Abstract
Light is essential for photosynthesis; however, excess light can increase the accumulation of photoinhibitory reactive oxygen species that reduce photosynthetic efficiency. Plants have evolved photoprotective non-photochemical quenching (NPQ) pathways to dissipate excess light energy. In tobacco and soybean (C3 plants), overexpression of three NPQ genes, violaxanthin de-epoxidase (VDE), Photosystem II Subunit S (PsbS), and zeaxanthin epoxidase (ZEP), hereafter VPZ, resulted in faster NPQ induction and relaxation kinetics, and increased crop yields in field conditions. NPQ is well-studied in C3 plants; however, NPQ and the translatability of the VPZ approach in C4 plants is poorly understood. The green foxtail Setaria viridis is an excellent model to study photosynthesis and photoprotection in C4 plants. To understand the regulation of NPQ and photosynthesis in C4 plants, we performed transient overexpression in Setaria protoplasts and generated (and employed) stable transgenic Setaria plants overexpressing one of the three Arabidopsis NPQ genes or all three NPQ genes (AtVPZ lines). Overexpressing (OE) AtVDE and AtZEP in Setaria produced similar results as in C3 plants, with increased or reduced zeaxanthin (thus NPQ), respectively. However, overexpressing AtPsbS appeared to be challenging in Setaria, with largely reduced NPQ in protoplasts and under-represented homozygous AtPsbS-OE lines, potentially due to competitive and tight heterodimerization of AtPsbS and SvPsbS proteins. Furthermore, Setaria AtVPZ lines had increased zeaxanthin, faster NPQ induction, higher NPQ level, but slower NPQ relaxation. Despite this, AtVPZ lines had improved growth as compared to wildtype under several conditions, especially high temperatures, which is not related to the faster relaxation of NPQ but may be attributable to increased zeaxanthin and NPQ in C4 plants. Our results identified shared and unique characteristics of the NPQ pathway in C4 model Setaria as compared to C3 plants and provide insights to improve C4 crop yields under fluctuating environmental conditions.

Development and evaluation of a high-fidelity, multi-disciplinary simulation training course for high-consequence infectious diseases using fluorescence visualization. J Hosp Infect 2024; 157:1-9. [PMID: 39732368 DOI: 10.1016/j.jhin.2024.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2024] [Revised: 11/11/2024] [Accepted: 12/08/2024] [Indexed: 12/30/2024]
Abstract
BACKGROUND High-consequence infectious diseases (HCIDs) include contact-transmissible viral haemorrhagic fevers and airborne-transmissible infections such as Middle Eastern Respiratory Syndrome. Assessing suspected HCID cases requires specialized infection control measures including patient isolation, personal protective equipment (PPE), and decontamination. There is need for an accessible course for NHS staff to improve confidence and competence in using HCID PPE outside specialist HCID centres. AIM To produce and evaluate a training course for National Health Service (NHS) staff on recognition and assessment of patients with suspected HCID infection. METHODS We developed a multi-disciplinary course blending online learning with in-person, high-fidelity simulation using a manikin which employs fluorescent tracers to simulate airborne, contact, and fomite transmission. This facilitates visualization of contamination pre- and post-PPE removal and supports team-based debrief of performance. Training culminated in competency-based assessment. Educational effectiveness was evaluated through curriculum-linked pre- and post-course tests, and self-rated confidence using Likert scales. FINDINGS Between December 2022 and April 2024 180 nurses, specialty registrars and consultants were trained. Educational effectiveness was evaluated in 60 consecutive participants between December 2022 and April 2023. Pre- and post-course assessments revealed significant improvements in knowledge (mean score 61% vs 83%, P<0.0001). Pre-course, 36% of learners reported feeling confident in HCID PPE donning and doffing, rising to 97% post-course. Participants unanimously rated the learning experience as high- or very-high quality. CONCLUSION This course, incorporating ultraviolet markers for contamination visualization, represents a novel approach outside military settings. The results demonstrate its effectiveness as an educational intervention, improving staff confidence and competence in PPE use.

