Self-Trephination in Cranial Excoriation Disorder.

Background And Importance: Trephination is a procedure in which a small hole is made in the skull. Rare cases of self-trephination by individuals seeking medical benefit have been reported. Excoriation disorder is a compulsive skin-picking condition in which an individual self-inflicts cutaneous lesions.

Parental Education for the Prevention of Plagiocephaly.

Introduction: The American Academy of Pediatrics Back-to-Sleep Campaign significantly reduced infant mortality from sudden infant death syndrome. As a result of prolonged supine positioning, the incidence of deformational plagiocephaly has also risen 5-fold since its adoption. We aimed to improve the current educational paradigm for new parents with the goal of reducing the incidence of plagiocephaly within the confines of the Back-to-Sleep Campaign.

Heterozygous FOXJ1 Mutations Cause Incomplete Ependymal Cell Differentiation and Communicating Hydrocephalus.

Heterozygous mutations affecting FOXJ1, a transcription factor governing multiciliated cell development, have been associated with obstructive hydrocephalus in humans. However, factors that disrupt multiciliated ependymal cell function often cause communicating hydrocephalus, raising questions about whether FOXJ1 mutations cause hydrocephalus primarily by blocking cerebrospinal fluid (CSF) flow or by different mechanisms. Here, we show that heterozygous FOXJ1 mutations are also associated with communicating hydrocephalus in humans and cause communicating hydrocephalus in mice.

Chronic Glucocorticoid Exposure Induced an S1PR2-RORγ Axis to Enhance Hepatic Gluconeogenesis in Male Mice.

It is well established that chronic glucocorticoid exposure causes hyperglycemia. While glucocorticoid receptor (GR) stimulates hepatic gluconeogenic gene transcription, additional mechanisms are activated by chronic glucocorticoid exposure to enhance gluconeogenesis. We found that chronic glucocorticoid treatment activated sphingosine-1-phosphate (S1P)-mediated signaling.

Transcriptional coactivation by EHMT2 restricts glucocorticoid-induced insulin resistance in a study with male mice.

The classical dogma of glucocorticoid-induced insulin resistance is that it is caused by the transcriptional activation of hepatic gluconeogenic and insulin resistance genes by the glucocorticoid receptor (GR). Here, we find that glucocorticoids also stimulate the expression of insulin-sensitizing genes, such as Irs2. The transcriptional coregulator EHMT2 can serve as a transcriptional coactivator or a corepressor.

Distance Learning and Spaced Review to Complement Dermoscopy Training for Primary Care.

Background: Dermoscopy aids in skin cancer identification. For family physicians who use dermoscopy, there is higher sensitivity for melanoma detection than naked-eye examination. There is a shortage of dermoscopy training for primary care providers.

Public R&D Investments and Private-sector Patenting: Evidence from NIH Funding Rules.

We quantify the impact of scientific grant funding at the National Institutes of Health (NIH) on patenting by pharmaceutical and biotechnology firms. Our paper makes two contributions. First, we use newly constructed bibliometric data to develop a method for flexibly linking specific grant expenditures to private-sector innovations.

The applied value of public investments in biomedical research.

Scientists and policy-makers have long argued that public investments in science have practical applications. Using data on patents linked to U.S.

The Forensic Lens: Bringing Elder Neglect Into Focus in the Emergency Department.

We present 2 case studies of older patients who were brought to the emergency department (ED) in severely debilitated states. Both presented with severe malnutrition, contractures, and decubitus ulcers, and were nonverbal, with histories of dementia and end-stage disease. Their primary caregivers, adult children, were uncooperative with Adult Protective Services and disregarded treatment recommendations.

Research funding. Big names or big ideas: do peer-review panels select the best science proposals?

This paper examines the success of peer-review panels in predicting the future quality of proposed research. We construct new data to track publication, citation, and patenting outcomes associated with more than 130,000 research project (R01) grants funded by the U.S.
