Migraine alone is the seventh highest specific cause of disability globally and the leading cause worldwide of neurological disability, according to the World Health Organization 2010 Burden of Disease Study. It also provides education and training to physicians, health professionals and the public about headache and encourages scientific research worldwide about the causes and treatment of headache and related problems. This has led many clinicians to utilize ultrasound to determine if splenic enlargement is present. However, because individual splenic diameters vary greatly, comparing splenic size to population norms is not a valid method to assess splenic enlargement. The cause of female athlete triad is an imbalance between energy intake and energy expenditure that leads to menstrual dysfunction (abnormal or loss of periods) and low bone mineral density. Treatment includes increasing caloric intake and/or decreasing energy expenditure (exercise) to restore normal menses, which can take up to 12 months or longer. We recommend a multi-disciplinary approach to treatment that includes a physician, dietitian, mental health professional (when appropriate) and support from coaches, family members and friends. Treatment should focus on a guided exercise program to correct lumbopelvic and lower limb strength and flexibility imbalances. Degenerative meniscal tears may respond to non-operative treatments such as exercise to improve muscle strength, endurance and flexibility. Other treatment options include mild analgesics, anti-inflammatory medication, activity modification or corticosteroid injection. If mechanical symptoms such as locking, painful clicking or recurrent swelling are present, or if pain relief is not obtained after a trial of non-operative treatment, arthroscopy may be warranted. If significant osteoarthritis is also present, other surgical options should be considered. The goal was to identify common topics in the practice of sports medicine that, supported by a review of the literature, would lead to significant health benefits and a reduction of common procedures that can be unnecessary or cause harm. For each item, evidence was reviewed from peer-reviewed literature and several sports medicine consensus statements.

By nature of their training and experience, sports medicine physicians are ideally suited to provide comprehensive medical care for athletes, sports teams or active individuals who are simply looking to maintain a healthy lifestyle. Research shows that using purposeful activity (occupation) in interventions is an intrinsic motivator for patients. Such activities can increase attention, endurance, motor performance, pain tolerance, and engagement, resulting in better patient outcomes. Conversely, non-purposeful activities do not stimulate interest or motivation, resulting in reduced patient participation and suboptimal outcomes. Many children and youth are affected by challenges in processing and integrating sensations that negatively affect their ability to participate in meaningful and valued occupations. Processing and integrating sensations are complex and result in individualized patterns of dysfunction that must be addressed in personalized ways. Interventions that do not target the documented patterns of dysfunction can produce ineffective or negative results. Therefore, it is imperative to assess and document specific sensory difficulties before providing sensory-based interventions such as Ayres Sensory Integration, weighted vests, listening programs, or sensory diets. Use of an overhead pulley for individuals with a hemiplegic shoulder resulting from a stroke or other clinical condition is considered too aggressive and should be avoided, as it presents the highest risk of the patient developing shoulder pain. To improve occupational performance, cognitive-based interventions should be embedded in an occupation relevant to the patient. Examples of cognitive-based interventions include awareness approaches, strategy training, task training, environmental modifications, and assistive technology. The use of cognitive-based interventions not based on occupational performance will result in suboptimal patient outcomes. Phase I was completed with an online member survey that resulted in 328 responses. Following the elimination of duplicate responses and items outside the scope of occupational therapy practice, the list was narrowed down to 62 items. This survey resulted in 4,860 responses that were analyzed, resulting in the final 5 items. A comparison of performance in added-purpose occupations and rote exercise for dynamic standing balance in persons with hemiplegia.

Within a week of no training diabetes test negative generic glipizide 10 mg fast delivery, swimmers lose on average 50% of the respiratory capacity of their muscles (Reilly diabetes mellitus type 1 definition buy glipizide with american express, 1990b) diabetes diet cookbook discount glipizide 10mg overnight delivery, but regaining this capacity takes considerably longer during retraining. In sum, most anatomical characteristics, unlike height, are remarkably adaptable to intense physical activity extended over long periods of time. Detailed biochemical mechanisms mediating the transformation of the phenotype of muscle fibers in response to intense physical activity (Booth, 1989) and general mechanisms for influence of environmental factors on developmental outcomes are now being proposed and evaluated (Gottlieb, 1992). Many extreme physical characteristics in elite athletes are the result of the same adaptive processes that determine similar characteristics in the normal population, and the extreme differences in these attributes correspond to the equally extreme differences in the amount and intensity of practice between these two groups. A reasonable objection to the generalizability of the effects of training for all adults can be made on the basis of the large dropout rate for adults from exercise programs (Martin & Dubbert, 1985). It is apparently not possible to motivate all people to engage in regular exercise. Research on the effects of extended exercise in animals has demonstrated that intensive exercise results in conversion of muscle fibers (Pette, 1984) and enlargement of hearts (Harpur, 1980). The primary method for motivating animals to exercise vigorously is punishment, for example, running on a treadmill with a slope to avoid a bar giving electric shock or swimming with or without additional weights. However, similar but less pronounced effects have been attained from animals that voluntarily run in a wheel compared with those in a sedentary condition (Harpur, 1980). Recent research has shown activity-specific physiological changes resulting from extended practice also in the central 395 nervous system. After difficult acrobatic training an increased number of synapses in the cerebellar cortex were found for rats, but not for rats engaged in extensive physical exercise, which instead exhibited a greater density of blood vessels in the same area (Black, Isaacs, Anderson, Alcantara, & Greenough, 1990). Replications of the adaptive changes with animals under controlled conditions are likely to be the best obtainable evidence on generalizability given the problems of motivating random samples of humans. Early Demonstrated Abilities Assumed to Reflect Innate Talent In the introduction we mentioned several abilities demonstrated by children and idiot savants that have been thought to reflect innate talents and predispositions. We also briefly discuss other abilities of idiot savants and some of the anatomical characteristics of ballet dancers and swimmers. Perfect pitch (or absolute pitch), the ability to identify isolated musical tones, is considered a sign of musical talent. Often future elite musicians and musical savants exhibit perfect pitch at an early age. Qualitatively different processes mediate the performance of individuals with perfect pitch and that of musicians who lack it. Individuals with absolute pitch tend to confuse tones with the same location in different subscales but not tones having the smallest difference in fundamental frequencies. For example, an untrained subject might confuse C with B, whereas a subject with perfect pitch would confuse C in one octave with C in a different octave (Ward & Burns, 1982). Individuals with "perfect pitch" differ in their ability to judge pitches and perform best when judging pitches generated with the instrument they play. As the tests of ability to recognize pitch get harder, as they do when artificially generated sinus tones are used, for example, fewer and fewer subjects pass the tests (Oakes, 1955). Brady (1970) demonstrated that he was able to acquire perfect pitch by an intriguing training procedure, which involved learning to identify a single tone. Brady reported that once developed, the identification task required little effort and that he did not have to practice purposefully to maintain the skill. No decrement in performance was reported after 6 months, and only a slight decrement was reported after 13 years (Costall, 1985). Finally, recent research (Cohen & Baird, 1990) provides evidence that normal children, especially before age 5, more easily recognize notes individually (absolute pitch) before they perceive notes as part of larger musical structures (relative pitch). These findings suggest that subjects with absolute pitch acquire the necessary skill as children and then simply maintain it for the rest of their lives (Miyazaki, 1990). Johnson & Newport, 1989), and with Japanese subjects learning to make the difficult distinction between [r] and  in English (Yamada, 1991). The importance of early practice and experience for adult ability is similarly found in swimming and ballet. Ballet training must start before dancers reach age 11 to gain the necessary 396 K. In summary, exceptional abilities observed in children and idiot savants are consistent with all the characteristics of acquired skills. Most of them can be easily acquired by adults through known training methods, although some of them may be more easily acquired during childhood. The motivational factors that lead children and idiot savants to focus their time and energy on activities that improve performance are still poorly understood. General Difficulties of Predicting Ultimate Performance From Initial Performance: Qualitative Differences Acquired Through Extended Practice In the introduction we briefly reviewed the difficulties of predicting the level of expert performance individuals attain after extended practice. Bound up with the notion of innate talents, which are revealed during early performance, is the notion that the same fixed components determine both early performance and the final level of performance and thus enable observers to identify and select future exceptional performers as well as to predict their final achievement after practice. In this section we briefly review the literature on individual differences in performance as a function of practice in studies of skill acquisition. We then review some findings on the nature of individual differences in expert performance. Extensive research on skill acquisition with college students and more representative samples, such as military recruits, shows that performance on a wide range of tasks improves monotonically as a function of many hours of practice. Anderson, 1982; Fitts, 1964; Fitts & Posner, 1967) propose that initial performance is mediated by sequential processes, which with additional practice are transformed into a single direct (automatic) retrieval of the correct response from memory. This radical change in processing makes it difficult to identify any locus for individual differences in innate talent that could influence initial superiority as well as superior final performance. The most successful attempts to relate individual differences in ability to individual differences in performance have dealt with short-term skill acquisition. Evidence from these studies suggests that performance during the initial, middle, and final phase of skill acquisition is correlated with different types of abilities in each phase (Ackerman, 1988), initial performance being correlated with general cognitive abilities and final performance with perceptual-motor abilities. With several hours of practice, cognitive differences are essentially eliminated, giving way to the more "basic" differences in components associated with perception and motor production. Because, however, the perceptual and motor systems show great adaptability in response to extended practice (a phenomenon discussed earlier in this article), it may be inappropriate to generalize the findings from relatively simple tasks involving 2-20 h of practice to expert performance acquired during a 10-year period of intense preparation. Two general findings concerning individual differences in high levels of performance imply that expert performance and initial performance do not have a common basis. Stress induced during extensive training at young ages appears necessary for dancers to gain the necessary "turn out" in the different positions of demi-plie at adult ages (DiTullio et al. Dancers apparently acquire flexibility through early training as shown by a longitudinal study (Klemp & Charlton, 1989). In a large group of club swimmers (aged 8-17) the only physical measures discriminating this group from a matched control group of other types of athletes were ankle and shoulder flexibility (Poppleton & Salmoni, 1991). Consistent with the hypothesis that increased flexibility is acquired through extended swimming, it is common that elite swimmers have weak ankles, which are particularly susceptible to injury (Chambliss, 1988). Certain exceptional abilities in idiot savants have been taken as evidence that innate talent accounts for exceptional performance. But recent research has shown that these exceptional abilities are more consistent with acquired skill than with innate talents (Howe, 1990). Training studies for memory for numbers (Chase & Ericsson, 1982), date calculation (Addis & O. Parsons, unpublished and described in Ericsson & Faivre, 1988), and mental calculation (Staszewski, 1988) have shown that within weeks, college students can attain levels of performance outside the range of normal adult performance.

Acute hepatitis may result from food containing aflatoxin B1 at levels of the order of 0 diabetes type 2 foot problems discount glipizide uk. The biosynthesis of aflatoxins proceeds through intermediates sterigmatocystin and versicolorin (see Figure 3 juvenile diabetes in dogs purchase glipizide online from canada. Toxins related to managing diabetes 445 order glipizide cheap these structures but differing in aromatic substituents are also produced by various fungi. The sterigmatocystins are synthesized by species of Aspergillus and Bipolaris, and contain a reduced bifuran fused to a xanthone, whilst the versicolorins from Aspergillus versicolor contain the same type of reduced bisfuran system but fused to an anthraquinone. Hexanoate is also likely to feature as a starter unit in the formation of the cannabinoids, a group of terpenophenolics found in Indian hemp (Cannabis sativa; Cannabaceae). This plant, and preparations from it, known under a variety of names including hashish, marihuana, pot, bhang, charas, and dagga, have been used for centuries for the pleasurable sensations and mild euphoria experienced after its consumption, usually by smoking. All the cannabinoid structures contain a monoterpene C10 unit attached to a phenolic ring having a C5 alkyl chain. Cyclization in the monoterpene unit necessitates a change in configuration of the double bond, and this may be rationalized as involving the allylic cation, which will then also allow electrophilic cyclization to proceed (for further detail see Figure 3. Cannabidiolic acid is the result of proton loss, whilst tetrahydrocannabinolic acid is the product from heterocyclic ring formation. The aromatic terpenoid derived ring in cannabinolic acid and cannabinol can arise via a dehydrogenation process (compare thymol, page 186). The plant is also grown for its narcotic and mild intoxicant properties, and in most countries of the world its possession and consumption is illegal. Over many years, cannabis plants have been selected for either fibre production or drug use, the former resulting in tall plants with little pharmacological activity, whilst the latter tend to be short, bushy plants. Individual plants are almost always male or female, though the sex is not distinguishable until