Medications With Nutritional Implications Medications and dietary supplements may influence the absorption, utilization, metabolism, and excretion of nutrients, and thus, nutritional status. Polypharmacy increases the risk of poor nutritional status in elderly, immunocompromised, and already malnourished, chronically ill, individuals. A common medication and nutri- tional interaction is between the anticoagulant, warfarin, and vitamin K, which compete with each other for the same binding site in the coagulation cascade (17). Immunosuppressive drugs are associated with anorexia, nausea, diarrhea, and altered taste, in addition to calcium deficiency (17–19). Clinical manifestations occur late and are nonspecific, and may also be related to other conditions or multiple nutrient deficiencies. The physical examination usually includes evaluating patients to visually inspect hair, eyes, lips, mouth, nails, and skin, and to detect signs of muscle wasting in the temporal and clavicle area. Relevant medical history includes prior surgeries, medical problems, history of alcohol use and smoking habits, current prescribed medications, and use of dietary supplements and other over-the-counter medications. It is also important to identify symptoms that influence intake and increase risk of malnutrition such as anorexia, taste changes, problems chewing or swallowing, nausea, vomiting, diarrhea, and signs of poor wound healing. These signs and symptoms may be caused by a disease, medication, or nutritional deficiency. Comorbidities The presence of other diseases often increases risk for malnutrition. The presence of end-stage renal disease and hemodialysis promote fluid accumulation, hypoparathy- roidism, bone demineralization, hyperphosphatemia, and hypocalemia. Some diseases have symptoms that may appear similar to those resulting from nutritional deficiencies. Biotin and riboflavin deficiencies include scaly, red rashes on the face and around orifices, which should be not be confused with the facial rash often found on patients with systemic lupus erythematosus. Need for Assessment of Total Dietary Intake (Food, Supplements, and Nutrient-Containing Medications) Diet is often an earlier sign of malnutrition or overnutrition than anthropometric, biochemical, clinical, or functional indices. But dietary assessment is difficult and must be done carefully to distinguish under- or malnutrition owing to diet alone (a primary deficiency) from that resulting from other causes (secondary deficiency) (20). Primary deficiency results from inadequate intake, which may be influenced by socioeconomic status and conditions such as alcohol abuse or eating disorders. Secondary nutrient deficiencies result from increased physiological needs, increased nutrient losses in feces and urine, and other causes. A complete dietary assessment includes obtaining information on other factors that may influence dietary intake, including changes in appetite, taste and smell changes, food allergies, food intolerances, dental problems, problems chewing and swallowing, Chapter 2 / Overview of Nutritional Assessment 25 oral sores and health, dietary restrictions (i. In planning interventions it may also be helpful to know about shopping and cooking habits and the frequency of meals consumed away from the home (5). Medications and dietary supplement intakes are important to consider when assessing dietary intake. Some medications provide nutrients, such as antacids containing relatively large amounts of calcium. There may be sources of amino acids, sugar, and vitamins and minerals in other medications as well. Dietary supplement intake of vitamins and minerals and other nutrients should also be included in assessing nutrient intakes. The use of other supplements, especially botanicals, may be helpful in assessing interactions with medications.

They gradually lose the ability to lead an autonomous life and in the case of severe dementia 20 mg vytorin amex cholesterol testosterone, become totally dependent on others vytorin 30 mg low price cholesterol lowering foods ireland. However, when it comes to providing support and services to people with dementia and carers in Europe, the criteria for eligibility are not always based on disability but may be dependent on an assessment of needs, old age, living alone and/or having limited financial resources. But even when support is based on disability, there may be negative consequences for people with dementia. Alzheimer Europe recently carried out a survey into the level of social support in Europe and this survey revealed some information about access to such support and disability (Alzheimer Europe, 2007). In Romania and Latvia, access to certain services/social support is limited to people with Alzheimer’s disease who have been officially recognised as being severely disabled but in Romania, the eligibility criteria are not suited to Alzheimer’s disease. There are a lot of conditions to be fulfilled so it is difficult for people with dementia to obtain this official recognition and hence access the services they need. In Hungary, people with dementia are not regarded as disabled and therefore not entitled to the benefits provided to disabled people. Austria, on the other hand, pays a care allowance for people with varying degrees of disability and this includes people with dementia. In Germany and Luxembourg, there are long-term care insurances, based on an assessment of needs but in Germany, a substantial need for care must be proven for at least * For further details, please see: http://www. According to Freter (2007), this is somewhat biased towards physical disability and does not correspond to the special needs of people with Alzheimer’s disease i. Since 2002, extra supervision has been available to people with cognitive impairments but this is not an eligibility criterion for access to services. Clearly, people with Alzheimer’s disease and other forms of dementia do have disabilities and it is essential that governments recognise this and ensure that they are not prevented from receiving appropriate services on the basis of discriminatory eligibility criteria and that the services provided respond to the real needs of people with dementia (rather than to the elderly in general or to people mainly with physical disabilities). Cox and Cook (2007) identify three distinct groups of people who have dementia at the time of death. These are: • People who reach the end of life but die from some other identifiable condition, such as cancer, before reaching the final stage of dementia. However, dementia is rarely recorded as the cause of death and autopsies are not routinely carried out in elderly people with probable dementia. Bronchopneumonia is commonly recorded as the immediate cause of death, sometimes with dementia indicated as a secondary illness (Burns et al. In some countries, dementia is not accepted as a primary cause of death on death certificates. There is a need to ensure that dementia can be recorded as the primary cause of death and that people with dementia are properly diagnosed. Until this happens, it is not possible to provide statistics on mortality for people with dementia in each member state. The results of this work will be available at the end of 2008 and would fill in some of the gaps in existing knowledge raised in this chapter. Alzheimer Europe is currently developing a database which will contain the results of the EuroCoDe study and which will enable the experts involved in the study to update their findings regularly, even after the official end of the project. Alzheimer Europe has also set up a working group on palliative care and is currently drafting recommendations for policy makers.

