Prevalence of Malaria Among Individuals Living With Lymphedema in Kamwenge District, Western Uganda
(Springer Nature, 2025-10-02) Mwesigye, Vicent; Tebulwa, Joanita Berytah; Musinguzi, Benson; Muzafaru, Twinomujuni; Zamarano, Henry; Bagenda, Charles Nkubi; Mulogo, Edgar; Byarugaba, Frederick; Herbert, Itabangi
Lymphedema, also known as elephantiasis, is a long-term and often debilitating condition characterized by the progressive swelling of limbs due to poor lymphatic drainage. While lymphatic filariasis, a mosquito-borne disease, is a common infectious cause globally, non-infectious forms such as podoconiosis resulting from prolonged exposure to mineral-rich soils are also prevalent in many low-resource, endemic regions. In areas where both malaria and lymphedema occur, malaria may further affect individuals already suffering from chronic swelling. In Kamwenge District, Western Uganda, lymphedema is a recognized public health concern, yet the contributing factors remain poorly understood. This lack of clarity complicates effective diagnosis, treatment, and disease control. This study aimed to assess the presence of malaria among individuals living with lymphedema in this setting.
A cross-sectional study was conducted among 154 individuals with clinically confirmed lymphedema, recruited through purposive sampling from Rukunyu Hospital and surrounding communities. Data collection involved structured interviews, physical examinations, and venous blood sampling. Malaria infection was determined through microscopic examination of blood smears.
Of the 154 participants, 71.4% were female, with an average age of 54.7 years. Plasmodium falciparum was detected in 3.3% (n=5) of the individuals. The majority (96.8%) had bilateral lower limb lymphedema and resided in rural areas, primarily engaged in subsistence farming.
The presence of malaria among individuals with lymphedema highlights the need for integrated healthcare approaches in areas where multiple parasitic diseases are endemic. Although malaria was detected in a small portion of participants, its occurrence alongside lymphedema underscores the importance of continued disease surveillance, targeted interventions, and community education to support affected populations.
Navigating the enigmas of unregulated nomadic pastoralism on peasant farmer communities
(East African Nature and Science Organization (EANSO), 2025-09-15) Ocan, Johnson; Eton, Marus; Akello, Jacqueline; Arinaitwe, Julius Alexander
This study investigated the profound implications of the roaming pastoral practices of the Balaalo on peasant farming communities in Northern Uganda, particularly the disruptions resulting from their free-range nomadic lifestyles. Employing a qualitative research design, data were collected through questionnaires and subsequently analysed using MAXQDA’s auto-coding, sentiment, and text-based analytical tools. The target population comprised 600 individuals across affected communities, with 400 participants ultimately completing the study. The reduced participation was largely attributed to the contextual challenges of unregulated pastoralism: seasonal cattle movements and recurrent land conflicts caused widespread displacement, insecurity, and mobility, which hindered consistent engagement. Furthermore, subsistence farmers often prioritised urgent survival activities over research commitments, making the final sample both realistic and representative of community realities. Findings reveal that loosely regulated mobile pastoralism exerts a significant strain on agrarian livelihoods. The Balaalo’s patterns of land encroachment and the destruction of farmlands have intensified tensions across the Acoli, Lango, and Madi subregions, with a high potential for replication in other parts of Uganda if left unaddressed. The study underscores the structural consequences of nomadic incursions, including disruption of local farming systems, heightened food insecurity, and increasing vulnerability among subsistence households. These dynamics highlight the urgent need for effective policy interventions to balance pastoral mobility with agrarian land rights. The study acknowledges certain limitations. Because the analysis draws on case studies within four districts, the findings cannot fully capture the breadth of livelihood adjustments or the nuanced belief systems of all affected communities. Nonetheless, the research provides valuable insights into ongoing structural transformations in northern Uganda. This work makes three critical contributions: first, it demonstrates the long-term consequences of unregulated pastoral mobility on smallholder farming systems; second, it highlights the formation of alternative and adaptive livelihood strategies within contested rangelands; and third, it situates these processes within broader debates on poverty reduction and vulnerability mitigation in pastoral–agrarian interfaces. By foregrounding the lived realities of farmers confronting the pressures of roaming pastoralism, the study advances both scholarly and policy dialogues on land use, livelihood security, and sustainable coexistence in Uganda and beyond.
Addressing stigma, mental well-being, and alcohol use among people with tuberculosis in Sub-Saharan Africa: A Call for an integrated care model
(American Society of Tropical Medicine and Hygiene (ASTMH), 2025-07-29) Izudi, Jonathan; Bajunirwe, Francis; Cattamanchi, Adithya; West, Nora
Tuberculosis (TB) remains a major public health challenge in sub-Saharan Africa (SSA), with stigma, mental health issues, and alcohol use significantly affecting treatment outcomes. Stigma delays TB diagnosis, reduces treatment adherence, and disrupts care continuity. Mental health conditions, such as depression and anxiety, further undermine adherence, whereas alcohol use accelerates TB disease progression and leads to poor treatment outcomes. Current TB care models in SSA lack integrated support for psychosocial and behavioral health needs. This article advocates for a comprehensive care model that integrates mental health screening, counseling, psychosocial support, alcohol use disorder screening, and harm reduction strategies into TB programs. Effective implementation requires collaboration among TB care providers, mental health specialists, and alcohol use counselors supported by research, provider training, and community engagement. By addressing stigma, mental health, and alcohol use, this model can enhance treatment adherence and outcomes, advancing the WHO’s End TB Strategy in SSA.
