Redefining the elderly as aged 75 years and older: Proposal from the Joint Committee of Japan Gerontological Society and the Japan Geriatrics Society

Association of Social Isolation and Loneliness With Chronic Low Back Pain Among Older Adults: A Cross-sectional Study From Japan Gerontological Evaluation Study (JAGES)

BACKGROUND

Per the biopsychosocial model, pain, especially chronic low back pain, which often presents with nonspecific pain, requires a comprehensive approach involving social factors. However, the association of social factors, including social isolation and loneliness, with this condition remains unclear. This study examined the cross-sectional association of social isolation and loneliness with chronic low back pain among older adults.

METHODS

We recruited functionally independent older adults through a mail survey in 2019 from the Japan Gerontological Evaluation Study (JAGES). Chronic low back pain was defined as low back pain lasting more than 3 months. Social isolation was identified based on face-to-face and non-face-to-face interactions ("not isolated," "isolated tendency," and "isolated"). Loneliness was assessed using the University of California, Los Angeles Loneliness Scale ("not lonely," "lonely tendency," and "lonely").

RESULTS

Consequently, 21,463 participants were analyzed (mean age: 74.4 years; 51.5% females); 12.6% reported chronic low back pain. Multivariable Poisson regression analysis revealed that loneliness was significantly associated with the likelihood of chronic low back pain; compared with "not lonely", the prevalence ratio (PR) was 1.14 (95% confidence interval [CI], 1.05-1.25) for "lonely tendency" and 1.40 (95% CI, 1.27-1.54) for "lonely." Social isolation was not associated; compared with "not isolated," the PR was 0.96 (95% CI, 0.88-1.05) for "isolated tendency" and 0.99 (95% CI, 0.89-1.10) for "isolated." A positive multiplicative interaction between social isolation and loneliness for chronic low back pain was found.

CONCLUSION

Lonelier individuals were more likely to experience chronic low back pain, and those with loneliness and social isolation were synergistically more likely for this condition.

The aging gastrointestinal tract: Epidemiology and clinical significance of disorders of gut-brain interaction in the older general population

BACKGROUND

Most previous reports on the prevalence of disorders of gut-brain interaction (DGBI) show higher rates in younger individuals. Exceptions are faecal incontinence and functional constipation.

AIM

To compare prevalence rates for 22 DGBI and 24 primary symptoms, by age, using the Rome Foundation Global Epidemiology (RFGES) study dataset.

METHODS

The RFGES dataset enables diagnosis of 22 DGBI among 54,127 participants (≥18 years) in 26 countries. Older age was defined as ≥65 years. We assessed differences between age groups by sex, geographic region, somatisation, abnormal anxiety and depression scores, quality of life (QoL), individual gastrointestinal symptoms and disease severity for irritable bowel syndrome (IBS).

RESULTS

Rates for any DGBI were 41.9% and 31.9% in the <65 and ≥65 age groups, respectively. For all Rome IV diagnoses except faecal incontinence, rates were higher in the younger group. The older group had lower scores for any DGBI by geographic region, non-gastrointestinal somatic symptoms, abnormal anxiety and depression scores, and IBS severity, and better scores for QoL. The mean number of endorsed symptoms and their frequency were higher in the younger group.

CONCLUSIONS

In this large general population study, the prevalence and impact of DGBI, apart from faecal incontinence, were higher in the younger group. Despite this, DGBI rates are still high in absolute terms in the ≥65 age group and necessitate clinical awareness and, perhaps, an age-specific treatment approach.

Comparison of the Incidence of Functional Disability Correlated With Social Participation Among Older Adults in Japan

BACKGROUND

Japan, which has the world's longest life expectancy, has been reporting rejuvenation of physical function among its older adult population. However, evidence for the incidence of functional disability is limited. This study aimed to investigate the comparison in the incidence of functional disability.

DESIGN

We used data from the Japan Gerontological Evaluation Study.

SETTING AND PARTICIPANTS

The participants were 2 nonoverlapping cohorts of 22,522 (2010-2013 cohort) and 26,284 (2016-2019 cohort) individuals aged 65 years and older from 5 municipalities who were followed for 3 years each.

METHODS

The incidence rates of functional disability during the 3-year follow-up period were compared between cohorts. To examine the incident differences between the cohorts, we adjusted for social participation and 9 additional factors that would be expected to improve with social participation using the Weibull survival models adjusting for municipalities as random effects. The analysis was stratified by age groups (65-74 years old and ≥75).

RESULTS

The incidence rate of functional disability per 10,000 person-years decreased from 68.6 (2010-2013 cohort) to 51.4 (2016-2019 cohort) in the 65 to 74 years old group and 380.0 (2010-2013 cohort) to 282.6 (2016-2019 cohort) in the ≥75 group; the hazard ratios (95% CIs) were 0.75 (0.64-0.89) and 0.73 (0.67-0.80), respectively. However, these significant decreases disappeared with adjustments for social participation and additional factors.

CONCLUSIONS AND IMPLICATIONS

The incidence of functional disability decreased in a recent cohort, which may be explained by social participation and possibly related factors. Promoting social participation could contribute to a decreasing incidence of functional disability among older adults.

Association between oral frailty and lower urinary tract symptoms among middle-aged and older adults in community-dwelling individuals: a cross-sectional study

PURPOSE

We assessed the association between oral frailty risk and LUTS among middle-aged and older adults in a community-dwelling population.

METHODS

This cross-sectional study was conducted among 586 subjects aged ≥ 40 years who participated in the Iwaki Health Promotion Project in Hirosaki, Japan. We used the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS) to assess LUTS. LUTS was defined as an IPSS score of 8 or higher or meeting diagnostic criteria for OAB. Oral frailty risk was defined as experiencing two or more of the following: decreased chewing ability, decreased biting force, and dry mouth sensation. Physical performance (10-m gait speed and grip strength) was used for analysis. The association between oral frailty risk and LUTS was examined using multivariate logistic regression analyses.

RESULTS

The study included 218 men and 370 women, of whom 140 had LUTS. The mean age of this cohort was 59 years. Significant differences were observed between the LUTS and non-LUTS groups, including age, hypertension, history of CVD, depressive status, sleep disturbance, and 10 m gait speed. The prevalence of oral frailty risk was significantly higher in the LUTS group than in the non-LUTS group (26% vs. 11%, P < 0.001). Multivariate analysis revealed that age, male gender, and oral frailty risk (odds ratio: 2.67, 95% confidence interval: 1.57-4.51, P < 0.001) were independent factors for LUTS. Moreover, oral frailty risk was an independent factor in both participants aged < 65 years and participants aged ≥ 65 years.

CONCLUSIONS

Oral frailty was independently associated with LUTS.

Comorbidity burden and outcomes after mechanical thrombectomy for large vessel occlusion: A retrospective analysis

OBJECTIVES

Patients with acute ischemic stroke (AIS) often have an accumulation of pre-existing comorbidities, but its clinical impact on outcomes after mechanical thrombectomy (MT) remains unknown. Therefore, we examined whether comorbidity burden before AIS onset could predict clinical outcomes after MT.

METHODS

In this retrospective cohort, we enrolled consecutive patients with community-onset AIS who underwent MT between April 2016 and December 2021. To evaluate each patient's comorbidity burden, we calculated Charlson comorbidity index (CCI), then classified the patients into the High CCI (≥ 3) and the Low CCI (< 3) groups. The primary outcome was a good neurological outcome at 90 days, defined as a modified Rankin scale 0-2 or no worse than the previous daily conditions. All-cause mortality at 90 days and hemorrhagic complications after MT were also compared between the two groups. We estimated the odds ratios and their confidence intervals using a multivariable logistic regression model.

RESULTS

A total of 388 patients were enrolled, of whom 86 (22.2%) were classified into the High CCI group. Patients in the High CCI group were less likely to achieve a good neurological outcome (adjusted odds ratio of 0.26 [95% confidence interval, 0.12-0.58]). Moreover, symptomatic intracranial hemorrhage was more common in the High CCI (14.0% vs. 4.6%; adjusted odds ratio, 4.10 [95% confidence interval, 1.62-10.3]).

CONCLUSIONS

Comorbidity burden assessed by CCI was associated with clinical outcomes after MT. CCI has the potential to become a simple and valuable tool for predicting neurological prognosis among patients with AIS and MT.

Robot-assisted partial nephrectomy in younger versus older adults with renal cell carcinoma: a propensity score-matched analysis

PURPOSE

Our study aimed to compare the surgical outcomes of robot-assisted partial nephrectomy (RAPN) between younger and older patients after adjusting for their background differences. We particularly assessed RAPN outcomes and safety in older patients.

METHODS

We retrospectively evaluated 559 patients clinically diagnosed with T1 renal cell carcinoma (RCC) and treated with RAPN between 2013 and 2022 at five institutions in Japan. The patients were classified into two groups according to their age during surgery (younger group: < 75 years, older group: ≥ 75 years). Propensity score matching (PSM) was performed to adjust for the differences in the backgrounds between younger and older patients, and surgical outcomes were compared.

