Background: Troponin-I is conventionally correlated with myocardial injury, but its relevance in assessing the severity of coronavirus disease 2019 (COVID-19) and its implications for patient management remains an area of ongoing investigation. This study was designed to assess the correlation between troponin-I levels and the disease severity among patients with COVID-19. Materials and Methods: This retrospective study was conducted at a tertiary care center in India between April 2020 and November 2021. The patients with reverse transcription-polymerase chain reaction who tested positive for COVID-19 infection, and who underwent troponin-I examination at presentation were included in the study. A comparison of baseline clinical characteristics among patients who survived and who did not survive post-COVID-19 was done, and risk factors associated with mortality among hospitalized patients were analyzed. Results: A total of 1673 patients were enrolled in this study. Of these, 1431 patients survived, and 242 patients did not survive post-COVID-19. The mean age of the patients with troponin-I levels ≤0.06 ng/ml was 49.66 ± 17.88 years and that of patients with troponin-I levels >0.06 ng/ml was 60.13 ± 20.04 years. The nonsurvival rate was high in patients aged >50 years compared to the patients aged ≤50 years (81.4% vs. 18.6%; P < 0.001). The mortality rate was high in patients with troponin-I levels >0.06 ng/ml compared to the patients with troponin-I levels ≤0.06 ng/ml (51.7% vs. 48.3%; P < 0.001). Breathlessness (odds ratio [OR]: 26.901; P < 0.001), cut-off troponin-I levels (OR: 8.246; P < 0.001), and other comorbidities (OR: 8.246; P < 0.001) were independently correlated with mortality among hospitalized patients with COVID-19. Conclusion: This study demonstrated that elevated troponin-I level at presentation was associated with disease severity and increased mortality in patients with COVID-19.

Inadequate bioavailability is the main impediment to the therapeutic effects of oral Cur. This study aimed to develop an optimal curcumin transferosome-loaded thermosensitive in situ gel to improve its delivery to the lungs.Methods: Transferosomes were developed by using 33 screening layouts. The phospholipid concentration as well as the concentration and type of surfactant were considered independent variables. The entrapment efficiency (EE%), size, surface charge, and polydispersity index (PDI) were regarded as dependent factors. A cold technique was employed to develop thermosensitive in-situ gels. Optimized transferosomes were loaded onto the selected gels. The produced gel was assessed based on shape attributes, ex vivo permeability enhancement, and the safety of the nasal mucosa. The in vitro cytotoxicity, antiviral cytopathic effect, and plaque assay (CV/CPE/Plaque activity), and in vivo performance were evaluated after intranasal administration in experimental rabbits.Results: The optimized preparation displayed a particle size of 664.3 ± 69.3 nm, EE% of 82.8 ± 0.02%, ZP of − 11.23 ± 2.5 mV, and PDI of 0.6 ± 0.03. The in vitro curcumin release from the optimized transferosomal gel was markedly improved compared with that of the free drug-loaded gel. An ex vivo permeation study revealed a significant improvement (2.58-fold) in drug permeability across nasal tissues of sheep. Histopathological screening confirmed the safety of these preparations. This formulation showed high antiviral activity against SARS-CoV-2 at reduced concentrations. High relative bioavailability (226.45%) was attained after the formula intranasally administered to rabbits compared to the free drug in-situ gel. The curcumin transferosome gel displayed a relatively high lung accumulation after intranasal administration.Conclusion: This study provides a promising formulation for the antiviral treatment of COVID-19 patients, which can be evaluated further in preclinical and clinical studies.Graphical Abstract: Keywords: transferosomes, curcumin, in situ gels, coronavirus 2, SARS-CoV-2, intranasal delivery

