Objective:To analyze the distribution and drug resistance of the pathogen of bloodstream infections in patients with malignancies in Shanxi Province Cancer Hospital.Methods:A retrospective case series study was conducted. A total of 8 654 patients with malignancies whose blood culture was detected in Shanxi Province Cancer Hospital between January 2019 and December 2021 were collected, and venous blood was drawn for blood culture. WHONET 5.6 software and SPSS 23.0 software were used to analyze the distribution and drug resistance of the pathogen of bloodstream infections.Results:A total of 600 (6.9%) pathogens were isolated, including 413 (68.8%) strains of Gram-negative bacteria, 168 (28.0%) strains of Gram-positive bacteria, 19 (3.2%) strains of fungi. The top 5 gram-negative bacteria were Escherichia coli (37.7%), Klebsiella pneumoniae (14.2%), Enterobacter cloacae (4.5%), Pseudomonas aeruginosa (3.0%), and Acinetobacter baumannii (2.5%). The top 5 gram-positive bacteria were Staphylococcus aureus (4.2%), Enterococcus faecium (4.0%), Staphylococcus hominis (3.8%), Staphylococcus epidermidis (3.5%) and Streptococcus (3.0%); except Klebsiella pneumoniae, there were no statistically significant differences in the composition ratio of other major pathogens from 2019 to 2021 (all P > 0.05). The resistance rates of Escherichia coli, Klebsiella pneumoniae and Enterobacter cloacae to ampicillin were 94.7% (214/226), 100.0% (85/85) and 96.3% (26/27); the resistance rates of those to ciprofloxacin were 61.9% (140/226), 17.6% (15/85) and 7.4% (2/27); and the resistance rates of those to cefoperazone were 62.4% (141/226), 30.6% (26/85) and 25.9% (7/27), respectively. The resistance rates of P. aeruginosa and Acinetobacter baumannii to carbapenems were 5.5% (1/18) and 93.3% (14/15). Staphylococcus aureus, Staphylococcus hominis, Staphylococcus epidermidis were predominantly Staphylococcus. Enterococcus faecium and Enterococcus faecalis were the main types of enterococcus. Positive blood culture samples were mainly distributed in hematology department and intensive care unit. Non-Hodgkin lymphoma (39 strains) and acute myeloid leukemia (12 strains) were the main diseases. Conclusions:The main pathogen of bloodstream infection in patients with malignancies in this area is Gram-negative bacteria, and drug resistance is common. Hospitals should rationally use antibiotics by combining with drug sensitivity test.

Objective:To explore the oral health behavior cognition and care experience of the primary caregivers for children with ectodermal dysplasia.Methods:From February to April 2023, purposive sampling was used to select 10 primary caregivers of children with ectodermal dysplasia who visited the Department of Dental Implantation of the Affiliated Stomatological Hospital of Nanjing Medical University as the research subject. Semi-structured interviews were used to collect data, and Colaizzi 7-step analysis method was used to sort out and analyze the data.Results:The oral health behavior cognition of the primary caregivers for children with ectodermal dysplasia were summarized into three themes, including incomplete oral health behavior cognition, insufficient emphasis on continuity of health education, and high expectations for disease treatment effectiveness. The care experience was summarized into three themes, namely insufficient family and social support, excessive psychological pressure, and feeling confused and unable to cope with the education and guidance of the child.Conclusions:There are many misconceptions among the primary caregivers of children with ectodermal dysplasia regarding oral health behaviors, including insufficient cognition, high psychological pressure, and numerous care issues. We should strengthen the knowledge training of caregivers through various means, increase their cognitive level, attach importance to their psychological guidance, enhance their emotional response ability, reduce the burden of care and improve their care experience.

