Epidemiological studies have identified an inverse association between cancer and dementia. Underlying methodological biases have been postulated, yet no studies have systematically investigated the potential for each source of bias within a single dataset. We used the UK Biobank to compare estimates for the cancer-dementia association using different analytical specifications designed to sequentially address multiple sources of bias, including competing risk of death, selective survival, confounding bias, and diagnostic bias. We included 140,959 UK Biobank participants aged ≥ 55 without dementia before enrollment and with linked primary care data. We used cancer registry data to identify cancer cases prevalent before UK Biobank enrollment and incident cancer diagnosed after enrollment. We used Cox models to evaluate associations of prevalent and incident cancer with all-cause dementia, Alzheimers disease (AD), and vascular dementia. We used time-varying models to evaluate diagnostic bias. Over a median follow-up of 12.3 years, 3,310 dementia cases were diagnosed. All-site incident cancer was positively associated with all-cause dementia incidence (hazard ratio [HR] = 1.14, 95% CI: 1.02-1.29), but prevalent cancer was not (HR = 1.04, 95% CI: 0.92-1.17). Results were similar for vascular dementia. AD was not associated with prevalent or incident cancer. Dementia diagnosis was substantially elevated in the first year after cancer diagnosis (HR = 1.83, 95% CI: 1.42-2.36), after which the association attenuated to null, suggesting diagnostic bias. Following a cancer diagnosis, health care utilization or cognitive consequences of diagnosis or treatment may increase chance of receiving a dementia diagnosis, creating potential diagnostic bias in electronic health records-based studies.

Abstract Introduction Perforated peptic ulcer is the worst complication of peptic ulcer disease whose burden is disproportionately higher in low-income settings. However, there is paucity of published data on the patterns of perforated peptic ulcer in the region. The aim of this study was to determine the factors associated with anatomical patterns of peptic ulcer perforation, as well as the clinical, socio-demographic, and anatomical patterns among patients in Uganda. Methods This was a cross sectional study that enrolled 81 consecutive patients with perforated peptic ulcers. Using a structured pretested questionnaire the social demographic and clinical characteristics were obtained. At surgery, the patterns of the perforations were determined. Logistic regression was done in SPSS version 22 to determine the factors associated with the anatomical patterns. Results Perforated peptic ulcer disease was more prevalent among males (79.5%), peasants (56.8%) and those from rural areas (65.4%). Majority of study participants were of blood group O (43.2%). Gastric perforations were more common (74.1%). Majority of the perforations were found anteriorly (81.5%). Being a casual laborer was independently associated with lower odds of having a gastric perforation compared to being a peasant farmer (P

Abstract Objective The immunisation programme in Zambia remains one of the most effective public health programmes. Its financial sustainability is, however, uncertain. Using administrative data on immunisation coverage rate, vaccine utilisation, the number of health facilities and human resources, expenditure on health promotion, and the provision of outreach services from 24 districts, we used Data Envelopment Analysis to determine the level of technical efficiency in the provision of immunisation services. Based on our calculated levels of technical efficiency, we determined the available fiscal space for immunisation. Results Out of the 24 districts in our sample, 9 (38%) were technically inefficient in the provision of immunisation services. The average efficiency score, however, was quite high, at 0.92 (CRS technology) and 0.95 (VRS technology). Based on the calculated level of technical efficiency, we estimated that an improvement in technical efficiency can save enough vaccine doses to supply between 5 and 14 additional districts. The challenge, however, lies in identifying and correcting for the sources of technical inefficiency.

Abstract Background Common bean breeders strive to deliver farmer- and consumer-preferred varieties that are well-adapted to distinct production environments, changing markets and end uses. However, there is information gap on the key traits that customers prefer and are willing to pay for. This paper examined the preferences and willingness to pay for reduced cooking time and other selected traits in the Ugandan bean markets using a choice experiment data elicited from 1152 urban and rural bean consuming households. A latent class model was used to assess preferences and the willingness to pay for reduced cooking time. Results Results indicated that taste, cooking time, bean swelling on cooking, and grain color were the preferred attributes in decreasing order among non-bean-producers. About 72% of the urban consumers were willing to pay 41 shillings, 53 shillings and 42 shillings above prices for reduction in cooking time from 120 (status quo) to 90, 75, and 60 min, respectively. For consumers who also grow their beans for food and surplus for sale, reduced cooking time is important but not as much as yield and climate resilience. The study identified four distinct customer segments—two among bean-producing households and two among non-bean-producing households. Gender, education, level of altruism/openness to change, household economic status, and price sensitivity were the major factors influencing segment membership. Conclusions The study findings demonstrated that breeding to reduce cooking time will generate a significant social savings in terms of less cooking fuel, water and time, but cooking time ought to be considered alongside other attributes preferred by consumers and farmers to succeed. Results also suggest that women urban consumers attach more importance to higher levels of intrinsic traits (non-visible but experienced by consumers) compared to men—thus promotional campaigns popularizing new varieties should target women to stimulate demand.

