#1
REVIEW
Ábel Decmann, Pál Perge, Miklós Tóth, Peter Igaz
INTRODUCTION: Adrenal myelolipoma is an invariably benign neoplasm of the adrenal gland that is the second most common primary adrenal incidentaloma following adrenocortical adenomas. It is composed of elements of adipose tissue and extramedullary hematopoiesis. Hypotheses on stem cells and hormonal factors have been formulated regarding its pathogenesis that is still obscure. Despite its benign behavior, adrenal myelolipoma is clinically relevant as it might cause significant difficulties in the differential diagnosis of adrenal tumors...

CONTEXT: Adult body fat is associated with birth anthropometry, suggesting a role for metabolic regulators including vitamin D and the adipokines-adiponectin and irisin-which have been reported to interact but, as yet, data remain controversial. OBJECTIVE: To study (i) the relationship between vitamin D, its binding protein (VDBP) and the adipokines, adiponectin, and irisin in mothers and neonates at birth and (ii) their effects on neonate anthropometric outcomes...

PURPOSE: Temozolomide (TEM) based therapy has been reported being effective in the treatment of metastatic neuroendocrine neoplasms (NEN), with response rates ranging from 30 to 70%. Among patients affected by advanced glioblastoma or melanoma and treated with TEM, loss of tumoral O6-methylguanine DNA methyltransferase (MGMT) is correlated with improved survival. In NEN patients, the role of MGMT deficiency in predicting clinical outcomes of TEM treatment is still under debate. METHODS: In this study we evaluated 95 patients with advanced NENs undergoing treatment with TEM-based therapy...

PURPOSE: The primary aim of this study is to isolate cytokines specific for active Graves' orbitopathy (GO) in the tears of affected patients. The secondary aim is to identify other cytokines of interest and to look at the profile of their levels over time. METHODS: This is a prospective pilot study conducted at the Singapore National Eye Centre. A total of 10 patients with active GO and 10 patients from each of 3 control groups were recruited. The 3 control groups were the following: age-matched normal female patients, patients with GO who were clinically inactive and patients with bilateral viral conjunctivitis...

BACKGROUND AND AIMS: Growth hormone deficiency (GHD) is a condition associated with increased cardiovascular risk and insulin-resistance. Oxidative stress (OS) could be a mechanism underlying both these phenomena. In order to investigate plasma antioxidant defenses in such condition, we evaluated adults with GHD, compared with controls and metabolic syndrome patients (MetS), studying plasma total antioxidant capacity (TAC) and coenzyme Q10 (CoQ10, lipophilic antioxidant) levels, both in its oxidized and reduced forms, correlating this data with metabolic and hormonal pattern...

INTRODUCTION: Steroid myopathy is a well-known sign of endogenous Cushing's syndrome as well as a side effect of glucocorticoid administration. The clinical finding of muscle weakness and the clinical inspection of the muscle size are the most commonly used diagnostic tools, sometimes in combination with needle electromyography, but there are no means to detect the myopathy before the appearance of clinical or electrodiagnostic signs. Until now, no guidelines have been produced for a disease-specific evaluation of muscle impairment in patients with Cushing's syndrome...

PURPOSE: Breast cancer patients (BCP) are at risk of female sexual dysfunction (FSD). Our aim was to clarify the effects of treatment strategies, and steroid hormones levels on FSD. METHODS: We enrolled 136 BCP (46.9 ± 0.8 years), and 122 completed questionnaires. BCP were divided into four groups: 22 women with advanced breast cancer on neoadjuvant therapy (NAT), 48 on adjuvant therapy (AT), 30 taking hormonal therapy (HT) and 22 with metastatic cancer on first line chemotherapy (FLT)...

PURPOSE: High-altitude (HA) environment causes changes in cellular metabolism among unacclimatized humans. Previous studies have revealed that insulin-dependent activation of protein kinase B (Akt) regulates metabolic processes via discrete transcriptional effectors. Moreover, protein arginine methyltransferase (PRMT)1-dependent arginine modification of forkhead box other (FoxO)1 protein interferes with Akt-dependent phosphorylation. The present study was undertaken to test the involvement of PRMT1 on FoxO1 activation during hypobaric hypoxia (HH) exposure in rat model...

