Knowledge About the Human Papillomavirus Vaccine Among Employees at a Tertiary Cancer Center: Room for Improvement

Introduction: The human papillomavirus (HPV) vaccine is recommended by the U.S. Centers for Disease Control and Prevention for routine vaccination of boys and girls to protect against HPV-related cancers and genital warts. To meet the Healthy People 2020 target for HPV vaccination, health care providers must understand the importance of strongly recommending the HPV vaccine to all eligible adolescents. We sought to determine HPV vaccination patterns among employees at a tertiary cancer center and their children and attitudes regarding HPV vaccination among the employees. Methods: All employees at a tertiary cancer center were invited to participate in a cross-sectional survey administered online during July and August 2015. The survey included questions about HPV vaccination of participants and their children, including reasons why vaccine-eligible employees and children had not been vaccinated. Results: Of those eligible, 13% of male and 33% of female employees and 44% of daughters and 24% of sons of employees had completed the vaccine series. The main reasons for not completing the series or not having one’s son completing the series were not knowing that the vaccine was needed and vaccine not recommended by a health care provider. The main reasons for not having one’s daughter complete the series were the two aforementioned reasons and daughter not yet sexually active. Conclusion: Opportunities exist to educate health care workers about the benefits of the HPV vaccine and to increase the number of providers who recommend HPV vaccination to their patients

A variant at a potentially functional microRNA-binding site in BRIP1 was associated with risk of squamous cell carcinoma of the head and neck

DNA double-strand breaks (DSBs) are one of the most serious forms of DNA damage to the cell, causing genomic instability and ultimately carcinogenesis. In this study, we hypothesized that single nucleotide polymorphisms (SNPs) at the micro RNA (miRNA)-binding sites of DSB repair genes may influence cancer risk by dysregulating target gene expression. To test our hypothesis, we firstly performed functional prediction for common SNPs in DSB genes and found 12 potentially functional SNPs located at the miRNA-binding sites. We then investigated their associations with risk of squamous cell carcinoma of the head and neck (SCCHN) in 1087 patients and 1090 cancer-free controls in a non-Hispanic white population. As a result, SNP rs7213430 in BRIP1 was found to be significantly associated with cancer risk (Ptrend = 0.021). Compared with the AA homozygotes, the G allele carriers had an increased risk of SCCHN (adjusted OR 1.16, 95 % CI 1.02–1.31). Marginal significance was found for another SNP rs15869 in BRCA2 (P = 0.053). Further, functional analyses showed that SNP rs7213430 is within the miR-101 seed-binding region, and the variant G allele could lead to significantly lower luciferase activity and BRIP1 mRNA expression, compared to the A allele with the presence of miR-101. Our results suggested that SNP rs7213430 in the 3′-UTR of BRIP1 might contribute to SCCHN susceptibility by affecting the binding activity of miR-101 and resulting in a decreased BRIP1 expression. Additional larger population and functional studies are warranted to confirm our findings

Clinical applications of B-type natriuretic peptide (BNP) testing

Many claims have been made in recent years regarding the utility of plasma B-type natriuretic peptide (BNP) concentration measurements in the diagnosis, risk stratification and monitoring of patients with heart failure. This paper summarizes the current evidence and provides guidance for practising clinicians. Overall, plasma BNP testing appears to be of most value in the diagnostic arena, where it is likely to improve the performance of non-specialist physicians in diagnosing heart failure. In clinical practice, BNP testing is best used as a ‘rule out' test for suspected cases of new heart failure in breathless patients presenting to either the outpatient or emergency care settings; it is not a replacement for echocardiography and full cardiological assessment, which will be required for patients with an elevated BNP concentration. Although work is ongoing in establishing the ‘normal' values of BNP, heart failure appears to be highly unlikely below a plasma concentration of 100pg/ml. However, as BNP levels rise with age and are affected by gender, comorbidity and drug therapy, the plasma BNP measurement should not be used in isolation from the clinical contex

A synthesis of evidence for cancer-specific screening interventions : A Preventive Medicine Golden Jubilee Review

The goal of cancer screening guidelines is to inform health practitioners to practice evidence-based cancer prevention. Cancer screening aims to detect treatable precancerous lesions or early-stage disease to enable actions aimed at decreasing morbidity and mortality. Continuous assessment of the available evidence for or against screening interventions by various organizations often results in conflicting recommendations and create challenges for providers and policymakers. Here we have summarized the current cancer screening recommendations by five leading organizations in North America and Europe: the National Cancer Institute's Physician Data Query (PDQ), the U.S. Preventive Services Task Force (USPSTF), the Canadian Task Force on Preventive Health Care (CTFPHC), the Cochrane Database of Systematic Reviews (CDSR), and the UK National Screening Committee for the National Health Service (UK NSC). All organizations assess evidence based on strength, quality, and quantity, and recommendations are similar although with differences with respect to screening start and stop ages. Recommendations are consistent for colorectal cancer screening with fecal occult blood test or fecal immunochemical test, cervical cancer screening with Pap-test, HPV-test, or co-testing, and breast cancer screening with mammography. However, guidelines vary with respect to age to start and end screening and testing frequency. Tests that have proven to be inefficient or whose use is capable of causing harm are routinely recommended against. Continuous review of screening guidelines is necessary to evaluate the many promising screening tests currently under investigation.publishedVersionPeer reviewe

Doping-induced carrier profiles in organic semiconductors determined from capacitive extraction-current transients

A method to determine the doping induced charge carrier profiles in lightly and moderately doped organic semiconductor thin films is presented. The theory of the method of Charge Extraction by a Linearly Increasing Voltage technique in the doping-induced capacitive regime (doping-CELIV) is extended to the case with non-uniform doping profiles and the analytical description is verified with drift-diffusion simulations. The method is demonstrated experimentally on evaporated organic small- molecule thin films with a controlled doping profile, and solution-processed thin films where the non- uniform doping profile is unintentional, probably induced during the deposition process, and a priori unknown. Furthermore, the method offers a possibility of directly probing charge-density distributions at interfaces between highly doped and lightly doped or undoped layers

Apoptotic capacity and risk of squamous cell carcinoma of the head and neck

Tobacco smoke and alcohol drinking are the major risk factors for squamous cell carcinoma of the head and neck (SCCHN). Smoking and drinking cause DNA damage leading to apoptosis, and insufficient apoptotic capacity may favor development of cancer because of the dysfunction of removing damaged cells. In the present study, we investigated the association between camptothecin (CPT)-induced apoptotic capacity and risk of SCCHN in a North American population