RESULTS

Among the 559 patients, 422 (75.5%) and 137 (24.5%) were classified into the younger and older groups, respectively; 204 and 102 patients from the younger and older groups were matched according to PSM, respectively. Subsequently, patient characteristics other than age were not significantly different between the two groups. In the matched cohort, the older group had more patients with major complications (younger, 3.0%; older, 8.8%; P = 0.045).

CONCLUSION

Surgical outcomes of RAPN in older patients with RCC were comparable with those in younger patients, although older patients experiencedsignificantly more complications than younger patients. These results suggest the need for further detailed preoperative evaluation and appropriate postoperative management in older patients receiving RAPN.

Long-term prognosis after endoscopic submucosal dissection for esophageal cancer in older adult patients

BACKGROUND

The validity of endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma (ESCC) in older individuals with comorbidities remains unclear. Therefore, this study evaluated the safety and efficacy of ESD and additional treatment for ESCC in older adult patients.

METHODS

The clinicopathological characteristics and clinical outcomes of 398 consecutive older adult patients (≥ 65 years) with 505 lesions who underwent ESD for ESCC at the Hiroshima University Hospital between September 2007 and December 2019 were retrospectively evaluated. Additionally, the prognoses of 381 patients who were followed up for > 3 years were assessed.

RESULTS

The mean patient age and procedure time were 73.1 ± 5.8 years and 77.1 ± 43.5 min, respectively. The histological en bloc resection rate was 98% (496/505). Postoperative stenosis, perforation, pneumonia, and delayed bleeding were conservatively treated in 82 (16%), 19 (4%), 15 (3%), and 5 (1%) patients, respectively. The 5-year overall and disease-specific survival rates were 78.9% and 98.0%, respectively (mean follow-up time: 71.1 ± 37.3 months). Multivariate analysis showed that age and the American Society of Anesthesiologists classification of physical status class ≥III (hazard ratio: 1.27; 95% confidence interval: 1.01-1.59, p = 0.0392) were independently associated with overall survival. A significantly lower overall survival rate was observed in the high-risk follow-up group than in the low-risk follow-up and high-risk additional treatment groups (p < 0.01). However, no significant difference in disease-specific survival was observed among the three groups.

CONCLUSIONS

ESD is safe for ESCC treatment in patients aged ≥ 65 years. However, additional treatments should be considered based on the patient's general condition.

Endoscopic submucosal dissection versus surgery for T1b esophageal carcinoma: a single-center retrospective study

Introduction

Endoscopic submucosal dissection (ESD) is a preferred treatment option for superficial esophageal squamous cell carcinoma (SESCC). However, only few studies compared long-term survival outcomes of ESD with surgery, especially for T1b SESCC. This study compared the overall survival (OS), disease-free survival (DSS), recurrence-free survival (RFS), and complication rates of both, to evaluate the value of ESD in patients with T1b SESCC.

Methods

We reviewed patients who underwent ESD (n = 47) or surgery (n = 73) for T1b SESCC at Affiliated Hospital of Nanjing University of Chinese Medicine from 2009 to 2021. To increase the precision of our results interpretation, subgroups were analyzed according to the depth of tumor invasion and elderly people.

Results

In the ESD and surgery groups, the overall mortality rates were 0/100 and 12.3/100 person years, incidence rates of recurrence were 2.13/100 and 11/100 person years, respectively. Kaplan–Meier survival analysis revealed no significant different in OS, DSS and RFS. Charlson comorbidity index (CCI) and depth of submucosal invasion were identified as risk factors for cancer recurrence in multivariate analysis. For elderly people, no significant differences were found in OS, DSS and RFS between different treatments.

Conclusion

ESD are related to lower complication rates and shorter hospital stay than surgery in long-term outcomes for patients with pT1b SESCC. But in pT1b-SM2 patients, we still need long-term follow-up.

Effect of digital game intervention on cognitive functions in older adults: a multiple baseline single case experimental design study

BACKGROUND

Residents in nursing homes are prone to cognitive decline affecting memory, visuospatial cognition, and executive functions. Cognitive decline can lead to dementia, necessitating prioritized intervention.

METHODS

The current study aimed to investigate whether an intervention using a digital game was effective for preserving and improving the cognitive function of residents in nursing homes. An intervention study was conducted using a single-case AB design with multiple baselines. The participants in the study were five older adults aged 65 and over who do not play digital games regularly. The study ran for 15 weeks, including a baseline (phase A) and an intervention phase (phase B). Phase A had five baselines (5 to 9 weeks) with random participant assignment. In phase B, participants engaged in a digital game (Space Invaders) individually. Cognitive function was assessed as the outcome, measured using the Brain Assessment (performed on a tablet through the Internet) at 16 measurement points. Four of five participants (two female and two male) were included in the analysis, using visual inspection and Bayesian statistics with multi-level modeling.

RESULTS

Visual inspection of the graphs revealed cognitive function score improvements after the intervention for most layers in terms of memory of numbers, memory of words, mental rotation test (visuospatial ability), and total scores in the Brain Assessment. These effects were also significant in the analysis by multi-level modeling.

CONCLUSIONS

The results suggest that the use of digital games may be effective for preserving and improving cognitive function among residents of nursing home.

TRIAL REGISTRATION

This study was registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN000048677; public title: Effect of a Digital Game Intervention for Cognitive Functions in Older People; registration date: August 30, 2022).

Efficacy and safety of naldemedine for opioid-induced constipation in older patients with cancer: a retrospective study

BACKGROUND

Opioids are pain relievers that are often associated with opioid-induced constipation (OIC) that worsens with age. We performed a multicenter, retrospective analysis on the efficacy and safety of naldemedine, an opioid receptor antagonist, in treating OIC in patients with cancer (age >75 years).

METHODS

The electronic medical records of cancer patients who received naldemedine at 10 Japanese institutions between 7 June 2017 and August 31, 2019, were retrieved. Patients aged ≥75 years who were treated with naldemedine for the first time and hospitalized for at least 7 days before and after initiating naldemedine therapy were included in this analysis.

RESULTS

Sixty patients were observed for at least 7 days before and after starting naldemedine. The response rate was 68.3%, and the frequency of bowel movements increased significantly after naldemedine administration in the overall population ( P  < 0.0001) and among those who defecated <3 times/week before naldemedine administration ( P  < 0.0001). Diarrhea was the most frequent adverse event in all grades, observed in 45% of patients, of which 92.6% were Grade 1 or 2. Grade 4 or higher adverse events, including death, were not observed.

CONCLUSION

Naldemedine exhibits significant efficacy and safety in OIC treatment in older patients with cancer.

Diagnostic and Prognostic Value of Circulating DNA Fragments in Glioblastoma Multiforme Patients

Novel blood-circulating molecules, as potential biomarkers for glioblastoma multiforme (GBM) diagnosis and monitoring, are attracting particular attention due to limitations of imaging modalities and invasive tissue biopsy procedures. This study aims to assess the diagnostic and prognostic values of circulating cell-free DNA (cfDNA) in relation to inflammatory status in GBM patients and to determine the concentration and average size of DNA fragments typical of tumour-derived DNA fractions. Preoperative plasma samples from 40 patients (GBM 65.0 ± 11.3 years) and 40 healthy controls (HC 70.4 ± 5.4 years) were compared. The cfDNA concentrations and lengths were measured using the electrophoresis platform, and inflammatory indices (NLR, PLR, LMR, and SII) were calculated from complete blood cell analysis. More fragmented cfDNA and 4-fold higher 50-700 bp cfDNA concentrations were detected in GBM patients than in healthy controls. The average cfDNA size in the GBM group was significantly longer (median 336 bp) than in the HC group (median 271 bp). Optimal threshold values were 1265 pg/μL for 50-700 bp cfDNA (AUC = 0.857) and 290 bp for average cfDNA size (AUC = 0.814). A Kaplan-Meier survival curves analysis also demonstrated a higher mortality risk in the GBM group with a cut-off >303 bp cfDNA. This study is the first to have revealed glioblastoma association with high levels of cfDNA > 1000 pg/μL of 50-700 bp in length, which can be aggravated by immunoinflammatory reactivity.

Lung Cancer Surgery in Octogenarians: Implications and Advantages of Artificial Intelligence in the Preoperative Assessment

The general world population is aging and patients are often diagnosed with early-stage lung cancer at an advanced age. Several studies have shown that age is not itself a contraindication for lung cancer surgery, and therefore, more and more octogenarians with early-stage lung cancer are undergoing surgery with curative intent. However, octogenarians present some peculiarities that make surgical treatment more challenging, so an accurate preoperative selection is mandatory. In recent years, new artificial intelligence techniques have spread worldwide in the diagnosis, treatment, and therapy of lung cancer, with increasing clinical applications. However, there is still no evidence coming out from trials specifically designed to assess the potential of artificial intelligence in the preoperative evaluation of octogenarian patients. The aim of this narrative review is to investigate, through the analysis of the available international literature, the advantages and implications that these tools may have in the preoperative assessment of this particular category of frail patients. In fact, these tools could represent an important support in the decision-making process, especially in octogenarian patients in whom the diagnostic and therapeutic options are often questionable. However, these technologies are still developing, and a strict human-led process is mandatory.

