Umifenovir in COVID-19 therapy: a systematic review and meta-analysis.

SARS-CoV-2 has infected more than 600 million people worldwide over the last 2.5 years. So far, there efficacy of many antiviral drugs against COVID-19 has been evaluated only in small studies conducted in different countries. Objective. To assess the efficacy of umifenovir in patients with COVID-19. Materials and methods. We performed systematic search of publications in the PubMed and Google Scholar databases. Sixteen studies with a total of 1,843 patients were included in the analysis. The following endpoints were evaluated: frequencies of negative PCR test on days 7 and 14;mortality in patients with mild, moderate, and severe disease;and frequency of fever resolution on day 7. Results. We found that patients receiving umifenovir demonstrated a significantly higher frequency of negative PCR test on day 7 than patients who received no causal therapy or other antiviral drugs (odds ratio (OR) 1.69, 95% confidence interval (CI): 1.09-2.62, p = 0.02, I2 = 13%). This difference was even more significant among patients with mild to moderate COVID-19 (OR: 2.03, 95% CI: 1.24-3.32, p = 0.005, I2 = 0%), as well as on day 14 (OR: 2.02, 95% CI: 1.35-3.94, p = 0.0007, I2 = 50%). We also observed a reduced risk of death in the studies that included only patients with mild and moderate disease (JR: 0.53, 95% CI: 0.33-0.83, p = 0.006, I2 = 0). Umifenovir therapy did not affect the frequency of fever resolution by day 7 (OR: 0.87, 95% CI: 0.49-1.56, p = 0.64, I2 = 0%). Conclusion. Umifenovir significantly accelerated virus elimination by days 7 and 14 among patients with mild to moderate COVID-19. Umifenovir also reduced the risk of death compared to other antiviral drugs.Copyright © 2022, Dynasty Publishing House. All rights reserved.

Influence of environmental and demographic factors on the transmission and mortality rate of COVID19 in India

COVID-2019 has been declared a Public Health Emergency of International Concern (PHEIC) by the World Health Organization due to the global spread of 2019-nCOV at an exponential rate (WHO). Scientists have hypothesized the reduction in transmission rate at warm and humid environment whereas facilitate rapid transmission at cold and dry environment. Hence in this work, we examine the combined impact of environmental and demographic factors along with the implementation of lockdown by the Government of India on the transmission rate of 2019-nCoV. Our analyses indicated a lower mortality rate in spite of higher population density in India compared to other countries and lower exponential growth factor after lockdown compared to before lockdown. The containment of transmission and mortality rate may be attributed to the favorable environment and median population age, respectively. Even though, to significantly reduce the outbreak, individuals, the media, and healthcare organizations are necessary to work together. © 2023 Author(s).

The macroeconomic impact of the pandemic on the economies of African countries is explored with a focus on sectors such as merchandise trade, agriculture, tourism, and oil with current data. The analysis indicates serious gaps in access to adequate public health and how this has negative implications for economic stability. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

Study of body composition analysis in the view of obesity prognosis

Chronic overweight is characterized by significant elevations in abdominal fat as well as changes in the composition of fat free mass, particularly total body fluids and its interstitial compartment. The applied in the real restrictions placed by morbid obesity, as well as changes in body content from those of healthy weight, provide enormous hurdles to fat percentage assessment. This research concentrates on some of the research and practice challenges connected with using popular fat percentage measures, and it finds available evidence on suitable approaches for use in extremely obese people. There is already little scientific literature on which body composition measures may be utilised confidently in very obese people. A typical 3 model that combines readings of body mass by air - assisted plethysmography and total body liquid by bio-electrical impedance could provide metrics of percentage body fat in the extremely obese that are significant compared to a conventional, technically skilled 3 storage area prototype that requires infrastructure including such isotopic ratios mass spectrometry as well as important technological knowledge. This study focuses on a few fundamental issues that investigators and physicians confront when doing anthropometric studies on highly obese individuals. A 3 basic framework that is efficient and simple to implement shows potential for usage in this community. Nonetheless, more study on this and other suitable techniques of fat percentage measurement in a broad sample of extremely overweight adults is required. © 2023 Author(s).

