Although in each case management maybe sub-optimal and may have some risk in a survival situation it can be done and may be successful with limited medication and equipment purchase amoxil once a day bacteria 5utr. Below are some suggestions for legally obtaining medicines for use in a survival medicine situation order 250 mg amoxil antibiotic after tooth extraction. Demonstrate an understanding of what each drug is for and that you know how to safely use it discount amoxil 250 mg mastercard is taking antibiotics for acne safe. This approach depends on your relationship with your doctor purchase amoxil 250 mg on-line virus jotti, and how comfortably you are discussing these issues. Then return the meds when they have expired, this will confirm that you are not using them inappropriately. This includes antibiotics, strong narcotic analgesias, and a variety of other meds. Prescription medicines are available over the counter in many third world countries. While purchasing them certainly isn’t illegal, importation into your own country may well be. While it is unlikely that a single course of antibiotics would be a problem, extreme care should be exercised with more uncommon drugs or large amounts. Should you purchase drugs in the third (or second) world you need to be absolutely sure you are getting what you believe you are, the best way is to ensure that the medications are still sealed in the original manufactures packaging. We cannot recommend this method, but obviously for some it is the only viable option. Generally speaking most veterinary drugs come from the same batches and factories as the human version, the only difference being in the labelling. If you are going to purchase veterinary medications I strongly suggest only purchasing antibiotics or topical preparations and with the following cautions: (1) Make sure you know exactly what drug you are buying, (2) avoid preparations which contain combinations of drugs and also obscure drugs for which you can find no identical human preparation and (3) avoid drug preparations for specific animal conditions for which there is no human equivalent. A recent discussion with a number of doctors suggests that options ii and iii would be acceptable to the majority of those spoken too. In fact many were surprisingly broad in what they would be prepared to supply in those situations. However, be warned the majority of the same group considered the preparedness/survivalism philosophy to be unhealthy! Try looking in the yellow pages for medical, or emergency medical supply houses, or veterinary supplies. A number of commercial survival outfitters offer first aid and medical supplies, however, I would shop around before purchasing from these companies as their prices, in my experience, are higher than standard medical suppliers. The above approaches for obtaining medicines can also be used for obtaining medical equipment if you do have problems. The most important point is to be able to demonstrate an understanding of how to use what you are requesting. Pre-packaged Kits: Generally speaking it is considerably cheaper to purchase your own supplies and put together your own kit. The commercial kits cost 2-3 times more than the same kit would cost to put together yourself and frequently contain items which are of limited value. Storage and Rotation of Medications Medications can be one of the more expensive items in your storage inventory, and there can be a reluctance to rotate them due to this cost issue, and also due to difficulties in obtaining new stock. It is our experience that these are usually very easy to follow, without the confusing codes sometimes found on food products, e. We cannot endorse using medications which have expired, but having said that, the majority of medications are safe for at least 12 months following their expiration date. As with food the main problem with expired medicines is not that they become dangerous but that they lose potency over time and the manufacturer will no longer guarantee the dose/response effects of the drug. The important exception to this rule was always said to be the tetracycline group of antibiotics which could become toxic with time. However, it is thought that the toxicity with degrading tetracycline was due to citric acid which was part of the tablet composition. Citric acid is no longer used in the production of tetracycline, therefore, the dangers of toxicity with degradation of tetracycline is no longer a problem. Aspirin and Epinephrine do break down over time to toxic metabolites and extreme care should be taken using these medications beyond their expiry dates. It depends upon what you are preparing for and the number of people you will be looking after. In order get a rough idea of what you should stock – think of your worse case scenario and at least double or triple the amounts you calculate. Items which never go as far as you think they will include – gauze, tape, antibiotics, and sutures. If you have ever been hospitalised or had a close relative in hospital for even a relatively minor problem take a look at the billing account for medical supplies and drugs to get an idea how much can be