Alcohol use is especially problematic for people living with HIV (PLWH) and was likely to be impacted by the coronavirus disease (COVID-19) pandemic and its restrictions. In a study of PLWH with latent tuberculosis infection, we measured unhealthy alcohol use with the Alcohol Use Disorders Identification Test (AUDIT-C), phosphatidylethanol (PEth) and bar attendance. We analyzed data collected before and after COVID-19 restrictions, and used Generalized Estimating Equations (GEE) logistic regression models to evaluate changes in unhealthy alcohol use. While bar attendance declined from 57.0% before to 38.3% after the restrictions started, multivariable analysis controlling for bar use showed a significant increase in unhealthy alcohol use; the adjusted odds ratio for unhealthy drinking before versus after the restrictions started was 1.37 (95% CI: 0.89-2.12) which increased to 1.64 (95% CI: 1.08-2.50) when bar attendance was added to the model. Decline in bar attendance did not decrease unhealthy alcohol use.

Biology (General) ,QH301-705.5 - Abstract
Abstract Proposed mechanisms of zoonotic virus spillover often posit that wildlife transmission and amplification precede human outbreaks. Between 2006 and 2012, the palm Raphia farinifera, a rich source of dietary minerals for wildlife, was nearly extirpated from Budongo Forest, Uganda. Since then, chimpanzees, black-and-white colobus, and red duiker were observed feeding on bat guano, a behavior not previously observed. Here we show that guano consumption may be a response to dietary mineral scarcity and may expose wildlife to bat-borne viruses. Videos from 2017–2019 recorded 839 instances of guano consumption by the aforementioned species. Nutritional analysis of the guano revealed high concentrations of sodium, potassium, magnesium and phosphorus. Metagenomic analyses of the guano identified 27 eukaryotic viruses, including a novel betacoronavirus. Our findings illustrate how “upstream” drivers such as socioeconomics and resource extraction can initiate elaborate chains of causation, ultimately increasing virus spillover risk.

Science - Abstract
Abstract Pig-to-human xenotransplantation is rapidly approaching the clinical arena; however, it is unclear which immunomodulatory regimens will effectively control human immune responses to pig xenografts. Here, we transplant a gene-edited pig kidney into a brain-dead human recipient on pharmacologic immunosuppression and study the human immune response to the xenograft using spatial transcriptomics and single-cell RNA sequencing. Human immune cells are uncommon in the porcine kidney cortex early after xenotransplantation and consist of primarily myeloid cells. Both the porcine resident macrophages and human infiltrating macrophages express genes consistent with an alternatively activated, anti-inflammatory phenotype. No significant infiltration of human B or T cells into the porcine kidney xenograft is detectable. Altogether, these findings provide proof of concept that conventional pharmacologic immunosuppression may be able to restrict infiltration of human immune cells into the xenograft early after compatible pig-to-human kidney xenotransplantation.

Abstract Background Human papillomavirus (HPV) is a common sexually transmitted infection and the leading cause of cervical cancer. The HPV vaccine is a safe and effective way to prevent HPV infection. In Zambia, the vaccine is given during Child Health Week to girls aged 14 years who are in and out of school in two doses over two years. The focus of this evaluation was to establish the cost to administer a single dose of the vaccine as well as for full immunisation of two doses. Methods This work was part of a broader study on assessing HPV programme implementation in Zambia. For HPV costing aspect of the study, with a healthcare provider perspective and reference year of 2020, both top-down and micro-costing approaches were used for financial costing, depending on the cost data source, and economic costs were gathered as secondary data from Expanded Programme for Immunisation Costing and Financing Project (EPIC), except human resource costs which were gathered as primary data using existing Ministry of Health salary scales and reported time spent by different health cadres on activities related to HPV vaccination. Data was collected from eight districts in four provinces, mainly using a structured questionnaire, document reviews and key informant interviews with staff at national, provincial, district and health facility levels. Administrative coverage rates were obtained for each district. Results Findings show that schools made up 53.3% of vaccination sites, community outreach sites 30.9% and finally health facilities 15.8%. In terms of coverage for 2020, for the eight districts sampled, schools had the highest coverage at 96.0%. Community outreach sites were at 6.0% of the coverage and health facilities accounted for only 1.0% of the coverage. School based delivery had the lowest economic cost at USD13.2 per dose and USD 28.1 per fully immunised child (FIC). Overall financial costs for school based delivery were US$6.0 per dose and US$12.4 per FIC. Overall economic costs taking all delivery models into account were US$23.0 per dose and US$47.6 per FIC. The main financial cost drivers were microplanning, supplies, service delivery/outreach and vaccine co-financing; while the main economic cost drivers were human resources, building overhead and vehicles. Nurses, environmental health technicians and community-based volunteers spent the most time on HPV related vaccination activities compared to other cadres and represented the greatest human resource costs. Conclusions The financial cost of HPV vaccination in Zambia aligns favourably with similar studies conducted in other countries. However, the economic costs appear significantly higher than those observed in most international studies. This discrepancy underscores the substantial strain placed on healthcare resources by the program, a burden that often remains obscured. While the vaccine costs are currently subsidized through the generous support of Gavi, the Vaccine Alliance, it’s crucial to recognize that these expenses pose a considerable threat to long-term sustainability. Consequently, countries such as Zambia must proactively devise strategies to address this challenge.

