    (BioMed Central Ltd, 2024-04-15) Namwase, Shamiim; Ruvuma, Sam; Onyango, John; Kwaga, Teddy; Ebong, Abel; Atwine, Daniel; Mukunya, David; Arunga, Simon
    Background To assess the prevalence of low corneal endothelial cell density and correlates of corneal endothelial cell density among adults attending Mbarara University and Referral Hospital Eye Centre in Uganda. Methods In this hospital-based cross-sectional study, participants 18 years and older, were enrolled. We obtained informed consent, and basic demographic data. We also conducted visual acuity, a detailed slit lamp examination, intra-ocular pressure, corneal diameter, tear-film break-up time, keratometry, A-scan, and pachymetry on all participants. A confocal microscope Heidelberg HRT3 was used to examine the central cornea and to obtain the mean cell density (cells/mm.sup.2). To calculate the proportion of low endothelial cell density, descriptive statistics were used, whereas correlates of endothelial cell density were assessed, using linear regression analyses. Results We evaluated a total of 798 eyes of 404 participants aged between 18 and 90 years (males = 187, females = 217). The average endothelial cell density was 2763.6 cells/mm.sup.2, and there was a decrease in endothelial cell density with increasing age, irrespective of gender. There was no significant difference in endothelial cell density between males and females. Increasing age (adjusted coefficient - 10.1, p < 0.001), history of smoking (adjusted coefficient - 439.6, p = 0.004), history of ocular surgery (adjusted coefficient - 168.0, p = 0.023), having dry eye (adjusted coefficient - 136.0, p = 0.051), and having arcus senilis (adjusted coefficient - 132.0, p = 0.08), were correlated with lower endothelial cell density. However, increasing corneal diameter (adjusted coefficient 134.0, p = 0.006), increasing central corneal thickness (adjusted coefficient 1.2, p = 0.058), and increasing axial length (adjusted coefficient 65.8, p = 0.026), were correlated with higher endothelial cell density. We found five eyes (0.63%) from different participants with a low endothelial cell density (< 1000cells/mm.sup.2). Conclusion Our study established baseline normal ranges of ECD in a predominantly black African population, and found that low ECD is rare in our population. The elderly, smokers, and those with past ocular surgery are the most vulnerable. The low prevalence could be due to a lack of reference values for the black African population.

    Enhancing the implementation and integration of mHealth interventions in resource-limited settings: a scoping review
    (BioMed Central Ltd, 2024-10) Tumuhimbise, Wilson; Theuring, Stefanie; Kaggwa, Fred; Atukunda, Esther C; Rubaihayo, John; Atwine, Daniel; Sekandi, Juliet N; Musiimenta, Angella
    Although mobile health (mHealth) interventions have shown promise in improving health outcomes, most of them rarely translate to scale. Prevailing mHealth studies are largely small-sized, short-term and donor-funded pilot studies with limited evidence on their effectiveness. To facilitate scale-up, several frameworks have been proposed to enhance the generic implementation of health interventions. However, there is a lack of a specific focus on the implementation and integration of mHealth interventions in routine care in low-resource settings. Our scoping review aimed to synthesize and develop a framework that could guide the implementation and integration of mHealth interventions. We searched the PubMed, Google Scholar, and ScienceDirect databases for published theories, models, and frameworks related to the implementation and integration of clinical interventions from 1st January 2000 to 31st December 2023. The data processing was guided by a scoping review methodology proposed by Arksey and O'Malley. Studies were included if they were i) peer-reviewed and published between 2000 and 2023, ii) explicitly described a framework for clinical intervention implementation and integration, or iii) available in full text and published in English. We integrated different domains and constructs from the reviewed frameworks to develop a new framework for implementing and integrating mHealth interventions. We identified eight eligible papers with eight frameworks composed of 102 implementation domains. None of the identified frameworks were specific to the integration of mHealth interventions in low-resource settings. Two constructs (skill impartation and intervention awareness) related to the training domain, four constructs (technical and logistical support, identifying committed staff, supervision, and redesigning) from the restructuring domain, two constructs (monetary incentives and nonmonetary incentives) from the incentivize domain, two constructs (organizational mandates and government mandates) from the mandate domain and two constructs (collaboration and routine workflows) from the integrate domain. Therefore, a new framework that outlines five main domains-train, restructure, incentivize, mandate, and integrate (TRIMI)-in relation to the integration and implementation of mHealth interventions in low-resource settings emerged. The TRIMI framework presents a realistic and realizable solution for the implementation and integration deficits of mHealth interventions in low-resource settings. MEDLINE

