There has been a fear that the swine flu vaccine, Pandemrix, would increase the risk of autoimmune diseases other than narcolepsy. However, a new study of children from Sweden and Finland shows that the vaccine increased neither the risk of developing autoantibodies against insulin-producing beta cells nor the occurrence of type 1 diabetes. “On the contrary, the risk was reduced among vaccinated c

Researchers at Lund University in Sweden have found that the presence of death receptors in the blood can be used to directly measure the risk of developing cardiovascular diseases and type 2 diabetes. “We see that people with known risk factors such as high blood sugar and high blood fats also have heightened death receptor levels”, says Professor Jan Nilsson who led the study. Death receptors ar

A completely new classification of diabetes which also predicts the risk of serious complications and provides treatment suggestions. We are now seeing the first results of ANDIS – a study covering all newly diagnosed diabetics in southern Sweden — published in The Lancet Diabetes & Endocrinology. The major difference from today’s classification is that type 2 diabetes actually consists of several

1) We found 15 national/regional registries of congenital heart disease worldwide. 2) Registry coverage ranged from 25 to 100% of all eligible cases. 3) The best registries contain demographic, clinical, physical, and laboratory data. 4) Regular verification is essential for quality data and valid statistical findings.

Quantitative bias analyses allow researchers to adjust for uncontrolled confounding, given specification of certain bias parameters. When researchers are concerned about unknown confounders, plausible values for these bias parameters will be difficult to specify.

The benefits of using data from national registers as endpoints in epidemiological studies include faster, less resource-intensive access to nationwide data and considerably lower loss to follow-up, compared to manual data collection in a limited geographical area.

This first publication of the Austrian Society of Esophageal Surgery shows that the outcome of esophageal surgery for cancer in Austria compares well with that of renowned international centers. However, a more comprehensive approach including as many national centers as possible will improve outcome research, offer quality management, and improve patient safety.

Parameters representing adjusted treatment effects may be defined marginally or conditionally on covariates. The choice between a marginal or covariate-conditional parameter should be driven by the study question. However, an unappreciated benefit of marginal estimators is a reduction in susceptibility to finite-sample bias relative to the unpenalized maximum likelihood estimator of the covariate-

Monitoring survival in cancer is a common concern for patients, physicians, and public health researchers. The traditional cohort approach for monitoring cancer prognosis has a timeliness problem. In this paper, we propose a survivorship-period-cohort (SPC) model for examining the effects of survivorship, period, and year-of-diagnosis cohort on cancer prognosis and for predicting future trends in

Life-course epidemiology is useful for describing and analyzing complex etiological mechanisms for disease development, but existing statistical methods are essentially confirmatory, because they rely on a priori model specification.

In the causal mediation framework, several parametric-regression–based approaches have been introduced in the last decade for estimating natural direct and indirect effects. For a binary outcome, a number of proposed estimators use a logistic model and rely on specific assumptions or approximations that may be delicate or not easy to verify in practice.

Confounding by comorbidities is of concern in many epidemiological studies. To take this into account a common strategy is to calculate each participant’s Charlson Comorbidity Index (CCI) and use this for adjustment in regression analyses. Various CCI adjustment strategies are possible, and it is unclear, which is preferable. Read the paper at https://link.springer.com/article/10.1007%2Fs10654-021

A key assumption of Mendelian randomization (MR) analysis is that there is no association between the genetic variants used as instruments and the outcome other than through the exposure of interest. One way in which this assumption can be violated is through population stratification, which can introduce confounding of the relationship between the genetic variants and the outcome and so induce an