BackgroundThe association of antihypertensive drugs with the risk and severity of COVID-19 remains unknown.Methods and resultsWe systematically searched PubMed, MEDLINE, The Cochrane Library, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, and medRxiv for publications before July 13, 2020. Cohort studies and case-control studies that contain information on the association of antihypertensive agents including angiotensin-converting enzyme inhibitors (ACEIs), angiotensin II receptor blockers (ARBs), calcium-channel blockers (CCBs), β-blockers, and diuretics with the risk and severity of COVID-19 were selected. The random or fixed-effects models were used to pool the odds ratio (OR) with 95% confidence interval (CI) for the outcomes. The literature search yielded 53 studies that satisfied our inclusion criteria, which comprised 39 cohort studies and 14 case-control studies. These studies included a total of 2,100,587 participants. We observed no association between prior usage of antihypertensive medications including ACEIs/ARBs, CCBs, β-blockers, or diuretics and the risk and severity of COVID-19. Additionally, when only hypertensive patients were included, the severity and mortality were lower with prior usage of ACEIs/ARBs (overall OR of 0.81, 95% CI 0.66-0.99, p < 0.05 and overall OR of 0.77, 95% CI 0.66-0.91, p < 0.01).ConclusionsTaken together, usage of antihypertensive drugs is not associated with the risk and severity of COVID-19. Based on the current available literature, it is not recommended to abstain from the usage of these drugs in COVID-19 patients.RegistrationThe meta-analysis was registered on OSF (https://osf.io/ynd5g).

Coronavirus disease is an infectious disease caused by severe acute respiratory syndrome-coronavirus 2 virus. It predominantly affects respiratory system causing fever, cough, and breathlessness. But it can also affect central nervous system and peripheral nervous system. It is important that physicians keep a high index of suspicion for patients with neurologic symptoms following a recent or during COVID-19 infection. The low rate of initial diagnosis is alarming, as few of the percentage of patients with Guillain-Barre syndrome will develop respiratory muscle weakness requiring invasive ventilation. The ability to recognize the disease process could lead to life saving management. Furthermore, the initiation of therapy such as plasma exchange or intravenous immunoglobulin leads to an accelerated recovery time.

Multisystem inflammatory syndrome in children (MIS-C) is a serious health condition that imposes a long-term follow-up. The purpose of our pilot study is to evaluate the usefulness of the cardiopulmonary stress test (CPET) in the follow-up after MIS-C. All patients admitted for MIS-C in our hospital in the 12 months preceding the date of observation were considered for inclusion in the study. Pre-existing cardio-respiratory diseases and/or the lack of collaboration were the exclusion criteria. At enrolment, each subject passed a cardiological examination, rest ECG, echocardiogram, 24 h Holter-ECG, blood tests, and a CPET complete of spirometry. A total of 20 patients met the inclusion criteria (11.76 ± 3.29 years, 13 male). In contrast to the normality of all second-level investigations, CPET showed lower-than-expected peakVO2 and peak-oxygen-pulse values (50% of cases) and higher-than-expected VE/VCO2-slope values (95% of cases). A statistically significant inverse correlation was observed between P-reactive-protein values at admission and peakVO2/kg values (p = 0.034), uric acid values at admission, and peakVO2 (p = 0.011) or peak-oxygen-pulse expressed as a percentage of predicted (p = 0.021), NT-proBNP values at admission and peakVO2 expressed as a percentage of predicted (p = 0.046). After MIS-C (4–12 months) relevant anomalies can be observed at CPET, which can be a valuable tool in the follow-up after this condition. [ABSTRACT FROM AUTHOR]

The effect of the COVID-19 related stressors on the mental health of both infected patients and the general public has been well established. However, knowledge is limited on how psychosocial support buffers the association. This study aimed to examine this buffering role in the context of China. We utilized cross-sectional data collected online in mid-March 2020, involving 585 respondents. Mental health status was determined through depression symptoms and loneliness. COVID-19 related stressors include three aspects: perceived severity, perceived threat to life and health, and perceived risk of COVID-19 infection. Psychosocial support included family and social supports. Analyses include ordinary linear regression. The finding showed that psychosocial support buffered the negative effect of loneliness in the context of perceived severity of COVID-19, but appeared to intensify the negative effect of depression symptoms in the context of perceived threat to life and health. However, there was no significant buffering effect on depression or loneliness in the context of the perceived risk of infection. The buffering effect of psychosocial support on COVID-19 related stressors is of mixed patterns. This study contributes to the emerging body of literature trying to understand how the COVID-19 impacts the mental health of individuals. [ABSTRACT FROM AUTHOR]

