We search for the baryon acoustic oscillations in the projected cross-correlation function binned into transverse comoving radius between the SDSS-IV DR16 eBOSS quasars and a dense photometric sample of galaxies selected from the DESI Legacy Imaging Surveys. We estimate the density of the photometric sample of galaxies in this redshift range to be about 2900 deg−2, which is deeper than the official DESI emission line galaxy selection, and the density of the spectroscopic sample is about 20 deg−2. In order to mitigate the systematics related to the use of different imaging surveys close to the detection limit, we use a neural network approach that accounts for complex dependences between the imaging attributes and the observed galaxy density. We find that we are limited by the depth of the imaging surveys that affects the density and purity of the photometric sample and its overlap in redshift with the quasar sample, which thus affects the performance of the method. When cross-correlating the photometric galaxies with quasars in the range 0.6 ≤ z ≤ 1.2, the cross-correlation function can provide better constraints on the comoving angular distance DM (6 per cent precision) compared to the constraint on the spherically averaged distance DV (9 per cent precision) obtained from the autocorrelation. Although not yet competitive, this technique will benefit from the arrival of deeper photometric data from upcoming surveys that will enable it to go beyond the current limitations we have identified in this work.

We present the cosmological implications from final measurements of clustering using galaxies, quasars, and Lyα forests from the completed Sloan Digital Sky Survey (SDSS) lineage of experiments in large-scale structure. These experiments, composed of data from SDSS, SDSS-II, BOSS, and eBOSS, offer independent measurements of baryon acoustic oscillation (BAO) measurements of angular-diameter distances and Hubble distances relative to the sound horizon, rd, from eight different samples and six measurements of the growth rate parameter, fσ8, from redshift-space distortions (RSD). This composite sample is the most constraining of its kind and allows us to perform a comprehensive assessment of the cosmological model after two decades of dedicated spectroscopic observation. We show that the BAO data alone are able to rule out dark-energy-free models at more than eight standard deviations in an extension to the flat, ΛCDM model that allows for curvature. When combined with Planck Cosmic Microwave Background (CMB) measurements of temperature and polarization, under the same model, the BAO data provide nearly an order of magnitude improvement on curvature constraints relative to primary CMB constraints alone. Independent of distance measurements, the SDSS RSD data complement weak lensing measurements from the Dark Energy Survey (DES) in demonstrating a preference for a flat ΛCDM cosmological model when combined with Planck measurements. The combined BAO and RSD measurements indicate σ8=0.85±0.03, implying a growth rate that is consistent with predictions from Planck temperature and polarization data and with General Relativity. When combining the results of SDSS BAO and RSD, Planck, Pantheon Type Ia supernovae (SNe Ia), and DES weak lensing and clustering measurements, all multiple-parameter extensions remain consistent with a ΛCDM model. Regardless of cosmological model, the precision on each of the three parameters, ωΛ, H0, and σ8, remains at roughly 1%, showing changes of less than 0.6% in the central values between models. In a model that allows for free curvature and a time-evolving equation of state for dark energy, the combined samples produce a constraint ωk=-0.0022±0.0022. The dark energy constraints lead to w0=-0.909±0.081 and wa=-0.49-0.30+0.35, corresponding to an equation of state of wp=-1.018±0.032 at a pivot redshift zp=0.29 and a Dark Energy Task Force Figure of Merit of 94. The inverse distance ladder measurement under this model yields H0=68.18±0.79 km s-1 Mpc-1, remaining in tension with several direct determination methods; the BAO data allow Hubble constant estimates that are robust against the assumption of the cosmological model. In addition, the BAO data allow estimates of H0 that are independent of the CMB data, with similar central values and precision under a ΛCDM model. Our most constraining combination of data gives the upper limit on the sum of neutrino masses at mν

This study aims to evaluate the effectiveness of a family support program, community-based dementia caregiver intervention (CDCI), among family caregivers of people with dementia compared with a control group (no intervention).Patients and Methods: This study is a quasi-experimental, non-randomized controlled trial conducted in six dementia relief centers of a community healthcare center in Korea. Family caregivers of 83 patients with dementia were recruited; of these 78 were included in the final study, with 40 in the intervention group and 38 in the control group. Analysis of covariance (ANCOVA) was used to compare the mean difference in the scores of the total short-form Zarit Burden Interview (SZBI), personal strain, role strain, depression, and attitude between the groups.Results: Compared with controls, in the intervention group, the adjusted mean score of personal strain (F = 4.353, t = 0.041) and attitude toward dementia (F = 10.284, t = 0.002) differed significantly after the intervention, with a small to moderate effect. There was no significant difference in the total SZBI, role strain, or depression mean score.Conclusion: The findings suggest that CDCI may be an effective intervention strategy to reduce personal strain and enhance the attitudes of family caregivers of people with dementia.Keywords: community-based intervention, caregiver burden, dementia, family support program, family caregiver

We analyse the clustering of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spectroscopic Survey Data Release 14 quasar sample (DR14Q).We measure the redshift space distortions using the power-spectrum monopole, quadrupole, and hexadecapole inferred from 148 659 quasars between redshifts 0.8 and 2.2, covering a total sky footprint of 2112.9 deg2. We constrain the logarithmic growth of structure times the amplitude of dark matter density fluctuations, fσ8, and the Alcock-Paczynski dilation scales that allow constraints to be placed on the angular diameter distance DA(z) and the Hubble H(z) parameter. At the effective redshift of zeff = 1.52, fσ8(zeff) = 0.420 ± 0.076, H(zeff) = [162 ± 12] (r sfid/rs) kms-1 Mpc-1, and DA(zeff) = [1.85 ± 0.11] × 103 (rs/r sfid) Mpc, where rs is the comoving sound horizon at the baryon drag epoch and the superscript 'fid' stands for its fiducial value. The errors take into account the full error budget, including systematics and statistical contributions. These results are in full agreement with the current Λ-Cold Dark Matter cosmological model inferred from Planck measurements. Finally, we compare our measurements with other eBOSS companion papers and find excellent agreement, demonstrating the consistency and complementarity of the different methods used for analysing the data.

We present measurements of the Baryon Acoustic Oscillation (BAO) scale in redshift-space using the clustering of quasars. We consider a sample of 147 000 quasars from the extended Baryon Oscillation Spectroscopic Survey (eBOSS) distributed over 2044 square degrees with redshifts 0.8 < z < 2.2 and measure their spherically averaged clustering in both configuration and Fourier space. Our observational data set and the 1400 simulated realizations of the data set allow us to detect a preference for BAO that is greater than 2.8σ. We determine the spherically averaged BAO distance to z = 1.52 to 3.8 per cent precision: DV (z = 1.52) = 3843 ± 147 (rd/rd,fid) Mpc. This is the first time the location of the BAO feature has been measured between redshifts 1 and 2. Our result is fully consistent with the prediction obtained by extrapolating the Planck flatΛCDMbest-fitting cosmology. All of our results are consistent with basic large-scale structure (LSS) theory, confirming quasars to be a reliable tracer of LSS, and provide a starting point for numerous cosmological tests to be performed with eBOSS quasar samples. We combine our result with previous, independent, BAO distance measurements to construct an updated BAO distance-ladder. Using these BAO data alone and marginalizing over the length of the standard ruler, we find ΩΛ > 0 at 6.6s significance when testing a ΛCDM model with free curvature.

