Aging Although the proximal causes of the major diseases in the United States are diverse and include a multitude of both genetic and environmental factors generic levitra plus 400 mg with visa, these diseases have one feature in common—their connection with the aging process order 400mg levitra plus free shipping. Although it is difficult to suggest that aging is a “disease,” the aging process is a genetic-based scenario that results in degenerative biologic sequellae promoting pathogenesis. Muscle strength decreases up to one-third in humans between the ages of 30 and 80. The ameliora- tion of such downstream consequences of aging, including heart disease, diabetes, and flabbiness as well as a quest for the human genes directly associated with the aging process itself, may ultimately be a target for gene therapies. Recent studies using an adeno-associated virus vector (see Chapter 4) and the gene for insulinlike growth factor 1 showed that injection of aged mice with this construct totally prevented the decrease in muscle mass seen in aging. For example, evolution has endowed individuals of certain species with the genes needed to sustain unusually long life spans. Thus, it is reasonable to envision that gene therapies could add decades to the human life span in the context of pro- moting a high quality of life in the extended years. Currently, most gene therapy protocols are phase 1 clinical trials—small clinical experiments that test feasibility and safety. The most significant outcome of the numerous cell marking and therapeutic trials appears to be a lack of observed toxicity due to gene transfer. However, a recent clinical trial has reported one death due to the approved experimental protocol (see Chapter 13). Additionally, it has come to light that other deaths have occurred in gene therapy clinical trials. However, it is unclear whether these deaths are related to the experimental therapy. The majority of human gene therapy protocols involve cancer, and the most common viral vector in use is the retrovirus. Most cancer studies are gene-marking studies where a cell is marked with a gene to elucidate metatasis or recurrence. The limited clinical experience to date does not rule out long-term adverse effects from gene therapy protocols as noted in Chapter 13. Thus, the ability to bring recent laboratory-based advances to the bedside relies on the quantity and quality of the underlying science, the carefulness used in clinical protocol design and outcome measure, as well as a multidisciplinary approach to bridging basic science and medicine. Currently, numerous basic science issues need to be addressed in the development of human gene therapy protocols. Gene Transfer Gene transfer can be achieved by two methods: direct transfer (in vivo) or laboratory manipulation (ex vivo). Utilizing these methods, gene transfer should be administered to the patient without adverse side effects. Various gene transfer protocols (systems) are currently under development and should be tailored to the clinical condition. In principle, studies in yeast have indicated that the development of artificial chromosome vectors may allow for the maintenance of transferred genes and obviating the problems of random insertion of viral constructs. Gene Expression Once a gene is transferred into a tissue or cell, expression of that gene is necessary for successful gene therapy. Currently, however, persistent high levels of gene expression are not consistently achieved in gene therapy protocols. It is unclear whether these experimental data reflect unknown cellular mechanisms needed for therapeutic gene expression, a selective disadvantage of the use of stem cells expressing transferred genes, or the failure to include appropriate regulatory elements in current gene constructs. What is clear from current human studies is that protocols that produce high levels of gene expression in mice do not reproduce similar gene expressions in clinical studies. Long-term expression of transferred genes and high levels of gene product have been reported in murine studies. But a deficiency arises when comparable pro- tocols are employed in clinical studies. Studies have relied on molecular methods of detection of gene expression rather that direct protein assays. Thus, at the current stage the lack of expression of transferred genes compromises both the clinical benefit and scientific value of gene therapy. Gene Targeting Gene therapy approaches could be enhanced by directing gene transfer and expres- sion to specific cells or tissues (see Chapter 5). Using such an approach would reduce the need for gene targeting required with in vivo transfer techniques. However, current ex vivo techniques could be enhanced by using targeting techniques such as that used in liver-cell-directed gene therapy (see Chapter 7). The use of ligands that bind to surface receptors could augment gene incorporation into the cell. Disease Pathology The identification of a genetic mutation as a cause of disease pathology is an im- portant step in gene therapy. However, equally important is the elucidation of the biological mechanisms through which the mutated polypeptide molecule induces pathogenesis. Mutations may cause loss of function so that gene therapy replaces the mutated gene product sufficiently for effective therapy.

