Estimating the risk of developing bipolar disorder (BD) in children and adolescents (C&A) with depressive disorders is important to optimize prevention and early intervention efforts. We aimed to quantitatively examine the risk of developing BD from depressive disorders and identify factors which moderate this development.
Methods
In this systematic review and meta-analysis (PROSPERO:CRD42023431301), PubMed and Web-of-Science databases were searched for longitudinal studies reporting the percentage of C&A with ICD/DSM-defined depressive disorders who developed BD during follow-up. Data extraction, random-effects meta-analysis, between-study heterogeneity analysis, quality assessment, sub-group analyses, and meta-regressions were conducted.
Results
Thirty-nine studies were included, including 72,371 individuals (mean age=13.9 years, 57.1% females); 14.7% of C&A with a depressive disorder developed BD after 20.4–288 months: 9.5% developed BD-I (95% CI=4.7 to 18.1); 7.7% developed BD-II (95% CI=3.2% to 17.3%); 19.8% (95% CI=9.9% to 35.6%) of C&A admitted into the hospital with a depressive disorder developed BD. Studies using the DSM (21.6%, 95% CI=20.2% to 23.1%) and studies evaluating C&A with a major depressive disorder only (19.8%, 95% CI=16.8% to 23.1%) found higher rates of development of BD. Younger age at baseline, a history of hospitalization and recruitment from specialized clinics were associated with an increased risk of developing BD at follow-up. Quality of included studies was good in 76.9% of studies.
Conclusions
There is a substantial risk of developing BD in C&A with depressive disorders. This is particularly the case for C&A with MDD, DSM-diagnosed depressive disorders, and C&A admitted into the hospital. Research exploring additional predictors and preventive interventions is crucial.
Teenagers often present in crisis with risk issues, mainly risk to self but sometimes risk to others. Adolescent violence is commonplace and is not just the remit of adolescent forensic psychiatry. Clinicians may lack confidence assessing risk of violence and can neglect vital areas that are essential to reduce risk. Use of structured violence risk assessments enables the multi-agency professional network to formulate a young person's presentation and their violence in a holistic way and consequently develop targeted risk management plans addressing areas such as supervision, interventions and case management to reduce the risk of future violence. Of the several validated tools developed for young people, the Structured Assessment of Violence Risk – Youth (SAVRY™) is that most used by UK-based forensic adolescent clinicians. This article outlines the epidemiology, causes and purposes of violence among adolescents; discusses types of risk assessment tool; explores and deconstructs the SAVRY; and presents a fictitious risk formulation.
Providing alcohol screening and brief advice (SBA) in primary health care (PHC) can be an effective measure to reduce alcohol consumption. To aid successful implementation in an upper middle-income country context, this study investigates the perceived appropriateness of the programme and the perceived barriers to its implementation in PHC settings in three Latin American countries: Colombia, Mexico and Peru, as part of larger implementation study (SCALA).
Methods:
An online survey based on the Tailored Implementation for Chronic Diseases (TICD) implementation framework was disseminated in the three countries to key stakeholders with experience in the topic and/or setting (both health professionals and other roles, for example regional health administrators and national experts). In total, 55 respondents participated (66% response rate). For responses to both appropriateness and barriers questions, frequencies were computed, and country comparisons were made using Chi square and Kruskal–Wallis non-parametric tests.
Results:
Alcohol SBA was seen as an appropriate programme to reduce heavy alcohol use in PHC and a range of providers were considered suitable for its delivery, such as general practitioners, nurses, psychologists and social workers. Contextual factors such as patients’ normalised perception of their heavy drinking, lack of on-going support for providers, difficulty of accessing referral services and lenient alcohol control laws were the highest rated barriers. Country differences were found for two barriers: Peruvian respondents rated SBA guidelines as less clear than Mexican (Mann–Whitney U = −18.10, P = 0.001), and more strongly indicated lack of available screening instruments than Colombian (Mann–Whitney U = −12.82, P = 0.035) and Mexican respondents (Mann–Whitney U = −13.56, P = 0.018).
Conclusions:
The study shows the need to address contextual factors for successful implementation of SBA in practice. General congruence between the countries suggests that similar approaches can be used to encourage widespread implementation of SBA in all three studied countries, with minor tailoring based on the few country-specific barriers.
Registry-based trials have emerged as a potentially cost-saving study methodology. Early estimates of cost savings, however, conflated the benefits associated with registry utilisation and those associated with other aspects of pragmatic trial designs, which might not all be as broadly applicable. In this study, we sought to build a practical tool that investigators could use across disciplines to estimate the ranges of potential cost differences associated with implementing registry-based trials versus standard clinical trials.
Methods:
We built simulation Markov models to compare unique costs associated with data acquisition, cleaning, and linkage under a registry-based trial design versus a standard clinical trial. We conducted one-way, two-way, and probabilistic sensitivity analyses, varying study characteristics over broad ranges, to determine thresholds at which investigators might optimally select each trial design.
