RESUMEN
INTRODUCTION: We assessed the impact of a personal agency-based training for refugee women and their male partners on their economic and social empowerment, rates of intimate partner violence (IPV), and non-partner violence (NPV). METHODS: We conducted an individually randomized controlled trial with 1061 partnered women (aged 18-45) living in a refugee camp in Rwanda. Women received two days of training, and their partners received one day of training. The follow-up survey where all relevant outcomes were assessed was carried out at 6-9 months post-intervention. RESULTS: At follow up, women in the intervention arm were more likely to report partaking in income generating activities (aIRR 1.27 (1.04-1.54), p < 0.05) and skill learning (aIRR 1.59 (1.39-1.82), p < 0.001) and reported a reduction in experience of physical or sexual NPV in the past six months (aIRR 0.65 (0.39-1.07), p < 0.09). While improved, no statistically significant impacts were seen on physical or sexual IPV (aIRR 0.80 (0.58-1.09), p = 0.16), food insecurity (ß 0.98 (0.93 to 1.03), p = 0.396), or clean cookstove uptake (aIRR 0.95 (0.88 to 1.01), p = 0.113) in the past six months. We found statistically significant reduction in physical and sexual IPV amongst those experiencing IPV at baseline (aIRR 0.72 (0.50 to 1.02), p < 0.07). Small improvements in self-efficacy scores and our indicator of adapting to stress were seen in the intervention arm. Some challenges were also seen, such as higher prevalence of probable depression and/or anxiety (aIRR 1.79 (1.00-3.22), p = 0.05) and PTSD (aIRR 2.07 (1.10-3.91), p < 0.05) in the intervention arm compared to the control arm. CONCLUSION: Our findings echo previous research showing personal agency training can support economic well-being of women. We also find potentially promising impacts on gender-based violence. However, there is some evidence that integration of evidence-based mental health support is important when enhancing agency amongst conflict-affected populations. TRIAL REGISTRATION NUMBER: The trial was registered with ClinicalTrials.gov, Identifier: NCT04081441 on 09/09/2019.

Decreased neuronal specificity of the brain in response to cognitive demands (i.e., neural dedifferentiation) has been implicated in age-related cognitive decline. Investigations into functional connectivity analogs of these processes have focused primarily on measuring segregation of nonoverlapping networks at rest. Here, we used an edge-centric network approach to derive entropy, a measure of specialization, from spatially overlapping communities during cognitive task fMRI. Using Human Connectome Project Lifespan data (713 participants, 36-100â years old, 55.7% female), we characterized a pattern of nodal despecialization differentially affecting the medial temporal lobe and limbic, visual, and subcortical systems. At the whole-brain level, global entropy moderated declines in fluid cognition across the lifespan and uniquely covaried with age when controlling for the network segregation metric modularity. Importantly, relationships between both metrics (entropy and modularity) and fluid cognition were age dependent, although entropy's relationship with cognition was specific to older adults. These results suggest entropy is a potentially important metric for examining how neurological processes in aging affect functional specialization at the nodal, network, and whole-brain level.

