Diving into a pool or volcano? Examining the influence of sentence context and task demands on sentence reading in younger and older adults

Cognitive ageing is often associated with slower lexical processing, which might influence both language production and comprehension. Words are typically used in context, which can further influence word processing and potential age differences. However, it remains unclear how older adults are affected by context during reading. Older adults are reported to have in-tact semantic knowledge, which could potentially help them to process words predicted by semantic information in the preceding context. However, potential difficulties with semantic control might mean older adults have greater difficulty suppressing interfering information from mismatching contexts. In this study we examined the influence of contexts that either predicted a specific target word (“matched”, e.g., “The man watched the lava erupt from the volcano”) or predicted another word than the target (“mismatched”, e.g., “The swimmer dived into the volcano”) as compared to neutral contexts (e.g., “They went to see the volcano”). We also examined the potential role of task demands by asking participants to either just read the sentences for comprehension or to answer questions. Forty younger adults (18–35 years old) and forty older adults (65–80 years old) completed a self-paced reading task in which we measured reading times for the target words. Older adults showed slower reading times overall. Matched sentence contexts facilitated reading times in both age groups. Surprisingly, mismatched sentence contexts did not hinder reading times in either age group. Furthermore, reading times were not influenced by task demands. Together, this shows the importance of studying language in context. While interference from mismatching sentence contexts might have not been substantial enough to delay reading, reading was faster when processing expected words. This suggests older adults can indeed benefit from semantic knowledge to facilitate word processing during comprehension. This occurred even when no additional task was presented and people were purely reading for comprehension.
Older adults’ emotion recognition: No auditory-visual benefit for less clear expressions

The ability to recognise emotion from faces or voices appears to decline with advancing age. However, some studies have shown that emotion recognition of auditory-visual (AV) expressions is largely unaffected by age, i.e., older adults get a larger benefit from AV presentation than younger adults resulting in similar AV recognition levels. An issue with these studies is that they used well-recognised emotional expressions that are unlikely to generalise to real-life settings. To examine if an AV emotion recognition benefit generalizes across well and less well recognised stimuli, we conducted an emotion recognition study using expressions that had clear or unclear emotion information for both modalities, or clear visual, but unclear auditory information. Older (n = 30) and younger (n = 30) participants were tested on stimuli of anger, happiness, sadness, surprise, and disgust (expressed in spoken sentences) in auditory-only (AO), visual-only (VO), or AV format. Participants were required to respond by choosing one of 5 emotion options. Younger adults were more accurate in recognising emotions than older adults except for clear VO expressions. Younger adults showed an AV benefit even when unimodal recognition was poor. No such AV benefit was found for older adults; indeed, AV was worse than VO recognition when AO recognition was poor. Analyses of confusion responses indicated that older adults generated more confusion responses that were common between AO and VO conditions, than younger adults. We propose that older adults’ poorer AV performance may be due to a combination of weak auditory emotion recognition and response uncertainty that resulted in a higher cognitive load.
High baseline body mass index predicts recovery of CD4+ T lymphocytes for HIV/AIDS patients receiving long-term antiviral therapy

The relationship between baseline BMI and CD4+ T cells during follow-up in HIV patients in China requires further evaluation. We conducted a retrospective cohort study based on adult AIDS patients who underwent or received antiretroviral therapy from 2003 to 2019 in Guangxi, China. BMI was divided into categories and compared, and after adjusting for BMI being related to the change in CD4 lymphocyte count, with normal weight as the reference group, the BMI before treatment was positively correlated with the changes in CD4+ T cells at different time periods. Among them, obese patients had significant CD4+ cell gain. In patients with pretreatment CD4+ T lymphocyte counts <200 cells/μL, a higher BMI was associated with an increased likelihood of achieving immunologic reconstitution [≥350 cells/μL: AHR: 1.02(1.01, 1.04), P = 0.004; ≥500 cells/μL: AHR: 1.03 (1.01, 1.05), P = 0.004]. Underweight in HIV patients was a risk factor for poor viral suppression [AHR: 1.24 (1.04, 1.48), P = 0.016]. Our study demonstrated that HIV/AIDS patients receiving ART with higher baseline BMI had better immune reconstitution and that baseline BMI could be an important predictor of immune reconstitution in patients receiving ART. Baseline BMI was not associated with virological failure, but a lower baseline BMI indicated poor viral suppression during follow-up.
A Comparison between Mucoderm® and Connective Tissue Graft for Root Coverage

