(Tropical medicine and health, 2021) Kanyike, Andrew Marvin; Olum, Ronald; Kajjimu, Jonathan; Ojilong, Daniel; Madut Akech, Gabriel; Nassozi, Dianah Rhoda; Agira, Drake; Kisaakye Wamala, Nicholas; Asiimwe, Asaph; Matovu, Dissan; Nakimuli, Ann Babra; Lyavala, Musilim; Kulwenza, Patricia; Kiwumulo, Joshua; Bongomin, Felix
COVID-19 is still a major global threat for which vaccination remains the ultimate solution. Uganda reported 40,751 cases and 335 deaths as of 9 April 2021 and started its vaccination program among priority groups like health workers, teachers, those with chronic diseases among others in early March 2021. Unanimous uptake of the COVID-19 vaccine is required to subsequently avert its spread; therefore, we assessed COVID-19 vaccine acceptability, hesitancy, and associated factors among medical students in Uganda. Methods: This study employed an online descriptive cross-sectional survey among medical students across 10 medical schools in Uganda. A structured questionnaire via Google Form was conveniently sent to eligible participants via WhatsApp. Each medical school had a coordinator who consistently shared the data tool in the WhatsApp groups. Chi-square or Fisher’s exact test, and logistic regression were used to assess the association between vaccine acceptability with demographics, COVID-19 risk perception, and vaccine hesitancy. Results: We surveyed 600 medical students, 377 (62.8%) were male. COVID-19 vaccine acceptability was 37.3% and vaccine hesitancy 30.7%. Factors associated with vaccine acceptability were being male (adjusted odds ratio (aOR) = 1.9, 95% CI 1.3–2.9, p=0.001) and being single (aOR= 2.1, 95% CI 1.1–3.9, p=0.022). Very high (aOR= 3.5, 95% CI 1.7– 6.9, p<0.001) or moderate (aOR =2.2, 95% CI 1.2–4.1, p=0.008) perceived risk of getting COVID-19 in the future, receiving any vaccine in the past 5 years (aOR= 1.6, 95% CI 1.1–2.5, p=0.017), and COVID-19 vaccine hesitancy (aOR 0.6, 95% CI 0.4–0.9, p=0.036). Conclusions: This study revealed low levels of acceptance towards the COVID-19 vaccine among medical students, low self-perceived risks of COVID-19, and many had relied on social media that provided them with negative information. This poses an evident risk on the battle towards COVID-19 in the future especially when these future health professions are expected to be influencing decisions of the general public towards the same.
Anemia in Diabetes Mellitus in Africa: A Systematic Review and Meta-analysis
(Clinical Research & Reviews, 2021) Olum, Ronald; Bongomin, Felix; Kaggwa, Mark Mohan; Andia-Biraro, Irene; Baluku, Joseph Baruch
Anemia accelerates chronic complications of diabetes mellitus (DM). We aimed to conduct a systematic review and meta-analysis to estimate the prevalence of anemia among people with DM in Africa.A search of studies was conducted in the main databases (Medline, EMBASE, Scopus, CINAHL, AJOL and Google Scholar) and the reference lists of selected studies. Observational studies that met the eligibility criteria were included in this meta-analysis. There was no limitation in terms of language.We obtained data from 27 eligible studies, including 5913 patients. The pooled prevalence of anemia was 35% (95% CI: 28%–42%, I2 = 97.7%, p < 0.01). In sub-group analysis, the pooled prevalence was higher in people with diabetic foot lesions (56%, 95% CI: 49%–63%, I2 = 51.04%, p = 0.100) than in the general population of people with diabetes (30%, 95% CI: 23%–37%, I2 = 97.6%, p < 0.01). Pooled prevalence rates were also higher in; males than females (34% vs 31%), type II DM than type I DM (35% vs 26%), and in patients with poor glycemic control compared to those with good glycemic control (33% vs. 22%).The prevalence of anemia in DM was high warranting enhanced clinical and public health interventions.
