Opioids in geriatric units in 14 Belgian hospitals: prevalence, dosage and associated factors.

Introduction: Adverse effects of opioids are common among older individuals, and undertreatment as well as overuse can be an issue. Epidemiological data on opioid use in older individuals are available, but scarce in hospitalized patients.Aims: The aim of this study is to examine the one-day prevalence of opioid use among older inpatients and identify the factors associated with both opioid use and dosage.Materials and methods: One-day cross-sectional study with data collected from geriatric units across 14 Belgian hospitals. The primary focus of the study is to assess the prevalence of opioid use and dosage, along with identifying associated factors. To achieve this, a multiple binary logistic regression model was fitted for opioid use, and a multiple linear regression model for opioid dose.Results: Opioids were used in 24.4% of 784 patients, of which 57.9% was treated with tramadol, 13.2% with oxycodone or morphine and 28.9% with transdermal buprenorphine or fentanyl. The odds for opioid use were 4.2 times higher in patients in orthogeriatric units compared to other patients (OR=4.2, 95% CI=2.50-7.05). The prevalence of opioid use was 34% higher in patients without dementia compared to patients with dementia (OR=0.66, 95% CI=0.46-0.95). The overall mean daily dosage was 14.07mg subcutaneous morphine equivalent. After adjustment for age, gender and dementia, dosage was only associated with type of opioid: the estimated mean opioid dose was 70% lower with tramadol (mean ratio=0,30,95% CI=0,23-0,39) and 67% lower with oxycodone and morphine (mean ratio=0,33, 95% CI=0,22-0,48) compared to transdermal buprenorphine and transdermal fentanyl.Conclusions: One in four patients received opioid treatment. It is not clear whether this reflects under- or overtreatment, but these results can serve as a benchmark for geriatric units to guide future pain management practices. The utilization of transdermal fentanyl and buprenorphine, resulting in higher doses of morphine equivalent, poses significant risks for side effects.

Functional decline in older patients with cancer receiving chemotherapy: A multicenter prospective study.

OBJECTIVES: This study aims to evaluate the evolution of functional status (FS) 2 to 3months after initiation of chemotherapy, to identify factors associated with functional decline during chemotherapy treatment and to investigate the prognostic value of functional decline for overall survival (OS). PATIENTS AND METHODS: Patients ≥70years with a malignant tumor were included when chemotherapy was initiated. All patients underwent a geriatric assessment (GA) including FS measured by Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL). FS of patients was followed by repeating ADL and IADL to identify functional decline. RESULTS: From 10/2009 until 07/2011, 439 patients were included. At follow-up, ADL and IADL data were available for 387 patients. Functional decline in ADL and IADL was observed in 19.9% and 41.3% of the patients respectively. In multivariable logistic regression analysis, baseline factors associated with decline in ADL are abnormal nutritional status (OR:2.02) and IADL dependency (OR:1.76). Oncological setting (disease progression/relapse vs new diagnosis) (OR:0.59) is the only determinant of decline in IADL. Functional decline in ADL is strongly prognostic for OS (logrank p-value<.0001; Wilcoxon p-value<.0001) with HR 2.34 and functional decline in IADL is also prognostic for OS but less prominent with HR 1.25. CONCLUSIONS: Functional decline occurs in about a third of older patients with cancer receiving chemotherapy and is associated with GA components. It strongly predicts survival, the most prominent for ADL. This knowledge can be used to identify older persons with cancer receiving chemotherapy eligible for interventions to prevent functional decline.

Relevance of Geriatric Assessment in Older Patients With Colorectal Cancer.

