OBJECTIVE: Anesthetic isoflurane plus surgery has been reported to induce cognitive impairment. The underlying mechanism and targeted intervention remain largely to be determined. Ginsenoside Rb1 was reported to be neuroprotective. We therefore set out to determine whether ginsenoside Rb1 can attenuate isoflurane/surgery-induced cognitive dysfunction via inhibiting neuroinflammation and oxidative stress. METHODS: Five-months-old C57BL/6J female mice were treated with 1...

INTRODUCTION AND HYPOTHESIS: Increased incidences of complications related to the use of mid-urethral slings (MUS) for the treatment of stress urinary incontinence resulted in both the Food and Drug Administration (FDA) and Health Canada issuing advisories in 2008 and 2010 respectively. The purpose of this study was to assess the effect these advisories had on the number of surgeons performing MUS surgery and post-surgical complications in Calgary, Canada. METHODS: In this study, we conducted a retrospective analysis of administrative data between 2006 and 2011...

RATIONALE: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzyme defect, resulting in deficits in nicotinamide adenine dinucleotide phosphate production, an important intracellular antioxidant enzyme. G6PD-deficient subjects present with a susceptibility of erythrocytes to oxidative stress and hemolysis, and should avoid drugs or stressors that have oxidative actions. Dexmedetomidine is an anesthetic agent with antioxidant actions. PATIENT CONCERNS AND DIAGNOSES: A 5-year-old boy with G6PD deficiency...

Cochlear implantation (CI) is increasingly being used in the auditory rehabilitation of deaf patients. Here, we investigated whether the auditory rehabilitation can be influenced by the psychological burden caused by mental conditions. Our sample included 47 patients who underwent implantation. All patients were monitored before and 6 months after CI. Auditory performance was assessed using the Oldenburg Inventory (OI) and Freiburg monosyllable (FB MS) speech discrimination test. The health-related quality of life was measured with Nijmegen Cochlear implantation Questionnaire (NCIQ) whereas tinnitus-related distress was measured with the German version of Tinnitus Questionnaire (TQ)...

Drug-induced sleep endoscopy (DISE) is a reliable upper airway evaluation tool, widely used to improve surgical results in patients with obstructive sleep apnea (OSA). Several factors, including sleeping position and depth of sedation, affect DISE findings. This study aimed to evaluate the impact of physical stress on DISE findings. Eighty-five patients with OSA underwent two DISE examinations at the same level of sedation. The "first DISE" (control group) was performed after polysomnography, while the "second DISE" (test group) performed immediately after a treadmill stress test...

BACKGROUND There is a long-standing debate about the role of beta-adrenoceptor polymorphisms in the cardiovascular system. We wanted to elucidate whether β1-adrenoceptor-polymorphisms affects the postoperative catecholamine consumption and the length of intermediate care unit stay in patients undergoing cardiac surgery, and whether this might be enhanced or attenuated by catechol-O-methyl-transferase (COMT) polymorphism. MATERIAL AND METHODS We included 116 patients (63±1.2 years; 34% females; 81±1 kg) undergoing cardiac surgery...

BACKGROUND: Anterior cruciate ligament (ACL) injury is a well-known risk factor for the development of posttraumatic osteoarthritis (PTOA). However, whether using continuous passive motion (CPM) with or without additional treadmill exercise (TRE) in early ACL injury might provide chondroprotective effects and further decrease the risk of PTOA has yet to be determined. HYPOTHESIS: CPM may offer an enhanced chondroprotective effect, but TRE may attenuate that effect due to the mechanical stress on the joint and inflammatory cytokines in the joint...

There is growing evidence that chronic hyperglycemia leads to the formation of advanced glycation end products (AGEs) which exerts its effect via interaction with the receptor for advanced glycation end products (RAGE). AGE-RAGE activation results in oxidative stress and inflammation. It is well known that this mechanism is involved in the pathogenesis of cardiovascular disease in diabetes. Kaempferol, a dietary flavonoid, is known to possess antioxidant, anti-apoptotic, and anti-inflammatory activities. However, little is known about the effect of kaempferol on myocardial ischemia-reperfusion (IR) injury in diabetic rats...

BACKGROUND: During lobectomy in patients with lung cancer, the operated lung is often -collapsed and hypoperfused. Ischemia/reperfusion injury may then occur when the lung is -re-expanded. We hypothesized that remote ischemic preconditioning (RIPC) would decrease oxidative lung damage and improve gas exchange in the postoperative period. METHODS: We conducted a single-center, randomized, double-blind trial in patients with nonsmall cell lung cancer undergoing elective lung lobectomy...

BACKGROUND & AIMS: Cardiac surgery is accompanied by oxidative stress and systemic inflammatory response, which may be associated with organ dysfunction and increased mortality. Selenium and selenoenzymes are important constituents of anti-oxidative defense. We hypothesized that high-dose sodium selenite supplementation can attenuate the postoperative inflammation and might, therefore, improve clinical outcome. METHODS: Randomized, placebo-controlled, double-blinded, bi-center study on 411 adult patients undergoing elective cardiac surgery...

BACKGROUND: We examined the effects of treatment on the psychological well-being of patients with localized or advanced penile cancer using screening questionnaires to determine the consecutive need for psychosocial care. Penile cancer is a rare, but highly aggressive, malignancy. The psychological stress of patients with penile cancer arises from the cancer diagnosis per se and the corresponding consequences of treatment. In addition, cancer-specific distress results (eg, fear of metastasis, progression, relapse, death)...

Introduction: Obesity refers to the accumulation of fatty tissues and it favors the occurrence of oxidative stress. Alternatives that can contribute to body weight reduction have been investigated in order to reduce the production of reactive oxygen species responsible for tissue damage. The aim of the current study was to assess whether the oxidant and antioxidant markers of obese women before and after bariatric surgery were able to reduce oxidative damage. Method: We have assessed 16 morbidly obese women five days before and 180 days after the surgery...

Laparoscopic myomectomy, a minimally invasive procedure performed for the management of uterine leiomyomas involves a challenging aspect: excessive local bleeding. Hemorrhage control during laparoscopic myomectomy could be reached through the use of a wide range of vasoconstrictors including epinephrine. Epinephrine is frequently used for the control of local bleeding during surgery; however, it has been associated with several complications. In this case report, we present a rare and unique case of stress-induced cardiomyopathy, also known as Takotsubo cardiomyopathy (TC), caused by intra-myomal injection of epinephrine during laparoscopic myomectomy...

BACKGROUND: Major vessel hemorrhage in endoscopic, endonasal skull-base surgery is a rare but potentially fatal event. Surgical simulation models have been developed to train surgeons in the techniques required to manage this complication. This mixed-methods study aims to quantify the stress responses the model induces, determine how realistic the experience is, and how it changes the confidence levels of surgeons in their ability to deal with major vascular injury in an endoscopic setting...