Anemia in Ugandan pregnant women: a cross-sectional, systematic review and meta-analysis study
(Tropical medicine and health, 2021) Bongomin, Felix; Olum, Ronald; Kyazze, Andrew Peter; Ninsiima, Sandra; Nattabi, Gloria; Nakyagaba, Lourita; Nabakka, Winnie; Kukunda, Rebecca; Ssekamatte, Phillip; Kibirige, Davis; Cose, Stephen; Nakimuli, Annettee
Anemia in pregnancy represents a global public health concern due to wide ranging maternal and neonatal adverse outcomes in all peripartum periods. We estimated the prevalence and factors associated with anemia in pregnancy at a national obstetrics and gynecology referral hospital in Uganda and in addition performed a systematic review and meta-analysis of the overall burden of anemia in pregnancy in Uganda. Methods: We conducted a cross-sectional study among 263 pregnant women attending the antenatal care clinic of Kawempe National Referral Hospital, Kampala, Uganda, in September 2020. Anemia in pregnancy was defined as a hemoglobin level of < 11.0 g/dl and microcytosis as a mean corpuscular volume (MCV) of < 76 fL. We also performed a systematic review (PROSPERO Registration ID: CRD42020213001) and meta-analysis of studies indexed on MEDLINE, Embase, African Journal Online, ClinicalTrials.gov, ICTRP, and the Cochrane Library of systematic review between 1 January 2000 and 31 September 2020 reporting on the prevalence of anemia in pregnancy in Uganda. Results: The prevalence of anemia was 14.1% (n= 37) (95%CI 10.4–18.8), of whom 21 (56.8%) had microcytic anemia. All cases of anemia occurred in the second or third trimester of pregnancy and none were severe. However, women with anemia had significantly lower MCV (75.1 vs. 80.2 fL, p<0.0001) and anthropometric measurements, such as weight (63.3 vs. 68.9kg; p=0.008), body mass index (25.2 vs. 27.3, p=0.013), hip (98.5 vs. 103.8 cm, p=0.002), and waist (91.1 vs. 95.1 cm, p=0.027) circumferences and mean systolic blood pressure (BP) (118 vs 125 mmHg, p=0.014). Additionally, most had BP within the normal range (59.5% vs. 34.1%, p=0.023). The comparison meta-analysis of pooled data from 17 published studies of anemia in pregnancy in Uganda, which had a total of 14,410 pregnant mothers, revealed a prevalence of 30% (95% CI 23–37). Conclusions: Despite our study having a lower prevalence compared to other studies in Uganda, these findings further confirm that anemia in pregnancy is still of public health significance and is likely to have nutritional causes, requiring targeted interventions. A larger study would be necessary to demonstrate potential use of basic clinical parameters such as weight or blood pressure as screening predictors for anemia in pregnancy.
Antibiotic Practices, Perceptions and Self-Medication Among Patients at a National Referral Hospital in Uganda
(Infection and drug resistance, 2021) Nabaweesi, Irene; Olum, Ronald; Sekite, Arthur Brian; Tumwesigye Suubi, Willy; Nakiwunga, Prossy; Machali, Aron; Kiyumba, Richard; Kalyango, Peter; Natamba, Allen; Igumba, Yokosofati; Kyeyune, Martin; Mpairwe, Harriet; Katagirya, Eric
Antimicrobial resistance (AMR) is a major global health concern with increasing reports of microorganisms resistant to most of the available antibiotics. There are limited data on antibiotic practices, perceptions and self-medication among Ugandans, necessitating this study. Methods: A cross-sectional study was conducted among patients at Kiruddu National Referral Hospital, Kampala, Uganda. A pre-tested interviewer administered a questionnaire that was used to collect data after an informed consent. Chi-square tests and logistic regression were used to assess associations between outcome and exposure variables. A P<0.05 was statistically significant. Results: A total of 279 patients (response rate=71%) with a median age of 32 years participated in the study. The majority were females (55.6%, n=155) and from the outpatient department (74.9%, n=209). Overall, 212 (76%) participants had taken an antibiotic in the past 6 months, and some 22.2% (n=47) of the participants had practiced self-medication. Male participants (adjusted odds ratio (aOR)=2.13, 95% confidence intervals (CI): 1.01 to 4.50, P=0.046) and Muslims (aOR=4.37, 96% CI:1.54 to 12.44, P=0.006) were more likely to self-medicate. Employees (aOR=0.06, 95% CI:0.01 to 0.51, P=0.010) and patients with tertiary education (aOR=0.14, 95% CI: 0.02 to 0.81, P=0.028) were less likely to practice self-medication. About 33% (n=70) of the participants had not completed treatment dosage during their last course of antibiotic treatment because of feeling better (60%, n=42), lack of money to purchase the medication (15.7%, n=11) and side effects (10%, n=7). Whereas 169 participants (79.7%) believed that not completing treatment would have an impact on their personal health, only 96 participants (45.3%) believed that this behaviour could affect the health of others. Conclusion: Antibiotic misuse is significant among patients in Uganda. Continuous health education programs aimed at informing the public on antimicrobial resistance, and its dangers are recommended to curtail this challenge.