Statement of the Problem: Subepithelial connective tissue graft (SCTG) is the gold stand-ard treatment for root coverage procedure; however, this technique has limitations such as the need for a donor site and the difficulty of the harvesting procedure. The potential bene-fits of Mucoderm®, a collagen matrix derived from porcine dermis, as an alternative treat-ment for root coverage can be investigated. Purpose: This study aimed to evaluate the efficacy of Mucoderm® for root coverage and compare its results with SCTG. Materials and Method: This double-blind split-mouth randomized clinical trial was con-ducted on seven patients with 12 bilateral gingival recessions (24 recession sites). Coronally advanced flap + Mucoderm® was applied on one side and coronally advanced flap + con-nective tissue graft (CTG) was applied on the contralateral side. We measured the periodon-tal pocket depth (PPD), clinical attachment level (CAL), recession depth (RD), keratinized tissue width (KTW) and gingival thickness (GT) with a surgical stent at baseline (preopera-tively) and at 1, 3 and 6 months postoperatively. The Wilcoxon and Friedman tests were used to analyse the data. Results: The mean percentage of root coverage was 26% in the Mucoderm® group and 60% in the SCTG group at 6 months, compared with baseline. The mean percentage of root coverage was significantly different between the two groups (p Value< 0.05). The results indicated that Mucoderm® did not increase the KTW, while CTG significantly increased the KTW (p Value< 0.05 at 1, 3 and 6 months). Conclusion: The results of this study showed that Mucoderm® might not be an appropriate alternative for the CTG in root coverage procedures.
Large-Eddy Simulation of an Idealized Tropical Cyclone

Advances in computing have allowed presentday numerical weather-prediction models to forecast and/or simulate tropical cyclones (TCs) with high resolution (horizontal grid spacing ~1 km). While these numerical models of TCs can capture many of their important structural features (eyewall, rainbands, etc.), the effects of small-scale [ ~ 0 (100 m)], three-dimensional turbulence must still be parameterized. No objective basis has yet been found for such parameterizations, yet the maximum wind speeds in axisymmetric numerical TC models have been shown to be highly sensitive to the radial turbulent transfer and diffusion at these scales. As there is little observational guidance on the nature of radial turbulent diffusion in a TC, the present study was conceived to indicate the impact of these effects through computation of the small-scale scale turbulence (i.e., a large-eddy simulation, or LES) using a numerical weather prediction model applied to an idealized tropical cyclone. The numerical experiments reported on herein were carried out with the Advanced Research Weather research and forecasting (ARW) model, version 2.2, using six nested grids centered on the TC. As the ARW model is nonhydrostatic, it can and has been used as an LES model,1 and therefore one can expect the numerical solutions to capture turbulent eddies,
Hα Dimmings Associated with the X1.6 Flare and Halo Coronal Mass Ejection on 2001 October 19

As the optical counterpart of coronal dimmings, we present the first direct evidence of Hα dimmings associated with the X1.6 flare, filament eruption, and coronal mass ejection (CME) that occurred on 2001 October 19. As two main Hα flare ribbons parallel to the erupting filament slowly separated, two other ribbons first quickly expanded near the feet of the filament, then their interiors substantially dimmed and became darker than the preflare brightness. This formed two dimming regions with sharp bright edges. The two Hα dimmings were different from the flare nimbus and the Hα darkenings found by Ellison, McKenna, & Reid and Neidig et al., respectively, but similar to the coronal "double dimmings" studied by Sterling & Hudson. The coronal dimmings of the event were also observed in 171 Å images from the Transition Region and Coronal Explorer (TRACE). The 171 Å and Hα dimmings showed very similar evolutions and occurred at the same two sites with opposite magnetic polarities. They formed in the course of the filament eruption, and after the eruption, some 171 Å loops of the postflare arcade developed to connect their inner edges while some loops with footpoints near their outer edges disappeared. Observations from the Solar and Heliospheric Observatory Extreme-ultraviolet Imaging Telescope (SOHO/EIT) showed more extended dimmings associated with the eruption. Only a small portion of EIT dimmings was cospatial with the Hα dimmings, while the major other portion was associated with the disappeared 171 Å loops. These joint observations are interpreted by using the flux rope model of CMEs, in which the Hα dimmings represent the evacuated feet of the erupted flux rope. The mass supply of the halo CME could be coming from both the erupted flux rope itself and the lost material close to the flare footpoint regions as shown by Hα dimmings.
Awareness and knowledge of antimicrobial resistance and factors associated with knowledge among adults in Dessie City, Northeast Ethiopia: Community-based cross-sectional study

