Electrophysiological and olfactometric evaluation of long-term COVID-19.

COVID-19 is a public health emergency with cases increasing globally. Its clinical manifestations range from asymptomatic and acute respiratory disease to multiple organ dysfunction syndromes and effects of COVID-19 in the long term. Interestingly, regardless of variant, all COVID-19 share impairment of the sense of smell and taste. We would like to report, as far as we know, the first comprehensive neurophysiological evaluation of the long-term effects of SARS-CoV-2 on the olfactory system with potential-related neurological damage. The case report concerns a military doctor, with a monitored health history, infected in April 2020 by the first wave of the epidemic expansion while on military duty in Codogno (Milan). In this subject, we find the electrophysiological signal in the periphery, while its correlate is absent in the olfactory bulb region than in whole brain recordings. In agreement with this result is the lack of metabolic signs of brain activation under olfactory stimulation. Consequently, quantitative and qualitative diagnoses of anosmia were made by means of olfactometric tests. We strongly suggest a comprehensive series of olfactometric tests from the first sign of COVID-19 and subsequent patient assessments. In conclusion, electrophysiological and metabolic tests of olfactory function have made it possible to study the long-term effects and the establishment of neurological consequences.

[Recommendations on neurophysiological studies during the COVID-19 pandemic]. / Recomendaciones sobre estudios neurofisiológicos en tiempos de pandemia de COVID-19.

At the end of January, the current outbreak of COVID-19 coronavirus disease was declared an important international public health emergency. In Spain, since the government declared the state of alarm on 14 March 2020, doctors responsible for carrying out neurophysiological tests have been performing them without any consensus criterion or clear safety guidelines for doctors, technicians or patients. The following recommendations, based on current knowledge of the disease and therefore liable to change in the future, are proposed when the pandemic appears to have entered a process of decreasing virulence and, with it, the strict containment measures established to date. However, in view of the possibility of a second wave of the pandemic, it seems necessary to establish basic and minimum recommendations to respect the patient's right to appropriate care, similar to that provided prior to the pandemic, and to maintain minimum safety standards for the patients themselves and for the doctors, technicians and health personnel carrying out these tests. These recommendations concern the constitution of a priority based on the reason for consultation, the establishment of calls to check the patient's clinical situation before going to the outpatient department and the rules for carrying out neurophysiological tests, which are generally based on the preservation of hospital circuits, respect for and observation of the known barriers to contagion of this disease, and the use of disposable material. These recommendations are of particular interest, especially given the uncertainty of not knowing the evolution of the SARS-CoV-2 infection in the coming weeks or months.

TITLE: Recomendaciones sobre estudios neurofisiológicos en tiempos de pandemia de COVID-19.A finales de enero, la Organización Mundial de la Salud declaró el brote actual de la enfermedad por coronavirus COVID-19 como emergencia de salud pública de importancia internacional. En España, desde que el 14 de marzo de 2020 el Gobierno decretase el estado de alarma, los médicos encargados de las pruebas neurofisiológicas las hemos estado realizando sin tener un criterio consensuado ni unas pautas adecuadas de seguridad claras para los facultativos, los técnicos ni los pacientes. Las siguientes recomendaciones, basadas en el actual conocimiento de la enfermedad y, por tanto, susceptibles de variaciones en el futuro, se proponen cuando la pandemia parece que ha entrado en un proceso de disminución de la virulencia y, con ello, las medidas estrictas de confinamiento hasta ahora mantenidas; sin embargo, ante la posibilidad de una segunda oleada de rebrotes de la pandemia, parece necesario establecer unas recomendaciones básicas y de mínimos para respetar el derecho del paciente a una atención adecuada, similar a la previa a la pandemia, y mantener unos mínimos de seguridad para los propios pacientes y los médicos, técnicos y personal sanitario que realizan estas pruebas. Se trata de recomendaciones sobre el establecimiento de una prioridad basándose en el motivo de consulta, el establecimiento de llamadas de comprobación de la situación clínica del paciente antes de acudir a la consulta externa y las normas de ejecución de las pruebas neurofisiológicas, que se basan, en general, en la preservación de circuitos hospitalarios, el respeto y el cuidado de las barreras de contagio conocidas de esta enfermedad, y la utilización de material desechable. Estas recomendaciones son de especial interés, sobre todo por la incertidumbre de no saber la evolución de la infección por el SARS-CoV-2 en las próximas semanas o meses.

Impact of COVID-19 pandemic on the clinical activities related to arrhythmias and electrophysiology in Italy: results of a survey promoted by AIAC (Italian Association of Arrhythmology and Cardiac Pacing).

COVID-19 outbreak had a major impact on the organization of care in Italy, and a survey to evaluate provision of for arrhythmia during COVID-19 outbreak (March-April 2020) was launched. A total of 104 physicians from 84 Italian arrhythmia centres took part in the survey. The vast majority of participating centres (95.2%) reported a significant reduction in the number of elective pacemaker implantations during the outbreak period compared to the corresponding two months of year 2019 (50.0% of centres reported a reduction of > 50%). Similarly, 92.9% of participating centres reported a significant reduction in the number of implantable cardioverter-defibrillator (ICD) implantations for primary prevention, and 72.6% a significant reduction of ICD implantations for secondary prevention (> 50% in 65.5 and 44.0% of the centres, respectively). The majority of participating centres (77.4%) reported a significant reduction in the number of elective ablations (> 50% in 65.5% of the centres). Also the interventional procedures performed in an emergency setting, as well as acute management of atrial fibrillation had a marked reduction, thus leading to the conclusion that the impact of COVID-19 was disrupting the entire organization of health care, with a massive impact on the activities and procedures related to arrhythmia management in Italy.

Performance of electrophysiology procedures at an academic medical center amidst the 2020 coronavirus (COVID-19) pandemic.

A global coronavirus (COVID-19) pandemic occurred at the start of 2020 and is already responsible for more than 74 000 deaths worldwide, just over 100 years after the influenza pandemic of 1918. At the center of the crisis is the highly infectious and deadly SARS-CoV-2, which has altered everything from individual daily lives to the global economy and our collective consciousness. Aside from the pulmonary manifestations of disease, there are likely to be several electrophysiologic (EP) sequelae of COVID-19 infection and its treatment, due to consequences of myocarditis and the use of QT-prolonging drugs. Most crucially, the surge in COVID-19 positive patients that have already overwhelmed the New York City hospital system requires conservation of hospital resources including personal protective equipment (PPE), reassignment of personnel, and reorganization of institutions, including the EP laboratory. In this proposal, we detail the specific protocol changes that our EP department has adopted during the COVID-19 pandemic, including performance of only urgent/emergent procedures, after hours/7-day per week laboratory operation, single attending-only cases to preserve PPE, appropriate use of PPE, telemedicine and video chat follow-up appointments, and daily conferences to collectively manage the clinical and ethical dilemmas to come. We discuss also discuss how we perform EP procedures on presumed COVID positive and COVID tested positive patients to highlight issues that others in the EP community may soon face in their own institution as the virus continues to spread nationally and internationally.
