OBJECTIVE Cough-inducing agents are used to study the cough reflex in both pharmacological and physiological research. Clinical use of cough challenge testing as a tool in diagnostic algorithms has been limited by the lack of either uniform methodology or reference values for healthy subjects. The objective of this study was to determine the cough threshold for capsaicin in a sample of healthy subjects, while also evaluating the influence of age, sex and smoking. We also assessed the reliability and repeatability of the test. MATERIAL AND METHODS Ninety-two healthy subjects were enrolled and given a capsaicin challenge test using concentrations from 0.49 to 500mg. The concentrations of capsaicin that triggered two and five coughs, C2 and C5 respectively, were recorded. The test was repeated three days later in a sub-sample of 30 subjects. RESULTS No subject showed clinical or functional signs of bronchoconstriction. The mean values obtained for the study population were log C2:1.5 +/- 0.69 mM. and log C5: 2.1 +/- 0.4 microM. The geometric means were 31.6 and 134.8 microM for C2 and C5, respectively. No significant differences were found for sex or smoking; however age was significantly related to log C5 (r: -0.27, p < 0.05). Repeatability of the capsaicin test was high, with intra-class correlation coefficients and 95% confidence intervals of 0.75 (0.53-0.87) and 0.88 (0.76-0.97)for C2 and C5, respectively. CONCLUSION The capsaicin challenge test was safe and easy to administer,gave reproducible results and allowed us to obtain reference values for a healthy population in our community.

- Abstract
Background: Mental health settings are increasingly using co-facilitation of educational group interventions in collaboration with patient partners and service users. However, despite promising results, limited information is available regarding the feasibility and satisfaction levels of these programmes among adults newly diagnosed with attention-deficit hyperactivity/impulsivity disorder (ADHD). Hence, this study aimed to determine the feasibility, acceptability, and preliminary effects of a user co-facilitated psychoeducational group programme for adults diagnosed with ADHD., Methods: This feasibility proof-of-concept randomised controlled trial recruited outpatients from a Norwegian community mental health centre. Outpatients randomised to the intervention group (IG) received a psychoeducational programme supplementing Treatment As Usual (TAU), while the control group received TAU. Feasibility was determined by the acceptance rate, adherence rate, and dropout rate. Acceptability was measured with the Client Satisfaction Questionnaire and a 3-item scale measuring satisfaction with the received information. To test the preliminary effects, self-efficacy, symptom severity, and quality of life were measured at baseline and pre- and post-intervention., Results: Feasibility was demonstrated; most of the patients were willing to enrol, participants attended 82% of the psychoeducational programme, and only 13% dropped out of the study. The between-group analyses revealed that the IG reported significantly greater mean satisfaction than the CG. Moreover, the intervention group was more satisfied with the information they received during the psychoeducational programme. Concerning the preliminary effects, the linear mixed model showed improvement in quality of life (the subscale relationship); however, other patient-reported outcomes did not show improvements., Conclusions: This proof-of-concept randomised controlled trial supports the feasibility and acceptability of the user co-facilitated psychoeducational programme for patients newly diagnosed with ADHD in an outpatient setting. While preliminary findings indicate promise in enhancing patient-reported outcomes, a larger study is warranted to assess the intervention's effectiveness rigorously., Trial Registration: NCT03425, 09/11/2017., (© 2024.

- Abstract
Introduction: Although psychoeducational group interventions are increasingly used for adults diagnosed with attention-deficit/hyperactivity disorder (ADHD), a comprehensive review focused on the feasibility and acceptability indicators of these interventions remains lacking. Furthermore, although previous research has explored various aspects of psychoeducation for ADHD, such as its definition and approaches, limited research has focused on the synthesis for outcome measures and patients' experiences related to these interventions. Therefore, this scoping review aims to map the existing evidence reported on psychoeducational group interventions for adults diagnosed with ADHD. The objective is to provide a comprehensive overview of feasibility indicators, acceptability, and outcome measures used in psychoeducational group interventions., Method: A comprehensive structured literature search on the topic was performed in seven bibliographic databases, and the resulting records were independently screened, and their data extracted by two reviewers. We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-S) to ensure the transparency and rigor of this scoping review., Results: The searches yielded 7510 records. Eight studies met the inclusion criteria. These included studies were conducted in European countries and the United States. Among these, six studies used a randomized control design, one an open feasibility trial, and one a pre-post intervention design. All the studies reported some feasibility and acceptability indicators. While all the studies reported on the severity of symptoms of ADHD as an outcome measure, some also reported on outcomes related to psychological or mental-health problems, quality of life, changes in knowledge regarding ADHD, or the level of self-esteem, functioning, and impairment., Conclusion: This scoping review revealed that psychoeducational group interventions are generally acceptable for patients in terms of patient satisfaction with the group intervention. All included studies reported some feasibility indicators, with some reporting good attendance and relatively low dropout rates. Most studies reported positive effects on ADHD and mental health symptoms, suggesting that these interventions are beneficial for adults with ADHD. However, several gaps exist regarding the reporting on the feasibility indicators, acceptability, and outcome measures employed across studies., (© 2024. The Author(s).)

- Abstract
Background: Psychosocial interventions such as psychoeducation are increasingly being used to treat adult ADHD, both as an alternative and as a supplement to pharmacotherapy. A thorough overview of the literature on psychoeducation for adult ADHD is lacking. The objectives of this scoping review were therefore to identify the characteristics of psychoeducation interventions designed for adults with ADHD, examine how the patient experience or perspective is considered during the intervention's development and implementation, determine the typical themes covered, and explore how 'psychoeducation' is defined in these interventions., Methods: A comprehensive search was performed to identify records in MEDLINE, Embase, PsycINFO, Web of Science, Cochrane CENTRAL, AMED, and ClinicalTrials.gov. Two or more reviewers were included in every step of the screening process and the final selection of included studies. The Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist (Supplementary Material 1) was used to report the results, and the framework developed by Arksey and O'Malley was used as a guide throughout the scoping process., Results: A total of 2121 records were identified through the literature search. After screening and full-text analysis, ten studies were included for final analysis. Most studies were conducted in Europe and followed a group format. Seven main themes were identified: Information about the diagnosis, treatment options, somatic health and ADHD, the insider perspective, ADHD and social life, coping and psychological skills, and ADHD and work. There was significant overlap in themes covered, but coverage of each theme varied. Themes deemed important by newer research, such as sexuality and gender-specific issues, were missing. Only one intervention involved patients in its development and implementation, and two interventions involved family members. There was variation in how psychoeducation was defined in the included studies, and the implications of this are discussed., Conclusion: The literature on psychoeducation for adult ADHD is not ready for any systematic effect estimation. Before such estimations are conducted, a shared understanding and definition of psychoeducation are needed. The involvement of end users in the development and delivery of interventions may aid reach this goal but results from this review indicate that such practices are rare., (© 2024. The Author(s).)

- Abstract
Introduction: Patient satisfaction with mental health services has for several decades been considered an important component when evaluating service quality. It is often assessed in the context of monitoring quality of care, developing or evaluating newly implemented interventions or changes in practice. Because of this, patient satisfaction questionnaires are often added to longer questionnaire batteries, and shorter questionnaires are preferred to prevent respondent fatigue and non-compliance and to secure easy implementation. However, most studies use unvalidated patient satisfaction measures, making comparisons between studies difficult. Validation studies of short patient satisfaction measures are therefore warranted., Methods: The primary aim was to examine the construct validity and internal reliability of the Client Satisfaction Questionnaire-4 (CSQ-4) in a Norwegian outpatient mental health setting. A total of 467 patients were recruited from an outpatient psychiatric care clinic in Central Norway. The secondary aim was to examine an earlier proposed cutoff for classifying dissatisfied patients in this new population. A principal component analysis was conducted to evaluate factor structure, correlation analyses were conducted to test for predicted relationships, and Cronbach's alpha was calculated to examine internal reliability., Results: The CSQ-4 showed a clear unidimensional structure with one factor explaining 80% of its variance. Its internal reliability was very high, with a Cronbach's alpha of 0.92. As hypothesised this study found no statistically significant sex differences in satisfaction and no statistically significant association between age and satisfaction. Positive changes in symptoms during treatment and higher post-treatment functional impairment were associated with higher patient-reported treatment satisfaction scores, which indicates good construct validity., Conclusion: This is the first study to evaluate the CSQ-4 in a psychiatric population. The CSQ-4 demonstrated good structural validity and internal reliability and was correlated with outcome variables in terms of symptom change and post-treatment functioning. In sum, this indicates that the CSQ-4 is a good short alternative for evaluating patient satisfaction in routine outpatient mental health care., (© 2023. The Author(s).)

