Abstract
Bacterial RNP bodies (BR-bodies) are non-membrane-bound structures that facilitate mRNA decay by concentrating mRNA substrates with RNase E and the associated RNA degradosome machinery. However, the full complement of proteins enriched in BR-bodies has not been defined. Here we define the protein components of BR-bodies through enrichment of the bodies followed by mass spectrometry-based proteomic analysis. We found 111 BR-body enriched proteins, including several RNA binding proteins, many of which are also recruited directly to in vitro reconstituted RNase E droplets, showing BR-bodies are more complex than previously assumed. While most BR-body enriched proteins that were tested cannot phase separate, we identified five that undergo RNA-dependent phase separation in vitro, showing other RNP condensates interface with BR-bodies. RNA degradosome protein clients are recruited more strongly to RNase E droplets than droplets of other RNP condensates, implying that client specificity is largely achieved through direct protein-protein interactions. We observe that some RNP condensates assemble with preferred directionally, suggesting that RNA may be trafficked through RNP condensates in an ordered manner to facilitate mRNA processing/decay, and that some BR-body associated proteins have the capacity to dissolve the condensate. Finally, we find that RNA dramatically stimulates the rate of RNase E phase separation in vitro, explaining the dissolution of BR-bodies after cellular mRNA depletion observed previously. Altogether, these results suggest that a complex network of protein-protein and protein-RNA interactions controls BR-body phase separation and RNA processing.

Abstract
Embryonic development is a complex process involving the co-ordinated onset and integration of multiple morphological features and physiological functions. While the molecular basis of morphological development in embryos is relatively well known for traditional model species, the molecular underpinning of the development of physiological functions is not. Here, we used global gene expression profiling to investigate the transcriptional changes associated with the development of morphological and physiological function in the amphipod crustacean Gammarus chevreuxi. We compared the transcriptomes at three timepoints during the latter half of development, characterised by different stages of the development of heart form and function: 10 days post fertilisation (dpf, Early: no heart structure visible), 15 dpf (Middle: heart present but not fully functional), and 18 dpf (Late: regular heartbeat). Gene expression profiles differed markedly between developmental stages, likely representing a change in the activity of different processes throughout the latter period of G. chevreuxi embryonic development. Differentially expressed genes belonged to one of three distinct clusters based on their expression patterns across development. One of these clusters, which included key genes relating to cardiac contractile machinery and calcium handling, displayed a pattern of sequential up-regulation throughout the developmental period studied. Further analyses of these transcripts could reveal genes that may influence the onset of a regular heartbeat. We also identified morphological and physiological processes that may occur alongside heart development, such as development of digestive caeca and the cuticle. Elucidating the mechanisms underpinning morphological and physiological development of non-model organisms will support improved understanding of conserved mechanisms, addressing the current phylogenetic gap between relatively well known model species.

Abstract
BACKGROUND This study explores live and recorded music listening in the outpatient pain clinic. There is evidence demonstrating the effectiveness of live and recorded music in a hospital setting but a comparison study of this kind has yet to be conducted. METHODS A multimethod survey study design was used. A questionnaire utilizing rating scales was self-administered across two outpatient pain clinic waiting rooms. Patients were included through convenience sampling. In one clinic, a playlist of recorded music curated by two of the authors was provided. In the second clinic, a music therapy student played live music using guitar, flute, and voice. The questionnaire gathered data on music's impact on pain and emotional states, as well as attitudes toward music in the waiting room. Quantitative data was analyzed using descriptive statistics and qualitative data, gathered in the questionnaires open ended question, was analyzed using thematic analysis. RESULTS The questionnaire was completed by 200 adult patients. Patients reported lowered levels of anxiety, stress, and pain in both clinics, as well as a shorter waiting time and more caring experience. Patients in the live music clinic reported that music lowered levels of stress, nervousness, agitation, and pain more than in the recorded music clinic. CONCLUSIONS Participants in this study identified that music is a useful tool in the pain clinic waiting room. This study contributes to evidence that music should be considered as a complimentary treatment for people living with pain and in the wider hospital setting. Additional research is warranted with a control group, pre- and posttesting, and studies of music in hospitals in a range of cultural contexts.

