    Abstract El presente estudio se llevó a cabo con el objetivo de determinar el efecto de la fertilización con nitrógeno (N) y la densidad de población (D), sobre la acumulación y distribución de materia seca (MS) en la planta, así como la biomasa total (BT), el rendi- miento (RG) y sus componentes, en los cultivares de girasol Victoria Mejorado y Sunbred. La siembra se efectuó el 3 de mayo de 2016 en Montecillo, Estado de México, México, la cual es una zona de clima templado. El diseño experimental fue de bloques al azar con arreglo en parcelas subdivididas y cuatro repeticiones. Los resultados indican diferencias no significativas para BT y RG entre cultivares. La fertilización con N y el aumento en D elevaron la eficiencia en el uso del agua, la acumulación de MS en los órganos de la plan- ta, la BT, el RG y el número de granos, pero no afectaron los días a etapas fenológicas, el índice de cosecha o el tamaño del grano. La BT y el RG con N fue de 1,232 y 232 g m-2 y en D alta fue de 1,220 y 219 g m-2, respectivamente.

    Abstract Background: The aim of the present study was to determine the relationship between the quality of life of patients on renal replacement therapy and the Symptomatology they presented. Methods: Cross-sectional descriptive observational study: quality of life was assessed by means of the KDQOL-SF questionnaire, Symptomatology by the Palliative Care Outcome Scale-Symptoms Renal questionnaire, and sociodemographic and clinical data of patients in the Hemodialysis Unit (HD) of the Hospital General Universitario de Ciudad Real (HGUCR) by means of personal interviews and clinical history data. Results : A total of 105 patients participated in the study, 63 (60.57%) men and 42 (40.38%) female. The mean age was 62.5 dt (14.84) years. Of these, 43 (41%) were on peritoneal dialysis and 62 (59%) were on hemodialysis. The mean quality of life score was 44.89 dt (9.73). People on hemodialysis treatment presented a better quality of life than those on PD treatment: 49.66 dt (9.73) vs. 38.13 dt (9.12) t = 7.302, p < 0.001. A higher score on the symptom impairment scale (post-renal) correlated with worse scores on the total quality of life score: r = −0.807, p < 0.001. It was observed that those who improved the distress symptom scored better on the total quality of life questionnaire: 50.22 dt (8.44) vs. 46.42 dt (9.05), p < 0.001. Conclusions : The presence and management of the large number of symptoms that appear as side effects, such as distress or depression, could determine changes in some components of quality of life.

    Abstract La aplicación de nitrógeno (N) y su efecto en el cultivo de ajo, ha sido objeto de investigaciones en cultivares, condiciones de crecimiento y respuesta variable en el rendimiento. No obstante, el estudio sobre la fenología, radiación interceptada, rendimiento y la eficiencia agronómica del N son limitados y este fue el objetivo del presente trabajo. La investigación fue conducida durante el ciclo otoño-invierno 2016-2017, en el campo experimental del Colegio de Postgraduados, campus Montecillo, Texcoco, Estado de México, México (19° 29’ N y 98° 53’ O y 2250 m de altitud), clima templado y suelo arcillo-limoso; bajo condiciones de riego. La siembra del cultivar criollo “Pata de mula” fue el 24 de octubre de 2016 y la cosecha a los 150 días después de la siembra. El patrón de siembra (arreglo topológico) fue de 15 × 15 cm, que generó una población de 44.3 plantas m-2. Los tratamientos consistieron en la aplicación 0, 100, 200, 300 kg N ha-1. El diseño experimental fue bloques al azar con cuatro repeticiones. Los resultados indican que el suministro de nitrógeno no afectó los días a ocurrencia de las fases fenológicas, pero ocasionó aumento en la radiación interceptada, el número de dientes, el tamaño del bulbo, el peso de la planta y del bulbo. La distribución de materia seca en la planta y el índice de cosecha no fueron afectados por la aplicación de N. Con N200 y N300 se obtuvo el mayor rendimiento de bulbo. Se considera que 200 kg N ha-1 es la dosis óptima para el cultivo en la región de estudio, con la cual se obtiene la mayor eficiencia agronómica del nitrógeno.

