To carry out an economic evaluation of a task-shifting intervention for the treatment of depressive and anxiety disorders in primary-care settings in Goa, India.
Cost-utility and cost-effectiveness analyses based on generalized linear models were performed within a trial set in 24 public and private primary-care facilities. Subjects were randomly assigned to an intervention or a control arm. Eligible subjects in the intervention arm were given psycho-education, case management, interpersonal psychotherapy and/or antidepressants by lay health workers. Subjects in the control arm were treated by physicians. The use of health-care resources, the disability of each subject and degree of psychiatric morbidity, as measured by the Revised Clinical Interview Schedule, were determined at 2, 6 and 12 months.
Complete data, from all three follow-ups, were collected from 1243 (75.4%) and 938 (81.7%) of the subjects enrolled in the study facilities from the public and private sectors, respectively. Within the public facilities, subjects in the intervention arm showed greater improvement in all the health outcomes investigated than those in the control arm. Time costs were also significantly lower in the intervention arm than in the control arm, whereas health system costs in the two arms were similar. Within the private facilities, however, the effectiveness and costs recorded in the two arms were similar.
Within public primary-care facilities in Goa, the use of lay health workers in the care of subjects with common mental disorders was not only cost-effective but also cost-saving.

Intravenous administration
2022
Depression is disabling and highly prevalent. Intravenous (IV) ketamine displays rapid-onset antidepressant properties, but little is known regarding which patients are most likely to benefit, limiting personalized prescriptions. We identified randomized controlled trials of IV ketamine that recruited individuals with a relevant psychiatric diagnosis (e.g., unipolar or bipolar depression; post-traumatic stress disorder), included one or more control arms, did not provide any other study-administered treatment in conjunction with ketamine (although clinically prescribed concurrent treatments were allowable), and assessed outcome using either the Montgomery-Åsberg Depression Rating Scale or the Hamilton Rating Scale for Depression (HRSD-17). Individual patient-level data for at least one outcome was obtained from 17 of 25 eligible trials [pooled n = 809]. Rates of participant-level data availability across 33 moderators that were solicited from these 17 studies ranged from 10.8% to 100% (median = 55.6%). After data harmonization, moderators available in at least 40% of the dataset were tested sequentially, as well as with a data-driven, combined moderator approach. Robust main effects of ketamine on acute [~24-hours; β*(95% CI) = 0.58 (0.44, 0.72); p < 0.0001] and post-acute [~7 days; β*(95% CI) = 0.38 (0.23, 0.54); p < 0.0001] depression severity were observed. Two study-level moderators emerged as significant: ketamine effects (relative to placebo) were larger in studies that required a higher degree of previous treatment resistance to federal regulatory agency-approved antidepressant medications (≥2 failed trials) for study entry; and in studies that used a crossover design. A comprehensive data-driven search for combined moderators identified statistically significant, but modest and clinically uninformative, effects (effect size r ≤ 0.29, a small-medium effect). Ketamine robustly reduces depressive symptoms in a heterogeneous range of patients, with benefit relative to placebo even greater in patients more resistant to prior medications. In this largest effort to date to apply precision medicine approaches to ketamine treatment, no clinical or demographic patient-level features were detected that could be used to guide ketamine treatment decisions.Review Registration: PROSPERO Identifier: CRD42021235630

Tracking subjects’ strategies in behavioural choice experiments at trial resolution
2024
Investigating how, when, and what subjects learn during decision-making tasks requires tracking their choice strategies on a trial-by-trial basis. Here, we present a simple but effective probabilistic approach to tracking choice strategies at trial resolution using Bayesian evidence accumulation. We show this approach identifies both successful learning and the exploratory strategies used in decision tasks performed by humans, non-human primates, rats, and synthetic agents. Both when subjects learn and when rules change the exploratory strategies of win-stay and lose-shift, often considered complementary, are consistently used independently. Indeed, we find the use of lose-shift is strong evidence that subjects have latently learnt the salient features of a new rewarded rule. Our approach can be extended to any discrete choice strategy, and its low computational cost is ideally suited for real-time analysis and closed-loop control.

Safer conception counseling supports HIV-serodifferent couples to meet reproductive goals while minimizing HIV transmission risk, but has not been integrated into routine HIV care. We piloted a novel safer conception program in an established public-sector HIV clinic in Uganda to inform future implementation. In-depth interviews and counseling observations explored experiences of program clients and healthcare providers to assess program acceptability, appropriateness, and feasibility. Fifteen index clients (8 women, 7 men), 10 pregnancy partners, and 10 providers completed interviews; 15 participants were living with HIV. Ten observations were conducted. We identified four emergent themes: (1) High demand for safer conception services integrated within routine HIV care, (2) Evolving messages of antiretroviral treatment as prevention contribute to confusion about HIV prevention options, (3) Gender and sexual relationship power inequities shape safer conception care, and (4) HIV-related stigma impacts safer conception care uptake. These findings confirm the need for safer conception care and suggest important implementation considerations.

