Abstract

BackgroundFalls are common in older adults and can lead to severe injuries. The Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) trial cluster-randomized 86 primary care practices across 10 health systems to a multifactorial intervention to prevent fall injuries, delivered by registered nurses trained as falls care managers, or enhanced usual care. STRIDE enrolled 5451 community-dwelling older adults age ≥70 at increased fall injury risk.MethodsWe assessed fall-related outcomes via telephone interviews of participants (or proxies) every 4 months. At baseline, 12 and 24 months, we assessed health-related quality of life (HRQOL) using the EQ-5D-5L and EQ-VAS. We used Poisson models to assess intervention effects on falls, fall-related fractures, fall injuries leading to hospital admission, and fall injuries leading to medical attention. We used hierarchical longitudinal linear models to assess HRQOL.ResultsFor recurrent event models, intervention versus control incidence rate ratios were 0.97 (95% confidence interval [CI], 0.93-1.00; p = 0.048) for falls, 0.93 (95% CI, 0.80-1.08; p = 0.337) for self-reported fractures, 0.89 (95% CI, 0.73-1.07; p = 0.205) for adjudicated fractures, 0.91 (95% CI, 0.77-1.07; p = 0.263) for falls leading to hospital admission, and 0.97 (95% CI, 0.89-1.06; p = 0.477) for falls leading to medical attention. Similar effect sizes (non-significant) were obtained for dichotomous outcomes (e.g., participants with ≥1 events). The difference in least square mean change over time in EQ-5D-5L (intervention minus control) was 0.009 (95% CI, -0.002 to 0.019; p = 0.106) at 12 months and 0.005 (95% CI, -0.006 to 0.015; p = 0.384) at 24 months.ConclusionsAcross a standard set of outcomes typically reported in fall prevention studies, we observed modest improvements, one of which was statistically significant. Future work should focus on patient-, practice-, and organization-level operational strategies to increase the real-world effectiveness of interventions, and improving the ability to detect small but potentially meaningful clinical effects.Clinicaltrialsgov identifier: NCT02475850.

Abstract

Background/objectivesIn the Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) study, a multifactorial intervention was associated with a nonsignificant 8% reduction in time to first serious fall injury but a significant 10% reduction in time to first self-reported fall injury relative to enhanced usual care. The effect of the intervention on other outcomes important to patients has not yet been reported. We aimed to evaluate the effect of the intervention on patient well-being including concern about falling, anxiety, depression, physical function, and disability.DesignPragmatic cluster-randomized trial of 5,451 community-living persons at high risk for serious fall injuries.SettingA total of 86 primary care practices within 10 U.S. healthcare systems.ParticipantsA random subsample of 743 persons aged 75 and older.MeasurementsThe well-being measures, assessed at baseline, 12 months, and 24 months, included a modified version of the Fall Efficacy Scale, Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and depression scales, and Late-Life Function and Disability Instrument.ResultsParticipants in the intervention (n = 384) and control groups (n = 359) were comparable in age: mean (standard deviation) of 81.9 (4.7) versus 81.8 (5.0) years. Mean scores were similar between groups at 12 and 24 months for concern about falling, physical function, and disability, whereas the intervention group's mean scores on anxiety and depression were .7 points lower (i.e., better) at 12 months and .6 to .8 points lower at 24 months. For each of these outcomes, differences between the groups' adjusted least square mean changes from baseline to 12 and 24 months, respectively, were quantitatively small. The overall difference in means between groups over 2 years was statistically significant only for depression, favoring the intervention: -1.19 (99% confidence interval, -2.36 to -.02), with 3.5 points representing a minimally important difference.ConclusionsSTRIDE's multifactorial intervention to reduce fall injuries was not associated with clinically meaningful improvements in patient well-being.

