Approach patient and explain the procedure, and thereafter, allow patient to ask questions and discuss any problems which have arisen previously. Identify patient, making sure the information matches the details on the requisition form. Reassure patient that the minimum amount of blood required for testing will be drawn 4. Position patient with the chosen arm extended to form a straight line from shoulder to wrist, with the patient assisting by clenching and unclenching the fist. Select appropriate vein for venepuncture and do not attempt a venepuncture more than twice. Apply the tourniquet 3-4 inches above the collection site, if a tourniquet is used for preliminary vein selection, release it and reapply after two minutes and never leave tourniquet on for over one minute. Clean puncture site by making a smooth circular pass over the site with the 70% alcohol pad, allow to dry. Anchor vein by applying manual traction and the insert needle smoothly at an 0 angle of 20-30. Holding the hub securely, insert the first vacutainer tube following proper order of draw into the large end of the hub penetrating the stopper. Blood should flow into the evacuated tube, after blood starts to flow release the tourniquet and ask patient to unclench hand. When blood stops flowing, remove the tube by holding hub securely and pulling the tube off the needle. If multiple tubes are needed, the proper order of draw to avoid cross contamination and erroneous results is as follows: 13. Each coagulation tube (light blue top) should be gently inverted 4 times after being removed from the hub. Place a gauze pad over the puncture site and remove the needle, and immediately apply slight pressure. Properly dispose of hub with needle attached into a sharps bin label all tubes with patient labels, initials, date and time.

It is evident that vitamin D exerts important pleiotropic effects distinct from its primary role in calcium and phosphate homeostasis, and bone metabolism. Deficient vitamin D status has previously been associated with increased cardiovascular disease risk, therefore the effect of vitamin D supplementation on cardiovascular risk markers, especially endothelial dysfunction and inflammation, are important areas for investigation. Included studies were identified by conducting a literature search of randomised controlled trial articles published from 2008 to 2014, using Cochrane, Pubmed and Medline electronic databases with the search terms related to vitamin D and endothelial function. Among the 1107 studies retrieved, 27 studies met the full inclusion criteria for this systematic review. Overall, eight studies reported significant improvements in the endothelial/inflammatory biomarkers and parameters measured. However, the positive effect disappeared by the second period of measurement in two out of the eight studies. The remaining 19 trial studies did not show significant improvements in the biomarker/parameters of interest measured. Although some studies showed significant improvement in the markers of interest, evidence from most of the studies included in this systematic review did not demonstrate that vitamin D supplementation in adults’ results in improvement of circulating inflammatory and endothelial function biomarkers/parameters.

The disease name refers to the fact that at the end of the disease, the brain is full of holes like a sponge. The disease may develop in a relatively short time or, as is more usual, will take decades to develop. In general, as in cattle, diseased animals lose coordination of their legs and body movements and eventually cannot stand. The name "scrapie" refers to the fact that the animals can become irritable and develop an intense itch. They can be genetic diseases that run in families, a mutation that happens sporadically in individuals and probably animals as well, or they may be transmitted by ingestion of the infectious agent. There is still some controversy regarding the nature of the transmissible agent that causes these fatal conditions, but the most accepted theory is that the agent is a modified form of a normal cell surface component known as a prion (proteinaceous infectious articles and (pronounced preeon) protein) (PrP). This modified version of PrP is disease causing, and is both less soluble and more resistant to enzyme degradation then the normal protein. Prusiner also states that "prions appear to multiply in an incredible way: they convert normal protein molecules into dangerous ones (PrPsc) simply by inducing the benign molecules to change their shape. Prions made of different proteins may contribute to other neurogenerative diseases that are quite prevalent in humans. It is not definitive that the disease originated from scrapie infected meat and bone meal that was used as a protein supplement in cattle feeds, but there is strong evidence and general agreement that the outbreak was amplified by feeding rendered infected cattle meat-and-bone meal to young calves. Lower incidences have occurred in indigenous cattle in Ireland, France, Switzerland, the Netherlands, and Portugal. A few cases have been recorded in Canada, 2 Germany, Denmark, Italy, the Falkland Islands, and the Sultanate of Oman in animals exported from Great Britain.

