Burnout and depression: Points of convergence and divergence. J Affect Disord 2023; 339:561-570. [PMID: 37479038 DOI: 10.1016/j.jad.2023.07.095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 07/13/2023] [Accepted: 07/17/2023] [Indexed: 07/23/2023]
Abstract
BACKGROUND Debate is ongoing as to whether burnout can be differentiated from depression. This study evaluated whether burnout and depression could be distinguished using a new burnout measure and other variables. METHODS Scores on the Sydney Burnout Measure (SBM) were compared between participants with self-diagnosed burnout (BO-all group; n = 622) and clinically-diagnosed depression (DEP-all group; n = 90). The latter group was split into melancholic (DEP-mel; n = 56) and non-melancholic (DEP-nonmel; n = 34) depression subgroups for subsequent analyses. Differences in reporting of depressive symptoms and causal attributions were also evaluated. RESULTS While total SBM scores showed poor differentiation, the BO-all group had lower social withdrawal and higher empathy loss subscale scores than the depression groups. Odds ratios were significant for several of the depressive symptoms and causal attribution items when comparing the BO-all group to the DEP-all and DEP-mel groups, while only a few items were significant when comparing the BO-all and DEP-nonmel groups. LIMITATIONS Participants in the depression group were assigned by clinician-based depression diagnoses, rather than by a standardised diagnostic interview, and the group had a relatively small sample size. Participants in the burnout group were self-diagnosed and not assessed for comorbid psychiatric diagnoses. CONCLUSIONS There were some nuanced symptoms differences between burnout and depression, but many of the SBM symptoms were not specific to burnout. Results also suggested that burnout overlaps more with non-melancholic than melancholic depression, and that differentiation of burnout and depression may rely more on weighting causal factors over symptoms.

Perception of Size and Mass Relationships of Moving and Stationary Object in Collision Events in 10-to-11-Month-Old Infants. Behav Sci (Basel) 2023; 13:bs13010056. [PMID: 36661628 PMCID: PMC9855046 DOI: 10.3390/bs13010056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 12/26/2022] [Accepted: 12/28/2022] [Indexed: 01/11/2023] Open
Abstract
Around 5.5-6.5 months of age, infants first attend to object size and perceive its mass cues in simple collision events. Infants attend to the size of the moving object and expect a greater displacement following a collision with a large object and stationary object, and lesser displacement following a collision with a small object and stationary object. It has been proposed that infants of 6-to-7 months of age can differentiate between sizes of moving objects but do not perceive the size and mass relationships in simple collision events. The present two investigations aimed to investigate whether infants 10-to-11 months of age (N = 16) could perceive this relationship (experiment 1) and the reverse of this relationship (experiment 2) utilising the looking time paradigm. The reverse of this relationship entailed the circumstances in which the moving object size was kept constant, but the stationary object size varied (small or large). Results from these experiments revealed that infants did not differ in their looking times for size congruent and size incongruent distances in both conditions. Infants did not look longer at the incongruent test events that violated expectation. For that reason, we conclude infants of 10-to-11 months of age were unable to perceive size and mass associations in collision events in either direction (moving object or stationary object size).

