Show Abstract · Added March 3, 2020
OBJECTIVE - Eosinophilic oesophagitis (EoO) and IBD are immune-mediated diseases of the gastrointestinal tract with possible overlapping pathogenic mechanisms. Our aim was to define the epidemiology and clinical implications of concurrent EoO and IBD diagnoses.
DESIGN - We conducted a prospective cohort analysis using the Truven MarketScan database (2009-2016) to estimate the incidence and prevalence of EoO in patients with Crohn's disease (CD) or UC and vice versa. Cox proportional hazards and Kaplan-Meier methods were used to estimate the risk of EoO-related or IBD-related complications among patients with concurrent diagnoses.
RESULTS - Among 134 013 536 individuals, the incidence of EoO, CD and UC were 23.1, 51.2 and 55.2 per 100 000 person-years, respectively. The risk of EoO was higher among patients with CD (incidence rate ratio [IRR] 5.4, p<0.01; prevalence ratio (PR) 7.8, p<0.01) or UC (IRR 3.5, p<0.01; PR 5.0, p<0.01), while the risk of IBD was higher among patients with EoO (CD: IRR 5.7, p<0.01; PR 7.6, p<0.01; UC: IRR 3.4, p<0.01; PR 4.9, p<0.01) versus individuals without either diagnosis. Concurrent diagnosis of EoO and IBD was associated with greater composite risk of IBD-related complications (CD: adjusted HR (aHR) 1.09, p=0.01; UC: aHR 1.10, p=0.04) but lower composite risk of EoO-related complications (aHR 0.59; p<0.01).
CONCLUSION - Based on a population-based prospective cohort analysis, the risk of EoO is significantly higher among patients with IBD and vice versa. Concurrent diagnoses might modify the risk of IBD-related and EoO-related complications. Studies defining the mechanisms underlying these observations are needed.

Hematologic Complications of Immune Checkpoint Inhibitors.
Davis EJ, Salem JE, Young A, Green JR, Ferrell PB, Ancell KK, Lebrun-Vignes B, Moslehi JJ, Johnson DB
(2019) Oncologist 24: 584-588
MeSH Terms: Adult, Adverse Drug Reaction Reporting Systems, Aged, Aged, 80 and over, Antibodies, Monoclonal, Humanized, Antineoplastic Agents, Immunological, B7-H1 Antigen, Databases, Factual, Female, Hematologic Diseases, Humans, Incidence, Ipilimumab, Male, Middle Aged, Neoplasms, Pharmacovigilance, Programmed Cell Death 1 Receptor, Risk Factors
Show Abstract · Added November 12, 2019
Immune checkpoint inhibitors have improved outcomes for patients with numerous hematological and solid cancers. Hematologic toxicities have been described, but the spectrum, timing, and clinical presentation of these complications are not well understood. We used the World Health Organization's pharmacovigilance database of individual-case-safety-reports (ICSRs) of adverse drug reactions, VigiBase, to identify cases of hematologic toxicities complicating immune checkpoint inhibitor therapy. We identified 168 ICSRs of immune thrombocytopenic purpura (ITP), hemolytic anemia (HA), hemophagocytic lymphohistiocytosis, aplastic anemia, and pure red cell aplasia in 164 ICSRs. ITP ( = 68) and HA ( = 57) were the most common of these toxicities and occurred concomitantly in four patients. These events occurred early on treatment (median 40 days) and were associated with fatal outcome in 12% of cases. Ipilimumab-based therapy (monotherapy or combination with anti-programmed death-1 [PD-1]) was associated with earlier onset (median 23 vs. 47.5 days,  = .006) than anti-PD-1/programmed death ligand-1 monotherapy. Reporting of hematologic toxicities has increased over the past 2 years (98 cases between January 2017 and March 2018 vs. 70 cases before 2017), possibly because of increased use of checkpoint inhibitors and improved recognition of toxicities. Future studies should evaluate incidence of hematologic toxicities, elucidate risk factors, and determine the most effective treatment algorithms. KEY POINTS: Immune-mediated hematologic toxicities are a potential side effect of immune checkpoint inhibitors (ICIs).Providers should monitor complete blood counts during treatment with ICIs.Corticosteroids are the mainstay of treatment for immune-mediated hematologic toxicities.Further research is needed to define patient-specific risk factors and optimal management strategies for hematologic toxicities.

