RESUMEN

BACKGROUND: Communicating bad news is of great interest in the geriatric field, but few works have considered the physician's point of view in this regard. OBJECTIVES: The aim of this study was to explore possible differences related to physicians' gender and work experience in how a terminal diagnosis is disclosed to older patients. METHODS: Study participants were 420 Italian physicians (277 M, 143 F) working in clinical medicine (58.2%), surgery (33.3%), or other medical departments (8.5%). They completed an anonymous multiple-choice questionnaire that investigated various issues associated with communicating bad news to terminally ill older patients. RESULTS: Men had more work experience than women (55.6% vs. 44.8% had worked for ≥23 years) and were more likely to work in surgery departments, while more women worked in clinical medicine. Most physicians declared that terminally ill older patients, if mentally competent, should always (14.4%) or generally (64.3%) be directly and openly informed of their condition. With no difference in gender, length of work experience, or specialty area, 36.9% of physicians thought that this was a human right and 18% that it would improve the patient's quality of life. Where older patients were alone, male physicians were more likely than female (30.2% vs. 8.9%) to always communicate bad news directly to them. More than 70% of physicians, especially those with longer work experience, declared that they always or often took enough time to inform the patient. Female physicians and those working in clinical medicine were more likely to need psychological help when deciding to break bad news, but only a smaller proportion declared to have received it. CONCLUSIONS: Gender and work experience may influence how physicians communicate with patients and how often they seek psychological support.

RESUMEN

Non-motor symptoms (NMSs) are common in Parkinson's disease (PD) and can precede, sometimes for several years. NMSs include, other than gastrointestinal symptoms like constipation and dysphagia, also hyposmia, weight loss and osteosarcopenia. These three NMSs seem to be inter-related and affect patients' health and quality of life. Unfortunately, patients with these symptoms usually are not initially seen by a neurologist, and by the time they are consulted, nearly ~ 80% of the dopaminergic neurons in the substantia nigra have died. To date, no guidelines exist for screening, assessment and management of NMSs in general. A better understanding of these specific NMSs, likely in the context of others, will make it possible to approach and optimise the treatment of the motor symptoms thereby enhancing the welfare of PD patients. Identifying the NMSs could be very helpful, and among them, hyposmia, weight loss and osteosarcopenia may play an important role in solving the limitations in the diagnosis of PD. A strict collaboration between general practitioners, clinicians, geriatricians and neurologists can be one approach towards the diagnosis of pre-PD. Waiting until the motor symptoms develop and the patient is finally visited by the neurologist could be too late, considering the catastrophic prognosis of the disease.

RESUMEN

The synchronic loss of bone mineral density and decrease in muscle mass, strength, and function defines the scenario of osteosarcopenia, which is associated with an increased risk of falls and fractures in older adults. An important role in preventing muscle and bone loss is played by nutritional factors, in particular the intake of proteins, calcium, magnesium and vitamin D. This review summarizes the available literature concerning the influence of protein intake and supplementation (vitamin D, Ca, Mg, branched-chain amino acids) on the decline of musculoskeletal integrity in healthy older adults. Furthermore, in this paper, we attempted to give some suggestions to build up adequate nutritional and dietary strategies against the age-related loss of muscle and bone mass.

RESUMEN

PURPOSE: Men have generally demonstrated higher pressure pain thresholds (PPT) than women. However, the possible impact of aging on the gender differences in pain perception has not been fully evaluated. In this study, we aimed to investigate the gender differences in PPT over the life course, in young, middle-aged and older adults. METHODS: This cross-sectional study involved 355 pain-free healthy individuals aged 19-95 years, divided into < 45, 45-64 and ≥ 65 years age groups. PPT were measured using Fisher's algometer. Data on anthropometry, formal education and occupation were collected for each participant, and a multidimensional geriatric assessment was performed in older individuals. RESULTS: Lower PPT values were observed in old vs young adults (21.8 ± 8.7 N/cm2 vs 59.5 ± 31.6, p < 0.0001) and in women vs men (16.3 ± 6.1 vs 42.8 ± 19.6 N/cm2, p = 0.0003). A significant interaction emerged between age and sex in influencing PPT (pinteraction = 0.03). Although women had lower mean PPT values than men in all age groups, such gender difference diminished with aging, from 42.8 ± 19.6 vs 59.5 ± 31.6 N/cm2 (p = 0.001) to 16.3 ± 6.1 vs 21.8 ± 8.7 vs N/cm2 (p = 0.003) in younger and older women vs men, respectively. CONCLUSIONS: Female gender and older age are associated with lower PPT, but such gender difference seems to decrease with aging.

