Impact of COVID-19 on clinical practice of UK-based speech and language therapists working with school-aged children with neurodisability and oropharyngeal dysphagia: A survey.

BACKGROUND: The COVID-19 pandemic and response changed clinical service delivery and practice for speech and language therapists (SLTs) in the United Kingdom. SLTs work with children with neurodisability regarding both difficulties with their communication and eating and drinking skills (oropharyngeal dysphagia). This survey aimed to specifically explore the impact of the COVID-19 pandemic on SLT practice for school-aged children with dysphagia. METHODS: UK-based SLTs working with school-aged children with neurodisability and oropharyngeal dysphagia were recruited to share their perceptions on the impact of COVID-19 on practice. Four questions focusing on COVID-19 impact were part of a larger online survey exploring SLT clinical practice regarding mealtime management of children with neurodisability and oropharyngeal dysphagia, which included demographic information, service delivery, assessment and intervention practices. COVID-19 impact questions were a mixture of multiple choice and free text responses. The survey was disseminated using professional networks and social media, between 14 May and 30 July 2021. Data were analysed using descriptive statistics and qualitative content analysis. RESULTS: One hundred and two participants answered at least one of the four COVID-19 questions. Eighty-two per cent of SLTs either agreed or strongly agreed that COVID-19 impacted on service delivery to children and families. Negative impacts on service delivery included school absences/closures, home visiting restrictions, families declining input and/or having barriers to telehealth use and the impact of mask wearing on interactions. Positive impacts included increased telehealth access and skills, increased contact with families and focus on children's eating and drinking function within the home environment. Participants aimed to maintain the increased contact with families alongside a hybrid service delivery approach of in-person and virtual appointments. CONCLUSIONS: This survey provides novel information capturing SLT practice change across two waves of COVID-19 and return to in-person practice for UK children with neurodisability.

Understanding Dysphagia Care in Pakistan: A Survey of Current Speech Language Therapy Practice.

Dysphagia affects individuals across all ages and has pervasive and potentially life-threatening consequences. Individuals with dysphagia are assessed and treated by speech and language therapists (SLTs), however, little attention has been paid to their practices in Pakistan. This study aimed to explore SLTs practices for dysphagia assessment, signs and symptoms observed during evaluation, and management strategies, alongside barriers and facilitators to service delivery in Pakistan. A 45-item survey was distributed to SLTs online. Responses were received from 101 participants and analyzed descriptively, and open-text responses were analyzed using content analysis. Results revealed that 65.3% SLTs worked across the lifespan, and most (79.4%) had dysphagia-related experience of five years or less. SLTs were an active workforce engaged with varying ages, disorders, and settings, yet dysphagia contributed to a small caseload percentage for most. Analyses found informal clinical exams were more frequently used than instrumental assessments. A variety of service provision facilitators were described, such as supportive teams and accessible resources, and responses about barriers revealed gaps in awareness, education, and guidance. This exploratory study presents novel and unexplored data which provides a deeper understanding of dysphagia-related care in Pakistan.

Blended diets for gastrostomy fed children and young people: a scoping review.

BACKGROUND: The present review aimed to identify what is known about the use of blended diets in gastrostomy fed children and young people (i.e. children and young people refers to those who are aged up to 25 years with special educational needs or a disability in accordance with Part 3 of the Children and Family Act 2014; within the review, the word children is used for simplicity but encompasses young people too) and to identify gaps in the literature on this topic to inform future research and policy. METHODS: A scoping review methodology was used searching the online databases PUBMED, PsychINFO, CINAHL, SCOPUS and AMED, EMBASE for articles that addressed issues pertaining to blended diets. The review identified a broad range of literature, regardless of study design, and described and evaluated the quality, range and nature of research activity related to the use of blenderised diets. RESULTS: Forty-three studies were included in the review. The studies focused on nutrition, equipment, the views of carers and patients, and the views of professionals. Several studies described the lack of evidence regarding pros and cons of blended diets and highlighted the need for further research into the field. CONCLUSIONS: There were gaps in the evidence base regarding the impact of blended diets on the health and well-being of the children who receive them and upon the carers who feed the children. The nutritional impact of blended diets is not fully understood and the knowledge and views of professionals involved in the care of those receiving blended diets varies.

