Undergraduate midwifery students' experiential learning of perinatal bereavement care: A qualitative analysis.

BACKGROUND: It is widely acknowledged that midwives are essential in providing care for mothers experiencing perinatal death. However, midwifery students lack the knowledge and skills needed to deal with perinatal death, and. There is limited research on perinatal bereavement care training for midwifery students. AIM: To investigate undergraduate midwifery students' experiential learning of perinatal bereavement care and serve as a reference for future perinatal bereavement care teaching and training. DESIGN: Qualitative descriptive design. SETTING: University in Guangzhou, China. PARTICIPANTS: Undergraduate midwifery students at a university in Guangzhou, China. METHOD: This research was conducted at a university in Guangzhou, China. The participants were recruited using purposeful sampling. Semi-structured, in-depth interviews were conducted with 11 midwifery students who participated in perinatal bereavement care training from May to June 2023. The Colalizzi 7-step data analysis method was used for data analysis. RESULTS: From the data, five themes emerged: 1) immersive experience of perinatal bereavement care, 2) formation of perspectives on perinatal bereavement care, 3) clarification of the service boundaries and internalization of the professional service spirit, 4) emotional impact and coping strategies, and 5)) factors influencing practice optimization. CONCLUSIONS: Experiential learning is an effective teaching strategy. However, participants continued to feel unprepared to provide perinatal bereavement care. Implementing relevant training, disseminating perinatal bereavement care knowledge and skills, and enhancing the ability of midwifery students to manage and cope with the psychological impact of perinatal death are important.

The Associations and Causal Relationships of Ovarian Cancer - Construction of a Prediction Model.

Purpose: To explore the risk and protective factors for developing ovarian cancer and construct a risk prediction model. Methods: Information related to patients diagnosed with ovarian cancer on the electronic medical record data platform of three tertiary hospitals in Guangdong Province from May 2018 to September 2023 was collected as the case group. Patients with non-ovarian cancer who attended the clinic during the same period were included in the control group. Logistic regression analysis was used to screen the independent variables and explore the factors associated with the development of ovarian cancer. An ovarian cancer risk prediction model was constructed using a decision tree C4.5 algorithm. The ROC and calibration curves were plotted, and the model was validated. Results: Logistic regression analysis identified independent risk and protective factors for ovarian cancer. The sample size was divided into training and test sets in a ratio of 7:3 for model construction and validation. The AUC of the training and test sets of the decision tree model were 0.961 (95% CI:0.944-0.978) and 0.902 (95% CI:0.840-0.964), respectively, and the optimal cut-off values and their coordinates were 0.532 (0.091, 0.957), and 0.474 (0.159, 0.842) respectively. The accuracies of the training and test sets were 93.3% and 84.2%, respectively, and their sensitivities were 95.7% and 84.2%, respectively. Conclusion: The constructed ovarian cancer risk prediction model has good predictive ability, which is conducive to improving the efficiency of early warning of ovarian cancer in high-risk groups.

Thrombospondin-1 Regulates Trophoblast Necroptosis via NEDD4-Mediated Ubiquitination of TAK1 in Preeclampsia.

Preeclampsia (PE) is considered as a disease of placental origin. However, the specific mechanism of placental abnormalities remains elusive. This study identified thrombospondin-1 (THBS1) is downregulated in preeclamptic placentae and negatively correlated with blood pressure. Functional studies show that THBS1 knockdown inhibits proliferation, migration, and invasion and increases the cycle arrest and apoptosis rate of HTR8/SVneo cells. Importantly, THBS1 silencing induces necroptosis in HTR8/SVneo cells, accompanied by the release of damage-associated molecular patterns (DAMPs). Necroptosis inhibitors necrostatin-1 and GSK'872 restore the trophoblast survival while pan-caspase inhibitor Z-VAD-FMK has no effect. Mechanistically, the results show that THBS1 interacts with transforming growth factor B-activated kinase 1 (TAK1), which is a central modulator of necroptosis quiescence and affects its stability. Moreover, THBS1 silencing up-regulates the expression of neuronal precursor cell-expressed developmentally down-regulated 4 (NEDD4), which acts as an E3 ligase of TAK1 and catalyzes K48-linked ubiquitination of TAK1 in HTR8/SVneo cells. Besides, THBS1 attenuates PE phenotypes and improves the placental necroptosis in vivo. Taken together, the down-regulation of THBS1 destabilizes TAK1 by activating NEDD4-mediated, K48-linked TAK1 ubiquitination and promotes necroptosis and DAMPs release in trophoblast cells, thus participating in the pathogenesis of PE.

