RESUMEN

Importance: Stroke is a leading cause of death and disability in the US. Accurate and updated measures of stroke burden are needed to guide public health policies. Objective: To present burden estimates of ischemic and hemorrhagic stroke in the US in 2019 and describe trends from 1990 to 2019 by age, sex, and geographic location. Design, Setting, and Participants: An in-depth cross-sectional analysis of the 2019 Global Burden of Disease study was conducted. The setting included the time period of 1990 to 2019 in the US. The study encompassed estimates for various types of strokes, including all strokes, ischemic strokes, intracerebral hemorrhages (ICHs), and subarachnoid hemorrhages (SAHs). The 2019 Global Burden of Disease results were released on October 20, 2020. Exposures: In this study, no particular exposure was specifically targeted. Main Outcomes and Measures: The primary focus of this analysis centered on both overall and age-standardized estimates, stroke incidence, prevalence, mortality, and DALYs per 100 000 individuals. Results: In 2019, the US recorded 7.09 million prevalent strokes (4.07 million women [57.4%]; 3.02 million men [42.6%]), with 5.87 million being ischemic strokes (82.7%). Prevalence also included 0.66 million ICHs and 0.85 million SAHs. Although the absolute numbers of stroke cases, mortality, and DALYs surged from 1990 to 2019, the age-standardized rates either declined or remained steady. Notably, hemorrhagic strokes manifested a substantial increase, especially in mortality, compared with ischemic strokes (incidence of ischemic stroke increased by 13% [95% uncertainty interval (UI), 14.2%-11.9%]; incidence of ICH increased by 39.8% [95% UI, 38.9%-39.7%]; incidence of SAH increased by 50.9% [95% UI, 49.2%-52.6%]). The downturn in stroke mortality plateaued in the recent decade. There was a discernible heterogeneity in stroke burden trends, with older adults (50-74 years) experiencing a decrease in incidence in coastal areas (decreases up to 3.9% in Vermont), in contrast to an uptick observed in younger demographics (15-49 years) in the South and Midwest US (with increases up to 8.4% in Minnesota). Conclusions and Relevance: In this cross-sectional study, the declining age-standardized stroke rates over the past 3 decades suggest progress in managing stroke-related outcomes. However, the increasing absolute burden of stroke, coupled with a notable rise in hemorrhagic stroke, suggests an evolving and substantial public health challenge in the US. Moreover, the significant disparities in stroke burden trends across different age groups and geographic locations underscore the necessity for region- and demography-specific interventions and policies to effectively mitigate the multifaceted and escalating burden of stroke in the country.

RESUMEN

BACKGROUND: The North Africa and Middle East (NAME) region has one of the highest burdens of ischemic heart disease (IHD) worldwide. This study reports the contemporary epidemiology of IHD in NAME. METHODS AND RESULTS: We estimated the incidence, prevalence, deaths, years of life lost, years lived with disability, disability-adjusted life years (DALYs), and premature mortality of IHD, and its attributable risk factors in NAME from 1990 to 2019 using the results of the GBD (Global Burden of Disease study 2019). In 2019, 0.8 million lives and 18.0 million DALYs were lost due to IHD in NAME. From 1990 to 2019, the age-standardized DALY rate of IHD significantly decreased by 33.3%, mostly due to the reduction of years of life lost rather than years lived with disability. In 2019, the proportion of premature death attributable to IHD was higher in NAME compared with global measures: 26.8% versus 16.9% for women and 18.4% versus 14.8% for men, respectively. The age-standardized DALY rate of IHD attributed to metabolic risks, behavioral risks, and environmental/occupational risks significantly decreased by 28.7%, 37.8%, and 36.4%, respectively. Dietary risk factors, high systolic blood pressure, and high low-density lipoprotein cholesterol were the top 3 risks contributing to the IHD burden in most countries of NAME in 2019. CONCLUSIONS: In 2019, IHD was the leading cause of death and lost DALYs in NAME, where premature death due to IHD was greater than the global average. Despite the great reduction in the age-standardized DALYs of IHD in NAME from 1990 to 2019, this region still had the second-highest burden of IHD in 2019 globally.

