Race/ethnicity-based discrimination, depressive symptoms, and smoking-related variables among people with HIV participating in a randomized clinical trial for cigarette smoking cessation.

People with HIV smoke cigarettes at a high prevalence, and it is important to identify modifiable variables related to smoking in this population. Race/ethnicity-based discrimination is common among people with HIV from minoritized racial and ethnic groups and results in significant adverse effects. The goal of this study was to examine the relationship between race/ethnicity-based discrimination, depression, and smoking-related variables among people with HIV who smoke.

Perioperative Segmentation of the Posterior Fossa and the Keel of Goodrich in Surgical Outcomes of Chiari Malformations.

Background: Chiari I malformation (CM-I) is defined as the extension of brain tissue into the spinal cord. This study aimed to refine the methodology for the acquisition of 3-dimensional measurements of the posterior fossa and introduce occipital keel size as a new marker and its impact in patients with CM.

Methods: In this retrospective study, all patients who underwent Chiari decompression surgery at Montefiore Medical Center from April 2012 to April 2022 were included.

Nuanced Management of a Skull Base Tumor in the Setting of Relapsed Acute Lymphoblastic Leukemia.

 Relapsed acute lymphoblastic leukemia (ALL) involving the central nervous system (CNS) is a significant issue that contributes to both morbidity and mortality. Given the poor outcomes in patients with CNS relapse, understanding how ALL involving intracranial relapse presents and is treated is critical. Here, we present a complex case of relapsed recurrent ALL in a pediatric patient.

Volumetric segmentation in the context of posterior fossa-related pathologies: a systematic review.

Background: Segmentation tools continue to advance, evolving from manual contouring to deep learning. Researchers have utilized segmentation to study a myriad of posterior fossa-related conditions, such as Chiari malformation, trigeminal neuralgia, post-operative pediatric cerebellar mutism syndrome, and Crouzon syndrome. Herein, we present a summary of the current literature on segmentation of the posterior fossa.

Image-based multiplex immune profiling of cancer tissues: translational implications. A report of the International Immuno-oncology Biomarker Working Group on Breast Cancer.

Recent advances in the field of immuno-oncology have brought transformative changes in the management of cancer patients. The immune profile of tumours has been found to have key value in predicting disease prognosis and treatment response in various cancers. Multiplex immunohistochemistry and immunofluorescence have emerged as potent tools for the simultaneous detection of multiple protein biomarkers in a single tissue section, thereby expanding opportunities for molecular and immune profiling while preserving tissue samples.

A Case Report of Infant-Type Hemispheric Glioma with a Novel GAB1-ABL2 Kinase Fusion Treated with Dasatinib.

Introduction: Infant-type hemispheric glioma (IHG) is a rare form of cancer that affects newborns and infants. It is classified as a pediatric-type high-grade glioma and typically harbors receptor tyrosine kinase (RTK) gene fusions. Here, we present the finding of a novel gene fusion IHG treated with a targeted therapy that has yet to be implemented for any other IHG case to date.

High-Sensitivity vs Conventional Troponin Cutoffs for Risk Stratification in Patients With Acute Pulmonary Embolism.

Importance: High-sensitivity troponin tests can detect even milder cardiac troponin elevations in plasma, beyond the threshold of conventional troponin tests. Whether detection of low-grade cardiac troponin elevation is associated with outcomes of patients with hemodynamically stable pulmonary embolism (PE) and helps with risk stratification is unknown.

Objective: To determine the association between high-sensitivity cardiac troponin I (hs-cTnI) compared with conventional cardiac troponin I (cTnI) and PE risk designations according to the European Society of Cardiology (ESC) 2019 classification scheme and clinical outcomes in patients with hemodynamically stable PE.

Case Report: Treatment of the rare B-cell lymphoblastic lymphoma with scalp lesion using rotation flap.

Introduction: Leukemia is the most frequently occurring cancer in children, and lymphoblastic lymphoma (LBL) is a rare subtype. LBL are lymphoid neoplasms of B or T cell origin and are primarily treated with chemotherapy. Although cure rates among children are excellent, these patients must be monitored for relapse.

