The pathophysiologic side effects of cardiopulmonary bypass have already been identified. Minimally invasive extracorporeal circulation technologies (MiECT) and off-pump coronary artery bypass graft surgery (OPCABG) aim to reduce these problems. This metaanalysis provides a comparison of MiECT and OPCABG in randomized and observational studies. A fully probabilistic, Bayesian approach of primary and secondary endpoints was conducted. MiECT does not give inferior results when compared with OPCABG. However, there is a trend to borderline significantly higher blood loss in this group in randomized controlled trials...

Background: Weight-related stigma is reported frequently by higher body-weight patients in healthcare settings. Bariatric surgery triggers profound weight loss. This weight loss may therefore alleviate patients' experiences of weight-related stigma within healthcare settings. In non-clinical settings, weight-related stigma is associated with weight-inducing eating patterns. Dietary adherence is a major challenge after bariatric surgery. Objectives: (1) Evaluate the relationship between weight-related stigma and post-surgical dietary adherence; (2) understand if weight loss reduces weight-related stigma, thereby improving post-surgical dietary adherence; and (3) explore provider and patient perspectives on adherence and stigma in healthcare settings...

Kinesin family protein 2A (KIF2A), an M-type nonmotile microtubule depolymerase, has attracted attention for its role in carcinogenesis and poor prognoses in various human cancers. In this study, we aimed to evaluate the expression of KIF2A and its robustness and potential to predict clinical outcomes in gastric cancer (GC) patients. The messenger RNA (mRNA) expression of KIF2A was determined in 24 pairs of cancerous and adjacent nontumor tissues by real-time polymerase chain reaction. Immunohistochemistry of KIF2A was performed on a tissue microarray composed of 461 GC and 65 matched adjacent nontumor tissues removed during surgeries and 18 chronic gastritis, 15 intestinal metaplasia, and 37 low-grade and 62 high-grade intraepithelial neoplasias acquired through gastric endoscopic biopsies...

BACKGROUND AND PURPOSE: Due to well-developed Circle of Willis in pigs, it is technically challenging to make persistent focal ischemic stroke based on occlusion of cerebral arteries. Endothelin-1 could cause a focal lesion by forcing transient but strong vasoconstriction in the circumscribed injected area. Its use in porcine stroke model has drawn attention lately. However, all the porcine endothelin-1 induced models were euthanized soon after surgery. Whether the brain lesion is persistent, and whether they could cause neurological deficit are not known...

BACKGROUND: Current guidelines recommend pelvic lymphadenectomy (PLND) for patients with pelvic lymph node metastasis and special state. However, these data and recommendations do not distinguish the role of PLND in different patient groups and confirm the final benefits. The aim of this study was to confirm the efficacy of pelvic lymphadenectomy (PLND) for the different groups of patients. METHODS: Data obtained from 7 centers were retrospectively analyzed. Of the patients, 190 pN2-3 penile carcinoma patients confirmed by bilateral inguinal lymph node excision were included in this study...

Cochlear implant (CI) is an artificial electronic device which can provide a sense of sound to a patient with severe or profound hearing loss. Pathological changes have been observed after CI surgery, which might influence the effectiveness of the CI procedure. In this review, we divided the postoperative pathological changes of the temporal bone into two categories according to different stages: immediate trauma and delayed side effects. Immediate trauma might arise from traumatic insertion of the electrode during CI surgery, which included trauma at cochleostomy site, lateral wall trauma, basilar membrane injury, osseous lamina fracture and modiolar injury...

BACKGROUND: For the N1b papillary thyroid carcinoma (PTC) patients, modified radical neck dissection (MRND) encompassing levels II - V is generally recommended. However, routine level V dissection is controversial because of the low incidence of metastasis/recurrence in level V and the increased morbidities associated with level V dissection. METHODS: We retrospectively reviewed 646 N1b PTC patients who underwent unilateral MRND between January 1997 and June 2015...

Propel and Propel Mini sinus implants are mometasone furoate-coated bioabsorbable stents used as an adjunct in the management of chronic rhinosinusitis after endoscopic sinus surgery. The original sinus implant was deployed in the ethmoid sinuses to provide medialization of the middle turbinate, decrease scarring and mucosal adhesions, limit polyp regrowth, and reduce mucosal inflammation. A structurally smaller version of the Propel, the Propel Mini, was developed and now has been approved for endoscopic placement in the frontal sinuses...

BACKGROUND: Cementless fixation of total hip arthroplasties (THAs) is often favored in young, high-demanding patients due to the conservation of valuable bone-stock and easier revision if loosening has occurred. Long-term outcome data of the spongy metal structured implant used in the present study in patients younger than 65 years are still lacking. METHODS: We conducted a retrospective chart review and functional investigation (Merle d'Aubigné score, SF-12) of patients younger than 65 years at implantation treated with a spongy metal structured THA (n = 79) from one orthopedic university center from 1985 to 1989...
