#1
Takashi Kunihara
The two major valve-sparing root replacement procedures, aortic valve reimplantation (reimplantation) and aortic root remodeling (remodeling), have advantages and disadvantages, which are reviewed herein. The main advantage of reimplantation is the resulting annular support, and the disadvantages are the unfavorable hemodynamics and relatively long procedure time. The main advantages of remodeling are the physiological hemodynamics and decreased procedure time, and the disadvantage is the lack of annular support...

AIMS/HYPOTHESIS: Roux-en-Y gastric bypass (RYGB) surgery is characterised by glycaemic variability. Prospective studies of glucose metabolism in pregnancy after RYGB are not available, therefore this study aimed to evaluate physiological alterations in glucose metabolism in pregnancy following RYGB. METHODS: Sixty-three pregnant women (25 who underwent RYGB, 19 non-operated obese control women and 19 normal weight control women) were included. Frequently sampled 3 h OGTTs and 1 h IVGTTs were performed between 24 and 28 weeks of gestation and, in a subgroup, were repeated at 3-6 months after delivery...

OBJECTIVE: Postoperative cognitive dysfunction is an important complication of cardiac surgery with poor outcomes. Serum glial cell line-derived neurotrophic factor levels are decreased in patients with Alzheimer's disease, but the association between glial cell line-derived neurotrophic factor levels and postoperative cognitive dysfunction is poorly understood. The present study aimed to investigate the prognostic value of postoperative serum glial cell line-derived neurotrophic factor levels to predict postoperative cognitive dysfunction in patients with rheumatic heart disease undergoing heart valve replacement...

INTRODUCTION: Thyroid and parathyroid surgery (TPTS) is associated with risk of injury to the recurrent laryngeal nerve, superior laryngeal nerve and voice changes. Intraoperative neuromonitoring (IONM), intermittent or continuous, evaluates the functional state of the laryngeal nerves and is being increasingly used. This means that points of consensus on the most controversial aspects are necessary. OBJECTIVE: To develop a support document for guidance on the use of IONM in TPTS...

BACKGROUND: The technique of in utero electroporation has been widely used in eutherians, such as mice and rats, to investigate brain development by selectively manipulating gene expression in specific neuronal populations. A major challenge, however, is that surgery is required to access the embryos, affecting animal survival and limiting the number of times it can be performed within the same litter. New method: Marsupials are born at an early stage of brain development as compared to eutherians...

PURPOSE: Loss of full wrist range of motion is common after treatment of distal radius fractures. Loss of wrist extension limiting functional activities, although uncommon, can occur after volar plating of distal radius fractures. Unlike other joints in which capsular release is a common form of treatment for stiffness, this has been approached with caution in the wrist owing to concerns for carpal instability. We tested the null hypothesis that hardware removal and open volar capsular release would not lead to improved upper extremity-specific patient-reported outcome (Disabilities of the Arm, Shoulder, and Hand [DASH] questionnaire)...

Maximal safe resection is the cornerstone of treatment for low-grade and high-grade gliomas. In addition to high-resolution anatomic MRI studies that highlight tumor architecture, it is important to determine the relationship of the tumor to the eloquent cortical and subcortical areas to avoid introducing or exacerbating a neurologic deficit. The goal of this review was to highlight imaging modalities that provide functional information and can be integrated with intraoperative MRI navigation to maximize the extent of resection while preserving a patient's neurologic function...

OBJECTIVES: Craniopharyngioma is a slow-growing tumor, but long-term tumor control with maintenance of quality of life is sometimes very difficult to achieve, and hypothalamic disturbance should be strictly avoided in the treatment. However, management of the pituitary gland and/or pituitary stalk varies among surgeons and institutions. PATIENTS AND METHODS: This retrospective review identified 44 patients, 24 males and 20 females with craniopharyngiomas who were initially treated by surgery through the extended transsphenoidal approach with pituitary stalk sectioning at a single institute...

PURPOSE: The purpose of this study was to describe patterns of pain during the first year following total knee arthroplasty (TKA) and evaluate pre- and postoperative factors associated with pain and patient satisfaction at 1 year. It was hypothesized that more severe preoperative pain would be associated with more residual pain and lower patient satisfaction 1 year after surgery. METHODS: A longitudinal cohort study was performed with repeated measures of pain (0-10 numeric rating scale) and evaluation of other self-reported symptoms (Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, and Fatigue Severity Score), daily functioning (Lawton Instrumental Activities of Daily Living Scale), quality of life (EQ-5D-3L), knee function (KSS Knee and Function Score), perioperative and clinical characteristics (e...

BACKGROUND: Single-port laparoscopic surgery (SPLS) was recently introduced as an innovative minimally invasive surgery method. Retrospective studies have revealed the safety and feasibility of SPLS for colon cancer treatment. However, no prospective randomized trials have been performed. The multicenter, randomized SIMPLE (single-port versus multiport laparoscopic surgery) trial aimed to investigate short-term perioperative outcomes of SPLS for colon cancer treatment, compared with multiport laparoscopic surgery (MPLS)...

INTRODUCTION: Priapism is defined as a full or partial erection lasting longer than 4 hours after sexual stimulation and orgasm or unrelated to sexual stimulation. The main goal of priapism management is to resolve the episode immediately to preserve erectile function and penile length. Corporal smooth muscle necrosis is likely to have already occurred, and medically refractory erectile dysfunction is expected in patients with a protracted episode. Penile prosthesis implantation (PPI) in the early or late phase of priapism can restore erectile function...

Facial Paralysis (FP) profoundly impairs the life of individuals, both functionally and psychosocially. Surgical approaches to treat this condition are myriad, but the ultimate goal is to restore symmetry and movement. Ablative surgery for tumors of the head and neck region are amongst the most common etiologies causing FP and this group of patients represents unique challenges. Surgical defects may have multiple competing reconstructive requirements and addressing the FP must be considered in this context...

BACKGROUND: Carbon-dioxide (CO2)-pneumothorax during minimally invasive surgery induces well-known metabolic changes. However, little is known about its impact on the central nervous system. The aim of this work is to evaluate the acute impact of CO2-pneumothorax over central cytokine response and its long-term effect on animal behavior. METHODS: This is an experimental study where neonatal Sprague-Dawley rats are submitted to CO2-pneumothorax. Peripheral and central cytokine response was evaluated 24h after insufflation, and peripheral immune cell phenotyping was evaluated 24h and 4weeks post-insufflation...

Roux-en-Y gastric bypass (RYGB) surgery is one of the most effective treatments for obesity and type II diabetes. RYGB was originally believed to work by mechanically restricting caloric intake or causing macronutrient malabsorption. However, such mechanical effects play no role in the remarkable efficacy of gastric bypass. Instead, mounting evidence shows that altered neuroendocrine signaling is responsible for the weight reducing effects of RYGB. The exact mechanism of this surgical response is still a mystery...

Near-infrared fluorescence (NIRF) dyes have recently emerged as promising tools for non-invasive imaging of different types of cancers. Here, we explored the potential utility of a NIRF DZ-1 dye, with dual imaging and tumour targeting functions, in hepatocellular carcinoma (HCC). We showed the preferential uptake of DZ-1 by HCC cells in vitro and in derived subcutaneous/orthotopic tumour xenografts, accompanied by a minimal effect on normal cells. DZ-1 simplified tumour growth profiling as well, since we were able to correlate NIRF signals with tumour volume and/or tumour-emitting luminescence in mice...
