Structure and Funding of Clinical Informatics Fellowships: A National Survey of Program Directors.

BACKGROUND: In 2011, the American Board of Medical Specialties established clinical informatics (CI) as a subspecialty in medicine, jointly administered by the American Board of Pathology and the American Board of Preventive Medicine. Subsequently, many institutions created CI fellowship training programs to meet the growing need for informaticists. Although many programs share similar features, there is considerable variation in program funding and administrative structures. OBJECTIVES: The aim of our study was to characterize CI fellowship program features, including governance structures, funding sources, and expenses. METHODS: We created a cross-sectional online REDCap survey with 44 items requesting information on program administration, fellows, administrative support, funding sources, and expenses. We surveyed program directors of programs accredited by the Accreditation Council for Graduate Medical Education between 2014 and 2021. RESULTS: We invited 54 program directors, of which 41 (76%) completed the survey. The average administrative support received was $27,732/year. Most programs (85.4%) were accredited to have two or more fellows per year. Programs were administratively housed under six departments: Internal Medicine (17; 41.5%), Pediatrics (7; 17.1%), Pathology (6; 14.6%), Family Medicine (6; 14.6%), Emergency Medicine (4; 9.8%), and Anesthesiology (1; 2.4%). Funding sources for CI fellowship program directors included: hospital or health systems (28.3%), clinical departments (28.3%), graduate medical education office (13.2%), biomedical informatics department (9.4%), hospital information technology (9.4%), research and grants (7.5%), and other sources (3.8%) that included philanthropy and external entities. CONCLUSION: CI fellowships have been established in leading academic and community health care systems across the country. Due to their unique training requirements, these programs require significant resources for education, administration, and recruitment. There continues to be considerable heterogeneity in funding models between programs. Our survey findings reinforce the need for reformed federal funding models for informatics practice and training.

Formalizing the curbside: digitally enhancing access to specialty care.

Asynchronous medical care has increased in utilization, patient interest, and industry demand. While E-consults have been discussed extensively in the literature, there are rare examples of a multispecialty implementation within a large health system. Here, we describe our experience in implementing an internal E-consult program for asynchronous, nonurgent communication between ambulatory specialists and primary care providers in our large multispecialty regional health system. To ensure adoption of the program, patient, specialist, and primary care physician concerns were systematically addressed. The program commenced in February 2022 with three high referral rate specialties: cardiology, orthopedics, and dermatology. In the 12 months after implementation, 2243 total E-consults were ordered among 505 ordering providers. Dermatology received the most consultations, and we have expanded to 19 specialties and subspecialties available in the program in the first year. Our E-consult implementation experienced substantial growth in a short time period, demonstrating the viability of E-consult utilization for increasing asynchronous access to ambulatory specialists' expertise in a large healthcare system.

The Texas Immuno-Oncology Biorepository, a statewide biospecimen collection and clinical informatics system to enable longitudinal tumor and immune profiling.

A detailed understanding of the molecular and immunological changes that occur longitudinally across tumors exposed to immune checkpoint inhibitors is a significant knowledge gap in oncology. To address this unmet need, we created a statewide biospecimen collection and clinical informatics system to enable longitudinal tumor and immune profiling and to enhance translational research. The Texas Immuno-Oncology Biorepository (TIOB) consents patients to collect, process, store, and analyze serial biospecimens of tissue, blood, urine, and stool from a diverse population of over 100,000 cancer patients treated each year across the Baylor Scott & White Health system. Here we sought to demonstrate that these samples were fit for purpose with regard to downstream multi-omic assays. Plasma, urine, peripheral blood mononuclear cells, and stool samples from 11 enrolled patients were collected from various cancer types. RNA isolated from extracellular vesicles derived from plasma and urine was sufficient for transcriptomics. Peripheral blood mononuclear cells demonstrated excellent yield and viability. Ten of 11 stool samples produced RNA quality to enable microbiome characterization. Sample acquisition and processing methods are known to impact sample quality and performance. We demonstrate that consistent acquisition methodology, sample preparation, and sample storage employed by the TIOB can produce high-quality specimens, suited for employment in a wide array of multi-omic platforms, enabling comprehensive immune and molecular profiling.

An Underappreciated Cytomorphological Feature of Secretory Carcinoma of Salivary Gland on Fine Needle Aspiration Biopsy: Case Report with Literature Review.

