Vitiligo is a depigmenting disorder characterized by melanocyte loss, which results in pigment dilution of the skin. Vitiligo is commonly associated with thyroid disorders and thyroid stimulating hormone (TSH) is a sensitive marker to detect thyroid disorders. S100B is damage associated molecular pattern (DAMP) molecule released when there is melanocyte damage.

Background: High prevalence of metabolic abnormalities and poor bone health in ethnic minorties may stem from differences in body composition and alterations in endocrine milieu. South Asian Indians (SAIs) are at greater risk for metabolic syndrome (MetS) and poor bone health than Caucasians. Often these differences are reported later in life and/or in a resident immigrant population compared to a Caucasian population.

High-dose vitamin D supplementation can increase total osteocalcin concentrations that may reduce insulin resistance in individuals at risk for prediabetes or diabetes mellitus. Magnesium is a cofactor in vitamin D metabolism and activation. The purpose of this study was to determine the combined effect of vitamin D and magnesium supplementation on total osteocalcin concentrations, glycemic indices, and other bone turnover markers after a 12-week intervention in individuals who were overweight and obese, but otherwise healthy.

Background: The long-term impact of vitamin D deficiency and metabolic syndrome (MetS) on cardiovascular disease (CVD) and all-cause mortality are still a matter of debate.

Aim: To test the hypotheses that lower serum 25 hydroxyvitamin D [25(OH)D] concentrations (a marker of vitamin D level) and MetS have a long-term impact on the risk of CVD and all-cause mortality, and individuals with vitamin D deficiency can be identified by multiple factors.

Methods: A sample of 9094 adults, 20 to 90 years of age, who participated in the Third National Health and Nutrition Examination Survey (NHANES III, 1988 to 1994) were followed through December 2015 was analyzed.

Objective: Poor vitamin D and magnesium status is observed in individuals who are overweight and obese (Owt/Ob) and is often associated with a heightened risk of cardiovascular disease. Magnesium is a cofactor that assists vitamin D metabolism. We aimed to determine the efficacy of a combined magnesium and vitamin D regimen compared with vitamin D only on increasing serum 25-hydroxyvitamin D (25OHD) concentrations and the effects of these supplements on cardiometabolic outcomes.

Objective: Higher protein intake during weight loss is associated with better health outcomes, but whether this is because of improved diet quality is not known. The purpose of this study was to examine how the change in self-selected protein intake during caloric restriction (CR) alters diet quality and lean body mass (LBM).

Methods: In this analysis of pooled data from multiple weight loss trials, 207 adults with overweight or obesity were examined before and during 6 months of CR (approximately 10 food records/person).

Bone is a flexible and electro active tissue that is vulnerable to various traumatic injuries. The self-healing of damaged bone tissue towards reconstruction is limited due to the lack of proper niche compliances. Nevertheless, the classical grafting techniques like autograft/allograft for bone repair pose challenges like bacterial infections and donor-site morbidity with unsatisfactory outcomes.

Magnesium (Mg) intake is an important indication of an individual's Mg status, but no validated food frequency questionnaire (FFQ) to assess intake currently exists. The purpose of this study was to develop and investigate the validity of a semi-quantitative Mg food frequency questionnaire (MgFFQ) against a 14-day food diary to assess average daily Mg intakes. In this cross-sectional study, 135 adults aged 18 to 75 completed the 33-item MgFFQ and a 14-day food diary to assess their Mg intakes.

Vitamin D metabolism is dependent on magnesium (Mg) as a cofactor; therefore, poor Mg status may alter the relationship between vitamin D metabolite serum 25-hydroxyvitamin D (s25OHD) and serum parathyroid hormone (sPTH). We hypothesized that low dietary Mg intake may alter sPTH response to s25OHD in a population with excess body weight, thereby leading to a worsening of cardiometabolic health. To explore this hypothesis, we conducted a cross-sectional study on adults who were either overweight or obese (owt/ob).

Purpose Of Review: The purpose of this review is to discuss the current knowledge about major bone regulating hormones vitamin D, parathyroid hormone (PTH), estrogen and bone metabolism markers osteocalcin (OC), bone-specific alkaline phosphatase (BAP), N-terminal propeptide of type 1 collagen (P1NP), and c-terminal type 1 collagen (CTX) and their mechanistic effects on cardiometabolic health.

Recent Findings: Bone regulating hormones, nutrients, and turnover markers influence different aspects of cardiometabolic health including body composition, cardiovascular function, and glycemic control. While most observational research supports a relationship between bone as an endocrine organ and cardiometabolic outcomes, there are limited human clinical trials to strengthen a causal link between the two.

When deceptive suspects are unaware of the evidence the police hold against them, they contradict that evidence more than truthful suspects do-a useful cue to deception. But given that, over time, truthful suspects might forget the past and also contradict the evidence, how effective are lie detection techniques that rely on such inconsistencies when suspects are questioned months after a crime? In Experiment 1, people committed a theft (liars) or a benign activity (truth-tellers) in a university bookshop. Shortly after or 2 months later, we questioned them about their bookshop visit without informing them of the evidence implicating them in the theft.

Article Synopsis
  • Dermatosis papulosa nigra (DPN) is a benign skin condition mainly found in dark-skinned individuals, particularly Asians and African Americans, but there is a lack of substantial research on it.
  • A study conducted at Father Muller Medical College involved 100 patients to investigate the clinical features, and to use histopathology and dermoscopy for more in-depth analysis of DPN.
  • Results indicated an earlier onset of lesions in patients, significant associations like a female preponderance and sun exposure, and histopathological findings confirmed the lesions' benign nature, with dermoscopy proving to be an effective diagnostic tool.
