CONTEXT: The loss of body weight and fat late in life is associated with premature death and increased risk of disability, even after excluding elderly subjects who have a preexisting disease. Although it is important to recognize that periods of substantially positive or negative energy balance and body weight fluctuation occur as a normal part of life, weight losses greater than 5% over 6 months should be investigated. We can divide the major causes of weight loss in the elderly into 4 categories: social, psychiatric, due to medical conditions, and age-related. The clinical evaluation should include a careful history and physical examination. If these fail to provide clues to the weight loss, simple diagnostic tests are indicated. A period of watchful waiting is preferable to blind pursuit of additional diagnostic testing that may yield few useful data, if the results of these initial tests are normal. The first step in managing patients with weight loss is to identify and treat any specific causative or contributing conditions and to provide nutritional support when indicated. Non-orexigenic drugs have found an established place in the management of protein-energy malnutrition. Early attention to nutrition and prevention of weight loss during periods of acute stress, particularly during hospitalization, may be extremely important, as efforts directed at re-feeding are often unsuccessful. DESIGN: Narrative review.

Adequate protein intake and the maintenance of nitrogen equilibrium are of particular importance in the elderly because this age group is at increased risk of illness and malnutrition. The current recommendation for protein intake of healthy elderly subjects is 0.8 g/kg body weight/day, the same as for younger adults. Nitrogen balance studies in the elderly, however, revealed conflicting results; some studies suggest that not all elderly can achieve a nitrogen balance with a protein intake of 0.8 g/kg body weight/day, particularly if energy supply is not adequate. Beyond the amount of protein needed for nitrogen balance, the optimal protein intake for preservation of lean body mass, body functions, and health is of paramount interest. At present, there is insufficient longer-term research with defined health outcomes to derive recommendations in this regard. Very little is also known about the protein needs of frail and unhealthy elderly. Until more evidence is available, it seems reasonable to ensure a protein intake of at least 0.8 g/kg body weight/day in all elderly persons, particularly in those at risk of malnutrition (e.g., frail and multimorbid elderly). In addition to ascertaining adequate protein and energy intake, physical activity should be encouraged in order to increase energy expenditure and food intake and to facilitate muscle protein anabolism.

High-density lipoproteins (HDL) maintain cholesterol homeostasis through the role they play in regulating reverse cholesterol transport (RCT), a process by which excess cholesterol is transported back to the liver for elimination. However, RCT can be altered in the presence of cardiovascular risk factors, such as aging, which contributes to the increase in the incidence of cardiovascular diseases (CVD). The present study was aimed at investigating the effect of extra virgin olive oil (EVOO) intake on the cholesterol efflux capacity (CEC) of HDL, and to elucidate on the mechanisms by which EVOO intake improves the anti-atherogenic activity of HDL. A total of 84 healthy women and men were enrolled and were distributed, according to age, into two groups: 27 young (31.81 ± 6.79 years) and 57 elderly (70.72 ± 5.6 years) subjects. The subjects in both groups were given 25 mL/d of extra virgin olive oil (EVOO) for 12 weeks. CEC was measured using J774 macrophages radiolabeled with tritiated cholesterol ((3H) cholesterol). HDL subclass distributions were analyzed using the Quantimetrix Lipoprint® system. The HDL from the elderly subjects exhibited a lower level of CEC, at 11.12% (p < 0.0001), than the HDL from the young subjects. The CEC of the elderly subjects returned to normal levels following 12 weeks of EVOO intake. An analysis of the distribution of HDL subclasses showed that HDL from the elderly subjects were composed of lower levels of large HDL (L-HDL) (p < 0.03) and higher levels of small HDL (S-HDL) (p < 0.002) compared to HDL from the young subjects. A multiple linear regression analysis revealed a positive correlation between CEC and L-HDL levels (r = 0.35 and p < 0.001) as well as an inverse correlation between CEC and S-HDL levels (r = −0.27 and p < 0.01). This correlation remained significant even when several variables, including age, sex, and BMI as well as low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and glucose levels (β = 0.28, p < 0.002, and β = 0.24, p = 0.01) were accounted for. Consuming EVOO for 12 weeks modulated the age-related difference in the distribution of HDL subclasses by reducing the level of S-HDL and increasing the level of intermediate-HDL/large-HDL (I-HDL/L-HDL) in the elderly subjects. The age-related alteration of the CEC of HDL was due, in part, to an alteration in the distribution of HDL subclasses. A diet enriched in EVOO improved the functionality of HDL through an increase in I-HDL/L-HDL and a decrease in S-HDL.

