Objective:To analyze the predictive factors associated with late-onset sepsis(LOS) in very low birth weight infants,and to develop a risk prediction score scale applicable to these infants three days postnatal.This will provide valuable insights for early diagnosis and timely intervention.Methods:Very low birth weight infants admitted to the Children's Hospital of Fudan University from January 1,2022,to June 30,2024,were selected as research subjects.These infants were categorized into two groups:the LOS group and the non-LOS group,based on whether they developed LOS.LASSO regression analysis,alongside univariate and multivariate regression analyses,was employed to identify predictive factors for LOS in this population.A Logistic model was constructed using the optimal combination of predictive variables,and a risk assessment scale was subsequently developed.The prediction performance of the model was evaluated using the Hosmer-Lemeshow chi-square test and the receiver operating characteristic curve.Results:A total of 444 cases of very low birth weight infants were included,of which 185 had LOS and 259 did not.After screening the variables,seven independent factors were included into the model:birth weight,gestational age,tracheal intubation,abnormal skin color,abdominal distension,elevated C-reactive protein levels,and right hand perfusion index.A predictive scoring scale was developed based on the regression coefficients of each variable,with corresponding risk scores assigned as follows:1,4,3,2,1,1,and 2; a score of ≥3.5 indicated high-risk groups.The Hosmer-Lemeshow test results demonstrated that χ2 = 7.602( P = 0.473).The area under the receiver operating characteristic curve was 0.792 ( P<0.001),with a sensitivity of 73.5% and specificity of 71.0%. Conclusion:The risk score scale developed in this study exhibits significant predictive capability,providing valuable insights for clinical medical personnel to assess the risk of LOS in very low birth weight infants during the early postnatal period.

[Purpose]To analyze cancer incidence and mortality in Anhui cancer registration areas in 2019 and the trends from 2015 to 2019.[Methods]Data from 42 cancer registration areas in Anhui Province in 2019 meeting quality control requirements were collected.The incidence,mor-tality,age-standardized rates by Chinese standard population and world standard population,age-specific rate,accumulation rate(0～74 years old)and the top 10 cancers of high incidence and mortality were calculated by urban and rural areas,sexes and age groups.The standard population of China in 2000 was used for age-standardized incidence or mortality rate(ASIRC or ASMRC),and the Segi world standard population was used for age-standardized incidence or mortality rate(ASIRW or ASMRW),respectively.Joinpoint was used to analyze the incidence and mortality trends from 2015 to 2019,and the annual percentage change(APC)was estimated.[Results]In 2019,the reported incidence rate(crude rate)in Anhui cancer registration areas was 282.87/105(313.24/105 for male,251.19/105 for female),ASIRC and ASIRW were 183.85/105 and 178.94/105,respectively,with the cumulative incidence rate of 20.35％.There was no significant change in the incidence of malignant tumors from 2015 to 2019(APC=-1.00％,P＞0.05).The reported mortality rate(crude rate)was 167.20/105(214.67/105 for male,117.67/105 for female),ASMRC and ASMRW were 98.41/105 and 97.15/105,and the cumulative mortality rate was 10.68％.There was no significant change in the mortality rate of malignant tumors from 2015 to 2019(APC=-3.44％,P＞0.05).The incidence and mortality rate of lung cancer ranked the first in urban and rural popu-lations of all genders.The incidence rate of female breast cancer ranked the third and the mortali-ty rate ranked the sixth of all malignancies.The incidence and mortality of malignant tumors in men were higher than those in women,and higher in rural areas than those in urban areas,and the main cancer types of rural and urban areas tended to be the same.[Conclusion]From 2015 to 2019,there was no significant change in the incidence and mortality of malignant tumors in the cancer registration areas of Anhui Province,but it is still necessary to prevent and treat lung can-cer and female breast cancer.

