“Riesgos laborales y desempeño de las enfermeras en centro quirúrgico del hospital nacional Alberto Sabogal Sologuren – Essalud. Callao. 2020”

El presente trabajo indaga la relación entre los riesgos Laborales y el desempeño de las Enfermeras en Centro Quirúrgico del Hospital Nacional Alberto Sabogal Sologuren – Callao 2020, partiendo de un enfoque descriptivo no experimental, de corte trasversal en una muestra de treinta enfermeras que laboran en Centro Quirúrgico cumpliendo los criterios de inclusión e exclusión. Donde se encontró un análisis de correlación significativa (Pearson) entre el riesgo laboral y el desempeño P=Sig.=0,027<0,05. los riesgos laborales y la dimensión productividad se describe como P=Sig.=0,36. Lo que no sucede entre los riesgos laborales y la dimensión eficiencia, por lo tanto, si los riesgos laborales biológicos, químicos y ergonómicos al que se exponen las enfermeras se incrementa se verá afectada su eficiencia en el desempeño de sus funciones. Además, que existe una relación inversa o negativa entre los riesgos laborales y las dimensiones eficacia y la productividad, encontrándose mayor promedio en el riesgo biológico, seguido por el ergonómico y por último el químico, también se encontró, que el personal de enfermería refiere mantener posturas incómodas al realizar sus labores, trasladan cargas pesadas, y realizar movimientos repetitivos con las extremidades superiores. Conclusiones: Los riesgos laborales a los que están expuestos y afectan a las enfermeras de Centro quirúrgico son principalmente de riesgo biológico (media 40.46) representados por la manipulación y exposición a personas potencialmente contaminadas, luego riesgo ergonómico (media 30.76) por permanecer horas de pie cumpliendo funciones y finalmente riesgo químico (media 12.60) por estar expuestas a sustancias químicas como desinfectantes, preservantes y antisépticos. Así mismo del desempeño de las enfermeras en Centro quirúrgico más de la mitad de los entrevistados no pueden realizar con eficacia (media 16.73) sus funciones, aunque si con eficiencia (media 21.00) mitad de los entrevistados dicen no poder realizar con eficacia sus funciones, aunque si con eficiencia, ya que cuentan con la capacidad profesional, el conocimiento técnico para desenvolverse en su labor, y la mayoría logra cumplir con las metas asignadas y consideran su productividad de acorde con las políticas de la entida

Metabolic syndrome improvement in depression six months after prescribing simple hygienic-dietary recommendations

BACKGROUND: Changes in diet and exercise have been separately demonstrated to improve Depression, although scientific evidence available is scarce. In a previously published controlled study, just recommending these and other lifestyle measures (sleep restriction and sunlight exposure) in combination once, patients experienced improvements in their depressive symptoms six months later. In this sample, one in three depressive patients had metabolic syndrome (MetS) at baseline. First line treatment of MetS condition is hygienic-dietetic, being Mediterranean diet and exercise especially important. Therefore we analyzed if lifestyle recommendations also improved their metabolic profile. FINDINGS: During the sixth month evaluation, a smaller number of patients from the group receiving hygienic-dietary recommendations met MetS criteria comparing with the control group. CONCLUSIONS: This study suggests that costless lifestyle recommendations, such as exercise and Mediterranean diet, have the capacity to promote both mental and physical health in a significant proportion of depressive patients. Further research is needed to confirm or discard these preliminary findings

Ascariasis, Amebiasis and Giardiasis in Mexican children : distribution and geographical, environmental and socioeconomic risk factors

The aim of this study is to provide an overview of the geographical distribution of Ascariasis, Amebiasis and Giardiasis, and to identify specific geographical, socioeconomic and environmental factors that are associated with the incidence of these infections in Mexican children. We made use of publicly available data that was reported by federal organizations in Mexico for the year 2010. The contribution of geographical, socioeconomic and environmental factors to the incidence of infections was assessed by a multivariable regression model using a backwards selection procedure. A. lumbricoides incidence was associated with mean minimum temperature of the state, the state-wide rate of households without access to piped water and toilet, explaining 77% of the incidence of A. lumbricoides infections. Mean minimum precipitation in the state, the rate of households without access to a toilet, piped water and sewage system best explained (73%) the incidence of E. histolytica infections. G. lamblia infections were only explained by the latitude of the state (11%). In addition to the well-known socioeconomic factors contributing to the incidence of A. lumbricoides and E. histolytica we found that temperature and precipitation were associated with higher risk of infection

Arc-welding spectroscopic monitoring based on feature selection and neural networks

A new spectral processing technique designed for application in the on-line detection and classification of arc-welding defects is presented in this paper. A noninvasive fiber sensor embedded within a TIG torch collects the plasma radiation originated during the welding process. The spectral information is then processed in two consecutive stages. A compression algorithm is first applied to the data, allowing real-time analysis. The selected spectral bands are then used to feed a classification algorithm, which will be demonstrated to provide an efficient weld defect detection and classification. The results obtained with the proposed technique are compared to a similar processing scheme presented in previous works, giving rise to an improvement in the performance of the monitoring system

Phenotyping Type 2 Diabetes in Terms of Myocardial Insulin Resistance and Its Potential Cardiovascular Consequences: A New Strategy Based on 18F-FDG PET/CT

