#2576 Effect of dialysis versus conservative care on all-cause mortality in older patients with advanced CKD: nationwide Swedish cohort study

Abstract Background and Aims Conservative care is emerging as an alternative to dialysis in older patients with advanced chronic kidney disease (CKD). However, high-quality evidence comparing the effect of dialysis versus conservative care on patient survival is lacking. Previous observational studies suffered from avoidable biases, such as immortal time bias and lead time bias, and adjusted for limited confounders. This study aimed to assess the effects of dialysis versus conservative care on mortality in older patients with advanced CKD. Method The target trial emulation framework was used to design and analyze this observational study. We conducted a nationwide observational cohort study using data from the Swedish Renal Registry between 2007-2021. We included all nephrologist-referred patients with eGFR < 20 ml/min/1.73 m2 who had a registered decision for dialysis or conservative care. Eligible patients were required to be ≥ 65 years with a Davies Comorbidity Score ≥ 2 or ≥ 80 years. The primary endpoint was 5-year all-cause mortality. Inverse probability of treatment weighting was used to adjust for 50 baseline confounders, including demographics, comorbidities, medication use, blood pressure, laboratory measurements, hospitalizations, and calendar year. Patients in the non-overlapping region of the propensity score distribution were excluded since they had an absolute indication for dialysis or conservative care. Cox proportional hazards regression was used to estimate intention-to-treat hazard ratios (HRs) with 95% confidence intervals (CIs), and the Kaplan-Meier estimator was used to estimate absolute risks. Additionally, we calculated the 5-year restricted mean survival times (RMST) and the 5-year RMST difference between dialysis and conservative care arms. To test the robustness and consistency of our main results, we performed a subgroup analysis in patients aged ≥80. Results Of 2834 eligible patients, 1903 had a registered choice for dialysis and 931 for conservative care. The median age was 81 years, 36.1% were female and median eGFR was 13.1 ml/min/1.73 m2. During the 5-year follow-up period, 29 conservative care patients started dialysis and 430 patients died before starting dialysis. After weighting, all confounders were balanced (standardized mean difference < 0.10). Compared to dialysis, conservative care was associated with a higher absolute 5-year risk of death (91.8% vs. 74.1%), corresponding with an absolute risk difference of 17.6% (95% CI 13.3%-21.9%) (Fig. 1). The adjusted hazard ratio for conservative care vs. dialysis was 2.3 (95% CI 2.0-2.6). The 5-year restricted mean survival times were 34.8 (95% CI 33.2-37.3) months for dialysis and 21.5 (95% CI 19.4-23.6) months for conservative care groups. The 5-year RMST difference was 13.3 months (95% CI 10.8-16.6), meaning that dialysis patients would live on average 13.3 months longer over a 5-year follow-up period than conservative care patients (Table 1). The results were consistent among people ≥ 80 years (adjusted HR 2.2, 95% CI 1.9-2.5; 5-year RMST difference 9.4 months, 95% CI 7.2-13.9). Conclusion In older patients with advanced CKD under nephrologist care, conservative care was associated with a higher risk of mortality than dialysis. These findings could improve the shared decision-making process with patients on the choice of kidney failure treatment.

Combined Systemic Immune-inflammatory Index (SII) and Geriatric Nutritional Risk Index (GNRI) predict survival in elderly patients with hip fractures: a retrospective study

PurposeThe Systemic Immune-inflammatory Index (SII) and Geriatric Nutritional Risk Index (GNRI) have undergone comprehensive examination and validation in forecasting the outcomes of diverse medical conditions. Nevertheless, the correlation between the combined use of GNRI and SII metrics and hip fractures has yet to be elucidated. This study aimed to determine whether the amalgamation of SII and GNRI scores constitutes an independent prognostic factor for elderly patients with hip fractures.MethodsWe conducted a retrospective analysis of elderly patients admitted to our facility with hip fractures, encompassing both femoral neck and intertrochanteric fractures. Demographic information, experimental parameters, and postoperative complications were systematically recorded. The Geriatric Nutritional Risk Index (GNRI) and Systemic Immunoinflammatory Index (SII) were meticulously computed. Receiver operating characteristic (ROC) curves were generated, and optimal cutoff values for each parameter were determined. Subsequently, a multivariate Cox regression analysis was employed to assess the predictive utility of the SII–GNRI score in relation to 1-year postoperative mortality among elderly patients with hip fractures.ResultsIn a study involving 597 patients, 90 of whom experienced mortality within 1 year, it was observed that the SII-GNRI score in the group of patients who passed away was significantly higher compared to the group that survived. Following a multifactorial adjustment, it was established that a high SII–GNRI score served as an independent predictor of 1-year all-cause mortality in older patients with hip fractures. In addition to the SII–GNRI score, factors such as length of hospital stay, CCI > 2, and blood transfusion were also identified as independent risk factors for survival. Notably, the incidence of postoperative complications in patients with high SII–GNRI scores was significantly greater than in patients with low scores.ConclusionThe SII–GNRI score proves valuable in predicting the 1-year survival rate for elderly patients with hip fractures who have undergone surgery.

