Background: While tumor-tissue remains the 'gold standard' for genetic analysis in cancer patients, it is challenged with the advent of circulating cell-free tumor DNA (ctDNA) analysis from blood samples. Here, we broaden our previous study on the clinical validation of plasma DNA in metastatic colorectal cancer patients, by evaluating its clinical utility under standard management care. Patients and methods: Concordance and data turnaround-time of ctDNA when compared with tumor-tissue analysis were studied in a real-time blinded prospective multicenter clinical study (n = 140 metastatic colorectal patients)...

Many studies have described an inverse relationship between birth weight and blood pressure (BP). Debate continues, however, over the magnitude and validity of the association. This analysis draws on the Early Determinants of Adult Health study (2005-2008), a cohort of 393 US adults (mean age 43 years; 47% male), including 114 same-sex sibling pairs deliberately sampled to be discordant on sex-specific birth weight for gestational age (BW/GA) in order to minimize confounding in studies of fetal growth and midlife health outcomes...

A case of monochorionic-monoamniotic (MCMA) twin pregnancy with growth discordance because of difference of cord diameter in forked umbilical cord is reported.MCMA twins were diagnosed at 12 weeks of gestation and twin growth discordance was considered during the follow-up twice-weekly visits to the ultrasound and prenatal care units. The pregnancy was terminated at 34 weeks. Two live female babies weighing 2510 g and 1940 g were delivered. Examination of placenta and umbilical cords after birth showed that the 2 cords merged into a conjoint cord 1 cm from insertion to the placenta (forked umbilical cord)...

Discordance in estrogen receptor alpha (ERα), progesterone receptor (PR), androgen receptor (AR) and human epidermal growth factor receptor 2 (HER2) status between primary breast cancers and solid distant metastases ("conversion") has been reported previously. Even though metastatic spread to the peritoneal and pleural cavities occurs frequently and is associated with high mortality, the rate of receptor conversion and the prognostic implications thereof remain elusive. We therefore determined receptor conversion in 91 effusion metastases (78 pleural, 13 peritoneal effusions) of 69 patients by immunohistochemistry (IHC) and in situ hybridization...

AIM: To investigate the clinicopathological variables in early gastric cancer (EGC) patients in relation to differentiation discrepancy. METHODS: The data of 265 specimens from 240 patients with EGC, who had undergone radical operation at Hallym University Sacred Heart Hospital from 2010 to 2015, were retrospectively analyzed. We evaluated clinical, endoscopic, and histopathological data according to histological discrepancy. RESULTS: Clinically significant discrepancy rate showed the difference in differentiated type (well and moderately differentiated) and undifferentiated type (poorly differentiated and signet ring cell) between endoscopic biopsies and postoperative specimens was 9...

OBJECTIVE: To evaluate if presence of extreme maternal serum biochemical analytes recurs in consecutive pregnancies. We hypothesized that presence of >1 extreme analyte in prior pregnancy is associated with increased risk of adverse pregnancy outcome in subsequent pregnancy. METHODS: Retrospective cohort study of singleton pregnancies evaluated and delivered in 2 consecutive pregnancies (2011-2015). Adverse outcomes were defined as indicated preterm delivery before 37 completed weeks due to preeclampsia, fetal growth restriction or other complications...

Emotions important for survival and social interaction have received wide and deep investigations. The application of the fMRI technique into emotion processing has obtained overwhelming achievements with respect to the localization of emotion processes. The ERP method, which possesses highly temporal resolution compared to fMRI, can be employed to investigate the time course of emotion processing. The emotional modulation of the ERP component has been verified across numerous researches. Emotions, described as dynamically developing along with the growing age, have the possibility to be enhanced through learning (or training) or to be damaged due to disturbances in growth, which is underlain by the neural plasticity of emotion-relevant nervous systems...

BACKGROUND: Advancing knowledge in molecular pathogenesis of hepatocellular carcinoma (HCC) opens up new horizons in the diagnostic, prognostic and therapeutic perspectives. Assessing the expression of molecular targets prior to definitive treatment is gaining importance in clinical practice. In this study, we investigated the variation in expression pattern of stemness markers in synchronous multi-focal HCC. METHODS: In the first cohort, 21 liver explants with multi-focal HCC were examined for expression of stemness markers EpCAM, Sox9 and CK19 by immunohistochemistry (IHC)...

