Applying systems thinking to identify enablers and challenges to scale-up interventions for hypertension and diabetes in low-income and middle-income countries: protocol for a longitudinal mixed-methods study.

Introduction: There is an urgent need to reduce the burden of non-communicable diseases (NCDs), particularly in low-and middle-income countries, where the greatest burden lies. Yet, there is little research concerning the specific issues involved in scaling up NCD interventions targeting low-resource settings. We propose to examine this gap in up to 27 collaborative projects, which were funded by the Global Alliance for Chronic Diseases (GACD) 2019 Scale Up Call, reflecting a total funding investment of approximately US$50 million.

Facilitating Advanced Research Skills Beyond the Undergraduate Dental Hygiene Curricula.

Dental hygiene educators play a key role in assisting students to make connections between research and clinical practice. A core course in research was redesigned with the goal of motivating and encouraging dental hygiene students to advance research skills beyond the undergraduate dental hygiene curricula. The purpose of this pilot study was to evaluate the redesigned course and the student outcomes as they relate to perceived barriers and motivation for future research in dental hygiene.

Silver diamine fluoride, atraumatic restorations, and oral health-related quality of life in children aged 5-13 years: results from the CariedAway school-based cluster randomized trial.

Objective: Silver diamine fluoride (SDF) is a non-surgical treatment for the arrest and prevention of dental caries that results in irreversible black staining of dental decay. The objective of this study was to evaluate the short-term impact of SDF treatment on oral health-related quality of life (OHRQoL) relative to a standard package of glass ionomer sealants and atraumatic restorative treatment (ART) in children aged 5-13 years.

Methods: CariedAway is a pragmatic, longitudinal, cluster-randomized non-inferiority trial of non-surgical interventions for caries.

The small molecule compound C65780 alleviates pain by stabilizing voltage-gated sodium channels in the inactivated and slowly-recovering state.

Noxious pain signals are transduced in the peripheral nervous system as action potentials, which rely on the activities of voltage-gated sodium channels (NaVs). Blocking NaVs is thus a valuable strategy for pain treatment. Here, we report the characterization of a novel NaVs antagonist, 2-(2-(diethylamino)ethyl)indeno[1,2,3-de]phthalazin-3(2H)-one (C65780), and investigation of its action mechanisms.

COVID-19-Associated cardiac pathology at the postmortem evaluation: a collaborative systematic review.

Background: Many postmortem studies address the cardiovascular effects of COVID-19 and provide valuable information, but are limited by their small sample size.

Objectives: The aim of this systematic review is to better understand the various aspects of the cardiovascular complications of COVID-19 by pooling data from a large number of autopsy studies.

Data Sources: We searched the online databases Ovid EBM Reviews, Ovid Embase, Ovid Medline, Scopus, and Web of Science for concepts of autopsy or histopathology combined with COVID-19, published between database inception and February 2021.

Confronting Racism in All Forms of Pain Research: A Shared Commitment for Engagement, Diversity, and Dissemination.

This third paper in the "Confronting Racism in All Forms of Pain Research" series discusses adopting an antiracism framework across all pain research disciplines and highlights the significant benefits of doing so. We build upon the previous call to action and the proposed reframing of study designs articulated in the other papers in the series and seek to confront and eradicate racism through a shared commitment to change current research practices. Specifically, we emphasize the systematic disadvantage created by racialization (ie, the Eurocentric social and political process of ascribing racialized identities to a relationship, social practice, or group) and discuss how engaging communities in partnership can increase the participation of racialized groups in research studies and enrich the knowledge gained.

The dilemma of different dental degrees: DDS and DMD.

Although the Doctor of Dental Surgery (DDS) evolved from the surgical and the Doctor of Medicine in Dentistry (DMD) from the medical (DMD) roots of the dental profession, dental schools in the US currently award both degrees, verified as equivalent by finding no differences between them in standards of admissions, accreditation, or state licensure requirements while continuing to be subjectively perceived as different enough to create professional and public confusion. In contrast, Doctors of Osteopathy (DOs) and Doctors of Medicine (MDs) are both objectively and subjectively perceived as different in philosophy and healthcare training while objectively passing similar examinations to be licensed as physicians. Following from the history of both dental degrees and their implications for training and dental practice, the objective of this manuscript is to update the scientific, socio-political, and professional reasons for awarding only the DMD for future graduates while continuing to recognize the contributions of DDS graduates to oral healthcare.

Oral cancer induced TRPV1 sensitization is mediated by PAR signaling in primary afferent neurons innervating the cancer microenvironment.

Oral cancer patients report sensitivity to spicy foods and liquids. The mechanism responsible for chemosensitivity induced by oral cancer is not known. We simulate oral cancer-induced chemosensitivity in a xenograft oral cancer mouse model using two-bottle choice drinking and conditioned place aversion assays.

Effects of a local single dose administration of growth hormone on the osseointegration of titanium implants.

Background: The aim of the present study was to evaluate the effect of different concentrations of growth hormone (GH) on endosteal implant's surface at the early stages of osseointegration.

Material And Methods: Sixty tapered acid-etched titanium implants were divided into four groups: i) Collagen, used as a control group; and three experimental groups, where after collagen coating, GH was administered directly to the surface in varying concentrations: ii) 0.265 mg, iii) 0.

The influence of professional oral hygiene care on reducing ventilator-associated pneumonia in trauma intensive care unit patients.

