Introducción: la pandemia del síndrome respiratorio agudo grave Sars-CoV-2 causado por un coronavirus que se denominó COVID-19, revolucionado de forma importante los estilos de vida de la población universitaria, la población requiere de conocimientos y tener buenas prácticas para evitar el contagio por medio del autocuidado, los retos y adaptaciones del aprendizaje en un entorno virtual conlleva a formas de vida modificadas relacionadas con un incremento de sedentarismo, estrés y temor al contagio, entre otros. Objetivo: determinar los estilos de vida saludables, conocimientos y prácticas de cuidado por causa de la pandemia de COVID-19 en estudiantes de enfermería de la Universidad de Morelos. Material y métodos: estudio descriptivo, transversal, con participación de 265 estudiantes. Se aplicaron los cuestionarios en línea HPLP-II, valora estilos de vida y cuestionario ex profeso para conocimientos, práctica del cuidado durante la pandemia, durante septiembre a octubre 2020. Resultados: conocimientos: los estudiantes sólo reconocen la sintomatología respiratoria, mencionan que practican sólo algunas de las medidas de seguridad, se obtuvo asociaciones entre conocimientos, práctica y estilos de vida p=<.05. Discusión: estudios en Perú, Colombia, España y México, revelan resultados semejantes y significativos, relacionan calidad de vida y estilos de vida, conocimientos, actitudes y prácticas adecuadas, así como actitudes positivas de estudiantes universitarios ante la COVID-19. Conclusión: la población universitaria es vulnerable al contagio, aún no han dimensionado la magnitud del problema que se vive, cuentan con escasos recursos, los estilos de vida se fragilizan al afectar las dimensiones alimentación, actividad y ejercicio, control del estrés, relaciones interpersonales, entre otras.

Introduction: the severe acute respiratory syndrome Sars-CoV-2 pandemic, caused by a coronavirus called COVID-19, has significantly revolutionized the lifestyles of the university population, it requires knowledge and good practices to avoid contagion through self-care; the challenges and adaptations of learning in a virtual environment lead to modified lifestyles, related to an increase in sedentary lifestyle, stress and fear of contagion, among others. Objective: determine healthy lifestyles, knowledge and care practices due to the Covid-19 pandemic in nursing students at the University of Morelos. Material and methods: descriptive, cross-sectional study, with participation of 265 students. The HPLP-II online questionnaires were applied, asses lifestyles and an exprofessional questionnaire for knowledge, and practice of care during the pandemic, were applied during September to October 2020. Results: knowledge: students only recognize respiratory symptoms; they mention that they practice only some of safety measures, associations were obtained between knowledge, practice and lifestyles, p = <. 05. Discussion: studies in Peru, Colombia, Spain and Mexico reveal similar and significant results; these relate quality of life and lifestyles, knowledge, attitudes and appropriate practices, as well as positive attitudes of university students towards COVID-19. Conclusion: the university population is vulnerable to contagion, it has not yet dimensioned the magnitude of the problem that it is experiencing, it has few resources, and lifestyles are weakened by affecting the dimensions of nutrition, activity and exercise, stress control, interpersonal relationships, among others.

Compliance with the clinical guidelines for managing asthma by primary care physicians: An ambispective observational study.

OBJECTIVE: To assess the degree of compliance with the recommendations of the 2009 and 2015 versions of the Spanish guidelines for managing asthma (Guía Española para el Manejo del Asma [GEMA]) and the effect of this compliance on controlling the disease. MATERIAL AND METHODS: We conducted an observational ambispective study between September 2015 and April 2016 in which 314 primary care physicians and 2864 patients participated. RESULTS: Using retrospective data, we found that 81 of the 314 physicians (25.8%; 95% CI 21.3-30.9) stated that they complied with the GEMA2009 recommendations. At the start of the study, 88 of the 314 physicians (28.0%; 95% CI 23.4-33.2) complied with the GEMA2015 recommendations. Poorly controlled asthma (OR, 0.19; 95% CI 0.13-0.28) and persistent severe asthma at the start of the study (OR, 0.20; 95% CI 0.12-0.34) were negatively associated with having well-controlled asthma by the end of the follow-up. In contrast, compliance with the GEMA2015 recommendations was positively associated with a greater likelihood that the patient would have well-controlled asthma by the end of the follow-up (OR, 1.70; 95% CI 1.40-2.06). CONCLUSIONS: Low compliance with the clinical guidelines for managing asthma is a common problem among primary care physicians. Compliance with these guidelines is associated with a better asthma control. Actions need to be taken to improve primary care physician compliance with the asthma management guidelines.

