PO-01-227 CATHETER ABLATION OUTCOMES OF ATRIAL FIBRILLATION IN ELDERLY AND VERY ELDERLY PATIENTS

Age is a non-modifiable risk factor of atrial fibrillation (AF). To assess the efficacy and safety of catheter ablation in the Elderly and Very Elderly population. All patients undergoing AF ablation (2013-2021) with available data on follow-up were analyzed. Primary endpoint was AF recurrence based on patients reported outcomes and electrocardiographic documentation. Patients were divided into 3 groups according to age at ablation; Non-Elderly (<65 years), Elderly (≥65 <75 years) and Very Elderly (≥75 years). Baseline and 1-year patient surveys were used to estimate AF severity score (AFSS) as well as AF burden (mean of AF duration score and AF frequency score; scale 0: no AF to 10: continuous with 9 frequencies/durations in between). A total of 7020 patients were included (42% Non-Elderly, 42% Elderly and 16%Very Elderly). Periprocedural major complications were low (<1%). Pericardial effusion was very uncommon but more frequent with older age (Non-Elderly 3 (0.1%); Elderly 15 (0.5); Very Elderly 6 (0.5%); p<0.05). In all patients, a direct relationship was seen between AF recurrence and increase in age. However there was an interaction between age group and AF type. At 3 years, AF recurrence after ablation for persistent atrial fibrillation (PersAF) was the highest in very elderly group (36%), followed by the Elderly group (30%) and was the lowest in the non-Elderly group (23%; lower right Figure). In paroxysmal AF (PAF), there was no difference in recurrence between Elderly and Non-Elderly, while Very Elderly remained associated with a significant increased risk (lower left Figure). Multivariate logistic regression comparing Elderly and Very Elderly to non-Elderly confirmed these findings (PersAF: Very Elderly: HR=1.44, p<0.0001, Elderly: HR=1.23, p=0.03; PAF: Very Elderly HR=1.29, p=0.017; Elderly: HR=1.04, p=0.62) (Table). Catheter ablation resulted in improvement in AFSS irrespective of age group at one year follow up (Non-Elderly:12→5., Elderly:11.5→4.5 and Very Elderly:11.5→5; p<0.001). At one year, AF duration was minimal in all groups but was the highest in the Very Elderly (7.4 vs 1.1 at 1 year) followed by Elderly (6.9 vs 0.7) and Non-Elderly (6.5 vs 0.6). Catheter ablation in Elderly and Very Elderly patients appears to be safe and efficacious. Very Elderly patients have a higher rate of AF recurrence when compared with Elderly or Non-Elderly. Nevertheless, ablation significantly improved AF burden and symptoms at one year in all age groups.Tabled 1Table - Logistic Regression Analysis Predicting AF Recurrence by Age Groups:GroupHR95% CIP valueMultivariable AnalysisAll PatientsNon-Elderly (<65 years)ReferenceElderly (≥65 <75)1.1461.03-1.270.009Very Elderly (≥75 years)1.3811.21-1.57<0.001ParoxysmalNon-Elderly (<65 years)ReferenceElderly (≥65 <75)1.040.89-1.210.62Very Elderly (≥75 years)1.2931.04-1.590.017Non-Elderly (<65 years)ReferenceElderly (≥65 <75)1.231.07-1.410.003Very Elderly (≥75 years)1.4431.22-1.70<.0001Models were adjusted for sex, age, prior ablation, prior cardioversion, prior use of antiarrhythmic drugs (AADs), prior AAD failure, use of Cryoballoon, posterior wall isolation.

Comparative Analysis on Clinical Characteristics Among Patients with Acute Hepatitis A Virus (HAV) and Patients with Acute Hepatitis E Virus (HEV): A Single-Center Retrospective Study from Bulgaria.

