Resistance to COVID-19 vaccination has increased in Ireland and the United Kingdom during the pandemic.

OBJECTIVES: Hesitance and resistance to COVID-19 vaccination poses a serious challenge to achieving adequate vaccine uptake in the general population. Cross-sectional data from the early months of the pandemic indicates that approximately one-third of adults in multiple nations are hesitant or resistant to a vaccine for COVID-19. Using longitudinal data, we tracked changes in attitudes to COVID-19 vaccination during the pandemic. STUDY DESIGN: This is a quantitative, longitudinal design. METHOD: Nationally representative samples of the adult general population of the Republic of Ireland (N = 1041) and the United Kingdom (N = 2025) were assessed for their attitudes towards COVID-19 vaccination at three points from March to August 2020. RESULTS: Statistically significant increases in resistance to COVID-19 vaccination were observed in Irish (from 9.5% to 18.1%) and British (from 6.2% to 10%) adults. CONCLUSION: Resistance to vaccination has significantly increased in two European nations as the pandemic has progressed. Growing resistance to COVID-19 vaccination will pose a challenge to public health officials responsible for ensuring sufficient vaccine coverage.

Measuring ICD-11 adjustment disorder: the development and initial validation of the International Adjustment Disorder Questionnaire.

BACKGROUND: Adjustment disorder (AjD) is one of the most frequently used diagnoses in psychiatry but a diagnostic definition for AjD was only introduced in release of the ICD-11. This study sought to develop and validate a new measure operationalizing the ICD-11's narrative description of AjD, and to determine the current rate of people meeting the symptoms indicative of AjD in the general population of the Republic of Ireland. METHODS: The International Adjustment Disorder Questionnaire (IADQ) was constructed to measure the core diagnostic criteria of ICD-11 AjD: stressor exposure, preoccupations with, and failure to adapt to, the stressor, timing of symptom onset, and functional impairment. A nationally representative sample (N = 1,020) of adults from Ireland completed the IADQ. RESULTS: Confirmatory factor analysis supported construct validity and the reliability estimates were excellent. The IADQ correlated strongly with depression, anxiety, and posttraumatic stress. The criteria were met by 7.0% of the sample, adjusted for other exclusionary disorders. DISCUSSION: The IADQ is a measure based on the ICD-11's description and produces reliable scores, however it should not be used for clinical assessment until validated with clinical interviews.

Anxiety and depression in the Republic of Ireland during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic in Ireland resulted in a nationwide quarantine on March 27, 2020. This study represents the first assessment of rates of anxiety and depression in the general population of Ireland during the pandemic. AIMS: Our first aim was to estimate the probable prevalence rates of generalized anxiety disorder (GAD) and depression and to identify sociodemographic risk factors associated with screening positive for GAD or depression. Our second aim was to determine if COVID-19 related anxiety was highest amongst those in society at greatest risk of morality from COVID-19. METHOD: Self-report data were collected from a nationally representative Irish sample (N = 1041) online between March 31 and April 5; the first week of the nationwide quarantine measures. Recognized cut-off scores on the GAD-7 and PHQ-9 were used to estimate rates of GAD and depression. Correlates of screening positive for GAD or depression were assessed using logistic regression analysis. RESULTS: GAD (20.0%), depression (22.8%) and GAD or depression (27.7%) was common. Screening positive for GAD or depression was associated with younger age, female sex, loss of income due to COVID-19, COVID-19 infection and higher perceived risk of COVID-19 infection. Citizens aged 65 and older had significantly higher levels of COVID-19 related anxiety than adults aged 18-34. CONCLUSIONS: Initial results from this multi-wave study monitoring changes in population anxiety and depression throughout the pandemic indicate that GAD and depression were common experiences in the population during the initial phase of the COVID-19 pandemic.

A comparison of DSM-5 and ICD-11 PTSD prevalence, comorbidity and disability: an analysis of the Ukrainian Internally Displaced Person's Mental Health Survey.

OBJECTIVE: Recently, the American Psychiatric Association (DSM-5) and the World Health Organization (ICD-11) have both revised their formulation of post-traumatic stress disorder (PTSD). The primary aim of this study was to compare DSM-5 and ICD-11 PTSD prevalence and comorbidity rates, as well as the level of disability associated with each diagnosis. METHOD: This study was based on a representative sample of adult Ukrainian internally displaced persons (IDPs: N = 2203). Post-traumatic stress disorder prevalence was assessed using the PTSD Checklist for DSM-5 and the International Trauma Questionnaire (ICD-11). Anxiety and depression were measured using the Generalized Anxiety Disorder Scale and the Patient Health Questionnaire-Depression. Disability was measured using the WHO Disability Assessment Schedule 2.0. RESULTS: The prevalence of DSM-5 PTSD (27.4%) was significantly higher than ICD-11 PTSD (21.0%), and PTSD rates for females were significantly higher using both criteria. ICD-11 PTSD was associated with significantly higher levels of disability and comorbidity. CONCLUSION: The ICD-11 diagnosis of PTSD appears to be particularly well suited to identifying those with clinically relevant levels of disability.

ICD-11 PTSD and complex PTSD amongst Syrian refugees in Lebanon: the factor structure and the clinical utility of the International Trauma Questionnaire.

