OET PART B READING - All life is connected

All Life is Connected Cancer in Humans and Wildlife Janette D. Sherman, MD (2000) Life's Delicate Balance: Causes and Prevention of Breast Cancer. [Copyright permission has been granted to use this work as material for a reading exercise.] Man has lost the ability to foresee and to forestall. He will end by destroying the earth. -Albert Schweitzer, quoted in Silent Spring

WILDLIFE-HUMAN LINKS It may be that biologists, rather than physicians, will be the major contributors to the health of our planet and its people. It was Rachel Carson, a biologist, who researched and wrote of the harm to wildlife caused by the combined action of pesticides and radiation. In the tradition of the observant biologist is Theo Colborn, who, with her colleagues, provided a significant breakthrough in understanding the hormonal effects of environmental contaminants. In July 1991, a gathering of some of the world's most astute scientists was held at the Wingspread Conference Center in Wisconsin,1 where they defined the pattern of diverse endocrine malfunction seen throughout the animal kingdom. They revealed a picture of the Brave New World we should rigorously seek not to leave as a legacy to our children. The conferees, studying wildlife over the globe, described ominous findings of disease and death linked to environmental pollution. Exposure to toxic chemicals that possess unintended hormonal actions has resulted in anatomic, physiologic, reproductive, carcinogenic, and behavioral abnormalities across all forms of animal life: in mollusks, fish, birds, seals, and rodents. These creatures are to we humans as canaries were to the miners. We must understand that the destruction of eons of evolutionary function and development in wildlife foreshadows destruction of the entire biosphere, humans included. These widespread adverse effects were attributed to xenoestrogens. Xeno- comes from a Greek origin, meaning "foreign." Foreign itself is not bad: how else do we share and spread culture and ideas? But xenoestrogens are less foreigners than invaders, gaining entrance by the Trojan horse of seemingly harmless routes: milk, meat, cheese, fish, the products we use to nourish ourselves and families. Like the invaders of Troy, after the xenoestrogens gain entrance to the bodies of animals and humans alike, they weaken defences and wreak their harm of cancer, hormonal disruption, immunological abnormalities, and birth defects. Xenoestrogens are an insidious enemy, but they have had help from powerful allies: the purveyors of products and chemicals, and legislators, regulators, and scientists reluctant to bite the moneyladen hands that feed them.

OET PART B READING - All life is connected

Wingspread researchers found that birds exposed to xenoestrogens show reproductive failure, growth retardation, life-threatening deformities, and alterations in their brains and liver function.2 "There is direct experimental evidence for permanent [organizational] effects of gonadal steroids on the brain as well as reproductive organs throughout life."3 This means that offspring whose brains have been altered are unable to function as had their parents. They become different in ability or function. This means that the sea of hormonally active chemicals in which the fetus develops may change forever the health and function of the adult, and in some cases, may alter the course of an entire species.4 Worldwide there are reports of declining sperm counts5 and reduced ratio in births of male babies.6 Without the capacity to reproduce, a species ceases to exist. Extinction is forever; a species loss has never been reversed. The data derived from animal observations are unequivocal: breast and genital cancers, genital abnormalities, interference with sexual development, and changes in reproductive behavior are all expressions of a root cause. A possible connection between women with breast cancer and those having children with reversed sexual orientation is a question that bears study. This is not an idea from science fiction, considering what we have learned from observing wildlife and the effects of inappropriate hormonal influence upon the breast, brain, and reproductive organs. If an unequivocal answer were to emerge from human observation, it could have a significant impact upon the prevailing political and economic landscape, and may finally settle the nature or nurture issue of sexual orientation. SILENT SPRING-SILENT WOMEN Considering the accumulated knowledge linking chemical and radioactive contamination of the environment with increasing breast cancer rates means we must focus our energies and efforts on prevention. Early were the eloquent words and pleas for prevention from Rachel Carson. Her book, Silent Spring, originally published in 1962, while she herself was suffering from breast cancer, is still a bestseller. Ms. Carson documented wholesale killing of species; animals, birds, fish, insects; the destruction of food and shelter for wild creatures; failure of reproduction; damage to the nervous system; tumors in wild animals; increasing rates of leukemia in children; and chronicled the pesticides and chemicals known at that time to cause cancer. This was over 30 years ago! Carson's is a book for every citizen, for without understanding of our collective actions and permissions, we cannot govern democratically. In Australia, a citizen is required to vote. In the United States, proclaimed by some politicians as the "greatest democracy on earth," often fewer than 50% bother to vote in a major election. Of those who do take the time to register and vote, few are sufficiently alert and/or educated to vote with intelligence, thought, and compassion. Requiring participation in the governance of one’s own country is not a bad idea. Requiring thoughtful voting may be more difficult, especially when it comes to such issues as cancer, pesticide use, consumer products, nuclear radiation, toxic chemicals, and environmental destruction. Taking this thought one step further, this democracy could do far worse than to require reading of Silent Spring as a requirement to vote! Radical? Perhaps. But is the ongoing cancer epidemic any less radical?

