Abstract
PURPOSE Physical activity (PA) is proposed for long-term problems after traumatic brain injury (TBI) with mood, quality of life, and participation. However, COVID-19 mitigation strategies resulted in widespread closures of community-based fitness centres, including one housing a peer-assisted PA program (TBI-Health). The purpose of this study was to provide an in-depth exploration of COVID-19's impact on the TBI-Health program for adults with moderate-to-severe TBI and determine how their PA behaviours could be supported in the pandemic. METHODS Interpretative phenomenological analysis was employed to collect and analyze data from semi-structured Zoom-facilitated interviews with seven female and nine male adults with moderate-to-severe TBI (including program participants and mentors). RESULTS Three major themes were identified. Need for PA after TBI included specific benefits of PA after TBI and desire for an adapted PA program. Lasting Impacts of the TBI-Health Program identified belonging to the TBI-Health community, benefits, and knowledge transfer from the program. Resilience and Loss through the Pandemic comprised the repercussions of COVID-19, loss of the PA program, adapting PA to the pandemic, and resilience after TBI. CONCLUSION This study provides insights about impacts of participating in community-based peer-assisted PA programs after moderate-to-severe TBI and ways to support PA in unforeseen circumstances.

Abstract
This study explores how providing assisted dying services affects the psychological distress of practitioners. It investigates the influence of professional norms that endorse such services within their field. Study 1 included veterinarians (N = 137, 75.2% female, Mage = 43.1 years, SDage = 12.7 years), and Study 2 health practitioner students (N = 386, 71.0% female, Mage = 21.0 years, SDage = 14.4 years). In both studies, participants indicated their degree of psychological distress following exposure to scenarios depicting assisted dying services that were relevant to their respective situations. In Study 1, we found that higher willingness to perform animal euthanasia was associated with lower distress, as were supportive norms. In Study 2, a negative association between a greater willingness to perform euthanasia and lower psychological distress occurred only when the provision of such services was supported by professional norms. In conclusion, psychological distress is buffered by supportive professional norms.

Abstract
PRIMARY OBJECTIVE To explore the experiences of program mentors, participants, and employees involved in a peer-based physical activity (PA) program for adults with moderate-to-severe TBI, being piloted by a community fitness center, to develop the program as a measurable intervention. RESEARCH DESIGN We adopted an exploratory case study approach through an interpretivist paradigm, which focused on discovering realities about the peer-based PA program across the study participants' views, backgrounds, and experiences. METHODS AND PROCEDURES Semi-structured focus groups and individual interviews were conducted with nine adult program participants (3 peer mentors, 6 participants), and three program employees. Inductive content analysis was used to develop themes about their perceived experiences. MAIN OUTCOMES AND RESULTS 44 open-codes were grouped into 10 subthemes and three final themes: 1) program impacts identified the importance of the program in daily life and resulting psychological, physical, and social outcomes; 2) program characteristics highlighted program leaders, accessibility, and social inclusion; 3) program sustainability included program adherence, benefits for the center, and the program's future. CONCLUSIONS Perceptions of program experiences and outcomes identified how peer-based PA for adults with moderate-to-severe TBI can lead to meaningful activities, functioning better, and buy-in from all parties. Implications for research and practice related to supporting health-related behaviors after TBI through group-based, autonomy-supporting approaches are discussed.

Abstract
BackgroundWork is an important outcome for people with inflammatory arthritis (IA including PsA, RA, AxSpA) and osteoarthritis (OA). It is known that people with IA and OA are at increased risk of sick leave and have to stop working early due to ill health. In addition to being at increased risk of becoming work disabled and increased absenteeism, high levels of presenteeism (i.e. reduced productivity/limited ability to work due to ill health whilst at work) have also been reported. Several instruments exist to measure presenteeism, including single-item global measures and multi-item instruments. In some studies using single-item global instruments may be more feasible. However, available global instruments differ in concept, recall period and reference. It is important to understand which of the measures have good psychometric properties before using them in clinical studies.ObjectivesTo assess the psychometric properties of four global presenteeism instruments.MethodsPatients with IA or OA were recruited via rheumatology outpatient clinics to a large international, longitudinal observational study including 8 European countries and Canada. Participants completed a survey at baseline, 1, 2, 3, 4 wks, 2 months and 3 months. The four global measures of presenteeism included: Work Productivity and Activity Impairment Questionnaire (WPAI), Work Productivity Scale–Rheumatoid Arthritis (WPS-RA), Work Ability Index (WAI) and the Quality*Quantity questionnaire (QQtotal/10) scale. To facilitate score interpretation the WAI and QQtotal were reversed. Pain was measured using an 11-point Likert scale. Spearman correlations were calculated between the presenteeism measures and the Workplace Activity Limitations Scale (WALS), a validated multi-item measure of presenteeism, and HAQ to evaluate construct validity (validity: r <0.50=low; r >0.50-<0.70=moderate; r >0.70=high). Test-retest reliability of the 4 presenteeism scales (baseline-1wk) was measured applying ICC in patients with stable disease (i.e. same pain score at baseline and 1wk) (reliability: ICC<0.40=poor; ICC 0.40-0.75=fair to good; ICC >0.75=excellent). Responsiveness during 3 months was measured comparing patients with improvement in pain score (>1 point improvement in pain score (~MCID pain)) with patients with no change or worsening in pain score. The two groups were compared applying Mann Whitney U test.ResultsThis international study included 550 patients with a mean age of 47.8 (SD 9.9) yrs and 61.4% were female. Mean (SD) disease duration since diagnosis was 10.8 (10.4) yrs and 91.2% had IA. Mean (SD) presenteeism scores at baseline were: WPAI=2.9 (2.7); WPS-RA=3.4 (2.7); WAI=2.7 (2.4); and QQtotal=3.1 (3.2). The correlations between the global measures and with WALS and HAQ were moderate to good, except for QQtotal and HAQ which was low (Table 1). In patients with the same stable pain scores at baseline-1wk (n=141) ICC scores were good to excellent, respectively: WPAI (0.771), WPS-RA (0.752), WAI (0.663), and QQtotal (0.650). An improvement in pain during the 3 month study duration was observed in 145/381 (38%) of the patients. In these patients a significant reduction in mean (SD) change presenteeism was observed for all four presenteeism scales compared to those with no change or worsening of the pain score: WPAI (-1.0 (2.37) vs 0.68 (2.40), p<0.01); WPS-RA (-0.76 (2.57) vs 0.43 (2.10), p<0.001); WAI (-0.09 (2.34) vs 0.41 (2.46), p<0.001); QQtotal (-0.57 (3.16) vs 0.79 (3.1), p<0.01).Table 1.WPAIWPS-RAWAIQQtotalWALSHAQWPAI-0.81640.59920.51840.62690.5592WPS-RA-0.58360.52170.60550.5669WAI-0.58660.52310.5168QQtotal-0.50250.4367ConclusionThe psychometric properties of all 4 global presenteeism scales were moderate to good, with slightly better scores for both the WPS-RA and WPAI instruments both measuring the impact of OA and IA on productivity.Disclosure of InterestsSuzanne Verstappen Consultant of: EUOSHA, Grant/research support from: AbbVie, BMS.