The acute viral hepatitis was one of the most common conditions in daily clinical practice varying in different parts of the world. The aim of the present study was to perform a comparative analysis on clinical characteristics among patients with acute hepatitis A virus (HAV) infection and patients with acute hepatitis E virus (HEV) infection admitted to the Military Medical Academy (MMA), Sofia, Bulgaria. A retrospective study was performed at MMA, between 1 January 2016 and 31 December 2021. The etiological diagnosis was confirmed by enzyme-linked immunosorbent assay (ELISA) HAV/HEV IgM serology assays. The current survey included 231 patients with mean age 45.11 ± 16.08 years (95% confidence interval: 43.04-47.19). According to the case definition, inclusion and exclusion criteria, persons were divided into two groups: patients with acute HAV infection (68.4%; 158/231) and patients with acute HEV infection (31.6%; 73/231). Males with HEV had 3.091 times the odds of comorbidity "hypertension" than males with HAV (p = 0.032). There were almost equal odds of increased ALT (odds ratio = 0.999; p = 0.003) in men with HEV and men with HAV. Females with HEV had 5.161 times the odds of comorbidity "hypertension" compared with females with HAV (p = 0.049). We found almost equal odds for elevated ALT in women with HEV and women with HAV (OR = 0.999; p = 0.025). In the non-elderly group (<60-year-old), HEV individuals had 4.544 and 10.560 times the odds of comorbidities "hypertension" and "cardiovascular diseases" compared with HAV patients (p < 0.05). We found almost equal odds for elevated ALT in HEV patients and HAV participants (OR = 0.998; p = 0.002). The results from the current study may support the physicians daily care for patients with acute HAV and acute HEV.

Promoting Appropriate Use of Medications by "Lectures and Practices Regarding Medicine" for the Regional Community Residents

We held lectures and practices for the regional community residents with the aim of promoting appropriate use of medications. To evaluate the usefulness of our activity, we conducted medicine-related questionnaire surveys (pre- and post-questionnaires) before and after the lectures and practices, and satisfaction with the activity questionnaire surveys (post-questionnaires) after them. We also evaluated the effect of age difference on the results by dividing the participants into elderly (age ≥65) and non-elderly (age <65), before the analysis. In the both (elderly and non-elderly) groups, the ratio of positive answers in several items of post-questionnaire regarding appropriate use of medications was higher than that of pre-questionnaire. These results suggest that the basic medicine-related knowledge improved by attending the lectures and practices, and indicate that the knowledge of the regional community residents is higher than we imagined. Furthermore, there was no difference in the ratio of positive answers between the both groups, suggesting that our activity is applicable to a wide range of age groups. Our activity benefitted the participants, and not only provided education to the regional community residents regarding appropriate drug use, but also lead to the development of regional community activity, by the coming together of the regional community residents of various age.

Efficacy and Safety of Electrohydraulic Lithotripsy Using Peroral Cholangioscopy under Endoscopic Retrograde Cholangiopancreatography Guidance in Older Adults: A Single-Center Retrospective Study.

Background and objectives: The safety of electrohydraulic lithotripsy (EHL) in older adults remains unclear. We aimed to investigate the efficacy and safety of EHL using peroral cholangioscopy (POCS) under endoscopic retrograde cholangiopancreatography (ERCP) guidance in older adults aged ≥80 years. Materials and Methods: This retrospective clinical study was conducted at a single center. Fifty patients with common bile duct stones who underwent EHL using POCS under ERCP guidance at our institution, between April 2017 and September 2022, were enrolled in this study. The eligible patients were divided into an elderly group (n = 21, age ≥80 years) and a non-elderly group (n = 29, age ≤79 years), and were analyzed. Results: A total of 33 and 40 EHL procedures were performed in the elderly and non-elderly groups, respectively. After excluding cases in which stone removal was performed at other institutions, complete removal of common bile duct stones was confirmed in 93.8% and 100% of the elderly and non-elderly groups, respectively (p = 0.20). The mean number of ERCPs required for complete removal of bile duct stones was 2.9 and 4.3 in the elderly and non-elderly groups, respectively (p = 0.17). In the EHL session, the overall occurrence of adverse events was eight and seven in the elderly (24.2%) and non-elderly (17.5%) groups, respectively; however, the difference was insignificant (p = 0.48). Conclusions: EHL using POCS under ERCP guidance is effective in patients aged ≥80 years and there was no significant increase in adverse event rates compared to those aged ≤79 years.

Discussion on the benefits of different treatment strategies in elderly and non-elderly patients with appendix MiNEN: a retrospective study based on SEER database.

