Cystine has not been used for the purpose of mitigation of cyanide effects because its contribution to detoxification via this pathway is minor allergy treatment protocol buy discount flonase 50mcg. Cyanide inhibits the activity of some enzymes by binding to their metallic moiety allergy shots rash 50mcg flonase mastercard. By blocking the action of cytochrome c oxidase allergy symptoms nose burning buy flonase in india, histotoxic hypoxia/anoxia develops rapidly in exposed organisms (Smith 1996) allergy shots gain weight buy flonase online. The ability of cyanide to bind to some metallic ions is utilized with antidotes that induce methemoglobinemia in exposed organisms allergy medicine yorkie purchase generic flonase canada. Cyanide binds to the ferric ion of methemoglobin to form inactive cyanmethemo globin (see Section 3 allergy over the counter buy flonase 50 mcg without prescription. The disadvantage of these antidotes is that the methemoglobinemia further aggravates the depletion of oxygen from tissues; therefore, antidote-induced methemoglobin levels need to be closely followed in clinical practice. Experimentally, the antagonistic effect of sodium nitrite is improved by co-administration with atropine, an effect attributed to the suppression of bradycardia (Vick and Von Bredow 1996; Yamamoto 1995). A complex of diethylamine/nitric oxide reduced the toxicity of cyanide in mice (Baskin et al. This compound was found to have a high affinity for cyanide due to its low molecular weight, and it allows administration in 3-fold molar excess of binding sites over a lethal dose of cyanide. Interactions of cyanide with carbonyl groups of these compounds lead to formation of inert cyanohydrin intermediates (Bhattacharya and Vijayaraghavan 2002; Hume et al. In rabbits injected (subcutaneous) with high doses of potassium cyanide, the beneficial effect of dihydroxyacetone and sodium thiosulfate diminished after 1 hour, which the authors attributed to metabolism of dihydroxyacetone with concomitant release of bound cyanide; additional treatment with dihydroxyacetone was needed to prevent the death of the animals. These studies did not address the problem of lactic acidosis that follows cyanide exposure. Pharmacological approaches to finding antidotes for cyanide are also under investigation. They reported that H-7 partially prevented cellular energy depletion and increased the number of surviving cells. Neurological damage following exposure to cyanide has been associated with an influx of calcium ions and the subsequent release of biogenic amines. Accordingly, calcium channel blockers have been tested for their efficacy in preventing typical cyanide-induced changes. Diltiazem pretreatment, but not co treatment prevented a cyanide-induced decrease in dopamine (and increase in L-dopa) in the corpus striatum of rats (Mathangi and Namasivayam 2004b). The calcium channel blockers procaine (also an anesthetic) and verapamil antagonized the toxicity of potassium cyanide in mice (Jiang et al. Both compounds extended the time to death of a lethal dose of potassium cyanide and prevented the cyanide induced rise in total brain calcium. Dietary supplementation with antioxidant vitamins A, C, and E partially antagonized cyanide-induced reductions in superoxide dismutase in the liver, kidney, and lung and catalase in the kidney and lung of rabbits (Okolie and Iroanya 2003). Cyanide-induced histopathology was ameliorated by vitamin treatment; vitamin supplementation eliminated hepatic congestion in the liver (but not necrosis or fatty degeneration), eliminated glomerular, but not tubular necrosis in the kidney, and eliminated alveolar congestion and pulmonary edema in cyanide-treated rabbits. Melatonin and 6-hydroxymelatonin protect against cyanide-induced neurotoxicity (seizures, neuronal cell death) by suppressing the formation of superoxide anion radicals and lipid peroxidation (Choi and Han 2002; Maharaj et al. L and D-cysteine reduce the toxicity of cyanide to hepatocytes by increasing the pool of thiosulfate available for thiocyanate formation (Huang et al. Dexamethasone retarded hepatocyte toxicity by reducing the hydrolysis of membrane phospholipids induced by cyanide (Pastorino et al. They showed that the mechanism does not involve methemoglobin formation and suggested that nitric oxide might antagonize the respiratory depressant effects of cyanide. Other more efficient nitric oxide generators may be very useful cyanide antidotes. Fructose, but not glucose, protected primary cultures of rat hepatocytes against time-dependent toxicity of 2. The difference in efficacy between the two glycolytic substrates was attributed to fact that fructokinase has a low Km for the phosphorylation of fructose compared to the relatively high Km for hepatic glucokinase. Further research for a potent and safe antidote to mitigate cyanide toxicity is desirable, particularly among smoke inhalation victims who have carbon monoxide poisoning. In summary, the efficacy and safety of experimental treatments discussed in this section have not been compared systematically and therefore, do not replace the current therapeutic practice. It must be stressed that the therapeutic value of the antidotes mentioned above is heavily dependent on the time lapse between exposure and their use, since the usual course of inorganic cyanide poisoning is acute and proceeds at very high rates. The purpose of this figure is to illustrate