RESUMO

Sensitivity of forest mortality to drought in carbon-dense tropical forests remains fraught with uncertainty, while extreme droughts are predicted to be more frequent and intense. Here, the potential of temporal autocorrelation of high-frequency variability in Landsat Enhanced Vegetation Index (EVI), an indicator of ecosystem resilience, to predict spatial and temporal variations of forest biomass mortality is evaluated against in situ census observations for 64 site-year combinations in Costa Rican tropical dry forests during the 2015 ENSO drought. Temporal autocorrelation, within the optimal moving window of 24 months, demonstrated robust predictive power for in situ mortality (leave-one-out cross-validation R2  = 0.54), which allows for estimates of annual biomass mortality patterns at 30 m resolution. Subsequent spatial analysis showed substantial fine-scale heterogeneity of forest mortality patterns, largely driven by drought intensity and ecosystem properties related to plant water use such as forest deciduousness and topography. Highly deciduous forest patches demonstrated much lower mortality sensitivity to drought stress than less deciduous forest patches after elevation was controlled. Our results highlight the potential of high-resolution remote sensing to "fingerprint" forest mortality and the significant role of ecosystem heterogeneity in forest biomass resistance to drought.

RESUMO

BACKGROUND AND AIMS: Spondyloarthritis (SpA) is a group of autoinflammatory disorders, of which the primary extra-articular manifestation is inflammatory bowel disease (IBD). The oral cavity being a part of gastrointestinal tract, is significantly compromised in IBD, and in many cases, it is the first site of clinical manifestations of IBD. This study aimed to identify changes in the oral mucosa associated with the onset of IBD and their association with endoscopic/histological findings. MATERIALS AND METHODS: The study assessed 80 patients with SpA and 52 healthy controls. Oral, rheumatological, and gastroenterological assessments were performed. The ileocolonoscopy was performed via digital magnification chromoendoscopy. The statistical analysis consisted of Chi-square, Fisher's exact, and multiple correspondence discriminant analysis tests. RESULTS: From the disease cohort, 63.0% patients showed oral lesions (p = 0.050). These manifestations ranged from gingivitis (55.0%, p = 0.001), aphthous stomatitis (3.8%, p = 0.091), angular cheilitis (2.6%, p = 0.200), and perioral erythema with scaling (1.3%, p = 0.300). All patients who presented with alterations in colonic mucosa also had oral lesions associated with IBD (p = 0.039), specifically gingivitis/aphthous stomatitis (p = 0.029). CONCLUSION: The patients with SpA without IBD present significant oral signs and symptoms. Gingivitis seems to be the most relevant because of its associations with early endoscopic and histological findings. CLINICAL RELEVANCE: An integral approach to the diagnostic tests that includes evaluations of oral, rheumatological and gastroenterological tissues may favor timely attention and improve patients' quality of life.

RESUMO

CASE: Background: Metastatic Crohn's disease (MCD) is an unusual cutaneous manifestation in Crohn's disease (CD), and concomitant oral and vulvar involvement is even more unusual. It can debut with cavity lesions oral such as canker sores, ulcers, lip edema, granulomatosis, dry mouth, abscesses in the salivary ducts, erythema, gingivitis, glossitis, among others, however, simultaneous compromise with several oral lesions and so severe with loss of multiple pieces dental is very rare. CASE PRESENTATION: Patient in the fourth decade of life with a family history of autoimmunity who debuts with severe oral manifestations with a requirement for extraction of 14 teeth, severe gingivitis, smooth tongue and glossitis, aphthous stomatitis, ulcers, lip edema and angular cheilitis, without clear cause, and in management by the oral pathology group. Associated with this, there was vulvo-perineal compromise with ulcerated, inflammatory, erythematous and infiltrated lesions. It was initially suspected of Behçet's disease, HLA B51 was performed, it was negative, also, negative pathergy test, and no other suggestive systemic findings. A vulvar biopsy was performed with marked edema of the dermis, dilated lymphatics with perivascular and interstitial lymphoplasmacytic infiltrate and noncaseating granulomas, negative for microorganisms. At this level, it was compatible with MCD, without presence of gastrointestinal symptoms and calprotectin levels in stool in normal range. High and low endoscopic studies and capsule endoscopy were performed in small intestine, without alterations, it was managed by dermatology with topical steroids and by dentistry with dental implants. It was considered patient with inflammatory bowel disease (IBD) type CD with severe extraintestinal manifestations (EIM), although it did not present compromise intestinal treatment, it was decided to start treatment with anti-TNF initially with adalimumab developing paradoxical psoriasis, later treatment with infliximab, again with presentation of severe paradoxical psoriasis, for which it was suspended. Cyclosporine was also used as an immunomodulator, presenting intolerable tachycardia. 18 months after these symptoms, she presented episcleritis of the left eye and begins with colicky abdominal pain and average diarrheal stools 5-a-day, it was performed high and low endoscopic studies without alterations and new capsule endoscopic of small intestine documenting Crohn's enteritis involving the duodenum, jejunum and ileum, considering a patient with IBD type CD, with EIM with vulvo-perineal compromise, severe oral involvement and episcleritis. Currently is under management with azathioprine and Ustekinumab, with clinical improvement significant. CONCLUSIONS: MCD represents a diagnostic challenge, it can debut without gastrointestinal involvement, and its clinical and histopathological findings simulate other entities. A timely diagnosis is required to seek early benefit in the patient.

