BACKGROUND AND AIM: 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, and 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 the commonest, with low rates of perianal disease (8%) and only 6% smokers. Diagnostic delay for CD was common (median 12 months; interquartile range 5-30). Treatment of CD included mesalamine, steroids, and immunomodulators (61%, 51%, and 56%, respectively), but a fifth received empirical antitubercular therapy. Treatment with biologics was uncommon (4% UC and 13% CD), which increased in countries with higher GNI per capita. Surgery rates were 0.1 (UC) and 2 (CD) per 100 patients per year. 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 is uncommon, and rates of surgery are low. Biologic use correlates with per capita GNI.

Abstract Ulcerative colitis is one of the IBDs. Its etiology and pathogenesis remain undefined with an interaction between environmental, genetic and immunological factors is the most accepted explanation. Several recent studies have examined microRNA expression in the peripheral blood and tissues from IBD patients. The study aims at assessing the expression of serum miR-16 in ulcerative colitis patients and its correlation with disease extent, activity and severity. It included 30 treatment naïve ulcerative colitis patients of different presentations. Serum miR-16 expression was assessed using reverse transcriptase quantitative real time PCR (RT-qPCR), and then correlated with that of a group of 20 healthy subjects to assess its role in diagnosis of ulcerative colitis. Also, it was correlated with disease extent (proctitis, left sided colitis, extensive colitis) and disease activity and severity indices (Truelove and Witts criteria, fecal calprotectin and UCEIS). Thirty ulcerative colitis patients were enrolled, 53% had mild, 37% had moderate, while 10% had severe disease. Concerning endoscopic extent, 8 had proctitis, 14 had left sided colitis and 8 had extensive colitis. Serum expression of miR-16 in the 30 patients were compared to that of the healthy control subjects. The patients' group showed median serum miR-16 expression of 1.91, 1.13 for the control group with a significant difference between both groups. Correlation between serum miR-16 expression with disease extent, activity and severity showed no significant relation. From the current study we can conclude that increased serum expression of miR-16 is associated with ulcerative colitis despite no significant relation to disease activity extent or severity.


Resumo A colite ulcerativa é uma das DII. Sua etiologia e patogênese permanecem indefinidas; a interação entre fatores ambientais, genéticos e imunológicos é a explicação mais aceita. Vários estudos recentes avaliaram a expressão de microRNA no sangue e tecidos periféricos em pacientes com DII. O presente estudo teve como objetivo avaliar a expressão do miR-16 sérico em pacientes com colite ulcerativa e sua correlação com a extensão, atividade e gravidade da doença. Foram incluídos 30 pacientes de colite ulcerativa, com diferentes apresentações, que ainda não haviam sido submetidos a nenhum tipo de tratamento. A expressão sérica de miR-16 foi avaliada usando transcrição reversa seguida de reação em cadeia da polimerase quantitativa (RT-qPCR) e, em seguida, correlacionada com a de um grupo de 20 indivíduos saudáveis para avaliar seu papel no diagnóstico de colite ulcerativa. Além disso, foi feita uma correlação com a extensão da doença (proctite, colite do lado esquerdo, colite extensa) e com os índices de atividade e gravidade da doença (critérios de Truelove e Witts, calprotectina fecal e UCEIS). Trinta pacientes com colite ulcerativa foram incluídos no estudo, classificada como leve em 53%, moderada em 37% e grave em 10%. Quanto à extensão endoscópica, oito apresentavam proctite, 14 apresentavam colite do lado esquerdo e oito apresentavam colite extensa. A expressão sérica de miR-16 nos 30 pacientes foi comparada à dos indivíduos controle saudáveis. No, grupo de pacientes, a expressão sérica de miR-16 foi de 1,91 (grupo controle: 1,13), uma diferença estatisticamente significativa entre os dois grupos. Não foi observada relação significativa entre a expressão sérica de miR-16 e a extensão, atividade e gravidade da doença. A partir do presente estudo, pode-se concluir que o aumento da expressão sérica do miR-16 está associado à colite ulcerativa, apesar de não haver relação significativa com a extensão ou gravidade da atividade da doença.

The early detection of SARS-CoV-2, the causative agent of (COVID-19) is now a critical task for the clinical practitioners. The COVID-19 spread is announced as pandemic outbreak between people worldwide by WHO since 11/ March/ 2020. In this consequence, it is top critical priority to become aware of the infected people so that prevention procedures can be processed to minimize the COVID-19 spread and to begin early medical health care of those infected persons. In this paper, the deep studying based totally methodology is usually recommended for the detection of COVID-19 infected patients using X-ray images. The help vector gadget classifies the corona affected X-ray images from others through usage of the deep features. The technique is useful for the clinical practitioners for early detection of COVID-19 infected patients. The suggested system of multi-level thresholding plus SVM presented high accuracy in classification of the infected lung with Covid-19. All images were of the same size and stored in JPEG format with 512 * 512 pixels. The average sensitivity, specificity, and accuracy of the lung classification using the proposed model results were 95.76%, 99.7%, and 97.48%, respectively.