O03 ST97 Staphylococcus aureus and oxacillin resistance: an emerging challenge for microbiologists? JAC Antimicrob Resist 2022.

Abstract
Background The presence of cefoxitin and oxacillin resistance in Staphylococcus aureus isolates is suggestive of methicillin resistance (MRSA) with molecular detection of the mecA or mecC genes providing confirmation. The UK SMI and EUCAST guidelines for MRSA detection describe a subset of strains that exhibit reduced susceptibility to oxacillin and cefoxitin, though negative for mecA and mecC genes—frequently named borderline oxacillin-resistant S. aureus (BORSA). Local data noted a number of S. aureus isolates that matched the above phenotype leading to laboratory, clinical and epidemiological questions. Methods Routine samples were collected between August 2020 and April 2021 at West Midlands Health Security Agency Laboratory, Birmingham. If provisional results suggested an MRSA isolate, the following confirmatory tests were undertaken. Locally, clinical samples underwent susceptibility testing with cefoxitin disc diffusion and oxacillin gradient diffusion (MRSA screens) or Vitek 2 (non-MRSA screens). Isolates with discrepant results [susceptible to cefoxitin; resistant to oxacillin (MIC >2 mg/L) or vice versa] were sent to the reference laboratory at Colindale, UK for further testing, which included mecA or mecC gene detection by PCR and serotyping with Illumina sequencing for all isolates. Results In total, 53 isolates were sent to the reference lab of which 22 were confirmed to have an ST97 serotype. All 53 were negative by PCR for mecA and mecC genes. For the 22 isolates of ST97, local oxacillin MIC values ranged from 2 to 6 mg/L. Cefoxitin susceptibility was confirmed locally in all isolates. The 22 isolates were from 15 patients; wound swabs (n = 18); blood culture (n = 1), sputum (n = 1) and MRSA screen (n = 2). Median patient age was 48 years (IQR 38–59) with 5 being female and 10 male. A history of injecting drug use was documented in 53% (8/15). Conclusions BORSA remains a problem from a laboratory, clinical and infection control perspective. This work raises two important questions: what is the most appropriate local laboratory testing pathway and what is the clinical relevance of these isolates (i.e. can flucloxacillin be relied upon in treatment)? The ST97 serotype appears to be associated with skin and soft tissue infection and may be linked to people who inject drugs.

Polarisation-sensitive optical coherence tomography measurement of retardance in fibrosis, a non-invasive biomarker in patients with systemic sclerosis. Sci Rep 2022; 12:2893. [PMID: 35190594 PMCID: PMC8861061 DOI: 10.1038/s41598-022-06783-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Accepted: 01/31/2022] [Indexed: 12/23/2022] Open
Abstract
Polarisation-sensitive optical coherence tomography (PS-OCT) offers a novel, non-invasive method of assessing skin fibrosis in the multisystem disease systemic sclerosis (SSc) by measuring collagen retardance. This study aimed to assess retardance as a biomarker in SSc. Thirty-one patients with SSc and 27 healthy controls (HC) underwent PS-OCT imaging. 'Skin score' was assessed by clinical palpation (0-3 scale). A subset of ten patients and ten age/sex-matched HC had a biopsy and longitudinal imaging. Histological assessment included quantification of epidermal thickness, collagen content (to assess fibrosis) and matrix metalloproteinase (MMP) activity (in situ zymography). PS-OCT images were assessed for epidermal thickness (structure) and fibrosis (retardance). Positive correlation was observed between epidermal thickness as measured by histology and structural PS-OCT (r = 0.79; p < 0.001). Retardance was: HC mean 0.21 (SD 0.21) radian/pixel; SSc skin score 0, 0.30 (0.19); skin score 1, 0.11 (0.16); skin score 2, 0.06 (0.12); skin score 3, 0.36 (0.35). Longitudinal retardance decreased at one-week across groups, increasing at one-month for HC/skin score 0-1; HC biopsy site retardance suggests scarring is akin to fibrosis. Relationships identified between retardance with both biopsy and skin score data indicate that retardance warrants further investigation as a suitable biomarker for SSc-related fibrosis.