- Abstract
Objectives: The General Self-Efficacy (GSE) scale is a validated self-rated questionnaire increasingly used in mental health research. However, despite several psychometric advantages of the GSE scale, its validity in those diagnosed with attention-deficit/hyperactivity disorder (ADHD) has not yet been examined. Moreover, a shorter version of the GSE scale would contribute to a more rational use of resources in extensive multivariate studies. Therefore, as self-rated scales to measure self-efficacy in this population are lacking, the current study aims to develop a condensed version of the GSE for adults with ADHD., Methods: A group of patient collaborators (user representatives) from an ADHD organization and health professionals shortened the original 10-item GSE scale to six items and evaluated the content validity of the revised scale. Second, 525 potential participants were invited to participate in a cross-sectional study conducted in 2021 (between January 19th and February 7th). Of them, 403 filled out the GSE-6 for ADHD and two scales measuring psychological well-being and mental health (the five-item World Health Organization Well-Being Index, WHO-5, and the four-item Patient Health Questionnaire, PHQ-4). The psychometric properties of the new scale were examined, testing a priori formulated hypotheses., Results: The brief GSE-6 for ADHD displayed good internal consistency with a Cronbach's α of 0.907. No floor or ceiling effect was detected. Exploratory and confirmatory factor analyses supported a one-factor structure. The GSE-6 also showed a moderate positive correlation with the WHO-5 ( r
s = 0.578) and a moderate negative correlation with the depression and anxiety rating scale PHQ-4 ( rs = -0.595)., Conclusion: The 6-item GSE for ADHD was evaluated to have good content validity. The scale demonstrated good psychometric properties. The results indicate that the GSE-6 may help assess self-efficacy in adults with ADHD., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Skliarova, Pedersen, Hafstad, Vaag, Lara-Cabrera and Havnen.)- Published

- Abstract
Background: Persons with attention-deficit/hyperactivity disorder (ADHD) frequently experience symptoms of anxiety and depression. In this population, there is a need for validated brief self-report screening questionnaires to assess the severity of comorbid mental health problems. The Patient Health Questionnaire 4 (PHQ-4) is a self-report questionnaire that may contribute to this purpose as it can screen for both disorders efficiently. However, this will be the first study examining the factor structure of the PHQ-4 in samples of adults with ADHD, and also evaluating the validity of the Norwegian version of the PHQ-4., Objectives: The aim of the current cross-sectional study was to examine the factor structure and validity of the Norwegian version of the PHQ-4 in a sample of adults who reported having been diagnosed with ADHD., Methods: Of 496 invited, a total of 326 participants (66%) completed the PHQ-4, The World Health Organization Five Well-Being Index, the Oslo Social Support Scale and the 4-item Perceived Stress Scale electronically in a web-portal between the 9th and 30th of June 2020., Results: Confirmatory factor analysis of the PHQ-4 supported a two-factor structure [RMSEA = 0.038 (90% CI 0.000-0.159), CFI = 1.00, TLI = 0.999, SRMR = 0.004], consisting of a depression factor and an anxiety factor. Standardized factor loadings were 0.79 to 0.97. The PHQ-4 was negatively correlated with well-being and social support and positively correlated with perceived level of stress., Conclusion: This study indicates promising psychometric properties of the PHQ-4 as a measure of anxiety and depressive symptoms in adults with self-reported ADHD who are fluent in Norwegian. The questionnaire's brevity makes it a valuable resource in research and clinical settings. However, more studies are needed to test the instrument in a clinical sample., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Havnen, Lydersen, Mandahl and Lara-Cabrera.)

- Abstract
Aims: Because of the COVID-19 lockdown, an internet-based adaption of a nurse-led cognitive behavioural group therapy (CGBT) was provided for perpetrators of domestic violence. The aim of this study was to describe the development of the therapy, examine the initial feasibility and impact on patient satisfaction of the programme and evaluate the associated patient-reported experiences., Design: Programme development as well as testing its feasibility and acceptability using cross-sectional survey data., Methods: Anonymous data were collected at a university hospital in Norway between October and December 2021. Feasibility was examined by comparing the numbers of patients who agreed to participate, chose not to participate or dropped out during the intervention. There was a self-reporting scale that evaluated patient satisfaction, and the participants were invited to make suggestions for improvement of the intervention. The results of the study are reported in accordance with the STROBE checklist., Results: The videoconference-delivered CGBT was feasible. Two of the 67 patients refused to attend therapy delivered in a remote manner (3.0%), and four patients (6.0%) were classified as non-completers. Overall, patients were satisfied with the therapy., Conclusions: This study described a promising nurse-led internet-based intervention for individuals who were domestically violent and had voluntarily sought healthcare help. The participants' satisfaction with the intervention indicates its acceptability and feasibility. However, research on internet-based cognitive behaviour therapy is still in its infancy. These results may guide the future development of internet-based cognitive behavioural therapy (CBT) for individuals who perpetrate domestic violence. Further research is needed on the pros and cons of this mode of service delivery., Impact: This study addressed the challenges of providing treatment for domestic violence during the COVID-19 pandemic by examining videoconference-delivered CBT for individuals who perpetrate domestic violence., (© 2022 The Authors.

- Abstract
Background: This study aimed to explore the internal consistency and factor validity of the 13-item self-report questionnaire Parent-Patient Activation Measure (P-PAM) in a sample of parents of children with Attention-deficit/hyperactivity disorder., Methods: In a cross-sectional study, 239 parents were recruited from four outpatient clinics of the Child and Adolescent Mental Health Services and completed the P-PAM along with demographic variables. The factor structure of the P-PAM was examined through exploratory factor analysis, and internal consistency was estimated with the use of both Cronbach's alpha and McDonald's omega. A confirmatory factor analysis was used to estimate and test individual parameters., Results: The fit indices suggest an acceptable two-factor model of P-PAM and show high internal consistency and reliability for both factors, indicating that the scale measures two concepts., Conclusions: Our findings provide evidence for an acceptable factor structure and a high reliability of P-PAM as a measure of parent activation, suggesting that the theoretical factors reflect the construct of parent activation as intuitively compiled into an inner cognitive factor and an outer behavioral factor, which are related., (© 2023.

- Abstract
Background: Validated measures of patient-reported experiences are essential for assessing and improving the quality of mental health services and interventions. In Norwegian mental healthcare settings, the Client Satisfaction Questionnaire (CSQ-8) is increasingly being used for this purpose, but the validity and reliability of the Norwegian translation have not been investigated., Methods: We examined the factor structure and internal consistency of a digitally administrated Norwegian translation of the CSQ-8 in a sample of 338 patients recruited from outpatient treatment. The relationship between satisfaction scores and the change in symptom severity during treatment, measured by the Patient Health Questionnaire-4, was also investigated., Results: The Norwegian CSQ-8 showed a clear unidimensional structure with one factor explaining 74% of the variance. Internal consistency was very high, with a Cronbach's alpha of 0.95. Satisfaction showed a small-to-moderate negative relationship with change in symptom severity. Satisfaction scores were negatively skewed, and the presence of ceiling effects is discussed., Conclusion: Our results support the use of the Norwegian CSQ-8 as a valid and reliable measure of satisfaction with mental healthcare services. Further studies are needed to determine the test-retest reliability of the questionnaire, its sensitivity to change, and to assess its propensity to ceiling effects., (© 2022. The Author(s).)

