Intraprofessional workplace learning in postgraduate medical education: a scoping review.

Background: Residents need to be trained across the boundaries of their own specialty to prepare them for collaborative practice. Intraprofessional learning (i.e.

Tolerance of clinical uncertainty by geriatric residents: a qualitative study.

Context: With the growing complexity in health care, clinical uncertainty increases, even more so in geriatrics. Intolerance of clinical uncertainty can result in stress, burnout and additional costs. This makes tolerance of clinical uncertainty a highly relevant skill to learn.

Design and evaluation of a clinical competency committee.

Introduction: In postgraduate medical education, group decision-making has emerged as an essential tool to evaluate the clinical progress of residents. Clinical competency committees (CCCs) have been set up to ensure informed decision-making and provide feedback regarding performance of residents. Despite this important task, it remains unclear how CCCs actually function in practice and how their performance should be evaluated.

Do different curriculum aligned selection procedures admit students with different personality profiles to medical school?

Background: Medical schools aim to contribute to a pool of doctors who are ready for a future practice that will be ever-changing requiring collaboration skills and lifelong learning. They adapt their curricula and selection procedures to fulfil this responsibility. This study aims to determine whether two different selection procedures in one medical school, both matching the key characteristics of the subsequent curricula (one traditional, knowledge-based, and one recently designed for self directed learning and focusing on practice), select students with different personality traits as a side-effect.

Selection as a learning experience: an exploratory study.

Introduction: Research on selection for medical school does not explore selection as a learning experience, despite growing attention for the learning effects of assessment in general. Insight in the learning effects allows us to take advantage of selection as an inclusive part of medical students' learning process to become competent professionals. The aims of this study at Radboud University Medical Center, the Netherlands, were 1) to determine whether students have learning experiences in the selection process, and, if so, what experiences; and 2) to understand what students need in order to utilize the learning effects of the selection process at the start of the formal curriculum.

The effects of a non-cognitive versus cognitive admission procedure within cohorts in one medical school.

In medical school selection, non-cognitive performance in particular correlates with performance in clinical practice. It is arguable, therefore, that selection should focus on non-cognitive aspects despite the predictive value of prior cognitive performance for early medical school performance. The aim of this study at Radboud University Medical Center, the Netherlands, is to determine the effects of admitting students through an autonomous non-cognitive procedure on early medical school performance.

Implementing medical teaching policy in university hospitals.

Within the unique and complex settings of university hospitals, it is difficult to implement policy initiatives aimed at developing careers in and improving the quality of academic medical teaching because of the competing domains of medical research and patient care. Factors that influence faculty in making use of teaching policy incentives have remained underexplored. Knowledge of these factors is needed to develop theory on the successful implementation of medical teaching policy in university hospitals.

The effect of curriculum sample selection for medical school.

In the Netherlands, students are admitted to medical school through (1) selection, (2) direct access by high pre-university Grade Point Average (pu-GPA), (3) lottery after being rejected in the selection procedure, or (4) lottery. At Radboud University Medical Center, 2010 was the first year we selected applicants. We designed a procedure based on tasks mimicking the reality of early medical school.

Meta-analysis of 65,734 individuals identifies TSPAN15 and SLC44A2 as two susceptibility loci for venous thromboembolism.

Venous thromboembolism (VTE), the third leading cause of cardiovascular mortality, is a complex thrombotic disorder with environmental and genetic determinants. Although several genetic variants have been found associated with VTE, they explain a minor proportion of VTE risk in cases. We undertook a meta-analysis of genome-wide association studies (GWASs) to identify additional VTE susceptibility genes.

Annexin A5 haplotypes in familial hypercholesterolemia: lack of association with carotid intima-media thickness and cardiovascular disease risk.

Objective: Annexin A5 (ANXA5) has been suggested to possess antiatherogenic properties. We investigated whether ANXA5 genetic variations and plasma ANXA5 levels were associated with carotid atherosclerosis and contributed to cardiovascular disease (CVD) risk in patients with familial hypercholesterolemia (FH).

Methods: We sequenced the promoter region and exon 2 of ANXA5 in 284 FH patients from the ASAP (Atorvastatin versus Simvastatin on Atherosclerosis Progression) trial.

Protein S levels and the risk of venous thrombosis: results from the MEGA case-control study.

In thrombophilic families, protein S deficiency is clearly associated with venous thrombosis. We aimed to determine whether the same holds true in a population-based case-control study (n = 5317). Subjects were regarded protein S deficient when protein S levels were < 2.

Residents provide feedback to their clinical teachers: reflection through dialogue.

Background: Physicians play a crucial role in teaching residents in clinical practice. Feedback on their teaching performance to support this role needs to be provided in a carefully designed and constructive way.

Aims: We investigated an evaluation system for evaluating supervisors and providing formative feedback.

A meta-analysis of thyroid-related traits reveals novel loci and gender-specific differences in the regulation of thyroid function.

