RESUMEN
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: 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.

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 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: 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.

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.

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.

Nearly two decades after the 9/11 attacks on the World Trade Center (WTC), the prevalence of mental disorders remains elevated among traditional (e.g., police) and non-traditional (e.g., construction workers) responders who were involved in the WTC rescue, recovery, and clean-up efforts. To date, however, scarce research has examined factors associated with perceived need for mental health care, which is critical to promoting engagement in mental health treatment in this population. Data were analyzed from 16,170 WTC responders, including 8881 police responders and 7289 non-traditional responders, who completed their first annual health monitoring visit with the WTC Health Program an average of 6.5 years after September 11, 2001. Predisposing, enabling, and need-based factors associated with perceived need for mental health care were examined using multivariable logistic regression analyses. Nearly half (48.7%) of non-traditional responders and a fifth (20.6%) of police responders reported a need for mental health care. The most common perceived needs were for psychotropic medication, individual psychotherapy, and stress management counseling. Predisposing (e.g., female gender) and need-based factors (e.g., WTC-related posttraumatic stress disorder) predicted perceived need for mental health care in both groups. Among non-traditional responders, Hispanic ethnicity and current suicidal ideation were additionally associated with this outcome. Non-traditional WTC responders are substantially more likely than police WTC responders to perceive a need for mental health treatment. Characterization of factors associated with perceived need for treatment can help inform population-based outreach and monitoring efforts designed to promote engagement in mental health treatment in WTC responders.

The World Trade Center (WTC) attacks exposed rescue and recovery workers to a complex mix of toxicants, including carcinogens. our study compared site-specific cancer incidence of head and neck cancers (HNC) from 2003 through 2012 among 33,809 consented WTC General Responder Cohort (GRC) members to the New Jersey State Cancer Registry, using standardized incidence ratios (SIRs). HNC grouped using SEER ICD-O-3 codes into HPV-related (oropharyngeal) and non-related (other oral-nasal; laryngeal) tumors based on anatomical site. For the 73 GRC members identified with HNC, proportional hazard regression assessed the relationship between WTC exposure and other socio-demographic characteristics. An overall excess of HNC was not observed (SIR = 1.00, 95% CI: 0.78, 1.25) but excess cancer was seen in the latest observation period (2009-2012: SIR = 1.4; 95% CI: 1.01, 1.89). A similar temporal pattern was seen for HPV-related oropharyngeal cancer and laryngeal cancer, but not for non-HPV-related sites (oral-nasal cancer). HNC was significantly associated with increasing age (8% per year, 95% CI: 5%, 12%), non-Hispanic white ethnic group-ethnicity (hazard ratio (HR) = 3.51, 95 CI: 1.49, 8.27); there was a borderline association with the 9/11 occupation of military/protective services vs. others (HR = 1.83 95% CI: 0.99, 3.38; p = 0.0504). Caution is needed in interpreting these results given the small number of cases, potential for surveillance bias, and long latency for most cancers. Our findings highlight the need to examine the potentially carcinogenic effects of WTC exposure in the context of other strong risk factors, and the need for continued medical monitoring of WTC responders.

BACKGROUND: Asthma is a major source of morbidity among World Trade Center (WTC) rescue and recovery workers. While physical and mental health comorbidities have been associated with poor asthma control, the potential role and determinants of adherence to self-management behaviors (SMB) among WTC rescue and recovery workers is unknown. OBJECTIVES: To identify modifiable determinants of adherence to asthma self-management behaviors in WTC rescue and recovery worker that could be potential targets for future interventions. METHODS: We enrolled a cohort of 381 WTC rescue and recovery workers with asthma. Sociodemographic data and asthma history were collected during in-person interviews. Based on the framework of the Model of Self-regulation, we measured beliefs about asthma and controller medications. Outcomes included medication adherence, inhaler technique, use of action plans, and trigger avoidance. RESULTS: Medication adherence, adequate inhaler technique, use of action plans, and trigger avoidance were reported by 44%, 78%, 83%, and 47% of participants, respectively. Adjusted analyses showed that WTC rescue and recovery workers who believe that they had asthma all the time (odds ratio [OR]: 2.37; 95% confidence interval [CI]: 1.38-4.08), that WTC-related asthma is more severe (OR: 1.73; 95% CI: 1.02-2.93), that medications are important (OR: 12.76; 95% CI: 5.51-29.53), and that present health depends on medications (OR: 2.39; 95% CI: 1.39-4.13) were more likely to be adherent to their asthma medications. Illness beliefs were also associated with higher adherence to other SMB. CONCLUSIONS: Low adherence to SMB likely contributes to uncontrolled asthma in WTC rescue and recovery workers. Specific modifiable beliefs about asthma chronicity, the importance of controller medications, and the severity of WTC-related asthma are independent predictors of SMB in this population. Cognitive behavioral interventions targeting these beliefs may improve asthma self-management and outcomes in WTC rescue and recovery workers. Key message: This study identified modifiable beliefs associated with low adherence to self-management behaviors among World Trade Center rescue and recovery rescue and recovery workers with asthma which could be the target for future interventions. CAPSULE SUMMARY: Improving World Trade Center-related asthma outcomes will require multifactorial approaches such as supporting adherence to controller medications and other self-management behaviors. This study identified several modifiable beliefs that may be the target of future efforts to support self-management in this patient population.