Introduction: People with multiple sclerosis (PwMS) experience a range of physical, cognitive, and affective symptoms. Behavioral interventions targeting increased physical activity show promising support as low-cost methods to improve working memory, episodic memory, and processing speed in PwMS. In this randomized controlled trial, we will examine the efficacy of a pedometer-tracking intervention, designed to increase low-to-moderate levels of physical activity, for improving working memory in PwMS. Methods and Analysis: Eighty-seven PwMS, between the ages of 30-59, have been recruited for the study. Seventy-five of the eligible and interested individuals were randomized to six-month health behavior monitoring groups: a Step-track group or a Water-track group (serving as the active control). Neuropsychological measures, assessing the primary outcome of the study, were administered at pre, midpoint, and post-intervention. Exploratory factor analysis of neuropsychological measures resulted in three factors: a working memory/processing speed factor, a visual episodic memory factor, and a verbal episodic memory factor. Changes in this latent measure of working memory/processing speed is the primary outcome of the current study. Functional MRI data will be analyzed to examine changes in the functional connectivity of the neural network supporting working memory. Ethics and dissemination: The institutional review board granted approval for the study and all participants provided written informed consent. The results of this study will provide support showing that step-tracking increases overall levels of physical activity, improves working memory and processing speed, and strengthens the neural circuitry that supports better cognition. Evidence from this study will thus offer promising support for the routine use of step-tracking devices to improve cognitive functioning in PwMS. Study results will be disseminated through peer-reviewed publications and presentations at scientific conferences.
RESUMEN
BACKGROUND: Mindfulness meditation is a form of mind-body intervention that has increasing scientific support for its ability to reduce age-related declines in cognitive functioning, improve affective health, and strengthen the neural circuitry supporting improved cognitive and affective health. However, the majority of existent studies have been pilot investigations with small sample sizes, limited follow-up data, and a lack of attention to expectancy effects. Here, we present the study design of a Phase I/II, efficacy trial-HealthyAgers trial-that examines the benefits of a manualized mindfulness-based stress reduction program in improving attentional control and reducing mind-wandering in older adults. METHODS: One hundred fifty older adults (ages 65-85 years) will be randomized into one of two groups: an eight-week mindfulness program or an eight-week, placebo-controlled, lifestyle education program. Behavioral and neuroimaging assessments are conducted before and after the training. Participants are then invited to booster sessions once every three months for a period of 12 months with post-intervention follow-up assessments conducted at 6-months and 12-months. The primary outcomes for the study are behavioral measures of attentional control and mind-wandering. Additional, secondary outcomes include network strength in an a priori defined neuromarker of attentional control, fluid and everyday cognition, emotion regulation strategy use, and markers of inflammation. DISCUSSION: This study will establish the efficacy of a group-based, low-cost mind-body intervention for the inter-related facets of attentional control and mind-wandering in older adults. Strengths of this study include a well-designed, placebo-controlled comparison group, use of web/mobile application to track study adherence, and longitudinal follow-up.

Introduction: Individuals with multiple sclerosis (MS) are vulnerable to deficits in working memory (WM), but the search for neural correlates of WM within circumscribed areas has been inconclusive. Given the widespread neural alterations observed in MS, predictive modeling approaches that capitalize on whole-brain connectivity may better capture individual differences in WM. Materials and Methods: We applied connectome-based predictive modeling to functional magnetic resonance imaging data from WM tasks in two independent samples with relapsing-remitting MS. In the internal sample (ninternal = 36), cross-validation was used to train a model to predict accuracy on the Paced Visual Serial Addition Test from functional connectivity. We hypothesized that this MS-specific model would successfully predict performance on the N-back task in the validation cohort (nvalidation = 36). In addition, we assessed the generalizability of existing WM networks derived in healthy young adults to these samples, and we explored anatomical differences between the healthy and MS networks. Results: We successfully derived an MS-specific predictive model of WM in the internal sample (full: rs = 0.47, permuted p = 0.011), but the predictions were not significant in the validation cohort (rs = -0.047; p = 0.78, mean squared error [MSE] = 0.006, R2 = -2.21%). In contrast, the healthy networks successfully predicted WM in both MS samples (internal: rs = 0.33 p = 0.049, MSE = 0.009, R2 = 13.4%; validation cohort: rs = 0.46, p = 0.005, MSE = 0.005, R2 = 16.9%), demonstrating their translational potential. Discussion: Functional networks identified in a large sample of healthy individuals predicted significant variance in WM in MS. Networks derived in small samples of people with MS may have limited generalizability, potentially due to disease-related heterogeneity. The robustness of models derived in large clinical samples warrants further investigation. ClinicalTrials.gov ID: NCT03244696.

We describe the spatiotemporal course of cortical high-gamma activity, hippocampal ripple activity and interictal epileptiform discharges during an associative memory task in 15 epilepsy patients undergoing invasive EEG. Successful encoding trials manifested significantly greater high-gamma activity in hippocampus and frontal regions. Successful cued recall trials manifested sustained high-gamma activity in hippocampus compared to failed responses. Hippocampal ripple rates were greater during successful encoding and retrieval trials. Interictal epileptiform discharges during encoding were associated with 15% decreased odds of remembering in hippocampus (95% confidence interval 6-23%). Hippocampal interictal epileptiform discharges during retrieval predicted 25% decreased odds of remembering (15-33%). Odds of remembering were reduced by 25-52% if interictal epileptiform discharges occurred during the 500-2000 ms window of encoding or by 41% during retrieval. During encoding and retrieval, hippocampal interictal epileptiform discharges were followed by a transient decrease in ripple rate. We hypothesize that interictal epileptiform discharges impair associative memory in a regionally and temporally specific manner by decreasing physiological hippocampal ripples necessary for effective encoding and recall. Because dynamic memory impairment arises from pathological interictal epileptiform discharge events competing with physiological ripples, interictal epileptiform discharges represent a promising therapeutic target for memory remediation in patients with epilepsy.