It is more likely medications zoloft side effects cyklokapron 500mg amex, however treatment in statistics buy cheap cyklokapron 500mg on-line, that in most cases the disorder is related to hormonal alterations treatment quietus tinnitus 500mg cyklokapron with mastercard. The role of hormonal factors in the pathogenesis of chorea is further exemplified by the association of choreic disorder associated with oral contraceptive use (33 treatment plan for ptsd proven cyklokapron 500 mg, 34) symptoms viral meningitis cyklokapron 500 mg. Cho rea usually begins soon after the patient has started taking oral con traceptives and stops within a few weeks after they are discontinued medications borderline personality disorder order 500mg cyklokapron visa. Nearly half the patients have a history of previous chorea symptoms liver cancer purchase 500mg cyklokapron with mastercard, which may have been associated with a rheumatic attack or with nonrheumatic conditions oxygenating treatment purchase cheap cyklokapron on line. Interestingly, patients with oral contraceptive-induced chorea who later became pregnant do not necessarily develop chorea gravidarum. In addition to the above-mentioned causes of choreiform movements, simple motor tics in children or the involuntary jerks of Tourette’s syndrome may be confused with chorea. The duration of chorea is quite variable, ranging from one week to more than two years; the median duration of an attack was 15 weeks in hospitalized patients. A number of long-term neurological and psycho logical sequelae have been described, including convulsions, de creased learning ability, behavior problems, and psychosis. The subcutaneous nodules are round, firm, freely movable, painless lesions varying in size from 0. Because the skin over them is not inflamed, they may easily be missed if not carefully sought on physical examination. They may also be found over the scalp, especially the occiput, and the spinous processes of the vertebrae. In most cases, they are associated with the presence of carditis, usually appearing several weeks after the onset of cardiac findings. Nodules are found more frequently in patients with severe carditis and may appear in recur rent corps (36). In view of the evanescent nature of the lesions and the lack of associated symptoms, however, erythema marginatum may be missed if not specifically sought, particularly in dark-skinned patients. The lesions of erythema marginatum appear first as a bright pink macule or papule that spreads outward in a circular or seripiginous pattern. The lesions are multiple, appearing on the trunk or proximal extremities, rarely on the distal extremities, and never on the face. They are nonpruritic and nonpainful, blanch under pressure, and are only rarely raised. Individual lesions may come and go in minutes to hours, at times changing shape before the observer’s eye or coalescing with adjacent lesions to form varying patterns. Indeed, they have been described as appearing like “smoke rings” beneath the skin. It may, however, persist or recur for months or even years, continuing after other manifestations of the disease have sub sided, and it is not influenced by anti-inflammatory therapy. This cutaneous phenomenon is associated with carditis but, unlike subcu taneous nodules, not necessarily with severe carditis. It must be 35 differentiated from other toxic erythemas in febrile patients and the rash of juvenile rheumatoid arthritis. The circinate rash of Lyme disease (erythema chronicum migrans) may resemble erythema marginatum. Fever occurs in almost all rheumatic attacks at the onset, usually ranging from 101°F to 104°F (38. Children who present only with mild carditis without arthritis may have a low-grade fever, and patients with pure chorea are afebrile. The pain usually involves large joints, may be mild or incapacitating, and may be present for days to weeks, often varying in severity. However, they may be of considerable clinical importance because they often appear hours or days before major manifestations of the disease and may mimic a variety of other acute abdominal conditions. The pain is usually epigastric or periumbilical, but may be accompanied by guard ing and at times can be virtually indistinguishable from acute appen dicitis. Both the temperature and sedimentation rate tends to be higher than in appendicitis, but if the latter cannot be excluded, surgery may be necessary. New diagnostic techniques for rheumatic carditis Echocardiography the use of echocardiography to detect rheumatic carditis is discussed in the following Chapter 4, entitled, Diagnosis of rheumatic fever and assessment of valvular disease using echocardiography. The results demonstrated that myocarditis was virtually absent (defined by the Dallas criteria to be focal or diffuse myocytic necrosis associated with cellular infiltration of mononuclear lymphocytes). Instead, there was evidence of intersti tial inflammation that ranged from perivascular mononuclear cellular infiltration, to histiocytic aggregates and Aschoff nodule formation. Histiocytic aggregates and Aschoff nodules were identified in only 30% of patients. Radionuclide imaging Radionuclide techniques are simple, noninvasive modalities that have been commonly used to evaluate a variety of cardiovascular disorders. The pathology of rheumatic myocarditis is characterized predominantly by the presence of myocardial inflammation, with some damage to myocardial cells (39, 40). Gallium-67 (41), radiola belled leukocytes (42, 43), and radiolabelled antimyosin antibody (44) have all been used to image myocardial inflammation. However, the results of these studies have revealed that gallium 67 imaging has better diagnostic characteristics than antimyosin scin tigraphy; and the results also confirmed that rheumatic carditis is predominantly infiltrative, rather than degenerative, in nature.

The clinical picture of rheumatic fever: diagnosis, immediate prognosis, course and therapeutic implications. Diagnosis of rheumatic fever and assessment of valvular disease using echocardiography the advent of echocardiography Echocardiography is an imaging technique that rapidly evolved and matured, and currently it is a key component in the diagnosis of heart disease. The technique includes transthoracic, transesophageal and intracardiac echocardiography (1–3). Three-dimensional and even four-dimensional echocardiography have also been developed (4). To diagnose rheumatic carditis and assess valvular disease, however, M-mode, two-dimensional (2D), 2D echo-Doppler and colour flow Doppler echocardiography are sufficiently sensitive and provide specific information not previously available. Of these, M-mode echocardiography provides parameters for assessing ventricular func tion, while 2D echocardiography provides a realistic real-time image of anatomical structure. Two-dimensional echo-Doppler and colour flow Doppler echocardiography are most sensitive for detecting abnormal blood flow and valvular regurgitation. The use of 2D echo-Doppler and colour flow Doppler echo cardiography may prevent the overdiagnosis of a functional murmur as valvular heart disease (5). Similarly, the overinterpretation of physiological or trivial valvular regurgitation may result in a misdiag nosis of iatrogenic valvular disease (6, 7). Echocardiography and physiological valvular regurgitation Two-dimensional echo-Doppler and colour flow Doppler echo cardiography have permitted all audible valvular regurgitation to be detected, even the