RESUMO

BACKGROUND: Spondyloarthritis (SpA) is a heterogeneous group of chronic autoinflammatory disorders that can present extra-articular gastrointestinal manifestations. Among them is mainly inflammatory bowel disease (IBD). Although IBD mainly affects the intestinal tract, it can include early manifestations evident in the oral cavity. No comparative data on these oral manifestations in patients with SpA were found in the literature. OBJECTIVE: To identify oral clinical manifestations due to changes in the oral mucosa associated with IBD in patients with SpA without a diagnosis of IBD and associate them with endoscopic and histological findings. METHODS: 80 patients with SpA and 52 healthy controls were evaluated. They were assessed intra- and extra-orally, following the modified World Health Organization guideline. In addition, by clinical parameters of rheumatological, gastrointestinal and laboratory activity. Ileocolonoscopy was performed with digital chromoendoscopy with magnification and histological analysis. Comparative analyzes were performed by Chi square tests, Fisher's exact tests, confirmed by univariate regression and discriminant analysis of multiple correspondences. Institutional ethics committee approval cod-2017-023. RESULTS: The patients with SpA had 56% male gender, mean age of 42.8 years (SD ± 10.4) and a BMI in the range of 23.9 - 28.4. The healthy controls, 54% of the male gender with an average age of 41 years (SD ± 13.6) and a body mass index-BMI in the range of 22.9 - 27.6. The patients reported smoking only in 6.2%, however as a smoking history in 31% and passive smokers (15%), the majority employed (41%), married (56%) and professionals (49%). Of the healthy controls, they smoked (15%), with a history of smoking (31%), passive smokers (21%), the majority employed (77%), with their own home (67%), and professionals (54%). The patients with SpA reported a greater presence of some signs and symptoms of gastrointestinal origin 69%, while in the controls it was 7.7% (p = 0.001). Forty one of them were referred to colonoscopy with magnification being in 17.1 % changes in the mucosa of the rectum and in the same frequency changes in the mucosa of the sigmoid colon. Regarding the ileum, changes in the mucosa were evidenced in 41.5% of the cases. The presence of oral lesions was evident and predominated in them (63%) compared to controls p = 0.050. The main oral lesions associated with IBD were gingivitis (55%) (p = 0.001), followed by aphthous stomatitis (3.8%), angular cheilitis (2.6%) and perioral erythema with scaling (1.3%). 100% of the patients who presented alteration of the colonic mucosa presented oral lesions associated with IBD (p = 0039), which was also significantly associated with the presence of gingivitis/aphthous stomatitis (p = 0.029). CONCLUSION: Patients with SpA without a diagnosis of IBD have more oral signs and symptoms compared to healthy controls. Gingivitis is important given its association with early endoscopic and histological findings. Manifestations in the oral cavity can precede intestinal manifestations, therefore the clinical assessment by the oral pathologist in conjunction with gastroenterology and rheumatology allows a timely referral to gastroenterology and an endoscopic and histological evaluation, impacting the quality of life of patients.

