Monozygotic twins were previously regarded as "identical". By now an increasing number of case reports of monozygotic but discordant twins have been reported, and therefore discordance between monozygotic twins is being investigated intensively. We report a case of female preterm monozygotic twins who were discordant for fetal megacystis due to cloacal dysgenesis. Pregnancy was achieved after intracytoplasmatic sperm injection and transfer of 2 embryos. By the first trimester fetal megacystis with consecutive oligohydramnios and hypoplasia of the lungs was diagnosed...

Glioblastoma multiforme (GBM) continues to be the most frequently diagnosed and lethal primary brain tumor. Adjuvant chemo-radiotherapy remains the standard of care following surgical resection. In this study, using reverse phase protein arrays (RPPAs), we assessed the biological effects of radiation on signaling pathways to identify potential radiosensitizing molecular targets. We identified subsets of proteins with clearly concordant/discordant behavior between irradiated and non-irradiated GBM cells in vitro and in vivo...

BACKGROUND: Preclinical and clinical studies have reported that human epidermal growth factor receptor 2 (HER2) overexpression yields resistance to endocrine therapies. Here the prevalence and prognostic impact of HER2-positive circulating tumor cells (CTCs) were investigated retrospectively in metastatic breast cancer (MBC) patients with a HER2-negative primary tumor receiving endocrine therapy. Additionally, the prevalence and prognostic significance of HER2-positive CTCs were explored in a chemotherapy cohort, as well as the prognostic impact of the estrogen receptor (ER) CTC status in both cohorts...

INTRODUCTION: This study explored schizotypy as a familial liability marker for schizophrenia-spectrum disorders (SSD) by examining: 1) the aggregation of schizotypy in families with a SSD patient, 2) whether familial resemblance of schizotypy is associated with ridge dissociations (RD), another SSD liability marker, 3) whether schizotypy aggregation patterns influence patients' psychopathology. METHODS: The sample comprised 30 SSD patients and 82 healthy first-degree relatives...

Associations between long-term physical activity and cortical function and brain structure are poorly known. Our aim was to assess whether brain functional and/or structural modulation associated with long-term physical activity is detectable using a discordant monozygotic male twin pair design. Nine monozygotic male twin pairs were carefully selected for an intrapair difference in their leisure-time physical activity of at least three years duration (mean age 34 ± 1 years). We registered somatosensory mismatch response (SMMR) in EEG to electrical stimulation of fingers and whole brain MR images...

BACKGROUND: E. histolytica is among the common causes of acute gastroenteritis. The pathogenic species E. histolytica and the nonpathogenic species E. dispar cannot be morphologically differentiated, although correct identification of these protozoans is important for treatment and public health. In many laboratories, the screening of leukocytes, erythrocytes, amoebic cysts, trophozoites and parasite eggs is performed using Native-Lugol's iodine for pre-diagnosis. AIMS: In this study, we aimed to investigate the frequency of E...

Pena-Shokeir phenotype is a rare disorder. However, its etiology is incompletely understood. It may be familial or may be due to anoxic-ischemic etiology. Although rare, it can affect one twin in a monoamniotic pregnancy, most likely due to early cord entanglement.

Pre-existing heterogeneities present in cardiac tissue are essential for maintaining the normal electrical and mechanical functions of the heart. Exacerbation of such heterogeneities or the emergence of dynamic factors can produce repolarization alternans, which are beat-to-beat alternations in the action potential time course. Traditionally, this was explained by restitution, but additional factors, such as cardiac memory, calcium handling dynamics, refractory period restitution, and mechano-electric feedback, are increasingly recognized as the underlying causes...

INTRODUCTION: Of the two million new HIV infections in adults in 2014, 70% occurred in sub-Saharan Africa. Several African countries have already approved guidelines for pre-exposure prophylaxis (PrEP) for individuals at substantial risk of HIV as part of combination HIV prevention but key questions remain about how to identify and deliver PrEP to those at greatest need. Throughout the continent, individuals in sero-discordant relationships, and members of key populations (sex workers, men who have sex with men (MSM), transgender women and injection drug users) are likely to benefit from the availability of PrEP...

Circulating tumor DNA (ctDNA) analysis has the potential to allow non-invasive analysis of tumor mutations in advanced cancer. In this study we assessed the reproducibility of digital PCR (dPCR) assays of circulating tumor DNA in a cohort of patients with advanced breast cancer and assessed delayed plasma processing using cell free DNA preservative tubes. We recruited a cohort of 96 paired samples from 71 women with advanced breast cancer who had paired blood samples processed either immediately or delayed in preservative tubes with processing 48-72 hours after collection...

