Transplantation of a genetically modified porcine heart into a live human.

Following our previous experience with cardiac xenotransplantation of a genetically modified porcine heart into a live human, we sought to achieve improved results by selecting a healthier recipient and through more sensitive donor screening for potential zoonotic pathogens. Here we transplanted a 10-gene-edited pig heart into a 58-year-old man with progressive, debilitating inotrope-dependent heart failure due to ischemic cardiomyopathy who was not a candidate for standard advanced heart failure therapies. He was maintained on a costimulation (anti-CD40L, Tegoprubart) blockade-based immunomodulatory regimen.

[Oral health conditions and nutritional, functional and cognitive status - An approach to the institutionalized older adult].

Introduction/objective: Multidimensional geriatric assessment is an important diagnostic method in geriatrics. The objective of this article was to establish the relationship between nutritional, functional, cognitive status and oral health of institutionalized older adults.

Methodology: A cross-sectional observational study was carried out, where 93 institutionalized older adults participated, including oral assessment and Barthel, Minimental, Mininutritional and Yesavage scales.

Nonadiabatic Excited-State Molecular Dynamics with an Explicit Solvent: NEXMD-SANDER Implementation.

In this article, the nonadiabatic excited-state Molecular dynamics (NEXMD) package is linked with the SANDER package, provided by AMBERTOOLS. The combination of these software packages enables the simulation of photoinduced dynamics of large multichromophoric conjugated molecules involving several coupled electronic excited states embedded in an explicit solvent by using the quantum/mechanics/molecular mechanics (QM/MM) methodology. The fewest switches surface hopping algorithm, as implemented in NEXMD, is used to account for quantum transitions among the adiabatic excited-state simulations of the photoexcitation and subsequent nonadiabatic electronic transitions, and vibrational energy relaxation of a substituted polyphenylenevinylene oligomer (PPV3-NO2) in vacuum and methanol as an explicit solvent has been used as a test case.

Antimicrobial stewardship programs in a Mexican private healthcare system: a self-assessment of core elements.

Background: Antimicrobial stewardship programs (ASPs) refer to a set of coordinated actions that improve the quality of care and combat antimicrobial resistance. Currently, information regarding the status of ASPs in Mexico is scarce. We aimed to describe the status of ASPs in 12 hospitals from Christus Muguerza Healthcare System.
