ABSTRACT

@#Objective     To explore the causes of conversion to thoracotomy in patients with minimally invasive esophagectomy (MIE) in a surgical team, and to obtain a deeper understanding of the timing of conversion in MIE. Methods     The clinical data of patients who underwent MIE between September 9, 2011 and February 12, 2022 by a single surgical team in the Department of Thoracic Surgery of the Fourth Hospital of Hebei Medical University were retrospectively analyzed. The main influencing factors and perioperative mortality of patients who converted to thoracotomy in this group were analyzed. Results     In the cohort of 791 consecutive patients with MIE, there were 520 males and 271 females, including 29 patients of multiple esophageal cancer, 156 patients of upper thoracic cancer, 524 patients of middle thoracic cancer, and 82 patients of lower thoracic cancer. And 46 patients were converted to thoracotomy for different causes. The main causes for thoracotomy were advanced stage tumor (26 patients), anesthesia-related factors (5 patients), extensive thoracic adhesions (6 patients), and accidental injury of important structures (8 patients). There was a statistical difference in the distribution of tumor locations between patients who converted to thoracotomy and the MIE patients (P<0.05). The proportion of multiple and upper thoracic cancer in patients who converted to thoracotomy was higher than that in the MIE patients, while the proportion of lower thoracic cancer was lower than that in the MIE patients. The perioperative mortality of the thoracotomy patients was not significantly different from that of the MIE patients (P=1.000). Conclusion     In MIE, advanced-stage tumor, anesthesia-related factors,extensive thoracic adhesions, and accidental injury of important structures are the main causes of conversion to thoracotomy. The rate varies at different tumor locations. Intraoperative conversion to thoracotomy does not affect the perioperative mortality of MIE.

ABSTRACT

BACKGROUND@#Existing evidence suggests that fruit consumption is a significant influencing factor for chronic obstructive pulmonary disease (COPD), but this is unclear in the Chinese population. We examined the association of fresh fruit consumption with the risk of COPD-related hospitalization and death in a nationwide, population-based prospective cohort from China.@*METHODS@#Between 2004 and 2008, the China Kadoorie Biobank recruited >0.5 million adults aged 30 to 79 years from ten diverse regions across China. After excluding individuals diagnosed with major chronic diseases and prevalent COPD, the prospective analysis included 421,428 participants. Cox regression was used to calculate the hazard ratios (HRs) for the association between fresh fruit consumption and risk of COPD-related hospitalization and death, with adjustment for established and potential confounders.@*RESULTS@#During a mean follow-up of 10.9 years, 11,292 COPD hospitalization events and deaths were documented, with an overall incidence rate of 2.47/1000 person-years. Participants who consumed fresh fruit daily had a 22% lower risk of COPD-related hospitalization and death compared with non-consumers (HR = 0.78, 95% confidence interval [CI]: 0.71-0.87). The inverse association between fresh fruit consumption and COPD-related hospitalization and death was stronger among non-current smokers and participants with normal body mass index (BMI) (18.5 kg/m 2 ≤ BMI < 24.0 kg/m 2 ); the corresponding HRs for daily fresh fruit consumption were 0.78 (95% CI: 0.68-0.89) and 0.69 (95% CI: 0.59-0.79) compared with their counterparts, respectively.@*CONCLUSIONS@#High-frequency fruit consumption was associated with a lower risk of COPD in Chinese adults. Increasing fruit consumption, together with cigarette cessation and weight control, should be considered in the prevention and management of COPD.

