Difusión de la hipnosis en prensa online escrita en español / Dissemination of hypnosis in the online press written in Spanish

Las creencias y expectativas sobre hipnosis de pacientes/clientes y de profesionales cualificados influyen en la decisión de usar este procedimiento, así́ como en sus efectos. Por otro lado, en Internet hay mucha información sobre hipnosis, que configura la opinión del público y de los profesionales. Por ello, el objetivo de este estudio es analizar la calidad de la información difundida por la prensa online no especializada. Se han analizado 334 (de 2011 a 2012) y 200 artículos (de 2018 a 2019) publicados en español en prensa online no especializada. Los resultados muestran que, aunque un elevado número de artículos desmitifica la hipnosis, muchos de ellos difunden mitos al mismo tiempo. El mayor porcentaje de artículos que desmitifican la hipnosis está asociado al tema “Ciencia y Cultura”. Los resultados indican que los mitos están ampliamente presentes en la cultura popular y se mantienen con el apoyo de su continua difusión en los artículos de prensa online. Esto reafirma la importancia de fomentar la difusión de evidencia científica disponible sobre la investigación aplicada y básica sobre hipnosis. (AU)

The patients/clients and the skilled professionals’ beliefs and expectations about hypnosis, influence the decision to use this procedure as well as its effects. On the other hand, in the Internet there is plenty of information about hypnosis, which shapes opinions of public and professionals. Therefore, the aim of this study is to analyze the quality of the information disseminated by non-specialized online press. 334 articles (from 2011 to 2012) and 200 articles (from 2018-2019) written in Spanish and published online in non-specialized publications press have been analyzed. Results show that, although a high number of articles demystify hypnosis, many of them disseminate myths as well. The highest percentage ofarticles that demystify hypnosis is associated with the press topic “Science and Culture”. Results indicate that myths are broadly present in the popular culture and are maintained with the support of their ongoing dissemination in the newspapers online articles. This supports the importance of fostering the dissemination of scientific available evidence about applied and basic research on hypnosis. (AU)

Conscious Exploration of Alpha-Cuts in the Parametric Solution of the School Bus Routing Problem with Fuzzy Walking Distance.

Combinatorial optimization problems allow for modeling multiple situations in which proper allocation of resources is needed. For some real-world problems, the use of fuzzy elements in the models allows for incorporating certain levels of uncertainty to better approximate such real-world situations. One way to solve combinatorial optimization problems with fuzzy elements is the parametric approach, where it is necessary to define how to explore different relaxation levels using alpha-cuts. Researchers tend to select such alpha-cuts uniformly. The current investigation proposes a novel strategy for selecting alpha-cuts in the School Bus Routing Problem with fuzzy students' maximum walking distance. This proposal bases its foundations on the number of student-bus stop pairs available according to the different levels of relaxations allowed. Results demonstrate how the proposed strategy gives attractive solutions with more diverse trade-offs, contrasted with other methods in the literature. Furthermore, it decreases the computational cost for those instances where the maximum relaxation does not provide new pairs of students-bus stops.

Nevo lipomatoso cutáneo superficial / Superficial cutaneous lipomatous nevus

RESUMEN El nevo lipomatoso cutáneo superficial es un nevo o hamartoma del tejido conectivo, idiopático, caracterizado por tumoraciones lobuladas del color de la piel, únicas o múltiples, con cierta predilección por la cintura pélvica; su aparición es poco frecuente. Histológicamente se destaca la presencia de células grasas maduras localizadas ectópicamente en la dermis. Se presentó un paciente de 40 años de edad con lesión en la piel de la región glútea derecha desde niño. Al examen dermatológico presentaba lesiones papulonodulares múltiples, de color de la piel, de tamaño variable, de consistencia blanda, localizadas en la nalga derecha. Se le realizó exéresis y biopsia de piel de lesión papulonodular de mayor tamaño, con diagnóstico histopatológico de nevo lipomatoso cutáneo superficial.

ABSTRACT A superficial cutaneous lipomatous nevus is an idiopathic connective tissue nevus or hamartoma characterized by single or multiple lobulated skin-colored tumors with a certain predilection for the pelvic girdle; its appearance is rare. Histologically, the presence of mature fat cells located ectopically in the dermis stands out. We present a 40-year-old male patient with a skin lesion of the right gluteal region since he was a child. On dermatological examination, he had multiple, skin-colored, papulonodular lesions of variable size and soft consistency located on the right buttock. Exeresis and skin biopsy of a larger papulonodular lesion were performed, with histopathological diagnosis of superficial cutaneous lipomatous nevus.

El tratamiento de la cervicalgia con la terapia Su-Jok / Su-Jok therapy for cervicalgia treatment

Introducción: alrededor del 10% de la población adulta sufre, en algún momento de su vida, de cervicalgia. La columna cervical mantiene el equilibrio de la cabeza, lo que explica el aumento de la incidencia de cervicalgias, como consecuencia de posturas incorrectas, obligadas y mantenidas por un largo tiempo. Objetivo: determinar, según variables sociodemográficas y biomédicas, la eficacia de la terapia Su-Jok en el tratamiento de la cervicalgia. Métodos: se realizó un estudio cuasi experimental en la Sala de Rehabilitación del Policlínico Mario Gutiérrez Ardaya, del municipio de Holguín, en el período septiembre de 2015 a febrero de 2016. Remitidos por diferentes consultorios médicos, la muestra estuvo constituida por 30 pacientes. Se les aplicó la terapia Su-Jok, con el objetivo de eliminar los síntomas y las sensaciones dolorosas. Resultados: el sexo femenino resultó el más afectado con un 66,67% y los pacientes de 30 a 39 años alcanzaron un 50%. La actividad laboral que más pacientes afectó fue la de los cuentapropistas, con el 40%. Antes de la intervención, en el 63,33% predominaba el dolor severo. Luego de esta, el 76,67% presentó dolor ligero. El 53,33% de los pacientes mejoraron de la 5ta a la 8va sesión. Conclusiones: para la cervicalgia, la terapia Su-Jok es efectiva. En el futuro se requieren ensayos clínicos aleatorios controlados, que validen definitivamente la terapia utilizada.

