Bridging the gap: glucose transporters, Alzheimer's, and future therapeutic prospects.

Glucose is the major source of chemical energy for cell functions in living organisms. The aim of this mini-review is to provide a clearer and simpler picture of the fundamentals of glucose transporters as well as the relationship of these transporters to Alzheimer's disease. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Electronic databases (PubMed and ScienceDirect) were used to search for relevant studies mainly published during the period 2018-2023. This mini-review covers the two main types of glucose transporters, facilitated glucose transporters (GLUTs) and sodium-glucose linked transporters (SGLTs). The main difference between these two types is that the first type works through passive transport across the glucose concentration gradient. The second type works through active co-transportation to transport glucose against its chemical gradient. Fluctuation in glucose transporters translates into a disturbance of normal functioning, such as Alzheimer's disease, which may be caused by a significant downregulation of GLUTs most closely associated with insulin resistance in the brain. The first sign of Alzheimer's is a lack of GLUT4 translocation. The second sign is tau hyperphosphorylation, which is caused by GLUT1 and 3 being strongly upregulated. The current study focuses on the use of glucose transporters in treating diseases because of their proven therapeutic potential. Despite this, studies remain insufficient and inconclusive due to the complex and intertwined nature of glucose transport processes. This study recommends further understanding of the mechanisms related to these vectors for promising future therapies.

Scaling up Kangaroo Mother Care in Ethiopia and India: a multi-site implementation research study.

OBJECTIVES: Kangaroo Mother Care (KMC), prolonged skin-to-skin care of the low birth weight baby with the mother plus exclusive breastfeeding reduces neonatal mortality. Global KMC coverage is low. This study was conducted to develop and evaluate context-adapted implementation models to achieve improved coverage. DESIGN: This study used mixed-methods applying implementation science to develop an adaptable strategy to improve implementation. Formative research informed the initial model which was refined in three iterative cycles. The models included three components: (1) maximising access to KMC-implementing facilities, (2) ensuring KMC initiation and maintenance in facilities and (3) supporting continuation at home postdischarge. PARTICIPANTS: 3804 infants of birth weight under 2000 g who survived the first 3 days, were available in the study area and whose mother resided in the study area. MAIN OUTCOME MEASURES: The primary outcomes were coverage of KMC during the 24 hours prior to discharge and at 7 days postdischarge. RESULTS: Key barriers and solutions were identified for scaling up KMC. The resulting implementation model achieved high population-based coverage. KMC initiation reached 68%-86% of infants in Ethiopian sites and 87% in Indian sites. At discharge, KMC was provided to 68% of infants in Ethiopia and 55% in India. At 7 days postdischarge, KMC was provided to 53%-65% of infants in all sites, except Oromia (38%) and Karnataka (36%). CONCLUSIONS: This study shows how high coverage of KMC can be achieved using context-adapted models based on implementation science. They were supported by government leadership, health workers' conviction that KMC is the standard of care, women's and families' acceptance of KMC, and changes in infrastructure, policy, skills and practice.

Early initiation of breastfeeding, colostrum avoidance, and their associated factors among mothers with under one year old children in rural pastoralist communities of Afar, Northeast Ethiopia: a cross sectional study.