The Response of Layer Hen Productivity and Egg Quality to an Additional Limestone Source When Offered Diets Differing in Calcium Concentrations and the Inclusion of Phytase. Animals (Basel) 2021; 11:ani11102991.

Abstract
Simple Summary Dietary calcium is essential for optimal egg production and quality in laying hens, but high concentrations can impede the digestibility of other dietary components. The provision of limestone grit in addition to the main diet may help maintain overall calcium intake while allowing a reduction in dietary calcium levels. The impact of phytase, an enzyme that increases calcium availability in the gut, on the voluntary consumption of limestone grit is unknown. Here, the capacity for hens with access to a separate limestone grit source to modify Ca consumption when offered varying dietary Ca levels and phytase was evaluated. Dietary phytase reduced limestone grit consumption. Egg production was unaffected by reducing dietary calcium levels or the phytase addition. Eggshell measurements worsened in line with decreasing dietary calcium levels despite the provision of limestone grit. In summary, the provision of limestone grit resulted in comparable egg production but not eggshell quality in hens offered suboptimal levels of dietary calcium. Abstract Laying hens require substantial quantities of calcium (Ca) to maintain egg production. However, maintaining recommended dietary Ca through inclusion of limestone may impede nutrient digestibility, including that of other minerals. It was hypothesized that providing a separate source of dietary Ca in the form of limestone grit would preserve Ca intake of hens offered diets containing suboptimal Ca concentrations. Furthermore, the impact of dietary phytase at a “superdosing” inclusion rate on the voluntary consumption of limestone grit was evaluated. One hundred and forty-four laying hens (19 weeks of age) were assigned to one of six dietary treatments in a 3 × 2 factorial arrangement comprising three dietary Ca concentrations (40, 30, and 20 g/kg) and ±dietary phytase (3500 FYT/kg diet) on an ad libitum basis for six weeks. Limestone grit (3.4 ± 1.0 mm) was provided to all hens ad libitum. Hens offered diets containing phytase consumed significantly less limestone grit p = 0.024). Egg weight, rate of lay, and egg mass were unaffected by dietary treatment (p > 0.05). Egg shell weight % (p < 0.001), shell thickness (p < 0.001), and shell breaking strength (p < 0.01) decreased in line with dietary Ca levels. In summary, dietary superdosing with phytase reduced the consumption of a separate limestone source in individually housed, early lay ISA Brown hens. Egg shell quality variables but not egg production worsened in line with lower dietary Ca levels.

Black soldier fly larvae in broiler diets improve broiler performance and modulate the immune system. ACTA ACUST UNITED AC 2021; 7:695-706.

Abstract
Non-conventional feed ingredients are receiving more interest in their ability to increase farming efficiency, sustainability and animal performance. The objective of this study was to determine the optimal rate of inclusion level of the full-fat black soldier fly larvae (BSFL) in broiler diets and to evaluate their impact on performance, nutrient digestibility, and the immune system (blood cells and intraepithelial lymphocytes). A total of 400 male day-old Ross 308 broilers were randomly assigned to 5 treatment groups with 8 replicates each. Five inclusion levels of full-fat BSFL were investigated across starter (0, 2.5%, 5%, 7.5% and 10%), grower and finisher diets (0, 5%, 10%, 15% and 20%). All diets were formulated based on digestible amino acid values according to the Aviagen (2016) recommendations. A polynomial regression at different degrees was performed to analyse broiler performance parameters (body weight, body weight gain, feed intake, and feed conversion ratio), nutrient digestibility, and blood cell count. Intraepithelial lymphocyte population data was analysed performing univariate linear regression. During the entire experimental period (from 2 to 42 d), BSFL inclusion levels decreased the feed conversion ratio by 10% in broilers that received 20% BSFL in their diets (P < 0.05). Lymphocytes and white blood cell count decreased linearly by 47.7% and 35.9%, respectively, with up to 20% BSFL inclusion (P < 0.001). A 4-fold decrease in CD3+ T lymphocytes and a 9.7-fold decrease of CD3+CD8+ intestinal cytotoxic T lymphocytes occurred in broilers fed 20% BSFL compared to the control group. These findings suggest that the inclusion of BSFL can improve broiler performance and potentially reduce immune response energy expenditure in birds fed 20% BSFL for 42 d.

Abstract
The addition of cattle health and immunity traits to genomic selection indices holds promise to increase individual animal longevity and productivity, and decrease economic losses from disease. However, highly variable genomic loci that contain multiple immune-related genes were poorly assembled in the first iterations of the cattle reference genome assembly and underrepresented during the development of most commercial genotyping platforms. As a consequence, there is a paucity of genetic markers within these loci that may track haplotypes related to disease susceptibility. By using hierarchical assembly of bacterial artificial chromosome inserts spanning 3 of these immune-related gene regions, we were able to assemble multiple full-length haplotypes of the major histocompatibility complex, the leukocyte receptor complex, and the natural killer cell complex. Using these new assemblies and the recently released ARS-UCD1.2 reference, we aligned whole-genome shotgun reads from 125 sequenced Holstein bulls to discover candidate variants for genetic marker development. We selected 124 SNPs, using heuristic and statistical models to develop a custom genotyping panel. In a proof-of-principle study, we used this custom panel to genotype 1,797 Holstein cows exposed to bovine tuberculosis (bTB) that were the subject of a previous GWAS study using the Illumina BovineHD array. Although we did not identify any significant association of bTB phenotypes with these new genetic markers, 2 markers exhibited substantial effects on bTB phenotypic prediction. The models and parameters trained in this study serve as a guide for future marker discovery surveys particularly in previously unassembled regions of the cattle genome.