Considering equity in priority setting using transmission models: Recommendations and data needs. Epidemics 2022; 41:100648. [PMID: 36343495 PMCID: PMC9623400 DOI: 10.1016/j.epidem.2022.100648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 09/20/2022] [Accepted: 10/21/2022] [Indexed: 11/06/2022] Open
Abstract
OBJECTIVES Disease transmission models are used in impact assessment and economic evaluations of infectious disease prevention and treatment strategies, prominently so in the COVID-19 response. These models rarely consider dimensions of equity relating to the differential health burden between individuals and groups. We describe concepts and approaches which are useful when considering equity in the priority setting process, and outline the technical choices concerning model structure, outputs, and data requirements needed to use transmission models in analyses of health equity. METHODS We reviewed the literature on equity concepts and approaches to their application in economic evaluation and undertook a technical consultation on how equity can be incorporated in priority setting for infectious disease control. The technical consultation brought together health economists with an interest in equity-informative economic evaluation, ethicists specialising in public health, mathematical modellers from various disease backgrounds, and representatives of global health funding and technical assistance organisations, to formulate key areas of consensus and recommendations. RESULTS We provide a series of recommendations for applying the Reference Case for Economic Evaluation in Global Health to infectious disease interventions, comprising guidance on 1) the specification of equity concepts; 2) choice of evaluation framework; 3) model structure; and 4) data needs. We present available conceptual and analytical choices, for example how correlation between different equity- and disease-relevant strata should be considered dependent on available data, and outline how assumptions and data limitations can be reported transparently by noting key factors for consideration. CONCLUSIONS Current developments in economic evaluations in global health provide a wide range of methodologies to incorporate equity into economic evaluations. Those employing infectious disease models need to use these frameworks more in priority setting to accurately represent health inequities. We provide guidance on the technical approaches to support this goal and ultimately, to achieve more equitable health policies.

Abstract
Prior to the usual clinical symptoms of dementia, there can be subtle changes in cognitive function that differ from the normal age-related cognitive decline, which has been termed mild cognitive impairment (MCI). The increase in the numbers of individuals with possible MCI presenting to health care professionals, notably, General Practitioners (GPs), is going to rise dramatically in the coming years. With ever increasing demands on GPs, it is therefore timely to provide information that can be accessed by health care professionals to assist them in making appropriate diagnoses and to provide the most relevant, evidence-based treatment options. We have provided a comprehensive list of recommendations that aim to address key aspects of MCI in primary care. Specifically, these relate to detection and diagnosis; sharing the diagnosis, monitoring, and follow up; practical interventions to potentially delay progression; and personalizing care—planning, engagement, and patient motivation for the long term.

Evaluation of maximum dose intravenous midazolam used in dental intravenous sedation: a West of Scotland regional audit. Br Dent J 2022; 233:135-138. [PMID: 35869215 PMCID: PMC9305050 DOI: 10.1038/s41415-022-4456-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 03/07/2022] [Indexed: 11/30/2022]
Abstract
Background Intravenous (IV) midazolam sedation is commonly used in the delivery of dentistry for phobic patients. There is currently no guidance on a maximum dose for use specifically in dentistry. Dentists practise with the British National Formulary recommended maximum dose of 7.5 mg; however, anecdotally, this is often exceeded. We aim to evaluate prescribing and propose recommendations for a maximum dose for dentists. Method Data was collected from ten dentists across four Scottish health boards regarding their last 20 IV sedation patients, giving a total of 200. Data obtained from standard Dental Sedation Teachers Group IV logbooks included: dose of midazolam administered; justification for doses over 7.5 mg; flumazenil or supplemental oxygen usage; significant medical/social factors; and the Ramsay Sedation Score. Results Mean midazolam dose was 6.1 mg with a range of 14 mg. The recommended maximum dose of 7.5 mg was exceeded in 28% of cases. The mean sedation score was 2.7 and there were no reported adverse events or use of flumazenil. Conclusion IV midazolam is an effective way to achieve conscious sedation in dentistry. Acknowledgement of current off-label prescribing is important; however, 7.5 mg as a recommended maximum dose is too conservative as it is regularly exceeded without adverse events. Further investigation and expert opinion is required to set a maximum dose specifically for dentistry. British National Formulary's intravenous midazolam recommended maximum dose of 7.5 mg was exceeded without adverse events in 28% of cases. Intravenous midazolam doses over 7.5 mg are considered 'off-label' but are accepted as 'common practice' in dental conscious sedation where a single drug technique (midazolam) is used. This study demonstrates intravenous midazolam doses from 1-15 mg were administered without adverse events.