the existing information concerning the health effects of cyanide. In the section that follows, data needs are identified for cyanide forms for which toxicity data were available and were, therefore, summarized in Section 3. These forms include primarily sodium cyanide, potassium cyanide, and hydrogen cyanide. As seen from Figure 3-6, information is available regarding death, systemic effects of acute exposure, and neurological effects in humans after inhalation, oral, and dermal exposure to cyanide. In addition, information is available regarding chronic systemic effects in humans after inhalation and oral exposure. Data regarding death, systemic effects of acute exposure, and neurological effects were obtained for animals following inhalation, oral, and dermal exposure to cyanide. Furthermore, information was obtained regarding systemic effects after intermediate-duration inhalation and oral exposure, and chronic oral exposure. In addition, information exists regarding developmental and reproductive effects after oral exposure of animals to cyanide. Studies involving cassava are omitted from consideration in this figure because they do not provide quantitative dose-response information for cyanide. The target organs of acute cyanide exposure are the central nervous system, respiratory system, and cardiovascular system. Neurological sequelae (see Neurotoxicity below) were reported as long-term, sometimes delayed effects such as Parkinsonism in survivors of acute poisoning incidents following inhalation (Lam and Lau 2000) or oral exposure (Carella et al. The systemic effects observed in animals included serious impairments in the central nervous system (semiconsciousness), lung (dyspnea), and heart (arrhythmia). Additional acute studies by all routes using several dose levels and examining comprehensive end points would help to determine thresholds for known target organs and for any new target organs that might be identified. The information would be useful to populations living near hazardous waste sites that can be exposed to cyanide in contaminated water or soil for a short time. No intermediate-duration studies were located regarding cyanide effects in humans. A few inhalation (Valade 1952) and oral (Jackson 1988; Kamalu 1993; Okolie and Osagie 1999; Philbrick et al. In addition, hematological, hepatic, renal, and reproductive effects may be caused by oral exposure. Studies on cyanide compounds containing metals such as copper and silver (Gerhart 1986, 1987) are inappropriate for establishing dose responses for cyanide because the metals may contribute to toxicity. It is known, however, that cyanides can rapidly penetrate the skin and similar toxic effects are presumed. Additional intermediate-duration inhalation studies using several dose levels would be useful to determine threshold levels for neurotoxicity. The information would be useful to populations living near hazardous waste sites that can be repeatedly exposed to cyanide in contaminated water or soil for periods of <1 year. Some reports of occupationally exposed workers indicated that low concentrations of hydrogen cyanide may have caused neurological, respiratory, and cardiovascular effects (Blanc et al. The route of exposure was predominantly inhalation, although dermal exposure can also occur in the work place. The studies, however, lacked either information about exposure levels or used small cohorts of workers. Studies in populations that used cassava roots as a main source of their diet described the neurological effects of cyanide consumption (Osuntokun 1972, 1980). For chronic exposure in animals, only one oral study in rats (hydrogen cyanide) was located (Howard and Hanzal 1955). However, the reliability of this study is low because of the unstable cyanide levels in their feed throughout the experiment due to evaporation of cyanide. Furthermore, no effects were found in the study besides nondose-related changes in weight gain in female rats, but not in male rats. Additional chronic-duration studies in animals would be helpful to determine thresholds for target organs. No studies were located regarding carcinogenicity of cyanide in humans or animals. The chronic toxicity studies suggested above should be designed to also analyze the carcinogencity of cyanide. The results of chronic toxicity and carcinogenicity studies would be useful to populations living near hazardous waste sites that can be repeatedly exposed to cyanide in contaminated water or soil for periods exceeding 1 year. No genotoxicity was found in one in vivo study in mice exposed orally to potassium cyanide (Friedman and Staub 1976). In vitro studies with cyanide in the form of potassium cyanide did not show any mutagenic activity in S. As there are no structural reasons to suggest that cyanide may be genotoxic and fragmentation is secondary to cytotoxicity, it does not appear that further genotoxicity studies are needed at this time, until the Kushi reverse mutation data can be replicated independently. One animal study reported increased resorptions in rats following oral exposure to a cassava diet (Singh 1981). Because some human populations use cassava roots as the main source of their diet, further information regarding this observation would be useful for these populations, but this is probably not a concern for people living in the United States. Increased gonadal weight was found in male rats in 90-day oral studies of copper