Following the two-year mark of the COVID-19 pandemic's onset, the Mexican Institute for Social Security (IMSS) reconceived future initiatives tailored to the evolving requirements of the populace and social security entities. The Institute, as a key element in fostering Mexican well-being, pursued an IMSS that is preventive, resilient, comprehensive, innovative, sustainable, modern, and accessible, guided by the National Development Plan and the Strategic Health for Wellbeing Program. Microbiological active zones In light of this, the Medical Services Director initiated the PRIISMA Project, a three-year strategy that sought to innovate and refine medical care procedures, beginning with the recovery of medical services and pinpointing beneficiary groups in the most precarious situations. The PRIISMA project encompassed five key sub-projects, including: 1. Addressing the needs of vulnerable individuals; 2. Providing high quality, efficient healthcare; 3. IMSS Plus preventive measures; 4. The programs at the IMSS University; and 5. The restoration of medical facilities and services. The medical care strategies implemented across each project aim to improve access for all IMSS beneficiaries and users, considering human rights and prioritizing specific groups; the objective being to bridge gaps in healthcare access, leaving no one behind, and exceeding pre-pandemic service levels. This document summarizes the strategies and progress made by PRIISMA sub-projects in 2022.

The relationship between neurological damage and senility in individuals aged 100 and older, as well as those in their 90s, continues to be an enigma.
We analyzed brain tissue sourced from 100 centenarians and 297 nonagenarians in The 90+ Study, a community-based, longitudinal study of aging. Between centenarians and nonagenarians, we analyzed the prevalence of 10 distinct neuropathological modifications and their correlation with dementia and cognitive function.
The neuropathological examination revealed that 59% of centenarians and 47% of nonagenarians showed at least four instances of such changes. Neuropathological alterations in centenarians correlated with a heightened likelihood of dementia, with these odds remaining substantial when juxtaposed against those of nonagenarians. Each additional neuropathological finding was accompanied by a two-point drop in the Mini-Mental State Examination scores in each of the two groups.
Neuropathological modifications in the brains of centenarians are a robust indicator of dementia, thus underscoring the vital significance of strategies to decelerate or forestall the accumulation of multiple such changes in the aging brain to promote cognitive well-being.
Among the elderly who reach the age of one hundred, individual and multiple neuropathological changes are widespread. These neuropathological changes are firmly connected to dementia. This connection endures without any lessening of its force with increasing age.
It is common to find a variety of neuropathological changes, including both individual and multiple, in centenarians. Dementia is strongly correlated with these neuropathological changes. This association's impact does not weaken with the passage of time.

Challenges in current high-entropy alloy (HEA) thin-film coating synthesis encompass facile preparation, precise thickness control, seamless integration, and economical production. HEA thin films based on noble metals face particular challenges with conventional sputtering, due to limitations in thickness control and the high cost of high-purity noble metal targets. A novel synthesis method for quinary HEA coatings, comprising noble metals (Rh, Ru, Pt, Pd, and Ir), is described herein for the first time. This method leverages sequential atomic layer deposition (ALD) with subsequent electrical Joule heating for alloying. A 50 nm thick quinary HEA thin film, characterized by an atomic ratio of 2015211827, exhibits promise as a catalyst support, showcasing improved electrocatalytic hydrogen evolution reaction (HER) performance, marked by lower overpotentials (e.g., from 85 mV to 58 mV in 0.5 M H2SO4) and enhanced stability (retaining over 92% of the initial current after 20 hours at a 10 mA/cm2 current density in 0.5 M H2SO4), significantly outperforming other noble metal-based structures within this study. HEA's effective electron transfer, coupled with an abundance of active sites, is responsible for the improved material characteristics and device performance. Not only does this work present RhRuPtPdIr HEA thin films as promising materials for the HER, but it also illuminates the method of achieving controllable fabrication of conformal HEA-coated complex structures across a diverse range of applications.