INTRODUCTION: This study aims to evaluate the relevance of geriatric assessment (GA) in older patients with colorectal cancer (CRC) and to study functional status (FS) and chemotherapy-related toxicity during treatment. METHODS: Patients with CRC aged ≥ 70 years were evaluated at baseline using a GA. Results were communicated to the treating physician. At 2 to 3 months follow-up, FS was reassessed, and chemotherapy-related toxicity was recorded. RESULTS: A total of 193 patients, with a median age of 77 years, were included. GA was abnormal in 75% and revealed unknown problems in 40%. Treatment was altered in 37% based on clinical assessment. GA led to geriatric interventions in 9 patients (5%) and additionally influenced treatment in 1 patient. At follow-up (n = 164), functional decline was observed in 29 patients (18%) for activities of daily living (ADL) and in 60 patients (37%) for instrumental activities of daily living (IADL). Baseline IADL, depression, fatigue, and cognition were predictors for ADL decline, whereas no predictors for IADL decline could be identified. In the 109 patients receiving chemotherapy, stage and baseline fatigue were predictive for grade 3/4 hematologic toxicity, and baseline ADL, fatigue, and nutrition were predictive for grade 3/4 nonhematologic toxicity. CONCLUSION: Although GA identified previously unknown problems in more than one-third of older CRC patients, the impact on interventions or treatment decisions was limited. Baseline GA parameters may predict functional decline and chemotherapy-related toxicity. Education of physicians treating older patients with CRC is an essential step in the implementation of GA and subsequent interventions.

Fall predictors in older cancer patients: a multicenter prospective study.

BACKGROUND: In the older population falls are a common problem and a major cause of morbidity, mortality and functional decline. The etiology is often multifactorial making the identification of fall predictors essential for preventive measures. Despite this knowledge, data on falls within the older cancer population are limited. The objective of this study was to evaluate the occurrence of falls within 2 to 3 months after cancer treatment decision and to identify predictors of falls (≥1 fall) during follow-up. METHODS: Older patients (70 years or more) with a cancer treatment decision were included. At baseline, all patients underwent geriatric screening (G8 and Flemish Triage Risk Screening Tool), followed by a geriatric assessment including living situation, activities of daily living (ADL), instrumental activities of daily living (IADL), fall history in the past 12 months, fatigue, cognition, depression, nutrition, comorbidities and polypharmacy. Questionnaires were used to collect follow-up (2-3 months) data. Univariate and multivariate analyses were performed to identify predictors for falls (≥1 fall) during follow-up. RESULTS: At baseline, 295 (31.5%) of 937 included patients reported at least one fall in the past 12 months with 88 patients (29.5%) sustaining a major injury. During follow-up (2-3 months), 142 (17.6%) patients fell, of whom 51.4% fell recurrently and 17.6% reported a major injury. Baseline fall history in the past 12 months (OR = 3.926), fatigue (OR = 0.380), ADL dependency (OR = 0.492), geriatric risk profile by G8 (OR = 0.471) and living alone (OR = 1.631) were independent predictors of falls (≥1 fall) within 2-3 months after cancer treatment decision. CONCLUSION: Falls are a serious problem among older cancer patients. Geriatric screening and assessment data can identify patients at risk for a fall. A patient with risk factors associated with falls should undergo further evaluation and intervention to prevent potentially injurious fall incidents.

Effect of advanced glycation end product intake on inflammation and aging: a systematic review.

Aging is associated with a chronic low-grade inflammatory status that contributes to chronic diseases such as age-related muscle wasting, kidney disease, and diabetes mellitus. Since advanced glycation end products (AGEs) are known to be proinflammatory, this systematic review examined the relation between the dietary intake of AGEs and inflammatory processes. The PubMed and Web of Science databases were screened systematically. Seventeen relevant studies in humans or animals were included. The intervention studies in humans showed mainly a decrease in inflammation in subjects on a low-AGE diet, while an increase in inflammation in subjects on a high-AGE diet was less apparent. About half of the observational studies found a relationship between inflammatory processes and AGEs in food. When the results are considered together, the dietary intake of AGEs appears to be related to inflammatory status and the level of circulating AGEs. Moreover, limiting AGE intake may lead to a decrease in inflammation and chronic diseases related to inflammatory status. Most of the trials were conducted in patients with chronic kidney disease or diabetes, and thus additional studies in healthy individuals are needed. Further investigation is needed to elucidate the effects of lifetime exposure of dietary AGEs on aging and health.

