Abstract Background Timely initiation of breastfeeding is crucial for positive health outcomes for babies and mothers. Understanding the factors influencing timely initiation of breastfeeding is vital for reducing child morbidities and mortalities in Mauritania. This study, therefore, assessed the prevalence of early initiation of breastfeeding and its associated factors among women in Mauritania, providing significant insights for improving maternal and child health in the country. Methods We performed a secondary analysis of the 2019–2021 Mauritania Demographic and Health Survey data. A weighted sample of 4,114 mother-child pairs was included in the study. We used percentage to present the prevalence of early initiation of breastfeeding. A four-modelled multilevel binary logistic regression was used to examine the factors associated with early initiation of breastfeeding. The regression results were presented using adjusted odds ratio (aOR) with their respective 95% confidence interval (CI). Stata software version 17.0 was used to perform all the analyses. Results The prevalence of early initiation of breastfeeding was 57.3% (95% CI 54.5, 60.00). Birth order was associated with early initiation of breastfeeding with the highest odds among those in the fourth birth order (aOR 1.61; 95% CI 1.08, 2.39). Mothers who practiced skin-to-skin contact were more likely to initiate breastfeeding early than those who did not (aOR 1.46; 95% CI 1.14, 1.87). There were regional disparities in the early initiation of breastfeeding. The odds of timely initiation of breastfeeding was lower among women who were delivered by caesarean section (aOR 0.22; 95%CI 0.14, 0.36), those who were working (aOR 0.57; 95% CI 0.45, 0.73), those who had four or more antenatal care visits (aOR 0.67; 95%CI 0.47, 0.94)], and those in the richest wealth quintile (aOR 0.61; 95% CI 0.38, 0.98) compared to those who had normal delivery, those who were not working, those who had zero antenatal care visits, and those in the poorest wealth quintile households, respectively. Conclusion Our study found a relatively low prevalence of early initiation of breastfeeding among women in Mauritania. Factor such as birth order, region of residence, mother and newborn skin-to-skin contact after birth, antenatal care visits, caesarean delivery, employment status, and wealth index were associated with early initiation of breastfeeding. Improving optimal breastfeeding practices, such as early initiation of breastfeeding in Mauritania, should be given adequate attention. There is a need for interventions such as baby-friendly facilities, providing an enabling environment for mothers to breastfeed their newborns early. Addressing regional health access disparities is important to improve early initiation of breastfeeding and other maternal, newborn, and child health interventions.

Objective: To study ultrasound findings of children with dengue and analyze the possible correlation between ultrasound findings and severity of dengue in children. Methods: This retrospective study, which was conducted over one year, analyzed 50 pediatric dengue patients. Ultrasound findings such as gallbladder wall edema, pleural effusion and ascites were assessed. Cases were categorized into dengue without warning signs, dengue with warning signs, and severe dengue according to the World Health Organization's classification of dengue. Correlation between ultrasound abnormalities, severity of dengue, and thrombocytopenia were analyses. A p-value of less than 0.05 was taken as statistically significant. Results: Of 50 pediatric patients diagnosed with dengue participated in this study, 72% were boys, and 28% were girls with a male-to-female ratio of 1:0.38. Fever was the most frequent symptom (100%), followed by nausea/vomiting (84%) and body ache/myalgia (78%). Ultrasound findings revealed that gallbladder wall edema (48%), pleural effusion (44%), and ascites (50%) were significantly associated with severe dengue and dengue with warning signs (p

Background: There is evidence that engaging in research is directly associated with better performance. If this relationship is to be strengthened, it is necessary to understand the mechanisms that might underlie that relationship. Aim: To explore the perspectives of staff and wider stakeholders about mechanisms by which research activity may impact on the performance of general practices. Design & setting: Qualitative study using semi-structured interviews with general practice professionals and wider stakeholders in England. Method: Individual interviews with 41 purposively sampled staff in ‘research-ready’ or ‘research-active’ general practices, and 21 other stakeholders. Interviews were independently coded by three researchers using a framework approach. Results: Participants described potential ‘direct’ and ‘indirect’ impacts on their work. ‘Direct’ impacts included improved knowledge and skills that could change practice work (for example, additional records searches for particular conditions); bringing in additional resources (for example, access to investigations or staff); and improving relationships with patients. ‘Indirect’ impacts included job satisfaction (for example, perception of practice as a centre of excellence and innovation, and the variety afforded by research activity reducing burnout); and staff recruitment (increasing the attractiveness of the practice as a place to work). Responders identified few negative impacts. Conclusion: Staff and stakeholders identified a range of potential impacts of research activity on practice performance, with impacts on their working lives most salient. Negative impacts were not generally raised. Nevertheless, responders generally discussed potential impacts rather than providing specific examples of those impacts. This may reflect the type of research activity conducted in general practice, often led by external collaborators.

Background. The study of the value-meaning aspect of notions of professional responsibility is due to their potential impact on the efficiency of work and on psychological well-being of a specialist. The analysis of literary sources showed insufficient development of the emotional component of the studied phenomenon. Objectives. The article focuses on carrying out a structural and informative analysis of the views of Internet users on professional responsibility as well as on selecting value-meaning factors from the general context of representations. Study Participants. Users of the social network VKontakte and specialized Internet forums participated in the study. The number of author’s texts analysed was 1010. Each participant submitted one communication, i.e. the number of participants corresponds to the number of texts and amounts to 1,010 people. The total number of messages included 800 texts from the social network and 210 texts from the Internet forums. Methods. The study of ordinary representations of Internet users about professional responsibility is conducted with the help of statistical analysis of word occurrence frequency (PyMorphy2). Classification of the analyzed units (nouns, verbs, adjectives) is made on the basis of statistical processing and expert evaluation, structural elements of the phenomenon of “professional responsibility” and its value-meaning characteristics are shown. The analysis of contingency on the basis of testing with corpus of Russian language dataset RuTweetCorp, based on Bernoulli distribution, neuronetwork model of analysis of emotional background of messages (FastText), neuronetwork model Dostoevsky and dataset RuSentiment. Results. The conducted analysis allowed to present the structure of “professional responsibility”, to reveal cognitive, emotional, and behavioral components. The study identified a fourth meta-structural component, never previously identified by other authors, which is related to the “God” construct. The value-meaning patterns of professional responsibility have been identified and described. The analysis of the emotional background of the messages made it possible to highlight the trend towards negative assessments of the phenomenon of “professional responsibility” at the current stage of society development. Conclusions. The approach proposed in the study allows to reveal the psychological essence of professional responsibility, to highlight the importance of the emotional component in the strategies of acceptance/avoidance of responsibility. The equation of professional responsibility with personal responsibility of a specialist has been revealed, while the notions of national, social, and corporate responsibility are manifested insignificantly. The study of professional responsibility through the value-meaning aspect can become the basis for analysis of social behavior in a person as a whole in the future.

Biodiesel from vegetable or animal feedstock can serve as a suitable source for renewable energy. This study utilized heterogeneous catalyst obtained from fish bone for biodiesel production from raw cat fish waste (CFW) oil. The CFW oil yield obtained using wet reduction extraction method was 96.85 %. The heterogeneous catalyst was prepared by calcination at 600 °C, for 4 h and characterized using SEM-EDX. Catalyst characterization showed suitable elements that can improve the catalytic activity. Physiochemical characterization results showed that viscosity of CFW oil (48.782 mm2/s), reduced to 9.391 mm2/s in the produced biodiesel. Similarly, after transesterification free fatty acid (3.593 mg/KOH/Kg) and acid value (7.186 mg/KOH/Kg) of CFW oil reduced to 1.48 mg/KOH/Kg and 2.96 mg/KOH/Kg, respectively, in the biodiesel. Finding from the Fourier Transform Infrared (FTIR) Spectrum of the raw CFW oil showed the presence of –OH and was assigned to the axial deformation of water molecule. However, the –OH group disappeared in the FTIR spectrum of biodiesel due to the transesterification process. This observation is consistent with the findings for moisture contents of raw CFW oil (0.073 %) and biodiesel (0.00 %), which showed disappearance of water after transesterification. The biodiesel yield was further modeled using three algorithms (Scaled conjugate gradient, Bayesian regularization and Levenberg maraquardt) of the artificial neural network (ANN). It was evident that the predictions from the Scaled conjugate gradient algorithm were comparable to the experimental responses. Finally, transesterification of raw CFW oil using heterogeneous catalyst from fish bone, was a cost-effective approach for biodiesel production.

