What are the consequences of selective emigration from a closed regime? To answer this question, I focus on socialist East Germany and leverage an emigration reform in 1983 that led to the departure of about 65,200 citizens. Analyzing panel data on criminal activity in a difference-in-differences framework, I demonstrate that emigration can be a double-edged sword in contexts where it is restricted. Emigration after the reform had benefits in the short run and came with an initial decline in crime. However, it created new challenges for the regime as time passed. Although the number of ordinary crimes remained lower, border-related political crimes rose sharply in later years. Analysis of emigration-related petitioning links this result to a rise in demand for emigration after the initial emigration wave. These findings highlight the complexities of managing migration flows in autocracies and reveal a key repercussion of using emigration as a safety valve.
Having relevant indicator(s) of students’ school adjustment is the basis for making educational decisions with regard to an enormous scope of topics that refer to either individual students, a specific class, or even the entire school level. Thus, a major cornerstone in the effort to promote students’ school adjustment is the ability to correctly and accurately measure it. The problem of defining a given student’s state is a multi-aspect and multi-level challenge that is shaped by the local authorities’ guidelines, cultural norms, economic circumstances, and the student’s intellectual qualifications and personal characteristics. The existing literature suggests a rich list of measurements of the student’s feelings and the teacher’s evaluation of the student’s academic achievements, but parental and peer reflections are relatively underrepresented. This chapter advocates the priority of students’ subjective evaluations. Such measurements appear under various titles: students’ belonging, engagement, attitude, feelings, satisfaction, well-being, liking, burnout, sentiment, and more. In order to conduct routine evaluations of students’ school adjustment there is a need for a short and easily administered scale. For this end, the School Adjustment Questionnaire (SAQ) is presented as a possible example.
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.
In the UK, around 1 in 4 adults over 65 years suffers from depression. Depression case finding followed by alerting patients and their general practioners (GPs) (screening + GP) is a promising strategy to facilitate depression management, but its cost-effectiveness remains unclear.
Aims
To investigate the cost-effectiveness of screening + GP compared with standard of care (SoC) in northern England.
Method
Conducted alongside the CASCADE study, 1020 adults aged 65+ years were recruited. Participants with baseline Geriatric Depression Scale (GDS) ≥5 were allocated to the intervention arm and those >5 to SoC. Resource use and EQ-5D-5L data were collected at baseline and 6 months. Incremental cost-effectiveness ratio was calculated. Non-parametric bootstrapping was performed to capture sampling uncertainty. The results are presented using cost-effectiveness acceptability curves. Sensitivity analyses were conducted to assess the robustness of primary findings. Subgroup analyses were undertaken to examine the cost-effectiveness among participants with more comparable baseline characteristics across treatment groups.
Results
Screening + GP incurred £37 more costs and 0.006 fewer quality-adjusted life years than SoC; the probability of the former being cost-effective was <5% at a £30 000 cost-effectiveness threshold. Sensitivity analyses confirmed the base-case findings. Subgroup analyses indicated that screening + GP was cost-effective when patients with baseline GDS 2–7, 3–6 and 4–5, respectively, were analysed.
Conclusions
Screening + GP was dominated by SoC in northern England. However, subgroup analyses suggested it could be cost-effective if patients with more balanced baseline characteristics were analysed. Economic evaluations alongside randomised controlled trials are warranted to validate these findings.
In this chapter, we explore how electric and magnetic fields behave inside materials. The physics can be remarkably complicated and messy but the end result are described by a few, very minor, changes to the Maxwell equations. This allows us to understand various properties of materials, such as conductors.
A diagnostic label can have harms and benefits, particularly when provided following routine health screening tests. Whether these are discussed in clinical encounters is unknown.
Aims
To investigate whether potential impacts of diagnostic labelling are discussed before routine screening for non-cancer health conditions and explore the perceived value of such discussions by general practitioners (GPs) and healthcare consumers.
