Early death is the main obstacle for the cure of patients with acute promyelocytic leukemia (APL). We have analyzed risk factors of early death from 526 consecutive newly diagnosed APL patients between 2004 and 2016. The overall incidence of early death was 7.2% (38/526). The peak hazard of early death occurred in the first 0-3 days. Multivariate logistic analysis demonstrated white blood cell (WBC) counts [odds ratio (OR) = 1.039; 95% confidence interval (CI): 1.024-1.055; P < 0.001], age (OR = 1...

The nanopathological diagnostics (ND) is an ultra-specialized branch of pathological anatomy aimed to identify the nanoparticles of metallic, semimetallic, or nonmetallic elements in the inorganic particulate matter present inside pathological tissues, even on the nanometer scale. ND exploits an environmental scanning electron microscope, connected to an X-ray microprobe mounted on an energy-dispersive spectrometer. The searching of nanoparticles can be performed on paraffin-embedded material, omitting emissions of black overlay and plating procedures...

AIM: Diagnosing individuals at ultra high risk (UHR) for psychosis can improve early access to treatment, and a two-stage model utilizing self-report screening followed by a clinical interview can be accurate and efficient. However, it is currently unclear which screening cut-offs to adopt with different populations. METHODS: A systematic review of diagnostic accuracy studies evaluating the Prodromal Questionnaire (PQ) as a preliminary screener for UHR and psychosis was conducted to examine screening effectiveness in different contexts...

Colorectal cancer (CRC) is a leading cause of cancer mortality. Diet has a significant influence on colon cancer risk. Identifying chemopreventive agents, dietary constituents, practices and/or diet supplements that promote gut health and reduce the incidence of intestinal neoplasias and CRC could significantly impact public health. Sphingadienes (SDs) are dietary sphingolipids found in plant-based food products. SDs are cytotoxic to colon cancer cells and exhibit chemopreventive properties. The aim of the present study was to develop a sensitive and robust ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method for quantifying SDs in food products and biological samples...

INTRODUCTION: Psychosis and mania share conceptual, genetic and clinical features, which suggest the possibility that they have common antecedents. Participants identified to be at-risk for psychosis might also be at-risk for mania. We aimed to identify the rate and predictors of transition to mania in a cohort of youth with clinical or familial risk for psychosis. METHODS: Among a cohort of 416 young people with an at-risk mental state for psychosis defined using the Ultra-High-Risk (UHR) criteria, 74...

Neurological soft signs (NSS) are one of the biomarkers for schizophrenia spectrum disorders. However, a few studies have examined the prevalence of NSS across the schizophrenia spectrum. The present study adopted a quasi-longitudinal study design and examined the prevalence of NSS and their associations with clinical and behavioural manifestations in participants in different stages of the illness. The abridged version of the Cambridge Neurological Inventory was administered to 39 patients with the first-episode schizophrenia, 39 individuals with ultra-high risk (UHR) for psychosis, 39 individuals with schizotypy, and 39 healthy controls...

BACKGROUND: Delayed cerebral ischemia following aneurysmal subarachnoid hemorrhage is characterized by a highly complex pathophysiology and results in neurological deterioration after the inciting bleed. Despite its significant consequences, prompt diagnosis can be elusive and treatment is often administered too late. Early brain injury, which occurs within the first 72 hours post-ictus, may be an important factor for delayed cerebral ischemia and poor overall outcome. Here we explore the purported clinical and pathological manifestations of early brain injury to identify biomarkers that could have prognostic value...

BACKGROUND: Plasma high triacylglycerols and low HDL-C concentration are associated with increased cardiovascular events. Extended-release nicotinic acid (ERN) was shown to reduce plasma triacylglycerols and total cholesterol but also to markedly increase high-density lipoprotein-cholesterol (HDL-C). No data on the effect of ERN on different species of triacylglycerol, cholesteryl ester, and phospholipids are available. In this study, we applied a nontargeted lipidomic approach to investigate the plasma and lipoproteins lipids profile of hypertriglyceridemic patients treated with ERN or a placebo in order to identify new lipids markers associated with this treatment...

BACKGROUND: Longitudinal research into early intervention for youth at ultra high risk (UHR) for psychosis demonstrates beneficial outcomes including increased treatment compliance and greater participation in education and the workforce. Despite known barriers for rural youth accessing mental health services, research comparing urban and rural UHR youth is lacking. The study included an examination of the impact of substance use on functioning of UHR youth. METHODS: Youth aged 12 to 25 years were recruited from the urban area of Newcastle or the rural area of Orange, New South Wales, Australia, and identified as UHR by the Comprehensive Assessment of At Risk Mental States...

The addition of off-the-shelf cognitive measures to established prodromal criteria has resulted in limited improvement in the prediction of conversion to psychosis. Tests that assess cognitive processes central to schizophrenia might better identify those at highest risk. The latent inhibition paradigm assesses a subject's tendency to ignore irrelevant stimuli, a process integral to healthy perceptual and cognitive function that has been hypothesized to be a key deficit underlying the development of schizophrenia...

BACKGROUND: The reason for declining risk to psychosis across individuals assessed and meeting Ultra High Risk (UHR) criteria is still unclear. No studies have investigated the potential substantial role of the underlying risk enrichment across all the individuals undergoing an UHR assessment. METHODS: Cohort study including all non-psychotic subjects who were assessed on suspicion of psychosis risk by the OASIS UHR service in the period 2001 to 2015. Posttest (after UHR assessment) and pretest risk (before UHR assessment) of psychosis were stratified and compared across three time periods (2001-2005, 2006-2010, 2011-2015) with Cox analysis and modulating factors were investigated...

Alzheimer's disease (AD) is the most common form of dementia. The development of assay technologies able to diagnose early-stage AD is important. Blood tests to detect biomarkers, such as amyloid and total Tau protein, are among the most promising diagnostic methods due to their low cost, low risk, and ease of operation. However, such biomarkers in blood occur at extremely low levels and are difficult to detect precisely. In the early 2000s, a highly sensitive assay technology, immunomagnetic reduction (IMR), was developed...