To investigate the benefits of surgery alone and postoperative chemotherapy in elderly and non-elderly patients with appendiceal mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) and analyze the factors affecting the prognosis of patients with MiNEN of the appendix. Based on the Surveillance, Epidemiology, and End Results database (SEER) of the National Cancer Institute of the USA, 389 patients with appendiceal MiNENs from 2000 to 2016 were collected. All patients were distributed in the elderly group (≥ 60years old) and the non-elderly group (< 60years old) according to their age. The prognosis of the two groups of patients who received simple surgery and postoperative chemotherapy was analyzed and compared. The two treatment methods of the two tranches were matched by propensity score matching method. The effect of different treatment ways on the prognosis of sick persons was compared. The survivorship curves were painted by the Kaplan Meier method, log rank test was used to analyze the subsistence discrepancy of each group, and COX proportional risk model was used to analyze the factors affecting the prognosis of patients with appendiceal MiNENs. No matter the overall survival rate (OS) or cancer-specific mortality (CSM) of the two treatment schemes, the prognosis of patients in the only surgery group was meaningfully higher than that in the postoperative chemotherapy group, with statistically significant difference in component comparison (χ2 = 16.496, χ2 = 16.860, P < 0.001). After propensity score matching of patients in each group, there was no striking discrepancy in the OS of patients in the only surgery group compared with those in the postoperative chemotherapy group, regardless of whether they were elderly patients or non-elderly patients (χ2 = 3.205, χ2 = 1.521, all P > 0.05), the CSM consequences are fitting in with the OS. The consequences of the multivariate COX regression model showed that age (≥ 60years old), sex (female), high histological grade, and lymph node positive were all the influencing factors for the poor OS of patients with MiNEN; the CSM results are consistent with the OS. For patients with appendix MiNEN, whether elderly or non-elderly patients (especially for non-elderly patients), surgical treatment may be a better choice.

Characteristics and Clinical Outcomes of Elderly Patients with Trauma Treated in a Local Trauma Center

Purpose: This study aimed to investigate the characteristics of elderly patients who visited a non-regional trauma center to examine the effects of old age on the clinical outcomes of patients.Methods: The medical charts of 159 patients with trauma who visited the National Health Insurance Service Ilsan Hospital between March 2020 and February 2022 were retrospectively analyzed.Results: Of the 159 patients, 41 were assigned to the elderly patient group (EPG) and 118 were assigned to the non-elderly patient group (NEPG). The average age of patients in each group was 75.5 and 38.2 years in the EPG and the NEPG, respectively. Comparing the injury mechanism between the two groups, pedestrian traffic accidents (TA) were the most common (24.4%), followed by slipping (19.5%), motorcycle TA, and bicycle TA (14.6%) in EPG. In the NEPG, motorcycle TA (28.0%) was the most common, followed by car TA (27.1%), and fall injury (16.9%), with a significant difference between the two groups (&lt;i&gt;p&lt;/i&gt; &lt; 0.001). The significant differences between the two groups were the injury severity score (ISS; &lt;i&gt;p&lt;/i&gt; = 0.004), severe trauma (&lt;i&gt;p&lt;/i&gt; = 0.045), intensive care unit admission (&lt;i&gt;p&lt;/i&gt; = 0.028), emergency operation (&lt;i&gt;p&lt;/i&gt; = 0.034), and mortality (&lt;i&gt;p&lt;/i&gt; = 0.013). The statistically significant risk factors for mortality were old age (&lt;i&gt;p&lt;/i&gt; = 0.024) and chest injury (&lt;i&gt;p&lt;/i&gt; = 0.013).Conclusion: Patients in the EPG compared with the NEPG group showed different injury mechanisms. The EPG has a higher severity and mortality rate than the NEPG.

Clinical and survival outcomes of colectomy for transverse colon cancer in elderly patients.

It remains controversial whether elderly patients with transverse colon cancer present worse prognoses. Our study utilized evidence from multi-center databases to evaluate the perioperative and oncology outcomes of radical resection of colon cancer in elderly and nonelderly patients. In this study, we analyzed 416 patients with transverse colon cancer who underwent radical surgery from January 2004 to May 2017, including 151 elderly (aged ≥ 65 years) and 265 nonelderly (aged < 65 years) patients. We retrospectively compared the perioperative and oncological outcomes between these 2 groups. The median follow-up in the elderly and nonelderly groups was 52 and 64 months, respectively. There were no significant differences in the overall survival (OS) (P = .300) and disease-free survival (DFS) (P = .380) between the elderly and nonelderly groups. However, the elderly group had longer hospital stays (P < .001), a higher complication rate (P = .027), and fewer lymph nodes harvested (P = .002). The N classification and differentiation were significantly associated with OS based on univariate analysis, and the N classification was an independent prognostic factor for OS based on multivariate analysis (P < .05). Similarly, the N classification and differentiation were significantly correlated with the DFS based on univariate analysis. However, multivariate analysis indicated that the N classification was an independent prognostic factor for DFS (P < .05). In conclusion, the survival and surgical outcomes in elderly patients were similar to nonelderly patients. The N classification was an independent factor for OS and DFS. Even though elderly patients with transverse colon cancer present a higher surgical risk than nonelderly patients, performing radical resection in elderly patients can be an appropriate choice for treatment.