cyanide and potassium silver cyanide (Gerhart 1986, 1987), but the possible contribution of the metals to the dose-response cannot be discounted. Thus, it appears that only limited value would be associated with further reproductive studies at this time. No studies were located regarding teratogenic effects in humans exposed to cyanide by any route, although hypothyroidism, attributed to elevated thiocyanate levels, has been observed in offspring as a result of maternal dietary consumption of cassava during pregnancy (Ermans et al. Developmental studies in animals were performed only following oral exposure and contradictory results were obtained. Teratogenic effects of cyanide exposure were observed in rats and hamsters fed a cassava diet (Frakes et al. However, the latter studies are flawed in that they did not include a control group not exposed to cyanide. Furthermore, growth retardation was the only effect in weanling rats in the second generation of a two generation oral exposure study with potassium cyanide. More data regarding developmental toxicity in experimental animals would be useful to identify the possible risk for humans. Studies on developmental neurotoxiocology, including postnatal behavior analysis, would provide significant information relative to child development for populations living near hazardous waste sites containing cyanide. No data were located regarding immunological effects in humans or animals after inhalation, oral, or dermal exposure to cyanide. A battery of immune function tests has not been performed in humans or animals; testing in animals under low-level exposure conditions would be useful to clarify whether cyanide is an immunotoxicant. The central nervous system is an important target for cyanide toxicity in humans and animals following exposure by all three routes. Neurological and behavioral effects were observed in humans after chronic inhalation exposure to hydrogen cyanide in the workplace (Blanc et al. Oral exposure to cyanide led to the development of severe peripheral neuropathies, and hearing and visual problems in those who used cassava as a staple in the diet (Osuntokun 1980). However, these effects may be due to a recently identified substance, scopeletin, rather than due to cyanide (Obidoa and Obasi 1991). Some neurological effects (memory loss and a Parkinsonian-type syndrome have been reported as delayed effects following accidental acute ingestion of soluble cyanide compounds (Chin and Calderon 2000; Grandas et al. Experimental studies in animals exposed to hydrogen cyanide or cyanide compounds by the inhalation (Purser et al. Behavioral changes were reported in pigs after oral exposure to potassium cyanide (Jackson 1988). Of particular value would be studies in animals that correlate morphological changes, such as demyelination, with changes in higher functions, such as learning and memory. Workers are exposed to cyanide in several industries, but usually only when not using personal protective gear (Blanc et al. Although several studies reported neurological and thyroid effects in workers chronically exposed occupationally, dose relationships of these effects are not known, and the effects may have been confounded by simultaneous exposure to other chemicals. Similarly, exact correlations between environmental exposures and cyanide levels in blood or urine were not established. Therefore, occupational and environmental studies that would provide data on exposure levels and concentrations found in body fluids would be useful. These studies might be useful for establishing cause/effect relationships that might lead to future monitoring of populations exposed to low levels of cyanide from dietary sources or contaminated waste sites. Furthermore, studies regarding the health status, including significant elevations in urinary thiocyanate as a biomarker, of such populations would be informative. Concentrations of cyanide can be measured in the blood, urine, and tissues, and the metabolite thiocyanate can be measured in blood and urine (Ballantyne 1983a; Berlin 1977; Chandra et al. Since certain amounts of cyanide can always be found in the human tissues, urine, and expired air, only exposure to high doses can be detected by this way. Cyanide is metabolized in the body to thiocyanate in a reaction that is catalyzed by the enzymes rhodanese and mercaptopyruvate sulfur transferase (Ansell and Lewis 1970). Significant elevations in thiocyanate levels have been detected in cassava-eating populations (Ermans et al. Since cyanide is eliminated from the body relatively rapidly, but thiocyanate levels are sustained for longer periods, other biomarkers of low-level exposure would be useful. The target organs of cyanide toxicity are the central nervous system and the cardiovascular system, but exposure to other chemicals may have similar effects.

Roots and Wings Parent Weekend the Roots and Wings parent weekend was held September 26-28, 2014 in Nebraska City at the Lied Lodge. The goal of this workshop was to provide: 1) families basic information on hearing loss, 2) an overview of current hearing technology, 3) knowledge on the various ways to communicate with deaf or hard of hearing individuals, 4) emotional support during the period after a family receives the diagnosis, and 5) an opportunity to network with other families. The purpose of the workshops was to help parents build skills for effective parental advocacy for their child.

