Eight weeks of high-intensity interval training versus stretching do not change the psychoneuroendocrine response to a social stress test in emotionally impulsive humans

PURPOSE

Research supports physical activity as a method to heighten stress resistance and resilience through positive metabolic alterations mostly affecting the neuroendocrine system. High-intensity interval training (HIIT) has been proposed as a highly effective time-saving method to induce those changes. However, existing literature relies heavily on cross-sectional analyses, with few randomised controlled trials highlighting the necessity for more exercise interventions. Thus, this study aims to investigate the effects of HIIT versus an active control group on the stress response to an acute psychosocial stressor in emotionally impulsive humans (suggested as being strong stress responders).

METHODS

The study protocol was registered online (DRKS00016589) before data collection. Sedentary, emotionally impulsive adults (30.69 ± 8.20 y) were recruited for a supervised intervention of 8 weeks and randomly allocated to either a HIIT (n = 25) or a stretching group (n = 19, acting as active controls). Participants were submitted to a test battery, including saliva samples, questionnaires (self-efficacy- and perceived stress-related), visual analogue scales (physical exercise- and stress-related), and resting electroencephalography and electrocardiography assessing their reaction to an acute psychological stressor (Trier Social Stress Test) before and after the exercise intervention.

RESULTS

HIIT increased aerobic fitness in all participants, whereas stretching did not. Participants from the HIIT group reported perceiving exercising more intensively than those from the active control group (ƞp2 = 0.108, p = 0.038). No further group differences were detected. Both interventions largely increased levels of joy post-TSST (ƞp2 = 0.209, p = 0.003) whilst decreasing tension (ƞp2 = 0.262, p < 0.001) and worries (ƞp2 = 0.113, p = 0.037). Finally, both interventions largely increased perceived levels of general self-efficacy (ƞp2 = 0.120, p = 0.029).

CONCLUSION

This study suggests that 8 weeks of HIIT does not change the psychoneuroendocrine response to an acute psychological stress test compared to an active control group in emotionally impulsive humans. Further replications of supervised exercise studies highly powered with active and passive controls are warranted.

[Dysphagia in Parkinsonian Syndromes]

Dysphagia is a clinically relevant problem in Parkinson's disease as well as in atypical Parkinsonian syndromes, such as multiple system atrophy and diseases from the spectrum of 4‑repeat tauopathies, which affect most patients to a varying degree in the course of their disease. This results in relevant restrictions in daily life due to impaired intake of food, fluids, and medication with a subsequent reduction in quality of life. This article not only gives an overview of the pathophysiological causes of dysphagia in the various Parkinson syndromes, but also presents screening, diagnostic and treatment procedures that have been investigated for the different diseases.

Cu1.5SeyTe1-y (y = 0.2-0.7): A Series of Narrow Band Gap Semiconductors with Low Thermal Conductivity at Ambient Temperature

Coinage metal chalcogenides offer ideal prerequisites for high thermoelectric performance and sensor applications, with their usually low lattice thermal and high electrical conductivity, as well as small band gaps. In the solid solution Cu_1.5Se_yTe_1-y we synthesized phase pure materials with y = 0.2-0.7 and characterized them concerning selected physical properties. X-ray crystal structure determination was performed for two representatives of the solid solution, Cu_1.5Se_0.3Te_0.7 and Cu_1.5Se_0.5Te_0.5. The entire series crystallizes cubically, in space group Pm3̅n. No structural changes are observed between room temperature and the synthesis temperature of 723 K. The conductivity measurements and Seebeck coefficients of Cu_1.5Se_0.3Te_0.7 and Cu_1.5Se_0.5Te_0.5 indicate that the two representatives are narrow band gap semiconductors (E_g 0.06-0.08 eV). Both compounds show positive Seebeck coefficients and reasonably low thermal conductivities at moderate temperatures. Cu_1.5Se_0.5Te_0.5 is characterized by a bulk modulus of 40.9 GPa.

