AIM: To determine factors related to disease severity, mortality and morbidity in acute pancreatitis.METHODS: One hundred and ninety-nine consecutive patients were admitted with the diagnosis of acute pancreatitis (AP) in a 5-year period (1998-2002). In a prospective design, demographic data, etiology, mean hospital admission time, clinical, radiological, biochemical findings, treatment modalities, mortality and morbidity were recorded. Endocrine insufficiency was investigated with oral glucose tolerance test. The relations between these parameters, scoring systems (Ranson, Imrie and APACHE Ⅱ) and patients' outcome were determined by using invariable tests and the receiver operating characteristics curve.RESULTS: One hundred patients were men and 99 were women; the mean age was 55 years. Biliary pancreatitis was the most common form, followed by idiopathic pancreatitis (53% and 26%, respectively). Sixty-three patients had severe pancreatitis and 136 had mild disease. Respiratory rate 〉 20/min, pulse rate 〉 90min, increased C-reactive protein (CRP), lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) levels, organ necrosis 〉 30% on computed tornography (CT) and leukocytosis were associated with severe disease. The rate of glucose intolerance, morbidity and mortality were 24.1%, 24.8% and 13.6%, respectively. CRP 〉 142 mg/L, BUN 〉 22 mg/dL, LDH 〉 667 U/L, base excess 〉 -5, CT severity index 〉 3 and APACHE score 〉 8 were related to morbidity and mortality.CONCLUSION: APACHE Ⅱ score, LDH, base excess and CT severity index have prognostic value and CRP is a reliable marker for predicting both mortality and morbidity. 展开更多

AIM: To investigate the efficacy and safety of ulinastatin for patients with acute lung injury(ALI) and those with acute respiratory distress syndrome(ARDS).METHODS: A systematic review of randomized controlled trials(RCTs) of ulinastatin for ALI/ARDS was conducted. Oxygenation index, mortality rate [intensive care unit(ICU) mortality rate, 28-d mortality rate] and length of ICU stay were compared between ulinastatin group and conventional therapy group. Meta-analysis was performed by using Rev Man 5.1.RESULTS: Twenty-nine RCTs with 1726 participants were totally included, the basic conditions of which were similar. No studies discussed adverse effect. Oxygenation index was reported in twenty-six studies(1552 patients). Ulinastatin had a significant effect in improving oxygenation [standard mean difference(SMD) = 1.85, 95%CI: 1.42-2.29, P < 0.00001, I2 = 92%]. ICUmortality and 28-d mortality were respectively reported in eighteen studies(987 patients) and three studies(196 patients). We found that ulinastatin significantly decreased the ICU mortality [I2 = 0%, RR = 0.48, 95%CI: 0.38-0.59, number needed to treat(NNT) = 5.06, P < 0.00001], while the 28-d mortality was not significantly affected(I2 = 0%, RR = 0.78, 95%CI: 0.51-1.19, NNT = 12.66, P = 0.24). The length of ICU stay(six studies, 364 patients) in the ulinastatin group was significantly lower than that in the control group(SMD =-0.97, 95%CI:-1.20--0.75, P < 0.00001, I2 = 86%). CONCLUSION: Ulinastatin seems to be effective for ALI and ARDS though most trials included were of poor quality and no information on safety was provided. 展开更多

The most commonly recognized complications in cirrhotic patients include ascites, hepatic encephalopathy, variceal bleeding, susceptibility for infections, kidney dysfunction, and hepatocellular carcinoma; however, severe muscle wasting or sarcopenia are the most common and frequently unseen complications which negatively impact survival, quality of life, and response to stressor, such as infections and surgeries. At present, D&#x02019;Amico stage classification, Child-Pugh, and MELD scores constitute the best tools to predict mortality in patients with cirrhosis; however, one of their main limitations is the lack of assessing the nutritional and functional status. Currently, numerous methods are available to evaluate the nutrition status of the cirrhotic patient; nevertheless, most of these techniques have limitations primarily because lack of objectivity, reproducibility, and prognosis discrimination. In this regard, an objective and reproducible technique, such as muscle mass quantification with cross-sectional imaging studies (computed tomography scan or magnetic resonance imaging) constitute an attractive index of nutritional status in cirrhosis. Sarcopenia is part of the frailty complex present in cirrhotic patients, resulting from cumulative declines across multiple physiologic systems and characterized by impaired functional capacity, decreased reserve, resistance to stressors, and predisposition to poor outcomes. In this review, we discuss the current accepted and new methods to evaluate prognosis in cirrhosis. Also, we analyze the current knowledge regarding incidence and clinical impact of malnutrition and sarcopenia in patients with cirrhosis and their impact after liver transplantation. Finally, we discuss existing and potential novel therapeutic approaches for malnutrition in cirrhosis, emphasizing the recognition of sarcopenia in an effort to reduced morbidity related and improved survival in cirrhosis. 展开更多