OET PART B READING - All life is connected

One successor to Ms. Carson has emerged in the person of Sandra Steingraber, an ecologist, poet, and scientist. In her book, Living Downstream, she writes eloquently of the connections between environmental contamination and cancer. Dr. Steingraber was diagnosed with bladder cancer at age 20, a highly unusual diagnosis in a woman, a young woman, a nonsmoker and nondrinker. She pursued the question, why? She realized a connection with our wild relations and she asks: Tell me, does the St. Lawrence beluga drink too much alcohol and does the St. Lawrence beluga smoke too much and does the St. Lawrence beluga have a bad diet . . . is that why the beluga whales are ill? . . . Do you think you are somehow immune and that it is only the beluga whale that is being affected?7 The portion of Dr. Steingraber's book that struck me most personally was when she says: First, even if cancer never comes back, one's life is utterly changed. Second, in all the years I have been under medical scrutiny, no one has ever asked me about the environmental conditions where I grew up, even though bladder cancer in young women is highly unusual. I was once asked if I had ever worked with dyes or had been employed in the rubber industry. (No and no.) Other than these two questions, no doctor, nurse, or technician has ever shown interest in probing the possible causes of my disease-even when I have introduced the topic. From my conversations with other cancer patients, I gather that such lack of curiosity in the medical community is usual .8 I take her words as an indictment of the medical and scientific establishment, whose point of view must be changed. Certainly the lack of curiosity among physicians, scientists, policymakers, and politicians has contributed to the epidemic of illness among humans and wildlife alike. An equally talented woman is Terry Tempest Williams, an ecologist and wildlife researcher, whose book, Refuge: An Unnatural History of Family and Place, tells the story of her Utah family, whom she labels "a clan of one-breasted women." Ms. Williams contrasts the life-affirming awareness of the Great Salt Lake wildlife refuge against the erosion-of-being, as cancer takes away the women in her family: her mother, her grandmothers, and six aunts. She writes: "I cannot prove that my mother Diane Dixon Tempest, or my grandmothers, Lettie Romney Dixon and Kathryn Blackett Tempest, along with my aunts, developed cancer from nuclear fallout in Utah. But I can't prove that they didn't."9 Times are changing. It is becoming impossible to ignore the carnage of endocrine-disrupting chemicals, nuclear radiation, and chemical carcinogens, alone and in combination, invading nearly every family with cancer. Facing this reality may be too much for some people, afraid to look, or afraid of being the next victim. The story of cancer is not an easy one, and neither is cancer. But if we do not exert our efforts to prevent this disease, we doom our children and grandchildren to repeat our collective errors. What does it take to change from environmental destruction and random killing to affirmation of life? Can the protection of life for ourselves and our environment be accomplished by women with breast cancer; the women at risk for breast cancer; the families of breast cancer victims? Who should lead? If we citizens can't and don't try, what are our alternatives?

