Filter by:The Autonomic Nervous System (ANS) regulates the inflammatory response in real time, just as it controls heart rate and other vital functions. Many studies have investigated induced stimulation of the vagus nerve and its therapeutic effect in inhibiting TNFα (Tumor Necrosis Factor alpha) secretion, and therefore the risk of hypotension, septic shock, organ dysfunction during inflammation. While the anti-inflammatory effect of the autonomic nervous system on inflammation has been well studied, conversely, the effect of major inflammation on the balance of the autonomic nervous system is more difficult to understand. The inflammatory reflex could be overwhelmed and the regulatory centers of the brainstem dysregulated during situations of extreme inflammation.
This study was a single-center, open clinical study in Chinese septic patients with or without acute kidney injury. The aims of this study were to obtain the blood concentration and pharmacokinetic parameters of meropenem and piperacillin, exosome information and endogenous biomarker, and to explore the functional changes of OATs under the condition of sepsis and acute kidney injury.
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.
Profound and concomitant cardiovascular hemodynamic changes, necessary to support fetoplacental development and its increasing supply demands, occur during a physiological pregnancy characterized by an increase in cardiac output, heart rate and plasma volume, and fall in vascular resistance and blood pressure. The result of these changes is a volume overload that will lead to a compensatory transient left ventricular eccentric hypertrophy. This, together with the pro-inflammatory state typical of pregnancy, represents the pregnancy as a stress-test for the maternal cardiovascular system. Pregnancies complicated by hypertensive disorders of pregnancy (HDP), particularly those with early onset and/or complicated by intrauterine fetal growth restriction (FGR), are characterized by a cardiovascular maladaptation. Women who experienced HDP in pregnancy, especially pre-eclampsia (PE), more often develop later in life ischemic heart disease, hypertension and stroke, obesity, dyslipidemia, and end-stage renal disease. Regardless its clinical impact, very little knowledge is available on the mechanisms by which PE could lead to cardiovascular disease (CVD), and, especially, to heart failure after pregnancy. Preliminary results suggest a cross-talk between pregnancy-induced biomarkers and cardio-vascular system. Particularly, cultures of neonatal rat cardiomyocytes and fibroblasts were used to investigate the role of the serum of women with HDP in regulating their proliferation. 5-ethynyl-2'-deoxyuridine (EdU) was administered to label DNA synthesis in proliferating cells. After 3 days of in vitro culture, EdU incorporation was analyzed upon immunofluorescence staining using specific antibodies by high content microscopy. A possible protective effect exerted by the selected sera against apoptosis was evaluated, as well, by Caspase activation. Moreover, the effect of cardiomyocytes and fibroblasts proliferation and apoptosis on maternal hemodynamic parameters was evaluated using median regression models. These data show that the serum of women with HDP triggers a net increase in the percentage of proliferating cardiomyocytes compared to controls. Moreover, there were relationship between cardiomyocytes and fibroblasts proliferation and maternal hemodynamics parameters thus, supporting the hypothesis that the serum of women with HDP may contain factors capable of stimulating cardiac cells in response to the cardiovascular stress-test
To correlate fetal Pulmonary artery Doppler parameters with neonatal outcome in patients diagnosed with hypertensive disorders of pregnancy.
Sepsis is a life-threatening condition, caused by a systemic infection. It is particularly dangerous in already fragile populations and needs to be identified quickly to be treated as fast as possible, as discussed during the 2016 sepsis consensus and highlighted by the 2021 Surviving Sepsis Campaign. Yet, while there are scores to quickly identify patients who are at an increased risk of mortality (namely quick-SOFA, q-SOFA), these scores are also highly unspecific and cannot guarantee an adequate risk stratification. Therefore, it would be extremely valuable to further stratify mortality risk in patients who present to the emergency medical evaluation, especially those who present with stable hemodynamics but are at increased risk of decompensation during hospital stay. Furthermore, in the emergency room, it is sometimes impossible to re-evaluate patients regularly, thus, it would be important to immediately identify high-risk patients. Unfortunately, at the moment, there is no consensus. Through this study, the investigators will try to identify ultrasound parameters and biochemical markers which can be obtained during the first visit in the emergency room (ER) and that allow a quick risk stratification of patients with sepsis. The rationale of this study is to improve early identification of septic patients who are at risk of rapid deterioration in the course of their permanence in the ER and the hospital wards in general. The investigators selected a number of clinical, laboratory and bedside ultrasound parameters which have been previously shown to be correlated with mortality in sepsis, and will seek to identify which among these parameters best correlates with prognosis when acquired in the very first minutes of a patient's arrival in the ER. The objective would be to analyse these parameters and eventually to propose a new early sepsis score which might help the emergency physician to better tailor its efforts and clinical resources to the most sick patients.
