

Psychosocial Interventions to Promote Undetectable HIV Viral Loads: A Systematic Review of Randomized Clinical Trials.

Suppressing HIV viral loads to undetectable levels is essential for ending the HIV/AIDS epidemic. We evaluated randomized controlled trials aimed to increase antiretroviral medication adherence and promote undetectable viral loads among people living with HIV through November 22, 2019. We extracted data from 51 eligible interventions and analyzed the results using random effects models to compare intervention effects between groups within each intervention and across interventions. We also evaluated the relation between publication date and treatment effects. Only five interventions increased undetectable viral loads significantly. As a whole, the analyzed interventions were superior to Standard of Care in promoting undetectable viral loads. Interventions published more recently were not more effective in promoting undetectable viral loads. No treatment category consistently produced significant increases in undetectable viral loads. To end the HIV/AIDS epidemic, we should use interventions that can suppress HIV viral loads to undetectable levels.

Study rationale and baseline data for pilot trial of dronabinol adjunctive treatment of agitation in Alzheimer's dementia (THC-AD).

Agitation is a common complication of Alzheimer's dementia (Agit-AD) associated with substantial morbidity, high healthcare service utilization, and adverse emotional and physical impact on care partners. There are currently no FDA-approved pharmacological treatments for Agit-AD. We present the study design and baseline data for an ongoing multisite, three-week, double-blind, placebo-controlled, randomized clinical trial of dronabinol (synthetic tetrahydrocannabinol [THC]), titrated to a dose of 10 mg daily, in 80 participants to examine the safety and efficacy of dronabinol as an adjunctive treatment for Agit-AD. Preliminary findings for 44 participants enrolled thus far show a predominately female, white sample with advanced cognitive impairment (Mini Mental Status Examination mean 7.8) and agitation (Neuropsychiatric Inventory-Clinician Agitation subscale mean 14.1). Adjustments to study design in light of the COVID-19 pandemic are described. Findings from this study will provide guidance for the clinical utility of dronabinol for Agit-AD. ClinicalTrials.gov Identifier: NCT02792257.

Remotely delivered incentives to promote buprenorphine treatment engagement in out-of-treatment adults with opioid use disorder.

BACKGROUND: Opioid overdose remains a leading cause of death. Office-based buprenorphine could expand access to treatment to the many opioid users who are not in treatment and who are at risk for opioid overdose. However, many people in need of buprenorphine treatment do not enroll in treatment. This randomized pilot trial evaluated efficacy of a remotely delivered incentive intervention in promoting engagement in buprenorphine treatment in out-of-treatment adults with opioid use disorder. METHODS: Participants (N = 41) were offered referrals to buprenorphine treatment and randomly assigned to Control or Incentive groups for 6 months. Incentive participants were offered incentives for enrolling in buprenorphine treatment, verified by providing documentation showing that they received a buprenorphine prescription, and providing videos taking daily buprenorphine doses. Participants used a smartphone application to record and submit a video of their buprenorphine prescription and daily buprenorphine administration. Incentive earnings were added remotely to reloadable credit cards. RESULTS: Incentive participants were significantly more likely to enroll in treatment compared to control participants (71.4 % versus 30.0 % of participants; OR [95 % CI]: 6.24 [1.46-26.72], p = .014). Few participants in either group adhered to buprenorphine treatment, and the two groups continued to use opioids, including fentanyl at high and comparable rates. The two groups did not differ in the percentage of urine samples that were positive for buprenorphine, opiates, fentanyl, or methadone at monthly assessments conducted during the 6-month intervention. CONCLUSIONS: Remotely delivered incentives can connect out-of-treatment adults with opioid use disorder to treatment, but additional supports are needed to promote buprenorphine adherence.

Open science datasets from PREVENT-AD, a longitudinal cohort of pre-symptomatic Alzheimer's disease.

To move Alzheimer Disease (AD) research forward it is essential to collect data from large cohorts, but also make such data available to the global research community. We describe the creation of an open science dataset from the PREVENT-AD (PResymptomatic EValuation of Experimental or Novel Treatments for AD) cohort, composed of cognitively unimpaired older individuals with a parental or multiple-sibling history of AD. From 2011 to 2017, 386 participants were enrolled (mean age 63 years old ± 5) for sustained investigation among whom 349 have retrospectively agreed to share their data openly. Repositories are findable through the unified interface of the Canadian Open Neuroscience Platform and contain up to five years of longitudinal imaging data, cerebral fluid biochemistry, neurosensory capacities, cognitive, genetic, and medical information. Imaging data can be accessed openly at https://openpreventad.loris.ca while most of the other information, sensitive by nature, is accessible by qualified researchers at https://registeredpreventad.loris.ca. In addition to being a living resource for continued data acquisition, PREVENT-AD offers opportunities to facilitate understanding of AD pathogenesis.

Bodily pain in survivors of acute respiratory distress syndrome: A 1-year longitudinal follow-up study.

