  • Patent number: 10295536
    Abstract: Clostridium difficile disease involves a range of clinical presentations ranging from mild to self-limiting diarrhea to life-threatening pseudomembranous colitis and megacolon. Cases of C. difficile are treated differently depending on severity of disease. Mild and moderate cases may be treated with metronidazole while moderate-to-severe and relapsing cases are often treated with vancomycin or fidaxomicin. The presence of C. difficile disease is detected using a biomarker panel that includes C. difficile antigen (GDH), toxins A and B, and fecal lactoferrin. In patients suspected of C. difficile disease, if GDH is detected indicating the presence of C. difficile, and then toxins A and/or B are detected to indicate toxigenic C. difficile and support a diagnosis of C. difficile-associated disease, fecal lactoferrin concentrations are measured to determine severity of the disease by indicating the amount of intestinal inflammation.

  • Patent number: 10295535
    Abstract: Clostridium difficile disease involves a range of clinical presentations ranging from carrier status with other causes of symptoms to mild and self-limiting diarrhea to life-threatening pseudomembranous colitis and megacolon. Cases of C. difficile are treated differently depending on the presence and then the severity of disease. Patients that are carriers may not receive treatment with concern of causing the disease. Mild to moderate cases may be treated with metronidazole while severe and relapsing cases are often treated with vancomycin or fidaxomicin. Current molecular assays are highly sensitive for detecting toxigenic C. difficile and cannot rule out carrier status. Utilization of a biomarker panel that includes C. difficile antigen (GDH), toxins A and B, and fecal lactoferrin allows clinicians to differentiate between a carrier state and active state of C. difficile and allows for monitoring to evaluate the effectiveness of treatment.

  • Patent number: 4698546
    Abstract: The present invention provides apparatus for forming electron beams, which may be advantageously employed in many applications, for example in display devices or thyratrons. A cathode member has a hole in its front surface. All the surfaces of the cathode member, except for the wall and base of the holes, are covered in an electrically insulating material such as glass. The cathode member and an anode member are contained within an envelope which also contains a gas filling. On application of a suitably high voltage between the cathode and anode members an electron beam is formed extensive in a direction away from the hole. The anode member may be located behind the front surface of the cathode member, and an electron beam still forms in front of the front surface.
