A Rapid Polymerase Chain Reaction Assay (Ampli-cor(R)-PCR) was evaluated for the detection of Chlamydia trachomatis in specimens from 179 high risk patients. The results were compared to McCoy cell culture and specimens were retested with Amplicor(R) and primers for the Major Outer Membrane Protein (MOMP) gene when discrepancy occurred. Of 88 females enrolled in the study, 30 were infected (34%). Sensitivity, selectivity, predictive value of a positive (PVP) and a negative (PVN) on endocervical specimens were 97%, 96.5%, 96.5% and 98% respectively. Of 91 male urine specimens, 33 (36%) came from infected patients. The sensitivity and specificity of the Amplicor(R) assay was 94% and 74% respectively for male urine specimens and the PVP and PVN were 72% and 96% respectively. The sensitivity was low on the original run on urethral specimens but the majority of false negative specimens became positive when retested. Amplicor(R) performed on urine samples was the most sensitive test for detecting Chlamydial infections in males.

Rapid and accurate detection of Chlamydia psittaci, the causative agent of psittacosis, is crucial for both human and animal health but presents significant challenges, particularly in grassroots health institutions. Our previous PDTCTR fluorescence sensing platform, which combined the engineered Cas12f1_ge4.1 system with recombinase polymerase amplification (RPA), significantly enhanced detection efficiency.

The prevalence of hepatitis B virus infection remains high in the Democratic Republic of Congo (DRC), constituting a public health problem in view of the fatal complications it causes, notably cirrhosis and hepatocellular carcinoma. The aim of this study was to provide an overview of the situation of viral hepatitis B in the DRC and in particular its implications for public health. A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) group guidelines.

: Serotonin and the serotonin transporter (SERT) may have a multifaceted, but not fully understood, role in obstructive sleep apnea (OSA) and its impact on mental health in this group of patients. This study aimed to investigate changes in serotonin and the serotonin transporter (SERT) and their association with depressive and insomnia symptoms. : This study included 76 participants (OSA group: = 36, control group (CG): = 40) who underwent polysomnography, while venous blood samples (evening and morning) were analyzed for serotonin and the SERT using ELISA.

In immunocompromised patients, pneumonia presents a diagnostic challenge due to diverse etiologies, nonspecific symptoms, overlapping radiological presentation, frequent co-infections, and the potential for rapid progression to severe disease. Thus, timely and accurate diagnosis of all pathogens is crucial. This narrative review explores the latest advancements in microbiological diagnostic techniques for pneumonia in immunocompromised patients.