Reasons, experiences and expectations of women with delayed medical care for ectopic pregnancies in Chinese urban edges: a qualitative study.

OBJECTIVE: To explore the experiences of patients with ectopic pregnancies with delayed medical care, with the goals to promote timely access to care, reduce subsequent physical and psychological impacts, and provide recommendations for improved management of ectopic pregnancies. DESIGN: A qualitative study. SETTING: A 1000-bed urban edge hospital located in the suburban area of Guangzhou, China, between December 2022 and February 2023. PARTICIPANTS: 21 patients with delays in seeking medical care for ectopic pregnancy. PRIMARY AND SECONDARY OUTCOME MEASURES: Semistructured, in-depth, face-to-face interviews were conducted to understand the experience and expectations of these women. RESULTS: Three main themes emerged, including delaying medical care, physical and psychological experiences, and expectations of their healthcare providers. Each of these main themes had several subthemes. The central theme of reasons for delaying medical care had five subthemes, including lack of knowledge on early symptoms of ectopic pregnancy, family dynamics and circumstances, traditional fertility ideology and intentions, avoidance of medical treatment behaviour, and medical delays. The main theme of physical and psychological experiences had two subthemes, including learnings from the experiences and negative impacts of the experiences. The main theme of expectations of their healthcare providers included three subthemes that were reducing the length of outpatient examinations and waiting times, increasing public understanding of early symptoms of ectopic pregnancy and increasing male awareness of safe contraceptive methods. CONCLUSIONS: A lack of knowledge about the early symptoms of ectopic pregnancy was the main reason for delays in seeking medical care and had a dual impact on patients' physical and mental health, affecting their recovery and future healthcare. A collective effort from patients, families, healthcare providers and medical institutions is required for better medical education, family support, specialised professional training and local fertility policy to decrease the incidence of delayed medical care and achieve satisfactory pregnancy outcomes.

Effects of parenting style on depressive symptoms, anxiety symptoms, and their comorbidity during the COVID-19 pandemic lockdown among 3117 Chinese junior high school students.

INTRODUCTION: Depressive symptoms, anxiety symptoms, and comorbidity increased in junior high school students due to the outbreak of COVID-19. The objective of this study was to measure the impacts of parenting style on depressive symptoms, anxiety symptoms, and their comorbidity in Chinese junior high school students during the COVID-19 pandemic lockdown period. METHODS: An online survey was conducted in June 2020 among 3117 junior high school students from Shandong Province, China. The Egna Minnen av Barndoms Uppfostran scale was used to measure parenting styles. The 9-item Patient Health Questionnaire scale and the 7-item Generalized Anxiety Disorder scale were used to measure depressive symptoms and anxiety symptoms, respectively. Multinomial logistic regression was conducted with SPSS 25.0 Version. RESULTS: 3117 junior school students enrolled in this study. The prevalence of depressive symptoms only, anxiety symptoms only, and comorbidity among junior high school students was 11.55 %, 5.29 %, and 22.97 %. Paternal over-protection was a risk factor not only for depressive symptoms only (OR = 1.075, 95 % CI = 1.020-1.134) but for anxiety symptoms only (OR = 1.090, 95 % CI = 1.016-1.170) and comorbidity (OR = 1.098, 95 % CI = 1.050-1.148). Paternal over-interference was a protective factor for depressive symptoms only (OR = 0.947, 95 % CI = 0.908-0.987) and comorbidity (OR = 0.953, 95 % CI = 0.921-0.986). However, maternal over-interference and over-protection were risk factors for depressive symptoms only (OR = 1.039, 95 % CI = 1.011-1.068). LIMITATIONS: This was a cross-sectional study and the causal inferences could not be conducted. CONCLUSIONS: Junior high school students with poorer family environmental factors were more likely to suffer from the comorbidity of anxiety symptoms and depressive symptoms during the COVID-19 pandemic lockdown. Decision-makers from the government, educational, and healthcare institutions should pay more attention to junior high school students at higher risk of mental disorders due to poor parenting styles. We should discuss family interventions in the future to prevent mental disorders in junior high school students.

