Association between attention performance and the different dimensions of DSM-5 depression symptoms.

Objective: Depressive symptoms can be assessed with self-reported questionnaires, such as the Patient Health Questionary-9 (PHQ-9). Previous studies have suggested that the PHQ-9 items can be grouped into somatic and non-somatic clusters. However, the classification of the PHQ-9 item "concentration difficulties" into somatic or non-somatic is still controversial.

New Insights on the Mechanisms of Myocardial Injury in Hypertensive Patients With COVID-19.

Purpose: Myocardial injury is common in hypertensive patients with 2019 coronavirus disease (COVID-19). Immune dysregulation could be associated to cardiac injury in these patients, but the underlying mechanism has not been fully elucidated.

Methods: All patients were selected prospectively from a multicenter registry of adults hospitalized with confirmed COVID-19.

Spirituality as a protective factor for chronic and acute anxiety in Brazilian healthcare workers during the COVID-19 outbreak.

Background: Anxiety symptoms (AS) are exacerbated in healthcare workers (HCWs) during the COVID-19 pandemic. Spirituality is known to protect against AS in the general population and it is a construct that differs from religion. It can be assessed using structured questionnaires.

Assessment of Attentional Functioning in Health Professionals of a Brazilian Tertiary Referral Hospital for COVID-19.

This study is aimed at assessing differences in basic attentional functioning between substantial and minimal work-related exposure to COVID-19 patients in professionals working in a tertiary referral hospital in Rio de Janeiro, Brazil. Therefore, hospital employees performed a Continuous Visual Attention Test. This test consisted of a 90-second Go/No-Go task with 72 (80%) targets and 18 (20%) nontargets.

Analysis of Posterior Tibial Slope as Risk Factor to Anterior Cruciate Ligament Tear.

 The objective of the present study was to evaluate the relationship between patients with anterior cruciate ligament (ACL) injury by indirect trauma and increased posterior tibial inclination.  Retrospective study, performed by analysis of medical records and digital radiographs of patients, present in a database of a tertiary orthopedic hospital. The sample consisted of two groups, the first group consisting of patients diagnosed with ACL injury by indirect trauma, and a control group matched by age.

Takotsubo Multicenter Registry (REMUTA) - Clinical Aspects, In-Hospital Outcomes, and Long-Term Mortality.

Background: Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil.

Surgical Treatment for Chronic Rupture of the Patellar Tendon Performed in 2 Stages.

Patellar tendon rupture is an uncommon but disabling lesion. It usually occurs in men younger than 40 years, through direct or indirect trauma. Obtaining satisfactory results with treatment of chronic injuries and re-ruptures in which the patella retracts owing to quadriceps contraction is a challenge.

Prediction of major cardiac events after vascular surgery.

Objective: Predicting cardiac events is essential to provide patients with the best medical care and to assess the risk-benefit ratio of surgical procedures. The aim of our study was to evaluate the performance of the Revised Cardiac Risk Index (Lee) and the Vascular Study Group of New England Cardiac Risk Index (VSG) scores for the prediction of major cardiac events in unselected patients undergoing arterial surgery and to determine whether the inclusion of additional risk factors improved their accuracy.

Methods: The study prospectively enrolled 954 consecutive patients undergoing arterial vascular surgery, and the Lee and VSG scores were calculated.

Impact of cardiology referral: clinical outcomes and factors associated with physicians' adherence to recommendations.

Objectives: Cardiology referral is common for patients admitted for non-cardiac diseases. Recommendations from cardiologists may involve complex and aggressive treatments that could be ignored or denied by other physicians. The purpose of this study was to compare the outcomes of patients who were given recommendations during cardiology referrals and to examine the clinical outcomes of patients who did not follow the recommendations.

Carotid stenosis management: a review for the internist.

Stroke is one of the most important causes of mortality and morbidity worldwide and, for a long time, was the leading cause of death in developed countries. Atherothrombotic carotid stenosis is one of the most important etiologies behind this event. If properly recognized and treated, lives can be saved, as well as long-term disabilities prevented.

A review of the recycling of non-metallic fractions of printed circuit boards.

There is a big waste generation nowadays due to the growing demand for innovation and the fact that more and more products have a reduced lifetime, increasing the volume of dumps and landfills. Currently, one of the segments of large volume is the technology waste, which reflects on the printed circuit boards (PCBs) that are the basis of the electronics industry. This type of waste disposal is difficult, given that recycling is complex and expensive, because of the diversity of existing materials and components, and their difficult separation process.

Perioperative cardiovascular evaluation: heads or tails?

When dealing with surgical patients, a perioperative evaluation is essential to anticipate complications and institute measures to reduce the risks. Several algorithms and exams have been used to identify postoperative cardiovascular events, which account for more than 50% of perioperative mortality. However, they are far from ideal.

Coronary plaque rupture in patients with myocardial infarction after noncardiac surgery: frequent and dangerous.

Purpose: The pathophysiology of acute coronary syndromes (ACS) after noncardiac surgery is not established yet. Thrombosis over a vulnerable plaque or decreased oxygen supply secondary to anemia or hypotension may be involved. The purpose of this study was to investigate the pathophysiology of ACS complicating noncardiac surgery.

Non-cardiac surgery in developing countries: epidemiological aspects and economical opportunities--the case of Brazil.

Background: Worldwide distribution of surgical interventions is unequal. Developed countries account for the majority of surgeries and information about non-cardiac operations in developing countries is scarce. The purpose of our study was to describe the epidemiological data of non-cardiac surgeries performed in Brazil in the last years.

Spondylodiscitis and infectious endocarditis: a round-trip to be considered.

The association between spondylodiscitis and endocarditis was first reported in 1965 by de Sèze et al. The most common clinical picture of this association is musculoskeletal symptoms preceding endocarditis diagnosis, but we report here a case of spondylodiscitis complicating endocarditis in its late course. A 70-year-old man, with an established diagnosis of mitral valve endocarditis caused by Streptococcus intermedius, early submitted to surgical treatment because of heart failure, who had an uneventful recovery up to the 12th day of antibiotic therapy when he presented intensive backache, with tenderness in the two lower lumbar vertebras.

Acute pericarditis with transient constriction: surgical impetus must be contained.

Constrictive pericarditis is typically a chronic and progressive condition characterised by debilitating chronic right heart failure and surgical pericardiectomy remains the treatment of choice. Although most cases of acute pericarditis are self-limiting, an uncommon but known complication is a transient form of constrictive pericarditis that shares the same clinical features with the chronic form but resolves without surgical intervention.We report a case of a 29-year-old man with acute idiopathic pericarditis complicated with overt signs of constriction with complete recovery after medical treatment.

Cardiovascular prevention in HIV patients: results from a successful intervention program.

Objectives: To analyze the effect of a prevention program on the estimated cardiovascular risk calculated by three risk scores.

Methods: We prospectively evaluated 87 HIV+patients with elevated cardiovascular risk estimation. Framingham (FRS), PROCAM and National Cholesterol Education Program (ATP-III) were applied.