Studies examining the presence of IgE- sensitization in older patients with asthma in the United States describe sensitization rates between 23 buy 30mg vytorin with visa show cholesterol chart. Multicenter studies from the Netherlands  and France  reported that approximately 35 % of older patients with asthma were sensitized to at least one allergen discount 30mg vytorin otc cholesterol test kit hdl ldl. The most common aeroallergen to which older patients are sensitized is not consistent among studies, but typically includes cats , dust mites [155, 158], and cockroaches . Studies includ- ing older subjects with asthma, suggest that an atopic history may increase disease severity [162 , 163]. In a study of 45 patients>65 years of age recruited from an asthma clinic in New York City, cockroach sensitization was associated with more severe asthma as measured by airﬂow limitation and hyperinﬂation [159 ]. However, no studies have been conducted to date with antigen challenge of older patients with asthma and measurement of subsequent airway function. In the Normative Aging Study, men developing airway hyper- responsiveness after 49 years of age were more likely to be sensitized to cat (23. Nearly 50 % of the 40 patients in the Tucson Epidemiologic study of obstructive lung diseases who devel- oped asthma after the age of 60 years were skin prick positive to at least one anti- gen, compared with 26 % of the age-matched control population without asthma . In a study of 21 patients with asthma onset after 65 years of age, 81 % demonstrated a positive skin prick test to at least one allergen compared to a group of 14 patients developing asthma at <65 years, and in whom 57 % were allergen sensitized . For example, a French study recruited 1,485 patients (mean age 73 years) with a diagnosis of asthma from a total of 379 lung specialists to examine disease characteristics. Busse Although there are several unanswered questions regarding the roles of allergen sensitization in older patients with asthma including its role in disease inception, disease progression, trigger and management, allergen sensitization evaluation should be a component of asthma management and evaluation in this group, in par- ticular patients with persistent asthma. Additionally, some older patients with asthma have enjoyed clinical improvement in their asthma after treatment with anti- IgE therapy [166, 167], emphasizing that allergen sensitization should be evaluated in older patients with asthma. Between 1/3 to ½ of older adults with asthma report a current smoking history [5, 19 , 169]. In the Normative Aging Study, a his- tory of current smoking and presence of atopy was associated with increased airway hyperresponsiveness to methacholine challenge . Furthermore, cigarette smoke is a common trigger of exacerbation in adults with asthma and exacerbates the rate of lung function decline in both young and old patients with asthma [172, 173 ]. Exposure to biomass fuels, cleaning products, food preparation and chemicals increase the risk of developing asthma in younger adults . Many of these expo- sures occur in the work-space, which may not be applicable to older patients if they have retired. Although the effect of irritants on the development of asthma in older patients is less well characterized than in younger patients, exposure to dust parti- cles, art supplies, and cleaning products has been reported to induce asthma in older patients . Diesel exhaust is another potential environmental issue and it increases pulmonary neutrophilia in aged compared to younger mice with a pro- longed pulmonary inﬂammation . However, the effect of infection in older patients with asthma on these stages is less deﬁned. Observational studies have reported that nearly 50 % of subjects with asthma onset after the age of 60 years reported a prior respiratory infection . Detection of respiratory infections is more difﬁ- cult in older patients as viral culture and rapid antigen testing, which are used frequently in the pediatric population are less sensitive in the older population. Although viral infections have been traditionally investigated as an asthma trigger, the role of Chlamydia pneumonaie and other atypical infec- tions has recently come into focus, in particular with adult-onset asthma . Vaccination is an appropriate measure to attempt to alter the immune response and decrease the risk and progression of infectious diseases in older patients. Although vaccination of older patients decreases the progression of many infectious diseases, the immunologic protective response is decreased in the aged [77, 189 ]. In children and young adults, both inﬂuenza and pneumococcal vaccines reduce respi- ratory infections and rates of asthma exacerbation in patients with asthma [190 , 191]. The effect of inﬂuenza vaccination or pneumococcal vaccination has not been evaluated in reduction of asthma symptoms in older patients.