OBJECTIVES: Head and neck cancers (HNCs) may be among the health consequences of involvement in the World Trade Center (WTC) response on and after 11 September 2001. We conducted a nested case-control study of WTC Health Program (WTCHP) general responders to examine the effects of WTC exposures and behavioural risk factors on HNC. METHODS: We enrolled 64 cases and 136 controls, matched on age, sex and race/ethnicity within risk sets. We assessed tobacco and alcohol use, sexual activity, and occupational exposures prior to, during and after WTC exposure until case diagnosis via questionnaire. We obtained WTC exposure information (duration (first to last day), total days and location of work) from the WTCHP General Responder Data Center. We assessed associations with HNC, and interaction among exposures, using conditional logistic regression. RESULTS: Responders in protective services versus other occupations had increased odds (OR: 2.51, 95% CI 1.09 to 5.82) of HNC. Among those in non-protective services occupations, arriving to the WTC effort on versus after 11 September 2001 was significantly associated with HNC (OR: 3.77, 95% CI 1.00 to 14.11). Duration of work was not significantly associated with HNC. Lifetime and post-WTC years of cigarette smoking and post-WTC number of sex partners were positively and significantly associated with HNC, while alcohol consumption was not. CONCLUSIONS: These findings suggest opportunities for HNC risk factor mitigation (eg, smoking cessation, human papillomavirus vaccination) and contribute to a risk factor profile which may assist WTCHP clinicians with identifying high-risk responders and improve detection and treatment outcomes in this population.

BACKGROUND: Multiple comorbidities have been reported among rescue/recovery workers responding to the 9/11/2001 WTC disaster. In this study, we developed an index that quantifies the cumulative physiological burden of comorbidities and predicts life expectancy in this cohort. METHODS: A machine learning approach (gradient boosting) was used to model the relationship between mortality and several clinical parameters (laboratory test results, blood pressure, pulmonary function measures). This model was used to construct a risk index, which was validated by assessing its association with a number of health outcomes within the WTC general responder cohort. RESULTS: The risk index showed significant associations with mortality, self-assessed physical health, and onset of multiple chronic conditions, particularly COPD, hypertension, asthma, and sleep apnea. CONCLUSION: As an aggregate of several clinical parameters, this index serves as a cumulative measure of physiological dysregulation and could be utilized as a prognostic indicator of life expectancy and morbidity risk.

BACKGROUND: We investigated trans-generational associations between Post Traumatic Stress Disorder (PTSD) symptoms in World Trade Center (WTC) responders and behavioral problems in their children. METHODS: Participants were WTC responders-8034 police and 8352 non-traditional (eg, construction workers)-with one or more children at the time of their first visit to the World Trade Center Health Program (WTC-HP). Self-report questionnaires were administered approximately 4 years after the 9/11 WTC attack. RESULTS: A total of 31.4% of non-traditional and 20.0% of police responders reported behavioral problems in their children. Non-traditional responder status, female sex, Hispanic ethnicity, more life stressors, more WTC-related PTSD symptoms, and dysphoric arousal symptoms were significant correlates of behavioral problems in responders' children. CONCLUSIONS: Specific parental sociodemographic, psychosocial and clinical characteristics, as well as PTSD symptom severity, were significant correlates of child behavior problems. Findings encourage monitoring and early intervention for children of disaster responders, particularly those at highest risk.

BACKGROUND: The disasters at Seveso, Three Mile Island, Bhopal, Chernobyl, the World Trade Center (WTC) and Fukushima had historic health and economic sequelae for large populations of workers, responders and community members. METHODS: Comparative data from these events were collected to derive indications for future preparedness. Information from the primary sources and a literature review addressed: i) exposure assessment; ii) exposed populations; iii) health surveillance; iv) follow-up and research outputs; v) observed physical and mental health effects; vi) treatment and benefits; and vii) outreach activities. RESULTS: Exposure assessment was conducted in Seveso, Chernobyl and Fukushima, although none benefited from a timely or systematic strategy, yielding immediate and sequential measurements after the disaster. Identification of exposed subjects was overall underestimated. Health surveillance, treatment and follow-up research were implemented in Seveso, Chernobyl, Fukushima, and at the WTC, mostly focusing on the workers and responders, and to a lesser extent on residents. Exposure-related physical and mental health consequences were identified, indicating the need for a long-term health care of the affected populations. Fukushima has generated the largest scientific output so far, followed by the WTCHP and Chernobyl. Benefits programs and active outreach figured prominently in only the WTC Health Program. The analysis of these programs yielded the following lessons: 1) Know who was there; 2) Have public health input to the disaster response; 3) Collect health and needs data rapidly; 4) Take care of the affected; 5) Emergency preparedness; 6) Data driven, needs assessment, advocacy. CONCLUSIONS: Given the long-lasting health consequences of natural and man-made disasters, health surveillance and treatment programs are critical for management of health conditions, and emergency preparedness plans are needed to prevent or minimize the impact of future threats.

