Herpes zoster (HZ) is a common disease in older adults and immunocompromised patients, and is frequently associated with long-term complications that impact quality of life. Fortunately, more than one vaccine against HZ is now available in Mexico. Two expert consensus groups discussed adult vaccination strategies in Mexico, focusing on HZ in older adults and immunocompromised individuals; their insights are reported here.

Virtual Reality (VR) has proven to be a valuable tool for medical and nursing education. VR simulators are available at any time and from anywhere, and can be used with or without faculty supervision, which results in a significant optimization of time, space, and resources. In this paper we present a highly-configurable session designer for VR-based nursing education following the Standards for QUality Improvement Reporting Excellence: SQUIRE 2.

Human immune cells are under constant evolutionary pressure, primarily through their role as first line of defence against pathogens. Most studies on immune adaptation are, however, based on protein-coding genes without considering their cellular context. Here, using data from the Human Cell Atlas, we infer the gene adaptation rate of the human immune landscape at cellular resolution.

Article Synopsis
  • Fanconi anemia (FA) is a rare genetic disorder marked by varying symptoms and significant chromosome fragility, leading to severe health issues like cancer and bone marrow failure.
  • The Spanish Registry of Patients with FA gathered data from 227 patients over 30 years, revealing an 86% cumulative cancer incidence by age 50, with outcomes differing based on chromosome fragility and specific gene mutations.
  • Findings suggest that patients with mutations allowing some protein function (genetic hypomorphism) tend to have better health outcomes, indicating potential for new therapies that could enhance mutant FA protein function to improve patient prognosis.

  • - Viremic non-progressors (VNPs) are a rare group of HIV-1 individuals who maintain normal CD4 T cell counts despite high viral loads, resembling natural hosts of simian immunodeficiency virus, but the reasons for this are not fully understood.
  • - A study using single-cell and multiomics methods examined 16 VNPs and 29 HIV+ progressors, revealing genetic factors like CCR5Δ32 heterozygosity and lower CCR5 expression, alongside reduced intestinal disruption and immune responses in VNPs.
  • - The research highlights various traits contributing to the immune stability in VNPs, indicating important insights for potential HIV treatment strategies in the future.

Background: Despite a shortage of potential donors for heart transplant in the United States, most potential donor hearts are discarded. We evaluated predictors of donor heart acceptance in the United States and applied machine learning methods to improve prediction.

Methods: We included a nationwide (2005-2020) cohort of potential heart donors in the United States (n=73 948) from the Scientific Registry of Transplant Recipients and a more recent (2015-2020) rigorously phenotyped cohort of potential donors from DHS (Donor Heart Study; n=4130).

Article Synopsis
  • This study involved three experiments using rats to investigate how a retrieval-extinction procedure influences their learning about alcohol seeking in different contexts (ABA and AAB renewal).
  • Rats were trained to run for beer in one environment, then underwent extinction training in another environment, with some receiving beer beforehand and others not.
  • The findings indicate that when rats did not receive beer exposure before extinction, they showed a renewal effect in seeking alcohol, but this effect was blocked when they had beer exposure prior to extinction.

Article Synopsis
  • The study analyzes the risk of intracranial bleeding in patients undergoing anticoagulation for venous thromboembolism (VTE), emphasizing the risk persists beyond initial treatment.
  • Researchers developed two phase-specific prognostic scores based on data from over 77,000 VTE patients, utilizing multivariable Cox regression to identify relevant risk factors.
  • The new scores showed a c-statistic of 0.68, indicating they are more effective than existing models in predicting bleeding risks, potentially improving anticoagulation management and reducing mortality from bleeding.

Coronavirus disease 2019 (COVID-19) has affected not only individual lives but also the world and global systems, both natural and human-made. Besides millions of deaths and environmental challenges, the rapid spread of the infection and its very high socioeconomic impact have affected healthcare, economic status and wealth, and mental health across the globe. To better appreciate the pandemic's influence, multidisciplinary and interdisciplinary approaches are needed.

The aim of our cross-sectional and longitudinal study is to assess the relationship between daytime and night-time sleep duration and health-related quality of life (HRQoL) in adults with metabolic syndrome after a 1-year healthy lifestyle intervention. Analysis of the data from 2119 Spanish adults aged 55-75 years from the PREDIMED-Plus study was performed. Sleep duration was assessed using a wrist-worn accelerometer.

The use of 50+ year-old donors for heart transplant (HT) is rare in the United States. We assessed reasons for this-and whether it reflects concern about age itself or associated risk factors-using a survey of US HT centers. The Donor Heart Study enrolled US adult potential heart donors from 2015 to 2020.

, the causative agent of Chagas disease (), is a highly complex zoonosis that is present throughout South America, Central America, and Mexico. The transmission of this disease is influenced by various factors, including human activities like deforestation and land use changes, which may have altered the natural transmission cycles and their connection to the environment. In this study conducted in the Argentine Chaco region, we examined the transmission dynamics of by collecting blood samples from wild and domestic animals, as well as triatomine bugs from human dwellings, across five sites of varying anthropic intervention.

Gonadotropin releasing hormone (GnRH) synthesis and secretion regulates seasonal fertility. In the brain, the distribution of GnRH-positive neurons is diffuse, hindering efforts to monitor variations in its cellular and tissue levels. Here, we aim at assessing GnRH immunoreactivity in nuclei responsible for seasonal fertility regulation (SFR) within the posterior, anterior, and preoptic areas of the basal hypothalamus during estrous in ewes.

Sourdough bread enriched with soluble fiber (by in-situ exopolysaccharides production) and insoluble fiber (by gazpacho by-products addition) showed prebiotic effects an in vitro dynamic colonic fermentation performance with obese volunteer's microbiota. Bifidobacterium population was maintained whereas Lactobacillus increased throughout the colonic sections. Conversely, Enterobacteriaceae and Clostridium groups clearly decreased.

Article Synopsis
  • This study aimed to evaluate the effectiveness and safety of two procedures—peroral endoscopic myotomy with septotomy (POEM+S) and without septotomy (POEM-S)—in treating symptomatic epiphrenic diverticula (ED) alongside motility disorders.
  • Conducted across 21 international centers from 2014 to 2023, the study included 85 patients, measuring clinical success primarily through the Eckardt score.
  • Results indicated that both procedures had similar clinical success rates (83% for POEM+S vs. 86.8% for POEM-S), technical success, and adverse event rates, but POEM-S patients had a longer hospital stay.

Background: Viral infections are known to impact the pancreato-biliary system; however, there are limited data showing that the same is true of COVID-19. Endoscopic retrograde cholangiopancreatography (ERCP) can safely be performed in patients with COVID-19 infection, but outcomes of patients with COVID-19 infections and concomitant pancreatic and biliary disease requiring endoscopic intervention are unknown.

Aims: This study aims to evaluate the severity of pancreaticobiliary diseases and post-ERCP outcomes in COVID-19 patients.

Presently, there has been a noticeable rise in the consumption of poultry meat within the general population, particularly focusing on poultry sourced from alternative rearing systems as opposed to intensive ones. This study evaluated the impact of incorporating house cricket (Acheta domesticus,AD) larvae meal into the diet of 2 slow-growing chicken strains on their carcass traits and meat quality. A total of 256 one-day-old male chicks were utilized, with 128 belonging to the Red (R) strain and 128 to the Naked Neck (NN) strain.