Elevations in Tumor Necrosis Factor Alpha and Interleukin 6 From Neuronal-Derived Extracellular Vesicles in Repeated Low-Level Blast Exposed Personnel. Front Neurol 2022; 13:723923.

Abstract
Objective The purpose of this pilot study was to determine if military service members with histories of hundreds to thousands of low-level blast exposures (i. e., experienced breachers) had different levels of serum and neuronal-derived extracellular vesicle (EV) concentrations of interleukin (IL)-6, IL-10, and tumor necrosis factor alpha (TNFα), compared to matched controls, and if these biomarkers related to neurobehavioral symptoms. Methods Participants were experienced breachers (n = 20) and matched controls without blast exposures (n = 14). Neuronal-derived EVs were isolated from serum and identified with mouse anti-human CD171. Serum and neuronal-derived EVs were analyzed for IL-6, IL-10, and TNFα using an ultra-sensitive assay. Results Serum TNFα concentrations were decreased in breachers when compared to control concentrations (p < 0.01). There were no differences in serum concentrations of IL-6, IL-10, or the IL-6/IL-10 ratio between breachers and controls (p's > 0.01). In neuronal-derived EVs, TNFα and IL-6 levels were increased in breachers compared to controls (p's < 0.01), and IL-10 levels were decreased in the breacher group compared to controls (p < 0.01). In breachers the IL-6/IL-10 ratio in neuronal-derived EVs was higher compared to controls, which correlated with higher total Rivermead Post-concussion Questionnaire (RPQ) scores (p's < 0.05). Conclusions These findings suggest that exposure of personnel to high numbers of low-level blast over a career may result in enduring central inflammation that is associated with chronic neurological symptoms. The data also suggest that peripheral markers of inflammation are not necessarily adequate surrogates for central neuroinflammation.

Abstract
BACKGROUND The demand for total hip replacement (THR) for treating osteoarthritis has grown substantially worldwide. The existing robotic systems used in THR are invasive and costly. This study aims to develop a less-invasive and low-cost robotic system to assist THR surgery. METHODS A preliminary robotic reaming system was developed based on a UR10 robot equipped with a reamer to cut acetabulum. A novel approach was proposed to cut through a 5 mm hole in femur such that the operation is less invasive to the patients. RESULTS The average error of the cutting hemisphere by the robotic reaming system is 0.1182 mm which is smaller than the average result reaming by hand (0.1301 mm). CONCLUSION The robotic reaming can help make THR procedures less invasive and more accurate. Moreover, the system is expected to be significantly less expensive than the robotic systems available in the market at present.

Abstract
Military and law enforcement breachers are exposed to many low-level blasts during their training and occupational experiences in which they detonate explosives to force entry into secured structures. There is a concern that exposure to these repetitive blast events in career breachers could result in cumulative neurological effects. This study aimed to determine concentrations of neurofilament light (NF-L), tau, and amyloid-beta 42 (Aβ42) in serum and in neuronal-derived extracellular vesicles (EVs) in an experienced breacher population, and to examine biomarker associations with neurobehavioral symptoms. Thirty-four participants enrolled in the study: 20 experienced breachers and 14 matched military or civilian law enforcement controls. EV tau concentrations were significantly elevated in experienced breachers (0.3301 ± 0.5225) compared to controls (-0.4279 ± 0.7557; F = 10.43, p = 0.003). No statistically significant changes were observed in EV levels of NF-L or Aβ42 or in serum levels of NF-L, tau, or Aβ42 (p's > 0.05). Elevated EV tau concentrations correlated with increased Neurobehavioral Symptom Inventory (NSI) score in experienced breachers (r = 0.596, p = 0.015) and predicted higher NSI score (F(1,14) = 7.702, p = 0.015, R2 = 0.355). These findings show that neuronal-derived EV concentrations of tau are significantly elevated and associated with neurobehavioral symptoms in this sample of experienced breachers who have a history of many low-level blast exposures.