Far too often, children with disabilities are among the last in line for resources and services, especially where these are scarce to begin with. Far too regularly, they are the objects simply of pity or, worse, discrimination and abuse. We contribute to their exclusion by failing to gather enough data to inform our decisions. When we fail to count these children, we are failing to help them count for all they should in their societies. This report not only examines the challenges involved in ensuring that children with disabilities have the fair access to services that is their right. Somewhere, a child is being told he cannot play because he cannot walk, or another that she cannot learn because she cannot see. And we all benefit when that girl, and all children, can read, learn and contribute. Rather, each is a sister, brother or friend who has of incapacity, dependency and difference that are a favourite dish, song or game; a daughter or son perpetuated by ignorance. Unless this changes, with dreams and the desire to fulfil them; a child children with disabilities will continue to have their with a disability who has the same rights as any rights neglected; to experience discrimination, other girl or boy. From exclusion to inclusion Yet surviving and thriving can be especially difficult for children with disabilities. They are Children with disabilities encounter different at greater risk of being poor than peers without forms of exclusion and are affected by them to disabilities. Children living in poverty are likely than boys to receive care and food and are among the least likely to enjoy the benefits of edu more likely to be left out of family interactions cation and health care, for example, but children and activities. If the child is born with an impair of exclusion, however, lies the shared experience ment, its birth might not even be registered. Children with disabili and therefore cut off from, the health, education ties are often regarded as inferior, and this exposes and social services to which they are entitled. Conversely, access to and use of Exclusion is often the consequence of invisibility. Effective families raising children with disabilities face means are available to build inclusive societies ostracism. Because of this, even loving parents in which children with and without disabilities and family members can be reluctant to report can enjoy their rights equally. Rahmatuallah, 14, who lost his leg in a landmine explosion, takes part in a training workshop for electricians at a centre for war-affected children in Kandahar, Afghanistan. In order to provide a context for and illustrate the issues under discussion, these two Conventions bear witness to a grow this report presents the results of national surveys and ing global movement dedicated to the inclusion independent studies, but even these must be interpret of children with disabilities in community life.

These issues, and promising initia to be respected and consulted, who has skills tives aimed at improving the quality and availability and aspirations worth nurturing and needs that of data, are discussed in Chapter 6 of this report. Inclusion requires society to make physical infrastructure, informa tion and the means of communication accessible can enhance access and safety for all children, so all can use them, to eliminate discrimination teachers, parents and visitors in a school, not so none is forced to suffer it and to provide pro just those who use wheelchairs.

Reasons for discontinuation during the efficacy phase included progressive disease (n=6) allergy symptoms dry mouth purchase flonase 50 mcg with mastercard, adverse events (n=8) allergy testing greenville sc order flonase 50 mcg online, death (n=3) allergy testing tempe az purchase flonase cheap, lost to follow-up (n=2) and receipt of an alternative anticancer therapy (n=4) allergy asthma treatment center queensbury ny order 50mcg flonase free shipping. Adverse events causing discontinuation prior to the second therapeutic dose were primarily hematologic toxicities allergy shots given to cats discount flonase 50 mcg with mastercard, and included thrombocytopenia (n=2) allergy treatment delhi buy flonase cheap, anemia (n=2), decreased white blood cells (n=2), nausea and vomiting (n=1), and multiple hematologic adverse events (thrombocytopenia, leukopenia, neutropenia, hemolytic anemia; n=1). Causes of death which prevented continued trial participation included renal failure secondary to disease/ascites (n=1), metabolic acidosis (n=1), and bowel perforation (n=1). Twenty-nine patients discontinued the study during the long-term follow-up phase; reasons included death (n=2), adverse events (n=6), progressive disease (n=10), receipt of an alternative anticancer therapy (n=8) and patient withdrawal of consent (n=3). Adverse events causing discontinuation during long-term follow-up included myelodysplastic syndrome (n=1) and metastatic colon cancer (n=1). Additional preferred terms, such as those representing salivary gland toxicities (dry mouth, salivary gland pain, salivary gland enlargement) and additional renal toxicities (kidney fibrosis, proteinuria, and glomerular filtration rate decreased) were added by this reviewer. The case of adenocarcinoma of the lung occurred in a patient who did not have prior treatment-related risk factors such as radiation; it is unclear whether additional risk factors such as smoking were present. Of these cases, 2 were assessed as related to the study product (event Grades 1 and 2). Of these cases, one (a Grade 2 event which occurred 22 days after treatment) was not resolved and resulted in a dose reduction. Among the additional reported renal adverse events, several (glomerular filtration rate decreased, hematuria) have a potential relationship to radiation toxicity. Confounded by hypotension, significant tumor burden and baseline mild renal impairment. Patient experienced hydronephrosis due to progressive retroperitoneal lymphadenopathy, which was recorded as resolved prior to onset of renal insufficiency. The gastrointestinal adverse events observed could be associated with the product (as suspected in the case of nausea and vomiting) or with the underlying disease (in the cases of constipation and abdominal pain), or both. An analysis of treatment-emergent adverse events by number of therapeutic doses administered was conducted. The exception was in the classinfections and infestations,which occurred in 38. The most common infections experienced included urinary tract infection, upper respiratory tract infection, candida infection, and sinusitis. Grade 3 or 4 chemistry abnormalities in more than 2% of patients included elevations in serum glucose, alkaline phosphatase (4. Grade 3-4 thrombocytopenia was seen in 50% of patients, with Grade 3-4 neutropenia and lymphopenia occurring in 59. Thirty three percent of patients demonstrated Grade 4 thrombocytopenia, and Grade 4 neutropenia and anemia were experienced by 16% and 7% of patients, respectively. The high incidence of low-grade elevation of clotting parameters may be related to nutritional deficiency of vitamin K in the setting of poor oral intake in patients with nausea and vomiting, and the use of anticoagulation as either prophylaxis or treatment of thromboses. Laboratory Evidence of Renal Impairment Thirty-eight percent of patients experienced an increase in creatinine, all of which were Grade 1 or 2. Only three of the 16 patients identified in this analysis had a reported adverse event of renal failure. Seven of these 16 patients (44%) had a history of type 1 or type 2 diabetes mellitus, including the patient who progressed to a severely decreased CrCl; all had a history of hypertension. The remaining 4 had subsequent measurements; two demonstrated recovery to baseline range of severity, and two demonstrated improvement but incomplete recovery at 12 months. A limitation to the analysis of renal failure is the lack of laboratory data beyond 12 months. A universal confounding factor in the assessment of renal dysfunction in this population is the presence of hypertension, often longstanding, which itself may contribute to the observed renal impairment. The laboratory abnormalities started to normalize within one week and did return to baseline (Grade 1). The patient experienced hypoglycemia and bleeding while taking warfarin for a deep venous thrombosis, and reported a 30 to 45-pound weight loss over the past few months. One month after the initial presentation, she was found unresponsive and admitted with hepatic encephalopathy; during the admission, liver imaging demonstrated multiple hepatic masses with right portal vein reversal of flow. Despite aggressive treatment, the patient continued to decline, with metabolic acidosis, persistent thrombocytopenia, and coagulopathy. The patient appears to have had progressive metastatic disease with liver involvement. No patients experienced systolic blood pressure >200 mm Hg or diastolic blood pressure greater than 110 mm Hg following infusion. All but one had an increase in the dose of an existing antihypertensive medication; one had a single intravenous dose of enalapril. Given the nearly universal presence of hypertension (controlled or uncontrolled) in this population, close monitoring is warranted to avoid sequelae of severe, uncontrolled hypertension. There were three arrhythmias reported as serious adverse events: ventricular tachycardia, tachycardia, and cardio-respiratory arrest (n= 1 each). Given the pathophysiology of the underlying disease (with catecholamine excess), assessment of the etiology of these events is difficult. Events that occurred in proximity to an infusion are more likely to be related; only one event occurred < 1 week after a therapeutic infusion. The drug elimination is primarily by the renal route, and renal impairment could likely increase the exposures. Thus, no accumulation is anticipated with the second therapeutic dose, as the therapeutic treatment consists of 2 single doses given at least 3 months apart. The literature data for commercial experience of these products do not suggest a cardiovascular risk. Bone marrow biopsy 9 months after the initial dose demonstrated refractory anemia with excess blasts, and cytogenetic analysis showed loss of chromosomes 3 and 5, gain of 22, and dicentric 17:20 translocation resulting in loss of 17p and 20q with a minor clone 13q deletion. His prior therapy included several cycles of cyclophosphamide, vincristine, and dacarbazine, as 131 (b) (6) well as radiation therapy. Reviewer note: this case was provided as part of the 90-day safety update and is not be reflected in cumulative analyses derived from datasets. Renal Failure Analysis of adverse event narratives for reported cases of renal failure are discussed in Significant Adverse Events in Section 8. Of these patients, all had an additional risk factor of hypertension, and 8/19 (42%) had diabetes mellitus. Of the reported adverse events of renal failure or acute kidney injury, most were mild and recovered. As previously noted, a limitation to the analysis of renal failure is the lack of laboratory data beyond 12 months. A universal confounding factor in the assessment of renal dysfunction in this population is the presence of hypertension, often severe and longstanding, which itself contributes to renal impairment. Given these observations and the potential for underlying renal impairment in this population, close monitoring of renal function warrants inclusion in product labeling. An average of these two values for each patient was converted to a percentage in the datasets. Over the course of the study, the value of patient-rated quality of life remained relatively stable. It should be noted that the number of patients for whom data was available was not 100%, and decreased from 57 to 48 over the 12-month period described above. The increase of <10% is unlikely to be clinically meaningful, but may represent stability in overall health and quality of life. Additional exploratory analyses were performed by the statistical reviewer in Section 21. These analyses are all limited by the size of the safety population and relevant subgroups. An analysis of the safety population by age revealed that patients >65 years of age