Accumulating evidence shows that an increasing number of children and young people (CYP) are reporting mental health problems.
Aims
To investigate emotional disorders (anxiety or depression) among CYP in England between 2004 and 2017, and to identify which disorders and demographic groups have experienced the greatest increase.
Method
Repeated cross-sectional, face-to-face study using data from the Mental Health of Children and Young People surveys conducted in 2004 and 2017, allowing use of nationally representative probability samples of CYP aged 5–16 years in England. A total of 13 561 CYP were included across both survey waves (6898 in 2004 and 6663 in 2017). We assessed the prevalence of any emotional, anxiety and depressive disorder assessed using the Development and Well-Being Assessment and classified according to ICD-10 criteria.
Results
The prevalence of emotional disorders increased from 3.9% in 2004 to 6.0% in 2017, a relative increase of 63% (relative ratio 1.63, 95% CI 1.38, 1.91). This was largely driven by anxiety disorders, which increased from 3.5 to 5.4% (relative ratio 1.63, 95% CI 1.37, 1.93). The largest relative changes were for panic disorder, separation anxiety, social phobia and post-traumatic stress disorder. Changes were similar for different genders and socioeconomic groups, but differed by ethnicity: the most pronounced increase was among White CYP (relative ratio 1.88, 95% CI 1.59, 2.24), compared with no clear change for Black and minority ethnic CYP (relative ratio 0.85, 95% CI 0.52, 1.39). Comorbid psychiatric conditions were present in over a third of CYP with emotional disorders, with the most common being conduct disorder.
Conclusions
Between 2004 and 2017, the increase in emotional disorders among CYP in England was largely driven by anxiety disorders. Socioeconomic inequalities did not narrow. Disaggregating by ethnicity, change was evident only in White CYP, suggesting differential trends in either risk exposure, resilience or reporting by ethnicity.
A linear stability model based on a phase-field method is established to study the formation of ripples on the ice surface. The pattern on horizontal ice surfaces, e.g. glaciers and frozen lakes, is found to be originating from a gravity-driven instability by studying ice–water–air flows with a range of water and ice thicknesses. Contrary to gravity, surface tension and viscosity act to suppress the instability. The results demonstrate that a larger value of either water thickness or ice thickness corresponds to a longer dominant wavelength of the pattern, and a favourable wavelength of 90 mm is predicted, in agreement with observations from nature. Furthermore, the profiles of the most unstable perturbations are found to be with two peaks at the ice–water and water–air interfaces whose ratio decreases exponentially with the water thickness and wavenumber.
The objective is to determine if a practical face-to-face emergency disaster incident response training program delivered in the clinical setting will improve self-reported confidence and assessed knowledge of emergency department (ED) nurses to respond to disasters.
Methods
A single site prospective pre-test and post-test randomized controlled trial was adopted for this study. The intervention was a practical face-to-face training program, while the control group completed the required annual mandatory hospital online training.
Results
There was a large difference in post-test median self-reported confidence between groups. There was also a large difference in the proportion of subjects who reached satisfactory levels of self-reported confidence post-test. Regarding assessed knowledge, there was a moderate difference in post-test median knowledge between groups. There was also a moderate difference in the proportion who reached satisfactory levels of knowledge post-test.
Conclusions
This study has shown that ED nurses who undertake a practical face-to-face disaster preparedness education program in the clinical setting, are better prepared to respond to emergency disaster incidents. Organizations should consider the use of a practical structured face-to-face emergency disaster incident response education program to complement and enhance any online emergency and disaster training.
In this work, a systematic study is carried out concerning the dynamic behaviour of finite-size spheroidal particles in non-isothermal shear flows between parallel plates. The simulations rely on a hybrid method combining the lattice Boltzmann method with a finite-difference solver. Fluid–particle and heat–particle interactions are accounted for by using the immersed boundary method. The effect of particle Reynolds number ($\textit{Re}_p=1{-}90$), Grashof number (${Gr}=0{-}200$), initial position and initial orientation of the particle are thoroughly examined. For the isothermal prolate particle, we observed that above a certain Reynolds number, the particle undergoes a pitchfork bifurcation; at an even higher Reynolds number, it returns to the centre position. In contrast, the hot particle behaves differently, with no pitchfork bifurcation. Instead, the Reynolds and Grashof numbers can induce oscillatory tumbling or log-rolling motions in either the lower or upper half of the channel. Heat transfer also plays an important role: at low Grashof numbers, the particle settles near the lower wall, while increasing the Grashof number shifts it towards the upper side. Moreover, the presence of thermal convection increases the rotational speed of the particle. Surprisingly, beyond the first critical Reynolds number, the equilibrium position of the thermal particle shifts closer to the centreline compared with that of a neutrally buoyant isothermal particle. Moreover, higher Grashof numbers can cause the particle to transition from tumbling to log-rolling or even a no-rotation mode. The initial orientation has a stronger influence at low Grashof numbers, while the initial position shows no strong effect in non-isothermal cases.