Sex-based differences in the incidence of inflammatory bowel diseases-pooled analysis of population-based studies from the Asia-Pacific region.
Shah SC, Khalili H, Chen CY, Ahn HS, Ng SC, Burisch J, Colombel JF
(2019) Aliment Pharmacol Ther 49: 904-911
MeSH Terms: Adolescent, Adult, Aged, Asia, Child, Child, Preschool, Cohort Studies, Female, Humans, Incidence, Infant, Infant, Newborn, Inflammatory Bowel Diseases, Male, Middle Aged, Pacific Ocean, Population Surveillance, Risk Factors, Sex Characteristics, Young Adult
Show Abstract · Added March 3, 2020
BACKGROUND - There appear to be differences in risk factor profiles for IBD between Asia-Pacific and Western populations, which might suggest idiosyncrasies in pathogenesis. Recently, sex-based differences in IBD according to the age of diagnosis have been described in Western populations.
AIM - To identify whether sex-based differences in IBD incidence similarly exist across the age spectrum for Asia-Pacific populations.
METHODS - We identified Asia-Pacific population-based cohorts where IBD incidence data stratified by sex were available for the full age spectrum. Cohorts were included only if IBD diagnoses were confirmed and validated. We calculated incidence rate ratios of Crohn's disease (CD) and ulcerative colitis (UC) according to age and compared differences between males and females using random-effects meta-analysis.
RESULTS - Among 567.8 million people from 11 Asia-Pacific countries/provinces/nations, we identified 10 553 incident CD cases (7060 males; 3493 females) and 16 946 incident UC cases (9754 males; 7192 females). Starting in early adolescence until age 50 years, there was a 36%-64% higher incidence of CD in males vs females (P < 0.001). UC incidence ranged from 20%-42% higher in males vs females in the age groups between 15 and 65 years (P < 0.05).
CONCLUSIONS - In a pooled analysis of population-based studies from the Asia-Pacific region, we found a male predominance of both CD and UC for the majority of the age spectrum from adolescence to middle/late-middle age. Additional studies are needed to clarify biological and nonbiological determinants of sex differences in IBD, which might be distinct between Asia-Pacific and Western populations.

Show Abstract · Added April 3, 2019
Background While prior studies have linked the neighborhood environment and development of subclinical atherosclerosis, it is unknown whether living in neighborhoods with greater availability of "unhealthy" food outlets (fast-food chain restaurants and convenience stores) is associated with risk of developing coronary artery calcification ( CAC ). Methods and Results We included 2706 CARDIA study (Coronary Artery Risk Development in Young Adults) participants who underwent CAC measurement during follow-up years 15 (2000-2001), 20 (2005-2006), and 25 (2010-2011). Neighborhood features examined included percentage of all food outlets that were convenience stores and fast-food chain restaurants within a 3-km Euclidean buffer distance from each participant's residence. Econometric fixed effects models, which by design control for all time-invariant covariates, were used to model the longitudinal association between simultaneous within-person change in percentage food outlet and change in CAC . At baseline (year 15), 9.7% of participants had prevalent CAC . During 10 years of follow-up, 21.1% of participants developed CAC . Each 1-SD increase in percentage of convenience stores was associated with a 1.34 higher odds of developing CAC (95% CI : 1.04, 1.72) after adjusting for individual- and neighborhood-level covariates; however, there was no significant association between increased percentage of fast-food chain restaurants and developing CAC (odds ratio=1.15; 95% CI : 0.96, 1.38). There were no significant associations between increases in either food outlet percentage and progression of CAC . Conclusions Our findings suggest that increases in the relative availability of convenience stores in participants' neighborhoods is related to the development of CAC over time.