Spatial analyses of immune cell infiltration in cancer: current methods and future directions: A report of the International Immuno-Oncology Biomarker Working Group on Breast Cancer.

Modern histologic imaging platforms coupled with machine learning methods have provided new opportunities to map the spatial distribution of immune cells in the tumor microenvironment. However, there exists no standardized method for describing or analyzing spatial immune cell data, and most reported spatial analyses are rudimentary. In this review, we provide an overview of two approaches for reporting and analyzing spatial data (raster versus vector-based).

STAT5b gain-of-function disease in a child with mycobacterial osteomyelitis of the skull: rare presentation of an emerging disease entity.

Purpose: STAT proteins play a key role in several cellular functions related to cell development, differentiation, proliferation, and survival. Persistent STAT activation due to somatic STAT5b gain-of-function mutation is a rare mechanism of STAT dysregulation that results in hypereosinophilia, frequent infections, leukemias, and pulmonary diseases. Herein, we describe a case of a child with a rare early onset STAT5b gain-of-function disease treated with targeted JAK inhibition who developed a cranial Mycobacterium avium osteomyelitis.

Scintigraphic Diagnosis of Acute Pulmonary Embolism: From Basics to Best Practices.

In this article the technique, interpretation, and diagnostic performance of scintigraphy for the diagnosis of acute pulmonary embolism (PE) are reviewed. Lung scintigraphy has stood the test of time as a reliable and validated examination for the determination of PE. Ventilation/perfusion (V/Q) lung scintigraphy assesses the functional consequences of the clot on its downstream vascular bed in conjunction with the underlying ventilatory status of the affected lung region, in contrast to CT pulmonary angiography (CTPA), which visualizes presence of the clot within affected vessels.

Substance Use and Adherence to Antiretroviral Therapy among People Living with HIV in the United States.

People with HIV (PWH) report substance use at higher rates than HIV-uninfected individuals. The potential negative impact of single and polysubstance use on HIV treatment among diverse samples of PWH is underexplored. PWH were recruited from the Center for Positive Living at the Montefiore Medical Center (Bronx, NY, USA) from May 2017-April 2018 and completed a cross-sectional survey with measures of substance use, antiretroviral therapy (ART) use, and ART adherence.

Analysis of Outpatient Adherence in 45,237 Patients Referred by an Emergency Department to Surgical Clinics.

Introduction: This study examines referral patterns to surgical clinics from the emergency department and the impact of sociodemographic factors on adherence.

Methods: Patients from 2017 to 2021 were identified who had a referral placed to surgical specialties from the ED. The primary outcome was the proportion of patients who had a referral to surgery placed during an ED visit but who showed up to surgery clinic visit within 60 days of referral placement.

Effectiveness of Bariatric Surgery Targeting Opioid Prescriptions (BSTOP) protocol on postoperative pain control.

Background: Surgical pain management is a critical component in the success of bariatric procedures. With the opioid epidemic, there have been increased efforts to decrease opioid use. In 2019, the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program developed the BSTOP protocol, a multimodal perioperative pain management regimen to minimize opioid use.

MiRNA expression deregulation correlates with the Oncotype DX DCIS score.

Background: Current clinical criteria do not discriminate well between women who will or those who will not develop ipsilateral invasive breast cancer (IBC), or a DCIS recurrence after a ductal carcinoma in situ (DCIS) diagnosis. The 12-gene Oncotype DX® DCIS assay (RT qPCR gene-based scoring system) was established and shown to predict the risk of subsequent ipsilateral IBC or DCIS recurrence. Recent studies have shown that microRNA (miRNA) expression deregulation can contribute to the development of IBC, but very few have evaluated miRNA deregulation in DCIS lesions.

Incidental Primary Intrathoracic Goiter: Dual-Isotope Scintigraphy and Early-MIBI SPECT/CT.

Primary intrathoracic goiter is an uncommon congenital entity resulting from over decent ectopic thyroid tissue. As compared with secondary intrathoracic goiter, primary entities are discrete from orthotopic thyroid tissue and may lead to potentially serious complications such as malignancy and shortness of breath. Intrathoracic goiters have been described as showing mild or absent uptake of Tc-pertechnetate on planar scintigraphy.
