POLYGENIC RISK SCORES ANALYSES IN ANTIPSYCHOTIC-INDUCED WEIGHT GAIN." Schizophrenia Bulletin 46, Supplement_1 (April 2020): S202. http://dx.doi.org/10.1093/schbul/sbaa030.484.

Abstract Background Antipsychotic-induced weight gain (AIWG) is a common and serious side effect with antipsychotic medications, which frequently leads to obesity and metabolic disorders. Previous single-gene analyses have shown an overlap between AIWG and genes associated with obesity and energy homeostasis (e.g., MC4R). However, given the polygenic nature of AIWG, polygenic risk scores (PRS), which combine thousands of common variants weighted by their effect size, provide a novel opportunity to investigate the genetic liability for AIWG. Therefore, we analyzed whether PRSs based on large genome-wide association studies (GWAS) for schizophrenia (SCZ), body mass index (BMI), and diabetes (Type 1 & 2) were associated with AIWG. Methods We used a combined dataset (N=345) from two cohorts, prospectively assessed for AIWG: (1) a subset of the Clinical Antipsychotic Trials in Intervention Effectiveness cohort (CATIE; n=189, Brandl et al., 2016), and (2) the Toronto multi-study cohort (n=156, Brandl et al., 2014). The combined cohort was predominantly male (n=249, 72.2%) and on average 39.3±11.9 years old with a total of 196,787 genetic variants. Our phenotypes of interest included the percentage of BMI/weight change from baseline to end-of-treatment, as well as the presence/absence of significant weight gain (≥7% weight change). We investigated associations between PRSs of SCZ, BMI, and diabetes (Type 1 & 2) and AIWG using regression models, corrected for age, sex, study duration and presence of other risk medication for AIWG. We used the Psychiatric Genomics Consortium schizophrenia GWAS reports to calculate PRSs for SCZ. We used GWAS summary statistics from the GWAS Catalog of BMI and metabolic disorders. For BMI, we used one dataset for BMI (i.e., GCST006900: 2,336,269 variants across up to 700,000). For Type-1 diabetes (T1D), we used one dataset from the GWAS catalog (ID: GCST005536) which included 123,130 variants across 6,683 cases, 12,173 controls, 2,601 affected sibling-pair families, and 69 trios. Likewise, we used three datasets for T2D (i.e., GCST006801: 8,404,432 variants across 4,040 cases and 113,735 controls, GCST007517: 133,871 variants across up to 48,286 cases and up to 250,617 controls, and GCST007518: 133,586 variants across up to 48,286 cases and up to 250,617 controls). Results We observed significant associations with PRS for T1D and percentage BMI/weight change from baseline to the endpoint at P-value threshold=0.0022 (R2=0.02, p=0.03), as well as presence/absence of significant weight gain at PT=0.00015 (R2=0.02, p=0.047). In contrast, we observed no significant associations with PRS for SCZ, BMI, or T2D and AIWG (p>0.05). However, our findings with T1D would not remain significant after correction for multiple testing according to the Bonferroni method. Discussion To the best of our knowledge, this is the first study examining whether PRSs for various metabolic-related phenotypes are associated with AIWG in patients with SCZ. Our findings suggest a possible role for PRS of diabetes type 1 being associated with risk for AIWG. This observation would indicate that (auto)immune processes might be related to AIWG which has not previously been reported. Further studies with larger sample sizes and individuals of various ethnic ancestries are required.

AbstractSince the establishment of the Hipparcos Catalog as the defining source of the optical reference frame, densification beyond its ≈ 120,000 stars has been made possible by the utilization of the Tycho-1 Catalog. The ACT, combining the old Astrographic Catalog (AC) data with the Tycho-1 positions, is the best known example of this. The Tycho-2 consortium, led by E. Høg, has performed new reductions on the Tycho data. This not only has increased the astrometric and photometric accuracies of the original 1 million Tycho-1 stars, but also has added an additional 1.5 million stars. The U.S. Naval Observatory led the effort to compute the proper motions of these 2.5 million stars. They are based not only on the AC data but also include over 140 other ground-based catalogs, all directly reduced to the Hipparcos system. The result of these efforts is the Tycho-2 Catalog, available since February 2000. Positions, proper motions, and BT and VT magnitudes are given for 2.5 million stars. The catalog is 99% complete to V=11.0, and 90% complete to V=11.5. Positional accuracies at the mean epochs vary from < 10 mas for stars V < 9 to just under 100 mas for V > 12. Proper motion accuracies are estimated to be 1.3 mas/year to 3.0 mas/year for the same magnitude ranges. Photometric accuracies range from 0.02 magnitudes for the brightest stars to 0.25 magnitudes for the faintest.

AbstractMajor advances in our understanding of the Universe have historically come from dramatic improvements in our ability to accurately measure astronomical quantities. The astrometric observations obtained by modern digital sky surveys are enabling unprecedentedly massive and robust studies of the kinematics of the Milky Way. For example, the astrometric data from the Sloan Digital Sky Survey (SDSS), together with half a century old astrometry from the Palomar Observatory Sky Survey (POSS), have enabled the construction of a catalog that includes absolute proper motions as accurate as 3 mas/year for about 20 million stars brighter than V=20, and for 80,000 spectroscopically confirmed quasars which provide exquisite error assessment. We discuss here several ongoing studies of Milky Way kinematics based on this catalog. The upcoming next-generation surveys will maintain this revolutionary progress. For example, we show using realistic simulations that the Large Synoptic Survey Telescope (LSST) will measure proper motions accurate to 1 mas/year to a limit 4 magnitude fainter than possible with SDSS and POSS catalogs, or with the Gaia survey. LSST will also obtain geometric parallaxes with accuracy similar to Gaia's at its faint end (0.3 mas at V=20), and extend them to V=24 with an accuracy of 3 mas. We discuss the impact that these LSST measurements will have on studies of the Milky Way kinematics, and potential synergies with the Gaia survey.

The characterization of agrarian structures in contemporary underdeveloped countries has been haunting social scientists for a long time. As in Latin America and India, from the late sixties onwards a strong controversy emerged among Marxists in Turkey concerning the question of why capitalism had not transformed rural structures in Turkey (J. Harris, 1982; R. L. Harris, 1978; Aydın 1986). The question of capitalist transformation of the countryside occupied the minds of classical Marxist thinkers like Kautsky, Lenin, Luxembourg at the end of the 19th century and the beginning of the 20th century.

