Identification of allelic variants discovered by atypical typing results on the NEO/Echo platforms.

Some individuals are at risk of anti-D alloimmunization if they inherit D antigens that are qualitatively and/or quantitatively different than wild-type D. We hypothesized that patients who showed serologically inconsistent, weak, or historically discordant D typing results by microplate direct agglutination (MDA) on NEO or Echo (Immucor, Norcross, GA) might be at risk of carrying allelic variants. The present study was designed to evaluate patients with allelic variants if they presented with weakly reactive D typing results on the NEO or Echo.

The Impact of COVID-19 Surge on Clinical Palliative Care: A Descriptive Study From a New York Hospital System.

Context: In spring 2020, New York experienced a surge of patients hospitalized with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or COVID-19) disease, as part of a global pandemic. There are limited data on populations of COVID-19-infected patients seen by palliative care services.

Objective: To describe a palliative care population at one New York hospital system during the initial pandemic surge.

A systematic literature review on the use of platelet transfusions in patients with thrombocytopenia.

Investigate globally, current treatment patterns, benefit-risk assessments, humanistic, societal and economic burden of platelet transfusion (PT). Publications from 1998 to June 27, 2018 were identified, based on databases searches including MEDLINE®; Embase and Cochrane Database of Systematic Reviews. Data from studies meeting pre-specified criteria were extracted and validated by independent reviewers.

Spine stereotactic radiosurgery for metastatic sarcoma: patterns of failure and radiation treatment volume considerations.

OBJECTIVE Given the relatively lower radiosensitivity of sarcomas and the locally infiltrative patterns of spread, the authors sought to investigate spine stereotactic radiosurgery (SSRS) outcomes for metastatic sarcomas and to analyze patterns of failure. METHODS The records of 48 patients with 66 sarcoma spinal metastases consecutively treated with SSRS between 2002 and 2013 were reviewed. The Kaplan-Meier method was used to estimate rates of overall survival (OS) and local control (LC).

Effect of Visceral Disease Site on Outcomes in Patients With Metastatic Castration-resistant Prostate Cancer Treated With Enzalutamide in the PREVAIL Trial.

Background: The Multinational Phase 3, Randomized, Double-Blind, Placebo-Controlled Efficacy and Safety Study of Oral MDV3100 in Chemotherapy-Naive Patients With Progressive Metastatic Prostate Cancer Who Have Failed Androgen Deprivation Therapy (PREVAIL) trial was unique as it included patients with visceral disease. This analysis was designed to describe outcomes for the subgroup of men from PREVAIL with specific sites of visceral disease to help clinicians understand how these patients responded to enzalutamide prior to chemotherapy.

Patients And Methods: Prespecified analyses examined the coprimary endpoints of radiographic progression-free survival (rPFS) and overall survival (OS) only.

Sweet's syndrome associated with clonal hematopoiesis of indeterminate potential responsive to 5-azacitidine.

Sweet's syndrome (SS) is a rare condition characterized by the abrupt appearance of painful skin lesions due to neutrophilic dermal infiltration. Hematologic neoplasms, particularly acute myeloid leukemia (AML) and myelodysplastic syndromes (MDSs), have been commonly reported in association with SS. Clonal hematopoiesis of indeterminate potential (CHIP) is an emerging entity that is a precursor state to myeloid neoplasms.

Stereotactic Body Radiation Therapy for Spinal Metastases in the Postoperative Setting: A Secondary Analysis of Mature Phase 1-2 Trials.

Purpose: To evaluate the outcomes in patients treated on prospective phase 1-2 protocols with postoperative stereotactic body radiation therapy (SBRT) and identify the associated prognostic variables.

Methods And Materials: Sixty-six patients with 69 tumors were treated with SBRT on prospective phase 1-2 studies for spinal metastases between 2002 and 2010. All patients underwent SBRT after spine surgery, which included laminectomy, vertebrectomy, or a combination of these techniques.

Patient experience in the treatment of metastatic castration-resistant prostate cancer: state of the science.

