Transfusion and Anemia Expertise Initiative-Control/Avoidance of Bleeding developed a strategy for platelet and plasma infusion management in critically ill children based on systematic reviews and consensus meetings of international multidisciplinary experts. One good practice statement and six expert consensus statements were proposed for plasma and platelet transfusions in critically ill children following severe trauma, traumatic brain injury, and/or intracranial hemorrhage. This article introduces the specific methods and basis for the formation of recommendations in this part of the guide.

Objective To investigate the clinical characteristics of women with abnormal uterine bleeding(AUB)in sub-plateau regions and analyze the factors affecting their treatment methods.Methods AUB patients who were hospitalized from Jan 1,2018 to Dec 31,2022,in a sub-plateau region(Yongping County People's Hospital of Yunnan Province)with an average altitude of 1 620 meters were selected.The general clinical characteristics of the patients were summarized,and patients were classified into two categories(with or without uterine structural lesion)and nine subtypes(PALM-COEIN)according to the FIGO recommended etiological classification guidelines.Then the patients were divided into groups based on the presence or absence of uterine structural lesions,ethnic group(Han and minority),conservative drug treatment and surgical treatment groups,blood transfusion and non-blood transfusion groups.Binary Logistic regression analysis was used to identify factors affecting treatment methods.Results A total of 481 AUB patients enrolled,and the delayed consultation rate was as high as 80.46%,and the proportion of overweight and obese patients was 49.90%,which was higher than the average level among Chinese women.The main cause was AUB-O(AUB-ovulatory dysfunction),accounting for 78.59%of cases,the proportion of patients with delayed medical treatment was higher than those without delayed medical treatment(82.17%vs.74.47%).Patients who received blood transfusion were significantly younger,had lower hemoglobin(HGB)levels,fewer pregnancies,and lower BMI compared to those in the non-blood transfusion group(P<0.05).Univariate analysis showed that the surgical treatment group had older age,longer onset time,higher HGB levels,more pregnancies and deliveries,higher BMI,a higher proportion of Han ethnicity patients,lower rates of non-blood transfusion,higher rates of hypertension,and more uterine structural lesions compared to the conservative drug treatment group.Multivariate regression analysis revealed that blood transfusion treatment reduced the probability of surgical treatment.Age and uterine structural lesions were risk factors for requiring surgical treatment,for each additional year of age,the risk of undergoing surgical treatment increased by 10%.The risk of requiring surgical treatment for patients with uterine structural lesions was 2.987 times higher than for those without.Conclusion AUB patients in this sub-plateau regions have a high rate of delayed consultation and a high proportion of overweight and obesity,with AUB-O being the primary cause.Older age and the presence of uterine structural lesions were risk factors for requiring surgical treatment.

Objective:To systematically evaluate the current status and methodological quality of guideline and consensus in ovarian stimulation for in vitro fertilization (IVF), and to provide reference for the development of future guidelines and research. Methods:A systematic search was conducted in databases including PubMed, Embase, CNKI, Wanfang, Sinomed and relevant guideline websites from inceptions to October 2024. Data were extracted from the literature that met the inclusion criteria, and methodological quality was assessed using the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) tool. Descriptive analysis was performed with results presented in visual data charts.Results:A total of 23 studies were included, with 8 guidelines and 15 consensus. Totally 21 (91.3%) studies focused on the selection of ovarian stimulation protocols, with the majority concentrating on protocols for patients undergoing IVF treatment for the first cycle, and 12 (52.2%) studies focused on the selection of gonadotropin starting dosage. In terms of methodology, the average standardized scores in the 6 assessment domains of the AGREE Ⅱ tool were as follows: scope and purpose (85.1%), stakeholder involvement (66.6%), rigour of development (36.5%), clarity of presentation (70.1%), applicability (36.4%), and editorial independence (46.2%).Conclusion:Current recommendations in ovarian stimulation for IVF exhibit inconsistencies, and the methodological quality varies, which partially hinders the translation of evidence into clinical practice. Future research should further focus on the selection of ovarian stimulation protocols and gonadotropin starting dosage, promoting the update and refinement of guidelines and consensus to guide the precise treatment of ovarian stimulation.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To explore the relationship and internal path between activities of daily living(ADL),sleep quality and mental health of community elderly people in Shanghai.Methods A questionnaire survey was conducted among community residents aged 60 years and older seeing doctors in community health care center of five streets in Shanghai during Sept to Dec,2021 using convenience sampling.Activities of Daily Living(ADL),Pittsburgh Sleep Quality Index(PSQI)and 10-item Kessler Psychological Distress Scale(K10)were adopted in the survey.Single factor analysis,correlation analysis and multiple linear regression were used to analyze the data.The effect relationship between the variables was tested using Bootstrap's mediated effects test.Results A total of 1 864 participants were included in the study.The average score was 15.53±4.47 for ADL,5.60±3.71 for PSQI and 15.50±6.28 for K10.The rate of ADL impairment,poor sleep quality,poor and very poor mental health of the elderly were 23.6%,27.3%,11.9%and 4.9%,respectively.ADL and sleep quality were all positively correlated with mental health(r=0.321,P＜0.001;r=0.466,P＜0.001);ADL was positively correlated with sleep quality(r=0.294,P＜0.001).Multiple linear results of factors influencing mental health showed that ADL(β= 0.457,95%CI:0.341-0.573),sleep quality(β =0.667,95%CI:0.598-0.737)and mental health were positively correlated(P＜0.001).Sleep quality partially mediated the relationship between ADL and mental health(95%CI:0.078-0.124)with an effect size of 33.0%.Conclusion Sleep quality is a mediator between ADL and mental health among community elderly people.Improving ADL and sleep quality may improve mental health in the population.