We present cosmological results from the final galaxy clustering data set of the Baryon Oscillation Spectroscopic Survey, part of the Sloan Digital Sky Survey III. Our combined galaxy sample comprises 1.2 million massive galaxies over an effective area of 9329 deg2 and volume of 18.7 Gpc3, divided into three partially overlapping redshift slices centred at effective redshifts 0.38, 0.51 and 0.61. We measure the angular diameter distance DM and Hubble parameterHfrom the baryon acoustic oscillation (BAO) method, in combinationwith a cosmic microwave background prior on the sound horizon scale, after applying reconstruction to reduce non-linear effects on the BAO feature. Using the anisotropic clustering of the pre-reconstruction density field, we measure the product DMH from the Alcock-Paczynski (AP) effect and the growth of structure, quantified by fσ8(z), from redshift-space distortions (RSD). We combine individual measurements presented in seven companion papers into a set of consensus values and likelihoods, obtaining constraints that are tighter and more robust than those from any one method; in particular, the AP measurement from sub-BAO scales sharpens constraints from post-reconstruction BAOs by breaking degeneracy between DM and H. Combined with Planck 2016 cosmic microwave background measurements, our distance scale measurements simultaneously imply curvature ωK = 0.0003 ± 0.0026 and a dark energy equation-of-state parameter ω =-1.01 ± 0.06, in strong affirmation of the spatially flat cold dark matter (CDM) model with a cosmological constant (ΛCDM). Our RSD measurements of fσ8, at 6 per cent precision, are similarly consistent with this model. When combined with supernova Ia data, we find H0 = 67.3 ± 1.0 kms-1 Mpc-1 even for our most general dark energy model, in tension with some direct measurements. Adding extra relativistic species as a degree of freedom loosens the constraint only slightly, to H0 = 67.8 ± 1.2 kms-1 Mpc-1. Assuming flat ΛCDM, we find ωm = 0.310 ± 0.005 and H0 = 67.6 ± 0.5 kms-1 Mpc-1, and we find a 95 per cent upper limit of 0.16 eV c-2 on the neutrino mass sum.

We present a measurement of the linear growth rate of structure, f, from the Sloan Digital Sky Survey III (SDSS-III) Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 12 (DR12) using convolution Lagrangian perturbation theory (CLPT) with Gaussian streaming redshift space distortions (GSRSD) to model the two-point statistics of BOSS galaxies in DR12. The BOSS-DR12 data set includes 1198 006 massive galaxies spread over the redshift range 0.2 < z < 0.75. These galaxy samples are categorized in three redshift bins. Using CLPT-GSRSD in our analysis of the combined sample of the three redshift bins, we report measurements of fσ8 for the three redshift bins. We find fσ8 = 0.430 ± 0.054 at zeff = 0.38, fσ8 = 0.452 ± 0.057 at zeff = 0.51 and fσ8 = 0.457 ± 0.052 at zeff = 0.61. Our results are consistent with the predictions of Planck Λ cold dark matter-general relativity. Our constraints on the growth rates of structure in the Universe at different redshifts serve as a useful probe, which can help distinguish between a model of the Universe based on dark energy and models based on modified theories of gravity. This paper is part of a set that analyses the final galaxy clustering data set from BOSS. The measurements and likelihoods presented here are combined with others in Alam et al., to produce the final cosmological constraints from BOSS.

We present the large-scale three-point correlation function (3PCF) of the Sloan Digital Sky Survey DR12 Constant stellar Mass (CMASS) sample of 777 202 Luminous Red Galaxies, the largest-ever sample used for a 3PCF or bispectrum measurement. We make the first high-significance (4.5σ) detection of baryon acoustic oscillations (BAO) in the 3PCF. Using these acoustic features in the 3PCF as a standard ruler, we measure the distance to z = 0.57 to 1.7 per cent precision (statistical plus systematic). We find DV =2024±29 Mpc (stat)±20 Mpc (sys) for our fiducial cosmology (consistent with Planck 2015) and bias model. This measurement extends the use of the BAO technique from the twopoint correlation function (2PCF) and power spectrum to the 3PCF and opens an avenue for deriving additional cosmological distance information from future large-scale structure redshift surveys such as DESI. Our measured distance scale from the 3PCF is fairly independent from that derived from the pre-reconstruction 2PCF and is equivalent to increasing the length of BOSS by roughly 10 per cent; reconstruction appears to lower the independence of the distance measurements. Fitting a model including tidal tensor bias yields a moderatesignificance (2.6σ) detection of this bias with a value in agreement with the prediction from local Lagrangian biasing.

We present a Bayesian phase-space reconstruction of the cosmic large-scale matter density and velocity fields from the Sloan Digital Sky Survey-III Baryon Oscillations Spectroscopic Survey Data Release 12 CMASS galaxy clustering catalogue. We rely on a given ∧ cold dark matter cosmology, a mesh resolution in the range of 6-10 h-1 Mpc, and a lognormal-Poisson model with a redshift-dependent non-linear bias. The bias parameters are derived from the data and a general renormalized perturbation theory approach. We use combined Gibbs and Hamiltonian sampling, implemented in the ARGO code, to iteratively reconstruct the darkmatter density field and the coherent peculiar velocities of individual galaxies, correcting hereby for coherent redshift space distortions. Our tests relying on accurate N-body-based mock galaxy catalogues show unbiased real space power spectra of the non-linear density field up to k ~ 0.2 h Mpc-1, and vanishing quadrupoles down to r ~ 20 h-1 Mpc. We also demonstrate that the non-linear cosmic web can be obtained from the tidal field tensor based on the Gaussian component of the reconstructed density field. We find that the reconstructed velocities have a statistical correlation coefficient compared to the true velocities of each individual lightcone mock galaxy of r ~ 0.68 including about 10 per cent of satellite galaxies with virial motions (about r = 0.75 without satellites). The power spectra of the velocity divergence agree well with theoretical predictions up to k ~ 0.2 h Mpc-1. This work will be especially useful to improve, for example, baryon acoustic oscillation reconstructions, kinematic Sunyaev- Zeldovich, integrated Sachs-Wolfe measurements or environmental studies.

