Active clinical trials for "Fever"

This study is part of a larger prospective cohort study (JOKA), designed to study febrile illness occurring during a travel to the tropics, as well as the evaluation of the clinical use of malaria rapid diagnostic tests (RDT) by travelers or their peers during travel, as a decision aid for the management of febrile illness in the tropics. Filter paper blood spots and paired serology are used in addition to routine post-travel evaluation, to study the incidence and etiological spectrum of febrile illness occurring during travel to the tropics. The study will yield valuable and prospective data of incidence rate, the clinical and etiological spectrum, clinical course and outcome of febrile illness during (and post-)travel in a prospective cohorts of travelers. This knowledge may lead to better pre-travel advice.

Yellow fever is an acute viral disease transmitted by mosquitoes in South America, Central America and Africa. It is more prevalente in males gender and the age above 15 years due to the greater exposure in the wild endemic area of yellow fever. According to the World Health Organization (WHO), a single dose of the yellow fever vaccine is sufficient to maintain protective immunity against yellow fever for a lifetime, therefore a booster dose is not required. This issue is difficult to evaluate because there is no serological correlate of protection against yellow fever and seropositivity is defined with several cut-off points. Although studies indicate that the duration of protection after vaccination is long, many studies have demonstrated a reduction of the antibody titrer over the years. Consequently, there is more concern about people who live in endemic areas. For this reason, Brazil recommends revaccinating once at least until additional studies are performed. It is important to know the duration of immunity induced by lower doses of YF vaccine. In our knowledge, there is a lack of clinical studies evaluating the immunity duration of the yellow fever vaccine with lower doses. This information is relevant to subsidize the routine recommendation of YF vaccine fractional dose for adults.

Evaluate the reproducibility and validate a posteriori a new rule of clinical decision on a multi-center population of children with a post-chemotherapy febrile neutropenia

To test whether Karius Infectious Disease Diagnostic Sequencing assay can detect Dengue Virus in plasma from suspected cases of Dengue or Dengue Fever like-illnesses from samples collected as part of a hospital-based multi-site study conducted in Nepal.

Febrile seizures (FS) are the most common neurological disorder in chilhood. The etiology of FN is still the subject of numerous studies and it is known that it can depend on genetic predisposition.

Whole blood samples will be collected from febrile patients presenting with fever of unknown origin and flu-like syndromes. Collection sites will consent patients and collect one (1) 4 mL whole blood sample from adults and either (1) 2 mL pediatric whole blood sample or 0.5 mL whole blood sample collected in a micro collection container from pediatric patients from each patient enrolled into the study. Study site will test whole blood samples received from collection sites daily using the Applied Biosystems™ Bacillus anthracis Detection Kit. Data generated will demonstrate product specificity when testing febrile whole blood samples.

The Academic centre for Malignant Hyperthermia of Masaryk University (ACMHMU) was established in 2021 in Brno, Czech Republic and consists of four academic departments of Medical Faculty of Masaryk University in two tertiary university hospitals, University Hospital Brno and St. Anne Faculty Hospital. These departments collaborated and operated since 2002 and since 2019 is Brno one of the of centre of EMHG (www.emhg.org). Aim of this study was to describe the Czech and Slovak (CZ-SK) cohort of MHS patients, the biggest Slavonic MHS cohort known by now, and to fill the knowledge gap about the Slavonic population in perspective of MH.

The study is conducted in order to evaluate the performance of the NIT thrmometer by comparing the predictive measurement to equilibrium measurement and to make a final tuning to the thermometer algorithm.

The purpose of this study is to detect acute febrile episodes and dengue infection in five Latin American countries to assess dengue seroprevalence. Primary objectives: To identify acute febrile episodes among the cohort in order to detect the presence of dengue infection. To describe the dengue seroprevalence among the cohort at baseline and at the end of the study.

The purpose of this study was to define and classify antibacterial agents used in Turkey for patients with febrile neutropenia.
