OBJECTIVE To evaluate bone mass accrual and determine the influence of clinical, anthropometric, dietary and biochemical parameters on bone mass. METHODS A cohort study including 35 prepubertal HIV-infected children, between 7 and 12 years, attended at a referral center. At time 1 (T1) and time 2 (T2), patients were assessed according to clinical, anthropometric, dietary, biochemical paramete...

OBJECTIVE To assess relationships between dietary intake at age 12, 18 and 36 months and BMI Z-scores at age 36 months in a bi-ethnic group. DESIGN A prospective cohort study comparing cross-sectional and longitudinal data. Exposures included dietary intake at 12, 18 and 36 months (FFQ) with an outcome of BMI Z-score at age 36 months. SETTING Born in Bradford 1000 study, Bradford, UK. SUB...

We have previously proposed BB94] a model for the generation of segmental durations which proceeds in two steps : (a) prediction of the timing of a salient acoustic event per syllable according to phonotactic and syntactic information, and (b) application of a repartition model which determines the duration of each individual segment between these events. This paper focusses on the repartition ...

1.1 Z-scores versus one-sample T-tests If we knew the mean, µ , and standard deviation, σ , of the control "population", we could construct the "Z-score": σ µ p Z − = where p is the single patient score, and determine the probability of obtaining a Z-score this large from the "Z-distribution" (or "normal" or "Gaussian" distribution). In practice, Z-scores are often tested this way when the grou...

Background: The primary objective of this study was to assess BMD change in Iranian females with breast cancer. Methods: A sample of 73 female breast cancer patients treated with adjuvant chemotherapy either alone or followed by radiotherapy between March 2013 and February 2016 were considered for this study. Bone mineral density (BMD) change was evaluated by measuring z-score of lumbar spin...

BACKGROUND Perfluoroalkyl substances (PFAS) may affect body mass index (BMI) and other components of cardiometabolic (CM) risk during childhood, but evidence is scarce and inconsistent. OBJECTIVES We estimated associations between prenatal PFAS exposures and outcomes relevant to cardiometabolic risk, including a composite CM-risk score. METHODS We measured perfluorohexanesulfonic acid (PFHx...

OBJECTIVE Genome-wide linkage analyses of schizophrenia have identified several regions that may harbor schizophrenia susceptibility genes, but given the complex etiology of the disorder, it is unlikely that all susceptibility regions have been detected. To address this issue, the authors ascertained 606 Han Chinese families comprising 1,234 affected members. METHOD Probands with schizophreni...

OBJECTIVE To examine the effectiveness of home visiting by paraprofessionals and by nurses as separate means of improving maternal and child health when both types of visitors are trained in a program model that has demonstrated effectiveness when delivered by nurses. METHODS A randomized, controlled trial was conducted in public- and private-care settings in Denver, Colorado. One thousand on...