Abstract
Background By 2030, the global population of people older than 60 years is expected to be higher than the number of children under 10 years, resulting in major health and social care system implications worldwide. Without a supportive environment, whether social or built, diminished functional ability may arise in older people. Functional ability comprises an individual's intrinsic capacity and people's interaction with their environment enabling them to be and do what they value. Objectives This evidence and gap map aims to identify primary studies and systematic reviews of health and social support services as well as assistive devices designed to support functional ability among older adults living at home or in other places of residence. Search Methods We systematically searched from inception to August 2018 in: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, CENTRAL, CINAHL, PsycINFO, AgeLine, Campbell Library, ASSIA, Social Science Citation Index and Social Policy & Practice. We conducted a focused search for grey literature and protocols of studies (e.g., ProQuest Theses and Dissertation Global, conference abstract databases, Help Age, PROSPERO, Cochrane and Campbell libraries and ClinicalTrials.gov). Selection Criteria Screening and data extraction were performed independently in duplicate according to our intervention and outcome framework. We included completed and on-going systematic reviews and randomized controlled trials of effectiveness on health and social support services provided at home, assistive products and technology for personal indoor and outdoor mobility and transportation as well as design, construction and building products and technology of buildings for private use such as wheelchairs, and ramps. Data Collection and Analysis We coded interventions and outcomes, and the number of studies that assessed health inequities across equity factors. We mapped outcomes based on the International Classification of Function, Disability and Health (ICF) adapted categories: intrinsic capacities (body function and structures) and functional abilities (activities). We assessed methodological quality of systematic reviews using the AMSTAR II checklist. Main Results After de-duplication, 10,783 records were screened. The map includes 548 studies (120 systematic reviews and 428 randomized controlled trials). Interventions and outcomes were classified using domains from the International Classification of Function, Disability and Health (ICF) framework. Most systematic reviews (n = 71, 59%) were rated low or critically low for methodological quality.The most common interventions were home-based rehabilitation for older adults (n = 276) and home-based health services for disease prevention (n = 233), mostly delivered by visiting healthcare professionals (n = 474). There was a relative paucity of studies on personal mobility, building adaptations, family support, personal support and befriending or friendly visits. The most measured intrinsic capacity domains were mental function (n = 269) and neuromusculoskeletal function (n = 164). The most measured outcomes for functional ability were basic needs (n = 277) and mobility (n = 160). There were few studies which evaluated outcome domains of social participation, financial security, ability to maintain relationships and communication.There was a lack of studies in low- and middle-income countries (LMICs) and a gap in the assessment of health equity issues. Authors' Conclusions There is substantial evidence for interventions to promote functional ability in older adults at home including mostly home-based rehabilitation for older adults and home-based health services for disease prevention. Remotely delivered home-based services are of greater importance to policy-makers and practitioners in the context of the COVID-19 pandemic. This map of studies published prior to the pandemic provides an initial resource to identify relevant home-based services which may be of interest for policy-makers and practitioners, such as home-based rehabilitation and social support, although these interventions would likely require further adaptation for online delivery during the COVID-19 pandemic. There is a need to strengthen assessment of social support and mobility interventions and outcomes related to making decisions, building relationships, financial security, and communication in future studies. More studies are needed to assess LMIC contexts and health equity issues.

Abstract
OBJECTIVE The objective of this study was to determine the interaction between psychological factors, belief systems, and engagement around public health initiatives. STUDY DESIGN We conducted a longitudinal observational study, utilising convenience sampling to examine illness-related perception in the immediate and medium-term stages of the first wave of the SARS-CoV-2 pandemic in the UK. METHODS Weekly questionnaires assessed our primary measure, illness-related perception, using The Health Anxiety Inventory. Other psychological measures included apathy, loneliness, depersonalisation, state anxiety, trait anxiety as well as personality traits. Multiple regressions were performed to determine which psychological factors predicted the variance of health anxiety every week using the enter method. RESULTS A combination of psychological variables that varied over time and were modulated by external events predicted the evolution of illness-related perception and associated aversion to perceived threat. CONCLUSION Our findings highlight how in the face of a public health crisis, psychological factors play a determining role in the synthesis of beliefs as well as guiding human behaviour.