OBJECTIVE: Support for ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) is growing; however, few studies include refugees or examine the clinical utility of PTSD/CPTSD classifications. This study sought to provide the first evaluations of (i) the factor structure of ICD-11 PTSD/CPTSD amongst refugees in the Middle East; and (ii) the clinical utility of the International Trauma Questionnaire (ITQ) to identify PTSD/CPTSD in a humanitarian context. METHOD: Participants were 112 treatment-seeking Syrian refugees living in Lebanon. Factorial validity was assessed using confirmatory factor analysis (CFA) based on responses to the ITQ. Clinical utility of the ITQ was assessed through semi-structured interviews with six Lebanese psychotherapists. RESULTS: Complex PTSD (36.1%) was more common than PTSD (25.2%), and no sex or age differences were observed at the prevalence or symptomatic levels. CFA results supported a two-factor higher-order model consistent with ICD-11 PTSD/CPTSD. Qualitative findings indicated that the ITQ is generally positively regarded, with some limitations and suggested modifications noted. CONCLUSION: This is the first study to support the ICD-11 PTSD/CPTSD amongst refugees in the Middle East and the clinical utility of the ITQ in a humanitarian context. Findings support the growing evidence for the cross-cultural applicability of ICD-11 PTSD/CPTSD.

Mechanism involved in interleukin-21-induced phagocytosis in human monocytes and macrophages.

The interleukin (IL)-21/IL-21 receptor (R) is a promising system to be exploited for the development of therapeutic strategies. Although the biological activities of IL-21 and its cell signalling events have been largely studied in immunocytes, its interaction with human monocytes and macrophages have been neglected. Previously, we reported that IL-21 enhances Fc gamma receptor (FcRγ)-mediated phagocytosis in human monocytes and in human monocyte-derived macrophages (HMDM) and identified Syk as a novel molecular target of IL-21. Here, we elucidate further how IL-21 promotes phagocytosis in these cells. Unlike its ability to enhance phagocytosis of opsonized sheep red blood cells (SRBCs), IL-21 did not promote phagocytosis of Escherichia coli and zymosan by monocytes and did not alter the cell surface expression of CD16, CD32 and CD64. In HMDM, IL-21 was found to enhance phagocytosis of zymosan. In addition, we found that IL-21 activates p38, protein kinase B (Akt), signal transducer and activator of transcription (STAT)-1 and STAT-3 in monocytes and HMDM. Using a pharmacological approach, we demonstrate that IL-21 enhances phagocytosis by activating some mitogen-activated protein kinases (MAPKs) and phosphoinositide 3-kinase (PI3K)-Akt and Janus kinase (JAK)-STAT pathways. These results obtained in human monocytes and macrophages have to be considered for a better exploitation of the IL-21/IL-21R system for therapeutic purposes.

From PERFORM to PERFORM2Scale: Lessons from scaling-up a health management strengthening intervention to support Universal Health Coverage in three African countries.

Strengthening management and leadership competencies among district and local health managers has emerged as a common approach for health systems strengthening and to achieve Universal Health Coverage (UHC). While the literature is rich with localised examples of initiatives that aim to strengthen the capacity of district or local health managers, particularly in sub-Saharan Africa, considerably less attention is paid to the science of how to scale-up these initiatives. The aim of this paper is thus to examine the process of scaling-up a management strengthening intervention (MSI) and identify new knowledge and key lessons learned that can be used to inform the scale-up process of other complex health interventions, in support of UHC. Qualitative methods were used to identify lessons learned from scaling-up the MSI in Ghana, Malawi and Uganda. We conducted 14 interviews with district health management team members, three scale-up assessments with 20 scale-up stakeholders, and three reflection discussions with 11 research team members. We also kept records of activities throughout MSI and scale-up implementation. Data was recorded, transcribed, and analysed against the Theory of Change to identify both scale-up outcomes and the factors affecting these outcomes. The MSI was ultimately scaled-up across 27 districts. Repeated MSI cycles over time were found to foster greater feelings of autonomy among district health management teams (DHMTs) to address longstanding local problems, a more innovative use of existing resources without relying on additional funding, and improved teamwork. The use of 'resource teams' and the emergence of MSI 'champions', were both instrumental in supporting scale-up efforts. Challenges to the sustainability of the MSI include limited government buy-in and lack of sustained financial investment.

Are posttraumatic stress disorder (PTSD) and complex-PTSD distinguishable within a treatment-seeking sample of Syrian refugees living in Lebanon?

BACKGROUND: The World Health Organization will publish its 11th revision of the International Classification of Diseases (ICD-11) in 2018. The ICD-11 will include a refined model of posttraumatic stress disorder (PTSD) and a new diagnosis of complex PTSD (CPTSD). Whereas emerging data supports the validity of these proposals, the discriminant validity of PTSD and CPTSD have yet to be tested amongst a sample of refugees. METHODS: Treatment-seeking Syrian refugees (N = 110) living in Lebanon completed an Arabic version of the International Trauma Questionnaire; a measure specifically designed to capture the symptom content of ICD-11 PTSD and CPTSD. RESULTS: In total, 62.6% of the sample met the diagnostic criteria for PTSD or CPTSD. More refugees met the criteria for CPTSD (36.1%) than PTSD (25.2%) and no gender differences were observed. Latent class analysis results identified three distinct groups: (1) a PTSD class, (2) a CPTSD class and (3) a low symptom class. Class membership was significantly predicted by levels of functional impairment. CONCLUSION: Support for the discriminant validity of ICD-11 PTSD and CPTSD was observed for the first time within a sample of refugees. In support of the cross-cultural validity of the ICD-11 proposals, the prevalence of PTSD and CPTSD were similar to those observed in culturally distinct contexts.
