Perspectives on barriers to traditional sources of sexual and reproductive health information and services: Are mHealth technologies the answer?

Background: In Ghana, several qualitative studies have explored users' perspectives on conventional sources of sexual and reproductive health (SRH) information and factors which influence provision of and access in rural settings. However, there is a dearth of qualitative studies on healthcare provider (HCP) perspectives on factors that deter access to conventional sources of SRH information among young people in rural Ghana and innovative ways for addressing barriers. This study explored perspectives on barriers to traditional sources of SRH information and services and innovative ways of using mHealth technologies for addressing provision and access challenges among young people in rural Ghana.

Clonality contributes to the spread of Avrainvillea lacerata (Bryopsidales, Chlorophyta) in Hawai'i.

The relative rates of sexual versus asexual reproduction influence the partitioning of genetic diversity within and among populations. During range expansions, asexual reproduction often facilitates colonization and establishment. The arrival of the green alga Avrainvillea lacerata has caused shifts in habitat structure and community assemblages since its discovery in 1981 offshore of O'ahu, Hawai'i.

Worldwide Wellness of Mothers and Babies (WWOMB): program overview and lessons learned from Ethiopia.

Background: Despite the progress made in improving maternal and child health in Ethiopia, it still has one of the highest maternal and neonatal mortality rates in the world. This is largely due to inadequate healthcare infrastructure and a lack of comprehensive evidence-based maternal and reproductive health services. To achieve the Sustainable Development Goal targets related to maternal and child health, it is essential to conduct culturally sensitive and policy-relevant research to identify areas for improvement.

Quiescence and aging of melanocyte stem cells and a novel association with programmed death-ligand 1.

Cellular quiescence is a reversible and tightly regulated stem cell function essential for healthy aging. However, the elements that control quiescence during aging remain poorly defined. Using melanocyte stem cells (McSCs), we find that stem cell quiescence is neither passive nor static.

Effects of short inter-pregnancy/birth interval on adverse perinatal outcomes in Asia-Pacific region: A systematic review and meta-analysis.

Background: Short inter-pregnancy or birth interval is associated with an increased risk of adverse perinatal outcomes. However, some emerging evidence questions this association and there are also inconsistencies among the existing findings. This study aimed to systematically review the evidence regarding the effect of short inter-pregnancy or birth intervals on adverse perinatal outcomes in the Asia-Pacific region.

Comparison of two survey methods for estimating unplanned pregnancy, Bangladesh.

Objective: To compare the prevalence of unintended pregnancy measured by the Demographic and Health Survey (DHS) and the London Measure of Unplanned Pregnancy in Bangladesh, and explore the extent of discordance between the measures and the factors associated with the discordance.

Methods: In 2023, we conducted a cross-sectional survey in four randomly selected districts in Bangladesh: Kurigram, Mymensingh, Pabna and Satkhira. We randomly selected 20 hospitals, five from each district.

Contraceptive counselling and uptake of contraception among women with cardiovascular diseases: a systematic review and meta-analysis.

To address the lack of clarity regarding contraceptive counselling and uptake of contraception among women with cardiovascular disease (CVD), this study aimed to conduct a systematic review and meta-analysis on contraceptive counselling and the subsequent uptake of contraception among women with CVD. A search across six databases identified 1228 articles, with 11 studies (2580 participants) included. The pooled prevalence of contraceptive counselling was 63%, varying from 36 to 94% in individual studies.

Short birth interval in the Asia-Pacific region: A systematic review and meta-analysis.

Background: Short birth interval is associated with an increased risk of adverse health outcomes for mothers and children. Despite this, there is a lack of comprehensive evidence on short birth interval in the Asia-Pacific region. Thus, this study aimed to synthesise evidence related to the definition, classification, prevalence, and predictors of short birth interval in the Asia-Pacific region.

Molecular heterogeneity of quiescent melanocyte stem cells revealed by single-cell RNA-sequencing.

