Article Synopsis
  • The study presents a method to create stable suspension cell lines from 293T cells that produce lentiviral vectors using a single DNA construct, which simplifies the production process compared to the traditional method involving multiple plasmids.
  • These new cell lines can achieve high yields comparable to those from transient transfection and are designed to be easily scaled up in bioreactors, promoting efficient large-scale production.
  • By streamlining the production process and improving stability and yield, this approach aims to enhance patient access to therapies developed using lentiviral vectors.

Despite a growing policy push for the provision of services based on evidence, evidence-based treatments for children and youth with mental health challenges have poor uptake, yielding limited benefit. With a view to improving implementation in child behavioral health, we investigated a complementary implementation approach informed by three implementation frameworks in the context of implementing motivational interviewing in four child and youth behavioral health agencies: the Active Implementation Frameworks (AIF) (process), the Consolidated Framework for Implementation Research (factors), and the Implementation Outcomes Framework (evaluation). The study design was mixed methods with embedded interrupted time series and motivational interviewing (MI) fidelity was the primary outcome.

Despite the emerging literature documenting gains in clinician competence following consultation, little empirical work has examined consultation as an implementation strategy. To this end, the present study examined consultation in the context of implementing motivational interviewing in four community child and youth mental health organizations. We used qualitative methods with a dual goal: to describe the consultation process and to explore trainees' perspectives on consultation.

Lentiviral vectors (LVs) have been successfully used in clinical trials showing long term therapeutic benefits. Studying the role of cellular proteins in lentivirus HIV-1 life cycle can help understand virus assembly and budding, leading to improvement of LV production for gene therapy. Lentiviral vectors were purified using size exclusion chromatography (SEC).

Background: The purpose of this study was to compare the effectiveness of QuikClot(®) Combat Gauze™ (QCG) to a control wound dressing to withstand movement in a porcine model with hemodilution and hypothermia.

Design: This was a prospective study with a between-subjects experimental design. Twenty-six Yorkshire swine were randomly assigned to two groups: QCG (n = 13) or a control dressing (n = 13).

This prospective, experimental, mixed study determined whether there were differences in intraosseous (IO) and intravenous (IV) whole blood transfusion relative to hemolysis and transfusion time. Swine were assigned to the IV group (n = 6) with an 18-gauge catheter in the auricular vein or the IO group (n = 7) with a 15-gauge 10 needle in the proximal humerus. Following baseline specimen collection, 900 mL of blood was collected from each animal.

It is a common belief that changing answers on multiple-choice examinations is detrimental, and such action usually results in changing from right to wrong. Over the past 60 years, studies have shown that changing answers on multiple-choice examinations is generally beneficial. The misconception regarding answer changing behavior may be perpetuated by faculty despite evidence to the contrary.

Background: Military healthcare personnel, including nurse anesthetists, must have the knowledge and skills to care for the extensive, severe injuries incurred on the battlefield. No studies have compared the 2 teaching strategies of using the human patient simulator (HPS) and a CD-ROM in caring for combat injuries relative to critical thinking and performance using nurse anesthesia participants.

Methods: A prospective, pretest-posttest experimental, mixed design (within and between) was used to determine if there were statistically significant differences in HPS and CD-ROM educational strategies relative to caring for patients who have trauma.

Objectives: Military health care personnel need to have skills relative to caring for patients on the battlefield. No studies have compared the two teaching strategies of using the human patient simulator (HPS) and a CD-ROM in caring for combat injuries. The objective of this study was to determine if there were statistically significant differences in HPS and CD-ROM educational strategies relative to caring for patients who have trauma.

Objectives: To evaluate a eight-session cognitive behavior therapy (CBT) intervention tailored to adaptation in implantable cardioverter defibrillator (ICD) patients; and to test for treatment group by gender interaction effects.

Methods: Patients receiving their first ICD implant were randomized to CBT or usual cardiac care. Primary outcomes measured at baseline, 6-month, and 12-month follow-ups were symptoms of anxiety and depression (Hospital Anxiety and Depression Scale), posttraumatic stress disorder symptoms (Impact of Events Scale-Revised), and phobic anxiety (Crown-Crisp Experiential Index).
