IntroductionIn recent years, Volcanoes National Park has seen a rise in its wildlife population, primarily due to the diligent efforts of the Rwandan government in safeguarding endangered species, notably the mountain gorillas (Gorilla beringei spp. beringei). This population growth has led to a pressing need for more expansive habitats, ensuring these creatures have ample space, sustenance, and shelter for their wellbeing. Consequently, there are planned park expansion activities on the horizon. However, before initiating this expansion, a critical prelude involves identifying potential threats, particularly toxic substances stemming from agricultural activities in the surrounding environment of Volcanoes National Park.MethodsTo address this concern, a comprehensive study was conducted, aimed at pinpointing potential toxic hazards and assessing the awareness of the local population regarding the harm these hazards pose to wildlife species. Data was collected from individuals with no prior knowledge of the study using a pre-tested questionnaire. The questionnaire was divided into three sections: socio-demographic issues, potential toxic hazards assessment, and a section to determine awareness and risk of potential toxic hazards to humans, animals, and the environment. Respondents were selected based on specific criteria, which included being 18 years or older and residing within the National Volcano Park (NVP) area.ResultsThe study's findings revealed four main categories of potential toxic hazards, which include household chemicals, pharmaceutical products, agricultural pesticides, and poisonous plants. These hazards could jeopardize the health and survival of wildlife species if they consume or come into contact with them. Furthermore, the study exposed an inadequacy in the knowledge and skills of the local community in preventing these toxic hazards, which can result in death of wildlife species and ecosystem contamination and degradation.ConclusionStudy results also underscored the significance of education and training in enhancing the awareness of local communities concerning these toxic threats. Therefore, it is imperative to implement immediate measures to mitigate the adverse effects of these toxic hazards on wildlife species, especially in light of the planned park expansion.

Abstract Background Staphylococcus aureus (S. aureus) often colonizes the human skin, upper respiratory and genital tracts. In the female genital tract, it can be passed on to the newborn during vaginal delivery leading to either ordinary colonization, or neonatal infections notably umbilical stump sepsis, scalded skin syndrome, arthritis, or bacteraemia/sepsis. These infections are mediated by staphylococcal virulence factors such as (i) Staphylococcal Enterotoxins A, B, C, D, and E encoded by the sea, seb, sec, sed, see genes, (ii) Exfoliative Toxins A and B encoded by the eta and etb genes, (iii) Toxic Shock Syndrome Toxin 1 (TSST-1) encoded by the tst gene, (iv) Panton-Valentine Leukocidin (PVL) encoded by the pvl gene, and (v) Hemolysins alpha and delta encoded by the hla and hld genes, respectively. We determined the prevalence of S. aureus possessing one or more virulence factor genes and of methicillin resistant Staphylococcus aureus (MRSA) in this population. Methods This was a cross-sectional study, which used 85 S. aureus isolates from the Chlorohexidine (CHX) clinical trial study in Uganda. The isolates had been obtained by culturing vaginal swabs (VS) from 1472 women in labour, frozen at minus 80oC, then thawed, sub-cultured, and tested for the selected virulence genes sea, seb, sec, sed, see eta, etb, tst, pvl, hla and hld, and for the methicillin resistance determining gene (mecA). Data were analyzed using SPSS version 20. Results Of the 85 S. aureus isolates 13 (15.3%) were positive for one or more virulence factor genes, as follows: pvl 9/85 (10.6%), hld 5/85 (5.9%), sea 1/85 (1.2%) and seb genes 1/85 (1.2%). The other virulence genes (sec, sed, see, eta, etb, hla and tst) were not detected in any of the isolates. MRSA was detected in 55.3% (47/85) of the isolates, but only two of these carried the pvl virulence gene. Conclusion This study demonstrated that 15% of the S. aureus colonizing the female lower genital tract of mothers in labour in central Uganda carried one or more virulence genes, mostly pvl, indicating potential for newborn infection with S. aureus acquired in the maternal birth canal. More than half of the isolates were MRSA.

