ABSTRACT

Objective: To share the epidemiological, clinical and laboratory -based evidence of severe acute respiratory syndrome Corona Virus-2 with focus on the cases of re-infection;an update after one year of the ongoing pandemic. Study Design: Prospective observational study. Place and Duration of Study: Department of Pathology, in collaboration with Department of Medicine, Combined Military Hospital, Malir, from Mar 2020 to Feb 2021. Methodology: Total 5190 nasopharyngeal swabs were collected and transported to the laboratory in viral transport media for severe acute respiratory syndrome Corona Virus-2, from all symptomatic patients with a history of exposure/traveling from endemic areas and those requiring admission in hospital and were screened for COVID-19 as per hospital standing protocols. Results: 561(10.8%) patients were PCR positive for severe acute respiratory syndrome Corona Virus-2. The mean age of patients was 39.45±31.9 years and a majority of patients were males 426 (76%). The most common symptoms were fever and dry cough followed by myalgia and shortness of breath. 37 (9%) patients died due to the severity of the illness. Total 6 (1.46%) cases of laboratory-confirmed reinfection of severe acute respiratory syndrome Corona Virus-2 were reported. 2(33%) cases of reinfection were observed in health care workers, mortality was seen in a single patient associated with old age and comorbidities. Conclusion: In our study, the severity of the disease was directly related to the age of patients and underlying comorbidities. Reinfection was associated with increased viral load and exposure to the infected environment. © 2022, Army Medical College. All rights reserved.

ABSTRACT

Objective: To ascertain the immunogenicity and short-term safety of inactivated SARS-CoV-2 Vaccine (Vero Cell), BBIBP-CorV (Sinopharm) in our setup. Study Design: Cross-sectional study. Place and Duration of Study: Combined Military Hospital Sialkot Pakistan, from Feb to Apr 2021. Methodology: A total of 227 health care workers (HCWs) between 18 to 59 years of age were included in the study. Two doses of Inactivated SARS-CoV-2 Vaccine (Vero Cell), BBIBP-CorV were administered to all individuals 21 days apart and they were monitored for any vaccine-related adverse reactions for 7 days after each dose. Neutralizing antibodies (NAbs) in study subjects were detected in three samples i.e. before 1st dose of vaccine, 21 days after 1st dose and 14 days after 2nd dose by Elecsys Anti- SARS-CoV-2 S (Roche Diagnostics). Results: Mean age of individuals in the study was 36.70 ± 18.08 years and most individuals were in the 31-45 years age group. Fatigue and drowsiness were the most common adverse effects experienced by study subjects after 1st and 2nd dose of the vaccine followed by malaise and headache. Only 42 (39%) individuals developed positive neutralizing antibody titers in a sample taken 21 days after 1st dose while all individuals except one (99%) developed positive neutralizing antibody titers in a sample taken 2 weeks after 2nd vaccine dose. Conclusion: Inactivated SARS-CoV-2 Vaccine (Vero Cell), BBIBP-CorV is safe and well-tolerated with very few adverse reactions. Immunogenicity was well achieved as the seroconversion rate was 99% two weeks after 2nd dose of the vaccine. © 2021, Army Medical College. All rights reserved.

ABSTRACT

The article is devoted to revealing the peculiarities of the perception of the pandemic in Ukraine, the causes and exacerbation of social problems in this regard. In order to identify the causal links between them in the spheres of human activity in society, the role and place in solving this problem of public associations, including academic formations, has been determined. Four main scenarios for the spread of coronavirus in different regions of the world are mentioned. Observations of the disease development are given. Measures to prevent the spread of the virus have been proposed. Data on the first outbreaks of coronavirus in the world are given. The lack of state control and accountability mechanisms is noted. The role of the pandemic, which has led to serious global socio-economic consequences, the postponement or cancellation of sporting, religious and cultural events and the spread of fears of shortages in the supply of various goods and products, which in some regions caused panic shopping is outlined. Emphasis is placed on the problem that arises when creating specialized medical institutions that successfully take root and operate on a European basis. It is noted that acute social problems, including a pandemic, are the basis of political instability and unrest in the state;insufficient anti-pandemic living conditions make it impossible to implement preventive measures, full vaccination of citizens, strengthening democratic governance and civil society institutions. On the example of the Academy of Economic Sciences of Ukraine of the National Academy of Science of Higher Education of Ukraine and the Academy of Social Management, a strategy for solving this humanitarian problem in the future is proposed. The main directions of solving pandemic problems in Ukraine in the near future are outlined.