Impact of nurse-led interprofessional work in older patients with heart failure and multimorbidity: A retrospective cohort study

BackgroundThe number of patients with multimorbidity has increased due to the aging of the global population. Although the World Health Organization has indicated that multimorbidity will be a major medical problem in the future, the appropriate interventions for patients with multimorbidity are currently unknown. This study aimed to investigate whether nurse-led interprofessional work is associated with improved prognosis in heart failure patients with multimorbidity aged ≥65 years who were admitted in an acute care hospital. MethodsPatients who were admitted to the cardiovascular medicine ward of an acute care hospital in Osaka, Japan, and underwent nurse-led interprofessional work from April 1, 2017 to March 31, 2020, and from April 1, 2014 to March 31, 2016, were included in this retrospective cohort study. The patients were matched by age, sex, and New York Heart Association classification. The nurse-led interprofessional work was based on a three-step model that incorporates recommendations from international guidelines for multimorbidity. The primary outcome was all-cause mortality. ResultsThe mean age of the participants was 80 years, and 62 % were men. The nurse-led interprofessional work group showed a significant difference in all-cause mortality compared with the usual care group (hazard ratio, 0.45; 95 % confidence interval [CI], 0.29–0.69; P < 0.001). Compared with the usual care group, the nurse-led interprofessional work group exhibited a 7 % difference in mortality rate at 1-year post-discharge (P < 0.001). ConclusionsNurse-led interprofessional work may reduce the all-cause mortality in older patients with heart failure and multimorbidity.

Reduced-Dose Rivaroxaban Is Associated with Lower All-Cause Mortality in Older Patients with Nonvalvular Atrial Fibrillation.

Reduced-dose rivaroxaban (10 mg) was used in the J-ROCKET AF trial, demonstrating safety in the Asian population. It remains unclear whether treatment with reduced-dose versus full-dose rivaroxaban (20 mg/15 mg) is associated with all-cause mortality in older patients with nonvalvular atrial fibrillation. Proposed: To evaluate the effects of reduced-dose rivaroxaban on all-cause mortality in patients over 85. We retrospectively enrolled medical records representing the period from October 2012 to November 2016. The 2 × 2 factorial design incorporated age (≥85 vs. <85) and rivaroxaban use (reduced vs. full dose). The primary study outcomes were all-cause and cardiac-related mortality. The study enrolled 2386 patients with a mean age of 76.6 ± 10.4 years; 51.8% were male. In the ≥85 group (n = 593), the reduced-dose subgroup had lower all-cause (5.3% vs. 10.6%, p = 0.02) and cardiac-related mortality (1.9% vs. 5.1%, p = 0.04), whereas the younger patients receiving reduced-dose rivaroxaban had higher all-cause mortality (3.7% vs. 1.8%, p = 0.01) but no difference in cardiac-related mortality (1.2% vs. 0.7%, p = 0.33). The rate of hospitalization for heart failure was significantly lower in the elderly group with reduced-dose rivaroxaban (7.2% vs. 15.7%, p < 0.01) but not in the younger group. After adjusting for confounders in the older group, treatment with reduced-dose rivaroxaban was associated with lower risk of all-cause mortality (adjusted HR (aHR): 0.40, 95% CI: 0.21-0.74, p < 0.01) and hospitalization for heart failure (aHR: 0.54, 95% CI: 0.29-0.99, p = 0.05). No associations were found between rivaroxaban dose and cardiac-related mortality in either group, nor between younger age and any outcome. Reduced-dose rivaroxaban was associated with lower risks of all-cause mortality and hospitalization for heart failure in older patients with nonvalvular atrial fibrillation. Future studies can investigate the effect of reduced-dose rivaroxaban on prognoses in elderly individuals ≥85 years in the west.

The risk of malnutrition and its clinical implications in older patients with cancer.

