Endothelin (ET)-1-mediated vasoconstrictor tone is elevated in overweight and obese adults, contributing to vasomotor dysfunction and increased cardiovascular disease risk. While the effects of habitual aerobic exercise on endothelium-dependent vasodilation in overweight/obese adults has been studied, little is known regarding ET-1 vasoconstriction. Accordingly, the aims of the present study were to determine: (1) if regular aerobic exercise training reduces ET-1-mediated vasoconstrictor tone in overweight and obese adults; and, if so (2) whether the reduction in ET-1 vasoconstriction contributes to exercise-induced improvement in endothelium-dependent vasodilation in this population...

Carcinoid syndrome is the constellation of symptoms mediated by humoral factors produced by some carcinoid tumors. It consists primarily of vasomotor symptoms, gastrointestinal hypermotility, hypotension, and bronchospasm, due to the production and release of vasoactive substances. Carcinoid heart disease occurs in more than 50% of patients with carcinoid syndrome; in some cases, it represents the initial manifestation of the disease. We report the case of a 75-year-old woman with a metastatic neuroendocrine tumor admitted to the emergency room for fatigue and heart failure...

Heather D Hirsch, Elim Shih, Holly L Thacker
Estrogen receptor agonist-antagonists (ERAAs) selectively inhibit or stimulate estrogen-like action in targeted tissues. This review summarizes how ERAAs can be used in combination with an estrogen or alone to treat menopausal symptoms (vasomotor symptoms, genitourinary syndrome of menopause), breast cancer or the risk of breast cancer, osteopenia, osteoporosis, and other female midlife concerns.

[Purpose] Competitive sport places strict demands on the cardiovascular systems of veteran trail runners. Our research objective was to evaluate the dynamics of microcirculation parameters of veteran runners in hypoxic and mid-altitude conditions. [Subjects and Methods] Seven male runners from Russia and Italy between the ages of 50 and 60 years were examined whilst competing at mid-altitude (1,500-2,000 m above sea level). The same runners were examined in a simulated mid-altitude hypoxic environment, which was a hypoxic chamber with 16% oxygen concentration, for 720 minutes...

OBJECTIVE: Women with gynecologic malignancies will be cured or may become long-term survivors. Management of menopausal symptoms is important in addressing their quality of life. We review the benefit and safety of hormone therapy use in these patients. METHODS: MEDLINE was searched for studies on menopause management published in English through December of 2016. RESULTS: Available data suggest that short-term use of hormone therapy in gynecologic cancer patients who do not have an estrogen-dependent malignancy do not adversely impact oncologic outcome and results in improvement of menopausal vasomotor and genitourinary symptoms...

BACKGROUND: Early and late dumping are complications of gastric bypass surgery. Early dumping occurs within an hour after eating, when the emptying of food into the small intestine triggers rapid fluid shifts into the intestinal lumen and the release of gastrointestinal hormones, resulting in gastrointestinal and vasomotor symptoms. Late dumping occurs between 1 and 3 hours after carbohydrate ingestion and is caused by an exaggerated insulin release, resulting in hypoglycemia. Almost no data are currently available on the prevalence of early and late dumping or their impact on health-related quality of life (QoL)...

BACKGROUND: Vasomotor symptoms are the most commonly reported menopausal symptoms. Hormone therapy has been widely used to relieve postmenopausal symptoms. With studies suggesting an increased risk of cardiovascular events and breast cancer with oral hormone therapy use, there has been reluctance to use it. The transdermal estrogen patch provides relief from menopausal symptoms. However, there are limited data on mortality and cardiovascular outcomes, while on the transdermal estrogen patch...

Chronic or episodic severe itch is recurrent in atopic dermatitis (AD). Non-histaminergic neuronal itch pathways are suggested to dominate in AD itch, contributing to an "itch-scratch-itch cycle" that prolongs and worsens itch, pain, and skin lesions. We hypothesized that non-histaminergic neuronal sensitization contributes to itch in AD. Hence, we compared sensitivity to thermal, mechanical, and chemical pruritic stimuli in AD patients and controls. The study comprised 25 AD patients with chronic itch and 25 healthy controls...

BACKGROUND: Migraine is a common and disabling neurological disorder. Studies attempting to determine a relationship between migraine and the autonomic nervous system (ANS) have been inconclusive. Moreover, pediatric studies are extremely limited. Therefore, the present study investigated interictal ANS function in adolescent migraineurs. METHODS: We studied 21 patients with migraine and 26 healthy controls. Beat-to-beat blood pressure (BP) and heart rate (HR) were noninvasively and continuously measured in the supine and standing positions...