Abstract Background The state of a child’s nutrition is a critical indicator of their overall health and wellbeing. Public health still faces challenges from undernutrition, especially in developing nations across the globe. In Rwanda, around 33% of children aged under five years suffer from chronic undernutrition. Many factors, such as poverty, illiteracy, poor WASH practices, improper child feeding practices, and insufficient healthcare, are the leading causes of undernutrition. The study aims to assess infant and young child feeding practices, WASH, food security, and their association with the nutritional status of children under five years in Rwanda’s Western and Southern provinces. Methods A community-based cross-sectional study design was applied to study factors affecting the nutritional status of children under five years in 439 households in the Karongi, Nyabihu, and Nyamagabe districts of Rwanda. The study assessed anemia, stunting, underweight, and wasting indicators, and collected data was analyzed using SPSS version 25. Results The study findings indicate that among the children surveyed, 29.2% (128) were identified as stunted, 5.9% (26) were underweight, 2.3% (10) suffered from wasting, and 20.9% (31) had anemia. Factors associated with these conditions included larger household size [AOR = 2.108; 95% CI (1.016–4.371)], positively associated with stunting. Additionally, children from households where the head was above 60 years old were more likely to exhibit stunting [AOR = 4.809; 95% CI (1.513, 15.283)]. Furthermore, a high household dietary diversity score was positively linked to being underweight [AOR = 6.061; 95% CI (1.535,23.942)]. Conclusion Household characteristics like size, dietary diversity, and the age of the household head affect children’s nutritional status. Improving these conditions would enhance children’s nutritional status.

Abstract Objective Fourth-generation HIV Ag/Ab Combo assay is used for HIV screening of blood for transfusion in developing countries, however, the sensitivity of the assay is questionable during the acute phase of HIV infection. Thus, the study aimed to determine the effect of combining centrifugation with HIV-1 virion lysis on the sensitivity of the fourth-generation HIV Ag/Ab combo assay. Results When the 50 HIV-1 antibody-negative samples were run on the fourth-generation HIV Ag/Ab combo assay, 8 (16%) were positive following centrifugation, 13 (26%) were positive following lysis while 25 (50%) were positive after combining centrifugation with HIV-1 virion lysis.

ABSTRACT Background Responsive feeding among infants and young children (IYC) determines their food acceptance and adequate dietary intake, which enhances growth and developmental opportunities. However, little is known about responsive feeding practices among IYC in Rwanda. This study explored the status and barriers of responsive feeding practices among mothers from rural areas of Muhanga District in Rwanda. Method This descriptive longitudinal and exploratory mixed methods study was conducted among 29 mothers from 2 rural health centers in Muhanga District. Mothers were interviewed, and their interactions with children during lunch meals at 6, 9, and 12 months were observed. The interviews were recorded, transcribed, and thematically analyzed using Atlas.ti software. Results The study shows that the number of mothers who reported to verbally encourage their children to eat during feeding increased with the child's age. Less than half of mothers, at all three time points of data collection (at 6, 9, and 12 months), reported and were observed allowing their children to self‐feed, smiling and talking to them during feeding. The perceived major barriers to mother–child interaction during feeding were lack of time due to the burden of other responsibilities, and poverty. In addition, fear of messing up and food waste were barriers to child self‐feeding opportunities. Conclusion Findings indicate that responsive feeding was less practiced among study mothers due to lack of time, poverty, and fear of food waste during child self‐feeding. Nutrition interventions in this community should consider raising awareness of responsive feeding practices through education and encouraging mothers to devote sufficient time to interact with their children during feeding episodes.

ABSTRACT Background Dietary diversity is crucial for nutritional adequacy, particularly among women of reproductive age who have increased nutritional needs due to menstruation, pregnancy, and lactation. This is especially important in addressing anemia in Rwanda, which poses significant health risks for both mothers and children. This study assessed the dietary diversity, nutritional status, and related factors among Rwandan women engaged in agriculture. Methods In 2022, a cross‐sectional study in Nyamagabe, Karongi, and Nyabihu districts, Rwanda, focused on high malnutrition rates. Agriculture households with children under 5 were sampled using a multistage method. Data, including nutritional status via MUAC and dietary diversity via 24‐h recall, were collected digitally through Kobo Collect. Results The study included 439 respondents, with a mean age of 33 years. Among participants, 359 (81.8%) had low dietary diversity, with Nyamagabe having the highest proportion at 39%. Anemia prevalence was 22.1%, with Karongi having the highest at 10.7%. Factors associated with higher odds of high dietary diversity included the education of the household head (adjusted OR = 6.4, 95% CI: 1.05–39.7), age of women (adjusted OR = 3.03, 95% CI: 1.1–7.8), and wealth status (adjusted OR = 1.66, 95% CI: 0.51–5.4). Conversely, the occupation of women (adjusted OR = 0.13, 95% CI: 0.001–0.19), reading skills (adjusted OR = 0.27, 95% CI: 0.1–0.72), and family size (adjusted OR = 0.63, 95% CI: 0.35–1.1) were associated with lower odds of lower dietary diversity. Conclusion The findings highlight a significant nutritional challenge among Rwandan women, with low dietary diversity, significant rates of anemia, and food insecurity. The study calls for an urgent need for targeted nutritional interventions to improve dietary diversity and address micronutrient deficiencies among women in agriculture to enhance maternal health and child development, thereby contributing to broader public health goals.