Clinical characteristics and outcome of patients with combined hepatocellular-cholangiocarcinoma-a European multicenter cohort

BACKGROUND

There is no clear consensus on the optimal systemic treatment regimen in combined hepatocellular-cholangiocarcinoma (cHCC-CCA) patients. We describe clinical characteristics and outcome of cHCC-CCA patients, with a special focus on patients receiving palliative systemic therapy, including immune checkpoint inhibitors (ICIs).

METHODS

In this European retrospective, multicenter study, patients with histologically proven cHCC-CCA treated at four institutions between April 2003 and June 2022 were included. In patients receiving palliative systemic therapy, outcome was compared between cytotoxic chemotherapy (CHT)- and non-cytotoxic CHT (nCHT)-treated patients.

RESULTS

Of 101 patients, the majority were male (n = 70, 69%) with a mean age of 64.6 ± 10.6 years. Only type of first-line treatment was independently associated with overall survival (OS). Palliative systemic therapy was administered to 44 (44%) patients. Of those, 25 (57%) patients received CHT and 19 (43%) had nCHT (n = 16 of them sorafenib) in systemic first line. Although there was no significant difference in overall response rate (ORR; CHT versus nCHT: 8% versus 5%), disease control rate (24% versus 21%), and median progression-free survival {3.0 months [95% confidence interval (CI) 1.4-4.6 months] versus 3.2 months (95% CI 2.8-3.6 months), P = 0.725}, there was a trend towards longer median OS in the CHT group [15.5 months (95% CI 8.0-23.0 months) versus 5.3 months (95% CI 0-12.5 months), P = 0.052]. However, in multivariable analysis, type of first-line regimen (CHT versus sorafenib) was not associated with OS. ORR in patients receiving ICIs (n = 7) was 29%.

CONCLUSIONS

In patients with cHCC-CCA, OS, progression-free survival, ORR, and disease control rate were not significantly different between individuals receiving CHT and patients receiving nCHT. Immunotherapy may be effective in a subset of patients. Prospective studies are needed to identify optimal systemic treatment regimens in cHCC-CCA.

A Switchable One-Compound Diode

A diode requires the combination of p- and n-type semiconductors or at least the defined formation of such areas within a given compound. This is a prerequisite for any IT application, energy conversion technology, and electronic semiconductor devices. Since the discovery of the pnp-switchable compound Ag₁₀ Te₄ Br₃ in 2009, it is in principle possible to fabricate a diode from a single material without adjusting the semiconduction type by a defined doping level. Often a structural phase transition accompanied by a dynamic change of charge carriers or a charge density wave within certain substructures are responsible for this effect. Unfortunately, the high pnp-switching temperature between 364 and 580 K hinders the application of this phenomenon in convenient devices. This effect is far removed from a suitable operation temperature at ambient conditions. Ag₁₈ Cu₃ Te₁₁ Cl₃  is a room temperature pnp-switching material and the first single-material position-independent diode. It shows the highest ever reported Seebeck coefficient drop that takes place within a few Kelvin. Combined with its low thermal conductivity, it offers great application potential within an accessible and applicable temperature window. Ag₁₈ Cu₃ Te₁₁ Cl₃ and pnp-switching materials have the potential for applications and processes where diodes, transistors, or any defined charge separation with junction formation are utilized.

Pan-tumor landscape of fibroblast growth factor receptor 1-4 genomic alterations

BACKGROUND

Selective tyrosine kinase inhibitors targeting fibroblast growth factor receptor (FGFR) 1-4 genomic alterations are in development or have been approved for FGFR-altered cancers (e.g. bladder cancer and advanced intrahepatic cholangiocarcinoma). Understanding FGFR inhibitor-resistance mechanisms is increasingly relevant; we surveyed the pan-tumor landscape of FGFR1-4 genomic alterations [short variants (SVs), gene rearrangements (REs), and copy number alterations (CNAs)], including their association with tumor mutational burden (TMB) and the genomic comutational landscape.

