Effects of Social Determinants of Health and Social Support on Surgical Outcomes Among Patients Undergoing Hysterectomy.

Objective: To describe composite 30-day postoperative complication rates among patients undergoing hysterectomy during the coronavirus disease 2019 (COVID-19) pandemic and to determine baseline and postoperative mental health symptoms, levels of social support, and socioeconomic status and their association with hysterectomy outcomes.

Methods: This multicenter prospective cohort study at eight centers across the United States enrolled patients who underwent minimally invasive hysterectomy for benign indications during the COVID-19 pandemic. Patients completed preoperative and postoperative surveys assessing mental health (PHQ-9 [Patient Health Questionnaire]), social support (MOS-SS [Medical Outcomes Study Social Support Survey]), and socioeconomic status (Hollingshead Index [Hollingshead Four Factor Index of Socioeconomic Status]).

Barriers to retinopathy screening in youth and young adults with type 1 diabetes.

Early detection of diabetic retinopathy (DR) is imperative; however, adherence to screening guidelines is poor. We hypothesized that youth and young adults with type 1 diabetes (T1D) who met American Diabetes Association criteria for recommended DR screening at the time of the study (10 years old or greater with diabetes duration of 5 years or more) would report multiple barriers to screening and that targeted barriers and subpopulations could be identified to improve access to care. 271 youth aged 10 to 26 years with T1D of at least 5 years duration were recruited from clinic, diabetes camp, and a diabetes conference and completed a patient-reported questionnaire.

Real-World Screening for Retinopathy in Youth With Type 1 Diabetes Using a Nonmydriatic Fundus Camera.

Objective: To assess the use of a portable retinal camera in diabetic retinopathy (DR) screening in multiple settings and the presence of associated risk factors among children, adolescents, and young adults with type 1 diabetes.

Design And Methods: Five hundred youth with type 1 diabetes of at least 1 year's duration were recruited from clinics, diabetes camp, and a diabetes conference and underwent retinal imaging using a nonmydriatic fundus camera. Retinal characterization was performed remotely by a licensed ophthalmologist.

Corneal keratin aggresome (CKAGG) formation and clearance by proteasome activation.

Purpose: To understand the mechanism of corneal keratin expression and clearance in corneal epithelium with Limbal Stem Cell Deficiency (LSCD). The hypothesis is that LSCD-induced proteasome dysfunction is a contributing factor to keratin aggregation, causing corneal keratin aggresome (CKAGG) formation.

Method: LSCD was surgically induced in rabbit corneas.

Proteasomes in corneal epithelial cells and cultured autologous oral mucosal epithelial cell sheet (CAOMECS) graft used for the ocular surface regeneration.

Purpose: This study focuses on characterizing proteasomes in corneal epithelial cells (CEC) and in cultured autologous oral mucosal epithelial cell sheets (CAOMECS) used to regenerate the ocular surface.

Methods: Limbal stem cell deficiency (LSCD) was surgically induced in rabbit corneas. CAOMECS was engineered and grafted onto corneas with LSCD to regenerate the ocular surface.

The Role of E-Cadherin in Maintaining the Barrier Function of Corneal Epithelium after Treatment with Cultured Autologous Oral Mucosa Epithelial Cell Sheet Grafts for Limbal Stem Deficiency.

The role of E-cadherin in epithelial barrier function of cultured autologous oral mucosa epithelial cell sheet (CAOMECS) grafts was examined. CAOMECS were cultured on a temperature-responsive surface and grafted onto rabbit corneas with Limbal Stem Cell Deficiency (LSCD). E-cadherin levels were significantly higher in CAOMECS compared to normal and LSCD epithelium.
