Probiotics supplementation or probiotic-fortified products on sarcopenic indices in older adults: systematic review and meta-analysis from recent randomized controlled trials.

Introduction: A noteworthy correlation was seen between changes in the gut microbiome and sarcopenia in older adults. Along with increasing research on probiotic supplementation for various medical problems, we aimed to obtain evidence and summarize the effect of probiotic supplementation on sarcopenic indices among older adults. Methods: We utilized PubMed, EBSCO, and Proquest, in addition to manual search using synonyms and variation for 'probiotic,' 'sarcopenia,' and 'older adults.' Randomized controlled trials investigated the utilization of probiotics or probiotic-containing products in older adults with sarcopenic indices including muscle mass and strength. The random-effects model was applied to the meta-analysis process. Results: Seven studies were obtained with 733 pooled older adults. Probiotic supplementation resulted in a significant increase of muscle mass with adjusted SMD (Standardized Mean Difference) of 0.962 (95% CI: 0.288 to 1.635, p = 0.049) using till and trim analysis and muscle strength with SMD of 1.037 (95% CI: 0.077 to 1.996, p = 0.03). However, both outcomes were associated with significantly high heterogeneity (I2 = 89.5% and I2 = 89.9%, respectively). Conclusion: When opposed to a placebo, the probiotic treatment improved the amount of muscle and its endurance based on recent evidence, however, further studies should be done with larger samples and targeted populations.

Mode of HIV exposure and excess burden of neurocognitive impairment in people living with HIV: a protocol for systematic review and meta-analysis of controlled studies.

BACKGROUND: Chronic HIV infection significantly elevates the risk of brain pathology, precipitating neurocognitive impairment (NCI) among people living with HIV (PLWH). The diagnosis of NCI in PLWH hinges on evaluating deviations in neuropsychological test performance in comparison to HIV-seronegative normative controls. However, the adverse psychosocial conditions experienced by PLWH can also result in reduced test performance, potentially confounding the accurate NCI attribution to HIV infection. This planned systematic review aims to investigate potential disparities in the excess burden of NCI among PLWH in two groups of studies: (a) studies enrolling controls who shared a similar mode of HIV exposure (MoHE) with the PLWH participants (MoHE-adjusted) and (b) studies enrolling normative controls or controls without undefined MoHE (MoHE-naive). METHODS: We will systematically search five electronic databases (MEDLINE, Embase, PsycINFO, Web of Science, ProQuest) and registries (OpenGrey, ClinicalTrials.gov, ISRCTN registry). Studies reporting NCI in PLWH and HIV-seronegative controls with cross-sectional or baseline measurements, published from January 2007 to September 2023, will be included. To be classified as MoHE adjusted, a study must evidence ≥ 90% enrolment of both PLWH and their seronegative controls from the same MoHE group (e.g. men who have sex with men, people who use drugs or alcohol). Reports of test performance scores will be transformed into NCI proportions using simulated score distributions, applying a global deficit score cut-off ≥ 0.5 to estimate NCI cases. The Newcastle-Ottawa scale adapted to the purpose of the review will be used to appraise study quality. Random-effects meta-analysis will be used to pool the excess burden of NCI in prevalence ratios and test the difference between MoHE-adjusted and MoHE-naive studies. Furthermore, subgroup analyses and meta-regression will be undertaken across categorical study-level covariates (e.g. study locations, NCI diagnostic criteria) and continuous/ordinal covariates (nadir CD4, number of neurocognitive domains assessed), respectively. DISCUSSION: This systematic review will contribute towards a greater appreciation of the unique psychosocial conditions of PLWH that are missing from the current case definition of HIV-associated neurocognitive disorder. The findings will additionally highlight possible disparities in the distribution of the excess burden of NCI by MoHE groups, thereby guiding the prioritization of mitigation efforts.

Correlation between health status and academic achievement among elementary school students in North Jakarta.