The study explored the push and pull factors driving Ugandan domestic workers to migrate to Saudi Arabia. The research paradigm employed was social constructivism, where individuals seek to understand their world and develop meanings based on their experiences. A qualitative approach using a phenomenological research design was utilised. Data was collected from a sample of eighteen (18) respondents through unstructured interviews to identify the factors contributing to the migration of Ugandan domestic workers to Saudi Arabia. Thematic analysis was conducted during data analysis. The migration factors were presented in concept maps created using Nvivo 10.0. The study uncovered that push factors varied from person to person, but major ones included poverty, unemployment, school dropout, family obligations, marital neglect, domestic violence, personal development goals, poor working conditions, work-related challenges, peer influence, and single parenting. Pull factors include the influence of Arabian family culture that promotes the demand for maids, bilateral labour agreements, adventure, attractive job prospects, free travel documents, cost-effective job processes, and an easy migration process. The study concluded that without effectively addressing push factors to provide long-term solutions, the migration of Ugandan domestic workers to Saudi Arabia will persist. It is recommended that the Government of Uganda take steps to create a conducive environment with satisfying employment opportunities for these young individuals to reduce the number of people seeking jobs outside Uganda. This involves generating employment opportunities to regulate internal domestic work and make it highly profitable, thereby encouraging young people to remain in Uganda.

Medicine ,Science - Abstract
Abstract In Uganda, the challenge of generating and timely reporting essential antimicrobial resistance (AMR) data has led to overreliance on empirical antibiotic therapy, exacerbating the AMR crisis. To address this issue, this study aimed to adapt a one-step AMR testing protocol alongside an SMS (Short Message Service) result relay system (SRRS), with the potential to reduce the turnaround time for AMR testing and result communication from 4 days or more to 1 day in Ugandan clinical microbiology laboratories. Out of the 377 samples examined, 54 isolates were obtained. Notably, E. coli (61%) and K. pneumoniae (33%) were the most frequently identified, majority testing positive for ESBL. Evaluation of three AMR testing protocols revealed varying sensitivity and specificity, with Protocol A (ChromID ESBL-based) demonstrating high sensitivity (100%) but no calculable specificity, Protocol B (ceftazidime-based) showing high sensitivity (100%) and relatively low specificity (7.1%), and Protocol C (cefotaxime-based) exhibiting high sensitivity (97.8%) but no calculable specificity. ESBL positivity strongly correlated with resistance to specific antibiotics, including cefotaxime, ampicillin, and aztreonam (100%), cefuroxime (96%), ceftriaxone (93%), and trimethoprim sulfamethoxazole (87%). The potential of integrating an SRRS underscored the crucial role this could have in enabling efficient healthcare communication in AMR management. This study underscores the substantial potential of the tested protocols for accurately detecting ESBL production in clinical samples, potentially, providing a critical foundation for predicting and reporting AMR patterns. Although considerations related to specificity warrant careful assessment before widespread clinical adoption.

Law - Abstract
The main aim of this study is to find out how the existing legislation can adequately address the challenge of gender inequality in employment of women in Uganda. The violations of women’s employment rights originate in the virtually universal history of unequal power relations between men and women. The findings of the study are that the existing regulatory framework on employment in Uganda though adequate, its enforcement is still a challenge. Major emphasis has been directed towards the use of gender-neutral non-sexist language whereas other factors that interfere with the regime have remained unchanged. The study further makes significant findings that gender inequality in the workplace takes many forms namely; denial of maternity leave, unequal pay, wrongful dismissal, denial of maternity leave, discrimination at work, sexual harassment, among others. The denial of such rights perpetuates gender inequality in the field of employment. The study makes relevant recommendations namely; strategic litigation, enforcement of existing laws, affirmative action, mainstreaming gender in employment sector and reform of traditional beliefs among others.