Objetivo Evaluar el grado de seguimiento de las recomendaciones de las versiones de la Guía española para el manejo del asma (GEMA 2009 y 2015) y su repercusión en el control de la enfermedad. Material y métodos Estudio observacional y ambispectivo realizado entre septiembre del 2015 y abril del 2016, en el que participaron 314 médicos de atención primaria y 2.864 pacientes. Resultados Utilizando datos retrospectivos, 81 de los 314 médicos (25,8% [IC del 95%, 21,3 a 30,9]) comunicaron seguir las recomendaciones de la GEMA 2009. Al inicio del estudio, 88 de los 314 médicos (28,0% [IC del 95%, 23,4 a 33,2]) seguían las recomendaciones de la GEMA 2015. El tener un asma mal controlada (OR 0,19, IC del 95%, 0,13 a 0,28) y presentar un asma persistente grave al inicio del estudio (OR 0,20, IC del 95%, 0,12 a 0,34) se asociaron negativamente con tener un asma bien controlada al final del seguimiento. Por el contrario, el seguimiento de las recomendaciones de la GEMA 2015 se asoció de manera positiva con una mayor posibilidad de que el paciente tuviera un asma bien controlada al final del periodo de seguimiento (OR 1,70, IC del 95%, 1,40 a 2,06). Conclusiones El escaso seguimiento de las guías clínicas para el manejo del asma constituye un problema común entre los médicos de atención primaria. Un seguimiento de estas guías se asocia con un control mejor del asma. Existe la necesidad de actuaciones que puedan mejorar el seguimiento por parte de los médicos de atención primaria de las guías para el manejo del asma (AU)

Aplicación del modelo de Educación Deportiva en segundo de Educación Primaria. Percepciones del alumnado y el profesorado / Sport Education model in second grade. Teachers and students’ perceptions / A aplicação do Modelo de Educação Desportiva no Segundo ano do primeiro ciclo de ensino. Perceções de alunos e professores

El presente trabajo pretende analizar la viabilidad del modelo de Educación Deportiva en segundo de Educación Primaria (7-8 años), a partir del análisis de las percepciones de una alumna en prácticas, su maestra colaboradora y los alumnos participantes, en el desarrollo de una unidad didáctica de balón prisionero. Se analizaron las percepciones de los docentesa través de entrevistas, y las de los alumnos mediante un cuestionario (Physical Education Season Survey; Mohr, Townsend, Rairigh y Mohr, 2003;Hastie y Sinelnikov, 2006) y la realización de dibujos. Los resultados mostraron percepciones muy positivas por parte de docentes y alumnos. Los resultados, en cuanto a dificultades y beneficios percibidos, coinciden conlo mostrado en la literatura tanto nacional como internacional en la percepción del modelo por parte de docentes y alumnos de mayor edad, lo cual parece indicar que el modelo de Educación Deportiva puede implementarse con éxito con alumnos de 7 años (AU)

This work analyzes the appropriateness of implementing Sport Education with second graders, through the experience of a pre-service teacher, the collaborator teacher, and students' perceptions during a teaching unit of Dodgeball conducted following the features of Sport Education. Pre-service teacher's and collaborator teacher's perceptions were analyzed through interviews. Students' perceptions were analyzed through the "Physical Education Season Survey" (Mohr, Townsend, Rairigh y Mohr, 2003; Hastie y Sinelnikov, 2006) and through drawings. Results are consistent with Spanish and international literature conducted with older students, thus, it can be conclude that Sport Education model can be appropriate for students as young as seven years old

