RESUMEN
PURPOSE: To investigate sarcopenia and related factors and to determine the disease-specific phase angle (PhA) cut-off score in detecting sarcopenia in elderly patients with Parkinson's Disease (PD). METHODS: This cross-sectional study was conducted with 89 participants. The Mini-Nutritional Assessment (MNA), the Eating Attitude Test-10 (EAT-10), the Physical Activity Scale for The Elderly (PASE) questionnaire and the Hoehn-Yahr scale have been used. Additionally, anthropometric measurements were performed. The diagnosis of sarcopenia was based on the new consensus published by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2). PhA has been performed by Bioelectrical Impedance Analysis (BIA) with Tanita MC 780®. RESULTS: The mean age was of the participants 68.9 ± 6.4 years, and 57.3% were male. The prevalence of sarcopenia was 12.3%. PhA, malnutrition, age, disease severity, low calf circumference (CC), low body mass index (BMI), the difference between the pre-diagnosis and current weight loss, dopaminergic treatment, and low PASE score were associated with sarcopenia. The cut-off value of the PhA in terms of the ability to identify sarcopenia was <4.5o with a sensitivity of 53.3% and a specificity of 93.2% (p = 0.001). When we grouped the PhA of the patients according to this cut-off score, it was seen that 14.6% of them were sarcopenic. Age, disease severity, PASE score and hand grip strength were significantly related to both sarcopenia and PhA. CONCLUSION: It is important to be aware of sarcopenia and related factors at an early stage in Parkinson's patients. Because of disease-related symptoms, it may be more appropriate to use a disease-specific PhA cut-off score in the definition of sarcopenia.
RESUMEN
AIM: Swallowing is a vital activity. The difficulty while swallowing, referred to as swallowing disorder, is strongly associated with serious health problems in the elderly. The aim of this study is to enable early recognition of the swallowing function developing as an asymptomatic condition. METHOD: Our study was conducted on elderly populations aged 65 years and over who met the exclusion criteria. Firstly, to be able to reach the number of sampling, "EAT-10 questionnaire", which also has a Turkish validation, was used to eliminate those with symptomatic swallowing disorders. The number of patients we reached was 320, but 7 dropped out of the study and therefore the study was carried out with a total of 313 [reached as 97.8% (up 95% G-power)]. RESULT: We used validated sEMG test in the quantitative (objective) detection of asymptomatic swallowing disorder. In this method, asymptomatic swallowing disorder was detected in 39 cases (12.4%). CONCLUSION: Swallowing disorder without symptoms is frequent and the sEMG test is useful in detecting it in the elderly population.

Background/aim: The purpose of this study was to determine sarcopenia, sarcopenic obesity and phase angle (PA) and the influence of chemotherapy (CT) on anthropometric measurements and and the PA in in geriatric patients with gastrointestinal (GI) cancer. Materials and methods: The anthropometric measurements, calf circumference (CC), upper midarm circumference (UMAC), and hand grip strength (HGS), have been measured to understand muscle function of 153 patients (mean age of 70.5 ± 5.6 years, 28.8% female, 71.2% male). Sarcopenia and PA measurements have been evaluated by bioelectrical impedance analyses. The same evaluations were checked again after 1 cycle of CT (min: 4, max: 6 weeks). Results: Patient population consisted of colorectal (51,6%), gastric (26.8%), pancreas (11.8%), liver (7.2%), and biliary tract cancer (2%). UMAC (28.5 ± 4.4 before, 28.1 ± 4.9, P = 0.034 after CT), and HGS measurements (27.5 ± 8.6 before, 26.8 ± 8.8 after CT, P = 0.007) have significantly decreased after CT. CC measurement < 31 cm at first visit was seen in 13.1% of patients, but the ratio raised to 20.3% after CT (χ², P = 0.003). Severe sarcopenia was determined in 33% of all patients, and 30.0% of them have been considered as sarcopenic obese. Conclusion: Sarcopenia and sarcopenic obesity were prevalent in this group patients. The CT caused a decrease in muscle functions, UMAC, and CC. Patients should be followed up carefully for sarcopenia, sarcopenic obesity, and nutritional aspect and it would be proper to intervene before sarcopenia has not occurred yet.