We analyse the baryon acoustic oscillation (BAO) signal of the final Baryon Oscillation Spectroscopic Survey (BOSS) data release (DR12). Our analysis is performed in the Fourier space, using the power spectrum monopole and quadrupole. The data set includes 1198 006 galaxies over the redshift range 0.2 < z < 0.75.We divide this data set into three (overlapping) redshift bins with the effective redshifts zeff = 0.38, 0.51 and 0.61. We demonstrate the reliability of our analysis pipeline using N-body simulations as well as ~1000 MultiDark- Patchy mock catalogues that mimic the BOSS-DR12 target selection. We apply density field reconstruction to enhance the BAO signal-to-noise ratio. By including the power spectrum quadrupole we can separate the line of sight and angular modes, which allows us to constrain the angular diameter distance DA(z) and the Hubble parameter H(z) separately. We obtain two independent 1.6 and 1.5 per cent constraints on DA(z) and 2.9 and 2.3 per cent constraints on H(z) for the low (zeff = 0.38) and high (zeff = 0.61) redshift bin, respectively. We obtain two independent 1 and 0.9 per cent constraints on the angular averaged distance DV(z), when ignoring the Alcock-Paczynski effect. The detection significance of the BAO signal is of the order of 8σ (post-reconstruction) for each of the three redshift bins. Our results are in good agreement with the Planck prediction within Λ cold dark matter. This paper is part of a set that analyses the final galaxy clustering data set from BOSS. The measurements and likelihoods presented here are combined with others in Alam et al. to produce the final cosmological constraints from BOSS.

We present baryon acoustic oscillation (BAO) scale measurements determined from the clustering of 1.2 million massive galaxies with redshifts 0.2 < z < 0.75 distributed over 9300 deg2, as quantified by their redshift-space correlation function. In order to facilitate these measurements, we define, describe, and motivate the selection function for galaxies in the final data release (DR12) of the SDSS III Baryon Oscillation Spectroscopic Survey (BOSS). This includes the observational footprint, masks for image quality and Galactic extinction, and weights to account for density relationships intrinsic to the imaging and spectroscopic portions of the survey. We simulate the observed systematic trends in mock galaxy samples and demonstrate that they impart no bias on BAO scale measurements and have a minor impact on the recovered statistical uncertainty. We measure transverse and radial BAO distance measurements in 0.2 < z < 0.5, 0.5 < z < 0.75, and (overlapping) 0.4 < z < 0.6 redshift bins. In each redshift bin, we obtain a precision that is 2.7 per cent or better on the radial distance and 1.6 per cent or better on the transverse distance. The combination of the redshift bins represents 1.8 per cent precision on the radial distance and 1.1 per cent precision on the transverse distance. This paper is part of a set that analyses the final galaxy clustering data set from BOSS. The measurements and likelihoods presented here are combined with others in Alam et al. to produce the final cosmological constraints from BOSS.

We describe the redmonster automated redshift measurement and spectral classification software designed for the extended Baryon Oscillation Spectroscopic Survey (eBOSS) of the Sloan Digital Sky Survey IV (SDSS-IV). We describe the algorithms, the template standard and requirements, and the newly developed galaxy templates to be used on eBOSS spectra. We present results from testing on early data from eBOSS, where we have found a 90.5% automated redshift and spectral classification success rate for the luminous red galaxy sample (redshifts 0.6 ≲ z ≲ 1.0). The redmonster performance meets the eBOSS cosmology requirements for redshift classification and catastrophic failures and represents a significant improvement over the previous pipeline. We describe the empirical processes used to determine the optimum number of additive polynomial terms in our models and an acceptable δX2rthreshold for declaring statistical confidence. Statistical errors on redshift measurement due to photon shot noise are assessed, and we find typical values of a few tens of km s-1. An investigation of redshift differences in repeat observations scaled by error estimates yields a distribution with a Gaussian mean and standard deviation of μ ∼ 0.01 and σ ∼ 0.65, respectively, suggesting the reported statistical redshift uncertainties are over-estimated by ∼54%. We assess the effects of object magnitude, signal-to-noise ratio, fiber number, and fiber head location on the pipeline's redshift success rate. Finally, we describe directions of ongoing development.

We describe the algorithm used to select the luminous red galaxy (LRG) sample for the extended Baryon Oscillation Spectroscopic Survey (eBOSS) of the Sloan Digital Sky Survey IV (SDSS-IV) using photometric data from both the SDSS and the Wide-field Infrared Survey Explorer. LRG targets are required to meet a set of color selection criteria and have z-band and i-band MODEL magnitudes z < 19.95 and 19.9 < i < 21.8, respectively. Our algorithm selects roughly 50 LRG targets per square degree, the great majority of which lie in the redshift range 0.6 < z < 1.0 (median redshift 0.71). We demonstrate that our methods are highly effective at eliminating stellar contamination and lower-redshift galaxies. We perform a number of tests using spectroscopic data from SDSS-III/BOSS ancillary programs to determine the redshift reliability of our target selection and its ability to meet the science requirements of eBOSS. The SDSS spectra are of high enough signal-to-noise ratio that at least ∼89% of the target sample yields secure redshift measurements. We also present tests of the uniformity and homogeneity of the sample, demonstrating that it should be clean enough for studies of the large-scale structure of the universe at higher redshifts than SDSS-III/BOSS LRGs reached.

We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave background (CMB) data and a recent reanalysis of Type Ia supernova (SN) data. In particular, we take advantage of high-precision BAO measurements from galaxy clustering and the Lyman-α forest (LyaF) in the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS). Treating the BAO scale as an uncalibrated standard ruler, BAO data alone yield a high confidence detection of dark energy; in combination with the CMB angular acoustic scale they further imply a nearly flat universe. Adding the CMB-calibrated physical scale of the sound horizon, the combination of BAO and SN data into an "inverse distance ladder" yields a measurement of H0=67.3±1.1 km s-1 Mpc-1, with 1.7% precision. This measurement assumes standard prerecombination physics but is insensitive to assumptions about dark energy or space curvature, so agreement with CMB-based estimates that assume a flat ΛCDM cosmology is an important corroboration of this minimal cosmological model. For constant dark energy (Λ), our BAO+SN+CMB combination yields matter density Ωm=0.301±0.008 and curvature Ωk=-0.003±0.003. When we allow more general forms of evolving dark energy, the BAO+SN+CMB parameter constraints are always consistent with flat ΛCDM values at ≈1σ. While the overall χ2 of model fits is satisfactory, the LyaF BAO measurements are in moderate (2-2.5σ) tension with model predictions. Models with early dark energy that tracks the dominant energy component at high redshift remain consistent with our expansion history constraints, and they yield a higher H0 and lower matter clustering amplitude, improving agreement with some low redshift observations. Expansion history alone yields an upper limit on the summed mass of neutrino species, mν

