Vid verksamhetsområdet infektionssjukdomar på Skånes universitetssjukhus planeras en studie kring återfall av Clostridium difficile (nyligen namnbyte till Clodstridoides difficile). Studien ska utreda vilka faktorer som kan vara avgörande för att få fler återfall. Läs mer på https://www.lupop.lu.se/aterfall-av-clostridium-difficle

In this article, we discuss how to discern the causal mechanisms of interest in the sufficient cause model, which pays closer attention to the relationship between the sufficient cause model and the Bradford Hill viewpoints.

The Danish randomized trial studying the effect of mask recommendation (DANMASK-19) was widely discussed in the media. We aimed to analyze this trial from a causal inference perspective. Read the paper at https://academic.oup.com/aje/article/190/10/2231/6279406

In an extension of Mendelian randomization, we leveraged variation in genetic risk for late-onset AD risk to estimate the causal effect of AD on BMI and the earliest ages at which AD-related weight loss (or lower BMI as a proxy) occurs.

We developed and validated a synthetic cohort approach to examine numbers of cardiovascular risk factors (CRFs) and adverse clinical events, including incident cardiovascular disease and all-cause mortality, across the life span from ages 20 years to 90 years.

Smart card data (SCD) allow analyzing mobility at a fine level of detail, despite the remaining challenges such as identifying trip purpose. The use of the SCD may improve the understanding of transit users' travel patterns from precarious settlements areas, where the residents have historically limited access to opportunities and are usually underrepresented in surveys.

Nationwide healthcare registries are potential important real-world data (RWD) sources for assessing drug effectiveness in oncology. However, it is unclear whether registry-derived RWD are suitable for clinical development. Read the paper at https://ascpt.onlinelibrary.wiley.com/doi/10.1002/cpt.2424

Despite progress toward curtailing opioid prescribing, physicians are often slow to adopt new prescribing practices. Using the Abdominal Core Health Quality Collaborative (ACHQC), we aimed to demonstrate the ability of a national, disease-specific, personalized registry to impact opioid prescribing.

The overall accuracy of data held in the New Zealand Trauma Registry (NZTR) is suitable for quality improvement and benchmarking purposes, but more work is needed to improve the accuracy of individual cases, particularly those with head/neck and chest injury.

A well-managed institutional arthroplasty registry, including structured clinical and radiological follow-up assessments, offers the opportunity for high-quality long-term patient and arthroplasty outcome analysis. Such data are not only helpful for analyzing patient outcome and implant survival, but will be increasingly important to justify our daily clinical practice against different stakeholde

We developed standardized QA processes for training, certification and supervision of the MNHR, a multisite research registry. It is expected that these activities, together with ongoing QA processes, will help to further optimize data quality for this protocol.

Our findings suggest that in studies of air pollution and cardiometabolic disease, which use an adjustment strategy with a broad range of register-based socioeconomic variables, there is no effect on risk estimates from subsequent lifestyle adjustment.

Among THR patients value sets based on the same method and perspective, a direct transfer of results across countries could be meaningful. In cases of differences in methods and perspectives among value sets, transfer of value sets across settings would have to consider conversion through crosswalk.