PATIENTS AND METHODS

Comprehensive genomic profiling of 355 813 solid tumor clinical cases was performed using the FoundationOne and FoundationOne CDx assays (Foundation Medicine, Inc.) to identify genomic alterations in >300 cancer-associated genes and TMB (determined on ≤1.1 megabases of sequenced DNA).

RESULTS

FGFR1-4 SVs and REs occurred in 9603/355 813 (2.7%), and CNAs in 15 078/355 813 (4.2%) samples. Most common FGFR alterations for bladder cancer, intrahepatic cholangiocarcinoma, and glioma were FGFR3 SVs (1051/7739, 13.6%), FGFR2 REs (618/6641, 9.3%), and FGFR1 SVs (239/11 550, 2.1%), respectively. We found several, potentially clinically relevant, tumor-specific associations between FGFR1-4 genomic alterations and other genomic markers. FGFR3 SV-altered bladder cancers and FGFR1 SV-altered gliomas were significantly less likely to be TMB-high versus unaltered samples. FGFR3 SVs in bladder cancer significantly co-occurred with TERT and CDKN2A/B alterations; TP53 and RB1 alterations were mutually exclusive. In intrahepatic cholangiocarcinoma, FGFR2 REs significantly co-occurred with BAP1 alterations, whereas KRAS, TP53, IDH1, and ARID1A alterations were mutually exclusive. FGFR1 SVs in gliomas significantly co-occurred with H3-3A and PTPN11 alterations, but were mutually exclusive with TERT, EGFR, TP53, and CDKN2A/B alterations.

CONCLUSIONS

Overall, our hypothesis-generating findings may help to stratify patients in clinical trials and guide optimal targeted therapy in those with FGFR alterations.

Prolonged grief in refugees living in Germany confronted with ambiguous or confirmed loss

BACKGROUND AND OBJECTIVES

People often disappear in the context of displacement or armed conflicts. Although such an ambiguous loss is accompanied by persistent uncertainty about the whereabouts, the psychological consequences are not well understood. This study investigated the effects of ambiguous compared to a confirmed loss on prolonged grief disorder (PGD) and its correlates in refugees to Germany.

METHODS AND DESIGN

We investigated data on mental health outcomes of refugees from Syria, Iraq, Iran and Afghanistan who had applied for/were granted asylum in Germany. In a secondary analysis, we compared 87 refugees with disappeared (n = 33) and deceased relatives (n = 54) who had completed questionnaire-based interviews.

RESULTS

Participants with ambiguous loss displayed more severe symptoms of PGD than those with confirmed loss. However, we found no group differences in terms of probable disorder rates and the number of traumatic experiences. Even after controlling for several correlates of PGD, higher PGD symptom severity was associated with ambiguous loss, more PTSD symptoms and low perceived social support.

CONCLUSIONS

These results show a higher prolonged grief symptom severity after the loss of a significant other due to disappearance, indicating that this type of loss could be a specific risk factor for PGD severity.

Same name, same content? Evaluation of DSM-5-TR and ICD-11 prolonged grief criteria

OBJECTIVE

Investigating the concordance of prolonged grief disorder (PGD) criteria that have been recently introduced to the 5th text revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) and the International Classification of Diseases 11th Revision (ICD-11).

METHOD

N = 193 treatment-seeking bereaved adults were assessed with the prolonged grief disorder 13 + 9 interview. Data were examined in terms of (a) diagnostic rates for PGDDSM-5-TR and PGDICD-11, including increases of the PGDICD-11 accessory symptom threshold (PGDICD-11-X+) and time criterion (PGDICD-11-12 months), (b) dimensionality, (c) the frequency with which single PGD symptoms occur, and (d) concurrent validity in terms of psychological symptoms and loss-related characteristics.