physiological, functional, trivial or so-called “nor mal” flow disturbance that may occur when normal valves close (7– 11). Utilizing colour flow Doppler echocardiography, physiological regurgitation is characteristically localized at the region immediately below or above the plane of valve leaflets (or within 1. The ap pearance of physiological valvular regurgitation in healthy subjects with structurally normal hearts varies with the devices, sensitivity, penetration power and techniques used, with changes in systemic and pulmonary vascular resistance and pressure, and with body habitus and age (3, 6, 7, 9, 12). The prevalence of physiological valvular regurgitation in normal people varied by valve: mitral regurgitation was present in 2. In 25% of patients with acute rheumatic carditis, focal nodules were found on the bodies and tips of the valve leaflets, but the nodules disappeared on follow-up (17). Congestive heart failure in patients with rheumatic carditis appears to be invariably associated with severe mitral and/or aortic valve insuffi ciency (16, 17). Myocardial factor or myocardial dysfunction ap peared not to be the main cause of congestive heart failure, as the percent fractional shortening of the left ventricle in such patients with heart failure has been found to be normal, and they improved rapidly after surgery (16, 17, 19). The pathogenesis of severe mitral regurgita tion has been found to be owing to a combination of valvulitis, mitral annular dilatation and leaflet prolapse, with or without chordal elon gation (16, 17). Chordal rupture occurs in some patients with rheu matic carditis requiring an emergency mitral valve repair (14, 20). Echo-Doppler and colour flow Doppler imaging may also provide supporting evidence for a diagnosis of rheumatic carditis in patients with equivocal murmur, or with polyarthritis and equivocal minor manifestations (10, 17). Classification of the severity of valvular regurgitation using echocardiography Traditionally, the severity of valvular regurgitation has been classified according to a five-point scale (0+, 1+, 2+, 3+ and 4+), based on the echocardiographic findings with angiocardiographic correlations (21– 24). But based on colour flow Doppler mapping, it has been suggested that the severity of mitral and aortic valvular regurgitation may be classified into a six-point scale as follows (21–24): 0: Nil, including physiological or trivial regurgitant jet <1. Diagnosis of rheumatic carditis of insidious onset In patients with rheumatic carditis of insidious onset, or indolent carditis, as defined in the 1992 update of the Jones criteria (25), echocardiography serves to establish the diagnosis of mitral and/or aortic insufficiency, after excluding the non-rheumatic causes, such as congenital mitral valve cleft and/or anomalies, degenerative floppy mitral valve, bicuspid aortic valve; and acquired valvular diseases due to infective endocarditis, systemic disease and others. Silent, but significant, very mild (grade 0+) mitral and/or aortic valvular regurgi tation may be transient or persistent, even for years (26). In cases of indolent rheumatic carditis, the cardiomegaly and valvular regurgita tion may improve, and valve competency may even be restored (26, 27). The use of echocardiography to assess chronic valvular heart disease Two-dimensional echocardiography can display the anatomical pathology of the mitral, aortic, tricuspid and (less well) pulmonary valves, and the valvular annulus and apparatus can be delineated. Colour flow Doppler imaging has gained wide acceptance for qualita tively and quantitatively evaluating the flow characteristics across the valve, as well as for evaluating the severity of the flow pathology (11, 22, 28, 29). Congenital, as well as acquired, valvular disease of non rheumatic origin has to be excluded. Echocardiography may assist physicians to decide the timing of surgical intervention for diseased valves (29). These findings are easily and accurately detected and displayed by echocardiography. Echocardiographic images reveal: (i) a regurgitant jet >1cm in length; (ii) a regurgitant jet in at least two planes; (iii) a mosaic colour jet with a peak velocity >2. Based on the presence of very mild “silent but significant” valvular regurgitation, a new category of “subclinical carditis”, “echocarditis” or “asymptomatic carditis” has been proposed in patients with chorea and polyarthritis (30–35, 37, 41, 42). In such cases of subclinical rheu matic carditis, annular dilatation, leaflet prolapse, and elongation of the anterior mitral chordae were observed, indicating that the valve might have been sensitized or damaged (30, 33). Patients with sub clinical valvular regurgitation may develop an audible murmur in two weeks (31), may continue without audible murmur for 18 months to five years (35–37), or may progress to irreversible sequelae, such as mitral stenosis (35). Although other studies do not support these findings (10, 43, 44), 2D echo-Doppler echocardiography detected trivial-to-mild mitral valvular regurgitation in 38–45% of normal/ healthy children (7, 9, 10), and in even higher proportions of febrile patients (10). These results confirm the usefulness of 2D echo-Doppler and colour flow Doppler echocardiography for diagnosing subclinical rheumatic carditis. However, the use of echocardiography to detect left-side valvular regurgitation and confirm a diagnosis of subclinical rheu matic carditis remains controversial. As such, until the results of long term encompassing prospective studies are available to substantiate the therapeutic and prognostic importance of subclinical rheumatic carditis, the addition of this criterion to the Jones criteria cannot be justified (10, 43–47). However, the acute management of such patients and the duration of secondary prophylaxis would not change significantly, even if a diagnosis of subclinical carditis were made (10, 43, 44). It is also important to recognize that technical expertise with colour flow Doppler echocardiography is necessary to make an accurate diagnosis of subclinical carditis and to avoid overdiagnosis. As a 44 result, the impact of erroneous diagnoses of rheumatic carditis based on subclinical echocardiographic findings should not be underesti mated, nor should the potentially adverse consequences to patients and health systems in such settings (10, 44). Conclusions: the advantages and disadvantages of Doppler echocardiography There are significant advantages in using echocardiography to detect valvulitis. Foremost, is its superior sensitivity in detecting rheumatic carditis, which should prevent patients with carditis from being misclassified as noncarditic and placed on abbreviated secondary pro phylaxis, in line with the more benign prognosis. It is reasonable to accept that valvular regurgitation may not always be detected by routine clinical auscultation. This suggests that carditis was missed by clinical examination, even in the golden era of clinical auscultation. A second advantage of echocardiography is that it should allow the valve structure to be detected, as well as nonrheumatic causes of valvular dysfunction. This could be ascribed either to the high sensitivity of Doppler echocardiography for diagnosing valvular regurgitation, or to the overdiagnosis of physiological valvular regurgitation as an organic dysfunction, or to both. But in many developing countries, it is unreasonable to expect that previous echocardiograms or records will be available for comparison.

