Ion mobility (IM) is a gas phase separation strategy that can either supplement or serve as a high-throughput alternative to liquid chromatography (LC) in shotgun lipidomics. Incorporating the IM dimension in untargeted lipidomics workflows can help resolve isomeric lipids, and the collision cross section (CCS) values obtained from the IM measurements can provide an additional molecular descriptor to increase lipid identification confidence. This chapter provides a broad overview of an untargeted ion mobility-mass spectrometry (IM-MS) workflow using a commercial drift tube ion mobility-quadrupole-time-of-flight mass spectrometer (IM-QTOF) for high confidence lipidomics.

Objective: To assess the simultaneity of risk behaviors for chronic non-communicable diseases and their association with individual and contextual characteristics in Brazilian adolescents.
Methods: Cross-sectional study using data from the 2019 Brazilian National Health Survey. The simultaneity of factors of the consumption of ultra-processed foods, level of physical activity, smoking and alcohol use was analyzed, according to individual and contextual characteristics, estimating the odds ratios (OR) and respective 95% confidence intervals (95%CI) for fixed effects and variance and 95%CI for random effects, through multilevel polytomous logistic regression.

Objective: To verify the effect of physical exercise on the quality of life of patients with liver cirrhosis (LC).
Methods: the sample included controlled and randomized experimental studies of individuals with LC, at any stage of the disease, over 18 years of age, of both sexes, who performed any type of physical exercise compared to any other intervention or no intervention, with quality of life as the outcome assessed by the Chronic Liver Disease Questionnaire (CLDQ). The search for articles was conducted in 11 databases.

Background: Hypertensive disorders of pregnancy may be associated with an increased risk of adverse neurodevelopmental outcomes for the child, though no recent comprehensive meta-analyses exist. The aim of this study was to conduct a systematic review and meta-analysis examining the association between hypertensive disorders of pregnancy and child neurodevelopmental disabilities, intelligence, and educational outcomes.
Methods And Findings: A search was conducted of MEDLINE, CINAHL, Web of Science, and PsycINFO databases from inception until 18 September 2024.

Background: Poor olfaction may be associated with incident heart failure (HF) in older adults, but empirical evidence is scant.
Methods: We included 5,217 participants free of clinical HF and with a smell assessment in 2011-2013 from the Atherosclerosis Risk in Communities Study. Olfaction was measured by the 12-item Sniffin' Sticks odor identification test and defined as good (score 11-12), moderate (9-10), or poor (≤8).

While there has been extensive research on techniques for explainable artificial intelligence (XAI) to enhance AI recommendations, the metacognitive processes in interacting with AI explanations remain underexplored. This study examines how AI explanations impact human decision-making by leveraging cognitive mechanisms that evaluate the accuracy of AI recommendations. We conducted a large-scale experiment (N = 4,302) on Amazon Mechanical Turk (AMT), where participants classified radiology reports as normal or abnormal.