Objective To investigate the incidence and severity of symptoms in patients with gastric cancer who received chemotherapy,we constructed a symptom network to explore core symptoms and bridge symptoms.Furthermore,the study explores the association between core symptoms and Traditional Chinese Medicine(TCM)constitutions.Methods Patients with gastric cancer who received chemotherapy in the medical oncology and surgical oncology department from March to August 2023 were selected for the study using a convenience sampling method.The MD Anderson Symptom Inventory Gastrointestinal Cancer was used for evaluating gastrointestinal symptoms and their severity among patients receiving chemotherapy for gastric cancer,as well as assessing the classification of TCM constitution among patients.The symptom network model was constructed using the R programming language,and the central index was analyzed to determine the core symptoms and bridge symptoms.Binary logistic regression analysis was employed to assess the association between different physical conditions and the occurrence of core symptoms.Results A total of 346 electronic questionnaires were collected,with 340 valid ones,and the effective recovery rate was 98.3％.The 3 most prevalent and severe symptoms among the 340 patients with gastric cancer were fatigue(85.59％),lack of appetite(82.35％),and taste alteration(81.18％).The centrality index results indicated that grief exhibited the highest intensity,medium,and compactness centrality values(rs=8.23,rb=2.00,rc=0.03),making it the core symptom of this condition.Sleep disorders,lack of appetite,drowsiness,and taste alteration were identified as bridging symptoms with bridge intensities of 0.74,0.76,0.99,and 0.94 respectively.The results of Spearman correlation analysis showed that there was a positive correlation between sadness and qi-deficiency constitution,phlegm-dampness constitution(P＜0.05).The phlegm-dampness constitution was positively correlated with the taste alterations(P＜0.05).Conclusion In patients with gastric cancer,fatigue emerges as the most prominent symptom,while sadness assumes the core symptom.Additionally,sleep disorder,lack of appetite,drowsiness,and taste alteration are bridge symptoms.According to the principles of TCM constitution,qi-deficiency and phlegm-dampness are constitutions associated with a higher risk of experiencing sadness,and phlegm-dampness is a constitution associated with a higher risk of taste changes.Nurses can integrate core symptoms and TCM constitutions characteristics to optimize the strategies for symptom intervention.

Objective:To examines the social health status and influencing factors affecting the elderly population in urban communities of Beijing, based on the "the Standard for Healthy Chinese Older Adults(2022)" .Methods:Using the stratified sampling method, a total of 159 elderly individuals aged 60 and above from the Lanyuan community in the Malianwa street jurisdiction of Haidian district, Beijing, were selected as research subjects.The average age of the participants was(70.7±7.9)years, comprising 74 males and 85 females.Household face-to-face interviews were conducted, utilizing self-compiled questionnaires to perform a comprehensive assessment and analysis of the social health status of the elderly.Results:In the study involving community-based elderly participants, 32.1%(51 cases)were classified as healthy.The analysis revealed statistically significant differences in the social health status among various age groups of the elderly( χ2=11.802, P=0.019), with a notable downward trend in social health status as age increases( χ2=9.626, P=0.002).Furthermore, the results of multivariate Logistic regression analysis indicated that educational level( OR=2.119, 95% CI: 1.044-4.031, P=0.038)and chronic disease status( OR=5.007, 95% CI: 1.083-23.140, P=0.039)are significant influencing factors on the social health status of older adults. Conclusions:The social health status of the elderly in urban communities in Beijing is generally low and deteriorates progressively with age.Both educational attainment and chronic disease prevalence significantly influence the social health of this demographic.For elderly individuals with lower educational levels and poor chronic disease management, it is essential to conduct social health assessments and implement targeted intervention strategies to enhance their overall social health.

Objective:To explore the drugs and clinical characteristics causing drug-induced liver injury (DILI) in recent years, as well as identify drug-induced liver failure, and chronic DILI risk factors, in order to better manage them timely.Methods:A retrospective investigation and analysis was conducted on 224 cases diagnosed with DILI and followed up for at least six months between January 2018 and December 2020. Univariate and multivariate logistic regression analyses were used to identify risk factors for drug-induced liver failure and chronic DILI.Results:Traditional Chinese medicine (accounting for 62.5%), herbal medicine (accounting for 84.3% of traditional Chinese medicine), and some Chinese patent medicines were the main causes of DILI found in this study. Severe and chronic DILI was associated with cholestatic type. Preexisting gallbladder disease, initial total bilirubin, initial prothrombin time, and initial antinuclear antibody titer were independent risk factors for DILI. Prolonged time interval between alkaline phosphatase (ALP) and alanine aminotransferase (ALT) falling from the peak to half of the peak (T 0.5ALP and T 0.5ALT) was an independent risk factor for chronic DILI [area under the receiver operating characteristic curve (AUC)?=?0.787, 95%CI: 0.697~0.878, P ?

