Effect of Rosuvastatin in the Protection against Azithromycin Induced Cardiotoxicity in Covid-19 Patients: A One-Year Prospective Study

Background Azithromycin is a widely used broad-spectrum antibiotic that was recently used in the treatment protocol of COVID-19 but its cardiac side effects became a more prominent concern. Rosuvastatin is a synthetic statin that showed anti-inflammatory, antioxidant and autonomic nervous system regulatory effects in addition, there is increasing evidence supporting that it could play a beneficial role in patients with COVID-19. Objective To evaluate the protective effect of Rousvastatin against Azithromycin-induced cardiotoxicity in Covid-19 patients. Patients and Methods This is a prospective study that was conducted on adult patients diagnosed with COVID-19 who were admitted to isolation centres in Minia Governorate, Egypt for the period of one year (June 2021 to May 2022). The study included a total of 80 COVID-19 patients who were divided into 2 groups (n=40 each), group (I) "Azithromycin group" that included patients received Azithromycin (500 mg/day for 5 days) orally and group (II) "Azithromycin + Rosuvastatin group" that included patients received Azithromycin by oral route as group (I) plus Rosuvastatin 20 mg/day orally. All included cases were subjected to full history taking, clinical examination and laboratory investigations and after treatment, the outcome measures were reported and compared. Results No significant differences were observed between groups regarding demographic and baseline characteristics. Also, the two groups were comparable with no significant differences in pulse rate, blood sugar, CBC, electrolyte elements, liver enzymes, and kidney function (a slight reduction was noticed in group II). While, Ferritin level was significantly lower in group (II) compared to group (I), (830 +/- 72.5 vs. 865 +/- 69.5, p=0.03). No significant differences were observed among groups as regards Troponin level (p=0.56) "Only one case was positive in group (I)". Both groups were almost comparable without significant differences in both stages of infection and mortality (p=0.38 and 1.0, respectively). Conclusion Rosuvastatin did not have a significant role in the protection of Azithromycin-induced cardiotoxicity, it slightly ameliorates the biochemical and stress markers alterations of Azithromycin. Further larger studies are warranted for investigating this issue. Copyright © 2023 Wolters Kluwer Medknow Publications. All rights reserved.

Influence of COVID-19 on the sustainability of livestock performance and welfare on a global scale.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is currently spreading worldwide. The pandemic has already had significant adverse effects on human civilization, the environment, and the ecosystem at national and global levels. Moreover, the various sectors of the food production chain, particularly agriculture and livestock, have also been significantly affected in terms of production sustainability and economic losses. The global pandemic has already resulted in a sharp drop in meat, milk, and egg production. Restrictions of movement at national and international levels, implemented as a part of control strategies by public health sectors, have negatively impacted business related to the supply of raw materials for livestock farmers and farm outputs, veterinary services, farmworkers, and animal welfare. This review highlights the significant impacts of COVID-19 on the sustainability of livestock performance, welfare on a global scale, and strategies for mitigating these adverse effects.

Right Ventricular Diastolic Dysfunction in Young Adults after Mild COVID-19

Background: Myocardial injury is neither limited to the acute Coronavirus disease 2019 nor moderate-to-severe cases. Objectives: This study aimed to evaluate the relationship between right ventricular diastolic dysfunction and post-Coronavirus disease 2019 cardiovascular sequelae in young adults with mild disease. Patients and Methods: This study recruited 150 young adults (between 18 and 30 years) who were classified into three equal groups: Group A included 50 patients who sustained cardiac symptoms 12 to 14 weeks following mild Coronavirus disease 2019. Group B included 50 patients who did not show cardiac symptoms 12 to 14 weeks following mild Coronavirus disease 2019. Group C included 50 gender-matched healthy subjects of similar ages without previous Coronavirus disease 2019. Each subject underwent a detailed transthoracic echocardiographic study to detect right ventricular diastolic dysfunction by measuring the tricuspid valve E/A ratio, tricuspid deceleration time, tricuspid E/e' ratio and tricuspid e'/a' ratio. Results: Right ventricular diastolic dysfunction was higher in group A (80% versus 30% versus 0%, p < 0.001). Tricuspid valve e’/a’ was lower in group A (0.86 ± 0.2 versus 1.08 ± 0.2 versus 1.44 ± 0.28, p < 0.001) while tricuspid valve E/ e’ was higher (6.7 ± 1.1 versus 3.25 ± 3 versus 3.04 ± 0.36, p < 0.001). Post-Coronavirus disease 2019 patients with right ventricular diastolic dysfunction had a higher right ventricular basal diameter, higher right ventricular systolic pressure, lower right ventricular tricuspid annular plane systolic excursion, and lower fractional area change. Conclusions: After recovery from mild Coronavirus disease 2019, some of young adults had right ventricular diastolic dysfunction, which was more prevalent in those with post-Coronavirus disease 2019 cardiac symptoms. © 2022, Ain Shams University Faculty of Medicine.