OBJECTIVE: The aim of this study was to investigate the prevalence of delirium and its association with mortality rates in elderly inpatients. METHODS: The medical records of 1435 patients over 65 years old who were treated at a regional university hospital and were referred to the university's Consultation and Liaison Psychiatry Clinic for psychological evaluation were retrospectively analyzed. Patients with and without a diagnosis of delirium were compared. The National Survival Database was used to determine mortality rates. RESULTS: The prevalence of delirium was 25.5%. The delirium group was older (p < .0001) and had a larger proportion of males (p < .0001). Mortality rate was higher in the delirium group at 1, 2, 3, 4, and 5 years (p < .0001 for all). Age, gender, lower urinary system diseases, chronic liver disease, solid hematologic malignancy, infections, and Alzheimer's disease emerged as significant parameters associated with mortality. Multivariate analysis of these parameters indicated that comorbid diseases (lower urinary system diseases, chronic liver disease, solid hematologic malignancy, infections, and Alzheimer's disease) are risk factors for mortality independent of demographic data such as age and gender. CONCLUSIONS: Independent of all other factors, delirium is associated with higher mortality risk.

PURPOSE: Malnutrition is one of the most important geriatric syndromes in the elderly. The aim of this study was to investigate the association between anemia and malnutrition in elderly nursing home residents. MATERIALS AND METHODS: Local nursing home residents over 60 years old in the Izmir were included in the study. Blood samples were taken from study participants for hemogram, iron, ferritin, total iron-binding capacity, vitamin B12 and folic acid analysis. WHO criteria were used to define anemia. Causes of anemia were classified as iron deficiency, vitamin B12 or folic acid deficiency, anemia of chronic disease or other hematologic causes. Anemia was defined as the dependent variable and malnutrition was defined as the independent variable. Correlation between MNA scores and Hb levels was determined using Pearson correlation analysis. The slope of causality between malnutrition and anemia was determined using the χ (2) test and logistic regression analysis. RESULTS: The study included 257 elderly nursing home residents with a mean age of 78.5 ± 7.8 years. The overall prevalence of anemia was 54.9 %; 35.8 % of the study participants were at risk of malnutrition and 8.2 % were malnourished. Anemia risk was 2.12-fold higher in participants at risk of malnutrition and 5.05-fold higher in those with malnutrition. In the participants with malnutrition or malnutrition risk, the most common cause of anemia was anemia of chronic disease (57.1 and 46.5 %, respectively). CONCLUSION: The prevalence of anemia among elderly nursing home residents is high in Turkey. Malnutrition and malnutrition risk increase the incidence of anemia.

PURPOSE: It is well established that diabetic peritoneal dialysis (PD) patients have a higher mortality rate than the other PD population. This study was designed to determine the overall predictors of survival and compared mortality and morbidity between diabetic and non-diabetic Turkish PD patients. METHODS: We conducted a multicenter retrospective study with 915 PD patients [217 had diabetes mellitus (DM)]. Serum albumin, PTH, HbA1c, co-morbid diseases, dialysis adequacy (Kt/V), and peritoneal transport characteristics as well as peritonitis episodes and ultrafiltration failure during the follow-up period were recorded. RESULTS: DM patients were older and had more co-morbidities than non-DM patients. Peritonitis rates were higher in DM patients (one episode per 35.9 patient months) compared to non-DM patients (one episode per 41.5 patient months) (p < 0.001). On Kaplan-Meier analysis, patient survival was significantly lower in DM patients with the 2-, 3- and 5-year patient survival rates of 90.8%, 87.8% and 78.2% in non-diabetics and 80.9%, 70.4% and 61.2% in diabetics, respectively. On Cox regression analysis, DM (HR 1.5, p = 0.022), age (HR 1.03, p < 0.001), baseline serum albumin (HR 0.39, p < 0.001), heart failure (HR 0.038, p = 0.038), peripheral artery disease (HR 1.83, p = 0.025) and amputation (HR 4.1, p = 0.009) at baseline were significant predictors of overall mortality. CONCLUSIONS: Patient survival is lower in diabetic compared to non-diabetic patients on PD. Peritonitis rates were also higher in diabetic PD patients. DM, older age, albumin level and cardiovascular co-morbidities are predictors of mortality.

