ABSTRACT
Objective:To explore the accuracy of intelligent calculation (IC) method for risk assessment of hospitalization for patients, aiming to build a more advantageous risk assessment system.Methods:The "Search Engine" program was developed based on hospital information system (HIS) of the Fifth Center Hospital in Tianjin, which automatically captured patient information and generated nutritional risk screening 2002 (NRS 2002) score, Caprini thrombosis risk assessment model and Padua thrombosis risk assessment model for venous thromboembolism (VTE), the CHA 2DS 2-VASc for predicting stroke risk stratification in atrial fibrillation and the HAS-BLED for predicting bleeding risk in anticoagulated patients with atrial fibrillation. A randomized controlled trial was conducted. According to the applicable conditions of each risk assessment, 100 risk scores from "Search Engine" program belonged to each risk assessment were randomly selected, defined as the IC group. Manual scoring with the data of the same case at the same time, defined as the traditional calculation (TC) group, compared the consistency of the scores and the difference in time-consuming between the two groups. Results:The Bland-Altman plots showed that the 95% limits of agreement (95% LoA) of NRS 2002 score, Caprini score, Padua score, CHA 2DS 2-VASc score and HAS-BLED score was -0.46 to 0.41, -0.49 to 0.52, -0.50 to 0.41, -0.67 to 0.60, -0.44 to 0.43, respectively, all P > 0.05. In this study, the Bland-Altman plot showed that 95%, 96%, 97%, 97%, 95% plots fell within the 95% LoA in NRS 2002 score, Caprini score, Padua score, wwCHA 2DS 2-VASc score and HAS-BLED score by the two methods, respectively. The all plots of 95% LoA were within the clinically acceptable range (-0.5 to 0.5 scores). The time-consuming of NRS 2002 score, Caprini score, Padua score, CHA 2DS 2-VASc score and HAS-BLED score in IC group were significantly shorter than those in TC group [0.72 (0.71, 0.73) seconds vs. 361.02 (322.41, 361.02) seconds, 0.72 (0.72, 0.73) seconds vs. 196.68 (179.99, 291.20) seconds, 0.72 (0.72, 0.73) seconds vs. 105.75 (92.32, 114.70) seconds, 0.72 (0.71, 0.72) seconds vs. 72.66 (56.24, 84.20) seconds, 0.72 (0.71, 0.72) seconds vs. 51.30 (38.88, 57.15) seconds, respectively, all P < 0.001]. Conclusion:For the above five risk assessments, the TC method and IC method has good consistency in scores, and the IC method is faster, which has good application prospect for clinical application.
ABSTRACT
Objective:To explore the characteristics of the changes in risk score for intensive care unit (ICU) patients during hospitalization by the intelligent calculation method, and to provide evidence for the risk prevention.Methods:In this retrospective study, ICU patients of the Fifth Central Hospital in Tianjin from November 3, 2021 to March 28, 2022 were enrolled and divided into ≥ 14 days group, 10-13 days group, 7-9 days group, and 3-6 days group according to the ICU length of stay. Risk scores assessed by the intelligent calculation method of the ICU patients were collected, including nutritional risk screening 2002 (NRS 2002), Caprini score and Padua score. NRS 2002 score for all patients, Caprini score for surgical patients and Padua score for internal medicine patients were selected. Trends in change of each score were compared between patients admitted to ICU 1, 3, 7 (if necessary), 10 (if necessary), and 14 days (if necessary).Results:A total of 138 patients were involved, including 79 males and 59 females, with an average age of (61.71±18.86) years and an average hospital stay of [6.00 (4.00, 9.25)] days. ① in the group with ICU length of stay ≥ 14 days (21 cases): there was no significant change in the NRS 2002 scores of the patients within 10 days, but the NRS 2002 score was significantly decreased in 14 days as compared with 1 day [3.00 (2.50, 3.50) vs. 4.00 (3.00, 5.00), P < 0.05]; both Caprini and Padua score were increased with prolonged hospital stay and compared with 1 day, the scores at the other time points were significantly increased, especially at 14 days [Caprini score: 5.00 (3.25, 7.00) vs. 2.50 (1.25, 5.50), Padua score: 6.00 (6.00, 7.00) vs. 3.00 (1.00, 3.00), both P < 0.05].