RESUMO
BACKGROUND: Given the significant exposures experienced by the World Trade Center (WTC) general responders, there is increasing interest in understanding the effect of these exposures on aging in this population. We aim to identify factors that may be associated with frailty, a clinical syndrome characterized by a decrease in one's reserve that has been linked to poor health outcomes. METHODS: WTC general responders enrolled in the WTC Health Program aged 50 and older provided informed consent. Validated frailty assessments, the Frailty Phenotype (with the Johns Hopkins Frailty Assessment Calculator) along with the FRAIL scale, categorized nonfrail from prefrail/frail. Fall risk, functional status, and cognition were also assessed. WTC variables, including an identified WTC-certified condition, were utilized. The risk of frailty was estimated using log binomial regression analysis. A 95% confidence interval (CI) was used to estimate the prevalence ratio (PR). RESULTS: One hundred and six participants were included; 38 (35.8%) were classified as pre-frail or frail. More of the pre-frail/frail group were obese (57.9% vs. 25%; p = 0.004) and had a WTC-certified condition (78.9% vs. 58.8%; p = 0.036). Obesity (PR = 2.43, 95% CI = 1.31, 4.53), a WTC-certified condition (PR = 1.77, 95% CI = 1.09, 2.89), and risk of falling (PR = 1.97, 95% CI = 1.01, 3.84) were independently associated with frailty. CONCLUSIONS: Obesity and having a WTC-certified condition were found to be risk factors for frailty in our pilot study. Future work may focus on further identifying risk factors for frailty in the larger WTC general responder population.

BACKGROUND: Scalp psoriasis is common and difficult to treat. OBJECTIVE: To evaluate efficacy and safety of tildrakizumab for the treatment of scalp psoriasis. METHODS: In this Phase 3b, randomized, double-blind, placebo (PBO)-controlled study (NCT03897088), patients with moderate-to-severe plaque psoriasis affecting the scalp (Investigator Global Assessment modified [IGA mod] 2011 [scalp] ≥3, Psoriasis Scalp Severity Index [PSSI] ≥12, ≥30% scalp surface area affected) received tildrakizumab 100 mg or PBO at W0 and W4. The primary endpoint was IGA mod 2011 (scalp) score of "clear" or "almost clear" with ≥2-point reduction from baseline at W16 (IGA mod 2011 [scalp] response). Key secondary endpoints were PSSI 90 response at W12 and W16 and IGA mod 2011 (scalp) response at W12. Safety was assessed from adverse events. RESULTS: Of patients treated with tildrakizumab (n = 89) vs PBO (n = 82), 49.4% vs 7.3% achieved IGA mod 2011 (scalp) response at W16 (primary endpoint) and 46.1% vs 4.9% at W12; 60.7% vs 4.9% achieved PSSI 90 response at W16 and 48.3% vs 2.4% at W12 (all P < .00001). No serious treatment-related adverse events occurred. LIMITATIONS: Only short-term data are presented. CONCLUSION: Tildrakizumab was efficacious for the treatment of scalp psoriasis with no new safety signals.

BACKGROUND: The risk of hepatitis C virus (HCV) infection among emergency responders exposed to human remains, blood/bodily fluids, and/or sewage is unknown. Methods: A cross-sectional study of 3871 World Trade Center General Responder Cohort (WTCGRC) members followed at the Icahn School of Medicine at Mount Sinai, born from 1945-1965, and recruited from 2016-2018 were tested for HCV infection, and prevalence was compared to National Health and Nutrition Examination Survey data from 2003 to 2012. A nested case-control study compared 61 HCV antibody positive cases to 2571 controls. Multivariable logistic regression models adjusting for time of birth, traditional HCV risk factors, and type of work at the World Trade Center (WTC) site, determined if contact with human remains, blood/bodily fluids, and/or sewage at the WTC site was associated with HCV infection. Results: The age-standardized point prevalence of HCV infection among WTCGRC members was 2.98% [95% CI (2.39, 3.56)] and in the US population was 3.33% [95% CI (2.54, 4.11)] [% difference = 0.35%, 95% CI (- 0.31%, 1.01%), P=0.47]. In separate multivariable models, adjusting for possible confounders, contact with human remains was not associated with HCV infection [OR = 1.10, 95%CI(0.63, 1.91), P = 0.74)], contact with blood and/or bodily fluids was not associated with HCV infection [OR = 1.45, 95%CI(0.82, 2.56), P = 0.20], and contact with sewage was significantly associated with HCV infection [OR = 1.72, 95%CI(1.00, 2.98), P = 0.05]. Conclusion: Contact with sewage may increase the risk of HCV infection.

