Abstract Background Colorectal cancer (CRC) is one of the most common cancers in the world. The number of elderly patients with CRC increases due to aging of the population. There are few studies that examined chemotherapy and prognostic factors in metastatic colorectal cancer (mCRC) patients aged ≥ 80 years. We assessed the efficacy of chemotherapy and prognostic factors among patients with mCRC aged ≥ 80 years. Methods We retrospectively analyzed clinical and laboratory findings of 987 patients newly diagnosed with CRC at Asahi General Hospital (Chiba, Japan) between January 2012 and December 2016. The Kaplan–Meier method was used for the overall survival (OS) and the log-rank test was used to identify difference between patients. A multivariate Cox proportional hazard regression analysis was performed to determine the hazard ratios and 95% confidence intervals (CIs) of prognostic factors among super-elderly patients. Results In total, 260 patients were diagnosed with mCRC (super-elderly group: n = 43, aged ≥ 80 years and younger group, n = 217, aged < 80 years). The performance status and nutritional status were worse in the super-elderly group than in the younger group. The OS of super-elderly patients who received chemotherapy was worse than that of younger patients (18.5 vs. 28.8 months; P = 0.052), although the difference was not significant. The OS of patients who received chemotherapy tended to be longer than that of those who did not; however, there were no significant differences in OS in the super-elderly group (18.5 vs. 8.4 months P = 0.33). Multivariate analysis revealed that carcinoembryonic antigen levels ≥ 5 ng/mL (hazard ratio: 2.27; 95% CI 1.09–4.74; P = 0.03) and prognostic nutritional index ≤ 35 (hazard ratio: 8.57; 95% CI 2.63–27.9; P = 0.0003) were independently associated with poor OS in the super-elderly group. Conclusions Patients with mCRC aged ≥ 80 years had lower OS than younger patients even though they received chemotherapy. Carcinoembryonic antigen and prognostic nutritional index were independent prognostic factors in super-elderly patients with mCRC, but chemotherapy was not. Trial registration: retrospectively registered.

Objectives: Aging is a major risk factor for many neurological disorders and is associated with dural lymphatic dysfunction. We sought to evaluate the association of aging with the volume of the peri-sinus lymphatic space using contrast-enhanced 3T T1-weighted black-blood magnetic resonance imaging (MRI). Methods: In this retrospective study, 165 presumed neurologically normal subjects underwent brain MRIs for cancer staging between April and November 2018. The parasagittal peri-sinus lymphatic space was evaluated using contrast-enhanced 3D T1-weighted black-blood MRIs, and volumes were measured with semiautomatic method. We compared the volumes of normalized peri-sinus lymphatic spaces between the elderly (≥65 years, n = 72) and non-elderly (n = 93) groups and performed multivariate logistic regression analyses to assess if aging is independently associated with the volume of normalized peri-sinus lymphatic spaces. Results: The normalized peri-sinus lymphatic space volume was significantly higher in the elderly than in the non-elderly (mean, 3323 ± 758.7 mL vs. 2968.7 ± 764.3 mL, p = 0.047). After adjusting the intracranial volume, age age was the strongest factor independently associated with peri-sinus lymphatic space volume (β coefficient, 28.4 (5.7–51.2), p = 0.015) followed by male sex (β coefficient, 672.4 (113.5–1230.8), p = 0.019). Conclusions: We found that the peri-sinus dural lymphatic space volume was higher in the elderly group than in the non-elderly group, and the increased peri-sinus lymphatic space was independently associated with aging. These findings indicate that the peri-sinus lymphatic space may be related with the aging process and lymphatic system dysfunction as well.

Background:Recently, vital prognosis has been improved in patients with rheumatoid arthritis (RA)1. In elderly patients, it is difficult to establish a treatment strategy due to multi-morbidities and treatment-related risks. Since older age is a significant risk factor of serious infections, one of the primary concerns during treatment of RA, rheumatologists should always strike a balance between efficacy and safety of the immunosuppressive treatment. However, infection data under the targeted therapy (TT) in elderly patients is still limited to date.Objectives:To compare the risk of hospitalized infection (HI) under the TT among young, elderly, and older elderly patients with RA using the Japanese health insurance database.Methods:This retrospective longitudinal population-based study was conducted using claims data in Japan provided by Medical Data Vision Co., Ltd. We defined individuals as RA cases if they met all of the following: 1) having at least one ICD10 code (M05x, M06x except for M061, or M08x except for M081 and M082); 2) having at least one prescription of disease-modifying antirheumatic drugs (DMARDs) including methotrexate (MTX) and TT (biological DMARDs and Janus kinase inhibitors) between April 2008 and September 2018; and 3) 16 years old or older. We define the month patients met the above all criteria for the first time in this database as the index month. We excluded patients who were prescribed any DMARDs during the first 12 months from MTX users and those with prescription of any TT during the first 12 months from TT users (i.e., prevalent users). Among the study population, we divided patients into 3 groups according to their age at the index month; young group (16-64), elderly group (65-74), and older elderly group (>=75). The observation started from the index month and ended at 36 months later, the last month of the exposure of DMARDs, the month of loss of follow-up, or September 2019, whichever came first. HI was defined by ICD10 code with one prescription of predefined drugs for each infection during hospitalizations. Some of HIs were defined by ICD10 code alone.Results:In this study, 8269, 6454, 5745 patients with RA were included in the young, elderly, and older elderly groups, respectively. The incidence rate (IR) of HI (/100 patient-years [PY]) [95%CI] was 3.4 [3.1-3.7] in the young group, 5.8 [5.3-6.3] in the elderly group, and 12.0 [11.2-12.8] in the older elderly group. IR rate (IRR) of HI (reference: the young group) was 1.7 [1.5-1.9] in the elderly group and 3.6 [3.2-4.0] in the older elderly group. In the young group, the IRR of HI in TT users vs MTX users was significantly elevated (1.8 [1.5-2.1]), whereas, those of the elderly and the older elderly groups were significantly decreased (IRR 0.8 [0.7-0.9] for elderly; 0.6 [0.5-0.7] for older elderly). Concomitant use of immunosuppressive DMARDs or prednisolone >=10mg/day with TT became less frequent with aging.Conclusion:The elderly and older elderly patients had significantly higher risks of HI compared to the young. The risk of HI under the TT compared to MTX was decreased in the elderly patients, probably due to adjusting for treatment by attending physicians.References:[1]Arthritis Rheum 2014;66:786-93Acknowledgments:This work was supported by JSPS KAKENHI Grant Number 17K08963.Disclosure of Interests:Ryoko Sakai Grant/research support from: Tokyo Women’s Medical University (TWMU) has received unrestricted research grants forDivision of Epidemiology and Pharmacoepidemiology of Rheumatic Diseases from Ayumi Pharmaceutical Co.

