Explain: Who was the most important influence on you and why? Inheritance patterns include the following: Autosomal Dominant Disorders caused by one mutated copy of a gene. Autosomal dominant disorders usually occur in every generation of an affected family. When a person carries an autosomal dominant gene mutation, each of his/her offspring has a 50% chance for inheriting the gene mutation. An affected person usually has unaffected parents who each carry one copy of the mutated gene. Autosomal recessive disorders are not usually seen in every generation of a family. X-linked dominant Disorders caused by mutations in genes located on the X chromosome. Females are more frequently affected than males, and the chance to pass on an X-linked dominant disorder differs between men and women. Females who have an X-linked dominant gene mutation have a 50% chance to have an affected child. Males are more often affected than females, and the chance to pass on the disorder differs between men and women. Families with X- linked recessive disorders often have affected males, but rarely affected females, in each generation. Females who carry an X-linked recessive gene mutation have a 50% chance to pass it on to each of her children. Multifactorial Disorders caused by a combination of the effects of multiple genes or by interactions between genes and the environment. Hereditary breast/ovarian cancer is inherited in families in an autosomal dominant pattern. Congenital heart disease - Congenital heart disease is a common type of birth defect or malformation in one or more structures of the heart or blood vessels that occurs during pregnancy while the fetus is developing. There are some recognized factors that are associated with an increased risk for congenital heart disease including: 1) genetic or chromosomal abnormalities such as Down syndrome; 2) taking certain medications, alcohol or drug abuse during pregnancy; and 3) maternal viral infections such as German measles in the first trimester of pregnancy. The risk of having a child with congenital heart disease is higher if a parent or a sibling has a congenital heart defect. Sickle cell anemia - Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. Individuals who have sickle cell disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape. Signs and symptoms include a low number of red blood cells (anemia), repeated infections, and periodic episodes of pain. Each child of carrier parents has a 25% chance to be born with sickle cell anemia. Factor V Leiden is the name of a specific mutation that results in thrombophilia - the increased tendency to form abnormal blood clots in blood vessels. People who have the factor V Leiden mutation are at somewhat higher than average risk for a type of clot that forms in veins, such as the deep veins of the legs (deep venous thrombosis), or a clot that travels through the bloodstream and lodges in the lungs (pulmonary embolism). Factor V Leiden thrombophilia can be inherited in families in an autosomal dominant and autosomal recessive manner. People who have hemophilia often experience prolonged bleeding or oozing following an injury, surgery, or having a tooth pulled. The major types of this condition are hemophilia A (also known as classic hemophilia) and hemophilia B (also known as Christmas disease). In X-linked recessive inheritance, a female with one altered copy of the gene in each cell is called a carrier. She can pass on the altered gene to her children, but usually does not experience signs and symptoms of the disorder? Tay-Sachs - Tay-Sachs disease is a rare inherited disorder that causes progressive destruction of nerve cells in central nervous system (the brain and spinal cord). Affected infants progressively lose motor skills such as turning over, sitting, and crawling. Children who have the severe infantile form of Tay-Sachs disease usually survive only into early childhood. Symptoms of beta thalassemia occur when not enough oxygen gets to various parts of the body due to low levels of hemoglobin and a shortage of red blood cells. Alpha-1 antitrypsin disorder - Alpha-1 antitrypsin deficiency is an inherited condition that can cause lung disease in adults and liver disease in adults and children. Co-dominance means that two different versions of the gene may be expressed, and both versions contribute to the genetic trait. Cystic Fibrosis - Cystic fibrosis is an inherited disorder of the mucus glands that affects many body systems. The most common signs and symptoms of cystic fibrosis include progressive damage to the respiratory system and chronic digestive system problems. When an infant has pyloric stenosis, the muscles in the pylorus become enlarged to the point where food is prevented from emptying out of the stomach. When a parent has pyloric stenosis, then, their infant has an increased risk of developing the disorder. Examples of types of dwarfism include: achondroplasia, thanatophoric dysplasia, and Robinow syndrome. Polycystic kidney disease - Polycystic kidney disease is a disorder that affects the kidneys and other organs. Cysts, develop in the kidneys, causing them to become enlarged and can lead to kidney failure. There are two major forms of polycystic kidney disease distinguished by the age of onset and their pattern of inheritance. Instead of opening at the tip of the penis, a hypospadic urethra opens anywhere along the line running from the tip along the underside of the shaft to the where the penis and scrotum meet. In some cases, hypospadias happens as a result of a chromosomal abnormality called a pericentric inversion of chromosome number 16. The causes of miscarriages are varied, and most often the cause cannot be identified. In some cases the chromosome abnormality in the developing fetus is the result of a parent carrying a balanced chromosomal arrangement called a translocation. Causes of birth defects include a family history of birth defects, maternal age, certain drugs taken during pregnancy, alcohol use and smoking during pregnancy. Mental Retardation - Mental retardation is a term used to describe a person who has certain limitations in mental functioning and difficulties in communicating, taking care of him or herself, and social skills. These limitations will cause a child to learn and develop more slowly than a typical child. Causes of mental retardation include genetic conditions such as Down syndrome, problems during pregnancy, problems at birth and health problems such as malnutrition. Cerebral palsy is caused by injuries to the largest part of the brain (cerebrum) which happen as the baby grows in the womb or near the time of birth. There are multiple causes of cerebral palsy including birth defects that affect the brain, spinal cord, head, face, lungs or metabolism, and certain hereditary and genetic conditions. Neurofibromatosis type 1 is a disorder characterized by