RESULTS

The diagnostic rate of PGDDSM-5-TR (52%) was significantly lower than that of PGDICD-11 (76%) and agreement between the two criteria sets was moderate, κ = 0.51, 95% CI [0.47-0.55]. Increasing the PGDICD-11 accessory symptom threshold did not improve the diagnostic agreement. In contrast, increasing the ICD-11 time criterion led to almost perfect agreement between PGDICD-11-12 months and PGDDSM-5-TR, κ = 0.91, 95% CI [0.89-0.93]. Confirmatory factor analysis results indicated a one-factor model fit best for both PGDDSM-5-TR and PGDICD-11. Emotional pain symptoms (e.g., guilt) were predominantly reported by patients with a PGDICD-11 diagnosis, while attachment disturbance symptoms (e.g., identity disruption) were reported more often by patients with a PGDDSM-5-TR diagnosis.

CONCLUSIONS

Despite methodological limitations of this study, results indicate discordance in PGDDSM-5-TR and PGDICD-11 regarding diagnostic rates and single symptom occurrence, while the factor structure is similar. Changes in the ICD-11 time criterion could reduce these differences. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Predictors of Prolonged Grief Disorder in a German Representative Population Sample: Unexpectedness of Bereavement Contributes to Grief Severity and Prolonged Grief Disorder

Most people adapt to bereavement over time. For a minority, the grief persists and may lead to a prolonged grief disorder (PGD). Identifying grievers at risk of PGD may enable specific prevention measures. The present study examined the extent to which the subjective unexpectedness of the death predicted grief outcomes above and beyond known sociodemographic and objective loss-related variables in a sample drawn from a population-representative investigation. In our sample (n = 2,531), 811 participants (M _age 55.1 ± 17.8 years, 59.2% women) had experienced the loss of a significant person six or more months ago. Participants provided demographic and loss-related information, perceptions of the unexpectedness of the death and completed the Prolonged Grief Disorder-13 + 9 (PG-13 + 9). The PG-13 + 9 was used to determine PGD caseness. A binary logistic regression investigated predictors of PGD caseness, and a linear regression predictors of grief severity. ANCOVAs compared PGD symptoms between the groups who had experienced an "expected" vs. "unexpected" loss, while controlling for the relationship to the deceased and time since loss. The loss of a child (OR = 23.66; 95%CI, 6.03-68.28), or a partner (OR = 5.32; 95%CI, 1.79-15.83), the time since loss (OR = 0.99; 95%CI, 0.99-1.00) and the unexpectedness of the death (OR = 3.58; 95%CI, 1.70-7.69) were significant predictors of PGD caseness (Nagelkerke's R² = 0.25) and grief severity. Participants who had experienced the loss as unexpected (vs. expected) reported higher scores on all PGD symptoms. Unexpectedness of the death emerged as significant risk factor for PGD, even after controlling for demographic and other loss-related variables. While our findings replicate previous research on the importance of the relationship to the deceased as a risk factor for PGD, they also highlight the importance of assessing the subjective unexpectedness of a death and may help to identify risk groups who can profit from preventive interventions.

Introduction and evaluation of a therapeutic adherence and competence scale for grief-focused cognitive behavioural therapy

BACKGROUND

There is no therapeutic competence and adherence scale for grief-focused cognitive behavioural therapy (grief-focused CBT). However, given the growing body of evidence for the efficacy of grief-focused CBT, such a scale is needed both to ensure the internal validity of clinical trials and to facilitate psychotherapy process research.

OBJECTIVE

To develop and undertake a psychometric evaluation of a therapeutic adherence and competence scale for grief-focused CBT.

METHOD

The scale was developed in two steps. (I) Five experts on the treatment of prolonged grief disorder provided feedback on the relevance and appropriateness of the items. The scale was revised to reflect their feedback. The final therapeutic adherence and competence scale for grief (TACs-G) consisted of 15 adherence and 16 competence items. (II) Psychometric evaluation of the TACs-G was based on the rating of 48 randomly selected PG-CBT sessions by two independent raters. The videos were recorded in the context of a randomized controlled trial (RCT; DRKS00012317.) ICC was used to calculate inter-rater reliability and TACs-G stability over time (re-evaluation of 10 sessions after 12 months).

