Hábitos nutricionais, atividade física, composição corporal e estresse entre policiais militares operacionais e administrativos

Military police activity is a dangerous, stressful occupation that poses health risks. Nutritional habits, physical activity, body composition and perceived stress, in addition to being interrelated, influence components of professional performance, such as work motivation, general self-efficacy and absenteeism. The objective was to compare nutritional habits, physical activity, body mass index and perceived stress of military police officers working in operational and administrative services, of both sexes, and to investigate the correlation between these variables. The Mann-Whitney U test was used for the comparative analysis and, for the correlational study, the Pearson correlation coefficient. Perceived stress and physical activity were inversely correlated (r=-0.268; p<0.001). Nutritional habits correlated significantly: with physical activity (r=0.381; p<0.001), directly; and, conversely, body mass index (r=0.256; p<0.001) and perceived stress (r=-0.201; p<0.01). Military police officers from the operational service had significantly higher body mass index (U=3695; p<0.001) and physical activity (U=3776; p<0.001) than their counterparts from the administrative service. Men had significantly higher body mass index (U=1333; p<0.001) and physical activity (U=2205; p<0.01) than women, who had significantly higher stress levels than men (U=1927; p<0.001). The correlations and significant differences observed point to the need to implement personnel and health management policies aimed at improving the lifestyle, body composition and stress of military police officers. Study limitations and future directions are discussed.La actividad de la policía militar es una ocupación peligrosa y estresante que presenta riesgos para la salud. Hábitos alimentarios, actividad física, composición corporal y estrés percibido, además de estar interrelacionados, influyen en componentes del desempeño profesional, como motivación para el trabajo, autoeficacia general y ausentismo. El objetivo fue comparar hábitos nutricionales, actividad física, índice de masa corporal y estrés percibido de policías militares que trabajan en servicios operativos y administrativos, de ambos sexos, e investigar la correlación entre estas variables. Para el análisis comparativo se utilizó la prueba U de Mann-Whitney y, para el estudio correlacional, el coeficiente de correlación de Pearson. Estrés percibido y actividad física se correlacionaron inversamente (r=-0,268; p<0,001). Hábitos nutricionales correlacionaron significativamente: con actividad física (r=0,381; p<0,001), directamente; y, por el contrario, con índice de masa corporal (r=0,256; p<0,001) y estrés percibido (r=-0,201; p<0,01). Los policías militares del servicio operativo presentaron índice de masa corporal (U=3695; p<0,001) y actividad física (U=3776; p<0,001) significativamente mayores que sus homólogos del servicio administrativo. Hombres tenían un índice de masa corporal significativamente mayor (U=1333; p<0,001) y actividad física (U=2205; p<0,01) que las mujeres, quienes tenían niveles de estrés significativamente más altos que los hombres (U=1927; p<0,001). Las correlaciones y diferencias significativas observadas apuntan a necesidad de implementar políticas de gestión de personal y salud dirigidas a mejorar el estilo de vida, composición corporal y estrés de los policías militares. Se discuten limitaciones del estudio y direcciones futuras.A atividade policial militar é uma ocupação perigosa, estressante e que impõe riscos à saúde.

Score CTo-aBCDE : um novo score preditor de sucesso nas CTOs

© 2020 Sociedade Portuguesa de Cardiologia. Published by Elsevier España, S.L.U. This is an open access article under the CC-BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/).Introduction: Patient selection for percutaneous coronary intervention (PCI) in chronic total occlusions (CTOs) is crucial to procedural success. Our aim was to identify independent predictors of success in CTO PCI in order to create an accurate score. Methods: In a single-center observational registry of CTO PCI, demographic and clinical data and anatomical characteristics of coronary lesions were recorded. Linear and logistic regression analysis were used to identify predictors of success. A score to predict success was created and its accuracy was measured by receiver operating curve analysis. Results: A total of 377 interventions were performed (334 patients, age 68±11 years, 75% male). The success rate was 65% per patient and 60% per procedure. Predictors of success in univariate analysis were absence of active smoking (OR 2.02, 95% CI 1.243-3.29; p=0.005), presence of tapered stump (OR 5.2, 95% CI 2.7-10.2; p8 with high probability (95%). Conclusion: In our sample only anatomical characteristics were predictors of success. The creation of a score to predict success, with good accuracy, may enable selection of cases that can be treated by any operator, those in which a dedicated operator will be desirable, and those with an extremely low probability of success, which should be considered individually for conservative management, surgical revascularization or PCI by a team experienced in CTO.info:eu-repo/semantics/publishedVersio

Phenolic compounds from Rosemary (Rosmarinus officinalis L.) attenuate oxidative stress and reduce blood cholesterol concentrations in diet-induced hypercholesterolemic rats

Abstract\ud \ud \ud \ud Background\ud \ud Phenolic compounds combine antioxidant and hypocholesterolemic activities and, consequently, are expected to prevent or minimize cardiometabolic risk.\ud \ud \ud \ud Methods\ud \ud To evaluate the effect of an aqueous extract (AQ) and non-esterified phenolic fraction (NEPF) from rosemary on oxidative stress in diet-induced hypercholesterolemia, 48 male 4-week old Wistar rats were divided into 6 groups: 1 chow diet group (C) and 5 hypercholesterolemic diet groups, with 1 receiving water (HC), 2 receiving AQ at concentrations of 7 and 140 mg/kg body weight (AQ70 and AQ140, respectively), and 2 receiving NEPF at concentrations of 7 and 14 mg/kg body weight (NEPF7 and NEPF14, respectively) by gavage for 4 weeks.\ud \ud \ud \ud Results\ud \ud In vitro, both AQ and NEPF had remarkable antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH●) assay, which was similar to BHT. In vivo, the group that received AQ at 70 mg/kg body weight had lower serum total cholesterol (−39.8%), non-HDL-c (−44.4%) and thiobarbituric acid reactive substance (TBARS) levels (−37.7%) compared with the HC group. NEPF (7 and 14 mg/kg) reduced the tissue TBARS levels and increased the activity of tissular antioxidant enzymes (superoxide dismutase, catalase and glutathione peroxidase). Neither AQ nor NEPF was able to ameliorate the alterations in the hypercholesterolemic diet-induced fatty acid composition in the liver.\ud \ud \ud \ud Conclusions\ud \ud These data suggest that phenolic compounds from rosemary ameliorate the antioxidant defense in different tissues and attenuate oxidative stress in diet-induced hypercholesterolemic rats, whereas the serum lipid profile was improved only in rats that received the aqueous extract.This investigation was supported by grants 08/51333-1 (Afonso MS) and 08/54319-0 (Mancini-Filho, J) from the Fundação de Amparo a Pesquisa do Estado de São Paulo (FAPESP), Brazil.

A well-kept treasure at depth: precious red coral rediscovered in Atlantic deep coral gardens (SW Portugal) after 300 years

The highly valuable red coral Corallium rubrum is listed in several Mediterranean Conventions for species protection and management since the 1980s. Yet, the lack of data about its Atlantic distribution has hindered its protection there. This culminated in the recent discovery of poaching activities harvesting tens of kg of coral per day from deep rocky reefs off SW Portugal. Red coral was irregularly exploited in Portugal between the 1200s and 1700s, until the fishery collapsed. Its occurrence has not been reported for the last 300 years.info:eu-repo/semantics/publishedVersio

ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe
