Routine Administration of Vitamin K1 Prophylaxis to the Newborn
Routine Administration of Vitamin K1 Prophylaxis to the Newborn Practice Resource for Health Care Providers July 2016 Practice Resource Guide: ROUTINE ADMINISTRATION OF VITAMIN K1 PROPHYLAXIS TO THE NEWBORN The information attached is the summary of the position statement and the recommendations from the recent CPS evidence-based guideline for routine intramuscular administration of Vitamin K1 prophylaxis to the newborn*: www.cps.ca/documents/position/administration-vitamin-K-newborns Summary Vitamin K deficiency bleeding or VKDB (formerly known as hemorrhagic disease of the newborn or HDNB) is significant bleeding which results from the newborn’s inability to sufficiently activate vitamin K-dependent coagulation factors because of a relative endogenous and exogenous deficiency of vitamin K.1 There are three types of VKDB: 1. Early onset VKDB, which appears within the first 24 hours of life, is associated with maternal medications that interfere with vitamin K metabolism. These include some anticonvulsants, cephalosporins, tuberculostatics and anticoagulants. 2. Classic VKDB appears within the first week of life, but is rarely seen after the administration of vitamin K. 3. Late VKDB appears within three to eight weeks of age and is associated with inadequate intake of vitamin K (exclusive breastfeeding without vitamin K prophylaxis) or malabsorption. The incidence of late VKDB has increased in countries that implemented oral vitamin K rather than intramuscular administration. There are three methods of Vitamin K1 administration: intramuscular, oral and intravenous. The Canadian Paediatric Society (2016)2 and the American Academy of Pediatrics (2009)3 recommend the intramuscular route of vitamin K administration. The intramuscular route of Vitamin K1 has been the preferred method in North America due to its efficacy and high compliance rate. -

Received: 24 January 2019; Accepted: 16 February 2019; Published: 19 February 2019 Abstract: Vitamin K is an essential bioactive compound required for optimal body function. Vitamin K can be present in various isoforms, distinguishable by two main structures, namely, phylloquinone (K1) and menaquinones (K2). The difference in structure between K1 and K2 is seen in different absorption rates, tissue distribution, and bioavailability. Although differing in structure, both act as cofactor for the enzyme gamma-glutamylcarboxylase, encompassing both hepatic and extrahepatic activity. Only carboxylated proteins are active and promote a health profile like hemostasis. Furthermore, vitamin K2 in the form of MK-7 has been shown to be a bioactive compound in regulating osteoporosis, atherosclerosis, cancer and inflammatory diseases without risk of negative side effects or overdosing. -
Report on Effects of Beta-Carotene Supplementation in Combination with Tocopherol and Ascorbate in Clinical and Chemopreventive Trials (Adopted by the SCF on 19/3/98)
Report on Effects of Beta-carotene Supplementation in Combination with Tocopherol and Ascorbate in Clinical and Chemopreventive Trials (Adopted by the SCF on 19/3/98) Terms of Reference The committee was asked by the Commission to review on recent reports of the studies on health effects of high doses of beta-carotene, retinol and alpha-tocopherol as well as ascorbate in controlled studies. Introduction Epidemiological studies of the last ten years have indicated that beta-carotene is a potential agent for the chemical prevention against carcinogenesis. In contrast, the recent prospective study performed by Heinonen et al. (1) has strikingly suggested that supplementation with beta-carotene significantly increased the incidence of lung, prostate and stomach cancer. The rising question is the possible dose dependency of a preventive or harmful action of beta-carotene and possible synergistic effects with other antioxidants. To answer this question clinical trials for therapy and intervention studies in healthy populations dealing with beta- carotene supplementation in different dosages below the GRAS daily intake of 200 mg have to be regarded. Clinical trials Therapeutic dosages of beta-carotene applied varied in a relative wide range of 20 mg/d to 180 mg/d. The highest daily dosage of 180 mg beta-carotene in combination with 100.000 IU vitamin A ( 30 mg retinol equivalents) was applied 1988 by Stich et al. (2) in tobacco chewers who had already sustained premalignant leukoplakia. After 6 months the single treatment with beta-carotene induced a significant remission of leukoplakias compared to the placebo group, although the combination of beta-carotene and retinol was much more effective. -