Background Antimicrobial resistance is an important global health challenge. The current study aimed to assess the level of awareness and knowledge of antimicrobial resistance and factors associated with knowledge among adults in Dessie City, Ethiopia. Methods A community-based cross-sectional study was conducted among 407 adults in Dessie City from June to July 2021. A systematic random sampling technique was used to select respondents, and Google Form was used to collect data online. The data was analyzed by SPSS Version 26. The associated factors of knowledge of antimicrobial resistance were identified by using bivariate and multivariable logistic regression. Independent variables with a P-value <0.2 were selected as candidate variables for multivariable logistic regression. Those variables with a P-value <0.05 were declared statistically significant factors. Result Out of the required sample sizes, four hundred and seven participants were enrolled, giving a response rate of 99.3%. One hundred and fifty-two (37.3%) respondents were females. Nearly one-third of the respondents (28.3%) have taken antibiotics in the last 6 months. In this study, 73.7% of study participants were aware of the existence of germs; 58.2% were aware of the existence of antibiotic resistance to bacteria; 47.7% were aware of the existence of drug resistance; 39.8% were aware of the existence of antimicrobial resistance; and 36.6% were aware of the existence of antibiotic resistance. Sixty-four (15.7%) respondents were not aware of any of the above terms. Sixty (14.7%) of the respondents were not aware of any risk factor for antimicrobial resistance. About 63 (15.5%) of the respondents did not know the consequences of antimicrobial resistance. Two hundred and thirty-eight (58.5%) respondents had good knowledge of antimicrobial resistance. In this study, being male (AOR = 1.99; 95% CI: 1.23,3.20), college and above educational level (AOR = 3.50; 95% CI: 1.08,11.39), grade 11–12 educational level (AOR = 3.73; 95% CI: 1.20,11.61), getting advice from health professionals about how to take antibiotics (AOR = 1.84; 95% CI:1.07,3.17), using health professionals as a source of information on antibiotics (AOR = 2.51; 95% CI: 1.48,4.25), and taking antibiotics without prescription (AOR = 1.86; 95% CI: 1.04,3.30) were significantly associated with good knowledge of antimicrobial resistance. Conclusion The study identified low awareness and knowledge of antimicrobial resistance among adults. Being male, higher educational level, getting advice from health professionals about how to take antibiotics, using health professionals as a source of information on antibiotics, and taking antibiotics without a prescription were significantly associated with good knowledge of antimicrobial resistance. Educational campaigns would be highly desirable for the public to improve their awareness and knowledge of antimicrobial resistance.
Treatment of pediatric patients with traumatic brain injury by Dutch Helicopter Emergency Medical Services (HEMS)