consumed with even a relatively small problem. It is simple mathematics; drugs which you need to take more than once or twice a day disappear extremely fast – penicillin 4 times a day for 10 days on a couple of occasions quickly erodes your “large stock” of 100 tablets! Specific Medical Kits Everyone has an idea of what his or her perfect kit is and what he or she thinks is vital - so there is no perfect kit-packing list. What is perfect for one person’s situation and knowledge may not be perfect for yours. In this section we have looked at a basic first aid kit, a more broad-spectrum basic medical kit, and an advanced medical kit able to cope with most medical problems. These are not the perfect kits or the ideal packing list – but they give you some idea of what we consider are needed to provide varying levels of care. There is also frequent confusion over which surgical instruments to buy, how many of each, and what some actually do so we have gone into more detail looking at some possible surgical and dental kits, and what level of care can be delivered with each. Unfortunately most medications require rotation with 1- 5 year shelf lives, making this a costly exercise, as they are not like food you can rotate into the kitchen 3) Always store a supply of any medicines you take regularly. However, it is vital to remember the blood pressure pills, thyroid hormones, allergy pills, contraceptive pills, asthma inhalers, or what ever you take regularly. Most doctors will issue additional prescriptions for regular medication to allow an extra supply at a holiday home or to leave a supply at work. The main problem likely to arise is covering the cost of the extra medication which may be expensive and not covered by insurance. If you have previously had severe allergic reactions consider having a supply of Epi-pens Figure 4. If you have a chronic medical problem such as asthma, you must ensure you have an adequate supply of your medication. There is large selection of medical bags on the market – military and civilian styles, rigid and soft construction. We have selected 3-4 bags in each size range – personal use, first responder, and large multi-compartment bags. If in a fixed location consider buying a rolling mechanics tool chest and using it as a “crash cart”. Personal size: • Battle pack (Chinook Medical gear) • Modular Medical Pouch (Tactical Tailor) • Compact individual medical pouch (S. When you have selected the bags that suit you, one approach to organising your medical supplies is: Personal bag: Carry this with you at all time. It contains basic first aid gear or in a tactical situation the equipment to deal with injuries from a gunshot wound or explosion. The management of an airway has a number of steps: • Basic airway manoeuvres – head tilt, chin lift, jaw thrust. A plastic tube from the mouth into the trachea through which a patient can be ventilated. In addition once you have managed the airway you need to ventilate the patient either with mouth-to-mouth/mask or using a mask - self inflating bag combination (e. The reason for discussing this is that you need to decide how much airway equipment to stock. Our view is that there is relatively little need to stock anything more than simple airway devices such as oral or nasal airways unless you are planning (and have the skills) to give an anaesthetic for the simple reason that anyone one who requires advanced airway management is likely to be unsalvageable in an austere situation. If simple devices are not sufficient then they are likely to die regardless and introducing relatively complicated airway devices will not help. From left – Surgical airway, Laryngoscope and blades, endotracheal tube, McGill forceps, self inflating bag and mask, oral and nasal airways. With relatively simple equipment and supplies you can stop bleeding, splint a fracture, and provide basic patient assessment. The following are the key components of any kit albeit for a work, sport, or survival orientated first aid kit: Dressings – Small gauze squares/large squares/Combined dressings/battle dressings/ non-adhesive dressings. Exactly what you need is to a large degree personal preference – but whatever you buy you need small and large sizes, and they need to be absorbent. Roller/Crepe Bandages – These go by various names (Crepe, Kerlix) – but we are talking about is some form of elasticised roller bandage. These are required to hold dressings in place, apply pressure to bleeding wounds, to help splint fractures, and to strap and support joint sprains. They come in a variety of sizes from 3 cm to 15 cm (1- 4”) and you should stock a variety of sizes Triangular bandages – These are triangular shapes of material which can be used for making slings, and splinting fractures, and sprains. Often when combined with basic airway opening manoeuvres these are sufficient to maintain the airway of an unconscious person. Sterile normal saline (salt water) or water – You don’t need expensive antiseptic solutions for cleaning wounds. Sterile saline or water (and to be honest – even tap water is fine for most wound cleaning) is all that’s required to irrigate or clean contaminated wounds.
