Item Accreditation in a Sub Saharan Medical School: a case study at Makerere University(BMC medical education, 2013) Galukande, Moses; Opio, Kenneth; Nakasujja, Noeline; Buwembo, William; Kijjambu, Stephen C.; Dharamsi, Shafik; Luboga, Sam; Sewankambo, Nelson K.; Woollard, RobertOf more than the 2,323 recognized and operating medical schools in 177 countries (world wide) not all are subjected to external evaluation and accreditation procedures. Quality Assurance in medical education is part of a medical school’s ethical responsibility and social accountability. Pushing this agenda in the midst of resource limitation, numerous competing interests and an already overwhelmed workforce were some of the challenges faced but it is a critical element of our medical profession’s social contract. This analysis paper highlights the process of standard defining for Medical Education in a typically low resourced sub Saharan medial school environment. Methods: The World Federation for Medical Education template was used as an operating point to define standards. A wide range of stakeholders participated and meaningfully contributed in several consensus meetings. Effective participatory techniques were used for the information gathering process and analysis. Results: Standards with a clear intent to enhance education were set through consensus. A cyclic process of continually measuring, judging and improving all standards was agreed and defined. Examples of the domains tackled are stated. Conclusion: Our efforts are good for our patients, our communities and for the future of health care in Uganda and the East African region.Item Adolescents, sexual behavior and HIV-1 in rural Rakai district, Uganda(Aids, 1997) Konde-Lule, Joseph K.; Wawer, Maria J.; Sewankambo, Nelson K.; Serwadda, David; Kelly, Robert; Kigongo, DavidTo describe the epidemiology of HIV-1 infection among adolescents aged 13–19 years, in rural Rakai district, Uganda. Annual enumeration and behavioral/serological survey of all consenting adolescents aged 13–19 years at recruitment, residing in 31 randomly selected community clusters. At baseline, of 909 adolescents present in study clusters, 824 (90.6%) provided interview data and serological samples. No adolescents aged 13–14 years were HIV-infected. Among those aged 15–19 years, 1.8% of men and 19.0% of women were HIV-positive. Among young women aged 15–19 years in marital/consensual union, 21.3% were HIV-positive; this rate did not differ significantly from the 29.1% prevalence in those reporting non-permanent relationships; prevalence was significantly lower in women reporting no current relationship (4.3%). After multivariate adjustment, female sex, age 17–19 years, residence in trading centers/trading villages and a history of sexually transmitted disease symptoms remained significantly associated with HIV infection. Seventy-nine per cent of adolescents provided a follow-up serological sample. No young men aged 13–14 years seroconverted during the study; in young women aged 13–14 years, HIV seroincidence was 0.6 per 100 person-years (PY) of observation. Among young men aged 15–19 years, there were 1.1 ± 0.6 seroconversions per 100 PY of observation prior to age 21 years; among women 15–19 years, the incidence rate was 3.9 ± 1.0 per 100 PY of observation prior to age 21 years. The mortality rate among HIV-positive adolescents aged 15–19 years, at 3.9 per 100 PY of observation, was 13-fold higher than that among the HIV-uninfected. By 1992, knowledge of sexual transmission was almost universal, the proportions reporting multiple partners had decreased and condom use had increased over baseline. Adolescents, and young women in particular, are vulnerable to HIV infection. Despite reported behavioral changes, HIV incidence rates remain substantial, and there is a need for innovative HIV preventive measures.Item Age Differences in Sexual Partners and Risk of HIV-1 Infection in Rural Uganda(JAIDS Journal of Acquired Immune Deficiency Syndromes, 2003) Kelly, Robert J.; Gray, Ronald H.; Sewankambo, Nelson K.; Serwadda, David; Wabwire-Mangen, Fred; Lutalo, Tom; Wawer, Maria J.Gender differentials in HIV prevalence and incidence among adolescents and young adults have been observed in studies from Uganda (Fig. 1) (1–4) and other sub- Saharan Africa countries (5–7). Female adolescents are, on average, eight times more likely to be HIV infected than male adolescents. Biologic mechanisms such as immaturity of the reproductive tract in younger women may increase susceptibility to HIV acquisition, and social and cultural practices that promote early sexual activity among women may also be important. Another hypothesized factor is that young women are infected by having sex with older men, who may be more likely to be infected (8–10). This assumption is supported by comparison of age-adjusted HIV prevalence data (4,5,11) and mathematic modeling (12,13). Few empiric studies have examined the effect of age differences between partners on the risk of HIV infection in young women, however (2,14,15). We undertook observational analyses of the sexual behavior characteristics of adolescents in Rakai District, Uganda, to assess the extent to which the ageItem Alcohol use and alcohol-related consequences are associated with not being virally suppressed among persons living with HIV in the Rakai region of Uganda(Drug and Alcohol Dependence, 2021) Miller, Amanda P.; Pitpitan, Eileen V.; Kiene, Susan M.; Raj, Anita; Jain, Sonia; Luisa Zuniga, Marıa; Nabulaku, Dorean; Nalugoda, Fred; Ssekubugu, Robert; Nantume, Betty; Kigozi, Godfrey; Sewankambo, Nelson K.; Kagaayi, Joseph; Reynolds, Steven J.; Grabowski, Kate; Wawer, Maria; Wagman, Jennifer A.Background: Alcohol use is common among persons living with HIV (PWH) in Uganda and associated with poor HIV care outcomes; findings regarding the relationship between alcohol use and viral suppression (VS) have been inconclusive. Methods: Data from two rounds (2017-2020) of the Rakai Community Cohort Study, an open population-based cohort study in the Rakai region, Uganda, were analyzed. Two alcohol exposures were explored: past year alcohol use and alcohol-related consequences. Multivariable models (GEE) were used to estimate associations between alcohol exposures and VS for the overall sample and stratified by sex, adjusting for repeated measurement. Causal mediation by ART use was explored. Results: Over half (55%) of participants (n=3,823 PWH) reported alcohol use at baseline; 37.8% of those reporting alcohol use reported alcohol-related consequences. ART use and VS at baseline significantly differed by alcohol use with person reporting alcohol use being less likely to be on ART or VS. Alcohol use was significantly associated with decreased odds of VS among women but not men (adj. OR 0.72 95% CI 0.58-0.89, p=0.0031). However, among males who use alcohol, experiencing alcohol-related consequences was significantly associated with decreased odds of VS (adj. OR 0.69 95% CI 0.54-0.88, p=0.0034). The relationships between both alcohol exposures and VS were not significant in models restricted to persons on ART. Conclusions: We provide sex-stratified estimates of associations between two alcohol measures and VS in the context of current HIV treatment guidelines. This study confirms that alcohol use is adversely associated with VS but ART use mediates this pathway, suggesting that initiation and retention on ART are critical steps to addressing alcohol-related disparities in VS.Item An Association of Quality of Life and Ageing Perceptions Among Community Dwelling Older Adults in Uganda(2021) Louise -Onoria, Joy; Odokonyero, Raymond; Akena, Dickens; Mwesiga, Emmanuel; Ssuna, Bashir; Sewankambo, Nelson K.; Nakasujja, NoelineUganda’s population, though, largely characterized by young people, has seen the number of people aged 60 and over grow from 686,000 twenty years ago, to 1,433,596 in 2014. Effective caring for the well-being of this population requires strategic and deliberate planning that involves quality of life (QoL) assessments. QoL assessments among the elderly are important in evaluating the efficacy of strategies, such as health interventions, welfare programs, health care, and well-being of the elderly. However, elderly in Uganda face several challenges, ranging from loneliness, poor housing, lack of social and financial support, and poor health. These may negatively affect older persons’ quality of life and consequently their perceptions and attitudes towards aging.Item Availability, functionality and access of blood pressure machines at the points of care in public primary care facilities in Tororo district, Uganda(South African Family Practice, 2021) Besigye, Innocent K.; Okuuny, Vicent; Armstrong-Hough, Mari; Katahoire, Anne R.; Sewankambo, Nelson K.; Mash, Robert; Katamba, AchillesEarly diagnosis of hypertension prevents a significant number of complications and premature deaths. In resource-variable settings, diagnosis may be limited by inadequate access to blood pressure (BP) machines. We sought to understand the availability, functionality and access of BP machines at the points of care within primary care facilities in Tororo district, Uganda. Methods: This was an explanatory sequential mixed-methods study combining a structured facility checklist and key informant interviews with primary care providers. The checklist was used to collect data on availability and functionality of BP machines within their organisational arrangements. Key informant interviews explored health providers’ access to BP machines. Results: The majority of health facilities reported at least one working BP machine. However, Health providers described limited access to machines because they are not located at each point of care. Health providers reported borrowing amongst themselves within their respective units or from other units within the facility. Some health providers purchase and bring their own BP machines to the health facilities or attempted to restore the functionality of broken ones. They are motivated to search the clinic for BP