RESUMO
OBJECTIVE: We aimed to report the burden of bulimia nervosa (BN) in the Middle East and North Africa (MENA) region by age, sex, and sociodemographic index (SDI), for the period 1990-2019. METHODS: Estimates of the prevalence, incidence, and disability-adjusted life-years (DALYs) attributable to BN were retrieved from the Global Burden of Disease study 2019, between 1990 and 2019, for the 21 countries in the MENA region. The counts and age-standardized rates (per 100,000) were presented, along with their corresponding 95% uncertainty intervals. RESULTS: In 2019, the estimated regional age-standardized point prevalence and incidence rates of BN were 168.3 (115.0-229.6) and 178.6 (117.0-255.6) per 100,000, which represented 22.0% (17.5-27.2) and 10.4% (7.1-14.7) increases, respectively, since 1990. Moreover, in 2019 the regional age-standardized DALY rate was 35.5 (20.6-55.5) per 100,000, which was 22.2% (16.7-28.2) higher than in 1990. In 2019, Qatar (58.6 [34.3-92.5]) and Afghanistan (18.4 [10.6-29.2]) had the highest and lowest age-standardized DALY rates, respectively. Regionally, the age-standardized point prevalence of BN peaked in the 30-34 age group and was more prevalent among women. In addition, there was a generally positive association between SDI and the burden of BN across the measurement period. DISCUSSION: In the MENA region, the burden of BN has increased over the last three decades. Cost-effective preventive measures are needed in the region, especially in the high SDI countries. PUBLIC SIGNIFICANCE: This study reports the estimated burden of BN in the MENA region and shows that its burden has increased over the last three decades.

BACKGROUND: Alcohol consumption is a risk factor for a number of communicable and non-communicable diseases, including several types of cancer. This article reports the burden of cancers attributable to alcohol consumption by age, sex, location, sociodemographic index (SDI), and cancer type from 1990 to 2019. METHODS: The Comparative Risk Assessment approach was used in the 2019 Global Burden of Disease study to report the burden of cancers attributable to alcohol consumption between 1990 and 2019. RESULTS: In 2019, there were globally an estimated 494.7 thousand cancer deaths (95% uncertainty interval [UI], 439.7 to 554.1) and 13.0 million cancer disability-adjusted life-years (DALYs; 95% UI, 11.6 to 14.5) that were attributable to alcohol consumption. The alcohol-attributable DALYs were much higher in men (10.5 million; 95% UI, 9.2 to 11.8) than women (2.5 million; 95% UI, 2.2 to 2.9). The global age-standardized death and DALY rates of cancers attributable to alcohol decreased by 14.7% (95% UI, 6.4% to 23%) and 18.1% (95% UI, 9.2% to 26.5%), respectively, over the study period. Central Europe had the highest age-standardized death rates that were attributable to alcohol consumption(10.3; 95% UI, 8.7 to12.0). Moreover, there was an overall positive association between SDI and the regional age-standardized DALY rate for alcohol-attributable cancers. CONCLUSIONS: Despite decreases in age-standardized deaths and DALYs, substantial numbers of cancer deaths and DALYs are still attributable to alcohol consumption. Because there is a higher burden in males, the elderly, and developed regions (based on SDI), these groups and regions should be prioritized in any prevention programs.