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the efficacy of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects who were previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extended or switched TMF treatment for 48 weeks. Efficacy was evaluated based on virological, serological, biological parameters, and fibrosis staging. Statistical analysis was performed using the McNemar test, t-test, or Log-Rank test according to the data. Results:593 subjects from the initial TMF group and 287 subjects from the TDF group were included at week 144, with the proportions of HBV DNA<20 IU/ml at week 144 being 86.2% and 83.3%, respectively, and 78.1% and 73.8% in patients with baseline HBV DNA levels ≥8 log10 IU/ml. Resistance to tenofovir was not detected in both groups. For HBeAg loss and seroconversion rates, both groups showed a further increase from week 96 to 144 and the 3-year cumulative rates of HBeAg loss were about 35% in each group. However, HBsAg levels were less affected during 96 to 144 weeks. For patients switched from TDF to TMF, a substantial further increase in the alanine aminotransferase (ALT) normalization rate was observed (11.4%), along with improved FIB-4 scores.Conclusion:After 144 weeks of TMF treatment, CHB patients achieved high rates of virological, serological, and biochemical responses, as well as improved liver fibrosis outcomes. Also, switching to TMF resulted in significant benefits in ALT normalization rates (NCT03903796).

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the safety profile of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects that previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extending or switching TMF treatment for 48 weeks. Safety profiles of kidney, bone, metabolism, body weight, and others were evaluated.Results:666 subjects from the initial TMF group and 336 subjects from TDF group with at least one dose of assigned treatment were included at week 144. The overall safety profile was favorable in each group and generally similar between extended or switched TMF treatments from week 96 to 144. In subjects switching from TDF to TMF, the non-indexed estimated glomerular filtration rate (by non-indexed CKD-EPI formula) and creatinine clearance (by Cockcroft-Gault formula) were both increased, which were (2.31±8.33) ml/min and (4.24±13.94) ml/min, respectively. These changes were also higher than those in subjects with extending TMF treatment [(0.91±8.06) ml/min and (1.30±13.94) ml/min]. Meanwhile, switching to TMF also led to an increase of the bone mineral density (BMD) by 0.75% in hip and 1.41% in spine. On the other side, a slight change in TC/HDL ratio by 0.16 (IQR: 0.00, 0.43) and an increase in body mass index (BMI) by (0.54±0.98) kg/m 2 were oberved with patients switched to TMF, which were significantly higher than that in TMF group. Conclusion:CHB patients receiving 144 weeks of TMF treatment showed favorable safety profile. After switching to TMF, the bone and renal safety was significantly improved in TDF group, though experienceing change in metabolic parameters and weight gain (NCT03903796).

Objective To investigate the clinical features and risk factors for deep vein thrombosis(DVT)of the lower ex-tremities in burn patients.Methods The clinical data of 155 burn patients admitted to Wuhan Third Hospital from January 2021 to January 2023 were retrospectively analyzed.The patients were divided into DVT group and non-DVT group according to whether they had concurrent DVT during hospitalization.Two groups of baseline data were compared[sex,age,body mass in-dex(BMI),coexisting diseases,smoking,drinking,DVT history of the lower limbs,burn cause,burn site,burn degree,central venous catheter retention in the femoral vein,wound infection,low-molecular-weight heparin application,time in bed,and labora-tory indicators[D-dimer(D-d),fibrinogen(FIB),homocysteine(Hey)].The levels of tumor necrosis factor α(TNF-α)and C-reac-tive protein(CRP)differed,and the risk factors for DVT in burn patients were determined via multivariate logistic regression a-nalysis.Finally,this study analyzed the value of BMI,time in bed,D-dimer,fibrinogen,Hcy,TNF-α,and CRP in predicting DVT in burn patients via receiver operating characteristic(ROC)curves.Results There were no significant differences between the two groups in terms of sex,combined disease,smoking or drinking,or cause of burn(all P＞0.05).The following risk factors were found to be significantly greater in the group with deep vein thrombosis(DVT)than in the group without DVT:age 60 years or older,history of lower limb DVT,lower limb burn of degree Ⅱ or above covering 30％or more of the area,femoral vein indentation central venous catheter,wound infection,and lack of low-molecular-weight heparin treatment.Additionally,BMI,D-dimer levels,fibrinogen levels(FIB),homocysteine(Hcy)levels,TNF-α levels,and C-reactive protein(CRP)levels were signifi-cantly higher in the DVT group than in the non-DVT group.The time in bed was significantly longer in the DVT group than in the non-DVT group(P＜0.01).Multivariate logistic regression analysis confirmed that the risk factors for DVT in burn pa-tients included age ≥60 years,history of lower extremity DVT,lower extremity burn,burn degree Ⅱ or above,burn area≥30％,femoral vein indwelling central venous catheter,wound inf ection,lack of low-molecular-weight heparin application,increased BMI,elevated levels of D-dimer,FIB,Hcy,TNF-α,and CRP,and prolonged time in bed.ROC analysis confirmed that BMI,time in bed,D-d,FIB,Hcy,TNF-α and CRP could all be used to predict DVT in burn patients,and the areas under the curve were 0.844,0.853,0.890,0.817,0.892,0.962 and 0.776,respectively,(all P＜0.01).Conclusion Burn patients complicated with DVT are affected by many factors.Moreover,ROC analysis confirmed that BMI,time in bed,D-d,FIB,Hcy,TNF-α and CRP could be indicators for predic-ting DVT,which should be considered in the subsequent clinical treatment of such patients.

