Influence of land cover in the atmospheric water vapor content and the generation of summer storms in the Turia River Basin

2022

Les tronades d'estiu representen una font d’aigua important en la conca mediterrània, ja que aporten aigua durant els mesos més secs de l’any, amb la qual cosa ajuden a mantenir els cabdals dels principals rius. Aquests sistemes convectius estan associats a les circulacions de brisa que dominen durant l'estiu. La brisa es canalitza a través de les valls assolint les capçaleres dels principals rius on es generen línies de convergència, és a dir, zones on les masses d’aire superficials s’injecten a capes més altes de l’atmosfera i donen lloc a aquest tipus de fenòmens meteorològics. A part de la topografia, altres factors que poden influenciar la formació de tronades d'estiu són els fluxos su…

Coagulation disorders in SARS-CoV-2 infection

2020

A better understanding of the pathogenetic mechanisms triggered by SARS-CoV-2 infection may contribute to a more effective management of patients with COVID-19. Coagulation dysfunction is a key pathogenetic element of this disease as well as a challenge for practitioners. Marked inflammatory process found in severe forms of COVID-19, the complement activation, the cytokine storm, and disruption of the renin-angiotensin-aldosterone system are involved in the onset of thrombotic microangiopathy and large vessel coagulopathy. Virus-induced procoagulant activity occurs at the systemic level. Intravascular microthrombi disrupt vascularization in various tissues and organs, contributing to the oc…

Exploring Sodium Glucose Co-Transporter-2 (SGLT2) Inhibitors for Organ Protection in COVID-19

2020

Hospital admissions and mortality from the Coronavirus disease 2019 (COVID-19) pandemic are spreading throughout the world, and second and third waves are thought to be likely. Risk factors for severe COVID-19 include diabetes, chronic kidney disease and cardiovascular disease. Currently, there is no vaccine and no approved therapy. Therapeutic approaches are aimed at preventing viral replication and spread, limiting the impact of the inflammatory overdrive (cytokine storm), preventing thromboembolic complications and replacing or supporting organ function. However, despite organ support, mortality is currently 65% for those receiving advanced respiratory support and 78% for those requiring…

The value of total thyroidectomy as the definitive treatment for Graves’ disease: A single centre experience of 594 cases

2019

Highlights • Total thyroidectomy is a safe and effective treatment for Graves’ disease. • It is associated with a very low incidence rate of post-operative complications. • Total thyroidectomy offers a rapid and definitive control of hyperthyroidism and its related symptoms.

The biological anakinra appears promising to halt cytokine storm syndrome seen in severe courses of COVID-19. However, immunosuppression with anakinra may facilitate sepsis, necessitating continuous screening for bacterial superinfections.

An Overview of Asthma and COVID-19: Protective Factors Against SARS-COV-2 in Pediatric Patients.

2021

Coronavirus disease 2019 (COVID-19) is a pandemic infectious disease caused by severe acute respiratory syndrome coronavirus SARS-COV-2. Aberrant innate immunity response and cytokine storm are responsible for the syndrome. Apparently, in asthmatic patients, the inadequate antiviral immune response and the tendency for asthma exacerbation evoked by common respiratory viruses could explain increased susceptibility to SARS-COV-2 infection. However, asthma has not been suggested to be a risk factor in COVID-19 patients. Therefore, in asthmatic patients some potential protective mechanisms against SARS-COV-2 have been hypothesized, like type 2 immune response, number of eosinophils, overproduct…

USING HIGH RESOLUTION RAINGAUGE DATA FOR STORM TRACKING ANALYSIS IN THE URBAN AREA OF PALERMO, ITALY

2009

This paper presents a comparative analysis between rain-gauge storm tracking techniques in order to achieve a better knowledge of the rainfall dynamics over an urbanized area. The temporal and spatial distribution and kinematics of short term rainfall are recognized as one of the most important reasons in error production in rainfall-runoff on urban catchments. The uncertainty due to rainfall variability can greatly affect urban drainage modeling performance and reliability thus reducing the confidence of operators in their results. Modeling representations of urban catchments and drainage systems are commonly adopted for surface flooding forecasting and management and an adequate knowledge…

Effects of low laser level therapy in rehabilitation of patients with COVID19 pneumonia

2021

Introduction. An unprecedented public health crisis has been triggered worldwide by SARS-CoV-2’s high contagiosity and it’s mortality rates of 1-5%. Although the majority of COVID-19 cases have a good outcome, there is a small percentage that develop severe pneumonia and citokine storm and may be in the need of mechanical ventilation. Methods. Identifying the exact drivers of the excessive inflammation and the biomarkers that can predict a hyperinflammatory response to SARS-CoV-2 would be extremly helpful in finding efficient anti-inflammatory interventions that may stop the progression to acute respiratory distress syndrome (ARDS). Results. In the search for such interventions we have iden…

IgA-Dominant Infection-Associated Glomerulonephritis Following SARS-CoV-2 Infection

2021

The renal involvement of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been reported. The etiology of kidney injury appears to be tubular, mainly due to the expression of angiotensin-converting enzyme 2, the key joint receptor for SARS-CoV-2; however, cases with glomerular implication have also been documented. The multifactorial origin of this renal involvement could include virus-mediated injury, cytokine storm, angiotensin II pathway activation, complement dysregulation, hyper-coagulation, and microangiopathy. We present the renal histological findings from a patient who developed acute kidney injury and de novo nephrotic syndrome, highly suggestive of acute IgA-domina…
