Psychosocial interventions are vital in treating severe mental illness, yet their use remains limited, and patients often lack adequate information about them. Patient-focused versions of clinical guidelines are designed to enhance mental health literacy and inform patients about available treatments, but these resources are underutilized. This study evaluated the impact of implementing a patient-focused psychosocial intervention guideline on empowerment, knowledge, and use of psychosocial interventions among individuals with severe mental illness.
Methods
Multicentre, cluster-randomised trial. The study population comprised adult patients with a severe mental disorder. The intervention group received a multimodal, structured, and protocol-led patient-focused guideline implementation, whereas the control group received treatment as usual. Data were analysed using hierarchical linear models. The primary outcome was the change in patients’ empowerment.
Results
There was no significant intervention effect on empowerment (effect size=0.13, p=0.605), which increased slightly in both groups. The number of psychosocial interventions familiar to patients increased significantly more in the intervention group. Exploratory analyses suggest that patient empowerment could have been influenced by COVID-19-related stress, patient age, the severity of functional impairment, and migration background. The improvement in the utilisation of psychosocial interventions did not differ significantly between the intervention group (M=1.1, SD=2.5) and the control group (M=1.3, SD=2.4).
Conclusions
The implementation of a patient-focused psychosocial intervention guideline failed to enhance empowerment among service users. However, our analyses indicate that the intervention led to an improvement in patient knowledge with respect to guideline content. The availability of psychosocial interventions may have been significantly constrained by the COVID-19 pandemic.
This article examines recent developments relating to the use of third-party findings of fact at the International Court of Justice (ICJ). A proliferation of fact-finding mechanisms creates more opportunities for litigants to ask the ICJ to rely on third-party facts. This demands renewed attention to how the ICJ responds to this type of evidence, especially given the rise of public interest litigation that may depend especially heavily on such materials. The analysis focuses on the ICJ’s approach in recent requests for the indication of provisional measures and asks whether the Court’s approach to third-party evidence differs depending on the phase of litigation, using the 2024 judgment in Ukraine v. Russia as a case study. Ultimately, recent decisions suggest that the ICJ’s efforts to distinguish evidence generated through an adversarial, court-like process from findings of fact based on investigation and fieldwork are often blurred in practice. Moreover, while the Court’s liberal approach to third-party evidence at the provisional measures phase may be justifiable, the quest for coherence in how the Court approaches third-party evidence, especially on the merits, remains a work in progress. To that end, the article suggests ways in which the Court could engage more closely with third-party fact-finding reports in the fulfillment of its adjudicatory function.
On July 19, 2024, the International Court of Justice (ICJ) rendered an advisory opinion on Legal Consequences Arising from the Policies and Practices of Israel in the Occupied Palestinian Territory, Including East Jerusalem. By votes of 11–4, the Court found that Israel's continued presence in the Occupied Palestinian Territory (OPT) was unlawful and needed to be ended as rapidly as possible. By a 14–1 majority, the Court also found that Israel was obligated to cease all new settlement activities, evacuate existing settlers from the OPT, and make reparation. The ICJ further opined by votes of 12–3 that all states and international organizations were obliged not to recognize as legal the situation arising from Israel's unlawful presence in the OPT, that all states must refrain from giving aid or assistance to the maintenance of that situation, and that the United Nations “should consider the precise modalities” required to bring Israel's unlawful presence in the OPT to an end.
Dropout from healthcare interventions can negatively affect patients and healthcare providers through impaired trust in the healthcare system and ineffective use of resources. Research on this topic is still largely missing on refugees and asylum seekers. The current study aimed to characterize predictors for dropout in the Mental Health in Refugees and Asylum Seekers (MEHIRA) study, one of the largest multicentered controlled trials investigating the effectiveness and cost-effectiveness of a nationwide stepped and collaborative care model.
Methods
Predictors were multiply imputed and selected for descriptive modelling using backward elimination. The final variable set was entered into logistic regression.
Results
The overall dropout rate was 41,7%. Dropout was higher in participants in group therapy (p = 0.001; OR = 10.7), with larger satisfaction with social relationships (p = 0.017; OR = 1.87), with difficulties in maintaining personal relationships (p = 0.005; OR = 4.27), and with higher depressive symptoms (p = 0.029; OR = 1.05). Participants living in refugee accommodation (p = 0.040; OR = 0.45), with a change in social status (p = 0.008; OR = 0.67) and with conduct (p = 0.020; OR = 0.24) and emotional problems (p = 0.013; OR = 0.31) were significantly less likely to drop out of treatment.
Conclusion
Overall, the outcomes of this study suggest that predictors assessing social relationships, social status, and living conditions should be considered as topics of psychological treatment to increase adherence and as predictors for future research studies (including treatment type).