Prevalence of workplace violence in Chinese obstetric nurses under the new situation and its correlation with violence prevention knowledge-attitude-practice and climate perception: a cross-sectional study.

BACKGROUND: Workplace violence severely impacts individual nurses. With the three-child opening policy of China and the impact of the COVID-19 epidemic in the recently years, obstetric nurses face the double attack of heavy workload and staffing shortage. This study aimed to evaluate the current situation of workplace violence among Chinese obstetric nurses under the new situation, assess the level of violence prevention knowledge-attitude-practice and climate perception in Chinese obstetric nurses and explore the correlation between workplace violence and the level of violence prevention knowledge-attitude-practice and climate perception. METHODS: A cross-sectional survey on the workplace violence for Chinese obstetric nurses was conducted from August to February 2023. All the questionnaires came from 10 provinces and 3 autonomous regions in China. The basic characteristics of obstetric nurse's workplace violence, workplace violence prevention knowledge-attitude-practice scale and workplace violence climate perception scale were collected. RESULTS: Totally, 522 Chinese obstetric nurses were included. 55.0% of obstetric nurses (287) had experienced workplace violence in the past 12 months, including verbal assault (40.4%), physical assault (34.1%), and sexual assault (31.0%). The overall level of obstetric nurses' workplace violence prevention knowledge-attitude-practice and climate perception of workplace violence was low. Multiple linear regression analysis showed that the violence prevention knowledge dimension significantly influenced obstetric nurses' workplace violence (B = -0.278, P < .001), attitude dimension (B = -0.241, P < .001), behavior dimension (B = -0.216, P < .001) and the violence climate perception's organizational management (B = -0.177, P < .001), organizational training (B = -0.175, P < .001), organizational support (B = -0.143, p < .001) and the violence handling (B = -0.165, P < .001). CONCLUSION: The incidence of workplace violence among obstetric nurses in the new situation is high. However, the overall violence prevention knowledge-attitude-practice and climate perception levels are low. Therefore, nursing managers should take targeted measures according to the relevant influencing factors and the characteristics of obstetrics to improve the level of obstetric nurses' violence prevention knowledge-attitude-practice and climate perception to reduce workplace violence among obstetric nurses.

Effects of obstetric critical care simulation training on core competency and learning experience of midwives: A pilot quasi-experimental study.

AIM: This study aimed to investigate the effects of maternal critical care simulation training on the core competency and satisfaction of midwives in China. BACKGROUND: Midwives play an important role during the peripartum period. Simulation-based training could be an effective tool in improving the core competency of midwives when managing critical obstetric illnesses. DESIGN: A pilot pre- and post-course, quasi-experimental study in China. METHOD: In July 2022, 82 midwives completed a 2-day obstetric critical care simulation training and survey. Core competency was evaluated by a comprehensive score system, including response ability, communication ability, site control ability, critical thinking ability, team cooperation ability, forward-thinking ability, midwifery specialty ability, and error correction ability. We used the Simulation Effectiveness Tool-Modified (SET-M) to evaluate the learning experience and satisfaction. Descriptive analysis, McNemar χ2 test, and subject content analysis were used for data analysis. RESULTS: After the training, the core competency scores showed significant improvements in the case scenarios simulating shoulder dystocia, amniotic fluid embolism, and eclampsia (P < 0.05) but not postpartum hemorrhage (P > 0.05). The scores evaluated by the SET-M were all above 2.5 points. Some midwives preferred extended course duration, expanded course materials, and more active involvement in the simulation exercises. The midwives were generally highly satisfied with the training, but some expressed certain negative emotions, such as anxiety and nervousness. CONCLUSION: The high quality of scientifically constructed and implemented obstetric critical care simulation training courses could improve the core competency and satisfaction of midwives. Appropriate preparation and professional simulation teachers are required to reduce negative emotions and improve learning outcomes and experience.

A mental health survey among young front-line clinicians in high-risk areas during the COVID-19 sporadic epidemic in China.

