METHODS: Through stratified random sampling, 1469 students, aged 18-19 years, were enrolled. Participants whose score achieved the aggressive evaluation standard were selected and then 60 participants were randomly divided into 2 groups: G-IPT and control. The participants in the G-IPT group received 16 sessions of treatment, whereas the participants in the control group did not receive any intervention. All participants completed the assessment three times: before, after, and tracking.
RESULTS: The results showed that the total score and the scores of all subscales of aggression dropped significantly (P
METHODS: During 2012 to 2017, suspected thalassemia people were detected for common α- and β-thalassemia mutations by gap-Polymerase Chain Reaction (PCR) and reverse dot blot (RDB) analysis in Peking Union Medical College Hospital. One thousand and fifty-nine people with thalassemia mutations were analyzed retrospectively. We picked mutated individuals who originally came from northern areas, and conducted telephone follow-up survey in order to collect their ancestral information. Besides, we used "thalassemia", "mutation", and "Southeast Asian countries" as keywords to search the relevant studies in PubMed and Embase databases.
RESULTS: All carriers included in our study were resided in northern China. Among them, 17.3% were native northerners and 82.7% were immigrants from southern China. Although substantial difference was found in α- and β-thalassemia ratio and detailed spectrum of α- and β-globin mutation spectrum between our data and data obtained from a previous meta-analysis literature focused on southern China, the most common gene mutations were the same. Similar β-thalassemia mutation spectrum was found among Thai, Malaysian Chinese, and Guangdong people, however, no other similarities in gene profile were found between Chinese and other ethnic groups in Southeast Asia.
CONCLUSION: Chinese people in different areas had similar gene mutation, whereas they had significantly different mutation spectrums from other ethnic groups in Southeast Asia.
AIM: To evaluate the preferred diagnosis and management practices of BE among Asian endoscopists.
METHODS: Endoscopists from across Asia were invited to participate in an online questionnaire comprising eleven questions regarding diagnosis, surveillance and management of BE.
RESULTS: Five hundred sixty-nine of 1016 (56.0%) respondents completed the survey, with most respondents from Japan (n = 310, 54.5%) and China (n = 129, 22.7%). Overall, the preferred endoscopic landmark of the esophagogastric junction was squamo-columnar junction (42.0%). Distal palisade vessels was preferred in Japan (59.0% vs 10.0%, P < 0.001) while outside Japan, squamo-columnar junction was preferred (59.5% vs 27.4%, P < 0.001). Only 16.3% of respondents used Prague C and M criteria all the time. It was never used by 46.1% of Japanese, whereas 84.2% outside Japan, endoscopists used it to varying extents (P < 0.001). Most Asian endoscopists (70.8%) would survey long-segment BE without dysplasia every two years. Adherence to Seattle protocol was poor with only 6.3% always performing it. 73.2% of Japanese never did it, compared to 19.3% outside Japan (P < 0.001). The most preferred (74.0%) treatment of non-dysplastic BE was proton pump inhibitor only when the patient was symptomatic or had esophagitis. For BE with low-grade dysplasia, 6-monthly surveillance was preferred in 61.9% within Japan vs 47.9% outside Japan (P < 0.001).
CONCLUSION: Diagnosis and management of BE varied within Asia, with stark contrast between Japan and outside Japan. Most Asian endoscopists chose squamo-columnar junction to be the landmark for esophagogastric junction, which is incorrect. Most also did not consistently use Prague criteria, and Seattle protocol. Lack of standardization, education and research are possible reasons.
Methods: We retrospectively analyzed 7329 colonoscopy procedures performed by 12 endoscopists between January 2012 and February 2014. The PDR, actual ADR, and estimated ADR of the entire, proximal, and distal colon, and within each colonic segment, in two patient age groups: <50 and ≥50 years, were calculated for each endoscopist.
Results: The overall polyp and adenoma prevalence rates were 19.1 and 9.3%, respectively. The average age of adenoma-positive patients was significantly higher than that of adenoma-negative patients (54 ± 12.6 years vs 42.9 ± 13.2 years, respectively). A total of 1739 polyps were removed, among which 826 were adenomas. More adenomatous polyps were found in the proximal colon (60.4%, 341/565) than in the distal colon (40.9%, 472/1154). Overall, both actual and estimated ADR correlated strongly at the entire colon level and within most colonic segments, except for the cecum and rectum. In both age groups, these parameters correlated strongly within the traverse colon and descending colon.
Conclusion: Caution should be exercised when predicting ADR within the sigmoid colon and rectum.
METHODS: Surgeons in the APFCP completed an Institutional Review Board-approved anonymous e-survey and/or printed letters (for China) containing 19 questions regarding nonsurgical close observation in patients who achieved clinical complete response (cCR) to neoadjuvant chemoradiotherapy (nCRT).
RESULTS: Of the 417 responses, 80.8% (n = 337) supported the W&W approach and 65.5% (n = 273) treated patients who achieved cCR after nCRT. Importantly, 78% of participants (n = 326) preferred a selective W&W approach in patients with old age and medical comorbidities who achieved cCR. In regard to restaging methods after nCRT, the majority of respondents based their decision to use W&W on a combination of magnetic resonance imaging results (94.5%, n = 394) with other test results. For interval between nCRT completion and tumor response assessment, most participants used 8 weeks (n = 154, 36.9%), followed by 6 weeks (n = 127, 30.5%) and 4 weeks (n = 102, 24.5%). In response to the question of how often responders followed-up after W&W, the predominant period was every 3 months (209 participants, 50.1%) followed by every 2 months (75 participants, 18.0%). If local regrowth was found during follow-up, most participants (79.9%, n = 333) recommended radical surgery as an initial management.
CONCLUSION: The W&W approach is supported by 80% of Asia-Pacific surgeons and is practiced at 65%, although heterogeneous hospital or society protocols are also observed. These results inform oncologists of future clinical study participation.