Abstract
BACKGROUND Neonatal near-miss (NNM) can be considered as an end of a spectrum that includes stillbirths and neonatal deaths. Clinical audits of NNM might reduce perinatal adverse outcomes. The aim of this review is to evaluate the effectiveness of NNM audits for reducing perinatal mortality and morbidity and explore related contextual factors. METHODS PubMed, Embase, Scopus, CINAHL, LILACS and SciELO were searched in February/2023. Randomized and observational studies of NNM clinical audits were included without restrictions on setting, publication date or language. PRIMARY OUTCOMES perinatal mortality, morbidity and NNM. SECONDARY OUTCOMES factors contributing to NNM and measures of quality of care. Study characteristics, methodological quality and outcome were extracted and assessed by two independent reviewers. Narrative synthesis was performed. RESULTS Of 3081 titles and abstracts screened, 36 articles had full-text review. Two studies identified, rated, and classified contributing care factors and generated recommendations to improve the quality of care. No study reported the primary outcomes for the review (change in perinatal mortality, morbidity and NNM rates resulting from an audit process), thus precluding meta-analysis. Three studies were multidisciplinary NNM audits and were assessed for additional contextual factors. CONCLUSION There was little data available to determine the effectiveness of clinical audits of NNM. While trials randomised at patient level to test our research question would be difficult or unethical for both NNM and perinatal death audits, other strategies such as large, well-designed before-and-after studies within services or comparisons between services could contribute evidence. This review supports a Call to Action for NNM audits. Adoption of formal audit methodology, standardised NNM definitions, evaluation of parent's engagement and measurement of the effectiveness of quality improvement cycles for improving outcomes are needed.

Abstract
The world of work over the past 3 years has been characterized by a great reset due to the COVID-19 pandemic, giving an even more central role to scholarly discussions of ethics and the future of work. Such discussions have the potential to inform whether, when, and which work is viewed and experienced as meaningful. Yet, thus far, debates concerning ethics, meaningful work, and the future of work have largely pursued separate trajectories. Not only is bridging these research spheres important for the advancement of meaningful work as a field of study but doing so can potentially inform the organizations and societies of the future. In proposing this Special Issue, we were inspired to address these intersections, and we are grateful to have this platform for advancing an integrative conversation, together with the authors of the seven selected scholarly contributions. Each article in this issue takes a unique approach to addressing these topics, with some emphasizing ethics while others focus on the future aspects of meaningful work. Taken together, the papers indicate future research directions with regard to: (a) the meaning of meaningful work, (b) the future of meaningful work, and (c) how we can study the ethics of meaningful work in the future. We hope these insights will spark further relevant scholarly and practitioner conversations.

Abstract
OBJECTIVE To assess the association between anatomical location of contamination and mortality in dogs with gastrointestinal and biliary origin of septic peritonitis. METHODS Medical records at two private referral hospitals between 2003 and 2020 were retrospectively reviewed. Cases were included if the origin of contamination was confirmed intraoperatively within the gastrointestinal or biliary tract. Cases were excluded if the dog died or was euthanized intraoperatively or where the data regarding the origin of contamination were not available. The association of anatomical origin with survival was assessed specifying the locations as stomach, small intestine, large intestine and biliary tract. The gastrointestinal tract origin was further subdivided into pylorus, nonpylorus, duodenum, jejunum, ileum, caecum and colon. RESULTS The overall survival rate was 75.9% (n = 44/58). There were no significant differences in survival among different anatomical origins of contaminations before or after subdivision (P = 0.349 and 0.832, respectively). Also, there was no association between isolated microorganism species in microbiological culture and the anatomical origin (P = 0.951) and the microorganism species was not associated with survival (P = 0.674). CONCLUSIONS There was no association between anatomical location of leakage, microorganism species and survival although further studies are warranted to analyse the relationships between anatomical leakage site and microorganism species as well as microorganism species and mortality.

