Both •OH addition on benzene ring and H-abstraction reactions were simulated to identify the possible pathways for the degradation. On the basis of activation free energy analysis, degradation pathways initiating with both •OH addition and H abstraction were determined to be feasible. The ortho-C of benzene ring was the most favourable site for •OH addition, while H atom of phenolic hydroxyl group was more susceptible (or more reactive) for H-atom abstraction route.Short-chain chlorinated paraffins (SCCPs) are listed in Annex A (elimination) of the Stockholm Convention on persistent organic pollutants, and products containing SCCPs require detoxification. In the present study, the metal sodium (Na) dispersion method was applied to a wax sample containing SCCPs (58%, C10-C13 and Cl5-Cl9) to assess the dechlorination effect. Effective dechlorination of SCCPs was confirmed using 2-L and 20-L reaction systems. The initial concentrations of the wax (5, 10, 20, 30%), reaction time (10, 30, 60, 120, 180 min), and the ratios of the amount of Na dispersion and the initial amount of the wax containing SCCPs (Na/wax ratios; 3.9, 4.4, 5.2) were tested. The destruction efficiency of SCCPs was over 99.999% after 10 min of reaction at 90 °C under several conditions. The initial concentrations of the wax and the Na/wax ratios did not affect the results. The ultralow SCCP contents in exhaust gas from the reaction tank demonstrated a destruction removal efficiency of over 99.999999%. Trace levels of polychlorinated dibenzo-p-dioxins and furans, dioxin-like polychlorinated biphenyls, hexachlorobenzene, and pentachlorobenzene in the wax sample and treated materials (oil, water, and gas) met various regulatory values or exhibited the same levels as the environmental background. After dechlorination of the SCCPs, the main reaction products in the reaction liquid and final oil phase were identified as aliphatic compounds. The metal Na dispersion method was found to be an effective and decontaminated destruction technique for application to SCCPs in liquid-like samples with no formation of hazardous organic byproducts.

Prenatal depression affects 20.7 percent of women worldwide, which was associated with preterm birth, low birth weight and Apgar score, as well as cognitive, emotional and behavioral development disorders. We conducted a systematic review and meta-analysis to retrieve the latest and best evidence about music, massage, yoga and exercise in the prevention and treatment of prenatal depression, and to preliminarily compare the four methods to explore the most effective means. We also compared different types of yoga and music, in order to find the mosteffective type of intervention.

A comprehensive literature search was carried out through six databases on randomized controlled trials (RCTs). Effects were summarized by a random effects model using mean differences with 95% confidence intervals. Evidence quality was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria.

This research found low to very low evidence that yoga, exercise, music and massage could reduce antenatal depression. Among them, music may be the most effective intervention, and integrated yoga other than simple yoga would improve prenatal depression. The effect of Chinese Medicine Five Element Music may be better than ordinary music.

Major depressive disorder (MDD) is heterogeneous, but official diagnostic classifications and widely used rating scales are based on the premise that MDD is a single disorder and that symptoms are equally important to assess severity. Also, patients and clinicians frequently diverge in how they evaluate MDD severity. In order to better understand the differences between MDD scales used by clinicians and patients in the context of MDD heterogeneity, we performed a network analysis from an approach that focuses on the interaction of symptoms rather than total score.

The Hamilton Depression Rating Scale (HDRS) and the Beck Depression Inventory with 21 items (BDI) scored by the clinician or patient, respectively, were used to estimate the networks based on 794 MDD patients. The networks were estimated using software R 4.0.2 and Graphical Lasso, identifying communities of symptoms by the clique percolation method, and the mixed graphical models were used to evaluate the explained variance of each symptom.

It is not clear which method is more cost-effective To initially provide all depressed patients with combination therapy (COMB; i.e. cognitive behavioural therapy plus pharmacotherapy), followed by antidepressant treatment (AD) for those still in depression; or, to first provide AD for all patients, followed by COMB for non-remission patients. The aim is to investigate whether a COMB-first strategy would be more cost-effective than an AD-first strategy, in treating depression.

A Markov model was developed to perform the analysis. The primary outcome was the incremental cost-effectiveness ratio (ICER) per quality-adjusted life year (QALY) at 104 weeks. Probabilistic sensitivity analysis and scenario analysis were performed, to investigate the uncertainty associated with the clinical parameters and the impact of CBT's cost on the results, respectively.

