Abstract
BACKGROUND Sleep disturbance is a common symptom of depression. There is conflicting evidence whether improvements in sleep might impact depressive symptoms, or whether treating the core depressive symptoms might improve sleep disturbance. This study explored the bi-directional impact of sleep and depressive symptom change among individuals receiving psychological treatment. METHODS Session-by-session change in sleep disturbance and depressive symptom severity scores were explored in patients receiving psychological therapy for depression from Improving Access to Psychological Therapies services in England. Bi-directional change in sleep disturbance and depressive symptoms was modelled using random-intercept cross-lagged panel models with items from the PHQ-9. RESULTS The sample included 17,732 adults that had received three or more treatment sessions. Both depressive symptoms and sleep disturbance scores decreased. Between initial timepoints, higher sleep disturbance was associated with lower depression scores, but after this point positive cross-lagged effects were observed for both the impact of sleep disturbance on later depressive symptoms, and depressive symptoms on later sleep disturbance scores. The magnitude of effects suggested depressive symptoms may have more impact on sleep than the reverse, and this effect was larger in sensitivity analyses. CONCLUSIONS Findings provide evidence that psychological therapy for depression results in improvements in core depressive symptoms and sleep disturbance. There was some evidence that depressive symptoms may have more impact on sleep disturbance scores at the next therapy session, than sleep disturbance does on later depressive symptoms. Targeting the core symptoms of depression initially may optimise outcomes, but further research is needed to elucidate these relationships.

Abstract
A neonatal intensive care unit (NICU) can be an extremely stressful environment for infants receiving complex medical care at a pediatric facility. Music therapy can help address the stressful environment by increasing comfort and relaxation as well as decreasing a patient's physiological response of heart rate and respiratory rate. A randomized controlled trial was completed, examining the effects of 2 guitar accompaniment patterns on infants (an arpeggiated pattern and a bass/chord pattern) in a NICU. There were 180 infants enrolled with mean chronological ages of 7.4 ± 6.1 weeks and postmenstrual ages (gestational age at birth + their chronological age) of 39.8 ± 7.9 weeks. All subject enrollees participated in a 12-minute initial music therapy session. Outcome measures included heart rate, respirations, and comfort responses. The results of the research study demonstrated that the arpeggiated guitar pattern had a lower mean heart rate and respiratory across all 3 data points (pre, during, and post intervention); however, the difference in means between the 2 accompaniment pattern groups was not statistically significant. Using the Neonatal Infant Pain Scale (NIPS) to measure comfort response, the results demonstrated no difference between the 2 group accompaniment patterns. Although the results show no significant differences among accompaniment pattern groups, the researchers describe the clinical significance that supports the use of both accompaniment patterns as suitable interventions for infants in the NICU receiving music therapy intervention.

Abstract
The Coronavirus (Covid-19) pandemic is exerting unprecedented pressure on NHS Health and Social Care provisions, with frontline staff, such as those of critical care units, encountering vast practical and emotional challenges on a daily basis. Although staff are being supported through organisational provisions, facilitated by those in leadership roles, the emergence of mental health difficulties or the exacerbation of existing ones amongst these members of staff is a cause for concern. Acknowledging this, academics and healthcare professionals alike are calling for psychological support for frontline staff, which not only addresses distress during the initial phases of the outbreak but also over the months, if not years, that follow. Fortunately, mental health services and psychology professional bodies across the United Kingdom have issued guidance to meet these needs. An attempt has been made to translate these sets of guidance into clinical provisions via the recently established Homerton Covid Psychological Support (HCPS) pathway delivered by Talk Changes (Hackney & City IAPT). This article describes the phased, stepped-care and evidence-based approach that has been adopted by the service to support local frontline NHS staff. We wish to share our service design and pathway of care with other Improving Access to Psychological Therapies (IAPT) services who may also seek to support hospital frontline staff within their associated NHS Trusts and in doing so, lay the foundations of a coordinated response. KEY LEARNING AIMS (1)To understand the ways staff can be psychologically and emotionally impacted by working on the frontline of disease outbreaks.(2)To understand the ways in which IAPT services have previously supported populations exposed to crises.(3)To learn ways of delivering psychological support and interventions during a pandemic context based on existing guidance and research.