PURPOSE: Acute respiratory distress syndrome (ARDS) survivors frequently experience bodily pain during recovery after the intensive care unit. Longitudinal course, risk factors and associations with physical and neuropsychological health is lacking. METHODS: We collected self-reported pain using the Short Form-36 Bodily Pain (SF-36 BP) scale, normalized for sex and age (range: 0-100; higher score = less pain), along with physical and mental health measures in a multi-center, prospective cohort of 826 ARDS survivors at 6- and 12-month follow-up. We examined baseline and ICU variables' associations with pain via separate unadjusted regression models. RESULTS: Pain prevalence (SF-36 BP ≤40) was 45% and 42% at 6 and 12 months, respectively. Among 706 patients with both 6- and 12-month data, 34% reported pain at both timepoints. Pre-ARDS employment was associated with less pain at 6-months (mean difference (standard error), 5.7 (0.9), p < 0.001) and 12-months (6.3 (0.9), p < 0.001); smoking history was associated with greater pain (-5.0 (0.9), p < 0.001, and - 5.4 (1.0), p < 0.001, respectively). In-ICU opioid use was associated with greater pain (-6.3 (2.7), p = 0.02, and - 7.3 (2.8), p = 0.01, respectively). At 6 months, 174 (22%) patients reported co-occurring pain, depression and anxiety, and 227 (33%) reported co-occurring pain and impaired physical function. CONCLUSION: Nearly half of ARDS survivors reported bodily pain at 6- and 12-month follow-up; one-third reported pain at both time points. Pre-ARDS unemployment, smoking history, and in-ICU opioid use may identify patients who report greater pain during recovery. Given its frequent co-occurrence, clinicians should manage both physical and neuropsychological issues when pain is reported.

Development and psychometric testing of the FLW-MSC scale for measuring frontline worker multisectoral collaboration in rural India.

OBJECTIVES: Multisectoral collaboration (MSC) is widely recognised as a critical aspect of policies, programmes and interventions addressing complex public health issues, yet it is undertheorised and difficult to measure. Limited understanding of the intermediate steps linking MSC formation to intended health outcomes leaves a substantial knowledge gap about the types of strategies that may be most effective in making such collaborations successful. This paper, which reports the quantitative strand of a broader mixed-methods study, takes a step toward filling in this 'missing middle' of MSC evaluation by developing and testing the FLW-MSC scale, an instrument to assess collaboration among the frontline workers of one of India's largest and most widely known MSCs: the Integrated Child Development Services (ICDS) scheme. DESIGN: This study involved development, field-testing and psychometric testing of an 18-item, Likert-type frontline worker collaboration scale, including internal consistency, construct validity and criterion validity. SETTING: Village-level primary healthcare in rural Uttar Pradesh, India. PARTICIPANTS: 281 anganwadi workers, 266 accredited social health activists and 124 auxiliary nurse midwives selected based on random sampling of anganwadi catchment areas from 346 gram panchayats (GPs), including 173 intervention GPs and 173 pair-matched control GPs from a parent evaluation study. RESULTS: Results support the scale's internal consistency (ordinal α=0.92-0.95), construct validity (reasonable exploratory factor analysis model fit for five of the six dyadic relationships Tucker-Lewis Index=0.84-0.88; Root Mean Squared Error of Approximation=0.09-0.11), and criterion validity (regression of collaboration score on an information-sharing indicator ß=3.528; p=0.006). CONCLUSIONS: The scale may be useful for ICDS managers to detect and address poor collaboration as the Indian government redoubles its efforts to strengthen and monitor MSC, or 'convergence', with important implications for the critical priority of child development. Further, the FLW-MSC scale may be adapted for measuring frontline worker collaboration across sectors in many other scenarios and low/middle-income country contexts.

Reducing Risky Drug Use Behaviors by Enrolling Syringe Exchange Registrants in Methadone Maintenance.

BACKGROUND: Referral of syringe exchange registrants with opioid use disorder to agonist treatment provides a pathway to further reduce drug use risk behaviors. Objective: This study evaluates the drug use risk reduction benefits of enrolling syringe exchange registrants in methadone maintenance, and the impact of continued illicit drug use on risk reduction. Method: Baltimore Needle Exchange Program (BNEP) registrants (n = 210) participated in a parent study evaluating treatment initiation strategies for methadone maintenance and were followed for six months. The Risk Assessment Battery (RAB; Metzger, 1993) was administered monthly to evaluate drug use risks; urinalysis testing was conducted weekly. Results: Treatment enrollment reduced drug use risk behaviors, and longer treatment episodes resulted in additional, though modest, risk reduction. Use of opioids or cocaine in treatment diminished risk-reduction benefits, though drug use risks declined over time and remained well below baseline levels. Conclusions: These findings demonstrate that methadone maintenance enhances the well-known risk-reduction benefits of syringe exchange participation. Improving coordination between syringe exchanges and treatment facilities may enhance the public health.