The report author speculated that finding a higher injury rate during the nighttime hours could relate to lack of visibility treatment lower back pain buy generic cyklokapron on line, cold temperatures and lower alertness of fire fighters symptoms thyroid cancer purchase 500mg cyklokapron with mastercard. To investigate the latter possibility symptoms to diagnosis buy cyklokapron mastercard, Sobeih and colleagues (2006) studied the effects of working long shifts and wearing turnout gear symptoms in spanish buy 500mg cyklokapron free shipping, including self-contained breathing apparatus symptoms leukemia order cheap cyklokapron line, on fire fighters’ postural stability xerostomia medications side effects buy generic cyklokapron 500mg. They measured strength medications may be administered in which of the following ways trusted cyklokapron 500mg, balance acute treatment purchase cyklokapron with visa, and postural stability with a force plate system at the beginning of the shift and repeatedly over 12 hours among 16 healthy Cincinnati fire fighters. For each assessment, fire fighters changed into their gear and were assessed performing different activities, in their uniforms and when wearing personal protective equipment. Perhaps because of the anchoring effect of their gear, researchers found that postural sway (an indicator of muscle fatigue and/or weakness) decreased when fire fighters wore their personal protective equipment. They reported a trend for decreased postural stability over the 12 hour work shift. One fire fighter was measured over a 48 hour shift, and he showed even greater loss of stability near the end of that shift. Comparison Times of Injuries and Times of Fires * Greater risk of injury * in the early morning From Karter, 2003. The authors felt that their findings indicated that prolonged shifts may contribute to the high prevalence of slips and falls among fire fighters. They also noted that their study was at risk for the “healthy worker effect,” which tends to minimize findings as volunteer subjects often are least likely to be affected by the test conditions. Volunteers must meet physical ability requirements, undergo reference/background checks and complete training requirements. The term volunteer also may be used in reference to part-time or on-call fire fighters who may have other occupations. Although they volunteer to respond, they are compensated as employees when working. Volunteer fire fighters are supported by national organizations, and many resources are available, such as the National Volunteer Fire Council’s Retention and Recruitment Guide for the Volunteer Emergency Services: Challenges and Solutions (2005). Data from the Firefighter Fatality Investigation and Prevention Program compares fatalities among volunteer and career fire fighters (Centers for Disease Control and Prevention, 2006). Although the overall death rates were roughly comparable among career and volunteer fire fighters, their causes of death differed. For both career and volunteer fire fighters, cardiac events were the leading cause of death. However, for volunteers, motor vehicle crashes were the second leading cause of death. In general, volunteers live within a specified distance of the fire department, and they often use their personal vehicles to respond to a fire alarm. The reporting system is limited by only tabulating fatalities; other non-fatal crashes are not indexed. Review of motor vehicle-related fatalities, based on available information concerning circumstances and time of day, revealed only one (in 1999) that appeared clearly fatigue-related. As mentioned, family stress from extended work shifts can be significant, and that factor may be even greater given the unpredictably of volunteer fire fighters’ schedule. This has provided an important source of information concerning health hazards (Centers for Disease Control and Prevention, 2006). While reporting of on duty deaths is complete, the system does not capture nonfatal events. Importantly there is no data on crashes that occur during the commute home following a shift, which may be a vulnerable time for fatigued employees. They stay at a base camp during off duty hours and work at the fire sites for shifts that extend beyond the typical eight hours and involve physical demands well above those of even the most vigorous of other occupations. Work shifts that exceed 16 hours and/or consecutive days that do not meet the 2:1 work/rest ratio should be the exception, and no work shift should exceed 24 hours. After completion of a 14 day assignment and return to the home unit, two mandatory days off should be provided. Crew leaders must allow appropriate rest for their crew and monitor members for signs of fatigue. The crew leaders especially must get enough rest, as long shifts and lack of sleep impair cognitive function more quickly than physical abilities, and they are responsible for organizing the work to minimize crew member fatigue, such as changing assignments to help maintain interest. Studies of energy expenditure during this arduous work indicate that daily energy expenditure approximates that of running a marathon and is more than twice that of recreationally active college students (Heil, 2002; Ruby et al. Because of that physical drain, along with long hours and lack of sleep, researchers have looked for physiological manifestations of work stress, such as depressed immune function. For example, investigators studied wildfire crews by obtaining saliva samples just prior to and immediately after shifts of different lengths, and they found that after working 12 hours, there was a fall in immunoglobulins (disease fighting antibody levels). When fire fighters worked longer than 12 hours, the immune response did not recover by the following day and remained depressed for five additional work days. Based on their findings, the researchers noted the importance of being well rested prior to deployment, obtaining seven to eight hours of sleep each night and using short (less than 20 minutes) or long (more than 90 minute) naps when possible (Childress, 2004). Reviewing the last three years of reported events (2003 to 2006), communication issues were the leading category contributing to reported incidents. Of 494 incidents (2003 to 2006), 38 appeared related to human perceptual errors, including fatigue (Bailey, 2007). Fatigue was a clear contributor in six of the serious accidents, three of which resulted in rollover vehicle crashes. Fatigue when driving can lead to poor judgement, inattention, vehicle wandering and falling asleep at the wheel. Wildland fire fighters often travel to and from worksites in 15 passenger vans, which when loaded with occupants become top heavy and prone to rollovers. The most notable fatigue-related incident was when eight crew members were killed in a traffic accident after spending the previous 11 days fighting a forest fire. Weather was sunny and dry, and the crew had been on the road about three hours when the crew driver attempted to pass a semitrailer on a downhill left-hand curve, in a marked no-passing zone. It is a tool and format to identify and remedy safety concerns of wildland fire fighters. As demands for emergency medical services have accelerated, increases in work load and employee dissatisfaction have resulted in changes in shift structure. With the 12 hour schedule, both at 2 months and at 1 year, employees perceived that they were more productive and felt better, with less family and social disruption from their work. Interestingly, an index of emotional exhaustion decreased immediately after the change, and although other indices remained improved with the reduction in shift duration, the emotional exhaustion dimension returned to baseline after one year (Boudraux et al. Prior to the change when 24 hour staffing still was in effect, most paramedics felt the demands for overtime were excessive, and one-third reported working more than 24 hours without sleep in a single week. The majority felt