Better understanding of genetics promises a future of precise buy amoxil 500 mg lowest price antibiotic x 14547a, customized medical treatments buy discount amoxil 500mg online bacteria 2. Prognosis Diagnosing ailments more precisely will lead to more reliable predictions about the course of a disease buy amoxil 500mg fast delivery antibiotics renal failure. For example discount amoxil 250mg without a prescription antibiotics for inflammatory acne, a genetic work- up can inform a patient with high cholesterol levels how damaging that condition is likely to be. And doctors treating prostate cancer will be able to predict how aggressive a tumor will be. For many diseases, such genetic information will help patients and doctors weigh the risks and benefits of different treatments. In many cases, this advance warning can be a cue to start a vigilant screening program, to take preventive medicines, or to make diet or lifestyle changes that might prevent the disease altogether. For example, those at risk for colon cancer could undergo frequent colonoscopies; those with hereditary hemochromatosis, a common disorder of iron metabolism, could donate blood periodically to remove excess iron and prevent damage to the body. Some women at risk for breast cancer could benefit from tamoxifen; a young person at risk for developing lung cancer may become particularly motivated to quit smoking; those with familial hypercholesterolemia could begin treatment to lower their cholesterol levels and prevent heart attacks and strokes. Unfortunately, our ability to predict a disease sometimes precedes our ability to prevent or treat it. For example, a genetic test has been avail- able for Huntington disease for years, but no treatment is available yet. Testing 10 Gene-base Genetic Medicine 11 Newborn screening A particular form of predictive testing, newborn screening can sometimes help a great deal. In the past, children with the condition became severely mentally retarded, but the screening program identifies children with the enzyme deficiency, allowing them to grow normally on a diet that strictly avoids phenylalanine. Carrier screening For some genetic conditions, people who will never be ill themselves can pass a disease to their children. Some couples choose to be tested for this risk before they marry, especially in commu- nities where a feared childhood disease is particularly common. For example, carrier testing for Tay-Sachs disease, which kills young children and is particularly common in some Jewish and Canadian populations, has been available and widely used for years. Gene therapy Replacing a misspelled gene with a functional gene has long been an appealing idea. Small groups of patients have undergone gene therapy in clinical trials for more than a decade, but this remains an experimental treatment. Gene-based therapy Great medical benefit likely will derive from drug design that’s guided by an understanding of how genes work and what exactly happens at the molecular level to cause disease. For example, the causes of adult-onset diabetes and the resulting complications remain difficult to decipher and, so, to treat. But researchers are opti- mistic that a more precise understanding of the underlying causes will lead to better therapies. In many cases, instead of trying to replace a gene, it will be more effective and simpler to replace the protein the gene would give rise to. Alternatively, it may be possible to administer a small molecule that interacts with the protein—as many drugs do—and changes its behavior. One of the first examples of such a rationally-designed drug targets the genetic flaw that causes chronic myelogenous leukemia, a form of leukemia that mostly affects adults. An unusual joining of chromosomes 9 and 22 produces an abnormal protein that spurs the uncontrolled growth of white blood cells. Scientists have designed a drug that specifically attaches to the abnormal protein and blocks its activity. In preliminary tests, blood counts returned to normal in all patients treated with the drug. And, compared with other forms of cancer treatment, the patients experienced very mild side effects. Instead of having to rely on chance and screening thousands of mole- cules to find an effective drug, which is how most drugs we use today were found, scientists will begin the process of drug discovery with a clearer notion of what they’re looking for. And because rationally designed drugs are more likely to act very specifically, they will be less likely to have damaging side effects. Genomics will hasten the advance of molecular biology into the practice of medicine. As the molecular foundations of diseases become clearer, we may be able to prevent them in many cases and in other cases, design accurate, individualized treatments for them. New drugs, derived from a detailed molecular understanding of common illnesses like diabetes and high blood pressure, will target molecules logically. Decades from now, many potential diseases may be cured at the molecular level before they arise. But access to genome sequence will increasingly shape the practice of health care over the coming decades, as well as shed light on many of the mysteries of biology.