STUDY QUESTION: What is the global, regional and national burden of polycystic ovary syndrome (PCOS), by age and socio-demographic index (SDI), over the period 1990-2019? SUMMARY ANSWER: In 2019, the global age-standardized point prevalence, incidence and years lived with disability (YLD) of PCOS were 30.4, 29.5 and 29.9 per 100â000 population, respectively. WHAT IS KNOWN ALREADY: Data from the Global Burden of Disease (GBD) study 2017 showed that the global age-standardized PCOS incidence rate increased 1.45% over the period 1990-2017. STUDY DESIGN, SIZE, DURATION: A systematic analysis of the PCOS prevalence, incidence and YLDs across 204 countries and territories was performed. PARTICIPANTS/MATERIALS, SETTING, METHODS: Data on the point prevalence, annual incidence and YLDs due to PCOS were retrieved from the GBD study 2019 for 204 countries and territories from 1990 to 2019. The counts and age-standardized rates (per 100â000) are presented, along with their corresponding 95% uncertainty intervals (UIs). MAIN RESULTS AND THE ROLE OF CHANCE: In 2019, the global age-standardized point prevalence and annual incidence rates for PCOS were 1677.8 (95% UI: 1166.0 to 2192.4) and 59.8 (95% UI: 41.7 to 78.9) per 100â000, which represents a 30.4% and 29.5% increase since 1990, respectively. Moreover, the global age-standardized YLD rate in 2019 was 14.7 (6.3-29.5), an increase of 29.9% since 1990. In 2019, Italy (7897.0), Japan (6298.7) and New Zealand (5419.1) had the highest estimated age-standardized point prevalences of PCOS. Globally, the number of prevalent cases and the point prevalence of PCOS peaked in the 25-29 years and 40-44 years age groups, respectively. Positive associations were found between the burden of PCOS and the SDI at the regional and national levels. LIMITATIONS, REASONS FOR CAUTION: Variations in how PCOS was defined is a major limitation that prevents valid comparisons between different regions. WIDER IMPLICATIONS OF THE FINDINGS: Globally, the burden of PCOS has increased at an alarming rate, making it a major public health concern. Increasing public awareness about this common condition, improving management options and increasing support to reduce factors which lead to further complications, need to be public health priorities. STUDY FUNDING/COMPETING INTEREST(S): The Bill and Melinda Gates Foundation, who were not involved in any way in the preparation of this manuscript, funded the GBD study. The Shahid Beheshti University of Medical Sciences, Tehran, Iran (Grant No. 28709) also supported the present report. The authors declare no competing interests. TRIAL REGISTRATION NUMBER: N/A.

OBJECTIVE: Diabetes mellitus is a prevalent endocrine disorder worldwide. Citrulline is an α-amino acid, which is abundant in watermelon, and a precursor of arginine and nitric oxide. Decreased bioavailability of nitric oxide is associated with insulin resistance. The present systematic review focused on the existing evidence of citrulline and watermelon extract effects on metabolic and inflammatory parameters in diabetes mellitus. METHODS: A systematic search of the databases PubMed, Scopus, EMBASE, ProQuest and Google Scholar was conducted for relevant papers published from inception until October 2018. All clinical trials, animal and in vitro studies published in the English language that assessed the role of citrulline and watermelon extract on diabetes mellitus, were eligible. Studies providing inadequate information were excluded. RESULTS: Out of 1262 articles we found, only eight articles met the inclusion criteria for analysis. In three studies an increase in the synthesis of nitric oxide was reported with citrulline and watermelon extract supplementation. Four studies showed a significant reduction in blood glucose after supplementation with watermelon extract, and two studies reported a decrease in a number of inflammatory biomarkers following citrulline supplementation. Although citrulline intake caused a significant reduction in HOMA-IR in one study, inconsistent results were revealed on the effects of citrulline and watermelon extract on insulin levels and lipid profile. CONCLUSION: Citrulline and watermelon extract could improve nitric oxide synthesis, glycaemic status and inflammation in diabetes mellitus. However, further studies are required to shed light on the underlying mechanisms.

