Psoriasis is a high incidence dermatosis related to stress, and its sufferers provide an appropriate target group to carry out interventions such as those based on mindfulness, aimed at helping emotion regulation. To assess the Compassionate Emotional Accompaniment Technique (CEAT) effects within a brief mindfulness-based intervention on emotional coping in patients with severe psoriasis to determine the efficacy of emotional coping after the induction of a negative emotional state. Forty-four adults (59.1% were women) aged 22-71 years (M = 51.95, SD = 11.87) with severe psoriasis were assigned randomly to the CEAT group or the Emotional Disclosure control group. Subjective discomfort, cognitive ability, affect, and heart rate were assessed before and after the interventions, with two follow-ups at 48 hours and seven days. The results show significant statistical differences in favor of the CEAT intervention versus the Emotional Disclosure group, being more effective in the emotional management after induction and follow-up. These results encourage interventions in a clinical setting with patients with severe psoriasis, so future research should consider using this intervention type to improve emotional management with this population group.
La psoriasis es una dermatosis de alta incidencia relacionada con el estrés, constituyendo las personas que lo padecen, un grupo objetivo adecuado para llevar a cabo intervenciones basadas en mindfulness, destinadas a ayudar a la regulación de las emociones. El objetivo del presente estudio es evaluar los efectos de la Técnica de Acompañamiento Emocional Compasivo (CEAT), como una intervención breve basada en mindfulness, sobre el afrontamiento emocional en pacientes con psoriasis grave, para determinar la eficacia del afrontamiento emocional tras la inducción de un estado emocional negativo. Cuarenta y cuatro adultos (el 59,1% mujeres) con edades comprendidas entre los 22 y los 71 años (M = 51,95, DT = 11,87), con psoriasis grave, fueron asignados aleatoriamente a un grupo de intervención con CEAT o a un grupo control de intervención de Revelación Emocional. Se evaluaron malestar subjetivo, capacidad cognitiva, afecto y frecuencia cardíaca, antes y después de las intervenciones, con dos seguimientos a las 48 horas y a los siete días. Los resultados muestran diferencias estadísticas significativas a favor de la intervención CEAT frente al grupo de Revelación Emocional, siendo más eficaz en el manejo emocional tras la inducción y el seguimiento. Estos resultados podrían favorecer la intervención en entornos clínicos con pacientes con psoriasis grave, y futuras investigaciones podrían considerar el uso de esta para mejorar la gestión emocional en este tipo de población

The relationship between online-offline socialization contexts during adolescence has become a relevant research topic in recent years, especially in the field of intimate partner violence. To better understand this association, the present study analyzes the relationship between dating violence (DV) victimization and the problematic social networking sites use (PSNSU), the feeling of loneliness, and the family climate, taking into account the adolescents' gender. 1020 adolescents from Andalusia participated (49% boys, M = 16.12, SD = .99). A cluster analysis, which established two groups (victimized and non-victimized), multivariate analysis of variance (2x2 MANOVA) using sex and DV as independent variables, and univariate analysis of variance to explore the significant relationships detected, were performed. The results showed that adolescent victims of DV obtained higher scores than non-victims in PSNSU, feelings of loneliness, and family conflict, and lower scores in family cohesion. Victimized girls generally showed lower scores than victimized boys. The results obtained provide relevant and useful information for the prevention of DV and the promotion of healthy relationships in early dating relationships. In addition, they point out the importance of considering the online context in research on violence in adolescence.
La relación existente entre los contextos de socialización online-offline durante la adolescencia se ha convertido en un tema de investigación relevante en los últimos años, especialmente en el ámbito de la violencia de pareja. Para entender mejor este vínculo, el presente estudio analiza la relación entre la victmización en la violencia de pareja, el uso problemático de las redes sociales virtuales, el sentimiento de soledad y el clima familiar, considerando el género de los adolescentes. Participaron 1020 adolescentes procedentes de Andalucía (49% chicos, M = 16.12; DT = .99). Se realizó un análisis por conglomerados que permitió establecer dos grupos (victimizados y no victimizados), un análisis multivariado de la varianza (2x2 MANOVA) utilizando sexo y violencia de pareja como variables independientes y análisis univariados de varianza para explorer las relaciones significativas detectadas. En los resultados se observó que los/las adolescentes víctimas de violencia de pareja obtuvieron puntuaciones más elevadas que las no víctimas en la adicción a las redes sociales virtuales, sentimiento de soledad y conflicto familiar, y puntuaciones más bajas en cohesión familiar. Las chicas victimizadas mostraron en general puntuaciones más bajas que los chicos victimizados. Los resultados obtenidos aportan información relevante y útil para la prevención de la violencia de pareja y el fomento de relaciones saludables en las primeras relaciones amorosas. Además, señalan la importancia de considerar el contexto online en la investigación acerca de la violencia en la adolescencia.