Performance of two geriatric screening tools in older patients with cancer.

PURPOSE: To compare the diagnostic characteristics of two geriatric screening tools (G8 and Flemish version of the Triage Risk Screening Tool [fTRST]) to identify patients with a geriatric risk profile and to evaluate their prognostic value for functional decline and overall survival (OS). PATIENTS AND METHODS: Patients ≥ 70 years old with a malignant tumor were included if a new cancer event occurred requiring treatment decision. Geriatric screening with G8 and fTRST (cutoff ≥ 1 [fTRST (1)] and ≥ 2 [fTRST (2)] evaluated) was performed in all patients, as well as a geriatric assessment (GA) evaluating social situation, functionality (activities of daily living [ADL] + instrumental activities of daily living [IADL]), cognition, depression, and nutrition. Functionality was re-evaluated 2 to 3 months after cancer treatment decision, and death rate was followed. Functional decline and OS were evaluated in relation to normal versus abnormal score on both screening tools. RESULTS: Nine hundred thirty-seven patients were included (October 2009 to July 2011). G8 and fTRST (1) showed high sensitivity (86.5% to 91.3%) and moderate negative predictive value (61.3% to 63.4%) to detect patients with a geriatric risk profile. G8 and fTRST (1) were strongly prognostic for functional decline on ADL and IADL, and G8, fTRST (1), and fTRST (2) were prognostic for OS (all P < .001). G8 had the strongest prognostic value for OS (hazard ratio for G8 normal v abnormal, 0.38; 95% CI, 0.27 to 0.52). CONCLUSION: Both geriatric screening tools, G8 and fTRST, are simple and useful instruments in older patients with cancer for identifying patients with a geriatric risk profile and have a strong prognostic value for functional decline and OS.

The influence of clinical assessment (including age) and geriatric assessment on treatment decisions in older patients with cancer.

OBJECTIVES: The aim of this prospective study in older patients with cancer was to evaluate how clinical assessment (including age) determines the physician's treatment decisions, and how geriatric assessment (GA) further influences these decisions. PATIENTS AND METHODS: Patients aged ≥70years old with cancer were included if a new therapy was considered. All patients underwent a GA and results were communicated to the treating physician. After the final treatment decision, a predefined questionnaire was completed by the physician. RESULTS: In total, 937 patients with median age of 76years old were included. A total of 902 (96.3%) questionnaires were completed by the treating physicians. In 381/902 patients (42.2%) clinical assessment led to a different treatment decision compared to younger patients without co-morbidities. This difference was most prominent for chemotherapy/targeted therapy decisions. In 505/902 cases (56%) the treating physician consulted GA results before the final treatment decision. In these patients, the treatment decision was influenced by clinical assessment in 44.2%. In 31/505 patients (6.1%) the GA further influenced treatment, mostly concerning chemotherapy/targeted therapy. In eight patients GA influenced the physician to choose a more aggressive chemotherapy. CONCLUSIONS: Physicians use different treatment regimens in older versus younger patients, based on clinical assessment, including age. GA results further influence treatment decisions in a minority of patients and may trigger the use of less aggressive as well as more aggressive treatments. GA information is not always utilized by oncologists, indicating the need for better education and sensitization.

Circulating heat shock protein 70 in health, aging and disease.