Aim This study aimed to examine the effects of professional oral hygiene care for the prevention of ventilator-associated pneumonia (VAP) and the improvement of oral hygiene among patients in the trauma intensive care unit (TICU).Materials and methods TICU patients who underwent intubation were randomly assigned to either the experimental group (n = 29) or control group (n = 28). The developed professional oral hygiene care protocol was administered to patients in the experimental group every 24 hours.

3D-printed resins for provisional dental restorations: Comparison of mechanical and biological properties.

Objectives: To characterize the mechanical and biological properties of three commercially available resins, which are currently used for provisional restorations and to compare them to an experimental resin intended for definitive fixed dental prostheses.

Materials And Methods: Three commercially available resins: Crowntec (CT, Saremco), Temporary C&B (FL, Formlabs), C&B MFH (ND, Nextdent), and the experimental resin: Permanent Bridge (PB, Saremco) were printed and subjected to biaxial flexural strength test, finite element analysis, Weibull analysis, scanning electron microscopy, cell proliferation, immunohistochemistry and cytotoxicity assays. Samples from CT, PB, and ND were provided directly from the manufacturers ensuring ideal workflow.

Junior faculty perspectives on the academic environment: A call for development and onboarding.

Background: One challenge in dental education is new faculty members can be hired with limited teaching experience or understanding of pedagogy. Recent publications document increasing initiatives of faculty development in US and Canadian dental schools. This study evaluates full-time faculty perspectives of their develop and academic environment.

Intrahepatic microbes govern liver immunity by programming NKT cells.

The gut microbiome shapes local and systemic immunity. The liver is presumed to be a protected sterile site. As such, a hepatic microbiome has not been examined.

The mycobiome-immune axis: The next frontier in pancreatic cancer.

In this issue of Cancer Cell, Aftab et al. identify a pro-inflammatory cytokine, IL-33, that is released as a chemoattractant for type 2 immune cells in response to the intratumoral mycobiome. Depletion of fungi or deletion of IL-33 in cancer cells significantly decreases pancreatic ductal adenocarcinoma (PDAC) tumor progression and increases survival.

Schwann cell endosome CGRP signals elicit periorbital mechanical allodynia in mice.

Efficacy of monoclonal antibodies against calcitonin gene-related peptide (CGRP) or its receptor (calcitonin receptor-like receptor/receptor activity modifying protein-1, CLR/RAMP1) implicates peripherally-released CGRP in migraine pain. However, the site and mechanism of CGRP-evoked peripheral pain remain unclear. By cell-selective RAMP1 gene deletion, we reveal that CGRP released from mouse cutaneous trigeminal fibers targets CLR/RAMP1 on surrounding Schwann cells to evoke periorbital mechanical allodynia.

Mice expressing fluorescent PAR reveal that endocytosis mediates colonic inflammation and pain.

G protein-coupled receptors (GPCRs) regulate many pathophysiological processes and are major therapeutic targets. The impact of disease on the subcellular distribution and function of GPCRs is poorly understood. We investigated trafficking and signaling of protease-activated receptor 2 (PAR) in colitis.

Associations between Spiritual Health Locus of Control, Perceived Discrimination and Breast and Cervical Cancer Screening for Muslim American Women in New York City.

Background: We sought to understand the impacts of religion-related factors, namely perceived discrimination and spiritual health locus of control, on breast and cervical cancer screening for Muslim American women.

Methods: A total of 421 Muslim American women were surveyed at baseline of a breast and cervical cancer screening intervention, measuring discrimination through the Perceived Ethnic Discrimination Questionnaire (PED-Q), a 17-item scale measuring perceived interpersonal racial/ethnic discrimination; and spiritual beliefs through the Spiritual Health Locus of Control Scale, a 13-item scale measuring the link between control over one's health with a connection to religious beliefs. Multivariable logistic regression models were used to determine factors associated with an up-to-date mammogram and Pap test.

The Brain-Nose Interface: A Potential Cerebrospinal Fluid Clearance Site in Humans.

The human brain functions at the center of a network of systems aimed at providing a structural and immunological layer of protection. The cerebrospinal fluid (CSF) maintains a physiological homeostasis that is of paramount importance to proper neurological activity. CSF is largely produced in the choroid plexus where it is continuous with the brain extracellular fluid and circulates through the ventricles.

Injectable recombinant block polymer gel for sustained delivery of therapeutic protein in post traumatic osteoarthritis.

Protein-based biomaterials offer several advantages over synthetic materials, owing to their unique stimuli-responsive properties, biocompatibility and modular nature. Here, we demonstrate that EC, a recombinant protein block polymer, consisting of five repeats of elastin like polypeptide (E) and a coiled-coil domain of cartilage oligomeric matrix protein (C), is capable of forming a porous networked gel at physiological temperature, making it an excellent candidate for injectable biomaterials. Combination of EC with Atsttrin, a chondroprotective engineered derivative of anti-inflammatory growth factor progranulin, provides a unique biochemical and biomechanical environment to protect against post-traumatic osteoarthritis (PTOA) onset and progression.

Mibefradil alters intracellular calcium concentration by activation of phospholipase C and IP receptor function.

Mibefradil is a tetralol derivative originally developed as an antagonist of T-type voltage-gated calcium (Ca) channels to treat hypertension when used at nanomolar dosage. More recently, its therapeutic application in hypertension has declined and has been instead repurposed as a treatment of cancer cell proliferation and solid tumor growth. Beyond its function as a Ca blocker, the micromolar concentration of mibefradil can stimulate a rise in [Ca] although the mechanism is poorly known.
