RESUMEN

Associations and families demand the need to raise awareness of the implications in the cognitive and behavioral development of children with Fetal Alcohol Spectrum Disorder (FASD) that affect their learning and school participation. This study aims to generate a profile of executive and behavioral functioning in children and adolescents diagnosed with FASD. A probabilistic sampling by clusters (associations for individuals with FASD) is applied. The sample is composed of 66 families from three associations. The BRIEF-2 and SENA tests were administered to assess executive and behavioral functioning domains. Data analysis found that the executive and behavioral functioning profile of individuals with FASD varies with age, with greater impairment in middle and late adolescence. Likewise, the domain of executive functioning most affected in any of the developmental stages is working memory. Finally, cognitive impairment in the executive functioning domains has a direct impact on the social and adaptive functioning of people with FASD.

RESUMEN

Resumen Objetivos. Identificar si existen mejoras en la interacción social de jóvenes con discapacidad intelectual a través del uso de una metodología basada en el juego de rol. Método. Se realizó un estudio de diseño mixto a partir de un programa de intervención breve, de ocho sesiones de duración, con un total de siete participantes. Para la recolección de datos, se utilizaron técnicas cualitativas y cuantitativas como la observación sistemática, la observación directa no sistematizada y la Escala de Autoevaluación de Habilidades Sociales. Resultados. La intervención arrojó resultados modestos. La prueba W de Wilcoxon muestra diferencias significativas a nivel general. Las observaciones evidencian cambios en los comportamientos de los participantes, sobre todo en lo referente a respuestas alternativas a la agresión, la cuales fueron rápidamente sustituidas por estrategias pacíficas y actitudes dialogantes.


Abstract Objectives. The objective of this study was to identify if there are improvements in social interaction in young people with intellectual disabilities, using a methodology based on role playing. Method. A mixed design study based on a brief intervention program of eight sessions, with a total of seven participants, was used. Qualitative and quantitative techniques were used for data collection: systematic observation, non-systematized direct observation and the Social Skills Self-Assessment Scale. Results. The intervention yielded modest results. The Wilcoxon W test shows significant differences at the general level. Observations show changes in participants' behaviors, especially in terms of alternative responses to aggression, which were quickly replaced by peaceful strategies and dialogic attitudes.

RESUMEN

ABSTRACT It is clear that physical education is considered a compulsory subject and as such should be la-belled as an important subject, but this perspective is not always shared by the educational community. The aim of this study was to explore the perception of families with children enrolled in compulsory education about the subject of physical education. To this end, an ad hoc questionnaire was administered, consisting of 15 questions, two of which were socio-demographic in nature and the rest of which were Likert-type responses. The study is a non-experimental, descriptive, cross-sectional study. The study sample consisted of a total of 120 respondents (M=40.28 years; SD= 6.95). Participants were selected through non-probability purposive sampling. The results showed a lack of knowledge regarding the subject of physical education which implies that there are diverse opinions about the functioning and the proposed aim of this subject. However, physical education should be seen as an essential subject for the integral development of the student.


RESUMO É evidente que a educação física é considerada uma disciplina obrigatória e como tal deve ser rotulada como uma disciplina importante, mas esta perspectiva nem sempre é partilhada pela comunidade educativa. O objectivo deste estudo era explorar a percepção das famílias com crianças matriculadas no ensino obrigatório sobre o tema da educação física. Para o efeito, foi administrado um questionário ad hoc, constituído por 15 perguntas, duas das quais de natureza sócio-demográfica e as restantes respostas eram do tipo Likert-. O estudo é um estudo não-experimental, descritivo, de corte transversal. A amostra do estudo consistiu num total de 120 respondentes (M=40,28 anos; SD=6,95). Os participantes foram seleccionados através de amostragem sem fins lucrativos. Os resultados mostraram uma falta de conhecimento sobre o tema da educação física, o que implica que existem opiniões diversas sobre o funcionamento e o objectivo proposto para este tema. No entanto, a educação física deve ser vista como um assunto essencial para o desenvolvimento integral do estudante.