Full textAbstract:
Aims. Questions of how massive quiescent galaxies rapidly assembled and how abundant they are at high redshift are increasingly important in the study of galaxy formation. Looking at these systems can shed light on the processes of galaxy mass assembly and quenching of the star formation at early epochs. In order to address these questions, we aim to identify and characterize massive quiescent galaxies from z ∼ 2.5 out to the highest redshifts at which these systems can be found. The final purpose is to compare the results with the predictions of state-of-the-art semi-analytical models of galaxy formation and evolution. Methods. We defined observer-frame color–color diagrams to optimally select quiescent galaxies at z > 2.5 and applied them to the COSMOS2015 catalog. We refined the spectral energy distribution (SED) fitting analysis for the selected candidates to confirm their quiescent nature, then derived their number density, mass density, and stellar mass functions. Finally, we compared the results with previous observations and some current semi-analytic models. Results. We selected candidates for quiescent galaxies in the redshift range 2.5 ≲ z ≲ 4.5 from the COSMOS2015 catalog by means of two color–color diagrams. The additional SED fitting analysis allowed us to select 128 galaxies, consistent with being massive (log(M*/M⊙)≥10.6), old (ages ≳0.5 Gyr), and quiescent (log(sSFR [yr−1]) ≤ −10.5) objects at high redshift (2.5 < z < 4.5). Their number and mass densities are in fair agreement with previous observations and, if confirmed, show a discrepancy with current semi-analytical models of galaxy formation and evolution, that underpredict the number of massive quiescent systems up to a factor of ∼12 at 2.5 ≤ z < 3.0 and ∼10 at z ∼ 4.0. The evolution of the stellar mass functions (SMFs) of these systems is similar to previous estimates and indicates a disagreement with models, particularly with regard to the shape of the SMF. Conclusions. The present results add further evidence to the possibility that massive and quiescent galaxies can exist out to at least z ∼ 4. If future spectroscopic observations carried out with, for example, the James Webb Space Telecope (JWST), confirm the substantial presence of such a population, further work on modeling the stellar mass assembly, as well as supermassive black hole accretion and feedback processes at early cosmic epochs, is needed to understand how these systems formed, evolved, and quenched their star formation.

Context. Developing high-precision ephemerides for Neptunian satellites requires not only the continuation of observing campaigns but also the collection and improvement of existing observations. So far, no complete catalogs of observations of Neptunian satellites are available. Aims. We aim to provide new, precise positions, and to compile a catalog including all available ground-based astrometric observations of Neptunian satellites. The observations are tabulated in a single and consistent format and given in the same timescale, the Terrestrial Time (TT), and reference system, the International Celestial Reference System (ICRS), including necessary changes and corrections. Methods. New CCD observations of Triton and Nereid were made at Lijiang 2.4-m and Yaoan 0.8-m telescopes in 2013–2019, and then reduced based on Gaia-DR2. Furthermore, a catalog called OCNS2019 (Observational Catalog of Neptunian Satellites (2019 version)) was compiled, after recognizing and correcting errors and omissions. Furthermore, in addition to what was considered for the COSS08 catalog for eight main Saturnian satellites, all observed absolute and relative coordinates were converted to the ICRS with corrections for star catalog biases with respect to Gaia-DR2. New debiasing tables for both the modern and old star catalogs, which were previously not provided based on Gaia-DR2, are developed and applied. Treatment of missing positions of comparison bodies in conversions of observed relative coordinates are proposed. Results. OCNS2019 and the new debiasing tables are publicly available online. OCNS2019 includes 24996 observed coordinates of 11 Neptunian satellites obtained over 3741 nights from 1847 to 2019. All observations are given in TT and ICRS. The star catalog biases are removed, which are significant for Nereid and outer satellites. We obtained 880 (5% of total now available) new coordinates for Triton over 41 nights (1% of total observation nights so far), and 790 (14%) for Nereid over 47 nights (10%). The dispersions of these new positions are about 0.″03 for Triton and 0.″06 for Nereid. Conclusions. OCNS2019 should be useful in improving ephemerides for the above-mentioned objects.

Purpose The purpose of this study was to investigate whether a shorter language sample elicited with fewer pictures (i.e., 7) would yield a percent grammatical utterances (PGU) score similar to that computed from a longer language sample elicited with 15 pictures for 3-year-old children. Method Language samples were elicited by asking forty 3-year-old children with varying language skills to talk about pictures in response to prompts. PGU scores were computed for each of two 7-picture sets and for the full set of 15 pictures. Results PGU scores for the two 7-picture sets did not differ significantly from, and were highly correlated with, PGU scores for the full set and with each other. Agreement for making pass–fail decisions between each 7-picture set and the full set and between the two 7-picture sets ranged from 80% to 100%. Conclusion The current study suggests that the PGU measure is robust enough that it can be computed on the basis of 7, at least in 3-year-old children whose language samples were elicited using similar procedures.

Aims: To investigate Montreal Cognitive Assessment (MoCA) test scores in a cohort aged 63–65 years from a general population in relation to the proposed cut-off score of 26 for mild cognitive impairment (MCI) and to explore the impact of education. Methods: MoCA scores were assessed in the Akershus Cardiac Examination 1950 Study, a cross-sectional cohort study of all men and women born in 1950 living in Akershus County, Norway. The participants were aged 63–65 at the time of data collection. Results: MoCA scores were available in 3,413 participants, of which 47% had higher education (>12 years). The mean MoCA score was 25.3 (95% confidence interval [CI] 25.2–25.4), and 49% had a score below the suggested cut-off of 26 points. Those with higher education had significantly higher scores (mean 26.2, 95% CI 26.1–26.3 vs. 24.4, 95% CI 24.3–24.6, p < 0.001). Conclusions: Approximately 50% scored below the cut-off score of 26 points, suggesting that the cut-off score may have been set too high to distinguish normal cognitive function from MCI. Educational level had a significant impact on MoCA scores.