changes in skin coloring (pigmentation) and the growth of tumors along nerves in the skin, brain, and other parts of the body. Neurofibromatosis type 1 is considered to have an autosomal dominant pattern of inheritance. Neurofibromatosis type 2 is a disorder characterized by the growth of noncancerous tumors in the nervous system. Neurofibromatosis type 2 is also considered to have an autosomal dominant pattern of inheritance. The genetics of autism are complex and it is thought that there are multiple genes involved. Children who have Aspergers syndrome do not usually have language or cognitive developmental delays. Genes are believed to play a role in Aspergers syndrome, and it seems to run in some families. The excessive accumulation of fluid causes an abnormal widening of spaces in the brain called ventricles. Hydrocephalus may be caused by inherited genetic abnormalities (such as the genetic defect that causes aqueductal stenosis) or developmental disorders (such as those associated with neural tube defects including spina bifida and encephalocele). Other possible causes include complications of premature birth, and diseases such as tumors or hemorrhage which block the fluid. These tumors can occur in the skin, brain, kidneys, and other organs, in some cases leading to significant medical problems. Tuberous sclerosis is inherited in an autosomal dominant manner, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In about one-third of families, an affected person inherits an altered gene from a parent who has the disorder. These cases occur in people with no history of tuberous sclerosis in their family. Prion diseases are group of progressive conditions that affect the nervous system. Prion diseases impair brain function, causing memory changes, personality changes, a decline in intellectual function, and problems with movement that worsen over time. The signs and symptoms of these conditions usually begin in adulthood, and these disorders lead to death within a few months to several years. Creutzfeldt-Jakob disease is acquired by eating beef products obtained from cattle that have prion disease. An early-onset, less common form of Huntington disease begins in childhood or adolescence. This condition is inherited in an autosomal dominant manner, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Major signs and symptoms of Type 1 Gaucher disease include enlargement of the liver and spleen, a low number of red blood cells, easy bruising caused by a decrease in blood platelets, lung disease, and bone abnormalities such as bone pain, fractures, and arthritis. Types 2 and 3 Gaucher disease, on the other hand, have problems that affect the central nervous system. Gaucher disease is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents each carry one copy of the mutated gene, but they do not show signs or symptoms of the disease. Typically, signs and symptoms of Wilson disease first appear during the teenage years. Wilson?s disease is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents each carry one copy of the mutated gene, but they do not show signs or symptoms of the disease. In most cases, tics become milder and less frequent in late adolescence and adulthood. A variety of genetic and environmental factors appear to play a role in causing Tourette syndrome. Among family members of an affected person, it is therefore difficult to predict who else may be at risk of developing the condition. Depression Clinical depression is an illness that can challenge a person?s ability to perform even routine daily activities, and in some cases lead a person to contemplate or commit suicide.

bentyl 20 mg sale

The July 2011 proposal was an attempt to deal with free riding only through the last mechanism gastritis diet natural remedies buy 20 mg bentyl amex, by offering an upgrade from Greek law to English law combined with collateralized principal xylitol gastritis purchase 20 mg bentyl overnight delivery. By January 2012 gastritis quimica 20 mg bentyl with visa, however gastritis symptoms images generic bentyl 20mg with mastercard, it became clear that there was a problem with this approach: offering a combination of cash incentives and a safer instrument would not gastritis diet лего purchase genuine bentyl line, by itself gastritis diet xyngular buy cheap bentyl 20 mg line, address the free rider incentive for creditors holding sufficiently short-term bonds. Conditional on a successful voluntary exchange, short-term bondholders are very likely to be repaid in full even if the claim is junior to the new debt, as the chance of a new debt crisis in the (short) period between the exchange and the maturity date is very low. The end result was that Greece relied on all three of the above mechanisms, although with different emphasis, and in new ways: First, and most importantly, it introduced a powerful collective action mechanism into domestic law bonds. In February 2012, the Greek parliament enacted the Greek Bondholder Act, which allowed it to impose the new payment terms on holdouts with the agreement of two-thirds of face value weighted votes. Unlike the English-law bonds, this threshold applied across bonds rather than just bond-by bond, subject only to a participation quorum of at least 50 percent of face value. In the end, this aggregation feature turned out to be pivotal for the results of the debt exchange, as it allowed the restructuring of 100 percent of the Greek-law sovereign bonds, which themselves made up over 86 percent of the bonds covered by the restructuring. Second, the bundle of new securities was designed to be as attractive as possible, for a given haircut, to bondholders who feared (correctly) that Greek sovereign risk would remain high even after a successful debt exchange. These notes turned out to be by far the most valuable component of the securities bundle offered to creditors, representing almost two-thirds of its value (15 out of 23; see Table 3). Regardless of what happened to Greece, participating investors would have this ?bird in hand?. However, the contract provisions were arguably less important than the governing law itself. According to data by Cruces and Trebesch (2013), the average cash sweetener across 180 debt restructurings since 1975 amounted to only 3. Finally, although the Greek government went out of its way to appear non-coercive before and during the exchange offer?for example, the February 24 invitation refers to the exchange as a ?voluntary liability management transaction by way of a voluntary bond exchange?it did, at the last minute, adopt a harsher tone towards potential holdouts. Although it is impossible to say exactly how much either the upgrade in ?safety? or fear of discrimination contributed to the success of the exchange offer, it is clear that the safety upgrade was viewed as essential ex ante and that one or both played a significant