Effects of Whole-Body Vibration Exercises on Muscle Responses and on Risk of Falls in Elderly Individuals: A Systematic Review.

Background: This systematic review was conducted to assess the effects of whole-body vibration (WBV) exercises on muscles responses and on risk of falls in elderly individuals.

Methods: Searches were conducted in MEDLINE/PubMed, Physiotherapy Evidence Database (PEDro), Web of Science, CINAHL and Scopus databases in Feb 2023 to identify studies with the potential to be included according to the eligibility criteria. Relevant data from included studies were extracted.

Fast-track versus conventional surgery in relation to time of hospital discharge following total hip arthroplasty: a single-center prospective study.

Background: Total hip arthroplasty (THA) has been used for over five decades for treating hip osteoarthritis. THA is a surgical procedure associated with prolonged hospital length of stay (LOS). The aim of this study was to analyze whether a protocol developed for fast-track THA could decrease the time taken to reach functional recovery after surgery and the hospital LOS.

COVID-19 and Myocardial Injury in a Brazilian ICU: High Incidence and Higher Risk of In-Hospital Mortality.

Background: The incidence of myocardial injury (MI) in patients with COVID-19 in Brazil and the prognostic impact of MI have not been elucidated.

Objectives: To describe the incidence of MI in patients with COVID-19 in the intensive care unit (ICU) and to identify variables associated with its occurrence. The secondary objective was to assess high-sensitivity troponin I as a predictor of in-hospital mortality.

Viscossuplementation for the treatment of osteoarthritis of the knee: A protocol for an umbrella review of systematic reviews with meta-analyses of randomized controlled trials.

Background: Knee osteoarthritis (KOA) is a common chronic disease with worldwide prevalence of 10% to 79%, with costs ranging from $560 to $635 billion for year in United States of America. The main guidelines recommend interventions with undesirable adverse events (AE) or highly dependent on the patient's persistence. Thus, intra-articular (IA) therapies appear to be attractive in patients with KOA, as well as a valid therapy by maximizing effects locally in the joint and limiting systemic AE.

Validation of the Brazilian version of the Hip Outcome Score (HOS) questionnaire.

Background: The Hip Outcome Score (HOS) was developed to evaluate physically active patients with hip disease but without severe degenerative change. A translation and cultural adaptation into Brazilian Portuguese was previously conducted. The aim of this study was to validate the Brazilian version of the HOS (HOS-Brazil) among a group of physically active patients with a diagnosis of femoroacetabular impingement (FAI) or greater trochanteric pain syndrome (GTPS).

Spatiotemporal expression of extracellular matrix components during the chondrogenic and osteogenic phases of bone healing.

In this study, we investigated the cascade of events involved in the early phases of bone healing in rats, especially the transition from chondrogenesis to osteogenesis, which involves cellular and extracellular matrix (ECM) components. We used a standardized closed tibial fracture model in Wistar rats, which was divided into nine groups of five animals each, and the fracture area was evaluated at 0, 12, 24, 48, 72, 96, 144, 192, and 240 hours post-injury. Histological, histochemical, immunohistochemical and morphometric techniques were used to evaluate the proliferating cell nuclear antigen (PCNA), transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), type I procollagen (procoll-I), type I collagen (coll-I), and type II collagen (coll-II) expression at every time point.

Translation and cultural adaptation of the Hip Outcome Score to the Portuguese language.

Objective: to translate the Hip Outcome Score clinical evaluation questionnaire into Portuguese and culturally adapt it for Brazil.

Methods: the Hip Outcome Score questionnaire was translated into Portuguese following the methodology consisting of the steps of translation, back-translation, pretesting and final translation.

Results: the pretesting was applied to 30 patients with hip pain without arthrosis.

Medial hip arthroscopy portals: an anatomic study.

Purpose: The main objective of this study was to investigate medial hip portals and evaluate their relation with anatomic structures in a cadaveric model.

Methods: Placement of 3 medial arthroscopic portals was simulated in 10 fresh human paired cadaveric hip specimens by placing Steinmann pins into the joint under fluoroscopic control. Two portals were made at the groin, 1 anterior and 1 posterior to the adductor longus muscle, and the third portal was placed posterior to the adductor longus muscle, 5 cm distal to the groin.