Abstract Intensive care unit (ICU) mortality rates have decreased over time. However, in low-and lower-middle income countries (LMICs), there remains an excess ICU mortality with limited understanding of patient characteristics, treatments, and outcomes from small single centre studies. We aimed therefore, to describe the characteristics, therapies and outcomes of patients admitted to all intensive care units in Uganda. A nationwide prospective observational study including all patients admitted Uganda’s ICUs with available daily charts was conducted from 8th January 2018 to 1st April 2018. Socio-demographics and clinical characteristics including worst vital signs in the first 24 h of admission were recorded with calculation of the National Early Warning Score (NEWS-2) and quick Sequential Organ Function Assessment (qSOFA) score. ICU interventions were recorded during the ICU stay and patients were followed up to 28 days in ICU. The primary outcome was 28 day ICU mortality. Three-hundred fifty-one patients were analysed with mean age 39 (24.1) years, 205 (58.4%) males with 197 (56%) surgical admissions. The commonest indication for ICU admission was postoperative care (42.9%), 214 (61%) had at least one comorbidity, with hypertension 104 (48.6%) most prevalent and 35 (10%) HIV positive. The 28 day ICU mortality was 90/351 (25.6%) with a median ICU stay of 3 (1–7) days. The highest probability of death occurred during the first 10 days with more non-survivors receiving mechanical ventilation (80% vs 34%; p

Abstract Background Access to family planning services among young people is crucial for reproductive health. This study explores the access and associated factors among young people in Lira City, Northern Uganda. Methods and materials A mixed-methods study was conducted in March to April 2022. Quantitative data were collected using a structured questionnaire from 553 participants aged 15–24 years. Qualitative data were obtained through in-depth interviews and focus group discussions. Data analysis included univariate, bivariate, and multivariate analyses for quantitative data, while interpretative phenomenological analysis was used for qualitative data. Results Overall, 31.7% of the respondents had a good perceived access to family planning services, with 64.6% reporting perceived availability of FP methods. Challenges included lack of privacy (57.7%), fear of mistreatment (77.2%), and decision-making difficulties (66.2%). Among females, good perceived access to FP services was less likely among urban residents (AOR: 0.22, 95% CI: 0.09–0.53), Christian respondents (AOR: 0.51, 95% CI: 0.01–0.36), Muslim respondents (AOR: 0.07, 95% CI: 0.01–0.55) and respondents with poor attitude to FP services (AOR: 0.39, 95% CI: 0.24–0.64), but more likely among respondents with a sexual a partner (AOR: 4.48, 95% CI: 2.60–7.75). Among males, good perceived access to FP services was less likely among respondents living with parents (AOR: 0.19, 95% CI: 0.05–0.67) but more likely among respondents with good knowledge of FP services (AOR: 2.28, 95% CI: 1.02–5.32). Qualitative findings showed that three themes emerged; knowledge of family planning methods, beliefs about youth contraception and, friendliness of family planning services. Conclusion The study revealed a substantial gap in perceived access to family planning services among young people in Lira City. Barriers include privacy concerns, fear of mistreatment, and decision-making difficulties. Tailored interventions addressing urban access, religious beliefs for females, and knowledge enhancement for males are essential. Positive aspects like diverse FP methods and physical accessibility provide a foundation for targeted interventions. Youth-friendly services, comprehensive sexual education, and further research are emphasized for a nuanced understanding and effective interventions in Northern Uganda.