Objective Primary care practitioners (PCPs) care for the majority of patients with knee osteoarthritis (KOA). Despite the existing evidence‐based guidelines, PCPs often feel unequipped to evaluate and effectively treat patients with KOA. To address this need, we designed and implemented a free internet‐based program focusing on the diagnosis and treatment of KOA. We assessed whether the program led to improvements in participants’ confidence in their knowledge and skills related to effectively recognizing and caring for patients with or at risk of KOA. Methods We used Caffarella's integrative model to develop a program aligned with the American College of Rheumatology 2019 Guideline for the treatment of KOA. The program incorporated 18 case‐based questions to provide retrieval practice and mastery experiences. We assessed changes in participants’ confidence in their KOA knowledge and skills after program completion. Results Of the first 353 learners completing the program, 53.8% were women, 41.9% had a clinical focus in primary care, and 69.1% were nonphysicians. Overall confidence in KOA knowledge and skills improved after program completion (P

Objective: This study aimed to quantify public acceptability and anticipated uptake with risk stratification incorporated at three points on the bowel cancer screening pathway, compared with current screening in England. Methods: We conducted an online population-based survey of 1,203 UK adults in 2024. The main outcome measures were overall acceptability of three strategies where risk stratification is introduced at 1) the point of eligibility, 2) the referral threshold and 3) the screening interval, compared with the current programme (screening as usual), and the acceptability of high- and low-risk screening practices at each point. Other outcomes included anticipated uptake of screening and the acceptability of data collection methods. Results: Acceptability of risk-stratified eligibility and referral thresholds was significantly greater than for screening as usual (p

Background There is inadequate evidence about the influence of digital and cash payment modalities on the performance of Community Health Workers (CHWs) in underserved communities, such as refugee settlements. Objective To compare the performance of CHWs when paid in cash or digitally in Kyaka II refugee settlement, Uganda. Methods A comparative cross-sectional mixed methods design was used. Secondary data comprising 247 CHW reports during a six-month period of cash and digital payments were analyzed using Stata v14. Eleven focus group discussions, four in-depth interviews, and ten key informant interviews were conducted among the settlement stakeholders to explore perceptions of the payment methods. Qualitative data were analyzed thematically using Atlas.ti v9. Results CHWs performed better when paid cash than digital payments (t = 5.28; df = 246; p

ABSTRACT Context Risk stratification has been suggested as a strategy for improving cancer screening. Any changes to existing programmes must be acceptable to the public. Objective This study aimed to explore the preferences and considerations of individuals relating to the introduction of different risk‐based strategies to determine eligibility for colorectal cancer (CRC) screening. Study Design Participants completed a discrete choice experiment (DCE) within online interviews. Nine conjoint‐analysis tasks were created, each with two potential CRC screening programmes. The attributes included personal risk of CRC, screening invitation strategy and impact. Participants chose between programmes while thinking aloud and sharing their thoughts. Transcripts were analysed using codebook thematic analysis. Participants Twenty participants based in England aged 40–79 years without previous cancer history or medical expertise. Results When choosing between programmes, participants first and primarily looked to prioritise saving lives. The harms associated with screening were viewed as a surprise but also felt by most to be inevitable; the benefits frequently outweighed, therefore, harms were considered less important. Risk stratification using individual characteristics was considered a nuanced approach to healthcare, which tended to be preferred over the age‐alone model. Detailed personal risk information could be taken more seriously than non‐personalised information to motivate behaviour change. Although it had minimal impact on decision‐making, not diverting resources for screening from elsewhere was valued. Individuals who chose not to provide health information were considered irresponsible, while it was important that those with no information to provide should not lose out. Conclusion Risk‐stratified CRC screening is generally aligned with public preferences, with decisions between possible stratification strategies dominated by saving lives. Even if attributes including risk factors, risk stratification strategy and risk communication contributed less to the overall decision to select certain programmes, some levels more clearly fulfilled public values; therefore, all these factors should be taken into consideration when redesigning and communicating CRC screening programmes. Patient or Public Contribution The primary data source for this study is interviews with 20 members of the public (current, past or future CRC screening invitees). Two public representatives contributed to planning this study, particularly the DCE.

Schistosomiasis, one of the neglected tropical diseases which affects both humans and animals, is caused by trematode worms of the genus Schistosoma. The disease is caused by several species of Schistosoma which affect several organs such as urethra, liver, bladder, intestines, skin and bile ducts. The life cycle of the disease involves an intermediate host (snail) and a mammalian host. It affects people who are in close proximity to water bodies where the intermediate host is abundant. Common clinical manifestations of the disease at various stages include fever, chills, headache, cough, dysuria, hyperplasia and hydronephrosis. To date, most of the control strategies are dependent on effective diagnosis, chemotherapy and public health education on the biology of the vectors and parasites. Microscopy (Kato-Katz) is considered the golden standard for the detection of the parasite, while praziquantel is the drug of choice for the mass treatment of the disease since no vaccines have yet been developed. Most of the previous reviews on schistosomiasis have concentrated on epidemiology, life cycle, diagnosis, control and treatment. Thus, a comprehensive review that is in tune with modern developments is needed. Here, we extend this domain to cover historical perspectives, global impact, symptoms and detection, biochemical and molecular characterization, gene therapy, current drugs and vaccine status. We also discuss the prospects of using plants as potential and alternative sources of novel anti-schistosomal agents. Furthermore, we highlight advanced molecular techniques, imaging and artificial intelligence that may be useful in the future detection and treatment of the disease. Overall, the proper detection of schistosomiasis using state-of-the-art tools and techniques, as well as development of vaccines or new anti-schistosomal drugs may aid in the elimination of the disease.

Abstract Single cell and spatially resolved ‘omic’ techniques have enabled deep characterization of clinical pathologies that remain poorly understood, providing unprecedented insights into molecular mechanisms of disease. However, transcriptomic platforms are costly, limiting sample size, which increases the possibility of pre-analytical variables such as tissue processing and storage procedures impacting RNA quality and downstream analyses. Furthermore, spatial transcriptomics have not yet reached single cell resolution, leading to the development of multiple deconvolution methods to predict individual cell types within each transcriptome ‘spot’ on tissue sections. In this study, we performed spatial transcriptomics and single nucleus RNA sequencing (snRNAseq) on matched specimens from patients with either histologically normal or advanced fibrosis to establish important aspects of tissue handling, data processing, and downstream analyses of biobanked liver samples. We observed that tissue preservation technique impacts transcriptomic data, especially in fibrotic liver. Single cell mapping of the spatial transcriptome using paired snRNAseq data generated a spatially resolved, single cell dataset with 24 unique liver cell phenotypes. We determined that cell–cell interactions predicted using ligand–receptor analysis of snRNAseq data poorly correlated with cellular relationships identified using spatial transcriptomics. Our study provides a framework for generating spatially resolved, single cell datasets to study gene expression and cell–cell interactions in biobanked clinical samples with advanced liver disease.

