TL;DR: Wang et al. as discussed by the authors examined changes in depression and anxiety among Chinese adolescents during the COVID-19 epidemic, and explore factors associated with depression, including female gender, senior secondary school enrollment, and concerns about entering a higher grade.
Abstract: The 2019 coronavirus disease (COVID-19) is a public health emergency of international concern. In China, all schools were shut down and students were home quarantined to prevent disease spread; these steps could have potential negative effects on mental health of adolescents. This study aimed to examine changes in depression and anxiety among Chinese adolescents during the COVID-19 epidemic, and explore factors associated with depression and anxiety. Two survey administrations were conducted among Chinese adolescents between February 20 and February 27 and between April 11 and April 19, 2020, respectively. The Center for Epidemiological Studies-Depression Scale (CES-D) and the 7-item Generalized Anxiety Disorder (GAD-7) scale were used to assess depressive symptoms and anxiety symptoms, respectively. A total of 9554 and 3886 adolescents participated in the first and second surveys. During the initial survey, the prevalence of depression was 36.6% (95% CI: 35.6-37.6%) while the prevalence of anxiety was 19% (95% CI: 18.2-19.8%). Rates of depression and anxiety increased to 57.0% (95% CI: 55.4-58.6%) and 36.7% (95% CI: 35.2-38.2%), respectively, in the second survey. Multivariable logistic regression analyses revealed that group membership in the second survey, female gender, senior secondary school enrollment, and concerns about entering a higher grade were positively associated with both depression and anxiety. Conversely, a sleep duration of ≥6 h/day, an exercise duration ≥30 min/day, having the same as typical or higher study efficiency during the COVID-19 outbreak, and living in provinces with 1000-9999 confirmed COVID-19 cases were negatively associated with depression and anxiety. In conclusion, compared to figures reported during the COVID-19 outbreak, the prevalence of depression and anxiety in Chinese adolescents significantly increased after the initial outbreak. Regular screening and appropriate interventions are urgently needed to reduce the risk for emotional disturbances among adolescents during and after the initial COVID-19 outbreaks.

TL;DR: Wang et al. as mentioned in this paper examined the attitudes of Chinese college students toward COVID-19 vaccines and their associated factors, and found that those who were concerned about being infected with COVID19 (very much vs no, OR=1.660, p<0.001) were more likely to accept a vaccine in the future.
Abstract: Background: Vaccination is an important preventative measure against the coronavirus disease 19 (COVID-19) pandemic. To implement vaccination and immunization programs effectively, it is essential to investigate public attitudes toward COVID-19 vaccines. This study examined the attitudes of Chinese college students toward COVID-19 vaccines and their associated factors. Methods: A cross-sectional study was conducted in college students nationwide from December 27, 2020 to January 18, 2021. Attitudes toward COVID-19 vaccines and acceptance of future vaccination programs were assessed. Results: Totally, 2,881 college students participated in this survey; of them, 76.3% (95% CI: 74.8% - 77.9%) were willing to accept a COVID-19 vaccine in the future. Multiple logistic analysis revealed that students living in urban (OR=1.409, 95% CI: 1.152 - 1.724, p=0.001) and those studying health-related courses (OR=1.581, 95% CI: 1.291 - 1.935, p<0.001) were more likely to have a positive attitude toward COVID-19 vaccines. In addition, those who were worried about being infected with COVID-19 (very much vs no, OR=1.690, 95% CI: 1.212-2.356, p=0.002), heard previously about COVID-19 vaccines (OR=1.659, 95% CI: 1.268-2.170, p<0.001), believed that vaccines are safe (Yes vs No, OR=3.570, 95% CI: 1.825-6.980), thought that vaccines can protect people from being infected with COVID-19 (Yes vs No, OR=1.957, 95% CI: 1.286-2.979, p=0.002), and had encouraged their family and friends to have a vaccine (Yes vs No, OR=17.745, 95% CI: 12.271-25.660, p<0.001) had higher acceptance of COVID-19 vaccination. Conclusions: A high rate of acceptance of COVID-19 vaccines was found among Chinese college students. However, vaccine uptake may be reduced by concerns about vaccine safety and efficacy. Alleviating these concerns and enhancing public confidence in vaccines are crucial for future immunization programs against the COVID-19 pandemic.