INTRODUCTION: India's national AIDS Control Organization implemented World Health Organization's option B+ HIV prevention of mother-to-child transmission (PMTCT) guidelines in 2013. However, scalable strategies to improve uptake of new PMTCT guidelines to reduce new infection rates are needed. This study assessed impact of Mobile Health-Facilitated Behavioral Intervention on the uptake of PMTCT services. METHODS: A cluster-randomized trial of a mobile health (mHealth)-supported behavioural training intervention targeting outreach workers (ORWs) was conducted in four districts of Maharashtra, India. Clusters (one Integrated Counselling and Testing Center (ICTC, n = 119), all affiliated ORWs (n = 116) and their assigned HIV-positive pregnant/postpartum clients (n = 1191)) were randomized to standard-of-care (SOC) ORW training vs. the COMmunity home Based INDia (COMBIND) intervention - specialized behavioural training plus a tablet-based mHealth application to support ORW-patient communication and patient engagement in HIV care. Impact on uptake of maternal antiretroviral therapy at delivery, exclusive breastfeeding at six months, infant nevirapine prophylaxis, and early infant diagnosis at six months was assessed using multi-level random-effects logistic regression models. RESULTS: Of 1191 HIV-positive pregnant/postpartum women, 884 were eligible for primary outcome assessment; 487 were randomized to COMBIND. Multivariable analyses identified no statistically significant differences in any primary outcome by study arm. COMBIND was associated with higher uptake of exclusive breastfeeding at two months (adjusted Odds Ratio (aOR), 2.10; 95% CI 1.06 to 4.15) and early infant diagnosis at six weeks (aOR, 2.19; 95% CI 1.05 to 3.98) than SOC. CONCLUSIONS: The COMBIND intervention was easily integrated into India's existing PMTCT programme and improved early uptake of two PMTCT components that require self-motivated health-seeking behaviour, thus providing preliminary evidence to support COMBIND as a potentially scalable PMTCT strategy. Further study would identify modifications needed to optimize other PMTCT outcomes.

Stove stacking (concurrent use of multiple stoves and/or fuels) is a poorly quantified practice in regions where efforts to transition household energy to cleaner stoves/or fuels are on-going. Using biomass-burning stoves alongside clean stoves undermines health and environmental goals. This review synthesizes stove stacking data gathered from eleven case studies of clean cooking programs in low/middle-income country settings. Analyzed data are from ministry and program records, research studies, and informant interviews. Thematic analysis identify key drivers of stove stacking behavior in each setting. Significant (28%-100%) stacking with traditional cooking methods was observed in all cases. Reason for traditional fuel use includes: costs of clean fuel; mismatches between cooking technologies and household needs; and unreliable fuel supply. National household surveys often focus on 'primary' cookstoves and miss stove stacking data. Thus more attention should be paid to discontinuation of traditional stove use, not solely adoption of cleaner stoves/fuels. Future energy policies and programs should acknowledge the realities of stacking and incorporate strategies at the design stage to transition away from polluting stoves/fuels. Seven principles for clean cooking system program design and policy are presented, focused on a shift toward "cleaner stacking" that could yield household air pollution reductions approaching WHO targets.
RESUMEN
BACKGROUND: A cluster-randomized trial recently demonstrated that an integrated behavioral and mobile technology intervention improved uptake of key components of a Prevention of Mother to Child Transmission (PMTCT) Option B+ program, among HIV- infected pregnant/breastfeeding women in India. To guide scale-up and optimize programmatic implementation, we conducted a mixed-methods evaluation of the feasibility and acceptability of this intervention. METHODS: The COMmunity Home Based INDia (COMBIND) study, was conducted in four districts of Maharashtra, India and randomized 119 integrated counseling and testing centers (ICTC) and their outreach workers (ORWs) to the COMBIND intervention, an integrated mHealth application that allowed digital data capture, PMTCT educational videos, SMS alerts for missed visits and reminder for visits, combined with personal empowerment and motivational interviewing training for ORWs. This qualitative evaluation was done through 15 in-depth interviews (IDIs) with ORWs and 15 IDIs with HIV-infected pregnant/breastfeeding women from the intervention arm. Utilizing a concurrent nested mixed-method evaluation approach, we assess the feasibility and acceptability of the study intervention. RESULTS: All 30 participants reported that the PMTCT videos were essential in providing easy to understand information on critical aspects of HIV and necessary care related to PMTCT practices. A majority of the ORWs reported that the personal empowerment training with motivational interviewing skills training increased their confidence, motivation and gave them the tools for effectively supporting their clients. The mHealth application improved their working style as it facilitated targeted PMTCT information support, systemized data capture, streamlined their health education delivery practice and provided a sense of work satisfaction. The SMS appointment alerts improved retention in HIV care for mother and baby to the smaller proportion that had access to their phones. Despite reported improvements in knowledge and communication, few ORWs reported that structural challenges such as limited drug stocks, lack of HIV kits or unavailability of trained staff at ICTC, may hamper the uptake of PMTCT services, thus resulting in limited significant impacts of COMBIND on PMTCT outcomes. CONCLUSION: This study found that COMBIND intervention is scalable, feasible, beneficial and very well accepted by ORWs and patients, however structural challenges in goods and services remain.

