Enhanced recovery after surgery (ERAS) is a new perioperative concept that aims to reduce perioperative stress response and accelerate rehabilitation of patients through a variety of optimized management. With the wider application of this concept,the effective implementation of ERAS program has become a new challenge. Cardiopulmonary exercise testing (CPET) has shown promising value in the preoperative assessment,perioperative optimization,and postoperative rehabilitation of ERAS. This article reviews the application of CPET in ERAS,with an attempt to provide evidence for more detailed and comprehensive ERAS program...

Before surgery for primary aldosteronism (PA), localization is evaluated with adrenal vein sampling (AVS). A 56-year-old Japanese woman had a right adrenal mass, hypokalemia, and a high aldosterone/renin ratio. Stress tests confirmed the diagnosis of PA. Subsequently, preoperative AVS was performed and right adrenal hemorrhage (AH) occurred unexpectedly. Because hypertension persisted, laparoscopic right adrenalectomy was performed. Postoperatively, the blood pressure was normalized. Pathological examination revealed an adrenal cortical adenoma largely unaffected by necrosis and hemorrhage...

BACKGROUND: Acute kidney injury (AKI) after cardiac surgery is associated with increased short- and long-term mortality. Inflammation, oxidative stress, and endothelial dysfunction and damage play important roles in the development of AKI. High-density lipoproteins (HDLs) have anti-inflammatory and antioxidant properties and improve endothelial function and repair. Statins enhance HDL's anti-inflammatory and antioxidant capacities. We hypothesized that a higher preoperative HDL cholesterol concentration is associated with decreased AKI after cardiac surgery and that perioperative statin exposure potentiates this association...

BACKGROUND: Aortic regurgitation is a prevalent, detrimental complication of left ventricular assist devices (LVADs). The altered hemodynamics of LVADs results in aortic valves (AVs) having distinct mechanical stimulation. Our hypothesis was that the altered AV hemodynamics modulates the valve cells and matrix, resulting in changes in valvular mechanical properties that then can lead to regurgitation. METHODS: AVs were collected from 16 LVAD and 6 non-LVAD patients at time of heart transplant...

BACKGROUND AND PURPOSE: Carotid plaque contains biologically active substances released into the blood during carotid artery stenting (CAS). The main purpose of this prospective study was to analyse sequential changes in oxidative stress during CAS and their relationship to clinical factors. METHODS: Twenty-two consecutive CAS procedures were performed between May 2014 and April 2016. Arterial blood was collected four times: (1) after the sheath insertion without edaravone; (2) pre-angioplasty with edaravone from the carotid artery; (3) after post-stenting angioplasty from an occluded carotid artery; and (4) before sheath removal...

Background: The perioperative period is important for patient outcome. Colorectal cancer surgery can lead to metastatic disease due to release of disseminated tumor cells and the induction of surgical stress response. To explore the overall effects on surgically-induced changes in serum composition, in vitro model systems are useful. Methods: A systematic search in PubMed and EMBASE was performed to identify studies describing in vitro models used to investigate cancer cell growth/proliferation, cell migration, cell invasion and cell death of serum taken pre- and postoperatively from patients undergoing colorectal tumor resection...

OBJECTIVE: Adjustment in the doses of opioids has been a focus of interest for achieving better fast-track conditions in cardiac anesthesia, but relatively sparse information exists on the potential effect of psychologic and behavioral factors, such as stress, anxiety, and type of personality, on anesthesia requirements and patient turnover in the cardiac recovery unit (CRU); to the authors' knowledge, this particular focus has not been systematically investigated. In this randomized study, the authors tested the hypothesis that low-dose sufentanil, compared with a standard dose, can improve fast-track parameters and the overall quality of recovery...

INTRODUCTION AND HYPOTHESIS: Urethral pressure reflectometry (UPR) has proven highly reproducible in women with pelvic organ prolapse. We hypothesized that urethral parameters would decrease after anterior colporrhaphy. METHODS: A prospective, observational study where women with anterior vaginal wall prolapse ≥stage II were assessed before and after anterior colporrhaphy. Assessments consisted of prolapse staging according to the Pelvic Organ Prolapse Quantification system, UPR measurements at rest, during squeezing and straining (at a standardized abdominal pressure of 50 cmH2O, PO-Abd 50), standardized stress tests with 300 ml saline, and answering the International Consultation on Incontinence - Urinary incontinence short form...

Screw and plate fixation is commonly used to treat bone fractures. A prototype application (APP) for presurgical simulation was developed and validated by comparing it with current analytical approach and other models. In this APP, alternative plate designs and materials to limit the effects of stress shielding could be tested. In addition, the number and position of screws and the gap between bone and plate that achieved acceptable stability were predicted. The fixation stability providing a situation of interfragmentary strain between 2% and 10% is necessary for callus formation...
