Activating brown adipose tissue (BAT) improves systemic metabolism, making it a promising target for metabolic syndrome. BAT is activated by 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME), which we previously identified to be inversely associated with BMI and which directly improves metabolism in multiple tissues. Here we profile plasma lipidomics from 83 people and test which lipids' association with BMI replicates in a concordant direction using our novel tool ScreenDMT, whose power and validity we demonstrate via mathematical proofs and simulations. We find that the linoleic acid diols 12,13-diHOME and 9,10-diHOME are both replicably inversely associated with BMI and mechanistically activate calcium influx in mouse brown and white adipocytes in vitro, which implicates this signaling pathway and 9,10-diHOME as candidate therapeutic targets. ScreenDMT can be applied to test directional mediation, directional replication, and qualitative interactions, such as identifying biomarkers whose association is shared (replication) or opposite (qualitative interaction) across diverse populations.

Background: This study explores how relative skeletal muscle mass is associated with the development of metabolic dysfunction-associated steatotic liver disease (MASLD) and the remission of baseline MASLD in a community-based population cohort.
Methods: The study included 1,544 participants with an average age of 58 years. All participants underwent baseline and follow-up assessments in 2015 or 2016.

Objective: To evaluate preoperative serum calcium levels and their association with deep infiltrating endometriosis (DIE) in ovarian endometrioma.
Design: A retrospective, observational cohort study.
Participants: A total of 2,557 women who underwent surgery for benign ovarian tumors were initially enrolled.

Introduction: Inflammatory cytokine disturbance is a prominent outcome of immune dysregulation, extensively documented in bipolar disorder (BD). However, observational studies have exhibited inconsistent findings, and the causal relationships between inflammatory factors and BD remain unclear. Hence, this study aimed to uncover the causality between circulating inflammatory cytokines and BD.

Background: Pulmonary Hypertension (PH) is a significant contributor to cardiac mortality in Dilated Cardiomyopathy (DCM) patients. Inflammatory processes and oxidative stress play pivotal roles in the advancement of Pulmonary Hypertension (PH). The Monocyte-to-High-- Density-Lipoprotein Cholesterol Ratio (MHR), a newly identified biomarker indicative of inflammatory and oxidative stress, has not been extensively researched in the context of pulmonary hypertension, especially within the scope of dilated cardiomyopathy.

Background: Ageing in place has been promoted in the Netherlands to encourage optimal functional ability (FA) and independent living among older adults. FA is likely dependent on intrinsic capacity (IC), a composite measure of an individual's mental and physical capacities-and its interaction with the physical environment in which people live. This study aimed to examine the association between IC and FA, as well as to explore how the physical environment may modify this relationship in older adults.
