To summarize the nursing experience of 5 patients with severe ARDS complicated with hypercapnia who underwent extracorporeal carbon dioxide removal(ECCO2R).Key points of nursing care included:establishing a rapid emergency response nursing team for ECCO2R;PETCO2 real-time monitoring to grasp the timing of the machine;ensuring continuity of treatment and improving the removal efficiency;respiratory-related monitoring;prevention of complications of blood coagulation and hypothermia;and weaning from extracorporeal carbon dioxide removal.After careful treatment and care,all the 5 patients were successfully removed from ECCO2R treatment.

This article reports a case diagnosed with a large placental chorioangioma during the mid-trimester of pregnancy. The condition of this case progressed rapidly, with complications of edema, severe anemia, and severe heart failure, presenting a critical condition. After multidisciplinary consultation and discussion, amniotic fluid reduction and intrauterine fetal blood transfusion were performed at 27 weeks and 1 day of gestation to alleviate maternal and fetal symptoms. An emergency cesarean section was performed due to placental abruption 25 h after the operation, delivering an extremely preterm infant. The infant was diagnosed with fetal/newborn alloimmune thrombocytopenia caused by positive anti-human leukocyte antigen (HLA) antibodies after ineffective multiple platelet transfusions within three days after birth. The infant's condition improved after the transfusion of platelets negative for anti-HLA antibodies. This case was complicated by multiple high-risk factors, with an extremely high risk of fetal and postnatal death. Successful rescue through multidisciplinary collaboration was achieved, and both mother and child recovered well after the operation. It suggests that in clinical practice, attention should be paid to large chorioangiomas, and regular monitoring of the chorioangioma and fetal intrauterine development is necessary. For fetuses and newborns with thrombocytopenia, especially those with ineffective platelet transfusions, the detection of platelet antibodies should be emphasized, and while considering anti-platelet specific antibodies, the role of HLA antibodies should also be considered.

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 clinical and genetic characteristics of patients with Ehlers-Danlos syndrome (EDS) and gastrointestinal involvement.Methods:We retrospectively collected the clinical data of patients with EDS and gastrointestinal involvement from the electronic medical records at Peking Union Medical College Hospital (PUMCH) from January 2003 to September 2023. Additionally, we conducted a systematic review by searching cases with EDS and gastrointestinal involvement in PubMed, Embase, Web of Science, and the Cochrane Library databases from January 2000 to September 2023.Results:Ninety-four patients with EDS and gastrointestinal involvement were retrieved, including five patients from PUMCH and 89 patients from 80 published articles. The average age of patients was (29±14) years. The most common manifestation of gastrointestinal involvement was gastrointestinal perforation ( n=46, 48.9%), followed by functional gastrointestinal symptoms ( n=33, 35.1%), and digestive arterial disorders ( n=10, 10.6%). The most common clinical subtype was vascular-EDS (vEDS) ( n=50, 53.2%) followed by hypermobile-EDS (hEDS) ( n=20, 21.3%). The most frequent genetic mutation occurred in the COL3A1 gene ( n=30, 31.9%). Among patients with vEDS, gastrointestinal manifestations included gastrointestinal perforation ( n=33, 66.0%), arterial lesions ( n=9, 18.0%), and functional gastrointestinal symptoms ( n=7, 14.0%). Among patients with hEDS, gastrointestinal manifestations included functional gastrointestinal symptoms ( n=18, 90.0%), visceral prolapse ( n=3, 15.0%) and intestinal volvulus ( n=1, 5.0%). Conclusions:The most common subtypes of gastrointestinal involvement in EDS were vEDS and hEDS. Patients with hEDS mainly presented with functional gastrointestinal symptoms, whereas those with vEDS primarily showed gastrointestinal perforation and digestive arterial disorders.

