What do you think about the longitudinal NIH-funded Bogalusa Heart Study, created by cardiologist Gerald Bevenson in 1972? This study is following 16,000 who started in childhood and are now adults (40 years thus far). Researchers have looked at several things, on those living, as well as performing autopsies on 560 of these individuals who died since then (of accidental death or otherwise). 20% of autopsied children had plaques (fat deposits) in their coronary arteries, making this the first study of its kind to establish heart disease can exist in children, and those who were obese as children were likely to remain so in adulthood, as opposed to only 7% becoming obese who were not so in childhood.

A DVT (deep vein thrombosis) clinic had 320 persons appearing for lower extremities Doppler ultrasound study. If 48 out of 80 subjects with DVT tested positive for the DVT, and 228 out of 240 without DVT tested negative Calculate the following False negative Positive predictive value (PPV) What does this PPV mean Negative predictive value (NPV)
1) Do you think eliminating the ultrasound is the best choice when it comes to the threat of a clot that could potentially break off at any point and travel to the heart or brain? 2) How effective do you think the pretest probability along with the D-Dimmer test would actually be?
he first involved an assessment of the relationship between cigarette smoking and incidence of lung cancer. For cigarette smokers, the lung cancer incidence rate was Ie = 200 per 100,000. For nonsmokers, the lung cancer incidence rate was Io = 25 per 100,000. The lung cancer incidence rate in the entire population was It = 100 per 100,000. The second study involved an assessment of the relationship between cigarette smoking and incidence of coronary heart disease. For cigarette smokers, the coronary heart disease incidence rate was Ie = 500 per 100,000. For nonsmokers, it was Io = 250 per 100,000. In the overall population, the coronary heart disease rate was It = 300. 1. What is relative risk the of developing lung cancer in the first study and of developing coronary heart disease in the second study? Interpret. 2. From the data involving cigarette smoking and lung cancer incidence, what are the attributable risk and the attributable-risk percent? Interpret the result. 3. From the…

A researcher is conducting an experiment testing whether a new pharmaceutical drug is able to effectively treat heartburn and has a physician assisting with the study involving volunteers who experience chronic heartburn. Which of the following descriptions most closely describes the control used in this study? Show answer choices The researcher has organized the patients into 4 groups, where patients either take 1 dose of the drug, 2 doses of the drug, 1 dose of the placebo, or 2 doses of the placebo. The physician asks patients to rate their heartburn discomfort on a scale from 1-10 every 5 minutes up to an hour. The physician and patients both do not know if they are receiving the actual drug or a placebo. The placebo pill contains just compressed sugar and no active drug. Patients are randomly selected and placed into the four categories.

Out of the experimental designs, two-group pretest-posttest design, two-group posttest design, Solomon four-group design, multiple experimental group design, and factorial design.

I think the most significant thing I learned is the amount of trust that is needed between the public and public health officials. It is a fragile balance that can be shattered with one wrong step by public health officials. In fact in the midst of the pandemic, only about 25% of people greatly trusted their local and state public health departments, with the majority only somewhat trusting them (SteelFisher et al., 2023). In many of the cases we looked at, distrust within the public usually seemed to make recovery harder, and not enough was done to restore trust. The rising rates of gun violence and mass shootings are a grim testament to the failures of the country's leadership. Since each state has its own laws, there is variability when collecting data on firearm-related deaths, but collectively as a nation, there are nearly 10,000 Years of Potential Life Lost (Jehan et al., 2018). Many attempts have been made to pass stricter gun laws, but only a few have been put into effect even…
The Zoomland epidemic does not mimic a real epidemic in every respect. What is ONE way the Zoomland epidemic is not an entirely realistic simulation? A. In the Zoomland epidemic we could tell who had interacted with whom (contact tracing). In real life there is no way to do any contact tracing. B. In the Zoomland epidemic people interacted randomly with others. In real life people interact much more with some members of the population than others. C. In the Zoomland epidemic, transmission only occurred when a person came into contact with an infected person AND a suitable vector. In real life some diseases do not require a vector for successful transmission.
