MAiD to Last: Creating a Care Ecology for Sustainable Medical Assistance in Dying Services.

This paper depicts a case study of an organizational strategy for the promotion of ethical practice when introducing a new, high-risk, ethically-charged medical practice like Medical Assistance in Dying (MAiD). We describe the development of an interprofessional program that enables the delivery of high-quality, whole-person MAiD care that is values-based and sustainable. A "care ecology" strategy recognizes the interconnected web of relationships and structures necessary to support a quality experience of MAiD for patients, families, and clinicians.

Introducing Medical Assistance in Dying in Canada: Lessons on Pragmatic Ethics and the Implementation of a Morally Contested Practice.

Medical Assistance in Dying (MAiD) in Canada has had a tumultuous social and legal history. In the 6 years since assisted dying was decriminalized by the Canadian Parliament in June 2016, the introduction of this practice into the Canadian healthcare system has been fraught with ethical challenges, practical hurdles and grass-roots innovation. In 2021, MAiD accounted for approximately 3.

Access Isn't Enough: Evaluating the Quality of a Hospital Medical Assistance in Dying Program.

Following an initial study of the needs of healthcare providers (HCP) regarding the introduction of Medical Assistance in Dying (MAiD), and the subsequent development of an assisted dying program, this study sought to determine the efficacy and impact of MAiD services following the first two years of implementation. The first of three aims of this research was to understand if the needs, concerns and hopes of stakeholders related to patient requests for MAiD were addressed appropriately. Assessing how HCPs and families perceived the quality of MAiD services, and determining if the program successfully accommodated the diverse needs and perspectives of HCPs, rounded out this quality evaluation.

Double-edged MAiD death family legacy: a qualitative descriptive study.

Background: Individuals who accompany a loved one through medical assistance in dying (MAiD) have to live with the experience and the psychological, moral and social consequences of their involvement in the process long after the death occurs.

Aim: To explore the legacy of a MAiD death for individuals who accompanied a loved one through the process.

Design: Using a qualitative descriptive approach we conducted semi-structured interviews to collect data from family members who had accompanied a loved one through MAiD.

Pigment Dispersing Factors and Their Cognate Receptors in a Crustacean Model, With New Insights Into Distinct Neurons and Their Functions.

Pigment dispersing factors (PDFs, or PDHs in crustaceans) form a structurally related group of neuropeptides found throughout the Ecdysozoa and were first discovered as pigmentary effector hormones in crustaceans. In insects PDFs fulfill crucial neuromodulatory roles, most notably as output regulators of the circadian system, underscoring their central position in physiological and behavioral organization of arthropods. Intriguingly, decapod crustaceans express multiple isoforms of PDH originating from separate genes, yet their differential functions are still to be determined.

Becoming a medical assistance in dying (MAiD) provider: an exploration of the conditions that produce conscientious participation.

The availability of willing providers of medical assistance in dying (MAiD) in Canada has been an issue since a Canadian Supreme Court decision and the subsequent passing of federal legislation, Bill C14, decriminalised MAiD in 2016. Following this legislation, Hamilton Health Sciences (HHS) in Ontario, Canada, created a team to support access to MAiD for patients. This research used a qualitative, mixed methods approach to data collection, obtaining the narratives of providers and supporters of MAiD practice at HHS.

Transcriptomic characterisation of neuropeptides and their putative cognate G protein-coupled receptors during late embryo and stage-1 juvenile development of the Aotearoa-New Zealand crayfish, Paranephrops zealandicus.

We de novo assembled a transcriptome for early life-stages of the Aotearoa-New Zealand crayfish, Paranephrops zealandicus, establishing the first genetic resource for this under-developed aquaculture species and for the Paranephrops genus. Mining of this transcriptome for neuropeptides and their putative cognate G protein-coupled receptors (GPCRs) yielded a comprehensive catalogue of neuropeptides, but few putative neuropeptide GPCRs. Of the neuropeptides commonly identified from decapod transcriptomes, only crustacean female sex hormone and insulin-like peptide were absent from our trinity de novo transcriptome assembly, and also RNA-sequence reads.

Proteogenomic Characterization of Endometrial Carcinoma.

We undertook a comprehensive proteogenomic characterization of 95 prospectively collected endometrial carcinomas, comprising 83 endometrioid and 12 serous tumors. This analysis revealed possible new consequences of perturbations to the p53 and Wnt/β-catenin pathways, identified a potential role for circRNAs in the epithelial-mesenchymal transition, and provided new information about proteomic markers of clinical and genomic tumor subgroups, including relationships to known druggable pathways. An extensive genome-wide acetylation survey yielded insights into regulatory mechanisms linking Wnt signaling and histone acetylation.

Comparative transcriptomic analysis of a wing-dimorphic stonefly reveals candidate wing loss genes.

Background: The genetic basis of wing development has been well characterised for model insect species, but remains poorly understood in phylogenetically divergent, non-model taxa. Wing-polymorphic insect species potentially provide ideal systems for unravelling the genetic basis of secondary wing reduction. Stoneflies (Plecoptera) represent an anciently derived insect assemblage for which the genetic basis of wing polymorphism remains unclear.

Arabidopsis thaliana organelles mimic the T7 phage DNA replisome with specific interactions between Twinkle protein and DNA polymerases Pol1A and Pol1B.

Background: Plant chloroplasts and mitochondria utilize nuclear encoded proteins to replicate their DNA. These proteins are purposely built for replication in the organelle environment and are distinct from those involved in replication of the nuclear genome. These organelle-localized proteins have ancestral roots in bacterial and bacteriophage genes, supporting the endosymbiotic theory of their origin.

