Cohort study

Cohort groups were comprised of the total of 121,956 COPD patients with the age range from 45 to 80-years old who were also receiving the BB treatment. Of the 15 studies, 5 studies included only COPD patients with concomitant coronary heart disease (CHD) including angina pectoris and MI and the other 3 studies evaluated only COPD patients with the heart failure (HF). The duration of the treatment among studied participants ranged from 1 year to 7.2 years.1 The researchers observed that the BB use was associated with the significantly lowered mortality risk (RR 0.72; 95% CI=0.63 to 0.83) and COPD exacerbation (RR 0.63; 95% CI=0.57 to 0.71); (p = 0.00001).1 The decrease in the mortality risk was even greater in coronary artery disease (CAD), (RR 0.64; 95% CI=0.54 to 0.76) and HF (RR 0.74; 95% CI=0.58 to 0.93).1 In COPD patients, the sympathetic nervous system (SNS) is more active and thus associated…

Swedish women? Does the background section summarize all the relevant research about this topic? Yes, the background section did in fact summarize the relevant research about this topic. Does it make a clear case for why the research is important? The research does clearly state why the research was important. The study could be compared to other studies about the relationship between coffee consumption and incidence of diabetes in women. 2. Methods Was the study a primary, secondary or…

Guinn_ENVM510_M4GradedAssign – Sunday 1. Prophylactic antibiotic study: The variable of timing considered. Background: Preventing infection in surgical patients with prophylactic antibiotics uses overall less antibiotics than treating a patient post-surgery who have developed an infection (Burke, 2001). These results indicate an overall reduction in infections, which reduce the overall use of antibiotics. The variable that is critical in the effectiveness of prophylactic antibiotic use is…

Context for Longitudinal Study Using Competing Risk Approaches Despite the fact that the effectiveness of RAAS inhibitors in the primary prevention of AF has been evaluated by several population-based observational studies [23-25], it is not clear whether the RAAS inhibitors remain effective in the reduction of new-onset AF in the older adult hypertensive population when competing risks (e.g. all-cause death) exist. All of these studies simply ignored the existence of the competing risks in…

Question 1: What makes the first study a case-control study? The first study is a case control study. According Leon Gordis in a case control study, to examine the possible relation of an exposure to a certain disease (cases) and, for purposes of comparison, a group of people without that disease (controls). In the first study the individuals with the disease who were smokers (cases) and individuals who were smokers with a different disease diagnosis (controls). Question 2: What makes the…

One of many strengths of a cohort study include the ability to examine multiple outcomes from a given exposure or multiple exposures from a defined population (Gordis, 2013). One can also gather data regarding the sequence of events, known as the temporal relationship, and therefore, assess the strength of association and other parameters through absolute, relative, and attributable risk (Gordis, 2013). Moreover, cohort studies are best known for investigating rare exposures and rates of disease…

The study used only quantitative methods to collect data, that came from the fourth sweep of the Millennium Cohort Study (MSC). The article describes the Millennium Cohort Study as a longitudinal birth cohort study, which offers a large-scale information about the ‘New Century Children’ and their family in the UK. The sample for the surveys was a clustered and disproportionately stratified. The sample selection is adequate and has a clear rationale, as it include children born in UK in 2000/01…
