Accuracy of duplex ultrasonography versus angiotomography for the diagnosis of extracranial internal carotid stenosis.

Introduction: Internal carotid artery (ICA) stenosis causes about 15% of ischemic strokes. Duplex ultrasonography (DUS) is the first line of investigation of ICA stenosis, but its accuracy varies in the literature and it is usual to complement the study with another more accurate exam when faced with significant stenosis. There is a lack of studies that compare DUS with angiotomography (CTA) in the present literature.

External validation of Villalta score in high-middle income country patients with deep vein thrombosis.

Post-thrombotic syndrome (PTS) is a late complication that does not have a cure yet, with a prevalence estimated between 20 to 75%, associated with previous deep vein thrombosis event. Although the Villalta score (VS) is the gold-standard clinical tool for diagnostic and prognostic evaluation of PTS, there are currently no VS intra-rater agreement established and no validation studies for VS' application into Brazilian Portuguese. We sought to translate and validate VS reliability systematically; and, secondarily, to compare the ultrasound findings with the severity of PTS.

Ventilatory weaning strategies for predicting extubation success in children following cardiac surgery for congenital heart disease: a protocol for a systematic review and meta-analysis.

Introduction: Congenital heart disease (CHD) comprises the anatomic malformations that jeopardise the structure and function of the heart. It can be extremely complex and serious, corresponding to 30% of all deaths in the first month of life. The surgical approach for adequate treatment requires postoperative mechanical ventilation.

Early mobilization for children in intensive therapy: A protocol for systematic review and meta-analysis.

Introduction: Intensive care units focus primarily on life support and treatment of critically ill patients, but there are many survivors with complications, such as generalized muscle disorders, functional disability and reduced quality of life after hospital discharge, resulting from prolonged stays in these units. The current evidence suggests that early mobilization-based rehabilitation (exercise initiated immediately after the patient's significant physiological changes have stabilized) in critically ill adults can alleviate these complications from immobility and critical illness. However, there are a lack of practice guidelines, conflicting perceptions about safety, and knowledge gaps about benefits in the critically ill paediatric population.

Peripherally inserted central catheter versus central venous catheter for intravenous access: A protocol for systematic review and meta-analysis.

Background: Since the first description of the central venous catheter (CVC) in 1952, it has been used for the rapid administration of drugs, chemotherapy, as a route for nutritional support, blood components, monitoring patients, or combinations of these. When CVC is used in the traditional routes (eg, subclavian, jugular, and femoral veins), the complication rates range up to 15% and are mainly due to mechanical dysfunction, infection, and thrombosis. The peripherally inserted central catheter (PICC) is an alternative option for CVC access.

Angioplasty and stenting for below the knee ulcers in diabetic patients: protocol for a systematic review.

Background: The worldwide incidence and prevalence of diabetes mellitus (DM) are increasing. DM has a high social and economic burden due to its complications and associated disorders. Peripheral arterial disease (PAD) is closely related to DM.

Thighplasty after bariatric surgery: evaluation of lymphatic drainage in lower extremities.

Background: Bariatric surgery for morbid obesity achieves an accentuated weight loss, with skin and soft tissue redundancy in some corporal segments, including the thighs. The thigh lift is a plastic surgery that improves this redundant tissue in the medial thigh area, but this surgical procedure may have complications, such as inferior migration of the scar, delayed wound healing, vulvar distortion, and lymphatic system alterations.

Methods: To evaluate the effect of the thighplasty on the lymphatic system, 14 patients were prospectively included in this study.

Analysis of the effects of the interruption of the flow in the normal arterial endothelium morphology and the correlation with the ischemia duration in rabbits.

Unlabelled: The study of acute arterial insufficiency of the extremities is an area of continuing interest and investigation, in light of the possible effects stemming from the evolution of the disease and the necessity for urgent treatment.

Purpose: To analyze the effects of the interruption of the flow in the normal arterial endothelium morphology and correlate them with the ischemia duration.

Methods: We submitted 30 rabbits to the ligature of the right external iliac artery for 6 hours or 72 hours and observed specific morphological variables in the endothelial layer under optical and electronic microscopy.