Epidemiological and clinics characteristics of 414 cases of oral lesions and sensorial functions of COVID-19 in Brazil

Introduction: Several studies have evaluated the occurrence of oral lesions and changes in sensory functions in patients positive for COVID-19. Objective(s): To evaluate the manifestations of COVID-19, emphasizing olfactory and gustatory changes, xerostomia, and oral lesions. Material(s) and Method(s): A cross-sectional and observational study was conducted. Approved by the Institutional Ethics Committee (#46151121.6.0000.5141). All patients were diagnosed by reverse transcription-polymerase chain reaction assay (RT-PCR) and considered to have mild symptoms, according to the latest WHO joint report. The patients were evaluated at a reference Service for COVID-19 in Minas Gerais, Brazil. The oral cavity was evaluated for each patient on the second and seventh days. Result(s): A total of 414 patients older than 18 years were evaluated. One hundred thirty-nine presented at least one of the studied conditions, oral lesions (19.08%) were the most frequently observed, followed by gustatory disorders (18.11%), xerostomia (14.25%), and olfactory dysfunction (14%). Among the oral lesions, there were various anatomical locations and clinical presentations. The occurrence involving lips and tongue represented 49 oral lesions, the most prevalent being, respectively, ulcerations (n=51), candidiasis (n=8), and erythema or red plaques (n=7). Fifty patients died. Conclusion(s): This study represents, to date, the largest case series of oral lesions in Brazilian patients with COVID-19, and oral alterations were observed in an expressive percentage of patients with COVID-19. However, it cannot be concluded that SARS-CoV-2 directly causes them.

Risk Factors and Clinical Characteristics of Acute Kidney Injury in Patients with COVID-19: A Systematic Review and Meta-Analysis.

Acute kidney injury (AKI) is associated with a worse prognosis in coronavirus disease 2019 (COVID-19) patients. Identification of AKI, particularly in COVID-19 patients, is important for improving patients' management. The study aims to assess risk factors and comorbidities of AKI in COVID-19 patients. We systematically searched PubMed and DOAJ databases for relevant studies involving confirmed COVID-19 patients with data on risk factors and comorbidities of AKI. The risk factors and comorbidities were compared between AKI and non-AKI patients. A total of 30 studies involving 22385 confirmed COVID-19 patients were included. Male (OR: 1.74 (1.47, 2.05)), diabetes (OR: 1.65 (1.54, 1.76)), hypertension (OR: 1.82 (1.12, 2.95)), ischemic cardiac disease (OR: 1.70 (1.48, 1.95)), heart failure (OR: 2.29 (2.01, 2.59)), chronic kidney disease (CKD) (OR: 3.24 (2.20, 4.79)), chronic obstructive pulmonary disease (COPD) (OR: 1.86 (1.35, 2.57)), peripheral vascular disease (OR: 2.34 (1.20, 4.56)), and history of nonsteroidal anti-inflammatory drugs (NSAID) (OR: 1.59 (1.29, 1.98)) were independent risk factors associated with COVID-19 patients with AKI. Patients with AKI presented with proteinuria (OR: 3.31 (2.59, 4.23)), hematuria (OR: 3.25 (2.59, 4.08)), and invasive mechanical ventilation (OR: 13.88 (8.23, 23.40)). For COVID-19 patients, male gender, diabetes, hypertension, ischemic cardiac disease, heart failure, CKD, COPD, peripheral vascular disease, and history of use of NSAIDs are associated with a higher risk of AKI.

Content and Sentiment Analysis of The New York Times Coronavirus (2019-nCOV) Articles with Natural Language Processing (NLP) and Leximancer

