ObjectiveTo evaluate the predictive value of the geriatric nutritional risk index (GNRI) for postoperative overall and severe complications after pancreaticoduodenectomy (PD) in the elderly patients with pancreatic cancer. MethodsThe clinical data of the elderly (65 years old or more) patients with pancreatic cancer underwent PD were retrospectively collected, who were admitted to the Fifth Affiliated Hospital of Xinjiang Medical University from January 2017 to October 2021. The incidences of postoperative overall and severe complications (Clavien-Dindo grade Ⅲ–Ⅴ was defined as severe complications) were summarized. The univariate and multivariate logistic regression models were used to analyze whether GNRI was a risk factor for overall and severe complications after PD. The area under the receiver operating characteristic curve (AUC) was used to evaluate the ability of GNRI to distinguish whether overall or severe complications occurred after PD and to confirm the optimal threshold. Then the patients were assigned into a high nutritional risk group (greater than the optimal threshold) and low nutritional risk group (the optimal threshold or less) based on this. Simultaneously, the clinical outcomes of the two groups were compared. ResultsIn this study, 190 elderly patients with pancreatic cancer were enrolled, 95(50.0%) of whom developed complications, including 28(29.5%) cases of serious complications. The results of multivariate logistic regression model analysis showed that the decreased GNRI was a risk factor for the occurrence of overall and severe complications after PD for the elderly patients [OR(95%CI)=0.361(0.154, 0.848), P=0.019; OR(95%CI)=0.906(0.834, 0.983), P=0.018]. The AUC of GNRI for assessing the occurrence of overall and severe complications was 0.765 and 0.715, respectively, with the optimal critical values of 98 and 96, respectively. Compared with the low nutritional risk group, the high nutritional risk group had higher postoperative total hospitalization costs (Z=–2.37, P=0.019), higher occurrences of overall complications (χ2=44.61, P<0.001) and severe complications (χ2=29.39, P＜0.001). ConclusionsIn elderly patients with pancreatic cancer underwent PD, incidence of serious complications is not lower. GNRI has a good discriminative value in terms of postoperative overall and severe complications. When preoperative GNRI is 98 or less and GNRI is 96 or less, patients should be given early preoperative nutritional support treatment in time.
Objective
To explore risk factors of lymph node metastasis (LNM) in T1 rectal cancer.
Methods
The retrospective case-control study was conducted. The clinicopathologic data of 247 patients with T1 rectal cancer underwent radical resection were analyzed in the pathological database of the West China Hospital from January 2000 to December 2016, including the tumor size (maximum diameter), gross type, differentiation degree, histological type, lymph vascular infiltration, perineural infiltration, and carcinoma nodule. The univariate analysis and multivariate analysis were done using the Chi-square test and logistic regression model, respectively.
Results
The rate of LNM in the patients with T1 rectal cancer was 8.50% (21/247). No lymph metastasis was found in the well differentiated T1 rectal cancer. The results of the univariate analysis showed that the differentiation degree, histological type, and carcinoma nodule were related to the LNM in the T1 rectal cancer (P<0.050). The results of the multivariate analysis revealed that the poor differentiation, mucinous adenocarcinoma, signet-ring cell carcinoma, and carcinoma nodule were the independent risk factors of the LNM in the T1 rectal cancer (OR=9.75, P=0.006; OR=5.98, P=0.042; OR=8.33, P=0.017; OR=10.87, P=0.026).
Conclusion
In this large population dataset, poor differentiation, mucinous adenocarcinoma, signet-ring cell carcinoma, and carcinoma nodule are risk factors of LNM in T1 rectal cancer.