Slow oscillations and spindle activity during non-rapid eye movement sleep have been implicated in memory consolidation. Closed-loop acoustic stimulation has previously been shown to enhance slow oscillations and spindle activity during sleep and improve verbal associative memory. We assessed the effect of closed-loop acoustic stimulation during a daytime nap on a virtual reality spatial navigation task in 12 healthy human subjects in a randomized within-subject crossover design. We show robust enhancement of slow oscillation and spindle activity during sleep. However, no effects on behavioral performance were observed when comparing real versus sham stimulation. To explore whether memory enhancement effects were task specific and dependent on nocturnal sleep, in a second experiment with 19 healthy subjects, we aimed to replicate a previous study that used closed-loop acoustic stimulation to enhance memory for word pairs. The methods used were as close as possible to those used in the original study, except that we used a double-blind protocol, in which both subject and experimenter were unaware of the test condition. Again, we successfully enhanced slow oscillation and spindle power, but again did not strengthen associative memory performance with stimulation. We conclude that enhancement of sleep oscillations may be insufficient to enhance memory performance in spatial navigation or verbal association tasks, and provide possible explanations for lack of behavioral replication.

Direct recordings from the human brain have historically involved epilepsy patients undergoing invasive electroencephalography (iEEG) for surgery. However, these measurements are temporally limited and affected by clinical variables. The RNS System (NeuroPace, Inc.) is a chronic, closed-loop electrographic seizure detection and stimulation system. When adapted by investigators for research, it facilitates cognitive testing in a controlled ambulatory setting, with measurements collected over months to years. We utilized an associative learning paradigm in 5 patients with traditional iEEG and 3 patients with chronic iEEG, and found increased hippocampal gamma (60-100 Hz) sustained at 1.3-1.5 seconds during encoding in successful versus failed trials in surgical patients, with similar results in our RNS System patients (1.4-1.6 seconds). Our findings replicate other studies demonstrating that sustained hippocampal gamma supports encoding. Importantly, we have validated the RNS System to make sensitive measurements of hippocampal dynamics during cognitive tasks in a chronic ambulatory research setting.

This paper outlines the critical role of personal agency in influencing health and development outcomes and presents a framework for implementing non-therapeutic cognitive-behavioral interventions that foster agency, especially for women, in resource-poor settings. The United Nations' Sustainable Development Goals (SDGs) has placed "empowerment" at the center of global targets, particularly to improve individuals' health and development. Despite extensive research on individual and community empowerment, there is limited focus on the role of psychological and behavioral approaches directly fostering individual and collective agency in health programs. Fundamental to this process is the understanding that decision-making is an interaction between mental processes and one's current context. Approaches that allow individuals to understand how their beliefs, values, emotions, and thoughts impact their behaviors and can be modulated to increase their personal agency are needed. This model is illustrated through a pilot behavioral intervention with women engaged in sex work in Pune, India, demonstrating substantive benefits.

