Eff ect of participatory women’s groups facilitated by Accredited Social Health Activists on birth outcomes in rural eastern India: a cluster-randomised controlled trial

Background A quarter of the world’s neonatal deaths and 15% of maternal deaths happen in India. Few community-based strategies to improve maternal and newborn health have been tested through the country’s government-approved Accredited Social Health Activists (ASHAs). We aimed to test the eff ect of participatory women’s groups facilitated by ASHAs on birth outcomes, including neonatal mortality. Methods In this cluster-randomised controlled trial of a community intervention to improve maternal and newborn health, we randomly assigned (1:1) geographical clusters in rural Jharkhand and Odisha, eastern India to intervention (participatory women’s groups) or control (no women’s groups). Study participants were women of reproductive age (15–49 years) who gave birth between Sept 1, 2009, and Dec 31, 2012. In the intervention group, ASHAs supported women’s groups through a participatory learning and action meeting cycle. Groups discussed and prioritised maternal and newborn health problems, identifi ed strategies to address them, implemented the strategies, and assessed their progress. We identifi ed births, stillbirths, and neonatal deaths, and interviewed mothers 6 weeks after delivery. The primary outcome was neonatal mortality over a 2 year follow up. Analyses were by intention to treat. This trial is registered with ISRCTN, number ISRCTN31567106. Findings Between September, 2009, and December, 2012, we randomly assigned 30 clusters (estimated population 156 519) to intervention (15 clusters, estimated population n=82 702) or control (15 clusters, n=73 817). During the follow-up period (Jan 1, 2011, to Dec 31, 2012), we identifi ed 3700 births in the intervention group and 3519 in the control group. One intervention cluster was lost to follow up. The neonatal mortality rate during this period was 30 per 1000 livebirths in the intervention group and 44 per 1000 livebirths in the control group (odds ratio [OR] 0.69, 95% CI 0·53–0·89). Interpretation ASHAs can successfully reduce neonatal mortality through participatory meetings with women’s groups. This is a scalable community-based approach to improving neonatal survival in rural, underserved areas of India

Community mobilisation with women's groups facilitated by Accredited Social Health Activists (ASHAs) to improve maternal and newborn health in underserved areas of Jharkhand and Orissa: study protocol for a cluster-randomised controlled trial

Background: Around a quarter of the world's neonatal and maternal deaths occur in India. Morbidity and mortality are highest in rural areas and among the poorest wealth quintiles. Few interventions to improve maternal and newborn health outcomes with government-mandated community health workers have been rigorously evaluated at scale in this setting.The study aims to assess the impact of a community mobilisation intervention with women's groups facilitated by ASHAs to improve maternal and newborn health outcomes among rural tribal communities of Jharkhand and Orissa.Methods/design: The study is a cluster-randomised controlled trial and will be implemented in five districts, three in Jharkhand and two in Orissa. The unit of randomisation is a rural cluster of approximately 5000 population. We identified villages within rural, tribal areas of five districts, approached them for participation in the study and enrolled them into 30 clusters, with approximately 10 ASHAs per cluster. Within each district, 6 clusters were randomly allocated to receive the community intervention or to the control group, resulting in 15 intervention and 15 control clusters. Randomisation was carried out in the presence of local stakeholders who selected the cluster numbers and allocated them to intervention or control using a pre-generated random number sequence. The intervention is a participatory learning and action cycle where ASHAs support community women's groups through a four-phase process in which they identify and prioritise local maternal and newborn health problems, implement strategies to address these and evaluate the result. The cycle is designed to fit with the ASHAs' mandate to mobilise communities for health and to complement their other tasks, including increasing institutional delivery rates and providing home visits to mothers and newborns. The trial's primary endpoint is neonatal mortality during 24 months of intervention. Additional endpoints include home care practices and health care-seeking in the antenatal, delivery and postnatal period. The impact of the intervention will be measured through a prospective surveillance system implemented by the project team, through which mothers will be interviewed around six weeks after delivery. Cost data and qualitative data are collected for cost-effectiveness and process evaluations

Deep phenotyping and genomic data from a nationally representative study on dementia in India

The Harmonized Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India (LASI-DAD) is a nationally representative in-depth study of cognitive aging and dementia. We present a publicly available dataset of harmonized cognitive measures of 4,096 adults 60 years of age and older in India, collected across 18 states and union territories. Blood samples were obtained to carry out whole blood and serum-based assays. Results are included in a venous blood specimen datafile that can be linked to the Harmonized LASI-DAD dataset. A global screening array of 960 LASI-DAD respondents is also publicly available for download, in addition to neuroimaging data on 137 LASI-DAD participants. Altogether, these datasets provide comprehensive information on older adults in India that allow researchers to further understand risk factors associated with cognitive impairment and dementia.Peer reviewe