ABSTRACT

The various social restrictions imposed to contain the spread of COVID-19 virus have brought unprecedented disruptions in people's lifestyle. The academic institutions were caught unprepared and had to adjust abruptly. With this, we assessed how working adults in a state university in rural Philippines are coping with the disruptions brought by the pandemic. We conducted a cross-sectional online survey on May 18 to 23, 2020 where 133 working adults from the Visayas State University, Leyte, Philippines responded to the survey. Results show that the top most rank coping mechanism for both men and women is doing household chores. Results further suggest that men are more inclined to surfing the net and use social media while women focus more on praying and gardening. Pets are considered as an important companion to cope better with the pandemic. Our results highlight differences in coping mechanisms between working men and women in dealing with the pandemic. Empirical findings suggest that working adults with diversified activities and engaged more in physical activities such as household chores and gardening tend to cope better during lockdowns. In addition, income and access to internet are significant determinants of coping mechanisms. Policy makers and administrators in state university in Philippines may benefit from understanding gender differences in coping with the pandemic and can tailor approaches that may contribute to wellbeing issues among working adults.

ABSTRACT

The COVID-19 pandemic highlighted limitations in the current public health data infrastructure, and the need for a comprehensive, real-time, centralized, user-friendly data management system suitable for both disease surveillance and outbreak management. To address these issues, the Canadian Forces Health Services Group developed the web-based Canadian Armed Forces Surveillance and Outbreak Management System (CAF SOMS). This paper details the development of the CAF SOMS, provides formative evaluation results and includes a discussion of the lessons learned and intent to use the CAF SOMS in future to enhance the CAF's disease surveillance and outbreak management capability beyond COVID-19.

ABSTRACT

We examine an assumed link between reducing inequality in income distribution, namely reducing the Gini coefficient on one hand, and improving public health in general and lowering the incidence and severity of COVID-19 in particular on the other hand. The Gini coefficient can be shown to consist of two components, one of which is (a measure of) relative deprivation, which was found to cause social stress that harms public health. Because a component is not the whole, the lowering of inequality in the income distribution by means of reducing the Gini coefficient does not necessarily result in lowering relative deprivation. Specifically, we show that a policy of reducing income inequality aimed at improving public health might not be effective - even when, in the process, no-one's income is reduced, or all incomes increase.

ABSTRACT

Patients have developed a well-informed sense of validation concerning maintaining hygiene standards. The pandemic, somehow in disguise, presented the valuable perspective of life reflection and gratitude. The attitude of a majority of patients engaged was immensely that of a deep reflection of the privilege of having access to early diagnosis, treatment, and adequate support. However, the complaints of the past, knowing that they are alive and have hope to keep fighting on with gratitude and sense of acceptance. However, they wished that the experience of the social media - health engagement platform should continue as it provided a good level of the bridge of gap of information. The cost of treatment remains a major concern as it largely translates to possible dropout from treatment courses for most cancer patients who can't afford the current cost. The concerns of the cancer patients and survivors during and after the covid-19 pandemic are similarly a concern to public health professionals worldwide. The need to aid their return to routine health care services is more important and therefore requires an urgent reorganization of cancer management services. An urgent intervention should be focused on patient re-orientation /pandemic control, staff training and retraining, awareness campaign, screening and result accessibility, special pandemic services, amongst others. The outcome reflected a very huge level of poor cancer patient experience in the public cancer treatment centres, while the reverse is the case with the private cancer treatment centres. This can be managed if an urgent intervention as proffered is implemented.

ABSTRACT

This is a critical appraisal of a manuscript outlining additional indicators used in the United States to augment traditional disease surveillance tools. The article went through the peer-review process. Therefore, it may be considered as objective and unbiased. The structure of the article is coherent, and it was published in a journal for digital medicine, health, and health care in the internet age. The article has contributed to the literature and provides a basis for strengthening existing surveillance systems to improve public health outcomes. However, it is suggested that whenever new indicators are being developed, their essential components must be fully defined.