Malnutrition is a common geriatric syndrome with multiple negative outcomes including mortality. However, there is a scarcity of literature that focuses on the relationship between malnutrition risk and its clinical implications on geriatric syndromes and mortality among cancer patients. The aim of this study is to determine the clinical importance of malnutrition risk in geriatric oncology practice. 180 patients with cancer who were ≥ 65years were included in the study. All patients were questioned in terms of geriatric syndromes, including polypharmacy, frailty, probable sarcopenia, fall risk, dynapenia, depression, cognitive impairment, insomnia, and excessive daytime sleepiness. Mini Nutritional Assessment scores > 23.5 and 17-23.5 were categorized as well-nourished and malnutrition risk, respectively. Of the 180 patients (mean age 73.0 ± 5.6years, female: 50%), the prevalence of malnutrition risk was 28.9%. There was no statistically significant difference between the groups in terms of age, gender, education, marital status, body mass index, and comorbidities except for chronic obstructive pulmonary disease (p > 0.05). After adjustment for age, sex, and body mass index; polypharmacy (odds ratio [OR]: 3.17; 95% confidence interval [CI], 1.48-6.81), reduced calf circumference (OR: 3.72; 95% CI, 1.22-11.38), fall risk (OR: 2.72; 95% CI, 1.03-7.23), depression (OR: 6.24; 95% CI, 2.75-14.18), insomnia (OR: 4.89; 95% CI, 2.16-11.05), and frailty (OR: 2.44; 95% CI, 1.75-3.40) were associated with malnutrition risk compared to well-nourished patients (p < 0.05). Median survival in patients with malnutrition risk was 21.3months (range 14.1-28.4 95% CI) and median survival in patients who were defined as well nourished was not reached (p < 0.001). The risk of malnutrition was associated with a higher risk for all-cause mortality in older patients with cancer, and was associated with many geriatric syndromes, including polypharmacy, fall risk, frailty, insomnia, and depression.

The Impact of Contrast-Associated Acute Kidney Injury on All-Cause Mortality in Older Patients After Coronary Angiography:A 7.5-year Follow-Up.

Older patients (≥75years) after coronary angiography constitute an increasing proportion, but only limited data are available regarding the prognosis of geriatric contrast-associated acute kidney injury (CA-AKI). Patients (≥75years) undergoing coronary angiography between December 2010 and September 2013 were consecutively enrolled. CA-AKI was defined as an increase in serum creatinine of 25% or .5mg/dL from the baseline within 48-72h of contrast exposure. All-cause mortality was assessed during median 7.5years (interquartile range [IQR] 6.7-8.7years) follow-up period. In total, 571 patients aged >75years undergoing coronary angiography were enrolled in a single center study; 82 (14.4%) patients had CA-AKI. The all-cause mortality during the median 7.5years follow-up period was 22.0% in patients with CA-AKI and 13.1% in patients without CA-AKI (P = .015). After adjusting for potential confounding factors, the multivariable analysis indicated that CA-AKI was related to an increased risk of all-cause mortality during the median 7.5-year follow-up (hazard ratio [HR]: 2.46; 95% CI: 1.29-4.7; P = .006). CA-AKI is a significant and independent predictor of long-term mortality for patients aged over 75years who underwent coronary angiography.

ObjectivesMalnutrition in cancer-free older patients receiving home medical care may affect prognosis, but indicators of long-term nutrition-related prognosis have not been developed. This study investigated the utility of the Controlling...

Disparities in All-Cause Mortality in Older Patients with Colorectal Cancer According to Disability Status: A Nationwide Analysis.

Background: Although investigating patterns of cancer mortality is important in understanding the effect of cancer on population health, knowledge regarding mortality in cancer patients with disability is scarce. This study examined the association between disability status and all-cause mortality in older patients with colorectal cancer. Methods: Data were obtained from the 2008–2019 National Health Insurance Service claims data. The study population included patients with colorectal cancer aged 60 years or above. The outcome measure was all-cause 5-year and overall mortality. A survival analysis was performed using the Cox proportional hazards model to analyze the association between all-cause mortality and disability status. Subgroup analysis was conducted based on disability severity. Results: The study population consisted of 6340 patients, and disability was reported in 15.8% of the included individuals. Participants with disability had a higher risk of both all-cause 5-year (hazard ratio (HR) 1.21, 95% confidence interval (95% CI) 1.07–1.37) and overall mortality (HR 1.15, 95% CI 1.03–1.28). These findings were particularly significant in individuals with severe rather than mild disability. Conclusion: Older colorectal cancer patients with disabilities showed a higher risk of overall and 5-year all-cause mortality, which was evident in individuals with severe disabilities. The findings indicated disparities in mortality according to disability status. Further, we suggest that policies that can mediate such disparities must be strengthened.

