Almost half of growing rod (GR) patients that undergo final fusion (FF) have an extension of instrumented levels. The purpose of this study was to review sagittal plane radiographic parameters of patients with distal extension of instrumented levels at FF to those whose levels remained the same. Radiographs were assessed preoperatively, after GR insertion/first lengthening, following GR treatment before FFs, and after FF. Measurements included sagittal balance, lumbar lordosis, thoracic kyphosis, and distal junction angle (DJA)...

BACKGROUND: Novel agents are changing the treatment of relapsed or refractory Hodgkin lymphoma (HL). Nevertheless, high-dose chemotherapy and autologous stem-cell transplantation (ASCT) are considered standard of care in eligible patients. To identify patients who could benefit most from novel therapeutic approaches, we investigated a comprehensive set of risk factors for survival after ASCT. METHODS: In this multinational prognostic multivariable modeling study, 23 potential risk factors (RF) were retrospectively evaluated in HL patients from nine prospective trials with multivariable Cox proportional hazards regression analyses (part I)...

BACKGROUND: Exposure to ionizing radiation for diagnostic purposes is inevitable in modern medicine. The therapeutic application of irradiation is highly effective against cancer; however, this implies exposure of normal tissue structures to significant doses of radiation. Diagnostic or therapeutic exposure to ionizing radiation can result in tissue changes and tumor induction in the long term. Knowledge of the biological mechanisms underlying these effects is essential for individualization of the application...

STUDY DESIGN: Retrospective analysis of 16 patients. SUMMARY OF BACKGROUND DATA: The lumbar split fracture-dislocation is a rare but severe injury, which is type C1.2.1 fracture in the Association for the Study of Internal Fixation spine fracture classification. The axial compressive and torsional force shattered the vertebral body into 2 halves and displaced them rotationally. This kind of fracture is so highly unstable that the treatment is very challenging. PURPOSE: The purpose of this study was to report and compare on clinical outcome and complications of patients with lumbar split fracture-dislocation which had been treated either short-segment or long-segment posterior fixation and anterior fusion...

Kidney diseases are a public health problem worldwide; the mortality rate is between 50 and 80%. Available therapies include replacement function by dialysis or transplant, associated with a high morbidity and mortality; kidney transplantation is limited by the shortage of donor organs, immune rejection and lifelong treatment with immunosuppressive. Likewise, none of these treatments compensates all kidney functions. There is a great concern in developing more effective therapies with the ability to replace the wide range of renal functions, so that, new researches on developing therapeutic strategies have focused on regenerative medicine, science that includes artificial creation of tissues and organs, in order to repair or replace a tissue or organ function...

BACKGROUND: Curcumae Longae Rhizoma is one of the commonly used traditional Chinese medicines, which has multiple biological activities such as relieving stagnation and stasis, pain alleviation, curing amenorrhea and wounds. However, its main active component-curcumin has poor absorption and very fast metabolism in body. To solve this problem, Piper nigrum was introduced for its ability to strengthen bioavailability of other compounds. PURPOSE: In most cases of TCM couplets, all ingredients were prepared and taken simultaneously, which in our opinion did not take full advantage of their interactions...

Glioblastoma multiforme (GBM) is the most aggressive intracranial tumor characterized with infaust prognosis. Despite advances in neurosurgical and radiotherapeutic techniques and chemotherapy, the median overall survival ranges between 12-15 months from diagnosis. The main cause of treatment failure is considered the presence of tumor cells resistant to conventional therapy, mainly radiotherapy. MicroRNAs (miRNAs) are small, non-coding RNAs that function as post-transcriptional regulators of gene expression and have been repeatedly proven to play important roles in pathogenesis and biological features of many cancers, including GBM and its radioresistant phenotype...