RESUMEN

BACKGROUND: An adequate vitamin intake is essential for a good nutritional status, especially in older women, who are more sensitive to nutritional deficiencies. The American, European and Italian Recommended Dietary Allowances (RDAs) derive mainly from studies on adults, and it is not clear whether they also apply to elderly people. Comparing the RDAs with the actual vitamin intake of a group of healthy older women could help to clarify the real needs of elderly people. OBJECTIVE: Our aim was to compare the American, European, and Italian RDAs with the actual vitamin intake of a group of healthy older women. DESIGN: This was a cross-sectional study. PARTICIPANTS: The study included 286 healthy women aged older than 65 years. MAIN OUTCOME MEASURES: For each micronutrient, the 50th percentile of the distribution of its intake was considered as the average requirement, and the corresponding calculated RDA for our sample was the average requirement×1.2, as recommended by the US Food and Nutrition Board. This calculated RDA was then compared with the American, European, and Italian RDAs. STATISTICAL ANALYSES PERFORMED: Student's t test or the Mann-Whitney test (after checking the normal distribution of the micronutrient) for continuous variables; the χ(2) test for categorical variables. RESULTS: The calculated RDA were 2,230 µg retinol equivalents for vitamin A, 2.8 µg for vitamin B-12, 0.9 mg for thiamin, 1.4 mg for riboflavin, 3.6 mg for pantothenic acid, 1.4 mg for vitamin B-6, 320 µg for folic acid, and 115 mg for vitamin C. CONCLUSIONS: Our findings suggest that the current RDAs are adequate for older women's intake of riboflavin, vitamin B-6, and folic acid, but should be raised for vitamin B-12 and for vitamin C.

RESUMEN

OBJECTIVE: The aim of this study was to assess the impact of age on pressure pain threshold (PPT) of cervico-facial muscles in healthy geriatric subjects and to investigate the role of gender and dominance on nociception. BACKGROUND: Musculo-skeletal pain is common in the elderly, but being subjective, it risks to be underdiagnosed and undertreated. A useful method for assessment of local pain is determining PPT through pressure algometry. Ageing process seems to increase PPTs, but reference values for the assessment of pain in geriatric subjects are lacking. METHODS: In this study, PPTs in temporal muscle, masseter, sternocleidomastoid, occipital and splenius capitis of 97 healthy elderly subjects were measured using Fischer algometer. Participants were divided by age in four classes (years 65-69; 70-74; 75-79; ≥80). RESULTS: Women had lower PPTs in all muscles compared with men. Comparing PPTs obtained from the right and the left side, no significant differences were recorded neither in men nor in women. When dividing subjects by age class and education, in both genders no significant differences were observed in PPTs among the groups, neither in the right nor in the left sides. CONCLUSION: In conclusion, the present study reports reference PPT values for the cervico-facial muscles that can be applied to a population of healthy elderly subjects. After 65 years of age, further ageing does not influence PPTs in cervico-facial muscles whereas female gender has lower PPTs.

