BACKGROUND: Sickle cell disease is a genetic chronic haemolytic and pro-inflammatory disorder. The clinical manifestations of sickle cell disease result from the presence of mutations on the beta globin genes that generate an abnormal haemoglobin product (called haemoglobin S) within the red blood cell. Sickle cell disease can lead to many complications such as acute chest syndrome, stroke, acute and chronic bone complications (including painful vaso-occlusive crisis, osteomyelitis, osteonecrosis and osteoporosis)...

Estrogen has an impact on the type of lipoproteins and the blood lipid levels, thus protecting the cardiovascular system. Postmenopausal breast cancer patients suffer a significant decrease in estrogen levels due to both physiological changes and the use of drugs, and thus have a higher risk of atherosclerotic cardiovascular diseases. Therefore, strict lipid management is required for postmenopausal breast cancer patients receiving endocrine therapy. However, no guidelines have been developed in terms of lipid management and intervention for postmenopausal breast cancer patients...

Although useful prognostic and predictive insights can be gained from patient and tumour characteristics in early-stage breast cancer, it is not always straightforward to predict the likely risk of recurrence for each individual patient following breast surgery. One of the most difficult challenges faced by clinicians is identifying patients who may benefit most from adjuvant chemotherapy, and distinguishing these cases from those where endocrine therapy may be sufficient for cure. Genomic tests such as the Oncotype DX(®) Breast Recurrence Score(®) Assay have been developed to provide a robust and clinically validated assessment of a patient's individual tumour signature...

Diagnosis of Cushing's syndrome (CS) and identification of the aetiology of hypercortisolism can be challenging. The Endocrine Society clinical practice guidelines recommends one of the four tests for initial screening of CS, namely, urinary-free cortisol, late night salivary cortisol, overnight dexamethasone suppression test or a longer low-dose dexamethasone suppression test, for 48 hours. Confirmation and localisation of CS requires additional biochemical and radiological tests. Radiological evaluation involves different imaging modalities including MRI with or without different radio-nuclear imaging techniques...

Purpose We conducted a retrospective analysis to assess the safety profile of nivolumab monotherapy in patients with advanced melanoma and describe the management of adverse events (AEs) using established safety guidelines. Patients and Methods Safety data were pooled from four studies, including two phase III trials, with patients who received nivolumab 3 mg/kg once every 2 weeks. We evaluated rate of treatment-related AEs, time to onset and resolution of select AEs (those with potential immunologic etiology), and impact of select AEs and suppressive immune-modulating agents (IMs) on antitumor efficacy...

In vitro transactivation bioassays have shown promise as water quality monitoring tools, however their adoption and widespread application has been hindered partly due to a lack of standardized methods and availability of robust, user-friendly technology. In this study, commercially available, division-arrested cell lines were employed to quantitatively screen for endocrine activity of chemicals present in water samples of interest to environmental quality professionals. A single, standardized protocol that included comprehensive quality assurance/quality control (QA/QC) checks was developed for Estrogen and Glucocorticoid Receptor activity (ER and GR, respectively) using a cell-based Fluorescence Resonance Energy Transfer (FRET) assay...

Woo-Chan Park
Historically, endocrine therapy for breast cancer began with ovarian ablation (OA) for the treatment of premenopausal patients. After the identification of estrogen receptors and the development of many antiestrogens, tamoxifen has been approved and used as the standard endocrine therapy for hormonal receptor (HR)-positive premenopausal patients to date. With the development of luteinizing hormone-releasing hormone agonists, the paradigm of endocrine therapy for premenopausal women with HR-positive breast cancer began to change from OA to ovarian function suppression (OFS)...

Surface water, sediment, and fish from Biscayne Bay, coastal wetlands adjacent to the Bay, and canals discharging into the Bay were sampled for determination of baseline contamination in Biscayne National Park. While the number of contaminants detected in canal waters was greater during the wet season than the dry season, no seasonal difference was evident for Biscayne Bay or coastal wetland waters. Estrogen equivalency (as 17β-estradiol equivalents), as predicted by the Yeast Estrogen Screen, for extracts of passive water samplers deployed in canals and wetlands was elevated during the wet relative to the dry season...

