Introduction: Patients with familial adenomatous polyposis (FAP) are characterised by the appearance of colorectal cancer if the disease is left to follow its natural course, which means they frequently undergo prophylactic colectomy at a young age. In these patients, duodenal cancer becomes the leading cause of death, which deems surveillance necessary. Gastric cancer, although rare, can also occur in these patients, and total gastrectomy is the usual treatment option.

This investigation's novelty and objective reside in exploring catalytic flash pyrolysis of cross-linked polyethylene (XLPE) plastic residue in the presence of kaolin, with the perspective of achieving sustainable production of gasoline-range hydrocarbons. Through proximate analysis, thermogravimetric analysis, and heating value determination, this study also assessed the energy-related characteristics of cross-linked polyethylene plastic residue, revealing its potential as an energy source (44.58 MJ kg) and suitable raw material for pyrolysis due to its low ash content and high volatile matter content.

Purpose: The objective of this study is to compare the operative time, intraoperative complications, length of stay, readmission rates, overall complications, mortality, and cost associated with Robotic Surgery (RS) and Laparascopic Surgery (LS) in anti-reflux and hiatal hernia surgery.

Methods: A comprehensive literature search was conducted using MEDLINE (via PubMed), Web of Science and Scopus databases. Studies comparing short-term outcomes and cost between RS and LS in patients with anti-reflux and hiatal hernia were included.

Epithelioid hemangioendothelioma is a very rare vascular neoplasm, which is often multifocal or metastatic at diagnosis. Most frequently arises in the liver, followed by the lung and bones. The authors present a case of a liver transplant recipient who developed a pattern of hepatic cholestasis associated with the appearance of a proliferative hepatic lesion with infiltrative growth.

Introduction: Wilson's disease (WD) is associated with a variety of movement disorders and progressive neurological dysfunction. The aim of this study was to correlate baseline brain magnetic resonance imaging (MRI) features with clinical phenotype and long-term outcomes in chronically treated WD patients.

Methods: Patients were retrospectively selected from an institutional database.

Article Synopsis
  • * A study of 259 older adults (153 women, 106 men) in Guarda, Portugal, found common barriers to PA, with women facing more intrinsic challenges like fear of injury, while men reported worse health status.
  • * Strategies to improve active aging should target specific intrinsic and extrinsic barriers based on gender and different dimensions of physical activity to encourage more participation among older adults.

The main goals of this study were to identify profiles in school-aged children based on actual Motor Competence (MC) and accuracy of Perceived Motor Competence (PMC) and to examine how children with different profiles differ in terms of Physical Fitness (PF) and Body Fat percentage (BF%). The MC of a total of 287 children (51.6% boys, aged between 6 and 10 years-old) was assessed using the Motor Competence Assessment (MCA) instrument, and the accuracy of the PMC was measured using motor tasks (standing long jump, throwing, kicking, and walking backwards).

Brain manganese (Mn) accumulation is a key feature in patients with acquired hepatocerebral degeneration (AHD). The role of trace elements other than Mn in AHD needs to be clarified. In this study, using inductively coupled plasma mass spectrometry, we aimed to evaluate blood levels of trace elements in patients with AHD before and after liver transplantation (LT).

Background: Surgical resection represents the main treatment for resectable nonmetastatic gastric gastrointestinal stromal tumors. Despite the feasibility and safety of laparoscopic resection, its standard use in gastric tumors larger than 5 cm is yet to be established.

Aims: This study aimed to compare the current evidence on laparoscopic resection with the classical open surgical approach in terms of perioperative, postoperative, and oncological outcomes.

We investigated whether the relationship between significant others' social support and adolescents' physical activity (PA) is mediated by perceived barriers and benefits of PA. In this cross-sectional study, we analyzed data from 497 adolescents (girls = 272, boys = 225) aged between 12-18 years ( = 15.87, = 1.

Article Synopsis
  • The study explored how motor skill proficiency affects cardiorespiratory (CRF) and musculoskeletal (MSF) fitness in a sample of 241 youth aged 10-18, categorizing motor competence (MC) levels into low, moderate, and high.
  • Significant findings showed that low motor proficiency was linked to poor CRF, as none of the low-skilled youth achieved "Healthy" standards on the PACER test.
  • While there was some evidence of a proficiency barrier for MSF, as high MC individuals consistently displayed at least moderate grip strength, about 20.8% of those with low MC still achieved high grip strength, indicating a less clear relationship.

The Motor Competence Assessment (MCA) is a quantitative test battery that assesses motor competence across the whole lifespan. It is composed of three sub-scales: locomotor, stability, and manipulative, each of them assessed by two different objectively measured tests. The MCA construct validity for children and adolescents, having normative values from 3 to 23 years of age, and the configural invariance between age groups, were recently established.

Children’s motor competence (MC) was negatively affected by the COVID-19 pandemic; however, possible chronic effects have not been studied. Therefore, the aim of this study was to examine the possible impact of the forced lack of physical activity (PA) during the COVID-19 lockdown on children’s MC two years later. The motor competence of sixty-seven healthy children (7.

The Carnitine Palmitoyltranferase I (CPT1) catalyzes the rate-limiting step of long-chain fatty acid (LCFA) mitochondrial β-oxidation. The enzyme promotes the conjugation of LCFA with l-carnitine, which allows LCFA to enter the mitochondria matrix. The structural features involved in CPT1 and LCFA-CoA interactions have not been fully elucidated, mainly due to the absence of CPT1 crystallographic data.

Introduction: In 2008, a conceptual model explaining the role of motor competence (MC) in children's physical activity (PA), weight status, perceived MC and health-related fitness was published.

Objective: The purpose of the current review was to systematically compile mediation, longitudinal and experimental evidence in support of this conceptual model.

Methods: This systematic review (registered with PROSPERO on 28 April 2020) was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement.

The purpose of this study was to assess the effect of somatic and socio-cultural factors on children's motor competence (MC). MC was assessed through the standing long jump (SLJ), distance throw of a tennis ball (TTB), and 20 m dash (20 m) in 181 children (84 girls) with a mean age of 6.10(0.

The number of single-child families has been rising steadily in recent years, resulting in a childhood absent of sibling relationships. Being an only child has been shown to have a negative impact on physical fitness, somatic fitness, and motor development. In this study, we aimed to understand how living with and without siblings can impact the motor competence of children.

Acoustic Doppler Current Profiler (ADCP) sensors measure water inflows and are essential to evaluate the Flow Curve (FC) of rivers. The FC is used to calibrate hydrological models responsible for planning the electrical dispatch of all power plants in several countries. Therefore, errors in those measures propagate to the final energy cost evaluation.

Article Synopsis
  • The study investigated how taking a break from training affects young swimmers' performance, body measurements, and swimming techniques.
  • It included 54 swimmers (22 boys and 32 girls) and found that both groups experienced performance declines in the 100 m freestyle by about 2.17% for boys and 1.91% for girls during a season break.
  • Despite these performance dips, both boys and girls saw increases in body measurements, with height specifically helping to mitigate performance losses. *
