Postorotracheal intubation dysphagia in patients with COVID-19: A retrospective study.

Background: The cause of oropharyngeal dysphagia in patients with coronavirus disease (COVID-19) can be multifactorial and may underly limitations in swallowing rehabilitation.

Objective: Analyze the factors related to dysphagia in patients with COVID-19 immediately after orotracheal extubation and the factors that influence swallowing rehabilitation.

Design And Setting: A retrospective study.

Critical assessment of resource waste in staging and follow-up of breast cancer.

Background: Breast cancer is a public health problem with both high incidence and cure rates. After treatment, patients are monitored for long periods of time due to the risk of recurrence. Thus, staging and follow-up strategies should consider not only the best results for the patient but also its costs for the public health system.

Assessment of the median ages at sexual maturation stages of Brazilian schoolchildren according to overweight status and type of school over a 5-year period: 2007-2012/2013.

Objectives: A secular trend of earlier puberty has been observed in girls, and, although more uncertain in boys, is associated with an increasing trend in the prevalence of overweight and obesity. We aimed to compare the median ages of sexual maturation stages in schoolchildren from a city in southern Brazil over a 5-year period, according to weight status and type of school.

Methods: Two cross-sectional studies were performed in 2007 and 2012/2013, including 2215 and 1614 schoolchildren, respectively.

Hospital Admissions Associated With Noncommunicable Diseases During the COVID-19 Outbreak in Brazil.

This cross-sectional study uses data from the Brazilian Unified Health System to compare the number of hospital admissions for treatment of noncommunicable diseases from January to June 2020 with that during the corresponding period in each of the previous 3 years in São Paulo, Brazil.

Waiting Time between Breast Cancer Diagnosis and Treatment in Brazilian Women: An Analysis of Cases from 1998 to 2012.

Brazilian law requires that treatment for breast cancer begin within 60 days of diagnosis. This waiting time is an indicator of accessibility to health services. The aim of this study was to analyze which factors are associated with waiting times between diagnosis and treatment of breast cancer in women in Brazil between 1998 and 2012.

Prone positioning to improve oxygenation and relieve respiratory symptoms in awake, spontaneously breathing non-intubated patients with COVID-19 pneumonia.

Emergency departments are facing an unprecedented challenge in dealing with patients who have coronavirus disease 2019 (COVID-19). The massive number of cases evolving to respiratory failure are leading to a rapid depletion of medical resources such as respiratory support equipment, which is more critical in low- and middle-income countries. In this context, any therapeutic and oxygenation support strategy that conserves medical resources should be welcomed.

Evaluation of the systemic and therapeutic repercussions caused by drug interactions in oncology patients.

Introduction: Drug interaction is an important cause of global morbidity. It is of particular importance in cancer patients since they are often in use of polypharmacy, related to interactions between the drugs and the chemotherapeutics used.

Objective: To evaluate the drug interaction between chemotherapy and other drugs in cancer patients.

Uremic neuropathy: an overview of the current literature.

Introduction: Peripheral neuropathy is a disorder that affects the cell body, axon or myelin of motor or peripheral sensory neurons and occurs in 60-100% of patients who are submitted to dialysis due to chronic kidney disease. Uremic neuropathy (UN) is attributed to the accumulation of organic waste, evident in patients with reduced glomerular filtration rate.

Objectives: This review aims to make clinical characteristics of uremic neuropathy evident enabling early diagnosis and treatment.

Regional differences in the temporal evolution of stroke: a population-based study of Brazil according to sex in individuals aged 15-49 years between 1997 and 2012.

Objective: The present study analyzed the temporal trend of stroke mortality according to sex in individuals aged 15-49 years in the different regions of Brazil between 1997 and 2012.

Results: There was progressive reduction in mortality rate due to stroke in Brazil. The reduction trend was the same for both sexes, although mortality remained slightly higher among men.

Purified Dry Paullinia cupana (PC-18) Extract for Chemotherapy-Induced Fatigue: Results of Two Double-Blind Randomized Clinical Trials.

Fatigue is frequent among oncologic patients. Unpurified Paullinia cupana dry extract showed encouraging results for chemotherapy-induced fatigue in our previous studies. We report two randomized, double-blind studies with a standardized dry purified Paullinia cupana extract named PC-18.

Medical Student Oncology Congress: Designed and Implemented by Brazilian Medical Students.

Oncology is an essential field of medicine; however, its teaching is occasionally underemphasized and uncoordinated during medical school. An alternative method of providing additional oncological information to medical students is through extracurricular activities, such as congresses and medical student associations. The aim of this paper is to describe a Medical Student Oncology Congress entirely designed and organized by medical students.