Abstract Background Health insurance has been documented as one of the primary methods of financing healthcare for Sustainable Development Goals (SDGs) by 2030. Yet, there is a dearth of evidence on the determinants of health insurance coverage among women in Mauritania. We examine the factors associated with health insurance coverage among women in Mauritania using a nationally representative survey dataset. Methods We analyzed secondary data from the 2019–2021 Mauritania Demographic and Health Survey. A weighted sample of 15,714 women of reproductive age (15–49 years) was included in the study. Multilevel regression analysis was used to examined the factors associated with health insurance coverage. The results were presented using an adjusted odds ratio (aOR) with a 95% confidence interval (CI). Results The coverage of health insurance among women was 8.7%. The majority of the women subscribed to social security health insurance (7.6%). Women aged 35 years and above [aOR = 1.54; 95% CI = 1.24, 1.92] were more likely to be covered by health insurance relative to those aged 15–24. The likelihood of being covered by health insurance increased with increasing level of education with the highest odds among women with higher education [aOR = 6.09; 95% CI = 3.93, 9.42]. Women in the richest wealth index households [aOR = 22.12; 95% CI = 9.52, 51.41] and those with grand parity [aOR = 2.16; 95% CI = 1.62, 2.87] had the highest odds of being covered by health insurance. Women who were working, those who watched television, and those who used the internet were more likely to be covered by health insurance relative to their counterparts who were not working, those who did not watch television, and those who did not use the internet. Women residing in Tiris zemour et Inchiri [aOR = 3.60; 95%CI = 1.60, 8.10], Tagant (aOR = 3.74; 95% CI = 1.61, 8.68], and Adrar [aOR = 2.76; 95% CI = 1.36, 5.61] regions were more likely to be covered by health insurance compared with those from Hodh Echargui. Conclusion Health insurance coverage among the women in our study was low. Achieving the SDG targets of ensuring universal health coverage and lowering maternal mortality to less than 70 deaths per 100,000 live births requires the implementation of interventions to increase health insurance coverage, taking into consideration the identified factors in the study. We recommend effective public education and awareness creation on the importance of being covered by health insurance by leveraging television and internet platforms. Also, interventions to increase health insurance coverage should consider younger women and those in rural areas.

BackgroundHealth care for women with Female Genital Mutilation/Cutting (FGM/C) in the Global North is often described as sub-optimal and focused on maternity care. Specialist FGM/C services have emerged with little empirical evidence informing service provision. The objective of this scoping review is to identify the key features of FGM/C specialist care.MethodsThe review was conducted in accordance with JBI methodology. Participants: organisations that provide specialist FGM/C care. Concept: components of specialist services. Context: high-income OECD countries. Eligibility criteria included primary research studies of any design from 2012 to 2022, providing a comprehensive description of specialist services. Seven bibliographic databases were searched (MEDLINE, EMBASE, CINAHL, Web of Science, SCOPUS, Cochrane Library and MIC). The components of “specialist” (as opposed to “generalist”) services were defined and then applied to an analysis of FGM/C specialist care. FGM/C specialist provision was categorised into primary (essential) and secondary features. Data were extracted and analysed descriptively through charting in tables and narrative summary.ResultsTwenty-five papers described 20 unique specialist services across eleven high income countries. Primary features used to identify FGM/C specialist care were:—(i) Named as a Specialist service/clinic: 11/20 (55%); (ii) Identified expert lead: 13/20, (65%), either Midwives, Gynaecologists, Urologist, or Plastic Surgeons; (iii) Offering Specialist Interventions: surgical (i.e., reconstruction and/or deinfibulation) and/or psychological (i.e., trauma and/or sexual counselling); and (iv) Providing multidisciplinary care: 14/20 (70%). Eleven services (in Spain, Sweden, Switzerland, Germany, Italy, Netherlands, France, Belgium, and USA) provided reconstruction surgery, often integrated with psychosexual support. No services in UK, Norway, and Australia offered this. Six services (30%) provided trauma therapy only; 25% sexual and trauma therapy; 15% sexual therapy only; 30% did not provide counselling. Secondary features of specialist care were subdivided into (a) context of care and (b) the content of care. The context related to concepts such as provision of interpreters, cost of care, community engagement and whether theoretical underpinnings were described. Content referred to the model of care, whether safeguarding assessments were undertaken, and health education/information is provided.ConclusionOverall, the features and composition of FGM/C specialist services varied considerably between, and sometimes within, countries. Global guidelines advocate that specialist care should include access to deinfibulation, mental health support, sexual counselling, and education and information. The review found that these were rarely all available. In some high-income countries women cannot access reconstruction surgery and notably, few services for non-pregnant women mentioned safeguarding. Furthermore, services for pregnant women rarely integrated trauma therapy or psychosexual support. The review highlights a need for counselling (both trauma and psychosexual) and culturally-appropriate sensitive safeguarding assessments to be embedded into care provision for non-pregnant as well as pregnant women. Further research is needed to extract the features of specialist services into a comprehensive framework which can be used to examine, compare, and evaluate FGM/C clinical specialist care to determine which clinical features deliver the best outcomes. Currently a geographical lottery appears to exist, not only within the UK, but also across the Global North.

Abstract Background Population-based cancer screening programmes are shifting away from age and/or sex-based screening criteria towards a risk-stratified approach. Any such changes must be acceptable to the public and communicated effectively. We aimed to explore the social and ethical considerations of implementing risk stratification at three different stages of the bowel cancer screening programme and to understand public requirements for communication. Methods We conducted two pairs of community juries, addressing risk stratification for screening eligibility or thresholds for referral to colonoscopy and screening interval. Using screening test results (where applicable), and lifestyle and genetic risk scores were suggested as potential stratification strategies. After being informed about the topic through a series of presentations and discussions including screening principles, ethical considerations and how risk stratification could be incorporated, participants deliberated over the research questions. They then reported their final verdicts on the acceptability of risk-stratified screening and what information should be shared about their preferred screening strategy. Transcripts were analysed using codebook thematic analysis. Results Risk stratification of bowel cancer screening was acceptable to the informed public. Using data within the current system (age, sex and screening results) was considered an obvious next step and collecting additional data for lifestyle and/or genetic risk assessment was also preferable to age-based screening. Participants acknowledged benefits to individuals and health services, as well as articulating concerns for people with low cancer risk, potential public misconceptions and additional complexity for the system. The need for clear and effective communication about changes to the screening programme and individual risk feedback was highlighted, including making a distinction between information that should be shared with everyone by default and additional details that are available elsewhere. Conclusions From the perspective of public acceptability, risk stratification using current data could be implemented immediately, ahead of more complex strategies. Collecting additional data for lifestyle and/or genetic risk assessment was also considered acceptable but the practicalities of collecting such data and how the programme would be communicated require careful consideration.

Metabolic alterations are increasingly recognized as important aspects of colorectal cancer (CRC), offering potential avenues for identifying therapeutic targets. Previous studies have demonstrated the cytotoxic potential of bamboo leaf extract obtained from Guadua incana (BLEGI) against HCT-116 colon cancer cells. However, the altered metabolic pathways in these tumor cells remain unknown. Therefore, this study aimed to employ an untargeted metabolomic approach to reveal the metabolic alterations of the endometabolome and exometabolome of HCT-116 cells upon exposure to BLEGI treatment. First, a chemical characterization of the BLEGI was conducted through liquid chromatography coupled with mass spectrometry (LC-MS). Next, we assessed cell viability via MTT and morphological analysis using an immunofluorescence assay against colon cancer cells, and anti-inflammatory activity using an LPS-stimulated macrophage model. Subsequently, we employed LC-MS and proton nuclear magnetic resonance (1H-NMR) to investigate intra- and extracellular changes. Chemical characterization primarily revealed the presence of compounds with a flavone glycoside scaffold. Immunofluorescence analysis showed condensed chromatin and subsequent formation of apoptotic bodies, suggesting cell death by apoptosis. The results of the metabolomic analysis showed 98 differential metabolites, involved in glutathione, tricarboxylic acid cycle, and lipoic acid metabolism, among others. Additionally, BLEGI demonstrated significant nitric oxide (NO) inhibitory capacity in macrophage cells. This study enhances our understanding of BLEGI’s possible mechanism of action and provides fresh insights into therapeutic targets for treating this disease.

Globally, rural conditions are in states of change. They are often highly vulnerable to climate and environmental change, extreme weather events, conflict, socio-economic changes, inequalities, and demographic changes. These changes are putting stress on rural areas, which rely upon agriculture and natural resources for their livelihoods and are often the foundation of national economies. Communication for development (C4D) has played an important role in addressing these challenges. Its thinking is broadly consistent with rural development goals—indeed, the roots of C4D come in part from rural development and agricultural extension. Communication for development (C4D) was defined by the World Congress on Communication for Development as “…a social process based on dialogue using a broad range of tools and methods. It also seeks change at different levels, including listening, building trust, sharing knowledge and skills, building policies, debating, and learning for sustained and meaningful change. It is not public relations or corporate communications”. However, after decades of action to address these interrelated rural development challenges, much remains to be done. This paper critically considers the following: What does inclusive rural development mean now, in light of environmental change, and how does this affect the conceptualisation and practice of C4D? This was done by using three countries as case studies: Malawi, Ukraine, and the Philippines. Each of these countries represented contrasting challenges and opportunities for rural development and environmental change, with lessons from their experiences shedding insight into the communication for development thinking.