As part of the Sloan Digital Sky Survey (SDSS) IV the extended Baryon Oscillation Spectroscopic Survey (eBOSS) will improve measurements of the cosmological distance scale by applying the Baryon Acoustic Oscillation (BAO) method to quasar samples. eBOSS will adopt two approaches to target quasars over 7500 deg2. First, a "CORE" quasar sample will combine the optical selection in ugriz using a likelihood-based routine called XDQSOz, with a mid-IR-optical color cut. eBOSS CORE selection (to g < 22 or r < 22) should return ∼70 deg-2 quasars at redshifts 0.9 < z < 2.2 and ∼7 deg-2z > 2.1 quasars. Second, a selection based on variability in multi-epoch imaging from the Palomar Transient Factory should recover an additional ∼3-4 deg-2z > 2.1 quasars to g < 22.5. A linear model of how imaging systematics affect target density recovers the angular distribution of eBOSS CORE quasars over 96.7% (76.7%) of the SDSS north (south) Galactic Cap area. The eBOSS CORE quasar sample should thus be sufficiently dense and homogeneous over 0.9 < z < 2.2 to yield the first few-percent-level BAO constraint near eBOSS quasars at z > 2.1 will be used to improve BAO measurements in the Lyα Forest. Beyond its key cosmological goals, eBOSS should be the next-generation quasar survey, comprising >500,000 new quasars and >500,000 uniformly selected spectroscopically confirmed 0.9 < z < 2.2 quasars. At the conclusion of eBOSS, the SDSS will have provided unique spectra for more than 800,000 quasars.

We present measurements of the angular diameter distance to and Hubble parameter at z = 0.57 from the measurement of the baryon acoustic peak in the correlation of galaxies from the Sloan Digital Sky Survey III Baryon Oscillation Spectroscopic Survey. Our analysis is based on asample from Data Release 9 of 264 283 galaxies over 3275 square degrees in the redshift range 0.43 < z < 0.70. We use two different methods to provide robust measurement of the acoustic peak position across and along the line of sight in order to measure the cosmological distance scale. We find DA(0.57) = 1408 ± 45 Mpc and H(0.57) = 92.9 ± 7.8 km s-1 Mpc-1 for our fiducial value of the sound horizon. These results from the anisotropic fitting are fully consistent with the analysis of the spherically averaged acoustic peak position presented in Anderson et al. Our distance measurements are a close match to the predictions of the standard cosmological model featuring a cosmological constant and zero spatial curvature. © 2014 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations (BAO) in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 (DR11) sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released DR9 and DR10 samples. Assuming a concordance Λ cold dark matter (ΛCDM) cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = (1264 ± 25 Mpc)(rd/rd,fid) at z = 0.32 and DV = (2056 ± 20 Mpc)(rd/rd,fid) at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = (1421 ± 20 Mpc)(rd/rd,fid) and H = (96.8 ± 3.4 kms-1 Mpc-1)(rd,fid/rd). Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

We perform the first fit to the anisotropic clustering of Sloan Digital Sky Survey III CMASS data release 10 galaxies on scales of ~0.8-32 h-1 Mpc.Astandard halo occupation distribution model evaluated near the best-fitting Planck ? cold dark matter (?CDM) cosmology provides a good fit to the observed anisotropic clustering, and implies a normalization for the peculiar velocity field of M~2 × 1013h-1 M haloes of fσ8(z = 0.57) = 0.450 ± 0.011. Since this constraint includes both quasi-linear and non-linear scales, it should severely constrain modified gravity models that enhance pairwise infall velocities on these scales. Though model dependent, our measurement represents a factor of 2.5 improvement in precision over the analysis of DR11 on large scales, fσ8(z = 0.57) = 0.447 ± 0.028, and is the tightest single constraint on the growth rate of cosmic structure to date. Our measurement is consistent with the Planck ?CDM prediction of 0.480 ± 0.010 at the ~1.9σ level. Assuming a halo mass function evaluated at the best-fitting Planck cosmology,we also find that 10 per cent of CMASS galaxies are satellites in haloes of mass M ~ 6 × 1013 h-1 M. While none of our tests and model generalizations indicate systematic errors due to an insufficiently detailed model of the galaxy-halo connection, the precision of these first results warrant further investigation into the modelling uncertainties and degeneracies with cosmological parameters.

Methods: Of 3,200 eligible subjects, 2,936 (91.8%) adolescents were recruited from four elementary schools (6th grade, age range: 10–12 years), five middle schools (8th grade, age range: 13–14 years), and three high schools (10th grade, age range: 15–17 years) located in the Jeju Special Self-Governing Province, Republic of Korea. This study used a self-administered questionnaire to collect data on sociodemographic characteristics and experiences of bullying victimization and employed the Korean form of the Children’s Depression Inventory to evaluate depressive symptoms. Results: Of the total sample of 2,936 students, 1,689 were boys (57.5%) and 1,247 were girls (42.5%). The prevalence of bullying victimization by age group was as follows: 10–12 years, 9.5%; 13–14 years, 8.3%; and 15–17 years, 6.4%. A significant difference in the prevalence of bullying victimization was observed by sex (boys: 45.0%, girls: 55.0%). Overall, the prevalence decreased with age. After adjusting for age and sex, bullying victimization was significantly associated with lower socioeconomic status (odds ratio [OR] =1.67; 95% confidence interval [CI] 1.04–2.67), lower than average academic achievement (OR =1.77; 95% CI 1.25–2.50), more depressive symptoms (OR =1.88; 95% CI 1.38–2.55), and poorer perceived relationship with parents (OR =1.46; 95% CI 1.00–2.14). Conclusion: Our findings will provide researchers and public health practitioners with data on the prevalence of bullying victimization and help to identify the risk factors for later behavioral and emotional problems.

Depressive symptoms were assessed using the Korean version of the Edinburgh Postnatal Depression Scale. Bipolarity was assessed using the Korean version of the Mood Disorder Questionnaire.Results: Nineteen participants (22.6%) had positive Mood Disorder Questionnaire scores, suggesting the presence of bipolarity, and were significantly more likely to score high on the Edinburgh Postnatal Depression Scale. Antenatal depression was associated with bad marital communication and marital dissatisfaction.Conclusion: These results suggest that spousal interactions play a significant role in antenatal depression, and pregnant women with bipolarity may be more depressed than those without bipolarity.Keywords: antenatal depression, bipolarity, pregnancy, Korea

