RIESGO CARDIOVASCULAR DEL PERSONAL DE ENFERMERÍA EN EL ÁREA QUIRÚRGICA

The aim of the present investigation was to determine cardiovascular risk factors, through the Framingham model, in the Infirmary Personnel in the surgical area of the Instituto Autónomo Hospital Universitario de Los Andes Merida-Venezuela. A descriptive, field, and cross section study was made, with a population of 43 nurses. The analysis and interpretation of the results were made by descriptive statistics. Test results and the laboratory analysis proved that since age was a non modifiable factor, most of them were in the young adulthood and mature adulthood periods with low cardiovascular risk. As regards modifiable factors, it was determined that more than half had Total Cholesterol at normal levels. In relation to HDL Cholesterol, according to laboratory tests the results showed a high percentage of low values such as <40 mg/dl, which translates as a possible increase of cardiovascular disease risk. As for smoking, more than half of the Infirmary Personnel declared not to have smoking habits. As for Arterial Pressure levels, it was determined that more than half of the professionals were within the normal parameters. When calculating the cardiovascular risk at 10 years, according to the Framingham Model, most of the nurses were located as “Very Low” and “Low” risk of suffering cardiovascular disease in 10 years. Nevertheless, 18.61% had a “Moderate” “High” and “Very High” risk of suffering cardiovascular diseases in the future, which requires proposing promotion and prevention activities aimed at improving the working and health conditions of the Infirmary Personnel and at diminishing cardiovascular risks that can affect their individual, family and community health.La presente investigación tuvo como objetivo determinar los factores de riesgo cardiovascular, a través del modelo de Framingham, en el Personal de Enfermería que labora en el área quirúrgica, Instituto Autónomo Hospital Universitario de Los Andes Mérida-Venezuela. Se realizó un estudio de tipo descriptivo, de campo y de corte transversal, con una población determinada por 43 enfermeras. El análisis e interpretación de los resultados se realizó con estadística descriptiva. Los resultados del test y los exámenes de laboratorio evidenciaron que siendo la edad un factor no modificable, la mayoría se encuentran en el periodo adultez joven y adultez madura con bajo riesgo cardiovascular. Con respecto a los factores modificables, se determinó que del Colesterol Total más de la mitad presentó niveles normales. En relación al Colesterol HDL, según los exámenes de laboratorio los resultados reflejaron: un alto porcentaje mostró cifras bajas, es decir <40 mg/dl, lo cual se traduce en un posible aumento del riesgo a enfermedad cardiovascular. En cuanto al tabaquismo, más de la mitad del Personal de Enfermería manifestó no poseer hábitos tabáquicos. En lo referente a la medición de la Presión Arterial, se encontró que más de la mitad de los profesionales se encuentran en parámetros normales. Al calcular el riesgo cardiovascular a 10 años, según el Modelo de Framingham, la mayoría de las enfermeras, se ubicaron en “Muy Bajo” y “Bajo” riesgo de padecer enfermedad cardiovascular a 10 años. Sin embargo, el 18,61 % tienen un riesgo “Moderado”, “Alto” y “Muy Alto” de padecer en el futuro enfermedades cardiovasculares, lo que requiere de la propuesta de actividades de promoción y prevención, tendientes a mejorar las condiciones de trabajo y salud del Personal de Enfermería, orientadas a disminuir los riesgos cardiovasculares que puedan afectar su salud individual, familiar y en la comunidad

An Ecological Alternative to Snodgrass & Vanderwart: 360 High Quality Colour Images with Norms for Seven Psycholinguistic Variables

This work presents a new set of 360 high quality colour images belonging to 23 semantic subcategories. Two hundred and thirty-six Spanish speakers named the items and also provided data from seven relevant psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived from Internet search hits. Apart from the high number of variables evaluated, knowing that it affects the processing of stimuli, this new set presents important advantages over other similar image corpi: (a) this corpus presents a broad number of subcategories and images; for example, this will permit researchers to select stimuli of appropriate difficulty as required, (e.g., to deal with problems derived from ceiling effects); (b) the fact of using coloured stimuli provides a more realistic, ecologically-valid, representation of real life objects. In sum, this set of stimuli provides a useful tool for research on visual object-and word- processing, both in neurological patients and in healthy controls

New regulations regarding Postgraduate Medical Training in Spain: perception of the tutor's role in the Murcia Region

<p>Abstract</p> <p>Background</p> <p>Recently introduced regulatory changes have expanded the Tutor role to include their primary responsibility for Postgraduate Medical Training (PMT). However, accreditation and recognition of that role has been devolved to the autonomic regions. The opinions of the RT may be relevant to future decisions;</p> <p>Methods</p> <p>A comprehensive questionnaire, including demographic characteristics, academic and research achievement and personal views about their role, was sent to 201 RTs in the Murcia Region of Spain. The responses are described using median and interquartile ranges (IQR);</p> <p>Results</p> <p>There were 147 replies (response rate 73%), 69% male, mean age 45 ± 7 yrs. RTs perception of the residents' initial knowledge and commitment throughout the program was 5 (IQR 4-6) and 7 (IQR 5-8), respectively. As regards their impact on the PMT program, RTs considered that their own contribution was similar to that of senior residents. RTs perception of how their role was recognised was 5 (IQR 3-6). Only 16% did not encounter difficulties in accessing specific RT training programs. Regarding the RTs view of their various duties, supervision of patient care was accorded the greatest importance (64%) while the satisfactory completion of the PMT program and supervision of day-to-day activities were also considered important (61% and 59% respectively). The main RT requirements were: a greater professional recognition (97%), protected time (95%), specific RT training programs (95%) and financial recognition (86%);</p> <p>Conclusions</p> <p>This comprehensive study, reflecting the feelings of our RTs, provides a useful insight into the reality of their work and the findings ought to be taken into consideration in the imminent definitive regulatory document on PMT.</p