RESUMO

Drought-related tree mortality is now a widespread phenomenon predicted to increase in magnitude with climate change. However, the patterns of which species and trees are most vulnerable to drought, and the underlying mechanisms have remained elusive, in part due to the lack of relevant data and difficulty of predicting the location of catastrophic drought years in advance. We used long-term demographic records and extensive databases of functional traits and distribution patterns to understand the responses of 20-53 species to an extreme drought in a seasonally dry tropical forest in Costa Rica, which occurred during the 2015 El Niño Southern Oscillation event. Overall, species-specific mortality rates during the drought ranged from 0% to 34%, and varied little as a function of tree size. By contrast, hydraulic safety margins correlated well with probability of mortality among species, while morphological or leaf economics spectrum traits did not. This firmly suggests hydraulic traits as targets for future research.

RESUMO

We calculated the population density of the critically endangered Callicebus oenanthe in the Ojos de Agua Conservation Concession, a dry forest area in the department of San Martin, Peru. Results showed significant differences (p < 0.01) in group densities between forest boundaries (16.5 groups/km2, IQR = 21.1-11.0) and forest interior (4.0 groups/km2, IQR = 5.0-0.0), suggesting the 2,550-ha area harbours roughly 1,150 titi monkeys. This makes Ojos de Agua an important cornerstone in the conservation of the species, because it is one of the largest protected areas where the species occurs.

RESUMO

Herbivorous insects alter biogeochemical cycling within forests, but the magnitude of these impacts, their global variation, and drivers of this variation remain poorly understood. To address this knowledge gap and help improve biogeochemical models, we established a global network of 74 plots within 40 mature, undisturbed broadleaved forests. We analyzed freshly senesced and green leaves for carbon, nitrogen, phosphorus and silica concentrations, foliar production and herbivory, and stand-level nutrient fluxes. We show more nutrient release by insect herbivores at non-outbreak levels in tropical forests than temperate and boreal forests, that these fluxes increase strongly with mean annual temperature, and that they exceed atmospheric deposition inputs in some localities. Thus, background levels of insect herbivory are sufficiently large to both alter ecosystem element cycling and influence terrestrial carbon cycling. Further, climate can affect interactions between natural populations of plants and herbivores with important consequences for global biogeochemical cycles across broadleaved forests.

RESUMO

Excessive internet gaming in high prevalence is a very common problem that has been increasing in recent years, especially in teenagers and university students. However, there is a lack of psychometric evaluation for Internet Gaming Disorder in the Latin American context, particularly in Ecuador. This paper aims to examine the psychometric properties of the Spanish version of the Internet Gaming Disorder test (IGD-20 test) in university and high school students (n=2931, Mage=15.99, 57.22% male and 42.51% female). The validation process was performed using one, two, five and six factors taking into account the Spanish, Chinese, Korean, Arabic and Turkish contexts. After checking the models proposed to date, the best fit model was the one with a single factor. Using two samples according to gender (male, female), the invariance has been confirmed with an excellent internal consistency. All, α=0.94; Male, α=0.93; Female, α=0.93). Furthermore, we performed correlation analyses between the IGD-20 Test and socio-demographic variables, and finally, the IGD-20 Test applied to Ecuadorian teenagers and young people demonstrated good psychometric properties.

RESUMO

OBJECTIVE: Kidney transplantation process involves a series of challenges such as the shortage of organs worldwide for a population waiting for a first and subsequent kidney transplants and the search forthe most appropriate graft for each recipient, optimizing the ischemia time as much as possible, minimizing the impact of surgery and subsequent immunosuppressive therapy. METHODS: We carry out a review of the different advances and lines of research in the different areas involved in the kidney transplantation process from strategies focused on increasing the donor pool, enabling the expansion of living donor programs as well as orga preservation strategies previous to transplantation surgery.The arrival of robotic surgery in the field of kidney transplantation has been an important milestone in the last decade, showing improvements compared to traditional open surgery, maintaining satisfactory functional results, although its implementation is currently reduced with technical limitations in the extension to any type of recipient. New immunosuppressive agents that minimize potential side effects or reduce anticalcineurinic drugsdoses are also important lines of research. CONCLUSIONS: The future of kidney transplantation involves the search for increasingly global strategies to improve the supply of organs, improvements in the conditioning and preservation of grafts or the global development of minimally invasive surgery in the different areas of kidney transplantation. The weight of biotechnology and gene therapies represent promising tools in the field of tissue generation or targeted immunosuppressive therapies.


