Treatment of Established Chemotherapy-Induced Neuropathy with N-Palmitoylethanolamide: A Randomized, Double-Blind Phase II Pilot Study.

Chemotherapy-induced peripheral neuropathy (CIPN) from oxaliplatin and taxane drugs is a bothersome toxicity. Palmitoylethanolamide (PEA) has been reported to improve myelinated nerve fiber function in patients experiencing painful CIPN. We conducted a double-blind, placebo-controlled, randomized trial of PEA in patients with established CIPN.

Long-time emergent dynamics of liquid films undergoing thermocapillary instability.

The study of viscous thin film flow has led to the development of highly nonlinear partial differential equations that model how the evolution of the film height is affected by different forces. We investigate a model of interaction between surface tension and the thermocapillary Marangoni effect, with a particular focus on the long-time limit. In this limit, the model predicts the creation of an infinite cascade of successively smaller satellite droplets near points where the film thickness vanishes.

Self-Reported Financial Difficulties Among Patients with Multiple Myeloma and Chronic Lymphocytic Leukemia Treated at U.S. Community Oncology Clinics (Alliance A231602CD).

Objectives: To estimate the proportion and correlates of self-reported financial difficulty among patients with multiple myeloma (MM) or chronic lymphocytic leukemia (CLL).

Setting: 23 U.S.

Clonal Hematopoiesis in Patients With Neuroendocrine Tumor Treated With Lutetium-177 and the Risk of Thrombocytopenia: A Prospective Study.

Purpose: Thrombocytopenia is a relatively common dose-limiting toxicity during peptide receptor radionuclide therapy (PRRT) in patients with NET. Although uncommon, some patients develop persistent cytopenia and eventually therapy-related myeloid neoplasm (t-MN), which has a dismal prognosis. As the indications for PRRT are expanding, it is important to investigate factors that may predict cytopenias during/after PRRT.

Alliance A151945: Accrual and characteristics of adolescent and young adult patients in Alliance trials from 2000 to 2017.

Background: Identifying patient- and disease-specific characteristics associated with clinical trial enrollment of adolescents and young adults (AYAs) with cancer may target efforts to improve accrual.

Methods: Alliance for Clinical Trials in Oncology (Alliance) trials opened from January 1, 2000, and closed before January 1, 2018, for common AYA cancers were identified. Proportions of AYAs (aged 18-39 years old) versus non-AYAs (aged ≥40 years old) enrolled by cancer type were summarized by descriptive statistics.

A five arm natural history study of nasal vestibulitis.

Introduction: Nasal symptoms are frequently reported by patients undergoing chemotherapy.

Methods: Eligible patients planning to receive paclitaxel, docetaxel, nab-paclitaxel, bevacizumab without a concomitant taxane, or "other" (non-taxane, non-bevacizumab) chemotherapy regimens were invited to participate in this prospective study. Patients reported nasal symptoms prior to each dose of chemotherapy.

Interchange of Southern Hemisphere humpback whales across the South Atlantic Ocean.

The cosmopolitan distribution of humpback whales (Megaptera novaeangliae) is largely driven by migrations between winter low-latitude breeding grounds and summer high-latitude feeding grounds. Southern Hemisphere humpback whales faced intensive exploitation during the whaling eras and recently show evidence of population recovery. Gene flow and shared song indicate overlap between the western (A) and eastern (B1, B2) Breeding Stocks in the South Atlantic and Indian Oceans (C1).

Applications and clinical trial landscape using Toll-like receptor agonists to reduce the toll of cancer.

Toll-like receptors (TLRs), which serve as a bridge between innate and adaptive immunity, may be viable treatment targets. TLRs are the first line of defense against microbes and activate signaling cascades that induce immune and inflammatory responses. Patients with "hot" versus "cold" tumors may respond more favorably to immune checkpoint inhibition, and through their downstream effects, TLR agonists have the potential to convert "cold tumors" into "hot tumors" making TLRs in combination with immune checkpoint inhibitors, potential targets for cancer therapies.

Profile likelihood-based parameter and predictive interval analysis guides model choice for ecological population dynamics.

Calibrating mathematical models to describe ecological data provides important insight via parameter estimation that is not possible from analysing data alone. When we undertake a mathematical modelling study of ecological or biological data, we must deal with the trade-off between data availability and model complexity. Dealing with the nexus between data availability and model complexity is an ongoing challenge in mathematical modelling, particularly in mathematical biology and mathematical ecology where data collection is often not standardised, and more broad questions about model selection remain relatively open.

Successes and lessons learned in database development for national multi-site cancer care delivery research trials: the Alliance for Clinical Trials in Oncology experience.

Introduction: Alliance for Clinical Trials in Oncology (Alliance) coordinated trials utilize Medidata Rave® (Rave) as the primary clinical data capture system. A growing number of innovative and complex cancer care delivery research (CCDR) trials are being conducted within the Alliance with the aims of studying and improving cancer-related care. Because these trials encompass patients, providers, practices, and their interactions, a defining characteristic of CCDR trials is multilevel data collection in pragmatic settings.

Non-vanishing sharp-fronted travelling wave solutions of the Fisher-Kolmogorov model.

The Fisher-Kolmogorov-Petrovsky-Piskunov (KPP) model, and generalizations thereof, involves simple reaction-diffusion equations for biological invasion that assume individuals in the population undergo linear diffusion with diffusivity $D$, and logistic proliferation with rate $\lambda $. For the Fisher-KPP model, biologically relevant initial conditions lead to long-time travelling wave solutions that move with speed $c=2\sqrt {\lambda D}$. Despite these attractive features, there are several biological limitations of travelling wave solutions of the Fisher-KPP model.