INTRODUCTION: Clinical guidelines recommend that patients with hormone receptor (HR)-positive metastatic breast cancer (MBC) should be preferentially treated with endocrine therapy. Fulvestrant (a selective estrogen receptor degrader) is approved for use in these patients following relapse after, or relapse or progression during, antiestrogen therapy. This descriptive study analyzed European treatment patterns for HR-positive MBC in real-world clinical practice. METHODS: The IMS Oncology Analyzer (OA), a retrospective cancer treatment database reporting physician-entered patient case histories, was used to identify records for postmenopausal women with HR-positive MBC from April 1, 2004 to June 30, 2013 in France, Germany, Italy, and Spain...

Phthalate esters (PAEs) are known organic endocrine disruptors. The distribution of 10 PAEs in sediments of Kaohsiung Harbor of Taiwan was studied using organic solvents extraction and quantified by gas chromatography/mass spectrometry. The average concentration of total PAEs (ΣPAEs) in the sediment was 8713±11,454ng/g dw with di-(2-ethylhexyl) phthalate (DEHP) (3630ng/g-dw) and diisononyl phthalate (DiNP) (3497ng/g dw) being the major species, which constitutes of 41.7% and 40.1% of ΣPAEs. PAEs concentration was relatively high near the river mouths, especially in Love River mouth, and diminished toward the harbor...

Vitamin D is indispensable for the maintenance of bone and mineral health. Inadequate vitamin D action increases the risk for various musculoskeletal/mineral events including fracture, fall, secondary hyperparathyroidism, diminished response to antiresorptives, rickets/osteomalacia, and hypocalcemia. Its most common cause in recent years is vitamin D deficiency/insufficiency, clinically defined by low serum 25-hydroxyvitamin D [25(OH)D] level. Guidelines for vitamin D insufficiency/deficiency defined by serum 25(OH)D concentrations have been published all over the world...

Merkel cell carcinoma is a rare neuro-endocrine tumor of skin with a poor prognosis. Data available in literature are scarce. Current treatment for locoregional disease is based on combined treatment by surgery and radiotherapy. However these treatments are controversial. The aim of the present review is to sum up the different available studies and to compare national and international guidelines.

BACKGROUND: Multidisciplinary team (MDT) meetings are used to optimise expert decision-making about treatment options, but such expertise is not digitally transferable between centres. To help standardise medical decision-making, we developed a machine learning model designed to predict MDT decisions about adjuvant breast cancer treatments. METHODS: We analysed MDT decisions regarding adjuvant systemic therapy for 1065 breast cancer cases over eight years. Machine learning classifiers with and without bootstrap aggregation were correlated with MDT decisions (recommended, not recommended, or discussable) regarding adjuvant cytotoxic, endocrine and biologic/targeted therapies, then tested for predictability using stratified ten-fold cross-validations...

Endocrine tumor syndromes, eg, multiple endocrine neoplasia types 1 and 2, were among the first recognized hereditary predisposition syndromes to tumor development. Over time, the number of endocrine tumor syndromes has significantly expanded, eg, with the recent inclusion of hereditary paraganglioma syndromes. Associations of non-endocrine tumors with hereditary endocrine tumor syndromes and endocrine tumors with non-classical endocrine tumor syndromes have emerged. These findings have certainly expanded the scope of care, necessitating a multidisciplinary approach by a team of medical professionals and researchers, integrating shared patient decision-making at every step of surveillance, diagnosis, and treatment...

BACKGROUND/AIMS: On behalf of the Drug and Therapeutics, and Ethics Committees of the Pediatric Endocrine Society, we sought to update the guidelines published in 2003 on the use of growth hormone (GH). Because idiopathic short stature (ISS) remains a controversial indication, and diagnostic challenges often blur the distinction between ISS, GH deficiency (GHD), and primary IGF-I deficiency (PIGFD), we focused on these three diagnoses, thereby adding recombinant IGF-I therapy to the GH guidelines for the first time...