AbstractWe explored whether supported (SJE) or coordinated joint engagement (CJE) between mothers recruited from the community and their 24-month-old children who were slow-to-talk at 18 months old were associated with child language scores at ages 24, 36, and 48 months (n = 197). We further explored whether SJE or CJE modified the concurrent positive associations between maternal responsive behaviours and language scores. Previous research has shown that SJE, maternal expansions, imitations, and responsive questions were associated with better language scores. Our main finding was that SJE but not CJE was consistently positively associated with 24- and 36-month-old expressive and receptive language scores, but not with 48-month-old language scores. SJE modified how expansions and imitations, but not responsive questions, were associated with language scores; the associations were evident in all but the highest levels of SJE. Further research is necessary to test these findings in other samples before clinical recommendations can be made.

The aim of this study was to evaluate the psychometric properties of the Spanish version of the CD-RISC in community dwelling older people, and compare its factorial structure with the original one. We used the following scales: CD-RISC (resilience), PSS (perceived stress), the mental component of the SF-12, GDS (Geriatric Depression) and MOS (social support). It was finally a scale with three dimensions including 17 items. Convergent validity was performed to test whether the means of the variables used are significantly associated with resilience and global scores of Spanish version of CD-RISC scale were directly correlated with the scores of MOS and mental component of SF-12, and inversely related with the scores of PSS and GDS scales. In conclusion the Spanish CD-RISC scale includes 17 items divided into three dimensions, shows acceptable psychometric properties and correlates with social support, perceived stress, depression and mental component of quality of life.

AbstractModern tasks of high precision astrometry demand optical coordinate systems including more faint stars than are available now in current conventional systems (Hipparcos). For this purpose it is suggested to use old photographic observations accumulated in the Pulkovo Observatory. Extensive observational data have been obtained at Pulkovo Observatory during the last century in the framework of several programs, e.g. Pulkovo Galaxy plan, etc. Observations have been made with the Normal Astrograph from 1894 to the present. The data are investigated with the aim of extending the Hipparcos catalog to stars fainter than 11th magnitude. All available observations are taken into account. A description of the material considered is given. The distribution of the selected plates over the celestial sphere is shown as well. Coordinates of faint stars in the Hipparcos system are calculated for selected areas. The accuracy of computed star coordinates is analyzed. Results of the investigation are presented.

The genus Solenysa Simon, 1894 belongs to Linyphiidae Blackwall, 1859, which is a species-rich group, including 608 genera and 4,571 species (World Spider Catalog 2018). Solenysa currently includes 14 species from China, Japan and the Korean Peninsula (Simon 1894; Namkung 1986; Li & Song 1992; Gao, Zhu & Sha 1993; Tu, Ono & Li 2007; Ono 2011; Tu & Hormiga 2011; Wang, Ono & Tu 2015). The linyphiid phylogeny based on molecular data shows that Solenysa species forms one of the seven main clades within Linyphiidae (Wang et al. 2015). According to the phylogenetic analysis based on morphological data, Tu and Hormiga (2011) divided the genus Solenysa into four species groups, each having a unique genital type comprised by series genital characters. As an old branch with a long evolutionary history, Solenysa spiders have accumulated a long list of synapomorphies (Tu & Hormiga 2011), not only having a unique somatic appearance, but also specific genitalic characters that distinguish them from all other linyphiids.

The GS grades of SAB were significantly higher in the shoulders with pm-EORA than in the shoulders with PMR. The GS and PD scores of SAB and the PD scores of SDB were significantly higher in pm-EORA than in PMR cases. The sums of GS and/or PD scores for the three bursae were significantly higher in pm-EORA than in patients with PMR. The sums of GS and PD scores for SAB were significantly higher in pm-EORA than in PMR cases. Moderate to severe proliferative synovitis of the shoulder bursae, especially in SAB, is a key feature for discriminating pm-EORA from PMR.

The metallicity-sensitive (U – G) colors from the new homogeneous catalog of photographic RGU data in seven high-latitude fields have been used to determine the larger-scale metallicity distributions of the Galactic population components. For the thick disk, preliminary analysis based on our best structural models provides a mean metallicity 〈[M/H]〉 = −0.6 ± 0.3dex and a marginal vertical metallicity gradient ≈ −0.1dex/kpc. The observed color distributions are further consistent with the (old) thin disk having mean abundance 〈[M/H]〉 = −0.3 ± 0.2dex and abundance gradient ∂[M/H]/∂z = −0.6dex/kpc.

Continues magnetic measurements at the IKIR FEB RAS obser-vatories Magadan (MGD), Paratunka (PET), Yuzhno-Sakhalinsk (YSS), Cape Schmidt (CPS) and Khabarovsk (KHB) and CSIR-NGRI observatories Hyder-abad (HYB) and Choutuppal (CPL) have been started almost since their formation. A significant part of the results obtained is presented in the WDC and INTERMAGNET databases. However, a large amount of raw data remains un-processed and unavailable for using by scientific community. In the past few years, institutes has been making efforts to process and reprocess old magnetic data. Digital images of analog magnetograms of the Observatory Paratunka since 1967 were obtained and the possibility of their use for calculation hourly and minute values of magnetic field elements was evaluated. Old digital data that was available during the conversion from analog to digital magnetometers is processed. The main problem of processing or re-processing archived data is the lack of information (metadata) about the measurement conditions. First of all, these are the results of absolute observations, which are necessary to obtain the values of the elements of the total field vector. In this paper, some technologies are proposed that allow to use the data obtained during processing of analog magnetograms to adjust the digital magnetometers records. A signif-icant problem is the lack or inaccuracy of information about the temperature conditions in the variation pavilion, about magnetometers or support equipment maintenance or about works in and near the pavilions. As we accumulate the experience during the processing of old magnetic data, a “catalog” of noise and its typical images is formed. This makes it more reliable and efficient to identify and remove this noise from records.

Objective: Subjective health is a complex indicator predicting longevity independent of objective health. Few studies examine genetic and environmental mechanisms underlying different facets of subjective health across the life course. Method: Three subjective health measures were examined in 12,900 twins ( Mage = 63.38, range = 25-102) from nine studies in the Interplay of Genes and Environment across Multiple Studies Consortium: self-rated health (SRH), health compared with others (COMP), and health interfering with activities (ACT). Results: Analyses indicated age and sex differences in mean scores depending on the measure. SRH and ACT showed significant linear and non-linear moderation by age for individual differences in both genetic and environmental variance. Significant sex differences in components of variance were found for SRH and ACT, but not COMP. Discussion: Subjective health appears to be dependent on frame of reference and reflect different aspects of health. Results suggest different genetic and environmental mechanisms underlie each facet.