Jong-Hyun Jeong,1 Won-Myong Bahk,1 Young Sup Woo,1 Ho-Jun Seo,1 Seung-Chul Hong,1 Duk-In Jon,2 Kyung Joon Min,3 Bo-Hyun Yoon41Department of Psychiatry, College of Medicine, The Catholic of University of Korea, Seoul, 2Department of Psychiatry, College of Medicine, Hallym University, Anyang, 3Department of Neuropsychiatry, College of Medicine, Chung-Ang University, Seoul, 4Naju National Hospital, Naju, KoreaPurpose: To evaluate and compare the therapeutic efficacy of quetiapine in bipolar I and II depression patients in the clinical setting.Patients and methods: This was an 8-week, multicenter, open-label, observational study for bipolar depression. The dosage of quetiapine was flexible, and concomitant medications were permitted on clinician's judgments. A total of 1097 patients were enrolled, and 764 bipolar depression patients who exhibited good therapeutic compliance (>75% compliance rate) were analyzed.Results: Clinical Global Impression – Bipolar scale and Montgomery–Asberg Depression Rating Scale scores were significantly improved at weeks four and eight compared with the baseline scores. At the end of the 8-week study, the response rate was 58.9%, and the remission rate was 42.1%. However, there were no significant differences in the response and remission rates between bipolar I and II disorder (BD-I and BD-II) patients (response rate 60.1% versus 56.3%; remission rate 44.5% versus 37.0%). Montgomery–Asberg Depression Rating Scale score at baseline (β = 0.612, P < 0.001), duration of current episode (β = −0.152, P = 0.001), and presence of remission on previous episode (β = 0.111, P = 0.012) were significantly associated with improvements in depressive symptoms. Fatigue (16.0%), somnolence (14.9%), and manic/hypomanic switching (0.6% at week four, 0.3% at week eight) were observed throughout the study period.Conclusion: The results of this study suggest that quetiapine improves depressive symptoms in BD-I and BD-II patients with a minimal incidence of manic switching. The therapeutic efficacy of quetiapine increased with time. Quetiapine could be an effective and safe modality for the treatment of BD-I and BD-II.Keywords: bipolar depression, quetiapine, therapeutic efficacy, observational study

This study evaluated clinical characteristics and suicidality of patients with anxious depression in a large cohort of samples. Data were collected from 1003 patients who were depressed. A total of 461 patients were diagnosed with anxious depression and 542 were diagnosed with nonanxious depression. After adjusting for the severity of depression, those in the anxious depression group had significantly younger onset age, had been suffering from depression for a longer period, were more likely to experience a recurrence, and obtained lower scores on a scale assessing quality of life. The anxious depression group was characterized by a significantly higher proportion of individuals reporting significant suicidal ideation and previous suicide attempts, and those in this group tended to obtain higher scores on the Scale for Suicide Ideation. The present findings that were drawn from detailed evaluation of suicidality strongly support previous results assessed only with the help of clinical reports. More attention should be paid to assess suicide risk in these patients. [ABSTRACT FROM AUTHOR]

Purpose: Although the significance of health literacy (HL) in fall prevention strategies is growing, limited knowledge is available regarding the relationship, impact, and role of HL in falls. This scoping review aimed to explore and synthesize the current evidence regarding the role of HL in enhancing fall prevention in hospital and community settings., Methods: We adhered to the Joanna Briggs Institute manual and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews. PubMed, CINAHL, EMBASE, and the Cochrane Library were searched until November 2023 using Medical Subject Headings and text words. Studies related to HL and falls, regardless of study design, were considered eligible., Results: We screened 99,249 records, of which 27 were included: 12 interventional studies, seven observational studies, four qualitative studies, and four mixed methods studies. Two-thirds of the studies were conducted in community-based settings. Four observational studies reported that HL was associated with fall-related outcome including fall incidence. Although intervention studies did not encompass all elements of HL based on the Health Literacy Framework, eight out of 12 intervention studies reported effect of HL-embedded fall prevention interventions, and HL was effective in fall-related outcomes including fall incidence in six studies. Three of 14 studies reported the measurement properties of fall-related HL. While HL can be increased through tailored information, verbal debriefing, interactive communication, and culturally adapted interventions, low HL impedes the understanding of education, engaging interventions, and using technological devices in implementing fall prevention interventions in qualitative and mixed methods studies., Conclusion: This scoping review suggests that nurses need to recognize and assess patients' HL as a potential risk factor for falls and implement fall prevention interventions based on the HL level of participants. Further research is required to develop culturally adapted and fall-relevant HL measures applicable to various vulnerable populations and settings., (Copyright © 2024. Published by Elsevier B.V.)

Background: Latrophilin-2 (Lphn2), an adhesive GPCR (G protein-coupled receptor), was found to be a specific marker of cardiac progenitors during the differentiation of pluripotent stem cells into cardiomyocytes or during embryonic heart development in our previous studies. Its role in adult heart physiology, however, remains unclear., Methods: The embryonic lethality resulting from Lphn2 deletion necessitates the establishment of cardiomyocyte-specific, tamoxifen-inducible Lphn2 knockout mice, which was achieved by crossing Lphn2  flox/flox mice with mice having MerCreMer (tamoxifen-inducible Cre [Cyclization recombinase] recombinase) under the α-myosin heavy chain promoter., Results: Tamoxifen treatment for several days completely suppressed Lphn2 expression, specifically in the myocardium, and induced the dilated cardiomyopathy (D-CMP) phenotype with serious arrhythmia and sudden death in a short period of time. Transmission electron microscopy showed mitochondrial abnormalities, blurred Z-discs, and dehiscent myofibrils. The D-CMP phenotype, or heart failure, worsened during myocardial infarction. In a mechanistic study of D-CMP, Lphn2 knockout suppressed PGC-1α (Peroxisome proliferator-activated receptor gamma coactivator 1-alpha) and mitochondrial dysfunction, leading to the accumulation of reactive oxygen species and the global suppression of junctional molecules, such as N-cadherin (adherens junction), DSC-2 (desmocollin-2; desmosome), and connexin-43 (gap junction), leading to the dehiscence of cardiac myofibers and serious arrhythmia. In an experimental therapeutic trial, activators of p38-MAPK (p38 mitogen-activated protein kinases), which is a downstream signaling molecule of Lphn2, remarkably rescued the D-CMP phenotype of Lphn2 knockout in the heart by restoring PGC-1α and mitochondrial function and recovering global junctional proteins., Conclusions: Lphn2 is a critical regulator of heart integrity by controlling mitochondrial functions and cell-to-cell junctions in cardiomyocytes. Its deficiency leads to D-CMP, which can be rescued by activators of the p38-MAPK pathway., Competing Interests: None.

An encouraging outcome was described for the use of modified Furlow small double-opposing Z-plasty (sDOZ) using the medial incision (MIsDOZ) approach in repair of Veau type I cleft palate. This retrospective study assessed early results of using extended indication criterion of MIsDOZ for the management of consecutive non-syndromic patients with Veau II cleft palate treated by a single surgeon. Bardach two-flap plus sDOZ (two-flap approach) or medial incision approach with a tension-driven stepwise application of lateral palatal incisions (soft palate only, von Langenbeck type, or two-flap type) were applied. Surgical (age, cleft width, operative time, hospital stay, and complication)- and auditory-perceptual assessment-related data were collected. Two-flap approach (n = 21) demonstrated a significantly (p < 0.001) increased operative time (132.8 ± 12.2 versus 114.8 ± 19.9 min, respectively) and higher use of lateral incisions (100% versus 44.4%) than medial incision approach (n = 27), with no significant (p > 0.05) difference for age at surgery (13.0 ± 6.1 versus 13.6 ± 5.8 months), cleft width (8.5 ± 4.1 versus 8.7 ± 3.8 mm), hospital stay (1.0 ± 0 versus 1.0 ± 0 day), and complication (0% versus 0%) and hypernasality (9.5% versus 7.4%) rates. In conclusion, the medial incision approach for Veau II cleft repair resulted in reduced need for lateral palatal incision with no increase of complication or hypernasality rates., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this article., (Copyright © 2024 European Association for Cranio-Maxillo-Facial Surgery.