BACKGROUND: High-performing students are essential investments in building the nation's future. In Indonesia, however, the correlation between students' health and academic achievement is rarely examined. This study aimed to evaluate primary school students' health status and its relation to their academic achievement. MATERIAL AND METHODS: A survey was conducted on 1335 students from four primary schools in North Jakarta. Health assessments included nutritional status, hair, skin condition, dental, vision, and ear conditions. Parents filled sociodemographic questionnaire. Mid-exam scores in core subjects determined academic achievement. Data were analyzed using binomial logistic regression to determine the relation of health status with students' academic achievement. RESULTS: In the younger group, students who were stunted (adjusted odds ratio [AOR] 2.23, 95% CI: 1.11-4.50), had dental caries (AOR 2.16, 95% CI: 1.15-4.04), hair problems (AOR 2.04, 95% CI: 1.15-3.59), and skin problems (AOR 1.49, 95% CI: 1.01-2.20) were more likely to have a low-performing index. In the older group, students with hair problems tend to have a low-performing index (AOR 3.05, 95% CI: 1.88-5.89). Meanwhile, the students who wore eye glasses were more likely to achieve a high-performing index in the older group (AOR 0.60, 95% CI: 0.50-0.78). CONCLUSION: This study shows a significant correlation between students' health status and academic achievement, where students with health problems were more likely to have lower grades compared to their counterparts. Regular health screening and examination are vital to maintaining students' health; therefore, their academic achievement can be increased.

Adapting the World Health Organization iSupport Dementia program to the Indonesian socio-cultural context.

Background: Providing care for people with dementia (PwD) without sufficient understanding of the condition might negatively affect the wellbeing of the caregivers, given the lengthy care and progressive nature of the disease. The iSupport for dementia developed by World Health Organization (WHO) is a self-administered training manual for caregivers of PwD, adaptable to local cultures and contexts. This manual needs translation and adaptation to produce a culturally appropriate version for use in Indonesia. This study reports the outcomes and lessons learnt from our translation and adaptation of iSupport content into Bahasa Indonesia. Methods: The original iSupport content was translated and adapted using the WHO iSupport Adaptation and Implementation Guidelines. The process included forward translation, expert panel review, backward translation, and harmonization. The adaptation process included Focus Group Discussions (FGD), involving family caregivers, professional care workers, professional psychological health experts, and Alzheimer's Indonesia representatives. The respondents were asked to express their opinions about the WHO iSupport program, which comprises five modules and 23 lessons covering well-established topics on dementia. They were also asked to suggest improvements and their personal experiences compared to the adaptations applied in the iSupport. Results: Two experts, 10 professional care workers, and eight family caregivers participated in the FGD. Overall, all participants had positive views of the iSupport material. The expert panel identified the need to reformulate definitions, recommendations, and local case studies to fine-tune the original contents to local knowledge and practices. Based on the feedback in the qualitative appraisal, several improvements regarding the language and diction, additional relevant and concrete examples, personal names and cultural habits, and customs and traditions were addressed. Conclusions: The translation and adaptation of the iSupport into the Indonesian context have shown some changes needed to make the iSupport content culturally and linguistically appropriate for Indonesian end users. In addition, given the broad spectrum of dementia, various case illustrations have been added to improve the understanding of care in particular situations. Future studies are needed to evaluate the efficacy of the adapted iSupport in improving the quality of life of PwD and their caregivers.

Rapid transition between SARS-CoV-2 variants of concern Delta and Omicron detected by monitoring municipal wastewater from three Canadian cities.

Monitoring the communal incidence of COVID-19 is important for both government and residents of an area to make informed decisions. However, continuous reliance on one means of monitoring might not be accurate because of biases introduced by government policies or behaviours of residents. Wastewater surveillance was employed to monitor concentrations of SARS-CoV-2 RNA in raw influent wastewater from wastewater treatment plants serving three Canadian Prairie cities with different population sizes. Data obtained from wastewater are not directly influenced by government regulations or behaviours of individuals. The means of three weekly samples collected using 24 h composite auto-samplers were determined. Viral loads were determined by RT-qPCR, and whole-genome sequencing was used to charaterize variants of concern (VOC). The dominant VOCs in the three cities were the same but with different proportions of sub-lineages. Sub-lineages of Delta were AY.12, AY.25, AY.27 and AY.93 in 2021, while the major sub-lineage of Omicron was BA.1 in January 2022, and BA.2 subsequently became a trace-level sub-variant then the predominant VOC. When each VOC was first detected varied among cities; However, Saskatoon, with the largest population, was always the first to present new VOCs. Viral loads varied among cities, but there was no direct correlation with population size, possibly because of differences in flow regimes. Population is one of the factors that affects trends in onset and development of local outbreaks during the pandemic. This might be due to demography or the fact that larger populations had greater potential for inter- and intra-country migration. Hence, wastewater surveillance data from larger cities can typically be used to indicate what to expect in smaller communities.