maturity and flowering. The active principles are secreted as a resin by glandular hairs, which are more numerous in the upper parts of female plants, and resin is produced from the time flowers first appear until the seeds reach maturity. In a typical plant, the concentration of cannabinoids increases in the following order: large leaves, small leaves, flowers, and bracts (which surround the ovaries), with stems containing very little. Material for drug use (ganja) is obtained by collecting the flowering tops (with little leaf) from female plants, though lower quality material (bhang) consisting of leaf from both female and male plants may be employed. By rubbing the flowering tops, the resin secreted by the glandular hairs can be released and subsequently scraped off to provide cannabis resin (charas) as an amorphous brown solid or semi-solid. A potent form of cannabis, called cannabis oil, is produced by alcoholic extraction of cannabis resin. A wide variety of names are used for cannabis products according to their nature and the geographical area. The names grass, dope, pot, hash, weed, and wacky backy are more likely to be in current usage. The amount produced by various plants is dependent on several features, however, and this will markedly alter biological properties. Thus, in general, plants grown in a tropical climate produce more resin than those grown in a temperate climate. The tall fibre-producing plants are typically low resin producers, even in tropical zones. However, the most important factor is the genetic strain of the plant, and the resin produced may contain high levels of psychoactive compounds, or mainly inactive constituents. The major constituents in cannabis are termed cannabinoids, a group of more than 60 structurally related terpenophenolics. Many other cannabinoid structures have been characterized, including cannabigerol and cannabichromene (Figure 3. The latter compounds presumably arise from the use of butyrate rather than hexanoate as starter unit in the biosynthetic sequence. Cannabis leaf and resin stored under ordinary conditions rapidly lose their activity and can be essentially inactive after about 2 years. Any cannabinoid acids will almost certainly be decarboxylated upon heating, and thus the smoking process will also effectively increase somewhat the levels of active cannabinoids available. The smoking of cannabis produces a mild euphoria similar to alcohol intoxication, inducing relaxation, contentment, and a sense of well-being, with some changes in perception of sound and colour. However, this is accompanied by a reduced ability to concentrate and do complicated tasks, and a loss of short-term memory. Users claim cannabis is much preferable to alcohol or tobacco, insisting it does not cause dependence, withdrawal symptoms, or lead to the use of other drugs, and they campaign vociferously for its legalization. However, psychological dependence does occur, and cannabis can lead to hallucinations, depression, anxiety, and panic, with the additional risk of bronchitis and lung cancer if the product is smoked. Cannabis has been used medicinally, especially as a mild analgesic and tranquillzer, but more effective and reliable agents replaced it, and even controlled prescribing was discontinued. In recent times, cannabis has been shown to have valuable anti-emetic properties, which help to reduce the side-effects of nausea and vomiting caused by cancer chemotherapeutic agents. Cannabis has also been shown to possess properties which may be of value in other medical conditions. There is now ample evidence that cannabis can give relief to patients suffering from chronic pain, multiple sclerosis, glaucoma, asthma, migraine, epilepsy, and other conditions. Many sufferers who cannot seem to benefit from any of the current range of drugs are obtaining relief from their symptoms by using cannabis, but are breaking the law to obtain this medication. Current thinking is that cannabis offers a number of beneficial pharmacological responses and that there should be legal prescribing of cannabinoids or derivatives. In general, cannabis is only able to alleviate the symptoms of these diseases, and does not provide a cure. Recently, the ethanolamide of arachidonic acid (anandamide; ananda is the Sanskrit word for bliss) (Figure 3. Since this compound also interacts with the anandamide receptor, and levels of 2-arachidonoylglycerol in the brain are some 800 times higher than those of anandamide, it is now thought to be the physiological ligand for both receptors, rather than anandamide. The identification of these endogenous materials may open up other ways of exploiting some of the desirable pharmacological features of cannabis. They contain a linear tetracyclic skeleton of polyketide origin in which the starter group is malonamylCoA (Figure 3. Thus, in contrast to most acetate-derived compounds, malonate supplies all carbon atoms of the tetracycline skeleton, the starter group as well as the chain extenders. This organism typically produces chlortetracycline, whilst the parent compound tetracycline (Table 3. The use of mutants with genetic blocks has also enabled the shikimate pathway (Chapter 4) to be delineated. In that case, since a primary metabolic pathway was affected, mutants tended to accumulate intermediates and could not grow unless later components of the pathway were supplied. Chlortetracycline isolated from Streptomyces aureofaciens was the first of the group to be discovered, closely followed by oxytetracycline from cultures of S. Similarly, the early C-6 methylation step (included in a) can also be blocked, and such mutants accumulate 6-demethyltetracyclines.

In addition, some anticonvulsants are used in the emergency trea tment of sta tus epilepticus (a continuous seizure state). Treatment of epilepsy should begin with a single drug whose dosage is increa sed until seizures are controlled or a dverse rea ctions become problematic. Genera lly, a second alternative should be tried as monotherapy bef ore combination therapy is considered. The choice of drug trea tment depends on seizure type, drug cha racteristics, and patient preferences. Extensively protein -bound, ethotoin is excreted in urine, prim arily as metabolites. Pharmacodynamics In most cases, the hydantoin a nticonvulsants sta bilize nerve cells to keep them from getting overexcited. Phenytoin appears to work in the motor cortex of the brain, where it stops the spread of seizure activity. The pharmacodynamics of fosphenytoin and ethotoin are thought to mimic those of phenytoin. Pharmacotherapeutics Because of its ef fectiveness and relatively low toxicity, phenytoin is the m ost com monly prescribed a nticonvulsant. Adverse reactions to hydantoins Adverse rea ctions to hydantoins include: drowsiness ataxia irritability headache restlessness nystagmus dizziness a nd vertigo dysarthria nausea a nd vomiting abdominal pa in anorexia depressed atrial and ventricular conduction ventricular f ibrillation (in toxic states) bradycardia, hypotension, and ca rdiac arrest (with I. Hydantoins (phenytoin a nd f osphenytoin) are the long-acting anticonvulsant of choice to treat status epilepticus after initia l I. Resistance is futile Health ca re providers som etimes prescribe phenytoin and ethotoin in combination with other a nticonvulsants f or partial and tonic -clonic seizures in patients who are resistant to or intolerant of other a nticonvulsants. Phenoba rbital is som etimes used f or long-term treatment of epilepsy and is prescribed selectively to treat status epilepticus if hydantoins are ineffective. Other barbiturates Mephobarbital, a lso a long-acting barbiturate, is sometim es used as a n a nticonvulsant. Primidone, which is closely related chemically to the barbiturates, is also used to trea t chronic epilepsy. Pharmacokinetics Each ba rbiturate has a slightly different set of pharmacokinetic properties. The drug is 20% to 45% bound to serum proteins and to a similar extent to other tissues, including the brain. About 75% of a phenoba rbital dose is m etabolized by the liver, and 25% is excreted unchanged in urine. Mephobarbital undergoes extensive m etabolism by the liver; only 1% to 2% is excreted unchanged in urine. Pharmacodynamics Barbiturates exhibit anticonvulsant action a t doses below those tha t produce