CONTEXT: Arginine, its methylated metabolites and other metabolites related to the urea cycle have been independently associated with cardiovascular risk, but the potential causal meaning of these associations (positive for some metabolites and negative for others) remains elusive due to a lack of studies measuring metabolite changes over time. OBJECTIVE: To examine the association between baseline and 1-year concentrations of urea cycle metabolites and cardiovascular disease in a case-cohort setting...

BACKGROUND & AIM: Statin decreased the risk of decompensation and mortality in veteran patients with cirrhosis due to hepatitis C virus (HCV). Whether this beneficial effect can be extended to cirrhosis in general population or cirrhosis with other causes, such as hepatitis B virus (HBV) infection and alcohol, remains unknown. Statin also decreased the risk of hepatocellular carcinoma (HCC) in patients with chronic HBV and HCV infection. It is unclear whether the effect can be observed in patients already with cirrhosis...

Granulocyte colony-stimulating factor (GCSF) is an option to treat leukopenia in lung transplant recipients. Conflicting evidence exists regarding its effects on acute cellular rejection (ACR). A retrospective, case-cohort study was conducted to assess whether the use of GCSF in lung transplant recipients is associated with an increased incidence of ACR. Patients had to have received at least one dose of GCSF but were excluded if they received GCSF within 30 days prior to transplant or received a lymphocyte-depleting agent within 14 days of GCSF administration...

DNA methylation (DNAm) has been revealed to play a role in various diseases. Here we performed epigenome-wide screening and validation to identify mortality-related DNAm signatures in a general population-based cohort with up to 14 years follow-up. In the discovery panel in a case-cohort approach, 11,063 CpGs reach genome-wide significance (FDR<0.05). 58 CpGs, mapping to 38 well-known disease-related genes and 14 intergenic regions, are confirmed in a validation panel. A mortality risk score based on ten selected CpGs exhibits strong association with all-cause mortality, showing hazard ratios (95% CI) of 2...

The Mediterranean Diet (MD) has been associated with reduced mortality and risk of cardiovascular diseases, but there is only limited evidence on cancer. We investigated the relationship between adherence to MD and risk of postmenopausal breast cancer (and estrogen/progesterone receptor subtypes, ER/PR). In the Netherlands Cohort Study, 62,573 women aged 55-69 years provided information on dietary and lifestyle habits in 1986. Follow-up for cancer incidence until 2007 (20.3 years) consisted of record linkages with the Netherlands Cancer Registry and the Dutch Pathology Registry PALGA...

Cystatin C and beta-2-microglobulin (B2M) are filtration markers associated with adverse outcomes in non-transplant populations, sometimes with stronger associations than for creatinine. We evaluated associations of estimated glomerular filtration rate from cystatin C (eGFRcys ), B2M (eGFRB2M ), and creatinine (eGFRcr ) with cardiovascular outcomes, mortality, and kidney failure in stable kidney transplant recipients using a case-cohort study nested within the Folic Acid for Vascular Outcome Reduction in Transplantation (FAVORIT) Trial...

BACKGROUND AND AIMS: CVD risks associated with coronary artery calcification (CAC) and aortic calcification (AC) are well known, but less is known about other calcified arteries. We aimed to assess the associations of arterial calcification in the breast, splenic, and internal and external iliac arteries with CVD risk factors and mortality. METHODS: We conducted a case-cohort study nested in a cohort of 5196 individuals who self-referred or were referred by a health care provider for whole body computed tomography (CT), including a random subcohort (n = 395) and total and CVD mortality cases (n = 298 and n = 90), who died during a median follow-up of 9...

BACKGROUND: The noninvasive follicular variant of papillary thyroid carcinoma (PTC) has an indolent clinical behavior in comparison with other PTCs, including the invasive follicular variant of papillary thyroid carcinoma (IFVPTC). Recently, the term noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was introduced to emphasize the low biological potential of these tumors. This study compares clinical, cytological, and molecular features of NIFTP and IFVPTC...

Background: During development of cardiovascular disease (CVD), interferon-γ-mediated inflammation accelerates degradation of tryptophan into downstream metabolites. A Mediterranean diet (MedDiet) consisting of a high intake of extra-virgin olive oil (EVOO), nuts, fruits, vegetables, and cereals has been demonstrated to lower the risk of CVD. The longitudinal relation between tryptophan and its downstream metabolites and CVD in the context of a MedDiet is unstudied.Objective: We sought to investigate the relation between metabolites in the tryptophan-kynurenine pathway and CVD in the context of a MedDiet pattern...

INTRODUCTION: Numerous micronutrients have immunomodulatory roles that may influence risk of tuberculosis (TB), but the association between baseline micronutrient deficiencies and incident TB after antiretroviral (ART) initiation in HIV-infected individuals is not well characterized. METHODS: We conducted a case-cohort study (n=332) within a randomized trial comparing three ART regimens in 1571 HIV treatment-naïve adults from nine countries. A subcohort of 30 patients was randomly selected from each country (n=270)...

In the present case-cohort study based on prospective data from Danish women, we aimed to estimate the main effect of polymorphisms in genes known to be involved in the steroid hormone metabolic pathway and xenobiotic metabolism on the risk of developing breast cancer. We also studied a possible effect measure modification between genotypes and levels of serum perfluoroalkylated substances (PFASs) on the risk to breast cancer. We have previously reported a weak association between serum PFASs levels and the risk of breast cancer for this study population of Danish pregnant nulliparous women as well as in a smaller case-control study of Greenlandic women...

BACKGROUND: Despite a call to study the effect of weight gain pattern on development of gestational diabetes mellitus, few studies have correctly adjusted for independent effects of gain after the first trimester. We used a conditional percentile approach to model the independent association between first and second trimester weight-gain trajectories and development of gestational diabetes. METHODS: We sampled women delivering singleton infants from 1998-2010 at Magee-Womens Hospital in Pittsburgh, PA (n=124,590) using a case-cohort design...

Single nucleotide polymorphisms (SNPs) in the interleukin-4 receptor (IL-4R) gene have been identified as having a close association with asthma severity in different populations. In our previous studies, a close association between asthma and a distinctive palm dermatoglyphic pattern was observed; however, the clinical implication and underlying genetic mechanisms of this particular palm pattern have not been clarified. Whether this particular palm pattern is associated with asthma severity and IL-4R SNPs was assessed in the present study...

The case-cohort study design is an effective way to reduce cost of assembling and measuring expensive covariates in large cohort studies. Recently, several weighted estimators were proposed for the case-cohort design when multiple diseases are of interest. However, these existing weighted estimators do not make effective use of the covariate information available in the whole cohort. Furthermore, the auxiliary information for the expensive covariates, which may be available in the studies, cannot be incorporated directly...