Muscular Calf Vein Thrombosis Is Associated With Increased 30-Day Mortality But Not 90-Day Mortality in Older Patients With Hip Fracture

Calf deep vein thrombosis (DVT) is common in patients with hip fractures. However, studies on whether calf DVT has an impact on the prognosis are limited. This retrospective cohort study explored the association between calf DVT and 30-day and 90-day all-cause mortality in older patients with hip fractures. A total of 564 consecutive patients who underwent ultrasound examination were identified from our hip fracture database and categorized into patients with calf DVT (axial DVT, muscular DVT) and no DVT. Of these, 86 patients (15.2%) had ultrasound-confirmed calf DVT, including 66 patients with muscular DVT, and 20 patients with axial DVT. The 30-day and 90-day all-cause mortality were 2.5% and 6.0%, respectively. Multivariate Cox analysis showed that calf DVT was significantly associated with an increased risk of 30-day mortality (hazard ratio [HR] 3.21, 95% confidence interval [CI] 1.05 to 9.84, p=0.04), but this risk relationship did not persist at 90-day follow-up (HR 1.59, 95% CI 0.69 to 3.71, p=0.28). When calf DVT was further categorized, muscular DVT remained an independent risk factor for 30-day mortality (HR 3.95, 95% CI 1.18 to 13.15, p=0.03), whereas this relationship was not found in axial DVT (HR 1.79, 95% CI 0.21 to 15.02, p=0.59). In conclusion, calf DVT, especially muscular calf DVT but not axial DVT, is independently associated with an increased risk of 30-day mortality in older patients with hip fracture, but this risk relationship did not persist at 90-day follow-up.

Association between Serum Cystatin C levels and long-term cardiovascular outcomes and all-cause mortality in older patients with obstructive sleep apnea.

Background and Aims: To investigate the association between obstructive sleep apnea (OSA) severity and baseline serum cystatin C (Cys-C) concentration and to explore the association between baseline serum Cys-C and long-term cardiovascular outcomes and mortality in older patients with OSA. Methods: Between January 2015 and October 2017, a total of 1107 consecutive eligible older patients (≥60 years) with OSA were included in this multicenter, prospective cohort study, and baseline demographics, clinical characteristics, sleep parameters, and follow-up outcomes were collected. Participants were divided into different groups based on baseline serum Cys-C levels. The primary end point was major adverse cardiovascular events (MACE) and the secondary end point was all-cause mortality. The correlation between OSA severity and baseline serum Cys-C was evaluated by Spearman correlation analysis. Multivariate Cox regression was used to analyze the association between Cys-C and the incidence of MACE and mortality. Results: Participants included 672 men and 435 women, with a median age of 66 (range, 60–96) years. At baseline, apnea–hypopnea index (AHI) (r = 0.128, p < 0.05), oxygen desaturation index (ODI) (r = 0.116, p < 0.05), and the lowest pulse oxygen saturation (LSpO2) (r = −0.097, p < 0.05) were correlated with serum Cys-C concentration. During the median follow-up period of 42 months, 97 patients (8.8%) experienced MACE and 40 patients (3.6%) experienced death. The association between serum Cys-C levels and the risk of MACE and all-cause mortality was slow rising shaped. The multivariable Cox regression analysis showed patients with a serum Cys-C concentration of ≥1.14 mg/L had higher risks of MACE (HR = 5.30, 95% CI: 2.28–12.30, p < 0.05) and all-cause mortality (HR = 9.66, 95% CI: 2.09–44.72, p < 0.05) compared with patients with serum Cys-C of ≤0.81 mg/L in older patients with OSA. The receiver-operating characteristic curve showed baseline serum Cys-C levels exhibited moderately capable of identifying patients with a long-term risk of clinical adverse events (MACE and mortality). Conclusion: OSA severity was positively correlated with serum Cys-C concentration. High levels of Cys-C were independently associated with increased risks of MACE and all-cause mortality in older patients with OSA, suggesting that lowering Cys-C levels should be considered as a therapeutic target, and monitoring serum Cys-C may be beneficial to the favorable prognosis of older patients with OSA.