OBJETIVO: El proceso del trasplante renal conlleva una serie de retos como son la escasez de órganos para una población a la espera de un primery sucesivos trasplantes renales y la búsqueda del injertomás apropiado para cada receptor optimizando al máximo el tiempo de isquemia, minimizando el impactode la cirugía y posterior terapia inmunosupresora.MÉTODOS: Realizamos una revisión de los diferentes avances y líneas de investigación en las diferentes etapas que conlleva el proceso del trasplante renal desdelas estrategias centradas a incrementar el pool de donantes,posibilitar la expansión de programas de donante vivo así como las estrategias de preservación del órgano previamente a la cirugía del implante.El desembarco de la cirugía robótica en el campo del trasplante renal ha sido un hito importante en la últimadécada, arrojando mejoras frente a la tradicional cirugía abierta manteniendo unos resultados funcionalessatisfactorios aunque su implantación es reducida en la actualidad con limitaciones técnicas en la extensión a cualquier tipo de receptor. Nuevos agentes inmunosupresores que minimicen los potenciales efectos secundarios o consigan reducir las dosis de anticalcineurínicos son también líneas importantes de investigación. CONCLUSIONES: El futuro del trasplante renal pasa por la búsqueda de estrategias cada vez más globales para mejorar la oferta de órganos, mejoras en el acondicionamiento y preservación de los injertos o el desarrollo a escala global de la cirugía mínimamente invasiva en los diferentes ámbitos del trasplante renal. El peso de las biotecnologías y terapias génicas suponen herramientas prometedoras en el campo de la generación de tejidos o terapias inmunosupresoras dirigidas.

RESUMO

The burnout syndrome is a negative experience for athlete development and it has been demonstrated that it gets worse when a sport is practiced in an obsessive way. Interventions with a positive view towards sports could be a protective factor to boost the athlete's wellbeing. The aim of the present study was to analyse the mediator effect from social support, the relationship between the burnout, positivity and passion in young Mexican athletes. The sample was composed by 452 Mexican athletes, males and females (women 45%), from 12 to 18 years of age (M = 16.29, SD = 1.66). Participants answered the Athlete Burnout Questionnaire, The Scale of the Social Support Perceived by Athletes, the Passion Scale and the Positivity Scale. The results of structural equation modeling showed a good adjustment model (χ2 = 889.213; df = 274; χ2/df = 3.245; p ˂ 0.01; CFI = 0.93; TLI = 0.91; IFI = 0.94; NFI = 0.91; RMSEA = 0.07). The harmonious passion presented direct and indirect effects on the burnout, being the perceived social support the mediator variable of the indirect effect. The positivity resulted positive predictor from the social support (ß = 0.714, p ˂ 0.001) and social support predicted the burnout (ß = -0.270, p ˂ 0.005). The obsessive passion had a direct effect over burnout (ß = 0.627, p ˂ 0.001). Developing negative commitments to sports could be an indicator of a greater risk of experiencing individual conflicts that lead to sports burnout.

RESUMO

The Austral and Neotropical America (ANA) section of the Society for Conservation Biology includes a vast territory with some of the largest relatively pristine ecosystems in the world. With more than 573 million people, the economic growth of the region still depends strongly on natural resource exploitation and still has high rates of environmental degradation and biodiversity loss. A survey among the ANA section membership, with more than 700 members, including most of the section's prominent ecologists and conservationists, indicates that lack of capacity building for conservation, corruption, and threats such as deforestation and illegal trade of species, are among the most urgent problems that need to be addressed to improve conservation in the region. There are, however, strong universities and ecology groups taking the lead in environmental research and conservation, a most important issue to enhance the ability of the region to solve conservation and development conflicts.