experienced greater percentages of most adverse events. Human Reproduction and Pregnancy There were no reported exposures during pregnancy. Special consideration regarding radiation exposure in pediatric patients, namely greater absorbed radiation dose and a potential longer life expectancy, was included in the product labeling. This radiotherapeutic requires special licensing for handling, and will be administered in centers with specialized experience in the administration of radioactive products. Therefore, it is unlikely that drug abuse or any attendant medical issues will occur. Overdose is unlikely with proper administration since measurement of radioactivity is required prior to administration as defined in the product labeling. An overdose of the product would likely result in radiation-related toxicities consistent with those described in the product label, of potentially increased severity or duration dependent upon the dose administered. The majority of cases were highly confounded by prior therapies with known associations with secondary malignancies including leukemia and myelodysplasia. A post-marketing study to evaluate the incidence of secondary malignancies will be conducted by the Applicant; refer to Section 15 Postmarketing Requirements and Commitment, for details. In the pooled safety population, 7% (n=6) of patients developed acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome. The risk for development of secondary malignancies will be included in product labeling, and a post-marketing requirement to further assess the risk of secondary malignancy will be performed by the Applicant. Myelosuppression was also a prominent, and expected, safety signal in the pooled safety population. Most patients experienced a decrease in one or more cell lines, and severe decreases in platelets and neutrophils were common (50% and 59%, respectively). The patient did not have pulmonary metastases, which would be expected to increase the risk of radiation toxicity to the lungs. Limited information regarding the expected incidence of or risk factors for radiation pneumonitis can be extrapolated from this single case. Hypothyroidism occurred in 2% (n=2) of patients; there were no reports of thyroid neoplasia, though this has been reported in the literature. Hypothyroidism is managed with appropriate monitoring and thyroid hormone replacement. Combined, durable response in hypertension as measured by the primary endpoint and confirmed objective response are measures of direct clinical benefit in this population. Myelosuppression and gastrointestinal adverse reactions were the most common adverse effects by system organ class. The risk of myelodysplastic syndrome and leukemia was less common, occurring in 7% of the pooled safety population. In addition, the safety profile of the drug is deemed acceptable for the indicated population of patients. The study was not designed to assess radiation toxicities occurring beyond 60 days, precluding a complete safety review of this study. Given the substantial unmet medical need in this rare population, the product should be indicated for patients ages 12 and older. The the radiation reference to specific organ limits referenced were based limits was removed in favor on a widely cited literature of using updated guidelines source from 1991. A new table (Table 1) to provide the absorbed-dose threshold values for radiation toxicity in critical organs. Exposure, safety and effectiveness are likely to be the same in adolescent patients. None of the safety signals identified during the review require a Risk Evaluation and Mitigation Strategy. Submit cumulative, integrated safety analyses after 5 and after 10 years of follow-up of patients from an adequate number of clinical trials to identify and characterize the risks of myelodysplastic syndrome, acute leukemia and other secondary malignancies with Azedra; include incidence rates, time to onset, predisposing factors, and outcomes. These safety evaluations should be adequate to inform labeling of patient populations at highest risk and to provide evidence-based dose modifications and monitoring recommendations. Nevertheless, I will summarize my thoughts regarding certain pertinent aspects of the application. Orphan Indication: Malignant pheochromocytoma (and paraganglioma) is an ultrarare disease that can result in morbidity or mortality either due to the underlying tumor burden or due to excess catecholamine hormone production. A more modern analysis (data from 2007 to 2015 and published in abstract form) based on a Danish registry provided for an estimate of 4. The applicant provided for an estimate of 10 to 20%; however, the literature report provided by the applicant listed this estimate in the background of the report (and I could not determine how these data were obtained). A retrospective record review of 152 patients from Korea found 11% of patients to have metastatic disease with a mean follow-up of 41. For example, logistically, to enroll a patient into a trial, a patient would have to live in proximity to a study site (or have the resources to travel multiple times to the site) and would have to meet eligibility criteria for entry into the trial. Unmet Need Although some patients with malignant pheochromocytoma can have long survival, the majority who cannot be successfully treated with locoregional therapies and who require systemic therapy will ultimately die from their disease. About half of patients received prior radiation and about half received prior drug or biologic therapy. Clearly, there is a patient population who could potentially benefit from effective systemic therapy. I believe as a single endpoint, the reduction in blood pressure medication use (for at least six months) in an unblinded single arm trial could be problematic. To highlight the later example, a patient on a single daily dose of medication who decreases the dose by half would be perceived to have less benefit than a patient on four drugs who can discontinue three or four of them. The point estimate for the response rate was higher (32%) among the 50 patients who could receive two doses.

