Transanal versus conventional total mesorectal excision for rectal cancer using the IDEAL framework for implementation

Background

Transanal total mesorectal excision (TaTME) is an innovative technique for distal rectal cancer dissection. It has been shown to have similar short-term outcomes to conventional open and laparoscopic total mesorectal excision (cTME), but recent studies have raised concern about increased morbidity and local recurrence rates. The aim of this study was to assess outcomes after TaTME versus cTME for rectal cancer.

Methods

TaTME was implemented in 2014 using IDEAL principles in a single institution. The institution maintains databases for all patients undergoing rectal cancer surgery. This retrospective review compared data collected from all patients who had TaTME with those from a propensity-matched cohort of patients who underwent cTME. The primary outcome was a composite pathological measure combining margin status and quality of total mesorectal excision (TME). Short-term clinical and survival outcomes were also measured.

Results

Propensity matching created 109 matched pairs for analysis. Nine patients (8.3 per cent) undergoing TaTME had positive margins and/or incomplete TME, compared with 11 (10.5 per cent) undergoing cTME (P = 0.65). There were no significant differences in morbidity between the TaTME and cTME groups, including number of anastomotic leaks (13.8 versus 18.3 per cent; P = 0.37). The estimated 3-year local recurrence-free survival rate was 96.3 per cent in both groups (P = 0.39). Estimated 3-year overall (93.6 per cent for TaTME versus 94.5 per cent for cTME; P = 0.09) and disease-free (88.1 versus 76.1 per cent; P = 0.90) survival rates were similar.

Conclusion

TaTME provided similar outcomes to cTME for rectal cancer with the application of IDEAL principles.

Implementation of a novel antimicrobial stewardship strategy for rural facilities utilising telehealth

A significant portion of healthcare takes place in small hospitals, and many are located in rural and regional areas. Facilities in these regions frequently do not have adequate resources to implement an onsite antimicrobial stewardship programme and there are limited data relating to their implementation and effectiveness. We present an innovative model of providing a specialist telehealth antimicrobial stewardship service utilising a centralised service (Queensland Statewide Antimicrobial Stewardship Program) to a rural Hospital and Health Service. Results of a 2-year post-implementation follow-up showed an improvement in adherence to guidelines [33.7% (95% CI 27.0-40.4%) vs. 54.1% (95% CI 48.7-59.5%)] and appropriateness of antimicrobial prescribing [49.0% (95% CI 42.2-55.9%) vs. 67.5% (95% CI 62.7-72.4%) (P < 0.001). This finding was sustained after adjustment for hospitals, with improvement occurring sequentially across the years for adherence to guidelines [adjusted odds ratio (aOR) = 2.44, 95% CI 1.70-3.51] and appropriateness of prescribing (aOR = 2.48, 95% CI 1.70-3.61). There was a decrease in mean total antibiotic use (DDDs/1000 patient-days) between the years 2016 (52.82, 95% CI 44.09-61.54) and 2018 (39.74, 95% CI 32.76-46.73), however this did not reach statistical significance. Additionally, there was a decrease in mean hospital length of stay (days) from 2016 (3.74, 95% CI 3.08-4.41) to 2018 (2.55, 95% CI 1.98-3.12), although this was not statistically significant. New telehealth-based models of antimicrobial stewardship can be effective in improving prescribing in rural areas. Programmes similar to ours should be considered for rural facilities.

Validation of the factors influencing family consent for organ donation in the UK