The absence of a defined protocol hinders the analysis of the results of these examinations and makes even the simplest comparisons unreliable cheap levitra plus 400 mg amex. There is an urgent need for a properly established academic study of all of these deaths cheap 400 mg levitra plus, such as that performed in Australia under the auspices of the Australian Insti- tute of Criminology (6) cheap 400 mg levitra plus otc, to be instituted in the United Kingdom and the United States. Terminology In addition to the lack of reproducibility of the postmortem examina- tions, the terminology used by the pathologists to define the cause of death, particularly in the form required for the registration of the death, may often be idiosyncratic, and similar disease processes may be denoted by different pathologists using many different phrases. For example, damage to the heart muscle caused by narrowing of the coronary arteries by atheroma may be termed simply ischemic heart disease or it may be called myocardial ischemia resulting from coronary atheroma or even by the “lay” term, heart attack (7). This variation in terminology may lead to confusion, particularly among lay people attempting to understand the cause and the manner of death. A consid- erable amount of research (1,7) has been produced based on such lay assess- ments of the pathological features of a death, and this has, at times, resulted in increased confusion rather than clarification of the issues involved. If the issues regarding the definition of “in custody,” the variation in the postmortem examinations and the production of postmortem reports, and the use and analysis of subsequent specialist tests all raise problems within a single country, then the consideration of these deaths internationally produces almost insuperable conflicts of medical terminology and judicial systems. Clearly, a death, whether sudden or delayed, may Deaths in Custody 331 Table 1 Expected Types of Deaths in Different Phases of Custody Accidental Self- Deliberately Natural trauma Alcohol Drug inflicted inflicted Prearrest ++ +++ ++ ++ Arrest ++ +++ ++ ++ ± +++ Detention + + +++ +++ ++ ++ Interview + + ++ ++ +++ ++ Charge + + – – +++ ± occur for many reasons even in the absence of police, but because it is the involvement of police that is the sine qua non of “in custody,” deaths in the first phase must be considered to be the presence of police officers at the scene. Subsequently, an arrest may be made with or without the use of restraint tech- niques and the prisoner will then be transported to a police station. This trans- port will most commonly involve a period within a police vehicle, which may be a car, a van with seating, or some other vehicle. Many factors may determine the type of transport used and the position of the individual in that vehicle. Detention in the police station will be followed by an interview period inter- spersed with periods of time incarcerated, usually alone, within a cell. After the interview, the individual may be released directly, charged and then released, or he or she may be detained to appear before a court. It is at this point that custody moves from the police to other authorities, usually to the prison service. When considering the types of death that can occur during each of these phases, six main groups can be identified based on the reported causes of death. It is clear that different factors may lead directly to or play a major part in the death of an individual while in custody and that different factors will play their part at different phases in the period of custody (see Table 1). Acute alcohol intoxication or the deleterious effects of drugs are, in most cases, likely to have a decreasing effect because they are metabolized or excreted from the individual’s body. Therefore, they are most likely to cause death in the postarrest and early detention phases, and it is important to 332 Shepherd note that their effects will be least visible to those with the “duty of care” while the individual is out of sight, detained within a cell, particularly if he or she is alone within that cell. Similarly, the effects of trauma, whether accidentally or deliberately inflicted, are most likely to become apparent in the early phases of detention, and it would only be on rare occasions that the effects of such trauma would result in fatalities at a later stage, although this has occurred on several occasions, particularly with head injuries (7). Conversely, death resulting from self-inflicted injuries is unlikely to occur in the prearrest and arrest phases of detention but it can and does occur when the individual is placed in a cell and is not under immediate and constant supervision. On the other hand, deaths from natural causes can occur at almost any time during the arrest and detention period. It is possible that the stress (whether emotional, physical, or both) associated with the initial phases of arrest and with the subsequent, more emotionally stressful phases during detention are likely to precipitate the death of the susceptible individuals through the effects of sympathetic stimulation and adrenalin release. Deaths from natural causes should be reduced by the medical examination and supervision of detainees from the time of initial detention and throughout the period of deten- tion (see Chapter 8). However, it is quite clear that the deaths described in many reports are not “pure” (i. Individu- als with heart disease may also be under the influence of alcohol; individuals under the influence of alcohol or drugs may also have suffered trauma, either accidental or deliberate, before or during their detention. In determining the cause of death, it can therefore be extremely difficult to weigh each of the factors that could be identified during the period of detention. There is great need for early assessment and accurate diagnosis of natural disease (physical or psychiatric),alcohol or drug intoxication, and for the identification, docu- mentation, and treatment of all types of trauma. The removal of an individual’s freedom places on the police a duty of care to that individual, and it is only by the active assessment of each and every person entering police custody and the continuing care of that individual that the number of deaths in custody can be reduced. Natural Causes Apart from a few unusual cases, deaths resulting from natural causes while in police custody fall into the groups of disease processes that are com- monly associated with sudden natural death in the community. Cardiovascular Disease The most common cause of death in the community, and of sudden death particularly, is cardiac disease, and within this group, those deaths recorded as resulting from ischemic heart disease or coronary atheroma are the most com- mon. The exact definitions and criteria for the pathological diagnosis of sig- nificant ischemic heart disease (8) are not within the scope of this chapter. Although there is a clear increase in the incidence of this cause of death with age (9), it is important to remember that a small percentage of people in the younger age groups, most commonly those with hypercholesterolemia and hyperlipidemia, may also have significant coronary artery disease, and because the younger age groups are more likely to be arrested by the police, these few individuals may assume great significance. The significance of coronary atheroma is that individuals with this dis- ease are particularly prone to the development of dysrhythmias during periods of stress when their decreased ability to perfuse areas of the myocardium may result in the development of ectopic electrical foci. Deaths may be preceded by the development of classical cardiac chest pain, or it may present with sudden collapse and death without warning. Individuals suffering from significant myocardial hypertrophy resulting from chronic hypertension are also at greater risk during periods of stress.