Background: There is increasing evidence that probiotics are effective in treating allergic rhinitis (AR), while some controversies remain. This study was performed to evaluate the therapeutic effect and safety of a mixture of Bifidobacterium longum and Lactobacillus plantarum (NVP-1703) in children with AR., Methods: In a randomized, double-blind, placebo-controlled study, children aged 6 to 19 years with perennial AR were treated with NVP-1703 at a dose of 1 × 10 10 CFU/day or placebo once a day for 4 weeks. Total nasal symptom score (TNSS), nasal symptom duration score (NSDS), quality of life (QoL), allergic inflammatory markers, and safety parameters were evaluated., Results: After 4 weeks of treatment, the TNSS in the NVP-1703 group significantly decreased compared to that in the placebo group ( P = 0.011), both in the morning and the evening ( P = 0.031 and P = 0.004, respectively). The NSDS also significantly decreased in the NVP-1703 group compared to that in the placebo group ( P = 0.018). QoL scores, particularly those related to mouth breathing and itchy nose, showed a significant improvement in the NVP-1703 group compared to the placebo group. The ratios of interleukin (IL)-4/IL-22 and IL-5/IL-22 were significantly reduced in the NVP-1703 group after the treatment compared to the baseline values. No notable adverse events were reported in the NVP-1703 group., Conclusion: Oral administration of a mixture of B. longum and L. plantarum (NVP-1703) improved both AR symptoms and QoL in children with perennial AR, accompanied by decreases in the ratios of T helper 2 cytokines to IL-22., Trial Registration: Clinical Research Information Service Identifier: KCT0002661., Competing Interests: Jang SW, Han SW, and Kang SH are employed by NVP Healthcare Co., Ltd.

Potassium gadolinium phosphates [K 3 Gd 5 (PO 4 ) 6 ] co-doped with Bi 3+ /Sm 3+ phosphors were prepared by traditional solid-state method. Their structure, morphology, luminescence properties, energy transfer, temperature sensing performance and thermal stability have been systematically investigated. The emission and excitation spectra, as well as decay curves were recorded to study the luminescence mechanism. By co-doping Bi 3+ /Sm 3+ , white emission color can be obtained. In addition, the emission intensity ratios of Bi 3+ and Sm 3+ ions present excellent temperature sensing performance in a wide temperature range. The maximum relative sensitivities of K 3 Gd 5 (PO 4 ) 6 doped with Bi 3+ /Sm 3+ can reach to 3.13% K -1 . In addition, K 3 Gd 5 (PO 4 ) 6 :Bi 3+ ,Sm 3+ phosphors exhibit high thermal stability of about 55.3% at 423 K compared to room temperature., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)

Background: The increasing population of cancer survivors poses a significant challenge for healthcare systems globally, necessitating comprehensive post-treatment care to address diverse physical, psychological, and social needs., Objective: This systematic review aims to synthesize and critically evaluate the current evidence concerning the unmet needs for nursing services among cancer survivors, spanning various dimensions of survivorship care., Methods: A systematic search was conducted across major databases, including PubMed, CINAHL, and PsycINFO, to identify relevant studies investigating the unmet needs and health-related quality-of-life (HRQOL) of nursing services led by nurses among cancer survivors. The final search update was conducted in June 2024. Unmet needs dimensions were categorized by the biopsychosocial-spiritual framework., Results: Of the 9503 records searched, 18 studies were included. This review revealed mixed findings in the domains of unmet needs and interventions aimed at addressing them. While nurse-led interventions showed promise in addressing physical and daily living needs, outcomes related to psychological and emotional needs varied across studies. Additionally, nurse-led interventions were effective in addressing patient-clinician communication and health system/information needs, although statistical significance was not consistently observed. HRQOL assessments using general and cancer-specific measures yielded mixed findings., Conclusions: Despite limitations of the risk of bias of included studies and weak study designs for evaluating nurse-led intervention effects for cancer survivors, the findings highlight the potential of nursing practice to significantly contribute to improving unmet needs of physical, psychological, and social perspectives and ultimately improving their HRQOL. However, the impact on the spiritual needs of nursing care services is limited by the low number of studies., Implications for Cancer Survivors: By providing comprehensive support and management, nursing practice can enhance post-treatment outcomes and HRQOL for cancer survivors, contributing to more patient-centered and effective care delivery. More rigorous research considering a biopsychosocial-spiritual perspective to help cancer survivors improve HRQOL is needed., (© 2024.

Background: Due to rapid increases in the number of Korean people with dementia, dementia has become a priority health issue in South Korea. Likewise, the well-being of family caregivers of people with dementia has also become an issue of concern. However, little is known about the resilience of Korean family caregivers because there is a lack of review studies from a Korean cultural perspective about the resilience of family caregivers of people with dementia., Objectives: The purpose of this scoping review was to investigate quantitative studies related to resilience theories, measurement instruments, correlates and resilience interventions for family caregivers of people with dementia., Method: This review was conducted according to the Joanna Briggs Institute based on Arksey and O'Malley. Nine databases were searched to retrieve evidence published in English or Korean between January 2000 and September 2022. Studies with a quantitative research design reporting the resilience of family caregivers of people with dementia based on a resilience theory framework were included., Results: A total of 13 studies were included in this review. All studies used either a modified McCubbin and McCubbin's family stress, adjustment and adaptation model or Walsh's family resilience model. All resilience instruments were used without cross-cultural adaptation. Family adaptation, social support, life satisfaction, family (di)stress and caregiver burden were associated with resilience among family caregivers. A few family resilience-enhancing programmes showed a positive effect on caregiver resilience., Conclusion: This review noted that all the resilience measures documented in this study need to test for cultural adaptation in a Korean context. Further research is required to develop and implement family-based, culturally tailored interventions to effectively enhance Korean resilience for family caregivers of people with dementia., Implications for Practice: Gerontological nurses should include Korean family caregivers in their nursing care and assess whether family caregivers have depression or suicidal thoughts to promote better health outcomes for caregivers and their family members., (© 2024 John Wiley & Sons Ltd.)