TL;DR: Depression was common among female adolescents during the COVID-19 outbreak in mainland China, and older age, distant learning, concern about CO VID-19, short sleep duration, and physical exercise duration represented the independent factors for suffering from depression.
Abstract: The outbreak of 2019 coronavirus disease (COVID-19) could increase the risk of depression. However, epidemiological data on outbreak-associated depressive morbidity of female adolescents are not available. This study determines the incidence and correlates of depression among female adolescents aged 11–18 years during the COVID-19 outbreak in mainland China. A large cross-sectional sample, nationwide online survey was conducted during the COVID-19 outbreak. Depression was assessed using the Center for Epidemiologic Studies Depression Scale (CES-D), and the correlative factors of depression were analyzed. In this study, 4805 female adolescents were enrolled with a median (range) age of 15 (11–18) years. Of them, 1899 (39.5%) suffered from depression with a CES-D score of > 15. The onset of depression was significantly related to age, grade, distant learning, attitude toward COVID-19, sleep duration, and physical exercise duration. Furthermore, participants aged 15–18 years (OR = 1.755, 95% CI: 1.550–1.987, p < 0.001), participating in distant learning (OR = 0.710, 95% CI: 0.564–0.894, p = 0.004), concerned about COVID-19 (OR = 0.414, 95% CI: 0.212–0.811, p = 0.010), with sleep duration/day of < 6 h (OR = 2.603, 95% CI: 1.946–3.483, p < 0.001),and with physical exercise duration/day < 30 min (OR = 1.641, 95% CI: 1.455–1.850, p < 0.001) represented to be independent factors for suffering from depression. During the COVID-19 outbreak, depression was common among female adolescents. Older age, distant learning, concern about COVID-19, short sleep duration, and physical exercise duration represented the independent factors for suffering from depression.

TL;DR: A meta-analysis of the prevalence of poor sleep quality and its mediating factors in medical students found that regular screening of poorSleep quality and effective interventions are needed for medical students.
Abstract: Poor sleep quality is common in medical students and is associated with a number of negative health outcomes. However, the prevalence estimates of poor sleep quality in medical students vary widely across studies. We thus conducted a meta-analysis of the prevalence of poor sleep quality and its mediating factors in medical students. A systematic literature search of PubMed, EMBASE, Web of Science, PsycINFO, and Medline Complete was performed. The random-effects model was used to analyze the pooled prevalence of poor sleep quality and its 95% confidence intervals (CIs). A total of 57 studies with 25,735 medical students were included. The pooled prevalence of poor sleep quality was 52.7% (95% CI: 45.3% to 60.1%) using the Pittsburgh Sleep Quality Index (PSQI). The pooled mean total PSQI score across 41 studies with available data was 6.1 (95% CI: 5.6 to 6.5). Subgroup analyses found that PSQI cutoff value and study region were associated with the prevalence of poor sleep quality (P = 0.0003 VS. P = 0.005). Across the continents, poor sleep quality was most common in Europe, followed by the Americas, Africa, Asia, and Oceania. Meta-regression analyses found that smaller sample size (slope = − 0.0001, P = 0.009) was significantly associated with higher prevalence of poor sleep quality. Poor sleep quality is common among medical students, especially in Europe and the Americas continets. Due to the negative health outcomes, regular screening of poor sleep quality and effective interventions are needed for medical students.

TL;DR: This is the first study presenting information about the mental health status of Ecuadorians in epidemiological surveillance during the pandemic, however, the data did not confirm that the presence of psychological symptoms was a product of being under surveillance.
Abstract: at all. Future studies might pay attention to the protective factors of those participants who did not present psychological symptoms even if they were experiencing confinement, isolation, mourning the loss of the loved ones, the presence of physical symptoms produced by COVID-19, or the lack of appropriate health care. To the authors best knowledge this is the first study presenting information about the mental health status of Ecuadorians in epidemiological surveillance during the pandemic, however, our data did not confirm that the presence of psychological symptoms was a product of being under surveillance. It is necessary to assess general population to reach such conclusions.

TL;DR: In this paper, the global prevalence of clinically elevated depression and anxiety in children and adolescents during the COVID-19 global mental health pandemic has been investigated, and a search strategy combined search terms from three themes: (1) mental illness, (2) mental health, (3) adolescents (age ≤ 18 years), and (4) children/adolescent were used.
Abstract: Importance Emerging research suggests that the global prevalence of child and adolescent mental illness has increased considerably during COVID-19. However, substantial variability in prevalence rates have been reported across the literature. Objective To ascertain more precise estimates of the global prevalence of child and adolescent clinically elevated depression and anxiety symptoms during COVID-19; to compare these rates with prepandemic estimates; and to examine whether demographic (eg, age, sex), geographical (ie, global region), or methodological (eg, pandemic data collection time point, informant of mental illness, study quality) factors explained variation in prevalence rates across studies. Data Sources Four databases were searched (PsycInfo, Embase, MEDLINE, and Cochrane Central Register of Controlled Trials) from January 1, 2020, to February 16, 2021, and unpublished studies were searched inPsycArXivon March 8, 2021, for studies reporting on child/adolescent depression and anxiety symptoms. The search strategy combined search terms from 3 themes: (1) mental illness (including depression and anxiety), (2) COVID-19, and (3) children and adolescents (age ≤18 years). ForPsycArXiv, the key termsCOVID-19,mental health, andchild/adolescentwere used. Study Selection Studies were included if they were published in English, had quantitative data, and reported prevalence of clinically elevated depression or anxiety in youth (age ≤18 years). Data Extraction and Synthesis A total of 3094 nonduplicate titles/abstracts were retrieved, and 136 full-text articles were reviewed. Data were analyzed from March 8 to 22, 2021. Main Outcomes and Measures Prevalence rates of clinically elevated depression and anxiety symptoms in youth. Results Random-effect meta-analyses were conducted. Twenty-nine studies including 80 879 participants met full inclusion criteria. Pooled prevalence estimates of clinically elevated depression and anxiety symptoms were 25.2% (95% CI, 21.2%-29.7%) and 20.5% (95% CI, 17.2%-24.4%), respectively. Moderator analyses revealed that the prevalence of clinically elevated depression and anxiety symptoms were higher in studies collected later in the pandemic and in girls. Depression symptoms were higher in older children. Conclusions and Relevance Pooled estimates obtained in the first year of the COVID-19 pandemic suggest that 1 in 4 youth globally are experiencing clinically elevated depression symptoms, while 1 in 5 youth are experiencing clinically elevated anxiety symptoms. These pooled estimates, which increased over time, are double of prepandemic estimates. An influx of mental health care utilization is expected, and allocation of resources to address child and adolescent mental health concerns are essential.

