Introduction: C-reactive protein/albumin (CAR) and albumin/fibrinogen (AFR) ratios are novel biomarkers of inflammation that indicate activity status, severity, and response to treatment in systemic lupus erythematosus (SLE); however, the potential value of these ratios in differentiating SLE patients from healthy individuals has not been evaluated. Objective: To evaluate the value of CAR and AFR as potential biomarkers for differentiation of SLE. Material and methods: Analytical case-control study, performed in a SLE group (n=71) and a control group (n=50). Clinical, inflammatory and cardiometabolic parameters with possible diagnostic value (CAR and AFR) were quantified. The diagnostic threshold was estimated by receiver operating characteristic (ROC) curve, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for each ratio and 95% confidence intervals. Results: The diagnostic thresholds for AFR and CAR were 13.6 and 0.016, respectively. Sensitivity was 53.53% for AFR and 100% for CAR. The specificity was 98% for AFR and 100% for CAR. The ROC curve showed that CAR had a higher area under the curve (AUC) (AUC=1) compared to AFR (AUC=0.76) statistically significant (p<0.001), according to the AUC values, AFR was considered a favorable biomarker and CAR was considered an excellent biomarker to differentiate SLE. Conclusions: CAR is a biomarker with great potential, low cost and easy to measure, which could improve the sensitivity and specificity to diagnose SLE. [ABSTRACT FROM AUTHOR]

Antecedents and objectives:The coronavirus disease 2019 (COVID-19) has spread worldwide to be reported to date 3.446.072 cases in Spain which causes a very challenging situation for the Spanish Health Care System. This study aims to describe the adjustments, analytical and microbiological parameters of patients clinically diagnosed with SARSCoV-2 infection in the first weeks of the pandemic. Material and methods:A retrospective observational study. 180 patients have been included in the study since they were treated by our emergency unit for a period beginning on March 9 ending on April 24, 2020. They were clinically diagnosed with COVID-19. The study provides analysis on their demographic, analytical and microbiological data. Results: The average patient was 64 years old and 60.6 % were men. 86.1 % obtained a positive RT-PCR, 3.9 % a negative one. The 10 % left provided an inconclusive result. IgG antibodies were detected in 84.4 % and IgM antibodies in 85.6 %. 26.0 % of our patients suffered from lymphopenia and 13.6 % thrombocytopenia. 67.4 % and 77.3 % had respectively D-dimer and fibrinogen levels above the normal range. High serum levels of ALT (45.0 %), AST (30.5 %), LDH (71.9 %), C-reactive protein (74.5 %), and procalcitonin (11.9 %) were reported. High ferritin concentrations were found in 75.2 %. Conclusions: The alterations observed in the analytical parameters are the most common in cases of COVID-19. These high level rates have been considered prognostic markers of severity and mortality.

Building risk spaces differ according to the history of the urban development and the environmental context of each city. The aim of this work is to analyze historical-territorial periods that generated the construction of flood risk areas in the city of San Carlos de Bariloche, Río Negro, Argentina. The Dagwood Sandwich methodology was applied to analyze the urbanization and its transformations over time and the role played by the environment and the impacts caused by society. Correlations were observed within six historical-territorial crosscutting moments at different scales (local, provincial, national and international) and the development of exposed spaces to different dangers. This methodology allows identifying and acknowledging the current and historical environmental situation, in order to forecast possible trends of urban expansion and the generation of new flood-risk territories.

Introduction: The remineralizing property of saliva contributes to maintain the physical and chemical integrity of the mineral structure of teeth, which protects it from the installation and evolution of dental caries. Objective: To relate sialometry, buffering capacity (BC), calcium and phosphate in whole stimulated saliva, and calcium and phosphate in gingival crevicular fluid (GCF), with school children caries severity and activity. Materials and methods: 36 schoolchildren aged 6 years; 18 with caries (ICDAS>1 group) and 18 without caries (ICDAS=0 group) was selected. The severity and activity of dental caries was diagnosed in the primary dentition; in the occlusal surface (OS) of molars and in the vestibular (VS) of the anterior teeth, by ICDAS-II. Results: In OS it was evidenced more severity of caries than in VS. The concentration of calcium in saliva and phosphate in healthy teeth GCF were higher in the ICDAS>1 group. The concentration of calcium in GCF was higher in the ICDAS=0 group than in the decayed teeth of the ICDAS>1 group. Statistically significant association between the frequency of active caries with the concentration of phosphate in GCF of teeth with caries, and between the severity of caries with BF and the concentration of phosphate in the GCF of teeth with caries. Conclusion: It was evidenced an association between dental caries with BC and buccal calcium and phosphate. [ABSTRACT FROM AUTHOR]

