Abstract Title: 

Air Pollution, Clustering of Particulate Matter Components, and Breast Cancer in the Sister Study: A U.S.-Wide Cohort.

Abstract: 

BACKGROUND: Particulate matter (PM) is a complex mixture. Geographic variations in PM may explain the lack of consistent associations with breast cancer.OBJECTIVE: We aimed to evaluate the relationship between air pollution, PM components, and breast cancer risk in a United States-wide prospective cohort.METHODS: We estimated annual average ambient residential levels of particulate matterandin aerodynamic diameter (and, respectively) and nitrogen dioxide () using land-use regression for 47,433 Sister Study participants (breast cancer-free women with a sister with breast cancer) living in the contiguous United States. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for risk associated with an interquartile range (IQR) increase in pollutants. Predictive-means were used to assign participants to clusters derived fromcomponent profiles to evaluate the impact of heterogeneity in themixture. For, we investigated effect measure modification by component cluster membership and by geographic region without regard to air pollution mixture.RESULTS: During follow-up (), 2,225 invasive and 623 ductal carcinoma(DCIS) cases were identified.andwere associated with breast cancer overall [(95% CI:0.99, 1.11) and 1.06 (95% CI:1.02, 1.11), respectively] and with DCIS but not with invasive cancer. Invasive breast cancer was associated withonly in the Western United States [(95% CI:1.02, 1.27)] andonly in the Southern United States [(95% CI:1.01, 1.33)].was associated with a higher risk of invasive breast cancer among two of seven identified composition-based clusters. A higher risk was observed [(95% CI: 0.97, 1.60)] in a California-based cluster characterized by low S and high Na and nitrate () fractions and for another Western United States cluster [(95% CI: 0.90, 2.85)], characterized by high fractions of Si, Ca, K, and Al.CONCLUSION: Air pollution measures were related to both invasive breast cancer and DCIS within certain geographic regions and PM component clusters. https://ift.tt/37xLO8r.

Abstract Title: 

The introduction of the meningococcal B (MenB) vaccine (Bexsero®) into the national infant immunisation programme–New challenges for public health.

Abstract: 

The United Kingdom is the first country to introduce Bexsero(®) (GSK Biologicals), a multicomponent, protein-based vaccine against meningococcal group B (MenB), into the national infant immunisation programme. This vaccine is like no other licensed vaccine and poses a number of implementation and surveillance challenges in England. From 01 September 2015, UKinfants were offered a reduced two dose primary immunisation schedule at 2 and 4 months followed by a booster at 12 months. Because of high rates of fever post-vaccination, parents were advised to give their infants three doses of prophylactic paracetamol, with the first dose given as soon as possible after the primary MenB vaccination dose. Since the vaccine only protects against 73-88% of MenB strains causing invasive disease in England, clinical isolates and PCR-positive samples will require extensive characterisation by the Meningococcal Reference Unit (MRU) at Public Health England (PHE)in order to monitor vaccine effectiveness and identify potential vaccine failures. PHE is also conducting detailed clinical and epidemiological surveillance to assess the impact of the MenB immunisation programme on the morbidity and mortality associated with invasive meningococcal disease in infants and young children.

Abstract Title: 

Effect of age on the incidence of aseptic meningitis following immunization with monovalent mumps vaccine.

Abstract: 

OBJECTIVE: The purpose of this study was to determine the risk of aseptic meningitis after mumps vaccination in younger children compared with older children.METHODS: This prospective cohort study included a total of 21,465 children under 18 years of age who had received the first dose of three of the Japanese mumps monovalent vaccine. We compared the cumulative incidence of aseptic meningitis for 30 days after vaccination among the following age groups:≤ 1, 2, 3-4, and ≥ 5 years old. We also investigated the cumulative incidence of salivary gland swelling, a fever (≥ 38°C) lasting at least 3 days during the 10 to 25 days following immunization, vomiting of 3 times or more, headache, and seizure.RESULTS: A total of 10 aseptic meningitis, 551 salivary gland swelling, 844 fevers, 669 vomiting, 757 headaches, and 29 seizure cases were identified. The cumulative incidence of aseptic meningitis increased with age (0.016%, 0.021%, 0.066%, and 0.096%, respectively). Statistical significance was observed between children≥ 3 years old and those

Abstract Title: 

Vaccines for prevention of group B meningococcal disease: Not your father's vaccines.

Abstract: 

For decades, there was no licensed vaccine for prevention of endemic capsular group B meningococcal disease, despite the availability of vaccines for prevention of the other most common meningococcal capsular groups. Recently, however, two new vaccines have been licensed for prevention of group B disease. Although immunogenic and considered to have an acceptable safety profile, there are many scientific unknowns about these vaccines, including effectiveness against antigenically diverse endemic meningococcal strains; duration of protection; whether they provide any herd protection; and whether there will be meningococcal antigenic changes that will diminish effectiveness over time. In addition, these vaccines present societal dilemmas that could influence how they are used in the U.S., including high vaccine cost in the face of a historically low incidence of meningococcal disease. These issues are discussed in this review.

