Improving Boron and Molybdenum Use Efficiencies in Contrasting Cultivars of Subirrigated Greenhouse-Grown Pot Chrysanthemums.

Fertilizer boron (B) and molybdenum (Mo) were provided to contrasting cultivars of subirrigated pot chrysanthemums at approximately 6-100% of current industry standards in an otherwise balanced nutrient solution during vegetative growth, and then all nutrients were removed during reproductive growth. Two experiments were conducted for each nutrient in a naturally lit greenhouse using a randomized complete block split-plot design. Boron (0.

Photographs and Parent Training to Support Conversations about Past Events between Caregivers and Children with Autism.

Objectives: Children with autism spectrum disorder experience communication difficulties that can make it challenging to engage in conversations. Their caregivers also often struggle with finding ways to support the child's communication. Parent-implemented interventions and visual supports are evidence-based practices to support the communication skills of children with autism.

Loneliness during COVID-19 and its association with eating habits and 24-hour movement behaviours in a sample of Canadian adolescents.

Loneliness, a feeling of distress, has aggravated due to the COVID-19 pandemic lockdowns and reduced social interactions. The objective of this study was to explore whether increased loneliness due to the COVID-19 pandemic was associated with various health behaviours in adolescence, a critical period for the development of lasting lifestyle habits. We used self-reported data from 40,521 Canadian adolescents aged 12-19 years (collected between November 2020 and June 2021) for this cross-sectional study.

ritical Care Cling to Improve ower xtremity Strength (CYCLE): protocol for an international, multicentre randomised clinical trial of early in-bed cycling for mechanically ventilated patients.

Introduction: In-bed leg cycling with critically ill patients is a promising intervention aimed at minimising immobility, thus improving physical function following intensive care unit (ICU) discharge. We previously completed a pilot randomised controlled trial (RCT) which supported the feasibility of a large RCT. In this report, we describe the protocol for an international, multicentre RCT to determine the effectiveness of early in-bed cycling versus routine physiotherapy (PT) in critically ill, mechanically ventilated adults.

Economic evaluation of tele-resuscitation intervention on emergency department pediatric visits in the Niagara Region, Canada a pilot study.

Introduction: The use of telemedicine in critical care is emerging, however, there is a paucity of information surrounding the costs relative to health gains in the pediatric population. This study aimed to estimate the cost-effectiveness of a pediatric tele-resuscitation (Peds-TECH) intervention compared to the usual care in five community hospital emergency departments (EDs). Using a decision tree analysis approach with secondary retrospective data from a 3-year time period, this cost-effectiveness analysis was completed.

Teaching with core concepts to facilitate the integrated learning of introductory organismal biology.

Despite the call from biology educators for students to learn the biological sciences as a unified whole, the teaching of introductory organismal biology is still largely arranged into separate sections that tend to focus exclusively on the biology of individual taxonomic categories (i.e., animals and plants).

Examining perceptions of a telemedicine network for pediatric emergency medicine: a mixed-methods pilot study.

Background: Use of telemedicine for healthcare delivery in the emergency department can increase access to specialized care for pediatric patients without direct access to a children's hospital. Currently, telemedicine is underused in this setting.

Objectives: This pilot research project aimed to evaluate the perceived effectiveness of a telemedicine program in delivering care to critically ill pediatric patients in the emergency department by exploring the experiences of parents/caregivers and physicians.

In silico induced effect of N-ε-lysine acetylation on microtubule stability and subsequent interaction of microtubule-associated proteins.

Plant systems have been considered valuable models for addressing fundamental questions of microtubule (MT) organization due to their considerable practical utility. Protein acetylation is a very common protein modification, and therate of acetylation can be modulated in cells in different biological states, and these changes can be detected at a molecular level. Here, we focused on K40, K112, and K394 residues as putative acetylation sites, which were shown to exist in both plants and mammals.

Spinal Cord Injury Community Personal Opinions and Perspectives on Spinal Cord Stimulation.