A Multicenter Evaluation of Different Chemotherapy Regimens in Older Adults With Head and Neck Squamous Cell Carcinoma Undergoing Definitive Chemoradiation

PURPOSE

The number of older adults with head and neck squamous cell carcinoma (HNSCC) is increasing, and treatment of these patients is challenging. Although cisplatin-based chemotherapy concomitantly with radiation therapy is considered the standard regimen for patients with locoregionally advanced HNSCC, there is substantial real-world heterogeneity regarding concomitant chemotherapy in older patients with HNSCC.

METHODS AND MATERIALS

The SENIOR study is an international multicenter cohort study including older patients (≥65 years) with HNSCC treated with definitive radiation therapy at 13 academic centers in the United States and Europe. Patients with concomitant chemoradiation were analyzed regarding overall survival (OS) and progression-free survival (PFS) via Kaplan-Meier analyses. Fine-Gray competing risk regressions were performed regarding the incidence of locoregional failures and distant metastases.

RESULTS

Six hundred ninety-seven patients with a median age of 71 years were included in this analysis. Single-agent cisplatin was the most common chemotherapy regimen (n = 310; 44%), followed by cisplatin plus 5-fluorouracil (n = 137; 20%), carboplatin (n = 73; 10%), and mitomycin C plus 5-fluorouracil (n = 64; 9%). Carboplatin-based regimens were associated with diminished PFS (hazard ratio [HR], 1.39 [1.03-1.89]; P < .05) and a higher incidence of locoregional failures (subdistribution HR, 1.54 [1.00-2.38]; P = .05) compared with single-agent cisplatin, whereas OS (HR, 1.15 [0.80-1.65]; P = .46) was comparable. There were no oncological differences between single-agent and multiagent cisplatin regimens (all P > .05). The median cumulative dose of cisplatin was 180 mg/m2 (IQR, 120-200 mg/m2). Cumulative cisplatin doses ≥200 mg/m2 were associated with increased OS (HR, 0.71 [0.53-0.95]; P = .02), increased PFS (HR, 0.66 [0.51-0.87]; P = .003), and lower incidence of locoregional failures (subdistribution HR, 0.50 [0.31-0.80]; P = .004). Higher cumulative cisplatin doses remained an independent prognostic variable in the multivariate regression analysis for OS (HR, 0.996 [0.993-0.999]; P = .009).

CONCLUSIONS

Single-agent cisplatin can be considered in the standard chemotherapy regimen for older patients with HNSCC who can tolerate cisplatin. Cumulative cisplatin doses are prognostically relevant in older patients with HNSCC.

Age-wise examination of the association of obesity based on body mass index and waist circumference with metabolic diseases in comprehensive health checkup participants

Aim

Body mass index and waist circumference are used for obesity diagnosis and screening of visceral fat; however, their evidence in older adults is insufficient. This study investigated the age-specific association of body mass index and waist circumference with metabolic diseases, assessing their applicability as diagnostic criteria for individuals aged ≥65 years.

Methods

Analysis included 46,324 individuals aged ≥18 years, categorized into five age groups: 18-44, 45-54, 55-64, 65-74, and ≥75 years. Logistic regression analyses identified associations between obesity and metabolic diseases, stratified by age and sex.

Results

Men with obesity based on body mass index had a significantly high risk of hypertension, diabetes mellitus, and dyslipidemia across all age groups (all, p < 0.05). Obesity based on waist circumference was significantly positively associated with all metabolic diseases (all, p < 0.05). Women with obesity based on body mass index and waist circumference had a significantly high risk of all metabolic diseases across all age groups (all, p < 0.05), except for diabetes mellitus in individuals aged ≥75 years.

Conclusions

Participants with obesity based on body mass index and waist circumference exhibited a high risk of hypertension, diabetes mellitus, and dyslipidemia among those aged 18-74 years and men aged ≥75 years. This study contributes to the early prevention and control of metabolic diseases.

Technetium-99m-pyrophosphate imaging-based computed tomography-guided core-needle biopsy of internal oblique muscle in wild-type transthyretin cardiac amyloidosis

BACKGROUND

Technetium-99m-pyrophosphate (99mTc-PYP) uptake in the internal oblique muscle (IOM), which is often observed in patients with wild-type transthyretin cardiac amyloidosis (ATTR-CA), indicates amyloid transthyretin (ATTR) deposition.

OBJECTIVE

This study aimed to assess the safety and efficacy of 99mTc-PYP imaging-based computed tomography (CT)-guided core-needle biopsy of the IOM as a new extracardiac screening biopsy for confirming the presence of ATTR deposits.

METHODS

Patients with suspected ATTR-CA in whom myocardial tracer uptake was detected on chest- and abdomen-centered images of 99mTc-PYP scintigraphy underwent CT-guided core-needle biopsy at the site with the highest tracer uptake in the IOM between September 2021 and November 2022.

RESULTS

All 18 consecutive patients (mean age, 86.3 years ± 6.5; 61.1% male) enrolled in the study showed 99mTc-PYP uptake into the IOM. Adequate tissue samples were obtained from all patients except one without serious complications. Immunohistochemical analysis confirmed ATTR deposits in 16/18 (88.9%) patients. In the remaining two patients, ATTR deposits were observed via endomyocardial biopsy. All patients were diagnosed with wild-type ATTR-CA based on transthyretin gene sequence testing results.

CONCLUSION

In wild-type ATTR-CA, 99mTc-PYP imaging-based CT-guided core-needle biopsy of the IOM could be used as an extracardiac screening biopsy to confirm the presence of ATTR deposits.

Checklist for Habitual Physical Activity (CHaPA) for adults 75 years and older: tool development and content and face validation

BACKGROUND

Physical activity significantly contributes to older adults' physical and mental health, suggesting that physical activity could enhance healthy life expectancy. Despite its importance for adults aged 75 and older, activity levels among a large proportion of individuals aged 75 and older in Japan do not meet the recommended levels of physical activity, indicating a need for specific strategies tailored to this age group. This study aimed to develop a screening tool that measures daily activities promoting physical activity among older adults and assessed its content and face validity.

METHODS

In Stage 1, we derived constructs pertinent to physical activity from previous literature and formulated an item list based on a prior qualitative study we undertook in Japan that evaluated daily behaviours facilitating physical activity among older adults. During Stage 2, we assessed the content and face validity of the list utilising the Nominal Group Technique (NGT), involving eight experts. The content validity was confirmed through two scoring evaluation rounds, while the face validity was verified through the NGT discussion, focusing on the comprehensibility and appropriateness of the tool.

RESULTS

We created a tool with 22 items consisting of three constructs. The NGT participants modified eight of these items for the final assessment, resulting in a finalised tool comprising 22 items that satisfied the adaptation criteria. The content validity of these items was affirmed by median adequacy (>5.0 points) and interquartile range (<1.0 points). The NGT discussion consensus also confirmed satisfactory face validity.

CONCLUSION

The newly developed tool, Checklist for Habitual Physical Activity (CHaPA) for adults 75 years and older, is a valid screening tool to assess the daily behaviours that facilitate physical activity. This self-administered instrument aims to assist older adults who need to start and maintain physical activity daily. Before its widespread public deployment, further investigation of the tool's validity and reliability is necessary.

Radiotherapy with or without chemotherapy for locally advanced head and neck cancer in elderly patients: analysis of the Head and Neck Cancer Registry of Japan

BACKGROUND

Whether concurrent chemotherapy with radiotherapy (CRT) is effective for elderly patients with head and neck cancer is a controversial topic. This study aimed to analyze the effectiveness of CRT vs. radiation therapy (RT) among elderly patients in Japan.

METHODS

Data from the Head and Neck Cancer Registry of Japan were extracted and analyzed. Patients with locally advanced squamous cell carcinoma of the oropharynx, hypopharynx, or larynx who received definitive CRT or RT between 2011 and 2014 were included.

RESULTS

CRT was administered to 78% of the 1057 patients aged ≥ 70 years and 67% of the 555 patients aged ≥ 75 years. For the patients aged ≥ 75 years, the overall survival (OS) rate was significantly better in the CRT group than in the RT group (P < 0.05), while the progression-free survival (PFS) rate was not significantly different (P > 0.05). The add-on effect of CRT was significantly poor in elderly patients (P < 0.05), and it was not a significant factor in the multivariate analysis for patients aged ≥ 75 years. After propensity score matching, there were no significant differences in the OS and PFS rates between the patients aged ≥ 70 years and those aged ≥ 75 years (all, P > 0.05).

CONCLUSION

Although aggressive CRT is administered to elderly patients in Japan, its effectiveness is uncertain. Further prospective randomized trials are needed to verify whether CRT is superior to RT alone for elderly patients.

