Systems and methods for assessing fluids from a patient are disclosed. The system includes a receptacle including an inlet port, an outlet port, and a third port; a valve system in fluidic communication with the receptacle; and one or more features in the receptacle to aid in optical imaging of fluids. The system has a fill mode and a flush mode. In the fill mode, the valve system directs suction from a vacuum source through the third port into the receptacle, thereby drawing fluid through the inlet port into the receptacle. In the flush mode, the valve system directs suction from the vacuum source through the outlet port, thereby drawing fluid through the outlet port out of the receptacle. Fluid-related information such as, for example, concentration of a blood component, may be estimated based on images of fluids in the receptacle.

Disclosed herein is a method of providing a metabololipidomic profile and SPM signature on the progress of the innate host defense response following blood clotting. The method can include the step of taking one or more measurements in a patient's blood sample, wherein the sample is obtained during the time-course of clotting or coagulation or following clotting or coagulation, of pro-thrombotic and pro-inflammatory mediators (eicosanoids) and specialized pro-resolving mediators SPMs. From these measurements, a personalized metabololipidomic profile can be obtained. By comparing the measurement to that taken from normal or reference blood, a comparison profile can be developed. The profile comparison profile can then be used to make a medical or therapeutic decision.

Tissue access devices and methods of using the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring. The spring can be biased to move the sensor from a sensor first configuration to a sensor second configuration when a force applied by the sensor first surface against a non-sensor surface changes from a first force to a second force less than the first force. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.

Disclosed are methods and apparatuses for treating a pregnancy related hypertensive disorder, such as pre-eclampsia and eclampsia, using ex vivo treatment with an anti-sFlt-1 antibody and an anti-sEng antibody bound to a solid support in order to reduce blood levels of sFlt-1 and sEng. The present disclosure relates to methods, systems, devices, and apparatuses for treating pregnancy-related hypertensive disorders such as pre-eclampsia and eclampsia.