RESUMEN

BACKGROUND: Cardiovascular Disease (CVD) is the leading cause of death in developing countries. CVD risk stratification guides the health policy to make evidence-based decisions. AIM: To provide current picture and future trend of CVD risk in the adult Iranian population. METHODS: Nationally representative datasets of 2005, 2006, 2007, 2008, 2009, 2011, and 2016 STEPwise approach to non-communicable diseases risk factor surveillance (STEPS) studies were used to generate the 10-year and 30-year risks of CVD based on Framingham, Globorisk, and World Health Organization (WHO) risk estimation models. Trend of CVD risk was calculated from 2000 until 2016 and projected to 2030. RESULTS: In 2016, based on Framingham model, 14.0% of the Iranian, aged 30 to 74, were at great risk (≥20%) of CVD in the next 10 years (8.0% among females, 20.7% among males). Among those aged 25 to 59, 12.7% had ≥45% risk of CVD in the coming 30 years (9.2% among females, 16.6 among males). In 2016, CVD risk was higher among urban area inhabitants. Age-standardized Framingham 10-year CVD risk will increase 32.2% and 19%, from 2000 to 2030, in females and males, respectively. Eastern provinces had the lowest and northern provinces had the greatest risk. CONCLUSIONS: This study projected that CVD risk has increased from 2000 to 2016 in Iran. Without further risk factor modification, this trend will continue until 2030. We have identified populations at higher risks of CVD to guide future intervention.

RESUMEN

BACKGROUND: X-linked severe combined immunodeficiency is caused by IL2RG gene mutation. Several variations have been identified in the IL2RG gene, which potentially can prevent the production of nonfunctional proteins. Herein, a novel X-linked variant in the IL2RG gene is reported in twin brothers, associated with inflammatory bowel symptoms. CASE PRESENTATION: The patients were 26-month-old monozygotic twin middle-eastern males with failure to thrive and several inpatient admissions due to severe chronic nonbloody diarrhea that started at the age of 12 months. Pancolitis was revealed after performing upper and lower gastrointestinal endoscopies on the twin with more severe gastrointestinal symptoms. Flow cytometric evaluation of the peripheral blood cells showed low levels of CD4+ cells in both patients. Next generation sequencing-based gene panel test results of the two patients proved a novel heterozygous missense X-linked IL2RG mutation (70330011 A > G, p.Trp197Arg) in one of the patients, which was predicted to be deleterious (CADD score of 28), which soon after was confirmed by Sanger segregation in his twin brother. Both parents were wild types and had never experienced similar symptoms. The patients received an human leukocyte antigen (HLA)-matched cord blood transplant. The twin with more severe gastrointestinal symptoms died 1 month after transplantation. In his brother, watery diarrhea eventually subsided after transplantation. CONCLUSION: Intestinal involvement in X-linked severe combined immunodeficiency is a rare presentation that might be neglected. The increasing availability of genetic screening tests worldwide could be helpful for early detection of such lethal primary immunodeficiency diseases and in implementing effective interventions to handle the severe outcomes.

RESUMEN

BACKGROUND: There is an evolving need to evaluate atrial fibrillation/atrial flutter (AF/AFL) mortality trends across races, sexes, geographic regions and urbanization statuses to better understand management inequalities. METHODS: This observational study utilized the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database. Mortality rates due to AF/AFL as underlying and contributing causes of death between 2010 and 2020 were investigated. Mortality trends due to AF/AFL as contributing causes of death for different races, sexes, census regions and urbanization statuses were analyzed using annual percentage change (APC), and Joinpoint regression analysis. RESULTS: Mortality from AF/AFL as the underlying cause was increasing across the US until 2016 (APC 4.8%), followed by a plateau 2016-2020 (APC 0.0 %). Conversely, the mortality rate due to AF/AFL as a contributing cause increases 2010-2020 (APC 3.3%). The mortality rate in both sexes significantly increased in almost all groups, with the largest increase seen in Non-Hispanic Black males. Rural areas had a higher mortality rate (36.9 and 22.9 per 100,000 for males and females in 2020, respectively) and higher slope of increase than urban areas in total US population. Non-Hispanic White people had greater mortality than Non-Hispanic Black people; however, Non-Hispanic Black mortality rates are increasing at a faster rate in urban areas. CONCLUSION: AF/AFL as the underlying cause of death has plateaued from 2016 across the US 2010-2020; whilst AF/AFL as contributing cause of death is increasing. Significant discrepancies in mortality rates are identified between races and urbanization status.

