Mycobacterium tuberculosis remains one of the deadliest infectious agents globally. Amidst efforts to control TB, long treatment duration, drug toxicity, and resistance underscore the need for novel therapeutic strategies. Despite advances in understanding the interplay between microbiome and disease in humans, the specific role of the microbiome in predicting disease susceptibility and discriminating infection status in tuberculosis still needs to be fully investigated. We investigated the impact of M.tb infection and M.tb -specific IFNγ immune responses on airway microbiome diversity by performing TB GeneXpert and QuantiFERON-GOLD assays during the follow-up phase of a longitudinal HIV-Lung Microbiome cohort of individuals recruited from two large independent cohorts in rural Uganda. M.tb rather than IFNγ immune response mainly drove a significant reduction in airway microbiome diversity. A microbiome signature comprising Streptococcus, Neisseria, Fusobacterium, Prevotella, Schaalia, Actinomyces, Cutibacterium , Brevibacillus , Microbacterium , and Beijerinckiacea accurately discriminated active TB from Latent TB and M.tb- uninfected individuals., Competing Interests: All Authors declared no conflicts of interest., (© 2024 The Authors.)

Chronic Obstructive Pulmonary Disease (COPD) has significantly contributed to global mortality, with three million deaths reported annually. This impact is expected to increase over the next 40 years, with approximately 5 million people predicted to succumb to COPD-related deaths annually. Immune mechanisms driving disease progression have not been fully elucidated. Airway microbiota have been implicated. However, it is still unclear how changes in the airway microbiome drive persistent immune activation and consequent lung damage. Mechanisms mediating microbiome-immune crosstalk in the airways remain unclear. In this review, we examine how dysbiosis mediates airway inflammation in COPD. We give a detailed account of how airway commensal bacteria interact with the mucosal innate and adaptive immune system to regulate immune responses in healthy or diseased airways. Immune-phenotyping airway microbiota could advance COPD immunotherapeutics and identify key open questions that future research must address to further such translation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Kayongo, Robertson, Siddharthan, Ntayi, Ndawula, Sande, Bagaya, Kirenga, Mayanja-Kizza, Joloba and Forslund.)

Biorepositories are essential because they guarantee the proper storage and distribution of biospecimens and their associated data for current and future research. In Eastern and Central Africa, the Integrated Biorepository of H3Africa Uganda (IBRH3AU) at Makerere University in Uganda was the first of its kind. It is strategically located at Makerere University College of Health Sciences, which is home to some of Uganda's most relevant and impactful infectious and non-infectious disease research.  Since its inception as a pilot project in 2012, the IBRH3AU biorepository has grown into a state-of-the-art facility serving the H3Africa consortium and the rest of the scientific community. IBRH3AU has built a solid infrastructure over the past ten years with cutting-edge methods and technologies for the collection, processing, quality control, handling, management, storage and shipment of biospecimens. H3Africa researchers, local researchers, postgraduate and postdoctoral students, and the greater scientific community in Eastern and Central Africa and beyond have benefited from IBRH3AU's exceptional biobanking services., Competing Interests: No competing interests were disclosed., (Copyright: © 2022 Nsubuga G et al.)

Background: Comfort of patients with medical students is important and promotes appropriate clinical reasoning and skills development in the students. There is however limited data in this field in Uganda. In this study, we examined the attitudes and comfort of patients attending care at the medical and obstetrics/gynecology specialties in teaching hospitals of three public universities in Uganda., Methods: We conducted a cross sectional study among patients attending care at teaching hospitals for three public universities; Makerere University (Mak), Mbarara University of Science and Technology (MUST), and Gulu University (GU). Logistic regression was used to determine the magnitude of associations between independent and dependent variables. Two-sided p < 0.05 was considered statistically significant., Results: Eight hundred fifty-five patients participated in the study. Majority were aged 18 - 39 years (54%, n = 460), female (81%, n = 696) and married (67%, n = 567). Seventy percent (n = 599) of participants could recognize and differentiate medical students from qualified physicians, and had ever interacted with medical students (65%, n = 554) during earlier consultations. Regarding attitudes of patients towards presence of medical students during their consultations, most participants (96%; n = 818) considered involvement of medical students in patients' care as essential ingredient of training of future doctors. Most participants prefer that medical students are trained in the tertiary public hospitals (80%; n = 683) where they attend care. Participants who were single/never married were 68% less likely to recognize and differentiate medical students (aOR = 0.32, 95%CI: 0.22 - 0.53) from other members of the healthcare team as compared with married participants. Participants with university education had 55% lower odds of being comfortable with presence of medical students during consultation compared to those with primary education (aOR = 0.45, 95%CI: 0.21 - 0.94). Participants from MUST teaching hospital had twofold higher odds of being comfortable with presence of medical students compared to participants from Mak teaching hospitals (aOR = 2.01; 95%CI: 1.20 - 3.39)., Conclusion: Patients are generally comfortable with medical students' involvement in their care; they prefer to seek care in hospitals where medical students are trained so that the students may contribute to their care. Medical students need to introduce themselves appropriately so that all patients can know them as doctors in training; this will promote patients' autonomy and informed decisions., (© 2022.
