Effects of Potentially Inappropriate Medications in Older Patients with Gastrointestinal System Cancer.

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.

The impact of vitamin D deficiency on clinical, biochemical and metabolic parameters in primary hyperparathyroidism.

BACKGROUND: It has been suggested that vitamin D deficiency is associated with worse clinical outcomes in primary hyperparathyroidism (PHPT). We aimed to evaluate the relationship between vitamin D deficiency and clinical, biochemical and metabolic parameters in PHPT patients. METHODS: A total of 128 patients with biochemically confirmed PHPT were included. Patients were categorized as vitamin D deficient if 25-OH vitamin D was <50nmol/L, or normal if vitamin D was ≥50nmol/L. Biochemical parameters, bone mineral densitometry (BMD), and urinary tract and neck ultrasonography were assessed. RESULTS: In the study group, 66 (51.6%) patients had vitamin D deficiency and 60 (48.4%) had normal vitamin D levels. Nephrolithiasis and osteoporosis were found in 26.6% and 30.5% of subjects, respectively. The prevalence of metabolic syndrome (MetS), obesity (BMI≥30kg/m2) and hypertension (HTN) were higher in the vitamin D deficient group when compared to the normal group (p=0.04, p=0.01 and p=0.03, respectively). There was no difference regarding the presence of nephrolithiasis and osteoporosis between the groups. The mean adenoma size was similar in both groups. CONCLUSIONS: Vitamin D deficiency was not associated with osteoporosis, nephrolithiasis, adenoma size or biochemical parameters in PHPT. However, vitamin D deficiency may be a risk factor for developing HTN and MetS in PHPT.

Thiol-disulfide homeostasis and ischemia-modified albumin as a marker of oxidative stress in patients with sarcopenia.

AIM: Sarcopenia is characterized by progressive and generalized loss of skeletal muscle mass and strength. Chronic inflammatory conditions and increased oxidative stress are in the pathogenesis of sarcopenia. Our aim was to evaluate the relationship between sarcopenia and thiol-disulfide homeostasis and ischemia-modified albumin levels as an oxidative stress marker. METHODS: Patients aged ≥65 years were recruited in this study. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People criterion. Total thiol, native thiol, disulfide and ischemia-modified albumin levels were measures according to clinical and laboratory features. Patients were divided into two groups according to their sarcopenia presence; thiol-disulfide homeostasis and ischemia-modified albumin levels were evaluated between these groups. RESULTS: Overall, 94 patients were analyzed. The mean age was 75.0 ± 6.71 years. A total of 39% of the patients were diagnosed as probable sarcopenia, 3.2% had sarcopenia, 6.4% had severe sarcopenia and 51.1% were diagnosed as normal. The levels of native thiol, total thiol, disulfide level and disulfide-native thiol, native thiol-total thiol and disulfide-total thiol ratios were similar in patients with sarcopenia when compared with the control group. In addition, there were no differences between albumin and ischemia-modified albumin levels. In univariate regression analysis, handgrip strength was found to be an independent predictor of native thiol and total thiol, and disulfide levels. CONCLUSION: This is the first study in the literature that evaluates the thiol-disulfide homeostasis and ischemia-modified albumin levels in sarcopenic older patients. Long-term studies are warranted to confirm the relationship between oxidative stress markers and sarcopenia. Geriatr Gerontol Int 2021; 21: 584-589.

Insomnia and falls in older adults: are they linked to executive dysfunction?

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.

Long-term effect of masked hypertension management on cognitive functions in geriatric age: geriatric MASked hypertension and cognition follow-up study (G-MASH-cog MONITOR).

