BACKGROUND We aimed to study the associations of adipocytokines, endothelial damage markers, and high-sensitivity C-reactive protein (hs-CRP) with metabolic syndrome (MetS) components. METHODS This cross-sectional study included 202 subjects categorized into MetS and No-MetS according to Harmonizing Adult Treatment Panel III. RESULTS Subjects with MetS showed higher levels of proinflammatory molecules but significantly lower adiponectin levels than subjects with No-MetS. Among the studied adipocytokines, plasminogen activator inhibitor-1 (PAI-1) and adiponectin showed the strongest associations with most MetS components. PAI-1 was associated with MetS (odds ratio (OR) 1.107 (1.065–1.151), P < 0.0001), whereas adiponectin was inversely associated with MetS (OR 0.710 (0.610–0.825), P < 0.0001). Following adjustment by sex, age, body mass index, and 24-hour urinary sodium excretion in a multivariate analysis, the association of PAI-1 (OR 1.090 (1.044–1.137), P < 0.0001) and adiponectin (OR 0.634 (0.519–0.775), P < 0.0001) with MetS remained significant. Multivariate analyses supported a model in which systolic blood pressure (BP) could be predicted by PAI-1, hs-CRP, and matrix metalloproteinase 2 (R 2 = 0.125; P = 0.04); diastolic BP (R 2 = 0.218; P = 0.0001) and glucose (R 2 = 0.074; P = 0.0001) could be predicted by PAI-1; waist circumference could be predicted by PAI-1 and hs-CRP (R 2 = 0.28; P = 0.016). Receiver operating characteristic curve analysis showed that a PAI-1 concentration had the best sensitivity and specificity for discriminating subjects with MetS. CONCLUSION PAI-1 and adiponectin rendered the most robust associations with MetS components in a general population, indicating that unfavorable adipose tissue performance is a key contributor to these metabolic anomalies. Further prospective analyses should allow establishing whether these adipocytokines can anticipate the progress of MetS and cardiovascular risk. [ABSTRACT FROM AUTHOR]

The objective of the study was to evaluate the effect of the bioproducts Ecomic® (Mycorrhizae), Azofert F® (Rhizobia) and QuitoMax® (chitosan) on tomato yield when applied to seeds prior to sowing. Treated seeds were sown in a traditional seedbed under a completely randomized design. Plants were planted at 0.90 m and 0.30 m apart. During the reproductive stage of the crop, the variables number of flowers and number of fruits were counted. At the third harvest, polar diameter, equatorial diameter, fruit mass and yield were evaluated. The bioproducts applied produced variations in the variables evaluated, obtaining the best results when the seeds were embedded with QuitoMax®, Azofert® and Ecomic®, with a yield of 35 t ha-¹, 30 t ha-¹, 28 t ha-¹, respectively, and 25 t ha-¹ in the control treatment.

The work was carried out in the municipality of Guisa, Granma province, in a traditional nursery. The sowing was carried out with tobacco seeds (Nicotiana tabacum L.) of the "Corojo 2006" variety, soaked for 8 hours in a QuitoMax® solution, in a concentration of 1 g L-1 and untreated seeds. The treatments evaluated were: 1) Treatment only to seeds, 2) Treatment to seeds and seedlings, 3) Treatment only to seedlings and 4) Control Treatment (without treating seeds or seedlings), on a randomized block design. At 10, 20 and 30 days after germination (DDG), 10 plants were taken per treatment and the variable: height of the plants was measured. At 45 days after germination, 10 plants were selected per treatment and the variables plant height, number of leaves, stem diameter, root length, fresh mass of plants. For statistical processing, a double classification analysis of variance was used, with the STATISTICA statistical package, and Tukey's multiple comparison test of the mean, for a significance level of 5%, when a difference was found between the means. The best behavior of the quality variables of the postures is obtained when applying the treatment to seeds and seedlings. [ABSTRACT FROM AUTHOR]

Respiratory syncytial virus (RSV) is the agent that causes more hospitalizations and deaths due to lower acute respiratory infection. Its distribution is widespread, and almost every child has been infected by the age of two years. Different risk populations have been identified: preterm newborns (NB), children with congenital heart disease, bronchopulmonary dysplasia, Down syndrome, cystic fibrosis, asthmatics, neuromuscular diseases, among others. However, preterm NBs, children with congenital heart disease or bronchopulmonary dysplasia show higher rates of hospitalization and death from RSV. In the late 90s, monoclonal antibodies against RSV were developed, with demonstrated efficacy and safety for the prevention of RSV hospitalizations in these populations. Currently, the American Academy of Pediatrics recommends this therapy for the prevention of severe infection in the population at higher risk. Economic evaluations have been conducted to determine the effectiveness of immunization, resulting favorable for palivizumab. Immunization in Mexico has resulted cost-effective in NBs under 32 gestation weeks. Mexican authorities should discuss the inclusion of palivizumab in their clinical guidelines., (Copyright: © 2020 Permanyer.)