Background & Aims: The prevalence and aetiology of liver fibrosis vary over time and impact racial/ethnic groups unevenly. This study measured time trends and identified factors associated with advanced liver fibrosis in the United States. Methods: Standardised methods were used to analyse data on 47,422 participants (≥20 years old) in the National Health and Nutrition Examination Survey (1999-2018). Advanced liver fibrosis was defined as Fibrosis-4 ≥2.67 and/or Forns index ≥6.9 and elevated alanine aminotransferase. Results: The estimated number of people with advanced liver fibrosis increased from 1.3 million (95% CI 0.8-1.9) to 3.5 million (95% CI 2.8-4.2), a nearly threefold increase. Prevalence was higher in non-Hispanic Black and Mexican American persons than in non-Hispanic White persons. In multivariable logistic regression analysis, cadmium was an independent risk factor in all racial/ethnic groups. Smoking and current excessive alcohol use were risk factors in most. Importantly, compared with non-Hispanic White persons, non-Hispanic Black persons had a distinctive set of risk factors that included poverty (odds ratio [OR] 2.09; 95% CI 1.44-3.03) and susceptibility to lead exposure (OR 3.25; 95% CI 1.95-5.43) but did not include diabetes (OR 0.88; 95% CI 0.61-1.27; p =0.52). Non-Hispanic Black persons were more likely to have high exposure to lead, cadmium, polychlorinated biphenyls, and poverty than non-Hispanic White persons. Conclusions: The number of people with advanced liver fibrosis has increased, creating a need to expand the liver care workforce. The risk factors for advanced fibrosis vary by race/ethnicity. These differences provide useful information for designing screening programmes. Poverty and toxic exposures were associated with the high prevalence of advanced liver fibrosis in non-Hispanic Black persons and need to be addressed. Impact and Implications: Because liver disease often produces few warning signs, simple and inexpensive screening tests that can be performed by non-specialists are needed to allow timely diagnosis and linkage to care. This study shows that non-Hispanic Black persons have a distinctive set of risk factors that need to be taken into account when designing liver disease screening programs. Exposure to exogenous toxins may be especially important risk factors for advanced liver fibrosis in non-Hispanic Black persons.
RESUMO
BACKGROUND: Suicidal ideation (SI) is an early risk factor for suicide among disaster responders. To date, however, no known study has examined the prevalence, and pre-, peri-, and post-disaster risk correlates of SI in World Trade Center (WTC) responders, one of the largest disaster response populations in U.S. METHODS: The prevalence, and pre-, peri- and post-event correlates of SI were assessed in a population-based health monitoring cohort of 14,314 police responders and 16,389 non-traditional responders (e.g., construction workers) who engaged in response, recovery, and clean-up efforts following the 9/11/2001 terrorist attacks on the WTC. Multivariable analyses were conducted to identify correlates and individual psychiatric symptoms associated with SI in each group. RESULTS: A total 12.5% of non-traditional and 2.2% of police WTC responders reported SI. Depression, functional impairment, alcohol use problems, and lower family support while working at the WTC site were associated with SI in both groups of responders. Symptom-level analyses revealed that three symptoms accounted for approximately half of the variance in SI for both groups-feeling bad about oneself, or that one has let down oneself or family; feeling down, depressed, or hopeless; and sense of foreshortened future (44.7% in non-traditional and 71% in police). LIMITATIONS: Use of self-report measures and potentially limited generalizability. CONCLUSIONS: SI is prevalent in WTC disaster responders, particularly non-traditional responders. Post-9/11 psychiatric symptoms reflecting guilt, shame, hopelessness, and associated functional impairment are most strongly linked to SI, suggesting that interventions targeting these factors may help mitigate suicide risk in this population.