ABSTRACT

The COVID-19 caused by novel single-stranded RNA enveloped severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) first appeared in Wuhan, China. A lot of focus has been given to pulmonary complications. According to several case reports, cardiovascular associated clinical manifestations include myocarditis, arrhythmias, veno-thromboembolic events, acute coronary syndrome (ACS), and pericarditis. Different modalities in diagnosis like 2D, doppler can help in the early diagnosis of right ventricular function. This study evaluates the cardiac changes in recovered COVID-19 positive patients by 2D echocardiogram and other modalities. In this prospective observational study, 139 participants recently recovered from COVID-19 illness were identified and recruited after obtaining the Informed concerned form (ICF). The patients once enrolled were subjected to 2D echo and ECG as part of routine clinical practice. Out of 139 patients, 89 (64.03%) were males, and the rest were females. Based on the severity scale, 13 (9.35%) participants had suffered a severe form of COVID-19 infection. Right ventricular functional assessment, right ventricular global strain (RVGLS) was abnormal in 72 (51.80%) participants. Arrhythmias were reported in 31 (22.30%) participants;among them, 30 participants had sinus bradycardia. Our study demonstrates the association between COVID-19 and cardiac changes/ incidence of cardiovascular complications in recovered COVID-19 patients. This study provides first-hand evidence of the incidence of abnormal LVGLS and RVGLS in COVID-19 recovered patients. In addition, there was a higher incidence of arrythmias.

ABSTRACT

The desire to control Covid 19 pandemic has continued to exist in the Mbala district of Zambia, with the latest trend showing a significant increase in a number of people testing positive, with a corresponding increase in vaccines (AZ, JJ) hesitancy resulting in a low (2.8%) vaccination rate in the district. Thus, the need to probe further on covert factors under acceptability (myths, AEFs) and accessibility (vaccines availability, adequacy of vaccination sites) that could be reducing Covid 19 vaccine uptake in Mbala district. The study used a cross-sectional survey, a mixed (quantitative & qualitative) method in eliciting information from data sources covering a period of six months (April - September 2021). In all, 341 research respondents were interviewed through self-administered questionnaires. Data were analysed using descriptive statistics and binary logistic regression under SPSS v16. Study Findings Provide Sufficient Evidence That High Myth (89.8%) Reduced Acceptability Levels, While A Low Number Of Vaccination Sites (59%) Reduced Accessibility, Resulting In A Low Uptake Rate In Mbala District. Therefore, The Study Recommended;Building Up Of Well-Financed District Covid 19 Task Forces With Educational Aims On Acceptability And Accessibility, Governments To Introduce Specific Funding Lines For Covid 19 Vaccination Campaign And Enshrine It Into Monthly Grants For Routine-Outreach Covid 19 Vaccination Services, And Local Governments Through The Directorate Of Public Health To Introduce By-Laws On Mandatory Covid 19 Vaccination Passports For The Public. With Proper Implementation Of All These Study Recommendations, Covid 19 Vaccination Coverage Rates Can Increase Drastically Across All Districts Of Northern Zambia.

ABSTRACT

Pharmacies are the frontline of the pandemic and critical to maintaining public health. The emergence of COVID-19 brought unprecedented challenges and changes to all nations of the world. In the light of this, this study assessed the challenges of pharmaceutical practices in Nigeria during COVID-19. A descriptive cross-sectional survey design was adopted, and the data were collected from 1,200 respondents through the interview schedule and structured questionnaire using a systematic random sampling technique. A total of 1,118 copies of the questionnaire were retrieved, coded, and analysed using descriptive and inferential statistics aided by the SPSS software version 23. The study discovered different factors that influenced the effective practice of pharmacists during the COVID-19 pandemic. The findings of this study revealed that the majority, 591(52.9%) of the pharmacists, encountered difficulties on the road with security personnel while on essential duty and also found it 'somewhat difficult to work during the pandemic. The results of Factor Analysis grouped the major challenges into material and financial constraints. The results showed two orthogonal factors pharmaceutical practices, which were derived with the total explanation of 65.35% of the variance. Only variables with constraints loadings of 0.70 and above were used in naming the constraints. The material constraint has the greatest impact on effective practices of pharmacists to provide treatment for illnesses during COVID-19 with a 44.16% contribution. There is a need for government and institution supports for better and effective pharmaceutical practices before, during, and after any sort of pandemic, especially in drugs supplies and financial assistance.