Background Sparse data are available on prehospital care by Helicopter Emergency Medical Service (HEMS) for pediatric patients with traumatic brain injury (TBI). This study focusses on prehospital interventions, neurosurgical interventions and mortality in this group. Methods We performed a retrospective analysis of pediatric (0–18 years of age) patients with TBI treated by Rotterdam HEMS. Results From January 2012 to December 2017 415 pediatric (<18 years of age) patients with TBI were included. Intubation was required in in 92 of 111 patients with GCS ≤ 8, 92 (82.9%), compared to 12 of 77 (15.6%) with GCS 9–12, and 7 of 199 (3.5%) with GCS 13–15. Hyperosmolar therapy (HSS) was started in 73 patients, 10 with a GCS ≤8. Decompressive surgery was required in 16 (5.8%), nine patients (56.3%) of these received HSS from HEMS. Follow-up data was available in 277 patients. A total of 107 (38.6%) patients were admitted to a (P)ICU. Overall mortality rate was 6.3%(n = 25) all with GCS ≤8, 15 (60.0%) died within 24 hours and 24 (96.0%) within a week. Patients with neurosurgical interventions (N = 16) showed a higher mortality rate (18.0%). Conclusions The Dutch HEMS provides essential emergency care for pediatric TBI patients, by performing medical procedures outside of regular EMS protocol. Mortality was highest in patients with severe TBI (n = 111) (GCS≤8) and in those who required neurosurgical interventions. Despite a relatively good initial GCS (>8) score, there were patients who required prehospital intubation and HSS. This group will require further investigation to optimize care in the future.
Conditional Permutation Tests and the Propensity Score in Observational Studies

Abstract In observational studies, the distribution of treatment assignments is unknown, and therefore randomization tests are not generally applicable. However, permutation tests that condition on sample information about the treatment assignment mechanism can be applicable in observational studies, provided treatment assignment is strongly ignorable. These tests use the conditional distribution of the treatment assignments given a sufficient statistic for the unknown parameter of the propensity score. Several tests that are commonly used in observational studies are particular instances of this general procedure. Moreover, conditional permutation tests and covariance adjustment are closely related, in the sense that the conditional permutation distribution of the covariance adjusted difference leads to the same inferences as the conditional permutation distribution of the unadjusted difference of sample means. A backtrack algorithm is developed to permit efficient calculation of the exact conditional si.
Time-use movement behaviors are associated with scores of depression/anxiety among adolescents: A compositional data analysis

Movement behaviors have been associated with mental health. The purposes of this study were to examine the association between movement behaviors and scores of depression/anxiety among adolescents and to determine the difference in depression/anxiety associated with reallocating time between different movement behaviors. This cross-sectional study included 217 Brazilian adolescents (15 to 18 years old, 49.3% female). Adolescents wore an accelerometer for one week to assess the four-movement behaviors which include sleep, sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA). The depression/anxiety score was calculated by factor analysis using the 12-item General Health Questionnaire. Compositional data analyses were used to examine the association between movement behavior and the depression/anxiety score. Compositional isotemporal substitution models estimated the change in depression/anxiety score associated with reallocating 10, 30, and 60 min between movement behaviors. The composition of movement behaviors was significantly associated with depression/anxiety scores (p < 0.05). Replacing time from SB to LPA was associated with improvement in the depression/anxiety score, while the inverse was associated with an increase in this score. Replacing time of LPA with MVPA was associated with worsening in the depression/anxiety score. The 24-h time distribution of the day may play a crucial role in mental health. Compositions with more time spent in LPA at the expense of less SB are associated with improvement in the scores of depression/anxiety. The type of MVPA may moderate its effects on depression/anxiety in adolescents. Holistic interventions including the full range of movement behaviors may be a gateway to reduce the levels of depression/anxiety in adolescence.
Exploring reproductive trajectories of youths of Oromia, Ethiopia: A life course approach

In the context of continuous cultural, social, and economic changes happening around the globe, the predictable patterns of the life course of the past observed over successive birth cohorts will not remain stable across generations. In this study, three reproductive role indicators—first sexual encounter, first marriage, and first birth–for three synthetic birth cohorts were used to identify and characterize the reproductive trajectories of youths. In our analysis, for the sake of comparison with global literature, we considered youths to be between ages 15 and 24. The analysis was conducted using data extracted from the 2005, 2011, and 2016 Ethiopian Demographic Health Survey for Oromia National Regional State. Three synthetic birth cohorts of youths of birth years between 1975 and 1989 were constructed for the analysis. A sequence analysis based on dynamic hamming distance with partition around medoids technique was employed to extract the typologies of reproductive trajectories of youths. In addition, discrepancy analysis and a sequence regression tree analysis were employed to characterize the identified typologies of trajectories. Data management was done using STATA 14 and all analyses were carried out using R software. The study identified four different typologies of reproductive trajectories among the youth. The sex of respondents was the primary discriminating factor of the typologies of reproductive trajectories. The findings support the notion of changing norms in reproductive behavior among the less educated youth irrespective of sex. The discriminating power of education was stronger for female youth in urban areas than rural females. It implies that the postponement of reproductive role assumption was stronger among educated female youths residing in urban than their rural counterparts. Normative reproductive practices such as early marriage and adolescent fertility are still common practices that require efforts of communities and local government bodies to ameliorate these practices. Results of the study indicate that less educated youth should be targeted in programs that aim at improving youth empowerment (i.e., training and employment opportunities) as well as their sexual and reproductive health.
Assessment of heterocyclic aromatic amines contents in flamed and braised chicken in Burkina Faso