Antimicrobial resistance and rational use of medicine: knowledge, perceptions, and training of clinical health professions students in Uganda
(Research Square, 2022) Kanyike, Andrew Marvin; Olum, Ronald; Kajjimu, Jonathan; Owembabazi, Shebah; Ojilong, Daniel; Nassozi, Dianah Rhoda; Amongin, Joan Fidelia; Atulinda, Linda; Agaba, Kenneth; Buule, Richard; Nabukeera, Germinah; Kyomuhendo, Robert; Luwano, Rehema; Owobusingye, Whitney; Matovu, Dissan; Musoke, Philip; Bongomin, Felix; Kiyimba, Kenedy
Antimicrobial resistance (AMR) is an important global health concern, projected to contribute to significant mortality, particularly in developing countries. This study aimed to determine the knowledge, perceptions of clinical health professions students towards antimicrobial resistance and rational use of medicine and confidence level to prescribe antimicrobials. Methods: An online descriptive cross-sectional survey was conducted among clinical health professions students across 9 medical schools in Uganda. A semi-structured questionnaire using Kobo Toolbox form was shared among participants via WhatsApp Messenger (Meta, California, USA). Knowledge was categorized using modified Bloom’s cut-off. One-way ANOVA, Chi-square or Fisher’s exact test, and logistic regression were used to assess the association between dependent and independent variables. A p<0.05 was considered statistically significant. Results: We surveyed 681 participants, most were pursuing a Bachelor of Medicine and Surgery degree (n=433, 63.6%), with a mean age of 24 (standard deviation: 3.6) years. Most participants (n=596, 87.5%) had sufficient knowledge about antimicrobial resistance with a mean score of 85 ± 14.2%. There was a significant difference in mean knowledge scores of year 4 (86.6%) compared to year 3 (82.4%) (p=0.002) and year 5 (88.0%) compared to year 3 (82.4%) (p<0.001). Most participants (n=456, 66.9%), were confident on making an accurate diagnosis of infection, and choosing the correct antimicrobial agent to use (n=484, 71.1%). Conclusion: Health profession students exhibited good knowledge on antimicrobial resistance and high self-perceived confidence on antimicrobial prescriptions however they still agreed that a separated course unit on AMR is necessary.
Assessing Knowledge, Attitudes and Practices Towards COVID-19 Public Health Preventive Measures Among Patients at Mulago National Referral Hospital
(Risk management and healthcare policy, 2021) Twinamasiko, Nelson; Olum, Ronald; Gwokyalya, Anna Maria; Nakityo, Innocent; Wasswa, Enock; Sserunjogi, Emmanuel
COVID-19 has become a major global health challenge, with Uganda reporting over 20,000 cases. There is, however, a scarcity of data on the perception of patients in Uganda towards the highly infectious disease. We aimed to assess the awareness, knowledge, attitudes, and practices towards COVID-19 preventive measures among patients at Mulago National Referral Hospital (MNRH), Uganda. Methods: A cross-sectional quantitative survey was conducted in August, 2020, among patients in surgical and medical wards at MNRH. An interviewer-administered, pre-validated questionnaire was used to collect data that was entered into Google Forms and analyzed using Microsoft Excel and STATA 16. Descriptive statistics was used to present data from univariate analysis. Patients whose knowledge and practice scores were greater or equal to the average score were regarded to have good knowledge and practices respectively. Chisquare, Fisher’s Exact tests and binary logistic regression were used to assess factors associated with COVID-19 knowledge and practices. A P<0.05 was statistically significant. Results: Overall, 114 patients were approached and 102 consented to participate. Most were females (53.8%), aged above 45 years (31.4%) with 40.2% reporting primary level as the highest level of education. About 55.9% (n=57) had adequate knowledge for COVID-19 and its related practices, and 52% (n=53) had good COVID-19 related practices. Knowledge significantly differed by marital status at bivariate analysis (P=0.020), however this lost significance at logistic regression. Female patients were thrice more likely to have good COVID-19 prevention practices compared to males (COR: 2.59, 95% CI: 1.2 to 5.8, P=0.020). Some 47 (46.1%) participants perceived that COVID-19 preventive measures were not difficult at all to observe. Conclusion: About half of the patients at Mulago National Referral Hospital lack adequate knowledge and practice on COVID-19 prevention. Continued patient education is required to increase knowledge which will in turn improve adherence to COVID-19 preventive practices.
Assessment of knowledge, attitude and practice of first aid among taxi operators in a Kampala City Taxi Park, Uganda: A cross-sectional study
(African journal of emergency medicine, 2022) Ssewante, Nelson; Wekha, Godfrey; Namusoke, Moureen; Sanyu, Bereta; Nkwanga, Ayub; Nalunkuma, Racheal; Olum, Ronald; Katumba Ssentongo, Lawrence; Ahabwe, Rachel; Kalembe, Sharon Esther; Nalwoga Nantagya, Vanessa; Kalanzi, Joseph
Road traffic accidents are among the leading causes of death in Uganda. Taxi operators are at a high risk of RTA and can potentially be first responders. This study, aimed to assess knowledge, attitude, and practice of first aid among taxi operators in the new taxi park, Kampala Uganda. Methods: A descriptive cross-sectional study was conducted in 2021 among taxi drivers and conductors in the New Taxi Park, Kampala City, Uganda. A semi-structured questionnaire was used to collect quantitative data from taxi operators after informed consent. Chi-square or Fisher’s exact test and logistic regression were performed in STATA 16 to assess the association between first aid knowledge and demographics. P < 0.05 was statistically significant. Results: A total of 345 participants, majority males (n = 338, 98%) aged between 18 and 45 years (76.5%), were recruited. Although 97.7% (n = 337) had heard about first aid, only 19.4% (n = 67) had prior first aid training. Overall mean knowledge score was 40.1% (SD = 14.5%), with 29.9% (n = 103) having good knowledge (≥50%). Participants who had witnessed more than five accidents (aOR = 2.9, 95% CI = 1.7–4.8, p < 0.001), those with first aid kits (aOR = 1.7, 95% CI = 1.0–3.0, p = 0.38) were more likely to have good knowledge while those below post-secondary education level i.e., Primary (AOR = 0.2, 95% CI = 0.1–0.5, p ≤0.001) and secondary (aOR = 0.2, 95% CI = 0.1–0.6, p = 0.001), were less likely to have good knowledge. About 97% and 93% perceived first aid as important and were willing to undergo training, respectively; however, only 69% were willing to give first aid. Only 181(52.5%) had ever attended to accident victims. Conclusion: Majority of taxi operators had poor first aid knowledge. Factors associated with good knowledge included level of education, number of accidents witnessed, having first aid kits. Although their attitudes were favorable, practice was poor. Comprehensive training and refresher courses can help increase first aid knowledge, and improving practice.