role ex post. Even a solid commitment by members of the creditor committee would not have been enough to ensure that the two-thirds majority threshold specified by the Greek Bondholder Act would be met. With hindsight, we know that over 82 percent of Greek law bondholders exchanged their bonds and an additional 3. Thus, there must have been a significant contingent of potential free riders (perhaps 20 to 30 percent 41 Even so, an analysis of Greece?s behaviour using an index of government coerciveness developed by Enderlein et al. From Debt Exchange to Buyback Despite the success of the debt exchange and the associated approval of a second official bailout program for Greece on March 14, 2012, high yields on the new bonds signaled the market?s view that a second default in Greece continued to be a clear and imminent danger. Part of this had to do with domestic political and social opposition to the adjustment program, which materialized in the general elections in May with the unexpected rise of the left-wing Syriza party. The ensuing political deadlock receded only after a second election in June enabled a pro-bailout coalition government under a new Prime Minister, Antonis Samaras (Figure 6). Yields of new Greek sovereign bonds from issue date until buyback Source: Bloomberg However, continued high default risk also had to do with the design of the March debt exchange and the associated second bailout program itself. Greece had received a high degree of debt relief, but only at the price of promising more austerity and structural reform which?given its economic and social troubles?did not seem plausible to many outside observers. At the same time, debt service after the exchange continued to be surprisingly high in the short term. At the same time disproportionately high haircuts discouraged particularly short term bondholders from taking part in the exchange. In the event, program payments were delayed, as the program ran off track almost immediately as result of the May and June elections and protracted negotiations with the new government. Greece coped by continuing to cut spending, accumulating arrears on other government liabilities and selling T-bills to its banks. At the same time, the economic news was not encouraging, especially with respect to growth. At the same time, euro area leaders balked at the idea of large scale debt relief so soon after large scale official lending had been made available to Greece at terms that were already significantly more favorable than the first package. There was particular resistance against politically highly visible cuts in the face value of debt owed by Greece. The most controversial element of the November package, and the only one involving private creditors, was the proposed buyback of Greek sovereign bonds issued only nine months earlier. From the perspective euro area leaders, the appeal of this proposal was that it allowed a face value reduction of Greek debt without requiring an unpopular nominal write down on the official debt. At the same time, the average price at which Greece had bought back its debt, 34 cents per euro of face value, had increased by over 20 percent since the buyback was announced in late November. This seemed to confirm a problem with voluntary buybacks that economists had been pointing out for some time, triggered by the 47 experience of the Bolivian buyback of 1988: namely, that their benefits tend to be appropriated by the creditors, in the form of a higher market value of debt, rather than by the debtor country. The question is to what extent this is true for the case of Greece, and whether and to what extent Greece improved its debt sustainability as a result of the buyback. To answer these questions, it is necessary to briefly recall the essence of the ?buyback boondoggle? argument?that is, the claim that voluntary debt buybacks are generally a 48 waste of public funds. The average buyback price will therefore be generally higher than the initial price of the debt. If debtors expect the debt to decline as a result of the buyback, they will no longer be willing to sell at the initial price, because this no longer reflects the true value of the debt. As a result, ?negotiated buybacks?, which cap the extent of the price rise (or try to lock in the pre-announcement price), are always preferable to voluntary buybacks, at least from the perspective of debt reduction. Note, however, that the extent to which the price actually rises in a voluntary buyback will depend on the circumstances. In both cases, the expected net reduction in the face value of debt service obligations will tend to push the price up. This means that the buyback price will rise less compared to the pre-buyback price (it is even possible to construct examples where it would fall). For example, the buyback critics of the late 1980s would feel that a situation in which the market value of the debt is unchanged after the buyback?because the reduction in face value is offset by an increase in the price of the debt, as happened in Bolivia?is clear waste of public money. Implicit in this view is the assumption that debt repayment involves a zero-sum game between a debtor country and external creditors in which the value of the 50 debt reflects the expected resource flow from debtors to creditors. However, this may not be true in situation in which a default has large domestic costs, or involves a deadweight loss. In such cases, a buyback that helps the country avoid default may well be welfare improving even when it leaves the market value of the debt unchanged (indeed, even if it increases the market value of the debt). In the case of Greece, which had large domestic creditors and undertook the buyback in the context of a broader deal with its official creditors, it is almost surely wrong to use the change in the market value of its net assets as the yardstick for whether the buyback should be considered a success. Nonetheless, since the literature used this yardstick for other famous cases, it is interesting to see how the Greek exchange would fare by comparison. That is, in these papers, all costs arising to the country from either debt repayment or default involve a corresponding gain to creditors, and vice versa. October (just before Asmussen?s remarks became public); this would generate an upper bound on the price change that may have been driven by the buyback. Hence, the market value of Greece?s net asset position would have improved by ?7 - ?2. In this case, the initial market value of the debt that was bought back would be much smaller, namely just ?13. If it is discounted at a sufficiently lower discount rate than the market yield of 11. Using the November 23 reference price, that threshold discount rate would be about 6 percent; using the October 11 reference price, it would be 10 percent. But the point here is merely that based on a market