1. Neutrophils from drug-free elderly subjects produced approximately 50% less cyclic AMP in response to isoprenaline than did neutrophils from young subjects. A significant difference in basal cyclic AMP levels was also evident (elderly 2.8 ± 0.37; young 4.9 ± 0.36 pmol of cAMP/107 cells; P < 0.05). 2. With a range of anti-neutrophil monoclonal antibodies no evidence of age-related neutrophil population heterogeneity was found. 3. These findings indicate that the age-related decline in β-adrenoceptor responsiveness is not due to changes in the neutrophil population. 4. The present results support the hypothesis that there is a generalized decline in β-adrenoceptor-mediated responsiveness in the elderly.

Purpose: The importance of stroke research in the elderly is increasing as America is “graying.” For most risk factors for most diseases (including stroke), the magnitude of association with incident events decreases at older ages. Potential changes in the impact of risk factors could be a “true” effect, or could be due to methodological issues such as age-related changes in residual confounding. Methods: REGARDS followed 27,748 stroke-free participants age 45 and over for an average of 5.3 years, during which 715 incident strokes occurred. The association of the “Framingham” risk factors (hypertension [HTN], diabetes, smoking, AFib, LVH and heart disease) with incident stroke risk was assessed in age strata of 45-64 (Young), 65-74 (Middle), and 75+ (Old). For those with and without an “index” risk factor (e.g., HTN), the average number of “other” risk factors was calculated. Results: With the exception of AFib, there was a monotonic decrease in the magnitude of the impact across the age strata, with HTN, diabetes, smoking and LVH even becoming non-significant in the elderly (Figure 1). However, for most factors, the increasing prevalence of other risk factors with age impacts primarily those with the index risk factor absent (Figure 2, example HTN as the “index” risk factor). Discussion: The impact of stroke risk factors substantially declined at older ages. However, this decrease is partially attributable to increases in the prevalence of other risk factors among those without the index risk factor, as there was little change in the prevalence of other risk factors in those with the index risk factor. Hence, the impact of the index risk factor is attenuated by increased risk in the comparison group. If this phenomenon is active with latent risk factors, estimates from multivariable analysis will also decrease with age. A deeper understanding of age-related changes in the impact of risk factors is needed.

Background: While tPA may be safe in the elderly, increasing age appears to augment risk of post-tPA symptomatic intracranial hemorrhage (sICH). Age-related white matter changes (ARWMC) are associated with increased sICH. Patients evaluated for acute ischemic stroke (AIS) via telestroke (TS) may not have access to MRI to allow incorporation of microbleeds in tPA decisions. We assessed if increased CT-based ARWMC was associated with increased sICH in elderly patients. Methods: Patients 80 years and older who received tPA for AIS at spoke hospitals were selected from our TS network registry from 9/2015 to 12/2018. TS spoke CT scans from patient presentation were reviewed by three of the authors for periventricular white matter (PWMC) and deep white matter (DWMC) changes. Total ARWMC score, based on the Fazekas score, was collected. Total ARWMC score was either mild (0-2), moderate (3-4), or severe (5-6). PWMC and DWMC were either mild (0-1) or moderate-severe (2-3). Logistic regression adjusted for age, sex, race, ethnicity, NIHSS and premorbid mRS was used to analyze relationship of ARWMC scores with sICH and patient-outcomes. Results: Of 241 patients, median age overall was 86 years (IQR 83-90), and 66% were female. The overall median ARWMC score was 3 (IQR 2-5). Regression analysis showed that more severe ARWMC scores did not lead to higher frequency of post-tPA ICH (moderate OR 0.57, CI 0.19-1.71; severe OR 1.32, CI 0.48-3.65) including sICH (moderate OR 0.78, CI 0.21-2.94; severe OR 2.09, CI 0.62-7.02). Similarly, severe PWMC and DWMC were not associated with increased risk of post-tPA ICH (PWMC OR 1.31, CI 0.51-3.38; DWMC OR 1.25, CI 0.52-3.01), including sICH (PWMC OR 1.61, CI 0.51-5.08; DWMC OR 1.81, CI 0.65-5.01). In our cohort, older patients had no difference in hemorrhage (ICH OR 0.93 CI 0.85-1.00: sICH OR 0.95 CI 0.86-1.04), and patients with less severe stroke were more likely to have hemorrhage (ICH OR 1.06 CI 1.02-1.10; sICH OR 1.08 CI 1.03-1.13). IRR among the CT scan readers was moderate (k=0.504). Conclusions: ARWMC scores were not associated with post-tPA ICH in the elderly. Our analysis lends support for the use of tPA despite severity of white matter disease. ARWMC should not be used to assist in tPA decision-making in elderly patients via telestroke.