BACKGROUND: Early initiation of breastfeeding (EIBF) is defined as initiation of breastfeeding within 1 h of birth. This is also the time colostrum is secreted with its potential benefits. Globally, two out of five under 5 children die in the first month of life, more than a third of which being on the first day. Neonatal mortality is still a major health problem in Ethiopia. EIBF and colostrum feeding are associated with decreased neonatal morbidity and mortality. With this study, we aim to determine the magnitude and factors associated with EIBF and colostrum avoidance. METHODS: A community based cross-sectional study was conducted from May to June 2016 on 390 mothers in Afar region. Bivariate logistic regression was used to identify the association between the independent and the outcome variables. Multivariable logistic regression was used to determine the independent predictors of EIBF and colostrum avoidance. The strength of the association was measured by odds ratio and 95% confidence interval, and p-value < 0.05 was considered statistically significant. Hosmer and Lemeshow test was used to test model goodness of fitness and multi-collinearity between independent variables was checked. RESULTS: About 248(63.6%) respondents initiated breastfeeding within 1 h of birth. Mothers whose delivery was attended by a health professional had 4.75 times higher odds (AOR 4.75; 95% CI 1.71, 13.19) of EIBF as compared to those who were attended by others. Trust on nurses to provide pregnancy care (AOR 5.59; 95% CI 1.05, 29.8) was significantly associated with EIBF. About 300(76.9%) respondents discarded colostrum. Mothers who had no discussion with TBA on child nutrition were 6.6 times (AOR 6.63; 95% CI 1.43, 30.63) more likely to avoid colostrum than their counterparts. CONCLUSION: More than one-third of infants didn't start breastfeeding within 1 h of birth and three-fourth of the mothers discarded colostrum. Therefore, it is important to develop and/or strengthen services/advice on EIBF including colostrum feeding. Promoting delivery by health professionals, discussion on child nutrition and building trust between mothers and health professionals can be important community interventions to encourage EIBF and colostrum feeding.

Knowledge and skills retention among frontline health workers: community maternal and newborn health training in rural Ethiopia.

INTRODUCTION: We examined the degree to which the skills and knowledge of health workers in Ethiopia were retained 18 months after initial maternal and newborn health training and sought to identify factors associated with 18-month skills assessment performance. METHODS: A nonexperimental, descriptive design was employed to assess 18-month skills performance on the topics of Prevent Problems Before Baby Is Born and Prevent Problems After Baby Is Born. Assessment was conducted by project personnel who also received the maternal and newborn health training and additional training to reliably assess health worker performance. RESULTS: Among the 732 health workers who participated in maternal and newborn health training in 6 rural districts of the Amhara and Oromia regions of Ethiopia (including pretesting before training and a posttraining posttest), 75 health extension workers (78%) and 234 guide team members (37%) participated in 18-month posttest. Among health extension workers in both regions, strong knowledge retention was noted in 10 of 14 care steps for Prevent Problems Before Baby Is Born and in 14 of 16 care steps of Prevent Problems After Baby Is Born. Lower knowledge retention was observed among guide team members in the Amhara region. Across regions, health workers scored lowest on steps that involved nonaction (eg, do not give oxytocin). Educational attainment and age were among the few variables found to significantly predict test performance, although participants varied substantially by other sociodemographic characteristics. DISCUSSION: Results demonstrated an overall strong retention of knowledge and skills among health extension workers and highlighted the need for improvement among some guide team members. Refresher training and development of strategies to improve knowledge of retention of low-performing steps were recommended.

The effect of community maternal and newborn health family meetings on type of birth attendant and completeness of maternal and newborn care received during birth and the early postnatal period in rural Ethiopia.

INTRODUCTION: Maternal and newborn deaths occur predominantly in low-resource settings. Community-based packages of evidence-based interventions and skilled birth attendance can reduce these deaths. The Maternal and Newborn Health in Ethiopia Partnership (MaNHEP) used community-level health workers to conduct prenatal Community Maternal and Newborn Health family meetings to build skills and care-seeking behaviors among pregnant women and family caregivers. METHODS: Baseline and endline surveys provided data on a random sample of women with a birth in the prior year. An intention-to-treat analysis, plausible net effect calculation, and dose-response analysis examined increases in completeness of care (mean percentage of 17 maternal and newborn health care elements performed) over time and by meeting participation. Regression models assessed the relationship between meeting participation, completeness of care, and use of skilled providers or health extension workers for birth care-controlling for sociodemographic and health service utilization factors. RESULTS: A 151% increase in care completeness occurred from baseline to endline. At endline, women who participated in 2 or more meetings had more complete care than women who participated in fewer than 2 meetings (89% vs 76% of care elements; P < .001). A positive dose-response relationship existed between the number of meetings attended and greater care completeness (P < .001). Women with any antenatal care were nearly 3 times more likely to have used a skilled provider or health extension worker for birth care. Women who had additionally attended 2 or more meetings with family members were over 5 times as likely to have used these providers, compared to women without antenatal care and who attended fewer than 2 meetings (odds ratio, 5.19; 95% confidence interval, 2.88-9.36; P < .001). DISCUSSION: MaNHEP's family meetings complemented routine antenatal care by engaging women and family caregivers in self-care and care-seeking, resulting in greater completeness of care and more highly skilled birth care.

