Abstract
During September and October 2021, a substantial number of Polymerase Chain Reaction (PCR) tests in England processed at a single laboratory were incorrectly reported as negative. We estimate the number of false negative test results issued and investigate the epidemiological impact of this incident. We estimate the number of COVID-19 cases that would have been reported had the sensitivity of the laboratory test procedure not dropped for the period 2 September to 12 October. In addition, by making comparisons between the most affected local areas and comparator populations, we estimate the number of additional infections, cases, hospitalisations and deaths that could have occurred as a result of increased transmission due to false negative test results.We estimate that around 39,000 tests may have been false negatives during this period and, as a direct result of this incident, the most affected areas in the South-West of England could have experienced between 6000 and 34,000 additional reportable cases, with a central estimate of around 24,000 additional reportable cases. Using modelled relationships between key variables, we estimate that this central estimate could have translated to approximately 55,000 additional infections.Each false negative likely led to around 1.5 additional infections. The incident is likely to have had a measurable impact on cases and infections in the affected areas in the South-West of England. IMPACT STATEMENT: These results indicate the significant negative impact of incorrect testing on COVID outcomes; and make a substantial contribution to understanding the impact of testing systems and the need to ensure high accuracy in testing and reporting of results.

Abstract
BACKGROUND Syrian refugees resettled in Turkey show a high prevalence of symptoms of mental disorders. Problem Management Plus (PM+) is an effective psychological intervention delivered by non-specialist health care providers which has shown to decrease psychological distress among people exposed to adversity. In this single-blind pilot randomised controlled trial, we examined the methodological trial procedures of Group PM+ (gPM+) among Syrian refugees with psychological distress in Istanbul, Turkey, and assessed feasibility, acceptability, perceived impact and the potential cost-effectiveness of the intervention. METHODS Refugees with psychological distress (Kessler Psychological Distress Scale, K10 > 15) and impaired psychosocial functioning (World Health Organization Disability Assessment Schedule, WHODAS 2.0 > 16) were recruited from the community and randomised to either gPM+ and enhanced care as usual (E-CAU) (n = 24) or E-CAU only (n = 22). gPM+ comprised of five weekly group sessions with eight to ten participants per group. Acceptability and feasibility of the intervention were assessed through semi-structured interviews. The primary outcome at 3-month follow-up was symptoms of depression and anxiety (Hopkins Symptoms Checklist-25). Psychosocial functioning (WHODAS 2.0), symptoms of posttraumatic stress disorder and self-identified problems (Psychological Outcomes Profiles, PSYCHLOPS) were included as secondary outcomes. A modified version of the Client Service Receipt Inventory was used to document changes in the costs of health service utilisation as well as productivity losses. RESULTS There were no barriers experienced in recruiting study participants and in randomising them into the respective study arms. Retention in gPM+ was high (75%). Qualitative analyses of the interviews with the participants showed that Syrian refugees had a positive view on the content, implementation and format of gPM+. No adverse events were reported during the implementation. The study was not powered to detect an effect. No significant difference between gPM+ and E-CAU group on primary and secondary outcome measures, or in economic impacts were found. CONCLUSIONS gPM+ delivered by non-specialist peer providers seemed to be an acceptable, feasible and safe intervention for Syrian refugees in Turkey with elevated levels of psychological distress. This pilot RCT sets the stage for a fully powered RCT. TRIAL REGISTRATION ClinicalTrials.gov Identifier NCT03567083 ; date: 25/06/2018.

Abstract
Abstract
Background
Common mental health problems are prevalent among refugee minors and impair their daily functioning. Due to various barriers such as lack of culturally appropriate treatments, waiting lists, and stigma they have limited access to care. Problem Management Plus (PM+) was developed by the World Health Organization to address these barriers. PM+ is transdiagnostic, delivered by non-professional helpers, and consists of 5 sessions of problem-solving skills, behavioural activation and stress management. PM+ is effective in reducing adults' distress and improve functioning. We aimed to adapt PM+ for refugee minors and add an emotional processing module to target symptoms of posttraumatic stress disorder.
Methods
We culturally and contextually adapted PM+ for use in Syrian, Eritrean and Afghan refugee minors (age 16-18 years). Data were collected through: 1) free list interviews with Syrian, Eritrean and Afghan refugee minors (n = 30), 2) key informant interviews with knowledgeable refugees (n = 6), professionals (n = 6), policy makers (n = 6) and 3) focus group discussions (n = 24). Data were analysed in ATLAS.ti through inductive and deductive framework analysis.
Results
The interviews with youth revealed daily life problems around the following themes: language, family and peers, and substance use. The overall results suggested the need for culture- and age-specific adaptations of 1) the PM+ manual content (language, metaphors, illustrations) and 2) intervention delivery (modality, content and presentation of the trauma processing module, and duration).
Conclusions
This study led to specific adaptations of PM+ for refugee adolescents to be used in two randomized controlled trials in the Netherlands and Sweden.
Key message
Refugee minors face numerous barriers reaching mental health care. Scalable, culturally adapted psychological interventions should be developed and evaluated to address common mental disorders in refugee youth.

