109 Hyponatraemia in Older Patients is Often Untreated, Despite Greater Mortality Burden; Results of A Prospective Cohort Study

Abstract Introduction Hyponatraemia is associated with increased morbidity and mortality, and is commoner in elderly patients. The aetiology and outcomes of hyponatraemia in the elderly has not been defined in prospective studies. Methods A single-centre 9 month prospective observational study of hyponatraemic (HN) patients (</= 130 mmol/L) was performed. Clinical outcomes in patients ≥65 years (Elderly patients, EP) and those <65 years (Young Patients, YP) were analysed, and compared with age-matched eunatremic controls, Analysis was performed using Graphpad-Prism 7. Results 1321 consecutive admissions with hyponatraemia (67% EP, median age of EP 77 (65–98) years) and 1122 eunatremic controls (63% EP, median age of EP 77 (65–99) years) were analysed. Median nadir plasma sodium was similar in both groups with HN, 128 (107–130) mmol/L EP vs 128(110–130) mmol/L YP (p = 0.62). EP hyponatraemic patients were more likely to have hypovolaemic hyponatraemia (34%) compared with YP with hyponatraemia (28%, p = 0.03). Diuretic-induced hyponatraemia was twice as common in EP (8%) compared with YP (4%, p = 0.01). Malignancy-induced SIAD occurred with similar frequency in both groups (7% in EP SIAD vs 8% in YP SIAD, p = 0.65). Respiratory disease was causative in 10% cases of EP SIAD, compared with 4% in YP SIAD, p = 0.0004. Hyponatraemia was corrected in 53% of EP, compared with 64% of YP, p = 0.0001. Length of stay and re-admissions rates were similar across hyponatraemia age groups. EP with HN were 2.4 times more likely to die in hospital, compared with eunatremic age-matched controls, (OR 2.4, 95% CI 1.6–3.7, p < 0.0001). Conclusions The causation of hyponatraemia is different in elderly patients. Hyponatraemia in EP is often uncorrected, despite increased mortality compared with eunatremic age-matched controls.

Common Cause

Introduction: In the elderly, impairment of kidney function occurs. Renal diseases overlap with anatomic and functional changes related to age-related involutionary processes. Mortality among patients with acute renal injury is approximately 50%, despite advances in treatment and diagnosis of AKI. The aim: To assess the incidence of acute kidney injury in elderly patients and to analyze the causes of acute renal failure depending on age. Materials and methods: A retrospective analysis included medical documentation of patients hospitalized in the Nephrology Clinic during the 6-month period. During this period 452 patients were hospitalized in the clinic. A group of 77 patients with acute renal failure as a reason for hospitalization was included in the study. Results: The prerenal form was the most common cause of AKI in both age groups. In both age groups, the most common cause was dehydration; in the group of patients up to 65 years of age, dehydration was 29.17%; in the group of people over 65 years - 43.39%. Renal replacement therapy in patients with AKI was used in 14.29% of patients. In the group of patients up to 65 years of age hemodialysis was 16.67% and above 65 years of age. -13.21% of patients. The average creatinine level in the group of younger patients at admission was 5.16 ± 3.71 mg / dl, in the group of older patients 3.14 ± 1.63 mg / dl. The size of glomerular filtration GFR in the group of younger patients at admission was 21.14 ± 19.54 ml / min, in the group of older patients 23.34 ± 13.33 ml / min. Conclusions: The main cause of acute kidney injury regardless of the age group was dehydration. Due to the high percentage of AKI in the elderly, this group requires more preventive action, not only in the hospital but also at home.

PURPOSE: The surgical treatment of colorectal cancer (CRC) in elderly patients (age 70 years or older) has improved, but data on adjuvant and palliative chemotherapy tolerability and benefits in this growing population remain scarce. Elderly patients are underrepresented in clinical trials, and results for older patients are seldom reported separately. PATIENTS AND METHODS: Using a prospective database, we analyzed demographics, chemotherapy toxicity, response rates, failure-free survival (FFS), and overall survival (OS) of CRC patients receiving chemotherapy at the Royal Marsden Hospital. The cutoff age was 70 years. RESULTS: A total of 844 patients received first-line chemotherapy with various fluorouracil (5-FU)-containing regimens or raltitrexed for advanced disease, and 543 patients were administered adjuvant, protracted venous infusion 5-FU or bolus 5-FU/folinic acid (FA) chemotherapy. Of the 1,387 patients, 310 were 70 years or older. There was no difference in overall or severe (Common Toxicity Criteria III to IV) toxicity between the two age groups, with the exception of more frequent severe mucositis in older patients receiving adjuvant bolus 5-FU/FA. For patients receiving palliative chemotherapy, no difference in response rates (24% v 29%, P = .19) and median FFS (164 v 168 days) were detected when the elderly were compared with younger patients. Median OS was 292 days for the elderly group and 350 days for the younger patients (P = .04), and 1-year survival was 44% and 48%, respectively. The length of inpatient hospital stay was identical. CONCLUSION: Elderly patients with good performance status tolerated adjuvant and palliative chemotherapy for CRC as well as did younger patients and had similar benefits from palliative chemotherapy.

