ABSTRACT

BACKGROUND: Interest in characterizing individuals involved in addictive behaviors has been growing, which allows tailoring prevention and intervention strategies to the gambler's needs. The study aimed to 1) identify clusters of gamblers according to gambling-related characteristics and mental health; and 2) analyze differences in psychological variables between the clusters. METHODS: A total of 83 participants undergoing treatment for gambling disorder (Mage = 45.52, 51.8 % female) completed a set of questionnaires. Hierarchical cluster analysis was performed to classify gambling based on gambling variables (i.e., gambling severity and gambling motives) and mental health (i.e., depression, anxiety, and hostility). Several ANOVAs were conducted to illustrate the distinguishing features of each cluster, encompassing both the variables included in the cluster analysis and other relevant psychological variables. RESULTS: Findings suggest that gamblers can be classified into three clusters based on these variables: 1) "high gambling severity and good mental health," 2) "high gambling severity and poor mental health," and 3) "low gambling severity and good mental health." These clusters were differentiated as a function of psychological variables, such as emotional dependence, alexithymia, and stressful life events. CONCLUSIONS: Classifying gamblers according to their profile provides a better understanding of their needs and problems, allowing for a more tailored approach in terms of prevention and intervention strategies.

ABSTRACT

Analyzing why being a victim of violence has led women to have problems with gambling is a field yet to be explored. Thus, the objectives of the present study were (I) analyze the relationship between gambling motives, received psychological violence, and early maladaptive schemas in women; (II) study differences in the study variables in women with and without gambling disorder (GD); (III) analyze the predictive role of violence and schemas in gambling motives; and (IV) analyze the mediating role of schemas in the relationship between violence and gambling motives. The sample comprised 61 women with GD (M = 48.43, SD = 12.78) and 342 women without GD (M = 26.91, SD = 11.47). The results of the present study revealed positive correlations between gambling motives, psychological violence received and early maladaptive schemas. In addition, women with GD scored higher on the study variables. It was also found that early maladaptive schemas based on subjugation and defectiveness may be a vulnerability factor for engaging in gambling to cope with the negative emotions produced by gender violence. From a clinical perspective, knowing the risk factors related to gambling motives in women is crucial to developing effective prevention and intervention programs.

ABSTRACT

There is a growing body of research that seeks to understand the aetiology, consequences and risk factors associated with addictive behaviours in youths. However, research examining the specific profile of adolescent females is very limited. Therefore, the objectives of the present study were, firstly, to explore the differences between attachment, gambling motives (social enhancement and coping), positive and negative affect, and addictive behaviours (gambling, drugs, spending, alcohol and video games) in female adolescents with and without risk of gambling problems. Secondly, the relationships between attachment, gambling motives, positive and negative affect and addictive behaviours were analysed in the subsample of female adolescents with problem gambling Thirdly, we examine the predictive role of positive and negative affect, gambling motives, and attachment in the aforementioned addictive behaviours. The sample was composed of 351 adolescents and young women, of which 312 had no risk of gambling and 39 had gambling problems. The results obtained revealed higher scores in drugs, spending, maternal attachment, and all gambling motives in the group of gambling problems. Likewise, analyses showed that the relevance of the predictor variables (attachment, gambling motives, and affect) varied according to the addiction that was taken as a reference point (i.e., gambling, drugs, spending, alcohol and video games).Consequently, the identification of the possible vulnerability factors for each addiction could be useful in the design of prevention and treatment approaches. In addition, the need for integrated and holistic health- and social- care programmes are suggested in terms of sex and age.

