Establishment of in-hospital nutrition support program for middle-aged and elderly patients with acute decompendated heart failure.

OBJECTIVE: To construct a nutrition support program for middle-aged and elderly patients with acute decompensated heart failure (ADHF) during hospitalization. METHODS: Based on the JBI Evidence-Based Health Care Model as the theoretical framework, the best evidence was extracted through literature analysis and a preliminary nutrition support plan for middle-aged and elderly ADHF patients during hospitalization was formed. Two rounds of expert opinion consultation were conducted using the Delphi method. The indicators were modified, supplemented and reduced according to the expert's scoring and feedback, and the expert scoring was calculated. RESULTS: The response rates of the experts in the two rounds of consultation were 86.7% and 100%, respectively, and the coefficient of variation (CV) for each round was between 0.00% and 29.67% (all < 0.25). In the first round of expert consultation, 4 items were modified, 3 items were deleted, and 3 items were added. In the second round of the expert consultation, one item was deleted and one item was modified. Through two rounds of expert consultation, expert consensus was reached and a nutrition support plan for ADHF patients was finally formed, including 4 first-level indicators, 7 s-level indicators, and 24 third-level indicators. CONCLUSION: The nutrition support program constructed in this study for middle-aged and elderly ADHF patients during hospitalization is authoritative, scientific and practical, and provides a theoretical basis for clinical development of nutrition support program for middle-aged and elderly ADHF patients during hospitalization.

Effect of a High-Fat Diet and Probiotic Supplementation on the Gut Microbiota of Maternal Mice at Term Pregnancy and Offspring at Three-Week Postpartum.

The effects of probiotics on the gut microbiota in maternal mice-fed high-fat diet (HFD) during pregnancy and offspring are still unknown. We aimed to evaluate the effect of high-fat diet and probiotic supplementation on the gut microbiota of maternal mice at term pregnancy and offspring at three-week postpartum. Female pregnant Kunming mice were randomly divided into four groups: mice on a control diet (MC), mice on HFD (MHF), mice on a control diet and probiotics (MCP), and mice on HFD and probiotics (MHFP). The result showed that MHF had significantly reduced Bacteroidetes and Muribaculaceae (P < 0.05) and increased Firmicutes/Bacteroidetes ratio vs. MC. Lachnospiraceae_NK4A136_group and Alistipes reduced (P < 0.05), and Firmicutes/Bacteroidetes ratio significantly increased in MCP vs. MC. There was no significant difference between MHF and MHFP. Higher levels of Prevotella, Prevotellaceae, and Streptococcaceae were found in mice offspring on HFD (OHF) vs. mice offspring on a control diet (OC) (P < 0.05, respectively). Bacteroidia, Bacteroidota, Bacteroidales, and Muribaculaceae decreased markedly in mice offspring on a control diet and probiotics (OCP) vs. OC (P < 0.05, respectively), while Firmicutes, Lactobacillales, Lactobacillaceae, and Lactobacillus significantly increased in OCP (P < 0.05, respectively). There was no significant difference between the OHF and mice offspring on HFD and probiotics (OHFP). The findings suggest that the gut microbial composition of pregnant mice and offspring were altered to some extent due to HFD or probiotic intervention. Further, maternal mice on HFD and offspring were less affected by probiotic supplementation.

Analysis of clinical application effects and challenges of early warning system for the high-risk obstetric women of China: A scoping review.