Abstract
BACKGROUND The UK High-Consequence Infectious Diseases (HCID) Network of high-level isolation units provides care for patients with contact- or airborne-transmissible highly infectious and highly dangerous diseases. In most HCID units, the healthcare workers (HCWs) wear personal protective equipment (PPE) ensembles incorporating a powered air-purifying respirator (PAPR) for head and respiratory protection. Some PAPRs have components worn outside/over other PPE, necessitating decontamination of re-usable elements. Two alternative PAPRs, with all re-usable elements worn under PPE, were trialled in this study. AIM To undertake scenario-based testing of PAPRs and PPE to determine usability, comfort and ability to remove contaminated PPE without personal cross-contamination. METHODS Trained healthcare volunteers (N=20) wearing PAPR/PPE ensembles were sprayed with ultraviolet fluorescent markers. They undertook exercises to mimic patient care, and subsequently, after doffing the contaminated PPE following an established protocol, any personal cross-contamination was visualized under ultraviolet light. Participants also completed a questionnaire to gauge how comfortable they found the PPE. FINDINGS AND CONCLUSIONS The ensembles were tested under extreme 'worst case scenario' conditions, augmented by physical and manual dexterity tests. Participating volunteers considered the exercise to be beneficial in terms of training and PPE evaluation. Data obtained, including feedback from questionnaires and doffing buddy observations, supported evidence-based decisions on the PAPR/PPE ensemble to be adopted by the HCID Network. One cross-contamination event was recorded in the ensemble chosen; this could be attributed to doffing error, and could therefore be eliminated with further practice.

Abstract
BACKGROUND The use of musculoskeletal ultrasound (MSKUS) for point-of-care (POC) evaluation of hemophilic arthropathy is growing rapidly. However, the extent to which MSKUS influences clinical treatment decisions is unknown. METHODS We conducted a three-year, prospective, multi-center study at three hemophilia treatment centers in the United States to evaluate the utilization of POC-MSKUS for routine clinical decision-making in adult persons with hemophilic arthropathy. Bilateral elbows, knees and ankles were assessed clinically [Hemophilia Joint Health Score (HJHS)] and with POC-MSKUS by the Joint TissueActivity and Damage Exam (JADE) protocol at baseline and approximately annually for two additional times. Treatment decisions, including physical therapy (PT) and "medical" (joint injections/aspirations, referrals to orthopedics, changes/adjustments of hemostatic plans, and use of oral anti-inflammatory medications) were recorded in relation to POC-MSKUS. RESULTS Forty-four persons [median age 37 years (IQR 29, 51)], mostly with severe Hemophilia A on clotting factor prophylaxis, completed 129 visits, yielding 792 joint exams by POC-MSKUS and HJHS [median at baseline 27 (IQR 18, 42)] over a median follow up of 584 days (range: 363 to 1072). Among 157 management decisions, 70% were related to PT plans (n = 110) and 30% were "medical". Point-of-care MSKUS influenced 47/110 (43%) PT plans, mostly informing treatment of specific arthropathic joints (45/47 plans) in patients with high HJHS. Physical therapy plans influenced by POC-MSKUS directed more manual therapy/therapeutic exercises, while plans based on physical exam were focused more on global exercises and wellness. Treatment decisions were mostly based on the identification of specific musculoskeletal abnormalities visualized by POC-MSKUS. Of note 20/47 (43%) POC-MSKUS plans included de-escalation strategies, thereby reducing exercise intensity, mostly for joint instability and subclinical hemarthroses. Point-of-care MSKUS also informed 68% (32/47) of "medical" decisions, surprisingly mostly for injections/aspirations and referrals to orthopedics, and not for adjustments of hemostatic treatment. Although not formally studied, ultrasound images were used frequently for patient education. CONCLUSION Routine joint evaluations with POC-MSKUS resulted in few changes regarding medical management decisions but had a profound effect on the formulation of PT plans. Based on these findings, new studies are essential to determine the benefit of MSKUS-informed management plans on joint health outcomes.