They reflect law enforcement decisions to concentrate resources in low income minority neighborhoods. They also reflect deep-rooted racialized concerns, beliefs, and attitudes that shape the nation’s understanding of the “drug problem” and skew the policies chosen to respond to it. International human rights law, in contrast, call for the elimination of all racial discrimination, even if unaccompanied by racist intent. Keywords: race, drugs, discrimination, arrests, incarceration, structural racism Millions of people have been arrested and incarcerated on drug charges in the past 30 years as part of America’s “war on drugs. But perhaps the single most powerful indictment is that war has, been waged overwhelmingly against black Americans who have been disproportionately arrested and incarcerated on drug charges as a result. Racial disparities generated or deepened by public policies should always be cause for concern. The choice of arrest and imprisonment as the primary antidrug strategy has thwarted efforts to improve the opportunities and living standards of black Americans, deepened the disadvantages of poverty and social marginalization, and threatened hard-fought civil rights progress. In addition to losing their liberty, prisoners endure the rigors of living in harsh, tense, overcrowded, barren, and often dangerous facilities. Maintaining contact with their families is extremely difficult; family stability and well- being are jeopardized when a breadwinner or parent is taken away. The consequences of a criminal conviction last far longer than the time spent in jail or prison. People with criminal records experience what can be a lifetime of stigma and legal discrimination in employment, housing, education, public benefits, jury service, and the right to vote. Families and communities are injured by these policies as well (Mauer and Chesney-Lind 2003; Western 2006; Clear 2007). A number of conclusions leap from readily available data: • Black Americans are much more likely than white Americans to be arrested and incarcerated for drug crimes. In short, racial disparities in arrest and imprisonment for drug crimes cannot be explained by racial patterns of drug crime. There are operational reasons for the disparities; most importantly, drug law enforcement activities are concentrated in inner city areas with high minority populations. But law enforcement’s strategic choices in turn reflect the longstanding influence of race on how the United States has defined the drug problem. Section I of this article discusses and documents the role of race in the development of drug control efforts in the United States and presents statistics revealing that black Americans have been and continue to be arrested, convicted, and incarcerated on drug charges at rates far higher than those for whites. Blacks are arrested on drug charges at three times the rate for whites and are sent to state prison1 on drug charges at 10 times the rate for whites. The net result is that more black than white Americans are doing time for drug offenses in a country in which only 12. The arrest and incarceration disparities cannot be explained by racial differences in drug offending because there are far more white than black drug offenders. Overall, slightly larger percentages of black people have used illegal drugs in the past year or month, although a higher percentage of white people have used drugs in their lifetime. In absolute numbers, however, the numbers of white users of illicit drugs—even crack—dwarf black numbers because there are five to six times as many white as black Americans. Evidence of racial patterns in drug trafficking is less strong than concerning use, but what there is suggests that black drug-selling rates are little or no higher than white rates and, accordingly, that there are many more white than black sellers. Arrest rates are much higher for blacks than whites largely because police focus drug law enforcement on places, principally inner-cities, with high minority populations and target their resources where drug arrests are easiest —on the streets, rather than in private home or office buildings. Imprisonment disparities are even worse than arrest disparities with blacks more likely to be sentenced to prison for drug offenses and to receive longer sentences than whites. To some extent, longer sentences for black drug offenders reflect federal and some state drug laws that mandate especially severe penalties for crack offenses for which blacks are disproportionately arrested. They also reflect the fact that black drug arrestees are more likely to have prior convictions that lead to sentence enhancements. Racial disparities in drug law enforcement result from the combined effects of many social, geographic, and political factors operating at federal, state, and local levels, but they also reflect the influence of racialized considerations and concerns in the decisions of legislators, police, prosecutors, and judges. Overt racial prejudice may not be at work, but extensive research and analysis over the past few decades leave little doubt that antidrug efforts are rooted in and reflect the unconscious racial bias of whites against blacks as well as race relation dynamics that benefit whites to the detriment of blacks. The United States has a human rights obligation to end such disparities, but it cannot do so until it acknowledges how deeply racial discrimination has permeated its antidrug efforts. Race and Drug Laws Crimes are social constructs, reflecting historically evolving and culturally specific sets of moral views and social and political imperatives. The wrongfulness of certain behavior, for example, murder, is intuitively understood by most people to warrant criminalization. Whether and why the possession and sale of certain substances used for recreation should be criminalized is far less easy to understand (Husak 1992, 2008). It is also a story about race and ethnicity: group antagonisms, fears, and tensions have played powerful roles in shaping U. Criminalization of drugs was historically one way that dominant, white social groups sought to maintain control over racial and ethnic minorities who troubled, angered, or scared them (Musto 1999).
