Early cross-cultural and case-control studies reported strong associations between total fat intake and breast cancer (Howe et al cheap 250 mg terramycin with amex. Evidence from epidemiological studies on the relationship between fat intake and colon cancer has been mixed as well (De Stefani et al discount terramycin 250 mg visa. Howe and colleagues (1997) reported no asso- ciation between fat intake and risk of colorectal cancer from the com- bined analysis of 13 case-control studies buy terramycin 250 mg without a prescription. Epidemiological studies tend to suggest that dietary fat intake is not associated with prostate cancer (Ramon et al. Giovannucci and coworkers (1993), however, reported a positive association between total fat consumption, primarily animal fat, and risk of advanced prostate cancer. Findings on the association between fat intake and lung cancer have been mixed (De Stefani et al. Numerous mechanisms for the carcinogenic effect of dietary fat have been proposed, including eiconasanoid metabolism, cellular prolifera- tion, and alteration of gene expression (Birt et al. Experimental evidence suggests several mechanisms in which n-3 fatty acids may protect against cancer. Epidemiological studies have shown an inverse relationship between fish consumption and the risk of breast and colorectal cancer (Caygill and Hill, 1995; Caygill et al. Monounsaturated fatty acids have been reported as being protective against breast, colon, and possibly prostate cancer (Bartsch et al. However, there is also some epidemiological evidence for a positive asso- ciation between these fatty acids and breast cancer risk in women with no history of benign breast disease (Velie et al. There may be protective effects associated with olive oil (Rose, 1997; Trichopoulou et al. Dietary Carbohydrate While the data on sugar intake and cancer are limited and insufficient, several case-control studies have shown an increased risk of colorectal cancer among individuals with high intakes of sugar-rich foods (Benito et al. Additionally, high vegetable and fruit consumption and avoidance of foods containing highly refined sugars were shown to be negatively correlated to the risk of colon cancer (Giovannucci and Willett, 1994). Dietary Fiber There is some evidence based on observational and case-control studies that fiber-rich diets are protective against colorectal cancer (Lanza, 1990; Trock et al. There is also some epidemiological evidence of a pro- tective effect of cereals and cereal fiber against colon carcinogenesis (Hill, 1997). Despite these and other positive findings, a number of important studies (Fuchs et al. High-fiber diets may also be protective against the development of colonic adenomas (Giovannucci et al. However, not all studies have found a significant association between the dietary intake of total, cereal, or vegetable fiber and colorectal adenomas, although a slight reduction in risk was observed with increasing intake of fruit fiber (Platz et al. There are numerous hypotheses as to how fiber might protect against the development of colon cancer. These include the dilution of carcino- gens, procarcinogens, and tumor promoters in a bulky stool; a more rapid rate of transit through the colon with high-fiber diets; a reduction in the ratio of secondary bile acids to primary bile acids by acidifying colonic contents; the production of butyrate from the fermentation of dietary fiber by the colonic microflora; and the reduction of ammonia, which is known to be toxic to cells (Harris and Ferguson, 1993; Jacobs, 1986; Klurfeld, 1992; Van Munster and Nagengast, 1993; Visek, 1978). Recent studies have shown a decreased risk of endome- trial cancer (Barbone et al. Although fiber has the ability to decrease blood estrogen concentra- tions by a variety of different mechanisms (Rose et al. Half of the epidemiological studies attempting to link low dietary fiber intake to breast cancer have failed to show this relationship (Gerber, 1998). The data on cereal intake and breast cancer risk are considerably stronger than overall fiber intake (Rohan et al. Physical Activity Regular exercise, as recommended in this report, has been shown to be negatively correlated with the risk of colon cancer (Colbert et al. This is, in part, due to the reduction in obesity, which is positively related to cancer (Carroll, 1998). In men and women who are physically active, the risk of colon cancer is reduced by 30 to 40 percent compared with those who are sedentary. However, relatively few studies found a consistent association between physical activity and decreased incidence of endome- trial cancer. For prostate cancer, results of about 20 studies were less consistent, with only moderately strong relationships. With regard to the possible effect of exercise on other forms of cancer, such as pancreatic cancer (Michaud et al. The role of diet in the promotion or prevention of heart disease is the subject of considerable research. New studies investigating dietary energy sources and physical activity for their potential to alter some of the risk factors for heart disease are underway (i.

Children add a dimen- sion to life that is unique and delightful, and the parental role Unique challenges of parenting provides opportunities to know ourselves better. That being Physician parents are in an unique position as they promote said, parenting can add to the complexity of managing busy and monitor their children’s health and development. Where some may argue that knowledge about health is valuable and helpful, but—as is the physician parents lack full professional commitment, others case with any parent—their objectivity is limited. Issues that they ensure their children have a primary care provider confronting physician parents are many, and their complexities who is skilled and comfortable working with the dynamics concern both professional and personal roles. It is also essential that physicians avoid boundary crossings or violations with their children; only in Parental leave emergencies should they assume a direct clinical role; other- Every provincial housestaff organization has negotiated paren- wise, they should join in a collaborative relationship with their tal leave policies for their members, and many directly address child’s physician and their child.

Decreased interest in activities that were once enjoyed during free time leads to social withdrawal and personal isolation. However, the profession of medicine is demanding, and it is Relationships with family and friends are compromised, and diffcult to put limits around its practice. Poor constant exposure to suffering, heavy workloads, long hours, coping strategies that are adopted might include the increased time pressures, physical and mental demands, and a lack of intake of caffeine and alcohol, or the use of illicit drugs. Physicians are acutely Faced with some or all of these effects, one might experience aware of the distress of others but are often less attentive to at the same time a reduced sense of accomplishment and the stress and fatigue that they experience themselves. It is easy to lose sight of one’s accomplishments caring for others often leads to neglect of oneself. This is the sign of We know that physicians, as a group, are well informed with signifcant stress. We also know that when physicians are overwhelmed by the demands Given that the demands of the profession are ever present, of their profession, they are vulnerable to neglecting those what is the solution?