that 24 hour shifts resulted in a decrement in their abilities, and most (72%) reported that 12 hours was the maximum time that it was safe to take calls at the busiest stations. Working 12 hours per day was associated with a 37 percent increased hazard rate, and 60 hours per week increased injuries 23 percent. Although no complete national count of ground ambulance crashes exists, the number can be approached using the National Highway Traffic Safety Administra tion Fatality Analysis Reporting System. Thus, with those data, unlike vehicle crashes in general, fatigue did not appear to be a major factor in crashes. The Census of Fatal Occupational Injuries is the repository for information on fatal work-related injuries. Review of entries from the last two years revealed 34 deaths, with the majority (21) relating to helicopter and plane crashes. Of the 17 surface vehicle crashes, 5 related to commuting to or from work, but details relating to time of day and fatigue were not reported. A death not listed in that site, which appear related to fatigue and resulted in a policy change, is presented on page 48. Discussions of emergency room staffing patterns generally compare 8 versus 12 hour work lengths, as busy shifts longer than 12 hours are associated with unacceptable fatigue and recognized decrements in performance (Joffe, 2006). The 12 hour threshold for declining performance of critical tasks has been confirmed in other studies of medical personnel (see Section 3). Twelve consecutive hours also is the maximum duration that the Institute of Medicine recommends nurses work during a 24 hour period (Scott et al. Flight regulations require 12 hour shifts for pilots, and both 12 and 24 hour shifts are common staffing patterns for non-pilots in the air medical community. German medical transport helicopter pilots’ physiological profiles were studied during prolonged shifts, necessitated by longer summer daylight hours and more motor vehicle crashes with victims needing air transport. Findings indicated that pilots working longer hours accumulated significant fatigue, and the results led to an enforced eight hour uninterrupted sleep opportunity each day (Samel, Vejvoda & Maass, 2004). Interestingly, the investigators found that 80 percent of 24 hour and 50 percent of 12 hour non-pilot crew members had outside employment (Frakes & Kelly, 2005 & 2007), and of concern, more than half reported having arrived to work within eight hours of leaving their other job. Some did not allow naps, because they felt it might encourage arriving at work fatigued. The investigators could find no decrement in performance with the longer work hours in that short term study, and 18 hour shifts were preferred by the nurses due to lifestyle issues (Thomas et al. As stated in this Section’s outset, there is a paucity of available well done studies, and many of investigations have been done in countries other than the U. The health consequences of long work hours, inadequate sleep and disruption in daily rhythms are discussed in Section 1. For the majority of sleep deprived individuals, the problem develops insidiously, and while they might acknowledge their fatigue, they tend to discount its personal impact and consider it an issue for others, not themselves (Jones et al. The concept of adapting to sleep deprivation or training oneself to require less sleep is a myth. Better understanding of sleep and circadian physiology, plus the interest of researchers (Rosa et al. Examples of the products and services that they offer are presented on pages 69 and 70. In general, methods to minimize and cope with long work hours are divided into categories of employment-related issues and those adaptations that individuals personally can make in their working and non-working lives. Although organized into those domains, in reality, all strategies require collaboration among workers and employers. Topics presented in this Section are organized as they relate to workers, including screening, worker habits outside of work (sleep hygiene and other lifestyle behaviors), stimulant use, family issues and commuting. Job structural issues presented include worker environment, physical activity, naps, work hour structure, behavior-based fatigue management and regulations. Once diagnosed, appropriate management, such as using nighttime continuous positive pressure breathing apparatus or other measures, can correct the day time fatigue (Hartenbaum et al. Components Used to Identify Commercial Motor Vehicle Operators Needing Formal Sleep Studies for Obstructive Sleep Apnea 1. Observed unexplained excessive daytime sleepiness or confessed excessive sleepiness. Motor vehicle accident (run off road, at fault, rear-end collision) likely related to sleepiness. Two or more of the following (1) body mass index > 35 kg/m2 ; (2) neck circumference > 17 inches in men and 16 inches in women; (3) hypertension (new or uncontrolled). Epworth sleepiness scale score > 10, no driving until assessed if Epworth sleepiness scale score > 16 (see page 6 for Epworth scale). Previously diagnosed sleep disorder but no recent medical visits or compliance data available for immediate review. Studies indicate that after a single night of work, approximately half of adults can perform at acceptable levels. One third have a moderate amount of impairment, and the remaining individuals will have moderate to marked decrement in performance (Dinges, 1992). Even the same individual’s ability to tolerate night work may vary over time, unassociated with any identifiable factor. An area of current research, which has not yet reached practical applications, is the recognition of individual variability in the effects of sleep deprivation (Lammers-van der Holst et al. Van Dongen and colleagues (2004) have identified trait-like differences in susceptibility to fatigue and performance decrements due to sleep deprivation, with up to six-fold differences in how individuals responded to the same amount of sleep loss, when controlling for other factors. The researchers concluded that “neurobehavioral deficits from sleep loss constitute a differential vulnerability trait. However, investigation of other unique workers, such as active duty F-117 pilots, revealed that they were not all equally able to tolerate sleep deprivation and demonstrated significant variability in their susceptibility to impairment from sleep loss (Van Dongen et al. Future work may identify individuals more suited for shift work and allow stratifying coping strategies based on a worker’s innate predisposition toward problems from sleep deprivation and circadian disruption. Early Bird or Night Owl Preference work and work long hours diminishes Answer 1=never, 3=sometimes or 5=always, with aging (Reid & Dawson, 2001), and and total your score. Shift naturally are early risers, are most productive during work may be a risk factor for a number of the first half of your day and often fade beginning health harming effects (Section 1). Nights are not off limits, but you don’t healthy lifestyle and achieving the often stay out late. Healthy People 2010 objectives is 22-26 Hummingbird: Flexible and tend to be ready for action especially important (Table 5. In general, adverse effects of irregular shift schedules and long work hours are minimized when people establish some regularity in their bedtime and waking schedule, even on weekends, so that an anchor of fixed sleeping times is maintained. As described in Section 1, all sleep hours are not equal, daytime sleeping is more difficult, and those hours are not as restorative as nighttime sleeping. Shift workers who are up during the night are encouraged to develop good sleep hygiene practices to facilitate falling asleep during the day, after their work ends Healthy People 2010 is a early in the morning. Breakfast foods such as toast, bagels or tives designed to identify the cereal are recommended. Caffeinated and alcoholic beverages most significant preventable should not be consumed before going to bed.