Abstract
Abstract
Background
Refugees and their children are exposed to many distressing events, including detention in refugee camps. Not surprisingly, refugees are at high risk for common mental disorders. A major barrier to addressing mental health problems in refugees is that most host countries lack sufficient mental health specialists to provide high-intensity treatments.
A recent trend has focused on training non-specialists to deliver simple psychosocial programs to those with distress. One such program is Problem Management Plus (PM+) which was developed by the World Health Organization; it comprises 5 small-group sessions that teach behavioural skills to reduce distress. This study reports the first evaluation of group PM+ in a refugee camp. We investigated the extent to which PM+ provided to adult Syrian refugees can benefit their children.
Methods
480 Adult Syrian refugees in the Azraq Refugee Camp were randomized to either PM+ or Treatment as Usual (TAU). Participants were independently assessed prior to the program, immediately following the program, and 3 months later. Outcome variables included anxiety, depression, functioning, posttraumatic stress, and grief and parenting behaviours. Children's psychological wellbeing was assessed in one child of each participant.
Results
Of the 650 adult refugees were screened in the camp, 96% met the cut-off for psychological distress and 76% met criteria for functional impairment. 480 participants were randomized to PM+ or TAU. The baseline assessment indicated 85% of refugees met criteria for depression, 84% met criteria for anxiety, and 84% met criteria for posttraumatic stress disorder. The 3-month assessment will be presented following linear mixed modelling to determine the relative gains made by refugees and their children in PM+ and TAU.
Conclusions
These findings will be discussed in terms of implementation of scalable programs in refugee settings, and specifically how these can benefit participants and their children.

Abstract
Exhaust flows from coal-fired electricity-generating plants are determined by averaging flue gas velocities measured at prescribed points in the stack cross section. These velocity measurements are made using EPA-approved differential pressure probes such as the 2-hole S-probe or the 5-hole spherical probe. Measurements using the more accurate 5-hole spherical probes require a time-consuming rotation (or nulling) of the probe to find the yaw angle. We developed a time-saving non-nulling technique using a spherical probe that measures all 3 components of velocity and therefore provides better accuracy than an S-probe. We compared the non-nulling technique with the EPA Method 2F nulling technique at both high (16 m/s) and low (7 m/s) loads in a coal-fired powerplant smokestack. Their excellent mutual agreement (within 0.3% of the flow) demonstrates that the non-nulling technique accurately measures flue gas flows.Implications: Accurate flow measurements are critical for quantifying the levels of greenhouse gases emitted from coal-fired power plant smokestacks. Flow measurement accuracy derives from the annual calibration of stack flow monitors. Calibrations are performed using EPA sanctioned pitot traverse methods called the flow relative accuracy test audit (RATA). This study demonstrates the viability of a new pitot traverse method, herein called the Non-Nulling Method. Testing in a coal-fired power plant stack showed that the new method is 5 times faster to implement than the most accurate EPA pitot traverse method (i.e., Method 2F), yet gives the same or better accuracy.

Abstract
Abstract
A collaborative study was conducted in 15 laboratories to evaluate 2 different techniques for enumerating Bacillus cereus in foods. A direct plating technique using mannitol-egg yolk-polymyxin agar and a most probable number (MPN) technique using trypticase-soy-polymyxin broth were compared for the enumeration of high and low populations of B. cereus in mashed potatoes. The collaborative results showed that the overall mean recovery obtained with the low population level was essentially the same by both techniques. However, the overall mean recovery was significantly higher by the direct plating technique at the high population level. A statistical evaluation of the data also showed that the direct plating technique had better repeatability and reproducibility than did the MFN technique at both the high and low population levels. These results suggest that the MPN technique is suitable for examining foods containing low populations of B. cereus, but that the direct plating technique is preferable for foods that contain a high population of this organism. The confirmatory technique used in the proposed method is reliable for presumptive identification of isolates as B. cereus. The method has been adopted as official first action.

