What did we catch? Predictors of infection after tissue expander-based breast reconstruction in a safety-net system.

Background: Infection is a common complication following tissue expander (TE)-based breast reconstruction. Few studies have examined risk factors specifically in the unique populations encountered at safety-net hospitals. The purpose of this study was to identify predictors of TE infection at Harris Health safety-net hospitals, which serve the third most populous county in the United States.

Artificial Intelligence Methods for the Argenta Classification of Deformational Plagiocephaly to Predict Severity and Treatment Recommendation.

Introduction: Deformational plagiocephaly (DP) can be classified into 5 severity types using the Argenta scale (AS). Patients with type III or higher require referral to craniofacial surgery for management. Primary care pediatricians (PCPs) are often the first to encounter patients with DP, but current screening methods are subjective, increasing the risk of bias, especially for clinicians with little exposure to this population.

Perceptions of Orthopaedic Sports Medicine Surgeons About Medical Cannabidiol Use: A Survey Study.

Introduction: Multiple studies exist identifying cannabidiol (CBD) as an effective part of an orthopaedic patient's pain regimen; however, there is a paucity of studies elucidating orthopaedic surgeons' perception of the use and prescription of CBD in the medical setting. This study surveys orthopaedic sports medicine surgeons about their previous education on and current perceptions and usage of CBD in their medical practice.

Methods: Between April 2023 and July 2023, orthopaedic sports medicine surgeons from across the country were surveyed.

Physician Trainees' Perception of Cannabidiol Use in Medicine: A Survey Study.

Purpose: Given the ongoing national opiate crisis, physicians have been challenged with mitigating the risk of opiate dependence in their patients. With current physician efforts to mitigate the risks of treating pain with opioid prescriptions, this study evaluates medical students' and residents' understanding and perceptions regarding cannabidiol (CBD) in current medical care and their future medical practice.

Methods: Orthopedic residents from all American programs and medical students from 50 medical schools, regardless of training year or future specialty plans, were eligible to participate in this survey-based study administered from December 2022 to March 2023.

Attitudes on Artificial Intelligence use in Pediatric Care From Parents of Hospitalized Children.

Introduction: Artificial intelligence (AI) may benefit pediatric healthcare, but it also raises ethical and pragmatic questions. Parental support is important for the advancement of AI in pediatric medicine. However, there is little literature describing parental attitudes toward AI in pediatric healthcare, and existing studies do not represent parents of hospitalized children well.

Technical/Algorithm, Stakeholder, and Society (TASS) barriers to the application of artificial intelligence in medicine: A systematic review.

Introduction: The use of artificial intelligence (AI), particularly machine learning and predictive analytics, has shown great promise in health care. Despite its strong potential, there has been limited use in health care settings. In this systematic review, we aim to determine the main barriers to successful implementation of AI in healthcare and discuss potential ways to overcome these challenges.

A High Rate of Bacteriologic Culture-Positive Findings Is Seen After Revision Rotator Cuff Surgery.

Purpose: To determine the incidence of subclinical infections in patients undergoing revision arthroscopic rotator cuff repair and identify any risk factors for developing these infections.

Methods: Patients who underwent revision surgery by the senior author between January 2012 and December 2022 after a previous rotator cuff surgery were identified. All patients undergoing an open or arthroscopic revision of their previous rotator cuff surgery were included.

The incidence of subclinical infection in patients undergoing revision shoulder stabilization surgery: a retrospective chart review.

Background: Shoulder instability continues to be a common problem that is difficult to treat. Part of this difficulty can be attributed to the numerous postoperative complications that can impact the clinical course. Our study aims to primarily identify the incidence of subclinical infection in patients undergoing revision shoulder stabilization surgery and secondarily identify any risk factors for developing a subclinical infection.

Reconstruction of High-Tension Scalp Defects by the Twizzler Technique: A Retrospective Case Series.

Background: Scalp wounds are difficult to close primarily because of the inelasticity of the galea, often requiring adjacent tissue transfer or grafting. It is still debated whether intraoperative tissue expansion can occur on the scalp.

Objective: We report our experience with the Twizzler technique, a form of intraoperative tissue expansion and load cycling, to achieve primary closure of high-tension scalp wounds.

Safety of exercise for adults with thoracic aortic aneurysms and dissections.

Background: Current guidelines for patients with thoracic aortic aneurysms or dissections (TAD) restrict vigorous exertion with the intention to prevent acute aortic dissections. However, a safe threshold for exercise intensity has not been established for TAD patients. In this study, we measured exertional changes in systolic and diastolic blood pressure during isometric and dynamic exercises in a cohort of TAD patients to determine safety of moderate intensity exercise.

Control of Neuroinflammation through Radiation-Induced Microglial Changes.

Microglia, the innate immune cells of the central nervous system, play a pivotal role in the modulation of neuroinflammation. Neuroinflammation has been implicated in many diseases of the CNS, including Alzheimer's disease and Parkinson's disease. It is well documented that microglial activation, initiated by a variety of stressors, can trigger a potentially destructive neuroinflammatory response via the release of pro-inflammatory molecules, and reactive oxygen and nitrogen species.

Stripes within words affect reading.

In a series of eight studies it is shown that the first peak in the horizontal autocorrelation of the image of a word (which captures the similarity in shape between the neighbouring strokes of letters) determines (i) the appearance of the words as striped; (ii) the speed with which the words are read, both aloud and silently; and (iii) the speed with which a paragraph of text can be searched. By subtly distorting the horizontal dimension of text, and thereby reducing the first peak in the horizontal autocorrelation, it is shown that the speed of word recognition can be increased. The increase in speed is greater in poor readers.

Early diagnosis of breast cancer by hair diffraction.

A correlation between the incidence of breast cancer and an observed change in the X-ray diffraction pattern of hair from the afflicted individuals was first reported in 1999. Since that time, over 500 hair samples have been analyzed in double-blinded breast cancer studies with no false negatives being detected. To correlate this observed change with the presence of breast cancer, we examined whiskers removed from nude mice prior to and 8 weeks after subcutaneous implantation of a human breast cancer cell line.
