The complex network of the tissue system, in both pre-neoplastic tissues and tumors, demonstrates the need for a systems biology approach to cancer pathology, in which quantification of key tissue system processes is combined with informatics tools to produce actionable scores to aid clinical decision-making. A systems biology approach to cancer pathology enables integration of key system features that are relevant to diagnoses, patient outcomes, and responses to therapies. Key tissue system features relevant to cancer pathology include molecular and morphologic abnormalities in epithelia, cellular changes in the stroma such as immune infiltrates, and relationships between components of the system, such as interactions and spatial relationships between epithelial and stromal components, and also between specific immune cell subsets...

Medium-chain acyl-CoA dehydrogenase deficiency (MCADD) is identified by newborn screening (NBS). The natural history of MCADD includes metabolic decompensation with hypoglycemia, hyperammonemia, seizures, coma, and death. NBS enables expectant management thus severe symptoms are rare in managed patients. We report premature birth of an MCADD affected infant and resultant management challenges. Nutritional support advanced from parenteral nutrition at 24 hours to enteral feeds. A NBS sample was collected day 2, positive results for MCADD was reported day six, and diagnostic tests were performed day seven...

Introduction: Next-generation-sequencing (NGS) is increasingly used in clinical and research protocols for patients with cancer. NGS assays are routinely used in clinical laboratories to detect mutations bearing on cancer diagnosis, prognosis and personalized therapy. A typical assay may interrogate 50 or more gene targets that encompass many thousands of possible gene variants. Analysis of NGS data in cancer is a labor-intensive process that can become overwhelming to the molecular pathologist or research scientist...

Many medical centers are faced with a major challenge in making an accurate diagnosis of heparin-induced thrombocytopenia (HIT) and ensuring appropriate changes in management strategy in line with guideline recommendations. We report the initial and long-term impact and challenges of institution-wide changes in the diagnosis and management of HIT in the inpatient setting at an academic medical center. We established a HIT Task Force, consisting of a multidisciplinary team of non-malignant hematologists, nursing, pharmacist, pathology, blood bank and clinical lab informatics...

Clinicians are confronted to an abundance of clinical practice guidelines (CPG). It has been proven for several pathologies that the use of guidelines improves quality of care by reducing mortality, the number of hospitalisations and the length of stay. Despite these proven benefits, adherence to CPGs remains low, mainly due to lack of awareness and familiarity with the guidelines, as well as lack of applicability and flexibility for elderly and comorbid patients. Since adherence to CPGs are influenced by their accessibility and format, informatics will certainly play an important role in the development and implementation of CPGs in the future...

Bioinformatics pipelines are an integral component of next-generation sequencing (NGS). Processing raw sequence data to detect genomic alterations has significant impact on disease management and patient care. Because of the lack of published guidance, there is currently a high degree of variability in how members of the global molecular genetics and pathology community establish and validate bioinformatics pipelines. Improperly developed, validated, and/or monitored pipelines may generate inaccurate results that may have negative consequences for patient care...

Motivation: As a highly heterogeneous disease, the progression of tumor is not only achieved by unlimited growth of the tumor cells, but also supported, stimulated, and nurtured by the microenvironment around it. However traditional qualitative and/or semi-quantitative parameters obtained by pathologist's visual examination have very limited capability to capture this interaction between tumor and its microenvironment. With the advent of digital pathology, computerized image analysis may provide a better tumor characterization and give new insights into this problem...

Peptides play a seminal role in most physiological processes acting as neurotransmitters, hormones, antibiotics, and immune regulation. In the context of tumor biology, it is hypothesized that endogenous peptides, hormones, cytokines, growth factors, and aberrant degradation of select protein networks (e.g., enzymatic activities, protein shedding, and extracellular matrix remodeling) are fundamental in mediating cancer progression. Analysis of peptides in biological fluids by mass spectrometry holds promise of providing sensitive and specific diagnostic and prognostic information for cancer and other diseases...

The first dimension of chemokine heterogeneity is reflected by their discovery and purification as natural proteins. Each of those chemokines attracted a specific inflammatory leukocyte type. With the introduction of genomic technologies, a second wave of chemokine heterogeneity was established by the discovery of putative chemokine-like sequences and by demonstrating chemotactic activity of the gene products in physiological leukocyte homing. In the postgenomic era, the third dimension of chemokine heterogeneity is the description of posttranslational modifications on most chemokines...

Communication between cytopathologists and patients and their care team is a critical component of accurate and timely patient management. The most important single means of communication for the cytopathologist is through the cytopathology report. Implementation of standardized terminology schemes and structured, templated reporting facilitates the ability of the cytopathologist to provide a comprehensive and integrated report. Cytopathology has been among the pathology subspecialties that have led the way in developing standardized reporting, beginning with the 1954 Papanicolaou classification scheme for cervical-vaginal cytology and continuing through the Bethesda systems for gynecological cytology and several nongynecological cytology systems...

Animal research has constituted a fundamental means to achieve groundbreaking therapies for human disease. However, for complex diseases, promising preclinical results have failed to translate to the clinic. Reasons for this disparity are multifactorial. These include the challenges inherent in modeling complex disease in animals, as well issues of study design, reproducibility and operational norms within the biomedical research enterprise. In this issue, we explore the range of information resources available for the comparative study of disease, as well as challenges to the ultimate translation of preclinical findings...
