Summary: Caffeine is present in coffee and many other beverages and is the most widely used central nervous system stimulant. Coffee drinking or caffeine supplementation may have a role in preventing cardiometabolic and endocrine disease, neuroinflammation, cancer, and even all-cause mortality. Other aspects are either less known or controversial, including the effects on the brain-gut axis, neurodevelopment, behavior, pain, muscle-skeletal health, skin or sexual function. Studies focusing on special populations (neonates, children, adolescents, athletes, elderly, pregnant and nonpregnant women), or interactions with other drugs and foods, are relatively scarce but of obvious interest. Other compounds present in coffee and other caffeinated food stuffs may affect caffeine´s physiological effects with a tremendous impact on health. This Special Issue, which contains twenty-one manuscripts, has focused on some of these varied topics, providing further evidence of the multiple health benefits that coffee/caffeine intake may exert in humans, at least in specific populations (with a particular genetic profile or suffering from specific diseases). However, the specific effects in the different organs and systems, as well as the mechanisms involved are not yet clear. Furthermore, within the current context aiming to sustainable development, the coffee plant Coffee sp. and its so-far relatively neglected by-products are expected to become soon a source of ingredients for new functional foods whose properties will need to be precisely determined. We hope the readers of this Special Issue will find inspiration for new studies on the topic.

Summary: Clinical psychology based on gender medicine is a core topic of this Special Issue. In general, consideration of women's mental health is limited; however, it is important to consider subjective wellbeing factors connected with cultural, environmental, epigenetic and personality aspects. Many factors, such as the roles assigned to women nowadays in social and work contexts, can act as predisposing conditions in the etiology of the psychopathological frame, particularly affective disorders. Furthermore, in the developmental life of a woman, important risk factors can be highlighted, such as the vulnerability to psychological distress in women and couples. In particular, the topic addresses the individual maternal requirements for successful transition to healthy motherhood and innovative programs based on gender medicine in the life cycle considering student and elderly experiences. The connection of psychological vulnerability to the environment and repercussions for relationships have been studied in connection with the COVID-19 lockdown, induced changes in women's psychological distress and research regarding sexual arousal, self-image and mental wellbeing. Psychological and emotional forms of violence in couples, such as IPV, is another point highlighting new trend of assessments (i.e., Intimate Partner Violence EAPA-P) and ad hoc treatment in emotional regulation and resilience. Psychological support for women is central to the prevention of psychopathology, especially in relation to subthreshold traits; finally, the topic offers an overview of ad hoc treatments in clinical contexts.

Summary: The majority of newborns do not need medical interventions to manage the neonatal transition after birth. However, every year millions of newborns worldwide require respiratory support immediately after birth, and another considerable number of newborns additionally require extensive resuscitation including chest compressions and drug administration. Despite a significant increase in knowledge and development of enhanced therapy strategies over the past few years, morbidity and mortality caused by failures in neonatal transition remain an important health issue. The purpose of this reprint is to support or introduce novel concepts and add information in the area of the "Stabilization and Resuscitation of Newborns", aiming to improve neonatal care and, as the major objective, to enhance neuro-developmental outcomes.

Summary: Newborn Screening for Sickle Cell Disease and other Haemoglobinopathies is a Special Issue of the International Journal of Neonatal Screening. Sickle cell disease is one of the most common inherited blood disorders, with a huge impact on health care systems due to high morbidity and high mortality associated with the undiagnosed disease. Newborn screening helps to make the diagnosis early and to prevent fatal complications and diagnostic odysseys. This book gives an overview of diagnostic standards in newborn screening for sickle cell disease and examples of existing newborn screening programs.

Summary: Bacterial resistance to known and currently used antibiotics represents a growing issue worldwide. It poses a major problem in the treatment of infectious diseases in general and hospital-acquired infections in particular. This is in part due to the overuse and misuse of antibiotics in past decades, which led to the selection of highly resistant bacteria and even so-called superbugs - multidrug-resistant (MDR) bacteria. Nosocomial infections, particularly, are often caused by MDR bacterial pathogens and the treatment of such infections is very complicated and extensive, often leading to various side effects, including adverse effects on the natural human microbiome. At the same time, the development of novel antibiotics is lagging with very few new ones in the pipeline. Finding viable alternatives to treat such infections may help to overcome these therapeutic issues. This publication brings novel developments in the field of bacterial resistance, mainly in the hospital settings, adequate antibiotic therapy, and identification of compounds useful to battle this growing issue.

Summary: Creatine plays a critical role in cellular metabolism, primarily by binding with phosphate to form phosphocreatine (PCr) as well as shuttling high-energy phosphate compounds in and out of the mitochondria for metabolism. Increasing the dietary availability of creatine increases the tissue and cellular availability of PCr, and thereby enhances the ability to maintain high-energy states during intense exercise. For this reason, creatine monohydrate has been extensively studied as an ergogenic aid for exercise, training, and sport. Limitations in the ability to synthesize creatine and transport and/or store dietary creatine can impair metabolism and is a contributor to several disease states. Additionally, creatine provides an important source of energy during metabolically stressed states, particularly when oxygen availability is limited. Thus, researchers have assessed the role of creatine supplementation on health throughout the lifespan, as well as whether creatine availability may improve disease management and/or therapeutic outcomes. This book provides a comprehensive overview of scientific and medical evidence related to creatine's role in metabolism, health throughout the lifespan, and our current understanding of how creatine can promote brain, heart, vascular and immune health; reduce the severity of musculoskeletal and brain injury; and may provide therapeutic benefits in glucose management and diabetes, cancer therapy, inflammatory bowel disease, and post-viral fatigue.
