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.

Shinn JR, Wood CB, Colazo JM, Harrell FE, Rohde SL, Mannion K
(2018) Oral Oncol 87: 36-42
MeSH Terms: Aged, Female, Follow-Up Studies, Glossectomy, Humans, Incidence, Lymph Nodes, Lymphatic Metastasis, Male, Middle Aged, Neck, Neoplasm Invasiveness, Neoplasm Recurrence, Local, Neoplasm Staging, Retrospective Studies, Tongue, Tongue Neoplasms, Treatment Outcome
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.

Show Abstract · Added February 26, 2019
OBJECTIVES - To investigate the association between green tea intake and incident stones in two large prospective cohorts.
METHODS - We examined self-reported incident kidney stone risk in the Shanghai Men's Health Study (n = 58 054; baseline age 40-74 years) and the Shanghai Women's Health Study (n = 69 166; baseline age 40-70 years). Information on the stone history and tea intake was collected by in-person surveys. Multivariable Cox proportional hazards models were adjusted for baseline demographic variables, medical history and dietary intakes including non-tea oxalate from a validated food frequency questionnaire.
RESULTS - During 319 211 and 696 950 person-years of follow up, respectively, 1202 men and 1451 women reported incident stones. Approximately two-thirds of men and one-quarter of women were tea drinkers at baseline, of whom green tea was the primary type consumed (95% in men, 88% in women). Tea drinkers (men: hazard ratio 0.78, 95% confidence interval 0.69-0.88; women: hazard ratio 0.8, 95% confidence interval 0.77-0.98) and specifically green tea drinkers (men: hazard ratio 0.78, 95% confidence interval 0.69-0.88; women: hazard ratio 0.84, 95% confidence interval 0.74-0.95) had lower incident risk than never/former drinkers. Compared with never/former drinkers, a stronger dose-response trend was observed for the amount of dried tea leaf consumed/month by men (hazard ratio 0.67, 95% confidence interval 0.56-0.80, P  < 0.001) than by women (hazard ratio 0.87, 95% confidence interval 0.70-1.08, P  = 0.041).
CONCLUSIONS - Green tea intake is associated with a lower risk of incident kidney stones, and the benefit is observed more strongly among men.

Longer lactation duration is associated with decreased prevalence of non-alcoholic fatty liver disease in women.
Ajmera VH, Terrault NA, VanWagner LB, Sarkar M, Lewis CE, Carr JJ, Gunderson EP
(2019) J Hepatol 70: 126-132
MeSH Terms: Adolescent, Adult, Biomarkers, Blood Glucose, Breast Feeding, Disease Progression, Female, Follow-Up Studies, Humans, Insulin, Lactation, Non-alcoholic Fatty Liver Disease, Prevalence, Prognosis, Retrospective Studies, Risk Factors, Time Factors, Triglycerides, United States, Young Adult
Show Abstract · Added January 10, 2020
BACKGROUND & AIMS - Lactation lowers blood glucose and triglycerides, and increases insulin sensitivity. We hypothesized that a longer duration of lactation would be associated with lower prevalence of non-alcoholic fatty liver disease (NAFLD), which is the leading cause of chronic liver disease in the United States.
METHODS - Participants from the Coronary Artery Risk Development in Young Adults cohort study who delivered ≥ 1 child post-baseline (Y0: 1985-1986), and underwent CT quantification of hepatic steatosis 25 years following cohort entry (Y25: 2010-2011) were included (n = 844). The duration of lactation was summed for all post-baseline births, and NAFLD at Y25 was assessed by central review of CT images and defined by liver attenuation ≤ 40 Hounsfield Units after exclusion of other causes of hepatic steatosis. Unadjusted and multivariable logistic regression analyses were performed using an a priori set of confounding variables; age, race, education, and baseline body mass index.
RESULTS - Of 844 women who delivered after baseline (48% black, 52% white, mean age 49 years at Y25 exam), 32% reported lactation duration of 0 to 1 month, 25% reported >1 to 6 months, 43% reported more than 6 months, while 54 (6%) had NAFLD. Longer lactation duration was inversely associated with NAFLD in unadjusted logistic regression. For women who reported >6 months lactation compared to those reporting 0-1 month, the odds ratio for NAFLD was 0.48 (95% CI 0.25-0.94; p = 0.03) and the association remained after adjustment for confounders (adjusted odds ratio 0.46; 95% CI 0.22-0.97; p = 0.04).
CONCLUSIONS - A longer duration of lactation, particularly greater than 6 months, is associated with lower odds of NAFLD in mid-life and may represent a modifiable risk factor for NAFLD.
LAY SUMMARY - A longer duration of breastfeeding has been associated with multiple potential health benefits for the mother including reduction in heart disease, diabetes and certain cancers. In this study we found that breastfeeding for longer than 6 months was associated with a lower risk of non-alcoholic fatty liver disease in mid-life.

