The Moderating Effect of Age on Patient-Reported Benefits From Operative Management of Intra-Articular Distal Radius Fractures: A Meta-Regression Analysis.

Purpose: The optimal treatment of intra-articular distal radius fractures in older adults (>65 years) remains uncertain despite numerous randomized trials. The purpose of this study was to examine the moderating effect of age on patient-reported benefits of volar locked plating versus cast immobilization for intra-articular distal radius fractures.

Methods: A meta-analysis of randomized controlled trials was conducted to compare volar locked plating and cast immobilization of intra-articular distal radius fractures.

An Examination of Racial and Ethnic Disparities in the Use of Prostate Biopsy and Magnetic Resonance Imaging in Prostate Cancer Screening.

Introduction: We assessed racial and ethnic disparities in the use of prostate biopsy or MRI following an elevated PSA result.

Methods: We retrospectively evaluated insurance claims from Optum's de-identified Clinformatics Data Mart database from January 1, 2011 to December 31, 2017. This was a large commercially insured cohort from across the United States.

Programa de diabetes: improving diabetes care for undocumented immigrants using the Chronic Care Model at a free community clinic.

Aims: This study examined whether the Chronic Care Model can be successfully applied to improve health outcome measures for uninsured, undocumented immigrants with diabetes at a free, non-federally funded community clinic.

Methods: Data were collected from 128 uninsured, undocumented immigrants enrolled in Programa de diabetes, a comprehensive diabetes program at People's Health Clinic based on the six core elements of the Chronic Care Model. All study participants self-identified by the Hispanic ethnicity.

Turner Syndrome: Ocular Manifestations and Considerations for Corneal Refractive Surgery.

Turner Syndrome (TS) is the most common sex chromosome abnormality in females and is associated with physical changes, hormone deficiencies, increased risk of autoimmune disease, and ocular complications. In this article, we review the main ocular findings associated with TS and discuss their significance for the patient considering refractive surgery. We also present four cases of TS to highlight the clinical findings that may be present in these patients.

Ocular Side Effects of Bisphosphonates: A Review of Literature.

In rare cases, bisphosphonates are well established to cause ocular inflammation, presenting as uveitis, episcleritis, scleritis, orbital inflammation, and/or conjunctivitis. Some reports of bisphosphonate-associated neuro-ophthalmic complications also exist. We identified 101 reports in the literature relating to bisphosphonate-associated ocular complications.

Explantation of KAMRA Corneal Inlay: 10-Year Occurrence and Visual Outcome Analysis.

Purpose: To evaluate 10 years of KAMRA corneal inlay explantation and associated visual outcomes.

Patients And Methods: Single-site retrospective chart review of 22 cases of AcuFocus KAMRA Inlay (ACI7000PDT) explantation (range 1 week-1 year). Uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), and manifest refraction at 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year post-explantation were reviewed.

Photorefractive Keratectomy Enhancement (PRK) After Small-Incision Lenticule Extraction (SMILE).

Purpose: To determine rates of enhancement and visual prognosis following photorefractive keratectomy (PRK) enhancement of small-incision lenticule extraction (SMILE).

Patients And Methods: This retrospective, single-site study reviewed all cases of primary SMILE at Hoopes Vision in Draper, Utah between March 14, 2017 and April 8, 2022 to identify any cases that required follow-up enhancement. Primary SMILE was performed using Visumax 500 kHz femtosecond laser (Carl Zeiss Meditec, Jena, Germany).

Spatially and optically tailored 3D printing for highly miniaturized and integrated microfluidics.

Traditional 3D printing based on Digital Light Processing Stereolithography (DLP-SL) is unnecessarily limiting as applied to microfluidic device fabrication, especially for high-resolution features. This limitation is due primarily to inherent tradeoffs between layer thickness, exposure time, material strength, and optical penetration that can be impossible to satisfy for microfluidic features. We introduce a generalized 3D printing process that significantly expands the accessible spatially distributed optical dose parameter space to enable the fabrication of much higher resolution 3D components without increasing the resolution of the 3D printer.

Biocompatible PEGDA Resin for 3D Printing.

We report a non-cytotoxic resin compatible with and designed for use in custom high-resolution 3D printers that follow the design approach described in Gong et al., Lab Chip 17, 2899 (2017). The non-cytotoxic resin is based on a poly(ethylene glycol) diacrylate (PEGDA) monomer with avobenzone as the UV absorber instead of 2-nitrophenyl phenyl sulfide (NPS).

Mouse dystrophin enhancer preferentially targets lacZ expression in skeletal and cardiac muscle.

Duchenne muscular dystrophy is a muscle wasting disease that results from a dystrophin deficiency in skeletal and cardiac muscle. Studies concerning the regulatory elements that govern dystrophin gene expression in skeletal and/or cardiac muscle in both mouse and human have identified a promoter and an enhancer located in intron 1. In transgenic mice, the muscle promoter alone targets the expression of a lacZ reporter gene only to the right ventricle of the heart, suggesting the need for other regulatory elements to target skeletal muscle and the rest of the heart.

The mouse dystrophin enhancer is regulated by MyoD, E-box-binding factors, and by the serum response factor.

In vivo studies in the mouse have revealed that the muscle promoter of the mouse dystrophin gene can target the right ventricle of the heart only, suggesting the need for other regulatory elements to target the skeletal muscle as well as other compartments of the heart. In this study we report the identification of the mouse dystrophin gene enhancer that is located approximately 8.5 kilobases downstream from the mouse dystrophin gene muscle promoter.

Comparison of the effects of amikacin and kanamycins A and B on dimyristoylphosphatidylglycerol bilayers. An infrared spectroscopic investigation.

Aminoglycoside antibiotics are very effective against severe Gram-negative infections, but their clinical use is associated with nephrotoxic side-effects. The cascade of events leading to acute renal failure involves an impairment of lysosomal phospholipase activity, which is thought to result from the direct interaction of the drugs with the head group of negative phospholipids. Fourier transform infrared spectroscopy was used to study the effects of three aminoglycosides from the kanamycin family (amikacin and kanamycins A and B) on dimyristoylphosphatidylglycerol (DMPG) bilayers at lysosomal pH.

Cross-interactions between two members of the Dlx family of homeobox-containing genes during zebrafish development.

The Dlx homeobox genes of vertebrates are transcribed in multiple cells of the embryo with overlapping patterns but often with different onsets of expression. Here we describe the interaction between two dlx genes, dlx3 and dlx4, during zebrafish development. The observation that dlx3 expression precedes that of dlx4 in the otic vesicle led us to investigate whether dlx3 had the ability to control expression of dlx4.