Abstract
With the rapid development of computer software and hardware technologies, more and more healthcare data are becoming readily available from clinical institutions, patients, insurance companies, and pharmaceutical industries, among others. This access provides an unprecedented opportunity for data science technologies to derive data-driven insights and improve the quality of care delivery. Healthcare data, however, are usually fragmented and private making it difficult to generate robust results across populations. For example, different hospitals own the electronic health records (EHR) of different patient populations and these records are difficult to share across hospitals because of their sensitive nature. This creates a big barrier for developing effective analytical approaches that are generalizable, which need diverse, “big data.” Federated learning, a mechanism of training a shared global model with a central server while keeping all the sensitive data in local institutions where the data belong, provides great promise to connect the fragmented healthcare data sources with privacy-preservation. The goal of this survey is to provide a review for federated learning technologies, particularly within the biomedical space. In particular, we summarize the general solutions to the statistical challenges, system challenges, and privacy issues in federated learning, and point out the implications and potentials in healthcare.

Abstract
Combat military and civilian law enforcement personnel may be exposed to repetitive low-intensity blast events during training and operations. Persons who use explosives to gain entry (i.e., breach) into buildings are known as “breachers” or dynamic entry personnel. Breachers operate under the guidance of established safety protocols, but despite these precautions, breachers who are exposed to low-level blast throughout their careers frequently report performance deficits and symptoms to healthcare providers. Although little is known about the etiology linking blast exposure to clinical symptoms in humans, animal studies demonstrate network-level changes in brain function, alterations in brain morphology, vascular and inflammatory changes, hearing loss, and even alterations in gene expression after repeated blast exposure. To explore whether similar effects occur in humans, we collected a comprehensive data battery from 20 experienced breachers exposed to blast throughout their careers and 14 military and law enforcement controls. This battery included neuropsychological assessments, blood biomarkers, and magnetic resonance imaging measures, including cortical thickness, diffusion tensor imaging of white matter, functional connectivity, and perfusion. To better understand the relationship between repetitive low-level blast exposure and behavioral and imaging differences in humans, we analyzed the data using similarity-driven multi-view linear reconstruction (SiMLR). SiMLR is specifically designed for multiple modality statistical integration using dimensionality-reduction techniques for studies with high-dimensional, yet sparse, data (i.e., low number of subjects and many data per subject). We identify significant group effects in these data spanning brain structure, function, and blood biomarkers.

Abstract
Liver transplantation continues to rise in frequency, with over 1,000 procedures performed in the UK in 2018. Complications are increasingly uncommon but when they occur, early recognition and intervention is vital to save grafts. Imaging after the perioperative period is often performed at patients' local hospitals meaning that all radiologists and sonographers need to have an understanding of how to assess a transplant liver. Part I of this series will focus on vascular complications, including the normal postoperative vascular anatomy following liver transplantation, normal post-transplantation vascular imaging findings and abnormal findings that may prompt further investigation. Vascular complications following liver transplantation will be illustrated using a collection of cases.

