BACKGROUND Twins, compared to singletons, have an increased risk of perinatal mortality and morbidity, due mainly to a higher prevalence of preterm birth and low birthweight. Intrauterine growth restriction (IUGR) is also common and can affect one or both fetuses. In some cases, however, one twin is much smaller than the other (growth discordance). Usually, high birthweight discordance is assoc...

BACKGROUND Diagnostic discordance for osteoporosis is the presence of different categories of T-scores in 2 skeletal sites of an individual patient, falling into 2 different diagnostic categories identified by the World Health Organization classification system. OBJECTIVES To evaluate the prevalence and risk factors for T-score discordance between spine and total hip measurement sites. METH...

This study aimed to evaluate the prevalence of birthweight discordance among twins, to determine the risk cut-off point for birthweight discordance, and to clarify whether perinatal deaths are aggravated by birthweight discordance or by low birthweight itself. A population-based analysis of all twins born between 1995 and 1999 in Japan was conducted using data collected from national birth, dea...

BACKGROUND Discordance between patients with rheumatoid arthritis (RA) and their rheumatology health care providers is a common and important problem. The objective of this study was to perform a comprehensive clinical evaluation of patient-provider discordance in RA. METHODS A cross-sectional observational study was conducted of consecutive RA patients in a regional practice with an absolute...

OBJECTIVES The degree of actual intertwin birth weight (BW) or ultrasound estimated fetal weight (EFW) discordance that justifies elective delivery is yet to be established. The main aim of this study was to ascertain the performance of BW and ultrasound EFW discordance in the prediction of perinatal loss in twin pregnancies. METHODS This was a retrospective study of all twin pregnancy births...

OBJECTIVE Evidence for the role of first-trimester ultrasound in predicting outcome in twin pregnancies is conflicting. The aim of this study was to determine the association between crown-rump length (CRL) discordance and adverse perinatal outcome in twin pregnancies. METHODS This was a retrospective study of all twin pregnancies of known chorionicity from a large regional cohort over a 10-y...

PURPOSE The aim of this study was to compare the hormone receptors' (HR) and HER2/neu status between core needle biopsy (CNB) and residual tumor after surgery of breast cancer treated with neoadjuvant chemotherapy (NAC), and also to evaluate the impact of discordance and other clinicopathological factors on survival. METHODS Oestrogen receptor (ER), progesterone receptor (PR) and HER2/neu sta...
