    Understanding dementia aetiology in Uganda
    (John Wiley and Sons Inc, 2025-01) Prynn, Josephine E;; Mugisha, Joseph;; Steves, Claire J ;; Peto, Tunde;; Kimono, Beatrice;; Prince, Martin J
    Background The prevalence of dementia in low‐ and middle‐income countries is increasing, yet epidemiological data from African populations remains scarce. Crucial risk factors differ in Africa from more intensively studied global areas, including a high burden of cerebrovascular disease (evidenced by high stroke incidence) and HIV, but lower rates of other risk factors such as physical inactivity. In the pre‐antiretroviral therapy era, dementia was a common consequence of HIV infection. However, it is not clear from existing literature what effect, if any, chronic and well‐controlled HIV has on cognition with ageing. Understanding dementia aetiology in African settings has been limited by the expensive and invasive nature of biomarker testing. This study leverages developments in biomarker technology to examine the drivers of dementia in older Ugandans. This includes using blood‐based biomarkers for Alzheimer’s disease and retinal imaging with automated analysis of vascular morphology as a proxy for cerebrovascular disease. Among older adults in a Ugandan population, this study will evaluate the prevalence of dementia, establish the pathological processes underlying dementia to inform risk reduction strategies, and examine the impact of dementia on individuals and their caregivers. Methods The study is nested within the existing General Population Cohort (GPC) run by the Medical Research Council /Uganda Virus Research Institute (MRC/UVRI) & London School of Hygiene and Tropical Medicine (LSHTM) Research Unit and includes all adults over 60. In Step 1, cohort participants will undergo cognitive screening. Based on screening scores, a subgroup will undergo cognitive assessments using tools developed by the 10/66 Dementia Research Group to determine dementia diagnoses. Step 2 is a case control study of people with and without dementia using antecedent data, questionnaires, physical assessment, retinal imaging, and Alzheimer’s blood‐based biomarkers. We will also compare disability, frailty, quality of life, and social engagement in people with and without dementia. Results We will identify the prevalence of dementia, odds ratios, and population attributable fractions for both modifiable risk factors for dementia and the pathological processes of Alzheimer’s pathology and cerebrovascular disease. Conclusions This will be first study in Africa to examine pathological processes leading to dementia including markers of Alzheimer’s and cerebrovascular disease.

    Current evidence and prevalence of dementia care in EastAfrica-Uganda a systematic review
    (John Wiley and Sons Inc, 2025-01) Moses, Waiswa;; Simon, Wandera;; Melinda, Namuli ;; Davidson, Kalsonid
    Background Uganda has an increasing population of older persons who require special attention to reduce the burden of dementia. With the growing prevalence of dementia worldwide, two third of the people with dementia are projected to be from the de‐eloping countries by 2050. Few studies have been conducted on the prevalence of dementia and its association with central nervous system (CNS) infections among older persons in African settings, particularly in Uganda. Methods The study was conducted in March 2022 among 434 older persons aged 50 and above years who were selected by multistage sampling. Data were collected using an inter‐viewer administered questionnaire supplemented with information from participant’s medical records and a brief community screening instrument for dementia. The instrument classifies dementia into unlikely, probable or possible dementia. Data were entered in duplicate into EpiData version 3.0, then transferred to statistical package for social sciences (SPSS) version 23 for statistical analysis. Results Our study found almost one in four (23%) of the older persons in tororo district eastern part of Uganda were suffering from probable or possible dementia. Our study further found that older persons with a positive history of central nervous system infections (CNS) had nearly five times higher odds of having probable or possible dementia compared to their counterparts (cOR: 4,5: 2.76‐7.23; p< 0.001). Being in advanced age of 70+ years (aOR: 2.6; 5:4; 1.4 ‐20.5; p = 0.013), and chronic headache (aOR: 1.9; 1.1‐3.1:p = 0.019) were independent predictors of probable or possible dementia among participants in the study. Conclusion This study highlights dementia as a growing public health issue in the African settings, in Uganda with over 1243 individuals affected in 2021. The findings emphasize the urgent need for investment in research and specialized services for older adults, particularly those with dementia.

