We present health-related quality of life (HRQoL) results from KEYNOTE-604.

ONCOS-102 plus pemetrexed and platinum chemotherapy in malignant pleural mesothelioma: a randomized phase 2 study investigating clinical outcomes and the tumor microenvironment.

Background: ONCOS-102, an oncolytic adenovirus expressing granulocyte-macrophage colony-stimulating factor, can alter the tumor microenvironment to an immunostimulatory state. Combining ONCOS-102 with standard-of-care chemotherapy for malignant pleural mesothelioma (MPM) may improve treatment outcomes.

Methods: In this open-label, randomized study, patients with unresectable MPM received intratumoral ONCOS-102 (3×10 virus particles on days 1, 4, 8, 36, 78, and 120) and pemetrexed plus cisplatin/carboplatin (from day 22), or pemetrexed plus cisplatin/carboplatin alone.

Expression of TILs and Patterns of Gene Expression from Paired Samples of Malignant Pleural Mesothelioma (MPM) Patients.

MPM is an aggressive disease with an immunosuppressive tumor microenvironment, and interest in exploring immunotherapy in this disease has been increasing. In the first line of treatment, the combination of nivolumab and ipilimumab demonstrated an improvement in survival over chemotherapy. The presence of TILs has been recognized as a marker of antitumor immune response to chemotherapy in solid tumors.

Dynamic changes in circulating tumor DNA assessed by shallow whole-genome sequencing associate with clinical efficacy of checkpoint inhibitors in NSCLC.

Immune checkpoint inhibitors (ICIs) targeting the PD-1/PD-L1 axis are the main therapeutic option for patients with advanced non-small cell lung cancer (NSCLC) without a druggable oncogenic alteration. Nevertheless, only a portion of patients benefit from this type of treatment. Here, we assessed the value of shallow whole-genome sequencing (sWGS) on plasma samples to monitor ICI benefit.

The climatic drivers of long-term population changes in rainforest montane birds.

Climate-driven biodiversity erosion is escalating at an alarming rate. The pressure imposed by climate change is exceptionally high in tropical ecosystems, where species adapted to narrow environmental ranges exhibit strong physiological constraints. Despite the observed detrimental effect of climate change on ecosystems at a global scale, our understanding of the extent to which multiple climatic drivers affect population dynamics is limited.

Combination lurbinectedin and doxorubicin versus physician's choice of chemotherapy in patients with relapsed small-cell lung cancer (ATLANTIS): a multicentre, randomised, open-label, phase 3 trial.

Background: Lurbinectedin is a synthetic marine-derived anticancer agent that acts as a selective inhibitor of oncogenic transcription. Lurbinectedin monotherapy (3·2 mg/m every 3 weeks) received accelerated approval from the US Food and Drug Administration on the basis of efficacy in patients with small-cell lung cancer (SCLC) who relapsed after first-line platinum-based chemotherapy. The ATLANTIS trial assessed the efficacy and safety of combination lurbinectedin and the anthracycline doxorubicin as second-line treatment for SCLC.

Environment and Offspring Surveillance in Porcine Brucellosis.

Porcine brucellosis, caused by (), is a notifiable disease causing significant economic losses in production systems. Most infected pigs may act as carriers and shed even if asymptomatic. This can contribute to environmental persistence, thus hindering control efforts.

Overview of Checkpoint Inhibitors Mechanism of Action: Role of Immune-Related Adverse Events and Their Treatment on Progression of Underlying Cancer.

In recent years, immunotherapy-based regimens have been included into the treatment's algorithm of several cancer types. Programmed death-1 (PD-1) and cytotoxic T lymphocyte antigen-4 (CTLA-4) interact with their ligands found on the surface of antigen presenting cells (APC) or tumor cells (PD-L1/2 and CD80/86). Through these interactions, stimulatory or inhibitory signals are established.

High levels of chromosomal aberrations negatively associate with benefit to checkpoint inhibition in NSCLC.

Background: Immune checkpoint inhibitors (ICIs) targeting the programmed cell death 1/programmed death-ligand 1 axis have transformed the management of advanced non-small cell lung cancer (NSCLC). However, many patients do not benefit from this type of treatment, and thus several molecular biomarkers of benefit have been explored. The value of somatic copy number alterations (SCNAs) burden remains elusive.

Phase Ib/II study of ceritinib in combination with ribociclib in patients with ALK-rearranged non-small cell lung cancer.

Background: Preclinical data show that the combination of an ALK inhibitor (ALKi) with a cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) may act synergistically to overcome drug resistance mechanisms. Here, we assessed the safety, tolerability, and preliminary clinical activity of ceritinib, an ALKi in combination with ribociclib, a CDK4/6i, in patients with ALK-rearranged non-small cell lung cancer (NSCLC).

Methods: This was a multicenter, open-label, phase Ib/II dose-escalation study to determine the maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) for ceritinib plus ribociclib therapy.

Randomized phase 3 study of the anti-disialoganglioside antibody dinutuximab and irinotecan vs irinotecan or topotecan for second-line treatment of small cell lung cancer.

Introduction: Topotecan is approved as second-line treatment for small cell lung cancer (SCLC). Irinotecan is also frequently used given its more convenient schedule and superior tolerability. Preclinical studies support disialoganglioside (GD2) as an SCLC target and the combination of dinutuximab, an anti-GD2 antibody, plus irinotecan in this setting.

Comparison of concanavalin A and poly-l-lysine as cell adhesives for routine yeast microscopy applications.

A frequently encountered problem with imaging budding yeast specimens by light microscopy is that the cells do not adhere well to glass microscope slides. Frustratingly, cells that initially appear stationary in the visual field often become displaced and float away. The development of immunofluorescence microscopy methods for yeast led to the widespread use of poly-l-lysine as an adhesive for cell immobilization.