Abstract Background Adolescent girls and young women (AGYW) account for 29% of new HIV infections in Uganda despite representing just 10% of the population. Peer support improves AGYW linkage to HIV care and medication adherence. We evaluated the feasibility and acceptability of peer delivered HIV self-tests (HIVST) and oral pre-exposure prophylaxis (PrEP) to young women in Uganda. Methods Between March and September 2021, we conducted a pilot study of 30 randomly selected young women, aged 18–24 years, who had received oral PrEP for at least three months, but had suboptimal adherence as measured by urine tenofovir testing (

Abstract Background Skilled Birth Attendance (SBA) is important in achieving the Sustainable Development Goals (SDGs) targets 3.1, 3.2 and 3.3.1. Ghana has made steady progress in SBA, yet, unsupervised deliveries still occur. The introduction of the Free Maternal Health Care Policy under the National Health Insurance Scheme (FMHCP under the NHIS) has improved the uptake of SBA but with some implementation challenges. This narrative review sought to explore the factors influencing the FMHCP under the NHIS provision for skilled delivery services in Ghana. Methods Electronic searches were conducted of databases including PubMed, Popline, Science direct, BioMed Central, Scopus and Google scholar for peer reviewed articles as well as grey articles from other relevant sources, published between 2003 and 2021 on factors influencing FMHCP/NHIS provision for skilled delivery services in Ghana. Keywords used in the literature search were in various combinations for the different databases. The articles were screened to determine the inclusion and exclusion criteria and quality was assessed using a published critical appraisal checklist. A total of 516 articles were retrieved for initial screening based on their titles, of which 61 of them, were further screened by reading their abstracts and full text. Of this number, 22 peer-reviewed and 4 grey articles were selected for the final review based on their relevance. Results The study revealed that the FMHCP under the NHIS does not cover the full costs associated with skilled delivery and low socioeconomic status of households affects SBA. Also, funding and sustainability, hinders the quality-of-service delivery offered by the policy. Conclusion For Ghana to achieve the SDGs above and further improve SBA, the cost associated with skilled delivery should be fully covered by the NHIS. Also, the government and the key stakeholders involved in the policy implementation, must put in place measures that will enhance the operation and the financial sustainability of the policy.

Abstract Background Intermediate care (IC) services are models of care that aim to bridge the gap between hospital and home, enabling continuity of care and the transition to the community. The purpose of this study was to explore patient experience with a step-down, intermediate care unit in Buckinghamshire, UK. Methods A mixed-methods study design was used. Twenty-eight responses to a patient feedback questionnaire were analysed and seven qualitative semi-structured interviews were conducted. The eligible participants were patients who had been admitted to the step-down IC unit. Interview transcripts were analysed using thematic analysis. Findings Our interview data generated five core themes: (1) “Being uninformed”, (2) “Caring relationships with health practitioners”, (3) “Experiencing good intermediate care”, (4) “Rehabilitation” and (5) “Discussing the care plan”. When comparing the quantitative to the qualitative data, these themes are consistent. Conclusions Overall, the patients reported that the admission to the step-down care facility was positive. Patients highlighted the supportive relationship they formed with healthcare professionals in the IC and that the rehabilitation that was offered in the IC service was important in increasing mobility and regaining their independence. In addition, patients reported that they were largely unaware about their transfer to the IC unit before this occurred and they were also unaware of their discharge package of care. These findings will inform the evolving patient-centred journey for service development within intermediate care.

Abstract Introduction Risk‐stratified cancer screening has the potential to improve resource allocation and the balance of harms and benefits by targeting those most likely to benefit. Public acceptability has implications for engagement, uptake and the success of such a programme. Therefore, this review seeks to understand whether risk stratification of population‐based cancer screening programmes is acceptable to the general public and in what context. Methods Four electronic databases were searched from January 2010 to November 2021. Qualitative, quantitative and mixed‐methods papers were eligible for inclusion. The Joanna Briggs Institute convergent integrated approach was used to synthesize the findings and the quality of included literature was assessed using the Mixed Methods Appraisal Tool. The Theoretical Framework of Acceptability was used as a coding frame for thematic analysis. PROSPERO record 2021 CRD42021286667. Results The search returned 12,039 citations, 22 of which were eligible for inclusion. The majority of studies related to breast cancer screening; other cancer types included ovarian, kidney, colorectal and prostate cancer. Risk stratification was generally acceptable to the public, who considered it to be logical and of wider benefit than existing screening practices. We identified 10 priorities for implementation across four key areas: addressing public information needs; understanding communication preferences for risk estimates; mitigating barriers to accessibility to avoid exacerbating inequalities; and the role of healthcare professionals in relation to supporting reduced screening for low‐risk individuals. Conclusion The public generally find risk stratification of population‐based cancer screening programmes to be acceptable; however, we have identified areas that would improve implementation and require further consideration. Patient or Public Contribution This paper is a systematic review and did not formally involve patients or the public; however, three patient and public involvement members were consulted on the topic and scope before the review commenced.

The leucine-rich repeat-containing protein 25 (LRRC25) is relatively a novel protein with no information on its role in neuronal or brain function. A recent study suggested LRRC25 is a potential risk factor for Alzheimer’s disease (AD). As a first step to understanding LRRC25’s role in the brain and AD, we found LRRC25 is expressed in both cell membranes and cytoplasm in a punctuate appearance in astrocytes, microglia, and neurons in cell lines as well as mouse brain. We also found that LRRC25 expression is both age- and brain region-dependent and that 1-day-old (1D) pups expressed the least amount of LRRC25 protein compared to adult ages. In the APΔE9 mice, immunoblot quantified LRRC25 protein levels were increased by 166% (**p < 0.01) in the cortex (CX) and by 215% (***p < 0.001) in the hippocampus (HP) relative to wild-type (WT) controls. Both the brainstem (BS) and cerebellum (CB) showed no significant alterations. In the 3xTg mice, only CX showed an increase of LRRC25 protein by 91% (*p < 0.05) when compared to WT controls although the increased trend was noted in the other brain regions. In the AD patient brains also LRRC25 protein levels were increased by 153% (***p < 0.001) when compared to normal control (NC) subjects. Finally, LRRC25 expression in the iPSC-derived neurons quantified by immunofluorescence was increased by 181% (**p < 0.01) in AD-derived neurons when compared to NC-derived neurons. Thus increased LRRC25 protein in multiple models of AD suggests that LRRC25 may play a pathogenic role in either Aβ or tau pathology in AD. The mechanism for the increased levels of LRRC25 in AD is unknown at present, but a previous study showed that LRRC25 levels also increase during neonatal hypoxic-ischemia neuronal damage. Based on the evidence that autophagy is highly dysregulated in AD, the increased LRRC25 levels may be due to decreased autophagic degradation of LRRC25. Increased LRRC25 in turn may regulate the stability or activity of key enzymes involved in either Aβ or hyperphosphorylated tau generation and thus may contribute to increased plaques and neurofibrillary tangles.

BackgroundWhereas digital payments have been identified as a solution to health payment challenges, evidence on their adoptability among Community Health Workers (CHWs) is limited. Understanding their adoptability is crucial for sustainability. This study assessed the adoptability of digital payments for CHWs in Wakiso district, Uganda.MethodsA convergent parallel mixed-methods study was conducted between November and December 2022, in Wakiso district, Uganda. We surveyed a random sample of 150 CHWs using a structured questionnaire and conducted key informant interviews among three purposively selected Digital payment coordinators. The study utilized the Technology Acceptance Model (TAM) framework to assess the adoptability of digital payments among CHWs. Factor analysis was performed to extract composite variables from the original constituting variables. Using the median, the outcome was converted to a binary variable and logistic regression was conducted to assess the association between the TAM constructs and adoptability of digital payments by CHWs. Quantitative data was analyzed using STATA 14, while qualitative data was transcribed verbatim and analyzed using ATLAS.ti 22.ResultsNearly all participants (98.0%; n = 49) had previously received payments through mobile money, a digital payment method. (52%; n = 78) of CHWs said they intend to use digital payment modalities. Perceived risk of digital payments was associated with 83% lower odds of adoptability of digital payment modalities (OR = 0.17;95%CI:0.052, 0.54), while perceived trust had nearly three times higher odds of adoptability of digital payment modalities (OR = 2.82;95%CI:1.41, 5.67). Qualitative interviews showed that most CHWs reported positive experiences with digital health payments, including effectiveness and completeness of payments except for delays associated with mobile money payments across payment providers. Mobile money was reported to be easy to use, in addition to fostering financial responsibility compared to cash.ConclusionCHWs in Wakiso district intend to use digital payment modalities, particularly mobile money/e-cash. Perceived risk of the payment method and trust are key determinants of adoptability. Synergized efforts by both payment providers to manage payment delays and mitigate risks associated with digital payments could attenuate perceived risk and build trust in digital payment modalities.