machines for some patients but not others based on their perception of the patient’s risk for hypertension. Conclusion: Access to BP machines at the point of care was limited. This makes hypertension screening selective based on health providers’ perception of the patients’ risk for hypertension. Training in proper BP machine use and regular maintenance will minimise frequent breakdowns.Item Cango Lyec (Healing the Elephant): Chronic Hepatitis B Virus among post-conflict affected populations living in mid-Northern Uganda(PLoS ONE, 2021) Malamba, Samuel S.; Muyinda, Herbert; Ogwang, D. Martin; Katamba, Achilles; Zamar, David S.; Jongbloed, Kate; Sewankambo, Nelson K.; Schechter, Martin T.; Spittal, Patricia M.The legacy of war in Northern Uganda continues to impact people’s health and wellbeing in the Acholi region. Despite increasing attention to Hepatitis B Virus (HBV) in Uganda and globally, concerns remain that unique drivers of infection, and barriers to screening, and treatment, persist among those affected by conflict. Methods Cango Lyec (Healing the Elephant) cohort survey involved conflict-affected adults aged 13– 49 in three mid-Northern Uganda districts (Gulu, Amuru and Nwoya). Baseline (2011–2012) samples were tested for HBV surface antigen (HBsAg), HBV e-antigen (HBeAg), antibodies to HBV surface antigen (HBsAb), antibodies to HBV e-antigen (HBeAb), and antibodies to HBV core antigen (HBcAb). All HBsAg positive samples were tested for IgM antibodies to HBV B core antigen (HBc-IgM) and where available, >6-month follow-up samples were tested for HBeAg and HBV DNA. Data were analyzed using STATA 15 software. Logistic regression accounted for variance due to complex two-stage sampling that included stratification, unequal selection probabilities and community clustering. Odds ratios measured effect potential risk factors associated with chronic HBV infection. Results Among 2,421 participants, 45.7% were still susceptible to HBV infection. HBsAg seropositivity was 11.9% (10.9–13.0), chronic HBV was 11.6% (10.4–12.8), acquired immunity resulting from vaccination was 10.9%, and prior natural infection was 31.5%. Older age (OR:0.570; 95%CI:0.368–0.883) and higher education (OR:0.598; 95%CI:0.412–0.868) were associated with reduced odds of chronic HBV infection. Being male (OR:1.639; 95% CI:1.007–2.669) and having been abducted (OR:1.461; 95%CI:1.055–2.023) were associated with increased odds of infection. Among women, having 1 or 2 pregnancies (compared to none or >2) was associated with increased odds of infection (OR:1.764; 95% CI:1.009–3.084). Conclusion Chronic HBV is endemic in Gulu, Amuru and Nwoya districts. Recommended strategies to reduce post-conflict prevalence include establishment of Northern Uganda Liver Wellness Centres, integration of screening and treatment into antenatal care, and roll out of birth-dose vaccination.Item Cango Lyec (Healing the Elephant): Gender Differences in HIV Infection in Post-conflict Northern Uganda(Journal of Acquired Immune Deficiency Syndromes, 2018) Spittal, Patricia M.; Malamba, Samuel S.; Ogwang, Martin D.; Musisi, Seggane; Ekwaru, J. Paul; Sewankambo, Nelson K.; Pearce, Margo E.; Jongbloed, Kate; Patel, Sheetal H.; Katamba, Achilles; Blair, Alden H.; Muyinda, Herbert; Schechter, Martin T.As previously encamped resettle, potential for rapid HIV transmission in post-conflict Northern Uganda is concerning. Women in particular may be experiencing heightened vulnerability resulting from war-related sexual violence. Setting: Cango Lyec (Healing the Elephant) Project is a cohort involving conflict-affected people in 3 districts in Northern Uganda. Methods: Eight randomly selected communities were mapped, and a census was conducted. Participants aged 13–49 years completed questionnaires in Luo on war-related experiences, mental health, sexual vulnerabilities, and sociodemographics. Blood samples were tested for HIV and syphilis. Baseline data from all sexually active participants was used to determine gender differences in HIV prevalence. Multivariate modeling determined correlates of HIV by gender. Results: Among 2008 participants, HIV prevalence was higher among women [17.2; 95% confidence interval (CI): 14.7 to 19.7] compared to men (10.6; 95% CI: 8.0 to 13.2, ,0.001). Among women, correlates of HIV included: war-related sexual assault [adjusted odds ratio (AOR): 1.95; 95% CI: 1.16 to 3.26]; probable depression (AOR: 2.22; 95% CI: 1.46 to 3.37); probable post-traumatic stress disorder (AOR: 2.03; 95% CI: 1.45 to 2.84); experiencing $12 traumatic events (AOR: 2.04; 95% CI: 1.31 to 3.18); suicide ideation (AOR: 1.67; 95% CI: 1.22 to 2.28); living in a female-headed household (AOR: 2.76; 95% CI: 1.70 to 4.49); first sexual partner $10 years older (AOR: 1.69; 95% CI: 1.07 to 2.67); sex for exchange (AOR: 5.51; 95% CI: 1.76 to 17.31); having 2 (AOR: 2.54; 95% CI: 1.23 to 5.23) or 3+ (AOR: 4.65; 95% CI: 2.65 to 8.18) sexual partners; inconsistent condom use (AOR: 0.40; 95% CI: 0.29 to 0.57); genital ulcers (AOR: 3.08; 95% CI: 2.16 to 4.38); active