STUDY DESCRIPTIONS
1.To test the efficacy of a health education program in reducing the risk of foodborne and waterborne diseases, two Peruvian villages were given an intensive health education program. At the end of the two years the incidence rates of important foodborne and waterborne diseases in these villages were compared to those in two similar control villages where no health education programs had been implemented.
2.You would like to assess the effectiveness and efficiency in delivering health services through your clinic. After selecting a 10% sample of all patient visits during the past six months, you are able to characterize the patient population utilizing your clinic in terms of age, race, sex, method of referral, diagnostic category, therapy provided, method of payment, daily patient load, and clinic work schedules.
3.You are interested in finding out whether middle-aged men who have premature heartbeats are at greater risk of developing a myocardial infarction (heart attack) than those men whose heartbeats are regular. Electrocardiogram (ECG) examinations are performed on all male employees 35 years and older who work for an oil company in your city. The ECG tracings are classified as regular or irregular by a trained cardiologist. Five years later, the heart attack rates are compared for between those with and those without baseline ECG irregularities.
4.To test the efficacy of Vitamin C in preventing colds, army recruits are randomly assigned to two groups: one in which 500 mg. of Vitamin C is administered daily, and one in which 500 mg. of placebo is administered daily. Both groups are followed to determine the number and severity of subsequent colds.
5.The physical exam records of the incoming freshmen of 1935 at the University of Minnesota are examined in 1980 to see if their recorded height and weight at the time of their admission to the university are related to their risk of developing coronary heart disease by 1981.
6.The entire population of a given community is examined and all who are judged to be free of bowel cancer are questioned extensively about their diets. These people are then followed for several years to see whether or not their eating habits will predict their risk of developing bowel cancer.

O a. Absorption rates vary widely among individuals, presenting a challenge in prescribing the best dosage.

Explanation:

Bipolar disorder is a mental disorder associated with changes in mood, concentration, and energy in individuals suffering this condition. Lithium is one of the most commonly used medications for the treatment of the bipolar disorder. Lithium is a mood stabilizer that directly acts on the central nervous system, modulating mood and behavior. It has been shown that lithium significantly reduces the risk to suffer acute manic and depressive episodes in individuals with bipolar disorder. Lithium is absorbed through the stomach and excreted in the urine, but there are factors that influence its absorption rate (e.g., ingestion of foods tends to increase lithium absorption), and side effects seem to be associated with the rate of increase in serum lithium concentrations. In general, side effects related to the use of lithium medication can be overcome by adjusting the dose (always under the guidance of a healthcare professional).
