Do ART and Chemsex Drugs Get Along? Potential Drug-Drug Interactions in a Cohort of People Living with HIV Who Engaged in Chemsex: A Retrospective Observational Study.

Introduction: People living with HIV (PLWH) who engaged in chemsex are at risk of potential drug-drug interactions (pDDIs) with recreational drugs. This study aimed to characterize pDDIs between antiretroviral treatment (ART) and chemsex drugs and evaluate their association with unscheduled relevant hospital consultations.

Methods: We conducted a single-center, retrospective, observational study in a series of gay, bisexual, and other men who have sex with men (gbMSM) living with HIV who engaged in chemsex and who attended a tertiary hospital in Barcelona, Spain, from February 2018 through August 2019.

The signal of ill-defined CPT weakening entanglement in the system.

In the presence of quantum-gravity fluctuations (space-time foam), the CPT operator may be ill-defined. Its perturbative treatment leads to a modification of the Einstein-Podolsky-Rosen correlation of the neutral meson system by adding an entanglement-weakening term of the wrong exchange symmetry, the -effect. In the current paper we identify how to probe the complex in the entangled -system using the flavour ()-CP() eigenstate decay channels: the connection between the intensities for the two time-ordered decays (, ) and (, ) is lost.

Adoption of Preventive Measures and Attitudes Toward the H1N1 Influenza Pandemic in Schools.

Background: This study describes the perceived impact of H1N1 influenza and the adoption of the recommended measures to address the pandemic in schools.

Methods: A cross-sectional self-reported survey was conducted in 433 schools in Barcelona addressed to the school principal or the H1N1 influenza designated person. A descriptive analysis was performed, stratifying by educational level and type of school.

[Eating habits, sedentary behaviors and overweight and obesity among adolescents in Barcelona (Spain)].

Introduction: Breakfast is considered the most important meal of the day in an equilibrated diet. Skipping breakfast has been associated with overweight.