The ICER per QALY at 104 week, was JPY 591,822 (USD 5,725) for moderate depression and JPY 499,487 (USD 4,832) for severe one. The scenario analysis revealed the ICER became JPY 1,147,518 (USD 11,101) for moderate and JPY 968,484 (USD 9,369) for severe when the CBT cost was set as JPY 14,400 (USD 139)(i.e. GBP 96 the unit cost of CBT in UK), which is well below the threshold recommended by NICE (i.e. GBP 20,000-30,000).

This is a model-based analysis which was conducted from the health insurance perspective. Then, the analysis from the societal perspective would generate different results.

The results suggest that a COMB-first strategy would be more cost effective than an AD-first strategy.

The brain-gut-microbiota axis plays a crucial role in the bidirectional interactions between the brain and the gut. Soluble epoxide hydrolase (coded by the Ephx2 gene) plays an important role in inflammation, which has been implicated in stress-related depression. Ephx2 knock-out (KO) mice exposed to chronic social defeat stress (CSDS) did not show depression-like behaviors, indicating stress resilience. Here we examined whether the brain-gut-microbiota axis influences the resilience in Ephx2 KO mice.

Effects of fecal microbiota transplantation (FMT) from CSDS-susceptible (or control) mice in wild-type (WT) mice and Ephx2 KO mice treated with an antibiotic cocktail (ABX) were investigated. Behavioral, biochemical tests and 16S ribosome RNA analysis were performed.

FMT from CSDS-susceptible mice produced anhedonia-like behavior in ABX-treated WT and Ephx2 KO mice. The 16S ribosome RNA analysis showed that Faecalibaculum rodentium (F. rodentium) may be responsible for the observed anhedonia-like behavior following FMT from CSDS-susceptible mice. Ingestion of F. rodentium for 14 days produced depression- and anhedonia-like behaviors, higher blood levels of interleukin-6, and reduced expression of synaptic proteins in the prefrontal cortex of ABX-treated Ephx2 KO mice. Furthermore, subdiaphragmatic vagotomy blocked the development of these behavioral abnormalities after ingestion of F. rodentium.

Detailed mechanisms are unclear.

These findings suggest that F. rodentium might contribute to the conversion of resilient Ephx2 KO mice into KO mice with depression-like phenotypes. The brain-gut-microbiota axis via the subdiaphragmatic vagus nerve plays a crucial role in susceptibility and resilience to stress.

Glucose metabolism is related to depression, but the relationship between blood glucose and suicide attempts in patients with major depressive disorder (MDD) remains unclear. This large-scale sample explores the relationship between suicide attempts and fasting blood glucose, in addition to sex differences in first-episode and drug naive (FEDN) MDD patients.

1718 FEDN MDD patients diagnosed for the first time were recruited, and their demographic data, clinical data, and blood glucose indicators were collected. 17-item Hamilton Depression Rating Scale (HAMD), 14-item Hamilton Anxiety Rating Scale (HAMA), and positive subscale of the Positive and Negative Syndrome Scale (PANSS) were used to assess their depression, anxiety and psychotic symptoms, respectively.

The depression, anxiety, psychotic symptoms and blood sugar levels of the suicide attempt group were higher than those of the non-suicide attempt group. Correlation analysis showed that blood glucose was significantly associated with suicide attempts in male and female patients. FDI-6 in vitro While binary logistic regression showed that blood glucose levels were significantly associated with suicide attempts in male patients, it showed that suicide attempts were not significantly associated with blood glucose levels in female patients.

The main limitations are cross-sectional design and inability to control selection bias.

In male MDD patients, fasting blood glucose level is a potential biomarker of suicide attempt, which deserves attention to avoid suicide risk. However, in female patients, fasting blood glucose has no significant correlation to suicide attempts.

Parental attitudes towards the vaccines play a key role in the success of the herd immunity for the COVID-19. Psychological health seems to be a controversial determinant of vaccine hesitancy and remains to be investigated. This study attempted to measure parental psychological distress, attitudes towards the COVID-19 vaccine, and to explore the potential associations.

An online survey using convenience sampling method was conducted among parents within the school public health network of Shenzhen. Demographic information and attitudes towards COVID-19 vaccination were collected. The Patient Health Questionnaire (PHQ-4) was applied to measure psychological distress.

Overall, 4,748 parents were included (average age 40.28, standard deviation 5.08). More than one fifth of them demonstrated psychological distress, in which only 3.3% were moderate to severe symptom. The proportions of COVID-19 vaccine hesitancy for themselves, their spouses, and their children were 25.2%, 26.1%, and 27.3%, respectively. Parents with psychological distress were more likely to suffer vaccine hesitancy for themselves (OR 1.