Thyroid hormone is essential for normal metabolism and development, and overt abnormalities in thyroid function lead to common endocrine disorders affecting approximately 10% of individuals over their life span. In addition, even mild alterations in thyroid function are associated with weight changes, atrial fibrillation, osteoporosis, and psychiatric disorders. To identify novel variants underlying thyroid function, we performed a large meta-analysis of genome-wide association studies for serum levels of the highly heritable thyroid function markers TSH and FT4, in up to 26,420 and 17,520 euthyroid subjects, respectively.

Estimation of genetic effects in multiple cases family studies using penalized maximum likelihood methodology.

Family studies are often used in genetic research to explore associations between genetic markers and various phenotypes. A commonly used design oversamples families enriched with the disease under study for efficient data collection and estimation. For instance, in a multiple cases family study, families are selected based on the number of affected relatives.

Discovery of common variants associated with low TSH levels and thyroid cancer risk.

To search for sequence variants conferring risk of nonmedullary thyroid cancer, we focused our analysis on 22 SNPs with a P < 5 × 10(-8) in a genome-wide association study on levels of thyroid stimulating hormone (TSH) in 27,758 Icelanders. Of those, rs965513 has previously been shown to associate with thyroid cancer. The remaining 21 SNPs were genotyped in 561 Icelandic individuals with thyroid cancer (cases) and up to 40,013 controls.

Identification of low-frequency variants associated with gout and serum uric acid levels.

We tested 16 million SNPs, identified through whole-genome sequencing of 457 Icelanders, for association with gout and serum uric acid levels. Genotypes were imputed into 41,675 chip-genotyped Icelanders and their relatives, for effective sample sizes of 968 individuals with gout and 15,506 individuals for whom serum uric acid measurements were available. We identified a low-frequency missense variant (c.

Fibrinogen gamma gene 3'-end polymorphisms and risk of venous thromboembolism in the African-American and Caucasian population.

Genetic determinants of venous thromboembolism (VTE) in the African-American population are poorly characterised. It was recently shown that fibrinogen gamma gene (FGG) polymorphisms 10034C>T and 9340T>C influence VTE risk in the Caucasian population. In the African-American population these polymorphisms are common, with allele frequencies above 25%.

Haplotypes of the interleukin-1 receptor antagonist gene, interleukin-1 receptor antagonist mRNA levels and the risk of myocardial infarction.

Background: The overall effect of the major pro-inflammatory cytokine interleukin-1 (IL-1) on coagulation and fibrinolysis is prothrombotic. We recently found that haplotype 5 (H5) of the gene (IL1RN) coding for the interleukin-1 receptor antagonist (IL-1Ra), the natural inhibitor of IL-1, is associated with an increased risk of venous thrombosis. It is unclear whether variations in IL1RN affect the risk of myocardial infarction.

Generalizing Terwilliger's likelihood approach: a new score statistic to test for genetic association.

Background: In this paper, we propose a one degree of freedom test for association between a candidate gene and a binary trait. This method is a generalization of Terwilliger's likelihood ratio statistic and is especially powerful for the situation of one associated haplotype. As an alternative to the likelihood ratio statistic, we derive a score statistic, which has a tractable expression.

Haplotypes of IL1B, IL1RN, IL1R1, and IL1R2 and the risk of venous thrombosis.

Objective: It has been suggested that the overall effect of the major proinflammatory cytokine interleukin-1 (IL-1) on coagulation and fibrinolysis is prothrombotic. The aim of this study was to investigate whether common variations in IL1B, IL1RN, IL1R1, and IL1R2 influence the risk of venous thrombosis.

Methods And Results: In a case-control study on the causes of deep venous thrombosis, the Leiden Thrombophilia Study (LETS), we genotyped 18 single nucleotide polymorphisms (SNPs) in IL1B, IL1RN, IL1R1, and IL1R2, enabling us to tag a total of 25 haplotype groups.

ABO blood group genotypes, plasma von Willebrand factor levels and loading of von Willebrand factor with A and B antigens.

ABO blood group is a genetic determinant of von Willebrand factor (VWF) levels. We investigated the effect of ABO genotypes on VWF and factor VIII (FVIII) levels and on the degree to which VWF is loaded with A- and B-antigens, expressed as normalized ratios, nA-ratio and nB-ratio, respectively, in the Leiden Thrombophilia Study, a large case-control study on venous thrombosis. We found that the ABO locus had an allele-specific, dosage dependent effect on VWF and FVIII levels and on the loading of VWF with A-antigen and B-antigen.

Genetic variation in the fibrinogen gamma gene increases the risk for deep venous thrombosis by reducing plasma fibrinogen gamma' levels.

We investigated the association between haplotypes of fibrinogen alpha (FGA), beta (FGB), and gamma (FGG), total fibrinogen levels, fibrinogen gamma' (gammaA/gamma' plus gamma'/gamma') levels, and risk for deep venous thrombosis. In a population-based case-control study, the Leiden Thrombophilia Study, we typed 15 haplotype-tagging single nucleotide polymorphisms (htSNPs) in this gene cluster. None of these haplotypes was associated with total fibrinogen levels.