Between 2013 and 2019, there was an increase in the consent rate for organ donation in the UK from 61% to 67%, but this remains lower than many European countries. Data on all family approaches (16,896) for donation in UK intensive care units or emergency departments between April 2014 and March 2019 were extracted from the referral records and the national potential donor audit held by NHS Blood and Transplant. Complete data were available for 15,465 approaches. Consent for donation after brain death was significantly higher than for donation after circulatory death, 70% (4260/6060) vs. 60% (5645/9405), (OR 1.58, 95%CI 1.47-1.69). Patient ethnicity, religious beliefs, sex and socio-economic status, and knowledge of a patient's donation decision were strongly associated with consent (p < 0.001). These factors should be addressed by medium- to long-term strategies to increase community interventions, encouraging family discussions regarding donation decisions and increasing registration on the organ donor register. The most readily modifiable factor was the involvement of an organ donation specialist nurse at all stages leading up to the approach and the approach itself. If no organ donation specialist nurse was present, the consent rates were significantly lower for donation after brain death (OR 0.31, 95%CI 0.23-0.42) and donation after cardiac death (OR 0.26, 95%CI 0.22-0.31) compared with if a collaborative approach was employed. Other modifiable factors that significantly improved consent rates included less than six relatives present during the formal approach; the time from intensive care unit admission to the approach (less for donation after brain death, more for donation after cardiac death); family not witnessing neurological death tests; and the relationship of the primary consenter to the patient. These modifiable factors should be taken into consideration when planning the best bespoke approach to an individual family to discuss the option of organ donation as an end-of-life care choice for the patient.

"It's the single best thing I've done in the last 10 years": a qualitative study exploring patient and dietitian experiences with, and perceptions of, a multi-component dietary weight loss program for knee osteoarthritis

OBJECTIVE

Explore patient and dietitian experiences with a multi-component dietary weight loss program for knee osteoarthritis to understand enablers and challenges to success at 6-months.

DESIGN

Qualitative study embedded within a randomised controlled trial. Semi-structured individual interviews with 24 patients with knee osteoarthritis who undertook, and five dietitians who supervised, a weight management program (involving a ketogenic very low calorie diet (VLCD), video consultations, educational resources) over 6 months. Data were thematically analysed.

RESULTS

Five themes were developed: (1) ease and convenience of program facilitated adherence (structure and simplicity of the meal replacements; not feeling hungry on diet; convenience of consulting via video) (2) social and professional support crucial for success (encouragement from partner, family, and friends; guidance from, and accountability to, dietitian; anxiety around going at it alone) (3) program was engaging and motivating (determination to stick to program; rapid weight loss helped motivation) (4) holistic nature of program was important (suite of high-quality educational resources; exercise important to compliment weight loss) (5) rewarding experience and lifelong impact (improved knee pain and function; positive lifestyle change).

CONCLUSIONS

Patients and dietitians described positive experiences with the weight management program, valuing its simplicity, effectiveness, and convenience. Support from dietitians and a comprehensive suite of educational resources, incorporated with an exercise program, were considered crucial for success. Findings suggest this multi-component dietary program is an acceptable weight loss method in people with knee osteoarthritis that may benefit symptoms. Strategies for supporting long-term independent weight management should be a focus of future research.

An Integrated Approach for High-Shear Wet Granulation (HSWG) Processing of TPGS-Based Formulations: Demonstration of Process Robustness through Experimental Design Conditions

The goal of this study was to understand the impact of high-shear wet granulation (HSWG) processing conditions on product attributes for a tablet formulation containing the non-ionic surfactant TPGS. The use of TPGS in oral solid drug products has been reported to be challenging due to the low melting temperature of TPGS. In addition, literature on TPGS-based HSWG formulations, especially practical processing and scale-up knowledge, is limited. Presented here is an extension of this TPGS application in a tablet formulation, with a focus on the HSWG processing and scale-up across different granulators. To understand the processing space for this TPGS-based HSWG formulation, two consecutive studies were conducted with different objectives. First, an exploratory study was conducted to understand the impact of extreme processing conditions on product attributes. Subsequently, a factorial design of experiment (DoE) study assessed the separate contributions and interactions from HSWG processing variables. The outcome of both studies led to a successful process scale-up and product transfer from lab to commercial development using different granulators. The TPGS-based formulation was demonstrated to provide robust downstream processing (improved flowability and reduced segregation potential) within a wide HSWG operating space, while having a minimal impact on product performance across different granulators.

