Gene Expression Correlates with Disability and Pain Intensity in Patients with Chronic Low Back Pain and Modic Changes in a Sex-Specific Manner.

Chronic low back pain (cLBP) lacks clear physiological explanations, and the treatment options are of limited effect. We aimed to elucidate the underlying biology of cLBP in a subgroup of patients with Modic changes type I (suggestive of inflammatory vertebral bone marrow lesions) by correlating gene expression in blood with patient-reported outcomes on disability and pain intensity and explore sex differences. Patients were included from the placebo group of a clinical study on patients with cLBP and Modic changes.

Genomics yields biological and phenotypic insights into bipolar disorder.

Bipolar disorder is a leading contributor to the global burden of disease. Despite high heritability (60-80%), the majority of the underlying genetic determinants remain unknown. We analysed data from participants of European, East Asian, African American and Latino ancestries (n = 158,036 cases with bipolar disorder, 2.

Insights into Chronic Low Back Pain Etiology: Population-based genome-wide Association Study Identifies 18 Risk Loci.

Study Design: Genome-wide association study (GWAS) meta-analysis with downstream analyses.

Objective: To explore the genetic architecture of chronic low back pain (cLBP) and identify underlying biological mechanisms that contribute to its development.

Summary Of Background Data: Chronic low back pain is prevalent and debilitating, with many cases having no identifiable biological cause.

Life-style and metabolic factors do not affect risk for glioma: a prospective population-based study (The Cohort of Norway).

Background: The identification of modifiable risk factors for intracranial glioma remains a significant challenge. While lifestyle factors and metabolic syndrome are well-established risk factors for various other cancers, their association with glioma risk remains unclear.

Objectives: This study aims to conduct a comprehensive analysis of lifestyle factors and metabolic factors in relation to glioma risk.

Dependence of brain-tissue R on MRI field strength.

Purpose: To quantify T relaxation in the brain at 3 T and 7 T to study its field dependence and correlation with iron content, and to investigate whether iron can be separated from other sources of T relaxation based on this field dependence.

Methods: Nine subjects were scanned at both field strengths with the same acquisition technique, which used multiple gradient-echo sampling of a spin echo. This allowed for separation of T relaxation from static dephasing by B field inhomogeneities and the effects of radiofrequency refocusing imperfections.