RESUMEN

Background Recent research has revealed that vasovagal syncope (VVS) leads to a high incidence of injuries; however, clinical associations of injury are not well-established. We present data from an ongoing VVS cohort and aimed to determine characteristics associated with VVS-related injury. Methods and Results Between 2017 and 2020, consecutive patients ≥18 years of age presenting to a tertiary syncope unit and diagnosed with VVS were included. Clinical characteristics relevant to syncope were obtained for the index episode. The outcome was incidence of injury during VVS, documented by clinical evaluation at the syncope clinic. Among 1115 patients (mean age, 45.9 years; 48% women), 260 injuries (23%) occurred. History of VVS-related injuries (adjusted relative risk [aRR], 1.80 [95% CI, 1.42-2.29]), standing position (aRR, 1.34 [95% CI, 1.06-1.68]), and female sex (aRR, 1.30 [95% CI, 1.06-1.60]) were associated with injury, whereas recurrent VVS (aRR, 0.63 [95% CI, 0.49-0.81]) and syncope in the noon/afternoon (aRR, 0.70 [95% CI, 0.56-0.87]) and evening/night (aRR, 0.43 [95% CI, 0.33-0.57]) compared with morning hours were associated with lower risk. There was a trend for higher rates of injury with overweight/obesity (aRR, 1.23 [95% CI, 0.99-1.54]) and syncope occurring at home (aRR, 1.22 [95% CI, 0.98-1.51]). In a per-syncope analysis considering up to 3 previous episodes (n=2518, 36% traumatic), syncope at home (aRR, 1.33 [95% CI, 1.17-1.51]) and absence of prodromes (aRR, 1.34 [95% CI, 1.09-1.61]) were associated with injury. Conclusions Patient characteristics, VVS presentations, the circumstances, and surroundings can determine the risk of injury. These associations of VVS-related injury identify at-risk individuals and high-risk situations. Future prospective studies are needed to investigate potential strategies for prevention of post-VVS injury in recurrent cases.

RESUMEN

BACKGROUND: Immunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome is a rare autosomal recessive disorder. ICF1 is caused by bi-allelic mutations in the gene encoding deoxyribonucleic acid methyltransferase-3B (DNMT3B). Herein, we report a novel homozygous DNMT3B mutation in a patient with ICF1. CASE PRESENTATION: An eight-month-old Iranian Caucasian infant of consanguineous 1st-degree cousins presented to our clinic for evaluation of neutropenia. Physical examination was unremarkable except for low-set ears and a systolic cardiac murmur. He had a history of recurrent respiratory infections and oral thrush. Moreover, a collateral artery between the bronchial and pulmonary arteries was observed on the angiogram, mimicking a patent ductus arteriosus on the echocardiogram. Growth percentiles were normal; however, he had a neurodevelopmental delay. Family history was significant for a sibling who deceased at nine months of age after recurrent respiratory infections. Laboratory evaluation revealed a normal white blood cell count with neutropenia and normal bone marrow studies. He had hypogammaglobinemia with normal flow cytometric studies and was treated with prophylactic trimethoprim-sulfamethoxazole and itraconazole. After that, he was re-admitted three times due to recurrent episodes of pneumonia and an episode of pseudomonas aeruginosa meningitis. Currently, he is five years old and doing well on monthly intravenous immunoglobulin. Due to recurrent infections, hypogammaglobulinemia, and neutropenia, as well as a family history of consanguinity and a sibling who deceased during infancy, a primary immune deficiency was suspected. Genetic studies utilizing whole-exome sequencing demonstrated a homozygous missense mutation in DNMT3B (LRG_56t1:c.2008C>T; p.Arg670Trp) in the patient studied. The mutation has not been previously reported. CONCLUSION: We describe a novel homozygous DNMT3B mutation in an Iranian boy with ICF1. It is associated with recurrent infections, hypogammaglobinemia, neutropenia, mild facial anomalies, and a bronchopulmonary collateral artery.