Cognitive Domain Impairment and All-Cause Mortality in Older Patients Undergoing Hemodialysis

The highly prevalent cognitive impairment in hemodialysis patients is associated with all-cause mortality; however, the role of different cognitive domain impairments in this association is still not clarified. Our objective was to determine the association between cognitive domain impairment and all-cause mortality in elderly adult patients undergoing hemodialysis. We conducted a prospective cohort study including patients from 11 hemodialysis centers in Beijing. Baseline data were collected, and a series of neuropsychological batteries covering 5 domains of cognitive function were included for the assessment of cognitive function. According to the fifth version of the Diagnostic and Statistical Manual of Mental Disorders criteria (DSM-V), the patients were classified as normal, mild, and major cognitive impairment for global and domain cognitive function, then followed up for 1 year. Kaplan–Meier survival analysis was used to compare the difference in the cumulative survival rate in different cognitive domains. A multivariate Cox proportional hazards regression analysis was used to determine the association between global or domain cognitive impairment and all-cause mortality. A total of 613 patients were enrolled, the mean age was 63.82 ± 7.14 years old, and 42.1% were women. After 49.53 ± 8.42 weeks of follow-up, 69 deaths occurred. Kaplan–Meier plots demonstrated a significant association of cognitive impairment in memory, executive function, attention, and language domains with all-cause death. Multivariate Cox regression analysis showed that mild and major impairment of global cognition (HR = 2.89 (95% CI, 1.01–8.34), p = 0.049 and HR = 4.35 (95% CI, 1.55–12.16), p = 0.005, respectively), executive cognitive domain (HR = 2.51 (95% CI, 1.20–5.24), p = 0.014; HR = 3.91 (95% CI, 1.70–9.03), p = 0.001, respectively), and memory cognitive domain (HR = 2.13 (95% CI, 1.07–4.24), p = 0.031; HR = 3.67 (95% CI, 1.71–7.92), p = 0.001, respectively) were associated with all-cause mortality. Combined impairment of 3, 4, and 5 cognitive domains was associated with all-cause mortality [HR = 5.75 (95% CI, 1.88–17.57), p = 0.002; HR = 12.42 (95% CI, 3.69–41.80), p < 0.001; HR = 13.48 (95% CI, 3.38–53.73), p < 0.001, respectively]. We demonstrate an association between the executive and memory cognitive domain impairment and all-cause mortality in hemodialysis patients. Our data suggest that the impairments in these cognitive domains might help in the early identification of hemodialysis patients at risk of death.

Day-To-Day Home Blood Pressure Variability and All-Cause Mortality in a Memory Clinic Population.

Background:High day-to-day blood pressure variability (BPV) has been associated with an increased risk for cognitive decline and mortality in the general population. Whether BPV is associated with increased all-cause mortality in older people with cognitive impairment is unknown.Objective:To investigate the association between day-to-day home BPV and all-cause mortality in older patients attending a memory clinic.Methods:We included 279 patients attending a memory clinic, who measured home blood pressure (BP) for 7 consecutive days in the morning and evening. Within-subject BPV was defined as the variation independent of the mean (VIM). Time-to-death was verified through the Dutch population registry. Cox proportional hazard regression was used. Separate analyses were performed for morning-to-morning and evening-to-evening BPV.Results:Mean age was 73±9 years, dementia and mild cognitive impairment were diagnosed in 35% and 34% respectively, and mean home BP was 139/79 mmHg. After a mean follow-up of 3.2 years, 52 patients had died. Neither day-to-day systolic nor diastolic VIM were associated with mortality (adjusted hazard ratio [HR] systolic VIM: 0.99, 95% -CI 0.92–1.06, p = 0.770, HR diastolic VIM: 1.04, 95% -CI 0.93–1.17, p = 0.517). When morning and evening measurements were analyzed separately, systolic morning-to-morning VIM was associated with mortality (adjusted HR: 1.09, 95% -CI 1.01–1.18, p = 0.033).Conclusion:In this study, day-to-day BPV was not associated with all-cause mortality in patients attending a memory clinic. However, morning-to-morning BPV was. Due to the short assessment window, there is still a lack of clarity; hence future research is warranted to clarify the role of all BPV components in aging.

Comparative effectiveness of cardiac resynchronization therapy in older patients with heart failure: Systematic review and meta-analysis

