Simple view of reading in Spanish: A longitudinal study / Concepción simple de la lectura en español: un estudio longitudinal

Objectives: Test the validity of the Simple View of Reading (Gough & Tunmer, 1986) in Spanish and analyze the contributions of decoding and linguistic abilities to reading comprehension. Method: This longitudinal study assessed a sample of 71 Spanish speaking children at Grade 1 and Grade 3. At each time point, a battery of tests assessed children's linguistic abilities, decoding and reading comprehension. The authors used the classic model of SVR: model 0 (pseudoword accuracy reading and listening comprehension) and a complex model: Model 1 (linguistic abilities and decoding). Results: Results of regression analyses showed that the original model of the SVR, explained little variance of reading comprehension in Spanish in comparison with the results obtained in English. However, a complex model explained 51% and 55% of the variance of reading comprehension in first and third grade respectively. The unique contribution of linguistic abilities increased from 27% in first grade to 43% in third grade and the contribution of decoding decreased from 24% in first grade to 2% in third grade. Conclusions: The results are explained in terms of the transparent nature of Spanish orthography and educational implications are discussed.(AU)

ObjetivosEvaluar la validez de la concepción simple de la lectura (Gough y Tunmer, 1986) en español y analizar la contribución de la decodificación y las habilidades lingüísticas a la comprensión lectora. Método: Se trata de un estudio longitudinal en el que se evaluó a 71 estudiantes hispanohablantes en 2 fases: en primer y en tercer curso de primaria. A todos ellos se les aplicó una serie de pruebas para evaluar las habilidades lingüísticas, la decodificación y la comprensión lectora en cada una de las fases. Los autores utilizaron el modelo original de la concepción simple de la lectura: modelo 0 (precisión en la lectura de seudopalabras y comprensión oral) y un modelo más abierto: modelo 1 (habilidades lingüísticas y decodificación). Resultados: Tras un análisis de regresión, se encontró que el modelo original de la concepción simple de la lectura explicó una varianza muy pequeña de la comprensión lectora en español en comparación los resultados obtenidos en inglés. Sin embargo, un modelo más abierto logró explicar el 51 y el 55% de la varianza de la comprensión lectora en el primer y el tercer curso de primaria, respectivamente. La contribución única de las habilidades lingüísticas se incrementó de un 27% en el primer curso a un 43% en el tercer curso y el aporte de la decodificación disminuyó de un 24% alcanzado en el primer curso a un 2% en el tercer curso. Conclusiones: Los resultados se explican en términos de la transparencia del sistema ortográfico del español. Los hallazgos tienen importantes implicaciones que son discutidas.(AU)

NT-proBNP in Myocarditis after a Scorpion Sting Envenomation.

OBJECTIVE: This study was to evaluate the levels of NT-proBNP in patients with myocarditis which occurred after a scorpion sting envenomation. MATERIAL AND METHODS: A total of 30 patients with scorpion sting envenomation and 21 patients with heart failure which was caused by cardiomyopathy, were prospectively studied. The data included the patient demographics, clinical features, echocardiography and the NT-proBNP levels. RESULTS: An echocardiographic evidence of myocarditis with a left ventricular ejection fraction of less than 50%, was found in 22 patients. In all the 22 patients, NT-proBNP was significantly elevated. The NT-proBNP levels were very high in the patients with severe LV dysfunction. However, it was in the normal range in the patients without an evidence of myocarditis. The elevated NT-proBNP levels were correlated with the LV dysfunction and myocarditis. When they were compared with the patients with heart failure which was caused by cardiomyopathy, the NTproBNP levels were found to be significantly more elevated in scorpion sting myocarditis. CONCLUSIONS: The NT-proBNP levels were significantly elevated in myocarditis which occurred after a scorpion sting envenomation.

Evaluation of internal dose to members of the public at the Kaiga site, India, due to the ingestion of primordial radionuclide 40K.

Four 220 MWe pressurised heavy water reactors are under operation at Kaiga in the state of Karnataka in India. Environmental radiological survey of the surrounding areas of the Kaiga site is carried out by Bhabha Atomic Research Centre, Mumbai. The estimated dose to the members of the public due to ingestion of radioactive isotope of potassium, a natural radionuclide, in the surroundings of the Kaiga site is 136 µSv (13.6 mrem) per year. The value indicates that the dose to the public due to operation of the nuclear reactors in Kaiga is insignificant in comparison with the dose due to unavoidable natural radioactivity.

Echocardiography guided therapy for myocarditis after scorpion sting envenomation.

OBJECTIVE: This study was to evaluate echocardiographic findings and its usefulness in clinical management of patients with scorpion sting envenomation. MATERIAL AND METHODS: A total of 84 consecutive patients were prospectively studied. The data included demographics, at the time of presentation to the hospital, the clinical features, echocardiographic findings, admission to intensive care unit, use of inotropic medication, time to discharge, and mortality. RESULTS: Out of 84 patients studied 60 patients (71.4%) had echocardiographic evidence of myocarditis (LVEF <50%). Majority of patients had LVEF <40% (50 patients, 83.3%). Severe LV dysfunction (LVEF <30%) was noted in 20 patients (33.3%). No patient had significant valvular regurgitation. RV dysfunction was noted in half of the patients who had LV dysfunction. RV dysfunction was not seen in isolation. Twenty four patients without evidence of myocarditis on echocardiography were observed in general wards and were discharged in 24 to 48 hours of admission. Ten patients with mild LV dysfunction (LVEF 50-40%) and 20 patients with moderate LV dysfunction were observed in high dependency units with regular monitoring for 24 to 48 hours. Only 3 patients were put on inotropics support and others could be discharged in 72 to 96 hours. All the patients with severe LV dysfunction and moderate LV dysfunction with significant RV dysfunction were admitted in intensive care unit irrespective of symptoms (Total 30 patients). These patients were put on inotropics support. Among severe LV dysfunction group, 4 patients required ventilator support and 2 (2.3%) patients died with refractory shock and multi-organ failure. Tachycardia, muffled and or gallop heart sounds and hypertension didn't predict presence of LV dysfunction. Persistent hypotension requiring inotropics support was a marker of severe LV dysfunction. CONCLUSION: Echocardiography is a useful tool in emergency to assess LV function in patients with scorpion sting envenomation. It can guide therapy by identifying patients with severe LV dysfunction.