Este trabalho analisa a viabilidade de implementar o Modelo de Educação Desportiva no Segundo ano do primeiro ciclo de ensino (7-8 anos), a partir da análise das perceções de um estudante-estagiário, do professor cooperante e dos alunos participantes numa unidade de ensino de dodgeball. As perceções dos professores foram captadas através de entrevistas e as dos alunos por meio de um questionário e da análise de desenhos (Physical Education Season Survey; Mohr, Townsend, Rairigh, y Mohr, 2003; Hastie y Sinelnikov, 2006). Os resultados mostraram que professores e alunos percecionaram ter vivido uma experiência extremamente positiva. A natureza dos benefícios percebidos e dos constrangimentos encontrados estão em concordância com achados anteriores, tanto da literatura espanhola como na internacional, sobre as perceções que professores e alunos mais velhos sustêm sobre o modelo. É fortemente sugerido que o Modelo de Educação Desportiva tem potencial para ser implementado com sucesso também com alunos na faixa etária dos 7 anos

Self-reported and measured cardiorespiratory fitness similarly predict cardiovascular disease risk in young adults.

We aimed to (a) examine the validity and reliability of the International FItness Scale (IFIS) in Spanish young adults and (b) compare the capacity of self-reported vs measured fitness to predict cardiovascular disease (CVD) risk. The study comprised 276 participants (18-30 years). Fitness level (overall and specific components) was both self-reported (IFIS) and measured using standard fitness tests. Total and trunk fat was assessed by dual-energy X-ray absorptiometry. We computed a previously validated metabolic syndrome score. A separate sample of 181 of same age and characteristics fulfilled IFIS twice for reliability purposes. The results of the present study support the validity and reliability of self-reported fitness, as measured by IFIS, in Spanish young adults. Our data also suggest that not only measured cardiorespiratory fitness but also self-reported cardiorespiratory fitness predicts CVD risk, as assessed by adiposity and metabolic syndrome indicators. The associations for muscular fitness (both reported and measured) differed depending on how it was expressed (i.e., absolute vs relative terms). Self-reported fitness, as assessed by IFIS, can be a good alternative when physical fitness cannot be measured in large surveys.

Influence of brine concentration on swelling pressure of pork meat throughout salting.

The influence of sodium chloride on the water holding capacity of meat is well known and described in literature. An increase in water holding capacity is associated with an increase in the swelling pressure in the protein matrix. A novel device was used to measure the swelling pressure during brine salting of muscle cylinders (40×50 mm), in different NaCl brine concentrations (2.5 to 25%) over 6 days at 4°C. Changes in meat composition, weight and height of non-constrained control samples were also measured. The aim of this work was to prove the feasibility of using the developed device in order to quantify the influence of the brine concentration on the magnitude of the swelling pressure. The obtained results indicated the adequacy of the developed device for measuring the meat swelling, while a good correlation of the swelling pressure and the changes in weight and height of the samples was observed.

Colour, turbidity and COD removal from old landfill leachate by coagulation-flocculation treatment.

The application of different coagulants and flocculants to leachate from an old landfill to determine the optimum conditions for removal of organic matter, colour and turbidity is studied. Ferric chloride, aluminium sulphate, aluminium polychloride (PAX) and polyacrylamide polyelectrolytes were tested. Higher pollutant removals (73% COD, 98% colour and 100% turbidity) were obtained using ferric chloride at pH 5.0-5.5 and for a dosage of 0.6 g Fe l(- 1). The volume of sludge generated after centrifugation represents about 4.0-4.6% when ferric chloride or aluminium sulphate is used, and 10% when employing aluminium polychloride. When flocculants were also added, the results obtained were similar to those found when adding only coagulants, although a considerable increase in the settling rate was obtained.

Coagulation-flocculation as a pretreatment process at a landfill leachate nitrification-denitrification plant.

The main aim of this research work was to study the possible application of coagulation-flocculation as a pretreatment process for young landfill leachate in order to prevent fouling in the ultrafiltration membranes employed for the separation of biomass in the biological plant. Jar-test experiments were carried out to determine the optimum conditions for the removal of turbidity colour and organic matter. The coagulants ferric chloride, aluminium sulphate and aluminium polychloride (PAX) were tested, along with different types of flocculants (anionic and cationic polyelectrolytes). Optimum pH values were around 4.0 and 6.0 for ferric chloride and aluminium sulphate, respectively. It was not necessary to alter the pH of the leachate when using PAX, as the optimum value was found to be similar to that of the leachate (around 8.3). Optimum dosages were 0.4 g Fe(3+)/L, 0.8 g Al(3+)/L and 4 g PAX/L, although there was not much difference in the results for lower dosage of PAX. The best results were found with this coagulant, obtaining 98% turbidity removal, 91% colour removal and 26% COD removal. When flocculants were also added, the results were similar to those found when adding only coagulants, although a considerable increase in the settling rate was obtained. The volume of the sludge generated represents around 4.5-5.0% when using ferric chloride or aluminium sulphate, and 15% when using aluminium polychloride.

