Custom-made 3D-printed face masks in case of pandemic crisis situations with a lack of commercially available FFP2/3 masks

In the case of pandemic crisis situations, a crucial lack of protective material such as protective face masks for healthcare professionals can occur. A proof of concept (PoC) and prototype are presented, demonstrating a reusable custom-made three-dimensionally (3D) printed face mask based on materials and techniques (3D imaging and 3D printing) with global availability. The individualized 3D protective face mask consists of two 3D-printed reusable polyamide composite components (a face mask and a filter membrane support) and two disposable components (a head fixation band and a filter membrane). Computer-aided design (CAD) was used to produce the reusable components of the 3D face mask based on individual facial scans, which were acquired using a new-generation smartphone with two cameras and a face scanning application. 3D modelling can easily be done by CAD designers worldwide with free download software. The disposable non-woven melt-blown filter membrane is globally available from industrial manufacturers producing FFP2/3 protective masks for painting, construction, agriculture, and the textile industry. Easily available Velcro fasteners were used as a disposable head fixation band. A cleaning and disinfection protocol is proposed. Leakage and virological testing of the reusable components of the 3D face mask, following one or several disinfection cycles, has not yet been performed and is essential prior to its use in real-life situations. This PoC should allow the reader to consider making and/or virologically testing the described custom-made 3D-printed face masks worldwide. The surface tessellation language (STL) format of the original virtual templates of the two reusable components described in this paper can be downloaded free of charge using the hyperlink (Supplementary Material online).     

Management of cancer patients during COVID-19 pandemic at developing countries

Cancer patient care requires a multi-disciplinary approach and multiple medical and ethical considerations. Clinical care during a pandemic health crisis requires prioritising the use of resources for patients with a greater chance of survival, especially in developing countries. The coronavirus disease 2019 crisis has generated new challenges given that cancer patients are normally not prioritised for admission in critical care units. Nevertheless, the development of new cancer drugs and novel adjuvant/neoadjuvant protocols has dramatically improved the prognosis of cancer patients, resulting in a more complex decision-making when prioritising intensive care in pandemic times. In this context, it is essential to establish an effective and transparent communication between the oncology team, critical care, and emergency units to make the best decisions, considering the principles of justice and charity. Concurrently, cancer treatment protocols must be adapted to prioritise according to oncologic response and prognosis. Communication technologies are powerful tools to optimise cancer care during pandemics, and we must adapt quickly to this new scenario of clinical care and teaching. In this new challenging pandemic scenario, multi-disciplinary work and effective communication between clinics, technology, science, and ethics is the key to optimising clinical care of cancer patients.     

Communicating to increase public uptake of pandemic flu vaccination in the UK: Which messages work?

BackgroundVaccination is considered the most effective preventive measure against influenza transmission, yet vaccination rates during the 2009/10 influenza A/H1N1 pandemic were low across the world, with the majority of people declining to receive the vaccine. Despite extensive research on the predictors of uptake of influenza vaccination, little research has focused on testing the effectiveness of evidence and theory-based messages.AimsTo examine the persuasiveness of messages promoting vaccination and antiviral use either as health-enhancing or as risk-reducing, as well as messages which conveyed evidence-based information about the costs and benefits of vaccination, or which applied anticipated regret as a motivator for vaccine uptake.MethodWe conducted 11 focus groups with forty-one members of the general population in England including young and older adults, those with lower education, parents, and those with elevated health risk. The data were analysed using thematic analysis.ResultsThe factual, evidence-based messages were well received with participants finding them the most convincing and useful, particularly where they gave cost–benefit comparisons. Health-enhancing messages were received with scepticism and concern that the messages were not honest about the potential lack of safety of vaccination. In contrast, risk-reduction messages were perceived as being more balanced and credible. Messages aiming to elicit feelings of anticipated regret for not getting vaccinated were generally perceived as patronising and unprofessional.ConclusionsVaccination messages should be kept brief, but convey balanced, evidence-based information, and be transparent in their communication of potential side-effects. The general public seem to prefer messages that are factual and emphasise the costs and benefits of vaccination, particularly with regards to vaccine safety.     

