Obesity, antenatal depression, diet and gestational weight gain in a population cohort study

PURPOSE: The aims of this paper are to examine: (1) the relationship between high pre-pregnancy BMI and antenatal depression; (2) whether BMI and antenatal depression interact to predict diet and gestational weight gain (GWG). METHODS: Data came from the Avon Longitudinal Study of Parents and Children (ALSPAC). Underweight women were excluded. Pre-pregnancy BMI was self-reported and antenatal depression was assessed using the Edinburgh Postnatal Depression Scale at 18 and 32 weeks' gestation to identify persistently elevated depressive symptoms (EPDS>12). Dietary patterns were calculated from food frequency questionnaires at 32 weeks' gestation. GWG was categorised using the USA Institute of Medicine guidelines. RESULTS: This study included 13,314 pregnant women. Obese women had significantly higher odds of antenatal depression than normal weight controls after adjusting for socio-demographics and health behaviours (aOR 1.39, 95%CI 1.05-1.84). Every unit increase in pre-pregnancy BMI was associated with approximately 3% higher odds of antenatal depression (aOR 1.03, 95%CI 1.01-1.05). Antenatal depression was not meaningfully associated with dietary patterns after adjusting for confounders and was not associated with inadequate or excessive GWG. There was no evidence for an interaction of depression and BMI on either diet or GWG. CONCLUSIONS: Healthcare professionals should be aware of the dose-response relationship between high pre-pregnancy BMI and antenatal depression

Maternal personality traits, antenatal depressive symptoms and the postpartum mother-infant relationship: a prospective observational study

PURPOSE: Maternal depression has been associated with bonding difficulties and lower maternal sensitivity in observed mother-infant interactions. However, little research has examined the impact of disordered personality traits in mothers on these outcomes. We investigated the association between disordered personality traits in mothers measured during pregnancy and postnatal (a) self-reported bonding with infant; (b) observational mother-infant interactions. // METHODS: Five hundred fifty-six women were recruited during early pregnancy and subsequently followed up at mid-pregnancy (approximately 28 weeks' gestation) and when infants were aged approximately 3 months (n = 459). During early pregnancy, data were collected on disordered personality traits (using the Standardised Assessment of Personality Abbreviated Scale) and depressive symptoms (using the Edinburgh Postnatal Depression Scale). At 3 months postpartum, self-reported perceived bonding (using the Postpartum Bonding Questionnaire) were collected. A sub-sample of women additionally provided observational mother-infant interaction data (n = 206) (coded using the Child-Adult Relationship Experimental Index). // RESULTS: Higher disordered personality traits was not associated with maternal perceptions of bonding impairment, but was associated with reduced maternal sensitivity during observational mother-infant interactions [adjusted for age, education, having older children, substance misuse prior to pregnancy, infant sex and gestational age: coefficient = - 0.28, 95% CI = - 0.56 to - 0.00, p < 0.05]. After adjusting for depressive symptoms, the association was attenuated [coefficient = - 0.19, 95% CI = - 0.48 to 0.11, p = 0.217]. // CONCLUSIONS: Mothers with disordered personality traits did not perceive themselves as having bonding impairments with their infants but were less sensitive during observed interactions, though depressive symptoms attenuated this relationship. Both depression and disordered personality traits need to be addressed to optimize mother-infant interactions

Patients' experiences of assessment and detention under mental health legislation: systematic review and qualitative meta-synthesis

Background Understanding patient experiences of detention under mental health legislation is crucial to efforts to reform policy and practice. Aims To synthesise qualitative evidence on patients' experiences of assessment and detention under mental health legislation. Method Five bibliographic databases were searched, supplemented by reference list screening and citation tracking. Studies were included if they reported on patient experiences of assessment or detention under mental health legislation; reported on patients aged 18 years or older; collected data using qualitative methods; and were reported in peer-reviewed journals. Findings were analysed and synthesised using thematic synthesis. Results The review included 56 papers. Themes were generally consistent across studies and related to information and involvement in care, the environment and relationships with staff, as well as the impact of detention on feelings of self-worth and emotional state. The emotional impact of detention and views of its appropriateness varied, but a frequent theme was fear and distress during detention, including in relation to the use of force and restraint. Where staff were perceived as striving to form caring and collaborative relationships with patients despite the coercive nature of treatment, and when clear information was delivered, the negative impact of involuntary care seemed to be reduced. Conclusions Findings suggest that involuntary in-patient care is often frightening and distressing, but certain factors were identified that can help reduce negative experiences. Coproduction models may be fruitful in developing new ways of working on in-patient wards that provide more voice to patients and staff, and physical and social environments that are more conducive to recovery

A Pilot Programme to Facilitate the Use of Mental Health Treatment Requirements: Professional Stakeholders' Experiences

Mental Health Treatment Requirements (MHTRs) have been available in England and Wales since 2005 but are rarely used, despite high rates of mental health problems amongst offenders. In 2018, a new protocol to facilitate the use of MHTRs was piloted in five sites in England. Aims: Understanding the experiences of professional stakeholders and identify barriers to use MHTRs. Methods: Semi-structured qualitative interviews were conducted with thirty-eight professional stakeholders and thematic analysis applied. Results: Interviewees were positive about the content and implementation of the new protocol. Interviewees described key benefits as increasing options in community sentencing, addressing a gap in service provision and facilitating offenders’ access to other services. Challenges described, included multi-agency working, sustainability of funding and the range and complexity of needs of offenders receiving MHTRs and the variation in their motivation to engage. Success factors described were having a strong steering group, staff dedicated to the project and being able to provide a broad range of support to meet offender needs. Conclusion: The MHTR pilot protocol was generally well-received and appeared to address previous barriers to the use of MHTRs. Future work is needed to evaluate the effectiveness of MHTRs and the experience of offenders who receive them