    Factors Associated with Reintegration Trajectory Following Female Genital Fistula Surgery in Uganda
    (AJOG Global Reports, 2023-11-13) Bigley, Rachel; Barageine, Justus; Nalubwama, Hadija; Obore, Susan; Byamugisha, Josaphat; El Ayadi, Alison M.
    A female genital fistula, primarily caused by prolonged obstructed labor or after cesarean delivery in resource-limited countries, affects 500,000 to 2,000,000 women worldwide. Fistula is preventable with timely access to high-quality obstetrical care. Access to surgical repair of a female genital fistula has greatly increased over time. However, research surrounding postrepair reintegration, the process of returning to an individual's normal life, remains limited, and further efforts are needed to understand the factors shaping women's ability to rebuild their relationships and lives following repair. This study aimed to characterize the 12-month reintegration trajectory after female genital fistula repair by participant sociodemographic and clinical characteristics. This study analyzed quantitative survey and medical record data of women (N=60) participating in a longitudinal cohort study assessing recovery after genital fistula repair in Uganda, with baseline and 4 quarterly follow-up assessments in 12 months. The primary outcome of reintegration was assessed using a 19-item postfistula repair reintegration instrument (range, 0–100) where a higher score represents better reintegration. Predictors of interest included parity and living children, quality of life, depressive symptoms at baseline, self-esteem, stigma, trauma, physical symptoms, and social support. We described participant baseline characteristics using means and proportions and estimated a series of mixed-effects linear regression models, including interactions of characteristics with time to understand how these characteristics influence reintegration trajectory in the 12 months after repair. The participants’ physical and psychosocial morbidities at baseline were high; more than 80% of participants reported fistula-related physical symptoms, 82% of participants described their general health as poor, and measures of self-esteem, overall social support, and overall quality of life were low. The mean reintegration score at baseline was 33 (standard deviation, 20), which increased to 78 (standard deviation, 19) at 12 months after fistula repair. The participant sociodemographic characteristics statistically associated with reintegration included any living children (β, 1.08; 95% confidence interval, −0.08 to 2.23). Moreover, psychosocial factors significantly affected reintegration with steeper trajectories for women with depressive symptoms (β, 0.89; 95% confidence interval, 0.02–1.75) or women experiencing internalized stigma (β, 0.05; 95% confidence interval, −0.00 to 0.11) and less steep for those with higher self-esteem (β, −0.11; 95% confidence interval, −0.24 to 0.01), overall social support (β, −0.06; 95% confidence interval, −0.12 to −0.01), and partner support (β, −0.21; 95% confidence interval, −0.35 to −0.07). Understanding the prominent factors associated with differences in reintegration trajectories across the year after genital fistula surgery has the potential to inform interventions that mitigate challenges and improve women's postrepair recovery experiences.

    Who pays to treat malaria and how much? Analysis of the cost of illness, equity and economic burden of malaria in Uganda
    (Oxford University Press, 2025-01) Snyman, Katherine;; Pitt, Catherine; Aturia, Angelo ; Aber, Joyce; Gonahasa, Samuel; Namuganga, Jane Frances; Nankabirwa, Joaniter; Arinaitwe, Emmanuel; Maiteki-Sebuguzi, Catherine;; Katamba, Henry;; Opigo, Jimmy;; Matovu, Fred;; Dorsey, Grant;; Kamya, Moses R;; Ochieng, Walter;; Staedke, Sarah G
    Case management of malaria in Africa has evolved markedly over the past 20 years and updated cost estimates are needed to guide malaria control policies. We estimated the cost of malaria illness to households and the public health service and assessed the equity of these costs in Uganda. From December 2021 to May 2022, we conducted a costing exercise in eight government-run health centres covering seven sub-regions, collecting health service costs from patient observations, records review and a time-and-motion study. From November 2021 to January 2022, we gathered data on households' cost of illness from randomly selected households for 614 residents with suspected malaria. Societal costs of illness were estimated and combined with secondary data sources to estimate the total economic burden of malaria in Uganda. We used regression analyses and concentration curves to assess the equity of household costs across age, geographic location and socio-economic status. The mean societal economic cost of treating suspected malaria was $15.12 [95% confidence interval (CI): 12.83-17.14] per outpatient and $27.21 (95% CI: 20.43-33.99) per inpatient case. Households incurred 81% of outpatient and 72% of inpatient costs. Households bore nearly equal costs of illness, regardless of socio-economic status. A case of malaria cost households in the lowest quintile 26% of per capita monthly consumption, while a malaria case only cost households in the highest quintile 8%. We estimated the societal cost of malaria treatment in Uganda was $577 million (range: $302 million-1.09 billion) in 2021. The cost of malaria remains high in Uganda. Households bear the major burden of these costs. Poorer and richer households incur the same costs per case; this distribution is equal, but not equitable. These results can be applied to parameterize future economic evaluations of malaria control interventions and to evaluate the impact of malaria on Ugandan society, informing resource allocations in malaria prevention.