The purpose of this study was to prove the use of content and sentiment analysis to understand public discourse on Nytimes.com around the coronavirus (2019-nCOV) pandemic. We examined the pandemic discourses in the article contents, news, expert opinions, and statements of official institutions with natural language processing methods. We analyzed how the mainstream media (Nytimes.com) sets the community agenda. As a method, the textual data for the research were collected with the Orange3 software text-mining tool via the Nytimes.com API, and content analysis was conducted with Leximancer software. The research data were divided into three categories (first, mid, and last) based on the date ranges determined during the pandemic. Using Leximancer concept maps tools, we explained concepts and their relationships by visualizing them to show pandemic discourse. We used VADER sentiment analysis to analyze the pandemic discourse. The results gave us the distance and proximity positions of themes related to Nytimes.com pandemic discourse, revealed according to their conceptual definitions. Additionally, we compared the performance of six machine learning algorithms on the task of text classification. Considering the findings, it is possible to conclude that in Nytimes.com (2019-nCOV) discourse, some concepts have changed on a regular basis while others have remained constant. The pandemic discourse focused on specific concepts that were seen to guide human behavior and presented content that may cause anxiety to readers of Nytimes.com. The results of the sentiment analysis supported these findings. Another result was that the findings showed us that the contents of the coronavirus (2019-nCOV) articles supported official policies. It can be concluded that regarding the coronavirus (2019-nCOV), which has caused profound societal changes and has results such as death, restrictions, and mask use, the discourse did not go beyond a total of 15 main themes and about 100 concepts. The content analysis of Nytimes.com reveals that it has behavioral effects, such as causing fear and anxiety in people. Considering the media dependency of society, this result is important. It can be said that the agenda-setting of society does not go beyond the traditional discourse due to the tendency of individuals to use newspapers and news websites to obtain information.

Adherence to online psychotherapy during the COVID-19: a scoping review / Adesão à psicoterapia on-line durante a COVID-19: uma revisão de escopo / Adherencia a la psicoterapia online durante el COVID-19: una revisión del alcance

Evidence suggests that changes in online psychotherapy adherence factors occurred during the COVID-19 pandemic. Thus, this study aimed to review the perception of patients and psychotherapists regarding factors associated with adherence to online psychotherapy during the pandemic. Thus, 18 articles remained for analysis after searches in five databases and 25 factors associated with adherence to online psychotherapy were identified. The main factors for psychotherapists were confidence in professional skills and connection stability. For the patients, basic informatics skills and finding an adequate setting to participate in sessions. Furthermore, the factors fear of contagion, tiredness and the impossibility of face-to-face meetings emerged during the pandemic. Modifications of factors associated with pre-pandemic adherence were identified and strategies to overcome barriers related to online sessions were presented and discussed. The pandemic has increased adherence to online psychotherapy, although not everyone intends to follow this modality in the post-pandemic. (AU)

Global prevalence of self-harm during the COVID-19 pandemic: a systematic review and meta-analysis.

BACKGROUND: COVID-19 and its transmission mitigation measures have caused widespread mental health problems. Previous studies have suggested that psychological, economic, behavioral, and psychosocial problems associated with the COVID-19 pandemic may lead to a rise in self-harm. However, little is known about the prevalence of self-harm worldwide during COVID-19. Therefore, a quantitative synthesis is needed to reach an overall conclusion regarding the prevalence of self-harm during the pandemic. METHODS: By using permutations of COVID-19, self-harm or relevant search terms, we searched the following electronic databases from November 2019 to January 2022: Web of Science, PubMed, MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews, China National Knowledge Infrastructure (CNKI), Wanfang Database and systematically reviewed the evidence according to MOOSE guidelines. We employed Cochran's chi-squared test (Cochran's Q), I2test and subgroup analysis to assess and address the heterogeneity. Sensitivity analysis was conducted by eliminating each included study individually and then combining the effects. RESULTS: Sixteen studies that met the inclusion and exclusion criteria were identified, with sample sizes ranging from 228 to 49,227. The methodological quality of the included studies was mostly at the medium level. By using a random effect model, the pooled prevalence of self-harm was 15.8% (95% CI 13.3-18.3). Based on subgroup analysis, the following characteristics of the included studies were more likely to have a higher prevalence of self-harm: studies conducted in Asia or prior to July 2020, cross-sectional studies, samples recruited in hospitals or schools, adolescents, females, the purpose of self-harm (NSSI), mental symptoms and restriction experiences. CONCLUSIONS: We provided the first meta-analytic estimated prevalence of self-harm based on a large sample from different countries and populations. The prevalence of self-harm during COVID-19 was not encouraging and requires attention and intervention. Further high-quality and prospective research are needed in order to determine the prevalence of self-harm with greater accuracy because to the clear heterogeneity across the included studies. In addition, this study also provides new directions for future research, including the identification of high-risk groups for self-harm, the formulation and implementation of prevention and intervention programs, and the long-term impact of COVID-19 on self-harm.

