BACKGROUND: Increased blood pressure is the biggest contributor to the global burden of disease and mortality. Data suggest that less than half of the population with hypertension is aware of it. May Measurement Month was initiated to raise awareness of the importance of blood pressure and as a pragmatic interim solution to the shortfall in screening programmes. METHODS: This cross-sectional survey included volunteer adults (≥18 years) who ideally had not had their blood pressures measured in the past year...

Decision making in advanced Amyotrophic Lateral Sclerosis (ALS) patients keeps on being a controversial issue. The aim of this work is to discuss ethical implications of withdrawing respiratory support treatment in patients with ALS. Through a bibliographic search on Pubmed database (2010-2016) we investigated whether or not the use of Non-Invasive Ventilation (NIV) and Mechanical Ventilation (MV) would increase survival and quality of life. We included 38 review articles. From these papers, results and ethical implications of initiating and mainly withdrawing respiratory support were analyzed...

The identification of Aedes aegypti breeding hotspots in urban areas is crucial for the rational design of control strategies against this disease vector. Remote sensing and geographic information systems offer valuable tools for mapping habitat suitability of a given area. However, predicting species occurrences by means of probability distribution maps based on transversal entomological surveys has limited utility for local authorities. The aim of the present study was to carefully examine the temporal evolution of the number of houses infested with immature stages of Ae...

Two experiments were performed to determine if the tail has a role: 1) in proceptive behavior, and 2) in facilitating copulation in hair sheep. The movements and position of the tail of estrous and non-estrous ewes in response to male courtship were compared in the first study. In the second study, the courtship of rams and mating behavior directed towards tailed or tail-docked, in estrus or diestrus ewes, were compared. Both experiments were conducted with restrained ewes during 3 min assessment periods...

St.Louis encephalitis virus (SLEV) is an emerging human pathogen flavivirus in Argentina. Recently, it has reemerged in the United States. We evaluated the role as amplifying host of six resident bird species and analyzed their capacity as host during the 2005 encephalitis outbreak of SLEV in Córdoba. Eared dove, picui ground dove, and house sparrow were the three species with highest host competence index. At a city level, eared doves and picui ground doves were the most important amplifying hosts during the 2005 SLEV human outbreak in Córdoba city...

BACKGROUND: Aortic aneurysm (AA) is a pathology with high morbidity and mortality. The management can be expectant, surgical, or through endovascular repair (EVAR). In Latin America the incidence of AA has increased and the analysis of therapeutic options, especially if they are expensive, is fundamental. OBJECTIVE: To analyze available evidence on the effectiveness, safety and coverage policies of the EVAR. METHODOLOGY: Panoramic review in the main bibliographical bases (MEDLINE, LILACS, EMBASE, Cochrane Library, DARE) and generic internet searchers, main health technology assessment (HTA) agencies and health insurance companies...

Background: The scanner does not measure the dental surface continually. Instead, it generates a point cloud, and these points are then joined to form the scanned object. This approximation will depend on the number of points generated (resolution), which can lead to low accuracy (trueness and precision) when fewer points are obtained. The purpose of this study is to determine the resolution of four intraoral digital imaging systems and to demonstrate the relationship between accuracy and resolution of the intraoral scanner in impressions of a complete dental arch...

The main purpose of this paper is to present a system to detect extrusion failures in fused deposition modelling (FDM) 3D printers by sensing that the filament is moving forward properly. After several years using these kind of machines, authors detected that there is not any system to detect the main problem in FDM machines. Authors thought in different sensors and used the weighted objectives method, one of the most common evaluation methods, for comparing design concepts based on an overall value per design concept...

The tropical forage legume Stylosanthes humilis is naturally distributed in the acidic soils of the tropics. However, data concerning the role of low soil pH in the control of S. humilis seed germination remains limited. Recently, we have demonstrated that acidic soil triggers increased ethylene production during germination of S. humilis seeds, concomitantly with higher root penetration into the soil. Our finding points an important role of low soil pH as a signal allowing penetration of root in the soil through interaction with the ethylene signalling pathway...

The major histocompatibility complex is directly involved in the immune response, and thus the genes coding for its proteins are useful markers for the study of genetic diversity, susceptibility to disease (autoimmunity and infections), transplant medicine, and pharmacogenetics, among others. The polymorphism of the system also allows researchers to use it as a proxy for population genetics analysis, such as genetic admixture and genetic structure. In order to determine the immunogenetic characteristics of a sample from the northern part of Mexico City and to use them to analyze the genetic differentiation from other admixed populations, including those from previous studies of Mexico City population, we analyzed molecular typing results of donors and patients from the Histocompatibility Laboratory of the Central Blood Bank of the Centro Médico Nacional La Raza selected according to their geographic origin...

Background: A new nonavalent human papillomavirus (HPV) vaccine that includes genotypes 6/11/16/18/31/33/45/52/58 has been recently approved in Spain. A previous study has shown that attributable fraction of HPV related diseases in Spain is consistent with that reported in European and global studies. The aim of the present study was to estimate the annual direct costs associated to the following HPV-related diseases: genital warts, high grade precancerous lesions and cancer of cervix, vulva, vagina, anus and penis and head and neck cancer, caused by genotypes included in the nonavalent (9vHPV) and quadrivalent vaccines (4vHPV), in Spanish men and women...

BACKGROUND: Neonatal sepsis remains worldwide one of the leading causes of morbidity and mortality in both term and preterm infants. Lower mortality rates are related to timely diagnostic evaluation and prompt initiation of empiric antibiotic therapy. Blood culture, as gold standard examination for sepsis, has several limitations for early diagnosis, so that sepsis biomarkers could play an important role in this regard. This study was aimed to compare the value of the two biomarkers presepsin and procalcitonin in early diagnosis of neonatal sepsis...

A calibration chamber has been designed and employed for the simple and easy determination of uptake sampling rate (RS ) of volatile organic compounds (VOCs) from air using passive samplers. A flow of clean air was continuously spiked, at a constant VOC concentration, by the microinjection of a standard solution by means of a T-type tube. The developed system allowed the complete evaporation at room temperature of the standard solution in acetone and the air concentration of VOCs was easily controlled by the regulation of the clean air flow, the standard solution concentration and its flow...