Cardiovascular risk; Myocardial insulin resistance; Type 2 diabetesRisc cardiovascular; Resistència miocàrdica a la insulina; Diabetis tipus 2Riesgo cardiovascular; Resistencia miocárdica a la insulina; Diabetes tipo 2Background: Systemic insulin resistance is generally postulated as an independent risk factor of cardiovascular events in type 2 diabetes (T2D). However, the role of myocardial insulin resistance (mIR) remains to be clarified. Methods: Two 18F-FDG PET/CT scans were performed on forty-three T2D patients at baseline and after hyperinsulinemic–euglycemic clamp (HEC). Myocardial insulin sensitivity (mIS) was determined by measuring the increment in myocardial 18F-FDG uptake after HEC. Coronary artery calcium scoring (CACs) and myocardial radiodensity (mRD) were assessed by CT. Results: After HEC, seventeen patients exhibited a strikingly enhancement of myocardial 18F-FDG uptake and twenty-six a marginal increase, thus revealing mIS and mIR, respectively. Patients with mIR showed higher mRD (HU: 38.95 [33.81–44.06] vs. 30.82 [21.48–38.02]; p = 0.03) and CACs > 400 (AU: 52% vs. 29%; p = 0.002) than patients with mIS. In addition, HOMA-IR and mIS only showed a correlation in those patients with mIR. Conclusions: 18F-FDG PET combined with HEC is a reliable method for identifying patients with mIR. This subgroup of patients was found to be specifically at high risk of developing cardiovascular events and showed myocardial structural changes. Moreover, the gold-standard HOMA-IR index was only associated with mIR in this subgroup of patients. Our results open up a new avenue for stratifying patients with cardiovascular risk in T2D.This research was funded by the Carlos III Health Institute and the European Regional Development Fund (PI16/02064 and PI20/01588) and AGAUR (2017SGR1303 and 2017SGR1144)

Defect Detection in Arc-Welding Processes by Means of the Line-to-Continuum Method and Feature Selection

Plasma optical spectroscopy is widely employed in on-line welding diagnostics. The determination of the plasma electron temperature, which is typically selected as the output monitoring parameter, implies the identification of the atomic emission lines. As a consequence, additional processing stages are required with a direct impact on the real time performance of the technique. The line-to-continuum method is a feasible alternative spectroscopic approach and it is particularly interesting in terms of its computational efficiency. However, the monitoring signal highly depends on the chosen emission line. In this paper, a feature selection methodology is proposed to solve the uncertainty regarding the selection of the optimum spectral band, which allows the employment of the line-to-continuum method for on-line welding diagnostics. Field test results have been conducted to demonstrate the feasibility of the solution

Specific micronutrient concentrations are associated with inflammatory cytokines in a rural population of Mexican women with a high prevalence of obesity

It has been recognised recently that obese individuals have lower concentrations of micronutrients and this may affect the concentrations of inflammatory cytokines. A cross-sectional study was carried out to evaluate the association of specific micronutrients' status with chronic inflammation caused by obesity in 280 women (36·1 (sd 7·5) years) from seven rural communities in Mexico. Measurements of weight, height and waist circumference were made on all women and body composition was determined by dual-energy X-ray absorptiometry. Concentrations of the cytokines IL-1, TNF-α, IL-6, IL-10 and IL-12, lipid profile, and the micronutrients Zn and vitamins A, C and E were determined in fasting blood samples. Ordered logistic regression models were used to determine associations between categorised cytokine levels and micronutrients. It was found that 80 % of women were overweight or obese, and had significantly higher concentrations of C-reactive protein than normal-weight women (P = 0·05). The risk of higher levels of TNF-α, IL-6, IL-10 and IL-12 was reduced significantly among women with higher Zn concentrations (OR 0·63, 95 % CI 0·42, 0·96, P = 0·03; OR 0·57, 95 % CI 0·39, 0·86, P = 0·025; OR 0·63, 95 % CI 0·41, 0·96, P = 0·04; OR 0·62, 95 % CI 0·41, 0·95, P = 0·03, respectively). Higher concentrations of vitamin A were slightly associated with reduced risks of higher levels of IL-1 and IL-12 (OR 0·97, 95 % CI 0·95, 0·99, P = 0·03; OR 0·97, 95 % CI 0·94, 0·99, P = 0·03, respectively); when adjusting for BMI, this association was lost. No associations were found between vitamin C or vitamin E:lipids concentrations and inflammatory cytokines. In conclusion, higher Zn concentrations are associated with reduced risks of higher concentration of inflammation markers in a population of women with a high prevalence of obesity

Shoc2/Sur8 protein regulates neurite outgrowth

This is an openaccess article distributed under the terms of the Creative Commons Attribution License.-- et al.The Shoc2 protein has been implicated in the positive regulation of the Ras-ERK pathway by increasing the functional binding interaction between Ras and Raf, leading to increased ERK activity. Here we found that Shoc2 overexpression induced sustained ERK phosphorylation, notably in the case of EGF stimulation, and Shoc2 knockdown inhibited ERK activation. We demonstrate that ectopic overexpression of human Shoc2 in PC12 cells significantly promotes neurite extension in the presence of EGF, a stimulus that induces proliferation rather than differentiation in these cells. Finally, Shoc2 depletion reduces both NGF-induced neurite outgrowth and ERK activation in PC12 cells. Our data indicate that Shoc2 is essential to modulate the Ras-ERK signaling outcome in cell differentiation processes involved in neurite outgrowth.GL, TG and LMD were recipients of fellowships from the Ministerio de Educación y Ciencia (MEC) (to GL, TG), and Fondo de Investigaciones Sanitarias (FIS) (to LMD).