Tufts University faculty debunks common dental myths 7 August 2010 02:39 Brushing, flossing, and twice-yearly dental check-ups are standard for oral health care, but there are more health benefits to taking care of your pearly whites than most of us know. In a review article, a faculty member at Tufts University School of Dental Medicine (TUSDM) debunks common dental myths and outlines how diet and nutrition affects oral health in children, teenagers, expectant mothers, adults and elders. Myth 1: The consequences of poor oral health are restricted to the mouth Expectant mothers may not know that what they eat affects the tooth development of the fetus. Poor nutrition during pregnancy may make the unborn child more likely to have tooth decay later in life. "Between the ages of 14 weeks to four months, deficiencies in calcium, vitamin D, vitamin A, protein and calories could result in oral defects," says Carole Palmer, EdD, RD, professor at TUSDM and head of the division of nutrition and oral health promotion in the department of public health and community service. Some data also suggest that lack of adequate vitamin B6 or B12 could be a risk factor for cleft lip and cleft palate formation. In children, tooth decay is the most prevalent disease, about five times more common than childhood asthma. "If a child's mouth hurts due to tooth decay, he/she is less likely to be able to concentrate at school and is more likely to be eating foods that are easier to chew but that are less nutritious. Foods such as donuts and pastries are often lower in nutritional quality and higher in sugar content than more nutritious foods that require chewing, like fruits and vegetables," says Palmer. "Oral complications combined with poor diet can also contribute to cognitive and growth problems and can contribute to obesity." Myth 2: More sugar means more tooth decay It isn't the amount of sugar you eat; it is the amount of time that the sugar has contact with the teeth. "Foods such as slowly-dissolving candies and soda are in the mouth for longer periods of time. This increases the amount of time teeth are exposed to the acids formed by oral bacteria from the sugars," says Palmer. Some research shows that teens obtain about 40 percent of their carbohydrate intake from soft drinks. This constant beverage use increases the risk of tooth decay. Sugar-free carbonated drinks and acidic beverages, such as lemonade, are often considered safer for teeth than sugared beverages but can also contribute to demineralization of tooth enamel if consumed regularly. Myth 3: Losing baby teeth to tooth decay is okay It is a common myth that losing baby teeth due to tooth decay is insignificant because baby teeth fall out anyway. Palmer notes that tooth decay in baby teeth can result in damage to the developing crowns of the permanent teeth developing below

OET PART B READING them. If baby teeth are lost prematurely, the permanent teeth may erupt malpositioned and require orthodontics later on. Myth 4: Osteoporosis only affects the spine and hips Osteoporosis may also lead to tooth loss. Teeth are held in the jaw by the face bone, which can also be affected by osteoporosis. "So, the jaw can also suffer the consequences of a diet lacking essential nutrients such as calcium and vitamins D and K," says Palmer. "The jawbone, gums, lips, and soft and hard palates are constantly replenishing themselves throughout life. A good diet is required to keep the mouth and supporting structures in optimal shape." Myth 5: Dentures improve a person's diet If dentures don't fit well, older adults are apt to eat foods that are easy to chew and low in nutritional quality, such as cakes or pastries. "First, denture wearers should make sure that dentures are fitted properly. In the meantime, if they are having difficulty chewing or have mouth discomfort, they can still eat nutritious foods by having cooked vegetables instead of raw, canned fruits instead of raw, and ground beef instead of steak. Also, they should drink plenty of fluids or chew sugar-free gum to prevent dry mouth," says Palmer. Myth 6: Dental decay is only a young person's problem In adults and elders, receding gums can result in root decay (decay along the roots of teeth). Commonly used drugs such as antidepressants, diuretics, antihistamines and sedatives increase the risk of tooth decay by reducing saliva production. "Lack of saliva means that the mouth is cleansed more slowly. This increases the risk of oral problems," says Palmer. "In this case, drinking water frequently can help cleanse the mouth." Adults and elders are more likely to have chronic health conditions, like diabetes, which are risk factors for periodontal disease (which begins with an inflammation of the gums and can lead to tooth loss). "Type 2 diabetes patients have twice the risk of developing periodontal disease of people without diabetes. Furthermore, periodontal disease exacerbates diabetes mellitus, so meticulous oral hygiene can help improve diabetes control," says Palmer. Source: Tufts University, Health Sciences