[Long-term results of end-to-end urethroplasty]. / Resultado a largo plazo de la uretroplastia término-terminal.

OBJECTIVE: We evaluated long term results of end-to-end urethroplasty. MATERIAL AND METHODS: We reviewed 40 patients with bulbar urethral stricture of diverse origin: iatrogenic 40%, traumatic 15%, infectious 2% and unknown 40%. In 17 cases internal urethrotomy was made previously. The radiological study with retrograde and voiding cystogram revealed a bulbar location in all cases and a length inferior to 1 cm in 13 cases, between 1-2 cm in 26 cases and 2-3 cm in 1 case. The maximum flow rate varied between 3-13 ml/s. The absence of bacteriuria was valued by means of preoperating culture. The average time of pursuit was 45 months (12-142 months). The stricture was considered resolute when not appear compatible radiological or functional finds of failure. RESULTS: In 37 cases (92%) the results were satisfactory, without secondary surgical procedure. After surgery maximum flow-rate varied between 18-45 ml/s. In two patients with failure, internal urethrotomy was decisive. In this case the stricture origin was traumatic. The third patient with failure was finally chosen to make new end-to-end urethroplasty, with good later result. CONCLUSIONS: End-to-end urethroplasty is a highly decisive technique for bulbar urethral stricture. The preoperating diagnosis is based on the radiological study (retrograde and voiding cystogram). The postoperating control must be based on clinic and uroflow study. Traumatic stricture repair showed worse results. In cases of failure, internal urethrotomy allows to complement successful results of end-to-end urethroplasty.

Resultado a largo plazo de la uretroplastia término-terminal / Long-term results of end-to-end urethroplasty

Objetivo: Evaluamos los resultados a largo plazo de la uretroplastia término-terminal. Material y Métodos: Revisamos 40 pacientes afectos de estenosis de uretra bulbar de etiología diversa: yatrógena40%, traumática 15%, infecciosa 2% y desconocida 40%. En 17 casos se realizó previamente uretrotomíainterna. El estudio mediante CUMS reveló una localización bulbar en todos los casos y una longitud inferior a 1cm en 13 casos, entre 1-2 cm en 26 casos y entre 2-3 cm en 1 caso. El flujo máximo varió de 3-13 ml/s. Se valoró mediante cultivo preoperatorio la ausencia de bacteriuria. El tiempo medio de seguimiento fue de 45 meses (12-142 meses). Se consideró resuelta la estenosis cuando no aparecieron datos radiológicos ni flujométricos compatibles con reestenosis. Resultados: En 37 casos (92%) los resultados fueron satisfactorios, no precisando los pacientes ningún otro procedimiento quirúrgico secundario. Tras la cirugía el flujo máximo varió entre 18-45 ml/s. En dos de los tres pacientes con reestenosis la uretrotomía interna endoscópica fue resolutiva. Se trató de dos pacientes con estenosisde origen traumático y longitud mayor a 1,5 cm. En el tercer paciente con recidiva se optó finalmente por realizar una nueva uretroplastia termino-terminal, con buen resultado posterior. Conclusiones: La uretroplastia término-terminal es una técnica altamente resolutiva en la estenosis de uretrabulbar. El diagnóstico preoperatorio se basa en el estudio radiológico (CUMS). El control postoperatorio debe fundamentarse en la clínica y estudio flujométrico. El origen traumático de la estenosis empeora los resultados de la cirugía. En casos de reestenosis la uretrotomía interna endoscópica permite complementar de forma exitosa los resultados de la uretroplastia (AU)

[Urologic findings in pseudoxanthoma elasticum: report one case]. / Manifestaciones urológicas del pseudoxantoma elástico: a propósito de un caso.