Method
Eleven semi-structured interviews with GPs and two focus groups with eight consumers were conducted. Interviews and focus groups were audio-recorded, transcribed and analysed using thematic analysis methods based on framework analysis.
Results
Prior to routine screening, most GPs did not discuss the potential consequences of diagnostic labelling, and no consumer recalled discussions of this nature. In contrast, many GPs provided information regarding the screening procedure and possible test limitations. Both GPs and consumers identified that it would be valuable to discuss the potential impacts of a diagnostic label; however, preferences varied as to the content and timing (i.e. before or after screening) of this discussion. Six themes that examine the utility of discussing the consequences of diagnostic labelling were identified: patient empowerment, patient variability, condition-specific information, GP and patient interactions and relationship, GP role and responsibilities, and characteristics of screening.
Conclusions
The practice and perceived value of discussing diagnostic labelling consequences were recognised as important by both GPs and consumers. However, preferences regarding the content of discussions and whether these occurred in clinical encounters before or after screening varied.
Many consultations in primary care involve patients with mental health problems, and primary care is typically the place where many such patients initially seek help. While considerable research has examined the prevalence of mental health disorders in primary care, relatively few papers have examined this issue in recent years. This study aims to address this gap by reviewing contemporary literature from 2014 to 2024 on the prevalence of mental health disorders among general practice patients.
Methods:
A comprehensive search across PubMed, PsycINFO, and Google Scholar was conducted, adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for article selection and assessment, examining the prevalence of mental health disorders in general practice.
Results:
Studies varied in methodologies and healthcare settings, with reported prevalence rates of mental health disorders ranging from 2.4% to 56.3%. Demographic characteristics (female gender, older age) were associated with a higher prevalence of mental health disorders in the studies identified. Studies based on patient interviews reported broader prevalence (2.4–56.3%) compared to studies using electronic medical record reviews (12–38%). Prevalence also varied between countries. Notably, there has been a lack of post-COVID-19 studies, especially within Europe, examining the prevalence of mental health prevalence in primary care.
Conclusions:
Mental health problems are still common among patients attending general practice; the approach to data collection (i.e., prospective interviews with patients), female gender and older age appear to be correlates of higher estimates. Further research involving a large-scale study with multiple sites is a priority.
This chapter considers questions of immigration institutional design in light of lessons learned from how Caribbean home-care aides currently work and travel. The growth in paid home care has been largely staffed by migrant labor – with some care workers operating outside of the scope of their visas. While these workers may technically be noncompliant, the author argues that most of these workers are in fact “good types,” who would have been favorably screened ex-ante for elder-care visas. The chapter proposes that we urgently devise a system that permits temporary entry of elder-care workers. If migrant care workers are permitted long-term temporary visas in which they can work in the US for a few months per year over several years, they have every incentive to comply.
This study aimed to refine the content of a new patient-reported outcome (PRO) measure via cognitive interviewing techniques to assess the unique presentation of depressive symptoms in older adults with cancer (OACs).
Methods
OACs (≥ 70years) with a history of a depressive disorder were administered a draft measure of the Older Adults with Cancer – Depression (OAC-D) Scale, then participated in a semi-structured cognitive interview to provide feedback on the appropriateness, comprehensibility, and overall acceptability of measure. Interviews were audio-recorded and transcribed, and qualitative methods guided revision of scale content and structure.
Results
OACs (N = 10) with a range of cancer diagnoses completed cognitive interviews. Participants felt that the draft measure took a reasonable amount of time to answer and was easily understandable. They favored having item prompts and response anchors repeated with each item for ease of completion, and they helped identify phrasing and wording of key terms consistent with the authors’ intended constructs. From this feedback, a revised version of the OAC-D was created.
Significance of results
The OAC-D Scale is the first PRO developed specifically for use with OACs. The use of expert and patient input and rigorous cognitive interviewing methods provides a conceptually accurate means of assessing the unique symptom experience of OACs with depression.