Abstract
Abstract
Introduction
Aortic valve (AV) stenosis is the most common type of congenital left ventricular outflow tract obstruction. Short-term outcomes following balloon aortic valvuloplasty (BAV) including residual aortic stenosis, aortic insufficiency, and procedural complications have been established. The impact of pre-intervention AV characteristics on long-term outcomes has not been well studied.
Purpose
The aim of this study was to determine the relationship between the initial parameters on baseline echocardiogram and the time to reintervention in children with AV stenosis following BAV.
Methods
Children from the newborn period to 18 years of age with AV stenosis who underwent BAV from 2004-2012 were included. Patients with aortic insufficiency prior to BAV, complex congenital heart lesions, or less than two accessible follow-up echocardiograms were excluded. Baseline and serial echocardiographic data pertaining to aortic valve and LV size and function was retrospectively collected until December 2017 or until the first reintervention. Time to reintervention or death was evaluated.
Results
Among the 98 enrolled patients, the median [IQR] age at BAV was 2.8 months [0.2-75]. The median [IQR] duration of follow-up was 6.8 [1.9-9.0] years. Eighty-nine (83%) patients had bicuspid valve morphology and the median [IQR] peak-to-peak catheterization gradient prior to BAV was 49 [34-65] mmHg. The cumulative proportion [95% CI] of reintervention at 5 years following BAV was 33.7% [23.6%, 42.4%]. Primary indications for reintervention were aortic stenosis (57%), aortic insufficiency (14%), or mixed valve disease (30%). Reinterventions included repeat BAV (49%), AV repair (15%), and AV replacement (36%). Increased LVEF at baseline as well as increased mean LV circumferential strain at baseline were associated with decreased risk of reintervention (HR [95% CI] (1 unit increments): 0.974 [0.959-0.989], p < 0.001; 0.939 [0.884-0.997], p = 0.041 respectively). Increased AV annulus z-score was also associated with decreased risk of reintervention (HR [95% CI] (1 unit increments): 0.806 [0.698-0.93], p = 0.003).
Conclusions
Our results demonstrate that better left ventricular function at baseline, measured by LVEF and mean LV circumferential strain, is associated with a decreased risk of reintervention in neonates and children following BAV. We have also shown that a bigger AV annulus prior to BAV is associated with a decreased risk of reintervention.

Abstract
BACKGROUND AND OBJECTIVES Depression is the second leading cause of disability, worldwide, and increasing access to its effective/preferred treatment requires more attention. Behavioural activation and time-intensive treatment delivery both show promise in this regard, yet research into their combination is limited. This study aimed to investigate the feasibility, effectiveness, and acceptability of time-intensive behavioural activation (BA) for depression METHODS: Eight adults with major depressive disorder were recruited from three outpatient IAPT services in London. The study employed a single case experimental design with multiple baselines. All participants completed time-intensive BA, consisting of up to seven twice weekly sessions with daily prompting in-between and three optional booster sessions. Idiographic, standardised and process measures of depression symptomatology were collected. RESULTS Treatment recruitment and retention indicated that the intervention was feasible. Visual and statistical analyses showed that relative to baseline, 6 out of 8 participants made significant improvements in all idiographic symptoms of depression following the intervention. According to standardised measures of depression, four out of eight participants were considered treatment responders. Five participants completed follow-up measures and the majority of progress was maintained after the withdrawal of the intervention. The intervention was also considered highly acceptable by participants and therapists. LIMITATIONS Conclusions cannot be drawn about the generalizability or the long-term durability of the findings CONCLUSIONS: Overall this study provides new, but tentative evidence highlighting the potential of time-intensive BA as a feasible, effective and acceptable treatment for some adult outpatients with depression. The findings now warrant further, more rigorous evaluation of the treatment.

Abstract
SETTING Nine university-affiliated chest clinics in Australia. OBJECTIVE To evaluate the sensitivity of a whole blood human gamma-interferon assay (HGIA, QuantiFERON-TB) for specific T lymphocyte responses and Tuberculin skin testing (TST) for the detection of Mycobacterium tuberculosis infection in subjects with culture-proven M. tuberculosis disease (TBCP). DESIGN Prospective testing of 129 patients with recent TBCP and 100 patients with non-tuberculosis lung disease (NTBLD). RESULTS Using a defined level of specific IFN-gamma production and TST 10mm as positive cut-offs, the sensitivity of HGIA was 81% compared to 89% for TST (p=0.06). When positive responses in both TST and HGIA were combined, 96% of TB patients were detected. For the NTBLD group, 43% of whom were born overseas, 73% were negative for both the HGIA and TST. Prior immunization with M. bovis (bacille Calmette-Guerin) (BCG) or the type of TB had no effect on the sensitivities of the assays. For those treated for <2 months, the sensitivities for both assays were 84%, but for those treated for >2 months the sensitivity of TST (90%) tended to be higher than for HGIA (81%) (p=0.07). The distribution of TST results in TB patients showed a broad peak between 10 and 25 mm, while the results in the HGIA were bimodal in both TB and NTBLD patients. CONCLUSION HGIA may prove an alternative to skin testing for detecting M. tuberculosis infection in certain settings.

