Background & Aims: In view of the global demographic shift, a scientific symposium was organised by the European Society for Clinical Nutrition and Metabolism (ESPEN) to address nutrition-related challenges of the older population and provide an overview of the current state of knowledge., Methods: Eighteen nutrition-related issues of the ageing global society were presented by international experts during the symposium and summarised in this report., Results: Anorexia of ageing, dysphagia, malnutrition, frailty, sarcopenia, sarcopenic obesity, and the metabolic syndrome were highlighted as major nutrition-related geriatric syndromes. Great progress has been made in recent years through standardised definitions of some but not all syndromes. Regarding malnutrition, the GLIM approach has shown to be suitable also in older adults, justifying its continuous implementation. For anorexia of ageing, a consensus definition is still required. Intervention approaches should be integrated and person-centered with the aim of optimizing intrinsic capacity and maintaining functional capacity. Landmark studies like EFFORT and FINGER have impressively documented the potential of individualised and multifactorial interventions for functional and health benefits. Combining nutritional intervention with physical training seems particularly important whereas restrictive diets and drug treatment should generally be used with caution because of undesirable risks. Obesity management in older adults should take into account the risk of promoting sarcopenia., Conclusions: In the future, even more individualised approaches like precision nutrition may enable better nutritional care. Meanwhile all stakeholders should focus on a better implementation of currently available strategies and work closely together to improve nutritional care for older adults., Competing Interests: Conflict of interest All authors have declared their individual conflicts of interest according to the rules of the International Committee of Medical Journal Editors (ICMJE). None of the expert panel had to be excluded from the symposium faculty or from coauthorship because of serious conflicts. The conflict of interest forms are stored at the ESPEN office and can be reviewed with legitimate interest upon request to the ESPEN executive., (Copyright © 2024 The Author(s).

Objective: Potentially inappropriate medications (PIM) is a crucial problem in the geriatric population. The amount of prescription and unadherence increase because of the different problems encountered in cancer patients. Our aim was to evaluate the effects of PIM in patients with gastrointestinal system cancer and to investigate its relationship with chemotherapy side effects, mortality, and progression., Methods: This retrospective cohort study assessed 154 patients with gastrointestinal system cancer. Demographics and disease features, the presence of PIM according to the "TIME-to-STOP" criteria and baseline laboratory parameters were recorded. The effects of PIM on survival and adverse treatment events were evaluated., Results: 66.9% of the cases were male and 33.1% were female. The mean age was 71.9±6.4 years. The most common side effects of chemotherapy are nausea, vomiting, kidney injury, and pain. The most frequently used prescriptions among the 98 PIMs were gliclazide, hyoscine N-butylbromide, simethicone, diphenoxylate atropine, and thiocolchicoside. PIM was detected in 68.1% of the participants. Chemotherapy side effects were more common in PIM group (p<0.001, odds ratio =5.6). PIM had no effect on mortality. Factors associated with mortality were age, stage, albumin, creatinine, operation history, and progression. A significant relationship was found between age, cancer stage, albumin, creatinine, operation history, and PIM in the regression model. There was no relationship between PIM and progression-free survival., Conclusion: Chemotherapy toxicity may increase with PIM detected on diagnosis. We suggest that PIM is an important factor in predicting the side effects of chemotherapy and minimizing the adverse effects., Competing Interests: Conflict of Interest: The authors have no conflict of interest to declare., (Copyright© 2023 The Author.

Background & Aim : Muscle strength seems to be more relevant to the functionality than muscle mass in sarcopenia. Different diagnostic techniques are available for the evaluation of muscle mass. Ultrasonography (USG) seems to have some advantages compared to other techniques especially bioelectrical impedance analysis (BIA) including being not affected of the results by the factors like extreme body mass indexes (BMI) or hypervolemia. The aim of the study is to determine and compare the muscle strength prediction value of muscle mass measured by using USG or BIA and determine the cut-off values for the Turkish population. Methods : One hundred and thirty six patients admitted to geriatrics outpatient clinic for comprehensive geriatric assessment were included in the study. Body composition was determined by BIA and skeletal muscle mass ındex (SMI) was measured. Thickness of the gastrocnemius muscle was measured via USG. Diagnosis of sarcopenia was made according to the EWSGOP 2 diagnostic criteria. Results : The best cut-off value for gastrocnemius muscle thickness to predict low HGS was ≤13.8 mm (AUC:0.690,p <0.001). SMI was not found to predict low HGS (AUC:0.573,p >0.05). Comparison of AUCs for gastrocnemius muscle thickness and SMI showed that gastrocnemius muscle thickness had higher AUC (p=0.008). For predicting sarcopenia, the best cut-off value of gastrocnemius muscle thickness was found to be ≤12.3 mm in women (AUC: 0.862,p <0.001) and ≤12.3 mm in men (AUC:0.900, p < 0.001). Conclusions : In this study, we found that gastrocnemius thickness measured by USG seems to predict low HGS better than SMI measured by BIA.