Despite experiencing a significant trauma, only a subset of World Trade Center (WTC) rescue and recovery workers developed posttraumatic stress disorder (PTSD). Identification of biomarkers is critical to the development of targeted interventions for treating disaster responders and potentially preventing the development of PTSD in this population. Analysis of gene expression from these individuals can help in identifying biomarkers of PTSD. We established a well-phenotyped sample of 371 WTC responders, recruited from a longitudinal WTC responder cohort using stratified random sampling, by obtaining blood, self-reported and clinical interview data. Using bulk RNA-sequencing from whole blood, we examined the association between gene expression and WTC-related PTSD symptom severity on (i) highest lifetime Clinician-Administered PTSD Scale (CAPS) score, (ii) past-month CAPS score, and (iii) PTSD symptom dimensions using a 5-factor model of re-experiencing, avoidance, emotional numbing, dysphoric arousal and anxious arousal symptoms. We corrected for sex, age, genotype-derived principal components and surrogate variables. Finally, we performed a meta-analysis with existing PTSD studies (total N = 1016), using case/control status as the predictor and correcting for these variables. We identified 66 genes significantly associated with total highest lifetime CAPS score (FDR-corrected p < 0.05), and 31 genes associated with total past-month CAPS score. Our more granular analyses of PTSD symptom dimensions identified additional genes that did not reach statistical significance in our analyses with total CAPS scores. In particular, we identified 82 genes significantly associated with lifetime anxious arousal symptoms. Several genes significantly associated with multiple PTSD symptom dimensions and total lifetime CAPS score (SERPINA1, RPS6KA1, and STAT3) have been previously associated with PTSD. Geneset enrichment of these findings has identified pathways significant in metabolism, immune signaling, other psychiatric disorders, neurological signaling, and cellular structure. Our meta-analysis revealed 10 genes that reached genome-wide significance, all of which were downregulated in cases compared to controls (CIRBP, TMSB10, FCGRT, CLIC1, RPS6KB2, HNRNPUL1, ALDOA, NACA, ZNF429 and COPE). Additionally, cellular deconvolution highlighted an enrichment in CD4 T cells and eosinophils in responders with PTSD compared to controls. The distinction in significant genes between total lifetime CAPS score and the anxious arousal symptom dimension of PTSD highlights a potential biological difference in the mechanism underlying the heterogeneity of the PTSD phenotype. Future studies should be clear about methods used to analyze PTSD status, as phenotypes based on PTSD symptom dimensions may yield different gene sets than combined CAPS score analysis. Potential biomarkers implicated from our meta-analysis may help improve therapeutic target development for PTSD.

BACKGROUND: The World Trade Center (WTC) general responder cohort (GRC) was exposed to environmental toxins possibly associated with increased risk of developing autoimmune conditions. OBJECTIVES: Two study designs were used to assess incidence and risks of autoimmune conditions in the GRC. METHODS: Three clinically trained professionals established the status of possible GRC cases of autoimmune disorders adhering to diagnostic criteria, supplemented, as needed, by specialists' review of consenting responders' medical records. Nested case-control analyses using conditional logistic regression estimated the risk associated with high WTC exposure (being in the 9/11/2001 dust cloud or ≥median days' response worked) compared with low WTC exposure (all other GRC members'). Four controls were matched to each case on age at case diagnosis (±2 years), sex, race/ethnicity, and year of program enrollment. Sex-specific and sensitivity analyses were performed. GRC age- and sex-adjusted standardized incidence ratios (SIRs) were compared with the Rochester Epidemiology Project (REP). Complete REP inpatient and outpatient medical records were reviewed by specialists. Conditions meeting standardized criteria on ≥2 visits were classified as REP confirmed cases. RESULTS: Six hundred and twenty-eight responders were diagnosed with autoimmune conditions between 2002 and 2017. In the nested case-control analyses, high WTC exposure was not associated with autoimmune domains and conditions (rheumatologic domain odds ratio [OR] = 1.03, 95% confidence interval [CI] = 0.77, 1.37; rheumatoid arthritis OR = 1.12, 95% CI = 0.70, 1.77). GRC members had lower SIR than REP. Women's risks were generally greater than men's. CONCLUSIONS: The study found no statistically significant increased risk of autoimmune conditions with WTC exposures.

