Laboratory research in Ghana demonstrated the effectiveness of an isolate of Beauveria bassiana (IMI 389521) from the United Kingdom against the larger grain borer Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), a major pest of stored maize. The minimum effective concentration, following artificial infestation trials on maize, was between 10 and 10 cfu/kg maize. Before moving out to village-level control, a major requirement was to determine if the product could effect control in artificially infested maize held under real environmental conditions in several locations in Ghana.

Introduction: During the COVID-19 pandemic, electronic health record (EHR) data has been used to investigate disease severity and risk factors for severe COVID-19 in people with multiple sclerosis (pwMS). Methodological challenges including sampling bias, and residual confounding should be considered when conducting EHR-based studies. We aimed to address these limitations related to the use of EHR data in order to identify risk factors, including the use of disease modifying therapies (DMTs), associated with hospitalization for COVID-19 amongst pwMS.

The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to major challenges in the therapeutic management of patients living with multiple sclerosis (PLwMS), particularly regarding the use of disease-modifying therapies. Despite an extraordinary scientific effort to study SARS-CoV-2 in PLwMS, the heterogeneity of COVID-19 manifestations, immunological mechanisms induced by the natural infection or the vaccines, and the extent of protection through the vaccines, major knowledge gaps remain. Here, we describe the scientific evidence generation plan developed by Roche/Genentech to better understand the impact of the COVID-19 pandemic in PLwMS treated with the B-cell depleting monoclonal antibody ocrelizumab.

Introduction: Ten percent of NSCLCs harbor mutations in SMARCA4, the gene encoding the SWItch/Sucrose Non-Fermentable ATPase BRG1. In preclinical models, BRG1 inactivation increases tumor aggressiveness but enhances sensitivity to drugs that target oxidative phosphorylation and inhibit SMARCA2, EZH2, CDK4, or CDK6. To facilitate translation of preclinical findings into clinical studies exploiting these therapeutic vulnerabilities, we assessed the clinical features of patients with tumors harboring BRG1-inactivating mutations.

Background: Update 3 of the Consortium to Inform Molecular and Practical Approaches to CNS Tumor Taxonomy (cIMPACT-NOW) recognizes amplification of epidermal growth factor receptor (EGFR) as one important aberration in diffuse gliomas (World Health Organization [WHO] grade II/III). While these recommendations endorse testing, a cost-effective, clinically relevant testing paradigm is currently lacking. Here, we use real-world clinical data to propose a financially effective diagnostic test algorithm in the context of new guidelines.

Purpose: mutations are divided into functional classes distinguished by signaling mechanism and kinase activity: V600-mutant kinase-activating monomers (class I), kinase-activating dimers (class II), and kinase-inactivating heterodimers (class III). The relationship between functional class and disease characteristics in BRAF-mutant non-small cell lung cancer (NSCLC) has not been fully explored.

Experimental Design: We performed a retrospective analysis of BRAF-mutant NSCLCs treated at 2 institutions from 2005 to 2017 to determine clinicopathologic characteristics, progression-free survival (PFS) on chemotherapy, and overall survival (OS).

We report a case of a 20-month-old male presenting with seizures who was found to have a hyperintense lesion on T2-weighted images of magnetic resonance imaging in the left medial temporal lobe that was initially clinically and radiologically thought to be either low-grade glioma or focal cortical dysplasia. Histologic, immunohistochemical and molecular evaluation (array comparative genomic hybridization, Archer fusion panel) of the resection specimen demonstrated a highly infiltrative fibroblastic spindle cell neoplasm with mild nuclear atypia and an RBPMS-NTRK3 fusion. NTRK-fused mesenchymal tumors are known to involve extracranial sites but, to our knowledge, have not been described within the central nervous system.

Clonal heterogeneity associated with acquired resistance presents a critical therapeutic challenge. Whole-exome sequencing of paired tumor biopsies and targeted sequencing of cell-free DNA (cfDNA) from patients with colorectal cancer receiving BRAF inhibitor combinations identified 14 distinct alterations in MAPK pathway components driving acquired resistance, with as many as eight alterations in a single patient. We developed a pooled clone system to study clonal outgrowth during acquired resistance, and , the dynamics of individual resistant clones could be monitored in real time in cfDNA isolated from culture media during therapy.

Purpose Advanced anaplastic lymphoma kinase ( ALK) fusion-positive non-small-cell lung cancers (NSCLCs) are effectively treated with ALK tyrosine kinase inhibitors (TKIs). However, clinical outcomes in these patients vary, and the benefit of TKIs is limited as a result of acquired resistance. Emerging data suggest that the ALK fusion variant may affect clinical outcome, but the molecular basis for this association is unknown.

Unlabelled: How genomic heterogeneity associated with acquired resistance to targeted agents affects response to subsequent therapy is unknown. We studied EGFR blockade in colorectal cancer to assess whether tissue and liquid biopsies can be integrated with radiologic imaging to monitor the impact of individual oncogenic alterations on lesion-specific responses. Biopsy of a patient's progressing liver metastasis following prolonged response to cetuximab revealed a MEK1(K57T) mutation as a novel mechanism of acquired resistance.

Unlabelled: MET inhibition is effective in some patients with MET-amplified esophagogastric cancer (EGC), but understanding acquired and de novo resistance mechanisms will be critical to improving therapy. We identified KRAS mutation as a novel cause of acquired resistance in a patient after a 2-year response to a MET inhibitor. We also observed that 40% to 50% of patients with MET-amplified EGC harbor coamplification of HER2 and/or EGFR concurrently in the same tumor cells, which can drive de novo resistance.
