Survey on knowledge and behaviors related to covid–19 and plague prevention and control in qinghai

Objective To understand the knowledge of COVID-19 and plague prevention and control in Qinghai Province, so as to carry out targeted health education and improve people's ability to prevent and control COVID–19, plague and other publichealth emergencies. Methods Six counties were randomly selected from three cities (states) by two-stage sampling. A self- designed questionnaire was randomly distributed to the public to investigate the awareness and behavior of COVID-19 and plague prevention and control. The Chinese version of Epidate was used for database construction and data entry. After checking and verifying, the data was exported as an Excel file and analyzed by SPSS 21.0 software. Results Accordign to the recovered questionnaires, the passing rate of knowledge of COVID-19 prevention and control was 78.46%, and the average score was (75. 82±16.43). The passing rate of plague prevention and control knowledge was 91.89%, and the average score was (86.46±15.94). The survey area, occupation category, gender and education level affected the knowledge of COVID-19 prevention and control. The average score was statistically significant (P<0.05). The survey area, occupation category, age and education level affected the knowledge of plague prevention and control, and the average score was statistically significant (P<0. 05). Conclusion People in Qinghai have poor knowledge of COVID - 19 prevention and control, but have good knowledge of plague prevention and control. Health education and health promotion activities on COVID - 19 and plague prevention and control should be increased in the future. © 2023, Editorial Department of Medical Pest Control.

Leveraging Bluetooth Low-Energy Technology to Improve Contact Tracing in Healthcare Settings during the COVID-19 Pandemic

Background. COVID-19 rapidly evolved into a global pandemic. Contact tracing with isolation and quarantine contribute to epidemic control but they are time consuming, costly and may be incomplete. We set out to assess the usability and performance characteristics of Bluetooth Low-Energy (BLE) wireless technology for indoor localization applied to contact tracing in healthcare settings. Methods. Consented healthcare workers (HCW) from 2 designated COVID-19 wards (one intensive care unit (ICU) and one medical ward) were equipped with coinsized BLE- emitting beacons. The signal was captured by small embedded computers (anchors) placed at designated locations, time-stamped and transmitted to an edge server via secure Wi-Fi where data were stored and real time contact algorithms were run (Fig.1). We developed experiments mimicking clinical scenarios and tested indoor localization during observed clinical activity for 6 months. We constructed our algorithms based on room structure (e.g. open spaces vs computer rooms) and activity characteristics (e.g. rounding in a large group vs 2 healthcare workers sitting together). We used 1) radio fingerprint localization where an initial virtual radio map was developed, 2) semantic localization which carries additional information such as proximity to a computer to define indirect transmission via fomites, and 3) clustering contact tracing to identify individuals rounding together. Close contact was defined as per the CDC guidelines. Fig. 1 System configuration Results. Consent rate was 43.3% with 187 HCW enrolled in the study. Consent rate was higher in the ICU and among attendings. All participants were compliant with wearing the beacons for the duration of the study. The performance characteristics for contact tracing using fingerprinting methods were AUROC 0.93, AUPRC 0.96, sensitivity 0.9, specificity 0.77 with F1 score of 0.89 and overall accuracy of 0.85. The clustering contact tracing registered a sensitivity of 0.86, specificity 0.89, F1 score 0.91 and accuracy 0.87. Computation time necessary to generate a list of close contacts as per specified criteria was less than 30 minutes. Conclusion. We have developed and tested a reliable and accurate, low-cost and easily deployable system based on BLE technology to improve contact tracing among healthcare workers.

Application of photobiomodulation therapy in acupuncture

Photobiomodulation (PBM) therapy is a therapeutic method that can produce a range of physiological effects in cells and tissues using certain wavelengths. The reparative benefits of PBM therapy include wound healing, bone regeneration, pain reduction, and the mitigation of inflammation. Advances in the development of laser instruments, including the use of high-intensity lasers in physiotherapy, have recently led to controllable photothermal and photomechanical treatments that enable therapeutic effects to be obtained without damaging tissue. The combination of PBM therapy with acupuncture may provide new perspectives for investigating the underlying therapeutic mechanisms of acupuncture and promote its widespread application.

Role of Vaccination in the COVID-19 Nationwide Cohort (N3C) of Solid Organ Transplant Recipients

Purpose: Immunosuppressed solid organ transplant (SOT) patients have been repeatedly challenged in the COVID-19 pandemic with significant morbidities and mortality following infection and a suppressed immune response to vaccination. The aim of this study was to assess the impact on COVID-19 morbidity and mortality in the presence and absence of vaccination. Method(s): We studied adult (>18 years) patients from across the United States identified using the National COVID Cohort Collaborative (N3C) Enclave from Dec 10, 2020-Oct 12, 2021. Using multivariable logistic regression, we determined the odds of developing COVID-19 infection in the 6 months after full vaccination (defined as a breakthrough (BT) infection) in SOT recipients relative to nonimmunosuppressed (non-IS) patients. In SOT patients with BT COVID-19 infection, we then used multivariable logistic regression to determine the association of full and partial vaccination status with major adverse cardiac events, mortality, and additional secondary outcomes in the 90 days following COVID-19 diagnosis relative to unvaccinated/unconfirmed vaccination status SOT recipients). Result(s): Over the study period, 16,075 SOT patients were diagnosed with COVID-19 (515 were partially vaccinated, and 1,868 were fully vaccinated). Relative to non- IS, SOT was associated with an increased odds of BT COVID-19 infection in the 6 months post vaccine, that varied by organ type (i.e. OR 1.97, 95% CI 1.75-2.25 for kidney;OR 2.30, 95% CI 1.70-3.06 for lung), Table 1. In SOT patients who experienced BT COVID-19, full vaccination was associated with a small reduction in adverse outcomes relative to unvaccinated/unconfirmed vaccination status (OR 0.91, 95% CI 0.89-0.93 for MARCE;OR 0.92, 95% CI 0.90-0.93 for death;OR 0.90, 95% CI 0.88-0.92 for hospitalization), Table 2. Conclusion(s): SOT patients are at a ~2-fold increased odds of BT COVID-19 infection after vaccination compared with non-IS patients. Vaccination in SOT patients, regardless of product, has a small but significant reduction in the risk of adverse outcomes after a diagnosis of COVID-19, however SOT recipients remain at high risk and should continue to use caution even after vaccination.