Does Old Age Comprise Distinct Subphases? Evidence from an Analysis of the Relationship between Age and Activities of Daily Living, Comorbidities, and Geriatric Syndromes

BACKGROUND

Older individuals are usually treated as a homogenous group despite evidence that old age consists of distinct subphases. This observational study including 493 older patients aimed to identify differences among age subgroups of older persons. Receiver operating characteristic (ROC) curve analysis was then applied to identify the optimal age cutoff points to distinguish those age groups.

METHODS

Data were collected on the demographics of older patients, their medical and medication histories, dependence on activities of daily living (ADLs), and instrumental activities of daily living (IADLs). Non-parametric tests (Kruskal-Wallis and Mann-Whitney U tests) and ROC curves were used for statistical analysis.

RESULTS

The 65-79 and ≥80 years of age groups showed distinct frailty status, comorbidity, and dependency in ADLs. The median age to remain completely independent in IADLs was 76-79 years, while the median age for being free from geriatric syndromes was slightly higher (77-80 years) and reached 82 years for the absence of delirium, falls, and swallowing problems. In the ROC analysis, the optimal cutoff ages for the presence of frailty, cognitive impairment, and dependency in ADLs were 80-82 years.

CONCLUSION

The 65-79 and ≥80 years of age groups differed significantly in numerous parameters, underscoring the need to address these distinct age groups differently, both for applying medical therapies and interventions, as well as for conducting health research.

Consensus statement on the management of late-onset rheumatoid arthritis

OBJECTIVES

Late-onset rheumatoid arthritis (LORA), which has been increasing in recent years, lacks evidence for initial treatment. Japanese rheumatology experts recognized this gap and addressed it by developing consensus statements on the first clinical application of LORA.

METHODS

These statements were created following an introductory discussion about treatment fundamentals, which included a review of existing literature and cohort data. The steering committee created a draft, which was refined using a modified Delphi method that involved panel members reaching a consensus. The panel made decisions based on input from geriatric experts, clinical epidemiologists, guideline developers, patient groups, and the LORA Research Subcommittee of the Japan College of Rheumatology.

RESULTS

The consensus identified four established facts, three basic approaches, and six expert opinions for managing LORA. Methotrexate was recommended as the primary treatment, with molecular-targeted agents being considered if treatment goals cannot be achieved. An emphasis was placed on assessing the lives of older patients due to challenges in risk management and methotrexate accessibility caused by comorbidities or cognitive decline.

CONCLUSIONS

The experts substantiated and refined 13 statements for the initial treatment of LORA. To validate these claims, the next is to conduct a registry study focusing on new LORA cases.

Risk of hospitalized infections in older elderly patients with rheumatoid arthritis treated with tocilizumab or other biological/targeted synthetic disease-modifying antirheumatic drugs: Evaluation of data from a Japanese claims database

OBJECTIVE

We compared the incidence rates of hospitalized infections (HIs) between tocilizumab (TCZ) and other biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in adults aged ≥75 years with rheumatoid arthritis (RA).

METHODS

We used a Japanese claims database from Medical Data Vision Co., Ltd (Tokyo, Japan) to perform a retrospective longitudinal population-based study in patients with RA who were prescribed b/tsDMARDs between 2014 and 2019. We calculated adjusted risk ratios (aRRs) for HIs in three age groups (<65, ≥65 and <75, and ≥75 years).

RESULTS

Of 5506 patients, 2265 (41.1%) were <65 years, 1709 (31.0%) were 65-74 years, and 1532 (27.8%) were ≥75 years. Crude incidence rates (/100 person-years) of HIs were 3.99, 7.27, and 10.77, respectively. In the oldest group, aRRs (95% confidence interval) for HIs (b/tsDMARDs versus TCZ) were as follows: etanercept, 2.40 (1.24-4.61); adalimumab, 1.90 (0.75-4.83); golimumab, 1.21 (0.66-2.23); and abatacept, 0.89 (0.49-1.62). In the other age groups, the noticeable difference was a lower aRR of etanercept versus TCZ in the youngest group (0.30, 0.11-0.85).

CONCLUSION

In patients with RA aged ≥75 years, b/tsDMARDs have a similar risk of HIs to tocilizumab except for etanercept.

Effectiveness and safety of treat-to-target strategy for methotrexate-naïve rheumatoid arthritis patients >75 years of age

Objectives

To identify differences in effectiveness and safety of a treat-to-target (T2T) strategy comparing late-onset MTX-naïve RA patients (LORA) ≥75 or <75 years of age.

Methods

Treatment was adjusted to target low disease activity with conventional synthetic DMARDs followed by biologic DMARDs (bDMARDs) in LORA ≥75 years (n = 98, mean age 80.0 years) and LORA <75 years (n = 99) with moderate-high disease activity. Achievement of Simplified Disease Activity Index (SDAI) remission at week 156 by non-responder imputation analysis was evaluated as a primary outcome.

Results

LORA ≥75 years had more comorbidities than LORA <75 years, but SDAI and ACPA positivity were similar at baseline. Of the LORA ≥75 years, 70.4% started MTX and 34.1% and 37.1% received a bDMARD at week 52 and 156, respectively (very similar to the LORA <75 years). Glucocorticoid use was more frequent in the LORA ≥75 years than in the LORA <75 years. Comorbidities/adverse events more frequently contributed to the reasons for non-adherence to T2T in the LORA ≥75 than in the LORA <75. At week 156, 32.7% of the LORA ≥75 and 66.7% of the LORA <75 achieved SDAI remission (P < 0.001). The cumulative incidence of serious adverse events (SAEs) over 156 weeks was 42.8% in the LORA ≥75 and 22.1% in the LORA <75. Multivariable analysis indicated an increased risk of SDAI non-remission at week 156 in the LORA ≥75 [odds ratio 2.82 (95% CI 1.29. 6.14)] after adjusting for comorbidities at baseline, non-adherence to T2T and SAEs.

Conclusions

It was more difficult to achieve remission in the LORA ≥75 patients than in the LORA <75 patients due to both poor treatment response and safety issues.

Pulmonary Vein Isolation in Elderly Patients ≥ 75 Years: A Propensity Score-Matched Analysis With Focus on Differences Among Atrial Fibrillation Types

BACKGROUND

Age is a major risk factor for development of atrial fibrillation (AF) and associated with increased recurrence rates in the setting of rhythm control. Current data tend to support catheter ablation in elderly patients, but uncertainties exist regarding efficacy and safety of ablation in elderly patients.

METHODS

This was a prospective single-centre observational study with propensity score matching (PSM) to investigate the influence of age on efficacy and safety of cryoballoon ablation (CBA) stratified by age (< 75 years vs ≥ 75 years) and AF phenotype (paroxysmal vs persistent). Primary efficacy endpoint was recurrence of atrial arrhythmia after a 90-day blanking period. Safety endpoints were death, stroke, or procedure-associated complications.

RESULTS

Consecutive patients (n = 953) underwent CBA for first-time AF ablation. Median follow-up was 18 months. By means of PSM, 268 matches were formed. At 1 year, primary efficacy endpoint occurred in 22.4% of young vs 33.2% of elderly patients, including both AF phenotypes (hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.47-0.90; P = 0.01). AF relapse occurred in 19.7% of young vs 28.5% of elderly patients with paroxysmal (HR, 0.63; 95% CI, 0.40-0.99; P = 0.046) compared with 25.9% (30 of 116, young) vs 38.8% (45 of 116, elderly) patients with persistent AF (HR, 0.62; 95% CI, 0.39-0.97; P = 0.038). No difference was observed regarding the incidence of safety endpoints between young and elderly patients (P = 0.38).

CONCLUSIONS

CBA is associated with higher recurrence rates in elderly (≥ 75 years) than in younger patients, with highest recurrence rates in elderly patients with persistent AF.

The effect of aging on short- and long-term results after esophagectomy: an international multicenter retrospective analysis

The optimal treatment for esophageal cancer in elderly patients is still debated and data on postoperative results are limited. This retrospective international study aims to clarify the impact of age on clinical and oncological outcomes after esophagectomy. All patients that underwent esophagectomy for cancer between 2007 and 2016 at two European high-volume Centers have been included in the study. Patients were divided into three groups according to their age: young-age group (YAG) (18-69), middle-age group (70-74) and old-age group (>74). Primary outcome was 5-year overall survival (OS), while secondary outcomes considered were 5-year disease free survival and disease related survival, 90-day morbidity and mortality, readmission rate and radicality. A total of 575 patients were included. No differences emerged in terms of morbidity and length of stay, while mortality increased with aging from 2% in YAG to 4.8% in old-aged (P = 0.003). Old-age patients had less neoadjuvant treatment (P < 0.001), a less aggressive mediastinal lymphadenectomy and presented a more advanced pathological stage. As expected, OS decreased significantly for older patients compared with the other two age groups (P = 0.044) but, on the other hand, disease free and disease related survival were comparable between the groups. Age itself should not be considered a contraindication to esophagectomy. Although in patients older than 75 years postoperative mortality is significantly increased, esophagectomy could be still an option in selected patients, favoring the use of minimally invasive techniques and enhanced recovery protocols.

