Development of molecularly imprinted polymers to block quorum sensing and inhibit bacterial biofilm formation.

Bacterial biofilms are responsible for most clinical infections and show increased antimicrobial resistance. In this study, molecularly imprinted polymers (MIPs) were developed to specifically capture prototypical quorum sensing autoinducers [i.e., N-(3-oxododecanoyl)-L-homoserine lactone (3-oxo-C12AHL)], interrupt quorum sensing, and subsequently inhibit biofilm formation of Pseudomonas aeruginosa, an important human nosocomial pathogen. The synthesis of MIPs was optimized by considering the amount and typ...

Implications of DSM-5 for the diagnosis of pediatric eating disorders.

The aim of the study was to compare the DSM-IV, DSM-5, and ICD-10 eating disorders (ED) nomenclatures to assess their value in the classification of pediatric eating disorders. We investigated the prevalence of the disorders in accordance with each system's diagnostic criteria, diagnostic concordance between the systems, and interrater reliability.

Mind the overlap: how system problems contribute to cognitive failure and diagnostic errors.

Background Traditionally, research has examined systems- and cognitive-based sources of diagnostic error as individual entities. However, half of all errors have origins in both domains. Methods We conducted a focused ethnography of inpatient physicians at two academic institutions to understand how systems-based problems contribute to cognitive errors in diagnosis. Medicine teams were observed on rounds and during post-round work after which interviews were conducted. Field notes related to the diagnostic ...

Reliability of DSM and empirically derived prototype diagnosis for mood, anxiety and personality disorders.

Prominent psychiatric diagnostic systems such as the DSM-IV and ICD-10 have shown low reliability in clinical practice. An alternative approach to classification of psychiatric disorders is prototype matching. In the current study, we examined reliability of assessing mood, anxiety and personality disorders using a multi-method multi informant approach. More specifically, we examined diagnosis made by treating clinician and independent expert clinical interviewer, using three different diagnostic systems (D...

Mortality of patients examined at a diagnostic centre: A matched cohort study.

'Diagnostic Centres' has been established to provide a diagnostic pathway for patients with non-specific, serious symptoms that could be cancer. As little is known about the prognosis, we aimed to 1) analyse mortality of patients examined at the diagnostic centre, stratified on diagnostic outcome (cancer, serious-non-malignant disease, or other/no diagnosis), and 2) compare mortality for cancer patients examined at the diagnostic centre with cancer patients diagnosed through other routes.

Do mental health professionals use diagnostic classifications the way we think they do? A global survey.

We report on a global survey of diagnosing mental health professionals, primarily psychiatrists, conducted as a part of the development of the ICD-11 mental and behavioural disorders classification. The survey assessed these professionals' use of various components of the ICD-10 and the DSM, their attitudes concerning the utility of these systems, and usage of "residual" (i.e., "other" or "unspecified") categories. In previous surveys, most mental health professionals reported they often use a formal classi...

Differentiating vacuum-assisted breast biopsy from core needle biopsy: Is it necessary?

Needle biopsy has replaced excisional biopsy as a definitive diagnostic technique for breast tumours, although excisional biopsy is still used for complete tumour removal for therapeutic and/or diagnostic purposes. Many vacuum-assisted breast biopsy (VAB) systems have been made available by several manufacturers since the release of the Mammotome (MMT) by Johnson & Johnson in 1995. Several recent discussions have been conducted to identify whether core needle biopsy (CNB) or VAB, is more appropriate. Howeve...

Complex regional pain syndrome.

Complex regional pain syndrome (CRPS) is not a very common yet typical complication of extremity trauma in the daily practice of a trauma surgeon. The pathophysiology of this puzzling disease is still not completely understood and its impact on the patient cannot be overestimated. However, advantages have been made in diagnostics and therapy. While a multitude of different diagnostic systems has led to confusion in the past, we now have an internationally accepted, validated and easy to reproduce diagnostic...

Diagnostic heuristics in dermatology, Part 2: Metacognition and other fixes.

Diagnostic errors are the most common, costly and dangerous of medical mistakes. In part 1 of this series, we described how general and dermatology-specific cognitive and perceptual biases underlie most of our correct diagnoses, as well as being a source of diagnostic medical errors. In this second part of the series, we describe some tactics to combat diagnostic error. Metacognition, or thinking about how we think, is the central approach advocated to avoid errors of "uncritical" diagnostic thinking. Cur...

Diagnostic tests for autism spectrum disorder (ASD) in preschool children.

Autism spectrum disorder (ASD) is a behaviourally diagnosed condition. It is defined by impairments in social communication or the presence of restricted or repetitive behaviours, or both. Diagnosis is made according to existing classification systems. In recent years, especially following publication of the Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5; APA 2013), children are given the diagnosis of ASD, rather than subclassifications of the spectrum such as autistic disorder...

Diagnostic biomarkers for Parkinson's disease at a glance: where are we?

Parkinson's disease (PD) is a neurodegenerative disorder whose aetiology remains unclear: degeneration involves several neurotransmission systems, resulting in a heterogeneous disease characterized by motor and non-motor symptoms. PD causes progressive disability that responds only to symptomatic therapies. Future advances include neuroprotective strategies for use in at-risk populations before the clinical onset of disease, hence the continuing need to identify reliable biomarkers that can facilitate the c...