Dexamethasone and supportive care with or without whole brain radiotherapy in treating patients with non-small cell lung cancer with brain metastases unsuitable for resection or stereotactic radiotherapy (QUARTZ): results from a phase 3, non-inferiority, randomised trial.

BACKGROUND: Whole brain radiotherapy (WBRT) and dexamethasone are widely used to treat brain metastases from non-small cell lung cancer (NSCLC), although there have been no randomised clinical trials showing that WBRT improves either quality of life or overall survival. Even after treatment with WBRT, the prognosis of this patient group is poor. We aimed to establish whether WBRT could be omitted without a significant effect on survival or quality of life. METHODS: The Quality of Life after Treatment for Brain Metastases (QUARTZ) study is a non-inferiority, phase 3 randomised trial done at 69 UK and three Australian centres. NSCLC patients with brain metastases unsuitable for surgical resection or stereotactic radiotherapy were randomly assigned (1:1) to optimal supportive care (OSC) including dexamethasone plus WBRT (20 Gy in five daily fractions) or OSC alone (including dexamethasone). The dose of dexamethasone was determined by the patients' symptoms and titrated downwards if symptoms improved. Allocation to treatment group was done by a phone call from the hospital to the Medical Research Council Clinical Trials Unit at University College London using a minimisation programme with a random element and stratification by centre, Karnofsky Performance Status (KPS), gender, status of brain metastases, and the status of primary lung cancer. The primary outcome measure was quality-adjusted life-years (QALYs). QALYs were generated from overall survival and patients' weekly completion of the EQ-5D questionnaire. Treatment with OSC alone was considered non-inferior if it was no more than 7 QALY days worse than treatment with WBRT plus OSC, which required 534 patients (80% power, 5% [one-sided] significance level). Analysis was done by intention to treat for all randomly assigned patients. The trial is registered with ISRCTN, number ISRCTN3826061. FINDINGS: Between March 2, 2007, and Aug 29, 2014, 538 patients were recruited from 69 UK and three Australian centres, and were randomly assigned to receive either OSC plus WBRT (269) or OSC alone (269). Baseline characteristics were balanced between groups, and the median age of participants was 66 years (range 38-85). Significantly more episodes of drowsiness, hair loss, nausea, and dry or itchy scalp were reported while patients were receiving WBRT, although there was no evidence of a difference in the rate of serious adverse events between the two groups. There was no evidence of a difference in overall survival (hazard ratio 1·06, 95% CI 0·90-1·26), overall quality of life, or dexamethasone use between the two groups. The difference between the mean QALYs was 4·7 days (46·4 QALY days for the OSC plus WBRT group vs 41·7 QALY days for the OSC group), with two-sided 90% CI of -12·7 to 3·3. INTERPRETATION: Although the primary outcome measure result includes the prespecified non-inferiority margin, the combination of the small difference in QALYs and the absence of a difference in survival and quality of life between the two groups suggests that WBRT provides little additional clinically significant benefit for this patient group.

Tracheoesophageal Voice Therapy in Postlaryngectomy Rehabilitation: A Systematic Review.

BACKGROUND: Following total laryngectomy, surgical voice restoration is considered the optimal modality for re-establishing communication via tracheoesophageal voice. Yet beyond the insertion of a voice prosthesis to elicit voice production, there is suboptimal clinical knowledge of how to rehabilitate the perceptual quality of tracheoesophageal voice. This systematic review will identify and critically evaluate the quality and effectiveness of therapeutic interventions for tracheoesophageal voice. The findings of this review will inform the development of a novel tracheoesophageal voice therapy intervention. STUDY DESIGN: Systematic literature review carried out in accordance with PRISMA guidelines. METHODS: The review protocol was registered with PROSPERO. Eight electronic databases were searched using a prespecified search strategy. Records were independently screened by two reviewers against inclusion and exclusion criteria. Eligible studies were assessed for quality using the PEDro, ROBIN-T, and NHLBI critical appraisal tools. Data was extracted pertaining to participant characteristics and the content, dosage, intensity and outcomes of interventions. RESULTS: 6344 records were identified, of which 38 were included for full-text review. Six studies met the eligibility criteria for inclusion. Voice rehabilitation was not the primary focus in the majority of studies, and the risk of bias was identified across studies. There was significant heterogeneity in the interventions and outcome measures used within studies with insufficient detail provided on intervention content for tracheoesophageal voice. Evidence for the effectiveness of interventions was limited and inconsistent across studies. CONCLUSIONS: This review found that tracheoesophageal voice therapy is an under-researched area of clinical practice. Evidence from the small body of existing studies was not sufficiently robust to inform clinical practice at this time. This review highlights the necessity to develop and test interventions aimed at improving the perceptual quality of tracheoesophageal voice.