Melanocyte stem cells (McSCs) of the hair follicle are a rare cell population within the skin and are notably underrepresented in whole-skin, single-cell RNA sequencing (scRNA-seq) datasets. Using a cell enrichment strategy to isolate KIT+/CD45- cells from the telogen skin of adult female C57BL/6J mice, we evaluated the transcriptional landscape of quiescent McSCs (qMcSCs) at high resolution. Through this evaluation, we confirmed existing molecular signatures for qMcCS subpopulations (e.

Prognostic models and factors identifying end-of-life in non-cancer chronic diseases: a systematic review.

Background: Precise prognostic information, if available, is very helpful for guiding treatment decisions and resource allocation in patients with non-cancer non-communicable chronic diseases (NCDs). This study aimed to systematically review the existing evidence, examining prognostic models and factors for identifying end-of-life non-cancer NCD patients.

Methods: Electronic databases, including Medline, Embase, CINAHL, Cochrane Library, PsychINFO and other sources, were searched from the inception of these databases up until June 2023.

Effects of short birth interval on child malnutrition in the Asia-Pacific region: Evidence from a systematic review and meta-analysis.

Child malnutrition remains a significant concern in the Asia-Pacific region, with short birth intervals recognised as a potential risk factor. However, evidence of this association is inconclusive. This study aimed to systematically review the existing evidence and assess the summary effects of short birth interval on child malnutrition in the Asia-Pacific region.

Replacement of Dietary Fish Protein with Bacterial Protein Results in Decreased Adiposity Coupled with Liver Gene Expression Changes in Female .

Background: Effective use of as a preclinical model requires standardization of macronutrient sources to achieve scientific reproducibility across studies and labs.

Objective: Our objective was to evaluate a bacterial-based single-cell protein (SCP) for the production of open-source standardized diets with defined health characteristics for the zebrafish research community.

Methods: We completed a 16-wk feeding trial using juvenile 31 d postfertilization (10 tanks per diet and 14 per tank) with formulated diets containing either a typical fish protein ingredient [standard reference (SR) diet] or a novel bacterial SCP source [bacterial protein (BP) diet].

Molecular heterogeneity of quiescent melanocyte stem cells revealed by single-cell RNA-sequencing.

Unlabelled: Melanocyte stem cells (McSCs) of the hair follicle are a rare cell population within the skin and are notably underrepresented in whole-skin, single-cell RNA sequencing (scRNA-seq) datasets.

Through this evaluation, we confirmed existing molecular signatures for qMcCS subpopulations (e.

Irradiation-induced hair graying in mice: an experimental model to evaluate the effectiveness of interventions targeting oxidative stress, DNA damage prevention, and cellular senescence.

Hair graying, also known as canities or achromotrichia, is a natural phenomenon associated with aging and is influenced by external factors such as stress, environmental toxicants, and radiation exposure. Understanding the mechanisms underlying hair graying is an ideal approach for developing interventions to prevent or reverse age-related changes in regenerative tissues. Hair graying induced by ionizing radiation (γ-rays or X-rays) has emerged as a valuable experimental model to investigate the molecular pathways involved in this process.

Short birth interval prevalence, determinants and effects on maternal and child health outcomes in Asia-Pacific region: a systematic review and meta-analysis protocol.

Background: Short birth interval (SBI) has been linked to an increased risk of adverse maternal, perinatal, infant and child health outcomes. However, the prevalence and maternal and child health impacts of SBI in the Asia-Pacific region have not been well understood. This study aims to identify and summarise the existing evidence on SBI including its definition, measurement prevalence, determinants and association with adverse maternal and child health outcomes in the Asia-Pacific region.

Association between maternal high-risk fertility behaviour and perinatal mortality in Bangladesh: Evidence from the Demographic and Health Survey.

Background: High-risk fertility behaviours including pregnancy early or late in the reproductive life course, higher parity and short birth intervals are ongoing concerns in Low- and Middle-Income Countries (LMICs) such as Bangladesh. Although such factors have been identified as major risk factors for perinatal mortality, there has been a lack of progress in the area despite the implementation of the Millennium and Sustatinable Development Goals. We therefore explored the effects of high-risk maternal fertility behaviour on the occurrence of perinatal mortality in Bangladesh.

Australian general practitioners' perspectives on integrating specialist diabetes care with primary care: qualitative study.