OBJECTIVES: Masked hypertension, defined as nonelevated clinic blood pressure with elevated out of clinic blood pressure, has been associated with increased cardiovascular events, mortality and cognitive impairment. No evidence exists regarding the effect of treating masked hypertension. In this study, we followed-up the patients in the G-MASH-cog study for 1 year and aimed to examine the effect of the management of masked hypertension on cognitive functions. METHODS: The G-MASH-cog study participants were followed-up for 1 year. In masked hypertensive individuals, lifestyle modification and antihypertensive treatment (perindopril or amlodipine) were initiated for blood pressure control. Measurements of cognitive tests and ambulatory blood pressure monitoring at baseline and at 1-year follow-up were compared. RESULTS: A total of 61 patients (30 in masked hypertension group; 31 in normotensive group) were included. Mean age was 72.3 ± 5.1 and 59% of the participants were female. Compared with baseline ambulatory blood pressure measurement results, patients with masked hypertension had significantly lower ambulatory blood pressure measurement results after 1-year follow-up. The quick mild cognitive impairment test (Q-MCI-TR) score increased with antihypertensive treatment (Q-MCI score at baseline = 41(19-66.5), at 1 year = 45.5 (22-70), P = 0.005) in masked hypertensive patients. In the final model of the mixed-effects analysis, when adjusted for covariates, interaction effect of the masked hypertension treatment with time was only significant in influencing the changes in Q-MCI scores over time in patients aged between 65 and 74 years (P = 0.002). CONCLUSIONS: Treatment of masked hypertension in older adults was associated with improvement in cognitive functions.

Impact of frailty and ultrasonography-based sarcopenia on the development of postoperative complications in gastrointestinal cancer patients

Background/aim: Gastrointestinal (GI) system cancers are frequent among older adults and it is still difficult to predict which are at increased risk for postoperative complications. Frailty and sarcopenia are increasing problems of older population and may be associated with adverse outcomes. In this study we aimed to examine the effect of sarcopenia and frailty on postoperative complications in older patients undergoing surgery for GI cancers. Materials and methods: Forty-nine patients admitted to general surgery clinic with the diagnosis of gastrointestinal system cancers were included in this cross-sectional study. Frailty status was assessed using the Edmonton Frail Scale (EFS). Sarcopenia was defined due to the EWGSOP2 criteria and ultrasonography was used to evaluate muscle mass. Results: The median age of the patients was 70 (min-max: 65­87). Fourteen (28.6%) patients were found to be sarcopenic and 16 (32.7%) patients were frail, and 6 (37.5%) of these patients were also severe sarcopenic (p = 0.04). When the postoperative complications were assessed, time to oral intake, time to enough oral intake, length of hospital stay in the postoperative period were found to be longer in frail patients (p = 0.02, p = 0.03, p = 0.04 respectively). Postoperative complications were not different due to the sarcopenia. Conclusion: Frailty, but not sarcopenia was associated with adverse outcomes in older adults undergoing GI cancer surgery. Comprehensive geriatric assessment before surgical intervention may help to identify patients who are at risk.

Ultrasonography versus bioelectrical impedance analysis: which predicts muscle strength better?

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 index (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.

STAR-Sonographic Thigh Adjustment Ratio: A Golden Formula for the Diagnosis of Sarcopenia.

OBJECTIVE: The aim of the study was to explore an individualized sonographic muscle thickness ratio and its cutoff values in the diagnosis of sarcopenia. DESIGN: A total of 326 community-dwelling adults were included in this cross-sectional study. Total skeletal muscle mass was evaluated by bioelectrical impedance analysis, and nine-site muscle thickness measurements using ultrasound. Isometric handgrip and knee extension strengths were assessed. Physical performance was evaluated by usual Gait Speed, Chair Stand Test, and Timed Up and Go Test. RESULTS: Because the anterior thigh muscle thickness was the most significantly decreasing measurement with aging and the most significantly related value with body mass and height; sonographic thigh adjustment ratio was calculated by dividing it with body mass index. Using the two standard deviation values of our healthy young adults, sonographic thigh adjustment ratio cutoff values were found as 1.4 and 1.0 for male and female subjects, respectively. Sonographic thigh adjustment ratio values were negatively correlated with Chair Stand Test and Timed Up and Go Test in both sexes (all P < 0.05) and positively correlated with gait speed in female subjects and knee extension strength in male subjects (both P < 0.05). CONCLUSIONS: Our results imply that regional (rather than total) muscle mass measurements should be taken into consideration for the diagnosis of sarcopenia.

Role of Ultrasonography in Estimating Muscle Mass in Sarcopenic Obesity.

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/m2 ) 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 cm2 , 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.

Impact of atrial fibrillation on frailty and functionality in older adults.