Secretory carcinoma (SC) of salivary gland, previously known as mammary analogue secretory carcinoma, is a rare low-grade malignancy harboring a diagnostic ETV6-NTRK3 gene fusion. SC of salivary gland shares histopathological, immunohistochemical and genetic characteristics with SC of the breast. There are several previous cytomorphological characterizations of SC of salivary gland reported in the literature. The most commonly reported patterns are of epithelial clusters with papillary architectural features, or of single dispersed epithelial cells on a background of abundant histiocytes. Tumor cells exhibit vacuolated eosinophilic cytoplasm and round to oval nuclei with regular nuclear contours and inconspicuous or small nucleoli. The cytomorphology of SC may closely mimic that of acinic cell carcinoma or low-grade mucoepidermoid carcinoma. Moreover, when cohesive epithelial clusters do not appear on the smears, it may be very difficult to distinguish dispersed tumor cells from histiocytes. In this article, we review the literature pertaining to SC cytomorphology and we report a fine needle aspiration biopsy case of SC in salivary gland showing well-defined intracytoplasmic hyaline globules, a feature that has not been previously reported. This novel cytomorphological feature may be helpful in distinguishing the tumor cells of SC from histiocytes and from other low-grade salivary gland tumors.

Hippocampal novelty activations in schizophrenia: disease and medication effects.

We examined hippocampal activation in schizophrenia (SZ) with fMRI BOLD in response to the presentation of novel and familiar scenes. Voxel-wise analysis showed no group differences. However, anatomical region-of-interest analyses contrasting normal (NL), SZ-on-medication (SZ-ON), SZ-off-medication (SZ-OFF) showed substantial differences in MTL-based novelty responding, accounted for by the reduction in novelty responses in the SZ-OFF predominantly in the anterior hippocampus and parahippocampal cortex. These differences in novelty-based activation in the SZ-OFF group represent disease characteristics of schizophrenia without confounding effects of antipsychotic medication and illustrate the tendency of antipsychotic drug treatment to improve memory functions in schizophrenia.

Acral myxoinflammatory fibroblastic sarcoma fine needle aspiration: a case report.

Cytological diagnosis of low grade sarcomas can be a daunting task, owing to the varied cytomorphological appearances possible. We report a case of acral myxoinflammatory fibroblastic sarcoma (AMIFS) in a woman who presented with a longstanding mass on the dorsum of her left foot. The diagnosis was suggested by fine needle aspiration cytology and established by wide excision. Microscopic examination showed that fine needle aspirate smears of this lesion contained the characteristic features seen in the surgical excision of this AMIFS: myxoid material, spindled to epithelioid cells with variably prominent nucleoli, nuclear pseudoinclusions, bipolar cytoplasmic extensions, globules of extracellular material, and bizarre virocyte or ganglion-like giant cells.

Clinical experience with the Cervista HPV HR assay: correlation of cytology and HPV status from 56,501 specimens.

Testing for high-risk (HR) human papillomavirus (HPV) is a key component of current recommendations for cervical cancer screening. Herein is described our clinical experience using Cervista HPV HR, a testing platform recently approved by the US Food and Drug Administration for clinical use. Using data from a high-volume commercial laboratory, a retrospective analysis of cytologic and Cervista HPV HR test results from 56,501 samples was performed, and an indirect comparison was made with previous experience with 53,008 samples tested using the Hybrid Capture 2 platform. Of samples analyzed using Cervista HPV HR, 1.5% were of insufficient volume for testing and 1.1% yielded an insufficient signal from the internal control to be reported. In samples with a cytological interpretation of atypical squamous cells of undetermined significance, 48.5% (95% confidence interval [CI], 47.5 to 49.5) tested positive using Cervista HPV HR, compared with 59.4% (95% CI, 58.3 to 60.5) of samples using Hybrid Capture 2. Of samples from women aged 30 years or older with a negative cytological interpretation, 5.8% (95% CI, 5.6 to 6.1) tested positive using Cervista HPV HR, compared with 5.5% (95% CI, 5.3 to 5.7) of samples using Hybrid Capture 2. When stratified by five-year age groups between 30 and 65 years, positivity rates for high-risk human papillomavirus were similar in the Cervista HPV HR and Hybrid Capture 2 populations, and were consistent with expectations established by the literature.

Thyroid carcinoma showing thymus-like differentiation (CASTLE): case report with cytomorphology and review of the literature.