Livestock farming is vital to global food systems, but the misuse of antibiotics in this sector has raised concerns about its role in the emergence of antimicrobial resistance - now a public health issue. Addressing the misuse of antibiotics requires an understanding of usage patterns and determinants among livestock farmers. This study investigated antibiotic use among livestock farmers in Uganda, examining the frequency of use and factors influencing usage with data from the 2018 Uganda Annual Agricultural Survey. Descriptive results showed that on average one in every three livestock keepers had used antibiotics in the previous year, with 15% of them using antibiotics at least every month in the previous year. Regression analysis results revealed that, among other factors, production systems (keeping cattle, keeping exotic livestock, and herd size) and keepers’ perceptions of the continued efficacy of antibiotics in controlling target diseases even with continuous use significantly influenced the decision to use antibiotics and the frequency with which they were used. The results of this study confirmed the growing concern that antibiotic use in Uganda is no longer limited to humans but has significantly expanded to the livestock sector too. The results further affirmed that antibiotic use in livestock production has reached significant levels that require streamlining from a public health perspective. The study recommends strengthening veterinary education and increasing public awareness of appropriate antibiotic use to combat wrong perceptions towards antibiotic use and encourage safe use.

Background Globally, more than half of women take medicines whilst breastfeeding. Data concerning the exposure of the breastfed infant to drugs and any related risks are sparce. Lactation studies are only rarely performed close to licensing for medicines anticipated to be widely used in women of childbearing age. Medicines taken by breastfeeding mothers on tuberculosis (TB) treatment can be transferred to the breastfed infant. Potential effects of anti-tuberculosis medicines on nursing infants are not well understood. Similarly, women face mental health challenges while taking medications, including postpartum depression, hence the need to assess the psychological behavior of a breastfeeding woman. Potential risks are the development of adverse drug effects in the breastfed infant and selection for resistance, whereas potential benefits might include exposure to potentially prophylactic concentrations of the drug. Pharmacokinetic studies are therefore necessary to understand this situation fully. Methods This study will enroll 20 mothers receiving first-line anti-tuberculosis medicines, together with their breastfed infants, with the aim of characterizing the breastmilk transfer of the medicines from the mother to the infants. Samples of maternal blood, breastmilk, and breastfeeding infant’s blood will be obtained at specific time points for bioanalysis of drug concentrations. Pharmacokinetic data will be analyzed using a population pharmacokinetic approach. Additionally, the study will assess the psychological status of breastfeeding women and the well-being of their infants. Maternal depression is linked to long-term negative consequences for the infant’s physiological regulation, poor growth-promoting setting for the infants, and inappropriate interactive conduct, characterized by low compassion, constrained range of emotional expression, and varying provision of the infant’s budding engagement. Conclusions This study will provide the first systematic characterization of mother-to-infant transfer of first-line anti-tuberculosis medicines through breast milk. A mathematical pharmacokinetics model characterizing plasma-to-breastmilk transfer of rifampicin, isoniazid, ethambutol, and pyrazinamide will be developed and used to characterize infant exposure through breast milk. Our findings will contribute towards treatment optimization in breastfeeding and provide a framework to foster other lactation pharmacokinetic studies.

IntroductionYoung migrants may engage in risky behaviours due to social, economic, and psychological challenges as they try to “get by” in their new host communities. This can result in unintended pregnancies, sexually transmitted infections including HIV, and poor mental health outcomes.During a study to test the feasibility and acceptability of an early intervention to reduce the harm of patterns of risk associated with migration, we assessed access to and utilization of sexual and reproductive health services (SRH) among recent migrants (14–24 years) in south-western Uganda.MethodsThe intervention conducted in 2022/23 involved training peer supporters to provide referral advice and support to young people. Between March–November 2022, 20 young migrants (11 males and 9 females) were purposively selected to participate in two in-depth interviews each to explore their experiences during the intervention. Data were analysed thematically.ResultsWomen engaged in transactional sex to supplement their low pay while men got involved in risky behaviour once they had earned some money. Many suffered from sexually transmitted infections-related symptoms, were at risk for HIV infection and some women had fears of unwanted pregnancy. While some tried to seek for SRH services from public facilities, poor health service delivery such as long queues and shortages of drugs, discouraged them from going there. Young people tried to access treatment from private facilities but could not afford the costs. The intervention increased knowledge about SRH and supported young people to access services from the public health facilities at no cost thus increasing utilization.ConclusionSexual health risks were experienced differently by women and men. The women were likely to experience symptoms related to sexually transmitted infections (including HIV) much earlier than men and this could increase their likelihood to engage with SRH services. The intervention served to increase men's readiness to access SRH services by providing them at a time and place that is convenient. Recognizing the different risk profiles of young people is important in tailoring appropriate interventions to promote equitable access and utilization of SRH services for both genders in this vulnerable population.