Comparison of the Relationship between Visual Acuity and Motor Function in Non-Elderly and Elderly Adults

This study aimed to clarify the relationship between visual acuity and motor function in younger and elderly participants and to compare differences between non-elderly and elderly participants. In total, 295 participants who underwent visual and motor functional examinations were included; participants with visual acuity ≥0.7 were assigned to the normal group (N group) and those with visual acuity ≤0.7 were assigned to the low-visual-acuity group (L group). Motor function was compared between the N and L groups; the analysis was performed by grouping participants into those aged >65 years (elderly) and those aged <65 years (non-elderly). The non-elderly group (average age, 55.6 ± 6.7 years) had 105 and 35 participants in the N and L groups, respectively. Back muscle strength was significantly lower in the L group than in the N group. The elderly group (average age, 71.1 ± 5.1 years) had 102 and 53 participants in the N and L groups, respectively. Gait speed was significantly lower in the L group than in the N group. These results reveal differences in the relationship between vision and motor function in non-elderly and elderly adults and indicate that poor vision is associated with lower back-muscle strength and walking speed in younger and elderly participants, respectively.

Age-Stratified Analysis of First-Line Chemoimmunotherapy for Extensive-Stage Small Cell Lung Cancer: Real-World Evidence from a Multicenter Retrospective Study.

Chemoimmunotherapy improved overall survival (OS) and progression-free survival (PFS) in patients with extensive-stage small cell lung cancer (ES-SCLC) in two phase III trials. They set the age-stratified subgroup analyses at 65 years; however, over half of the patients with lung cancer were newly diagnosed at ≥75 years in Japan. Therefore, treatment efficacy and safety in elderly patients ≥ 75 years with ES-SCLC should be evaluated through real-world Japanese evidence. Consecutive Japanese patients with untreated ES-SCLC or limited-stage SCLC unfit for chemoradiotherapy between 5 August 2019 and 28 February 2022 were evaluated. Patients treated with chemoimmunotherapy were divided into the non-elderly (<75 years) and elderly (≥75 years) groups, and efficacy, including PFS, OS, and post-progression survival (PPS) were evaluated. In total, 225 patients were treated with first-line therapy, and 155 received chemoimmunotherapy (98 non-elderly and 57 elderly patients). The median PFS and OS in non-elderly and elderly were 5.1 and 14.1 months and 5.5 and 12.0 months, respectively, without significant differences. Multivariate analyses revealed that age and dose reduction at the initiation of the first chemoimmunotherapy cycle were not correlated with PFS or OS. In addition, patients with an Eastern Cooperative Oncology Group performance status (ECOG-PS) = 0 who underwent second-line therapy had significantly longer PPS than those with ECOG-PS = 1 at second-line therapy initiation (p < 0.001). First-line chemoimmunotherapy had similar efficacy in elderly and non-elderly patients. Individual ECOG-PS maintenance during first-line chemoimmunotherapy is crucial for improving the PPS of patients proceeding to second-line therapy.

Ramelteon for delirium prevention in hospitalized patients: An updated meta-analysis and trial sequential analysis of randomized controlled trials.

Although ramelteon has been examined as a relatively new therapeutic option for delirium prevention, current evidence to evaluate its efficacy is limited. We conducted an updated meta-analysis and examine the reliability of existing evidence regarding the effect of ramelteon on delirium prevention in hospitalized patients. Seven major electronic databases were systematically searched to identify randomized controlled trials examining the efficacy of ramelteon in delirium prevention. Data were pooled using a frequentist-restricted maximum-likelihood random-effects model. A trial sequential analysis was performed using relative risk reduction thresholds of 50%. The primary outcome was the incidence of delirium (reported as odds ratio with 95% confidence intervals). The secondary outcomes were the days of delirium, all-cause mortality, and all-cause discontinuation. Of 187 potentially eligible studies identified, 8 placebo-controlled randomized controlled trials (n = 587) were included. This updated meta-analysis showed that ramelteon was associated with lower odds of delirium occurrence than placebo (0.50; 0.29-0.86; I2 = 17.48%). In trial sequential analysis, the effect of ramelteon across the superiority boundary when using a relative risk reduction threshold ranging from 40% to 60%. In subgroup analyses, ramelteon compared with placebo was associated with lower odds of delirium occurrence in the elderly group (k = 5; 0.28; 0.09-0.85; I2 = 27.93%) and multiple dosage group (k = 5; 0.34; 0.14-0.82; I2 = 44.24%) but not in the non-elderly and non-multiple dosage groups. When considering surgical patients and medical patients separately, ramelteon showed a trend in the treatment of delirium prevention in both groups, while these findings were not statistically significant. No significant between-group differences were found in the secondary outcomes. The current meta-analysis provides updated and reliable evidence that ramelteon, in comparison with placebo, reduces the risk of delirium among hospitalized patients.

