Africa, the world’s second-largest continent is home to 1.5 billion people, accounting for nearly 20% of the global population, (60% under age 25). By 2050, Africa’s population will be 2.5 billion, and by 2035, more young Africans will be entering the workforce each year than in the rest of the world combined. Africa also hosts a rich social, cultural, and geopolitical diversity across its 5 geopolitical zones covering 54 countries. It is the most genetically, culturally, and linguistically diverse region on the planet. However, Africa’s contribution to the global economy could be more significant if it urgently embraces the brain …

Potential Effect Of Statins As Adjuvant Anti‑Tuberculosis Agents: A Short Communication, Mehwish Hanif, Ayesha Tariq, Laiba Zahoor

Digital Journal of Clinical Medicine

Tuberculosis is a chronic pulmonary infectious disease caused by Mycobacterium tuberculosis and can affect other parts of the body such as bones, brain, and lymph nodes (extra pulmonary Tb). Statins, primarily used for hyperlipidemia, have demonstrated anti-inflammatory and immunomodulatory properties that may help prevent and manage TB. They inhibit HMG-CoA reductase, reduce cholesterol synthesis and interfere with phagocytosis crucial for TB infection. Given the rise in resistance to first-line anti-tubercular therapies, Statins have shown promise as adjunctive agents by potentially shortening treatment duration, reducing adverse effects, and improving outcomes, particularly in immunocompromised and diabetic patients. Based on these findings, Statins …

Resveratrol And Il-6 Modulation Of Cxcl1 Expression And Viability In Human Breast Cancer Cell Lines, Entkhab M. A. Alanisi, Aida H. Alobaidi, Khalid Alyodawi

AUIQ Complementary Biological System

This study aims to investigate, through in vitro methods, the molecular, immunofluorescent, and immunohistochemical effects of resveratrol and IL-6 on CXCL1 gene/protein expression in human breast cancer cells (MCF-7). MCF-7 and MCF-10A cell lines were cultured and divided into four groups: control, IL-6-treated, resveratrol-treated, and a combination-treated group. CXCL1 gene expression was assessed by real-time PCR (RT-PCR), while CXCL1 protein levels were analyzed using immunofluorescence and immunohistochemistry. Cell viability was quantified by MTS assay using ELISA. CXCL1 gene/protein was overexpressed in MCF-7 cells, especially in the IL-6-treated group, but reduced in both resveratrol and combination-treated groups. MTS assay showed increased …

The Thai Journal of Veterinary Medicine

nfluenza A viruses (IAVs) can infect birds and various mammals. In this study, we retrospectively isolated and characterized IAVs (n=8) from oropharyngeal and cloacal swab samples of free-grazing ducks collected during December 2018 to December 2021, by using egg inoculation and whole-genome sequencing. The IAVs could be subtyped as IAV-H4N2 (n = 3) and IAV-H4N8 (n = 5) using real-time RT-PCR assays. Genetic and phylogenetic analyses revealed that all eight genes of Thai IAV-H4 belong to the Avian Eurasian lineage. Both Thai IAV-H4N2 and IAV-H4N8 exhibited low pathogenic avian influenza (LPAI) characteristics and were susceptible to oseltamivir and amantadine. This …

Thermal Compensation Algorithm In Manoscan™ High-Resolution Esophageal Manometry: Does It Really Affect Manometry Metrics And Final Diagnosis?, Ekrem Aslan, Erdem Akbal

Turkish Journal of Medical Sciences

Background/aim: The accuracy of pressure measurements with ManoScan™ high-resolution manometry (HRM) catheters decreases due to the development of pressure drift (PD) resulting from variations between room and body temperature. The corrective algorithm called thermal compensation (TC), added to the manometry software program by the manufacturer is used to prevent the development of PD. To date, no studies have demonstrated that PD leads to changes in manometry metrics and/or clinical diagnosis. The present study aims to demonstrate the impact of the TC algorithm on HRM metrics and final diagnosis.

Materials and methods: Records of 124 consecutive esophageal HRM studies with ManoScan™ …

Turkish Journal of Medical Sciences

Background/aim: This study aimed to report the 5-year outcomes of patients with newly diagnosed branch retinal vein occlusion (BRVO).

Materials and methods: A retrospective review of patient charts was conducted. Data on central macular thickness (CMT), best-corrected visual acuity (BCVA), photoreceptor integrity, number of intravitreal (IV) antivascular endothelial growth factor (anti- VEGF) injections administered, and treatment regimen were assessed.

Results: Ninety-seven eyes from individual patients with a mean age of 70.90 ± 11.49 (38–92) were included. The mean BCVA improved, and the mean CMT decreased at all follow-up visits following treatment (p < 0.05). Thirty-two eyes (33%) gained 3 lines of BCVA at the five-year follow-up. The mean number of total IV anti-VEGF injections administered was 19 ± 13.35 (1–49) during the five-year period, and 27.83% of patients received rescue laser treatment. Fifty-four percent of eyes received three consecutive monthly loading doses of IV anti-VEGF injections. The mean change in BCVA in the loading dose (+) group was significantly greater than in the loading dose (–) group at 1-year and subsequent visits. The loading dose (+) group showed a significantly greater reduction in CMT compared to the loading dose (–) group. The mean estimated time for BCVA to decline by ≥3 lines was 117 ± 8.74 months (95% CI = 100.21–134.51)

Conclusion: Anti-VEGF treatment was effective in improving anatomical …

Turkish Journal of Medical Sciences

Background/aim: To evaluate the short-term efficacy and safety of nondamaging retinal laser therapy (NRT) for retinitis pigmentosa-associated cystoid macular edema (RP-CME) and analyze anatomical and functional outcomes.

Materials and methods: A retrospective case series of 40 eyes from 30 patients with RP-CME was conducted. The patients underwent NRT using a PASCAL laser system with endpoint management (EpM) software. Central macular thickness (CMT) and best-corrected visual acuity (BCVA) were assessed at baseline and 2 months posttreatment. Long-term follow-up data, including recurrence rates were also reviewed.

Results: At the 2-month follow-up, NRT significantly reduced mean CMT by 79.7 μm (p < 0.001) and improved BCVA by 0.10 LogMAR (p < 0.001). Complete resolution of CME was observed in 30% of the eyes, while 52.5% experienced recurrence within 6 months. Unilateral cases exhibited greater CMT reductions than bilateral cases (p < 0.05). No retinal damage from the laser was observed. The long-term sustainability of these effects remains unclear, and repeated treatments have not yet been assessed.

Conclusion: NRT …