This can be accomplished with a high-potency multiple vitamin and mineral formula discount 400mg levitra plus otc, along with additional vitamin C (minimum 500 mg three times per day) and CoQ10 (300 mg per day two weeks prior to surgery and for three months afterward) buy 400 mg levitra plus otc. Vitamin C supplementation is rarely employed in hospitals buy discount levitra plus 400 mg on line, despite the fact that it may provide significant benefits; low vitamin C status is quite common in hospitalized patients. In a study analyzing the vitamin C status of patients undergoing coronary artery bypass, the plasma concentration of vitamin C was shown to plummet by 70% in the 24 hours after coronary artery bypass surgery; this level persisted in most patients for up to two weeks after surgery. Given the importance of vitamin C, this serious depletion may deteriorate defense mechanisms against free radicals, infection, and wound repair in these patients. Supplementation appears to be essential in patients recovering from heart surgery, or any surgery, for that matter. Return of blood flow (reperfusion) after coronary artery bypass surgery results in oxidative damage to the vascular endothelium and myocardium and thus greatly increases the risk of subsequent coronary artery disease. Coenzyme Q10 is recommended in an attempt to prevent such oxidative damage after bypass surgery or angioplasty. In one study, 40 patients undergoing elective surgery either served in the control group or received 150 mg CoQ10 each day for seven days before the surgery. The treatment group also showed a statistically significant lower incidence of ventricular arrhythmias during the recovery period. These results clearly demonstrate that pretreatment with CoQ10 can play a protective role during routine bypass surgery by reducing oxidative damage. Therapeutic Considerations Nutritional Supplements From a natural perspective, there are two primary therapeutic goals in the treatment of angina: improving energy metabolism within the heart and improving blood supply to the heart. These goals are interrelated, as an increased blood flow means improved energy metabolism and vice versa. It converts free fatty acids to energy in much the same way as an automobile uses gasoline. Defects in the utilization of fats by the heart greatly increase the risk of atherosclerosis, heart attack, and angina pain. Specifically, impaired utilization of fatty acids by the heart results in accumulation of high concentrations of fatty acids within the heart muscle. This makes the heart extremely susceptible to cellular damage, which ultimately leads to a heart attack. Carnitine, pantethine, and coenzyme Q10 are essential compounds in normal fat and energy metabolism and are of extreme benefit to sufferers of angina. These nutrients prevent the accumulation of fatty acids within the heart muscle by improving the conversion of fatty acids and other compounds into energy. Antioxidants Using antioxidant supplementation is important for patients with angina. In an analysis of normal controls and patients with either stable or unstable angina, the plasma level of antioxidants has been shown to be a more sensitive predictor of unstable angina than the severity of atherosclerosis. Oral nitroglycerin is widely used in the conventional treatment of angina, but its continuous use can result in the development of tolerance (loss of effectiveness). Experimental findings indicate that tolerance is associated with increased vascular production of superoxide, a free radical form of oxygen. The superoxide molecules generated quickly degrade the nitric oxide formed from the administration of nitroglycerin and result in lower levels of intracellular regulators that promote relaxation of the coronary arteries. Because vitamin C is the main aqueous (water) phase antioxidant and free radical scavenger of superoxide and vitamin E is the main lipid (fat) phase antioxidant, their importance is obvious. Clinical trials have upheld this connection, showing that high-dose vitamin C and E supplementation can prevent the development of tolerance. A deficiency in carnitine results in a decrease in fatty acid concentrations in the mitochondria and reduced energy production. Normal heart function is critically dependent on adequate concentrations of carnitine. Although the normal heart stores more carnitine than it needs, if the heart does not have a good supply of oxygen, carnitine levels become depleted. This leads to decreased energy production in the heart and increased risk for angina and heart disease. Since angina patients have a decreased supply of oxygen, carnitine supplementation makes good sense. Several clinical trials have demonstrated that carnitine improves angina and heart disease. The results indicate that carnitine is an effective alternative to drugs in cases of angina. In one study of patients with stable angina, oral administration of 900 mg carnitine increased average exercise time and the time necessary for abnormalities to occur on a stress test (6. Carnitine, by improving fatty acid utilization and energy production in the heart muscle, may also prevent the production of toxic fatty acid metabolites. These compounds are extremely damaging, as they activate various inflammatory enzymes and disrupt cellular membrane structures. The changes in the properties of cardiac cell membranes induced by fatty acid metabolites are thought to contribute to impaired heart muscle contractility, increased susceptibility to irregular beats, and eventual death of heart tissue.
