Osteoporosis and dermatoporosis: a review on the role of vitamin D.

Osteoporosis (OP) and Dermatoporosis (DP) are expressions of the aging process at the skin and bone levels, respectively. Both conditions are associated with increased morbidity for elderly people, and this requires necessary interventions. They share many common risk factors; among these, vitamin D (VD) deficiency appears to have a role.

Severe impact of late diagnosis of congenital adrenal hyperplasia on gender identity, sexual orientation and function: case report and review of the literature.

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) represents the most frequent form of CAH and of 46, XX disorder of sex development in female newborns. In the majority of cases, particularly in developed countries, female patients suffering from the classic forms of CAH reach the diagnosis at birth or in the early childhood, allowing a prompt treatment with a correct gender assignment. The current manuscript describes an unusual case of an Italian 46-year-old woman, homeborn in the 60s, receiving an extraordinarily late diagnosis of simple virilising classic form of CAH due to 21-OHD, determining a relevant impairment of both physical and psychosexual development.

Craniopharyngioma and Metabolic Syndrome: A 5-Year Follow-Up Single-Center Experience.

Patients with craniopharyngioma often have comorbidities, such as obesity and hypopituitarism. These two conditions affect each other and worsen the quality of life of patients, which lead to a higher risk of morbidity and mortality. In addition, abdominal obesity, measured as waist circumference (WC), is together with other parameters [arterial hypertension, hyperglycemia, hypertriglyceridemia, and reduced levels of high-density lipoprotein (HDL) cholesterol], one of the components of metabolic syndrome (MS).

Treatment of Paget's disease of the bone: long-term effect of neridronate in a real-life setting.

Background: Bisphosphonates represent the gold standard treatment for Paget's disease of bone. Neridronate is a potent bisphosphonate, licensed in Italy for this use, but only few clinical trials have investigated the outcomes of this treatment. The aim of our study was to report our long-term experience with intravenous Neridronate.

Purpose: To examine the MRI diagnostic performance in the assessment of therapeutic response to burosumab in children with X-linked hypophosphatemia (XLH).

Design: Prospective longitudinal open cohort.

Patients: Seventeen children with XLH, average age of 10.

Impact of Long-Term Growth Hormone Replacement Therapy on Metabolic and Cardiovascular Parameters in Adult Growth Hormone Deficiency: Comparison Between Adult and Elderly Patients.

Growth hormone deficiency (GHD) in adults is due to a reduced growth hormone (GH) secretion by the anterior pituitary gland which leads to a well-known syndrome characterized by decreased cognitive function and quality of life (QoL), decreased bone mineral density (BMD), increased central adiposity with a reduction in lean body mass, decreased exercise tolerance, hyperlipidemia and increased predisposition to atherogenesis. Considering some similar features between aging and GHD, it was thought that the relative GH insufficiency of the elderly person could make an important contribution to the fragility of elderly. GH stimulation tests are able to differentiate GHD in elderly patients (EGHD) from the physiological reduction of GH secretion that occurs with aging.

Papillary thyroid carcinoma arising in ectopic thyroid tissue within sternocleidomastoid muscle: a review of current literature.

The prevalence of ectopic thyroid tissue as consequence of an aberrant migration of thyroid during embryogenesis ranges up to 10% in autopsy studies. The differential diagnosis between the relatively rare occurrence of a primary carcinoma arising in ectopic thyroid tissue and the more frequent presence of cervical lymph node metastasis from papillary thyroid carcinoma (PTC) might represent a difficult challenge in the clinical practice. The clinical relevance of these lesions lies in their risk of hidden primary thyroid cancer.

Treatment of Acromegalic Osteopathy in Real-life Clinical Practice: The BAAC (Bone Active Drugs in Acromegaly) Study.

Background: Vertebral fractures (VFs) are a frequent complication of acromegaly, but no studies have been so far published on effectiveness of antiosteoporotic drugs in this clinical setting.

Objective: To evaluate whether in real-life clinical practice bone active drugs may reduce the risk of VFs in patients with active or controlled acromegaly.

Study Design: Retrospective, longitudinal study including 9 tertiary care endocrine units.

The Sun's Vitamin in Adult Patients Affected by Prader-Willi Syndrome.

Prader-Willi syndrome (PWS) is a genetic disorder characterized by hyperphagia with progressive, severe obesity, and an increased risk of obesity-related comorbidities in adult life. Although low dietary vitamin D intake and low 25-hydroxy vitamin D (25OHD) levels are commonly reported in PWS in the context of bone metabolism, the association of low 25OHD levels with fat mass has not been extensively evaluated in PWS adults. The aims of this study were to investigate the following in PWS adults: (1) 25OHD levels and the dietary vitamin D intake; (2) associations among 25OHD levels with anthropometric measurements and fat mass; (3) specific cut-off values for body mass index (BMI) and fat mass predictive of the 25OHD levels.

Vitamin D and Sleep Regulation: Is there a Role for Vitamin D?

Background: Vitamin D exerts multiple pleiotropic effects beyond its role in calcium-phosphate metabolism. Growing evidence suggests an association between hypovitaminosis D and sleep disorders, thus increasing the interest in the role of this vitamin in the regulatory mechanisms of the sleep-wake cycle.

Objective: The study aimed to explore and summarize the current knowledge about the role of vitamin D in sleep regulation and the impact of vitamin D deficiency on sleep disorders.

Bone metabolism, bone mass and structural integrity profile in professional male football players.

