Antiretroviral therapy (ART) restores cellular immunity, significantly reducing AIDS-related mortality and morbidity thus improving the quality of life among People living with HIV (PLHIV). Studies done in several countries show a decline in AIDS defining cancers (ADCs) with the introduction of ART however the increased longevity has led to the increase of Non-AIDS defining cancers (NADCs). The study was aimed at studying the changing spectrum and trends of cancer among Human Immunodeficiency Virus (HIV) patients in southwestern Uganda.
The study was a retrospective chart review of records of HIV-positive patients attending/receiving care from the Oncology clinic and ISS clinic of Mbarara Regional Referral Hospital (MRRH) who were, diagnosed with cancer for the past 10 years (January 2012-2021). Data were statistically analyzed using STATA version 17 (Stata Corp, Texas, US) at P < 0.05.
Males were more common at 64.5% while the median age was 37 years (IQR 29-47 years). ADCs were seen in 77.5% of the population while participants with NADCs were older (p < 0.001). The majority 73.3% (283/386) were in later stages (3 and 4). Having either ADCs or NADCs was different across HIV stages (p < 0.001). The median baseline CD4 count was 205 cells/μl (IQR: 90-400 cells/μl). The median duration on ART was 15 months (IQR 3-65 months). Participants with ADCs had been on ART for a shorter duration of time (p < 0.001). Only the outcome of patients with ADCs were available. The outcome varied with sex (p < 0.036), baseline CD4 (p < 0.048), and HIV stage (p < 0.002). Males were more likely to die (30/38 or 78.95%) and lost to follow-up (26/41 or 60.98%). Participants with baseline CD4 cell count > 200 cells/μl were more than twice likely to be active in care. The Commonest ADC was Kaposi Sarcoma (KS) while the commonest NADC was Squamous cell carcinoma, Not otherwise specified. Age above 50 years was associated with a significantly reduced risk of ADCs (OR: 0.11; 95% CI: 0.03-0.43; p value: 0.002). The risk of ADCs increased from stage 2 (OR: 0.46, p-value: 0.03; 95% CI: 0.23-0.91) to stage 3 (OR: 1.13; p-value: 0.66; 95% CI: 0.65-1.97) but this was not statistically significant. The risk of ADCs decreased with increasing ART duration (P value < 0.05).
ADCs are still a major health challenge in Southwestern Uganda despite the increasing the coverage and uptake of ART in region. These have mostly affected the young people, people who have been on HAART for a shorter period and those with lower CD4 cell count at initiation of ART.

In this perspective review, we describe a brief background on the status quo of diabetes mellitus-related therapies and glycemic control among patients in rural communities in sub-Saharan Africa. The article discusses insulin therapy as well as the difficulties in obtaining insulin and oral hypoglycemic medications for diabetic patients living in sub-Saharan Africa. We wrap up our discussion with suggestions on solutions and opportunities for future research to tackle this health challenge in these impoverished communities. We conducted a literature search from PubMed and Google Scholar up until August 2023. Key words were used to generate search terms used to retrieve the required information. All types of literature with pertinent information on the current topic were included in the study. Diabetes mellitus is on the rise in sub-Saharan Africa. Several studies have reported poor glycemic control, low screening rates for diabetes mellitus, cigarette smoking, high alcohol consumption, prescription of antidiabetic therapy, and associated costs as contributors to the uptake of antidiabetic treatment. Although there is paucity of data on the extent of insulin therapy uptake and its possible modifiable contributors among the diabetic patients in the region, the anticipated increase in the number of people with diabetes on the continent makes it critical for global leaders to address the research gaps in insulin therapy among rural communities of sub-Saharan Africa, thus reducing the burden of diabetes in these populations.