BackgroundPivotal CRT trials enrolled patients with HFrEF significantly younger than the typical contemporary patient with HFrEF. Thus, the risks and benefits in this older population with HFrEF are largely unknown. We sought to perform meta-analyses comparing safety and effectiveness of cardiac resynchronization therapy (CRT) in older vs younger patients with heart failure with reduced ejection fraction (HFrEF). Methods and ResultsPubMed, The Cochrane Library, Scopus, and Web of Science were queried for comparative effectiveness studies of CRT in older patients with HFrEF. Title, abstract, and full-text screening was performed to identify studies comparing at least 1 prespecified end point between older and younger adult patients with at least 50 participants. Random effects meta-analysis in the left ventricular ejection fraction (LVEF) mean difference (older minus younger) and the relative risk (RR) of death, improvement in New York Heart Association (NYHA) functional class, and complications are reported along with estimates of heterogeneity. In 7 studies, there was similar LVEF improvement between groups (mean difference 1.14, 95% confidence interval [CI] –0.04 to 2.32, P = .06, I2 = 53%). Older patients were equally likely as younger patients to see an improvement in NYHA functional class of at least 1 in 6 studies (RR 0.99, 95% CI 0.93–1.06, P = .76, I2 = 25%). No significant differences in the incidence of hematoma, pneumothorax, lead dislodgment, cardiac perforation, or infection requiring explant was observed. The RR of mortality in 11 studies demonstrated higher risk of all-cause mortality in older patients (RR 1.05, 95% CI 1.03–1.08, P < .01, I2 = 0%). ConclusionsCompared with younger patients, older patients receiving CRT were equally likely to experience improvement in LVEF, left ventricular end-diastolic diameter, and NYHA functional class. There was no difference in procedural complications. The higher rate of all-cause mortality in older patients likely reflects a greater underlying risk of death from competing causes.

Aspartate aminotransferase to alanine aminotransferase ratio is associated with frailty and mortality in older patients with heart failure

Frailty is a common comorbidity associated with adverse events in patients with heart failure, and early recognition is key to improving its management. We hypothesized that the AST to ALT ratio (AAR) could be a marker of frailty in patients with heart failure. Data from the FRAGILE-HF study were analyzed. A total of 1327 patients aged ≥ 65 years hospitalized with heart failure were categorized into three groups based on their AAR at discharge: low AAR (AAR < 1.16, n = 434); middle AAR (1.16 ≤ AAR < 1.70, n = 487); high AAR (AAR ≥ 1.70, n = 406). The primary endpoint was one-year mortality. The association between AAR and physical function was also assessed. High AAR was associated with lower short physical performance battery and shorter 6-min walk distance, and these associations were independent of age and sex. Logistic regression analysis revealed that high AAR was an independent marker of physical frailty after adjustment for age, sex and body mass index. During follow-up, all-cause death occurred in 161 patients. After adjusting for confounding factors, high AAR was associated with all-cause death (low AAR vs. high AAR, hazard ratio: 1.57, 95% confidence interval, 1.02–2.42; P = 0.040). In conclusion, AAR is a marker of frailty and prognostic for all-cause mortality in older patients with heart failure.

A systematic review of the novel applications of cannabinoids in dementia care: food refusal and neuropsychiatric symptoms

<h3>Introduction</h3> In recent years, there has been increased research interest investigating the novel use of cannabinoids in the treatment of patients living with dementia. Early clinical research suggests that cannabinoids may be beneficial in a variety of areas, including pain, sleep, weight loss, and behavioral aggression. In particular, cannabinoids may be especially valuable in dementia care in areas where there are currently limited therapies, including food refusal and neuropsychiatric symptoms (NPS) such as agitation and sleep disruption. Pharmacologic interventions for disordered eating in dementia are limited. And although atypical antipsychotics are commonly used to treat NPS, they are associated with an increased risk of serious adverse events and all-cause mortality in older patients. Thus, this study aims to review the current literature on the potential applications of cannabinoids in the treatment of food refusal and neuropsychiatric symptoms in dementia populations. <h3>Methods</h3> A systematic literature review was performed utilizing six major electronic databases (PubMed, MEDLINE, EMBASE, PsycINFO, Google Scholar, Cochrane CENTRAL) for articles published from database inception to November 2020. Search strings including keywords and Medical Subject Headings (MeSH terms) related to cannabinoids, dementia, food refusal, weight loss, agitation, and neuropsychiatric symptoms were used to identify relevant articles. <h3>Results</h3> A total of 23 relevant articles were identified that examined the use of cannabinoids including tetrahydrocannabinol, dronabinol, and nabilone in dementia patients. Regarding treatment of NPS in dementia, numerous studies found that use of cannabinoids was associated with potential benefits including reduced nighttime motor activity, improved sleep duration, reduced agitation, and lower Neuropsychiatric Inventory scores. With regards to food refusal, multiple articles documented use of cannabinoids being associated with increased percentage of meals consumed, with one crossover placebo-controlled trial finding increased overall body weight in dementia patients on dronabinol. Documented potential side effects include possible worsening of psychosis and anxiety, although overall, the literature appears to show cannabinoids to be generally well-tolerated. <h3>Conclusions</h3> Use of cannabinoids as potential treatments for food refusal and neuropsychiatric symptoms in dementia populations is an ongoing area of research. Completed clinical studies done on the subject to date have been small in scale, but have shown cannabinoids to be relatively well-tolerated and have yielded positive results. Thus, cannabinoids may have potential as a therapeutic intervention in dementia care, and these findings warrant further investigation. <h3>Funding</h3> Not applicable

The Rate of Coronary Angiography Refusal in Older Patients with Non-ST Elevation Acute Coronary Syndrome and Its Impact on All-Cause Mortality.

