Active clinical trials for "Toxemia"

Use of brain natriuretic peptide to evaluate the cardiac function in the course of meningococcal septic shock or severe sepsis.

Anesthesia for cesarean section has been a great challenge for the anesthesiologist, for mother and fetus are closely related. So the challenge is to anesthetize the mother without interfering with the physiology of the fetus. The spinal block, although safe, are not free of complications if not treated properly, may be responsible for increased fetal morbidity. Among the major side effects, there is hypotension, with potentially serious consequences for the maternal-fetal dyad. Hypotension in pregnant women at low risk may not lead to major damage, but a pregnant woman with low reserves, as is the case of pregnant women with pre-eclampsia, any drop in blood pressure of the mother can bring harm to the welfare of mother and fetus. Based on the above, the purpose of this study is to compare the effects of maternal and perinatal treatment of hypotension with ephedrine or metaraminol in pregnant women with severe preeclampsia undergoing cesarean section under spinal anesthesia. There will be a randomized, double-blind, which will be included pregnant women with severe preeclampsia with indication of cesarean section, gestational age above 34 weeks gestation and only.Will be Excluded women with hemorrhagic syndromes of pregnancy, HELLP syndrome, eclampsia, cardiovascular or cerebrovascular disease, fetal distress and absolute contraindications to spinal anesthesia. All patients are fully informed of the research objectives and will only be included in the study if they agree to participate and sign the Instrument of Consent. The project was designed following the recommendations of Resolution 196/96 of the National Health and the Declaration of Helsinki for research involving human subjects (2000). In addition, the project was submitted to the Ethics Committee in Research of the Institute of Integrative Medicine Professor Fernando Figueira, is approved. The study will be conducted from June 2011 to July 2012. The study variables are: consumption of metaraminol and ephedrine before and after birth, the occurrence of nausea and vomiting, incidence of maternal hypotension, the occurrence of reactive hypertension, occurrence of bradycardia, pH of umbilical cord, Apgar score 5 minutes, need for face mask ventilation and ICU admission.

Study of the lipid metabolism under glycemic control in septic patients who got an university 14 bed ICU. Hypothesis: establish a relationship between lipid metabolism alterations and glycemic control or infusion of exogenous insulin

Primary hyperaldosteronism confers a higher risk of cardiovascular complications compared to essential hypertension. Preliminary data is controversial in regards of excessive maternal fetal and neonatal excessive risks in pregnancy. This study aims at establishing the prevalence of PHA in an population with a recent episode of hypertensive disorder of pregnancy (HDP). The goal is to determine if a universal screening for PHA after a HDP is worthed. The investigators also wish to evaluate the complication rate in pregnant women with PHA compared to women without PHA. This is a prospective cohort study where all eligible women will be screened for PHA after a HDP episode in the last pregnancy. We will then compare PHA women to non PHA women according to pregnancy complications.

The aim of this study is to find the utility of red cell distribution width and lactate/albumin ratio as prognostic markers in sepsis and septic shock patients.

Vascular dysfunction is an important mechanism involved in organ failure, in the setting of sepsis condition, with different types of circulating endothelial cells.Transcriptom analysis via RNAseq in different types of circulating endothelial cells, comapring critically ill patients with or without sepsis will allow determining differential gene expression for signal pathways in endothelial alteration and restoration associated with sepsis.

The aim of the study was to identify co-variates associated with 30-day mortality in septic patients admitted to the emergency department in order to improve morbidity & mortality as a sequence of sepsis in Assiut & Suez Canal Universities by comparing both scores by utilizing parameters that are readily available .

Biomarkers that provide an early indicator of kidney stress could be useful in clinical practice to detect silent episodes of acute kidney injury (AKI) or for early identification of subjects at risk of AKI. Two urinary biomarkers have been identified as early indicators of AKI. The NephroCheck® test is a commercially available test that uses these biomarkers, and this study assesses the use of these in reducing negative clinical outcomes for patients with sepsis-associated AKI. The study will enroll subjects diagnosed with sepsis, including septic shock, who will be randomly assigned to either receive NephroCheck®-guided kidney-sparing and fast-tracking interventions; or to receive current Standard of Care assessment and treatment. NOTE: Participants are no longer being recruited to this study.

The goal of this observational study is to learn about the utility of biopatches predicting 30-day readmissions in patients discharged from the hospital with sepsis. The main question[s] it aims to answer are: • Does the application of a biopatch provide data that can improve prediction of an unplanned 30-day readmission following a hospitalization for sepsis. Participants will be asked to wear a biopatch on their chest for 30-days following hospital discharge or until readmission to the hospital.

Sepsis is a dysregulated host response to infection resulting in organ dysfunction. Over the past three decades, more than 30 pharmacological therapies have been tested in >100 clinical trials and have failed to show consistent benefit in the overall population of patients with sepsis. The one-size-fits-all approach has not worked. This has resulted in a shift in research towards identifying sepsis subphenotypes through unsupervised learning. The ultimate objective is to identify sepsis subphenotypes with different responses to therapies, which could provide a path towards the precision medicine approach to sepsis. The investigators have previously discovered sepsis subphenotypes in retrospective data using trajectories of vital signs in the first 8 hours of hospitalization. The team aims to prospectively classify adult hospitalized patients into these subphenotypes in a prospective, observational study. This will be done through the implementation of an electronic health record integrated application that will use vital signs from hospitalized patients to classify the patients into one of four subphenotypes. This study will continue until 1,200 patients with infection are classified into the sepsis subphenotypes. The classification of the patients is only performed to validate the association of the subphenotypes with clinical outcomes as was shown in retrospective studies. Physicians and providers treating the patients will not see the classification, and the algorithm classifying the patients will in no way affect the care of the patients. Further, all the data needed for the algorithm (vital signs from the first 8 hours) are standard of care, and enrollment in the prospective study does not require any additional data.