BACKGROUND: The objectives of this study were to examine the prevalence and risk of pressure ulcers (PrUs) among hospitalized patients 65 years or older in a university hospital setting and to assess the potential for prevention and healing in that population. METHODS: The retrospective study conducted at the general medicine departments of Ege University Hospital in Izmir, Turkey, included 209 patients (115 females, 94 males) 65 years or older, who had been admitted to the hospital for a variety of reasons between April 1, 2011, and October 1, 2011. The following tools were used to collect data: a data collection form to identify the sociodemographic and medical characteristics of the patients, the Braden Risk Assessment Scale to assess the risk of PrUs, and a form to monitor PrUs, which included the site of the PrU, the category, and the PUSH (Pressure Ulcer Scale for Healing) score, a tool for tracking changes in PrUs status applied at weekly intervals. RESULTS: The mean patient age was 73 (6.4) years. The prevalence of PrUs was 5.8% during the hospital stay. Pressure ulcers appeared most frequently in the ischeal tuberosity area (40%), and 45.2% of all PrUs observed were category II. The comorbidities of the patients who had PrUs were as follows: rheumatoid arthritis, 40% (n = 5); acute renal failure, 24% (n = 3); multiple myeloma, 8% (n = 1); chronic renal failure, 8% (n = 1); pneumonia, 8% (n = 1); and acute lymphoblastic leukemia, 8% (n = 1). CONCLUSIONS: Pressure ulcers are a common healthcare complication in the older adult population, with potentially severe consequences. The most important intervention that healthcare professionals can make to reduce PrUs is to determine and address risk factors.

Background: The prognostic nutritional index (PNI) and the systemic immune inflammation index (SII) have been used as simple risk-stratification predictors for COVID-19 severity and mortality in the general population. However, the associations between these indices and mortality might differ due to age-related changes such as inflammaging and several comorbid conditions in older patients. Therefore, we aimed to compare the predictivity of the PNI and SII for mortality among hospitalized older patients and patients under 65 years old. Methods: Patients hospitalized with COVID-19 from March 2020 to December 2020 were retrospectively included. The PNI and SII were calculated from hospital records within the first 48 h after admission. Data were evaluated in the whole group and according to age groups (≥65 < years). Receiver operating characteristic curves were drawn to evaluate the predictivity of the PNI and SII. Results: Out of 407 patients included in this study, 48.4% (n = 197) were older patients, and 51.6% (n = 210) were under 65 years old. For mortality, the area under the curve (AUC) of the PNI and SII in the adult group (<65 years) was 0.706 (95% CI 0.583-0.828) (p = 0.003) and 0.697 (95% CI 0.567-0.827) (p < 0.005), respectively. The AUC of the PNI and SII in the older group was 0.515 (95% CI 0.427-0.604) (p = 0.739) and 0.500 (95% CI 0.411-0.590) (p = 0.993). Conclusions: The accuracy of the PNI and SII in predicting mortality in adult COVID-19 patients seemed to be fair, but no association was found in geriatric patients in this study. The predictivity of the PNI and SII for mortality varies according to age groups.
RESUMEN
INTRODUCTION: Nephrotic syndrome (NS) is one of the reasons of end-stage kidney disease, and elucidating the pathogenesis and offer new treatment options is important. Oxidative stress might trigger pathogenesis systemically or isolated in the kidneys. Octreotide (OCT) has beneficial antioxidant effects. We aimed to investigate the source of oxidative stress and the effect of OCT on experimental NS model. METHODS: Twenty-four non-uremic Wistar albino rats were divided into 3 groups. Control group, 2 mL saline intramuscular (im); NS group, adriamycin 5 mg/kg intravenous (iv); NS treatment group, adriamycin 5 mg/kg (iv) and OCT 200 mcg/kg (im) were administered at baseline (Day 0). At the end of 21 days, creatinine and protein levels were measured in 24-hour urine samples. Erythrocyte and renal catalase (CAT) and thiobarbituric acid reactive substance (TBARS) were measured. Renal histology was also evaluated. RESULTS: There was no significant difference among the 3 groups in terms of CAT and TBARS in erythrocytes. Renal CAT level was lowest in NS group, and significantly lower than the control group. In treatment group, CAT level significantly increased compared with NS group. In terms of renal histology, tubular and interstitial evaluations were similar in all groups. Glomerular score was significantly higher in NS group compared with control group and it was significantly decreased in treatment group compared to NS group. CONCLUSIONS: Oxidative stress in NS might be due to the decrease in antioxidant protection mechanism in kidney. Octreotide improves antioxidant levels and histology in renal tissue and might be a treatment option.