    Household costs incurred under community- and facility-based service-delivery models of tuberculosis preventive therapy for children: a survey in Cameroon and Uganda
    (Inishmore Laser Scientific Publishing Ltd, 2023-11) Mafirakureva, Nyashadzaishe; Mukherjee, Sushant; Tchounga, Boris; Atwine, Daniel; Tchakounte Youngui, Boris; Ssekyanzi, Bob; Okello, Richard; Leonie, Simo; Cohn, Jennifer; Casenghi, Martina; Vasiliu, Anca; Bonnet, Maryline; Dodd, Peter J
    Abstract Background Tuberculosis preventive treatment (TPT) in child household contacts is recommended by World Health Organization (WHO) but limited data has been reported on the costs experienced by households with children receiving TPT. Methods We evaluated the economic impact on households with children receiving TPT within a service-delivery model cluster-randomised controlled trial in Cameroon and Uganda. The intervention included community health worker-led home-based child-contact screening, TPT initiation and monitoring, and referral of children with presumptive tuberculosis or side effects, and was compared with each country’s facility-based standard of care (control). We used a retrospective cross-sectional survey adapted from the WHO Global task force on tuberculosis patient cost surveys. All costs were collected between February 2021 and March 2021 and are presented in 2021 US$. Results The median household costs estimated using the human capital approach were higher in the control arm ($62.96 [interquartile range, IQR; $19.78-239.74] in Cameroon and $35.95 [IQR; $29.03-91.26] in Uganda) compared to the intervention arm ($2.73 [IQR; $2.73-14.18] in Cameroon and $4.55 [IQR; $3.03-6.06] in Uganda). Using a threshold of 20% of annual household income, 15% (95%CI; 5-31%) of households in Cameroon and 14% (95%CI; 4-26%) in Uganda experienced catastrophic costs in the control compared to 3% (95%CI; 1- 8%) in Cameroon and 3% (95%CI; 1-8%) in Uganda in the intervention. Using the output-based approach to estimate income losses increased costs by 14-32% in the control and 13-19% in the intervention across the two countries. The proportion of participants experiencing any dissaving was higher in the control, 53% (95%CI; 36-71%) in Cameroon and 50% (95%CI; 31-69%) in Uganda, compared to 18% (95%CI; 10-29%) in Cameroon and 17% (95%CI; 8-28%) in Uganda in the intervention. Conclusions Households with child contacts initiated on TPT under a facility-based model incur significant costs. Community-based interventions help to reduce these costs but do not eliminate catastrophic expenditures. Registration https://clinicaltrials.gov/ct2/show/NCT03832023.

    Non-disclosure of tuberculosis diagnosis by patients to their household members in south western Uganda
    (PloS one, 2020) Nyangoma, Miria; Bajunirwe, Francis; Atwine, Daniel
    Tuberculosis (TB) non-disclosure by adult patients to all household members is a setback to TB control efforts. It reduces the likelihood that household contacts will seek early TB screening, initiation on preventive or curative treatment, but also hinders the implementation of infection controls and home-based directly observed treatment. Therefore, the purpose of this study was to determine the level of TB non-disclosure, its predictors and the effects of disclosure among adult TB patients in Uganda.We conducted a cross-sectional study at a large regional referral hospital in Mbarara, south-western Uganda. Questionnaires were administered to collect patients’ sociodemographic and their TB disclosure data. Non-disclosure was considered if a patient did not reveal their TB diagnosis to all household members within 2 weeks post-treatment initiation. Univariate and multivariate logistic regression models were fitted for predictors of non-disclosure.We enrolled 62 patients, 74% males, mean age of 32 years, and median of five people per household. Non-disclosure rate was 30.6%. Post-disclosure experiences were positive in 98.3% of patients, while negative experiences suggestive of severe stigma occurred in 12.3% of patients. Being female (OR 6.5, 95% CI: 1.4–29.3) and belonging to Muslim faith (OR 12.4, 95% CI: 1.42–109.1) were significantly associated with TB non-disclosure to household members.There is a high rate of TB non-disclosure to all household members by adult patients in rural Uganda, particularly among women and muslim patients. Interventions enhancing TB disclosure at household level while minimizing negative effects of stigma should be developed and prioritized.

    Prevalence of depressive symptoms and associated factors among adolescents living with HIV/AIDS in South Western Uganda
    (AIDS care, 2019) Kemigisha, Elizabeth; Zanoni, Brian; Bruce, Katharine; Menjivar, Ricardo; Kadengye, Damazo; Atwine, Daniel; Rukundo, Godfrey Z.
    Adolescents living with HIV (ALHIV) are prone to depression, which can have detrimental effects including disease progression, poor treatment adherence and mortality. We aimed to determine the prevalence of depressive symptoms and their associated factors among ALHIV in Uganda. We conducted a cross-sectional survey among ALHIV (10–19 years) attending urban and rural clinics in Mbarara, Uganda between March and May 2017. Presence of depressive symptoms was assessed using the Centre for Epidemiological Studies’ Depression scale. We interviewed 336 adolescents with a median age of 13 years, 62% of whom were female. A third (37%) had disclosed their HIV/AIDS status and 13% were sexually active. Overall, 154 (∼46%, [95% CI: 40.5– 51.2]) had depressive symptoms. On bivariate analysis, the odds of having depressive symptoms were higher among adolescents who were ≥ 15 years, had disclosed HIV status, traveled >30 min for routine care and had risky sexual practices. On multiple variable analysis, only travel time to the clinic of >30 min was independently associated with depressive symptoms (AOR = 1.6 [95% CI: 1.02–2.7]). With the high prevalence of depressive symptoms among ALHIV in Uganda, screening and prompt treatment of depression should be incorporated within their routine care.