Background: The sporadic coronavirus disease (COVID-19) epidemic has placed enormous psychological stress on people, especially clinicians. The objective of this study was to examine depression, anxiety, quality of life (QOL), and related social psychological factors among young front-line clinicians in high-risk areas during the COVID-19 sporadic epidemic in China and to provide a reference for formulating reasonable countermeasures. Methods: In this cross-sectional study, demographic information, COVID-19-related questions, anxiety (Generalized Anxiety Disorder-7, GAD-7), depression (Patient Health Questionnaire-9, PHQ-9), insomnia (Insomnia Severity Index, ISI), stress (Perceived Stress Scale-10, PSS-10), and QOL (World Health Organization Quality of Life-brief version, WHOQOL-BREF) were collected. Binary logistic regression analysis was used to test the relationships between anxiety and/or depression and other related problems. Multiple linear regression analysis was used to test the relationships among factors influencing QOL. Results: A total of 146 young front-line clinicians were included. The prevalence rates of depression, anxiety, and anxiety-depression comorbidity were 37.7% (95% CI = 29.7-45.6%), 26.0% (95% CI = 18.8-33.2%), and 24.0% (95% CI = 17.0-31.0%), respectively. Severe stress (OR = 1.258, 95% CI = 1.098-1.442, P < 0.01) and insomnia (OR = 1.282, 95% CI = 1.135-1.447, P < 0.01) were positively correlated with depression. Severe stress (OR = 1.487, 95% CI = 1.213-1.823, P < 0.01) and insomnia (OR = 1.131, 95% CI = 1.003-1.274, P < 0.05) were positively correlated with anxiety. Severe stress (OR = 1.532, 95% CI = 1.228-1.912, P < 0.01) was positively correlated with anxiety-depression comorbidity. However, insomnia (OR = 1.081, 95% CI = 0.963-1.214, P > 0.05) was not correlated with anxiety-depression comorbidity. The belief that the vaccine will stop the COVID-19 pandemic (OR = 0.099, 95% CI = 0.014-0.715, P < 0.05) was negatively correlated with anxiety and anxiety-depression comorbidity (OR = 0.101, 95% CI = 0.014-0.744, P < 0.05). Severe stress (B = -0.068, 95% CI = -0.129 to -0.007, P < 0.05) and insomnia (B = -0.127, 95% CI = -0.188 to -0.067, P < 0.01) were negatively correlated with QOL. The belief that the vaccine could provide protection (B = 1.442, 95% CI = 0.253-2.631, P < 0.05) was positively correlated with QOL. Conclusions: The prevalence of depression, anxiety, and even anxiety-depression comorbidity was high among young front-line clinicians in high-risk areas during the COVID-19 sporadic epidemic in China. Various biological and psychological factors as well as COVID-19-related factors were associated with mental health issues and QOL. Psychological intervention should evaluate these related factors and formulate measures for these high-risk groups.

Gender-Specific Related Factors for Suicidal Ideation During COVID-19 Pandemic Lockdown Among 5,175 Chinese Adolescents.

Background: Suicide was an urgent issue during the pandemic period in adolescents. However, few studies were focused on suicide during the coronavirus disease 2019 (COVID-19) pandemic lockdown. Methods: An online survey was conducted among 5,175 Chinese adolescents from June 9th to 29th in 2020 to investigate the prevalence of suicidal ideation (SI) during COVID-19 pandemic lockdown. A gender-specific stepwise logistic regression model was used. All analyses were performed with STATA 15.0. Results: About 3% of the participants had reported having SI during the COVID-19 pandemic lockdown period. The prevalence of female SI (3.64%, 95% CI: 2.97-4.45%) was higher than that of males (2.39%, 95% CI: 1.88-3.05%) (χ2 = 6.87, p = 0.009). Quarreling with parents [odds ratio (OR) = 9.73, 95% CI: 5.38-17.59], insomnia (OR = 5.28, 95% CI: 2.81-9.93), previous suicide attempt history (OR = 3.68, 95% CI: 1.69-8.03), previous SI history (OR = 2.81, 95% CI: 1.30-6.06), and feeling depressed during pandemic lockdown (OR = 2.26, 95% CI: 1.22-4.18) were positively associated with the males' SI. However, having emptiness inside (OR = 4.39, 95% CI: 2.19-8.79), quarreling with parents (OR = 3.72, 95% CI: 2.16-6.41), insomnia (OR = 3.28, 95% CI: 1.85-5.80), feeling anxious (OR = 2.62, 95% CI: 1.46-4.70), and longing for father's emotional warmth (OR = 0.38, 0.20-0.72) were associated mostly with females' SI. Conclusions: Female adolescents, who felt emptiness from their families and their fathers' emotional warmth, were at much higher risk of having SI during COVID-19 lockdown. We must specify a suicide prevention policy and interventions for adolescents in the pandemic crisis based on gender gaps.