BACKGROUND: Proinflammatory genes are highly expressed in several metabolic disorders associated with obesity. But it is not clarified whether gene expression levels and downstream inflammatory markers are related to the metabolic state or the presence of obesity. Hence, the present study aimed to compare Toll-Like Receptor 2 (TLR2), Myeloid Differentiation Factor 88 (MyD88), and NFĸB mRNA expression levels between metabolically healthy abdominally obese (MHAO) and metabolically unhealthy abdominally obese (MUAO) individuals. RESULTS: We compared mRNA expression levels of the genes as well as serum FFAs and IL-1ß in MUAO (n = 36) and MHAO (n = 34) groups. Serum FBS, TG, and HDL-C in addition to systolic and diastolic blood pressure were significantly higher in MUAO than MHAO groups (p < 0.05). The odds of MUAO was significantly decreased with high HDL-C (OR = 0.22, 95%CI: 0.08-0.63) and increased with high FBS (OR = 7.04, 95%CI: 1.42-34.69) and TG (OR = 30.55, 95%CI: 7.48-60.67). There were no significant differences in proinflammatory genes as well as serum FFAs and IL-1ß between the two groups. No associations were found between the genes expression and serum markers. However, NFĸB expression was significantly correlated with TLR2 and MyD88 (r = 0.747; p < 0.001). Significant correlations were also noticed between TLR2 and MyD88 expression as well as between serum FFAs and IL-1ß in each group (p < 0.001). CONCLUSION: Serum concentration of IL-1ß, FFAs, and mRNA expression levels of TLR2, MyD88, and NFĸB may be resulted from abdominal obesity and not be related to the presence or absence of metabolic health.

OBJECTIVE: Low-grade inflammation is a characteristic of various conditions, including obesity. Diet is regarded as a strong modifier of inflammation. The potential links between inflammatory properties of diet and adipokines as well as insulin resistance (IR) warrant further investigation. Therefore, this study aimed to examine the associations of the dietary inflammatory index (DII) with serum chemerin, omentin, and lipopolysaccharide-binding protein (LBP) as well as IR among apparently healthy obese adults. DESIGN: In this cross-sectional study, 171 abdominally obese subjects were recruited in the northwest of Iran. Demographic data, dietary intake, anthropometric indices, and physical activity (PA) were assessed. DII scores were calculated based on dietary intake, using a validated 168-item food frequency questionnaire (FFQ). Basal blood samples were collected to determine the biochemical parameters. A linear regression test with adjusted beta estimates was applied for data analysis. RESULT: Compared to those with higher DII score, the group with lower DII score (anti-inflammatory diet) had higher protein (83.62 ± 36.42 g vs. 71.61 ± 25.94 g) and lower carbohydrate (325.00 ± 125.76 g vs. 378.19 ± 137.69 g) intake. Participants with higher DII score had lower consumption of polyunsaturated and monounsaturated fats as well as fiber and higher saturated fats (p < .001). Those with elevated DII score had higher levels of chemerin (p = .034) and LBP (p = .040), compared to those with lower DII. Omentin showed no significant differences between groups with different DII scores. Additionally, people with a more proinflammatory diet had higher FBS (p = .005); however, other markers of IR did not differ by DII scores. CONCLUSIONS: The results suggest that increased inflammatory potential of diet, as indicated by higher DII score, is associated with elevated levels of chemerin and LBP. While DII was positively associated with FBS, no significant correlation was found for insulin and other indices of IR.

BACKGROUND: Older people are more likely to develop nutritional problems and timely diagnosis of malnutrition is crucial to prevent hazardous consequences following poor nutrition. AIMS: To evaluate the efficacy of Geriatric Nutritional Risk Index (GNRI) to assess nutritional status among non-hospitalized elderly, compared to mini nutritional assessment (MNA) among Iranian seniors. METHODS: One hundred and sixty-four subjects, aged ≥ 65 years old were recruited to our cross-sectional study from various districts of Tabriz (Tabriz, Iran). Anthropometric and biochemical measurements were performed, short- and long-form MNAs and GNRI were assessed in our study subjects. Sensitivity, specificity and predictive values of the three indices, agreement between them, and their correlation with anthropometric and biochemical parameters were evaluated. Receiver-operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off point for GNRI in our study population. RESULTS: GNRI had lower sensitivity (50, 57%), but optimal specificity (94, 93%) and lower negative predictive value (NPV; 68, 71%) compared to MNA-LF and MNA-SF, respectively. We found a moderate agreement between GNRI and MNA-SF (K = 0.52) and MNA-LF (K = 0.46) scores. Significant correlations were observed between re-categorized MNAs as well as GNRI scores, and age, weight, MAC, CC, WC, albumin, and pre-albumin. The cut-off point of 110.33 was obtained for GNRI, according to the ROC curve. CONCLUSIONS: Although GNRI may not be an efficient tool for screening malnutrition due to its lower sensitivity, it is moderately correlated with MNAs and also more useful when limited funding needs to target the truly malnourished seniors.