7553 Background: Adjuvant cisplatin-based chemotherapy (CT) has been shown to increase survival in NSCLC, but uncertainty exists concerning its efficacy and toxicity in elderly patients (≥ 70). Methods: We performed a pooled analysis using individual patient data from 4,584 patients in the LACE database with resected stage IA-III NSCLC enrolled in 5 randomized trials, comparing postoperative CT to no CT (ALPI, ANITA, BLT, IALT and JBR10). Patient and treatment characteristics, CT toxicity and delivery, overall survival, disease-free survival (DFS) and cause-specific mortality were compared among 3 age groups: 3,269 (71%) young (<65), 901 (20%) mid-category (65–69) and 414 (9%) elderly (≥70). The analysis was performed on an intent-to-treat basis. Cox models stratified by trials and adjusted for age, associated drug, planned radiotherapy, total dose of cisplatin (<300, 300, >300), gender, stage, performance status, type of surgery and histology were used with a test for trend to study the effect of CT on survival according to age. Results: Baseline characteristics differed among the age groups, but this was due mainly to the different trial populations and designs. No difference in severe toxicity rate was observed among the age groups. Elderly patients received significantly smaller total doses of cisplatin than the other patients (Chi2-test: p<0.0001) and also the cisplatin doses received were more often lower than the planned one (Kruskal-Wallis test: p<0.0001). The Hazard ratio (HR) of death for the young patients was 0.82 (95% CI 0.73–0.92), 0.86 (95% CI 0.70–1.07) for the mid category and 1.01 (95% CI 0.78–1.32) for elderly patients (test for trend: p=0.17). The HR for DFS was 0.79 (95% CI 0.71–0.87) for the young, 0.76 (95% 0.62–0.93) for the mid category and 0.94 (95% CI 0.73–1.22) for the elderly patients (test for trend: p=0.35). More elderly patients died from non- lung cancer related causes (10% young, 16% mid category and 20% elderly; p<0.0001). Conclusions: The survival benefit from cisplatin-based adjuvant therapy for NSCLC patients was not significantly different according to age, but this may be due to lack of power.

Before 1980 few patients over the age of 65 started chronic dialysis, despite the fact that the incidence of advanced chronic renal failure was approximately ten times greater in this group compared to young and middle aged adults.1 Since that time the number of elderly patients starting renal replacement has increased markedly and accounted for 38% of new dialysis patients in Scotland in 1995. (Data supplied by the Scottish Renal Registry). In order to meet the needs of older patients with chronic renal failure there has been considerable expansion in renal services and it has been predicted that this will continue to increase in Scotland until 2010.2 The number of older patients receiving dialysis and transplantation is rising steadily and will continue to rise in the future. There is nowadays no justification for a rigid upper age limit in the selection of patients for dialysis although inevitably more elderly patients will be unsuitable on medical grounds than in the younger age groups in particular due to cardiovascular disease. The majority of elderly patients are best managed by haemodialysis but a considerable number can achieve a reasonable quality of health on peritoneal dialysis. Renal transplantation should be seriously considered in the older patient provided that comorbidity is not present, usually in the form of cardiovascular disease, to a degree which would seriously limit life expectation.