In high-income countries, outcomes following in hospital cardiac arrest have improved over the last two decades due to the introduction of rapid response teams, cardiac arrest teams, and advanced resuscitation training. However, in low-income countries, such as Rwanda, outcomes are still poor. This is due to multiple factors including lack of adequate resuscitation training, few trainers, and lack of equipment.To address this issue, the Initiative for Medical Equity and Global Health Equity (IMEGH), a training organization founded in 2018 by 5 local anesthesiologists has regularly taught resuscitation courses such as Basic Life Support, Advanced Cardiac Life Support, and Pediatric Advanced Life Support in hospitals throughout Rwanda. The aims of the organization include developing a sustainable model to offer context relevant resuscitation training courses, building a cadre of local instructors to teach on the courses, as well as engaging funding partners to help support the effort. From October 2018 until September 2022, 31 courses were run in 11 hospitals across Rwanda training 1,060 healthcare providers (mainly of non-physician anesthetists, nurses, midwives, and general practitioners). Ongoing challenges include lack of local protocols, inability to tracking resuscitation outcomes, and continued inaccessibility by many healthcare providers. Despite these challenges, the IMEGH program is an example of a successful context-relevant model and has potential to inform the design of resuscitation programs in other similar settings. This article describes the development of the IMEGH program, accomplishments as well as lessons learned, challenges, and next steps for expansion.

Rationale Acute hypoxaemic respiratory failure (AHRF) is associated with high mortality in sub-Saharan Africa. This is at least in part due to critical care-related resource constraints including limited access to invasive mechanical ventilation and/or highly skilled acute care workers. Continuous positive airway pressure (CPAP) and high-flow oxygen by nasal cannula (HFNC) may prove useful to reduce intubation, and therefore, improve survival outcomes among critically ill patients, particularly in resource-limited settings, but data in such settings are lacking. The aim of this study is to determine whether CPAP or HFNC as compared with standard oxygen therapy, could reduce mortality among adults presenting with AHRF in a resource-limited setting.Methods This is a prospective, multicentre, randomised, controlled, stepped wedge trial, in which patients presenting with AHRF in Uganda will be randomly assigned to standard oxygen therapy delivered through a face mask, HFNC oxygen or CPAP. The primary outcome is all-cause mortality at 28 days. Secondary outcomes include the number of patients with criteria for intubation at day 7, the number of patients intubated at day 28, ventilator-free days at day 28 and tolerance of each respiratory support.Ethics and dissemination The study has obtained ethical approval from the Research and Ethics Committee, School of Biomedical Sciences, College of Health Sciences, Makerere University as well as the Uganda National Council for Science and Technology. Patients will be included after informed consent. The results will be submitted for publication in peer-reviewed journals.Trial registration number NCT04693403.Protocol version 8 September 2023; version 5.

Background In Uganda where the burden of HIV-associated cryptococcal meningitis is high, conventional amphotericin B deoxycholate has been standard to manage patients with cryptococcal meningitis in research settings. However, liposomal amphotericin B (AmBisome) is now available via the efforts of UNITAID. We sought to describe our nursing experience using AmBisome within a clinical trial for cryptococcal meningitis. Methods We describe the experience of using single-dose 10mg/kg liposomal amphotericin B from the perspective of a research nurse in Uganda. Second, we described the process of preparing and administering amphotericin. Third, we assessed the nursing time required for the administration of daily amphotericin B versus single-dose liposomal amphotericin. Fourth, we discuss the major challenges faced while using liposomal amphotericin B. Results We provide estimates for the nursing time required for reconstituting, filtering, diluting and administering liposomal amphotericin B and a visual aid for nursing tasks. Based on five trained nurses, the process of reconstitution and filtration lasts an average of 52 minutes (Range: 40 to 60 minutes), to reconstitute a mean of 11 (range: 8 to 15) 50mg vials (median weight 55kg). Overall, less nursing time was required for single-dose administration than for daily amphotericin B dosing. From a nursing perspective, liposomal amphotericin B was preferable to amphotericin B deoxycholate due to its reduced infusion reactions and other toxicities. Conclusions Single-dose liposomal amphotericin B is a better alternative to daily amphotericin B. In addition to less toxicity, nosocomial infections, reduced hospital stay, and the potential for lower hospitalisation costs, the nursing implications should not be discounted. Quality nursing care is a finite resource in low- and middle-income countries, and single-dose amphotericin B reduced the nursing time required for the care of patients with cryptococcal meningitis.