Abstract
PURPOSE Mouthguards worn during sporting competition may influence oral airway flow dynamics and potentially increase airflow resistance during mouth breathing. METHODS We measured oral airflow resistance (RO) in 10 normal subjects (four men, six women, age 29 +/- 3 yr, mean +/- SEM) wearing two different custom-made maxillary mouthguards. RESULTS During tidal mouthpiece breathing (jaw position controlled), inspiratory R(O) (at (1.4 L x s(-1)) increased from 0.22 (0.15-0.46) cm H2O x L(-1) x s(-1) (median and interquartile range) to 0.47 (0.24-0.52) cm H2O x L(-1) x s(-1) with mouthguard 1 (general sports mouthguard) and from 0.34 (0.27-0.51) to 0.46 (0.39-0.86) cm H2O x L(-1) x s(-1) (N = 8) with mouthguard 2 (laminated, field hockey mouthguard, both P < 0.05). With oral only mask breathing (jaw position not controlled), inspiratory R(O) (at 0.4 L x s(-1)) increased to 1.02 (0.42-1.57) cm H2O x L(-1) x s(-1) (P < 0.03, compared with mouthpiece) but was variably affected by both mouthguards. At 1.0 L x s(-1), there was a tendency for both mouthguards to increase inspiratory R(O); however, this effect only reached significance for mouthguard 1 during mouthpiece breathing. CONCLUSION Thus, although maxillary mouthguards do increase R(O) when jaw position is controlled, individual subjects respond differently when in control of mouth opening. This may be related to variable recruitment of compensatory mechanisms (e.g. mouth opening and/or oral airway dilator muscle activity).

Abstract
A nurse-led scheme to prevent hospital admissions by providing emergency services in the community for up to 72 hours cared for 155 people in its first six months. The scheme operated well below full capacity partly because of initial opposition from GPs. The mean age of service users was 79 and the main reasons for referral were chest infections, pneumonia and the need for support following an injury. More than three quarters of those cared for were fit to be discharged from the scheme within 72 hours.

Abstract
This case study presents a 37 year old man, P.P., who shows evidence of both profound executive impairment and diencephalic amnesia associated with two discrete lesion sites following a Sub Arachnoid Haemorrhage. The executive impairment is unusual in type and severity, amounting to a gross impairment in the initiation and organisation of action. The thalamic lesion provides a rare example of diencephalic damage resulting in an extensive retrograde amnesia of the type that is often associated with Korsakoff's syndrome, but which in this case is not associated with prolonged alcohol abuse. Some of the problems caused by the co-occurrence of two such profound and disabling impairments are discussed.

Abstract
We studied the effects of increasing respiratory drive on electromyographic (EMG) soft palate muscle (SPM) activity in nine anesthetized tracheostomy-breathing dogs during hypoxic hypercapnia (HH) with a 14% O2-8% CO2-78% N2 inspired gas mixture. Moving time average EMG activity was recorded from palatinus (PAL), levator veli palatini (LP), and tensor veli palatini (TP) muscles (with bipolar fine-wire electrodes) and diaphragm (DIA; with bipolar hook electrodes). During HH, peak inspiratory DIA activity increased from 18.8 +/- 1.3 to 30.1 +/- 2.0 arbitrary units and minute ventilation increased from 6.2 +/- 0.3 to 18.3 +/- 1.8 l/min (both P < 0.001). Phasic inspiratory, expiratory, and/or tonic EMG activity was present in each SPM during room air breathing (control) and increased during HH (P < 0.05), except for phasic inspiratory PAL and phasic expiratory TP activities. Peak inspiratory LP and TP activities increased during HH to 250 and 179% of control, respectively, and peak expiratory activity increased to 187, 235, and 181% of control in PAL, LP, and TP, respectively. These findings demonstrate respiratory-related regulation of SPM activity independent of local reflex control from the upper airway. However, the combined inspiratory and expiratory phasic recruitment of these muscles differs from the inspiratory recruitment of known upper airway dilator muscles.