All of the above five methods are based on measuring a change in the particular endpoint in response to graded levels of the test amino acid buy discount amoxil line bacteria gif. A key observation regarding nitrogen balance as an endpoint is that there is a curvilinear relationship between nitrogen balance and test amino acid intake buy cheap amoxil line bacteria science projects, so that nitrogen retention (nitrogen balance) becomes less efficient as zero balance is approached (Figure 10-7) (Rand and Young order amoxil 250 mg amex virus 58 symptoms, 1999) order 500 mg amoxil fast delivery antibiotic lecture. Furthermore, the earlier work did not include miscella- neous losses in their nitrogen balances. Finally, most studies did not attempt to consider the effect of between-individual variance. Only two studies were found in which several individuals were studied at four or more different levels of intake of the test amino acid (Jones et al. They also examined the effect of adding either 5 or 8 mg/kg/d of miscellaneous nitrogen losses. Whereas Jones and coworkers (1956) had concluded, based on their data, that the lysine requirement was 8 mg/kg/d, the reanalysis by Rand and Young (1999) came to the conclusion that the lysine requirement was in the range of 17 to 36 mg/kg/d, and that the data strongly support a requirement of about 30 mg/kg/d. As shown in Table 10-22, 24-hour amino acid balance studies have been completed for four amino acids: leucine (El-Khoury et al. The 24-hour balance model is regarded as being the best from a theoretical point of view, especially when performed with the indicator approach. However, from a practical point of view, the 24-hour amino acid balance studies are very labor intensive with the result that only three or four levels of intake of the test amino acid have been studied for each of leucine, lysine, phenylalanine + tyrosine, and threonine. Nonlinear regression was used on two sets of nitrogen balance data as shown by Rand and Young (1999). The first was for lysine in which the original data were in women, each of whom were studied at two to five levels (Jones et al. This data set was reanalyzed using nonlinear regression, including the addition of 5 or 8 mg of nitrogen/kg/d as miscellaneous losses (Rand and Young, 1999), and these reanalyzed data are included in Table 10-22. Using a similar approach, the data of Reynolds and coworkers (1958) for methionine + cysteine were reanalyzed, and these data are included in Table 10-22. The result is consistent with the data of Zezulka and Calloway (1976a, 1976b), who studied the effect on nitrogen balance of three levels of methionine added to soy protein at a constant and adequate level of total nitrogen. Since there are no direct estimates of the isoleucine requirement, it is estimated from the leucine and valine estimates. The isoleucine requirement was therefore calculated by multiplying the isoleucine requirement calculated from the protein requirement (Table 10-20) by 1. This approach is weakest with the phenylalanine + tyrosine requirements where there is a large range—from 15. Given the very few studies available, separate requirements could not be determined for women versus men, or for young and older adults. However, an approximate standard devia- tion was calculated as half of the distance from the 16th to the 84th per- centile of the protein requirement distribution as estimated from the log normal distribution of requirements. The quality of a source of protein (or more specifically the source of nitrogen, since dietary protein is generally measured analytically in terms of nitrogen) is an expression of its ability to provide the nitrogen and amino acid requirements for growth, mainte- nance, and repair. In practice, protein quality is principally determined by two factors: digestibility and the amino acid composition of the protein in question. In food as opposed to relatively pure protein, the contribution of all of the indispensable amino acids to the total nitrogen content of the food has to be considered in assessing the overall protein quality of the diet. Digestibility Nitrogen is excreted in the feces in amounts that usually vary between 10 and 25 percent of the nitrogen intake. The unabsorbed part represents mainly proteins that, by reason of their physical characteristics or chemical composition, are resistant to breakdown by the proteolytic digestive enzymes. There is probably a variable contribution of nitrogen contained in other non- absorbable components, such as amino sugars and other nitrogen- containing materials found in cell walls. On the other hand, the secretions consist of specific proteins, such as mucins, which represent a loss that is of