Difference in mortality rates in hospitalized COVID-19 patients identified by cytokine profile clustering using a machine learning approach: An outcome prediction alternative.

COVID-19 is a disease caused by the novel Coronavirus SARS-CoV-2 causing an acute respiratory disease that can eventually lead to severe acute respiratory syndrome (SARS). An exacerbated inflammatory response is characteristic of SARS-CoV-2 infection, which leads to a cytokine release syndrome also known as cytokine storm associated with the severity of the disease. Considering the importance of this event in the immunopathology of COVID-19, this study analyses cytokine levels of hospitalized patients to identify cytokine profiles associated with severity and mortality.

Zika virus: Report from the task force on tropical diseases by the world Federation of Societies of intensive and critical care medicine.

Zika fever is an acute infectious disease caused by the Zika virus (ZIKV), an RNA virus belonging to the genus Flavivirus. ZIKV can be transmitted by bites from Aedes aegypti and Aedes albopictus species, sexual activity, blood transfusion and from mother to fetus during pregnancy and delivery. A total of 50 territories and countries in the Americas had reported ZIKV infections.

Chikungunya: Report from the task force on tropical diseases by the World Federation of Societies of intensive and critical care medicine.

Chikungunya is an arbovirus that is transmitted by the Aedes mosquito causing a febrile illness with periodic outbreaks in large parts of the world. In the last decade it has become a public health concern in a host of countries and has affected international tourists. In the vast majority of cases Chikungunya presents as an acute febrile illness, associated with rash, headache, myalgia and debilitating arthralgia or even polyarthritis.

Dengue fever: Report from the task force on tropical diseases by the World Federation of Societies of Intensive and Critical Care Medicine.

Dengue is an arbovirus affecting humans and spread by mosquitoes. Severe dengue follows a secondary infection with a different virus serotype. The problem is truly global as it is endemic in over 100 countries.

Leptospirosis: Report from the task force on tropical diseases by the World Federation of Societies of Intensive and Critical Care Medicine.

Leptospirosis is a zoonosis caused by a gram negative aerobic spirochete of the genus Leptospira. It is acquired by contact with urine or reproductive fluids from infected animals, or by inoculation from contaminated water or soil. The disease has a global distribution, mainly in tropical and subtropical regions that have a humid, rainy climate and is also common in travelers returning from these regions.

Viral hemorrhagic fever in the tropics: Report from the task force on tropical diseases by the World Federation of Societies of Intensive and Critical Care Medicine.

Viral hemorrhagic fevers (VHFs) are a group of illnesses caused by four families of viruses namely Arenaviruses, Filoviruses, Bunyaviruses, and Flaviviruses. Humans are not the natural reservoir for any of these organisms and acquire the disease through vectors from animal reservoirs. In some conditions human to human transmission is possible increasing the risk to healthy individuals in the vicinity, more so to Health Care Workers (HCW).

Geo-economic variations in epidemiology, patterns of care, and outcomes in patients with acute respiratory distress syndrome: insights from the LUNG SAFE prospective cohort study.

Background: Little information is available about the geo-economic variations in demographics, management, and outcomes of patients with acute respiratory distress syndrome (ARDS). We aimed to characterise the effect of these geo-economic variations in patients enrolled in the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG SAFE).

Methods: LUNG SAFE was done during 4 consecutive weeks in winter, 2014, in a convenience sample of 459 intensive-care units in 50 countries across six continents.