Lack of neural load modulation explains attention and working memory deficits in first-episode schizophrenia.

OBJECTIVE: Although working memory (WM) deficits are well-recognized core features of schizophrenia, the underlying pathophysiological substrates of impairment in early psychosis before medication remain unclear. One possibility is that deficits in selective attention contribute to WM impairment. METHODS: EEG was acquired from 25 first-episode drug-naive schizophrenia patients and 26 matched controls while they performed a WM task. RESULTS: Compared with controls, schizophrenia patients showed a deficit in WM capacity in both behavioral and electrophysiological measures. Notably, the increased parieto-occipital pre-encoding stimulus alpha power in patients with schizophrenia predicted their subsequent reduced N2pc and symptom severity, whereas this relationship was absent in controls. Moreover, lacking load effect in neural activities predicted the serious impairment in behavior for schizophrenia. CONCLUSIONS: This pilot study provides preliminary evidence that the lack of load effect in neural activities may serve as potential underlying mechanisms for the impaired selective attention and WM capacity in schizophrenia. Our results emphasize the importance of pre-encoding stimulus alpha power in first-episode drug-naive schizophrenia. SIGNIFICANCE: These findings provide a neurophysiological correlate for the subjective reports of working memory deficits in schizophrenia and indicate the potential effective targets for clinical intervention.

Assessment of the relationships between genetic determinants of thyroid functions and bipolar disorder: A mendelian randomization study.

BACKGROUND: Thyroid functions (TFs) have been implicated in the initiation and propagation of psychiatric disorders. Observational studies have shown associations of TFs with psychiatric disorders. However, the relationship between TFs and psychiatric diseases were still unclear. METHODS: Genetic instruments for 6 TF-realted indexes, including free thyroxine (FT4), triiodothyronine (FT3):FT4 ratio, thyrotropin (TSH), thyroid peroxidase antibodies (TPOAb) concentration, hypothyroidism, and hyperthyroidism, were obtained from several genome-wide association studies (GWASs). Their associations with BD were evaluated using Psychiatric Genomics Consortium (PGC) datasets (41,917 cases and 371,549 controls). All GWAS summary statitics were from European ancestry. Mendelian randomization (MR) estimates from each genetic instrument were combined using inverse variance weighted (IVW) meta-analysis, with complementary methods (eg, weighted median and MR Egger). We also multiple sensitivity analyses to examine horizontal pleiotropy and heterogeneity. RESULTS: Genetically predicted level of FT4 was significantly associated with BD (odds ratio (OR)=0.89, 95% confidence interval (CI): 0.83-0.95; P=4.65 × 10-3), survived after the Bonferroni correction (P<0.05/6=0.008). Consistent directional effects for all sensitivity analyses were observed in the weighted median and MR Egger methods. Furthermore, our sensitive test suggested no significant horizontal pleiotropy (intercept=-0.01, P=0.12) and no notable heterogeneity (Q = 29.9; P=0.09). However, other TF indexes (FT3:FT4 ratio [OR=1.24, P=0.10], TSH [OR=1.01, P=0.61], TPOAb concentration [OR=1.20, P=0.54], hypothyroidism [OR=1.00, P=0.91], and hyperthyroidism [OR=0.99, P=0.57]) were not associated with BD. CONCLUSIONS: Our results provide further evidence that higher FT4 level is associated with a reduced risk of BD, and suggest the importance of FT4 level in BD risk assessment and potential therapeutic targets development.

Associations between borderline personality disorder features and the risk of first onset major depressive disorder: Findings from a 2-year longitudinal study in a sample of first-year university students in China.

BACKGROUND: The objective of this study was to estimate the associations between specific BPD features on the risk of first onset MDD over 2 years and to investigate the roles of sex, baseline depression and anxiety in the associations. METHODS: A longitudinal study of Chinese first-year university students aged between 15 and 24 years and who did not have a lifetime MDD (n = 7,627). Random effect logistic regression modeling was used to estimate the associations between specific BPD features, the number of BPD features, and the risk of MDD. RESULTS: The feeling of emptiness (OR = 2.14, 95% CI: 1.57, 2.92), paranoid/ dissociation (OR = 2.01, 95% CI: 1.43, 2.82), affective instability (OR = 1.71, 95% CI: 1.22, 2.39) conferred significant risk of MDD. Baseline depression and anxiety interacted with unstable relationship, identity disturbance and paranoid/disassociation in relation to the risk of MDD. A higher number of BPD features is associated with an increased risk of MDD. LIMITATIONS: Data collection relied on self-report. Thus, recall and reporting biases are possible. Due to the pandemic public health restrictions, we had to change the method of data collection at second annual assessment, which resulted in a lower response rate (66.5%). CONCLUSIONS: Mental health professionals should pay attention to the presence of BPD features in youth and young adults, as they are at high risk of developing a MDD in a short time period, and the risk increases with the number of BDP features.