RESUMO

INTRODUCTION: Introduction: recent research shows that people with high levels of self-efficacy for a healthy diet can control their weight. The Dieting Self-Efficacy Scale (DIET-SE) scale is a complete instrument that measures self-efficacy for a healthy diet, however, there are no Spanish versions for the Mexican population. Objective: the purpose of this study is to analyze the psychometric properties of the Mexican version of DIET-SE. Method: the sample consisted of 807 Mexican university students, of both sexes and aged between 17 and 48 years (M = 20.65, SD = 3.16). The parallel back-translation methodology was used to translate the DIET-SE scale into Spanish. In addition to the descriptive analysis and the Pearson correlation, the Cronbach alpha coefficient was used to measure the internal consistency and other indices were used for the factorial model. Results: the results of the CFA using the maximum likelihood estimation found good evidence for the construct validity (χ2 = 175.68; gl = 35 [77-42]; χ2/gl = 5.02, p < 0.01; TLI = 0.92, IFI = 0.96, CFI = 0.95 y RMSEA = 0.07). The factorial loads of the eleven items showed acceptable values. The results in the correlation analysis between the DIET-SE and psychological well-being indicators can be considered as a favorable proof of the discriminant validity. In terms of reliability, acceptable results were found in internal consistency. Conclusion: the DIET-SE is a valid and reliable scale to evaluate the self-efficacy to maintain a diet in Mexican university students.


INTRODUCCIÓN: Introducción: investigaciones recientes demuestran que las personas con altos niveles en autoeficacia para llevar una dieta saludable pueden controlar su peso. La escala Dieting Self-Efficacy Scale (DIET-SE) es un instrumento completo que mide la autoeficacia para llevar una dieta saludable, sin embargo, no existen versiones en español para población mexicana. Objetivo: el propósito del presente estudio es analizar las propiedades psicométricas de la versión mexicana del DIET-SE. Método: la muestra estuvo conformada por 807 estudiantes universitarios mexicanos, de ambos sexos y con edades comprendidas entre los 17 y los 48 años (M = 20,65, DT = 3,16). Para la traducción al castellano de la escala DIET-SE, se siguió la metodología parallel back- translation. Además del análisis descriptivo y la correlación de Pearson, se utilizó el coeficiente alfa de Cronbach para el estudio de la consistencia interna y para el ajuste del modelo se utilizaron varios índices. Resultados: los resultados del AFC por el método de máxima verosimilitud encontraron suficiente evidencia para la validez de constructo (χ2 = 175,68;gl = 35 [77-42]; χ2/gl = 5,02, p < 0,01; TLI = 0,92, IFI = 0,96, CFI = 0,95 y RMSEA = 0,07). Las cargas factoriales de los once ítems mostraron valores aceptables. Los resultados en el análisis de correlación entre la DIET-SE y los indicadores de bienestar psicológico pueden considerarse como prueba favorable de la validez discriminante. En cuanto a la fiabilidad, se encontraron resultados aceptables en consistencia interna. Conclusión: la DIET-SE es una escala válida y fiable para evaluar la autoeficacia para mantener una dieta en estudiantes universitarios mexicanos.

RESUMO

INTRODUCTION: empirical research shows that perceived self-efficacy is an important variable in maintaining and reducing weight. There are available instruments to measure perceived self-efficacy and its relation to obesity, but in Mexico it is still insufficient. OBJECTIVE: the purpose of the current research is to analyze the psychometric properties of the Mexican version of the self-efficacy inventory for weight control (SEI-WC) in university students in the health area. METHODS: participants in this study were 872 university students from the School of Health Sciences, aged between 17 and 47 (20.07 ± 2.61) years. Bartlett's sphericity test was performed to evaluate the relevance of the factor analysis. The principal component analysis with Varimax rotation was used to evaluate the adjustment of the scores on each factor. RESULTS: internal consistency (Cronbach's alpha) shows adequate psychometric properties for the three final factors: 0.856 for the factor "feeding style and externality", 0.85 for "programmed physical activity" and 0.671 for "daily physical activity". CONCLUSION: the findings of this study show that the SEI-WC is a reliable and valid instrument to measure the level of self-efficacy for weight control in Mexican university students in the health area.