The prevalence and clinical implications of discordance between Xpert MTB/RIF assays and the AdvanSure TB/NTM real-time polymerase chain reaction (PCR) for bronchial washing specimens have not been studied in pulmonary TB (PTB) patients. The discordant proportion and its clinical impact were evaluated in 320 patients from the bronchoscopy registry whose bronchial washing specimens were tested simultaneously with Xpert MTB/RIF and the TB/NTM PCR assay for three years, and the accuracy of the assays, including the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), were studied...

OBJECTIVE: To characterize reasons for discordance between administrative data and registry data in the determination of postoperative infectious complications. BACKGROUND: Data regarding the occurrence of postoperative surgical complications are identified through either administrative or registry data. Rates of complications vary significantly between these two types of data; the reasons for this are not well-understood. METHODS: The occurrence of 30-day inpatient infectious complications (pneumonia, sepsis, surgical site infection, and urinary tract infection) was compared between the NSQIP and administrative mechanisms at 4 academic hospitals between 2012 and 2014...

OBJECTIVE: The objective of the present study is to determine whether a predictive rule could safely reduce the number of negative blood cultures collected in an Australian ED and to assess the clinical impact of positive results from blood cultures taken in the ED. METHODS: All positive blood cultures taken in the ED at a single facility were retrospectively identified for the calendar year 2012. Clinically significant bacteraemia episodes were assessed against a predictive rule using major and minor clinical and laboratory criteria gathered from medical records and pathology databases, and compared with a randomly generated sample of ED patient episode with negative blood cultures...

An accurate diagnosis of metastases to the ovary is essential for adequate patient management. The aim of this retrospective study was to characterize clinicopathological features of metastatic malignancies that presented as an ovarian mass and compare them with their corresponding primary tumors. We reviewed clinical files and histological material of 120 patients with metastases to the ovary, diagnosed in our center between 2000 and 2014. Metastases were diagnosed before (18 %), synchronously (33 %), or after (49 %) the primary tumor was identified; 25 % were single, 40 % were unilateral; 47 % were ≥13 cm...

Purpose: There is inconclusive evidence to suggest the expression of programmed cell death (PD) ligand 1 (PD-L1) is a putative predictor of response to PD-1/PD-L1-targeted therapies in lung cancer. We evaluated the heterogeneity in the expression of PD-1 ligands in isogeneic primary and metastatic LC specimens. Experimental Design: From 12,580 post mortem cases, we identified 214 patients with untreated metastatic LC, of which 98 had adequately preserved tissues to construct a syngeneic primary LC/metastasis tissue microarray...

BACKGROUND: Integration of family planning services (FPS) into human immunodeficiency virus (HIV) care for HIV-infected women is an important aspect of the global prevention of mother-to-child transmission (PMTCT) strategy. We assessed the integration of FPS into routine care of HIV-infected mothers by evaluating the uptake and barriers of contraception and PMTCT services. METHODS: We conducted an interventional study using the interrupted time series approach in the health care facilities located in Yaounde, Cameroon...

BACKGROUND: Patients attending hospital emergency departments (ED) commonly cite the urgency and severity of their condition as the main reason for choosing the ED. However, the patients' perception of urgency and severity may be different to the nurses' perception of their urgency and severity, which is underpinned by their professional experience, knowledge, training and skills. This discordance may be a cause of patient dissatisfaction. The purpose of this study is to understand the extent of agreement/disagreement between the patient's perceived priority and actual triage category and associated factors...

OBJECTIVE: Adrenal vein sampling (AVS) is vital for determining treatment options for primary aldosteronism (PA), but is a difficult procedure. Adrenocorticotropic hormone (ACTH) infusion or bolus has been reported to improve AVS success rates by increasing cortisol secretion, but effects on aldosterone and thus lateralisation are controversial. We therefore aimed to determine the effects of ACTH on AVS in regard to success rates and lateralization. DESIGN AND METHOD: AVS was performed in the morning after overnight recumbency in patients with PA confirmed by fludrocortisone suppression testing...

Tumor heterogeneity has been shown for several cancers including breast cancer (BC). Despite the fact that expression of tumor markers may change throughout the metastatic process, rebiopsies at the time of recurrence are still not performed routinely at all institutions. The aims of the study were to evaluate changes in biomarker profiles during the metastatic process and to investigate whether previous anthracycline or endocrine therapy given in the adjuvant setting could affect the biomarker profile in metastatic lesions...