Use of mobile video show for community behavior change on maternal and newborn health in rural Ethiopia.

INTRODUCTION: A number of factors affect Ethiopia's efforts to meet Millennium Development Goals 4 and 5 to reduce maternal and newborn mortality. The Maternal and Newborn Health in Ethiopia Partnership (MaNHEP) project, as part of its overall strategy, implemented behavior change communication interventions to increase women's demand for and use of antenatal, birth, and postnatal services. Seeking to reach "media-dark" areas, MaNHEP implemented a mobile video show focused on maternal and newborn health. We report on the effect of the mobile video show on community knowledge, attitudes, and beliefs regarding maternal and newborn health, especially regarding care-seeking behavior and use of a skilled attendant for birth and postnatal care. METHODS: Two main data sources are used: qualitative data gathered through mobile video show participant discussions in 31 randomly selected kebeles (villages with about 1000 households) and focus groups in 4 kebeles (2 from each region), and quantitative data generated from 510 randomly selected adults participating in MaNHEP's endline survey. Qualitative data were thematically analyzed by the research team, and the accuracy of the transcriptions and categorization was also checked. RESULTS: The mobile video show reached a total of 28,389 mostly young or adult females in 51 kebeles. At endline, mobile video show attendees (vs nonattendees) reported significantly (P < .001) higher rates of recall of key MaNHEP messages about use of health extension workers for pregnancy registration, labor and birth notification, and postnatal care. Qualitative analysis yielded 3 overarching themes: mirrors to the community (the portrayal is accurate); call to action (we have to change this); and improvement ideas (suggested positive actions). DISCUSSION: The entertaining nature and local organization of the mobile video show event encouraged attendance. Building the video around recognizable characters (particularly the husbands) contributed to bringing about desired changes in people's knowledge and beliefs. Making the show readily available (through the mobile van) and bundling it with facilitated reflection sessions had a considerable impact on people's knowledge and confidence.

Building district-level capacity for continuous improvement in maternal and newborn health.

INTRODUCTION: The Maternal and Newborn Health in Ethiopia Partnership (MaNHEP) adapted a collaborative improvement strategy to develop woreda (district) leadership capacity to support and facilitate continuous improvement of community maternal and neonatal health (CMNH) and to provide a model for other woredas, dubbed "lead" woredas. Community-level quality improvement (QI) teams tested solutions to improve CMNH care supported by monthly coaching and regular meetings to share experiences. This study examines the extent of the capacity built to support continuous improvement in CMNH care. METHODS: Surveys and in-depth interviews assessed the extent to which MaNHEP developed improvement capacity. A survey questionnaire evaluated woreda culture, leadership support, motivation, and capacity for improvement activities. Interviews focused on respondents' understanding and perceived value of the MaNHEP improvement approach. Bivariate analyses and multivariate linear regression models were used to analyze the survey data. Interview transcripts were organized by region, cadre, and key themes. RESULTS: Respondents reported significant positive changes in many areas of woreda culture and leadership, including involving a cross-section of community stakeholders (increased from 3.0 to 4.6 on 5-point Likert scale), using improvement data for decision making (2.8-4.4), using locally developed and tested solutions to improve CMNH care (2.5-4.3), demonstrating a commitment to improve the health of women and newborns (2.6-4.2), and creating a supportive environment for coaches and QI teams to improve CMNH (2.6-4.0). The mean scores for capacity were 3.7 and higher, reflecting respondents' agreement that they had gained capacity in improvement skills. Interview respondents universally recognized the capacity built in the woredas. The themes of community empowerment and focused improvement emerged strongly from the interviews. DISCUSSION: MaNHEP was able to build capacity for continuous improvement and develop lead woredas. The multifaceted approach to building capacity was critical for the success in creating lead woredas able to serve as models for other districts.