Highly efficient BiVO4single-crystal nanosheets with dual modification: phosphorus doping and selective Ag modification.

BiVO4, a visible-light response photocatalyst, has shown tremendous potential because of abundant raw material sources, good stability and low cost. There exist some limitations for further applicaitions due to poor capability to separate electron-hole pairs. In fact, a single-component modification strategy is barely adequate to obtain highly efficient photocatalytic performance. In this work, P substituted some of the V atoms from VO4oxoanions, namely P was doped into the V sites in the host lattice of BiVO4by a hydrothermal route. Meanwhile, Ag as an attractive and efficient electron-cocatalyst was selectively modified on the (010) facet of BiVO4nanosheets via facile photo-deposition. As a result, the obtained dually modified BiVO4sheets exhibited enhanced photocatalytic degradation property of methylene blue (MB). In detail, photocatalytic rate constant (k) was 2.285 min-1g-1, which was 2.78 times higher than pristine BiVO4nanosheets. Actually, P-doping favored the formation of O vacancies, led to more charge carriers, and facilitated photocatalytic reaction. On the other hand, metallic Ag loaded on (010) facet effectively transferred photogenerated electrons, which consequently helped electron-hole pairs separation. The present work may enlighten new thoughts for smart design and controllable synthesis of highly efficient photocatalytic materials.

Covariation between spontaneous neural activity in the insula and affective temperaments is related to sleep disturbance in individuals with major depressive disorder.

BACKGROUND: Affective temperaments have been considered antecedents of major depressive disorder (MDD). However, little is known about how the covariation between alterations in brain activity and distinct affective temperaments work collaboratively to contribute to MDD. Here, we focus on the insular cortex, a critical hub for the integration of subjective feelings, emotions, and motivations, to examine the neural correlates of affective temperaments and their relationship to depressive symptom dimensions. METHODS: Twenty-nine medication-free patients with MDD and 58 healthy controls underwent magnetic resonance imaging scanning and completed the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS). Patients also received assessments of the Hamilton Depression Rating Scale (HDRS). We used multivariate analyses of partial least squares regression and partial correlation analyses to explore the associations among the insular activity, affective temperaments, and depressive symptom dimensions. RESULTS: A profile (linear combination) of increased fractional amplitude of low-frequency fluctuations (fALFF) of the anterior insular subregions (left dorsal agranular-dysgranular insula and right ventral agranuar insula) was positively associated with an affective-temperament (depressive, irritable, anxious, and less hyperthymic) profile. The covariation between the insula-fALFF profile and the affective-temperament profile was significantly correlated with the sleep disturbance dimension (especially the middle and late insomnia scores) in the medication-free MDD patients. CONCLUSIONS: The resting-state spontaneous activity of the anterior insula and affective temperaments collaboratively contribute to sleep disturbances in medication-free MDD patients. The approach used in this study provides a practical way to explore the relationship of multivariate measures in investigating the etiology of mental disorders.

Promoting healthy lifestyle considerations during pregnancy in Midwifery clinics in China: a best practice implementation project.