OBJECTIVE: This study evaluated race/ethnic differences in the prevalence and correlates of World Trade Center (WTC) related posttraumatic stress disorder (PTSD) in WTC responders. METHOD: Data were analyzed from a population-based, health monitoring cohort of 15,440 nontraditional (i.e., construction workers) and 13,403 police WTC responders. RESULTS: Among nontraditional responders, the prevalence of WTC-related PTSD was highest in Latino/a (40.4%) versus Black (27.3%) and White (26.5%) responders; among police responders, Latino/a (10.4%) responders also had higher prevalence of PTSD relative to Black (9.8%) and White (8.7%) responders. However, multivariable analyses revealed that prior psychiatric diagnosis, greater severity of WTC-related exposures, post-9/11 stressful life events, (in police responders only) older age, and (in nontraditional responders only) lower income and education levels accounted for substantially higher prevalence of WTC-related PTSD across ethnic/racial groups. Additionally, among nontraditional responders, subgroups with added risk included responders who were: Latino/a or White had high post-911 stressful events; Latino/a or Black and had pre-9/11 psychiatric history; and Latinas. Among police responders, subgroups with added risk were Latino/a or Black police with a low annual income. CONCLUSIONS: Collectively, results of this study underscore the burden of differential vulnerability that can contribute to higher prevalence of PTSD in certain cultural subgroups following large magnitude traumatic events.

BACKGROUND: The World Trade Center (WTC) attack exposed thousands of workers to toxic chemicals that have been linked to liver diseases and cancers. This study examined the relationship between the intensity of WTC dust exposure and the risk of hepatic steatosis in the WTC General Responders Cohort (GRC). METHODS: All low-dose computed tomography (CT) scans of the chest performed on the WTC GRC between September 11, 2001 and December 31, 2018, collected as part of the World Trade Center Health Program, were reviewed. WTC dust exposure was categorized into five groups based on WTC arrival time. CT liver density was estimated using an automated algorithm, statistics-based liver density estimation from imaging. The relationship between the intensity of WTC dust exposure and the risk of hepatic steatosis was examined using univariate and multivariable regression analyses. RESULTS: Of the 1788 WTC responders, 258 (14.4%) had liver attenuation less than 40 Hounsfield units (HU < 40) on their earliest CT. Median time after September 11, 2001 and the earliest available CT was 11.3 years (interquartile range: 8.0-14.9 years). Prevalence of liver attenuation less than 40 HU was 17.0% for arrivals on September 11, 2001, 16.0% for arrivals on (September 12, 2001 or September 13, 2001), 10.9% for arrivals on September 14-30, 2001, and 9.0% for arrivals on January 10, 2001 or later (p = 0.0015). A statistically significant trend of increasing liver steatosis was observed with earlier arrival times (p < 0.0001). WTC arrival time remained a significant independent factor for decreased liver attenuation after controlling for other covariates. CONCLUSIONS: Early arrival at the WTC site was significantly associated with increasing hepatic steatosis.

Objectives: To develop and validate a clinical frailty index to characterize aging among responders to the 9/11 World Trade Center (WTC) attacks. Methods: This study was conducted on health monitoring data on a sample of 6197 responders. A clinical frailty index, WTC FI-Clinical, was developed according to the cumulative deficit model of frailty. The validity of the resulting index was assessed using all-cause mortality as an endpoint. Its association with various cohort characteristics was evaluated. Results: The sample's median age was 51 years. Thirty items were selected for inclusion in the index. It showed a strong correlation with age, as well as significant adjusted associations with mortality, 9/11 exposure severity, sex, race, pre-9/11 occupation, education, and smoking status. Discussion: The WTC FI-Clinical highlights effects of certain risk factors on aging within the 9/11 responder cohort. It will serve as a useful instrument for monitoring and tracking frailty within this cohort.

PURPOSE: The World Trade Center (WTC) attack of September 11, 2001 created an unprecedented environmental exposure to known and suspected carcinogens. High incidence of multiple myeloma and precursor conditions has been reported among first responders to the WTC disaster. To expand on our prior screening studies, and to characterize the genomic impact of the exposure to known and potential carcinogens in the WTC debris, we were motivated to perform whole-genome sequencing (WGS) of WTC first responders and recovery workers who developed a plasma cell disorder after the attack. EXPERIMENTAL DESIGN: We performed WGS of nine CD138-positive bone marrow mononuclear samples from patients who were diagnosed with plasma cell disorders after the WTC disaster. RESULTS: No significant differences were observed in comparing the post-WTC driver and mutational signature landscapes with 110 previously published WGSs from 56 patients with multiple myeloma and the CoMMpass WGS cohort (n = 752). Leveraging constant activity of the single-base substitution mutational signatures 1 and 5 over time, we estimated that tumor-initiating chromosomal gains were windowed to both pre- and post-WTC exposure. CONCLUSIONS: Although limitations in sample size preclude any definitive conclusions, our findings suggest that the observed increased incidence of plasma cell neoplasms in this population is due to complex and heterogeneous effects of the WTC exposure that may have initiated or contributed to progression of malignancy.