Abstract
Introduction While the global dissemination of vaccines targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a decline in the incidence of infections, the case fatality rates have remained relative stable. A major objective of managing hospitalized patients with documented or suspected COVID-19 infection is the rapid identification of features associated with severe illness using readily available laboratory tests and clinical tools. The sequential organ failure assessment (SOFA) score is a validated tool to facilitate the identification of patients at risk of dying from sepsis. Purpose The aim of this study was to assess the discriminatory accuracy of the SOFA score in predicting clinical decompensation in patients hospitalized with COVID-19 infection. Methods We conducted a retrospective analysis at a three-hospital health system, comprised of one tertiary and two community hospitals, located in the Chicago metropolitan area. All patients had positive SARS-CoV-2 testing and were hospitalized for COVID-19 infection. The primary outcome was clinical decompensation, defined as the composite endpoint of death, ICU admission, or need for intubation. We utilized the most abnormal laboratory values observed during the admission to calculate the SOFA score. Receiver Operating Curves (ROC) were then constructed to determine the sensitivity and specificity of SOFA scores. Results Between March 1st and May 31st 2020, 1029 patients were included in our analysis with 367 patients meeting the study endpoint. The median SOFA score was 2.0 IQR (Q1, Q3 1,4) for the entire cohort. Patients who had in-hospital mortality had a median SOFA score of 4.0 (Q1,Q3 3,7). In patients that met the primary composite endpoint, the median SOFA score was 3.0, IQR (Q1, Q3 2,6). The ROC was 0.776 (95% CI 0.746–0.806, p<0.01). Conclusion The SOFA score demonstrates strong discriminatory accuracy for prediction of clinical decompensation in patients presenting with COVID-19 at our urban hospital system.

Abstract
Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a pandemic which has infected more than 128 million people and led to over 2.8 million deaths worldwide. Although the introduction of efficacious vaccines has led to overall declines in the incidence of SARS-CoV-2 infection, there has been a recent increase in infections once more due to the appearance of mutant strains with higher virulence. It therefore remains vital to identify predictors of poor outcomes in this patient population. Purpose The objective of our study was to identify predictors of prolonged hospitalization, intensive care unit (ICU) admission, intubation, and death in patients infected with SARS-CoV-2. Methods We conducted a retrospective analysis of all patients hospitalized with SARS-CoV-2 at our health system that includes one tertiary care center and two community hospitals located in the Chicago metropolitan area. The main outcome was a composite endpoint of hospitalization >28 days, ICU admission, intubation, and death. Explanatory variables associated with the primary outcome in the bivariate analysis (p<0.05) were included in the multivariable logistic regression model. Statistical analysis was performed using IBM SPSS 25.0. Results Between March 1, 2020 and May 31, 2020, 1029 patients hospitalized with SARS-CoV-2 were included in our analysis. Of these patients, 379 met the composite endpoint. Baseline demographics are described in Table 1. Of note, our cohort consisted of a predominantly minority patient population including 47% Hispanic, 17% African American, 16% Caucasian, and 16% other. In bivariate analysis, age, hypertension, tobacco and alcohol abuse, obesity, coronary artery disease, arrhythmias, valvular heart disease, dyslipidemia, hypertension, stroke, diabetes, documented thrombosis, troponin, CRP, ESR, ferritin, LDH, BNP, D-dimer >5x the upper limit of normal, lactate, and right ventricular outflow tract velocity time integral <9.5 were significant. After multivariable adjustment, explanatory variables associated with the composite endpoint included troponin (OR 2.36; 95% CI 1.08–5.17, p 0.03), D-dimer (OR 1.5; 95% CI 1.23–1.98, p<0.01, lactate (OR 1.58; 95% CI 1.28–1.95, p<0.01), and documented thrombosis (OR 3.56; 95% CI 1.30–8.70, p<.05). Race was not a predictor of poor outcomes in the bivariate or multivariate analysis (Table 2). Conclusions In a large urban cohort with a predominantly minority population, we identified several clinical predictors of poor outcomes. Of note, race was not a predictor of the primary endpoint in this study. While recent literature has demonstrated worse outcomes among racial minorities infected with SARS-CoV-2, our data suggests these variations are related to social determinants of health rather than biologic causes.

Abstract
Introduction Video consultation involves the live interaction between the doctor and the patient remotely. Prior to the Covid-19 pandemic, the majority of video consultations in primary care were provided by GPs who were not the individual's own GP, which presented safety and continuity issues. This study aims to determine GPs' attitudes to the use of video consultation for their own patients. Methods This was a qualitative study involving semi-structured interviews. Participants were purposively recruited through use of a GP tutor as a key informant and guided by a sampling framework to include those with and without previous video consultation experience. Braun and Clarke thematic analysis was used. Results Participants included eight GPs, half of whom had previously worked with video consultation. Four themes emerged: impact on the consultation, the potential role, and the potential threat to current practice and technology and logistics. There were optimistic and cautious observations within all themes. Conclusion With the increased use of video consultation, Irish General Practice is in a unique position to frame the future its use. The provision of this modality to one's own patients may provide benefit while mitigating some of the pitfalls but would not entirely avoid the potential dangers of video consultation.

Abstract
Motility regulation plays a key role in prokaryotic responses to environmental stimuli. Here, we used a motility screen and selection to isolate hypermotile Haloferax volcanii mutants from a transposon insertion library. Whole genome sequencing revealed that hypermotile mutants were predominantly affected in two genes that encode HVO_1357 and HVO_2248. Alterations of these genes comprised not only transposon insertions but also secondary genome alterations. HVO_1357 contains a domain that was previously identified in the regulation of bacteriorhodopsin transcription, as well as other domains frequently found in two-component regulatory systems. The genes adjacent to hvo_1357 encode a sensor box histidine kinase and a response regulator, key players of a two-component regulatory system. None of the homologues of HVO_2248 have been characterized, nor does it contain any of the assigned InterPro domains. However, in a significant number of Haloferax species, the adjacent gene codes for a chemotaxis receptor/transducer. Our results provide a foundation for characterizing the root causes underlying Hfx. volcanii hypermotility.

