RESUMO

BACKGROUND: Although several cross-sectional studies have shown that aircraft noise exposure was associated with an increased risk of hypertension, a limited number of longitudinal studies have addressed this issue. This study is part of the DEBATS (Discussion on the health effect of aircraft noise) research programme and aimed to investigate the association between aircraft noise exposure and the incidence of hypertension. METHODS: In 2013, 1244 adults living near three major French airports were included in this longitudinal study. Systolic and diastolic blood pressure, as well as demographic and lifestyle factors, were collected at baseline and after 2 and 4 years of follow-up during face-to-face interviews. Exposure to aircraft noise was estimated for each participant's home address using noise maps. Statistical analyses were performed using mixed Poisson and linear regression models adjusted for potential confounding factors. RESULTS: A 10 dB(A) increase in aircraft noise levels in terms of Lden was associated with a higher incidence of hypertension (incidence rate ratio (IRR)=1.36, 95% CI 1.02 to 1.82). The association was also significant for Lday (IRR 1.41, 95% CI 1.07; to 1.85) and Lnight (IRR 1.31, 95% CI 1.01 to 1.71). Systolic and diastolic blood pressure increased with all noise indicators. CONCLUSION: These results strengthen those obtained from the cross-sectional analysis of the data collected at the time of inclusion in DEBATS, as well as those from previous studies conducted in other countries. Hence, they support the hypothesis that aircraft noise exposure may be considered as a risk factor for hypertension.

RESUMO

OBJECTIVE: To assess the prevalence of all known human herpesviruses (HHV) in tonsils of an age-stratified large sample of immunocompetent children and adults. METHODS: Patients undergoing tonsillectomy for benign indications were recruited in 19 French hospitals. After resection, the entire outer surfaces of right and left half tonsils were extensively brushed. A highly sensitive species-specific multiplex assay was used to detect herpes simplex virus 1 (HSV1), HSV2, Epstein-Barr virus (EBV; types 1 and 2), and human cytomegalovirus (CMV) DNA in 688, as well as varicella zoster virus (VZV), HHV6A, HHV6B, HHV7, and Kaposi's sarcoma-associated herpesvirus (KSHV) DNA in a subset of 440 tonsil brushings. RESULTS: Overall 85% of tonsil brushing samples were infected with at least one HHV species. HHV7 and EBV were the most prevalent (≈70%), followed by HHV6B (≈50%), HSV1, CMV, VZV (≈2%), and KSHV and HSV2 (<1%), while HHV6A was not detected. EBV prevalence was significantly higher in adults than in children, whereas it was opposite for HHV6B and VZV. No difference in HHV prevalence was observed by sex. In multivariate analysis, EBV detection was associated with age greater than or equal to 15 years (prevalence ratio [PR] = 1.8; 95% confidence interval [CI]: 1.5-2.3) and marginally with tobacco smoking (PR = 1.2; 95% CI: 1.1-1.3). CONCLUSION: Differing patterns of HHV infection in tonsils in a large age-stratified population were described. This study is by far the largest available and shows that EBV, HHV6B, and HHV7 are commonly detected in the tonsils in both men and women, in contrast to other HHVs.

RESUMO

The prevalence of 13 polyomaviruses (PyVs) in the tonsil brushings and gargles of immunocompetent children and adults was assessed. Patients undergoing tonsillectomy for benign indications were recruited in 19 centres in France. After resection, the entire outer surface of the right and left halves of the tonsils was brushed extensively. Gargles were also collected prior to surgery in selected adults. A species-specific multiplex assay was used to detect the DNA of 13 PyVs. In tonsil brushings (n=689), human PyV 6 (HPyV6) and Merkel cell PyV (MCPyV) were the most prevalent (≈15 %), followed by trichodysplasia spinulosa-associated PyV (TSPyV), BKPyV, Washington University PyV (WUPyV) and human PyV 9 (HPyV9) (1 to 5 %), and human PyV 7 (HPyV7), John Cunningham PyV (JCPyV) and Simian virus 40 (SV40) (<1 %), while no Karolinska Institute PyV (KIPyV), Malawi PyV (MWPyV), human PyV 12 (HPyV12) or Lyon IARC PyV (LIPyV) were detected. The prevalence of TSPyV and BKPyV was significantly higher in children versus adults, whereas for HPyV6 the opposite was found. HPyV6 and WUPyV were significantly more prevalent in men versus women. In gargles (n=139), MCPyV was the most prevalent (≈40 %), followed by HPyV6, HPyV9 and LIPyV (2 to 4 %), and then BKPyV (≈1 %), while other PyVs were not detected. MCPyV and LIPyV were significantly more prevalent in gargles compared to tonsil brushings, in contrast to HPyV6. We described differing patterns of individual PyV infections in tonsils and gargles in a large age-stratified population. Comparison of the spectrum of PyVs in paired tonsil samples and gargles adds to the current knowledge on PyV epidemiology, contributing towards a better understanding of PyV acquisition and transmission and its potential role in head and neck diseases.