HEALTH & SOCIAL CARE IN THE COMMUNITY 2022; 30:e5560-e5569.

Abstract
International health and social care systems are experiencing unprecedented pressure and demand. 'Single-handed care' initiatives seek to identify whether all or part of a homecare package involving more than one care worker can be safely reduced to a single worker. Little is known about these initiatives across local authorities. The aim of this study was to identify, describe and explain current processes and practices for single-handed care initiatives and double-handed homecare reviews. An electronic survey link was sent to each local authority with social care responsibilities in England. The questions covered a range of areas in relation to single-handed care processes and included a combination of pre-coded and free-text responses. Responses were received from 76 (50%) local authorities. Findings were that over 12,000 reviews were reported within a year with a median of 141 (IQR 45-280) from 53 authorities that provided figures. Reviews were usually led by a local authority occupational therapist. On average, 540 min was spent per review, including conducting and organising the review, documentation, and travel. In nearly half the authorities, double handed care remained at least partially in place following at least 80% of the reviews and remained wholly in place following at least 60%. Local authorities also reported some resistance from homecare providers when implementing single-handed care. The findings have confirmed anecdotal evidence that reviews of double-handed homecare packages are common practice within local authorities. Given the amount of time taken with these reviews, and paucity of evidence on outcomes for people receiving them, further research should evaluate this.

Abstract
Hoarding disorder is characterized by an accumulation of possessions due to excessive acquisition of or difficulty discarding possessions, regardless of their actual value and is estimated to affect 2-6% of the population. Animal hoarding, a distinct subset of hoarding disorder, has a significant public health impact on the humans involved, as well as animal welfare. Individuals exhibit self-neglect, apathy, social withdrawal and object hoarding; living within squalid, deteriorated, structurally unsafe and uninhabitable premises, alongside neglected animals. Cases are complex, costly and impact on a range of responding service providers. Effective case management is poorly understood and researched, with published literature in England particularly sparse. Improving understanding of the characteristics of these cases is the first step in informed case management. This research is the first exploration of the characteristics of animal hoarders in England and the areas where cases were located. Information about prosecutions involving large numbers of animals that were reported in the media was systematically obtained. This identified 66 cases between January 2015 and December 2020. Geospatial analysis exploring characteristics of locations where animal hoarding cases are also reported. Findings were broadly consistent with the international literature in that females (64%), those living alone (71%) and those with a mean age of 49 were well represented. Cats (61.5%) and dogs (60%) were the most commonly hoarded species. There was a mean of 44 animals per case and dead or animals requiring euthanasia found in 53% of cases. Key characteristics of the areas where cases were found highlight urban, densely populated, and high levels of deprivation being the most represented. Evidence of recidivism was evident in 39% of cases, suggesting that prosecution is not an effective rehabilitator. Animal hoarding raises serious implications for Public Health Services, and the lack of current effective case management strategies are discussed.

Abstract
Abstract
Purpose: This study examined the relationship between individual-level experiences of social adversity and baseline computerized concussion testing validity (Immediate Post-Concussion Assessment and Cognitive Testing; ImPACT). Methods: This study involved 6495 student-athletes born between 1995 and 2005 who completed a baseline ImPACT test between 10 and 18 years old and could be identified in the Child-Household Integrated Longitudinal Data (CHILD) System, a continuously updated integrated and comprehensive data system that captures detailed individual-level demographic, social service usage, and educational outcomes on every child born or living in Cuyahoga County, Ohio from 1989 to present. Multivariable logistic regression models were conducted with experiences of SNAP/TANF enrollment, substantiated abuse or neglect incidents, and extreme neighborhood deprivation occurring in the sensitive developmental periods of early childhood and adolescence as key predictors of baseline test validity. Results: Our findings suggest that social mobility may play an important role in baseline validity. Youth with upward social mobility (poverty or neighborhood deprivation in early childhood only) were not significantly different than youth without such experiences (OR = 0.91, p = 0.74). Youth with persistent adversity across childhood or downward social mobility (poverty or high neighborhood deprivation in adolescence only) had 50–72% lower odds of achieving a valid baseline test (persistent poverty: OR = 0.59, p = 0.05; adolescent poverty only: OR = 0.50, p = 0.004; adolescent neighborhood deprivation only: OR = 0.28, p < 0.0001). Conclusions: These findings suggest certain patterns of social adversity may predispose youth to invalid computerized concussion baseline testing scores, potentially increasing their risk of inaccurate injury management and poor outcomes.

