Investigating the impact of the COVID-19 pandemic on older adolescents' psychological wellbeing and self-identified cognitive difficulties.

Background: The COVID-19 pandemic coincides with growing concern regarding the mental health of young people. Older adolescents have faced a particular set of pandemic-related challenges and demonstrate heightened vulnerability to affective disorders (particularly anxiety). Anxiety symptoms are associated with a range of cognitive difficulties.

Mothers' symptoms of anxiety and depression and the development of child temperament: A genetically informative, longitudinal investigation.

Background: Child temperament traits and mothers' emotional symptoms relating to anxiety and depression may drive changes in one another, leading to their 'co-development' across time. Alternatively, links between mother and child traits may be attributable to shared genetic propensities. We explored longitudinal associations between mothers' emotional symptoms and child temperament traits and adjusted for genetic effects shared across generations.

Physical properties of short chain aqueous organosulfate aerosol.

Organosulfates comprise up to 30% of the organic fraction of aerosol. Organosulfate aerosol physical properties, such as water activity, density, refractive index, and surface tension, are key to predicting their impact on global climate. However, current understanding of these properties is limited.

Shoaling behaviour in response to turbidity in three-spined sticklebacks.

Many fresh and coastal waters are becoming increasingly turbid because of human activities, which may disrupt the visually mediated behaviours of aquatic organisms. Shoaling fish typically depend on vision to maintain collective behaviour, which has a range of benefits including protection from predators, enhanced foraging efficiency and access to mates. Previous studies of the effects of turbidity on shoaling behaviour have focussed on changes to nearest neighbour distance and average group-level behaviours.

No evidence for direct thermal carryover effects on starvation tolerance in the obligate blood-feeder, .

Thermal stress during development can prime animals to cope better with similar conditions in later life. Alternatively, negative effects of thermal stress can persist across life stages and result in poorer quality adults (negative carryover effects). As mean temperatures increase due to climate change, evidence for such effects across diverse taxa is required.

Secondary data analysis of social care records to examine the provision of mental health support for young people in care.

Background: Young people in care are much more likely to experience mental health difficulties than the general population, yet little is known about the provision of mental health support for this group in the United Kingdom.

Methods: Using routinely collected social care data, we explored the provision of mental health support for 112 young people in care in the UK. We identified young people experiencing elevated internalising or externalising difficulties in their first year in care (based on strengths and difficulties questionnaire scores) and extracted data on mental health referrals and provision.

Twins Early Development Study (TEDS): A genetically sensitive investigation of mental health outcomes in the mid-twenties.

The Twins Early Development Study (TEDS) is a longitudinal study following a cohort of twins born 1994-1996 in England and Wales. Of the 13,759 families who originally consented to take part, over 10,000 families remain enrolled in the study. The current focus of TEDS is on mental health in the mid-twenties.

Habitat geometry rather than visual acuity limits the visibility of a ground-nesting bird's clutch to terrestrial predators.

The nests of ground-nesting birds rely heavily on camouflage for their survival, and predation risk, often linked to ecological changes from human activity, is a major source of mortality. Numerous ground-nesting bird populations are in decline, so understanding the effects of camouflage on their nesting behavior is relevant to their conservation concerns. Habitat three-dimensional (3D) geometry, together with predator visual abilities, viewing distance, and viewing angle, determine whether a nest is either visible, occluded, or too far away to detect.

Phenotypic response to different predator strategies can be mediated by temperature.

Temperature change affects biological systems in multifaceted ways, including the alteration of species interaction strengths, with implications for the stability of populations and communities. Temperature-dependent changes to antipredatory responses are an emerging mechanism of destabilization and thus there is a need to understand how prey species respond to predation pressures in the face of changing temperatures. Here, using ciliate protozoans, we assess whether temperature can alter the strength of phenotypic antipredator responses in a prey species and whether this relationship depends on the predator's hunting behavior.

Cystoscopic removal of transvaginal mesh: Long-term outcomes.

Objectives: This study's aim is to evaluate the long-term quality of life and functional outcomes following cystoscopic excision of stress urinary incontinence (SUI) and pelvic organ prolapse (POP) mesh extruded into the urinary tract in women.

Patients And Methods: A retrospective chart review was performed of all cases of cystoscopic removal of extruded mesh at our high-volume tertiary care centre between April 2013 and August 2021. Postoperative patient-reported outcomes were collected via questionnaires: Urogenital Distress Inventory Short Form (UDI-6), EQ-5D-5L Visual analogue scale, ICIQ-Satisfaction (ICIQ-S) and additional questions regarding postoperative sexual function.

Vacuum ultraviolet photodissociation of sulfur dioxide and its implications for oxygen production in the early Earth's atmosphere.

The emergence of molecular oxygen (O) in the Earth's primitive atmosphere is an issue of major interest. Although the biological processes leading to its accumulation in the Earth's atmosphere are well understood, its abiotic source is still not fully established. Here, we report a new direct dissociation channel yielding S(D) + O(aΔ/XΣ) products from vacuum ultraviolet (VUV) photodissociation of SO in the wavelength range between 120 and 160 nm.

Mendelian randomisation studies of Attention Deficit Hyperactivity Disorder.