BackgroundCOVID-19-related lockdowns and other public health measures may have differentially affected the quality of life (QOL) of older people with and without human immunodeficiency virus (HIV) in rural Uganda.MethodsThe Quality of Life and Aging with HIV in Rural Uganda study enrolled people with and without HIV aged over 49 from October 2020 to October 2021. We collected data on COVID-19-related stressors (behavior changes, concerns, interruptions in health care, income, and food) and the participants' QOL. We used linear regression to estimate the associations between COVID-19-related stressors and QOL, adjusting for demographic characteristics, mental and physical health, and time before vs after the lockdown during the second COVID-19 wave in Uganda. Interaction between HIV and COVID-19-related stressors evaluated effect modification.ResultsWe analyzed complete data from 562 participants. Mean age was 58 (standard deviation (SD) = 7); 265 (47%) participants were female, 386 (69%) were married, 279 (50%) had HIV, and 400 (71%) were farmers. Those making ≥5 COVID-19-related behavior changes compared to those making ≤2 had worse general QOL (estimated linear regression coefficient (b) = - 4.77; 95% confidence interval (CI) = -6.61, -2.94) and health-related QOL (b = -4.60; 95% CI = -8.69, -0.51). Having access to sufficient food after the start of the COVID-19 pandemic (b = 3.10, 95% CI = 1.54, 4.66) and being interviewed after the start of the second lockdown (b = 2.79, 95% CI = 1.30, 4.28) were associated with better general QOL. Having HIV was associated with better health-related QOL (b = 5.67, 95% CI = 2.91,8.42). HIV was not associated with, nor did it modify the association of COVID-19-related stressors with general QOL.ConclusionsIn the context of the COVID-19 pandemic in an HIV-endemic, low-resource setting, there was reduced QOL among older Ugandans making multiple COVID-19 related behavioral changes. Nonetheless, good QOL during the second COVID-19 wave may suggest resilience among older Ugandans.

Identifying factors associated with alcohol use changes during pregnancy is important for developing interventions for people with HIV (PWH). Pregnant PWH (n = 202) initiating antiretroviral therapy in Uganda and South Africa completed two assessments, 6 months apart (T1, T2). Categories were derived based on AUDIT-C scores: "no use" (AUDIT-C = 0 at T1 and T2), "new use" (AUDIT-C = 0 at T1, >0 at T2), "quit" (AUDIT-C > 0 at T1, =0 at T2), and "continued use" (AUDIT-C > 0, T1 and T2). Factors associated with these categories were assessed. Most participants had "no use" (68%), followed by "continued use" (12%), "quit" (11%), and "new use" (9%). Cohabitating with a partner was associated with lower relative risk of "continued use." Borderline significant associations between food insecurity and higher risk of "new use" and between stigma and reduced likelihood of "quitting" also emerged. Alcohol use interventions that address partnership, food security, and stigma could benefit pregnant and postpartum PWH.

The samples were then subjected to culture and sensitivity testing. The investigative framework for antimicrobial stewardship practices (IFAP) was used as a participatory tool to generate data through interviews and observations on antimicrobial use, drivers for use, players, and actions following non-responsive treatment outcomes.Results: The cultures done on 290 cloacal swabs yielded a total of 273 Escherichia coli isolates (94.1% recovery rate) which were tested in vitro for their sensitivity to different antibiotics. The prevalence of multi-drug resistant E. coli was 59.3% (162/273). A high prevalence of resistance to tetracycline (91.6%, n = 250) and trimethoprim sulphamethoxazole (70.3%, n = 192) was noted. In this collection of isolates, the prevalence of molecular determinants associated with the predominant phenotypes was; tetA (79.3%; 138/174), tetB (17.2%; 30/174), tetC (7.5%; 13/174), sul1 (11.5%; 20/174), and sul2 (60.3%; 105/174). Responses derived using the IFAP revealed several vices related to misuse and overuse of antibiotics, a threat to the poultry industry. The farmers also reported habits of selling off sick birds for slaughter when treatment outcomes were non-responsive. Such a practice could drive dissemination of antimicrobial resistant organisms and antibiotic residues to the consumers of those poultry products.Conclusion: The IFAP tool was useful and can be modified, and adopted for use in engaging agricultural communities in participatory AMR surveillance. A high carriage of multi-drug resistant E. coli was detected in the birds. On these farms, the worrying antimicrobial stewardship practices discovered could be sponsoring the emergence and spread of antimicrobial resistant bacteria in the Ugandan context.Keywords: antimicrobial resistance, Escherichia coli of chicken, antimicrobial stewardship, Uganda’s poultry sector

