We have previously demonstrated the cardioprotective effects of ovarian hormones against adverse ventricular remodeling imposed by chronic volume overload. Here, we assess the estrogen receptor dependence of this cardioprotection. Four groups of female rats were studied: sham-operated (SHAM), volume overloaded (ACF), SHAM treated with estrogen receptor antagonist, ICI 182,780 (SHAM+ICI), and ACF treated with ICI. Cardiac function was assessed temporally using echocardiogram and tissue samples were collected at 5 days and 6 weeks post-surgery...

Lipedema, or adiposis dolorosa, is a common adipose tissue disorder that is believed to affect nearly 11% of adult women worldwide. It is characterized most commonly by disproportionate adipocyte hypertrophy of the lower extremities, significant tenderness to palpation, and a failure to respond to extreme weight loss modalities. Women with lipedema report a rapid growth of the lipedema subcutaneous adipose tissue in the setting of stress, surgery, and/or hormonal changes. Women with later stages of lipedema have a classic "column leg" appearance, with masses of nodular fat, easy bruising, and pain...

AIM: Ganglioneuroma (GN) is the most uncommon and the most benign tumor among neuroblastic neoplasms, and in 29.7% of cases it finds in an adrenal gland. Usually asymptomatic, this tumor is detected incidentally in the majority of cases. It is generally challenging to obtain a precise diagnosis of adrenal ganglioneuroma (AGN) before surgery. Misdiagnosis rate of AGN on CT and MRI is 64.7% and clinicians and surgeons are often lacking in knowledge of this rare disease. For this reason, we pointed out the clinical, biochemical, radiologic and pathologic features of AGN in an our experience, with the aim to find out if there are some features able to facilitate a preoperative diagnosis...

BACKGROUND: A harmful effect of stress hormone secretion during surgery is lipolysis and proteolysis to maintain normal blood glucose levels. A well-titrated general anesthetic improves blood glucose control by suppressing secretion of these stress hormones. The aim of this study was to explore the effect of intraoperative glucose infusion on lipolysis and proteolysis in patients undergoing a general anesthetic consisting of sevoflurane and remifentanil during long (>6 hours) major surgery...

BACKGROUND: Surgical stress initiates a series of host hormone, metabolism and immune responses, which predominantly affect the homeostatic mechanism of patients with major surgery. B7-H3 is a co-stimulatory molecule and has been shown to participate in both adaptive and innate immune responses. In this study we evaluated the clinical significance of plasma B7-H3 levels in pediatric patients with different types of operation and degrees of surgical stress. METHODS: A total of 48 children received pediatric general and cardiac surgery were recruited into this study...

INTRODUCTION: Surgical stress response, results in elevated levels of anti-insulin hormones and reduced insulin secretion. This hormonal state may be detrimental for surgical patients due to the presence of insulin resistance and hyperglycemia. Additionally, pre-operative fasting favors this conditions. The aim of this study is to analyze the impact of pre-operative caloric load, with 440kJ from amino acid infusions on the levels of glucose, cortisol and insulin resistance in surgical patients...

Huntington's disease (HD) is a genetic neurological disorder that causes severe and progressive motor, cognitive, psychiatric, and metabolic symptoms. There is a robust, significant elevation in circulating levels of the stress hormone, cortisol, in HD patients; however, the causes and consequences of this elevation are largely uncharacterized. Here, we evaluated whether elevated levels of corticosterone, the rodent homolog of cortisol, contributed to the development of symptomology in transgenic HD mice. Wild-type (WT) and transgenic R6/2 mice were given either 1) adrenalectomy with WT-level corticosterone replacement (10ng/ml), 2) adrenalectomy with high HD-level corticosterone replacement (60ng/ml), or 3) sham surgery without replacement...

Ghrelin is a gastric hormone that stimulates hunger and worsens glucose metabolism. Circulating ghrelin is decreased after Roux-en-Y gastric bypass (RYGB) surgery; however, the mechanism(s) underlying this change is unknown. We tested the hypothesis that jejunal nutrient exposure plays a significant role in ghrelin suppression after RYGB. Feeding tubes were placed in the stomach or jejunum in 13 obese subjects to simulate pre-RYGB or post-RYGB glucose exposure to the gastrointestinal (GI) tract, respectively, without the confounding effects of caloric restriction, weight loss, and surgical stress...

Non-intubated thoracic surgery entails procedures performed through regional anesthesia method in awake or mildly sedated, spontaneously ventilating patients. This method represents advantages for the cardiovascular system, and reduces the orotracheal trauma, postoperative atelectasis, and pneumonia. It also possibly reduces costs. Other theoretical advantages are: easier acceptance of surgery, attenuated stress hormone and immune response, and possibly a better survival in oncological surgery. We show a 34-year-old woman with sever palmar-axillary hyperhidrosis...