ABSTRACT

Gambling disorder is characterized by a behavioural pattern of dysfunctional gambling that persists despite its negative implications in different areas of people's daily life. One of the most negatively affected areas is the one related to family members. This study aimed, firstly, to study the differences between family members of people with gambling disorder and a general population sample in anger (state, trait, expression-out, expression-in. control-out and control-in), rumination (brooding, reflection and total), and anxiety and depression. The second aim was to analyse the correlation between these variables in the family members of people with gambling disorder, and thirdly, to analyse the mediating role of rumination between anger, anxiety and depression. This study consisted of 170 people, of whom 87 were family members of people with a gambling disorder, and 83 were from the general population. Instruments measuring anger, anxiety, depression, and ruminative responses were administered. Results showed that family members had significantly higher scores in anger (state), depression, anxiety, rumination (total and brooding). Also, results showed that anger correlated positively and significantly with rumination, depression and anxiety, which also correlated positively and significantly with each other. Third, rumination mediated the relationship between the following variables: anger (state) and depression; anger (trait) and anxiety and depression; anger (external expression) and anxiety and depression. A complete mediating effect was found in the latter case and a partial mediating effect in the first two cases. In conclusion, it is found that having a family member with a gambling disorder may increase levels of anger, anxiety, depression and rumination. Furthermore, it is shown that working on rumination may reduce depression and anxiety in family members of gamblers.

ABSTRACT

OBJECTIVE: To describe the creation of an original 3D-printed liquid latex model designed for laparoscopic pyeloplasty (LP) simulation in infants, and to assess its usefulness. MATERIALS AND METHODS: A 3D model of a dilated pelvis and a ureter with ureteropelvic junction obstruction (UPJO) was designed. It was covered in liquid latex, which allowed flexible models to be achieved in order to conduct pyeloplasty in a pelvitrainer. The total price of each model was 6 euros. A nearly-experimental, non-randomized, blind study was carried out, while measuring operating times and OSATS (Objective Structured Assessment of Technical Skills) scores. Following simulation completion, a survey based on Likert scale was conducted to assess overall appearance, texture, usefulness, and probability of recommending the model for regular training. RESULTS: 8 pediatric surgeons spent a median of 71.5 minutes (range: 50-86), and rated the model with a median 20.1/30 (range: 17-24) OSATS score. The model received a 4.25 (range: 3-5) score in terms of overall appearance, a 4.37 (range: 3-5) score in terms of texture, a 4.5 (range: 4-5) score in terms of usefulness, and a 4.6 (range: 4-5) score in terms of probability of recommending the model for regular training. CONCLUSIONS: Our liquid latex model for laparoscopic pyeloplasty simulation is feasible, with favorable preliminary results. Its usefulness in laparoscopic pyeloplasty training is promising.

ABSTRACT

Autoimmune diseases are characterized by a breakdown of immune tolerance partly due to environmental factors. The short-chain fatty acid acetate, derived mostly from gut microbial fermentation of dietary fiber, promotes antiinflammatory Tregs and protects mice from type 1 diabetes, colitis, and allergies. Here, we show that the effects of acetate extend to another important immune subset involved in tolerance, the IL-10-producing regulatory B cells (B10 cells). Acetate directly promoted B10 cell differentiation from mouse B1a cells both in vivo and in vitro. These effects were linked to metabolic changes through the increased production of acetyl-coenzyme A, which fueled the TCA cycle and promoted posttranslational lysine acetylation. Acetate also promoted B10 cells from human blood cells through similar mechanisms. Finally, we identified that dietary fiber supplementation in healthy individuals was associated with increased blood-derived B10 cells. Direct delivery of acetate or indirect delivery via diets or bacteria that produce acetate might be a promising approach to restore B10 cells in noncommunicable diseases.

ABSTRACT

Gambling disorder and other comorbid addictive disorders may have similar underlying affective and motivational patterns. This study aims at examining the association between gambling disorder, comorbid addictive disorders (i.e., alcohol, drugs, spending, and videogames), positive and affective mood, and gambling motives in a community sample. A sample of 1099 adolescents and young adults was recruited from educational centres, from which 569 (51.7%) scored as non-problem gamblers, 42 (3.8%) as at-risk gamblers, and 53 (4.8%) as problem gamblers. Results suggest that enhancement, social, and coping motives are greater among problem gamblers and at-risk gamblers as compared to non-problem gamblers. Problem gamblers scored higher in gambling and comorbid disorders than at-risk gamblers, and also higher in gambling motives and negative mood when compared to non-problem gamblers. Likewise, gambling severity was significantly associated to gambling motives, negative mood, and other addictive disorders. Finally, enhancement motives were predictive of gambling, alcohol, drugs, and spending while controlling for the effect of age, sex, and positive and negative mood. These results shed light into the nature of the relationship between gambling and other comorbid addictions and can be used to tailor prevention and treatment strategies.