Semi-simplicial and semi-cubical sets are commonly defined as presheaves over, respectively, the semi-simplex or semi-cube category. Homotopy type theory then popularized an alternative definition, where the set of $n$-simplices or $n$-cubes are instead regrouped into the families of the fibers over their faces, leading to a characterization we call indexed. Moreover, it is known that semi-simplicial and semi-cubical sets are related to iterated Reynolds parametricity, respectively, in their unary and binary variants. We exploit this correspondence to develop an original uniform indexed definition of both augmented semi-simplicial and semi-cubical sets, and fully formalize it in Coq.
Electronic health records (EHRs), increasingly available in low- and middle-income countries (LMICs), provide an opportunity to study transdiagnostic features of serious mental illness (SMI) and its trajectories.
Aims
Characterise transdiagnostic features and diagnostic trajectories of SMI using an EHR database in an LMIC institution.
Method
We conducted a retrospective cohort study using EHRs from 2005–2022 at Clínica San Juan de Dios Manizales, a specialised mental health facility in Colombia, including 22 447 patients with schizophrenia (SCZ), bipolar disorder (BPD) or severe/recurrent major depressive disorder (MDD). Using diagnostic codes and clinical notes, we analysed the frequency of suicidality and psychosis across diagnoses, patterns of diagnostic switching and the accumulation of comorbidities. Mixed-effect logistic regression was used to identify factors influencing diagnostic stability.
Results
High frequencies of suicidality and psychosis were observed across diagnoses of SCZ, BPD and MDD. Most patients (64%) received multiple diagnoses over time, including switches between primary SMI diagnoses (19%), diagnostic comorbidities (30%) or both (15%). Predictors of diagnostic switching included mentions of delusions (odds ratio = 1.47, 95% CI 1.34–1.61), prior diagnostic switching (odds ratio = 4.01, 95% CI 3.7–4.34) and time in treatment, independent of age (log of visit number; odds ratio = 0.57, 95% CI 0.54–0.61). Over 80% of patients reached diagnostic stability within 6 years of their first record.
Conclusions
Integrating structured and unstructured EHR data reveals transdiagnostic patterns in SMI and predictors of disease trajectories, highlighting the potential of EHR-based tools for research and precision psychiatry in LMICs.
This study investigates noise generation from co-rotating rotors arranged in a side-by-side configuration. The analysis examines the effects of different phase delays and separation distances. A simple mathematical model is developed to provide insight into constructive and destructive noise interference. An experimental campaign was carried out to validate the proposed analytical model. Furthermore, the study introduces a space–time proper orthogonal decomposition technique to separate broadband and tonal components. Subsequently, wavelet analysis is applied to the tonal component, revealing a transition to chaos via intermittency, characterised by the local birth and decay of periodic oscillations. This phenomenon highlights the intricate and fascinating chaotic nature of interference transitions. The chaotic behaviour of the tonal component is related to the macro time scale of pressure fluctuations, and has been incorporated into the mathematical model. This model has several applications, including its potential use in the development of active control systems and the design of quieter distributed propulsion systems.
In the past 20 years, there has been growing interest in post-traumatic stress disorder (PTSD) in people with intellectual disabilities. It is now widely recognised that individuals with intellectual disabilities are more likely to be affected by traumatic experiences than those without. The authors discuss advancements in understanding trauma and PTSD in individuals with intellectual disabilities, as well as improvements in clinical assessment and treatment. They also emphasise the need for further research into the effects of trauma and PTSD on this vulnerable and often marginalised population.
Although some modern popular songs are deliberately composed for the purpose of commentary or protest, most are produced for commercial reasons. However, such songs may nonetheless be adopted by political, cultural, and social movements, and in these cases, fans’ participatory meaning-making has an important role in the songs’ new purpose. Taking the 1935 Korean ballad ‘Tears of Mokp’o’ as a representative example, this article traces how the melancholy love song acquired successive layers of meaning against the backdrop of changing politico-economic contexts throughout the twentieth century. Drawing on political, popular music, and sports histories, I first examine how ‘Tears of Mokp’o’ became known as an anti-colonial anthem under Japanese rule, a position that persisted in postwar South Korea. I then investigate the ways in which fans of the Haitai Tigers, a professional baseball team, utilized the song to express a complex set of emotions and commitments regarding their politically oppressed and economically neglected home region of Chŏlla. Against the backdrop of their traumatic memories of the 1980 Kwangju Uprising, Haitai fans, through their collective singing of ‘Tears of Mok’po’ in stadiums during games, transformed it from a colonial-era pop hit/anti-colonial anthem into a baseball fight song that expressed their spirit of regional insubordination in the 1980s and 1990s. Entering the twenty-first century, ‘Tears of Mok’po’ no longer played the same role for the Tigers and their fans, and it receded into historical memory. This change in meaning and association shows how the political and historical meaning-making of popular songs can be constructed, reintegrated, and even dismissed.