Background: Insomnia increases the incidence of falls and impairs executive function. Moreover, falls are associated with executive function impairment. The relationship between falls and executive function in patients with insomnia is not clear. The aim of this study was to evaluate relationship between falls and executive function in individuals with insomnia and a control group., Methods: This study involved 122 patients (47 insomnia, 75 controls). The Mini-Mental State Examination, Quick Mild Cognitive Impairment Screen, Trail Making Test A, clock-drawing test, and digit span test were used to measure executive function. Semantic and working memory dual task was also performed. Fall history was recorded and the Falls Efficacy Scale - International administered., Results: The median age of the patients was 71 years (range: 65-89 years), and 60.7% were women. The insomnia group scored lower on the three-word recall than the control group (P = 0.005), but there was no difference between the groups on cognitive tests. Fall history and fear of falling were more frequent in the insomnia group (P = 0.003, P < 0.001). Semantic and working memory dual tasks were correlated with clock-drawing test only in the insomnia group (r = -0.316, P = 0.031; r = -0.319, P = 0.029). Depression (odds ratio (OR) = 9.65, P = 0.001) and Trail Making Test A (OR = 1.025, P = 0.07) were independently associated with insomnia. Four-metre walking speed (OR = 2.342, P = 0.025), insomnia (OR = 3.453; P = 0.028), and the semantic memory dual task (OR = 1.589; P = 0.025) were also independently associated with falls., Conclusion: Our study showed that dual tasking and executive function are related to falls in patients with insomnia. Managing insomnia and assessment of executive dysfunction may have beneficial effects on preventing falls., (© 2021 Japanese Psychogeriatric Society.)

Background: Sarcopenic obesity (SO) is the coexistence of sarcopenia and obesity in an individual. The present study is designed to define the usefulness of skeletal muscle ultrasonography (US) in the definition of SO., Methods: Eighty-nine participants aged ≥65 whose body mass index (BMI, kg/m 2 ) was ≥30 were consecutively enrolled in an outpatient clinic of geriatric medicine. All underwent comprehensive geriatric assessment. US measurements were obtained in 6 different muscles consisting of core and limb muscles. We defined SO as the presence of low muscle function (defined by a handgrip strength < 27 kg in males and <16 kg in females) and high BMI (≥30)., Results: The median age of the participants was 72 (65-85) years; 81% were female, and 35% (n = 31) had SO. Anthropometric parameters that estimate muscle mass were lower in the sarcopenic group, but estimations of muscle mass with bioelectrical impedance analysis (BIA) did not differ between groups. All US estimations of muscle mass were lower in sarcopenic obese participants, albeit not all significantly. RF muscle cross-sectional area (RF CSA) and abdominal subcutaneous fat thickness were most strongly correlated with grip strength (r = 0.477 and r = -508, respectively). Receiver operating characteristic analysis suggested that the optimum cutoff point of RF CSA for SO was ≤5.22 cm 2 , with 95.8% sensitivity and 46.7% specificity (area under the curve: 0.686)., Conclusions: US evaluation of muscle mass may be more accurate than BIA-derived skeletal muscle index assessment for the diagnosis of SO., (© 2020 American Society for Parenteral and Enteral Nutrition.)

Introduction: There are various 'quality of life' scales developed for older people. Although quality of life is a subjective concept, most of these scales are based on expert opinions rather than perspectives of older people. The aim of this study is to evaluate validity and reliability of Older People's Quality of Life-brief scale (OPQOL-brief), which is based on perspectives of older people, in Turkish population., Methods: A cross-sectional study was implemented in a Geriatric medicine outpatient clinic. Total number of 168 older patients who speak in Turkish fluently were recruited. Comprehensive geriatric assessment and OPQOL-brief was applied to all participants together with another quality of life scale validated in Turkish population, CASP-19 (Control, Autonomy, Self-realization, Pleasure). Validity was evaluated with construct validity, convergent validity and discriminant validity. Reliability was assessed with internal consistency and test-retest reliability., Results: Mean age of the study population was 73.3 ± 5.9 years. Female participants were 64.9% (n = 109). Internal consistency was assessed by Cronbach's α coefficient. OPQOL-brief scale demonstrated high internal consistency (Cronbach's α = 0.876). Test-retest reliability was assessed by interclass correlation coefficient (ICC) and showed high reliability (ICC = 0.98, 95%CI = 0.96-0.99, p < 0.001). Strong and significant correlation was detected between OPQOL-brief and CASP-19 scales (r = 0.763, p < 0.001)., Conclusion: Turkish version of OPQOL-brief has acceptable validity and reliability in Turkish population. The scale can be used to measure quality of life of older people., (Copyright © 2019 Elsevier B.V. All rights reserved.)

We aimed to investigate the expressions of p27 kinase inhibitory protein 1 (p27 Kip1 ) and calcium sensing receptor (CaSR) in adenomas and normal parathyroid tissue and to evaluate the relationship of these molecules with clinical and biochemical parameters in primary hyperparathyroidism (PHPT). Fifty-one patients with histopathologically confirmed parathyroid adenomas and 20 patients with normal parathyroid glands (which were removed incidentally during thyroid resection) were included. Immunohistochemical stainings of CaSR and p27 Kip1 were performed in surgical specimens. Clinical features, biochemical parameters, and BMD measurements of patients with PHPT were evaluated retrospectively. Expressions of p27 Kip1 and CaSR were decreased in parathyroid adenomas, compared to normal glands (p < 0.05). High intensity of CaSR staining (3+) was more frequent in normal parathyroid tissue (75%) than adenomas (12%) (p < 0.01). Hypertension was not observed in patients with high staining intensity of CaSR (p = 0.032). There was a negative association between CaSR expression and body mass index (BMI) (p = 0.027, r = - 0.313). There was no significant relationship between p27 Kip1 and CaSR expressions, serum calcium, plasma parathormone, 25-hydroxy vitamin D levels, and bone density (p > 0.05). The expressions of p27 Kip1 and CaSR were decreased in PHPT patients. This reduction may play an important role in the pathogenesis of PHPT. However, neither p27 Kip1 nor CaSR expression was found to be useful in predicting prognosis or severity of disease.