The toxic effects of HAART affect the patients’ quality of life leading to poor adherence to their regimen. Therefore, the purpose of this study was to investigate the nephron-protective activity of methanol crude peel extract of Punica granatum (MPEPG) in HAART-administered Wistar rats.Methods: Thirty male albino Wistar rats weighing between 180– 200g were randomly divided into six groups of five rats each. Group one served as normal control and was given distilled water only. Group two serves as a negative control and was given HAART at a dosage of 64 mg/kg. Groups 3 and 4 were given 100 and 400 mg/kg of MPEPG, respectively, while groups 5 and 6 were given MPEPG dosages of 100 and 400 mg/kg along with HAART, respectively, for 40 days. The rats were sacrificed under halothane anaesthesia, and the kidneys were removed for histological evaluation, while blood samples were analyzed for biochemical parameters.Results: In the HAART (TLD) treated group, there was a significantly high amount of MDA and a lower level of the antioxidant enzymes SOD and CAT. Biochemical analysis revealed that animals treated with HAART (TLD) had significantly higher levels of urea and creatinine, which are biomarkers of kidney damage than the normal control animals. In contrast, all the kidney function markers were returned to normal levels in the HAART-treated group after administration of methanol crude peel extract of P. granatum. The kidney tissues of animals given HAART had considerable structural damage as revealed by histopathological studies. When HAART-exposed rats were treated with MPEPG, both the biochemical and histological results significantly improved.Conclusion: Methanol crude peel extract of P. granatum provided effective protection against kidney oxidative injury brought on by HAART because of its anti-oxidant and free radical scavenging properties.Keywords: HAART, oxidative stress, nephrotoxicity, Punica granatum

Introduction Trauma contributes to the greatest loss of disability-adjusted life-years for adolescents and young adults worldwide. In the context of global abdominal trauma, the trauma laparotomy is the most commonly performed operation. Variation likely exists in how these patients are managed and their subsequent outcomes, yet very little global data on the topic currently exists. The objective of the GOAL-Trauma study is to evaluate both patient and injury factors for those undergoing trauma laparotomy, their clinical management and postoperative outcomes.Methods We describe a planned prospective multicentre observational cohort study of patients undergoing trauma laparotomy. We will include patients of all ages who present to hospital with a blunt or penetrating injury and undergo a trauma laparotomy within 5 days of presentation to the treating centre. The study will collect system, patient, process and outcome data, following patients up until 30 days postoperatively (or until discharge or death, whichever is first). Our sample size calculation suggests we will need to recruit 552 patients from approximately 150 recruiting centres.Discussion The GOAL-Trauma study will provide a global snapshot of the current management and outcomes for patients undergoing a trauma laparotomy. It will also provide insight into the variation seen in the time delays for receiving care, the disease and patient factors present, and patient outcomes. For current standards of trauma care to be improved worldwide, a greater understanding of the current state of trauma laparotomy care is paramount if appropriate interventions and targets are to be identified and implemented.

BackgroundTo determine the pattern of immune cell subsets across the life span in rural sub-Saharan Africa (SSA), and to set a reference standard for cell subsets amongst Africans, we characterised the major immune cell subsets in peripheral blood including T cells, B cells, monocytes, NK cells, neutrophils and eosinophils, in individuals aged 3 to 89 years from Uganda.MethodsImmune phenotypes were measured using both conventional flow cytometry in 72 individuals, and full spectrum flow cytometry in 80 individuals. Epstein-Barr virus (EBV) IFN-γ T cell responses were quantified in 332 individuals using an ELISpot assay. Full blood counts of all study participants were also obtained.ResultsThe percentages of central memory (TCM) and senescent CD4+ and CD8+ T cell subsets, effector memory (TEM) CD8+ T cells and neutrophils increased with increasing age. On the other hand, the percentages of naïve T (TN) and B (BN) cells, atypical B cells (BA), total lymphocytes, eosinophils and basophils decreased with increasing age. There was no change in CD4+ or CD8+ T effector memory RA (TEMRA) cells, exhausted T cells, NK cells and monocytes with age. Higher eosinophil and basophil percentages were observed in males compared to females. T cell function as measured by IFN-γ responses to EBV increased with increasing age, peaking at 31-55 years.ConclusionThe percentages of cell subsets differ between individuals from SSA compared to those elsewhere, perhaps reflecting a different antigenic milieu. These results serve as a reference for normal values in this population.

