Background: According to the 'Simple View of Reading' (Hoover and Gough 1990), individual differences in reading comprehension are accounted for by decoding skills and listening comprehension, each of which makes a unique and specific contribution. Aims: The current research was aimed at testing the Simple View of Reading in individuals with Down's syndrome and comparing their profiles with typically developing first graders. Methods & Procedures: Listening comprehension and the ability to read both words and non-words was compared in two groups with the same level of reading comprehension: 23 individuals with Down's syndrome aged between 11 years 3 months and 18 years 2 months and 23 first-grade typically developing children aged between 6 years 2 months and 7 years 4 months. Outcomes & Results: The results indicate that at the same level of reading comprehension, individuals with Down's syndrome have less developed listening comprehension and more advanced word recognition than typically developing first graders. A comparison of the profiles of the two groups revealed that reading comprehension level was predicted by listening comprehension in both groups of participants and by word-reading skills only in typically developing children. Conclusions & Implications: The Simple View of Reading model is confirmed for individuals with Down's syndrome, although they do not show the reading profile of typically developing first graders; rather, they show an atypical profile similar to that of 'poor comprehenders' (Cain and Oakhill 2006). The crucial role of listening comprehension in Down's syndrome is also discussed with reference to the educational implications. [ABSTRACT FROM AUTHOR]

In patients with heart failure and wide QRS complex, cardiac resynchronization therapy (CRT) is associated with improvement of symptoms and cardiac function. This study examined the effects of a 3-month period of CRT on left ventricular (LV) and right ventricular (RV) ejection fraction (EF) and on LV volumes, both at rest and during exercise. A CRT system was implanted in 15 patients with severe heart failure and wide QRS. Before implant and 3 months later, all patients underwent assessment of cardiac performance with equilibrium Tc(99) radionuclide angiography with imaging in the best septal left anterior oblique view. Exercise was performed on a bicycle ergometer. At 3 months, a significant improvement in New York Heart Association functional class was observed, and radionuclide angiography showed a significant decrease in LV volumes and a significant increase in LVEF at rest, as well as a significant increase in LVEF during exercise. The remodeling processes associated with CRT did not appear to include RV function, since RVEF did not improve, and changes in RVEF did not correlate with changes in LVEF, neither at rest nor during exercise.

Splenectomy is a time-honoured well established approach for patients with steroid-resistant immune thrombocytopenia (ITP). However, due to the more recent availability of therapeutic options alternative to splenectomy, such as rituximab and agonists of the thrombopoietin-receptor, the choice of second-line therapy is challenging. Platelet kinetics has been widely used to predict response to splenectomy. We describe the outcome of 70 chronic ITP patients who performed a platelet kinetic study after failure of front-line corticosteroids and subsequently underwent open splenectomy. After a median follow-up from surgery of 20 years, 62 (88.5%) patients responded to splenectomy and 9 patients (13%) relapsed. Achieving a complete response (CR) significantly predicted a higher probability long-term stable response. The pattern of platelet sequestration was predominantly splenic in 52 patients (74%), predominantly hepatic in 12 patients (17%), and diffuse in 6 (9%). Patients with nonsplenic (diffuse and hepatic) sequestration showed significantly lower overall responses compared to patients with splenic captation (P = 0.002). A nonsplenic sequestration significantly correlated with lower CR rate and, among CR patients, predicted an increased risk of relapse. Also, the probability of stable responses in nonsplenic uptake patients was substantially lower than in patients with splenic uptake (85% vs. 50%, P = 0.0083). Platelet life span and platelet turnover did not correlate with response and relapse rate. Overall, splenic sequestration was able to predict not only a better quality, but also a higher durability of the responses. However, it should be enphasized that the response rate and duration of response even in patients with nonsplenic uptake were similar or even superior to those reported in patients treated with rituximab as first option., (© 2014 Wiley Periodicals, Inc.)