    Beliefs of Pentecostal pastors on the use of antiretroviral treatment among Pentecostal Christians living with HIV in a suburb of Cape Town-South Africa: a community health systems lens
    (Oxford University Press, 2025-01) Azia, Ivo Nchendia;; Nyembezi, Anam;; Carelse, Shernaaz ;; Mukumbang, Ferdinand C
    The global public health community accepts antiretroviral therapy (ART) for controlling and managing human immunodeficiency virus (HIV). However, within some communities, claims of faith or miraculous healing of HIV and acquired immunodeficiency syndrome (AIDS) by Pentecostal pastors continue to spark controversies. This paper reports on an exploratory qualitative study to explore the beliefs held by Pentecostal pastors regarding the use of ART among Pentecostal Christians who are living with HIV. Twenty (20) purposively selected Pentecostal pastors from two informal settlements in Cape Town, South Africa, participated in the study. Open-ended, semi-structured, in-depth individual interviews were conducted on their religious beliefs concerning ART adherence. Interviews were conducted in English, audiotaped and transcribed verbatim before being imported into the Atlas.ti 2023 software program for thematic data analysis. Since our study was guided by the relational community health system model a hybrid deductive-inductive thematic analysis was used. Two contrasting themes about the influence of the religious beliefs of Pentecostal pastors were identified. The first theme and its associated subthemes highlight the lack of basic HIV and ART knowledge among pastors. Consequently, these pastors tend to nudge their Christians to rely more on faith and spiritual healing at the expense of adherence to ART. The second theme and its related sub-themes suggest that some pastors possess some basic HIV knowledge and understand the role of ART and how it works. This group of pastors advise their congregants to use ART and other healthcare services in tandem with spiritual rituals, faith and prayers. Our findings highlight the need for functional community-based structures, such as community health committees and health facility management committees, in settings where complex interaction within the belief systems, practices and norms of some stakeholders can influence people's health-seeking behaviours such as adherence to chronic medications like ART.

    Finding the missing men with tuberculosis: a participatory approach to identify priority interventions in Uganda
    (Oxford University Press, 2025-01) Nidoi, Jasper; Pulford, Justin; Wingfield, Tom; Rachael, Thomson; Ringwald, Beate; Katagira, Winceslaus; Muttamba, Winters; Nattimba, Milly; Namuli, Zahra; Kirenga, Bruce
    Gender impacts exposure and vulnerability to tuberculosis (TB) evidenced by a higher prevalence of both TB disease and missed TB diagnoses among men, who significantly contribute to new TB infections. We present the formative research phase of a study, which used participatory methods to identify gender-specific interventions for systematic screening of TB among men in Uganda. Health facility-level data were collected at four Ugandan general hospitals (Kawolo, Gombe, Mityana and Nakaseke) among 70 TB stakeholders, including healthcare workers, TB survivors, policymakers and researchers. Using health-seeking pathways, they delineated and compared men’s ideal and actual step-by-step TB healthseeking processes to identify barriers to TB care. The stepping stones method, depicting barriers as a ‘river’ and each ‘steppingstone’ as a solution, was employed to identify interventions which would help link men with TB symptoms to care. These insights were then synthesized in a co-analysis meeting with 17 participants, including representatives from each health facility to develop a consensus on proposed interventions. Data across locations revealed the actual TB care pathway diverted from the ideal pathway due to health system, community, health worker and individual-level barriers such as delayed health seeking, unfavourable facility operating hours and long waiting times that conflicted with men’s work schedules. Stakeholders proposed to address these barriers through the introduction of male-specific services; integrated TB services that prioritize X-ray screening for men with cough; healthcare worker training modules on integrated male-friendly services; training and supporting TB champions to deliver health education to people seeking care; and engagement of private practitioners to screen for TB. In conclusion, our participatory co-design approach facilitated dialogue, learning and consensus between different health actors on context-specific, person-centred TB interventions for men in Uganda. The acceptability, effectiveness and cost effectiveness of the package will now be evaluated in a pilot study. Keywords: Tuberculosis, participatory research, gender, healthcare-seeking behaviour