hypnotic effects. Barbiturates elevate the seizure threshold by decrea sing postsynaptic excitation. Pharmacotherapeutics Barbiturates are a n ef fective alternative thera py f or: P. The ma jor disadvantage of using phenobarbital f or status epilepticus is that it ha s a dela yed onset of a ction when an immediate response is needed. Adverse reactions to barbiturates Adverse rea ctions to phenobarbital and mephobarbital include: drowsiness, lethargy, a nd dizziness nystagmus, confusion, and ataxia (with large doses) laryngospasm, respiratory depression, and hypotension (when administered I. Because of monitoring, costs, and dosing frequency, phenobarbital is usually tried before primidone. The meta bolism of corticosteroids, digoxin, a nd estrogens may be enha nced when these drugs are ta ken with phenoba rbital, leading to decreased ef fects. It effectively treats: partial and generalized tonic -clonic seizures mixed seizure types complex partial seizures (drug of choice). Carbamazepine is distributed rapidly to all tissues; 75% to 90% is bound to plasma proteins. Pharmacotherapeutics Carbamazepine is the drug of choice, in adults and children, for trea ting: generalized tonic -clonic seizures simple a nd complex partial seizures. However, it relieves pain when used to treat trigeminal neura lgia (tic douloureux, cha racterized by excruciating facial pain along the trigeminal nerve) a nd may be useful in treating selective psychiatric disorders. Drug interactions Carbamazepine can reduce the ef fects of several drugs, including haloperidol, bupropion, lamotrigine, tricyclic antidepressants, oral anticoagulants, hormonal contraceptives, doxycycline, felbamate, theophylline, protease inhibitors, antipsychotics, and valproic acid. Other drug intera ctions can also occur: Increased carbamazepine levels and toxicity can occur with the use of cimetidine, danazol, diltiazem, erythromycin, isoniazid, selective serotonin reuptake inhibitors, propoxyphene, ketoconazole, valproic a cid, and verapamil. Carbamazepine levels may be decrea sed when ta ken with barbitura tes, felbamate, or phenytoin. Adverse reactions to carbamazepine Occasionally, ca rbamazepine ca n result in serious hematologic toxicity. Because carbamazepine is related structurally to the tricyclic a ntidepressants, it can cause similar toxicities and affect behaviors and emotions. Hives and Stevens -Johnson syndrome (a potentially f atal inflammatory disease) can a lso occur. Benzodiazepines the f our benzodiazepine drugs that provide a nticonvulsant effects are: clonazepam clorazepate diazepam (parenteral f orm) lorazepam. Diazepam m ay be used to trea t sta tus epilepticus or, in rectal form, repetitive seizures. Safe and sound Sound -alikes: Diazepam and lorazepam Be careful not to confuse the sound -alike drugs dia zepam a nd lora zepam. Metabolism and excretion Benzodiazepines a re metabolized in the liver to multiple metabolites and are then excreted in urine. Pharmacodynamics Benzodiazepines a ct as: anticonvulsants antianxiety agents sedative -hypnotics muscle rela xants. Pharmacotherapeutics Each of the benzodiazepines can be used in slightly different ways. Absence, atypical, and more Clonazepam is used to trea t the following types of seizures: absence (petit mal) atypical absence (Lennox-Gastaut syndrome) atonic myoclonic. Because diazepam provides only short -term ef fects of less than 1 hour, the patient must also be given a long-acting anticonvulsant, such as phenytoin or phenobarbital, during diazepam therapy. Adverse reactions to benzodiazepines Most common Drowsiness Confusion Ataxia Weakness Dizziness Nystagmus Vertigo Fainting Dysarthria Headache Tremor Glassy-eyed appearance Less common Depression of the heart and brea thing (with high doses a nd with I.

Thus diabetes type 1 apps buy generic glipizide, lovastatin can be formulated as arising from two polyketide chains with C-methylation as outlined in Figure 3 diabetic retinopathy stages generic glipizide 10mg without prescription. Accordingly diabete 5 per mille glipizide 10mg with visa, it is possible that lovastatin is formed by cyclization of the trienoic acid (Figure 3. High blood cholesterol levels contribute to the incidence of coronary heart disease (see page 236), so mevastatin, or analogues, are of potential value in treating high risk coronary patients, and some agents are already in use. Although lowering of cholesterol levels reduces the risk of heart attacks, there is evidence that the beneficial effects of statins may extend beyond simply cholesterol reduction. Simvastatin is obtained from lovastatin by ester hydrolysis and then re-esterification, and is two to three times as potent as lovastatin. Pravastatin is prepared from mevastatin by microbiological hydroxylation using Streptomyces carbophilus and is consequently more hydrophilic than the other drugs, with an activity similar to lovastatin. Other agents currently in use are synthetic, though they feature the same dihydroxycarboxylic acid side-chain as in pravastatin. The ester side-chain is derived as a separate unit from two acetates with a methyl from methionine, again with C-methylation preceding reduction processes. These proteins facilitate the chemical modification of substrates by virtue of binding properties conferred by a particular combination of functional groups in the constituent amino acids. As a result, enzymes tend to demonstrate quite remarkable specificity towards their substrates, and usually catalyse only a single transformation. This specificity means enzymes do not accept alternative substrates, or, if they do, they convert a limited range of structurally similar substrates and usually much less efficiently. Any particular organism thus synthesizes a range of secondary metabolites dictated largely by its enzyme complement and the supply of substrate molecules. A good example of this approach is in the directed biosynthesis of modified penicillins by the use of phenylacetic acid analogues in cultures of Penicillium chrysogenum (see page 437), but its scope is generally very limited. It has also been possible, particularly with microorganisms, to select natural mutants, or to generate mutants artificially, where the new strain synthesizes modified or substantially different products. For example, mutant strains of Streptomyces aureofaciens synthesize tetracycline or demeclocycline rather than chlortetracycline (see page 90). Such mutants are usually deficient in a single enzyme and are thus unable to carry out a single transformation, but the broader specificity of later enzymes in the sequence means subsequent modifications may still occur. However, as exemplified throughout this book, the vast bulk of modified natural products of medicinal importance are currently obtained by chemical synthesis or semi-synthesis. Rapid advances in genetic engineering have now opened up tremendous scope for manipulating the processes of biosynthesis by providing an organism with, or depriving it of, specific enzymes. The genes encoding a particular protein (see page 407) can now be identified, synthesized, and inserted into a suitable organism for expression; to avoid complications with the normal biosynthetic machinery, this is usually different from the source organism. Specific genes can be damaged or deleted to prevent a particular enzyme being expressed. Genes from different organisms can be combined and expressed together so that an organism synthesizes abnormal combinations of enzyme activities, allowing production of modified products. Although the general approaches for genetic manipulation are essentially the same for all types of organism and/or natural product, it has proved possible to make best progress using the simpler organisms, especially bacteria, and in particular there have been some substantial achievements in the area of acetatederived structures. Accordingly, some results from this group of compounds are used to exemplify how genetic manipulation may provide an extra dimension in the search for new medicinal agents. However, it is important that an organism is not viewed merely as a sackful of freely diffusible and always available enzymes; biosynthetic pathways are under sophisticated controls in which there may be restricted availability or localization of enzymes and/or substrates (see the different localizations of the mevalonate and deoxyxylulose phosphate pathways to terpenoids in plants, page 172). Enzymes involved in the biosynthesis of many important secondary metabolites are often grouped together as enzyme complexes, or may form part of a multifunctional protein. Type I enzymes consist of one or more large multifunctional proteins that possess a distinct active site for every enzyme-catalysed step. The usual starter units employed are acetylCoA or propionyl-CoA, whilst malonyl-CoA or methylmalonyl-CoA are the main extender units. The linear sequence of modules in the enzyme corresponds to the generated sequence of extender units in the polyketide product. Genetic engineering now offers vast opportunities for rational modification of the resultant polyketide structure. A few representative examples of successful experiments leading to engineered polyketides are shown in Figure 3. Reducing the size of the gene sequence so that it encodes fewer modules results in the formation of smaller polyketides, characterized by the corresponding loss of extender units; in these examples the gene encoding the chain terminating thioesterase also has to be attached to complete the biosynthetic sequence. Not all experiments in gene modification are successful, and even when they are yields can be disappointingly lower than in the natural system. There is always a fundamental requirement that enzymes catalysing steps after the point of modification need to have sufficiently broad substrate specificities to accept and process the abnormal compounds being synthesized; this becomes more unlikely where two or more genetic changes have been made. Nevertheless, multiple modifications have been successful, and it has also been possible to exploit changes in a combinatorial fashion using different expression vectors for the individual subunits, thus creating a library of polyketides, which may then be screened for potential biological activity. However, because of the highly reactive nature of poly-keto chains, the cyclizations that occur with the modified gene product frequently vary from those in the original compound. These enzymes differ from the other examples in that they are homodimeric proteins, they utilize coenzyme A esters rather than acyl carrier proteins, and they employ a single active site to perform a series of decarboxylation, condensation, cyclization, and aromatization reactions.

Griseofulvin is fungistatic and treatment for infected nails has to be prolonged (an average of 12 months for fingernails, and at least 18 months for toenails). It is effective in tinea corporis, cruris and pedis; and also in nail infections, although without a licence for this use in many countries. Fungistatic rather than fungicidal, it interferes with the cytochrome P-450 system, so a review of any other medication being taken is needed before a prescription is issued. Even in transient and trivial local infections in the apparently fit, one or more predisposing factors such as obesity, moisture and maceration, diabetes, pregnancy, the use of broad-spectrum antibiotics, or perhaps the use of the contraceptive pill, will often be found to be playing some part. Opportunism is even more obvious in the overwhelming systemic infections of the immunocompromised. Oral candidiasis (see also Chapter 13) One or more whitish adherent plaques (like bread sauce) appear on the mucous membranes. Candida intertrigo A moist glazed area of erythema and maceration appears in a body fold; the edge shows soggy scaling, and outlying satellite papulopustules. These changes are most common under the breasts, and in the armpits and groin, but can also occur between the fingers of those whose hands are often in water. Genital candidiasis Most commonly presents as a sore itchy vulvovaginitis, with white curdy plaques adherent to the inflamed mucous membranes, and a whitish discharge. Conjugal spread is common; in males similar changes occur under the foreskin. Paronychia Acute paronychia is usually bacterial, but in chronic paronychia Candida may be the sole pathogen, or be found with other opportunists such as Proteus or Pseudomonas. The proximal and sometimes the lateral nail folds of one or more fingers become bolstered and red (see. Predisposing factors include wet work, poor peripheral circulation and vulval candidiasis. Chronic mucocutaneous candidiasis Persistent candidiasis, affecting most or all of the areas described above, can start in infancy. Several different forms have been described including those with autosomal recessive and dominant inheritance patterns. Systemic candidiasis this is seen against a background of severe illness, leucopenia and immunosuppression. The skin lesions are firm red nodules, which can be shown by biopsy to contain yeasts and pseudohyphae. In chronic mucocutaneous candidiasis, a detailed immunological work-up will be needed, focusing on cell-mediated immunity. Amphotericin, nystatin and the imidazole group of compounds are all effective topically. For the mouth, these are available as oral suspensions, lozenges and oral gels (Formulary 1, p. False teeth should be removed at night, washed and steeped in a nystatin solution. For other areas of candidiasis, creams, ointment and pessaries are available (Formulary 1, p. In chronic paronychia, the nail folds can be packed with an imidazole cream or drenched in an imidazole solution several times a day. Both are also valuable for recurrent oral candidiasis of the immunocompromised, and for the various types of chronic mucocutaneous candidiasis. Pityriasis versicolor Cause the old name, tinea versicolor, should be dropped as the disorder is caused by commensal yeasts (Pityrosporum orbiculare) and not by dermatophyte fungi. Overgrowth of these yeasts, particularly in hot humid conditions, is responsible for the clinical lesions. Carboxylic acids released by the organisms inhibit the increase in pigment production by melanocytes that occurs normally after exposure to sunlight. Presentation and course the fawn or depigmented areas, with their slightly branny scaling and fine wrinkling, look ugly. Untreated lesions persist, and depigmented areas, even after adequate treatment, are slow to regain their former colour. Seborrhoeic eczema of the trunk tends to be more erythematous, and is often confined to the presternal or interscapular areas. Pityriasis rosea, tinea corporis, secondary syphilis and erythrasma seldom cause real confusion. Investigations Scrapings, prepared and examined as for a dermatophyte infection (p. Treatment A topical preparation of one of the imidazole group of antifungal drugs (Formulary 1, p. This should be lathered on to the patches after an evening bath, and allowed to dry. For widespread or stubborn infections systemic itraconazole (200 mg daily for 7 days) has been shown to be curative, but interactions with other drugs must be avoided (Formulary 2, p. Deep fungal infections Histoplasmosis Histoplasma capsulatum is found in soil and in the droppings of some animals. Airborne spores are inhaled and cause lung lesions, which are in many ways like those of tuberculosis. Later, granulomatous skin lesions may appear, particularly in the immunocompromised. Its spores are inhaled, and the pulmonary infection may be accompanied by a fever. In a few patients the infection becomes disseminated, with ulcers or deep abscesses in the skin. Rarely, the organism is inoculated into the skin; more often it is inhaled and then spreads systemically from the pulmonary focus to other organs including the skin. There the lesions are wart-like, hyperkeratotic nodules, which spread peripherally with a verrucose edge, while tending to clear and scar centrally. Sporotrichosis the causative fungus, Sporotrichum schencki, lives saprophytically in soil or on wood in warm humid countries. Actinomycosis the causative organism, Actinomyces israeli, is bacterial but traditionally considered with the fungi. It has long branching hyphae and is part of the normal flora of the mouth and bowel. Mycetoma (Madura foot) Various species of fungus or actinomycetes may be involved. They gain access to the subcutaneous tissues, usually of the feet or legs, via a penetrating wound. The area becomes lumpy and distorted, later enlarging and developing multiple sinuses.