In depth analysis of patients with severe SARS-CoV-2 in sub-Saharan Africa demonstrates distinct clinical and immunological profiles

Although the COVID-19 pandemic has left no country untouched there has been limited research to understand clinical and immunological responses in African populations. Here we comprehensively characterise patients hospitalised with suspected or confirmed COVID-19, and healthy community controls. PCR-confirmed COVID-19 participants were more likely to receive dexamethasone and a beta-lactam antibiotic, and survive to hospital discharge than PCR-/IgG+ and PCR-/IgG-participants. PCR-/IgG+ participants exhibited a nasal and systemic cytokine signature analogous to PCR-confirmed COVID-19 participants, but increased propensity for Staphylococcus aureus and Streptococcus pneumoniae colonisation. We did not find evidence that HIV co-infection in COVID-19 participants was associated with mortality or altered cytokine responses. The nasal immune signature in PCR-/IgG+ and PCR-confirmed COVID-19 participants was distinct and predominated by chemokines and neutrophils. In addition, PCR-/IgG+ individuals with high COVID-19 clinical suspicion had inflammatory profiles analogous to PCR-confirmed disease and potentially represent a target population for COVID-19 treatment strategies.

Long-term safety and efficacy of tezacaftor-ivacaftor in individuals with cystic fibrosis aged 12 years or older who are homozygous or heterozygous for Phe508del CFTR (EXTEND): an open-label extension study

BACKGROUND

Tezacaftor-ivacaftor is an approved cystic fibrosis transmembrane conductance regulator (CFTR) modulator shown to be efficacious and generally safe and well tolerated over 8-24 weeks in phase 3 clinical studies in participants aged 12 years or older with cystic fibrosis homozygous for the Phe508del CFTR mutation (F/F; study 661-106 [EVOLVE]) or heterozygous for the Phe508del CFTR mutation and a residual function mutation (F/RF; study 661-108 [EXPAND]). Longer-term (>24 weeks) safety and efficacy of tezacaftor-ivacaftor has not been assessed in clinical studies. Here, we present results of study 661-110 (EXTEND), a 96-week open-label extension study that assessed long-term safety, tolerability, and efficacy of tezacaftor-ivacaftor in participants aged 12 years or older with cystic fibrosis who were homozygous or heterozygous for the Phe508del CFTR mutation.

METHODS

Study 661-110 was a 96-week, phase 3, multicentre, open-label study at 170 clinical research sites in Australia, Europe, Israel, and North America. Participants were aged 12 years or older, had cystic fibrosis, were homozygous or heterozygous for Phe508del CFTR, and completed one of six parent studies of tezacaftor-ivacaftor: studies 661-103, 661-106, 661-107, 661-108, 661-109, and 661-111. Participants received oral tezacaftor 100 mg once daily and oral ivacaftor 150 mg once every 12 h for up to 96 weeks. The primary endpoint was safety and tolerability. Secondary endpoints were changes in lung function, nutritional parameters, and respiratory symptom scores; pulmonary exacerbations; and pharmacokinetic parameters. A post-hoc analysis assessed the rate of lung function decline in F/F participants who received up to 120 weeks of tezacaftor-ivacaftor in studies 661-106 (F/F) and/or 661-110 compared with a matched cohort of CFTR modulator-untreated historical F/F controls from the Cystic Fibrosis Foundation Patient Registry. Primary safety analyses were done in all participants from all six parent studies who received at least one dose of study drug during this study. This study was registered at ClinicalTrials.gov (NCT02565914).

FINDINGS

Between Aug 31, 2015, to May 31, 2019, 1044 participants were enrolled in study 661-110 from the six parent studies of whom 1042 participants received at least one dose of study drug and were included in the safety set. 995 (95%) participants had at least one TEAE; 22 (2%) had TEAEs leading to discontinuation; and 351 (34%) had serious TEAEs. No deaths occurred during the treatment-emergent period; after the treatment-emergent period, two deaths occurred, which were both deemed unrelated to study drug. F/F (106/110; n=459) and F/RF (108/110; n=226) participants beginning tezacaftor-ivacaftor in study 661-110 had improvements in efficacy endpoints consistent with parent studies; improvements in lung function and nutritional parameters and reductions in pulmonary exacerbations observed in the tezacaftor-ivacaftor groups in the parent studies were generally maintained in study 661-110 for an additional 96 weeks. Pharmacokinetic parameters were also similar to those in the parent studies. The annualised rate of lung function decline was 61·5% (95% CI 35·8 to 86·1) lower in tezacaftor-ivacaftor-treated F/F participants versus untreated matched historical controls.