    Development and Preliminary Validation of a Post-fistula Repair Reintegration Instrument among Ugandan Women
    (Reproductive health, 2017-09-02) El Ayadi, Alison; Nalubwama, Hadija; Barageine, Justus; Byamugisha, Josaphat; Kakaire, Othman; Mwanje, Haruna; Miller, Suellen
    Obstetric fistula is a debilitating and traumatic birth injury affecting 2–3 million women globally, mostly in sub-Saharan Africa and Asia. Affected women suffer physically, psychologically and socioeconomically. International efforts have increased access to surgical treatment, yet attention to a holistic outcome of post-surgical rehabilitation is nascent. We sought to develop and pilot test a measurement instrument to assess post-surgical family and community reintegration. We conducted an exploratory sequential mixed-methods study, beginning with 16 in-depth interviews and four focus group discussions with 17 women who underwent fistula surgery within two previous years to inform measure development. The draft instrument was validated in a longitudinal cohort of 60 women recovering from fistula surgery. Qualitative data were analyzed through thematic analysis. Socio-demographic characteristics were described using one-way frequency tables. We used exploratory factor analysis to determine the latent structure of the scale, then tested the fit of a single higher-order latent factor. We evaluated internal consistency and temporal stability reliability through Raykov’s ρ and Pearson’s correlation coefficient, respectively. We estimated a series of linear regression models to explore associations between the standardized reintegration measure and validated scales representing theoretically related constructs. Themes central to women’s experiences following surgery included resuming mobility, increasing social interaction, improved self-esteem, reduction of internalized stigma, resuming work, meeting their own needs and the needs of dependents, meeting other expected and desired roles, and negotiating larger life issues. We expanded the Return to Normal Living Index to reflect these themes. Exploratory factor analysis suggested a four-factor structure, titled ‘Mobility and social engagement’, ‘Meeting family needs’, ‘Comfort with relationships’, and ‘General life satisfaction’, and goodness of fit statistics supported a higher-order latent variable of ‘Reintegration.’ Reintegration score correlated significantly with quality of life, depression, self-esteem, stigma, and social support in theoretically expected directions. As more women undergo surgical treatment for obstetric fistula, attention to the post-repair period is imperative. This preliminary validation of a reintegration instrument represents a first step toward improving measurement of post-surgical reintegration and has important implications for the evidence base of post-surgical reintegration epidemiology and the development and evaluation of fistula programming.

    Reintegration Needs of Young Women following Genitourinary Fistula Surgery in Uganda
    (Int Urogynecol J, 2019-02-27) Emasu, Alice; Matovu, Alphonsus; Alia, Godfrey; Barageine, Justus Kafunjo
    Genitourinary fistulas (usually arising following prolonged obstructed labor) are particularly devastating for women in low-income counties. Surgical repair is often difficult and delayed. While much attention has been devoted to technical surgical issues, the challenges of returning to normal personal, family, and community life after surgical treatment have received less scrutiny from researchers. We surveyed young Ugandan women recovering from genitourinary fistula surgery to assess their social reintegration needs following surgery.

    Development and Pilot Test of a Multi‑Component Intervention to Support Women’s Recovery from Female Genital Fistula
    (Int Urogynecol J, 2024-06-24) Barageine,Justus K.; Nalubwama, Hadija; Obore, Susan; Mirembe, Esther; El Ayadi, Alison M.
    We evaluated a pilot multi-component reintegration intervention to improve women’s physical and psychosocial quality of life after genital fistula surgery. Twelve women undergoing fistula repair at Mulago Specialized Women and Neonatal Hospital (Kampala, Uganda) anticipated in a 2-week multi-component intervention including health education, psychosocial therapy, physiotherapy, and economic investment. We assessed feasibility through recruitment, retention, and adherence, acceptability through intervention satisfaction, and preliminary effectiveness through reintegration, mental health, physical health, and economic status. We collected quantitative data at enrollment, 6 weeks, 3 months, and 6 months. We conducted in-depth interviews with six participants. Quantitative data are presented descriptively, and qualitative data analyzed thematically. Participants had a median age of 34.5 years (25.5–38.0), 50% were married/partnered, 42% were separated, 50$ had completed less than primary education, and 67% were unemployed. Mean number of sessions received was 12 for health education (range 5–15), 8 for counseling (range 8–9), and 6 for physiotherapy (range 4–8). Feasibility was demonstrated by study acceptance among all those eligible (100%); comfort with study measures, data collection frequency and approach; and procedural fidelity. Acceptability was high; all participants reported being very satisfied with the intervention and each of the components. Participant narratives echoed quantitative findings and contributed nuanced perspectives to understanding approach and content. Our results suggest that the intervention and associated research were both feasible and acceptable, and suggested certain modifications to the intervention protocol to reduce participant burden. Further research to determine the effectiveness of the intervention above and beyond surgery alone with regard to the health and well-being of women with fistulas is warranted.

