Although results showed low levels of WG knowledge and practices, this study still supports positive attitudes to acquire WG-related knowledge among college students in Chongqing, China.

This study estimated the prevalence of uncorrected refractive error (URE) and its determinants in a socially vulnerable older population living in Armenia.

The study design used in the stidy is a cross-sectional study.

A total of 485 people responded to a survey on sociodemographic characteristics, spectacle use, and ophthalmic services' use. All participants underwent a comprehensive ophthalmic examination including assessment of presenting and best-corrected visual acuity, measuring intraocular pressure and dilated eye fundus examination. Patients who had presenting visual acuity (<6/12) but improved≥one line with/without available spectacles after refraction in the better eye were considered to have URE. Descriptive statistics described the sample and estimated the prevalence of the URE in the population. Logistic regression models were used to evaluate its determinants.

The mean age of participants was 74.5 (7.27) years, ranging from 51 to 94 years. Women constituted the majority of participants (86%). The prevalence of URE in the better eye was 26%. In bivariate analysis, those who were older and who had less than 10 years of education had higher odds of URE than younger and more educated respondents. In multivariable analysis, only education remained associated with URE (OR=3.71; 95% CI 1.10-12.5). The rate of normal vision (≥6/12) improved from 58.9% to 81.5%, whereas the rate of visual impairment (<6/12) decreased from 41.1% to 18.5% after best correction in the better eye.

The prevalence of URE was high in this study population. The findings warrant the need for eye screening and provision of affordable spectacle correction to the target population in Armenia.

We aimed to determine whether there are any differences in all-cause and cause-specific mortality with cardiovascular disease (CVD) risk between health screening attenders and non-attenders among young adults.

We performed a retrospective cohort study using claim data from the Korean National Health Insurance Service database.

Individuals aged 20-39 years who had received health screening at least once between 2002 and 2005 were classified as attenders, and the others were classified as non-attenders. After propensity score matching according to attendance of health screening, 2,060,409 attenders and 2,060,409 non-attenders were included. We estimated adjusted hazard ratios (HRs) and 95% confidence interval (CI) for all-cause mortality, cause-specific mortality, and hospitalization of CVD from 2006 to 2015.

Survival from all-cause mortality was greater among attenders than among non-attenders (log rank P<0.001). Similarly, death from CVD (log rank P=0.007) and CVD events (log rank P<0.001) were less likely among attenders. The risk for all-cause mortality in attenders was significantly lower than that in non-attenders (HR=0.83, 95% CI=0.81 to 0.84). The risk for CVD mortality (HR=0.80, 95% CI=0.73 to 0.87) and hospitalization of CVD (HR=0.92, 95% CI=0.91 to 0.94) were lower in attenders. In stratified analyses, the risk for all-cause and cause-specific mortalities was lower among attenders regardless of insurance type.

Among young adults, the risk for all-cause mortality, CVD mortality, and hospitalization of CVD were lower for those who underwent health screenings. Future studies that evaluate the cost-effectiveness of health screening with additional consideration of psychosocial aspects are needed.

