Objectives/Hypothesis Establish treatment patterns and economic burden in US patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) versus without chronic rhinosinusitis (CRS). Determine comparative costs of subgroups with high clinical burden. Study Design Observational, retrospective, case-control study. Methods This study matched patients with CRSwNP to patients without CRS (1:1) using the Truven Health MarketScan US claims database. Categorical and continuous variables were compared using McNemar test and paired t test (normal distribution) or Wilcoxon signed rank tests (non-normal distribution). Within subgroups, chi(2) and Wilcoxon or t tests were used (normal distribution). Results There were 10,841 patients with CRSwNP and 10,841 patients without CRS included. Mean age in the CRSwNP cohort was 45.8 years; 56.2% were male. During follow-up, patients with CRSwNP had an increased diagnosis of asthma versus patients without CRS (20.8% vs. 8.1%, respectively; P < .001). Annual incremental costs were $11,507 higher for patients with CRSwNP versus those without CRS. Costs were higher in subgroups of patients with CRSwNP undergoing functional endoscopy sinus surgery (FESS), with a comorbid diagnosis of asthma, receiving oral corticosteroids, or macrolides versus the overall CRSwNP group. Patients with CRSwNP undergoing FESS had the highest costs of the four subgroups ($26,724, $22,456, $20,695, and $20,990, respectively). Conclusions Annual incremental costs were higher among patients with CRSwNP versus without CRS. Patients with CRSwNP with high clinical burden had higher overall costs than CRSwNP patients without.

Data on health care resource utilization (HCRU) and costs for patients with atopic dermatitis (AD) are lacking.The objective of this study was to determine HCRU and costs associated with AD in US adults.This retrospective study identified patients with AD from the Truven Health Marketscan Commercial Claims and Encounters database during 2013 based on ≥2 claims with International Classification of Diseases, Ninth Revision code 691.8 (n = 10,533; first claim = index event); 1-year continuous enrollment before and after index was required. Patients were age- and gender-matched in a 1:3 ratio to controls without AD (n = 31,599). Patients with AD were further categorized into 2 groups, with treatment regimens as surrogates for increasing disease severity: claim for phototherapy or systemic immunomodulatory agents (more severe) or no claim for either (less severe). Incremental differences in resource use and costs were evaluated using multivariate analysis.AD was associated with higher utilization and costs across resource categories (all P.0001); adjusted total incremental annual costs were $3,302. Resource utilization and costs were higher in the more severe group, with adjusted total incremental annual costs of $4,463.AD is associated with significant incremental health care utilization and costs, which are higher in patients with more severe disease.

Rationale: In a phase 2b trial (NCT01854047), dupilumab (DPL) improved lung function and reduced severe exacerbations. This sub-analysis estimated severe exacerbation-related direct medical and productivity-related costs. Methods: Uncontrolled persistent asthma pts on medium-to-high-dose ICS/LABA were randomized to 24 weeks of add-on therapy with DPL 200mg every 2 weeks (q2w), 300mg q2w, 200mg every 4 weeks (q4w), 300mg q4w, or placebo (PBO). Healthcare resource utilization, work and non-work related days lost were collected using a questionnaire and monetized using published costs. Results are presented for the q2w and PBO groups only; q2w regimens have been selected for dosing in a phase 3 trial. Results: Compared with PBO, both DPL groups had lower numbers of hospitalizations, inpatient days, unscheduled physician visits, as well as work and non-work-related days lost. The 300mg group had lower number of emergency room visits while the 200mg group was similar to PBO. Total direct medical and productivity-related costs were lower for the DPL groups (Table). Severe exacerbation-related costs were 52% and 84% lower, respectively, in the DPL q2w groups vs PBO. Most common adverse events with DPL vs PBO were upper respiratory tract infection (13–15% vs 18%) and injection-site erythema (14–22% vs 8%). Conclusions: Dupilumab-treated patients had lower severe exacerbation-related costs compared to PBO.