Early laboratory hematological parameters associated with COVID-19 mortality in an Amazonian population of Peru

COVID-19 has a significant impact on the hematopoietic system and hemostasis. Leukocytosis, lymphopenia, and thrombocytopenia are associated with increased severity and even death in COVID-19 cases. Objective: The aim is to examine the laboratory results of COVID-19 patients from a hospital in the Peruvian Amazon and their clinical prognosis. Material and Methods: An analytical cross-sectional study was carried out whose purpose was to identify the laboratory tests of patients with COVID-19 and mortality in a hospital in Ucayali, Peru during the period from March 13 to May 9, 2020, selecting a total of 127 with Covid-19. Mean and the standard deviation was described for age, leukocytes, neutrophils, platelets, RDW-SD;median and interquartile range for the variables lymphocyte, RN / L, fibrinogen, CRP, D-dimer, DHL, hematocrit, monocytes, eosinophils. Results: No differences were observed in this population regarding death and sex (OR: 1.31;95% CI 0.92 to 1.87), however, it was observed that, for each one-year increase, the probability of death increased by 4% (PR: 1.04, 95% CI 1.03 to 1.05). The IRR (Incidence Risk Ratio) analysis for the numerical variables showed results strongly associated with hematological values such as Leukocytes (scaled by 2500 units) ( IRR: 1.08, 95% CI 1.03 to 1.13), neutrophils (scaled by 2500 units) (IRR: 1.08;95% CI 1.03 to 1.13), on the contrary, it is observed that the increase of 1000 units in lymphocytes, the probability of dying decreased by 48% (IRR: 0.52;95% CI 0.38 to 071). Conclusions: Parameters such as leukocytes,neutrophils and D-dimer were statistically much higher in patients who died.

Certain efficient techniques to solve the unreported cases of 2019-nCoV epidemic model

One of the furthermost intimidations that the death faced after the second World War is 2019-nCoV epidemic and most crucial large-scale health disaster of this century. We devote the current work to discuss the epidemic prediction for the epidemic model created for 2019-nCoV in Wuhan, China by certain approximate analytical methods such as differential transform method and variational iteration method. Further, we recognize unreported cases in numbers and the parameters of model are due to reported case data. For the considered system demonstrating the model of coronavirus, the series solution is conventional in the structure of the differential transform method. The obtained solutions are discussed in figures which show the performance of considered model. The results show that the used schemes are definite and trouble-free to execution for the system of nonlinear ODEs. The solutions exposed that the both schemes are in total agreement, correct and well-organized for solving systems of nonlinear differential equations.

Opinions of Infectious Diseases and Clinical Microbiology Physicians on Hospital Pandemic Management and Factors Influencing Reading the Pandemic Influenza National Preparedness Plan

Introduction: Infectious Diseases and Clinical Microbiology (IDCM) physicians have critical importance in terms of pandemic management in hospitals. There are recommendations for hospitals in the national pandemic preparedness plan, which was developed to limit the damage during pandemic periods. With this study, it was aimed to determine the reading status of IDCM physicians of the pandemic plan and the factors affecting it, and to learn their views on the application of the headings in the plan. Materials and Methods: For this descriptive study, the opinions of physicians were collected with an electronic questionnaire for the periods of June 2020 and January 2021. Statistical analyses were conducted to determine the associated factors of physicians' reading of the pandemic plan. Results: Of the 169 physicians participating in the study, 62.7% were women, with a mean age of 43.1 +/- 9.9 years, and nearly two-thirds of the physicians were working in a tertiary hospital. More than 70% of physicians read the pandemic preparedness plan. The rate of reading of the pandemic plan increased with the physician's time spent in IDCM practice [odds ratio (OR)=1.08, 95% confidence interval (CI)=1.01-1.16, p=0.037], and previous Coronavirus disease-2019 (COVID-19) experience (OR=3.10, 95% CI=1.00-9.58, p=0.050), and it decreased with the hand hygiene compliance of healthcare professional (OR=0.27, 95% CI=0.11-0.68, p=0.006) and the number of IDCM physicians working in the physician's hospital (OR=0.97, 95% CI=0.94-0.99, p=0.016). Conclusion: Physicians' reading status of the national pandemic preparedness plan did not differ significantly between the periods. As the time spent in IDCM practice and their pandemic experience before COVID-19 increased, the status of reading the pandemic plan increased. As the compliance with hand hygiene among the health professionals working in the physicians' hospital and the number of IDCM physicians increased it decreased. Attention should be paid to the introduction of the pandemic plan to physicians with professional inexperience and no pandemic experience.