SARS-CoV-2 Reverse Transcription-Polymerase Chain Reaction Positivity and Seroprevalence among Health Care Workers in a Referral Cancer Institute: A Cross-sectional Study

BACKGROUND: During the ongoing coronavirus disease 2019 pandemic, healthcare workers (HCWs) are presumed to be at increased risk of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), transmitting the infection to vulnerable patients if they are not timeously isolated. AIM: This study aimed to determine the point prevalence of SARS-CoV-2 infection in a cohort of HCWs providing oncology services. METHODS AND RESULTS: HCWs in a large referral cancer hospital in Egypt were tested using real-time reverse transcription-polymerase chain reaction (RT-PCR) on nasopharyngeal swabs, and immunochromatography-based rapid serological test (RST). Clinical and epidemiological data were collected. In 2020, 999 HCWs were screened, of whom 86 tested positive for SARS-CoV-2 by RT-PCR (8.6%) and 127 subjects were seropositive for antibodies against SARS-CoV-2 by RST (12.8%). Immunoglobulin M seroprevalence demonstrated considerable concordance with RT-PCR positivity (sensitivity 82.14% and specificity 96.71%). Most HCWs (>95%) reported adherence to personal protective equipment. Patient transporters/cleaner were the group with the highest frequency of positive RT-PCR (19%) whereas laboratory and radiology technicians displayed the lowest frequency. Fever, dry cough, rhinorrhea, shortness of breath, fatigue and diarrhea were significantly associated with RT-PCR positivity, with increased likelihood of being positive with the presence of five or six simultaneous symptoms. CONCLUSIONS: The point prevalence of SARS-CoV-2 infection in screened HCWs is 8.6% by RT-PCR and seroprevalence is 12.8% by RST. Strict measures should be implemented to minimize transmission within healthcare settings and to the community. Our data support the importance of HCWs screening for SARS-CoV-2, taking in account the significant proportion of asymptomatic carriers. © 2022 Abdel-Rahman Zekri, Ola S.

Poultry Production and Sustainability in Developing Countries under the COVID-19 Crisis: Lessons Learned.

Poultry farming is a significant source of revenue generation for small farmers in developing countries. It plays a vital role in fulfilling the daily protein requirements of humans through meat and eggs consumption. The recently emerged pandemic Coronavirus Disease-19 (COVID-19) impacts the poultry production sector. Although the whole world is affected, these impacts may be more severe in developing countries due to their dependency on exporting necessary supplies such as feed, vaccines, drugs, and utensils. In this review, we have discussed poultry production in developing countries under the COVID-19 crisis and measures to regain the loss in the poultry industries. Generally, due to the lockdown, trade limitations have negatively impacted poultry industries, which might exacerbate global poverty. Coordinated activities have to be taken at the private and government levels to arrange soft loans so that these farms can restore their production and marketing to normal levels. In addition, here, we have focused on the supply of farm input, feed, other raw materials, management system, improved breeding efficiency, veterinary services, and marketing of egg and meat, which have to be ensured to secure a sustainable poultry production chain.

Diversity of Coronaviruses with Particular Attention to the Interspecies Transmission of SARS-CoV-2.

In December 2019, the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was reported in China with serious impacts on global health and economy that is still ongoing. Although interspecies transmission of coronaviruses is common and well documented, each coronavirus has a narrowly restricted host range. Coronaviruses utilize different receptors to mediate membrane fusion and replication in the cell cytoplasm. The interplay between the receptor-binding domain (RBD) of coronaviruses and their coevolution are determinants for host susceptibility. The recently emerged SARS-CoV-2 caused the coronavirus disease 2019 (COVID-19) pandemic and has also been reported in domestic and wild animals, raising the question about the responsibility of animals in virus evolution. Additionally, the COVID-19 pandemic might also substantially have an impact on animal production for a long time. In the present review, we discussed the diversity of coronaviruses in animals and thus the diversity of their receptors. Moreover, the determinants of the susceptibility of SARS-CoV-2 in several animals, with special reference to the current evidence of SARS-CoV-2 in animals, were highlighted. Finally, we shed light on the urgent demand for the implementation of the One Health concept as a collaborative global approach to mitigate the threat for both humans and animals.

Evolutionary insights into the furin cleavage sites of SARS-CoV-2 variants from humans and animals.