In 2021, approximately 15,000 men in Germany died from prostate cancer (PCa). The national health policy is considering shifting from annual digital rectal examination (DRE)-based screening to an age-related prostate-specific antigen (PSA)-based risk-adapted and organized screening strategy. Our research investigated the cost–utility of the current DRE-based strategy versus organized age-related PSA-based risk-adaptive PCa screening strategies in Germany.
Methods
We adapted the Swedish Prostata model to the German context, recalibrating it with PCa clinical and epidemiological data from the national and state registries. The model includes preclinical and clinical disease health states defined by tumor, nodal, and metastatic stages and Gleason scores, and assumes that the benefits of screening arise from stage shift. We assessed the cost–utility of 14 strategies, ranging from no screening to DRE, and age-related, PSA-based, risk-adapted screening. Health state utility values and test characteristics were sourced from the literature. Inpatient and outpatient care costs were derived from the German diagnostic-related groups and uniform-based valuation systems.
Results
Among all strategies evaluated and compared with no screening, the “DRE only” strategy led to substantial overdiagnosis, the highest incremental cost, and minimal quality-adjusted life years (QALY) gains. PSA testing starting at 50 to 60 years with reflex MRI for PSA greater than 3 ng/mL cases followed by combined systemic and targeted biopsy reduced the number of biopsies and overdiagnosis by 75 percent and 26 percent, albeit for fewer QALYs and higher costs (dominated) than the same strategy without reflex MRI. The PSA-based risk-adaptive strategy, starting at 50 to 60 years without reflex MRI, demonstrated an 85 percent probability of being cost effective within the EUR30,000 (USD32,211) to EUR100,000 (USD107,369)/QALY willingness-to-pay range.
Conclusions
While Germany’s HTA emphasizes clinically added benefits and health-related quality of life, cost-effectiveness analysis substantiates this evidence. As a standalone early detection tool, DRE leads to substantial overdiagnosis, unnecessary biopsies, and increased healthcare costs. Overall, this study demonstrated the importance of age-related PSA risk-adaptive PCa screening. The value of MRI deserves further investigation, considering MRI’s positive effect on screening acceptability.
Parceling—using composites of observed variables as indicators for a common factor—strengthens loadings, but reduces the number of indicators. Factor indeterminacy is reduced when there are many observed variables per factor, and when loadings and factor correlations are strong. It is proven that parceling cannot reduce factor indeterminacy. In special cases where the ratio of loading to residual variance is the same for all items included in each parcel, factor indeterminacy is unaffected by parceling. Otherwise, parceling worsens factor indeterminacy. While factor indeterminacy does not affect the parameter estimates, standard errors, or fit indices associated with a factor model, it does create uncertainty, which endangers valid inference.
Apophyllite, a hydrous K-Ca-phyllosilicate, reacts with acidic aqueous solutions at room temperature. Various analytical methods have been applied to study the mechanism of the reaction and its characteristics, i.e. the changes in chemical composition, modifications in crystal structure and alterations in surface morphology. In contact with acidic solution, protonation of the terminal, non-bridging oxygen at the silicate tetrahedra takes place and the interlayer cations K+ and Ca2+ are removed. The protonation and ion removal causes the interlayer spacing to increase. Atomic force microscopy shows that the increase takes place discontinuously and, therefore, reflects a discontinuous reaction that comprises a two- or three-step protonation. Additionally, three structurally different protonation sites have been detected by nuclear magnetic resonance spectroscopy which also differ in the amount of close-by hydrogen, although in pristine apophyllite all terminal oxygen positions at silicate tetrahedra are structurally equivalent. In many clay minerals such structurally different protonation sites have not been detected so far. Thus, the multi-step protonation process in apophyllite clearly demonstrates the vast sensitivity of the protonation reaction on small structural variations in phyllosilicates.
Our limited knowledge of the climate prevailing over Europe during former glaciations is the main obstacle to reconstruct the past evolution of the ice coverage over the Alps by numerical modelling. To address this challenge, we perform a two-step modelling approach: First, a regional climate model is used to downscale the time slice simulations of a global earth system model in high resolution, leading to climate snapshots during the Last Glacial Maximum (LGM) and the Marine Isotope Stage 4 (MIS4). Second, we combine these snapshots and a climate signal proxy to build a transient climate over the last glacial period and force the Parallel Ice Sheet Model to simulate the dynamical evolution of glaciers in the Alps. The results show that the extent of modelled glaciers during the LGM agrees with several independent key geological imprints, including moraine-based maximal reconstructed glacial extents, known ice transfluences and trajectories of erratic boulders of known origin and deposition. Our results highlight the benefit of multiphysical coupled climate and glacier transient modelling over simpler approaches to help reconstruct paleo glacier fluctuations in agreement with traces they have left on the landscape.