Outcomes of endoscopic resection for early gastric cancer in very elderly patients: A nationwide population-based study.

403 Background: Few studies have investigated the long-term outcomes of endoscopic resection for early gastric cancer (EGC) in very elderly patients. The aim of this study was to determine the appropriate treatment strategy and identify the risk factors for mortality in these patients. Methods: Patients with EGC who underwent endoscopic resection from 2006 to 2017 were identified using National Health Insurance Data and divided into three age groups: very elderly (≥85 years), elderly (65–84 years), and non-elderly (≤64 years). Their long- and short-term outcomes were compared in the three age groups, and the survival in the groups was compared with that in the control group, matched by age and gender. We also evaluated the risk factors for long- and short-term outcomes. Results: A total of 8,426 patients were included in our study: 118 very elderly, 4,583 elderly, and 3,725 non-elderly. The overall survival (OS) and cancer-specific survival (CSS) rates were significantly lower in the very elderly group than in the elderly and the non-elderly groups. Congestive heart failure was negatively associated with CSS. A significantly decreased risk for mortality was observed in all groups (P-value &lt; 0.001). The very elderly group had significantly higher readmission and mortality rates within 3 months of endoscopic resection than the non-elderly and elderly groups. Further, cerebrovascular disease was associated with mortality within 3 months after endoscopic resection. Conclusions: Endoscopic resection for EGC can be helpful for very elderly patients, and it may play a role in achieving OS comparable to that of the control group.[Table: see text]

Efficacy and tolerability of immune checkpoint inhibitors in elderly patients with MSI/dMMR gastrointestinal cancers and impact of toxicities on efficacy: The immunoMSI cohort.

795 Background: Immune checkpoint inhibitors (ICI) are the new standard of care for some MSI/dMMR advanced tumors in first-line setting or after progression under conventional chemotherapy. Frequency of MSI/dMMR increasing with age, the tolerability and efficacy of ICIs in elderly patients, appears as a crucial clinical issue. We aimed to evaluate the tolerability and efficacy of ICIs in ≥ 75 years patients with metastatic MSI/dMMR gastro-intestinal (GI) cancer. Methods: All pts with MSI/dMMR metastatic GI cancer treated by anti-PD1 ± anti-CTLA4 without concomitant chemotherapy at Saint-Antoine hospital and included in our prospective, monocenter cohort, were analyzed. Pts were divided into the elderly (≥75 years) and non-elderly (&lt;75 years) groups. The incidence and evolution of grade ≥ 3 immune-related adverse events (irAE) and grade ≥ 2 endocrine adverse events were evaluated. Secondary objectives were progression-free survival (PFS) and overall survival (OS) regarding age and the occurrence of irAEs. Results: Two hundred and one patients were included: 24 pts≥75 years (75 to 90 years) and 177 pts&lt; 75 years (22 to 74 years). 171 (79%) had mCRC. In the entire population, the incidence of irAEs was 40.5% with anti-PD1 plus anti-CTLA4 and 23% with anti-PD1 monotherapy (p= 0.011). Combination of anti-PD1 and anti-CTLA4 were administered to 29% of the elderly group and 40% of the non-elderly group. There was no statistical difference in the incidence of irAEs between the two populations (37.5% in the elderly group vs 29% in the non-elderly group; p=0.48) neither in their type (12% vs 7% of hepatic cytolysis, 13% vs 16% of endocrine irAEs) or management (17% vs 19% corticosteroid therapy, 21% and 16% of ICI discontinuation). No significant difference was observed between elderly/non elderly for PFS (HR 0.91, 95%CI 0.40-2.06; p=0.83) and OS (HR 1.6, 95%CI 0.65-3.96; p= 0.21). Pts experiencing irAEs had superior survival outcomes than those without irAEs (PFS HR 2.93, 95%CI 1.69-5.09; p=0.02 and OS HR 2.05, 95%CI 1.13-3.74; p=0.045) in the whole cohort (n=201). Conclusions: Tolerability and efficacy of ICIs for pts with MSI/dMMR GI cancers are similar for elderly compare as for non-elderly pts. Pts experiencing irAEs had superior survival outcomes. Further prospective studies with systematic geriatric assessment are required to evaluate the tolerability of ICIs especially for frail elderly pts.