Objective: Dynamic changes in the number of eosinophils are observed during the diagnosis and follow-up in coronavirus disease-2019 (COVID-19). Our aim was to show the role of the absolute eosinophil count in the diagnosis of COVID-19 and the relationship with disease severity and prognosis. Methods: In this study, 191 patients (130 inpatients, 61 outpatients) diagnosed with COVID-19 pneumonia with the polymerase chain reaction test and lung computed tomography; and 22 patients with positive influenza test were included as the control group. All demographic, biochemical data, clinical and radiological characteristics were recorded. Results: The mean eosinophils on first day of the inpatient COVID-19 group were found to be statistically lower than the influenza group and the ambulatory groups (p=0.001, p=0.0001). Conclusion: A low eosinophil count in complete blood count, can aid in the early diagnosis of infection. Persistent eosinopenia progresses with disease severity and may help determine the prognosis of the disease. [ABSTRACT FROM AUTHOR]

Abstract Objectives: reviewing the available literature on COVID-19 infection and the maternal and perinatal outcomes. Methods: this is a narrative review of the literature carried out from March to September 2020, usingthe MESH: coronavirus, Covid 19, SARS-CoV-2, pregnancy, gravidity, pregnancy complications and pregnancy complications infectius. All study designs, reviews, recommendations and technical notes were included, without distinction of language and that would bring the approach of the new coronavirus in the gestational and perinatal scenario. Results: the COVID-19 pandemic has had devastating effects, affecting millions of people and claiming almost a million lives worldwide. Initially, pregnant women were not seen as a risk group for the disease, however as the proportion of women affected during the pregnancy-puerperal cycle increased, several studies were published showing an increased risk of complications. Brazilian studies have also warned of a high number of maternal deaths, associated with the presence of comorbidities but, above all, with the social determinants of the disease and serious failures in care. Conclusion: the need for new studies with an adequate research design was observed, as many studies are only letters or small series of cases, in addition expert recommendations, without the necessary scientific rigor.

The coronavirus disease 2019 (COVID-19) epidemic, which is caused by novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has continued to spread around the world since December 2019. Healthcare workers and other medical first responders in particular need personal protective equipment to protect their respiratory system from airborne particulates, in addition to liquid splashes to the face. N95 respirator have become a critical component for reducing SARS-CoV-2 transmission and controlling the scale of the COVID-19 pandemic. However, a major dispute concerning the protective performance of N95 respirators has erupted, with a myriad of healthcare workers affected despite wearing N95 masks. This article reviews the most recent updates about the performance of N95 respirators in protecting against the SARS-CoV-2 virus in the present pandemic situation. A brief overview of the manufacturing methods, air filtration mechanisms, stability, and reusability of the mask is provided. A detailed performance evaluation of the mask is studied from an engineering point of view. This Review also reports on a comparative study about the protective performance of all commercially available surgical and respiratory masks used to combat the spread of COVID-19. With the aim of protecting healthcare providers more efficiently, we suggest some potential directions for the development of this respiratory mask that improve the performance efficiency of the mask.

Abstract Objectives: to review the available literature on the general aspects of SARS-CoV-2 infec-tion. Methods: this is a narrative literature review carried out from March to September 2020. Results: COVID-19 caused by the new coronavirus or SARS-CoV-2, grows with devas-tating effects worldwide. The literature describes epidemiological data and mortality risk groups of the disease, which presents a high rate of transmission. Prevention is the most effective way to fight the disease, persisting the absence of strong evidence on the treatment. Vaccines are not yet available. Dexamethasone is effective in reducing mortality in severe forms. Conclusions: despite great efforts, as the number of confirmed cases increases, evidence on transmission, incidence, disease progression, lethality, effects and outcomes remain limited and without any high levels of evidence. Studies are still necessary for all aspects of the disease.