value yardstick, it is not possible to condemn 51 the Eurogroup statement of November 27, 2012 itself seems to view the price November 23 as the relevant pre- buyback reference: ?The Eurogroup was informed that Greece is considering certain debt reduction measures in the near future, which may involve public debt tender purchases of the various categories of sovereign obligations. If this is the route chosen, any tender or exchange prices are expected to be no higher than those at the close on Friday, 23 November 2012. We next move to the question whether the buyback achieved debt relief that made it easier for Greece to repay its remaining debt in full. Given that this was the stated purpose of the buyback, this strikes us as the key issue. To answer this question, we compute the impact of the buyback on the Greek debt burden use the same discount rates as in the previous section?3. The main result, given in the bottom two rows of Table 5, is that in addition to a face value reduction of ?20. These are not very large amounts, but respectable, given Greece?s dire 53 situation and the limited scale of the operation. There is no reason why the buyback, even if it was not fully voluntary, would have inflicted a loss on Greek banks. In the next section, we show some counterfactual calculations that illustrate this point. Figure 7: Change in composition of Greek sovereign debt T-Bills; 15 T-Bills; Holdouts 23. Figure 7 shows the overall effect of the Greek restructuring on Greece?s creditor structure. In less than a year, the structure of Greek government debt was turned upside down, with privately held debt (bonds and T-Bills) now accounting for only about 20 percent of total. In mid-February 2012, banks and other investors still held almost ?206 billion of Greek bonds. But after the March/April exchange and the subsequent buyback this selling it for 34 cents/?. In accounting terms, banks were either marking their holdings to market, in which case the buyback made no difference or were holding them to maturity, in which case the would have been valued at the initial 25 cents/? price, in which case banks realised a profit. At the same time, official loans by other euro area governments increased from ?58 billion in early 2012 to more than ?160 in late 2012, with a further ?35 billion committed for 2013. We are not aware of any other similarly drastic case of ?credit migration? from private into official hands in the history of sovereign debt. Finally, what was the combined effect of the debt exchange and buyback on Greece?s creditors? A creditor participating in both would have received 15 cents in quasi-cash and 31. We conclude that participating investors lost about 65 percent of the value of their claims on average as a result of both restructuring operations, with wide difference between holders of short maturities, who lost up to 74 percent, and of longer maturities, who lost far less, as indicated in Figure 5. Assessment and Outlook For students of debt restructurings, there were many aspects of the Greek restructuring that were, to use the technical term, cool. The Greek deal also hit firsts (or near firsts) in terms of the use of aggregation provisions, the attempt to link repayments of new bonds and repayments to a multilateral, and in giving official creditors a veto over changes in bond payment terms or new debt issues beyond a specified maximum. For the people of Greece and Europe, however, it is not legal and financial pyrotechnics that count, but what the restructuring ultimately delivered. Could Greece (and/or its official creditors and the taxpayers they represent) have gotten a better deal? Will the restructuring make future debt restructuring in Europe easier or more difficult? And to what it extent does Greece?s restructuring provide a template for other euro area countries seeking to restructure their debts? Economic theory answers the question of when it is optimal for countries to default roughly the same as common sense would. In the presence of default costs?financial disruptions and output costs?defaults should be rare events, but can be desirable when countries face high debt and large solvency shocks (see Adam and Grill (2012) and references therein). The presence of collateral damage on other countries?contagion? changes the interpretation of default costs, but does not change the answer; except for one key complication: it implies that there may be a second instrument?transfers across 35 countries?as an alternative to default. This may help ex post, but creates a moral hazard problem ex ante, since debtor countries have control over their debt levels, the contracts they enter into, and ultimately, their resilience to shocks. Deciding whether the Greek restructuring was the right decision hence involves two questions. First, had Greece reached the threshold level of distress and high debt which would justify a debt restructuring purely from a domestic standpoint, abstracting from contagion? Second in light of the collateral damage that the Greek restructuring was likely to inflict on other countries?and arguably did?was there a better alternative? In his baseline scenario the Greek debt ratio would peak at 175 percent in 2012 and then fall to 113 percent by 2020. With hindsight, these assumptions do not seem plausible, particularly for a country with a weak fiscal track record. This leads to the second question: accepting that the debt was unsustainable; might a better approach have been to deal with the Greek debt problem through a mixture of conditionality and large transfers?genuine transfers, not just loans? Hence, to both 54 See also Cline (2013), in which he takes a darker view of sovereign debt sustainability in Greece. Cross-country transfers of this magnitude should not occur outside a fiscal union which exercises centralized control. Not only was it orderly, but it took place swiftly (within six months since the start of negotiations), with high participation and no significant legal disputes. The losses imposed by the restructuring did not trigger knock-on insolvencies of systemically important institutions. We conclude that even if the alternative of a large-scale official transfer had been politically feasible?which it was not?the debt restructuring was the right thing to do. The Greek restructuring was both unavoidable and successful in the sense of being orderly, reasonably quick, and in providing significant debt relief. Most importantly, it was too little, too late, or both; hence failing to clearly restore Greece?s debt sustainability. The question is whether this reflected avoidable policy mistakes or unavoidable trade-offs?in the sense that Greece and its official creditors faced difficult choices, and did their best given what was feasible. To answer this question, it is helpful to step back and recall the constraints faced by policymakers at the time.