Background: It is of utmost importance to monitor any change in the epidemiology of fungal diseases that may arise from a change in the number of the at-risk population or the availability of local data. Objective: We sought to update the 2015 publication on the incidence and prevalence of serious fungal diseases in Uganda. Methods: Using the Leading International Fungal Education methodology, we reviewed published data on fungal diseases and drivers of fungal diseases in Uganda. Regional or global data were used where there were no Ugandan data. Results: With a population of ~45 million, we estimate the annual burden of serious fungal diseases at 4,099,357 cases (about 9%). We estimated the burden of candidiasis as follows: recurrent Candida vaginitis (656,340 cases), oral candidiasis (29,057 cases), and esophageal candidiasis (74,686 cases) in HIV-infected people. Cryptococcal meningitis annual incidence is estimated at 5553 cases, Pneumocystis pneumonia at 4604 cases in adults and 2100 cases in children. For aspergillosis syndromes, invasive aspergillosis annual incidence (3607 cases), chronic pulmonary aspergillosis (26,765 annual cases and 63,574 5-year-period prevalent cases), and prevalence of allergic bronchopulmonary aspergillosis at 75,931 cases, and severe asthma with fungal sensitization at 100,228 cases. Tinea capitis is common with 3,047,989 prevalent cases. For other mycoses, we estimate the annual incidence of histoplasmosis to be 646 cases and mucormycosis at 9 cases. Conclusion: Serious fungal diseases affect nearly 9% of Ugandans every year. Tuberculosis and HIV remain the most important predisposition to acute fungal infection necessitating accelerated preventive, diagnostic, and therapeutic interventions for the management of these diseases.

Abstract Background Diabetes mellitus is a complex heterogeneous metabolic disorder known to lead to several pathogenic disorders, and has a bidirectional relationship with oral health conditions. This study aimed at estimating the prevalence, treatment needs and correlates of dental caries among adult patients attending a diabetic clinic in Uganda. Methods This was a cross-sectional study that used questionnaires to collect data on socio-demographic factors, diabetes history, oral health status, dental health care, dietary factors, lifestyle factors, and dental examination guided by the modified World Health Organization oral health questionnaire for adults. Results We enrolled 239 participants, prevalence of dental caries was 71.6%, treatment need was nearly 100%, and mean DMFT was 3.82 (SD = 5.46). Dental caries experience was associated with being widowed. Conclusion We found a high prevalence of dental caries experience and large treatment need among our participants. We recommend integration of oral health care into routine diabetic services in rural sub Saharan Africa.

Background Improved access to healthcare in low- and middle-income countries (LMICs) has not equated to improved health outcomes. Absence or unsustained quality of care is partly to blame. Improving outcomes in intensive care units (ICUs) requires delivery of complex interventions by multiple specialties working in concert, and the simultaneous prevention of avoidable harms associated with the illness and the treatment interventions. Therefore, successful design and implementation of improvement interventions requires understanding of the behavioural, organisational, and external factors that determine care delivery and the likelihood of achieving sustained improvement. We aim to identify care processes that contribute to suboptimal clinical outcomes in ICUs located in LMICs and to establish barriers and enablers for improving the care processes. Methods Using rapid evaluation methods, we will use four data collection methods: 1) registry embedded indicators to assess quality of care processes and their associated outcomes; 2) process mapping to provide a preliminary framework to understand gaps between current and desired care practices; 3) structured observations of processes of interest identified from the process mapping and; 4) focus group discussions with stakeholders to identify barriers and enablers influencing the gap between current and desired care practices. We will also collect self-assessments of readiness for quality improvement. Data collection and analysis will be led by local stakeholders, performed in parallel and through an iterative process across eight countries: Kenya, India, Malaysia, Nepal, Pakistan, South Africa, Uganda and Vietnam. Conclusions The results of our study will provide essential information on where and how care processes can be improved to facilitate better quality of care to critically ill patients in LMICs; thus, reduce preventable mortality and morbidity in ICUs. Furthermore, understanding the rapid evaluation methods that will be used for this study will allow other researchers and healthcare professionals to carry out similar research in ICUs and other health services.

ObjectiveSub-Saharan Africa faces twin epidemics of HIV and noncommunicable diseases including hypertension. Integrating hypertension care into chronic HIV care is a global priority, but cost estimates are lacking. In the SEARCH Study, we performed population-level HIV/hypertension testing, and offered integrated streamlined chronic care. Here, we estimate costs for integrated hypertension/HIV care for HIV-positive individuals, and costs for hypertension care for HIV-negative individuals in the same clinics.DesignMicrocosting analysis of healthcare expenditures within Ugandan HIV clinics.MethodsSEARCH (NCT: 01864603) conducted community health campaigns for diagnosis and linkage to care for both HIV and hypertension. HIV-positive patients received hypertension/HIV care jointly including blood pressure monitoring and medications; HIV-negative patients received hypertension care at the same clinics. Within 10 Ugandan study communities during 2015-2016, we estimated incremental annual per-patient hypertension care costs using micro-costing techniques, time-and-motion personnel studies, and administrative/clinical records review.ResultsOverall, 70 HIV-positive and 2355 HIV-negative participants received hypertension care. For HIV-positive participants, average incremental cost of hypertension care was $6.29 per person per year, a 2.1% marginal increase over prior estimates for HIV care alone. For HIV-negative participants, hypertension care cost $11.39 per person per year, a 3.8% marginal increase over HIV care costs. Key costs for HIV-positive patients included hypertension medications ($6.19 per patient per year; 98% of total) and laboratory testing ($0.10 per patient per year; 2%). Key costs for HIV-negative patients included medications ($5.09 per patient per year; 45%) and clinic staff salaries ($3.66 per patient per year; 32%).ConclusionFor only 2-4% estimated additional costs, hypertension care was added to HIV care, and also expanded to all HIV-negative patients in prototypic Ugandan clinics, demonstrating substantial synergy. Our results should encourage accelerated scale-up of hypertension care into existing clinics.

