The skin cannot be considered as just a barrier that protects against physical, chemical, and biological damage; it is a complex and dynamic ecosystem that varies across lifespans. Interest in the relationship between physical activity and skin microbiota has grown significantly in recent years. The skin microbiota has a crucial role in skin functions and physiology, and an imbalance, known as dysbiosis, is correlated with several diseases, such as inflammatory bowel disease (IBD), infectious disease, obesity, allergic disorders, and type 1 diabetes mellitus.

It has been well established that the human gut microbiota plays a pivotal role in humans' health, since it is involved in nutrients' uptake, vitamins' synthesis, energy harvest, inflammatory modulation, and host immune responses. Moreover, gut microbiota alterations have been associated to an increasing number of diseases and its composition can be affected by several factors, including physical exercise. In particular, it has been reported that intense physical activity can induce metabolic changes which translate in alterations of specific biomarkers that can lead to the onset of infections, inflammation and hepatic or kidney disorders.

Physical activity highly impacts the neuroendocrine system and hormonal secretion. Numerous variables, both those related to the individual, including genetics, age, sex, biological rhythms, nutritional status, level of training, intake of drugs or supplements, and previous or current pathologies, and those related to the physical activity in terms of type, intensity, and duration of exercise, or environmental conditions can shape the hormonal response to physical exercise. The aim of this review is to provide an overview of the effects of physical exercise on hormonal levels in the human body, focusing on changes in concentrations of hormones such as cortisol, testosterone, and insulin in response to different types and intensities of physical activity.

The hemostatic system is characterized by a delicate balance between pro- and anticoagulant forces, and the smallest alteration can cause serious events such as hemorrhages or thrombosis. Although exercise has been shown to play a protective role in athletes, several factors may increase the risk of developing venous thromboembolism (VTE), including hemoconcentration induced by exertion, immobilization following sports injuries, frequent long-distance flights, dehydration, and the use of oral contraceptives in female athletes. Biomarkers such as D-dimer, Factor VIII, thrombin generation, inflammatory cytokines, and leukocyte count are involved in the diagnosis of deep vein thrombosis (DVT), although their interpretation is complex and may indicate the presence of other conditions such as infections, inflammation, and heart disease.

Autism spectrum disorder is a neurodevelopmental disorder characterized by social interactions and communication skills impairments that include intellectual disabilities, communication delays and self-injurious behaviors; often are present systemic comorbidities such as gastrointestinal disorders, obesity and cardiovascular disease. Moreover, in recent years has emerged a link between alterations in the intestinal microbiota and neurobehavioral symptoms in children with autism spectrum disorder. Recently, physical activity and exercise interventions are known to be beneficial for improving communication and social interaction and the composition of microbiota.

Deep brain stimulation (DBS) is a medical treatment that aims to obtain therapeutic effects by applying chronic electrical impulses in specific brain structures and neurological circuits. Over the years, DBS has been studied for the treatment of many psychiatric disorders. Scientific research on the use of DBS in people with autism has focused this interest mainly on treatment-resistant obsessive-compulsive disorder, drug-resistant epilepsy, self-injurious behaviors (SIB), and aggressive behaviors toward the self.

Pregnancy is characterized by significant immunological changes and a cytokine profile, as well as vitamin deficiencies that can cause problems for the correct development of a fetus. Defensins are small antimicrobial peptides that are part of the innate immune system and are involved in several biological activities. Following that, this study aims to compare the levels of various cytokines and to investigate the role of defensins between pregnant women with confirmed COVID-19 infection and pregnant women without any defined risk factor.

Animals require a certain amount of habitat to persist and thrive, and habitat loss is one of the most critical drivers of global biodiversity decline. While habitat requirements have been predicted by relationships between species traits and home-range size, little is known about constraints imposed by environmental conditions and human impacts on a global scale. Our meta-analysis of 395 vertebrate species shows that global climate gradients in temperature and precipitation exert indirect effects via primary productivity, generally reducing space requirements.

Article Synopsis
  • The gut microbiota consists of microorganisms in the gastrointestinal tract that help maintain bodily functions and influence growth and digestion.
  • Recent studies indicate a connection between the gut microbiota and the brain, known as the gut-brain-microbiota axis, which affects the Central Nervous System and can impact mental health, including disorders like Bipolar Disorder (BD).
  • The paper explores how changes in gut microbiota composition may relate to BD symptoms and treatment, suggesting that managing gut health could be a promising strategy for improving outcomes in BD patients.

Insects are the most ubiquitous and diverse group of eukaryotic organisms on Earth, forming a crucial link in terrestrial and freshwater food webs. They have recently become the subject of headlines because of observations of dramatic declines in some places. Although there are hundreds of long-term insect monitoring programs, a global database for long-term data on insect assemblages has so far remained unavailable.
