BACKGROUND: Neuroendocrine phenotype is commonly associated with therapy resistance and poor prognoses in small-cell neuroendocrine cancers (SCNCs), such as neuroendocrine prostate cancer (NEPC) and small-cell lung cancer (SCLC). Expression levels of current neuroendocrine markers exhibit high case-by-case variability, so multiple markers are used in combination to identify SCNCs. Here, we report that ACAA2 is elevated in SCNCs and is a potential molecular indicator for SCNCs.

METHODS: ACAA2 expressions in tumour xenografts, tissue microarrays (TMAs), and patient tissues from prostate and lung cancers were analysed via immunohistochemistry. ACAA2 mRNA levels in lung and prostate cancer (PC) patients were assessed in published …

Journal of Mind and Medical Sciences

Although rare, subungual carcinoma is the most common malignant nail tumor. The symptomatology is not characteristic, being very similar to that of other nail and periungual diseases. For this reason, early diagnosis is usually established by performing a biopsy. With appropriate treatment, subungual carcinoma usually has a favorable prognosis. Metastatic cases are rarely encountered, but they usually have a poor therapeutic result. This article presents the case of a patient with subungual carcinoma (diagnosed by histopathological exam), initially treated by amputation of the distal and middle phalanges of the fourth finger. Two years after the operation, a recurrence in the …

Implications Of Covid-19 On A Rapidly Growing Thymoma Case, Neeraja Narayanan, Shoaleh Motamedi, Christian Lalonde, Mikko Tauriainen

HCA Healthcare Journal of Medicine

Introduction

Thymomas are a rare form of slow-growing malignancy that originate from thymic epithelial cells presenting as an anterior mediastinal mass. Although most are asymptomatic, they can have a variety of presentations, such as local thoracic symptoms, superior vena cava syndrome, or paraneoplastic syndromes. Local compressive thoracic symptoms include shortness of breath, chest pain, and cough. Superior vena cava syndrome presents with respiratory, vascular, or neurologic symptoms. Paraneoplastic syndromes, such as myasthenia gravis, are due to abnormal T-cell maturation leading to an increased risk of autoimmune conditions.

Nitrous Oxide Administration In General Anesthesia Patients, Kaley Smith, Karen Colorafi, Kenn Daratha, Braden Hemingway

Central Division Nurse Clinical Inquiry Conference

Abstract:

Background:

Nitrous oxide is an inexpensive and fast-acting gas used in a variety of inpatient and outpatient perioperative settings to hasten the onset of and emergence from general anesthesia. Problematically, nitrous oxide has been identified as a risk factor for postoperative nausea and vomiting (PONV), one of the most common adverse events after anesthesia. Unresolved PONV is linked to increased pain, wound dehiscence, aspiration, and longer stays in the recovery area and/or hospital. An Apfel Simplified Risk Score can be calculated to predict PONV based on four patient characteristics: female sex, non-smoker, history of PONV or motion sickness, and …

Background.

Organ donors supported by extracorporeal membrane oxygenation (ECMO) have historically been considered high-risk and are judiciously utilized. This study examines transplant outcomes using renal allografts from donors supported on ECMO for nondonation purposes.

Methods.

Retrospective review of the Gift of Life (Pennsylvania, New Jersey, Delaware) organ procurement organization database, cross-referenced to the Organ Procurement and Transplantation Network database, assessed kidney transplants using donors supported on venoarterial (VA) and venovenous (VV) ECMO for nondonation purposes. Transplants using VA- and VV-ECMO donors were compared with Kidney Donor Profile Index (KDPI)-stratified non-ECMO donors. Regression modeling of the entire ECMO and non-ECMO populations …