Acute and sub-acute toxicity assessment of methanolic stem bark extract of Khaya anthotheca (Meliaceae) in Wistar rats
(Springer Nature, 2025-08-29) Akwongo, Betty; Kakudidi, Esezah K.; Nsubuga, Anthony M.; Andama, Morgan; Namaganda, Mary; Tugume, Patience; Asiimwe, Savina; Anywar, Godwin; Katuura, Esther
Background: Khaya anthotheca (Meliaceae) is a medicinal plant with a wide range of therapeutic properties attributable mainly to the diverse limonoids it contains. Different parts of the plant are used in traditional health care for treatment of various diseases including candidiasis. However, inadequate information on its safety prompted this particular study.
Methods: Acute toxicity was assessed according to OECD guidelines 425 in female rats administered with single oral doses of 2000 and 5000 mg/kg body weight (b.wt), and monitored for 14 days for any sign of toxicity and mortality. Sub-acute toxicity was evaluated in both male and female rats following OECD guideline 407, and were administered with extract doses of 500, 250 and 125 mg/kg b.wt repeatedly for 28 days. Body weights were measured weekly, while food and water intake were measured daily. Blood for biochemistry, hematology, and organs for histopathology were collected at the end of the experimental period. Data were analyzed using one-way ANOVA followed by Turkey’s post hoc tests, and repeated measures ANOVA.
Results: Acute toxicity showed no mortality, with half-lethal dose (LD50) being greater than 5000 mg/kg b.wt. For sub-acute toxicity, both male and female rats presented significant increase in food and water consumption, increased body weight with increasing time and extract doses (p < 0.05). The 500 mg/kg dosed female rats showed significant increase in stomach weights and alanine aminotransferase (ALT), while renal function marker of chloride ions (Cl−) decreased. Male rats showed dose-dependent significant rise in albumin (ALB) (p = 0.024). For both male and female rats, prolonged use of high extract doses of 250 and 500 mg/kg b.wt for 28 days were toxic to the stomach and liver.
Conclusions: The methanolic stem bark extract of K. anthotheca is practically non-toxic at acute dose of 5000 mg/kg b.wt, and safe for clinical use at low sub-acute doses of 125 mg/kg b.wt. However, long-term administration of high extract doses above 125 mg/kg was toxic to mainly the liver and stomach. Thus, long-term administration of high dosage of methanol stem bark extract of K. anthotheca, and phytomedicine development should be done with cautions of potential side effects.

Background
The emergence of multidrug resistant Candida species to available drugs has led to renewed interest in the use of herbal medicines globally. This study scientifically verified antifungal effectiveness of five commonly used plant species in Pader district, against selected pathogenic candida strains.
Methods
Powdered roots of Momordica foetida, Sansevieria dawei and Distimake dissectus; and stem barks of Khaya anthotheca and Mitragyna rubrostipulata were extracted sequentially using petroleum ether and methanol, respectively; and total water extraction at 24.4 °C (maceration), 60 °C (decoction) and boiling water at 87 °C (hot water infusion). Extracts and their combinations, positive controls (amphotericin B, and fluconazole) and negative control (80% dimethyl sulfoxide, verified to be tolerable concentration to the tested Candida species) were screened and verified for their antifungal activity against Candida albicans (ATCC: American Type Culture Collection reference strain 10231, ATCC 90028, 0770a and 0796), C. glabrata (VVc 004, ATCC 2950) and C. tropicalis (ATCC 750 and 0210) using agar well diffusion and broth micro-dilution, respectively.
Results
Aqueous extract (24.4 °C) of M. rubrostipulata (ZOI: 18.00 ± 1.00 to 38.33 ± 0.17; MIC: 3.13 ± 0.00 to 20.83 ± 4.17; MFC: 12.50 ± 0.00 to 200.00 ± 0.00), methanol extract of K. anthotheca (10.11 ± 0.31 to 15.11 ± 0.65; 1.04 ± 0.26 to 12.50 ± 0.00; 12.50 ± 0.00 to 100.00 ± 0.00), and combination of aqueous extract (60 °C) of D. dissectus + methanol extract of K. anthotheca (7.89 ± 0.26 to 19.67 ± 0.37; 0.78 ± 0.00 to 50.00 ± 0.00; 12.50 ± 0.00 to 200.00 ± 0.00) exhibited broad spectrum antifungal activities and were fungistatic against all tested Candida species, which comprised 8 clinical/control and susceptible/resistant strains. None of the conventional drugs used demonstrated broad spectrum antifungal activity across all tested Candida species/strains.
Conclusion
Methanol extract of K. anthotheca, aqueous extract (24.4 °C) of M. rubrostipulata, and combination of aqueous extract (60 °C) of D. dissectus + methanol extract of K. anthotheca could be effective in the treatment of candidiasis. They demonstrated potential broad spectrum antifungal activity against different species and strains of tested Candida than the fluconazole and amphotericin B drugs. Their fungistatic nature showed their ability to inhibit fungal growth. Hence, these extracts/extract combination can offer better treatment option for candidiasis if they are standardized and also their active curative compounds isolated and made into antifungal drugs.
