Rabbit hemorrhagic disease virus 2 (RHDV2) emerged in the United States in 2018 and has spread in both domestic and wild rabbits nationwide. The virus has a high mortality rate and can spread rapidly once introduced in a rabbit population. Vaccination against RHDV2 provides the best protection against disease and should be considered by all rabbit owners.

The formation of a phototropin activation gradient across a photosensitive organ initiates this response. However, the optical tissue properties that functionally contribute to phototropism remain unclear.

Introduction: Lung cancer is most common in older patients; despite this, older patients are historically under-represented in clinical studies. Here we present data from GIDEON, a study undertaken in Germany in patients with epidermal growth factor receptor mutation-positive (EGFRm+) non-small cell lung cancer (NSCLC) receiving first-line afatinib. GIDEON enrolled a high proportion of patients aged ≥70 years, providing an opportunity to study afatinib use in older patients.

Objectives: Our aim was to deploy and prospectively evaluate an already developed delirium prediction software in clinical routine of an external hospital.
Methods: We compared updated ML models of the software and models re-trained with the external hospital's data.

The ICH E9(R1) addendum on Estimands and Sensitivity Analyses in Clinical Trials has introduced a new estimand framework for the design, conduct, analysis, and interpretation of clinical trials. We share Pharmaceutical Industry experiences of implementing the estimand framework in the first two years since the final guidance became available with key lessons learned and highlight what else needs to be done to continue the journey in embedding the estimand framework in clinical trials. Emerging best practices and points to consider on strategies for implementing a new estimand thinking process are provided.

Here we show a cooperative Ni single-atom-on-nanoparticle catalyst (NiSA/NP) prepared via direct solid-state pyrolysis, where Ni nanoparticles donate electrons to Ni(i)-N-C sites via a network of carbon nanotubes, achieving a high CO current density of 346 mA cm at -0.5 V vs RHE in an alkaline flow cell.

Objectives: The aim of this study was to describe the efficacy, safety, and pharmacodynamics of pimasertib at pharmacologically active doses in a cohort of patients with locally advanced/metastatic melanoma from a first-in-human study of pimasertib.

Organizational commitment to a structured professional advancement model (PAM) is critical for advanced practice provider (APP) development in order to promote and reward excellence, enhance job satisfaction and improve retention and recruitment. A PAM may also serve as a motivational tool for personal and professional growth by developing and promoting a professional, evidence-based collaborative practice environment. A voluntary PAM was implemented at a large Midwestern academic medical center to recognize experienced APPs including certified nurse practitioners, certified nurse-midwives and physician assistants.

This study investigated the efficacy and safety of pimasertib (1/2 inhibitor) versus dacarbazine (DTIC) in patients with untreated -mutated melanoma. Phase II, multicenter, open-label trial. Patients with unresectable, stage IIIc/IVM1 -mutated cutaneous melanoma were randomized 2:1 to pimasertib (60 mg; oral twice-daily) or DTIC (1000 mg/m; intravenously) on Day 1 of each 21-day cycle.

Purpose: This study aimed to confirm the recommended phase II dose (RP2D) of pimasertib in Japanese patients.
Methods: This two-part, phase I dose-escalation and expansion study was conducted in Japanese patients (≥ 18 years old) with advanced solid tumors (ST) including hepatocellular carcinoma (HCC). In Part 1, patients with ST (Arm A) and HCC (Arm B) received escalating doses (3 + 3 design) of oral pimasertib [starting at 45 mg twice daily (BID)] in 21-day cycles, until disease progression or unacceptable toxicity.
The selective MEK1/2 inhibitor pimasertib has shown anti-tumour activity in a pancreatic tumour model. This phase I/II, two-part trial was conducted in patients with metastatic pancreatic adenocarcinoma (mPaCa) (NCT01016483). In the phase I part, oral pimasertib was given once daily discontinuously (5 days on/2 days off treatment) or twice daily continuously (n = 53) combined with weekly gemcitabine (1,000 mg/m ) in 28-day cycles to identify the recommended phase II dose (RP2D) of pimasertib.

With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of materials. In parallel, strongly correlated functional oxides have emerged, having the ability to show reversible insulator-to-metal (IMT) phase transition by collapsing their electronic bandgap under a certain external stimulus.

We investigated whether candidate biomarkers were predictive for the efficacy of chemotherapy plus cetuximab in this setting.
Methods: Genomic DNA extracted from formalin-fixed paraffin-embedded (FFPE) tumour tissue of patients enrolled in the FLEX study was screened for KRAS codon 12 and 13 and EGFR kinase domain mutations with PCR-based assays.

Intraocular medulloepithelioma is an extremely rare unilateral intraocular tumor arising from the nonpigmented ciliary epithelium. Medulloepitheliomas may be classified as benign and malignant and as teratoid and nonteratoid tumors. As a rule a long latency period occurs after first symptoms until the final diagnosis of a medulloepithelioma is made.

We investigated the efficacy of cetuximab plus platinum-based chemotherapy as first-line treatment in patients with recurrent or metastatic squamous-cell carcinoma of the head and neck.
Methods: We randomly assigned 220 of 442 eligible patients with untreated recurrent or metastatic squamous-cell carcinoma of the head and neck to receive cisplatin (at a dose of 100 mg per square meter of body-surface area on day 1) or carboplatin (at an area under the curve of 5 mg per milliliter per minute, as a 1-hour intravenous infusion on day 1) plus fluorouracil (at a dose of 1000 mg per square meter per day for 4 days) every 3 weeks for a maximum of 6 cycles and 222 patients to receive the same chemotherapy plus cetuximab (at a dose of 400 mg per square meter initially, as a 2-hour intravenous infusion, then 250 mg per square meter, as a 1-hour intravenous infusion per week) for a maximum of 6 cycles.

The authors aimed to preclinically assess the effects of photochemotherapy using second-generation photochemotherapeutics as a prerequisite to develop a promising therapeutic alternative. This therapy implies intravenous application of a photosensitizer activated locally by light of the appropriate wavelength.

Patients And Methods: An open-label multicenter study in which patients with disease progression on two to six cycles of platinum therapy received single-agent cetuximab (initial dose 400 mg/m2 followed by subsequent weekly doses of 250 mg/m2) for > or = 6 weeks (single-agent phase). Patients who experienced disease progression could receive salvage therapy with cetuximab plus platinum (combination-therapy phase).
Purpose: This was an open, randomized, multicenter, phase I/II study to investigate the safety and tolerability of cetuximab in the first-line treatment of recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN).
Patients And Methods: Treatment comprised cetuximab (initial dose 400 mg/m2 with subsequent weekly doses of 250 mg/m2) in combination with 3-week cycles of either cisplatin (100 mg/m2) or carboplatin (area under the curve, 5), each in combination with a 5-day infusion of fluorouracil (FU) at escalating doses of 600, 800, and 1,000 mg/m2/d. The study was divided into two phases: A, the first two cycles (6 weeks) focusing on the safety and tolerability of combination therapy; and B, the remaining time for those benefiting from therapy until disease progression or intolerable toxicity.