Do not smoke include acoustical and light insulation with eye masks, ear plugs and room darkening shades or drapes; the telephone should not ring into the bedroom during the daytime. During hot weather, a window air conditioner can be used to provide background noise, as well as maintain a cool temperature recommended for sleeping. Shift workers may need to explain to friends and family the importance of restorative sleep and enlist their support. Cooperative neighbors who are aware that there is a night worker sleeping can avoid engaging in noisy activities outside the worker’s bedroom. Sometimes people use night work to allow them to work a second job or provide care for their children during the Table 5. However, the resulting chronic sleep deprivation may No-Doz (max strength) 200 mg increase their risk for accidents and cause mental and Brewed coffee 135 mg physical problems. Individuals may choose to use caffeine or other Coke Classic 35 mg stimulants to maintain alertness either on or off work. Green tea 30 mg Caffeine has a duration of action of three to five hours, but Hot cocoa 15 mg effects can last up to 10 hours in sensitive individuals. Thus, although a limited amount of caffeinated beverages (two to three cups of coffee) during the first half of the night shift enhances alertness, caffeine consumed during the last half of the shift may interfere with falling asleep after the worker gets home. The ‘dose’ of caffeine needed to improve alertness is approximately 250 mg (two cups of average strength Caffeine and modafinil are two of a number brewed coffee), and higher doses are not more of countermeasures or chronobiotic beneficial and increase side effects (van Duinen, interventions, along with light exposure and Lorist & Zijdewind, 2005). Comparison of caffeine melatonin, used to reset or counteract the in different products is shown in Table 5. Most studies of these drugs Recently prescription medications have been and other measures are with simulations of developed to reverse the sleepiness associated with night shift work. Food and Drug Administration for disruption of sleep schedules and allow for treatment of the extreme sleepiness of individuals adequate restorative sleep (Basner, 2005). When studied, use of the drug reduced sleepiness and produced a small but significant improvement in performance (Czeisler et al. However, it is important not to take that finding as meaning that the drug would be useful for all individuals performing shift work. Thus, the results are not applicable for the majority of shift workers, and in that small subset of workers who took the drug, although their performance was improved, it did not reach a normal level. More recent work assessed use of modafinil with emergency room physicians working 24 hour shifts. Investigators found that while the agent increased certain aspects of measured alertness, it also made it more difficult for participants to fall asleep when opportunities for sleep arose (Gill et al. Overall, for the average worker, the effects of modafinil are relatively modest and comparable to those of repeated low doses of caffeine (Dagan & Doljansky, 2006). Involving workers’ families in any job reform is increasingly recognized as important. Wilson and colleagues examined the effects of involving families by using the natural experiment of worksites that did and did not include families in shift work strategy discussions. They found that shift work reform focusing on physiological issues only, without family involvement, was counterproductive and increased family conflict (Wilson et al. Involvement of families can encompass education about the effects of shift work and information about effective countermeasures. Organizing support groups for the workers and their families also can provide a mechanism for recognizing ongoing work-related problems and providing solutions to remedy them. When the causes for motor vehicle crashes were reviewed, drivers at high risk for sleep-related crashes included 1) younger drivers lacking sleep due to demands of school and jobs, late socializing and poor sleep habits; 2) shift workers; 3) drivers using alcohol or other drugs and 4) those with sleep disorders. Simulation studies have confirmed that workers’ driving is impaired after working night shifts. Ten night shift workers were studied using a driving simulator, and researchers compared performance after their typical night shift and following a normal night’s sleep. After their night shift, workers demonstrated almost three times as many wheels outside the lines and more than twice the lateral deviations (Akerstedt et al. Confirming the simulator findings, study of medical interns found that driving home from long work shifts more than doubled the risk of crashes (Barger et al.

