Rheumatoid arthritis and risk of lung diseases in East Asians and Europeans: Evidence from a Mendelian randomization study

open access: yesSAGE Open Medicine
Background: Rheumatoid arthritis might increase the risk of lung diseases, such as interstitial lung disease and lung cancer. However, the causal relationships remained unclear.

Causal relationship among obesity and body fat distribution and epilepsy subtypes

open access: yesFrontiers in Neurology, 2022
ObjectiveThe observational studies indicate an association between obesity and epilepsy, but it is unclear whether such an association responds to causality.

Smoking and stroke: A mendelian randomization study [PDF]

open access: yesAnnals of Neurology, 2019
We used the Mendelian randomization design to explore the potential causal association of smoking with ischemic stroke and intracerebral hemorrhage using summary statistics data for 34,217 ischemic stroke cases and 404,630 noncases, and 1,545 cases of intracerebral hemorrhage and 1,481 noncases.

Stratification by Smoking Status Reveals an Association of CHRNA5-A3-B4 Genotype with Body Mass Index in Never Smokers [PDF]

open access: yes, 2014
We previously used a single nucleotide polymorphism (SNP) in the CHRNA5-A3-B4 gene cluster associated with heaviness of smoking within smokers to confirm the causal effect of smoking in reducing body mass index (BMI) in a Mendelian randomisation analysis.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Extensions to Mendelian randomization

open access: yes, 2009
The Mendelian randomization approach is concerned with the causal pathway between a gene, an intermediate phenotype and a disease. The aim of the approach is to estimate the causal association between the phenotype and the disease when confounding or ...

Recent Developments in Mendelian Randomization Studies [PDF]

open access: yesCurrent Epidemiology Reports, 2017
Mendelian randomization (MR) is a strategy for evaluating causality in observational epidemiological studies. MR exploits the fact that genotypes are not generally susceptible to reverse causation and confounding, due to their fixed nature and Mendel's First and Second Laws of Inheritance.

Mendelian randomisation for nutritional psychiatry [PDF]

open access: yesThe Lancet Psychiatry, 2020
Nutritional psychiatry is a growing area of research, with several nutritional factors implicated in the cause of psychiatric ill-health. However, nutritional research is highly complex, with multiple potential factors involved, highly confounded exposures and small effect sizes for individual nutrients.

The Multiple Sclerosis Severity Allele rs10191329A and Cognitive Function: A UK Biobank Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The genome‐wide association study of Multiple Sclerosis severity linked the genetic variant rs10191329A to long‐term disability and implicated brain resilience as a determinant of outcome. We hypothesised that rs10191329A might influence cognition in other neurological diseases and healthy controls.

Glucosamine supplementation contributes to reducing the risk of type 2 diabetes: Evidence from Mendelian randomization combined with a meta-analysis

open access: yesJournal of International Medical Research
Objective Observational studies on glucosamine supplementation and type 2 diabetes risk have shown inconsistent results, necessitating the use of Mendelian randomization to clarify the true causal relationship.