Abstract
Five foods types were analyzed by the Assurance EHEC (Escherichia coli 0157:H7) enzyme immunoassay (EIA) and by the Bacteriological Analytical Manual (BAM) culture method. Each sample of each food type at each inoculation level was simultaneously analyzed by both methods. A total of 21 laboratories representing state and federal government agencies and private industry in the United States and Canada participated. Samples were inoculated with E. coli 0157:H7, except for one lot of poultry that was naturally contaminated. A total of 1304 samples and controls were analyzed and confirmed, of which 473 were positive and 818 were negative by both methods. Thirteen samples were positive by BAM but negative by EIA. Because of the study design, it was not possible for the BAM method to produce false-negative or falsepositive results. The Assurance method for detection of E. coli OI57:H7 in selected foods has been adopted first action by AOAC INTERNATIONAL.

Abstract
Five foods representative of a variety of food products were analyzed by the Visual Immunoprecipitate Assay (VIP) and the Bacteriological Analytical Manual (BAM) culture method for the presence of Escherichia coli 0157: H7. A total of 21 laboratories representing state and federal government agencies, as well as private industry, in the United States and Canada participated. Food types were inoculated with strains of E. coli 0157:H7, with the exception of one lot of poultry, which was naturally contaminated. During this study, a total of 1377 samples and controls were analyzed and confirmed, of which 508 were positive and 867 were negative by both methods. Two samples were positive by BAM and negative by VIP. Because of the study design, it was not possible for the BAM method to produce false-negative or false-positive results.

Abstract
OBJECTIVE Mood disorders are strongly associated with suicide, the prevention of which is predicated on timely detection of suicidal activity (ideation, behaviour). Building on our previous work, we sought to determine the nature of neural responses to an emotional-cognitive task in patients with varying degrees of suicidal activity. METHOD Seventy-nine patients with mood disorders were assessed clinically and scanned using fMRI. Neural responses to an Emotional Face-Word Stroop task were compared with 66 healthy controls. We identified regions of interest from seven key networks and examined responses to incongruent stimuli (Happy face-'Sad' word; Sad face-'Happy' word). RESULTS In comparison with healthy controls, patients had differential activity during both incongruent conditions. When examining for associations with suicidal activity within the patient group, those with higher scores had decreased default mode network activity for Happy face-'Sad' word manipulation, and increased basal ganglia network activity for Sad face-'Happy' word manipulation, after controlling for patient characteristics. CONCLUSION The fMRI findings suggest that suicidal activity in patients with mood disorders may be underpinned by cognitive-emotional deficits. These findings have implications for future suicide research and for achieving a deeper understanding of suicidal activity that may ultimately inform clinical detection and management.

Abstract
This paper presents a case study of Beyond Bushfires, a large, multisite, mixed method study of the psychosocial impacts of major bushfires in Victoria, Australia. A participatory approach was employed throughout the study which was led by a team of academic investigators in partnership with service providers and government representatives and used on-site visits and multiple methods of communication with communities across the state to inform decision-making throughout the study. The ethics and impacts of conducting and adapting the approach within a post-disaster context will be discussed in reference to theories and models of participatory health research. The challenges of balancing local interests with state-wide implications will also be explored in the description of the methods of engagement and the study processes and outcomes. Beyond Bushfires demonstrates the feasibility of incorporating participatory methods in large, post-disaster research studies and achieving rigorous findings and multilevel impacts, while recognising the potential for some of the empowering aspects of the participatory experience to be reduced by the scaled-up approach.

Abstract
BACKGROUND Depression is a commonly occurring disorder linked to diminished role functioning and quality of life. The development of treatments that overcome barriers to accessing treatment remains an important area of clinical research as most people delay or do not receive treatment at an appropriate time. The workplace is an ideal setting to roll-out an intervention, particularly given the substantial psychological benefits associated with remaining in the workforce. Mobile health (mhealth) interventions utilising smartphone applications (apps) offer novel solutions to disseminating evidence based programs, however few apps have undergone rigorous testing. The present study aims to evaluate the effectiveness of a smartphone app designed to treat depressive symptoms in workers. METHODS The present study is a multicentre randomised controlled trial (RCT), comparing the effectiveness of the intervention to that of an attention control. The primary outcome measured will be reduced depressive symptoms at 3 months. Secondary outcomes such as wellbeing and work performance will also be measured. Employees from a range of industries will be recruited via a mixture of targeted social media advertising and Industry partners. Participants will be included if they present with likely current depression at baseline. Following baseline assessment (administered within the app), participants will be randomised to receive one of two versions of the Headgear application: 1) Intervention (a 30-day mental health intervention focusing on behavioural activation and mindfulness), or 2) attention control app (mood monitoring for 30 days). Participants will be blinded to their allocation. Analyses will be conducted within an intention to treat framework using mixed modelling. DISCUSSION The results of this trial will provide valuable information about the effectiveness of mhealth interventions in the treatment of depressive symptoms in a workplace context. TRIAL REGISTRATION The current trial is registered with the Australian and New Zealand Clinical Trials Registry ( ACTRN12617000547347 , Registration date: 19/04/2017).