Abstract
INTRODUCTION Isolation of Exophiala species from sputum samples has become increasingly reported in Cystic Fibrosis (CF). However, the clinical significance of Exophiala spp. with regards to the paediatric CF population is unknown. METHODS A case control study was undertaken to compare CF children with and without chronic Exophiala spp. in their sputum samples. Demographic and clinical data were collected retrospectively for each case from the date of Exophiala isolation and for 12 months preceding isolation. Each case was compared to three age and year-matched controls. To determine the effect of Exophiala on clinical course, patients were then followed for 12 months post isolation. RESULTS In total, 27 of 244 eligible paediatric CF patients (11%) isolated Exophiala spp. on more than one occasion. There were no significant differences in the key clinical parameters: spirometry, mean number of intravenous (IV) antibiotic days and body mass index (BMI), between cases and controls (p = 0.91, p = 0.56 and p = 0.63 respectively). A higher proportion of cases isolated Candida spp. (67% vs 21%, p < 0.0001) and Aspergillus fumigatus (37% vs 26%, p = 0.37). There was no clinically significant difference in spirometry, mean number of IV antibiotic days and BMI in cases pre and post Exophiala spp. isolation. Posaconazole was the only drug used that successfully eradicated Exophiala. CONCLUSION Despite the frequent isolation of Exophiala spp. in this cohort, in most patients it is not associated with significant clinical deterioration. It does however seem to be associated with isolation of other fungi.

Abstract
Water kefir is a sparkling, slightly acidic fermented beverage produced by fermenting a solution of sucrose, to which dried fruits have been added, with water kefir grains. These gelatinous grains are a symbiotic culture of bacteria and yeast embedded in a polysaccharide matrix. Lactic acid bacteria, yeast and acetic acid bacteria are the primary microbial members of the sugary kefir grain. Amongst other contributions, species of lactic acid bacteria produce the exopolysaccharide matrix from which the kefir grain is formed, while yeast assists the bacteria by a nitrogen source that can be assimilated. Exactly which species predominate within the grain microbiota, however, appears to be dependent on the geographical origin of the grains and the fermentation substrate and conditions. These factors ultimately affect the characteristics of the beverage produced in terms of aroma, flavour, and acidity, for example, but can also be controlled and exploited in the production of a beverage of desired characteristics. The production of water kefir has traditionally occurred on a small scale and the use of defined starter cultures is not commonly practiced. However, as water kefir increases in popularity as a beverage - in part because of consumer lifestyle trends and in part due to water kefir being viewed as a health drink with its purported health benefits - the need for a thorough understanding of the biology and dynamics of water kefir, and for defined and controlled production processes, will ultimately increase. The aim of this review is to provide an update into the current knowledge of water kefir.

Abstract
Advances in technology, methodology, and deep phenotyping are increasingly driving the understanding of the pathologic basis of disease. Improvements in patient identification and treatment are impacting survival. This is true in endocrinology and inborn errors of metabolism, where disease-modifying therapies are developing. Inherent to this evolution is the increasing awareness of the respiratory manifestations of these rare diseases. This review updates clinicians, stratifying diseases spirometerically; pulmonary hypertension and diseases with a predisposition to recurrent pulmonary infection are discussed. This division is artificial; many diseases have multiple pathologic effects on respiration. This review does not cover the impact of obesity.

The evolution of pulmonary function in childhood onset Mucopolysaccharidosis type I. Mol Genet Metab 2021; 132:94-99. [PMID: 32713717 DOI: 10.1016/j.ymgme.2020.07.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 06/30/2020] [Accepted: 07/07/2020] [Indexed: 11/24/2022]
Abstract
Respiratory outcomes in Mucopolysaccharidosis Type I (MPS I), have mainly focused on upper airway obstruction, with the evolution of the restrictive lung disease being poorly documented. We report the long-term pulmonary function outcomes and examine the potential factors affecting these in 2 cohorts of MPS I patients, those who have undergone Haematopoietic Stem Cell Transplantation (HSCT) and those treated with Enzyme Replacement Therapy (ERT). The results were stratified using the American Thoracic Society (ATS) guidelines. 66 patients, capable of adequately performing testing, were identified by a retrospective case note review, 46 transplanted (45 Hurler, 1 Non-Hurler) and 20 having ERT (17 Non-Hurler and 3 Hurler diagnosed too late for HSCT). 5 patients died; 4 in the ERT group including the 3 Hurler patients. Overall 14% of patients required respiratory support (non-invasive ventilation (NIV) or supplemental oxygen)) at the end of follow up. Median length of follow-up was 12.2 (range = 4.9-32) years post HSCT and 14.34 (range = 3.89-20.4) years on ERT. All patients had restrictive lung disease. Cobb angle and male sex were significantly associated with more severe outcomes in the HSCT cohort, with 49% having severe to very severe disease. In the 17 Non-Hurler ERT treated patients there was no variable predictive of severity of disease with 59% having severe to very severe disease. During the course of follow up 67% of the HSCT cohort had no change or improved pulmonary function as did 52% of the ERT patients. However, direct comparison between therapeutic modalities was not possible. This initial evidence would suggest that a degree of restrictive lung disease is present in all treated paediatrically diagnosed MPS I and is still a significant cause of morbidity, though further stratification incorporating diffusing capacity for carbon monoxide (DLCO) is needed.