RESUMEN

HIV is often assumed to only affect younger people, and many older people do not realize that they might risk acquiring the virus. Given that sexual transmission is by far the most common way to contract HIV around the world, health care professionals do not usually pay enough attention to the possibility of HIV/AIDS in older adults, based on the common conviction that they no longer have any sexual desires and that they are sexually inactive. Nevertheless, the sexual behavior of older people is likely to change over time, as aging baby boomers progress into their 60s and 70s, meeting the criteria for "successful aging", and not conforming to the stereotype of "sexless elderly". Hence the urgent need to awareness is that HIV remains as a major health threat even in advanced age. Prompt diagnosis and treatment are especially crucial in older adults because of their general frailty and high comorbidity levels. This article reviews recent literature concerning HIV/AIDS in older adults, as regard the related epidemiological, clinical and public health issues, with a view to suggesting how the rising rate of HIV transmission in this age group might be mitigated, and shows the main points that HCP should tackle to identify older people at risk of HIV infection. In summary, there is a pressing need to develop effective prevention schemes and to adapt clinical and programmatic approaches to improve the survival of older people with HIV.

RESUMEN

OBJECTIVE: To identify the mean values and percentiles for ASMM (appendicular skeletal muscle mass) and the prevalence of sarcopenia, in terms of muscle mass reduction, using different cutoffs in a European population. DESIGN: A retrospective analysis on the dataset from a multicenter study on apparently healthy Italian adults conducted between 1999 and 2002. A significant muscle mass loss, necessary to diagnose sarcopenia, was defined in 3 different ways: (1) by subtracting 2 SDs from the mean ASMM index (ASMMI) of a young adult population (20-39 year-olds), as in the Rosetta study and the NHANES survey; (2) by calculating the 15th percentile of the distribution of our young population, corresponding to about 1 SD below the mean ASMMI; (3) by calculating the 20th percentile of the distribution of the ASMMI (as in the Health ABC study) of an elderly population. SETTING: Five centers for the diagnosis and treatment of osteoporosis in various parts of the country (Padova, Verona, Parma, Roma, Napoli). PARTICIPANTS: Participants were 1535 volunteers (1208 women and 327 men) aged 20 to 80 years, drawn from among staff members, university students, lay people contacted by word of mouth, and patients presenting spontaneously for osteoporosis screening. MEASUREMENTS: Body weight and height were measured for all participants. Body composition was assessed by DEXA, and the ASMMI was calculated as the ASMM divided by body height in meters squared. RESULTS: Both men's and women's lean mass in the arms and ASMM were highest in the young group and became lower in older age. In men, the ASMMI dropped gradually from age 20 to 29 to age 60 to 69, then remained stable in the oldest group. In women, the ASMMI gradually increased from age 20 to 29 to age 60 to 69, then dropped among the 70- to 80-year-olds. Based on the 15th percentile of the ASMMI for our young adult reference population, the cutoffs for sarcopenia were 7.59 kg/m(2) in men and 5.47 kg/m(2) in women; if the 20th percentile of the ASMMI in our elderly subjects (>65 years) was considered, the cutoffs were 7.64 kg/m(2) in men and 5.78 kg/m(2) in women. Applying the different diagnostic criteria to the those older than 65, the prevalence of sarcopenia ranged from 0% to about 20% in both genders. CONCLUSION: The 15th percentile (or 1 SD below the mean) of the ASMMI of our young adults, and the 20th percentile of this index for an elderly reference population proved more effective in identifying cases of sarcopenia than subtracting 2 SD from the mean ASMMI of a young adult population.

RESUMEN

The intermediate and advanced stages of Alzheimer's disease (AD) are frequently associated with weight loss (WL), but WL may even precede the onset of cognitive symptoms. This review focuses on the possible aetiologic and temporal relationships between AD and WL. When WL occurs some years before any signs of cognitive impairment, it may be a risk factor for dementia due to deficiency of several micronutrients, such as vitamins and essential fatty acids, and consequent oxidative tissue damage. The leptin reduction associated with WL may also facilitate cognitive decline. The mechanisms potentially inducing WL in AD include lower energy intake, higher resting energy expenditure, exaggerated physical activity, or combinations of these factors. A hypermetabolic state has been observed in animals with AD, but has not been confirmed in human subjects. This latter mechanism could involve amyloid assemblies that apparently increase the circulating cytokine levels and proton leakage in mitochondria. WL may be caused by patients' increased physical activity as they develop abnormal motor behaviour (restlessness and agitation) and waste energy while trying to perform daily activities. During the course of AD, patients usually find it increasingly difficult to eat, so they ingest less food. AD-related neurodegeneration also affects brain regions involved in regulating appetite. The caregiver has an important role in ensuring an adequate food intake and controlling behavioural disturbances. In conclusion, WL is closely linked to AD, making periodic nutritional assessments and appropriate dietary measures important aspects of an AD patient's treatment.