RESUMEN

The most appropriate duration of anticoagulant treatment for cancer-associated venous thromboembolism (CAT) remains unclear. We have conducted a prospective multicenter study in CAT patients with more than 6 months of anticoagulant treatment to predict the risk of venous thromboembolism (VTE) recurrence after anticoagulation discontinuation. Blood samples were obtained when patients stopped the anticoagulation, at 21 days and at 90 days. In each sample we assessed different coagulation-related biomarkers: D-dimer (DD), high-sensitivity C-reactive protein (hs-CRP), P-selectin (PS), phospholipids, soluble tissue factor, factor VIII and the thrombin generation test. It was evaluated 325 CAT patients and 166 patients were included in the study, mean age 64 ± 17 years. VTE recurrence until 6 months after stopping anticoagulation treatment was 9.87% [95% confidence interval (CI): 6−15]. The biomarkers sub-distribution hazard ratios were 6.32 for ratio DD basal/DD 21 days > 2 (95% CI: 1.82−21.90), 6.36 for hs-CRP > 4.5 (95% CI: 1.73−23.40) and 5.58 for PS > 40 (95% CI: 1.46−21.30) after 21 days of stopping anticoagulation. This is the first study that has identified the DD ratio, hs-CRP and PS as potential biomarkers of VTE recurrence in cancer patients after the discontinuation of anticoagulation treatment. A risk-adapted strategy may allow the identification of the optimal time to withdraw the anticoagulation in each CAT patient.

RESUMEN

Given the characteristics of people with Autism Spectrum Disorder, it is evident the difficulties they show in the development of social skills. The scarce participation of people with Autism Spectrum Disorder in group sports can be taken as a reference. The aim of this study was to analyse the impact of football on the development of social skills in children with Autism Spectrum Disorder. In order to measure the sporting impact, it was necessary to implement a football training programme with the intention of evaluating different social skills. Thirteen children participated in the programme, all of them with a diagnosis of Autism Spectrum Disorder and with a severity level of 1. The study was based on a pre-experimental, pre-test/post-test design. Non-parametric tests were used for the statistical analysis, applying the Wilcoxon test. Two specific tools on social skills were used for data collection. The results showed a generalised improvement in the dimensions linked to the social skills assessed. This highlights the possibility of considering group sport as an alternative to be taken into account to work on and enhance social skills in children with Autism Spectrum Disorder.

RESUMEN

Implant migration into the nasal fossa is a rare complication and it requires extraction by anterior rhinoscopy. We report a clinical case of placement of short dental implants, fixed or intruded in the nasal fossa floor, which was aspirated by the patient and spontaneously expelled a few days later. To the best of our knowledge, there have been no reports of spontaneously expulsion through the nasal cavity. Key words:Dental implant, nasal cavity, accidental migration.

RESUMEN

Anemia is a common condition in cancer patients and is associated with a wide variety of symptoms that impair quality of life (QoL). However, exactly how anemia affects QoL in cancer patients is unclear because of the inconsistencies in its definition in previous reports. We aimed to examine the clinical impact of anemia on the QoL of cancer patients using specific questionnaires. We performed a post-hoc analysis of a multicenter, prospective, case-control study. We included patients with cancer with (cases) or without (controls) anemia. Participants completed the European Organization for Research and Treatment of Cancer Quality of Life questionnaire version 3.0 (EORTC QLQ-C30) and Euro QoL 5-dimension 3-level (EQ-5D-3L) questionnaire. Statistically significant and clinically relevant differences in the global health status were examined. From 2015 to 2018, 365 patients were included (90 cases and 275 controls). We found minimally important differences in global health status according to the EORTC QLQ-C30 questionnaire (case vs. controls: 45.6 vs. 58%, respectively; mean difference: -12.4, p < 0.001). Regarding symptoms, cancer patients with anemia had more pronounced symptoms in six out of nine scales in comparison with those without anemia. In conclusion, cancer patients with anemia had a worse QoL both clinically and statistically.

