Confirmation of Safety of COVID 19 mRNA Vaccination for Cancer Patientsijtsrd
Patients in the active phase of treatment for cancer are a population at risk of coronavirus disease 19 COVID 19 with poor prognosis. While a majority of patients treated for cancer expressed their will to be vaccinated as early as December 2020 in a French survey, no data were available in terms of vaccine efficacy and tolerance, because they were excluded from initial registration trials. Several clinical facilities aimed to assess the safety and immunogenicity of the BNT162b2 Pfizer–BioNTech vaccine in patients with cancer. In patients with cancer, one dose of the BNT162b2 vaccine yields poor efficacy. Immunogenicity increased significantly in patients with solid cancer within 2 weeks of a vaccine boost at day 21 after the first dose. However, the anti SARS CoV 2 immune response was lower in patients with solid tumors who were vaccinated a second dose of BNT162b2 vaccine than in healthy individuals. These data support prioritization of patients with cancer for an early day 21 second dose of the BNT162b2 vaccine.

Social psychological patterns of managing the coronavirus diseaseDr Wango Geoffrey
Health, human development and overall wellbeing are highly intertwined and the coronavirus disease (COVID-19) makes this most implicit especially for the low and middle-income countries. More than ever, there is a need to develop a functional health system that fosters social economic political development in developing countries such as Kenya. This paper makes a case for expanded social-psychological interventions patterns for the management of COVID-19. The aim is to develop a model for health-care investment amidst COVID-19 and provide the operations and structure of strategies leading to successful management of the epidemic. This involves a comprehensive social-psychological approach in the health-care system that fosters improved health and wellbeing through a more wide-ranging understanding to enhance the involvement of the individual, family, community and nations. The framework examines the various intervention strategies in COVID-19 as well as the underlying engrossment in the strategies with an aim of successfully involving the individual in a systematic social psychological understanding of COVID-19. The model provided is relevant to health-care strategies in post-COVID-19.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

Editor's Notes
.
For today’s webinar
Infectious agent or Causative Agent: The greater the virulence (ability to grow and multiply), invasiveness (ability to enter tissue), and pathogenicity (ability to cause disease), the greater the possibility that the organism will cause infection.
The reservoir of an infectious agent is the habitat in which the agent normally can thrive and reproduce.
Portal of exit is the path by which a pathogen leaves its reservoir. The portal of exit usually corresponds to the site where the pathogen is localized. For example, influenza viruses and Mycobacterium tuberculosis exit the respiratory tract, cholera vibrios in feces. Some bloodborne agents can exit by crossing the placenta from mother to fetus (rubella, syphilis, toxoplasmosis), while others exit through cuts or needles in the skin (hepatitis B) or blood-sucking arthropods (malaria).
Modes of Transmission is the method of transfer by which the organism moves or is carried from one place to another. Can either be direct through contact or droplets, and indirect such as airborne infections, vehicle borne and vector borne infections. This will be discussed in the next lecture on standard and transmission based precautions.
The portal of entry refers to an opening allowing the microorganism to enter a susceptible host.
The final link in the chain of infection is a susceptible host. Susceptibility of a host depends on genetic or constitutional factors, specific immunity, and nonspecific factors that affect an individual's ability to resist infection or to limit pathogenicity.