(Research Square, 2021) Batte, Charles; Semulimi, Andrew Weil; Kasoma Mutebi, Ronald; Mukisa, John; Olum, Ronald; Bongomin, Felix
The coronavirus disease – 2019 (COVID-19) pandemic has caused devastating effects across all sectors. The closure of schools negatively affected school going children globally. The present study sought to assess the effect of the ongoing COVID-19 pandemic and measures put in place to curb its spread on the psychosocial wellbeing of school going children in Bududa District, in Uganda. Methods: This was a cross-sectional study in which randomly enrolled school-going children from three conveniently selected sub-counties, Bukalasi, Bushiyi, and Bushika, in Bududa District, Uganda. Pretested standardised semi-structured questionnaires were used to collect data on the impact of COVID-19 pandemic on education and psychosocial status of the participants. Results: A total of 210 participants were studied. Of this, 122 (53.3%) were male, 203 (96.7%) lived in rural settings, and 155 (73.8%) were staying with both parents. The median age of the participants was 12 (interquartile range: 9 -15) years. One hundred ninety one (90.9%) participants were in primary school. Overall, 154 (73.3%) were worried about not going back to school during the lock down, however, 109 (51.9%) were able to return to school after the easing of the lockdown. Eighty-five (40.5%) participants received reading material at home during lockdown with 64 (30.5%) of the participants accessing teachings through radio. Of the 210 participants, 174 (82.9%) felt worried about the future, 172 (81.9%) felt like they were going to die during lockdown, 141 (67.1%) felt lonely at times, and 129 (61.4%) felt sad or low sometimes during the COVID-19 pandemic. A quarter (54) of 210 participants faced abuse of which 42 (77.8%) faced physical abuse from parents. Of 31 participants who sought help, 19 (61.3%) went to their parents with none getting help from non-governmental organisations. Fifty (23.8%) participants were engaged in work; 33 (66%) were paid, 4 (8%) were forced to work, and 22 (44%) faced physical challenges at their jobs. Conclusion: There was a substantial impact of the COVID-19 pandemic on the education and psychosocial wellbeing of school-going children in Bududa District. A comprehensive child psychological support service should be scaled up to provide support to school going children in vulnerable communities.
Assessment of the Knowledge and Attitude Towards Dementia Among Undergraduate University Students in Uganda
(Advances in Medical Education and Practice, 2021) Musoke, Phillip; Olum, Ronald; Kembabazi, Shallon; Nantaayi, Brandy; Bongomin, Felix; Kaddumukasa, Mark
Dementia remains a public health concern and a leading cause of disability and dependency among older people worldwide. However, the knowledge and attitudes towards dementia among university students remain unknown. This study assessed the knowledge and attitude towards dementia among university students in Uganda.An online descriptive, cross-sectional study was undertaken from August to November 2020, among undergraduate students from 11 Ugandan universities. A validated study questionnaire was used to collect data on socio-demographic characteristics, knowledge, and attitudes of dementia. A score <60% was considered poor knowledge while ≥80% good knowledge and more than 80% reflected positive attitudes.Overall, 1005 participants with a median age of 23 (interquartile range: 18 to 35) years participated in the study. The majority of the students were male (56.5%, n=568) and nearly half were pursuing human sciences/medicine-related programs. The mean knowledge score was 65.5% (SD±18.5). Thirty-two percent of the study participants had poor knowledge and only 26.8% (n=269) had good knowledge of dementia. More than half of the study participants believed that dementia is a normal part of aging and that memory loss happens to all people as they age. Attitudes towards patients with dementia were positive with a mean score of 81.9% (SD±19.6) and 65.2% of the study participants had positive dementia attitudes. Those aged more than 24 years were significantly associated with positive attitudes (adjusted odds ratio (AOR): 1.5, 95% CI: 1.1–2.0, p=0.019). There was a weak correlation between knowledge and attitude scores (ρ=0.341, p<0.001). Whereas the majority of university students have positive attitudes towards patients with dementia, a significant number still have poor knowledge of the same. Continuous health education is suggested to improve knowledge of dementia in this population. Further studies to understand the perception in the general population are recommended.
