Development and Validation of Algorithms to Identify Individuals With Cutaneous Lupus From Healthcare Databases.

Background: There are no validated methods to identify individuals with cutaneous lupus erythematosus (CLE) from large databases including claims data and electronic health records, severely limiting the study of the epidemiology of this disease.

Objectives: To develop and validate accurate algorithms to identify individuals with CLE from healthcare records.

Methods: Twelve case-finding algorithms were developed based on the International Classification of Diseases (ICD)-10 diagnosis codes, provider specialty, and medication prescription data.

Development of a working core outcome set for cutaneous lupus erythematosus: a practical approach to an urgent unmet need.

Objective: The lack of standardised outcomes and outcome measures for cutaneous lupus erythematosus (CLE) represents a substantial barrier to clinical trial design, comparative analysis and approval of novel investigative treatments. We aimed to develop a working core outcome set (COS) for CLE randomised controlled trials and longitudinal observational studies.

Methods: We conducted a multistage literature review of CLE and SLE studies to generate candidate domains and outcome measures.

Differences in Utilization of Nonvideo Telemedicine Visits for Dermatologic Concerns in Underserved Populations During the COVID-19 Pandemic.

Usage of telemedicine for virtual dermatology care during the COVID-19 pandemic on a national scale is poorly characterized, particularly for nonvideo encounters. We sought to compare utilization of telephone and asynchronous virtual care for dermatologic concerns 3 months before (December 2019-February 2020) and during the pandemic (March-May 2020) across patient populations. A retrospective study was performed using a national claims database with >280 million patients within the COVID-19 Research Database to identify monthly telephone and asynchronous virtual visits by diagnosis, age, income, and patient race/ethnicity.

Towards gender equity in artificial intelligence and machine learning applications in dermatology.

There has been increased excitement around the use of machine learning (ML) and artificial intelligence (AI) in dermatology for the diagnosis of skin cancers and assessment of other dermatologic conditions. As these technologies continue to expand, it is essential to ensure they do not create or widen sex- and gender-based disparities in care. While desirable bias may result from the explicit inclusion of sex or gender in diagnostic criteria of diseases with gender-based differences, undesirable biases can result from usage of datasets with an underrepresentation of certain groups.

Cutaneous lupus erythematosus and cardiovascular disease: current knowledge and insights into pathogenesis.

Multiple autoinflammatory diseases, including psoriasis, psoriatic arthritis, and systemic lupus erythematosus, have been linked to increased risk of cardiovascular disease. Inflammation is known to play a key role in the pathogenesis of atherosclerosis, thus the contribution of systemic immune dysregulation, which characterizes such inflammatory conditions, towards the development of cardiovascular disease has garnered considerable interest. Cutaneous lupus erythematosus (CLE) is a chronic inflammatory skin disease, but risk of cardiovascular disease amongst patients with cutaneous lupus is less well known.

Study on the effectiveness and safety of Foldable Capsular Vitreous Body implantation.

Background: Foldable capsular vitreous body (FCVB) was designed to treat severe retinal detachment. The aim of this study was to evaluate the efficacy and safety of the implantation of foldable capsular vitreous body in 1-year follow-up.

Methods: A retrospective analysis was conducted for 20 patients with severe ocular trauma or silicone oil (SO) dependent eyes underwent vitrectomy and FCVB implantation in a 1-year follow-up.

Gallbladder volvulus in a patient with chronic lymphocytic leukemia treated with laparoscopic cholecystectomy.

Gallbladder volvulus is a rare condition that most commonly occurs in elderly women and often mimics acute cholecystitis in its presentation. This condition is a surgical emergency requiring cholecystectomy as it can lead to gallbladder perforation and bilious peritonitis with high morbidity to the patient. An 85-year-old woman with chronic lymphocytic leukemia presented with acute-onset right upper-quadrant abdominal pain and associated nausea with emesis.

Thinking Fast Increases Framing Effects in Risky Decision Making.

Every day, people face snap decisions when time is a limiting factor. In addition, the way a problem is presented can influence people's choices, which creates what are known as framing effects. In this research, we explored how time pressure interacts with framing effects in risky decision making.

Obesity-related DNA methylation at imprinted genes in human sperm: Results from the TIEGER study.

Background: Epigenetic reprogramming in mammalian gametes resets methylation marks that regulate monoallelic expression of imprinted genes. In males, this involves erasure of the maternal methylation marks and establishment of paternal-specific methylation to appropriately guide normal development. The degree to which exogenous factors influence the fidelity of methylation reprogramming is unknown.

Discovery of the Highly Potent PI3K/mTOR Dual Inhibitor PF-04979064 through Structure-Based Drug Design.

PI3K, AKT, and mTOR are key kinases from PI3K signaling pathway being extensively pursued to treat a variety of cancers in oncology. To search for a structurally differentiated back-up candidate to PF-04691502, which is currently in phase I/II clinical trials for treating solid tumors, a lead optimization effort was carried out with a tricyclic imidazo[1,5]naphthyridine series. Integration of structure-based drug design and physical properties-based optimization yielded a potent and selective PI3K/mTOR dual kinase inhibitor PF-04979064.

Discovery of pyrroloaminopyrazoles as novel PAK inhibitors.

The P21-activated kinases (PAK) are emerging antitumor therapeutic targets. In this paper, we describe the discovery of potent PAK inhibitors guided by structure-based drug design. In addition, the efflux of the pyrrolopyrazole series was effectively reduced by applying multiple medicinal chemistry strategies, leading to a series of PAK inhibitors that are orally active in inhibiting tumor growth in vivo.

Biofunctionalization of titanium with PEG and anti-CD34 for hemocompatibility and stimulated endothelialization.

Thrombosis and restenosis are the main causes of failure of cardiovascular and other blood-contacting biomedical devices. It is recognized that rapid endothelialization is a promising method for preventing these complications. Convincing evidence in vivo has further emerged that the vascular homing of endothelial progenitor cells (EPCs) contributes to rapid endothelial regeneration.

Single limb exercise: pilot study of physiological and functional responses to forced use of the hemiparetic lower extremity.

Purpose: Stroke-related deficits can impede both functional performance and walking tolerance. Individuals with hemiparesis rely on the stronger limb during exercise and functional tasks. The single limb exercise (SLE) intervention was a unique training protocol that focused only on the hemiparetic limb.

Single limb exercise induces femoral artery remodeling and improves blood flow in the hemiparetic leg poststroke.

Background And Purpose: After stroke, individuals have decreased mobility of the hemiparetic leg, which demands less muscle oxygen consumption; thus, blood flow decreases. The purpose of this study was to determine the effect of single limb exercise (SLE) on femoral artery blood flow, diameter, and peak flow velocity in the hemiparetic leg after stroke.

Methods: Twelve individuals (60.
