Peripartum depression (PPD) is a prevalent mental health disorder in the peripartum period. However, a recent systematic review of clinical guidelines relating to PPD has revealed a significant inconsistency in recommendations.
Aims
This study aimed to collect up-to-date evidence on the effectiveness of interventions and provide recommendations for prevention, screening and treating PPD.
Method
A series of umbrella reviews on the effectiveness of PPD prevention, screening and treatment interventions was conducted. A search was performed in five databases from 2010 until 2023. The guidelines were developed according to the GRADE framework and AGREE II Checklist recommendations. Public stakeholder review was included.
Results
One hundred and forty-five systematic reviews were included in the final analysis and used to form the guidelines. Forty-four recommendations were developed, including recommendations for prevention, screening and treatment. Psychological and psychosocial interventions are strongly recommended for preventing PPD in women with no symptoms and women at risk. Screening programmes for depression are strongly recommended during pregnancy and postpartum. Cognitive–behavioural therapy is strongly recommended for PPD treatment for mild to severe depression. Antidepressant medication is strongly recommended for treating severe depression in pregnancy. Electroconvulsive therapy is strongly recommended for therapy-resistant and life-threatening severe depression during pregnancy. Other recommendations are offered to healthcare professionals, stakeholders and researchers in managing PPD in different contexts.
Conclusion
Treatment recommendations should be implemented after carefully considering clinical severity, previous history, risk–benefit for mother and foetus/infant and women’s values and preferences. Implementation of evidence-based clinical practice guidelines within country-specific contexts should be facilitated.
Oral contraceptive pills (OCP) have received increased critical attention recently owing to their perceived link with mental health, especially among adolescent girls. The empirical literature, however, includes mixed findings on whether OCP use is associated with poorer mental health.
Aims
To examine the association between the use of OCP and internalising problems in adolescent girls.
Methods
This study was embedded in the iBerry study, a population-based cohort of adolescents oversampled for behavioural and emotional problems from the greater Rotterdam area, The Netherlands. In 372 girls, internalising problems were measured using the Youth Self Report, and use of OCP was determined by parental interview and self-report questionnaire across two subsequent waves (mean ages 14.9 and 17.9 years, respectively). Multiple regression analyses were performed to determine the association. Analyses were adjusted for various sociodemographic factors and adjusted for previous internalising problems assessed at a mean age of 14.9 years.
Results
In total, 204 girls (54.8%) used OCP. OCP use was associated with fewer internalising problems in adolescent girls compared with non-use (adjusted β = −2.22, 95% CI [−4.24, −0.20]; P = 0.031).
Conclusions
In this research, we found that adolescent girls using OCP reported fewer internalising problems compared with non-users. This association was most prominent for girls with pre-existing internalising problems. Although healthy user bias may have a role, our observations suggest a potential therapeutic benefit for those with greater baseline challenges.
A correlational measure for an n by p matrix X and an n by q matrix Y assesses their relation without specifying either as a fixed target. This paper discusses a number of useful measures of correlation, with emphasis on measures which are invariant with respect to rotations or changes in singular values of either matrix. The maximization of matrix correlation with respect to transformations XL and YM is discussed where one or both transformations are constrained to be orthogonal. Special attention is focussed on transformations which cause XL and YM to be n by s, where s may be any number between 1 and min (p, q). An efficient algorithm is described for maximizing the correlation between XL and YM where analytic solutions do not exist. A factor analytic example is presented illustrating the advantages of various coefficients and of varying the number of columns of the transformed matrices.
Trauma is prevalent amongst early psychosis patients and associated with adverse outcomes. Past trials of trauma-focused therapy have focused on chronic patients with psychosis/schizophrenia and comorbid Post-Traumatic Stress Disorder (PTSD). We aimed to determine the feasibility of a large-scale randomized controlled trial (RCT) of an Eye Movement Desensitization and Reprocessing for psychosis (EMDRp) intervention for early psychosis service users.
Methods
A single-blind RCT comparing 16 sessions of EMDRp + TAU v. TAU only was conducted. Participants completed baseline, 6-month and 12-month post-randomization assessments. EMDRp and trial assessments were delivered both in-person and remotely due to COVID-19 restrictions. Feasibility outcomes were recruitment and retention, therapy attendance/engagement, adherence to EMDRp treatment protocol, and the ‘promise of efficacy’ of EMDRp on relevant clinical outcomes.
Results
Sixty participants (100% of the recruitment target) received TAU or EMDR + TAU. 83% completed at least one follow-up assessment, with 74% at 6-month and 70% at 12-month. 74% of EMDRp + TAU participants received at least eight therapy sessions and 97% rated therapy sessions demonstrated good treatment fidelity. At 6-month, there were signals of promise of efficacy of EMDRp + TAU v. TAU for total psychotic symptoms (PANSS), subjective recovery from psychosis, PTSD symptoms, depression, anxiety, and general health status. Signals of efficacy at 12-month were less pronounced but remained robust for PTSD symptoms and general health status.