RESUMEN

BACKGROUND: Aging is generally accompanied by changes in body composition, muscle mass and strength, leading to a decline in motor and functional performance. Physical activity and eating habits could be involved in modulating this paraphysiological deterioration. Aim of our study was to investigate changes in body composition, diet and physical performance in healthy, elderly females over a 3-year follow-up. METHODS: 92 healthy elderly females (70.9±4.0 years) attending a twice-weekly mild fitness program were eligible for the study. They were assessed at baseline and again after 3 years in terms of clinical history, diet, body composition by DEXA, resting energy expenditure, handgrip strength, knee extensor isometric/isotonic strength, and functional performance measured using the Short Physical Performance Battery (SPPB). RESULTS: After 3 years, women had a significant decline in muscle strength (∆ isotonic: -1.4±4.3 kg, ∆ isokinetic: -2.0±6.3 kg, ∆ handgrip: -3.2±5.0 kg; p<0.001) and physical performance (∆ walking time: 0.71±0.9 s, ∆ walking speed: -0.25±0.35 m/s; p<0.001), while their weight and body composition parameters did not change, except for a small decrease in appendicular skeletal muscle mass (-0.4±1.4 kg). There was a significant drop in calorie (∆:-345.7±533.1 kcal/d; p<0.001) and protein intake (∆:-0.14±0.23 g/d; p<0.001), while resting energy expenditure remained stable. ∆ calorie intake correlated with the variation in 4-meter walking time (r: 0.34; p<0.01). CONCLUSIONS: With advancing age, physical performance declines even in healthy, fit females despite a spare of weight and body composition. This decline in physical activity could lead to a lower calorie intake, which would explain why there is no variation in body weight.

RESUMEN

BACKGROUND AND AIMS: Chronic mesenteric ischemia in older patients is a challenge for the physician because it coincides with a vague and non-specific clinical presentation with abdominal pain. It can frequently cause diagnostic errors and lead to legal consequences. The aim of this work was to evaluate the literature on chronic mesenteric ischemia and focus on the limited data concerning the geriatric population. METHODS: This research focused on observational studies, randomized controlled trials, and clinical reports (excluding case reports and reviews) dealing with patients at least 65 years old with a clinical or instrumental diagnosis of chronic intestinal ischemia, published between 2000 and 2010. The search was conducted in PubMed using the following key words: chronic ischemic splanchnic disease, chronic mesenteric ischemia, angina abdominis, chronic abdominal angina, intestinal ischemia. RESULTS: We selected 925 articles with the key words as follows: chronic mesenteric ischemia in 355 cases; chronic ischemic splanchnic disease in 46; angina abdominis in 4; abdominal angina in 242; and chronic intestinal ischemia in 278. We then excluded articles judged scarcely pertinent, case reports, reviews, works concentrating only on diagnostic, methodological, instrumental and surgical approaches, and articles based on animal or experimental models. This selection left us with 13 articles (after excluding duplicates), only three of which were considered valid for our purposes. CONCLUSIONS: Our review indicates that there is a shortage of useful literature on chronic intestinal ischemic disease diagnosed in the older adults, and the appropriate geriatric management of these patients is consequently not well established.

RESUMEN

AIMS: The aim of this study was to assess, in a natural setting, the development of cognitive, behavioral and functional performance of elderly dementia patients treated with cholinesterase inhibitors (ChEIs) during a 21-month follow-up. Another aim was to compare patterns of clinical changes in relation to patients' level of cognitive impairment at the beginning of therapy. METHOD: Of the 1987 elderly demented patients seen at our unit, 143 met the inclusion/ exclusion criteria, were followed for at least 21 months, and were thus included in the study. At baseline and each control point (up to 21 months), patients were scored for Mini Mental State Examination (MMSE), Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL). RESULTS: After 21 months' treatment with ChEIs, patients showed a significant reduction in MMSE, ADL and IADL values. The MMSE score decreased by 1.7 points/year (95% CI -2.1; -1.3), irrespective of initial cognitive level, and was lower than that expected in non-treated patients (-3/-4 points/year). CONCLUSION: ChEI therapy is effective in slowing the progression of dementia, even in the long term, irrespective of baseline cognitive level.

