Effect of TPE vs medical management on patient outcomes in the setting of hypertriglyceridemia-induced acute pancreatitis with severely elevated triglycerides.

Objectives: Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) accounts for 1 to 10% of pancreatitis cases, and is associated with a more severe clinical course. Therapeutic plasma exchange (TPE) is a potential treatment option for quickly lowering plasma triglycerides (TG). Current ASFA guidelines define HTG-AP as a Category III disorder, indicating the role of apheresis is not firmly established.

A Survey of LOINC Code Selection Practices Among Participants of the College of American Pathologists Coagulation (CGL) and Cardiac Markers (CRT) Proficiency Testing Programs.

Context.—: Biomedical terminologies such as Logical Observation Identifiers, Names, and Codes (LOINC) were developed to enable interoperability of health care data between disparate health information systems to improve patient outcomes, public health, and research activities.

Objective.

Impact of Hormone Therapy on Laboratory Values in Transgender Patients.

Background: For transgender individuals taking hormone therapy (HT), data on laboratory values are limited, and the effects on laboratory values cannot be easily predicted. We evaluated the impact on common laboratory analytes in transgender individuals before and after initiation of HT.

Methods: We conducted a retrospective chart review of transgender patients identified at transgender-specific clinics at an urban county hospital and community clinic.

Agreement between cytotechnologists and cytopathologists as a new measure of cytopathologist performance in gynecologic cytology.

Background: Although objective measures of cytotechnologist (CT) and cytopathologist (CP) performance exist, challenges remain. Two assumptions deserve examination: CPs' interpretations are correct, and CTs and CPs render interpretations independently of each other. This study presents a CT-CP interpretation comparison and provides insight into these assumptions.

Metastatic Melanoma to the Bladder: Case Report and Review of the Literature.

A 49-year-old Caucasian woman presented to the dermatology clinic for follow-up of malignant melanoma with a complaint of painless gross hematuria. Two years prior she was diagnosed with malignant melanoma from a skin lesion on her left flank treated with wide excision, negative axillary sentinel lymph node biopsy, and adjuvant radiotherapy. Subsequently, she had no evidence of disease until urologic evaluation of her hematuria revealed two lesions in her bladder and cytopathology demonstrated findings consistent with malignant melanoma.

The ongoing evolution of the core curriculum of a clinical fellowship in pathology informatics.

The Partners HealthCare system's Clinical Fellowship in Pathology Informatics (Boston, MA, USA) faces ongoing challenges to the delivery of its core curriculum in the forms of: (1) New classes of fellows annually with new and varying educational needs and increasingly fractured, enterprise-wide commitments; (2) taxing electronic health record (EHR) and laboratory information system (LIS) implementations; and (3) increasing interest in the subspecialty at the academic medical centers (AMCs) in what is a large health care network. In response to these challenges, the fellowship has modified its existing didactic sessions and piloted both a network-wide pathology informatics lecture series and regular "learning laboratories". Didactic sessions, which had previously included more formal discussions of the four divisions of the core curriculum: Information fundamentals, information systems, workflow and process, and governance and management, now focus on group discussions concerning the fellows' ongoing projects, updates on the enterprise-wide EHR and LIS implementations, and directed questions about weekly readings.

Intrapopulation genome size variation in D. melanogaster reflects life history variation and plasticity.

We determined female genome sizes using flow cytometry for 211 Drosophila melanogaster sequenced inbred strains from the Drosophila Genetic Reference Panel, and found significant conspecific and intrapopulation variation in genome size. We also compared several life history traits for 25 lines with large and 25 lines with small genomes in three thermal environments, and found that genome size as well as genome size by temperature interactions significantly correlated with survival to pupation and adulthood, time to pupation, female pupal mass, and female eclosion rates. Genome size accounted for up to 23% of the variation in developmental phenotypes, but the contribution of genome size to variation in life history traits was plastic and varied according to the thermal environment.

The 2013 symposium on pathology data integration and clinical decision support and the current state of field.

Background: Pathologists and informaticians are becoming increasingly interested in electronic clinical decision support for pathology, laboratory medicine and clinical diagnosis. Improved decision support may optimize laboratory test selection, improve test result interpretation and permit the extraction of enhanced diagnostic information from existing laboratory data. Nonetheless, the field of pathology decision support is still developing.

Polypectomy is adequate treatment for adenoma-like dysplastic lesions (DALMs) in Crohn's disease.

Background: The purpose of this study was to reevaluate the clinical and pathologic features and outcomes in patients with Crohn's disease with an adenoma-like dysplasia-associated lesion or mass (DALMs) to determine if polypectomy is adequate treatment.

Methods: The clinical, endoscopic and pathologic features, and outcomes of 50 patients with Crohn's disease, each with ≥1 adenoma-like DALM were evaluated. The median length of follow-up was 39 months (range: 0.

Tissue array construction: pitfalls, problems, and progress.

The tissue array is an economical and efficient tool for translational research. An important factor in constructing tissue arrays is the ability to reliably transfer the pathologic feature of interest from the donor block to the array block. The precision of this transfer is undermined by the distortion of dotted routine sections, which serve as the primary feature-finding device for manual array construction, and by certain tissues such as breast, colon, and skin that prove resistant to being punched.

Differential expression of interleukin-8 and its receptors in the neuroendocrine and non-neuroendocrine compartments of prostate cancer.

Hormonal therapy (androgen ablation and/or inhibition of androgen action) is the treatment of choice for advanced prostate cancer. After an initial response in most patients, tumors invariably progress to an androgen-independent state. It is unclear how prostate cancer cells proliferate without androgen.