INTRODUCTION: Encapsulated peritoneal sclerosis (EPS) is a devastating complication of peritoneal dialysis. We aimed to investigate the effects of mycophenolate mofetil (MMF) treatment in experimental EPS in rats. METHODS: 40 nonuremic Wistar albino rats were divided equally into 4 groups: control rats received 2 ml isotonic saline intraperitoneally daily for 3 weeks without any other treatment. The chlorhexidine gluconate group received intraperitoneally 2 ml/200 g injection of chlorhexidine gluconate and ethanol dissolved in saline for 3 weeks. The resting group received chlorhexidine gluconate (0 - 3rd week) + peritoneal resting (4th - 6th week). The MMF group received chlorhexidine gluconate (0 - 3rd week) + 125 mg/l MMF in drinking water (4th - 6th week). Dialysate cytokine levels, leukocyte count, peritoneal thickness, inflammation and fibroblast activities were evaluated. RESULTS: Although the MMF and resting groups showed beneficial effects on ultrafiltration and D1/D0 glucose compared to the chlorhexidine gluconate group, only MMF treatment improved dialysate TGFß1, VEGF and MCP-1 levels compared to the resting group. Inflammatory activity and vascularity observed in a tissue biopsy, including capillaries number per mm2 of submesothelial area, decreased in the treatment group. CONCLUSIONS: MMF treatment has beneficial effects on EPS via inhibiting inflammation and neovascularisation by reducing dialysate VEGF overexpression.

BACKGROUND: Chronic fluid overload (FO) is frequently present in peritoneal dialysis (PD) patients and is associated with hypertension and left ventricular hypertrophy and dysfunction, which are important predictors of death in dialysis patients. In the present study, we investigated the relationship between nutrition, inflammation, atherosclerosis and body fluid volumes measured by multi-frequency bioimpedance analysis (m-BIA) in PD patients. In addition, we analysed the relationship of extracellular volume values by m-BIA to echocardiographic parameters in order to define its usefulness as a measure of FO. METHODS: Ninety-five prevalent PD patients (mean age 50 ± 13 years, 10 of them diabetic) were enrolled. Extracellular water (ECW), total body water (TBW), dry lean mass (DLM) and phase angle (PA) were measured by m-BIA. Volume status was determined by measuring left atrium diameter (LAD) and left ventricular end-diastolic diameter (LVEDD). Measurement of carotid artery intima-media thickness (CA-IMT) was used to assess the presence of subclinical atherosclerosis. Serum albumin was used as a nutritional marker, and serum C-reactive protein (CRP) was used as an inflammatory marker. RESULTS: Mean ECW/height was 10.0 ± 1.0 L/m for whole group and 9.3 ± 0.6 L/m in patients with normal clinical hydration parameters. In correlation analysis, markers of nutrition, inflammation and atherosclerosis correlated well with m-BIA parameters. When we used echographically measured LAD (> 40 mm) or LVEDD (> 55 mm) as a confirmatory parameter, a cut-off value of 10.48 L/m ECW/height (78% specificity, with a sensitivity of 77% for LAD and 72% specificity, with a sensitivity of 70% for LVEDD) was found in ROC analysis for the diagnosis of FO. Patients with FO were older and had higher systolic blood pressure, cardiothoracic index, serum CRP level and mean CA-IMT than patients without FO. Patients with inflammation had higher CA-IMT values. In multivariate analysis, only two factors-low urine output and ECW/height-were independently associated with the presence of inflammation. CONCLUSIONS: FO defined by m-BIA is significantly correlated with markers of malnutrition, inflammation and atherosclerosis in PD patients. The indices obtained from m-BIA, especially ECW/height, correlated well with volume overload as assessed by echocardiography and might be a measure worth testing in a properly designed clinical study.

AIM: The aim of this study was to evaluate the effects of hemodialysis (HD) and peritoneal dialysis (PD) treatments on oxidative and nitrosative stress markers comparatively. METHODS: Twenty HD and 20 PD patients as well as 20 healthy individuals were included in this study. Plasma advanced oxidation protein products, myeloperoxidase, thiol group and 3-nitrotyrosine (3-NT) levels were measured in all subjects. RESULTS: Plasma advanced oxidation protein products and myeloperoxidase levels were elevated by HD and PD treatments when compared to the control group. Conversely, plasma thiol group levels were decreased in HD and PD patients. 3-NT levels were increased by HD treatment only. CONCLUSIONS: The elevated plasma 3-NT levels in pre-HD and post-HD patients suggest that those patients have a considerably increased risk for nitrosative tissue injury. However, similar 3-NT levels of the control and PD groups support the advantage of PD therapy in terms of nitrosative tissue injury.