Conclusions
The trial feasibility criteria were fully met, and EMDRp was associated with promising signals of efficacy on a range of valuable clinical outcomes. A larger-scale, multi-center trial of EMDRp is feasible and warranted.
Increasing litter size has long been a goal of pig breeders and producers, and may have implications for pig (Sus scrofa domesticus) welfare. This paper reviews the scientific evidence on biological factors affecting sow and piglet welfare in relation to large litter size. It is concluded that, in a number of ways, large litter size is a risk factor for decreased animal welfare in pig production. Increased litter size is associated with increased piglet mortality, which is likely to be associated with significant negative animal welfare impacts. In surviving piglets, many of the causes of mortality can also occur in non-lethal forms that cause suffering. Intense teat competition may increase the likelihood that some piglets do not gain adequate access to milk, causing starvation in the short term and possibly long-term detriments to health. Also, increased litter size leads to more piglets with low birth weight which is associated with a variety of negative long-term effects. Finally, increased production pressure placed on sows bearing large litters may produce health and welfare concerns for the sow. However, possible biological approaches to mitigating health and welfare issues associated with large litters are being implemented. An important mitigation strategy is genetic selection encompassing traits that promote piglet survival, vitality and growth. Sow nutrition and the minimisation of stress during gestation could also contribute to improving outcomes in terms of piglet welfare. Awareness of the possible negative welfare consequences of large litter size in pigs should lead to further active measures being taken to mitigate the mentioned effects.
Seclusion is part of the clinical practice in European psychiatric hospital care with the aim to maintain the safety of patients and staff. Adverse events and harm have been reported for patients and staff resulting from seclusion. Safety hazards, which are the prerequisite of adverse events, can be identified using video observation methods. Identifying safety hazards can be used to prevent adverse events and improve the quality of psychiatric care.
Objectives
To identify safety hazards during seclusion in psychiatric hospital care.
Methods
Descriptive design with non-participant video-observation of seclusion care practice. Data consisted of video recordings (n = 36) from six wards of one psychiatric hospital in Finland. The data were analysed with inductive thematic analysis.
Results
Clinical practice of seclusion included safety hazards stemming from the actions of patients and staff. Patients’ actions were as follows: aggressive behaviour, attempting to escape, precarious movements, preventing the visibility of staff, exposing themselves to contamination, and falls during seclusion. Staff actions included: leaving dangerous items to seclusion, issues in the administration of medication, performing physical and mechanical restraints in unsecure way, and precarious movements and postures.
Conclusions
According to our results, the use of seclusion has safety hazards that can result in harm for patients and staff. To improve the quality and safety of seclusion in clinical practice, the guidelines, practices, and staff training need to consider the various safety hazards. While the work in Europe to abolish the use of seclusion is still in progress, this topic requires attention in clinical practice, education, and policymaking.
Rest-frame far-ultraviolet spectra are fundamental to our understanding of star-forming galaxies, providing a unique window on massive star populations (MSs), chemical evolution, feedback processes, and reionization. JWST is ushering in a new era, pushing the FUV frontier beyond z=10. The success of such endeavors hinges on a comprehensive understanding of the MSs and gas conditions that power the observed spectra. The COS Legacy Archive Spectroscopic SurveY (CLASSY) is a powerful and promising solution providing high-quality, high-resolution FUV spectra of 45 nearby star-forming galaxies. The spectra contain a suite of features that simultaneously characterize the MSs that populate metal-poor galaxies, physical properties of large-scale outflows, and chemical abundance patterns. The CLASSY sample is consistent with the z 0 mass-metallicity relationship and spans 1.5 dex in metallicity. These unique properties make CLASSY the benchmark training set for studies of MSs in star-forming galaxies both across cosmic time and connecting metal-poor to metal-rich populations.
Post-traumatic mechanisms are theorised to contribute to voice-hearing in people with psychosis and a history of trauma. Phenomenological links between trauma and voices support this hypothesis, as they suggest post-traumatic processes contribute to the content of, and relationships with, voices. However, research has included small samples and lacked theory-based comprehensive assessments.
Method
In people with distressing voices (n = 73) who experienced trauma prior to voice-hearing, trauma–voice links were assessed both independently and dependently (descriptions were presented and rated separately and together, respectively) by both participants and researchers. A structured coding frame assessed four types of independent links (i.e. victimisation type, physiological-behavioural, emotional, and cognitive response themes including negative self-beliefs) and three types of dependent links: relational (similar interaction with/response to, voice and trauma); content (voice and trauma content are exactly the same); and identity (voice identity is the same as perpetrator).