Objectives Male breast cancer is a rare disease of largely unknown aetiology. In addition to genetic and hormone-related risk factors, a large number of environmental chemicals are suspected of playing a role in breast cancer. The identification of occupations or occupational exposures associated with an increased incidence of breast cancer in men may help to identify mammary carcinogens in the environment. Methods Occupational risk factors for male breast cancer were investigated in a multi-centre case-control study conducted in eight European countries which included 104 cases and 1901 controls. Lifetime work history was obtained during in-person interviews. Occupational exposures to endocrine disrupting chemicals (alkylphenolic compounds, phthalates, polychlorinated biphenyls and dioxins) were assessed on a case-by-case basis using expert judgement. Results Male breast cancer incidence was particularly increased in motor vehicle mechanics (OR 2.1, 95% CI 1.0 to 4.4) with a dose-effect relationship with duration of employment. It was also increased in paper makers and painters, forestry and logging workers, health and social workers, and furniture manufacture workers. The OR for exposure to alkylphenolic compounds above the median was 3.8 (95% CI 1.5 to 9.5). This association persisted after adjustment for occupational exposures to other environmental oestrogens. Conclusion These findings suggest that some environmental chemicals are possible mammary carcinogens. Petrol, organic petroleum solvents or polycyclic aromatic hydrocarbons are suspect because of the consistent elevated risk of male breast cancer observed in motor vehicle mechanics. Endocrine disruptors such as alkylphenolic compounds may play a role in breast cancer.

OBJECTIVE: To evaluate the potential association between occupational exposure to chlorinated and petroleum solvents and mycosis fungoides (MF).METHODS: A questionnaire on lifetime job history was administered to 100 patients diagnosed with MF and 2846 controls. Odds ratios (ORs) were calculated as the measure of the association between exposure to each specific solvent and MF.RESULTS: In the total sample and in men, cases and controls did not differ in relation to exposure to any of the solvents studied. In women, an association with MF was seen for the highest level of estimated exposure to perchloroethylene (OR = 11.38; 95% confidence interval: 1.04 to 124.85) and for exposure less than the median to kerosene/fuel/gasoil (OR = 8.53; 95% confidence interval: 1.11 to 65.62).CONCLUSIONS: These results do not provide conclusive evidence that exposure to solvents may increase risk of MF because they were not found in men.

Background It has been suggested that certain occupational exposures may play a role in breast cancer etiology. The recognition of high-risk occupations may give clues about potential mammary carcinogens in the work place. Methods We conducted a population-based case–control study in France including 1,230 breast cancer cases and 1,315 population controls with detailed information on lifetime work history. Odds ratios for women ever employed in an occupation or industry were adjusted for well-established risk factors for breast cancer. Results Adjusted odds ratios were marginally increased in some white-collar occupations, as well as in textile workers (2.4; 95% CI [0.9–6.0]), rubber and plastics product makers (1.8; 95% CI [0.9–3.5]), and in women employed for more than 10 years as nurses (1.4; 95% CI [0.9–2.1]) and as tailors/dressmakers (1.5; 95% CI [0.9–2.6]). The incidence of breast cancer was increased among women employed in the manufacture of chemicals, of non-metallic mineral products, and decreased among women in agriculture. Conclusions These findings suggest a possible role of occupational exposures in breast cancer, including night-shift work, solvents and endocrine disrupting chemicals and require further studies with detailed assessment of occupational exposures.

International audience; Lymphoid neoplasms (LNs), including non-Hodgkin's lymphoma (NHL), Hodgkin's lymphoma (HL), lymphoproliferative syndrome (LPS) and multiple myeloma (MM), are among the most frequent cancers ( approximately 17,000 new cases per year in France), after those related to smoking. LNs were investigated using the data from the ENGELA study. ENGELA is a multicenter hospital-based case-control study that was carried out in France over the period September 2000-December 2004. In all, 822 cases (397 NHL, 149 LH, 168 SLP and 108 MM) and 752 controls were included and described 5,481 and 5,188 first-degree relatives, respectively. A positive association with a familial history of hematopoietic cancer was observed for LN (OR = 1.7 [1.0-2.8]) overall and for LPS (OR = 3.2 [1.4-6.8]). The associations with HL (OR = 10.4 [2.0-53.8]) and NHL (OR = 2.4 [1.0-5.9]) were stronger for men. The associations were also stronger when the disease had been diagnosed before the relatives were aged 45 years. The results mainly support the involvement of genetic factors and suggest that at least some of those factors may be sex-linked. However, the slight overrepresentation of affected spouses among the cases might also support the responsibility of environmental factors.
