Atopic dermatitis (AD) is a chronic inflammatory skin disease whose main symptoms are redness, swelling, and itchy rashes. It is more common in people with a genetic predisposition. The manifestation of symptoms depends on interactions among the immune system, environmental factors, and gut microbiota. Many pieces of this complex jigsaw puzzle are still undiscovered, but recent research has identified relevant factors. For example, alterations in gut microbiota composition can contribute to [...]

Diagnosing autism spectrum disorder (ASD) is still a daunting challenge because of the degree of complexity involved, requiring highly specialized professionals. Autism is a multifactorial neurodevelopment disorder with widely varying symptoms. In the United States, about 1 in 36 children have been diagnosed with ASD, according to the Centers for Disease Control and Prevention (CDC), and yet there are no biochemical markers to identify it with precision. A quantitative diagnostic method is [...]

Since the start of the COVID-19 pandemic, a class of corticosteroids called glucocorticoids (GCs) have become established as one of the main treatment options, especially for severe cases, thanks to their anti-inflammatory and immunosuppressant action. Brazilian researchers recently discovered new ways in which these drugs influence the organism’s inflammatory response during an infection: they raise levels of endocannabinoids (eCBs), molecules produced by the organism itself and that [...]

Strength training practiced with moderate to vigorous intensity two or three times a week is an effective way to mitigate arterial hypertension (high blood pressure), according to a Brazilian study described in an article published in the journal Scientific Reports. The mechanisms behind the lowering of blood pressure by aerobic exercise are well studied, but little research has been done on the effects of strength exercise on hypertension along similar lines to this review [...]

The link between symptoms of COVID-19 and physical inactivity is increasingly evident. An article recently published in the journal Scientific Reports by researchers at the University of São Paulo (USP) in Brazil describes a study in which COVID-19 survivors with at least one persistent symptom of the disease were 57% more likely to be sedentary, and the presence of five or more post-acute sequelae of infection by SARS-CoV-2 increased the odds of physical inactivity [...]

A research involving 800 youngsters confirmed that the inclusion of sugar of their weight loss plan and early interruption of breastfeeding are the primary elements that contribute to the looks of dental caries by the age of two years. The research was printed within the journal ‘Neighborhood Dentistry and Oral Epidemiology’. The World Well being Group (WHO) recommends unique breastfeeding for the primary six months of life, adopted by continued breastfeeding together with [...]

A study involving 800 children shows inclusion of sugar in their diet and early interruption of breastfeeding to be the main factors that contribute to the appearance of dental caries by age 2. An article reporting the results is published in the journal Community Dentistry and Oral Epidemiology. The World Health Organization (WHO) recommends exclusive breastfeeding for the first six months of life, followed by solid food together with continued on-demand breastfeeding up to 2 [...]

 One of the most dreaded effects of the bite of the brown recluse spider (Loxosceles spp) is the appearance of a… One of the most dreaded effects of the bite of the brown recluse spider (Loxosceles spp) is the appearance of a necrotic skin lesion, but a clinical study by Brazilian researchers recently reported in PLOS Neglected Tropical Diseases shows that the problem can be solved by administering antivenom, especially if this is done within 48 hours of [...]

Proven to protect against a wide array of diseases, exercise may be the most powerful anti-aging intervention known to science. However, while physical activity can improve health during aging, its beneficial effects inevitably decline. The cellular mechanisms underlying the relationship among exercise, fitness and aging remain poorly understood. In a paper published in the Proceedings of the National Academy of Sciences, researchers at Joslin Diabetes Center investigated the role of [...]