Results:
Registry-based trials were more cost effective than standard clinical trials 98.6% of the time. Data-related cost savings ranged from $4300 to $600,000 with variation in study characteristics. Cost differences were most reactive to the number of patients in a study, the number of data elements per patient available in a registry, and the speed with which research coordinators could manually abstract data. Registry incorporation resulted in cost savings when as few as 3768 independent data elements were available and when manual data abstraction took as little as 3.4 seconds per data field.
Conclusions:
Registries offer important resources for investigators. When available, their broad incorporation may help the scientific community reduce the costs of clinical investigation. We offer here a practical tool for investigators to assess potential costs savings.
Eating disorders are heterogeneous disorders characterised by a maladaptive drive to lose weight and, for the most part, by extreme fear of weight gain and overvaluation of thin body image. Calorie restriction, overexercise and purging behaviours put some sufferers at high risk of physical morbidity and mortality. Mental preoccupations interfere with social, professional and general quality of life. Patients’ defensive secrecy and compulsivity can make it hard to diagnose and treat such disorders despite the suffering they involve. Integrated medical and psychiatric intervention can save life and safely improve nutrition. Behavioural support – with family and carer involvement when appropriate – can counter the dysregulation that leads to vicious cycles of restriction–binge–purge, helping patients develop new skills to regulate emotion without weight losing. In the future, exciting developments in neuroimaging, neurosurgery and pharmacology may lead to ways to make the brain more responsive to therapy. Insights into risk factors may also improve preventive strategies in a climate of highly sophisticated international electronic communication.
On August 14, 2017, a 6-kilometer mudslide occurred in Regent Area, Western Area District of Sierra Leone following a torrential downpour that lasted 3 days. More than 300 houses along River Juba were submerged; 1141 people were reported dead or missing and 5905 displaced. In response to the mudslide, the World Health Organization (WHO) Country Office in Sierra Leone moved swiftly to verify the emergency and constitute an incident management team to coordinate the response. Early contact was made with the Ministry of Health and Sanitation and health sector partners. A Public Health Emergency Operations Center was set up to coordinate the response. Joint assessments, planning, and response among health sector partners ensured effectiveness and efficiency. Oral cholera vaccination was administered to high-risk populations to prevent a cholera outbreak. Surveillance for 4 waterborne diseases was enhanced through daily reporting from 9 health facilities serving the affected population. Performance standards from the WHO Emergency Response Framework were used to monitor the emergency response. An assessment of the country’s performance showed that the country’s response was well executed. To improve future response, we recommend enhanced district level preparedness, update of disaster response protocols, and pre-disaster mapping of health sector partners.
Recent years have seen an exponential increase in the variety of healthcare data captured across numerous sources. However, mechanisms to leverage these data sources to support scientific investigation have remained limited. In 2013 the Pediatric Heart Network (PHN), funded by the National Heart, Lung, and Blood Institute, developed the Integrated CARdiac Data and Outcomes (iCARD) Collaborative with the goals of leveraging available data sources to aid in efficiently planning and conducting PHN studies; supporting integration of PHN data with other sources to foster novel research otherwise not possible; and mentoring young investigators in these areas. This review describes lessons learned through the development of iCARD, initial efforts and scientific output, challenges, and future directions. This information can aid in the use and optimisation of data integration methodologies across other research networks and organisations.
This article is an output of a major research project examining the notion of imminence in the law on international protection. It is the first piece of scholarship to identify an emerging trend, namely the introduction of imminence—whether invoked implicitly or explicitly—as a potential barrier to refugee status or complementary protection. The article analyses the jurisprudence of relevant international bodies and courts and critiques the validity of this notion as a tool for assessing States’ protection obligations.
As the HIV population ages, how the ageing and HIV experiences intersect to shape the lives of older people living with HIV (PLWH) becomes an increasingly pressing question. This multi-method study investigated social support, mental health and quality of life among 100 older PLWH in the United Kingdom. Drawing on data from three focus groups and 74 life-history interviews with older (aged 50+) White men who have sex with men (MSM), and Black African and White heterosexual men and women, living with HIV, we explore participants’ distinctions between, evaluations of and access to sources of social support. Participants distinguished between support from the HIV-negative (Goffman's ‘the own’) and experientially based support from other PLWH (Goffman's ‘the wise’), and viewed the former, while valuable, as needing to be supplemented by the latter. Furthermore, access to experientially based support varied across participant groups, whose communities had different histories with HIV/AIDS and thus different degrees of knowledge about HIV and avenues for connecting to other PLWH. Thus, social support among older PLWH cannot be neatly divided into ‘formal’ and ‘informal’ domains, or fully appreciated by applying traditional social support measures, including, in the context of health conditions, ‘peer support’ created through formal service organisations. Rather, older PLWH's own distinctions and evaluations better illuminate the complexities of social support in the context of ageing with HIV.