Some aspects of sports nutrition are common to all sporting activities, but there are obviously differences between various sports. In football, however, it is less easy to quantify performance: measurement of team performance in terms of the number of matches won and lost tells little about the performance of individual players. Nutrition is no substitute for fitness or skill, but it can help players to make the most of their abilities. In most matches, the competition is structured so that there is little difference between the two teams, and when teams are evenly matched in terms of skill, fitness and determination, good nutrition can make the difference between winning and losing. It is therefore surprising that some players seem not to be concerned about their diet: there is often a lack of knowledge of basic nutrition and of awareness about the food choices that should be made. Fitness is obviously important in allowing the player to last the full 90 minutes of a match, and improving fitness is an important part of the preparation for competition. Conversely, performance may be improved by dietary manipulation, but we still have an incomplete understanding of how best to control diet to optimise sports performance. Not all football players follow a diet that will allow them to sustain optimum performance in training and competition. Throughout the season, which now lasts for almost 12 months for top-class players, some training is carried out most days of the week, and the training load has a significant effect on energy balance. If energy intake is inadequate, players will suffer from chronic fatigue and illness and will not adapt effectively to training. There have been few studies on the dietary intakes of football players, and dietary surveys are generally prone to methodological flaws. However, the available data suggests that football players, even at professional level, have moderate energy requirements relative to those in some other sports, with intakes being typically about an adequate intake of protein, vitamins and minerals. The mean values indicate that the composition of the diet is not very different from that of the general population, but there are some individuals within this group whose diet provides inadequate amounts of carbohydrate, too much fat or too much alcohol. Two distinct aspects must be considered: the first is the diet in training, which must be consumed on a daily basis for a large part of the year, and the second is the diet in the immediate pre-match period and during the competition itself. It is common during pre-season training for energy intake to be restricted and energy expenditure to be increased to achieve the optimum playing body mass and to reduce body fat content if this is too high. Large energy deficits, however, lead to an inability to continue training at a high level, and an increased risk of injury, so regular monitoring of body mass and body fat content over the season is recommended to ensure that weight loss is gradual (no more than about 0. While it is undoubtedly true that an inadequate amount of protein will lead to a loss of muscle tissue, excess dietary protein alone will not drive the system in favour of increasing muscle mass. Athletes will need more than this, but there is no evidence that more than twice this amount (more than about 1. Hard training does lead to an increase in the minimum daily protein requirement, but this will be met if a varied diet that contains items from all of the major food groups is eaten in sufficient amounts to meet the increased energy expenditure. A diet that is based largely on nutrientrich foods, including vegetables, fruits, beans, legumes, cereals, lean meat, fish and dairy foods, should ensure that sufficient protein is consumed, as well as meeting needs for vitamins and minerals. Prevention Football Medicine Manual 125 room in the diet for the carbohydrate that is needed to fuel the working muscles. The energy requirements of training are largely met by oxidation of fat and carbohydrate. Both training and match play involve repeated short, intense sprints and these rely largely on carbohydrate as a fuel. Towards the end of a training session, when the carbohydrate (glycogen) content of the liver and the muscles is low, it becomes more difficult to maintain the training intensity. There is some evidence that increased rates of muscle injury are also associated with exercise performed in the fatigued state, but it is difficult to obtain clear evidence to confirm or deny this suggestion. During each strenuous training session, substantial depletion of the glycogen stores in the exercising muscles and in the liver takes place. If this carbohydrate reserve is not replenished before the next training session, training intensity must be reduced, leading to corresponding decrements in the training response. Suggested targets for carbohydrate intake are to ensure about 5-7 g/kg/d during periods of moderate intensity training, and to aim for 7-10 g/kg/d during recovery from hard training (such as in pre-season). The primary requirement during periods of intensive training, therefore, is for the carbohydrate intake to be sufficient to enable the training load to be sustained at the high level necessary to improve fitness. The training diet should be high in carbohydrate to meet the high requirement; this suggestion conforms to recommendations that, in a healthy diet for the average individual, carbohydrates should make up at least 50% of the diet. The recommendation for carbohydrate intake has traditionally been made as a fraction of the total energy intake, but it seems more appropriate to think of an absolute requirement related to the total amount of carbohydrate used during training and other daily activities. For a typical 70kg player, a carbohydrate intake of 500-600 grams per day (which might correspond to less than 50% or more than 70% of the total energy intake) may be necessary to maximise muscle and liver glycogen stores between daily training sessions (or between matches that are close together). Many players find it difficult to eat two or three hours before training and the appetite is likely to be suppressed for some time after exercise. Choosing foods that are practical and appealing is important in a busy lifestyle and where the player cannot rely on hunger to govern food intake. Of course, this will depend on individual preferences, and many different foods can be chosen to meet energy needs and to provide the essential nutrients. Players may need to seek professional advice from a qualified sports dietitian to ensure that they make the best choices. If nutritious carbohydrate-rich foods are eaten in sufficient quantity to meet energy needs, the diet should supply more than adequate amounts of protein, minerals, vitamins and other dietary components to meet any increase in requirements resulting from the training load. Inadequate nutrient intake may occur when the energy intake is restricted by chronic or over-zealous weight loss programmes, or when the diet lacks variety. Some players do not eat a varied diet in a sufficient amount to meet their needs, and dietary deficiencies may occasionally be encountered. For many players, a regular routine is an important part of their lifestyle, and this may lead to repetitive food choices and meal plans. Fad diets, disordered eating habits, perfectionism about eating only "good foods", poor nutrition knowledge, a lack of food preparation skills and limited access to food may all restrict food variety. Players should practise drinking during training: this helps them to cope with training, but also ensures that their individual hydration strategy for training and match play can be defined. The individual hydration strategy should consider the individual sweating rate of a player and their preferences for fluid intake and particular drinks. The general aim for all players should be to limit weight loss during match play to not more than about 2% of body mass. Prevention Football Medicine Manual How to estimate sweating rate: 1) Measure body weight (kg) both before and after at least one hour of exercise under conditions similar to competition or a hard practice. Towel dry after exercise and obtain body weight as soon as is practical after exercise.

