Preventive services required for performance measurement often are completed in outside health systems and not captured in electronic medical records (EMRs). A before-after study was conducted to examine the ability of clinical decision support (CDS) to improve performance on preventive quality measures, capture clinician-reported services completed elsewhere, and patient/medical exceptions and to describe their impact on quality measurement. CDS improved performance on colorectal cancer screening, osteoporosis screening, and pneumococcal vaccination measures ( P < ...

BACKGROUND: The high burden of cervical cancer in Zambia prompted the Ministry of Health and partners to develop the cervical cancer prevention program in Zambia (CCPPZ) in 2006. Despite this intervention more women continue to die from the disease and there is little understanding of factors that may be linked with abnormal cervical lesions in the general population. We therefore examined if educational attainment is associated with abnormal cervical lesions among Zambian women aged 15 to 49 years...

Epigenetic dysregulation is important in cervical cancer development, but the underlying mechanism is largely unknown. Increasing evidence indicates that DNA methylation is sensitive to changes in microenvironmental factors, such as nitric oxide (NO) in the chronic inflammatory cervix. However, the epigenomic effects of NO in cancer have not been investigated. In this study, we explored the methylomic effects of nitroxidative stress in HPV-immortalized precancerous cells. Chronic NO exposure promoted the acquisition of malignant phenotypes such as cell growth, migration, invasion, and anchorage-independent growth...

Women vaccinated against HPV16/18 are approaching the age for cervical screening, however an updated screening algorithm has not been agreed. We use a microsimulation model calibrated to real published data to determine the appropriate screening intensity for vaccinated women. Natural histories in the absence of vaccination were simulated for 300,000 women using 10,000 sets of transition probabilities. Vaccination with i) 100% efficacy against HPV16/18, ii) 15% cross-protection, iii) waning vaccine efficacy, and iv) 100% efficacy against HPV16/18/31/33/45/52/58 was added, as were a range of screening scenarios appropriate to the UK...

REVIEW
Samuel Alizon, Carmen Lía Murall, Ignacio G Bravo
Most infections by human papillomaviruses (HPVs) are `acute', that is non-persistent. Yet, for HPVs, as for many other oncoviruses, there is a striking gap between our detailed understanding of chronic infections and our limited data on the early stages of infection. Here we argue that studying HPV acute infections is necessary and timely. Focusing on early interactions will help explain why certain infections are cleared while others become chronic or latent. From a molecular perspective, descriptions of immune effectors and pro-inflammatory pathways during the initial stages of infections have the potential to lead to novel treatments or to improved handling algorithms...

Cervical carcinoma is a frequent malignancy in developing countries despite being a preventable disease. For the first time, four screening tests were used simultaneously for identifying women with a risk of developing cervical cancer, to help clinicians and policy makers to implement the best strategy for reducing the burden of this disease. Women visiting a hospital in India were enrolled after institutional ethics clearance and informed consent. Visual inspection using acetic acid and Pap smear tests were performed on 2683 women, and 104 had abnormal cytology: atypical squamous cells of undetermined significance (n = 29), low-grade squamous intraepithelial lesion (n = 41), high-grade squamous intraepithelial lesion (n = 17), and squamous cell carcinoma (n = 17)...
