Int J Nurs Sci 2024; 11:241-257. [PMID: 38707687 PMCID: PMC11064592 DOI: 10.1016/j.ijnss.2024.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 03/01/2024] [Accepted: 03/06/2024] [Indexed: 05/07/2024] Open
Abstract
Objectives Chronic dyspnea, a distressing symptom in patients with complex chronic conditions, is linked to higher risks of mortality. This study aimed to identify nursing interventions that could improve self-management for complex chronic patients, thereby enhancing control over chronic dyspnea. The findings intend to guide nursing care strategies that promote self-management among this population. Methods We searched the databases Medline, Scopus, Web of Science, CINAHL, Cochrane Database of Systematic Reviews (CDSR), and Joanna Briggs Institute (JBI) databases were searched in December 2023. We included adult patients with complex chronic conditions with chronic dyspnoea. The team screened articles collaboratively, using Rayyan software. A qualitative appraisal was performed according to JBI Critical Appraisal Checklist tools. The review protocol is registered under the number CRD42023456021. Results Our review included 18 studies that explored a variety of interventions for chronic dyspnea. We identified pharmacological interventions (such as oxygen therapy and inhalation treatments) and non-pharmacological approaches (including educational programs, breathing exercises, fluid intake management, body awareness techniques, peer support, emotional intelligence training, and the use of web applications). Those interventions empower patients, improve their ability to fulfill life roles, mitigate emotional distress, and improve overall quality of life. Nursing care can be crucial in enabling individuals to achieve independence and autonomy in self-care. Conclusions Promoting self-management for chronic dyspnea in complex chronic patients requires a holistic approach, encompassing multidisciplinary interventions, individualized self-care education, peer engagement, and technological support. Current research on self-management inadequately addresses interventions targeting patient behaviour change. It highlights the need to delve deeper into the self-management process. Further research is needed to expand the evidence base and refine these interventions.

Huang YC, Dong Y, Tang CM, Shi Y, Pang J. Mortality and disability risk among older adults unable to complete grip strength and physical performance tests: a population-based cohort study from China. BMC Public Health 2024; 24:797. [PMID: 38481165 PMCID: PMC10938679 DOI: 10.1186/s12889-024-18258-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 03/03/2024] [Indexed: 03/17/2024] Open
Abstract
BACKGROUND The link between low grip strength, diminished physical performance, and adverse health outcomes in older adults has been well-established. However, the impact of older adults who cannot complete these tests on disability and mortality rates remains unexplored without longitudinal study. METHODS We collected data from the China Health and Retirement Longitudinal Study (CHARLS). Participants aged 60-101 were enrolled at baseline. We analyzed the prevalence of populations unable to complete handgrip strength (HGS), gait speed (GS), and five times chair stand test (FTCST). Completing risk models were used to estimate the risk of mortality and disability over seven years. RESULTS A total of 3,768 participants were included in the analysis. The percentage of older adults unable to complete the GS and FTCST tests increased notably with age, from 2.68 to 8.90% and 2.60-20.42%, respectively. The proportion of older people unable to perform the HGS was relatively stable, ranging from 1.40 to 3.66%. Compared to older adults who can complete these tests, those who cannot perform FTCST face a significantly higher risk of mortality, with 49.1% higher risk [hazard ratio (HR) = 1.491, 95% CI = 1.156, 1.922; subdistribution hazard ratio (SHR) = 1.491, 95%CI = 1.135,1.958)]. Participants who were unable to complete the GS test had a higher risk of developing ADL disability, regardless of whether they were compared to the lowest-performing group (HR = 1.411, 95%CI = 1.037,1.920; SHR = 1.356, 95%CI = 1.030,1.785) or those who can complete the GS (HR = 1.727, 95%CI = 1.302,2.292; SHR = 1.541, 95%CI = 1.196,1.986). No statistically significant difference in the risk of developing ADL disability among older adults who were unable to complete the HGS test compared with either the poorest performing group (HR = 0.982, 95% CI = 0.578, 1.666; SHR = 1.025, 95% CI = 0.639, 1.642) or those who were able to complete the HGS test (HR = 1.008, 95% CI = 0.601, 1.688; SHR = 0.981, 95% CI = 0.619, 1.553). The risk of all-cause mortality was not significantly different for older adults who were unable to complete the HGS test compared to those with the worst performance (HR = 1.196, 95%CI = 0.709-2.020; SHR = 1.196, 95%CI = 0.674, 2.124) or those who were able to complete the test (HR = 1.462, 95%CI = 0.872-2.450; SHR = 1.462, 95%CI = 0.821,2.605). CONCLUSION The risks of adverse events faced by older adults unable to complete the tests vary, indicating the necessity for future research to conduct separate analyses on this high-risk population.

