A better understanding of the risks and reasons for unplanned readmission is an essential component in reducing costs in the health care system and in optimizing patient safety and satisfaction. The reasons for unplanned readmission vary between different disciplines and procedures. The aim of this study was to identify reasons for readmission in view of different diagnoses in cranial neurosurgery. ⋯ Reasons and predictors for an unplanned readmission differ considerably among the index diagnosis groups. In addition to well-known reasons for readmission, we identified social indication, meaning a lack of home care, which is particularly prevalent in oncologic and elderly patients. A transitional care program could benefit these vulnerable patients.

Oblique lumbar interbody fusion (OLIF) is useful as surgical treatment of degenerative lumbar disease. However, revision surgery has often resulted in worse surgical outcomes than primary surgery. Thus, we compared the usefulness of OLIF as primary surgery (PS) versus revision surgery (RS). ⋯ Most radiological outcomes were similar between the RS and PS groups, with no differences in complications or the requirement for additional posterior decompression. However, OLIF resulted in relatively poor clinical outcomes when used as RS. Thus, revision spine surgery tends to result in poor outcomes compared with those of primary spine surgery; however, OLIF can be a tolerable option for revision spine surgery.

We used dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) technology and its perfusion parameters to diagnose central glioma high-grade glioma (HGG), primary central nervous system glioma low-grade glioma (LGG), brain metastases, and meningioma and make differential diagnoses. ⋯ DCE-MRI can distinguish HGG and LGG more accurately, of which t-Ktrans value has higher specificity and sensitivity, although the difference of t-Ve value between PCNSL and HGG is statistically significant but the sensitivity and specificity are not high; the p-Ktrans value and p-Kep value of metastatic tumors are lower than HGG and have higher specificity, but meningiomas and HGG and PCNSL, meningiomas and metastases are not accurate identification.

To investigate the clinical characteristics and factors affecting the prognosis of myxopapillary ependymoma (MPE). ⋯ Our findings suggest that the degree of surgical resection was a key factor that affected the prognosis and neurologic function of the included patients with MPE.

To find out the bioelectric signal discriminative features of different acupoints at the same time and at the same acupoint, and then analyze these differences to determine the type of acupuncture points and assist in judging the patient's condition, a hardware system was designed that can collect subcutaneous potential information of acupoints. Then, the changes of ultrasonic images were analyzed after acupuncture at Zu San Li, as well as the influence of acupuncture at Zu San Li on vagal nerve activity. The hardware system is composed of 4 parts: an analog circuit module, a digital circuit module, a power module, and a host personal computer. ⋯ After acupuncture at Zu San Li, the vagal activity was increased and the balance ratio of sympathetic vagal activity was reduced. Part of the potential frequency of the acupoint is extremely active, which is the response potential of the subcutaneous induction tissue at the acupoint, which proved the feasibility of collecting electric signals around the acupoints in this kind of hardware system. It is of great significance to diagnose the disease according to the characteristics of acupoint electric signals.