TL;DR: In this article, a review outlines the current understanding of miRNA target recognition in animals and discusses the widespread impact of miRNAs on both the expression and evolution of protein-coding genes.
Abstract: MicroRNAs (miRNAs) are endogenous ∼23 nt RNAs that play important gene-regulatory roles in animals and plants by pairing to the mRNAs of protein-coding genes to direct their posttranscriptional repression. This review outlines the current understanding of miRNA target recognition in animals and discusses the widespread impact of miRNAs on both the expression and evolution of protein-coding genes.

TL;DR: The data shows clearly the need for EEO initiatives for women within the health service and identifies the areas of greatest concern.
Abstract: If equal employment opportunities were a reality, one would expect all salaries to be more or less randomly distributed between the genders. The data does not show random distribution. Of the awards studied in depth, 11 of the 18 showed a statistically significant different salary between women and men. Two awards had a marginal probability of significance, and five had a probability of significance of less than five per cent. The data shows clearly the need for EEO initiatives for women within the health service and identifies the areas of greatest concern. The many questions raised through this general analysis of the data will guide further research and the development of an EEO management plan that is specific to the needs of the Palmerston North Area Health Board. Also highlighted is the need for similar statistics showing the composition of the workforce by ethnicity and disability. Only when this has been obtained and analysed can specifically targeted EEO programmes be developed to meet the workforce needs of the Board. Other Boards interested in receiving a statistical analysis of their workforce by gender should contact Patrick Mulcahy at the National Health Statistics Centre, Private Bag 2, Upper Willis Street, Wellington, phone (04) 844-167.

TL;DR: In this article, the authors evaluated the impact of the COVID-19 pandemic on adolescent mental health and found that adolescents of varying backgrounds experience higher rates of anxiety, depression, and stress due to the pandemic.
Abstract: Due to lack of sufficient data on the psychological toll of the COVID-19 pandemic on adolescent mental health, this systematic analysis aims to evaluate the impact of the pandemic on adolescent mental health. This study follows the PRISMA guidelines for systematic reviews of 16 quantitative studies conducted in 2019–2021 with 40,076 participants. Globally, adolescents of varying backgrounds experience higher rates of anxiety, depression, and stress due to the pandemic. Secondly, adolescents also have a higher frequency of using alcohol and cannabis during the COVID-19 pandemic. However, social support, positive coping skills, home quarantining, and parent–child discussions seem to positively impact adolescent mental health during this period of crisis. Whether in the United States or abroad, the COVID-19 pandemic has impacted adolescent mental health. Therefore, it is important to seek and to use all of the available resources and therapies to help adolescents mediate the adjustments caused by the pandemic.

TL;DR: This review highlights the urgent need for practitioners and policymakers to attend to and collaborate with children and adolescents, especially those in higher risk subgroups, to mitigate short‐ and long‐term pandemic‐associated mental health effects.
Abstract: BACKGROUND: The COVID-19 pandemic has posed an unprecedented threat to global mental health. Children and adolescents may be more susceptible to mental health impacts related to their vulnerable developmental stage, fear of infection, home confinement, suspension of regular school and extracurricular activities, physical distancing mandates, and larger scale threats such as global financial recessions and associated impacts. Our objective was to review existing evidence of the COVID-19 pandemic's global impact on the mental health of children and adolescents 3,000 chart reviews. A high prevalence of COVID-19-related fear was noted among children and adolescents, as well as more depressive and anxious symptoms compared with prepandemic estimates. Older adolescents, girls, and children and adolescents living with neurodiversities and/or chronic physical conditions were more likely to experience negative mental health outcomes. Many studies reported mental health deterioration among children and adolescents due to COVID-19 pandemic control measures. Physical exercise, access to entertainment, positive familial relationships, and social support were associated with better mental health outcomes. CONCLUSIONS: This review highlights the urgent need for practitioners and policymakers to attend to and collaborate with children and adolescents, especially those in higher risk subgroups, to mitigate short- and long-term pandemic-associated mental health effects.