RESUMEN

Aging-related physical changes do not necessarily lead to a decline in sexual functioning: good physical and mental health, a positive attitude toward sex in later life, and access to a healthy partner are associated with continued sexual activity, and regular sexual expression is associated with good physical and mental health. However, it is usually assumed that older adults do not have sexual desires, and elderly people often find it difficult to discuss this topic with their doctor. There are many potential barriers concerning sexuality in older age: the lack of a healthy sexual partner, depression, the monotony of a repetitive sexual relationship, a spouse's physical unattractiveness, hormone variability, and illness and/or iatrogenic factors. Adaptive coping strategies can considerably mitigate the impact of such factors, however, and one way of contributing to breaking down barriers and taboos is undoubtedly to ensure that physicians are willing to discuss their patients' sexual history. The aim of this review was to explore the barriers and taboos to sexual expression in seniors, to propose strategies to foster this aspect of their lives, and to help physicians investigate the sexual history of their elderly patients.

RESUMEN

Mesenteric vascular obstruction is difficult to characterize, since it may produce differing acute or chronic clinical pictures and various organic symptoms, such as ischemic colitis and abdominal angina. The diagnosis of chronic mesenteric ischemia (CMI) is thus still mainly based on historic diagnostic criteria drawn up before non-invasive radiological imaging of the mesenteric vessels became widespread, and before the current demographic developments leading to a rise in the number of older patients with multiple pathologies. With this premise, we studied the clinical condition of 85 patients aged over 65 years of age, submitted to angio-CT scan for reasons other than neoplastic and general pathologies which may cause alterations in mesenteric blood flow, and without the typical symptoms of acute intestinal ischemia. Of these, 34 patients presented occlusion of at least one mesenteric vessel and 13 were affected by multivessel injury. Compared with controls, patients with mesenteric artery disease had lower BMI (24.9+/-3.3 vs 26.8+/-4.5) and longer hospital stays (14 vs 6 days), and were more frequently affected by vasculopathies in other districts (97.1% vs 80.4%), but the only bowel symptom present was diarrhea (21.2% vs 5.9%). These patients also took more benzodiazepines and acetylsalicylic acid. The results of stepwise logistic analysis of length of hospital stay, vasculopathies, diarrhea, and use of benzodiazepines yielded a predictive model with an AUC (area under the curve) of 0.81. Our data show that some features characterizing CMI in the geriatric population differ from those of the general population.

RESUMEN

BACKGROUND AND AIMS: Global fat mass distribution seems to correlate with different levels of cardio-metabolic risk; centrally distributed fat carries a high risk of cardiovascular disease, while lower limb adiposity may have a protective effect against insulin resistance. Reference data regarding body composition have already been published for the Italian population; the aim of this study was to add reference values for trunk and lower limb fat mass, and their ratio (TLR), developing percentile distributions for age brackets between 20 and 80 years. METHODS: A retrospective analysis of a multicenter, cross-sectional study was conducted and 1,570 healthy Italian adults (1,241 females and 329 males) were selected. The regional fat mass, measured by dual-energy X-ray absorptiometry total body scan, was analyzed and the TLR was calculated. RESULTS: In both genders we observed higher trunk fat mass values in older subjects against a smaller difference in BMI values. The leg fat mass was higher in old men, while it was similar in women at different ages. The TLR values in older subjects doubled those of younger subjects in both genders (62% in males and 71% in females). CONCLUSIONS: The identified ranges for trunk, leg fat mass, and TLR may be used as reference values to describe the global fat mass distribution in healthy individuals and to identify states of altered body fat distribution.