Introduction: nearly 10% of adult population has a cervicalgia episode. Cervical spine keeps head balance; without it, muscular structure is forced to work harder. Cervicalgias raise is the result of long hours forced body positions. Objective: determining the effectiveness of Su-Jok therapy on cervicalgia treatment, according to biomedical and demographical variables. Methods: a quasi-experimental survey was carried out at the rehabilitation ward of "Mario Gutierrez Ardaya" clinic, at Holguín municipality, from September 2015 to February 2016. Sample was composed by 30 patients, referred to our center by their family doctors. Therapy was applied and the technique used was Su-Jok, to diminish symptoms and pain. Results: patients were 30-39 years old with 50%. Female were the most affected up to 66.67%. Self-employed patients were the most affected with 40%. Before the intervention, severe pain lead numbers with 63.33% and later, 76.67% showed light pain. The 53.33% of patients showed positive reactions from the 5th till 8th sessions. Conclusions: Su-Jok therapy is effective in cervicalgia. Controlled clinical trials are required therapy validation and usage.

Comparison of two repositioning schedules for the prevention of pressure ulcers in patients on mechanical ventilation with alternating pressure air mattresses.

PURPOSE: The objective was to compare the effectiveness of repositioning every 2 or 4 h for preventing pressure ulcer development in patients in intensive care unit under mechanical ventilation (MV). METHODS: This was a pragmatic, open-label randomized clinical trial in consecutive patients on an alternating pressure air mattress (APAM) requiring invasive MV for at least 24 h in a university hospital in Spain. Eligible participants were randomly assigned to groups for repositioning every 2 (n = 165) or 4 (n = 164) h. The primary outcome was the incidence of a pressure ulcer of at least grade II during ICU stay. RESULTS: A pressure ulcer of at least grade II developed in 10.3% (17/165) of patients turned every 2 h versus 13.4% (22/164) of those turned every 4 h (hazard ratio [HR] 0.89, 95% confidence interval [CI] 0.46-1.71, P = 0.73). The composite end point of device-related adverse events was recorded in 47.9 versus 36.6% (HR 1.50, CI 95% 1.06-2.11, P = 0.02), unplanned extubation in 11.5 versus 6.7% (HR 1.77, 95% CI 0.84-3.75, P = 0. 13), and endotracheal tube obstruction in 36.4 versus 30.5%, respectively (HR 1.44, 95% CI 0.98-2.12, P = 0.065). The median (interquartile range) daily nursing workload for manual repositioning was 21 (14-27) versus 11 min/patient (8-15) (P < 0.001). CONCLUSIONS: A strategy aimed at increasing repositioning frequency (2 versus 4 h) in patients under MV and on an APAM did not reduce the incidence of pressure ulcers. However, it did increase device-related adverse events and daily nursing workload.

Hospital-acquired pressure ulcers and risk of hospital mortality in intensive care patients on mechanical ventilation.

RATIONALE, AIMS AND OBJECTIVES: Pressure ulcers (PUs) are a common and serious complication in critically ill patients. The aim of this study was to evaluate the relationship between the development of a PU and hospital mortality in patients requiring mechanical ventilation (MV) in an intensive care unit (ICU). METHODS: A prospective cohort study was performed over two years in patients requiring MV for ≥ 24 hours in a medical-surgical ICU. Primary outcome measure was hospital mortality and main independent variable was the development of a PU grade ≥ II. Hazard ratios (HRs) were calculated using a Cox model with time-dependent covariates. RESULTS: Out of 563 patients in the study, 110 (19.5%) developed a PU. Overall hospital mortality was 48.7%. In the adjusted multivariate model, PU onset was a significant independent predictor of mortality (adjusted HR, 1.28; 95% confidence interval, 1.003-1.65; P = 0.047). The model also included the Acute Physiology and Chronic Health Evaluation II score, total Sequential Organ Failure Assessment on day 3, hepatic cirrhosis and medical admission. CONCLUSION: Within the limitations of a single-centre approach, PU development appears to be associated with an increase in mortality among patients requiring MV for 24 hours or longer.

Allogrooming behavior inCercocebus torquatus: The case for the hygienic functional hypothesis.

The hygienic functional hypothesis of allogrooming behavior was examined in two captive groups (N=9 andN=8) of white-crowned mangabeys (Cercocebus torquatus lunulatus) by analyzing: (1) the corporal distribution of manipulation type according to hair density, and (2) the corporal distribution of allogrooming according to presence of wounds. In both groups the sites with higher hair density received more bouts of Superficial Grooming, which implies a tactile screening of a fragment of the body surface. Only one group tended to emit more allogrooming on the body sites when they were wounded. In the other group, however, the number of wounds was very small and the wounds concentrated predominantly on those sites which were accessible to the subject itself. Thus, our results may be consistent with the hygienic functional hypothesis of allogrooming behavior in general and with the sanitary one in particular.