There has been an increasing number of applications from unaccompanied asylum-seeking children (UASC) in the United Kingdom in recent years. It is well-known that this population is at high-risk of developing mental health disorders, which require early detection and intervention to facilitate successful integration. This paper describes the introduction of mental health screening for unaccompanied asylum-seeking children in a National Health Service (NHS) outpatient clinic in central London. This follows the results of a two-year retrospective analysis of the health needs of the population in our clinic, which identified a high incidence of disturbance to mood and sleep. We describe the selection process for a culturally appropriate and validated screening tool, piloting the Refugee Health Screener (RHS) tool with 20 UASC in clinic, and using preliminary findings to inform a more targeted referral to community Child and Adolescent Mental Health Services (CAMHS). We conclude that implementation of the RHS-13 is feasible for widespread mental health screening for UASC in an NHS setting, and provide suggestions for future research directions within this field.
Screening for breast cancer using mammography is one of the most common medical tests for women aged 50 and older. In the United States, many protocols initiate mammography at ages 40 or 45. Although cancer screening tests are widely advocated, some systematic reviews find little evidence supporting the most common screening tests. Cancer screening clearly identifies lesions at an earlier stage. Yet, when evaluated against cancer-specific or all-cause mortality, screening is less likely to be associated with longer life of higher quality of life. This chapter reviews a series of biases, including lead time bias and length bias, that may explain the discrepancy between enthusiasm for cancer screening and clinical trials that have consistently failed to show benefit. We also review potential harms of screening, such as false positive results, unnecessary biopsies, and anxiety. We conclude that more studies are needed, particularly investigations that include a heterogeneous mix of studies participants.
Congenital heart Disease (CHD) is a significant cause of morbidity and mortality. Pulse-oximetry is a good non-invasive simple tool for critical CHD screening. Implications of this tool may be possible in certain areas and non-practical in others. We aim to report on the preliminary results of a recent ongoing protocol concerning the use of pulse-oximetry in detecting critical CHD in newborn in Egypt.
Patients & Methods:
All neonates born in or transferred to 10 university hospitals during the period between February and November 2023 and fulfilled the criteria of inclusion were screened for critical CHD by pulse-oximetry using Granelli protocol in the first 24–72 hours after birth.
Results:
During a 10-month pilot period, a total of 2392 neonates were screened. A total of 549 neonates (23%) tested positive (failed) screening. Among the positive cases, 213 neonates (42%) died during their hospital stay, while the remaining were discharged or scheduled for intervention. The positive cases underwent echocardiography that revealed CHD in the majority of cases (80.3%). Only 40 cases of those cases had cardiac defects that are classified as critical CHD with a prevalence of 16.7 per 1000 live births, while the rest of the cases have either simple (non-critical CHD) or persistent pulmonary hypertension. About 19.7% of positive cases have completely free echocardiograms without cardiac defects.
Conclusion:
The prevalence of critical CHD in Egypt is higher than the mean worldwide prevalence. The introduction of pulse-oximetry as a mass screening tool for critical CHD is possible and effective in low-income countries.
Tardive dyskinesia (TD) is a potentially irreversible movement disorder induced by dopamine receptor-blocking agents, including antipsychotics. Despite progress in antipsychotic medications, TD remains widely prevalent even in the era of second-generation antipsychotics. Early detection is critical for preventing irreversible damage and minimizing the disorder’s impact on patients’ daily lives. Risk factors for TD include advanced age, female sex, medical comorbidities, and prolonged use of dopamine receptor-blocking agents (DRBAs). Effective screening for TD should incorporate evidence-based screening techniques such as the Abnormal Involuntary Movement Scale (AIMS) and informal methods to capture a comprehensive view of TD’s severity and impact. Combining these approaches allows for a thorough assessment of both healthcare practitioner-perceived severity and patient-reported effects on daily life. Modern treatment options, including vesicular monoamine transporter 2 (VMAT2) inhibitors like valbenazine and deutetrabenazine, have demonstrated significant efficacy and safety in clinical trials. Approved by the FDA in 2017, these medications enable continued psychiatric care while managing TD symptoms. Long-term studies support their sustained efficacy and safety, underscoring the importance of individualized, evidence-based treatment plans to improve patient outcomes.