Utility of Routine Spirometry Measures for Surveillance of Idiopathic Subglottic Stenosis.
Carpenter DJ, Ferrante S, Bakos SR, Clary MS, Gelbard AH, Daniero JJ
(2019) JAMA Otolaryngol Head Neck Surg 145: 21-26
MeSH Terms: Adult, Aged, Disease Progression, Female, Follow-Up Studies, Humans, Laryngostenosis, Middle Aged, Peak Expiratory Flow Rate, Prognosis, Retrospective Studies, Sensitivity and Specificity, Spirometry
Show Abstract · Added July 30, 2020
Importance - Because of the recurrent nature of idiopathic subglottic stenosis, routine follow-up is necessary for monitoring progression of stenosis. However, no easily accessible, standardized objective measure exists to monitor disease progression.
Objective - To determine whether peak expiratory flow (PEF) can be used as a reliable and easily accessible biometric indicator of disease progression relative to other validated spirometry measures in patients with idiopathic subglottic stenosis.
Design, Setting, and Participants - Prospectively collected data on PEF, expiratory disproportion index (EDI), and total peak flow (TPF) from 42 women with idiopathic subglottic stenosis without comorbid lower airway or parenchymal lung disease who were treated at a single tertiary referral center between 2014 and 2018 were analyzed. The mean follow-up period was 18.2 months (range, 2-40 months). Ten patients initially screened were not included in the analysis owing to comorbid glottic or supraglottic stenosis or nonidiopathic etiology.
Main Outcomes and Measures - Measurements of PEF, EDI, and TPF were taken at preoperative visits and at all other visits.
Results - Forty-two women (mean age, 51.5 years; 98% white [n = 41]) met the inclusion criteria. The area under the curve for PEF was 0.855 (95% CI, 0.784-0.926). The optimal cutoff value was 4.4 liters per second (264 L/min), with a sensitivity and specificity of 84.4% and 82.0%, respectively. The area under the curve for EDI was 0.853 (95% CI, 0.782-0.925). For TPF, this was 0.836 (95% CI, 0.757-0.916).
Conclusions and Relevance - This study provides evidence supporting the use of PEF as a simple, efficient, and accessible way of monitoring progression of idiopathic subglottic stenosis and predicting receipt of surgical intervention. Sensitivity and specificity of PEF were comparable to those of the more complex measures of TPF and EDI.

Show Abstract · Added October 25, 2018
AIMS - We conducted a prospective study of emergency department (ED) patients with acute heart failure (AHF) to determine if worsening HF (WHF) could be predicted based on urinary electrolytes during the first 1-2 h of ED care. Loop diuretics are standard therapy for AHF patients. A subset of patients hospitalized for AHF will develop a blunted natriuretic response to loop diuretics, termed diuretic resistance, which often leads to WHF. Early detection of diuretic resistance could facilitate escalation of therapy and prevention of WHF.
METHODS AND RESULTS - Patients were eligible if they had an ED AHF diagnosis, had not yet received intravenous diuretics, had a systolic blood pressure > 90 mmHg, and were not on dialysis. Urine electrolytes and urine output were collected at 1, 2, 4, and 6 h after diuretic administration. Worsening HF was defined as clinically persistent or WHF requiring escalation of diuretics or administration of intravenous vasoactives after the ED stay. Of the 61 patients who qualified in this pilot study, there were 10 (16.3%) patients who fulfilled our definition of WHF. At 1 h after diuretic administration, patients who developed WHF were more likely to have low urinary sodium (9.5 vs. 43.0 mmol; P < 0.001) and decreased urine sodium concentration (48 vs. 80 mmol/L; P = 0.004) than patients without WHF. All patients with WHF had a total urine sodium of <35.4 mmol at 1 h (100% sensitivity and 60% specificity).
CONCLUSIONS - One hour after diuretic administration, a urine sodium excretion of <35.4 mmol was highly suggestive of the development of WHF. These relationships require further testing to determine if early intervention with alternative agents can prevent WHF.