Abstract Title: 

Meningococcal carriage among a university student population – United States, 2015.

Abstract: 

OBJECTIVES: Several outbreaks of serogroup B meningococcal disease have occurred among university students in recent years. In the setting of high coverage of the quadrivalent meningococcal conjugate vaccine and prior to widespread use of serogroup B meningococcal vaccines among adolescents, we conducted surveys to characterize the prevalence and molecular characteristics of meningococcal carriage among university students.METHODS: Two cross-sectional oropharyngeal carriage surveys were conducted among undergraduates at a Rhode Island university. Isolates were characterized using slide agglutination, real-time polymerase chain reaction (rt-PCR), and whole genome sequencing. Adjusted prevalence ratios and 95% confidence intervals were calculated using Poisson regression to determine risk factors for carriage.RESULTS: A total of 1837 oropharyngeal specimens were obtained from 1478 unique participants. Overall carriage prevalence was 12.7-14.6% during the two survey rounds, with 1.8-2.6% for capsular genotype B, 0.9-1.0% for capsular genotypes C, W, or Y, and 9.9-10.8% for nongroupable strains by rt-PCR. Meningococcal carriage was associated with being male, smoking, party or club attendance, recent antibiotic use (inverse correlation), and recent respiratory infections.CONCLUSIONS: In this university setting, the majority of meningococcal carriage was due to nongroupable strains, followed by serogroup B. Further evaluation is needed to understand the dynamics of serogroup B carriage and disease among university students.

Abstract Title: 

Effect of inactivated poliovirus vaccine on the antibody response to Bordetella pertussis antigens when combined with diphtheria-pertussis-tetanus vaccine.

Abstract: 

To determine if inactivated poliovirus vaccine combined with diphtheria and tetanus toxoids and whole-cell pertussis vaccine interferes with the immunogenicity of pertussis vaccine, we performed a randomized trial of diphtheria and tetanus toxoids and pertussis vaccine combined with inactivated poliovirus vaccine given as a single injection or as two separate injections at the same visit to infants immunized at 2, 4, and 6 months of age. A total of 84 infants were enrolled in the study; 44 received the single injection, and 40 received separate injections. Before immunization, there were no differences in antibody values between the two groups. After two vaccine doses, infants immunized with the single injection had significantly lower values of antibody to filamentous hemagglutinin (8.3 vs. 23.7 ELISA units; P

Abstract Title: 

Serological evidence of SV40 infections in HIV-infected and HIV-negative adults.

Abstract: 

SV40 is a simian polyomavirus that was a contaminant of some viral vaccines administered to people between 1955 and 1962. SV40 DNA has recently been found associated with several types of human tumors, suggesting that the virus is present in humans. We examined sera from patients infected with human immunodeficiency virus type 1 (HIV-1) as well as from HIV-1-negative controls to determine the prevalence of SV40 neutralizing antibodies using a specific plaque reduction assay. We found that 16.1% of HIV-infected patients (n = 236) were seropositive for SV40, as compared to 12.0% of HIV-negative control volunteers (n = 108) and 11.1% of HIV-negative patients (n = 72). These differences were not statistically significant. As individuals born between 1941 and 1962 had the highest chance of having received SV40-contaminated poliovaccines, we analyzed SV40 seropositivity rates based on year of birth. SV40 antibody rates for HIV-infected patients born before 1941, between 1941 and 1962, and after 1962 were 17.1%, 16.3%, and 11.8%, respectively. For the HIV-negative subjects, the rates were 12.5%, 12.0%, and 9.7%, respectively. There was no correlation between SV40 seropositivity and either the stage of disease in HIV-infected patients or the race/ethnicity. Also, there was no correlation between the presence of SV40 neutralizing antibody and the titer of neutralizing antibody to human polyomavirus BKV. The SV40 seropositivity rates in the patients born between 1941 and 1962 may be explained by the likelihood of those individuals having received SV40-contaminated vaccines, but the detection of SV40 neutralizing antibody in individuals born after 1962 (with no risk of having received contaminated vaccines) is significant. Although cross-reactive antibodies might theoretically contribute to the observed reactivities, these results suggest that SV40 neutralizing antibodies are present in certain individuals and raise the possibility that SV40 continues to infect humans long after vaccines were freed from contamination.

Abstract Title: 

Risk of febrile seizures and epilepsy after vaccination with diphtheria, tetanus, acellular pertussis, inactivated poliovirus, and Haemophilus influenzae type B.