Longitudinal Changes in Left Ventricular Diastolic Function in Late Life: The ARIC Study. JACC Cardiovasc Imaging 2023; 16:1133-1145. [PMID: 37178075 DOI: 10.1016/j.jcmg.2023.02.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 02/21/2023] [Accepted: 02/23/2023] [Indexed: 05/15/2023]
Abstract
BACKGROUND There is limited data regarding longitudinal changes of diastolic function in the very old, who are at the highest risk for heart failure (HF). OBJECTIVES This study aims to quantify intraindividual longitudinal changes of diastolic function over 6 years in late life. METHODS The authors studied 2,524 older adult participants in the prospective community-based ARIC (Atherosclerosis Risk In Communities) study who underwent protocol-based echocardiography at study visits 5 (2011-2013) and 7 (2018-2019). The primary diastolic measures were tissue Doppler e', E/e' ratio, and left atrial volume index (LAVI). RESULTS Mean age was 74 ± 4 years at visit 5 and 80 ± 4 at visit 7, 59% were women, and 24% were Black. At visit 5, mean e'septal was 5.8 ± 1.4 cm/s, E/e'septal 11.7 ± 3.5, and LAVI 24.3 ± 6.7 mL/m2. Over a mean of 6.6 ± 0.8 years, e'septal decreased by 0.6 ± 1.4 cm/s, E/e'septal increased by 3.1 ± 4.4, and LAVI increased by 2.3 ± 6.4 mL/m2. The proportion with 2 or more abnormal diastolic measures increased from 17% to 42% (P < 0.001). Compared with participants free of cardiovascular (CV) risk factors or diseases at visit 5 (n = 234), those with prevalent CV risk factors or diseases but without prevalent or incident HF (n = 2,150) demonstrated greater increases in E/e'septal and LAVI. Increases of E/e'septal and LAVI were both associated with the development of dyspnea between visits in analyses adjusted for CV risk factors. CONCLUSIONS Diastolic function generally deteriorates over 6.6 years in late life, particularly among persons with CV risk factors, and is associated with development of dyspnea. Further studies are necessary to determine if risk factor prevention or control will mitigate these changes.

[PMID: 36929105 DOI: 10.1111/jgs.18326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 02/13/2023] [Accepted: 02/14/2023] [Indexed: 03/18/2023]
Abstract
Breathlessness is common among older adults, but it is often hidden as "normal aging "or considered narrowly as a symptom of cardio-respiratory diseases. Studies on breathlessness in older adults are mostly focused on specific diseases, whereas older adults are characterized by multimorbidity and multi-system age-related impairments. This article aims to provide an overview of what is known so far on breathlessness in the general population of older adults and identify areas for further research. Research shows that breathlessness in older adults is a multifactorial geriatric condition, crossing the borders of system-based impairments and diseases, and a valuable independent prognostic indicator for adverse outcomes. Further research needs to investigate (1) the multi-factorial mechanisms of breathlessness in community-dwelling older adults including the role of respiratory sarcopenia; (2) the influence of affective and cognitive changes of older age on the perception and report of breathlessness; (3) the best way to assess and use breathlessness for risk prediction of adverse outcomes in general geriatric assessments; and (4) the most appropriate multi-modal rehabilitation interventions and their outcomes. Clinicians need to shift their approach to dyspnea from a disease symptom to a multifactorial geriatric condition that should be proactively searched for, as it identifies higher risk for adverse outcomes, and can be addressed with evidence-based interventions that can improve the quality of life and may reduce the risk of adverse outcomes in older adults.

[PMID: 35508002 PMCID: PMC9671253 DOI: 10.1590/1516-3180.2021.0237.r2.27072021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Accepted: 07/27/2021] [Indexed: 11/21/2022] Open
Abstract
CONTEXT Dyspnea is a symptom present in several chronic diseases commonly seen among older adults. Since individuals with dyspnea tend to stay at rest, with consequently reduced levels of physical activity, they are likely to be at greater risk of developing frailty, especially at older ages. DESIGN AND SETTING Cross-sectional study at community level, Brazil. OBJECTIVE To analyze the relationships between self-reported dyspnea, health conditions and frailty status in a sample of community-dwelling older adults. METHOD Secondary data from the follow-up of the Frailty in Brazilian Elderly (FIBRA) study, involving 415 community-dwelling older adults (mean age: 80.3 ± 4.68 years), were used. The variables analyzed were sociodemographic characteristics, reported dyspnea, clinical data and frailty phenotype. Associations between dyspnea and other variables (age, sex, education and body mass index) were verified through the crude (c) and adjusted (a) odds ratios. RESULTS The prevalence of dyspnea in the entire sample was 21.0%. Dyspnea was more present in individuals with pulmonary diseases, heart disease, cancer and depression. Older adults with multimorbidities (adjusted odds ratio, ORa = 2.91; 95% confidence interval, CI = 1.41-5.99) and polypharmacy (ORa = 2.02; 95% CI = 1.15-3.54) were more likely to have dyspnea. Those who reported dyspnea were 2.54 times more likely to be frail (ORa = 2.54; 95% CI = 1.08-5.97), and fatigue was their most prevalent phenotype component. CONCLUSION Dyspnea was associated with different diseases, multimorbidities, polypharmacy and frailty. Recognizing the factors associated with dyspnea may contribute to its early identification and prevention of its negative outcomes among older adults.