Abstract Background The Human Immunodeficiency Virus (HIV) remains a global health burden, and despite the advancements in antiretroviral therapy and various strategies employed to curb HIV infections, the incidence of HIV remains disproportionately high among women. Therefore, this study aimed to determine the prevalence of the risk factors for the acquisition of HIV among sexually active women in Rwanda. Methods Secondary data from the 2020 Rwanda Demographic Health Survey, comprising 10,684 sexually active women, was used. Multistage stratified sampling was employed to select the study participants. Multivariable logistic regression was conducted to determine the associated risk factors using the SPSS (version 25). Results Of the 10,684 sexually active women, 28.7% (95% confidence interval (CI): 27.5–29.4) had at least one risk factor for HIV acquisition. Having no education (AOR = 3.65, 95%CI: 2.16–6.16), being unmarried (AOR = 4.50, 95%CI: 2.47–8.21), being from female-headed households (AOR = 1.75, 95%CI: 1.42–2.15), not having health insurance (AOR = 1.34, 95%CI: 1.09–1.65), no HIV test history (AOR = 1.44, 95%CI: 1.01–2.08), being from the poorest wealth quintile (AOR = 1.61, 95%CI: 1.14–2.27) and lack of exposure to mass media (AOR = 1.30, 95%CI: 1.07–1.58) were associated with higher odds of exposure to at least one HIV acquisition risk factor. In contrast, age groups of 25–34 (AOR = 0.56, 95%CI: 0.44–0.71) and 35–44 years (AOR = 0.62, 95%CI: 0.48–0.80), rural residence (AOR = 0.63, 95%CI: 0.49–0.81) and being from the western region (AOR = 0.67, 95%CI: 0.48–0.94) were associated with less odds of exposure to at least one HIV acquisition risk factor. Conclusion More than a quarter of sexually active women in Rwanda had exposure to at least one risk factor for HIV acquisition. There is a need to maximize the use of mass media in disseminating HIV prevention and behavioral change messages. Engagement of religious leaders and promotion of HIV testing, especially among the never-testers, may be vital strategies in successful HIV prevention programs.

Identifying persons who have newly acquired HIV infections is critical for characterizing the HIV epidemic direction. We analyzed pooled data from nationally representative Population-Based HIV Impact Assessment surveys conducted across 14 countries in Africa for recent infection risk factors. We included adults 15–49 years of age who had sex during the previous year and used a recent infection testing algorithm to distinguish recent from long-term infections. We collected risk factor information via participant interviews and assessed correlates of recent infection using multinomial logistic regression, incorporating each surveyʼs complex sampling design. Compared with HIV-negative persons, persons with higher odds of recent HIV infection were women, were divorced/separated/widowed, had multiple recent sex partners, had a recent HIV-positive sex partner or one with unknown status, and lived in communities with higher HIV viremia prevalence. Prevention programs focusing on persons at higher risk for HIV and their sexual partners will contribute to reducing HIV incidence.

Rukiga (Bantu, JE14) generally does not have a dedicated morphological system to express mirativity, that is, speaker’s surprise at an unexpected occurrence. Nevertheless, using elicited data, I show that there are various non-dedicated linguistic tools that the language employs to express the speaker’s surprise. This paper discusses object marker doubling, predicate doubling, and the particles -o and ku, which convey mirativity as a secondary function because they have other various roles they play in the language. Hence, mirative interpretation is context-dependent. The findings indicate that the four strategies discussed can be combined for a reinforced mirative interpretation.

Abstract Background In 2015, the World Health Organization recommended that all people living with HIV begin antiretroviral treatment (ART) regardless of immune status, a policy known as ‘Treat-All to end AIDS’, commonly referred to as Treat-All. Almost all low- and middle-income countries adopted this policy by 2019. This study describes how linkage to treatment of newly diagnosed persons changed between 2015 and 2018 and how complementary policies may have similarly increased linkage for 13 African countries. These countries adopted and implemented Treat-All policies between 2015 and 2018 and were supported by the U.S. Government’s President’s Emergency Plan for AIDS Relief (PEPFAR). The focuses of this research were to understand 1) linkage rates to ART initiation before and after the adoption of Treat-All in each country; 2) how Treat-All implementation differed across these countries; and 3) whether complementary policies (including same-day treatment initiation, task-shifting, reduced ART visits, and reduced ART pickups) implemented around the same time may have increased ART linkage. Methods HIV testing and treatment data were collected by PEPFAR country programs in 13 African countries from 2015 to 2018. These countries were chosen based on the completeness of policy data and availability of program data during the study period. Program data were used to calculate proxy linkage rates. These rates were compared relative to the Treat All adoption period and the adoption of complementary policies. Results The 13 countries experienced an average increase in ART linkage of 29.3% over the entire study period. In examining individual countries, all but two showed increases in linkage to treatment immediately after Treat All adoption. Across all countries, those that had adopted four or more complementary policies showed an average increased linkage of 39.8% compared to 13.9% in countries with fewer than four complementary policies. Conclusions Eleven of 13 country programs examined in this study demonstrated an increase in ART linkage after Treat-All policy adoption. Increases in linkage were associated with complementary policies. When exploring new public health policies, policymakers may consider which complementary policies might also help achieve the desired outcome of the public health policy.

