BACKGROUND: Management of gastric leak after sleeve gastrectomy (SG) is challenging due to its unpredictable outcomes. We aimed to summarize the characteristics of SG leaks and analyze interventions and corresponding outcomes in a real-world setting. METHODS: To retrospectively review of 15,721 SG procedures from 2010 to 2020 based on a national registry. A cumulative sum analysis was used to identify a fitting curve of gastric leak rate. The Kaplan-Meier method and log-rank tests were performed to calculate and compare the probabilities of relevant outcomes. The logistic regression analysis was conducted to determine the predictors of acute leaks. RESULTS: A total of 78 cases of SG leaks were collected with an incidence of 0.5% (78/15,721) from this registry (6 patients who had the primary SG in non-participating centers). After accumulating 260 cases in a bariatric surgery center, the leak rate decreased to a stably low value of under 1.17%. The significant differences presented in sex, waist circumference, and the proportion of hypoproteinemia and type 2 diabetes at baseline between patients with SG leak and the whole registry population ( P = 0.005, = 0.026, <0.001, and = 0.001, respectively). Moreover, 83.1% (59/71) of the leakage was near the esophagogastric junction region. Leakage healed in 64 (88.9%, 64/72) patients. The median healing time of acute and non-acute leaks was 5.93 months and 8.12 months, respectively. Acute leak (38/72, 52.8%) was the predominant type with a cumulative reoperation rate >50%, whereas the cumulative healing probability in the patients who required surgical treatment was significantly lower than those requring non-surgical treatment ( P = 0.013). Precise dissection in the His angle area was independently associated with a lower acute leak rate, whereas preservation ≥2 cm distance from the His angle area was an independent risk factor. CONCLUSIONS Male sex, elevated waist circumference, hypoproteinaemia, and type 2 diabetes are risk factors of gastric leaks after SG. Optimizing surgical techniques, including precise dissection of His angle area and preservation of smaller gastric fundus, should be suggested to prevent acute leaks.

Objective:To evaluate the clinical effectiveness of the standardized peripherally inserted central catheter (PICC) implantation procedure in the management of parenteral nutrition infusion routes.Methods:Patients were enrolled from January 2018 to January 2020 and were divided into the study and control groups, receiving standard operating procedures of PICC or insertion through below elbow with or without ultrasonic guidance. The differences in the success rate of PICC insertion, catheter indwelling time, incidence rate of complications, and patient satisfaction were compared.Results:A total of 943 subjects were included. The study group and the control group were comparable in terms of baseline characteristics such as disease type, body mass index and prevalence of nutritional risk. The overall success rate was 100% in both groups. The first-attempt success rate in the study group was higher compared with the control group (92.6% vs 72.2%, χ 2 = 66.229, P < 0.001), and the catheter indwelling time was longer ([25.4 ± 2.3] d vs [21.6 ± 3.1] d, t = 21.271, P < 0.001). The incidence rate of short-term complications in the study group was significantly lower than that in the control group (3.50% vs 11.52%, χ 2 = 21.490, P <0.001), while there was no significant difference in the incidence rate of long-term complications between the two groups (6.78% vs 8.85%, χ 2 = 1.388, P = 0.239). Conclusion:Establishing and implementing the standardized operating procedure of PICC is an effective method to improve the management of parenteral nutrition infusion routes.

Objective:To analyze the medical knowledge map of lifestyle medicine based on Web of Science database.Methods:“Lifestyle medicine” “lifestyle intervention” “lifestyle medicine strategy” and “lifestyle factor” were used as Mesh terms to search the core collections of Web of Science database. The time span was from January 1st, 2000 to December 31st, 2021. The statistical function of Web of Science database was used for bibliometric analysis, and VOS Viewer software was used for co-occurrence analysis of authors, countries, institutions, keywords, and cited literature, then the visual knowledge maps were drawn.Results:A total of 5 717 articles were included, and the number of published articles from 2000 to 2021 showed an increasing trend. The top 10 authors were from the United States (nine authors) and Finland (one author); high producing countries included the United States (2 882 papers), the United Kingdom (1 254 papers) and Australia (781 papers), and China ranked sixth (499 papers). The most productive institutions were the Union of European Research Universities (946 articles), Harvard University (677 articles), University of California (313 articles), etc. The papers are mainly published in Diabetes, Circulation, BMC Public Health, Obesity, PLoS One, Med Sci Sports Exerc, etc. Five clusters were obtained by co-occurrence of key words, which were “health status” “lifestyle intervention” “lifestyle risk factors” “exercise and weight” and “chronic disease research”. The national cooperation network involves 67 countries. Conclusions:Recently, the research on lifestyle medicine shows a rapid growth trend. The current research interests include behavioral sciences, psychology, nutrition, endocrinology and metabolism, healthcare services, internal medicine, public health, pathology, cardiovascular medicine and geriatrics. Research hotspots include chronic disease and disease burden, whole life-cycle health, nutrition and exercise intervention and behavior change.