ABSTRACT

Emerging Latino communities experience social isolation and lack services tailored to their culture. Few male-to-male promotores (community health workers in Spanish) interventions exist. This 6-month participatory study aimed to improve social support, healthcare access, depressive symptoms, and decrease alcohol consumption among Latino immigrant men. Promotores delivered non-directive social support to participants recruited from community venues. We analyzed baseline and 6-month questionnaires data (n = 89) using paired chi square tests. All participants were immigrants; 47% had not finished high school, 29% had depression symptoms, 35% reported past month binge drinking and 93% were uninsured. The intervention significantly improved having a usual source of care (24 to 43%), doctor's visits (41 to 62%) and dentist's visits (27 to 42%) in the past year. Other outcomes did not improve. Male promotores increased healthcare access among vulnerable Latino men. Addressing drinking behavior and depression may require longer interventions or specialized providers.

ABSTRACT

La ciencia odontológica cuenta con diversas metodologías a la hora de brindar auxilio a la Justicia, tanto en la resolución de casos criminales como en procedimientos de índole civil y laboral. La odontología legal requiere de un trabajo interdisciplinario con las otrasespecialidades odontológicas. En ese contexto, el rol capital del perito odontólogo es contribuir al esclarecimiento de la identidad de unapersona. El diente es susceptible de variantes fisiológicas y patológicas en sus estructuras, como así también estigmas inherentes a los tratamientos restauradores, hechos que confiere información dental que individualiza a una persona. Las piezas dentarias pueden ser utilizadas como un arma en determinadas circunstancias, brindando información relevante sobre los caracteres odontológicos de la víctimay/o del agresor, pudiendo entonces desempeñar la odontología legal un importante rol en la investigación de situaciones de agresión sexual yabuso en todas las edades. El odontólogo en su tarea asistencial tiene la responsabilidad de labrar y documentar de manera fiel y completasu devenir profesional, pudiendo ser requerido por las autoridades encargadas de administrar Justicia en casos de responsabilidad profesional, negligencia, fraude, abuso, e identificación de restos humanos.


Dental science has various methodologies when providing aid to justice, both in solving criminal cases and civil procedures and labor issues.Legal Dentistry requires interdisciplinary work with other dental specialties. In this context, the principal role of the dentist expert is helpclarify the identity of a person. The tooth is subject to physiological and pathological variations in their structures, as well as inherentstigmas restorative treatments, facts which confers dental individualized information to a person. The teeth can be used as a weapon incertain circumstances, providing relevant information about dental characteristics of the victim and/or perpetrator can then LegalDentistry play an important role in investigating cases of sexual assault and abuse in all the ages. The dentist in their care task isresponsible for faithfully document and complete their professional procedure that may be required by the authorities responsible foradministering justice in cases of professional liability, negligence, fraud, abuse, and identification of human remains.

ABSTRACT

El objetivo del presente estudio es describir y comparar los porcentajes de no cumplimentación de dos instrumentos de registro: hoja circulante (HC) y lista de verificación quirúrgica (LVQ), en un mismo entorno quirúrgico para una muestra de pacientes de características similares. Metodología: Estudio descriptivo realizado sobre registros intraquirúrgicos de 3024 pacientes de Cirugía de Ortopedia y Traumatología. 1732 pacientes intervenidos en 2009 con modelo de hoja circulante, cumplimentada al finalizar la intervención y 1292 en 2010 intervenidos con modelo de registro lista de verificación quirúrgica (checklist) cumplimentado durante la intervención en tres tiempos. Se han calculado características descriptivas (media, desviación típica, mínimo y máximo) del porcentaje de no cumplimentación global en ambos registros y el porcentaje de no cumplimentación (intervalo de confianza al 95%) de cada ítem de los registros estudiados. Resultados: Se observa mayor porcentaje de cumplimentación global y, en general, también individual, en la hoja circulante que en la lista de verificación quirúrgica. Conclusiones: El registro intraquirúrgico que mayor porcentaje de cumplimentación ha tenido de manera global ha sido la hoja de circulante y se evidencia la necesidad de implantar estrategias para mejorar el grado de cumplimentación de la LVQ por su relación con la seguridad de pacientes (AU)


