A strain of Klebsiella pneumoniae, previously identified in the United States, is a common cause of hospital infections and is resistant to all available antibiotics. In 2022, a strain of Klebsiella pneumoniae isolated from an 86-year-old woman with a urinary infection in Brazil's Northeast region was found to be resistant to all available antibiotics. The patient passed away 24 hours after being admitted to the hospital (1 ✔ ✔Trusted Source Global epidemiological trend of [...]

Watch out! When blood sugar soars and diabetic ketoacidosis (DKA) strikes, thrombosis can follow. High blood sugar (hyperglycemia), a symptom of diabetes, can lead to thrombosis, reveals a new study conducted at the Center for Research on Redox Processes in Biomedicine (Redoxoma). The findings, reported in an article published in the Journal of Thrombosis and Haemostasis, can contribute to the development of strategies to prevent cardiovascular dysfunction in diabetics (1 ✔ ✔Trusted [...]

People consuming fewer industrialized products, like protein supplements and textured soy protein, were more likely to have inadequate protein and amino acid intake compared to those eating unprocessed and minimally processed foods. In a study published in JAMA Network Open, researchers from the University of São Paulo’s Medical School (FM-USP) examined 774 men and women following a vegan diet in Brazil (1✔). Coined by researchers at the same [...]

Levodopa, a medication that affects dopamine levels, has been shown to improve sleep quality in a study involving twenty-two individuals with Parkinson's disease (PD). After beginning the medication, the average number of nighttime awakenings for the patients decreased by 25%, and the average duration of time spent awake at night decreased by 30%. ‘Patients with #Parkinson's disease experience #REM sleep behavior disorder, frequent nighttime awakenings, and daytime drowsiness. [...]

Measuring blood levels of homocysteine, an amino acid, can predict a person's risk of developing obstructive sleep apnea. This test also aids clinicians in assessing whether patients with mild or moderate forms of the disorder may progress to its severe form (1✔). “We don’t yet know whether apnea causes the rise in blood levels of homocysteine or the rise in levels of this amino acid causes severe apnea. Our hypothesis is that it’s a two-way [...]

WhatsApp can be an extremely effective tool for alleviating loneliness and depression among older adults, as demonstrated by a study conducted in Guarulhos, the second-largest city in São Paulo state, Brazil (1 ✔). The study is detailed in an article published in the journal Nature Medicine. Marcia Scazufca, a scientific researcher at Hospital das Clínicas (HC) and a professor at the University of São Paulo’s Medical School (FM-USP), is a co-corresponding [...]

University of São Paulo research suggests the virus can remain in sperm for up to 110 days after infection, reducing sperm quality. They have discovered that the SARS-CoV-2 virus, responsible for COVID-19, can linger in sperm for extended periods. Their findings, published in the journal Andrology, indicate the virus can persist up to 90 days after hospital discharge and 110 days after initial infection. This extended presence coincides with a decrease in semen quality (1 [...]

A groundbreaking study mapped heatwave-related mortality worldwide over a span of three decades, from 1990 to 2019. The findings reveal that over 153,000 additional deaths occurred per warm season due to heatwaves, with Asia bearing the brunt of nearly half of these fatalities (1✔).In comparison to 1850–1990, the global surface temperature has increased by 1.14℃ in 2013–2022 and is expected to increase by another 0.41-3.41℃ by 2081–2100. With the [...]

Researchers from the University of Western São Paulo (UNOESTE) and São Paulo State University (UNESP) in Brazil have developed a nanoemulsion containing curcumin, which demonstrated the ability to modulate the gut microbiota of mice suffering from intestinal inflammation (1✔). This formulation exhibits promise in alleviating inflammation and promoting gut health as per a study that was supported by FAPESP (projects 22/12823-0, 20/15185-0, and 17/03879-4), and is [...]
