Recurrent obstruction of biliary stent-in-stent: a heated solution.

Intraductal radiofrequency ablation (RFA) has been used in the management of malignant biliary obstruction and ampullary neoplasms. Some small studies refer to its role in managing benign biliary strictures with some promising results. The complications are not neglectable, namely cholangitis, pancreatitis, bleeding, and perforation, although most of them can be managed conservatively.

The effects of voluntary running on the skeletal muscle of rats with pulmonary arterial hypertension (PAH) were tested in the present study. PAH was induced in rats by a single injection of monocrotaline (MCT, 60 mg/kg). Rats in the sedentary hypertension (HS) group had their tolerance to physical exertion reduced throughout the experiment, while those in the sedentary control (SC), exercise control (EC), exercise hypertension (EH) and median exercise (EM) groups maintained or increased.

THE ROLE OF BOWEL DIARIES IN A "REAL-LIFE" SETTING.

Background: Despite the potential advantages of patients' self-recordings of bowel habits in lower digestive disorders, few studies evaluate the relevance of clinical information obtained through bowel diaries in clinical practice.

Objective: The main objective of this study was to evaluate the role of bowel diaries as an auxiliary diagnostic tool in lower gastrointestinal disorders consultations.

Methods: In this cross-sectional study, at the end of their gastroenterology consultation, patients were questioned about their bowel habits and gastrointestinal symptoms.

Transmural remission improves clinical outcomes up to 5 years in Crohn's disease.

Introduction: Evidence supporting transmural remission (TR) as a long-term treatment target in Crohn's disease (CD) is still unavailable. Less stringent but more reachable targets such as isolated endoscopic (IER) or radiologic remission (IRR) may also be acceptable options in the long-term.

Methods: Multicenter retrospective study including 404 CD patients evaluated by magnetic resonance enterography and colonoscopy.

The aim of the present study was to investigate whether possible awake bruxism (AB) is associated with the use of electronic devices and the practice of sports in schoolchildren aged eight to ten years. A cross-sectional study was conducted with 739 students in public and private schools in the city of Campina Grande, Brazil. Parents/guardians answered a questionnaire addressing sociodemographic data.

Impact of the COVID-19 pandemic on sleep quality and sleep bruxism in children eight to ten years of age.

This study aimed to determine the impact of the COVID-19 pandemic on sleep quality and possible sleep bruxism (SB) in children eight to ten years of age. The study hypothesis was that sleep disturbances influenced a higher occurrence of bruxism during the COVID-19 pandemic. A longitudinal study was conducted at two time points: in person prior to the COVID-19 pandemic (T1), and online during the pandemic (T2).

One appendix too many: a severe IBD-U case in remission after appendectomy.

A 39-year-old female was diagnosed with inflammatory bowel disease unclassified (IBD-U) in 2011, during the post-partum period, after developing chronic bloody diarrhea and marked weight loss. She underwent colonoscopy showing erosive ileitis and pancolitis. Biopsies were compatible with unspecified chronic ileocolitis.

Colitis due to Cytomegalovirus and Herpes Simplex Type 2 as a Complication of a First Presentation of Inflammatory Bowel Disease.

Introduction: The first presentation of ulcerative colitis may be an acute flare in about 15% of patients, requiring hospital admission. In acute severe steroid-refractory ulcerative colitis, cytomegalovirus (CMV) should be sought because it is a frequent cause of refractory disease. Herpes simplex colitis constitutes a rarer event in ulcerative colitis patients and it is usually associated with immunosuppression.

Cecal MALT lymphoma: a challenging diagnosis.

A 76-year-old female with a medical history of diabetes, arterial hypertension and dyslipidemia sought medical assistance due to left flank abdominal pain, fatigue and anorexia over the previous month. Laboratory analyses were normal and the computed tomography (CT) scan showed colonic diverticulosis and mesenteric panniculitis.

Validation of the IBD-Disk in a Portuguese cohort.

Objective: The aim of this study was to validate the IBD-Disk in a Portuguese cohort according to the COnsensus-based Standards for the selection of the health Measurement INstruments (COSMIN) recommendations.

Methods: After translation of the original IBD-Disk to Portuguese, a group of IBD patients was invited to complete the IBD-Disk at baseline (T0), after 1-4 weeks (T1) and after more than 3 months (T2), from July 2020 to February 2021. At T0 and T2, the patients also completed the IBD Disability Index.

COVID-19 in Gastroenterology Departments: The Impact of the First Wave.

Introduction: Coronavirus disease 2019 (COVID-19) is a global pandemic that has severely affected health care systems around the world. During the emergency state declared in Portugal in the months of March and April 2020, there was a severe reduction in medical activity in order to reduce the pressure on health systems. This study aimed to assess the impact of COVID-19 in gastroenterology departments across Portugal and the strategies developed to overcome this challenge.

Objective: Investigate the association between sleep disorders and probable sleep bruxism (SB) in children eight to ten years of age.

Methods: A cross-sectional study was conducted with 739 schoolchildren in Brazil. Parents/guardians answered a sociodemographic questionnaire, the sleep disturbance scale for children, and the Circadian Energy Scale.

Core temperature circadian rhythm across aging in Spontaneously Hypertensive Rats.

Unlabelled: The purpose of this study was to evaluate the circadian rhythm of core temperature (T) across aging in Spontaneously Hypertensive Rats (SHR) with comparison to the two rat strains often used as their normotensive control animals, namely, Wistar (WIS) and Wistar Kyoto (WKY).

Methods: WIS, WKY and SHR rats were subdivided into three different groups according their age: WIS16, WIS48, WIS72, WKY16, WKY48, WKY72, SHR16, SHR48 and SHR72 weeks-old. Body mass and blood pressure were periodically measured along the experiments.

β-hydroxy-β-methylbutyrate supplementation benefits the effects of resistance training on body fat reduction via increased irisin expression in white adipose tissue.

The effects of resistance training (RT) associated with calcium β-hydroxyβ-methylbutyrate (CaHMB) supplementation on the body composition and gene expression of cytokines related to skeletal muscle hypertrophy and adipose tissue metabolism were studied in rats. Male Wistar rats were divided into four groups of 12 animals: sedentary control (SC); sedentary supplemented (SS); resistance training control (RTC) and resistance training supplemented (RTS). Rats from RTC and RTS groups were submitted to an RT programme and those from SS and RTS groups received 1 mL of CaHMB (320 mg kg day) by gavage, for 8 weeks.

Clinical Performance of New Software to Automatically Detect Angioectasias in Small Bowel Capsule Endoscopy.

Background: Video capsule endoscopy (VCE) revolutionized the diagnosis and management of obscure gastrointestinal bleeding, though the rate of detection of small bowel lesions by the physician is still disappointing. Our group developed a novel algorithm (CMEMS-Uminho) to automatically detect angioectasias which display greater accuracy in VCE static frames than other methods previously published. We aimed to evaluate the algorithm overall performance and assess its diagnostic yield and usability in clinical practice.
