Objective:To explore the potential categories of post-traumatic stress disorder (PTSD) trajectories in women with multiple in vitro fertilization-embryo transfer (IVF-ET) failures, and to analyze the effects of different demographic characteristics and psychological factors on the potential categories of PTSD trajectories.Methods:This was a prospective empirical research, from May 2021 to October 2022, women with IVF-ET failure ≥ 2 times in the reproductive department of Shanghai First People′s Hospital from May 2021 to October 2022 were selected as the research objects. Post-traumatic stress disorder civilian version scale was used for 4 follow-ups at 3 d (T1), 10 d (T2), 20 d (T3) after the last transplantation failure and 3 d before the next transplantation cycle (T4). Telephone follow-up and online follow-up were combined to obtain the PTSD level at 4 time points. Potential categories of PTSD score trajectories at four time points were identified using a latent category growth model, and analyze influencing factors using unordered multi classification logistic analysis.Results:Totally 196 IVF-ET women were admitted, aged (29.42 ± 4.13) years. Three PTSD trajectories were fitted in this study, including 82 cases (42%) in non-PTSD group, 61 cases (31%) in mild PTSD group and 53 cases (27%) in elevated PTSD group. Logistic regression analysis showed that age, education level, fertility pressure and marital adjustment level were the predictors of PTSD trajectory in women with multiple IVF-ET failures. Compared with the non-PTSD group, women aged ≥35 years, with lower education level and marital adjustment level were more likely to enter the elevated PTSD group ( OR=4.570, 8.540, 0.949, all P<0.05). Women aged 35 years and with greater reproductive pressure were more likely to enter the mild PTSD group ( OR=3.871, 1.063, both P<0.05). Conclusions:There is group heterogeneity in the trajectories of PTSD in women with multiple IVF-ET failures in the next transplantation cycle. Old age, low education level, high fertility pressure and poor marital adjustment can predict the trajectories of PTSD. Fertility stress and marriage adjustment are changeable variables. Medical staff can relieve women′s fertility pressure through health education and mindfulness intervention, promote a good state of marriage adjustment, and minimize the adverse effects of PTSD on the next cycle of conception.

Objective:To construct the evaluation index system of core competence of extracorporeal membrane oxygenation (ECMO) specialist nurses.Methods:Through literature search and analysis, an entry pool of the core competence evaluation index system for ECMO specialist nurses was initially formed, and 20 medical and nursing experts in acute and critical care and cardiovascular fields were selected for two rounds of correspondence from September to November 2022. According to experts' opinions, the evaluation indexes of core competence of ECMO specialist nurses were modified, and the analytic hierarchy process determined the weights of indexes at all levels.Results:A total of 20 questionnaires were sent out and 20 valid questionnaires were collected during each of the two rounds of expert correspondence consultation, with effective recovery rates of 100.00%. The expert authority coefficient of the second round was 0.86, and Kendall's harmony coefficient was 0.31 ( P<0.01). Finally, the evaluation index system of core competence of ECMO specialist nurses included five primary indexes (clinical professional ability, communication and collaboration ability, nursing management ability, critical thinking ability, and professional development ability), 15 secondary indexes, and 53 tertiary indexes. Conclusions:The evaluation index system of core competence of ECMO specialist nurses constructed in this study is scientific and practical, providing a reference for evaluating ECMO specialist nurses' core competence.

Acute respiratory distress syndrome (ARDS) is a common cause of death in critically ill patients. At present, the pathogenesis of ARDS has not been clarified, which is mainly related to excessive inflammatory response, increased endothelial and epithelial permeability, and decreased alveolar surfactant. In recent years, many studies have shown that mitochondrial DNA (mtDNA) is involved in the occurrence and development of ARDS by inducing inflammation and activating immune response, and has the potential to be used as biomarkers for ARDS. This article reviews the role of mtDNA in the pathogenesis of ARDS, aiming to provide new strategies for the treatment of ARDS, and ultimately reduce the mortality of ARDS patients.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Objective:To investigate the cognitive status of nurses at different levels of comprehensive hospitals in Zhuhai regarding dysphagia in the elderly and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 554 nurses from departments with frequent dysphagia in 8 general hospitals in Zhuhai were selected as the research objects from June to July 2021. The Self-made General Data Questionnaire and Questionnaire of Nurses' Cognition of Dysphagia in the Elderly were used to investigate. Multiple stepwise linear regression analysis was used to analyze the factors influencing nurses' cognition of dysphagia in the elderly. A total of 554 questionnaires were collected in this study, of which 515 were valid, with an effective rate of 92.96%.Results:The total cognitive score of 515 elderly nurses with dysphagia was 94.64 (87.50, 100.00). Multiple stepwise linear regression analysis showed that hospital level, frequency of dysphagia knowledge training, and initial education background of nurses were the influencing factors for nurses' cognition of dysphagia in the elderly ( P<0.05) . Conclusions:The higher the hospital level, the more the training times and the higher the initial education background of nurses, the higher the cognition level of elderly patients with dysphagia.