Background: Improving the coordination and integration of health services is recognised nationally and internationally as a key strategy for improving the quality of diabetes care. The Australian Diabetes Alliance Program (DAP) is an integrated care model implemented in the Hunter New England Local Health District (HNELHD), New South Wales (NSW), in which endocrinologists and diabetes educators collaborate with primary care teams via case-conferencing, practice performance review, and education sessions. The objective of this study was to report on general practitioners' (GPs) perspectives on DAP and whether the program impacts on their skills, knowledge, and approach in delivering care to adult patients with type 2 diabetes.

Spatial variation in the non-use of modern contraception and its predictors in Bangladesh.

This study aimed to investigate spatial variations in the non-use of modern contraception in Bangladesh and identify associated individual, household, and community-level factors. The analysis utilized data from 16,135 women, extracted from the 2017/18 Bangladesh Demographic and Health Survey. The study's main outcome was the prevalence of non-use of modern contraception (yes or no), while the explanatory variables included factors at the individual, household, and community level.

Effects of lower tiers of government healthcare facilities on unmet need for contraception and contraception use in Bangladesh.

Background: In low- and middle-income countries (LMICs), including Bangladesh, modern contraception use remains lower than desired, resulting in a higher unmet need. A potential factor contributing to lower contraceptive use is reduced access to and use of lower tiers of government healthcare facilities, including home visits by family welfare assistants (FWAs), as well as women's visits to community and satellite clinics. These relationships, however, are still unexplored in Bangladesh and LMICs more broadly.

Replacement of Dietary Fish Protein With Bacterial Single Cell Protein Results in Decreased Adiposity Coupled With Liver Expression Changes in Female Danio Rerio.

Background: Effective use of as a preclinical model requires standardization of macronutrient sources to achieve scientific reproducibility across studies and labs. Our objective was to evaluate single cell protein (SCP) for production of open-source standardized diets with defined heath characteristics for the zebrafish research community. We completed a 16-week feeding trial using juvenile 31 days post-fertilization (dpf) (10 tanks per diet, 14 per tank) with formulated diets containing either a typical fish protein ingredient or a novel bacterial SCP source.

Maternal residential area effects on preterm birth, low birth weight and caesarean section in Australia: A systematic review.

Introduction: In Australia, area of residence is an important health policy focus and has been suggested as a key risk factor for preterm birth (PTB), low birth weight (LBW) and cesarian section (CS) due to its influence on socioeconomic status, access to health services, and its relationship with medical conditions. However, there is inconsistent evidence about the relationship of maternal residential areas (rural and urban areas) with PTB, LBW, and CS. Synthesising the evidence on the issue will help to identify the relationships and mechanisms for underlying inequality and potential interventions to reduce such inequalities in pregnancy outcomes (PTB, LBW and CS) in rural and remote areas.

Distinct cAMP Signaling Microdomains Differentially Regulate Melanosomal pH and Pigmentation.

cAMP signaling is a well-established regulator of melanin synthesis. Two distinct cAMP signaling pathways-the transmembrane adenylyl cyclase pathway, activated primarily by the MC1R, and the soluble adenylyl cyclase (sAC) pathway-affect melanin synthesis. The sAC pathway affects melanin synthesis by regulating melanosomal pH, and the MC1R pathway affects melanin synthesis by regulating gene expression and post-translational modifications.

Patterns of contraceptive use through later reproductive years: A cohort study of Australian women with chronic disease.

Background: Pregnancies among women with chronic disease are associated with poor maternal and fetal outcomes. There is a need to understand how women use or don't use contraception across their reproductive years to better inform the development of preconception care strategies to reduce high risk unintended pregnancies, including among women of older reproductive age. However, there is a lack of high-quality longitudinal evidence to inform such strategies.

Patterns of Labour Interventions and Associated Maternal Biopsychosocial Factors in Australia: a Path Analysis.

In Australia, nearly half of births involve labour interventions. Prior research in this area has relied on cross-sectional and administrative health data and has not considered biopsychosocial factors. The current study examined direct and indirect associations between biopsychosocial factors and labour interventions using 19 years of population-based prospective data.