Assessment and comparison of the memory profile in traumatic brain injury and subarachnoid hemorrhage patients

Background: Traumatic brain injury (TBI) and Subarachnoid Hemorrhage (SAH) are the leading cause of death and disability in both developed and developing countries. They have significant cognitive and behavioral consequences, affecting the quality of life of both patients and their families. Aim: To compare the memory functioning of TBI and SAH and study the effect of demographics on the same through a retrospective study. Materials and Methods: A sample of 210 patients clinically diagnosed as TBI (N = 165; M = 145/F = 20) and SAH (N = 45; M = 35/F = 10) were using post graduate institute of memory scale (PGI-MS) which assesses 10 memory domains. Results: Odds Ratio (OR) was calculated by categorizing the scores as average and impaired on PGI-MS, the percentage of impaired cases of SAH were significantly less as compared to TBI (8.9% vs. 22.4%; OR = 0.34) Moreover, only two domains were found to have significant results, i.e. delayed recall and recognition. When the scores were adjusted for age, education and gender, memory impairment was found to be statistically significant in domains of remote memory (OR = O.10) recent memory (OR = 0.32), delayed recall (OR = 0.26), immediate memory (OR = 0.30), new learning ability (OR = 0.38), and recognition (OR = 0.17). Conclusion: A primary prevention (awareness program about risk factors) and tertiary prevention (holistic rehabilitation) would play a crucial role in improving the quality of life of both patients as well as the population at risk

Enhancing memory and activities of daily living in patients with early Alzheimer's disease using memory stimulation intervention: A randomized controlled trial

Objective: The objective of this study was to assess the effectiveness of memory stimulation intervention added to donepezil treatment as compared to donepezil alone in patients with early Alzheimer's disease (eAD). Materials and Methods: Patients in the combined treatment group (CTG = 21) received standard dosages of donepezil and weekly memory stimulation activities sessions for 2 months, whereas the treatment as usual group (TAU = 22) received only standard dosages of donepezil. Each session had extensive tasks on memory and its implied practice on instrumental activities of daily living. After 8 sessions, both groups were evaluated for changes in memory and functional outcomes by administering the mini-mental state examination (MMSE), memory (Postgraduate Institute of Memory Scale), and instrumental activities of daily living scale (IADLS). This trial was registered on the Clinical Trials Registry - India (CTRI/2014/04/004550). Results: Statistical analysis was done using independent t-test, which revealed a significant difference between the groups on MMSE, memory, and IADLS post intervention. The MMSE score in the TAU group, while it increased in the CTG group by 4 points. A similar trend was evident in the memory and IADLS scores as well. Effect size in the CTG group was relatively large as compared to the TAU group where the effects were small and negative on some outcomes. Conclusion: The CTG group showed positive treatment effect on cognitive tests suggesting that combined memory stimulation and donepezil treatment has potential to improve the cognitive and functional performance of patients with eAD

Proteomic Investigation of <em>Falciparum</em> and <em>Vivax</em> Malaria for Identification of Surrogate Protein Markers

<div><p>This study was conducted to analyze alterations in the human serum proteome as a consequence of infection by malaria parasites <em>Plasmodium falciparum</em> and <em>P. vivax</em> to obtain mechanistic insights about disease pathogenesis, host immune response, and identification of potential protein markers. Serum samples from patients diagnosed with <em>falciparum</em> malaria (FM) (n = 20), <em>vivax</em> malaria (VM) (n = 17) and healthy controls (HC) (n = 20) were investigated using multiple proteomic techniques and results were validated by employing immunoassay-based approaches. Specificity of the identified malaria related serum markers was evaluated by means of analysis of leptospirosis as a febrile control (FC). Compared to HC, 30 and 31 differentially expressed and statistically significant (<em>p</em><0.05) serum proteins were identified in FM and VM respectively, and almost half (46.2%) of these proteins were commonly modulated due to both of the plasmodial infections. 13 proteins were found to be differentially expressed in FM compared to VM. Functional pathway analysis involving the identified proteins revealed the modulation of different vital physiological pathways, including acute phase response signaling, chemokine and cytokine signaling, complement cascades and blood coagulation in malaria. A panel of identified proteins consists of six candidates; serum amyloid A, hemopexin, apolipoprotein E, haptoglobin, retinol-binding protein and apolipoprotein A-I was used to build statistical sample class prediction models. By employing PLS-DA and other classification methods the clinical phenotypic classes (FM, VM, FC and HC) were predicted with over 95% prediction accuracy. Individual performance of three classifier proteins; haptoglobin, apolipoprotein A-I and retinol-binding protein in diagnosis of malaria was analyzed using receiver operating characteristic (ROC) curves. The discrimination of FM, VM, FC and HC groups on the basis of differentially expressed serum proteins demonstrates the potential of this analytical approach for the detection of malaria as well as other human diseases.</p> </div
