Zika Virus Infection during Pregnancy and Effects on Early Childhood Development, French Polynesia, 2013-2016.

Congenital Zika virus syndrome consists of a large spectrum of neurologic abnormalities seen in infants infected with Zika virus in utero. However, little is known about the effects of Zika virus intrauterine infection on the neurocognitive development of children born without birth defects. Using a case-control study design, we investigated the temporal association of a cluster of congenital defects with Zika virus infection. In a nested study, we also assessed the early childhood development of children recruited in the initial study as controls who were born without known birth defects,. We found evidence for an association of congenital defects with both maternal Zika virus seropositivity (time of infection unknown) and symptomatic Zika virus infection during pregnancy. Although the early childhood development assessment found no excess burden of developmental delay associated with maternal Zika virus infection, larger, longer-term studies are needed.

Prevention of sexually transmitted infections among girls and young women in relation to their HPV vaccination status.

BACKGROUND: Having been vaccinated against the human papilloma virus (HPV) may affect other behaviours related to sexual health. This study assessed knowledge and behaviour relevant to the prevention of sexually transmitted infections (STIs) among girls/women aged 14-23 years in relation to their HPV vaccination status. METHODS: From November 2008 to February 2009, 328 girls/women from the Rhône-Alpes region were recruited by general practitioners and completed a self-administered questionnaire. RESULTS: In all, 316 of the 328 respondents provided information on their HPV vaccination status: 135 (42.7%) had been vaccinated (51.2% of girls aged 14-16 years, 44% of women aged 17-20 years and 18.9% of 21-23-year-olds). Knowledge about HPV and the Pap smear was poor overall but greater in those who had been vaccinated: vaccinated 14-16-year-olds were significantly more likely to know the aim of the Pap smear than those not vaccinated (72.7% vs. 41.3%, P < 0.001), and vaccinated 21-23-year-olds were more likely to know about the need to continue Pap smear screening, despite vaccination (60.0% vs. 25.6%, P = 0.06). Irrespective of vaccination status, >80% cited condoms as a means of STI prevention and >85% of those who were sexually active used them. No difference was observed between vaccinated and non-vaccinated groups regarding requests for HIV serology, history of abortions or emergency hormonal contraception. CONCLUSION: Knowledge about cervical cancer prevention was better among those who had been vaccinated against HPV than among those who had not. Knowledge and behaviour relevant to STI prevention seemed appropriate whatever the respondents' vaccination status.

French women's knowledge of and attitudes towards cervical cancer prevention and the acceptability of HPV vaccination among those with 14 - 18 year old daughters: a quantitative-qualitative study.

BACKGROUND: In France, it is recommended that girls and women aged 14-23 are vaccinated against the human papillomavirus (HPV). However, French women's knowledge of and attitude towards the vaccine has been little studied. METHODS: Thirty-nine general practitioners, representative of those working in the large Rhône-Alpes region, offered a self-administered questionnaire on cervical cancer (CC) prevention to all 18-65 year-old women who came for consultation during June and July 2008. In addition, semi-structured interviews were undertaken with a sample of those who had daughters aged 14-18. RESULTS: Of the 1,478 women who completed the questionnaire, only 16.9% mentioned HPV as the cause of CC, even though 76.2% knew of the vaccine. 210 women had daughters aged 14-18, and 32 were interviewed. Compared with the wider group, more of these women were aware of the HPV vaccine (91.4%). 44.8% knew the target population and 17.1% the recommended ages for vaccination. 54.3% favoured HPV vaccination; 37.2% were undecided and only 0.9% were opposed. The main barrier to acceptance was the recency of the vaccine's introduction and concern about possible side effects (54.9%); 14.1% preferred to rely on their GP's decision. Factors associated with acceptance of the HPV vaccine were having previously vaccinated a child against pneumococcus (OR=3.28 [1.32-8.11]) and knowing the target population for HPV vaccination (OR=2.12 [1.15-3.90]). Knowing the recommended frequency of Papanicolaou smear testing (Pap test) screening was associated with lower acceptance (OR=0.32 [0.13-0.82]). CONCLUSIONS: Few mothers are opposed to HPV vaccination. Factors associated with acceptability were knowledge about the vaccine, acceptance of other vaccines and, unexpectedly, lack of knowledge about the recommended frequency of Pap testing. On multivariate analysis, compliance with recommendations for Pap test screening and socioeconomic factors had no effect on views about HPV vaccination. Given that concern about possible side effects is the major barrier to wider acceptance of the HPV vaccine in France, GPs have a key role in providing information.