- Abstract
Purpose: Research on the psychological well-being of caregivers of children diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) suggests that the well-being of parents and caregivers has been negatively affected by the COVID-19 pandemic. Although the psychological well-being of caregivers is a major concern, few validated well-being measures exist for caregivers of children diagnosed with ADHD. Therefore, a valid self-report scale is needed to assess well-being during the pandemic. The brief Five-Item World Health Organization Well-Being Index (WHO-5) has previously been used in studies on caregivers. However, its validity in this population remains unknown. This study aimed to evaluate the reliability and construct validity of the WHO-5 with caregivers of children with ADHD. Methods : A cross-sectional anonymous online survey was conducted in Norway. The study recruited caregivers from a community sample during the COVID-19 pandemic. This was carried out to investigate the construct validity by exploring the relationship between well-being, quality of life, social support, self-reported psychological distress, and perceived stress. Results : The findings of unidimensionality and high internal consistency, together with the results from the hypothesis testing, demonstrate the reliability and construct validity of the Norwegian version of the WHO-5 in this population. Conclusions: This study provides the first empirical evidence of the validity and reliability of the WHO-5 from a sample of Norwegian caregivers of children diagnosed with ADHD, with excellent reliability and construct validity. The scale can be used to systematize the measurement of well-being in caregivers because of its brevity and good psychometric properties, making it a valuable resource in research settings and assisting healthcare professionals in their crucial work of caring for caregivers.

- Abstract
Nurses' well-being has been increasingly recognised due to the ongoing pandemic. However, no validation scales measuring nurses' well-being currently exist. Thus, we aimed to validate the WHO-5 Well-Being Index (WHO-5) in a sample of nurses. A cross-sectional multinational study was conducted, and a total of 678 nurses who worked during the COVID-19 pandemic in Spain (36.9%), Chile (40.0%) and Norway (23.1%) participated in this study. The nurses completed the WHO-5, the Patient Health Questionnaire-2 (PHQ-2), the Generalized Anxiety Disorder-2 (GAD-2) and three questions about the quality of life (QoL). The WHO-5 demonstrated good reliability and validity in the three countries. Cronbach's alphas ranged from 0.81 to 0.90. High correlations were found between the WHO-5 and the psychological well-being dimension of QoL, and negative correlations between the WHO-5 and PHQ-2. The unidimensional scale structure was confirmed in all the countries, explaining more than 68% of the variance. The item response theory likelihood ratio model did not show discernible differences in the WHO-5 across the countries. To conclude, the WHO-5 is a psychometrically sound scale for measuring nurses' well-being during a pandemic. The scale showed strong construct validity for cross-cultural comparisons; however, more research is required with larger sample sizes.

- Abstract
Background: The coronavirus disease 2019 pandemic is impacting the delivery of healthcare worldwide, creating dilemmas related to the duty to care. Although understanding the ethical dilemmas about the duty to care among nurses is necessary to allow effective preparation, few studies have explored these concerns., Aim: This study aimed to identify the ethical dilemmas among clinical nurses in Spain and Chile. It primarily aimed to (1) identify nurses' agreement with the duty to care despite high risks for themselves and/or their families, (2) describe nurses' well-being and (3) describe the associations between well-being and the duty to care., Research Design: Cross-sectional self-reported anonymous data were collected between May and June 2020 via electronic survey distribution (snowball sampling)., Ethical Considerations: The Institutional Ethical Review Committees in both countries approved the study (CHUC_2020_33 and 27/2020)., Findings: In total, 345 clinical nurses answered the primary question about the duty to care for the sick. Although in the total sample 77.4% agreed they have a duty to care for the sick, significant differences were found between the Spanish and Chilean samples. Overall, 53.6% of the nurses reported low levels of well-being; however, among those reporting low well-being, statistically significant differences were found between Spanish and Chilean nurses as 19.4% and 37.8%, respectively, disagreed with the statement regarding the duty to care., Discussion: Participants in both countries reported several ethical dilemmas, safety fears, consequent stress and low well-being. These results suggest that prompt actions are required to address nurses' ethical concerns, as they might affect their willingness to work and psychological well-being., Conclusion: Our findings shed light on the ethical dilemmas nurses are facing related to the duty to care. Not only has the coronavirus disease 2019 pandemic given rise to ethical challenges, but it has also affected nurses' well-being and willingness to work during a pandemic.

- Abstract
Introduction: The current COVID-19 pandemic interferes with family lives across the world, particularly families of children with neurodevelopmental disorders (NDDs) are at a greater risk for being negatively impacted by the pandemic. Together with representatives from this caregiver population the aim was to explore the interference associated with normal family life caused by the COVID-19 pandemic., Method: This is a descriptive study using a cross-sectional design. Following a strategic network sampling strategy, a user-developed national survey was completed by a larger sample (N = 1,186) of parents and informal caregivers of children with NDDs. The survey utilized a combination of both closed and open-ended questions, and a logistic regression analysis was carried out to assess the association between family characteristics, characteristics of the child, and COVID-19 related family life interference. Before carrying out the regression an inductive content analysis of the open-ended question on `How has the isolation affected the family´ was carried out to construct the outcome variable., Results: The initial analysis indicated that the COVID-19 pandemic induced a shift in everyday family life and a lack of guidance and support related to managing the challenges they were facing. Caregivers who reported that COVID-19 had significantly interfered with their family life, were more likely to report having anxious children, and to have experienced an increased number of conflicts at home. The logistic regression showed that both anxious children and increased conflicts considerably increased the risk for reporting family life interference compared to those that reported no increased conflicts or anxious children., Discussion: Considering how the COVID-19 related increased conflicts at home and anxious children threaten the family life of the NDD caregiver population, as an external source of family stress, which might lead to negative impact on their mental and physical well-being, the need for further research in collaboration with user representatives is apparent. Our study suggests that more information should be provided to healthcare providers, social professionals, peers, people with NDDs, and caregivers of people with NDDs about the potential threats that a stressful life event such as the current pandemic can pose to their mental and physical health and their family life., (© 2022.

- Abstract
The COVID-19 pandemic has created great uncertainty around the world, and due to the pandemic, nurses have been exposed to an increase in highly stressful clinical situations. This study examines the relationships between perceived stress and emotional disorders among nurses who have provided direct patient care during the COVID-19 pandemic and explores the mediating role of resilience in these relationships. In an online cross-sectional design, we asked Spanish nurses ( N = 214) to complete self-reported scales, and we performed correlation and mediation analyses between perceived stress (Perceived Stress Scale, PSS-4), resilience (Wagnild Resilience Scale, RS-14), wellbeing (World Health Organization Wellbeing Index, five items, WHO-5), anxiety (PHQ-2) and depression (GAD-2). The nurses self-reported moderate levels of perceived stress, considerable psychological distress and high resilience. We found resilience to be significantly negatively correlated with the reported levels of perceived stress, anxiety and depression ( p < 0.001). The mediating analysis revealed that resilience played a protective role in the direct relationships of stress with depression, anxiety, and psychological distress. To conclude, our findings supported the hypothesis that resilience mediated the relationship between stress and mental health.

- Abstract
After the European colonization of the Americas, there was a dramatic population collapse of the Indigenous inhabitants caused in part by the introduction of new pathogens. Although there is much speculation on the etiology of the Colonial epidemics, direct evidence for the presence of specific viruses during the Colonial era is lacking. To uncover the diversity of viral pathogens during this period, we designed an enrichment assay targeting ancient DNA (aDNA) from viruses of clinical importance and applied it to DNA extracts from individuals found in a Colonial hospital and a Colonial chapel (16th-18th century) where records suggest that victims of epidemics were buried during important outbreaks in Mexico City. This allowed us to reconstruct three ancient human parvovirus B19 genomes and one ancient human hepatitis B virus genome from distinct individuals. The viral genomes are similar to African strains, consistent with the inferred morphological and genetic African ancestry of the hosts as well as with the isotopic analysis of the human remains, suggesting an origin on the African continent. This study provides direct molecular evidence of ancient viruses being transported to the Americas during the transatlantic slave trade and their subsequent introduction to New Spain. Altogether, our observations enrich the discussion about the etiology of infectious diseases during the Colonial period in Mexico., Competing Interests: AG, VV, MS, JW, JG, MM, AM, GS, PS, BT, DB, MÁ None, MB none, (© 2021, Guzmán-Solís et al.)

