Biorepository research in children raises numerous ethical questions that are heightened in the pediatric intensive care unit (PICU) setting. We conducted a cross-sectional, interview-based study of 20 adolescent/young adult (A/YA) PICU patients and 75 parents of PICU patients to elucidate perspectives on biorepository research. A/YAs had a positive attitude toward biobanking. In young adults, comprehension was higher for knowledge of a choice to withdraw and participate in the research and lower for purpose, procedures, risks, and benefits of participation...

To enable clinical and translational research, academic medical centers increasingly implement biospecimen information management systems. At our institution, one laboratory successfully implemented a multi-system solution that enabled collection and reporting of specimen- and aliquot-level data. The objective of this study was to assess the solution against the laboratory's requirements and with respect to support of best practices for biospecimen information management systems defined by the International Society for Biological and Environmental Repositories (ISBER)...

BACKGROUND: Polycystic ovary syndrome (PCOS) affects 5%-15% of women and is the most common cause of hirsutism. Data on the time-course of improvement to suppressive therapy and predictors of that response in PCOS are lacking. The objectives of our study are to determine the long-term response and identify predictors of response in PCOS women treated with suppressive therapy, including spironolactone (SPL) + oral contraceptives (OCs). MATERIALS AND METHODS: Retrospective cross-sectional analysis of 200 women with PCOS (1990 NIH criteria) treated with suppressive therapy in general, and a subgroup of 138 subjects treated with OCP+SPL who had been prospectively included in a biorepository...

Health systems are stewards of patient electronic health record (EHR) data with extraordinarily rich depth and breadth, reflecting thousands of diagnoses and exposures. Measures of genomic variation integrated with EHRs offer a potential strategy to accurately stratify patients for risk profiling and discover new relationships between diagnoses and genomes. The objective of this study was to evaluate whether polygenic risk scores (PRS) for common cancers are associated with multiple phenotypes in a phenome-wide association study (PheWAS) conducted in 28,260 unrelated, genotyped patients of recent European ancestry who consented to participate in the Michigan Genomics Initiative, a longitudinal biorepository effort within Michigan Medicine...

Background: African-American women, especially in the southern United States, are underrepresented in cancer genetics research. A study was designed to address this issue by investigating the germline mutation rate in African-American women in Arkansas with a personal and/or family history of breast cancer. Women were tested for these mutations using a large panel of breast cancer susceptibility genes. In this analysis, we discuss the challenges encountered in recruiting African-American women from an existing biorepository to participate in this study...

BACKGROUND: In medical intensive care unit (MICU) patients, the predictors of post-discharge sleep disturbance and functional disability are poorly understood. ICU delirium is a risk factor with a plausible link to sleep disturbance and disability. This study evaluated the prevalence of self-reported post-ICU sleep disturbance and increased functional disability, and their association with MICU delirium and other ICU factors. METHODS: This was an observational cohort study of MICU patients enrolled in a biorepository and assessed upon MICU admission by demographics, comorbidities, and baseline characteristics...

INTRODUCTION: We assessed the radiosensitivity of lung metastases based on primary histology using a validated gene signature and model lung metastases for the genomically adjusted radiation dose (GARD). METHODS: Tissue samples were identified from our prospective observational protocol. The radiosensitivity index (RSI) 10 gene assay was run on samples and calculated alongside GARD using the previously published algorithms. A cohort of 105 patients with 137 lung metastases treated with SBRT at our institution was used for clinical correlation...

Africa was previously insufficiently represented in the emerging discipline of biobanking despite commendable early efforts. However, with the Human, Heredity, and Health in Africa (H3Africa) initiative, biorepository science has been bolstered, regional biobanks are springing up, and awareness about biobanks is growing on the continent. The Stroke Investigative Research and Educational Network (SIREN) project is a transnational, multicenter, hospital and community-based study involving over 3000 cases and 3000 controls recruited from 16 sites in Ghana and Nigeria...