The objective of this study is to describe and compare the percentages of non-filling-in two recording instruments: Current sheet and surgical checklist in the same surgical setting for a sample of patients with similar characteristics. Methods: Descriptive study carried out with the intraoperative records of 3024 patients from Orthopedic Surgery and 1732 patients who were operated in 2009 with current sheet model completed at the end of the surgery and 1292 patients in 2010 with surgical checklist as recording model, completed during the intervention in three stages. Descriptive characteristics (mean, standard deviation, minimum and maximum) were calculated from the overall percentage of non-completion in both records, as well as the non-filling-in percentage (and confidence interval at 95%) of each item of the records studied. Results: A higher overall - and also individual, in general- percentage of filling-in is observed in the current sheet than in the surgical checklist. Conclusions: In general terms, the intraoperative recording with the highest percentage of being filled-in has been the circulating sheet and it has been observed the necessity to implement strategies to improve the level of filling-in due to its relationship with surgical clinical safety (AU)

ABSTRACT

Spain's immigrant population has increased 380% in the last decade, accounting for 13.1% of the total population. This fact has led her to become during 2009 the eighth recipient country of international immigrants in the world. The aim of this article is to describe the evolution of mortality and the main causes of death among the Spanish-born and foreign-born populations residing in Spain between 1999 and 2008. Age-standardised mortality rates (ASRs), average age and comparative mortality ratios among foreign-born and Spanish-born populations residing in Spain were computed for every year and sub-period by sex, cause of death and place of birth as well as by the ASR percentage change. During 1999-2008 the ASR showed a progressive decrease in the risk of death in the Spanish-born population (-17.8% for men and -16.6% for women) as well as in the foreign-born one (-45.9% for men and -35.7% for women). ASR also showed a progressive decrease for practically all the causes of death, in both populations. It has been observed that the risk of death due to neoplasms and respiratory diseases among immigrants is lower than that of their Spanish-born counterparts, but risk due to external causes is higher. Places of birth with the greater decreases are Northern Europe, Eastern Europe, Western Europe, Southern Europe, and Latin America and the Caribbean. The research shows the differences in the reduction of death risk between Spanish-born and immigrant inhabitants between 1999 and 2008. These results could contribute to the ability of central and local governments to create effective health policy. Further research is necessary to examine changes in mortality trends among immigrant populations as a consequence of the economic crisis and the reforms in the Spanish health system. Spanish data sources should incorporate into their records information that enables them to find out the immigrant duration of permanence and the possible impact of this on mortality indicators.

ABSTRACT

An electrochemical approach to directly measure the dynamic process of H2 O2 release from cultures of Arabidopsis thaliana cells is reported. This approach is based on H2 O2 oxidation on a Pt electrode in conjunction with continuous measurement of sample pH. For [H2 O2 ] <1 mm, calibration plots were linear and the amperometric response of the electrode was maximum at pH 6. At higher concentrations ([H2 O2 ] >1 mm), the amperometric response can be described by Michaelian-type kinetics and a mathematical expression relating current intensity and pH was obtained to quantitatively determine H2 O2 concentration. At pH 5.5, the detection limit of the sensor was 3.1 µm (S/N = 3), with a response sensitivity of 0.16 Am(-1 ) cm(-2) and reproducibility was within 6.1% in the range 1-5 × 10(-3 ) m (n = 5). Cell suspensions under normal physiological conditions had a pH between 5.5-5.7 and H2 O2 concentrations in the range 7.0-20.5 µm (n = 5). The addition of exogenous H2 O2 , as well as other potential stress stimuli, was made to the cells and the change in H2 O2 concentration was monitored. This real-time quantitative H2 O2 analysis is a potential marker for the evaluation of oxidative stress in plant cell cultures.