Background: Spinal cord stimulation (SCS) clinical trials are evaluating its efficacy and safety for motor, sensory, and autonomic recovery following spinal cord injury (SCI). The perspectives of people living with SCI are not well known and can inform the planning, delivery, and translation of SCS.

Objectives: To obtain input from people living with SCI on the top priorities for recovery, expected meaningful benefits, risk tolerance, clinical trial design, and overall interest in SCS.

Factors associated with Giardia infection in dogs in southern Ontario, Canada.

Information concerning risk factors associated with Giardia infection in dogs in southern Ontario, Canada, is currently lacking. This study therefore aimed to identify risk factors for Giardia infection in dogs that visit off-leash dog parks in southern Ontario. From May-November 2018, fecal samples were collected from 466 dogs in 12 off-leash dog parks in the Niagara and Hamilton regions of Ontario.

Adapting Our SCOPE: Lessons Learned from Spreading and Scaling Efforts to Integrate Care.

SCOPE (Seamless Care Optimizing the Patient Experience) launched in 2012 to support primary care in downtown Toronto with live navigation and rapid access to acute and community care resources for primary care providers (PCPs) and their patients. Ten years later, over 1,800 PCPs across Ontario have signed up for SCOPE and over 48,000 interactions in the form of e-mail, fax, phone and secure messaging have been conducted. Case examples illustrate the ways in which SCOPE has been adapted across a range of Ontario Health Teams, including under-resourced, small urban and rural sites.

A scoping review on the decision-making dynamics for accepting or refusing the COVID-19 vaccination among adolescent and youth populations.

Background: Global COVID-19 vaccinations rates among youth and adolescent populations prove that there is an opportunity to influence the acceptance for those who are unvaccinated and who are hesitant to receive additional doses. This study aimed to discover the acceptance and hesitancy reasons for choosing or refusing to be vaccinated against COVID-19.

Methods: A scoping review was conducted, and articles from three online databases, PubMed, Wiley, and Cochrane Library, were extracted and screened based on exclusion and PICOs criteria.

A propensity score-matched comparative study of balloon guide catheters versus conventional guide catheters for concurrent mechanical thrombectomy with carotid stenting in tandem strokes: comparison of first pass effect, symptomatic intracranial hemorrhage, and 90-day functional outcomes.

Background: Extensive clot burden in tandem strokes accounts for poor mechanical thrombectomy (MT) outcomes. Several studies have shown the benefit of balloon guide catheters (BGCs) in MT and carotid artery stenting.

Objective: In view of this potential benefit, to investigate the safety and effectiveness of proximal flow arrest using a BGC during concurrent MT and carotid revascularization for tandem stroke treatment in a comparative, propensity score-matched (PSM) study.

Embryo Loss and Moral Status.

There is a significant debate over the moral status of human embryos. This debate has important implications for practices like abortion and IVF. Some argue that embryos have the same moral status as infants, children, and adults.

Under pressure: What individual characteristics lead to performance of high-quality chest compressions during CPR practice sessions?

Aim: Despite well-established protocols for cardiopulmonary resuscitation training, performance during real-life cardiac arrests can be suboptimal. Understanding personal characteristics which could influence performance of high-quality chest compressions could provide insight into the practice-performance gap. This study examined chest compression performance, while employing feedback and introducing code team sounds as an anxiety-inducing factor in registered nurses using a cardiopulmonary resuscitation training manikin.

Interdisciplinary behavioral health provider perceptions of implementing the Collaborative Chronic Care Model: an i-PARIHS-guided qualitative study.

Background: The evidence-based Collaborative Chronic Care Model (CCM), developed to help structure care for chronic health conditions, comprises six elements: work role redesign, patient self-management support, provider decision support, clinical information systems, linkages to community resources, and organizational/leadership support. As the CCM is increasingly implemented in real-world settings, there is heightened interest in understanding specific influences upon implementation. Therefore, guided by the Integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework, we (i) identified innovation-, recipient-, context-, and facilitation-related influences on CCM implementation and (ii) assessed the influences' relationship to each CCM element's implementation.