Effect of pursed-lip breathing and forward trunk lean positions on regional chest wall volume and ventilatory pattern in older adults: An observational study. Medicine (Baltimore) 2022; 101:e28727. [PMID: 35089245 PMCID: PMC8797477 DOI: 10.1097/md.0000000000028727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Accepted: 01/12/2022] [Indexed: 01/05/2023] Open
Abstract
ABSTRACT Pursed-lip breathing (PLB) and forward trunk lean posture (FTLP) are commonly used to relieve dyspnea and improve ventilation in a rehabilitation program. However, their effect on chest wall volumes and movements in older adults without chronic obstructive pulmonary disease has never been investigated. This observational study aimed to identify the effect of combined PLB and FTLP on total and regional chest wall volumes, ventilatory pattern, and thoracoabdominal movement using in older adults. It was hypothesized that the combined PLB with FTLP would result in the highest chest wall volumes among the experimental tasks. Twenty older adults performed 2 breathing patterns of quiet breathing (QB) and PLB during a seated upright (UP) position and FTLP. An optoelectronic plethysmography system was used to capture the chest wall movements during the 4 experimental tasks. Tidal volume (VT) was separated into pulmonary ribcage, abdominal ribcage, and abdomen volume. The changes in anterior-posterior (AP) and medial-lateral (ML) chest wall diameters at 3 levels were measured and used to identify chest wall mechanics to improve chest wall volumes. The PLB significantly improved ventilation and chest wall volumes than the QB (P < .05). VT of pulmonary ribcage, VT of abdominal ribcage, and VT were significantly higher during the PLB + UP (P < .05) and during the PLB + FTLP (P < .01) as compared to those of QB performed in similar body positions. However, there was no significant in total and regional lung volumes between the PLB + UP and the PLB + FTLP. The AP diameter changes at the angle of Louis and xiphoid levels were greater during the PLB + UP than the QB + UP and the QB + FTLP (P < .01). The AP diameter changes at the umbilical level and the ML diameter changes at the xiphoid level were significantly larger during the PLB + FTLP than the QB + FTLP and the QB + UP (P < .05). The ML diameter changes at the umbilical level were significantly greater during the PLB + FTLP than the QB + UP (P < .05). However, no significant difference in the relative regional chest wall volumes and phase angle among the experimental tasks (P > .05). In conclusion, a combined PLB performed in an FTLP or UP sitting could be used as a strategy to improve chest wall volumes and ventilation in older adults.

Abstract
Introduction: To identify factors predictive of falls and enable appropriate management of fall risk it is necessary to understand the behaviour and health conditions of older adults living in nursing homes. Objective: This study had two main objectives. The first was to find significant predictors for falls in older adults living in nursing homes. The second main goal was to build a predictive model to find the best predictors for falls. Methods: Out of 56 nursing homes with the same legal statute, 25 agreed to participate. The sample was randomly selected and only the independent or slight/moderately dependent participants were included in the study (n = 325). Results: There was a mean of 1.47 ± 0.99 falls (range from 1 to 7) per resident in nursing homes. By using the t test and odds ratio analysis, ten factors related to falls were identified. Through the binary logistic regression, a model was tested identifying four robust predictors: static balance, resorting to emergency services, polypharmacy, and an independent self-care profile. Conclusions: The present study replicated the main results of contemporary research on the risk factors of falls. More importantly, it suggests that the self-care profile model should be taken into account in future studies and early interventions. It is crucial to implement preventive measures consistent with safer environments and to establish an individual plan for integrated activities according to older adults’ health needs.

Abstract
To assess to what extent left atrial (LA) structure and function are associated with non-specific heart failure symptoms, so that patients were classified as HF stage A and B. Mechanisms underlying the transition to overt HF in patients with stage A and B HF are unclear. Consecutive outpatients undergoing echocardiography and clinical evaluation and classified as HF stage A and B with preserved left ventricular ejection fraction (LVEF) were included. The association between LA measures [volume (LAVi), peak longitudinal-(PALS), contraction-(PACS) and conduit-strain] and non-specific HF symptoms was assessed using adjusted logistic regression analyses. The incremental value of atrial myopathy in symptoms prediction on top of clinical or echocardiographic confounders was assessed through ROC curves analyses. The cohort comprehended 185 patients (63 ± 16 years, 47% women) of whom 133 (72%) were asymptomatic, and 52 (28%) reported non-specific HF symptoms. After adjustment for clinical and echocardiographic confounders for HF symptoms, LAVi, PALS and PACS were associated with symptoms (p < 0.05). Among echocardiographic variables, only LA parameters were significantly associated with symptoms on top of clinical confounders (for LAVi OR [95% CI] 1.56 [1.21–2.00], p < 0.0001; for PALS 1.45 (1.10–1.91), p = 0.0009; for PACS 2.10 [1.33–3.30], p = 0.002). After adjustment for age, hypertension and COPD or E/E′, LV mass-i and mitral ERO, atrial myopathy added predictive value for symptoms presence compared to the clinical variables or echocardiographic parameters described (AUC increase 0.80 to 0.88, p = 0.004, and 0.79 to 0.84, p = 0.06, respectively). In patients with HF stages A–B and preserved LVEF, measures of LA structure and function were associated with non-specific HF symptoms. A comprehensive LA remodeling evaluation may help clinicians in the appropriate identification of overt HF.

Abstract
Breathlessness is a common and distressing symptom in older adults and an independent predictor of adverse outcomes and yet its multidimensional assessment has not been validated in older adults. We apply and validate the Multidimensional Dyspnoea Profile (MDP) in a sample of adults 75 years and older in Belgium. Breathlessness was rated with the MDP, the modified Borg Dyspnoea Scale (mBDS), the Short Physical Performance Battery (SPPB, a numerical rating scale for intensity and unpleasantness both before and after exertion), as well as with the Medical Research Council (MRC) Dyspnoea Scale. The Hospital Anxiety and Depression Scale (HADS) assessed the affective status. Factor structure was analysed with exploratory principal components analysis, internal consistency with Cronbach's alpha and concurrent validity with Spearman's correlation coefficients with other breathlessness scales, HADS and SPPB scores. In 96 participants (mean age 85 years; 34% men) who rated breathlessness at both assessment points, exploratory principal components analysis identified two components: Immediate Perception (IP) and Emotional Reaction (ER), explaining most of the MDP item variance (65.37% before and 71.32% after exertion). Internal consistency was moderate to high for MDP-IP (Cronbach's alpha = 0.86 before and 0.89 after exertion) and MDP-ER (Cronbach's alpha = 0.89 before and 0.91 after exertion). The correlation patterns of MDP-IP and MDP-ER with other tests confirmed concurrent validity. The domain structure, reliability and concurrent validity of MDP for breathlessness before and after exertion were confirmed in a sample of adults 75 years and older, supporting its use and further research for the multidimensional profiling of breathlessness in older adults. Domain structure, reliability and concurrent validity of the MDP were confirmed in a sample of adults aged ≥75 years before and after exertion, supporting its use for the multidimensional assessment of breathlessness in this age grouphttps://bit.ly/3emiNRW