BACKGROUND: Over 90,000 rescue and recovery responders to the September 2001 World Trade Center (WTC) attacks were exposed to toxic materials that can impair cardiac function and increase cardiovascular disease (CVD) risk. We examined WTC-related exposures association with annual and cumulative CVD incidence and risk over 17 years in the WTC Health Program (HP) General Responder Cohort (GRC). METHODS: Post 9/11 first occurrence of CVD was assessed in 37,725 responders from self-reported physician diagnosis of, or current treatment for, coronary artery disease, myocardial infarction, stroke and/or congestive heart failure from WTCHP GRC monitoring visits. Kaplan-Meier estimates of CVD incidence used the generalized Wilcoxon test statistic to account for censored data. Cox proportional hazards regression analyses estimated the CVD hazard ratio associated with 9/11/2001 arrival in responders with and without dust cloud exposure, compared with arrival on or after 9/12/2001. Additional analyses adjusted for comorbidities. RESULTS: To date, 6.3% reported new CVD. In covariate-adjusted analyses, men's CVD 9/11/2001 arrival risks were 1.40 (95% confidence interval [CI] = 1.26, 1.56) and 1.43 (95% CI = 1.29, 1.58) and women's were 2.16 (95% CI = 1.49, 3.11) and 1.59 (95% CI = 1.11, 2.27) with and without dust cloud exposure, respectively. Protective service employment on 9/11 had higher CVD risk. CONCLUSIONS: WTCHP GRC members with 9/11/2001 exposures had substantially higher CVD risk than those initiating work afterward, consistent with observations among WTC-exposed New York City firefighters. Women's risk was greater than that of men's. GRC-elevated CVD risk may also be occurring at a younger age than in the general population.

BACKGROUND: Nearly 20 years after the terrorist attacks of September 11, 2001, multiple studies have documented the adverse mental consequences among World Trade Center (WTC) rescue, recovery, and clean-up workers. However, scarce research has examined mental health stigma and barriers to care in WTC-exposed individuals, and no known study has examined whether rates of endorsement may differ between police and "nontraditional" responders, the latter comprising a heterogeneous group of workers and volunteers. OBJECTIVE: To identify the prevalence and correlates of mental health stigma and barriers to care in WTC responders. METHODS: Mental health stigma and barriers to care and their correlates were examined in 6,777 police and 6,272 nontraditional WTC responders. RESULTS: Nontraditional responders endorsed more stigma or barriers to care concerns than police responders. Within a subsample who screened positive for a psychiatric disorder, police were more likely than nontraditional responders to endorse "concerns that negative job consequences might result" (17.9% vs. 9.1%), while nontraditional responders were more likely to endorse "I don't know where to go to find counseling services" (18.4% vs.6.6%). Within this subsample, mental health service need and more severe WTC-related posttraumatic stress disorder symptoms were associated with increased likelihood of endorsing stigma or barriers; pre-9/11 psychiatric history and non-Hispanic Black race/ethnicity were associated with lower likelihood of endorsing stigma or barriers. CONCLUSIONS: Results of this study underscore the burden of mental health stigma and barriers to care in WTC responders, and highlight the need for targeted interventions to address these concerns and promote mental healthcare utilization in this population.