This paper investigates the interaction between reality and imagination in the architectural design process. It engages with four inter-related inquiries. First, the interplay between reality and imagination in the architectural design process in student design-build live projects. Second, the interplay of reality and imagination for different agents in the architectural design process. Third, how the work of John Hejduk (1929-2000) enables a reappraisal of conceptions of reality and imagination in architectural design. Fourth, we address a live project for The Story Museum in Oxford, UK – a physical architectural space concerned with imaginary spaces – that suggests how an understanding of reality and imagination might be deepened in the architectural design process.
The text reappraises the interplay of reality and imagination in architectural design as a cognitive process. There are two aims: to reassess empirical responses and received wisdom about what is real and what is imagined in architectural design; and to reassess the perception of differences between imagination and reality occurring across education and practice. ‘Thing Theory’ is proposed as a conceptual framework which allows us to improve our understanding of how architectural designs emerge, are transformed in the designer's mind, how architects communicate them to others and how they are understood and shared by others. Reference is also made to interviews with prominent architects. The term ‘thing’ was repeatedly used by these architects to describe moments in the design process when a break from reality had occurred. In these moments, subject and object seemed at their most intertwined. This moment is strong because it is so flexible in responding to change and managing complexity. It is also weak because it is a time when the designer tends to neglect vital everyday constraints such as occupation and ethics. However, this is a key moment because it allows possible future realities to emerge.
To examine overall micronutrient intake periconceptionally and throughout pregnancy in a population-based cohort of Australian women.
Design
In a prospective cohort study, micronutrient dosages were extracted from self-reported maternal supplement use, recorded pre-conception, and for each trimester of pregnancy. A food frequency scale (DQESv2) captured usual maternal diet for gestational weeks 14–26. The influence of sociodemographic and lifestyle factors associated with supplement use was examined using logistic regression, and changes in micronutrient intakes prior to and throughout pregnancy were assessed using repeated-measures ANOVA analyses.
Setting
Metropolitan hospital sites in Melbourne, Australia.
Subjects
Women with a viable singleton pregnancy were recruited at less than 19 weeks’ gestation (n 2146).
Results
Compared with non-users, women using supplements during pregnancy were more likely to have planned their pregnancy, be >25 years old, primiparous, Caucasian, non-smokers, have a tertiary education and be consuming a folate-rich diet. Intakes of folate, Fe and Zn were significantly lower in the periconceptional period, compared with other periods (P<0·001). Intakes below Recommended Daily Intake levels were common both periconceptionally and throughout pregnancy, with 19–46 % of women not meeting the Recommended Daily Intake for folate, 68–82 % for Fe and 17–36 % for Zn. Conversely, 15–19 % of women consumed beyond the recommended Upper Limit for folate and 11–24 % for Fe.
Conclusions
The study highlights the need for improved public health education on nutritional needs during pregnancy, especially among women with lower educational achievements and income.
In this study, we used farm-level data from a university feed-out program to evaluate how the value of feeder cattle ultimately realized through finishing and grid pricing differs from their market value at public auction. Consistent with the theory of factor price disparity, results indicate that significant risk premiums exist in the feeder cattle market. Producers of cattle with known feedlot performance, carcass potential, or both might be better off retaining ownership of their calves or marketing them in a way that communicates the information that is known about their potential performance directly to the buyer.
Purpose: Traumatic brain injury (TBI) often leads to executive functions deficits, which may be responsible for severe and longstanding disabilities in everyday activities. Sensitivity and ecological validity of neuropsychological tests of executive functions have been questioned. The aims of this study were to pilot an ecological open-ended assessment of executive functions in children, the ‘Children's Cooking Task’ (CCT), specifically to report its reliability, discriminant validity and concurrent validity. Methods: Twenty-five children with mild (n = 10) or moderate-to-severe TBI (n = 15), and 21 matched controls (aged 8 to 20 years) participated in the study. An open-ended cooking task was designed to test multi-tasking abilities. It required the preparation of two simple recipes using specific instructions. Outcome measures included the number of errors and an overall qualitative analysis of the task. Validating measures of executive functions included the Delis Kaplan Executive Function System, the Six-Part Test and two questionnaires completed by the child's primary care-giver: the Behavior Rating Inventory of Executive Function and the Dysexecutive Questionnaire for Children. Results: Internal consistency of the Children's Cooking Task was high (Cronbach's alpha = .86), as was test–retest reliability (ICC = .89). Children with moderate-to-severe TBI, as well as children with mild TBI made significantly more errors in the Children's Cooking Task in comparison to controls (p < .001). The CCT was correlated with several tests and one questionnaire of executive functioning (Trails, verbal fluency, sorting, 20 questions, Dysexecutive Questionnaire). Discussion and Conclusion: The Children's Cooking Task has good interrater and test–retest reliability, as well as good discriminant and concurrent validity.
