Abstract
OBJECTIVE Using a dressing that expands and conforms to the wound bed upon exudate absorption is one of the best ways to promote wound healing. While many products claim wound bed conformability, no externally replicated or verified test methodology had been developed to quantify a wound dressing's ability to conform to the wound bed. The Relative Swelling Rise (RSR) test methodology was developed to measure the relative swelling rise of foam dressings upon fluid absorption, and offers a quantifiable and easily replicated method to measure wound bed conformability. METHOD The RSR test method was developed, validated and reliability tested by Coloplast A/S, Denmark. External replication was provided by ALS Odense, Denmark (previously DB Lab). Circular fences provide a fixed diameter to apply and contain the fluid and prevent horizontal spreading in the test set-up. The swelling height is quantified relative to the fence's inner diameter, i.e., the ratio alpha (α), and allows evaluation of a material's ability to conform to the wound bed. RESULTS Biatain Silicone foam products (n=3, Coloplast A/S, Denmark) were tested, all afforded an average α-ratio from 0.30 to 0.60. The relative standard deviations were between 1-3%, demonstrating the strength of the test. Robustness of the methodology was demonstrated through the internal validation study, the reliability study, and both an internal and external replication study, as well as a systematic literature review and expert review of the construct, content, criterion and generalisability of the method. CONCLUSION Having a validated, effective and easily replicable testing method to quantify wound bed conformability of foam dressings is an important step towards achieving better healing outcomes.

Abstract
BACKGROUND Leakage is the number one concern for people with an ostomy. The 2019 Ostomy Life Study, a global study of more than 5000 ostomates, showed that 92% of people living with a stoma worry about leakage. Getting the right stoma appliance for each patient is key to increasing patient quality of life. AIM The study was designed to assess the use of the Peristomal Body Profile Assessment Tool in helping choose the most appropriate stoma products for a given patient, decreasing incidents of leakage and peristomal skin complications. METHODS A multi-centre (33 sites, 147 patients) low-interventional clinical investigation was conducted in which the use of the Peristomal Body Profile Assessment Tool was evaluated as a tool to reduce incidents of leakage, increase peristomal skin health and increase patient quality of life. A focus group of randomised participating clinicians (n=16) was held to explore the audit results. RESULTS The assessment tool most often took between 2 and 5 minutes to complete. It supported clinicians in selecting the right appliance for each patient, avoiding leakages and preventing associated peristomal skin complications. The assessment tool helped improve the accuracy and quality of documentation in the patients' medical/nursing notes, increasing the quality and continuity of care. Participants reported that using the assessment tool helped reduce care costs by reducing the need for product changes, supporting product usage and return patient visits. CONCLUSION Use of the Peristomal Body Profile Assessment Tool helped clinicians choose the most appropriate stoma appliance the first time, resulting in patients having healthier peristomal skin, fewer leakages, more confidence in their stoma appliance and a higher quality of life.

Abstract
BACKGROUND AND HYPOTHESIS Impaired insight into one's illness is common in first episode psychosis (FEP), is associated with worse symptoms and functioning, and predicts a worse course of illness. Despite its importance, little research has examined the effects of early intervention services (EIS) on insight. DESIGNS This paper evaluated the impact of EIS (NAVIGATE) on insight compared to usual community care (CC) in a large cluster randomized controlled trial. Assessments were conducted at baseline and every 6 months for 2 years. RESULTS A multilevel regression model including all time points showed a significant time by treatment group interaction (P < .001), reflecting greater improvement in insight for NAVIGATE than CC participants. Impaired insight was related to less severe depression but worse other symptoms and functioning at baseline for the total sample. At 6 months, the same pattern was found within each group except insight was no longer associated with depression among NAVIGATE participants. Impaired insight was more strongly associated with worse interpersonal relationships at 6 months in NAVIGATE than in CC, and changes in insight from baseline to 6 months were more strongly correlated with changes in relationships in NAVIGATE than CC. CONCLUSIONS The NAVIGATE program improved insight significantly more than CC. Although greater awareness of illness has frequently been found to be associated with higher depression in schizophrenia, these findings suggest EIS programs can improve insight without worsening depression in FEP. The increased association between insight and social relationships in NAVIGATE suggests these 2 outcomes may synergistically interact to improve each other in treatment.