ABSTRACT

OBJECTIVES: The role of the microsurgical management of intrinsic brain tumors is to maximize the volumetric resection of the tumoral tissue minimizing the postoperative morbidity. The purpose of our paper has been to study the benefits of an original protocol developed for the microsurgical treatment of tumors located in eloquent motor areas where the navigation and electrical stimulation of motor subcortical pathways have been implemented. MATERIALS AND METHODS: A total of 17 patients operated on for resection of cortical or subcortical tumors in motor areas were included in the series. Preoperative planning for multimodal navigation was done integrating anatomic studies, motor functional MRI (f-MRI) and subcortical pathways volumes generated by diffusion tensor imaging (DTI). Intraoperative neuromonitorization included motor mapping by direct cortical and subcortical electrical stimulation (CS and sCS) and localization of the central sulcus using cortical multipolar electrodes and the N20 wave inversion technique. The location of all cortical and subcortical stimulated points with positive motor response was stored in the navigator and correlated with the cortical or subcortical motor functional structures defined preoperatively. RESULTS: The mean tumoral volumetric resection was 89.1±14.2% of the preoperative volume, with a total resection (≥100%) in twelve patients. Preoperatively a total of 58.8% of the patients had some motor deficit, increasing 24 hours after surgery to 76.5% and decreasing to 41.1% a month later. There was a great correlation between anatomic and functional data, both cortically and subcortically. However, in six cases it was not possible to identify the central sulcus and in many cases fMRI gave contradictory information. A total of 52 cortical points submitted to CS had positive motor response, with a positive correlation of 83.7%. Also, a total of 55 subcortical points had positive motor response, being in these cases 7.3±3.1 mm the mean distance from the stimulated point to the subcortical tract. CONCLUSIONS: The integration of preoperative and intraoperative anatomic and functional studies allows a safe functional resection of the brain tumors located in eloquent areas, compared to the tumoral resection based on anatomic imaging studies. Multimodal navigation allows the integration and correlation among preoperative and intraoperative anatomic and functional data. Cortical motor functional areas are anatomically and functionally located preoperatively thanks to MRI and fMRI and subcortical motor pathways with TDI and tractography. Intraoperative confirmation is done with CS and N20 inversion wave for cortical structures and with sCS for subcortical pathways. With this protocol we achieved a mean of 90% of volumetric resection in cortical and subcortical tumors located in eloquent motor areas with an increase of neurological deficits in the immediate postoperative period that significantly decreased one month later. Ongoing studies will define the safe limits for functional resection taking into account the intraoperative brain shift. Finally, it must be demonstrated if this protocol has any benefit for patients concerning disease free or overall survival.

ABSTRACT

INTRODUCTION: the thermal diffusion flowmetry (TDF) is a technique that allows the measurement of the regional cerebral blood flow (rCBF) through an implanted microprobe in a cerebral region of interest. The monitoring is continuous, real-time and quantitative (ml/100g/min). The purpose of our clinical work has been to show the technical details and preliminary results by using this monitoring technique during the microsurgical management of cerebral aneurysms and along the postoperative period. The aim of the monitoring of the rCBF is to identify and evaluate ischemic events related with the temporary artery clipping or malposition of the final clip. CLINICAL MATERIALS: a total of five patients have been monitored (4 woman and one man with an average age of 50.8 years). Two patients harboured one aneurysm in the middle cerebral artery, other two patients had two aneurysms each one on the internal carotid artery in the exit of the posterior communicating and anterior choroidal artery and the fifth harboured a paraclinoid internal carotid artery aneurysm. All patients were operated on using standard microsurgical techniques through a pterional approach. Surgery was done under neurophysiological monitoring and direct microdoppler fluometry assesment. Just before craniotomy the TDF microprobe was inserted 2.5 cm deep into the white matter through a small burr-hole placed on the coronal line and 2 cm away the midline to measure in the anterior cereral artery vascular sector and 6cm away of the midline to measure in the middle cerebral artery territory. Patients were under continuous monitoring during surgery and along the postoperative period in the recovery unit. A total of 14 temporary artery clippings (between 2-4) with an average total clipping time of 7.2 minutes (ranging 1.6 to 16) and 16 definitive clip replacements (ranging 2 to 8) were done at surgery. Patient with paraclinoid aneurysm was operated on using the retrograde aspiration technique and the internal carotid artery was kept closed 45 mimutes. keeping Some illustrative cases and demonstrative records are presented. CONCLUSIONS: the use of TDF allows a quantitative real-time measurement of the rCBF in the areas of interest monitored during the microsurgical management of the cerebral aneurysms which leads to detect ischemic events helpping to avoid ischemic sequelae. The detection of ischemic events in real time would make possible the use of therapeutic measures ealier and more efficienty.