BACKGROUND: The Prevention of Mother-to-Child Transmission of HIV (PMTCT) program in India is one of the largest in the world. It uses outreach workers (ORWs) to facilitate patient uptake of services, however, the challenges faced by the ORWs, and their views about the effectiveness of this program are unknown. METHODS: The COMmunity-Home Based INDia (COMBIND) Prevention of Mother to Child Transmission of HIV study evaluated an integrated mobile health and behavioral intervention to enhance the capacity of ORWs in India. To understand the challenges faced by ORWs, and their perceptions of opportunities for program improvement, four group discussions were conducted among 60 ORW from four districts of Maharashtra, India, as part of the baseline assessment for COMBIND. Data were qualitatively analyzed using a thematic approach. RESULTS: Numerous personal-, social-, and structural-level challenges existed for ORW as they engaged with their patients. Personal-level challenges for ORWs included disclosure of their own HIV status and travelling costs for home visits. Personal-level challenges for patients included financial costs of travelling to ART centers, non-adherence to ART, loss of daily wages, non-affordability of infant formula, lack of awareness of the baby's needs, financial dependence on family, four time points (6weeks, 6 months, 12 months and 18 months) for HIV tests, and need for nevirapine (NVP) prophylaxis. Social-level challenges included lack of motivation by patients and/or health care staff, social stigma, and rude behavior of health care staff and their unwillingness to provide maternity services to women in the PMTCT programme. Structural-level challenges included cultural norms around infant feeding, shortages of HIV testing kits, shortages of antiretroviral drugs and infant NVP prophylaxis, and lack of training/knowledge related to PMTCT infant feeding guidelines by hospital staff. The consensus among ORWs was that there was a critical need for tools and training to improve their capacity to effectively engage with patients, and deliver appropriate care, and for motivation through periodic feedback. CONCLUSIONS: Given the significant challenges in PMTCT programme implementation reported by ORW, novel strategies to address these challenges are urgently needed to improve patient engagement, and access to and retention in care.

BACKGROUND: Gender-based violence (GBV) is a major global public health concern and is a risk factor for adverse health outcomes. Early identification of GBV is crucial for improved health outcomes. Interactions with health care providers may provide a unique opportunity for routine GBV screening, if a safe, confidential environment can be established. METHODS: Between November 2014 and February 2015, a cross-sectional, observational study was conducted where women were interviewed about their opinions concerning GBV screening in a tertiary health care setting in Pune, India. Trained counsellors interviewed 300 women at different out-patient and in-patient departments using a semi-structured questionnaire. RESULTS: Twenty-three percent of these women reported experiencing GBV in their life. However, 90% of women said they had never been asked about GBV in a health care setting. Seventy-two percent expressed willingness to be asked about GBV by their health care providers, with the preferred provider being nurses or counsellors. More than half (53%) women reported face-to-face interview as the most preferred method for screening. There were no major differences in these preferences by GBV history status. CONCLUSIONS: Our study provides evidence for preferred GBV screening methods and optimal provider engagement as perceived by women attending a public hospital.

Approximately 3 billion people, most of whom live in Asia, Africa, and the Americas, rely on solid fuels (i.e. wood, crop wastes, dung, charcoal) and kerosene for their cooking needs. Exposure to household air pollution from burning these fuels is estimated to account for approximately 3 million premature deaths a year. Cleaner fuels - such as liquefied petroleum gas, biogas, electricity, and certain compressed biomass fuels - have the potential to alleviate much of this significant health burden. A wide variety of clean cooking intervention programs are being implemented around the world, but very few of these efforts have been analyzed to enable global learning. The Clean Cooking Implementation Science Network (ISN), supported by the U.S. National Institutes of Health (NIH) and partners, identified the need to augment the publicly available literature concerning what has worked well and in what context. The ISN has supported the development of a systematic set of case studies, contained in this Special Issue, examining clean cooking program rollouts in a variety of low- and middle-income settings around the world. We used the RE-AIM (reach, effectiveness, adaptation, implementation, maintenance) framework to coordinate and evaluate the case studies. This paper describes the clean cooking case studies project, introduces the individual studies contained herein, and proposes a general conceptual model to support future planning and evaluation of household energy programs.