Abstract
A study involving over 2000 stoma care nurses in the development of best practice guidelines for the assessment of peristomal body profiles, patient engagement and patient follow-up was conducted in 2018. The study was designed to develop guidelines for stoma care treatment and product selection and to decrease the evidence to implementation gap. The project built on research evidence from a literature review of 77 articles. The results of the literature review were then used to inform a series of Delphi surveys sent out to stoma care nurses through Association and industry list-serves in 11 languages. The Delphi surveys were followed by a face2face professionally facilitated discussions among nurse-research experts. The project concluded with a facilitated consensus dialogue among 960 stoma care nurses from 25 countries, resulting in an implementation plan to ensure the guidelines become a normal part of routine patient care. The study resulted in a set of medical practice guidelines for stoma care nurses, designed to improve patient outcomes and patient quality of life, that were accepted and adopted into routine medical practice across 25 countries. This article describes the study and how the process used, coined the 'Modified Delphi Process' by the process designer, led to faster implementation than is generally experienced in the medical community.

Abstract
STUDY DESIGN Prospective observational study. OBJECTIVES A tool to help decision-making tool for Neurogenic Bowel Dysfunction (NBD) in individuals with SCI is needed. We present a project to create and validate a new tool, the Monitoring Efficacy of NBD Treatment On Response (MENTOR), and to determine its level of concordance with decisions made by experienced clinicians in the field. SETTING UK, Denmark, USA, Italy, The Netherlands, Germany. METHODS The first phase was creation of the tool through a modified Delphi process. The second phase was the validation, wherein individuals with spinal cord injury with NBD were asked to complete the MENTOR tool immediately prior to clinic consultation. From the responses to the questionnaire of the tool, each participant was allocated into one of three categories reflecting the possible therapeutic recommendations ("recommend change", "further discussion" and "monitoring"). An expert clinician then assessed the participant, blinded to MENTOR results, and made an independent treatment decision. RESULTS A total of 248 MENTOR forms were completed. Strong agreement was found when the MENTOR tool recommended monitoring (92%) or treatment change (83%); the lowest concordance when the decision was for the "further discussion" option (59%). Patient acceptability was reported by 97% of individuals. CONCLUSIONS MENTOR is an easy to use tool to monitor the treatment of NBD and determinate progression through the clinical pathway. This validation study shows good correspondence between expert clinician opinion and MENTOR result. The tool has potential to be used in other patient groups, following further studies.

Abstract
Medical professionals follow evidence-based practice guidelines to achieve effective patient outcomes. Traditionally, to develop guidelines, a small group of experts examine evidence then agree on a set of statements, which are then published in journals. However, more than 7000 primary care journal articles are published monthly. This study examined a different way of drawing up practice guidelines, which involved large numbers of nurses from different countries directly in developing then disseminating the guidelines to speed up acceptance and the implementation of best practice. The results were consensus-based best practice guidelines for the treatment of patients with ostomies, which have received a high level of acceptance and enthusiasm from practitioners in 27 countries.

Abstract
Abstract
Objective
Multilinguals show greater subcortical activation during language tasks than monolinguals. Among multilinguals, prior studies found later age of acquisition (AoA) of a second language in association with more diffuse, non-traditional language representation. While such findings have clear clinical implications, little research has examined relationships among linguistic history, neuroanatomical integrity, and language skills in a clinical population. This study examined relationships between subcortical lesions and confrontation naming in strong bilinguals who acquired English (L2) later in life compared to those with earlier AoA.
Participants and Method
Forty-two bilinguals with Spanish as a first language (English L2) were selected from a database of veterans referred for clinical neuropsychological evaluation (M Age = 64 years; M Education = 12 years; 93% men). They reported strong bilingualism after L2 acquisition (M AoA = 10 years), with current English preference. Twenty-nine had neuroimaging, which was coded on a 4-point ordinal scale for lesion burden in white matter and striatum. Moderation models were tested for interaction between AoA and subcortical lesions in bilinguals using different L2 naming outcomes, controlling for age, education, occupation, and English fluency (i.e., Test of Premorbid Functioning).
Results
Moderation showed significant interaction of AoA with striatal lesion burden for scores on all naming tests, with a similar but less robust relationship between white matter lesions and naming outcomes. Graphical analysis revealed subcortical lesions had a negative impact on naming scores in those with later L2 AoA.
Conclusions
Results suggest “atypical” subcortical involvement in naming is more likely for bilinguals who acquired L2 later. While clinicians typically associate impaired naming with temporal lobe dysfunction, findings suggest subcortical dysfunction should be considered among bilinguals with later L2 AoA.