RESUMEN

In symptomatic acute pulmonary embolism (PE), the presence of deep vein thrombosis (DVT) is a risk factor for 30- and 90-day mortality. In patients with cancer and incidental PE, the prognostic effect of concomitant incidental DVT is unknown. In this retrospective study, we examined the effect of incidental DVT on all-cause mortality in such patients. Adjusted Cox multivariate regression analysis was used for relevant covariates. From January 2010 to March 2018, we included 200 patients (mean age, 65.3 ± 12.4 years) who were followed up for 12.5 months (interquartile range 7.4-19.4 months). Of these patients, 62% had metastases, 31% had concomitant incidental DVT, and 40.1% (n = 81) died during follow-up. All-cause mortality did not increase in patients with DVT (hazard ratio [HR] 1.01, 95% confidence interval [CI] 0.43-2.75, p = 0.855). On multivariate analysis, weight (adjusted HR 0.96, 95% CI 0.92-0.99, p = 0.032), and metastasis (adjusted HR 10.26, 95% CI 2.35-44.9, p = 0.002) were predictors of all-cause mortality. In conclusion, low weight and presence of metastases were associated with all-cause mortality, while presence of concomitant DVT was unrelated to poorer survival.

RESUMEN

Introducción: Las escalas predictivas de recurrencias de ETV son útiles para decidir la duración del tratamiento anticoagulante. Aunque hay varias escalas, desconocemos la aplicabilidad de las mismas en nuestro medio. Por ello nos planteamos validar el modelo predictivo DASH y el nomograma de Viena a 12 meses. Métodos: Estudio retrospectivo de pacientes consecutivos no seleccionados con ETV no provocada desde 2006 hasta 2014. Comparamos la capacidad de predecir recurrencias de ETV de la escala DASH y el nomograma de Viena. La validación se realizó estratificando a los pacientes como de bajo o alto riesgo, según cada escala (discriminación) y comparando las recurrencias observadas frente a las esperadas (calibración). Resultados: De 353 pacientes evaluados, se analizaron 195, con una edad media de 53,5+/-19 años. Hubo 21 recurrencias a 1 año (10,8%, IC95%: 6,8-16%). Según la escala DASH, fueron catalogados de bajo riesgo el 42%, observando ETV recurrente en el grupo de bajo fue del 4,9% (IC95%: 1,3-12%) vs. el grupo de alto riesgo en que fue del 15% (IC95%: 9-23%) (p < 0,05). Según el nomograma de Viena, fueron catalogados de bajo riesgo el 30%, observando ETV recurrente en el grupo de bajo vs. alto riesgo en el 4,2% (IC95%: 0,5-14%) vs. 16,2% (IC95%: 9,9-24,4%) (p < 0,05). Conclusiones: Nuestro estudio valida la escala DASH y el nomograma de Viena en nuestra población. El modelo predictivo DASH sería el más aconsejable, tanto por su sencillez como por la capacidad de identificar a más pacientes de bajo riesgo frente al nomograma de Viena (42% vs. 30%)


Introduction: Scales for predicting venous thromboembolism (VTE) recurrence are useful for deciding the duration of the anticoagulant treatment. Although there are several scales, the most appropriate for our setting has not been identified. For this reason, we aimed to validate the DASH prediction score and the Vienna nomogram at 12 months. Methods: This was a retrospective study of unselected consecutive VTE patients seen between 2006 and 2014. We compared the ability of the DASH score and the Vienna nomogram to predict recurrences of VTE. The validation was performed by stratifying patients as low-risk or high-risk, according to each scale (discrimination) and comparing the observed recurrence with the expected rate (calibration). Results: Of 353 patients evaluated, 195 were analyzed, with an average age of 53.5 ± 19 years. There were 21 recurrences in 1 year (10.8%, 95% CI: 6.8%-16%). According to the DASH score, 42% were classified as low risk, and the rate of VTE recurrence in this group was 4.9% (95% CI: 1.3%-12%) vs. the high-risk group that was 15% (95% CI: 9%-23%) (p <.05). According to the Vienna nomogram, 30% were classified as low risk, and the rate of VTE recurrence in the low risk group vs. the high risk group was 4.2% (95% CI:0.5%-14%) vs. 16.2% (95% CI: 9.9%-24.4%) (p <.05). Conclusions: Our study validates the DASH score and the Vienna nomogram in our population. The DASH prediction score may be the most advisable, both because of its simplicity and its ability to identify more low-risk patients than the Vienna nomogram (42% vs. 30%)

