  • Vulnerable population

    Imagine you are a policymaker for your city or town. Based on what you know, and what you have learned in this course, what would you modify or improve to make a positive change in the life of a vulnerable group we have not covered in class? Would you consult the vulnerable group when developing programs or policies? Why or why not? Which policy would you create to improve health care services accessibility, cost, and quality related to your selected group?

    Your initial contribution should be 250 to 300 words in length. Your research and claims must be supported by a minimum of two scholarly sources beyond your course text. Use proper APA formatting for in-text citations and references as outlined in the Ashford Writing Center.

  • Mosquitoes reproduction

    Discussion

    To prepare for this Discussion: Walk around a two-block radius near where you live or work. Look to see if you can spot any areas where mosquitoes may reproduce. These sites may include abandoned tires, rainwater collection systems that have been installed at homes, parks or golf courses, low sections at roadsides or near sidewalks, and the like. You may include pictures of sites that you find to enhance your discussion thread. Note any positive or negative findings that you observe. Have steps been taken to prevent mosquito breeding? Find out what your community health department does for mosquito abatement. Discover who in your community you would contact to report deficiencies/negative findings. Determine what you can do, as a PHN, to change policy to reduce mosquito breeding grounds in your neighborhood. By Day 3 Post your findings regarding mosquito breeding grounds in a two-block radius near where you live or work. Include any preventative strategies you can see that are already in place. Report on the role your local health department plays in mosquito abatement and to whom you would report negative findings. Then, describe your role as a BSN in changing policy to ensure a healthier climate (reduced mosquito breeding grounds) in your neighborhood.

    10. You are conducting a prospective study of hepatitis B virus (HBV) infection and its relation to liver failure. Normally, the immune system neutralizes the virus and most infected people are left with HBV antibodies but no detectable circulating virus. A small proportion of people who are infected with HBV remain with circulating virus itself (HBV viremic) and it is this group that is believed to be at high risk of liver failure. You put together a cohort study of 500 persons who are HBV viremic and 500 persons with HBV antibodies but who do not have detectable virus. You follow this cohort for five years. Among the first group that are HBV viremic, 50 persons develop liver failure: 5 at 10 months, 10 at 20 months, 20 at 36 months, 10 at 42 months, and 5 at 50 months. Among the second group that are HBV antibody positive but who do not have detectable virus (i.e., HBV non-viremic), 10 persons develop liver failure: 5 at 32 months and 5 at 55 months.

    a. Calculate the person-time of follow up for each group. Show calculations. (6 pts)

    b. Calculate the liver failure incidence rate for each group (i.e., HBV viremic and HBV non-viremic). Express each rate with an appropriate metric in the denominators. Show calculations. (6 pts)

    c. How much of an increase of liver failure incidence is seen among persons with detectable HBV virus compared with those who have HBV antibodies but no detectable virus? Give results for absolute and relative differences of incidence. Show calculations. (6 pts)

    17. In 2002, investigators started a study of the association of cholesterol levels and stroke in a group of 2,000 healthy persons who had participated in a cholesterol screening program in 1992. The investigators determined exposure categories using cholesterol levels in all persons that were measured at the time of the screening program. A cut-off value of 200 mg/dL was used to define ‘high’ cholesterol while those with levels below 200 were identified as having ‘low’ cholesterol. Using this definition, 1,000 persons had ‘high’ cholesterol levels while the remaining 1,000 persons had ‘low’ cholesterol. The investigators then ascertained whether these originally healthy persons had experienced a stroke. They determined that 150 cases of stroke occurred by the end of 2002, with 113 cases occurring in the high cholesterol group.

    a. What is the study design that the investigators used? (2 pts) A. Case-control study B. Retrospective cohort study C. Prospective cohort study D. Cross-sectional study E. Randomized clinical trial

    18. The two major purposes of random assignment in a clinical trial are to (select two): (4 pts) A. ensure that study subjects are representative of the general population B. facilitate double-blinding C. ensure that the study groups are comparable on baseline characteristics D. facilitate measurement of outcome variables E. reduce selection bias in allocation of treatment