Scaphoid, the boat-shaped carpal bone, is largely covered by articular cartilage. It has a much more complex arterial supply than previously reported, moreover, this arterial pattern has been hypothesized to lead to avascular necrosis after fractures Scaphoid blood supply has long been documented as scarce; it arises from the radial artery giving palmar and dorsal branches. There is high-grade evidence reporting two main arteries entering from the distal half of the scaphoid and middle to lower-grade evidence reporting several arteries scattered over the entire scaphoid and anastomosis of the radial artery with intercarpal arteries. Dorsal arteries are slightly larger in diameter and many more than volar ones. The scaphoid shape is associated with variations in arterial supply patterns. Scaphoid surgery preserving vascular supply is the gold standard. Scaphoid blood supply is not as poor as previously documented, as current evidence supports even proximal pole vascularization. We recommend surgery to preserve the blood supply and foster research in this area.

Introduction: The World Health Organization acknowledges the need for countries to incorporate neglected tropical disease care into their routine health care system. However, low detection rates and late presentation of mycetoma to health facilities have been observed in endemic countries, including Uganda. Objective: To empower community health workers (CHWs) in Northern Uganda to recognize and refer suspects of mycetoma to health facilities. Design: This will be a stepped-wedge cluster-randomized trial based in Gulu and Pader districts over a period of 9 months with sequential crossover from intervention phase to the control phase at different time points until both districts are exposed to the intervention. Methods and Analysis: The study will leverage on the ongoing partnership between Northern Uganda Medical Mission and the Uganda Ministry of Health that has trained over 300 CHWs in Gulu and Pader. The study evaluation will be done using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework. The expected outcome of the study is increased detection and referral of suspects of mycetoma. Data will be analyzed using STATA 17.0 and Friedman statistics or Analysis of Variance to determine increase in case identifications and referrals. Ethics and Registration: The study was approved by Mulago Hospital Research and Ethics Committee (MHREC 2406) and registered with Pan African Clinical Trial Registry (PACTR202301534749787). Dissemination: The results from this trial will be published in a peer-reviewed journal. In addition, the findings will be shared at conferences, with funders, and at other research meetings.

Background: This study assessed the potential cost-effectiveness of high (80–100%) vs low (21–35%) fraction of inspired oxygen (FiO2) at preventing surgical site infections (SSIs) after abdominal surgery in Nigeria, India, and South Africa. Methods: Decision-analytic models were constructed using best available evidence sourced from unbundled data of an ongoing pilot trial assessing the effectiveness of high FiO2, published literature, and a cost survey in Nigeria, India, and South Africa. Effectiveness was measured as percentage of SSIs at 30 days after surgery, a healthcare perspective was adopted, and costs were reported in US dollars ($). Results: High FiO2 may be cost-effective (cheaper and effective). In Nigeria, the average cost for high FiO2 was $216 compared with $222 for low FiO2 leading to a −$6 (95% confidence interval [CI]: −$13 to −$1) difference in costs. In India, the average cost for high FiO2 was $184 compared with $195 for low FiO2 leading to a −$11 (95% CI: −$15 to −$6) difference in costs. In South Africa, the average cost for high FiO2 was $1164 compared with $1257 for low FiO2 leading to a −$93 (95% CI: −$132 to −$65) difference in costs. The high FiO2 arm had few SSIs, 7.33% compared with 8.38% for low FiO2, leading to a −1.05 (95% CI: −1.14 to −0.90) percentage point reduction in SSIs. Conclusion: High FiO2 could be cost-effective at preventing SSIs in the three countries but further data from large clinical trials are required to confirm this.