Background and Aims: Most data on electrocardiographic (ECG) changes in patients with coronavirus disease-19 (COVID-19) have been presented without comparison to patients with other acute respiratory illnesses. The correlation of ECG changes with disease severity has also not been studied. Subjects and Methods: We compared forty COVID-19-positive and forty COVID-19-negative patients in terms of clinical presentation, ECG at admission, and cardiac biomarkers. Statistical analysis was presented as frequency (percentage) and continuous as mean ± standard deviation. Chi-square test/Fischer's exact test was used. Results: Mean age overall in the study was 52.4 ± 16 years, 67.5% data were males. About 87.5% of the COVID-positive patients and 70% of the COVID-negative patients had ECG changes at baseline. Sinus tachycardia was seen in 45% (18/40) of COVID-positive patients. About 95% (38/40) of COVID-19 positive patients had normal axis, 5% (2/40) had supraventricular tachycardia, 2.5% (1/40) had premature atrial contractions (PACs), and 7.5% (3/40) had premature ventricular contractions. One patient had ventricular bigeminy. About 7.5% (3/40) of COVID-positive cases had complete right bundle branch block (RBBB), one had complete left bundle branch block (LBBB), whereas one had incomplete LBBB. About 7.5% (3/40) of COVID-positive cases had ST-segment elevation, one of whom also developed postmyocardial infarction left ventricular thrombus. About 15% (6/40) had nonST-segment elevation acute coronary syndrome. Conclusions: COVID-19 patients have ECG changes of left-sided heart disease (PACs and LBBB) and right-sided disease (RBBB, right axis deviation, and right ventricular strain pattern) at presentation, however, right heart changes predominate. COVID-19 patients had a higher occurrence and a wider variety of ECG changes at presentation than other acute respiratory illnesses and these changes correlate well with clinical disease severity as does troponin I level.

Background The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic poses an urgent need for the development of effective therapies for coronavirus disease 2019 (COVID-19). Methods We first tested SARS-CoV-2–specific T-cell (CοV-2-ST) immunity and expansion in unexposed donors, COVID-19–infected individuals (convalescent), asymptomatic polymerase chain reaction (PCR)–positive subjects, vaccinated individuals, non–intensive care unit (ICU) hospitalized patients, and ICU patients who either recovered and were discharged (ICU recovered) or had a prolonged stay and/or died (ICU critical). CoV-2-STs were generated from all types of donors and underwent phenotypic and functional assessment. Results We demonstrate causal relationship between the expansion of endogenous CoV-2-STs and the disease outcome; insufficient expansion of circulating CoV-2-STs identified hospitalized patients at high risk for an adverse outcome. CoV-2-STs with a similarly functional and non-alloreactive, albeit highly cytotoxic, profile against SARS-CoV-2 could be expanded from both convalescent and vaccinated donors generating clinical-scale, SARS-CoV-2–specific T-cell products with functional activity against both the unmutated virus and its B.1.1.7 and B.1.351 variants. In contrast, critical COVID-19 patient-originating CoV-2-STs failed to expand, recapitulating the in vivo failure of CoV-2–specific T-cell immunity to control the infection. CoV-2-STs generated from asymptomatic PCR-positive individuals presented only weak responses, whereas their counterparts originating from exposed to other seasonal coronaviruses subjects failed to kill the virus, thus disempowering the hypothesis of protective cross-immunity. Conclusions Overall, we provide evidence on risk stratification of hospitalized COVID-19 patients and the feasibility of generating powerful CoV-2-ST products from both convalescent and vaccinated donors as an "off-the shelf" T-cell immunotherapy for high-risk patients.

