Process of development of decentralised clinical trial methodology for cancer clinical trials in Aotearoa New Zealand.

Aim: To develop processes for the development of decentralised clinical trial methodology for Aotearoa New Zealand, focussing on equity of access to cancer clinical trials for Māori, Pacific people, vulnerable communities and those in rural settings.

Methods: A national steering committee supported by Te Aho o Te Kahu - Cancer Control Agency was formed to: guide the adaptation and implementation of overseas decentralised clinical trial models to suit the needs of Aotearoa New Zealand with an equity focus; provide high-level oversight and expertise for direction and development of policies, procedures and infrastructure compliant with ICH GCP R2; and implement a national strategy.

Results: Twelve standard operating procedures were developed, as well as a supervision plan and a glossary.

The effects of isolated game elements on adherence rates in food response inhibition training.

Food response inhibition training (food-RIT) is found to aid weight loss and reduce snacking of foods high in sugar, salt and fat. However, these interventions suffer from a lack of adherence, with gamification proposed as a solution to increase engagement. The effect of gamification is unclear, however, with a lack of research investigating the effects of single game elements in improving adherence to interventions.

Inhibitory control training to reduce appetitive behaviour: a meta-analytic investigation of effectiveness, potential moderators, and underlying mechanisms of change.

Background/aims: Inhibitory control training (ICT) is a cognitive intervention that has been suggested to reduce problematic appetitive behaviours, such as unhealthy eating and excessive alcohol consumption. We conducted a meta-analytic review of ICT for reducing appetitive behaviours.

Methods: Two meta-analyses were conducted for behavioural (objective) outcomes and self-report outcomes, along with 14 moderator analyses, and two secondary analyses investigating changes in cue-devaluation and inhibitory control.

Exploring the Utility of Cell-Penetrating Peptides as Vehicles for the Delivery of Distinct Antimalarial Drug Cargoes.

The devastating impact of malaria includes significant mortality and illness worldwide. Increasing resistance of the causative parasite, Plasmodium, to existing antimalarial drugs underscores a need for additional compounds with distinct modes of action in the therapeutic development pipeline. Here we showcase peptide-drug conjugates (PDCs) as an attractive compound class, in which therapeutic or lead antimalarials are chemically conjugated to cell-penetrating peptides.

Dose-fractionation studies of a phosphatidylinositol 4-kinase inhibitor in a humanized mouse model of malaria.

UCT594 is a 2-aminopyrazine carboxylic acid phosphatidylinositol 4-kinase inhibitor with potent asexual blood-stage activity, the potential for interrupting transmission, as well as liver-stage activities. Herein, we investigated pharmacokinetic/pharmacodynamic (PK/PD) relationships relative to blood-stage activity toward predicting the human dose. Dose-fractionation studies were conducted in the NSG mouse model to determine the PK/PD indices of UCT594, using the minimum parasiticidal concentration as a threshold.

Accelerating AI for science: open data science for science.

Aspirations for artificial intelligence (AI) as a catalyst for scientific discovery are growing. High-profile successes deploying AI in domains such as protein folding have highlighted AI's potential to unlock new frontiers of scientific knowledge. However, the pathway from AI innovation to deployment in research is not linear.

Enhancing the Intrinsic Antiplasmodial Activity and Improving the Stability and Selectivity of a Tunable Peptide Scaffold Derived from Human Platelet Factor 4.

The control of malaria, a disease caused by parasites that kills over half a million people every year, is threatened by the continual emergence and spread of drug resistance. Therefore, new molecules with different mechanisms of action are needed in the antimalarial drug development pipeline. Peptides developed from host defense molecules are gaining traction as anti-infectives due to theood of inducing drug resistance.

An Update on Cutaneous Angiosarcoma Diagnosis and Treatment.

Cutaneous angiosarcoma (CAS) is a rare aggressive malignancy that most commonly manifests in White men older than 60 years and often appears as an enlarging ecchymosis on the head, neck, or scalp. Surgery with negative margins is the first-line treatment. The role of Mohs micrographic surgery (MMS) is uncertain but can be used in smaller, well-circumscribed lesions on the head and neck.

Cyclic tachyplesin I kills proliferative, non-proliferative and drug-resistant melanoma cells without inducing resistance.

Acquired drug resistance is the major cause for disease recurrence in cancer patients, and this is particularly true for patients with metastatic melanoma that carry a BRAF mutation. To address this problem, we investigated cyclic membrane-active peptides as an alternative therapeutic modality to kill drug-tolerant and resistant melanoma cells to avoid acquired drug resistance. We selected two stable cyclic peptides (cTI and cGm), previously shown to have anti-melanoma properties, and compared them with dabrafenib, a drug used to treat cancer patients with the BRAF mutation.

Mechanisms underlying episodic nitrate and phosphorus leaching from poorly drained agricultural soils.