Prognostic Significance of Preoperative Nutritional Assessment in Elderly Patients who Underwent Laparoscopic Gastrectomy for Stage I-III Gastric Cancer.

Surgery for elderly patients with gastric cancer is becoming more common. However, the risk factors of the laparoscopic surgery for these patients are unknown, and thus it is difficult to determine appropriate treatments for such patients. The aim of this retrospective study was to clarify the risk factors for the treatment outcomes after laparoscopic gastrectomy in elderly patients. Two hundred twenty-two patients who underwent laparoscopic gastrectomy for primary gastric cancer between January 2014 and December 2017 were enrolled. Clinical characteristics and short- and long-term prognoses were analyzed in 47 patients aged 75 years or older (elderly group) and in 175 patients who were under 75 years old (non-elderly group). The presence of comorbidities was more common in the elderly group than in the non-elderly group (91.5% vs. 61.7%, p<0.0001). The rate of postoperative complications in the elderly group was significantly higher than that in the non-elderly group (42.6% vs. 22.9%, p=0.01). The 5-year overall survival rate was significantly lower in the elderly group than in the non-elderly group (66.9% vs. 92.2%; p<0.0001). In the elderly group, 5-year overall survival in patients with a low preoperative prognostic nutritional index (PNI) was significantly worse than that in patients with a high preoperative PNI (25.0% vs. 80.9%; p<0.05). Multivariate analysis showed that the PNI value was independently associated with overall survival in elderly patients who underwent laparoscopic gastrectomy (p<0.05). In particular, the rate of non-cancer deaths after surgery in elderly patients was significantly higher than that in non-elderly patients (p<0.05). PNI value is an independent prognostic factor for overall survival in elderly patients who have undergone laparoscopic gastrectomy for gastric cancer; therefore, in elderly patients with low preoperative PNI, attention should be paid not only to recurrence of cancer, but also to the deterioration of general condition caused by malnutrition.

Outcomes of elderly patients following thoracoscopic esophagectomy for esophageal cancer.

Thoracoscopic esophagectomy (TE) is widely used for esophageal cancer treatment. However, the short- and long-term outcomes of TE in older patients remain unknown. Thus, we investigated those outcomes as well as the effectivity of TE in this patient cohort. A total of 228 consecutive patients who underwent TE for esophageal cancer from 2002 to 2015 were included in the study and categorized into the elderly (≥ 75years) and non-elderly (< 75years) groups. The background was adjusted by propensity score matching. The short- and long-term outcomes were then compared between the two groups. There was no difference in the short-term outcomes between the two groups. The elderly group had significantly lower overall survival (OS) and relapse-free survival (RFS) than the non-elderly group. When pulmonary complications occurred, the OS and RFS were significantly decreased in the elderly group but not in the non-elderly group. Without pulmonary complications, the OS and RFS in the elderly group did not differ from those in the non-elderly group. The multivariate analysis showed that pulmonary complications were independent poor prognostic factors for OS and RFS in the elderly group but not in the non-elderly group. TE is safe and feasible for older patients. However, the OS and RFS of the elderly group were significantly worse than those of the non-elderly group, especially when pulmonary complications occurred. Therefore, perioperative management to prevent pulmonary complications is essential to improve the long-term outcomes of older patients receiving TE.

A study on the factors influencing old age identity among the Chinese elderly.

Old age identity is the self-perception of when old age begins, reflects public age values and acceptance of aging. Not all elderly people aged 60 and above identify with their old age status. The aging society in the traditional sense may not be "aging". Therefore, redefining old age is crucial. Different from Western countries, China is a country with a long-standing culture of respect for the elderly and filial piety norms, and the influence of the cultural background on the old age identity is worthy of attention. Data were drawn from the 2014 China Longitudinal Aging Social Survey (CLASS). A total of 7400 participants answered questions about old age identity. Based on old age identity, we obtained two other types of indicators of perceived old age: elderly group identity and aging degree. For the continuous variable old age identity and aging degree, an OLS linear regression model was established. A binary logistic regression model was established for the binary variable elderly group identity. The average old age identity of Chinese people aged 60 and above is 70 years. Health status, psychological status, behavior, socioeconomic status, and some demographic characteristics significantly affect the old age identity of the Chinese elderly. The traditional Chinese cultural background of respect for the elderly and the norms of filial piety have an impact on the old age identity of the Chinese elderly through family intergenerational support. The various forms of support provided by children to the elderly can help them achieve a positive age identity-enter old age later, raise the likelihood of identification with non-elderly groups, and reduce aging degree. The number of children of the elderly, the children's economic conditions and care support for grandchildren have negative effects. A positive old age identity can help the elderly improve their self-esteem.