RESULTS

The five experts confirmed the relevance and appropriateness of the items. Interrater reliability was found to be high for the total adherence and competence scores (ICC = 0.889 and 0.782, respectively) and moderate to excellent for individual items (ICC = 0.509-1.00). The TACs-G stability over time was found to be strong for both adherence (ICC = 0.970) and competence total scores (ICC = 0.965).

CONCLUSIONS

The TACs-G for CBT is a reliable instrument that can be used not only to ensure internal validity but is also suited for psychotherapy process studies. Additionally, it provides a valuable database for targeted feedback in training settings.

HIGHLIGHTS

This is the first study to report on the development and psychometrical evaluation of a grief-focused adherence and competence scale.Although an increasing number of clinical trials do report the efficacy of grief-focused cognitive-behavioural therapy, none of these studies used a standardized adherence and competence scale to control internal validity.In the present study, we introduced a therapeutic adherence and competence scale for grief (TACs-G) that can be applied efficiently across different research settings (e.g. manipulation check, dissemination), and report results of good to excellent psychometric properties.The scale itself could prove useful beyond the research setting as it could possibly serve as a basis for feedback in training settings.

Rationale and design of the CRAFT (Continuous ReAssessment with Flexible ExTension in Rare Malignancies) multicenter phase II trial

BACKGROUND

Approvals of cancer therapeutics are primarily disease entity specific. Current molecular diagnostic approaches frequently identify actionable alterations in rare cancers or rare subtypes of common cancers for which the corresponding treatments are not approved and unavailable within clinical trials due to entity-related eligibility criteria. Access may be negotiated with health insurances. However, approval rates vary, and critical information required for a scientific evaluation of treatment-associated risks and benefits is not systematically collected. Thus clinical trials with optimized patient selection and comprehensive molecular characterization are essential for translating experimental treatments into standard care.

PATIENTS AND METHODS

Continuous ReAssessment with Flexible ExTension in Rare Malignancies (CRAFT) is an open-label phase II trial for adults with pretreated, locally advanced, or metastatic solid tumors. Based on the evaluation by a molecular tumor board, patients are assigned to combinations of six molecularly targeted agents and a programmed death-ligand 1 (PD-L1) antagonist within seven study arms focusing on (i) BRAF V600 mutations; (ii) ERBB2 amplification and/or overexpression, activating ERBB2 mutations; (iii) ALK rearrangements, activating ALK mutations; (iv and v) activating PIK3CA and AKT mutations, other aberrations predicting increased PI3K-AKT pathway activity; (vi) aberrations predicting increased RAF-MEK-ERK pathway activity; (vii) high tumor mutational burden and other alterations predicting sensitivity to PD-L1 inhibition. The primary endpoint is the disease control rate (DCR) at week 16; secondary and exploratory endpoints include the progression-free survival ratio, overall survival, and patient-reported outcomes. Using Simon's optimal two-stage design, 14 patients are accrued for each study arm. If three or fewer patients achieve disease control, the study arm is stopped. Otherwise, 11 additional patients are accrued. If the DCR exceeds 7 of 25 patients, the null hypothesis is rejected for the respective study arm.

CONCLUSIONS

CRAFT was activated in October 2021 and will recruit at 10 centers in Germany.