OBJECTIVES: The aim of this project was to initiate and promote formal and individualized evidence-based education on healthy lifestyle choices during pregnancy for pregnant women. INTRODUCTION: Evidence suggests that lifestyle choices during pregnancy can have a profound influence on many pregnancy complications and chronic diseases such as preterm birth, diabetes, obesity, fetal growth restriction, breast cancer and hypertensive diseases in both pregnant women and their babies. It is widely accepted that formal, individualized, hospital-directed education about lifestyle choices during pregnancy should commence as early as the first consultation between pregnant women and maternal healthcare workers. METHODS: The methods of this project were audit and feedback. The approach to data collection used the Joanna Briggs Institute (JBI) Practical Application of Clinical Evidence System and implementation planning utilized the Getting Research into Practice component. A baseline audit of 50 observations of midwife-led education on prenatal lifestyle were conducted and measured against seven best practice audit criteria. Targeted strategies were then implemented to improve compliance to best practice. A follow-up audit was conducted over a 6-month period from June 2019 to November 2019. RESULTS: The baseline audit revealed significant deficits between current prenatal education practice and recommended best practice. Zero percent compliance was observed in six out of seven audit criteria, indicating that education provided did not conform to best practice. Total compliance (100%) was observed for one audit criterion at baseline, assessing pregnant women being offered an opportunity to discuss and ask questions regarding the education session or information they had received. Three barriers that prevented midwives from achieving compliance with best practice were identified, and a bundled education strategy was implemented. A follow-up audit indicated 100% compliance of all audit criteria. CONCLUSION: Results demonstrated that formal, individualized, midwife-led prenatal education and provision of relevant evidence-based resources had an immediate positive effect. The project helped to transform care givers' attitudes toward education regarding lifestyle during pregnancy from a passive routine 'must do' task to an active process with focus on healthy lifestyle and engagement of pregnant women. Future strategies such as support from hospital management and social media are planned in conjunction with follow-up clinical audits to ensure sustainability.

Risk factors for anxiety and depression in Chinese patients undergoing surgery for endometrial cancer.

This study analyzed risk factors for anxiety and depression in 714 patients who received surgery for endometrial cancer. Our data indicate that the incidence of postoperative anxiety and depression in 714 patients with endometrial cancer was 15.55% and 32.77%, respectively. Univariate and logistic regression analysis showed postoperative pain (odds ratio (OR) = 3.166, P = 0.000) and combined liver disease (OR = 2.318, P = 0.001) were independent risk factors for postoperative anxiety. Additionally, CD4+/CD8+ (OR = 0.513, P = 0.042) and natural killer (NK) cell ratios (OR = 0.692, P = 0.021) were independent protective factors for postoperative anxiety. As for depression, low literacy (OR = 1.943, P = 0.042), postoperative pain (OR = 2.671, P = 0.001), high clinical stage (OR = 3.469, P = 0.009), and combined liver disease (OR = 4.865, P = 0.000) were independent risk factors for postoperative depression. CD4+/CD8+ (OR = 0.628, P = 0.002) and NK cell ratio (OR = 0.710, P = 0.013) were independent protective factors for postoperative depression. In conclusion, patients with endometrial cancer have a higher incidence of postoperative anxiety and depression where postoperative pain, liver disease, and decreased immune function are risk factors for both anxiety and depression in these patients.

The association of endocannabinoid receptor genes (CNR1 and CNR2) polymorphisms with depression: A meta-analysis.

Studies investigating the association between gene variants and depression susceptibility found inconsistent data. The present study aimed to clarify whether CNR1rs1049353, CNR1 AAT triplet repeat, and CNR2rs2501432 polymorphisms confer higher risk for depressive disorder.Literature from PubMed, Medline, Embase, Scopus, Cochrance Library, and Wanfang databases was searched (up to August 20, 2018). Seven case-control studies with various comorbidities were eligible. We targeted CNR single-nucleotide polymorphisms (SNPs) that have been reported by 2 or more studies to be involved in the current meta-analysis, resulting in a final list of 3 SNPs: CNR1rs1049353, CNR1 AAT triplet repeat polymorphism, and CNR2rs2501432. Odds ratios (ORs) and 95% confidence intervals (CIs) for allele and homozygote comparisons, dominant and recessive models, and triplet repeat polymorphism ((AAT)n≥5, ≥5 vs (AAT)n<5, <5 or <5, ≥5) were assessed using a random effect model as measures of association. Heterogeneity among included studies was analyzed using sensitivity test. Publication bias was also explored by Egger and rank correlation test.overall, no significant association was found between depression and CNR1rs1049353 (G vs A: OR [95% CI] = 1.09 [0.61-1.95]; GG vs AA: 1.29 [0.73-2.26]; GG vs GA+AA: 1.10 [0.57-2.10]; GG+GA vs AA: 1.25 [0.72-2.18]; and AAT triplet repeat polymorphism ((AAT)n≥5, ≥5 vs (AAT)n<5, <5 or <5, ≥5): 1.92 [0.59-6.27]. In contrast, a significant association between CNR2rs2501432 and depression was detected, and the ORs and 95% CIs are as follows: allele contrast (OR = 1.39, 95% CI = [1.12-1.72], P = .003); homozygous (OR = 2.19, 95% CI = [1.34-3.59], P = .002); dominant (OR = 1.93,95% CI = [1.23-3.04], P = .005); and recessive (OR = 1.41, 95% CI = [1.04-1.92], P = .03).This meta-analysis revealed that CNR1rs1049353 or AAT triplet repeat polymorphism had no association with susceptibility to depression, while CNR2rs2501432 polymorphism was a remarkable mark for depression patients.

