RESUMEN
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.

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.

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.

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.

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.

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.

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.

OBJECTIVES: Postoperative delirium, associated with negative consequences including longer hospital stays and worse cognitive and physical outcomes, is frequently accompanied by sleep-wake disturbance. Our objective was to evaluate the efficacy and short-term safety of ramelteon, a melatonin receptor agonist, for the prevention of postoperative delirium in older patients undergoing orthopedic surgery. DESIGN: A quadruple-masked randomized placebo-controlled trial (Clinical Trials.gov NCT02324153) conducted from March 2017 to June 2019. SETTING: Tertiary academic medical center. PARTICIPANTS: Patients aged 65 years or older, undergoing elective primary or revision hip or knee replacement. INTERVENTION: Ramelteon (8 mg) or placebo MEASUREMENTS: Eighty participants were randomized to an oral gel cap of ramelteon or placebo for 3 consecutive nights starting the night before surgery. Trained research staff conducted delirium assessments for 3 consecutive days starting on postoperative day (POD) 0, after recovery from anesthesia, and on to POD2. A delirium diagnosis was based upon DSM-5 criteria determined by expert panel consensus. RESULTS: Of 80 participants, five withdrew consent (one placebo, four ramelteon) and four were excluded (four ramelteon) after randomization. Delirium incidence during the 2 days following surgery was 7% (5 of 71) with no difference between the ramelteon versus placebo: 9% (3 of 33) and 5% (2 of 38), respectively. The adjusted odds ratio for postoperative delirium as a function of assignment to the ramelteon treatment arm was 1.28 (95% confidence interval: 0.21-7.93; z-value 0.27; p-valueâ¯=â¯0.79). Adverse events were similar between the two groups. CONCLUSION: In older patients undergoing elective primary or revision hip or knee replacement, ramelteon was not efficacious in preventing postoperative delirium.

OBJECTIVES: While there is growing evidence of an association between depressive symptoms and postoperative delirium, the underlying pathophysiological mechanisms remain unknown. The goal of this study was to explore the association between depression and postoperative delirium in hip fracture patients, and to examine Alzheimer's disease (AD) pathology as a potential underlying mechanism linking depressive symptoms and delirium. METHODS: Patients 65 years old or older (Nâ¯=â¯199) who were undergoing hip fracture repair and enrolled in the study "A Strategy to Reduce the Incidence of Postoperative Delirium in Elderly Patients" completed the 15-item Geriatric Depression Scale (GDS-15) preoperatively. Cerebrospinal fluid (CSF) was obtained during spinal anesthesia and assayed for amyloid-beta (Aß) 40, 42, total tau (t-tau), and phosphorylated tau (p-tau)181. RESULTS: For every one point increase in GDS-15, there was a 13% increase in odds of postoperative delirium, adjusted for baseline cognition (MMSE), age, sex, race, education and CSF AD biomarkers (ORâ¯=â¯1.13, 95%CIâ¯=â¯1.02-1.25). Both CSF Aß42/t-tau (ßâ¯=â¯-1.52, 95%CIâ¯=â¯-2.1 to -0.05) and Aß42/p-tau181 (ßâ¯=â¯-0.29, 95%CI = -0.48 to -0.09) were inversely associated with higher GDS-15 scores, where lower ratios indicate greater AD pathology. In an analysis to identify the strongest predictors of delirium out of 18 variables, GDS-15 had the highest classification accuracy for postoperative delirium and was a stronger predictor of delirium than both cognition and AD biomarkers. CONCLUSIONS: In older adults undergoing hip fracture repair, depressive symptoms were associated with underlying AD pathology and postoperative delirium. Mild baseline depressive symptoms were the strongest predictor of postoperative delirium, and may represent a dementia prodrome.

OBJECTIVES: To examine trajectories of depression and apathy over a 5-year follow-up period in (prodromal) Alzheimer's disease (AD), and to relate these trajectories to AD biomarkers. METHODS: The trajectories of depression and apathy (measured with the Neuropsychiatric Inventory or its questionnaire) were separately modeled using growth mixture models for two cohorts (National Alzheimer's Coordinating Center, NACC, n = 22 760 and Alzheimer's Disease Neuroimaging Initiative, ADNI, n = 1 733). The trajectories in ADNI were associated with baseline CSF AD biomarkers (Aß42, t-tau, and p-tau) using bias-corrected multinomial logistic regression. RESULTS: Multiple classes were identified, with the largest classes having no symptoms over time. Lower Aß42 and higher tau (ie, more AD pathology) was associated with increased probability of depression and apathy over time, compared to classes without symptoms. Lower Aß42 (but not tau) was associated with a steep increase of apathy, whereas higher tau (but not Aß42 ) was associated with a steep decrease of apathy. DISCUSSION: The trajectories of depression and apathy in individuals on the AD spectrum are associated with AD biomarkers.

