Randomized Controlled TrialSurgical treatment for both-column acetabular fractures using pre-operative virtual simulation and three-dimensional printing techniques.
Surgical treatment of both-column acetabular fractures is challenging because of the complex acetabular fracture patterns and the curved surface of the acetabulum. Seldom study has compared the application of three-dimensional (3D) printing technology and traditional methods of contouring plates intra-operatively for the surgical treatment of both-column acetabular fractures. We presented the use of both 3D printing technology and a virtual simulation in pre-operative planning for both-column acetabular fractures. We hypothesized that 3D printing technology will assist orthopedic surgeons in shortening the surgical time and improving the clinical outcomes. ⋯ No.ChiCTR1900028230; http://www.chictr.org.cn.

Meta AnalysisSpecial prognostic phenomenon for patients with mid-range ejection fraction heart failure: a systematic review and meta-analysis.
Clinical features and outcomes of heart failure (HF) with mid-range ejection fraction (HFmrEF) remain controversial. Thus, we systematically reviewed literatures of clinical research to assess and analyze characteristics and prognosis of patients with HFmrEF. ⋯ This systematic review and meta-analysis compared features and prognosis between patients with HFmrEF and HFpEF, HFrEF by HRs. There appeared a special "separation phenomenon" showing rates of endpoints were inconsistent with their hazards in patients with HFmrEF compared with HFpEF patients.

ReviewResearch progress on the etiology and pathogenesis of adolescent idiopathic scoliosis.
Etiology of adolescent idiopathic scoliosis (AIS), a complicated three-dimensional spinal deformity with early-onset, receives continuous attention but remains unclear. To gain an insight into AIS pathogenesis, this review searched PubMed database up to June 2019, using key words or medical subject headings terms including "adolescent idiopathic scoliosis," "scoliosis," "pathogenesis," "etiology," "genetics," "mesenchymal stem cells," and their combinations, summarized existing literatures and categorized the theories or hypothesis into nine aspects. These aspects include bone marrow mesenchymal stem cell studies, genetic studies, tissue analysis, spine biomechanics measurements, neurologic analysis, hormone studies, biochemical analysis, environmental factor analysis, and lifestyle explorations. These categories could be a guidance for further etiology or treatment researches to gain inspiration.

A new tool for comprehensive geriatric assessment in elderly patients with acute myeloid leukemia: a pilot study from China.
Acute myeloid leukemia (AML) is a common type of hematological malignancy in elderly people. Geriatricians have developed comprehensive geriatric assessment (CGA) methods for elderly patients; however, the tools used for CGA in AML are not uniform. Thus, we aimed to validate the instrumental activities of daily living (IADL) scales, age, comorbidities (Charlson Comorbidity Index), and albumin (IACA) index, which is a new tool for CGA, in elderly patients with AML. ⋯ We suggest that the IACA index might be a simple and effective tool for comprehensive geriatric assessment in elderly AML patients.

Role of serum cystatin C in the prediction of contrast-induced nephropathy after intra-arterial interventions.
The diagnosis of contrast-induced nephropathy (CIN) is usually based on changes in serum creatinine (sCr). However, sCr has poor sensitivity as a biomarker of kidney injury. The aim of this study was to investigate the usefulness of serum cystatin C (sCysC) to predict CIN after intra-arterial interventions. ⋯ SCysC is an appropriate biomarker to predict the occurrence of CIN. Baseline sCysC before an intervention is useful to obtain a preliminary estimate of the risk of CIN. A 48-h cut-off value of sCysC of 0.99 mg/L after an endovascular procedure may help to rule out patients at lower risk of CIN.
