Assessment of the thymus in fetuses prior to spontaneous preterm birth using functional MRI.

Objectives: The aim of this study was to utilise T2* relaxometry (an indirect method of quantifying tissue oxygenation) to assess the fetal thymus in uncomplicated pregnancies throughout gestation and in a cohort of fetuses that subsequently deliver very preterm.

Methods: A control group of participants with low-risk pregnancies were recruited and retrospectively excluded if they developed any pregnancy related complications after scanning. Participants were recruited who were deemed to be at very high risk of delivery prior to 32 weeks' gestation and retrospectively excluded if they did not deliver prior to this gestation.

Anxiety, depression, and perceived wellbeing in antenatal women at risk of preterm birth: a retrospective cohort study.

Introduction: Women identified at risk for preterm may be vulnerable to developing mental health difficulties due to the increased likelihood of poor pregnancy outcome and uncertainty surrounding their delivery. Formal assessment of mental wellbeing in specialist preterm birth clinics is not routinely offered, but may offer the opportunity for early intervention.

Methods: We aimed to investigate if demographic characteristics and obstetric risk factors were associated with psychological wellbeing in women at risk of preterm birth.

INSIGHT-2: mechanistic studies into pregnancy complications and their impact on maternal and child health-study protocol.

Background: Pregnancy and early childhood cohorts provide a framework for investigating the complex interplay between early-life exposures and health outcomes, thereby informing prevention strategies and interventions to improve maternal and child health. In this paper, we outline the objectives, methodologies and expected contributions of INSIGHT-2, a comprehensive cohort study dedicated to advancing our understanding of pregnancy and pregnancy complications towards improving the health and well-being of mothers and their offspring.

Methods: Over the course of 5 years, the study aims to establish a diverse cohort of 1700 pregnant women and to follow up their children up to 2 years of age.

The Immunomodulatory Role of Regulatory T Cells in Preterm Birth and Associated Pregnancy Outcomes.

Spontaneous preterm birth (sPTB), defined as live birth before 37 weeks of gestational age, is associated with immune dysregulation and pro-inflammatory conditions that profoundly impact newborn health. The question of immune integrity at the maternal-foetal interface is a focus of recent studies centring not only sPTB but the conditions often affiliated with this outcome. Regulatory T cells (Tregs) play a critical anti-inflammatory role in pregnancy, promoting foetal tolerance and placentation.

Geopolitical determinants of mental health and global health inequities.

Geopolitical determinants of health have been well recognized by the World Health Organization and are increasingly being discussed across governments, institutions, academics, policy makers, and across global health sector. Geopolitical determinants of health are events, structures, processes, and factors that influence individual health including mental health, public and population mental health both directly and indirectly. Consequently, nation's responses to these factors will affect short-term and long-term health outcomes.

The experience of self-harming behaviours that inflict external injuries to the body in UK-based Bangladeshi, Indian and Pakistani women: a literature review.

Studies carried out on self-harm in the UK have consistently reported a higher level of self-harm among women with South Asian heritage resident in the UK when age-compared with other British women. The reasons for this variation are many including but not limited exclusively to family environment and gender role expectations. These studies have also shown that these women are also least likely to seek psychological support from mental health professionals again with a number of explanations including stigma against help-seeking, notions of shame and other culture-specific factors.

'Self-harm is wrong': the experience of self-harming behaviours that inflict external injuries to the body in UK-based Bangladeshi, Indian and Pakistani women: an Interpretative Phenomenological Analysis.

This study investigated the experience of self-harming behaviour that inflicts external injuries to the body in UK based Indian, Pakistani, and Bangladeshi (UKBIP) women. A total of eight participants were recruited via purposive sampling and semi-structured interviews were carried out. The interviews were analysed using Interpretative Phenomenological Analysis (IPA).

Perceived powerlessness and self-harming behaviours in UK-based Bangladeshi, Indian and Pakistani women.

This study investigated self-harming behaviours among UK-based women of Bangladeshi, Indian and Pakistani origin (UKBIP). Through purposive sampling, eight participants who had engaged in self-harm, specifically through cutting, were selected for semi-structured interviews. The qualitative data gathered from these interviews underwent analysis using interpretative phenomenological analysis (IPA), which involved analysis at individual and group levels.

Assessment of Health-Related Quality of Life of Stroke Survivors in Southeast Communities in Nigeria.

The prevalence of stroke in Nigeria has continued to be a major public health challenge. Recovery from a stroke episode can be a long-impacting process with reduced quality of life outcomes. Past studies have explored the quality of life (QoL) of stroke survivors.

Assessment of current biomarkers and interventions to identify and treat women at risk of preterm birth.

Preterm birth remains an important global problem, and an important contributor to under-5 mortality. Reducing spontaneous preterm birth rates at the global level will require the early identification of patients at risk of preterm delivery in order to allow the initiation of appropriate prophylactic management strategies. Ideally these strategies target the underlying pathophysiologic causes of preterm labor.