RESUMO

Metastatic Crohn's disease (MCD) is a rare cutaneous manifestation of Crohn's disease (CD). The simultaneous involvement of the vulva and oral region is uncommon in clinical presentations of MCD. We present the case of a middle-aged woman with a family history of autoimmunity who initially presented with oral and vulvoperineal involvement. Initially, Behçet's disease was ruled out, but histopathological studies of the vulva revealed findings compatible with MCD. The patient had no gastrointestinal symptoms, and fecal calprotectin levels were normal. Upper and lower endoscopic examinations and capsule endoscopy of the small intestine (SI) did not reveal any significant findings. Treatment with anti-tumor necrosis factor (anti-TNF) agents was initiated but resulted in paradoxical psoriasis with adalimumab and infliximab. Cyclosporine was also used, but the patient experienced intolerable tachycardia. After 18 months, the patient developed episcleritis and experienced diarrhea accompanied by cramp-like abdominal pain. Repeat upper and lower endoscopic examinations showed normal results, while capsule endoscopy of the SI revealed CD enteritis. The patient was diagnosed with CD of the small intestine, along with extraintestinal manifestations of vulvoperineal MCD, oral involvement, and episcleritis. Management with azathioprine and ustekinumab was initiated, resulting in significant clinical improvement. MCD poses a diagnostic challenge due to its unusual manifestations. It may present without gastrointestinal tract involvement, mimicking other conditions. Therefore, timely diagnosis and the selection of the most appropriate therapeutic strategy are crucial.


La enfermedad de Crohn metastásica (ECM) es una entidad rara, es una manifestación cutánea en enfermedad Crohn (EC), y en su presentación clínica es inusual el compromiso vulvar y oral de modo concomitante. Se describe el caso de una mujer de edad media que tiene historia familiar de autoinmunidad, presenta inicialmente compromiso oral y vulvoperineal. En su abordaje inicial se descartó enfermedad de Behçet, pero los estudios histopatológicos a nivel vulvar tuvieron hallazgos compatibles para ECM. Hubo ausencia de síntomas gastrointestinales y sus niveles de calprotectina fecal eran normales. Los estudios endoscópicos altos y bajos, y la cápsula endoscópica del intestino delgado (ID) no tuvieron hallazgos relevantes. Se inició el tratamiento con antifactor de necrosis tumoral (anti-TNF) y presentó una psoriasis paradójica con adalimumab e infliximab. También se utilizó ciclosporina y presentó una taquicardia intolerable. 18 meses después de estos síntomas tuvo epiescleritis e inició con diarrea asociada a dolor abdominal tipo cólico, por lo que se repitieron los estudios endoscópicos altos y bajos, que resultaron normales, y cápsula endoscópica de ID mostró una enteritis por EC. Se consideró EC de ID con manifestaciones extraintestinales y con ECM vulvoperineal, compromiso oral y epiescleritis. Se requirió manejo con azatioprina y ustekinumab, con una mejoría clínica significativa. La ECM es un reto diagnóstico, pues es una manifestación inusual; en su debut puede haber ausencia de compromiso en el tracto gastrointestinal y también simular otras entidades. Debe buscarse lograr el diagnóstico oportuno y la estrategia terapéutica más segura.

RESUMO

The San Martin titi monkey (Plecturocebus oenanthe) is endemic to a small area of northern Peru and is considered Critically Endangered on the IUCN due to massive habitat loss. Between 1994 and 2005 small scale reforestation efforts in the 23.5 ha area of Pucunucho have led to the recuperation of habitat from an area of pasture and crop lands. The first record of P. oenanthe re-establishment in the area is from 2010, although re-establishment probably began earlier. We carried out short population surveys using triangulation to monitor densities of P. oenanthe in Pucunucho in 2011, 2012 and 2016. We estimate the current population of P. oenanthe in this area at 27 individuals, giving population densities of 35 groups/km2 and 124 individuals/km2. The successful regeneration of habitat and natural re-population of the area by this Critically Endangered species provides evidence of successful reforestation based conservation activities for this and potentially other primate species. Although now protected as a Private Conservation Area, Pucunucho remains threatened.