Objectives:Significant number older patients with acute coronary syndrome (ACS) cannot undergo coronary angiography (CAG) due to various comorbidities. Patient’s refusal of invasive procedures is common among old patients and has not been thoroughly investigated in the context of ACS. We wanted to assess CAG refusal rate and its impact on all-cause mortality in older patients with non-ST elevation acute myocardial infarction.Methods:In this retrospective study, patients over 75 years of age admitted with acute non-ST elevation ACS were included in the study. Patients were divided into three groups based on the treatment strategy; Group 1: Those who underwent CAG; Group 2: Refused; and Group 3: Deemed unsuitable for procedure due to severe comorbidities. The primary outcomes were to assess the patient refusal rate and its impact on all-cause mortality.Results:The study included 201 elderly patients. Eighty-two (41%) patients did not undergo CAG and of those, 48 (24%) had severe comorbidities, and 34 (17%) refused the procedure. The in-hospital mortality for patients who underwent, refused, or could not undergo CAG was 5.0%, 0%, and 16.7% (p<0.01); 30-day mortality 8.5%, 9.1%, and 25% (p=0.01); and long-term mortality was 20.2%, 35.3%, and 47.9% (p<0.01), respectively. The median follow-up was 12 months. Hazard ratio of treatment refusal for long-term mortality was 1.97 (1.02–3.87, 95% CI).Conclusion:Substantial number of elderly patients with ACS refuses to undergo CAG and this leads to increased mortality. Factors affecting patient behavior and the decision-making process should be explored.

Risk factors associated with 28-day all-cause mortality in older severe COVID-19 patients in Wuhan, China: a retrospective observational study

We aimed to analyse clinical characteristics and identify risk factors predicting all-cause mortality in older patients with severe coronavirus disease 2019 (COVID-19). A total of 281 older patients with severe COVID-19 were categorized into two age groups (60–79 years and ≥ 80 years). Epidemiological, clinical, and laboratory data, and outcome were obtained. Patients aged ≥ 80 years had higher mortality (63.6%) than those aged 60–79 years (33.5%). Anorexia and comorbidities including hypertension, diabetes and COPD, higher levels of lactate dehydrogenase (LDH), osmotic pressure, C-reactive protein, D-dimer, high-sensitivity troponin I and procalcitonin, and higher SOFA scores were more common in patients aged > 80 years than those aged 60–79 years and also more common and higher in non-survivors than survivors. LDH, osmotic pressure, C-reactive protein, D-dimer, high-sensitivity troponin I, and procalcitonin were positively correlated with age and sequential organ failure assessment (SOFA), whereas CD8+ and lymphocyte counts were negatively correlated with age and SOFA. Anorexia, comorbidities including hypertension, diabetes, and chronic obstructive pulmonary disease (COPD), LDH, osmotic pressure, and SOFA were significantly associated with 28-day all-cause mortality. LDH, osmotic pressure and SOFA were valuable for predicting 28-day all-cause mortality, whereas the area under the receiver operating characteristic curve of LDH was the largest, with sensitivity of 86.0% and specificity of 80.8%. Therefore, patients with severe COVID-19 aged ≥ 80 years had worse condition and higher mortality than did those aged 60–79 years, and anorexia and comorbidities including hypertension, diabetes, COPD, elevated plasma osmotic pressure, LDH, and high SOFA were independent risk factors associated with 28-day all-cause mortality in older patients with severe COVID-19. LDH may have the highest predictive value for 28-day all-cause mortality in all examined factors.

J-curve relationship between admission SBP and 2-year cardiovascular mortality in older patients admitted for acute coronary syndrome.

