Tamoxifen has played a vital role in endocrine therapy for the treatment of estrogen receptor-positive breast cancer. We examined the effect of tamoxifen in patients with a thin endometrium in frozen-thawed embryo transfer (FET) cycles and compared the improvement in endometrial thickness (EMT) and pregnancy outcomes stratified by different etiologies of thin endometrium. A total of 226 women were recruited for a new tamoxifen protocol; all had an EMT of less than 7.5 mm in previous cycles, including natural cycle (NC), hormone replacement treatment (HRT), and ovulation induction (OI) cycles...

Captive flatfishes, such as the Senegalese sole, typically produce very low volumes of sperm. This situation is particularly prevalent in the first generation (F1) of reared sole males, which limits the development of artificial fertilization methods and the implementation of selective breeding programs. In this study, we investigated whether combined treatments with homologous recombinant follicle-stimulating (rFsh) and luteinizing (rLh) hormones, produced in a mammalian host system, could stimulate spermatogenesis and enhance sperm production in Senegalese sole F1 males...

BACKGROUND: Suboptimal thyroid hormone therapy including under-replacement and over-replacement is common amongst patients with hypothyroidism. This is a significant health concern as affected patients are at risk of adverse cardiovascular or metabolic consequences. Despite a growing body of evidence on the effects of various factors on thyroid hormone replacement, a systematic appraisal of the evidence is lacking. This review aims to appraise and quantify the extent to which clinical, behavioural and pharmacogenomic factors affect levothyroxine therapy in patients with primary hypothyroidism...

Osteoporosis, a bone disease resulting in loss of bone density and microstructure quality, is often associated with fragility fractures, and the latter imposes a great burden on the patient and society. Although there are several different treatments available for osteoporosis such as hormone replacement therapy, bisphosphonates, Denosumab, and parathyroid hormone some concern has been raised regarding the inherent side effects of their long term use. It would be of great relevance to search for alternative natural compounds, which could complementarily overcome the limitations of the currently available therapy...

Context: in 2007, a large retrospective case-control study provided evidence that adjuvant mitotane prolongs recurrence-free survival (RFS) in patients with radically resected adrenocortical carcinoma (ACC). Objective and design: We aimed to confirm the prognostic role of adjuvant mitotane in the same series after 9 additional years of follow-up. Setting, Patients and Interventions: 162 ACC patients included in the previous study, who did not recur or die after a landmark period of 3 months, were considered...

FGF21 is a natural hormone that modulates glucose, lipid, and energy metabolism. Previously, we engineered an Fc fusion FGF21 variant with two mutations, Fc-FGF21(RG), to extend the half-life and reduce aggregation and in vivo degradation of FGF21. We now describe a new variant developed to reduce the extreme C-terminal degradation and improve the binding affinity to β-Klotho. We demonstrate, by introducing one additional mutation located at the C-terminus of FGF21 (A180E) that the new molecule, Fc-FGF21(RGE), has gained many improved attributes...

Context • Psychoneurological symptoms are present in nearly all women in the perimenopausal period. Key elements of care in the period may include hormone replacement therapy (HRT). Alternatively, phytoestrogens, antidepressant pharmacotherapy, or a combination of hormonal and antidepressant therapies may be recommended. Objective • The study intended to verify whether women who are menopausal believe that a reduction in their symptoms of anxiety and depression depends on the type of pharmacotherapy used...

Progesterone (PG), a natural female sex hormone is used clinically in menopausal hormone replacement therapy and to control reproductive functions. Its very limited aqueous solubility of 7 µg/ml results in reduced oral bioavailability and low patient compliance when administered in high doses. The aim of this study was to enhance PG aqueous solubility and vaginal delivery using solid dispersion, inclusion complex and micellar solubilization techniques. PG solid dispersions and inclusion complexes were prepared by solvent evaporation method using different polymers, such as cyclodextrins, polyvinyl pyrrolidone (PVP), poly (ethylene glycol) 6000, Pluronic® F-127 and Pluronic® F-68...

Cardiovascular disease (CVD) is one of the leading causes of mortality in developed countries. The incidence of CVD is sexually dimorphic, and research has focused on the contribution of sex steroids to the development and progression of the cardiometabolic syndrome, which is defined as a clustering of interrelated risk factors that promote the development of atherosclerosis (which can lead to CVD) and type 2 diabetes mellitus. Data are inconclusive as to how sex steroids and their respective receptors increase or suppress the risk of developing the cardiometabolic syndrome and thus CVD...