② in the group with ICU length of stay from 10-13 days (15 cases): with the prolonged hospital stay, there was no significant change in NRS 2002 score, but both Caprini and Padua score were increased at 3, 7, 10 days, especially at 10 days [Caprini score: 3.00 (2.00, 4.75) vs. 2.00 (0.25, 2.75), Padua score: 5.00 (3.50, 6.00) vs. 2.00 (0.50, 4.00), both P < 0.05].③ in the group with ICU length of stay from 7-9 days (23 cases): compared with 1 day, the NRS 2002 score at 3 days and7 days were decreased, but the Caprini and Padua score were increased, especially at 7 days [NRS 2002 score: 2.00 (1.00, 4.00) vs. 2.00 (2.00, 4.00), Caprini score: 3.00 (2.00, 5.50) vs. 2.00 (0.25, 3.00), Padua score: 5.00 (4.00, 6.00) vs. 2.00 (0, 2.00), all P < 0.05]. ④ in the group with ICU length of stay from 3-6 days (79 cases): compared with 1 day, the NRS 2002 score at 3 days was decreased [NRS 2002 score: 2.00 (1.00, 3.00) vs. 2.00 (1.00, 3.00), P < 0.05], Caprini and Padua score were significantly increased [Caprini score: 3.00 (2.00, 4.00) vs. 2.00 (1.00, 3.00), Padua score: 5.00 (4.00, 5.00) vs. 2.00 (1.00, 3.00), both P < 0.05]. Conclusion:Based on dynamic assessment of intelligent calculation methods, the risk of thrombosis in ICU patients increased with hospital length of stay, and the nutritional risk was generally flat or reducing in different hospitalization periods.
ABSTRACT
Objective@#The present study aimed to examine the mediated moderation effect underlying the association between parental psychological aggression and phubbing, as well as the mediating role of anxiety and moderating role of sex and grade. @*Methods@#Based on a cross-sectional study, a total of 758 Chinese junior high school students had completed measures on socio-demographic characteristics, parental psychological aggression, anxiety and phubbing. Structural equation modeling was adopted to examine the mediating effect of anxiety on the association between parental psychological aggression and phubbing. Multigroup analyses were conducted to explore whether the path coefficients differed by sex and grade. @*Results@#Mediation analysis indicated that anxiety could mediate the association between parental psychological aggression and phubbing. The indirect effect of parental psychological aggression on phubbing via anxiety was 0.12. Multigroup analyses revealed that the higher mediation effect of anxiety was more likely to be reported by boys and students from grade eight. @*Conclusion@#Findings of the present study may inform prevention and intervention programs for phubbing in adolescents exposed to parental psychological aggression, by decreasing the anxiety and adopting selective strategies for different sex and grade groups.
ABSTRACT
Objective:To evaluate the day-surgery unit-based training of laparoscopic cholecystectomy (LC).Methods:Perioperative data of 438 patients (187 males and 251 females) with a median age of 54 (aged 17 to 91) years undergoing LC during January 2019 to April 2021 in the day-surgery unit of Chinese PLA General Hospital were retrospectively collected and subdivided according to the training methods of surgeons [Group A( n=260): conventional training vs. Group B ( n=178): protocoled stepwise training]. The protocoled stepwise training consists of the rotation in open biliary surgery unit, the stimulator-based laparoscopic training, and the stepwise procedural tutoring. The conventional training features the traditional surgical practice following senior surgeons. The technical data involving operation time, blood loss, the percentages of intraoperative decision-making by senior surgeons and the handing-over of procedure to senior surgeons, etc. were statistically analyzed. Results:The operation time was shortened in Group B [(55±30) min vs. (61±33) min], with significantly decreased percentages of intraoperative decision-making by senior surgeons [7.9% (14/178)vs. 16.9%(44/260), P<0.05] and the handing-over of procedure to senior surgeons [3.4%(6/178) vs. 11.2%(29/260), P<0.05]. Conclusion:Based on the protocoled stepwise training and the consecutive, high-volumed and standardized procedures, the laparoscopic technical proficiency and competency of the trainee surgeons have been improved.