Abstract
The neurofibromatoses [NF 1, NF 2 and schwannomatosis] are a group of genetic disorders that lead to the development of nervous system tumours and have diverse dermatologic, neurologic, ophthalmic, skeletal and vascular effects. The most common is NF 1 (Neurofibromatosis 1) also known as von Recklinghausen's disease, which is one of the most common human genetic diseases. Oral manifestations of NF 1 are reported in 72% of cases and in one of our cases precipitated attendance at a general dental practitioner (GDP), subsequent diagnosis and genetic screening for family members. This disease may go undiagnosed due to its variable expressivity of symptoms. The pivotal importance of a GDP in the discovery and early referral to an oral or oral and maxillofacial surgeon for further investigation and diagnosis of this condition is highlighted. Knowledge of the most common features of neurofibromatosis can facilitate the speedy referral and subsequent diagnosis of generalized neurofibromatosis, local surgical management of benign neoplasms and long term management of its other clinical features. Dentists should be aware of the classic symptoms of this condition and of their role in long-term care in view of the risk of local recurrence and malignant transformation.

Abstract
Abstract
Background
Integration of complementary therapies alongside conventional medical treatment is common and affects health behaviour and outcomes. Nurses frequently interact with patients and their attitudes to these therapies may play a significant role in decision-making. This mixed-method study investigated nurses' attitudes and behaviour towards complementary therapies.
Methods
A sequential exploratory design was utilised. Qualitative data were collected via interviews with nurses working in primary and tertiary settings, in all states of Australia. Interview data underwent thematic analysis. Findings from the interviews informed the development of a questionnaire, which was used to conduct a national online survey. Survey data were descriptively analysed using frequency distributions and percentages.
Results
Nineteen nurses were interviewed and 614 responded to the survey. Themes that emerged from the qualitative data were; Promoting safe care, Seeking complementary therapies knowledge; Supporting holistic health care and Integrating complementary therapies in practice. Survey responses revealed most nurses (77.5%) discussed complementary therapies with patients. More than one half (55.5%) would 'sometimes' recommend complementary therapies and 12.0% would 'almost always/always' do so. The majority (91.8%) believed nurses should have some understanding of complementary therapies. There was a lack of agreement regarding integration of these therapies into nursing practice.
Conclusions
Nurses were generally supportive of patients' interest in complementary therapies and want basic education about these therapies.
Key messages
Nurses working in Australia often engage with patients about complementary therapies. Increasing nurses’ complementary therapy knowledge is likely to promote informed decision-making and improve patient safety.

Abstract
Community initiatives aiming to reduce health inequalities are increasingly common in health policy. Though diverse many such initiatives aim to support residents of disadvantaged places to exercise greater collective control over decisions/actions that affect their lives - which research suggests is an important determinant of health - and some seek to achieve this by giving residents control over a budget. Informed by theoretical work in which community capabilities for collective control are conceptualised as different forms of power, and applying a relational lens, this paper presents findings on the potential role of money as a mechanism to enhance these capabilities from an on-going evaluation of a major place-based initiative being implemented in 150 neighbourhoods across England:The Big Local (BL). The research involved semi-structured interviews with 116 diverse stakeholders, including residents and participant observation in a diverse sample of 10 BL areas. We took a thematic constant comparative approach to the analysis of data from across the sites. The findings suggest that the money enabled the development of capabilities for collective control in these communities primarily by enhancing connectivity amongst residents and with external stakeholders. However, residents had to engage in significant 'relational work' to achieve these benefits and tensions around the money could hinder communities' 'power to act'. Greater social connectivity has been shown to directly affect individual and population health by increasing social cohesion and reducing loneliness. Additionally, supporting enhanced collective control of residents in these disadvantaged communities has the potential to improve population health and reduce health inequalities.

Abstract
This article reports on the responses of 120 teachers and habilitative specialists of multiply handicapped blind and deaf-blind children in Massachusetts to a survey on their use of assistive technology. The respondents reported problems in all areas covered by the survey: knowledge of electronic mobility aids and communication devices; the availability, maintenance, and funding of devices; and adequate information about devices. They especially mentioned the need for resources to assess and match students to appropriate devices and to generate more training for themselves.

