Decreasing hospitalizations through geriatric hotlines: a prospective French multicenter study of people aged 75 and above.

Background: The Emergency unit of the hospital (Department) (ED) is the fastest and most common way for most French general practitioners (GPs) to respond to the complexity of managing older adults patients with multiple chronic diseases. In 2013, French regional health authorities proposed to set up telephone hotlines to promote interactions between GP clinics and hospitals. The main objective of our study was to analyze whether the hotlines and solutions proposed by the responding geriatrician reduced the number of hospital admissions, and more specifically the number of emergency room admissions.

Impact of Geriatric Hotlines on Health Care Pathways and Health Status in Patients Aged 75 Years and Older: Protocol for a French Multicenter Observational Study.

Background: In France, emergency departments (EDs) are the fastest and most common means for general practitioners (GPs) to cope with the complex issues presented by elderly patients with multiple conditions. EDs are overburdened, and studies show that being treated in EDs can have a damaging effect on the health of elderly patients. Outpatient care or planned hospitalizations are possible solutions if appropriate geriatric medical advice is provided.

Early Sites of Virus Replication After Oral SIV Infection of Infant Macaques: Implications for Pathogenesis.

Despite optimization of preventative measures for vertical HIV-1 transmission, daily, roughly 400 infants become HIV infected, most of them through breastfeeding. Viral entry has been presumed to occur in the gastrointestinal tract; however, the exact entry site(s) have not been defined. Therefore, we quantified simian immunodeficiency virus (SIV) RNA and DNA in oral, intestinal, and systemic tissues of 15 infant macaques within 48-96 h after oral SIV exposure.

Validation of RPS13 as a reference gene for absolute quantification of SIV RNA in tissue of rhesus macaques.

Persistent HIV reservoirs and the absolute quantification of viral RNA copies in tissues have become a prominent focus of multiple areas ofHIV/SIV research. Absolute quantification of viral RNA via reverse transcription, quantitative PCR (RT-qPCR) necessitates the use of an appropriate RNA reference gene whose expression is unaffected by both experimental and confounding conditions. In this study, we demonstrate the utility of ribosomal protein S13 mRNA (RPS13) as a stable, medium abundance reference gene for RT-qPCR normalization of HIV/SIV RNA copy number.

Chlamydia trachomatis Infection of Endocervical Epithelial Cells Enhances Early HIV Transmission Events.

Chlamydia trachomatis causes a predominantly asymptomatic, but generally inflammatory, genital infection that is associated with an increased risk for HIV acquisition. Endocervical epithelial cells provide the major niche for this obligate intracellular bacterium in women, and the endocervix is also a tissue in which HIV transmission can occur. The mechanism by which CT infection enhances HIV susceptibility at this site, however, is not well understood.