Background
In Sub-Saharan Africa, the prevalence of dyslipidemia is on the rise, with studies showing dyslipidemia as a contributing factor to the progression of premalignant lesions to cervical cancer. In Uganda, cervical cancer and dyslipidemia are common health concerns, considering the increasing trends of dyslipidemia in the general population and inadequate information regarding dyslipidemia and cervical lesions. This study aimed to determine the prevalence of dyslipidemia and its association with precancerous and cancerous lesions of the cervix among women attending a cervical cancer clinic at the Uganda Cancer Institute.
Methods
This cross-sectional study was conducted from February to April 2022 among women with premalignant and malignant lesions of the cervix. Data on social demographics and health-seeking behaviours were collected using a pretested structured questionnaire after written informed consent had been obtained. Pap smear collection preceded visual inspection with acetic acid; cervical biopsies were collected appropriately from eligible participants; and cervical lesions were classified using the Bethesda system 2014. Serum lipids, total cholesterol (T.C.), high-density lipoprotein (HDLc), low-density lipoprotein (LDLc), and triglycerides (T.G.s) were analysed using the COBAS™ 6000 Clinical Chemistry Analyser. The associations were assessed using the chi-square test, and
P
≤ 0.05 was considered statistically significant.
Results
The overall prevalence of dyslipidemia among women with cervical lesions was 118/159 (74%), and low HDLc was the most prevalent at 64.6% (95% CI 39.0–54.3). High T.C. (
P
= 0.05), high T.G.s (
P
= 0.011), and low HDL-c (
P
= 0.05) showed a significant association with precancerous lesions. High LDL-c (
P
= 0.019), high T.G.s (
P
= 0.02), and high T.G.s (
P
< 0.001) showed a statistically significant association with cancerous lesions.
Conclusion
The prevalence of dyslipidemia was high, with high TC, T.G.s, and low HDL-c significantly associated with precancerous lesions. Also, elevated T.G.s and high LDLc were significantly associated with cancerous lesions. Women may benefit from dyslipidemia screening along with cervical cancer screening.
What this study adds
The present study builds upon previous findings suggesting a link between dyslipidemia and cervical lesions by investigating the relationship between these two factors, specifically in women of this geographical location, where we need adequate information on these associations.

A cross-sectional study of ERG expression and the relationship with clinicopathological features of Prostate cancer in Southwestern Uganda
2024
Background
Prostate cancer is the leading cause of cancer-related death and the second most commonly diagnosed cancer among men in Uganda and most countries in Sub-Saharan Africa (SSA). The TMPRSS2-ERG fusion gene is the most common genetic alteration seen among prostate cancer patients. There are several contradicting reports about the association of ERG protein with poor prognosis, high PSA, and Gleason score. This study determined the prevalence of ERG expression and the relationship with PSA, Gleason score, and Age of prostate cancer patients in Southwestern Uganda.
Methods
We reviewed 130 archived prostate biopsy (needle and TURP) specimens from patients of age ≥ 50 years who had a histological diagnosis of prostate cancer. We obtained their biodata, and preoperative PSA, from the archived records. We did Immunohistochemistry (IHC) to determine the prevalence of ERG expression.
Results
The mean patient age in our study was 74.64 ± 10.19 years. Pre-operative PSA levels had been done for 79.2% of the participants. Most cancers (58.46%) were of high grade (grade group 3–5). ERG expression prevalence was 75.4% and its expression was independent of age, re-operative PSA, and Gleason score.
Conclusion
There is a significantly higher prevalence of ERG expression in our study compared to what is reported in other African-based studies. The expression of the ERG is independent of age, Gleason score, and serum PSA levels. A high proportion of our prostate cancer has high-grade disease at the time of diagnosis.

Background
Population based cancer registries (PBCRs) are accepted as the gold standard for estimating cancer incidence in any population. However, only 15% of the world’s population is covered by high quality cancer registries with coverage as low as 1.9% in settings such as Africa. This study was conducted to assess the operational feasibility of estimating cancer incidence using a retrospective “catchment population” approach in Uganda.
Methods
A retrospective population study was conducted in 2018 to identify all newly diagnosed cancer cases between 2013 and 2017 in Mbarara district. Data were extracted from the medical records of health facilities within Mbarara and from national and regional centres that provide cancer care services. Cases were coded according to the International Classification of Diseases for Oncology (ICD-0-03). Data was analysed using CanReg5 and Excel.
Results
We sought to collect data from 30 health facilities serving Mbarara district, southwestern Uganda. Twenty-eight sources (93%) provided approval within the set period of two months. Among the twenty-eight sources, two were excluded, as they did not record addresses for cancer cases, leaving 26 sources (87%) valid for data collection. While 13% of the sources charged a fee, ranging from $30 to $100, administrative clearance and approval was at no cost in most (87%) data sources. This study registered 1,258 new cancer cases in Mbarara district. Of the registered cases, 65.4% had a morphologically verified diagnosis indicating relatively good quality of data. The Age-Standardised Incidence Rates for all cancers combined were 109.9 and 91.9 per 100,000 in males and females, respectively. In males, the most commonly diagnosed cancers were prostate, oesophagus, stomach, Kaposi’s sarcoma and liver. In females, the most common malignancies were cervix uteri, breast, stomach, liver and ovary. Approximately, 1 in 8 males and 1 in 10 females would develop cancer in Mbarara before the age of 75 years.
Conclusion
Estimating cancer incidence using a retrospective cohort design and a “catchment population approach” is feasible in Uganda. Periodic studies using this approach are potentially a precious resource for producing quality cancer data in settings where PBCRs are scarce. This could supplement PBCR data to provide a detailed and comprehensive picture of the cancer burden over time, facilitating the direction of cancer control efforts in resource-limited countries.

