Establishing a Community of Practice for Doctoral Studies Amidst the COVID-19 Pandemic

In this discussion paper, we describe our experience completing the first year of the doctorate in nursing program at a large urban academic centre during the COVID-19 pandemic. We highlight the current nursing shortage and the importance of supporting all nursing students, including nurses in doctoral programs, towards successful graduation. We describe the development of a virtual community of practice incorporating five key strategies: Building community, fostering collaboration, strengthening connection, enhancing creativity, and promoting consistency. We believe that utilizing these strategies will contribute to our success and may be relevant to nursing leaders seeking to support the development of more doctorally prepared nurses. Participation in a community of practice early on in doctoral education will not only better prepare students for success in their program, but also continued success as they progress through their careers. It is important for students to not only make connections with peers in their area of academic study, but to also reach out to peers in other disciplines to improve both individual and interdisciplinary growth. Program administrators and educators can encourage the formation of community of practice among novice doctoral students. This encouragement can be achieved using a virtual platform, or in-person networking opportunities. Inviting incoming graduate students to connect with each other and with students from previous cohorts also fosters community of practice formation. Résumé Dans ce texte de discussion, nous décrivons notre expérience relative à la première année du doctorat en sciences infirmières dans un grand centre universitaire urbain pendant la pandémie de COVID-19. Nous soulignons la pénurie actuelle d’infirmières et l’importance de soutenir toutes les étudiantes en sciences infirmières, y compris les infirmières inscrites à un programme de doctorat, vers la réussite de leurs études. Nous décrivons le développement d’une communauté virtuelle de pratique intégrant cinq stratégies clés : créer une communauté, favoriser la collaboration, renforcer les liens, mettre en valeur la créativité et promouvoir la cohérence. Nous pensons que l’utilisation de ces stratégies contribuera à notre succès et pourrait être pertinente pour les infirmières chefs de file qui cherchent à soutenir le développement d’un plus grand nombre d’infirmières préparées au doctorat. La participation à une communauté de pratique dès le début de la formation doctorale permettra non seulement de mieux préparer les étudiantes à réussir dans leur programme, mais favorisera également leur poursuite d’une carrière fructueuse. Il est important pour les étudiantes d’établir des liens non seulement avec des pairs dans leur domaine d’études universitaires, mais qu’ils entrent également en contact avec des pairs d’autres disciplines pour améliorer à la fois leur croissance individuelle et interdisciplinaire. Les administratrices de programme et les enseignantes peuvent encourager la formation d’une communauté de pratique parmi les doctorantes novices. Cet encouragement peut être réalisé à l’aide d’une plateforme virtuelle ou d’occasions de réseautage en personne. Inviter les étudiantes diplômées à entrer en contact les unes avec les autres et avec les étudiantes des cohortes précédentes favorise également la formation d’une communauté de pratique

A community of practice for graduate students in health sciences

Purpose – The aim of this study was to describe the experiences of graduate students who participated in the community of practice (CoP) and identify areas for improvement to support academic success. Design/methodology/approach – In total, 19 graduate students engaged in a CoP to facilitate social interactions, knowledge sharing and learning within a culture of scholarship. A descriptive qualitative research study was conducted using semistructured interviews with eight participants who had attended the CoP meeting. Findings – All participants were from the School of Nursing and perceived the CoP to be beneficial, particularly international students who had challenges in adapting to new academic and social environments. Areas for improvement include creating a group structure that enhances belonging and learning. Originality/value – This is the first CoP that was implemented at the Faculty of Health Sciences at the authors’ university. It has been the authors’ experience that a CoP can benefit graduate students through networking, knowledge sharing, social support and learning. The finding of this research will be used to inform a new CoP to address the needs of graduate students. The authors will be adapting the CoP to the current context that includes a virtual platform during the COVID-19 pandemic and will include content specific for international students

Phosphodiesterase 10A Upregulation Contributes to Pulmonary Vascular Remodeling

Phosphodiesterases (PDEs) modulate the cellular proliferation involved in the pathophysiology of pulmonary hypertension (PH) by hydrolyzing cAMP and cGMP. The present study was designed to determine whether any of the recently identified PDEs (PDE7-PDE11) contribute to progressive pulmonary vascular remodeling in PH. All in vitro experiments were performed with lung tissue or pulmonary arterial smooth muscle cells (PASMCs) obtained from control rats or monocrotaline (MCT)-induced pulmonary hypertensive (MCT-PH) rats, and we examined the effects of the PDE10 inhibitor papaverine (Pap) and specific small interfering RNA (siRNA). In addition, papaverine was administrated to MCT-induced PH rats from day 21 to day 35 by continuous intravenous infusion to examine the in vivo effects of PDE10A inhibition. We found that PDE10A was predominantly present in the lung vasculature, and the mRNA, protein, and activity levels of PDE10A were all significantly increased in MCT PASMCs compared with control PASMCs. Papaverine and PDE10A siRNA induced an accumulation of intracellular cAMP, activated cAMP response element binding protein and attenuated PASMC proliferation. Intravenous infusion of papaverine in MCT-PH rats resulted in a 40%–50% attenuation of the effects on pulmonary hypertensive hemodynamic parameters and pulmonary vascular remodeling. The present study is the first to demonstrate a central role of PDE10A in progressive pulmonary vascular remodeling, and the results suggest a novel therapeutic approach for the treatment of PH