- Abstract
Ammonia (NH
3 ) volatilization from broiler (Gallus gallus domesticus) litter is a microbially mediated process that can decrease bird productivity and serves as an environmental pollutant. The release of NH3 is strongly influenced by the pH of litter. Flue-gas desulfurization gypsum (FGDG) has been suggested as a potential amendment to reduce NH3 volatilization due to the pH buffering capacity of calcium carbonate (CaCO3 ) precipitation. However, its effect on litter pH is not as pronounced as acidifying agents, such as aluminum sulfate (alum). The main objective of our study was to develop an acidified-FGDG amendment that has a more pronounced effect on litter pH and NH3 volatilization than FGDG alone. We conducted a 33-d incubation in which litter pH, NH3 volatilization, nitrogen mineralization, PLUP-ureC gene abundance, and CaCO3 precipitation were measured. Treatments in the study included: broiler litter (BL), broiler litter + 20% FGDG (BL+FGDG), broiler litter + FGDG-alum mixture (BL+FGDG+A6), broiler litter + 6% alum (BL+A6), and broiler litter + 10% alum (BL+A10). Our FGDG+alum amendment decreased litter pH (0.68 pH units) and PLUP-ureC gene abundance (>1 log) compared with FGDG alone and the control (p < .05). This led to a 25% decrease in cumulative NH3 loss after 33 d. The addition of FGDG alone did not have an effect on litter pH (p = .36) or cumulative NH3 loss (p = .29) due to a lack of significant CaCO3 precipitation. Treating litter with 6 and 10% alum was the most effective amendment for reducing pH and cumulative NH3 loss., (© 2021 The Authors.

- Abstract
Host genetic landscapes can shape microbiome assembly in the animal gut by contributing to the establishment of distinct physiological environments. However, the genetic determinants contributing to the stability and variation of these microbiome types remain largely undefined. Here, we use the free-living nematode Caenorhabditis elegans to identify natural genetic variation among wild strains of C. elegans that drives assembly of distinct microbiomes. To achieve this, we first established a diverse model microbiome that represents the strain-level phylogenetic diversity naturally encountered by C. elegans in the wild. Using this community, we show that C. elegans utilizes immune, xenobiotic, and metabolic signaling pathways to favor the assembly of different microbiome types. Variations in these pathways were associated with enrichment for specific commensals, including the Alphaproteobacteria Ochrobactrum. Using RNAi and mutant strains, we showed that host selection for Ochrobactrum is mediated specifically by host insulin signaling pathways. Ochrobactrum recruitment is blunted in the absence of DAF-2/IGFR and modulated by the competitive action of insulin signaling transcription factors DAF-16/FOXO and PQM-1/SALL2. Further, the ability of C. elegans to enrich for Ochrobactrum as adults is correlated with faster animal growth rates and larger body size at the end of development. These results highlight a new role for the highly conserved insulin signaling pathways in the regulation of gut microbiome composition in C. elegans., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2021 The Author(s).

- Abstract
Background: Shared decision-making (SDM), a collaborative approach that includes and respects patients' preferences for involvement in decision-making about their treatment, is increasingly advocated. However, in the practice of clinical psychiatry, implementing SDM seems difficult to accomplish. Although the number of studies related to psychiatric patients' preferences for involvement is increasing, studies have largely focused on understanding patients in public mental healthcare settings. Thus, investigating patient preferences for involvement in both public and private settings is of particular importance in psychiatric research. The objectives of this study were to identify different latent class typologies of patient preferences for involvement in the decision-making process, and to investigate how patient characteristics predict these typologies in mental healthcare settings., Methods: We conducted latent class analysis (LCA) to identify groups of psychiatric outpatients with similar preferences for involvement in decision-making to estimate the probability that each patient belonged to a certain class based on sociodemographic, clinical and health belief variables., Results: The LCA included 224 consecutive psychiatric outpatients' preferences for involvement in treatment decisions in public and private psychiatric settings. The LCA identified three distinct preference typologies, two collaborative and one passive, accounting for 78% of the variance. Class 1 (26%) included collaborative men aged 34-44 years with an average level of education who were treated by public services for a depressive disorder, had high psychological reactance, believed they controlled their disease and had a pharmacophobic attitude. Class 2 (29%) included collaborative women younger than 33 years with an average level of education, who were treated by public services for an anxiety disorder, had low psychological reactance or health control belief and had an unconcerned attitude toward medication. Class 3 (45%) included passive women older than 55 years with lower education levels who had a depressive disorder, had low psychological reactance, attributed the control of their disease to their psychiatrists and had a pharmacophilic attitude., Conclusions: Our findings highlight how psychiatric patients vary in pattern of preferences for treatment involvement regarding demographic variables and health status, providing insight into understanding the pattern of preferences and comprising a significant advance in mental healthcare research.

- Abstract
Background: The brief generic Multicultural Quality of Life Index (MQLI) is a culturally informed self-report 10-item questionnaire used to measure health-related quality of life (QoL). QoL is an important outcome measure in guiding healthcare and is held as a substantial parameter to evaluate the effectiveness of healthcare. Attention Deficit Hyperactivity Disorder (ADHD) in children might negatively influence the parents' QoL. Having a validated questionnaire to measure QoL for this population will therefore be a vital first step in guiding healthcare for parents of children with ADHD. We aimed to examine the reliability and validity of the Norwegian version of the MQLI in a sample of parents of children with ADHD. Methods: In a cross-sectional study, 128 parents of children with ADHD were recruited from four outpatient clinics within the Child and Adolescents Mental Health Services (CAMHS) in Norway. They completed the MQLI along with an alternative well-being scale, the Five-item World Health Organization Well-being Index (WHO-5), and a form including demographic variables. Reliability and validity of the MQLI were examined. We conducted a factor analysis and calculated internal consistency and the correlation between the MQLI and the WHO-5. Results: Factor analysis of the parents reported MQLI yielded a one-factor solution. For the MQLI, Cronbach's alpha was 0.73. The correlation between the two measures of MQLI and WHO-5 was high ( r = 0.84), reflecting convergent validity since the association between the two measures was strong. Conclusion: Results from this study support the reliability and validity of the Norwegian version of the MQLI for assessment of quality of life in parents of children with ADHD with good psychometric properties. Study findings support the use of the questionnaire in CAMHS., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Mundal, Laake, Mezzich, Bjørkly and Lara-Cabrera.)

- Abstract
Patient Activation Measure-13 (PAM-13) is a valid and widely used questionnaire that assess an individual's knowledge, confidence, and skills for self-management of their chronic illness. Although there is some evidence regarding its reliability, the test-retest reliability has not been investigated among patients with substance use disorders (SUDs) or schizophrenia spectrum disorders. We investigated the internal consistency and test-retest reliability of PAM-13 in these populations. Test-retest reliability was analysed using data from 29 patients with SUDs and 28 with schizophrenia spectrum disorders. Cronbach's α and Intraclass Correlation Coefficient (ICC) scores were used to examine internal consistency and test-retest reliability, respectively. Of the 60 collected test-retest questionnaires, 57 were included in the analyses. No mean differences between time one (T1) and time two (T2) were observed in either patient group, except for item 12 in schizophrenia spectrum disorders patients ( p < 0.05). Internal consistency for T1 and T2 was 0.75 and 0.84 in SUDs patients and 0.87 and 0.81 in schizophrenia spectrum disorders patients, respectively. The ICC was r = 0.86 in patients with SUDs and r = 0.93 in patients with schizophrenia spectrum disorders. To conclude, PAM-13 showed good internal consistency and test-retest reliability in SUDs and schizophrenia spectrum disorders patients.