    Maternal and Umbilical Cord Blood Lactate for Predicting Perinatal Death: a secondary analysis of data from a randomized controlled trial
    (BMC Pediatr, 2023-04-18) Musaba, Milton W.; Nambozo, Brendah; Barageine, Justus K.; Ndeezi, Grace
    In high resource settings, lactate and pH levels measured from fetal scalp and umbilical cord blood are widely used as predictors of perinatal mortality. However, the same is not true in low resource settings, where much of perinatal mortality occurs. The scalability of this practice has been hindered by difficulty in collecting fetal scalp and umbilical blood sample. Little is known about the use of alternatives such as maternal blood, which is easier and safer to obtain. Therefore, we aimed to compare maternal and umbilical cord blood lactate levels for predicting perinatal deaths. This was secondary analysis of data from a randomized controlled trial assessing the effect of sodium bicarbonate on maternal and perinatal outcomes among women with obstructed labour at Mbale regional referral hospital in Eastern Uganda. Lactate concentration in maternal capillary, myometrial, umbilical venous and arterial blood was measured at the bedside using a lactate Pro 2 device (Akray, Japan Shiga) upon diagnosis of obstructed Maternal lactate was a poor predictor of perinatal death, but umbilical artery lactate has a high predictive value. There is need for future studies on the utility of amniotic fluid in predicting intrapartum perinatal deaths. labour. We constructed Receiver Operating Characteristic curves to compare the predictive ability of maternal and umbilical cord lactate and the optimal cutoffs calculated basing on the maximal Youden and Liu indices. Perinatal mortality risk was: 102.2 deaths per 1,000 live births: 95% CI (78.1–130.6). The areas under the ROC curves were 0.86 for umbilical arterial lactate, 0.71 for umbilical venous lactate, and 0.65 for myometrial lactate, 0.59 for maternal lactate baseline, and 0.65 at1hr after administration of bicarbonate. The optimal cutoffs for predicting perinatal death were 15 0.85 mmol/L for umbilical arterial lactate, 10.15mmol/L for umbilical venous lactate, 8.75mmol/L for myometrial lactate, and 3.95mmol/L for maternal lactate at recruitment and 7.35mmol/L after 1 h.

    Beyond repair - family and community reintegration after obstetric fistula surgery: study protocol
    (Reprod Health, 2015-12-18) Byamugisha, Josaphat; Obore, Susan; Kakaire, Othman; Nalubwama, Hadija; Miller, Suellen
    Obstetric fistula is a debilitating birth injury that affects an estimated 2–3 million women globally, most in sub-Saharan Africa and Asia. The urinary and/or fecal incontinence associated with fistula affects women physically, psychologically and socioeconomically. Surgical management of fistula is available with clinical success rates ranging from 65–95 %. Previous research on fistula repair outcomes has focused primarily on clinical outcomes without considering the broader goal of successful reintegration into family and community. The objectives for this study are to understand the process of family and community reintegration post fistula surgery and develop a measurement tool to assess long-term success of post-surgical family and community reintegration.

    “I am Alone and Isolated”: A Qualitative Study of Experiences of Women Living with Genital Fistula in Uganda
    (BMC women's health, 2015-09-10) Barageine, Justus Kafunjo; Beyeza-Kashesya, Jolly; Byamugisha, Josaphat K.; Tumwesigye, Nazarius Mbona; Almroth, Lars; Faxelid , Elisabeth
    Globally, 2–3 million women are estimated to have a genital fistula, with an annual incidence of 50,000–100,000 women. Affected women remain silent within their communities, and their experiences often go unnoticed. Our objective was to explore the experiences of Ugandan women living with genital fistulas to understand how their lives were affected and how they coped with the condition. We conducted 8 focus group discussions (FGDs) with 56 purposively selected women with a genital fistula seeking treatment at Mulago Hospital, Uganda. Data were transcribed and analysed using qualitative content analysis. Women with a fistula were living a physically changed and challenging life, living socially deprived and isolated, living psychologically stigmatised and depressed, and living marital and sexual lives that were no longer joyful. The women’s experiences were full of life changes and coping strategies, and they used both problem- and emotion-focused coping strategies to deal with the challenges. They devised ways to reduce the smell of urine to reduce the stigma, rejection and isolation. While trying to cope, the women found themselves alone and isolated. Women either isolated themselves or were isolated by society, including by close relatives and their husbands. Their sex lives were no longer enjoyable, and generally, women felt a loss of their marital and sexual rights. Women with a fistula make adjustments in their lives to cope with the physical, social, psychological and sexual challenges. They use both problem- and emotion-focused coping to minimise their sense of isolation, as well as the rejection and stigma associated with fistula. These findings are essential for counselling patients, families and community members affected by a fistula. In similar contexts, health programmes should go beyond fistula closure and target communities and families to reduce the stigma and isolation faced by women with genital fistula.

