Non-evidenced based treatment: An unintended cause of morbidity and mortality related to COVID-19

Covid-19 cure perceptions and media use in India

BACKGROUND

During the early phases of Covid-19, social media platforms became a significant source of misinformation, and India emerged as a global hotspot. Studies show that 'miracle cure' for preventing and treating Covid-19 infection has been a prominent topic of misinformation. This study explores the extent to which beliefs in cure for Covid-19 in three prominent medical traditions popular in India are associated with the exposure to and trust in various sources from which the public access information.

METHODS

We conducted an online structured questionnaire survey of 500 respondents in August 2020 in four major cities of India.

RESULTS

Despite the scientific consensus at that time that there was no cure for Covid-19, close to three-quarters of our respondents believe that there was a cure in at least one of the three popular medical traditions in India: Allopathy, Homeopathy, and Ayurveda. We find that exposure to and trust in WhatsApp are associated with false beliefs regarding the existence of a cure for Covid-19 (p = 0.001 and p = 0.014, respectively). While trust in science is associated with correct beliefs (p = 0.025), there is evidence that trust in government information may foster incorrect beliefs (p = 0.031).

CONCLUSIONS

The high trust in scientific research and its potential ability to instill correct beliefs could be exploited to combat Covid-19 misinformation in India. Potential interventions such as awareness campaigns to increase digital media literacy, regulating social media platforms, and voluntary content regulation by social media platforms - might help policymakers tackle Covid-19 related misinformation effectively.

Market violence through destructive entrepreneurship: Assessing institutional responses to the proliferation of counterfeit traditional and alternative medicines in Ghana

Purpose

This multidisciplinary study seeks to determine the nature and structure of the informal markets for counterfeit medicines, the co-factors underpinning the demand and supply of counterfeit Western allopathic medicines (WAM), traditional and alternative medicines (TAM), and potential institutional responses in Ghana.

Method

This study is based on an interpretive research approach. It deploys a synthesis of a longitudinal ethnographic fieldwork, with multiple repeated visits for observations, analysis of documents, interviews, and focus group discussions.

Findings

The study identifies five major inter-related discoveries that point to the need for urgent institutional responses: Approaches to global health governance pay little attention to the complex economic gamut of TAM, including herbal medicines. The rise in necessity entrepreneurship and the availability of easy-to-use packaging and advertising technologies have made TAM a major competitor of WAM. The informal markets for WAM and TAM are structured in ways that allow them to evade formalized interventions and regulations. Standardization allows destructive entrepreneurs to derive advantage from economies of scale and reduce production costs, allowing the sector to flourish with little economic risk while inflicting violence on consumers. Personalization and co-creation of medicine with consumers has the added psychological effect of increasing consumer confidence. This, however, enlists consumers in the market violence against themselves.

Social implications

Destructive entrepreneurship, whether inadvertent or criminal creates benefits for groups and individuals but negatively affects public health on various levels.

Originality

Mitigation and interventions that ignore the informal TAM market of destructive entrepreneurship only answer a part of the big question of how to guarantee patient/consumer safety from the threats of all counterfeits.

Early detection of fraudulent COVID-19 products from Twitter chatter: a dataset and a baseline approach using anomaly detection (Preprint)

Background

Social media has served as a lucrative platform for spreading misinformation and for promoting fraudulent products for the treatment, testing, and prevention of COVID-19. This has resulted in the issuance of many warning letters by the US Food and Drug Administration (FDA). While social media continues to serve as the primary platform for the promotion of such fraudulent products, it also presents the opportunity to identify these products early by using effective social media mining methods.

Objective

Our objectives were to (1) create a data set of fraudulent COVID-19 products that can be used for future research and (2) propose a method using data from Twitter for automatically detecting heavily promoted COVID-19 products early.

Methods

We created a data set from FDA-issued warnings during the early months of the COVID-19 pandemic. We used natural language processing and time-series anomaly detection methods for automatically detecting fraudulent COVID-19 products early from Twitter. Our approach is based on the intuition that increases in the popularity of fraudulent products lead to corresponding anomalous increases in the volume of chatter regarding them. We compared the anomaly signal generation date for each product with the corresponding FDA letter issuance date. We also performed a brief manual analysis of chatter associated with 2 products to characterize their contents.