A service evaluation of parent adherence with dysphagia management therapy guidelines: reports from family carers supporting children with complex needs in Greece.

Purpose: Many children with complex needs exhibit eating, drinking, and/or swallowing disorders (dysphagia). These children often have associated learning needs, and require assistance from carers for daily tasks such as eating and drinking. The aim of this study was to identify which strategies to manage dysphagia were challenging for family carers, and reasons for any non-adherence.Method: In this service evaluation researchers observed carers during mealtimes, and investigated carer opinions of strategies used to minimise the risks of dysphagia. Eight children with complex needs aged 3.4-7.5 years and their primary family caregiver participated.Results: Adherence with speech and language pathologists' dysphagia recommendations overall was over 50% in all but one case. For specific strategies, the highest adherence was observed for diet modifications of foods (89%), communication during the mealtime (83%), amount of food to present (81%), and the pacing of fluids and foods (81%). Lower levels of adherence were identified in relation to postural management (58%), environmental changes (58%), utensils (56%), and preparatory strategies (49%).Conclusions: Adherence with use of strategies to support mealtimes was over 50% in all but one case. Findings suggest that support is essential to promote safe mealtimes, reduce family carers' stress and increase knowledge, confidence, and adherence in implementing dysphagia guidelines in the family home. Implications for rehabilitationDifficulties with eating, drinking and swallowing (dysphagia) can impact on the parent-child mealtime experience.Mealtime strategies as recommended by a speech-language pathologist can support children who have difficulties eating, drinking, and swallowing.Some strategies to support eating, drinking, and swallowing are easier for carers to adhere to than others.

Volume based feeding versus rate based feeding in the critically ill: A UK study.

BACKGROUND: Underfeeding in intensive care patients on enteral nutrition is commonplace and multifactorial. This can be exacerbated by interruptions caused by routine fasting for procedures and investigations. Our study aims to demonstrate that a volume based feeding protocol can overcome the barriers of underfeeding and safely increase energy and protein delivery in UK intensive care patients, potentially improving clinical outcomes. METHODS: In this single centre cohort study, data were collected from adult mechanically ventilated patients. We compared the standard care of rate based feeding, from an International Nutrition Survey (2014/15) to the new intervention of volume based feeding, in a mixed medical and surgical intensive care unit. The primary outcomes were the proportion of energy and protein daily targets delivered. Secondary outcomes compared the effects on gastrointestinal tolerance, glycaemic control, mortality, mechanical ventilation days, length of stay in intensive care unit and hospital. RESULTS: From a total of 82 patients (rate based feeding = 27, volume based feeding = 55), volume based feeding patients received significantly more prescribed energy (52% versus 81%; p < 0.001) and protein (40% versus 74%; p < 0.001). There was no significant difference in gastrointestinal symptoms such as gastric residual volumes (p = 0.62), glycaemic control (p = 0.94) or insulin usage (p = 0.75). Although there was an improvement in energy and protein delivery, there were no differences in mechanical ventilation days (p = 0.12), mortality (p = 0.06), length of stay in intensive care unit (p = 0.93) and hospital (p = 0.72) between the groups. CONCLUSION: Compared to rate based feeding, volume based feeding significantly improved energy and protein provision with no adverse effects on glycaemic control or gastrointestinal tolerance, clinical outcomes were not affected.

Clear Lake sediments: anthropogenic changes in physical sedimentology and magnetic response.