Historians of the Indian Partition focus on the permit systems the governments of India and Pakistan put in place to stem refugee entry and prevent the return of evacuees. However, the prevention of exit became, alongside non-entrée and the prevention of return, part of an official strategy of immobility in South Asia directed at marginalized castes. At Partition, Pakistan saw the labour of ‘non-Muslim’ marginalized castes as essential to its national wealth. It believed it had to retain them at all costs. On the other side of the border, the article discusses the Indian government’s laggardly, and often indifferent, response to the struggles of caste-oppressed groups trying to migrate to India. The article builds on scholarship on mobility capital and partial citizenship in the aftermath of Partition to argue that with the prevention of exit, citizenship incorporated an imposed nationalization that embodied the status of marginalized castes as more than a minority and produced a form of bonded citizenship.
A considerable knowledge gap exists in relation to the presence and even existence of seagrass within Northern Ireland’s waters. Peer-reviewed publications on the historical ecology of seagrass are scarce and a collated timeline of references directly focusing on Northern Irish seagrasses does not exist. Recognising abiotic and biotic induced environmental change within key marine features such as seagrass is vital when attempting to measure the biodiversity and carbon sequestration services they provide. The research undertaken during this study identified three distinct periods within the archival records, which could be matched to the ecological history of seagrass in Northern Ireland. The first period (extensive and dense seagrass meadows from 1790 to 1880) was characterised by extensive seagrass meadows which were dense and healthy. The second period (degradation from 1880 to 1940) saw the beginnings of decline in seagrass from the 1790s, initially from anthropogenic influences and later from the seagrass wasting disease) and the final period (signs of recovery from 1940 to present day) showed small amounts of local regrowth of seagrass but at far reduced densities compared to the historical baseline described. These three defined periods all delivered varying degrees of anthropogenic stressors which determined the conservational health of seagrass in Northern Ireland. Seagrass habitats have become integral components in future-proofing the coastal marine environment against the effects of climate change and its associated impacts. Therefore, it is envisaged that the historical baseline that this manuscript provides will greatly benefit habitat managers in protecting, repairing, and restoring lost seagrass meadows.
Microswimmers display an intriguing ability to navigate through fluids with spatially varying viscosity, a behaviour known as viscotaxis, which plays a crucial role in guiding their motion. In this study, we reveal that the orientation dynamics of chiral squirmers in fluids with uniform viscosity gradients can be elegantly captured using the Landau–Lifshitz–Gilbert equations, originally developed for spin systems. Remarkably, we discover that chiral swimmers demonstrate negative viscotaxis, tracing spiral trajectories as they move. Specifically, a chiral squirmer with a misaligned source dipole and rotlet dipole exhibits a steady-state spiral motion – a stark contrast to the linear behaviour observed when the dipoles are aligned. This work provides fresh insights into the intricate interplay between microswimmer dynamics and fluid properties.
The monumental alignments found in southern Brittany, particularly Carnac, potentially mark the beginnings of the megalithic tradition in north-west Europe. Radiocarbon dates from excavations at a previously unknown section of this extensive megalithic complex, presented here, provide new insights into the dynamic history of construction during the fifth millennium cal BC. This refined chronology reveals not only that the site of Le Plasker—consisting of a pre-megalithic monumental tomb, alignments of standing stones and hearths—developed over 300 years in the Middle Neolithic, but that the choice of location may have been influenced by an earlier Late Mesolithic occupation.
Nurses play a critical role in preventing health care-acquired infections (HAIs) by applying infection control practices during hospitalization, in health care settings, and after patient discharge. Our aim was to evaluate the effect of an HAIs educational workshop on the knowledge, attitude, and practice of pediatric nurses at Al-Mezan Hospitals in Palestine.
Methods
A quasi-experimental study was conducted in 2022 among 44 pediatric nurses working in the PICU, NICU, pediatric ward, and nursery departments. Data were collected using demographic, knowledge, attitude, and practice questionnaires before and after the intervention. The educational workshop consisted of 4 sessions, each lasting 45 minutes. Data were analyzed using SPSS version 23, including descriptive statistics and paired t tests, with a significance level set at P < 0.05.
Results
Post-intervention scores showed significant improvements: knowledge increased from 52.9 ± 3.3 to 61.9 ± 4.1, attitude from 44.1 ± 4.1 to 52.6 ± 3.4, and practice from 42.1 ± 5.7 to 53.3 ± 3.3. All changes were statistically significant (P ≤ 0.001), indicating the effectiveness of the workshop.
Conclusions
The HAIs educational workshop significantly enhanced the knowledge, attitudes, and practices of pediatric nurses regarding infection control. These findings highlight the importance of continuous education and training programs to improve health care quality and patient safety.