Background
In resource-limited settings like Uganda, managing HIV care through conventional paper-based systems poses challenges such as inefficiencies in clinical workflows and limited patient engagement. The AmFine patient portal and mobile application was developed to digitize the paper-based “blue card” system and enhance patient-provider communication.
Objective
To explore the lived experiences of patients and healthcare providers in using the AmFine patient portal and mobile application at the immune suppressive syndrome (ISS) Clinic of Mbarara Regional Referral Hospital, focusing on usability, motivation for use, challenges and suggestions for improvement.
Methods
We conducted face-to-face in-depth interviews with 25 participants (21 patients and 4 healthcare providers) at the ISS Clinic of Mbarara Regional Referral Hospital between April 2023 and May 2023. Interviews were audio-recorded, transcribed verbatim, and analyzed using codebook thematic analysis guided by Braun and Clarke's approach. Coding was conducted in NVivo 12, and themes were developed inductively to explore participant experiences, perceived usability, and challenges of the AmFine patient portal and mobile application.
Results
The AmFine patient portal and mobile application was positively perceived as enhancing communication and convenience. Patients appreciated the ability to send messages to providers without traveling to the clinic, fostering privacy and reducing stigma. Providers valued streamlined patient management and communication. Challenges included limited technological literacy among some patients, intermittent internet connectivity, and data costs. Suggestions for improvement included enhancing offline functionality, diversifying language options, and providing more detailed training sessions.
Conclusions
The AmFine patient portal and mobile application demonstrated potential to improve HIV care delivery and patient engagement in a resource-limited setting. Addressing identified challenges can optimize system usability and adoption.

2025
Alveolar Soft Part Sarcoma (ASPS) is a rare, highly vascular soft tissue sarcoma characterized by the specific ASPSCR1-TFE3 fusion, typically affecting adolescents and young adults. Despite its often-indolent growth, it has a high propensity for late hematogenous metastasis. Management for localized disease is centered on wide surgical excision.
We report a case of ASPS in a 44-year-old female from the Ankole tribe, presenting with a slow-growing 8 cm mass in her right upper arm over two years. This age of presentation is outside the typical peak incidence. The diagnosis was established solely on classic histopathological features-a pseudoalveolar pattern, large polygonal cells with abundant eosinophilic cytoplasm, and PAS-positive, diastase-resistant intracytoplasmic granules-due to resource limitations precluding molecular confirmation (TFE3 IHC/FISH). She underwent wide local excision with negative margins and remains free of recurrence at 12 months post-surgery.
This case highlights the occurrence of ASPS in an older-than-typical patient and underscores the enduring reliability of classic histopathology for definitive diagnosis in resource-limited settings like Uganda. Although surgically cured locally, the patient's large tumor size and age confer a high risk for future metastasis, mandating rigorous, long-term surveillance.