ABSTRACT

@#Objective    To investigate the best anatomical classification, surgical timing, procedure and clinical outcomes of congenital vascular ring. Methods    The clinical data of 58 patients who underwent congenital vascular ring surgery in Pediatric Surgery Center, Fuwai Hospital between 2014 and 2019 were retrospectively analyzed. There were 32 (55.2%) males and 26 (44.8%) females with a median age of 16.5 (2-73) months. Preoperative symptoms, imaging examinations, anatomical classifications, surgical procedures and postoperative recovery were assessed. Results    There were 20 (34.5%) patients of double aortic arch, 22 (37.9%) patients of right aortic arch with left arterial duct or ligament, 15 (25.9%) patients of left aortic arch with aberrant right subclavian artery, and 1 (1.7%) patient of circumflex aorta with cervical aorta arch. The median ventilator supporting time was 6.0 (0-648) h, and the median hospital stay time was 14.5 (7-104) d. One patient with coarctation of aorta died of severe pulmonary infection during perioperative period, and the others survived without symptoms and reoperation after discharge. The median follow-up time was 7.0 (1-62) months. Conclusion    For children with unexplained dyspnea and dysphagia, or with right aortic arch, preoperative imaging examinations such as computed tomography or magnetic resonance imaging are required to confirm the diagnosis of vascular ring. Surgical correction of congenital vascular ring is safe and reliable, and can effectively relieve symptoms. The mortality rate and reoperation rate are low, and the follow-up results are satisfactory.

ABSTRACT

Objective@#To examine the association of BMI with major chronic diseases morbidity and all-cause mortality in Chinese adults.@*Methods@#This study is based on China Kadoorie Biobank. Anthropometric indexes were objectively measured at the baseline survey during 2004-2008. After excluding participants with heart disease, stroke, cancer, COPD and diabetes, 428 113 participants aged 30 to 79 years were included in the analysis. Cox regression models were used to investigate the associations of BMI and waist circumference with incidence of major chronic diseases (including cardiovascular disease, cancer, COPD, and type 2 diabetes) and all-cause mortality.@*Results@#Over an average of 10 years, 131 454 participants developed any one of major chronic diseases. A total of 26 892 all-cause deaths were reported. The risk of major chronic diseases increased with BMI. Compared with normal BMI (18.5-24.0 kg/m2), the HR (95%CI) of overweight (BMI 24.0-28.0 kg/m2) and obesity (BMI≥28.0 kg/m2) were 1.26 (95%CI: 1.24-1.27) and 1.59 (95%CI: 1.57-1.62) respectively. Underweight and obesity were both associated with risk of all-cause mortality. Waist circumference was positively associated with risk of major chronic diseases and all-cause mortality. According to recommended cut-off points of BMI and waist circumference for Chinese adults, maintaining a healthy body weight would prevent 12% incident cases of major chronic diseases.@*Conclusion@#General and central obesity were risk factors for major chronic disease among Chinese adults.

ABSTRACT

Objective To investigate gender specific differences in the association between stressful life events (SLEs) and depression in Chinese adults aged 30-79 years. Methods In the baseline survey during 2004-2008, the China Kadoorie Biobank (CKB) recruited 512891 men and women aged 30-79 years from 10 areas of China. Detailed information on SLEs, including demographic and socio-economic status, smoking, alcohol drinking and history of chronic disease, as well as depression symptoms and major depressive episodes (MDEs) in preceding 12 months, was collected by using standardized questionnaire. Multinomial logistic regression model was employed to estimate the relative risk ratio (RRR) and 95%CI of SLEs (3 categories, 10 items) on depression and the dose-response relationship between the number of SLEs experienced and depression. The interactions between gender and SLEs on depression were examined with likelihood ratio test. Results Among the 512891 participants, 35085 (6.8%) reported family-related events, 5972 (1.2%) reported finance-related events, and 4453 (0.9%) reported other stressful life events. Females had a higher occurrence of family-related events, while males had a higher occurrence of finance-related and other events (all P-value <0.001). After adjusted for potential confounders, SLEs were significantly associated with MDEs (RRR=11.99, 95%CI: 10.49-13.71 for males; RRR=14.15, 95%CI: 12.97-15.43 for females), and with depressive symptoms (RRR=7.43, 95%CI:6.94-7.95 for males;RRR=8.30, 95%CI: 7.91-8.72 for females). And the associations were stronger in females than in males (P for interaction=0.049). In the three categories of SLEs, family-related events showed stronger association in female (P for interaction<0.001), while no gender specific differences were observed for the other two categories (all P-value>0.05). Furthermore, the effect of the number of SLEs experienced increased in a dose-response manner on depressive symptoms and MDEs for both genders, but no gender specific differences were found. Conclusions The gender modifies the association between stressful life events and depression in Chinese adults, and women experienced family-related events have a greater risk of depression. The more the stressful events experienced, the more likely to have depression.
