Cognitive dysfunction in older subjects with diabetes has wide implications including increased hospitalization antibiotic resistance map myambutol 400 mg fast delivery, less ability for self-care antibiotics for acne what to expect buy myambutol 400 mg visa, reduced likelihood of specialist follow-up and increased risk of institutionalization  antibiotic resistance evolves in bacteria when purchase myambutol on line. Impaired cognitive function should be borne in mind when treating elderly subjects with diabetes antibiotic gum infection myambutol 800 mg fast delivery, as it has implications for their safe treatment; it may cause difficulty with glycemic control because of erratic taking of diet and medication, including hypoglycemia when the patient forgets earlier administration of hypoglycemic medication and takes more. Mental illness in elderly people with diabetes Cognitive impairment and dementia Diabetes and cognitive dysfunction are related and have evoked some interest over the last decade (Table 54. Impaired cognitive function has been demonstrated in elderly subjects with diabetes, but these studies were mostly not population-based, excluded subjects with dementia and generally used a large battery of tests to show the deficit . These are easily learned, bedside screening tests of mental status which test several cognitive domains such as memory, orientation, calcula- Depression Depression in diabetes is a serious co-morbidity associated with poor outcome and high health care expenditure (see Chapter 55). The presence of a major depressive disorder significantly increases the risk of diabetes , this association being apparently independent of age, gender or coexistent chronic disease . Moreover, depression was the single most important indicator of subsequent death in a group of people with diabetes admitted into hospital . Failure to recognize depression can be serious, as this is a long-term life-threatening disabling illness that can significantly damage quality of life. It is also associated with 928 Diabetes in Old Age Chapter 54 worsening diabetic control  and decreased treatment compliance (see Chapter 55) . The relationship between diabetes and depression is complex and may result from the presence of a chronic medical condition in a susceptible individual. There are also complex neuroendocrine and cytokine changes in both conditions that may provide an explanation to link these two conditions (see Chapter 55). This may delay or confuse the diagnosis, although the commonly used diagnostic assessment scales are unlikely to be invalidated. Enquiries about well-being, sleep, appetite and weight loss should be part of the routine history, with a more comprehensive psychiatric evaluation if appropriate. Depression in diabetes can be treated successfully with pharmacotherapy, and/or psychologic therapy, but blood glucose levels should be monitored closely especially with pharmacotherapy. Goals for treating patients with depression and diabetes are twofold: 1 Remission or improvement of depressive symptoms; and 2 Improvement of poor glycemic control if present . It is estimated that as many as half of all repeat prescriptions for antipsychotics occur in people aged over 65 years . A systematic review of 17 studies examined the relationship between treatment with several antipsychotic agents and the risk of developing diabetes; olanzapine had an increased odds ratio but the risk for risperidone was small . Data are still relatively limited in the elderly but suggest that the relative risk is less than for younger people with schizophrenia. Nevertheless, it seems prudent to undertake regular monitoring of weight, glucose and lipid profile . Disability Disability in elderly people with diabetes Chronic diabetic complications often cause considerable disability in older people. Moreover, one in three subjects with diabetes had been hospitalized in the previous 12 months (twice the rate of those without diabetes), and subjects with diabetes had significantly increased levels of both physical and cognitive disability. Mortality in elderly subjects with diabetes People with diabetes die prematurely, mostly from cardiovascular disease. Early reports suggested that excess rates among people with diabetes fell progressively with age, especially in those aged 65 years and over. A recent systematic review of the relationship between mortality and age has suggested a higher incidence of premature death in older subjects with diabetes . Cardiovascular mortality is primarily responsible, accounting for 42% of the overall mortality in the Verona Study. Age remains the strongest predictor of mortality; the contributions of classic cardiovascular risk factors are uncertain in older subjects with diabetes.
Hospital admissions last twice as long for older patients with diabetes compared with agematched control groups without diabetes bacteria use restriction enzymes to 400 mg myambutol for sale, with the totals averaging 7 and 8 days per year for men and women antimicrobial use guidelines buy generic myambutol on line, respectively [4 antibiotic resistance related to evolution purchase myambutol on line,6 virus not allowing internet access buy myambutol 800mg fast delivery,8]. Introducing insulin treatment increases costs fourfold, both in the community and in hospital, where bed occupancy rises to 24 days per year . Additional considerations that apply to the elderly population are described in the text. Subjects included those with previously diagnosed and undiagnosed diabetes (defined by fasting plasma glucose 7. It must be remembered that older people with diabetes, particularly those who are housebound or institutionalized, have special needs (Table 54. By the time of publication of this edition, this number is projected to rise to 285 million. The prevalence of diabetes begins to rise steadily from early adulthood, reaching a plateau in those aged 60 years or older; the data in Figure 54. This condition appears to be most prevalent in northern Europe and is rare in Asians and Africans. There are marked ethnic and geographic differences in the prevalence rates of diabetes amongst older people. This is attributed to various combinations of insulin resistance and impaired insulin secretion that result in a progressive age-related decline in glucose tolerance, which begins in the third decade and continues throughout adulthood [18,19]. Plasma glucose levels at 1 and 2 hours after the standard 75-g oral glucose challenge rise by 0. Perhaps the most important is impairment of insulin-mediated glucose disposal, especially in skeletal muscle [19,20], which is particularly marked in obese subjects (Figure 54. Insulin receptor number and binding are not consistently affected by age, and so post-receptor defects are presumably responsible. Contributory factors in some cases include increased body fat mass, physical inactivity and diabetogenic drugs such as thiazides. The ability of insulin to enhance blood flow is also considerably reduced