Background: Recent studies indicate the need to examine how the gut microbiota-brain axis is implicated in pain, sensory reactivity and gastro-intestinal symptoms in autism spectrum disorder (ASD), but no scale exists that assesses all these constructs simultaneously.

Methods: We created a pool of 100 items based on the real-world experience of autistic people, and a multidisciplinary team and stakeholders reduced this pool to 50 items assessing pain, sensory hypersensitivity, and sensory hyposensitivity. In the present study, we present this new assessment tool, the Pain and Sensitivity Reactivity Scale (PSRS), and examine its psychometric properties in a sample of 270 individuals with autism spectrum disorder (ASD; mean age = 9.

Background And Objectives: Hyponatraemia is common in elderly and hospitalised patients, often caused by the syndrome of inappropriate antidiuretic hormone secretion (SIADH). This study evaluates the efficacy and safety of tolvaptan and urea in patients with hyponatraemia and SIADH.

Materials And Methods: An observational cohort study was conducted on 198 patients with SIADH and hyponatraemia (Na+ <135 mmol/L) at the Complejo Hospitalario Universitario de Pontevedra from January 2015 to May 2022.

Article Synopsis
  • The zygomatic bone, crucial in facial anatomy, is prone to fractures from impacts like accidents and sports, and zygomatic implants may increase this risk.
  • A complex anatomical model using finite-element analysis (FEM) was created to simulate the zygomatic bone's behavior under various impact velocities.
  • Results indicated that higher speeds (15 and 20 km/h) caused severe crush fractures, while lower speeds led to less severe local damage, highlighting specific high-stress areas crucial for injury prevention.

Article Synopsis
  • The study focuses on comparing the effectiveness and safety of urea versus fluid restriction for treating hyponatraemia caused by SIADH in hospital patients.
  • An observational cohort study involving 212 patients showed that urea significantly increased sodium levels more than fluid restriction, with faster normalization of sodium levels (6 days vs. 8 days).
  • Additionally, the urea group had a lower 60-day mortality rate (16.1%) compared to the fluid restriction group (32.8%), highlighting urea’s better safety profile.

Background: Autism spectrum disorder (ASD) is a highly heterogeneous neurodevelopmental disorder whose etiology is not known today, but everything indicates that it is multifactorial. For example, genetic and epigenetic factors seem to be involved in the etiology of ASD. In recent years, there has been an increase in studies on the implications of gut microbiota (GM) on the behavior of children with ASD given that dysbiosis in GM may trigger the onset, development and progression of ASD through the microbiota-gut-brain axis.

Background: People with autism spectrum disorder (ASD) often struggle with gastrointestinal symptoms, implicating alterations of the gut-microbiota-brain axis, which has also been linked to sensory reactivity, pain, and gastro-intestinal symptoms in ASD. To better understand the prevalence and impact of gastrointestinal symptoms among individuals with ASD, a measure is needed that adhere to the Rome IV criteria of gastrointestinal symptoms and is applicable to individuals with ASD. The Gastrointestinal Symptom Severity Scale (GSSS) is a new assessment tool designed to match this need.

Objective: the aim of our study was to assess the effect of bariatric surgery on obstetric outcomes. Material and methods: a retrospective cohort study was conducted, including 54 pregnancies post-bariatric surgery and 219 pregnancies in non-operated obese women, from December 2018 to January 2023. Various maternal and obstetric characteristics were evaluated, ranging from baseline data to antepartum, intrapartum, postpartum, and neonatal outcomes.

  • * Results showed that patients who did not undergo spirometry experienced significantly higher rates of POC (48% vs. 11%) and mortality (18% vs. 0.4%) when categorized as high-risk based on ARISCAT levels.
  • * The findings suggest that incorporating preoperative spirometry into guidelines for patients with moderate or high ARISCAT risk could lead to better postoperative outcomes and lower mortality rates.

Background: This study aimed to validate the role of the D-dimer to lymphocyte ratio (DLR) for mortality prediction in a large national cohort of hospitalized coronavirus disease 2019 (COVID-19) patients.

Methods: A retrospective, multicenter, observational study that included hospitalized patients due to SARS-CoV-2 infection in Spain was conducted from March 2020 to March 2022. All biomarkers and laboratory indices analyzed were measured once at admission.

Functional gastrointestinal disorders (FGIDs) are a set of chronic or recurrent gastrointestinal symptoms (GS) with great psychobiological complexity. The appearance of FGIDs harms quality of life and drains medical resources. Psychometric properties of the Gastrointestinal Symptom Severity Scale (GSSS) based on Rome IV criteria were examined in a sample of 1247 individuals with typical development.

Functional gastrointestinal disorders (FGIDs) are characterized by chronic or recurrent gastrointestinal symptoms (GS) that are not explained by structural or biochemical abnormalities. FGIDs are related to lower quality of life, increased demands on medical resources, and greater somatization and emotional instability. Furthermore, GS appears to be an indicator of dysbiosis in gut-microbiota, affecting the gut-microbiota-brain relationship.

Background: Oral squamous cell carcinoma (OSCC) is characterized by an immunosuppressive tumor microenvironment. Their plasma-derived exosomes deliver immunomodulatory molecules and cargo that correlate significantly with clinical parameters. This study aims to assess the exosomal profile as a potential tool for early detection of relapse and long-term outcomes in OSCC patients undergoing conventional therapy.

Fabric permittivity is critical for the manufacturing of wearable sensors and antennas as well as predicting how fabrics interact with electromagnetic fields. Engineers should also understand how permittivity changes under different temperatures, densities, and moisture content values, or when several fabrics are mixed in aggregates, when designing future applications such as microwave dryers. The permittivity of cotton, polyester, and polyamide fabric aggregates is investigated in this paper for a wide range of compositions, moisture content levels, density values, and temperature conditions around the 2.