BACKGROUND: Conservative wait-and-scan management for vestibular schwannomas (VSs) is an important treatment option, but its role is unclear because of discordance between tumor growth and hearing outcomes. METHODS: The present study was a retrospective analysis of 97 patients with sporadic VSs who were followed-up without treatment between 2003 and 2012. Tumor volume was measured by three-dimensional volumetry at each follow-up visit. The median follow-up duration was 47 months (range, 13-122 months)...

Fetal malformations are more frequent in twins than in singletons. The aim of our study was to define the influence of a malformed twin on di-chorionic pregnancy outcomes. We performed a retrospective cohort study of di-chorionic pregnancies delivered between 2000 and 2015. Exclusion criteria were: both twins affected by fetal malformations, double intra-uterine fetal death in pregnancies without fetal malformation, selective feticide and therapeutic pregnancy termination. We compared maternal and fetal outcomes of di-chorionic pregnancies not complicated by fetal malformations with pregnancies affected by a single malformed fetus with conservative management...

Massive perivillous fibrinoid deposition (MFD) and maternal floor infarction (MFI) are lesions of unknown etiology associated with poor perinatal outcomes, including fetal intrauterine growth restriction and neurodevelopmental injury, high risks of pregnancy loss, and recurrence in subsequent gestations. MFI comprises massive intervillous fibrinoid deposition concentrated at the maternal floor. MFD is a similar lesion but is diffuse within the parenchyma. MFD/MFI lesions represent a spectrum of severity of cloak-like perivillous fibrinoid deposition, and there is mounting evidence that, often, they represent sequelae of immune-mediated phenomena and/or an imbalance in factors that normally maintain the fluidity of blood in the maternal space...

BACKGROUND: Solitary fibrous tumor is an uncommon soft tissue neoplasm with intermediate biological behavior, which rarely metastasizes. Malignant solitary fibrous tumor, although not clearly defined, is rarely described in the prostate. The present case is characterized by some peculiarities if compared with previously reported cases of prostatic malignant solitary fibrous tumor. Firstly, it does not show a homogeneous morphology: part of the neoplasm (about 50%) showed the features of a conventional solitary fibrous tumor, while the remaining part showed the features of a malignant solitary fibrous tumor...

OBJECTIVE: Exposure to adverse social environments has been associated with psychotic and depressive symptoms in adolescence in cross-sectional studies, but the longitudinal relation is unclear. This study examined whether longitudinal trajectories of exposure to adverse social environments across childhood are associated with psychotic experiences and depressive symptoms in adolescence. METHOD: Data on participants from the Avon Longitudinal Study of Parents and Children (ALSPAC) were used to estimate longitudinal trajectories of childhood exposure to neighborhood cohesion (NC), discord (ND), and stress (NS) using latent class growth modeling...

Molecular tests to detect the presence of Mycobacterium tuberculosis and genetic polymorphisms in the rpoB gene conferring resistance to rifampicin (RMP) have become integral parts of tuberculosis diagnostics worldwide. These assays are often performed sequentially or in parallel to phenotypic drug susceptibility testing. Discordances between molecular and phenotypic tests invariably occur. Root causes range from pre-, post- and analytic errors to co-existence of non-tuberculous mycobacteria, silent mutations, mutations outside the 81 base-pair RMP resistance-determining region, non-canonical mutations conferring increased minimal inhibitory concentrations below the critical concentration in some phenotypic drug susceptibility tests, and heteroresistance...

Plant morphogenesis requires differential and often asymmetric growth. A key role in controlling anisotropic expansion of individual cells is played by the cortical microtubule array. Although highly organized, the array can nevertheless rapidly change in response to internal and external cues. Experiments have identified the microtubule-severing enzyme katanin as a central player in controlling the organizational state of the array. Katanin action is required both for normal alignment and the adaptation of array orientation to mechanical, environmental, and developmental stimuli...

OBJECTIVE: Our purpose was to examine the association between discordant growth and perinatal mortality and morbidity among twins with careful adjustment for maternal confounding factors. STUDY DESIGN: Two cohorts with and without chorionicity data were compared using generalized estimating modeling. RESULTS: Our population-based dataset consisted of 12,656 individual twins from whom 4% (452/12,656) had≥30% growth discordance. A subgroup of this population with chorionicity information had an incidence of 7...

BACKGROUND: Invasive lobular carcinoma (ILC) is characterized by an infiltrative discohesive growth pattern, making it difficult to accurately assess both clinically and by imaging studies. Despite favourable biological characteristics, challenges remain in the surgical treatment of ILC. We aimed to evaluate radiology/histology concordance and identify histological and biological parameters on core biopsies that may predict final tumour histology and guide surgical treatment decisions...