Abstract
Background Informed consent is an integral part of clinical practice. There is widespread agreement amongst health professionals that obtaining procedural consent needs to move away from a unidirectional transfer of information to a process of supporting patients in making informed, self‐determined decisions. This review aimed to identify processes and measures that warrant consideration when engaging in consent‐based discussions with competent patients undergoing elective procedures. Methods Formal written guidance from the General Medical Council and Royal College of Surgeons of England, in addition to peer‐reviewed literature and case law, was considered in the formulation of this review. Results A framework for obtaining consent is presented that is informed by the key tenets of shared decision‐making (SDM), a model that advocates the contribution of both the clinician and patient to the decision‐making process through emphasis on patient participation, analysis of empirical evidence, and effective information exchange. Moreover, areas of contention are highlighted in which further guidance and research are necessary for improved enhancement of the consent process. Conclusion This SDM‐centric framework provides structure, detail and suggestions for achieving meaningful consent.

Abstract
Background:Articular manifestations are the most frequent extra-digestive manifestations of Inflammatory Bowel Disease (IBD). Anti-TNF have proved to be as effective on articular symptoms as on IBD’s ones, but have been suspected to induce paradoxical articular manifestations.Objectives:The aims of this study were to describe the frequency, the type and the management of all articular manifestations occurring in patients treated with anti-TNF for IBD and to look for factors associated with their occurrence.Methods:In this retrospective monocentric study, we included all patients who received an anti-TNF for an IBD in our tertiary hospital referent for inflammatory rheumatic and bowel diseases. We searched for all incident articular manifestations occurring during treatment with anti-TNF, including new or recurrent articular manifestations. Characteristics of patients with paradoxical articular manifestations (defined as inflammatory articular symptoms occurring while IBD was in remission, without immunization against anti-TNF) were compared to that of patients without articular manifestations to identify factors associated with their occurrence.Results:Through a systematic search of all IBD patients seen in our tertiary hospital between February 2013 and May 2017, we identified 442 patients (36.2±15 years, 50.5% men) who had ever received an anti-TNF for IBD: Crohn’s disease (n=277), ulcerative colitis (154) and undetermined colitis (n=11). 74 (16.7%) had already a history of inflammatory articular manifestations including 37 patients with a diagnosis of spondyloarthritis (SpA) made before anti-TNF’s beginning.Among them, 115 (26%) patients developed a new articular manifestation after a mean of 20 (±22) months of treatment: mechanical in 56 (12.6%) and inflammatory in 59 (13.3%). Within patients with new inflammatory articular manifestations: 39% were paradoxical, 27% were concomitant of an IBD flare, 27% were associated to an immunization against anti-TNF, 3% were induced lupus, 2% were chondrocalcinosis and 2% were polymyalgia rheumatic. Articular manifestations associated to an immunization were linked to a loss of efficiency of the treatment for 62%, with (42%) or without (20%) associated digestive symptoms and 38% were due to delayed hypersensitivity reaction. Among paradoxical articular manifestations, 83% were new articular symptoms, including 35% of SpA de novo, and 17% were recurrence of known articular manifestations. The only predictive factor of paradoxical articular manifestation was a previous diagnosis of SpA (21.7% vs 6.8%; p=0.02). Paradoxical manifestations improved in 17 patients despite continuation of anti-TNF, methotrexate was added in 2 and anti-TNF was discontinued in only 4 patients.Conclusion:Inflammatory articular manifestations occurred in about 13% of patients treated with anti-TNF for IBD. More than a quarter were linked to an immunization against anti-TNF, which has to be searched in this situation. Less than half of them (39%) were paradoxical. In most of cases, they were transitory and did not require anti-TNF’s discontinuation. The only predictive factor of paradoxical articular manifestations was having a history of SpA.References:[1]Thiebault H, et al.

Abstract
Abstract
Introduction
Sleep problems are highly prevalent in early childhood but often under-identified in pediatric primary care. This study identified the prevalence of caregiver-reported versus primary care provider (PCP)-documented sleep problems and sleep-related health behaviors in young children presenting to well child visits (WCVs).
Methods
Caregivers (85.4% mothers) of 198 young children (2-5 years, M = 3.3, 53.7% female, 62.9% Black) presenting to urban (74.1%) and suburban (25.9%) primary care sites for well child visits (WCVs) completed research surveys on child behavioral sleep problems, snoring, and sleep-related health behaviors (e.g., caffeine consumption) on the day of their child’s WCV. Electronic medical record review was used to identify the rate of PCP-documented sleep problems and related recommendations in the WCV progress note.
Results
Fifteen percent of caregivers reported a child sleep problem according to questionnaire data, which did not significantly differ from the 12.0% of children with a PCP-documented sleep problem in the WCV progress note (p = .31). However, significantly more caregivers (28.3%) reported bedtime difficulties (resistance; tantrums) on questionnaires (p <.001), which were not captured in the 12.0% of WCVs noting sleep problems. A total of 8% of WCVs included child sleep recommendations. Child snoring was reported by 17.0% of caregivers, but was less frequently documented in WCVs (4.5%, p <.001). Although many caregivers reported poor child sleep-related health behaviors, including daily child caffeine consumption (21.1%) and bedroom electronics (62.9%), significantly fewer PCPs documented these issues (caffeine: 2.0%; electronics: 6.6%) or related recommendations (decrease caffeine: 1.0%; eliminate electronics: 3.5%) in the progress note (all p-values <.001).
Conclusion
Although caregiver-endorsed child sleep problems on surveys did not differ from PCP-documented concerns, there are gaps in documenting other problematic sleep-related health behaviors, such as caffeine consumption and electronics use. More resources to address sleep-related health behaviors, as well as sleep problems, in pediatric primary care are needed.