Prevalence and factors associated with poor performance in the 5-chair stand test: findings from the Cognitive Function and Ageing Study II and proposed Newcastle protocol for use in the assessment of sarcopenia. J Cachexia Sarcopenia Muscle 2021; 12:308-318. [PMID: 33463015 PMCID: PMC8061374 DOI: 10.1002/jcsm.12660] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 11/08/2020] [Accepted: 11/24/2020] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND Poor performance in the 5-chair stand test (5-CST) indicates reduced lower limb muscle strength. The 5-CST has been recommended for use in the initial assessment of sarcopenia, the accelerated loss of muscle strength and mass. In order to facilitate the use of the 5-CST in sarcopenia assessment, our aims were to (i) describe the prevalence and factors associated with poor performance in the 5-CST, (ii) examine the relationship between the 5-CST and gait speed, and (iii) propose a protocol for using the 5-CST. METHODS The population-based study Cognitive Function and Ageing Study II recruited people aged 65 years and over from defined geographical localities in Cambridgeshire, Newcastle, and Nottingham. The study collected data for assessment of functional ability during home visits, including the 5-CST and gait speed. We used multinomial logistic regression to assess the associations between factors including the SARC-F questionnaire and the category of 5-CST performance: fast (<12 s), intermediate (12-15 s), slow (>15 s), or unable, with slow/unable classed as poor performance. We reviewed previous studies on the protocol used to carry out the 5-CST. RESULTS A total of 7190 participants aged 65+ from the three diverse localities of Cognitive Function and Ageing Study II were included (54.1% female). The proportion of those with poor performance in the 5-CST increased with age, from 34.3% at age 65-69 to 89.7% at age 90+. Factors independently associated with poor performance included positive responses to the SARC-F questionnaire, physical inactivity, depression, impaired cognition, and multimorbidity (all P < 0.005). Most people with poor performance also had slow gait speed (57.8%) or were unable to complete the gait speed test (18.4%). We found variation in the 5-CST protocol used, for example, timing until a participant stood up for the fifth time or until they sat down afterwards. CONCLUSIONS Poor performance in the 5-CST is increasingly common with age and is associated with a cluster of other factors that characterize risk for poor ageing such as physical inactivity, impaired cognition, and multimorbidity. We recommend a low threshold for performing the 5-CST in clinical settings and provide a protocol for its use.

A comprehensive analysis of factors related to lung function in older adults: Cross-sectional findings from the Canadian Longitudinal Study on Aging. Respir Med 2020; 173:106157. [PMID: 33010732 DOI: 10.1016/j.rmed.2020.106157] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2020] [Revised: 09/02/2020] [Accepted: 09/15/2020] [Indexed: 12/15/2022]
Abstract
Maintenance of lung function is an often underappreciated, yet critical component of healthy aging. Given the unprecedented shift in the average age of Canadians over the next half century, it will be important to investigate the determinants of lung function in the elderly. In the following study, we estimated the association between lung function and a broad array of factors related to sociodemographics, lifestyle, chronic medical conditions and psychosocial factors in older adults aged 45-86 years old using cross-sectional data from the Canadian Longitudinal Study of Aging (n = 21,338). In addition to examining the entire cohort, we also performed stratified analyses within men/women, adults aged 45-64/65+, and healthy/comorbid. In multivariable regression, our explanatory factors (excluding age, sex, height and ethnicity) were able to explain 17% and 11% of the total variance in FEV1 and FEV1/FVC, respectively. Notable and significant contributions were observed for respiratory disease, smoking, obesity, income, and physical activity, while psychosocial factors mainly exhibited non-significant associations. Generally, these associations were stronger for males than females, and adults 65 and older as compared to those aged 45-64. Our findings indicate that there are pervasive and generally under-recognized sociodemographic and lifestyle factors that exhibit significant associations with FEV1 and FEV1/FVC in older adults. While implication of causality in these relationships is not possible due to the cross-sectional nature of the study, future work aiming to investigate determinants of lung health in older adults may choose to target these factors, given that many are modifiable.

Antihypertensive medications and physical function in older persons. Exp Gerontol 2020; 138:111009. [PMID: 32593771 DOI: 10.1016/j.exger.2020.111009] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 05/18/2020] [Accepted: 06/18/2020] [Indexed: 01/08/2023]
Abstract
BACKGROUND To further inform benefits and risks of medications on physical function in aging populations, we have evaluated the associations of antihypertensive (antiHTN) class and number used with skeletal muscle function, mobility, sedentary time, and symptoms in older persons. METHODS Using baseline data from the Lifestyle Interventions and Independence in Elder (LIFE) study (N = 1567, mean age 78.9 years) and multivariable models, we evaluated cross-sectional associations of antiHTN class and number used with physical measures and symptom questionnaires. AntiHTN class included diuretics, angiotensin converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB), calcium channel blockers (CCB), and beta blockers (BB). Physical measures included respiratory muscle weakness (maximal inspiratory pressure), grip weakness (dynamometer), impaired lower extremity proximal muscle strength (chair stands), impaired balance (three-stage test), slow gait (400 m walk), mobility impairment (Short Physical Performance Battery), and high sedentary time (accelerometry). Symptoms included dyspnea and fatigue. Covariates included clinical characteristics and non-antiHTNs. RESULTS Use of any antiHTN was highly prevalent (n = 1248 [79.6%]). In the antiHTN subgroup, each antiHTN class was well represented (ranging 36.6%-62.7%) and included use of three or more antiHTNs (32.0%). In adjusted models, the only statistically significant associations were use of BB and three or more antiHTNs with high sedentary time: odds ratios (95% confidence intervals) 1.44 (1.12, 1.85) and 1.52 (1.04, 2.23), respectively. CONCLUSION Use of BB and three or more antiHTNs yielded 44% and 52% increased odds of accelerometry-defined high sedentary time, respectively. Notably, high sedentary time is a risk factor for adverse health outcomes. Thus, future work should evaluate whether high sedentary time mitigates benefits or increases risks, regarding antiHTN use in aging populations.