Association of circulating serum free bioavailable and total vitamin D with cathelicidin levels among active TB patients and household contacts
(Research Square, 2022) Acen, Ester Lilian; Worodria, William; Kateete, David Patrick; Olum, Ronald; Joloba, Moses L.; Akintola, Ashraf; Bbuye, Mudarshiru; Biraro Andia, Irene
The free hormone hypothesis postulates that the estimation of free circulating 25(OH)D may be a better marker of vitamin D status and is of clinical importance compared to total vitamin D levels because it is the fraction involved in biological activities. Studies have shown that cathelicidin inhibits the growth of Mycobacterium Tuberculosis in a vitamin D-dependent manner and therefore adequate vitamin D is required for its expression. The aim of the study was to determine the association between serum-free and bioavailable and total vitamin D with LL-37 levels in ATB patients, LTBI and individuals with no TB infection. This was a cross sectional study and free and bioavailable vitamin D and LL-37 levels were measured. 95 specimens were further selected to estimate total vitamin D levels. The median free and bioavailable vitamin D levels of study participants were 3.8 ng/mL. The median LL-37 levels were 318.8 ng/mL. The mean total vitamin D levels were 18.9 ng/mL. Significantly weak inverse associations were found and vitamin D is involved in the regulation of LL-37 expression and low vitamin D levels can alter this relationship. Background Vitamin D deficiency is a prominent risk factor for TB disease worldwide (1–5). Vitamin D can be obtained in two forms, D2 is obtained through diet and D3 is obtained through skin biosynthesis (6). Its main circulating active metabolite 1, 25(OH)D is involved in regulation of antimicrobial activity and therefore important in TB therapy (7). So far, total vitamin D or 25(OH)D has been considered a better index for determining vitamin D status due to its longer half-life (6, 8–11). However, the free hormone hypothesis postulates that the estimation of free circulating 25(OH)D may be a better marker of vitamin D status and is of clinical importance compared to total vitamin D levels because it is the fraction involved in biological activities (10, 12–14). Bioavailable 25(OH)D is used to represent free vitamin D and the 10–15% fraction is loosely bound to albumin (8, 15). About 85–90% of total 25(OH)D is bound to VDBP and 10–15% is loosely bound to albumin and a small fraction remains unbound (13, 16). Free 25(OH)D is increased and readily available to cells when DBP levels are at low concentrations Previous studies report that changes in DBP levels and 25(OH)D binding affinity can lead to higher levels of free 25(OH)D, even in the absence of total vitamin D levels (17, 18). According to the Endocrine Society, total vitamin D status is classified into three groups: <20 ng/mL deficient, 21–29 ng/mL deficient, and > 30 ng/mL optimal; or sufficient amounts (19). In vitro and in vivo studies have shown that LL-37 inhibits the growth of MTB in a vitamin D-dependent manner (20, 21). Accordingly, studies have reported that adequate levels of 25(OH)D are required for expression of LL-37(22, 23). According to our systematic review, six studies reported that vitamin D regulates LL-37 expression and that vitamin D deficiency alters this function (24). Because the free fraction of vitamin D, which enters cells to cause biological effects, has not been studied with the LL-37 molecule, we hypothesize that there is no relationship between free and bioavailable vitamin D and total vitamin D with the LL-37 levels among the ATB patients, LTBI and individuals with no TB infection. This study aimed to determine the association between serum-free and bioavailable and total vitamin D with LL-37 levels in ATB patients, LTBI and individuals with no TB infection.
Availability and affordability of essential medicines and diagnostic tests for diabetes mellitus in Africa
(Tropical Medicine & International Health, 2022) Kibirige, Davis; Olum, Ronald; Kyazze, Andrew Peter; Bongomin, Felix; Sanya, Richard E.
