Background: Adequate sex steroid hormone concentrations are essential for normal fetal genital development in early pregnancy. Our previous study demonstrated an inverse relationship between third trimester di-ethyl hexyl (DEHP) phthalate exposure and total testosterone (TT) concentrations. Here, we examine early pregnancy phthalates, sex steroid hormone concentrations, and newborn reproductive outcomes. Methods: We examined associations between urinary phthalate metabolite concentrations in early pregnancy and serum free testosterone (FT), TT, estrone (E1), and estradiol (E2) in 591 woman/infant dyads in The Infant Development and Environment Study; we also examined relationships between hormones and newborn genital outcomes using multiple regression models with covariate adjustment...

Context: The P450 enzyme CYP24A1 is the principal inactivator of vitamin D metabolites. Biallelic loss-of-function mutations in CYP24A1 are associated with elevated serum levels of 1,25-dihydroxyvitamin D3 with consequent hypercalcemia and hypercalciuria, and represent the most common form of idiopathic infantile hypercalcemia (IIH). Current management strategies for this condition include a low calcium diet, reduced dietary vitamin D intake and limited sunlight exposure. CYP3A4 is a P450 enzyme that inactivates many drugs and xenobiotics and may represent an alternative pathway for inactivation of vitamin D metabolites...

Context: Fibroblast growth factor 23 (FGF23) is a critical determinant of phosphate homeostasis. The role of FGF23, however, in regulating physiologic changes in serum phosphate and renal phosphate handling across childhood is not well-described. In addition, animal models have suggested a role for FGF23 in regulating renal calcium excretion. Objective: To assess changes in FGF23 concentrations across childhood in relation to changes in mineral ions and hormones of mineral ion homeostasis...

Sex hormone levels and timing of sexual maturation are considered important markers for health status of adolescents in puberty, and previous research suggests they might be influenced by metal exposure. In three campaigns of the Flemish Environment and Health Study (FLEHS I 2002-2006; FLEHS II 2007-2011 and FLEHS III 2012-2015), data were collected on internal exposure to metals (Cd, Cu, Pb, Cr, Mn, Tl, Ni, Sb, Hg, As and As species) and sexual maturation in 2671 14-15years old adolescents. All metals were measured in blood and/or urine, except total- and methylmercury which were measured in hair samples...

Repeated surveys of prostate cancer (PCa) patients indicate that their prevalence of depression is well above that for their non-PCa peers. Although standard first-line treatments for depression are only about 35% effective, some recent comments have suggested that a focus upon the possible correlates (factors that aggravate or mediate depression) might help improve treatment efficacy. To investigate this issue, 144 10-year PCa survivors were asked about the frequency of urinary incontinence, a common side effect of some PCa treatments...

BACKGROUND: Our previous study showed that nephrolithiasis is a common complication in ulcerative colitis patients after ileal pouch anal anastomosis (IPAA). However, the pathogenesis of nephrolithiasis in IPAA patients has not been studied. The aim of this study was to compare urine and serum metabolic compositions in IPAA patients with nephrolithiasis and controls with IPAA and no nephrolithiasis. METHODS: Using cross-sectional study design, serum and 24-hour urine metabolic compositions were compared between IPAA patients with nephrolithiasis (the study group) and those without (the control group)...

The natriuretic hormone CCK exhibits its gene transcripts in total kidney extracts. To test the possibility of CCK acting as an intrarenal mediator of sodium excretion, we examined mouse kidneys by: (i) an in situ hybridization technique for CCK mRNA in animals fed a normal or a high-sodium diet; (ii) immuno-electron microscopy for the CCK peptide, (iii) an in situ hybridization method and immunohistochemistry for the CCK-specific receptor CCKAR; (iv) confocal image analysis of receptor-mediated Ca2+ responses in isolated renal tubules; and (v) metabolic cage experiments for the measurement of urinary sodium excretion in high salt-fed mice either treated or untreated with the CCKAR antagonist lorglumide...

BACKGROUND: Physiological changes in pregnancy result in increased iodine demand, which may not be met in areas of mild-to-moderate iodine deficiency or borderline sufficiency. As a pregnant woman is the only source of thyroid hormones for her child during early gestation, iodine deficiency-induced hypothyroxinemia may have deleterious effects on fetal development. OBJECTIVE: To present the current approach to iodine deficiency and its prophylaxis during pregnancy...

BACKGROUND: We examined the thyroid function of non-dialysis-dependent chronic kidney disease (CKD) patients in Japan. METHODS: Serum-free thyroxine, free triiodothyronine, thyroid-stimulating hormone (TSH), and thyroglobulin (Tg) levels were evaluated in 37 CKD patients. CKD was defined as sustained kidney damage for more than 3 months and was classified as CKD 1+2 (n = 11), 3+4 (n = 10), or 5 (n = 16), which were defined by glomerular filtration rates of ≥ 60, 15 - 59, or < 15 mL/min/1...

As the prevalence of chronic kidney disease (CKD) increases and the population ages, there is an imperative to offer cost effective and patient specific therapeutic options for the management of advanced CKD. In cases where there is a desire to avoid or delay renal replacement therapy, conservative options need to be defined and strategies for delaying the need for renal replacement therapy should be offered. CKD-mineral bone disorders (MBD) refers to the constellation of disturbances in abnormal bone and soft tissue calcification along with abnormalities, in phosphorus, calcium, parathyroid hormone, vitamin D, and FGF-23...

PURPOSE: Iodine deficiency affects 30% of populations worldwide. The amount of thyroglobulin (Tg) in blood increases in iodine deficiency and also in iodine excess. Tg is considered as a sensitive index of iodine status in groups of children and adults, but its usefulness for individuals is unknown. The aim of this study was to determine the diagnostic performance of Tg as an index of iodine status in individual adults. METHODS: Adults aged 18-40 years (n = 151) provided five spot urine samples for the measurement of urinary iodine concentration expressed as μg/L (UIC), μg/g of creatinine (I:Cre), and μg/day (estimated UIE); the mean of the five samples was used as the reference standard...

Resveratrol possesses several beneficial metabolic effects in rodents, while the effects of resveratrol in humans remain unclear. Therefore, we performed a non-targeted comprehensive metabolomic analysis on blood, urine, adipose tissue, and skeletal muscle tissue in middle-aged men with metabolic syndrome randomized to either resveratrol or placebo treatment for four months. Changes in steroid hormones across all four matrices were the most pronounced changes observed. Resveratrol treatment reduced sulfated androgen precursors in blood, adipose tissue, and muscle tissue, and increased these metabolites in urine...

BACKGROUND: Endometriosis is a disease that affects 7-10% of reproductive-age women. When its diagnosis is delayed, its management becomes more difficult. Both for earlier detection and for therapeutic follow-up, discovering noninvasive biological markers with good specificity for this disease is a promising aspect of its research. We analyzed the recent data in the literature regarding these markers to determine which were worth following. MATERIALS AND METHODS: This literature review focused on medical data reported in the last 6 years (2011-2016)...