Incidence and malignancy rates of indeterminate pediatric thyroid nodules.
Wang H, Mehrad M, Ely KA, Liang J, Solórzano CC, Neblett WW, Coogan AC, Weiss VL
(2019) Cancer Cytopathol 127: 231-239
MeSH Terms: Adenocarcinoma, Follicular, Adolescent, Adult, Child, Child, Preschool, Female, Follow-Up Studies, Humans, Incidence, Male, Prognosis, Retrospective Studies, Tennessee, Thyroid Neoplasms, Thyroid Nodule, Thyroidectomy, Young Adult
Show Abstract · Added April 15, 2019
BACKGROUND - The American Thyroid Association guidelines task force currently recommends definitive thyroidectomy or lobectomy after an indeterminate thyroid biopsy in children. This recommendation is based on evidence of a greater incidence and a higher risk of malignancy compared with adults in earlier pediatric studies. Such management may lead to overtreatment and unnecessary surgery for many children in the United States.
METHODS - The objective of the current study was to re-evaluate pediatric thyroid nodules and assess the overall percentages and malignancy rates for indeterminate thyroid biopsies in children. In total, 302 pediatric thyroid fine-needle aspirations (FNAs) were analyzed retrospectively (2001-2018). Distribution percentages and malignancy rates were calculated for each category of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC).
RESULTS - Two indeterminate TBSRTC groups (atypia of undetermined significance/follicular lesion of undetermined significance and follicular neoplasm/suspicious for a follicular neoplasm) had much lower distribution percentages and malignancy rates compared with earlier pediatric series and American Thyroid Association guidelines. A meta-analysis further supported these findings and demonstrated distinctly different malignancy rates for the indeterminate groups (atypia of undetermined significance/follicular lesion of undetermined significance, follicular neoplasm/suspicious for a follicular neoplasm, and suspicious for malignancy), suggesting the need for TBSRTC category-specific management recommendations rather than a nondiscriminatory, up-front surgical approach.
CONCLUSIONS - Adult patients with indeterminate preoperative thyroid cytopathology are followed by repeat biopsy and possibly molecular testing before undergoing definitive surgery. However, in children, the guidelines are considerably more aggressive and recommend definitive surgery after the first indeterminate thyroid biopsy. Here, the largest pediatric cohort to date with meta-analysis is presented, and the authors propose a re-evaluation of this up-front approach to pediatric thyroid care.

MeSH Terms: Adolescent, American Heart Association, Association, Brain Ischemia, Child, Child, Preschool, Humans, Incidence, Infant, Infant, Newborn, Pediatrics, Stroke, United States
Show Abstract · Added March 24, 2020
Purpose- Much has transpired since the last scientific statement on pediatric stroke was published 10 years ago. Although stroke has long been recognized as an adult health problem causing substantial morbidity and mortality, it is also an important cause of acquired brain injury in young patients, occurring most commonly in the neonate and throughout childhood. This scientific statement represents a synthesis of data and a consensus of the leading experts in childhood cardiovascular disease and stroke. Methods- Members of the writing group were appointed by the American Heart Association Stroke Council's Scientific Statement Oversight Committee and the American Heart Association's Manuscript Oversight Committee and were chosen to reflect the expertise of the subject matter. The writers used systematic literature reviews, references to published clinical and epidemiology studies, morbidity and mortality reports, clinical and public health guidelines, authoritative statements, personal files, and expert opinion to summarize existing evidence and to indicate gaps in current knowledge. This scientific statement is based on expert consensus considerations for clinical practice. Results- Annualized pediatric stroke incidence rates, including both neonatal and later childhood stroke and both ischemic and hemorrhagic stroke, range from 3 to 25 per 100 000 children in developed countries. Newborns have the highest risk ratio: 1 in 4000 live births. Stroke is a clinical syndrome. Delays in diagnosis are common in both perinatal and childhood stroke but for different reasons. To develop new strategies for prevention and treatment, disease processes and risk factors that lead to pediatric stroke are discussed here to aid the clinician in rapid diagnosis and treatment. The many important differences that affect the pathophysiology and treatment of childhood stroke are discussed in each section. Conclusions- Here we provide updates on perinatal and childhood stroke with a focus on the subtypes, including arterial ischemic, venous thrombotic, and hemorrhagic stroke, and updates in regard to areas of childhood stroke that have not received close attention such as sickle cell disease. Each section is highlighted with considerations for clinical practice, attendant controversies, and knowledge gaps. This statement provides the practicing provider with much-needed updated information in this field.

Show Abstract · Added March 20, 2020
BACKGROUND - Incidence of oral tongue squamous cell carcinoma (OTC) is rising among those under age 50 years. The etiology is unknown.
METHODS - A total of 395 cases of OTC diagnosed and/or treated at Vanderbilt University Medical Center between 2000 and 2017 were identified. Of those, 113 (28.6%) were early onset (age < 50 years). Logistic regression was used to identify factors associated with early onset OTC. Cox proportional hazards models evaluated survival and recurrence.
RESULTS - Compared to typical onset patients, patients with early onset OTC were more likely to receive multimodality treatment (surgery and radiation; adjusted odds ratio [aOR], 2.7; 95% confidence interval [CI], 1.2-6.3) and report a history of snuff use (aOR, 5.4; 95% CI, 1.8-15.8) and were less likely to report a history of cigarette use (aOR, 0.5; 95% CI, 0.2-0.9). Early onset patients had better overall survival (adjusted hazard ratio, 0.6).
CONCLUSIONS - This is the largest study to evaluate factors associated with early onset OTC and the first to report an association with snuff.