    Contraceptive Preferences and Adoption Following Female Genital Fistula Surgery in Uganda: A Mixed‑Methods Study
    (Reproductive Health, 2023-08-19) El Ayadi, Alison M.; Nalubwama, Hadija; Kakaire, Othman; Miller, Suellen; Barageine, Justus; Byamugisha, Josaphat; Obore, Susan; Harper, Cynthia C.
    Female genital fistula, largely caused by prolonged obstructed labour, is treated by surgical repair. Preventing pregnancy for a minimum period post-repair is recommended to ensure adequate healing and optimize post-repair outcomes. We examined contraceptive preferences and use among Ugandan fistula patients (n = 60) in the year following genital fistula surgery using mixed-methods. Sexual activity, contraceptive use and pregnancy status were recorded quarterly for 12 months after surgery. In-depth interviews among purposively selected participants (n = 30) explored intimate relationships, sexual experiences, reproductive intentions, and contraceptive use. Median participant age was 28 years and almost half (48%) were married or living with partners. Counselling was provided to 97% of participants on delaying sexual intercourse, but only 59% received counselling on contraception. Sexual activity was reported by 32% after 6 months and 50% after 12 months. Eighty-three percent reported not trying for pregnancy. Among sexually active participants, contraceptive use was low at baseline (36%) but increased to 73% at 12 months. Six (10%) women became pregnant including two within 3 months post-repair. Interview participants who desired children immediately were young, had fewer children, experienced stillbirth at fistula development, and felt pressure from partners. Women adopted contraception to fully recover from fistula surgery and avoid adverse outcomes. Others simply preferred to delay childbearing. Reasons cited for not adopting contraception included misconceptions related to their fertility and to contraceptive methods and insufficient or unclear healthcare provider advice on their preferred methods. A high proportion of patients were not counselled by healthcare providers on contraception. Provision of comprehensive patient-centred contraceptive counselling at the time of fistula surgery and beyond is important for patients to optimize healing from fistula and minimize recurrence, as well as to meet their own reproductive preferences.

    Identifying Opportunities for Prevention of Adverse Outcomes Following Female Genital Fistula Repair: Protocol for a Mixed‑Methods Study in Uganda
    (Reproductive Health, 2025) El Ayadi, Alison M.; Obore, Susan; Kirya, Fred; Nalubwama, Hadija; Getahun, Monica; Eyul, Patrick; Twine, Robert; Andrew, Erin V. W.; Barageine, Justus K.
    Female genital fistula is a traumatic debilitating injury, frequently caused by prolonged obstructed labor, affecting between 500,000-2 million women in lower-resource settings. Vesicovaginal fistula causes urinary incontinence, and other morbidity may occur during fistula development. Women with fistula are stigmatized, limit social and economic engagement, and experience psychiatric morbidity. Improved surgical access has reduced fistula consequences yet post-repair risks impacting quality of life and well-being include fistula repair breakdown or recurrence and ongoing or changing urine leakage or incontinence. Limited evidence on risk factors contributing to adverse outcomes hinders interventions to mitigate adverse events. This study aims to quantify these adverse risks and inform clinical and counseling interventions to optimize women’s health and quality of life following fistula repair through: identifying predictors and characteristics of post-repair fistula breakdown and recurrence (Objective 1) and post-repair incontinence (Objective 2), and to identify feasible and acceptable intervention strategies (Objective 3). This mixed-methods study incorporates a prospective cohort of women with successful vesicovaginal fistula repair at approximately 12 fistula repair centers in Uganda (Objectives 1-2) followed by qualitative inquiry among key stakeholders (Objective 3). Cohort participants will have a baseline visit at the time of surgery followed by data collection at 2 weeks, 6 weeks, 3 months and quarterly thereafter for 3 years. Primary predictors to be evaluated include patient-related factors, fistula-related factors, fistula repair-related factors, and post-repair behaviors and exposures, collected via structured questionnaire at all data collection points. Clinical exams will be conducted at baseline, 2 weeks post-surgery, and for outcome confirmation at symptom development. Primary outcomes are fistula repair breakdown or fistula recurrence and post-repair incontinence. In-depth interviews will be conducted with cohort participants (n ~ 40) and other key stakeholders (~ 40 including family, peers, community members and clinical/social service providers) to inform feasibility and acceptability of recommendations.

