Age Gene/Environment Susceptibility-Reykjavik-Bone Marrow Adiposity Study

This study is an ongoing population-based study of older men and women in Iceland. It was initiated to examine genetic susceptibility and gene/environment interaction as these contribute to phenotypes common in old age. AGES-Bone Marrow Adiposity Study is sponsored by NIAMS to determine the correlation of marrow adiposity with bone markers and other body composition parameters, such as bone density, body fat mass, visceral and subcutaneous adipose tissue, and fatty muscle infiltration.

AFF

Atypical Femoral Fractures: A Population-Based Study of Risk Factors and Relationship to Bisphosphonate Exposure and Discontinuation)(AFF)

Dr. Doug Bauer, a UCSF General Internist and SFCC member for over 25 years, recently received an NIH grant to study the long-term effects of bisphosphonates, particularly the occurrence of atypical femoral fractures (AFF) which appear to be more common after prolonged bisphosphonate use. Along with UCSF Biostatistician Dennis Black and a Danish collaborator, he plans to analyse longitudinal pharmacy and fracture data from Denmark dating back to 1995. Dr. Bauer hopes to determine how the duration of bisphosphonate use and other risk factors, and discontinuation of bisphosphonates, relates to the risk of AFF in the Danish population.

CALERIE

Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy

This study is a multi-center, parallel-group, randomized, controlled trial that's overall aim is to test the hypothesis that two years of sustained caloric restriction will slow aging and protect against age-related disease processes. UCSF is providing DXA Quality Assurance. BMD at the hip, spine and wrist, as well as composition of the total body are measured for the study, and UCSF is centrally analyzing and archiving all scans.

CARGO

Comprehensive Evaluation of Aging-Related Clinical Outcomes and Geroproteins(CARGO)

Our study harnesses the comprehensive data and statistical power of the Cardiovascular Health Study (CHS) and Dynamics of Health and Body Composition Study (Health ABC) to analyze whether proteins discovered to delay or accelerate aging in the brain, heart, and skeletal muscle are associated with important clinical outcomes: dementia, heart failure, and mobility disability. Data and specimens from the Baltimore Longitudinal Study of Aging (BLSA) will enable us to understand how these proteins vary with age and influence the brain,heart and muscle across the life span. This study will provide a comprehensive picture of the potential of these proteins to give rise to new treatments for major causes of aging-related disability and mortality.

Look AHEAD

Action for Health in Diabetes

This study is a randomized controlled clinical trial that is designed to characterize the impact on several health outcomes of an intervention program designed to produce weight loss. The primary study objective is to determine whether such a program is effective in reducing the number of serious cardiovascular disease events in a cohort of overweight adults with type 2 diabetes. The Coordinating Center serves as the bone density quality assurance group for the study. Hip, spine, and whole body scans are sent to us for quality and technical review and central databasing.

MrOS

Osteoporotic Fractures in Men

This prospective cohort study is designed to examine the extent to which fracture risk is related to bone mass, bone geometry, lifestyle, anthropometric and neuromuscular measures, and fall propensity, as well as to determine how fractures affect quality of life in older men. A total of 5,995 from six US clinical centers were enrolled between March 2000 and April 2002. Participants have been followed since enrollment for incident fractures, falls, prostate cancers, and death. The MrOS study is funded by NIA and NIAMS, currently through June 2012.

MrOS Sleep

Outcomes of Sleep Disorders in Older Men

This study is an ancillary study to the MrOS study. From December 2003 through March 2005, 3,135 MrOS participants were enrolled. Comprehensive and objective assessments of sleep (including overnight in-home polysomnography[PSG], 5-day wrist actigraphy and self-reported measures of sleep quality), adjudication of incident cardiovascular (CVD) events, and other measures including neuromuscular function, bone mineral density, and cognitive function were added to the expansive dataset of the MrOS study. The MrOS Sleep Study is funded by NHLBI. Current funding is through April 2014.

PaTH/PaTH II

PTH and Alendronate in Combination for the Treatment of Osteoporosis

<

Follow-up of PTH and Alendronate in Combination for the Treatment of Osteoporosis PaTH was a 2-year randomized controlled trial of 238 participants at 4 clinical sites to determine if 3 different combination treatments of PTH 1-84 with alendronate increased bone mineral density and bone turnover markers more than alendronate alone. PaTH II was a 1-year observational study designed for a 3rd year of follow-up in women originally randomized into PaTH to assess if MBD continues to increase or is maintained in those treated with PTH followed by a bisphophonate.

PICS

PTH and Ipandronate Combination Study

This is a randomized, placebo-controlled trial in which two combinations of PTH and oral ibandronate (Boniva®) are used to determine the effect on bone markers and bone mass. Forty-four post-menopausal women aged 55+ with low bone density as measured by densitometry were enrolled in this single-center pilot study. Participants will have 24 months of follow-up for clinical exams, imaging, and biomarker measurements. The study includes novel imaging methods including high resolution peripheral CT and MRI X-ray spectroscopy.

ROSTERS

Randomized Order Safety Trial Evaluating Resident Schedules

Dr. Katie Stone is serving as the PI of the Data Coordinating Center (DCC) for the ROSTERS Trial (Randomized Order Safety Trial Evaluating Resident Schedules). ROSTERS is a multi-center randomized crossover trial in six pediatric ICUs staffed by PGY2 and PGY3 residents to compare the effectiveness and safety of a sleep and circadian science-based (SCS) intervention schedule with a traditional schedule that includes frequent shifts of 24 hours or longer. The primary outcome is resident-related preventable adverse events and near misses, and the secondary outcomes are ICU-wide preventable adverse events and near misses and resident neurobehavioral performance and predicted driving safety. The study aims to enroll 300 residents over the course of three years. The first wave of two sites began data collection on November 1, 2013.

Longevity Genomics

Integrative Resource to Develop Translational Strategies to Promote Longevity

Translation of genetic associations into insights that can lead to pharmacological interventions designed to promote healthy aging requires an approach and infrastructure that integrates many sources of information and scientific expertise. We propose the creation of an infrastructure and an integrated data system to enable our team of scientists to develop therapeutic research strategies based on causal connections between molecular traits and healthy aging, and chemicals that target the molecular traits. Therapeutics that can promote healthy aging can have a great impact on the elderly, a rapidly growing subgroup of our population

TOLSURF

Trial of Late Surfactant in Premature Babies

This study is a randomized, multi-center, placebo-controlled trial of late surfactant treatment in infants at high risk of bronchopulmonary dysplasia (BPD). The primary aim of this nationwide trial, funded by NHBLI, is to assess the effect of late doses of surfactant on the occurrence and severity of BPD in ventilated, extremely low gestational age newborns (ELGAN) receiving inhaled nitric oxide (iNO). A cohort of 524 infants will be enrolled and followed for up to 24 months to help investigators better understand whether surfactant will decrease risk of chronic lung disease and improve pulmonary outcome in the ELGAN population.

VEST-PREDICTS

Vest prevention of Early Sudden death Trial (VEST); PREDiction of ICD Therapies Study (PREVENTS)

This study is a multi-center randomized controlled trial and observational follow-up study designed with the goal of improving clinical care for persons at risk of sudden death from heart arrhythmias. Participants include men and women aged 18 years and older with some heart dysfunction after a recent heart attack. The goal of VEST is to determine whether use of a wearable defibrillator vest reduces death in the first 2 months following the heart attack. In PREDICTS, extensive risk stratification testing will be performed and biological samples collected from each study participant with the goal of predicting which persons truly require implantation of a cardioverter-defibrillator device (ICD).