BACKGROUND: Rescue and recovery workers responding to the 2001 collapse of the World Trade Center (WTC) sustained exposures to toxic chemicals and have elevated rates of multiple morbidities. METHODS: Using data from the World Trade Center Health Program and the National Death Index for 2002-2011, we examined standardized mortality ratios (SMR) and proportional cancer mortality ratios (PCMR) with indirect standardization for age, sex, race, and calendar year to the U.S. general population, as well as associations between WTC-related environmental exposures and all-cause mortality. RESULTS: We identified 330 deaths among 28,918 responders (SMR 0.43, 95%CI 0.39-0.48). No cause-specific SMRs were meaningfully elevated. PCMRs were elevated for neoplasms of lymphatic and hematopoietic tissue (PCMR 1.76, 95%CI 1.06-2.75). Mortality hazard ratios showed no linear trend with exposure. CONCLUSIONS: Consistent with a healthy worker effect, all-cause mortality among responders was not elevated. There was no clear association between intensity and duration of exposure and mortality. Surveillance is needed to monitor the proportionally higher cancer mortality attributed to lymphatic/hematopoietic neoplasms.

BACKGROUND: Asthma and gastroesophageal reflux disease (GERD) are two common conditions among the responders to the WTC attacks. This study examined whether the cumulative incidence rates of asthma and GERD differed by sex among 24,022 and 23,557 WTC responders, respectively. METHODS: Cox proportional hazards regression was used to examine the sex difference in the rate of onset of physician-diagnosed asthma or GERD, from 9/12/2001 through 12/31/2015. RESULTS: The cumulative incidence of asthma reached 23% for women and 17% for men by the end of 2015, and the cumulative incidence of GERD reached 45% for women and 38% for men. Comparing women to men, the hazard ratio was 1.48 (95% confidence interval (CI): 1.27, 1.74) for asthma, and 1.25 (95% CI: 1.13, 1.38) for GERD. CONCLUSIONS: WTC general responders have a substantial burden of asthma and GERD, with higher incidence in women. Am. J. Ind. Med. 59:815-822, 2016. © 2016 Wiley Periodicals, Inc.

PURPOSE: The current study examined the role of World Trade Center (WTC) disaster exposure (hours spent working on the site, dust cloud exposure, and losing friend/loved one) in exacerbating the effects of post-disaster life stress on posttraumatic stress disorder (PTSD) symptoms and overall functioning among WTC responders. METHOD: Participants were 18,896 responders (8466 police officers and 10,430 non-traditional responders) participating in the WTC Health Program who completed an initial examination between July, 2002 and April, 2010 and were reassessed an average of two years later. RESULTS: Among police responders, there was a significant interaction, such that the effect of post-disaster life stress on later PTSD symptoms and overall functioning was stronger among police responders who had greater WTC disaster exposure (ß's=.029 and .054, respectively, for PTSD symptoms and overall functioning). This moderating effect was absent in non-traditional responders. Across both groups, post-disaster life stress also consistently was related to the dependent variables in a more robust manner than WTC exposure. DISCUSSION: The present findings suggest that WTC exposure may compound post-disaster life stress, thereby resulting in a more chronic course of PTSD symptoms and reduced functioning among police responders.

PURPOSE: The current longitudinal study examined posttraumatic stress disorder (PTSD) symptom severity in relation to smoking abstinence and reduction over time among responders to the World Trade Center (WTC) disaster. METHOD: Participants were 763 police and 1881 non-traditional (e.g., construction workers) WTC responders who reported being smokers at an initial examination obtained between July 2002 and July 2011 at the WTC Health Program (WTC-HP). WTC responders were reassessed, on average, 2.5 years later. RESULTS: For police WTC responders, higher levels of WTC-related PTSD symptoms at the initial visit were associated with a decreased likelihood of smoking abstinence (OR=0.98, p=.002) and with decreased smoking reduction (ß=-.06, p=.012) at the follow-up visit. WTC-related PTSD symptom severity was not related to likelihood of smoking abstinence or change in number of cigarettes smoked among non-traditional responders. Post hoc analyses suggested that for police, hyperarousal PTSD symptoms were predictive of decreased abstinence likelihood at the follow-up visit (OR=0.56, p=.006). DISCUSSION: The present findings suggest that PTSD symptoms may be differentially related to smoking behavior among police and non-traditional WTC responders in a naturalistic, longitudinal investigation. Future work may benefit from exploring further which aspects of PTSD (as compared to each other and to common variance) explain smoking maintenance.