nutritional importance. How- ever, both the nonabsorbed and secreted components that make up nitro- gen loss are difficult to quantify with any confidence, except in terms of total nitrogen, because of the overwhelming modifying effect of the intes- tinal microflora. This value is then subtracted from the total nitrogen intake (N ) and expressed as a propor-I tion of the nitrogen intake. Fecal nitrogen from a protein-free diet is a measure of the amount of nitrogen from intestinal secretions, on the assumption (probably incor- rect) that this component does not vary with different diets (de Lange et al. The values thus calculated are called “true” digestibility and represent the proportion of the dietary nitrogen that is absorbed. This portion can generally be assumed to be available to the host for meeting the needs for maintenance and growth. It must be noted that a number of recent studies with isotopically labeled proteins suggest that true digestibility exceeds 90 percent for many common foods such as milk, cereals, and soy and other legumes (Darragh and Hodgkinson, 2000, de Vrese et al. It should also be noted that, at present, calculation of the availability (or digestibility) of amino acids from food protein sources is based on the digestibility of total nitro- gen as contrasted to that for the individual amino acid. However, there can be quite large differences between the digestibility coefficients for total nitrogen and the individual amino acid. These and other related aspects of protein quality have been reviewed elsewhere (Darragh and Hodgkinson, 2000; Schaafsma, 2000). Nitrogen Versus Amino Acids Absorbed nitrogen is mainly in the form of amino acids, but a propor- tion is in other compounds such as nucleic acids, creatine, amino sugars, ammonia, and urea. The quantitative extent to which these contribute to nitrogen retention and homeostasis is not known. However, the major requirement for total nitrogen or protein is for the specific indispensable amino acids (and/or conditionally indispensable amino acids) and an additional source of α-amino nitrogen. At appropriate intakes these main- tain protein homeostasis and adequate synthesis of those physiologically important compounds for which amino acids are the obligatory precursors (Table 10-5). For example, when protein intake is calculated by summing the weight of amino acids as analyzed in a food (less the water of hydrolysis), the protein/nitrogen ratio is 5. Thus when converting the amount of nitrogen present in a specific foodstuff to total protein, this factor becomes impor- tant to use. These differences in the protein-to-nitrogen ratio of food proteins are not of specific importance in reference to the development of the recom- mendations for protein requirements given herein. This is because these recommendations have been based initially on nitrogen balance determi- nations, which in turn were based on analytical measurements of nitrogen intake (from different test proteins or mixtures of proteins). The nitrogen intake values were then converted to protein intakes using the conven- tional 6. In this case, protein intakes and the relation between the amino acid concentrations in the protein should all be referred back to a nitrogen base. For this reason, amino acid requirement patterns delineated below are given in reference to both conventional protein (nitrogen × 6. Amino Acids Content of Proteins The second and generally more important factor that influences the nutritional value of a protein source is the relative content and metabolic availability of the individual indispensable amino acids. If the content of a single indispensable amino acid in the diet is less than the individual’s requirement, then it will limit the utilization of other amino acids and thus prevent normal rates of protein synthesis even when the total nitrogen intake level is adequate. Thus, the “limiting amino acid” will determine the nutritional value of the total nitrogen or protein in the diet. This has been illustrated in experiments comparing the relative ability of different protein sources to maintain nitrogen balance. For example, studies have shown, depending on its source and preparation, that more soy protein might be needed to maintain nitrogen balance when compared to egg- white protein, and that the difference may be eliminated by the addition of methionine to the soy diet. This indicates that sulfur amino acids can be limiting in soy (Zezulka and Calloway, 1976a, 1976b). The concept of the limiting amino acid has led to the practice of amino acid (or chemical) scoring, whereby the indispensable amino acid composition of the specific protein source is compared with that of a refer- ence amino acid