Assessment of the frequency of coughing and sneezing triggered by nasopharyngeal swabbing in the pandemic setting

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

A variety of medical procedures are classified as aerosol generating. However there is no consensus on whether some procedures such as nasopharyngeal swabbing can generate aerosols. During specimen collection, the contact of the nasopharyngeal swab with the respiratory mucosa often triggers defense reflexes such as sneezing and coughing, which generate airborne particles. The accumulation and persistence of a viral load from infectious aerosols for hours after their generation can represent a...

Speaking COVID-19: supporting COVID-19 communication and engagement efforts with people from culturally and linguistically diverse communities

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

CONCLUSION: Alliances must be set up that can be activated in the future to reduce issues around resource development, translation, and dissemination of messages to minimise gaps in the response. Financial assistance must be provided in a timely way to community organisations to support the development and dissemination of culturally appropriate communication materials.

Evolution and Evaluation of a Structured Applied Physics Course for Radiation Oncology and Radiation Physics Trainees

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

We sought to supplement medical physics textbook knowledge and clinical learning with case-based discussions. To our knowledge, this is the first report on a structured combined applied physics curriculum for radiation oncology (RO) and medical physics (MP) trainees. We reviewed our yearly applied physics course given from the years 2016-2021 inclusive. The number of applied physics trainees ranged from 7 to 14 per year (2-9 RO and 3-6 MP residents per year). Each session was taught by a pair of...

Effectiveness of delayed second dose of AZD1222 vaccine in patients with autoimmune rheumatic disease

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

There is paucity of data on extended dosing interval between two doses of AZD1222 (AstraZeneca) in patients with Autoimmune Rheumatic Diseases (AIRD). We aimed to study the humoral response and rate of breakthrough infections between the two groups who had received the second dose of vaccine at 4 weeks (Group 1) and 10-14 weeks (Group 2). From established cohort [COVID-19 vaccination cohort from CARE(CVCC)] of vaccinated patients with AIRD, those who had received AZD1222 were included and...

The humoral response and antibodies against SARS-CoV-2 infection

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

Two and a half years into the COVID-19 pandemic, we have gained many insights into the human antibody response to the causative SARS-CoV-2 virus. In this Review, we summarize key observations of humoral immune responses in people with COVID-19, discuss key features of infection- and vaccine-induced neutralizing antibodies, and consider vaccine designs for inducing antibodies that are broadly protective against different variants of the SARS-CoV-2 virus.

The 2022 outbreak and the pathobiology of the monkeypox virus

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

Following two reports of monkeypox virus infection in individuals who returned from Nigeria to the USA, one who returned to Texas (July 2021) and the other to the Washington, DC area (November 2021), the number of monkeypox infection have dramatically increased. This sounded an alarm of potential for spreading of the virus throughout the USA. During 2022, there was a report of monkeypox virus infection (May 6, 2022) in a British national following a visit to Nigeria who developed readily...

Revitalization of tourism and hospitality sector: preempting pandemics through lessons learned

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

The devastating effects of the COVID-19 pandemic have left many repercussions for the tourism industry to preempt any future catastrophe of this nature. The research aims to propose recommendations for the post-COVID-19 business world to revitalize and reclaim their market space and win back their volumes without any fear of indefinite closures and continued lockdowns in the industry. Drawing from the literature, the study assumed revitalization through responsiveness, use of advanced...

Equipment-free, unsupervised high intensity interval training elicits significant improvements in the physiological resilience of older adults

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

CONCLUSIONS: This is the first study to show that short-term, time-efficient, equipment-free, HIIT is able to elicit improvements in the CRF of older adults irrespective of supervision status. Unsupervised HIIT may offer a novel approach to improve the physiological resilience of older adults, combating age-associated physiological decline, the rise of inactivity and the additional challenges currently posed by the COVID-19 pandemic.

Hearing loss and the COVID-19 pandemic

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

OBJECTIVE: Hearing loss is an important public health problem. Its causes vary, including infections, noise, and aging. The first wave of the COVID-19 pandemic occurred in April 2020 in Japan. During the pandemic, people were urged to stay at home and drastically changed their lifestyles. This study aimed to examine hearing loss before and during the pandemic. The prevalence during the pandemic after April 2020 was compared for the period in 2019. Study subjects were those who received health...

Total Chemical Synthesis of a SARS-CoV-2 Miniprotein Inhibitor LCB1

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

Native chemical ligation is a widely used technique for peptide fragment condensation in aqueous solutions, which has broken through the length limitation of traditional solid-phase peptide synthesis. It can achieve high-efficient chemical synthesis of proteins containing more than 300 amino acid residues. Peptide hydrazide, as a valuable reagent equivalent to a thioester peptide, can be easily and efficiently prepared by the Fmoc-based SPPS method and has been widely used in native chemical...

Fundamentals of Biosensors and Detection Methods

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

Biosensors have a great impact on our society to enhance the life quality, playing an important role in the development of Point-of-Care (POC) technologies for rapid diagnostics, and monitoring of disease progression. COVID-19 rapid antigen tests, home pregnancy tests, and glucose monitoring sensors represent three examples of successful biosensor POC devices. Biosensors have extensively been used in applications related to the control of diseases, food quality and safety, and environment...

A comparative analysis of experienced uncertainties in relation to risk communication during COVID19: a four-country study

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

CONCLUSION: We suggest that in future outbreaks, communicators and policy makers could improve the way in which affected communities assess their risk, and increase the trust of these communities in response efforts by addressing non-epidemiological uncertainties in RCCE strategies.

An Argentinean cohort of patients with rheumatic and immune-mediated diseases vaccinated for SARS-CoV-2: the SAR-CoVAC Registry-protocol and preliminary data

Di |2022-06-27T15:00:00+02:00Giugno 27th, 2022|Categorie: Coronavirus PubMed|

CONCLUSIONS: In this national cohort of patients, the most common vaccines used were Gam-COVID-Vac and ChAdOx1 nCoV-19. A quarter of the patients presented an AE and 5.1% presented SARS-CoV-2 infection after vaccination, in most cases mild.