BACKGROUND: Obstetric critical illness is an important factor that leads to an increase in maternal mortality. Early warning assessment can effectively reduce maternal and neonatal mortality and morbidity. However, there are multiple early warning systems, and the effect and applicability of each system in China still need to be explored. OBJECTIVES: To elaborate on the application, effectiveness and challenges of the existing early warning systems for high-risk obstetric women in China and to provide a reference for clinical practice. DESIGN: A scoping review guided by the Arksey and O'Malley framework and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for scoping review (PRISMA-ScR) guidelines. ELIGIBILITY CRITERIA: We included original studies related to early warning and excluded those that were guidelines, consensus and reviews. The included studies were published in Chinese or English by Chinese scholars as of June 2021. DATA SOURCES: CNKI, Wanfang, VIP, Cochrane, CINAHL, Embase, PubMed and Web of Science databases were searched systematically, and the reference sections of the included papers were snowballed. RESULTS: In total, 598 articles were identified. These articles were further refined using keyword searches and exclusion criteria, and 17 articles met the inclusion criteria. We extracted data related to each study's population, methods and results. Early warning tools, outcome indices, effects and challenges are discussed. CONCLUSIONS: Although all studies have shown that early warning systems have good application effects, the use of early warning systems in China is still limited, with poor regional management and poor sensitivity for specific obstetric women. Future research needs to develop more targeted early warning tools for high-risk obstetric women and address the current challenges in clinical applications.

Training load of newly recruited nurses in Grade-A Tertiary Hospitals in Shanghai, China: a qualitative study.

BACKGROUND: This study aimed to provide insight into the training load of newly recruited nurses in grade-A tertiary hospitals in Shanghai, China. The lack of nurses in hospitals across China has resulted in newly recruited nurses in grade-A tertiary hospitals in Shanghai having to integrate into the work environment and meet the needs of the job quickly; thus, they undergo several training programs. However, an increase in the number of training programs increases the training load of these nurses, impacting the effectiveness of training. The extent of the training load that newly recruited nurses have to bear in grade-A tertiary hospitals in China remains unknown. METHODS: This qualitative study was conducted across three hospitals in Shanghai, including one general hospital and two specialized hospitals, in 2020. There were 15 newly recruited nurses who were invited to participate in semi-structured in-depth interviews with the purpose sampling method. A thematic analysis approach was used to analyze the data. The COREQ checklist was used to assess the overall study. RESULTS: Three themes emerged: external cognitive overload, internal cognitive overload, and physical and mental overload. CONCLUSION: Through qualitative interviews, this study found that the training of newly recruited nurses in Shanghai's grade-A tertiary hospitals is in a state of overload, which mainly includes external cognitive overload, internal cognitive overload, physical and mental overload, as reflected in the form of training overload, the time and frequency of training overload, the content capacity of training overload, the content difficulty of training overload, physiological load overload, and psychological load overload. The intensity and form of the training need to be reasonably adjusted. Newly recruited nurses need to not only improve their internal self-ability, but also learn to reduce internal and external load. Simultaneously, an external social support system needs to be established to alleviate their training burden and prevent burnout.

Promotion factors of emergency nurses' post-traumatic growth during the COVID-19 pandemic in Shanghai: a qualitative study.

BACKGROUND: Since March 2022, Shanghai, China, has experienced a severe wave of SARS-CoV-2 transmission caused by the Omicron variant strain. The pandemic has severely constrained the local healthcare system. After treating critically ill COVID-19 patients, emergency nurses may experience some positive changes due to new insights or gains in their work, even if they have had traumatic experiences. This study aimed to explore the promoting factors of emergency nurses' post-traumatic growth during the COVID-19 pandemic in Shanghai. We hoped to provide a new perspective and theoretical basis for intervening in and promoting the psychological rehabilitation of medical staff after traumatic circumstances. METHODS: This study employed a qualitative design based on the phenomenological approach. 18 participants from the emergency department of a third-level class-A hospital in Shanghai who participated in treating COVID-19 patients were enrolled using purposive sampling. Data collection was through in-depth and semi-structured interviews and continued until reaching data saturation. The seven-step Colaizzi process was used for data analysis. RESULTS: The investigation uncovered two themes and six subthemes. Internal factors contained self-affirmation, deliberate rumination, and cognitive restructuring, which constituted attitudes and behaviours that participants could subjectively determine. External factors included social support, transformational leadership, and role modelling, which constituted factors influenced by others or the environment. CONCLUSIONS: The promoting factors of PTG of emergency nurses originated from different sources such as individuals, organizations, and society. In addition to good psychological adjustment of the individual, society, hospitals, and nursing managers should focus on establishing supportive PTG strategies. The ultimate purpose is to improve the retention rate and career growth of nurses.