composition profile. Table 10-23 shows the com- position of various food protein sources expressed as mg of amino acid per g of protein (nitrogen × 6. The composition of amino acids of egg and milk proteins is similar with the exception of the sulfur amino acids methionine and cysteine. However, wheat and beans have lower propor- tions of indispensable amino acids, especially of lysine and sulfur amino acids, respectively. Amino Acid Scoring and Protein Quality In recent years, the amino acid requirement values for humans have been used to develop reference amino acid patterns for purposes of evalu- ating the quality of food proteins or their capacity to efficiently meet both the nitrogen and indispensable amino acid requirements of the individual. Based on the estimated average requirements for the individual indispens- able amino acids presented earlier (Tables 10-20 and 10-21) and for total protein (nitrogen × 6. These are given in Table 10-24 together with the amino acid requirement pattern used for breast-fed infants. It should be noted that this latter pattern is that for human milk and so it is derived quite differently compared to that for the other age groups. There are three important points that need to be highlighted about the proposed amino acid scoring patterns. First, there are relatively small differences between the amino acid requirement and thus scoring patterns for children and adults, therefore use amino acid requirement pattern for 1 to 3 years of age is recommended as the reference pattern for purposes of assessment and planning of the protein component of diets. Second, the requirement pattern proposed here for adults is funda- mentally different from a number of previously recommended require- ment patterns (Table 10-25). The other requirement patterns shown in Table 10-25 for adults were pub- lished in two recent reviews (Millward, 1999; Young and Borgonha, 2000). Thus, the reference amino acid scoring patterns shown in Table 10-24 are designed for use in the evaluation of dietary protein quality. However, two important statistical considerations need to be raised here: first, the extent to which there is a correlation between nitrogen (protein) and the requirement for a specific indispensable amino acid; second, the impact of the variance for both protein and amino acid requirements on the derived amino acid reference pattern. The extent to which the requirements for specific indis- pensable amino acids and total protein are correlated is not known. In this report it is assumed that the variance in requirement for each indispens- able amino acid is the same as that for the adult protein requirement. This analysis illustrates one of the uncertainties faced in establishing a reference or scoring pattern and judging the nutritional value of a protein source for an individual.
By being prepared and planning for this scenario purchase amoxil online from canada bacteria on cell phones, it can be ensured that the attention of the media works to help the situation purchase amoxil with visa bacteria chlamydia trachomatis. The communications plan should cover buy generic amoxil line antibiotics for extreme acne, for example order 500 mg amoxil with amex antibiotic guideline, whether: a) nominated people within an organisation are a spokesperson and/or field enquiries, or b) enquiries are passed on to other organisations with greater relevant communications resources and experience. When dealing with the media over disease risks, there are a number of guidelines which may be helpful and should be borne in mind. Write the plan in ‘peacetime’, before a disease problem, when it is easy to take time and plan calmly. Clearly assign roles and responsibilities, including a single organisational contact point for media inquiries and spokespeople. In peacetime, train a small number of key spokespeople (exercises can be very useful). Foster good relationships with the media in ‘peacetime’ by briefing them on wetland issues. If dealing with the media does not bring benefits, then do not be afraid to say no to journalists - you will not offend them or ruin your relationship, they are used to hearing no, they respect it and often expect it. It will help to determine scenarios when you will proactively use the media and when you will only react to enquiries. If you are responding to an inquiry, ask beforehand what is the nature and angle of the media story so you have opportunity to prepare and do some background research. Ensure that what you say is evidence-based (qualify the certainty of your statements if necessary), avoid speculation and stick to your area of expertise. It is key is to get people to stick to the plan and not panic – this is sometimes hard!

