Clinical Features, Genetic Findings, and Risk Stratification in Arrhythmogenic Right Ventricular Cardiomyopathy: Data From a Brazilian Cohort.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC), a rare inherited disease, causes ventricular tachycardia, sudden cardiac death, and heart failure (HF). We investigated ARVC clinical features, genetic findings, natural history, and the occurrence of life-threatening arrhythmic events (LTAEs), HF death, or heart transplantation (HF-death/HTx) to identify risk factors.

Methods: The clinical course of 111 consecutive patients with definite ARVC, predictors of LTAE, HF-death/HTx, and combined events were analyzed in the entire cohort and in a subgroup of 40 patients without sustained ventricular arrhythmia before diagnosis.

Direct healthcare cost of hospital admissions for chronic non-communicable diseases sensitive to primary care in the elderly.

Aging has imposed changes in the epidemiological profile and an increase in the prevalence of chronic non-communicable diseases (CNCDs). The aim was to estimate the direct cost related to hospital admissions of elderly people affected by CNCDs (hypertension, heart failure and diabetes mellitus) sensitive to primary care, in a medium-sized hospital, in the period 2015-2019. Secondly, we investigated whether clinical and demographic factors explain the costs and length of stay.

Clinical outcomes and lung mechanics characteristics between COVID-19 and non-COVID-19-associated acute respiratory distress syndrome: a propensity score analysis of two major randomized trials.

Objective: To compare the lung mechanics and outcomes between COVID-19-associated acute respiratory distress syndrome and non-COVID-19-associated acute respiratory distress syndrome.

Methods: We combined data from two randomized trials in acute respiratory distress syndrome, one including only COVID-19 patients and the other including only patients without COVID-19, to determine whether COVID-19-associated acute respiratory distress syndrome is associated with higher 28-day mortality than non-COVID-19 acute respiratory distress syndrome and to examine the differences in lung mechanics between these two types of acute respiratory distress syndrome.

Results: A total of 299 patients with COVID-19-associated acute respiratory distress syndrome and 1,010 patients with non-COVID-19-associated acute respiratory distress syndrome were included in the main analysis.

Ketamine use in critically ill patients: a narrative review.

Ketamine is unique among anesthetics and analgesics. The drug is a rapid-acting general anesthetic that produces an anesthetic state characterized by profound analgesia, preserved pharyngeal-laryngeal reflexes, normal or slightly enhanced skeletal muscle tone, cardiovascular and respiratory stimulation, and occasionally a transient and minimal respiratory depression. Research has demonstrated the efficacy of its use on anesthesia, pain, palliative care, and intensive care.

Results: in leaders' perception, there was no evidence of significant associations between burnout and authentic leadership scales.

DYT-TUBB4A (DYT4 Dystonia): Clinical Anthology of 11 Cases and Systematized Review.

Background: DYT-TUBB4A, formerly known as DYT4, has not been comprehensively described as only one large family and three individual cases have been published. We have recently described an in depth genetic and protein structural analysis of eleven additional cases from four families with four new pathogenic variants. We aim to report on the phenomenology of these cases suffering from DYT-TUBB4A and to perform a comprehensive review of the clinical presentation and treatment responses of all DYT-TUBB4A cases reported in the literature.

Knowledge of gynecologists in the public health system care of women victims of violence.

Objective: This study aimed to evaluate the knowledge of the obstetricians and gynecologists in the care of women victims of violence in the public health system and the existence of institutional mechanisms to support them.

Methods: A cross-sectional and observational study was conducted with an electronic questionnaire by physicians who provided care in the obstetrics and gynecology emergency unit of the public health system. This study aimed to identify the care for victims of violence who received the institutional mechanisms of support, the difficulties encountered in determining the appropriate care, and estimates of the prevalence of violence against women.

Chronic Stroke Sensorimotor Impairment Is Related to Smaller Hippocampal Volumes: An ENIGMA Analysis.

Background Persistent sensorimotor impairments after stroke can negatively impact quality of life. The hippocampus is vulnerable to poststroke secondary degeneration and is involved in sensorimotor behavior but has not been widely studied within the context of poststroke upper-limb sensorimotor impairment. We investigated associations between non-lesioned hippocampal volume and upper limb sensorimotor impairment in people with chronic stroke, hypothesizing that smaller ipsilesional hippocampal volumes would be associated with greater sensorimotor impairment.

Scaling laws and the left main coronary artery bifurcation. A combination of geometric and simulation analyses.

The geometry of coronary arteries is believed to play the role as an atherosclerotic risk factor on its own. The full characterization of the normal coronary network has been reported in the literature. Reports on the integration of geometry and functional data for normal coronary vessels started to proliferate more recently.

Assessing the Accuracy of Estimated Lipoprotein(a) Cholesterol and Lipoprotein(a)-Free Low-Density Lipoprotein Cholesterol.

Background Accurate measurement of the cholesterol within lipoprotein(a) (Lp[a]-C) and its contribution to low-density lipoprotein cholesterol (LDL-C) has important implications for risk assessment, diagnosis, and treatment of atherosclerotic cardiovascular disease, as well as in familial hypercholesterolemia. A method for estimating Lp(a)-C from particle number using fixed conversion factors has been proposed (Lp[a]-C from particle number divided by 2.4 for Lp(a) mass, multiplied by 30% for Lp[a]-C).

Cervical arthroplasty in a professional kick-boxing fighter, 7 years follow-up.

Spinal surgery in professional athletes is a topic of much discussion. Anterior cervical discectomy and fusion (ACDF) is the standard procedure used by surgeons, and other techniques used to treat athletes includes foraminotomies, laminoplasties and total disc replacement. Total disc replacement is an unusual technique used to treat athletes in general and is becoming a more important issue in full contact sports.