- Abstract
Introduction: Significant numbers of children with attention deficit hyperactivity disorder (ADHD) display problems that cause multiple disabilities, deficits and handicaps that interfere with social relationships, development and school achievement. They may have multiple problems, which strain family dynamics and influence the child's treatment. Parent activation, described as parents' knowledge, skills and confidence in dealing with their child's health and healthcare, has been shown to be an important factor in improving health outcomes. Research suggests that parents need edification to learn skills crucial to the treatment and management of their children's healthcare. Promoting positive parenting techniques may reduce negative parenting factors in families. This study aims to assess the acceptability, feasibility and estimated sample size of a randomised controlled trial (RCT) comparing an ADHD peer co-led educational programme added to treatment as usual (TAU)., Methods and Analysis: Using a randomised waitlist controlled trial, parents of children aged 6-12 years newly diagnosed with ADHD, and referred to a child mental health outpatient clinic in Mid-Norway, will receive TAU concomitant with a peer co-facilitated parental engagement educational programme (n=25). Parents in the control group will receive TAU, and the educational programme treatment within a waitlist period of 3-6 months (n=25). Parent activation, satisfaction, well-being, quality of life and treatment adherence, will be assessed at baseline (T0), 2 weeks (T1) pre-post intervention (T2, T3) and at 3 months follow-up (T4). Shared decision making, parents preferred role in health-related decisions and involvement, parent-reported symptoms of ADHD and child's overall level of functioning will be assessed at T0 and T4. Such data will be used to calculate the required sample size for a full-scale RCT., Ethics and Dissemination: Approval was obtained from the Regional Committee for Medicine and Health Research Ethics in Mid-Norway (ref: 2018/1196). The findings of this study are expected to provide valuable knowledge about how to optimise family education and management of ADHD and will be disseminated through presentations at conferences and publication in peer-reviewed journals., Trial Registration Number: NCT04010851., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

- Abstract
The 'red complex' is an aggregate of three oral bacteria ( Tannerella forsythia , Porphyromonas gingivalis and Treponema denticola ) responsible for severe clinical manifestation of periodontal disease. Here, we report the first direct evidence of ancient T. forsythia DNA in dentin and dental calculus samples from archaeological skeletal remains that span from the Pre-Hispanic to the Colonial period in Mexico. We recovered twelve partial ancient T. forsythia genomes and observed a distinct phylogenetic placement of samples, suggesting that the strains present in Pre-Hispanic individuals likely arrived with the first human migrations to the Americas and that new strains were introduced with the arrival of European and African populations in the sixteenth century. We also identified instances of the differential presence of genes between periods in the T. forsythia ancient genomes, with certain genes present in Pre-Hispanic individuals and absent in Colonial individuals, and vice versa . This study highlights the potential for studying ancient T. forsythia genomes to unveil past social interactions through analysis of disease transmission. Our results illustrate the long-standing relationship between this oral pathogen and its human host, while also unveiling key evidence to understand its evolutionary history in Pre-Hispanic and Colonial Mexico.

- Abstract
Background/objective: CollaboRATE is a 3-item self-report measure of the patient experience of shared decision-making (SDM) process. The objective of this study is to assess the psychometric properties of CollaboRATE in community mental health care., Method: A cross-sectional study was conducted at a Community Mental Health Center of the Canary Islands Health Service. Two hundred and fifty consecutive psychiatric outpatients were invited to participate. Of those, 191 accepted (76.40% of response rate) and completed the CollaboRATE, the Control Preferences Scale (CPS), and a form with sociodemographic and clinical variables., Results: Exploratory factor analysis ratified the unidimensionality of the measure. High internal consistency was found (α Cronbach = .95, Guttman's λ = .93, and ω = .95). Strong positive correlations ( p < .0001) were found between the CollaboRATE and the CPS. Only 39.80% of respondents gave the best possible score on CollaboRATE., Conclusions: This study provides evidence for the reliability and validity of the Spanish version of the CollaboRATE as a measure of SDM. The measure is quick to complete and feasible for use in outpatient mental health care. At present, a significative number of psychiatric outpatients are not involved in SDM. The use of this measure in psychiatric routine care can be a key tool in assessing and implementing SDM., (© 2020 Asociación Española de Psicología Conductual. Published by Elsevier España, S.L.U.)

- Abstract
The Five-item World Health Organization Well-being Index (WHO-5) is an increasingly used measure of generic well-being, but there is no evidence to support whether outpatients consider the questionnaire valuable. As the WHO-5 has not yet been psychometrically evaluated in specialised community mental health settings, an evaluation of its validity seems warranted. The aim of this cross-sectional study was to examine the psychometric properties of the WHO-5 in this type of setting. Data was collected from an outpatient center (N = 191 adults). Results indicate that the questionnaire was feasible to administer (n = 57 patients), it reported low mean Burden-scores and high Positive-Value scores, and had excellent internal consistency. No evidence of floor or ceiling effects was found. Results supported the unidimensional structure of the questionnaire. Significant differences were found concerning patients' diagnoses, with patients with schizophrenia diagnoses reporting higher scores and patients with depression and personality disorders reporting lower ones. When comparing the WHO-5 total score and patients' attitudes toward medication, negative correlations were observed with psychological reactance, as well as positive aspects of psychiatric medication. The present study demonstrates that the WHO-5 is feasible to administer and has robust psychometric properties in specialised community mental health centres., Competing Interests: Declaration of Competing Interest No conflict of interest has been declared by the authors., (Copyright © 2020 Elsevier B.V.

- Abstract
Background: Violence in close relationships is a global public health problem and there is a need to implement therapeutic programs designed to help individuals who voluntarily seek help to reduce recurrent intimate partner violence. The effectiveness of such interventions in this population remains inconclusive. The aim of the present study was to compare the effectiveness of cognitive-behavioural group therapy (CBGT) vs mindfulness-based stress reduction (MBSR) group therapy in reducing violent behavior amongst individuals who are violent in intimate partnerships and who voluntarily seek help., Methods: One hundred forty four participants were randomized using an internet-based computer system. Nineteen withdrew after randomization and 125 participants were randomly assigned to the intervention condition (CBGT, n = 67) or the comparator condition (MBSR, n = 58). The intervention condition involved two individual sessions followed by 15 cognitive-behavioural group therapy sessions. The comparator condition included one individual session before and after 8 mindfulness-based group sessions. Participants (N = 125) and their relationship partners (n = 56) completed assessments at baseline, and at three, six, nine and twelve months' follow-up. The pre-defined primary outcome was reported physical, psychological or sexual violence and physical injury as measured by the revised Conflict Tactics Scale (CTS2)., Results: The intent-to-treat analyses were based on 125 male participants (intervention group n = 67; comparator group n = 58). Fifty-six female partners provided collateral information. Baseline risk estimate in the CBGT-group was .85 (.74-.92), and .88 (.76-.94) in the MBSR-group for physical violence. At 12-months' follow-up a substantial reduction was found in both groups (CBGT: .08 (.03-.18); MBSR: .19 (.11-.32))., Conclusion: Results provide support for the efficacy of both the cognitive-behavioural group therapy and the mindfulness-based stress reduction group therapy in reducing intimate partner violent behavior in men voluntarily seeking treatment., Trial Registration: NCT01653860, registered July 2012.

- Abstract
Little is known about the mechanisms through which routine outcome monitoring (ROM) influences psychotherapy outcomes. In this secondary analysis of data from a randomized clinical trial (Brattland et al., 2018), we investigated whether the working alliance mediated the effect of the Partners for Change Outcome Monitoring System (PCOMS), a ROM system that provides session-by-session feedback on clients' well-being and the alliance. Adult individuals (N = 170) referred for hospital-based outpatient mental health treatment were randomized to individual psychotherapy either with the PCOMS ROM system, or without (treatment as usual [TAU]). Treatment was provided by the same therapists (N = 20) in both conditions. A multilevel mediation model was developed to test if there was a significant indirect effect of ROM on client impairment at posttreatment through the alliance at 2 months' treatment controlled for first-session alliance. Alliance ratings increased more from session 1 to 2 months' treatment in the ROM than TAU condition, and alliance increase was associated with less posttreatment impairment. A significant indirect effect of ROM on treatment outcomes through alliance increase (p = .043) explained an estimated 23.0% of the effect of ROM on outcomes. The results were consistent with a theory of the alliance as one mechanism through which ROM works. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

- Abstract
Computer models are commonly used for predicting risks of runoff P loss from agricultural fields by enabling simulation of various management practices and climatic scenarios. For P loss models to be useful tools, however, they must accurately predict P loss for a wide range of climatic, physiographic, and land management conditions. A complicating factor in developing and evaluating P loss models is the relative scarcity of available measured field data that adequately capture P losses before and after implementing management practices in a variety of physiographic settings. Here, we describe the development of the P Loss in runoff Events from Agricultural fields Database (PLEAD)-a compilation of event-based, field-scale dissolved and/or total P loss runoff loadings from agricultural fields collected at various research sites located in the US Heartland and southern United States. The database also includes runoff and erosion rates; soil-test P; tillage practices; planting and harvesting rates and practices; fertilizer application rate, method, and timing; manure application rate, method, and timing; and livestock grazing density and timing. In total, >1800 individual runoff events-ranging in duration from 0.4 to 97 h-have been included in the database. Event runoff P losses ranged from <0.05 to 1.3 and 3.0 kg P ha for dissolved and total P, respectively. The data contained in this database have been used in multiple research studies to address important modeling questions relevant to P management planning. We provide these data to encourage additional studies by other researchers. The PLEAD database is available at ., (Copyright © by the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc.)