High Expression of WT1 and Low Expression of p53 in Archived Blocks of Children with Wilms Tumor in South Western Uganda
2024
The determination of the presence or absence of anaplasia in Wilms tumor is difficult sometimes creating diagnostic errors and is worsened by the use of neoadjuvant chemotherapy, which causes cellular alterations that may mimic anaplasia. This study described the histological features of Wilms tumor and their association with WT1 and p53 expression in archived specimens in South Western Uganda.
A series of 308 formalin-fixed paraffin-embedded tissue blocks belonging to 85 children were retrospectively recruited in the only public Histopathology laboratory in South Western Uganda. Rabbit monoclonal Anti-Wilms tumor protein antibody [(CAN-R9) IHC-56-2] ab89901 and rabbit monoclonal Anti-p53 antibody [E26] ab32389 were used to assess the expression of WT1 and p53, respectively. The expression of WT1 and p53 were reported as proportions, Chi-square was also performed to assess for associations and statistical significance was considered when the p-value was less than 0.05.
The median age was 3.5 with an interquartile range of (2-6) years. Mixed histology was the most common at 35.29% (95% CI:25.77-46.14). Anaplasia was present in 5.88% (95% CI:2.44-13.52) of the specimens. p53 and WT1 expressions were 13.0% (95% CI:7.25-22.04), and 41.0% (95% CI: 31.11-52.04), respectively.
Mixed-type histology is the most common histologic feature of Wilms tumor with high expression of WT1 and a low expression of p53 implying that these can be used routinely to confirm the diagnosis as well as anaplasia in South Western Uganda.

Case Report

Background
Schwannomas are benign, slow-growing tumors, primarily affecting the cervical and lumbar spine. When large, they may extend over multiple vertebral levels, posing surgical challenges. Spinal schwannomas are commonly encapsulated and extramedullary intradural tumors that rarely exhibit invasive characteristics.
Case presentation
A 13-year-old Ugandan Munyankore female patient, presented with a 6-year history of nontraumatic progressive quadriparesis, particularly in the lower limbs. Clinical examination showed power of 1/5 in the lower limbs, 4/5 in the upper limbs, hypertonia and hyperreflexia, with intact sensation, and no stigmata of neurofibromatosis. Magnetic resonance imaging revealed two “kissing” schwannomas extending from C2 to T2 in the cervical spine. Decompressive surgery was performed through laminoplasty and partial lesion resection, and histology confirmed schwannoma. Follow up of the patient showed stabilizing neurological status with noted improvement in lower limb strength.
Discussion
“Kissing” schwannomas are most frequently documented in the cerebellopontine angle, rarely in the spine, and even more rarely in children. While multiple schwannomas are often associated with Neurofibromatosis type 2, this case had no family history or clinical signs of the disorder and no genetic testing were done. Giant invasive spinal schwannomas (GISS) that span multiple vertebrae demand intricate surgical approaches owing to their proximity to neurovascular structures, though such procedure may require advanced technology, which is not available in low income countries.
Conclusion
This is one of the rarest reported cases of kissing cervical schwannomas in a young patient from a low-to-middle-income country. Surgical decompression, though challenging, is critical for neurological recovery in such advanced cases.

Uganda's public healthcare system faces significant systemic challenges in delivering care, contributing to poor health outcomes. In response, a North-South partnership between Massachusetts General Hospital (MGH), Mbarara University of Science and Technology (MUST), and Mbarara Regional Referral Hospital (MRRH) implemented the First Mile Project, a seven-year initiative (2018-2024) designed to strengthen the regional health system in southwestern Uganda. Guided by local priorities, the program aimed to improve access to care, enhance clinical capacity, expand medical education, and promote research and innovation. Project activities were devised collaboratively between investigators at MGH and MUST/MRRH, with robust local leadership and oversight. Key initiatives included clinical staffing in critical departments, construction of a regional isolation ward and oxygen plant. Additionally, the program provided scholarships for medical training, support for community-based care and continuing medical education, and provision of research and innovation grants. The program trained over 1500 health workers, supported 93 scholarships, increased access to specialized clinical services, and facilitated community outreach to thousands of households. The project also awarded 74 research grants and supported over 30 locally incubated innovations. Through this comprehensive, equity-focused approach, First Mile demonstrated how collaborative, locally driven partnerships can effectively strengthen health systems in low-resource settings. Lessons from the initiative underscore the importance of sustained local leadership and integrated clinical and research efforts. A 20-year history of collaboration and mutual trust ensured open dialogue between partners and helped support the success of the project. The First Mile model provides a promising example for future health system strengthening initiatives globally.
