Recent reports estimate that 0.6% of adults in the United States, or approximately 1.4 million persons, identify as transgender. Despite gains in rights and media attention, the reality is that transgender persons experience health disparities, and a dearth of research and evidence-based guidelines remains regarding their specific health needs. The lack of research to characterize cardiovascular disease (CVD) and CVD risk factors in transgender populations receiving cross-sex hormone therapy (CSHT) limits appropriate primary and specialty care...

Acquired idiopathic chylous ascites is extremely rare in women of reproductive age. This is the first report describing successful infertility and pregnancy management in a patient with idiopathic chylous ascites. A 23-year-old woman presented with abdominal distention and was diagnosed with idiopathic fluid collection. A lymphogram revealed lymphatic leakage from the right renal hilum. Lymphatic-venous anastomosis of the thoracic duct was performed thrice, but the chylous ascites persisted. In vitro fertilization was performed because natural conception was not possible...

BACKGROUND: Body size in early life is inversely associated with adult breast cancer (BC) risk, but it is unclear whether the associations differ by tumor characteristics. METHODS: In a pooled analysis of two Swedish population-based studies consisting of 6731 invasive BC cases and 28,705 age-matched cancer-free controls, we examined the associations between body size in early life and BC risk. Self-reported body sizes at ages 7 and 18 years were collected by a validated nine-level pictogram (aggregated into three categories: small, medium and large)...

Drug induced bone diseases concerns : induced osteoporosis, induced osteomalacia (by loss of calcium, phosphate or vitamin D) and induced sarcopenia. Some of these drugs are well known, such as anti-hormones, corticotherapy (which could induce all of osteoporosis, osteomalacia and sarcopenia). In the present article, we will focus on 3 others less known but frequently used drugs : iron replacement, proton pump inhibitors therapy, and serotonin reuptake inhibitor antidepressants treatment. For each of them we will discuss the pathophysiological mechanism leading to bone fragility as well as the recommendations of prevention / management to be proposed in case of absolute necessity of the treatment...

Complete androgen insensitivity syndrome (CAIS) is due to complete androgen resistance in androgen-dependent tissues. Since androgens are involved in growth, development, and mass maintenance of the skeleton, bone health may be a relevant clinical issue for improving quality of life of women living with CAIS. Bone mineral density (BMD) in women with CAIS and intact gonads has been reported in a normal range, although exceptions are known showing a low BMD mainly at the lumbar level. In women with CAIS and removed gonads, BMD is usually reduced at both the lumbar spine and femoral neck...

3β,7α,15α-Trihydroxy-5-androsten-17-one (7α,15α-diOH-DHEA) is a key intermediate of the novel oral contraceptive "Yasmin" (widely used in birth control pills and postmenopausal hormone replacement therapy pills; the active ingredient is drospirenone). It can be synthesized from dehydroepiandrosterone (DHEA) by microbial dihydroxylation at the C7 and C15 positions. Here we describe the method of bioconversion from DHEA into 7α,15α-diOH-DHEA by Colletotrichum lini. Using 6 g/L DHEA as a substrate, the DHEA conversion and the 7α,15α-diOH-DHEA molar yield were 72...

The rationale of "green pesticides" in food security is to use information about endogenous hormones of pest insects to make peptide mimetics that will act against the pest insects to alter their behaviour or physiology, while taking care not to harm beneficial insects or other organisms in the food chain. Such "green" insecticides are designed thus, on the basis of neuropeptide ligand-receptor interaction and it is of paramount interest to have finally a mimetic at hand that is harmful only to pest insects...

Gonadotropin-releasing hormone agonists, used widely in the treatment of metastatic prostate cancer and hormone receptor-positive breast cancer, are associated with a rare but potentially fatal outcome of pituitary apoplexy (PA). An 85-year-old man presented with sudden onset of headache, left eye pain, sensitivity to light, nausea and vomiting. The symptoms started 4 hours after initiation of leuprolide therapy for treatment of recently diagnosed metastatic prostate carcinoma. Radiological imaging of the brain demonstrated a heterogeneously enlarged pituitary gland measuring 19×16×13 mm and T1-hyperintense signal compatible with pituitary haemorrhage...

Due to lower female incidence, estimates of exogenous and endogenous hormonal factors in head and neck cancers (HNCs, comprising cancers of the oral cavity, oropharynx, hypopharynx, and larynx) among women have been inconsistent and unable to account for key HNC risk factors. We pooled data from 11 studies from Europe, North America, and Japan. Analysis included 1572 HNC female cases and 4343 controls. Pooled odds ratios (ORs) estimates and their 95% confidence intervals (CIs) were calculated using multivariate logistic regression models adjusting for tobacco smoking and alcohol drinking...

Dry eye disease (DED) is a multifactorial ocular surface disease that causes symptoms of ocular pain, discomfort, and decreased visual acuity. It significantly affects quality of life of patients. It is more prevalent in the females and is being specifically in the menopausal and postmenopausal age group. This is believed to be due to the changes in balance of sex hormones. Sex hormones - estrogens and androgens - influence production of all components of the tear film including aqueous layer, lipid, and mucin...

INTRODUCTION: Acute kidney injury (AKI) affects more than 50% of critically ill patients. The formation of calcitriol, the active vitamin D metabolite, from the main inactive circulating form, 25-hydroxyvitamin D (25(OH)D), occurs primarily in the proximal renal tubules. This results in a theoretical basis for reduction in levels of calcitriol over the course of an AKI. Vitamin D deficiency is highly prevalent in critically ill adults, and has been associated with increased rates of sepsis, longer hospital stays and increased mortality...

A 68-year-old man with a background of hypertension and type 2 diabetes presented with fluctuating symptoms of muscle aches and pains and tiredness. His initial work-up for the possibility of hypercortisolaemia showed a completely variable pattern, with 24-hour cortisol excretion and serum cortisol post 1 mg dexamethasone suppression test ranging from normal to significantly elevated. A series of salivary cortisol with symptom diary confirmed the cyclical nature of hypercortisolaemia, and his concomitant adrenocorticotropic hormone (ACTH) levels were elevated...

Age and female sex have repeatedly been identified as gallstone determinants but the underlying mechanisms are not clarified. The objectives of this study were to determine if changes with age in physiology, lifestyle, or reproductive hormones were associated with incident gallstones. A cohort study of a general population random sample (N = 2366) aged 30-60 years was performed. Participants were ultrasound screened for gallstones in 1982-84 and again in 1993-94. Lifestyle data and blood samples were obtained and re-analyzed in 2004...

REVIEW
Vladimir Lažetić, David S Fay
Molting is an essential developmental process for the majority of animal species on Earth. During the molting process, which is a specialized form of extracellular matrix (ECM) remodeling, the old apical ECM, or cuticle, is replaced with a new one. Many of the genes and pathways identified as important for molting in nematodes are highly conserved in vertebrates and include regulators and components of vesicular trafficking, steroid-hormone signaling, developmental timers, and hedgehog-like signaling. In this review, we discuss what is known about molting, with a focus on studies in Caenorhabditis elegans...

There is a frequently encountered subset of hypothyroid patients who are refractory to standard thyroid hormone replacement treatment and require unexpectedly high doses of levothyroxine. In addition to clinical situations where hypothyroid patients are non-compliant, or where there is the possibility of excipient-induced disease exacerbation (gluten/celiac disease), therapeutic failure may be due to impaired absorption of the administered drug. The common approach to managing patients with unusual thyroxine needs is to escalate the dose of levothyroxine until targeted TSH levels are achieved...