Career adaptability of newly graduated nurses at an obstetrics and gynaecology hospital in China: A qualitative study.

AIM: The aim of this study was to gain insight into factors affecting career adaptability of newly graduated nurses and ways to improve them. BACKGROUND: Newly graduated nurses face an important transition from student to professional. Unfortunately, the nurse turnover rate is high due to maladaptation. Factors influencing career adaptability and improvement methods have not been clearly addressed. METHODS: Using a descriptive qualitative study with thematic analysis, 15 newly graduated nurses from a tertiary obstetrics and gynaecology teaching hospital in China were interviewed. RESULTS: Six themes affecting career adaptability were found: personality, self-confidence, occupational care focus, work-related stress, basic professional competency and gap between reality and expectations. Four themes improving career adaptability were identified: strong social support, self-adjustment, self-development and career preparation. Eight subthemes were also identified. CONCLUSIONS: Individual, family and work factors were among those affecting career adaptability among newly graduated nurses. Newly graduated nurses would improve their career adaptability through self-adjustment and social support. Helping them to promote these factors and measures is conducive to improving their career adaptability and reducing staff turnover. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers should be aware of the key factors affecting career adaptability among newly graduated nurses and design targeted improvement programmes.

Risk scoring system with MRI for intraoperative massive hemorrhage in placenta previa and accreta.

BACKGROUND: Placenta previa and accreta are serious obstetric conditions that are associated with a high risk of intraoperative massive hemorrhage. PURPOSE: To develop a scoring system for intraoperative massive hemorrhage combining MRI and clinical characteristics to predict the risk of massive hemorrhage in placenta previa and accreta STUDY TYPE: Retrospective cohort study. SUBJECTS: In all, 374 patients consisting of 259 patients with placenta previa and accreta after previous cesarean section (CS) for the derivation cohort and 115 patients for the validation cohort. FIELD STRENGTH/SEQUENCE: 1.5T single-shot fast spin-echo sequence. [Correction added on October 23, 2019, after first online publication: The field strength in the preceding sentence was corrected.] ASSESSMENT: Using the derivation cohort, clinical and MRI data were collected and multivariable logistic regressions analysis was conducted to develop a scoring system for prediction of intraoperative massive bleeding (blood loss volume > 2000 mL). Finally, the scoring system was validated on 115 patients. STATISTICAL TESTS: Student's t-test, Mann-Whitney U-test, X 2 statistics, multivariable analysis, and receiver operating characteristic (ROC) analysis. RESULTS: Ten indicators, including clinically maternal age (1 point), preoperative hemoglobin level (1 point), gravidity number (1 point), number of CS (1 point), and MRI T2 dark intraplacental bands (4 points), cervical canal length (3 points), placenta thickness on the uterine scar area (4 points), empty vascular shadow of the uterus (1 point), low signal discontinuity in the muscular layer of the posterior wall of the bladder (6 points) and attachment position of the placenta (1 point) were imputed. From the ROC analysis, a total score of 7 points was identified as the optimal cutoff value, allowing good differentiation of intraoperative massive bleeding in the derivation cohort (AUC, 0.863; 95% confidence interval [CI]: 0.811-0.916) and in the validation cohort (AUC, 0.933; 95% CI: 0.885-0.980). DATA CONCLUSION: The scoring system for intraoperative massive hemorrhage consists of MRI and clinical indicators, and using a cutoff value of 7 points for a high risk of massive bleeding, the developed scoring system could accurately assess the risk of intraoperative massive hemorrhage in patients with placenta previa and accreta. This scoring system can potentially reduce the incidence of intraoperative massive bleeding by identifying patients at high risk. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 5 J. Magn. Reson.

Effects of Nurse-Led Support Via WeChat, a Smartphone Application, for Breast Cancer Patients After Surgery: A Quasi-Experimental Study.

