Electronic address:

Diagnosis of later-onset spinal muscular atrophy (SMA) can be challenging. This study aimed to evaluate the diagnostic properties of the detection of muscle fasciculations for SMA diagnosis in adolescents and adults with proximal muscle weakness. A cross-sectional diagnostic accuracy study was performed, in which 10 subjects with SMA (5 with type II and 5 with type III) and 9 subjects with genetic muscle diseases were evaluated by physical examination, muscle ultrasound (MUS) and electromyography (EMG).

Diagnostic performance of the RSNA-proposed classification for COVID-19 pneumonia versus pre-pandemic controls.

Braz J Infect Dis

March 2022

Radiology Department, Hospital de Clínicas de Porto Alegre (HCPA), RS, Brazil; Postgraduate Program in Pneumological Sciences, Universidade Federal do Rio Grande do Sul, RS, Brazil.

Objective: To evaluate the diagnostic accuracy of the Radiological Society of North America (RSNA) classification system for coronavirus disease 2019 (COVID-19) pneumonia compared to pre-pandemic chest computed tomography (CT) scan images to mitigate the risk of bias regarding the reference standard.

Materials And Methods: This was a retrospective, cross-sectional, diagnostic test accuracy study. Chest CT scans, carried out from May 1 to June 30, 2020, and from May 1 to July 17, 2017, were consecutively selected for the COVID-19 (positive reverse transcription-polymerase chain reaction [RT-PCR] for severe acute respiratory syndrome coronavirus 2 result) and control (pre-pandemic) groups, respectively.

Oxytocin Receptor Exon III Methylation in the Umbilical Cord Blood of Newborns With Prenatal Exposure to Crack Cocaine.

Front Cell Dev Biol

June 2021

Developmental Cognitive Neuroscience Lab, School of Medicine, Brain Institute of the Rio Grande do Sul (InsCer), Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS), Porto Alegre, Brazil.

Article Synopsis
  • - Prenatal cocaine exposure (PCE) can lead to long-term behavioral and cognitive issues in children, but research on its epigenetic impact, especially in humans, is limited.
  • - This study analyzed DNA methylation of the Oxytocin Receptor gene in umbilical cord blood from 28 newborns with PCE and 30 non-exposed newborns to see if there were significant differences.
  • - Findings showed no significant differences in methylation levels between the two groups, but highlighted that the severity of the mother's cocaine addiction influenced DNA methylation in newborns, pointing to the need for larger studies to further explore these effects.

Objective: To investigate whether increasing protein consumption to twice the recommended daily allowance (RDA) by The Institute of Medicine affects lean body mass (LBM), muscle strength, and physical performance in late postmenopausal women.

Methods: Parallel-group randomized trial with 26 apparently healthy women aged ≥ 65 years. Participants were randomly assigned to low-glycemic index diets with protein consumption at current RDA (0.

Treatment strategies for locally advanced hepatocellular carcinoma.

Transl Gastroenterol Hepatol

February 2019

Digestive Surgery Division, Universidade Federal de Ciências da Saúde de Porto Alegre (UFCSPA), Porto Alegre, RS, Brazil.

Article Synopsis
  • Liver cancer is a major health issue, ranking fifth in incidence and fourth in cancer-related deaths globally, with about 854,000 new cases and 810,000 deaths annually, predominantly from hepatocellular carcinoma (HCC).
  • There are various staging systems to assess HCC, but the lack of a unified definition for advanced disease complicates treatment and prognosis, leading to ongoing debate in the medical community.
  • Treatment options for advanced HCC include curative methods like transplantation and resection, as well as locoregional and systemic therapies, which should be tailored for each patient through a multidisciplinary approach.

Unlabelled: Objetive: The aim of this study was to characterize the acoustic signal of silent tracheal aspiration in children with oropharyngeal dysphagia (OPD).

Method: Thirty-two children with OPD were examined with combined digital cervical auscultation (DCA) and videofluoroscopic swallow study (VFSS). Power spectral density (PSD, in 1/√Hz) of the acoustic signal from a sequential series of five liquid swallows was used for comparisons between children who silently aspirated and children who did not aspirate on VFSS.

Non-Answered Questions in Patients with Endobronchial Valve Placement for Lung Volume Reduction.

Respiration

October 2018

Unit of Interventional Pulmonology, Clínica Alemana de Santiago, Facultad de Medicina Clínica Alemana - Universidad del Desarrollo, Santiago, Chile.

Endoscopic lung volume reduction is a minimally invasive procedure performed to reduce the space occupied by the emphysemas' lobes. This procedure has been demonstrated to be beneficial for patients with advanced chronic obstructive pulmonary disease and severe hyperinflation. The use of endobronchial valves is increasing, as well as the number of reports of adverse events.

Accuracy of clinical swallowing evaluation for diagnosis of dysphagia in children with laryngomalacia or glossoptosis.

Pediatr Pulmonol

January 2017

Pediatric Pulmonology Unit, Department of Pediatrics, HCPA, Programa de Pós-Graduação em Saúde da Criança e do Adolescente, School of Medicine, UFRGS, Porto Alegre, RS, Brazil.

Objective: To investigate the accuracy of clinical evaluation of swallowing in a sample of children with laryngomalacia or glossoptosis and describe the prevalence of dysphagia in each of these diseases, as well as characterize the swallow response to speech and language therapy interventions.

Study Design: Children aged 1 month to 11 years receiving care at the Department of Otolaryngology, Hospital de Clínicas de Porto Alegre, Brazil, were evaluated in a cross-sectional design. Evaluation of swallowing was performed at two time points by two blinded speech-language pathologists, one responsible for clinical evaluation and the other for videofluoroscopic study.

Background: The aim of this study was to investigate whether body composition, dietary pattern and habitual physical activity are associated with BMD according to time since menopause in women from Southern Brazil with no clinical evidence of disease.

Methods: 99 participants were enrolled and anthropometry, body composition and BMD by dual energy x-ray absorptiometry, rest metabolic rate by indirect calorimetry, dietary pattern by semi quantitative food frequency questionnaire and habitual physical activity by pedometer were performed.

Results: Mean age was 55.

The authors report the case of an elderly woman assessed for dyspnea and right costal margin pain, whose chest radiography demonstrated opacity simulating pulmonary lesion, and computed tomography revealed the vascular origin of the condition. Acute aortic syndrome due to ruptured atheromatous plaque penetrating through the elastic lamina in association with aortic hematoma and aneurysm is a relevant differential diagnosis to be considered in these cases.

Lean muscle mass in classic or ovulatory PCOS: association with central obesity and insulin resistance.

Exp Clin Endocrinol Diabetes

October 2012

Gynecological Endocrinology Unit, Division of Endocrinology, Hospital de Clínicas de Porto Alegre (HCPA), Porto Alegre, Brazil.

This age-matched case-control study assessed total and segmental lean muscle mass in classic or ovulatory polycystic ovary syndrome (PCOS) patients and investigated whether lean mass is associated with hormone and metabolic features. Participants underwent anthropometric and clinical evaluation. Habitual physical activity was assessed with a digital pedometer, and body composition by dual-energy X-ray absorptiometry.