RESUMEN

Taste disorders are common among older people and may have serious consequences on their health status: each of the five main flavors (salty, sweet, sour, bitter and umami) has a specific function and a declining taste acuity or taste loss predisposes the elderly to a higher risk of developing certain diseases. Taste disorders often go unrecognized or underestimated in elderly people, however, and there is little medical literature on this issue. This study focused on analyzing the existing literature, paying particular attention to the causes of taste disorders in the elderly and their potential consequences. The most common causes of taste disorders are drug use (21.7%), zinc deficiency (14.5%) and oral and systemic diseases (7.4% and 6.4%, respectively). All these factors can have a negative effect on gustatory system deficiencies due to physiological changes associated with aging. Elderly people are liable to have several chronic diseases and to routinely need multiple medications, and this carries a particular risk of taste disorders or severe loss of the ability to taste the five basic flavors. It is noteworthy that the most useful drugs for treating chronic diseases typical of the elderly are also a potential cause of taste disorders, so periodically reviewing pharmacological therapies is not just a matter of good clinical practice, but also helps to prevent or contain taste disorders. Assessing gustatory function should be a part of any comprehensive geriatric assessment, especially in elderly hospital outpatients or inpatients, or institutionalized cases, with severe conditions that require multiple pharmacological therapies, as well as in elderly patients who are malnourished or at risk of malnutrition, with a view to limiting the modifiable causes of taste disorders.

RESUMEN

BACKGROUND & AIMS: To establish reference values for limb composition, fat-free mass (FFM) and fat mass (FM) in Italian adults for gender-specific age brackets 20-80 years old and to assess age-related regional changes in body composition. METHODS: A multicenter, retrospective study was conducted on 1571 healthy subjects, 1240 women and 331 men. Regional FFM and FM were measured by dual-energy X-ray absorptiometry. FM was expressed as % of limb weight. RESULTS: FFM in men diminished with age in both arms and legs, with reference ranges (25th -75th percentile) of 3.8-4.6 kg and 10.4-12.2 kg, respectively for 20-29 year-olds, and 3.1-3.9 kg and 8.2-10.4 kg for 70-79 year-olds. Women's arm FFM remained stable with aging (reference values 1.7-2.2 kg), decreasing in their legs (6.2-7.2 kg for 20-29 year-olds, 5.5-6.5 kg for 70-79 year-olds). Limb FM% increased with age in both genders: the reference values were 9-15% (arms) and 12-21% (legs) for 20-29 year-old men, and 19-26% and 19-29%, respectively, for 70-79 year-olds; for women's arms, they were 25-36% for 20-29 year-olds and 36-48% for 70-79 year-olds, while their leg FM remained the same with aging, i.e. 32-40%. CONCLUSIONS: These data complete the published reference values for whole body composition, enabling physiological or pathological changes in limb composition to be identified in Caucasian populations living in the Mediterranean area.

RESUMEN

A diagnosis of hypothyroidism in the elderly can easily be overlooked if we rely exclusively on its clinical presentation because this may be highly non-specific, since the signs and symptoms of the disease are common to other diseases typical of old age, and even to the normal aging process. Imaging diagnostics (ultrasound or CT), when considered alone, are also of little use for the purpose of clarifying thyroid gland function. We report here on a case of primary hypothyroidism that was diagnosed late because the correlated signs and symptoms (asthenia, bradycardia, pleural effusions, hyponatremia, worsening renal and respiratory insufficiency, hoarseness) had previously been attributed to the normal aging process and to the patient's other health conditions (Parkinson's disease, PD; chronic obstructive pulmonary disease, COPD). After a couple of weeks of treatment with levothyroxine and liothyronine, there were clinical and laboratory evidences of an improvement in the patient's condition. She became more reactive, with a shriller voice. The pleural effusion disappeared, and so did the bradycardia. Laboratory tests showed normal sodium levels, and the renal insufficiency had improved. The lack of specificity of the clinical presentation of hypothyroidism in the elderly might justify the routine measurement of thyroid-stimulating hormone in these patients.