RESUMO

Introducción: La hemofilia es un trastorno hemorrágico que causa dolor y daños articulares graves. Las personas con esta condición de salud suelen presentar problemas psicosociales como baja autoestima y dificultad para enfrentar la enfermedad, lo cual puede impactar negativamente en su calidad de vida relacionada a la salud (CVRS). Objetivo: Analizar el efecto predictor de la autoestima y las estrategias de afrontamiento hacia la CVRS en personas con hemofilia. Métodos: Estudio cuantitativo, no experimental, de tipo correlacional, con muestra por conveniencia, realizado en 60 participantes con hemofilia, edades comprendidas entre 15 y 67 años (media = 27,43, desviación estándar = 11,32). Se utilizaron los cuestionarios: Calidad de Vida Específica para Hemofilia, Autoestima y Afrontamiento al Dolor Crónico. Se realizaron análisis descriptivos, correlación de Pearson y análisis de regresión lineal múltiple con el método por pasos. Resultados: Se obtuvo que el nivel de CVRS fue mayormente moderado; sin embargo, se observaron niveles bajos en las dimensiones Deporte y tiempo libre y Futuro. La dimensión Éxito de la escala de autoestima correlacionó positivamente con las dimensiones Deporte y tiempo libre (r(60)= 0,59), Salud física (r(60)=0,54) y Autopercepción (r(60)=0,48) de la escala calidad de vida; además de haber mostrado un nivel alto de predicción de la calidad de vida (R 2 = 0,35, p= 0,00). Conclusiones: Se comprobó que la autoestima resulta ser una variable predictora de la CVRS de los pacientes con hemofilia. Se requiere fortalecer la autoestima y la manera de enfrentarse ante el dolor crónico en personas con este padecimiento en pro de su calidad de vida y bienestar(AU)


Introduction: Hemophilia is a bleeding disorder that causes severe pain and damage to the joints. People with this health condition often present psychosocial problems such as low self-esteem and difficulty facing their disease, which can negatively impact their health-related quality of life (HRQoL). Objective: To analyze the predictive effect of self-esteem and coping strategies towards HRQL in people with hemophilia. Methods: This was a quantitative, non-experimental, correlational study, with a convenience sample, carried out in 60 participants with hemophilia, ages between 15 and 67 years (mean = 27.43, standard deviation = 11.32). The Specific Quality of Life for Hemophilia, Self-esteem and Coping with Chronic Pain questionnaires were used. Descriptive analyzes. Pearson correlation and multiple linear regression analysis were performed with the stepwise method. Results: It was found that the level of HRQL was mostly moderate, however, low levels were observed in the Sports and free time and Future dimensions. The Success dimension of the self-esteem scale positively correlated with the Sports and free time dimensions (r(60) = 0.59). Physical health (r(60) = 0.54) and Self-perception (r(60) = 0.48) of the quality of life scale, in addition to having shown a high level of prediction of quality of life (R2 = 0.35, p = 0.00). Conclusions: It was found that self-esteem turns out to be a predictor variable of HRQL in patients with hemophilia. It is necessary to strengthen self-esteem and the way of coping with chronic pain in people with this condition in favor of their quality of life and well-being(AU)

RESUMO

The aim of this study was to identify trends in the incidence of lung cancer in the Leon Healthcare Area. All cases of cancer among residents of the Leon healthcare catchment area listed in the hospital-based tumor registry of the Centro Asistencial Universitario de Leon (CAULE) between 1996 and 2010 were included. Gross incidence rates over 3-year intervals were calculated and adjusted for the worldwide and European populations. A total of 2,491 cases were included. In men, incidence adjusted for the European population rose from 40.1 new cases per 100,000 population (1996-1998) to 61.8 (2005-2007), and then fell to 54.6 (2008-2010). In women, incidence tripled from 3.0 (1996-1998) to 9.2 new cases per 100,000 (2008-2010). Although lung cancer is an avoidable disease, it is a serious problem in the Leon Healthcare Area. Of particular concern is the rising incidence among women.

RESUMO

The Utrecht Work Engagement Scale (UWES) is an instrument designed by Schaufeli y Bakker (2003) to measure engagement in the work context. The purpose of the present study was to adapt the UWES to the sports context. The sample consists of 240 national third division Spanish football players between the ages of 15 and 38. The UWES factor structure has been analyzed through exploratory and confirmatory factor analyses. The results reveal a three-factor structure of the scale (vigor, absorption and dedication) and also an adequate internal consistency in all cases. Finally the results show preliminary support for the validity of the construct as sport burnout is negatively related to the three engagement characteristics. These findings provide preliminary evidence for the benefits of using the UWES in the sports context.


La Escala de Compromiso en el Trabajo de Utrecht [(Utrecht Work Engagement Scale (UWES)] (2003) mide el compromiso en el contexto laboral. El propósito de este estudio fue adaptar la UWES al contexto del deporte. La muestra estubo compuesta por 240 juegadores de futbol españoles de tercera división, con edades entre 15 y 38 años. La estructura factorial de la UWES ha sido analizada mediante análisis factorial exploratorio y confirmatorio. El resultado revela una estructura de tres factores (vigor, absorción y dedicación) y también una adecuada consistencia interna en todos los casos. Finalmente el resultado mostró preliminarmente soporte para la validez de constructo como el burnout en el deporte está negativamente relacionado con tres características del compromiso. Estos hallazgos dan una evidencia preliminar para el beneficio de usar la UWES en el contexto del deporte.

