The progress in evidence of the effectiveness of preventive repositioning in the appearance of these lesions in vulnerable hospitalized patients is also evaluated.
Methods: Databases were reviewed in non-systematic manner, including the Cochrane Wounds Specialized Register; Medline, Scopus, PubMed, the Cochrane Central Register of Controlled Trials; MEDLINE (Ovid); EMBASE (Ovid), Web of Science, SciELO, and Lilacs.
Introduction: Patients undergoing vascular procedures are prone to developing postoperative complications affecting their short‑term mortality. Prospective reports describing the incidence of long‑term complications after vascular surgery are lacking.
Objectives: We aimed to describe the incidence of complications 1 year after vascular surgery and to evaluate an association between myocardial injury after noncardiac surgery (MINS) and 1‑year mortality.
It is uncertain whether hydrocolloid dressings, a more costly intervention than offering standard care with petrolatum, is superior to prevent pressure ulcers among hospitalized high-risk adults. Randomized, parallel-group, open-label, superiority trial with an active control group, blinded for investigators, event validators, and analysts (December 1, 2015 to December 12, 2017). Eligible patients were ≥ 18 years of age with intact skin judged as high-risk for skin ulcers (Braden scale), admitted to surgical or medical wards of two tertiary-level hospitals.

The authors set out to describe outcomes after discharge from hospital up to 1 yr after inpatient noncardiac surgery and associations between predischarge complications and postdischarge death up to 1 yr after surgery.
Methods: This study was an analysis of patients discharged after inpatient noncardiac surgery in a large international prospective cohort study across 28 centers from 2007 to 2013 of patients aged 45 yr or older followed to 1 yr after surgery.
Background: Intra-hospital falls have become an important public health problem globally. The use of movement sensors with alarms has been studied as elements with predictive capacity for falls at hospital level. However, in spite of their use in some hospitals throughout the world, evidence is lacking about their effectiveness in reducing intra-hospital falls.

The aim of this study was to evaluate the impact of pre-surgical walking in-hospital length of stay, early ambulation, and the appearance of complications after surgery among patients scheduled for non-cardiac surgery.
Methods: A two-arm, single- blinded randomized controlled trial was developed from May 2016 to August 2017.
Background: Despite being considered preventable, ulcers due to pressure affect between 30 and 50% of patients at high and very high risk and susceptibility, especially those hospitalized under critical care. Despite a lack of evidence over the efficacy in prevention against ulcers due to pressure, hourly repositioning in critical care as an intervention is used with more or less frequency to alleviate pressure on patients' tissues. This brings up the objective of our study, which is to evaluate the efficacy in prevention of ulcers due to pressure acquired during hospitalization, specifically regarding two frequency levels of repositioning or manual posture switching in adults hospitalized in different intensive care units in different Colombian hospitals.

Methods: This was a retrospective descriptive study based on medical records of 1,210 patients who received insertion of vascular access devices by the specialized group of nurses. Result indicators are described.
Objectives: To describe the clinical characteristics, treatment, evolution, and nursing care of adult patients with severe acute respiratory distress syndrome who were positive for SARS-CoV-2 and hospitalized in intensive care units (ICUs) during the first peak of the pandemic in Colombia, 2020.
Methods: Multicenter descriptive study of four high-complexity hospitals in Colombia, which included 473 consecutive adult patients admitted to intensive care units with a confirmed diagnosis of SARS CoV-2. Sociodemographic and clinical information - comorbidities, treatment and evolution - and nursing care provided were included.
Background: Among adults undergoing contemporary noncardiac surgery, little is known about the frequency and timing of death and the associations between perioperative complications and mortality. We aimed to establish the frequency and timing of death and its association with perioperative complications.
Methods: We conducted a prospective cohort study of patients aged 45 years and older who underwent inpatient noncardiac surgery at 28 centres in 14 countries.
Article Synopsis
- The study aimed to assess how mobilization strategies affect physical function in hospitalized adults with medical conditions.
- A systematic review and meta-analysis were conducted, analyzing data from 13 randomized controlled trials involving 2,703 participants, which revealed that mobilization significantly improved patients' physical function and reduced hospital stays.
- The findings suggest that implementing effective mobilization techniques could enhance the overall health outcomes for hospitalized patients, benefiting both patients and healthcare providers.
Objectives: This work sought to assess the inter-observer agreement among expert nurses by using digital photographs and between these experts and the nursing registries in the electronic clinical record in the identification and degree of PL.
Methods: This was an observational study, including 225 photographic records (184 patients, 97 with pressure lesion and 128 registries without lesion) randomly selected from the total of photographs registered in the PENFUP clinical trial (without lesion). Three expert evaluators assessed said photographs in masked manner.
Objectives: This work sought to evaluate the association between using preventive hydrocolloid dressings and the onset of pressure ulcers in hospitalized patients.
Methods: Retrospective cohort study that included adult patients with high risk of pressure ulcers (PU) evaluated according to the Braden scale and who had been admitted with preventive purposes to a skin care program. The preventive care prescribed by the nursing staff included using hydrocolloid dressing plus conventional care (HD+CC) or only conventional care (CC), in a tier IV hospital in Bogotá, Colombia.
Purpose: The aim of this study was to determine the prevalence of physical inactivity and its associated factors in adult patients admitted to hospital for noncardiac surgery.
Design: Cross-sectional study.
Methods: Five hundred able-bodied patients (age ≥45 years) admitted to hospital, also participants in the VISION study, were recruited before noncardiac surgery.
Objective: To determine the prognostic relevance, clinical characteristics, and 30-day outcomes associated with myocardial injury after noncardiac surgery (MINS) in vascular surgical patients.
Background: MINS has been independently associated with 30-day mortality after noncardiac surgery. The characteristics and prognostic importance of MINS in vascular surgery patients are poorly described.
Importance: Little is known about the relationship between perioperative high-sensitivity troponin T (hsTnT) measurements and 30-day mortality and myocardial injury after noncardiac surgery (MINS).
Objective: To determine the association between perioperative hsTnT measurements and 30-day mortality and potential diagnostic criteria for MINS (ie, myocardial injury due to ischemia associated with 30-day mortality).
Design, Setting, And Participants: Prospective cohort study of patients aged 45 years or older who underwent inpatient noncardiac surgery and had a postoperative hsTnT measurement.

Background: Prevention of chronic chagasic cardiomyopathy (CCC) by treating infected populations with trypanocidal therapy (TT) remains a challenge. Despite a renewed enthusiasm for TT, uncertainty regarding its efficacy, concerns about its safety and limited availability remain barriers for a wider use of conventional drugs. We have updated a previous version of this review.
View Article and Find Full Text PDFBackground: Myocardial injury after noncardiac surgery (MINS) was defined as prognostically relevant myocardial injury due to ischemia that occurs during or within 30 days after noncardiac surgery. The study's four objectives were to determine the diagnostic criteria, characteristics, predictors, and 30-day outcomes of MINS.
Methods: In this international, prospective cohort study of 15,065 patients aged 45 yr or older who underwent in-patient noncardiac surgery, troponin T was measured during the first 3 postoperative days.
This study was aimed to identify the mobilization patterns of acute myocardial infarction (AMI) patients during their first three days in the coronary care unit (CCU) by performing a prospective observational pilot study design. The study included 31 diagnosed AMI patients admitted to three CCUs. Mobilization patterns classified as bed rest, semi-fowler, transfer to chair, and standing/walking were documented by CCU nurses for 72 consecutive hours after patient admission to the CCU.