Abstract
We studied respiratory-related activity of the soft palate muscles in 10 anesthetized tracheostomized supine dogs. Moving time average (MTA) electromyographic (EMG) activity was measured in the palatinus (PAL), levator veli palatini (LP), and tensor veli palatini (TP) with bipolar fine-wire electrodes and in the diaphragm with bipolar hook electrodes. Measurements were made during tracheostomy breathing and nasal breathing with the mouth sealed (NB). During tracheostomy breathing, all soft palate muscles displayed respiratory-related phasic inspiratory and expiratory as well as tonic EMG activity. During NB, peak inspiratory EMG activity increased in PAL, LP, and TP because of an increase in both phasic inspiratory and tonic MTA activity. In contrast, phasic expiratory activity did not change. A constant negative pressure equal to peak inspiratory tracheal pressure during NB was applied to the caudal end of the isolated upper airway with the nose occluded. This was associated with soft palate muscle responses qualitatively similar to the responses during NB but accounted for only 39, 25, and 32% of the magnitude of the peak inspiratory MTA EMG responses to NB in PAL, LP, and TP, respectively. Our results demonstrate that the soft palate muscles exhibit respiratory-related activity in common with other upper airway muscles. Furthermore, such activity is augmented in each soft palate muscle during NB, and negative upper airway pressure makes a substantial contribution to the recruitment of soft palate muscle activity.

Abstract
In order to begin to evaluate the need for an integrated trauma management service for injured children, a retrospective review of deaths following admission to a suburban teaching hospital was conducted. The medical records and coroners' reports for 64 consecutive cases over 68 months were reviewed, looking for errors in care which may have contributed to fatal outcomes. There was a male predominance (64%). The main causes of death were pedestrian injuries (42%), drownings (20%), injuries to vehicular passengers (17%) and injuries to cyclists (13%). Errors, often multiple, occurred in 29 cases (45%). Errors most frequently involved airway control and ventilatory support (25%), volume replacement (19%) and delays in performing essential investigations (13%). Errors were most frequent at the referring hospitals (49% [17 of/35 referred cases], compared with 14% at the teaching hospital), and principally involved multiply injured victims of blunt trauma (81%, 13 of 16 patients). In only three cases (5%) would better management have salvaged the patient. This can be explained partly by the predominance of what were judged to be irretrievable intracranial injuries (90%) in patients suffering blunt injuries. In contrast, an analysis of the same patient group revealed that in 30-50% the fatality could have been prevented by the full application of well recognized safety strategies. While strategies such as triage and trauma teams should reduce the error rate, it is yet to be proven that optimal post-injury care will significantly reduce mortality.

Abstract
In order to determine the preventable factors in fatal accidents, a retrospective review of paediatric deaths after admission to a suburban teaching hospital was conducted. The medical records and coroners' reports for 64 consecutive cases over a 68-month period were reviewed. The main causes of death were pedestrian injuries (42% of deaths), drowning (20% of deaths) and injuries to vehicular passengers (17% of deaths) and cyclists (13% of deaths). There was a male predominance (64%). Children who were aged less than five years were at greatest risk at home, with death by drowning (46% of deaths) predominating. For children who were over five years of age, accidents on the roadway as pedestrians (58% of deaths) and pedal-cyclists (20% of deaths) were the most-common causes of death. Analysis of the accidents showed that preventive strategies were underutilized. Thirty per cent of deaths could have been avoided by the wearing of restraints in motor vehicles, the wearing of cycle-helmets and the proper use of swimming-pool barrier equipment. Adequate supervision of children who were less than 10 years of age at road crossings could have prevented a further 17% of deaths. In comparison, even the most-optimal postinjury care would have salvaged only 5% of the cases. Therefore, while the ideal organization of services after injury is a logical aim in the management of childhood trauma, if lives are to be saved, the main emphasis must be on prevention.

Abstract
To develop intuition on the possible application of concepts from thermodynamic heat engines to mesoscale systems, we have constructed and studied a model thermoacoustic heat engine. The model consists of a chain of coupled nonlinear acoustic vibrators in which the primary thermodynamic medium is argon gas, the secondary thermodynamic medium is constituted by solids bounding the gas, and frequencies are ca. 3 x 10(2) Hz. The nonlinear elements are the necks, made flexible by means of an oil-loaded DuPont Kapton film, of Helmholtz resonators. When the primary medium is driven uniformly by an acoustic driver at a frequency somewhat below the low-amplitude resonant frequency and at a high enough driving amplitude, stationary localized or solitary states appear irreversibly on the chain. These are characterized by a higher vibrational amplitude than that in surrounding vibrators, where the amplitude can decrease; by the appearance of deep subharmonics of the drive frequency, corresponding to driven low-frequency vibrations of the Kapton film-oil systems; and by the pumping of heat toward the localized states. Possible implications of these results for mesoscale systems consisting of chains of molecular vibrators are then discussed.

Abstract
A technique for self-examination of the oral cavity and head and neck has been presented. The technique is simple in its design and yet thorough in its scope. The need for such an examination is established on the incidence of malignancies in this area and the importance of early detection, diagnosis, and treatment. The role of dental auxiliaries and the role of risk factors are discussed.
