It is now widely recognized that the isolation of circulating tumor cells based on cell surface markers might be hindered by variability in their protein expression. Especially in pancreatic cancer, isolation based only on EpCAM expression has produced very diverse results. Methods that are independent of surface markers and therefore independent of phenotypical changes in the circulating cells might increase CTC recovery also in pancreatic cancer. We compared an EpCAM-dependent (IsoFlux) and a size-dependent (automated Siemens Healthineers filtration device) isolation method for the enrichment of pancreatic cancer CTCs...

Purpose: Papillary thyroid carcinoma (PTC) is the most frequent endocrine tumor. BRAF(V600E) represents the PTC hallmark and is targeted with selective inhibitors (e.g. vemurafenib). Although there have been promising results in clinical trials using these inhibitors, most patients develop resistance and progress. Tumor clonal diversity is proposed as one mechanism underlying drug resistance. Here we have investigated mechanisms of primary and secondary resistance to vemurafenib in BRAF(WT/V600E)-positive PTC patient-derived cells with P16(-/-) (CDKN2A(-/-))...

Involving patients and the public in healthcare decision-making is on the policy agenda in several countries. The aim of our study was to describe and analyse the development of patient and public involvement from a policy perspective. We argue that the language of health policies can influence both the aims and the development of involvement methods. In this study health policy documents, which have guided the development of patient and public involvement in Finland have been analysed using methods of Membership Categorisation Analysis...

The sheer diversity of HLA alleles makes the probability of finding matched unrelated donors for patients requiring hematopoietic cell transplantation (HCT) a complex situation. New evidence suggests that mismatching at certain HLA loci may provide a greater benefit in terms of graft-versus-leukemia effect than other mismatches when HLA-matched donors are not available. This review summarizes the current understanding of HLA matching requirements for unrelated donor HCT.

BACKGROUND: The increasing interest on the impact of the gut microbiota on health and disease has resulted in multiple human microbiome-related studies emerging. However, multiple sampling methods are being used, making cross-comparison of results difficult. To avoid additional clinic visits and increase patient recruitment to these studies, there is the potential to utilize at-home stool sampling. The aim of this pilot study was to compare simple self-sampling collection and storage methods...

Nanomedicine, which is an application of nanotechnologies in healthcare is developed to improve the treatments and lives of patients suffering from a range of disorders and to increase the successes of drug candidates. Within the nanotechnology universe, the remarkable unique and tunable properties of dendrimers have made them promising tools for diverse biomedical applications such as drug delivery, gene therapy and diagnostic. Up-to-date, very few dendrimers has yet gained regulatory approval for systemic administration, why? In this critical review, we briefly focus on the list of desired basic dendrimer requirements for decision-making purpose by the scientists (go/no-go decision), in early development stages, to become clinical candidates, and to move towards Investigational New Drugs (IND) application submission...

PKU is a prevalent type of inherited metabolic disease, caused by the defective phenylalanine metabolism. In most PKU cases, mutations in the PAH gene could be found. Dysfunction of this hepatic enzyme will lead to diverse clinical symptoms due to a failure in converting phenylalanine into tyrosine. Here, we report an integration-free human induced pluripotent stem cell line (NJMUi001-A) generated from peripheral blood mononuclear cells of a PKU patient by using Sendai virus. This iPS cell line has characteristics of pluripotent stem cells and can be used as a useful tool for the investigation of this inherited metabolic disease...

Myocardial inflammation in autoimmune rheumatic diseases (ARDs) is the endpoint of various pathophysiologic processes. The Lake Louise-criteria is the most popular approach for the diagnosis of myocarditis. However, due to the diversity of myocardial inflammation in ARDs, some issues should be acknowledged. Of the three Lake Louise indices, early and late gadolinium enhancement (EGE and LGE respectively) measurements may be affected by co-existing disease processes or be present due to a fibrotic ARD like systemic sclerosis, leaving T2-ratio as the only uniformly robust measurement across ARDs...

Cancer is a heterogeneous disease harboring diverse subclonal populations that can be discriminated by their DNA mutations. Environmental pressure selects subclones that ultimately drive disease progression and tumor relapse. Circulating cell-free DNA (ccfDNA) can be used to approximate the mutational makeup of cancer lesions and can serve as a marker for monitoring disease progression at the molecular level without the need for invasively acquired samples from primary or metastatic lesions. This potential for molecular analysis makes ccfDNA attractive for the study of clonal evolution and for uncovering emerging therapeutic resistance or sensitivity...

Social media utilizes specific media platforms to allow increased interactivity between participants. These platforms serve diverse groups and purposes including participation from patients, family caregivers, research scientists, physicians, and pharmaceutical companies. Utilization of these information outlets has increased with integration at conferences and between conferences with the use of hashtags and "chats". In the realm of the "e-Patient" it is key to not underestimate your audience. Highly technical information is just as useful as a basic post...

Primary Familial Brain Calcification (PFBC) is a rare calcifying disorder of the brain with autosomal dominant inheritance, of unknown prevalence. Four causal genes have been identified so far: SLC20A2, PDGFB, PDGFRB, and XPR1, with pathogenic, probably pathogenic or missense variants of unknown significance found in 27.7% probands in the French PFBC series. Estimating PFBC prevalence from a clinical input is arduous due to a large diversity of symptoms and ages of onset and to incomplete clinical penetrance...

Psychometric investigations of the Eating Disorder Examination-Questionnaire (EDE-Q) have generally not supported the original scale structure. The present study tested an alternative brief factor structure in two large Portuguese samples: (1) a non-clinical sample of N = 4117 female students and (2) a treatment-seeking sample of N = 609 patients diagnosed with eating disorders. Confirmatory factor analysis revealed a poor fit for the original EDE-Q structure in both the non-clinical and the clinical samples but revealed a good fit for the alternative 7-item 3-factor structure (dietary restraint, shape/weight overvaluation and body dissatisfaction)...

The gastrointestinal tract comprises diverse functions. Despite recent developments in technology and science, there is no single and universal tool to monitor GI function in intensive care unit (ICU) patients. Clinical evaluation is complex and has a low sensitivity to diagnose pathological processes in the abdomen. We performed a MEDLINE and Pubmed search connecting abdominal assessment and critical care. Based on these findings we defined the following major categories of monitoring and diagnostic measures: clinical investigation; assessment of motility and digestive function; microbiome monitoring; perfusion monitoring; laboratory biomarkers and hormonal function; intra-abdominal pressure measurement; and imaging techniques...