Objective:To investigate the relationship between admission SBP and subsequent cardiovascular and all-cause mortality in older patients hospitalized for acute coronary syndrome (ACS).Methods:This is a retrospective observational study. Data from the CBD Bank (Cardiovascular Center Beijing Friendship Hospital Database Bank) were used to analyze the cardiovascular and all-cause mortality during hospitalization and over the follow-up period in relation to admission SBP among patients aged at least 65 years admitted for ACS from December 2012 through July 2019. Results were presented according to SBP quartiles: Q1, less than 120 mmHg; Q2, from 120 to 129 mmHg; Q3, from 130 to 143 mmHg; and Q4, at or above 144 mmHg.Results:A total of 6785 patients were included in this cohort study. Mean (SD) patient age was 74.0 (6.5) years, and 47.6% were women. Mean (SD) follow-up time was 2.54 (1.82) years. A nonlinear relation was observed between SBP at admission and cardiovascular and all-cause mortality during hospitalization and over the follow-up period using restricted cubic splines. After adjustment for potential confounders, patients in Q1 had higher risk for 2-year cardiovascular death by Cox proportional hazard model compared with patients in Q2 [hazard ratio, 1.58; 95% confidence interval (CI), 1.12–2.21, P = 0.009], whereas patients in Q3 or Q4 exhibited a trend towards increased risk for 2-year cardiovascular death (hazard ratio, 1.33, 95% CI, 0.95–1.86, P = 0.094, for Q3 vs. Q2; and hazard ratio, 1.28, 95% CI, 0.91–1.82, P = 0.160, for Q4 vs. Q2). Meanwhile, when compared with patients in Q1, patients in Q2 had lower risk for 2-year cardiovascular death (hazard ratio, 0.64; 95% CI, 0.45–0.89, P = 0.009) whereas patients in Q3 or Q4 had similar risk for cardiovascular death (hazard ratio, 0.85, 95% CI, 0.63–1.14, P = 0.272, for Q3 vs. Q1; and hazard ratio, 0.82, 95% CI, 0.59–1.13, P = 0.221, for Q4 vs. Q1). However, low-admission SBP was not an independent predictor of 2-year all-cause mortality in this population.Conclusion:Among patients aged at least 65 years admitted for ACS, there is a J-curve relationship between supine admission SBP and risk for 2-year cardiovascular death, with a nadir at 120–129 mmHg.

Malnutrition and overall survival in older patients with cancer

In this study, we assessed the prevalence of malnutrition and its association with overall survival among patients with cancer aged 65 years and older. In this retrospective cohort study, patients receiving cancer care underwent a comprehensive geriatric assessment (CGA). Malnutrition status was determined through the CGA. We used univariate and multivariable Cox regression survival analyses to assess the association between baseline malnutrition and survival. A total of 454 patients with cancers were included in the analysis. The median age was 78 years and men and women were equally represented. Forty-two percent (n=190) were malnourished at baseline, and 33% died during the follow-up (range 0.2-51.1 month). Univariate analysis showed that malnutrition increased the risk of all-cause mortality in older patients with cancer (HR, 1.49; 95% CI, 1.08-2.05; p=0.01). In the multivariate Cox regression model, malnutrition increased the risk of all-cause mortality (HR, 1.87; 95% CI, 1.10-3.17; p=0.02) in older patients with solid tumors. However, malnutrition did not increase the risk of all-cause mortality for hematologic malignancies. In our study, we found that malnutrition was a risk factor for mortality in older cancer patients, especially in older patients with solid tumors. Prospective inter ventional studies are recommended.

Hospital-Acquired Functional Decline and Clinical Outcomes in Older Patients Undergoing Transcatheter Aortic Valve Implantation.

This study aimed to assess the relationship between hospital-acquired functional decline and the risk of mid-term all-cause death in older patients undergoing transcatheter aortic valve implantation (TAVI).Methods and Results:In total, 463 patients (mean age 85 years, interquartile range [IQR]: 82, 88) undergoing elective TAVI at Sakakibara Heart Institute between 2010 and 2018, who were followed up for 3 years, were enrolled in the study. Hospital-acquired functional decline after TAVI, which was defined by at least a 1-point decrease on the Short Physical Performance Battery before discharge compared to the preoperative score, was assessed. A total of 113 patients (24.4%) showed hospital-acquired functional decline after TAVI, and 50 (11.3%) patients died over a mean follow-up period of 1.9±0.8 years. Kaplan-Meier survival curves indicated that hospital-acquired functional decline was significantly associated with all-cause mortality (log-rank test, P=0.001). On multivariate Cox regression analysis, hospital-acquired functional decline was associated with a higher risk of all-cause mortality (OR 2.108, 95% CI 1.119-3.968, P=0.021) independent of sex, body mass index, advanced chronic kidney disease, and preoperative frailty, as assessed by the modified essential frail toolkit. Hospital-acquired functional decline is associated with mid-term all-cause mortality in older patients following TAVI. Trajectory of functional status is a vital sign, and it is useful for risk stratification in older patients following TAVI.