To investigate the current status of the availability and affordability of specific essential medicines and diagnostics for diabetes in Africa. Methods: Systematic review and meta-analysis. Studies conducted in Africa that reported any information on the availability and affordability of short-acting, intermediate-acting, and premixed insulin, glibenclamide, metformin, blood glucose, glycated haemoglobin or HbA1c, and lipid profile tests were included. Random-effect model metaanalysis and descriptive statistics were performed to determine the pooled availability and affordability, respectively. Results: A total of 21 studies were included. The pooled availability of each drug was as follows: short-acting insulin 33.5% (95% CI: 17.8% - 49.2%, I2=95.02%), intermediate-acting insulin 23.1% (95% CI: 6.3% - 39.9%, I2=91.6%), premixed insulin 49.4% (95% CI: 24.9% - 73.9%, I2=90.57%), glibenclamide 55.9% (95% CI: 43.8% - 68.0%, I2=96.7%), and metformin 47.0% (95% CI: 34.6% - 59.4, I2=97.54%). Regarding diagnostic tests, for glucometers the pooled availability was 49.5% (95% CI: 37.9% - 61.1%, I2=97.43%), for HbA1c 24.6% (95% CI: 3.1% - 46.1%, I2=91.64), and for lipid profile tests 35.7% (95% CI: 19.4% - 51.9%, I2=83.77%). The median (IQR) affordability in days’ wages was 7 (4.7- 7.5) for short-acting insulin, 4.4 (3.9-4.9) for intermediate-acting insulin, 7.1 (5.8-16.7) for premixed insulin, 0.7 (0.7- 0.7) for glibenclamide, and 2.1 (1.8-2.8) for metformin. Conclusion: The availability of the five essential medicines and three diagnostic tests for diabetes in Africa is suboptimal. The relatively high cost of insulin, HbA1c, and lipid profile tests is a significant barrier to optimal diabetes care. Pragmatic country-specific strategies are urgently needed to address these inequities in access and cost.
Burden of tinea capitis among children in Africa: protocol for a systematic review and meta-analysis of observational studies, 1990–2020
(BMJ Open, 2020) Bongomin, Felix; Olum, Ronald; Nsenga, Lauryn; Baruch Baluku, Joseph
Tinea capitis is the most common form of dermatophytosis among children, contributing significantly to the global burden of skin and hair infections. However, an accurate account of its burden in Africa, where most cases are thought to occur, is lacking. We aim to systematically evaluate the burden, aetiology and epidemiological trend of tinea capitis among children over a 30-year period in Africa. Methods and analysis A systematic review will be conducted using Embase, PubMed, African Journals Online, Web of Science and the Cochrane Library of Systematic Review. These resources will be used to identify studies published between 1990 and December 2020, which report the prevalence, aetiology and trend of tinea capitis among children younger than 18 years in Africa. Articles in English and French will be considered. Two independent reviewers will screen the articles for eligibility, and any discrepancies will be resolved by discussion and consensus between the authors. Methodological quality of all studies will be assessed and critically appraised. We will perform a metaregression to assess the impact of study characteristics on heterogeneity and also to correct the meta-analytical estimates for biases. A qualitative synthesis will be performed, and STATA V.16.0 software will be used to estimate the pooled prevalence and aetiology of tinea capitis. The Mann-Kendall trend test will be use to evaluate the trend in the prevalence of tinea capitis over the study period. Ethics and dissemination Ethical approval from an institutional review board or research ethics committee is not required for this systematic review and meta-analysis. The results will be published in a peer-reviewed journal and presented in conferences.

(BMC Cardiovascular Disorders, 2022) Baruch Baluku, Joseph; Nabwana, Martin; Nalunjogi, Joanitah; Muttamba, Winters; Mubangizi, Ivan; Nakiyingi, Lydia; Ssengooba, Willy; Olum, Ronald; Bongomin, Felix; Andia-Biraro, Irene; Worodria, William
Tuberculosis (TB) and its risk factors are independently associated with cardiovascular disease (CVD). We determined the prevalence and associations of CVD risk factors among people with drug-resistant tuberculosis (DRTB) in Uganda. Methods In this cross-sectional study, we enrolled people with microbiologically confirmed DRTB at four treatment sites in Uganda between July to December 2021. The studied CVD risk factors were any history of cigarette smoking, diabetes mellitus (DM) hypertension, high body mass index (BMI), central obesity and dyslipidaemia. We used modified Poisson regression models with robust standard errors to determine factors independently associated with each of dyslipidaemia, hypertension, and central obesity. Results Among 212 participants, 118 (55.7%) had HIV. Overall, 196 (92.5%, 95% confidence interval (CI) 88.0-95.3) had ≥ 1 CVD risk factor. The prevalence; 95% CI of individual CVD risk factors was: dyslipidaemia (62.5%; 55.4–69.1), hypertension (40.6%; 33.8–47.9), central obesity (39.3%; 32.9–46.1), smoking (36.3%; 30.1–43.1), high BMI (8.0%; 5.0–12.8) and DM (6.5%; 3.7–11.1). Dyslipidaemia was associated with an increase in glycated haemoglobin (adjusted prevalence ratio (aPR) 1.14, 95%CI 1.06–1.22). Hypertension was associated with rural residence (aPR 1.89, 95% CI 1.14– 3.14) and previous history of smoking (aPR 0.46, 95% CI 0.21–0.98). Central obesity was associated with increasing age (aPR 1.02, 95%CI 1.00–1.03), and elevated diastolic blood pressure (aPR 1.03 95%CI 1.00–1.06). Conclusion There is a high prevalence of CVD risk factors among people with DRTB in Uganda, of which dyslipidaemia is the commonest. We recommend integrated services for identification and management of CVD risk factors in DRTB.