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.
RESUMEN
Precision medicine, also known as personalized medicine, is concerned with finding the right treatment for the right patient at the right time. It is a way of thinking focused on parsing heterogeneity ultimately down to the level of the individual. Its main mission is to identify characteristics of heterogeneous clinical conditions so as to target tailored therapies to individuals. Precision Medicine however is not an agnostic collection of all manner of clinical, genetic and other biologic data in select cohorts. This is an important point. Simply collecting as much information as possible on individuals without applying this way of thinking should not be considered Precision Medicine.

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.

INTRODUCTION: There has been considerable progress in identifying early cognitive and biomarker predictors of Alzheimer's disease (AD). Neuropsychiatric symptoms (NPS) are common in AD and appear to predict progression after the onset of mild cognitive impairment or dementia. OBJECTIVES: The objective of the study is to examine the relationship between NPS in clinically normal older adults and subsequent cognitive decline in a population-based sample. METHODS: The Cache County Study on Memory in Aging consists of a population-based sample of 5,092 older adults. We identified 470 clinically normal adults who were followed for an average period of 5.73 years. NPS were evaluated at the baseline clinical assessment using the Neuropsychiatric Inventory (NPI). NPI domain scores were quantified as the product of frequency X severity in individual NPI domains, and then summed for the NPI-Total. Neuropsychological measures were collected at baseline and at each subsequent follow-up wave. Linear mixed-effects models assessed the association of NPI-Total, NPI-Depression, and NPI-Anxiety scores (obtained at baseline) on longitudinal change in neuropsychological performance, controlling for age, sex, and education. RESULTS: Baseline NPI-Total score was associated with a more rapid rate of decline in word list memory, praxis recall, and animal fluency. Baseline NPI-Depression was not associated with later decline on any of the cognitive tests, while baseline NPI-Anxiety was associated with decline in Symbol Digit Modality. CONCLUSION: In conclusion, among clinically normal older adults derived from this population-based study, total burden of NPS was associated with longitudinal cognitive decline. These results add to the evidence that NPS are risk factors for or clinical indicators of preclinical dementia syndrome. Our study was an exploratory study and we did not control for multiple comparisons.

OBJECTIVE: The authors tested the hypothesis that a combination of loss of consciousness (LOC) and altered mental state (AMS) predicts the highest risk of incomplete functional recovery within 6 months after mild traumatic brain injury (mTBI), compared with either condition alone, and that LOC alone is more strongly associated with incomplete recovery, compared with AMS alone. METHODS: Data were analyzed from 407 patients with mTBI from Head injury Serum Markers for Assessing Response to Trauma (HeadSMART), a prospective cohort study of TBI patients presenting to two urban emergency departments. Four patient subgroups were constructed based on information documented at the time of injury: neither LOC nor AMS, LOC only, AMS only, and both. Logistic regression models assessed LOC and AMS as predictors of functional recovery at 1, 3, and 6 months. RESULTS: A gradient of risk of incomplete functional recovery at 1, 3, and 6 months postinjury was noted, moving from neither LOC nor AMS, to LOC or AMS alone, to both. LOC was associated with incomplete functional recovery at 1 and 3 months (odds ratio=2.17, SE=0.46, p<0.001; and odds ratio=1.80, SE=0.40, p=0.008, respectively). AMS was associated with incomplete functional recovery at 1 month only (odds ratio=1.77, SE=0.37 p=0.007). No association was found between AMS and functional recovery in patients with no LOC. Neither LOC nor AMS was predictive of functional recovery at later times. CONCLUSIONS: These findings highlight the need to include symptom-focused clinical variables that pertain to the injury itself when assessing who might be at highest risk of incomplete functional recovery post-mTBI.