Introduction and Objectives: As of January 2021, over 88 million people have been infected with COVID-19. Almost two million people have died of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A high SOFA score and a D-Dimer >1 μg/mL identifies patients with high risk of mortality. High lactate dehydrogenase (LDH) levels on admission are associated with severity and mortality. Different degrees of alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) abnormalities have been reported in these patients, its association with a mortality risk remains controversial. The aim of this study was to explore the correlation between LDH and in-hospital mortality in Mexican patients admitted with COVID-19. Materials & Methods: We performed a retrospective multi-centre cohort study with 377 hospitalized patients with confirmed SARS-CoV-2 in three centres in Mexico City, Mexico, who were =18 years old and died or were discharged between April 1 and May 31, 2020. Results: A total of 377 patients were evaluated, 298 (79.1%) patients were discharged, and 79 (20.9%) patients died during hospitalization. Non-survivors were older, with a median age of 46.7 ± 25.7 years old, most patients were male. An ALT > 61 U/l (OR 3.45, 95% CI 1.27-9.37; p = 0.015), C-reactive protein (CRP) > 231 mg/l (OR 4.71, 95% CI 2.35-9.46; p = 0.000), LDH > 561 U/l (OR 3.03, 95% CI 1.40-6.55; p = 0.005) were associated with higher odds for in-hospital death. Conclusions: Our results indicate that higher levels of LDH, CRP, and ALT are associated with higher in-hospital mortality risk in Mexican patients admitted with COVID-19. [ABSTRACT FROM AUTHOR]

Coronavirus disease 2019 (COVID-19), an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is responsible for the most threatening pandemic in modern history. The aim of this systematic review and meta-analysis was to investigate the associations between serum albumin concentrations and COVID-19 disease severity and adverse outcomes. A systematic literature search was conducted in PubMed, from inception to October 30, 2020. Sixty-seven studies in 19,760 COVID-19 patients (6141 with severe disease or poor outcome) were selected for analysis. Pooled results showed that serum albumin concentrations were significantly lower in patients with severe disease or poor outcome (standard mean difference, SMD: − 0.99 g/L; 95% CI, − 1.11 to − 0.88, p < 0.001). In multivariate meta-regression analysis, age (t = − 2.13, p = 0.043), publication geographic area (t = 2.16, p = 0.040), white blood cell count (t = − 2.77, p = 0.008) and C-reactive protein (t = − 2.43, p = 0.019) were significant contributors of between-study variance. Therefore, lower serum albumin concentrations are significantly associated with disease severity and adverse outcomes in COVID-19 patients. The assessment of serum albumin concentrations might assist with early risk stratification and selection of appropriate care pathways in this group. [ABSTRACT FROM AUTHOR]

COVID-19 is currently a major cause of morbidity and mortality in adults throughout the world. Given the high infection rate, it is increasingly likely that histopathologists will encounter this disease during their practice. Although COVID-19 is increasingly recognized as a multi-system disease, the lungs and, to a lesser degree, the heart remain the major sites of pathology. This article aims to acquaint the general histopathologist with the main pathological findings in the lungs and heart of adults with COVID-19. It highlights the need for clinicopathological correlation with a discussion of the cardiopulmonary clinical features in COVID-19 and relates those to the pathological findings. In the lungs, diffuse alveolar damage is emphasized with its variety of morphological appearances over time. It concludes with a discussion of the main techniques available to identify the virus in fixed tissues and their potential limitations related specifically to the heart and lungs.

BACKGROUND: With the spread of COVID-19 and the worsening global prevention and control situation, the risk of infection faced by health workers has been unprecedented. It is necessary to fully understand the occupational risks of health workers to protect them and reduce their risk of infection. OBJECTIVE: This study aimed to obtain comprehensive and detailed information on occupational risk factors of infectious diseases for HWs in different dimensions and to propose control strategies for three risk dimensions to protect HWs who are at high risk of infection during the pandemic. METHODS: A total number of 619 articles published from 2010 to 2021 were searched to conduct bibliometric analysis, which were retrieved in the Web of Science database with defined search terms. There were 26 articles met the criteria, and they were screened to identify occupational risk factors. RESULTS: We conducted an analysis of cited institutions, co-citation network analysis of journals, and references from bibliometric analysis. Nine risk factors were extracted, and they were classified and sorted into three dimensions. Infection control strategies for each dimension were proposed. CONCLUSIONS: The risk of infection faced by HWs is unprecedented. Medical institutions should pay more attention to the nine risk factors that we identified and use the three risk dimensions to carry out risk identification and infection control to reduce the infection risk of HWs and protect them better.