AbstractAbout 40% of potential OH / IR stars, color selected from the IRAS Point Source Catalog, have no 1612 MHz masers. While these objects are rarely carbon rich, they are usually associated with circumstellar shells. The natural explanation for these “OH / IR star color mimics” is that they are systems with a degenerate companion collecting an accretion disk from a red giant wind. This provides them with an extra source of UV for dissociating their molecules. The persistent absence of the usual complement of masers from an O-rich shell is then a pointer to the presence of a degenerate companion. These occur in association with ~45% of old giant stars.

SynopsisBehavioural/emotional problems were assessed at least nine years after surgical correction for congenital heart disease (ConHD) in childhood. Parents of 144 10–15-year-old ConHD-children completed the Child Behavior Checklist (CBCL) and 179, 11–17-year-old, ConHD-adolescents completed the Youth Self-Report (YSR). On the CBCL and YSR ConHD-children and adolescents obtained significantly higher problem scores than same-aged peers from normative reference groups. No significant differences were found between problem scores for different cardiac diagnostic groups. A negative correlation was found between CBCL total problem scores and IQ-scores of ConHD-children; for YSR total problem scores no such relationship was found.

The study investigated single-word spelling performance of 33 English- and 38 Greek-speaking monolingual children, and 46 English- and Greek-speaking bilingual children (age range from 6;7 to 10;1 years). The bilingual children were divided into two groups on the basis of their single-word reading and spelling performance in Greek. In line with predictions, we found that scores on an assessment of phonological awareness were a significant predictor of spelling in English for the bilingual children with stronger Greek literacy skill. Phonological awareness scores were also a strong predictor of spelling in Greek in the monolingual Greek-speaking children. For the bilingual children with weaker Greek literacy ability, spelling in English was predicted by performance in a test of visual memory. This was more in line with results for the monolingual English-speaking children, for whom spelling performance was predicted by visual memory and phonological awareness scores. Qualitative analysis of misspellings revealed that phonologically appropriate errors were significantly greater in the strong Greek literacy ability bilingual group than the weaker Greek literacy ability bilingual group. Stimulus analyses using regression techniques are also reported. The results are interpreted to suggest that in biliterates literacy processes are transferred from one language to the other (Mumtaz & Humphreys, 2002).

Background Life expectancy is increasing in most high-income countries, but gains in life years are maximized if spent in good health and if cognitive abilities are maintained until old age. Age-related decline of cognitive abilities does nevertheless occur, but the pace of decline is decisive. This was the starting point for our study that aims to examine cohort effects of cognitive aging in women and men in Germany, Spain and Sweden by analyzing changes from 2004 to 2013 by estimating cohort effects within age groups starting from the age of 50 years. Methods A cohort study was conducted that was based on data of the surveys 2004 (N = 6,081) and 2013 (N = 8,650) from the Survey of Health, Ageing and Retirement in Europe (SHARE). The analyses were based on data of female and male respondents aged 50 years and older. Age-specific means of verbal fluency and delayed recall from the German, Spanish and Swedish samples were the cognitive domains considered in the study. Results In both domains of cognitive ability the achievements in the later surveys were higher than in the earlier ones. This was found in all countries, abut achievement levels increased markedly in the German and the Spanish samples, while the scores of the Swedish samples were not significantly different. While the highest scores were found for Sweden, Germany ranked in the middle and the lowest scores were found in the Spanish samples. Over time, the scores of the German samples approached those of Sweden. Conclusions From the first to the second survey, improvements of older adults’ cognitive abilities were found for all countries considered. This may indicate improvements of the underlying educational systems, but also increasingly stimulating general living conditions.

A total of 101 mothers from two socio-cultural groups (55 French-speaking from Montreal and 46 English-speaking from Chicago) described their 2-or 3-year-old children using the Attachment Q-sort. The Q-sort descriptions from the two sites were compared at the level of criterion scores, at the level of derived scores for nine empirical scales, and at the level of individual Q-sort items. These analyses indicated only chance level differences between groups for analyses individual items. However, for the derived scales and for criterion scores, significant multivariate effects across samples were obtained. Additional analyses, covarying maternal age, education level, and social desirability response bias scores, indicated that only the criterion score for Attachment Security differed across the two socio-cultural groups. Subsequent correlational analyses relating empirical scale scores to the criterion scores for both samples yielded similar results. Only 3 of 27 separate pairs of correlations differed significantly across the two samples. The results suggest that the Attachment Q-sort is useful for evaluating differences among young children with respect to attachment security and related constructs in both sociocultural groups. However, the results also indicate that the scores derived from maternal Q-sort descriptions may be associated with demographic characteristics and culturally specific response biases that should be evaluated and controlled before interpreting the Q-sort scores with reference to universal, or species-specific, concepts of attachment security.

Introduction: Progress testing (PT) reflects students’ knowledge development and is a valuable indicator for curriculum evaluation. Since 2009, Faculty of Medicine Syarif Hidayatullah State Islamic University Jakarta (FMSH) has been conducting PT every year as a formative assessment. In 2012, curriculum reform was addressed to revise the 2005 curriculum; until then PT and curriculum evaluation were not conducted concurrently. This study aims to evaluate PT and assess whether there is a relationship between PT performance and final scores in modules, as part of curriculum evaluation.Method: It reviews PT for two cohorts: 571 students in 2015 and 562 students in 2016. 120 systembased topics were addressed in the PT. In this study the final scores for the old (2015) and new (2016) curriculum neuropsychiatry modules are reviewed, since their scores were lower than for other modules. Comparisons were made using ANOVA. Pearson correlations were calculated to examine the relationship between PT and final module scores.Results: This study revealed that PT scores between each grade (p < 0.001) from 2015 to 2016 improved significantly (54.49 ± 7.43 and 55.07 ± 8.32; p < 0.001). The mean of the final score of the new neuropsychiatry module was 69.36 ± 3.78 while the old one was 70.92 ± 3.99. Furthermore, Pearson correlation showed a weak correlation between final scores for the neuropsychiatry module and PT scores in 2015 (ρ = 0.191, p = 0.011).Discussion: PT scores increased significantly. Despite the final score of the new neuropsychiatry module being lower than the old one, there was heterogeneity in scores within the old neuropsychiatry module. The small number of neuropsychiatry items in the PT explains why the correlation between PT and final scores was weak. The weak correlation between final scores for the neuropsychiatry module and the PT scores in 2015; PT and final module scores seem reliable as indicators of curriculum evaluation. Further study is needed to analyze more cohort PT scores and modules.International Journal of Human and Health Sciences Vol. 05 No. 01 January’21 Page: 62-68

