Item APAGE position statements on green and sustainability in gastroenterology, hepatology, and gastrointestinal endoscopy(Blackwell Scientific Publications, 2025-01) Ang, T.L.; Hang, D.V.; Li, J.W.; Ho, J.C.L.; Sy‐Janairo, M.L; Ali, R.A.R.; Makharia, G.K.; Sundaram, S.; Chantarojanasiri, T.; Kim, H.G.; Isayama, H.; Pausawasdi, N.; Wu, K.; Syam, A.F.; Aye, T.T.; Rehman, S.; Niriella, M.A.; Jurawan, R.; Wang, L.; Leung, W.K.; Liou, J.M.; Rizan, C.; Wu, J.C.Y.; Ooi , C.J.BACKGROUND AND AIM The APAGE Position Statements aimed to provide guidance to healthcare practitioners on clinical practices aligned with climate sustainability.METHODS A taskforce convened by APAGE proposed provisional statements. Twenty-two gastroenterologists from the Asian Pacific region participated in online voting and consensus was assessed through an anonymized and iterative Delphi process.RESULTS There were five sections that addressed the rationale for climate action, the importance of adopting principles of waste management, clinical practice, gastrointestinal endoscopy, and issues related to advocacy and research. Sixteen statements achieved consensus and included the following: 1. APAGE recommends adopting prompt measures to reduce the carbon footprint of clinical practice due to the importance of climate action and its health cobenefits. 5. APAGE recommends adherence to professional clinical guidelines to optimize clinical care delivery in gastroenterology and hepatology to avoid the environmental impact of unnecessary procedures and tests. 8. APAGE recommends an emphasis on health promotion, disease prevention, and appropriate screening and surveillance, when resources are available, to reduce the environmental impact of managing more advanced diseases that require more intensive resources. 12. APAGE recommends that technological advances in endoscopic imaging and artificial intelligence, when available, be used to improve the precision of endoscopic diagnosis to reduce the risk of missed lesions and need for unnecessary biopsies. 13. APAGE recommends against the routine use of single-use endoscopes.CONCLUSION The position statements provide guidance to healthcare practitioners on clinical practices in gastroenterology, hepatology, and endoscopy that promote climate sustainability.Item 2021 Asia-Pacific Graves' Disease consortium survey of clinical practice patterns in the management of graves' disease(Humana Press, 2023) Parameswaran, R.; de Jong, M.C.; Kit, J.L.W.; Sek, K.; Nam, T.Q.; Thang, T.V.; Khue, N.T.; Aye, T.T.; Tun, P.M.; Cole, T.; Miller, J.A.; Villa, M.; Khiewvan, B.; Sirinvaravong, S.; Sin, Y.L.; Muhammad, R.; Jap, T.S.; Agrawal, A.; Rajput, R.; Fernando, R.; Sumanatilleke, M.; Suastika, K.; Shong, Y.K.; Lang, B.; Bartalena, L.; Yang, S.P.; Asian Graves Consortium Study.Aim: Although Graves' disease (GD) is common in endocrine practices worldwide, global differences in diagnosis and management remain. We sought to assess the current practices for GD in countries across Asia and the Pacific (APAC), and to compare these with previously published surveys from North America and Europe.Methods: A web-based survey on GD management was conducted on practicing clinicians. Responses from 542 clinicians were received and subsequently analysed and compared to outcomes from similar surveys from other regions. Results: A total of 542 respondents participated in the survey, 515 (95%) of whom completed all sections. Of these, 86% were medical specialists, 11% surgeons, and 3% nuclear medicine physicians. In addition to serum thyroid-stimulating hormone (TSH) and free thyroxine assays, most respondents would request TSH-receptor autoantibody (TRAb) measurement (68%) during initial work-up. Thyroid ultrasound is requested by about half of respondents (53%), while the use of nuclear medicine scans is limited. The preferred first-line treatment is anti-thyroid drug (ATD) therapy (79%) with methimazole (MMI) or carbimazole (CBZ), followed by radioiodine (RAI; 19%) and surgery (2%). In case of surgery, one-third of respondents would opt for a subtotal rather than a total thyroidectomy. In case of mild Graves orbitopathy (GO), ATDs (67%) remains the preferred treatment, but a larger proportion of clinicians prefer surgery (20%). For a patient with intention to conceive, the preferred treatment pattern remained unchanged, although propylthiouracil (PTU) became the preferred ATD-agent during the first trimester. In comparison to European and American practices, marked differences were noted in the relatively infrequent usage of nuclear medicine scans and the overall higher use of a ATDs and β-blockers and adjunctive ATD-treatment during RAI in the APAC-group.Conclusion: Although regional differences regarding the diagnosis and management of GD are apparent in this first pan-Asia-Pacific survey, this study reveals the overall approach to the management of this disease in Asia-Pacific generally tends to fall between the trends appreciated in the American and European cohorts.Item Emerging IBD demographics, phenotype and treatment in South Asia, South-East Asia and Middle East: preliminary findings from the IBD-Emerging Nations' Consortium(Blackwell Scientific Publications, 2022) Banerjee, R.; Pal, P.; Hilmi, I.; Ghoshal, U.C.; Desai, D.C.; Rahman, M.M.; Dutta, U.; Mohiuddin, S.A.; Al Mohannadi, M.; Philip, M.; Ramesh, G.N.; Niriella, M.A.; de Silva, A.P.; de Silva, H.J.; Pisespongsa, P.; Limsrivilai, J.; Aniwan, S.; Nawarathne, M.; Fernandopulle, N.; Aye, T.T.; Ni, N.; Al Awadhi, S.; Joshi, N.; Ngoc, P.T.V.; Kieu, T.V.; Nguyen, A.D.; Abdullah, M.; Ali, E.; Zeid, A.; Sollano, J.D.; Saberi, B.; Omar, M.; Mohsin, M.N.; Aftab, H.; Wai, T.M.; Shastri, Y.M.; Chaudhuri, S.; Ahmed, F.; Bhatia, S.J.; Travis, S.P.L.Abstract Background and aims Inflammatory bowel disease (IBD) is emerging in the newly industrialized countries of South Asia, South East Asia and the Middle East, yet epidemiological data are scarce. Methods: We performed a cross-sectional study of IBD demographics, disease phenotype and treatment across 38 centers in 15 countries of South Asia, South-East Asia and Middle East. Intergroup comparisons included gross national income (GNI) per capita. Results: Among 10,400 patients, ulcerative colitis (UC) was twice as common as Crohn's disease (CD), with a male predominance (UC 6678, CD 3495, IBD-Unclassified 227, 58% male). Peak age of onset was in the third decade, with a low proportion of elderly onset IBD (5% age >60). Familial IBD was rare (5%). The extent of UC was predominantly distal (proctitis/left sided 67%), with most being treated with mesalamine (94%), steroids (54%), or immunomodulators (31%). Ileocolic CD (43%) was commonest, with low rates of perianal disease (8%) and only 6% smokers. Diagnostic delay for CD was common (median 12 months; IQR 5-30). Treatment of CD included mesalamine, steroids and immunomodulator (61%, 51% and 56% respectively), but a fifth received empirical anti-tubercular therapy. Treatment with biologics was uncommon (4% UC,13% CD) which increased in countries with higher GNI per capita. Surgery rates were 0.1 (UC) and 2 (CD)/100 patient/years. Conclusions: The IBD-ENC cohort provides insight into IBD in South-East Asia and the Middle East, but is not yet population-based. UC is twice as common as CD, familial disease uncommon and rates of surgery are low. Biologic use correlates with per capita GNI.