Abstract
Abstract
Introduction
The aim of this study was to assess parent perceptions of sleep problems in young children and parent-identified areas of change in a global sample.
Methods
Caregivers (95.6% mothers) of 1555 infants/toddlers (birth-37 mos; M=12.2 mos; 49.5% male) completed an online survey, representing Indonesia (n=187), Japan (n=718), New Zealand (n=231), Singapore (n=199), and Thailand (n=221). The survey included an abbreviated version of the Brief Infant Sleep Questionnaire, and a list of potential sleep-related areas of change.
Results
36.9% reported a perceived sleep-problem, whereas 92.9% indicated an area of desired change related to their child’s sleep. In terms of areas of change, 82.5% endorsed bedtime/how child falls asleep, 70.0% nighttime sleep, and 57.8% related to the morning. As expected, 99.7% of parents who endorsed a problem indicated a desired change compared to 88.9% who did not perceive a problem, p < .001. Those who noted a problem were more likely to endorse a change at bedtime (92.5%) and during the night (90.1%), compared to the morning (68.8%). There were country-based differences, with caregivers in New Zealand (47.0%) and Singapore (44.2%) more likely to report a child sleep problem compared to Thailand (35.3%), Japan (34.1%) and Indonesia (29.4%), p < .001. No differences were noted in parent-report of desired change across Japan, New Zealand, Singapore, and Thailand (94-96%) but were significantly higher than Indonesia (83.4%).
Conclusion
Although one-third of parents of young children in a global sample indicate a perceived sleep problem, almost all parents wish to change something about their child’s sleep, primarily relate to bedtime and during the night. Sleep education and assessment delivered by health care providers should focus not only on what families consider to be “problematic,” but also what families would like to modify, or improve, about their child’s sleep within a developmentally appropriate framework.

Abstract
Background Physical fitness is impaired after stroke, yet fitness training after stroke reduces disability. Several international guidelines recommend that fitness training be incorporated as part of stroke rehabilitation. However, information about cost-effectiveness is limited. Methods A decision tree model was used to estimate the cost-effectiveness of a fitness programme for stroke survivors vs. relaxation (control group). This was based on a published randomised controlled trial, from which evidence about quality of life was used to estimate Quality Adjusted Life Years. Costs were based on the cost of the provision of group fitness classes within local community centres and a cost per Quality Adjusted Life Year was calculated. Results The results of the base case analysis found an incremental cost per Quality Adjusted Life Year of £2,343. Conclusions Physical fitness sessions after stroke are a cost-effective intervention for stroke survivors. This information will help make the case for the development of new services.

Abstract
There has been a recent shift in global perception of plastics in the environment, resulting in a call for greater action. Science and the popular media have highlighted plastic as an increasing stressor [1,2]. Efforts have been made to confer protected status to some remote locations, forming some of the world's largest Marine Protected Areas, including several UK overseas territories. We assessed plastic at these remote Atlantic Marine Protected Areas, surveying the shore, sea surface, water column and seabed, and found drastic changes from 2013-2018. Working from the RRS James Clark Ross at Ascension, St. Helena, Tristan da Cunha, Gough and the Falkland Islands (Figure 1A), we showed that marine debris on beaches has increased more than 10 fold in the past decade. Sea surface plastics have also increased, with in-water plastics occurring at densities of 0.1 items m-3; plastics on seabeds were observed at ≤ 0.01 items m-2. For the first time, beach densities of plastics at remote South Atlantic sites approached those at industrialised North Atlantic sites. This increase even occurs hundreds of meters down on seamounts. We also investigated plastic incidence in 2,243 animals (comprising 26 species) across remote South Atlantic oceanic food webs, ranging from plankton to seabirds. We found that plastics had been ingested by primary consumers (zooplankton) to top predators (seabirds) at high rates. These findings suggest that MPA status will not mitigate the threat of plastic proliferation to this rich, unique and threatened biodiversity.

Abstract
The non-isothermal drying behavior and kinetics of human feces (HF) were investigated by means of thermogravimetric analysis to provide data for designing a drying unit operation. The effect of heating rate and blending with woody biomass were also evaluated on drying pattern and kinetics. At low heating rate (1 K/min), there is effective transport of moisture, but a higher heating rate would be necessary at low moisture levels to reduce drying time. Blending with wood biomass improves drying characteristics of HF. The results presented in this study are relevant for designing non-sewered sanitary systems with in-situ thermal treatment.