Abstract: 

CONTEXT: Vaccination with whole-cell pertussis vaccine carries an increased risk of febrile seizures, but whether this risk applies to the acellular pertussis vaccine is not known. In Denmark, acellular pertussis vaccine has been included in the combined diphtheria-tetanus toxoids-acellular pertussis-inactivated poliovirus-Haemophilus influenzae type b (DTaP-IPV-Hib) vaccine since September 2002.OBJECTIVE: To estimate the risk of febrile seizures and epilepsy after DTaP-IPV-Hib vaccination given at 3, 5, and 12 months.DESIGN, SETTING, AND PARTICIPANTS: A population-based cohort study of 378,834 children who were born in Denmark between January 1, 2003, and December 31, 2008, and followed up through December 31, 2009; and a self-controlled case series (SCCS) study based on children with febrile seizures during follow-up of the cohort.MAIN OUTCOME MEASURES: Hazard ratio (HR) of febrile seizures within 0 to 7 days (0, 1-3, and 4-7 days) after each vaccination and HR of epilepsy after first vaccination in the cohort study. Relative incidence of febrile seizures within 0 to 7 days (0, 1-3, and 4-7 days) after each vaccination in the SCCS study.RESULTS: A total of 7811 children were diagnosed with febrile seizures before 18 months, of whom 17 were diagnosed within 0 to 7 days after the first (incidence rate, 0.8 per 100,000 person-days), 32 children after the second (1.3 per 100,000 person-days), and 201 children after the third (8.5 per 100,000 person-days) vaccinations. Overall, children did not have higher risks of febrile seizures during the 0 to 7 days after the 3 vaccinations vs a reference cohort of children who were not within 0 to 7 days of vaccination. However, a higher risk of febrile seizures was found on the day of the first (HR, 6.02; 95% CI, 2.86-12.65) and on the day of the second (HR, 3.94; 95% CI, 2.18-7.10), but not on the day of the third vaccination (HR, 1.07; 95% CI, 0.73-1.57) vs the reference cohort. On the day of vaccination, 9 children were diagnosed with febrile seizures after the first (5.5 per 100,000 person-days), 12 children after the second (5.7 per 100,000 person-days), and 27 children after the third (13.1 per 100,000 person-days) vaccinations. The relative incidences from the SCCS study design were similar to the cohort study design. Within 7 years of follow-up, 131 unvaccinated children and 2117 vaccinated children were diagnosed with epilepsy, 813 diagnosed between 3 and 15 months (2.4 per 1000 person-years) and 1304 diagnosed later in life (1.3 per 1000 person-years). After vaccination, children had a lower risk of epilepsy between 3 and 15 months (HR, 0.63; 95% CI, 0.50-0.79) and a similar risk for epilepsy later in life (HR, 1.01; 95% CI, 0.66-1.56) vs unvaccinated children.CONCLUSIONS: DTaP-IPV-Hib vaccination was associated with an increased risk of febrile seizures on the day of the first 2 vaccinations given at 3 and 5 months, although the absolute risk was small. Vaccination with DTaP-IPV-Hib was not associated with an increased risk of epilepsy.

Abstract Title: 

Systematic review of mucosal immunity induced by oral and inactivated poliovirus vaccines against virus shedding following oral poliovirus challenge.

Abstract: 

Inactivated poliovirus vaccine (IPV) may be used in mass vaccination campaigns during the final stages of polio eradication. It is also likely to be adopted by many countries following the coordinated global cessation of vaccination with oral poliovirus vaccine (OPV) after eradication. The success of IPV in the control of poliomyelitis outbreaks will depend on the degree of nasopharyngeal and intestinal mucosal immunity induced against poliovirus infection. We performed a systematic review of studies published through May 2011 that recorded the prevalence of poliovirus shedding in stool samples or nasopharyngeal secretions collected 5-30 days after a"challenge"dose of OPV. Studies were combined in a meta-analysis of the odds of shedding among children vaccinated according to IPV, OPV, and combination schedules. We identified 31 studies of shedding in stool and four in nasopharyngeal samples that met the inclusion criteria. Individuals vaccinated with OPV were protected against infection and shedding of poliovirus in stool samples collected after challenge compared with unvaccinated individuals (summary odds ratio [OR] for shedding 0.13 (95% confidence interval [CI] 0.08-0.24)). In contrast, IPV provided no protection against shedding compared with unvaccinated individuals (summary OR 0.81 [95% CI 0.59-1.11]) or when given in addition to OPV, compared with individuals given OPV alone (summary OR 1.14 [95% CI 0.82-1.58]). There were insufficient studies of nasopharyngeal shedding to draw a conclusion. IPV does not induce sufficient intestinal mucosal immunity to reduce the prevalence of fecal poliovirus shedding after challenge, although there was some evidence that it can reduce the quantity of virus shed. The impact of IPV on poliovirus transmission in countries where fecal-oral spread is common is unknown but is likely to be limited compared with OPV.