Extended adjuvant (5-10 years) therapy targeted to the estrogen receptor (ER) has significantly decreased mortality from breast cancer (BC). Areas covered: Translational research advanced clinical testing of extended adjuvant therapy with tamoxifen or aromatase inhibitors (AIs). Short term therapy or non-compliance increase recurrence, but surprisingly recurrence and death does not increase dramatically after 5 years of adjuvant therapy stops. Expert commentary: Compliance ensures optimal benefit from extended antihormone adjuvant therapy...

Primary signet ring cell carcinoma (SRCC) of the prostate is a rare entity, characterised by its aggressive nature and dismal prognosis. We report a case of an advanced SRCC of the prostate presenting as a large pelvic mass with obstructive uropathy and rectal involvement managed by complete androgen blockade. At 24 months follow-up, the patient has no evidence of progression or metastasis. Aggressive management with multimodality approach combining surgery, radiation and hormonal ablation can result in long disease-free survival in some patients, despite the aggressive nature of this disease...

We report the case of a newborn with neonatal hypotonia associated to a micropenis and a bilateral cryptorchidia. The discovery of severe hypoglycemia at 0.22 mmol/L led to further biological investigations that revealed sharply decreased levels of several hypophyseal hormones. Altered corticotropic, somatotropic, thyreotropic, and gonadotropic axes finally suggested congenital hypophyseal insufficiency. This diagnostic was confirmed by a brain MRI (magnectic resonance imaging), which revealed a total interruption of the pituitary stalk...

Breast cancer is second most prevalent cancer in women, and the second only to lung cancer in cancer-related deaths. It is a heterogeneous disease and has several subtypes based on the presence or absence of hormone receptors and/or human epidermal growth factor receptor 2 (HER2). Hormone receptor-positive and HER2-enriched cancers can be targeted using hormone and HER2-targeting therapies such as trastuzumab or lapatinib. However, triple-negative breast cancers (TNBCs) do not express any of the receptors and therefore are resistant to most targeted therapies, and cytotoxic chemotherapies are the only viable option available for the treatment of TNBCs...

OBJECTIVE: Low-grade serous ovarian carcinomas (LGSOCs) are a histological subtype of epithelial ovarian tumors, accounting for fewer than 5% of all cases of ovarian carcinoma. Due to the chemoresistant nature of this subtype a search for more effective systemic therapies is actively ongoing, hormonal therapy showing some degree of activity in this clinical setting. The present study ought to investigate the hormone receptor status of LGSOCs, as a strategy to provide molecular support for patient-tailored hormonal treatments...

Accumulating evidence suggests a close bidirectional communication and regulation between the neuroendocrine and immune systems. Thyroid hormones (THs) can exert responses in various immune cells, e.g., monocytes, macrophages, natural killer cells, and lymphocytes, affecting several inflammation-related processes (such as, chemotaxis, phagocytosis, reactive oxygen species generation, and cytokines production). The interactions between the endocrine and immune systems have been shown to contribute to pathophysiological conditions, including sepsis, inflammation, autoimmune diseases and viral infections...

Systemically administered opioids are among the most powerful analgesics for treating severe pain. Several negative side-effects (respiratory depression, addiction, nausea, confusion) and the risk of opioid-induced hyperalgesia accompany opioid administration. One other side effect is the potential of opioids to suppress the immune response and thereby to increase the vulnerability for infections. Several studies have investigated the link between opioids and immunosuppression in vitro, in vivo as well as in patients with divergent results: Exogenous opioids such as morphine and fentanyl can impair macrophage and natural killer cell as well as T cell function and weaken the gut barrier in vitro and in animal studies...

Bone is in a constant state of remodeling, a process which was once attributed solely to osteoblasts and osteoclasts. Decades of research has identified many other populations of cells in the bone that participate and mediate skeletal homeostasis. Recently, osteal macrophages emerged as vital participants in skeletal remodeling and osseous repair. The exact mechanistic roles of these tissue-resident macrophages are currently under investigation. Macrophages are highly plastic in response to their micro-environment and are typically classified as being pro- or anti-inflammatory (pro-resolving) in nature...

Prostate cancer is the most common malignancy in males and, despite a marked improvement in diagnostic techniques, a not small percentage of prostate tumours is still diagnosed in advanced stage. It is now clear that prostate cancer passes through distinct phases during its natural history, starting from an initial phase, in which the disease has a locoregional extent, until a very late phase when it becomes refractory to hormone therapy. It is important to distinguish between local disease, in which tumor may be considered localized in the gland and a systemic disease characterized by high tumor burden and/or dissemination of circulating tumour cells...
