Obesity predisposes to type 2 diabetes so often that the combination is called diabesity. The aim of this study was to determine the prevalence of diabesity in the working population and to analyze the variables associated with it.
Cross-sectional study between January 2019 and June 2020 by 418,343 workers from 18 to 67 year-old, from different professions and Spanish geographic areas. The prevalence of diabesity was determined with six different for-mulae for obesity BMI (body mass index), CUN BAE (Clínica Universidad de Navarra Body Adiposity Estimator), ECORE-BF (Equation Córdoba for Estimation of Body Fat), Formula Palafolls, FMI (fat mass index) of Deuremberg and RFM (relative fat mass). The association between diabetes and age, sex, social class and tobacco was analyzed.
The global prevalence of diabetes ranged from 2.6% for BMI to 5.8% for the Palafolls formula. The variable most related to diabesity was age over 50 years (OR=5.9; 95%CI 5.7-6.2 for BMI, and OR=8.1; 95%CI 7.9-8.4 for FMI of Deuremberg). Male sex and social class III related with diabesity estimated by all formulas, while being a smoker was only related with the Palafolls formula.
Diabesity prevalence varies depending on the formula used, with much lower prevalence among women and increased with age independent of the formula used. Its prevalence is higher in the lower social classes.

To make eye tracking freely and widely available for MRI research, we developed DeepMReye, a convolutional neural network (CNN) that decodes gaze position from the magnetic resonance signal of the eyeballs. It performs cameraless eye tracking at subimaging temporal resolution in held-out participants with little training data and across a broad range of scanning protocols. selleckchem Critically, it works even in existing datasets and when the eyes are closed. Decoded eye movements explain network-wide brain activity also in regions not associated with oculomotor function. This work emphasizes the importance of eye tracking for the interpretation of fMRI results and provides an open source software solution that is widely applicable in research and clinical settings.
Systemic levels of pro-inflammatory cytokines and activated complement components affect the risk and/or progression of neovascular age-related macular degeneration (AMD). This study investigated the effect of serum pro-inflammatory cytokine levels and complement pathway activity on the clinical response to vascular endothelial growth factor (VEGF) inhibition in neovascular AMD.
Sixty-five patients with a new diagnosis of neovascular AMD were observed over a six-month period in a single-centre, longitudinal cohort study. At each visit, the visual acuity score (VAS), central macular thickness (CMT), serum levels of CRP, pro-inflammatory cytokines (TNF-α, IL-1β, IL-2, IL-6 and IL-8), and complement pathway activity were measured. Participant DNA samples were sequenced for six complement pathway single nucleotide polymorphisms (SNPs) associated with AMD.
A statistically significant difference in VAS was observed for serum levels of TNF-α only there was a gain in VAS (from baseline) of 1.37 for participants below the 1st quartile of mean concentration compared to a reduction of 2.71 for those above the 3rd quartile. Statistical significance was maintained after Bonferroni correction (P value set at <0.006). link2 No significant differences in CMT were observed. In addition, statistically significant differences, maintained after Bonferroni correction, were observed in serum complement activity for participants with the following SNPs CFH region (rs1061170), SERPING1 (rs2511989) and CFB (rs641153). Serum complement pathway components did not significantly affect VAS.
Lower serum TNF-α levels were associated with an increase in visual acuity after anti-VEGF therapy. This suggests that targeting pro-inflammatory cytokines may augment treatment for neovascular AMD.

Accurate pre-operative diagnosis of orbital lesions supports appropriate prioritisation of patients into available theatre time. We examine the accuracy of pre-operative clinico-radiological diagnosis in a tertiary centre with weekly dedicated orbital clinics and associated multi-disciplinary team meetings.
A retrospective case notes review was undertaken for all patients who had an orbital biopsy performed at Bristol Eye Hospital between 2007 and 2017. In this centre, pre-operative clinico-radiological differential diagnoses are discussed during multi-disciplinary team meetings including two orbital specialist ophthalmologists and a specialist neuro-radiologist. Clinico-radiological diagnoses were compared with histopathological outcomes. Subcategory analysis according to histopathological diagnosis was undertaken to look for trends.