The nutritional status of meat is tarnished by its association with the induced cooking contaminants. The aim of this study was to assess the heterocyclic aromatic amines profile and contents in processed chicken in Burkina Faso. Eight polar and apolar heterocyclic aromatic amines (HAAs) including 2-mino-3-methylimidazo[4,5-f]quinolone (IQ), 3-amino-1,4-dimethyl-5H-pyrido[4, 3-b]indole (Trp-P1), 3-amino-1-methyl-5H-pyrido[4,3-b]indole (Trp-P2), 2-mino-9H-pyrido-[2,3-b]indole (AαC), 2-amino-1-methyl-6-phenylimidazo[4, 5– ]pyridine (PhIP), 2-amino-3-methyl-9H-pyrido[2,3-b] indole (MeAαC), 2-amino-3,4,8-rimethylimidazo[4,5-f]quinoxaline (4,8-DiMeIQx) and 2-amino-3,8-imethylimidazo[4,5–]quinoxaline (MeIQx) were screened by high performance liquid chromatography from 29 samples of flamed chicken and 66 samples of braised chicken collected in Ouagadougou city. Apolar HAAs and polar HAAs were respectively 12 and 3 times more abundant in flamed chickens (32.66±10 and 3.48±10.39 ng/g, respectively) than in braised chickens (2.70±9.67 and 0.92 ng/g, respectively). The maximum levels of AαC were in the same proportions in flamed (12.01 ng/g) and braised chickens (14.13 ng/g). Flamed chicken had the highest Trp-P1 content (530.31 ng/g). The 4,8-DiMeIQx was not detected in braised chicken. The AαCs were more abundant in flamed than in braised chicken. The profile and the contents of the HAAs in processed chicken are related to cooking methods. Because of the high variability observed on the obtained concentrations, investigations on the contents of precursors in raw chicken, the effect of marinating ingredients on the formation of HAAs are needed.
Uptake of appointment spacing model of care and associated factors among stable adult HIV clients on antiretroviral treatment Northwest Ethiopia

Introduction Ethiopia launched an Appointment Spacing Model in 2017, which involved a six-month clinical visit and medication refill cycle. This study aimed to assess the uptake of the Appointment Spacing Model of care and associated factors among stable adult HIV clients on ART in Ethiopia. Methods A cross-sectional study was conducted from October 3 to November 30, 2020 among 415 stable adult ART clients. EpiData version 4.2 was used for data entry and SPSS version 25 was used for cleaning and analysis. A multivariable logistic regression model was fitted to identify associated factors, with CI at 95% with AOR being reported to show the strength of association. Results The uptake of the appointment spacing model was 50.1%. Residence [AOR: 2.33 (95% CI: 1.27, 4.26)], monthly income [AOR: 2.65 (95% CI: 1.13, 6.24)], social support [AOR: 2.21 (95% CI: 1.03, 4.71)], duration on ART [AOR: 2.41 (95% CI: 1.48, 3.92)], baseline regimen change [AOR: 2.20 (95% CI: 1.02, 4.78)], viral load [AOR: 2.80 (95% CI: 1.06, 7.35)], and alcohol abstinence [AOR: 2.02 (95% CI: 1.21, 3.37)] were statistically significant. Conclusions The uptake of the ASM was low. Behavioral change communication, engaging income-generating activities, and facility-level service providers’ training may improve the uptake.