An Abstract of the Thesis Of
AN ABSTRACT OF THE THESIS OF Larry Stanford Merrifield for the M.S. in Food Science (Name) (Degree) (Major) Date thesis is presented June 26, 1964 Titie FACTORS AFFECTING THE ANTIMICROBIAL ACTIVITY OF VITAMIN K 5 Abstract approved (M^jor Tp&Sfesso/) Vitamin K, 4-amino-2-methyl- 1-naphthol hydrochloride, a 5 water soluble analog of vitamin K has been shown to possess an anti- microbial activity toward many bacteria, molds, and yeast. Much of the work reported in the literature is on its use as a food preserva- tive, and it was the purpose of this study to investigate some of the factors which might affect the antimicrobial activity of vitamin K in order to add insight into its more effective use as a food preserva- tive. Pure cultures of Escherichia coli, Bacillus subtilis, Proteus vulgaris, Staphlococcus aureus, and Pseudomonas fluorescens were utilized. The effect of the method of application of vitamin K on Escherichia coli; the effect of purity of vitamin K against Escherichia coli; the bactericidal concentrations required for Escherichia coli, Bacillus subtilis, Proteus vulgaris, Staphlococcus aureus, and Pseudomonas fluorescens; the effect of an absence of oxygen; the effect of contact time with Escherichia coli; the effect of initial count/ml of Escherichia coli; and the synergistic action in combination with propylene glycol were studied. The results demonstrated that air oxidation of vitamin K was 5 necessary to obtain maximum inhibitory activity against Escherichia coli. The use of white, crystalline vitamin K synthesized in the laboratory, as compared to partially oxidized commercial prepara- tions, gave better results against Escherichia coli. -

Vitamins Minerals Nutrients
vitamins minerals nutrients Vitamin B12 (Cyanocobalamin) Snapshot Monograph Vitamin B12 Nutrient name(s): (Cyanocobalamin) Vitamin B12 Most Frequent Reported Uses: Cyanocobalamin • Homocysteine regulation Methylcobalamin • Neurological health, including Adenosylcobalamin (Cobamamide) diabetic neuropathy, cognitive Hydroxycobalamin (European) function, vascular dementia, stroke prevention • Anemias, including pernicious and megaloblastic • Sulfite sensitivity Cyanocobalamin Introduction: Vitamin B12 was isolated from liver extract in 1948 and reported to control pernicious anemia. Cobalamin is the generic name of vitamin B12 because it contains the heavy metal cobalt, which gives this water-soluble vitamin its red color. Vitamin B12 is an essential growth factor and plays a role in the metabolism of cells, especially those of the gastrointestinal tract, bone marrow, and nervous tissue. Several different cobalamin compounds exhibit vitamin B12 activity. The most stable form is cyanocobalamin, which contains a cyanide group that is well below toxic levels. To become active in the body, cyanocobalamin must be converted to either methylcobalamin or adenosylcobalamin. Adenosylcobalamin is the primary form of vitamin B12 in the liver. © Copyright 2013, Integrative Health Resources, LLC | www.metaboliccode.com A protein in gastric secretions called intrinsic factor binds to vitamin B12 and facilitates its absorption. Without intrinsic factor, only a small percentage of vitamin B12 is absorbed. Once absorbed, relatively large amounts of vitamin B12 can be stored in the liver. The body actually reabsorbs vitamin B12 in the intestines and returns much of it to the liver, allowing for very little to be excreted from the body. However, when there are problems in the intestines, such as the microflora being imbalanced resulting in gastrointestinal inflammation, then vitamin B12 deficiencies can occur. -
Optimal Foods
Optimal Foods 1. Almonds: high in monounsaturated and polyunsaturated fats, with 20% of calories coming from protein and dietary fiber. Nutrients include potassium, magnesium, calcium, iron, zinc, vitamin E and an antioxidant flavonoid called amygdlin also known as laetrile. 2. Barley: Like oat bran it is high in beta-glucan fiber which helps to lower cholesterol. Nutrients include copper, magnesium, phosphorous and niacin. 3. Berries : The darker the berry the higher in anti-oxidants. Nutritionally they are an excellent source of flavonoids, especially anthocyanidins, vitamin C and both soluble and insoluble fiber. 4. Brussels Sprouts : Similar to broccoli, and a member of the cabbage family, it contains cancer fighting glucosinolates. Nutritionally it is an excellent source of vitamin C and K, the B vitamins, beta-carotene, potassium and dietary fiber. 