Hormones replacement

BACKGROUND: Menopause is associated with elevated cardiovascular risk due to the loss of the cardioprotective effect of oestrogens. Postmenopausal women are often prescribed hormone replacement therapy (HRT) in order to control menopause symptoms and correct hormone imbalances; however, HRT can impact serum lipids' concentrations. At present, data on the effect of the administration of medroxyprogesterone acetate plus conjugated equine oestrogens (MPACEE) on the lipid profile in females are uncertain, as the investigations conducted so far have produced conflicting results...

In females, Alzheimer's disease (AD) incidences increases as compared to males due to estrogen deficiency after menopause. Estrogen therapy is the mainstay therapy for menopause and associated complications. Estrogen, a hormone with multifaceted physiological functions, has been implicated in AD pathophysiology. Estrogen plays a crucial role in amyloid precursor protein (APP) processing and overall neuronal health by regulating various factors such as brain-derived neurotrophic factor (BDNF), intracellular calcium signalling, death domain-associated protein (Daxx) translocation, glutamatergic excitotoxicity, Voltage-Dependent Anion Channel, Insulin-Like Growth Factor 1 Receptor, estrogen-metabolising enzymes and apolipoprotein E (ApoE) protein polymorphisms...

Background Menopause is a physiological state that occurs in all women and refers to the halt of the reproductive phase. The cessation of the reproductive phase occurs through various stages and presents different symptoms such as hot flashes, night sweats, insomnia, anxiety, depression, and irritability. Such pre- and post-menopausal symptoms may affect the daily activities and production capacities of women, impacting the quality of life (QoL) of women. Hormone replacement therapy (HRT) is primarily used to manage menopausal symptoms...

Recently termed pancreoprivic diabetes, type 3c diabetes refers to high blood sugar values secondary to disease of the exocrine pancreas. The disease is most commonly misdiagnosed as type 2 diabetes mellitus (DM) and is overlooked by physicians and the general public. Chronic pancreatitis (CP) accounts for most cases of type 3c diabetes. Diabetic ketoacidosis (DKA) is a rare occurrence in type 3c diabetes as both alpha and beta cell dysfunction occur concurrently. In this case, the major hormones involved in lipolysis and ketone body production would be catecholamines, cortisol, and growth hormone...

The advent of new systemic therapies resulted in a significant decrease in prostate cancer (PCa) death in the past decades. It comes at the cost of an increase in the proportion of men living with long-term treatment-induced hypogonadism. In a population of men with no history of PCa, the testosterone replacement therapy (TRT) proved its ability to both improve erectile function and reduce cardiovascular morbidity, translating into an improved overall survival. Whether TRT is safe and efficient in PCa patients remains an open question...

Uterine fibroids (UFs) are the most common female benign pelvic tumors, affecting over 60% of patients aged 30-44 years. UFs are asymptomatic in a large percentage of cases and may be identified incidentally by a transvaginal ultrasound or a magnetic resonance. However, in around 30% of cases UFs affect quality of life (QoL) and women's health, being abnormal uterine bleeding (AUB) and heavy menstrual bleeding (HMB) the most common complaints, along with iron deficiency (ID) and ID anemia (IDA). Medical treatments used for UFs-related AUB include symptomatic agents, such as nonsteroidal anti-inflammatory drugs and tranexamic acid, and hormonal therapies, including combined oral contraceptives, gonadotropin-releasing hormone (GnRH) agonists or antagonists, levonorgestrel intrauterine systems, selective progesterone receptors modulators and aromatase inhibitors...

BACKGROUND: Menopausal transition is a crucial step in the women's cardiovascular health, and the risk stratification in apparently health post-menopausal females has been rarely assessed. Heart ultrasonography, unusually performed in such subjects, would be able to detect initial signs of organ damage. We described the cardiovascular risk profile of non-diabetic post-menopausal women, evaluating how easily computed, biochemistry-derived scores were related to ultrasonographic measures of target organ damage...

KEY CLINICAL MESSAGE: Hypophyseal dysfunction may be overlooked by the currently generally accepted laboratory routine for the differential diagnosis in patients suffering from symptoms of depression or dementia. ABSTRACT: Hypothyroidism is an important cause of depression and potentially reversible cognitive impairment. Whereas the determination of the plasma concentration of thyrotropin (TSH) is generally considered part of the laboratory screening tests for dementia, the measurement of total or free triiodothyronine (T3, FT3), thyroxine (T4, FT4) and cortisol in plasma does not belong to the routine diagnostic workup in patients with depression or suspected dementia...