Results

FDA warning issue dates ranged from March 6, 2020, to June 22, 2021, and 44 key phrases representing fraudulent products were included. From 577,872,350 posts made between February 19 and December 31, 2020, which are all publicly available, our unsupervised approach detected 34 out of 44 (77.3%) signals about fraudulent products earlier than the FDA letter issuance dates, and an additional 6 (13.6%) within a week following the corresponding FDA letters. Content analysis revealed misinformation, information, political, and conspiracy theories to be prominent topics.

Conclusions

Our proposed method is simple, effective, easy to deploy, and does not require high-performance computing machinery unlike deep neural network-based methods. The method can be easily extended to other types of signal detection from social media data. The data set may be used for future research and the development of more advanced methods.

Upcoming and urgent challenges in critical care research based on COVID-19 pandemic experience

While the coronavirus disease 2019 (COVID-19) pandemic placed a heavy burden on healthcare systems worldwide, it also induced urgent mobilisation of research teams to develop treatments preventing or curing the disease and its consequences. It has, therefore, challenged critical care research to rapidly focus on specific fields while forcing critical care physicians to make difficult ethical decisions. This narrative review aims to summarise critical care research -from organisation to research fields- in this pandemic setting and to highlight opportunities to improve research efficiency in the future, based on what is learned from COVID-19. This pressure on research revealed, i.e., i/ the need to harmonise regulatory processes between countries, allowing simplified organisation of international research networks to improve their efficiency in answering large-scale questions; ii/ the importance of developing translational research from which therapeutic innovations can emerge; iii/ the need for improved triage and predictive scores to rationalise admission to the intensive care unit. In this context, key areas for future critical care research and better pandemic preparedness are artificial intelligence applied to healthcare, characterisation of long-term symptoms, and ethical considerations. Such collaborative research efforts should involve groups from both high and low-to-middle income countries to propose worldwide solutions. As a conclusion, stress tests on healthcare organisations should be viewed as opportunities to design new research frameworks and strategies. Worldwide availability of research networks ready to operate is essential to be prepared for next pandemics. Importantly, researchers and physicians should prioritise realistic and ethical goals for both clinical care and research.

Myths and misconception of COVID-19 among hospital sanitary workers in Pakistan: Efficacy of a training program intervention

Objective

Hospital sanitary workers are among the prime source to disseminate information at a massive level, however they received least attention during the pandemic COVID-19. The study was designed to investigate the prevailing myths and misconceptions of the coronavirus pandemic among the sanitary workers of health care system. Further, a systematic training program is devised and tested to demystify the false myths with discerning truth and awareness-raising in hospital sanitary workers.

Method

A pre-post face-to-face intervention design was opted and the intervention was conducted at five locations by the project team. The intervention consisted a 3 days training program to target myths and misconceptions of hospital sanitary workers. The study was completed in 8 months starting from August, 2019 to March, 2020. Participants were recruited from local hospitals having a specialized indoor COVID treatment facility. The sample consisted of 82 participants (n = 25, 30.09% females) with age ranging from 18 to 60 years (M ± SD = 37.41 ± 10.09).

Findings

The results indicated that 86.4% of the participants never heard the name of the coronavirus before the pandemic in Pakistan. A majority of the participants (> 50%) believed on a very alarming but unrealistic rate of mortality i.e., 30–60%. The pre-testing showed a high prevalence of myths in all four domains (i.e., popular treatments = 24.44, conspiracy myths = 7.93, home remedies = 16.46, and COVID-reliance = 7.82). The pre and post comparison of individual myths showed significant improvement on 24 of the 26 myths with a decline ranging from 0.18 to 1.63. Overall, the intervention significantly decreased scores on all four domains of coronavirus myths.

Conclusion

The training intervention appeared to effectively reduce myths and misconceptions of sanitary staff workers and is advised to be included as a standard training program for sanitary workers of health care system.