- Abstract
Background: Psychoeducation is included in the Norwegian national guidelines for treatment of adult ADHD. Despite some promising results for the treatment of other conditions and ADHD, little is known about the efficacy of such interventions. This paper presents a protocol for a pilot randomized controlled trial featuring a psychoeducational group program for patients with ADHD. The main objective of this pilot trial is to investigate adherence, feasibility, and preliminary efficacy of a ten-session psychoeducational group designed to address specific challenges faced by adults diagnosed with ADHD., Methods: This pilot study will evaluate patient satisfaction and preliminary efficacy of a psychoeducational group treatment using a randomized waitlist-controlled trial at two different outpatient clinics in mid-Norway. All participants will receive treatment as usual, concomitant with the intervention and waitlist period. Client satisfaction (CSQ 8), general self-efficacy (GSE-6), ADHD-related quality of life (AAQoL), symptoms of ADHD (SCL-9; ASRS), and work participation will be assessed at the time of recruitment prior to randomization (T0), pre-intervention (T1), post-intervention (T2), and at 10 weeks follow-up (T3). Recruitment and dropout rates along with treatment adherence will also be evaluated., Discussion: This study offers valuable insight into the preliminary efficacy of educational programs implemented in outpatient clinics. The aim of the trial is to evaluate adherence, feasibility, patient satisfaction, and the preliminary efficacy of a psychoeducational group intervention for patients with adult ADHD and provide further insight into the design and construction of a large-scale trial. The results also offer preliminary empirical evidence to inform the development of larger and more complex studies., Trial Registration: NCT03337425, Registered 9 November 2017., Competing Interests: All participants sign a written informed consent to participate.

- Abstract
Background: Violence against intimate partners is a worldwide public health problem. Cognitive behavioural therapy delivered in a group format is widely used for the treatment of men's violent behaviour towards their female partners. A Cochrane review about the effectiveness of this therapy from 2011 revealed a lack of controlled studies. Our aim is to update the current evidence on the effectiveness of cognitive behavioural group therapy on men's violent behaviour towards their female partner., Methods: The Cochrane Library, the Campbell Collaboration Social, MEDLINE, PsychINFO, CINAHL, SCOPUS, Embase, Open Grey, Grey Literature Report, and Sociological Abstracts were searched for studies investigating the effectiveness of cognitive behavioural group therapy on intimate partner violence published in the period of January 1, 2010, to February 12, 2018. Manual searches were also performed to identify randomized and non-randomized controlled trials. Data extraction was done in duplicate. The primary outcome was the reduction in violent behaviour, and secondary outcomes were physical health, mental health, quality of life, emotion regulation, and substance use. Study quality was assessed with the Cochrane Collaboration's risk of bias tool and the Risk of Bias In Non-Randomized Studies of Interventions tool. A narrative summary was used to describe the review findings., Results: We identified six new studies that met the inclusion criteria: four randomized controlled trials and two non-randomized trials. Three of the randomized controlled trials found a reduction in intimate partner violence after treatment. The fourth randomized trial found that a subsample of responding partners reported a reduction in violence but no changes in the men's self-reported violence after treatment. No effect could be detected in the two non-randomized studies. Analysis of risk of bias revealed mixed results, indicating both strengths and weaknesses., Limitations: Only a limited amount of studies which scored as "low quality" were available., Conclusions: There is still insufficient evidence to confirm that cognitive behavioural group therapy for perpetrators of intimate partner violence has a positive effect. Future research should focus on randomized controlled studies distinguishing between convicted and non-convicted populations where violent behaviour is the primary outcome., Trial Registration: CRD42016041493 .

- Abstract
Background: Epithelial-to-mesenchymal transition (EMT) of human peritoneal mesothelial cells (HPMCs) contributes to fibrotic thickening of the peritoneum that develops in patients on peritoneal dialysis (PD). The process is thought to be largely mediated by transforming growth factor-beta (TGF-β). As TGF-β has also been implicated in senescence of HPMCs, we have performed an exploratory study to examine if senescent HPMCs can undergo EMT., Methods: Omentum-derived HPMCs were rendered senescent by repeated passages in culture. Features of EMT were assessed by immunostaining and quantitative polymerase chain reaction (qPCR) at various stages of the HPMC lifespan and after treatment with or without TGF-β. The motility of HPMCs was assessed in a scratch wound migration assay., Results: Replicative senescence of HPMCs was associated with a gradual increase in the constitutive expression of EMT markers, including increased production of extracellular matrix proteins. However, senescent HPMCs also retained epithelial cell features such as cytokeratin, calretinin, and E-cadherin and showed decreased, rather than increased, motility. In contrast, exposure to TGF-β resulted in an up-regulation of mesenchymal markers and down-regulation of epithelial markers. Such effects of TGF-β occurred both in young and senescent cells, although they were less pronounced in senescence., Conclusions: Senescence of HPMCs is associated with spontaneous development of several EMT features. At the same time, senescent HPMCs preserve epithelial cell-like characteristics and are less prone to develop a full EMT phenotype in response to TGF-β. These observations may support the concept of cellular senescence being antagonistically pleiotropic with regard to EMT., (Copyright © 2019 International Society for Peritoneal Dialysis.)

- Abstract
Uneven spatial distribution of soil N in conventionally managed pastures is a function of various biotic and abiotic factors and results in poor land use efficiency. In this study, we measured soil inorganic N (at depths of 0-5, 5-10, and 10-20 cm) in a 50-m grid and specific areas of interest from eight conventionally managed beef pastures (∼17 ha each), four near Eatonton and four near Watkinsville in the southern Piedmont of Georgia, USA, to assess the effects of management, landscape, and cattle locus in spatial distribution of soil inorganic N. Significant spatial autocorrelation was observed in the soil inorganic N indicating that the regions of high inorganic N deposition were near (within 91 m of) one or more pasture equipage (hay, shade, and water). In the Watkinsville pastures, inorganic N was 65% higher within 5 m of shade than the rest of the pastures, down to a 10-cm soil depth. In the Eatonton pastures, inorganic N (0-5 cm) was 22% higher within 30 m of a hay-feeding areas than the rest of the pasture. Cattle locus calculated as cattle density (cow ha yr) was a function of pasture equipage and had a significant positive relationship with soil inorganic N. Landscape parameters (slope and elevation) significantly affected inorganic N distribution; however, the effect was small and was masked by management factors. Our results suggest that strategic placement of pasture equipage (hay, shade, and water) can effectively distribute N where needed in beef pastures, thereby increasing land use efficiency., (Copyright © by the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc.)

- Abstract
This study investigated the effects of the Partners for Change Outcome Management System (PCOMS) in adult outpatient treatment at a hospital-based mental health clinic. It also investigated whether the effects differed with the timing of the treatment within a 4-year implementation period, with clients' initial distress levels, and between therapists. Adult clients (N = 170) were randomized to treatment as usual (TAU) or routine outcome monitoring (ROM). Twenty therapists provided therapy in both conditions. Therapy outcome was measured by the Behavior and Symptoms Identification Scale (BASIS-32). Data were analyzed in a series of multilevel models (MLMs). Clients in the ROM condition were 2.5 times more likely to demonstrate improvement than those in the TAU condition. Controlling for therapist variability, the overall effect size (ES) in favor of ROM was small (d = 0.26, p = .037). The superiority for ROM over TAU increased significantly over the duration of the study. ROM effects were not moderated by clients' initial distress levels. Differences between therapists accounted for 9%-10% of the variability in outcomes, and there were no significant differences in ROM effects between therapists. ROM was associated with better treatment outcomes independent of clients' initial distress levels. Clients treated later in the study benefitted more from ROM than those treated earlier.