Abstract

BackgroundInjuries from falls are major contributors to complications and death in older adults. Despite evidence from efficacy trials that many falls can be prevented, rates of falls resulting in injury have not declined.MethodsWe conducted a pragmatic, cluster-randomized trial to evaluate the effectiveness of a multifactorial intervention that included risk assessment and individualized plans, administered by specially trained nurses, to prevent fall injuries. A total of 86 primary care practices across 10 health care systems were randomly assigned to the intervention or to enhanced usual care (the control) (43 practices each). The participants were community-dwelling adults, 70 years of age or older, who were at increased risk for fall injuries. The primary outcome, assessed in a time-to-event analysis, was the first serious fall injury, adjudicated with the use of participant report, electronic health records, and claims data. We hypothesized that the event rate would be lower by 20% in the intervention group than in the control group.ResultsThe demographic and baseline characteristics of the participants were similar in the intervention group (2802 participants) and the control group (2649 participants); the mean age was 80 years, and 62.0% of the participants were women. The rate of a first adjudicated serious fall injury did not differ significantly between the groups, as assessed in a time-to-first-event analysis (events per 100 person-years of follow-up, 4.9 in the intervention group and 5.3 in the control group; hazard ratio, 0.92; 95% confidence interval [CI], 0.80 to 1.06; P = 0.25). The rate of a first participant-reported fall injury was 25.6 events per 100 person-years of follow-up in the intervention group and 28.6 events per 100 person-years of follow-up in the control group (hazard ratio, 0.90; 95% CI, 0.83 to 0.99; P = 0.004). The rates of hospitalization or death were similar in the two groups.ConclusionsA multifactorial intervention, administered by nurses, did not result in a significantly lower rate of a first adjudicated serious fall injury than enhanced usual care.

Abstract

Unlike chronological age, biological age is a strong indicator of health of an individual. However, the molecular fingerprint associated with biological age is ill‐defined. To define a high‐resolution signature of biological age, we analyzed metabolome, circulating senescence‐associated secretome (SASP)/inflammation markers and the interaction between them, from a cohort of healthy and rapid agers. The balance between two fatty acid oxidation mechanisms, β‐oxidation and ω‐oxidation, associated with the extent of functional aging. Furthermore, a panel of 25 metabolites, Healthy Aging Metabolic (HAM) index, predicted healthy agers regardless of gender and race. HAM index was also validated in an independent cohort. Causal inference with machine learning implied three metabolites, β‐cryptoxanthin, prolylhydroxyproline, and eicosenoylcarnitine as putative drivers of biological aging. Multiple SASP markers were also elevated in rapid agers. Together, our findings reveal that a network of metabolic pathways underlie biological aging, and the HAM index could serve as a predictor of phenotypic aging in humans. [ABSTRACT FROM AUTHOR]

Abstract

ObjectivesThe impact of urinary incontinence (UI) on health-related quality of life (QoL) is significant yet variable, but little is known about patient-defined content areas regarding the influence of UI on QoL and whether patient-specific factors correlate with specific content areas of UI-related QoL. In order to identify the most valid content areas for a new UI-related QoL questionnaire, our primary goal was to determine the content areas of greatest concern regarding UI-related QoL among older persons with urge incontinence. The second goal was to examine the possible role of patients' explanatory style as a mediator of UI impact on health-related QoL. Data on the questionnaire will be presented elsewhere.DesignFocus groups comprising urge-incontinent persons were used to obtain verbatim descriptions of the impact of UI on QoL.SettingA university-affiliated tertiary hospital.ParticipantsCommunity-dwelling women (n = 25) and men (n = 5) more than 60 years of age, with urge incontinence, recruited from newspaper, newsletter, and radio advertisements.MeasurementsQualitative content analysis of focus group transcripts was used to determine QoL items. These were compared with previously described UI-related QoL items obtained from the literature. Subjects' statements regarding causes of UI were evaluated for predominant explanatory style.ResultsThirty-two UI-related QoL items were identified, more than half of which were not described previously. Compared with expert-defined UI-related QoL items from the literature, patient-defined items focused more on coping with embarrassment and interference from UI than on prevention of actual activity performance. Explanatory statements were made frequently by patients talking about their UI. Although positive style explanatory statements were most common, they did not correlate with any QoL items. By contrast, there was a significant correlation between negative explanatory style and six specific UI-related QoL items.ConclusionsFocus groups of older persons with urge incontinence suggest that experts and patients view the impact of urge UI on QoL differently. Whereas experts focus more on functional impact, patients more often cite the impact of UI on their emotional well-being and on the interruption of activities. In addition, the association between negative explanatory style and specific UI-related QoL items suggests that explanatory style may be an important mediator of patients' perceptions of UI-related QoL.

