Hydraulic Efficiency of Flood Detention Pools Evaluated by Means of Mathematical Simulation

The hydraulic efficiency to secure optimization of the flood detention pool system will be treated through mathematical simulation. The mathematical model is approximated by the point-sink virtually located at the center of the deversoir section. Numerical computations show that the optimization of the system in hydraulic efficiency will be given through a combination of the deversoir length and the initial diversion discharge. Furthermore, it is seen the whole pool volume will be nearly constant for any possible combination

Occult Vertebral Fracture (OVF) in Patients Who Underwent Hepatectomy for Colorectal Liver Metastasis: Strong Association with Oncological Outcomes

Aim: The impact of occult vertebral fracture (OVF) on oncological outcomes after surgery has not been investigated, although its significance in orthopedics has been much debated recently. We evaluated the prognostic significance of OVF on the long-term outcomes of patients with colorectal liver metastases (CRLM) after hepatectomy. Methods: We included 140 patients with CRLM who underwent hepatectomy. OVF was identified using quantitative measurement and preoperative sagittal computed tomography image reconstruction from the 11th thoracic vertebra to the 5th lumber vertebra. Results: OVF was identified in 48 (34%) of the patients. In multivariate analysis, lymph node metastases (p p = 0.02), extrahepatic lesions (p p p = 0.04), and curability 1 or 2 (p p p = 0.02), and OVF (p < 0.01) were independent and significant predictors of overall survival. A higher age, adjuvant chemotherapy for a primary lesion before metachronous liver metastases, osteopenia, and hypoalbuminemia were independent risk factors for OVF. Conclusions: The evaluation of preoperative OVF is a useful prognostic factor for risk stratification and clinical decision-making for patients with CRLM

The impact of C‐reactive protein‐albumin‐lymphocyte (CALLY) index on the prognosis of patients with distal cholangiocarcinoma following pancreaticoduodenectomy

Abstract Aim The C‐reactive protein (CRP)‐albumin‐lymphocyte (CALLY) index is a novel inflammation‐based biomarker, which has been associated with long‐term outcomes in patients with hepatocellular carcinoma. We aimed to investigate whether the CALLY index can predict the prognosis for distal cholangiocarcinoma after pancreaticoduodenectomy. Methods The study comprised 143 patients who had undergone primary pancreaticoduodenectomy for distal cholangiocarcinoma between 2002 to 2019. The CALLY index was defined as (albumin × lymphocyte)/ (CRP × 104). We investigated the association of CALLY index with disease‐free survival and overall survival by univariate and multivariate analyses. Results Eighty‐seven (61%) patients had a preoperative CALLY index <3.5. In multivariate analysis, obstructive jaundice drainage (P < .01), poorly differentiated tumor (P < .01), and CALLY index<3.5 (P = .02) were independent predictors of disease‐free survival, while obstructive jaundice drainage (P < .01), poorly differentiated tumor (P < .01), and CALLY index <3.5 (P = .02) were independent predictors of overall survival. Conclusion The CALLY index may be an independent and significant indicator of poor long‐term outcomes in patients with distal cholangiocarcinoma after pancreaticoduodenectomy, suggesting the importance of comprehensive assessment for inflammatory status