SARS-CoV-2-induced liver injury: A review article on the high-risk populations,manifestations, mechanisms,pathological changes,management, and outcomes

The novel coronavirus disease 2019 is an infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and was declared a global pandemic with more than 500 million reported cases and more than 6 million deaths worldwide to date. Although it has transitioned into the endemic phase in many countries, the mortality rate and overall prognosis of the disease are still abysmal and need further improvement. There has been evidence that shows the significance of SARS-CoV-2-related liver injury. Here, we review the literature on the various spectrum of SARS-CoV-2 infection-induced liver injury and the possible mechanisms of damage to the hepatobiliary system. This review aimed to illustrate the latest understanding regarding SARS-CoV-2-induced liver injury including the high-risk populations, the characteristic clinical manifestations, the possible pathogenic mechanism, the pathological changes, the current suggestions for clinical treatment for various spectrum of populations, and the prognosis of the condition. In conclusion, SARS-CoV-2 patients with a liver injury warrant close monitoring as it is associated with the more severe and poorer outcome of the infection.     

“They're trying to bribe you and taking away your freedoms”: COVID-19 vaccine hesitancy in communities with traditionally low vaccination rates

Vaccination is an essential public health intervention to control the COVID-19 pandemic. A minority of Canadians, however, remain hesitant about COVID-19 vaccines, while others outright refuse them. We conducted focus groups to gauge perceptions and attitudes towards COVID-19 vaccines in people who live in a region with historically low rates of childhood vaccination. Participants discussed their perception of COVID-19 vaccines and their intention to get vaccinated, and the low rate of COVID-19 vaccine uptake in Manitoba’s Southern Health Region compared to other regions in Canada. We identified three drivers of vaccine hesitancy: (1) risk perceptions about COVID-19 and the vaccines developed to protect against it, (2) religious and conservative views; and (3) distrust in government and science. Participant proposed recommendations for improving communication and uptake of the COVID-19 vaccines included: public health messages emphasising the benefits of vaccination; addressing the community’s specific concerns and dispelling misinformation; highlighting vaccine safety; and emphasising vaccination as a desirable behaviour from a religious perspective. Understanding the specific anxieties elicited by COVID-19 vaccines in areas with low childhood immunization rates can inform risk communication strategies tailored to increase vaccination in these specific regions. This study adds important information on potential reasons for vaccine hesitancy in areas with historically low rates of childhood vaccination, and provides important lessons learned for future emergencies in terms of vaccine hesitancy drivers and effective risk communication to increase vaccine uptake.     

Global health disparities in vulnerable populations of psychiatric patients during the COVID-19 pandemic

The coronavirus disease 2019 pandemic affects psychiatric patients disproportionately compared to the general population. In this narrative review, we examine the impact of the pandemic on significant global health disparities affecting vulnerable populations of psychiatric patients: People of diverse ethnic background and color, children with disabilities, sexual and gender minorities, pregnant women, mature adults, and those patients living in urban and rural communities. The identified disparities cause worsened mental health outcomes placing psychiatric patients at higher risk for depression, anxiety and posttraumatic stress disorder symptoms. Those psychiatric patients who are ethnic minorities display barriers to care, including collective trauma and structural racism. Sexual and gender minorities with mental illness face discrimination and limited access to treatment. Pregnant women with psychiatric diagnoses show higher exposure to domestic violence. Children with disabilities face a higher risk of worsening behavior. Mature adults with psychiatric problems show depression due to social isolation. Psychiatric patients who live in urban communities face pollutants and overcrowding compared to those living in rural communities, which face limited access to telehealth services. We suggest that social programs that decrease discrimination, enhance communal resilience, and help overcome systemic barriers of care should be developed to decrease global health disparities in vulnerable population.