BackgroundIn 2019, WHO recommended dolutegravir (DTG) as a backbone for first- and second-line antiretroviral therapy (ART) regimens for people living with HIV (PLHIV). According to the 2018 Uganda's HIV treatment guidelines, patients with viral non-suppression (≥1,000 copies/mL) should receive intensive adherence counseling (IAC) with repeat viral load (VL) within 6 months. This analysis focused on the prevalence and factors associated with viral suppression following IAC among PLHIV on DTG-based regimens (DBRs) with an initial episode of viral non-suppression (VNS) in Uganda.MethodsWe conducted a retrospective analysis for PLHIV on DBRs with an initial episode of VNS (≥1,000 copies/mL) in Uganda during October 2019-September 2020 who had a follow up VL test result during September 2020-July 2021. Data were abstracted from the Central Public Health Laboratory (CPHL) database, including patient demographics and VL results. Viral non-suppression (VNS) was defined as a VL test result of ≥1,000 copies/mL. We characterized PLHIV on DBRs and used logistic regression models to determine factors associated with VL suppression after an initial episode of VNS.ResultsA total of 564 PLHIV on DBRs with an initial episode of VNS were followed up and 43 were excluded due to missing data. Of the 521, 220 (42.2%) were children (ConclusionsIn a programmatic setting, most adults and children suppressed following an initial episode of VNS on DBRs. High rates of suppression after VNS suggest adherence challenges, rather than drug resistance. Continuation of DBRs should be considered before regimen switch.

Introduction Breast cancer incidence starts to increase exponentially when women reach 30–39 years, hence before they are eligible for breast cancer screening. The introduction of breast cancer risk assessment for this age group could lead to those at higher risk receiving benefits of earlier screening and preventive strategies. Currently, risk assessment is limited to women with a family history of breast cancer only. The Breast CANcer Risk Assessment in Younger women (BCAN-RAY) study is evaluating a comprehensive breast cancer risk assessment strategy for women aged 30–39 years incorporating a questionnaire of breast cancer risk factors, low-dose mammography to assess breast density and polygenic risk. This study will assess the feasibility and acceptability of the BCAN-RAY risk assessment strategy.Methods and analysis This study involves women undergoing risk assessment as part of the BCAN-RAY case-control study (n=750). They will be aged 30–39 years without a strong family history of breast cancer and invited to participate via general practice. A comparison of uptake rates by socioeconomic status and ethnicity between women who participated in the BCAN-RAY study and women who declined participation will be conducted. All participants will be asked to complete self-report questionnaires to assess key potential harms including increased state anxiety (State Trait Anxiety Inventory), cancer worry (Lerman Cancer Worry Scale) and satisfaction with the decision to participate (Decision Regret Scale), alongside potential benefits such as feeling more informed about breast cancer risk. A subsample of approximately 24 women (12 at average risk and 12 at increased risk) will additionally participate in semistructured interviews to understand the acceptability of the risk assessment strategy and identify any changes needed to it to increase uptake.Ethics and dissemination Ethical approval was granted by North West—Greater Manchester West Research Ethics Committee (reference: 22/NW/0268). Study results will be disseminated through peer-reviewed journals, conference presentations and charitable organisations.Trial registration number NCT05305963.

The achievement of the Sustainable Development Goals (SDGs) targets 3.1, 3.2 and 3.3.1 is strongly dependent on the effective utilization of skilled birth services. Despite advancements made in Skilled Birth Attendance (SBA) in Ghana, there are still instances of unassisted childbirths taking place. The aim of this study was to explore the residual barriers of SBA such as community- and health system-related factors affecting SBA in Ghana and to identify strategies for addressing them. An electronic search was done using PubMed, Popline, Science direct, BioMed Central, Scopus and Google scholar for peer reviewed articles as well as grey articles from other relevant sources, published between 200 and 2022 on community- and health system related factors influencing SBA in Ghana. Out of the 89 articles retrieved for full screening, a total of 52 peer-reviewed articles and 1 grey article were selected for the final review. The study revealed that cultural practices (community factors), low quality of service delivery due to the inappropriate behaviors, lack of competency of skilled birth attendants (SBAs) as well as the inefficient distribution of SBAs contribute to ineffective uptake of SBA (health system factors). Also, indirect costs are associated with the utilization of skilled delivery care even with the existence of 'free' delivery care policy under the national health insurance (policy factor). For Ghana to achieve the SDGs above and improve SBA, it is essential to enhance the quality of skilled delivery care by addressing the attitude and competencies of skilled birth professionals, while plans are put in place to expand and develop the Community-based Health Planning and Services (CHPS) strategy to help address the access barriers to SBA. More so, the 'free' delivery care policy should absorb all the costs associated with skilled delivery for pregnant women as it is intended for.

Aflatoxin contamination in peanuts (Arachis hypogaea L.) by aflatoxin-producing Aspergillus spp. is a serious problem worldwide affecting human health and restricting trade. Recently, conservation agriculture practices such as minimum tillage, crop rotation, soil surface cover, intercropping, and planting in basins alongside trees that enhance soil fertility, have been introduced in Zambia as tools to conserve soil moisture, increase peanut yield, and reduce the risk of aflatoxin contamination. However, a limited understanding exists of the impact of conservation agriculture on Aspergillus population densities in the soil and aflatoxin concentrations in crops grown under conservation agriculture. This study assessed the impact of conservation agriculture on (i) Aspergillus communities profile in soil cropped to peanuts, (ii) peanut aflatoxin contamination levels, and (iii) influences of the practices on liver cancer risks as a result of consuming peanuts grown in basins, peanuts grown in basins in farms having Gliricidia sepium trees (agroforestry), and peanuts grown on ridges (conventional tillage). Densities of Aspergillus spp. in soils ranged from 10 to 7,400 CFU/g (mean = 295 CFU/g). The densities differed among farming techniques (p = 0.0011) with conventional tillage (357 CFU/g) supporting higher densities than agroforestry (296 CFU/g) and peanuts grown in basins (230 CFU/g). Aspergillus communities were dominated by fungi with S morphology (55%; which is composed of several morphologically similar species), followed by A. parasiticus (34%), and the L morphotype of A. flavus (11%). Over 60% of the peanut samples were contaminated but there were no differences among farming techniques. Mean aflatoxin contents in peanuts were 110, 99, and 87, μg/kg for agroforestry, conventional tillage, and peanuts grown in basins, respectively. Probable daily aflatoxin intake ranged from 12.7 to 767.1 ng/kg body weight/d, depending on the age of consumers. The estimated liver cancer risk due to consumption of raw peanuts (0.334 to 20.128 cases/100,000 persons/year) was highest among children below 5 years and least for young adults. The results showed that growing peanuts in basins has the potential to reduce Aspergillus populations in soil. Possibly, planting in basins and agroforestry had minimal effect on water runoff and did not support sufficient moisture retention in the soil to reduce Aspergillus spp. densities and aflatoxin accumulation in the peanuts. Thus, more research is needed to improve the effectiveness of peanut cultivation in basins in shaping the Aspergillus species profiles for ultimately reducing aflatoxin in peanuts to safe levels. Given the high exposure of Zambia’s population, especially children, and that contaminated food is the major source of exposure, it is essential that appropriate technical, policy and institutional measures are promoted for aflatoxin mitigation in Zambia.