- Abstract
Background: Patients dropping out of mental health treatment is considered a widespread and significant obstacle to providing effective treatment, thus reducing the probability of patients achieving the desired improvement. Here, relative to ordinary treatment, we investigate the effects of providing an educational group programme before mental health treatment on mental health symptomatology and the risk of patients dropping out or prematurely discontinuing treatment., Methods: A randomized controlled trial in which adults referred to a community mental health center were randomized to either a Control Group (n = 46) or a pretreatment educational programme followed by treatment as usual (Intervention Group, n = 45). The primary outcome was self-reported mental health symptomatology assessed with BASIS-32. Data were analyzed by multilevel linear regression and Cox's regression., Results: We recruited 93 patients during a 26-month period. Assessments were performed before (0 month, baseline) and after the intervention (1 month, before treatment initiation), and after 4 and 12 months. The net difference in BASIS-32 score between 0 and 1-month was - 0.27 (95% confidence interval CI] -0.45 to - 0.09) in favor of the intervention group. Although both groups had a significant and continuous decline in psychopathology during the treatment (from 1 month and throughout the 4- and 12-month follow-up assessments), the group difference detected before treatment (between 0 and 1 month) persisted throughout the study. Premature treatment discontinuation was partially prevented. The dropout risk was 74% lower in the Intervention Group than in the Control Group (hazard ratio 0.26, 95% CI = 0.07-0.93)., Conclusions: A brief educational intervention provided before mental health treatment seems to have an immediate and long-lasting effect on psychopathology, supplementary to traditional treatment. Such an intervention might also have a promising effect on reducing treatment dropout., Trial Registration: NCT00967265 , clinicaltrials.gov . Registered August 27, 2009, retrospectively registered.

- Abstract
Broiler () litter is subject to ammonia (NH) volatilization losses. Previous work has shown that the addition of gypsum to broiler litter can increase nitrogen mineralization and decrease NH losses due to a decrease in pH, but the mechanisms responsible for these effects are not well understood. Therefore, three laboratory studies were conducted to evaluate the effect of gypsum addition to broiler litter on (i) urease activity at three water contents, (ii) calcium carbonate precipitation, and (iii) pH. The addition of gypsum to broiler litter increased ammonium concentrations ( < 0.0033) and decreased litter pH by 0.43 to 0.49 pH units after 5 d ( < 0.0001); however, the rate of urea hydrolysis in treated litter only increased on Day 0 for broiler litter with low (0.29 g HO g) and high (0.69 g HO g) water contents, and on Day 3 for litter with medium (0.40 g HO g) water content ( < 0.05). Amending broiler litter with gypsum also caused an immediate decrease in litter pH (0.22 pH units) due to the precipitation of calcium carbonate (CaCO) from gypsum-derived calcium and litter bicarbonate. Furthermore, as urea was hydrolyzed, more urea-derived carbon precipitated as CaCO in gypsum-treated litter than in untreated litter ( < 0.001). These results indicate that amending broiler litter with gypsum favors the precipitation of CaCO, which buffers against increases in litter pH that are known to facilitate NH volatilization., (Copyright © by the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc.)

- Abstract
Broiler litter contains 17β-estradiol, estrone, and testosterone, which can contaminate surface waters when surface applied to grasslands and no-till fields. The objective of this study was to evaluate the effects of litter type (full or cake cleanout), litter treatment (none or sodium bisulfate), and number of flocks raised on the litter (1-5) on sex hormone concentrations. Our results showed that in untreated broiler litter, cake cleanout had greater concentrations of 17β-estradiol, estrone, and testosterone than full cleanout, whereas in litter treated with sodium bisulfate, only the concentration of 17β-estradiol was greater in cake than in full cleanout. The concentrations of 17β-estradiol and estrone in untreated broiler litter increased as the number of flocks increased from one to three, with the largest increase observed for estrone in cake cleanout. We also sampled three broiler houses in brooding and nonbrooding sections during the growout period. We found no differences in hormone concentrations between sections of each house, but changes in hormone concentrations during growout varied depending on broiler litter water content. Water contents corresponding to ∼60% water-filled porosity favored a decrease in hormone concentrations with time, whereas a water-filled porosity of 44% was associated with increases in hormone concentration, probably due to slow decomposition rates. Our results suggest that cake cleanout of untreated litter, as well as all cleanouts from houses that have raised several flocks on the same bedding, may be good targets for treatments that can reduce hormone concentrations before the litter is surface applied to fields., (Copyright © by the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc.)

- Abstract
A major concern of the broiler industry is the volatilization of ammonia (NH3) from the mixture of bedding material and broiler excretion that covers the floor of broiler houses. Gypsum has been proposed as a litter amendment to reduce NH3 volatilization, but reports of NH3 abatement vary among studies and the mechanism responsible for decreasing NH3 volatilization is not well understood. The goal of this study was to evaluate the effect of adding 20 or 40% flue-gas desulfurization gypsum (FGDG) to broiler litter on pH, electrical conductivity (EC), water potential, urea-degrading bacteria abundance, NH3 and carbon dioxide (CO2) evolution, and nitrogen (N) mineralization in several 21-d experiments. The addition of FGDG to broiler litter increased EC by 24 to 33% (P < 0.0001), decreased urea-degrading bacteria by 48 to 57% (P = 0.0001) and increased N mineralization by 10 to 11% (P = 0.0001) as compared to litters not amended with FGDG. Furthermore, the addition of FGDG to broiler litter decreased NH3 volatilization by 18 to 28% (P < 0.0001), potentially resulting from the significantly lower litter pH values compared to un-amended litter (P < 0.0001). Findings of this study indicate that amending broiler litter with 20% FGDG can decrease NH3 volatilization and increase the fertlizer value of broiler litter., (© 2017 Poultry Science Association Inc.)

- Abstract
Objective: To investigate the effect of having a contract for self-referral to inpatient treatment (SRIT) in patients with severe mental disorders., Methods: A randomized controlled trial with 53 adult patients; 26 participants received a SRIT contract, which they could use to refer themselves into a Community Mental Health Centre up to five days for each referral without contacting a doctor in advance. Outcomes were assessed after 12 months with the self-report questionnaires Patient Activation Measure (PAM-13), Recovery Assessment Scale (RAS), and the Behavior and Symptom Identification Scale (BASIS-32) and analyzed using linear mixed and regression models., Results: There was no significant effect on PAM-13 (estimated mean difference (emd) -0.41, 95% CI (CI):-7.49-6.67), nor on the RAS (emd 0.02, CI:-0.27-0.31) or BASIS-32 (0.09, CI:-0.28-0.45). An exploratory post hoc analysis showed effect of SRIT in those with low PAM below ≤47 (p=0.049)., Conclusion: There were no group differences after 12 months, but both groups maintained their baseline levels., Practice Implications: SRIT contracts can be recommended as it supports the rights to self-determination, promote user participation in decision-making in own treatment without any indication of adverse effects., (Copyright © 2017 The Author(s).

- Abstract
Background: Biofortified maize is not only a good vehicle for provitamin A carotenoids for vitamin A deficient populations in developing countries but also a source of vitamin E, tocochromanols and phenolic compounds, which have antioxidant properties. Using high-performance liquid chromatography and a total antioxidant performance assay, the present study analyzed the antioxidant variation and antioxidant activity of 36 provitamin A improved maize hybrids and one common yellow maize hybrid., Results: The ranges of major carotenoids in provitamin A carotenoids biofortified maize were zeaxanthin [1.2-13.2 µg g
-1 dry weight (DW)], β-cryptoxanthin (1.3-8.8 µg g-1 DW) and β-carotene (1.3-8.0 µg g-1 DW). The ranges of vitamin E compounds identified in provitamin A carotenoids biofortified maize were α-tocopherol (3.4-34.3 µg g-1 DW), γ-tocopherol (5.9-54.4 µg g-1 DW), α-tocotrienol (2.6-19.5 µg g-1 DW) and γ-tocotrienol (45.4 µg g-1 DW). The ranges of phenolic compounds were γ-oryzanol (0.0-0.8 mg g-1 DW), ferulic acid (0.4-3.6 mg g-1 DW) and p-coumaric acid (0.1-0.45 mg g-1 DW). There was significant correlation between α-tocopherol and cis isomers of β-carotene (P < 0.01). Tocotrienols were correlated with α-tocopherol and γ-oryzanol (P < 0.01)., Conclusion: Genotype was significant in determining the variation in β-cryptoxanthin, β-carotene, α-tocopherol and γ-tocopherol contents (P < 0.01). A genotype × environment interaction was observed for γ-tocopherol content (P < 0.01). © 2016 Society of Chemical Industry., (© 2016 Society of Chemical Industry.)- Published