172 biopsies were taken from 156 patients, median age 59 years (range 3 months to 91 years). 60.9% of patient were females, with equal numbers of right and left-sided bioprted by Koukoulli et al. Specialist head and neck radiology input via regular orbital multi-disciplinary meetings might be reciprocally educational and explain this difference. The authors recommend all surgeons who perform orbital surgery should have access to such multi-disciplinary meetings.Alzheimer disease (AD) is the most prevalent type of dementia. It is marked by severe memory loss and cognitive decline, and currently has limited effective treatment options. Although individuals with AD have common neuropathological hallmarks, emerging data suggest that the disease has a complex polygenic aetiology, and more than 25 genetic loci have been linked to an elevated risk of AD and dementia. Nevertheless, our ability to decipher the cellular and molecular mechanisms that underlie genetic susceptibility to AD, and its progression and severity, remains limited. Here, we discuss ongoing efforts to leverage genomic data from patients using cellular reprogramming technologies to recapitulate complex brain systems and build in vitro discovery platforms. Much attention has already been given to methodologies to derive major brain cell types from pluripotent stem cells. We therefore focus on technologies that combine multiple cell types to recreate anatomical and physiological properties of human brain tissue in vitro. We discuss the advances in the field for modelling four domains that have come into view as key contributors to the pathogenesis of AD the blood-brain barrier, myelination, neuroinflammation and neuronal circuits. We also highlight opportunities for the field to further interrogate the complex genetic and environmental factors of AD using in vitro models.Predicting the behaviour of others is an essential part of social cognition. Despite its ubiquity, social prediction poses a poorly understood generalization problem we cannot assume that others will repeat past behaviour in new settings or that their future actions are entirely unrelated to the past. We demonstrate that humans solve this challenge using a structure learning mechanism that uncovers other people’s latent, unobservable motives, such as greed and risk aversion. In four studies, participants (N = 501) predicted other players‘ decisions across four economic games, each with different social tensions (for example, Prisoner’s Dilemma and Stag Hunt). Participants achieved accurate social prediction by learning the stable motivational structure underlying a player’s changing actions across games. This motive-based abstraction enabled participants to attend to information diagnostic of the player’s next move and disregard irrelevant contextual cues. Participants who successfully learned another’s motives were more strategic in a subsequent competitive interaction with that player in entirely new contexts, reflecting that social structure learning supports adaptive social behaviour.The development of a functional vasculature requires the coordinated control of cell fate, lineage differentiation and network growth. Cellular proliferation is spatiotemporally regulated in developing vessels, but how this is orchestrated in different lineages is unknown. Here, using a zebrafish genetic screen for lymphatic-deficient mutants, we uncover a mutant for the RNA helicase Ddx21. Ddx21 cell-autonomously regulates lymphatic vessel development. An established regulator of ribosomal RNA synthesis and ribosome biogenesis, Ddx21 is enriched in sprouting venous endothelial cells in response to Vegfc-Flt4 signalling. Ddx21 function is essential for Vegfc-Flt4-driven endothelial cell proliferation. In the absence of Ddx21, endothelial cells show reduced ribosome biogenesis, p53 and p21 upregulation and cell cycle arrest that blocks lymphangiogenesis. Thus, Ddx21 coordinates the lymphatic endothelial cell response to Vegfc-Flt4 signalling by balancing ribosome biogenesis and p53 function. This mechanism may be targetable in diseases of excessive lymphangiogenesis such as cancer metastasis or lymphatic malformation.The Human Reference Atlas (HRA) aims to map all of the cells of the human body to advance biomedical research and clinical practice. This Perspective presents collaborative work by members of 16 international consortia on two essential and interlinked parts of the HRA (1) three-dimensional representations of anatomy that are linked to (2) tables that name and interlink major anatomical structures, cell types, plus biomarkers (ASCT+B). We discuss four examples that demonstrate the practical utility of the HRA.Homologous recombination repairs DNA double-strand breaks (DSB) using an intact dsDNA molecule as a template. It entails a homology search step, carried out along a conserved RecA/Rad51-ssDNA filament assembled on each DSB end. Whether, how and to what extent a DSB impacts chromatin folding, and how this (re)organization in turns influences the homology search process, remain ill-defined. Here we characterize two layers of spatial chromatin reorganization following DSB formation in Saccharomyces cerevisiae. Although cohesin folds chromosomes into cohesive arrays of ~20-kb-long chromatin loops as cells arrest in G2/M, the DSB-flanking regions interact locally in a resection- and 9-1-1 clamp-dependent manner, independently of cohesin, Mec1ATR, Rad52 and Rad51. This local structure blocks cohesin progression, constraining the DSB region at the base of a loop. Functionally, cohesin promotes DSB-dsDNA interactions and donor identification in cis, while inhibiting them in trans. link3 This study identifies multiple direct and indirect ways by which cohesin regulates homology search during recombinational DNA repair.Massive single-cell profiling efforts have accelerated our discovery of the cellular composition of the human body while at the same time raising the need to formalize this new knowledge. Here, we discuss current efforts to harmonize and integrate different sources of annotations of cell types and states into a reference cell ontology. We illustrate with examples how a unified ontology can consolidate and advance our understanding of cell types across scientific communities and biological domains.
