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.

Introduction: Age-related decline in gait and balance is a contributor to morbidity in the elderly. Subclinical cerebrovascular disease, seen on magnetic resonance imaging (MRI) as white matter hyperintensities (WMH) and silent brain infarcts (SBI), is associated with impaired mobility. Less is known about the association of WMH in specific brain regions and mobility impairment. We hypothesized that anterior WMH volume would be associated with lower scores on the Short Physical Performance Battery (SPPB), a well-validated mobility scale associated with falls and mortality in the elderly. Methods: Participants in the Northern Manhattan Study MRI cohort had the SPPB measured a median of 5 years after enrollment. The SPPB has three domains with a maximum total score of 12: gait speed, chair stands, standing balance. Volumetric distributions for WMH volume across 14 brain regions (brainstem, cerebellum, and bilateral frontal, occipital, temporal, and parietal lobes, and bilateral anterior and posterior periventricular white matter) were determined separately for each hemisphere by combining bimodal image intensity distribution and atlas based methods. Multi-variable linear regression was performed to examine the association between SBI and total and regional (frontal, parietal, occipital, temporal, anterior, posterior, and brainstem) head size-corrected WMH volumes, with the total SPPB score; models were adjusted for cardiovascular disease risk factors, osteo-arthritis, and grip strength. Results: Among 668 stroke-free participants with the SPPB available, mean age at the time of assessment was 74 ±9 years, 37% were male and 70% Hispanic; the mean SPPB score was 8.2 ± 2.9, interquartile range 7-10. Mean total WMHV was 0.55±0.75cc, mean anterior WMH volume 0.18±0.24cc, and 12% of participants had SBI. In multi-variable models, total WMHV was associated with a lower SPPB (beta = -0.3 per SD of logWMH, p=0.004), while SBI was not (beta= -0.12, p=0.7). For regional WMH volumes, only greater anterior periventricular WMHV was associated with SPPB (beta= -0.29 per SD, p=0.009). Conclusions: White matter hyperintensities, especially in the anterior cerebral regions, are associated with a lower SPPB. Prevention of subclinical cerebrovascular disease is a potential target to prevent physical aging in the elderly.

Background. Elderly patients have unique age-related comorbidities that may lead to an increase in postoperative complications involving neurological, pulmonary, cardiac, and endocrine systems. There has been an increase in the number of elderly patients undergoing surgery as this portion of the population is increasing in numbers. Despite advances in perioperative anesthesia and analgesia along with improved delivery systems, monotherapy with opioids continues to be the mainstay for treatment of postop pain. Reliance on only opioids can oftentimes lead to inadequate pain control or increase in the incidence of adverse events. Multimodal analgesia incorporating regional anesthesia is a promising alternative that may reduce needs for high doses and dependence on opioids along with any potential associated adverse effects. Methods. The following databases were searched for relevant published trials: Cochrane Central Register of Controlled Trials and PubMed. Textbooks and meeting supplements were also utilized. The authors assessed trial quality and extracted data. Conclusions. Multimodal drug therapy and perioperative regional techniques can be very effective to perioperative pain management in the elderly. Regional anesthesia as part of multimodal perioperative treatment can often reduce postoperative neurological, pulmonary, cardiac, and endocrine complications. Regional anesthesia/analgesia has not been proven to improve long-term morbidity but does benefit immediate postoperative pain control. In addition, multimodal drug therapy utilizes a variety of nonopioid analgesic medications in order to minimize dosages and adverse effects from opioids while maximizing analgesic effect and benefit.

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.

Hypertension is a common disease in the elderly associated with signicant morbidity and mortality. Due to the complexity of this population, the optimal target of blood pressure (BP) control is still controversial. In this article, we conduct a literature review of trials published in English in the last 10 years which were specically designed to study the efcacy and safety of various BP targets in patients who are 70 years or older. Using these criteria, we found that the benets in the positive studies were demonstrated even with a minimal BPcontrol (systolic BP[SBP] <150 mmHg) and continued to be reported for a SBP<120 mmHg. On the other hand, keeping SBP<140 mmHg seemed to be safely achieved in elderly patients. Although the safety of lowering SBP to <120 mmHg is debated, Systolic Blood Pressure Intervention Trial study has shown no increased risk of falls, fractures, or kidney failure in elderly patients with SBP lower than this threshold. While the recent guidelines recommended to keep BP <130/80 mmHg in the elderly, more individualized approach should be considered to achieve this goal in order to avoid undesirable complications. Furthermore, further studies are required to evaluate BPtarget in very old patients or those with multiple comorbidities.