Objective:To investigate the intention to stay on among primary health care workers (PHWs) during the COVID-19 epidemics and its influencing factors.Methods:An online questionnaire survey was conducted among PHWs from 62 primary health institutions in 31 provinces, autonomous regions and municipalities across China selected by multi-stage whole cluster random sampling method between May and October 2022. According to the job position, the PHWs were divided into 5 categories: general practitioners (GPs), nurses, public health doctors, managers and support staff. Intention to stay was measured using the Chinese version of the Intention to Stay Questionnaire. Multiple linear regression model was used to analyze the influencing factors of the intention to stay in PHWs of different occupational categories, including personal factors, work factors, factors related to the COVID-19 and psychological reactions.Results:A total of 3 769 PHWs from 44 community health service centers, 18 township hospitals of 27 provinces/autonomous regions and 4 municipalities participated in this survey. The mean age of participants was (37.4±9.2) years, including 2 971(78.8%) women. The mean score of intention to stay of participants was 21.7±4.1. Compared with GPs, managers had lower intention to stay ( P=0.004). Age, female, in marriage, monthly income, years of primary care service, self-evaluation of unit support function, MSQ-SF score, and PA score were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 score, EE score, and DP score were negatively correlated with the score of intention to stay (all P<0.05). The MSQ-SF scores of all occupational categories were positively correlated with the scores of intention to stay (all P<0.01). In addition, among GPs, monthly income, years of service in primary care, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 scores and EE scores were negatively correlated with the score of intention to stay (all P<0.05). Among nurses, age, female gender, monthly income, self-evaluation of unit support function, and PA score were positively correlated with the score of intention to stay (all P<0.05), while EE scores and retention will score were negatively associated with ( P<0.001). Among public health doctors, in marriage was positively correlated with the score of intention to stay ( P=0.018). Among managers, DP score was negatively correlated with the score of intention to stay ( P=0.001). Among support staff, female gender, monthly income, years of primary care service, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while EE score and DP score were negatively correlated with intention to stay (all P<0.05). Conclusions:The intention to stay of PHWs in China during the COVID-19 was at an intermediate level, which was affected by many factors. Among them, job satisfaction was positively correlated with the intention to stay of all occupational categories, and the influencing factors of different occupational categories have some variations.

Objective:To investigate the effect of capsaicin on lipopolysaccharide(LPS)-induced microglial inflammatory response by modulating silent mating type information regulation 2 homolog 1(SIRT1)/high mobility group box-1 protein(HMGB1)/nuclear factor κB(NF-κB)signaling pathway.Methods:BV2 mouse microglia were cultured in vitro,and pretreated with capsaicin(10 μmol/L),SIRT1 inhibitor EX527(100 μmol/L),capsaicin+EX527(10 μmol/L capsaicin+100 μmol/L EX527)for 3 hours,and then treated with LPS(1 μg/ml)for 24 hours,the corresponding groups were LPS group,LPS+capsaicin group,LPS+EX527 group,and LPS+capsaicin+EX527 group,a normal cultured control group(Control)was also set up.Morphological changes of BV2 cells in each group were observed under a microscope;CCK-8 method was used to detect the viability of BV2 cells in each group;immunofluo-rescence staining was applied to detect the positive expressions of ionic calcium adaptor protein(Iba-1)and the polarization of M1(positive for CD16/32)/M2(positive for CD206)subtypes in BV2 cells in each group;ELISA was applied to detect levels of inflamma-tory factors in BV2 cells in each group;Western blot and co-immunoprecipitation were applied to detect expression of SIRT1/HMGB1/NF-κB signaling pathway-related proteins in each group.Results:Compared with Control group,BV2 cells in LPS group were atro-phied,with shortened processes,the cell viability,and levels of IL-1β,TNF-α and IL-6 were increased,Iba-1 positive expression of BV2 cells and M1 type BV2 cells were increased,while expression of SIRT1 protein was decreased,expressions of acetylated(ace)-HMGB1 protein,cytoplasmic HMGB1 protein and nuclear NF-κB protein were increased(P<0.05);after capsaicin pretreatment,the above conditions were improved,and the M2 type BV2 cells were increased;adding EX527 pretreatment on the basis of capsaicin pre-treatment,the above conditions were all aggravated.Conclusion:Capsaicin can inhibit the inflammatory response induced by LPS-in-duced BV2 cell activation,which may be achieved by modulating the SIRT1/HMGB1/NF-κB signaling pathway.

Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.

BACKGROUND: This study aimed to develop a comprehensive instrument for evaluating and ranking clinical practice guidelines, named Scientific, Transparent and Applicable Rankings tool (STAR), and test its reliability, validity, and usability. METHODS: This study set up a multidisciplinary working group including guideline methodologists, statisticians, journal editors, clinicians, and other experts. Scoping review, Delphi methods, and hierarchical analysis were used to develop the STAR tool. We evaluated the instrument's intrinsic and interrater reliability, content and criterion validity, and usability. RESULTS: STAR contained 39 items grouped into 11 domains. The mean intrinsic reliability of the domains, indicated by Cronbach's α coefficient, was 0.588 (95% confidence interval [CI]: 0.414, 0.762). Interrater reliability as assessed with Cohen's kappa coefficient was 0.774 (95% CI: 0.740, 0.807) for methodological evaluators and 0.618 (95% CI: 0.587, 0.648) for clinical evaluators. The overall content validity index was 0.905. Pearson's r correlation for criterion validity was 0.885 (95% CI: 0.804, 0.932). The mean usability score of the items was 4.6 and the median time spent to evaluate each guideline was 20 min. CONCLUSION The instrument performed well in terms of reliability, validity, and efficiency, and can be used for comprehensively evaluating and ranking guidelines.

