Abstract
Simple Summary There is an alarming increase of cardiovascular disease (CVD) and type 2 diabetes (T2D) in Mexican nationals and Mexican Americans. Studying adipose tissue (AT) dysfunction and early biomarkers of cardiovascular and immunometabolic risk in Mexican nationals may have a strong impact on future public health policies for US-born Mexican Americans and other populations of Mexican origin in the US. The goal of this study is to evaluate the early transition towards healthy/unhealthy adipose tissue expansion to identify AT dysfunction through systemic, molecular and OMICS measures in the fasting and fed states in symptom-free volunteers with no history of age-related chronic diseases in support of precision medicine and discovery. Abstract We previously reported preliminary characterization of adipose tissue (AT) dysfunction through the adiponectin/leptin ratio (ALR) and fasting/postprandial (F/P) gene expression in subcutaneous (SQ) adipose tissue (AT) biopsies obtained from participants in the GEMM study, a precision medicine research project. Here we present integrative data replication of previous findings from an increased number of GEMM symptom-free (SF) adults (N = 124) to improve characterization of early biomarkers for cardiovascular (CV)/immunometabolic risk in SF adults with AT dysfunction. We achieved this goal by taking advantage of the rich set of GEMM F/P 5 h time course data and three tissue samples collected at the same time and frequency on each adult participant (F/P blood, biopsies of SQAT and skeletal muscle (SKM)). We classified them with the presence/absence of AT dysfunction: low (<1) or high (>1) ALR. We also examined the presence of metabolically healthy (MH)/unhealthy (MUH) individuals through low-grade chronic subclinical inflammation (high sensitivity C-reactive protein (hsCRP)), whole body insulin sensitivity (Matsuda Index) and Metabolic Syndrome criteria in people with/without AT dysfunction. Molecular data directly measured from three tissues in a subset of participants allowed fine-scale multi-OMIC profiling of individual postprandial responses (RNA-seq in SKM and SQAT, miRNA from plasma exosomes and shotgun lipidomics in blood). Dynamic postprandial immunometabolic molecular endophenotypes were obtained to move towards a personalized, patient-defined medicine. This study offers an example of integrative translational research, which applies bench-to-bedside research to clinical medicine. Our F/P study design has the potential to characterize CV/immunometabolic early risk detection in support of precision medicine and discovery in SF individuals.

Abstract
Interactions between macrophages and adipocytes are early molecular factors influencing adipose tissue (AT) dysfunction, resulting in high leptin, low adiponectin circulating levels and low-grade metaflammation, leading to insulin resistance (IR) with increased cardiovascular risk. We report the characterization of AT dysfunction through measurements of the adiponectin/leptin ratio (ALR), the adipo-insulin resistance index (Adipo-IRi), fasting/postprandial (F/P) immunometabolic phenotyping and direct F/P differential gene expression in AT biopsies obtained from symptom-free adults from the GEMM family study. AT dysfunction was evaluated through associations of the ALR with F/P insulin-glucose axis, lipid-lipoprotein metabolism, and inflammatory markers. A relevant pattern of negative associations between decreased ALR and markers of systemic low-grade metaflammation, HOMA, and postprandial cardiovascular risk hyperinsulinemic, triglyceride and GLP-1 curves was found. We also analysed their plasma non-coding microRNAs and shotgun lipidomics profiles finding trends that may reflect a pattern of adipose tissue dysfunction in the fed and fasted state. Direct gene differential expression data showed initial patterns of AT molecular signatures of key immunometabolic genes involved in AT expansion, angiogenic remodelling and immune cell migration. These data reinforce the central, early role of AT dysfunction at the molecular and systemic level in the pathogenesis of IR and immunometabolic disorders.

Abstract
BACKGROUND Palliative care is an evolving but underdeveloped practice in Mexico. OBJECTIVE The primary end point of this prospective observational study was to identify internal medicine inpatients fulfilling advanced criteria within a second-level hospital. Secondary end points were symptom burden, treatment, resource utilization, and one-year survival. DESIGN AND MEASUREMENTS The 390-sample size calculation was based on previous studies where 15% of inpatients fulfilled palliative care needs. Consecutive admissions were assessed to identify patients with any of the following: cancer, cardiac, renal, hepatic insufficiency, COPD, AIDS, stroke, or fragility until sample size was completed. After obtaining informed consent, interview to patient, attending physician, and chart review was completed to identify any of the following advanced disease criteria in each patient: (1) Surprise question to attending physician of the possibility of the patient dying in the following year, (2) Palliative Performance Scale (PPS) <50, and (3) Advanced disease specific criteria. Interview also included presence of symptoms, functional capacity, and previous resource utilization. Treatment offered was analyzed only on day of admission. One-year follow-up to assess survival was done through the state death certificates. RESULTS Out of 390 patients, 131 (34%) had any of the diseases studied. Out of 131 patients, 86 (66%) had at least one of the three inclusion criteria for advanced disease. Out of 86 patients, 70 (81%) advanced disease patients died after one-year follow-up. Comparison between patients with no advanced disease (no criteria) versus advanced disease (at least one criteria) showed a significant difference in mean PPS, nutrition status, survival days, inhospital death, weight loss, dependency on activities of daily living, and previous multiple emergency room visits. Advanced disease patients with no death at one year follow-up had significantly more new admissions to that hospital. CONCLUSIONS The number of patients requiring palliative care in internal medicine wards may be excessive to the current palliative care structures available.

Abstract
Whole-transcriptome expression profiling provides novel phenotypes for analysis of complex traits. Gene expression measurements reflect quantitative variation in transcript-specific messenger RNA levels and represent phenotypes lying close to the action of genes. Understanding the genetic basis of gene expression will provide insight into the processes that connect genotype to clinically significant traits representing a central tenet of system biology. Synchronous in vivo expression profiles of lymphocytes, muscle, and subcutaneous fat were obtained from healthy Mexican men. Most genes were expressed at detectable levels in multiple tissues, and RNA levels were correlated between tissue types. A subset of transcripts with high reliability of expression across tissues (estimated by intraclass correlation coefficients) was enriched for cis-regulated genes, suggesting that proximal sequence variants may influence expression similarly in different cellular environments. This integrative global gene expression profiling approach is proving extremely useful for identifying genes and pathways that contribute to complex clinical traits. Clearly, the coincidence of clinical trait quantitative trait loci and expression quantitative trait loci can help in the prioritization of positional candidate genes. Such data will be crucial for the formal integration of positional and transcriptomic information characterized as genetical genomics.
