Probiotics Supplementation on Infections in Athletes
It is well established that physical activity (PA) can have beneficial effects on the whole human body and strength its immune defenses. In fact, scientific evidence has established that regular PA is effective in the prevention of various chronic diseases, such as cardiovascular diseases, diabetes, cancer, hypertension, obesity, depression, osteoporosis, and premature death. However, the effects of PA can be different depending on its intensity and duration. In fact, during heavy training and competitions, a higher incidence of gastrointestinal (GI) disorders, such as diarrhea and heartburn, and upper respiratory tract infections (URTIs) can occur. This is due to acute post-exercise immune breakdowns and chronic suppression of immune factors, dependent on frequent strenuous exercise. Therefore, reducing these symptoms in athletes becomes a top priority. Evidence shows that probiotics could be useful in reducing the risk of development or the severity of GI or URT infections, but firther research in this field is still needed.

Dietary Supplements on Inflammatory Markers and SARS-CoV-2 Infection
A key characteristic of severe presentations of acute SARS-CoV-2 infection involves overactive host inflammatory responses, with a substantial proportion of severe outcomes such as hospitalizations and deaths from COVID-19 linked to hyper-inflammation. Inflammation and oxidative stress play pivotal roles in the progression of infectious diseases including COVID-19. Evidence suggests that high sensitivity (hs) C-reactive protein (CRP), interleukin (IL)-6, and matrix metalloproteinases (MMPs) are among the most important biomarkers of COVID-19 severity, similar to the chronic conditions involved in vascular aging. Lactate dehydrogenase (LDH) and hsCRP are also biomarkers of respiratory failure in patients with COVID-19. Furthermore, it is well established that elevated levels of other inflammatory markers are common in COVID-19 patients. These markers include IL-1β, IL-7, IL-8, IL-18, interferon (IFN)-γ, tumor necrosis factor (TNF)-α, procalcitonin (PCT), serum ferritin, and erythrocyte sedimentation rate (ESR).

Dietary Salt Restriction and MDP for Cardiometabolic Health
The dietary restriction of salt intake and the adhesion to Mediterranean dietary pattern (MDP) are among the most recommended lifestyle modifications for the prevention of cardiovascular diseases. A large amount of evidence supports these recommendations. Likewise, findings from observational and clinical studies suggest a causal role of excess salt intake in blood pressure increase, cardiovascular organ damage, and the incidence of cardiovascular diseases. In this context, it is also conceivable that the beneficial effects of these two dietary patterns overlap because Mediterranean dietary patterns are typically characterized by a large consumption of plant-based foods with low sodium content. However, there is little data on this issue, and heterogeneous results are available on the relationship between adherence to salt restriction and to Mediterranean dietary patterns.

Telehealth Nutrition Care During COVID-19
Widespread transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has resulted in a global COVID-19 pandemic that is straining medical resources worldwide. In the United States (US), hospitals and clinics are challenged to accommodate surging patient populations and care needs while preventing further infection spread. Under such conditions, meeting with patients via telehealth technology is a practical way to help maintain meaningful contact while mitigating SARS-CoV-2 transmission. The application of telehealth to nutrition care can, in turn, contribute to better outcomes and lower burdens on healthcare resources. To identify trends in telehealth nutrition care before and during the pandemic, we emailed a 20-question, qualitative structured survey to approximately 200 registered dietitian nutritionists (RDNs) from hospitals and clinics that have participated in the Malnutrition Quality Improvement Initiative (MQii). RDN respondents reported increased use of telehealth-based care for nutritionally at-risk patients during the pandemic. They suggested that use of such telehealth nutrition programs supported positive patient outcomes, and some of their sites planned to continue the telehealth-based nutrition visits in post-pandemic care. Nutrition care by telehealth technology has the potential to improve care provided by practicing RDNs, such as by reducing no-show rates and increasing retention as well as improving health outcomes for patients. We therefore call on healthcare professionals and legislative leaders to implement policy and funding changes that will support improved access to nutrition care via telehealth.

Oxidative Stress and Cardiovascular Diseases
Cardiovascular diseases (CVD) are complex entities with heterogenous pathophysiologic mechanisms and increased oxidative stress has been viewed as one of the potential common etiologies. A fine balance between the presence of reactive oxygen species (ROS) and antioxidants is essential for the proper normal functioning of the cell. A basal concentration of ROS is indispensable for the manifestation of cellular functions, whereas excessive levels of ROS cause damage to cellular macromolecules such as DNA, lipids and proteins, eventually leading to necrosis and apoptotic cell death. CVD is the main cause of death worldwide with several conditions being affected by oxidative stress. Increased ROS lead to decreased nitric oxide availability and vasoconstriction, promoting arterial hypertension. ROS also negatively influence myocardial calcium handling, causing arrhythmia, and augment cardiac remodeling by inducing hypertrophic signaling and apoptosis. Finally, ROS have also been shown to promote atherosclerotic plaque formation.