A Locus on Mouse Chromosome 6 That Determines Resistance to Herpes Simplex Virus Also Influences Reactivation, While an Unlinked Locus Augments Resistance of Female Mice

During studies to determine a role for tumor necrosis factor (TNF) in herpes simplex virus type 1 (HSV-1) infection using TNF receptor null mutant mice, we discovered a genetic locus, closely linked to the TNF p55 receptor (Tnfrsf1a) gene on mouse chromosome 6 (c6), that determines resistance or susceptibility to HSV-1. We named this locus the herpes resistance locus, Hrl, and showed that it also mediates resistance to HSV-2. Hrl has at least two alleles, Hrl(r), expressed by resistant strains like C57BL/6 (B6), and Hrl(s), expressed by susceptible strains like 129S6 (129) and BALB/c. Although Hrl is inherited as an autosomal dominant gene, resistance to HSV-1 is strongly sex biased such that female mice are significantly more resistant than male mice. Analysis of backcrosses between resistant B6 and susceptible 129 mice revealed that a second locus, tentatively named the sex modifier locus, Sml, functions to augment resistance of female mice. Besides determining resistance, Hrl is one of several genes involved in the control of HSV-1 replication in the eye and ganglion. Remarkably, Hrl also affects reactivation of HSV-1, possibly by interaction with some unknown gene(s). We showed that Hrl is distinct from Cmv1, the gene that determines resistance to murine cytomegalovirus, which is encoded in the major NK cell complex just distal of p55 on c6. Hrl has been mapped to a roughly 5-centimorgan interval on c6, and current efforts are focused on obtaining a high-resolution map for Hrl

Cannabis use in pregnancy and maternal and infant outcomes: a Canadian cross-jurisdictional population-based cohort study.

BACKGROUND: With the recent legalization of cannabis in Canada, there is an urgent need to understand the effect of cannabis use in pregnancy. Our population-based study investigated the effects of prenatal cannabis use on maternal and newborn outcomes, and modification by infant sex. METHODS: The cohort included 1,280,447 singleton births from the British Columbia Perinatal Data Registry, the Better Outcomes Registry & Network Ontario, and the Perinatal Program Newfoundland Labrador from April 1st, 2012 to March 31st, 2019. Logistic regression determined the associations between prenatal cannabis use and low birth weight, small-for-gestational age, large-for-gestational age, spontaneous and medically indicated preterm birth, very preterm birth, stillbirth, major congenital anomalies, caesarean section, gestational diabetes and gestational hypertension. Models were adjusted for other substance use, socio-demographic and-economic characteristics, co-morbidities. Interaction terms were included to investigate modification by infant sex. RESULTS: The prevalence of cannabis use in our cohort was approximately 2%. Prenatal cannabis use is associated with increased risks of spontaneous and medically indicated preterm birth, very preterm birth, low birth weight, small-for-gestational age and large-for-gestational age, any major congenital anomaly, caesarean section, and gestational diabetes. No association was found for stillbirth or gestational hypertension. Only small-for-gestational age (p = 0.03) and spontaneous preterm birth (p = 0.04) showed evidence of modification by infant sex. CONCLUSIONS: Prenatal cannabis use increases the likelihood of preterm birth, low birth weight, small-for-gestational age and major congenital anomalies with prenatally exposed female infants showing evidence of increased susceptibility. Additional measures are needed to inform the public and providers of the inherent risks of cannabis exposure in pregnancy

Current methods for the isolation of extracellular vesicles

Extracellular vesicles (EVs), including microvesicles and exosomes, are nano- to micron-sized vesicles, which may deliver bioactive cargos that include lipids, growth factors and their receptors, proteases, signaling molecules, as well as mRNA and non-coding RNA, released from the cell of origin, to target cells. EVs are released by all cell types and likely induced by mechanisms involved in oncogenic transformation, environmental stimulation, cellular activation, oxidative stress, or death. Ongoing studies investigate the molecular mechanisms and mediators of EVs-based intercellular communication at physiological and oncogenic conditions with the hope of using this information as a possible source for explaining physiological processes in addition to using them as therapeutic targets and disease biomarkers in a variety of diseases. A major limitation in this evolving discipline is the hardship and the lack of standardization for already challenging techniques to isolate EVs. Technical advances have been accomplished in the field of isolation with improving knowledge and emerging novel technologies, including ultracentrifugation, microfluidics, magnetic beads and filtration-based isolation methods. In this review, we will discuss the latest advances in methods of isolation methods and production of clinical grade EVs as well as their advantages and disadvantages, and the justification for their support and the challenges that they encounter