Background Reversible cerebral vasoconstriction syndrome (RCVS) is an important differential diagnosis of singular or recurrent thunderclap headache. Prognosis is generally good, however complications of the transient segmental vasospasms of cerebral arteries such as stroke, subarachnoidal hemorrhage and brain edema may worsen the clinical outcome. Although the exact pathomechanism is still unclear, various vasoactive substances and conditions (e.g. post partum) have been identified as triggering RCVS. Cases We report on the clinical course and management of two cases of typical RCVS that were associated with two different precipitants previously not described: A gastrointestinal infection and isoflavones, which are phytoestrogens used for menopausal vasomotor symptoms...

OBJECTIVE: In studies of the menopausal therapy, conjugated estrogens/bazedoxifene, breast pain and vaginal bleeding rates were comparable to placebo and lower than conjugated estrogens/medroxyprogesterone acetate (MPA). This post hoc analysis determined median time to occurrence of these events. METHODS: Participants in phase 3 conjugated estrogens/bazedoxifene trials recorded breast pain and vaginal bleeding in daily diaries. Median time to first incident was determined in women taking conjugated estrogens 0...

Impaired niacin sensitivity (NS) is one of the most replicated findings in untreated schizophrenia, and reflects a disturbance of prostaglandin-mediated pathways in association with deregulated arachidonic acid metabolism, pro-inflammatory activation, and vasomotor function. In ultra-high risk individuals (UHR) increased NS was reported recently, pointing towards dynamic alterations of the underlying pathomechanisms in the period preceding psychosis. However, these characteristics are still unresolved in the diverse UHR groups...

The purpose of this concept study was to investigate the possibility of automatic mean arterial pressure (MAP) regulation in a porcine heart-beating brain death (BD) model. Hemodynamic stability of BD donors is necessary for maintaining acceptable quality of donated organs for transplantation. Manual stabilization is challenging, due to the lack of vasomotor function in BD donors. Closed-loop stabilization therefore has the potential of increasing availability of acceptable donor organs, and serves to indicate feasibility within less demanding patient groups...

Activation of PI3K/Akt signaling, leading to upregulation of nitric oxide synthase II (NOS II)/peroxynitrite cascade in the rostral ventrolateral medulla (RVLM), the brain stem site that maintains blood pressure and sympathetic vasomotor tone, underpins cardiovascular depression induced by the organophosphate pesticide mevinphos. By exhibiting dual-specificity protein- and lipid-phosphatase activity, phosphatase and tensin homolog (PTEN) directly antagonizes the PI3K/Akt signaling by dephosphorylation of phosphatidylinositol-3,4,5-trisphosphate, the lipid product of PI3K...

Piglets are often used as experimental models for studying cerebrovascular responses in newborn infants. However, the mechanical characteristics of piglets' middle cerebral arteries (MCA) are not well characterized. Additionally, the vessels' response to dopamine, the most commonly used vasopressor in newborns, is not characterized in piglets' MCA. Finally, the influence of preterm birth on the dopamine response is not known. The aim of this current was to compare by wire myography the active and passive mechanical characteristics and dopamine concentration-response relations of MCAs isolated from preterm and term newborn piglets...

Rare neuroendocrine tumours (NETs) that most commonly arise in the gastrointestinal tract can lead to carcinoid syndrome and carcinoid heart disease. Patients with carcinoid syndrome present with vasomotor changes, hypermotility of the gastrointestinal system, hypotension and bronchospasm. Medical therapy for carcinoid syndrome, typically with somatostatin analogues, can help control symptoms, inhibit tumour progression and prolong survival. Carcinoid heart disease occurs in more than 50% of these patients and is the initial presentation of carcinoid syndrome in up to 20% of patients...

BACKGROUND: Natural estrogen decline leads to vasomotor symptoms (VMS). Hormone therapy alleviates symptoms but increases cancer risk. Effective treatments against VMS with minimal cancer risks are needed. We investigate the effects of a highly bioavailable aglycone rich Red Clover isoflavone treatment to alleviate existing menopausal VMS, assessed for the first time by 24hour ambulatory skin conductance (SC). METHODS AND RESULTS: We conducted a parallel, double blind, randomised control trial of 62 peri-menopausal women aged 40-65, reporting ≥ 5 hot flushes/day and follicle stimulating hormone ≥35 IU/L...

In vertebrates, melatonin is primarily secreted from the pineal gland but it affects various biological processes including the sleep-wake cycle, vasomotor control, immune system and bone homeostasis. Melatonin has been known to promote osteoblast differentiation and bone maturation, but a direct role of melatonin on osteoclast differentiation is still elusive. The present study investigated the effect of melatonin on the differentiation of macrophages to osteoclasts. The presence of melatonin significantly reduced receptor activator of nuclear factor κB ligand (RANKL)-induced osteoclastogenesis and the siRNA-mediated knockdown of the melatonin receptor failed to overcome the anti-osteoclastogenic effect of melatonin...