Impact of oil prices and stock returns: Evidence of oil and gas mining companies in indonesia during the COVID-19 period

This study points to analyze the determinants of stock return revelation in oil and gas mining division companies recorded on the Indonesia Stock Trade-in 2019-2021 amid the Covid-19 emergency. The think about utilized the Eviews Program as information preparing and the irregular impact relapse show was chosen to look at the relationship between outside and inside markers as autonomous factors counting Current Ratio, debt to equity ratio, total asset turnover, return on assets, oil price, an exchange rate, institutional ownership. The comes about appeared that the current proportion, obligation to value ratio and add up to resource turnover did not influence stock returns. Return on resources, exchange rates, and institutional ownership have a negative and significant impact on stock returns, while oil prices have a positive and widespread effect on stock returns. © 2021, Econjournals.

COVID-19 in solid organ transplantation (SOT): Results of the national covid cohort collaborative (N3C)

Purpose: SARS-CoV-2 infection has resulted in significant mortality in solid organ transplant (SOT) recipients based on reports from single centers or voluntary registries. The N3C Enclave was developed to facilitate analysis of patient-level data across the US for multiple conditions, consisting of weekly electronic medical record (EMR) data extraction and transmission into a federally secured platform. Herein is our report of the largest cohort of US COVID-19 positive SOT patients to date. Methods: We identified a cohort of SOT recipients who received a positive or negative COVID-19 test (COVID+ and COVID-, respectively) between 01/01/2020 and 11/23/2020. In COVID+ SOT, we evaluated outcomes including requirement for hospitalization, major adverse cardiac events (MACE), and graft rejection and failure occurring until study end. Significant differences between COVID+ and COVID- patients were identified using t-test and chi-square testing, as indicated. Results: 34 sites account for 2.15 million patients in the Enclave, of whom 292,226 are COVID+. We identified 19,031 SOT patients, of whom 2,183 were COVID+ (11.5%) with a median follow-up time of 119 days. Demographics are shown in Figure 1. Compared to COVID- SOT patients, COVID+ SOT patients were more likely to have a kidney transplant and be non-white or Hispanic. Hypertension, diabetes, coronary artery disease and chronic kidney disease were common comorbidities in all SOT, but significantly more common in those who were COVID+. Of COVID+ SOT, 51.8% required hospital admission for a median of 1 days (range 0-114). Following COVID diagnosis, 13.7% of COVID+ SOT patients experienced MACE, 3.8% had graft rejection and 3.4% had graft loss over the study period. Conclusions: In the largest US cohort of COVID+ SOT recipients to date, we identify patient factors associated with the diagnosis of COVID-19 and outcomes following infection including a relatively high incidence of MACE. This is an evolving dataset and provides novel opportunities for analyses of COVID in SOT recipients on a granular level.

Effects of air-conditioning systems in the public areas of hospitals: A scoping review

Almost all hospitals are equipped with air-conditioning systems to provide a comfortable environment for patients and staff. However, the accumulation of dust and moisture within these systems increases the risk of transmission of microbes and have on occasion been associated with outbreaks of infection. Nevertheless, the impact of air-conditioning on the transmission of microorganisms leading to infection remains largely uncertain. We conducted a scoping review to screen systematically the evidence for such an association in the face of the COVID-19 epidemic. PubMed, Embase, and Web of Science databases were explored for relevant studies addressing microbial contamination of the air, their transmission, and association with infectious diseases. The review process yielded 21 publications, 17 of which were cross-sectional studies, three were cohort studies, and one case-control study. Our analysis showed that, compared with naturally ventilated areas, microbial loads were significantly lower in air-conditioned areas, but the incidence of infections increased if not properly managed. The use of high-efficiency particulate air (HEPA) filtration not only decreased transmission of airborne bioaerosols and various microorganisms, but also reduced the risk of infections. By contrast, contaminated air-conditioning systems in hospital rooms were associated with a higher risk of patient infection. Cleaning and maintenance of such systems to recommended standards should be performed regularly and where appropriate, the installation of HEPA filters can effectively mitigate microbial contamination in the public areas of hospitals.

INFORMATION ACCESSIBILITY FOR PUBLIC HEALTH EMERGENCIES-A CASE STUDY OF INFORMATION ACCESSIBILITY DURING THE NEW CORONAVIRUS OUTBREAK

Barrier-free information construction has not been included in the information disclosure system for public emergencies in China This makes it difficult for obstacle groups to obtain government information timely. By contrast, social forces, sign language videos and online accessible mini programs all give quick responds, which to some extent, bridge the information gap during the pandemic. This phenomenon is caused by the insufficient construction of information accessibility within the legal system, and the lack of popularization of accessibility concepts. The corresponding departments should improve the legal system of information accessibility by incorporating it into the information disclosure system for public emergencies in China This will speed up the construction of modern public cultural service systems, promote the development of TV sign language hosting, and improve awareness of accessibility in science and technology to promote the design standards and principles of network accessibility and improve the dissemination of barrier-five information, hence meeting the information needs of barrier-free groups for major public emergencies.