OBJECTIVE: To evaluate the effectiveness and safety of the Xingnao Kaiqiao needling method for treating acute ischemic stroke.DATA SOURCES: We retrieved relevant randomized controlled trials involving Xingnao Kaiqiao acupuncture for treatment of acute ischemic stroke. The China National Knowledge Infrastructure, Weipu Information Resources System, Wanfang Medical Data System, Chinese Biomedical Literature Database, Cochrane Library, and Pub Med were searched from June 2006 to March 2016.DATA SELECTION: We analyzed randomized and semi-randomized clinical controlled trials that compared Xingnao Kaiqiao acupuncture with various control treatments, such as conventional drugs or other acupuncture therapies, for treatment of acute ischemic stroke. The quality of articles was evaluated according to the Cochrane Handbook for Systematic Reviews of Interventions(Version 5.1), and the study was carried out using Cochrane system assessment methods. Rev Man 5.2 was used for the meta-analysis of the included studies.OUTCOME MEASURES: The mortality rate, disability rate, activities of daily living(Barthel Index), and clinical efficacy were observed.RESULTS: Twelve studies met the inclusion criteria for this review. The meta-analysis showed that between Xingnao Kaiqiao acupuncture and the control treatment, Xingnao Kaiqiao acupuncture reduced the disability rate [risk ratio(RR) = 0.51, 95% confidence interval(CI) = 0.27-0.98, z = 2.03, P 〈 0.05], elevated the activities of daily living(weighted mean difference = 12.23, 95% CI: 3.66-20.08, z = 2.80, P 〈 0.005), and had greater clinical efficacy(RR = 1.61, 95% CI: 1.23-2.09, z = 3.53, P 〈 0.0004). However, there was no significant difference in mortality rate(RR = 0.61, 95% CI: 0.15-2.45, z = 0.70, P 〉 0.05). CONCLUSION: The Xingnao Kaiqiao needling method is effective and safe for acute ischemic stroke. However, there was selective bias in this study, and the likelihood of measurement bias is high. Thus, more high-quality rand 展开更多

BACKGROUND The measurement of triceps skinfold(TSF)thickness serves as a noninvasive metric for evaluating subcutaneous fat distribution.Despite its clinical utility,the TSF thickness trajectories and their correlation with overall mortality have not been thoroughly investigated.AIM To explore TSF thickness trajectories of Chinese adults and to examine their associations with all-cause mortality.METHODS This study encompassed a cohort of 14747 adults sourced from the China Health and Nutrition Survey.Latent class trajectory modeling was employed to identify distinct trajectories of TSF thickness.Subjects were classified into subgroups reflective of their respective TSF thickness trajectory.We utilized multivariate Cox regression analyses and mediation examinations to explore the link between TSF thickness trajectory and overall mortality,including contributory factors.RESULTS Upon adjustment for multiple confounding factors,we discerned that males in the‘Class 2:Thin-stable’and‘Class 3:Thin-moderate’TSF thickness trajectories exhibited a markedly reduced risk of mortality from all causes in comparison to the‘Class 1:Extremely thin’subgroup.In the mediation analyses,the Geriatric Nutritional Risk Index was found to be a partial intermediary in the relationship between TSF thickness trajectories and mortality.For females,a lower TSF thickness pattern was significantly predictive of elevated all-cause mortality risk exclusively within the non-elderly cohort.CONCLUSION In males and non-elderly females,lower TSF thickness trajectories are significantly predictive of heightened mortality risk,independent of single-point TSF thickness,body mass index,and waist circumference. 展开更多