In low- and middle-income countries, fewer than 1 in 10 people with mental health conditions are estimated to be accurately diagnosed in primary care. This is despite more than 90 countries providing mental health training for primary healthcare workers in the past two decades. The lack of accurate diagnoses is a major bottleneck to reducing the global mental health treatment gap. In this commentary, we argue that current research practices are insufficient to generate the evidence needed to improve diagnostic accuracy. Research studies commonly determine accurate diagnosis by relying on self-report tools such as the Patient Health Questionnaire-9. This is problematic because self-report tools often overestimate prevalence, primarily due to their high rates of false positives. Moreover, nearly all studies on detection focus solely on depression, not taking into account the spectrum of conditions on which primary healthcare workers are being trained. Single condition self-report tools fail to discriminate among different types of mental health conditions, leading to a heterogeneous group of conditions masked under a single scale. As an alternative path forward, we propose improving research on diagnostic accuracy to better evaluate the reach of mental health service delivery in primary care. We recommend evaluating multiple conditions, statistically adjusting prevalence estimates generated from self-report tools, and consistently using structured clinical interviews as a gold standard. We propose clinically meaningful detection as ‘good-enough’ diagnoses incorporating multiple conditions accounting for context, health system and types of interventions available. Clinically meaningful identification can be operationalized differently across settings based on what level of diagnostic specificity is needed to select from available treatments. Rethinking research strategies to evaluate accuracy of diagnosis is vital to improve training, supervision and delivery of mental health services around the world.
Inference is considered for the marginal distribution of X, when (X, Y) has a truncated bivariate normal distribution. The Y variable is truncated, but only the X values are observed. The relationship of this distribution to Azzalini's “skew-normal” distribution is obtained. Method of moments and maximum likelihood estimation are compared for the three-parameter Azzalini distribution. Samples that are uniformative about the skewness of this distribution may occur, even for large n. Profile likelihood methods are employed to describe the uncertainty involved in parameter estimation. A sample of 87 Otis test scores is shown to be well-described by this model.
Studies show that people with severe mental illness (SMI) have a greater risk of dying from colorectal cancer (CRC). These studies mostly predate the introduction of national bowel cancer screening programmes (NBCSPs) and it is unknown if these have reduced disparity in CRC-related mortality for people with SMI.
Methods
We compared mortality rates following CRC diagnosis at colonoscopy between a nationally representative sample of people with and without SMI who participated in Australia’s NBCSP. Participation was defined as the return of a valid immunochemical faecal occult blood test (iFOBT). We also compared mortality rates between people with SMI who did and did not participate in the NBCSP. SMI was defined as receiving two or more Pharmaceutical Benefits Scheme prescriptions for second-generation antipsychotics or lithium.
Results
Amongst NBCSP participants, the incidence of CRC in the SMI cohort was lower than in the controls (hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.61–0.98). In spite of this, their all-cause mortality rate was 1.84 times higher (95% CI 1.12–3.03), although there was only weak evidence of a difference in CRC-specific mortality (HR 1.82; 95% CI 0.93–3.57). People with SMI who participated in the NBCSP had better all-cause survival than those who were invited to participate but did not return a valid iFOBT (HR 0.67, 95% CI 0.50–0.88). The benefit of participation was strongest for males with SMI and included improved all-cause and CRC-specific survival.
Conclusions
Participation in the NBCSP may be associated with improved survival following a CRC diagnosis for people with SMI, especially males, although they still experienced greater mortality than the general population. Approaches to improving CRC outcomes in people with SMI should include targeted screening, and increased awareness about the benefits or participation.

