Although 30 to 50% of hospitalized patients in a critical care unit are under sedation, there is sparse data on the impact of sedation on morbidity and case-fatality rates in Brazil. Sedation is associated with higher risks of infection and death rate among patients. However, it is difficult to assess the clinical impact of sedation. To evaluate the impact of sedation on the incidence of nosocomial infection and all-cause deaths at a critical care unit. Prospective study. Tertiary-care teaching hospital. After the exclusion of patients hospitalized for less than 24 hours, 307 patients were assigned to two groups, considering their states of sedation. After confirmation of heterogeneity in relation to the Acute Physiology and Chronic Health Evaluation (APACHE II) prognostic system, 97 sedated and 97 non-sedated patients were matched in relation to this severity index. Impact of sedation on deep venous thrombosis, incidence of decubital eschars, presence of infection, mortality and length of hospital stay. There was no difference in the incidence of deep venous thrombosis between the sedated and non-sedated groups, while the frequency of decubital eschars was significantly higher among sedated patients (p = 0.03). Infection was d...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.


Incretins are metabolic hormones that stimulate a decrease in glucose levels in the blood and they have been implicated in glycemic regulation in the remission phase of type 1 diabetes. Here is the latest research.

The circadian clock plays an important role in regulating transcriptional dynamics through changes in chromatin folding and remodelling. Discover the latest research on Chromatin Regulation and Circadian Clocks here.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.