The SARS-CoV-2 spike protein Q677P/H mutation and furin cleavage site (FCS) have been shown to affect cell tropism and virus transmissibility. Here, we analyzed the frequency of Q677P/H and FCS point mutations in 1,144,793 human and 1042 animal spike protein sequences and from those of the emergent variants B.1.1.7, B.1.351, P.1, B.1.429 + B.1.427, and B.1.525, which were deposited in the database of the GISAID Initiative. Different genetic polymorphisms, particularly P681H and A688V, were detected in the FCS, mainly in human isolates, and otherwise, only pangolin and bat sequences had these mutations. Multiple FCS amino acid deletions such as Δ680SPRRA684 and Δ685RSVA688 were only detected in eight and four human isolates, respectively. Surprisingly, deletion of the entire FCS motif as Δ680SPRRARSVA688 and Δ680SPRRARSVAS689 was detected only in three human isolates. On the other hand, analysis of FCS from emergent variants showed no deletions in the FCS except for spike P681del, which was detected in seven B.1.1.7 isolates from the USA. Spike Q677P was detected only once in variant, B.1.1.7, whereas Q677H was detected in all variants, i.e., B.1.1.7 (n = 1938), B.1.351 (n = 28), P.1 (n = 9), B.1.429 + B.1.427 (n = 132), and B.1.525 (n = 1584). Structural modeling predicted that mutations or deletions at or near the FCS significantly alter the cleavage loop structure and would presumably affect furin binding. Taken together, our results show that Q677H and FCS point mutations are prevalent and may have various biological effects on the circulating variants. Therefore, we recommend urgent monitoring and surveillance of the investigated mutations, as well as laboratory assessment of their pathogenicity and transmissibility.

Influence of COVID-19 on the poultry production and environment.

Although chickens are not susceptible to SARS-CoV-2, several coronavirus disease outbreaks have been described concerning poultry processing facilities in different countries. The COVID-19 pandemic and the developed strain caused 2nd, 3rd, and recent Indian strain waves of epidemics that have led to unexpected consequences, such as forced reductions in demands for some industries, transportation systems, employment, and businesses due to public confinement. Besides, poultry processing plants' conditions exacerbate the risks due to the proximity on the line, cold, and humidity. Most workers do not have access to paid sick time or adequate health care, and because of the low wages, they have limited reserves to enable them to leave steady employment. In addition, workers in meat and poultry slaughterhouses may be infected through respiratory droplets in the air and/or from touching dirty surfaces or objects such as workstations, break room tables, or tools. Egg prices have increased dramatically during the lockdown as consumers have started to change their behaviors and habits. The COVID pandemic might also substantially impact the international poultry trade over the next several months. This review will focus on the effect of COVID-19 on poultry production, environmental sustainability, and earth systems from different process points of view.

The mean severity score and its correlation with common computed tomography chest manifestations in Egyptian patients with COVID-2019 pneumonia

Background: Computed tomography (CT) is one of the main diagnostic tools for early detection and management of coronavirus disease 2019 (COVID-19) pneumonia. This study aims to highlight the commonly encountered CT findings in patients with COVID-19 pneumonia in Egypt and the mean severity score and its correlation with the imaging findings. This study involved 200 patients with pathologically confirmed COVID-19 infection;non-contrast CT chest was performed for all cases;in addition, CT findings and severity score (CT-SS) were then assessed using descriptive analysis, and the correlation between the CT findings and disease severity was assessed. Results: The ground-glass densities and peripheral adhesions were the most typical CT findings. Prominent interlobular septations;bronchial thickening/dilatation;CT signs of crazy-paving, halo, and reversed halo;and reactive mediastinal lymphadenopathy were significantly correlated with disease severity. The mean CT-SS of Egyptian patients with COVID-19 pneumonia was 11.2 (mild to moderate severity). Conclusion: Multislice CT played a vital role in the early identification of Egyptian patients with COVID-19 pneumonia. The assessment of the CT severity score of COVID-19 is essential for the extent of pneumonia involvement to help clinicians achieve the purpose of early diagnosis and accurate treatment. © 2020, The Author(s).

Challenges to the Poultry Industry: Current Perspectives and Strategic Future After the COVID-19 Outbreak.

Poultry immunity, health, and production are several factors that challenge the future growth of the poultry industry. Consumer confidence, product quality and safety, types of products, and the emergence and re-emergence of diseases will continue to be major challenges to the current situation and the strategic future of the industry. Foodborne and zoonotic diseases are strictly linked with poultry. Eradication, elimination, and/or control of foodborne and zoonotic pathogens present a major challenge to the poultry industry. In addition, the public health hazards from consuming foods with high antibiotic residues will remain a critical issue. The theory of poultry production described in this review will not be limited to considering disease control. Rather, it will also incorporate the interconnection of the animals' health, welfare, and immunity. It is essential to know that chickens are not susceptible to intranasal infection by the SARS-CoV-2 (COVID-19) virus. Nevertheless, the COVID-19 pandemic will affect poultry consumption, transport, and the economics of poultry farming. It will also take into consideration economic, ethical, social dimensions, and the sustenance of the accomplishment of high environmental security. Stockholders, veterinarians, farmers, and all the partners of the chain of poultry production need to be more involved in the current situation and the strategic future of the industry to fulfill human demands and ensure sustainable agriculture. Thus, the present review explores these important tasks.