    Incidence and Determinants of Perinatal Mortality among Women with Obstructed Labour in Eastern Uganda: A Prospective Cohort Study
    (Maternal health, neonatology and perinatology, 2021-07-15) Musaba, Milton W. Musaba; Ndeezi, Grace; Barageine, Justus K.; Wandabwa, Julius N.; Mukunya, David; Waako, Paul; Odongkara, Beatrice; Arach, Agnes; Mugabe, Kenneth Tulya-muhika; Napyo, Agnes Kasede; Nankabirwa, Victoria; Tumwine, James K.
    In Uganda, the incidence and determinants of perinatal death in obstructed labour are not well documented. We determined the incidence and determinants of perinatal mortality among women with obstructed labour in Eastern Uganda. Between July 2018 and September 2019, 584 with obstructed labour were recruited and followed up to the 7th day postnatal. Information on maternal characteristics, obstetric factors and laboratory parameters was collected. Each patient received the standard perioperative care. We used a generalized linear model for the Poisson family, with a log link and robust variance estimation to determine the association between the exposure variables and perinatal death. Of the 623 women diagnosed with obstructed labour, 584 met the eligibility criteria. There were 24 fresh still births (FSB) and 32 early neonatal deaths (ENND) giving an FSB rate of 43.8 (95% CI 28.3–64.4) deaths per 1000 total births; early neonatal death rate of 58.4 (95% CI 40.3–81.4) deaths per 1000 and an overall perinatal mortality rate of 102.2 (95% CI 79.4–130.6) deaths in the first 7 days of life. A mother being referred in active labour adjusted risk ratio of 2.84 (95% CI: 1.35–5.96) and having high blood lactate levels at recruitment adjusted risk ratio 2.71 (95% CI: 1.26–4.24) were the determinants of perinatal deaths. The incidence of perinatal death was four times the regional and national average. Babies to women referred in active labour and those with high maternal blood lactate were more likely to die.

    The Social, Economic, Emotional, and Physical Experiences Of Caregivers for Women with Female Genital Fistula in Uganda: A Qualitative Study
    (Global public health, 2023-09-06) El Ayadi, Alison M.; Nalubwama, Hadija; Semere, Wagahta; Barageine, Justus K.; Obore, Susan; Lucas, Ruby; Byamugisha, Josaphat
    This study aimed to explore the firsthand experiences of informal primary caregivers of women with female genital fistula in Uganda. Caregivers that accompanied women for surgery at Mulago National Teaching and Referral Hospital were recruited between January and September 2015. Caregivers participated in in-depth interviews and focus groups. Data were analysed thematically and informed adaptation of a conceptual framework. Of 43 caregivers, 84% were female, 95% family members, and most married and formally employed. Caregivers engaged in myriad personal care and household responsibilities, and described being on call for an average of 22.5 h per day. Four overlapping themes emerged highlighting social, economic, emotional, and physical experiences/consequences. The caregiving experience was informed by specific caregiver circumstances (e.g. personal characteristics, care needs of their patient) and dynamic stressors/supports within the caregiver’s social context. These results demonstrate that caregivers’ lived social, economic, emotional, and physical experiences and consequences are influenced by both social factors and individual characteristics of both the caregiver and their patient. This study may inform programmes and policies that increase caregiving supports while mitigating caregiving stressors to enhance the caregiving experience, and ultimately ensure its feasibility, particularly in settings with constrained resources.

We recruited a 60-woman longitudinal cohort at surgical hospitalisation from Mulago Hospital in Kampala Uganda (Dec 2014–June 2015) and followed them for 1 year. We collected survey data on physical and psychosocial health at surgery and at 3, 6, 9 and 12 months via mobile phone. Fistula characteristics were abstracted from medical records. All participants provided written informed consent. We present univariate analysis and linear regression results. Across post-surgical follow-up, most women reported improvements in physical and psychosocial health, largely within the first 6 months. By 12 months, urinary incontinence had declined from 98% to 33% and general weakness from 33% to 17%, while excellent to good general health rose from 0% to 60%. Reintegration, self-esteem and quality of life all increased through 6 months and remained stable thereafter. Reported stigma reduced, yet some negative self-perception remained at 12 months (mean 17.8). Psychosocial health was significantly impacted by the report of physical symptoms; at 12 months, physical symptoms were associated with a 21.9 lower mean reintegration score (95% CI −30.1, −12.4). Our longitudinal cohort experienced dramatic improvements in physical and psychosocial health after surgery. Continuing fistula-related symptoms and the substantial differences in psychosocial health by physical symptoms support additional intervention to support women's recovery or more targeted psychosocial support and reintegration services to ensure that those coping with physical or psychosocial challenges are appropriately supported.