Background: Vitamin A deficiency (VAD) is a common micronutrient deficiency that imposes a substantial burden worldwide. This study examined the burden of VAD from 1990 to 2019 in the Middle East and North Africa (MENA) region by age, sex and sociodemographic index (SDI). Methods: The data were obtained from the Global Burden of Disease (GBD) 2019 database. We reported the prevalence, incidence, and years lived with disability (YLDs) that were attributable to VAD for the MENA region, along with its constituent countries. Results: In 2019, the MENA region had 30.6 million prevalent cases of VAD, with an age-standardized prevalence rate of 5249.9 per 100,000 population. In addition, VAD was responsible for 62.2 thousand YLDs, with an age-standardized YLD rate of 10.2 per 100,000. The age-standardized prevalence [50.3% (-55.9 to -44.7)] and YLD [-49.3% (-55.3 to -43.1)] rates of VAD have significantly decreased since 1990. In 2019, the MENA region's VAD-attributable YLD rate was below the global average for males and females across all age groups. Additionally, SDI was negatively associated the age-standardized YLD rate of VAD. Conclusion: This study underscores the necessity of frequently updating health data and developing guidelines and regulations to prevent, detect early, and effectively treat VAD in the MENA countries.
RESUMO
Background and Aims: Osteoarthritis (OA) is one of the most common debilitating diseases among the aging population. Nigella sativa is one potential treatment for OA. Here, we sought to evaluate the efficacy and safety of Nigella sativa for treating patients with OA. Methods: PubMed, Scopus, Embase, and Web of Science were searched up to October 20, 2022. The primary outcome was changes in the pain score after receiving Nigella sativa or control agents based on the results of randomized controlled trials (RCTs). The secondary outcome was set as the frequency of adverse events reported during the follow-up period. Results: Six RCTs involving a total of 370 patients with knee OA were included in the present systematic review. Among the four screened studies, the topical administration of Nigella sativa oil was found to be more effective than the placebo in relieving pain in three trials. Additionally, the oral use of Nigella sativa oil was assessed in two trials, and an improvement in pain score relative to placebo was documented in only one of the studies. Also, the trial that evaluated the effectiveness of Nigella sativa oral capsules did not demonstrate any difference in pain reduction between the intervention and placebo groups. Overall, either topical or oral administration of Nigella sativa was well tolerated, and no serious adverse events were reported. Conclusion: Nigella sativa is generally safe, but conflicting findings from low-quality studies hinder the ability to make clinical recommendations for or against treating OA. Robust trials are needed for informed decisions.
RESUMO
High body mass index (BMI), or excess body weight (EBW), represents a significant risk factor for a range of diseases, including cardiovascular diseases and cancers. The study sought to determine the burden of diseases attributable to EBW in the Middle East and North Africa (MENA) region from 1990 and 2019. The analysis also included an exploration of this burden by age, sex, underlying cause, and sociodemographic index (SDI). We utilized publicly available data from the Global Burden of Disease (GBD) study 2019 to identify the deaths and disability-adjusted life-years (DALYs) of diseases associated with EBW in MENA, spanning the period from 1990 to 2019. The GBD estimated the mean BMI and the prevalence of EBW using hierarchical mixed-effects regression, followed by spatiotemporal Gaussian process regression to determine the most accurate BMI distribution through comparison with actual data. In 2019, there were an estimated 538.4 thousand deaths (95% UI 369.9-712.3) and 17.9 million DALYs (12.9-23.1) attributable to EBW in the region. The DALYs attributable to EBW were higher in men (9.3 million [6.5-12.4]) than in women (8.5 million [6.4-10.8]). The age-standardized death and DALY rates for the diseases associated with EBW increased by 5.1% (- 9.0-25.9) and 8.3% (- 6.5-28.8), respectively, during the study period which was not significant. Egypt had the highest age-standardized mortality rate due to EBW (217.7 [140.0, 307.8]), while Yemen (88.6 [45.9, 143.5]) had the lowest. In 2019, the highest number of DALYs occurred among individuals aged 60 to 64 years old. Furthermore, we found a positive association between a nation's SDI and the age-standardized DALY rate linked to EBW. Cardiovascular disease emerged as the leading contributor to the EBW burden in MENA. The disease burden attributable to EBW showed a non-significant increase in MENA from 1990 to 2019.

