Insulin Resistance in Type 1 Diabetes Mellitus and Its Association with Patient ’s Micro- and Macrovascular Complications, Sex Hormones, and Other Clinical Data
ConclusionsAccording to stratified eGDR, IR was found for one-third of the current T1D population. Insulin resistant patients more frequently had microvascular complications and CVD events. Lower eGDR, longer diabetes duration, and lower HbA1c significantly increased CVD outcomes risk. IR was related to smoking, obesity, gender, age, and diabetes duration. Moreover, men ’s testosterone had a positive correlation with IR in T1D. Finally, patients with T1D and a positive family history of T2D were not susceptible to weight gain, while MS metabolic phenotype prevalence tended to be higher in obese than in lean patients with...

Aging and the Male Reproductive System.
Authors: Kaufman JM, Lapauw B, Mahmoud A, T'Sjoen G, Huhtaniemi IT Abstract This narrative review presents an overview of present knowledge on fertility and reproductive hormones changes in aging men, the factors driving and modulating these changes, their clinical consequences, and benefits and risks of testosterone (T) therapy. Aging is accompanied by moderate decline of gamete quality and fertility. Population mean levels show mild total T decline, SHBG increase, steeper free T decline, and moderate LH increase with important contribution of comorbidities (e.g. obesity) to these changes. Sexual symptoms and lowe...

Endocrine Disruptors and Health Effects in Africa: A Call for Action
Conclusion: To address the many challenges posed by EDCs, we argue that Africans should take the lead in prioritization and evaluation of environmental hazards, including EDCs. We recommend the institution of education and training programs for chemical users, adoption of the precautionary principle, establishment of biomonitoring programs, and funding of community-based epidemiology and wildlife research programs led and funded by African institutes and private companies. https://doi.org/10.1289/EHP1774 Received: 16 February 2017 Revised: 22 May 2017 Accepted: 24 May 2017 Published: 22 August 2017 Address correspond...

In assessing risk of hormone therapy for menopause, dose — not form — matters
FINDINGSWhen it comes to assessing the risk of estrogen therapy for menopause, how the therapy is delivered — taking a pill versus wearing a patch on one’s skin — doesn’t affect risk or benefit, researchers at UCLA and elsewhere have found. But with the commonly used conjugated equine estrogen, plus progestogen, the dosage does. Higher doses, especially over time, are associated with greater risk of problems, including heart disease and some types of cancer, especially among obese women.BACKGROUNDThe Women ’s Health Initiative established the potential of estrogen therapy to increase or decrease the risk of strok...

Sex Differences in the Impact of Shift Work Schedules on Pathological Outcomes in an Animal Model of Ischemic Stroke.
Abstract Circadian clock desynchronization has been implicated in the pathophysiology of cardiovascular disease and related risk factors (e.g., obesity, diabetes). Thus, we examined the extent to which circadian desynchronization exacerbates ischemic stroke outcomes and whether its detrimental effects on stroke severity and functional impairments are further modified by biological sex. Circadian entrainment of activity rhythms in all male and female rats was observed during exposure to a fixed light:dark (LD) 12:12 cycle but was severely disrupted when this LD cycle was routinely shifted (12hr advance/5d) for ≈ ...

Sex hormones and ischemic stroke: a prospective cohort study and meta-analyses.
CONCLUSIONS: Extreme low endogenous testosterone concentrations were associated with high risk of IS in men, a risk mediated in part by body mass index and hypertension. Whether or not low testosterone is a causal factor for IS or merely a biomarker of poor metabolic health is still not known. PMID: 26509870 [PubMed - as supplied by publisher]

Abstract 1852: Merlin/NF2 is associated with elevated aromatase expression and estrogen formation in human liver tissues and liver cancer cells: An unifying model for hepatocellular carcinoma development and progression
It is recognized that the product of neurofibromatosis type 2 (NF2) tumor suppressor gene, also referred to as Merlin/neurofibromin, is implicated in the homeostatic regulation of the liver stem cell niche through the control of abundance and signaling of epidermal growth factor receptor (EGFR), with a mechanism independent of the Mst/Lats/Yap Hippo pathway [1]. We have previously reported that locally elevated estrogen formation, driven by abnormally high expression and function of the aromatase enzyme, may be implicated in both development and progression of human hepatocellular carcinoma (HCC) through the activation of ...

What have we learned about GPER function in physiology and disease from knockout mice?
Publication date: Available online 16 July 2015 Source:The Journal of Steroid Biochemistry and Molecular Biology Author(s): Eric R. Prossnitz, Helen J. Hathaway Estrogens, predominantly 17β-estradiol, exert diverse effects throughout the body in both normal and patho-physiology, during development and in reproductive, metabolic, endocrine, cardiovascular, nervous, musculoskeletal and immune systems. Estrogen and its receptors also play important roles in carcinogenesis and therapy, particularly for breast cancer. In addition to the classical nuclear estrogen receptors (ERα and ERβ) that traditionally mediate predomi...

A Review of the Relationships between Endogenous Sex Steroids and Incident Ischemic Stroke and Coronary Heart Disease Events.
Authors: Kim C, Cushman M, Kleindorfer D, Safford MM, Redberg RF, Lisabeth L Abstract For decades, it has been recognized that men have a higher age-adjusted risk of ischemic cardiovascular (CVD) events compared to women, thus generating hypotheses that sex steroids contribute to CVD risk. Potential mechanisms include genomic and non-genomic effects of sex steroids as well as mediation through classic CVD risk factors and obesity. However, results from randomized studies suggest that sex steroid supplementation in men and women do not result in improved CVD outcomes and may increase CVD risk. In contrast, prospecti...

Hyperpolarization-activated current-mediated slow afterhyperpolarization in myelinated Ah-type of baroreceptor neurons isolated from adult female rats
Compelling evidence indicates that baroreceptor/baroreflex dysfunction closely impacts on hypertension and CNS disorder, such as stroke . Baroreceptor neurons, with their mechanosensitive terminals and cell bodies located in aortic arch and nodose ganglia, receive the signals regarding blood pressure change and regulate the blood pressure quickly and efficiently through the baroreflex. Mechanosensitive terminals encode the pressure response into repetitive discharge that is received by baroreceptor neurons with various frequencies depending upon the blood pressure. From clinical point of view, nerve degenerative, such as P...
