Endoscopic gastric plication is an emerging procedure for obesity management, facilitated by advances in intraluminal suturing technology. However, concerns persist regarding the complete transfixion of sutures and their long-term durability. We present the case of a 28-year-old patient with a BMI of 31 kg/m² who underwent laparoscopic gastric plication using nonabsorbable sutures to ensure complete transfixion under direct visualization.

Emotion enhances the subjective experience of recollection. Previous research examined associations between memory accuracy and metamemory confidence judgments, but these studies have not quantified the relationship between accuracy and metacognitive confidence judgments. In this study we utilize signal detection theory frameworks to investigate how memory accuracy (measured by discrimination sensitivity) and the alignment between metamemory confidence judgments and memory accuracy (ie.

Article Synopsis
  • The European badger is a common species that can carry various diseases, including Leishmania, with inconsistent findings reported in different studies, especially in Spain.
  • This study analyzed nine European badgers from northeastern Spain to investigate Leishmania infection, revealing lesions in the lymph nodes and spleens of six badgers and confirming the presence of Leishmania-like structures in one.
  • The results indicate a 11.11% infection rate among the badgers examined, suggesting the need for more research on wildlife reservoirs of this zoonotic disease.

Article Synopsis
  • The study aimed to investigate whether older patients (≥65 years) have a diminished tachypneic response to hypoxia, meaning they may not breathe faster in response to low oxygen levels as much as younger patients do.
  • Researchers analyzed data from 7126 patients in Spanish emergency departments, measuring peripheral arterial oxygen saturation (SatO2) and respiratory rate (RR) upon arrival, finding significant correlations across all age groups studied.
  • Results indicated that as patient age increased, the respiratory rate response to decreasing oxygen levels slowed down, with younger individuals showing a faster increase in breathing rate in response to hypoxia compared to older individuals, particularly those aged ≥90 years.

The improvement in survival rates in pediatric malignancies has led to an increase in the number of cancer survivors who are at risk of developing cardiotoxicity and heart failure. Cardiac dysfunction in these patients can occur asymptomatically, and the diagnosis in a symptomatic phase is associated with reduced treatment response and worse prognosis. For this reason, it is essential to establish protocols to follow up on these patients and identify those at risk of cardiotoxicity in order to start early and effective therapies.

Carbohydrates comprise the largest fraction of most diets and exert a profound impact on health. Components such as simple sugars and starch supply energy, while indigestible components, deemed dietary fiber, reach the colon to provide food for the tens of trillions of microbes that make up the gut microbiota. The interactions between dietary carbohydrates, our gastrointestinal tracts, the gut microbiome and host health are dictated by their structures.

The feline population is extensive in urban areas worldwide, comprising stray and domestic cats. Cats, acting as reservoirs, can transmit various zoonotic organisms to humans, which can cause significant public health issues. We evaluated the seroprevalence of zoonotic pathogens in stray cats in an urban area of northeast Spain (the city of Zaragoza) to assess potential risks to human health.

Article Synopsis
  • The study investigates how the specific composition of monosaccharides in dietary fibers affects fermentation by gut bacteria in cats, utilizing advanced techniques for analyzing complex carbohydrates.
  • Results indicate that the presence of glucose and xylose significantly influences pH levels during fermentation, correlating with the production of certain short-chain fatty acids (SCFAs) like lactic and propionic acid.
  • The findings suggest that monosaccharide composition is a key factor that can help compare different dietary fibers and understand their impact on gut microbiota diversity and metabolism.

Objective: Analyse the association between the use of diagnostic tests and the characteristics of older patients 65 years of age or more who consult the emergency department (ED).

Methods: We performed an analysis of the EDEN cohort that includes patients who consulted 52 Spanish EDs. The association of age, sex, and ageing characteristics with the use of diagnostic tests (blood tests, electrocardiogram (ECG), microbiological cultures, X-ray, computed tomography, ultrasound, invasive techniques) was studied.

Article Synopsis
  • A study evaluated the impact of older adults (aged 75+) spending a night in emergency departments (ED) on their risk of in-hospital mortality, comparing those who were admitted to wards before midnight versus those who stayed in the ED until morning.
  • Despite slightly higher in-hospital mortality rates for those in the ED (10.7%) compared to the ward group (9.5%), the differences were not statistically significant, indicating that staying overnight in the ED did not conclusively increase mortality risk.
  • The findings suggest that while older patients may face potential risks when waiting in an ED overnight, especially in non-academic hospitals, overall, there was no evidence of longer hospital stays or higher mortality rates tied to this practice

Microbiota-directed complementary food (MDCF) formulations have been designed to repair the gut communities of malnourished children. A randomized controlled trial demonstrated that one formulation, MDCF-2, improved weight gain in malnourished Bangladeshi children compared to a more calorically dense standard nutritional intervention. Metagenome-assembled genomes from study participants revealed a correlation between ponderal growth and expression of MDCF-2 glycan utilization pathways by Prevotella copri strains.

Purpose Of Review: This review aims to compare evidence on four criteria (embryo implantation, obstetric outcomes, patient convenience, and IVF-unit efficiency) by analyzing published research on different endometrial preparation methods for frozen embryo transfer (FET).

Recent Findings: While the artificial-FET cycle provides advantages in scheduling and implantation, it falls short in ensuring optimal obstetric outcomes. In contrast, natural-FET ensures embryo implantation conditions if ovulation is correctly identified.