Abstract
Abstract
Purpose
This study sought to investigate whether concussion in older adults improves through evaluating their performance on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) and Vestibular/Ocular-Motor Screen (VOMS) across visits and to describe and better characterize concussion in this at-risk population.
Methods
We conducted a retrospective review of medical records for 69 older adult patients (40 females, 29 males) that presented to a concussion specialty clinic. Participants averaged 64.71 (SD=4.1) years in age and presented within 6-998 days of injury (SD=170.9). Demographics and clinical data were recorded at intake through last appointment. Descriptive analysis, including frequencies, means, and standard deviations were performed as well as paired T-test to compare mean scores for first and last visit. Statistical significance was determined by two-sided p-values <.05.
Results
Twenty out of 69 participants (29%) reported a previous concussion. Concussion symptom severity scores at participants’ first clinic visit averaged 56.19 (SD=26.56) compare with 39.51 (SD=25.53) at their final clinic visit. When comparing ImPACT data, all scores improved comparatively from Visit 1 to Last Visit (P values =0.000-0.014); all VOMS total scores improved as well (P =0.00-0.047). The most frequent primary profile among participants was Vestibular (31.9%).
Conclusion
Older adults diagnosed with concussion showed improvement on ImPACT scores and their symptom severity scores decreased. The most frequent primary concussion profile at initial visit was Vestibular. Further research with this at-risk population is needed.

Abstract
Abstract
Purpose
The objective of this study was to examine differences in self-reported symptoms, neurocognitive performance, and vestibular-ocular insufficiencies between patients’ first and second concussions. A secondary purpose was to explore the role of risk factors on recovery.
Methods
We conducted a retrospective medical chart review of 73 (32-M/41-F) patients aged 15.69 (SD=1.67) years from a concussion specialty clinic with two separate concussions (84.9% of 1st and 79.5% of 2nd sport-related) that occurred between August 2010 and April 2018. Clinical outcomes included the PCSS, ImPACT, and the Vestibular/Ocular Motor Screening (VOMS). A series of paired samples t-tests were used to compare clinical outcomes along with chi-square analyses for risk factor associations.
Results
Verbal memory scores were higher following the second (M=80.67, SD=15.3) (M=76.32, SD=15.65) (t[73]=–2.18, p=.03) concussion. Visual motor processing speed was faster following the second concussion (M=35.04, SD= 7.90) (M=31.35, SD=7.63) (t[73]=–5.72, p<.001). There were no other significant differences observed. Recovery time was similar for the first (61.07, SD=58.41.5) and second (67.91 SD=70.10) respectively, t(70)=–.91, p=.37. There was no relationship between any risk factors, and recovery time for either injury with the exception a significant association between gender and recovery time (>21 days) with the 1st injury for females (χ2, N=73)=10.58, p=.001.
Conclusion
Findings suggest that a second concussion does not result in more pronounced symptoms, worse neurocognitive performance, or increased deficits on vestibular/ocular performance and/or longer recovery time. The only significant risk factor to a recovery over 21 days included gender.

Abstract
Abstract
Purpose
To examine the reliability of near point of convergence (NPC) across three trials and determine if one trial of NPC is adequate to identify receded NPC post-concussion.
Methods
Participants included 263 concussed patients (64.3% male; age=16.92±3.49 years) evaluated within 21 days of injury. NPC was measured in centimeters from the tip of the nose using a fixation stick and a Gulick anthropometric tape measure. A two-way, mixed effect, absolute agreement intraclass correlation coefficient (ICC 3,1) was conducted to evaluate reliability across the three trials. A chi-square analysis examined consistency of NPC classification (normal/abnormal) on the initial trial compared to average across three trials.
Results
Reliability of the three trials was high (.91 [95%CI, .89–.93]). Agreement between Trial 1 classification and classification based on average of all three trials was high (96.2%). Of the 10 participants who were classified differently for Trial 1 compared to average trials, 8 had borderline (e.g., 4–6 cm) measurements on the first trial.
Conclusion
NPC measurement across trials is reliable for the overall sample, but those who fell well below (i.e. 0–1cm) or well above (>8cm) clinical cutoffs on the first trial were almost always below or above respective cutoffs on the average convergence (>99%). Results suggest it is important to measure NPC across multiple trials for patients with initial borderline measurement.

Abstract
The "Reinvent the Toilet Challenge" set by the Bill & Melinda Gates Foundation aims to bring access to adequate sanitary systems to billions of people. In response to this challenge, on-site sanitation systems are proposed and being developed globally. These systems require in-situ thermal treatment, processes that are not well understood for human faeces (HF). Thermogravimetric analysis has been used to investigate the pyrolysis, gasification and combustion of HF. The results are compared to the thermal behaviour of simulant faeces (SF) and woody biomass (WB), along with the blends of HF and WB. Kinetic analysis was conducted using non-isothermal kinetics model-free methods, and the thermogravimetric data obtained for the combustion of HF, SS and WB. The results show that the devolatilisation of HF requires higher temperatures and rates are slower those of WB. Minimum temperatures of 475 K are required for fuel ignition. HF and SF showed similar thermal behaviour under pyrolysis, but not under combustion conditions. The activation energy for HF is 157.4 kJ/mol, relatively higher than SS and WB. Reaction order for HF is lower (n = 0.4) to WB (n = 0.6). In-situ treatment of HF in on-site sanitary systems can be designed for slow progressive burn.

