Background: The pathogenesis of non-alcoholic fatty liver disease (NAFLD) with a global prevalence of 30% is multifactorial and the involvement of gut bacteria has been recently proposed. However, finding robust bacterial signatures of NAFLD has been a great challenge, mainly due to its co-occurrence with other metabolic diseases.

Results: Here, we collected public metagenomic data and integrated the taxonomy profiles with in silico generated community metabolic outputs, and detailed clinical data, of 1206 Chinese subjects w/wo metabolic diseases, including NAFLD (obese and lean), obesity, T2D, hypertension, and atherosclerosis.

Background: Blinding is essential for mitigating biases in trials of low back pain (LBP). Our main objectives were to assess the feasibility of blinding: (1) participants randomly allocated to active or placebo spinal manual therapy (SMT), and (2) outcome assessors. We also explored blinding by levels of SMT lifetime experience and recent LBP, and factors contributing to beliefs about the assigned intervention.

The Warburg effect, which describes the fermentation of glucose to lactate even in the presence of oxygen, is ubiquitous in proliferative mammalian cells, including cancer cells, but poses challenges for biopharmaceutical production as lactate accumulation inhibits cell growth and protein production. Previous efforts to eliminate lactate production in cells for bioprocessing have failed as lactate dehydrogenase is essential for cell growth. Here, we effectively eliminate lactate production in Chinese hamster ovary and in the human embryonic kidney cell line HEK293 by simultaneous knockout of lactate dehydrogenases and pyruvate dehydrogenase kinases, thereby removing a negative feedback loop that typically inhibits pyruvate conversion to acetyl-CoA.

Multi-omic quantitative trait loci link tandem repeat size variation to gene regulation in human brain.

Nat Genet

January 2025

Division of Computational Biomedicine, Department of Biological Chemistry, University of California, Irvine, Irvine, CA, USA.

Tandem repeat (TR) size variation is implicated in ~50 neurological disorders, yet its impact on gene regulation in the human brain remains largely unknown. In the present study, we quantified the impact of TR size variation on brain gene regulation across distinct molecular phenotypes, based on 4,412 multi-omics samples from 1,597 donors, including 1,586 newly sequenced ones. We identified ~2.

Soil erosion susceptibility maps and raster dataset for the hydrological basins of North Africa.

Sci Data

January 2025

University of Southern California, Viterbi School of Engineering, 3737 Watt Way, Powell Hall of Engineering, Los Angeles, CA, 90089, USA.

Soil erosion in North Africa modulates agricultural and urban developments as well as the impacts of flash floods. Existing investigations and associated datasets are mainly performed in localized urban areas, often representing a limited part of a watershed. The above compromises the implementation of mitigation measures for this vast area under accentuating extremes and continuous hydroclimatic fluctuations.

Childhood obesity poses a significant public health challenge, yet the molecular intricacies underlying its pathobiology remain elusive. Leveraging extensive multi-omics profiling (methylome, miRNome, transcriptome, proteins and metabolites) and a rich phenotypic characterization across two parts of Europe within the population-based Human Early Life Exposome project, we unravel the molecular landscape of childhood obesity and associated metabolic dysfunction. Our integrative analysis uncovers three clusters of children defined by specific multi-omics profiles, one of which characterized not only by higher adiposity but also by a high degree of metabolic complications.

Glioma is a highly fatal and heterogeneous brain tumor with few known risk factors. Our study examines genetically predicted variability in blood cell indices in relation to glioma risk and survival in 3418 cases and 8156 controls. We find that increased platelet to lymphocyte ratio (PLR) confers an increased risk of glioma (odds ratio (OR) = 1.

Language-discordant healthcare encounters-when the patient/caregiver and clinician are not able to communicate directly in the patient's/caregiver's preferred language-are associated with worse quality of care, increased adverse events, and research exclusion. Here, we describe the current state of language justice in clinical practice and research in the United States, Canada, and Spain, discuss the role of social determinants of health and language, in patient safety and health outcomes and review an example of culturally and linguistically concordant interventions to increase research participation. We close with practical and global strategies to increase multilingual research participation and to provide equitable patient- and family-centered care in pediatric hematology-oncology.

Background And Purpose: Prolonged venous transit (PVT), derived from computed tomography perfusion (CTP) time-to-maximum (T) maps, reflects compromised venous outflow (VO) in acute ischemic stroke due to large vessel occlusion (AIS-LVO). Poor VO is associated with worse clinical outcomes, but pre-treatment markers predictive of PVT are not well described.

Methods: We conducted a retrospective analysis of 189 patients with anterior circulation AIS-LVO who underwent baseline CT evaluation, including non-contrast CT, CT angiography, and CTP.

Conditional Generative Models for Synthetic Tabular Data: Applications for Precision Medicine and Diverse Representations.

Annu Rev Biomed Data Sci

January 2025

2Departments of Bioengineering and Genetics, Stanford University, Stanford, California, USA.

Tabular medical datasets, like electronic health records (EHRs), biobanks, and structured clinical trial data, are rich sources of information with the potential to advance precision medicine and optimize patient care. However, real-world medical datasets have limited patient diversity and cannot simulate hypothetical outcomes, both of which are necessary for equitable and effective medical research. Fueled by recent advancements in machine learning, generative models offer a promising solution to these data limitations by generating enhanced synthetic data.

Background: Research suggest that mind-body movement programs have beneficial effects on cognitive outcomes for older adults with cognitive decline. However, few studies have directly compared specific approaches to mind-body movement or studied the impact of remote program delivery.

Methods: In a 3-arm randomized controlled trial (RCT) for older adults with cognitive impairment, we are comparing a multidomain mind-body program that emphasizes movement, body awareness, personal meaningfulness, and social connection, and a traditional Chinese mind-body exercise (Tai Chi) to a health and wellness education control condition.

Electronic address:

Background: Fecal immunochemical testing (FIT) is a widely used first step for colorectal cancer (CRC) screening. Abnormal FIT results require a colonoscopy for screening completion and CRC diagnosis, but the rate of timely colonoscopy is low, especially among patients in safety-net settings. Multi-level factors at the clinic- and patient-levels influence colonoscopy completion after an abnormal FIT.

Persistent racial disparities in low birth weight (LBW) in the United States may be better understood through the adoption of a life course perspective that considers differential exposure and vulnerability of Black and White women to socioeconomic position across generations. Using a multigenerational dataset of singleton birth certificates from South Carolina from 1989 to 2020 linked along the maternal line, we constructed intergenerational social mobility trajectories of grandmaternal and maternal education and compared unadjusted and adjusted associations between trajectories and LBW among Black and White women. We found that White women were more likely to be upwardly mobile, and Black women to be downwardly mobile.
