Nipple-areolar complex sensory recovery based on incision placement after nipple-sparing mastectomy: a prospective nonrandomized controlled trial.

Introduction: Nipple-sparing mastectomy (NSM) aims to improve patient satisfaction by preserving the nipple-areola complex (NAC) while ensuring oncologic safety. Different surgical incisions, such as inframammary fold (IMF) and periareolar/radial incisions, are used in NSM; however, their impact on NAC sensory loss remains unclear. In this study, the authors aimed to assess NAC sensation after NSM and compare the results of different incisional approaches, specifically IMF versus periareolar/radial.

Pre-Melting-Assisted Impurity Control of β-GaO Single Crystals in Edge-Defined Film-Fed Growth.

This study reveals the significant role of the pre-melting process in growing high-quality (100) β-GaO single crystals from 4N powder (99.995% purity) using the edge-defined film-fed growth (EFG) method. Among various bulk melt growth methods, the EFG method boasts a fast growth rate and the capability of growing multiple crystals simultaneously, thus offering high productivity.

Cancer-related health behaviors during the COVID 19 pandemic in geographically diverse samples across the US.

Background: The COVID-19 pandemic involved business closures (e.g., gyms), social distancing policies, and prolonged stressful situations that may have impacted engagement in health behaviors.

Association of lung function with visceral adiposity and skeletal muscle mass considering myosteatosis.

Background: Changes in body composition, including loss of muscle mass and obesity, adversely affect lung function.

Research Question: What is the relationship between lung function, visceral adiposity, and skeletal muscle mass, considering myosteatosis measured using computed tomography (CT) scans in middle-aged Korean adults?

Study Design And Methods: We reviewed 15,827 participants (9237 men and 6590 women), with a mean age of 52.5 ± 8.