Abstract
BACKGROUND Nursing surveillance (NS) involves the purposeful, ongoing acquisition, interpretation, and synthesis of patient data for clinical decision-making. Surveillance is used to identify patients with early signs of distress and prevent adverse events. The processes that support and measure the outcomes of nursing surveillance are not clearly specified. AIM The aim of this systematic review was to describe the impact of NS on respiratory adverse events for adult hospitalized patients. METHODS The PRISMA model guided this systematic search of Academic Search Complete (EBSCOhost), CINAHL Complete (EBSCOhost), Nursing & Allied Health (ProQuest), and PubMed databases for articles published between 1990 and 2019. Search terms included nursing surveillance, data points typically attributed to nursing surveillance, adult hospitalized patients, and adverse respiratory events. The protocol for this review was registered as PROSPERO: CRD42020147557. RESULTS Of the 2907 references screened, 67 full-text articles were reviewed and 10 were eligible for inclusion. Research on nursing surveillance in the presence of respiratory deterioration is limited. Six studies used assessment tools that were generated from early warning scores, and four used research or institutionally designed trigger criteria. Surveillance, like other types of nursing care, was difficult to isolate and measure. Although components of surveillance were described in the selected studies, the nurse's role was not explicitly identified. Further research is required to highlight the role nursing surveillance plays in clinical decision-making to keep patients safe. LINKING EVIDENCE TO ACTION The attributes of NS provide a useful intervention guide for the hospitalized patient at risk of deterioration. Early warning score techniques provide empirical evidence for identifying patients at risk of deterioration. The findings of this study provide evidence of the significance for research focused on the attributes of NS relative to responding to patients at risk of deterioration.

Background/Introduction: Cryoballoon ablation (CBA) is often associated with shorter procedure times along with tradeoffs such as increased fluoroscopy use compared to radiofrequency (RF) ablation of atrial fibrillation (AF), however the impact of mapping technology on these characteristics is not fully understood.
Purpose
To assess the effect of mapping technology on trends in fluoroscopy use and procedure times in AF pulmonary vein isolation (PVI) procedures with an RF or CBA catheter.
Methods
Acute procedure data from 210 de novo AF cases using a 3D mapping system was prospectively collected from 48 centers in eight countries. Choice of technology was left to physician discretion; a PVI only ablation strategy was utilized in all cases. Procedure data such as total procedure and fluoroscopy times from cases using either an RF or CBA catheter with either a grid-style mapping catheter (HD Grid) or circular mapping catheter (CMC) were compared.
Results
Of the 210 cases, RF ablation was used in 103 (49%), and CBA used in 107 (51%). In RF cases, a relatively even split between CMC and HD Grid use was observed (n=46, 45% vs. n=57, 55%), while a CMC was used in 100% of CBA cases (Figure 1). Across all cases, fluoroscopy and procedure times were significantly shorter when HD Grid was used (7.4±26.7 minutes; 108.2±46.3 minutes) compared to a CMC (20.4±17.6 minutes; 133.7±62.7) (p<0.001; p=0.003). A similar trend was also observed in RF cases using HD Grid (7.4±26.7 minutes; 108.2±46.3 minutes) compared to a CMC (17.9±12.3 minutes; 175.1±50.5) (p=0.01; p<0.001). Fluoroscopy times in RF cases with HD Grid (7.4±26.7 minutes) were significantly shorter compared to CBA cases with a CMC (21.5±19.4 minutes) (p<0.001), while procedure times were similar (108.2±46.3 minutes; 116.0±59.2 minutes, p=0.20).
Conclusion(s)
Use of HD Grid resulted in significantly shorter procedure and fluoroscopy times compared to a CMC across all cases, including those using RF ablation. Fluoroscopy times were also significantly shorter in RF cases using HD Grid compared to CBA cases using a CMC, with similar procedure times. These observations suggest that use of HD Grid may better enable safer and more efficient PVI, specifically when employing RF ablation, in addition to safer and equally efficient RF PVI compared to CBA with a CMC. Further study in in a larger, randomized cohort may be necessary.