The corona virus disease 2019 (COVID-19) pandemic sweeping across the world has severely strained health care resources (equipment and personnel) forcing us to rethink strategies to provide obstetric care while judiciously using resources. We describe the anaesthetic management of a mildly symptomatic, COVID-19 positive, 28-year-old second gravida with term pregnancy who was taken up for an elective caesarean section under subarachnoid block in a standalone maternity facility. Challenges encountered and modifications of standard procedures so as to optimize patient care and minimize exposure of health care professionals are also discussed.

The aim of this quality improvement project was to survey commonalities among healthcare personnel (HCP) who tested positive for COVID-19 and to evaluate the effectiveness the organizational intervention to require HCP wear masks throughout their shift. Information regarding the 40 HCP who tested positive for COVID-19 between the dates of March 18, 2020 and May 13, 2020 were included in the analysis. Nurses (n = 9) made up the majority of HCP positive for COVID-19. The most common types of symptoms reported were cough (n = 26), headache (n = 20), and fever (n = 13). Fourteen days after the requirement for HCP across the organization to wear masks throughout their shift was implemented, a 67% reduction in positive tests among HCP involved in a workplace exposure was observed.

The outbreak of existing public health distress is threatening the entire world with emergence and rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel coronavirus disease 2019 (COVID-19) is mild in most people. However, in some elderly people with co-morbid conditions, it may progress to pneumonia, acute respiratory distress syndrome (ARDS) and multi organ dysfunction leading to death. COVID-19 has caused global panic in the healthcare sector and has become one of the biggest threats to the global economy. Drug discovery researchers are expected to contribute rapidly than ever before. The complete genome sequence of coronavirus had been reported barely a month after the identification of first patient. Potential drug targets to combat and treat the coronavirus infection have also been explored. The iterative structure-based drug design (SBDD) approach could significantly contribute towards the discovery of new drug like molecules for the treatment of COVID-19. The existing antivirals and experiences gained from SARS and MERS outbreaks may pave way for identification of potential drug molecules using the approach. SBDD has gained momentum as the essential tool for faster and costeffective lead discovery of antivirals in the past. The discovery of FDA approved human immunodeficiency virus type 1 (HIV-1) inhibitors represent the foremost success of SBDD. This systematic review provides an overview of the novel coronavirus, its pathology of replication, role of structure based drug design, available drug targets and recent advances in in-silico drug discovery for the prevention of COVID-19. SARSCoV- 2 main protease, RNA dependent RNA polymerase (RdRp) and spike (S) protein are the potential targets, which are currently explored for the drug development.

Background: COVID-19 has affected the educational system, particularly students of higher educational institutions. Accurate knowledge about the disease, its transmission, and preventive measures are critical for containing an outbreak. University students, the next generation of professionals, may play an imperative role in propagating key health information to society. Objectives: The study aims to assess the level of knowledge, the attitude of concern, and prevention practices among university students towards COVID-19 prevention. Methods: This descriptive study was conducted at a private higher educational institution in Central Luzon, Holy Angel University. 357 university students were recruited as study participants from the university's different departments using the purposive sampling method, and data were collected using an online self-administered questionnaire. Results: Among the 357 university students who completed the questionnaires, most were females (58.5%). The results show a good level of attitude of concern and good knowledge of clinical manifestations of COVID-19. The students' most frequently stated source of transmission is exposure to coughing and sneezing via droplets. Additionally, wearing face masks was the most reported method of protection against the infection. Conclusion: The study revealed that university students have adequate knowledge, practices, and attitude of concern towards COVID-19. To bridge the gap between current and required knowledge, it is essential to establish further professional educational campaigns to increase university students' awareness of the pandemic.

Vitamin D deficiency seems to be associated with severe outcome in the patients with COVID -19. Since the beginning of the pandemic till date this has sparked various discussions, researches and randomised control trails, with many more underway. It seems that vitamin D can be a promising factor in the fight against this pandemic. It enhances our innate and adaptive immunity and ultimately kills the virus. It has also been seen as a potential agent to damper the cytokine storm which causes severe outcome in these infected patients. Supplementation of Vitamin D is being considered by many governments across the globe in view of these associations and benefits. [ABSTRACT FROM AUTHOR]