Coronavirus disease-2019 (COVID-19) is a potentially life-threatening illness with no established treatment. Cardiovascular risk factors (CRFs) exacerbate COVID-19 morbidity and mortality. Objective: To determine the prevalence of CRF and clinical outcomes of patients hospitalized with COVID-19 in a tertiary hospital in Somalia. Methods: We reviewed the medical records of patients aged 18 years or older with a real-time polymerase chain reaction (RT-PCR)–confirmed COVID-19 hospitalized at the De Martino Hospital in Mogadishu, Somalia, between March and July 2020. Results: We enrolled 230 participants; 159 (69.1%) males, median age was 56 (41–66) years. In-hospital mortality was 19.6% (n = 45); 77.8% in the intensive care unit (ICU) compared with 22.2%, in the general wards (p < 0.001). Age ⩾ 40 years [odds ratio (OR): 3.6, 95% confidence interval (CI): 1.2–10.6, p = 0.020], chronic heart disease (OR: 9.3, 95% CI: 2.2–38.9, p = 0.002), and diabetes mellitus (OR: 3.2, 95% CI: 1.6–6.2, p < 0.001) were associated with increased odds of mortality. Forty-three (18.7%) participants required ICU admission. Age ⩾ 40 years (OR: 7.5, 95% CI: 1.7–32.1, p = 0.007), diabetes mellitus (OR: 3.2, 95% CI: 1.6–6.3, p < 0.001), and hypertension (OR: 2.5, 95% CI: 1.2–5.2, p = 0.014) were associated with ICU admission. For every additional CRF, the odds of admission into the ICU increased threefold (OR: 2.7, 95% CI: 1.2–5.2, p < 0.001), while the odds of dying increased twofold (OR: 2.1, 95% CI: 1.3–3.2, p < 0.001). Conclusions: We report a very high prevalence of CRF among patients hospitalized with COVID-19 in Somalia. Mortality rates were unacceptably high, particularly among those with advanced age, underlying chronic heart disease, and diabetes.

Data on clinical outcomes of patients hospitalized with coronavirus disease 2019 (COVID-19) in private health facilities in Uganda is scarce. We conducted a retrospective cohort study of patients hospitalized with COVID-19 at Case Hospital, Kampala, Uganda, between June 2020 and September 2021. Data of 160 participants (median age 45 years (interquartile range [IQR]: 37–57) and 63.5% male) was analyzed. Seventy-seven (48.1%) participants had non-severe, 18 (11.3%) severe, and 83 (51.9%) critical COVID-19 illness. In 62 participants with chest computed tomography findings, 54 (87%) had bilateral disease, with 22 (35%) having ground-glass opacities. The median duration of hospitalization was 5 days (IQR: 3–9 days). Overall, 18 (11.3%) participants died. Survival at 14 and 28 days was 89% and 72%, respectively. Factors strongly associated with all-cause mortality were as follows: age >50 years (odds ratio [OR]: 8.6, 95% confidence interval [CI]: 1.1–69.2, and ), having at least 1 comorbidity (OR: 3.2, 95% CI: 1.1–8.9, and ), hypertension (OR: 3.2, 95% CI: 1.2–8.6, and ), diabetes mellitus (OR: 2.9, 95% CI: 1.0–8.5, and), and oxygen saturation <92% (OR: 5.1, 95% CI: 1.8–14.4, and ). In this private health facility, mortality was about 1 in 10 patients, and more people presented with critical illness in the second wave of the pandemic, and most deaths occurred after 2 weeks of hospitalization.

Colorectal cancer (CRC) is the most common type of gastrointestinal malignancies and the third leading cause of cancer-related deaths for both sexes worldwide. Although the burden of CRC is highest in developed countries, reports are indicating a rise in the incidence of early-onset CRC in developing countries. In this study, we aimed to determine the prevalence of CRC among patients hospitalized with lower gastrointestinal complaints at a tertiary health facility in Uganda. Methods: We conducted a 10-year retrospective chart review of patients admitted to Mulago National Referral Hospital in Kampala, Uganda, between 1st January 2010 and 31st December 2020. We reviewed all charts of patients admitted to the lower gastrointestinal tract (GIT) ward. Charts with grossly missing data, pediatric patients, and those from other non-lower GIT specialties were excluded. Results: Data of 1476 unique eligible patients were analyzed. Of these,138 had a diagnosis of CRC (prevalence: 9.3%, 95% confidence interval (95% CI): 6.5–11.7%). Among patients with CRC, the female:male ratio was 1:1. The most common site for CRC was the rectum (59.8%, n= 79). For the 138 participants with CRC, 44 had staging data with 72.8% (n=32) having advanced disease, that is, stage 3 or 4. Factors independently associated with CRC were age ≥50 years (adjusted odds ratio (aOR): 4.3, 95% CI: 2.6–7.1, p < 0.001), female sex (aOR: 1.8, 95% CI: 1.2 −2.8, p = 0.005), being widowed (aOR: 2.5, 95% CI: 1.3–5.0, p = 0.006), and presence of any risk factor for CRC (aOR: 5.3, 95% CI: 2.9–9.9, p < 0.001). Conclusion: CRC is relatively common among patients hospitalized with lower GIT complaints, particularly among women and those with known risk factors for CRC. Awareness creation and screening programs should be instituted to allow early diagnosis of CRC in our setting.