RESUMEN

Cardiovascular disease (CVD) is the major leading cause of morbidity and mortality worldwide. According to the pro-inflammatory nature of CVD, recent studies highlighted the immune system's role in its pathogenesis and development. Toll-like receptors (TLRs) have been identified as dominant innate immune receptors. TLR-7 is an intracellular receptor expressed on endosomes or cytoplasmic reticulum and is responsible for detecting damage-associated molecular patterns, which are remarkable during inflammation and viral infection. In addition to immune cells, TLR-7 is expressed in endothelial cells, vascular smooth muscle cells, and platelets. TLR-7 ligands are single-stranded ribonucleic acid (ssRNA) and short interfering RNA, which can activate the signaling pathway and lead to both inflammatory (e.g., interleukin-1 (IL-1), IL-6, IL-12, tumor necrosis factor- α (TNF-α)) and anti-inflammatory (e.g., IL-10) cytokines release. By growing evidence, it has been proven that TLR-7 activated platelets can increase the risk of thrombus formation by neutrophil aggregation. At the same time, they have a protective role against thrombosis by releasing granulocyte-macrophage colony-stimulating factors. The same two-sided effect was observed between TLR-7 and atherosclerotic plaque formation. Moreover, recent studies explained an association between TLR-7 activation and increased risk of complete heart block, myocarditis, left ventricular remodeling, and rupture. Here we review the rapid progress that has been made in this field, which has improved our understanding of TLR-7 function in CVDs, and discuss the current treatments targeting this receptor.

RESUMEN

Through tightly controlled multilayer mechanisms, vascular endothelial growth factor receptor-2 (VEGFR-2) activation and its downstream signal transduction govern vasculogenesis and pathological angiogenesis, such as tumor angiogenesis. Therefore, it is critical to understand the molecular mechanisms governing VEGFR-2 signal transduction. We report that protein arginine methyltransferase 4 (PRMT4) via its highly conserved EVH1 and PH domain-like N-terminal domain binds to VEGFR-2 and mediates methylation of the juxtamembrane arginine 817 (R817) on VEGFR-2. Methylation of R817 selectively increases phosphorylation of tyrosine 820 (Y820). Phosphorylation of Y820 facilitates the c-Src binding with VEGFR-2 via Src homology domain 2 (SH2). Interfering with the methylation of R817 or phosphorylation of Y820 inhibits VEGFR-2-induced filopodia protrusions, a process that is critical for the core angiogenic responses of VEGFR-2. Methylation of R817 is an important previously unrecognized mechanism of the angiogenic signaling of VEGFR-2, with implications for the development of novel-targeted VEGFR-2 inhibitors.

RESUMEN

BACKGROUND: Asthma is a chronic inflammatory disease of airways which accounts for a huge economic, morbidity and mortality burden. There are different cytokines that contribute to asthma pathophysiology. Learning about these cytokines leads to attaining novel anti-inflammatory treatments for asthma control. OBJECTIVES: The objective of this study is to investigate the association between interleukin-9 serum level and gene polymorphism with asthma susceptibility. METHODS: This was a case-control study of 70 asthmatic patients and 77 healthy control adults aged 18-60. Asthma diagnosis and severity were based on physician diagnosis, pulmonary function test (PFT) and 2016 guild line of Global Initiative for Asthma (GINA). Interleukin 9(IL -9) serum level was measured using sandwich enzyme linked immunosorbent assay.  IL9 promoter single nucleotide polymorphism (SNP) (rs2069882) was also assessed using Real-Time PCR System. RESULTS: There was no significant association between IL-9 SNP polymorphism and asthma. IL-9 serum level was significantly associated with asthma susceptibility (p value= 0.016) and absolute eosinophil count (AEC) (P value=0.033) however its corelation with atopic asthma type, asthma sivierity and Immunoglubin E serum level were not statistically significant. CONCLUSION: Although there was no association between IL-9 SNP and asthma, but IL-9 serum level was significantly correlated with asthma susceptibility and AEC.