Strict volume control strategy provides better cardiac functions and control of hypertension in dialysis patients. We investigated the effect of this strategy on mortality and technique failure in peritoneal dialysis patients over a 10-year period. 243 patients were enrolled. Strict volume control by dietary salt restriction and ultrafiltration was applied. Mean systolic and diastolic blood pressures decreased from 138.4 ± 29.9 and 86.3 ± 16.8 to 114.9 ± 32.3 and 74.7 ± 18.3 mm Hg, respectively. Overall and cardiovascular mortality rates were 48.4 and 29.6 per 1,000 patient-years, respectively. In multivariate analysis, age, diabetes and baseline serum albumin level were independent predictors of overall mortality, and age, diabetes and baseline serum calcium of cardiovascular mortality. Residual diuresis and peritoneal equilibration test values were not related to mortality. Strict volume control leads to lower mortality than comparable series in the literature. Technique survival is better during the first 3 years, but not after 5 years.

AIM: Encapsulated peritoneal sclerosis is characterized by neoangiogenesis and fibrosis. Octreotide, a somatostatin analogue is a well-known antifibrotic, antiproliferative and anti-angiogenic agent. The aim of the study is to evaluate the effects of octreotide in encapsulated peritoneal sclerosis-induced neoangiogenesis and fibrosis and compare the results with resting. METHODS: Non-uraemic Wistar-Albino male rats (n = 35) were divided into four groups. Group I, control rats, received 2 mL isotonic saline i.p. daily for 3 weeks. Group II, received daily i.p. 2 mL/200 g injection of chlorhexidine gluconate (0.1%) and ethanol (%15) dissolved in saline for 3 weeks. Group III, chlorhexidine gluconate for 3 weeks plus an additional 3 weeks without any treatment (rest), to a total of 6 weeks. Group IV, chlorhexidine gluconate for 3 weeks plus an additional 3 weeks octreotide, 50 mcg/kg bodyweight s.c., for a total of 6 weeks. RESULTS: Octreotide significantly reversed ultrafiltration capacity of peritoneum with decreasing inflammation, neoangiogenesis and fibrosis compared to the resting group. Octreotide also caused inhibition of dialysate transforming growth factor-ß1, vascular endothelial growth factor and monocyte chemotactic protein-1 activity and improved mesothelial cell cytokeratin expression. Peritoneal resting has no beneficial effects on peritoneum. CONCLUSION: In conclusion, octreotide may have a therapeutic value in peritoneal dialysis patients who suffer from encapsulated peritoneal sclerosis.

PURPOSE: The aim of this study was to determine the prevalence of sarcopenia according to different methods in older outpatients using regional threshold values of muscle mass and muscle strength. METHODS: We used data from our university hospital's geriatric outpatient clinic specific to endocrinological problems, retrospectively. Sarcopenia was defined according to European Working Group on Sarcopenia in Older People (EWGSOP)1 and EWGSOP2 criteria using regional threshold values of skeletal muscle mass (SMM) with the use of different adjustments, and also according to EWGSOP2 with regional threshold values of grip strength. RESULTS: Among 248 study participants, 53.6% were obese. There was no sarcopenic patient with the height square adjusted regional SMM thresholds for EWGSOP1 and EWGSOP2. Sarcopenia prevalence was 11.7% with EWGSOP2, and 41.1% by the use of regional grip strength thresholds for EWGSOP2 with body mass index adjustments for SMM. The comparison of EWGSOP1 versus EWGSOP2 was not possible due to lack of sarcopenic patients with height adjustment. CONCLUSIONS: The prevalence of sarcopenia varied significantly with the application of different adjustment methods for SMM, and the use of regional grip strength thresholds in the specific patient group with normal to overweight and obese individuals. The use of regional thresholds of grip strength increased the prevalence of EWGSOP2-defined sarcopenia. The impact of the adjustment methods, the characteristics of the study population, and the regional thresholds should be taken into consideration while evaluating the results of sarcopenia studies.