Background: Resilience in teachers allows them to face difficult situations to recover from adversity and there are gender differences. Likewise, artificial intelligence and the techniques associated with it have proven to be very useful in predicting educational variables and studying the interconnection between them after COVID-19. That said, the general objective of this research was to predict the levels of resilience in secondary school teachers through the design of an artificial neural network (ANN). Method: The Brief Resilient Coping Scale, the Maslach Burnout Inventory and the COVID-19 Stress Questionnaire were administered to 401 secondary school teachers (70.6% female) from schools in southeastern Spain, with a mean age of 44.36 years (SD = 9.38). Results: Differences were found in the configuration of the predictive models of resilience between male and female teachers, with the independent variables contributing to different degrees depending on gender. Conclusions: It is highlighted the usefulness of ANNs in the educational setting and the need to design more adjusted programs.
Antecedentes: La resiliencia en el profesorado permite afrontar situaciones difíciles y reponerse a la adversidad existiendo diferencias de género al respecto. Asimismo, la inteligencia artificial y las técnicas asociadas a ella han resultado ser de gran utilidad para predecir variables educativas y estudiar la interconexión entre ellas tras la COVID-19. Dicho esto, el objetivo general de esta investigación fue predecir los niveles de resiliencia en las profesoras y profesores de Secundaria a través del diseño de una red neuronal artificial (RNA). Método: Se administró la Escala Breve de Afrontamiento Resiliente, el Inventario de Burnout de Maslach y el Cuestionario de Estrés frente a la COVID-19 a 401 docentes de secundaria (70.6% mujeres) de centros educativos del sureste español, con una edad media de 44.36 años (DT= 9.38). Resultados: Se hallaron diferencias en la configuración de los modelos predictivos de la resiliencia entre profesoras y profesores contribuyendo las variables independientes en diferente grado en función del género. Conclusiones: Se pone de manifiesto la utilidad de las RNA en el ámbito educativo y la necesidad de diseñar programas más ajustados.

AbstractObjectives: To evaluate the efficacy of vaginal misoprostol for cervical ripening and labor induction in premature rupture of membranes (PROM) cases with low Bishop scores at term. Methods: Sixty‐two PROM cases who fulfilled the criteria of 36 weeks of completed gestation, not in active labor, singleton pregnancy with vertex presentation, normal fetal heart rate reactivity, amniotic fluid index >5 cm and Bishop score <5, consented to participate in the study. Thirty‐one of the cases were included in study group and a 50‐μg misoprostol tablet was placed in the posterior vaginal fornix. Another 31 cases were included in control group and managed expectantly. Treatment success was defined as an interval from membrane rupture to delivery of <24 h. Results: The mean admittance–delivery interval was significantly shorter in the study group (8.68±4.40 h) compared with the control group (26.22±18.98 h, P=0.001) and the mean interval from membrane rupture to delivery were also significantly shorter in the study group (19.37±7.20 h) than the control group (33.05±20.85 h, P=0.001). Oxytocin necessity was significantly lower in the study group than the control group (45.2% vs. 100%, P=0.00051). Tachysystole occurred more frequently in the study group (8 cases, 25.8% vs. 2 cases, 6.5%, P=0.038). There were no difference between two groups with regard to birth weights, 1‐ and 5‐min Apgar scores and the need for neonatal intensive care unit. Conclusions: It is effective, safe and economic to use misoprostol vaginally in PROM cases with low Bishop scores at term.

Published: July 2002

AbstractThe main interest of this work was the investigation of the transport mechanisms of salmon calcitonin through the epithelial cell monolayer in the presence and absence of pH‐sensititive hydrogel nanospheres composed of poly(methacrylic acid‐grafted‐poly(ethylene glycol)) (PMAA‐g‐EG). For this purpose, a gastrointestinal cell culture model, the Caco‐2 cell line, was employed. The transport of other macromolecules such as fluorescein sodium, fluorescein isothiocyanate dextran, and 14C‐mannitol were also investigated and compared. Transport experiments were conducted in the apical‐to‐basolateral direction at 37 and 5 °C and from the basolateral‐to‐apical direction at 37 °C. Results revealed that the presence of P(MAA‐g‐EG) nanospheres increased the transport of paracellularly transported molecules such as 14C‐mannitol and fluorescein isothiocyanate dextran when compared to controls. Fluorescein sodium salt solutions were investigated as an actively transported molecule. The transport of fluorescein was affected by the concentration of PEG chains in the structure. Salmon calcitonin transport was enhanced in the presence of the nanospheres. The comparison of the transport behavior of dextran and calcitonin revealed that the main transport mechanism for salmon calcitonin through epithelial cell monolayers is predominantly paracellular.
TRANSHIATAL VERSUS IVOR‐LEWIS OESOPHAGECTOMY: IS THERE A DIFFERENCE?
Authors: Rindani Rahul , Martin Christopher J. , Cox Michael R. 
Published: July 2002

