An Analysis of Patient Perceptions and Expectations to Dental Implants: Is There a Significant Effect on Long-Term Satisfaction Levels?

Shane J. J. McCrea · 2017 · International Journal of Dentistry

Here we present an analysis of patient perceptions and expectations to dental implant placement and their prosthetic reconstruction, to then consider whether they have an effect on long-term satisfaction levels. A Post-Treatment Completion Questionnaire was designed to analyse whether patient satisfaction is influenced by age and/or gender; has an effect on patient-reported self-confidence levels; contributes to increased levels of oral hygiene; provides further insight into the average pain levels during and after the surgical intervention; or influences further acceptance of dental implant s

KC-SMARTR: An R package for detection of statistically significant aberrations in multi-experiment aCGH data

Jorma J. de Ronde, Christiaan Klijn, Arno Velds et al. · 2010 · BMC Research Notes

BACKGROUND: Most approaches used to find recurrent or differential DNA Copy Number Alterations (CNA) in array Comparative Genomic Hybridization (aCGH) data from groups of tumour samples depend on the discretization of the aCGH data to gain, loss or no-change states. This causes loss of valuable biological information in tumour samples, which are frequently heterogeneous. We have previously developed an algorithm, KC-SMART, that bases its estimate of the magnitude of the CNA at a given genomic location on kernel convolution (Klijn et al., 2008). This accounts for the intensity of the probe sign

DNA Methylation Signatures of Breastfeeding in Buccal Cells Collected in Mid-Childhood

Veronika V. Odintsova, Fiona A. Hagenbeek, Matthew Suderman et al. · 2019 · Nutrients

Breastfeeding has long-term benefits for children that may be mediated via the epigenome. This pathway has been hypothesized, but the number of empirical studies in humans is small and mostly done by using peripheral blood as the DNA source. We performed an epigenome-wide association study (EWAS) in buccal cells collected around age nine (mean = 9.5) from 1006 twins recruited by the Netherlands Twin Register (NTR). An age-stratified analysis examined if effects attenuate with age (median split at 10 years; n<10 = 517, mean age = 7.9; n>10 = 489, mean age = 11.2). We performed replication

Null results of oxytocin and vasopressin administration on mentalizing in a large fMRI sample: evidence from a randomized controlled trial

Mark A. Straccia, Adam R. Teed, Perri L. Katzman et al. · 2021 · Psychological Medicine

BACKGROUND: Although potential links between oxytocin (OT), vasopressin (AVP), and social cognition are well-grounded theoretically, most studies have included all male samples, and few have demonstrated consistent effects of either neuropeptide on mentalizing (i.e. understanding the mental states of others). To understand the potential of either neuropeptide as a pharmacological treatment for individuals with impairments in social cognition, it is important to demonstrate the beneficial effects of OT and AVP on mentalizing in healthy individuals. METHODS: = 186) of healthy individuals, we exa

The reliability characteristics of the REFLECT rubric for assessing reflective capacity through expressive writing assignments: A replication study

Lawrence Grierson, Samantha Winemaker, Alan Taniguchi et al. · 2020 · Perspectives on Medical Education

INTRODUCTION: The medical education community has implemented writing exercises that foster critical analysis and nurture reflective capacity. The REFLECT rubric (Wald et al. 2012) was developed to address the challenge of assessing these written reflections. The objective of this replication work is to explore the reproducibility of the reliability characteristics presented by the REFLECT developers. METHODS: Five raters evaluated narratives written by medical students and experienced clinicians using the REFLECT rubric. Reliability across rubric domains was determined via intraclass correlat

Cry1Ac Transgenic Sugarcane Does Not Affect the Diversity of Microbial Communities and Has No Significant Effect on Enzyme Activities in Rhizosphere Soil within One Crop Season