Risk factors for excessive tidal volumes delivered during intraoperative mechanical ventilation, a retrospective study. INTERNATIONAL JOURNAL OF PHYSIOLOGY, PATHOPHYSIOLOGY AND PHARMACOLOGY 2020; 12:51-57. [PMID: 32419900 PMCID: PMC7218738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Accepted: 03/26/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Lung Protective Ventilation (LPV) refers to a combination of measures aimed at reducing ventilator-associated lung injury. This includes: delivering tidal volumes of 6-8 ml/kg of ideal body weight, use of positive end expiratory pressure and recruitment maneuvers. With Postoperative Pulmonary Complications (PPCs) contributing towards significant morbidity and mortality following surgery, evidence indicates that effective use of LPV measures intraoperatively has been associated with reduced rates of PPCs. METHODS We conducted a post-hoc analysis using data from a recent clinical audit on departmental ventilation practices. Potential risk factors for excessive tidal volume ventilation were assessed using univariable and multivariable regression models. RESULTS Obesity and gender are independently associated with risk of excessive ventilation. In contrast, the urgency and length of surgery, the choice of airway devices and the mode of ventilation were not associated with excessive ventilation. CONCLUSION There is an association between female gender, obesity and excessive tidal volume ventilation. This may be addressed through formal, protocolized intraoperative ventilation setting.

Abstract
Blast exposure is common in military personnel during training and combat operations, yet biological mechanisms related to cell survival and function that coordinate recovery remain poorly understood. This study explored how moderate blast exposure influences gene expression; specifically, gene-network changes following moderate blast exposure. On day 1 (baseline) of a 10-day military training program, blood samples were drawn, and health and demographic information collected. Helmets equipped with bilateral sensors worn throughout training measured overpressure in pounds per square inch (psi). On day 7, some participants experienced moderate blast exposure (peak pressure ≥5 psi). On day 10, 3 days post-exposure, blood was collected and compared to baseline with RNA-sequencing to establish gene expression changes. Based on dysregulation data from RNA-sequencing, followed by top gene networks identified with Ingenuity Pathway Analysis, a subset of genes was validated (NanoString). Five gene networks were dysregulated; specifically, two highly significant networks: (1) Cell Death and Survival (score: 42), including 70 genes, with 50 downregulated and (2) Cell Structure, Function, and Metabolism (score: 41), including 69 genes, with 41 downregulated. Genes related to ubiquitination, including neuronal development and repair: UPF1, RNA Helicase and ATPase (UPF1) was upregulated while UPF3 Regulator of Nonsense Transcripts Homolog B (UPF3B) was downregulated. Genes related to inflammation were upregulated, including AKT serine/threonine kinase 1 (AKT1), a gene coordinating cellular recovery following TBIs. Moderate blast exposure induced significant gene expression changes including gene networks involved in (1) cell death and survival and (2) cellular development and function. The present findings may have implications for understanding blast exposure pathology and subsequent recovery efforts.

Abstract
Background Juxtarenal abdominal aortic aneurysms pose a significant challenge whether managed endovascularly or by open surgery. Fenestrated endovascular aneurysm repair (FEVAR) is now well established, but few studies have compared it with open surgical repair (OSR). The aim of this systematic review was to compare short‐ and long‐term outcomes of FEVAR and OSR for the management of juxtarenal aortic aneurysms. Methods A literature search was conducted of the Ovid Medline, EMBASE and PubMed databases. Reasons for exclusion were series with fewer than 20 patients, studies published before 2007 and those concerning ruptured aneurysms. Owing to variance in definitions, the terms ‘juxta/para/suprarenal’ were used; thoracoabdominal aortic aneurysms were excluded. Primary outcomes were 30‐day/in‐hospital mortality and renal insufficiency. Secondary outcomes included major complication rates, rate of reintervention and rates of endoleak. Results Twenty‐seven studies were identified, involving 2974 patients. Study designs included 11 case series, 14 series within retrospective cohort studies, one case–control study and a single prospective non‐randomized trial. The pooled early postoperative mortality rate following FEVAR was 3·3 (95 per cent c.i. 2·0 to 5·0) per cent, compared with 4·2 (2·9 to 5·7) per cent after OSR. After FEVAR, the rate of postoperative renal insufficiency was 16·2 (10·4 to 23·0) per cent, compared with 23·8 (15·2 to 33·6) per cent after OSR. The major early complication rate following FEVAR was 23·1 (16·8 to 30·1) per cent versus 43·5 (34·4 to 52·8) per cent after OSR. The rate of late reintervention after FEVAR was higher than that after OSR: 11·1 (6·7 to 16·4) versus 2·0 (0·6 to 4·3) per cent respectively. Conclusion No significant difference was noted in 30‐day mortality; however, FEVAR was associated with significantly lower morbidity than OSR. Long‐term durability is a concern, with far higher reintervention rates after FEVAR.