PURPOSE: The aim of the study was to assess the usefulness of intraoperative neuromonitoring (IONM) in identifying anatomical variants of the recurrent laryngeal nerve (RLN) during thyroidectomies, with emphasis on the nerve's relationship to the inferior thyroid artery (ITA), Zuckerkandl's tubercle, nonrecurrent laryngeal nerves (NRLNs), and extralaryngeal bifurcation. METHODS: A total of 128 subjects undergoing surgery for thyroid disorders were enrolled in the study, and the course and anatomical variants of RLN were assessed with IONM application...

PURPOSE: Octreotide (OCT) has been successfully used for treatment of acromegaly and neuroendocrine tumors for more than 30 years. However, long-term safety of OCT has not been documented in placebo-controlled setting. This present analysis pooled safety data from two similarly-designed, randomized, and placebo-controlled studies to evaluate long-term safety of long-acting OCT (20, 30 mg); targeted post-hoc analyzes focused on cardiac, hepatic, and renal safety. METHODS: Two studies (NCT00131144, NCT001308450) were conducted in patients with diabetic retinopathy (OCT20 = 191, OCT30 = 348, placebo = 347)...

PURPOSE: There is a paucity of epidemiological information on treatment and imaging of pituitary adenomas in Australia. METHODS: Australian data on pituitary surgery, hospital admissions for pituitary adenomas, and pituitary imaging on patients 15 years and over were obtained from administrative databases between 2000/2001 and 2014/2015. Changes over time and by age and sex were assessed. RESULTS: In 2014/15 there were 37.7 pituitary procedures/million population, corresponding to a 35...

PURPOSE: GLP-1 receptor agonists are antidiabetic drugs currently used in the therapy of type 2 diabetes. Despite several in vitro and in vivo animal studies suggesting a beneficial effect of GLP-1 analogues on bone, in humans their skeletal effects are not clear and clinical studies report conflicting results. METHODS: We differentiated human mesenchymal stromal cells (hMSC) toward the adipogenic and the osteoblastic lineages, analysing the effect of Exendin-4 (EXE) before, during and after specific differentiations...

OBJECTIVE: To evaluate the cut-off value of the ratio of 24 h urinary free cortisol (24 h UFC) levels post-dexamethasone to prior-dexamethasone in dexamethasone suppression test (DST) during the diagnosis of primary pigmented nodular adrenocortical disease in Chinese adrenocorticotropic hormone-independent Cushing syndrome. DESIGN: Retrospective study. PARTICIPANTS: The patients diagnosed with primary pigmented nodular adrenocortical disease (PPNAD, n = 25), bilateral macronodular adrenal hyperplasia (BMAH, n = 27), and adrenocortical adenoma (ADA, n = 84) were admitted to the Peking Union Medical College Hospital from 2001 to 2016...

INTRODUCTION: Non-randomized trials suggest that metformin may reduce TSH levels through unknown mechanisms. OBJECTIVE: To evaluate whether metformin can reduce TSH levels in subjects with subclinical hypothyroidism. PATIENTS AND METHODS: This is a randomized, double-blind, placebo controlled clinical trial with 3 months duration that enrolled 48 individuals, between 18 and 65 years, with subclinical hypothyroidism. The patients were randomized to the use of metformin 850 mg or placebo twice a day for 3 months...

PURPOSE: Insulin-like growth factor 1 (IGF1) controls growth hormone (GH) secretion via a negative feed-back loop that may disclose novel mechanisms possibly useful to control GH hyper-secretion. Our aim was to understand whether PI3K/Akt/mTOR pathway is involved in IGF1 negative feedback on GH secretion. METHODS: Cell viability, GH secretion, Akt, and Erk 1/2 phosphorylation levels in the rat GH3 cell line were assessed under treatment with IGF1 and/or everolimus, an mTOR inhitior...

PURPOSE: The primary objective of the present study was to examine the association between branched chain and aromatic amino acid profiles (BCAA and AAA respectively) and the metabolic syndrome (MS), and to evaluate the clinical utility of these associations in the diagnostic process. METHODS: Two hundred and sixty three healthy men with MS [MS(+): n = 165] and without MS [MS(-): n = 98] were enrolled in the observational study. Anthropometrical, biochemical, and amino acid measurements were performed...
