Esthetic Outcomes of Implant-Supported Single Crowns Related to Abutment Type and Material: A Systematic Review.

Int J Prosthodont 2021 Mar-Apr;34(2):229-249

Purpose: To systematically review the influence of abutment material and configuration on the soft tissue esthetic outcomes of implant-supported single crowns (iSCs) after 3 years.

Materials And Methods: An electronic search on MEDLINE (PubMed) from January 2000 to July 2019 was conducted for clinical trials with no language restrictions. The focus question was: In partially edentulous patients with iSCs, does the abutment material (metal vs ceramic) or the configuration (standardized vs customized) have an effect on the soft tissue esthetic outcomes? Randomized controlled trials, controlled clinical trials, and prospective or retrospective case series with at least 10 patients and a minimum of 3 years of follow-up were included. Read More

Perceptual Inference, Learning, and Attention in a Multisensory World.

Authors:
Uta Noppeney

Annu Rev Neurosci 2021 Apr 21. Epub 2021 Apr 21.

Donders Institute for Brain, Cognition and Behavior, Radboud University, 6525 AJ Nijmegen, The Netherlands; email:

Adaptive behavior in a complex, dynamic, and multisensory world poses some of the most fundamental computational challenges for the brain, notably inference, decision-making, learning, binding, and attention. We first discuss how the brain integrates sensory signals from the same source to support perceptual inference and decision-making by weighting them according to their momentary sensory uncertainties. We then show how observers solve the binding or causal inference problem-deciding whether signals come from common causes and should hence be integrated or else be treated independently. Read More

JMIR Res Protoc 2021 Mar 9. Epub 2021 Mar 9.

Department of Prevention and Community Health, Milken Institute School of Public Health, The George Washington University, Washington DC, USA, Washington, US.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a coronavirus novel discovered in December 2019 and is currently the cause of a global pandemic. A critical aspect of fighting this pandemic is by obtaining accurate and timeous test results so that positive identified cases can be isolated to reduce the spread. Research has shown that saliva is a promising candidate for SARS-CoV-2 diagnostics because collection is minimally invasive and can reliably be self-administered. Read More

#StrongerTogether - Utilizing Health Behavior Change and Technology Acceptance Models to Predict Adoption of COVID-19 Contact Tracing Apps: A Cross-Sectional Survey.

J Med Internet Res 2021 Apr 11. Epub 2021 Apr 11.

Department Health and Prevention, Institute of Psychology, University of Greifswald, Robert-Blum-Straße 13, Greifswald, DE.

Background: To combat the global COVID-19 pandemic, contact tracing apps have been discussed as digital health solutions to track infection chains, and provide appropriate information. However, observational studies point to a low acceptance in most countries, and few studies have yet examined theory-based predictors of app use in the general population to guide health communication efforts.

Objective: Therefore, this study utilizes established health behavior change and technology acceptance models to predict adoption intentions and frequency of current app use. Read More

Mining and Validating Social Media for COVID-19-Related Human Behaviors between January and July 2020; An Infodemiology Study.

J Med Internet Res 2021 Apr 17. Epub 2021 Apr 17.

Analytics, Intelligence, and Technology, Los Alamos National Laboratory, Los Alamos National Laboratory, Los Alamos, US.

Background: Health authorities can minimize the impact of an emergent infectious disease outbreak through effective and timely risk communication, which can build trust and adherence to subsequent behavioral messaging. Monitoring the psychological impacts of an outbreak, as well as public adherence to such messaging is also important for minimizing long-term effects of an outbreak.

Surgical volume reduction and the announcement of triage during the 1st wave of the COVID-19 pandemic in Japan: a cohort study using an interrupted time series analysis.

Surg Today 2021 Apr 21. Epub 2021 Apr 21.

Department of Healthcare Economics and Quality Management, Graduate School of Medicine, Kyoto University, Kyoto City, Kyoto, Japan.

JAMA Netw Open 2021 Apr 1;4(4):e215845. Epub 2021 Apr 1.

Department of Neurology, Mount Sinai Beth Israel, and Icahn School of Medicine, Mount Sinai, New York, New York.

Importance: Despite a hypothesis that harboring a leucine-rich repeat kinase 2(LRRK2) G2019S variation and a glucocerebrosidase (GBA) variant would have a combined deleterious association with disease pathogenesis, milder clinical phenotypes have been reported in dual LRRK2 and GBA variations Parkinson disease (PD) than in GBA variation PD alone.

Objective: To evaluate the association of LRRK2 G2019S and GBA variants with longitudinal cognitive and motor decline in PD.

Design, Setting, And Participants: This longitudinal cohort study of continuous measures in LRRK2 PD, GBA PD, LRRK2/GBA PD, and wild-type idiopathic PD used pooled annual visit data ranging from 2004 to 2019 from the Mount Sinai Beth Israel, Parkinson Disease Biomarker Program, Harvard Biomarkers Study, Ashkenazi Jewish-LRRK2-Consortium, Parkinson Progression Marker Initiative, and SPOT-PD studies.

Association of Multigenerational Family History of Depression With Lifetime Depressive and Other Psychiatric Disorders in Children: Results from the Adolescent Brain Cognitive Development (ABCD) Study.

JAMA Psychiatry 2021 Apr 21. Epub 2021 Apr 21.

Department of Psychiatry, Vagelos College of Physicians and Surgeons, Columbia University Irving Medical Center, New York, New York.

Importance: Three-generation family studies of depression have established added risk of psychopathology for offspring with 2 previous generations affected with depression compared with 1 or none. Because of their rigorous methodology, there are few of these studies, and existing studies are limited by sample sizes. Consequently, the 3-generation family risk paradigm established in family studies can be a critical neuropsychiatric tool if similar transmission patterns are reliably demonstrated with the family history method.

Nutritional Implications of Baby-Led Weaning and Baby Food Pouches as Novel Methods of Infant Feeding: Protocol for an Observational Study.

JMIR Res Protoc 2021 Apr 21;10(4):e29048. Epub 2021 Apr 21.

Department of Human Nutrition, University of Otago, Dunedin, New Zealand.

Background: The complementary feeding period is a time of unparalleled dietary change for every human, during which the diet changes from one that is 100% milk to one that resembles the usual diet of the wider family in less than a year. Despite this major dietary shift, we know relatively little about food and nutrient intake in infants worldwide and virtually nothing about the impact of baby food "pouches" and "baby-led weaning" (BLW), which are infant feeding approaches that are becoming increasingly popular. Pouches are squeezable containers with a plastic spout that have great appeal for parents, as evidenced by their extraordinary market share worldwide. Read More