ABSTRACT
Objective:To investigate the value of neutrophil-to-lymphocyte ratio (NLR) in the diagnosis and prognosis evaluation of primary hepatocellular carcinoma.Methods:The clinical data of 100 patients pathologically diagnosed as primary liver cancer who were admitted to the First Medical Center of Chinese PLA General Hospital from January 2013 to December 2015 were retrospectively analyzed. Serum alpha fetoprotein (AFP), a conventional marker for hepatocellular carcinoma diagnosis was used as the control. The fourfold table diagnostic test was applied to analyze the sensitivity and specificity of serum NLR in the diagnosis of hepatocellular carcinoma, and the correlation with the degree of tumor differentiation was also analyzed.Results:The proportion of patients with high NLR (≥1.70) [56% (56/100)] was higher than the proportion of patients with positive AFP [44% (44/100)] in all 100 hepatocellular carcinoma patients, but the difference was not statistically significant ( χ2 = 2.88, P = 0.08). Among AFP-positive patients, the median survival time of patients with low and high NLR was 59 and 48 months, respectively, and the difference was statistically significant ( χ2 = 3.91, P = 0.048), and high NLR was an independent risk factor affecting the prognosis of hepatocellular carcinoma patients ( HR = 1.232, 95% CI 1.055-1.438, P = 0.008). Conclusions:The detection of NLR combined with AFP can improve the diagnostic rate of hepatocellular carcinoma before surgery. High NLR is an independent risk factor affecting the prognosis of patients with primary hepatocellular carcinoma.
ABSTRACT
Objective:To summarize clinical experience in the management of Abernethy malformation combined with focal nodular hyperplasia (FNH).Methods:Three patients with Abernethy malformation combined with FNH who were managed in the Department of Hepatobiliary Surgery, the First Medical Center of Chinese PLA General Hospital from January 2010 to December 2018 entered into this study. There were one male aged 35 years and two females aged 21 years and three years and nine months, respectively. Patients underwent digital subtraction angiography (DSA) with balloon dilation, shunt vasulature ligation, portal vein (PV) pressure measurement and other investigations were performed to study the changes of PV pressure before and after treatment.Results:DSA indicated that the congenital portal shunt of the patients was Abernethy deformity Ⅱ and Ⅰb, respectively, and with combined FNH diagnosed preoperatively. One patient was admitted to hospital for partial hepatectomy 5 years ago for the treatment of FNH, which presented with recurrent abdominal pain. The PV pressure increased from 8.5, 9.0, 20.0 cmH 2O(1 cmH 2O=0.098 kPa) to 15.0, 21.0, 25.0 cmH 2O after portal cavity shunt vasculature/portal vein ligation and splenic artery ligation/portal body shunt ligation, respectively. The PV blood flow into the liver increased, and DSA suggested shunt vessel occlusion. On follow-up, all patients survived well. Conclusion:Ligation or constriction of shunt vessels significantly improved the flow of PV into liver in Abernethy malformation patients with FNH. The treatment benefited long-term survival.

