Active clinical trials for "Fever"

Women who receive epidural analgesia during labor are more likely to develop fever than those who do not. Maternal fever during labor can produce various harmful effects on both mothers and infants. The investigators speculate that the effect of epidural analgesia is associated with the development of maternal fever, i.e., better analgesia is associated with higher risk of maternal fever.

Background: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) is an emerging surgical procedure for peritoneal carcinomatosis. Despite the survival benefits from HIPEC, complications have been reported with major morbidity and mortality. Acute kidney injury (AKI) is one of the major complications. To date, there is no adequate biomarker to predict the risk of AKI after HIPEC and monitor the renal prognosis after HIPEC-related AKI. Aims: Establish a HIPEC cohort database, including retrospective data and prospective database Identify the incidence of AKI after HIPEC and the severity Identify the biomarker to predictive HIPEC-related AKI and monitor renal prognosis. Understand the risk factors for AKI post- HIPEC helps improve pre-operative patient selection and optimization, facilitate tailoring of chemotherapy, and foster closer peri-operative monitoring and fluid management in at-risk patients. Methods: Patients with the peritoneal carcinomatosis, planning to receive HIPEC and agree to participate the study will be recruited. Retrospective analyze the renal prognosis of patients with HIPEC procedure and identify the clinical and biochemistry risk factors of HIPEC-related AKI Prospective collect the information of patients who are enrolled into this study. The information includes clinical information, biochemistry, electrolyte, and novel biomarkers of body fluids (blood, and urine). The samples of body fluids will be collected on pre-operative day, post-operative 2h, 24h, 48h, 72h and day 7. Patients with or without post-HIPEC AKI will be analyzed. Hypothesis: Peri-operative dehydration and cisplatin-based regimen are the major risk factors to cause AKI. The novel biomarker, high peri-operative urine NGAL and serum cystatin C, β2 Microglobulin are the predictive markers of HIPEC- related AKI.

Ibuprofen, the active ingredient in Nurofen and Advil, is a commonly used drug in children. There is very limited data about Ibuprofen concentrations in the cerebro spinal fluid (CSF). The objective of the current study is to describe concentrations of ibuprofen in the CSF of infants and children after administration of ibuprofen. We will study infants presenting to the Emergency Department (ED) with fever who received ibuprofen. A complete sepsis workup including sampling of blood and CSF is conducted in cases of suspected meningitis. We will measure ibuprofen in the blood and CSF obtained during the sepsis workup. A better understanding of the pharmacokinetics of ibuprofen and its penetration into the CSF will unable us to suggest more accurate dosing guidelines, and to better predict the effects of this commonly used drug.

To inform the feasibility of conducting a study to test different temperature thresholds at which clinicians deliver interventions to reduce fever (i.e. antipyretic interventions) in critically ill children with fever due to infection.

This clinical study is a multiple center, registering and real-world conditional research. The breast cancer patients planning for chemotherapy evaluated with medium-high risk of febrile neutropenia (FN) are recruited, receiving the first level prophylactic use of PEG-rhG-CSF or the second level prophylactic use of PEG-rhG-CSF in at least two cycles of chemotherapy according to real-world clinical judgement and choice by physicians in local cancer center. Comparing real conditional-FN rate, FN-caused hospitalization rate and antibiotic use rate, direct/indirect medical cost.

A mobile suitcase laboratory for EBOV point-of-care (POC) detection at Ebola treatment centers was successfully implemented in Guinea during the large Ebola virus disease (EVD) outbreak in West-Africa 2014-2015. It was shown that isothermal amplification (Recombinase Polymerase Amplification (RPA)) could be efficiently used to test suspect EVD cases and local teams were trained in and successfully deployed with this fast method. In the frame of this project we want to train teams in DRC and expand RPA testing capacity to the differentials recommended by the WHO. Existing RPA assays for all parameters will be included into a multistrip for simultaneous use. This will be integrated with a simple biosafe extraction method. Implementing this approach and testing in the ongoing EVD outbreak will provide teams in DRC with response capacity for future EVD outbreaks.

Zinc and vitamin d deficiency are associated with a state of inflammation/atherosclerosis. There are studies demonstrating an association between vitamin d deficiency and respiratory illnesses. Both zinc and vitamin d are associated with oxidative stress and inflammation.

Yellow fever is an acute febrile infectious disease transmitted to man urban cycle by mosquitoes infected by an arbovirus of the genus Flavivirus family Flaviviridae. Its occurrence is recorded in South America Central America and Africa. In cities the yellow fever vector is the Aedes aegypti mosquito which also transmits dengue viruses zika and chikungunya. This disease is more frequent in males and the most affected age group is above fifteen years due to the greater exposure related to the penetration in wild areas of the endemic zone of yellow fever. Another risk group is unvaccinated people who live near wild environments where the virus circulates. According to the World Health Organization 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 question 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 there is considerable evidence in the literature that antibody titer falls over the years reaching levels considered as seronegative in at least a portion of the vaccinees. This is of more concern to people living in endemic areas who are exposed to the virus throughout their lives. For this reason Brazil recommended revaccinating once at least until additional studies were done. The need to increase Bio Manguinhos production capacity to meet the increased demand from Brazil and other countries is urgent. The occurrence of epidemics when millions of individuals need to be vaccinated in a short period of time exceeds production capacity and this is a recurrent problem. The current vaccine has a very high potency well above the thousand international units recommended by World Health Organization. But we need to generate additional evidence that very low doses of viral particles in the yellow fever vaccine are still immunogenic and that their immunogenicity can be maintained for at least ten years after vaccination. This evidence will support the rapid increase of their availability by the fractionation of doses or other alternatives.

Rationale: Malignant hyperthermia and rhabdomyolysis are phenotypes that have long been considered to occur only in response to external stimuli (trigger anaesthesia and physical exhaustion) show several features of a continuous disease manifestation. Previous studies showed prolonged bleeding time after injury, selective immunological advantages, axial muscle weakness and several social difficulties. A detailed study of the neuromuscular and multisystem features of patients with RYR1-related malignant hyperthermia or rhabdomyolysis is needed to provide clarification about the continuous and multisystem disease manifestations in these patients. Objective: Primary Objective: There are three primary objectives in this study. To investigate the neuromuscular involvement of RYR1 related MH and rhabdomyolysis. To investigate the immunological changes in subjects with RYR1 related MH and rhabdomyolysis. To identify multisystem features of RYR1 related MH and rhabdomyolysis. There are no secondary objectives. Study design: The design of the study will be a clinical, open, observational study. The study consists of three parts; a clinical, imaging and immunological part. Study population: Patients with a history of malignant hyperthermia susceptibility (MHS), and/or a history of rhabdomyolysis related to a variant in RYR1. Intervention (if applicable): Not applicable. Main study parameters/endpoints: The study consists of three parts. Each part has it's own main study parameters Clinical part: the results of the questionnaire study compared to standardizes normal values and the results of the comprehensive clinical assessment. Imaging part: fatty infiltration and hypertrophy of proximal and axial muscles. Immunological part: circulating and leukocyte released anti- and pro-inflammatory cytokine levels compared to healthy age and sex matched controls.