Abstract
A 12-month-old child with a history of prematurity, severe respiratory compromise and failure to thrive required laser supraglottoplasty for severe laryngotracheobronchomalacia. Maintaining adequate oxygenation intraoperatively proved very difficult. Our usual technique with no endotracheal tube was not possible and CO 2 lasering was commenced with a polyvinylchloride endotracheal tube in the operative field. The endotracheal tube was struck by the laser but did not ignite. Concern about the very serious morbidity from a laser-induced fire in the airway prompted a search for possible solutions. No commercially available laser-resistant tube is available in small enough diameter to use in an infant. An aluminium foil tape (3M #425) was evaluated and found to be potentially very useful to protect against an airway fire in this uncommon situation.

Abstract
During the period 1997 to 2002, 42 children were electively admitted to the Paediatric Intensive Care Unit at the John Hunter Children's Hospital following adenotonsillectomy for severe obstructive sleep apnoea. Forty children had a preoperative sleep study, of which 33 were complete polysomnograms. Of the 42 children admitted, 35 required no intervention while seven (17%) required an additional intervention beyond supplemental oxygen. Our criteria for elective admission to Paediatric Intensive Care following adenotonsillectomy for severe obstructive sleep apnoea are presented.

Abstract
Surgical correction of multiapical deformities of the lower limb requires careful preoperative planning. Surgeons must account for the potential creation of secondary deformity, such as knee joint line obliquity, and the risks associated with accepting these changes in limb alignment. In this study, we evaluate the effect of knee joint obliquity on tibial plateau contact pressures and knee instability. Three cadaveric knees were dissected and put through biomechanical testing to simulate loading of an oblique knee joint. We observed < 1 mm femoral displacement (proxy measure of instability) between 15 degrees of varus tilt and 10 degrees of valgus tilt, and greater increases in tibial plateau contact pressures with valgus tilt than with varus tilt. Our results suggest that, if the creation of a secondary coronal plane deformity at the knee joint cannot be avoided, up to 15 degrees of varus or 10 degrees of valgus alignment can be tolerated by an otherwise structurally normal knee.

Abstract
Adult obesity in the UK remains a public health priority. Current guidance recommends local areas provide multicomponent interventions to treat adults with overweight and obesity; however, there is currently a dearth of published evidence on the evaluation of these programmes. This study reports on a mixed method evaluation of seven tier 2 weight management programmes funded by a local authority in the North of England through their public health grant (a lifestyle multicomponent weight management programme for the treatment of adults with overweight and obesity, but not severe obesity, or obesity with severe co-morbidities). Data collected from over 2000 participants demonstrated that the proportion of participants achieving 5% initial body weight loss was comparable to that reported in recent UK weight management trials. Two services exceeded national criteria of 30% of participants achieving 5% initial body weight loss at 12 weeks, although long term data was limited. Greater weight loss was also observed in participants aged 35-44 and those without co-morbidities. This study provides important learning points for improvements in real world weight management services, these include: standardised data collection and management tools; staff training and communication requirements; the importance of programmes that are joined up to wider support services; and the importance of providing ongoing peer and provider support, continuous monitoring and feedback, and physical activities tailored to user needs.

Cross-sensory correspondences in language: Vowel sounds can symbolize the felt heaviness of objects. J Exp Psychol Learn Mem Cogn 2018; 45:246-252.

