EEG arousals were quantified in 40 nocturnal polysomnographic recordings belonging to four age groups (teenagers: 10 to 19 years; young adults: 20 to 39 years; middle-aged: 40 to 59 years; elderly: > or = 60 years). Ten subjects (five males and five females) participated in each group. The subjects were healthy and sound sleepers. All sleep recordings were preceded by an adaptation night which ...

PURPOSE To determine the influence of age and gender on macular sensitivity to light in healthy subjects of 4 age groups using the MP-1 microperimeter. METHODS A prospective study was carried out on 50 healthy subjects (age range: 18-60 years) divided into 4 age groups; 18-30 years, 31-40 years, 41-50 years and 51-60 years. Full-threshold microperimetry of the central 10° of retina was perfor...

OBJECTIVES To examine attitudes, experiences, and preferences regarding advance directives (ADs) among adults of all ages. STUDY DESIGN Subjects were surveyed regarding end-of-life (EOL) care wishes. The survey included items measuring knowledge, experiences, and attitudes regarding ADs, as well as preferences toward initiation of discussions. METHODS Subjects included a random sample of pa...

Twenty four young (mean age 29.2 years, range 25-35) and 21 elderly (mean age 66.5, range 60-80) healthy subjects collected their urine in timed aliquots over 24 hours. The elderly subjects had been selected for their fitness by clinical and laboratory examinations and all lived independently at home. Sodium and potassium excretions were reduced in the elderly subjects compared with the young s...

OBJECTIVES To evaluate the association of serum γ-glutamyltransferase (GGT) levels with heart failure (HF) risk in the Finnish population. DESIGN Prospective population-based cohort study. SETTING The present study, which is a part of FINRISK study, was carried out in Finland. Subject study cohorts included 18 353 Finnish men and 19 726 women who were 25-74 years of age and free of HF at ba...

The Jebsen Test of Hand Function is used to assess a broad range of hand functions required for activities of daily living. The time needed to complete a variety of subtests is measured, with high scores indicative of abnormality. Normative values have been established for men and women in two age groups: 20 to 59 years and 60 to 94 years. The purpose of this study was to determine whether hand...

OBJECTIVE Acute kidney injury (AKI) is a highly morbid condition in critically ill patients that is associated with high mortality. Previous clinical studies have demonstrated the safety and efficacy of the Selective Cytopheretic Device (SCD) in the treatment of AKI requiring continuous renal replacement therapy in the intensive care unit (ICU). DESIGN, SETTING, PATIENTS A randomized, control...

Using signal processing measures we evaluate the effect of aging on the peripheral cardiovascular system. Laser Doppler flowmetry (LDF) signals, reflecting the microvascular perfusion, are recorded on the forearm of 27 healthy subjects between 20-30, 40-50, or 60-70 years old. Wavelet-based representations, Hölder exponents, and sample entropy values are computed for each time series. The resul...

BACKGROUND Studies based on laboratory data about thyroid stimulating hormone (TSH) and free thyroxine (FT4) reference interval (RI) show conflicting results regarding the importance of using specific values by age groups with advancing age. Retrospective laboratory data or non-specific criteria in the selection of subjects to be studied may be factors leading to no clear conclusions. The aim o...

Results 32 (%60) of the 53 patients included into this study were male. The average age of the patients was 49 ± 19 years. The hematological diagnosis of the patients were as follows; 19 were AML, 12 were MM, 7 were Non-Hodgin Lymphoma and 6were ALL. The most common reasons for ICU admissions were respiratory failure (%57) and septic shock (%17). The mean time delay starting from deteriation to...