Results
Independent links were prevalent in participants (51–58%) and low to moderately present in researcher ratings (8–41%) for significant themes. Identification of negative self-beliefs in trauma was associated with a significantly higher likelihood of negative self-beliefs in voices [participants odds ratio (OR) 9.8; researchers OR 4.9]. Participants and researchers also reported many dependent links (80%, 66%, respectively), most frequently relational links (75%, 64%), followed by content (60%, 25%) and identity links (51%, 22%).
Conclusion
Trauma appears to be a strong shaping force for voice content and its psychological impact. The most common trauma–voice links involved the experience of cognitive-affective psychological threat, embodied in relational experiences. Trauma-induced mechanisms may be important intervention targets.
Chapter 11 illustrates different strategies to obtain reliable and robust trait data from both field sampling and experiments. An exercise is provided to familiarize readers with different alternatives for sampling traits, and their implications for sampling effort, providing advice on defining a realistic trait sampling campaign. Examples show that a feasible sampling strategy needs to sacrifice aspects of trait variability of lower importance for the ecological questions being asked and how researchers should attempt to compromise between the most accurate and most precise estimations of trait values. Special attention is given to the expected effect of species turnover vs intraspecific trait variability adjustments across gradients, depending on the extent of the studied environmental gradient. The choice of a given sampling scheme is framed into simple trade-offs between two extreme cases: sampling several individuals for each species from only a single population, or sampling one individual per species in each population in which the species occur along a gradient. A flowchart guide for choosing among different sampling combinations along this trade-off is provided.
Chapter 12 provides some key examples of how to use trait-based methods as a tool for biodiversity monitoring, one that often shows more sensitivity to environmental changes as compared to taxonomic-based metrics. The examples show how trait-based approaches can help to broaden the scope of applied environmental sciences, using ecological theory to solve different types of environmental issues of concern. Focusing on response and effect traits, a discussion is provided on how it is possible to restore or create new ecological communities that are more resilient to environmental changes, or that enhance desirable ecosystem services. Finally, it is argued that poor literacy in functional ecology might act as a barrier to communicating with decision makers, and incorporating trait-based approaches in environmental policies.
Chapter 6 analyses the ecological mechanisms, and implications, of intraspecific trait variability (ITV) and some key approaches to take ITV properly into account in modern trait-based analyses. The different sources of ITV, genetic variation, epigenetic effects and phenotypic plasticity, are discussed and put in the context of species evolution, adaptation to environmental conditions, species distribution potential (including invasive species) and the effects of species on multiple ecosystem properties and trophic interactions. Different tools are provided to quantify how strong ITV affect ecological patterns. A comparison of within- vs between-species trait variability in a community is discussed. Tools showing how strong the effect of changes in species composition (turnover) compared to ITV along environmental gradients are provided. Finally, methods considering ITV to quantify trait differences between species, via trait overlap in trait probability distributions, are discussed in the light of modern tools measuring functional diversity across different scales
Chapter 8 illustrates the importance of considering the phylogeny of species when investigating different ecological questions related to species traits. First, the concept of phylogenetic trees is provided with the notion that, in some cases, species that share a common ancestor share some common traits, while in others distantly related species have evolved similar adaptations independently. Models of evolution, in particular the Brownian motion model, are introduced to set a reference for comparing the extent of trait conservatism. The importance of phylogeny is first discussed with respect to ‘species level’ analyses (Chapter 4) relating traits, species environmental preferences and species fitness. Tests such as Phylogenetic Independent Contrasts (PICs) are discussed in terms of whether they provide, or not, a way to ‘correct’ for the phylogenetic non-independence between species. Then the concept of phylogenetic relatedness between species is discussed in the context of Phylogenetic Diversity (PD) indices and combined with functional diversity measurements. Different R tools are described to support these types of analyses in the material accompanying this book.
Chapter 3 provides an overview of the concepts and approaches needed to assess ecological and phenotypic differentiation between organisms. First, an historical perspective on earlier systems ‘classifying’ species in terms of their traits into different ‘types’ is provided. Second, other schemes such as the r/K continuum, the C-S-R scheme and the leaf economic spectrum are introduced. These approaches, aimed at defining different ‘types’ of organisms, are discussed in terms of their importance for interpreting ecological patterns and for communication with non-experts. A further distinction between response and effect functional groups is provided, with a guideline on how to define these groups with ‘a priori’ ecological hypotheses or ‘a posteriori’ data-driven approaches. The Gower distance is introduced as a useful way to characterize the differences between organisms in terms of multiple types of traits. At the same time, a number of often overlooked problems with this distance metric are discussed. The R material for this chapter illustrates these issues with practical examples.
