Modelling the Dependence of the UK Stock Market on the US Stock Market: A Need for Multiple Regimes
A J Khadaroo 한양대학교 경제연구소 2013 JOURNAL OF ECONOMIC RESEARCH Vol.18 No.2
Through the use of regime-switching models, recent empirical research has essentially shown that the dynamics of stock returns depend on the state of one stock market. The present paper extends this analytical framework by allowing the dynamics of returns to depend on the joint-states of two different stock markets. Such an extension is natural given the globalisation of financial markets and the rapid transmission of news from one international stock market to another. In an application involving the S&P500, the FTSE100 and the NIKKEI225 over the period January 1984 – October 2003, UK stock returns are found to depend on the joint-states of the US and UK stock markets three months back. Moreover the contemporaneous dependence of UK stock returns on US stock returns increases with a rising US market and a falling UK market but decreases with a falling US market and a rising UK market. This is consistent with a ‘rapport de force’ effect whereby the relative strengths of the US and UK stock markets matter in determining the degree of contemporaneous dependence of the UK stock market on the US stock market.

Risk Factors for Duodenal Stump Leakage after Laparoscopic Gastrectomy for Gastric Cancer
Lihu Gu,Kang Zhang,Zefeng Shen,Xianfa Wang,Hepan Zhu,Junhai Pan,Xin Zhong,Parikshit Asutosh Khadaroo,Ping Chen 대한위암학회 2020 Journal of gastric cancer Vol. No.
Purpose: Duodenal stump leakage (DSL) is a potentially fatal complication that can occur after gastrectomy, but its underlying risk factors are unclear. This study aimed to investigate the risk factors and management of DSL after laparoscopic radical gastrectomy for gastric cancer (GC). Materials: and Methods Relevant data were collected from several prospective databases to retrospectively analyze the data of GC patients who underwent Billroth II (B-II) or Roux-en-Y (R-Y) reconstruction after laparoscopic gastrectomy from 2 institutions (Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, and HwaMei Hospital, University of Chinese Academy of Sciences). The DSL risk factors were analyzed using univariate and multivariate analysis regression. Results: A total of 810 patients were eligible for our analysis (426 with R-Y, 384 with B-II with Braun). Eleven patients had DSL (1.36%). Body mass index (BMI), elevated preoperative C-reactive protein (CRP) level, and unreinforced duodenal stump were the independent risk factors for DSL. DSL was diagnosed in 2–12 days, with a median of 8 days. Seven patients received conservative treatment, 3 patients received puncture treatment, and only 1 patient required reoperation. All patients recovered successfully after treatment. Conclusions: The risk factors of DSL were BMI ≥24 kg/m2, elevated preoperative CRP level, and unreinforced duodenal stump. Nonsurgical treatments for DSL are preferred.

This study aimed to investigate the risk factors and management of DSL after laparoscopic radical gastrectomy for gastric cancer (GC). Materials and Methods: Relevant data were collected from several prospective databases to retrospectively analyze the data of GC patients who underwent Billroth II (B-II) or Rouxen-Y (R-Y) reconstruction after laparoscopic gastrectomy from 2 institutions (Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, and HwaMei Hospital, University of Chinese Academy of Sciences). The DSL risk factors were analyzed using univariate and multivariate analysis regression. Results: A total of 810 patients were eligible for our analysis (426 with R-Y, 384 with B-II with Braun).

All patients recovered successfully after treatment. Conclusions: The risk factors of DSL were BMI ≥24 kg/㎡, elevated preoperative CRP level, and unreinforced duodenal stump. Nonsurgical treatments for DSL are preferred.