Background: Women with breast cancer (BC) commonly experience physical and psychosocial symptoms after surgery. Web- and smartphone-based support can significantly improve women's symptoms and quality of life. Social care applications (apps) are widely used in China, but there are few studies on their effectiveness BC support. This study aimed to examine the effects of nurse-led support on the social care app WeChat® (Tencent Holdings Limited, Shenzhen, China) in BC patients after surgery. Methods: A quasi-experimental study was conducted between June 2015 and August 2015. Sixty patients with BC (30 in the intervention group, 30 in the control group) were enrolled. Subjects in the intervention group participated in a WeChat-based support program (WSP) led by nurses, while subjects in the control group received a follow-up by telephone. Subjects in both groups were evaluated at the time of discharge and at 1, 3, and 6 months of follow-up. Physical well-being status, psychology status, and social support were evaluated. Results: There were no differences between intervention and control patients at baseline. Physical well-being (p < 0.001), anxiety (p < 0.001), depression (p < 0.001), and support from outside of family (p = 0.037) were significantly better in the intervention group than in the control group after 6 months. The intervention group showed that physical well-being (p = 0.036), anxiety (p < 0.001), and depression (p < 0.001) were significantly different from baseline to 6 months of follow-up. Conclusion: WSP assisted with nurse-led support and had physical, psychological, and social benefits for patients after surgery for BC.

The association between antiphospholipid antibodies and late fetal loss: A systematic review and meta-analysis.

INTRODUCTION: Antiphospholipid syndrome is a chronic autoimmune disease with a high prevalence in females. Published data have identified that antiphospholipid antibodies (APLA) of antiphospholipid syndrome are risk factors for poor pregnancy outcomes, such as recurrent spontaneous abortion, intrauterine growth restriction and preeclampsia. However, the association between APLA and late fetal loss is not fully understood and remains controversial. The aim of this study is to identify and analyze the recent publications to better understand the association between APLA and late fetal loss. MATERIAL AND METHODS: The literature was searched on 31 January 2019 using Ovid, Medline, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) to evaluate the association between APLA and late fetal loss, with articles published before January 2019, according to the PRISMA statement. Without imposing regional restrictions, referenced articles were selected. Quality assessment was conducted independently by two reviewers, based on the Newcastle-Ottawa scale. For the meta-analysis, we used odds ratios (random effects model). The between-study heterogeneity was assessed by Q test. Publication bias was assessed by funnel plots. RESULTS: Nineteen studies (with 10 265 cases) were included in the final analysis. The odds ratio (OR) for the late fetal loss with lupus anticoagulant was 5.02 (95% confidence interval [CI] 2.14-7.89). Seven included studies reported that lupus anticoagulant had a statistically significant association with late fetal loss. The results did not show a statistically significant association between anticardiolipin antibodies and late fetal loss. The pooled odds ratio for the association of anticardiolipin antibodies with late fetal loss was 3.47 (95% CI 0.68-6.26). However, we did find the relation between anticardiolipin antibodies and late fetal loss among cohort studies (OR 2.27, 95% CI 1.20-3.44). Anti-beta2 glycoprotein 1 antibodies (ß2GP1) showed a significant association with late fetal loss (OR 3.13, 95% CI 0.75-5.50). CONCLUSIONS: Lupus anticoagulant is strongly associated with late fetal loss in antiphospholipid syndrome patients. However, the association between anticardiolipin antibodies and late fetal loss is inconsistent. There are currently insufficient data to support a significant relation between ß2GP1 and late fetal loss.

The role of propofol on mouse oocyte meiotic maturation and early embryo development.

SummaryPropofol is a intravenous anaesthetic most commonly used in ultrasound oocyte retrieval. We studied if the use of propofol had an effect on mouse oocyte maturation, pregnancy, childbirth and progeny and investigated the correlation between propofol side effects and reproductive performance in mice. There was no statistical difference in mating, pregnancy, childbirth, litter size, the number of stillbirths and survival between each group (P>0.05). Propofol also had no effect on polar body extrusion in oocyte maturation as well as on pronucleus formation and, subsequently, early embryo development (P>0.05). An increased concentration of propofol had no effect on this result, although propofol at more than 0.01 mg/ml reduced polar body extrusion. Different concentrations of propofol had no effect on oocyte culture in vitro, pronucleus formation and early embryo development.