Network functional connectivity analysis in individuals at ultrahigh risk for psychosis and patients with schizophrenia.

Schizophrenia is a severe mental disorder, and the onset of which is preceded by a stage of ultrahigh risk (UHR) for developing psychosis. Therefore, analyzing individuals with UHR is essential for identifying predictive biomarkers for the onset of schizophrenia. The current study aimed to identify such biomarkers based on a voxelwise whole-brain functional degree centrality (FDC) analysis. Conjunction analysis showed that, compared with healthy controls, both UHR subjects and patients with schizophrenia showed significantly increased FDC at the medial prefrontal cortex (MPFC) and significantly decreased FDC at the right fusiform gyrus (FG). The subsequent partial correlation analysis showed significant correlations between the disorganization symptoms and FDCs at the MPFC and the right FG for both UHR subjects and patients with schizophrenia. These findings suggest that FDC within the MPFC and the right FG could be candidate biomarkers for the onset of schizophrenia.

The effects of CACNA1C gene polymorphism on prefrontal cortex in both schizophrenia patients and healthy controls.

CACNA1C gene polymorphism rs2007044 has been reported to be associated with schizophrenia, but its underlying brain mechanism is not clear. First, we conducted an exploratory functional magnetic resonance imaging (fMRI) study using an N-BACK task and a Stroop task in 194 subjects (55 schizophrenia patients and 139 healthy controls). Our whole brain analysis found that the risk allele was associated with reduced activation of the left inferior frontal gyrus (IFG) during the Stroop task (cluster size = 390 voxels, P < 0.05 TFCE-FWE corrected; peak MNI coordinates: x = -57, y = -6, z = 30). We also conducted a functional near-infrared spectroscopy (fNIRS) study using the same Stroop task in an independent sample of 126 healthy controls to validate the fMRI finding. Our repeated-measures ANCOVA on the six channels (20, 27, 33, 34, 40 and 46) within the left IFG also found significant result. The polymorphism rs2007044 showed significant effect on the oxy-Hb data (F = 5.072, P = 0.026) and showed significant interaction effect with channels on the deoxy-Hb data (F = 2.841, P = 0.015). Taken together, results of this study suggested that rs2007044 could affect the activation of the left IFG, which was a possible brain mechanism underlying the association between CACNA1C gene polymorphism and schizophrenia.

Polymorphism in schizophrenia risk gene MIR137 is associated with the posterior cingulate Cortex's activation and functional and structural connectivity in healthy controls.

MIR137 gene has been repeatedly reported as a schizophrenia risk gene in genome-wide association studies (GWAS). A polymorphism (rs1625579) at the MIR137 gene has been associated with both neural activation and behavioral performance during a working memory task. This study examined MIR137's associations with task-related (N-back working memory) fMRI, resting state fMRI, and diffusion tensor images (DTI) data in 177 healthy adults. We found less deactivation of the PCC in risk allele homozygotes (TT) as compared to the GT heterozygotes (cluster size = 630 voxels, cluster level PFWE < 0.001) during the N-back task, which replicated previous findings. Using the identified cluster within the PCC as the seed, we further found decreased functional connectivity between the PCC and the anterior cingulate cortex and its adjacent medial prefrontal cortex (ACC/MPFC) in risk allele homozygotes during both resting state (cluster size = 427 voxels, cluster level PFWE = 0.001) and the N-back task (cluster size = 73 voxels, cluster level PFWE = 0.05). Finally, an analysis of our DTI data showed decreased white matter integrity of the posterior cingulum in risk allele homozygotes (cluster size = 214 voxels, cluster level PFWE = 0.03). Taken together, rs1625579 seems to play an important role in both functional and structural connectivity between the PCC and the ACC/MPFC, which may serve as the brain mechanisms for the link between rs1625579 and schizophrenia.
