A Patient-Centered Perspective on Changes in Personal Characteristics After Deep Brain Stimulation.

Importance: Deep brain stimulation (DBS) results in improvements in motor function and quality of life in patients with Parkinson disease (PD), which might impact a patient's perception of valued personal characteristics. Prior studies investigating whether DBS causes unwanted changes to oneself or one's personality have methodological limitations that should be addressed.

Objective: To determine whether DBS is associated with changes in characteristics that patients with PD identify as personally meaningful.

Building expert consensus regarding sharing of individual research results in Alzheimer's disease research: a Delphi study protocol.

Introduction: Informed decisions to enrol in the clinical investigations of Alzheimer's disease and related dementias (ADRD) require careful consideration of complex risks and uncertain benefits. Decisions regarding whether to receive information about biomarker status are complicated by lack of scientific consensus regarding biomarkers as surrogate endpoints for Alzheimer's disease and how information about individual risk should be evaluated and shared with research participants. This study aims to establish stakeholder consensus regarding ethically optimal approaches to sharing individual results with ADRD research participants.

Perspectives on the role of the nurse ethicist.

This paper offers four contrasting perspectives on the role of the nurse ethicist from authors based in different areas of world, with different professional backgrounds and at different career stages. Each author raises questions about how to understand the role of the nurse ethicist. The first author reflects upon their career, the scope and purpose of their work, ultimately arguing that the distinction between 'nurse ethicist' and 'clinical ethicist' is largely irrelevant.

Overcoming barriers to informed consent in neurological research: Perspectives from a national survey.

The ethical recruitment of participants with neurological disorders in clinical research requires obtaining initial and ongoing informed consent. The purpose of this study is to characterize barriers faced by research personnel in obtaining informed consent from research participants with neurological disorders and to identify strategies applied by researchers to overcome those barriers. This study was designed as a web-based survey of US researchers with an optional follow-up interview.

Antimicrobial stewardship: Prescribing across the primary care health professions.

We examined the patterns of antibiotic prescribing by medical and non-medical prescribers (dentists, nurse practitioners, and midwives) in Australia. We explored trends in the dispensed use of antibiotics (scripts and defined daily dose [DDD] per 1000 population/day) by Australian prescribers over the 12-year period, 2005-2016. We obtained data on dispensed prescriptions of antibiotics from registered health professionals subsidized on the Pharmaceutical Benefits Scheme (PBS).

Virtual prenatal visits associated with high measures of patient experience and satisfaction among average-risk patients: a prospective cohort study.

Background: Virtual visits have the potential to decrease barriers to prenatal care stemming from transportation, work, and childcare concerns. However, data regarding patient experience and satisfaction with virtual visits remain limited in obstetrics. To address this gap, we explore average-risk pregnant women's experiences with virtual visits and compare satisfaction with virtual vs.

Dynamic dentin: A quantitative microscopic assessment of age and spatial changes to matrix architecture, peritubular dentin, and collagens types I and III.

To investigate age and site-related changes to human dentin collagen, sound human teeth collected from donors aged 13-29 (young) and 50-74 (aged) years (n = 9/group) were cut to shallow and deep sites. Dentin collagen orientation and fibril bundling was investigated using the Picrosirius Red (PSR) stain observed under cross-polarized light microscopy (Pol), and collagen distribution was investigated using Confocal Laser Scanning Microscopy (CLSM). Collagen types III to I distribution in peritubular dentin (PTD) was revealed using Herovici stain and brightfield microscopy.

Coronal dentin differs between young and mature adult humans: A systematic review.

Objective: This systematic review examines the effect of age on changes to coronal dentin properties.

Design: Pubmed, Cinhal, Scopus, Web of Science and the Cochrane Database were searched for publications up to 31 December 2021. All studies were uploaded and reviewed using Covidence software.

Effect of dentine site on resin and cement adaptation tested using X-ray and electron microscopy to evaluate bond durability and adhesive interfaces.

Glass ionomer (GI) cements and self-etch (SE) or universal adhesives after etching (ER) adapt variably with dentine. Dentine characteristics vary with depth (deep/shallow), location (central/peripheral), and microscopic site (intertubular/peritubular). To directly compare adhesion to dentine, non-destructive imaging and testing are required.

Does dentine mineral change with anatomical location, microscopic site and patient age?

Objective: To determine the effect of patient age (young or mature), anatomical location (shallow/deep and central/peripheral) and microscopic site (intertubular/peritubular) on dentine mineral density, distribution and composition.

Methods: Extracted posterior teeth from young (aged 19-20 years, N = 4) and mature (aged 54-77 years, N = 4) subjects were prepared to shallow and deep slices. The dentine surface elemental composition was investigated in a SEM using Backscattered Electron (BSE) micrographs, Energy Dispersive X-ray Spectroscopy, and Integrated Mineral Analysis.

Improving Real-World Innovation and Problem Solving in Clinical Ethics: Insights from the First Clinical Ethics Un-Conference.

Despite an abundance of academic conferences, clinical ethicists lacked a forum to share innovative practices with peers and to generate solutions to common challenges. Organizers of the first Clinical Ethics Un-Conference developed a working event centered on active participation and problem solving through peer learning, with the goal of improving real-world practice. Registrants included 95 individuals from 64 institutions.

Exit from Brain Device Research: A Modified Grounded Theory Study of Researcher Obligations and Participant Experiences.

As clinical trials end, little is understood about how participants exiting from clinical trials approach decisions related to the removal or post-trial use of investigational brain implants, such as deep brain stimulation (DBS) devices. This empirical bioethics study examines how research participants experience the process of exit from research at the end of clinical trials of implanted neural devices. Using a modified grounded theory study design, we conducted semi-structured, in-depth interviews with 16 former research participants from clinical trials of DBS and responsive neurostimulation (RNS).

Discovery of Potent, Selective Triazolothiadiazole-Containing c-Met Inhibitors.

Herein, we report a novel series of highly potent and selective triazolothiadiazole c-Met inhibitors. Starting with molecule , we have applied structure-based drug design principles to identify the triazolothiadiazole ring system. We successfully replaced the metabolically unstable phenolic moiety with a quinoline group.

Empathetic, persistent and female: A snapshot of oral health therapy students in Australia and New Zealand.

Introduction: Dental therapists, hygienists and oral health therapists constitute up to a third of the dental workforce in Australia and New Zealand. Personality is often explored in health professions to provide insights into traits that are conducive to workforce retention and to assist in planning and training. This study aimed to investigate the current demographic and personality characteristics of oral health students in Australia and New Zealand.

Trends in Australian dental prescribing of antibiotics: 2005-2016.

Background: Prescribing of antibiotics by dentists for surgical prophylaxis or as an adjunct to managing dental infections is a substantial part of the overall landscape for prescribed antibiotics in health care settings.

Methods: We explored trends in the antibiotic prescribing patterns of Australian dentists over the 12-year period, 2005-2016. We obtained data on dispensed prescriptions of antibiotics from registered dentists subsidized on the Pharmaceutical Benefits Scheme.

Tobacco Use and Oral Health.

This review outlines the important oral implications of tobacco use. The lining of the mouth (oral mucosa), if exposed to tobacco and its products in a susceptible individual, can develop benign, potentially malignant, and malignant tumours. Treatment and prognosis depend on tumour type, how early it is detected, its size and site in the oral cavity and whether it has spread.