Attitudes of Chinese immigrants in Canada towards the use of Traditional Chinese Medicine for prevention and management of COVID-19: a cross-sectional survey during the early stages of the pandemic

OBJECTION

The objective of this study was to assess attitudes towards the use of Traditional Chinese Medicine (TCM) for COVID-19 among Chinese immigrants in Canada during the early stage of the COVID-19 pandemic.

METHODS

A cross-sectional study was conducted in April 2020 in Canada. Individuals aged 16 or older who were of Chinese origin and living in Canada at the time of the survey were invited to participate in an online survey. Descriptive and univariate statistics were performed to describe participant attitudes towards various preventive and treatment measures for COVID-19. Multiple logistic regression was used to identify independent associations with sociodemographic factors and attitudes.

RESULTS

A total of 754 eligible respondents were included in the analysis. 65.8% of the participants were female, 77.2% had a university degree or higher and 28.6% were 55 years of age or older. Overall, 48.8% of the study participants believed that TCM was effective in preventing COVID-19% and 46.2% would use TCM if they had COVID-19-related symptoms. However, the corresponding numbers for western medicine were 20.8% and 39.9%, which were statistically lower (p<0.01). Older participants (55+vs <35, OR=3.55 (95% CI 2.05 to 6.14); 35-54 vs <35, OR=1.98 (95% CI 1.27 to 3.08)) and those who were dissatisfied with their income (OR=2.47(95% CI 1.56 to 3.92)) were more likely to believe TCM was effective against COVID-19. Similarly, older participants (55+vs <35, OR=3.13 (95% CI 1.79 to 5.46); 35-54 vs <35, OR=2.25 (95% CI 1.35 to 3.74)), females (OR=1.60 (95% CI 1.15 to 2.23)), and those born in mainland China (OR=10.49 (95% CI 2.32 to 47.39)) were more likely to use TCM if they had symptoms of COVID-19.

CONCLUSION

Despite the lack of scientific evidence to support its use, TCM was widely believed by Chinese immigrants in Canada to be an effective means of preventing COVID-19 and many also stated they would use it if they were experiencing symptoms of COVID-19.

An Overview of the Pathogenesis, Transmission, Diagnosis, and Management of Endemic Human Coronaviruses: A Reflection on the Past and Present Episodes and Possible Future Outbreaks

The outbreak of the 2019 coronavirus pandemic caught the world by surprise in late 2019 and has held it hostage for months with an increasing number of infections and deaths. Although coronavirus was first discovered in the 1960s and was known to cause respiratory infection in humans, no information was available about the epidemic pattern of the virus until the past two decades. This review addresses the pathogenesis, transmission dynamics, diagnosis, management strategies, the pattern of the past and present events, and the possibility of future outbreaks of the endemic human coronaviruses. Several studies have described bats as presumptive natural reservoirs of coronaviruses. In essence, the identification of a diverse group of similar SARS coronaviruses in bats suggests the possibility of a future epidemic due to severe acute respiratory syndrome (SARS-like) coronaviruses originating from different reservoir hosts. The study also identified a lack of vaccines to prevent human coronavirus infections in humans in the past, however, the recent breakthrough in vaccine discovery and approval for emergency use for the treatment of Severe Acute Respiratory Syndrome Coronavirus 2 is commendable. The high rates of genomic substitution and recombination due to errors in RNA replication and the potential for independent species crossing suggest the chances of an entirely new strain evolving. Therefore, rapid research efforts should be deployed for vaccination to combat the COVID-19 pandemic and prevent a possible future outbreak. More sensitization and enlightenment on the need to adopt good personal hygiene practices, social distancing, and scientific evaluation of existing medications with promising antiviral effects against SARS-CoV-2 is required. In addition, intensive investigations to unravel and validate the possible reservoirs, the intermediate host, as well as insight into the ability of the virus to break the species barrier are needed to prevent future viral spillover and possible outbreaks.

Systematic Delineation of Media Polarity on COVID-19 Vaccines in Africa: Computational Linguistic Modeling Study

BACKGROUND

The global onset of COVID-19 has resulted in substantial public health and socioeconomic impacts. An immediate medical breakthrough is needed. However, parallel to the emergence of the COVID-19 pandemic is the proliferation of information regarding the pandemic, which, if uncontrolled, cannot only mislead the public but also hinder the concerted efforts of relevant stakeholders in mitigating the effect of this pandemic. It is known that media communications can affect public perception and attitude toward medical treatment, vaccination, or subject matter, particularly when the population has limited knowledge on the subject.