Abstract
As the Advanced Gas-cooled Reactors approach the end of generation, research and characterisation are required to support the decommissioning strategy. Radiological data for AGR graphite are negligible and the radiological inventory of the AGR core and other graphite components rely on activation modelling. This is the first study of C-14 activity and its release behaviour in AGR core graphite and its associated carbonaceous deposits and provides valuable information that can support decommissioning activities. In combination with corresponding studies on Magnox core graphite, significant understanding is attained on the main C-14 precursors in the graphite and the deposits. In addition, this study reports C-14, H-3 and gamma spectrometry data on AGR graphite fuel sleeves. This is a waste stream that is currently stored in heavily engineered stores at a significant cost. The data indicate that alternative storage and disposal options with a lower environmental and financial impact are worth considering.

Excreta biomarkers in response to different gut barrier dysfunction models and probiotic supplementation in broiler chickens. PLoS One 2020; 15:e0237505.

Abstract
Increased intestinal permeability (IP) and inflammation are both linked with functionality of the intestinal barrier and in particular enterocytes. Currently, almost all assessment methods of the intestinal barrier function are invasive. The present study aimed to quantify selected proteins as novel biomarkers in excreta of broiler chickens to facilitate non-invasive assessment of gut barrier function using enzyme-linked immunosorbent assays (ELISA). It was further hypothesised that probiotics as feed additives may counteract gut barrier dysfunction. A 3 × 2 factorial arrangement of treatments was used with the main factors being gut barrier dysfunction models (control, rye-based diet, and dexamethasone-DEX) with and without probiotic supplementation (a three-strain Bacillus) using 72 male Ross 308 day-old chickens. Each of the 6 experimental treatments was replicated 12 times. On d 21 of age, fluorescein isothiocyanate dextran (FITC-d) uptake into serum was examined to test IP. Fresh excreta samples were collected on d 20. The biomarkers included alpha-1 antitrypsin (A1AT), intestinal fatty acid binding protein (I-FABP), lipocalin-2 (LCN2), fibronectin (FN), intestinal alkaline phosphatase (IAP), ovotransferrin (OVT) and superoxide dismutase [Cu-Zn] (SOD1). Only DEX increased (P<0.001) FITC-d passage to the blood on d 21 of age, indicating a greater IP. The excreta concentrations of A1AT, I-FABP and SOD1 were unaltered by the experimental treatments. DEX increased (P<0.05) FN concentration in excreta compared with control birds. Conversely, inclusion of rye in the diet reduced (P<0.05) FN but increased (P<0.001) OVT in excreta. Independently, DEX decreased IAP (P<0.05) in excreta compared with control and rye-fed birds. The excreta concentration of LCN2 tended (P = 0.086) to increase in birds injected by DEX. There was no demonstrable effect of probiotic addition on any of the studied parameters. Among the tested biomarkers, FN, IAP, and LCN2 revealed promise as biomarkers of intestinal barrier function quantified by ELISA kits.

A Dietary Sugarcane-Derived Polyphenol Mix Reduces the Negative Effects of Cyclic Heat Exposure on Growth Performance, Blood Gas Status, and Meat Quality in Broiler Chickens. Animals (Basel) 2020; 10:ani10071158. [PMID: 32650461 PMCID: PMC7401608 DOI: 10.3390/ani10071158] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 06/26/2020] [Accepted: 07/02/2020] [Indexed: 12/31/2022] Open
Abstract
Simple Summary Heat stress is a main reason of systemic oxidative stress, which compromises broiler meat production and quality. To improve the productivity of poultry meat production, studies have investigated different heat stress amelioration strategies. Among these strategies, low-cost feed supplementations are introduced to potentially reduce the negative effects of heat stress. Previous studies have also investigated the effects of different antioxidants on growth performance and meat quality, while a limited number of studies have been made regarding the impacts of the polyphenols at different doses. Polyphenols with antioxidant properties have positive effects against oxidative stress, and are naturally available in high amounts in plants, which makes them a novel feed supplementation for improving meat production as well as meat quality in heat-stressed broiler chickens. Therefore, this study attempted to investigate the effects of different doses of polyphenols supplementation on growth performance, physiological responses, and meat quality in broiler chickens exposed to cyclic heat stress. Abstract Heat stress (HS) compromises growth performance and meat quality of broiler chickens by interrupting lipid and protein metabolism, resulting in increased oxidative damages. The experiment attempted to investigate whether dietary polyphenols (Polygain (POL)) could ameliorate the aforementioned adverse effects of HS on performance and meat quality. One hundred and twenty one day-old-male chicks were allocated to two temperature conditions, thermoneutral (TN) or HS, and fed with either a control diet (CON) or the CON plus four different doses of POL (2, 4, 6 and 10 g/kg). Heat stress caused respiratory alkalosis as evidenced by increased rectal temperature (p < 0.001) and respiration rate (p < 0.001) due to increased blood pH (p < 0.001). Heat stress decreased final body weight (p = 0.061) and breast muscle water content (p = 0.013) while POL improved both (p = 0.002 and p = 0.003, respectively). Heat stress amplified muscle damages, indicated by increased thiobarbituric acid reactive substances (p < 0.001) and reduced myofibril fragmentation index (p = 0.006) whereas POL improved both (p = 0.037 and p = 0.092, respectively). Heat stress impaired meat tenderness (p < 0.001) while POL improved it (p = 0.003). In conclusion, HS impaired growth performance and meat quality whereas POL ameliorated these responses in a dose-dependent manner, and effects of POL were evident under both temperature conditions.