Objective To explore the factors influencing the pregnancy rate after fallopian tube recanalization(FTR),and to construct and validate a nomogram prediction model.Methods The clinical data of a total of 322 female patients with tubal obstructive infertility,who received FTR at the Wuhan Municipal Third Hospital of China between January 2018 and December 2022,were retrospectively analyzed.According to whether the female patient had natural pregnancy or not within 12 months after FTR treatment,the female patients were divided into the pregnant group and the non-pregnant group.Logistic regression analysis was used to determine the independent factors influencing pregnancy.The female patients were randomly divided into training group and validation group at 1∶1 ratio.A nomogram model was constructed in the training group,and the predictive efficacy of the model was verified in the validation group by using receiver operating characteristic(ROC)curves,calibration curves and decision curve analysis(DCA).Results The natural pregnancy rate at one year after FTR was 45.34％(146/322).Age＞35 years,primary infertility,duration of infertility＞3 years,distal fallopian tube obstruction,and moderate to severe tubal lesion were the independent risk factors affecting the pregnancy rate after FTR(all P＜0.05).The constructed nomogram model had a good differentiation and calibration ability and it carried a high degree of clinical utility.Conclusion The nomogram model constructed in this study can effectively predict the risk of infertility within one year after FTR treatment,which is helpful for formulating the individualized therapeutic scheme for infertility female patients.

Pancreatic cancer is one of the most malignant tumors with a 5-year survival rate of 13%. Difficulty in early diagnosis,high tumor heterogeneity,high rate of drug resistance,and lack of effective new drugs are the main reasons for the poor therapeutic effect. Traditional cell line models cannot simulate the tumor environment in vitro and cannot reflect the heterogeneity of pancreatic cancer,while animal models have a long culture process and cannot be used for high-throughput screening. Pancreatic cancer organoids can be continuously expanded and cultured in vitro,which can realistically reflect the heterogeneity of pancreatic cancer and allow high-throughput drug screening,making it an ideal tool for individualized precision diagnosis and treatment of pancreatic cancer. According to recent studies on the evaluation of clinical drug efficacy using pancreatic cancer organoids,the drug sensitivity of pancreatic cancer organoids is highly consistent with the clinical efficacy,demonstrating the feasibility of drug sensitivity of pancreatic cancer organoids in guiding clinical therapy,comfirming the ability to discover potential therapeutic drugs through high-throughput drug screening of pancreatic cancer organoids. At the same time,this review reveals the importance of pancreatic cancer organoids as a model of the pancreatic cancer microenvironment for the development of new drugs and tumor microenvironment research. and the role of pancreatic cancer organoids as a model that can reflect the specific microenvironment of pancreatic cancer for new drug discovery and microenvironmental evaluation. Pancreatic cancer organoids and organ-on-chips are powerful tools for precision companion therapy and new drug discovery.