We evaluated the feasibility and acceptability of frailty screening using handgrip strength with gait speed measures within four primary care-based memory clinics in Ontario. This mixed methods quality improvement initiative examined the reach, effectiveness, adoption, implementation, and maintenance of frailty screening from the perspective of patients (N = 216), care partners (N = 142), and healthcare providers (N = 9). Frailty screening was well-received by patients and care partners and perceived as quick and easy to administer and integrate into assessment processes by healthcare providers at all four memory clinics. The ease of integrating frailty screening into clinic processes was a key factor facilitating implementation; few challenges or suggestions for improvement were identified. All four clinics plan to continue frailty screening, three using the methods adopted in this study. Integrating frailty screening into memory assessments is feasible and acceptable and, given the interactional relationship between frailty and dementia, provides a significant opportunity to improve health outcomes for older adults.
In the previous chapter we alluded to what is sometimes called ‘secondary’ prevention, where instead of trying to prevent disease from occurring, we try to detect it earlier, in the hope that this will enable more effective treatment and thus improved health outcomes. This is an aspect of public health that has great intuitive appeal, especially for serious conditions such as cancer, where the options for primary prevention can be very limited. However, screening programs are usually very costly exercises and they do not always deliver the expected benefits in terms of improved health outcomes. In this chapter we introduce you to the requirements for implementing a successful screening program and to some of the problems that we encounter when trying to determine whether such a program is actually beneficial in practice.
The avoidance of asthma triggers, like tobacco smoke, facilitates asthma management. Reliance upon caregiver report of their child’s environmental tobacco smoke (ETS) exposure may result in information bias and impaired asthma management. This analysis aimed to characterize the chronicity of ETS exposure, assess the validity of caregiver report of ETS exposure, and investigate the relationship between ETS exposure and asthma attack.
Methods:
A secondary data analysis was performed on data from a longitudinal study of 162 children aged 7–12 years with asthma living in federally subsidized housing in three US cities (Boston, Cincinnati, and New Orleans). Data were collected at three time points over 1 year.
Results:
Over 90% of children were exposed to ETS (≥0.25 ng/ml of urine cotinine (UC)). Exposure was consistent over 1 year. Questionnaire data had a sensitivity of 28–34% using UC ≥0.25 ng/ml as the gold standard. High ETS exposure (UC ≥ 30 ng/ml) was significantly associated with asthma attack (aOR 2.97, 0.93–9.52, p = 0.07). Lower levels (UC 0.25–30 ng/ml) were not statistically significant (aOR 1.76, 0.71– 4.38, p = 0.22). No association was found using caregiver-reported ETS exposure.
Conclusion:
Relying on questionnaire data to assess children’s exposure to tobacco smoke may lead to substantial information bias. For children with asthma, incorrect characterization may substantially impact asthma morbidity.
Guidelines recommend screening for psychiatric co-morbidities in patients with congenital heart defects alongside cardiac outpatient follow-ups. These recommendations are not implemented in Denmark. This study aimed to investigate the psychiatric co-morbidities in children and adolescents with Fontan circulation in Denmark and to evaluate the feasibility of an online screening measure for psychiatric disorders.
Methods:
Children, adolescents, and their families answered the Development and Well-Being Assessment questionnaire and a questionnaire about received help online. Development and Well-Being Assessment ratings present psychiatric diagnoses in accordance with ICD-10 and DSM-5. Parent-reported received psychiatric help is also presented. Feasibility data are reported as participation rate (completed Development and Well-Being Assessments) and parental/adolescent acceptability from the feasibility questionnaire.
Results:
The participation rate was 27%. Of the participating children and adolescents, 53% (ICD-10)/59% (DSM-5) met full diagnostic criteria for at least one psychiatric diagnosis. Of these, 50% had not received any psychiatric or psychological help. Only 12% of participants had an a priori psychiatric diagnosis.
Conclusions:
We found that a large proportion of children and adolescents with Fontan circulation are underdiagnosed and undertreated for psychiatric disorders. The results from our study emphasise the need for psychiatric screening in this patient group. Development and Well-Being Assessment may be too comprehensive for online electronic screening in children and adolescents with CHD.
