  • Vitamin E Deficiency: Treatment Symptomatic vitamin E deficiency should be treated with 800–1200 mg of αtocopherol per day. Patients with abetalipoproteinemia may need as much as 5000–7000 mg/d. Children with symptomatic vitamin E deficiency should be treated with 400 mg/d orally of water-miscible esters; alternatively, 2 mg/kg per d may be administered intramuscularly. Vitamin E in high doses may protect against oxygen-induced retrolental fibroplasia and bronchopulmonary dysplasia, as well as intraventricular hemorrhage of prematurity.

  • Harrison's Internal Medicine Chapter 71. Vitamin and Trace Mineral Deficiency and Excess Vitamin and Trace Mineral Deficiency and Excess: Introduction Vitamins and trace minerals are required constituents of the human diet since they are either inadequately synthesized or not synthesized in the human body. Only small amounts of these substances are needed for carrying out essential biochemical reactions (e.g., acting as coenzymes or prosthetic groups).

  • Most research in robotics centers on the control and equations of motion for multiple link and multiple degree-of-freedom armed, legged, or propelled systems. A great amount of effort is expended to plot exacting paths for systems built from commercially available motors and motor controllers. Deficiencies in component and subsystem performance are often undetected until the device is well past the initial design stage.

  • Vitamins and trace minerals are required constituents of the human diet since they are either inadequately synthesized or not synthesized in the human body. Only small amounts of these substances are needed for carrying out essential biochemical reactions (e.g., acting as coenzymes or prosthetic groups). Overt vitamin or trace mineral deficiencies are rare in Western countries due to a plentiful, varied, and inexpensive food supply; however, multiple nutrient deficiencies may appear together in persons who are chronically ill or alcoholic.

  • Since the cost of manufacturing a custom train part on a small-scale 3D printer is only $25, Kendrick’s niche market of loyal consumers can afford to manufacture their own train parts -- no investment in factory-scale production is needed. Imagine if a model train enthusiast purchased Kendrick’s electronic blueprint and tried to produce the stainless steel train cowcatcher (shown in the figure) in a factory. The high cost of setting up a factory infrastructure would be well out of the reach of the average consumer.

  • Nutrition is one of those subjects which comes up every day in general practice—or should do—yet in most undergraduate medical schools it is crowded out by the big clinical specialities and high technology procedures. It is for subjects like nutrition that the British Medical Journal’s ABC series is extremely useful. This book was started when Dr Stephen Lock, previous editor of the BMJ asked me to write a series of weekly articles for an imagined general practitioner, in an unfashionable provincial town who had been taught almost no nutrition at medical school.

  • Magnesium deficiency is very often present and quite severe. Hyperreflexia, muscle twitches, myocardial irritability, poor stamina and recurrent tight muscle spasms are clues to this deficiency. Magnesium is predominantly an intracellular ion, so blood level testing is of little value. Oral preparations are acceptable for maintenance, but those with severe deficiencies need additional, parenteral dosing: 1 gram IV or IM at least once a week until neuromuscular irritability has cleared. Pituitary and other endocrine abnormalities are far more common than generally realized.

  • After more than a quarter century as a primary care educator, I am convinced that our graduates enter practice inadequately trained in the diagnosis and management of musculoskeletal problems and injuries. One reason for this perceived deficiency is the relatively short duration of primary care training—typically three years for family medicine, general internal medicine, and general pediatrics. During this time, there are just not enough months to teach all a clinician needs to know about diseases and trauma involving the musculoskeletal system....

  • Visual Acuity The Snellen chart is used to test acuity at a distance of 6 m (20 ft). For convenience, a scale version of the Snellen chart, called the Rosenbaum card, is held at 36 cm (14 in) from the patient (Fig. 29-1). All subjects should be able to read the 6/6 m (20/20 ft) line with each eye using their refractive correction, if any. Patients who need reading glasses because of presbyopia must wear them for accurate testing with the Rosenbaum card. If 6/6 (20/20) acuity is not present in each eye, the deficiency in vision must be...

  • There is no doubt that the protection of women during pregnancy and lactation must be one of the major priorities of health systems and social policies. The effect of women’s nutritional status on pregnancy outcomes is particularly strong, and adequate maternal nutrition is closely related to the survival and well-being of babies and children. However, not all women are mothers, and their nutritional and health needs go far beyond motherhood and reproduction. Women of all ages in developing countries face elevated risks of nutritional deficiencies.

  • From John Glenn s mission to orbit Earth to the International Space Station program, space food research has met the challenge of providing food that tastes good and travels well in space. To better understand this process, we can look back through history. Explorers have always had to face the problem of how to carry enough food for their journeys. Whether those explorers are onboard a sailing ship or on the Space Shuttle, adequate storage space has been a problem.

  • Following their lipophilicity, it is more plausible that vitamin E and ß-carotene cooperate to protect membranes and lipoproteins from oxidative damages. Of course, as all antioxidants, vitamin E exerts other biological functions that are independent from its antioxidant properties, including modulation of cellular signaling, gene expression, immune response, and many more. However, as opposed to other vitamins, lack of vitamin E results in rather unspecific symptoms, also highlighting that this vitamin is mainly needed for its antioxidant activity in vivo.

  • Experts have made recommendations to incorporate nutrition as an essential component of primary health care, stressing that programs to deal with women’s nutritional problems must be based on a life cycle approach. The nutritional needs of women substantially change during the different stages of their lives. A life cycle approach allows a better recognition of specific nutritional needs at every stage of women’s lives, as well as a more comprehensive understanding of the cumulative effects of poor nutrition on women’s health.

  • Available information shows that the nutritional status of Mexican women differs widely within the country, according to geographical regions, urban and rural areas, and income groups. Nutritional deficiencies, anaemia and stunting, for example, are more common in poor women who live in the less-developed regions of the country, in rural and indigenous communities or in marginal urban areas. On the other hand, overweight and obesity currently affect women of all income groups, but rates are higher in the more economically advanced regions and big cities.

  • Although the former NOP director attributed the agency’s inability to effectively act on investigations and issue enforcement actions to a lack of resources, we determined that several other factors contributed to this deficiency. We noted, for instance, that NOP lacked procedures for receiving, reviewing, and maintaining reports of investigations from AMS Compliance. In addition, NOP did not establish a specific written process, including timeframes, for determining which enforcement actions are appropriate and for initiating and completing such actions in a timely manner.

  • Nutritional Dietary folate deficiency is common. Indeed, in most patients with folate deficiency a nutritional element is present. Certain individuals are particularly prone to have diets containing inadequate amounts of folate (Table 100-5). In the United States and other countries where fortification of the diet with folic acid has been adopted, the prevalence of folate deficiency has dropped dramatically and is now almost restricted to high-risk groups with increased folate needs.