ABSTRACT

As the pandemic was sudden and no time was given to prepare for the lockdown measure, pharmaceutical practices were significantly disrupted in the aspects of manufacturing and supplying drugs, sales, and profit-making. Therefore, this study assessed the impacts of COVID-19 crisis on pharmaceutical practices in Nigeria. A descriptive cross-sectional design survey was adopted to draw information from the pharmacists (respondents) among the targeted population. 1,200 professional and practice pharmacists were systematically and randomly selected across the six geopolitical zones in Nigeria, while 1,118 copies of the administered questionnaire were retrieved, coded, and analyzed using descriptive and inferential statistics aided by the Statistical Package for Social Sciences (SPSS) software version 23 to run the analyses. The findings showed that COVID-19 had negative impacts on pharmaceutical practices, especially in hospital and community practices. A 25%-49% decrease was highly indicated in sales, purchase orders, and profits, while the majority, 347 (31.04%) of the respondents, indicated that they had a 1%-24% decrease in their workforce. Also, total lockdown as a COVID-19 measure increased the level of insecurity and inflation during the pandemic. 75.13% of the pharmacists who represent the targeted population indicated that their place of work largely enforced COVID-19 basic preventive measures during the pandemic. This study concludes that necessary efforts should be put in place to ease the affairs of the pharmaceutical practices before, during, and after the pandemic.

ABSTRACT

The patho-physiology of COVID19 is still not clear. This study investigated the status of coagulation, LDH activity, and inflammation in SARS-CoV-2 infected patients. One hundred and thirty-four newly diagnosed COVID19 infected patients (age ranged 65-82 years) attending Mullingar Regional Hospital, Mullingar, Republic of Ireland, volunteered to participate in this study. They all presented with a pulmonary disorder, pyrexia, vomiting, body pains, etc. SARS-CoV-2 confirmatory test was done with RT-PCR molecular test using Cepheid Genexpert System. The data of another 121 plasma samples of apparently normal, non-COVID19 infected individuals taken before the emergence of COVID19 served as controls. Levels of blood platelets was determined in the participants using Siemen ADVIA 2120 Haematological System, and plasma D-dimer was determined in the participants using Star Max-Stago-Automatic Coagulation Analyzer LDH activity, plasma ferritin, and C-reactive protein (CRP) were determined in the participants using Beckman AU680-Chemistry Analyser. SARS-CoV-2 -infected patients showed significantly (p< 0.001) higher levels of D-dimer (1522.95+1395.45 ng/ml), CRP (125.3+116.4 mg/l), ferritin (488.5+514.9pg/l), and LDH activity (574.4+446.7iu/l) compared to controls (78.8+18.1 ng/ml, 2.4+1.7 mg/l, 61.3+58.2pg/l, 304.1+76.6iu/l respectively). The blood platelet count did not show significant (p>0.05) change in the COVID19 patients (252.2 x 109+101 x 109) compared to controls (256.4 x 109+63.2 x 109). Elevated LDH activity could indicate tissue breakdown in the SARS-Cov-2 infected patients. Hyper-coagulation and inflammation are imminent in the COVID19 patients. Adjuvant anticoagulant and anti-inflammatory therapies may be useful as part of therapeutic regimen in the SARS-CoV-2 infected patients.

ABSTRACT

Globally, coronavirus disease (COVID-19) is a major public health problem due to its high virulence associated with communities spreading with no definitive treatment and untimely death. Various perceptions have been associated with the COVID-19 pandemic. This study assessed the perception of mitigating strategies and its challenges regarding COVID-19 among residents in Ogun State, Nigeria. A descriptive cross-sectional study design using a multi-stage sampling technique was used to solicit information from 2400 respondents in Ogun State, Nigeria. Data were collected using an interviewer-administered questionnaire from 4th to 15th October 2020. Descriptive statistics were employed for data analysis. Findings of this study revealed that avoidance of social gathering (23.5%), the use of face masks (23.3%), and cleaning of hands with sanitizer (22.7) were the most common mitigation strategies adopted by the respondents in the study area, although full adherence was low. The most strategies to prevent the transmission of COVID-19 were suggested by the respondents. These strategies included regular quarantining affected person(s), practicing basic measures, and going to the hospital with 21.5%, 20.6%, and 19.7% respectively. The results also showed that going to Churches and Mosques, inconvenient time of using face masks and restriction from social gathering and clubbing during COVID-19 pandemic were the most challenges faced in the study area. This study concludes that there should be more provision of medical supplies and palliatives for individuals, health education, the enforcement of preventive measures, and free testing and treatment should receive much recognition.