Abstract Introduction Hyponatraemia is associated with increased morbidity and mortality; the aetiology and outcomes of hyponatraemia in older patients have not been defined in prospective studies. Methods A single-centre 9-month prospective observational study in which clinical outcomes in hospitalised patients ≥ 65 years (older patients with hyponatraemia (OP-HN)) and those <65 years (young patients with hyponatraemia (YP-HN)) with hyponatraemia were analysed, and compared with eunatraemic controls (older patients with normonatraemia (OP-NN) and young patients with normonatraemia (YP-NN)). Results In total, 1,321 episodes of hyponatraemia in 1,086 patients were included; 437 YP-HN, median age 54 years (IQR 44,60) and 884 OP-HN, median age 77 years (IQR 71,82). A total of 1,120 consecutive eunatraemic control patients were simultaneously recruited; 690 OP-NN, median age 77 years (IQR 71,83) and 430 YP-NN, median age 52 years (IQR 41,58). Euvolaemic hyponatraemia was the commonest cause of hyponatraemia in both age groups (48% in YP-HN and 46% in OP-HN). Sixty-two percent of OP-HN received hyponatraemia-directed treatment within the initial 48 h, compared with 55% of YP-HN, P = 0.01. Despite the greater treatment rates in OP-HN, younger patients were 24% more likely to be discharged with normal plasma sodium concentration (pNa) compared with older patients, relative risk (RR) 1.24 (95% confidence interval (CI) 1.12–1.37), P < 0.001. Using OP-NN as the reference group, the RR of in-hospital death in OP-HN was 2.15 (95% CI 1.3–3.56), P = 0.002. Using YP-NN as the reference group, the RR of in-hospital death in YP-HN was 4.34 (95% CI 1.98–9.56), P < 0.001. Conclusion Despite greater rates of HN-targeted treatment, the risk of in-hospital death is increased in older hyponatraemic patients compared with older eunatraemic controls. The impact of hyponatraemia on mortality is even greater in younger patients.

33 Background: Gastric cancer is one of the most common cancers, having great incidence among the elderly. However, little is known about gastric cancer in elderly patients. This study was designed to evaluate the specific features of gastric cancer in elderly patients. Methods: We reviewed medical records of 1107 patients who had undergone radical gastrectomy for gastric cancer between June 2005 and December 2009 retrospectively. They were divided into young age group (<65, n = 676), middle age group (65 ≤ age < 75, n = 332) and old age group (≥75, n = 99). To find out potential risk factors, these following factors were reviewed; symptoms, comorbidities, tumor marker levels, stages, H. pylori status, locations, Lauren type, differentiation, complications, microsatellite instability and p53 overexpression. Results: Elevated levels of CA 19-9 (5.6%, 13.4% and 14.6%, P = 0.001), advanced diseases (42.5%, 47.0% and 57.6, P = 0.014), and node metastasis (37.6%, 38.9% and 51.5%, P = 0.029) were more frequently detected in the middle and old age groups. However, no significant differences in H. pylori status (63.6%, 56.7% and 61.2%, P = 0.324) were observed among the three groups. Elderly patients had a tendency to show intestinal type in Lauren’s classification (40.7%, 58.7%, and 56.6%, P < 0.001). The rate of surgery-related complications did not differ among the three groups (5.3%, 5.1%, and 8.1%, P = 0.497). Microsatellite instability (P < 0.001) and p53 overexpression (P < 0.001) were more frequently found among the elderly patients. Conclusions: Gastric cancer in elderly patients was related to features known for favorable prognosis except p53 overexpression, despite the more advanced stage. Surgery in the elderly was as tolerable as in young patients. We recommend looking favorably upon surgery for elderly patients with operable gastric cancers.

New Model

BACKGROUND Healthcare for older patients is a worldwide challenge for public health system. A new medical Internet system in healthcare which is a new model of telegeriatrics system has been established. The key innovation is the new telegeriatrics system was conducted jointly by general practitioners in the Community Health Service Center and specialists in university teaching hospital. Unlike the typical telemedicine that has been practiced in other countries, the new model provides a solution for the key issues in telemedicine where a doctor is unable to conduct a direct physical examination and the associated potential diagnostic error. OBJECTIVE This study is to introduce the operation mechanism of the new Telegeriatrics system and analyze healthcare demands of older patients in different age groups applying the new Telegeriatrics system. METHODS 472 older patients (aged≥60) were enrolled and divided into the young older group (aged 60 to 74), the old older group (aged 75 to 89) and the very old group (aged≥90) according to the age stratification of World Health Organization. Proportion of the top 10 diseases of older patients of different age groups was analyzed. RESULTS The process of older patients’ diagnosis and treatment made by specialist and general practitioners formed a closed loop. It ensures the timeliness and effectiveness of diagnosis and treatment of older patients. The treatment effect can be observed by general practitioners and specialist can adjust the treatment plan in time. In this study, it was found that older patients in different age groups have different healthcare demands. Coronary heart disease and type 2 diabetes mellitus were found to be the main diseases of the older patients and the young older patients as well as the old older patients applying Telegeriatrics. CONCLUSIONS The new telegeriatrics system can provide convenient and efficient healthcare services for older patients and overcome the disadvantage of currently used models of telegeriatrics. Older patients in different age groups have different medical care demands. Cardiovascular diseases and metabolic diseases have become the main diseases of the elderly applying the new Telegeriatrics system. Healthcare policy makers should invest more medical resources to the prevention of cardiovascular diseases and metabolic diseases in the elderly.