Impact of apremilast on quality of life in Behçet's syndrome: analysis of the phase 3 RELIEF study.

Objective: To assess apremilast's impact on patient quality of life (QoL) in active Behçet's syndrome and correlations between improvement in patients' QoL and efficacy measures in the phase 3 RELIEF study.

Methods: QoL measures included Behçet's Disease QoL (BDQoL), 36-Item Short-Form Health Survey V.2 (SF-36v2) Physical/Mental Component Summary (PCS/MCS) and eight subscale scores, focusing on Physical Functioning (PF).

A Continuum Mathematical Model of Substrate-Mediated Tissue Growth.

We consider a continuum mathematical model of biological tissue formation inspired by recent experiments describing thin tissue growth in 3D-printed bioscaffolds. The continuum model, which we call the substrate model, involves a partial differential equation describing the density of tissue, [Formula: see text] that is coupled to the concentration of an immobile extracellular substrate, [Formula: see text]. Cell migration is modelled with a nonlinear diffusion term, where the diffusive flux is proportional to [Formula: see text], while a logistic growth term models cell proliferation.

Apremilast in a Japanese subgroup with Behçet's syndrome: Results from a Phase 3, randomised, double-blind, placebo-controlled study.

Objectives: Apremilast efficacy and safety was assessed in a prespecified subgroup of Japanese patients with oral ulcers associated with Behçet's syndrome from a Phase 3 randomized, placebo-controlled, double-blind study of apremilast (RELIEF).

Methods: The primary end point was area under the curve for number of oral ulcers during the 12-week placebo-controlled phase (AUCWk0-12). Key secondary end points were change from baseline in oral ulcer pain, complete oral ulcer resolution, and measures of disease activity and quality of life (QoL).

Histone deacetylase 3 represses cholesterol efflux during CD4 T-cell activation.

After antigenic activation, quiescent naive CD4 T cells alter their metabolism to proliferate. This metabolic shift increases production of nucleotides, amino acids, fatty acids, and sterols. Here, we show that histone deacetylase 3 (HDAC3) is critical for activation of murine peripheral CD4 T cells.

The mitochondrial iron transporter ABCB7 is required for B cell development, proliferation, and class switch recombination in mice.

Iron-sulfur (Fe-S) clusters are cofactors essential for the activity of numerous enzymes including DNA polymerases, helicases, and glycosylases. They are synthesized in the mitochondria as Fe-S intermediates and are exported to the cytoplasm for maturation by the mitochondrial transporter ABCB7. Here, we demonstrate that ABCB7 is required for bone marrow B cell development, proliferation, and class switch recombination, but is dispensable for peripheral B cell homeostasis in mice.

Apremilast for oral ulcers associated with active Behçet's syndrome over 68 weeks: long-term results from a phase 3 randomised clinical trial.

Objectives: This study assessed the efficacy and safety of apremilast for the oral ulcers associated with Behçet's syndrome (BS) up to 64 weeks.

Methods: The phase 3, double-blind, placebo-controlled RELIEF study randomised adult patients with active BS to placebo or apremilast 30 mg twice daily for 12 weeks, followed by an extension phase with all patients receiving apremilast through Week 64 and 4-week post-treatment follow-up (upon treatment discontinuation). The primary endpoint was area under the curve for the number of oral ulcers over 12 weeks (AUCWk0-12), reflecting the number of oral ulcers over time and accounting for their recurring-remitting course.

Disentanglement of Cape fur seals (Arctocephalus pusillus pusillus) with reversible medetomidine-midazolam-butorphanol.

Anaesthesia in pinnipeds is considered a much higher risk than in most terrestrial mammals because of their frequent proximity to water and physiological and anatomical adaptations related to diving, which also influence their anaesthesia management. Anaesthetising and immobilising entangled seals does not allow for selection of animals that are at a safe distance from the water's edge. Medetomidine-midazolam-butorphanol (MMB) sedation was trialled on eight entangled Cape fur seals (CFS) (Arctocephalus pusillus pusillus) to determine if it was safe to use on animals that entered the water post-darting.

ST8Sia6 Promotes Tumor Growth in Mice by Inhibiting Immune Responses.

Many tumors exhibit increased incorporation of sialic acids into cell-surface glycans, which impact the tumor microenvironment. Sialic acid immunoglobulin-like lectins (Siglec) are receptors that recognize sialic acids and modulate immune responses, including responses to tumors. However, the roles of individual sialyltransferases in tumorigenesis and tumor growth are not well understood.

Natural history of nasal vestibulitis associated with paclitaxel, docetaxel, and other chemotherapy agents: a Minnesota Cancer Clinical Trials Network (MNCCTN) study.

Purpose: To describe the natural history of nasal vestibulitis in patients receiving taxane chemotherapy, including incidence, severity, and associated symptoms.

Methods: Eligible patients with minimal or no baseline nasal symptoms were enrolled in this natural history study at initiation of a new chemotherapy regimen. Patients completed nasal symptom logs each time they received a chemotherapy dose.

A novel mathematical model of heterogeneous cell proliferation.

We present a novel mathematical model of heterogeneous cell proliferation where the total population consists of a subpopulation of slow-proliferating cells and a subpopulation of fast-proliferating cells. The model incorporates two cellular processes, asymmetric cell division and induced switching between proliferative states, which are important determinants for the heterogeneity of a cell population. As motivation for our model we provide experimental data that illustrate the induced-switching process.