5. Carrots: It contains the highest source of proviatamin A carotenes as well as vitamin K, biotin, vitamin C, B6, potassium, thiamine and fiber. 6. Dark Chocolate: It is rich in the flavonoids, similar to those found in berries and apples, that are more easily absorbed than in other foods. It also provides an amino acid called arginine that helps blood vessels to dilate hence regulating blood flow and helping to lower blood pressure. Choose high-quality semisweet dark chocolate with the highest cocoa content that appeals to your taste buds. 7. Dark leafy greens : Kale, arugula, spinach, mustard greens, chard, collards, etc: low calorie, anti-oxidant dense food with carotenes, vitamin C, folic acid, manganese, copper, vitamin E, copper, vitamin B6, potassium, calcium, iron and dietary fiber. Kale is a particularly excellent bioavailable source of calcium while spinach is not. -
Self-Administering a Vitamin B12 Injection
Self-administering a Vitamin B12 injection This is usually given as an intramuscular injection, every 2-3 months. Alternatives to an intramuscular injection are: Oral Vitamin B12 at a dose of at least 1000mcg per day. • Available as tablets or a spray. They can be bought over the counter and available at most health food stores and pharmacies. • Oral Vitamin B12 is not recommended if: - If you have a bowel condition such as inflammatory bowel disease, Coeliac disease, small bowel overgrowth, bile acid malabsorption and short bowel (you will require injections) - You require an initial loading of B12 (soon after diagnosis) It is important to monitor your symptoms if you change to oral B12. If symptoms return, then the oral/sublingual dose can be increased to 2000mcg or you may need to consider starting back on injections. https://www.hollandandbarrett.com/shop/product/betteryou-pure-energy-b12-boost-oral-spray-60099160?skuid=099160 https://www.hollandandbarrett.com/search?query=%20Vitamin%20B12%20Tablets&utm_medium=cpc&utm_source=google&isSearch=true# gclid=EAIaIQobChMIh5nLgOH26AIVxLTtCh0JIA_GEAAYASAAEgJL-fD_BwE&gclsrc=aw.ds Subcutaneous (SC) injection; this is off-licence but still effective. It is considered an easier method of administration. It is how insulin and blood thinning medication are usually self-administered. Equipment needed to self-inject - Prescribed medicine - 1 syringe (2 ml) - 2 needles (1 for drawing up the drug and 1 for administration – you can use the same size needle for both). o For an IM injection; the needle gauge should be 19-25. The needle length is 1- 1 ½ inches (up to 3 inches for larger adults) o For a SC injection; the needle gauge should be 25-27. -
Guidelines on Food Fortification with Micronutrients
GUIDELINES ON FOOD FORTIFICATION FORTIFICATION FOOD ON GUIDELINES Interest in micronutrient malnutrition has increased greatly over the last few MICRONUTRIENTS WITH years. One of the main reasons is the realization that micronutrient malnutrition contributes substantially to the global burden of disease. Furthermore, although micronutrient malnutrition is more frequent and severe in the developing world and among disadvantaged populations, it also represents a public health problem in some industrialized countries. Measures to correct micronutrient deficiencies aim at ensuring consumption of a balanced diet that is adequate in every nutrient. Unfortunately, this is far from being achieved everywhere since it requires universal access to adequate food and appropriate dietary habits. Food fortification has the dual advantage of being able to deliver nutrients to large segments of the population without requiring radical changes in food consumption patterns. Drawing on several recent high quality publications and programme experience on the subject, information on food fortification has been critically analysed and then translated into scientifically sound guidelines for application in the field. The main purpose of these guidelines is to assist countries in the design and implementation of appropriate food fortification programmes. They are intended to be a resource for governments and agencies that are currently implementing or considering food fortification, and a source of information for scientists, technologists and the food industry. The guidelines are written from a nutrition and public health perspective, to provide practical guidance on how food fortification should be implemented, monitored and evaluated. They are primarily intended for nutrition-related public health programme managers, but should also be useful to all those working to control micronutrient malnutrition, including the food industry.