Hypoparathyroidism, a deficiency of parathyroid hormone (PTH), results in hypocalcemia, hyperphosphatemia, and hypercalciuria. The disease is poorly controlled by calcium and vitamin D supplements or native PTH(1-84) replacement therapy. A version of PTH is being developed using D-VITylation technology, whereby vitamin D is conjugated to a therapeutic peptide, which confers a long plasma half-life by virtue of binding to the abundant vitamin D binding protein (DBP). D-VITylation of PTH caused no reduction in activity at the PTHR1 receptor, and resulted in a plasma elimination half-life of 7-15 h in rats and 24-32 h in cynomolgus monkeys...

Herein, we report a rare case of invasive nasopharyngeal carcinoma with extension to the pituitary gland misdiagnosed as a pituitary macroadenoma. A 50-year-old woman was referred to our department with a diagnosis of pituitary macroadenoma. She presented with headache, visual disturbances, weakness, nausea, vomiting, and hypoglycemia. Polyuria was not reported. On pituitary magnetic resonance imaging, a large mass was observed to extend from the sella turcica to the sphenoid sinus, optic chiasm, and nasopharynx, leading to the initial diagnosis of an invasive pituitary macroadenoma...

OBJECTIVES: Genetic factors are a major cause of osteoporosis. The present study evaluated the association of the apolipoprotein E (ApoE) genotype with bone mineral density (BMD) and its response to menopausal hormone therapy (MHT) in postmenopausal Korean women. METHODS: This retrospective cohort study included 172 postmenopausal women with no endocrine diseases, medications, or lifestyles that would affect bone metabolism and who were continuously treated with MHT for at least 2 years...

Insects have about 50 neuropeptide genes and about 70 genes, coding for neuropeptide G protein-coupled receptors (GPCRs). An important, but small family of evolutionarily related insect neuropeptides consists of adipokinetic hormone (AKH), corazonin, and AKH/corazonin-related peptide (ACP). Normally, insects have one specific GPCR for each of these neuropeptides. The tick Ixodes scapularis is not an insect, but belongs to the subphylum Chelicerata, which comprises ticks, scorpions, mites, spiders, and horseshoe crabs...

Kidney transplantation provides the best form of kidney replacement therapy with improvement in quality of life and longevity. However, disparity exists in its availability, utilisation and outcomes, not only due to donor availability or financial constraints but also arising from the influence of biological sex and its sociocultural attribute i.e., Gender. Women make up the majority of kidney donors but are less likely to be counselled regarding transpantation, be waitlisted or receive living/deceased donor kidney...

Dental resin systems, used for artificial replacement of teeth and their surrounding structures, have gained popularity due to the Food and Drug Administration's (FDA) recommendation to reduce dental amalgam use in high-risk populations and medical circumstances. Bisphenol A (BPA), an endocrine-disrupting chemical, is an essential monomer within dental resin in the form of various analogues and derivatives. Leaching of monomers from resins results in toxicity, affecting hormone metabolism and causing long-term health risks...

BACKGROUND: Immune checkpoint inhibitors (ICPis) induce autoimmune diseases, including autoimmune polyendocrine syndrome type 2 (APS-2), which is defined as a combination of at least two of the following endocrinopathies: autoimmune thyroid disease, type 1 diabetes, and Addison's disease. Cases with the full triad are rare. We present a case of an elderly woman who developed APS-2 with the complete triad shortly after starting anti-programmed cell death 1 (anti-PD1) treatment and review the related literature...

Turner syndrome (TS) is a sex chromosome abnormality characterized by short stature and primary hypogonadism with increased risk for cardiovascular disease, osteopenia, metabolic syndrome, diabetes mellitus, abnormal liver enzymes, and impairment of nonverbal learning skills. Gender-diverse youth include youth who have a gender identity that is different from their sex assigned at birth. They have an increased risk of suicidality, which is decreased in those who receive gender-affirming care. There have been no prior reports on the association or management of gender-diverse youth with TS...

BACKGROUND: Infective endocarditis rarely results in mitral stenosis. This report presents a case of prosthetic valve infective endocarditis caused by Cutibacterium acnes infection, which resulted in mitral stenosis and was difficult to diagnose. CASE SUMMARY: A 78-year-old Japanese man underwent aortic and mitral bioprosthetic valve replacement six years prior to the initiation of hormone therapy for prostate cancer. Three weeks after hormone therapy initiation, the patient developed exertional dyspnoea that progressively worsened and ultimately led to orthopnoea...

Low back pain derived from intervertebral disc (IVD) degeneration is a debilitating spinal condition that, despite its prevalence, does not have any intermediary guidelines for pharmacological treatment between palliative care and invasive surgery. The development of treatments for the IVD is complicated by the variety of resident cell types needed to maintain the regionally distinct structural properties of the IVD that permit the safe, complex motions of the spine. Osteoporosis of the spine increases the risk of vertebral bone fracture that can increase the incidence of back pain...