Abstract
Abstract
Objective
To examine Montreal Cognitive Assessment (MoCA) performance and frequency of low scores among veterans with primary diagnoses of cognitive disorder, psychiatric disorder, or no disorder.
Method
A clinic-referred sample of veterans (n = 214; Mage = 66.1, SD = 15; Medu = 13.3, SD = 2.7) diagnosed with mild cognitive impairment (MCI; n = 97), dementia (n = 47), depression (n = 18), PTSD (n = 22), or no cognitive or psychiatric disorder (n = 30) were included. All participants were administered the MoCA as part of a larger battery of tests. Analysis of covariance (ANCOVA), controlling for age and education, was conducted (Bonferroni correction applied) to compare diagnostic groups on MoCA uncorrected total score.
Results
Across groups, mean MoCA scores were significantly different using ANCOVA, F(4, 207) = 31.5, p < .001. As expected, those with no diagnosis (M = 24.7, SD = 2.1) or psychiatric disorders (PTSD M = 24.4, SD = 4.1; Depression M = 23.9, SD = 3) scored higher than those with cognitive disorder (MCI M = 21.7, SD = 3.1; Dementia M = 17.4, SD = 4.1), p < .001. While both psychiatric groups scored higher than those with dementia (p < .001), the depression group did not significantly differ from those with MCI (p = .11). Examination of scores across all groups revealed a majority of participants scored below the recommended cutoff of < 26. Specifically, 100% of dementia cases, 89.7% of MCI cases, 63.3% of no diagnosis cases, 50% of PTSD cases, and 72.2% of depression cases scored < 26.
Conclusion
Abnormal MoCA scores are common, even in the absence of cognitive impairment. Individuals with PTSD or depression are likely to score below the publisher's recommend cutoff. While this may reflect cognitive symptoms of psychiatric conditions, it may also reflect normative limitations as identified in past studies.

Abstract
Abstract In 2014, the International Endohernia Society (IEHS) published the first international “Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias.” Guidelines reflect the currently best available evidence in diagnostics and therapy and give recommendations to help surgeons to standardize their techniques and to improve their results. However, science is a dynamic field which is continuously developing. Therefore, guidelines require regular updates to keep pace with the evolving literature. Methods For the development of the original guidelines, all relevant literature published up to year 2012 was analyzed using the ranking of the Oxford Centre for Evidence-Based Medicine. For the present update, all of the previous authors were asked to evaluate the literature published during the recent years from 2012 to 2017 and revise their statements and recommendations given in the initial guidelines accordingly. In two Consensus Conferences (October 2017 Beijing, March 2018 Cologne), the updates were presented, discussed, and confirmed. To avoid redundancy, only new statements or recommendations are included in this paper. Therefore, for full understanding both of the guidelines, the original and the current, must be read. In addition, the new developments in repair of abdominal wall hernias like surgical techniques within the abdominal wall, release operations (transversus muscle release, component separation), Botox application, and robot-assisted repair methods were included. Results Due to an increase of the number of patients and further development of surgical techniques, repair of primary and secondary abdominal wall hernias attracts increasing interests of many surgeons. Whereas up to three decades ago hernia-related publications did not exceed 20 per year, currently this number is about 10-fold higher. Recent years are characterized by the advent of new techniques—minimal invasive techniques using robotics and laparoscopy, totally extraperitoneal repairs, novel myofascial release techniques for optimal closure of large defects, and Botox for relaxing the abdominal wall. Furthermore, a concomitant rectus diastasis was recognized as a significant risk factor for recurrence. Despite insufficient evidence with respect to these new techniques, it seemed to us necessary to include them in the update to stimulate surgeons to do research in these fields. Conclusion Guidelines are recommendations based on best available evidence intended to help the surgeon to improve the quality of his daily work. However, science is a continuously evolving process, and as such guidelines should be updated about every 3 years. For a comprehensive reference, however, it is suggested to read both the initial guidelines published in 2014 together with the update. Moreover, the presented update includes also techniques which were not known 3 years before.