Effect of epilepsy in pregnancy on fetal growth restriction: a systematic review and meta-analysis.

PURPOSE: Epilepsy is one of the most common neurological diseases during pregnancy. However, the influence of epilepsy on fetal growth is not understood. Thus, this study conducted a meta-analysis to determine the influence of epilepsy during pregnancy on fetal growth restriction (FGR). METHODS: BIOSIS, Medline, Embase, and PubMed databases were searched between January 2000 and January 2016. Without imposing language or regional restrictions, referenced articles were selected. RESULTS: Final analysis included 684 citations from 11 studies. Estimated risk of FGR was 1.28-fold higher in epileptic pregnant women than in non-epileptic women [95% confidence interval (95% CI) 1.09-1.50, p < 0.05]. Given the course of previous studies, hierarchical analysis of pregnant women who use antiepileptic drugs (AEDs) was conducted. Results show that FGR rate is significantly increased even if AEDs were taken [odds ratio 1.26, 95% CI 1.13-1.41, p < 0.05]. CONCLUSIONS: Although modest bias cannot be avoided, our meta-analysis indicated that epilepsy participates in fetal development as an unfavorable factor, and AEDs seemed to be useless in decreasing the occurrence rate of FGR.

Relationship between nausea and vomiting and physical activity in patients with lung cancer undergoing first chemotherapy.

Objective: Nausea and vomiting are the distressing and debilitating side effects of chemotherapy. This study explores the relationship between the degree of nausea and vomiting and physical activity in patients with lung cancer during the first chemotherapy cycle. Design: A total of 107 patients with lung cancer who received platinum drugs during chemotherapy in a hospital in Shanghai, China, in 2023 were involved in this study. Data were collected with medical record system and self-reported questionnaires.Questionnaires included the International Physical Activity Questionnaire (IPAQ) and Index of Nausea, Vomiting, and Retching (INVR). IPAQ was used before chemotherapy; INVR was used on the second and sixth day of chemotherapy, followed by the analysis of the correlation between physical activity status and degree of nausea and vomiting during chemotherapy. The influencing factors of nausea and vomiting during chemotherapy in patients with lung cancer were analyzed using logistic regression analysis. Results: More than half of the patients experienced nausea, vomiting or retching related symptoms after chemotherapy, and the proportion of moderate to high physical activity was 50.5%. Univariate analysis showed that the degree of nausea and vomiting was influenced by factors such as age, gender, and history of drinking (P < 0.05). The degree of nausea and vomiting was negatively correlated with physical activity (P < 0.05). The multivariate linear analysis showed that gender, history of drinking, and moderate and high physical activity are contributing factors to nausea and vomiting during chemotherapy (P < 0.05). Conclusion: Moderate and high physical activity before chemotherapy is a protective factor for nausea and vomiting in patients with lung cancer. Physical activity can not only improve the degree of nausea and vomiting in patients with lung cancer but also reduce the incidence in these patients during the first chemotherapy cycle.

Electroacupuncture improves apoptosis of nucleus pulposus cells via the IL-22/JAK2-STAT3 signaling pathway in a rat model of cervical intervertebral disk degeneration.