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was first identified in December 2019 in Wuhan, China. Since then, the virus has been rapidly spreading across countries, resulting in the present Corona Virus Disease (COVID-2019) pandemic. Thousands of genomes of different strains of the virus have been sequenced and made available in the public domain which has helped to detect viral mutations and track movement of the virus across the globe. The whole genome sequence of SARS-CoV-2 isolated from a human strain has 96.2% similarity to a bat coronavirus. The strains of SARS-CoV-2 found in different countries are genetically diverse and infections have been shown to be caused by multiple introductions in the same country. Though there are several theories regarding the origin of this virus, genetic studies indicate that it may have appeared by natural selection in humans following zoonotic transfer. This review highlights the recent knowledge of the origin of the coronavirus, its diversity in different geographical regions and mutations, which have aided it to infect the human host.

Introduction: The low frequency of cases and deaths from the SARS-CoV-2 COVID-19 virus in some countries of Africa has called our attention about the unusual behavior of this disease. The ivermectin is considered a drug of choice for various parasitic and viral diseases and shown to have in vitro effects against SARS-CoV-2. Aims: Our study aimed to describe SARS-CoV2 infection and death rates in African countries that participated in an intensive Ivermectin mass campaign carried out to control onchocerciasis and compare them with those of countries that did not participate. Methods: Data from 19 countries that participated in the World Health Organization (WHO) sponsored African Programme for Onchocerciasis Control (APOC), from 1995 until 2015, were compared with thirty-five (Non-APOC), countries that were not included. Information was obtained from https://www.worldometers.info/coronavirus/database. Generalized Poisson regression models were used to obtain estimates of the effect of APOC status on cumulative SARS-CoV-2 infection and mortality rates. Results: After controlling for different factors, including the Human Development Index (HDI), APOC countries (vs. non-APOC), show 28% lower mortality (0.72; 95% CI: 0.67-0.78) and 8% lower rate of infection (0.92; 95% CI: 0.91-0.93) due to COVID-19. Conclusion: The incidence in mortality rates and number of cases is significantly lower among the APOC countries compared to non-APOC countries. That a mass public health preventive campaign against COVID-19 may have taken place, inadvertently, in some African countries with massive community ivermectin use is an attractive hypothesis. Additional studies are needed to confirm it. [ABSTRACT FROM AUTHOR]

Background: We need high-quality data to assess the determinants for COVID-19 severity in people with MS (PwMS). Several studies have recently emerged but there is great benefit in aligning data collection efforts at a global scale. Objectives: Our mission is to scale-up COVID-19 data collection efforts and provide the MS community with data-driven insights as soon as possible. Methods: Numerous stakeholders were brought together. Small dedicated interdisciplinary task forces were created to speed-up the formulation of the study design and work plan. First step was to agree upon a COVID-19 MS core data set. Second, we worked on providing a user-friendly and rapid pipeline to share COVID-19 data at a global scale. Results: The COVID-19 MS core data set was agreed within 48 hours. To date, 23 data collection partners are involved and the first data imports have been performed successfully. Data processing and analysis is an on-going process. Conclusions: We reached a consensus on a core data set and established data sharing processes with multiple partners to address an urgent need for information to guide clinical practice. First results show that partners are motivated to share data to attain the ultimate joint goal: better understand the effect of COVID-19 in PwMS. [ABSTRACT FROM AUTHOR]

Reinstating elective hip and knee arthroplasty services presents significant challenges. We need to be honest about the scale of the obstacles ahead and realise that the health challenges and economic consequences of the COVID-19 pandemic are potentially devastating. We must also prepare to make difficult ethical decisions about restarting elective hip and knee arthroplasty. These decisions should be based on the existing evidence-base, reliable data, the recommendations of experts, and regional circumstances. [ABSTRACT FROM AUTHOR]

The article informs that international perspectives concerning donor milk banking during the SARSCoV- 2 (COVID-19) Pandemic. Topics include neonatal throat swabs, and milk samples from six of the mothers were tested for SARS-CoV-2, and all samples tested negative for the virus; and the concerns for the general public, there are heightened concerns for the more at risk populations with comorbidities.