SAO PAULO MED J 2020; 138:112-117. [PMID: 32294715 PMCID: PMC9662837 DOI: 10.1590/1516-3180.2019.0428.r1.09122019] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2019] [Accepted: 12/09/2019] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND Dyspnea and poorer physical performance are conditions that may be related and be present among the elderly. However, few studies have evaluated associations between these variables. OBJECTIVE To determine whether there is an association between dyspnea and physical performance among community-dwelling older adults of both sexes (age 60 years and over). DESIGN AND SETTING Cross-sectional study conducted in the city of Macapá, state of Amapá, Brazil. METHODS Socioeconomic and health data were collected using a structured form. Frailty syndrome was assessed based on the frailty phenotype proposed by Fried et al. Dyspnea was measured using the modified Medical Research Council (mMRC) scale and physical performance was measured using the Short Physical Performance Battery (SPPB). Data were analyzed using a linear regression model. RESULTS A total of 411 subjects (70.15 ± 7.25 years) were evaluated, most of them females (66.4%). It was observed from the mMRC scale that 30.9% (n = 127) of the subjects had some dyspnea symptoms: grade 1 was most frequent. The physical performance score from the SPPB was 9.22 ± 2.01. Higher dyspnea scores were associated with poor physical performance, both in the crude analysis (β = -0.233; P = 0.028) and after adjustment for frailty condition (β = -0.148; P = 0.002) and for the socioeconomic and health variables (age, sex, number of diseases, smoking habit and frailty status) (β = -0.111; P = 0.025). CONCLUSION Higher dyspnea score was independently associated with poor physical performance among community-dwelling older adults.

Abstract
Background/Aim: Dyspnoea represents a subjective feeling of laboured breathing of different intensity. The aim of this study was to determine how often patients come with dyspnoea to a local Emergency Department of the Primary Healthcare Centre (EDPHC) and to analyse the assumed aetiology, diagnostics and therapy of the dyspnoeic patients. Methods: The records of the EDPHC of the City of Banja Luka for the period between 1 October 2019 to 31 December 2019 of all patients older than 15 years of age that have reported laboured breathing were identified and analysed. Following parameters were recorded: age, gender, diagnostics performed, administered therapy, whether the patient was examined in the field or in the ambulance, as well as whether the patient was referred to a hospital (Cardiology, Pulmonology or another department) or not. Results: Laboured breathing was reported by 665 patients. Out of this number, 108 patients were examined by their family doctor, 407 patients in EDPHC ambulance and 150 patients in the field. The average age of the patient was 61.03 ± 19.17, with an equal distribution in males and females. The aetiology of dyspnoea was cardiac and pulmonary in one-third of patients each, whereas the diagnosis in the other patients was versatile, from anxiety disorders, musculoskeletal diseases and active malignancy to unspecified chest pain that could not receive a definitive diagnosis. One half of the patients (N = 261 or 46.86 %) was completely taken care of in the ambulance or in the field, 199 (35.73 %) patients were sent to a cardiologist, 87 (15.62 %) to a pulmonologist and 10 (1.80 %) of patients to another specialist. Referral to hospital was registered more often in men (ch2 = 9.195, p = 0.027), elderly (ch2 = 53.29, p < 0.001), people with lower peripheral oxygen saturation (SpO2 ) (ch2 = 120.61, p < 0.001) and people with significant deviation of normal blood pressure values (ch2 = 120.61, p < 0.001). Conclusion: Dyspnoea can be caused by an array of different diseases and more than one diagnostic method is necessary to confirm/exclude any of the most common causes of dyspnoea. A broader diagnostical palette in ED would be preferred for purposes of ascertaining a timely diagnosis.

