The impact of blogging on Hong Kong primary school students' bilingual reading literacy

This study looked at the types of blog consulted by 1,298 Primary 4 students in Hong Kong and whether such consultation influenced performance on standardised tests of Chinese and English reading comprehension. When students were asked if they consulted Chinese and English blogs, 42% said they looked at Chinese blogs and 19% said they looked at English blogs. This difference was anticipated since Chinese is the mother tongue of most primary school students in Hong Kong and English is a second language. The themes of sites consulted were categorised into types: the Chinese blogs being able to be categorised into three types, and the English blogs into two. Boys and girls differed in their choice of Chinese and English blog topics and the strength of the students' Chinese and English reading proficiency clearly had some influence on the choice of blogs consulted. Factor analysis was used to group together types of blog and analysis of variance was applied to test differences in performance. With over half of the students saying they did not consult either Chinese or English blogs, it is unwise to draw weighty conclusions about the influence of blogging on reading standards. There was little evidence that regularly consulting the Internet was associated with high grades on either Chinese or English reading tests. Given the large number of students who said they had never consulted blogs, discussion of the analytical outcomes and conclusions are guarded but recommendations are offered.published_or_final_versio

Anti-Obesity Drugs for Obese Women Planning Pregnancy

Obesity remains an important risk factor for women planning for pregnancy because of its adverse effects on reproductive outcome. In individuals who experience difficulty in reducing significant weight with lifestyle intervention alone, the use of anti-obesity drugs can be an adjunct. Orlistat and metformin are the options currently, and their use is probably safe for women planning for pregnancy. These weight loss interventions should precede any planned conception or fertility treatment

Transient Giant R-Wave, Right Axis Deviation, and Intraventricular Conduction Delay during Exercise Treadmill Testing: A Case Report

A 53-year-old man complained of chest pain during an exercise treadmill test. Electrocardiogram revealed transient giant R-wave, right-axis deviation, intraventricular conduction delay, and ST-segment elevation in the inferolateral leads. Subsequent coronary angiography showed an 80% lesion in mid part of a nondominant left circumflex artery, whereas the other coronary arteries had mild atherosclerosis only. Percutaneous coronary intervention and stenting was performed on the left circumflex artery lesion. A follow-up exercise thallium scan 3 months later still showed an intermediate-sized, mild reversible perfusion defect in the inferior and lateral wall but the giant R-wave ECG pattern was not inducible anymore. Restudy coronary angiography showed no in-stent restenosis, but there was disease progression in the midpart of the right coronary artery. The initial electrocardiographic pattern is typical of the "giant R-wave syndrome." Severe coronary spasm superimposed on the underlying mild atherosclerotic lesion of the right coronary artery is hypothesized to be the cause of the initial event. Ad hoc direct stenting was performed on the right coronary artery lesion. The patient remained symptom-free with a normal thallium scan 9 months later.link_to_subscribed_fulltex

Anomalous origin of right coronary artery from the left coronary sinus: Incidence, characteristics, and a systematic approach for rapid diagnosis

Twenty-three patients were found to have anomalous origin of right coronary artery from the left coronary sinus (LCS) from January 2000 to October 2003. The mean age was 58.6 ± 14.3 years with male predominance (56.5%). Cardiovascular risk factors were found in 18 (78.3%) patients while coronary artery disease was seen in 13 (56.5%) patients. Among the coronary artery disease patients, the left anterior descending artery was the most commonly involved, followed by the right coronary artery and the left circumflex artery. Right coronary artery dominance was seen in 19 (82.6%) patients. The anomalous right coronary artery originates within the left coronary sinus in 17 (73.9%) patients while from the left aortic wall above the sinus in 6 (26.1%) patients only. Congenital heart disease and acquired valvular heart disease were the most common associated conditions. The author will share his experience and suggest a four-step approach of early recognition and selection of the anomalous right coronary artery ostium. Using the suggested strategy, most of the anomalous right coronary artery could be opacified with a left amplatz 1 catheter. Aortogram was needed only in 47.8% of cases.link_to_subscribed_fulltex