BACKGROUND: Cervical spondylosis (CS) is a prevalent disorder that can have a major negative impact on quality of life. Traditional conservative treatment has limited efficacy, and electroacupuncture (EA) is a novel treatment option. We investigated the application and molecular mechanism of EA treatment in a rat model of cervical intervertebral disk degeneration (CIDD). METHODS: The CIDD rat model was established, following which rats in the electroacupuncture (EA) group received EA. For overexpression of IL-22 or inhibition of JAK2-STAT3 signaling, the rats were injected intraperitoneally with recombinant IL-22 protein (p-IL-22) or the JAK2-STAT3 (Janus kinase 2-signal transducer and activator of transcription protein 3) inhibitor AG490 after model establishment. Rat nucleus pulposus (NP) cells were isolated and cultured. Cell counting kit-8 and flow cytometry were used to analyze the viability and apoptosis of the NP cells. Expression of IL-22, JAK2 and STAT3 was determined using RT-qPCR. Expression of IL-22/JAK2-STAT3 pathway and apoptosis related proteins was detected by Western blotting (WB). RESULTS: EA protected the NP tissues of CIDD rats by regulating the IL-22/JAK2-STAT3 pathway. Overexpression of IL-22 significantly promoted the expression of tumor necrosis factor (TNF)-α, IL-6, IL-1ß, matrix metalloproteinase (MMP)3 and MMP13 compared with the EA group. WB demonstrated that the expression of IL-22, p-JAK2, p-STAT3, caspase-3 and Bax in NP cells of the EA group was significantly reduced and Bcl-2 elevated compared with the model group. EA regulated cytokines and MMP through activation of IL-22/JAK2-STAT3 signaling in CIDD rat NP cells. CONCLUSION: We demonstrated that EA affected apoptosis by regulating the IL-22/JAK2-STAT3 pathway in NP cells and reducing inflammatory factors in the CIDD rat model. The results extend our knowledge of the mechanisms of action underlying the effects of EA as a potential treatment approach for CS in clinical practice.

Experience in the development of nurses' personal resilience: A meta-synthesis.

AIM: Nurses play roles in hospitals, families, society and other aspects and often face stress sources, such as heavy workload, doctor-patient conflict and medical accidents. Resilience can help the nurses to avoid or reduce various adverse consequences caused by stress sources; however, this phenomenon remains ill-defined and under-researched. The aim of this review was to summarize the experiences of development of nurses' resilience and explore the reasons for the formation of resilience by examining the findings of the existing qualitative studies. DESIGN: The review is a systematic review and meta-synthesis of qualitative studies. DATA SOURCES: PubMed, Cochrane Library, CINAHL, Web of Science, Embase, and Ovid and Chinese databases include the following: Chinese National Knowledge Infrastructure (CNKI), Wanfang Database (CECDB), VIP Database and China Biomedical Database (CBM). REVIEW METHODS: Relevant publications were identified by systematic searches across 11 databases in June 2021. All qualitative and mixed-method studies in English and Chinese that explored the experiences of development of nurses' resilience were included. The qualitative meta-synthesis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Two independent reviewers selected the studies and assessed the quality of each study. Meta-synthesis was performed to integrate the results. RESULTS: A total of nine studies revealed 10 sub-themes and three descriptive themes: being psychologically strong, physical positive coping and adoption of external support. CONCLUSION: Several factors contributed to the development of nurses' resilience, and various supporting strategies in the nursing management and education are helpful to their adaption ability. However, it is necessary to focus on the cultivation of nurses' resilience to improve the quality of clinical nursing. Leaders or organizations are required to establish and sustain multifaceted strategies to improve nurse' resilience through scientific resilience training programmes and improved organizational support.

Generation Z nursing students' online learning experiences during COVID-19 epidemic: A qualitative study.

In early 2022, the coronavirus disease 2019 (COVID-19) continued to spread quickly globally and broke out in some metropolitan areas. To stop the spread of infection, all colleges and universities were shifted to a closed model, and higher education was transformed into online learning (OL). These transitions posed numerous challenges for Generation Z students, especially those in the nursing profession that featured face-to-face practice courses. This study aimed to explore and understand the experiences of OL among Generation Z nursing students during COVID-19 epidemic. This qualitative phenomenological research design applied a purposive sampling approach to enroll 14 Generation Z nursing students from a college. Data were collected and analyzed using in-depth, semi-structured interviews and Colaizzi seven-step method. The analysis demonstrated four themes and eleven subthemes: challenges encountered during OL, advantages perceived during OL, experience of loneliness and stress, and developing resilience during OL. This study concluded that the sudden shift in learning styles presents challenges to Generation Z nursing students. Despite the adversity, the students showed tremendous resilience and endurance. During the pandemic, educators should provide support measures based on the characteristics of Generation Z to improve the effectiveness of OL and respond positively to stress.

