RESUMO
【Objective】 To examine risk factors for acute pancreatitis (AP) in individuals with chronic alcohol consumption habits. 【Methods】 The study incorporated participants from the initial survey (2006-2010) and subsequent follow-ups (2014+) taken from the UK Biobank database, with the observation period ending on November 30, 2022. During this period, 176 individuals were newly diagnosed with AP, while 59,512 remained unaffected. Vital characteristics of the target population, such as their medical histories, surgical experiences and dietary patterns, were collected during the enrolment phase (2006-2010). The Cox proportional hazard model was employed to ascertain whether these characteristics were potent risk factors for AP. Concurrently, a subgroup from the target population with documented drinking behavior was selected. The multivariate Cox proportional hazard model was utilized to analyze the relationship of the established factors, variances in alcohol consumption, and increased alcohol intake (Δ) with the onset of AP, and whether the additional alcohol intake served as a risk factor. 【Results】 Multivariate analysis revealed that consumption quantity of cooked vegetables inversely correlated with AP risk (HR=0.44, 0.39, 0.42 and 0.41 for one, two, three and four+ tablespoons per day, respectively, as compared to non-consumers). Coffee consumption (2-3 cups per day) also reduced AP risk (HR=0.45 for 2 cups/day; HR=0.39 for 3 cups/day as compared to non-coffee drinkers). However, those with biliary disease without cholecystectomy exhibited a marked increase in AP risk (HR=7.82), which reduced albeit remained elevated for those with biliary disease post-cholecystectomy (HR=2.15). Subgroup analysis showed minimal impact of alcohol intake levels on AP incidence. Yet, increased alcohol consumption (Δ of 1 bottle/week) was linked to a heightened AP risk (HR=1.05, 95% CI:1.02-1.09, P<0.05). 【Conclusion】 Among longstanding alcohol consumers, a diet rich in cooked vegetables and moderate coffee consumption offers protective effects against AP. Conversely, biliary disease (particularly without cholecystectomy) and elevated alcohol intake present considerable risk factors for the development of this condition.
RESUMO
Objective:To investigate the effect of levothyroxine withdrawal before radioiodine therapy on blood lipids and renal function in patients with differentiated thyroid carcinoma (DTC) after operation.Methods:From Mar. 2020 to Apr. 2022, 214 patients with differentiated thyroid cancer were enrolled in the General Surgery Department, Linyi Central Hospital, Shandong Province. All patients stopped taking levothyroxine sodium after total thyroidectomy. The thyroid function index, blood lipid index and renal function index were measured and compared before and after drug withdrawal (before operation) and after drug withdrawal (before radioiodine treatment). The patients were divided into groups according to the duration of drug withdrawal (drug withdrawal group for 3 weeks, drug withdrawal group for 4 weeks), and the differences of thyroid function index, blood lipid index, and renal function index among patients with different drug withdrawal time were compared. The measurement data in accordance with normal distribution were compared between groups, and independent sample t-test was performed. Results:The levels of free thyroxin T4 (FT 4) and free triiodothyronine (FT 3) in DTC patients decreased significantly ( t=57.60, 71.74,all P<0.001), and the levels of thyroid-stimulating hormone (TSH) increased significantly ( t=102.15, P<0.001). After drug withdrawal, the serum lipid index [triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), low density lipoprotein (LDL) ] and renal function index [blood urea nitrogen (BUN), serum creatinine (SCR) ] of DTC patients increased significantly ( t=20.17, 42.50, 12.13, 30.73, 16.09, 43.73, all P<0.001). The levels of FT 3 and FT 4 in the 4-week group were significantly lower than those in the 3-week group ( t=7.75 and 10.07, both P<0.001), and TSH was significantly higher than that in the 3-week group ( t=26.46, P<0.001). The levels of TG, LDL, HDL, TC, BUN and Scr in the 4-week group were significantly higher than those in the 3-week group ( t=10.13, 10.29, 8.53, 11.47, 10.54, 8.55, all P<0.001). Correlation analysis showed that the levels of FT 3 and FT 4 in DCT patients were negatively correlated with the levels of TG, LDL, HDL, TC, BUN and Scr ( r=-0.256, -0.189, -0.249, -0.314, -0.352, -0.231, -0.342, -0.259, -0.304, -0.216, -0.391, -0.271, P=0.011, 0.029, 0.007, 0.004, 0.015, 0.036, 0.002, 0.009, 0.019, 0.017, 0.016, 0.003), and the levels of TSH were correlated with TG, LDL, HDL, TC and BUN Scr level was positively correlated ( r=0.257, 0.308, 0.219, 0.311, 0.251, 0.271, P=0.006, 0.013, 0.032, 0.004, 0.006, 0.014) . Conclusion:Stopping levothyroxine sodium before radioactive iodine treatment after DTC can easily lead to dyslipidemia and decreased renal function in patients, and the longer the withdrawal time is, the more obvious the changes of blood lipids and renal function in patients, and the withdrawal time should be shortened in clinical treatment.
