Earth’s gravity has shaped human beings over thousands of years. It was clear from the first extraterrestrial spaceflight entering orbit that microgravity, due to an object being in free fall, immediately affects human body functions because of the increase, reduction, or absence of gravity.

Brucellosis is a disease caused by bacteria and can be transmitted to humans through direct or indirect contact with farm animals or by contact with companion animals. The milk ring test (MRT) is one of the ways used to identify the disease at the dairy herd level. Analyses indicate that the MRT can be used on milk samples with a preservative (Bronopol®).

Honduran women residing in the USA, employed in domestic occupations, typically tend to be younger, have access to bank accounts, and maintain lower savings compared to individuals in other occupations. Additionally, they often earn a significantly lower income. These findings underscore the challenges faced by this particular group and emphasize the importance of enhancing their working conditions and rights. Read More →

Enhancing pandemic predictions by measuring daily contacts

Jaboatão City Hall employees distribute new clothes, masks and hygiene kits to homeless people.

The first global SARS-CoV-2 pandemic challenged existing measurement methods for respiratory diseases. While digital technologies were initially touted for real-time monitoring, the key has proven to be careful measurement of daily face-to-face contacts, which is essential for refining mathematical models to assess infection, recovery, and mortality.

Pregnant women treated with continuous subcutaneous insulin infusion have better glycemic control

Photograph of a pregnant woman with hands on her belly.

In a comparison of maternal-fetal outcomes among T1D patients treated with continuous subcutaneous insulin infusion (CSII) or multiple daily injections during pregnancy, a higher frequency of cesarean and a lower occurrence of congenital malformations group were observed in the CSII. Adjusted results might indicate that these are influenced by glycemic control. Read More →

Analysis reveals reduction of pesticides in CEASA/SP strawberries

Stratifying hypoechogenicity into 3 degrees improves ultrasound thyroid nodule risk stratification

Collage of four ultrasound images. Arrows point to the hypoechoic nodules in different degrees.

The analysis of different degrees of hypoechogenicity in thyroid nodules shows that the classification into three grades (mild, moderate, and severe) allows for better differentiation between benign and malignant nodules. The method can avoid unnecessary invasive procedures, in addition to improving efficiency and accuracy in the evaluation of thyroid nodules. Read More →
