Some dietary supplements are recommended to athletes based on data that supports improved exercise performance. Other dietary supplements are not ergogenic per se, but may improve health, adaptation to exercise, or recovery from injury, and so could help athletes to train and/or compete more effectively. In this review, we describe several dietary supplements that may improve health, exercise adaptation, or recovery. Creatine monohydrate may improve: recovery from and adaptation to intense training, recovery from periods of injury with extreme inactivity, cognitive processing, and reduce severity of or enhance recovery from mild traumatic brain injury (mTBI)...

Studies have shown a relationship between maternal periodontal diseases (PDs) and premature delivery. PDs are commonly encountered oral diseases which cause progressive damage to the periodontal ligament and alveolar bones, leading to loss of teeth and oral disabilities. PDs also adversely affect general health by worsening cardiovascular and metabolic diseases. Moreover, maternal PDs are thought to be related to increasing the frequency of preterm-birth with low birth weight (PBLBW) new-borns. Prematurity and immaturity are the leading causes of prenatal and infant mortality and is a major public health problem around the world...

2017 highlights benefits of prevention. Better control of cardiovascular risk reduces the incidence of dementia and monthly high-dose vitamin D the incidence of respiratory infections in nursing home. Pre-operative geriatric assessment lowers by 20% the rate of delirium after hip-fracture surgery and complications in vascular surgery. Deleterious effects are also reported. High-dose vitamin D triples the rate of falls in supplemented residents and doesn't improve gait speed in sedentary men. Widely used in cardiovascular prevention, antithrombotic therapy is associated with an astonishing risk of subdural bleeding that further increases with the number of drugs combined together...

OBJECTIVE: There is a growing body of evidence to substantiate that cutaneous psoriasis is associated with an increased risk for a multitude of systemic disorders. Although there is an extensive array of medical publications regarding psoriasis, the dental literature has almost exclusively been focused on erythema migrans and occasionally, with oral psoriatic mucositis, chronic periodontitis, and psoriatic arthritis of the temporomandibular joint. This report will review the diversity of systemic comorbidities, namely cardiovascular, neurologic, renal, liver, gastrointestinal, pulmonary, endocrine, ocular, arthritic (including temporomandibular joint), nail, cutaneous, and psychologic (including suicide) disorders; neoplasia; infection; dyslipidemia; vitamin D deficiency; substance abuse; higher mortality; and oral mucosal involvement...

Vitamin D functions as a vitamin as well as a hormone. Its major skeletal actions are complemented by varied extra-skeletal functions. During the past decade, association between Vitamin D and its role in various non-skeletal morbidities have been recognized. It plays a role in decreasing the risk of many chronic illnesses like allergies, asthma, autoimmune diseases, diabetes, cancers, infections and cardiovascular disease. We report the case of a middle aged female with chronic quadriparesis and new onset anemia associated with Vitamin D deficiency...

Low circulating 25-hydroxyvitamin D (25OHD) levels are a risk factor for acute respiratory infection (e.g., bronchiolitis) in children. However, little is known about the relation of circulating 25OHD with the many downstream functional molecules in target organs - such as the airway - and with clinical outcomes. In this prospective multicenter study of infants (age <1 year) hospitalized with bronchiolitis, we measured serum 25OHD levels and profiled the metabolome of 144 nasopharyngeal airway samples. Among 254 metabolites identified, we defined a set of 20 metabolites that are related to lower serum 25OHD and higher vitamin D-binding protein levels...

Vitamin D is hypothesized to have a beneficial effect on lung function and respiratory infections. The aim of this study was to assess the relationship of serum 25-hydroxyvitamin D (25(OH)D) concentrations with lung function, airway inflammation and common colds. We performed a cross-sectional analysis in the Netherlands Epidemiology of Obesity (NEO) study, a population-based cohort study. We included participants with measurements of serum 25(OH)D, Forced Expiratory Volume in 1 s (FEV₁), Forced Vital Capacity (FVC), Fractional Exhaled Nitric Oxide (FeNO), and data on self-reported common colds (n = 6138)...

The bovine innate immune system has a strong repertoire of antimicrobial defenses to rapidly attack infectious pathogens that evade physical barriers of the udder. Exploration of the intracrine vitamin D pathway of bovine macrophages has improved understanding of the signals that initiate antimicrobial defenses that protect the udder. In the intracrine vitamin D pathway, pathogen recognition receptors upregulate CYP27B1 mRNA that encodes for the enzyme that converts 25-hydroxyvitamin D [25(OH)D3] to the active vitamin D hormone, 1,25-dihydroxyvitamin D3 [1,25(OH)2D3]...

BACKGROUND: Dengue, one the most important public health problems in tropical and subtropical areas, is the most important mosquito-borne viral infection in humans. In the absence of effective treatment and vaccine against dengue, the active form of vitamin D could play a central role in protection against dengue virus (DENV), the causal agent of dengue. Recently we reported that monocyte-derived macrophages (MDMs) differentiated in the presence of vitamin D, in addition to expressing lower levels of mannose receptor, are less susceptible to DENV infection and produce low levels of pro-inflammatory cytokines, compared to MDMs differentiated in the absence of vitamin D...

The Pleurotus genus is one of most extensively studied white-rot fungi due to its exceptional ligninolytic properties. It is an edible mushroom that possesses biological effects, as it contains important bioactive molecules. It is a rich source of nutrients, particularly proteins, minerals as well as vitamins B, C and D. In basidiomycete fungi, intensive cultivations of edible mushrooms can often be affected by some bacterial, mold and virus diseases that rather frequently cause dramatic production loss. These infections are facilitated by the particular conditions under which mushroom cultivation is commonly carried out such as warm temperatures, humidity, carbon dioxide (CO2) levels and presence of pests...

Hypoparathyroidism is associated with an increased risk of various complications, but only few data are available on risk factors. Using a case-control design, we assessed associations between biochemical findings and risk of different complications within a subpopulation of our previously identified Danish patients. We retrieved all biochemical data available on 431 (81% women) patients from the Central Region of Denmark, covering approximately 20% of the Danish population. Average age of patients was 41 years at time of diagnosis...

BACKGROUND: Hepatitis B virus (HBV) infection is still a serious public health problem. Understanding risk factors associated with development of HBV is greatly important. Numerous studies focus on relationship between vitamin D receptor (VDR) polymorphisms (TaqI, FokI, ApaI, BsmI) and the risk of HBV infection in different ethnic groups. However the results published so far are inconsistent. The aim of this study is to quantify the association between VDR polymorphisms with HBV infection by meta-analysis approach...

BACKGROUND: Vitamin C is an essential water-soluble nutrient which cannot be synthesised or stored by humans. It is a potent antioxidant with anti-inflammatory and immune-supportive roles. Previous research has indicated that vitamin C levels are depleted in critically ill patients. In this study we have assessed plasma vitamin C concentrations in critically ill patients relative to infection status (septic shock or non-septic) and level of inflammation (C-reactive protein concentrations)...