Abstract
UNLABELLED WHAT IS KNOWN ON THE SUBJECT?: Resilience is an ability and a process that allows an individual to develop positive adaptation despite challenges and adversities. Many military veterans returning to college after their military service have difficulty transitioning to civilian life. Although some research exists that explores factors related to the resilience of college student veterans, limited theoretical descriptions exist that explain how student veterans construct resilience, and how resilience is enacted and enhanced in their academic and personal (non-academic) lives. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: The resilience of student veterans involves a complex process of transitioning from military to civilian life and an iterative journey between positive adaptation and transient perturbations. Student veterans' resilience is a result of integrating and resolving various aspects of their academic and personal challenges. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Nurses can apply this grounded theory as a practical framework for equipping student veterans with effective strategies to develop and enhance resilience. Nurses can employ a holistic approach of care in their interactions with military veterans and student veterans that includes fostering psychological resilience, helping to manage their multiple non-academic responsibilities and supporting their academic success. ABSTRACT Introduction Adjusting to college life is one of the most difficult experiences in a military veteran's transition to civilian life. Many military veterans returning to college not only encounter academic challenges, but also deal with physical and psychiatric disabilities, loss of military camaraderie and social disconnect. These often negatively affect their personal and academic lives. Hence, it is important to explore resilience to best support student veterans as they transition from military to civilian life. Aim The aim of this study was to explore how student veterans construct and enact resilience within their personal and academic lives. Method Using constructivist grounded theory methodology, in-depth individual interviews were conducted with 20 military veterans enrolled as undergraduate students at a U.S. university. Results The process of "integrating," which represents student veterans' construction and enactment of resilience, was the core category. This category has three subcategories: (1) the aspects; (2) the expressions; and (3) the enactments of resilience. Implications for practice Nurses can use this grounded theory as the practical framework for their interactions with military veterans, and more particularly with supporting student veterans in their academic lives, in their personal lives and in the transition from military to civilian life.

Abstract
BACKGROUND Therapeutic drug monitoring (TDM) in inflammatory bowel disease (IBD) patients receiving anti-tumour necrosis factor (TNF) agents can help optimise outcomes. Consensus statements based on current evidence will help the development of treatment guidelines. AIM To develop evidence-based consensus statements for TDM-guided anti-TNF therapy in IBD. METHODS A committee of 25 Australian and international experts was assembled. The initial draft statements were produced following a systematic literature search. A modified Delphi technique was used with 3 iterations. Statements were modified according to anonymous voting and feedback at each iteration. Statements with 80% agreement without or with minor reservation were accepted. RESULTS 22/24 statements met criteria for consensus. For anti-TNF agents, TDM should be performed upon treatment failure, following successful induction, when contemplating a drug holiday and periodically in clinical remission only when results would change management. To achieve clinical remission in luminal IBD, infliximab and adalimumab trough concentrations in the range of 3-8 and 5-12 μg/mL, respectively, were deemed appropriate. The range may differ for different disease phenotypes or treatment endpoints-such as fistulising disease or to achieve mucosal healing. In treatment failure, TDM may identify mechanisms to guide subsequent decision-making. In stable clinical response, TDM-guided dosing may avoid future relapse. Data indicate drug-tolerant anti-drug antibody assays do not offer an advantage over drug-sensitive assays. Further data are required prior to recommending TDM for non-anti-TNF biological agents. CONCLUSION Consensus statements support the role of TDM in optimising anti-TNF agents to treat IBD, especially in situations of treatment failure.

Abstract
Depression and anxiety disorders are the leading cause of sickness absence and long-term work incapacity in most developed countries. The present study aimed to carry out a systematic meta-review examining the effectiveness of workplace mental health interventions, defined as any intervention that a workplace may either initiate or facilitate that aims to prevent, treat or rehabilitate a worker with a diagnosis of depression, anxiety or both. Relevant reviews were identified via a detailed systematic search of academic and grey literature databases. All articles were subjected to a rigorous quality appraisal using the AMSTAR assessment. Of the 5179 articles identified, 140 studies met the inclusion criteria, of which 20 were deemed to be of moderate or high quality. Together, these reviews analysed 481 primary research studies. Moderate evidence was identified for two primary prevention interventions; enhancing employee control and promoting physical activity. Stronger evidence was found for CBT-based stress management although less evidence was found for other secondary prevention interventions, such as counselling. Strong evidence was also found against the routine use of debriefing following trauma. Tertiary interventions with a specific focus on work, such as exposure therapy and CBT-based and problem-focused return-to-work programmes, had a strong evidence base for improving symptomology and a moderate evidence base for improving occupational outcomes. Overall, these findings demonstrate there are empirically supported interventions that workplaces can utilize to aid in the prevention of common mental illness as well as facilitating the recovery of employees diagnosed with depression and/or anxiety.

