In the backdrop of the global obesity pandemic, recognized as a notable risk factor for coronavirus disease 2019 (COVID-19) complications, the study aims to explore clinical and epidemiological attributes of hospitalized COVID-19 patients throughout 2021 in Brazil. Focused on four distinct age cohorts, the investigation scrutinizes parameters such as intensive care unit (ICU) admission frequency, invasive mechanical ventilation (IMV) usage, and in-hospital mortality among individuals with and without obesity. Using a comprehensive cross-sectional study methodology, encompassing adult COVID-19 cases, data sourced from the Influenza Epidemiological Surveillance Information System comprises 329 206 hospitalized patients.

The restrictions on face-to-face care for exposure to biological material during the COVID-19 pandemic required alternatives to maintain outpatient assistance. This study evaluated the impact of telemedicine on care and outcome indicators of a reference service for exposure to biological material during the COVID-19 pandemic. This pre- and post-study compared the effectiveness of telemedicine in the Hospital Correia Picanço in Recife (Pernambuco, Brazil) before (August 2018 to January 2019 [P1]) and during the COVID-19 pandemic (August 2020 to January 2021 [P2]).

Objective: To describe accidents involving brown spider (genus Loxosceles) bites notified by the Pernambuco Poison Information and Care Center (CIATox-PE), Brazil, from January 2018 to December 2022.

Methods: This was a case series study of brown spider bites notified by the CIATox-PE.

Results: The study included 22 cases with median age of 35 years, the majority being female (13); the cases occurred in rural and urban areas (12 versus 10), at night (10); Petrolina was the municipality with the highest number of notifications (6); spider bites occurred mainly in the lower (11) and upper (9) limbs, almost exclusively inside households (21); specific serum therapy was not indicated for 8 cases because the time for its effectiveness had already elapsed.

Purpose: To assess the prophylaxis effect of pentoxifylline and tocopherol (PENTO) on the frequency and severity of medication-related osteonecrosis of the jaw (MRONJ) diagnosed at three months in patients with cancer submitted to tooth extractions during the treatment with bone-modifying agents.

Methods: This case series was conducted at the outpatient dental clinic of the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) between April 2021 and April 2022.

Introduction: To determine the incidence, morbidity, and mortality rate of laryngeal cancer in two decades and its epidemiological, clinical, and histological characteristics by sex in Brazil.

Methods: This ecological study used three reliable sources of secondary data: population- and hospital-based cancer registries and the national mortality database. All data available from 2000 to 2019 were considered.

The improvement of surgical techniques in kidney transplantation aims to reduce the incidence of post-transplant complications, contributing to the reduction of hospital stay, related costs, morbidity and mortality, in addition to improving the quality of life of patients. The choice of the best technique is influenced by several factors and the most common technique for urinary tract reconstruction in transplants is performed with implantation of the ureter of the graft in the caudal position, with the anastomosis performed in the bladder. However, the kidney pole can be inverted and the graft ureter anastomosis can be performed directly on the recipient's ureter, facilitating venous and ureteral anastomoses and reducing urological complications.

Regular physical activity prevents and treats cancer patients by assisting and improving the immune system. Co-stimulatory molecules that activate the immune system have been studied in cancer, such as immune checkpoint molecules of the CD40/CD40L pathway. This study aimed to characterize plasma levels of soluble CD40 (sCD40) and CD40 ligand (sCD40L) in older people with gastrointestinal tract (GIT) cancer and associate results with physical activity.

COVID-19 in children and adolescents has low frequency, severity, and fatality rate all over the world. A cross-sectional study was conducted to assess the epidemiological and clinical aspects of COVID-19 in patients younger than 20 years in Pernambuco (Brazil), with cases confirmed by reverse-transcriptase-PCR SARS-CoV-2 between 13 February and June 19, 2020, reported on information systems. Data regarding age (< 30 days, 1-11 months, 1-4 years, 5-9 years, 10-14 years, and 15-19 years), gender, color/race, symptoms, pregnancy or puerperium, comorbidities, hospitalization, and death were investigated.

Background: Lung cancer is the principal cause of cancer-related deaths worldwide; however, there has been controversy as to whether there is a difference in survival rate according to gender in Brazil. The aim of the present study, therefore, was to compare the epidemiologic and clinical profile and the overall survival of patients with lung cancer according to gender.

Patients And Methods: A retrospective cohort study was performed involving 1283 patients diagnosed with lung cancer between 2006 and 2014 at a single cancer center.

Background And Objectives: The prognosis of colorectal cancer (CRC) has improved in the last decades, however, a lower overall survival persists in the elderly. The understanding of immunity changes in the elderly with CRC will allow the emergence of new treatments with higher response rates. 4-1BB and CD40L, an immune checkpoint stimulator, play an important role in T-cell responses and platelets.

Article Synopsis
  • The study focuses on classifying elderly cancer patients using machine learning (ML) algorithms and comprehensive geriatric assessments (CGA) to gauge their risk of early death.
  • The research evaluated the ability of various ML models to predict mortality within six months of diagnosis, assessing a cohort of 608 patients through a combination of questionnaires related to mental health, physical activity, and overall health status.
  • Results indicated that specific subsets of CGA questionnaires could effectively predict early death, often outperforming models that used the full set of questionnaires.