Introduction: The Mediterranean diet is marked by the regular intake of olive oil, which may play a role in preventing and protecting against cognitive deterioration and dementia. The strength of these effects have been examined by several recent randomized controlled trials (RCTs), but their findings have not been consistent. In light of this inconsistency, the present study performed a systematic review to examine the relationship between the consumption of olive oil and cognition. Methods: The Web of Science, Scopus, PubMed, and Google Scholar were systematically searched up to August 11, 2023. The review included RCTs, cross-sectional studies, cohort studies and case-control studies that explored the impact of olive oil consumption on cognitive performance among those older than 55 years old. Studies were excluded if they employed a design other than those mentioned above, involved participants under 55 years old, or did not specifically examine the cognitive effects of olive oil consumption. The quality of the included studies were measured using the Cochrane risk-of-bias tool and the Newcastle Ottawa Scale checklists. Results: Eleven studies were identified, which were comprised of four cross-sectional studies, four prospective cohort studies and three RCTs. The cohort studies and RCTs consistently found that olive oil consumption had a favorable effect on cognitive performance across a number of cognitive domains over time. Similarly, all of the cross-sectional studies reported that the consumption of olive oil was positively associated with cognitive health. Conclusion: The consumption of olive oil was found to enhance cognitive functioning and to reduce cognitive decline. Further large-scale investigations are required to strengthen this conclusion.
RESUMO
BACKGROUND: Type 2 diabetes mellitus (T2DM) is a common disorder that is characterized by chronic hyperglycemia and chronic inflammation, which also have a reinforcing effect on each other. The present research studied the effects of menaquinone (MK-7) supplementation on serum dp-ucMGP (dephospho uncarboxylated Matrix Gla Protein), PIVKAII (Prothrombin Induced by Vitamin K Absence), inflammatory markers and body composition indices in type 2 diabetes mellitus (T2DM) patients. METHODS: This 12-week double-blind placebo-controlled randomized clinical trial allocated 60 T2DM patients equally into a MK-7 (200 mcg/day) group or a placebo group. All patients also received dietary advice at the beginning of study and their dietary intakes were checked using a 3-day food record. The body composition of each patient was also measured and their vitamin K status was assessed using the ELISA method to measure serum dp-ucMGP and PIVKAII. In addition, inflammatory status indices were also measured, including hsCRP (high-sensitivity C-reactive protein), IL-6 (interleukin-6) and TNF-α (tumor necrosis factor alpha). All measurements were made both before and after the intervention period. RESULTS: In total 45 patients completed the trial (MK-7 group = 23 and placebo group = 22). The calorie and macronutrient intake of the two groups were similar pre and post intervention. There were statistically significant increases in dietary vitamin K intake for both groups over the course of the study (p < 0.05), but the intergroup differences were not significant. The body composition indices (i.e., body fat percentage, fat mass, fat free mass, muscle mass, bone mass and total body water) were not significantly different between groups or across the trial. The serum levels of the vitamin K markers, PIVKAII and dp-ucMGP, decreased significantly in the MK-7 group over the course of the study (p < 0.05), but there was no decrease in the placebo group. However, after adjusting for the baseline levels and changes in vitamin K intake, the between group differences were only significant for PIVKAII (p < 0.05). Following the intervention, the serum levels of the inflammatory markers (hsCRP, IL-6, and TNF-α) were significantly lower in the MK-7 group (p < 0.05), but not in the placebo group. However, the between group differences in the inflammatory markers were not statistically significant. CONCLUSIONS: Although further studies are needed, it appears that MK-7 supplementation can be effective in improving PIVKAII levels, but not for improving dp-ucMGP, inflammatory status or the body composition indices of T2DM patients. TRIAL REGISTRATION NUMBER: This study was prospectively registered at the Iranian Registry of Clinical Trials on the 20th of May 2019 (ID: IRCT20100123003140N22).

