Since the first successful human in vitro fertilization (IVF) pregnancy nearly 40 years ago, remarkable progress has been made in assisted reproductive technology (ART). Improvements in oocyte retrieval, embryo culture, genetic screening, and embryo selection have contributed to dramatic improvements in IVF outcomes. A more robust understanding of embryologic development has driven innovation in not only the timing of embryo transfer but also the number of embryos to transfer. Additionally, overcoming the technical hurdle of embryo vitrification has given both physicians and patients several benefits including the flexibility to mitigate effects of superovulation on the endometrium, limit the number of embryos transferred, afforded an opportunity to screen the quality of embryos both by evaluating in vitro development as well as preimplantation genetic testing...

Ovarian hyperstimulation syndrome (OHSS) is one of the most frequent, serious and potentially lethal iatrogenic complications of controlled ovarian stimulation. Despite extensive research, the exact pathogenesis of this syndrome remains less clear, but there appears to be a relationship of increased vascular permeability mediated by HCG and other downstream mediators. Adequate experience with ovulation induction therapy and identifying patients with known risk factors are essential in preventing OHSS. As this is a completely iatrogenic disease numerous strategies have been investigated to help decrease the risk of OHSS and their effects on pregnancy and live birth rate...

The past four decades have delivered many advancements to improve in vitro fertilization (IVF) outcomes. These include a delicate balance of controlled ovarian hyperstimulation (COH) without causing ovarian hyperstimulation syndrome (OHSS), a safe oocyte retrieval, fertilization and embryo culture, endometrial growth and receptivity to promote implantation, and luteal support to maintain the pregnancy. Contemporary IVF practice includes both the classic COH protocols as well as protocols for poor responders and those for specific patient populations...

Prevention of fertility loss due to cancer treatment as well as non-malignant causes has gained importance during the last decades. Clinically applied modalities for fertility preservation in cancer patients include cryopreservation of oocytes and embryos, the application of GnRH agonists, ovarian tissue banking, and cryopreservation of ejaculated or surgically extracted sperm. In addition, several new possibilities to restore fertility are currently being investigated, such as the establishment of in vitro culture systems for gonadal tissue, the development of artificial gonads, and the application of germline stem cells...

BACKGROUND: Kallistatin is a secreted protein that acts as a tissue kallikrein inhibitor. It has antiinflammatory, antioxidant and vasoprotective properties. Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disease associated with low-grade chronic inflammation and multiple risk factors for cardiovascular diseases. The aims of this study were to ascertain whether circulating kallistatin levels are altered in women with PCOS, and whether there is an association between kallistatin and carotid intima media thickness (cIMT) as well as inflammatory markers high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α (TNF-α)...

INTRODUCTION: Results of the effects of Roux-en-Y gastric bypass (GB) and sleeve gastrectomy (SG) on triglyceride and high-density lipoprotein (HDL) cholesterol levels are controversial. Moreover, previous meta-analyses focused on global dyslipidaemia remission, but did not include the separate remission rates of the different lipid fractions. Hence, the aim of the present meta-analysis was to compare the outcomes (concentration change and remission rates) of GB and SG on diverse lipid disorders one year post-bariatric surgery (BS)...

Thyroid hormones are crucial for hepatic lipid and glucose metabolism. Nonalcoholic fatty liver disease (NAFLD), a very common and potentially serious disease of modern society, shares common clinical features with hypothyroidism, such as obesity, insulin resistance and dyslipidemia. Furthermore, in certain studies, increased prevalence of hypothyroidism was observed in patients with NAFLD. However, whether there is a linear relationship between thyroid hormone levels and NAFLD incidence and severity, including values within or in proximity to the reference range remains a contradictory subject in the literature...

CONTEXT: For decades gross-total resection was the preferred treatment option in childhood-onset craniopharyngioma, assuming that radical strategies at the time of initial diagnosis and treatment would result in cure. Recent reports on long-term prognosis, novel treatment approaches, and molecular genetics provide new insights into more risk-adapted treatment strategies in order to prevent sequelae such as hypothalamic syndrome. EVIDENCE ACQUISITION: A search for original articles published between 2000 and 2016 was performed in PubMed, Science Citation Index Expanded, EMBASE and Scopus...

