  • Harrison's Internal Medicine Chapter 4. Screening and Prevention of Disease Screening and Prevention of Disease: Introduction A primary goal of health care is to prevent disease or to detect it early enough that intervention will be more effective. Strategies for disease screening and prevention are driven by evidence that testing and intervention are practical and effective. Currently most screening tests are readily available and inexpensive. Examples include tests that are biochemical (e.g., cholesterol, glucose), physiologic (e.g., blood pressure, growth curves), radiologic (e.g.

  • The U.S. Preventive Services Task Force (USPSTF) provides recommendations for evidence-based screening (Table 4-3). In addition to these population-based guidelines, it is reasonable to consider family and social history to identify individuals with special risk ( For example, when there is a significant family history of breast, colon, or prostate cancer, it is prudent to initiate screening about 10 years before the age when the youngest family member developed cancer.

  • Screening is performed earlier and more frequently when there is a strong family history. Randomized, controlled trials have documented that fecal occult blood testing (FOBT) confers a 15 to 30% reduction in colon cancer mortality. Although randomized trials have not been performed for sigmoidoscopy or colonoscopy, well-designed case-control studies suggest similar or greater efficacy relative to FOBT. b In the future, Pap smear frequency may be influenced by HPV testing and the HPV vaccine.

  • Carl, the owner of the Jackson Eagles, punched a button on the remote control. “Just look at this,” he said. Ed, the coach, turned to watch. On the screen, a player with floppy blond hair twisted away from a guard and scored. His moves were amazingly quick. “Yeah, Dale Curtis,” Ed said. “I’ve seen him. I don’t want him.” “Come on, man!” Carl said. “He could be the next Larry Bird!” “He’s a problem waiting to happen,” Ed said. “The kid is only 18, just out of high school.

Of his First Guerrilla Regiment, General Douglas MacArthur stated that "He had acquired a force behind the Japanese lines that would have a far reaching effect on the war in the days to come"; that it had kept "Freedom's Flames burning brightly throughout the Philippines"; that it had produced a "human drama with few parallels in military history"; and later, during the landing in Lingayen Gulf, had "accomp...

  • Information asymmetry can be reduced via three ways: a firm’s ability to signal its credit worthiness (incl. an institutional assessment or rating by an independent agency and the provision of collateral), a strong relationship between lender and borrower, and through due diligence/lenders’ examination (screening). However, this means on the other hand that new or young firms, with a lack of collateral and by definition without track record are the ones with the greatest degree of difficulty accessing debt capital (Equinox, 2002).

  • Chapter 004. Screening and Prevention of Disease Examples include tests that are biochemical (e.g., cholesterol, glucose), physiologic (e.g., blood pressure, growth curves), radiologic (e.g., mammogram, bone densitometry), or tissue specimens (e.g., Pap smear, fine-needle aspirations). In the future, it is anticipated that genetic testing will play an increasingly important role for predicting disease risk (Chap. 64). However, such tests are not widely used except for individuals at risk for high-penetrance genes based on family or ethnic history (e.g., BRCA1, BRCA2).

  • In ancient Greece, people would journey to an oracle, or fortune teller, to discover what the future held. The oracle would kill an animal, perhaps a goat or a sheep, to examine the creature’s liver. A dark red liver that was smooth was a good sign. A pale liver that was bumpy foretold bad times ahead. The liver has long been linked to human courage and strength. The earliest doctors thought that the liver was one of the three main organs of the body. The others were the heart and the brain. Around a.d. 200, the famous Roman doctor Galen declared the liver to be the most important human...

  • In short, risks increase if the bank considers the synthetic ETF structure as a stable and inexpensive source of funding for illiquid securities. ETF investors may not always have sufficient control over collateral arrangements to enable them to prevent such a situation. More broadly, investors in synthetic ETFs need to exercise an adequate level of scrutiny and due diligence on collateral selection and arrangements, which in turn depends on the level of transparency made available by ETF providers.

  • It is possible that once efficient human-to-human transmission of H5N1 occurs certain countries may close their borders sporadically believing (rightly or wrongly) that this measure would be effective in reducing the spread of influenza. Screening (with quarantine measures) could be established at borders. If justified by risk/benefit analysis it may be advisable to request employees to consider postponing non-essential travel outside Canada when the pandemic starts. Arrangements may also be required for employees who are stranded outside of the country because borders are closed.

  • Late in the expansion phase (December 2003), the screening test was adjusted to add VILI as part of the algorithm. This was done after experience at the district hospital level and the completion of international studies involving more than 55,000 women in Asia and Africa showed VILI to be easier to interpret and significantly more sensitive than VIA. 10 Lugol’s iodine stains normal cervix tissue brown, while precancerous lesions (CIN) and cancerous lesions appear as a mustard yellow color.

  • Screening interventions should ideally be delivered through primary health care or as close to the community as possible. In countries where other vertical programmes for sexual and reproductive health, sexually transmitted infections (STI), oncology, and/or adolescent and youth services exist, cervical cancer prevention should be integrated into these services. Developing a new vertical programme specifically for cervical cancer prevention should be avoided.