Abstract
Hyperphosphatemic familial tumoral calcinosis (HFTC), secondary to fibroblast growth factor 23 (FGF23) gene mutation, is a rare genetic disorder characterized by recurrent calcified masses. We describe young Lebanese cousins presenting with HFTC, based on a retrospective chart review and a prospective case study. In addition, we present a comprehensive review on the topic, based on a literature search conducted in PubMed and Google Scholar, in 2014 and updated in December 2017. While the patients had the same previously reported FGF23 gene mutation (homozygous c.G367T variant in exon 3 leading to a missense mutation), they presented with variable severity and age of disease onset (at 4 years in patient 1 and at 23 years in patient 2). A review of the literature revealed several potential patho-physiologic pathways of HFTC clinical manifestations, some of which may be independent of hyperphosphatemia. Most available treatment options aim at reducing serum phosphate level, by stimulating renal excretion or by inhibiting intestinal absorption. HFTC is a challenging disease. While the available medical treatment has a limited and inconsistent effect on disease symptomatology, surgical resection of calcified masses remains the last resort. Research is needed to determine the safety and efficacy of FGF23 replacement or molecular therapy, targeting the specific genetic aberration. Hyperphosphatemic familial tumoral calcinosis is a rare genetic disorder characterized by recurrent calcified masses, in addition to other visceral, skeletal, and vascular manifestations. It remains a very challenging disease.

Abstract
In this study, membrane distillation is evaluated as a technology for non-sewered sanitation, using waste heat to enable separation of clean water from urine. Whilst membrane fouling was observed for urine, wetting was not evident and product water quality met the proposed discharge standard, despite concentration of the feed. Fouling was reversible using physical cleaning, which is similar to previous membrane studies operating without pressure as the driving force. High COD reduction was achieved following faecal contamination, but mass transfer was impeded and wetting occurred which compromised permeate quality, suggesting upstream intervention is demanded to limit the extent of faecal contamination.

Abstract
Background Ipilimumab, an immune checkpoint inhibitor targeting CTLA-4, prolongs survival in a subset of patients with metastatic melanoma (MM) but can induce immune-related adverse events, including enterocolitis. We hypothesized that baseline gut microbiota could predict ipilimumab anti-tumor response and/or intestinal toxicity. Patients and methods Twenty-six patients with MM treated with ipilimumab were prospectively enrolled. Fecal microbiota composition was assessed using 16S rRNA gene sequencing at baseline and before each ipilimumab infusion. Patients were further clustered based on microbiota patterns. Peripheral blood lymphocytes immunophenotypes were studied in parallel. Results A distinct baseline gut microbiota composition was associated with both clinical response and colitis. Compared with patients whose baseline microbiota was driven by Bacteroides (cluster B, n = 10), patients whose baseline microbiota was enriched with Faecalibacterium genus and other Firmicutes (cluster A, n = 12) had longer progression-free survival (P = 0.0039) and overall survival (P = 0.051). Most of the baseline colitis-associated phylotypes were related to Firmicutes (e.g. relatives of Faecalibacterium prausnitzii and Gemmiger formicilis), whereas no colitis-related phylotypes were assigned to Bacteroidetes. A low proportion of peripheral blood regulatory T cells was associated with cluster A, long-term clinical benefit and colitis. Ipilimumab led to a higher inducible T-cell COStimulator induction on CD4+ T cells and to a higher increase in serum CD25 in patients who belonged to Faecalibacterium-driven cluster A. Conclusion Baseline gut microbiota enriched with Faecalibacterium and other Firmicutes is associated with beneficial clinical response to ipilimumab and more frequent occurrence of ipilimumab-induced colitis.

