Glycated Hemoglobin, Fasting Insulin and the Metabolic Syndrome in Males. Cross-Sectional Analyses of the Aragon Workers' Health Study Baseline
Background and Aims
Glycated hemoglobin (HbA1c) is currently used to diagnose diabetes
mellitus, while insulin has been relegated to research. Both, however,
may help understanding the metabolic syndrome and profiling patients. We
examined the association of HbA1c and fasting insulin with clustering of
metabolic syndrome criteria and insulin resistance as two essential
characteristics of the metabolic syndrome.
Methods
We used baseline data from 3200 non-diabetic male participants in the
Aragon Workers' Health Study. We conducted analysis to estimate
age-adjusted odds ratios (ORs) across tertiles of HbA1c and insulin.
Fasting glucose and Homeostatic model assessment - Insulin Resistance
were used as reference. Here we report the uppermost-to-lowest tertile
ORs (95\% CI).
Results
Mean age (SD) was 48.5 (8.8) years and 23\% of participants had
metabolic syndrome. The ORs for metabolic syndrome criteria tended to be
higher across HbA1c than across glucose, except for high blood pressure.
Insulin was associated with the criteria more strongly than HbA1c and
similarly to Homeostatic model assessment - Insulin Resistance
(HOMA-IR). For metabolic syndrome, the OR of HbA1c was 2.68, of insulin,
11.36, of glucose, 7.03, and of HOMA-IR, 14.40. For the clustering of 2
or more non-glycemic criteria, the OR of HbA1c was 2.10, of insulin,
8.94, of glucose, 1.73, and of HOMA-IR, 7.83. All ORs were statistically
significant. The areas under the receiver operating characteristics
curves for metabolic syndrome were 0.670 (across HbA1c values) and 0.770
(across insulin values), and, for insulin resistance, 0.647 (HbA1c) and
0.995 (insulin). Among non-metabolic syndrome patients, a small insulin
elevation identified risk factor clustering.
Conclusions
HbA1c and specially insulin levels were associated with metabolic
syndrome criteria, their clustering, and insulin resistance. Insulin
could provide early information in subjects prone to develop metabolic
syndrome.M. Laclaustra was supported in part by grant FIS CP08/00112 from

La casa individual y agrupada : miradas del abordaje y trayecto de la experiencia didáctica sobre el tema de proyecto
Ponencia presentada en las VI Jornadas de Investigación "Encuentro y Reflexión". Investigación, Enseñanza y Transferencia: Patrimonio Intelectual. Córdoba, Argentina. 2016La Cultura del Proyecto Arquitectónico contiene didácticas. El Proyecto es didáctico y también para autodidactas. La Casa, como primer espacio del continuum de la dimensión espacial de la vida humana, contiene hilos conductores que, a través de su historicidad, sostienen los genes de su necesidad y de su manifestación. Individual o agrupada, juega entre la tradición y la innovación, en un campo donde, desde la Enseñanza, es preciso transferir modos de abordaje pluriversales y multifacéticos, que pongan sobre la mesa sus variaciones, y los puntos de inflexión, desde donde re- nacen surgimientos tipológicos y espaciales alternativos. Rompiendo con lo habitual, que congela la energía del Proyecto, la investigación recoge, sistematiza y ensaya frentes de arranque posibles que, a través de un recorrido hermenéutico, partan desde la toma de sentido, para disponer y transitar experiencias herramentales y decisorias que, no sólo permitan trabajar con conceptos, sino, además, acotar el concepto del trabajo heurístico por descubrimiento y síntesis.http://hdl.handle.net/11086/5753Fil: Gutiérrez Crespo, Nora.

Single-reaction multi-antigen serological test for comprehensive evaluation of SARS-CoV-2 patients by flow cytometry
Here, we describe a new, simple, highly multiplexed serological test that generates a more complete picture of seroconversion than single antigen-based assays. Flow cytometry is used to detect multiple Ig isotypes binding to four SARS-CoV-2 antigens: the Spike glycoprotein, its RBD fragment (the main target for neutralizing antibodies), the nucleocapsid protein, and the main cysteine-like protease in a single reaction. Until now, most diagnostic serological tests measured antibodies to only one antigen and in some laboratory-confirmed patients no SARS-CoV-2-specific antibodies could be detected. Our data reveal that while most patients respond against all the viral antigens tested, others show a marked bias to make antibodies against either proteins exposed on the viral particle or those released after cellular infection. With this assay, it was possible to discriminate between patients and healthy controls with 100% confidence. Analysing the response of multiple Ig isotypes to the four antigens in combination may also help to establish a correlation with the severity degree of disease. A more detailed description of the immune responses of different patients to SARS-CoV-2 virus might provide insight into the wide array of clinical presentations of COVID-19.This work was supported by: Spanish National Research Council (CSIC-202020E079, CSIC-COVID19-028); Madrid Regional Government “IMMUNOTHERCAN” [S2017/BMD-3733-2 (MVG)]; Spanish Ministry of Science and Innovation [(MCIU/AEI/FEDER, EU, RTI2018-093569-B-I00 (MVG), SAF2017-82940-R (JMRF), SAF2017-83265-R (HTR); SAF2017-82886-R (FSM)]; Health Institute Carlos III (ISCIII) [RETICS Program RD16/0012/0006; RIER (EMGC); PI19/00549 (AA)]; “La Caixa Bank Foundation” (HR17-00016), Fondo Supera COVID (CRUE-Banco de Santander), both to FSM.Peer reviewe
Bead-assisted SARS-CoV-2 multi-antigen serological test allows effective identification of patients
Many new aspects of COVID-19 disease, including different clinical manifestations, have been identified during the pandemic. The wide array of symptoms and variation in disease severity after SARS-CoV-2 infection might be related to heterogeneity in the immune responses of different patients. Here we describe a new method for a simple multi-antigen serological test that generates a full picture of seroconversion in a single reaction. The assay is based on the detection by flow cytometry of multiple immunoglobulin classes (isotypes) specific for four SARS-CoV-2 antigens: the Spike glycoprotein (one of the highly immunogenic proteins), its RBD fragment (the major target for neutralising antibodies), the nucleocapsid protein and the main cysteine-like protease. Until now, most diagnostic serological tests measured antibodies to only one antigen and some patients seemed to not make any antibody response. Our data reveal that while most patients respond against all the viral antigens tested, others show a marked bias to make antibodies against either proteins exposed on the viral particle or those released after cellular infection. Combining all the four antigens and using machine learning techniques, it was possible to clearly discriminate between patients and healthy controls with 100% confidence. Further, combination of antigens and different immunoglobulin isotypes in this multi-antigen assay improved the classification of patients with mild and severe disease. Introduction of this method will facilitate massive screenings of patients to evaluate their immune response. It could also support vaccination campaigns both to select non-immune individuals and to distinguish infected patients from vaccine responders.This work was supported by the Spanish National Research Council (CSIC, project numbers

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2
The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