RESUMEN
BACKGROUND: Wernicke-Korsakoff Syndrome (WKS) resulting from thiamine deficiency is classically defined as including encephalopathy, ataxia, and ophthalmoplegia. Only 16% of autopsy-confirmed patients with WKS exhibit all three signs. Caine-positive WKS criteria include two or more of the following: nutritional deficiency, delirium or mild memory impairment, cerebellar dysfunction/ataxia, and oculomotor abnormalities. OBJECTIVE: We describe Caine-positive WKS prevalence among psychiatric inpatients and compare pretreatment-versus-posttreatment neurocognitive improvement to an unaffected group. METHODS: This 6-month quality-improvement evaluation included two-stage screening for Caine-positive WKS, administering high-dose intravenous thiamine (day 1: 1200 mg; days 2-4: 200 mg) with reexamination on day 5. We used descriptive statistics and fitted random effects models to examine rate-of-change differences in pre-/posttreatment Montreal Cognitive Assessment (MoCA), delayed 5-item recall, and gait/coordination scores between treated Caine-positive patients with WKS and untreated Caine-negative patients. RESULTS: Of 262 patients, 32 (12%) had Caine-positive WKS; 17 (53%) used alcohol currently. Treated Caine-positive WKS (n = 26) versus Caine-negative comparison (n = 34) before and after treatment observed a mean change (standard deviation) in the MoCA score of 3.6 (2.5) versus 1.8 (2.5) (P < 0.01); 5-item recall: 1.8 (1.4) versus 0.5 (1.4) (P < 0.001); gait/coordination scores: -0.6 (1.2) versus -0.1 (0.6) (P < 0.001). Oculomotor abnormalities were infrequent (n = 4 in Caine-positive WKS, n = 2 in Caine-negative comparison groups). CONCLUSIONS: Caine-positive WKS prevalence among psychiatric inpatients was 12%; only half used alcohol. Patients treated with high-dose thiamine demonstrated clinically significant neurocognitive improvement.

BACKGROUND: Alcohol use is a consistent correlate of intimate partner violence (IPV) in low-income and middle-income countries (LMICs). However, the magnitude of this association differs across studies, which may be due to contextual and methodological factors. This study aims to estimate and explore sources of heterogeneity in the association between alcohol use and IPV in 28 LMICs (n=109 700 couples). METHODS: In nationally representative surveys, partnered women reported on IPV victimisation and male partner's alcohol use. We estimated the relationship between alcohol use and IPV using logistic regression and full propensity score matching to account for confounding. Country-specific ORs were combined using a random-effects model. Country-level indicators of health and development were regressed on ORs to examine sources of variability in these estimates. RESULTS: Partner alcohol use was associated with a 2.55-fold increase in the odds of past-year IPV victimisation (95% CI 2.27 to 2.86) with substantial variability between regions (I2=70.0%). Countries with a low (<50%) prevalence of past-year alcohol use among men displayed larger associations between alcohol use and IPV. Exploratory analyses revealed that colonisation history, religion, female literacy levels and substance use treatment availability may explain some of the remaining heterogeneity observed in the strength of the association between alcohol use and IPV across countries. CONCLUSION: Partner alcohol use is associated with increased odds of IPV victimisation in LMICs, but to varying degrees across countries. Prevalences of male alcohol use and cultural factors were related to heterogeneity in these estimates between countries.
RESUMEN
This study longitudinally examined age differences across multiple outcome domains in individuals diagnosed with acute mild traumatic brain injury (mTBI). A sample of 447 adults meeting VA/DoD criteria for mTBI was dichotomized by age into older (≥65 years; n = 88) and younger (<65 years; n = 359) sub-groups. All participants presented to the emergency department within 24 hours of sustaining a head injury, and outcomes were assessed at 1-, 3-, and 6-month intervals. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9), post-concussive symptoms (PCS) were ascertained with the Rivermead Post-Concussion Questionnaire (RPQ), and functional recovery from the Extended Glasgow Outcome Scale (GOSE). Mixed effects logistic regression models showed that the rate of change over time in odds of functional improvement and symptom alleviation did not significantly differ between age groups (p = 0.200-0.088). Contrary to expectation, older adults showed equivalent outcome trajectories to younger persons across time. This is a compelling finding when viewed in light of the majority opinion that older adults are at risk for significantly worse outcomes. Future work is needed to identify the protective factors inherent to sub-groups of older individuals such as this.