A comparative study was made between permutation and classical tests, applied to double-ordinal R × C dimension contingency tables, using as a measure of comparison the difference between the exact p-value and its classical counterpart. Five examples were analyzed, four published in the international scientific literature and one proposed by the authors, in order to show under which conditions both approaches present a different or equivalent behavior for the Jonckeere-Terpstra and linear-linear association tests. The software StatXact 9.0 was used for the calculation of the pvalues asymptotic, exact, and obtained by the Monte Carlo test. The results showed that for the doubly ordinal contingency tables, the convergence between the exact and classical p-values was reached both for small sample sizes and for unbalanced tables. For this reason, it is very frequent that the tests present a similar behavior and the same decisions are taken in both methodologies. [ABSTRACT FROM AUTHOR]

Serological tests can identify infectious agents in biological samples. Their efficiency is evaluated through the discriminatory accuracy, which depends on a decision threshold. The standard methodology and the receiver operating characteristic curve (ROC) allow to obtain such threshold, and both methodologies are used indistinctly in practice. A comparative study of the discriminatory accuracy of both methods was performed. A set of values of antibodies to Leishmania in patients previously classified as sick or healthy was used, and computer simulations under homoscedastic and heteroscedastic conditions were made. On these data the standard methodology and the ROC curve were applied. The parameters sensitivity, specificity, %Sensitivity = 100%, %Specificity = 100% and %Perfect decision were calculated. Results showed that the discriminatory accuracy of the standard methodology favors specificity, while the ROC curve shows a balance between sensitivity and specificity, which increase as the average population of sick patients moves away from the average of the healthy population, in addition to present a greater proportion of perfect decision. The decision thresholds were affected by heteroscedasticity. The ROC curve showed better discriminatory precision and its use for calculating decision thresholds in serological testing is recommended. [ABSTRACT FROM AUTHOR]

This cross-sectional study evaluates the association between stress-related situations and social support with treatment adherence, in a sample of 173 hypertensive patients with overweight or obesity. Participants answered questions related to treatment adherence (consumption of prescription drugs, according to the doses and times specified). They were considered three stress-related situations (decision making, tolerance to ambiguity and tolerance to frustration) and two types of social support (emotional and confidence) as predictors of adherence. Multiple linear regression analysis showed the influence of two stress-related situations (decision making and tolerance for ambiguity) in overweight patients, and social support in patients with obesity. The association of stress-related situations and social support with the practice of three adherence behaviors was different depending on the patients was different depending on whether the patient is overweight or obese. We discuss the implications of findings for the purposes of designing, implementing and evaluating programs to improve treatment adherence in hypertensive patients. [ABSTRACT FROM AUTHOR]

A cross-sectional study was conducted with the aim to test if the perceived difficulty to deal with social relationships would affect the role of a set of psychological variables on the practice of the adherence behaviors to antiretroviral therapy in a group of 111 people with HIV. Participants responded at to two self-administered questionnaires: Psychological variables and adherence behaviors, and Stress-related situations. A multiple regression analysis showed that the effect of psychological variables depends on how difficulties to establish social relationships are valuated: If there are difficulties, the weight is shifted to the reasons underlying adherence behavior (F [1, 44]= 49.582, p <.001), if there are none, it moves to an interaction between motives and competences in the past (F [2, 62]= 22.280, p <.001). The results have profound implications for the design of intervention programs, in which the objectives should be targeted to facilitate and/or improve in adults with HIV: Social competence to interact efficiently with significant people in their immediate environment, the individual psychological adjustment, as well as the efficient practice of adherence behaviors.