Background:Whether the dynamic weight change is an independent risk factor for mortality remains controversial.This study aimed to examine the association between weight change and risk of all-cause and cause-specific mortality based on the Linxian Nutrition Intervention Trial(NIT)cohort.Methods:Body weight of 21,028 healthy residents of Linxian,Henan province,aged 40-69 years was measured two times from 1986 to 1991.Outcome events were prospectively collected up to 2016.Weight maintenance group(weight change<2 kg)or stable normal weight group was treated as the reference.Cox proportional hazard model was performed to calculate hazard ratios(HRs)and 95%confidence intervals(95%CIs)to estimate the risk of mortality.Results:A total of 21,028 subjects were included in the final analysis.Compared with the weight maintenance group,subjects with weight loss≥2 kg had an increased risk of death from all-cause(HR_(All-cause)=1.14,95%CI:1.09-1.19,P<0.001),cancer(HR_(Cancer)=1.12,95%CI:1.03-1.21,P=0.009),and heart disease(HR_(Heart diseases)=1.21,95%CI:1.11-1.31,P<0.001),whereas subjects with weight gain≥5 kg had 11%(HR_(Cancer)=0.89,95%CI:0.79-0.99,P=0.033)lower risk of cancer mortality and 23%higher risk of stroke mortality(HR_(Stroke)=1.23,95%CI:1.12-1.34,P<0.001).For the change of weight status,both going from overweight to normal weight and becoming underweight within 5 years could increase the risk of total death(HR_(Overweight to normal)=1.18,95%CI:1.09-1.27;HR_(Becoming underweight)=1.35,95%CI:1.25-1.46)and cancer death(HR_(Overweight to normal)=1.20,95%CI:1.04-1.39;HR_(Becoming underweight)=1.44,95%CI:1.24-1.67),while stable overweight could increase the risk of total death(HR_(Stable overweight)=1.11,95%CI:1.05-1.17)and death from stroke(HR_(Stable overweight)=1.44,95%CI:1.33-1.56).Interaction effects were observed between age and weight change on cancer mortality,as well as between baseline BMI and weight change on all-cause,heart disease,and stroke mortality(all P_(interaction)<0.01).Conclusions:Weight loss w 展开更多

Background:Given the recent updates in cancer burden estimates by GLOBOCAN 2022,this study was undertaken to provide pertinent perspectives within the context of the Human Development Index(HDI)and major world economies.Methods:Datasets sourced from GLOBOCAN encompassed cancer cases and deaths across all cancer types in 2022,alongside projections up to 2050.Cancer incidences and deaths of the top 10 cancers within China and four distinct HDI-classified regions were compared using descriptive analyses.Age-standardized incidence rates(ASIRs)and mortality rates(ASMRs)worldwide for the most prevalent cancers in 2022 across ten largest economies and four-tier HDIs were examined.The top five cancer types concerning both incidence and mortality in China were delineated by sex and age group.Results:In males,prostate cancer predominated in countries with low,high(except China),and very high HDI.Prostate and liver cancers were prominent causes of death in countries with low HDI.In females,breast and cervical cancers predominated in countries with low-to-medium HDI.Lung and colorectal cancer incidence and deaths increased with high HDI for both sexes.ASIRs and ASMRs for breast,prostate,lung,and colorectal cancers in the top 10 economies were higher than the global average.However,liver,stomach,and cervical cancers in most Western countries exhibited lower rates.In China,hematologic malignancies(43%)were prevalent among children aged 0-14 years,whereas thyroid cancer led among adolescents and young adults aged 15-39 years.Regarding incidence and mortality,lung cancer predominated for individuals over 40 years,except for females aged 40-59 years,in whom breast cancer predominated.Projected trends indicated substantial increases in new cancer cases(76.6%)and deaths(89.7%)over the next three decades.Conclusions:Infection-and poverty-related cancer burdens are offset by increased prostate,breast,colorectal,and lung cancer incidence associated with rapid societal and economic transitions.Cancer incidence and mortality patterns in 展开更多

Objective:Our aim was to prospectively evaluate the accuracy of the bedside index for severity in acute pancreatitis(BISAP)score in predicting mortality,as well as intermediate markers of severity,in a tertiary care centre in east central India,which caters mostly for an economically underprivileged population.Methods:A total of 119 consecutive cases with acute pancreatitis were admitted to our institution between November 2012 and October 2014.BISAP scores were calculated for all cases,within 24 hours of presentation.Ranson’s score and computed tomography severity index(CTSI)were also established.The respective abilities of the three scoring systems to predict mortality was evaluated using trend and discrimination analysis.The optimal cut-off score for mortality from the receiver operating characteristics(ROC)curve was used to evaluate the development of persistent organ failure and pancreatic necrosis(PNec).Results:Of the 119 cases,42(35.2%)developed organ failure and were classified as severe acute pancreatitis(SAP),47(39.5%)developed PNec,and 12(10.1%)died.The area under the curve(AUC)results for BISAP score in predicting SAP,PNec,and mortality were 0.962,0.934 and 0.846,respectively.Ranson’s score showed a slightly lower accuracy for predicting SAP(AUC 0.956)and mortality(AUC 0.841).CTSI was the most accurate in predicting PNec,with an AUC of 0.958.The sensitivity and specificity of BISAP score,with a cut-off of≥3 in predicting mortality,were 100%and 69.2%,respectively.Conclusions:The BISAP score represents a simple way of identifying,within 24 hours of presentation,patients at greater risk of dying and the development of intermediate markers of severity.This risk stratification method can be utilized to improve clinical care and facilitate enrolment in clinical trials. 展开更多