Introduction: Curative oesophageal resection for carcinoma may be carried out by either the transhiatal or the Ivor‐Lewis transthoracic technique. The aims of this study were to compare the morbidity, 30‐day mortality and long‐term survival of the two techniques in the treatment of oesophageal carcinoma and to provide data to calculate the sample sizes for a prospective randomized trial. Methods: Results from 44 series published between January 1986 and December 1996 were reviewed. Thirty‐three papers reported results on 2675 patients having transhiatal (THO) and 29 papers reported results on 2808 patients having Ivor‐Lewis oesophagectomy (ILO). Results: The two groups were comparable in terms of age, sex and stage of the disease. There was no apparent difference in postoperative morbidity between the two groups with respect to respiratory complications (24% for THO, 25% for ILO), cardiovascular complications (12.4% for THO, 10.5% for ILO), wound infection (8.8% for THO, 6.2% for ILO) and chylothorax (2.1% for THO, 3.4% for ILO). The transhiatal group appeared to have a higher incidence of anastomotic leaks (16% for THO, 10% for ILO), anastomotic strictures (28% for THO, 16% for ILO) and recurrent laryngeal nerve injuries (11.2% for THO, 4.8% for ILO). The 30‐day mortality was 6.3% for transhiatal and 9.5% for Ivor‐Lewis oesophagectomy. Overall long‐term survival at 5 years was similar (24% for THO, 26% for ILO). Conclusions: The surgical approach to oesophagectomy was not an important determinant of morbidity and long‐term survival in patients with oesophageal carcinoma. Transhiatal oesophagectomy was associated with a higher incidence of anastomotic complications and recurrent laryngeal nerve injury. Ivor‐Lewis oesophagectomy had a higher mortality. In order to demonstrate a significant difference in morbidity or long‐term survival between the two techniques 3100 patients would be required in each arm of a prospective randomized trial.

Published: July 2002

Objectives To review the urological abnormalities in conjoined twins, a rare congenital abnormality arising from an incomplete separation of a pair of monozygotic twins, and who can be joined from the head to the pelvis with varying degrees of union.Patients and methods The records and urological anomalies of conjoined twins presenting from 1985 to 1995 were reviewed retrospectively and the management and surgical reconstruction described.Results Seven of 11 sets of conjoined twins underwent surgical exploration. Complex urological problems occurred in all twins with omphalo‐ischiopagus. The urological anomalies were: Set 1; both twins had one lateral crossed fused renal ectopia with uncrossed ureters draining into a single bladder with one urethra. They had one set of genitalia. Each twin received one crossed fused ectopic kidney, half the bladder and genitalia, with one retaining the urethra and one a vesicostomy. Set 2; these twins had four kidneys (two lateral and two central that were fused), four ureters (two of which crossed) and these drained into two sagittal bladders that emptied by one urethra associated with a single set of external genitalia containing three corpora cavernosa. At separation, the crossed ureters were re‐routed, each received a bladder and the genitalia were split. Set 3; there were four kidneys with two crossed ureters draining into two collateral bladders, there was a partial duplication of the urethra and a single hypospadiac penis. After separation, each had kidneys draining into a bladder, one received the urethra and external genitalia, and one a urostomy.Conclusion Complex urological problems occur in conjoined twins, although restricted to those with pelvic fusion (ischiopagus). Assessment and treatment needs to be individualised and overseen by a surgeon with experience in complex urology.
Fatal emphysematous pyelonephritis with gas in the spinal extradural space in a patient with diabetes
Authors: Sailesh S. , Randeva H. S. , Hillhouse E. W. , Patel V. 
Published: July 2002

SUMMARY Background  Emphysematous pyelonephritis (EP) is a rare but life‐threatening condition of the upper urinary tract, characterized by the presence of gas in the renal parenchyma and perirenal space. The vast majority of patients with EP (90%) are known to have diabetes, with Escherichia coli being the most common causative pathogen.Case report  We present a case of fatal bilateral EP in a patient with diabetes, with an unusual radiological finding of gas around the spinal cord and in the psoas muscle, with renal parenchymal sparing. Our case serves as an important reminder of this life threatening entity in diabetic patients, which is not well recognized by clinicians because of its rarity.
Cervical incompetence: the use of transvaginal sonography to provide an objective diagnosis
Authors: Macdonald R. , Smith P. , Vyas S. 
Published: July 2002