Thyroid carcinoma showing thymus-like differentiation (CASTLE) is a rare tumor of the thyroid gland or adjacent soft tissues of the neck. Given the comparatively good prognosis of CASTLE, it is crucial to distinguish this neoplasm from other more aggressive thyroid neoplasms that can have similar or overlapping cytomorphological features. However, there is little information about the cytomorphology of CASTLE available in the literature. Here we report the cytomorphology and histology of thyroid CASTLE in a 52-year-old woman and present a review of the literature.

Donor cell leukemia in umbilical cord blood transplant patients: a case study and literature review highlighting the importance of molecular engraftment analysis.

Donor cell neoplasms are rare complications of treatment regimens that involve stem cell transplantation for hematological malignancies, myelodysplastic processes, or certain genetic or metabolic disorders. We report a case of donor cell leukemia in a pediatric patient with a history of acute myeloid leukemia that manifested as recurrent AML FAB type M5 fourteen months after umbilical cord blood transplantation. Although there was some immunophenotypic drift from the patient's original AML and their posttransplant presentation, the initial pathological impression was of recurrent disease. Bone marrow engraftment analysis by multiplex PCR of short tandem repeat markers performed on the patient's diagnostic specimen showed complete engraftment by donor cells, with a loss of heterozygosity in the donor alleles on chromosome 7. This led to the reinterpretation of this patient's disease as donor-derived leukemia. This interpretation was supported by a routine karyotype and fluorescence in situ hybridization analysis showing loss of chromosome 7 and a male (donor) chromosome complement in this female patient. Also noted was a loss of the patient's presenting chromosomal abnormality, t(11;19)(q23;p13). This case highlights the need for close coordination between all aspects of clinical testing for the transplant patient, including molecular engraftment studies, when distinguishing the very common complication of recurrent disease from the exceedingly rare complication of donor cell leukemia.

Patterns of GRP78 and MTJ1 expression in primary cutaneous malignant melanoma.

Cell surface expression of glucose-regulated protein 78 (GRP78) occurs in several types of cancer; however, its role in the behavior of primary cutaneous melanoma is not well studied. The association of cell surface GRP78 with other proteins such as MTJ1 stimulates cell proliferation. In this study, we characterized the pattern of expression of GRP78 and MTJ1 in invasive primary cutaneous melanomas and analyzed the relationships between the pattern of expression and various clinicopathological parameters. We found two patterns of GRP78 expression in invasive primary cutaneous melanoma. One pattern showed a gradual fading of protein expression from superficial to deeper levels within the same tumor. The second pattern of expression showed a similar fading with an abrupt regaining of expression at the deep invasive edge of the melanoma. These two distinct patterns of GRP78 expression correlated with both patient survival and depth of tumor invasion. A moderate MTJ1 expression was found to be associated with decreased patient survival; however, no significant associations were observed between patterns of GRP78 and MTJ1 expression. Our study (1) describes two distinct patterns of GRP78 in invasive primary cutaneous melanoma, (2) inversely correlates regain of GRP78 expression with patient survival, and (3) suggests a modifying effect of MTJ1 on GRP78 in enhancing tumor aggressiveness.

Extranodal follicular dendritic cell sarcoma.

Extranodal follicular dendritic cell sarcoma is a rare tumor of follicular dendritic cells that can occur in a wide variety of sites. Although fairly well characterized histologically, with a distinct immunophenotype, it remains under-recognized, with as many as one third of cases initially misdiagnosed. This is often due to a failure to consider the entity. Patients with this tumor may have a worse prognosis than originally described. Prompted by a recent case at our institution, we briefly review the clinical features, etiology, histologic, and cytologic appearance of the tumor, as well as the ancillary studies useful in resolving diagnostic issues, primarily in an attempt to increase recognition of this rare neoplasm.

Hybrid neurofibroma-schwannoma of the orbit.

PURPOSE: To report a case of an unusual orbital tumor with histologic features of both neurofibroma and schwannoma. METHODS: Clinical and pathological findings are presented in a patient with an orbital tumor. RESULTS: Orbital magnetic resonance imaging in a 51-year-old female revealed a heterogeneously enhancing right orbital mass. An anterior orbitotomy was performed, and pathological evaluation revealed a tumor with discrete areas of both neurofibroma and schwannoma. CONCLUSIONS: Hybrid neurofibroma-schwannomas may arise within the orbit.
