The invention provides apparatus and methods for home or other remote delivery of health care that gather subjective and objective measures of patient health and treatment, analyzing them (e.g., correlating them with one another and / or with norms) and reporting them to aid in on-going patient diagnosis and treatment (both on acute and chronic bases), as well as to aid physicians, nurses and other caregivers in decision support, monitoring treatment compliance, facilitating regulatory compliance, billing, and so forth. Thus, for example, in some aspects a health care delivery device comprising a medical treatment apparatus, such as a home hemodialysis or home peritoneal dialysis unit, that is coupled to a processor. The processor generates patient queries in connection with treatments rendered by the dialysis equipment (or other treatment apparatus). The queries are directed, at least in part, to subjective topics, such as the state of the patient's mental health and well being, quality of life, degrees of pain, views on success of therapy, and so forth. They are presented on an LCD screen or other output device coupled to the processor to elicit responses on a keyboard or other input device, also coupled to the processor.

A decision-support system and computer implemented method automatically measures the midline shift in a patient's brain using Computed Tomography (CT) images. The decision-support system and computer implemented method applies machine learning methods to features extracted from multiple sources, including midline shift, blood amount, texture pattern and other injury data, to provide a physician an estimate of intracranial pressure (ICP) levels. A hierarchical segmentation method, based on Gaussian Mixture Model (GMM), is used. In this approach, first an Magnetic Resonance Image (MRI) ventricle template, as prior knowledge, is used to estimate the region for each ventricle. Then, by matching the ventricle shape in CT images to the MRI ventricle template set, the corresponding MRI slice is selected. From the shape matching result, the feature points for midline estimation in CT slices, such as the center edge points of the lateral ventricles, are detected. The amount of shift, along with other information such as brain tissue texture features, volume of blood accumulated in the brain, patient demographics, injury information, and features extracted from physiological signals, are used to train a machine learning method to predict a variety of important clinical factors, such as intracranial pressure (ICP), likelihood of success a particular treatment, and the need and / or dosage of particular drugs.

The invention relates to a novel cardiac valve implantation instrument with an anchoring device. The novel cardiac valve implantation instrument comprises a cardiac valve prosthesis, at least two sets of anchoring needles and at least two sets of anchoring needle releasing devices detachably connected with the cardiac valve prosthesis. The far ends of the anchoring needles are in preset shapes, the anchoring needle releasing devices comprise conveying pipes, push rods and hollow guide rails, the guide rails are arranged in the conveying pipes in advance and can move towards the far ends of the conveying pipes, rigid sections are arranged at the far ends of the guide rails, the anchoring needles are arranged in the guide rails in advance in an extension state, the push rods are arranged in the conveying pipes and located at the near ends of the anchoring needles, the far ends of the anchoring needle releasing devices are in preset shapes, the far ends of the conveying pipes can be overall bent or partially bent, the guide rails and the anchoring needles can move towards the far ends of the conveying pipes under the action of external force, and the cardiac valve prosthesis is fixedly arranged between the autologous tissue and the anti-falling ends of the anchoring needles. The novel cardiac valve implantation instrument can achieve accurate locating and firm anchoring, and the treatment success rate is improved.