We consider the problem of trace contamination being introduced accidentally during the production of ruminants feedstuffs containing constituents of animal origin. The future of animal meal is discussed together with alternatives for disposing of animal carcasses and slaughtery offal, i. The causative agent is the prion, which is still being researched and is controversial. In the 1980s, bovine spongiform encephalopathy brought much media attention to these diseases. Bovine spongiform encephalopathy is the result of faulty industrial practices that produced cattle feed contaminated by prions. This article describes the history, causative agent, mode of transmission, clinical features and course, diagnosis, treatment, and decontamination and sterilization guidelines for this baffling disease. Transmissible and genetic prion diseases share a common pathway of neurodegeneration. Together, these data suggest that the events of CtmPrP-mediated neurodegeneration may represent a common step in the pathogenesis of genetic and infectious prion diseases. The number of cases is declining, with fourteen cases diagnosed in 1998 (at 29 December 1998). However, the potential weakness in current activities that allow the disease to exist are being evaluated. Further measures to avoid even minimal risk for human and animal health will be taken if required. Experience gained from the past indicates that it is necessary to review the situation constantly and to inform the public and professionals regularly and in a transparent manner. Abstract: In this article we review the concept and terminology of prions, their replication and some current hypothesis on the nature of these infectious agents causing neurodegenerative diseases. This revision also summarizes the etiopathogenic, epidemiological, clinical and neuropathological features of the prion diseases or human transmissible spongiform encephalopathies, and some methods for their early diagnosis. Finally, we discuss the possible link between the bovine spongiform encephalopathy and the new cases of Creutzfeldt-Jakob disease identified in the United Kingdom. Mad Cow and Related Diseases: Challenges for Waste Management Remediation 1999 vol. This report updates these data, analyses the risk by using data to 1997, and predicts potential risk into the next decade. From this, the calculated risk of a prion-infected corneal donor appearing in the donor pool is 0. Whereas donors completely without any neurologic symptoms cannot be screened by using any currently available laboratory method, those with a characteristic quadrate clinical prodrome including cognitive changes, speech abnormalities, cerebellar findings, and myoclonus could all be potentially excluded by using tightened medical record and historical screening criteria. Tightening of exclusionary queries would significantly reduce the risk of even this number of patients appearing for corneal donation. Clearly, the benefits of corneal transplantation in the overall population continue significantly to outweigh the risks of transmission of prion disease.

S63 J66 1999 Descriptors: bovine spongiform encephalopathy, Creutzfeldt-Jakob disease. S39-S41 Abstract: There is a continuous change in viral epidemics with respect to clinical symptoms, their duration or disappearance and the emergence of new diseases. This evolution of virus diseases is mainly related to three factors: etiological agent, host and environment. As far as genetic alterations of the virus are concerned, two major mechanisms are involved: 1) mutations such as recombination and reassortment; 2) selection for resistance or susceptibility. The responsible agent is unconventional and appears to be largely composed of a glycoprotein, the prion protein PrP. In prion diseases, it becomes converted to the pathogenic form PrPres which is resistant to proteinase and accumulates within the brain and this process is accompanied by the development of spongiform change, gliosis and neuronal loss. The human prion diseases include Kuru a progressive cerebellar degeneration with late dementia affecting Fore tribes in New-Guinea, now almost extinct, regarded as being related to cannibalism. Four variants are now recognized: sporadic, familial, iatrogenic and the new variant. It is now widely accepted that it is due to the same agent responsible for Bovine Spongiform Encephalopathy in cattle. The main neuropathological change is neuronal loss in the thalamus with little or no spongiosis and usually no PrPres deposition.

Subakutni spongiformni encefalopatie lidi a zvirat (neuralni "antropo a zooprionozy"). Subacute spongiform encephalopathies in humans and animals (neural "anthropo and zooprionoses")]. Abstract: General review concerning current problems of subacute spongiform encephalopathies (Prion-diseases) in humans and in animals. The work is based on the aetiological conception of "Prion" as an allosteric conformational variant of the Prion-protein with autocatalytic "infectious" properties. The therm "Anthropoprionosis" and "Zooprionosis" are recommended by the author for human and animal Prion-diseases. Actual medical problems of various Prion-diseases are discussed in more detail, particularly those of aetiopathogenesis, genetics and molecular-biological principles in Prion-replication as well as the consensual neuropathological and clinical diagnostical criteria. Descriptors: prion diseases, humans, animals, prion replication, neuropathology, public health risks. A number of prion strains can be distinguished by "glycotyping" analysis of the respective deposited PrP(Sc) compound. Differences were found in the long-term proteinase K resistance (50 microg/ml at 37 degrees C) of PrP(Sc). With the exception of strain 87V, PrP(Sc) was generally deposited in the cerebrum, cerebellum, and brain stem of different mouse lines at comparable levels. Long-term proteinase resistance, molecular mass, and the analysis of PrP(Sc) deposition therefore provide useful criteria in discriminating prion strains and isolates.

Development of an integrated procedure for the detection of central nervous tissue in meat products using cholesterol and neuron specific enolase as markers. Des Moines, Iowa : International Association of Milk, Food and Environmental Sanitarians. Sensitivity was increased after reduction of fat content (30 to 40%) of the samples by means of a soxhlet extraction. Immunoreaction was not found to be bound to morphologically intact histological or cytological structures; however, it proved to be highly specific. Cholesterol content increased by 26 mg per 100 g of fresh substance for each percentage of brain added to internally produced reference material. Using three different approaches (internal reference material, raw material, and field samples), a provisional cutoff point of normal cholesterol content was calculated for emulsion-type cooked sausages to be 115 mg/100 g (P < 0.

