Targeted metabolomics for early pregnancy prediction of gestational diabetes mellitus

This study will apply a targeted metabolomics approach to the prediction of gestational diabetes from a single blood sample collected in the first trimester of pregnancy and stored for the Research Program on Genes, Environment and Health pregnancy cohort study, which recruited 24,000 pregnant participants during early pregnancy through delivery within Kaiser Permanente Northern California. This large racially and ethnically diverse pregnancy cohort, with stored biospecimens, and clinical data and perinatal health outcomes from electronic health records, provides an excellent opportunity to conduct a nested case-control study among women without prior diabetes to identify a metabolite profile predicting subsequent gestational diabetes diagnosis during mid-gestation. This study will involve a specialized targeted metabolomics approach that can reveal risk of gestational diabetes significantly sooner than conventional tests.

Nationwide Utilization of Danish Government Electronic Letter System for Increasing InFLUenza Vaccine Uptake (NUDGE-FLU)

NUDGE-FLU was a nationwide, pragmatic, registry-based, cluster-randomized implementation trial during the 2022-23 influenza season in Denmark. NUDGE FLU randomized >960,000 Danish citizens aged 65 years or older to usual care or 9 different behaviorally informed electronic letters (9:1:1:1:1:1:1:1:1:1) promoting influenza vaccination. Letters explaining the potential cardiovascular benefits of influenza vaccination demonstrated a modest but significant improvement in vaccination uptake, a finding which was particularly pronounced in patients without vaccination in the prior influenza season, potentially indicating the ability to nudge a vaccine hesitant group.

Calculator for Length of Use of Bisphosphonates (CLUB)

Despite the wide availability of bisphosphonate drugs that reduce fracture risk, treatment rates have fallen, attributable to concerns for atypical femoral fractures and osteonecrosis of the jaw. While risk/benefit ratios of bisphosphonate treatment for osteoporosis remain highly favorable in the first 3-5 years, fracture-prevention benefit wanes with longer treatment and risks of side effects increases. This study will estimate the risks/benefits of bisphosphonate drug holidays; determine the cost effectiveness of continuing vs discontinuing a bisphosphonate after 3 years; and develop and validate a risk factor calculator to guide decisions about length of bisphosphonate use.

Effect of reproductive history on longitudinal change in cardiac, vascular, and lipid parameters

The NHLBI NGHS enrolled 871 girls (50% Black and 50% white) in 1987 at age 9 or 10 and examined them up to 17 times, to age 27. This resulted in 7 echocardiogram reports from ages 20-27, multiple saved samples, and reproductive history questionnaires. We will conduct detailed lipoprotein sizing and functionality assessments from stored and new samples, cardiovascular imaging, and repeat echocardiograms at median age 46. Our aims are to determine the specific lipoprotein particle size distribution and function changes which occur from before to short- and long-term post-pregnancy; determine whether pregnancy-related cardiac adaptations result in long-term alterations in cardiac structure and function, thereby increasing CVD risk for women in their forties; and to test whether parity increases cardiovascular risk independently of socioeconomic status in Black and white women.

Outpatient Worsening Heart Failure in an Integrated Health Care Delivery System: An Innovative Approach to Characterizing a Novel Clinical Entity

While the Affordable Care Act-mandated Hospital Readmission Reduction Program launched in 2012 has modestly reduced readmissions, an unintended consequence has been the shift of a significant fraction of heart failure (HF)-related care to the outpatient setting. However, little is known about the epidemiology, clinical profile, treatment patterns, and/or outcomes of outpatient worsening HF (WHF). To address these critical knowledge gaps, we propose (1) to systematically describe the contemporary epidemiology, clinical characteristics, treatment patterns, and outcomes associated with outpatient WHF and (2) to evaluate the impact of an episode of outpatient WHF on generic and disease-specific HRQOL in the context of a fully integrated health care delivery system.

Disparities in Residual Risk in Patients Receiving Statins for Primary or Secondary Prevention at an Integrated Health Care Delivery System

Patients with risk factors for or established atherosclerotic cardiovascular disease (ASCVD) remain at high risk for first-time or recurrent nonfatal and fatal events, despite guideline-directed medical therapy for primary and secondary prevention. In fact, even among patients who are appropriately treated with lipid-lowering therapies and have an LDL-C that is at goal and in line with current guideline recommendations, substantial residual risk persists. There is now a considerable body of evidence to suggest that plasma triglycerides contribute to residual risk and play a causal role in atherogenesis and ASCVD risk. Furthermore, older adults, women, and nonwhite participants may have a disproportionately different prevalence of elevated triglyceride levels and be at incrementally greater risk of recurrent ASCVD events. Given the public health implications, it is important to better understand the extent of age-, gender-, and ethnicity/race-related disparities in residual risk.

Improving Stroke Prevention for High-risk Atrial Fibrillation by Discharge Redesign Using Electronic Clinical Decision Support

This is a retrospective cohort study to describe the effect of adding direct oral anticoagulants to the Kaiser Permanente formulary on overall rates of oral anticoagulant initiation at the time of discharge for emergency department and inpatients with high-risk non-valvular atrial fibrillation or flutter across 21 medical centers from 2010-2017. The results of this study will inform the design of an electronic clinical decision support tool to aid emergency physicians and hospitalists in the comprehensive management of patients with atrial fibrillation or flutter. The tool will include evidence-based guidance on rate reduction, cardioversion, and stroke prevention. The tool will be evaluated in a pilot study at three large Kaiser Permanente medical centers in Northern California. If the tool improves outcomes of patient care, expansion of tool access across the region for further study will be considered.