Abstract
BACKGROUND Commonly used thresholds for staging FEV1 have not been evaluated as standalone spirometric predictors of death in older persons. Specifically, the proportion of deaths attributed to a reduced FEV1, when staged by commonly used thresholds in L, percent of predicted (% pred), and Z scores, has not been previously reported. METHODS In 4,232 white persons ≥ 65 y old, sampled from the Cardiovascular Health Study, FEV1 was stratified as stage 1 (FEV1 ≥ 2.00 L, ≥80% pred, and Z score ≥-1.64), stage 2 (FEV1 1.50-1.99 L, 50-79%pred, and Z score -2.55 to -1.63), and stage 3 (FEV1 < 1.50 L, < 50% pred, and Z score < -2.55). Notably, a Z score threshold of -1.64 defines normal-for-age lung function as the lower limit of normal (ie, 5th percentile of distribution), and accounts for differences in age, sex, height, and ethnicity. Next, adjusted odds ratios and average attributable fractions for 10-y all-cause mortality were calculated, comparing FEV1 stages 2 and 3 against stage 1, expressed in L, % pred, and Z scores. The average attributable fraction estimates the proportion of deaths attributed to a predictor by combining the prevalence of the predictor with the relative risk of death conferred by that predictor. RESULTS FEV1 stage 2 and 3 in L, % pred, and Z scores yielded similar adjusted odds ratios of death: 1.40-1.51 for stage 2 and 2.35-2.66 for stage 3. Conversely, FEV1 stages 2 and 3 in L, % pred, and Z scores differed in prevalence: 12.8-28.6% for stage 2 and 6.4-17.5% for stage 3, and also differed in the adjusted average attributable fraction for death: 3.2-6.4% for stage 2 and 4.5-9.1% for stage 3. CONCLUSIONS In older persons, the proportion of deaths attributed to a reduced FEV1 is best stratified by Z score staging thresholds because these yield a similar relative risk of death but a more age- and sex-appropriate prevalence of FEV1 stage.

Abstract
OBJECTIVE To examine the epidemiology and key demographic and clinical correlates of patient-reported hypersomnia in persons with advanced age. DESIGN Cross-sectional design. SETTING Community. PARTICIPANTS A total of 357 community-dwelling persons from the Yale Precipitating Events Project with a mean age of 84.2 years (range = 78-102 years). MEASUREMENTS We studied patient-reported hypersomnia, defined categorically by an Epworth Sleepiness Scale (ESS) score of 10 or greater; as well as the severity of hypersomnia symptoms, defined continuously by an ESS score range of 0 to 24 (higher scores denote greater sleepiness). In multivariable regression models, we examined cross-sectional associations between key correlates and ESS score, expressed as categorical and continuous variables. Key correlates included: demographics, education, smoking status, body mass index, self-reported medical conditions, Center for Epidemiologic Studies Depression score, Mini-Mental State Examination score, Physical Activity Scale for the Elderly, restless legs syndrome (RLS), self-reported sleep-disordered breathing (SDB), medications, and Insomnia Severity Index. RESULTS Mean ESS score for all participants was 6.4. Patient-reported hypersomnia (ESS score ≥10) was established in 82 participants (23.0%)-their mean ESS score was 13.0. In multivariable models, male sex, nonwhite race, arthritis, depressive symptoms, low physical activity, RLS, SDB, central nervous system depressant medications, and insomnia severity were cross-sectionally associated with patient-reported hypersomnia (higher adjusted odds ratios, ranging from 1.93-2.86) and/or with the severity of hypersomnia symptoms (higher ESS scores, ranging from 0.11-2.86 points). CONCLUSION Patient-reported hypersomnia was prevalent in a sample of community-dwelling persons with advanced age. In addition, based on cross-sectional associations with the ESS score, key demographic and clinical characteristics were identified that may inform screening strategies for hypersomnia in advanced age.

Heterogeneity of healthy aging: comparing long-lived families across five healthy aging phenotypes of blood pressure, memory, pulmonary function, grip strength, and metabolism. GeroScience 2019; 41:383-393. [PMID: 31332674 PMCID: PMC6815318 DOI: 10.1007/s11357-019-00086-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Accepted: 07/08/2019] [Indexed: 02/04/2023] Open
Abstract
Five healthy aging phenotypes were developed in the Long Life Family Study to uncover longevity pathways and determine if healthy aging across multiple systems clustered in a subset of long-lived families. Using blood pressure, memory, pulmonary function, grip strength, and metabolic measures (body mass index, waist circumference and fasting levels of glucose, insulin, triglycerides, lipids, and inflammatory markers), offspring were ranked according to relative health using gender-, age-, and relevant confounder-adjusted z-scores. Based on our prior work, families met a healthy aging phenotype if ≥ 2 and ≥ 50% of their offspring were exceptionally healthy for that respective phenotype. Among 426 families, only two families met criteria for three healthy aging phenotypes and none met criteria for four or more healthy aging phenotypes. Using Spearman correlation, the proportion of offspring within families with exceptionally healthy pulmonary function was correlated with the proportion of offspring within families with exceptional strength (r = 0.19, p = 0.002). The proportion of offspring within families meeting the healthy blood pressure and metabolic phenotypes were also correlated (r = 0.14, p = 0.006), and more families were classified as meeting healthy blood pressure and metabolic phenotypes (Kappa = 0.10, p = 0.02), as well as the healthy pulmonary and blood pressure phenotypes than expected by chance (Kappa = 0.09, p = 0.03). Other phenotypes were weakly correlated (|r| ≤ 0.07) with low pairwise agreement (Kappa ≤ 0.06). Among these families selected for familial longevity, correspondence between healthy aging phenotypes was weak, supporting the heterogeneous nature of longevity and suggesting biological underpinnings of each individual phenotype should be examined separately to determine their shared and unique determinants.