For photoelectrocatalytic water splitting to function, charge transfer at the semiconductor/solution interface is essential. Phenomenological insights into charge transfer in electrocatalytic processes are available through the Butler-Volmer theory; however, the photoelectrocatalytic counterpart struggles to fully comprehend interfacial charge transfer, as light, bias, and catalysis interact in complex ways. Trastuzumab Surface potential measurements, performed operando, distinguish between charge transfer and surface reaction processes. We show that the surface reaction boosts photovoltage via a photoinduced charge transfer mechanism related to the reaction, as seen in a SrTiO3 photoanode. We demonstrate that the charge transfer associated with the reaction modifies the surface potential, exhibiting a linear relationship with the interfacial charge transfer rate of water oxidation. A general rule for the interfacial transfer of photogenerated minority carriers is demonstrated by the linear behavior's invariance to variations in applied bias and light intensity. We predict the linear rule will be a phenomenological model for elucidating the nature of interfacial charge transfer in photoelectrocatalytic systems.

Single-chamber pacing may be a viable option for elderly patients undergoing assessment. The physiological mode of operation in sinus rhythm patients is better served by a VDD pacemaker (PM), preserving atrial sensing, than by VVI devices. The long-term impact of VDD pacemakers on elderly patients with atrioventricular block is the subject of this research.
A retrospective and observational study of 200 elderly patients, of whom 75 years of age, exhibiting AV block and normal sinus rhythm, and consecutively implanted with VDD pacemakers between 2016 and 2018, was undertaken. The subsequent 3-year follow-up period allowed for the assessment of pacemaker implantation complications and the evaluation of baseline clinical features.
The average age, calculated as a mean, was eighty-four years and five months. In a three-year follow-up study, an impressive 905% (n=181) of patients demonstrated preservation of their initial VDD mode. From the total patient population, 19 (95%) shifted to VVIR mode; 11 (55%) of these patients switched due to P-wave undersensing, and 8 (4%) due to the persisting atrial fibrillation condition. A lower amplitude of the sensed P wave was observed in the patients at baseline, with a median value of 130 (interquartile range 99-20) contrasting with 97 (interquartile range 38-168), indicating a statistically significant difference (p=0.004). During the follow-up period (FUP), a mortality rate of one-third of the patients was observed, with 89% (n=58) of these deaths attributable to non-cardiovascular causes. Ultrasound bio-effects The absence of a significant association was observed between atrial sensing loss during the follow-up (FUP) and mortality from all causes, cardiovascular causes, and non-cardiovascular causes (p=0.58, p=0.38, and p=0.80, respectively). However, a decline in atrial sensing capabilities during the follow-up phase was observed in conjunction with the appearance of new atrial fibrillation (127% vs. .). A statistically powerful correlation was found, indicated by a 316% increase and a p-value of 0.0038.
Long-term VDD pacing proves to be a trustworthy pacing option for the elderly. A considerable portion of VDD-paced elderly patients adhered to their pre-existing VDD mode programs, demonstrating consistent atrial sensing.
In elderly individuals, VDD pacing remains a trustworthy pacing choice, even over extended periods. Most elderly patients treated with VDD pacing continued with their initial VDD mode program, ensuring good atrial sensing function.

The IMSS, since 2015, has designed and implemented the Infarct Code emergency protocol for acute myocardial infarction care, with the ultimate intention of enhancing diagnostic accuracy and treatment efficacy, thus lowering the mortality rate. The nationwide implementation of the IMSS Bienestar healthcare model, in several states, facilitates the potential to extend the network of protocol services, benefiting not solely the entitled population but also those without social security, especially those who reside in socially deprived communities, to fulfill Article 40 of the Constitution. Based on resources available within the IMSS Ordinario and Bienestar systems, this document outlines the proposal to extend and intensify the Infarct Code care service network.

In Mexican healthcare, the Mexican Social Security Institute, Mexico's most prominent social security entity, holds a vital position. Across nearly eight decades, the entity has grappled with significant obstacles, experiences that have profoundly shaped the nation's health policy strategies. The epidemiological transition, characterized by high rates of chronic-degenerative diseases, was dramatically highlighted by the COVID-19 health emergency. This translated into a considerable rise in the risk of complications and mortality when confronted with emerging pathogens. Health care systems and policies at the institute are being redesigned to deliver pioneering solutions and fulfil the nation's pledge of social security.