Abstract The objective was to determine effects of interlocking rubber floor matting in slatted indoor cattle feeding facilities on cattle locomotion. In experiment 1, Fall-born Angus × Simmental steers (N = 206; BW = 228 ± 34 kg) were blocked by weight and assigned to 32 pens. Pens were randomly assigned to 1 of 4 treatments: new Max Grip Animat matting (MG), new Animat Pebble matting (PEB), old Animat Pebble matting (OLD), and no matting/concrete slating (CONC). Steers were fed a common diet for 209 d with an average stocking density of 3.70 m2 per steer. Locomotion scores were assigned by two trained staff using a 0–3 scale of the Step-Up® Locomotion Scoring System (Zinpro, Eden Prairie, MN) throughout both experiments. There was no treatment by day interaction (P = 0.88) observed. Treatment affected (P < 0.01) locomotion scores with CONC being the greatest and MG, PEB, and OLD being lesser and not different from each other. Locomotion scores also increased (P < 0.01) over time. In experiment 2, Fall-born Angus × Simmental steers (n = 189; BW = 352 ± 43 kg) were blocked by weight and assigned to 21 pens. Pens were randomly assigned to 1 of 3 treatments: new Animat Pebble matting (PEB2), old Animat Pebble matting (OLD2), or no matting/concrete slating (CONC2). Steers were fed a common diet for 152 d with an average stocking density of 2.64 m2 per steer. There was no treatment by day interaction (P = 0.42) observed. However, both treatment and day affected (P ≤ 0.02) locomotion scores. Steers on CONC2 had the greatest locomotion score, while PEB2 and OLD2 were not different from each other. Locomotion scores were the greatest on d 152. Overall, results suggest new and old rubber floor matting improved locomotion scores of feedlot steers in slatted indoor cattle feeding facilities.

The purpose of this study was to examine the correlation between body surface potential distribution and the extent of abnormally contracting segments (ACS) of the left ventricle in patients with old myocardial infarction (MI). Body surface potential distribution was quantitatively analyzed using principal component analysis. The first six principal components were extracted from data set obtained from both 25 normal subjects and 100 patients. The z scores (principal component weights) were calculated in a time domain at every 4 or 8 ms in another 81 patients with previous MI. In anterior MI, the second z scores on T wave and the fourth z scores on QRS complex were significantly lower in the presence than in the absence of ACS at the lateral wall. In inferior MI, the first z scores on QRS complex, the second on T wave, and the third on both Q and T represented significant differences between the presence and the absence of ACS at the posterior wall. Minute differences in the extent of ACS were sensitively and noninvasively detected on z scores of principal components.

Objective This study was designed to compare nasalance scores obtained with the old Nasometer 6200 and the new Nasometer II 6400, and to evaluate test-retest reliability of nasalance scores on each machine. Design Nasalance scores were obtained for 60 subjects reading each of two stimuli. Each subject read each stimulus two times on one machine; the headgear was removed and replaced and each stimulus was read a third time. The same procedure was then repeated with the second machine. Within machines, nasalance scores were compared for repeated stimuli with and without headgear change. The first reading of each stimulus with each machine was used to compare nasalance scores across machines. Participants The subjects were 60 adults with normal speech ranging in age from 19 to 59 years. Main Outcome Measures The main outcome measures were the 12 nasalance scores obtained for each of 60 subjects. Results For both passages, there was a significant difference in nasalance scores between the old Nasometer and the Nasometer II; however, the actual variability that could be attributed to a difference between machines was small. Most of the variability between machines could be explained as within-subject performance variability and variability associated with headgear change. There was no significant difference in repeated scores within machines with or without headgear change. Conclusions For clinical purposes, care should be exercised when comparing nasalance scores between the old Nasometer and the Nasometer II.

Introduction Frailty is a state of being vulnerable to adverse health outcomes such as falls, delirium, and disability in older people. Identifying frailty is important in a low-income setting to prevent it from progressing, reducing healthcare costs, increasing the chances of reversibility, and implementing effective interventions. The factors affecting frailty in older people living in old age homes could differ from those living in the community. This study was conducted to identify the factors associated with frailty in older people residing in old age homes and communities in Kathmandu Valley, Nepal. Methods This is a cross-sectional study conducted from April to June 2019 in three districts of Kathmandu Valley, Nepal. Data were collected from 193 older people residing in old age homes and 501 residing in communities aged 60 and above using convenience sampling. Frailty was measured using the Groningen Frailty Indicator. Data were collected via face-to-face interviews. Multiple linear regression analyses were used to examine the association between independent variables and frailty. Results Frailty was more prevalent among older people in old age homes (71.5%) compared to those in the community (56.3%). Older people who were satisfied with their living environment had lower frailty scores in both old age homes (β = -0.20, p<0.01) and the community (β = -0.15, p<0.001). Those who had self-rated unhealthy lifestyle had higher frailty scores in both old age homes (β = 0.45, p<0.001) and the community (β = 0.25, p<0.001). In the community, those over 80 years of age had higher frailty scores (β = 0.15, p<0.01) and those with higher education had lower scores (β = -0.13, p<0.05). Conclusion The living environment and lifestyle are key modifiable risk factors of frailty, both in old age homes and the community. The findings suggest a need for lifestyle modification and reforms in building standards, especially in old age homes, to promote age-friendly communities.

Suicide is one of the leading causes of death worldwide, mortality from suicide being approximately 2%. Attempted suicide appears to be a major risk factor for suicide completion. Anger, aggression and impulsivity are personality traits associated with suicide attempt. We analysed anger, impulsivity and temperament/character scales as predictors of aggression and self-aggression in suicide attempters and compared this to anger- and aggression-related traits between impulsive and premeditated suicide attempts as well as between violent and non-violent suicide methods.The State-Trait Anger Expression Inventory (STAXI), the Questionnaire for Measuring Factors of Aggression (FAF), and the Temperament and Character Inventory (TCI) were assessed.Higher aggression scores, as measured by FAF, were predicted by being male, meeting criteria for borderline personality disorder and having higher angry temperament scores as assessed by STAXI. TCI dimensions associated with self-aggression were high harm avoidance, high impulsivity and low selfdirectedness.State anger, inwardly directed anger and inhibition of aggression were also predictors of self-aggression.In conclusion, impulsivity and harm avoidance have emerged as temperament dimensions independently associated with self-aggressive tendencies in personality. Such interactions could explain the correlation between temperament and suicidality but further research is needed. Anger and selfdirectedness appear to have some effects on suicide attempt.

