The progression of type II diabetes (T2D) is characterized by a complex and highly variable loss of beta-cell mass, resulting in impaired insulin secretion. Many T2D drug discovery efforts aimed at discovering molecules that can protect or restore beta-cell mass and function have been developed using limited beta-cell lines and primary rodent/human pancreatic islets. Various high-throughput screening methods have been used in the context of drug discovery, including luciferase-based reporter assays, glucose-stimulated insulin secretion, and high-content screening...

BACKGROUND: Population-level administrative data provides a cost-effective means of monitoring health outcomes and service needs of clinical populations. This study aimed to present a method for case identification of non-traumatic brain injury in population-level data and to examine the association with sociodemographic factors. METHODS: An estimated resident population of youth aged 0-24 years was constructed using population-level datasets within the New Zealand Integrated Data Infrastructure...

The recent COVID-19 outbreak highlighted the need for lab-on-chip diagnostic technology fit for real-life deployment in the field. Existing bottlenecks in multistep analytical microsystem integration and upscalable, standardized fabrication techniques delayed the large-scale deployment of lab-on-chip solutions during the outbreak, throughout a global diagnostic test shortage. This study presents a technology that has the potential to address these issues by redeploying and repurposing the ubiquitous printed circuit board (PCB) technology and manufacturing infrastructure...

Diabetes poses a global health crisis affecting individuals across age groups and backgrounds, with a prevalence estimate of 700 million people worldwide by 2045. Current therapeutic strategies primarily rely on insulin therapy or hypoglycemic agents, which fail to address the root cause of the disease - the loss of pancreatic insulin-producing beta-cells. Therefore, bioassays that recapitulate intact islets are needed to enable drug discovery for beta-cell replenishment, protection from beta-cell loss, and islet-cell interactions...

OBJECTIVE: To examine criminal justice system (CJS) interactions and pathways through the justice system for young adults with ADHD compared to young adults without ADHD. METHOD: Nationwide 3-year birth cohort study using linked health and CJS data. Cox proportional hazards models were employed to examine associations between ADHD and police proceedings, court charges, court convictions, and incarcerations. RESULTS: Young adults with ADHD were significantly more likely to interact with the CJS including police proceedings (hazard ratio [HR], 2...

BACKGROUND: Childhood traumatic brain injury (TBI) can result in impairments in learning, cognition, and behaviour; all of which can adversely influence educational outcomes. Schools can play a crucial role in rehabilitation, therefore it is important that evidence-based supports are available in these settings. OBJECTIVE: The aim of this systematic review was to evaluate the effectiveness of school-based supports and interventions available following childhood TBI...

Mitosis is the cellular process that ensures accurate segregation of the cell's genetic material into two daughter cells. Mitosis is often deregulated in cancer, thus drugs that target mitosis-specific proteins represent attractive targets for anticancer therapy. Numerous inhibitors have been developed against kinesin-5 Eg5, a kinesin essential for bipolar spindle assembly. Unfortunately, Eg5 inhibitors (K5Is) have been largely ineffective in the clinic, possibly due to the activity of a second kinesin, KIF15, that can suppress the cytotoxic effect of K5Is by driving spindle assembly through an Eg5-independent pathway...

Traumatic brain injury (TBI) has the highest incidence of all common neurological disorders, and poses a substantial public health burden. TBI is increasingly documented not only as an acute condition but also as a chronic disease with long-term consequences, including an increased risk of late-onset neurodegeneration. The first Lancet Neurology Commission on TBI, published in 2017, called for a concerted effort to tackle the global health problem posed by TBI. Since then, funding agencies have supported research both in high-income countries (HICs) and in low-income and middle-income countries (LMICs)...

Niclosamide, an FDA-approved oral anthelmintic drug, has broad biological activity including anticancer, antibacterial, and antiviral properties. Niclosamide has also been identified as a potent inhibitor of SARS-CoV-2 infection in vitro, generating interest in its use for the treatment or prevention of COVID-19. Unfortunately, there are several potential issues with using niclosamide for COVID-19, including low bioavailability, significant polypharmacology, high cellular toxicity, and unknown efficacy against emerging SARS-CoV-2 variants of concern...

Recent research has highlighted that a high prevalence of young adults who have various forms of neurodivergence come into contact with the criminal justice system. Currently, many courts are not designed to respond to neurological differences often seen in young people who engage with them. The aim of this study was to identify ways to make locality courts more accessible, engaging, and ultimately more responsive to neurodivergence. A panel of neurodivergence specialists reviewed the general district courtroom environment of a new specialised young adult list court in Aotearoa New Zealand to identify potential barriers to accessibility and to highlight areas for improvement...

Researchers around the world have demonstrated correlations between measurements of SARS-CoV-2 RNA in wastewater (WW) and case rates of COVID-19 derived from direct testing of individuals. This has raised concerns that wastewater-based epidemiology (WBE) methods might be used to quantify the spread of this and other diseases, perhaps faster than direct testing, and with less expense and intrusion. We illustrate, using data from Scotland and the USA, the issues regarding the construction of effective predictive models for disease case rates...

Sensationalist headlines and highly publicised criminal cases lead many in the public to believe that people with autism are more likely to engage in criminal behaviour. However, recent studies present an unresolved debate, and indicate this may not necessarily be the case. The aims of this study were to examine the prevalence of criminal justice system interactions among young adults with and without autism, and determine whether offence types differ between these groups. We tracked a national birth cohort until their 25th birthday, detecting criminal justice system interactions from age 17 onwards...

Healthcare organizations have prioritized patient safety and quality improvement efforts to reduce central line-associated bloodstream infections (CLABSIs). Implementation of central venous catheter (CVC) insertion and maintenance bundles have significantly reduced infection rates. Nevertheless, CLABSIs continue to be a significant cause of mortality and morbidity in hospitals, and further efforts are necessary to improve CVC care practices. A hospital-wide committee at a tertiary care pediatric hospital identified gaps in our CVC maintenance practices resulting from CVC contamination events from a patient's body fluids...

Exophiala dermatitidis is a dematiaceous fungus with yeast-like and hyphal growth states that may cause cutaneous and visceral infections. Recently, E. dermatitidis has been linked to central line associated blood stream infection (CLABSI), probably due to its ability to produce extracellular polysaccharides and grow as biofilm. We describe an E. dermatitidis CLASBI. The strain was identified by morphological and molecular methods. E. dermatitidis CLASBI is highly uncommon, but seems to be increasing.

A new class of hepatitis C NS3/4A inhibitors was identified by introducing a novel spirocyclic proline-P2 surrogate onto the P2-P4 macrocyclic core of MK-5172 (grazoprevir). The potency profile of new analogues showed excellent pan-genotypic activity for most compounds. The potency evaluation included the most difficult genotype 3a (EC50 values ≤10 nM) and other key genotype 1b mutants. Molecular modeling was used to design new target compounds and rationalize our results. A synthetic approach based on the Julia-Kocienski olefination and macrolactamization to assemble the P2-P4 macrocyclic core containing the novel spirocyclic proline-P2 moiety is presented as well...