syphilis (AOR: 4.33; 95% CI: 1.22 to 15.40); and ill health without medical care (AOR: 2.02; 95% CI: 1.22 to 3.34). Among men, correlates of HIV included no condom at sexual debut (AOR: 1.92; 95% CI: 1.30 to 2.83) and genital ulcers (AOR: 4.40; 95% CI: 1.35 to 14.40). Conclusion: Women are disproportionately impacted by HIV, trauma, and depression in this conflict-affected population. Traumainformed HIV prevention and culturally safe mental health initiatives are urgently required.Item Cango Lyec (Healing the Elephant): HIV incidence in post-conflict Northern Uganda(EClinicalMedicine, 2020) Katamba, Achilles; Ogwang, Martin D.; Zamar, David S.; Muyinda, Herbert; Oneka, Alex; Atim, Stella; Jongbloed, Kate; Malamba, Samuel S.; Odongping, Tonny; Friedman, Anton J.; Spittal, Patricia M.; Sewankambo, Nelson K.; Schechter, Martin T.Civil war in Northern Uganda resulted in widespread atrocities, human rights violations, and death, and caused millions to flee to internally displaced persons camps. War-related traumas combined with difficulties accessing HIV prevention and health services has led to extreme HIV-related vulnerability among conflict-affected people who survived the war. Objectives were to (1) determine HIV incidence among conflict-affected people in Northern Uganda and (2) identify vulnerabilities associated with HIV infection. Methods: The Cango Lyec (Healing the Elephant) Project is a prospective cohort involving conflict-affected populations in three districts in Northern Uganda. In 2011, eight randomly selected communities were mapped, and a census was conducted. Consenting participants aged 13 49 years were followed over three rounds of follow-up. Longitudinal data collected included war-related experiences, sexual vulnerabilities, and sociodemographics. Blood samples were tested for HIV-1 at baseline and each 12-month follow-up. Multivariable Cox proportional hazard models determined factors associated with HIV incidence. Findings: Overall, 1920 baseline HIV-negative participants with at least one follow-up contributed 3877 person-years (py) for analysis. Thirty-nine (23 female, 16 male) participants contracted HIV during follow-up. Age- and gender-standardised HIV incidence rate was 102 per 1000py (95%CI: 72-140). Stratified by sex, the age-adjusted HIV incidence was 110 per 1000py (95%CI: 69-166) among women and 94 per 1000py (95%CI: 53-153) among men. Adjusting for confounders, factors associated with risk of HIV included: having been abducted (HR: 370; 95%CI: 187-734), experiencing 12 war-related traumatic events (HR: 291 95%CI: 128-660), suicide ideation (HR: 283; 95%CI: 100-803), having 2 sexual partners (HR: 468; 95%CI: 136-1605), inconsistent condom use (HR: 675; 95%CI: 249-1829), and self-reported genital ulcers (HR: 439; 95%CI: 204-945). Interpretation: Conflict-affected participants who had experienced abduction and multiple traumas during the war were at greater risk of HIV infection. Trauma-informed HIV prevention and treatment services, and culturally-safe mental health initiatives, are urgent for Northern UgandaItem The Cango Lyec Project - Healing the Elephant”: HIV related vulnerabilities of post-conflict affected populations aged 13–49 years living in three Mid-Northern Uganda districts(BMC Infectious Diseases, 2016) Malamba, Samuel S.; Muyinda, Herbert; Spittal, Patricia M.; Ekwaru, John P.; Kiwanuka, Noah; Ogwang, Martin D.; Odong, Patrick; Kitandwe, Paul K.; Katamba, Achilles; Jongbloed, Kate; Sewankambo, Nelson K.; Kinyanda, Eugene; Blair, Alden; Schechter, Martin T.The protracted war between the Government of Uganda and the Lord’s Resistance Army in Northern Uganda (1996–2006) resulted in widespread atrocities, destruction of health infrastructure and services, weakening the social and economic fabric of the affected populations, internal displacement and death. Despite grave concerns that increased spread of HIV/AIDS may be devastating to post conflict Northern Uganda, empirical epidemiological data describing the legacy of the war on HIV infection are scarce. Methods: The ‘Cango Lyec’ Project is an open cohort study involving conflict-affected populations living in three districts of Gulu, Nwoya and Amuru in mid-northern Uganda. Between November 2011 and July 2012, 8 study communities randomly selected out of 32, were mapped and house-to-house census conducted to enumerate the entire community population. Consenting participants aged 13–49 years were enrolled and interviewer-administered data were collected on trauma, depression and socio-demographic-behavioural characteristics, in the local Luo language. Venous blood was taken for HIV and syphilis serology. Multivariable logistic regression was used to determine factors associated with HIV prevalence at baseline. Results: A total of 2954 participants were eligible, of whom 2449 were enrolled. Among 2388 participants with known HIV status, HIV prevalence was 12.2% (95%CI: 10.8-13.8), higher in females (14.6%) than males (8.5%, p < 0.001), higher in Gulu (15.2%) than Nwoya (11.6%, p < 