: The novel Coronavirus (SARS-CoV-2) that has emerged and spread throughout the world causing CoV disease-19 (COVID-19) has since its discovery affected not only humans and animals but also the environment. Because of the highly infectious nature of the virus, and the respiratory aerosol transmission route, face masks and personal protective equipment have become mandatory for public and healthcare workers, respectively. Also, the complex nature of the pathogenicity of the virus, wherein, it has been associated with mild, moderate, and severe life-threatening infections, has warranted increased laboratory testing and placing the infected people in isolation and under constant observation in quarantine centers or at dedicated hospitals. Some infected people, who are generally healthy, and do not show symptoms have been placed in home quarantines. At this juncture, there has been increased amount of biomedical waste (BMW), and infectious general waste along with plastic disposable recyclable and non-recyclable waste. The increased BMW along with the potentially hazardous plastic waste collection, segregation, transport, and disposal has assumed increased significance during the ongoing pandemic. Therefore, this review attempts to investigate the current scenario of BMW management and strategies to minimize BMW and prevent potential environmental pollution.

SARS-COV2 virus causes Coronavirus disease (COVID-19) and represents the causative agent of a potentially fatal disease that is of great global public health concern. The novel coronavirus (2019) was discovered in 2019 in Wuhan, the market of the wet animal, China with viral pneumonia cases and is life-threatening. Today, WHO announces COVID-19 outbreak as a pandemic. COVID-19 is likely to be zoonotic. It is transmitted from bats as intermediary animals to human. Also, the virus is transmitted from human to human who is in close contact with others. The computerized tomographic chest scan is usually abnormal even in those with no symptoms or mild disease. Treatment is nearly supportive; the role of antiviral agents is yet to be established. The SARS-COV2 virus spreads faster than its two ancestors, the SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV), but has lower fatality. In this article, we aimed to summarize the transmission, symptoms, pathogenesis, diagnosis, treatment, and vaccine to control the spread of this fatal disease.

Objective: We aimed to conduct a comparative analysis of the psychological stress experienced by healthcare workers, frontline workers, and the general public and to assess the factors associated with psychological stress in each of these groups.Methods: We conducted an online survey targeting healthcare workers, frontline workers, and the general public. Psychological stress was assessed with the revised impact of event scale (IES-R). Univariable and multivariable logistic regression analyses were conducted.Results: We surveyed 1,336 participants (64.6% female; mean age, 36.6). The occupation group distribution of respondents was 50.7% healthcare workers, 27.2% frontline workers, and 22.1% general public. The healthcare (23.6 ± 15.8) and frontline (23.6 ± 17.8) workers had higher IES-R scores than the general public (15.3 ± 10.6; p < 0.01). Poor health perception and perception of infection avoidance were associated with psychological stress in the healthcare and frontline workers, but not in the general public.Conclusion: Both healthcare and frontline workers are suffering elevated psychological stress, compared to the general public, and this elevated stress may be related especially to their perceptions of their own health and infection risk. Interventions addressing these factors should be developed to alleviate psychological stress in these populations, and thus reduce their risk of mental illness pathogenesis.

Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emergent pathogen responsible for the coronavirus disease 2019 (COVID-19). Since its emergence, the novel coronavirus has rapidly achieved pandemic proportions causing remarkably increased morbidity and mortality around the world. A hypercoagulability state has been reported as a major pathologic event in COVID-19, and thromboembolic complications listed among life-threatening complications of the disease. Platelets are chief effector cells of hemostasis and pathological thrombosis. However, the participation of platelets in the pathogenesis of COVID-19 remains elusive. This report demonstrates that increased platelet activation and platelet-monocyte aggregate formation are observed in severe COVID-19 patients, but not in patients presenting mild COVID-19 syndrome. In addition, exposure to plasma from severe COVID-19 patients increased the activation of control platelets ex vivo. In our cohort of COVID-19 patients admitted to the intensive care unit, platelet-monocyte interaction was strongly associated with tissue factor (TF) expression by the monocytes. Platelet activation and monocyte TF expression were associated with markers of coagulation exacerbation as fibrinogen and D-dimers, and were increased in patients requiring invasive mechanical ventilation or patients who evolved with in-hospital mortality. Finally, platelets from severe COVID-19 patients were able to induce TF expression ex vivo in monocytes from healthy volunteers, a phenomenon that was inhibited by platelet P-selectin neutralization or integrin αIIb/β3 blocking with the aggregation inhibitor abciximab. Altogether, these data shed light on new pathological mechanisms involving platelet activation and platelet-dependent monocyte TF expression, which were associated with COVID-19 severity and mortality.

The outbreak of viral pneumonia caused by the novel coronavirus SARS-CoV-2 that began in December 2019 caused high mortality. It has been suggested that the main protease (Mpro) of SARS-CoV-2 may be an important target to discover pharmaceutical compounds for the therapy of this life-threatening disease. Remdesivir, ritonavir and chloroquine have all been reported to play a role in suppressing SARS-CoV-2. Here, we applied a molecular docking method to study the binding stability of these drugs with SARS-CoV-2 Mpro. It appeared that the ligand–protein binding stability of the alliin and SARS-CoV-2 Mpro complex was better than others. The results suggested that alliin may serve as a good candidate as an inhibitor of SARS-CoV-2 Mpro. Therefore, the present research may provide some meaningful guidance for the prevention and treatment of SARS-CoV-2.

