    Antimalarial Combination Therapies Increase Gastric Ulcers through an Imbalance of Basic Antioxidative-Oxidative Enzymes in Male Wistar Rats
    (BMC Research Notes, 2020) Kalange, Muhamudu; Nansunga, Miriam; Kasozi, Keneth Iceland; Kasolo, Josephine; Namulema, Jackline; Atusiimirwe, Jovile Kasande; Ayikobua, Emmanuel Tiyo
    Antimalarials are globally used against plasmodium infections, however, information on the safety of new antimalarial combination therapies on the gastric mucosa is scarce. The aim of this study was to investigate the effects of Artesunate-Amodiaquine and Artemether-Lumefantrine on ulcer induction. Malondialdehyde (MDA), reduced glutathione (GSH) and major histological changes in male Wistar rats following ulcer induction using Indomethacin were investigated. Gastric ulcers were in four groups; Group I was administered Artesunate, group II received Artesunate-Amodiaquine, group III received Artemether-Lumefantrine, and group IV was a positive control (normal saline). Group V was the negative control consisting of healthy rats.Antimalarial combination therapies were associated with a high gastric ulcer index than a single antimalarial agent, Artesunate. In addition, levels of MDA were significantly higher in the combination of therapies while levels of GSH were lower in comparison to Artesunate and the negative control. Microscopically, antimalarial combination therapies were associated with severe inflammation and tissue damage than Artesunate in the gastric mucosa showing that antimalarial combination therapies exert their toxic effects through oxidative stress mechanisms, and this leads to cellular damage. Findings in this study demonstrate a need to revisit information on the pharmacodynamics of major circulating antimalarial agents in developing countries.

    Embracing One Health offers practical strategies in management of COVID-19 for Africa
    (The Pan African Medical Journal, 2020) Kasozi, Keneth Iceland; Mujinya, Regan; Bogere, Paul; Ekou, Justine; Zirintunda, Gerald; Ahimbisibwe, Salaviriuse; Matama, Kevin; Ninsiima, Herbert Izo; Ayikobua, Emmanuel Tiyo; Ssimbwa, Godfrey; Musinguzi, Simon Peter; Muyinda, Robert; Ssempijja, Fred; Matovu, Henry; MacLeod, Ewan; Anderson, Neil Euan; Welburn, Susan Christina
    The coronavirus, COVID-19 outbreak has now affected over 60% of African countries in less than two months , gaining a foothold through major economic and transport hubs on the African continent including Egypt, Algeria, Nigeria, South Africa and Kenya. Travel restrictions imposed against citizens from countries with major outbreaks including China, USA and those in Europe were too late . African Union member states as of early April 2020 are reporting 6,470 cases and 241 deaths from COVID-19 reporting growth as “close to exponential”. Africa Centers for Disease Control and Prevention acknowledges the virus is an existential threat to African countries and that with local transmission now underway many would pass the 10,000-infection mark by the end of April. While the impact of wearing of face masks for control of COVID-19 remains controversial, it is inarguable that respiratory transmission needs to be prevented. Currently, there is a global shortage of masks and personal protective equipment (PPE) and distribution is being rationed in developed countries to retain this for workers in the health system, showing that developing countries in Africa are bound to suffer more should the pandemic be mismanaged at these early stages. In addition, health systems in developing countries, already crippled from years of underinvestment will be compromised unless practical and realistic prevention strategies are put in place. China, Italy, France, UK and USA, all with sophisticated health systems, have found COVID-19 challenging. Infection is increasing across the African subcontinent and health systems will struggle as the pandemic sweeps into and across Africa.

    Synergistic action of propolis with levodopa in the management of Parkinsonism in Drosophila melanogaster
    (Journal of Complementary and Integrative Medicine, 2020) Ayikobua, Emmanuel Tiyo; Kasolo, Josephine; Kasozi, Keneth Iceland; Eze, Ejike Daniel; Safiriyu, Abass; Ninsiima, Herbert Izo; Kiyimba, Kennedy; Namulema, Jackline; Jjesero, Edward; Ssempijja, Fred; Semuyaba, Ibrahim; Kimanje, Kyobe Ronald; Kalange, Muhamudu; Okpanachi, Alfred Omachonu; Nansunga, Miriam
    The Phosphatase and tensin-induced putative kinase 1 (PINK1B9) mutant for Drosophila melanogaster is a key tool that has been used in assessing the pathology of Parkinsonism and its possible remedy. This research was targeted toward determining the effects of ethanolic extract of propolis, with levodopa therapy in the management of Parkinsonism. The PINK1B9 flies were divided into groups and fed with the different treatment doses of ethanoic extract of propolis. The treatment groups were subjected to 21 days of administration of propolis and the levodopa at different doses after which percentage climbing index, antioxidant activity and lifespan studies were done.Propolis alone improved motor activity, antioxidant and lifespan in Drosophila melanogaster than in PINK1 flies. Propolis in combination with levodopa significantly (P<0.05) improved physiological parameters at higher than lower concentrations in Parkinsonism Drosophila melanogaster demonstrating its importance in managing side effects associated with levodopa. Propolis is a novel candidate as an alternative and integrative medicinal option to use in the management of Parkinsonism in both animals and humans at higher concentrations.

    University Lecturers and Students Could Help in Community Education about SARS-CoV-2 Infection in Uganda
    (Health services insights, 2020) Echoru, Isaac; Kasozi, Keneth Iceland; Usman, Ibe Michael; Mutuku, Irene Mukenya; Ssebuufu, Robinson; Ajambo, Patricia Decanar; Ssempijja, Fred; Mujinya, Regan; Matama, Kevin; Musoke, Grace Henry; Ayikobua, Emmanuel Tiyo; Ninsiima, Herbert Izo; Dare, Samuel Sunday; Eze, Ejike Daniel; Bukenya, Edmund Eriya; Nambatya, Grace Keyune; MacLeod, Ewan; Welburn, Susan Christina
    The World Health Organization has placed a lot of attention on vulnerable communities of Africa due to their chronically weak health care systems. Recent findings from Uganda show that medical staff members have sufficient knowledge but poor attitudes toward coronavirus disease 2019 (COVID-19) pandemic.The aim of this study was to determine the knowledge, attitudes, and preparedness/practices of lecturers and students in the fight against COVID-19.This was a descriptive cross-sectional study of 103 lecturers and students both men and women of age group 18 to 69 years in western Uganda. Data were obtained through a pretested questionnaire availed online.Knowledge on COVID-19 symptoms was highest in this order: fever > dry cough > difficulty breathing > fatigue > headache with no significant differences between lecturers and students. Knowledge of participants on transmission of COVID-19 was highest in the order of cough drops > contaminated surfaces > person-to-person contact > asymptomatic persons > airborne > zoonotic with no significant differences among lecturers and students. Lecturers and students were all willing to continue using personal protective equipment like masks, and personal practices such as covering the mouth while sneezing and coughing, no handshaking, and washing of hands with no significant differences in the responses. The positive attitudes that COVID-19 could kill, anyone can get COVID-19, and willing to abide by the set regulations against the pandemic showed personal concerns and desired efforts against COVID-19.The study identifies lecturers and students as potential stakeholders in the fight against community transmission of COVID-19.