INTERPRETATION

Tezacaftor-ivacaftor was generally safe, well tolerated, and efficacious for up to 120 weeks, and the safety profile of tezacaftor-ivacaftor in study 661-110 was consistent with cystic fibrosis manifestations and with the safety profiles of the parent studies. The rate of lung function decline was significantly reduced in F/F participants, consistent with cystic fibrosis disease modification. Our results support the clinical benefit of long-term tezacaftor-ivacaftor treatment for people aged 12 years or older with cystic fibrosis with F/F or F/RF genotypes.

Preparations for a European R&D roadmap for an inertial fusion demo reactor

A European consortium of 15 laboratories across nine nations have worked together under the EUROFusion Enabling Research grants for the past decade with three principle objectives. These are: (a) investigating obstacles to ignition on megaJoule-class laser facilities; (b) investigating novel alternative approaches to ignition, including basic studies for fast ignition (both electron and ion-driven), auxiliary heating, shock ignition, etc.; and (c) developing technologies that will be required in the future for a fusion reactor. A brief overview of these activities, presented here, along with new calculations relates the concept of auxiliary heating of inertial fusion targets, and provides possible future directions of research and development for the updated European Roadmap that is due at the end of 2020. This article is part of a discussion meeting issue 'Prospects for high gain inertial fusion energy (part 2)'.

Whole-beam self-focusing in fusion-relevant plasma

Fast ignition inertial confinement fusion requires the production of a low-density channel in plasma with density scale-lengths of several hundred microns. The channel assists in the propagation of an ultra-intense laser pulse used to generate fast electrons which form a hot spot on the side of pre-compressed fusion fuel. We present a systematic characterization of an expanding laser-produced plasma using optical interferometry, benchmarked against three-dimensional hydrodynamic simulations. Magnetic fields associated with channel formation are probed using proton radiography, and compared to magnetic field structures generated in full-scale particle-in-cell simulations. We present observations of long-lived, straight channels produced by the Habara-Kodama-Tanaka whole-beam self-focusing mechanism, overcoming a critical barrier on the path to realizing fast ignition. This article is part of a discussion meeting issue 'Prospects for high gain inertial fusion energy (part 2)'.

Teaching young consumers in Europe: a multicentre qualitative needs assessment with educators on food hygiene and food safety

AIM

Foodborne illnesses have a significant global burden and can be life-threatening, with higher risk in vulnerable groups such as children. SafeConsume is an EU-funded, transdisciplinary project aiming to improve consumers' food safety behaviour. Developing educational resources on food safety for use in schools has potential to improve teaching of our young consumers. The aim of this study was to explore school educators' attitudes, behaviours and knowledge towards food hygiene, safety and education.

METHODS

Focus groups and interviews in England, France, Portugal and Hungary explored educator knowledge, skills, intentions and beliefs around educating young people (11-18 years) about food safety. Data were analysed using NVivo and emerging themes were applied to the Theoretical Domains Framework.

RESULTS

A total of 48 educators participated. Knowledge, confidence and skills to teach food safety to young people varied depending on background and training. Educators reported they had a role to teach food safety to young people, were positive about delivering education and optimistic they could improve students' food safety behaviour. Barriers to teaching included lack of national curriculum coverage, limited time and money, and lack of facilities. Educators reported that social influences (family, celebrity chefs, public health campaigns and social media) were important opportunities to improve young peoples' awareness of food safety and consequences of foodborne illness.