As the older population steadily grows, a corresponding increase in elderly suicides is also expected. In addition, due to differences in the physical and psychosocial characteristics of this age group, the characteristics of elderly suicides are predicted to be different to those of other groups. In this study, we aimed to report the characteristics of suicides 60 years and older according to sex and age subgroups. We retrospectively reviewed the autopsy reports of individuals aged 60 and older who committed suicide in Turkey during the 10-year period between 2005 and 2014. Their age, sex, cause of death, and year, month, season, place, and method of suicide were analyzed. Comparisons were made based on sex, age subgroup, demographic variables, and descriptive characteristics of the suicides. Of 17,942 forensic autopsies, 525 were elderly suicides. Of these, 77.3% were men and the mean age was 71.26 ± 8.16 (range, 60-94) years. There were statistically significant differences in suicide method according to sex (p < 0.001, X = 43.984) and age subgroups (p = 0.001, X = 51.457). For both sexes, hanging was the most common suicide method (59.4%) and the majority of suicides occurred at home (73.1%). The suicides occurred more frequently in the 65-74 age subgroup, in the summer, and in the months of June and July. Identifying the characteristics of elderly suicides, especially by sex and age subgroups, may be beneficial for suicide risk assessment and the development of prediction and prevention programs.

Coronary artery disease is a major cause of death in patients with a renal dysfunction. Among the patients who undergo coronary artery bypass grafting, renal dysfunction is known to be a major predictor of in-hospital and out-of-hospital mortality. From 2004 to 2007, we performed elective open-heart surgeries on 2380 patients in whom there was no primary renal failure. Of those patients, only 185 in whom acute renal failure (ARF) was developed were included in the study. The patients were divided into 2 groups: a late dialysis group (n=90) and an early dialysis group (n=95). The mean age of the patients was 62.3+/-6.4 in the late dialysis group and 64.5+/-5.2 in the early dialysis group. There were 32 female and 58 male patients in the late dialysis group and 36 female and 59 male patients in the early dialysis group. Acute renal failure developed only in 185 patients out of 2380 open-heart surgery patients. The overall mortality in the 2380 open-heart surgery patients was 1.97%. Mortality among the ARF patients was 5.9%. However, there was no significant difference in hospital mortality between the 2 groups. Major complications, such as postoperative pneumonia, prolonged ventilation time, arrhythmia, the number of times postoperative hemodialysis was performed, development of chronic renal failure, time spent in the intensive care unit and the period of hospitalization, sepsis, and low cardiac output, were significantly higher in the late dialysis group. There was no difference in mortality between the 2 groups. Early dialysis for open-heart surgery patients who develop ARF postoperatively does not decrease mortality. However, it decreases morbidity, the amount of time spent in intensive care, and the period of hospitalization and thus reduces patient costs.

OBJECTIVES: To determine the prevalence of sarcopenia and related factors in individuals aged ≥65 years living in the Bornova district of Izmir, Turkey. Sarcopenia is one of the most serious health problems among elderly individuals. METHODS: This cross-sectional study was conducted in the Bornova district of Izmir, Turkey, between February-July 2015. This study participants were comprised of 909 individuals aged ≥65 years. The dependent variable was the presence of sarcopenia and the European Working Group on Sarcopenia in Older People (EWGSOP) approach was used for determining sarcopenia. The independent variables were socio-demographic and economic characteristics, healthy life behaviors and health status/condition. Data were collected at home through face-to-face interviews and measurements, analysed using chi-square test, t-test and logistic regression analysis. RESULTS: The participants' mean age was 72.8±6.2 (range: 65-100) years, and 60.2% were female (n=582). The prevalence of sarcopenia was 5.2% and that of low gait speed was 41.0%, low grip strength was 57.0%, low calf circumference was 6.1% and the combination of low gait speed and low grip strength was 14.3%. Risk factors of sarcopenia included increasing age, physical inactivity, low body mass index and the presence or risk of malnutritionConclusion: The prevalence of sarcopenia was 5.2% in this population and increased with age, physical inactivity, low body mass index and the presence or risk of malnutrition.