Radical cystectomy is the most common treatment for deeply invasive bladder cancer; due to reported operative risks, concerns have been expressed regarding the suitability of this operation in elderly patients. We reviewed the morbility and mortality rates in 50 patients aged 70 years and over (elderly group), undergoing radical cystectomy and urinary diversion, to verify if this procedure could be considered as initial treatment in older-age patients. The findings were compared with those observed in 50 patients aged 40 to 69 years (control group). In the elderly group there was no operative mortality; however 2 patients (4%) died post-operatively due to pulmonary embolism and multi-organ-failure syndrome respectively. Four patients (8%) were re-operated due to intestinal obstruction (2 pts), pelvic hematoma (1 pt) and wound dehiscence (1 pt). Wound separation was the more frequent complication (15%); 6% of patients experienced extended intestinal atonia. The length of hospital stay was 17.1 days. In the control group, surgical complications were comparable to those observed in the elderly group: furthermore medical complications were more frequent. In conclusion, these data suggest that radical cystectomy and urinary diversion can be safely performed in the elderly. Radical surgery is an effective treatment modality for elderly individuals who are in reasonably good general health. A higher incidence of medical complications must be expected in elderly patients.

The effect of the multi-exercise program on cognitive function in overweight and non-overweight elderlyBackground: Cognitive function is the factor that determines the disability of the elderly to live a healthy and independent life. The results of studies regarding the protective effect or detrimental effects of overweight or obesity on cognitive function in the elderly are still controversial. Objective: This study aims to determine the effect of the multi-exercise program on cognitive function in the elderly based on nutritional status.Methods: This quasi-experimental study with a pretest-postest design study involved 37 elderly aged 60-74 years. Body mass index (BMI) derived from the measurement of body weight and height were grouped into overweight and not-overweight. Both groups received a multi-exercise in the form of gymnastic exercise (30 minutes), square stepping exercise (30 minutes), and puzzle games (30 minutes). The intervention was given 12 times with a frequency of 3 times per week. Cognitive function was measured by using the Mini-Mental State Examination (MMSE) questionnaire. Data analysis used paired sample t-test and independent t-test. Results: The multi-exercise program intervention given affected improving cognitive function in the overweight elderly group (p=0.003). However, it is different from the non-overweight elderly group who did not show a significant effect of the multi-exercise program on the cognitive function (p=0.184) even though there was an increase in the mean cognitive function at the end of the intervention. Conclusions: Multi-exercise program intervention for 4 weeks with a frequency of three times per week can improve the cognitive function of the elderly, but statistically only significant in the overweight elderly group.

Background: Left bundle branch pacing (LBBP) has been shown to be a safe and effective means to achieve physiological pacing. However, elderly patients have increased risks from invasive procedures and the risk of LBBP in elderly patients is not known. We aimed to investigate the safety and efficacy of LBBP in elderly patients &gt;80 years of age.Methods: From December 2017 to June 2019, 346 consecutive patients with symptomatic bradycardia, 184 patients under 80 years of age and 162 over 80 years, were included and underwent LBBP. The safety and prognosis of LBBP were comparatively evaluated by measured pacing parameters, periprocedural complications, and follow-up clinical events.Results: Compared with the younger, the elderly group had worse baseline cardiac and renal function. LBBP was achieved successfully in both groups with comparable fluoroscopic time and paced QRS duration (110.0 [102.0, 118.0] ms for the young vs. 110.0 [100.0, 120.0] ms for the elderly, P = 0.874). Through a follow-up of 20.0 ± 6.1 months, pacing parameters were stable while higher threshold and impedance were observed in the elderly group. In the evaluation of safety, overall procedure-related complication rates were comparable (4.4 vs. 3.8%, young vs. elderly). For prognosis, similar rates of major adverse cardiocerebrovascular events (7.1 vs. 11.9%, young vs. elderly) were observed.Conclusions: Compared to younger patients, LBBP could achieve physiological pacing in patients over 80 with comparable midterm safety and prognosis. Long-term safety and benefits of LBBP, however, necessitate further evaluation.