Abstract Background While laboratory testing for infectious diseases such as COVID-19 is the surveillance gold standard, it is not always feasible, particularly in settings where resources are scarce. In the small country of Lesotho, located in sub-Saharan Africa, COVID-19 testing has been limited, thus surveillance data available to local authorities are limited. The goal of this study was to compare a participatory influenza-like illness (ILI) surveillance system in Lesotho with COVID-19 case count data, and ultimately to determine whether the participatory surveillance system adequately estimates the case count data. Methods A nationally-representative sample was called on their mobile phones weekly to create an estimate of incidence of ILI between July 2020 and July 2021. Case counts from the website Our World in Data (OWID) were used as the gold standard to which our participatory surveillance data were compared. We calculated Spearman’s and Pearson’s correlation coefficients to compare the weekly incidence of ILI reports to COVID-19 case count data. Results Over course of the study period, an ILI symptom was reported 1,085 times via participatory surveillance for an average annual cumulative incidence of 45.7 per 100 people (95% Confidence Interval [CI]: 40.7 – 51.4). The cumulative incidence of reports of ILI symptoms was similar among males (46.5, 95% CI: 39.6 – 54.4) and females (45.1, 95% CI: 39.8 – 51.1). There was a slightly higher annual cumulative incidence of ILI among persons living in peri-urban (49.5, 95% CI: 31.7 – 77.3) and urban settings compared to rural areas. The January peak of the participatory surveillance system ILI estimates correlated significantly with the January peak of the COVID-19 case count data (Spearman’s correlation coefficient = 0.49; P

Determiner spreading, the phenomenon whereby adnominal modifiers carry an ‘additional’ determiner, has been studied extensively for a variety of languages, most notably Greek, Semitic, and Scandinavian languages. Interestingly, the same phenomenon occurs in the Bantu language Rukiga. We show how the Rukiga augment is parallel to the Greek determiner in the context of modification, and how it triggers a restrictive reading when present on a larger class of modifiers than familiar so far: relative clauses, adjectives, possessives, and certain quantifiers. Considering its morphosyntactic and interpretational properties, we propose that the variation in the presence versus absence of the augment on modifiers is due to different underlying structures, applying an analysis of determiner spreading in terms of a reduced relative clause structure.

Abstract Background Adequate sexual and reproductive health literacy (SRHL) among young people has been linked to informed sexual behaviours. Studies on SRHL have largely been conducted among the general adolescent population. Little is known about youth aged 15-24 years living with human immunodeficiency virus (YLHIV). There is a possible lack of SRHL in this population, considering the high rate of teenage pregnancies and unprotected sex reported by YLHIV. This study aimed to assess the prevalence and associated personal and environmental factors for SRHL among YLHIV at a high-volume urban HIV Clinic in Uganda. Methods Through a cross-sectional survey, YLHIV receiving routine HIV care services at Baylor-Uganda HIV Clinic were interviewed using an adapted European Health Literacy Survey (HLS-EU). Using simple random sampling, eligible youth who received HIV care services between August and November 2019 were enrolled in the study. SRHL scores were computed using the HLS-EU index method; and individuals whose scores ranged from 34 to 50 were considered health literate. We used descriptive statistics to determine the prevalence.

A 68-year-old male with a history of end-stage renal disease and latent tuberculosis on isoniazid (INH), and no psychiatric history presented with a five-day history of anorexia, fatigue, and nausea. Physical exam in the emergency department was notable for somnolence, right upper extremity tremor, and diffuse abdominal pain. Initial workup revealed an anion gap metabolic acidosis with elevated lactate, prompting admission to the general ward for empiric IV antibiotics for suspected bacteremia from his permacath. Within a few hours of admission, he became increasingly encephalopathic and had two episodes of copious hematemesis. Repeat studies revealed a cholestatic pattern of liver injury and new-onset coagulopathy. With an overall clinical picture consistent with fulminant hepatic failure, our pharmacy team initiated a comprehensive pill count of all his medications, which established that he had been inadvertently taking up to six times the recommended dose of INH. With INH discontinuation and supportive therapy, he improved and was discharged on hospital day eight. Our experience provides lessons in the timely recognition and management of this rarely reported toxidrome in the United States.

- Abstract
The present study was conducted to investigate the relationship between school-based practices and students' discipline in secondary schools. The school-based practices that were focused on were: Managing access procedures, managing students' identity and sensitisation of students on rules and regulations. The study adopted a correlational research design in order to establish the relationship between the dependent and independent variables in question. A total of 351 students and 93 teachers were selected using simple random and stratified sampling. A closed ended questionnaire was administered to both respondents and the data obtained were entered and analyzed using the statistical package for social scientists (SPSS). It was found that the sensitization activities and managing students' identity had a positive but low effect on the students' discipline while managing access procedures had a slightly high influence. The study generally showed that, there is a moderate positive relationship (r = 0.559) between the school-based practices and the students' discipline. This was tested to be statistically significant at 0.01 level with p<0.05.