RESUMO
Objective:To evaluate the predictive value of neutrophil-to-lymphocyte ratio (NLR) for adult severe tetanus by comparing the NLR in patients with severe and mild tetanus.Methods:A total of 65 adult tetanus patients from the Linyi Central Hospital from January 2009 to December 2020 were enrolled. The patients were divided into two groups including mild group and severe group according to the Ablett classification. The general conditions, laboratory data, and NLR of patients in two group were retrospectively compared using independent samples t test. Multivariate logistic regression analysis was used for the analysis of risk factors for severe tetanus. Spearman correlation method was used for the analysis of the correlation between risk factors and Ablett grades. Receiver operator characteristic (ROC) curve was used for the evaluation of the predictive value. Results:Among the 65 tetanus cases, 34 was in mild group and 31 in severe group. The latency period of patients in severe group was (7.00±3.19) d, which was shorter than that in mild group ((9.18±2.59) d), and the difference was statistically significant ( t=3.03, P=0.004). The NLR of patients in severe group was 4.251±1.936, which was higher than that of mild group (2.533±1.026) , and the difference was statistically significant ( t=4.41, P<0.001). Multivariate logistic regression analysis showed that NLR and latency period were independent risk factors for tetanus severity (odds ratio ( OR)=2.359, 95% confidence interval ( CI) 1.415 to 3.934, P=0.001 and OR=0.748, 95% CI 0.599 to 0.936, P=0.011, respectively). In tetanus patients, the NLR level was positively correlated with Ablett grade ( r=0.644, P<0.001). The ROC curve showed that NLR had good predictive value for adult severe tetanus at a cut-off value of 2.471 (area under the curve (AUC)=0.787), with the sensitivity and specificity of 87.1% and 61.8%, respectively. When combining NLR with latency period (cut-off value of 7.5 d), predictive efficiency was further improved (AUC=0.832) with the sensitivity of 87.1% and specificity of 67.6%( Z=3.43, P<0.001). Conclusions:NLR has a good predictive value for adult severe tetanus, and the predictive efficiency is further improved when combined with latency period.

Objective To investigate the proper selection of methods of hepatic vascular control during(resection) of liver carcinoma.Methods Ninety-foury cases of liver carcinoma underwent hepatectomy using 4 different types of hapatic vascular control in our hospital.The operative time,amount of intraoperative blood loss,transfusion,and postoperative drainage,changes of postoperative liver function and complications were analyzed and compared between the 4 groups.Results Of the 94 cases,38(40.4%) underwent routine Pringle′s maneuver,34(36.2%) had selective hemihepatic vascular exclusion,18(19,1%) without(hepatic) inflow occlasion and 4(4.3%) had total vascular exclusion during hepatectomies.All tumors were entirely removed and operations were performed smoothly.Postoperative complications occurred 24 case-times and 2 patients(2.1%) died.Conclusions The selection of method of hepatic vascular control during(hepatectomy) for massive liver carcinoma should be comprehensively determined,based on the size and location of tumor,preoperative liver function,diffculty of hepatectomy and findings at intraoperative exploration.Proper method manner of hepatic vascular control is crucial for successful operation and uneventful recovery of the(patient).