Dinggang Zhou, Liping Xu, Shiwu Gao et al. · 2016 · Frontiers in Plant Science

Cry1Ac transgenic sugarcane provides a promising way to control stem-borer pests. Biosafety assessment of soil ecosystem for cry1Ac transgenic sugarcane is urgently needed because of the important role of soil microorganisms in nutrient transformations and element cycling, however little is known. This study aimed to explore the potential impact of cry1Ac transgenic sugarcane on rhizosphere soil enzyme activities and microbial community diversity, and also to investigate whether the gene flow occurs through horizontal gene transfer. We found no horizontal gene flow from cry1Ac sugarcane to soi

Development and characterisation of 3D collagen-gelatin based scaffolds for breast cancer research

John Redmond, Helen O. McCarthy, Paul Buchanan et al. · 2022 · Biomaterials Advances

While 2D culture presents a useful tool for cancer research, it fails to replicate the tumor microenvironment as it lacks proper three-dimensional cell-cell/cell-matrix interactions, often resulting in exaggerated responses to therapeutic agents. 3D models that aim to overcome the issues associated with 2D culture research offer a new frontier for cancer research with cell growth, morphology and genetic properties that more closely match in vivo cancers. Herein, we aim to develop a collagen-based scaffold that supports the attachment and proliferation of breast cancer (BC) cells as a 3D cultur

Contest-Based and Norm-Based Interventions: (How) Do They Differ in Attitudes, Norms, and Behaviors?

Magnus Bergquist, Andréas Nilsson, Emma Ejelöv · 2019 · Sustainability

Setting up a contest is a popular means to promote pro-environmental behaviors. Yet, research on contest-based interventions is scarce while norm-based interventions have gained much attention. In two field experiments, we randomly assigned 79 apartments to either a contest-based or a norm-based electricity conservation intervention and measured kWh usage for 2 and 4 weeks, respectively. Results from both studies showed that contest-based interventions promote intensive but short-lived electricity saving. In Study 1 apartments assigned to a norm-based intervention showed more stable electricit

Genetic susceptibility loci of idiopathic interstitial pneumonia do not represent risk for systemic sclerosis: a case control study in Caucasian patients

Minghua Wu, Shervin Assassi, Gloria A. Salazar et al. · 2016 · Arthritis Research & Therapy

BACKGROUND: Systemic sclerosis (SSc)-related interstitial lung disease (ILD) has phenotypic similarities to lung involvement in idiopathic interstitial pneumonia (IIP). We aimed to assess whether genetic susceptibility loci recently identified in the large IIP genome-wide association studies (GWASs) were also risk loci for SSc overall or severity of ILD in SSc. METHODS: A total of 2571 SSc patients and 4500 healthy controls were investigated from the US discovery GWAS and additional US replication cohorts. Thirteen IIP-related selected single nucleotide polymorphisms (SNPs) were genotyped and

Joint polygenic and environmental risks for childhood attention‐deficit/hyperactivity disorder (ADHD) and ADHD symptom dimensions

Michael A. Mooney, Peter Ryabinin, Hannah E. Morton et al. · 2023 · JCPP Advances

Abstract Background attention‐deficit/hyperactivity disorder (ADHD) is associated with both polygenic liability and environmental exposures, both intrinsic to the family, such as family conflict, and extrinsic, such as air pollution. However, much less is known about the interplay between environmental and genetic risks relevant to ADHD—a better understanding of which could inform both mechanistic models and clinical prediction algorithms. Methods Two independent data sets, the population‐based Adolescent Brain Cognitive Development Study (ABCD) ( N = 11,876) and the case‐control Oregon‐ADHD‐1

Association Between Care Utilization and Anxiety Outcomes in an On-Demand Mental Health System: Retrospective Observational Study

Sarah Kunkle, Manny Yip, Justin Hunt et al. · 2020 · JMIR Formative Research

BACKGROUND: Anxiety is an extremely prevalent condition, and yet, it has received notably less attention than depression and other mental health conditions from a research, clinical, and public health perspective. The COVID-19 pandemic has only exacerbated growing concerns about the burden of anxiety due to the confluence of physical health risks, economic stressors, social isolation, and general disruption of daily activities. OBJECTIVE: This study examines differences in anxiety outcomes by care modality (coaching, teletherapy and telepsychiatry, and combined care) within an on-demand mental