When studied in driving simulators gastritis diet киного generic 20 mg bentyl fast delivery, the worst drivers among truckers are those who routinely got less than five hours of sleep per day (Pack et al gastritis symptoms flatulence discount bentyl 20mg on line. Recent studies have confirmed a 10 percent increase after driving 10 hours gastritis diagnosis discount 20 mg bentyl mastercard, and a 25 percent greater risk after driving 12 hours (Tucker 2000) sample gastritis diet plan generic 20 mg bentyl otc. One of the contentious aspects of the 2003 rules was the eleventh hour of driving gastritis in the antrum generic 20 mg bentyl with mastercard. As an example of how difficult it is to identify precise limits for long work hours gastritis symptoms heart attack buy bentyl 20 mg with visa, two expert investigator groups (the Virginia Tech Transportation Institute and the Pennsylvania Transportation Institute) reached different and incompatible conclusions about the eleventh hour. The Pennsylvania team found that the eleventh hour of driving posed a significant crash risk, while the Virginia Tech investigators could detect no statistical difference between the tenth and eleventh hours of driving. In other words, a 10 hour driving limit would cost more than $63 million per life saved. Sleep apnea is assessed in a sleep laboratory by measuring breathing, airflow and brain waves while an individual sleeps (Figure 2. Due to this, the brain awakens, though the person might not be aware of their disturbed sleep. Mild to moderate sleep apnea is when these brief sleep interruptions occur 5 to 30 times an hour, while severe sleep apnea is when these interruptions occur more than 30 times an hour. The researchers also identified that for certain individuals, sleep apnea may have a multiplying effect on driver fatigue. They observed that the prevalence of sleep apnea depended on the average duration of sleep prior to the study. When treated, sleepiness and morning crash risk of apneic drivers is not different from normal headaches. More information is crashes, such as an increased risk of hypertension, weight gain, at Between January 2003 and December 2005, researchers from Texas, Wisconsin, and Minnesota analyzed 339 commercial truck drivers with newly diagnosed sleep apnea. Researchers conclude that companies can reduce health care costs by identifying and treating employees with sleep apnea (Berger et al. Sleep Laboratory Assessment Each trucker who drives in interstate commerce is required to keep accurate records of his/her duty status. As with other essentially voluntary enforcement schemes (such as the tax code), cheating is believed to occur. In the case of an accident, records can be checked against the expense receipts and other paperwork. Countermeasures like cold air or a loud radio are not routinely effective (Reyner & Horne, 1998), and as described, drivers are poor judges of their fatigue levels. If they feel fatigued, they are, but those not feeling tired also may be significantly impaired. Efforts are underway to develop devices for monitoring sleepiness in real-life conditions, but so far none have been proven effective (see text box next page). Driver monitoring systems that reliably wake up drowsy drivers, without providing too many false alarms, are not available, and even if they worked as expected from a technical point of view, there is concern that such systems may result in reliance on those devices at the expense of appropriate rest (Dinges & Mallis, 1998). More recently, safety practices have focused on the higher- risk driver, based on findings that a relatively small percentage of individuals are responsible for an inordinate crash risk (Knipling et al. Surveys of fleet safety managers were used to identify those higher-risk individuals, and methods to avoid their hiring and means to monitor and modify their behavior have been published. The synthesis identifies factors relating to commercial vehicle crash risk and assesses ways that the high-risk driver can be targeted by various safety programs and practices, at both fleet and industry-wide levels. Driver fatigue-alerting technology is intended to monitor driver drowsiness, provide continual alertness level feedback to the driver, and provide alerts and warnings when the driver?s alertness level falls below a specified threshold. The objective is to identify and develop a relatively low-cost device to assure drivers are well rested. They performed a series of short and long haul field studies and made observations in simulators at the Ames Research Center. Flight crew fatigue increases with progressive flying duty and reaches a critical level after 7 to 10 hours of flying (Samel, Wegmann & Vejvoda, Figure 2. Military F-117 pilot in 1997), and that time is decreased during night time simulator being assessed in sleep flights. The Research Center also demonstrated that planned rests and naps resulted in improved alertness and performance (Rosekind et al. They developed and conducted 90 minute presentations on fatigue and hosted an interactive website. Although they are no longer funded, they maintain the website, which is available at human- factors. The module is entitled, ?Alertness Management in Flight Operations,? and it includes basic information about fatigue, sleep, sleepiness and circadian rhythms. It describes how flight operations affect physiological factors, identifies some of the misconceptions about fatigue in aviation and offers countermeasure recommendations. The aviation industry is an example of the complexities in balancing competing interests of employees (who are paid on contracts and not with an hourly rate), safety experts, economic interests and federal regulatory agencies. Currently, conflicts exist between 1) existing regulations concerning duty hours and 2) scientific evidence and recommendations from the airline pilot organizations and the National Transportation Safety Board (Holley at al. While the absolute number of commercial airline crashes is low, the percent fatigue-related is greater than that of commercial motor vehicles, where fatigue?s effects have been well publicized. Lack of mandated requirements, and economic demands have pressured carriers to reduce flight crew rest breaks to increase productivity and reduce costs. The air crashes captured on those sites corroborate the potential dire consequences of pilot fatigue demonstrated in research settings. Pilot Fatigue Woven Through Circumstances of FedEx Crash Fatigue can defeat pilots? proven performance records and progressive companies? policies. The object lesson comes from the July 26, 2002, collision with trees on final approach of a Federal Express B727 cargo jet at Tallahassee, Florida. As one of his last official acts after nine years on the board, Goglia chaired the hearing. He noted with dismay that the accident occurred even though FedEx ?is one of the more enlightened companies regarding the fatigue issue. The FedEx crash case has focused attention on this issue, as it marks at least the third crash in which the safety board has cited pilot fatigue as a contributing factor. Seafaring has overlap with emergency medical services responders because both involve working in teams or crews in unique circumstances. Also for both sites, workers rely on other members? performance, and their tasks often are accomplished under unpredictable environmental conditions. In addition, for both occupations, the effects of worker fatigue can have catastrophic consequences. Seafarers? efforts to acknowledge, identify and deal with long work hours and fatigue, especially as they relate to the Cardiff recommendations (Table 2. One aspect missing in marine worker reform efforts, which is discussed further in Section 5 (page 63), is the need to involve consideration of workers? families and other psychosocial components in planning and assessing work structures. In addition, trucking demonstrates that regulations and enforcement can only go so far in remedying problems. Current efforts to minimize driver-related accidents by identifying higher-risk individuals are examples of means to work within an existing system to improve safety. Aspects identified as important in countering seafarers? fatigue-related problems