English receptive vocabulary scores from 797 monolingual and 808 bilingual participants between the ages of 17 and 89 years old were aggregated from 20 studies to compare standard scores across language groups. The distribution of scores was unimodal for both groups but the mean score was significantly different, with monolinguals obtaining higher standard scores than bilinguals. Consistent with previous research, older adults had higher vocabulary scores than younger adults. The results are discussed in terms of the implications for theoretical conceptions of linguistic processing and clinical diagnosis in bilingual populations.

Full textAbstract:
The ability of young and middle-aged adults to solve series problems was assessed with problems connected by either marked or unmarked adjectives. Half the participants given each type of problem were instructed to use imagery. Information needed to answer memory and inference questions was explicitly provided, but additional information from semantic memory was needed to answer integration questions. Overall, there was no difference between age groups on the memory measure, but scores on both integration and inference measures were significantly lower for the middle-aged group, a result suggesting a deficit in the ability to manipulate items in working memory. Imagery instructions facilitated scores of both age groups equally for the integration measure, but affected neither memory nor inference scores, indicating that middle-aged adults are able to use imagery as a control process as effectively as younger adults, and also that imagery is most useful for developing an array. Finally, the only effect of adjective type was that marked adjectives significantly improved inference scores of middle-aged adults.

Astrometry is the oldest of the astronomical endeavors. Indeed, we still have the observing journals of Galileo, the journals of Flamsteed, and those of most of the other old transit-circle astronomers. We have most of the early photographic plates taken for the astrographic catalog project, and almost all the parallax plates. However, as technology progressed, we have become somewhat less precise in recording what we did. It is for this reason that this joint meeting was called: to impress on the modern astronomer that, in general, he only extracts a fraction of the information from his observations, and that these observational data may, in the future, provide an invaluable source needed for the progress of the science.

AbstractThe TOCAMM (TOrino CAgliari Measuring Machine) project undertaken jointly between Torino and Cagliari Astronomical Observatories aimed to convert the old measuring machine ASCORECORD into an automatic and impersonal one. This program is intended to contribute to the link of the HIPPARCOS Catalogue to the ICRS through the determination of precise position of optical counterparts of 80 extragalactic radiosources taken from the IERS list and to investigate the astrometric accuracy of the Guide Star Catalog (version 1 and 2). The calibration test phase, carried out first at the Astronomical Observatory of Torino and after at Cagliari Observatory, where the machine has been now installed, indicate that the available positional accuracy is about 0.5 microns in both x and y coordinates.

Context. In Gaia DR2, an unprecedented high level of precision has been reached at sub-milliarcsecond for astrometry and millimagnitudes for photometry. Using cluster members identified with the astrometry and photometry in Gaia DR2, we can obtain a reliable determination of cluster properties. However, because of the shortcomings of Gaia spectroscopic observations in dealing with densely crowded cluster regions, the RVs and metallicity values for cluster member stars from Gaia DR2 are still lacking. It is necessary to combine the Gaia data with the data from large spectroscopic surveys, such as LAMOST, APOGEE, GALAH, and Gaia-ESO. Aims. In this study our aim is to improve the cluster properties by combining the LAMOST spectra. In particular, we provide the list of cluster members with spectroscopic parameters as an add-value catalog in LAMOST DR5, which can be used to perform a detailed study for a better understanding of the stellar properties, by using their spectra and fundamental properties from the host cluster. Methods. We cross-matched the spectroscopic catalog in LAMOST DR5 with the identified cluster members in Cantat-Gaudin et al. (2018, A&A, 618, A93). We then used members with spectroscopic parameters to derive statistical properties of open clusters. Results. We obtained a list of 8811 members with spectroscopic parameters and a catalog of 295 cluster properties. The provided cluster properties include astrometric parameters, spectroscopic parameters, derived kinematic and orbital parameters, and isochrone fitting results. In addition, we study the radial and vertical metallicity gradient and age-metallicity relation with the compiled open clusters as tracers, finding slopes of −0.053 ± 0.004 dex kpc−1, −0.252 ± 0.039 dex kpc−1, and 0.022 ± 0.008 dex Gyr−1, respectively. The slopes of the metallicity distribution relation for young clusters (0.1 Gyr < Age < 2 Gyr) and the age-metallicity relation for clusters within 6 Gyr are both consistent with the literature results. In order to fully study the chemical evolution history in the disk, more spectroscopic observations for old and distant open clusters are needed for further investigation.

Abstract Background Direct Observation of Procedural Skills (DOPS) is an established competence assessment tool in endoscopy. In July 2016, the DOPS scoring format changed from a performance-based scale to a supervision-based scale. We aimed to evaluate the impact of changes to the DOPS scale format on the distribution of scores in novice trainees and on competence assessment. Methods We performed a prospective, multicenter (n = 276), observational study of formative DOPS assessments in endoscopy trainees with ≤ 100 lifetime procedures. DOPS were submitted in the 6-months before July 2016 (old scale) and after (new scale) for gastroscopy (n = 2998), sigmoidoscopy (n = 1310), colonoscopy (n = 3280), and polypectomy (n = 631). Scores for old and new DOPS were aligned to a 4-point scale and compared. Results 8219 DOPS (43 % new and 57 % old) submitted for 1300 trainees were analyzed. Compared with old DOPS, the use of the new DOPS was associated with greater utilization of the lowest score (2.4 % vs. 0.9 %; P < 0.001), broader range of scores, and a reduction in competent scores (60.8 % vs. 86.9 %; P < 0.001). The reduction in competent scores was evident on subgroup analysis across all procedure types (P < 0.001) and for each quartile of endoscopy experience. The new DOPS was superior in characterizing the endoscopy learning curve by demonstrating progression of competent scores across quartiles of procedural experience. Conclusions Endoscopy assessors applied a greater range of scores using the new DOPS scale based on degree of supervision in two cohorts of trainees matched for experience. Our study provides construct validity evidence in support of the new scale format.