Poorly drained depressions within tile-drained croplands can have disproportionate environmental and agronomic impacts, but mechanisms controlling nutrient leaching remain poorly understood. We monitored nitrate and soluble reactive phosphorus (SRP) leaching using zero-tension soil lysimeters across a depression to upland gradient over 2 years in a corn-soybean (Zea mays L.-Glycine max [L.

Identification of ATP-Competitive Human CMG Helicase Inhibitors for Cancer Intervention that Disrupt CMG-Replisome Function.

The human CMG helicase (Cdc45-MCM-GINS) is a novel target for anticancer therapy. Tumor-specific weaknesses in the CMG are caused by oncogene-driven changes that adversely affect CMG function, and CMG activity is required for recovery from replicative stresses such as chemotherapy. Herein, we developed an orthogonal biochemical screening approach and identified CMG inhibitors (CMGi) that inhibit ATPase and helicase activities in an ATP-competitive manner at low micromolar concentrations.

Quitting intentions and behaviours among young Australian e-cigarette users.

Background And Aims: With the prevalence of e-cigarette use among Australian youth increasing significantly in recent years, greater attention is being paid to encouraging and supporting cessation. However, research to inform such efforts is lacking. The present study sought to (i) measure desire to quit e-cigarette use and actual quitting attempts among young Australians and (ii) explore correlates of quitting-related cognitions and behaviours.

Repurposing a plant peptide cyclase for targeted lysine acylation.

Transpeptidases are powerful tools for protein engineering but are largely restricted to acting at protein backbone termini. Alternative enzymatic approaches for internal protein labelling require bulky recognition motifs or non-proteinogenic reaction partners, potentially restricting which proteins can be modified or the types of modification that can be installed. Here we report a strategy for labelling lysine side chain ε-amines by repurposing an engineered asparaginyl ligase, which naturally catalyses peptide head-to-tail cyclization, for versatile isopeptide ligations that are compatible with peptidic substrates.

Fall prevention in a pediatric unit: a best practice implementation project.

Introduction: Inpatient falls account for 6% to 24% of pediatric safety incidents and can lead to increased length of hospital stay, increased cost of care, and decreased satisfaction with care. A review of a pediatric hematology, oncology, neurology, and rehabilitation unit in a hospital in the southern United States revealed an average of one to two falls monthly.

Objective: This project aimed to promote evidence-based practices (EBPs) regarding fall prevention in the pediatric unit.

Methods: A national service evaluation using online questionnaires circulated to patients and clinicians from secondary and tertiary UK centres managing CYP with CAH, and via the "Living with CAH" support group mailing list.

Results: Total of 195 responses relating to patients aged 0-20 years attending 33 clinics (43 patients, 152 carers), as well as 34 clinicians from 18 trusts working across the 33 clinics.

Preparation and investigation of two-component silica-modified hydrophobic layer for minimizing retention loss of reversed-phase chromatographic columns using fully aqueous mobile phases.

Chromatographers often employ fully aqueous mobile phases to retain highly polar compounds in reversed-phase liquid chromatography (RPLC). However, when the flow rate is interrupted, either accidentally or intentionally, a substantial loss in retention occurs due to the spontaneous dewetting of water from the hydrophobic surface of conventional RPLC-C particles. Previous studies have shown that maintaining a low C surface coverage (approximately 1.

PAM trial protocol: a randomised feasibility study of psychedelic microdosing-assisted meaning-centred psychotherapy in advanced stage cancer patients.

Background: An advanced cancer diagnosis can be associated with a significant profile of distress. Psychedelic compounds have shown clinically significant effects in the treatment of psychological distress in patients with advanced-stage cancer. Given the challenges of delivering timely and effective intervention in the advanced cancer context, it is possible that an alternative, more pragmatic, approach lies in psychedelic 'microdosing'.

Methods: Two outcome measures and five process measures were identified.

Bacterial Organisms Colonizing Mohs Surgical Wounds Healing by Second Intention on the Lower Extremities: A Prospective, Controlled Study.

Background: Based on recent research, second intention wounds may be at greater risk for postoperative infection compared with sutured wounds. Accurate diagnosis of postoperative wound infections on the lower leg can be challenging and result in unnecessary antibiotic administration.

Objective: The objective of this study was to identify bacterial organisms that commonly colonize second intention surgical wounds after Mohs micrographic surgery (MMS) and isolate pathogenic organisms.

"It helps me to stay on the right path, rather than give in": Mixed-method process evaluation of the ImpulsePal app-based intervention for weight management.

Background: Empirical research indicates that impulsive processes that operate below conscious monitoring can undermine peoples' attempts to change behaviour patterns, especially those that have become habitual. This may, therefore, be a serious challenge for those trying to lose weight. A novel smartphone app-based intervention (ImpulsePal) offers practical strategies to manage impulsive urges to facilitate reductions in the consumption of energy-dense processed food and overeating.