How Fast is Fast Enough? Assessing Door-to-Needle Times and Outcomes of Stroke Patients Receiving Acute Thrombolysis Therapy Under the Kaiser Permanente Northern California Stroke EXPRESS Program

With stroke treatment, there is a general belief that “time is brain.” However, there has been no published data examining specifically the association between door-to-needle times for acute treatment with intravenous alteplase in stroke patients and 90-day outcomes. In 2016, the Kaiser Permanente Northern California Stroke EXPRESS program rolled out at all 21 primary stroke centers with significant improvement in door-to-needle times. This study has two major aims: 1) to determine if there is an association between door-to-needle times and mortality at discharge and at 90-day post-treatment in patients who receive acute thrombolysis treatment with intravenous alteplase at Kaiser Permanente Northern California, and 2) to determine if there is an association between door-to-needle times and 90-day favorable functional outcome (defined as mRS 0-2) in patients who receive acute thrombolysis treatment with intravenous alteplase at Kaiser Permanente Northern California.

Network and Infrastructure Support for Development of Interdisciplinary Aging Research

For adults aged 40 to 75 years, randomized trials provide conclusive evidence that statins reduce the risk of initial and secondary cardiovascular disease (CVD) events. However, there is limited evidence that statins reduce CVD events in individuals over the age of 75 who do not have clinically recognized CVD, and older adults may be at greater risk of adverse effects from statins. It is important for statin treatment of this age group to be rigorously evaluated in a randomized clinical trial. The primary objective of this pilot study is to understand recent patterns of statin use and the feasibility of conducting a possible trial on the net effects of statins in adults more than 75 years old without clinical CVD.

Predicting Readmission After Stroke Study (PRESS)

Hospital readmissions are a tremendous burden on patients, their families, and the health care system. In 2008, the Centers for Medicare and Medicaid Services began publicly reporting hospital-level, risk-standardized, 30-day readmission and mortality rates for acute myocardial infarction and heart failure. Stroke survivors also have high risk of new illness, worsened known diseases, functional decline, and a high death rate. Readmission rates of 20 to 27 percent within one year have been reported. A systematic review of predictors of hospital readmission after stroke yielded no risk-standardized models for comparing hospital readmission performance or predicting readmission risk after stroke. This project aims to create a risk-adjusted predictive model for re-hospitalization after ischemic stroke using retrospectively and prospectively collected patient-level and hospital-level data, and to validate the model retrospectively and prospectively.

Multiethnic Study of Breast Arterial Calcium Gradation and CVD

Specific study aims are: 1) To establish a multi-ethnic cohort between the ages of 60 and 79 years with equal representation of white, African-American, Asian and Hispanic/Latina women. All participants will be recruited at the time of their regular screening mammography and will be free of clinical CVD at baseline. A new, validated densitometry method will be used to estimate BAC mass (in milligrams) using digital mammograms; 2) To document race/ethnic variation in BAC mass and to examine associations of BAC mass with sociodemographic background, family history of CVD, traditional and novel CVD risk factors, reproductive health factors, psychosocial factors, selected mineral metabolism factors, selected medication use (statins and nitrogen-containing bisphosphonates), breast size and sleep-related factors; and 3) To elucidate the role of BAC mass in the prediction of coronary heart disease (CHD), cerebrovascular disease, heart failure, peripheral vascular disease and total CVD and to determine whether adding BAC mass to prediction models based on traditional risk factors improves classification of risk for total CVD and its components. Accomplishing these aims will provide novel insights into the utility of BAC mass as a screening tool to assess CVD risk.

Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial (CREST-2)

Carotid revascularization for primary prevention of stroke (CREST-2) is two independent multi-center, randomized controlled trials of carotid revascularization and intensive medical management versus medical management alone in patients with asymptomatic high-grade carotid stenosis. One trial will randomize patients in a 1-to-1 ratio to endarterectomy versus no endarterectomy, and another will randomize patients in a 1-to-1 ratio to carotid stenting with embolic protection versus no stenting. Medical management will be uniform for all randomized treatment groups and will be centrally directed. The purpose of this trial is to determine the best way to prevent strokes in people who have a high amount of blockage of their carotid artery but no stroke symptoms related to that blockage.

Femur Fracture Outcomes Associated with Bisphosphonate Use

In clinical practice, bisphosphonate drugs are considered one of the main therapies for osteoporosis, based on strong clinical evidence of significant reduction in risk of hip, vertebral and non-vertebral fractures during the first 3-5 years of therapy. However, concerns have emerged regarding uncommon long term adverse outcomes in patients treated beyond this period. This study proposes to fill an important knowledge gap by examining the risk of atypical femur fracture in women who receive bisphosphonate treatment for less than 3 years compared to women who continue treatment beyond 3 years and to examine the association of long term continuation of bisphosphonate therapy and subsequent risk of atypical femur fracture.