It is very easy to stray into and comment on other topics to reinforce your point. Taking the scientific approach of waiting for evidence before commenting on likely routes of infection may be seen as ‘sitting on the fence’, especially when media will want immediate answers. This includes personnel managing a site, assessing the risk of an outbreak, reducing the risk of disease emergence, involved in the diagnosis and surveillance of a disease, and controlling an outbreak. Training is particularly important for front-line personnel, who are likely to come into contact with an incursion or outbreak of disease first, such as, wetland managers and members of disease diagnostic teams. All appropriate stakeholders should be thoroughly trained in their roles and responsibilities in a disease emergency. More intense and specialised training is needed for personnel/professionals holding key positions, such as members of specialist diagnostic and surveillance teams, forecasting experts and animal and human health professionals. Moreover, training programmes should be comprehensive and regular, to accommodate the possibility that a disease may occur in any part of a country, and to allow for staff turnover. Training must extend to staff in remote areas, as well as to selected officials, such as local authorities. Back up staff for each position should also be trained, in the eventuality of absent front-line staff. It will not always be possible, or practical, to train all personnel to a high level of expertise in the diseases themselves. Knowledge of basic clinical, pathological and epidemiological features of diseases known to be important, or potentially important, to a site, together with an understanding of actions to be taken when the presence of disease is suspected, may suffice in many circumstances. Importantly, the principles and practicalities of investigating a disease outbreak with an open mind should be the subject of training [►Section 3. The following training possibilities may be selected, as appropriate: National emergency disease training workshops: coordinated workshops should form the focus of training and should target those involved in each stage of managing an outbreak. These workshops should be organised by trained personnel and ideally include representatives from, for example, neighbouring counties or regions, or those countries or regions with experience of dealing with the specific disease in question. Exchange of personnel: key staff should be sent to other disease control centres which are proficient in dealing with the relevant disease, particularly those in the process of controlling an outbreak, to gain first-hand experience of steps taken to manage an outbreak. Other opportunities for staff to gain knowledge and understanding of managing outbreaks, such as attending workshops, should also be utilised. Linkages with international disease control centres and reference laboratories should be fostered to share knowledge about, and ‘lessons learned’ from, managing outbreaks. Training and field manuals may be useful for reference but ideally, should not be solely relied upon for training. Realistic disease outbreak scenarios should be created, using real data where possible. A scenario may cover several phases of an outbreak, with a range of possible outcomes, but should not be overly complicated or long. Simulation exercises can be desk-based, involve mock activities or combine both approaches. There should be a review after completion of each simulation exercise to identify further training needs and any areas of the contingency plan in need of modification. A full-scale disease outbreak simulation exercise should be attempted after individual components of the disease control response have been tested. Care must be taken to ensure that the simulation exercises are not confused with actual outbreaks in the minds of the media and the public (e. Desk top or practical simulation exercises to test contingency plans are highly valuable, particularly when bringing together a range of stakeholders including disease control agencies. The aim of the course was to develop skills amongst ornithological practitioners and infrastructure to allow long term wild bird avian influenza surveillance to be established in this region of Nigeria and provide skilled personnel for surveillance in the countries of the other African participants. The course trained 31 participants from five mainly Chad Basin countries (Nigeria (23), Niger (2), Chad (2) and also Sudan (2) and Kenya (2)). The course proved to be very successful and was deemed by participants to have fully achieved its objectives and their personal objectives also. A variety of capture techniques were taught with the main focus on the advanced technique of cannon netting. Cannon netting has the potential to allow the capture of large numbers of ducks (the main target for avian influenza surveillance) and is of particular use in areas where other trapping methods cannot be used. Duplicate sets of avian influenza cloacal and oropharyngeal swab samples were taken from trapped (1) waterbirds, one set for in-country analysis at the National Veterinary Research Institute, Vom, Nigeria, and one set for the New FluBird partner University of Kalmar, Sweden. Cannon netting is a technical, complex and potentially hazardous trapping technique and successful cannon netters and cannon netting teams require certain key attributes. Many of the already experienced participants proved themselves to be very technically adept and capable bird trappers and with a little extra training within existing experienced cannon netting teams should be competent at being part of a regional cannon netting team capable of both national and international wild bird surveillance programmes.