Sarcopenia is a complex and multifactorial disease that includes a decrease in the number, structure and physiology of muscle fibers, and age-related muscle mass loss, and is associated with loss of strength, increased frailty, and increased risk for fractures and falls. Treatment options are suboptimal and consist of exercise and nutrition as the cornerstone of therapy. Current treatment principles involve identification and modification of risk factors to prevent the disease, but these efforts are of limited value to the elderly individuals currently affected by sarcopenia. The development of new and effective therapies for sarcopenia is challenging. Potential therapies can target one or more of the proposed multiple etiologies such as the loss of regenerative capacity of muscle, age-related changes in the expression of signaling molecules such as growth hormone, IGF-1, myostatin, and other endocrine signaling molecules, and age-related changes in muscle physiology like denervation and mitochondrial dysfunction. The present paper reviews regenerative medicine strategies that seek to restore adequate skeletal muscle structure and function including exogenous delivery of cells and pharmacological therapies to induce myogenesis or reverse the physiologic changes that result in the disease. Approaches that modify the microenvironment to provide an environment conducive to reversal and mitigation of the disease represent a potential regenerative medicine approach that is discussed herein.

ABSTRACT Background The elderly are at increased risk of both hearing loss (HL) and osteoporosis. Bone mineral density (BMD) has been putatively linked to HL. However, the roles of serum calcium concentrations and vitamin D status have yet to be elucidated. Objectives The purpose of this study was to examine the relation between vitamin D status, parathyroid hormone (PTH), total calcium, BMD, and HL in a nationally representative sample of elderly adults. Methods Using the NHANES (2005–2010), audiometry and BMD data of 1123 participants aged ≥70 y were analyzed in a cross-sectional manner. HL was defined as pure tone averages &gt;25 dB HL at 500, 1000, and 2000 Hz (low frequency); 500, 1000, 2000, and 4000 Hz (speech frequency); and 3000, 4000, 6000, and 8000 Hz (high frequency) in either ear. Multivariable logistic regression was used to examine the relation between HL and total 25-hydroxyvitamin D [25(OH)D], PTH, total calcium, and BMD, adjusting for covariates. Results In multivariable analyses, total 25(OH)D &lt; 20 ng/mL was found to be associated with greater odds of low-frequency HL (OR: 2.02; 95% CI: 1.28, 3.19) and speech-frequency HL (OR: 1.96; 95% CI: 1.12, 3.44). A 1-unit decrease in femoral neck BMD (OR: 4.55; 95% CI: 1.28, 16.67) and a 1-unit decrease in total spine BMD (OR: 6.25; 95% CI: 1.33, 33.33) were found to be associated with greater odds of low-frequency HL. Serum PTH and total calcium were not found to be associated with HL. Conclusions In the elderly, low vitamin D status was associated with low-frequency and speech-frequency HL. Low vitamin D status may be a potential risk factor for age-related HL.