The goal of this interventional clinical research study is to assess the efficacy of a 12-week precision exercise training intervention to improve exercise tolerance in sepsis survivors. The main question it aims to answer is does a 12-week precision exercise training program improve constant load exercise time in sepsis survivors? Participants will: - Answer questionnaires related to patient reported outcomes and give a blood sample - Perform a constant load exercise test - Complete 12-weeks (3 x per week, 36 session in total) of precision exercise training consisting of individualized, nonlinear periodized strength and aerobic exercise training. Researchers will compare the exercise group to an attention control group of sepsis survivors who do not receive exercise training but instead undergo usual care procedures and receive general lifestyle advice 1x per week.
Septic shock is defined as sepsis with persistent hypotension requiring vasopressors to maintain mean arterial pressure (MAP)≥ 65 mmHg and a serum lactate level of > 2 mmol/L (18 mg/dL) despite sufficient volume resuscitation . Hypovolemia (both relative and absolute) and reduced vascular tone have a role in determining the severity of hypotension in septic shock
Rationale: Early diagnosis of sepsis in neonates is complicated as the signs and symptoms are nonspecific. Although blood culture is the gold standard for the diagnosis, false-negative results and long incubation period of 36-72 hours limits the use of blood culture to rule out sepsis at initial suspicion. Since delay in diagnosis may lead to progressive deterioration, antibiotics are often started empirically at initial sepsis suspicion, awaiting results of the blood culture. Consequently, uninfected infants are often unnecessarily exposed to empirical antibiotics. To reduce unnecessary treatment of non-infected infants, an early, sensitive and specific diagnostic tool would be helpful to guide clinicians faster when to discontinue antibiotics. Molecular Culture (MC) via IS-pro is a novel, advanced, molecular culture technique which is able to culture bacteria within 4 hours after blood sampling. MC might thus be a potential diagnostic tool to detect or rule out sepsis in infants quickly, however data on MC for diagnosis of sepsis in this population is limited. Objective: The aim of this study is to evaluate whether MC is of additive predictive value for the diagnosis sepsis in this vulnerable group. Study design: Prospective observational cohort study. Study population: All infants suspected for neonatal sepsis of both early and late onset will be eligible for study participation. They will be treated according to the standard local guidelines. Intervention (if applicable): In case of a suspicion of sepsis at birth, blood will be collected for a conventional blood culture as part of standard care. Additionally, a blood sample will be collected from the umbilical cord for MC. In case of a suspicion of sepsis not directly postpartum, an additional blood sample will be taken for MC analysis, directly following sampling for conventional culture, implying no extra phlebotomy. Main study parameters/endpoints: The main study parameter is the discordance in positive and negative outcomes of MC compared to outcomes of conventional blood culture. As the diagnostic accuracy of the conventional blood culture (the current gold standard) is being questioned, the predictive value of MC versus conventional blood culture towards clinical sepsis will also be tested.
High-risk pregnancies often require long-term hospitalization or outpatient maternal and/or fetal monitoring, placing a burden on patients, hospital resources and society. The demand for intensified pregnancy surveillance and interventions is increasing, due to the increased prevalence of risk factors like obesity and advanced maternal age, as well as altered guidelines resulting in increasing labor induction rates.The main aims of the HOME study (Home monitoring of pregnancies at risk) are to assess if home monitoring of selected high-risk pregnancies for maternal and fetal wellbeing is feasible, safe (in a clinical trial), cost-efficient, and simultaneously empowers the users.
