COVID-19 and Alzheimer’s Disease
2021
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a neurotropic virus with a high neuroinvasive potential. Indeed, more than one-third of patients develop neurological symptoms, including confusion, headache, and hypogeusia/ageusia. However, long-term neurological consequences have received little interest compared to respiratory, cardiovascular, and renal manifestations. Several mechanisms have been proposed to explain the potential SARS-CoV-2 neurological injury that could lead to the development of neurodegenerative diseases, including Alzheimer’s Disease (AD). A mutualistic relationship between AD and COVID-19 seems to exist. On the one hand, COVID-19 patients seem to …
Post-acute COVID-19 neurological syndrome: A new medical challenge
2021
In December 2019, in Wuhan (China), a highly pathogenic coronavirus, named SARS-CoV-2, dramatically emerged. This new virus, which causes severe pneumonia, is rapidly spreading around the world, hence it provoked the COVID-19 pandemic. This emergency launched by SARS-CoV-2 also had, and still has, devastating socio-economic aspects. Assessing the impact of COVID-19 on vulnerable groups of people is crucial for the adaptation of governments’ responses. Growing scientific evidence suggests that it is essential to keep the attention on people after acute SARS-CoV-2 infection; indeed, some clinical manifestations are frequently present even after recovery. There is consensus on the need to defi…
A novel heuristic algorithm for the modeling and risk assessment of the COVID-19 pandemic phenomenon
2020
This article belongs to the special issue: Soft computing techniques in materials science and engineering Summarization: The modeling and risk assessment of a pandemic phenomenon such as COVID-19 is an important and complicated issue in epidemiology, and such an attempt is of great interest for public health decision-making. To this end, in the present study, based on a recent heuristic algorithm proposed by the authors, the time evolution of COVID-19 is investigated for six different countries/states, namely New York, California, USA, Iran, Sweden and UK. The number of COVID-19-related deaths is used to develop the proposed heuristic model as it is believed that the predicted number of dai…
Percutaneous tracheostomy in COVID patients. Experience in our hospital center after one year of pandemic and review of the literature
2021
Background The pandemic caused by SARS-COV-2 has caused an increase in the need of tracheostomies in patients affected with respiratory distress syndrome. In this article we report our experience during a year of pandemic, we develop our surgical technique to perform percutaneous tracheostomy with the patient in apnea and we compare our results with those of other centers through a bibliographic review. Material and Methods A one-year retrospective clinical study was carried out on tracheotomies performed on patients admitted to the intensive care unit with severe SARS-CoV-2, with difficulty for ventilation or weaning. The technique performed was percutaneous, with fibroscopic control throu…
Pityriasis rosea Gibert triggered by SARS-CoV-2 infection: A case report.
2021
RATIONALE: Pityriasis rosea Gibert is an erythematous-papulosquamous dermatosis that frequently occurs in young adults. The etiopathogenesis of PR is still unknown, but is frequently associated with episodes of upper respiratory tract infections. It is likely that a new viral trigger of pityriasis rosea is the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). PATIENT CONCERNS: We present the case of a female patient in whom the diagnosis of pityriasis rosea led to the investigation and diagnosis of the SARS-CoV-2 infection. The patient presented to the Department of Dermatology for a 3âweek duration of an extremely pruritic erythematous-squamous lesion, initially on the trunk …
Coronavirus disease 2019 in chronic kidney disease
2020
Abstract The clinical spectrum of coronavirus disease 2019 (COVID-19) infection ranges from asymptomatic infection to severe pneumonia with respiratory failure and even death. More severe cases with higher mortality have been reported in older patients and in those with chronic illness such as hypertension, diabetes or cardiovascular diseases. In this regard, patients with chronic kidney disease (CKD) have a higher rate of all-type infections and cardiovascular disease than the general population. A markedly altered immune system and immunosuppressed state may predispose CKD patients to infectious complications. Likewise, they have a state of chronic systemic inflammation that may increase …
Urology practice during COVID-19 pandemic
2020
The severe acute respiratory syndrome coronavirus 2 and the disease it causes, coronavirus disease 2019 (COVID-19) is generating a rapid and tragic health emergency in Italy due to the need to provide assistance to an overwhelming number of infected patients and, at the same time, treat all the non-deferrable oncological and benign conditions. A panel of Italian urologists has agreed on possible strategies for the reorganization of urological routine practice and on a set of recommendations that should facilitate the process of rescheduling both surgical and outpatient activities during the COVID-19 pandemic and in the subsequent phases. This document could be a valid tool to be used in rou…
[Insight on how to assess and improve the response to the COVID-19 pandemic].
2022
Resumen: La pandemia de COVID-19 ha afectado de manera particularmente intensa a España, pese a su nivel de desarrollo y la elogiada solidez de su Sistema Nacional de Salud. Para comprender qué ha pasado e identificar cómo mejorar la respuesta creemos imprescindible una evaluación independiente multidisciplinaria de la esfera sanitaria, política y socioeconómica. En este trabajo proponemos objetivos, principios, metodología y dimensiones a evaluar, además de esbozar el tipo de resultados y conclusiones esperadas. Nos inspiramos en los requerimientos formulados por el panel independiente de la Organización Mundial de la Salud y en las experiencias evaluativas en otros países, y detallamos la…
Compromised Lung Volume and Hemostatic Abnormalities in COVID-19 Pneumonia: Results from an Observational Study on 510 Consecutive Patients
2021
Background: Hemostatic abnormalities have been described in COVID-19, and pulmonary microthrombosis was consistently found at autopsy with concomitant severe lung damage. Methods: This is a retrospective observational cross-sectional study including consecutive patients with COVID-19 pneumonia who underwent unenhanced chest CT upon admittance at the emergency room (ER) in one large academic hospital. QCT was used for the calculation of compromised lung volume (%CL). Clinical data were retrieved from patients’ files. Laboratory data were obtained upon presentation at the ER. Aim: The aim of this study was to evaluate the correlation between hemostatic abnormalities and lung involvement in pa…
An innovative risk-scoring system of dental procedures and safety protocols in the COVID-19 era
2020
Abstract Background The aim of this paper is to assess an innovative risk score for common dental procedures, based on the most recent contaminant SARS-CoV-2. After scoring the level of infection risk, safety procedures, advice and personal protective equipment (PPE) are recommended for the dental team in each dental practice. Methods The authors of this research analysed 42 common dental procedures on the basis of known transmission risks. In increasing order, many consider the parameters leading to different risk scores for the dental team and patients for each procedure to be: direct contact with saliva (score 1), direct contact with blood (score 2), production of low levels of spray/aer…
