Evaluating the impact of a countrywide, market-based roll-out of multiple micronutrient supplementation on low birth weight in Bangladesh: protocol for a two-arm, quasi-experimental and mixed-methods evaluation study.

INTRODUCTION: Multiple micronutrient supplementation (MMS) during pregnancy has a greater potential for reducing the risk of low birth weight (LBW) compared with the standard iron-folic acid supplementation. WHO recently included MMS on their Essential Medicines List. The Social Marketing Company (SMC) in Bangladesh is implementing a countrywide, market-based roll-out of MMS to pregnant women. We aimed to evaluate the implementation of the supplementation programme and its impact on reducing LBW. METHODS AND ANALYSIS: A two-arm, quasi-experimental and mixed-methods evaluation design will be used to evaluate the impact of this 36-month roll-out of MMS. In the intervention areas, pregnant women will purchase MMS products from the SMC's pharmacy networks. Pregnant women in comparison areas will not be exposed to this product until the end of the study. We will collect 4500 pregnant women's data on anthropometric, socioeconomic, nutrition-related and relevant programme indicators during recruitment and bimonthly follow-up until the end of their pregnancy. We will measure children's birth weight within 72 hours of birth and evaluate the changes in LBW prevalence. We will observe market-based MMS service delivery-related conditions of the pharmacies and the quality of the provider's service delivery. Concurrently, we will carry out a process evaluation to appraise the programme activities and recommend course correction. Cluster-adjusted multivariable logistic regression or log-binomial regression analysis of quantitative outcome data will be performed. For qualitative data, we will follow a thematic analysis approach. We will consolidate our study findings by triangulating the data derived from different methods. ETHICS AND DISSEMINATION: This study received ethical approval from the institutional review board of icddr,b (PR number 21001). We will recruit eligible participants after obtaining their informed written/verbal consent (and assent where needed) with full disclosure about the study. The results will be disseminated through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT05108454.

Role of Music Therapy in Traumatic Brain Injury: A Systematic Review and Meta-analysis.

INTRODUCTION: Music therapy has promising results in improving rehabilitation outcomes of patients with various neurologic disorders; however, its effectiveness in patients with traumatic brain injury (TBI) is not clear. METHODS: A search that compared the effect of music therapy as rehabilitation to controls in motor and cognitive outcomes in patients with TBI was carried out. The outcome of interest were gait velocity, stride length, and cadence to determine the motor outcome. Memory and executive function were the main cognitive outcome measures assessed. Two authors independently abstracted data using a data collection form. Results from the studies were then pooled when appropriate for the meta-analysis. RESULTS: Of 102 studies, 6 studies were identified for systematic review and meta-analysis after inclusion and exclusion criteria. The effect of music therapy had a pooled mean difference in improvement in gait velocity by 12.29 cm/second (95% confidence interval 2.31-22.27;), cadence by 7.19 steps/minute (95% confidence interval -25.35 to 39.73;), and stride length by 0.19 meters (95% confidence interval 0.13-0.12;). No serious side effects were noticed, however, one of the studies reported a decrease in memory function after music therapy. CONCLUSIONS: Pooled results from 6 studies demonstrated statistically significant improvement in the stride length and executive function outcome in patients with TBI after music therapy rehabilitation. The improvement effect on cadence and gait velocity was not statistically significant and no significant effect of music therapy was found on memory in these patients.

An Investigation of Factors Influencing High Usage of Medical and Long-Term Care Services in an Aging Society in Japan.

Medical and long-term care costs are increasing all over the world. In this study, we investigated the characteristics of groups with high cost of medical and long-term care to define targets for curbing social security costs. As a result, for the population covered by the National Health Insurance, a large portion of medical costs were incurred for mental disorders, malignant neoplasms, and lifestyle-related diseases. For those covered by the Late Elderly Health Insurance System, most medical costs were incurred for lifestyle-related diseases, femoral fractures, neurological diseases, mental disorders, pneumonia, malignant neoplasms, and Alzheimer's disease. From multiple regression analysis, the hospitalization days, use of advanced medical treatment, outpatient days, and high long-term care level influenced the increased costs. On the other hand, disease characteristics had only a very low effect. These findings suggest that the target population has complex medical and long-term care needs because they have multiple diseases.
