In this study, we tested the validity of the modified version of the Vaccine Attitude Question Battery (VAQB) across 22 different languages. Validity test was conducted with a large-scale international survey dataset, COVIDiSTRESSII Global Survey, collected from 20,601 participants from 62 countries. We employed exploratory and confirmatory factor analysis, measurement invariance test, and measurement alignment for internal validity test. Moreover, we examined correlation between the VAQB score, vaccination intent, compliance with preventive measures, and trust in public health-related agents. The results reported that the modified VAQB, which included five items, showed good validity across 22 languages with measurement alignment. Furthermore, the VAQB score showed negative association with vaccination intent, compliance, and trust as expected. The findings from this study provide additional evidence supporting the validity of the modified VAQB in 22 languages for future large-scale international research on COVID-19 and vaccination.

In this study, we tested the validity across two scales addressing conspiratorial beliefs that may influence behaviors related to public health, government, and the COVID-19 pandemic. The 4-item Conspiratorial Thinking Scale and 3-item Anti-Expert Sentiment Scale were validated across 24 languages and dialects using the COVIDiSTRESSII Global Survey dataset, with 12,261 participants who completed the survey in languages with greater than 100 participants per language. We employed confirmatory factor analysis, measurement invariance test, and measurement alignment for internal consistency testing. To test convergent validity of the two scales, we assessed correlations with trust in seven agents related to government, science, and public health. Although scalar invariance was not achieved when measurement invariance test was conducted initially, we found that both scales can be employed in further international studies with measurement alignment. Moreover, both conspiratorial and anti-expert beliefs were significantly and negatively correlated with trust in all agents. Findings from this study provide supporting evidence for the validity of both scales across 24 languages for future large-scale international research.

Middle East Respiratory Syndrome (MERS) induced by new ß coronavirus MERS-(CoV) had first been described in Saudi Arabia in September 2012. MERS-CoV communication inside the population is often identified with clustered households and cramped communal spaces. The purpose of the study is to assess the knowledge and awareness of MERS-CoV among dental students in India. This was a questionnaire-based cross-sectional survey of 100 dental college students in Chennai. The self-designed questionnaires contained ten questions focused on the knowledge and awareness of MERS-CoV amongst dental college students. Questionnaires were circulated through an online website survey planet. After the responses were received from 100 participants, data were collected and analyzed, .87% are aware of MERS-CoV through media 13% from professional channels. 84%are aware of the clinical manifestation of MERS-CoV. 81%Are aware of the mode of transmission of MERS-CoV. 76%are aware of the preventive measures against MERS -CoV.68%. Are aware of the incubation period of MERS-CoV. 74%aware of PCR as a diagnostic test for MERS-CoV. This study concluded that dental students had strong awareness and knowledge of MERS. Also, there are a few differences in information and behaviours that require change. Large-scale health educational programs on MERS also should be facilitated by professional organizations to expand their reach and to strengthen knowledge to have a positive impact on their behaviour.

: In this letter, the psychological impact of COVID-19 on cancer infected patients is discussed. Cancer is a serious health-related problem in the human body nowadays. The 2019 pandemic of coronavirus disease has developed into an unheard-of pandemic. Given the havoc wreaked by this pathogen worldwide, many countries have implemented a severe, legally enforced method of social distancing, in the form of a lockdown. Unless adequate preventive measures are taken, the cost of the pandemic and subsequent lockdown can prove to be irreparable. The obvious consequences of this lockout, such as the escalating levels of unemployment, imminent economic crisis, and extreme food scarcity faced by the sudden unemployed migrant labour population, have been widely reported. Cancer patients are a highly vulnerable group even during non-pandemic periods, often presenting late in the course of their illness, without the services required to avail recommended care. The incidence of psychological complications and emotional distress is considerably higher than in the general population, and the trauma of both the pandemic and subsequent lockdown contributes significantly to their mental trauma. This analysis is geared at solving the challenges faced by cancer patients in the face of this pandemic and subsequent lockdown, with a look at potential solutions that can be enforced.

