Accelerating health system innovation: principles and practices from the Duke Institute for Health Innovation.

The Duke Institute for Health Innovation (DIHI) was launched in 2013. Frontline staff members submit proposals for innovation projects that align with strategic priorities set by organizational leadership. Funded projects receive operational and technical support from institute staff members and a transdisciplinary network of collaborators to develop and implement solutions as part of routine clinical care, ranging from machine learning algorithms to mobile applications.

Associations between body condition, rumen fill, diarrhoea and lameness and ruminal acidosis in Australian dairy herds.

Aims: To investigate associations between ruminal acidosis and body condition score (BCS), prevalence of poor rumen fill, diarrhoea and lameness in dairy cows in New South Wales and Victoria, Australia.

Methods: This was a cross-sectional study conducted in 100 dairy herds in five regions of Australia. Feeding practices, diets and management practices of herds were assessed.

Validation of an LC-MS/MS assay for detecting relevant disaccharides from keratan sulfate as a biomarker for Morquio A syndrome.

Background: Mucopolysaccharidosis IVA (MPS IVA, Morquio A syndrome) is an inherited lysosomal storage disease caused by deficiency of N-acetylgalactosamine-6-sulfatase (GALNS), an enzyme required for stepwise degradation of keratan sulfate (KS). We have developed a selective, sensitive, accurate and precise LC-MS/MS assay for the KS-derived disaccharides Galβ1-4GlcNAc(6S) and Gal(6S)β1-4GlcNAc(6S) in human urine and plasma using keratanase II digestion.

Results: Mean accuracy was 96-106% in urine and 97-108% in plasma.

Training the next generation of physician-executives: an innovative residency pathway in management and leadership.

The rapidly changing field of medicine demands that future physician-leaders excel not only in clinical medicine but also in the management of complex health care enterprises. However, many physicians have become leaders "by accident," and the active cultivation of future leaders is required. Addressing this need will require multiple approaches, targeting trainees at various stages of their careers, such as degree-granting programs, residency and fellowship training, and career and leadership development programs.

Carryover effects of potassium supplementation on calcium homeostasis in dairy cows at parturition.

The purpose of this study was to test whether supplementation with K improves bone mineral density (BMD) in older cows so that by parturition their bone is better able to mobilize Ca. Twenty-four Holstein Friesian cows (6 mo pregnant, lactating, and in their third or later lactation) were allocated to 2 equal groups and individually fed twice daily a total diet comprising low K oaten hay plus a pelleted concentrate fortified with or without K(2)CO(3) to achieve 3.12% K/kg of DM in the total diet of the K-supplemented (KS) cows compared with 1.