Characteristics of Postoperative Patients with Breast Cancer Aged 65 Years and Older.

Objective: This study aimed to compare postoperative patients with breast cancer aged ≥65 years with those aged <65 years and clarify the characteristics of postoperative patients with breast cancer aged ≥65. Methods: In total, 376 patients in whom we were able to evaluate survey items one month after surgery were included in the study. Comorbidity, including diabetes mellitus and hypertension, shoulder range of motion (ROM), upper-limb function, and psychological problems, was evaluated. Results: Hypertension and diabetes mellitus were significantly higher in patients aged ≥65 years (the elderly group) than in those aged <65 years (the non-elderly group) (p < 0.05). Preoperative shoulder flexion ROM was significantly restricted in the elderly group compared with the non-elderly group (p < 0.05). Preoperative shoulder abduction ROM was significantly restricted in the elderly group compared with the non-elderly group (p < 0.05). At one month after surgery, upper-limb function was more impaired in the non-elderly group than in the elderly group (p < 0.05). In both groups, both ROM and upper-limb function were significantly impaired one month after surgery compared with before surgery (p < 0.05). Conclusions: Postoperative patients with breast cancer aged ≥65 years should be careful about risk management and intervention during rehabilitation. Preoperative evaluation of shoulder ROM should be performed because patients aged ≥65 years have limited ROM before surgery.

AngioJet rheolytic thrombectomy for the treatment of deep vein thrombosis in elderly patients: Increase the risk of acute kidney injury?

The objective of this study was to investigate the risk of acute kidney injury in elderly patients compared with nonelderly patients undergoing AngioJet rheolytic thrombectomy for treatment of acute deep vein thrombosis. A retrospective review of all patients who underwent AngioJet rheolytic thrombectomy for the treatment of acute deep vein thrombosis between November 1, 2014 and August 1, 2022 was conducted. Their baseline demographics, comorbidities, clinical characteristics, procedural details, and postoperative course were reviewed. A total of 105 eligible patients were reviewed; 45 patients were in the elderly group, and 60 were in the nonelderly group. Except for age (p < 0.001), no significant differences regarding demographics were detected (p >0.05). Transient macroscopic hemoglobinuria occurred in all patients during the first 24 h post-AngioJet rheolytic thrombectomy. The overall morbidity of acute kidney injury in the two groups was 11.4%, and the nonelderly group had a similar rate of acute kidney injury (8.3%) to the elderly group (15.6%). None of the 12 patients progressed to dialysis within the postoperative period, and the mean acute kidney injury recovery time of the elderly group was 5.86 ± 1.57 days, which was longer than the 3.60 ± .89 days of the nonelderly group (p = 0.017). The use of AngioJet rheolytic thrombectomy for the treatment of patients with acute deep vein thrombosis is associated with a potential risk of acute kidney injury, which seems to have a comparable rate in elderly and nonelderly patients. acute kidney injury in the elderly group tends to need a longer recovery time, which requires postoperative vigilance for this population.

What are the mortality markers in elderly patients with acute pulmonary embolism?

This study investigates characteristics and predictors of mortality among elderly patients with acute pulmonary embolism (APE). Data on patients with the diagnosis of APE at the first admission to two centers between January 2012 and March 2022 were screened retrospectively. Patients aged 65 years and older were categorized as the elderly group while patients between 18 and 64 years of age constituted the non-elderly group. Among the 361 enrolled patients, the average age in the non-elderly group was 51.0 (18.0-64.0) years and the average age in the elderly group was 76 (65.0-92) years. While male patients were the majority in the non-elderly group, there was a higher proportion of female patients in the elderly group (p=0.001). In multivariate regression analysis, the independent risk factors of mortality among elderly patients were oxygen saturation [odds ratio (OR): 1.163, 95% confidence interval (CI): 1.613-9.476; p=0.044], C-reactive protein (CRP) (OR: 1.133, 95% CI: 1.041-1.234; p=0.004), simplified Pulmonary Embolism Severity Index (sPESI) score (OR: 3.910, 95% CI: 1.613-9.476; p=0.003), absence of deep vein thrombosis (OR: 12.88, 95% CI: 1.321-125.739; p=0.028), and leukocyte count (OR: 2.591, 95% CI: 1.015-6.617; p=0.047). In ROC analysis, the cut-off values for mortality prediction were ≥7.7 mg/dL for CRP, >0.125 ng/mL for troponin, and ≥2 for the sPESI score. If CRP of ≥7.7, troponin of >0.125, and sPESI score of ≥2 are present in elderly patients with APE, extra attention should be paid to the risk of mortality and the utmost care should be taken in planning the monitoring of these patients.