Background: The health-related quality of life instrument with 8 items (HINT-8) was developed to measure health-related quality of life (HRQoL) in Korea. However, the HINT-8 has not yet been validated among the family caregivers of people with dementia (PwD)., Design: A cross-sectional pilot study., Objective: The study aimed to examine the convergent and discriminant validity of the HINT-8 among family caregivers of individuals with dementia., Sample: Forty-seven family caregivers of PwD., Measurements: HINT-8 was compared with the 5-level EQ-5D (EQ-5D-5L) to assess its convergent and discriminant validity. Additionally, the association between the two instruments assessing HRQoL was examined using the short-form Bédard-Zarit Burden Interview (SZBI)., Results: The HINT-8 was a promising and valid HRQoL instrument for family caregivers of PwD. There was a significantly high correlation between the overall HINT-8 and EQ-5D-5L indices (r = 0.85, p < .001). The HINT-8 had acceptable psychometric properties compared to the commonly used EQ-5D-5L, as indicated by the subdomains associated with family caregivers' burden measured by the SZBI., Conclusion: Future studies should compare the HINT-8 with existing dementia carer-specific QoL instruments among a larger study sample to enhance its statistical power and confirm its reliability and structural validity., (© 2024 Wiley Periodicals LLC.)

Objective: Obstructive sleep apnea (OSA) is a breathing disorder characterized by recurrent airway obstruction during sleep. Previous western studies have investigated the link between medical disorders and the pathophysiology of OSA. The prevalence and comorbidity rates of OSA; however, vary across different countries and racial groups. This study aimed to delve into medical comorbidities in patients with OSA using a large nationwide healthcare database in Korea., Methods: This nationwide study used the Korean National Health Insurance claims database (2010-2019). The effect of OSA on the incidence of medical disorders was estimated using the Cox proportional hazard ratio (HR) model. The results were reported as crude and adjusted HRs with 95% confidence intervals (CI). Subgroup analysis was conducted by sex and age., Results: In total, 103,785 patients with OSA and 207,570 patients without OSA were included. OSA group had significantly higher HRs for ischemic heart disease and stroke even after adjusting for hypertension, dyslipidemia, and diabetes. The OSA group also showed an increased risk of metabolic syndrome-related diseases, chronic kidney disease, and gastroesophageal reflux disease. Female patients with OSA exhibited notably higher rates of comorbid liver cirrhosis, chronic obstructive pulmonary disease, and asthma. The cardiovascular burden of patients increased in accordance with the patients' age., Conclusion: Korean patients with OSA have a significantly increased risk of cardio-cerebrovascular diseases, which aligns with the previous studies conducted in the western countries. This result holds particular significance as it represents the first nationwide, population-based study conducted in Asia.

Marchantia polymorpha, occupying a basal position in the monophyletic assemblage of land plants, displays a notable expansion of plant U-box (PUB) proteins compared with those in animals. We elucidated the roles of MpPUB9 in regulating salt stress tolerance in M. polymorpha. MpPUB9 expression was rapidly induced by high salinity and dehydration. MpPUB9 possessed an intact U-box domain in the N-terminus. MpPUB9-Citrine localized to punctate structures and was peripherally associated with microsomal membranes. Phenotypic analyses demonstrate that the hyponastic and epinastic thallus growth phenotypes, which were induced by the overexpression and suppression of MpPUB9, may provoke salt stress-resistant and -susceptible phenotypes, respectively. MpPUB9 was also found to directly interact with the exocyst protein MpEXO70.1, leading to its ubiquitination. Under high-salinity conditions, though the stability of MpPUB9 was dramatically increased, MpEXO70.1 showed slightly faster turnover rates. Transcriptome analyses showed that salt treatment and the overexpression of MpPUB9 co-upregulated the genes related to the modulation of H 2 O 2 and cell wall organization. Overall, our results suggest that MpPUB9 plays a crucial role in the positive regulation of salt stress tolerance, resulting from its interaction with MpEXO70.1 and modulating turnover of the protein under high-salt conditions via the coordination of UPS with autophagy., (© 2024 The Author(s).

Objective: : Diagnosing attention-deficit/hyperactivity disorder (ADHD) in adults is often hard. This study aimed to determine differences in absolute EEG power and frontal asymmetry between individuals with ADHD and non-ADHD in young adults aged 18-30 years., Methods: : Young adult (age: 18-30 years) outpatients (n = 103) including ADHD patients (n = 51) and non-ADHD patients (n = 52) were enrolled. QEEG was performed for both groups for each region of the brain. The absolute power of each frequency measured in three frontal regions (Lt., Mid., Rt.) of the scalp area was compared between the two groups. Differences between the two groups including theta/beta ratio were compared. Frontal asymmetries were also evaluated for prefrontal (Fp2-Fp1), middle frontal (F4-F3), lateral frontal (F8-F7) pairs at all frequencies. Correlation analysis was performed for absolute powers, frontal asymmetry, and Stroop tests., Results: : Demographic data, neuropsychological tests, and psychiatric symptoms were not significantly different between the two groups. Delta band was significantly increased while beta band was decreased in the middle frontal area of the ADHD group as compared with those of the non-ADHD group. For frontal asymmetries, all frequencies in the middle frontal area were more rightward in ADHD patients than in non-ADHD patients. Absolute powers in delta, beta band, and frontal asymmetry in all frequencies had correlations with Stroop tests., Conclusion: : This study revealed that ADHD patients had significant differences in absolute powers in delta, beta bands, and frontal asymmetries in all frequencies. Our findings suggest that QEEG can be a helpful tool for diagnosing ADHD in psychiatric patients.

Intermediate rhinoplasty, the correction of cleft lip nose deformities, is performed between the time of primary and secondary rhinoplasties, which is at ~6 years of age. Although intermediate rhinoplasty reduces psychological stress in school-aged children through improvements in appearance, studies on intermediate rhinoplasty are scarce. Hence, in this study, we aimed to evaluate the long-term outcomes of intermediate rhinoplasty in patients with unilateral cleft lip. Twenty-three patients with unilateral cleft lip who underwent intermediate rhinoplasty without primary rhinoplasty from 1997 to 2004 were enrolled in this retrospective study. They were categorized into total, male, and female groups. Photogrammetric analysis of 9 proportional, 5 angular, and 6 nostril-related parameters was performed using photographs that were taken after skeletal maturity had been reached; these parameters were compared with those of normal controls. The cleft group had significantly lower dome-to-columellar ratio, nasal sill ratio, labial-columellar angle, nostril width ratio, nostril height (base) ratio, nostril one-fourth medial part ratio, and nostril area ratio measurement and significantly higher alar width/mouth width ratio, columella height/alar width ratio, nasal tip protrusion/alar base width ratio, nasal dorsum angle, and nostril dimension in the cleft side values than the control group. After intermediate rhinoplasty, significant nasal improvement was achieved, including sufficient nasal tip projection, nasal height, nasal protrusion, and a relatively symmetric nasal tip without tip deviation. Intermediate rhinoplasty may contribute to reducing the psychosocial stress of school-aged children with unilateral cleft lip., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 by Mutaz B.