Elevated Cardiac Troponin (cTnI) Levels Correlate with the Clinical and Echocardiographic Evidences of Severe Myocarditis in Scorpion Sting Envenomation.

OBJECTIVE: This study was to evaluate the predictive value of the cardiac troponins in scorpion sting myocarditis at a tertiary care hospital in Raichur, (Karnataka state) India. METHODS: A total of 84 consecutive patients were prospectively studied. The data included the demographics, the time of presentation to the hospital, the clinical features, the cardiac troponin levels and the echocardiographic findings. RESULTS: 12 patients with only local symptoms had troponin levels of less than 0.01µg/L. 12 patients with local and systemic symptoms without an echocardiac evidence of myocarditis had troponin values of 0.01 to 0.11 µg/L. 60 patients with an echocardiographic evidence of myocarditis had troponin levels of above 0.11 µg/L. 6 patients with severe myocarditis who required ventilator support or which led to death had troponin values which were higher than 10 µg/L. CONCLUSIONS: High cardiac troponin levels predict myocarditis in scorpion sting envenomation and they can be a useful tool in guiding the therapy early.

A case of acute Fitz-Hugh-Curtis syndrome in a young woman with purulent peritonitis and acute purulent appendicitis and oophoritis is presented. Open emergency appendectomy was performed and peritoneal pus was drained. Neisseria gonorrhoeae was cultured from the peritoneal pus. The hepatic enzymes were found to be raised. The patient was successfully managed and is asymptomatic after three months follow-up. To our knowledge, this is the first case of Fitz-Hugh-Curtis syndrome reported from Kuwait.

Transfer coefficient of 137Cs from feed to cow milk in tropical region Kaiga, India.

In the transport model for the prediction of the concentration of (137)Cs in milk, the transfer coefficient from feed to milk, F(m), is an important parameter. Site-specific transfer coefficient from feed to cow's milk, for (137)Cs in the Kaiga environment, a nuclear power station site in India, determined over a period of 10 y is presented in this paper. The value is determined from (137)Cs concentration in milk and grass samples of the Kaiga region and the result ranged from 6.43E-03 to 1.09E-02 d l(-1) with a geometric mean value of 8.0E-03 d l(-1). The result is compared with that for (40)K, determined concurrently at the same region and ranged from 3.06E-03 to 3.48E-03 d l(-1) with a geometric mean value of 3.26E-03 d l(-1). This parameter is quite useful in decision-making for implementing countermeasures during a large area contamination with (137)Cs in tropical areas like Kaiga.

Soil to leaf transfer factor for the radionuclides ²²6Ra, 4°K, ¹³7Cs and 9°Sr at Kaiga region, India.

Transfer factors are the most important parameters required for mathematical modeling used for environmental impact assessment of radioactive contamination in the environment. In this paper soil to leaf transfer factor for the radionuclides 4°K, ²²6Ra, ¹³7Cs and 9°Sr is estimated for Kaiga region in Karnataka state, India. Among the plants in which study is carried out, ²²6Ra, 4°K, ¹³7Cs and 9°Sr activity in leaves of herbaceous plants is higher than that of tree leaves. Soil to leaf transfer factor for ²²6Ra, 4°K, ¹³7Cs and 9°Sr was found to be in the range of 0.03-0.65, 0.32-8.04, 0.05-3.03 and 0.42-2.67 respectively.

Outcome of head injury patients undergoing surgical management: a tertiary level experience.

BACKGROUND: Head injury is the major cause of death in a neurosurgical patient. OBJECTIVE: To find the outcome, and treatment modality affecting the outcome in patients with head injury. METHODS: Nine hundred eighty seven patients presenting to National Institute of Neurological and Allied Sciences, Kathmandu, with head injury from September 2009 to October 2010 were included in the study. Patients were categorized according to post resuscitation Glasgow Coma Score. Outcome was assessed at discharge using Glasgow Outcome Score and analyzed for any correlation with modality of treatment and severity of injury. RESULTS: Among 987 patients with head injury,152 (15.4%) had severe, 126 (12.8%) had moderate and 709 (71.8%) had mild head injuries. Three hundred twelve (31.6%) patients required definitive and supportive surgical intervention. One hundred eighty two required cranial surgical intervention. Overall mortality was 10% (99), 137 patients (13.9%) had unfavorable outcome and 850 (86.1%) had favorable Glasgow Outcome Score of 4 and 5. Mortality was 53.2%, 9.5% and 0.8% in severe, moderate and mild head injury group respectively. Mortality rate was significantly higher (64.6%) in severe head injury group managed conservatively than those in same group treated with supportive and definite surgical intervention (44.8%) (p=0.016). CONCLUSION: Mortality in head injury patients depend upon severity of injury. Mortality in severe head injury group can be reduced by supportive and definite surgical intervention.