Anemia in patients ≥ 75 years with metastatic clear cell renal cell carcinoma: an important poor prognostic factor in the international metastatic renal cell carcinoma database consortium model

BACKGROUND

Due to an increase in life expectancy, the incidence of metastatic renal cell carcinoma (mRCC) in patients aged ≥75 years has been increasing. In this study we investigated the characteristics before treatment and the outcomes of systemic therapies for patients aged ≥75 years with mRCC and compared the results with those for patients aged < 75 years in order to determine whether differences in age influenced survival.

METHODS

A total of 206 consecutive Japanese patients with mRCC, including 47 patients aged ≥75 years, who received systemic therapy were included. Clinical data from medical records were retrieved and analyzed retrospectively. Survival analyses were determined using a Kaplan-Meier method, and analyzed with a log-rank test.

RESULTS

Elderly patients categorized as favorable risk group based on the International Metastatic RCC Database Consortium (IMDC) stratification system were significantly lower. Among IMDC risk factors, the rate of anemia was significantly higher in elderly patients. No statistically significant benefit in progression free survival for first and second line treatment was observed, whereas improvements in overall survival as well as cancer specific survival were seen in patients aged < 75 years.

CONCLUSIONS

For mRCC patients aged ≥75 years, a higher proportion of base line anemia, which resulted in higher rates of IMDC intermediate/poor risk, would be responsible for shorter OS/CSS. Furthermore, mRCC patients aged ≥75 years tend to receive BSC instead of second line active treatment. Overcoming under-treatment in elderly patients might help to prolong survival in mRCC.

Effect of emergency general surgery on postoperative performance status in patients aged over 90 years

Background

Functional deterioration following emergency general surgery (EGS) poses a significant challenge in super-elderly patients. However, limited research has focused on assessing the deterioration in postoperative performance status (PS). This study aimed to investigate the impact of EGS on PS deterioration in super-elderly patients, and the extent to which deteriorated PS is recovered.

Methods

This historical cohort study comprised 77 super-elderly patients who underwent EGS between July 2015 and December 2020. Functional deterioration was evaluated by comparing preoperative and postoperative Eastern Cooperative Oncology Group Performance Status (ECOG-PS). The Emergency Surgical Score (ESS) was used as a risk-adjustment tool. Questionnaires were mailed to the patients and their families to assess post-discharge PS and obtain their impressions of EGS.

Results

Postoperative PS deteriorated in 35/77 patients (45.5 %). Significant differences were observed between the groups in terms of sex, serum C-reactive protein (CRP) levels, ESS scores, preoperative ECOG-PS, duration of operation, and major complications. Multivariate analysis of preoperative factors showed that ESS ≥7 (OR: 3.7, 95 % CI: 1.0-13), preoperative ECOG-PS ≤2 (OR: 5.9, 95 % CI: 1.7-21), and female sex (OR: 5.8, 95 % CI: 1.6-21) were associated with postoperative ECOG-PS deterioration. According to the questionnaire results, PS recovery post-discharge was observed in 6/36 (17 %) patients, and 34/36 (94 %) patients and their families expressed positive impressions of EGS.

Conclusions

EGS in super-elderly patients highly caused a deterioration in their PS, particularly in patients with maintained preoperative PS. PS hardly recovered; however, most patients and their families had positive impressions of the EGS.

Key message

We assessed the pre- and postoperative performance status of super-elderly patients who underwent emergency general surgery. Surgery caused a marked deterioration in patients' functional performance, which seldom recovered postoperatively.

Treatment of olecranon fractures in older individuals: a cross-sectional survey of surgeon treatment preferences

Background

With an aging population, the incidence of olecranon fractures in older patients is increasing. The standard of care has traditionally included operative management for displaced fractures. Recent literature has called this standard of care into question. Older patients may be at increased risk of operative complications and may have satisfactory functional outcomes with nonoperative management. Given recently evolving evidence, the current treatment preferences of orthopedic surgeons for older patients with displaced olecranon fractures are unknown.

Methods

We administered a cross-sectional survey of Canadian orthopedic surgeons via e-mail invitation and online survey form to determine treatment preferences for patients aged 65-75 and >75 years with simple displaced and comminuted displaced stable olecranon fractures. Respondents reviewed representative images and were asked to indicate their preferred treatment based on patient age. We also asked respondents to indicate their perceived importance of 11 patient factors on treatment decision-making.

Results

We received 200 responses (33.8% response rate). For patients aged 65-75 years with simple displaced fractures, surgeons preferred tension-band wiring (n = 110, 56%) to plating (n = 82, 42%, P = .005), while only 3% (n = 5) preferred nonoperative treatment. For patients aged >75 years with simple displaced fractures, surgeons preferred operative (n = 144, 73%) to nonoperative management (n = 51, 26%; P < .01) with either tension-band wiring (n = 77, 39%) or plating (n = 67, 34%). In these patients, early range of motion (n = 35, 18%) was preferred to immobilization (n = 16, 8%; P = .004). For comminuted fractures, plate fixation was preferred for patients aged 65-75 years (n = 189, 95%) and >75 years (n = 131, 68%). In patients aged >75 years, this was followed by early range of motion (n = 35, 18%) and immobilization (n = 24, 13%). Of the 11 factors surveyed, participation in high-intensity activities (mean rank = 9.4), independent living (mean rank = 8.8), and disrupted extensor mechanism (mean rank = 8.3) were ranked most highly for increasing likelihood of surgical treatment.

Conclusion

In patients aged 65 to 75 years, operative management is favored by most surgeons, with tension-band wiring preferred over plating for simple displaced fractures. In patients aged >75 years, operative management is again preferred by most respondents for simple and comminuted fractures. Despite operative preferences, there is a paucity of quality evidence to guide treatment decision-making, particularly in patients aged >75 years.

Continuous laxative use and its relationship to defecation among residents of nursing homes: A longitudinal observational study using the interRAI

AIM

To clarify the association between constipation, diarrhea, and long-term laxative use in Japanese nursing home residents.

METHODS

Data from 306 residents with chronic constipation aged over 75 years for basic characteristics, medication use, activities of daily living, and concurrent illness were collected via two consecutive 6-monthly surveys conducted using the Japanese interRAI assessment tool. We used bivariate and multivariate analyses to examine the associations between chronic constipation, diarrhea, and continuous laxative use.

RESULTS

Chronic constipation persisted in 74.5% of residents despite their continuous use of laxatives. Additionally, 14.4% experienced chronic diarrhea while on laxatives. Residents using salt laxatives had significantly lower chronic constipation than those not using salt laxatives (adjusted odds ratio [AOR] 0.52), while residents using novel laxatives had significantly higher chronic diarrhea than those not using novel laxatives (AOR 4.28).

CONCLUSIONS

Our findings reveal that bowel movement-related problems remain a concern and highlight the need for further research on the use of novel laxatives in nursing home residents. Geriatr Gerontol Int 2024; 24: 133-139.

Utility of palliative prognostic index and neutrophil-to-lymphocyte ratio in predicting prognosis of end-stage squamous cell carcinoma of head and neck

BACKGROUND

The purpose of this study was to examine the factors influencing the prognosis of end-stage head and neck squamous cell carcinoma (HNSCC) and to develop a more useful prognostic index.

PATIENTS AND METHODS

This retrospective observational study included 79 patients with end-stage HNSCC. Patients were grouped by patient factors and prognostic indicators, and overall survival from the start of Best Supportive Care was compared for each group. In addition, overall survival was compared between patients with palliative prognostic index (PPI) ≥6 and neutrophil-to-lymphocyte ratio (NLR) ≥10 and patients with PPI <6 or NLR <10.

RESULTS

PPI ≥6 and NLR ≥10 were associated with significantly more frequent poor prognoses (p = 0.01 and p = 0.002, respectively). The median survival was 32 days in cases with PPI ≥6 and NLR ≥10, and 64 days for PPI <6 or NLR <10 (p < 0.001).

CONCLUSION

The combination of PPI and NLR is a useful indicator for predicting the prognosis of patients with end-stage HNSCC.

Perceived quality of life and associated factors in long COVID syndrome among older Brazilians: A cross-sectional study

AIMS AND OBJECTIVES

This paper aims to: (a) determine the personal, sociodemographic, clinical, behavioural, and social characteristics of older Brazilians with clinical evidence of long COVID; (b) evaluate perceived quality of life and determine its association with personal, sociodemographic, behavioural, clinical and social variables; and (c) assess significant predictors of high perceived QoL.

BACKGROUND

Given the inherent vulnerabilities of the ageing process, the older people are an at-risk group for both contagion of SARS-CoV-2 and the perpetuation of residual symptoms after infection, the so-called long COVID or post-COVID syndrome.

DESIGN

A cross-sectional survey design using the STROBE checklist.

METHODS

Brazilian older people with long COVID syndrome (n = 403) completed a phone survey measuring personal, sociodemographic, behavioural, clinical, and social characteristics, and perceived Quality of Life (QoL). Data were collected from June 2021-March 2022. A multiple linear regression model was performed to identify salient variables associated with high perceived QoL.