Objective To systematically evaluate the risk factors and population attributable risk of children leukemia in China, so as to provide references for policy-making. Methods The case-control studies about risk factors of children leukemia in China were searched in PubMed, CNKI, CBM, VIP and WanFang Data from inception to December 2011. According to the inclusion and exclusion criteria, two reviewers independently screened articles, extracted data, and evaluated the quality of the included studies. Then Meta-analysis was performed using STATA 11 and Excel 2003. The pooled odds ratio (OR) and 95% confidence interval (95%CI) of each risk factor were calculated, and the population attributable risk percent (PARP) based on the exposure rate of the risk factors was computed, and published bias was estimated according to the fail-safe number. Results A total of 15 case-control studies were included. The first 5 risk factors related to children leukemia were: dwelling environmental pollution (OR=2.782, 95%CI 2.268 to 3.413), house decoration (OR=2.525, 95%CI 1.736 to 3.673), maternal exposure to chemical hazards (OR=2.428, 95%CI 1.976 to 2.985), family history of tumor (OR=2.212, 95%CI 1.677 to 2.919), and child exposure to electromagnetic field around dwelling (OR=2.144, 95%CI 1.761 to 2.610). Factors with higher PARP were influenza history (37.56%), house decoration history (32.95%), X-ray exposure history (20.47%), and chemical hazards exposure history (17.37%). The fail-safe number showed the results were generally reliable. Conclusion In order to prevent and control children leukemia, positive and effective measures should be taken in the following aspects: strengthening child care, avoiding unnecessary X-ray exposure, and providing good living environment.
ObjectiveTo explore the influence of nursing interruption event intervention on the incidence of nursing risk events.
MethodsIn January 2012, we carried out intervention on nursing interruption events. And general situation questionnaire was used on December 30th, 2011 (control group) and December 30th, 2012 (intervention group) respectively to investigate 190 clinical nurses.
ResultsThe occurrence of the interruption events was positively correlated with the incidence of nursing risk events. Effective intervention significantly reduced the incidence of risk events (P<0.05).
ConclusionEffective prevention of adverse outcomes caused by interruption events reduces the risk of nursing, improves the quality of care, and ensures the safety of the patient.
ObjectiveThis study aims to compare different references for the fetal risk of drugs used in pregnancy to provide evidence for the safety of drug use in pregnancy.MethodsFour drug databases, including Lexicomp, Micromedex, TERIS, and Reprotox, as well as two books of drugs in pregnancy edited by Briggs and Schaefer, were searched. Descriptive analysis was performed regarding the definition of pregnancy recommendations and the specific content of medication.ResultsThe six references employed slightly different approaches to drugs in pregnancy, however, all of them included summaries of the risk in pregnancy, data of crossing the placenta, and human and animal data. The databases of Micromedex, TERIS, and a book edited by Briggs had their risk classification systems for drug use during pregnancy. For specific drugs, the summary of different information in pregnancy was different, the amount and content of listed evidence varied, and there was no evaluation of the quality and relevance of evidence among the references.ConclusionsThere is no consensus on the risk assessment of drugs in pregnancy. Risk classification systems for drugs in pregnancy are still an important method for determining the fetal risk of drugs. The existing references merely list studies of drugs in pregnancy, without comprehensive quality assessment. A methodological study of assessment of the risk of drugs in pregnancy is required.
Acute kidney injury (AKI) is a complication with high morbidity and mortality after cardiac surgery. In order to predict the incidence of AKI after cardiac surgery, many risk prediction models have been established worldwide. We made a detailed introduction to the composing features, clinical application and predictive capability of 14 commonly used models. Among the 14 risk prediction models, age, congestive heart failure, hypertension, left ventricular ejection fraction, diabetes, cardiac valve surgery, coronary artery bypass grafting (CABG) combined with cardiac valve surgery, emergency surgery, preoperative creatinine, preoperative estimated glomerular filtration rate (eGFR), preoperative New York Heart Association (NYHA) score>Ⅱ, previous cardiac surgery, cadiopulmonary bypass (CPB) time and low cardiac output syndrome (LCOS) are included in many risks prediction models (>3 times). In comparison to Mehta and SRI models, Cleveland risk prediction model shows the best discrimination for the prediction of renal replacement therapy (RRT)-AKI and AKI in the European. However, in Chinese population, the predictive ability of the above three risk prediction models for RRT-AKI and AKI is poor.