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.

OBJECTIVE To review and evaluate the medical literature concerning antiepileptic drug (AED) therapy in elderly patients. DATA SOURCES A MEDLINE search (1982–December 2004) was conducted. Bibliographies of the articles identified were also reviewed, and an Internet search engine was used to identify additional pertinent references. STUDY SELECTION AND DATA EXTRACTION Clinical studies and reviews were evaluated, and relevant information was included. DATA SYNTHESIS The elderly have the highest incidence of seizures among all age groups. Complex partial seizures are the most common, followed by primary generalized tonic–clonic seizures. An accurate diagnosis may prove difficult because of a low suspicion of epilepsy in the elderly and other diseases that may mimic seizures. Most AEDs are approved for treatment of elderly patients who have partial and tonic–clonic seizures. However, a number of age-related variables should be addressed when selecting an appropriate AED. Age-dependent differences in pharmacokinetics and pharmacodynamics of AEDs must be taken into account. Drug–drug interactions must be considered since elderly people often take multiple medications. The ultimate factor that often determines AED selection is tolerability. CONCLUSIONS Numerous factors must be considered in treating elderly patients for seizures, but maximizing the ability of patients to tolerate drug therapy is often the basis for AED selection. Special consideration should be made along several lines, including elderly patients’ cognitive functioning and their tendency to respond to lower AED concentrations.

Высокая распространенность хронической сердечной недостаточности (ХСН) в популяции пожилых пациентов наряду с устойчивым ро- стом численности пожилого населения как в России, так и в западных странах все больше привлекает внимание врачей к проблеме, связан- ной с ведением данного заболевания. Известно, что ведущим фактором риска развития ХСН является повышенное артериальное давление (АД) и большинство пациентов с ХСН имеют в анамнезе артериальную гипертонию (АГ), поэтому лечение пациентов пожилого возраста c АГ и ХСН является одним из важных направлений в профилактике прогрессирования ХСН, снижения количества госпитализаций и смерт- ности. Лечение АГ у пожилых имеет свои особенности, связанные с функциональным статусом пациентов и их способностью переносить лечение. В европейских рекомендациях (2018) пересмотрены целевые цифры АД при лечении АГ у пожилых, однако данные по целевым цифрам АД для лечения АГ у пациентов с ХСН опираются лишь на исследования, проводившиеся у больных без ХСН. Данные об оптималь- ном целевом уровне у пациентов с АГ и ХСН представлены в единичных исследованиях. В настоящей статье проанализирована взаимосвязь уровня АД и сердечно-сосудистых событий и смертности отдельно для пациентов с АГ и сердечной недостаточностью с низкой фракцией выброса левого желудочка и с сохраненной фракцией выброса левого желудочка. Результаты многих исследований показывают, что более низкий уровень систолического АД (120 мм рт. ст.) и диастолического АД (80 мм рт. ст.) ассоциирован с развитием неблагоприятных сердечно-сосудистых событий, особенно у пациентов с сердечной недостаточностью с низкой фракцией выброса левого желудочка.The high prevalence of chronic heart failure (CHF) in the elderly patients, along with the steady growth of the elderly population, both in Russia and in Western countries, is increasingly attracting the attention of doctors to the problem associated with the management of this disease. It is known that the leading risk factor for CHF is high blood pressure (BP) and most patients with CHF have a history of hypertension (H), so the treatment of elderly patients with H and CHF is the major focus in the slowing CHF progression, reducing the heart failure hospitalisation and mortality. Treatment of hypertension in the elderly has some specific features associated with the functional status of patients and their ability to tolerate treatment. The European recommendations (2018) revised target blood pressure levels in the elderly patients, however, data on target blood pressure levels in patients with CHF are based only on studies conducted in patients without CHF, data on the optimal target blood pressure levels in patients with hypertension and CHF are presented in single studies. In this article we analyze the relationship between blood pressure levels and cardiovascular events and mortality separately for patients with hypertension and heart failure with reduced ejection fraction and with preserved ejection fraction. Several studies show that lower systolic blood pressure (120 mm Hg) and diastolic blood pressure (80 mm Hg) is associated with the increased risk of cardiovascular events, especially in patients with heart failure with reduced ejection fraction.