We analyzed the sedimentological characteristics and magnetic properties of cores from the three basins of Clear Lake, California, USA, to assess the depositional response to a series of land use changes that occurred in the watershed over the 20th century. Results indicate that distinct and abrupt shifts in particle size, magnetic concentration/mineralogy, and redox conditions occur concurrently with a variety of ecological and chemical changes in lake bed sediments. This coincidence of events occurred around 1927, a datum determined by an abrupt increase in total mercury (Hg) in Clear Lake cores and the known initiation of open-pit Hg mining at the Sulphur Bank Mercury Mine, confirmed by 210Pb dating. Ages below the 1927 horizon were determined by accelerator mass spectrometry on 14C of coarse organic debris. Calculated sedimentation rates below the 1927 datum are approximately 1 mm/yr, whereas rates from 1927 to 2000 are up to an order of magnitude higher, with averages of approximately 3.5-19 mm/yr. In both the Oaks and Upper Arms, the post-1927 co-occurrence of abrupt shifts in magnetic signatures with color differences indicative of changing redox conditions is interpreted to reflect a more oxygenated diagenetic regime and rapid burial of sediment below the depth of sulfate diffusion. Post-1927 in the Oaks Arm, grain size exhibits a gradual coarsening-upward pattern that we attribute to the input of mechanically deposited waste rock related to open-pit mining activities at the mine. In contrast, grain size in the Upper Arm exhibits a gradational fining-upward after 1927 that we interpret as human-induced erosion of fine-grained soils and chemically weathered rocks of the Franciscan Assemblage by heavy earthmoving equipment associated with a road- and home-building boom, exacerbated by stream channel mining and wetlands destruction. The flux of fine-grained sediment into the Upper Arm increased the nutrient load to the lake, and that in turn catalyzed profuse cyanobacterial blooms through the 20th century. The resulting organic biomass, in combination with the increased inorganic sediment supply, contributed to the abrupt increase in sedimentation rate after 1927.

Continuous hyperfractionated accelerated radiotherapy - Escalated dose (CHART-ED): A phase I study.

INTRODUCTION: Patients who present with locally advanced inoperable non-small cell lung cancer (NSCLC) may be suitable for radical radiotherapy. A randomised trial of 563 patients compared CHART and conventional radical radiotherapy (60 Gy/30f) given over 6 weeks and suggested that CHART resulted in a 9% improvement in 2-year survival (Saunders et al., 1999). RT dose escalation for both conventional and CHARTWEL (CHART-WeekEndLess) - fractionation schedules is feasible with modern 3-dimensional CT-based planning techniques and we initiated a phase I CHART dose escalation study in 2009. METHODS: Patients with WHO performance status 0-2 histologically confirmed, inoperable, stage I-III non-small cell lung cancer were recruited into an open phase I dose escalation trial. Three cohorts of six patients were recruited sequentially. Total dose was escalated from standard CHART radiotherapy of 54 Gy/36f/12 days to 57.6G y (2 × 1.8 Gy fractions on day 15, Group 1), 61.2 Gy (4 × 1.8 Gy fractions on days 15-16, Group 2) and 64.8 Gy (6 × 1.8 Gy fractions on days 15-17, Group 3). RESULTS: Between April 2010 and May 2012, 18 patients were enrolled from 5 UK centres and received escalated dose radiotherapy. 14 were male, 16 squamous cell histology and 12 were stage IIIA or IIIB. The median age was 70 years and baseline characteristics were similar across the three dose cohorts. One patient did not start escalated radiotherapy but all remaining patients completed their planned radiotherapy schedules. Of these 9 patients have died to date with a median survival of 2 years across the three cohorts. Grade 3 or 4 adverse events (fatigue, dysphagia, nausea and anorexia - classified according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0) were reported in 6 patients but the pre-specified dose limiting toxicities (grade 4 early oesophagitis; grade 3 cardiac, spinal cord and pneumonitis) were not observed. CONCLUSIONS: CHART remains a radiotherapy schedule in routine use across the UK and in this dose escalation study no dose limiting toxicities were observed. We feel the dose of 64.8 Gy/42f/17 days should be taken forward into further clinical trials. The sample size used in this study was small so we plan a randomised phase II study that includes other radiotherapy schedules to confirm safety and select an accelerated sequential chemo-radiotherapy schedule to take into phase III studies.

Nurses' Attitudes Regarding the Safe Handling of Patients Who Are Morbidly Obese: Instrument Development and Psychometric Analysis.