RESULTS

The mean age of participants was 67.7 ± 6.6 years old. The results of the multivariate regression model showed that race, home ownership, daily screen time, musculoskeletal and anxiety symptoms, and work situation were the significant predictors of QoL among COVID-19 survivors.

CONCLUSIONS

Knowledge about the persistence of physical, emotional, and social symptoms of COVID-19 can help nurses and other healthcare providers to improve the management of survivors, bringing benefits to the whole society.

RELEVANCE TO CLINICAL PRACTICE

Given the novelty of long-COVID and its heterogeneous trajectory, interventions focusing on the repercussions and requirements unique to more vulnerable older persons should be developed and these aspects should be included in public health recommendations and policymakers' concerns.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution was required to design, to outcome measures or undertake this research. Patients/members of the public contributed only to the data collection.

Prognostic factors in mobility disability among elderly patients in the emergency department: A single-center retrospective study

Aim

We aimed to evaluate the clinical characteristics and outcomes of elderly critically ill patients and identify prognostic factors for mobility disability at discharge.

Methods

This single-center, retrospective cohort study investigated the period from April 2020 to January 2021. Patients ≥75 years old transferred to our emergency department and admitted to the intensive care unit (ICU) or intermediate unit in our hospital were eligible. Demographics, clinical characteristics, nutritional indicators, and nutritional screening scores were collected from chart reviews and analyzed. The primary outcome was the prevalence of mobility disability, compared to that of no mobility disability.

Results

A total of 124 patients were included in this present study. Median age was 83.0 years (interquartile range [IQR], 79.8-87.0 years) and 48 patients (38.7%) were female. Fifty-two patients (41.9%) could not walk independently at discharge (mobility disability group). The remaining 72 patients were in the no mobility disability group. Multiple logistic regression analyses revealed clinical frailty scale (CFS) score ≥5 (odds ratio [OR] = 6.63, 95% confidence interval [CI] = 2.51-17.52, p < 0.001), SOFA score ≥6 (OR = 6.11, 95% CI = 1.57-23.77, p = 0.009), and neurological disorder as the main cause on admission (OR = 4.48, 95% CI = 1.52-13.20, p = 0.006) were independent and significant prognostic factors for mobility disability at discharge.

Conclusion

Among elderly patients admitted to the emergency department, CFS ≥5, SOFA ≥6, and neurological disorders were associated with mobility disability at hospital discharge.

Factors associated with impaired physical function in elderly rheumatoid arthritis patients who had achieved low disease activity

OBJECTIVES

We aimed to investigate factors associated with impaired physical function [defined as Health Assessment Questionnaire Disability Index (HAQ-DI) >0.5] of old-old (aged 75-84 years) patients with rheumatoid arthritis.

METHODS

Data from 15,185 rheumatoid arthritis patients in the National Database of Rheumatic Disease in Japan were extracted from 2017 to 2018. We enrolled 3708 patients aged 55-84 years in Simplified Disease Activity Index (SDAI) ≤11 and Steinbrocker Stage I/II. Factors associated with HAQ-DI >0.5 were analysed by multivariable logistic regression.

RESULTS

About half of the old-old patients received methotrexate, which was lower than middle-aged (55-64 years) and young-old patients (65-74 years). The proportion of glucocorticoids in the old-old patients was highest among the three groups, and biological disease-modifying antirheumatic drugs were similarly used. The prevalence of HAQ-DI >0.5 was significantly higher in old-old patients with low disease activity than in those with remission. The same was true in the middle-aged and young-old patients. Multivariable analysis showed age, higher SDAI, glucocorticoid use, and methotrexate nonuse were significantly associated with HAQ-DI >0.5 in the old-old patients.

CONCLUSIONS

Achieving SDAI remission was an ideal goal for old-old patients in terms of physical function. Glucocorticoids and a low proportion of methotrexate use may influence the physical function of old-old patients.

Age-group-specific association of oral health and systemic health on cognitive function: a cross-sectional study of Korean elders

BACKGROUND

Although the importance of oral and systemic healthcare for elderly people is increasing owing to the rapid ageing of the population in South Korea, studies on the relationship between oral health, systemic health, and cognitive function, as well as on the prediction of cognitive function by oral and systemic health depending upon age groups are lacking.

METHODS

We included 5,975 out of 6,488 participants from the 8th wave of the Korean Longitudinal Study of Aging (KLoSA) panel data, divided the participants into three age groups, and performed a hierarchical multiple linear regression analysis to explain cognitive function with four types of predictors: oral health status, sociodemographic factors, objective health status, and subjective health status.

RESULTS

Oral health status was positively correlated with systemic health status and cognitive function. Of all ages over 54, cognitive function was significantly predicted by oral health variables, such as the number of functional teeth, masticatory ability, and Geriatric Oral Health Assessment Index (GOHAI); sociodemographic variables, such as age, sex, education level, and residence; and systemic health variables, such as diagnosis of diabetes mellitus, cancer or malignant tumours, cerebrovascular disease and rheumatoid arthritis, depressive symptom, and self-rated health status. Oral health variables explained cognitive function differently by age group; GOHAI appeared important predictor in the group aged < 75 years, whereas the number of functional teeth did in the group aged ≥ 75 years. Educational level, masticatory ability, depressive symptoms, and self-rated health status were pivotal factors age-independently.

CONCLUSIONS

The general and age-group-specific association between oral health, systemic health, and cognitive function were confirmed, suggesting that age-group-specific oral healthcare should be emphasized for the effective management of systemic and cognitive health in the elderly group.

Efficacy and safety of the vein of Marshall ethanol infusion with radiofrequency catheter ablation for the treatment of persistent atrial fibrillation in elderly patients

Background

Increasing age is a significant risk factor for atrial fibrillation (AF) recurrence after catheter ablation (CA). We accomplished this study to evaluate the efficacy and safety of the vein of Marshall (VOM) ethanol infusion (VOM-EI) with CA in elderly patients with persistent AF (PsAF).

Methods

This retrospective observational study included 360 consecutive adult patients with PsAF, of which 141 were in the Elder group (age ≥65 years) and 219 were in the Younger group (age <65 years), who underwent the VOM-EI and radiofrequency CA (RFCA) between May 2020 and April 2022. The efficacy endpoint was no recurrence of AF within one year after CA.

Results

The VOM-EI was successfully performed in 90.8% of patients from the Elder and 88.6% from the Younger group. All patients achieved PVI; 97.9% of patients from the Elder and 98.6% from the Younger group reached LA roof block, and 93.6% of patients from the Elder and 95.9% from the Younger group achieved MI block. There was no significant difference in 1-year survival without recurrence of AF between the two groups (83.0% and 84.5%, respectively). The incidence of complications within 30 days after the procedure from the two groups was low and did not differ significantly.

Conclusion

The VOM-EI combined with RFCA proved to be an effective and safe strategy for treating PsAF in elderly and younger patients.

Hindfoot nailing without joint preparation for ankle fractures in extremely elderly patients: Comparison of clinical and patient-reported outcomes with standard ORIF

INTRODUCTION

Tibiotalocalcaneal (TTC) nailing without joint preparation has been indicated as an alternative to open reduction and internal fixation (ORIF) in the treatment of unstable fragility ankle fractures. We hypothesized that primary hindfoot nailing without joint preparation, and immediate weight bearing can provide a safe and effective treatment for unstable fragility fractures of the ankle compared to ORIF.

METHODS

A retrospectively single-center cohort was reviewed for all surgically treated ankle fractures in patients aged 75 years and older between 2016 and 2021. The cases were grouped by the surgical technique: ORIF or TTC nailing. Diagnosis and treatment were validated by a review of the radiographs and the patients' charts. Primary outcomes included complication rates and revision rates. The PROMs questionnaires included the Foot and Ankle-Ability Measure (FAAM-ADL) and the Olerud-Molander Ankle Score (OMAS).

RESULTS

Forty-six cases met the inclusion criteria during the study period. Eighteen in the TTC group and 28 in the ORIF group. The average follow-up was 46.4 months (Median 49.5, SD ± 25.3). The mean age of the TTC group was significantly higher (88.6 versus 81.8, p < 0.001). The mean surgery duration and length of stay were similar. The complication rates were 50.0 % in the ORIF group (28.6 % major) versus 22.2 % in the TTC group (5.6 % major), (p = 0.060). The revision rates were 28.6 % and 11.1 % in the ORIF and TTC groups respectively (p = 0.161). The FAAM-ADL was higher in the ORIF group (62.6 % versus 32.4 %, p = 0.020), as well as the OMAS (60.0 versus 32.8, p = 0.029).

CONCLUSION

TTC nailing without joint preparation for unstable fragility fractures of the ankle in the extremely elderly provided a better complication profile compared to traditional ORIF. However, PROMs were inferior.

Generation-Dependent Retention Rates and Reasons for Discontinuation of Molecular Targeted Therapies in Patients with Rheumatoid Arthritis: From FIRST Registry

INTRODUCTION

The study aimed to optimize medical care for elderly patients with rheumatoid arthritis (RA) by examining the 3-year continuation rate of different molecular targeted therapies across age groups in Japan, which has a significant elderly population.