0.001) and Amuru (7.5%, p = 0.006) districts. In this post-conflict period, HIV infection was significantly associated with war trauma experiences (Adj. OR = 2.50; 95%CI: 1.31–4.79), the psychiatric problems of PTSD (Adj. OR = 1.44; 95%CI: 1.06–1.96), Major Depressive Disorder (Adj. OR = 1.89; 95%CI: 1.28–2.80) and suicidal ideation (Adj. OR = 1.87; 95%CI: 1.34–2.61). Other HIV related vulnerabilities included older age, being married, separated, divorced or widowed, residing in an urban district, ulcerative sexually transmitted infections, and staying in a female headed household. There was no evidence in this study to suggest that people with a history of abduction were more likely to be HIV positive. Conclusions: HIV prevalence in this post conflict-affected population is high and is significantly associated with age, trauma, depression, history of ulcerative STIs, and residing in more urban districts. Evidence-based HIV/STI prevention programs and culturally safe, gender and trauma-informed are urgently needed.Item Comparison of methods in the recovery of nucleic acids from archival formalin-fixed paraffin-embedded autopsy tissues(Analytical biochemistry, 2010) Okello, John B.A.; Zurek, Jaymi; Devault, Alison M.; Kuch, Melanie; Okwi, Andrew L.; Sewankambo, Nelson K.; Bimenya, Gabriel S.; Poinar, Debi; Poinar, Hendrik N.Archival formalin-fixed paraffin-embedded (FFPE) human tissue collections are typically in poor states of storage across the developing world. With advances in biomolecular techniques, these extraordinary and virtually untapped resources have become an essential part of retrospective epidemiological studies. To successfully use such tissues in genomic studies, scientists require high nucleic acid yields and purity. In spite of the increasing number of FFPE tissue kits available, few studies have analyzed their applicability in recovering high-quality nucleic acids from archived human autopsy samples. Here we provide a study involving 10 major extraction methods used to isolate total nucleic acid from FFPE tissues ranging in age from 3 to 13 years. Although all 10 methods recovered quantifiable amounts of DNA, only 6 recovered quantifiable RNA, varying considerably and generally yielding lower DNA concentrations. Overall, we show quantitatively that TrimGen’s WaxFree method and our in-house phenol–chloroform extraction method recovered the highest yields of amplifiable DNA, with considerable polymerase chain reaction (PCR) inhibition, whereas Ambion’s RecoverAll method recovered the most amplifiable RNA.Item Determinants of HIV-1 Load in Subjects with Early and Later HIV Infections, in a General-Population Cohort of Rakai, Uganda(Journal of Infectious Diseases, 2004) Gray, Ronald H.; Li, X.; Wawer, Maria J.; Serwadda, David; Sewankambo, Nelson K.; Wabwire-Mangen, Fred; Lutalo, Tom; Kiwanuka, Noah; Kigozi, Godfrey; Nalugoda, Fred; Meehan, Mary P.; Quinn, Thomas C.Human immunodeficiency virus (HIV) type 1 RNA loads were determined for 256 subjects with early (incident) HIV infection and for 1293 subjects with later (prevalent) HIV infection, in a Ugandan cohort. Prevalent infections were classified as latent (0–1 symptoms) and midstage disease ( 2 symptoms), and deaths were ascribed to acquired immunodeficiency syndrome. Among subjects with incident HIV infection, HIV load did not differ by sex, but, among subjects with prevalent HIV infection, it was higher in males than in females. HIV load was highest in subjects (25–29 years old) with incident HIV infection but increased with age in subjects with prevalent HIV infection. Viremia was higher after serconversion than in latency and increased with more advanced disease. Viremia was increased with genital ulcer disease (GUD) in both subjects with incident infection and in those with prevalent infection, and with herpes simplex virus type 2 seropositivity in subjects with incident HIV infection. GUD was consistently associated with higher HIV loads in subjects with incident and those with prevalent HIV infection, suggesting that treatment of GUD might reduce HIV viremia.Item Disclosure of Parental HIV Status to Children: Experiences of Adults Receiving Antiretroviral Treatment at an Urban Clinic in Kampala, Uganda(AIDS research and treatment, 2017) Osingada, Charles P.; Okuga, Monica; Nabirye, Rose C.; Sewankambo, Nelson K.; Nakanjako, DamalieLimited data are available on the experiences of parental HIV disclosure to children in Uganda. We conducted a qualitative study comprising sixteen in-depth interviews and four focus group discussions with parents receiving highly active antiretroviral therapy. Analysis was done using Atlas.ti qualitative research software. Back-and-forth triangulation was done between transcripts of the indepth interviews and focus group discussions, and themes and subthemes were developed. Barriers to parents’ disclosure included perceptions that children are too young to understand what HIV infection means and fears of secondary disclosure by the children. Immediate outcomes of disclosure