We prospectively studied 298 patients with cystic fibrosis (mean age 11.3 years; range 2 months to 32 years; sex ratio, 0.47) for nontuberculous mycobacteria in respiratory samples from January 1, 1996, to December 31, 1999. Mycobacterium abscessus was by far the most prevalent nontuberculous mycobacterium: 15 patients (6 male, 9 female; mean age 11.9 years; range 2.5-22 years) had at least one...

OBJECTIVE Use axial magnetic resonance imaging to test the null hypothesis that no difference exists in apparent vaginal thickness between women with and those without prolapse. METHODS Magnetic resonance imaging studies of 24 patients with prolapse at least 2 cm beyond the introitus were selected from an ongoing study comparing women with prolapse with normal control subjects. The magnetic r...

BACKGROUND To ensure that potential kidney donors have no renal impairment, it is extremely important to have accurate methods for evaluating the glomerular filtration rate (GFR). The golden standard, clearance of inulin, has been used in the present study. The aim was to evaluate the effects of age and sex on renal function and present reference data. METHODS A total of 122 potential kidney ...

W e comment on a recent study by Dehghan et al. (1), who identified high serum uric acid as an independent risk factor for type 2 diabetes in adults. We investigated serum levels of uric acid in a large cohort of obese adolescents (n 355; mean SD age 13.1 4.1 years and age range 10–22 years) and normal-weight control subjects (n 200) of similar age and sex distribution (2). Uric acid levels wer...

In study 1 (n = 51, M age = 21.4 years, SD = 5.7), the validity of the Portuguese adaptation of the Gudjonsson Suggestibility Scales (Pires, 2011) was shown through the comparison of means of the original (Gudjonsson, 1997) and the translated scales and the analysis of the correlations between the GSS1 and GSS2 scores. The relationships between interrogative suggestibility and the big five were...

OBJECTIVE There is some evidence that people born with high birth weight may be at increased risk of cardiovascular disease in adulthood. Details of the underlying mechanisms remain unknown. We sought to determine whether people born large for gestational age have poor arterial health, increased adiposity, and a poor cardiovascular risk factor profile. APPROACH AND RESULTS Carotid intima-medi...

This study examined factors related to word list performance predictions made by younger and older adults. A performance prediction is an estimate made prior to being exposed to the material that is studied for a specific task. The current study examined the age differences in a sample of 59 older adults (M = 76.83 years old, SD = 8.28) and 51 younger adults (M = 21.19 years old, SD = 3.22) on ...

Cannabis is the most frequently used illicit drug worldwide. Cross-sectional neuroimaging studies suggest that chronic cannabis exposure and the development of cannabis use disorders may affect brain morphology. However, cross-sectional studies cannot make a conclusive distinction between cause and consequence and longitudinal neuroimaging studies are lacking. In this prospective study we inves...
