Douglas J Demetrick
Context Specimen misidentification is the most significant error in laboratory medicine, potentially accounting for hundreds of millions of dollars in extra health care expenses and significant morbidity in patient populations in the United States alone. New technology allows the unequivocal documentation of specimen misidentification or contamination; however, the value of this technology currently depends on suspicion of the specimen integrity by a pathologist or other health care worker. Objective To test the hypothesis that there is a detectable incidence of unsuspected tissue specimen misidentification among cases submitted for routine surgical pathology examination...

Background and aims Pain is a subjective experience, and as such, pre-clinical models of human pain are highly simplified representations of clinical features. These models are nevertheless critical for the delivery of novel analgesics for human pain, providing pharmacodynamic measurements of activity and, where possible, on-target confirmation of that activity. It has, however, been suggested that at least 50% of all pre-clinical data, independent of discipline, cannot be replicated. Additionally, the paucity of "negative" data in the public domain indicates a publication bias, and significantly impacts the interpretation of failed attempts to replicate published findings...

Cristiano Ialongo, Sergio Bernardini
There is a compelling need for quality tools that enable effective control of the extra-analytical phase. In this regard, Six Sigma seems to offer a valid methodological and conceptual opportunity, and in recent times, the International Federation of Clinical Chemistry and Laboratory Medicine has adopted it for indicating the performance requirements for non-analytical laboratory processes. However, the Six Sigma implies a distinction between short-term and long-term quality that is based on the dynamics of the processes...

BACKGROUND: Reporting on the presence of antimicrobial resistance is of considerable concern both for individual patient care and for understanding the underlying health status within the community at large. Antimicrobial resistance is solely dependent upon clinical laboratory detection and thus can be impacted upon by the quality and competence of medical laboratories. Proficiency testing or external quality assessment (PT/EQA) is the international standard for the direct measurement of medical laboratory performance on critical testing...

Morgan Meyer
Do-it-yourself (DIY) biology and medicine are based on various practices and logics: amateur and DIY practices, the ethics of hacking and open source, the drive to domesticate molecular biology and genetics, the ideal of participation and citizen science. The article shows that this democratization is a process that is at once spatial (construction of new spaces), technical (creative workarounds equipment), social (establishment of accessible networks/laboratories) and political. It is therefore through their practices, gestures and questions - tinkering, experimenting, working around, amaterializing, ethicizing, comparing, valuating, etc...

PURPOSE: Data sharing between clinicians, laboratories, and patients is essential for improvements in genomic medicine, but obtaining consent for individual-level data sharing is often hindered by a lack of time and resources. To address this issue, the Clinical Genome Resource (ClinGen) developed tools to facilitate consent, including a one-page consent form and online supplemental video with information on key topics, such as risks and benefits of data sharing. METHODS: To determine whether the consent form and video accurately conveyed key data sharing concepts, we surveyed 5,162 members of the general public...

REVIEW
Jaak Ph Janssens, Klaus Schuster, Andreas Voss
Preventive, predictive, and personalized medicine (PPPM) has created a wealth of new opportunities but added also new complexities and challenges. The European Cancer Prevention Organization already embraced unanimously molecular biology for primary and secondary prevention. The rapidly exploding genomic language and complexity of methods face oncologists with exponentially growing knowledge they need to assess and apply. Tissue specimen quality becomes one major concern. Some new innovative medicines cost beyond any reasonable threshold of financial support from patients, health care providers, and governments and risk sustainability for the health care system...

EDITORIAL
Samar Mahmood, Muqadus Tabraze
The issue of overprescribing laboratory investigations is an old one in the world of medical practice and it has unfortunately seen a tremendous increase with the digitalisation of medicine, in more recent times. Phrased usually as 'defensive medicine,' this kind of overmedicalisation steers medical practice away from the ethical, skill-refining fronts on the part of doctors and imposes an unnecessary financial burden on the patients' pockets, adding to their suffering. Pakistan has not been able to save itself either, from the impropriety that roots out of what is now almost a norm in medical practice...

Jason Peeler, Hugo Bergen, Alison Bulow
Medical schools have traditionally used a lecture and dissection-based approach for educating students about human anatomy. There is growing interest in the adoption of alternative teaching and learning activities (TLAs) that incorporate the use of cadaveric prosection and computer-based learning into musculoskeletal (MSK) anatomy curricula. The purpose of this investigation was to examine retrospectively how different TLAs influenced student perceptions about learning, and performance on MSK anatomy examinations...

Domenico Ribatti
Sir Mac Farlane Burnet was the most honored of all Australian scientists. In 1960, Burnet shared the Nobel Prize for Medicine with Peter Medawar of Britain for the discovery of acquired immunological tolerance, He developed techniques for growing influenza viruses in the chorioallantoic membrane of the chick embryo. This became standard laboratory practice. He continued to work with chick embryos long after the use of cell cultures had become general. His virology research resulted in significant discoveries concerning the nature and replication of viruses and their interaction with the immune system...

OBJECTIVE: Recently, the National Institutes of Health (NIH) redefined clinical trials to include any study involving behavioral or biomedical interventions. In line with a general framework from experimental medicine, we argue that it is crucial to distinguish between experimental laboratory studies aimed at revealing psychological mechanisms underlying behavior and randomized controlled trials (RCTs) in clinical samples aimed at testing the efficacy of an intervention. METHOD: As an illustration, we reviewed the current state of the evidence on the efficacy of cognitive bias modification (CBM) interventions in alcohol use disorders...

BACKGROUND: Acute aneurysmal subarachnoid hemorrhage (SAH) is a medical and neurosurgical emergency from ruptured brain aneurysm. Aneurysmal SAH is identified on brain computed tomography (CT) as increased density of basal cisterns and subarachnoid spaces from acute blood products. Aneurysmal SAH-like pattern on CT appears as an optical illusion effect of hypodense brain parenchyma and/or hyperdense surrounding cerebral cisterns and blood vessels termed as "pseudo-subarachnoid hemorrhage" (pseudo-SAH)...

Robert Flatman
Harmonization initiatives in laboratory medicine seek to eliminate or reduce illogical variations in service to patients, clinicians and other healthcare professionals. Significant effort will be required to achieve consistent application of terminology, units and reporting across laboratory testing providers. Current variations in practice for nomenclature, reference intervals, flagging, units, standardization and traceability between analytical methods, and presentation of cumulative result data are inefficient and inconvenient, or worse yet, patient safety risks...

Cheng Loong Ngan, Azren Aida Asmawi
Inhalation therapy of lipid-based carriers has great potential in direct target towards the root of respiratory diseases, which make them superior over other drug deliveries. With the successful entry of lipid carriers into the target cells, drugs can be absorbed in a sustained release manner and yield extended medicinal effects. Nevertheless, translation of inhalation therapy from laboratory to clinic especially in drug delivery remains a key challenge to the formulators. An ideal drug vehicle should safeguard the drugs from any premature elimination, facilitate cellular uptake, and promote maximum drug absorption with negligible toxicity...
