OBJECTIVE: Increased adipose production of 4-hydroxynonenal (4-HNE), a bioreactive aldehyde, directly correlates with obesity and insulin resistance. The aim of this study was to elucidate the impact of 4-HNE in mediating adipocyte differentiation and function in two metabolically distinct obese groups; the insulin sensitive (IS) and the insulin resistant (IR). METHODS: Subcutaneous (SC) adipose tissues were obtained from eighteen clinically well characterized obese premenopausal women undergoing weight reduction surgery...

Erectile dysfunction (ED) associated with type 2 diabetes mellitus (T2DM) involves dysfunctional nitric oxide (NO) signaling and increased oxidative stress in the penis. However, the mechanisms of endothelial NO synthase (eNOS) and neuronal NO synthase (nNOS) dysregulation, and the sources of oxidative stress, are not well defined, particularly at the human level. The objective of this study was to define whether uncoupled eNOS and nNOS, and NADPH oxidase upregulation, contribute to the pathogenesis of ED in T2DM men...

INTRODUCTION: Cardiopulmonary bypass (CPB) can cause stress response that increases levels of cytokine and catecholamine in plasma, resulting in hyperglycemia. In adults, it has been demonstrated that remifentanil infusion during CPB could prevent increases of cytokine, catecholamine, and blood glucose levels, but such effects of remifentanil in children have not been elucidated. AIM: In this study, we investigated the preventive effects of remifentanil on blood glucose and lactate levels during CPB in children...

OBJECTIVES: Surgical trauma produces metabolic and hormonal responses, which are characterized by insulin resistance. Due to extension of the preoperative fasting period, which increases the magnitude of postoperative insulin resistance, preoperative oral carbohydrates (POC) have been developed. PATIENTS AND METHODS: This prospective, randomized, controlled study was performed on 43 ASA I-II patients undergoing elective microsurgical lumbar discectomy. The intervention group received oral carbohydrate solution 800mL the night before and 400mL 2h prior to operation...

Minimally invasive surgery seems to reduce hormonal stress response to surgery, but has not previously been examined in major abdominal vascular surgery. Aortic cross-clamping time and operation time is known to be longer in the totally laparoscopic aortobifemoral bypass (LABF) as compared to open aortobifemoral bypass (OABF). The main objective of our study was to measure the hormonal stress response during surgery and aortic cross-clamping in patients undergoing a totally laparoscopic versus an open aortobifemoral bypass...

BACKGROUND: Results of anterior cruciate ligament (ACL) reconstruction are traditionally excellent in younger and nonarthritic patients. During the past few decades, people older than 60 years have become more active than ever, with more demanding physical lifestyles. An increase also has been noted in active patients with diagnosed ACL injuries. More patients are requesting treatment for ACL deficiency in hopes of returning to preinjury levels of activity. PURPOSE: The aims of this study were to evaluate the results of ACL reconstruction in patients older than 60 years in terms of functional recovery, return to sports, and postoperative incidence of osteoarthritis and to compare their results with published results of different age groups...

Chemotherapy-associated steatohepatitis is attracting increasing attention because it heralds an increased risk of morbidity and mortality in patients undergoing surgery because of liver metastases. The aim of this study was to develop in vitro and in vivo models to analyze the pathogenesis of 5-fluorouracil (5-FU)-induced steatohepatitis.Therefore, primary human hepatocytes and HepG2 hepatoma cells were incubated with 5-FU at non-toxic concentrations up to 24 h. Furthermore, hepatic tissue of C57BL/6N mice was analyzed 24 h after application of a single 5-FU dose (200 mg/kg body weight)...

(1) Background: Hepatocellular carcinoma (HCC) is the second leading cause of cancer deaths worldwide, and surgical resection is the main treatment for HCC. To date, no published study has examined the status of coenzyme Q10 in patients with HCC after surgery. Thus, the purpose of this study was to investigate the correlations between the level of coenzyme Q10, oxidative stress, and inflammation in patients with HCC after surgery; (2) Methods: 71 primary HCC patients were recruited. Levels of coenzyme Q10, vitamin E, oxidative stress (malondialdehyde), antioxidant enzymes activity (superoxidase dismutase, catalase, and glutathione peroxidase), and inflammatory markers (high sensitivity C-reactive protein; tumor necrosis factor-α; and interleukin-6) were measured; (3) Results: Patients with HCC had a significantly lower levels of coenzyme Q10 (p = 0...

