BACKGROUND: Flow cytometry (FC) is a reliable tool for diagnosing and monitoring of plasma cell myeloma (PCM). Recent studies used FC for quantifying plasma cells (PCs) in peripheral blood (PB) using various panels, and an adverse prognostic effect of circulating PCs (cPCs) has been reported. We investigated the prognostic implication of cPCs quantified using a simple panel in patients with PCM. METHODS: Bone marrow (BM) and PB of 85 patients with PCM were analyzed by five-color FC at time of diagnosis...

We assessed the incidence and prevalence of hepatitis B (Hep B) in patients with or without diabetes mellitus using the UK Clinical Practice Research Datalink. This was a retrospective, observational study of diabetic and non-diabetic cohorts aged 0-80 years using Clinical Practice Research Datalink (NCT02324218). Incidence rates (IR) for each cohort were calculated. Crude and adjusted (Poisson Regression) IR ratios (IRR) were estimated with 95% confidence intervals (CI) to compare the cohorts. Hep B prevalence stratified by age, and hospitalisation related to Hep B were also calculated...

Given the expanding market of plant food supplements (PFSs) not undergoing any pre-marketing authorization, the overall quality, safety and efficacy of PFSs were subjected to a critical examination. Although many high-quality PFSs exist on the legal market, quality concerns are in general justified. Besides economic adulteration, active ingredients dramatically differing from label claims and among products were reported in several studies. In addition, PFSs sold via the Internet may be intentionally adulterated with undeclared prescription drugs...

Radiation esophagitis (RE) is a common adverse event associated with radiotherapy for non-small cell lung cancer (NSCLC). While plasma cytokine levels have been correlated with other forms of radiation-induced toxicity, their association with RE has been less well studied. We analyzed data from 126 patients treated on 4 prospective clinical trials. Logistic regression models based on combinations of dosimetric factors [maximum dose to 2 cubic cm (D2cc) and generalized equivalent uniform dose (gEUD)], clinical variables, and pretreatment plasma levels of 30 cytokines were developed...

Age is not only the greatest risk factor for Alzheimer's disease (AD) but also a key modifier of disease presentation and progression. Here, we investigate how longitudinal atrophy patterns vary with age in mild cognitive impairment (MCI) and AD. Data comprised serial longitudinal 1.5-T magnetic resonance imaging scans from 153 AD, 339 MCI, and 191 control subjects. Voxel-wise maps of longitudinal volume change were obtained and aligned across subjects. Local volume change was then modeled in terms of diagnostic group and an interaction between group and age, adjusted for total intracranial volume, white-matter hyperintensity volume, and apolipoprotein E genotype...

There has been great attention on indoleamine-2,3-dioxygenase 1 (IDO1) around cancer immunotherapy because of its role in enabling cancers to evade the immune system. The most recent spurt of high potent IDO1 inhibitors has been driven by the solution of the increased crystal structures of inhibitors with IDO1. Though the structural information of the active site of IDO1 obtained from the crystals are quite similar, the structures of reported potent inhibitors are quite different. Besides, while thousands of bioactive small molecule inhibitors of IDO1 exist, to date, only five compounds have entered clinical trials...

BACKGROUND: In recent years there has been much emphasis on 'research waste' caused by poor question selection, insufficient attention to previous research results, and avoidable weakness in research design, conduct and analysis. Little attention has been paid to the effect of inadequate development of interventions before proceeding to a full clinical trial. OBJECTIVE: We therefore propose to enrich the development phase of the MRC Framework by adding crucial elements to improve the likelihood of success and enhance the fit with clinical practice METHODS: Based on existing intervention development guidance and synthesis, a comprehensive iterative intervention development approach is proposed...
