Regression modelling is an important statistical tool frequently utilized by cardiothoracic surgeons. However, these models-including linear, logistic and Cox proportional hazards regression-rely on certain assumptions. If these assumptions are violated, then a very cautious interpretation of the fitted model should be taken. Here, we discuss several assumptions and report diagnostics that can be used to detect departures from these assumptions. Most of the diagnostics discussed are based on residuals: a me...

Scientists will be able to obtain information about the flux, spectrum, position, pulse length, and arrival time jitter versus the experimental laser for every photon pulse, with further information about beam shape and size available through the use of des...
Laboratory diagnostics of rheumatic diseases include examinations to confirm the diagnosis, estimate prognosis, assess disease activity as well as recognition and avoidance of complications. Although detection and clinical classification of serological signs of inflammation are the first and often decisive steps in the diagnosis of inflammatory rheumatic diseases, a lack of humoral signs of inflammation does not rule out an inflammatory rheumatic disease. Rheumatological and immunological laboratory diagno...
Sensitization to dog dander is an important risk factor for rhino-conjunctivitis and asthma, but not sufficient for diagnosing dog allergy. Molecular allergy diagnostics offers new opportunities for refined characterization.
Three recent Science articles (Chen et al., 2018; Gootenberg et al., 2018; Myhrvold et al., 2018) describe the use of CRISPR-Cas technology to develop point-of-care diagnostics that directly detect viruses from clinical samples. These tests could radically transform approaches to diagnosing infectious diseases at the bedside and in the field.
Since February 1 2011, rinderpest (RP) has been officially declared eradicated worldwide. National authorities have been requested to destroy all their RP related materials. Nonetheless, their national reference laboratories performing real time reverse transcription polymerase chain reaction assays (PCR diagnostics) need RP positive control samples, since some countries still prefer to maintain diagnostic capability for RP for several reasons. In the future, a similar situation will arise for peste des pet...
Molecular diagnoses have become more widespread in many areas of laboratory medicine where qualitative or quantitative approaches are used to detect nucleic acids. The increasing number of assay methods and the targets for molecular diagnostics contribute to variability in the test results among clinical laboratories. Thus, reference materials (RMs) are required to enhance the comparability of results.
Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, often occur early in life. Therefore, they affect our patient's individual path of life, their ability to work and the quality of life tremendously, which calls for close and comprehensive medical care. This article features 5 cardinal signs and their diagnostics.
Infective diarrhea causes morbidity worldwide. Polymerase chain reaction (PCR)-based pathogen diagnostics of diarrheal stool specimens are shown to be highly sensitive and rapid as opposed to conventional diagnostics.
Cancer remains a global killer alongside cardiovascular disease. A better understanding of cancer biology has transformed its management with an increasing emphasis on a personalized approach, so-called "precision cancer medicine." Imaging has a key role to play in the management of cancer patients. Imaging biomarkers that objectively inform on tumor biology, the tumor environment, and tumor changes in response to an intervention complement genomic and molecular diagnostics. In this review we describe the k...
The growing availability of next-generation sequencing technologies has revolutionized medical genetics, facilitating discovery of causative genes in numerous Mendelian disorders. Nevertheless, there are still many undiagnosed cases. We report the experience of the Genetics Institute at Rambam Health Care Campus in rare disease diagnostics using whole-exome sequencing (WES).
Introduction: The issue of improving the quality of diagnosis, prevention and treatment of patients with pathological scarring of the head and neck is being actively developed throughout the world. The aim of the research is to improve diagnostics of hypertrophic scars of the head and neck through the establishment of structural features of scar-modified tissues using RGB-system and ultrasound examination.
In May 2018, the World Health Organisation (WHO) released the Model List of Essential In Vitro Diagnostics (EDL). In this Commentary we review the EDL components that are relevant to clinical microbiology, particularly antimicrobial stewardship, and formulate some discussion points for future versions of the EDL.

The acute coronary syndrome (ACS) is subdivided into ST segment elevation myocardial infarction (STEMI), non-ST segment elevation acute coronary syndrome (NSTE-ACS) and unstable angina pectoris. It poses a particular challenge in terms of diagnostics and treatment, especially in the elderly. Starting with the possibly difficult anamnesis, through the laboratory chemical findings up to special features in the electrocardiogram (ECG), echocardiography and angiography, these patients should be considered in s...
Central nervous system (CNS) tumors account for the highest mortality among pediatric malignancies. Accurate diagnosis is essential for optimal clinical management. The increasing use of molecular diagnostics has opened up novel possibilities for more precise classification of CNS tumors. We here report a single-institutional collection of pediatric CNS tumor cases that underwent a refinement or a change of diagnosis after completion of molecular analysis that affected clinical decision-making including the...
The impact of the rising colorectal cancer incidence in young adults on the optimal age to start screening: Microsimulation analysis I to inform the American Cancer Society colorectal cancer screening guideline.
In 2016, the Microsimulation Screening Analysis-Colon (MISCAN-Colon) model was used to inform the US Preventive Services Task Force colorectal cancer (CRC) screening guidelines. In this study, 1 of 2 microsimulation analyses to inform the update of the American Cancer Society CRC screening guideline, the authors re-evaluated the optimal screening strategies in light of the increase in CRC diagnosed in young adults.
More than a century ago in 1893, a revolutionary idea about fixing biological tissue specimens was introduced by Ferdinand Blum, a German physician. Since then, a plethora of fixation methods have been investigated and used. Formalin fixation with paraffin embedment became the most widely used types of fixation and preservation method, due to its proper architectural conservation of tissue structures and cellular shape. The huge collection of formalin-fixed, paraffin-embedded (FFPE) sample archives worldwid...
People with HIV infection with latent tuberculosis (TB) infection (LTBI) are at a 10-fold greater risk of developing active disease. Interferon gamma release assays and tuberculin skin testing have approximately 65% to 70% specificity for diagnosing LTBI in HIV-infected patients. LTBI can be successfully treated with isoniazid preventive therapy and early antiretroviral therapy (ART). Rapid molecular diagnostics have approximately 88% sensitivity and 98% specificity for identifying active TB. ART should be ...
We have found that the overproduction of enzymes in bacteria followed by their lyophilization leads to 'cellular reagents' that can be directly used to carry out numerous molecular biology reactions. We demonstrate the use of cellular reagents in a variety of molecular diagnostics, such as TaqMan qPCR with no diminution in sensitivity, and in synthetic biology cornerstones such as the Gibson assembly of DNA fragments, where new plasmids can be constructed solely based on adding cellular reagents. Cellular r...
The major problem for cystic fibrosis patients is the recurrent and chronic infections of the lungs, determining their prognosis. The challenge from biofilm-growing bacteria and emerging viruses urge the microbiological laboratories to develop better and faster diagnostic tools. Of these, molecular diagnostics are rapidly developing. However, beyond detecting many microorganisms, the task is to evaluate their clinical significance. This has always been a problem resulting in Koch's postulates. Then, the tas...