CONCLUSION

Educator food safety expertise varied; training could help to optimise educator knowledge, confidence and skills. Ministries of Health and Education need encouragement to get food safety incorporated further into school curricula across Europe, so schools will be motivated to prioritise these topics.

Life-Space in a National Cohort of U.S. Older Adults: Normative Data for the UAB Life-Space Assessment

The University of Alabama at Birmingham Life-Space Assessment (LSA) is a self-reported measure for assessing community mobility. Restricted mobility is correlated with a number of adverse health outcomes, including mortality, frailty, cognitive decline, and nursing home admissions. Thus, it is important for providers to understand how the LSA score of a patient compares to the general population. To facilitate such comparisons, we developed demographically adjusted norms for the LSA and its correlation with other functional measures. Norms were based on 15,390 participants age 45 and older in the National Institutes of Health-funded REasons for Geographic and Racial Differences in Stroke (REGARDS) study, a national, population-based, longitudinal study investigating the causes of excess stroke mortality among African Americans and individuals living in the Southeastern US stroke belt region. LSA scores declined from a median of 100 in the 45-54 age range to a median of 59.7 in the 85 and older age range, with higher median scores in males. LSA scores showed modest but significant positive correlations with SF-12 Physical Component and Mental Component, Center for Epidemiologic Studies Depression Scale, and Six Item Screener cognitive scores, as well as modest but significant negative correlations with AD8 Dementia Screening, Katz Activities of Daily Living, and Timed Walk scores. The LSA is a brief, easily administered measure that offers a valid method of assessing community mobility in the older adult population.

The impact of COVID-19 on rare metabolic patients and healthcare providers: results from two MetabERN surveys

The ongoing coronavirus disease 2019 (COVID-19) pandemic has caused disruption in all aspects of daily life, including the management and treatment of rare inherited metabolic disorders (IMDs). To perform a preliminary assessment of the incidence of COVID-19 in IMD patients and the impact of the coronavirus emergency on the rare metabolic community between March and April 2020, the European Reference Network for Hereditary Metabolic Diseases (MetabERN) has performed two surveys: one directed to patients’ organizations (PO) and one directed to healthcare providers (HCPs). The COVID-19 incidence in the population of rare metabolic patients was lower than that of the general European population (72.9 × 100,000 vs. 117 × 100,000). However, patients experienced extensive disruption of care, with the majority of appointments and treatments cancelled, reduced, or postponed. Almost all HCPs (90%) were able to substitute face-to-face visits with telemedicine, about half of patients facing treatment changes switched from hospital to home therapy, and a quarter reported difficulties in getting their medicines. During the first weeks of emergency, when patients and families lacked relevant information, most HCPs contacted their patients to provide them with support and information. Since IMD patients require constant follow-up and treatment adjustments to control their disease and avoid degradation of their condition, the results of our surveys are relevant for national health systems in order to ensure appropriate care for IMD patients. They highlight strong links in an interconnected community of HCPs and PO, who are able to work quickly and effectively together to support and protect fragile persons during crisis. However, additional studies are needed to better appreciate the actual impact of COVID-19 on IMD patients’ health and the mid- and long-term effects of the pandemic on their wellbeing.

Hypofractionated adjuvant surgical cavity radiotherapy following resection of limited brain metastasis

BACKGROUND

Following surgical resection of oligometastatic disease to the brain there is a high rate of local relapse which is reduced by the addition of focal radiation therapy, often delivered as single fraction stereotactic radiosurgery (SRS) to the surgical cavity. This study audited the outcomes of an alternative approach using hypofractionated radiation therapy (HFRT) to the surgical resection cavity.

METHODS AND MATERIALS

Seventy-nine patients who received surgical resection and focal radiation therapy to the surgical cavity using HFRT with intensity modulated radiation therapy with or without stereotactic radiotherapy were identified. Doses were delivered in five fractions every second day for 10 days. Follow-up involved MRI surveillance with three-monthly MRI scans post resection. The major endpoints were local control at the surgical cavity site, and presence of radiation necrosis at the treated site.