This study features comprehensive physical and electrochemical properties of different polyolefin and non-polyolefin separators. These separators include polypropylene-polyethylene-polypropylene (PEP), polyethylene (PE), Al2O3-coated polypropylene (C-PP), polyethylene terephthalate (PET), and Silicon carbide mat (SiCmat). The interaction of the different separators and the electrolyte was investigated in terms of ionic conductivity, contact angle test, electrolyte uptake, and electrolyte oxidation. The full cells fabricated using the different separators were also studied for charge–discharge performance, cycle performance, and internal resistance. Results showed that the different separators demonstrated different physical and electrochemical behavior. The non-polyolefin separators registered a small electrolyte contact angle due to their high porosity and structural compatibility with the electrolyte. At 10 C-Rate, the specific capacity is in the order of PET > SiCmat > C-PP > PE > PEP corresponding to 90 mAh/g, 85 mAh/g, 70 mAh/g, 60 mAh/g and 40 mAh/g respectively. After 100 cycles at 1.0 C-rate, the cycle performance is in the order of PE > PET > C-PP > SiCmat > PEP corresponding to 70 %, 65 %, 61 %, 51 % and 49 % respectively. Thermally, PET, C-PP and SiCmat showed better thermal stability compared to the other separators. Therefore, Industrial production that requires high thermal stability may rely on C-PP, PET, or SiCmat, while PET and SiCmat offer better cycle performance and may replace commercially available PE and PEP.

ABSTRACTBackground Most medical students entering clerkships have limited understanding of clinical reasoning concepts. The value of teaching theories of clinical reasoning and cognitive biases to first-year medical students is unknown. This study aimed to evaluate the value of explicitly teaching clinical reasoning theory and cognitive bias to first-year medical students.Methods Using Kolb’s experiential learning model, we introduced dual process theory, script theory, and cognitive biases in teaching clinical reasoning to first-year medical students at an academic medical center in New York City between January and June 2020. Due to the COVID-19 pandemic, instruction was transitioned to a distance learning format in March 2020. The curriculum included a series of written clinical reasoning examinations with facilitated small group discussions. Written self-assessments prompted each student to reflect on the experience, draw conclusions about their clinical reasoning, and plan for future encounters involving clinical reasoning. We evaluated the value of the curriculum using mixed-methods to analyze faculty assessments, student self-assessment questionnaires, and an end-of-curriculum anonymous questionnaire eliciting student feedback.Results Among 318 total examinations of 106 students, 254 (80%) had a complete problem representation, while 199 (63%) of problem representations were considered concise. The most common cognitive biases described by students in their clinical reasoning were anchoring bias, availability bias, and premature closure. Four major themes emerged as valuable outcomes of the CREs as identified by students: (1) synthesis of medical knowledge; (2) enhanced ability to generate differential diagnoses; (3) development of self-efficacy related to clinical reasoning; (4) raised awareness of personal cognitive biases.Conclusions We found that explicitly teaching clinical reasoning theory and cognitive biases using an experiential learning model provides first-year medical students with valuable opportunities for developing knowledge, skills, and self-efficacy related to clinical reasoning.

Abstract Background Despite efforts from the government and developmental partners to eliminate gender-based violence, intimate partner violence (IPV) remains a pervasive global health and human rights problem, affecting up to 753 million women and girls globally. Few studies on IPV have focused on pregnant and parenting adolescent (PPA) girls in Africa, although the region has the highest rates of adolescent childbearing. This limited attention results in the neglect of pregnant and parenting adolescents in policies and interventions addressing IPV in the region. Our study examined IPV prevalence and its individual, household, and community-level correlates among pregnant and parenting adolescent girls (10–19 years) in Blantyre District, Malawi. Methods We collected data from a cross-section of pregnant and parenting adolescent girls (n = 669) between March and May 2021. The girls responded to questions on socio-demographic and household characteristics, lifetime experience of IPV (i.e., sexual, physical, and emotional violence), and community-level safety nets. We used multilevel mixed-effect logistic regression models to examine the individual, household, and community-level factors associated with IPV. Results The lifetime prevalence of IPV was 39.7% (n = 266), with more girls reporting emotional (28.8%) than physical (22.2%) and sexual (17.4%) violence. At the individual level, girls with secondary education (AOR: 1.72; 95% CI: 1.16–2.54), who engaged in transactional sex (AOR: 2.29; 95% CI: 1.35–3.89), and accepted wife-beating (AOR: 1.97; 95% CI: 1.27–3.08) were significantly more likely to experience IPV compared to those with no education/primary education, who never engaged in transactional sex and rejected wife beating. Girls aged 19 (AOR: 0.49; 95% CI: 0.27–0.87) were less likely to report IPV than those aged 13–16. At the household level, girls with fair and poor partner support had higher odds of experiencing IPV, but the effect size did not reach a significant level in the parsimonious model. A high perception of neighborhood safety was associated with a lower likelihood of experiencing IPV (AOR: 0.81; 95% CI: 0.69–0.95). Conclusion Intimate partner violence is rife among pregnant and parenting adolescent girls in Malawi, underscoring the need for appropriate interventions to curb the scourge. Interventions addressing IPV need to target younger adolescents, those engaging in transactional sex, and those having weaker community-level safety nets. Interventions to change social norms that drive the acceptance of gender-based violence are also warranted.

Prior faecal Hemoglobin (f-Hb) concentrations of a negative fecal immunochemical test (FIT) can be used for risk stratification in colorectal cancer (CRC) screening. Individuals with higher f-Hb concentrations may benefit from a shorter screening interval (1 year), whereas individuals with undetectable f-Hb concentrations could benefit from a longer screening interval (3 year). Individuals’ views on personalised CRC screening and information needed to make a well-informed decision is unknown. We conducted three semi-structured focus groups among individuals eligible for CRC screening (i.e. men and women aged 55 to 75) in the Netherlands. Thematic analysis was used to analyse participants’ information need on personalised CRC screening strategies. Fourteen individuals took part. The majority were positive about CRC screening and indicated that they would participate in personalised CRC screening. The rationale for a longer interval among those at lowest risk was, however, unclear for many. The preferred information on individual risk was variable: ranging from full information to only information on the personalised strategy without mentioning the risk. It was not possible to address everyone’s need with a single approach. Additional communications, e.g. public media campaigns, billboards, videos on social media, were also suggested as necessary. This study showed that preferences on receiving information on individual CRC risk varied substantially and no consensus was reached. Introducing a personalised screening programme will require careful communication, particularly around the rationale for the strategy, and a layered approach to deliver information.

Formation of lysinoalanine protein–protein crosslinks during food processing adversely impacts nutritional value. However, mapping lysinoalanine directly in food is challenging. We characterized the fragmentation pattern of lysinoalanine crosslinks in synthetic peptide models over a range of pH and time treatments using mass spectrometry. A putative diagnostic ion resulting from the cleavage of the α-carbon and β-carbon of lysinoalanine is identified in MALDI MS/MS spectra. This represents the first step in mapping lysinoalanine in real food samples with higher precision than currently identifiable through standard or customized software. We then determined a correlated trend in the reduction of disulfide bonds and formation of lysinoalanine with increasing pH and time. Mapping lysinoalanine formation is critical to enhance our understanding of molecular processes impacting the nutritional value of foods, including notably in the development of protein alternatives that use alkaline treatment to extract protein isolates.

Summary: Ferroptosis is a form of regulated cell death with roles in degenerative diseases and cancer. Excessive iron-catalyzed peroxidation of membrane phospholipids, especially those containing the polyunsaturated fatty acid arachidonic acid (AA), is central in driving ferroptosis. Here, we reveal that an understudied Golgi-resident scaffold protein, MMD, promotes susceptibility to ferroptosis in ovarian and renal carcinoma cells in an ACSL4- and MBOAT7-dependent manner. Mechanistically, MMD physically interacts with both ACSL4 and MBOAT7, two enzymes that catalyze sequential steps to incorporate AA in phosphatidylinositol (PI) lipids. Thus, MMD increases the flux of AA into PI, resulting in heightened cellular levels of AA-PI and other AA-containing phospholipid species. This molecular mechanism points to a pro-ferroptotic role for MBOAT7 and AA-PI, with potential therapeutic implications, and reveals that MMD is an important regulator of cellular lipid metabolism.