Correlates were as follows: Mini Nutritional Assessment (MNA), PA (Baecke questionnaire modied for older adults), Quality of life (QoL SF- 12), Geriatrics Depression Scale (GDS), Satisfaction and Social Support Scale, and Socioeconomic status (SES). All instruments were applied in a face to face interview. An independent t-test identied signicantly higher scores in young-old adults (≤ 69 years) for CF (p < 0.001), PA (p = 0.046) and SES (p = 0.007), compared to old-old adults (≥ 70 years). e results of multiple linear regression analysis indicated that the most signicant CF correlates were SES (β = 0.45; p < 0.001), age (β = -0.12; p < 0.001), SS (β = 0.12; p = 0.001), GDS (β = -0.11; p = 0.003) and QoL (β = 0.08; p = 0.017). The overall regression model explained 36% of the total variance in the COGTEL. The oldest and the more depressed adults obtained lower scores for FC. The present study suggests that, between the correlates studied, SES was the strongest predictor in the explanation of CF in older adults.

e21524 Background: AYAs experience many distinct periods of developmental transition within this life stage. AYA survivors of childhood cancer are at risk for chronic physical and psychosocial health conditions due to treatment-related exposures. Few studies have evaluated HRQL differences that may exist among developmental subgroups of AYA cancer survivors. This study examined HRQL differences across AYA developmental subgroups (early teens 12-14 years; late teens 15-17; emerging adults 18-24; young adults 25-39) of long term childhood cancer survivors. Methods: Cancer survivors ages 12-39 years who were seen in a long term follow up clinic at time of survey completion (as part of larger HRQL study) and completed therapy ≥2 years ago were included. HRQL was assessed using PedsQL (< 18) and FACT-G (> 18) measures. Demographic and treatment data were obtained from EMR. Analyses compared HRQL measure scores among AYA age subgroups and investigated predictors of HRQL outcomes. Results: A total of 155 patients were included in analysis. Mean age at survey completion was 17.9 [range 12-33] years. PedsQL school functioning was significantly lower for 15-17 year-old compared to 12-14 year-old survivors (M = 77.60, p = 0.01). There were no differences between 18-24 and 25-39 year-old survivors on the FACT-G. PedsQL school functioning was significantly lower for survivors (< 18) compared to normative data (p = 0.004). FACT-G scores for survivors were significantly higher compared to population norms in all domains (p≤0.001) except emotional well-being. Regression CART analysis indicated survivors who were ≤15 years-old and had not relapsed and survivors who were > 15 years old and had ≥2 late effects had lower PedsQL scores. Survivors who were ≥21 years-old had lower FACT-G scores compared to < 21 years. Survivors who were < 21 years-old, > 7 years-old at diagnosis, and > 6 years from end of treatment had lower FACT-G scores. Conclusions: Adolescent survivors may be at risk for school problems years after cancer treatment. Young adult survivors may be at greater risk of poor HRQL. This study highlights potential developmental differences in HRQL predictors and outcomes in long term AYA cancer survivors.

Background : In Indonesia, particularly among Bataknees men in Medan, tuak has been known as a staple, enjoyed by mostly men to strengthen their brotherhood. Concurrent Anxiety Disorders and Alcohol Use Disorders (AUD) are relatively common and closely related to the presentation of complex clinical symptoms that warrant an appropriate diagnosis and treatment. Method : Sixty tuak drinkers from 4 districts of Medan were recruited by using a cluster sampling method. Participants aged 25-55 years old with inclusion criteria were Batak men who drank Tuak, minimum education by completing junior high school and history of drinking tuak took less than 12 months, and AUDIT cutoff value less than or equal to 7. This study's exclusion criteria were no history of psychiatric and general health disorders in the subject. Result : The results of this study found a significant relationship between the HADS-A score and the AUDIT total score. Also found a significant relationship between the drinking frequency score, the drinking quantity score, the frequency score of heavy drinking, and the HADS-A score. Conclusion : The results of this study are essential evidence to promote mental health in the future, especially in the city of Medan.

Abstract We compared verbal list learning, verbal memory, animal fluency, and letter fluency in 1407 education-matched participants from two community-based, intergenerational studies of cognitive aging and dementia. WHICAP participants are sampled from Medicare-eligible people aged 65+ and the Offspring cohort includes their middle-aged children. WHICAP participants (n=1218) were 72.1±6.5 years old and Offspring participants (n=189) were 53.7±8.4 years old at baseline. WHICAP participants had lower scores on most cognitive measures than Offspring participants; however, these differences were not uniform across race/ethnicity. Compared to non-Hispanic Whites, non-Hispanic Blacks in WHICAP had disproportionately lower scores on letter fluency compared to their offspring. On delayed verbal memory, non-Hispanic White and Hispanic offspring obtained higher scores than the parent generation – but among Blacks, memory scores were relatively low regardless of cohort. Racial disparities in cognition are apparent in both mid- and late-life and may be amplified in older age, particularly in Blacks.

Full textAbstract:
The article is devoted to Cyrillic handwritten books of the XIII–XIX centuries, created in the Romanian principalities, and stored today in the manuscript collections of the Russian State Library. The uniqueness of the writing system, functioning in the principalities (Wallachia, Moldavia, Transylvania) since their political formation, is that it was a Cyrillic script based on the old Slavic language with a predominant Roman-speaking population. In course of the writing system’ development in the principalities, there was a transition from the Slavic font to the Latin one; the intermediate result of this transition was the creation of monuments written in Romanian language with Cyrillic script. The main stages of this process are considered by reference to the specific examples of unique handwritten books and their fragments that have become objects for collecting by scientists, antiquaries, and Old Believers, whose book collections have formed the basis of the handwritten collections of the Russian State Library. They are the oldest Cyrillic manuscripts and their fragments dated to the XII–XIV centuries, found on the territory of Romania, Slavic manuscripts, produced mainly in monasteries of principalities in the XV–XVII centuries, translations of individual words into the Romanian language in the rewritten Slavic texts in the XVI century; the glosses and comments in Romanian on the margins of Slavic manuscripts in the XVI–XVIII centuries; numerous notes in the Romanian language in the manuscripts of the XVI–XVIII centuries, made by owners and readers; translations of literary monuments, including bilingual (Slavic–Romanian) and trilingual (Slavic–Latin–Romanian) versions in the XVI–XVIII centuries; Romanian–Slavic and Slavic–Romanian dictionaries in the XVII–XVIII centuries; letters and their copies in the Romanian language (sureties) in the XVI–XIX centuries. The article is an intermediate outcome of studying and describing Cyrillic Romanian handwritten books in the collections of the Russian State Library, which will result in the publication of a hard–copy catalog.

