Objective: Although a transjugular intrahepatic portosystemic shunt (TIPS) is commonly placed to manage isolated gastric varices, balloon-occluded retrograde transvenous obliteration (BRTO) has also been used. We compare the long-term outcomes from these procedures based on our institutional experience. Materials and Methods: We conducted a retrospective review of patients with isolated gastric varices who underwent either TIPS with a covered stent or BRTO between January 2000 and July 2013. We identified 52 consecutive patients, 27 who had received TIPS with a covered stent and 25 who had received BRTO. We compared procedural complications, re-bleeding rates, and clinical outcomes between the two groups. Results: There were no significant differences in procedural complications between patients who underwent TIPS (7%) and those who underwent BRTO (12%) (p = 0.57). There were also no statistically significant differences in re-bleeding rates from gastric varices between the two groups (TIPS, 7% [2/27]; BRTO, 8% [2/25]; p = 0.94) or in developing new ascites following either procedure (TIPS, 4%; BRTO, 4%; p = 0.96); significantly more patients who underwent TIPS developed hepatic encephalopathy (22%) than did those who underwent BRTO (0%, p = 0.01). There was no statistically significant difference in mean survival between the two groups (TIPS, 30 months; BRTO, 24 months; p = 0.16); median survival for the patients who received TIPS was 16.6 months, and for those who underwent BRTO, it was 26.6 months. Conclusion: BRTO is an effective method of treating isolated gastric varices with similar outcomes and complication rates to those of TIPS with a covered stent but with a lower rate of hepatic encephalopathy.

Decomposing achievement gaps among OECD countries
Liang Zhang,Kristen A. Lee 서울대학교 교육연구소 2011 Asia Pacific Education Review Vol.12 No.3
In this study, we use decomposition methods on PISA 2006 data to compare student academic performance across OECD countries. We first establish an empirical model to explain the variation in academic performance across individuals, and then use the Oaxaca-Blinder decomposition method to decompose the achievement gap between each of the OECD countries and the OECD average. Results indicate that the explained portion of the achievement gap varies across countries. In some countries, our empirical models are able to account for almost all the achievement gap, while unexplained country-specific effects still dominate in other countries. Finally, we use two Asian countries, Japan and Korea, to demonstrate how to identify major factors that have contributed to the observed achievement gap across countries.

Screening Colonoscopy among Uninsured and Underinsured Urban Minorities
( Tyson H Collazo ),( Lina Jandorf ),( Linda Thelemaque ),( Kristen Lee ),( Steven H Itzkowitz ) 대한소화기학회 2015 Gut and Liver Vol.9 No.4
Background/Aims: Uninsured individuals have lower rates of screening colonoscopy (SC), and little is known regarding the pathology results obtained when they undergo colonoscopies. Since 2004, we have participated in a program that offers SC to uninsured New Yorkers; herein, we report our findings. Methods: Uninsured, average-risk patients who were at least 50 years of age underwent SC at our institution between April 2004 and June 2011. We analyzed polyp pathology, location, size, incidence of adenomas, and incidence of adenomas with advanced pathology (AAP) with respect to ethnicity, gender, and age. Results: Out of 493 referrals, 222 patients completed the colonoscopies. Polyps were identified in 21.2% of all patients; 14% had adenomas, and 4.5% had AAP. The rates of adenomas among African-Americans, Hispanics, and Whites were 24.3%, 12.1%, and 11.6%, respectively, and the corresponding rates of AAP were 10.8%, 3.5%, and 2.3%. Differences in the polyp type, location, and AAP did not reach statistical significance with respect to ethnicity or gender. Patients aged 60 and older were found to have a higher rate of advanced adenomas compared with younger patients (8.6% vs 2.6%, p=0.047). Conclusions: Further efforts to fund screening colonoscopies for uninsured individuals will likely result in the identification of advanced lesions of the colon before they progress to colorectal cancer.

Background This rapid review systematically evaluated the effects of honeybee products compared to controls for the prevention, duration, severity, and recovery of acute viral respiratory tract infections (RTIs), including SARS-CoV-2, in adults and children. Methods Cochrane rapid review methods were applied. Four English databases plus preprint servers and trial registries were searched for randomized controlled trials (RCTs). The evidence was appraised and synthesized using RoB 2.0 and GRADE. Results 27 results were derived from 9 RCTs that included 674 adults and 781 children. In hospitalized adults with SARS-CoV-2, propolis plus usual-care compared to usual-care alone reduced the risk of shock, respiratory failure and kidney injury and duration of hospital admission. Honey was less effective than Guaifenesin for reducing cough severity at 60-minutes in adults with non-specific acute viral RTIs. Compared to coffee, honey plus coffee, and honey alone reduced the severity of post-infectious cough in adults. Honey reduced the duration of cough in children compared to placebo and salbutamol; and the global impact of nocturnal cough after one night compared to usual-care alone and pharmaceutical cough medicines. Conclusion More studies are needed to robustly assess honeybee's role in SARS-CoV-2 and non-specific viral respiratory infections. Protocol registration PROSPERO: CRD42020193847.
