  • Nutritional Status Assessment Full nutritional status assessment is reserved for seriously ill patients and those at very high nutritional risk when the cause of malnutrition is still uncertain after initial clinical evaluation and dietary assessment. It involves multiple dimensions, including documentation of dietary intake, anthropometric measurements, biochemical measurements of blood and urine, clinical examination, health history, and functional status. For further discussion of nutritional assessment, see Chap. 72.

  • Occasional injuries are part of the human experience, and healing is the body’s self-repair process. Healing begins with inflammation, which nature uses to clean up damaged tissues and protect against infection. So if inflammation is beneficial, why are so many modern diseases characterized by chronic and unhealthy inflammation? This revised edition of The Inflammation Syndrome answers a major part of this important question.

  • He discovered that the firm’s fundamental factors exercise the most significant impact on stock prices. The EPS was found to be the most influencing factor over the market. Studying the effects of the Iraq war on US financial markets, Rigobon and Sack (2004) discovered that increases in war risk caused declines in Treasury yields and equity prices, a widening of lower-grade corporate spreads, a fall in the dollar, and a rise in oil prices. A positive correlation exists between the price of oil and war. They argue that war has a significant impact on the oil price.

  • Two methods are employed to examine the correlation between the top statutory tax rates and the various measures of economic growth. In both cases, the correlation between two variables is determined; causation, whether changes in one variable cause the other variable to change, is not determined. The top statutory tax rates are marginal tax rates—they indicate the proportion of an additional dollar of income that is paid in federal income tax.

  • Numerous reports, including some from the National Research Council, have examined the relationship of diet to cancer. It is generally accepted that diet is a contributing factor to the onset or progression of some types of cancer and that a prudent selection of foods, including fruits and vegetables, and avoidance or decreased consumption of other foods might influence the risk to an individual of contracting cancer.

  • Preparations derived from Lentinula edodes (Berk.) Pegl. mycelium are worldwide used as dietary supplements containing compounds active as immune system enhancers, demonstrating chemopreventive and anticancer activity. L. edodes mycelium enriched with organic forms of selenium like selenized yeast possess putative, higher cancer preventive properties. The objective of this study was to test the effect of enrichment in selenium on antioxidant, reducing and free radical scavenging activity of water and alcohol extracts from mycelium of L. edodes (Berk.).

  • Approach to the Patient: Constipation A careful history should explore the patient's symptoms and confirm whether he or she is indeed constipated based on frequency (e.g., fewer than three bowel movements per week), consistency (lumpy/hard), excessive straining, prolonged defecation time, or need to support the perineum or digitate the anorectum. In the vast majority of cases (probably 90%), there is no underlying cause (e.g., cancer, depression, or hypothyroidism), and constipation responds to ample hydration, exercise, and supplementation of dietary fiber (15–25 g/d).

  • Ineffective Hemopoiesis There is an accumulation of unconjugated bilirubin in plasma due to the death of nucleated red cells in the marrow (ineffective erythropoiesis). Other evidence for this includes raised urine urobilinogen, reduced haptoglobins and positive urine hemosiderin, and a raised serum lactate dehydrogenase. A weakly positive direct antiglobulin test due to complement can lead to a false diagnosis of autoimmune hemolytic anemia. Causes of Cobalamin Deficiency Cobalamin deficiency is usually due to malabsorption. The only other cause is inadequate dietary intake.

  • However, surveillance data shows that even in years of improved food production and relative stability, rates of acute and chronic malnutrition remain high in certain regions indicating other underlying causes play a significant role. Evidence shows that sub-optimal infant, young child and maternal feeding and care practices, low dietary diversity, poor hygiene, water and sanitation, high morbidity coupled with inadequate access to health care are key determinants of the problem.

  • However, the situational analysis shows that in some regions rates of chronic and acute malnutrition remain high even outside of times of crisis, with multi factorial underlying causes. These underlying causes include: sub optimal infant, young child and maternal feeding and care practices, poor dietary diversity, inadequate water and sanitation and high morbidity coupled with poor access to and utilisation of health services.

  • Alzheimer's disease is a devastating disease whose recent increase in incidence rates has broad implications for rising health care costs. Huge amounts of research money are currently being invested in seeking the underlying cause, with corresponding progress in understanding the disease progression. In this paper, we highlight how an excess of dietary carbohydrates, particularly fructose, alongside a relative deficiency in dietary fats and cholesterol, may lead to the development of Alzheimer's disease.