CASE REPORT: A 21-year-old woman presented with retinal angioid streaks and yellowish streak skin abnormalities in neck and axillary folds. Skin biopsy showed bluish-gray tangled masses of calcified elastic fibers in the mid- to lower dermis suggestive of Pseudoxanthoma elasticum (PXE). She consulted in Urology Department for lower urinary tract infection. Renal ultrasonography revealed multiple highly reflective foci in the corticomedullary junction. COMMENT: Pseudoxanthoma elasticum is a rare genetic disorder characterised by fragmentation and calcification of elastic fibers in the skin and media of arteries. Frequent manifestations include hypertension, angina pectoris, transient cerebral ischemic attacks, intermittent claudication, upper gastrointestinal bleeding, retinal angioid streaks and thickened skin. A characteristic appearance of highly reflective foci in the renal parenchyma have been reported in patients with PXE, but it's not specific for this syndrome. However, the presence of this structural pattern in a young patient with dermatological abnormalities should lead to the consideration of PXE in the differential diagnosis list. Besides ultrasonography findings, only a ureteral disruption case in a patient underwent ureteroscopic manipulation has been described to our knowledge. In our case, the true significance of these disease in recurrent urinary tract infection is uncertain.

Manifestaciones urológicas del pseudoxantoma elástico: a propósito de un caso / Urologic findings in pseudoxanthoma elasticum: report one case

Caso clínico: Mujer de 21 años con estrías angioides retinianas y estrías cutáneas en axilas y cuello. Tras biopsia cutánea con calcificaciones en las fibras elásticas de dermis, fue diagnosticada de Pseudoxantoma elástico. Remitida al Servicio de Urología por infección del tracto urinario inferior, en estudio ecográfico renal presentó múltiples focos hiperecogénicos de pequeño tamaño en la unión córtico-medular. Comentarios: El Pseudoxantoma elástico es una rara enfermedad genética que se caracteriza por la fragmentación y calcificación de las fibras elásticas de la piel y arterias. Las manifestaciones clínicas incluyen hipertensión, angor pectoris, ictus, claudicación intermitente, hemorragia digestiva alta, estrías angioides retinianas y estrías cutáneas. La ecografía se caracteriza por la presencia de múltiples focos hiperecogénicos a nivel del parénquima renal, pero este hallazgo no es específico del Pseudoxantoma elástico. Sin embargo, la presencia de este patrón ultrasonográfico en pacientes jóvenes con anomalías dermatológicas debe hacernos pensar en este síndrome dentro de las diferentes posibilidades diagnósticas. Aparte de los hallazgos ecográficos descritos, sólo una lesión ureteral en una paciente sometida a ureteroscopia ha sido descrita en relación al ámbito urológico de este síndrome. En nuestro caso, la relación entre esta enfermedad y la presencia de infección urinaria recurrente no esta clara

[An evaluation of the feasibility and validity of a scale of social assessment of the elderly]. / Evaluación de la fiabilidad y validez de una escala de valoración social en el anciano.

OBJECTIVES: To analyse the reliability and validity of a scale of social evaluation of the elderly. DESIGN: Descriptive, cross-sectional study. SETTING: Primary care. PATIENTS: Sample of 1062 people from the over-65 population. INTERVENTIONS: The scale evaluated has five items (family situation, economic situation, housing, relationships and social support), and an overall score is obtained. Its reliability was evaluated by an interview with two observers, and validity by contrasting the score obtained on the scale with a reference criterion of an independent, blind assessment by a social work expert. MEASUREMENTS AND MAIN RESULTS: The intraclass correlation coefficient (inter-observer reliability) was 0.957. The Cronbach alpha coefficient was 0.4467, which denoted moderate to low internal consistency. Sensitivity and specificity were calculated for the validity of the criterion. Nevertheless, to detect social problems in care practice, probability proportions for different levels on the scale were more useful. These ranged from 1 to 23, while in the detection of social risk they ranged from 1 to infinity. CONCLUSIONS: The scale studied by us as a measuring instrument enables risk situations and social problems to be detected with good reliability and acceptable validity. It should be introduced into the care practice of professionals working in the social or health care of the elderly.

[Abscess in the posterior third of the tongue. A clinical case]. / Absceso de tercio posterior de lengua. Caso clínico.

A case of lingual abscess visualized by computed tomography is reported. The review of the literature demonstrated the difficulty of diagnosing these cases. Protection and surveillance of the upper airways is important. Computed tomography is the key to diagnosis.