Objective:To construct a frailty risk prediction model for elderly heart failure with preserved ejection fraction (HFpEF) patients, and to provide a new method for accurate prediction of the occurrence of frailty in clinical elderly HFpEF patients.Methods:A cross-sectional study method was used to collect clinical data related to HFpEF patients from the Department of Cardiovascular Medicine of the First Affiliated Hospital of Xinjiang Medical University from June to November 2023 using convenience sampling method, and were randomly divided into a training set and a test set in a ratio of 7∶3, based on Logistic regression, support vector machines (SVM) and random forests, respectively, to construct a frailty risk prediction model. The performance of the models was evaluated based on the area under curve (AUC), accuracy, precision, sensitivity, specificity, F1 value.Results:A total of 319 patients with HFpEF were included, 210 males and 109 females, aged 68(62,77) years, 133 of whom developed frailty (41.7%). The dataset was divided into a training set of 223 cases and a test set of 96 cases, and all three prediction models had high accuracy, and the AUC values of the Logistic regression, SVM, and random forests models were 0.874, 0.924 and 0.884, respectively, with the SVM model having the highest AUC value and the random forests model having the highest sensitivity (0.833), specificity (0.850), accuracy (0.844), and F1 value (0.872). The importance of the feature variables was further ranked based on the random forests model, and the top five feature variables were age, interleukin-6, albumin, malnutrition, hemoglobin.Conclusions:The random forests models have the best overall predictive efficacy, which is helpful for early clinical assessment and prevention of their frailty risk.

Objective To compare the bioavailability and bioequivalence of pivastatin calcium dispersive tablets in healthy Chinese subjects.Methods A single dose of pitavastatin calcium(2 mg)was orally administered to the test preparation or reference preparation under fasting and postprandial conditions,respectively.The plasma concentrations of pitavastatin calcium were measured at different time points before and after administration by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).The bioequivalence of the two formulations was evaluated.Results Subjects received pitavastatin calcium test preparation and reference preparation in fasting condition,the Cmax were(47.79±23.99)and(46.03±21.82)ng·L-1;AUC0_,were(96.56±42.64)and(97.96±35.40)ng·h·L-1;AUC0_∞ were(102.09±43.01)and(103.46±35.62)ng·h·L-1,respectively.The 90％confidence intervals of the geometric mean ratios of Cmax,AUC0_t and AUC0-∞ of pitavastin-calcium test formulation and reference formulation were 96.28％-111.16％,94.46％-101.19％and 94.77％-101.31％,respectively.Subjects received pitavastatin calcium test preparation and reference preparation in fasting condition,the Cmax were(27.32±10.68)and(28.58±11.39)ng·L-1;AUC0_t were(82.76±27.58)and(84.06±29.12)ng·h·L-1;AUC0_∞ were(87.88±26.93)and(89.29±29.18)ng·h·L-1,respectively.The 90％confidence intervals of the geometric mean ratios of Cmax,AUC0_t and AUC0_∞ of the test formulation and the reference formulation of pitavastatin calcium were 87.39％-102.10％,94.62％-101.34％and 94.88％-101.47％,respectively.All of them were within the bioequivalence range of 80.00％to 125.00％.Conclusion Two pivastatin calcium dispersion tablets were bioequivalent and safe in healthy Chinese adult subjects.

Objective To elucidate utilization patterns,cost and safety of Bruton's tyrosine kinase inhibitors(BTKi)in the real world.Methods A retrospective cohort was designed and constructed using real-world BTKi data from a single lymphoma center.Descriptive analysis was performed to describe the demographic and clinical characteristics of the population.Medicine utilization and cost were quantified by defined daily doses(DDDs)and defined daily dose cost(DDDc),respectively.A generalized estimating equation(GEE)was used to explore the potential influencing factors of platelet aggregation rate(PAR).Results The study cohort included 193 patients[median age,65 years;77(39.90％)women],most of whom received ibrutinib(n=109,56.48％),and 77.20％patients combined BTKi with chemotherapy or targeted therapy.The implementation of national negotiation policy had a large impact on medicine utilization and cost.The DDDs difference between the two BTKis was reduced from 18.55 to 1.41 times.The DDDc for ibrutinib decreased from 1 619.99 Yuan to 567.00 Yuan,and that for zanubrutinib from 706.25 Yuan to 340.00 Yuan was already lower than ibrutinib.Interruptions were more readily observed in patients treated with ibrutinib,and hematological toxicity was the main adverse drug event(ADE)leading to treatment interruption.Besides,the GEE model showed that combining BTKi with antiplatelet medication significantly decreases the PAR[β=-34.35％,95％confidence interval(CI):-41.60％--27.11％,P＜0.001].Compared to zanubrutinib,ibrutinib also notably reduces the PAR(β=-12.38％,95％CI:-24.50％--0.27％,P＜0.05).Conclusion After the implementation of national negotiation policy,there is no significant difference in the clinical preference for two BTKis.Compared with ibrutinib,zanubrutinib showed an advantage in terms of economic profile,treatment interruptions caused by ADE,and the effect on PAR.