Background/Introduction
Choice in mapping technology may play a critical role in reducing fluoroscopy and procedure times during atrial fibrillation (AF) ablation, however this relationship is not well studied.
Purpose
To assess the impact of mapping technology on trends in fluoroscopy use and procedure times in AF ablation procedures.
Methods
Acute procedure data from 525 AF cases was prospectively collected from 68 centers in nine countries. Choice of technology and ablation strategy, including PVI and substrate modification, were left to physician discretion. Procedure data such as total procedure and fluoroscopy times from cases using a grid-style mapping catheter (HD Grid) were compared to those using a circular mapping catheter (CMC).
Results
Of the 525 cases, HD Grid was used in 230 (44%), and CMC was used in 295 (56%). HD Grid was routinely used for both de novo and redo procedures while CMC was used predominantly for de novo procedures (Table 1). Similar procedure times were noted in redo PAF and redo PersAF procedures, while significantly shorter procedure times were observed for the HD Grid group in both de novo PAF and PersAF (113.9±48.8 vs. 125.9±56.3 minutes, p=0.04; and 142.8±53.2 vs. 169.8±52.2 minutes, p=0.001).
Overall fluoroscopy times were significantly shorter using HD Grid compared to a CMC (9.0±19.6 minutes vs. 19.8±16.4 minutes, p<0.001), including significantly shorter fluoroscopy times in de novo PAF, de novo PersAF, and redo PAF (Table 1). There were 155 cases completed without fluoroscopy use; zero fluoroscopy cases accounted for 50% (114/230) and 14% (41/295) of total cases completed with HD Grid and a CMC, respectively (p<0.001).
Conclusion(s)
Use of HD Grid was observed in a significantly higher portion of zero fluoroscopy cases and resulted in significantly shorter procedure and fluoroscopy times in both de novo PAF and de novo PersAF and significantly shorter fluoroscopy times in redo PAF. These observations suggest that use of HD Grid may better enable faster and safer procedures in these specific AF types compared to CMCs, although further analysis in a larger, randomized cohort may be warranted.