Abstract
For much of the 20th century, the Mersey in North West England was one of the worst polluted estuaries in Europe. Water from a range of polluting industries plus domestic sewage was discharged into the Mersey Catchment and Estuary. Recovery came through a concerted clean-up campaign and tightening environmental regulations, partly driven by European Commission Directives, coupled with de-industrialisation from the 1970s onward. Recovery of oxygen levels in the Estuary led to the return of a productive ecosystem. This led to conservation designations, but also concerns about transfer of pollutants to higher trophic levels in fish, birds and humans. As part of urban renewal, ecosystems in disused dock basins were restored using mussel biofiltration and artificial de-stratification, facilitating commercial redevelopment and creation of a tourist destination. The degradation and recovery of the Mersey from peak-pollution in the mid-20th century is put in the context of wider environmental change and briefly compared to other systems to develop a hysteresis model of degradation and recovery, often to novel ecosystems.

Abstract
BACKGROUND The coronavirus disease 2019 pandemic has necessitated rapid adaptations to all levels of clinical practice. Recently produced guidelines have suggested additional considerations for tracheostomy and advocated full personal protective equipment, including filtering facepiece code 3 masks. Air seal with filtering facepiece code 3 masks is often challenging, and full-face respirators and powered air-purifying respirators with hoods need to be employed. The infection prevention benefits of this equipment are accompanied by potential issues in communication. OBJECTIVE In an attempt to minimise surgical error through miscommunication, the authors sought to introduce a simple sign language system that could be used as an adjunct during surgery. RESULTS Following evaluation of pre-existing sign language platforms and consideration of multiple surgical factors, 14 bespoke hand signals were ultimately proposed. CONCLUSION Whilst this novel sign language system aims to bridge the communicative gap created by additional personal protective equipment, further development and validation of the proposed tool might be beneficial.

Abstract
In a 2 × 2 factorial design, 60 male Ross-308 broilers were fed either a control or 1 g/kg betaine diet and housed under thermoneutral (TN) or heat stress (HS) conditions. Broilers were acclimated to diets for 1 week under TN (25 °C), then either kept at TN or HS, where the temperature increased 8 h/day at 33 °C and 16 h/day at 25 °C for up to 10 days. Respiration rate (RR) was measured at four time points, and on each of 1, 2, 3, 7 and 10 days of HS, 12 broilers were injected with 0.5 mg/kg of Evans Blue Dye (EBD) solution to quantify regional changes in tissue damage. Betaine was quantified in tissues, and ileal damage was assessed via morphometry and transepithelial resistance (TER). Heat stress elevated RR (p < 0.001) and resulted in reduced villous height (p = 0.009) and TER (p < 0.001), while dietary betaine lowered RR during HS (p < 0.001), increased betaine distribution into tissues, and improved ileal villous height (p < 0.001) and TER (p = 0.006). Heat stress increased EBD in the muscle and kidney of chickens fed the control diet but not in those receiving betaine. Overall, these data indicate that supplemented betaine is distributed to vital organs and the gastrointestinal tract, where it is associated with improved tolerance of HS. Furthermore, EBD markers help reveal the effects of HS on organs dysfunction.

Abstract
Mucopolysaccharidoses type IVA (Morquio disease) is a rare, autosomal recessive lysosomal storage disease that causes both obstructive and restrictive airway pathology, with respiratory failure being the primary cause of death. This article provides original data on the longitudinal characterization of pulmonary function changes in children with Mucopolysaccharidoses (MPS) IVA by presenting the data and nuanced trends of changes from sequential spirometry and oximetry. The sample size included 16 subjects, 13 had undergone enzyme replacement therapy (ERT), three had not undergone ERT treatment. A total of 180 individual plots are presented for spirometry variables (FEV1, FEV1 [%Pred] FVC, FVC [%Pred] and FEV1/FVC), 6MWT and oximetry variables (median %Spo2, ODI 3%, mean nadir 3%, ODI 4%, mean nadir 4% and min dip SpO2 [%]); over a nine-year period at a single quaternary paediatric metabolic centre. This data has been made public and has utility to clinicians and researchers due to the following: [1,2] by providing the first comprehensive report of detailed changes in pulmonary function in children with MPS IVA, with and without ERT; [1-3] as well as changes in pulmonary function following the institution of non-invasive ventilation (NIV) and adenotonsillectomy. The data presented is related to the research article by Kenth et al. "The Characterization of Pulmonary Function in Patients with Mucopolysaccharidoses IVA: A Longitudinal Analysis".

