RESUMEN
INTRODUCTION: Hypertension is an important risk factor for dementia as much as the morbidity and mortality of cardiovascular disease. Sustained hypertension is also more related to that risk. The aim of the study was to determine the relationship between 24-h ambulatory blood pressure monitoring (ABPM) and cognitive functions in elderly hypertensive patients without comorbid diseases which may deteriorate cognitive functions. MATERIALS AND METHODS: Ninety-one patients (21 male, 72.5 ± 8.1;70 female, 71.7 ± 7.7) above 60 years old previously diagnosed as hypertensive (HT) have been included to this study. The ABPM was performed after standardized mini mental test (sMMT) and geriatric depression scale (GDS) has been examined. The patients were divided into the groups as dipper/nondipper and regulated/nonregulated. The sMMT scores of the groups were compared. RESULTS: There was no statistical difference in average sMMT scores and distribution of mini mental groups between the dipper and nondipper groups. Hypertension regulation and mini mental measurements of the studied groups were moderately suggestive in the same direction (r = 0.333, p = 0.001). DISCUSSION AND CONCLUSION: There is an association between tension regulation and cognitive functions in elderly patients who have primary HT, but no relationship have been found between being nondipper and low cognitive function. Our results suggested that this study is critically important by means of revealing that the studies which are perceived distinctly about HT and cognitive functions need further evaluation with subgroup analyses in selected patient groups.

BACKGROUND/OBJECTIVES: Sarcopenia and sarcopenic obesity (SO) are geriatric syndromes leading to physical disability, poor quality of life and death. The aim of this study was to investigate the prevalence of sarcopenia and SO in nursing homes in Turkey and to define local disparities for diagnosing sarcopenia and SO. SUBJECTS/METHODS: This cross-sectional multicenter study was performed in 711 patients in 14 nursing homes. Comprehensive geriatric assessment tests, handgrip strength and calf circumference (CC) measurements were carried out. Sarcopenia was both defined by handgrip strength and CC criteria. RESULTS: According to handgrip strength measurement, 483 (68%) of patients were sarcopenic (male: 72%, female: 63.8%), 228 were non-sarcopenic. The prevalence of SO was 22% (13.7% in men, 30.2% in women). Patients (82.5%) who were diagnosed as sarcopenic by the handgrip strength test were not sarcopenic according to CC sarcopenia criteria. Therefore, we tried to determine the optimal CC value for diagnosing sarcopenia in our population. CONCLUSIONS: Both sarcopenia and SO were prevalent among Turkish nursing home elderly residents. Most of the patients with sarcopenia were obese or overweight. We showed that diagnosing sarcopenia with CC measurement underestimated the sarcopenia prevalence assessed by handgrip strength. So we concluded that, although different assessment methods are recommended for the diagnosis of sarcopenia local disparities should be considered.

OBJECTIVES: To analyse the most common MEFV (Mediterranean fever gene) mutations and polymorphisms in an elderly population free of chronic inflammatory disease (n=164), and explore possible associations between hsCRP (high sensitive C-reactive protein) and RF (rheumatoid factor) levels with MEFV mutations and polymorphisms. METHODS: An elderly group free of chronic inflammatory disease was chosen among the outpatients of the division of geriatric medicine. Total genomic DNA was isolated from blood, and PCR-RFLP analysis was performed using established protocols. Sera were analyzed for hsCRP and RF levels. RESULTS: The frequencies for 694V (1.8%), 694I (1.8%), 680I (0.6%), 726A (2.1%) and 148Q (5%) alleles were found to be similar to Turkish historic controls, with a carrier frequency of 1/4. Further analyses with rheumatoid factor (RF) levels and mutations revealed a significant association between the presence of the E148Q polymorphism with increased RF levels (>15 mg/dl) (xi2= 7.358, p=0.007, OR=5.41 95% CI 1.41-20.64). CONCLUSIONS: Common MEFV mutations and polymorphisms were similarly represented among the elderly population compared to historic controls. On the other hand, a significant association was found between the presence of E148Q polymorphism and increased RF levels. This suggests that the previously noted increased RF levels in elderly populations may somehow be related to the now described association of RF with MEFV E148Q polymorphism.

Retroperitoneal fibrosis (RPF) is an uncommon disorder that may cause ureteric obstruction with renal damage. Pergolide, a dopaminergic agonist used in the treatment of Parkinson's disease, has rarely been related to the development of RPF. We report on a 78-year-old woman with Parkinson's disease who presented with hydroureteronephrosis and developed RPF and serosal fibrosis during treatment with pergolide. Following discontinuation of pergolide therapy and placement of a double-J stent, her renal function improved. Inflammatory markers returned to normal limits within two months and the retroperitoneal fibrotic mass became smaller.

Effects of aging and hypercholesterolemic diet on lipid peroxidation and antioxidant status were investigated in rats. The rats were divided into four groups of ten: Group I; young rats receiving standard lab chow; Group II; young rats on hypercholesterolemic diet (0.4 g/rat/day); Group III; aged rates receiving standard lab chow; Group IV; aged rats on hypercholesterolemic diet (0.4 g/rat/day). Plasma lipid peroxidation end product level was determined as thiobarbutiric acid reactive substances (TBARS). Plasma cholesterol concentration was analyzed by a kinetic enzymatic method. Erythrocyte superoxide dismutase (CuZn SOD), glutathione peroxidase (GSH Px) and glutathione (GSH) levels were determined spectrophotometrically. Cholesterol values were found to be significantly high (p < 0.001), TBARS (0.05 > p > 0.02) and GSH (p < 0.001) levels significantly low in aged rats in comparison with young rats. Hypercholesterolemic diet induced significant increases in GSH (p < 0.001) and CuZn SOD (p < 0.001) levels, whereas a significant decrease in GSH Px activity (0.05 > p > 0.02) was observed in aged rats. In young rats hypercholesterolemic diet caused a significant increase in both GSH and CuZnSOD levels. Our results indicate an imbalance between radical production and destruction in favour of prooxidant conditions in the young rats and the induction by hypercholesterolemic diet of the antioxidative response in erythrocytes.