AbstractTibial plateau fractures account for approximately 8% of fractures in the elderly population. Treatment strategies in the elderly are similar to those for younger patients; however, practitioners must account for the elevated comorbidity burden in this population. To date, few studies have analyzed age-based outcomes in patients with tibial plateau fractures. Therefore, the purpose of this study was to determine age-related variances in demographics, fracture characteristics, mechanism of injury, and complications. A 10-year retrospective review was conducted to identify patients who received treatment for a tibial plateau fracture. There were 351 patients (360 tibial plateau fractures) who were identified and subsequently stratified according to their age at the time of injury. Patients were classified as elderly if they were 65 years of age or older at the time of injury; all other patients were included in the control cohort. These two cohorts were analyzed using bivariate analysis to isolate for age-related variations with respect to risk factors, mechanism of injury, and complications. There were 351 patients (360 tibial plateau fractures) with a median follow-up of 1.84 ± 2.44 years who met inclusion criteria. There were a greater proportion of women in the elderly cohort as compared with the younger cohort (60.0 vs. 43.4%, p = 0.06). Elderly patients were significantly more likely to present with diabetes (33.3 vs. 16.1%, p = 0.01) or osteoporosis (14.3 vs. 1.6%, p = 0.001). Younger patients were significantly more likely to require further surgery to address ligament (12.6 vs. 0%, p = 0.008), meniscus (20.9 vs. 7.1%, p = 0.036), or cartilage pathology (13.6 vs. 0%, p = 0.005). There was no difference in the arthroplasty conversion rate (4.8% elderly vs. 7.9% control, p = 0.755). While elderly patients presented with a greater comorbidity burden, they had equivalent or better short-term outcomes when compared with their younger peers when treated with open reduction and internal fixation (ORIF). Despite the recent interest in primary total knee arthroplasty for elderly patients with tibial plateau fractures, the results of this study suggest that elderly patients may respond well when treated with ORIF following a tibial plateau fracture.

Objective.In this qualitative study we analyzed the (1) influence of age, comorbidity, and frailty on management goals in elderly patients with RA; (2) experiences of rheumatologists regarding the use of the Disease Activity Score at 28 joints (DAS28) to monitor disease activity; and (3) differences in management strategies in elderly patients with RA compared to their younger counterparts.Methods.Rheumatologists were purposively sampled for a semistructured interview. Two readers independently read and coded the interview transcripts. Important concepts were taxonomically categorized and combined in overarching themes by using NVivo 11 software.Results.Seventeen rheumatologists (mean age 44.8 yrs, SD 7.7 yrs; 29% male) from 9 medical centers were interviewed. Preserving an acceptable level of functioning was the most important management goal in patients ≥ 80 years and in patients with high levels of comorbidity and frailty. The DAS28 score less frequently steered the management strategy, because rheumatologists commented that comorbidity and an age-related erythrocyte sedimentation rate elevation might distort the DAS28 score. Instead, management of elderly patients highly depended on comorbidity, frailty, and their subsequent effects such as cognitive and physical decline, dependency, and polypharmacy. Presence of 1 or more of these factors frequently resulted in a less future-oriented management approach with less emphasis on the maximal prevention of joint erosions.Conclusion.The treat-to-target model is not automatically adopted in the elderly patient population. Future evidence-based RA management recommendations for elderly patients with RA are needed and should account for factors such as comorbidity and frailty.
