Rhinoplasty in the COVID-19 Era: Practice and Safety Considerations.

The COVID-19 pandemic has required changes in health care practices to decrease the risk of disease transmission during the provision of medical care. The risk of transmission is high in procedures involving the nasopharyngeal and oropharyngeal tissues. This article describes simple preventative strategies at a single institution to minimize the risk of disease transmission during rhinoplasty procedures.

Standards of Care for the Health of Transgender and Gender Diverse People, Version 8.

Transgender healthcare is a rapidly evolving interdisciplinary field. In the last decade, there has been an unprecedented increase in the number and visibility of transgender and gender diverse (TGD) people seeking support and gender-affirming medical treatment in parallel with a significant rise in the scientific literature in this area. The World Professional Association for Transgender Health (WPATH) is an international, multidisciplinary, professional association whose mission is to promote evidence-based care, education, research, public policy, and respect in transgender health.

Predicting rare outcomes in abdominal wall reconstruction using image-based deep learning models.

Background: Deep learning models with imbalanced data sets are a challenge in the fields of artificial intelligence and surgery. The aim of this study was to develop and compare deep learning models that predict rare but devastating postoperative complications after abdominal wall reconstruction.

Methods: A prospectively maintained institutional database was used to identify abdominal wall reconstruction patients with preoperative computed tomography scans.

Combination non-invasive radiofrequency and electrical muscle stimulation: A synergistic combination for body contouring.

Introduction: Patients desiring noninvasive body contouring increasing require a more comprehensive approach to soft tissue laxity, muscle, and adipose hypertrophy. Previous devices have typically focused on only adipose reduction, without impact on muscle or skin laxity. This study describes the first use of noninvasive bipolar radiofrequency in combination with electromagnetic muscle stimulation.

A Randomized Trial to Assess Effectiveness and Safety of a Hyaluronic Acid Filler for Chin Augmentation and Correction of Chin Retrusion.

Background: The chin is important for facial appearance, affecting overall balance and harmony of the face. The purpose of this study was to evaluate effectiveness of the hyaluronic acid filler Restylane Defyne for chin augmentation and correction of chin retrusion versus a no-treatment control.

Methods: Male and female subjects, aged 22 years or older, with mild to moderate chin retrusion, were randomized 3:1 to the hyaluronic acid filler Restylane Defyne ( n = 107) or no treatment ( n = 33).

Macrophage-mediated PDGF Activation Correlates With Regenerative Outcomes Following Musculoskeletal Trauma.

Objective: Our objective was to identify macrophage subpopulations and gene signatures associated with regenerative or fibrotic healing across different musculoskeletal injury types.

Background: Subpopulations of macrophages are hypothesized to fine tune the immune response after damage, promoting either normal regenerative, or aberrant fibrotic healing.

Methods: Mouse single-cell RNA sequencing data before and after injury were assembled from models of musculoskeletal injury, including regenerative and fibrotic mouse volumetric muscle loss (VML), regenerative digit tip amputation, and fibrotic heterotopic ossification.

Macrophage TGF-β signaling is critical for wound healing with heterotopic ossification after trauma.

Transforming growth factor-β1 (TGF-β1) plays a central role in normal and aberrant wound healing, but the precise mechanism in the local environment remains elusive. Here, using a mouse model of aberrant wound healing resulting in heterotopic ossification (HO) after traumatic injury, we find autocrine TGF-β1 signaling in macrophages, and not mesenchymal stem/progenitor cells, is critical in HO formation. In-depth single-cell transcriptomic and epigenomic analyses in combination with immunostaining of cells from the injury site demonstrated increased TGF-β1 signaling in early infiltrating macrophages, with open chromatin regions in TGF-β1-stimulated genes at binding sites specific for transcription factors of activated TGF-β1 (SMAD2/3).

A Randomized Trial of Enteral Glutamine for Treatment of Burn Injuries.

Background: Glutamine is thought to have beneficial effects on the metabolic and stress response to severe injury. Clinical trials involving patients with burns and other critically ill patients have shown conflicting results regarding the benefits and risks of glutamine supplementation.

Methods: In a double-blind, randomized, placebo-controlled trial, we assigned patients with deep second- or third-degree burns (affecting ≥10% to ≥20% of total body-surface area, depending on age) within 72 hours after hospital admission to receive 0.

Longevity of ptosis correction in mastopexy and reduction mammaplasty: A systematic review of techniques.

Background: Mastopexy and reduction mammaplasty are commonly performed procedures in plastic surgery with many variations in incision pattern, pedicle design, and additional support maneuvers. Aesthetically pleasing on table results are widely accomplished; however, the longevity of the outcome and sustained correction of ptosis or pseudoptosis is not universal. A systematic review of mastopexy and reduction mammaplasty procedures was performed to investigate which techniques provided the greatest long-term correction of ptosis.

BETA PRIME: Phase I study of AdAPT-001 as monotherapy and combined with a checkpoint inhibitor in superficially accessible, treatment-refractory solid tumors.

AdAPT-001 is an investigational therapy consisting of a replicative type 5 adenovirus armed with a TGF-β receptor-immunoglobulin Fc fusion trap, designed to neutralize isoforms 1 and 3 of the profibrotic and immunosuppressive cytokine, TGF-β. In preclinical studies with an immunocompetent mouse model, AdAPT-001 eradicated directly treated 'cold' tumors as well as distant untreated tumors, and, from its induction of systemic CD8 T cell-mediated antitumor immunity, protected the mice from rechallenge with tumor cells. AdAPT-001 also sensitized resistant tumors to checkpoint blockade.

Safety and Efficacy of Transform for Noninvasive Lipolysis and Circumference Reduction of the Abdomen.

Noninvasive body contouring has seen a precipitous rise in popularity since its advent in the early 2000s. With this rise in popularity, there has been an expansion in the types and number of noninvasive devices for muscle hypertrophy and fat lipolysis. The Transform radiofrequency and electrical muscle stimulation device is a newly introduced device for noninvasive abdominal body contouring.