Background/Introduction
A novel mapping algorithm recently became available in Europe and select countries in the Asia Pacific region. EnSite Omnipolar Technology (OT) utilizes the Advisor HD Grid Mapping Catheter, Sensor Enabled (HD Grid) to calculate electrograms in 360 degrees from two bipolar and three unipolar electrograms acquired from a triangular set of three electrodes. This software also enables calculation of wavefront characteristics including maximum voltage, activation direction and wave speed. Procedural characteristics and clinical utilization of this novel software have not yet been reported.
Purpose
To examine the clinical utility and procedural characteristics associated with the use of this novel mapping algorithm among participating centers.
Methods
Acute procedural data were prospectively collected in 386 cases at 52 centers utilizing the newly approved mapping software in the initial phases of commercialization in Europe and the Asia Pacific region. Procedural characteristics recorded included indication for mapping/ablation, navigation mode, mapping reference, and maps and tools used to diagnose/locate ablation targets.
Results
A total of 14 indications for mapping and ablation were represented including AF, atypical flutter, and VT (Table 1). VoXel (magnetic primary) navigation mode was used in most cases (n=325, 84%). The CS catheter was used as the map reference in 280 cases (73%). A variety of workflows were used with OT to diagnose and locate ablation targets including voltage maps (n=275, 71%), LAT maps (n=226, 59%), OT activation vectors (n=124, 32%), propagation maps (n=94, 24%), and sparkle maps (n=69, 18%); note: total exceeds 100%, multiple workflows per case observed. EnSite LiveView Dynamic Display (LiveView) was used in 129 cases (33%) to diagnose and locate ablation targets, including 28 (22%) where OT activation vectors were used with LiveView. Several benefits of OT were reported including rapid identification of ablation target(s) (n=133, 35%), higher point density (n=82, 21%), better signals (n=69, 18%), and improved procedure efficiency (n=48, 12%).
Conclusion(s)
Initial experience with this novel mapping software in Europe and the Asia-Pacific region illustrated utility in a variety of arrhythmias to diagnose and locate ablation targets. The use of OT provided several benefits including rapid identification of ablation targets and higher point density, however further examination of its impact on procedural efficiencies and acute outcomes is likely warranted.

Abstract
Secondary bacterial infection in COVID-19 patients is associated with increased mortality and disproportionately affects critically ill patients. This single-centre retrospective observational study investigates the comparative efficacy of change in procalcitonin (PCT) and other commonly available biomarkers in revealing or predicting microbiologically proven secondary infection in critical COVID-19 patients. Adult patients admitted to an intensive care unit (ICU) with confirmed SARS-CoV-2 infection between 9 March 2020 and 5 June 2020 were recruited to the study. For daily biomarker and secondary infection, laboratory-confirmed bloodstream infection (LCBI) and ventilator-associated pneumonia/tracheobronchitis (VAP/VAT) data were collected. We observed a PCT rise in 53 (81.5%) of the patients, a C-reactive protein (CRP) rise in 55 (84.6%) and a white blood cell count (WBC) rise in 61 (93.8%). Secondary infection was confirmed in 33 (50.8%) of the patients. A PCT rise was present in 97.0% of patients with at least one confirmed VAP/VAT and/or LCBI event. CRP and WBC rises occurred in 93.9% and 97.0% of patients with confirmed VAP/VAT and/or LCBI, respectively. Logistic regression analysis found that, when including all biomarkers in the same model, there was a significant association between PCT rise and the occurrence of LCBI and/or VAP/VAT (OR = 14.86 95%CI: 2.20, 342.53; p = 0.021). Conversely, no statistically significant relationship was found between either a CRP rise (p = 0.167) or a WBC rise (p = 0.855) and the occurrence of VAP/VAT and/or LCBI. These findings provide a promising insight into the usefulness of PCT measurement in predicting the emergence of secondary bacterial infection in ICU.

Abstract
OBJECTIVE To explore how occupational therapists and physiotherapists constructed and interpreted the meaning of rehabilitation in relation to older people in acute care. DESIGN A focussed ethnographic study was undertaken, primarily using observation, interviewing and review of clinical records within one acute medical ward in a general hospital in the UK. Five patient participants gave consent for their episode of care to be studied, with observations and interviews primarily involving the identified patients and five occupational therapy and physiotherapy professionals. RESULTS Four themes were identified: rehabilitation as a process to facilitate physical improvement; rehabilitation as physiotherapy-led; rehabilitation as a place…but not here; and rehabilitation as a process which prioritises safety over function. Such conceptualisations of rehabilitation were recognised as rooted in social and historical perceptions and challenged the ideals of rehabilitation professionals. CONCLUSIONS The meaning of rehabilitation in acute care is shaped by a range of cultural, contextual and systemic influences. Recognising these influences, and subsequent challenges to rehabilitation ideals, can encourage professionals to work towards meaningful change.Implications for RehabilitationA reductionist version of rehabilitation was evident within this context which placed value on physical improvement, achieving optimum safety and led by physiotherapy.This version of rehabilitation was unsatisfactory to occupational therapists and physiotherapists in this setting and different to their ideals.Where rehabilitation may be associated with another place, practitioners should reflect on whether this is influencing patients becoming a lower priority for interventions whilst waiting and address this, if required, within their own reasoning, prioritisation and delegation.Those who recognise similarities with their own practice context could individually, and within teams, revisit definitions of rehabilitation to notice, document and have conversations about the ideals of their professions versus the reality of practice.Occupational therapists and physiotherapists can be champions for organisational and cultural change to promote rehabilitation as a multi-disciplinary phase of care working towards optimising improvements in wellbeing, function and safety, irrespective of location.