Physical fitness is an indicator for children’s public health status. Therefore, the aim of this study was to examine the construct validity and the criterion-related validity of the German motor test (GMT) in Egyptian schoolchildren. A cross-sectional study was conducted with a total of 931 children aged 6 to 11 years (age: 9.1 ± 1.7 years) with 484 (52%) males and 447 (48%) females in grades one to five in Assiut city. The children’s physical fitness data were collected using GMT. GMT is designed to measure five health-related physical fitness components including speed, strength, coordination, endurance, and flexibility of children aged 6 to 18 years. The anthropometric data were collected based on three indicators: body height, body weight, and BMI. A confirmatory factor analysis was conducted with IBM SPSS AMOS 26.0 using full-information maximum likelihood. The results indicated an adequate fit (χ2 = 112.3, df = 20; p < 0.01; CFI = 0.956; RMSEA = 0.07). The χ2-statistic showed significant results, and the values for CFI and RMSEA showed a good fit. All loadings of the manifest variables on the first-order latent factors as well as loadings of the first-order latent factors on the second-order superordinate factor were significant. The results also showed strong construct validity in the components of conditioning abilities and moderate construct validity in the components of coordinative abilities. GMT proved to be a valid method and could be widely used on large-scale studies for health-related fitness monitoring in the Egyptian population.

Abstract Study Objectives Sleep regularity predicts many health-related outcomes. Currently, however, there is no systematic approach to measuring sleep regularity. Traditionally, metrics have assessed deviations in sleep patterns from an individual’s average. Traditional metrics include intra-individual standard deviation (StDev), Interdaily Stability (IS), and Social Jet Lag (SJL). Two metrics were recently proposed that instead measure variability between consecutive days: Composite Phase Deviation (CPD) and Sleep Regularity Index (SRI). Using large-scale simulations, we investigated the theoretical properties of these five metrics. Methods Multiple sleep-wake patterns were systematically simulated, including variability in daily sleep timing and/or duration. Average estimates and 95% confidence intervals were calculated for six scenarios that affect measurement of sleep regularity: ‘scrambling’ the order of days; daily vs. weekly variation; naps; awakenings; ‘all-nighters’; and length of study. Results SJL measured weekly but not daily changes. Scrambling did not affect StDev or IS, but did affect CPD and SRI; these metrics, therefore, measure sleep regularity on multi-day and day-to-day timescales, respectively. StDev and CPD did not capture sleep fragmentation. IS and SRI behaved similarly in response to naps and awakenings but differed markedly for all-nighters. StDev and IS required over a week of sleep-wake data for unbiased estimates, whereas CPD and SRI required larger sample sizes to detect group differences. Conclusions Deciding which sleep regularity metric is most appropriate for a given study depends on a combination of the type of data gathered, the study length and sample size, and which aspects of sleep regularity are most pertinent to the research question.

The COVID-19 pandemic and associated restrictive measures implemented may considerably affect people’s lives. This study aimed to assess the well-being of Vietnamese people after COVID-19 lockdown measures were lifted and life gradually returned to normal. An online survey was organized from 21 to 25 April 2020 among Vietnamese residents aged 18 and over. The survey was launched by the Hue University of Medicine and Pharmacy. The WHO-5 Well-Being Index (scored 0–25) was used to score participants’ well-being. A multivariate logistic regression model was used to determine the predictors of well-being. A total of 1922 responses were analyzed (mean age: 31 years; 30.5% male; 88.2% health professionals or students in the health sector). The mean well-being score was 17.35 ± 4.97. Determinants of a high well-being score (≥13) included older age, eating healthy food, practicing physical exercise, working from home, and adhering to the COVID-19 preventive measures. Female participants, persons worried about their relatives’ health, and smokers were more likely to have a low well-being score. In conclusion, after the lockdown measures were lifted, the Vietnamese have people continued to follow COVID-19 preventive measures, and most of them scored high on the well-being scale. Waiting to achieve large-scale COVID-19 vaccine coverage, promoting preventive COVID-19 measures remains important, together with strategies to guarantee the well-being of the Vietnamese people.

