Background: As COVID-19 occurs suddenly and is highly contagious, this will inevitably cause people anxiety, depression, etc. The study on the public psychological states and its related factors during the COVID-19 outbreak is of practical significance. Methods: 600 valid questionnaires were received. The Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS) were used. Results: Females' anxiety risk was 3.01 times compared to males (95% CI 1.39-6.52). Compared with people below 40 years old, the anxiety risk of people above 40 years old was 0.40 times (95% CI 0.16-0.99). SDS results indicated that the difference between education level and occupation was statistically significant (p = 0.024, 0.005). Compared to people with a master's degree or above, those with a bachelor's degree group had a depression risk of 0.39 times (95% CI 0.17-0.87). Compared with professionals, industrial service workers and other staff had a depression risk of 0.31 times (95% CI 0.15-0.65) and 0.38 times (95% CI 0.15-0.93). Conclusions: 600 questionnaire participants were psychologically stable. Non-anxiety and non-depression rates were 93.67% and 82.83%, respectively. There were anxiety in 6.33% and depression in 17.17%. Therefore, we should pay attention to the psychological states of the public. ARTICLE HISTORY
52Alzheimer's disease (AD) is a complex and heterogenous brain disease that affects multiple inter-related 53 biological processes. This complexity contributes, in part, to existing difficulties in the identification of 54 successful disease-modifying therapeutic strategies. To address this, systems approaches are being used to 55 characterize AD-related disruption in molecular state. To evaluate the consistency across these molecular 56 models, a consensus atlas of the human brain transcriptome was developed through coexpression meta-57 analysis across the AMP-AD consortium. Consensus analysis was performed across five coexpression 58 methods used to analyze RNA-seq data collected from 2114 samples across 7 brain regions and 3 research 59 studies. From this analysis, five consensus clusters were identified that described the major sources of 60 AD-related alterations in transcriptional state that were consistent across studies, methods, and samples. 61AD genetic associations, previously studied AD-related biological processes, and AD targets under active 62 investigation were enriched in only three of these five clusters. The remaining two clusters demonstrated 63 strong heterogeneity between males and females in AD-related expression that was consistently observed 64 across studies. AD transcriptional modules identified by systems analysis of individual AMP-AD teams 65 were all represented in one of these five consensus clusters except ROS/MAP-identified Module 109, 66 which was specific for genes that showed the strongest association with changes in AD-related gene 67 expression across consensus clusters. The other two AMP-AD transcriptional analyses reported modules 68 that were enriched in one of the two sex-specific Consensus Clusters. The fifth cluster has not been 69 previously identified and was enriched for genes related to proteostasis. This study provides an atlas to 70 map across biological inquiries of AD with the goal of supporting an expansion in AD target discovery 71 efforts.
Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m 2 . In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, the...
CSC is characterized by a thinned inner choroidal layer and enlarged underlying hyporeflective choroidal lumina in all eyes, in addition to a dome-shaped RPE elevation, a double-layer sign of the RPE/Bruch's membrane complex, and RPE microrips in some eyes. EDI-OCT may be helpful in the diagnosis of CSC.
ObjectivesTo investigate vascular flow density in pathological myopia with optical coherence tomography (OCT) angiography.DesignA prospective comparative study was conducted from December 2015 to March 2016.SettingParticipants were recruited in Beijing Tongren Hospital.ParticipantsA total of 131 eyes were enrolled, which were divided into three groups: 45 eyes with emmetropia (EM; mean spherical equivalent (MSE) 0.50D to −0.50D), 41 eyes with high myopia (HM; MSE ≤−6.00D, without pathological changes), and 45 eyes with pathological myopia (PM; MSE ≤−6.00D and axial length (AL) ≥26.5 mm, and with pathological changes).Main outcome measuresMacular, choriocapillaris and radial peripapillary capillary (RPC) flow densities were measured and compared between groups, and their relationships with AL and best corrected visual acuity (BCVA) were analysed.ResultsSignificant differences were found in macular, choriocapillaris and RPC flow densities among the three groups (p<0.05). Multiple comparisons revealed that, compared with the EM and HM groups, macular and RPC flow densities of the PM group were significantly decreased (p<0.05), but no significant difference in choriocapillaris flow density was found between the PM and HM groups (p=0.731). Compared with the EM group, retinal flow density in the macular and arcuate fibre region was not decreased in the HM group. In addition, there was a negative correlation between AL and superficial macular flow density (β=−0.542, p<0.001), deep macular flow density (β=−0.282, p=0.002) and RPC flow density (β=−0.522, p<0.001); and a positive correlation between BCVA and superficial macular flow density (β=0.194, p=0.021), deep macular flow density (β=0.373, p<0.001), and choriocapillaris flow density (β=0.291, p=0.001).ConclusionsMacular and RPC flow densities decreased in pathological myopia compared with high myopia and emmetropia. No significant decrease of retinal flow density in the macular and arcuate fibre region was found in high myopic eyes compared with emmetropic eyes. Moreover, macular and RPC flow densities were negatively related to AL, and macular flow density was positively related to BCVA.
. Purpose: To measure the hyporeflective lumen in the choroid of patients with central serous choroidopathy (CSC) and to compare the diameter with that of a control group. Methods: The prospective comparative observational clinical study included patients with unilateral CSC and a control group of normal subjects, matched in age, gender and refractive error with the study group. Subfoveal choroidal thickness (SFCT) and the largest diameter of choroidal hyporeflective lumen as surrogates for the choroidal vessels were measured by enhanced depth imaging optical coherence tomography (OCT). Results: The study group included 15 Chinese patients and the control group 15 control subjects. Mean SFCT was significantly (p = 0.04) larger in the affected eyes (455 ± 73 μm) than in the contralateral unaffected eyes (387 ± 94 μm), in which it was significantly (p = 0.005) larger than in the control group (289 ± 71 μm). In a parallel manner, the mean diameter of the largest hyporeflective lumen was larger, but not significantly larger (p = 0.18) in the affected eyes (305 ± 101 μm) than in the in the contralateral unaffected eyes (251 ± 98 μm), in which it was significantly (p = 0.001) larger than in the control group (140 ± 40 μm). Largest vessel diameter was significantly (p < 0.001; correlation coefficient: 0.73) correlated with the thickness of the total choroid. Conclusions: In patients with CSC, the affected eyes show larger hyporeflective lumen than the contralateral clinically unaffected eyes and significantly larger than normal control eyes. Assuming these hyporeflective lumens to be choroidal vessels, macular swelling in CSC is markedly associated with vascular engorgement. As also the clinically unaffected eyes showed macular choroidal significant swelling, CSC may have a systemic component with usually asymmetric ocular involvement.
Repositioning of the global epicentre of non-optimal cholesterol NCD Risk Factor Collaboration (NCD-RisC)* High blood cholesterol is typically considered a feature of wealthy western countries 1,2. However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world 3 and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health 4,5. However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low-and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium,