Introduction: The influence of non-technical skills training on resuscitation performance in low-resource settings is unknown. This study investigates combining the Vital Anaesthesia Simulation Training Course with Advanced Cardiac Life Support training on resuscitation performance in Rwanda. Methods: Participants in this mixed method study are members of resuscitation teams in three district hospitals in Rwanda. The intervention was participation in a 2-day Advanced Cardiac Life Support course followed by the 3-day Vital Anaesthesia Simulation Training Course. Quantitative primary endpoints were time to initiation of cardiopulmonary resuscitation, time to epinephrine administration, and time to defibrillation. Qualitative data on workplace implementation were gathered during focus groups held 3-months post-intervention. Results: Forty-seven participants were recruited. Quantitative data showed a statistically significant decrease in time to cardiopulmonary resuscitation, epinephrine administration, and defibrillation from pre- to post-Advanced Cardiac Life Support, with times of [43.3 (49.7) seconds] versus [16.5 (20) sec], p =

BackgroundFungal-bacterial cocolonization and coinfections pose an emerging challenge among patients suspected of having pulmonary tuberculosis (PTB); however, the underlying pathogenic mechanisms and microbiome interactions are poorly understood. Understanding how environmental microbes, such as fungi and bacteria, coevolve and develop traits to evade host immune responses and resist treatment is critical to controlling opportunistic pulmonary fungal coinfections. In this project, we propose to study the coexistence of fungal and bacterial microbial communities during chronic pulmonary diseases, with a keen interest in underpinning fungal etiological evolution and the predominating interactions that may exist between fungi and bacteria. ObjectiveThis is a protocol for a study aimed at investigating the metabolic and molecular ecological evolution of opportunistic pulmonary fungal coinfections through determining and characterizing the burden, etiological profiles, microbial communities, and interactions established between fungi and bacteria as implicated among patients with presumptive PTB. MethodsThis will be a laboratory-based cross-sectional study, with a sample size of 406 participants. From each participant, 2 sputa samples (one on-spot and one early morning) will be collected. These samples will then be analyzed for both fungal and bacterial etiology using conventional metabolic and molecular (intergenic transcribed spacer and 16S ribosomal DNA–based polymerase chain reaction) approaches. We will also attempt to design a genome-scale metabolic model for pulmonary microbial communities to analyze the composition of the entire microbiome (ie, fungi and bacteria) and investigate host-microbial interactions under different patient conditions. This analysis will be based on the interplays of genes (identified by metagenomics) and inferred from amplicon data and metabolites (identified by metabolomics) by analyzing the full data set and using specific computational tools. We will also collect baseline data, including demographic and clinical history, using a patient-reported questionnaire. Altogether, this approach will contribute to a diagnostic-based observational study. The primary outcome will be the overall fungal and bacterial diagnostic profile of the study participants. Other diagnostic factors associated with the etiological profile, such as incidence and prevalence, will also be analyzed using univariate and multivariate schemes. Odds ratios with 95% CIs will be presented with a statistical significance set at P

Introduction SARS-CoV-2 has been identified as the cause of the disease officially named COVID-19, primarily a respiratory illness. COVID-19 was characterised as a pandemic on 11 March 2020. It has been estimated that approximately 20% of people with COVID-19 require oxygen therapy. Oxygen has been listed on the WHO Model List of Essential Medicines List and Essential Medicines List for Children for almost two decades. The COVID-19 pandemic has highlighted, more than ever, the acute need for scale-up of oxygen therapy. Detailed data on the use of oxygen therapy in low-and-middle income countries at the patient and facility level are needed to target interventions better globally.Methods and analysis We aim to describe the requirements and use of oxygen at the facility and patient level of approximately 4500 patients with COVID-19 in 30 countries. Our objectives are specifically to characterise type and duration of different modalities of oxygen therapy delivered to patients; describe demographics and outcomes of hospitalised patients with COVID-19; and describe facility-level oxygen production and support. Primary analyses will be descriptive in nature. Respiratory support transitions will be described in Sankey plots, and Kaplan-Meier models will be used to estimate probability of each transition. A multistate model will be used to study the course of hospital stay of the study population, evaluating transitions of escalating respiratory support transitions to the absorbing states.Ethics and dissemination WHO Ad Hoc COVID-19 Research Ethics Review Committee (ERC) has approved this global protocol. When this protocol is adopted at specific country sites, national ERCs may make require adjustments in accordance with their respective national research ethics guidelines. Dissemination of this protocol and global findings will be open access through peer-reviewed scientific journals, study website, press and online media.Trial registration number NCT04918875.