BACKGROUND AND PURPOSE: Nurses' attitudes play an important role in the consistent practice of safe patient handling behaviors. The purposes of this study were to develop and assess the psychometric properties of a newly developed instrument measuring attitudes of nurses related to the care and safe handling of patients who are obese. METHODS: Phases of instrument development included (a) item generation, (b) content validity assessment, (c) reliability assessment, (d) cognitive interviewing, and (e) construct validity assessment through factor analysis. RESULTS: The final data from the exploratory factor analysis produced a 26-item multidimensional instrument that contains 9 subscales. CONCLUSIONS: Based on the factor analysis, a 26-item instrument can be used to examine nurses' attitudes regarding patients who are morbidly obese and related safe handling practices.

Assessing progress during treatment for young children with autism receiving intensive behavioural interventions.

This study examined progress after 1 year of treatment for children with autism who received a mean of 36 hours per week one-to-one University of California at Los Angeles Applied Behavior Analysis (UCLA ABA) treatment. Two types of service provision were compared: an intensive clinic based treatment model with all treatment personnel (N = 23), and an intensive parent managed treatment model with intensive supervision only (N = 21). A non-concurrent multiple baseline design across participants (N = 13) examined whether progress was associated with ABA treatment or confounders. Between intake and follow-up, children in both groups improved significantly on IQ, visual-spatial IQ, language comprehension, expressive language, social skills, motor skills and adaptive behaviour. There were no significant differences between the two groups on any of the measures at follow-up. Mean IQ for participants in both groups increased by 16 points between intake and follow-up. These findings are consistent with previous studies demonstrating the benefits of ABA treatment.

Routine use of continuous, hyperfractionated, accelerated radiotherapy for non-small-cell lung cancer: a five-center experience.

PURPOSE: To report the results from continuous, hyperfractionated, accelerated radiotherapy (CHART) used as the standard fractionation for radical RT in the management of non-small cell lung cancer (NSCLC) in five United Kingdom centers. METHODS AND MATERIALS: In 2005, the CHART consortium identified six U.K. centers that had continued to use CHART after the publication of the CHART study in 1997. All centers had been using CHART for >5 years and agreed to use a common database to audit their results. Patients treated with CHART between 1998 and December 2003 were identified to allow a minimum of 2 years of follow-up. Patient demographics, tumor characteristics, treatment details, and survival were recorded retrospectively. Five centers completed the data collection. RESULTS: A total of 583 patients who had received CHART were identified. Of these patients, 69% were male, with a median age of 68 years (range, 31-89); 83% had performance status 0 or 1; and 43% had Stage I or II disease. Of the 583 patients, 99% received the prescribed dose. In only 4 patients was any Grade 4-5 toxicity documented. The median survival from the start of RT was 16.2 months, and the 2-year survival rate of 34% was comparable to that reported in the original study. CONCLUSION: The results of this unselected series have confirmed that CHART is deliverable in routine clinical practice, with low levels of toxicity. Importantly, this series has demonstrated that the results of CHART reported from the randomized trial can be reproduced in routine clinical practice.

Drilling to gabbro in intact ocean crust.

Sampling an intact sequence of oceanic crust through lavas, dikes, and gabbros is necessary to advance the understanding of the formation and evolution of crust formed at mid-ocean ridges, but it has been an elusive goal of scientific ocean drilling for decades. Recent drilling in the eastern Pacific Ocean in Hole 1256D reached gabbro within seismic layer 2, 1157 meters into crust formed at a superfast spreading rate. The gabbros are the crystallized melt lenses that formed beneath a mid-ocean ridge. The depth at which gabbro was reached confirms predictions extrapolated from seismic experiments at modern mid-ocean ridges: Melt lenses occur at shallower depths at faster spreading rates. The gabbros intrude metamorphosed sheeted dikes and have compositions similar to the overlying lavas, precluding formation of the cumulate lower oceanic crust from melt lenses so far penetrated by Hole 1256D.

Colon cancer: prevention, diagnosis, treatment.

Colorectal cancer is the second leading cause of death from cancer in the United States. It is third leading cause of cancer death in men behind lung and prostate respectively, and behind lung and breast in cancer deaths among women. More than 130,000 cases are diagnosed each year with over 56,000 of those patients dying. Six percent of the United States population will develop colorectal cancer in their lifetime.