RESUMEN

Air pollution exposures have been suggested as risk factors for childhood respiratory diseases. We investigated proximity to major roads, an indicator of air pollution exposure, and its associations with childhood recurrent wheeze and asthma. We used data from a multicenter prospective cohort study of 921 infants hospitalized for bronchiolitis and recruited from 14 U.S. states. Primary exposure was residential proximity to the nearest major road at birth through age 3 years. Residential distance from nearest major road was divided into four categories: <100, 100-200, 201-300, and >300 m. Outcomes were parent-reported recurrent wheeze by age 3 years and asthma by age 5 years. Associations between residential proximity to major roads and respiratory outcomes were investigated using multivariable Cox proportional hazards modeling and logistic regression, adjusted for confounders. Out of 920 participants with home address data, pooled estimates identified 241 (26%) participants resided within 300 m of a major road, 296 (32%) developed recurrent wheeze by age 3, and 235 out of 858 participants (27%) developed asthma by 5 years. Participants who resided close to a major road had the highest risk of recurrent wheeze (adjusted hazards ratio for <100 m, 1.59, 95%CI: 1.08-2.33) and asthma (adjusted odds ratio for 201-300 m, 1.62, 95%CI: 1.16-2.25), compared to those residing >300 m from a major road. Proximity to major roads is associated with increased risks of recurrent wheeze and asthma in young children.

RESUMEN

We describe a cohort of 25 Iranian patients with infantile inflammatory bowel disease (IBD), 14 (56%) of whom had monogenic defects. After proper screening, patients were referred for whole exome sequencing (WES). Four patients had missense mutations in the IL10 RA, and one had a large deletion in the IL10 RB. Four patients had mutations in genes implicated in host:microbiome homeostasis, including TTC7A deficiency, and two patients with novel mutations in the TTC37 and NOX1. We found a novel homozygous mutation in the SRP54 in a deceased patient and the heterozygous variant in his sibling with a milder phenotype. Three patients had combined immunodeficiency: one with ZAP-70 deficiency (T+B+NK-), and two with atypical SCID due to mutations in RAG1 and LIG4. One patient had a G6PC3 mutation without neutropenia. Eleven of the 14 patients with monogenic defects were results of consanguinity and only 4 of them were alive to this date.

RESUMEN

Autophagy plays critical roles in the maintenance of endothelial cells in response to cellular stress caused by blood flow. There is growing evidence that both cell adhesion and cell detachment can modulate autophagy, but the mechanisms responsible for this regulation remain unclear. Immunoglobulin and proline-rich receptor-1 (IGPR-1) is a cell adhesion molecule that regulates angiogenesis and endothelial barrier function. In this study, using various biochemical and cellular assays, we demonstrate that IGPR-1 is activated by autophagy-inducing stimuli, such as amino acid starvation, nutrient deprivation, rapamycin, and lipopolysaccharide. Manipulating the IκB kinase ß activity coupled with in vivo and in vitro kinase assays demonstrated that IκB kinase ß is a key serine/threonine kinase activated by autophagy stimuli and that it catalyzes phosphorylation of IGPR-1 at Ser220 The subsequent activation of IGPR-1, in turn, stimulates phosphorylation of AMP-activated protein kinase, which leads to phosphorylation of the major pro-autophagy proteins ULK1 and Beclin-1 (BECN1), increased LC3-II levels, and accumulation of LC3 punctum. Thus, our data demonstrate that IGPR-1 is activated by autophagy-inducing stimuli and in response regulates autophagy, connecting cell adhesion to autophagy. These findings may have important significance for autophagy-driven pathologies such cardiovascular diseases and cancer and suggest that IGPR-1 may serve as a promising therapeutic target.