Background: To report the burden of cancers attributable to high fasting plasma glucose (HFPG) by sex, age, location, cancer type and Socio-demographic Index (SDI) over the period 1990 to 2019 for 204 countries and territories. Methods: Using the Comparative Risk Assessment approach of Global Burden of Disease (GBD) study 2019, the burden of cancers attributable to HFPG was reported in 1990 and 2019. Results: Globally, in 2019 there were an estimated 419.3 thousand cancer deaths (95% UI: 115.7 to 848.5) and 8.6 million cancer DALYs (2.4 to 17.6) attributable to HFPG. By sex, 4.6 (1.1 to 9.9) and 4.0 (1.1 to 8.4) million global cancer DALYs were attributable to HFPG in men and women, respectively. The global age-standardized death and DALY rates of cancers attributable to HFPG (per 100,000) have increased by 27.8% (20.5 to 38.7%) and 24.5% (16.4 to 35.6%), respectively, since 1990. High-income North America (9.5 [2.7 to 18.8]) and Eastern Sub-Saharan Africa (2.0 [0.5 to 4.2]) had the highest and lowest regional age-standardized death rates, respectively, for cancers attributable to HFPG. In 2019, the global number of attributable cancer DALYs were highest in 65-69 age group. Moreover, there was an overall positive association between SDI and the regional age-standardized DALY rate for HFPG-attributable cancers. Conclusions: HFPG was associated with more burden in 2019. Preventive programs for diabetes and screening of individuals with diabetes for cancers, especially in older males living in developed countries, are required to arrest the large increases in HFPG-attributable cancers.

OBJECTIVE: The aim of this study was to report the level and trends of 13 cancers that are attributable to excess body weight (EBW) for 204 countries and territories from 1990 to 2019. METHODS: Using publicly available data, the burden of cancers attributable to EBW was reported from 1990 to 2019 based on the comparative risk assessment approach used in the Global Burden of Disease study 2019. [Correction added on 27 January 2022, after first online publication: 'Using publicly available data,' has been added before the first sentence and 'estimated' was corrected to 'reported'.] RESULTS: In 2019, EBW caused 11.2 million disability-adjusted life-years (DALYs), or 4.4% of all cancer-related DALYs. Between 1990 and 2019, the global EBW-attributable age-standardized cancer DALY rates (per 100,000) increased from 109.9 to 133.9, a relative increase of 21.9%. The age-standardized DALY rates (per 100,000) of cancers attributable to EBW in 2019 were highest and lowest in Mongolia (611.8) and Bangladesh (30.2), respectively. The 60- to 64-year age group had the highest number of DALYs attributable to EBW, whereas there were no large sex differences in the cancer-related burden attributable to EBW. Furthermore, the association between the age-standardized DALY rates and the sociodemographic index was generally positive. CONCLUSIONS: Overall, the EBW-attributable burden of cancers has increased in the past three decades. Public health efforts should focus on identifying appropriate preventive interventions at the population and individual levels, especially in the regions and countries with the highest burden.