RESUMEN

BACKGROUND: Optimal duration of anticoagulation for cancer-associated thrombosis (CAT) remains unclear. This study assessed D-dimer (DD) and high-sensitivity C-reactive protein (hs-CRP) levels after the withdrawal of anticoagulation treatment to predict the risk of venous thromboembolism (VTE) recurrence among patients with CAT. METHODS: Prospective, multicentre study to evaluate CAT with ≥3 months of anticoagulation that was subsequently discontinued. Blood samples were taken when patients stopped the anticoagulation and 21 days later to determine the DD and hs-CRP levels. All patients were followed up for 6 months to detect VTE recurrence. RESULTS: Between 2013 and 2015, 325 patients were evaluated and 114 patients were ultimately enrolled in the study. The mean age was 62 ± 14 years and nearly 40% had metastasis. Ten patients developed VTE recurrence within 6 months (8.8%, 95% confidence interval [CI]: 4.3-15.5%). The DD and hs-CRP levels after 21 days were associated with VTE recurrence. The subdistribution hazard ratios were 9.82 for hs-CRP (95% CI: 19-52) and 5.81 for DD (95% CI: 1.1-31.7). CONCLUSIONS: This study identified that hs-CRP and DD were potential biomarkers of VTE recurrence after discontinuation of anticoagulation in CAT. A risk-adapted strategy could identify low-risk patients who may benefit from discontinuation of anticoagulation.

RESUMEN

INTRODUCTION: The safety and efficacy of low-molecular-weight heparin (LMWH) treatment in patients with cancer-associated thrombosis (CAT) beyond 6months are unknown. Our aim was to determine the safety of long-term tinzaparin use in patients with CAT. METHODS: We performed a prospective, open, single arm, multicentre study in patients with CAT receiving treatment with tinzaparin. We evaluated the rate of clinically relevant bleeding events (major and non-major clinically relevant bleeding) and venous thromboembolism (VTE) recurrence. RESULTS: A total of 247 patients were recruited, with a crude incidence of major bleeding of 4.9% (12/247). The rate of clinically relevant bleeding during months 1-6 and 7-12, was 0.9% [95% confidence interval (95% CI) 0.5 to 1.6%] and 0.6% (95% CI 0.2 to 1.4%) (p=0.5) per patient and month, respectively. Male gender showed greater risk for clinically relevant bleeding with a hazard ratio (HR) of 2.97 (95% CI 1.01 to 8.1; p=0.02). The incidence of VTE recurrence at months 1-6 and 7-12 was 4.5% (95% CI 2.2 to 7.8%) and 1.1% (95% CI 0.1 to 3.9%), respectively. One patient died due to VTE recurrence and two because of severe bleeding. CONCLUSIONS: Treatment with tinzaparin beyond 6months is safe in patients with CAT.

RESUMEN

OBJECTIVE: A study was designed to measure of the incidence of bisphosphonate-related osteonecrosis of the jaws (BRONJ) following tooth extraction in patients receiving or who have received intravenous bisphosphonates (Zometa, zoledronic acid). METHOD AND MATERIALS: A prospective cohort study was made of 36 patients subjected to 62 tooth extractions. All these 36 patients had been treated or were receiving treatment with zoledronic acid. RESULTS: The incidence of BRONJ following 62 tooth extractions in patients treated with zoledronic acid 4 months after extraction was 14.5%. CONCLUSION: No statistically significant associations were found with patient age, sex, hygiene index, total treatment time, surgical difficulty, or extraction site. However, the factors that significantly influenced the final presence of osteonecrosis were related to tooth extractions in the absence of periodontal disease, and if sockets remained unhealed at the month of extraction.