Mediterranean Diet on Sleep
The Mediterranean diet is a plant-based, antioxidant-rich, unsaturated fat dietary pattern that has been consistently associated with lower rates of noncommunicable diseases and total mortality, so that it is considered one of the healthiest dietary patterns. Recent studies have demonstrated that another health parameter favorably influenced by the Mediterranean diet is sleep, which is an essential component of life.

Diet and Ovulation Disorders in Women
Female infertility is commonly due to ovulation disorders. They are mostly related to polycystic ovary syndrome, which is currently viewed as one of the most common endocrine disorders in women of reproductive age. Ovulation-related female fertility is influenced by multiple factors which may include: age, smoking cigarettes, stress, use of psychoactive substances, and physical activity. Moreover, diet-related factors play an important role in the regulation of ovulation. Dietary components that exert a positive influence on ovulation include: carbohydrate products with low glycemic index, plant protein, monounsaturated and polyunsaturated fatty acids, folic acid, vitamin D, antioxidants, and iron. A diet based on the structure of the Mediterranean diet also seems beneficial. Components that have a negative influence mostly include high glycemic index carbohydrates, large amounts of animal protein, saturated fatty acids, and trans fatty acids, which are typically found in the Western model of nutrition.

Bitter Melon in Breast and Gynecological Cancer
Bitter melon, bitter gourd, karela, or Momordica charantia, is a vine belonging to the Cucurbitaceae family, which is widely cultivated in Asian, African, and South American countries. More precisely, it is a rich source of phytochemicals and has the highest nutritional value among cucurbits. Its biological activity may be mainly attributed to its major chemical constituents: cucurbitane-type triterpenoids, cucurbitane-type triterpene glycosides and their aglycones, flavonoids, phenolic acids, fatty acids, essential oils, lectins, amino acids, goyasaponins, sterols, as well as several proteins. The proportion of these chemical constituents varies, depending on the different varieties of bitter melon, the different origins and cultivation conditions, or the harvest times. Bitter melon extract and its active ingredients have been extensively studied in diverse cell line-based and animal models and reported to exhibit promising effects on the chemoprevention and therapy of skin, brain, oral, lung, liver, colon, stomach, blood, prostate, renal, and pancreatic cancers. The molecular mechanisms of cancer prevention and therapy do not seem to differ among the different cancer entities, with bitter melon enhancing Reactive Oxygen Species (ROS) production, modulating the cell membrane, inducing apoptosis and autophagy, causing epigenetic modifications, as well as interacting with the DNA, the RNA, or numerous proteins.

Proanthocyanidins and Anthocyanins in Nicotine-Induced NSCLC Treatment
In traditional medicine, different parts of plants, including fruits, have been used for their anti-inflammatory and anti-oxidative properties. Plant-based foods, such as fruits, seeds and vegetables, are used for therapeutic purposes due to the presence of flavonoid compounds. Proanthocyanidins (PCs) and anthocyanins (ACNs) are the major distributed flavonoid pigments in plants, which have therapeutic potential against certain chronic diseases. PCs and ACNs derived from plant-based foods and/or medicinal plants at different nontoxic concentrations have shown anti-non-small cell lung cancer (NSCLC) activity in vitro/in vivo models through inhibiting proliferation, invasion/migration, metastasis and angiogenesis and by activating apoptosis/autophagy-related mechanisms.

Beta-Glucans of Cereals
β-glucans are a polymeric dietary fiber characterized by β-(1,3) and β-(1,4) glycosidic bonds between glucose monomers. They are often used as thickeners, stabilizers, and fat substitutes in foods. The functional and technological quality of β-glucans is attributed to their origin/source, molecular weight, and structural properties. In particular, physical treatments such as drying, cooking, freezing, and refrigeration influence their molecular, morphological, and rheological characteristics. In addition to their useful technical qualities, β-glucans are recognized for their numerous beneficial impacts on human health.

Curcumin and Bladder Cancer
The most common type of bladder cancer (BC) is urothelial carcinoma arising from stratified epithelium-urothelium. Layers of cells are arranged into strata perched on the basement membrane (BM), then on lax connective tissue, followed by the muscular part of the bladder wall. The breeching of the urothelial BM, facilitated by an aberrant activation of matrix metalloproteinases (MMP) is particularly perilous. Inhibition of activation of these proteinases constitutes a logic opportunity to restrain progression. Recent studies revealed significant anticancer potential of natural phytochemicals. Especially, curcumin has emerged as a one of the most promising phytochemicals and showed its efficacy in several human malignancies.