ABSTRACT

Introducción. La flujometría por difusión termal(FDT) es una técnica que permite, mediante la implantación de una microsonda en una región cerebral de interés, determinar el flujo sanguíneo cerebral regional (FSCr) y su monitorización cuantitativa (ml/100g/min), continua y en tiempo real. El objetivo de nuestro trabajo es mostrar los detalles técnicos y resultados preliminares de esta técnica de monitorización durante la cirugía y el postoperatorio del tratamiento microquirúrgico de los aneurismas cerebrales, donde tendría valor para detectar y cuantificar fenómenos isquémicos relacionados con el clipaje temporal arterial o malposición del clip definitivo. Material clínico. Han sido monitorizados cinco pacientes(4 mujeres y 1 hombre; edad media de 50.8 años),dos de ellos con aneurismas de arteria cerebral media, otros dos con sendos aneurismas de arteria comunicante posterior y coroidea anterior y uno con aneurisma de carótida interna paraclinoideo. Los pacientes fueron intervenidos con técnica microquirúrgica y clipaje de los aneurismas a través de un abordaje pterional. Se utilizó monitorización neurofisiológica peroperatoria y flujometría con microdoppler. Inmediatamente antes de la craneotomía se procedió a la colocación de la microsonda de FDT a través de un minitrépano sobrela línea coronal, en territorio de la arteria cerebral anterior (2 cm de línea media) o de la cerebral media(6 cm de línea media) y en sustancia blanca, a unos 2.5cm de profundidad. Los pacientes fueron monitorizados durante la cirugía y el tiempo en que estuvieron en la Unidad de Reanimación. Se realizaron un total de 14 clipajes temporales (rango 2-4) con un tiempo medio de clipaje de 7.2 min (rango 1.6-16) (..) (AU)

ABSTRACT

Clinical and imaging findings of a series of 14 internal carotid artery bifurcation aneurysms microsurgically treated are presented. A total of 10 lesions were diagnosed before rupture and 4 patients presented with subarachnoidal hemorrhage and frontobasal intracerebral bleeding. Diagnosis was done using neuroimaging (CT scan, angio-CT-3D, angio-MRI, angiography) but patients with ruptured aneurysms were treated with the sole information provided by the angio-CT-3D. The average fundus size was 8.4mm (3-13.3) and the average neck size was 6.8mm (3-9.6), being the fundus-to-neck ratio 1.32 (0.46-2.05). All lesions were microsurgically treated through a pterional approach with the help of temporary clipping of the afferent vessels in all cases. We used peroperative neuroprotective, neuromonitorization and micro-doppler cerebral flow measurement. Clinical results were excellent with 13 patients GOS grade 5 and one grade 4 three month afterwards of hospital discharge and complete exclusion of the lesion in angiographic controls done solely in patients with ruptured lesions.

ABSTRACT

Se presentan los hallazgos clínicos y de imagen deuna serie de 14 aneurismas de bifurcación de la arteriacarótida interna tratados microquirúrgicamente. Untotal de 10 lesiones no se habían roto y las 4 restantesse presentaron con hemorragia subaracnoidea y hematomafrontobasal. El diagnóstico se realizó con técnicasde neuroimagen (TAC, angio-TAC-3D; angio-RNM,angiografía), aunque los pacientes con aneurismasrotos fueron intervenidos con los hallazgos proporcionadospor el angio-TAC-3D. El tamaño medio del sacoera de 8.4mm (3-13.3) y el del cuello 6.8mm (3-9.6),con una relación saco/cuello de 1.32 (0.46-2.05). Laslesiones se trataron por vía pterional sin incidencias ycon ayuda de clipaje temporal en todos los casos. Seutilizaron técnicas peroperatorias de neuroprotección,neuromonitorización y determinación de flujo vascularcon micro-doppler. Los resultados clínicos han sidoexcelentes, con 13 pacientes con GOS 5 y uno con GOS4 a partir de los tres meses del alta y exclusión del aneurismaen los controles angiográficos postquirúrgicosrealizados en los pacientes con aneurisma roto (AU)