Abstract
BACKGROUND Dissociative reactions in post-traumatic stress disorder (PTSD) have been regarded as strategic responses that limit arousal. Neuroimaging studies suggest distinct prefrontal responses in individuals displaying dissociative and hyperarousal responses to threat in PTSD. Increased prefrontal activity may reflect enhanced regulation of limbic arousal networks in dissociation. If dissociation is a higher-order regulatory response to threat, there may be differential responses to conscious and automatic processing of threat stimuli. This study addresses this question by examining the impact of dissociation on fear processing at different levels of awareness. METHOD Functional magnetic resonance imaging (fMRI) with a 1.5-T scanner was used to examine activation to fearful (versus neutral) facial expressions during consciously attended and non-conscious (using backward masking) conditions in 23 individuals with PTSD. Activation in 11 individuals displaying non-dissociative reactions was compared to activation in 12 displaying dissociative reactions to consciously and non-consciously perceived fear stimuli. RESULTS Dissociative PTSD was associated with enhanced activation in the ventral prefrontal cortex for conscious fear, and in the bilateral amygdala, insula and left thalamus for non-conscious fear compared to non-dissociative PTSD. Comparatively reduced activation in the dissociative group was apparent in dorsomedial prefrontal regions for conscious fear faces. CONCLUSIONS These findings confirm our hypotheses of enhanced prefrontal activity to conscious fear and enhanced activity in limbic networks to non-conscious fear in dissociative PTSD. This supports the theory that dissociation is a regulatory strategy invoked to cope with extreme arousal in PTSD, but this strategy appears to function only during conscious processing of threat.

Abstract
In humans and nonhuman primates, the structure and function of frontal cortical regions of the brain are not completely developed until early adulthood. How this cortical development affects cognitive function continues to be elucidated. To that end, this experiment tested the ability of juvenile and adult rhesus monkeys to perform a cognitive task that is dependent upon intact frontal cortical function for optimal performance. Twenty-four juvenile (mean age 2.3 years) and 16 adult (mean age 10.3 years) rhesus monkeys were tested on the Cambridge Neuropsychological Test Automated Battery intradimensional/extradimensional set-shifting (ID/ED) task. Performance on the ID/ED task has been shown to be dependent upon frontal cortical function in both humans and nonhuman primates. Compared with adults, juveniles were impaired on the reversal of simple discrimination, intradimensional shift, reversal of intradimensional shift, and the extradimensional shift stages of the task. These results indicate juveniles committed more perseverative errors and more errors on the set-formation and set-shifting components of the ID/ED task. The developmental stage of the juvenile monkeys corresponds to roughly 5 to 6-year-old children, and these results are consistent with performance of human children and adults on similar ID/ED tests and on several other tests of attentional set-shifting or attentional flexibility. Furthermore, these results are consistent with the ongoing development of frontal cortical structures relating to ongoing cognitive development in nonhuman primates.

Abstract
This communication integrates the purported role of cholesterol and statins in Alzheimer's disease (AD) with recent data. Meta-analysis of association studies relevant to AD indicates that apolipoprotein (apo)E4 is the only cholesterol-related polymorphism that shows clear association with AD. This suggests that the effect of apoE4 on the pathophysiology of AD occurs via a mechanism that is not directly related to cholesterol, such as fibrillization of Abeta. Despite the lack of genetic association, cholesterol and statins clearly modulate amyloid precursor protein (APP) processing in cell culture and animal models. Statins appear to act by a pleiotropic mechanism, involving both cholesterol (via lipid rafts) and isoprenylation. The pleiotropic mechanism of statin action clarifies conflicting data from clinical studies, where statins exert an action on Abeta and AD that might be dose dependent because of actions on both cholesterol and isoprenylation. Reduced isoprenylation can also inhibit inflammation. Our own studies of brains from Alzheimer subjects +/- statins indicate that statins inhibit inflammation in humans but might not reduce cerebral Abeta load. These results suggest that the primary action of statins in humans with AD might be to reduce inflammation rather than decrease Abeta load.