Perspectives and experiences of newly registered nurses surrounding the objective structured clinical examination in an obstetrics and gynecology hospital: A qualitative study in Shanghai, China.

OBJECTIVES: Newly registered nurses in China are required to attend two years of standardized training programs after graduation, and an evaluation of the training program's effectiveness is critical. The objective structured clinical examination is a relatively new and objective approach to exploring the effectiveness of training programs and is increasingly being encouraged and used in clinics. However, the perspectives and experiences of newly registered nurses in obstetrics and gynecology regarding the objective structured clinical examination are unclear. Therefore, the objective of this study was to investigate newly registered nurses' perspectives and experiences of the objective structured clinical examination in an obstetrics and gynecology hospital. DESIGN: This qualitative study was conducted using a phenomenological approach. DATA SOURCES: Twenty-four newly registered nurses taking the objective structured clinical examination in a third-level obstetrics and gynecology hospital in Shanghai, China. REVIEW METHODS: Semi-structured face-to-face interviews were conducted between July and August 2021. The Colaizzi seven-step framework was applied for data analysis. RESULTS: Three main themes and six sub-themes emerged: 1) high satisfaction with the objective structured clinical examination; 2) gaining experience and growing as nurses; and 3) high pressure. CONCLUSION: The objective clinical structured examination can be used to assess the competence of newly registered nurses after training in an obstetrics and gynecology hospital. The examination not only enables an objective and comprehensive evaluation of others and self-evaluation but also leads to positive psychological experiences in newly registered nurses. However, interventions are needed to relieve examination pressure and to provide effective support for participants. The objective clinical structured examination can be incorporated into the training assessment system; this study provides a basis for improving training programs and the training of newly registered nurses.

Effects of cerebellar transcranial direct current stimulation on rehabilitation of upper limb motor function after stroke.

Background: The cerebellum is involved in the control and coordination of movements but it remains unclear whether stimulation of the cerebellum could improve the recovery of upper limb motor function. Therefore, this study aimed to explore whether cerebellar transcranial direct current stimulation (tDCS) therapy could promote the recovery of upper limb motor function in patients who suffered a stroke. Methods: In this randomized, double-blind, and sham-controlled prospective study, 77 stroke patients were recruited and randomly assigned to the tDCS group (n = 39) or the control group (n = 38). The patients received anodal (2 mA, 20 min) or sham tDCS therapy for 4 weeks. The primary outcome was the change in the Fugl-Meyer Assessment-Upper Extremity (FMA-UE) score from baseline to the first day after 4 weeks of treatment (T1) and 60 days after 4 weeks of treatment (T2). The secondary outcomes were the FMA-UE response rates assessed at T1 and T2. Adverse events (AEs) related to the tDCS treatment were also recorded. Results: At T1, the mean FMA-UE score increased by 10.7 points [standard error of the mean (SEM) = 1.4] in the tDCS group and by 5.8 points (SEM = 1.3) in the control group (difference between the two groups was 4.9 points, P = 0.013). At T2, the mean FMA-UE score increased by 18.9 points (SEM = 2.1) in the tDCS group and by 12.7 points (SEM = 2.1) in the control group (the difference between the two groups was 6.2 points, P = 0.043). At T1, 26 (70.3%) patients in the tDCS group had a clinically meaningful response to the FMA-UE score compared to 12 (34.3%) patients in the control group (the difference between the two groups was 36.0%, P =0.002). At T2, 33 (89.2%) patients in the tDCS group had a clinically meaningful response to the FMA-UE score compared with 19 (54.3%) patients in the control group (the difference between the two groups was 34.9%, P = 0.001). There was no statistically significant difference in the incidence of adverse events between the two groups. In the subgroup analysis of different hemiplegic sides, the rehabilitation effect of patients with right hemiplegia was better than that of patients with left hemiplegia (P < 0.05); in the age subgroup analysis, different age groups of patients did not show a significant difference in the rehabilitation effect (P > 0.05). Conclusion: Cerebellar tDCS can be used as an effective and safe treatment to promote recovery of upper limb motor function in stroke patients.