included children getting scared and crying, although such instances often gave way to more enduring positive experiences for the parents, such as support in adherence to medical care, help in household chores, and a decrease in financial demands from the children. Country-specific interventions are needed to improve the process of parental HIV disclosure to children and this should encompass preparation on how to deal with the immediate psychological challenges associated with the parent’s disclosure.Item Dynamics of Spread of HIV-I Infection in a Rural District of Uganda(British Medical Journal, 1991) Wawer, Maria J.; Serwadda, David; Musgrave, Stanley D; Konde-Lule, Joseph K; Musagara, Maako; Sewankambo, Nelson K.To define the geographical distribution of HIV infection and the community characteristics associated with HIV prevalence in a rural population of Uganda. Seroprevalence survey and interviews of the population aged 13 years and older in 21 randomly selected clusters. Rural population of Rakai district, south west Uganda. 1292 adults, of whom 594 men and 698 women gave a blood sample and answered the questionnaire. HIV status determined by ELISA and western blotting in relation to community characteristics. The weighted seroprevalence of HIV for the district was 12.6% with prevalence by cluster varying from 1.2% to 52.8%. Seroprevalence was highest in main road trading centres (men 26%, women 47%), intermediate in rural trading villages on secondary roads (men 22%, women 29%), and lowest in rural agricultural villages (men 8%, women 9%). For both men and women, multiple regression showed a strong negative association between cluster seroprevalence and the proportion of the population employed in agriculture (beta = -0.677 for men, -0.807 for women). Among women, cluster seroprevalence increased with a higher proportion of the population reporting multiple sex partners (beta = 0.814), external travel (beta = 0.579), and injections (beta = 0.483). Community characteristics, particularly the proportion of the population in agriculture, are associated with HIV prevalence and can be used for targeting interventions. The seroprevalences of HIV suggest spread of infection from main road trading centres, through intermediate trading villages, to rural agricultural villages.Item The effects of male circumcision on female partners’ genital tract symptoms and vaginal infections in a randomized trial in Rakai, Uganda(American journal of obstetrics and gynecology, 2009) Gray, Ronald H.; Kigozi, Godfrey; Serwadda, David; Makumbi, Fredrick; Nalugoda, Fred; Watya, Stephen; Moulton, Laurence; Cheng, Michael Z.; Sewankambo, Nelson K.; Kiwanuka, Noah; Sempijja, Victor; Lutalo, Tom; Kagayii, Joseph; Wabwire-Mangen, Fred; Ridzon, Renée; Bacon, Melanie; Wawer, Maria J.The objective of the study was to assess effects of male circumcision on female genital symptoms and vaginal infections. STUDY DESIGN: Human immunodeficiency virus (HIV)-negative men enrolled in a trial were randomized to immediate or delayed circumcision (control arm). Genital symptoms, bacterial vaginosis (BV), and trichomonas were assessed in HIV-negative wives of married participants. Adjusted prevalence risk ratios (adjPRR) and 95% confidence intervals (CIs) were assessed by multivariable log-binomial regression, intent-to-treat analyses. RESULTS: A total of 783 wives of control and 825 wives of intervention arm men were comparable at enrollment. BV at enrollment was higher in control (38.3%) than intervention arm spouses (30.5%, P .001). At 1 year follow-up, intervention arm wives reported lower rates of genital ulceration (adjPRR, 0.78; 95% CI, 0.63-0.97), but there were no differences in vaginal discharge or dysuria. The risk of trichomonas was reduced in intervention arm wives (adjPRR, 0.52; 95% CI, 0.05- 0.98), as were the risks of any BV (adjPRR, 0.60; 95% CI, 0.38-0.94) and severe BV (prevalence risk ratios, 0.39; 95% CI, 0.24-0.64). CONCLUSION: Male circumcision reduces the risk of ulceration, trichomonas, and BV in female partners.Item Ethical and human rights considerations in public health in low and middle-income countries: an assessment using the case of Uganda’s responses to COVID-19 pandemic(BMC Medical Ethics, 2020) Barugahare, John; Nakwagala, Fredrick Nelson; Mwaka Sabakaki, Erisa; Ochieng, Joseph; Sewankambo, Nelson K.In response to COVID-19 pandemic, the Government of Uganda adopted public health measures to contain its spread in the country. Some of the initial measures included refusal to repatriate citizens studying in China, mandatory institutional quarantine, and social distancing. Despite being a public health emergency, the measures adopted deserve critical appraisal using an ethics and human rights approach. The goal of this paper is to formulate an ethics and human rights criteria for evaluating public health measures and use it to reflect on the ethical propriety of those adopted by the government of Uganda to contain the spread of COVID-19. Main body: We begin by illustrating the value of ethics