Pathogenesis of the oral route of infection of mice with scrapie and bovine spongiform encephalopathy agents. PrPres was used as a marker of infectivity and was searched for sequentially in 22 organs during the whole incubation period and clinical stage. This observation may have implications for the horizontal transmission of scrapie in endemically affected sheep flocks. Chicken Prion Tandem Repeats Form a Stable, Protease-Resistant Domain Biochemistry (Washington)1999 vol. Abstract: the prion/amyloid neuropeptide 106-126 spontaneously aggregates to form fibrillar structures in vitro. The aggregation in vitro could be prevented in a dose-related manner by clusterin, and the specificity of this action was confirmed by reversal with antibody to clusterin. In native tissue preparations, little difference was found between the two groups. PrP(Sc) was identified by Western blot, centrifugation, and protease digestion experiments. It was thought that folding or complexing of PrP(Sc) is most probably reversed by the Gh treatment, making hidden antigenic sites accessible. While the concentration of PrP(C) in cattle is similar to that in hamsters, PrP(Sc) sparse in comparison. The detection of PrP(Sc) by a simple physicochemical treatment without the need for protease digestion, as described in this study, could be applied to develop a diagnostic assay to screen large numbers of samples. The communal lesions are neuronal loss, spongiosis and gliosis and, inconstantly, the presence of amyloid plaques and different kinds of small deposits immunolabeled with anti-prion (PrP) antibodies. Recent works have shown the role of the host genotype, especially of codon 129, in the susceptibility to these diseases. We have tried to correlate neuropathology with the genotype of codon 129 and the type of PrP to establish a molecular classification. A central contention is that an explicit focus on definition illuminates the processes by which scientific judgements are made, promoted, communicated, assessed and judged and gives an improved picture of policy making. Neglected areas such as the role of secrecy, public relations and the mass media in the science-policy interface are brought into sharper focus as an intrinsic part of the wider operation of definitional struggles. The focus on definitional struggles also sheds light on some current work on risk in social theory. It is argued that the neglect of questions of agency which are central to definitional struggles has led to some theorists presenting risks as inevitable concomitants of technological and cultural developments leaving them in the grip of political quietism. Main outcome measure: Dietary habits assessed by a semi-quantitative food frequency questionnaire. While chicken intake increased (+44 g/month, -2 to 88), overall intake of meat (including poultry but not fish) declined by 204 g/month (or 2. In men the decrease in beef intake was not statistically significant (-48 g/month, -172 to 80), but consumption of chicken increased (++56 g/month, +8 to +104).

The threat posed by the global emergence of livestock, food-borne, and zoonotic pathogens. Dealing with unexpected or unknown emergencies: examples of Australian approaches. Abstract: Emergencies may derive from unknown agents or an unusual incident from a known exotic or endemic disease agent. Veterinary administrations must be able to deal rapidly with these occurrences, to allay public fears, media interpretations, and environmental or political concerns. The emergency approach to deal with such incidents should be based on well-established disease control principles. In dealing with the unknown, veterinary authorities must take a comprehensive approach to managing the problem. Events such as the bovine spongiform encephalopathy in the United Kingdom and Europe have shown that management becomes much more complex when animal health events also involve human disease. The absence of scientific knowledge creates an environment of speculation, fear and mistrust, which may seriously erode the ability of animal health authorities to respond as they would wish. An established structure which identifies the roles and responsibilities of key players and clearly states where accountability for handling the situation ultimately rests is essential. In addition, emergency plans which have been tested by training exercises, for example, are critical. Other operators who could be involved in the management of emergencies must also be fully aware of their roles in the event of a problem. Over recent years, Australia has experienced a number of new diseases which have had to be handled in an environment of uncertainty and in conditions where knowledge was lacking. The authors briefly outline a number of these incidents as case studies and list the key factors involved in dealing with each emergency. PrP genotypes of captive and free-ranging Rocking Mountain elk (Cervus elaphus nelsoni) with chronic wasting disease. Sequence analysis of the PrP gene from Rocky Mountain elk showed only one amino acid change (Met to Leu at cervid codon 132).

Protection of personnel and environment against Creutzfeldt-Jakob disease in pathology laboratories. Neuropathologists have been long aware of the transmissibility and unique properties of the agent which make it resistant to conventional inactivating reagents. It gives practical advice and a key to more detailed procedures, guidelines and recommendations available in scientific literature and through government agencies. It is believed to have led to a new form of spongiform encephalopathy in humans and as yet there is no way of knowing how many people will die of this disease. Here we review some examples of where this has happened, sometimes with a beneficial outcome and sometimes with a misleading outcome. But, we argue, the evidence for maternal transmission of scrapie, collected in the 1960s, was based on small numbers and is inadequate. Subsequent research has shown a very substantial genetic component in scrapie and epidemiological data show no excess risk in the offspring of affected ewes relative to the risk in the offspring of affected rams.

Classification keys were used to identify descriptive, analytical and theoretical epidemiological studies used to formulate etiologic hypotheses, to assess the relevance of several risk factors and to monitor and predict the future of the epidemic. Case series, incidence and ecological studies, case-control studies, a cohort study and modelling epidemiology studies have been considered. Today, the proposed hypotheses are these cases are due to: occurrence of sporadic cases without identifiable cause; cross-contamination between feeds for monogastric animals containing animal products and compound feed for polygastric animals without meals of animal origin, during the manufacturing process, the storage or distribution; use of animal meals in the compound feed for bovines before the ban (27/7/1994). Retrospective study of the incidence of notified and suspected bovine spongiform encephalopathy neurological cases in Belgium. Use of capillary electrophoresis and fluorescent labeled peptides to detect the abnormal prion protein in the blood of animals that are infected with a transmissible spongiform encephalopathy. Abstract: Transmissible spongiform encephalopathies in humans and in animals are fatal neuro-degenerative diseases with long incubation times. The putative cause of these diseases is a normal host protein, the prion protein, that becomes altered.