PURPOSE: To determine if isoflurane anesthesia without surgery causes systemic inflammation in children. Inflammation is targeted as responsible for the development of many neurologic pathologies. The effect will be evaluated by measuring serum cytokine levels before and after isoflurane anesthesia. The possible neurotoxic effect of anesthetic agents is a concern in pediatric anesthesia. Questions remain as to the true effects of anesthesia alone on systemic inflammation. The current study assesses systemic inflammatory response to general anesthesia in children not exposed to surgical stress...

ERAS program applied to colorectal laparoscopic surgery is well known to reduce hospitalization improving short terms outcomes and minimizing the Surgical Stress Response. However its effectiveness in elderly population is yet to be demonstrated. The primary aim of this study is to compare the level of immune and nutritional serum indexes across surgery in patients aged over 70 years old undergoing elective colorectal laparoscopic surgery within an ERAS protocol or according to a Standard program. 83 patients undergoing colorectal laparoscopic surgery were enrolled and randomized in two groups (ERAS Group 40, Standard Group 43) within a larger randomized trial on a general population...

In this study, we tested the hypothesis that chronic stress has cumulative effects over time on heart rate variability (HRV) and physiological responses in a rodent model of chronic mild stress. Rats were exposed to either short-term (2weeks) or long-term (4weeks) stress, followed by a 1-week recovery period. Controls were normally housed rats that did not undergo the stress procedure. For electrocardiogram recordings, transmitters were implanted in all rats 10days before the onset of the experiment to allow recovery from surgery...

BACKGROUND: Sirtuin 1 (SIRT1) appears to play a protective role against endothelial dysfunction and oxidative stress. Instead, matrix metalloproteinase 2 (MMP2) is involved in acute coronary events, by promoting tissue remodeling. This study sought to determine the clinical value of a prognostic index arising from the combination of these two biomarkers for myocardial infarction (MI) in patients with advanced coronary artery disease. METHODS: Eighty-one patients with advanced coronary artery disease planned for open heart surgery were prospectively enrolled...

BACKGROUND: The birth of a child with a disorder of sex development (DSD) and atypical genitalia can be traumatizing and isolating for families. Parents of children with DSD are at risk for increased levels of psychological distress, including depression, anxiety, illness uncertainty (IU), post-traumatic stress symptoms (PTSS), and impairments in quality of life (QOL). Our previous report indicated that although the majority of parents of children with atypical genitalia were coping well prior to the child's genitoplasty, approximately 25% of them reported experiencing some type of psychological distress...

This study quantifies thrombogenic potential (TP) of a wide range of left ventricular assist device (LVAD) outflow graft anastomosis angles through state-of-the-art techniques: 3D imaged-based patient-specific models created via virtual surgery and unsteady computational fluid dynamics with Lagrangian particle tracking. This study aims at clarifying the influence of a single parameter (outflow graft angle) on the thrombogenesis associated with flow patterns in the aortic root after LVAD implantation. This is an important and poorly-understood aspect of LVAD therapy, because several studies have shown strong inter and intrapatient thrombogenic variability and current LVAD implantation strategies do not incorporate outflow graft angle optimization...

: The transmembrane 6 superfamily member 2 (TM6SF2) loss-of-function variant, rs58542926, is a genetic risk factor for nonalcoholic fatty liver disease and progression to fibrosis, but is paradoxically associated with lower levels of hepatic-derived triglyceride-rich lipoproteins (TRLs). TM6SF2 is expressed predominately in liver and small intestine, sites for triglyceride rich lipoprotein biogenesis and export. In light of this, we hypothesized that TM6SF2 may exhibit analogous effects on both liver and intestine lipid homeostasis...

OBJECTIVE Over the past decade, Enhancing Recovery After Surgery (ERAS) programs have been implemented throughout the world across multiple surgical disciplines. However, to date no spinal surgery equivalent has been described. In this report the authors review the development and implementation of a "fast track" surgical approach for lumbar fusion. METHODS The first 42 consecutive cases in which patients were treated with the new surgical procedure were reviewed. A combination of endoscopic decompression, expandable cage deployment, and percutaneous screw placement were performed with liposomal bupivacaine anesthesia to allow the surgery to be performed without general endotracheal anesthesia...