Transcriptomic analysis of crustacean neuropeptide signaling during the moult cycle in the green shore crab, Carcinus maenas.

Background: Ecdysis is an innate behaviour programme by which all arthropods moult their exoskeletons. The complex suite of interacting neuropeptides that orchestrate ecdysis is well studied in insects, but details of the crustacean ecdysis cassette are fragmented and our understanding of this process is comparatively crude, preventing a meaningful evolutionary comparison. To begin to address this issue we identified transcripts coding for neuropeptides and their putative receptors in the central nervous system (CNS) and Y-organs (YO) within the crab, Carcinus maenas, and mapped their expression profiles across accurately defined stages of the moult cycle using RNA-sequencing.

Functional Identification and Characterization of the Diuretic Hormone 31 (DH31) Signaling System in the Green Shore Crab, .

The functional characterization of crustacean neuropeptides and their cognate receptors has not kept pace with the recent advances in sequence determination and, therefore, our understanding of the physiological roles of neuropeptides in this important arthropod sub-phylum is rather limited. We identified a candidate receptor-ligand pairing for diuretic hormone 31 (DH31) in a neural transcriptome of the crab, . In insects, DH31 plays species -specific but central roles in many facets of physiology, including fluid secretion, myoactivity, and gut peristalsis but little is known concerning its functions in crustaceans.

Plasmonic Sensor Could Enable Label-Free DNA Sequencing.

We demonstrated a proof-of-principle concept of a label-free platform that enables nucleic acid sequencing by binding methodology. The system utilizes gold surfaces having high fidelity plasmonic nanohole arrays which are very sensitive to minute changes of local refractive indices. Our novel surface chemistry approach ensures accurate identification of correct bases at individual positions along a targeted DNA sequence on the gold surface.

Functional Characterization and Signaling Systems of Corazonin and Red Pigment Concentrating Hormone in the Green Shore Crab, .

Neuropeptides play a central role as neurotransmitters, neuromodulators and hormones in orchestrating arthropod physiology. The post-genomic surge in identified neuropeptides and their putative receptors has not been matched by functional characterization of ligand-receptor pairs. Indeed, until very recently no G protein-coupled receptors (GPCRs) had been functionally defined in any crustacean.

Identifying Robertsonian Translocation Carriers by Microarray-Based DNA Analysis.

Objective: To develop a noninvasive prenatal testing improvement that allows identification of Robertsonian translocation carriers.

Methods: Blood samples from 191 subjects, including 7 pregnant and 9 non-pregnant Robertsonian translocation carriers, were analyzed for fetal trisomy and Robertsonian translocation status. Digital Analysis of Selected Regions (DANSR™) assays targeting sequences common to the p arms of 5 acrocentric chromosomes were developed and added to existing DANSR assays.

The potential for climate-driven bathymetric range shifts: sustained temperature and pressure exposures on a marine ectotherm, Palaemonetes varians.

Range shifts are of great importance as a response for species facing climate change. In the light of current ocean-surface warming, many studies have focused on the capacity of marine ectotherms to shift their ranges latitudinally. Bathymetric range shifts offer an important alternative, and may be the sole option for species already at high latitudes or those within enclosed seas; yet relevant data are scant.

Reconstructing disturbance history for an intensively mined region by time-series analysis of Landsat imagery.

Surface mining disturbances have attracted attention globally due to extensive influence on topography, land use, ecosystems, and human populations in mineral-rich regions. We analyzed a time series of Landsat satellite imagery to produce a 28-year disturbance history for surface coal mining in a segment of eastern USA's central Appalachian coalfield, southwestern Virginia. The method was developed and applied as a three-step sequence: vegetation index selection, persistent vegetation identification, and mined-land delineation by year of disturbance.

Microarray-based cell-free DNA analysis improves noninvasive prenatal testing.

Objective: To develop a microarray-based method for noninvasive prenatal testing (NIPT) and compare it with next-generation sequencing.

Methods: Maternal plasma from 878 pregnant women, including 187 trisomy cases (18 trisomy 13, 37 trisomy 18, 132 trisomy 21), was evaluated for trisomy risk. Targeted chromosomes were analyzed using Digital Analysis of Selected Regions (DANSR™) assays.

Non-invasive risk assessment of fetal sex chromosome aneuploidy through directed analysis and incorporation of fetal fraction.

Objective: To assess the performance of a directed chromosomal analysis approach in the prenatal evaluation of fetal sex chromosome aneuploidy.

Methods: We analyzed 432 frozen maternal plasma samples obtained from patients prior to undergoing fetal diagnostic testing. The cohort included women greater than 18 years of age with a singleton pregnancy of greater than 10 weeks gestation.

Fetal fraction estimate in twin pregnancies using directed cell-free DNA analysis.

Objective: To estimate fetal fraction (FF) in monozygotic and dizygotic twin pregnancies.

Methods: Maternal plasma samples were obtained from 35 monochorionic twin pregnancies with male fetuses (monozygotic) and 35 dichorionic pregnancies discordant for fetal sex (dizygotic) at 11-13 weeks' gestation. Cell-free DNA was extracted and chromosome-selective sequencing with digital analysis of selected regions (DANSR™) was carried out.

The implications of temperature-mediated plasticity in larval instar number for development within a marine invertebrate, the shrimp Palaemonetes varians.

Variations in larval instar number are common among arthropods. Here, we assess the implications of temperature-mediated variations in larval instar number for larval development time, larval growth rates, and juvenile dry weight within the palaemonid shrimp, Palaemonetes varians. In contrast with previous literature, which focuses on terrestrial arthropods, particularly model and pest species often of laboratory lines, we use wild shrimp, which differ in their life history from previous models.
