Background Early and exclusive breastfeeding have been shown to protect young infants from all-cause and diarrhoea-related mortality. Ideally breastfeeding should be initiated within the first hour of birth. Despite efforts to increase rates of early and exclusive breastfeeding in low- and middle-income countries (LMICs), challenges with uptake remain. This analysis reviews trends in early and exclusive breastfeeding, and the impact of infant feeding interventions in reducing childhood diarrhoea. Methods We conducted a detailed review of articles written in English between 1990 and 2020 on the impact and efficacy of breastfeeding and complementary feeding on diarrhoea in children aged 0-2 years in LMICs. Using data from 86 countries and all WHO global regions collected from the mid-1980s through 2018 obtained from publicly available Demographic Health Surveys, we assessed trends in five-year intervals of timing of breastfeeding initiation, exclusive breastfeeding, median and mean duration of exclusive breastfeeding, and complementary feeding. Results The literature search identified ten articles that described variable rates of early initiation of breastfeeding from 20% in Pakistan to 76% in Egypt. An analysis of 288 DHS studies found that the proportion of women who reported initiating breastfeeding within an hour of birth increased from 32% in the early 1990s to 55% between 2016 and 2020. Exclusive breastfeeding increased from 20% in the late 1980s to 48% between 2016 and 2020 and the mean duration of exclusive breastfeeding of 2-to-4-month-old infants doubled. Early initiation of breastfeeding and exclusive breastfeeding was associated with reductions in diarrhoea prevalence in the South East Asian, Western Pacific, Eastern Mediterranean, and African regions. Eight studies evaluating the effectiveness of different maternal education interventions, health care worker training, and media campaigns demonstrated improvements in exclusive breastfeeding, and most resulted in reductions in the incidence or duration of diarrhoea. Conclusions During the last two decades, early and exclusive breastfeeding have increased. Nevertheless, the uptake of this basic, low-cost intervention remains suboptimal across all global regions. Given the potential benefits the in reduction of diarrhoea and diarrhoea-associated mortality, interventions for improving the uptake of early and exclusive breastfeeding in different sociological contexts need to be designed, implemented, and evaluated.

Background Services for the preclinical development and evaluation of cardiovascular implant devices (CVIDs) is a new industry. However, there is still no indicator system for quality evaluation. Our aim is to construct a service for quality evaluation system for the preclinical research and development of CVIDs based on Fuzzy Analytical Hierarchy Process (FAHP). Methods First, we reviewed the related literature to identify and select possible factors. Second, we developed an analytic hierarchy process framework. Third, we developed a questionnaire based on pairwise comparisons and invited 10 experienced specialists to rate these factors. We then used FAHP to compute the weights of these factors and prioritize them. Finally, to demonstrate the effectiveness of the proposed indicator system, a case study was performed as a practical example. Results Four main indicators (professionalism, functionality, stability and security) and 15 subindicators were selected to form the service evaluation system based on literature review and expert’s proposals. According to the weight calculation data, the order of primary indicators by importance, is professionalism (0.6457), security (0.1193), functionality (0.0958) and stability (0.0596) in sequence. Top five secondary indices are personnel’s technical ability, facility and equipment attractiveness, data auditability, confidentiality capability and professional service procedures. In the case study, FW’s final actual effectiveness value was 0.9076, which is the same as the actual situation. Conclusion The indicator system established in this study is comprehensive, reasonable, reliable and with strong practicality. It is worth popularizing and applying. The implementation of this evaluation system can provide measurable evidence for service demander and a way to improve service quality for suppliers.

Perinatal hypoxic-ischemic encephalopathy (HIE), known as birth asphyxia, remains a major contributor to poor neurodevelopmental outcomes including cerebral palsy and seizures. One striking feature of HIE injury is a delayed progression of neuronal degeneration that spreads over time from the most severely damaged areas outward into neighboring undamaged regions. There is increasing evidence that these lesions act as sites of origin for waves of spreading depression (SD), a wave of neuronal and glial depolarization, that progressively enlarge the brain lesions. While the pathophysiology of SD is still under debate, there is increasing evidence that purinergic receptors in conjunction with connexin and pannexin 1 channels are necessary for sustained propagation of the waves and neuroinflammation. This review intends to discuss the relative contribution of purinergic signaling and connexin and pannexin 1 channels to trigger and spread SD waves leading to the development of progressive brain lesions under conditions of perinatal HIE.

Objective: Disrespectful and abusive (D&A) maternity care is a deterrent to facility childbirth and can thus contribute to child and maternal mortality. This study will review existing literature on D&A in Tanzania to better understand and contextualize the issue. Methods: A comprehensive literature search was conducted to find relevant publications on D&A during childbirth in Tanzania. The search was conducted on the National Center for Biotechnology Information (NCBI) and PubMed (U.S. National Library of Medicine at the National Institutes of Health). The inclusion criteria were as follows: qualitative, quantitative, and ethnographic studies conducted in Tanzania on obstetrical violence; published in English; focused on prevalence, incidence, root causes, historical trends, interventions, and policy recommendations for obstetrical violence in Tanzania. Results: Twenty-one studies were selected for this literature review. Up to 73.1% of women reported experiencing at least one form of D&A during labor. Commonly reported D&A events include non-dignified care, non-confidential care, and physical abuse. Other forms of D&A, including detention in facilities and asking for unofficial payments, are also reported. Ninety-six percent of nurses, midwives, and nursing assistants in Tanzania self-reported engaging in at least one form of D&A. Lack of training and provider support, long work hours, fear of blame, and limited infrastructure were reported as factors leading to D&A by providers. Conclusions: In Tanzania, D&A during childbirth is prevalent in healthcare systems. The direct relationship between D&A and poor maternal and fetal health is well-documented.