Objective To evaluate the correlation between microvascular invasion(MVI) and prognosis in patients with hepatocellular carcinoma (HCC),and to analyse the influencing factors of MVI in patients with HCC.Methods Total of 81 patients with hepatocellular carcinoma treated in Beijing Hospital from January 2014 to December 2016 were retrospectively studied.There were 65 males and 16 females.The mean age was 59.6± 12.7 years,and the age ranged from 21 to 87 years old.Pathological examination showed presence of MVI in 35 patients.Results Total of seventy-six patients with hepatocellular carcinoma were followed-up.The 1-,2-,3-and 4-year overall survival rates in the 35 patients with microvascular invasion of hepatocellular carcinoma were 78.6％,55.4％,38.3％,and 32.2％,respectively.The 1-,2-,3-,and 4-year overall survival rates of the 41 patients without microvascular invasion were 93.4％,76.5％,68.2％ and 68.2％,respectively.The difference was significant (P＜0.05).Cox multivariate regression analysis showed that microvascular invasion was an independent risk factor of overall survival after surgery (HR=3.071,95％ CI:1.239～7.610,P＜0.05).Sub-group analysis was done on patients with microvascular invasion based on pathological results which included the number of MVI lesions,the call number in the MVI lesion,the distance of the MVI to the primary liver cancer,and the gradings of MVI.There were no significant differences in the overall survival outcomes (P＞0.05).Multivariate logistic regression analysis showed the maximum diameter of tumor ＞ 5 cm (OR =6.340,95％ CI:2.000 ～ 20.096),preoperative total bilirubin (TBil) ＞ 17 μmol/L (OR =5.067,95％CI:1.386 ～ 18.525),and preoperative alpha-fetoprotein (AFP) ＞400 μg/L (OR =6.042,95％ CI:1.435 ～ 25.444) were independent risk factors of microvascular invasion (P＜ 0.05).Conclusion Hepatocellular carcinoma patients with microvascular invasion had poor prognosis.Preoperative AFP,preoperative TBil,and diameter of tumor were independent risk factors of microvascular invasion in patients with hepatocellular carcinoma.

Objective: To explore the relationship between serum levels of immunoglobulin E (IgE) and calciifc aortic valve disease (CAVD) in relevant patients.
Methods: A total of 394 patients were enrolled in our study. Based on echocardiography presentation, the patients were divided into 2 groups: CAVD group,n=169 and Non-CAVD group,n=225. Serum levels of IgE were examined by chemiluminescence method. The IgE levels were compared between 2 groups and the relationship between serum IgE level and CAVD was analyzed.
Results: Serum levels of IgE in CAVD group was significantly higher than Non-CAVD group 113.30 IU/ml vs 63.76 IU/ml (P<0.05); multivariate logistic regression analysis conifrmed above difference (P<0.05) and it also indicated that the alteration of surum IgE level is obviously related to CAVD occurrence.
Conclusion: Serum IgE level is obviously increased in CAVD patients. IgE is an independent biochemical indicator of CAVD, it may play the important role in CAVD pathogenesis.

Objective To summarize the clinical outcomes after the optimization of nutrition support in elderly patients after hepatic carcinoma surgery.Methods The clinical data of 52 elderly patients with hepatic carcinoma in Beijing Hospital were collected and analyzed from 2007 to 2009(research group).Nutritional Risk Screening(NRS)2002 was applied for the nutrition risk screening at admission.NRS 2002 score≥3 was regarded as at nutritional risk.Enteral nutrition(EN)or EN combined with parentoral nutrition(EN+PN)supports were provided during the peri-operative stage.The control group included 30 patients from 2005-2007 under the same conditions with rescareh group but only received PN supports pest-operatively.Nutritional parameters,complications,lengh of hospital stay,and healthcare expenditures were analyzed.Results Body weight and plasma albumin were no significantly different in two groups(P>0.05)by the 7th post-operative day.The incidence of infection-relatod complications and length of hospital stay were significantly lower in research group than in control group (P<0.05).Conclusions Nutrition risk screening should be performed for the elderly patients with hepatic carcinoma after admission.Optimization of peri-operative nutrition support can reduce complications and improve the clinical outcomes.