Objective: Research examining the responders of the World Trade Center terrorist attacks of 9/11 has found that Hispanic responders are at greater risk for posttraumatic stress disorder (PTSD) than non-Hispanic White responders. However, no studies have examined how acculturation may influence the relationship between coping and PTSD in Hispanic 9/11 responders. This novel study is the first to examine differences in coping and PTSD among Hispanic responders by level of acculturation. Methods: The sample is composed of 845 Hispanic 9/11 responders who were seen at the World Trade Center Health Program and participated in a web-based survey. Using logistic and multiple linear regression, we examined how acculturation is related to their coping strategies and risk for PTSD. We also tested for interaction to examine whether level of acculturation moderated the relationship between coping and PTSD symptom severity. Results: Key findings revealed that higher acculturation is associated with the use of substances, venting, and humor to cope, while lower acculturation is associated with the use of active coping and self-distraction in this sample. We also found that less acculturated responders were more likely to experience more severe PTSD. Lastly, our findings revealed that Hispanics who are more acculturated and used substances to cope had more severe PTSD than less acculturated responders. Conclusion: These findings highlight the need to consider the role of acculturation in Hispanic responders' coping and PTSD. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Objective: To assess the reliability of a questionnaire designed to reconstruct risk factors for head and neck cancer relative to the 9/11 World Trade Center (WTC) response and over the lifetime. Methods: As part of a nested case-control study, 200 WTC Health Program (WTCHP) General Responder Cohort (GRC) members completed a newly-developed study questionnaire via telephone (with a trained interviewer) or online (self-administered). We assessed agreement between measures of tobacco and alcohol use in our questionnaire results and data collected previously during WTCHP-GRC monitoring visits using Cohens Kappa (κ) and intraclass correlation coefficient (ICC) for categorical and continuous measures, respectively. We compared agreement by disease status, survey mode, and year of WTCHP enrollment. Results: We observed high agreement between measures of lifetime, pre-WTC, and post-WTC smoking prevalence (all κ > 0.85) and smoking duration (all ICC > 0.84). There was moderate agreement between measures of smoking frequency (ICC: 0.61-0.73). Agreement between measures of smoking frequency, but not duration, differed by disease status, and agreement between smoking measures was higher for participants who completed our survey by phone than by web. Among cases, there were no differences based on enrollment in the WTCHP before or after diagnosis. Conclusion: Agreement between measures was generally high, although potential reporting bias and a mode effect that should be considered when interpreting analyses of self-reported data in this population; however differential misclassification appears to be minimal. Our questionnaire may be useful for future studies examining similar behavioral risk factors among disaster-exposed populations.

BACKGROUND: Following the September 11, 2001, attacks on the World Trade Center (WTC), thousands of workers were exposed to an array of toxins known to cause adverse health effects, including cancer. This study evaluates cancer incidence in the WTC Health Program General Responder Cohort occurring within 12 years post exposure. METHODS: The study population consisted of 28 729 members of the General Responder Cohort enrolled from cohort inception, July 2002 to December 31, 2013. Standardized incidence ratios (SIRs) were calculated with cancer case inclusion and follow-up starting post September 11, 2001 (unrestricted) and, alternatively, to account for selection bias, with case inclusion and follow-up starting 6 months after enrollment in the WTC Health Program (restricted). Case ascertainment was based on linkage with six state cancer registries. Under the restricted criterion, hazard ratios were estimated using multivariable Cox proportional hazards models for all cancer sites combined and for prostate cancer. RESULTS: Restricted analyses identified 1072 cancers in 999 responders, with elevations in cancer incidence for all cancer sites combined (SIR = 1.09, 95% confidence interval [CI] = 1.02 to 1.16), prostate cancer (SIR = 1.25, 95% CI = 1.11 to 1.40), thyroid cancer (SIR = 2.19, 95% CI = 1.71 to 2.75), and leukemia (SIR = 1.41, 95% CI = 1.01 to 1.92). Cancer incidence was not associated with any WTC exposure index (composite or individual) for all cancer sites combined or for prostate cancer. CONCLUSION: Our analyses show statistically significant elevations in cancer incidence for all cancer sites combined and for prostate and thyroid cancers and leukemia. Multivariable analyses show no association with magnitude or type of exposure.
RESUMO
OBJECTIVE: To characterize the prevalence, risk and protective correlates, and clinical characteristics associated with probable subthreshold posttraumatic stress disorder (PTSD) in police and nontraditional (eg, construction workers) World Trade Center (WTC) responders a median of 12.2 years after September 11, 2001. METHODS: A total of 4,196 WTC responders, monitored via the WTC Health Program, completed a web-based survey between 2012 and 2014 assessing a range of variables, including demographics, WTC exposures, medical and psychiatric comorbidities, and mental health services use. The sample included 2,029 police responders and 2,167 nontraditional responders. Current (past-month) probable WTC-related PTSD level (none, subthreshold, or full PTSD) was assessed based on DSM-IV criteria using the PTSD Checklist-Specific Stressor version (PCL-S). RESULTS: The prevalence of current probable full and subthreshold WTC-related PTSD in police responders was 9.3% and 17.5%, respectively, and in nontraditional responders was 21.9% and 24.1%, respectively. Risk and protective correlates for subthreshold PTSD included post-9/11 medical comorbidities and traumatic events (odds ratios [ORs] = 1.1-1.2). Clinical characteristics included elevated rates of comorbid depression (OR = 3.2 and 3.9 for subthreshold PTSD and 17.2 and 30.3 for full PTSD for nontraditional and police responders, respectively). Among responders with subthreshold PTSD, police were more likely to have accessed mental health services and utilized a greater variety of treatments than nontraditional responders. CONCLUSIONS: Overall, 26.8% of police and 46.0% of nontraditional responders met criteria for probable WTC-related full or subthreshold PTSD an average of 12 years after 9/11. Probable subthreshold PTSD, which is not typically assessed in clinical settings, was more prevalent than probable full PTSD and was associated with significantly elevated rates of psychiatric comorbidities, functional impairment, and reduced quality of life. These findings underscore the importance of assessing, monitoring, and possibly treating subthreshold PTSD in WTC and other disaster responders.