Clinical Characteristics and Outcomes of Patients with Intracerebral Hemorrhage: Nonsurgical Versus Surgical Treatment.

Primary intracerebral hemorrhage (ICH) is a stroke subtype with high morbidity and mortality. Surgical treatments for ICH may be one of the beneficial modalities. There are inconsistent clinical outcomes of surgical treatments in several randomized controlled trials. This study aimed to evaluate if surgical treatment can reduce mortality in patients with ICH in a real-world setting. This was a retrospective analytical study. The inclusion criteria were consecutive adult patients aged 18 years or over admitted to neurosurgery ward due to ICH, and indicated for surgical treatment according to the 2015 guideline for the management of spontaneous ICH. The outcomes of this study included mortality, length of stay, Barthel index, Glasgow Outcome Score (GOS), and Glasgow Coma Scale (GCS). Descriptive statistics were used to execute the differences between those who underwent and did not undergo surgical treatments. Factors associated with mortality were computed by multivariate logistic regression analysis. There were 110 patients with ICH who met the study criteria. Of those, 34 (30.91%) patients underwent surgical treatment: mainly craniotomy (16 patients; 47.06%). The surgical treatment group had significantly higher proportions of large ICH of 30 mL or over (62.96% vs. 27.54%; P = 0.002) and intraventricular hemorrhage (70.59% vs. 46.05%; P = 0.023) than the nonsurgical treatment group. However, both groups had comparable outcomes in terms of mortality, length of stay, Barthel index, GOS, and GCS. The mortality rate in the surgery group was 47.06%, whereas the nonsurgery group had a mortality rate of 39.47 (P = 0.532). There were three independent factors associated with mortality, including age, GCS, and intraventricular hemorrhage. The adjusted odds ratio (95% confidence interval) of these factors was 1.06 (1.02-1.12), 5.42 (1.48-19.81), and 5.30 (1.65-17.01). Intraventricular hemorrhage was more common in the elderly than in the nonelderly group (66.00% vs. 43.33%; P = 0.022). Surgical treatment may not be beneficial in patients with severe ICH, particularly with intraventricular hemorrhage, large ICH volume, or low GCS. Elderly patients with ICH may also have high mortality if intraventricular hemorrhage is present.

The relationship between vitamin B12, folate and homocysteine levels in the elderly Turkish population

Aging is associated with increased incidence and prevalence of chronic diseases, and the role of micronutrient deficiencies in the development of diseases is important. Vitamin B12 and folic acid deficiency are often associated with increased homocysteine (Hcy) levels. In our study, we aimed to detect the relationship between Hcy levels by examining vitamin B12 and folate levels in the healthy elderly Turkish population. In our study, the levels of vitamin B12, folate, and Hcy were analyzed and examined in 657 elderly and 642 non-elderly healthy adults admitted to the Internal medicine outpatient clinic. Vitamin B12 &lt;200 pg/mL was considered to be deficient. Folic acid &lt;5 ng/mL was considered a deficiency, and Hcy&gt;15 µmol/L was considered a high concentration. Vitamin B12 levels were detected to be significantly decreased in the elderly group compared to the non-elderly group, while Hcy levels were marked to be increased (p&lt;0.05). Women had lower levels of Hcy and higher levels of vitamin B12 and folate (p&lt;0.05). There was a moderate negative correlation between Hcy and vitamin B12 levels in the elderly group (r=-0.576; p&lt;0.0001), and a moderate negative correlation between Hcy and folate (r=-0.510; p&lt;0.0001). In the elderly group, 21.5% had vitamin B12 deficiency and 21.6% had folate deficiency. An increase in Hcy level was detected in 54.8%. Those with Hcy levels &gt;15 µmol/L had vitamin B12 deficiency in 38.4%, folate deficiency in 36.0%, and both vitamin B12 and folate deficiency in 15.8%. Our results indicate that it is important to measure vitamin B12, folate, and Hcy in the elderly, given the significant growth in the elderly population. We predict that vitamin B12 and folate supplementation, when necessary, may be beneficial in preventing some common diseases in the elderly and increasing the standard of life of the elderly and their relatives.