Abstract
Introduction Mucopolysaccharidosis (MPS) type IVA is a rare, autosomal recessive lysosomal storage disease causing substrate accumulation in various organs and tissues. MPS IVA is associated with both obstructive and restrictive airway disease, with the former often resulting in sleep disordered breathing (SDB). Respiratory failure is a primary cause of death in this condition. The aim of this study was to characterise and catalogue the long-term respiratory changes in patients with MPS IVA treated with, or without, enzyme replacement therapy (ERT). Methods In this retrospective, longitudinal, repeated-measures cohort study, descriptive statistics and non-parametric correlation were performed for demographic, respiratory function and oximetry variables over a study period from January 2009 to December 2018. Composite clinical endpoints used in this study for evaluating pulmonary function included spirometry variables (FEV1, FEV1 [%Pred] FVC, FVC [%Pred] and FEV1/FVC), oximetry variables (median %Spo2, ODI 3%, mean nadir 3%, ODI 4%, mean nadir 4% and min dip SpO2 [%]) and 6MWT to assess functional exercise capacity and thus integrated cardiopulmonary function. Results Sequential spirometry and oximetry values were collected from 16 patients, of which 13/16 were ERT treated. In general, during the study period there was a global reduction in static spirometry values in all subjects, as well as cardiorespiratory function as assessed by the 6MWT, with the decline being delayed in the ERT group. Oximetry changed to a minor degree over time in the ERT group, whereas it declined in the non-ERT group. FEV1, FVC [%predicted] and ODI 3% exhibited a strong, combined positive correlation (r 0.74–95% CI 0.61 to 0.83; p < .0001). Non-invasive ventilation (NIV) and adenotonsillectomy appeared more effective in the ERT group, either improving pulmonary function or attenuating deterioration. Conclusions Whilst spirometry values showed a gradual decline across all groups, oximetry showed modest improvement in respiratory function. The amalgamation of FEV1, FVC [%predicted] and ODI 3% appeared predictive of changes in respiratory function in this study, suggestive as being composite endpoints for monitoring disease progression as well as guiding response to ERT in MPS IVA patients.

Abstract
BACKGROUND Inclusion cell disease (I-cell) is a rare autosomal recessive metabolic disease involving multiple organ systems, associated with a severely restricted life expectancy. No curative therapy is currently available, with management aimed at symptom palliation. METHODS We present a retrospective, single-centre, case series of children referred to a tertiary paediatric metabolic service. The clinical presentation, demographics, genetics and natural history of the condition are investigated. RESULTS Five patients with I-cell disease were referred over a 10-year period. All patients were born with dysmorphic features and had a family history of I-cell disease on further exploration. Phenotypic variation was seen within patients with the same genetic profile. Airway problems were common with 100% of the documented sleep oximetry studies suggesting sleep-disordered breathing. Of the two patients who had tracheal intubation anaesthetic difficulties we encountered, one required intraoperative reintubation, and one suffered a failed intubation with subsequent death. All five patients required oxygen therapy with the use of CPAP and BiPAP also seen. Feeding issues were almost universal with four of the five patients requiring nasogastric feeding. Four patients had died in the 10-year period with a mean life expectancy of 36 months. Cause of death for three of the four patients was respiratory failure. CONCLUSIONS Airway problems, including sleep-disordered breathing, were ubiquitous in this cohort of children. Any intervention requiring a general anaesthetic needs careful multidisciplinary consideration due to significant associated risks and possibly death. Management as a result is generally non-surgical and symptomatic. This case series demonstrates universal involvement of the airway and respiratory systems, an important consideration when selecting meaningful outcomes for future effectiveness studies of novel therapies.

Abstract
IntroductionComplex interventions are common in palliative care (PC) but are difficult to evaluate. Complementary therapies (CT) are one type of widely-used complex intervention for which there is inconclusive evidence. No systematic review has been conducted in PC of trials or of qualitative studies of patients’ views of CTs. There are novel approaches with established exemplars of using both types of reviews to help develop more clinically appropriate interventions. These approaches are in their infancy in PC research and have much to offer the specialism.AimsUsing our on-going review on CT we present as an exemplar in PC an approach to draw together the findings of trials and qualitative studies in a data table (matrix) to contrast what patients value and want with how the intervention is tested.MethodsWe sought trials on the effectiveness of CT and qualitative studies on patients’ perspectives about these therapies. Our primary outcomes for trials included anxiety. Eight databases were searched in 2017. Citations and full-text papers were reviewed to identify relevant studies. Meta-analyses pooled trial data where appropriate and a thematic synthesis is being undertaken to understand patient experience. These findings will be combined in a matrix to explore similarities and differences.Results19 trials and five qualitative studies were included. Data analysis and development of the matrix which includes intervention content and patients’ needs is currently underway. We will present the final matrix framework.ConclusionsOur approach demonstrates a potential way in PC to enhance development of practice appropriate complex interventions.

rpoB gene sequencing highlights the prevalence of an E. miricola cluster over other Elizabethkingia species among UK cystic fibrosis patients. Diagn Microbiol Infect Dis 2017; 90:109-114.

Abstract
Difficulties in distinguishing species of the Elizabethkingia genus by MALDI-TOF prompted use of rpoB sequencing to investigate species distribution among 44 isolates from cystic fibrosis (CF) patients. Forty-three isolates from 38 patients formed a cluster comprising E. miricola and proposed novel species E. bruuniana sp. nov., the exception clustering with proposed species E. ursingii sp. nov., also part of this wider cluster. All 44 isolates were PCR-positive for urease gene ureG, whereas only one of 23 E. anophelis isolates from non-CF patients was positive, suggesting that this gene is largely associated with the E. miricola cluster. Antibiotic susceptibilities of 12 CF isolates revealed all were resistant to beta-lactams with the exception of piperacillin-tazobactam, and were only susceptible to minocycline and co-trimoxazole. Pulsed-field gel electrophoresis analysis revealed 4 shared strains among 17 CF patients in one pediatric clinic, but epidemiological investigations did not support patient-to-patient transmission except between one sibling pair.

