    Background. COVID-19 is an ongoing global pandemic. Since the detection of the first cases of coronavirus disease 2019 (COVID-19) in Wuhan, China, the current pandemic has affected more than 25.3 million people worldwide. The aim of this study was to evaluate the relationship between coagulation abnormalities and prognosis in a cohort of patients with COVID-19. Methods. We performed a retrospective cohort study of 3581 patients admitted to Hospital La Paz (Madrid, Spain) due to respiratory infection by severe acute respiratory syndrome coronavirus from the beginning of the current pandemic to 15 July 2020. Results. Of the 3581 study patients, 48.94% were men, and 19.80% were healthcare workers. The median age was 62 years. Compared with the survivors, the non-survivors had lower prothrombin activity (82.5 (Interquartile range-IQR, 67-95) vs. 95.25 (IQR, 87-104) for non-survivors and survivors, respectively; p < 0.001), higher fibrinogen levels (748.5-IQR, 557-960) vs. 572.75 (IQR, 417-758; p < 0.001), and notably higher D-dimer levels (2329-IQR, 1086.12-5670.40) vs. 635.5 (IQR, 325.5-1194.8); p < 0.001). Conclusions. The evaluation of coagulation parameters could be an efficient measure for predicting the prognosis and improving the clinical management of patients with COVID-19

    In a previous study we reported that 25% of college students had a family history of type 2 diabetes (T2D), and 39% of hypertension. Interestingly, between 17 to 47% reported not knowing about T2D or hypertension, neither the existing obesity-metabolic problems (ESFUERSO study). The COVID-19 pandemic forced confinement and modifications in food intake, physical activity, and psychological stress. This study aimed to analyze if the immune Ig-G anti-RBD (protective epitope in S protein) response associated with type of vaccination, metabolic risk, perceived stress, and history of COVID-19 contacts. We included 116 students at the 3th year of follow up in the ESFUERSO cohort at Reynosa. Mean age 21.4 (SD 1.04) years old, BMI 28 (6.6), females 70% (81/116). The serum concentration of Ig-G anti-RGB measured by ELISA adjusted by sex, age, body fat percentage, and BMI was analyzed. Researchers performed a multiple regression analysis with Stata V17.0. We found that 70% of the students had a family history of diabetes, hypertension, and/or obesity at baseline. Only 5 (4%) students did not have any vaccine at the time of the study, 102 (88%) were vaccinated with Moderna or Pfizer and 9 (8%) with other vaccines (Cansino, Sinovac). The prevalence of positive anti-RBD was 91%. The body fat percentage interacted with sex (p=0.034) explaining the serum concentration of anti-RBD decreased as adiposity increases in men, but increased in women. The interaction remained is spite of type of vaccination. We found no differences among metabolic risks for food consumption, distress, uncertainty, lack of sleep, sadness, and anxiety were associated with metabolic problems. Our model predicts neutralizing anti-RBD had multiplicative interaction by sex and body fat percentage (increases in females and decreases in males), with no effects on stress score or food consumption

    Fe-clay catalysts have been prepared and tested for Orange II oxidation with H2O2 in aqueous solution. Thereaction is carried out in a batch reactor, using different hydrogen peroxide concentrations, and in a wide range oftemperature and pH values. Twelve samples were prepared, with three different iron loads (7.5, 13.0 and 17.0 %,w/w), and using four iron salts as precursors, namely Fe(II) acetate, Fe(II) oxalate, Fe(II) acetylacetonate and Fe(III)acetylacetonate. The samples were characterized using X-ray diffraction, thermal analysis, infrared spectroscopy andadsorption of nitrogen at 77K. The catalytic results show that these solids present good catalytic properties for thedegradation and mineralization of Orange II solutions, allowing to reach, in the best conditions and after 4h ofoxidation, 99% of dye degradation with 91% of TOC (Total Organic Carbon) reduction (at 70ÂșC), using only ca. 90 mgof clay catalyst per litre of solution. Nevertheless, 96% of dye removal with 82% of mineralization were also reachedat 30ÂșC. Besides, the amount of iron released into the final solution is lower than 1 ppm, in the worst of the cases,and 0.09 ppm in the best case