include treating fatigue as a serious threat to health of workers and the industry, using realistic staffing patterns, enforcing regulations in conjunction with a culture of safety and involving all stakeholders in reform efforts. The percentage of fatigue-related crashes may be highest in the aviation industry, and z despite multiple pilots sharing tasks on the flight deck and existing hour limits, pilot unions argue that even stricter limits on pilot hours are needed. Prior complete a one year internship studies suggested that these long work hours impaired before being licensed to practice physicians? performance. Most then become deprived interns, residents and other physicians working residents and spend two to six years long hours were prone to errors when performing repetitive in an accredited program to become tasks and activities that required sustained vigilance board certified family medicine (Samkoff & Jacques, 1991; Lingenfelser et al. Importantly, obstetrician/gynecologists, some thought that the performance deficits associated with radiologists, pathologists or one of long hours could result in patient harm (Leape, Berwick & the many other medical fields. In addition to potentially hurting patients, these receive additional fellowship training work patterns possibly were damaging physicians? health following residency. The term a highly publicized adverse patient outcome led to legal is a holdover from when they literally actions (Brensilver, Smith & Lyttle, 1998) and public lived in the hospital or house demand for reform (Kohn, Corrigan & Donaldson, 1999; throughout their training. A description of the Libby Zion case and the resultant book detailing its events is presented on page 43. At the insistence of the consumer watch group Public Citizen and with the involvement of the Occupational Health and Safety Administration (Gurjala et al. This reform sought to create a minimum standard for duty hours across all training programs. The ?downside? of resident work hour reform was a potential loss of continuity of care, reduction in trainee learning due to reduced patient exposure and disruption of the educational units that provide care in a teaching hospitals setting (Steinbrook, 2002; Charap, 2004). The relationship among continuity of care, fatigued providers and patient safety is complex (Shojania et al. Efforts to reduce fatigue and sleep deprivation among residents can result in increased discontinuity of patient care, and just as with fatigued physicians, the result also can be harmful (Cook, Render & Woods, 2000). Even since implementation of the work hour reform, those house officers benefiting from the reduction in hours have noted potential negative impact on patient care and their education (Goitein et al. Three years after initiating the reform, the effect of this universal change in resident work hours on patient safety is not known. In addition, well designed efforts to study the impact of the reform illustrate the measures needed to examine altering the work environment. Many medical metanalysis and critical topic reviews apply those criteria, and that methodology was used with the available research concerning the effects of extended work hours on patient outcomes and doctor well being. Because debate raged concerning the benefits and risks of reform, those involved critically analyzed an extensive existing literature for evidence concerning the current (prior to reform) system. Fletcher and colleagues (2004) searched the English-language literature for the last 40 years to identify articles that related physician work hours and patient safety, and beginning with more than 1200 citations, carefully reviewed 343 articles. As they pointed out, the many simulation studies showing decreased house officer performance were not ?real? patient encounters. The reviewers concluded that ?evidence on patient safety is insufficient to inform the process of reducing resident work hours? (Fletcher et al. The same group of investigators, funded by a grant from the Agency for Healthcare Research and Quality, undertook a review of the literature as it related to work hours and residents? lives (Fletcher et al. Their conclusions were similar to that of their review of hours and patient safety. The work hours and shift lengths of interns and residents are extreme and in general, much longer than physicians in practice or other professions. Although the reviewers found that some evidence suggested residents? quality of life would improve with work hour limitations, they wrote that interpreting the ?outcomes of these studies is hampered by suboptimal study design and the use of non-validated instruments. They aimed to test the hypotheses that extended work hours have a negative effect on patient safety and residents? sleep, performance and health. Those efforts illustrate study design features needed to document worker events, potential confounding variables and means to validate outcomes. A web-based survey was used to collect individual data from almost 3000 interns, from different geographic regions and a wide variety of training programs. The surveys asked about their time distribution and sleeping and waking hours, along with more than 60 other questions. Although the web is a convenient means to collect self-reported data, it also can be biased and inaccurate. Accordingly, the investigators validated the interns? self-reported measures by having a random sample also keep daily diaries. Diaries or activity logs correlate with direct observation of individuals, and the diaries were used to validate the self reported information. Data on patient errors was collected, and the researchers found that extended-duration work shifts were associated with an increased risk of significant medical errors and adverse events. However, self reports of errors are subject to recall bias and are difficult to validate. For those outcomes, it also was problematic to control for the many potential confounding factors, such as level of supervision and other work-related issues. For these events, intern fatigue was a primary variable, and those crashes were substantiated with accident reports, insurance claims, photographs or other documentation. In addition to an adverse impact from one long day of work, repeated prolonged work days also had a detrimental effect. An almost linear relationship was observed between the number of extended shifts per month and car crashes; on the typical longer work schedule (every third night), the risk of a crash on the commute from work was increased 162 percent. The same researchers who did the web-based intern survey also conducted a small prospective randomized crossover trial among interns working in the Medical Intensive Care Unit and the Coronary Care Unit at the Brigham and Women?s Hospital in Boston. Each intern served as his or her own control as they worked in random order for three weeks under two different work hour situations: 1) a traditional schedule of approximately 80 hours per week and 2) a 60 hour schedule, which also eliminated shifts longer than 24 hours. Again, the interns? habits were closely monitored, and they completed daily sleep and work hour diaries and underwent continuous ambulatory recordings for three or four days a week. In this situation the patient care outcomes could be directly assessed using direct observation by other physicians, regular chart reviews by two highly- trained nurses, voluntary intern self-reports and computerized event-detection monitoring systems. The investigators found that interns working a traditional schedule made 36 percent more serious medical errors and five times more serious diagnostic errors, both of which were highly significant differences. Even though there was less continuity of care and more transferring management among interns, errors still were fewer among the interns with more rest. Collectively, the findings from the studies demonstrated an increased risk to both residents and patients of continuing to permit long work hours and extended duration work shifts. When working long hours, physicians were at a higher risk of lapses of vigilance and committing serious medical errors, and they were more than twice as likely to crash their cars while driving home.

