Purpose Of Review: The management of thoracic empyema is often complicated by diagnostic delays, recurrence, treatment failures and infections with antibiotic resistant bacteria. The emergence of artificial intelligence (AI) in healthcare, particularly in clinical decision support, imaging, and diagnostic microbiology raises great expectations in addressing these challenges.

Recent Findings: Machine learning (ML) and AI models have been applied to CT scans and chest X-rays to identify and classify pleural effusions and empyema with greater accuracy.

Article Synopsis
  • MERS-CoV is a virus found in dromedary camels on the Arabian Peninsula, which can occasionally infect humans, but its diversity has been under-studied, especially during the COVID-19 pandemic.
  • A study conducted from November 2023 to January 2024 collected 558 camel swab samples in Saudi Arabia, revealing that 39% tested positive for MERS-CoV RNA, with sequencing of 42 MERS-CoVs and other related coronaviruses.
  • The genetic analysis showed that MERS-CoV sequences were closely related to the B5 lineage and had unique characteristics, highlighting the need for further study to assess their public health implications and potential for human transmission.

Lassa fever (LF) virus (LASV) is endemic in Sierra Leone (SL) and poses a significant public health threat to the region; however, no risk factors for clinical LF have been reported in SL. The objective of this study was to identify the risk factors for clinical LF in an endemic community in SL. We conducted a case-control study by enrolling 37 laboratory-confirmed LF cases identified through the national LF surveillance system in SL and 140 controls resided within a one-kilometre radius of the case household.

Purpose: Urinary sepsis is the leading cause of mortality in the setting of endourological procedures for stone treatment such as URS and PCNL; renal stones themselves may be a source of infection. Aim of this study is to determine the diagnostic accuracy of stone cultures (SC) collected during URS and PCNL in predicting post-operative septic complications, compared to preoperative bladder urine culture (BUC).

Methods: We performed a systematic review (SR) of literature according to the PRISMA guidelines; Literature quality was evaluated according to The Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I) assessment tool.

On August 14, 2024, following a regional declaration by the Africa Centres for Disease Control and Prevention, the World Health Organization declared mpox a Public Health Emergency of International Concern, marking the second such declaration in two years. A series of outbreaks involving the more virulent clade I virus (compared to clade II, which caused a global outbreak in 2022), has now spread in 13 African countries, exposing the inadequacies of the public health infrastructure in these settings. There was significant investment during the 2022 global outbreak, but these efforts failed to address vaccine access and treatment in the Global South.

Millions of pilgrims travel annually to Makkah and Madinah, Saudi Arabia, for the Hajj, posing unique challenges for public health management and disease control. The large influx of pilgrims from diverse backgrounds traveling to a confined geographic area, coupled with the close proximity and interactions among them, create significant pressure on the healthcare system and heighten the potential for the spread of communicable diseases. This review examines current trends in communicable diseases and their impact, drawing insights from expert perspectives on the required (i.

Background: Human immunodeficiency virus (HIV) and tuberculosis (TB) are major contributors to morbidity and mortality in sub-Saharan Africa including Cameroon. Pharmacogenetic variants could serve as predictors of drug-induced hepatotoxicity (DIH), in patients with TB co-infected with HIV. We evaluated the occurrence of DIH and pharmacogenetic variants in Cameroonian patients.
