Lean Six Sigma, in various forms, has been used widely in many Fortune 500 companies. Motorola, General Electric, Sony, American Express, and Bechtel all use Six Sigma to improve quality and performance. While the impact of this methodology has been documented extensively by the press in manufacturing and transactional settings, less evidence is available regarding its utility in health care environments. Mount Sinai Medical Center initiated a Six Sigma program in 2000 to determine its applicability and value in a large academic medical center. This article discusses Mount Sinai Medical Center's experience adapting this methodology to improve both patient care and business processes and outcomes. We present an overview of Six Sigma, and offer examples of projects undertaken using this data-driven approach to performance improvement. Lastly, the article provides insights and lessons learned regarding this organization-wide experience.

Article Synopsis
- The study aimed to identify the relationship between presynaptic growth-associated protein 43 (GAP-43) levels in cerebrospinal fluid (CSF) and various Alzheimer disease (AD) biomarkers, using a retrospective analysis of the AD Neuroimaging Initiative cohort.
- Results showed that participants with Aβ-positive status had higher GAP-43 levels regardless of cognitive impairment, and those with high levels of GAP-43 experienced worsened brain metabolism, atrophy, and cognitive decline over time.
- Furthermore, Aβ-positive individuals with elevated GAP-43 levels were at significantly higher risk of progressing to AD dementia, indicating a potential role for GAP-43 as a predictor for AD progression.

Medical research and clinical practice are currently being redefined by the constantly increasing amounts of multiscale patient data. New methods are needed to translate them into knowledge that is applicable in healthcare. Multiscale modeling has emerged as a way to describe systems that are the source of experimental data.

Objective: A single course of antenatal corticosteroids (ACS) is associated with a reduction in respiratory distress syndrome and neonatal death. Multiple Courses of Antenatal Corticosteroids Study (MACS), a study involving 1858 women, was a multicentre randomized placebo-controlled trial of multiple courses of ACS, given every 14 days until 33+6 weeks or birth, whichever came first. The primary outcome of the study, a composite of neonatal mortality and morbidity, was similar for the multiple ACS and placebo groups (12.
