Premedication strategy in cetuximab rechallenge after Grade 2 hypersensitivity reactions.

Introduction: Cetuximab, an IgG1 monoclonal antibody, is utilized in the treatment of metastatic colorectal cancer and squamous cell head and neck cancers. Due to the risk of hypersensitivity reactions, standard premedication with a histamine-1 (H-1) antagonist is recommended prior to administration, however, there is less guidance for premedication strategies to assist with rechallenge after infusion reactions. Here, we describe two cases of successful cetuximab treatment after Grade 2 reactions, in addition to risk factors and proposed premedication strategies for successful rechallenge.

Comprehensive clinical pharmacology characterization of AZD4635 in healthy participants to support dosing considerations.

Aims: Two phase 1 studies characterized the oral bioavailability of AZD4635 (potential anticancer therapy) and factors that may influence its pharmacokinetics (PKs; food, smoking, proton-pump inhibitors [PPIs] and CYP1A2 inhibitors) to support continued clinical development of AZD4635.

Methods: Study 1 (comparative PK study; nonsmokers) consists of Part A and Part B. Participants (fasted) in Part A were administered 50 mg of AZD4635 either as nanosuspension or capsule.

Case report of sacituzumab govitecan-hziy-induced neutropenia in a patient with metastatic triple-negative breast cancer and a uridine diphosphate glucuronosyltransferase family 1 member A1 poor metabolizer genotype.

Introduction: Sacituzumab govitecan-hziy, approved in 2020 for treatment of metastatic triple-negative breast cancer, provides a new option for a population with a historically poor prognosis with standard chemotherapy. Uridine diphosphate glucuronosyltransferase family 1 member A1 poor metabolizers are at increased risk for profound neutropenia. This case discusses clinical implications of the uridine diphosphate glucuronosyltransferase family 1 member A1*28/*28 genotype in patients receiving sacituzumab govitecan-hziy.

A Retrospective Analysis of Metronomic Cyclophosphamide, Methotrexate, and Fluorouracil (CMF) Versus Docetaxel and Cyclophosphamide (TC) as Adjuvant Treatment in Early Stage, Hormone Receptor Positive, HER2 Negative Breast Cancer.

Background: Anthracycline and taxane-based doublets have largely replaced cyclophosphamide, methotrexate, and fluorouracil (CMF) as preferred regimens in the adjuvant treatment of breast cancer. Metronomic CMF is associated with improved tolerability over anthracycline or taxane-based regimens. Previously, there have been no direct comparisons between taxane-based regimens and CMF.

Xerostomia: an immunotherapy-related adverse effect in cancer patients.

Purpose: Xerostomia is an underrecognized adverse effect of immunotherapy (IO) that can significantly impact patients' quality of life by leading to poor nutritional status, dental caries, and oral candidiasis. The purpose of this case series was to describe the onset, severity, clinical course, and management of IO-induced xerostomia.

Methods: This was a retrospective case series conducted at an outpatient cancer center.

Comparison of Binding Site of Remdesivir and Its Metabolites with NSP12-NSP7-NSP8, and NSP3 of SARS CoV-2 Virus and Alternative Potential Drugs for COVID-19 Treatment.

Remdesivir was approved by the U.S.A.

Design and Preliminary Findings From a New Electronic Cohort Embedded in the Framingham Heart Study.

Background: New models of scalable population-based data collection that integrate digital and mobile health (mHealth) data are necessary.

Objective: The aim of this study was to describe a cardiovascular digital and mHealth electronic cohort (e-cohort) embedded in a traditional longitudinal cohort study, the Framingham Heart Study (FHS).

Methods: We invited eligible and consenting FHS Generation 3 and Omni participants to download the electronic Framingham Heart Study (eFHS) app onto their mobile phones and co-deployed a digital blood pressure (BP) cuff.

Evaluation of the Association Between Genetic Variants in Circadian Rhythm Genes and Posttraumatic Stress Symptoms Identifies a Potential Functional Allele in the Transcription Factor .

Previous studies suggest that genetic variants within genes affecting the circadian rhythm influence the development of posttraumatic stress symptoms (PTSS). In the present study, we used data from three emergency care-based cohorts to search genetic variants in circadian pathway genes previously associated with neuropsychiatric disorders for variants that influence PTSS severity. The three cohorts used included a discovery cohort of African American men and women enrolled following motor vehicle collision ( = 907) and two replication cohorts: one of multi-ethnic women enrolled following sexual assault ( = 274) and one of multi-ethnic men and women enrolled following major thermal burn injury ( = 68).

Supervised learning reveals circulating biomarker levels diagnostic of hepatocellular carcinoma in a clinically relevant model of non-alcoholic steatohepatitis; An OAD to NASH.

Although cirrhosis is a key risk factor for the development of hepatocellular carcinoma (HCC), mounting evidence indicates that in a subset of patients presenting with non-alcoholic steatohepatitis (NASH) HCC manifests in the absence of cirrhosis. Given the sheer size of the ongoing non-alcoholic fatty liver disease (NAFLD) epidemic and the dismal prognosis associated with late-stage primary liver cancer there is an urgent need for HCC surveillance in the NASH population. Using serum levels of HCC biomarkers as vectors and biopsy-proven HCC or no HCC as outputs / binary classifier, a supervised learning campaign was undertaken to develop a minimally invasive technique for making a diagnosis of HCC in a clinically relevant model of NASH.