AIMS: To report the prevalence, deaths, and disability-adjusted life years (DALYs) associated with ischemic heart disease (IHD) and its attributable risk factors in 204 countries and territories from 1990 to 2019, by age, sex, and socio-demographic index (SDI). METHODS AND RESULTS: Ischemic heart disease was defined as acute myocardial infarction (MI) and chronic IHD (angina; asymptomatic IHD following MI). Cause of death ensemble modelling was used to produce fatality estimates. The prevalence of the non-fatal sequalae of IHD was estimated using DisMod MR 2.1. All estimates were presented as counts and age-standardized rates per 100 000 population. In 2019, IHD accounted for 197.2 million (177.7-219.5) prevalent cases, 9.1 million (8.4-9.7) deaths, and 182.0 million (170.2-193.5) DALYs worldwide. There were decreases in the global age-standardized prevalence rates of IHD [-4.6% (-5.7, -3.6)], deaths [-30.8% (-34.8, -27.2)], and DALYs [-28.6% (-33.3, -24.2)] from 1990 to 2019. In 2019, the global prevalence and death rates of IHD were higher among males across all age groups, while the death rate peaked in the oldest group for both sexes. A negative association was found between the age-standardized DALY rates and SDI. Globally, high systolic blood pressure (54.6%), high low-density lipoprotein cholesterol (46.6%), and smoking (23.9%) were the three largest contributors to the DALYs attributable to IHD. CONCLUSION: Although the global age-standardized prevalence, death, and DALY rates all decreased. Prevention and control programmes should be implemented to reduce population exposure to risk factors, reduce the risk of IHD in high-risk populations, and provide appropriate care for communities.

BACKGROUND: Anorexia nervosa (AN) is a complex and heritable psychiatric disorder, which imposes significant mortality and morbidity on sufferers globally. We aimed to report the prevalence, incidence and disability-adjusted life-years (DALYs) attributable to AN in the Middle East and North Africa (MENA) region by age, sex and socio-demographic index (SDI), between 1990 and 2019. METHODS: The disease burden attributable to AN was obtained for the 21 countries located in the MENA region between 1990 and 2019 using publicly available data from the Global Burden of Disease (GBD) 2019 study. All estimates were provided as counts and age-standardized rates per 100,000 population, along with 95% uncertainty intervals (UIs). RESULTS: In 2019, the estimated age-standardised point prevalence and incidence rate of AN (per 100,000) in MENA were 49.3 (95% UI: 34.6-70.4) and 16.0 (11.3-22.0), which were 11.4% (7.3-15.4) and 5.9% (2.6-9.1) higher than in 1990, respectively. Furthermore, the regional age-standardised DALY rate was 10.6 (6.3-17.0) per 100,000 in 2019, which was 11.8% (5.2-19.1) higher than in 1990. In 2019, Kuwait [17.3 (10.3-27.9)] and Afghanistan [6.3 (3.7-10.3)] had the highest and lowest age-standardised DALY rates, respectively. In addition, Iran showed the largest increases in the age-standardised point prevalence [30.0% (24.1-36.2)], incidence [24.6% (18.6-30.4)] and DALY [30.5% (22.6-38.9)] rates between 1990 and 2019. In 2019, the number of prevalent cases and prevalence estimates peaked in the 15-19 age group for males and the 20-24 age group for females, with females having a higher number of cases and prevalence in all age groups. In 2019, the age-standardised DALY rates in MENA were higher than the global rates among males aged 10-34 years, but were lower than the global estimates among females in almost all age groups. In addition, the burden of AN was positively associated with the level of socio-economic development during the measurement period. CONCLUSIONS: The burden of AN in the MENA region increased between 1990 and 2019, which indicates that it is likely to become a more serious public health issue in the future. Up-to-date information about the epidemiological trends in the region would allow health policymakers to make informed and appropriate decisions to help address this issue. The findings of the present study showed that the point prevalence and incidence rate of anorexia nervosa have increased in the Middle East and North Africa region between 1990 and 2019. The highest burden in 2019 was found in Kuwait, while Afghanistan had the lowest attributable burden. In addition, between 1990 and 2019 Iran had the largest increase in the point prevalence of anorexia nervosa. Also in 2019, anorexia nervosa was more prevalent in females and peaked in the 15-19 age group for males and the 20-24 age group for females. Furthermore, as the level of socioeconomic development increased, so did the burden attributable to anorexia nervosa.