Against the background of missing culturally sensitive mental health care services for refugees, we developed a group intervention (Empowerment) for refugees at level 3 within the stratified Stepped and Collaborative Care Model of the project Mental Health in Refugees and Asylum Seekers (MEHIRA). We aim to evaluate the effectiveness of the Empowerment group intervention with its focus on psychoeducation, stress management, and emotion regulation strategies in a culturally sensitive context for refugees with affective disorders compared to treatment-as-usual (TAU).
Method
At level 3 of the MEHIRA project, 149 refugees and asylum seekers with clinically relevant depressive symptoms were randomized to the Empowerment group intervention or TAU. Treatment comprised 16 therapy sessions conducted over 12 weeks. Effects were measured with the Patient Health Questionnaire-9 (PHQ-9) and the Montgomery–Åsberg Depression Rating Scale (MÅDRS). Further scales included assessed emotional distress, self-efficacy, resilience, and quality of life.
Results
Intention-to-treat analyses show significant cross-level interactions on both self-rated depressive symptoms (PHQ-9; F(1,147) = 13.32, p < 0.001) and clinician-rated depressive symptoms (MÅDRS; F(1,147) = 6.91, p = 0.01), indicating an improvement in depressive symptoms from baseline to post-intervention in the treatment group compared to the control group. The effect sizes for both scales were moderate (d = 0.68, 95% CI 0.21–1.15 for PHQ-9 and d = 0.51, 95% CI 0.04–0.99 for MÅDRS).
Conclusion
In the MEHIRA project comparing an SCCM approach versus TAU, the Empowerment group intervention at level 3 showed effectiveness for refugees with moderately severe depressive symptoms.
Refugees and asylum seekers (RAS) in Germany need tailored and resource-oriented mental healthcare interventions.
Aims
To evaluate the cost-effectiveness of group psychotherapy for RAS with moderate depressive symptoms.
Method
This is a post hoc cost-effectiveness analysis of Empowerment group psychotherapy that was embedded in a stratified stepped and collaborative care model (SCCM) from the multicentre randomised controlled MEHIRA trial. One hundred and forty-nine participants were randomly assigned to SCCM or treatment as usual (TAU) and underwent Empowerment (i.e. level 3 of the SCCM for adults) or TAU. Effects were measured with the nine-item Patient Health Questionnaire (PHQ-9) and quality adjusted life-years (QALY) post-intervention. Health service and intervention costs were measured. Incremental cost-effectiveness ratios (ICER) were estimated and net monetary benefit (NMB) regressions with 95% confidence intervals were performed. Cost-effectiveness was ascertained for different values of willingness to pay (WTP) using cost-effectiveness acceptability curves for probable scenarios. Trial registration number: NCT03109028 on ClinicalTrials.gov.
Results
Health service use costs were significantly lower for Empowerment than TAU after 1 year. Intervention costs were on average €409.6. Empowerment led to a significant change in PHQ-9 scores but not QALY. Bootstrapped mean ICER indicated cost-effectiveness according to PHQ-9 and varied considerably for QALY in the base case. NMB for a unit reduction in PHQ-9 score at WTP of €0 was €354.3 (€978.5 to −€269.9). Results were confirmed for different scenarios and varying WTP thresholds.
Conclusions
The Empowerment intervention was cost-effective in refugees with moderate depressive symptoms regarding the clinical outcome and led to a reduction in direct healthcare consumption. Concerning QALYs, there was a lack of confidence that Empowerment differed from TAU.
A theoretical and experimental framework for novel metamaterial with programmable damping properties is presented. This material system is able to switch between elastic-dominated and damping-dominated regimes with different overall stiffness under dynamic loading depending on the external stimulus. The unit cell combines an auxetic and a bellow-like layer separated by an interface through which the amount of media flow can be tuned depending on the lateral strain. A simplified analytical model is derived to analyse the programmable damping effect. The model is further extended with a fluid-dynamics approach to link the effective damping properties with geometrical parameters to aid with the practical design of the metamaterial. Afterward, experiments are conducted on a macroscopic level using laser-sintered unit cells to validate the functionality of the concept both with air and water as media within the unit cells. To conclude the work, initial results on microscopic-level unit cells fabricated by two-photon lithography are introduced to showcase the scalability of the concept. This work provides an experimentally validated theoretical framework for future investigations to design unit cells with programmable damping on different length scales for applications requiring tailored dynamic energy dissipation.
In a Nicaraguan population-based cohort, SARS-CoV-2 seroprevalence reached 28% in the first 6 months of the country's epidemic and reached 35% 6 months later. Immune waning was uncommon. Individuals with a seropositive household member were over three times as likely to be seropositive themselves, suggesting the importance of household transmission.
