Randomized Controlled Trial
Efficacy and Safety of Stroke Volume Variation-Guided Fluid Therapy for Reducing Blood Loss and Transfusion Requirements During Radical Cystectomy: A Randomized Clinical Trial.
Radical cystectomy, which is performed to treat muscle-invasive bladder tumors, is among the most difficult urological surgical procedures and puts patients at risk of intraoperative blood loss and transfusion. Fluid management via stroke volume variation (SVV) is associated with reduced intraoperative blood loss. Therefore, we evaluated the efficacy and safety of SVV-guided fluid therapy for reducing blood loss and transfusion requirements in patients undergoing radical cystectomy. ⋯ There were no significant differences in postoperative outcomes between the two groups. SVV-guided fluid therapy (SVV maintained at 10%-20%) can reduce blood loss and transfusion requirements in patients undergoing radical cystectomy without resulting in adverse outcomes. These findings provide useful information for optimal fluid management during radical cystectomy.

Observational Study
Experience of Intraoperative Cell Salvage in Surgical Correction of Spinal Deformity: A Retrospective Review of 124 Patients.
The effect of intraoperative cell salvage (ICS) in surgical correction of spinal deformity remained controversial. This study was to quantitatively demonstrate its effect. In all, 124 patients having ICS in surgical correction of spinal deformity were included. ⋯ No severe complications related to ICS were observed. In summary, ICS could decrease the amount of allogenic transfusion in surgical correction of spinal deformity. However, in terms of reducing prevalence of allogenic transfusion, it had a protective effect only in patients with small blood loss.

Spontaneous intracranial hypotension (SIH) is characterized by postural headache because of low cerebrospinal fluid (CSF) pressure. Brain magnetic resonance imaging (MRI) and radioisotope (RI) cisternography can be used to identify the site of a CSF leakage. Although autologous epidural blood patch (EBP) is a very effective treatment modality, some patients require a repeat autologous EBP. ⋯ Patients with early bladder activity on RI cisternography had a tendency to need a higher number of autologous EBPs. Only sagging of the brain and no other variables showed a statistically significant negative correlation with the number of autologous EBPs. The response to autologous EBP may be related to the radiologic findings of early bladder activity on RI cisternography and sagging of the brain on MRI.

Atrial fibrillation (AF) is one of the most frequent arrhythmias in clinical practice. Previous studies have reported the influence of AF on patients with heart failure (HF). The effect of AF on the non-HF critically ill patients in a medical intensive care unit (ICU) remains largely unclear. ⋯ Multivariate logistic regression analysis demonstrated that AF independently increased the risk of weaning failure [adjusted odds ratio (AOR), 3.268; 95% confidence interval (CI), 1.254-8.517; P = 0.015]. Furthermore, the AF patients were found to be independently associated with a high rate of ventilator dependence (log rank test, P = 0.026), prolonged total ventilator use (AOR, 1.979; 95% CI, 1.032-3.794; P = 0.040), increased length of ICU stay (AOR, 2.256; 95% CI, 1.049-4.849; P = 0.037), increased length of hospital stay (AOR, 2.921; 95% CI, 1.363-6.260; P = 0.006), and increased ICU mortality (AOR, 4.143; 95% CI, 1.381-12.424; P = 0.011). AF on ICU admission is an independent risk factor for weaning failure and significantly associated with poor hospital outcome in non-HF mechanically ventilated patients in a medical ICU.

Observational Study
Identification of High-Risk Subgroups of Patients With Oral Cavity Cancer in Need of Postoperative Adjuvant Radiotherapy or Chemo-Radiotherapy.
Patients with oral cavity squamous cell carcinoma (OSCC) undergoing surgery are recommended to receive adjuvant radiation therapy with or without chemotherapy if there are unfavorable prognostic factors. A positive resection margin (PRM) and extra-capsular extension (ECE) of lymph nodes are well-known major prognostic factors. However, there is no agreement on whether oral cavity cancer patients should receive postoperative chemo-radiotherapy (CCRT) if they present with other risk factors or a combination of 2 or more risk factors. ⋯ For 179 patients with at least 3 minor prognostic factors and/or at least 1 major risk factor, patients receiving postoperative CCRT showed significantly better 5-year LRC, DFS, and OS compared with post-OP RT or surgery alone. Patients with 2 minor risk factors should receive postoperative RT. For patients with PRM, ECE, or >2 minor risk factors, postoperative CCRT is recommended.
