REVIEW
Donald L Trump, Jeanny B Aragon-Ching
Signaling through the vitamin D receptor has been shown to be biologically active and important in a number of preclinical studies in prostate and other cancers. Epidemiologic data also indicate that vitamin D signaling may be important in the cause and prognosis of prostate and other cancers. These data indicate that perturbation of vitamin D signaling may be a target for the prevention and treatment of prostate cancer. Large studies of vitamin D supplementation will be required to determine whether these observations can be translated into prevention strategies...

PURPOSE OF REVIEW: Patients with inflammatory bowel disease (IBD) are not receiving preventative care services at the same rate as the general population. IBD patients are at increased risk for infections, osteoporosis, and certain malignancies secondary to their disease and as they are on immunosuppressive therapy. They are a younger population and often times consider their gastroenterologist as their primary care physician. In this review, we discuss up-to-date evidence pertaining to vaccine-preventable illnesses in the immunosuppressed IBD patient, screening for bone health, cervical cancer, skin malignancies, psychological wellbeing, and smoking cessation...

The prevalence of vitamin D insufficiency, usually assessed by the analysis of circulating 25-hydroxyvitamin D (25[OH])D), is very high in the aging German population. An important factor that reduces endogenous vitamin D synthesis in older persons is physical inactivity or care-dependency that limits the time spent outside. Additionally, it has been suggested that the age-dependent decline in the glomerular filtration rate is associated with a reduced production of bioactive calcitriol. As this phenomenon is not detectable by the assessment of 25(OH)D, it is necessary to analyze the level of parathyroid hormone as a marker of calcitriol function...

Vitamin D (VD) is a neuroactive steroid crucial for brain development, function and homeostasis. Its deficiency is associated with numerous brain conditions. As such, VD and its variants are routinely taken by a broad of groups with/without known VD deficiency. In contrast, the harmful effects of VD overdose have been poorly studied. Similarly, the developmental stage-specific VD deficiency and overdose have been rarely explored. In the present work, we showed that postnatal VD supplementation enhanced the motor function transiently in the young adult, but not in the older one...

BACKGROUND: The prevalence of type 2 diabetes mellitus (T2DM) is increasing worldwide. T2DM is associated with serious macro- and microvascular complications. In particular, diabetic kidney disease (DKD), which begins with excessive urinary albumin excretion, has a significant impact on affected individuals and is costly to healthcare services. Inhibition of the renin-angiotensin-aldosterone system (RAAS) with angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) significantly reduces albuminuria in diabetes, but this effect is not observed in all those treated...

Most trials of vitamin D supplementation have shown no benefits on bone density (BMD), though severe vitamin D deficiency causes osteomalacia which is associated with profound BMD deficits. Recently, the ViDA-BMD study from New Zealand demonstrated a threshold of baseline 25-hydroxyvitamin D (30 nmol/L) below which vitamin D supplementation did benefit BMD. We have now re-examined data from a similar trial in Aberdeen to determine whether a baseline 25-hydroxyvitamin D threshold of 30 nmol/L is also observed in that database...

PURPOSE OF REVIEW: The purpose of this review is to describe recent advances and changes in the evaluation and management of primary hyperparathyroidism (PHPT). RECENT FINDINGS: Although it has long been recognized that asymptomatic PHPT is associated with bone loss, particularly at cortical skeletal sites when evaluated with dual-energy X-ray absorptiometry, new imaging techniques suggest that trabecular skeletal deterioration as well as clinically silent vertebral fractures and nephrolithiasis are common...

In the past few years, a growing body of clinical evidence has highlighted the risk of vitamin D deficiency in patients with chronic hepatitis C and that vitamin D levels are associated with the course of hepatitis C virus (HCV) infection, adverse effects, and treatment response to peginterferon/ribavirin. Recently, studies have found that vitamin D status is related to drug resistance and increased risk of infection in patients with liver cirrhosis. Vitamin D-related gene polymorphisms have been found to explain the interactions between vitamin D deficiency and HCV infection, offering a new perspective toward understanding the current problems such as the development of insulin resistance and racial differences in sustained virological response...

There is considerable concern on the rise in the incidence of asthma worldwide with statistics in the United Arab Emirates (UAE) indicating that at least 13% of schoolchildren, particularly of Emirati descent, suffer from asthma. With its high rates of hospital admissions, negative socioeconomic impact and significant morbidity, this is a disease that requires optimal guidelines for control and awareness. In this article, we review the current knowledge of asthma in the UAE and draw on studies, especially from the surrounding region, to identify its contributing factors within this population...

OBJECTIVE: Obsessive-compulsive disorder (OCD) is a disabling mental illness for which pharmacological and psychosocial interventions are all too often inadequate. This demonstrates the need for more targeted therapeutics. Recent preclinical and clinical studies have implicated dysfunction of glutamatergic neurotransmission in the pathophysiology of OCD. Moreover there are studies suggesting that neuroimmune abnormalities may play an important role in the pathogenesis of OCD. N-acetyl cysteine (NAC) is a safe and readily available agent that would modify the synaptic release of glutamate in subcortical brain regions via modulation of the cysteine-glutamate antiporter...

Vitamin D deficiency is currently a worldwide epidemic. Middle Eastern countries, including Saudi Arabia, have high vitamin D deficiency prevalence, most prominently among women, despite their plentiful year-round sunshine. Previous research investigating vitamin D status among Saudi women of reproductive age (15-49 years) is scarce, and no study has used a nationally representative sample, so this review quantified overall hypovitaminosis D prevalence among women in Saudi Arabia and explored the associated risk factors...

Background: While it is well known that teriparatide (TPTD) increases bone mineral density (BMD) in osteoporotic patients, it is unknown whether TPTD pretreatment affects BMD after denosumab (DMAb) therapy. Methods: Fifty-seven patients in TPTD-pretreated group and 35 patients in DMAb-alone group had been further analyzed, all of whom were treated by DMAb for 1.5 years. Vitamin D (400 IU) and Ca (600 mg) supplementation was used in all patients. The BMD of lumbar 1-4 vertebrae (L-BMD), bilateral total hips (H-BMD), and bilateral femoral neck (FN-BMD) was quantified at first visit, and at 4, 8, 12, and 18 months after daily TPTD treatment following four times DMAb treatment...