Objective Self‐efficacy, the internal belief that one can perform a specific task successfully, influences behavior. To promote critical appraisal of medical literature, rheumatology training programs should foster both competence and self‐efficacy for critical appraisal. This study aimed to investigate whether select items from the Clinical Research Appraisal Inventory (CRAI), an instrument measuring clinical research self‐efficacy, could be used to measure critical appraisal self‐efficacy (CASE). Methods One hundred twenty‐five trainees from 33 rheumatology programs were sent a questionnaire that included two sections of the CRAI. Six CRAI items relevant to CASE were identified a priori; responses generated a CASE score (total score range 0‐10; higher = greater confidence in one's ability to perform a specific task successfully). CASE scores' internal structure and relation to domain‐concordant variables were analyzed. Results Questionnaires were completed by 112 of 125 (89.6%) trainees. CASE scores ranged from 0.5 to 8.2. The six CRAI items contributing to the CASE score demonstrated high internal consistency (Cronbach's α = 0.95) and unidimensionality. Criterion validity was supported by the findings that participants with higher CASE scores rated their epidemiology and biostatistics understanding higher than that of peers (P

The incidence of renal cell carcinoma (RCC) has risen worldwide over the past few decades, and this has been associated with a stage shift. Survival outcomes of RCC depend largely on the stage at diagnosis. Although overall mortality has stabilized or declined in most countries, survival remains poor in late-stage disease, suggesting early detection may improve overall survival outcomes. A number of potential candidate screening tools have been considered (including urinary dipstick, blood- and urine-based biomarkers, ultrasound, and computed tomography [CT]), though it may be that a combination of these approaches may be optimal. Ultimately, the sensitivity and specificity of the chosen screening tool will determine the rate of false positives and false negatives, which must be minimized. One of the key challenges is the relatively low prevalence of the disease, which might be overcome by performing risk-stratified screening or screening for more than one condition (such as combined lung and kidney cancer screening). Both approaches have been shown to be acceptable to the general public, and they may maximize the efficiency of screening while reducing harms. Indeed, quantifying benefits and harms of screening is key (including the impact on overdiagnosis and quality of life). Whether screening for RCC will lead to a stage shift and the impact on survival are the decisive missing pieces of information that will determine whether the screening program might be adopted into clinical practice (along with feasibility, acceptability, and cost-effectiveness).

Beginning in March 2020, to reduce COVID-19 transmission, the US President’s Emergency Plan for AIDS Relief supporting voluntary medical male circumcision (VMMC) services was delayed in 15 sub-Saharan African countries. We reviewed performance indicators to compare the number of VMMCs performed in 2020 with those performed in previous years. In all countries, the annual number of VMMCs performed decreased 32.5% (from 3,898,960 in 2019 to 2,631,951 in 2020). That reduction is largely attributed to national and local COVID-19 mitigation measures instituted by ministries of health. Overall, 66.7% of the VMMC global annual target was met in 2020, compared with 102.0% in 2019. Countries were not uniformly affected; South Africa achieved only 30.7% of its annual target in 2020, but Rwanda achieved 123.0%. Continued disruption to the VMMC program may lead to reduced circumcision coverage and potentially increased HIV-susceptible populations. Strategies for modifying VMMC services provide lessons for adapting healthcare systems during a global pandemic.

Abstract Background Although tuberculosis (TB) is a curable disease, treatment is complex and prolonged, requiring considerable commitment from patients. This study aimed to understand the common perspectives of TB patients across Brazil, Russia, India, China, and South Africa throughout their disease journey, including the emotional, psychological, and practical challenges that patients and their families face. Methods This qualitative market research study was conducted between July 2020 and February 2021. Eight TB patients from each country (n = 40) completed health questionnaires, video/telephone interviews, and diaries regarding their experiences of TB. Additionally, 52 household members were interviewed. Patients at different stages of their TB treatment journey, from a range of socioeconomic groups, with or without TB risk factors were sought. Anonymized data underwent triangulation and thematic analysis by iterative coding of statements. Results The sample included 23 men and 17 women aged 13–60 years old, with risk factors for TB reported by 23/40 patients. Although patients were from different countries and cultural backgrounds, experiencing diverse health system contexts, five themes emerged as common across the sample. 1) Economic hardship from loss of income and medical/travel expenses. 2) Widespread stigma, delaying presentation and deeply affecting patients’ emotional wellbeing. 3) TB and HIV co-infection was particularly challenging, but increased TB awareness and accelerated diagnosis. 4) Disruption to family life strained relationships and increased patients’ feelings of isolation and loneliness. 5) The COVID-19 pandemic made it easier for TB patients to keep their condition private, but disrupted access to services. Conclusions Despite disparate cultural, socio-economic, and systemic contexts across countries, TB patients experience common challenges. A robust examination of the needs of individual patients and their families is required to improve the patient experience, encourage adherence, and promote cure, given the limitations of current treatment.

Background: Metabolic conditions, including intermediate hyperglycemia (IH), affect migrants to a greater extent than the populations of origin. Evidence suggests that IH increases the risk of vascular complications, but it is unclear whether the differences in IH between the non-migrant and migrant populations translate to differences in vascular complications between the two populations. We compared the prevalence of macrovascular and renal microvascular complications among West Africans with IH living in West Africa and their migrant compatriots in Europe. Methods: Data from the multicenter Research on Obesity and Diabetes among African Migrants(RODAM) study were analyzed. Ghanaians with IH(524 non-migrant and 1439 migrants) were included. Logistic regression analyses were used to determine the associations between migrant status and macrovascular [coronary artery disease(CAD) and peripheral artery disease(PAD)] and renal microvascular[nephropathy] complications with adjustment for age, sex, socioeconomic status, smoking, systolic blood pressure, BMI, total cholesterol, HbA1c, C-reactive protein, and serum uric acid. Findings: The prevalence of microvascular/macrovascular complications was higher in non-migrants than in migrants(nephropathy 15.3vs.9.7%; PAD 3.1%vs.1.3%; and CAD 15.8% vs. 5.0%). The differences persisted in the fully adjusted model: nephropathy [odds ratio, 2.12; 95% CI(1.46–3.08); PAD, 4.44(1.87–10.51); CAD 2.35(1.64–3.37)]. Non-migrant females had higher odds of nephropathy[2.14(1.34–3.43)], PAD[7.47(2.38–23.40)] and CAD [2.10(1.34–3.27)] compared to migrant females. Non-migrant males had higher odds of nephropathy[2.54(1.30–4.97)] and CAD[2.85(1.48–5.50)], but not PAD[1.81(0.32–10.29)],than their migrant peers. Interpretation: Macrovascular and renal microvascular complications were more prevalent in non-migrants than in migrant West Africans with IH. Further studies are needed to identify factors that increase the risk to aid preventive/treatment strategies.

Background The aim of this study was to provide quantitative evidence of the use of polygenic risk scores for systematically identifying individuals for invitation for full formal cardiovascular disease (CVD) risk assessment. Methods and Results A total of 108 685 participants aged 40 to 69 years, with measured biomarkers, linked primary care records, and genetic data in UK Biobank were used for model derivation and population health modeling. Prioritization tools using age, polygenic risk scores for coronary artery disease and stroke, and conventional risk factors for CVD available within longitudinal primary care records were derived using sex‐specific Cox models. We modeled the implications of initiating guideline‐recommended statin therapy after prioritizing individuals for invitation to a formal CVD risk assessment. If primary care records were used to prioritize individuals for formal risk assessment using age‐ and sex‐specific thresholds corresponding to 5% false‐negative rates, then the numbers of men and women needed to be screened to prevent 1 CVD event are 149 and 280, respectively. In contrast, adding polygenic risk scores to both prioritization and formal assessments, and selecting thresholds to capture the same number of events, resulted in a number needed to screen of 116 for men and 180 for women. Conclusions Using both polygenic risk scores and primary care records to prioritize individuals at highest risk of a CVD event for a formal CVD risk assessment can efficiently prioritize those who need interventions the most than using primary care records alone. This could lead to better allocation of resources by reducing the number of risk assessments in primary care while still preventing the same number of CVD events.