- Abstract
Objective: To investigate the 1-month effects of an educational programme co-led by peers delivered before treatment on treatment preferences, self-management knowledge and motivation in comparison to usual care., Methods: Adults referred to a community mental health centre were randomised to either a control group (n=48) or a peer co-led educational programme (intervention group, n=45). The programme consisted of an 8-hour group education session followed by an individual pretreatment planning session. The main topics of the educational programme were treatment options, patients' rights, self-management, the importance of patient activation and participation., Results: At 1-month follow-up, a significantly larger proportion of the patients in the intervention group knew which type of treatment they preferred (76.7% vs. 32.5%, p<0.001). The intervention group had significantly higher self-management knowledge (p<0.001). There was no effect on treatment motivation (p=0.543)., Conclusion: At 1-month following the delivery of a pretreatment educational programme, we found that participants' knowledge of treatment preferences and self-management had improved., Practice Implications: Educational interventions co-led by peers can optimise the process of informing and educating outpatients, thereby helping patients to clarify their treatment preferences., (Copyright © 2016 The Authors.

- Abstract
Objective: While there is growing interest in improving patient activation in general medical health services, there are too few randomized controlled trials in mental health settings which show how improvement can be achieved. Using the Patient Activation Measure-13 (PAM-13), we aimed to assess the effect of pre-treatment, peer co-led educational intervention on patient activation. Secondary outcomes included measures of patient satisfaction, well-being, mental health symptoms, motivation, and treatment participation., Methods: Patients from two community mental health centres were randomized to a control group (CG, n=26) receiving treatment as usual, or an intervention group (IG, n=26) consisting of a four-hour group educational seminar (aiming to encourage patients to adopt an active role in their treatment) followed by treatment as usual., Results: Only the IG improved on PAM-13, at one- and four-month follow-ups. The intervention had significant effects on patient satisfaction and treatment participation, compared to CG., Conclusion: Providing pre-treatment, peer co-led education improves patient activation in community mental health care settings., Practice Implications: The use of peers as co-educators may contribute to a different mental health care delivery, ensuring patient activation and participation in treatment. Further studies should examine peers' needs for supervision, challenges for the services, long-term and cost-benefit effects.

- Abstract
Objective: The Patient Activation Measure-13 (PAM-13) has been found useful for assessing patient knowledge, skills and confidence in management of chronic conditions, but the empirical evidence from mental health is sparse. The psychometric properties of PAM in out-patients waiting for treatment in community mental health centers (CMHC) have therefore been examined., Methods: A total of 290 adults from two CMHC completed PAM. An exploratory factor analysis was conducted with 273 patients. Data at baseline and after 4 weeks were used to analyze test-retest reliability (n=60) and to analyze the sensitivity to change (n=51)., Results: The exploratory factor analysis revealed a fit for a two-factor model (Cronbach's α was 0.86 and 0.67), and was assessed for a one-factor model (α=0.87). The test-retest intraclass correlation coefficient was 0.76. Sensitivity to change was good with a statistically significant activation improvement (p<0.001) on patients receiving a peer co-led-educational intervention (Cohen's d was 0.85)., Conclusion: PAM has appropriate and acceptable psychometric properties in mental health settings., Practice Implications: Assessing activation before treatment might be useful for scheduling the delivery of mental health services as well as evaluating educational interventions aimed at improving patient engagement in mental health., (Copyright © 2015 The Authors.

- Abstract
We report the case of a 37-year-old woman with no relevant medical history. She was admitted to the hospital for epigastric pain related with food intake for 4 days; the pain did not improve with symptomatic management. A laparoscopic cholecystectomy due to acute lithiasic cholecystitis was performed. However, after 4 days, postoperative painless jaundice was evident; thus, endoscopic retrograde cholangiopancreatography was performed, which revealed an amputation of intrapancreatic common bile duct, as well as secondary intra- and extrahepatic bile duct dilatation. Brushing of the distal portion of the common bile duct revealed a well-differentiated adenocarcinoma. Therefore, a Whipple procedure with pylorus preservation was performed. Pathologic diagnosis of a papillary in situ adenocarcinoma with two microscopic foci of microinvasion was established. The pathologic Tumor-Node-Metastasis (TNM) stage was pT1, pN0, pM0, R0. The patient is asymptomatic and disease-free 24 months after surgery. In general, adenocarcinomas of the extrahepatic bile ducts are uncommon and have a poor prognosis. However, symptomatic patients with early disease stages are even rarer and can be cured surgically.

- Abstract
It is known that 17β-estradiol (E2) can be transformed by reactions mediated by some oxidoreductases such as laccase in water. Whether or how such reactions can happen in soil is however unknown although they may significantly impact the environmental fate of E2 that is introduced to soil by land application of animal wastes. We herein studied the reaction of E2 in a model soil mediated by laccase, and found that the reaction behaviors differ significantly from those in water partly because of the dramatic difference in laccase stability. We also examined E2 transformation in soil using (14)C-labeling in combination with soil organic matter extraction and size exclusion chromatography, which indicated that applied (14)C radioactivity was preferably bound to humic acids. The study provides useful information for understanding the environmental fate of E2 and for developing a novel soil remediation strategy via enzyme-enhanced humification reactions., (Copyright © 2014 Elsevier Ltd.

- Abstract
Ionophore antibiotics (IPAs) are polyether compounds used in broiler feed to promote growth and control coccidiosis. Most of the ingested IPAs are excreted into broiler litter (BL), a mixture of excreta and bedding material. BL is considered a major source of IPAs released into the environment as BL is commonly used to fertilize agricultural fields. This study investigated IPA biodegradation in BL and soil microcosms, as a process affecting the fate of IPAs in the environment. The study focused on the most widely used IPAs, monensin (MON), salinomycin (SAL), and narasin (NAR). MON was stable in BL microcosms at 24-72% water content (water/wet litter, w/w) and 35-60 °C, whereas SAL and NAR degraded under certain conditions. Factor analysis was conducted to delineate the interaction of water and temperature on SAL and NAR degradation in the BL. A major transformation product of SAL and NAR was identified. Abiotic reaction(s) were primarily responsible for the degradation of MON and SAL in nonfertilized soil microcosms, whereas biodegradation contributed significantly in BL-fertilized soil microcosms. SAL biotransformation in soil microcosms yielded the same product as in the BL microcosms. A new primary biotransformation product of MON was identified in soil microcosms. A field study showed that MON and SAL were stable during BL stacking, whereas MON degraded after BL was applied to grassland. The biotransformation product of MON was also detected in the top soil layer where BL was applied.

- Abstract
Ionophore antibiotics (IPAs) are widely used as coccidiostats in poultry and other livestock industries to promote growth and prevent infections. Because most of the ingested IPAs are excreted in poultry litter, which is primarily applied as grassland fertilizer, a significant amount of IPAs can be released into the litter-soil-water environment. A robust analytical method has been developed to quantify IPAs (monensin (MON), salinomycin (SAL) and narasin (NAR)) in complex environmental compartments including surface runoff, soil and poultry litter, with success to minimize matrix interference. The method for water samples involves solid-phase extraction (SPE) followed by liquid-liquid extraction (LLE) post-clean up steps. The method for solid samples involves bi-solvent LLE. IPAs were detected by HPLC-MS, with optimized parameters to achieve the highest sensitivity. Nigericin (NIG), an IPA not used in livestock industry, is successfully applied and validated as a surrogate standard. The method recoveries were at 92-95% and 81-85% in runoff samples from unfertilized and litter-fertilized fields, respectively. For solids, the method recoveries were at 93-99% in soils, and 79-83% in poultry litter samples. SAL was detected at up to 22mg/kg and MON and NAR at up to 4mg/kg in broiler litter from different farms. Up to 183μg/kg of MON was detected in litter-fertilized soils. All three IPAs were detected in the rainfall runoff from litter-fertilized lands at concentrations up to 9μg/L., (Copyright © 2013 Elsevier B.V. All rights reserved.)