The specific role of each receptor subtype to the pharmacological effects of antipsychotic drugs remains unclear. Understanding the relationship between antipsychotic drugs and their binding affinities at DA and 5-HT receptor subtypes is very important for antipsychotic drug discovery and could lead to new drugs with enhanced efficacies. We have previously disclosed SYA16263 (5) as an interesting compound with moderate radioligand binding affinity at the D2 & D3 receptors (Ki = 124 nM & 86 nM respectively) and high binding affinities towards D4 and 5-HT1A receptors (Ki = 3.5 nM & 1.1 nM respectively). Furthermore, we have demonstrated SYA16263 (5) is functionally selective and produces antipsychotic-like behavior but without inducing catalepsy in rats. Based on its pharmacological profile, we selected SYA16263 (5) to study its structure-affinity relationship with a view to obtaining new analogs that display receptor subtype selectivity. In this study, we present the synthesis of structurally modified SYA16263 (5) analogs and their receptor binding affinities at the DA and 5-HT receptor subtypes associated with antipsychotic action. Furthermore, we have identified compound 21 with no significant binding affinity at the D2 receptor subtype but with moderate binding affinity at the D3 and D4 receptors subtypes. However, because 21 is able to demonstrate antipsychotic-like activity in a preliminary test, using the reversal of apomorphine-induced climbing behavior experiment in mice with SYA16263 and haloperidol as positive controls, we question the essential need of the D2 receptor subtype in reversing apomorphine-induced climbing behavior.Recent research suggests that young children are capable of distinguishing between phonetically dissimilar spoken accents yet have difficulty in distinguishing between phonetically similar accents. The current studies aimed to determine whether the presence of dialect-specific vocabulary enhances young children's ability to categorize speakers. In Study 1, 4- to 7-year-old children performed tasks in which they matched speakers based on the dialect-specific vocabulary the speakers used. Participants were successful in matching speakers based on vocabulary at a rate significantly greater than chance. In Study 2, participants performed a task in which they inferred a speaker's future dialect-specific vocabulary use based on the speaker's previous vocabulary use. Participants were able to infer a speaker's vocabulary use at a rate significantly greater than chance, and participants also showed social preference for and selective trust of speakers who used the participants' native dialect vocabulary over those who used a non-native dialect vocabulary. These interesting results suggest that when accent differences are too subtle for children to categorize speakers, dialect-specific vocabulary may enhance young children's ability to categorize a speaker. The results of preference and selective trust questions also suggest that children as young as 4 years use their knowledge of a speaker's vocabulary to guide their preferred social interactions, choosing to interact with others who speak similarly to them.

Hip capsulotomies, performed routinely during hip arthroscopy, can contribute to adverse joint kinematics. Direct repair is not always feasible. Therefore, the aim of this study was to evaluate the biomechanics of a conventional all-suture repair versus a hybrid suture and anchor-based capsular repair.

Nine paired (n=18) hips were tested on a joint-motion simulator, utilizing optical trackers to capture kinematic data. Pairs were randomly allocated to capsular repair type and tested as (1) intact, (2) after T-capsulotomy, and (3) repair each at 0°, 45°, and 90° flexion. Internal and external rotation torques and abduction/adduction torques of 3N·m were applied and rotational range of motion and joint translations recorded.

At 0°, following repair there were no significant differences in joint rotation or translations between repairs (p>0.134). At 45°, both repair types restored motion to near intact values, with no significant differences between groups. Similarly, there were no significant differences in joint translations between repairs. At 90°, both types of capsular repair failed to restore rotational range of motion, with persistent increases in motion (47.0±16.7°) compared to the intact condition (44.1±15.8°, p=0.006); however, there were no significant differences between repair groups. There were no significant differences in joint translations between repairs.

Use of a hybrid repair produced comparable joint rotation and translation under all testing conditions as an all-suture repair. As such, this technique represents a viable option for capsular repair where proximal capsular tissue is deficient.

Currently, there are two rapid antigen detection (RAD) kits from the WHO Emergency Use List for detecting SARS-CoV-2.

The Panbio COVID-19 Ag Rapid Test Device was selected to evaluate the performance for detecting SARS-CoV-2.

Analytical sensitivity for the detection of SARS-CoV-2 virus was determined by limit of detection (LOD) using RT-PCR as a reference method. Clinical sensitivity was evaluated by using respiratory specimens collected from confirmed COVID-19 patients.

The LOD results showed that the RAD kit was 100 fold less sensitive than RT-PCR. Clinical sensitivity of the RAD kit was 68.6 % for detecting specimens from COVID-19 patients.

The RAD kit evaluated in the present study shared similar performance with another kit from the WHO Emergency Use List, the Standard Q COVID-19 Ag. Understanding the clinical characteristics of RAD kits can guide us to decide different testing strategies in different settings.

To understand how force transmission occurs in relation to the distal joint in a feline limb, which transfers bodyweight to the ground, it is necessary to examine the internal stress distribution of the distal joint limb in detail. Therefore, finite element models (FEM) of a healthy feline were established to predict the internal stress distribution of the distal limb. The FEM model included 23 bony components, various cartilaginous ligaments, as well as the encapsulated soft tissue of the paw. The FEM model was validated by comparison of paw pressure distribution, obtained from an experiment for balance standing. The results demonstrated a good agreement between the experimentally measured and numerically predicted pressure distribution in the feline paw. Additionally, higher stress levels were noted in the metacarpal segment, with smaller stresses observed in the phalanges portion including the proximal, middle, and distal segments.