and human rights considerations for public health measures including during emergencies. We then summarize Uganda’s social and economic circumstances and some of the measures adopted to contain the spread of COVID-19. After reviewing some of the ethics and human rights considerations for public health, we reflect upon the ethical propriety of some of Uganda’s responses to COVID-19. We use content analysis to identify the measures adopted by the government of Uganda to contain the spread of COVID-19, the ethics and human rights considerations commonly recommended for public health responses and their importance. Our study found that some of the measures adopted violate ethics and human rights principles. We argue that even though some human rights can sometimes be legitimately derogated and limited to meet public health goals during public health emergencies, measures that infringe on human rights should satisfy certain ethics and human rights criteria. Some of these criteria include being effective, strictly necessary, proportionate to the magnitude of the threat, reasonable in the circumstances, equitable, and least restrictive. We reflect on Uganda’s initial measures to combat the spread of COVID-19 and argue that many of them fell short of these criteria, and potentially limit their effectiveness. Conclusion: The ethical legitimacy of public health measures is valuable in itself and for enhancing effectiveness of the measures. Such legitimacy depends on the extent to which they conform to ethics and human rights principles recommended for public health measures.Item Evaluation of the Safety and Efficiency of the Dorsal Slit and Sleeve Methods of Male Circumcision Provided by Physicians and Clinical Officers in Rakai, Uganda(BJU international, 2012) Buwembo, Dennis; Musoke, Richard; Kigozi, Godfrey; Sempijja, Victor; Serwadda, David; Makumbi, Frederick; Watya, Stephen; Namuguzi, Dan; Nalugoda, Fred; Kiwanuka, Noah; Sewankambo, Nelson K.; Mangen, Fred Wabwire; Lutalo, Tom; Kiggundu, Valerian; Anyokorit, Margaret; Nkale, James; Kighoma, Nehemia; Wawer, Maria J.; Gray, Ronald H.To assess safety and efficiency of the dorsal slit and sleeve male circumcision (MC) procedures performed by physicians and clinical officers.We evaluated the time required for surgery and moderate / severe adverse events (AEs), among circumcisions by trained physicians and clinical officers using sleeve and dorsal slit methods. Univariate and multivariate regression with robust variance was used to assess factors associated with time for surgery (linear regression) and adverse events (logistic regression). Six physicians and 8 clinical officers conducted 1934 and 3218 MCs, respectively. There were 2471 dorsal slit and 2681 sleeve procedures. The mean duration of surgery was 33 minutes for newly trained providers and decreased to ~20 minutes after ~100 circumcisions. The adjusted mean duration of surgery for dorsal slit was significantly shorter than that for sleeve method (Δ −2.8 minutes, p- <0.001). The duration of surgery was longer for clinical officers than physicians performing the sleeve procedure, but not the dorsal slit procedure. Crude AEs rates were 0.6% for dorsal slit and 1.4% with the sleeve method (p=0.006). However, there were no significant differences after multivariate adjustment. Use of cautery significantly reduced time needed for surgery (Δ − 4.0 minutes, p =0.008), but was associated with higher rates of AEs (adjusted odds ratio 2.13, 95%CI 1.26–3.61, p=0.005).The dorsal slit resection method of male circumcision is faster and safer than sleeve resection, and can be safely performed by non-physicians. However, use of cautery may be inadvisable in this setting.Item Hormonal contraceptive use and HIV-1 infection in a population-based cohort in Rakai, Uganda(Aids, 2003) Kiddugavu, Mohammed; Makumbi, Fred; Wawer, Maria J.; Serwadda, David; Sewankambo, Nelson K.; Wabwire-Mangen, Fred; Lutalo, Tom; Meehan, Mary; Gray, Ronald H.Hormonal contraceptives have been associated with increased risk of HIV acquisition. Methods: The association between hormonal contraception use and HIV acquisition was assessed in a rural community-based cohort in Rakai District, Uganda. A group of 5117 sexually active HIV-negative women were surveyed at 10 month intervals between 1994 and 1999. Information on demographic and sociobehavioral characteristics, use of hormonal contraception (pill and injectable methods), condoms and the number of sexual partners was obtained by home-based interview. HIV incidence rate ratios (IRR) and 95% confidence intervals (CI) associated with hormonal contraception were estimated by multivariate Poisson regression after adjustment for age, condom use, number of sexual partners, marital status, education and history of genital ulcer disease. Results: At one or more interviews, 16.6% of women reported use of hormonal contraceptives and 23.0% reported condom use. HIV incidence was 2.3/100 personyears in hormonal contraceptive users compared with 1.5/100 person-years in non-hormonal