RESUMO
BACKGROUND: Understanding global trends in the point prevalence, deaths, and disability-adjusted life-years (DALYs) for asthma will facilitate evidence-based decision-making. RESEARCH QUESTION: What are the global, regional, and national burdens of asthma in 204 countries and territories between 1990 and 2019 by age, sex, and sociodemographic index (SDI)? STUDY DESIGN AND METHODS: Publicly available data from the Global Burden of Disease study from 1990 through 2019 were used. All estimates were presented as counts and age-standardized rates per 100,000, along with their associated uncertainty intervals. RESULTS: In 2019, the global age-standardized point prevalence and death rates for asthma were 3,415.5 and 5.8 per 100,000, which represent a 24% and 51.3% decrease since 1990, respectively. Moreover, in 2019, the global age-standardized DALY rate was 273.6 and the global point prevalence of asthma was highest in the group 5 to 9 years of age. Also in 2019, the United States (10,399.3) showed the highest age-standardized point prevalence rate of asthma. Generally, the burden of asthma decreased with increasing SDI. Globally, high BMI (16.9%), smoking (9.9%), and occupational asthmagens (8.8%) contributed to the 2019 asthma DALYs. INTERPRETATION: Asthma remains an important public health issue, particularly in regions with low socioeconomic development. Future research is needed to examine thoroughly the associations asthma has with its risk factors and the factors impeding optimal self-management. Further research also is needed to understand and implement better the interventions that have reduced the burden of asthma.

Aim: To report the point prevalence, deaths and disability-adjusted-life-years (DALYs) due to type 2 diabetes and its attributable risk factors in 204 countries and territories during the period 1990-2019. Methods: We used the data of the Global Burden of Disease (GBD) Study 2019 to report number and age-standardised rates per 100 000 population of type 2 diabetes. Estimates were reported with 95% uncertainty intervals (UIs). Results: In 2019, the global age-standardised point prevalence and death rates for type 2 diabetes were 5282.9 and 18.5 per 100 000, an increase of 49% and 10.8%, respectively, since 1990. Moreover, the global age-standardised DALY rate in 2019 was 801.5 per 100 000, an increase of 27.6% since 1990. In 2019, the global point prevalence of type 2 diabetes was slightly higher in males and increased with age up to the 75-79 age group, decreasing across the remaining age groups. American Samoa [19876.8] had the highest age-standardised point prevalence rates of type 2 diabetes in 2019. Generally, the burden of type 2 diabetes decreased with increasing SDI (Socio-demographic Index). Globally, high body mass index [51.9%], ambient particulate matter pollution [13.6%] and smoking [9.9%] had the three highest proportions of attributable DALYs. Conclusion: Low and middle-income countries have the highest burden and greater investment in type 2 diabetes prevention is needed. In addition, accurate data on type 2 diabetes needs to be collected by the health systems of all countries to allow better monitoring and evaluation of population-level interventions.

OBJECTIVES: To perform a meta-analysis on the relationship type 2 diabetes has with serum hepcidin and the hepcidin/ferritin ratio. METHODS: The following databases were searched using all relevant keywords: Web of Science, Medline, Scopus, Embase and Google Scholar. All studies that examined the relationship type 2 diabetes has with serum hepcidin or the hepcidin/ferritin ratio were included in this meta-analysis and systematic review provided, were published in English between 2011 and 2018. A random-effects model was used to pool the standardized mean difference (SMD). RESULTS: The SMD of serum hepcidin among patients with type 2 diabetes and healthy controls were compared across eight studies (n cases=878; n controls=2306). The pooled SMD of serum hepcidin did not differ significantly between study groups (SMD: 0.04; 95% confidence interval (CI): -0.29 to 0.35). In contrast, the serum hepcidin/ferritin ratio was examined across five studies (n cases=229; n controls=1426) and was found to be negatively associated with the risk of type 2 diabetes (SMD: -0.52; 95% confidence interval (CI): -0.85 to -0.19). There was no publication bias found for the associations serum hepcidin (Egger´s test: P =0.97) or the hepcidin/ferritin ratio (Egger´s test: P =0.75) had with type 2 diabetes. CONCLUSION: Although hepcidin has been proposed as a risk marker for type 2 diabetes, our metaanalysis found that the hepcidin/ferritin ratio was superior to hepcidin alone as a risk marker.