    Toward defining the preclinical stages of Alzheimer’s disease: Recommendations from the National Institute on Aging-Alzheimer’s Association workgroups on diagnostic guidelines for Alzheimer’s disease
    (Alzheimer's & dementia, 2011-05-14) Sperling, Reisa A.; Bennett, David A.; Iwatsubo, Takeshi; Kaye, Jeffrey; Montine, Thomas J.; Yaffe, Kristine; Phelps, Creighton H.
    The pathophysiological process of Alzheimer’s disease (AD) is thought to begin many years before the diagnosis of AD dementia. This long “preclinical” phase of AD would provide a critical opportunity for therapeutic intervention; however, we need to further elucidate the link between the pathological cascade of AD and the emergence of clinical symptoms. The National Institute on Aging and the Alzheimer’s Association convened an international workgroup to review the biomarker, epidemiological, and neuropsychological evidence, and to develop recommendations to determine the factors which best predict the risk of progression from “normal” cognition to mild cognitive impairment and AD dementia. We propose a conceptual framework and operational research criteria, based on the prevailing scientific evidence to date, to test and refine these models with longitudinal clinical research studies. These recommendations are solely intended for research purposes and do not have any clinical implications at this time. It is hoped that these recommendations will provide a common rubric to advance the study of preclinical AD, and ultimately, aid the field in moving toward earlier intervention at a stage of AD when some disease-modifying therapies may be most efficacious.

    International Consensus Guidelines for the Optimal Use of the Polymyxins: Endorsed by the American College of Clinical Pharmacy (ACCP), European Society of Clinical Microbiology and Infectious Diseases (ESCMID), Infectious Diseases Society of America (IDSA), International Society for Antiinfective Pharmacology (ISAP), Society of Critical Care Medicine (SCCM), and Society of Infectious Diseases Pharmacists (SIDP)

    The polymyxin antibiotics colistin (polymyxin E) and polymyxin B became available in the 1950s and thus did not undergo contemporary drug development procedures. Their clinical use has recently resurged, assuming an important role as salvage therapy for otherwise untreatable gram-negative infections. Since their reintroduction into the clinic, significant confusion remains due to the existence of several different conventions used to describe doses of the polymyxins, differences in their formulations, outdated product information, and uncertainties about susceptibility testing that has led to lack of clarity on how to optimally utilize and dose colistin and polymyxin B. We report consensus therapeutic guidelines for agent selection and dosing of the polymyxin antibiotics for optimal use in adult patients, as endorsed by the American College of Clinical Pharmacy (ACCP), Infectious Diseases Society of America (IDSA), International Society of Anti-Infective Pharmacology (ISAP), Society for Critical Care Medicine (SCCM), and Society of Infectious Diseases Pharmacists (SIDP). The European Society for Clinical Microbiology and Infectious Diseases (ESCMID) endorses this document as a consensus statement. The overall conclusions in the document are endorsed by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). We established a diverse international expert panel to make therapeutic recommendations regarding the pharmacokinetic and pharmacodynamic properties of the drugs and pharmacokinetic targets, polymyxin agent selection, dosing, dosage adjustment and monitoring of colistin and polymyxin B, use of polymyxin-based combination therapy, intrathecal therapy, inhalation therapy, toxicity, and prevention of renal failure. The treatment guidelines provide the first ever consensus recommendations for colistin and polymyxin B therapy that are intended to guide optimal clinical use.

    The landscape of somatic copy-number alteration across human cancers
    (Nature, 2010-02-18) Beroukhim, Rameen; Raychaudhuri, Soumya; Tanaka, Kumiko E.; Kaye, Frederic J.; Ladanyi, Marc; Okamoto, Aikou; Meyerson, Matthew
    A powerful way to discover key genes with causal roles in oncogenesis is to identify genomic regions that undergo frequent alteration in human cancers. Here we present high-resolution analyses of somatic copy-number alterations (SCNAs) from 3,131 cancer specimens, belonging largely to 26 histological types. We identify 158 regions of focal SCNA that are altered at significant frequency across several cancer types, of which 122 cannot be explained by the presence of a known cancer target gene located within these regions. Several gene families are enriched among these regions of focal SCNA, including the BCL2 family of apoptosis regulators and the NF-κΒ pathway. We show that cancer cells containing amplifications surrounding the MCL1 and BCL2L1 anti-apoptotic genes depend on the expression of these genes for survival. Finally, we demonstrate that a large majority of SCNAs identified in individual cancer types are present in several cancer types.