RESULTS

Seventy-nine patients were included for the analysis with a median follow-up of 10.8 months. Of the cohort, 56% experienced intracranial progression, with all patients progressing distant to the resection cavity, and 7% progressing locally in addition. The one-year local control rate was 89.8%. The median progression-free survival was 10.0 months and median overall survival was 14.3 months. There was one CTCAE grade 3 toxicity of symptomatic radiation necrosis with no grade 4-5 toxicities seen.

CONCLUSIONS

The rate of local relapse following HFRT to the surgical cavity is low with minimal risk of radiation necrosis. HFRT can be considered as an alternative to SRS for focal radiotherapy after brain metastasis resection.

Cardiovascular risk and missed opportunities for treatment in patients with type 2 diabetes presenting with very premature coronary artery disease

Background

Type 2 diabetes mellitus (T2D) is a major cardiovascular risk factor (CVRF), and comprehensive risk factor management reduces the incidence of cardiovascular events.

Purpose

To assess 1) prevalence of T2D among patients presenting with newly diagnosed very premature coronary artery disease (CAD) and its impact on CVRFs and extent of atherosclerosis; 2) effectiveness of glucose and lipid control in T2D patients before presentation with CAD.

Methods

We studied patients with angiographically proven CAD with stenosis of ≥50% who presented at the age of ≤50 years for males and ≤55 years for females. Diabetes was defined as fasting plasma glucose ≥7 mmol/L, haemoglobin (Hb)A1C ≥6.5% or diagnosis or treatment of T2D before or at presentation with CAD. CVRFs were defined as dyslipidemia, hypertension, obesity, current smoking, and family history of premature cardiovascular disease (CVD). Values are reported as mean (±SD), median (interquartile range) or percentages.

Results

From 417 premature CAD patients, 112 (26.9%) had T2D at the time of presentation with CAD. In 27 (24.1%) patients, T2D was newly diagnosed at presentation with CAD. Age of diagnosis of T2D was 41.3 (±6.9) years old. Patients with T2D had higher prevalence of dyslipidemia (83.0% vs 63.3%, p&lt;0.001), hypertension (65.2% vs 40.3%, p&lt;0.001), and obesity (56.3% vs 34.8%, p&lt;0.001), higher cumulative number of CVRFs per person (2.8 (±1.2) vs 2.0 (±1.2), p&lt;0.001) and less favourable lipid profiles, with higher levels of triglycerides (3.3 (2.1–4.7) vs 2.3 (1.5–3.4) mmol/L, p=0.001) and lower HDL-cholesterol (0.9 (±0.3) vs 1.1 (±0.3) mmol/L). Prevalence of smoking (32.1% vs 24.9%, p=0.14) and family history of premature CVD (43.8% vs 39.7%, p=0.45), levels of LDL-cholesterol (3.7 (±1.4) vs 3.8 (±1.2) mmol/L, p=0.23) and lipoprotein(a) (206 (99–819) vs 200 (99–700) mg/L, p=0.57) were not significantly different between groups. T2D patients had a greater prevalence of 3-vessel disease (35.7% vs. 22.2%, p=0.006) and were less likely to receive revascularization (70.5% vs 83.9%, p=0.002).

Prior to presentation with CAD, 31 (27.7%) of T2D patients received insulin, 42 (37.5%) received oral hypoglycemic drugs, and 12 (10.7%) received no pharmacological treatment for diabetes. Only 23 (27.1%) of them achieved HbA1C ≤7% at the time of presentation with CAD (Figure 1). Among all T2D patients, 35 (31.3%) received treatment with statins and 16 (14.3%) reached guideline-recommended lipid targets of LDL cholesterol ≤2 mmol/L and/or non-HDL cholesterol ≤2.6 mmol/L.

Conclusion

Among patients with very premature CAD, T2D was common, was previously unrecognized in up to one quarter, and was associated with a greater burden of CVRFs and more extensive CAD at presentation. Few patients with T2D achieved guideline-recommended lipid or glucose targets. These data point to the need for improvements in screening and comprehensive CVRF treatment of T2D in order to reduce the burden of premature CAD.