Abstract

Nocturia (waking to void) is prevalent among older adults. Disruption of the well-described circadian rhythm in urine production with higher nighttime urine output is its most common cause. In young adults, their circadian rhythm is modulated by the 24-h secretory pattern of hormones that regulate salt and water excretion, including antidiuretic hormone (ADH), renin, angiotensin, aldosterone, and atrial natriuretic peptide (ANP). The pattern of hormone secretion is less clear in older adults. We investigated the effect of sleep on the 24-h secretion of these hormones in healthy older adults. Thirteen participants aged ≥65 yr old underwent two 24-h protocols at a clinical research center 6 wk apart. The first used a habitual wake-sleep protocol, and the second used a constant routine protocol that removed the influence of sleep, posture, and diet. To assess hormonal rhythms, plasma was collected at 8:00 AM, 12:00 PM, 4:00 PM, and every 30 min from 7:00 PM to 7:00 AM. A mixed-effects regression model was used to compare subject-specific and mean trajectories of hormone secretion under the two conditions. ADH, aldosterone, and ANP showed a diurnal rhythm that peaked during sleep in the wake-sleep protocol. These nighttime elevations were significantly attenuated within subjects during the constant routine. We conclude that sleep has a masking effect on circadian rhythm amplitude of ADH, aldosterone, and ANP: the amplitude of each is increased in the presence of sleep and reduced in the absence of sleep. Disrupted sleep could potentially alter nighttime urine output in healthy older adults via this mechanism. NEW & NOTEWORTHY Nocturia (waking to void) is the most common cause of sleep interruption among older adults, and increased nighttime urine production is its primary etiology. We showed that in healthy older adults sleep affects the 24-h secretory rhythm of hormones that regulate salt-water balance, which potentially alters nighttime urine output. Further studies are needed to elucidate the impact of chronic insomnia on the secretory rhythms of these hormones. [ABSTRACT FROM AUTHOR]

Abstract

Research on aging is at an important inflection point, where the insights accumulated over the last 2 decades in the basic biology of aging are poised to be translated into new interventions to promote health span and improve longevity. Progress in the basic science of aging is increasingly influencing medical practice, and the application and translation of geroscience require seamless integration of basic, translational, and clinical researchers. This includes the identification of new biomarkers, novel molecular targets as potential therapeutic agents, and translational in vivo studies to assess the potential efficacy of new interventions. To facilitate the required dialog between basic, translational, and clinical investigators, a multidisciplinary approach is essential and requires the collaborative expertise of investigators spanning molecular and cellular biology, neuroscience, physiology, animal models, physiologic and metabolic processes, pharmacology, genetics, and high-throughput drug screening approaches. In an effort to better enable the cross-talk of investigators across the broad spectrum of aging-related research disciplines, a goal of our University of Pittsburgh Claude D. Pepper Older Americans Independence Center has been to reduce the barriers to collaborative interactions by promoting a common language through team science. The culmination of these efforts will ultimately accelerate the ability to conduct first-in-human clinical trials of novel agents to extend health span and life span. [ABSTRACT FROM AUTHOR]

Abstract

Background. The purpose of this study was to determine if vitamin D supplementation, 400-800 IU daily, could effectively treat vitamin D deficiency and insufficiency over 3 months. Methods. To test this hypothesis, we conducted a cross-sectional survey followed by a 3-month, open-label run-in phase prior to a randomized clinical trial. We enrolled 573 community-dwelling women age 65 or older, 373 of whom completed the run-in phase. All women received a daily multivitamin containing 400 IU of vitamin D and one to two calcium supplements containing 200 IU of vitamin D. We assessed bone mineral metabolism (including 25-hydroxyvitamin D and parathyroid hormone), markers of bone turnover, and bone mineral density. Results. Of the 553 screened participants who had baseline vitamin D levels available, 16% had vitamin D deficiency (serum vitamin D < 10 ng/ml) and 48% had vitamin D insufficiency (serum vitamin D between 10 and 20 ng/ml). Only 36% of participants had normal vitamin D levels (serum vitamin D [greater than or equal to] 20 ng/ml). Baseline vitamin D intake was negatively associated with serum parathyroid hormone (r = -0.29, p < .0001), and not associated with bone mineral density or bone resorption. Vitamin D deficiency was associated with decreased physical activity and slower gait. Of the 373 women who completed the run-in phase and received treatment with a multivitamin and vitamin D-containing calcium supplement, vitamin D deficiency decreased from 16% at baseline to 0% at 3 months, and vitamin D insufficiency decreased from 48% at baseline to 20% at 3 months (p < .001). Conclusions. We conclude that vitamin D deficiency and insufficiency, which are common among ambulatory, community-dwelling elderly women, can be normalized in 80% of patients over 3 months with vitamin D supplementation of 400-800 1U/d.