Ion Dynamics and Polymorphism in Cu20Te11Cl3

Coinage metal polychalcogenide halides are an intriguing class of materials, and many representatives are solid ion conductors and thermoelectric materials. The materials show high ion mobility, polymorphism, and various attractive interactions in the cation and anion substructures. Especially the latter feature leads to complex electronic structures and the occurrence of charge-density waves (CDWs) and, as a result, the first p-n-p switching materials. During our systematic investigations for new p-n-n switching materials in the Cu-Te-Cl phase diagram, we were able to isolate polymorphic Cu₂₀Te₁₁Cl₃, which we characterized structurally and with regard to its electronic and thermoelectric properties. Cu₂₀Te₁₁Cl₃ is trimorphic, with phase transitions occurring at 288 and 450 K. The crystal structures of two polymorphs, the α phase, stable above 450 K, and the β polymorph (288-450 K), are reported, and the complex structure chemistry featuring twinning upon a phase change is illustrated. We identified a dynamic cation substructure and a static anion substructure for all polymorphs, characterizing Cu₂₀Te₁₁Cl₃ as a solid Cu-ion conductor. Temperature-dependent measurements of the Seebeck coefficient and total conductivity were performed and substantiated a linear response of the Seebeck coefficient, a lack of CDWs, and no p-n-p switching. Reasons for a lack of CDWs in Cu₂₀Te₁₁Cl₃ are discussed and illustrated in the context of existing p-n-p switching materials.

Ultrafast Photoconductivity and Terahertz Vibrational Dynamics in Double-Helix SnIP Nanowires

Tin iodide phosphide (SnIP), an inorganic double-helix material, is a quasi-1D van der Waals semiconductor that shows promise in photocatalysis and flexible electronics. However, the understanding of the fundamental photophysics and charge transport dynamics of this new material is limited. Here, time-resolved terahertz (THz) spectroscopy is used to probe the transient photoconductivity of SnIP nanowire films and measure the carrier mobility. With insight into the highly anisotropic electronic structure from quantum chemical calculations, an electron mobility as high as 280 cm²   V^-1 s^-1 along the double-helix axis and a hole mobility of 238 cm²   V^-1 s^-1 perpendicular to the double-helix axis are detected. Additionally, infrared-active (IR-active) THz vibrational modes are measured, which shows excellent agreement with first-principles calculations, and an ultrafast photoexcitation-induced charge redistribution is observed that reduces the amplitude of a twisting mode of the outer SnI helix on picosecond timescales. Finally, it is shown that the carrier lifetime and mobility are limited by a trap density greater than 10¹⁸  cm^-3 . The results provide insight into the optical excitation and relaxation pathways of SnIP and demonstrate a remarkably high carrier mobility for such a soft and flexible material, suggesting that it could be ideally suited for flexible electronics applications.

Routineversorgung für Jugendliche und junge Erwachsene mit Posttraumatischer Belastungsstörung nach sexualisierter und physischer Gewalt in Deutschland

Zusammenfassung. Theoretischer Hintergrund: Für die Behandlung der Posttraumatischen Belastungsstörung (PTBS) im Jugend- und jungen Erwachsenenalter liegen diverse evidenzbasierte Interventionen (EBIs) vor. Fragestellung: Inwiefern sind EBIs für Jugendliche und junge Erwachsene mit PTBS nach sexualisierter und physischer Gewalt in Deutschland verfügbar? Methode: Es wurden die Daten von 39 Teilnehmenden einer multizentrischen Behandlungsstudie analysiert, die für die Diagnose einer PTBS ambulante Behandlungsempfehlungen erhalten hatten. Ergebnisse: In den folgenden sieben Monaten erhielten 21 der Teilnehmenden eine Behandlung; bei nur acht wurden in deren Rahmen die traumatischen Erfahrungen adressiert. Alle Teilnehmenden verbesserten sich hinsichtlich der PTBS-Symptomatik unabhängig von der Art der Behandlung. Diskussion und Schlussfolgerung: Die Ergebnisse weisen auf Barrieren für den Zugang zu EBIs in unserer Stichprobe hin. Künftige Forschung sollte die Hintergründe für diese Barrieren fokussieren.