BACKGROUND AND AIMS: To determine the prevalence of moderate-to-severe hepatic steatosis (HS) and associated risk factors in members of the World Trade Center (WTC) General Responder Cohort (GRC) who qualify for low-dose non-contrast computed tomography for lung cancer screening and compare them to non-WTC participants in the same screening program. METHODS: All participants gave written informed consent before participating in this IRB-approved study. Clinical variables and laboratory values were recorded. Hepatic attenuation measurement (Hounsfield unit; HU) was measured on low-dose computed tomography (LDCT) and a threshold attenuation value <40HU indicated moderate-to-severe HS. Bivariate and multivariable linear and logistic regression analyses were performed. Propensity scores (PS) were calculated and inverse probability weighting (IPW) was used to adjust for potential confounders when comparing the WTC with non-WTC participants. RESULTS: The prevalence of moderate-to-severe HS was 16.2% among 154 WTC participants compared to 5.3% among 170 non-WTC participants. In WTC members, moderate-to-severe HS was associated with higher BMI, higher laboratory liver function tests, and former smoking status. Using PS analysis and IPW to account for potential confounders, the odds ratio for moderate-to-severe HS was 3.4-fold higher (95% confidence interval: 1.7-6.7) in the WTC participants compared with non-WTC participants. Moderate-to-severe HS was also associated with higher BMI and former smoker status. CONCLUSION: Prevalence of moderate-to-severe HS was >3-fold higher in the WTC-GRC group than in other participants.

PURPOSE: Develop and validate an automated method for measuring liver attenuation in non-contrast low-dose chest CT (LDCT) scans and compare it to the standard manual method for identifying moderate-to-severe hepatic steatosis (HS). METHOD: The automated method identifies a region below the right lung within the liver and uses statistical sampling techniques to exclude non-liver parenchyma. The method was used to assess moderate-to-severe HS on two IRB-approved cohorts: 1) 24 patients with liver disease examined between 1/2013-1/2017 with non-contrast chest CT and abdominal MRI scans obtained within three months of liver biopsy, and 2) 319 lung screening participants with baseline LDCT performed between 8/2011-1/2017. Agreement between the manual and automated CT methods, the manual MRI method, and pathology for determining moderate-to-severe HS was assessed using Cohen's Kappa by applying a 40 HU threshold to the CT method and 17.4% fat fraction to MRI. Agreement between the manual and automated CT methods was assessed using the intraclass correlation coefficient (ICC). Variability was assessed using Bland-Altman limits of agreement (LoA). RESULTS: In the first cohort, the manual and automated CT methods had almost perfect agreement (ICCâ¯=â¯0.97, κâ¯=â¯1.00) with LoA of -7.6 to 4.7 HU. Both manual and automated CT methods had almost perfect agreement with MRI (κâ¯=â¯0.90) and substantial agreement with pathology (κâ¯=â¯0.77). In the second cohort, the manual and automated CT methods had almost perfect agreement (ICCâ¯=â¯0.94, κâ¯=â¯0.87). LoA were -10.6 to 5.2 HU. CONCLUSION: Automated measurements of liver attenuation from LDCT scans can be used to identify moderate-to-severe HS on LDCT.