Abstract Introduction: Nephrotic syndrome (NS) is one of the reasons of end-stage kidney disease, and elucidating the pathogenesis and offer new treatment options is important. Oxidative stress might trigger pathogenesis systemically or isolated in the kidneys. Octreotide (OCT) has beneficial antioxidant effects. We aimed to investigate the source of oxidative stress and the effect of OCT on experimental NS model. Methods: Twenty-four non-uremic Wistar albino rats were divided into 3 groups. Control group, 2 mL saline intramuscular (im); NS group, adriamycin 5 mg/kg intravenous (iv); NS treatment group, adriamycin 5 mg/kg (iv) and OCT 200 mcg/kg (im) were administered at baseline (Day 0). At the end of 21 days, creatinine and protein levels were measured in 24-hour urine samples. Erythrocyte and renal catalase (CAT) and thiobarbituric acid reactive substance (TBARS) were measured. Renal histology was also evaluated. Results: There was no significant difference among the 3 groups in terms of CAT and TBARS in erythrocytes. Renal CAT level was lowest in NS group, and significantly lower than the control group. In treatment group, CAT level significantly increased compared with NS group. In terms of renal histology, tubular and interstitial evaluations were similar in all groups. Glomerular score was significantly higher in NS group compared with control group and it was significantly decreased in treatment group compared to NS group. Conclusions: Oxidative stress in NS might be due to the decrease in antioxidant protection mechanism in kidney. Octreotide improves antioxidant levels and histology in renal tissue and might be a treatment option.
Resumo Introdução: Síndrome nefrótica (SN) é uma das causas de doença renal em estágio terminal. É importante elucidar a patogênese e oferecer novas opções de tratamento. Estresse oxidativo pode desencadear a patogênese sistemicamente ou isoladamente nos rins. O octreotide (OCT) tem efeitos antioxidantes benéficos. Nosso objetivo foi investigar a fonte de estresse oxidativo e efeito do OCT no modelo experimental de SN. Métodos: Dividimos 24 ratos albinos Wistar não urêmicos em 3 grupos. Grupo controle, 2 mL de solução salina intramuscular (im); grupo SN, adriamicina 5 mg/kg intravenosa (iv); grupo tratamento SN, adriamicina 5 mg/kg (iv) e OCT 200 mcg/kg (im) foram administrados no início do estudo (Dia 0). Aos 21 dias, mediram-se os níveis de creatinina e proteína em amostras de urina de 24 horas. Mediu-se a catalase (CAT) eritrocitária e renal e a substância reativa ao ácido tiobarbitúrico (TBARS). Avaliou-se também histologia renal. Resultados: Não houve diferença significativa entre os três grupos em termos de CAT e TBARS em eritrócitos. O nível de CAT renal foi menor no grupo SN e significativamente menor que no grupo controle. No grupo tratamento, o nível de CAT aumentou significativamente em comparação com o grupo SN. Quanto à histologia renal, as avaliações tubular e intersticial foram semelhantes em todos os grupos. O escore glomerular foi significativamente maior no grupo SN em comparação com o grupo controle e diminuiu significativamente no grupo de tratamento em comparação com o grupo SN. Conclusões: Estresse oxidativo na SN pode ser devido à diminuição do mecanismo de proteção antioxidante nos rins. O octreotide melhora níveis de antioxidantes e histologia do tecido renal e pode ser uma opção de tratamento.
RESUMEN
PURPOSE: The purpose of this methodological study was to assess the validity and reliability of Turkish version of the "Edmonton Frail Scale" (EFS). METHOD: 130 individuals aged 65 and over residing at the Izmir Narlidere Nursing Home between September 2011 - April 2012 who agreed to participate in the study constituted the sample for the research. Individuals with communication problems (deafness, blindness or language barriers) and problems with manual dexterity were not included in the study. The EFS is composed of 11 items, with a minimum score of zero and a maximum score of 17. Initially, the scale was translated into Turkish and then back translated in order to ensure language equivalence. Six experts were consulted with regard to content validity and agreement among the experts was assessed using Kendall's W. When testing the reliability of the EFS, the scale was re-administered to 30 participants two-three weeks after the initial administration in order to determine its consistency over time and agreement between the first and second administration was analysed using the kappa statistic. Pearson's Moment Correlation Coefficient and Cronbach's Alpha were also used to establish reliability. FINDINGS: The overall Cronbach's alpha value for the scale was 0.75. An "item analysis" calculated item-total correlation coefficients of between 0.12-0.65 for scale items, and the item-total correlation for item six was found to be less than 0.20. This item solicits the number of medications used by the subject, and since the number of medications used is significant in the determination of frailty it was not removed from the scale. The scale was found to be highly consistent over time (Kappa (κ)â¯=â¯Min: 0.95, Max: 1.00) CONCLUSION: EFS indicators were found to be sufficiently reliable and valid for the Turkish population. Accordingly, it is recommended that this scale be used in determining the frailty of older individuals.