OBJECTIVE

This study attempts to systematically scrutinize media communications (Google News headlines or snippets and Twitter posts) to understand the prevailing sentiments regarding COVID-19 vaccines in Africa.

METHODS

A total of 637 Twitter posts and 569 Google News headlines or descriptions, retrieved between February 2 and May 5, 2020, were analyzed using three standard computational linguistics models (ie, TextBlob, Valence Aware Dictionary and Sentiment Reasoner, and Word2Vec combined with a bidirectional long short-term memory neural network).

RESULTS

Our findings revealed that, contrary to general perceptions, Google News headlines or snippets and Twitter posts within the stated period were generally passive or positive toward COVID-19 vaccines in Africa. It was possible to understand these patterns in light of increasingly sustained efforts by various media and health actors in ensuring the availability of factual information about the pandemic.

CONCLUSIONS

This type of analysis could contribute to understanding predominant polarities and associated potential attitudinal inclinations. Such knowledge could be critical in informing relevant public health and media engagement policies.

Public health decisions in the COVID-19 pandemic require more than 'follow the science'

Although empirical evidence may provide a much desired sense of certainty amidst a pandemic characterised by uncertainty, the vast gamut of available COVID-19 data, including misinformation, has instead increased confusion and distrust in authorities' decisions. One key lesson we have been gradually learning from the COVID-19 pandemic is that the availability of empirical data and scientific evidence alone do not automatically lead to good decisions. Good decision-making in public health policy, this paper argues, does depend on the availability of reliable data and rigorous analyses, but depends above all on sound ethical reasoning that ascribes value and normative judgement to empirical facts.

Mental health consequences of COVID-19 media coverage: the need for effective crisis communication practices

During global pandemics, such as coronavirus disease 2019 (COVID-19), crisis communication is indispensable in dispelling fears, uncertainty, and unifying individuals worldwide in a collective fight against health threats. Inadequate crisis communication can bring dire personal and economic consequences. Mounting research shows that seemingly endless newsfeeds related to COVID-19 infection and death rates could considerably increase the risk of mental health problems. Unfortunately, media reports that include infodemics regarding the influence of COVID-19 on mental health may be a source of the adverse psychological effects on individuals. Owing partially to insufficient crisis communication practices, media and news organizations across the globe have played minimal roles in battling COVID-19 infodemics. Common refrains include raging QAnon conspiracies, a false and misleading "Chinese virus" narrative, and the use of disinfectants to "cure" COVID-19. With the potential to deteriorate mental health, infodemics fueled by a kaleidoscopic range of misinformation can be dangerous. Unfortunately, there is a shortage of research on how to improve crisis communication across media and news organization channels. This paper identifies ways that legacy media reports on COVID-19 and how social media-based infodemics can result in mental health concerns. This paper discusses possible crisis communication solutions that media and news organizations can adopt to mitigate the negative influences of COVID-19 related news on mental health. Emphasizing the need for global media entities to forge a fact-based, person-centered, and collaborative response to COVID-19 reporting, this paper encourages media resources to focus on the core issue of how to slow or stop COVID-19 transmission effectively.

Antiseptic drugs and disinfectants with special scrutiny of COVID-19 pandemic related side effects

This review covers publications during the period of January 2020 to December 2020 on adverse reactions to antiseptic drugs and disinfectants. Specific agents discussed are alcohols (ethanol, isopropanol), aldehydes (formaldehyde), guanidines (chlorhexidine, polyhexamethylene guanidine, and polyhexamethylene biguanidine), benzalkonium compounds, triclocarban, povidone-iodine, and sodium hypochlorite. No new data were identified for glutaraldehyde, cetrimide, ethylene oxide, tosylchloramide, triclosan, iodine, and phenolic compounds. The use of antiseptic drugs and disinfectants has been considerably increased during 2020 in a variety of medical and occupational settings, in commerce and gastronomy, as well as in the household, due to their antiviral properties against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the Coronavirus Disease 2019 (COVID-19) pandemic. Exposure was additionally increased by widespread misinformation on social media for non-evidence based disinfectant use, even including ingestion or injection, as well as by questionable practices such as environmental spraying or disinfectant gates. Irritant effects on the respiratory system, skin and eyes were the most common adverse reaction, while the widespread and sometimes excessive use led to increased reports of poisonings, as well as cases of disinfectant adulteration including dilution into ineffective concentrations or addition of toxic agents such as methanol.