METHODS

The study included patients with RA who started molecular targeted therapies between 2013 and 2019 and divided them into three age groups. The primary outcome was to assess the 3-year continuation rate of each drug and analyze reasons for treatment discontinuation using inverse probability of treatment weighting.

RESULTS

Among 2292 patients analyzed, tumor necrosis factor (TNF) inhibitors were most commonly used in those younger than 65 years of age (43.5%), while Janus kinase (JAK) inhibitors were also utilized (17.1%). In contrast, JAK inhibitors were less frequently used in patients aged 75 years and older (7.8%), with cytotoxic T lymphocyte antigen 4 immunoglobulin fusion proteins (CTLA4-Ig) being the most common (39.2%). JAK inhibitors and anti-interleukin-6 receptor (IL-6R) antibodies had higher continuation rates than other drugs in patients under 65 years (p < 0.001). For those aged 65-74 years, JAK inhibitors and CTLA4-Ig had higher continuation rates (p < 0.001), while among those aged 75 years and older, CTLA4-Ig and IL-6R antibodies had higher continuation rates (p < 0.001). Inadequate efficacy was the main reason for discontinuation in all age groups, while infection leading to discontinuation increased with age.

CONCLUSIONS

The study highlights the need to consider different age groups separately in elderly RA care. Among patients aged 75 years and older, abatacept and anti-IL-6R antibodies showed the highest continuation rates, suggesting their potential suitability and efficacy for this specific age cohort.

Predictive Value of the Hemoglobin-Geriatric Nutritional Risk Index in Patients with Heart Failure

Malnutrition prevails among patients with heart failure (HF), increasing the likelihood of functional decline. We assessed the predictive value of the Hemoglobin-Geriatric Nutritional Risk Index (H-GNRI)-combining hemoglobin and the Geriatric Nutritional Risk Index (GNRI)-on prognosis in older patients with HF. We used the JMDC multicenter database to examine the potential associations between malnutrition risk and other outcome measures. The patients were categorized as low- (H-GNRI score = 0), intermediate- (H-GNRI score = 1), or high-risk (H-GNRI score = 2) based on their H-GNRI scores. The primary outcome measure was the Barthel Index (BI) gain; the secondary outcomes included the BI at discharge, the BI efficiency, length of hospital stay, in-hospital mortality, discharge to home or a nursing home, and hospitalization-associated disability. We analyzed 3532 patients, with 244 being low-risk, 952 being intermediate-risk, and 2336 being high-risk patients. The high-risk group of patients had significantly lower BI values at discharge, lower BI gains, reduced BI efficiency values, and prolonged hospital stays compared to those in the low-risk group. The high-risk patients also had higher in-hospital mortality rates, lower rates of discharge to home or a nursing home, and greater incidences of a hospitalization-associated disability in comparison to the low-risk group. The H-GNRI may serve as a valuable tool for determining prognoses for patients with HF.

Types of Voluntary Work and Influence of Participation for Older Volunteers: A Systematic Review of Qualitative Studies

This systematic review synthesized findings on socio-demographic characteristics of older adults who engaged in formal volunteering, types of voluntary work for engagement, and the outcomes resulting from different types of voluntary work participation. Studies published in peer-reviewed journals were identified from six electronic databases. Studies were included if they: (1) involved a study sample of adults aged 65 and older or had a mean age of 65 , (2) reported any type of formal voluntary work at any setting, and (3) reported at least one influence of voluntary work on volunteers. Older adults who were female, married, retired, and have a higher education, fair health, and more volunteering experience participated in voluntary work. The majority of older volunteers preferred to volunteer in a community setting, and they most commonly participated in healthcare or social care related voluntary work. The older volunteers perceived positive influences mostly related to health-relatedoutcomes or helping knowledge and skills.

Self-care interventions of community-dwelling older adults: a systematic review and meta-analysis

Introduction

The current notion of "care in old age" should be reconceptualized in the ageing societies of the 21st century. Currently, "being old" means that one is actively involved in their care and has the desire to retain control and independence.

Objective

Understand and analyze the efficacy of interventions in the physical and psychological self-care practices of healthy community-dwelling older people.

Methodology

Systematic review and meta-analysis. The guidelines of the PRISMA guide were followed. The methodological quality of the studies was checked using Cochrane Effective Practice and Organisation of Care criteria, and the search was performed between 2016 and 2021.

Results

Of the 1,866 evaluated, 8 studies met the criteria. The systematic review reveals that self-care interventions focus on physical health-related variables but not on psychological variables. The meta-analysis shows that interventions significantly improve physical health-related variables (care visits, hospital admission, medication, and gait speed).

Conclusion

Self-care training programs should include psychological variables to increase health and well-being in healthy older people.

Management of Glucose-Lowering Therapy in Older Adults with Type 2 Diabetes: Challenges and Opportunities

The population of older adults (≥65 years) with type 2 diabetes mellitus (T2DM) is diverse, encompassing individuals with varying functional capabilities, living arrangements, concomitant medical conditions, and life expectancies. Hence, their categorization into different patient profiles (ie, good health, intermediate health, poor health) may aid in clinical decision-making when establishing glycemic goals and pharmacological treatment strategies. Further granularity in assessing each patient profile through interdisciplinary collaboration may also add precision to therapeutic and monitoring decisions. In this review, we discuss with a multidisciplinary approach how to deliver the best benefit from advanced diabetes therapies and technologies to older adults with T2DM according to each patient profile. There remain however several areas that deserve further research in older adults with T2DM, including the efficacy and safety of continuous glucose monitoring and automated insulin delivery systems, the switch to once-weekly insulin, the effectiveness of multidisciplinary care models, and the use of supported telemedicine and remote blood glucose monitoring in the oldest-old (≥85 years) who particularly require the assistance of others.

Association of Smoking, Diabetes, and Dialysis with the Presence of Popliteal Lesions in Femoropopliteal Artery Disease

AIM

Although recent advances in endovascular devices have markedly improved clinical outcomes of femoropopliteal endovascular therapy, lesions located in the popliteal artery are still a major challenge. This study aimed to determine the association of cardiovascular risk factors, including smoking, diabetes mellitus, and dialysis-dependent renal failure, with the location of atherosclerotic lesions in femoropopliteal artery disease.

METHODS

We used a multicenter prospective study database registering patients with symptomatic femoropopliteal artery disease undergoing drug-coated balloon treatment. The analysis included 1912 patients with de novo femoropopliteal lesions. The association of clinical characteristics with popliteal lesions was investigated using the logistic regression model. In addition, the femoropopliteal artery was divided into six segments (the proximal, middle, and distal portions of the superficial femoral artery and P1, P2, and P3 segments of the popliteal artery), and the association of clinical characteristics with the presence of atherosclerotic lesions in the respective arterial segments was investigated.

RESULTS

Smoking and dialysis-dependent renal failure showed a statistically significant inverse and positive association with the presence of popliteal lesions, respectively (adjusted odds ratio, 0.66 [95% confidence interval, 0.51-0.85] and 2.01 [1.62-2.49]; P=0.001 and P＜0.001), whereas diabetes mellitus did not (P=0.17). The subsequent per-segment analysis presented similar results.

CONCLUSIONS

Smoking was inversely associated with popliteal lesions, whereas renal failure on dialysis was positively associated in patients with symptomatic femoropopliteal artery disease who underwent drug-coated balloon treatment. Diabetes mellitus was not significantly associated.

Clinical outcomes and epidemiological characteristics of bacteremia in the older Japanese population

BACKGROUND

The characteristics and clinical consequences of bacteremia in older people, who are highly susceptible to infections, need to be clarified. This study aimed to determine the epidemiological characteristics, prognosis, and predictors of 7-day mortality in patients with community-acquired (CA), healthcare-associated (HCA), and hospital-onset (HO) bacteremia in older adults aged ≥65 years.

METHODS

Patients aged ≥65 years with positive blood cultures between April 1, 2015, and March 31, 2018, were divided into three groups: pre-old (65-74 years), old (75-89 years), and super-old (≥90 years). Characteristics based on medical exposure, including CA, HCA, and HO, were also compared and factors related to mortality were identified.

RESULTS

Overall, 1716 episodes of bacteremia were identified in 1415 patients. Of the 1211 episodes without contamination, 32.8%, 54.3%, and 12.9% occurred in pre-old, old, and super-old patients. Central line-associated bloodstream infections were more common in pre-old patients and urinary tract infections in the old and super-old. The 7-day mortality rates in the pre-old, old, and super-old groups were 7.4%, 5.8%, and 14.2% (P = 0.002), respectively. Multivariable logistic regression showed that super-old age (adjusted odds ratio, aOR: 2.09 [1.13-3.88], P = 0.019) and HO bacteremia (aOR: 1.97 [1.18-3.28], P = 0.010) were independent risk factors for 7-day mortality. Infectious disease consultation had a protective effect on 7-day mortality (aOR: 0.59 [0.35-0.99], P = 0.047).

