Animal and human data suggest statins may be protective against developing multiple myeloma; however, findings may be biased by the interrelationship with lipid levels. We investigated the association between statin use and risk of multiple myeloma in a large US population, with an emphasis on accounting for this potential bias. We conducted a case-control study nested within 6 US integrated healthcare systems participating in the National Cancer Institute-funded Cancer Research Network.

Aims: Seven-year surveillance study (2005-2011) to evaluate race/ethnic differences in the trends in rates of severe hypoglycemia (SH) in a population of insured, at-risk adults with diabetes.

Methods: SH events were identified via any primary or principal diagnosis from emergency department or inpatient encounters among African American, Asian, Latino and White adult diabetes patients treated with insulin or secretagogues (Sulfonylureas or Meglitinides), receiving care from integrated healthcare delivery systems across the United States. We calculated age- and sex-standardized annual SH rates and average annual percent change (AAPC) in SH rates.

Prenatal air pollution exposure is frequently estimated using maternal residential location at the time of delivery as a proxy for residence during pregnancy. We describe residential mobility during pregnancy among 19,951 children from the Kaiser Air Pollution and Pediatric Asthma Study, quantify measurement error in spatially resolved estimates of prenatal exposure to mobile source fine particulate matter (PM) due to ignoring this mobility, and simulate the impact of this error on estimates of epidemiologic associations. Two exposure estimates were compared, one calculated using complete residential histories during pregnancy (weighted average based on time spent at each address) and the second calculated using only residence at birth.

Health Services Utilization Among Children With and Without Autism Spectrum Disorders.

J Autism Dev Disord

March 2016

Division of Research, Kaiser Permanente Northern California (KPNC), Oakland, CA, USA.

Using data from multiple health systems (2009-2010) and the largest sample to date, this study compares health services use among youth with and without an autism spectrum disorder (ASD)-including preventive services not previously studied. To examine these differences, we estimated logistic and count data models, controlling for demographic characteristics, comorbid physical health, and mental health conditions. Results indicated that youth with an ASD had greater health care use in many categories, but were less likely to receive important preventive services including flu shots and other vaccinations.

Heart failure (HF) hospitalization length of stay (LOS) has been associated with the risk of subsequent readmission and mortality. We identified 19,927 hospitalized patients with HF who were discharged alive from 2008 to 2011 from 3 Kaiser Permanente regions. In adjusted Cox models using LOS 3 to 4 days as the reference category, shorter LOS was not significantly associated with hospital readmissions.

Mechanical circulatory support for the pediatric patient.

Crit Care Nurs Q

May 2007

Center for Clinical and Outcomes Research, Congenital Heart Surgery Service, Texas Children's Hospital, Houston, Texas 77030, USA.

In adult patients, mechanical circulatory support (MCS) devices are part of the standard of care for heart failure. There are several options available that clinicians may use to provide support for their patients and thus the choice of devices can be tailored to their individual needs. Unfortunately, this is not the case for pediatric patients with heart failure, where the options for MCS modalities are far more limited because of size constraints and regulatory hurdles.