Abstract
In sound symbolism, a word's sound induces expectations about the nature of a salient aspect of the word's referent. P. Walker (2016a) proposed that cross-sensory correspondences can be the source of these expectations, and the present study assessed three implications flowing from this proposal. First, sound symbolism will embrace a wide range of referent features, including heaviness. Second, any feature of a word's sound able to symbolize one aspect of the word's referent will also be able to symbolize corresponding aspects of the referent (e.g., a sound feature symbolizing visual pointiness will also symbolize lightness in weight). Third, sound symbolism will be independent of the sensory modality through which a word's referent is encoded (e.g., whether heaviness is felt or seen). Adults judged which of two contrasting novel words was most appropriate as a name for the heavier or lighter of two otherwise identical hidden novel objects they were holding in their hands. The alternative words contrasted in their vowels and/or consonants, one or both of which were known to symbolize visual pointiness. Although the plosive or continuant nature of the consonants did not influence the judged appropriateness of a word to symbolize the heaviness of its referent, back/open vowels, compared to front/close vowels, were judged to symbolize felt heaviness. The symbolic potential of back/open vowels to represent felt heaviness, predicted on the basis of their symbolism of visual roundedness, supports the proposal that cross-sensory correspondences contribute to sound symbolism.

Abstract
An investigation was performed to demonstrate that time-lapse cinematography and computer aided video analysis of cell morphology is suitable to study and compare the characteristics of hepatocytes during the adhesion process to membranes. We chose to compare ordinary cellulose Cuprophan membranes and membranes coated with collagen or fibronectin. Striking differences between uncoated cellulose and fibronectin or collagen coating were seen in the cell count per square millimeter and adhesion behaviour. On the investigated uncoated Cuprophan the hepatocytes were found to attach but not to spread whilst on collagen coated Cuprophan most of the cells spread spherically, and on fibronectin coated membranes most of the cells flattened spherically or polygonally. Time-lapse video microscopy seems to be a valuable technique for assessing the morphologic behaviour of cells in a detailed and quantitative manner in order to improve the hepatocyte culture technique in bioreactors for hybrid systems.

Abstract
Aims and MethodThere are no data or guidelines on who should be referred to community mental health teams (CMHTs), resulting in enormous variability in referral patterns. General practitioners (GPs) and psychiatrists were surveyed using a purpose-designed questionnaire to assess their attitudes regarding referral of individuals with different psychiatric disorders.ResultsThere was consensus among GPs and psychiatrists that individuals with psychotic disorders, mania, severe depression and phobias should be referred to CMHTs. GPs were more likely to refer personality disorder, whereas the reverse was true for moderate depression and anxiety/ panic disorders. There was disagreement within groups about referral for acute stress reaction, mild depression and adjustment disorders.Clinical ImplicationsUncertainty about appropriate referral causes variability in referral patterns and service provisions. This needs resolution through the Royal Colleges of Psychiatrists and General Practitioners, to provide guidance leading to equality of care for all.

Abstract
A word printed in lower-case letters has a characteristic shape as a result of the pattern created by its ascending, descending and neutral letters. The importance of word shape as a cue in word recognition, though debated for many years, has still to be satisfactorily resolved. On the assumption that the utility of a word's shape will depend on the extent to which it precludes all but a relative small set of candidate words, a promising approach to the issue compares reading performance for words with rare versus common shapes. As a prerequisite to this experimental approach, however, the distinctiveness of different word shapes needs to be determined. To this end, all of the three- to seven-letter words from the Kučera and Francis (1967) corpus were analysed. This revealed that although word shape in itself is rarely adequate to uniquely identify a word, when it is combined with knowledge of other orthographic features its potential utility is enhanced considerably. Examination of the distribution of letter types across letter positions within words revealed a potential source of information concerning word boundaries. It is suggested that this information may contribute to reading when, for example, the interword spacing is tight. The association of word-shape distinctiveness with a number of other word features is also reported.