The April and May protests were mostly peaceful managing juvenile diabetes glipizide 10 mg sale, but there were sporadic clashes between police and protesters diabetes symptoms feet and ankles discount 10mg glipizide otc, including on April 16 when police allegedly used stun grenades diabetes mellitus zuckerkrankheit symptome buy glipizide pills in toronto, leaving 46 people injured, including six policemen. Police also arbitrarily arrested hundreds of protest participants, including protest leader Pashinyan, based on accusations of participation in mass riots or holding rallies in violation of the established rules. In June, they brought charges against a policeman accused of seriously ill-treating, in a court basement, four defendants in a trial concerning the violent takeover of a Yerevan police station in July 2016. Authorities also revived the investigation into the March 2008 deadly clashes between protesters and security forces, that left 10 people dead, including two policemen. Following the renewed investigation, authorities brought criminal charges against three former high-level officials, including ex-President Robert Kocharyan, and two commanders, Michael Harutyunyan and Yuri Khachaturov, accusing them of attempting to overthrow the constitutional order. A court initially remanded Kocharyan to pretrial detention, but he was released upon appeal, pending completion of the investigation. In September, authorities suspended the investigation into the July 2016 police violence against protesters. Courts previously convicted 21 protesters, while no officials faced criminal charges. However, in July, authorities brought criminal charges against one policeman for abuse of office. Authorities continue to implement their commitment to full inclusive education by 2025. Inclusive education involves children with and without disabilities studying together in community schools. Despite some progress, children with disabilities continue to face segregation and stigma, and do not always receive reasonable accommodation in schools to enable them to study on an equal basis with other children. According to police, during the first five months of 2018 they recorded 864 incidents of violence against women, of which 223 were cases of domestic violence. Authorities brought charges against 31 persons for domestic violence through July, and courts convicted seven. In January, a new law on violence in the family entered into force, providing a definition of domestic violence, but including notions of "strengthening traditional values" and "restoring family harmony" as key principles. In February, the government approved the action plan for the implementation of the law, and in June set up the Council on Prevention of Violence in the Family, the coordination body for policies on prevention of domestic violence. Authorities also drafted relevant decrees regulating requirements for shelter staff members, and for establishing a centralized record on domestic violence cases. Authorities still need to increase the number of shelter spaces and establish state-run shelters, and conduct campaigns to educate the public about the new law, how to file complaints, and the availability of services. In January, Armenia signed, but still has to ratify, the Council of Europe (CoE) Istanbul Convention on Prevention and Combating Violence against Women and Domestic Violence (Istanbul Convention). Disability Rights the government continues to transform some residential institutions for children into community centers and to support family-based care, but these programs do not include children with disabilities on an equal basis with other children. Existing legislation allows for deprivation of legal capacity of persons with psychosocial or intellectual disabilities and there are no supported decision-making mechanisms in place. Hateful and derogatory comments circulated on social media regarding the private visit to the country in May of musician Elton John and his husband. The assailants ran after Hayk Hakobyan and his fellow activists, as they tried to escape, hitting, kicking, throwing stones, and shouting profanities, injuring six. The criminal code does not recognize homophobia as an aggravating criminal circumstance, and a government bill on equality does not include sexual orientation and gender identity as grounds for protection from discrimination. Openly gay men fear for their physical security in the military, and some seek exemption from serving in the army. An exemption, however, requires a medical conclusion finding them "psychologically or mentally unfit" to serve. Among other things, he urged Armenian authorities to introduce comprehensive infrastructure for the healthcare of children with disabilities to support families, instead of large institutions for children. He also called on authorities to stop prioritizing investments in large psychiatric hospitals and residential institutions for people with mental health conditions, and increase investments in alternative mental health services. In its May 2017 combined periodic report on Armenia, the United Nations Committee on the Elimination of Racial Discrimination welcomed the constitutional reform, and urged authorities to further amend the legislation to bring it in line with the Convention on Elimination of Racial Discrimination, including by introducing a new definition of hate crime in state law, and reviewing the quota system to allow for greater representation of minorities in parliament. During a September visit, CoE Human Rights Commissioner Dunja Mijatovic called on the government to guarantee legal capacity, phase out institutions, and ensure quality, inclusive education for persons with disabilities. In 2018, the government continued to hold refugees and asylum seekers who arrived by boat in Australian waters on Manus Island in Papua New Guinea and on Nauru, marking more than five years since the reintroduction of its draconian offshore processing and settlement policy. In October, the Queensland government introduced a human rights act, becoming the third jurisdiction in Australia to do so behind the Australian Capital Territory and Victoria. More than 150 other refugees and asylum seekers have been transferred only after lawyers threatened urgent court proceedings. These cases include children as young as 10 who suffer from acute mental health conditions, some of whom have attempted suicide. In July, a Queensland inquest found that the death of Iranian asylum seeker Hamid Khazaei on Manus Island in 2014 was preventable. In March 2018 Dutton also commented that persecuted white South African farmers deserved "special attention" on humanitarian grounds from a "civilised country" like Australia. Countries of origin include Afghanistan, Myanmar, Iran, Pakistan, Somalia, and Sudan. Many refugees and asylum seekers suffer from poor mental health or mental illness due to, or exacerbated by, years of detention and uncertainty about their futures. At least 12 refugees and asylum seekers have died on Manus Island and Nauru since 2013. Two refugees with mental health conditions reportedly committed suicide on Manus and Nauru in 2018. At time of writing, the government, reacting to the change in popular opinion, had relocated more than 100 children from Nauru to Australia between August and November. Australian courts have ordered the government to transfer more than 90 refugees and asylum seekers in poor Indigenous Rights Indigenous Australians are significantly overrepresented in the criminal justice system, often for minor offenses like unpaid fines. In March, the Australian Law Reform Commission recommended