A multicenter, open-label, randomized, controlled superiority trial with 18 months of follow-up was conducted to investigate whether oral zinc supplementation could further promote spermatogenesis in males with isolated hypogonadotropic hypogonadism (IHH) receiving sequential purified urinary follicular-stimulating hormone/human chorionic gonadotropin (uFSH/hCG) replacement. Sixty-seven Chinese male IHH patients were recruited from the Departments of Endocrinology in eight tertiary hospitals and randomly allocated into the sequential uFSH/hCG group (Group A, n = 34) or the sequential uFSH plus zinc supplementation group (Group B, n = 33)...

OBJECTIVE: Renal conservation (retention) of fluid might affect the outcome of hospital care and can be indicated by increased urinary concentrations of metabolic waste products. We obtained a reference material for further studies by exploring the prevalence of fluid retention in a healthy population. METHODS: Spot urine sampling was performed in 300 healthy hospital workers. A previously validated algorithm summarized the urine-specific gravity, osmolality, creatinine, and color to a fluid retention index (FRI), where 4...

Today's doping tests involving longitudinal monitoring of steroid profiles are difficult in women. Women have more complex hormonal fluctuations than men and commonly take drugs such as hormonal contraceptives that are shown to affect biomarkers used in these doping tests. In this study we followed six women's urinary steroid profile during one menstrual cycle, including both glucuronides and sulfate conjugated fractions. Additionally, we studied what happens to the steroidal module of the athlete biological passport (ABP) after administration of an emergency contraceptive (levonorgestrel, NorLevo®)...

BACKGROUND: Cadmium is a human lung carcinogen, and recent evidence suggests it may play a role in hormone-related cancers because of its estrogenic activity. Case-control studies consistently show higher cadmium concentrations in urine from women diagnosed with breast cancer compared with control women. Our aim was to investigate the association between urinary cadmium and breast cancer in a prospective design. METHODS: We conducted a case-cohort study using the population-based Danish Diet Cancer and Health Cohort...

CONTEXT: Among women with a single, recent pregnancy loss, daily preconception low-dose aspirin (LDA) increased the live birth rate with no effect on pregnancy loss. The mechanism underlying this effect is unclear, but it may work through ovulation. OBJECTIVE: We estimated the effect of LDA on the per-cycle risk of anovulation among eumenorrheic women. DESIGN: The Effects of Aspirin in Gestation and Reproduction trial, a multi-center, randomized, double-blind, placebo-controlled trial of daily LDA on reproductive outcomes...

Cardiovascular (CV) risk assessment is not easy in chronic kidney disease (CKD) patients. Age, male sex, race, family history of CV disease, smoking status and diabetes should be considered as CV risk factors as the general population. It is also accepted that hypertension (HTN) is associated with the greater risk of CV complications in this population. However, there are some concerns in this issue.First, supporting evidence for specific blood pressure (BP) targets in CKD is scarce. Many observational studies reported a J-shaped association between BP level and CV mortality unlike a linear association in the general population...

OBJECTIVE: Obesity is associated with a high risk of hypertension and is characterized by hyperaldosteronism and hypercortisolism. We have previously reported that patients with resistant hypertension (RHTN), defined as blood pressure (BP) that remains above goal in spite of the concurrent use of 3 antihypertensive agents of different classes, have a high prevalence of hyperaldosteronism that is positively correlated with body mass index (BMI). Experimental studies indicate that adipocytes secrete a as yet undetermined factor that stimulates aldosterone and cortisol release...

OBJECTIVE: Disorders of mineral metabolism predicted incidence of cardiovascular events in various clinical settings, possibly because that arterial stiffness mediate this pathway in part. We investigated the interrelationship between mineral metabolism factors and carotid-femoral PWV, and compared the effect sizes of blood pressure (BP) and mineral factors with carotid-femoral PWV in untreated Chinese. DESIGN AND METHOD: Consecutive untreated outpatients referred for ambulatory BP monitoring were recruited...

OBJECTIVE: Identify the earliest hormonal, electrolyte and gene expression responses to a saline infusion before compensatory mechanisms are activated and relate these responses to delayed sodium excretion. DESIGN AND METHOD: 233 normotensive subjects with a strong positive family history of hypertension, ages 21-65, were studied on a low sodium diet before, during and after a 2-hour, 2-liter saline infusion. Plasma and urine hormones of the renin-angiotensin-aldosterone, catecholamine, uric acid, kallikrein, and cortisol pathways, microalbumin, and urine and plasma electrolytes were measured...

BACKGROUND: Growth hormone (GH) has many direct and indirect actions and roles including substrate regulation and priming of some cells of the immune system, and the expected aspects of growth and repair. Different concentrations in human body fluids reflect the exercise-induced growth hormone response (EIGR) after exercise. In populations such as elite athletes, the invasive nature of venous sampling is poorly accepted. Thus, this study examines possible viable alternatives such as urine and saliva samples and the GH concentration...

We herein present the findings of a 42-year-old woman with either adrenal pheochromocytoma or intraadrenal paraganglioma that simultaneously secreted somatostatin, thus mimicking insulin-dependent diabetes mellitus. Pheochromocytoma was clinically diagnosed based on scintigraphy, elevated catecholamine levels, and finally a histopathological analysis of resected specimens. The patient had diabetic ketosis, requiring 40 U insulin for treatment. Following laparoscopic adrenalectomy, insulin therapy was discontinued and the urinary c-peptide levels changed from 5...
