Background: Evaluate the misuse of proton pump inhibitors (PPIs) in geriatric long-term care (LTC) patients and improve caregiving by de-prescribing non-relevant PPIs in this population.

Aim: This study was conducted in the long-term care department of the geriatric hospital Pierre-Garraud in Lyon. All patients receiving PPI for more than 8 weeks were included.

Article Synopsis
  • Multiple assays are used for diagnosing neurosyphilis (NS) from cerebrospinal fluid (CSF), but there's no definitive 'gold standard' test.
  • This study assessed two PCR tests and three serological techniques on CSF samples from 143 patients suspected of NS.
  • While molecular tests showed high specificity, none had great sensitivity; serological tests like treponemal tests excelled in sensitivity but were less specific, indicating the need for a combined approach of clinical assessment and lab tests for accurate NS diagnosis.

Objectives: We evaluated a real-time quantitative PCR (qPCR) for detection of the (TP) genome in clinical samples through simultaneous detection of two genomic targets.

Methods: We performed qPCR with TaqMan technology using two TP genes, and , as targets, with an internal positive control. The qPCR assay was compared with syphilis diagnosis based on a combination of clinical examination, serological results and inhouse nested PCR (nPCR).

Gram-positive Streptococcus pyogenes (group A Streptococcus or GAS) is a major skin pathogen and interacts with keratinocytes in cutaneous tissues. GAS can cause diverse suppurative and inflammatory infections, such as cellulitis, a common acute bacterial dermo-hypodermitis with a high morbidity. Bacterial isolation yields from the lesions are low despite the strong local inflammation observed, raising numerous questions about the pathogenesis of the infection.

Epidemiological and genome-wide association studies of severe psychiatric disorders such as schizophrenia (SZ) and bipolar disorder (BD), suggest complex interactions between multiple genetic elements and environmental factors. The involvement of genetic elements such as Human Endogenous Retroviruses type 'W' family (HERV-W) has consistently been associated with SZ. HERV-W envelope gene (env) is activated by environmental factors and encodes a protein displaying inflammation and neurotoxicity.
