Longitudinal analysis of hospital morbidity and mortality due to skin cancer from 2012 to 2022: comparison with demographic and geographic factors in Brazilian states.

Background: Skin cancer is the most common neoplasm among Brazilians, accounting for 31.3% of all cancer cases in the country.

Objectives: To analyze the longitudinal morbimortality of skin cancer and compare it with the latitude and the prevalence of white skin color in each federative unit of the country.

Acute coronary syndrome in a hospital in southern Brazil: peak of hospitalizations on Mondays and severe cases on weekends and at night.

Introduction: Ischemic heart disease is the leading cause of death in Brazil and worldwide. The term acute coronary syndrome (ACS) generically represents the acute myocardial ischemic events. These events are clinically divided into three types: acute myocardial infarction (AMI) with ST-segment elevation, AMI without ST-segment elevation, and unstable angina.

Need for oxygen therapy and ventilatory support in premature infants in a hospital in Southern Brazil.

Background: Prematurity in newborns is a condition that is associated with worse hospital outcomes when compared to birth to term. A preterm infant (PI) is classified when gestational age (GA) < 37 wk.

Aim: To analyze prognostic indicators related to the use of oxygen therapy, non-invasive ventilation (continuous positive airway pressure) and mechanical ventilation (MV) in PI.

Level of Physical Activity Knowledge of Medical Students in a Brazilian University.

Background: Physical inactivity is a major global public health problem, with a large impact on morbidity and mortality. For this reason, knowledge and advice on physical activity (PA) should be common to all health professionals. In this context, the role of physicians stands out, because they act in the first contact and have a high potential in addressing this issue and its impact on health promotion, prevention, and treatment in chronic diseases.

Epidemiological profile of chest trauma and predictive factors for length of hospital stay in a hospital in Southern Brazil.

Introduction: Thoracic trauma is one of the most common types, corresponding to 10% of the traumas admitted in emergency services.

Objective: To analyse epidemiologic aspects of patients diagnosed with chest trauma in a hospital at the south of Brazil and its predictive factor for prolonged length of stay.

Methods: We conducted a retrospective cohort involving patients who were victims of chest trauma.

Effect of seasonality in hospitalizations and deaths from acute myocardial infarction in southern Brazil from 2009 to 2018.

Introduction: Acute myocardial infarction (AMI) is one of the main causes of morbidity and mortality in Brazil and worldwide. Seasonality and climate change seem to be associated with hospitalization for AMI.

Objective: to analyze the effect that seasonality and temperature have on the number of hospitalizations and deaths due to AMI, stratified by gender and age group, from 2009 to 2018 in a region of southern Brazil.

Percutaneous coronary intervention procedures performed at a hospital in Southern Brazil.

Background: Despite the advantages of percutaneous coronary intervention (PCI) compared to fibrinolytic therapy, it holds some potential risks such as contrast related reactions and technical problems. In addition, recent studies have shown disparities in which access is more exposed to radiation.

Objectives: To analyze the clinical profile, differences between radial and femoral approach and complications presented in patients who underwent PCI performed in a hospital in the south of Brazil.

Comparison of the ankle-brachial index with parameters of stiffness and peripheral arterial resistance assessed by photoplethysmography in elderly patients.

Background: The ankle-brachial index (ABI) uses the ratio between systolic blood pressures at the ankle and the arm to diagnose peripheral arterial disease (PAD) noninvasively. Photoplethysmography (PPG) measures and records changes to the blood volume in the human body using optical techniques.

Objectives: The objective of this study was to compare ABI with arterial stiffness and peripheral resistance parameters assessed using PPG in elderly patients and to propose a model for prediction of ABI.

Use of photoplethysmography to predict mortality in intensive care units.

Purpose: The aim of this study was to evaluate and compare the capacity to predict hemodynamic variables obtained with photoplethysmography (PPG) and Acute Physiology and Chronic Health Evaluation (APACHE II) in patients hospitalized in the intensive care unit (ICU).

Materials And Methods: A prospective cohort study was conducted in the adult ICU of Hospital Nossa Senhora da Conceição, located in Tubarão, Santa Catarina, Brazil. The data collected included the diagnosis for hospitalization, age, gender, clinical or surgical profile, PPG pulse curve signal, and APACHE II score in the first 24 hours.

Association between the Alvarado score and surgical and histopathological findings in acute appendicitis.

Objective: to compare the results of the Alvarado score with the surgical findings and the results of the histopathological examination of the appendix of patients operated on for acute appendicitis.

Methods: we conducted an observational study with a cross-sectional design of 101 patients aged 14 years and over undergoing emergency appendectomy. The evaluation comprised the Alvarado score, gender, age, ethnicity and time of evolution.

Respiratory mechanics, ventilator-associated pneumonia and outcomes in intensive care unit.

Aim: To evaluate the predictive capability of respiratory mechanics for the development of ventilator-associated pneumonia (VAP) and mortality in the intensive care unit (ICU) of a hospital in southern Brazil.

Methods: A cohort study was conducted between, involving a sample of 120 individuals. Static measurements of compliance and resistance of the respiratory system in pressure-controlled ventilation (PCV) and volume-controlled ventilation (VCV) modes in the 1 and 5 days of hospitalization were performed to monitor respiratory mechanics.

Factors associated with mortality among elderly people hospitalized due to femoral fractures.

Objective: To analyze factors associated with mortality among elderly people hospitalized in a single-center regional hospital due to femoral fractures.

Methods: This was a retrospective cohort study. Patients aged 60 years or over who were hospitalized with a diagnosis of femoral fracture (ICD S72) between 2008 and 2013 were selected through the electronic medical records.