Immunization is an important strategy for controlling the COVID-19 pandemic. COVID-19 vaccination was recently launched in Uganda, with prioritization to healthcare workers and high-risk individuals. In this study, we aimed to determine the acceptability of COVID-19 vaccine among persons at high risk of COVID-19 morbidity and mortality in Uganda. Methods: Between 29 March and 14 April 2021, we conducted a cross-sectional survey consecutively recruiting persons at high risk of severe COVID-19 (diabetes mellitus, HIV and cardiovascular disease) attending Kiruddu National Referral Hospital outpatient clinics. A trained research nurse administered a semi-structured questionnaire assessing demographics, COVID-19 vaccine related attitudes and acceptability. Descriptive statistics, bivariate and multivariable analyses were performed using STATA 16.

Several viral, bacterial and fungal co-infections have been associated with increased morbidity and mortality among patients with COVID-19. We report a fatal case of severe COVID-19 pneumonia in a patient with a recent diagnosis of advanced HIV disease complicated by cryptococcal meningitis, disseminated tuberculosis and acute ischemic stroke. Case Presentation: A 37-year-old Ugandan woman was diagnosed with HIV infection 8 days prior to her referral to our center. She was antiretroviral naïve. Her chief complaints were worsening cough, difficulty in breathing, fever and altered mental status for 3 days with a background of a 1-month history of coughing with associated drenching night sweats and weight loss. The reverse transcriptase–polymerase chain reaction for SARS-CoV-2 of her nasopharyngeal swab sample was positive. Chest radiograph demonstrated military pattern involvement of both lungs. The serum and cerebrospinal fluid cryptococcal antigen tests were positive. Urine lipoarabinomannan and sputum GeneXpert were positive for Mycobacterium tuberculosis. Computed tomography of the brain showed a large acute ischemic infarct in the territory of the right middle cerebral artery. Regardless of the initiation of treatment, that is, fluconazole 1200 mg once daily, enoxaparin 60 mg, intravenous (IV) dexamethasone 6 mg once daily, oral fluconazole 1200 mg once daily, IV piperacillin/tazobactam 4.5 g three times daily and oxygen therapy, the patient passed on within 36 hours of admission. Conclusion: Co-infections worsen COVID-19 outcomes.

(Therapeutic advances in infectious disease, 2021) Nsenga, Lauryn; Kajjimu, Jonathan; Olum, Ronald; Ninsiima, Sandra; Kyazze, Andrew Peter; Ssekamatte, Phillip; Kibirige, Davis; Baruch Baluku, Joseph; Andia-Biraro, Irene; Bongomin, Felix
A better understanding of the epidemiology of cryptococcal infection in HIVnegative individuals is an international research interest. Immune dysfunction in diabetes mellitus (DM) significantly increases the risk of acquiring and reactivation of infection due to Cryptococcus neoformans. Risk factors and outcomes of cryptococcosis in DM are not well documented. Objective: The objective of this study was to determine the clinical characteristics and outcomes of cryptococcal infections in persons living with DM. Methods: MEDLINE (via PubMed), EMBASE, and the Cochrane Library databases were searched in November 2020. The searches covered the period between 1980 and 2020.We included studies that reported confirmed cryptococcosis in patients with DM. Reference lists of included articles were also searched, and additional studies were included if appropriate. No language restriction was applied. Single case reports, case series and original articles were included whereas review articles were excluded. Results: A total of 28 studies (24 single case reports, 4 retrospectives) were included involving 47 unique patients from Asia (17 cases), North America (six cases), South America (three cases) and Africa (two cases). Men constituted 75% (n = 18) of the cases. Median age was 60.5 (range: 27–79) years. The majority of the patients had cryptococcal meningitis (68.1%, n = 32) followed by disseminated cryptococcosis (6.4%, n = 7), and others (isolated cutaneous disease one, peritonitis one, pleural one, thyroid one, adrenal one). Diagnosis was achieved through either culture and microscopy (38/47), cryptococcal antigen tests (9/47) or histopathology (9/47) singly or in a combination. All-cause mortality was 38.3% (n = 18). Among those with meningitis mortality was 36.2%. Conclusion: A wide spectrum of cryptococcal infections with varying severity occurs in DM. Mortality remains unacceptably high. There is a need for more studies to characterize better cryptococcal disease in DM.