Effective Teaching Behaviors of Clinical Nursing Teachers: A Qualitative Meta-Synthesis.

Objectives: To identify, appraise, and synthesize the available evidence exploring the effective teaching behaviors of clinical nursing teachers. Design: The Joanna Briggs Institute (JBI) guidelines were followed, and a meta-synthesis was conducted. Review Methods: Following databases were searched for relevant qualitative studies published in English and reporting primary data analysis, including experiences and perceptions of nursing students: PubMed, EBSCOhost, OVID, etc. Qualitative Assessment and Review Instrument were used to pool the qualitative research findings. Through the repeated reading of the original literature, the similar findings were combined and sorted into new categories, and then summarized into different synthesized themes. Results: A total of nine articles were included. The review process produced 29 subcategories that were aggregated into seven categories. The categories generated three synthesized findings: good teaching literacy, solid professional competence, and harmonious faculty-student relationship. Conclusions: The effective teaching behaviors of clinical nursing teachers are the driving force for the progress and growth of nursing students. In order to improve the effectiveness of clinical nursing teaching, nursing teachers should be fully aware of effective teaching behaviors for nursing students to master nursing theories and skills.

Nurse's Psychological Experiences of Caring for Severe COVID-19 Patients in Intensive Care Units: A Qualitative Meta-Synthesis.

Background: COVID-19 has been listed as an international public health emergency. During the pandemic, the nurses were affected physically and mentally when in contact with and caring for patients infected with COVID-19, especially those in intensive care units (ICUs). Objective: To summarize and evaluate the actual psychological experience of nurses caring for patients with severe pneumonia in the ICUs during the COVID-19 pandemic. Methods: Relevant publications were identified by systematic searches across 11 databases in December 2021. All qualitative and mixed-method studies in English and Chinese from 2019 that explored the experiences of nurses who cared for severe COVID-19 patients in ICUs were included. The qualitative meta-synthesis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Two independent reviewers selected the studies and assessed the quality of each study. Meta-synthesis was performed to integrate the results. Results: A total of 12 studies revealed 9 sub-themes and 3 descriptive themes: physical reactions and psychological changes, the need for support from multiple sources, and increased adaptation and resilience. Conclusion: Nurses who treated severe COVID-19 patients have experienced severe work trials and emotional reactions during the pandemic. They have also developed personally in this process. Managers should develop strategies that address the nurse's needs for external support, reasonably respond to public health emergencies, and improve nursing care outcomes.

Application of machine learning in predicting the risk of postpartum depression: A systematic review.

BACKGROUND: Postpartum depression (PPD) presents a serious health problem among women and their families. Machine learning (ML) is a rapidly advancing field with increasing utility in predicting PPD risk. We aimed to synthesize and evaluate the quality of studies on application of ML techniques in predicting PPD risk. METHODS: We conducted a systematic search of eight databases, identifying English and Chinese studies on ML techniques for predicting PPD risk and ML techniques with performance metrics. Quality of the studies involved was evaluated using the Prediction Model Risk of Bias Assessment Tool. RESULTS: Seventeen studies involving 62 prediction models were included. Supervised learning was the main ML technique employed and the common ML models were support vector machine, random forest and logistic regression. Five studies (30 %) reported both internal and external validation. Two studies involved model translation, but none were tested clinically. All studies showed a high risk of bias, and more than half showed high application risk. LIMITATIONS: Including Chinese articles slightly reduced the reproducibility of the review. Model performance was not quantitatively analyzed owing to inconsistent metrics and the absence of methods for correlation meta-analysis. CONCLUSIONS: Researchers have paid more attention to model development than to validation, and few have focused on improvement and innovation. Models for predicting PPD risk continue to emerge. However, few have achieved the acceptable quality standards. Therefore, ML techniques for successfully predicting PPD risk are yet to be deployed in clinical environments.