ABSTRACT

Due to unprecedented threat to the economy and the quality of life caused by the COVID-19 pandemic, this study focused on cost-benefit analysis during the lockdown of COVID-19 and the health belief model of COVID-19 pandemic in Ogun State, Nigeria. A total of 2400 copies of the questionnaire were administered to solicit information from the respondents using systematic random sampling technique on the targeted population while 2363 copies were retrieved and analyzed using descriptive statistics. The findings of the study revealed that the lockdown had negative impacts on health, economic, and social impacts. Results showed that 50.7% of the respondents spent no time going to the market and/or work during COVID-19, and this made 81.9% of them unable to gain extra gain during the lockdown as they were completely restricted for activities. The lockdown had impacts on socioeconomic activities as the prices of consumable goods increased due to the low supply. 71.8% of the respondents indicated that the government did not provide palliative measures for the households. The results further showed that everyone could be infected with COVID-19 as 86.0% of respondents indicated. 48% revealed that COVID-19 drugs were unavailable and prayers from religious leaders could not cure COVID-19. Besides, 65.5% were able to follow the basic measures put in place to reduce the spread of COVID-19 in the study area. This study concluded that necessary things should be put in place to ease the affairs of the populace before any other lockdown measure is made.

ABSTRACT

Since its outbreak in late 2019, Coronavirus Disease 2019 (COVID-19) has been ravaging the health system of most countries of the world. Although many preventive and treatment strategies have been proposed and implemented to combat the disease, these efforts seem to be insufficient, and in some cases ineffective. This is evident by the daily rising global incidence and case fatality of the COVID-19 pandemic. A situation if not mitigated early will likely crumble the global economy and tilt the world to an unprecedented global recession. This challenge demands that researchers and clinicians ask more in-depth questions about the novel coronavirus disease. Aside from age that has been confirmed to be linearly associated, what are the other possible socio-demographic and lifestyle-related risk factors that may be associated with COVID-19?What are the possible factors or comorbid conditions that may worsen clinical progression and determine the clinical outcome in confirmed COVID-19 cases? Does the pre-, peri-, or post-morbid lifestyle choices of people have an impact on COVID-19 preventive and treatment efforts? And how can we use the knowledge of the associated risk factors, comorbid conditions, and lifestyle choices of people to improve preventive efforts and clinical management of COVID-19? Answer to these questions may likely serve as an important guide for policymakers and clinicians in their design and implementation of COVID-19 targeted preventive and treatment policies and programs, especially in Low- and Middle-Income Countries (LMICs). The purpose of this article is to critically review available literature and provide evidence-based recommendations.

ABSTRACT

During the ongoing global COVID-19 pandemic, the number of cases continues to increase and leads to a surge of patients who need treatment. However, many hospitals are not ready to deal with this type of emergency. This study aimed to review previous studies on Hospital preparedness in facing COVID-19 disaster. This is a Systematic Literature Review on articles collected from 4 databases, i.e., PubMed, Science Direct, Google Scholar, and Crossref by applying the inclusion criterion of articles published in English and Indonesian on qualitative and quantitative studies related to hospital preparedness. PRISMA Guideline was used for this review. Based on the application of the inclusion criterion, eight articles were considered to be appropriate for the review. Three of these articles presented good hospital preparedness, while the other five demonstrated the presence of gaps in terms of facilities, staff training, and coordination. The instruments used in the study presented in these articles were adapted from CDC and WHO and were modified to adjust them with the local condition. A comprehensive assessment on hospital preparedness is needed. Health care worker training is an important step in hospital preparedness.

ABSTRACT

In 2019, the Canadian Government released a national dementia strategy that identified the need to address the health inequity (e.g., avoidable, unfair, and unjust differences in health outcomes) and improve the human rights of people living with dementia. However, the novel coronavirus disease 2019 (COVID-19) pandemic is having an inequitable impact on people with dementia in terms of mortality and human rights violations. As the new Omicron COVID-19 variant approaches its peak, our commentary highlights the need for urgent action to support people living with dementia and their care partners. More specifically, we argue that reducing COVID-19 inequities requires addressing underlying population-level factors known as the social determinants of health. Health disparities cannot be rectified merely by looking at mortality rates of people with dementia. Thus, we believe that improving the COVID-19 outcomes of people with dementia requires addressing key determinants such as where people live, their social supports, and having equitable access to healthcare services. Drawing on Canadian-based examples, we conclude that COVID-19 policy responses to the pandemic must be informed by evidence-informed research and collaborative partnerships that embrace the lived experience of diverse people living with dementia and their care partners.