Aflatoxin contamination along the processing points of locally made complementary food composite needs to be ascertained and minimized to reduce exposure to weaning children. The study established the concentrations of total aflatoxin (TAF) and aflatoxin B1 (AFB1) along the processing points of locally made malted millet sesame soybean composite (MMSSC) across season one (wet) and season two (dry) and determined children's exposure to them. A total of 363 samples were collected in 2019. TAF and AFB1 concentrations were determined quantitatively using an enzyme-linked immunosorbent assay (ELISA). Consequently, exposure of individual children was assessed as Estimated Daily Intake (EDI), (ng kg−1 bw day−1). All the samples along the processing points had detectable concentrations of TAF and AFB1 ranging from 0.578 μg kg−1 to 1.187 μg kg−1 and 0.221 μg kg−1 to 0.649 μg kg−1 respectively. Contamination was highest in raw materials; soybean (Glycine max) > sesame (Sesamum indicum), followed by stored composite, freshly prepared composite, and least in millet (Eleusine coracana). Contamination varied significantly across seasons with the wet season having higher contamination than the dry season at P = 0.05. All samples (100%) were within the European Commission (EC) acceptable maximum tolerable level for TAF and AFB1 (4 μg kg−1 and 2 μg kg−1) respectively for processed foods for general consumption. But were below the EU acceptable maximum tolerable level for TAF and AFB1 (0.4 μg kg−1 and 0.1 μg kg−1) respectively for processed baby foods cereals. However, all were within the United States- Food and Drug Authority (US-FDA) and East African Community (EAC) set maximum acceptable limit of 20 μg kg−1 for TAFs, 10 μg kg−1 and 5 μg kg−1 for TAF and AFB1 respectively. Conversely, exposure to these toxins was much higher than the Provisional Maximum Tolerable Dietary Intake (PMTDI) of 0.4 ng kg−1 bw day−1 to 1.0 ng kg−1 bw day−1. A significant difference in exposure to both toxins was observed with the weight. The age of 5 months was the most exposed. A concerted effort is needed to reduce children's exposure to MMSSC to TAF and AFB1, taking sesame and soybean as priority ingredients and proper storage based on season to control contamination.

In overcoming the worldwide problem of overweight and obesity, automatic dietary monitoring (ADM) is introduced as support in dieting practises. ADM aims to automatically, continuously, and objectively measure dimensions of food intake in a free-living environment. This could simplify the food registration process, thereby overcoming frequent memory, underestimation, and overestimation problems. In this study, an eating event detection sensor system was developed comprising a smartwatch worn on the wrist containing an accelerometer and gyroscope for eating gesture detection, a piezoelectric sensor worn on the jaw for chewing detection, and a respiratory inductance plethysmographic sensor consisting of two belts worn around the chest and abdomen for food swallowing detection. These sensors were combined to determine to what extent a combination of sensors focusing on different steps of the dietary cycle can improve eating event classification results. Six subjects participated in an experiment in a controlled setting consisting of both eating and non-eating events. Features were computed for each sensing measure to train a support vector machine model. This resulted in F1-scores of 0.82 for eating gestures, 0.94 for chewing food, and 0.58 for swallowing food.

Abstract Introduction Using risk stratification to determine eligibility for cancer screening is likely to improve the efficiency of screening programmes by targeting resources towards those most likely to benefit. We aimed to explore the implications of this approach from a societal perspective by understanding public views on the most acceptable stratification strategies. Methods We conducted three online community juries with 9 or 10 participants in each. Participants were purposefully sampled by age (40–79 years), sex, ethnicity, social grade and English region. On the first day, participants were informed of the potential benefits and harms of cancer screening and the implications of different ways of introducing stratification using scenarios based on phenotypic and genetic risk scores. On the second day, participants deliberated to reach a verdict on the research question, ‘Which approach(es) to inviting people to screening are acceptable, and under what circumstances?’ Deliberations and feedback were recorded and analysed using thematic analysis. Results Across the juries, the principle of risk stratification was generally considered to be an acceptable approach for determining eligibility for screening. Disregarding increasing capacity, the participants considered it to enable efficient resource allocation to high‐risk individuals and could see how it might help to save lives. However, there were concerns regarding fair implementation, particularly how the risk assessment would be performed at scale and how people at low risk would be managed. Some favoured using the most accurate risk prediction model whereas others thought that certain risk factors should be prioritized (particularly factors considered as non‐modifiable and relatively stable, such as genetics and family history). Transparently justifying the programme and public education about cancer risk emerged as important contributors to acceptability. Conclusion Using risk stratification to determine eligibility for cancer screening was acceptable to informed members of the public, particularly if it included risk factors they considered fair and when communicated transparently. Patient or Public Contribution Two patient and public involvement representatives were involved throughout this study. They were not involved in synthesizing the results but contributed to producing study materials, co‐facilitated the community juries and commented on the interpretation of the findings and final report.

Abstract Background Buruli ulcer (BU) is a neglected tropical disease caused by Mycobacterium ulcerans that affects skin, soft tissues, and bones, causing long-term morbidity, stigma, and disability. The recommended treatment for BU requires 8 weeks of daily rifampicin and clarithromycin together with wound care, physiotherapy, and sometimes tissue grafting and surgery. Recovery can take up to 1 year, and it may pose an unbearable financial burden to the household. Recent in vitro studies demonstrated that beta-lactams combined with rifampicin and clarithromycin are synergistic against M. ulcerans. Consequently, inclusion of amoxicillin/clavulanate in a triple oral therapy may potentially improve and shorten the healing process. The BLMs4BU trial aims to assess whether co-administration of amoxicillin/clavulanate with rifampicin and clarithromycin could reduce BU treatment from 8 to 4 weeks. Methods We propose a randomized, controlled, open-label, parallel-group, non-inferiority phase II, multi-centre trial in Benin with participants stratified according to BU category lesions and randomized to two oral regimens: (i) Standard: rifampicin plus clarithromycin therapy for 8 weeks; and (ii) Investigational: standard plus amoxicillin/clavulanate for 4 weeks. The primary efficacy outcome will be lesion healing without recurrence and without excision surgery 12 months after start of treatment (i.e. cure rate). Seventy clinically diagnosed BU patients will be recruited per arm. Patients will be followed up over 12 months and managed according to standard clinical care procedures. Decision for excision surgery will be delayed to 14 weeks after start of treatment. Two sub-studies will also be performed: a pharmacokinetic and a microbiology study. Discussion If successful, this study will create a new paradigm for BU treatment, which could inform World Health Organization policy and practice. A shortened, highly effective, all-oral regimen will improve care of BU patients and will lead to a decrease in hospitalization-related expenses and indirect and social costs and improve treatment adherence. This trial may also provide information on treatment shortening strategies for other mycobacterial infections (tuberculosis, leprosy, or non-tuberculous mycobacteria infections).

Bamboo species have traditionally been used as building material and potential source of bioactive substances, as they produce a wide variety of phenolic compounds, including flavonoids and cinnamic acid derivatives that are considered biologically active. However, the effects of growth conditions such as location, altitude, climate, and soil on the metabolome of these species still need to be fully understood. This study aimed to evaluate variations in chemical composition induced by altitudinal gradient (0–3000 m) by utilizing an untargeted metabolomics approach and mapping chemical space using molecular networking analysis. We analyzed 111 samples from 12 bamboo species collected from different altitudinal ranges using liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). We used multivariate and univariate statistical analyses to identify the metabolites that showed significant differences in the altitude environments. Additionally, we used the Global Natural Products Social Molecular Networking (GNPS) web platform to perform chemical mapping by comparing the metabolome among the studied species and the reference spectra from its database. The results showed 89 differential metabolites between the altitudinal ranges investigated, wherein high altitude environments significantly increased the profile of flavonoids. While, low altitude environments significantly boosted the profile of cinnamic acid derivatives, particularly caffeoylquinic acids (CQAs). MolNetEnhancer networks confirmed the same differential molecular families already found, revealing metabolic diversity. Overall, this study provides the first report of variations induced by altitude in the chemical profile of bamboo species. The findings may possess fascinating active biological properties, thus offering an alternative use for bamboo.