Abstract
BACKGROUND CONTEXT Spine patients have a higher rate of depression then the general population which may be caused in part by levels of pain and disability from their spinal disease. PURPOSE Determination whether improvements in health-related quality of life (HRQOL) resulting from successful spine surgery leads to improvements in mental health. STUDY DESIGN/SETTING The Canadian Spine Outcome Research Network prospective surgical outcome registry. OUTCOME MEASURES Change between preoperative and postoperative SF12 Mental Component Score (MCS). Secondary outcomes include European Quality of Life (EuroQoL) Healthstate, SF-12 Physical Component Score (PCS), Oswestry Disability Index (ODI), Patient Health Questionaire-9 (PHQ9), and pain scales. METHODS The Canadian Spine Outcome Research Network registry was queried for all patients receiving surgery for degenerative thoracolumbar spine disease. Exclusion criteria were trauma, tumor, infection, and previous spine surgery. SF12 Mental Component Scores (MCS) were compared between those with and without significant improvement in postoperative disability (ODI) and secondary measures. Multivariate analysis examined factors predictive of MCS improvement. RESULTS Eighteen hospitals contributed 3222 eligible patients. Worse ODI, EuroQoL, PCS, back pain and leg pain correlated with worse MCS at all time points. Overall, patients had an improvement in MCS that occurred within 3 months of surgery and was still present 24 months after surgery. Patients exceeding Minimally Clinically Important Differences in ODI had the greatest improvements in MCS. Major depression prevalence decreased up to 48% following surgery, depending on spine diagnosis. CONCLUSIONS Large scale, real world, registry data suggests that successful surgery for degenerative lumbar disease is associated with reduction in the prevalence of major depression regardless of the specific underlaying diagnosis. Worse baseline MCS was associated with worse baseline HRQOL and improved postoperatively with coincident improvement in disability, emphasizing that mental wellness is not a static state but may improve with well-planned spine surgery.

Abstract
Introduction Evaluations of rehabilitation potential are an everyday occurrence, yet the concept is poorly understood and there is a lack of understanding about the reasoning process. This study aimed to explore how occupational therapists and physiotherapists evaluated the rehabilitation potential of older people following an acute hospital admission. Method Focused ethnography was utilised, primarily using observation, interviewing and review of records within one acute medical ward in a general hospital in the United Kingdom. Five patient participants gave consent for their episode of care to be studied, for interactions with professionals to be observed and for their clinical records to be reviewed. Three occupational therapists and two physiotherapists then participated in individual interviews. Findings Thematic analysis of data led to the identification of a four-stage reasoning process. The four stages are as follows: gathering baseline information; provision of curative and supportive interventions; provision and monitoring of rehabilitative interventions; the evaluation of rehabilitation potential and decision about the subsequent pathway. Conclusions The reasoning process illustrates the professional reasoning of occupational therapists and physiotherapists when evaluating rehabilitation potential for older adults in acute care. However, it also highlights vulnerabilities to professional reasoning which may contribute to subjectivity, inconsistency or risk to patients.