RESUMEN

PURPOSE: Mental neuropathy (MN) is characterized by the presence of a sensory defect in the form of paresthesias or dysesthesias in the territory innervated by the mental nerve. MN may be the first manifestation of systemic cancer, a symptom of spread of an established tumor, or a sign of infiltration in an intraoral lesion. In any of these cases, the symptom is indicative of a very poor patient prognosis. MATERIALS AND METHODS: A total of 22 cancer patients with chin paresthesia were studied. Group 1 comprised patients with chin paresthesia who had a primary tumor in some other region at a distance from the oral cavity or maxillofacial zone. Group 2 in turn comprised patients with primary malignancies of the oral and/or maxillofacial territory and who likewise presented with chin paresthesia. Data were collected relating to patient age, gender, primary intraoral lesion (location, size, histologic diagnosis), primary systemic tumor, and mean patient survival. RESULTS: Group 1 consisted of 11 patients (8 men and 3 women), aged between 36 and 81 years (mean, 58.09 +/- 14.99 years), with different systemic cancers. The mean survival after the diagnosis of chin paresthesia was 14.8 +/- 16.5 months, and only 1 patient was still alive after 9 months. Group 2 consisted of 11 patients (8 men and 3 women), aged between 33 and 72 years (mean, 56.18 +/- 15.69 years). All presented with oral squamous cell carcinoma, with the single exception of 1 case of fibrosarcoma. In this group the mean survival of the 8 patients who died was 28.2 +/- 29.6 months. Three patients survived for a mean of 17 months. CONCLUSIONS: Chin paresthesia is a very important prognostic symptom determining the degree of infiltration of intraoral lesions, and in some cases it may be indicative of the existence of a primary tumor (identified or otherwise), with poor short-term survival--given that 81.9% of the patients studied (18 cases) had died before a mean of 20 months. Although mean survival was shorter (14.8 months) among the patients in group 1 than in group 2 (28.2 months), the difference was not statistically significant.

RESUMEN

The protective effect of the 21-aminosteroid U-74389G was studied in an experimental model of partial ischaemia reperfusion liver injury. Previous studies have proven the remarkable potency of 21-aminosteroids to prevent oxidant-induced cell injury in vitro and in vivo. However, the capability of these compounds to limit oxidative injury in clinical trials has been considered to be less certain. The potential protective effect exerted by U-74389G on reduced and prolonged models of ischaemia reperfusion liver injury was studied in male rats subjected to 75 min. of segmentary hepatic ischaemia followed by 1 or 24 hr of reperfusion. Liver injury was evaluated by measuring serum levels of liver enzymes and by histopathological studies. The oxidative status of liver cells was measured by evaluating the levels of liver lipid peroxidation products such as malondialdehyde and the levels of reduced glutathione. Our results lead us to think that treatment with U-74389G (6 mg/kg) does not bring about any protective effect neither in the levels of transaminases nor in the percentage of hepatocellular necrosis and cellular infiltration observed in any reperfusion-period groups. In fact and in contrast with our expectations, U-74389G seemed to increase enzyme release. Furthermore, at the dose used, this 21-aminosteroid is not capable of inhibiting the lipoperoxidation processes, although it induced an important increase of GSH levels at any time-period of reperfusion. This last finding seem to suggest that U-74389G could increase the resistance to oxidant-induced liver tissue damage. However, our results show that, at the dose used, this compound did not exert any protective effect on liver tissue, thus explaining, at least partially, the absence of beneficial effects on the part of these compounds in clinical trials carried out to limit organ injury in transplants.