Abstract
Importance Undifferentiated dyspnea is common in late life, but the relative contribution of subclinical cardiac dysfunction is unknown. Impairments in cardiac structure and function may be characteristics of undifferentiated dyspnea in elderly people, providing potential insights into occult heart failure (HF). Objective To quantify the association of undifferentiated dyspnea with cardiac dysfunction after accounting for other potential contributors. Design, Setting, and Participants This cross-sectional study used data from Atherosclerosis Risk in Communities study participants 65 years and older who attended the fifth study visit (from 2011 to 2013) and had not been diagnosed with HF, chronic obstructive pulmonary disease, morbid obesity, or severe kidney disease. Analyses were conducted from October 2017 to June 2018. Exposures Dyspnea measured using the modified Medical Research Council scale, with a score less than 2 classified as none to mild and a score of 2 or more classified as moderate to severe. Main Outcomes and Measures Using multivariable logistic regression, the association of undifferentiated dyspnea was defined using cardiac structure, systolic and diastolic function, pulmonary pressure (echocardiography), pulmonary function (spirometry), glomerular filtration rate, hemoglobin, body mass index, depression, and physical performance. The population-attributable risk was calculated for each dysfunction metric. Results Among 4342 participants (mean [SD] age, 75.9 [5.0] years; 2533 [58.3%] women), 1173 (27.0%) had undifferentiated dyspnea. Moderate to severe dyspnea was present in 574 participants (13.2%) and was associated with left ventricular (LV) hypertrophy (odds ratio [OR], 1.53; 95% CI, 1.25-1.87; P < .001) and LV diastolic (OR, 1.46; 95% CI, 1.20-1.78; P < .001) and systolic (OR, 1.28; 95% CI, 1.05-1.56; P = .02) dysfunction. Moderate to severe dyspnea was also associated with obstructive (OR, 1.59; 95% CI, 1.28-1.99; P < .001) and restrictive (OR, 2.56; 95% CI, 1.99-3.27; P < .001) findings on spirometry, renal impairment (OR, 1.32; 95% CI, 1.08-1.61; P = .01), anemia (OR, 1.72; 95% CI, 1.39-2.12; P < .001), lower (OR, 2.77; 95% CI, 2.18-3.51; P < .001) and upper (OR, 1.82; 95% CI, 1.49-2.23; P < .001) extremity weakness, depression (OR, 3.01; 95% CI, 2.24-4.25; P < .001), and obesity (OR, 2.35; 95% CI, 1.95-2.83; P < .001). After accounting for these, moderate to severe dyspnea was associated with LV hypertrophy (OR, 1.30; 95% CI, 1.01-1.67; P = .04) and was not associated with systolic or diastolic function. In contrast, in the fully adjusted model, other organ system measures were associated with dyspnea, except for glomerular filtration rate and grip strength. The population-attributable risk of dyspnea associated with obesity alone was 22.6% compared with 5.8% for LV hypertrophy. Conclusions and Relevance Undifferentiated dyspnea is multifactorial in older adults, and this study showed an association with obesity. When accounting for other relevant organ systems, cardiovascular function poorly discriminated those with vs those without dyspnea. Therefore, dyspnea should not be assumed to represent occult HF in this population.

Abstract
Approximately half of the patients with signs and symptoms of heart failure have a left ventricular ejection fraction that is not markedly abnormal. Despite the historically initial surprise, heightened risks for heart failure specific major adverse events occur across the broad range of ejection fraction, including normal. The recognition of the magnitude of the problem of heart failure with preserved ejection fraction in the past 20 years has spurred an explosion of clinical investigation and growing intensity of informative outcome trials. This article addresses the historic development of this component of the heart failure syndrome, including the epidemiology, pathophysiology, and existing and planned therapeutic studies. Looking forward, more specific phenotyping and even genotyping of subpopulations should lead to improvements in outcomes from future trials.

Abstract
Introduction: Spirometry, the most common lung function test, is used to evaluate individuals with respiratory complaints or known respiratory disease. However, its underutilization and the misinterpretation of its parameters are causes for concern. Areas covered: This review describes new spirometry-derived metrics, new reference equations, recent recommendations for presentation of results, recent spirometry-based prevalence studies, and technological advances in spirometry equipment. Expert opinion: The underutilization of spirometry can be overcome by increasing access to portable, hand-held, and user-friendly spirometers, together with strategies that increase awareness of the importance of spirometry. New metrics derived from spirometry, together with traditional spirometric criteria, can identify individuals with structural lung disease and respiratory morbidity. Some problems with the reference equations were solved by the Global Lung Function Initiative (GLI), which covers a wider age range and more ethnic groups and provides limits of normality using the z-score. Despite these advantages, the GLI equations lack data from large populations (especially those from Africa, South Asia, and Latin America) and greater representation of older people. Another disadvantage attributed to the GLI is the lack of predicted values for peak expiratory flow and other airflows, limiting the interpretation of the maximal expiratory flow-volume curve.

Abstract
PURPOSE Upper extremities play an important role in performing of many activities of daily living. Physical and pathological changes limit upper extremity functions in older adults with chronic obstructive pulmonary disease (COPD). Although the 6-minute pegboard and ring test (6PBRT) is a reliable and commonly used method for the assessment of unsupported upper-extremity exercise capacity in patients with COPD, there is lack of evidence about the possible determinants of the 6PBRT score. The study aimed to investigate the possible determinants of the 6PBRT in older adults with COPD. METHODS Fifty-two older adults (age ≥ 65 years) with stable COPD and 23 age-matched healthy older adults participated in this study. Demographic characteristics, unsupported upper-extremity exercise capacity, pulmonary function, functional exercise capacity, disease related symptoms, peripheral and respiratory muscle strength were evaluated. Stepwise multiple linear regression analysis was used to investigate the possible determinants of the 6PBRT score. RESULTS The 6PBRT score was significantly higher in healthy participants compared with those with COPD (p = 0.024). In participants with COPD, shoulder flexor muscle strength, age and functional exercise capacity were significant and independent predictors of the unsupported upper-extremity exercise capacity with explaining 55.4% of the variance. CONCLUSIONS This study suggests that shoulder flexor muscle strength, age and functional exercise capacity are independent determinants of the unsupported upper-extremity exercise capacity assessed by the 6PBRT in older adults with COPD.