These hormones regulate many metabolic processes: somatic growth, cardiac, pulmonary and bone maturation, central nervous system maturation, and neuronal differentiation, regulate oxygen consumption, and protein, lipid and carbohydrate metabolism. There is evidence that thyroid hormones are necessary for surfactant synthesis and lung maturation (Biswas S et al. The importance of thyroid hormones to perinatal neural development is well established but their relation to the developmental sequelae of preterm birth is being recently studied. During the first half of gestation the thyroid hormone available to the fetus is predominantly of maternal origin. T4 from the mother is the most important source of T3 for the fetal brain and protects it from a possible hormone deficiency until birth. Once fetal thyroid secretion starts, fetal supplies are of mixed fetal and maternal origin. Although fetal thyroidal secretion is believed to constitute an increasing proportion of the hormone available to the developing fetus, maternal transfer of T4 may still contribute significantly to fetal needs (20- 50% of normal values) up to term, mitigating the consequences of inadequate fetal thyroid function. The transfer of iodine is also difficult to quantify, but the iodine content of the fetal thyroid increases progressively from less than 2 ?g at 17 weeks of gestation up to 300 ?g at term (Figure 1). Preterm infants often have low thyroxine (T4 and FreeT4) levels postnatally, a condition referred to as transient hypotiroxinemia of prematurity. Transient hypotiroxinemia can be found in approximately 35% of all premature newborns and in 50% babies born with less than 30 weeks. This occurs during an important period for brain development and low T4 levels 192 A New Look at Hypothyroidism could be a negative factor contributing to the neurodevelopment problems of very preterm infants. The precocious diagnosis and treatment of the alterations of thyroid function during the neonatal period, could have beneficial effects in the prevention of developmental abnormalities. Iodine is a trace element which is essential for the synthesis of thyroid hormones. The iodine intake of newborns is entirely dependent on the iodine content of breast milk and the formula preparations used to feed them. An inadequate iodine supply (deficiency and excess) might be especially dangerous in the case of premature babies. The iodine intake required is at least 15 ?g/kg/day in full-term infants and 30 ?g/kg/day in preterms. Newborn infants are in a situation of iodine deficiency, precisely at a stage of psychomotor and neural development which is extremely sensitive to alterations of thyroid function ( Ares et al. Prematurity T4 T from the child 4 from the child from the mother from the child cochlea from the mother cerebral cortex Myelination striatum Subarach. Shows the overlapping changes in input thyroid hormones in utero and postnatally immediately with the start of important phases of development human brain during pregnancy. At the top T4 represents the amount needed by the fetus that is entirely from maternal origin until the middle of the pregnancy, and maternal origin and fetal thereafter. They represent only the needs of T4, and from it derives the brain T3 during these phases of development. Neonatal lterations in thyroid function and hypothyroxinemia of prematurity are thought to be caused by several reasons. These include the incomplete maturation of the hypothalamic- pituitary-thyroid axis and relative immaturity of the type I iodothyronine deoidinase enzyme systems, the untimely interruption of maternal transfer of thyroid hormones to the fetus across the human placenta, maternal antibodies, postnatal drugs (dopamine, heparine, corticoids. Quite prominent among these causes are iodine deficiency during gestation and the neonatal period, and peri- and post-natal exposure to an iodine excess, usually caused by iodine-containing antiseptics and radiologic contrast media. Iodine deficiency contributes to about 30% of the hypothyroxinaemia in enterally and parenterally fed preterm infants of 27?30 weeks gestation (Morreale G 1990, Morreale G 2002, Delange 2001, 2004, Fisher 1969, 1970, 1981) pre term neonates pre term neonates 40 term neonates term neonates 12 in utero 30 8 20 in utero 4 10 term birth 0 0 12 16 20 24 28 32 36 40 44 12 16 20 24 28 32 36 40 44 Postmenstrual age in weeks Postmenstrual age in weeks Fig. Iodine requirements during the first month of life Iodine is a trace element which is essential for the synthesis of thyroid hormones. If maternal iodine deficiency in pregnancy is severe, fetal brain damage will occur. Mild/moderate iodine deficiency during pregnancy and early postnatal life is associated with neuro/psycho-intellectual deficits in infants and children. The severity is not only related to the degree of iodine deficiency, but also to the developmental phase during which it is suffered, the most severe being the consequence of iodine deficiency during the first two trimesters of pregnancy. An inadequate iodine supply might be especially dangerous in the case of premature infants, who are prematurely 194 A New Look at Hypothyroidism deprived of the maternal supply of hormones and iodine, before their own gland has been able to accumulate as much iodine as in term newborns. The iodine intake of newborns is entirely dependent on the iodine content of breast milk and the formula preparations used to feed them. Taking into consideration new information regarding iodine metabolism in premature and term newborn infants, to meet such requirements the iodine content of formulas for premature newborns should contain 20 ?g/dl, and that of first and follow-up preparations 10 ?g/ dl. The availability of iodine during the peri- and post-natal period of development should both ensure the minimal requirements and should not exceed the minimum amounts blocking their thyroid function. To reach adequate intake the iodine content of formulas for premature newborns ought to contain 20 ?g / dl, that of all other preparations 10 ?g / dl. The recommended intake of iodine in neonates reflects the observed mean iodine