AbstractObjectiveTo investigate the use of transvaginal sonography in monitoring the cervix in women at high risk of a preterm delivery.Study designOne hundred and six women at high risk of preterm labor had regular cervical monitoring by transvaginal ultrasound throughout pregnancy from the second trimester to delivery. The study was designed to be observational, but intervention was considered if the cervical length fell below 10 mm.ResultsEleven women demonstrated opening of the cervical canal at rest or with fundal pressure before 24 weeks' gestation. Between 2 and 17 days later all 11 cervices progressively shortened to a cervical length of < 10 mm. Nine women had a cervical cerclage. Seven women had fetal membranes visible within the cervical canal at the time of cerclage. One woman miscarried at 18 weeks, and the other 10 had live births at a median gestational age of 36 (range, 27–38) weeks.ConclusionsCervical length shortening in the second trimester, once started, progressed to a cervical length under 10 mm. Opening of the cervical os at rest or in response to fundal pressure detected by transvaginal ultrasound appears to be the early ultrasound feature of cervical incompetence.

Authors: Pantoni Leonardo , Sarti Cristina , Pracucci Giovanni , Di Carlo Antonio , Vanni Paola , Inzitari Domenico , For The Italian Longitudinal Study on Aging  
Published: July 2002

OBJECTIVE: To investigate elevated lipoprotein(a) [Lp(a)] levels as a risk factor for stroke, myocardial infarction, angina, intermittent claudication, and combination of the above in a cohort of unselected older individuals.DESIGN: Population cohort from one of the eight centers participating in the Italian Longitudinal Study on Aging (ILSA).SETTING: General community.PARTICIPANTS: A subsample of 446 subjects (M/F: 231/215, mean age: 74.5 ± 5.7 years) of the original, randomly selected, population cohort of 704 individuals, 65 to 84 years of age, free‐living or institutionalized in the Impruneta Municipality, area of Florence, Italy.MEASUREMENTS: Conventional vascular risk factors and vascular diseases defined following a two‐step procedure (screening phase and confirmation on positives) using standard and validated criteria. Lp(a) levels determined by an ELISA method.RESULTS: No association was observed between elevated Lp(a) levels alone and any of the examined vascular diseases (stroke, myocardial infarction, angina, and intermittent claudication). In contrast, examining the interactions between elevated Lp(a) and conventional vascular risk factors, when elevated Lp(a) was combined with a history of smoking, a marked increase in the risk of vascular diseases combined (odds ratio [OR]: 4.12; 95% confidence interval [CI]: 1.27–13.40) was observed, much higher than that expected based on the additive effect of smoking and elevated Lp(a) alone.CONCLUSIONS: With the cautions due to the cross‐sectional design of the study and the limited statistical power, these results suggest a possible synergistic effect between elevated Lp(a) levels and other pro‐atherogenic factors such as smoking on the risk of vascular diseases in older individuals.
Dynamics of the detonation products of lead azide. I. Hydrodynamics
Authors: Tzuk Y. , Bar I. , Ben-Porat T. , Rosenwaks S. 
Published: July 2002

The present paper is the first of a series reporting on a comprehensive study of the hydrodynamics, kinetics, and spectroscopy of the transient species formed following the detonation of lead azide (LA). The spatial and temporal behavior of the detonation products expanding into vacuum is obtained via high-speed framing photography, transmission of a HeNe laser beam, and chemiluminescence from excited Pb atoms. The photography reveals that following the initiation of LA the products form an expanding, bell-shaped cloud. The HeNe beam is attenuated when the cloud of products traverses its route. The attenuation starts 4–15 μs after initiation and depends on the height of the beam above the LA sample. The chemiluminescence consists of two components: the first, appearing 1–2 μs after initiation, is obtained from excited products formed by the detonation near the surface of the sample, while the second, starting 2–14 μs after initiation, originates from the expanding cloud of products.
The intensity and the temporal behavior of the second component of chemiluminescence depend on the distance to a barrier placed above the LA sample. The cloud contains gaseous products and solid particles which propagate perpendicular to the LA surface with a maximum velocity of 4.48±0.10 km/s and 3.78±0.18 km/s, respectively. To reproduce the experimental results, two alternative hydrodynamic models are applied: Stanyukovich’s model [K. P. Stanyukovich, Unsteady Motion of Continuous Media (Pergamon, London, 1960), pp. 498–501] for isentropic expansion and London and Rosen’s model [R. A. London and M. D. Rosen, Phys. Fluids 29, 3813 (1986)] for exploding foil. The latter model is preferred and when incorporating Beer’s law and Mie’s theory [C. F. Bohren and D. R. Huffman, Absorption and Scattering of Light in Small Particles (Wiley, New York, 1983), p. 77] it reproduces very well both the temporal behavior of the second component of chemiluminescence and the attenuation of the HeNe beam and suggests that lead particles with radius of 0.05–0.15 μm are involved in the attenuation. The model also provides an estimate of the composition of the product cloud and of the density of the gaseous and solid species as a function of time and distance from the LA sample.
