What Can We Learn from Parents of Caries-Free and Caries-Active Hispanic Children?
ObjectiveThis study evaluated strength-based motivators within Hispanic families that support the creation of health in their children. A mixed-methods approach was used to understand differences in Hispanic parental factors between caries-free (CF) and caries-active (CA) children.MethodsA cross-sectional survey was conducted with 200 parent-child triads (primary child: between 0 and 6 y; reference child: between 0 and 10 y) recruited from health centers in the Denver Metro area. All the participating children received an oral examination, and the triads were grouped as CF or CA based on the caries status of the primary child. Qualitative data were collected through in-depth individual interviews with the parents. The analysis only involved the primary child. Bivariable analysis were conducted between parent factors (independent variables) and presence or absence of caries (outcome variable). The variables with P < 0.20 in the bivariable analysis were subjected to 2 multivariable logistic regression models. The children in the CF group had mean (SD) age of 2.8 (1.28) y compared to the CA group at 4.0 (1.55) y (P < 0.001). Bivariable analysis demonstrated that parents in the CF group reported higher oral hygiene behavior scores (P = 0.047), perceived fewer barriers (P = 0.009) to accessing preventive dental care, and considered their children more susceptible to cavities (P = 0.001) compared to parents in the CA group. Multivariable model (adjusting for socioeconomic characteristics) demonstrated that parents of CF children perceived high susceptibility to caries for their children (P = 0.040). Multivariable model (adjusting for acculturation) demonstrated an association of parental oral hygiene behavior (P = 0.040) and parent-perceived susceptibility to caries (P = 0.010) with CF child status. Qualitative interviews revealed that parents in the CF group were concerned about their children's higher susceptibility to caries and tried to establish good oral hygiene routines for their children.ConclusionThe results of this study demonstrated that parental behaviors and health beliefs could be significant determinants of caries status in Hispanic children.Knowledge transfer statementResults of this study indicate that parental oral health beliefs and behaviors are significant determinants of caries status in children of Hispanic population. Parental beliefs could motivate them to take action or establish behavior that prevents dental caries in their children. Health care providers and caries prevention efforts can incorporate this information to tailor oral health promotional messaging and approaches to improve the oral health of Hispanic children

Open data from the first and second observing runs of Advanced LIGO and Advanced Virgo
Advanced LIGO and Advanced Virgo are monitoring the sky and collecting gravitational-wave strain data with sufficient sensitivity to detect signals routinely. In this paper we describe the data recorded by these instruments during their first and second observing runs. The main data products are gravitational-wave strain time series sampled at 16384 Hz. The datasets that include this strain measurement can be freely accessed through the Gravitational Wave Open Science Center at http://gw-openscience.org, together with data-quality information essential for the analysis of LIGO and Virgo data, documentation, tutorials, and supporting software
Search for intermediate-mass black hole binaries in the third observing run of Advanced LIGO and Advanced Virgo
International audienceIntermediate-mass black holes (IMBHs) span the approximate mass range 100â105âMâ, between black holes (BHs) that formed by stellar collapse and the supermassive BHs at the centers of galaxies. Mergers of IMBH binaries are the most energetic gravitational-wave sources accessible by the terrestrial detector network. Searches of the first two observing runs of Advanced LIGO and Advanced Virgo did not yield any significant IMBH binary signals. In the third observing run (O3), the increased network sensitivity enabled the detection of GW190521, a signal consistent with a binary merger of mass âŒ150âMâ providing direct evidence of IMBH formation. Here, we report on a dedicated search of O3 data for further IMBH binary mergers, combining both modeled (matched filter) and model-independent search methods. We find some marginal candidates, but none are sufficiently significant to indicate detection of further IMBH mergers. We quantify the sensitivity of the individual search methods and of the combined search using a suite of IMBH binary signals obtained via numerical relativity, including the effects of spins misaligned with the binary orbital axis, and present the resulting upper limits on astrophysical merger rates. Our most stringent limit is for equal mass and aligned spin BH binary of total mass 200âMâ and effective aligned spin 0.8 at 0.056 Gpcâ3 yrâ1 (90% confidence), a factor of 3.5 more constraining than previous LIGO-Virgo limits. We also update the estimated rate of mergers similar to GW190521 to 0.08 Gpcâ3 yrâ1.Key words: gravitational waves / stars: black holes / black hole physicsCorresponding author: W.
