Iodine concentration and prevalence of thyroid disease in older people after salt iodization in Turkey.

Background: Iodine uptake is a main factor affecting thyroid disease. In Turkey, mandatory salt iodization began in 1999-2000.

Aims: This study in 2009 determined the prevalence of thyroid diseases in older people in Mamak district, Ankara after iodization to ascertain if salt iodization alone is sufficient to reach adequate iodine levels in the older population.

Evaluation of Cardiac Autonomic Functions in Older Parkinson's Disease Patients: a Cross-Sectional Study.

Sarcopenia prevalence and factors associated with sarcopenia in older people living in a nursing home in Ankara Turkey.

Aim: Sarcopenia is prevalent in older people, and is related to survival and disability. There are no data on sarcopenia evaluated according to European Working Group on Sarcopenia in Older People criteria for nursing home residents in Turkey. We aimed to evaluate the prevalence of sarcopenia according to European Working Group on Sarcopenia in Older People criteria and associated factors with sarcopenia among nursing home residents in Turkey.

The prevalence of anemia, iron, vitamin B12, and folic acid deficiencies in community dwelling elderly in Ankara, Turkey.

Objective: Anemia is a common problem among older people. Deficiency of essential erythropoiesis elements (iron, vitamin B12, and folic acid) is one of the major causes of anemia in older people. Studies evaluated prevalence of anemia in our country generally consisted of older people admitted to hospital.

Comparison of the C14 urea breath test and histopathology in the diagnosis of Helicobacter pylori in the elderly.

Objectives: To compare the sensitivity and specificity of C[14] urea breath test with histopathological findings in biopsies obtained through endoscopy.

Methods: In this cross-sectional study, conducted at the Medical Faculty Ankara University, Ankara, Turkey between January and October 2009, 100 patients aged 65 and above who fulfilled the criteria for inclusion were enrolled. Oesophago-gastroduodenoscopy was carried out on the patients after eight hours of fasting, using a Fujinon endoscope, by the same expert.

Plasma viscosity: is a biomarker for the differential diagnosis of Alzheimer's disease and vascular dementia?

In this study, the importance of plasma viscosity (PV) as a biomarker in differential diagnosis of dementia subtypes especially Alzheimer's disease (AD) and vascular dementia (VaD) was investigated. Our study recruited 45 patients with AD, 35 patients with VaD, and control participants. Individuals with inflammatory disease, infection, heart, liver, renal failure, and with high erythrocyte sedimentation rate and C-reactive protein levels were excluded from the study.

Comparison of different glomerular filtration methods in the elderly: which formula provides better estimates?

Objectives: Technetium-99m diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) is an ideal radioisotopic method having a high correlation with inulin clearance for the determination of glomerular filtration rate (GFR). Different formulas like creatinine clearance (CrCl) in 24 h urine samples, Cockroft-Gault formula (CGF), and modification of diet in renal disease (MDRD) are being used to come up with an estimate. In this study, we compared (99m)Tc-DTPA with the formulas mentioned above in an attempt to best identify the method that would yield the nearly ideal GFR estimates in the elderly.

The effect of age and Helicobacter pylori infection on gastric epithelial cell kinetics.

Background: Helicobacter pylori infection is a known risk factor for gastric cancer. The aim of the study was to determine the effect of H. pylori and age on gastric epithelial cell kinetics.

Effects of weight loss on ventricular systolic and diastolic functions and left ventricular mass assessed by tissue doppler imaging in obese geriatric women: preliminary report.

Background And Aims: Obesity is one of the most common diseases in the world. Particularly in elderly subjects, the effects of weight loss on cardiac functions have not been previously investigated by means of pulsed wave tissue doppler imaging (PWTDI). Using PWTDI, we examined the effects of weight loss on cardiac functions and left ventricular (LV) mass in obese geriatric women.

Effects of garlic consumption on plasma and erythrocyte antioxidant parameters in elderly subjects.

Background: The oxidative stress theory of aging is one of the most widely acknowledged theories of aging. The intake of fruits and vegetables with antioxidant power is associated with a reduced incidence of many chronic diseases of aging.

Objective: The effects of ingesting garlic on plasma and erythrocyte antioxidant parameters of elderly subjects were investigated in this study.

Effects of apple consumption on plasma and erythrocyte antioxidant parameters in elderly subjects.

The effects of apple consumption on plasma and erythrocyte antioxidant parameters of elderly subjects were investigated in this study. Fifteen elderly subjects (mean age 71.86 +/- 4.

Late onset rheumatoid arthritis: clinical and laboratory comparisons with younger onset patients.

We aimed to compare the clinical and laboratory profiles of the patients presenting late onset rheumatoid arthritis (LORA) with younger onset rheumatoid arthritis (YORA) patients. During the period between January 1995 and December 2004, 124 patients with LORA were identified from a retrospective chart review of inpatients and outpatients. They were compared with 150 YORA patients examined during the same period including their clinical and laboratory findings.

Thyroid disorders in hemodialysis patients in an iodine-deficient community.

There are various changes in the thyroid gland and its function in chronic renal failure (CRF). These changes include lower levels of circulating thyroid hormone, altered peripheral hormone metabolism, decreased binding to carrier proteins, possible reduction in tissue hormone content, and increased iodine storage in the thyroid gland. The decrease of excretion of urinary iodine in CRF increases serum inorganic iodine level and iodine content of the thyroid, which consequently enlarges the gland.

Oxidative stress and antioxidant status in elderly diabetes mellitus and glucose intolerance patients.

Increased oxidative stress and impaired anti-oxidant defense have been suggested as contributory factors for initiation and progression of complications in diabetes mellitus. Aging itself has been shown to be along with increased oxidative stress and lower anti-oxidant defense. We aimed at investigating oxidative stress and anti-oxidant enzymes in 61 elderly subjects.

General or disease specific questionnaire? A comparative study in hemodialysis patients.

Objective: Today questionnaires developed to assess important outcome measures such as health-related quality of life are widely used. In this study we evaluated the construct validity of the Nottingham Health Profile (NHP) and the reliability of its Turkish version in hemodialysis patients.

Methods: In a sample of patients on renal dialysis (n = 94) the quality of life is measured by the NHP.