Show Abstract · Added September 11, 2018
AIM - To evaluate the relationship of abdominal muscle lean tissue and adipose tissue volumes with prediabetes and diabetes.
RESEARCH DESIGN AND METHODS - We measured abdominal muscle composition in 3170 participants in the Coronary Artery Risk Development in Young Adults (CARDIA) study who underwent computed tomography (CT) at Year 25 of follow-up (ages, 43-55 years). Multinomial regression analysis was used to evaluate the associations of CT-measured intermuscular adipose tissue (IMAT), lean muscle tissue (lean) and visceral adipose tissue (VAT) volumes with diabetes at any point during the CARDIA study, newly detected prediabetes, prior history of prediabetes, and normal glucose tolerance. Models were adjusted for potential confounding factors: age, sex, race, height, smoking status, hypertension, hyperlipidaemia, cardiorespiratory fitness and study centre.
RESULTS - Higher IMAT, lean and VAT volumes were all separately associated with a higher prevalence of prediabetes and diabetes. Inclusion of VAT volume in models with both IMAT volume and lean volume attenuated the association of IMAT with both prediabetes and diabetes, but higher lean volume retained its association with prediabetes and diabetes. Individuals in the highest IMAT quartile, coupled with VAT in its lower three quartiles, had a higher prevalence of diabetes, but not of prediabetes, than those with both IMAT and VAT in their respective lower three quartiles. Adjusting for cardiorespiratory fitness did not substantially change the findings.
CONCLUSION - Higher IMAT volume was associated with a higher prevalence of diabetes even after adjustment for VAT volume. However, further study is warranted to understand the complicated relationship between abdominal muscle and adipose tissues.

Show Abstract · Added March 30, 2020
BACKGROUND & AIMS - Terbinafine is an antifungal agent that has been associated with rare instances of hepatotoxicity. In this study we aimed to describe the presenting features and outcomes of patients with terbinafine hepatotoxicity and to investigate the role of human leukocyte antigen (HLA)-A*33:01.
METHODS - Consecutive high causality cases of terbinafine hepatotoxicity enrolled into the Drug Induced Liver Injury Network were reviewed. DNA samples underwent high-resolution confirmatory HLA sequencing using the Ilumina MiSeq platform.
RESULTS - All 15 patients with terbinafine hepatotoxicity were more than 40 years old (median = 57 years), 53% were female and the median latency to onset was 38 days (range 24 to 114 days). At the onset of drug-induced liver injury, 80% were jaundiced, median serum alanine aminotransferase was 448 U/L and alkaline phosphatase was 333 U/L. One individual required liver transplantation for acute liver failure during follow-up, and 7 of the 13 (54%) remaining individuals had ongoing liver injury at 6 months, with 4 demonstrating persistently abnormal liver biochemistries at month 24. High-resolution HLA genotyping confirmed that 10 of the 11 (91%) European ancestry participants were carriers of the HLA-A*33:01, B*14:02, C*08:02 haplotype, which has a carrier frequency of 1.6% in European Ancestry population controls. One African American patient was also an HLA-A*33:01 carrier while 2 East Asian patients were carriers of a similar HLA type: A*33:03. Molecular docking studies indicated that terbinafine may interact with HLA-A*33:01 and A*33:03.
CONCLUSIONS - Patients with terbinafine hepatotoxicity most commonly present with a mixed or cholestatic liver injury profile and frequently have residual evidence of chronic cholestatic injury. A strong genetic association of HLA-A*33:01 with terbinafine drug-induced liver injury was confirmed amongst Caucasians.
LAY SUMMARY - A locus in the human leukocyte antigen gene (HLA-A*33:01, B*14:02, C*08:02) was significantly overrepresented in Caucasian and African American patients with liver injury attributed to the antifungal medication, terbinafine. These data along with the molecular docking studies demonstrate that this genetic polymorphism is a plausible risk factor for developing terbinafine hepatotoxicity and could be used in the future to help doctors make a diagnosis more rapidly and confidently.