A qualitative study of the role of Australian general practitioners in the surgical management of obesity. Clin Obes 2017; 7:231-238.

Abstract
General practitioners (GPs) are increasingly managing patients with class 2 and 3 obesity (body mass index [BMI] > 35 and 40 kg/m2 , respectively). Bariatric surgery is considered for patients with class 2 obesity and comorbidities or class 3 obesity where sustained weight loss using non-surgical interventions has not been achieved. In Australia, GPs facilitate access to surgery through referral processes, but the nature of GP involvement in bariatric pre- and post-surgery care is currently unclear. This qualitative study involved 10 in-depth interviews with GPs and 20 interviews with adults who had all undergone laparoscopic adjustable gastric banding (LAGB) for weight management in Tasmania, Australia. Interviews were transcribed and analysed thematically. Referrals for bariatric surgery commonly occurred at the patient's request or to manage comorbidity. Consistent with previous studies, for GPs, referral patterns were influenced by previous case experience and patients' financial considerations. Accessibility of surgery was also a consideration. Post-surgery, there was a lack of clarity about the role of GPs, with patients generally preferring the surgical team to manage the LAGB. In bariatric surgery, patient preference for surgery, access and comorbidity are key drivers for referral and post-surgical monitoring and support. Greater role clarity and enhanced collaboration between surgeons, GPs and patients following surgery is likely to enhance the experience and outcomes for patients.

Fine-mapping host genetic variation underlying outcomes to Mycobacterium bovis infection in dairy cows. BMC Genomics 2017; 18:477. [PMID: 28646863 PMCID: PMC5483290 DOI: 10.1186/s12864-017-3836-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2016] [Accepted: 05/31/2017] [Indexed: 12/01/2022] Open
Abstract
BACKGROUND Susceptibility to Mycobacterium bovis infection in cattle is governed in part by host genetics. However, cattle diagnosed as infected with M. bovis display varying signs of pathology. The variation in host response to infection could represent a continuum since time of exposure or distinct outcomes due to differing pathogen handling. The relationships between host genetics and variation in host response and pathological sequelae following M. bovis infection were explored by genotyping 1966 Holstein-Friesian dairy cows at 538,231 SNPs with three distinct phenotypes. These were: single intradermal cervical comparative tuberculin (SICCT) test positives with visible lesions (VLs), SICCT-positives with undetected visible lesions (NVLs) and matched controls SICCT-negative on multiple occasions. RESULTS Regional heritability mapping identified three loci associated with the NVL phenotype on chromosomes 17, 22 and 23, distinct to the region on chromosome 13 associated with the VL phenotype. The region on chromosome 23 was at genome-wide significance and candidate genes overlapping the mapped window included members of the bovine leukocyte antigen class IIb region, a complex known for its role in immunity and disease resistance. Chromosome heritability analysis attributed variance to six and thirteen chromosomes for the VL and NVL phenotypes, respectively, and four of these chromosomes were found to explain a proportion of the phenotypic variation for both the VL and NVL phenotype. By grouping the M. bovis outcomes (VLs and NVLs) variance was attributed to nine chromosomes. When contrasting the two M. bovis infection outcomes (VLs vs NVLs) nine chromosomes were found to harbour heritable variation. Regardless of the case phenotype under investigation, chromosome heritability did not exceed 8% indicating that the genetic control of bTB resistance consists of variants of small to moderate effect situated across many chromosomes of the bovine genome. CONCLUSIONS These findings suggest the host genetics of M. bovis infection outcomes is governed by distinct and overlapping genetic variants. Thus, variation in the pathology of M. bovis infected cattle may be partly genetically determined and indicative of different host responses or pathogen handling. There may be at least three distinct outcomes following M. bovis exposure in dairy cattle: resistance to infection, infection resulting in pathology or no detectable pathology.

The support needs of patients waiting for publicly funded bariatric surgery - implications for health service planners. Clin Obes 2017; 7:46-53.

Abstract
The objective of this study was to investigate the experience of waiting for publicly funded bariatric surgery in an Australian tertiary healthcare setting. Focus groups and individual interviews involving people waiting for or who had undergone publicly funded bariatric surgery were audio-recorded, transcribed and analysed thematically. A total of 11 women and 6 men engaged in one of six focus groups in 2014, and an additional 10 women and 9 men were interviewed in 2015. Mean age was 53 years (range 23-66); mean waiting time was 6 years (range 0-12), and mean time since surgery was 4 years (range 0-11). Waiting was commonly reported as emotionally challenging (e.g. frustrating, depressing, stressful) and often associated with weight gain (despite weight-loss attempts) and deteriorating physical health (e.g. development of new or worsening obesity-related comorbidity or decline in mobility) or psychological health (e.g. development of or worsening depression). Peer support, health and mental health counselling, integrated care and better communication about waitlist position and management (e.g. patient prioritization) were identified support needs. Even if wait times cannot be reduced, better peer and health professional supports, together with better communication from health departments, may improve the experience or outcomes of waiting and confer quality-of-life gains irrespective of weight loss.