End Point

Introduction: In patients with atrial fibrillation (AF) at risk for stroke, dabigatran 150 mg twice a day (DE150) is superior to warfarin for stroke prevention. However, there is paucity of data with respect to bleeding risk at this dose in elderly patients (≥75 years). We aimed to evaluate the safety of DE150 in comparison to warfarin in a real-world population with AF and low bleeding risk (HAS-BLED score ≤2). Methods: In this prospective observational study, 754 consecutive patients with AF and HAS-BLED score ≤2 were included. We compared outcome of elderly patients (age ≥75 tears) to younger patients (age <75 years). The primary end point was the combined incidence of all-cause mortality, stroke, systemic emboli, and major bleeding event during a mean follow-up of 1 year. Results: There were 230 (30%) elderly patients, 151 patients were treated with warfarin, and 79 were treated with DE150. Fifty-two patients experienced the primary endpoint during the 1-year follow-up. Among the elderly, at 1-year of follow-up, the cumulative event rate of the combined endpoint in the DE150 and warfarin was 8.9 and 15.9% respectively (p = 0.14). After adjustment for age and gender, patients who were treated with DE150 had a nonsignificant difference in the risk for the combined end point as patients treated with warfarin both among the elderly and among the younger population (HR 0.58, 95% C.I = 0.25–1.39 and HR = 1.12, 95% C.I 0.62–2.00, respectively [p for age-group-by-treatment interaction = 0.83). Conclusions: Our results suggest that Dabigatran 150 mg twice a day can be safely used among elderly AF patients with low bleeding risk.

AbstractBackground:Cochlear implantation is the standard of care for treating severe to profound hearing loss in all age groups. There is limited data on long-term results in elderly implantees and the effect of ageing on outcomes. This study compared the stability of cochlear implantation outcome in elderly and younger patients.Methods:A retrospective chart review of cochlear implant patients with a minimum follow up of five years was conducted.Results:The study included 87 patients with a mean follow up of 6.8 years. Of these, 22 patients were older than 70 years at the time of implantation. Hearing in Noise Test scores at one year after implantation were worse in the elderly: 85.3 (aged under 61 years), 80.5 (61–70 years) and 73.6 (aged over 70 years;p= 0.039). The respective scores at the last follow up were 84.8, 85.1 and 76.5 (p= 0.054). Most patients had a stable outcome during follow up. Of the elderly patients, 13.6 per cent improved and none had a reduction in score of more than 20 per cent. Similar to younger patients, elderly patients had improved Short Form 36 Health Survey scores during follow up.Conclusion:Cochlear implantation improves both audiometric outcome and quality of life in elderly patients. These benefits are stable over time.

OBJECTIVE To review and evaluate the medical literature concerning antiepileptic drug (AED) therapy in elderly patients. DATA SOURCES A MEDLINE search (1982–December 2004) was conducted. Bibliographies of the articles identified were also reviewed, and an Internet search engine was used to identify additional pertinent references. STUDY SELECTION AND DATA EXTRACTION Clinical studies and reviews were evaluated, and relevant information was included. DATA SYNTHESIS The elderly have the highest incidence of seizures among all age groups. Complex partial seizures are the most common, followed by primary generalized tonic–clonic seizures. An accurate diagnosis may prove difficult because of a low suspicion of epilepsy in the elderly and other diseases that may mimic seizures. Most AEDs are approved for treatment of elderly patients who have partial and tonic–clonic seizures. However, a number of age-related variables should be addressed when selecting an appropriate AED. Age-dependent differences in pharmacokinetics and pharmacodynamics of AEDs must be taken into account. Drug–drug interactions must be considered since elderly people often take multiple medications. The ultimate factor that often determines AED selection is tolerability. CONCLUSIONS Numerous factors must be considered in treating elderly patients for seizures, but maximizing the ability of patients to tolerate drug therapy is often the basis for AED selection. Special consideration should be made along several lines, including elderly patients’ cognitive functioning and their tendency to respond to lower AED concentrations.