Disparities of perceptions and practices related to cervical cancer prevention and the acceptability of HPV vaccination according to educational level in a French cross-sectional survey of 18-65 years old women.

INTRODUCTION: We aimed to study the relationships between educational level, women's knowledge about cervical cancer (CC), and acceptance of HPV vaccination for their daughters. METHODS: We analysed data from a quantitative (self-administrated questionnaire) and qualitative (semi-structured interviews) cross-sectional study performed in 2008 among 1,229 French 18-65-year-old women recruited by general practitioners. Women were categorized into three educational level groups: low (LEL: 43.9%), medium (MEL: 33.4%) and high (HEL: 22.6%). RESULTS: Knowledge about CC and its prevention was lower among LEL women. In the 180 mothers of 14-18-year-old daughters (99 LEL, 54 MEL, 45 HEL), acceptance of HPV vaccine was higher in LEL (60.4%) and MEL (68.6%) than in HEL mothers (46.8%). Among LEL mothers, those who were favourable to HPV vaccination were more likely to be young (OR = 8.44 [2.10-34.00]), to be vaccinated against hepatitis B (OR = 4.59 [1.14-18.52]), to have vaccinated their children against pneumococcus (OR = 3.52 [0.99-12.48]) and to present a history of abnormal Pap smear (OR = 6.71 [0.70-64.01]). CONCLUSION: Although LEL women had poorer knowledge about CC and its prevention, they were more likely to accept HPV vaccination than HEL mothers.

Practices and opinions regarding HPV vaccination among French general practitioners: evaluation through two cross-sectional studies in 2007 and 2010.

OBJECTIVES: To use both quantitative and qualitative methods to investigate the evolution of practices and opinions regarding human papillomavirus (HPV) vaccination among French general practitioners. METHODS: A cross-sectional study (self-questionnaires) was performed in 2007 and repeated in 2010 among 271 general practitioners. Semi-structured interviews were conducted on 27 voluntary participants by a sociologist and analyzed according to content analysis. RESULTS: Acceptability of HPV vaccination had increased from 2007 to 2010 (79.9 vs. 87.1%, respectively), just as the practice of HPV vaccination among 14-year-old girls (19.0 vs. 49.1%, respectively). Though about 60% reported complications associated with HPV vaccination, irrespective of year, the types of difficulties have varied: difficulties related to "questions asked by patients" had decreased, though concerns about side effects had remained stable. During interviews, difficulties related to "the reason for medical consultation" and "the target age" were often associated with addressing the issue of sexuality, especially when the parents were present. CONCLUSIONS: Although the high level of acceptability of HPV vaccination among general practitioners, which increased from 2007 to 2010, there remain difficulties in addressing this practice.

Professional exposure to goats increases the risk of pneumonic-type lung adenocarcinoma: results of the IFCT-0504-Epidemio study.

Pneumonic-type lung adenocarcinoma (P-ADC) represents a distinct subset of lung cancer with specific clinical, radiological, and pathological features. Given the weak association with tobacco-smoking and the striking similarities with jaagsiekte sheep retrovirus (JSRV)-induced ovine pulmonary adenocarcinoma, it has been suggested that a zoonotic viral agent infecting pulmonary cells may predispose to P-ADC in humans. Our objective was to explore whether exposure to domestic small ruminants may represent a risk factor for P-ADC. We performed a multicenter case-control study recruiting patients with P-ADC as cases and patients with non-P-ADC non-small cell lung cancer as controls. A dedicated 356-item questionnaire was built to evaluate exposure to livestock. A total of 44 cases and 132 controls were included. At multivariate analysis, P-ADC was significantly more associated with female gender (Odds-ratio (OR) = 3.23, 95% confidence interval (CI): 1.32-7.87, p = 0.010), never-smoker status (OR = 3.57, 95% CI: 1.27-10.00, p = 0.015), personal history of extra-thoracic cancer before P-ADC diagnosis (OR = 3.43, 95% CI: 1.10-10.72, p = 0.034), and professional exposure to goats (OR = 5.09, 95% CI: 1.05-24.69, p = 0.043), as compared to other subtypes of lung cancer. This case-control suggests a link between professional exposure to goats and P-ADC, and prompts for further epidemiological evaluation of potential environmental risk factors for P-ADC.