Objective To evaluate three-dimentional (3D) reconstruction technique and methylene blue staining in precise anatomic hepatectomy.Methods The clinical data of 12 patients with hepatocellular carcinoma who were admitted to the Chinese PLA General Hospital from February 2009 to August 2011 were retrospectively analyzed.The 3D reconstruction of the liver tumor and intrahepatic vessels were done based on the computed tomography data and magnetic resonance imaging data.The portal vein supplying the tumor and its anatomic relationship with adjacent vessels were evaluated.Precise anatomic hepatectomy was performed guided by sustained methylene blue staining.Results The accurate rate of 3D model of the portal triad was 12/12.The shape of target segments observed after methylene blue staining was consistent with the results of 3D evaluation.Two patients received hemihepatectomy,3 received lobectomy,5 received monosegmentectomy or subsegmentectomy,2 received multisegmentectomy.The mean tumor diameter,operation time,blood loss,postoperative hospital stay and complication rate were 5.6cm (2.5-16.0 cm),(150±24)minutes,(236±25)ml,(10±3)days and 2/12,respectively.After a median follow-up of 14 months,tumor recurrence was found in 2 patients,and 1 of them died of tumor progression.Conclusions The 3D reconstruction may contribute to precise evaluation of the anatomic relationship between the tumor and its adjacent vessels.The 3D technique combined with sustained methylene blue staining may significantly improve the accuracy of anatomic hepatectomy.
ABSTRACT
Objective To analyse the cost-effectiveness analysis of the focal injection treatment under the guidance of contrast enhanced ultrasound(CEUS) for the severe abdominal parenchymal organs trauma.Methods One hundred and twelve patients with severe abdominal parenchymal organs trauma,including 42 hepatic injuries,52 splenic injuries and 33 renal injuries,were rolled in this study. The cost-effectiveness of this group was compared with that of surgery group. Results Treatment duration of single organ trauma under the guidance of CEUS was 20 - 30 minutes. During the first 72 hours after the focal injection, blood pressure and heart rate were improved ( P ＜0.05). Free intraperitoneal liquid did not increase on immediate US image of post-therapy and then it disappeared gradually. Heart rate returned to normal level after injection treatment ( P ＜0. 001 ). Lengths of stay in hospital was 3 - 11 (5.4 ± 2.4)days, which was not different with 3 - 9(5.1± 1.9) of surgery group( P ＞0.05). Treatment cost was 0.32 - 0.43 (0.36 ±0. 14) ten thousand RMB, which was obviously less than 3. 1 - 4. 2 (3.6 ± 10.8) ten thousand RMB of surgery group ( P ＜ 0.01 ). Conclusions The efficacy of the focal injection treatment of the severe abdominal parenchymal organs trauma under the guidance of CEUS was consistent with that of the operative treatment, but its cost was less. Especially it benefited for reserving organs and less pain.
ABSTRACT
Since the 1980s, indications for resection of hilar cholangiocarcinoma have progressively improved. Operation is superior to any other therapeutic modalities with regard to survival rate and quality of life. Currently, hepatic lobectomy, extended hepatic lobectomy, extrahepatic bile duct resection, regional lymphadenectomy and Roux-en-Y hepatoenteric jejunos-tomy are recommended as the treatment of choice for most patients with hilar cholangiocarcinoma. However, controversy still remains regarding the diagnosis and treatment of hilar cholangiocarcinoma, including the assessment of longitudinal tumor extension, the evaluation of hepatic reserve function, the value of biliary drainage, the indication of portal vein emboliza-tion, the range of hepatic resection, the contribution of com-bined vascular resection, and the effectiveness of liver transplan-tation. This article summarizes these main issues requiring further investigation.
ABSTRACT
Objectives:To observe the role of parenteral nutrition(PN) in the elderly postoperative patients with gastric carcinoma. Methods:Forty cases were randomly divided into two groups. One group received PN after operation as PN group and another group was supported only with the general treatment without PN as control group. Results:①The rate of postoperative complications was 15% (3/20) with no death in PN group, and it was 45%(9/20) with mortality rate of 5%(1/20) in control group. ② Between the two groups, there were very significant differences in nitrogen balance, body weight, creatinine height index(CHI), serum albumin, serum transferrin and blood urea nitrogen(BUN) at the 8th postoperative day( P