Objective:To study the predictive value of total serum bilirubin (TSB) and the ratio of bilirubin to albumin (B/A) in neonatal acute bilirubin encephalopathy (ABE).Methods:Neonates with extremely severe hyperbilirubinemia (TSB≥425 μmol/L) treated in the Nanjing Maternal and Child Health Hospital, Maternity and Child Health Care of Guangxi Zhuang Autonomous Region, Northwest Women and Children's Hospital, Yinchuan Maternal and Child Health Hospital and Liaocheng People's Hospital from March 2018 to August 2019 were selected as prospective subjects for this study. According to the score of brain injury induced by bilirubin, the subjects were divided into ABE group and non-ABE group, and the predictive value of TSB peak and B/A for neonatal ABE were analyzed.Results:A total of 194 infants with extremely severe hyperbilirubinemia were recruited in this study, including 20 in ABE group and 174 in non-ABE group. The peak value of bilirubin ranged from 427 to 979 μmol/L. The optimal critical values of TSB peak value and B/A for ABE prediction were 530 μmol/L and 9.48, respectively. The sensitivity and specificity of ABE prediction were 85.0% and 92.8% when combined with TSB peak and B/A values.Conclusions:TSB peak combined with B/A value can effectively identify neonatal ABE. When the TSB peak value was greater than 530 μmol/L and the B/A value was greater than 9.48, the neonates had a higher risk of neonatal ABE.

Objective:To analyze fetoscopic cord laser therapy for management of monochorionic monoamniotic (MCMA) twin pregnancies.Methods:The clinical data of fetoscopic cord laser therapy, including cord occlusion, transection, and disentanglement in three pairs of MCMA twins from January 2020 to January 2021 in Peking University Third Hospital were summarized. Literature on cord occlusion and/or transection in MCMA twins were retrieved from Cochrane Library, PubMed, EMBASE, CBM, WanFang, and CNKI from the time at establishment to December 2020. The clinical conditions, surgical indications and methods, disease progression, and maternal and infant prognosis were analyzed.Results:Three cases of MCMA twins in this study period received fetoscopic cord laser therapy between 17-24 weeks, among which two cases gave birth at full-term without any maternal or infant complications, and one was terminated due to fetal malformation. Seven English articles including 29 MCMA twin pregnancies were retrieved. In addition to the three cases reported in this article, a total of 32 cases were analyzed. The indication of cord occlusion and/or transection included twin-reversed arterial perfusion sequence (21.9%, 7/32), fetal malformation (46.9%, 15/32), selective fetal growth restriction (sFGR) (21.9%, 7/32), twin-to-twin transfusion syndrome (TTTS) (3.1%, 1/32), TTTS combined with sFGR (3.1%, 1/32), single intrauterine death (3.1%, 1/32). Gestational age at surgery was between 14 +1 to 27 +3 weeks. No maternal complication due to the operation was reported. After exclusion of two cases who did not receive cord transection and one case was terminated due to fetal malformation, all the other 29 co-twins were born alive at the gestational age between 24 +3 to 40 weeks and birth weight between 800-3 800 g. Among the 29 live born babies, four died soon after birth with unclarified reasons in the literature and one was born with multiple malformations which were detected prenatally, and the other 24 neonates were healthy during the follow-up from 1 month to 9 years old. Conclusions:For MCMA twin pregnant women with umbilical cord entanglement or other indications for fetal reduction, cord occlusion, transection, and disentanglement using fetoscopic cord laser is safe and effective for protecting the surviving fetus.

Objective:To investigate the current status of emotional labor of nurses in standardized training period, and to analyze the relationship between emotional labor and emotional intelligence.Methods:From May to June 2020, 312 nurses in the standardized training period were selected as the research objects, which were investigated with general information questionnaire, Emotional Labor Scale and Emotional Intelligence Scale.Results:The total score of standardized training nurses' emotional labor was (52.27±10.18) points, and the total average score of items was (3.73±0.73) points. The average scores of the three dimensions from high to low: deep acting (4.62±0.86) points, expression of genuine emotion (3.62±0.99) points and surface acting (3.42±0.95) points. There was a correlation between emotional intelligence and emotional labor. Multiple linear regression analysis showed that the emotional evaluation of others ( β value was -0.189, P<0.05) ( β value was -0.255, P<0.01). Self emotional assessment ( β value was 0.297, P<0.01) ( β value was 0.177, P<0.05). Self emotional assessment ( β value was 0.269, P<0.05), which had a positive predictive effect on emotional expression requirements. Conclusions:The emotional labor of nurses in standardized training period is at the medium level, and the deep acting score is the highest between three dimensions. Hospital managers could promote nurses to use appropriate emotional labor strategies by strengthening the cultivation of emotional intelligence during standardized training period.