Comparing cervical cerclage, pessary and vaginal progesterone for prevention of preterm birth in women with a short cervix (SuPPoRT): A multicentre randomised controlled trial.

Background: Cervical cerclage, cervical pessary, and vaginal progesterone have each been shown to reduce preterm birth (PTB) in high-risk women, but to our knowledge, there has been no randomised comparison of the 3 interventions. The SuPPoRT "Stitch, Pessary, or Progesterone Randomised Trial" was designed to compare the rate of PTB <37 weeks between each intervention in women who develop a short cervix in pregnancy.

Methods And Findings: SuPPoRT was a multicentre, open label 3-arm randomised controlled trial designed to demonstrate equivalence (equivalence margin 20%) conducted from 1 July 2015 to 1 July 2021 in 19 obstetric units in the United Kingdom.

Predicting Preterm Birth Using Cell-Free Ribonucleic Acid.

Spontaneous preterm birth (sPTB) is a complex and clinically heterogeneous condition that remains incompletely understood, leading to insufficient interventions to effectively prevent it from occurring. Cell-free ribonucleic acid signatures in the maternal circulation have the potential to identify biologically relevant subtypes of sPTB. These could one day be used to predict and prevent sPTB in asymptomatic individuals, and to aid in prognosis and management for individuals presenting with threatened preterm labor and preterm prelabor rupture of membranes.

Corrigendum: Microbiota dynamics, metabolic and immune interactions in the cervicovaginal environment and their role in spontaneous preterm birth.

Microbiota dynamics, metabolic and immune interactions in the cervicovaginal environment and their role in spontaneous preterm birth.

Differences in the cervicovaginal microbiota are associated with spontaneous preterm birth (sPTB), a significant cause of infant morbidity and mortality. Although establishing a direct causal link between cervicovaginal microbiota and sPTB remains challenging, recent advancements in sequencing technologies have facilitated the identification of microbial markers potentially linked to sPTB. Despite variations in findings, a recurring observation suggests that sPTB is associated with a more diverse and less stable vaginal microbiota across pregnancy trimesters.

Amniotic fluid sludge is associated with earlier preterm delivery and raised cervicovaginal interleukin 8 concentrations.

Background: Preterm birth is the leading cause of global neonatal mortality. Amniotic fluid sludge, thought to indicate intra-amniotic infection, may have potential as a clinical biomarker of preterm birth risk.

Objective: This study aimed to analyze whether the presence of amniotic fluid sludge in pregnant participants with a known short cervical length can help improve the understanding of the etiology and guide management choice.

Longitudinal change in cervical length following vaginal or abdominal cervical cerclage: a randomized comparison.

Background: Cervical cerclage has been shown to reduce the risk of recurrent spontaneous preterm birth in a high-risk patient population; however, the mechanism is not well understood. Transabdominal cerclage is superior to low and high vaginal cerclage in reducing early spontaneous preterm birth and fetal loss in women with previous failed vaginal cerclage. Cervical length measurements are commonly used to monitor high-risk women and may explain the mechanism of success.

Sample-path large deviations for stochastic evolutions driven by the square of a Gaussian process.

Recently, a number of physical models have emerged described by a random process with increments given by a quadratic form of a fast Gaussian process. We find that the rate function which describes sample-path large deviations for such a process can be computed from the large domain size asymptotic of a certain Fredholm determinant. The latter can be evaluated analytically using a theorem of Widom which generalizes the celebrated Szegő-Kac formula to the multidimensional case.

Global mental health and climate change: A geo-psychiatry perspectiv.

Climate changes affect planet ecosystems, living beings, humans, including their lives, rights, economy, housing, migration, and both physical and mental health. Geo-psychiatry is a new discipline within the field of psychiatry studying the interface between various geo-political factors including geographical, political, economic, commercial and cultural determinants which affect society and psychiatry: it provides a holistic overview on global issues such as climate changes, poverty, public health and accessibility to health care. It identifies geopolitical factors and their effects at the international and national levels, as well as considers the politics of climate changes and poverty within this context.

Working with interpreters when working with forced migrants in mental health.

281 million people were recorded as having migrated across national borders by the United Nations in 2021, this equates to approximately 3.6 percent of the world's population. Forced migrants/refugees account for 12 per cent of all international migrants.

Guidance for clinicians when working with refugees and asylum seekers.

The contribution and role of psychologists, psychiatrists or mental health practitioners in working alongside forced migrants may take many forms. The guidance on which this paper is based, came about when several members of the British Psychological Society (including those with lived experience and insight and those who had set up services); became aware of the need for good practice guidance for clinicians working with refugees, asylum seekers including forced migrants across Britain. These guidelines cover a range of areas where clinicians work with individuals in clinical contexts, schools, nurseries, colleges and within community organisations.
