Abstract: In general, the present disclosure is directed to systems and methods of evaluating a subject's risk of one or more complications associated with pelvic organ prolapse surgery. The method comprising: obtaining, by a computing system comprising one or more computing devices, sample data associated with the subject; obtaining, by a computing system comprising one or more computing devices, medical record data associated with the subject; inputting, by the computing system, the sample data into a machine-learned surgical model; receiving, by the computing system as an output of the machine-learned surgical model, one or more predictions of post-surgical complications of mesh exposure through a vaginal wall associated with the subject; and performing a pelvic organ prolapse repair surgery on the subject.

Abstract: A small-sized air cushion vehicle includes a hull having a planar bottom surface with an upstanding lower flange disposed at a predetermined angle with respect to the bottom surface. A plurality of apertures are formed in the peripheral flange. An upper hull is mounted on the lower hull and includes a centrally located occupant area. The upper hull engages the lower hull to form a hollow plenum chamber extending internally around the periphery of the upper and lower hulls. A plurality of inflatable members are mounted on the exterior surface of the peripheral flange and are each disposed in fluid flow communication with an aperture in the peripheral flange. A motor driven fan is mounted on the upper hull and directs a portion of an air stream rearward of the vehicle to propel the vehicle and another portion of the air stream into the plenum chamber to inflate the inflatable members and to lift the vehicle a short distance above an underlying surface.

Abstract: A small sized air cushion vehicle includes a hull having a planar bottom surface with an upstanding lower flange disposed and extending upwardly at an angle of between 24.degree. and 30.degree. with respect to the planar bottom surface of the hull. A hollow plenum extends through the periphery of the hull. Apertures are formed in the upstanding lower flange of the hull and disposed in fluid flow communication with corresponding apertures in a plurality of inflatable members which are attached to the flange of the hull. Each inflatable member includes a downwardly extending aperture which directs air flow from the hollow plenum in the hull through each of the inflatable members to lift the vehicle a short distance above an underlying surface as well as providing forward or sideways propulsion. A steering mechanism is mounted rearward of the fluid propulsion source to control the direction of movement the vehicle.