    Abstract Severe mental disorder (SMD) produces a significant functional limitation that affects the performance of daily activities. The occupational therapist intervenes on this limitation by seeking greater autonomy of these patients through specific activities. This study aims to identify the main limitations of people with SMD and to examine whether an occupational intervention has any effect in helping to overcome or ameliorate these limitations. A quasi-experimental study including 103 participants was carried out. An evaluation using the World Health Organization Disability Assessment Schedule (WHODAS 2.0) questionnaire was performed before and after the intervention. Within the activity program, those with a higher attendance rating during cognitive stimulation, cooking workshop, therapeutic walks, relaxation, and creative activities were mainly men. Both patients and professionals indicated that Understanding and Communicating, Participation in Society, and Activities of Daily Living were the main perceived limitations. Upon discharge, patients and professionals reported positive outcomes. The intervention programs carried out by occupational therapy, along with the other aspects of the treatment that SMD patients received, played an important part in improving the performance and occupational interests of these patients.

    Abstract Background: Healthcare workers are continuously exposed to a high level of stress, especially emergency department professionals. In the present research, we aimed to determine the internal consistency and validity of the Stress Factors and Manifestations Scale for in-hospital and out-of-hospital emergency workers. Methods: A quantitative, prospective, cross-sectional, and observational study including 269 emergency service professionals. Results: The scale was composed of 21 items, with a Cronbach’s α value of 0.908. The hospital workers (38.4 ± 10.8 vs. 35.1 ± 9.9, p = 0.014) and women (39.3 ± 11.4 vs. 34.2 ± 8.6, p < 0.001) had higher levels of stress. The sensitivity, specificity, and predictive values of the scale were adequate. Conclusion: In the present study, including in-hospital and out-of-hospital emergency workers, the Stress Factors and Manifestations Scale presented appropriate usefulness, internal consistency, and validity, with optimal predictive ability. Higher levels of anxiety, female gender, being less optimistic, and working in hospital emergency departments were related to increased stress levels. Further studies are warranted to validate our results and potentially extend the Stress Factors and Manifestations Scale to other contexts.

    Abstract The purpose of this study was to determine the prevalence of sleep quality and to investigate variables predicting the risk of poor sleep quality in public workers from Murcia (Spain). A cross-sectional and prospective study was conducted from October 2013 to February 2016 in 476 public workers. The Pittsburgh Sleep Quality Index was used to measure the quality of sleep, and the reduced scale of the Horne and Österberg Morningness–Eveningness Questionnaire was applied to analyze the circadian typology. The predictive variables of self-reported poor sleep quality were identified by multivariate logistic regression. No significant differences were found according to sex in the overall sleep quality scores (5 ± 2.9 versus 5.1 ± 3, p = 0.650), but there were in the duration of sleep. Three percent of females slept <5 hours compared to 2% of men ( p = 0.034). Fixed morning shifts (OR = 1.9, 95% CI 1.3–3.1; p = 0.007) and evening chronotypes (OR = 1.6, 95% CI 1.0–2.3; p = 0.017) were independent predictors of suffering from poor sleep quality. In conclusion, the frequency of self-reported poor sleep quality among public workers from Murcia was 37.4%. Being a public worker with a fixed morning shift and having an evening chronotype demonstrated to be associated with the quality of sleep.

    Abstract Stress is common in all work environments. Technostress and the difficulty of separating the family arena from the work environment are some of the new and emerging risks faced by companies, employees and society in general. Most of the available instruments for measuring stress in workers have been focused on education professionals and healthcare workers. Therefore, it is necessary to validate simple and friendly-use tools to detect stress levels in public workers. The aim of this study was to determine the internal consistency of an adapted version of the Student Stress Inventory-Stress Manifestations (SSI-SM) for public employees and to determine if high-stress levels are related to personal and work-related factors. A cross-sectional and descriptive study was conducted from October 2016 to February 2019 including 468 Spanish public workers based in Murcia. An adapted version of the SSI-SM was administered and data on personal and work-related factors were collected. Results showed that all of the factors had Cronbach’s α over 0.700, and no items need to be deleted due to correlations with the factor exceeding 0.300. Factor 1, “Self-concept”, has a Cronbach’s α of 0.868, with values of 15.62 ± 4.99; factor 2, “Sociability”, Cronbach’s α: 0.853, with mean values of 13.33 ± 4.17; factor 3, “Somatization” , Cronbach’s α: 0.704, mean value of 5.35 ± 1.90 and: factor 4, “Uncertainty”, Cronbach’s α: 0.746, with a mean value of 8.19 ± 2.51. In conclusion, the internal consistency of the adapted SSI-SM for public employees with different work positions and shifts has been validated and determined. This study provides a useful tool for the early detection of stress in public employees and may be potentially useful for preventing the harmful consequences of stress.