CONCLUSIONS

The epidemiology of bacteremia differs among older people; thus, they should not be treated as a single entity. A careful approach is needed for the optimal management of bacteremia in these vulnerable patients.

Mortality and prognostic factors for spontaneous pneumothorax in older adults

Spontaneous pneumothorax occurs predominantly in young males and older adults, often as a secondary condition, and can be refractory and fatal. This study aimed to investigate the mortality and prognostic factors for pneumothorax in older patients. We retrospectively cohort studied patients with pneumothorax aged ≥65 years who visited our department from October 2012 to January 2019. Data on sex, age, medical history, smoking history, underlying lung disease, treatment, and prognosis were extracted from medical records. Cox proportional hazards regression analysis was used to investigate pneumothorax mortality and prognostic factors. In total, 239 patients were included. Among them, 36 (15%) died during hospitalization. Respiratory disease was the direct cause of death in 30 patients (83.3%), and 211 (88.3%) patients had underlying lung disease. The incidence of pneumonia in our hospital was 22.6% (54 cases). On admission, the mortality rate was 33% (18/54) in patients with concomitant pneumonia; univariate analysis showed significant differences in the Charlson Comorbidity Index (CCI), activities of daily living (ADL), and concomitant pneumonia. In the Cox proportional hazards analysis of ADL (p = 0.09), CCI (p = 0.05), and concomitant pneumonia on admission (p = 0.02), concomitant pneumonia on admission was found to be an independent predictor of in-hospital mortality. This study suggests that concomitant pneumonia at admission may be a mortality risk factor for pneumothorax.

Non-pharmacological interventions for community-dwelling older adults with possible sarcopenia or sarcopenia: a scoping review

BACKGROUND

Sarcopenia is a progressive, age-related muscle disease that, if left untreated, imposes significant personal, social, and economic burdens.

OBJECTIVE

To compile and document the nature and extent of existing studies exploring non-pharmacological interventions as a strategy to prevent or treat possible sarcopenia or sarcopenia in community-dwelling older adults.

METHOD

Thirteen databases were searched up from January 2010 to March 2023 and filters were limited to English and Chinese language. Studies with older adults (≥60 y) in the community were included. The review was conducted and reported according to the PRISMA-ScR guidance and seven stages of methodology framework. A descriptive synthesis of trial characteristics and effectiveness was conducted.

RESULTS

A total of 59 studies were included in the analysis. Most studies were RCTs. Few studies enrolled older adults with possible sarcopenia. The 70-79 age group has been studied more than any other age group. Six intervention types were identified, including exercise-only, nutrition-only, health education-only, traditional Chinese medicine-only, multicomponent intervention and control type. Majority of exercise-only interventions received resistance-based exercise. In nutrition-only category, overall food intervention or nutrients intervention was more than dietary pattern. Moreover, exercise plus nutrition was the main sub-type in multicomponent interventions. Health education-only and traditional Chinese medicine-only interventions were less frequently identified. Most studies had high and moderate compliance.

CONCLUSION

There is evidence for the effectiveness of exercise and exercise plus nutrition interventions in improving muscle strength and physical performance, whereas the effectiveness of other intervention types or their combinations requires additional research.

"Fix and flap" for an open fracture of the tibia in a 97-year-old patient: A case report of early internal fixation and free flap reconstruction

INTRODUCTION

The incidence of open fractures in super-old patients has increased. "Fix and flap" procedures using early internal fixation and free flap reconstruction in super-old patients are rarely reported.

PRESENTATION OF CASE

A 97-year-old woman presented to our emergency department after a car accident. She was diagnosed with an open fracture of the lower leg, and the open wound could not be closed after debridement. The tibia was fixed using an intramedullary nail on the day of injury, and the open wound was closed using a free latissimus dorsi myocutaneous flap on the sixth day. The flap was engrafted at the 1-year follow-up after the injury, and the patient was able to walk using a cane.

DISCUSSION

To facilitate flap elevation and shorten the operative time, a flap with fewer vascular variants should be selected, and flow-through anastomosis that does not obstruct peripheral blood flow with a high patency rate is preferable. Reconstructive free flap surgery is preferably performed within 1 week of the initial injury to prevent fibrosis or scarring of recipient vessels.

CONCLUSION

The "fix and flap" procedure, composed of early internal fixation and free flap reconstruction, is possible even in super-old patients through careful considerations of flap selection, methods of anastomosis of blood vessels, and timing of surgery. However, it is necessary to determine whether the affected limb can be preserved or amputated, and prolonged treatment must be avoided.

Physiologically based pharmacokinetic (PBPK) modelling of oral drug absorption in older adults - an AGePOP review

The older population consisting of persons aged 65 years or older is the fastest-growing population group and also the major consumer of pharmaceutical products. Due to the heterogenous ageing process, this age group shows high interindividual variability in the dose-exposure-response relationship and, thus, a prediction of drug safety and efficacy is challenging. Although physiologically based pharmacokinetic (PBPK) modelling is a well-established tool to inform and confirm drug dosing strategies during drug development for special population groups, age-related changes in absorption are poorly accounted for in current PBPK models. The purpose of this review is to summarise the current state-of-knowledge in terms of physiological changes with increasing age that can influence the oral absorption of dosage forms. The capacity of common PBPK platforms to incorporate these changes and describe the older population is also discussed, as well as the implications of extrinsic factors such as drug-drug interactions associated with polypharmacy on the model development process. The future potential of this field will rely on addressing the gaps identified in this article, which can subsequently supplement in-vitro and in-vivo data for more robust decision-making on the adequacy of the formulation for use in older adults and inform pharmacotherapy.

Differences in age-related characteristics among elderly patients with hip fractures

BACKGROUND

Incidence of hip fracture among aging patients has been increasing annually in Japan; patients aged ≤74 years may be inappropriately classified as elderly. This study aimed to identify differences in the incidence of serious perioperative complications and in-hospital, 90-day, 6-month, and 1-year mortality rates according to three age groups among patients with hip fractures.

METHODS

Patients aged ≥65 years treated for hip fracture by our multidisciplinary treatment system were included in this study. They were divided into the pre-old age (65-74 years), old age (75-89 years), and super-old age (≥90 years) groups. The baseline characteristics and outcomes of the three groups were compared, and variables associated with in-hospital, 30-day, 6-month, and 1-year mortality were analyzed.

RESULTS

In the older population, there was a higher proportion of female participants; those with trochanteric fractures, low bone mineral density, dementia, decreased walking ability and independence in performing activities of daily living; and those not living at home. Moreover, the proportion of patients with hypertension, diabetes mellitus, and circulatory disorders, American Society of Anesthesiologists Physical Status scores, and serum albumin levels significantly differed. Further, there was a significant difference in the incidence of serious complications among males and the 6-month and 1-year mortality rates among females. In addition, female patients in the pre-old age group had a higher mortality rate at any period compared with those in the old age group.

CONCLUSIONS

Patients with hip fracture who were aged 65-74, 75-89, and ≥90 years differ in terms of baseline characteristics, incidence of complications, and mortality rates. Female patients aged<75 who had fragility hip fractures potentially had worse prognosis. Our findings may be useful in preoperative explanation, postoperative management, and prognostic prediction.

Pembrolizumab as first-line treatment for advanced NSCLC in older adults: A phase II clinical trial evaluating geriatric and quality-of-life outcomes

OBJECTIVES

Since specific data on immunotherapy in older adults with advanced non-small cell lung cancer (aNSCLC) are scarce, we designed this study to determine the overall survival (OS) at one year of first-line pembrolizumab in patients older than 70 years with aNSCLC expressing PD-L1. Secondary objectives included progression-free survival, disease-specific survival, response rate, tolerability, quality of life (QoL) changes, and geriatric assessments.

MATERIALS AND METHODS

A single-arm, open-label, phase II clinical trial was carried out by the Spanish Lung Cancer Group between February 2018 and November 2019 at ten active sites in Spain. We included patients 70 years old and older with histological or cytological documented stage IIIB or IV aNSCLC and PD-L1 expression ≥ 1%. Each subject received 200 mg of intravenous pembrolizumab every three weeks for a maximum of two years.

RESULTS

83 patients were recruited for the study and 74 were finally analysed. Most were male (N = 64, 86.5%) and former smokers (N = 51, 68.9%). 24 patients (32.4%) completed at least one year of treatment, 62 (83.7%) discontinued treatment, and 30 (40.5%) experienced disease progression. The median follow-up of our cohort was 18.0 months [range: 0.1-47.7] and 46 patients (62.2%) died during the period of study. The estimated OS at one year was 61.7% (95% CI: 49.6-71.8%) and the median OS of our cohort was 19.2 months (95% CI: 11.3-25.5). QoL tended to improve throughout the study, although the differences were not statistically significant. The main geriatric scores remained stable, except for a worsening in nutritional status (P = 0.004) and an improvement in frailty (P = 0.028).

CONCLUSION

Our results support treating older adults with aNSCLC expressing PD-L1 with pembrolizumab in monotherapy. The stability of most geriatric scores and the positive trend on the patients' QoL should be highlighted, although our results did not reach statistical significance.