Synthesis and characterization of new aromatic esters based on 4,16-pregnadiene-6,20-dione skeleton

A series of new aromatic esters based on 4,16-pregnadiene-6,20-dione skeleton, namely 3β-benzoyloxy-4,16-pregnadiene-6,20-dione and 3β-furoyloxy-4,16-pregnadiene- 6,20-dione, which may be good inhibitors for the 5α-reductase enzyme and show high antiandrogenic activity, were synthesized starting from diosgenin. The structures of the steroids were characterized by elemental analysis, 1H NMR, 13C NMR, IR and mass spectrum. Single crystal X-ray diffraction measurement on one of the new compounds, 3β-(p-methoxybenzoyloxy)-4,16-pregnadiene-6,20-dione revealed that the A, B, C, and D ring adopted half chair, distorted chair, distorted chair, and distorted envelope conformation, respectively. The molecules in the crystal were packed face-to-face at the normal van der Waals distances

Sexual (Dis)satisfaction and Its Contributors Among People Living with HIV Infection in Sweden

Earlier research reports lower sexual satisfaction among people living with HIV (PLHIV) compared to HIV-negative persons. A number of psychosocial factors directly associated with sexual dissatisfaction have been identified. Little is known about sexual satisfaction and their contributors among PLHIV in Sweden. The aim of this study was to examine direct and indirect effects of variables within sociodemographic, clinical HIV-related, psychological, and sexual domains on sexual(dis)satisfaction among PLHIV in Sweden. Data for this study was derived from a national representative, anonymous survey among PLHIV conducted in 2014 (n=1096). Statistical analysis included four steps: descriptive analyses, identification of variables associated with sexual (dis)satisfaction, identification of variables associated with those contributors of sexual (dis)satisfaction, and a path model integrating all these analyses. A total of 49% of participants reported being sexually dissatisfied and no significant differences were observed when non-heterosexual men, heterosexual men and women were compared. Among women, a negative change in sex life after HIV diagnosis and distress with orgasmic difficulties were directly associated with sexual dissatisfaction. For men, hopelessness, high HIV stigma, sexual inactivity in the last 6 months, and a negative change in sex life after HIV diagnosis were directly associated with sexual dissatisfaction. Path analyses showed in both men and women significant indirect association between not being involved in an intimate relationship, lower self-reported CD4 cell counts, and perceiving obligation to disclose HIV status to sexual partners as a barrier to look for a long-term partner and sexual dissatisfaction. Our results show that despite good treatment outcomes, the HIV diagnosis has a negative bearing on sexual satisfaction. The need for gender-tailored interventions and clinical implications of these findings are discussed

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

Complex evolutionary history of the Mexican stoneroller Campostoma ornatum Girard, 1856 (Actinopterygii: Cyprinidae)

<p>Abstract</p> <p>Background</p> <p>Studies of the phylogeography of Mexican species are steadily revealing genetic patterns shared by different species, which will help to unravel the complex biogeographic history of the region. <it>Campostoma ornatum </it>is a freshwater fish endemic to montane and semiarid regions in northwest Mexico and southern Arizona. Its wide range of distribution and the previously observed morphological differentiation between populations in different watersheds make this species a useful model to investigate the biogeographic role of the Sierra Madre Occidental and to disentangle the actions of Pliocene tecto-volcanic processes <it>vs </it>Quaternary climatic change. Our phylogeographic study was based on DNA sequences from one mitochondrial gene (<it>cytb</it>, 1110 bp, n = 285) and two nuclear gene regions (S7 and RAG1, 1822 bp in total, n = 56 and 43, respectively) obtained from 18 to 29 localities, in addition to a morphological survey covering the entire distribution area. Such a dataset allowed us to assess whether any of the populations/lineages sampled deserve to be categorised as an evolutionarily significant unit.</p> <p>Results</p> <p>We found two morphologically and genetically well-differentiated groups within <it>C. ornatum</it>. One is located in the northern river drainages (Yaqui, Mayo, Fuerte, Sonora, Casas Grandes, Santa Clara and Conchos) and another one is found in the southern drainages (Nazas, Aguanaval and Piaxtla). The split between these two lineages took place about 3.9 Mya (CI = 2.1-5.9). Within the northern lineage, there was strong and significant inter-basin genetic differentiation and also several secondary dispersal episodes whit gene homogenization between drainages. Interestingly, three divergent mitochondrial lineages were found in sympatry in two northern localities from the Yaqui river basin.</p> <p>Conclusions</p> <p>Our results indicate that there was isolation between the northern and southern phylogroups since the Pliocene, which was related to the formation of the ancient Nazas River paleosystem, where the southern group originated. Within groups, a complex reticulate biogeographic history for <it>C. ornatum </it>populations emerges, following the taxon pulse theory and mainly related with Pliocene tecto-volcanic processes. In the northern group, several events of vicariance promoted by river or drainage isolation episodes were found, but within both groups, the phylogeographic patterns suggest the occurrence of several events of river capture and fauna interchange. The Yaqui River supports the most diverse populations of <it>C. ornatum</it>, with several events of dispersal and isolation within the basin. Based on our genetic results, we defined three ESUs within <it>C. ornatum </it>as a first attempt to promote the conservation of the evolutionary processes determining the genetic diversity of this species. They will likely be revealed as a valuable tool for freshwater conservation policies in northwest Mexico, where many environmental problems concerning the use of water have rapidly arisen in recent decades.</p