Thrombus was induced in the inferior vena cava of male Wistar rats using reduced flow (80-90% stenosis). The vessel wall was examined at 1hr by scanning electron microscopy. Resolving thrombi with surrounding vena cava were obtained at 1, 7, 14 and 21 days after induction (n = 8). Sections, taken at 0.5 mm intervals (10-15 sections per thrombus), were stained using haematoxylin, Martius Scarlet Blue and antibodies against monocytes, platelets and fibrin. Sections from human venous thrombi (n = 4) were similarly stained. The area occupied by monocytes (in relative pixel units, RPU) was determined using computer aided image analysis. Peripheral rat blood monocytes were extracted, fluorescently labelled and injected intravenously into 7 rats prior to thrombus induction. Vena cava with thrombus was harvested 1 h, 2, 3, 4, 7, 14 and 25 days after induction and their fluorescence measured. The fluorescent content of the caval wall and thrombus was analysed in greater detail at 2 and 25 days after thrombus induction (n = 4 at each time interval). Results. Experimental thrombi were structurally similar to human thrombus and resolved within 14-21 days. Scanning electron microscopy showed minimal endothelial damage at 1 h with signs of early thrombus formation (platelet, red cell leukocyte and fibrin deposition). Neutrophils were the predominant leukocyte in the thrombus at 1 day, with monocytes making up only 0.3% (0.04% sem) of the area of the thrombus. There was a steady increase in thrombus monocyte content and by 21 days the percentage area of thrombus covered by monocytes had increased by over 35 fold to 11.5% (2.3% sem) (p <0.001). Initially, monocytes appeared around the edge of the thrombus and became more evenly distributed through the thrombus as resolution progressed. Labelled monocytes could be found in the circulation up to 1 week after infusion. The fluorescent content (RPU) of the thrombus increased over 25 days (mean RPU At 2 days 0.012, sem 0.005; mean RPU at 25 days 1.062, sem 0.252, p = 0.008). The number of labelled monocytes in the vessel wall peaked at 2 days and decreased thereafter.

Abstract
SummaryCurrent biochemical markers of thrombosis, such as d-dimer, are of little value in demonstrating the presence of thrombus postoperatively, as their levels are elevated by surgery. Thrombosis involves adhesive interactions between the endothelium, platelets and leukocytes. The aim of the study was to determine which of a panel of haemostatic and adhesion factors are altered by the presence of thrombus, but not by surgery. These factors were measured in 20 patients with established spontaneous DVTs, 13 patients having hip replacement surgery and 28 control patients. Circulating levels of P-selectin, VCAM-1 and tissue factor were found to be increased when thrombus was present (p <0.018, p <0.0001, p <0.0028 respectively), but were not altered by surgery. The significance of these circulating factors in venous thrombosis remains to be established, but it is conceivable that they are the product of increased leukocyte trafficking and activity. Assay of VCAM-1, in particular, may be of use in the early detection of venous thrombi in postoperative patients.

Abstract
BACKGROUND Immune check-point blockade agents have shown clinical activity in cancer patients but are associated with immune-related adverse events that could limit their development. The aim of this study was to describe the gastrointestinal immune-related adverse events (GI-irAE) in patients with cancer treated with anti-PD-1. METHODS this is a retrospective study of consecutive adult patients who had a suspected GI-irAE due to anti-PD-1 antibodies between 2013 and 2016. Patients were recruited through a pharmacovigilance registry. Patients' data were reviewed by a multidisciplinary committee that included gastroenterologists, oncologists and a pathologist. Quantitative variables are described by median (range), qualitative variable by frequency (percentage). RESULTS Forty-four patients were addressed to a Gastroenterology unit for a suspected GI-IrAE. Twenty patients had a confirmed GI-irAE related to anti-PD-1, which occurred 4.2 months (0.2; 22.1) after the initiation of anti-PD-1. GI-IrAE incidence rate under anti-PD-1 treatment was estimated to be 1.5%. Among patients with GI-IrAE, main symptoms were diarrhoea (n = 16, 80%), abdominal pain (n = 13, 65%), nausea and vomiting (n = 11, 55%), intestinal obstruction (n = 1, 5%), and haematochezia (n = 2, 10%). No patient had colectomy. Four distinct categories of GI-irAE were observed: acute colitis (n = 8, 40%), microscopic colitis (n = 7, 35%), upper gastrointestinal tract inflammation (n = 4, 20%) and pseudo-obstruction (n = 1, 5%). Response rates to corticosteroids were 87.5% (7/8) in acute colitis, 57% (4/7) in microscopic colitis and 75% (3/4) in upper gastrointestinal tract inflammation. Median time to resolution was 36 days (6-172) in acute colitis, and 98 days (42-226) in microscopic colitis. CONCLUSION This study suggests that GI-irAE are different and less frequent with anti PD-1 than with anti CTLA-4.

Abstract
Mapping forensic psychiatric services with the security needs of patients is a salient step in service planning, audit and review. A valid and reliable instrument for measuring the security needs of Chinese forensic psychiatric inpatients was not yet available. This study aimed to develop and validate the Chinese version of the Security Needs Assessment Profile for measuring the profiles of security needs of Chinese forensic psychiatric inpatients. The Security Needs Assessment Profile by Davis was translated into Chinese. Its face validity, content validity, construct validity and internal consistency reliability were assessed by measuring the security needs of 98 Chinese forensic psychiatric inpatients. Principal factor analysis for construct validity provided a six-factor security needs model explaining 68.7% of the variance. Based on the Cronbach's alpha coefficient, the internal consistency reliability was rated as acceptable for procedural security (0.73), and fair for both physical security (0.62) and relational security (0.58). A significant sex difference (p=0.002) in total security score was found. The Chinese version of the Security Needs Assessment Profile is a valid and reliable instrument for assessing the security needs of Chinese forensic psychiatric inpatients.