Precision medicine is being enabled in high-income countries by the growing availability of health data, increasing knowledge of the genetic determinants of disease and variation in response to treatment (pharmacogenomics), and the decreasing costs of data generation, which promote routine application of genomic technologies in the health sector. However, there is uncertainty about the feasibility of applying precision medicine approaches in low- and middle-income countries, due to the lack of population-specific knowledge, skills, and resources...

Aim: PANcreatic-DERived factor (PANDER, FAM3B) is a novel hormone that regulates glucose levels via interaction with both the endocrine pancreas and liver. Prior studies examining PANDER were primarily conducted in murine models or in vitro but little is known regarding the circulating concentration of PANDER in humans, especially with regard to the association of type 2 diabetes (T2D) or overall glycemic regulation. To address this limitation, we performed a cross-sectional analysis of circulating serum PANDER concentration in association with other hormones that serve as either markers of insulin resistance (insulin and adiponectin) or to metabolic parameters of glycemic control such as fasting HbA1c and blood glucose (FBG)...

BACKGROUND: There is emerging evidence that there are shared genetic, environmental and developmental risk factors in psychiatry, that cut across traditional diagnostic boundaries. With this background, the Discovery biology of neuropsychiatric syndromes (DBNS) proposes to recruit patients from five different syndromes (schizophrenia, bipolar disorder, obsessive compulsive disorder, Alzheimer's dementia and substance use disorders), identify those with multiple affected relatives, and invite these families to participate in this study...

Policy Points: While most scholarship regarding the US Public Health Service's STD experiments in Guatemala during the 1940s has focused on the intentional exposure experiments, secondary research was also conducted on biospecimens collected from these subjects. These biospecimen experiments continued after the Guatemala grant ended, and the specimens were used in conjunction with those from the Tuskegee syphilis experiments for ongoing research. We argue there should be a public accounting of whether there are still biospecimens from the Guatemala and Tuskegee experiments held in US government biorepositories today...

BACKGROUND & AIMS: Genetic factors are believed to affect risk for irritable bowel syndrome (IBS), but there have been no sufficiently powered and adequately sized studies. To identify DNA variants associated with IBS risk, we performed a genome-wide association study (GWAS) of the large UK Biobank population-based cohort, which includes genotype and health data from 500,000 participants. METHODS: We studied 7,287,191 high-quality single nucleotide polymorphisms in individuals who self-reported a doctor's diagnosis of IBS (cases; n = 9576) compared to the remainder of the cohort (controls; n = 336,499) (mean age of study subjects, 40-69 years)...

The National Institute of Allergy and Infectious Diseases (NIAID) AIDS Clinical Trials Group (ACTG) stores specimens from its clinical trials in a biorepository and permits the use of these specimens for nonprotocol exploratory studies, once the studies for the original protocol are concluded. We sought to assess the comparability of the data generated from real-time HIV-1 RNA testing during two clinical trials with the data generated from the retesting of different aliquots of the same samples after years of storage at -80°C...

INTRODUCTION: Prevention of multidrug-resistant organism (MDRO) infections, such as those caused by methicillin-resistant Staphylococcus aureus , vancomycin-resistant enterococci, fluoroquinolone-resistant Gram-negative bacteria and Clostridium difficile is crucial. Evidence suggests that dietary fibre increases gut microbial diversity, which may help prevent colonisation and subsequent infection by MDROs. The aim of the Winning the War on Antibiotic Resistance (WARRIOR) project is to examine associations of dietary fibre consumption with the composition of the gut microbiota and gut colonisation by MDROs...

BACKGROUND: Ovarian carcinoma is the most lethal gynecological malignancy due to early dissemination and acquired resistance to platinum-based chemotherapy. Reliable markers that are independent and complementary to clinical parameters are needed to improve the management of patients with this disease. The Canadian Ovarian Experimental Unified Resource (COEUR) provides researchers with biological material and associated clinical data to conduct biomarker validation studies. Using standards defined by the Canadian Tissue Repository Network (CTRNet), we have previously demonstrated the quality of the biological material from this resource...