Globally, women's involvement in clean cooking value chains has been minimal. This is partly because of the multiple challenges faced by women that impede their capacity to effectively engage in the energy sector. To better discern gender-specific differences in involvement in the energy sector, the authors conducted a randomized trial in Kenya to compare sales performance of newly trained male and female improved cookstove entrepreneurs and to test the effects of an agency-based empowerment training on business activity. A total of 257 entrepreneurs completed either a 4-day entrepreneurial training (control) or a 4-day empowerment training (intervention) and were followed for nearly 8 months documenting business activity and sales. The empowerment training led to more than doubling of sales for both genders. In addition, participants in the intervention group were significantly more likely to demonstrate business commitment over time and nearly three times more likely to be higher sellers (relative risk = 2.7, 95% CI [1.4, 5.4]), controlling for gender and rural/urban locale. Women outsold men by a margin of nearly 3 to 1 and were more likely to continue to pursue leads despite limited sales. Nonactive participants (those selling 1 improved cookstove or less) were a larger percentage of the control group (72%) than the intervention group (50%), and more men were nonactive participants (65% of men) compared with women (56% of women).These data show that women can serve as active improved cookstove entrepreneurs in both urban and rural settings and that targeted agency-based empowerment training can significantly increase women's capacity to engage effectively within the improved cookstove value chain.

To examine the relationship between measures of mother's caretaking, practice and individual agency on acute diarrhea and respiratory tract infections (ARTIs) of Indonesian children. Using population-based household data from the Indonesian Demographic Health Surveys for 2002-2003 (n = 9,151 children) and 2007 (n = 9,714 children), we selected 28 indicators related to mother' caretaking, and applied principal component analysis to derive indices for access to care, practice and experience, and agency. The association between index quartiles (level 1-4) and the prevalence of diarrhea and ARTIs in the youngest child <5 years of age was assessed with multivariate logistic regression adjusting for socioeconomic status, residence type, mother's age and education, family size, child's age and sex, immunization status and received vitamin A supplementation. Moderate levels (level 3) of practice and experience were associated with decreased diarrheal risk (adjusted OR 0.86, 95 % CI 0.75-0.98), but not for ARTIs. Children of mothers with higher levels (level 4) of agency were protected against both diarrhea (adjusted OR 0.68, 95 % CI 0.60-0.77) and ARTIs (adjusted OR 0.77, 95 % CI 0.66-0.91). Stratified analyses with child's age and mother's education, and tests of interaction, showed that agency had a stronger effect on diarrhea and ARTIs prevalence in children <2 years of age. Maternal caretaking, especially agency, is strongly associated with lower prevalence of diarrhea and ARTIs in younger children. Interventions specifically designed to promote maternal autonomy and decision-making may lead to improved child health.

Background. Tuberculosis (TB) remains a significant global public health problem with known gender-related (male versus female) disparities. We reviewed the qualitative evidence (written/spoken narrative) for gender-related differences limiting TB service access from symptom onset to treatment initiation. Methods. Following a systematic process, we searched 12 electronic databases, included qualitative studies that assessed gender differences in accessing TB diagnostic and treatment services, abstracted data, and assessed study validity. Using a modified "inductive coding" system, we synthesized emergent themes within defined barriers and delays limiting access at the individual and provider/system levels and examined gender-related differences. Results. Among 13,448 studies, 28 studies were included. All were conducted in developing countries and assessed individual-level barriers; 11 (39%) assessed provider/system-level barriers, 18 (64%) surveyed persons with suspected or diagnosed TB, and 7 (25%) exclusively surveyed randomly sampled community members or health care workers. Each barrier affected both genders but had gender-variable nature and impact reflecting sociodemographic themes. Women experienced financial and physical dependence, lower general literacy, and household stigma, whereas men faced work-related financial and physical barriers and community-based stigma. Conclusions. In developing countries, barriers limiting access to TB care have context-specific gender-related differences that can inform integrated interventions to optimize TB services.