Mental, neurological, and substance use (MNS) disorders are leading causes of the global burden of disease and profoundly impact the social and economic well-being of individuals and communities. The majority of people affected by MNS disorders globally do not have access to evidence-based interventions and many experience discrimination and abuses of their human rights. A United Nations General Assembly Special Session (UNGASS) is needed to focus global attention on MNS disorders as a core development issue requiring commitments to improve access to care, promote human rights, and strengthen the evidence on effective prevention and treatment.

Amongst HIV+ individuals, sleep complaints have been recognized as common and debilitating; but have rarely been formally assessed or compared to controls using validated sleep tools. In this study we conducted structured interview for sleep disorders, polysomnography, 2-week home (ambulatory) monitoring and validated sleep/functional questionnaires. 56 % (14/25) of HIV+ participants and 0 % (0/19) of controls fulfilled the diagnostic criteria for insomnia. Insomnia severity scores were correlated with fatigue and anxiety symptoms. Sleep latency on 2-week actigraphy was significantly longer (
P
= 0.027) for HIV+ participants and associated with lower MOS-HIV scores. Sleep quality was significantly reduced in HIV+ participants based on validated questionnaires of overall sleep quality (
P
= 0.0017) and insomnia related symptoms (
P
< 0.001) even after adjusting for education and affective symptoms. HIV+ individuals are suffering with under-diagnosed sleep disorders that are negatively impacting quality of life and functional capabilities. Further studies aimed at improving recognition of sleep disorders and implementation of efficacious medical and behavioral treatment could improve functioning and disease management.

Early maternal depressive symptoms and child growth trajectories: a longitudinal analysis of a nationally representative US birth cohort
2014
Background
Maternal depressive symptoms are negatively associated with early child growth in developing countries; however, few studies have examined this relation in developed countries or used a longitudinal design with data past the second year of the child’s life. We investigated if and when early maternal depressive symptoms affect average growth in young children up to age 6 in a nationally representative sample of US children.
Methods
Using data from 6,550 singleton births from the Early Childhood Longitudinal Study -- Birth Cohort (ECLS-B), we fit growth trajectory models with random effects to examine the relation between maternal depressive symptoms at 9 months based on the twelve-item version of the Center for Epidemiologic Studies Depression Scale (CES-D) and child height and body mass index (BMI) to age 6 years.
Results
Mothers with moderate/severe depressive symptoms at 9 months postpartum had children with shorter stature at this same point in time [average 0.26 cm shorter; 95% CI: 5 cm, 48 cm] than mothers without depressive symptoms; children whose mothers reported postpartum depressive symptoms remained significantly shorter throughout the child’s first 6 years.
Conclusions
Results suggest that the first year postpartum is a critical window for addressing maternal depressive symptoms in order to optimize child growth. Future studies should investigate the role of caregiving and feeding practices as potential mechanisms linking maternal depressive symptoms and child growth trajectories.

The fellowship aims to develop independent and productive clinical investigators, and emphasizes creation of collaborative partnerships and bidirectional (i.e., mutually beneficial) capacity building to improve population health in both directions. [...]lessons learned from global work have direct implications for the U.S., where there continue to be disparities in accessing quality care for traditionally underserved groups [8]. [...]of this community-identified need, the Health and Mental Health Education and Awareness for Africans in Lowell (HEAAL) was co-founded with Christ Jubilee International Ministries in 2014 with the goal of informing the development of mental health resources tailored to the community’s needs [15]. [...]our local community better recognized their needs for mental health care and were open to further engagement with mental health providers, and our global work was strengthened after including our local partners’ knowledge into our data collection and interpretation. Additionally, outside of the direct impacts to the global and local Liberian population, this type of bidirectional learning offers opportunities for training psychiatrists, clinical psychologists, and allied mental health professionals (professions in the fields of Behavioral Analysis, Educational Psychology, Marriage and Family Therapy, Mental

Social and fieldworkers face enormous challenges in assisting millions of Syrian refugees in Lebanon since the Syrian war in 2011. We sought to assess the feasibility and acceptability of an adapted version of the SMART-3RP (Stress Management Relaxation Response Resilience Training) training to address the emotional and physical burden on the humanitarian field. Data were collected using the Symptom Checklist-90 (SCL-90), blood pressure, pulse and a brief qualitative survey at months 0, 3, 6 and 9. We compared mean SCL-90 scores and physiological measures from these time points and subjected qualitative data to a thematic analysis. Mean values of all measures decreased from months 0 to 9, with significance in SCL-90 changes increasing at each visit. Qualitative themes included decreased stress, increased positivity and problem-solving skills, interpersonal and personal benefits of mindfulness practice and the need to continue and expand the programme. Qualitative and quantitative analyses showed a decrease in stress perception and blood pressure, demonstrating the physiological benefits of mind body approaches. We highlight the importance of self-care for humanitarian workers as the basis for the mission's success. We invite additional research to confirm these findings and their implications for the humanitarian field.