In this chapter, we will consider the growth in numbers for those in late adulthood, how that number is expected to change in the future, and the implications this will bring to both the United States and worldwide. We will also examine several theories of human aging, the physical, cognitive, and socioemotional changes that occur with this population, and the vast diversity among those in this developmental stage. Further, ageism and many of the myths associated with those in late adulthood will be explored. The first of the baby boomers (born from 1946-1964) turned 65 in 2011, and approximately 10,000 baby boomers turn 65 every day. By the year 2050, almost one in four Americans will be over 65, and will be expected to live longer than previous generations. Census Bureau (2014b) a person who turned 65 in 2015 can expect to live another 19 years, which is 5. This increasingly aged population has been referred to as the Graying of America. This graying is already having significant effects on the nation in many areas, including work, health care, housing, social security, caregiving, and adaptive technologies. Germany, Italy, and Japan all had at least 20% of their population aged 65 and over in 2012, and Japan had the highest percentage of elderly. Additionally, between 2012 and 2050, the proportion aged 65 and over is projected to increase in all developed countries. This number is expected to increase from 8% to 16% of the global population by 2050. Between 2010 and 2050, the number of older people in less developed countries is projected to increase more than 250%, compared with only a 71% increase in developed countries. Declines in fertility and improvements in longevity account for the percentage increase for those 65 years and older. In more developed countries, fertility fell below the replacement rate of two live births per woman by the 1970s, down from nearly three Source children per woman around 1950. Fertility rates also fell in many less developed countries from an average of six children in 1950 to an average of two or three children in 2005. As the population ages, concerns grow about who will provide for those requiring long-term care. In 2000, there were about 10 people 85 and older for every 100 persons between ages 50 and 64. The number of old requiring support from their children is expected to more than double by the year 2040 (He, Sengupta, Velkoff, & DeBarros, 2005). These families will certainly need external physical, emotional, and financial support in meeting this challenge. Life Expectancy vs Lifespan Lifespan or Maximum Lifespan is referred to as the greatest age reached by any member of a given population (or species). Life expectancy is defined as the average number of years that members of a population (or species) live. Women live longer than men around the world, and the gap between the sexes has remained the same since 1990. In high-income countries, the majority of people who die are old, while in low-income countries almost one in three deaths are in children under 5 years of age. According to the Central th Intelligence Agency (2019) the United States ranks 45 in the world for life expectancy. Many in late adulthood enjoy better health and social well-being than average and would be aging at an optimal level. In contrast, others experience poor health and dependence to a greater extent than would be considered normal. This age takes into account current age-specific mortality, morbidity, and disability risks and is referred to as the Healthy Life Expectancy. Life Expectancy in America: the overall life expectancy for a baby born in 2017 in the United States is 78. Life expectancy at birth did not change from 2016 for the non-Hispanic black population (74. Life Expectancy by Sex and Ethnicity 374 American Healthy Life Expectancy: To Figure 9. Although improvements have occurred in overall life expectancy, children born in America today may be the first generation to have a shorter life span than their parents. Much of this decline has been attributed to the increase in sedentary lifestyle and obesity. Since 1980, the obesity rate for children between 2 and 19 years old has tripled, as 20. Obesity in children is associated with many health problems, including high blood pressure, type 2 diabetes, elevated blood cholesterol levels, and psychological concerns including low self-esteem, negative body image and depression. Excess weight is associated with an earlier risk of obesity-related diseases and death. In 2007, former Surgeon General Richard Carmona stated, Because of the increasing rates of obesity, unhealthy eating habits and physical inactivity, we may see the first generation that will be less healthy and have a shorter life expectancy than their parents (p. Gender Differences in Life Expectancy Biological Explanations: Biological differences in sex chromosomes and different pattern of gene expression is theorized as one reason why females live longer (Chmielewski, Boryslawski, & Strzelec, 2016). Males can only express their X chromosome genes that come from the mother, while females have an advantage by selecting the better X chromosome from their mother or father, while inactivating the worse X chromosome. This process of selection for better genes is impossible in males and results in the greater genetic and developmental stability of females. In terms of developmental biology, women are the default sex, which means that the creation of a male individual requires a sequence of events at a molecular level. This activity and change in the direction of development results in a greater number of disturbances and developmental disorders, because the normal course of development requires many different factors and mechanisms, each of which must work properly and at a specific stage of the development. Although women are slightly more prone to autoimmune and inflammatory diseases, such as rheumatoid arthritis, the gradual deterioration of the immune system is slower in women (Caruso, Accardi, Virruso, & Candore, 2013; Hirokawa et al. Looking at the influence of hormones, estrogen levels in women appear to have a protective effect on their heart and circulatory systems (Vina, Borras, Gambini, Sastre, & Pallardo, 2005). Estrogens also have antioxidant properties that protect against harmful effects of free radicals, which damage cell components, cause mutations, and are in part responsible for the aging process. Testosterone levels are higher in men than in women and are related to more frequent cardiovascular and immune disorders. The level of testosterone is also responsible, in part, for male behavioral patterns, including increased level of aggression and violence (Martin, Poon, & Hagberg, 2011; Boryslawski & Chmielewski, 2012). This lack of judgment affects lifestyle choices, and consequently many more boys and men die by smoking, excessive drinking, accidents, drunk driving, and violence (Shmerling, 2016). Lifestyle Factors: Certainly not all the reasons women live longer than men are biological. One significant factor is that males work in more dangerous jobs, including police, fire fighters, and construction, and they are more exposed to violence. According to the Federal Bureau of Investigation (2014) there were 11,961 homicides in the U. According to the Department of Defense (2015), in 2014 83% of all officers in the Services (Navy, Army, Marine Corps and Air Force) were male, while 85% of all enlisted service members were male. As mentioned in the middle adulthood chapter, women are more religious than men, which is associated with healthier behaviors (Greenfield, Vaillant & Marks, 2009). Lastly, social contact is also important as loneliness is considered a health hazard. Nearly 20% of men over 50 have contact with their friends less than once a month, compared to only 12% of women who see friends that infrequently (Scott, 2015). Age Categories in Late Adulthood There have been many ways to categorize the ages of individuals in late adulthood. These categories are based on the conceptions of aging including, biological, psychological, social, and chronological differences. When compared to those who are older, the young-old experience relatively good health and social engagement (Smith, 2000), knowledge and expertise (Singer, Verhaeghen, Ghisletta, Lindenberger, & Baltes, 2003), and adaptive flexibility in daily living (Riediger, Freund, & Baltes, 2005). The young-old also show strong performance in attention, memory, and crystallized intelligence. This group is less likely to require long-term care, to be dependent or poor, and more likely to be married, working for pleasure rather than income, and living independently. Overall, those in this age period feel a sense of happiness and emotional well-being that Source is better than at any other period of adulthood (Carstensen, Fung, & Charles, 2003; George, 2009; Robins & Trzesniewski, 2005). It is also an unusual age in that people are considered both in old age and not in old age (Rubinstein, 2002). Old-old: Adults in this age period are likely to be living independently, but often experience physical impairments as chronic diseases increase after age 75. For example, congestive heart 377 failure is 10 times more common in people 75 and older, than in younger adults (National Library of Medicine, 2019). In fact, half of all cases of heart failure occur in people after age 75 (Strait & Lakatta, 2012). In addition, hypertension and cancer rates are also more common after 75, but because they are linked to lifestyle choices, they typically can be can prevented, lessoned, or managed (Barnes, 2011b). Oldest-old: this age group often includes people who have more serious chronic ailments among the older adult population. Females comprise more than 60% of those 85 and older, but they also suffer from more chronic illnesses and disabilities than older males (Gatz et al. In a 40 study of over 64,000 patients age 65 and older who visited an 30 emergency department, the 20 admission rates increased with age. Thirty-five% of admissions 10 after an emergency room visit 0 were the young old, almost 43% 65-74 75-84 85+ were the old-old, and nearly half Admissions Death were the oldest-old (Lee, Oh, Park, Choi, & Wee, 2018). The most common reasons for hospitalization for the oldest-old were congestive heart failure, pneumonia, urinary tract infections, septicemia, stroke, and hip fractures. In recent years, hospitalizations for many of these medical problems have been reduced. However, hospitalization for urinary tract infections and septicemia has increased for those 85 and older Levant et al. Those 85 and older are more likely to require long-term care and to be in nursing homes than the youngest-old. However, most still live in the community rather than a nursing home, as shown in Figure 9. In 2015 there Louise Calment were nearly half a million centenarians worldwide, and it is estimated from France that this age group will grow to almost 3. Most centenarians tended to be healthier than many of their peers as they were growing older, and often there was a delay in the onset of any serious disease or disability until their 90s. Additionally, 25% reached 100 with no serious chronic illnesses, such as depression, osteoporosis, heart disease, respiratory illness, or dementia (Ash et al. Centenarians are more likely to experience a rapid terminal decline in later life, meaning that for most of their adulthood, and even older adult years, they are relatively healthy in comparison to many other older adults (Ash et al. According to Guinness World Records (2016), Source Jeanne Louise Calment has been documented to be the longest living person at 122 years and 164 days old (See Figure 9. There are many theories that attempt to explain how we age, however, researchers still do not fully understand what factors contribute to the human lifespan (Jin, 2010). According to Jin (2010), modern biological theories of human aging involve two categories. The first is Programmed Theories that follow a biological timetable, possibly a continuation of childhood development. This timetable would depend on changes in gene expression that affect the systems responsible for maintenance, repair, and defense responses, (p. The second category includes Damage or Error Theories which emphasize environmental factors that cause cumulative damage in organisms.
