Dear Editor, Acute respiratory failure (ARF) is a leading cause of pediatric hospitalizations, and invasive mechanical ventilation (IMV) is an essential support in severe cases.() Data obtained through expiratory and inspiratory pause maneuvers on mechanical ventilators during spontaneous breathing in adult IMV patients have been shown to aid prevention of patient self-inflicted lung injury (P-SILI).(,) […]

Dear Editor, With this letter, we aim to supplement the data published by Colleti Junior et al.() Evaluating the global prevalence of validated delirium assessment tools and implementing delirium management protocols is essential.() Delirium often complicates the care of elderly patients in hospitals, rehabilitation centers, and long-term care facilities, necessitating effective strategies to mitigate its effect on patient outcomes and recovery.() […]

Dear Editor, The article titled “Factors underlying the high occupational risk of healthcare personnel for COVID-19 infection,”() published in this journal, contributes to the discussion on the occupational risk of SARS-CoV-2 contamination among health professionals and the relevance of the application of infection-prevention and control measures in routine care. […]

Dear Editor, We aimed to address a paper on the systematic system of ultrasonographic findings for the diagnosis of COVID-19 pulmonary symptoms.() The paper described the development of a scoring system to identify lung involvement based on ultrasonography results. Most of the 69 tests were conducted on girls aged 1–96 years. The findings revealed a link between higher COVID-RADS scores and ground-glass opacities on CT, with the majority falling into category 1 and 2. Half of the patients in the […]

Dear Editor, Pediatric acute respiratory distress syndrome is one of the main pediatric intensive care unit admission diagnoses.() The adjustment of positive end-expiratory pressure (PEEP) to improve lung compliance and oxygenation is a key treatment strategy.(,) However, there is a lack of evidence regarding the proper adjustment of PEEP during daily care.(,) […]

Dear Editor, In late 2021, two driven medical students from Faculdade Israelita Albert Einstein (FICSAE) in São Paulo, Brazil, initiated the “Kavanah Project.”() This initiative targets the improvement of healthcare access by conducting surgical missions in areas with long wait times for medical procedures, a prevalent issue in Brazil.(,) Diverging from conventional approaches, Kavanah, meaning “direction,” “intention,” or “purpose” in Hebrew, underscores a deliberate method of medical assistance, echoing deeper institutional principles of good deeds (Mitzvá), health (Refuá), education (Chinuch), […]

Dear Editor, An alarming number of pandemics are affecting the world’s population, including viral infections, overweight/obesity, and metabolic disorders. Genetic variants may be involved in underlying mechanisms of lipid metabolism and intrahepatic fat accumulation. The minor allele frequencies (MAFs) of variants in the microsomal triglyceride transfer protein (MTTP) gene, which unbalance the concentration of cholesterol, low-density lipoprotein and apolipoprotein B,(–) were investigated in 241 healthy Brazilians. […]

Dear Editor, Vieira et al. brought forward interesting observations in their study “ChatGPT: immutable insertion in health research and researchers’ lives.()” The article demonstrated how ChatGPT’s unchangeable information insertion can transform health research and the lives of researchers. In this sense, artificial intelligence is promising for improving researcher collaboration and streamlining the research process. The writers did an excellent job of highlighting ChatGPT’s advantages for healthcare and how it can further medical research. […]

Dear Editor, The World Health Organization has listed oxygen as an essential medicine.() Commonly prescribed for hospitalized pediatric and adult patients, there is a wide opportunity to improve its effectiveness by promoting the more rational, sustainable, and safe use of supplemental oxygen.(,) Guidelines and recommendations for oxygen use may help healthcare workers to adopt and achieve specific oxygen targets,() mitigating hyperoxemia, and hypoxemia.(,) Staying within safe targets, however, can be challenging, and is also quite time-consuming and labor-intensive, as it […]

Dear Editor, Scientific advancements driven by an increased understanding of big data, patient preferences, and high-quality research have revealed the need for rapid responses.() In this scenario, the use of artificial intelligence (AI), which enables the possibility of obtaining full texts, which mimic human language patterns, from a short sentence, with the adoption of AI tools such as Chat generative Pre-trained Transformer-ChatGPT (Open AI, San Francisco, CA, USA), is attractive.() A growing number of researchers are evaluating the potential of […]
