Attenuation of Seizures, Cognitive Deficits, and Brain Histopathology by Phytochemicals of Imperata cylindrica (L.) P. Beauv (Poaceae) in Acute and Chronic Mutant Drosophila melanogaster Epilepsy Models.

Imperata cylindrica is a globally distributed plant known for its antiepileptic attributes, but there is a scarcity of robust evidence for its efficacy. The study investigated neuroprotective attributes of Imperata cylindrica root extract on neuropathological features of epilepsy in a Drosophila melanogaster mutant model of epilepsy. It was conducted on 10-day-old (at the initiation of study) male post-eclosion bang-senseless paralytic Drosophila (parabss1) involved acute (1-3 h) and chronic (6-18 days) experiments; n = 50 flies per group (convulsions tests); n = 100 flies per group (learning/memory tests and histological examination). Administrations were done in 1 g standard fly food, per os. The mutant flies of study (parabss1) showed marked age-dependent progressive brain neurodegeneration and axonal degeneration, significant (P < 0.05) bang sensitivity and convulsions, and cognitive deficits due to up-regulation of the paralytic gene in our mutants. The neuropathological findings were significantly (P < 0.05) alleviated in dose and duration-dependent fashions to near normal/normal after acute and chronic treatment with extract similar to sodium valproate. Therefore, para is expressed in neurons of brain tissues in our mutant flies to bring about epilepsy phenotypes and behaviors of the current juvenile and old-adult mutant D. melanogaster models of epilepsy. The herb exerts neuroprotection by anticonvulsant and antiepileptogenic mechanisms in mutant D. melanogaster due to plant flavonoids, polyphenols, and chromones (1 and 2) which exert antioxidative and receptor or voltage-gated sodium ion channels' inhibitory properties, and thus causing reduced inflammation and apoptosis, increased tissue repair, and improved cell biology in the brain of mutant flies. The methanol root extract provides anticonvulsant and antiepileptogenic medicinal values which protect epileptic D. melanogaster. Therefore, the herb should be advanced for more experimental and clinical studies to confirm its efficacy in treating epilepsy.

Behavioural Response To Self-Medication Practice Before and During Covid-19 Pandemic in Western Uganda.

Background: Self-medication has become a serious public health problem posing great risks, especially with the increasing number of cases of COVID-19 disease globally and in Uganda. This may be partly because of the absence of a recognized treatment for the disease, however, the differing prevalence and nature from country to country may influence human behavioral responses. Purpose: This study aimed to investigate the behavioral response to self-medication practices during the COVID-19 pandemic and lockdown in comparison to the pre-COVID period in Western Uganda. Methods: A descriptive cross-sectional survey was conducted from June to August 2020 in western Uganda using online Google forms and printed questionnaires to investigate the level of self-medication practice before and during the COVID-19 pandemic. This included 280 participants, aged 18 and above who consented to participate in the study. Participants were selected using a convenience sampling technique, and sampling was done by sending a structured online questionnaire via Google forms and printed questionnaires to participants who did not use the online Google forms. Results: Respondents that knew about self-medication were 97% of the 272 participants. Those that are aware of self-medication, have heard about it either through different avenues. Respondents who practiced self-medication before the COVID-19 pandemic were 239 (88%); those who practiced self-medication during the COVID-19 pandemic were 156 (57%); those that did not were 115 (43%). There was a statistically significant decrease in the number of respondents who practice self-medication during the COVID-19 pandemic lockdown compared to the practice before the pandemic lockdown. p < 0.05 at 95% confidence interval (OR = 5.39, 95% CI = 3.48, 8.32). Conclusion: Our investigation showed adequate knowledge of self-medication and a high level of self-medication practice with a decrease in self-medication practices during the COVID-19 pandemic lockdown compared to the practice before the lockdown.

University Lecturers and Students Could Help in Community Education About SARS-CoV-2 Infection in Uganda.

BACKGROUND: 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. AIM: The aim of this study was to determine the knowledge, attitudes, and preparedness/practices of lecturers and students in the fight against COVID-19. METHOD: 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. RESULTS: 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. CONCLUSION: The study identifies lecturers and students as potential stakeholders in the fight against community transmission of COVID-19.