Background: This study was to investigate the cancellation rate and trend of orthopedic surgeries during the novel coronavirus disease 2019 (COVID-19) pandemic. Moreover, we assessed the psychologic status of orthopedic healthcare workers, and investigated the details of the preventive surgeries underwent in COVID-19-positive patients.Methods: For 3 months after January 20, 2020, cancellation rates of elective surgeries were investigated, and the number of elective surgeries conducted in the same period over the last two years was compared. Four different questionnaires were used to investigate psychologic status among the orthopedic health care workers. We compared the outcomes according to occupation (physician or nurse), and type of work (faculty staff or resident physician). Outcomes according to occupation and type of work were compared. Preventive surgeries underwent in patients who could not wait for the results of the COVID-19 diagnosis were investigated.Results: Spine and hip surgery had relatively lower cancellation rates, and elective surgeries were significantly reduced. During the initial pandemic, the cancellation rate of orthopedic elective surgeries was significantly higher than in the same period of the previous year and was different for each subdivision depending on the degree of pain or disability. The psychological outcomes were within the normal range and there were no significant differences between groups. After preventive surgery, all medical staff involved in the operation tested negative.Conclusion: During the COVID-19 pandemic, the cancellation rate of orthopedic elective surgeries was significantly higher than in the same period of the previous year. Orthopedic health care workers did not seem to have significant psychological distress. As a result of the preventive surgery in specialized facilities, all the medical staff who participated in the operation tested negative.

Abstract Background: The severe respiratory syndrome caused by the novel coronavirus (SARS CoV 2) has caused world-wide pressure on the healthcare workers attempting to treat millions of individuals ill with COVID-19, in addition to their regular duties. Aims: examine the use of psychiatric leave by Argentinian healthcare workers during the COVID-19 pandemic; explore differences by gender. Methods: analysis of “excess of psychiatric sick leave” in health workers at a municipal level for Buenos Aires, January- October 2020. We used historical cases of psychiatric sick leave (2015-2019) and those requested in 2020. The differences between gender were determined using difference in proportions among groups. Results: The excess of psychiatric sick leave in 2020 compared to historical data was 161.90%. The difference in proportion per sex showed a significant 59.34% towards female. Conclusions: healthcare workers in the Argentinian municipality of Vicente Lopez used significantly higher number of psychiatric sick leaves during pandemic. The higher rates of psychiatric sick leave used by female replicate findings of higher rates of psychological symptoms in female healthcare workers.

Background: The novel Coronavirus (COVID-19) outbreak that began in Wuhan, China rapidly became a public health concern and a challenge for healthcare systems globally.  In the wake of the first confirmed case in The Gambia, concerns were raised in some quarters about the health system's preparedness to handle the outbreak. Therefore, we aimed to assess health personnel's knowledge and preparedness in fighting the COVID-19 outbreak in The Gambia. Methods: A cross-sectional survey was conducted using self-administered questionnaires distributed online through social media. Descriptive, bivariate, and binary logistic analyses were done using SPSS Version 22. Results: We obtained 333 valid responses. Most participants reported that their health facility has some form of preparedness; however, only a small proportion reported enough PPEs in the health facility. About half (50.5%) showed good knowledge of COVID-19. There was a statistically significant difference among the professions regarding their reaction if they were found positive of COVID-19 (p=0.006). There was a significant association between health professions [other professions (Odds ratio [OR]=0.2, 95% Confidence interval [CI]:0.04–0 .9; p=0.038)] and overall knowledge of COVID-19. Conclusion: Our findings showed some form of preparedness towards COVID-19 among healthcare workers. However, many aspects, such as the availability of PPEs and their proper use and knowledge, need improvement. Thus, training and an adequate supply of equipment are required to better respond to upcoming COVID-19 waves and future outbreaks. Doi: 10.28991/SciMedJ-2021-03-SI-5 Full Text: PDF

Summary. The first known case of infection from the novel coronavirus was recorded almost one year ago, in China’s Hubei province. The city of Wuhan was infamous the world over as the original virus epicenter, seeing more than half of China’s reported cases and deaths. The outbreak of COVID-19 virus, as sickened more than 14.7 million people. At least 610.200 people have died. The aim of the study – to analyze and systematize the literature data about the influence of chronic diseases on the manifestation of COVID-19 infection. Materials and Methods. The study uses publications of the world scientific literature on COVID-19 infection, in particular the causes and mechanisms of its development, treatment, complications and its consequences as well as the influence of different chronic disorders on the course of COVID-19. Results. A sample of patients hospitalized with COVID-19 across 14 states of the USA in March was analyzed by The Centers for Disease Control and Prevention. It was found that many (89 %) had underlying health problem and 94 % of patients were at the age 65 and older. The case fatality rate for those under age 60 was 1.4 percent. For those over age 60, the fatality rate jumps to 4.5 percent. The older the population, the higher the fatality rate. For those 80 and over, Covid-19 appears to have a 13.4 percent fatality rate. Moreover, it was recognized, that older adults don't present in a typical way of the course of different disorders, and we're seeing that with Covid-19 as well. Conclusions. Chronic diseases and conditions are on the rise worldwide. COVID-19 became the most challenging pandemic influencing all countries worldwide. Chronic diseases are suggested to be one of the main causes of different life-threatening complications of COVID-19 infection and one of the main factors of poor prognosis for the patients.