Antibody responses to subspecies (SGG) proteins, especially pilus protein Gallo2178, have been consistently associated with colorectal cancer risk. Previous case-control studies and prospective studies with up to 8 years of follow-up, however, were unable to decipher the temporality of antibody responses to SGG in the context of the long-term multistep development of colorectal cancer. In this study, we analyzed a large U.S. colorectal cancer cohort consortium with follow-up beyond 10 years for antibody responses to SGG. We applied multiplex serology to measure antibody responses to 9 SGG proteins in participants of 10 prospective U.S. cohorts (CLUE, CPSII, HPFS, MEC, NHS, NYUWHS, PHS, PLCO, SCCS, and WHI) including 4,063 incident colorectal cancer cases and 4,063 matched controls. Conditional logistic regression was used to assess whether antibody responses to SGG were associated with colorectal cancer risk, overall and by time between blood draw and diagnosis. Colorectal cancer risk was increased among those with antibody responses to Gallo2178, albeit not statistically significant [OR, 1.23; 95% confidence interval (CI), 0.99-1.52]. This association was stronger for cases diagnosed <10 years after blood draw (OR, 1.40; 95% CI, 1.09-1.79), but was not found among cases diagnosed ≥10 years after blood draw (OR, 0.79; 95% CI, 0.50-1.24). In a large cohort consortium, we reproduced the association of antibody responses to SGG Gallo2178 with colorectal cancer risk for individuals diagnosed within 10 years after blood draw. This timing-specific finding suggests that antibody responses to SGG are associated with increased colorectal cancer risk only after tumorigenesis has begun. .

Background Epilepsy is a common complication of pediatric stroke. Aim In this study, we aim to measure the association between epilepsy and neurologic outcome after childhood arterial ischemic stroke. Methods Prospective cohort study of children (29 days-19 years) enrolled after an acute arterial ischemic stroke at 21 international pediatric stroke centers and followed to identify epilepsy. One year post-stroke, outcomes were scored using the examination-based Pediatric Stroke Outcome Measure (range = 0-10); higher values reflect greater disability. Ordinal logistic regression was used to measure the association of Pediatric Stroke Outcome Measure scores (categorized as 0-1, 1.5-3, 3.5-6, 6.5-10) with epilepsy. Results Investigators enrolled 86 children (median age = 6.1 years, interquartile range (IQR) = 1.4-12.2 years) with acute stroke. At 1 year, 18/80 (23%) remained on an anticonvulsant including 8/80 (10%) with epilepsy. Among the 70 with Pediatric Stroke Outcome Measure scored, the median was 0.5 (IQR = 0-1.5) for children without epilepsy ( n = 63), and 6 (IQR = 0.5-10) for children with epilepsy ( n = 7). In univariable analyses, poorer 1-year outcome was associated with middle cerebral artery stroke, cortical infarcts, hemorrhagic transformation, hospital disposition not to home, and epilepsy. In multivariable analysis, middle cerebral artery stroke (odds ratio (OR) = 4.9, 95% confidence intervals (CI) = 1.1-21.3) and epilepsy (OR = 24.1, CI = 1.5-380) remained associated with poorer outcome. Conclusions Children who developed epilepsy during the first year post-stroke had poorer neurologic outcomes than those without epilepsy.