BACKGROUND: Heat shock proteins (Hsp) are ubiquitously synthesised in virtually all species and it is hypothesised that they might have beneficial health effects. Recent studies have identified circulating Hsp as an important mediator in inflammation - the effects of low-grade inflammation in the aging process are overwhelming. While much is known about intracellular Hsp70, scant data exist on circulating Hsp70 in the aging context. Therefore, the objectives of this study were to investigate the effect of age and disease on circulating Hsp70 and, in particular, to evaluate the association between circulating Hsp70 and inflammatory parameters. RESULTS: Serum Hsp70, Interleukin (IL) -10, IL-6 and Tumor Necrosis Factor (TNF) alpha concentrations were determined in 90 hospitalised geriatric patients (aged 83 ± 6 years) and in 200 community-dwelling control subjects (100 elderly, aged 74 ± 5 years, and 100 young, aged 23 ± 3 years). In the community-dwelling elderly, serum Hsp70 and IL-10 concentrations were significantly lower and IL-6 was significantly higher when compared to healthy young control subjects. Elderly patients presenting inflammation (CRP serum levels ≥5 mg/L) showed significantly (p = 0.007) higher Hsp70 values; and Hsp70 correlated positively (p < 0.001) with IL-6 and CRP, but not with TNF-alpha or IL-10. A significant association was also noted between Hsp70 levels and the degree of dependency and cognitive decline in geriatric patients. CONCLUSIONS: The present data provide new evidence that serum concentration of Hsp70 decreases with age in a normal population. Our study also shows that higher levels of Hsp70 are associated with inflammation and frailty in elderly patients.

Galantamine (Reminyl) once daily outcome and satisfaction survey (RODOS) in mild to moderate Alzheimer's disease: a study in a real life population.

AIM: To record in real life the appreciation of elderly patients, their caregivers and physicians of a once daily formulation of prolonged release of galantamine in the treatment of mild to moderate Alzheimer's disease. METHODS: A prospective, multicenter, observational study was conducted in 128 elderly patients, treated for 6 months with galantamine, donepezil or rivastigmine. RESULTS: Of the patients treated with galantamine, 82 of the 97 (84.5%) were continuing their treatment after 6 months. These patients reported their condition as improved in 49%, unchanged in 47% and worsened in 4%. Caregivers rated global evaluation as 37% better, 41% unchanged and 22% worse. Physicians rated global clinical impression of change as 46% better, 34% unchanged and 20% worse. Measurements of cognition and behavior remained stable. The appreciation of physicians and caregivers corresponded well (P<0.001). The incidence of serious side-effects possibly related to galantamine was 9.3%, which was not different from that in patients treated with other cholinesterase inhibitors. CONCLUSION: In a real life setting, galantamine once daily is safe and is favorably appreciated by patients, their caregivers and physicians.

Sarcopenia and functional decline: pathophysiology, prevention and therapy.

Twenty years ago, the term 'sarcopenia' has been introduced to describe the ageing related loss of skeletal muscle mass. Since then, sarcopenia has been intensively studied and prevalence values have been reported in fifteen papers covering several continents and races. However, consistency regarding the outcome measures and corresponding cut-off values defining sarcopenia is lacking. Most approaches are based on estimations of muscle mass and proposed cut-off values might be too strict, thus reducing their use in daily practice. From a clinical viewpoint, the assessment of muscle performance (grip strength and endurance) can be proposed as a screening tool showing sufficient sensitivity. The pathophysiology of sarcopenia is multifactorial, and important changes at the tissue level have been identified. Close relationships with inflammatory processes have been demonstrated and there is strong evidence for the involvement of a chronic low-grade inflammatory activity. Sarcopenia is aggravated by a complex interaction of several factors among which aging, disuse, immobilization, disease and malnutrition. A comprehensive geriatric assessment should allow the clinician to estimate the relative contribution of these factors and to elaborate appropriate management. From all interventions studied, intensive resistance training seems the most efficient to counter sarcopenia, even in the very old geriatric patients. Significant ameliorations (up to >50% strength gain) can be expected after six weeks of training at a rhythm of 2-3 sessions per week. From a preventive viewpoint, all elderly patients should be advised to start such an exercise program and continue it as long as possible. To date, most pharmacological interventions to counter sarcopenia include drugs with anabolic effects. Unfortunately, their effect is questionable and no clear guidelines exist for the prescription of these products in the context of sarcopenia.