Show Abstract · Added November 7, 2019
OBJECTIVE - To determine if there is a critical depth of invasion that predicts micrometastasis in early oral tongue cancer.
METHODS - Retrospective series identifying patients undergoing primary surgical resection of T1 or T2 oral tongue cancer who elected against neck treatment between 2000 and 2015. Cox proportional-hazard model compared the relative hazard and cumulative incidence of recurrence to depth of invasion. The model used a 2 parameter quadratic effect for depth that was chosen based on Akaike's information criterion.
RESULTS - Ninety-three patients were identified with T1 or T2 oral tongue squamous cell carcinoma and clinically N0 neck undergoing glossectomy without elective neck treatment. 61% were male and median age was 60 years. Median follow up was 45 months, and 76 patients had at least two years of follow up. Thirty-six of 76 patients recurred (47.4%), with 15 recurring in the oral cavity (19.7%) and 21 developing nodal metastasis (27.6%). Cox proportional-hazards quadratic polynomial showed increasing hazard of recurrence with depth of invasion and the cumulative incidence increased sharply within the range of data from 2 to 6 mm depth of invasion.
CONCLUSIONS - Depth of invasion is significantly associated with nodal metastasis and has been added to the 8th AJCC staging guidelines. Variable depths of invasion have been associated with regional metastasis; however, there is likely not a critical depth that predicts neck recurrence due to progressive hazards and cumulative risk of occult metastasis. The risk of regional metastasis is likely much greater than previously believed and increases progressively with increasing depth.

(2018) Oral Oncol 87: 1-7
MeSH Terms: Age of Onset, Humans, Incidence, Prognosis, Risk Factors, Survival Analysis, Tobacco, Smokeless, Tongue Neoplasms, United States
Show Abstract · Added March 20, 2020
The incidence of early onset oral tongue squamous cell carcinoma (OTC) has been increasing in the United States, and no clear etiology has been identified. Studies on this topic have generally been small and presented varied results. The goal of this review is to analyze and synthesize the literature regarding early onset OTC risk factors, outcomes, and molecular analyses within the US. To date, studies suggest that early onset OTC patients tend to have less heavy cigarette use than typical onset patients, but there may be an association between early onset OTC and smokeless tobacco (chewing tobacco and snuff) use. Early onset OTC is associated with similar or possibly improved survival compared to typical onset OTC. There has been no evidence to support a significant role for human papillomavirus in development of early onset OTC. Further research with larger cohorts of these patients is needed to better characterize this disease entity.

Show Abstract · Added December 13, 2018
Ibrutinib, a Bruton tyrosine kinase inhibitor, is approved for treatment of various B-cell malignancies. In ibrutinib clinical studies, low-grade haemorrhage was common, whereas major haemorrhage (MH) was infrequent. We analysed the incidence of and risk factors for MH from 15 ibrutinib clinical studies (N = 1768), including 4 randomised controlled trials (RCTs). Rates of any-grade bleeding were similar for single-agent ibrutinib and ibrutinib combinations (39% and 40%). Low-grade bleeding was more common in ibrutinib-treated than comparator-treated patients (35% and 15%), and early low-grade bleeding was not associated with MH. The proportion of MH in RCTs was higher with ibrutinib than comparators (4.4% vs. 2.8%), but after adjusting for longer exposure with ibrutinib (median 13 months vs. 6 months), the incidence of MH was similar (3.2 vs. 3.1 per 1000 person-months). MH led to treatment discontinuation in 1% of all ibrutinib-treated patients. Use of anticoagulants and/or antiplatelets (AC/AP) during the study was common (~50% of patients) and had an increased exposure-adjusted relative risk for MH in both the total ibrutinib-treated population (1.9; 95% confidence interval, 1.2-3.0) and RCT comparator-treated patients (2.4; 95% confidence interval, 1.0-5.6), indicating that ibrutinib may not alter the effect of AC/AP on the risk of MH in B-cell malignancies.
