Objective: This study is to assess an innovative technique - a vertebral osteotome (VO) combined with side-opening injection cannula for percutaneous vertebroplasty (PVP).
Methods: A retrospective study by propensity score matching. From January 2016 to April 2016, 63 patients who were diagnosed with monosegmental osteoporotic vertebral compression fracture received the innovative technique. The epidemiologic data, surgical indexes, and recovery outcomes were collected in the follow-up period. Propensity score matching identified 63 pairs form historical controls by traditional unilateral PVP approach in 2015 using six independent variables: age, sex, preoperative visual analog score (VAS), Oswestry Disability Index (ODI), body mass index, and bone mineral density.
Results: The surgical duration and cement distribution were longer and larger in patients by VO method. Besides, postoperative VAS and ODI in the VO group were lower than those in the control group. However, there were no differences in radiation exposure times, improvement of Cobb angle, cement leakage, or adjacent vertebral fracture between two groups. Cement volume in the VO group was less than that in the control group.
Conclusion: This new innovative technique makes PVP safe and effective. Although it lasts longer, the restoration rate of vertebral height and cement distribution can be improved, which contributes to a better pain relief.

The pathogenic oomycete Pythium insidiosum causes a fatal infectious illness known as pythiosis, impacting humans and certain animals in numerous countries in the tropics and subtropics. Delayed diagnosis is a primary factor contributing to the heightened morbidity and mortality associated with the disease. Several new serodiagnostic methods have been developed to improve the identification of pythiosis.

Purpose: The management of soft tissue sarcoma (STS) at reference centers with specialized multidisciplinary tumor boards (MTB) improves patient survival. The German Cancer Society (DKG) certifies sarcoma centers in German-speaking countries, promoting high standards of care. This study investigated the variability in treatment recommendations for localized STS across different German-speaking tertiary sarcoma centers.

Since its discovery, carbon quantum dots (CDs) have been widely applied in cell imaging, drug delivery, biosensing, and photocatalysis due to their excellent water solubility, chemical stability, fluorescence stability biocompatibility, low toxicity, and preparation cost. However, the low fluorescence yield and poor surface structure limit the application of CDs. Heteroatom doping is considered an ideal method to improve CDs' optical and electrical properties.