To decipher the evolution of the hominoid brain and its functions, it is essential to conduct comparative studies in primates, including our closest living relatives. However, strong ethical concerns preclude in vivo neuroimaging of great apes. We propose a responsible and multidisciplinary alternative approach that links behavior to brain anatomy in non-human primates from diverse ecological backgrounds. The brains of primates observed in the wild or in captivity are extracted and fixed shortly after natural death, and then studied using advanced MRI neuroimaging and histology to reveal macro- and microstructures. By linking detailed neuroanatomy with observed behavior within and across primate species, our approach provides new perspectives on brain evolution. Combined with endocranial brain imprints extracted from computed tomographic scans of the skulls these data provide a framework for decoding evolutionary changes in hominin fossils. This approach is poised to become a key resource for investigating the evolution and functional differentiation of hominoid brains.

As antiretroviral treatment (ART) coverage for people living with HIV (PLHIV) increases, HIV programmes require up-to-date information about evolving HIV risk behaviour and transmission risk, including those with low-level viremia (LLV; >50 to ≤1000 copies/mL), to guide prevention priorities. We aimed to assess differences in sexual risk behaviours, distribution of viral load (VL) and proportion of transmission across PLHIV subgroups. We analysed data from Population-based HIV Impact Assessment surveys in 14 sub-Saharan African countries during 2015-2019. We estimated adjusted prevalence ratios (aPR) of self-reported HIV high-risk behaviour (multiple partners and condomless sex) across cascade stages via generalised estimation equations. We modelled the proportions of transmission from each subgroup using relative self-reported sexual risk, a Hill function for transmission rate by VL, and proportions within cascade stages from surveys and UNAIDS country estimates for 2010-2020. Compared to PLHIV with undetectable VL (≤50 copies/mL), undiagnosed PLHIV (aPR women: 1.28 [95% CI: 1.08-1.52]; men: 1.61 [1.33-1.95]) and men diagnosed but untreated (2.06 [1.52-2.78]) were more likely to self-report high-risk sex. High-risk behaviour was not significantly associated with LLV. Mean VL was similar among undiagnosed, diagnosed but untreated, and on ART but non-suppressed sub-groups. Across surveys, undiagnosed and diagnosed but untreated contributed most to transmission (40-91% and 1-41%, respectively), with less than 1% from those with LLV. Between 2010 and 2020, the proportion of transmission from individuals on ART but non-suppressed increased. In settings with high ART coverage, effective HIV testing, ART linkage, and retention remain priorities to reduce HIV transmission. Persons with LLV are an increasing share of PLHIV but their contribution to HIV transmission was small. Improving suppression among PLHIV on ART with VL ≥1000 copies/mL will become increasingly important.

Public aspects of medicine ,RA1-1270 - Abstract
Antibacterial resistance (ABR) is a major public health threat. An important accelerating factor is treatment-seeking behaviour, including inappropriate antibiotic (AB) use. In many low- and middle-income countries (LMICs) this includes taking ABs with and without prescription sourced from various providers, including health facilities and community drug sellers. However, investigations of complex treatment-seeking, AB use and drug resistance in LMICs are scarce. The Holistic Approach to Unravel Antibacterial Resistance in East Africa (HATUA) Consortium collected questionnaire and microbiological data from adult outpatients with urinary tract infection (UTI)-like symptoms presenting at healthcare facilities in Kenya, Tanzania and Uganda. Using data from 6,388 patients, we analysed patterns of self-reported treatment seeking behaviours ('patient pathways') using process mining and single-channel sequence analysis. Among those with microbiologically confirmed UTI (n = 1,946), we used logistic regression to assess the relationship between treatment seeking behaviour, AB use, and the likelihood of having a multi-drug resistant (MDR) UTI. The most common treatment pathway for UTI-like symptoms in this sample involved attending health facilities, rather than other providers like drug sellers. Patients from sites in Tanzania and Uganda, where over 50% of patients had an MDR UTI, were more likely to report treatment failures, and have repeat visits to providers than those from Kenyan sites, where MDR UTI proportions were lower (33%). There was no strong or consistent relationship between individual AB use and likelihood of MDR UTI, after accounting for country context. The results highlight the hurdles East African patients face in accessing effective UTI care. These challenges are exacerbated by high rates of MDR UTI, suggesting a vicious cycle of failed treatment attempts and sustained selection for drug resistance. Whilst individual AB use may contribute to the risk of MDR UTI, our data show that factors related to context are stronger drivers of variations in ABR.