Objective:To investigate the value of net water uptake (NWU) for predicting early neurological improvement (ENI) after endovascular treatment in patients with acute anterior circulation large vessel occlusion stroke.Methods:A case-control study. A total of 132 patients (80 men, 52 women, median age 68 years) with acute anterior circulation large vessel occlusive stroke receiving endovascular treatment were retrospectively analyzed at Jinling Hospital from October 2014 to September 2019. Patients were divided into two groups based on the occurrence of ENI, which was defined as either an improvement of NIHSS score of ≥4 points, or an NIHSS score of 0 or 1 at 24 hours after endovascular treatment. The rank sum test, Chi square test, and other methods were used to compare differences in baseline characteristics between the two groups. Logistic regression analysis was used to investigate independent predictors of postoperative ENI. Receiver operating characteristic curve analysis used to assess the capacity of NWU to predict ENI.Results:Of the 132 patients in the study, ENI occurred in 47 and did not occur in 85. In multivariate logistic regression analysis age [odds ratio ( OR)=0.940, 95% confidence interval ( CI) 0.903-0.979, P=0.003], time from stroke onset to puncture ( OR=0.995, 95% CI 0.991-0.999, P=0.025), time from puncture to recanalization/end of operation ( OR=0.985, 95% CI 0.974-0.996, P=0.007), NWU ( OR=0.762, 95% CI 0.620-0.937, P=0.010), and mTICI ( OR=1.644, 95% CI 1.043-2.590, P=0.032) were predictive factors for ENI. Receiver operating characteristic curve analysis indicated that NWU could effectively predict ENI (area under the curve=0.642, 95% CI 0.543-0.741, P=0.007), and prediction accuracy was improved when it was combined with other clinical parameters. Conclusion:NWU is an independent predictor of ENI in patients with acute anterior circulation large vessel occlusive stroke undergoing endovascular treatment.

To compare different illness severity scores in predicting mortality risk of extremely low birth weight infants (ELBWI). From January 1st, 2019 to January 1st, 2020, all ELBWI admitted in the Children's Hospital of Nanjing Medical University, Nanjing Maternity and Child Health Care Hospital and the First Affiliated Hospital of Nanjing Medical University were included in the study. ELBWI with admission age ≥1 h, gestational age ≥37 weeks and incomplete data required for scoring were excluded. The clinical data were collected, neonatal critical illness score (NCIS), score for neonatal acute physiology version Ⅱ (SNAP-Ⅱ), simplified version of the score for neonatal acute physiology perinatal extension (SNAPPE-Ⅱ), clinical risk index for babies (CRIB) and CRIB-Ⅱ were calculated. The scores of the fatal group and the survival group were compared, and the receiver operating characteristic (ROC) curve was used to evaluate the predictive value of the above illness severity scores for the mortality risk of ELBWI. Pearson correlation analysis was used to analyze the correlation between illness scores and birth weight, illness scores and gestational age. A total of 192 ELBWI were finally included, of whom 114 cases survived (survival group) and 78 cases died (fatal group). There were significant differences in birth weight, gestational age and Apgar scores between fatal group and survival group (all <0.01). There were significant differences in NCIS, SNAP-Ⅱ, SNAPPE-Ⅱ, CRIB and CRIB-Ⅱ between fatal group and survival group (all <0.01). The CRIB had a relatively higher predictive value for the mortality risk. Its area under the ROC curve (AUC) was 0.787, the sensitivity was 0.678, the specificity was 0.804, and the Youden index was 0.482. The scores of NCIS, SNAP-Ⅱ, SNAPPE-Ⅱ, CRIB and CRIB-Ⅱ were significantly correlated with birth weight and gestational age (all <0.05). The correlation coefficients of CRIB-Ⅱ and CRIB with birth weight and gestational age were relatively large, and the correlations coefficients of NCIS with birth weight and gestational age were the smallest (0.191 and 0.244, respectively). Among these five illness severity scores, CRIB has better predictive value for the mortality risk in ELBWI. NCIS, which is widely used in China, has relatively lower sensitivity and specificity, and needs to be further revised.