    Abstract University students are predisposed to stress, which could be even higher in Nursing students since they are directly related to the COVID-19 pandemic given their health training and area of knowledge. Our purpose was to assess the stress levels of Nursing students before and during lockdown due to the COVID-19 pandemic in Murcia (Spain), its influence on taking an online exam and how it was affected by physical exercise. This was an observational and prospective study including Nursing students from the second year of the Nursing Degree from 3 February to 23 April 2020. Three measurements were performed: one before lockdown and two during lockdown. Stress increased substantially during lockdown. Financial, family or emotional problems, as well as physical exercise, also increased. Indeed, at 40 days of lockdown, those students with financial, family or emotional problems, and less physical exercise reported significantly higher stress levels. In addition, those who passed the online exam had lower stress levels compared to those who failed. In conclusion, during lockdown, stress in Nursing students increased. This could be triggered by students’ personal problems, and physical exercise may be used as a way to reduce stress. Academic performance was better in those students reporting less stress.

    Abstract El análisis de crecimiento es una aproximación cuantitativa de descripción e interpretación del desarrollo vegetal, determinado por condiciones genético-ambientales. El objetivo fue conocer el desarrollo en 4 cultivares de sorgo forrajero (caña dulce, Silo miel, Esmeralda y Fortuna) mediante a acumulación de biomasa (BT), altura de planta (AP), nudos por planta (NNP), índice de área foliar (IAF), tasa de crecimiento del cultivo (TCC) y tasa de asimilación neta (TAN), con el fin de determinar la producción y momento óptimo de corte, bajo condiciones de secano en el Altiplano Central, Colegio de Postgraduados, Campus Montecillo, Texcoco, Estado de México, México. El diseño experimental fue bloques al azar en parcelas divididas, con arreglo factorial. Por muestreo, se tomó una planta de cada cultivar con 4 repeticiones y se midió BT, AP, NNP y IAF a 115 días después de la siembra (dds). La caña dulce presentó mayor AP (202 cm), IAF (3,8) y BT (14,35 t.ha-1); en contraste, Fortuna presentó menor AP (90 cm), BT (3,96 t.ha-1) e IAF (2,1). La caña dulce en el periodo 25-55 dds, presentó mayores TCC (24,2 gm-2d-1) y TAN (10,2 gm-2d-1); por su parte Fortuna presentó menor TCC (5 gm-2d-1) y TAN (5,51 gm-2d-1). La BT se correlacionó positivamente con AP, IAF, TCC (p≤0,001) y TAN, con TCC (p≤0,001). El mejor cultivar para producción de forraje y condiciones del estudio fue Caña dulce; lo anterior, debido a que presentó los mejores parámetros a lo largo del ciclo del cultivo para AP, NNP, BT, IAF, TCC y TAN. La máxima acumulación de biomasa se observó a 115 dds y coincide con la etapa fenológica reproductiva en inicio de floración, con plantas de 200 cm de longitud; posteriormente, tanto TAN (0,1 gm-2d-1) como el IAF (3,9), TCC (0,3 gm-2d-1) disminuyeron considerablemente; por tanto, el momento óptimo de corte es a 115 dds en el cultivar: Caña dulce.

    Abstract El frijol chino (FC) se utiliza en alimentación humana y se cultiva en espaldera viva de maíz, pero, son escasos los estudios sobre arreglos topológicos adecuados. En este sistema, la biofertilización (BIO) y fertilización foliar (FF) podrían complementar la nutrición. En Huitzuco, Guerrero, México, durante el periodo lluvioso se sembró FC tipo guía en espaldera de maíz a 80 (D8) y 160 cm (D16) de distancia entre hileras (D), con y sin BIO (B y SB) y con y sin FF (F y SF), para determinar los efectos de D, BIO y FF sobre el rendimiento y calidad nutrimental de vainas. La emergencia del FC se presentó a los 6 días después de la siembra (dds), la floración a los 58 dds, el primer corte de vaina a los 70 dds y el último a los 110 dds. El mayor rendimiento de vaina se logró con D8-B-F (851 g m-2), seguido por D8-SB-F (758 g m-2) y D16-B-F (657 g m-2), con los que se generó la más alta concentración de minerales (6,5%) y proteínas (28,1%), y la menor de carbohidratos solubles y fibras. El mayor rendimiento y calidad nutricional de vaina verde se obtuvo con D8-B-F.