Background: Physical exercise plays an important role in bone mineralization as well as factors involved in bone metabolism influence the athletic performance. In European countries, soccer is the most popular sport. The aim of the study was to investigate bone metabolism, bone mass and structural integrity profile in professional male adult football players.

Increased prevalence of overweight and obesity in children with X-linked hypophosphatemia.

Background/aim: X-linked hypophosphatemia (XLH) is a rare disease characterized by low phosphate levels. Scientific evidence points to a link between hypophosphatemia and obesity in general population. The aim of our longitudinal observational study was to investigate the prevalence of obesity and associated factors in a large cohort of children with XLH.

Sex Differences of Vitamin D Status across BMI Classes: An Observational Prospective Cohort Study.

Growing evidence reported that vitamin D deficiency is a common finding in obesity. Vitamin D status also seems to be sex-related, although little is known regarding this association. Therefore, the aim of this study was to investigate the sex-related differences of serum 25OH vitamin D (25OHD) concentrations across body mass index (BMI) classes and, if there were any differences, whether they could be explained by sex-related differences in body composition.

Somatotropic Axis and Obesity: Is There Any Role for the Mediterranean Diet?

Obesity is associated with reduced spontaneous and stimulated growth hormone (GH) secretion and basal insulin-like growth factor I (IGF-1) levels-which in turn is associated with increased prevalence of cardiovascular risk factors. The aim of this study was to investigate: (1) the association of somatotropic axis with cardiometabolic status; (2) the association of somatotropic axis with the Mediterranean diet and nutritional pattern in people with obesity. Cross-sectional observational study was carried out in 200 adult women, aged 36.

Phase Angle: A Possible Biomarker to Quantify Inflammation in Subjects with Obesity and 25(OH)D Deficiency.

Obesity is associated to chronic low-grade metabolic inflammation and hypovitaminosis D. Among extra-skeletal effects, an important role in inflammation has been described for vitamin D (25(OH)D). Phase angle (PhA) is a bioelectrical impedance analysis (BIA) parameter that represents an indicator of cellular health in chronic inflammatory states.

Acromegaly and Heart Failure.

In patients with acromegaly, chronic GH and IGF-I excess commonly causes a specific cardiomyopathy characterized by a concentric cardiac hypertrophy associated with diastolic dysfunction and, in later stages, with systolic dysfunction ending in heart failure in untreated and uncontrolled patients. Additional relevant cardiovascular complications are represented by arterial hypertension, valvulopathies, arrhythmias, and vascular endothelial dysfunction, which, together with the respiratory and metabolic complications, contribute to the development of cardiac disease and the increase cardiovascular risk in acromegaly. Disease duration plays a pivotal role in the determination of acromegalic cardiomyopathy.

Calcium and Vitamin D Supplementation. Myths and Realities with Regard to Cardiovascular Risk.

Vitamin D and calcium are considered crucial for the treatment of bone diseases. Both vitamin D and calcium contribute to bone homeostasis but also preserve muscle health by reducing the risk of falls and fractures. Low vitamin D concentrations result in secondary hyperparathyroidism and contribute to bone loss, although the development of secondary hyperparathyroidism varies, even in patients with severe vitamin D deficiency.

Trimethylamine N-oxide, Mediterranean diet, and nutrition in healthy, normal-weight adults: also a matter of sex?

Objectives: Sex exerts an important influence on food preferences. The Mediterranean diet (MD) is based on the common dietary characteristics and lifestyle behaviors of the Mediterranean countries. Trimethylamine N-oxide (TMAO), a marker of gut dysbiosis linked to the development of atherosclerosis and cardiovascular risk, is mainly dependent on dietary pattern and gut microbiota metabolism.

The lullaby of the sun: the role of vitamin D in sleep disturbance.

Vitamin D is a pro-hormone belonging to the category of the fat-soluble group of vitamins; it is obtained more from solar exposure and in smaller quantities through feeding. Although vitamin D has traditionally been shown to be involved in calcium homeostasis and bone health, recent studies have found a positive association between vitamin D and sleep. In particular, clinical studies in humans indicate that low levels of vitamin D are correlated with poor quality and short sleep duration.

Patient empowerment and the Mediterranean diet as a possible tool to tackle prediabetes associated with overweight or obesity: a pilot study.

Aim: The objective of this study was to investigate the effect of implementation of short-term patient empowerment as applied to Mediterranean diet (MD) adherence on metabolic and anthropometric parameters in prediabetic overweight or obese subjects.

Methods: The sample included 42 subjects with prediabetes, aged 18-75 years and with body mass index (BMI) > 25 kg/m, who received dietary advice on MD by nutritionists during session groups every 2 weeks for 4 months. Data on energy caloric intake and macronutrient consumption were collected using a 7-day food diary record.

Trimethylamine-N-oxide (TMAO) as Novel Potential Biomarker of Early Predictors of Metabolic Syndrome.

There is a mechanistic link between the gut-derived metabolite trimethylamine-N-oxide (TMAO) and obesity-related diseases, suggesting that the TMAO pathway may also be linked to the pathogenesis of obesity. The Visceral Adiposity Index (VAI), a gender-specific indicator of adipose dysfunction, and the Fatty Liver Index (FLI), a predictor of non-alcoholic fatty liver disease (NAFLD), are early predictors of metabolic syndrome (MetS). In this cross-sectional observational study, we investigated TMAO levels in adults stratified according to Body Mass Index (BMI) and the association of TMAO with VAI and FLI.