    Inverse Association between Dietary Iron Intake and Gastric Cancer: A Pooled Analysis of Case‐Control Studies of the Stop Consortium

    Background: Inconsistent findings have been reported regarding the relationship between dietary iron intake and the risk of gastric cancer (GC). Methods: We pooled data from 11 case‐control studies from the Stomach Cancer Pooling (StoP) Project. Total dietary iron intake was derived from food frequency questionnaires combined with national nutritional tables. We derived the odds ratios (ORs) and 95% confidence intervals (CIs) for quartiles of dietary iron through multivariable unconditional logistic regression models. Secondary analyses stratified by sex, smoking status, caloric intake, anatomical subsite and histological type were performed. Results: Among 4658 cases and 12247 controls, dietary iron intake was inversely associated with GC (per quartile OR 0.88; 95% CI: 0.83–0.93). Results were similar between cardia (OR = 0.85, 95% CI = 0.77–0.94) and non‐cardia GC (OR = 0.87, 95% CI = 0.81–0.94), and for diffuse (OR = 0.79, 95% CI = 0.69–0.89) and intestinal type (OR = 0.88, 95% CI = 0.79–0.98). Iron intake exerted an independent effect from that of smoking and salt intake. Additional adjustment by meat and fruit/vegetable intake did not alter the results. Conclusions: Dietary iron is inversely related to GC, with no difference by subsite or histological type. While the results should be interpreted with caution, they provide evidence against a direct effect of iron in gastric carcinogenesis

    Two-particle angular correlations between unidentified charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV. The transverse-momentum range 0.7 <pT,assoc<pT,trig< < p_{\rm{T}, assoc} < p_{\rm{T}, trig} < 5.0 GeV/cc is examined, to include correlations induced by jets originating from low momen\-tum-transfer scatterings (minijets). The correlations expressed as associated yield per trigger particle are obtained in the pseudorapidity range ∣η∣<0.9|\eta|<0.9. The near-side long-range pseudorapidity correlations observed in high-multiplicity p-Pb collisions are subtracted from both near-side short-range and away-side correlations in order to remove the non-jet-like components. The yields in the jet-like peaks are found to be invariant with event multiplicity with the exception of events with low multiplicity. This invariance is consistent with the particles being produced via the incoherent fragmentation of multiple parton--parton scatterings, while the yield related to the previously observed ridge structures is not jet-related. The number of uncorrelated sources of particle production is found to increase linearly with multiplicity, suggesting no saturation of the number of multi-parton interactions even in the highest multiplicity p-Pb collisions. Further, the number scales in the intermediate multiplicity region with the number of binary nucleon-nucleon collisions estimated with a Glauber Monte-Carlo simulation.Comment: 23 pages, 6 captioned figures, 1 table, authors from page 17, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/161

    Multi-particle azimuthal correlations in p-Pb and Pb-Pb collisions at the CERN Large Hadron Collider

    Full text link
    Measurements of multi-particle azimuthal correlations (cumulants) for charged particles in p-Pb and Pb-Pb collisions are presented. They help address the question of whether there is evidence for global, flow-like, azimuthal correlations in the p-Pb system. Comparisons are made to measurements from the larger Pb-Pb system, where such evidence is established. In particular, the second harmonic two-particle cumulants are found to decrease with multiplicity, characteristic of a dominance of few-particle correlations in p-Pb collisions. However, when a âˆŁÎ”Î·âˆŁ|\Delta \eta| gap is placed to suppress such correlations, the two-particle cumulants begin to rise at high-multiplicity, indicating the presence of global azimuthal correlations. The Pb-Pb values are higher than the p-Pb values at similar multiplicities. In both systems, the second harmonic four-particle cumulants exhibit a transition from positive to negative values when the multiplicity increases. The negative values allow for a measurement of v2{4}v_{2}\{4\} to be made, which is found to be higher in Pb-Pb collisions at similar multiplicities. The second harmonic six-particle cumulants are also found to be higher in Pb-Pb collisions. In Pb-Pb collisions, we generally find v2{4}≃v2{6}≠0v_{2}\{4\} \simeq v_{2}\{6\}\neq 0 which is indicative of a Bessel-Gaussian function for the v2v_{2} distribution. For very high-multiplicity Pb-Pb collisions, we observe that the four- and six-particle cumulants become consistent with 0. Finally, third harmonic two-particle cumulants in p-Pb and Pb-Pb are measured. These are found to be similar for overlapping multiplicities, when a âˆŁÎ”Î·âˆŁ>1.4|\Delta\eta| > 1.4 gap is placed.Comment: 25 pages, 11 captioned figures, 3 tables, authors from page 20, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/87