Socio-economic status influences the relationship between obesity and antenatal depression: Data from a prospective cohort study

Background Obesity has been associated with increased risk of antenatal depression, but little is known about this relationship. This study tested whether socio-economic status (SES) influences the relationship between obesity and antenatal depression. Methods Data were taken from the Screening for Pregnancy Endpoints (SCOPE) cohort. BMI was calculated from measured height and weight at 15±1 weeks' gestation. Underweight women were excluded. SES was indicated by self-reported household income (dichotomised around the median: low SES ≤£45,000; high SES >£45,000). Antenatal depression was defined as scoring ≥13 on the Edinburgh Postnatal Depression Scale at both 15±1 and 20±1 weeks' gestation, to identify persistently elevated symptoms of depression. Results Five thousand five hundred and twenty two women were included in these analyses and 5.5% had persistently elevated antenatal depression symptoms. There was a significant interaction between SES and BMI on the risk of antenatal depression (p=0.042). Among high SES women, obese women had approximately double the odds of antenatal depression than normal weight controls (AOR 2.11, 95%CI 1.16–3.83, p=0.014, adjusted for confounders). Among low SES women there was no association between obesity and antenatal depression. The interaction effect was robust to alternative indicators of SES in sensitivity analyses. Limitations 1) Antenatal depression was assessed with a self-reported screening measure; and 2) potential mediators such as stigma and poor body-image could not be examined. Conclusions Obesity was only associated with increased risk of antenatal depression among high SES women in this sample. Healthcare professionals should be aware that antenatal depression is more common among low SES women, regardless of BMI category

Crisis-planning interventions for people with psychotic illness or bipolar disorder: systematic review and meta-analyses

Background Mental health services lack a strong evidence base on the most effective interventions to reduce compulsory admissions. However, some research suggests a positive impact of crisis-planning interventions in which patients are involved in planning for their future care during a mental health crisis. Aims This review aimed to synthesise randomised controlled trial (RCT) evidence on the effectiveness of crisis-planning interventions (for example advance statements and joint crisis plans) in reducing rates of compulsory hospital admissions for people with psychotic illness or bipolar disorder, compared with usual care (PROSPERO registration number: CRD42018084808). Method Six online databases were searched in October 2018. The primary outcome was compulsory psychiatric admissions and secondary outcomes included other psychiatric admissions, therapeutic alliance, perceived coercion and cost-effectiveness. Bias was assessed using the Cochrane collaboration tool. Results The search identified 1428 studies and 5 RCTs were eligible. One study had high risk of bias because of incomplete primary outcome data. Random-effects meta-analysis showed a 25% reduction in compulsory admissions for those receiving crisis-planning interventions compared with usual care (risk ratio 0.75, 95% CI 0.61–0.93, P = 0.008; from five studies). There was no statistical evidence that the intervention reduced the risk of voluntary or combined voluntary and compulsory psychiatric admissions. Few studies assessed other secondary outcomes. Conclusions Our meta-analysis suggests that crisis-planning interventions substantially reduce the risk of compulsory admissions among individuals with psychotic illness or bipolar disorder. Despite common components, interventions varied in their content and intensity across the trials. The optimal models and implementation of these interventions require further investigation

Effect of interchain separation on the photoinduced absorption spectra of polycarbazolyldiacetylenes

The photoinduced absorption spectra of a novel polycarbazolyldiacetylene with long aliphatic chains on the carbazolyl side groups are measured and compared with those of the unsubstituted polyDCHD. The two polymers in the blue form exhibit very similar electronic absorption spectra and Raman frequencies. This fact indicates that the conjugation length of the polydiacetylene backbone is not too affected by the long substituents. In contrast, the near steady-state photoinduced absorption spectra show that different photogeneration mechanisms are involved in the two polymers. This result can be ascribed to the role played by the interchain distance in the dynamics of the relaxation processes in polydiacetylenes

The role of bacteria in the pathogenesis and progression of idiopathic pulmonary fibrosis

Rationale:Idiopathic pulmonaryfibrosis (IPF)isa progressivelung disease of unknown cause that leads to respiratory failure and death within 5 years of diagnosis. Overt respiratory infection and immunosuppression carry a high morbidity and mortality, and polymorphisms in genes related to epithelial integrity and host defense predispose to IPF. Objectives: To investigate the role of bacteria in the pathogenesis and progression of IPF. Methods: We prospectively enrolled patients diagnosed with IPF according to international criteria together with healthy smokers, nonsmokers, and subjectswithmoderate chronic obstructive pulmonary disease as control subjects. Subjects underwent bronchoalveolar lavage (BAL), from which genomic DNA was isolated. The V3–V5 region of the bacterial 16S rRNA gene was amplified, allowing quantification of bacterial load and identification of communities by 16S rRNA quantitative polymerase chain reaction and pyrosequencing. Measurements and Main Results: Sixty-five patients with IPF had double the burden of bacteria in BAL fluid compared with 44 control subjects. Baseline bacterial burden predicted the rate of decline in lung volume and risk of death and associated independently with the rs35705950 polymorphism of the MUC5B mucin gene, a proven host susceptibilityfactorfor IPF. Sequencing yielded912,883 high-quality reads from all subjects.WeidentifiedHaemophilus, Streptococcus,Neisseria, and Veillonella spp. to be more abundant in cases than control subjects. Regression analyses indicated that these specific operational taxonomic units as well as bacterial burden associated independently with IPF. Conclusions: IPF is characterized by an increased bacterial burden in BAL that predicts decline in lung function and death. Trials of antimicrobial therapy are needed to determine if microbial burden is pathogenic in the disease