Background: Submucous cleft palate (SMCP) is a congenital anomaly characterized by the presence of Calnan's triad. However, in clinical practice, it is common for individuals to exhibit one or two anatomical abnormalities within the triad. Furthermore, the definition of SMCP has been diverse and ambiguous in literature. Therefore, this study aimed to analyze the correlation between anatomical abnormalities and development of velopharyngeal insufficiency (VPI)., Methods: We conducted a retrospective analysis of 99 patients referred to our clinic for speech issues or anatomical abnormalities identified during routine oral examinations from January 2012 to June 2023. A single surgeon performed all physical examinations. We evaluated the presence of bony notch, zona pellucida, and bifid uvula, assigned a score to each abnormality, and analyzed their correlation with VPI. The correlation of each of the abnormalities with VPI development was examined, along with the relationship between the number of abnormalities and VPI., Results: Among the 99 patients, 27 were diagnosed with VPI. Only the bony notch had a significant correlation with VPI development. The incidence of VPI tended to increase with the presence of more anatomical abnormalities. VPI occurred in approximately 40% of patients exhibiting all three anatomical abnormalities., Conclusion: The study findings highlight the importance of meticulous intraoral examinations in patients with SMCP and careful monitoring of patients with a bony notch or two or more anatomical abnormalities., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Although microalgae typically serve as prey for jellyfish ephyrae in marine food webs, this study investigated the potential of harmful microalgae to produce detrimental effects on the moon jellyfish Aurelia aurita. Understanding the biological interactions between Aurelia and microalgal species is crucial, particularly considering their common co-occurrence in coastal waters worldwide. We examined the effects of 11 protist strains, comprising seven species of harmful microalgae and two non-toxic microalgae, on A. aurita ephyrae. The rhythmic pulsation behavior of A. aurita was significantly suppressed when exposed to the raphidophytes Heterosigma akashiwo and Chattonella marina var. ovata and the dinoflagellates Amphidinium carterae, Coolia canariensis, and Pfiesteria piscicida. Notably, the media filtrates of all H. akashiwo strains and C. marina var. ovata killed ephyrae, implying a possible extracellular release of chemicals. This study discovered novel interactions between microalgae and jellyfish ephyrae, implying that harmful algal blooms may suppress mass occurrences of Aurelia medusae., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

We aimed to determine the relationship between the use of analgesics prescribed for pain management and the onset and progression of mood disorders using a large-scale cohort database. We calculated hazard ratios (HR) with 95% confidence intervals (CI) for patient risk of developing mood disorders based on age, income, health-related variables, disease history, Charlson comorbidity index, and analgesics prescription behavior (Models 1-3). Additionally, we determined the risk of mood disorder occurrence by age group (Model 4) using a proportional hazards regression model. The age- and income-adjusted HR (Model 1) was 1.8275. The age-, income-, BMI-, and physical-activity-adjusted HR (Model 2) was 1.882. The fully adjusted HR (Model 3) was 1.698. Compared with no analgesic use, nonregular use (HR = 1.386) and regular use (HR = 1.698) was associated with a higher risk of mood disorders. Among patients older than 50 years, those who participated in physical activity (less than five days) had a lower risk of mood disorders than those who did not. This suggests that it may be useful for preventing mood disorders in older cancer survivors. A high risk of comorbidities and regular use of analgesics are risk factors for developing mood disorders. Therefore, our results suggest that cancer survivors with a high risk of comorbidities and a history of regular analgesic use should undergo careful psychiatric consultation.

Background  Velopharyngeal insufficiency (VPI) is a major complication of cleft palate repair. The purpose of this study was to evaluate the incidence and predictive factors of VPI after cleft palate repair based on 27 years of one surgeon's experience. Methods  Medical records were retrospectively reviewed for 652 patients who underwent cleft palate repair between 1995 and 2021. After exclusion of those with other syndromes or developmental disorders, the study included 374 patients with sufficient follow-up until the age of 4 years, when language evaluation was possible. VPI status was categorized through subjective and objective tests into normal, VPI, and borderline. We analyzed potential differences in VPI incidence by multiple factors. Factors with significance were analyzed to confirm the relationships between subvariables. Results  Of the 374 patients, 311 (83.2%) exhibited normal pronunciation, 51 (13.6%) had VPI, and 12 (3.2%) were borderline. Primary cleft palate repair performed after 18 months was associated with a higher incidence of VPI than repair conducted before 18 months ( p  = 0.005). The incidence of VPI was higher in cases of submucous cleft palate than in the other types based on the Veau classification ( p  = 0.011). However, in the multivariable analysis, only the submucous type showed statistically significant results ( p  = 0.026). Conclusion  A total of 374 people underwent primary cleft palate repair, and 13.6% of those with VPI required secondary therapy. The incidence of VPI was relatively high among patients with primary cleft palate repair after 18 months and patients with submucous cleft palate., Competing Interests: Conflict of Interest None declared., (The Author(s).

Introduction: This study investigated the educational needs of integrated care among professionals in the public sector of healthcare and social care services in South Korea., Methods: A cross-sectional secondary data analysis was performed. Original data were obtained from 10 metropolitan communities with a convenience sample of 210 integrated care professionals. The Borich Needs Assessment Model and the Locus for Focus Model were used to examine the priority educational needs of each integrated care professional., Results: This study analyzed the key details of educational needs in integrated care by focusing on the competencies of integrated care approaches for person-centered care, interprofessional collaboration, and community involvement. The core educational needs of community care administrators, care coordinators, healthcare and social care providers, and community health champions, which are common to all professionals, and the specific educational needs for each type of professional were demonstrated, which contained specific content to implement integrated care., Conclusion: This study provides an opportunity to comprehensively understand the educational needs of integrated care professionals based on their competencies. They want better interprofessional cooperation through networking and collaborative strategies. The results of this study may be utilized as fundamental data by future instructors to provide evidence-based education programs., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)

Objective: This narrative review aims to provide a comprehensive assessment of the existing literature on the relationship between hypnotics and dementia, considering both potential link and inconclusive or lack of association., Methods: Data from studies that investigate the association between hypnotic medications and dementia were reviewed. Studies included both cohort studies and systematic reviews, participants with various type of dementia and hypnotics including benzodiazepines (BZDs) and Z-drugs (ZDs)., Results: The existing literatures presents conflicting evidence regarding the association between hypnotics, including BZDs and ZDs, and the risk of dementia. Some studies suggest a potential link between prolonged use of hypnotics and an increased risk of dementia. However, other studies indicate inconclusive or lacking evidence regarding this association. Factors such as study design, sample characteristics, and control of confounding variables contribute to the variability in findings., Conclusion: The relationship between hypnotics and dementia remains complex and controversial. While some studies suggest a potential association, others find inconclusive or conflicting evidence.