Lost in Transition? Evidence-Based Treatments for Adolescents and Young Adults with Posttraumatic Stress Disorder and Results of an Uncontrolled Feasibility Trial Evaluating Cognitive Processing Therapy

Posttraumatic stress disorder (PTSD) is not uncommon among adolescents and young adults (AYAs). Left untreated, transition to adulthood might be especially challenging and/or prolonged for AYAs. However, it is unclear whether AYAs are adequately represented in current PTSD treatment research and whether they benefit to the same degree as younger or older individuals. In the first part of the paper, we reflect on developmental considerations in the treatment of AYAs and give an overview of current age-specific results in PTSD treatment research. Furthermore, we review individual trauma-focused evidence-based treatments that were examined in AYAs over the last 10 years. In the second part, we present data from an uncontrolled feasibility trial evaluating cognitive processing therapy (CPT) with some age-adapted modifications and an exposure component (written accounts). We treated 17 AYAs (aged 14 to 21) suffering from posttraumatic stress symptoms (PTSS). At posttreatment, participants had improved significantly with respect to clinician-rated PTSS severity (d = 1.32). Treatment gains were maintained throughout the 6-week and 6-month follow-ups. Results indicated that CPT, with only minor adaptations, was feasible and safe in AYAs. The recommendations for future research focus on the inclusion of young adults in trials with adolescents, more refined age reporting in clinical trials, and the encouragement of dismantling studies in youth. To conclude, clinical recommendations for caregiver involvement and the addressing of developmental tasks, motivational issues and emotion regulation problems are discussed.

Prevalence of prolonged grief disorder

BACKGROUND

Prolonged grief is a disorder (PGD) characterized by severe and disabling grief reactions for an extended period of time after the loss of a significant person. ICD-11 and DSM-5-TR differ substantially in individual criteria.

OBJECTIVE

Estimation of the respective prevalence of PGD_ICD-11 and PGD_DSM-5-TR and the frequency with which single symptoms of prolonged grief occur in the general population.

METHODS

Out of a representative sample of the German general population (N=2498), n = 914 reported a significant loss and prolonged grief symptoms based on the extended version of the self-reported Prolonged Grief Disorder-13+9 (PG13+9). Sociodemographic and loss-related characteristics were collected.

RESULTS

The probable prevalence of PGD_ICD-11 was 1.5% and that of PGD_DSM-5-TR was 1.2% in the general sample. Among bereaved persons (n=914), the prevalence of developing PGD_ICD-11 was 4.2% and that of PGD_DSM-5-TR was 3.3%. Diagnostic agreement between the two criteria-sets was very high and did not increase after heightening the accessory symptom threshold for PGD_ICD-11. Difficulties accepting the loss was the most frequent single symptom (14-25%) and grief-related impairment was common (10-16%). Over 60% of participants with a probable PGD diagnosis utilized health care services.

LIMITATIONS

Results are based on self-reported data. The PG13+9 was not designed to assess grief symptoms according to ICD-11 and DSM-5-TR diagnostic criteria.

CONCLUSIONS

Prolonged grief according to ICD-11 and DSM-5-TR is a notable disorder in the general population. Among bereaved persons, single symptoms of prolonged grief are relatively frequent and cause substantial degrees of impairment.

Disinfection of gloved hands during routine care

Healthcare-associated infections are a major issue in public health. After several decades of hand hygiene programmes, it is time to admit that we have failed to achieve our goal. One of the reasons is the overuse of gloves, which is in part justified by the nature of the nursing care. Several experimental studies supported the effectiveness of disinfecting gloves, but evidence for routine feasibility and effectiveness is lacking. The aim of this study was to evaluate the effectiveness of alcohol-based disinfection of gloves during nursing care. Swabs were taken from the most contaminated part of both hands at different times: T0 (before wearing gloves), T10 (after 10 minutes of nursing care) from both gloves, T10A (just after the gloves were disinfected for 30 seconds with bedside disposable hydroalcoholic solution) and when possible at T20 and T20A. After 10 minutes of nursing care, gloves were contaminated in 72.5% of cases. After alcohol-based disinfection, gloves became free of microorganism in 79.3% of cases. Alcohol-based disinfection of gloves during routine care is effective and appears to be a reasonable alternative to current recommendations.