Abstract
The targets of the Structural GenomiX (SGX) bacterial genomics project were proteins conserved in multiple prokaryotic organisms with no obvious sequence homolog in the Protein Data Bank of known structures. The outcome of this work was 80 structures, covering 60 unique sequences and 49 different genes. Experimental phase determination from proteins incorporating Se-Met was carried out for 45 structures with most of the remainder solved by molecular replacement using members of the experimentally phased set as search models. An automated tool was developed to deposit these structures in the Protein Data Bank, along with the associated X-ray diffraction data (including refined experimental phases) and experimentally confirmed sequences. BLAST comparisons of the SGX structures with structures that had appeared in the Protein Data Bank over the intervening 3.5 years since the SGX target list had been compiled identified homologs for 49 of the 60 unique sequences represented by the SGX structures. This result indicates that, for bacterial structures that are relatively easy to express, purify, and crystallize, the structural coverage of gene space is proceeding rapidly. More distant sequence-structure relationships between the SGX and PDB structures were investigated using PDB-BLAST and Combinatorial Extension (CE). Only one structure, SufD, has a truly unique topology compared to all folds in the PDB.

Abstract
AIMS To investigate the costs and potential benefits of different policies for antenatal screening for haemoglobinopathies in two multiethnic London communities. METHODS 1000 consecutive antenatal patient samples referred to each of two London teaching hospital laboratories for haemoglobinopathy testing were investigated using the standard procedures of the laboratory in question. When the standard procedures did not include high performance liquid chromatography (HPLC), this technique was added, in order to assess its diagnostic value and cost-effectiveness. A comparison was made between the costs and potential benefits of universal testing for variant haemoglobins and beta thalassaemia trait using HPLC and the costs and potential benefits of universal testing for variant haemoglobins and selective testing for beta thalassaemia trait using the mean cell haemoglobin (MCH) as a screening test and less automated techniques than HPLC for definitive diagnosis. RESULTS The costs of the two policies were found to be comparable, as the higher reagent/instrument costs of HPLC were offset by the lower labour costs. Universal testing of 2000 consecutive samples did not disclose any extra cases of beta thalassaemia trait which would not have been detected by universal screening and selective testing. However, six patients were found to have a haemoglobin A2 variant which can interfere with the diagnosis of beta thalassaemia trait. CONCLUSIONS The introduction of universal testing by HPLC into British laboratories could be cost neutral and has potential benefits. If a higher cost is accepted then the greater degree of automation could be used to release skilled staff for other tasks within the laboratory.

Abstract
The cell surface antigenic phenotype of 18 cases of central nervous system (CNS) large-cell lymphoma (14 primary, four secondary) was examined by an immunoperoxidase technique using antibodies that identify B cell restricted and associated antigens. All cases were shown to be of B cell origin by virtue of the expression of monotypic immunoglobulin (Ig) (16 IgM, two IgG) and the pan B cell antigen B1 (CD20). A panel of monoclonal antibodies directed against B cell restricted and associated activation antigens including B5, Blast-1, Blast-2 (CD23), BB1, interleukin 2 receptor (IL2R, CD25), T9 (transferrin receptor) and TNK-TAR (4F2) was used on 12 of the cases. The majority expressed T9 and TNK-TAR. Blast-1 was expressed by less than half the cases and Blast-2 and B5 by one of 12 cases each. This is in contrast to 10 non-CNS diffuse large cell lymphomas where B5 and Blast-1 were present on all cases. This study confirms previous observations that primary CNS large cell lymphomas are of B cell derivation. Moreover, the differences in expression of B cell activation antigens on CNS large cell lymphomas as compared to non-CNS lymphomas raise the possibility that a subset of neoplastic B cells may have unique tropism for the CNS.

Abstract
In a thymoma, with lymphocytic predominance, we characterized the lymphocytes using a battery of monoclonal antibodies. The T lymphocytes had a phenotype most characteristic of cortical thymocytes (T3+, T4+, T6+, T8+, T11+, TdT+, PNA+).