Graded intraesophageal balloon distension (IEBD) has been utilized in the past to evaluate esophageal pain thresholds. With use of a technique that we have found to provide reproducible results for pain thresholds, two groups of normal individuals without esophageal symptoms or diabetes were studied. Group 1 included 10 "young" (age < 65 yr) individuals (mean age 27 yr, range 18-57 yr). Group 2 included 17 individuals age 65 yr or greater (mean age 72.5 yr, range 65-87 yr). Catheters with latex balloons (Wilson-Cook) were used in all 27 subjects with the balloon located 10 cm above the lower esophageal sphincter. Sequential inflations of 2-ml increments were performed until a total volume of 2 ml above the point of pain or to a maximum of 30 ml was reached. A series of two sequential inflations were performed on each subject on the day of the testing, and the mean value was taken to indicate pain threshold volumes for all 27 subjects. In the group of elderly volunteers, 5 subjects felt no pain even at the maximum inflatable volume of the balloon (30 ml) and were assigned a maximum threshold value of 30 ml. Mean pain threshold volumes for the young subjects was 17 +/- 0.8 ml of air (+/- SE) and for the elderly subjects was 27 +/- 1.4 ml (P < 0.01 and 95% confidence interval = 7.1-13.3). Our conclusion is that IEBD results in the esophagus indicate an age-related decrease in human visceral pain threshold.

SUMMARYBackground – The patterns of antidepressant and antipsychotìc drag prescribing have rarely been studied in large and geographically defined catchment areas. In the present study we examined the prevalence and distribution of antidepressant and antipsychotic prescribing in Lombardy, a northern Italy region of nine million inhabitants. Methods – This study used the Regional Administrative Database of Lombardy. This database includes all prescriptions reimbursed by the National Health System in the population living in this region. All antidepressant and antipsychotic prescriptions dispensed from the 1st January to the 31st December 2001 were extracted and prevalence data calculated by dividing antidepressant and antipsychotic users by the total number of male and female residents in each age group. In addition, from the Regional database of hospital admissions we extracted all patients aged 65 or above with cerebrovascular-related outcomes for the year 2002. The two databases were linked anonymously with the aim of investigating the relationship between exposure to psychotropics and occurrence of cerebrovascular accidents in the elderly. Results – During the study period 404, 238 individuals were dispensed antidepressants, yielding a prevalence of use of 2.85 (95% CI 2.84, 2.87) per 100 males and 5.92 (95% CI 5.90, 5.94) per 100 females. The prevalence of use progressively rose with age in both sexes, with the highest rates in old and very old individuals. The majority of individuals received a pharmacological treatment with selective-serotonin reuptake inhibitors only, slightly more than 12% received a treatment with tricyclic antidepressants. A total of 86, 187 subjects were dispensed antipsychotic agents, yielding a prevalence of use of 0.87 (95% CI 0.86, 0.88) per 100 males and 1.01 (95% CI 1.00, 1.02) per 100 females. The prevalence of use progressively rose with age in both sexes, with the highest rates in old and very old subjects. Concerning the relationship between exposure to second-generation antipsychotics (SGAs) and occurrence of cerebrovascular (CBV) accidents, the analysis showed a significantly increased risk of CBV events in elderly subjects exposed to SGAs in comparison with those exposed to first-generation antipsychotics (FGAs) (3, 31%, 95% CI 2, 95–3, 69 vs. 2, 37%, 95% CI 2, 19–2, 57). Finally the analysis indicated no differences in the proportion of cerebrovascular events in elderly subjects exposed to TCAs and SSRIs. Conclusions – The very high rates of antidepressant and antipsychotic drug prescribing detected in late life suggest the need of characterising these individuals in terms of medical and psychiatric characteristics, needs and quality of life. It also suggests the need for pragmatic clinical trials, carried out in the general practice, with the aim of assessing whether antidepressants are effective in these conditions. The data provide preliminary epidemiological evidence that exposure to SGAs, in comparison with exposure to FGAs, significantly increased the risk of cerebrovascular accidents in the elderly.Declaration of Interest: none.