Background: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), first identified in Wuhan, China, has resulted within the coronavirus disease 19 (COVID-19) pandemic that has spread to 210 countries worldwide. At the time of scripting this review, 76,726 people had been infected with and 411 died from SARS-CoV-2 in Kingdom of Saudi Arabia. COVID-19 has deeply impacted the lives of millions globally, either directly or as a results of the preventive measures instituted to regulate the spread of the disease. Research groups worldwide are working hard to develop sensitive and specific diagnostic tools and effective vaccines. This review aimed to supply relevant COVID- 19 research data obtained from a literature review. Conclusion: We believe that our study makes significant contributions to the literature because it provides a condensed, authoritative presentation of the numerous clinical presentations, diagnoses, treatments, and patient management strategies for COVID-19. It also as reports on this COVID-19 situation in Kingdom of Saudi Arabia. [ABSTRACT FROM AUTHOR]

Introduction: The aim of this study is to report our clinical experience in the management of pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the first 30 days of the coronavirus disease (COVID-19) pandemic.Material and Methods: We reviewed clinical data from the first 60 pregnant women with COVID-19 whose care was managed at Puerta de Hierro University Hospital, Madrid, Spain from 14 March to 14 April 2020. Demographic data, clinical findings, laboratory test results, imaging findings, treatment received, and outcomes were collected. An analysis of variance (Kruskal-Wallis test) was performed to compare the medians of laboratory parameters. Fisher's exact test was used to evaluate categorical variables. A correspondence analysis was used to explore associations between variables.Results: A total of 60 pregnant women were diagnosed with COVID-19. The most common symptoms were fever and cough (75.5% each) followed by dyspnea (37.8%). Forty-one women (68.6%) required hospital admission (18 because of disease worsening and 23 for delivery) of whom 21 women (35%) underwent pharmacological treatment, including hydroxychloroquine, antivirals, antibiotics, and tocilizumab. No renal or cardiac failures or maternal deaths were reported. Lymphopenia (50%), thrombocytopenia (25%), and elevated C-reactive protein (CRP) (59%) were observed in the early stages of the disease. Median CRP, D-dimer, and the neutrophil/lymphocyte ratio were elevated. High CRP and D-dimer levels were the parameters most frequently associated with severe pneumonia. The neutrophil/lymphocyte ratio was found to be the most sensitive marker for disease improvement (relative risk 6.65; 95% CI 4.1-5.9). During the study period, 18 of the women (78%) delivered vaginally. All newborns tested negative for SARS-CoV-2 and none of them were infected during breastfeeding. No SARS-CoV-2 was detected in placental tissue.Conclusions: Most of the pregnant women with COVID-19 had a favorable clinical course. However, one-third of them developed pneumonia, of whom 5% presented a critical clinical status. CRP and D-dimer levels positively correlated with severe pneumonia and the neutrophil/lymphocyte ratio decreased as the patients improved clinically. Seventy-eight percent of the women had a vaginal delivery. No vertical or horizontal transmissions were diagnosed in the neonates during labor or breastfeeding. [ABSTRACT FROM AUTHOR]

Background: COVID-19 has affected the educational system, particularly students of higher educational institutions. Accurate knowledge about the disease, its transmission, and preventive measures are critical for containing an outbreak. University students, the next generation of professionals, may play an imperative role in propagating key health information to society. Objectives: The study aims to assess the level of knowledge, the attitude of concern, and prevention practices among university students towards COVID-19 prevention. Methods: This descriptive study was conducted at a private higher educational institution in Central Luzon, Holy Angel University. 357 university students were recruited as study participants from the university's different departments using the purposive sampling method, and data were collected using an online self-administered questionnaire. Results: Among the 357 university students who completed the questionnaires, most were females (58.5%). The results show a good level of attitude of concern and good knowledge of clinical manifestations of COVID-19. The students' most frequently stated source of transmission is exposure to coughing and sneezing via droplets. Additionally, wearing face masks was the most reported method of protection against the infection. Conclusion: The study revealed that university students have adequate knowledge, practices, and attitude of concern towards COVID-19. To bridge the gap between current and required knowledge, it is essential to establish further professional educational campaigns to increase university students' awareness of the pandemic.
