Comparing Gender Congruency in Nonsurgical versus Postsurgical Top Surgery Patients: A Prospective Survey Study.

Background: Gender dysphoria can result in reduced quality of life. Treatments include hormone replacement therapy (HRT) and gender-affirming surgery. Our study compared congruency, satisfaction, and discrimination in patients who underwent top surgery and HRT versus HRT alone.

Defining Key Features in Patient Perspectives of Hand Aesthetics.

Background: The hand is highly visible and contributes to an individual's aesthetic image and perceived age. Current perspectives on hand aesthetics are primarily based on expert opinion rather than on lay population perspectives, which are less understood. Our study explores general population perceptions on the features that contribute most to an attractive hand.

Impending Backlog of Cleft Palate Patients Due to COVID-19.

Coronavirus disease 2019 (COVID-19) has placed an unprecedented strain on healthcare systems worldwide, but while high-income countries (HICs) have been able to adapt, low- and middle-income countries (LMICs) have been much slower to do so due to a lack of funding, skilled healthcare providers, equipment, and facilities. The redistribution of resources to combat the pandemic in LMICs has resulted in decreased surgical volumes at local surgical centers as well as a dramatic reduction in the number of humanitarian aid missions. Despite recent global investment in improving the surgical capacities of LMICs, even in the pre-COVID-19 era there was a vast unmet surgical need.

Rethinking Farkas: Updating Cephalic Index Norms in a Large, Diverse Population.

Background: Cephalic index, the ratio of head width to length, is one normative indicator used by insurers to derive criteria for plagiocephaly helmet authorization. Current norms were established by a small sample of white children in the 1987 Farkas and Munro data set. This study establishes updated cephalic index values for infants and children in a large, diverse patient population.

The Use of Visible-Light Hyperspectral Imaging in Evaluating Burn Wounds: A Case Report.

Burn depth is a critical factor in determining the healing potential of a burn as the extent of injury ultimately guides overall treatment. Visible-Light Hyperspectral Imaging is an FDA-approved, noninvasive, and noncontrast imaging technology that uses light waves within the visible spectrum to evaluate skin and superficial soft tissue perfusion. In this case report, visible-light hyperspectral imaging was used to evaluate a 37-year-old male who presented to the Emergency Department with a thermal burn of the trunk, back, and right upper extremity.

Hedgehog Pathway Activation Requires Coreceptor-Catalyzed, Lipid-Dependent Relay of the Sonic Hedgehog Ligand.

Hedgehog signaling governs critical processes in embryogenesis, adult stem cell maintenance, and tumorigenesis. The activating ligand, Sonic hedgehog (SHH), is highly hydrophobic because of dual palmitate and cholesterol modification, and thus, its release from cells requires the secreted SCUBE proteins. We demonstrate that the soluble SCUBE-SHH complex, although highly potent in cellular assays, cannot directly signal through the SHH receptor, Patched1 (PTCH1).

Repurposing Hsp90 inhibitors as antibiotics targeting histidine kinases.

To address the growing need for new antimicrobial agents, we explored whether inhibition of bacterial signaling machinery could inhibit bacterial growth. Because bacteria rely on two-component signaling systems to respond to environmental changes, and because these systems are both highly conserved and mediated by histidine kinases, inhibiting histidine kinases may provide broad spectrum antimicrobial activity. The histidine kinase ATP binding domain is conserved with the ATPase domain of eukaryotic Hsp90 molecular chaperones.