RESUMEN

BACKGROUND: Whole-genome sequencing (WGS) costs are falling, yet, outside oncology, this information is seldom used in adult clinics. We piloted a rapid WGS (rWGS) workflow, focusing initially on estimating power for a feasibility study of introducing genome information into acute cardiovascular care. METHODS: A prospective implementation study was conducted to test the feasibility and clinical utility of rWGS in acute cardiovascular care. rWGS was performed on 50 adult patients with acute cardiovascular events and cardiac arrest survivors, testing for primary and secondary disease-causing variants, cardiovascular-related pharmacogenomics, and carrier status for recessive diseases. The impact of returning rWGS results on short-term clinical care of participants was investigated. The utility of polygenic risk scores to stratify coronary artery disease was also assessed. RESULTS: Pathogenic variants, typically secondary findings, were identified in 20% (95% CI, 11.7-34.3). About 60% (95% CI, 46.2-72.4) of participants were carriers for one or more recessive traits, most commonly in HFE and SERPINA1 genes. Although 64% (95% CI, 50.1-75.9) of participants carried at least one pharmacogenetic variant of cardiovascular relevance, these were actionable in only 14% (95% CI, 7-26.2). Coronary artery disease prevalence among participants at the 95th percentile of polygenic risk score was 88.2% (95% CI, 71.8-95.7). CONCLUSIONS: We demonstrated the feasibility of rWGS integration into the inpatient management of adults with acute cardiovascular events. Our pilot identified pathogenic variants in one out of 5 acute vascular patients. Integrating rWGS in clinical care will progressively increase actionability.

RESUMEN

Chronic granulomatous disease is a non-prevalent genetic disorder due to different structural gene mutations encoding components of nicotinamide adenine dinucleotide phosphate oxidase complex. Nicotinamide adenine dinucleotide phosphate oxidase is a complex made by a group of five proteins (subunit) and plays an important role in the innate immune system. Five structural genes are responsible for encoding each subunit, in which cytochrome b-245 alpha chain (also known as p22-phox) is encoded by CYBA gene. CYBA gene mutation leads to a group of autosomal dominant chronic granulomatous disease. Decreased level or lack of nicotinamide adenine dinucleotide phosphate oxidase leaves affected individuals vulnerable to many types of infections and excessive inflammation. In this study, a family affected by BCGitis caused by a novel intronic autosomal recessive CYBA mutation (88,713,158 C > T) has been described. The proband is a 5-year-old girl with chronic granulomatous disease who was referred to the clinic due to BCGitis. The culprit mutation was detected following whole genome sequencing and was confirmed among the family members by Sanger sequencing. Being symptom-free at the time of diagnosis, despite the proband's mother homozygosity, was a characteristic feature of this report. Remarkably, none of the CYBA-mutated members, as a known chronic granulomatous disease causing gene, has expressed symptoms other than regional lymph node enlargements. This might explain the gene mutation site importance in demonstrating different manifestations.

RESUMEN

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) affects risks of type 2 diabetes (T2D), diabetes-related complications, and cardiovascular disease in a complex manner. This study is designed to clarify associations of sonographically-detected NAFLD and serum liver enzymes with diabetes-related microvascular complications. METHODS: A matched case-contorl study was designed for 440 patients with T2D and at least one of the chronic diabetes-related microvascular complications and 495 age- and gender-matched control patients with T2D. RESULTS: Considering pre-existing and newly developed chronic microvascular complications, diabetic peripheral neuropathy was found in 347 out of 935 (37.1%) study patients, diabetic retinopathy in 141/935 (15.1%), and diabetic nephropathy in 103/935 (11.0%). Diagnosis of diabetic retinopathy and diabetic nephropathy were inversely associated with the presence of NAFLD in the crude logistic regressions (OR [95% CI] = 0.18 [0.05-0.63], p value = 0.007; OR [95% CI] = 0.17 [0.04-0.59], p value = 0.011, respectively). The subgroup of NAFLD with elevated liver enzymes had lower odds of having diabetic peripheral neuropathy in the fully adjusted model (OR [95% CI] = 0.34 [0.12-0.98], p value = 0.048). CONCLUSION: Diagnosis of NAFLD with or without elevated serum liver enzymes was inversely correlated with certain chronic diabetes microvascular complications. Possible explanations for this counter-intuitive and unexpected finding are discussed and center on reverse-causality, wherein sicker patients may develop beneficial compensatory physiological and behavioral adaptations. Diversity of studied patients, in particular with regards to the ethnic and racial differences among the Western and Asian populations may also partly account for contrasting findings of the relationship between NAFLD and microvascular complications of diabetes.