Background: Contemporary therapies for metastatic castration-resistant prostate cancer (mCRPC) have shown survival improvements, which do not account for patient experience and health-related quality of life (HRQoL).

Methods: This literature review included a search of MEDLINE for randomized clinical trials enrolling ⩾50 patients with mCRPC and reporting on patient-reported outcomes (PROs) since 2010.

Results: Nineteen of 25 publications describing seven treatment regimens (10 clinical trials and nine associated secondary analyses) met the inclusion criteria and were critically appraised.

Treatment of high numbers of brain metastases with Gamma Knife radiosurgery: a review.

Effectiveness of stereotactic radiosurgery (SRS) has been shown in patients with one to four brain metastases. Work has been done to evaluate the role of SRS alone treatment without whole-brain radiation therapy in patients with more than four metastases. A recent multiinstitutional JLGK 0901 prospective study revealed the class-2 evidence that SRS without whole-brain radiation therapy is an effective treatment for patients up to 10 metastatic lesions.

Outcomes for Spine Stereotactic Body Radiation Therapy and an Analysis of Predictors of Local Recurrence.

Purpose: To investigate local control, survival outcomes, and predictors of local relapse for patients treated with spine stereotactic body radiation therapy.

Methods And Materials: We reviewed the records of 332 spinal metastases consecutively treated with stereotactic body radiation therapy between 2002 and 2012. The median follow-up for all living patients was 33 months (range, 0-111 months).

Prognostic significance of EGFR and KRAS mutations in NSCLC patients with brain metastases treated with radiosurgery.

Purpose: Determine whether EGFR and KRAS mutations carry prognostic significance in non-small cell lung cancer (NSCLC) patients with brain metastases treated with stereotactic radiosurgery.

Methods And Materials: Ninety-four NSCLC patients with brain metastases initially treated with stereotactic radiosurgery were retrospectively reviewed. Both EGFR and KRAS mutation status were recorded in 67 patients: EGFR+/KRAS- status in 9 patients, EGFR-/KRAS+ in 15 patients, and EGFR-/KRAS- in 43 patients.

Death receptor 3 mediates TNFSF15- and TNFα-induced endothelial cell apoptosis.

Tumor necrosis factor superfamily 15 (TNFSF15) suppresses angiogenesis by specifically inducing apoptosis in proliferating endothelial cells. Death receptor 3 (DR3), a member of the TNF receptor superfamily (TNFRSF25), has been identified as a receptor for TNFSF15 to activate T cells. It is unclear, however, whether DR3 mediates TNFSF15 activity on endothelial cells.

Disruption of primary mesenchyme cell patterning by misregulated ectodermal expression of SpMsx in sea urchin embryos.

The patterning of the mesoderm of the sea urchin embryo is a classical paradigm of epithelial mesenchymal interactions in organogenesis, yet little is known of its molecular basis. Here we address the role of the homeobox gene, SpMsx, a member of the highly conserved Msx gene family, in this process. Msx genes have been shown to function in the dorsoventral patterning of the central nervous system in Drosophila and in a variety epithelial-mesenchymal interactions in vertebrates.

Hodgkin's disease in the setting of human immunodeficiency virus infection.

Although Hodgkin's disease (HD) is not usually associated with congenital or acquired immunodeficiency disorders, recent evidence would suggest a statistically significant increase in HD among individuals infected with human immunodeficiency virus (HIV). In the setting of underlying HIV infection, clinical and pathologic characteristics of HD may differ from usual expectations. Thus, 70%-100% of HIV-infected patients with HD present with systemic "B" symptoms.

Miz1, a novel zinc finger transcription factor that interacts with Msx2 and enhances its affinity for DNA.

Msx2 is a homeobox gene with a regulatory role in inductive tissue interactions, including those that pattern the skull. We demonstrated previously that individuals affected with an autosomal dominant disorder of skull morphogenesis (craniosynostosis, Boston type) bear a mutated form of Msx2 in which a histidine is substituted for a highly conserved proline in position 7 of the N-terminal arm of the homeodomain (p148h). The mutation behaves as a dominant positive in transgenic mice.