intake of young infants exclusively fed human milk in iodine replete areas. However, it is well established that the iodine content of breast milk is critically influenced by the dietary intake of the pregnant and lactating mother (Delange F et al. The iodine requirement in neonates was evaluated from metabolic studies by determining the values which resulted in a situation of positive iodine balance, which is required in order to insure a progressively increasing intrathyroidal iodine pool in the growing young infant (Delange F et al. In our unit we studied thyroid gland volume by ultrasound and we found that the volume varied from 0. These studies indicate that the iodine intake required in order to achieve a positive iodine balance is at least 15 ?g/kg/day in full-term infants and 30 ?g/kg/day in preterms. This corresponds approximately to 90 ?g/day and is consequently twice as high as the 1989 recommendations of 40-50 ?g/ day (National Research Council, 1999; Delange F, 2004). Iodine deficiency Iodine is a trace element that is essential for the synthesis of thyroid hormones. An inadequate iodine supply (deficiency and excess) might be especially dangerous in the case of premature babies. Premature infants are in a situation of iodine deficiency, precisely at a stage of psychomotor and neural development that is extremely sensitive to alterations of thyroid function. Iodine deficiency contributes to about 30% of the hypothyroxinaemia in enterally and parenterally fed preterm infants of 27?30 weeks gestation (Figure 1 and Figure 2) (Ares S et al. Iodine excess In normal individuals, the acute and chronic excess of iodinerarely leads to profound clinical thyroid dysfunction, because of the rapid activation of several autoregulatory mechanisms. However, in some individuals, such as newborns, the escape from the inhibitory effect of large doses of iodine is not achieved and clinical (symptomatic hypothyroidism) or subclinical hypothyroidism (asymptomatic hypothyroidism or altered serum thyroid parameters) the most frequently identified sources of excess iodine leading to problems in neonates result from the use of iodine-containing disinfectants (10,000 microg of iodine/mL) and from radiograph contrast media (250-370 mg of iodine/mL) given for radiological examination. The total concentration of iodine in plasma comprises the iodine in circulating T4 and T3, plus the circulating iodide and any iodine contained in contrast media, or other contaminating compounds. Urinary iodine concentrations above 16 microg/dL, 20 microg g/dL, and 25 microg g/dL may impair thyroid function in neonates. Some iodinated contrast agents, such as ipodate and iopanoic acid, are well- known inhibitors of all known iodothyronine deiodinases. The role of thyroid hormones on human central nervous system during fetal and postnatal life the close involvement between human brain development and thyroid hormones is widely accepted (Morreale de Escobar G et al. The effects of T3 on the central nervous system are mediated by the regulation of the expression of genes that synthesize proteins implicated in cerebral neurogenesis, neuronal migration and differentiation, axonal outgrowth, dendritic ontogeny, and synaptogenesis. They are also necessary for cerebellar neurogenesis (predominantly during early postnatal life), gliogenesis (predominantly during late fetal life to 6 months postnatally), and myelogenesis (during the second trimester of gestation to 2 years of postnatal life). Low T4 levels during neonatal life, especially if persistent, could be a negative factor contributing to the neurodevelopmental problems of very preterm infants. Indeed, retrospective studies have shown a relationship between hypothyroxinemia and developmental delay and an increased risk of disabling cerebral palsy (De Vries et al. Alterations of the thyroid function during the neonatal period risk factors There are many more associations of postnatal factors with transient alterations of thyroid function than had previously been considered in newborn infants. A oblique preventative 196 A New Look at Hypothyroidism approach may be necessary through reduction in the incidence or severity of individual illness(es). Similarly, alternatives to those drugs that interfere with the hypothalamic- pituitary-thyroid axis should be evaluated (e. The adaptive response of the thyroid axis at the interruption of the placental circulation is insufficient. Causal factors of transient alterations of thyroid function in the preterm newborn. If it develops soon after birth, it is called hypothyroidism acquired in the newborn period. Hypothyroidism in the newborn may be caused by: a missing or poorly developed thyroid gland, a pituitary gland that does not stimulate the thyroid gland or thyroid hormones that are poorly formed or do not work. The most common cause of hypothyroidism in the newborn is complete absence or underdevelopment of the thyroid gland. Endemic cretinism is caused by iodine deficiency, and is occasionally exacerbated by naturally occurring goitrogens. Dysgenesis of the thyroid gland, including agenesis (ie, complete absence of thyroid gland) and ectopy (lingual or sublingual thyroid gland) may be a cause. The incidence of congenital hypothyroidism, as detected through newborn screening, is approximately 1 out of every 3,000 births, but the incidence is different depending on the country, sex, race, ethnicity, gestational age. Less commonly, the thyroid gland is present but does not produce normal amounts of thyroid hormones. Some Hypothyroidism and Thyroid Function Alterations During the Neonatal Period 197 infants identified as having primary congenital hypothyroidism may have transient disease and not permanent congenital hypothyroidism. Family history should be carefully reviewed for information about similarly affected infants or family members with unexplained mental retardation. Neonatal screening for congenital hypothyroidism in premature infants is not as well established as in term newborns regarding age and number of samples. Congenital hypothyroidism is more common in infants with birthweights less than 2,000 g or more than 4,500 g.
