To analyze:
Michelle Khan and her co-workers published their findings on a 10-year study in cervical cancer incidence and human papilloma virus status in 20,514 women in 2003. They gave a graph for their results. The group that has women infected with both HPV16 and HPV18 is to be analyzed.
Given:
The graphical representation of the study conducted by Michelle and her co-workers:
The key for the graph is given below.
Introduction:
Cervical cancer is a cancer of cervical cells in the uterus. It is mostly caused by the Human Papilloma Virus, which is sexually transmitted. Sexually active women are at a greater risk of getting infected by this virus. All the strains of HPV do not cause cervical cancer. Two strains of HPV—HPV16 and HPV18—cause cervical cancer, out of the 100 known strains.

- In a Cervical Cancer screening program, 500 asymptomatic women were examined using the Pap smear test. 200 of the women who truly had lesions were correctly classified; 14 with lesions were wrongly classified as negative. 253 women who had no lesions were correctly classified; 33 women with no lesions were wrongly reported as positive. (A) Summarise the information provided in an appropirate table. (B) Based on the information above, calculate the Sensitivity, Specificity, Positive and Negative Predictive Values of the Pap smear test.arrow_forwardThe vaccine Gardasil that targets human papilloma virus (HPV), the etiological agent of genital warts, was developed after the anti-HPV medication podofilox. Why would doctors still want a vaccine created after anti-viral medications were available?arrow_forward1) What factor(s) most likely account for the increase in the diagnosis of autism spectrum disorders (ASDs) over the past two decades? 2) What does the research say about the purported link between vaccines and ASDs? 3) Would you or would you not choose to have your child receive routine childhood vaccinations?arrow_forward
- A community health clinic in western Illinois has seen an increase in patients with human papillomavirus (HPV). HPV/Pap cotesting has been recommended by the clinic's CMO. HPV/Pap cotest involves a HPV test, where a sample of cells is taken from the cervix, and a Pap test, which checks for cervical cancer cells, are completed at the same time. She suggests that this level of screening test is more accurate than either method alone. Below is information on the test's validity provided by the developers of the screening test. HPV No HPV ТОТALS Positive Test Result Negative Test Result TOTALS 192 37 229 152 189 171 400 19 211 1. Using the 2-by-2 contingency table above, calculate and interpret the following: Sensitivity • Specificity Positive predicetive value Negative predictive value Likelihood ratio for a positive test Likelihood ratio for a negative testarrow_forwardChoose all the true statements regarding coronavirus proteins. Vaccine preventable diseases include COVID-19. For coronaviruses, it is more likely to find evolving mutations in the portion of the spike protein than the nucleocapsid protein. Mutations in the genetic code for the spike protein will produce 3D changes that are more likely to affect vaccine efficacy than changes to the nucleocapsid protein code. The nucleocapsid protein interacts with viral nucleic acid specifically whereas the spike protein interacts with the host protein non-specifically.arrow_forwardWhat are the main biomarkers in the blood that can be used to diagnose HIV infection?

- What is the Coronavirus? Is it a living organism? How does it reproduce? The current vaccines that are being distributed in the United States are made by Pfizer, Moderna, and Johnson and Johnson.