Abstract
PURPOSE OF REVIEW Breathlessness is a high-volume problem with 10% of adults experiencing the symptom daily placing a heavy burden on the health and wider economy. As it worsens, they enter the specialist and hospital-based symptom services where costs quickly escalate and people may find themselves in a place not of their choosing. For many, their care will be delivered by a disease or organ specialist and can find themselves passing between physicians without coordination for symptom support. General practitioners (GPs) will be familiar with this scenario and can often feel out of their depth. Recent advances in our thinking about breathlessness symptom management can offer opportunities and a sense of hope when the GP is faced with this situation. RECENT FINDINGS Original research, reviews and other findings over the last 12-18 months that pertain to the value that general practice and the wider primary care system can add, include opportunities to help people recognize they have a problem that can be treated. We present systems that support decisions made by primary healthcare professionals and an increasingly strong case that a solution is required in primary care for an ageing and frail population where breathlessness will be common. SUMMARY Primary care practitioners and leaders must start to realize the importance of recognizing and acting early in the life course of the person with breathlessness because its impact is enormous. They will need to work closely with public health colleagues and learn from specialists who have been doing this work usually with people near to the end of life translating the skills and knowledge further upstream to allow people to live well and remain near home and in their communities.

Abstract
Background adults aged 80 and over, a fast growing age-group, with increased co-morbidity and frailty have not been the focus of previous research on dyspnoea. We investigate the correlates of dyspnoea and its association with adverse outcomes in a cohort of adults aged 80 and over. Methods about 565 community-dwelling adults aged 80 and over of the BELFRAIL prospective cohort had assessment of Medical Research Council dyspnoea scale (MRC), forced expiratory volume in 1 s (FEV1), N-terminal pro-brain natriuretic peptide (NT-proBNP), physical performance tests, grip strength, 15 items geriatric depression scale, activities of daily living (ADL), body mass index (BMI) and demographics data. Kaplan-Meier survival curves, Cox and logistic multivariable regression, classification and regression tree (CART) analysis assessed association of dyspnoea (MRC 3-5) with time-to-cardiovascular and all-cause death (5 years), time to first hospitalisation (3 years), new/worsened ADL disability (2 years), and its correlates. Results participants with dyspnoea MRC 3-5 (29.9%) had increased hazard ratios for cardiovascular mortality 2.85 (95% confidence interval 1.93-4.20), all-cause mortality 2.04 (1.58-2.64), first hospitalisation 1.72 (1.35-2.19); and increased odds ratio for new/worsened disability 2.49 (1.54-4.04), independent of age, sex and smoking status. Only FEV1, physical performance, BMI and NT-proBNP (in order of importance) were selected in the tree-based classification model for dyspnoea. Conclusions in a cohort of adults aged 80 and over, dyspnoea was common and an independent predictor of adverse outcomes, with cardio-respiratory and physical performance impairments as key independent correlates. Its routine and comprehensive evaluation in primary care could be very valuable in caring for this age-group.

Abstract
BACKGROUND Spirometric Z-scores from the Global Lung Initiative (GLI) rigorously account for age-related changes in lung function and are thus age-appropriate when establishing spirometric impairments, including a restrictive pattern and air-flow obstruction. However, GLI-defined spirometric impairments have not yet been evaluated regarding associations with static lung volumes (total lung capacity [TLC], functional residual capacity [FRC], and residual volume [RV]) and gas exchange (diffusing capacity). METHODS We performed a retrospective review of pulmonary function tests in subjects ≥40 y old (mean age 64.6 y), including pre-bronchodilator measures for: spirometry (n = 2,586), static lung volumes by helium dilution with inspiratory capacity maneuver (n = 2,586), and hemoglobin-adjusted single-breath diffusing capacity (n = 2,508). Using multivariable linear regression, adjusted least-squares means (adjLSMeans) were calculated for TLC, FRC, RV, and hemoglobin-adjusted single-breath diffusing capacity. The adjLSMeans were expressed with and without height-cubed standardization and stratified by GLI-defined spirometry, including normal (n = 1,251), restrictive pattern (n = 663), and air-flow obstruction (mild, [n = 128]; moderate, [n = 150]; and severe, [n = 394]). RESULTS Relative to normal spirometry, restrictive-pattern had lower adjLSMeans for TLC, FRC, RV, and hemoglobin-adjusted single-breath diffusing capacity (P ≤ .001). Conversely, relative to normal spirometry, mild, moderate, and severe air-flow obstruction had higher adjLSMeans for FRC and RV (P < .001). However, only mild and moderate air-flow obstruction had higher adjLSMeans for TLC (P < .001), while only moderate and severe air-flow obstruction had higher adjLSMeans for RV/TLC (P < .001) and lower adjLSMeans for hemoglobin-adjusted single-breath diffusing capacity (P < .001). Notably, TLC (calculated as FRC + inspiratory capacity) was not increased in severe air-flow obstruction (P ≥ .11) because inspiratory capacity decreased with increasing air-flow obstruction (P < .001), thus opposing the increased FRC (P < .001). Finally, P values were similar whether adjLSMeans were height-cubed standardized. CONCLUSIONS A GLI-defined spirometric restrictive pattern is strongly associated with a restrictive ventilatory defect (decreased TLC, FRC, and RV), while GLI-defined spirometric air-flow obstruction is strongly associated with hyperinflation (increased FRC) and air trapping (increased RV and RV/TLC). Both spirometric impairments were strongly associated with impaired gas exchange (decreased hemoglobin-adjusted single-breath diffusing capacity).