BACKGROUND AND AIM: Atrial fibrillation (AF), the most common sustained arrhythmia in older adults, causes significant complications such as stroke, dementia, and decreased quality of life. Frailty is a geriatric syndrome that is associated with increased risk of poor clinical outcomes including falls, disability, and mortality. We aimed to investigate the relationship between AF and frailty and functionality in older adults. METHODS: A total of 123 patients 64 with AF and 59 with normal sinus rhythm were enrolled in the study with cross-sectional design. All patients underwent comprehensive geriatric assessment (CGA). Frailty status was assessed using Fried criteria and FRAIL scale. The brief Older People's Quality of Life questionnaire was applied for quality of life. Results of the laboratory tests were recorded and compared for both groups. RESULTS: Although the frequency of frailty status determined by the Fried criteria and the FRAIL scale was higher in the AF group, this difference was not statistically significant. However, it was found that there was a positive correlation between the European Heart Rhythm Association (EHRA) AF symptom score and frailty according to the FRAIL scale (Goodman and Kruskal gamma coefficient = 0.39, p = 0.020). Comorbidities and polypharmacy were more common in the AF group (p < 0.001, both). CGA revealed lower Lawton-Brody Instrumental Activities of Daily Living scores (p = 0.024), higher fall rates in the previous year (p = 0.016), and slower walking speed (p = 0.020) in the AF group. Total cholesterol, LDL, HDL, total protein, albumin, and prealbumin were lower; brain natriuretic peptide (BNP) and C-reactive protein (CRP) levels were higher in the AF group. CONCLUSIONS: EHRA AF symptom severity score is positively correlated with frailty. AF is associated with worse metabolic profile and clinical features on CGA that AF might be a frailty marker. Frailty should be investigated in AF patients.

Timing of Dysphagia Screening in Alzheimer's Dementia.

BACKGROUND: Dysphagia is an important and frequent symptom in Alzheimer's dementia (AD). We hypothesized that dysphagia could be seen in the early stages of AD and sarcopenia presence rather than the severity of the AD affecting dysphagia. The main aim of this study was to investigate swallowing functions in AD patients according to stages. The second aim was to investigate the correlation between sarcopenia and dysphagia in AD. METHODS: This study involved 76 probable AD patients. For all participants, diagnosis of sarcopenia was based on definitions from the revised version of European Working Group on Sarcopenia in Older People at 2018. Dysphagia symptom severity was evaluated by the Turkish version of the Eating Assessment Tool, a videofluoroscopic swallowing study (VFSS) was performed for instrumental evaluation of swallowing. The patients were divided into 3 groups according to the clinical dementia rating (CDR) scale as CDR 1 (mild dementia), CDR 2 (moderate dementia), and CDR 3 (severe dementia). Swallowing evaluation parameters were analyzed between these groups. RESULTS: Mean age was 78.9 ± 6.4 years, and 56.4% were female. Twenty-six patients had mild dementia, 31 patients had moderate dementia, 19 patients had severe dementia (CDR 3). We found that sarcopenia rates were similar between AD stages according to CDR in our study population and dysphagia could be seen in every stage of AD. In a multivariate analysis, polypharmacy and sarcopenia were found to be independently associated factors for dysphagia, irrespective of stage of AD (OR: 6.1, CI: 1.57-23.9, P = 0.009; OR: 4.9, CI: 1.24-19.6, P = 0.023, respectively). CONCLUSION: Aspirations may be subtle so that AD patients and caregivers may not be aware of swallowing difficulties. Therefore, all AD patients, especially those who have polypharmacy and/or sarcopenia (probable-sarcopenia-severe sarcopenia), should be screened for dysphagia in every stage.

Turkish validation of a new scale from older people's perspectives: Older people's quality of life-brief (OPQOL-brief).

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.

Clinical Impact of p27Kip1 and CaSR Expression on Primary Hyperparathyroidism.

We aimed to investigate the expressions of p27 kinase inhibitory protein 1 (p27Kip1) 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 p27Kip1 were performed in surgical specimens. Clinical features, biochemical parameters, and BMD measurements of patients with PHPT were evaluated retrospectively. Expressions of p27Kip1 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 p27Kip1 and CaSR expressions, serum calcium, plasma parathormone, 25-hydroxy vitamin D levels, and bone density (p > 0.05). The expressions of p27Kip1 and CaSR were decreased in PHPT patients. This reduction may play an important role in the pathogenesis of PHPT. However, neither p27Kip1 nor CaSR expression was found to be useful in predicting prognosis or severity of disease.