AbstractPatient expectations and demographics are vital factors in determining patient satisfaction and outcomes from total knee arthroplasty (TKA). This study was a retrospective chart review that analyzed data from TKA patients to determine the impact of age on patient-reported outcomes measures following TKA. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Oxford knee scores were collected as primary outcome measures from 356 consecutive patients who underwent TKA. Oxford knee scores were further divided into pain and function subscores. Patients were age categorized as <50, 50 to 59, 60 to 69, 70 to 79, and >79. Preoperative scores were compared among age categories including age category, gender, body mass index (BMI), and length of stay (LOS) in the model as fixed effects. Scores collected postoperatively (∼10, 30, 90, and 180 days postoperation) were analyzed as repeated measures including age category, day and their interaction, gender, BMI, LOS, and preoperative score in the model. Preoperative OXFORD scores significantly differed among age categories (p < 0.05) and were numerically higher for the older (≥60 years old) compared with younger patients (<60 years old). After adjusting for preoperative scores, postoperative WOMAC and overall, pain, and function OXFORD scores significantly differed among the age groups (p < 0.05), with patients younger than 60 years reporting the worst scores in the postoperative time period. Older patients reported better preoperative overall, pain, and function scores and greater post-TKA outcomes than younger patients. A better understanding of factors that influence patient-reported outcomes can help providers to better manage patient expectations.

Abstract Objective The necessity for pre-injury baseline computerized neurocognitive assessments versus comparing post-concussion outcomes to manufacturer-provided normative data is unclear. Manufacturer-provided norms may not be equivalent to institution-specific norms, which poses risks for misclassifying the presence of impairment when comparing individual post-concussion performance to manufacturer-provided norms. The objective of this cohort study was to compare institutionally derived normative data to manufacturer-provided normative values provided by ImPACT® Applications, Incorporated. Method National Collegiate Athletic Association Division 1 university student athletes (n = 952; aged 19.2 ± 1.4 years, 42.5% female) from one university participated in this study by completing pre-injury baseline Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) assessments. Participants were separated into 4 groups based on ImPACT’s age and gender norms: males <18 years old (n = 186), females <18 years old (n = 165), males >19 years old (n = 361) or females >19 years old (n = 240). Comparisons were made between manufacturer-provided norms and institutionally derived normative data for each of ImPACT’s clinical composite scores: Verbal (VEM) and Visual (VIM) Memory, Visual Motor Speed (VMS), and Reaction Time (RT). Outcome scores were compared for all groups using a Chi-squared goodness of fit analysis. Results Institutionally derived normative data indicated above average performance for VEM, VIM, and VMS, and slightly below average performance for RT compared to the manufacturer-provided data (χ2 ≥ 20.867; p < 0.001). Conclusions Differences between manufacturer- and institution-based normative value distributions were observed. This has implications for an increased risk of misclassifying impairment following a concussion in lieu of comparison to baseline assessment and therefore supports the need to utilize baseline testing when feasible, or otherwise compare to institutionally derived norms rather than manufacturer-provided norms.

AbstractThe SUPERBLINK survey catalogs all stars brighter than R = 19 mag and with proper motions larger than 40 mas yr−1, down to a declination of −33○. The catalog inevitably includes a significant fraction of the presumed low-mass members of several nearby young moving groups (Beta Pic, AB Dor, Tuc-Hor, Argus), or low-mass escapees from the Hyades and Pleiades clusters. We discuss opportunities and challenges in identifying the missing M dwarf members of these moving groups. While rounding up the majority of the potential M dwarf members of these groups, such samples are significantly affected by co-moving field stars, both young and old, due to the heavy clumping of the local field population in velocity space.

AbstractThe mid-infrared provides a unique view of galaxy stellar populations, sensitive to both the integrated light of old, low-mass stars and to individual dusty mass-losing stars. We present results from an extended Spitzer/IRAC survey of M31 with total lengths of 6.6 and 4.4 degrees along the major and minor axes, respectively. The integrated surface brightness profile proves to be surprisingly difficult to trace in the outskirts of the galaxy, but we can also investigate the disk/halo transition via a star count profile, with careful correction for foreground and background contamination. Our point-source catalog allows us to report on mid-infrared properties of individual objects in the outskirts of M31, via cross-correlation with PAndAS, WISE, and other catalogs.

In-patients suffering from major depressive disorder (endogenous subtype) were randomly allocated to treatment by either traditional ECT with constant-voltage modified sine-wave stimuli (n = 17) or modern, constant-current brief-pulse ECT (n = 14). All treatments were bilateral and monitored by simultaneous recording by EEG. The severity of depressive illness was assessed the day before treatment, after three treatments, and seven days after the last treatment. The improvement and final depression rating scores, the likelihood of recovery, and the average number of treatments received were virtually identical in the two groups. We concluded that the policy of bilateral suprathreshold modern ECT monitored by EEG is as efficacious as traditional ECT.

Full textAbstract:
The aim of the study was to determine the effects of a multi-component community-based health promotion intervention on body mass index (BMI) z-scores and waist circumference (WC) in three- to eight-year-old children. A quasi-experimental design was adopted to evaluate the effects of the SoL intervention involving three intervention and three control communities. The 19-month intervention was based on the supersetting approach and was designed to promote healthier eating and physical activity among children and their families. BMI z-scores and WC were measured at baseline and follow-up. At baseline, 238 (54%) and 214 (51%) of all eligible children were measured from intervention and control, respectively. The change over time in the BMI z-scores of children from the intervention group was significantly different from that of the control group (p = 0.001). BMI z-scores increased over time in the intervention group in contrast to the control group, whose BMI z-scores decreased (difference in change between groups 0.19 z-scores 95% CI 0.08, 0.30). No significant differences were observed for WC. The results showed no favourable effects of the intervention of Project SoL on BMI z-scores and WC in children. Further studies based on a larger sample size and a longer intervention duration are needed.