BACKGROUND: The transition for type 1 diabetes patients from paediatric to adult diabetology care is challenging process for both medical team and patients. Adult diabetology usually insists on stricter goals and focuses on increased empowerment and self-care. We set to find a more practical and effective way to determine patient knowledge and skills during the transition. The aim of the study was to identify screening questions which best represent knowledge in management of type 1 diabetes and to explore the differences in the effect of a structured educational program for type 1 diabetes patient diagnosed in childhood versus adulthood...

BACKGROUND: Multicellular spheroids represent an interesting experimental model with promising applications in the pre-clinical studies on anticancer drugs. We recently demonstrated that thyroid spheroids recapitulate the features of the original tissues, in either the differentiated and "stem-like" components. Here we were aimed to characterize thyroid spheroids and to investigate in vivo the proangiogenic potential of patient-derived xenografts (PDX) of spheroids obtained from papillary thyroid cancer (PTC) and the matched normal tissues...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive aged women. PCOS incorporates not only symptoms related to the reproductive system but also a clustering of systemic metabolic abnormalities that are linked with increased risk for cardiovascular disease (CVD). More specifically, metabolic aberrations such as impaired glucose and lipid metabolism, accompanied by increased low-grade inflammation as well as elevated coagulation factors appear to contribute to the increased cardiovascular risk...

BACKGROUND Receptor activator of nuclear factor-kappaB ligand (RANKL) and osteoprotegerin (OPN) are soluble members of the tumor necrosis factor superfamily. Growing evidence suggest that there is link between inflammation, insulin resistance and OPG, sRANKL. We aimed to ascertain whether OPG and sRANKL levels are altered in prediabetic subjects and there is association between OPG, sRANKL and metabolic parameters. MATERIAL AND METHODS: 40 prediabetic subjects and 40 age- and BMI-matched controls were recruited for this cross-sectional study...

Non-alcoholic fatty liver disease (NAFLD) is more common in men than in women. Thus, it has been suggested that sex steroids do have a role in the development of NAFLD. The aim of the current paper is to illustrate the association between NAFLD and hypogonadism, by reviewing data derived from both human and animal studies. The prevalence of NAFLD is high in men with hypogonadism, including those with idiopathic hypogonadotropic hypogonadism (IHH), as well as in women in post-menopause, those under estrogen receptor antagonist treatment or women with Turner syndrome...

Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome and has a complex pathophysiology with multiple pathways of development and progression implicated. Intestinal hormones regulate multiple biological functions and may play a role in the pathogenesis of non alcoholic fatty liver disease (NAFLD) by affecting food intake, body weight and insulin resistance. Bacterial products can affect the secretion of these hormones and thus have an effect on metabolism. Gut microbiota are normally involved in the intestinal energy harvest and their role has been increasingly been implicated in the pathogenesis of obesity and NAFLD...

Obesity and insulin resistance (IR) are frequently present in patients with polycystic ovary syndrome (PCOS). Both disorders also play an important role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). Accordingly, NAFLD is frequently present in patients with PCOS. In the present review, we summarize the findings of the major studies that assessed the prevalence of NAFLD in patients with PCOS. The factors driving the increased frequency of NAFLD in patients with PCOS are also analyzed. Finally, we discuss the management options of NAFLD in patients with PCOS...

The association of obesity with non-alcoholic fatty liver disease (NAFLD) has been established. Obesity has been linked not only to initial stages of the disease, i.e., simple steatosis (SS), but also to its severity. From an epidemiologic point of view, both diseases has an increasing prevalence worldwide. From a pathogenetic point of view, obesity and its associate IR contribute to the initial fat accumulation in the hepatocyte (SS), but also to the progression of SS to nonalcoholic steatohepatitis (NASH), NASH-related cirrhosis and hepatocellular carcinoma (HCC)...
