The different impacts of COVID-19 on the mental health of distinct health care worker categories.

The present study sought to explore the factors associated with the odds of having probable depression and posttraumatic stress disorder (PTSD) related to traumatic COVID-19 experiences and their impact on health care workers in distinct categories. In this cross-sectional study, 1843 health care workers (nurses, nurse technicians, physicians, physical therapists, and other healthcare workers) were recruited via convenience sampling. A survey was administered to obtain information regarding sociodemographic, occupational, and mental health status.

Tonic immobility is associated with posttraumatic stress symptoms in healthcare professionals exposed to COVID-19-related trauma.

The Coronavirus Disease 2019 (COVID-19) pandemic has exposed healthcare workers (HCW) to traumatic situations that might lead to the development of posttraumatic stress disorder (PTSD). An important vulnerability factor for PTSD is the peritraumatic tonic immobility (TI) reaction, an involuntary and reflexive defensive response evoked by an intense and inescapable threat. TI is largely understudied in humans and has not been investigated during trauma related to COVID-19.

Impact of surgical checklist and its completion on complications and mortality in urgent colorectal procedures.

Objective: to assess the impact of using a surgical checklist and its completion on complications such as surgical site infection (SSI), reoperation, readmission, and mortality in patients subjected to urgent colorectal procedures, as well as the reasons for non adherence to this instrument in this scenario, in a university hospital in Ottawa, Canada.

Methods: this is a retrospective, epidemiological study. We collected data from an electronic database containing information on patients undergoing urgent colorectal operations, and analyzed the occurrence of SSI, reoperation, readmission, and death in a 30 day period, as well as the completion of the checklist.

Vulnerability and Protective Factors for PTSD and Depression Symptoms Among Healthcare Workers During COVID-19: A Machine Learning Approach.

Healthcare workers are at high risk for developing mental health problems during the COVID-19 pandemic. There is an urgent need to identify vulnerability and protective factors related to the severity of psychiatric symptoms among healthcare workers to implement targeted prevention and intervention programs to reduce the mental health burden worldwide during COVID-19. The present study aimed to apply a machine learning approach to predict depression and PTSD symptoms based on psychometric questions that assessed: (1) the level of stress due to being isolated from one's family; (2) professional recognition before and during the pandemic; and (3) altruistic acceptance of risk during the COVID-19 pandemic among healthcare workers.

Impact of surgical checklist and its completion on complications and mortality in urgent colorectal procedures.

Objective: to assess the impact of using a surgical checklist and its completion on complications such as surgical site infection (SSI), reoperation, readmission, and mortality in patients subjected to urgent colorectal procedures, as well as the reasons for non adherence to this instrument in this scenario, in a university hospital in Ottawa, Canada.

Methods: this is a retrospective, epidemiological study. We collected data from an electronic database containing information on patients undergoing urgent colorectal operations, and analyzed the occurrence of SSI, reoperation, readmission, and death in a 30 day period, as well as the completion of the checklist.

Tonic Immobility is Associated with PTSD Symptoms in Traumatized Adolescents.

Purpose: Growing evidence suggests that peritraumatic tonic immobility, an involuntary defensive response that involves extreme physical immobility and the perceived inability to escape, is a significant predictor of post-traumatic stress disorder (PTSD) symptomatology. However, this issue has not been specifically addressed in adolescents. Here, we investigated whether tonic immobility response experienced during the worst childhood or adolescent trauma is associated with PTSD symptom severity in a non-clinical student sample.

The invisible scars of emotional abuse: a common and highly harmful form of childhood maltreatment.

Background: Childhood maltreatment (CM) is unfortunately widespread globally and has been linked with an increased risk of a variety of psychiatric disorders in adults, including posttraumatic stress disorder (PTSD). These associations are well established in the literature for some maltreatment forms, such as sexual and physical abuse. However, the effects of emotional maltreatment are much less explored, even though this type figures among the most common forms of childhood maltreatment.

Hidden wounds of violence: Abnormal motor oscillatory brain activity is related to posttraumatic stress symptoms.

Victims of urban violence are at risk of developing Posttraumatic Stress Disorder (PTSD), one of the most debilitating consequences of violence. Considering that PTSD may be associated with inefficient selection of defensive responses, it is important to understand the relation between motor processing and PTSD. The present study aims to investigate the extent to which the severity of posttraumatic stress symptoms (PTSS) is related to motor preparation against visual threat cues in victims of urban violence.

Impact of Surgical Checklist on Mortality, Reoperation, and Readmission Rates in Brazil, a Developing Country, and Canada, a Developed Country.

Purpose: To compare the mortality, reoperation, and readmission rates before and after the implementation of a surgical checklist in Brazil and Canada.

Design: An epidemiological, retrospective study was conducted.

Methods: Preimplementation and postimplementation data were collected via patient chart reviews to determine mortality, reoperation, and readmission rates.

Effect of surgical safety checklist on colorectal surgical site infection rates in 2 countries: Brazil and Canada.

Background: The effectiveness of the surgical safety checklist (SSC) in countries with different socioeconomic backgrounds is uncertain. To evaluate the effect of the SSC in 2 different socioeconomic settings, we compared surgical site infection (SSI) rates before and after its implementation in colorectal procedures.

Methods: An epidemiological retrospective study was conducted in the university hospitals in Ottawa, Canada, and Belo Horizonte, Brazil.

Adherence and factors related to acceptance of alcohol for antiseptic hand rubbing among nursing professionals.

Objective: Identify rates of adhesion and related factors to acceptance of an alcohol based preparation to hands antiseptic friction among nursing professionals in a unit of intensive therapy.

Method: A cross-sectional study, which involved direct observation of hand hygiene opportunities and nursing professionals' completion of questionnaires, was conducted at a university hospital between January and July 2015. Descriptive and univariate analyses were performed, with a 5% significance level.

[Evaluation of adherence to measures for the prevention of surgical site infections by the surgical team].

Objective: Evaluate pre- and intraoperative practices adopted by medical and nursing teams for the prevention of surgical infections.

Method: A prospective study carried out in the period of April to May 2013, in a surgical center of a university hospital in Belo Horizonte, Minas Gerais.

Results: 18 surgeries were followed and 214 surgical gloves were analyzed, of which 23 (10.

Evaluation of surgical glove integrity during surgery in a Brazilian teaching hospital.

Background: A cross-sectional study was conducted in a large university hospital in Belo Horizonte, Minas Gerais, Brazil to evaluate surgical glove integrity after use during surgery.

Methods: This 6-month study was conducted by a gastroenterological, cardiovascular, and pediatric surgical team consisting of surgeons (main surgeon and first and second assistants), medical students, and scrub nurses. The gloves used during surgery were examined postsurgery for microperforations using the watertight test as described in European Norm EN 455-1.