RESUMO

La epilepsia es una enfermedad crónica frecuente en niños, poco conocida y habitualmente estigmatizada. En los países en desarrollo es más frecuente en las áreas rurales y generalmente es de causa secundaria. Objetivos: Determinar el nivel de conocimiento y creencias sobre epilepsia en los padres de familia usuarios habituales del Centro de Salud de Peralvillo û Huaral. Materiales y Métodos: Estudio descriptivo y transversal. Se aplicó un instrumento anónimo validado para determinar el nivel de conocimiento y creencias en una población de padres de familia del Asentamiento Humano Peralvillo Huaral, Lima. Resultados: Se realizaron 104 entrevistas. El conocimiento nulo se encontró en el 44,2%. El 31% tuvo por lo menos una creencia siendo la más frecuente que el paciente en estado de crisis puede volverse agresivo. Se encontró una relación directa entre grado de instrucción y el nivel de conocimiento, no se observó asociación entre las demás variables sociodemográficas y el conocimiento. Conclusiones: En la población investigada se encontró bajo nivel de conocimiento sobre epilepsia en niños. El grado de instrucción, a diferencia de las demás características sociodemográficas, mostró una relación directa con nivel de conocimiento. Fueron frecuentes las creencias.


Epilepsy is a chronic common disease in children, little known and commonly stigmatized. In developing countries is more common in rural areas and generally by secondary cause. Objectives: To determine the level of knowledge and beliefs about epilepsy in parents of the Health Micro-Net of Peralvillo-Huaral. Materials and Methods: Descriptive transversal study. A validated anonymous quiz was applied to a group of parents of Peralvillo-Huaral health center, to determinate knowledge and beliefs level about epilepsy in children. Results: One hundred and four interviews were performed, 44.2% (46) had no knowledge. 31% had at least one belief; the most frequent was to consider that an epileptic patient can be aggressive during a seizure. We found a direct relationship between level of education and the level of knowledge, there was no association between socio-demographic and other knowledge. Conclusions: A low knowledge level about epilepsy in children was found in the studied population. Level of education, unlike the other social demographic characters, showed a direct relationship with knowledge level. Beliefs were frequent.

RESUMO

El estudio presenta una evaluación de la efectividad de la distribución colectiva de drogas antipalúdicas en una región predominantemente agrícola de la costa del estado de Chiapas, cercana a la frontera con Guatemala, que en 1979 y 1980 presentó una incidencia de paludismo de 2,848 y 3,648 casos, respectivamente. En esta área la enfermedad es ocasionada principalmente por Plasmodium vivax, aunque Plasmodum falciparum representa 22% del total. El principal vector es el Anopheles albimanus, resistente a una amplia gama de insecticidas. Dada esta situación que obliga a considerar alternativas más efectivas para el control de la enfermedad, un grupode investigadores de la Dirección de Lucha contra el Paludismo y de la Organización Panamericana de la Salud hicieron este estudio evaluativo sobre los resultados de tres dosis de cloroquina y primaquina que se intentaba dar a la mayoría de los habitantes de sesenta localidades con alta endemicidad y con una población de 18,700 habitantes. La comparación se basó en los cambios observados en el patrón de la incidencia para la zona y en el seguimiento de 54 personas diagnosticadas com paludismo durante la primera fase del trtamiento, a quienes se les hicieron exámenes de gota gruesa y cuestionamineto directo. Entre 7 y 10 meses, de los54 casos 10 fueron diagnosticados parasitoscópicamente, 35 fueron negativos y 9 casos fueron perdidos del seguimiento. Se encontró que la tasa de incidencia fue menor que en los años anteriores, mientras que se mantuvo relativamente constante en las comunidades no tratadas. Por esta razones, los autores sugieren que esta forma de tratamiento puede ser un medio efectivo para el control del paludismo en las áreas endémicas de México; aunque es necesario hacer otros estudios evaluativos para contrastar estos resultados