AbstractThe Covid-19 pandemic has led to a health crisis of a scale unprecedented in post-war Europe. In response, a large amount of healthcare resources have been redirected to Covid-19 preventive measures, for instance population-wide vaccination campaigns, large-scale SARS-CoV-2 testing, and the large-scale distribution of protective equipment (e.g., N95 respirators) to high-risk groups and hospitals and nursing homes. Despite the importance of these measures in epidemiological and economic terms, health economists and medical ethicists have been relatively silent about the ethical rationales underlying the large-scale allocation of healthcare resources to these measures. The present paper seeks to encourage this debate by demonstrating how the resource allocation to Covid-19 preventive measures can be understood through the paradigm of the Rule of Rescue, without claiming that the Rule of Rescue is the sole rationale of resource allocation in the Covid-19 pandemic.

The results of our study show that the respondent’s perception of large-scale social changes associated with the pandemic of the new coronavirus infection in the Kyrgyz Republic has a number of features. A sufficient level of awareness of the respondents about the symptoms of the disease, the ways of transmission of the virus, and measures to prevent the spread of infection are combined with an underestimation of the situation (17.2%). The majority (66.6%) of the respondents lived in Bishkek. The survey was held among 247 people, most of whom were women (57.3%) and young people (35.9±14.9 years). Every fourth participant in the study is a chronic tobacco smoker (24%). Less than half (47.3%) of the respondents were engaged in intellectual work. Among the respondents, the most common symptoms of COVID-19 were loss of taste or smell, fever, headache, muscle ache, cough, sore throat. Every third (28.4%) respondent was referred to an X-ray, CT scan. PCR and ELISA studies were carried out, respectively, by 22.5% and 10.9%.

Synthetic Pesticides

Heavy reliance on synthetic pesticides for crop protection becomes increasingly unsustainable, calling for robust alternative strategies that do not degrade the environment and vital ecosystem services. There exist numerous reports of successful disease control using various microbes in small-scale trials. However, their inconsistent efficacy has hampered large-scale applications. An enhanced understanding of how beneficial microbes interact with plants, other microbes, and the environment and which factors affect their efficacy of disease control is crucial to deploy microbial allies as effective and reliable pesticide alternatives. Diverse metabolites produced by plants and microbes participate in pathogenesis and defense, regulate the growth and development of themselves and neighboring organisms, help maintain cellular homeostasis under varied environmental conditions, and affect the assembly and activity of plant and soil microbiomes. However, research on the metabolites associated with plant growth/health-related processes, except antibiotics, has not received adequate attention. This review highlights several classes of metabolites known or suspected to affect plant health, focusing on those associated with biocontrol and belowground plant-microbe and microbe-microbe interactions. The review also presents how new insights anticipated from systematically exploring the diversity and mechanism of action of bioactive metabolites can be harnessed to develop novel crop protection strategies.

New Treatment

The National Institute of Mental Health (NIMH) has embarked upon a new venture—effectiveness trials, large-scale trials to test more than one treatment option for individuals affected with diverse major mental disorders. The launch follows a recent report by the NIMH National Advisory Mental Health Council, which emphasized the failure within routine clinical care to widely implement findings of randomized, controlled efficacy trials (RCTs)—perhaps, in part, because of reduced generalizability that leaves real-world application unclear.Efficacy trials do not answer a number of key clinical questions, including: (1) Are the treatments as effective and safe in representative patient groups? (2) How does the new treatment fit within the treatment armamentarium? (3) When should the new treatment be combined with existing interventions? (4) What are the long-term benefits? (5) Do treatments differ regarding their effectiveness in patients with comorbid general medical or psychiatric disorders? (6) How do these newer treatments affect costs of routine care? Effectiveness trials can address a number of these issues and incorporate a broad range of outcomes, including symptom reduction, day-to-day function, side effect burden, and patient satisfaction.With a major aim of effectiveness trials being increased generalizability, selection of participants is crucial. Since symptomatic volunteers, who are typically used in efficacy RCTs for major depressive disorder, may be more responsive to either the nonspecific aspects of treatment or to the treatment itself than self-declared patients with concomitant comorbidities, setting minimal exclusion criteria, recruiting large samples of patients from representative practices, and excluding symptomatic volunteers assures that patients are representative, while protecting the internal validity of the trial. In addition, treatments must be reasonably well delivered so that outcomes can be attributed to the treatment per se and not to improper implementation of an otherwise effective treatment. Frequent clinic visits, patient/family educational efforts, universal access to all protocol recommended treatments (including psychotherapy), and adequate provider compensation can ensure that treatments are reasonably well delivered.