that the government develop national criminal justice targets to reduce incarceration rates of indigenous people, and abolish discriminatory laws like mandatory sentencing and end the practice of imprisonment for unpaid fines-which disproportionately impacts indigenous women. In September, the government introduced legislation that would undermine strong encryption and cybersecurity, allowing law enforcement and security agencies to order technology companies and even individuals to facilitate access to encrypted data and devices. The law would give officials wide discretion to decide whether an order is "reasonable and proportionate. Australian states and territories set the age of criminal responsibility at 10-yearsold. Across Australia, around 600 children under the age of 14 are imprisoned each year, mostly Indigenous. In March, the Northern Territory announced support "in principle" for the royal commission recommendation to raise the age from 10 to 12, but at time of writing had yet to implement it. In April, the inspector of custodial services released a report into conditions at Banksia Hill youth detention center in Western Australia, and found that two boys were "probably" held in solitary confinement in breach of the United Nations Convention against Torture. Disability Rights More than half the Australian prison population has a physical, sensory, psychosocial (mental health), or cognitive disability. In particular, Aboriginal and Torres Strait Islander people are 13 times more likely to be imprisoned than the rest of the Australian population and are more likely to have a disability. People with disabilities struggle to cope in often- overcrowded prisons without adequate access to support services, and are particularly at risk of neglect and abuse.

Exposure to diabetes medications how they work order 10mg glipizide free shipping natural or artificial light before the trough in core temperature promotes a phase delay whereas a phase advance is encouraged by light administered after this time diabetes test strips cost purchase 10mg glipizide with amex, meaning "body-clock time" canine diabetes in young dogs generic 10mg glipizide with mastercard. Where natural daylight cannot be exploited, artificial light from visors or light boxes can be effective for phase-shifting purposes. In contrast, dark glasses or dark rooms should be used at times when light should be avoided (see Figure 2. Exercise itself may act to re-synchronise the body clock but is likely to be more effective for inducing a delay than for an advance. Behavioural strategies for coping with jet lag depend to some extent on the direction of flight. A flight westwards requires a phase delay, and after arrival, light training Figure 2. Prevention Football Medicine Manual the return journey Once the competition is over, the immediate focus must be on the return journey and promoting recovery from competitive exertions. The travel strategy is not simply a duplication of activities on the outward journey since the direction of flight and the new itinerary must be taken into account. The time the match ends and the distance to the nearest convenient airport are also relevant. For matches that end late in the evening, the group may stay on overnight in its accommodation and participate in light training the following morning before returning home. Where it is feasible, some teams prefer to return home straightaway after the match. In this case, the players can compensate for sleep deprivation by "sleeping in" the next morning and training at a low to moderate intensity in the afternoon. For long-haul flights across multiple meridians, sleep can be attempted on board the plane and a behavioural strategy adopted for re-adjustment of the body clock to the home country. Overview Travel across vast distances is now common among football teams for recreational, training or competitive purposes. International players are especially subject to arduous itineraries that entail playing matches in both the home country and the new environment. Knowledge of chronobiological principles can help to manage the fatigue due to travel stress and to cope with jet lag when journeys are across multiple time zones. Guidelines can be drawn up for individual journeys, in preference to generic advice, to help ameliorate the effects of jet lag and improve coping mechanisms. An education programme can assist in guiding individual players in cases of difficult journeys away from their clubs. It could include advice about preparing for the journey, behaviour on-board the flight and following arrival. There is no single cure for jet lag and modifications of diurnal activity are likely to be more effective than using sedatives or hypnotics. Exposure to and avoidance of bright light at the appropriate times, coupled with the correct timing of training, are key elements of a coping strategy. Support personnel and officials should be included, as well as the players, when travel strategies are being drawn up. Attention to detail should help ensure that a successful journey is not marred by discomfort and performance impairment during the trip. During the last fifteen years, prominent doping cases, particularly in individual sports, have alerted the public to the problem of doping. As suspicion grew of greater drug abuse at all levels, including amateurs and recreational sportsmen, doping increasingly became a concern for international and national sports organisations and governments alike. However, public discussion is not always characterised by expertise and insight into the complexity of doping in sports. The team physician obviously plays a crucial role in the fight against doping and medication abuse in football. He educates players and coaches in nutrition, supplements and the allowed means of performance enhancement. He leads by example through his prescription attitude and knows about the health risks of doping substances and medications alike. This includes using (taking or injecting), administering or prescribing prohibited substances prior to or during a competition. These stipulations also apply for out-of-competition testing of anabolic steroids and peptide hormones, as well as for substances producing similar effects. Any decisions and regulations are based on the specifics of the game, scientific evidence and the analysis of validated doping statistics. The magnitude of doping in football Any discussion of anti-doping strategies should be based on risk assessment and established facts. Prevention Football Medicine Manual each for ephedrine, cannabis and nandrolone, an incidence of 0. The total number of samples collected and analysed in football during the year allows the total incidence of positive samples (2004: 0. Over the years, cannabis and cocaine have accounted for about 80% of positive test results, whilst in 2007 about 61% of positive samples were due to cannabis and cocaine (Figure 2. The relatively low incidence of positive doping samples, particularly for true performance-enhancing drugs such as anabolic steroids (2004: 0. It is often speculated that team sports such as football are not as prone to abuse of performanceenhancing substances as individual sports for a number of reasons, and this seems to be affirmed by the high number of positive cases in individual sports at the Olympic Games as compared to team sports. It remains to be seen how the extension of out-of-competition testing will influence statistics, although the results of such testing. They can enhance explosive power and endurance performance because one can exercise more strenuously and be less sensitive to pain.