In 2025,the International Association of Pancreatology(IAP),in collaboration with the American Pancreatic Association,European Pancreatic Club,Indian Pancreas Club,and Japan Pancreas Society,released the International Association of Pancreatology revised guidelines on acute pancreatitis 2025.This edition represents a comprehensive revision of the 2013 guidelines,based on high-quality evidence accumulated over the past decade,particularly randomized controlled trials.The guidelines encompass 18 key areas-including pain management,fluid therapy,nutritional support,management of infected necrosis,complication control,discharge and follow-up,and recurrence prevention-offering a total of 96 recommendations that emphasize individualized treatment.These updates provide important guidance for standardizing clinical practice and improving outcomes in acute pancreatitis,while also indicating future research directions such as the development of targeted therapies.However,some recommendations remain limited by lower evidence quality,uncertain applicability in specific clinical settings,and insufficient consideration of economic burden and cost-effectiveness.

Objective:To evaluate the effect and causality of serum metabolites on the pathogenesis of ulcerative colitis (UC), so as to provide reference for nutritional programs for patients with UC.Methods:Two-sample Mendelian randomization (MR) analysis was performed to estimate the causal relationship between serum metabolites and UC. Genome-wide association studies (GWAS) of 1 400 metabolites were performed, with the metabolites as exposure and UC as outcome. Inverse-variance weighted (IVW) was used to calculate causal estimates. Four other MR methods with different modeling assumptions including MR-Egger, weighted median, weighted mode, and simple mode were used as additional analyses to improve the stability of the results. The results were validated through heterogeneity and pleiotropy tests. Finally, the possible causal metabolites were analyzed by metabolic pathway analysis.Results:MR analysis revealed that 85 metabolites had a possible causal relationship with UC. Among them, phosphatidylglycerol 1,2-dipalmitoyl-gpc (DPPC) ( P=2.75×10 -6) and isovaleryl carnitine (C5) ( P=1.84×10 -5) were significant risk factors for UC. Metabolic pathway analysis identified 5 metabolic pathways that might be affected by these metabolites (all P<0.05), among which the porphyrin ( P=0.004) and pyrimidine metabolic pathways ( P=0.008) had higher confidence in impacting UC. Conclusions:There are causal relationships between some serum metabolites (in particular 1,2-dipalmitoyl-GPC and isovalerylcarnitine) and the risk of UC. The porphyrin and pyrimidine metabolic pathways may impact the pathogenesis of UC.

Objective To determine the clinical effect of warmed iodophor for preoperative disinfection in elderly patients undergoing laparoscopic hysterectomy.Methods A total of 84 elderly patients who underwent laparoscopic hysterectomy were selected and randomly divided into the room temperature group(disinfected with iodophor at a temperature of 24℃)and the warmed group(disinfected with iodophor at a temperature of 39℃),with 42 cases in each group.The disinfection qualification status,incision infection status,nasopharyngeal temperature,awakening time,adverse reactions,intraoperative blood loss,incision drainage volume,and hidden blood loss of patients in the two groups were compared.Results There was no statistically significant difference in the disinfection qualification rate or incision infection rate between the two groups(P>0.05).At 10 minutes,30 minutes,60 minutes after disinfection and the end of the operation,the nasopharyngeal temperatures of patients in the warmed group were significantly higher than those in the room temperature group(P<0.05).The awakening time of patients in the warmed group was significantly shorter than that in the room temperature group(P<0.05),and the incidences of intraoperative hypothermia and shivering reaction after awakening were significantly lower than those in the room temperature group(P<0.05).There was no statistically significant difference in the intraoperative blood loss or incision drainage volume of patients between the two groups(P>0.05),while the hidden blood loss of patients in the room temperature group was significantly higher than that in the warmed group(P<0.05).Conclusion The iodophor at a temperature of 39℃for preoperative disinfection in elderly patients undergoing laparoscopic hysterectomy can not only ensure the disinfection effect and surgical safety,but also effectively maintain intraoperative body temperature stability,promote postoperative awakening,and reduce hidden blood loss.