contraceptive users (unadjusted IRR, 1.56; 95% CI, 1.00–2.33). After multivariate adjustment, the IRR associated with hormonal contraceptives was reduced to 0.94 (95% CI, 0.53–1.64). The adjusted IRR was 1.12 (95% CI, 0.48–2.56) with oral contraceptive use and 0.84 (95%CI, 0.41–1.72) with injectable methods. Conclusion: Use of hormonal contraception is not associated with HIV acquisition after adjustment for behavioral confoundingItem Human Immunodeficiency Virus Acquisition Associated with Genital Ulcer Disease and Herpes Simplex Virus Type 2 Infection: A Nested Case-Control Study in Rakai, Uganda(The Journal of infectious diseases, 2003) Serwadda, David; Gray, Ronald H.; Sewankambo, Nelson K.; Wabwire-Mangen, Fred; Cheng, Michael Z.; Quinn, Thomas C.; Lutalo, Tom; Kiwanuka, Noah; Kigozi, Godfrey; Nalugoda, Fred; Meehan, Mary P.; Morrow, Rhoda A.; Wawer, Maria J.To assess the timing of symptomatic genital ulcer disease (GUD) relative to human immunodeficiency virus (HIV) seroconversion, we studied 248 case subjects who underwent HIV seroconversion and 496 HIV-negative control subjects, at 3 interview visits conducted at 10-month intervals: visit 1, before HIV acquisition; visit 2, after seroconversion; and visit 3, 10 months after detection of seroconversion. Odds ratios (ORs) and 95% confidence intervals (CIs), for HIV acquisition, were estimated by logistic regression. HIV load was measured by RNA–polymerase chain reaction, and herpes simplex virus type 2 (HSV-2) serologic testing used HerpeSelect EIA with Western blot confirmation. The OR of HSV-2 seropositivity associated with HIV acquisition was 1.7 (95% CI, 1.2–2.4). Prevalence of GUD was increased among case subjects, at visits 2 (OR, 3.2; 95% CI, 1.9– 5.3) and 3 (OR, 2.1; 95% CI, 1.1–3.9). HIV load was increased in HSV-2–seropositive case subjects, compared with that in HSV-2–seronegative subjects, at 5 (Pp.04) and 15 (Pp.02) months after seroconversion. HIV acquisition is associated with HSV-2 seropositivity, and GUD is increased after seroconversion. HIV load is increased in HSV-2–positive subjects who seroconverted, suggesting a role for treatment of HSV-2 infection in HSV-2–seropositive, dually infected individuals.Item “I Felt very Small and Embarrassed by the Health Care Provider When I Requested to be Tested for Syphilis”: Barriers And Facilitators of Regular Syphilis and HIV Testing among Female Sex Workers in Uganda(BMC Public Health, 2021) Muhindo, Richard; Mujugira, Andrew; Castelnuovo, Barbara; Sewankambo, Nelson K.; Ratanshi, Rosalind Parkes; Tumwesigye, Nazarius Mbona; Joloba, Edith Nakku; Kiguli, JulietPeriodic testing of female sex workers (FSW) for sexually transmitted infections (STIs) is a core component of global and national responses to achieve population-level STI elimination. We conducted a qualitative study to explore barriers and facilitators of regular syphilis and HIV testing among FSW in Uganda.Within a quasi-experimental study among 436 FSW to assess the effect of peer education and text message reminders on uptake of regular STI and HIV testing among FSW, we conducted 48 qualitative interviews in four cities in Uganda from August–December 2018. We purposively selected FSW who tested for syphilis and HIV every 3–6 months; 12 FSW were interviewed in each city. Sex worker interviews explored: 1) reasons for periodic syphilis and HIV testing; 2) barriers and facilitators of testing; 3) experiences of testing; and 4) challenges faced while seeking testing services. Data were analyzed using thematic content analysis.Thematic analysis revealed individual- and health system-level barriers and facilitators of testing. For syphilis, barriers were a) interpersonal stigma, low perceived severity of syphilis and testing misconceptions (individual); and b) judgmental provider attitudes, paucity of facilities offering syphilis testing, stockouts of test kits and high cost (health system). Facilitators were c) desire to remain healthy, get married and have children, knowing the benefits of early treatment, influence of male partners/clients and normative testing behaviors (individual); and d) sex worker clinics offering dual syphilis/HIV testing (health system). For HIV, barriers included: a) internalized stigma (individual); and b) unfavorable clinic hours, stigma, discrimination, and unfriendly provider (health system). Facilitators were a) motivations to stay healthy and attract clients, habitual testing, self-efficacy, doubts about accuracy of negative test results, and use of post-exposure prophylaxis (individual); and d) availability of testing facilities (health system). Syphilis and HIV had similar testing barriers and facilitators.HIV programs are likely to be important entry points for syphilis testing among FSW. Multi-level interventions to address testing barriers should consider focusing on these service delivery points. Extending the dual syphilis and HIV testing approach to FSW may improve testing uptake for both infections at public health facilities and decrease population-level incidence.
