Background The burden of inflammatory bowel disease (IBD) is rising globally, with substantial variation in levels and trends of disease in different countries and regions. Understanding these geographical differences is crucial for formulating effective strategies for preventing and treating IBD. We report the prevalence, mortality, and overall burden of IBD in 195 countries and territories between 1990 and 2017, based on data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017.Methods We modelled mortality due to IBD using a standard Cause of Death Ensemble model including data mainly from vital registrations. To estimate the non-fatal burden, we used data presented in primary studies, hospital discharges, and claims data, and used DisMod-MR 2.1, a Bayesian meta-regression tool, to ensure consistency between measures. Mortality, prevalence, years of life lost (YLLs) due to premature death, years lived with disability (YLDs), and disability-adjusted life-years (DALYs) were estimated. All of the estimates were reported as numbers and rates per 100 000 population, with 95% uncertainty intervals (UI). Findings In 2017, there were 6•8 million (95% UI 6•4-7•3) cases of IBD globally. The age-standardised prevalence rate increased from 79•5 (75•9-83•5) per 100 000 population in 1990 to 84•3 (79•2-89•9) per 100 000 population in 2017. The age-standardised death rate decreased from 0•61 (0•55-0•69) per 100 000 population in 1990 to 0•51 (0•42-0•54) per 100 000 population in 2017. At the GBD regional level, the highest age-standardised prevalence rate in 2017 occurred in high-income North America (422•0 [398•7-446•1] per 100 000) and the lowest agestandardised prevalence rates were observed in the Caribbean (6•7 [6•3-7•2] per 100 000 population). High Sociodemographic Index (SDI) locations had the highest age-standardised prevalence rate, while low SDI regions had the lowest age-standardised prevalence rate. At the national level, the USA had the highest age-standardised prevalence rate (464•5 [438•6-490•9] per 100 000 population), followed by the UK (449•6 [420•6-481•6] per 100 000). Vanuatu had the highest age-standardised death rate in 2017 (1•8 [0•8-3•2] per 100 000 population) and Singapore had the lowest (0•08 [0•06-0•14] per 100 000 population). The total YLDs attributed to IBD almost doubled over the study period, from 0•56 million (0•39-0•77) in 1990 to 1•02 million (0•71-1•38) in 2017. The agestandardised rate of DALYs decreased from 26•5 (21•0-33•0) per 100 000 population in 1990 to 23•2 (19•1-27•8) per 100 000 population in 2017.Interpretation The prevalence of IBD increased substantially in many regions from 1990 to 2017, which might pose a substantial social and economic burden on governments and health systems in the coming years. Our findings can be useful for policy makers developing strategies to tackle IBD, including the education of specialised personnel to address the burden of this complex disease.Funding Bill & Melinda Gates Foundation.

Background Cirrhosis and other chronic liver diseases (collectively referred to as cirrhosis in this paper) are a major cause of morbidity and mortality globally, although the burden and underlying causes differ across locations and demographic groups. We report on results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 on the burden of cirrhosis and its trends since 1990, by cause, sex, and age, for 195 countries and territories. Methods We used data from vital registrations, vital registration samples, and verbal autopsies to estimate mortality. We modelled prevalence of total, compensated, and decompensated cirrhosis on the basis of hospital and claims data. Disability-adjusted life-years (DALYs) were calculated as the sum of years of life lost due to premature death and years lived with disability. Estimates are presented as numbers and age-standardised or age-specific rates per 100 000 population, with 95% uncertainty intervals (UIs). All estimates are presented for five causes of cirrhosis: hepatitis B, hepatitis C, alcohol-related liver disease, non-alcoholic steatohepatitis (NASH), and other causes. We compared mortality, prevalence, and DALY estimates with those expected according to the Socio-demographic Index (SDI) as a proxy for the development status of regions and countries. Findings In 2017, cirrhosis caused more than 1•32 million (95% UI 1•27-1•45) deaths (440 000 [416 000-518 000; 33•3%] in females and 883 000 [838 000-967 000; 66•7%] in males) globally, compared with less than 899 000 (829 000-948 000) deaths in 1990. Deaths due to cirrhosis constituted 2•4% (2•3-2•6) of total deaths globally in 2017 compared with 1•9% (1•8-2•0) in 1990. Despite an increase in the number of deaths, the age-standardised death rate decreased from 21•0 (19•2-22•3) per 100 000 population in 1990 to 16•5 (15•8-18•1) per 100 000 population in 2017. Sub-Saharan Africa had the highest age-standardised death rate among GBD super-regions for all years of the study period (32•2 [25•8-38•6] deaths per 100 000 population in 2017), and the high-income super-region had the lowest (10•1 [9•8-10•5] deaths per 100 000 population in 2017). The age-standardised death rate decreased or remained constant from 1990 to 2017 in all GBD regions except eastern Europe and central Asia, where the age-standardised death rate increased, primarily due to increases in alcohol-related liver disease prevalence. At the national level, the age-standardised death rate of cirrhosis was lowest in Singapore in 2017 (3•7 [3•3-4•0] per 100 000 in 2017) and highest in Egypt in all years since 1990 (103•3 [64•4-133•4] per 100 000 in 2017). There were 10•6 million (10•3-10•9) prevalent cases of decompensated cirrhosis and 112 million (107-119) prevalent cases of compensated cirrhosis globally in 2017. There was a significant increase in age-standardised prevalence rate of decompensated cirrhosis between 1990 and 2017. Cirrhosis caused by NASH had a steady age-standardised death rate throughout the study period, whereas the ot...

Plant-derived functional foods are gaining considerable attention due to their safety and therapeutic potentials. Research on plant-based functional foods presents several challenges ranges from hypercholesterolemia to cancer prevention. In last decade, special attention has been paid to edible plants and especially their phytochemicals. Today, there is an increasing interest in their bioactivities provided by these phytochemicals. Polyphenols are the most numerous and widely distributed group of bioactive molecules. Polyphenols have two general classes, one is flavonoids and other is phenolic acids. Among these, flavonoids are further divided into flavones, flavononse, flavonols, flavanols, isoflavones, and phenolic acids are generally classified into hydroxybenzoic and hydroxycinnamic acids. Fruit peel is one of the dense sources for flavonoids and their content may vary from species to species and due to exposure of light. Polyphenols have wide range of molecules and different set of biological activities that are mainly attributed to their structure. Investigations have revealed that polyphenols play a key role to prevent various diseases, like hypercholesterolemia, hyperglycemia, hyperlipidemia, and cancer insurgence. The current review article summarizes the literature pertaining to polyphenols and its allied health benefits.