in obese insulin-resistant subjects with diabetes; this may be etiologically important, as insulin-mediated vasodilatation is thought to account for about 30% of normal glucose disposal. The euglycemic clamp technique was used to measure the glucose disposal rate in healthy lean and obese elderly controls, and in their counterparts with diabetes. As well as insulin resistance, many elderly people with glucose intolerance show impairment of glucose-induced insulin secretion, especially in response to oral rather than intravenous glucose. Some older subjects with hyperosmolar hyperglycemic state need very small doses of insulin to reduce plasma glucose levels, although hypercatabolic or severely insulin-resistant states will require higher dosages. Thrombotic complications may occur, especially in subjects with hyperosmolar hyperglycemic state; prophylactic anticoagulation with low dose subcutaneous heparin is therefore recommended. The tendency to hyperosmolarity may be worsened in elderly people, who may not perceive thirst or drink enough to compensate for the osmotic diuresis, and are often taking diuretics . Residents of care homes are at increased risk of hyperosmolar hyperglycemic state, which is associated with appreciable mortality . Compared with the young, older patients have higher mortality and longer stays in hospital; they are also less likely to have had diabetes diagnosed previously, and more likely to have renal impairment and to require higher insulin regimens . Hypoglycemia Older patients are particularly susceptible to hypoglycemia, and this problem is often exacerbated because old people may have been given little knowledge about the symptoms and signs of hypoglycemia . Even health professionals may misdiagnose hypoglycemia as a stroke, transient ischemic attack, unexplained confusion or epileptic fit, as illustrated in the case history below. He was unconscious and the family was told by the emergency room staff that he had had a stroke and his prognosis was very poor. Initial investigations are as for younger patients, including arterial blood gases and plasma osmolality (see Chapter 34). In elderly patients, intravenous saline can often be given at a rate of 500 mL/hour for 4 hours, then reducing to 250 mL/hour; faster infusion is needed if the patient is shocked, when a central line is invaluable to monitor filling Patients with cognitive impairment or loss of the warning symptoms of hypoglycemia are especially vulnerable, as they may not recognize impending hypoglycemia and/or fail to communicate their feelings to their carers.

Pediatricians who inappropriately foster persistent parental involvement risk promoting dependency in the patient . It is important to note, however, that a shift of responsibility in diabetes management may be perceived as threatening by parent and patient and may result in feelings of neglect and anxiety. Therefore, both too much parental focus and too early a dismissal of parental responsibility can be disadvantageous to the transition process. Transition involves the shift of responsibility of care from parent to individual, and this shift may trigger or complete the process of internalization (consolidating and accepting illness), offsetting the degree of displacement that is implicit when responsibility of care does not belong to the patient themselves. Consequences of internalization can include loss of identity and subsequent reframing of identity at a time when identity is fluid and in the process of development, and loss of control and personal power, which is important for self-esteem. Again, this occurs during a developmental period when the individual may be struggling with selfesteem issues, because of physical changes and changes in peer significance. In general, the period during which transfer occurs is a time when the adolescent or young adult is adopting a new lifestyle, for Transition in the diabetes care setting the process of transition in the diabetes care setting involves both the physical transfer of an adolescent from one health care setting to the other (pediatric to adult) as well as the acquisition and practice of self-management skills and the shift of responsibility of care from parent to adolescent. The physical transfer to adult health care services requires the implementation of a specific set of diabetes management skills and knowledge as well as negotiation and self-advocacy skills that are not assumed in the pediatric health care system. Adolescent needs during transition Rarely have young people been asked what their needs are during transition. The focus on medical care may be because many adolescents had not regularly seen any other health care professional. Adolescents stated they were interested in being introduced to the diabetes nurse educator and dietitian at the adult services . The precise needs of adolescents will vary according to culture and circumstances  and so research at the service level will be required to ensure services are tailored to need. Flexibility seems to be the key, because young people may be ready to transfer to adult services at different times, dependent on their cognitive and physical development, emotional maturity and general health . The role of health professionals in this process is to tailor advice to young people based on their developmental and cognitive level . During this transitional process, adolescents with diabetes need a shared understanding of their needs from their health care provider. This requires consultation with adolescents themselves , planning, ongoing contact and feedback between care providers in the two health care systems, and evaluation of services . The research found that poor self-care, disturbed eating behavior, depression and peer relations were all associated with poor blood glucose control. Where there were good family relationships and support from parents, girls achieved better control than boys. The researchers suggest that further research should look at the reasons behind these relationships. The authors propose that monitoring of diabetes knowledge and promotion of self-efficacy from late childhood may optimize the transfer of self-care knowledge and behaviors from parents to adolescents . Adolescence and young adulthood is characterized by a number of cognitive, emotional, behavioral and social changes that can present as barriers to effective self-management, including engagement with health care services. Cognitive changes include a shift in thinking from concrete to abstract and the ability to engage in introspection. These new cognitive skills give the ability to reflect on self-identity (self-concept and self-esteem). Adolescence is also a time of experimenting with new behaviors and, in particular, risk-taking behaviors. Socially, the importance of peers significantly increases at this time and concerns with being accepted by peer group are strong. Successful transition can only be facilitated by provision of appropriate services, programs and resources.