SARS-CoV-2 pharmacologic therapies and their safety/effectiveness according to level of evidence

INTRODUCTION

There is a pressing need for COVID-19 transmission control and effective treatments. We aim to evaluate the safety and effectiveness of SARS-CoV-2 pharmacologic therapies as of August 2, 2020 according to study level of evidence.

METHODS

PubMed, ScienceDirect, Cochrane Library, JAMA Network and PNAS were searched. The following keywords were used: ((COVID-19) OR (SARS-CoV-2)) AND ((((((therapeutics) OR (treatment)) OR (vaccine)) OR (hydroxychloroquine)) OR (antiviral)) OR (prognosis)). Results included peer-reviewed studies published in English.

RESULTS

15 peer-reviewed articles met study inclusion criteria, of which 14 were RCTs and one was a systematic review with meta-analysis. The following pharmacologic therapies were evaluated: chloroquine (CQ), hydroxychloroquine (HCQ), antivirals therapies, plasma therapy, anti-inflammatories, and a vaccine.

CONCLUSION

According to level 1 evidence reviewed here, the most effective SARS-Co-V-2 pharmacologic treatments include remdesivir for mild to severe disease, and a triple regimen therapy consisting of lopinavir-ritonavir, ribavirin and interferon beta-1b for mild to moderate disease. Also, dexamethasone significantly reduced mortality in those requiring respiratory support. However, there is still a great need for detailed level 1 evidence on pharmacologic therapies.

Rapid in vitro assays for screening neutralizing antibodies and antivirals against SARS-CoV-2

•

We have developed a rapid, accurate, and highly reproducible plaque reduction microneutralization (PRMNT) assay for SARS-CoV-2.

•

Our PRMNT assay allows to identify and characterize antibodies with neutralizing activity against SARS-CoV-2.

•

Likewise, our PRMNT assay can be used to find compounds with antiviral activity against SARS-CoV-2.

•

The PRMNT assay can be developed using peroxidase or infrared staining readouts.

•

Our PRMNT assay can be adapted to HTS settings to interrogate complex library of SARS-CoV-2 inhibitors.

Towards the end of 2019, a novel coronavirus (CoV) named severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), genetically similar to severe acute respiratory syndrome coronavirus (SARS-CoV), emerged in Wuhan, Hubei province of China, and has been responsible for coronavirus disease 2019 (COVID-19) in humans. Since its first report, SARS-CoV-2 has resulted in a global pandemic, with over 10 million human infections and over 560,000 deaths reported worldwide at the end of June 2020. Currently, there are no United States (US) Food and Drug Administration (FDA)-approved vaccines and/or antivirals licensed against SARS-CoV-2. The high economical and health impacts of SARS-CoV-2 has placed global pressure on the scientific community to identify effective prophylactic and therapeutic treatments for SARS-CoV-2 infection and associated COVID-19 disease. While some compounds have been already reported to reduce SARS-CoV-2 infection and a handful of monoclonal antibodies (mAbs) have been described that neutralize SARS-CoV-2, there is an urgent need for the development and standardization of assays which can be used in high through-put screening (HTS) settings to identify new antivirals and/or neutralizing mAbs against SARS-CoV-2. Here, we described a rapid, accurate, and highly reproducible plaque reduction microneutralization (PRMNT) assay that can be quickly adapted for the identification and characterization of both neutralizing mAbs and antivirals against SARS-CoV-2. Importantly, our MNA is compatible with HTS settings to interrogate large and/or complex libraries of mAbs and/or antivirals to identify those with neutralizing and/or antiviral activity, respectively, against SARS-CoV-2.