Response of young patients with probable ICD-11 complex PTSD to treatment with developmentally adapted cognitive processing therapy

Background: ICD-11 features Complex Posttraumatic Stress Disorder (CPTSD) as a new diagnosis. To date, very few studies have investigated CPTSD in young patients, and there is a need for evidence on effective treatment. Objective: The present study evaluates the applicability of developmentally adapted cognitive processing therapy (D-CPT) for CPTSD in young patients in a secondary analysis of the treatment condition of a randomized controlled trial (RCT) investigating the efficacy of D-CPT. Methods: The D-CPT treatment group in the original study included 44 patients (14-21 years) with DSM-IV PTSD after childhood abuse. We used the ICD-11 algorithm to divide the sample into a probable CPTSD and a non-CPTSD group. We performed multilevel models for interviewer-rated and self-rated PTSD symptoms with fixed effects of group (CPTSD, non-CPTSD) and time (up to 12 months follow-up) and their interaction. Treatment response rates for both groups were calculated. Results: Nineteen (43.2%) patients fulfilled criteria for probable ICD-11 CPTSD while 25 (56.8%) did not. Both CPTSD and non-CPTSD groups showed symptom reduction over time. The CPTSD group reported higher symptom severity before and after treatment. Linear improvement and treatment response rates were similar for both groups. D-CPT reduced symptoms of disturbances in self-regulation in both groups. Discussion: Both, patients with and without probable ICD-11 CPTSD seemed to benefit from D-CPT and the treatment also reduced disturbances in self-regulation. Conclusion: This study presents initial evidence of the applicability of D-CPT in clinical practice for young patients with CPTSD. It remains debatable whether CPTSD implies different treatment needs as opposed to PTSD.

Feasibility of Present-Centered Therapy for Prolonged Grief Disorder: Results of a Pilot Study

Present-centered therapy (PCT) was originally developed as a strong comparator for the non-specific effects of psychotherapy in the treatment of posttraumatic stress disorder. PCT qualifies as a not strictly supportive treatment as it is structured and homework is assigned between sessions. It does not focus on cognitive restructuring or exposure. A growing body of literature supports its beneficial effects. For example, it demonstrated only slightly inferior effect sizes and lower dropout rates compared to that of trauma-focused cognitive behavioral therapy in several trials with patients suffering from posttraumatic stress disorder. The current study is the first to evaluate the feasibility and the treatment effects of PCT in adults with prolonged grief disorder (PGD). Meta-analyses on psychotherapy for PGD have yielded moderate effect sizes. N = 20 individuals suffering from PGD were treated with PCT by novice therapists as part of a preparation phase for an upcoming RCT in an outpatient setting. Treatment consisted of 20-24 sessions á 50 min. All outcomes were assessed before treatment, at post-treatment, and at the 3-month follow-up. The primary outcome, PGD symptom severity, was assessed using the Interview for Prolonged Grief-13. Secondary outcomes were self-reported PGD severity, depression, general psychological distress, and somatic symptom severity. Furthermore, therapists evaluated their experiences with their first PCT patient and the treatment manual. In intent-to-treat analyses of all patients we found a significant decrease in interview-based PGD symptom severity at post-treatment (d = 1.26). Decreases were maintained up to the 3-month follow-up assessment (d = 1.25). There were also significant decreases in self-reported PGD symptoms, depression, and general psychological distress. No changes were observed for somatic symptoms. The completion rate was 85%. Therapists deemed PCT to be a learnable treatment program that can be adapted to the patient's individual needs. The preliminary results of PCT as a treatment for PGD demonstrate large effects and indicate good feasibility in outpatient settings. The treatment effects were larger than those reported in meta-analyses. Thus, PCT is a promising treatment for PGD. Possible future research directions are discussed.
