Purpose The goals of immediate postmastectomy breast reconstruction are to minimize deformity and optimize quality of life as perceived by patients. We prospectively evaluated patient-reported outcomes (PROs) in women undergoing immediate implant-based or autologous reconstruction. Methods Women undergoing immediate postmastectomy reconstruction for invasive cancer and/or carcinoma in situ were enrolled at 11 sites. Women underwent implant-based or autologous tissue reconstruction. Patients completed the BREAST-Q, a condition-specific PRO measure for breast surgery patients, and Patient-Reported Outcomes Measurement Information System-29, a generic PRO measure, before and 1 year after surgery...

Polymeric sublaminar cables have a number of advantages over metal cables in the field of spinal deformity surgery, with decreased risk of neurological injury and potential for higher correction forces as the two most predominant. However, currently available polymer cables are radiolucent, precluding postoperative radiological assessment of instrumentation stability and integrity. This study provides a preclinical assessment of a woven UHMWPE cable made with radiopaque UHMWPE fibers. Our primary goal was to determine if the addition of a radiopacifier negatively affects the mechanical properties of UHMWPE woven cables...

The benefits of cochlear implantation (CI) in the elderly remain debatable in terms of sound and speech perception. Moreover, the results of CI may be affected by the intensity and pitch of spoken language. We conducted a retrospective study to evaluate surgical and hospitalization times, postoperative complications, and hearing outcomes after CI in elderly Koreans. Our study population was made up of 55 postlingually deafened adults who underwent unilateral CI. They were divided into two groups based on age; an older group consisted of 21 patients aged 65 years or older (mean 71...

Liver kinase B1 (LKB1) is a serine/threonine protein kinase ubiquitously expressed in mammalian cells. It was first identified in Peutz-Jeghers syndrome as a tumor suppressor gene. Whether endothelial LKB1 regulates angiogenesis and tumor growth is unknown. In this study, we generated endothelial cell-specific LKB1-knockout (LKB1(endo-/-)) mice by crossbreeding vascular endothelial-cadherin-Cre mice with LKB1(flox/flox) mice. Vascular endothelial growth factor (VEGF) level was highly co-stained in endothelial cells but not in macrophages in LKB1(endo-/-) mice...

INTRODUCTION: The latissimus dorsi (LD) myocutaneous flap has been a long term standard for breast reconstruction. The variable indications for the LD flap have not been statistically examined because of the relative infrequency of its use by any single surgeon or institution. METHODS: The Nationwide Inpatient Sample data set was queried for all patient encounters involving a LD myocutaneous flap procedure. The study population was further restricted to female patients with a history of breast cancer or previous mastectomy...

Autologous NP cell implantation is a potential therapeutic avenue for intervertebral disc (IVD) degeneration. However, monolayer expansion of cells isolated from surgical samples may negatively impact matrix production by way of dedifferentiation. Previously, we have used a continuous expansion culture system to successfully preserve a chondrocyte phenotype. In this work, we hypothesised that continuous expansion culture could also preserve nucleus pulposus (NP) phenotype. We confirmed that serial passaging drove NP dedifferentiation by significantly decreasing collagen type II, aggrecan and chondroadherin (CHAD) gene expression, compared to freshly isolated cells...
