The purpose of this study is to examine the impacts of China’s outward foreign direct investment (OFDI) in ‘Belt and Road’(B&R) countries on two domestic problems: overcapacity in the Old Economy, and inter-regional disparities. Since the B&R initiative was announced in 2013, China has been increasing investment in B&R countries. However, it is too early to conclude that China has made significant progress in reducing overcapacity and inter-regional disparities through OFDI, for the following reasons. (i) The growth of China’s regional economies remains dependent on domestic investment due to promotion competition between local officials, although investment efficiency has been decreasing since the late 2000s. (ii) The productivity of the enterprises that undertake OFDI is higher than those that do not. In China, enterprises located in developed coastal areas tend to undertake more OFDI. Inland areas usually have enterprises that are more inefficient and local governments rarely allow them to exit the markets. For the near future, firms in coastal areas will seize the investment opportunities in B&R countries.

Purpose: Small bowel obstruction (SBO) remains a common complication after pelvic or abdominal surgery. However, the risk factors for SBO in ulcerative colitis (UC) surgery are not well known. The aim of the present study was to clarify the risk factors associated with SBO after ileal pouch-anal anastomosis (IPAA) with a loop ileostomy for patients with UC. Methods: The medical records of 96 patients who underwent IPAA for UC between 1999 and 2011 were reviewed. SBO was confirmed based on the presence of clinical symptoms and radiographic findings. The patients were divided into 2 groups: the SBO group and the non-SBO group. We also analyzed the relationship between SBO and computed tomography (CT) scan image parameters. Results: The study included 49 male and 47 female patients. The median age was 35.5 years (range, 14–72 years). We performed a 2- or 3-stage procedure as a total proctocolectomy and IPAA for patients with UC. SBO in the pretakedown of the loop ileostomy after IPAA occurred in 22 patients (22.9%). Moreover, surgical intervention for SBO was required for 11 patients. In brief, closure of the loop ileostomy was performed earlier than expected. A multivariate logistic regression analysis revealed that the 2-stage procedure (odds ratio, 2.850; 95% confidence interval, 1.009–8.044; P = 0.048) was a significant independent risk factor associated with SBO. CT scan image parameters were not significant risk factors of SBO. Conclusion: The present study suggests that a 2-stage procedure is a significant risk factor associated with SBO after IPAA in patients with UC.

IMPACT OF RETAILERS’ GOAL-DIRECTED MOTIVATIONAL PROMOTIONS ON CUSTOMERS’ PARTICIPATION

Many retailers and food service providers offer programs as part of their loyalty programs in which customers are given stamps for each purchase of a qualifying product or service and redeemed for a reward once a certain number of stamps have been accumulated. We identify which stimuli in such goal-directed motivational promotions induce customers to participate in the program.

Objective: Owing to the potential benefits of minimally invasive hysterectomy for endometrial cancer, the practice pattern has recently shifted in Japan. This study examined the trends in minimally invasive surgery (MIS) in patients with endometrial cancer in Japan. Methods: This retrospective observational study examined the Japan Society of Obstetrics and Gynecology Tumor Registry database between 2015–2019. This study examined the time-specific proportion change and predictors of MIS use in initial endometrial cancer treatment in Japan, and compared it with the use of abdominal surgery. Additionally, the association between hospital surgical treatment volume and MIS use was examined. Results: A total of 14,059 patients (26.5%) underwent minimally invasive hysterectomy, and 39,070 patients (73.5%) underwent abdominal hysterectomy in the study period. Patients who underwent MIS were more likely to be treated at high-volume centers, younger, central, or western Japan residents, registered in recent years, and had a tumor with stage I disease, type 1 histology, and less myometrial invasion (all adjusted p<0.05). The proportion of MIS treatments increased from 19.1% in 2015 to 34.3% in 2019 (p<0.001). On multivariable analysis, treatment at high-volume centers was a contributing factor for MIS (adjusted odds ratio=3.85; 95% confidence interval=3.44–4.30). MIS at high-volume centers increased significantly from 24.8% to 41.0% (p<0.001) during the study period, whereas MIS at low-volume centers remained at median 8.8%. Conclusion: MIS has increased significantly in recent years, accounting for nearly 34% of surgical management of endometrial cancer in Japan. High-volume treatment centers take the lead in performing MIS.

Background/AimsNatural history of chronic intestinal pseudo-obstruction (CIPO), a rare disease characterized by episodes of non-mechanical obstruction, is unclear in adults. This study evaluates the clinical course of CIPO and palliative care needs of patients. MethodsFrom October 2010 to September 2021, 74 patients who underwent cine MRI and had a definitive diagnosis of CIPO were prospectively included. We investigated disease etiology and outcomes, age at onset, nutritional status at consultation (body mass index and serum albumin), hydrogen breath test results, and total parenteral nutrition (TPN) during the disease course. ResultsForty-seven patients (64%) were women, with a mean age of 44 years at onset and 49 years at diagnosis. Primary CIPO was observed in 48 patients (65%). Secondary CIPO was observed in 26 cases (35%), of whom 18 (69%) had scleroderma. The mean body mass index, serum albumin level, and hydrogen breath test positivity rate were 17 kg/m2, 3.8 mg/dL, and 60%, respectively. TPN and invasive decompression therapy were required by 23 (31%) and 18 (24%) patients, respectively. Intestinal sterilization was performed in 51 (69%) patients and was effective in 33 (65%); of these, 28 (85%) were taking metronidazole. Seven (9%) patients used opioids. There were 9 deaths (12%), including 5 (56%) from infection and 2 (22%) from suicide. Of the deaths, 6 (67%) and 4 (44%) underwent TPN management and decompression therapy, respectively. Fifty-one patients (69%) wanted palliative care. ConclusionCIPO is a rare, severe, and under-recognized disease. Standardization of treatment strategies, including palliative care and psychiatric interventions, is desired.