Breast cancer, the most common malignancy in the world, also causes the most death cases of women among malignancies. Breast cancer risk reduction guidelines (version 2023) was updated by National Comprehensive Cancer Network (NCCN). Based on high-level evidences from evidence-based medicine and the latest research progress, the guidelines provided standardized guidance for breast cancer risk assessment and risk reduction strategies for individuals without a history of invasive breast cancer or ductal carcinoma in situ, which has attracted widespread attention from clinicians worldwide. Breast cancer is also the most common malignancy in Chinese women, and the number of newly diagnosed breast cancer cases each year in China ranks first in the world due to the large population, so the breast cancer prevention has become a major public health challenge in China. Aimed to provide reference for breast cancer prevention in China, this article interpreted the guidelines (the new version) based on the characteristics of breast structure in Asian women and the epidemiological characteristics of breast cancer in China.
Post operational recovery from cardiac surgery can be affected by many factors, including preoperative, intraoperative, and postoperative factors. Prolonged mechanical ventilation (PMV) , one of the major complications, has been widely accepted as a measure to evaluate the performance and outcomes of cardiac surgeries. Great progress has been made in the studies of risk factors contributing to PMV following cardiac surgeries in recent years. However, no clear and effective measures and approaches are available yet to prevent PMV. In this review, the authors try to summarize the risk factors that are associated with PMV throughout the perioperative period of cardiac surgery, as well as possible interventions when applicable.
Objective
To explore the status of nutrition risk and its relative factors in patients of department of gastrointestinal surgery, and to observe the effectiveness of nutrition support on post-operative recovery of patients with gastric cancer.
Methods
A total of 1 048 cases of in-patients in Department of Gastrointestinal Surgery of Jinan Central Hospital Affiliated Shandong University from January 2015 to January 2016 were collected prospectively, and then screened the nutrition risk of these patients by nutritional risk screening 2002 (NRS-2002) and evaluated the actual malnutrition situation when they left hospital. Then collected 52 gastric cancer patients whose NRS-2002 score ≥3, and divided them to control group and experimental group randomly. The patients of experimental group received extra standard medical nutrition support while the patients of control group did not. Compared the nutritional indexes as well as some postoperative recovery indexes, such as the postoperative exhaust time, postoperative defecation time, infusion stop time, length of hospital stay, and incidence of complications.
Results
① Nutritional risk. Among the 1 048 cases, 230 cases (21.9%) had nutritional risk while 118 cases (11.3%) developed to malnutrition. Age and degree of cancer were all related with nutritional risk (P<0.05) while gender was irrelevant (P>0.05). Patients with age ≥60 years, advanced gastric cancer, and colorectal cancer in Ⅲ+Ⅳ staging, had higher rates of nutritional risk than patients with age <60 years, early gastric cancer, and colorectal cancer inⅠ+Ⅱstaging. Results of actual malnutrition was in good accordance with the screening result of NRS-2002 (κ=0.57). ② Influence of nutritional support on gastric cancer patients. Compared with control group, there was an improvement in albumin, pre-albumin, and weight of experimental group and the distinction had statistical significance (P<0.05). The distinction of postoperative exhaust time and incidence of complication between the two groups were not statistically significant (P>0.05), but postoperative defecation time, infusion stop time, and the length of hospital stay of the experimental group were shorter than those of the control group with statistical significance (P<0.05).
Conclusions
The problem of malnutrition exists generally in the in-patients of department of gastrointestinal surgery. Applying the instrument of nutritional risk assessment to assess the risk as early as possible and giving appropriate nutrition support therapy positively, will make favorable influence to the prognosis of gastric cancer patients.