    Salt intake and gastric cancer: a pooled analysis within the Stomach cancer Pooling (StoP) Project

    Get PDF
    Purpose: Previous studies show that consuming foods preserved by salting increases the risk of gastric cancer, while results on the association between total salt or added salt and gastric cancer are less consistent and vary with the exposure considered. This study aimed to quantify the association between dietary salt exposure and gastric cancer, using an individual participant data meta-analysis of studies participating in the Stomach cancer Pooling (StoP) Project. Methods: Data from 25 studies (10,283 cases and 24,643 controls) from the StoP Project with information on salt taste preference (tasteless, normal, salty), use of table salt (never, sometimes, always), total sodium intake (tertiles of grams/day), and high-salt and salt-preserved foods intake (tertiles of grams/day) were used. A two-stage approach based on random-effects models was used to pool study-specific adjusted (sex, age, and gastric cancer risk factors) odds ratios (aORs), and the corresponding 95% confidence intervals (95% CI). Results: Gastric cancer risk was higher for salty taste preference (aOR 1.59, 95% CI 1.25–2.03), always using table salt (aOR 1.33, 95% CI 1.16–1.54), and for the highest tertile of high-salt and salt-preserved foods intake (aOR 1.24, 95% CI 1.01–1.51) vs. the lowest tertile. No significant association was observed for the highest vs. the lowest tertile of total sodium intake (aOR 1.08, 95% CI 0.82–1.43). The results obtained were consistent across anatomic sites, strata of Helicobacter pylori infection, and sociodemographic, lifestyle and study characteristics. Conclusion: Salty taste preference, always using table salt, and a greater high-salt and salt-preserved foods intake increased the risk of gastric cancer, though the association was less robust with total sodium intake. © 2022, The Author(s), under exclusive licence to Springer Nature Switzerland AG.This study was funded by national funds from the Foundation for Science and Technology—FCT (Portuguese Ministry of Science, Technology and Higher Education), under the Unidade de Investigação em Epidemiologia—Instituto de SaĂșde PĂșblica da Universidade do Porto (EPIUnit; UIDB/04750/2020), by the Associazione Italiana per la Ricerca sul Cancro (AIRC), Project no. 21378 (Investigator Grant), and the Agency for Management of University and Research Grants (AGAUR) of the Catalan Government (Grant 2017SGR723).

    Para los estudiosos y el pĂșblico interesado en los asuntos municipales, 2013 fue un año emblemĂĄtico porque se cumplieron tres dĂ©cadas de la reforma al artĂ­culo 115 constitucional, precepto que sustancia la vida institucional de los municipios mexicanos. La vida municipal, merced a este periodo, se ha revitalizado, aunque de manera diferenciada entre caso y caso, pues la heterogeneidad econĂłmica, polĂ­tica y social persiste, asĂ­ como sus efectos adversos, sobre los municipios mĂĄs rezagados; ello es recordatorio de las deudas pendientes del Estado con esta expresiĂłn local. Tal revitalizaciĂłn ha alcanzado a la discusiĂłn acadĂ©mica con un resultado exuberante en producciĂłn editorial que da cuenta de significativos cambios en la vida asociada