Background: Observational studies have found Attention Deficit Hyperactivity Disorder (ADHD) to be associated with an increased risk of adverse outcomes as well as with early risk factors; however it is not clear whether these associations reflect causal effects. Alternatives to traditional observational studies are needed to investigate causality: one such design is Mendelian randomization (MR), which uses genetic variants as instrumental variables for the exposure.

Methods: In this review we summarise findings from approximately 50 studies using MR to examine potentially causal associations with ADHD as either an exposure or outcome.

Childhood trajectories of internalising and externalising problems associated with a polygenic risk score for neuroticism in a UK birth cohort study.

Background: Neuroticism represents a personality disposition towards experiencing negative emotions more frequently and intensely. Longitudinal studies suggest that neuroticism increases risk of several psychological problems. Improved understanding of how this trait manifests in early life could help inform preventative strategies in those liable to neuroticism.

Factors mitigating the harmful effects of intimate partner violence on adolescents' depressive symptoms-A longitudinal birth cohort study.

Background: Preventing parental intimate partner violence (IPV) or mitigating its negative effects early in the lifecourse is likely to improve population mental health. However, prevention of IPV is highly challenging and we know very little about how the mental health of children exposed to IPV can be improved. This study assessed the extent to which positive experiences were associated with depressive symptoms among children with and without experience of IPV.

Social, emotional and behavioural difficulties associated with persistent speech disorder in children: A prospective population study.

Purpose: Social, emotional and behavioural difficulties (SEBD) in childhood are associated with negative consequences across the life course. Children with developmental language disorder have been identified as being at risk of developing SEBD but it is unclear whether a similar risk exists for children with speech sound disorder, a condition which impacts on children's ability to make themselves understood and has been shown to be associated with poor educational outcomes.

Methods: Participants were children who attended the 8-year-old clinic in the Avon Longitudinal Study of Parents and Children ( = 7390).

Methodological Challenges in Group-based Randomised Controlled Trials for Intimate Partner Violence Perpetrators: A Meta-summary.

Evidence for treatment effects of group-based Intimate Partner Violence (IPV) perpetrators programmes remains, at best, inconclusive. In the present review, systematic/meta-analytic reviews were used to identify randomised controlled trials and a meta-summary approach was employed to identify methodological challenges in the design and conduct of these trials. Of the fifteen studies identified, seven were comparative effectiveness trials.

Ventilatory Efficiency Is Reduced in People With Hypertension During Exercise.

Background An elevated ventilatory efficiency slope during exercise (minute ventilation/volume of expired CO; V/VCO slope) is a strong prognostic indicator in heart failure. It is elevated in people with heart failure with preserved ejection, many of whom have hypertension. However, whether the V/VCO slope is also elevated in people with primary hypertension versus normotensive individuals is unknown.

Examining the Relationship Between Trauma, Post-Traumatic Stress Disorder and Psychosis in Patients in a UK Secondary Care Service.

Objective: Traumatic experiences and post-traumatic stress disorder (PTSD) are common in schizophrenia. However, few studies screening for PTSD have established the temporality of PTSD-related traumatic events to psychosis onset. Furthermore, it is unclear how many patients attribute a trauma-based contribution to their psychosis or would find trauma-focused therapy acceptable.

Where and how have written action plans for atopic eczema/dermatitis been developed and evaluated? Systematic review.

Background: Atopic eczema/dermatitis is a common inflammatory condition which affects 15%-30% of children and 2%-10% of adults. It can have a significant impact and its management can be challenging. It is important for patients, parents, and caregivers to know how to look after their skin.

Corridor quality buffers extinction under extreme droughts in experimental metapopulations.

Corridors with good-quality habitats maintain the spatial dynamics of metapopulations by promoting dispersal between habitat patches, potentially buffering populations, and communities against continued global change. However, this function is threatened by habitats becoming increasingly fragmented, and habitat matrices becoming increasingly inhospitable, potentially reducing the resilience and persistence of populations. Yet, we lack a clear understanding of how reduced corridor quality interacts with rates of environmental change to destabilize populations.

Exploring the potential of ZnO-Ag@AgBr/SBA-15 Z-scheme heterostructure for efficient wastewater treatment: synthesis, characterization, and real-world applications.

This study reports on the synthesis and characterization of ZnO-Ag@AgBr/SBA-15 composites using natural halloysite clay from Yenbai Province, Vietnam, as a silica aluminum source. The synthesized materials demonstrated visible light absorption with a band gap energy range of 2.63-2.

Digital tools for assessing chronic pain in children (5-11 years): Systematic review.

Pediatric chronic pain places a significant burden on children, their families, and healthcare services. Effective pain measurement is needed for both clinical management and research. Digital pain measurement tools have been developed for adult and adolescent populations however less is known about measurement in younger children.

Striatal Dopamine Loss in Early Parkinson's Disease: Systematic Review and Novel Analysis of Dopamine Transporter Imaging.

Background: Neuropathological studies, based on small samples, suggest that symptoms of Parkinson's disease (PD) emerge when dopamine/nigrostriatal loss is around 50-80%. Functional neuroimaging can be applied in larger numbers during life, which allows analysis of the extent of dopamine loss more directly.

Objective: To quantify dopamine transporter (DaT) activity by neuroimaging in early PD.