HESRi potential for action

Resolution on Health Equity (EUR/RC69/R5) puts equity, gender equality, human rights and social determinants as high priority for action of all 53 WHO EURO Member States (MS) and partners. The resolution was unanimously adopted following a year of extensive consultation and dialogue with MS and partners: NGOs, scientific community, professional associations and UN and bilateral agencies. WHO scientific leadership role in health equity in EURO was key to success as it brought forward innovations in health equity analysis and solutions which were also presented and debated at the high-level regional conference. Together with member states WHO is now developing Health Equity Solutions Platform to connect innovative life policy sites with the latest available evidence and practical tools to accelerate development of solutions. New narrative, set of tools and innovative methodology in data analysis were taken up globally, represent a model for the global report on health inequities and feed into global strategy on social determinants of health.

Hermeneutic phenomenological human science research method in clinical practice settings: An integrative literature review

Researchers conduct phenomenological studies to better understand the experiences of phenomena. Researchers conducting phenomenological studies use different research methods grounded in philosophical underpinnings. Van Manen's hermeneutic phenomenological human science method is used in understanding phenomena in diverse disciplines. The purpose of the integrative review was to explore and synthesize research to address two questions about the human science method in clinical practice settings. Wittemore and Knafi (2005)'s method for integrative review was used to explore current literature and summarize the use of human science method. A database search of keywords in peer-reviewed articles published from 2009 to 2019 was reviewed. Eleven key research studies were selected for the integrative literature review. The key studies met the inclusion criteria of phenomenology, nurses, human science method, clinical practice, and van Manen. Researchers used van Manen's human science method as guidelines for collecting and analyzing data about the lived experience of diverse phenomena in clinical practice settings. An understanding of the human science method will guide researchers who conduct research studies using van Manen's approach to phenomenology.

Surgical training rotation design: effects of hospital type, rotation theme and duration

BACKGROUND

Entrants into UK surgical specialty training undertake a 2-year programme of core surgical training, rotating through specialties for varying lengths of time, at different hospitals, to gain breadth of experience. This study aimed to assess whether these variables influenced core surgical trainee (CST) work productivity.

METHODS

Intercollegiate Surgical Curriculum Programme portfolios of consecutive CSTs between 2016 and 2019 were examined. Primary outcome measures were workplace-based assessment (WBA) completion, operative experience and academic outputs (presentations to learned societies, publications and audits).

RESULTS

A total of 344 rotations by 111 CSTs were included. Incremental increases in attainment were observed related to the duration of core surgical training rotation. The median number of consultant-validated WBAs completed during core surgical training were 48 (range 0-189), 54 (10-120) and 75 (6-94) during rotations consisting of 4-, 6- and 12-month posts respectively (P < 0·001). Corresponding median operative caseloads (as primary surgeon) were 84 (range 3-357), 110 (44-394) and 134 (56-366) (P < 0·001) and presentations to learned societies 0 (0-12), 0 (0-14) and 1 (0-5) (P = 0·012) respectively. Hospital type and specialty training theme were unrelated to workplace productivity. Multivariable analysis identified length of hospital rotation as the only factor independently associated with total WBA count (P = 0·001), completion of audit (P = 0·015) and delivery of presentation (P = 0·001) targets.

CONCLUSION

Longer rotations with a single educational supervisor, in one training centre, are associated with better workplace productivity. Consideration should be given to this when reconfiguring training programmes within the arena of workforce planning.

Sarcopenia and myosteatosis in patients undergoing curative radiotherapy for head and neck cancer: Impact on survival, treatment completion, hospital admission and cost

BACKGROUND

Computed tomography (CT) is the gold standard of body composition analysis at the tissue-organ level. The present study aimed to determine the impact of CT-defined sarcopenia and myosteatosis on outcomes, including overall survival, unplanned hospital admissions and related costs, in patients who had completed treatment of curative intent for head and neck cancer (HNC).

METHODS

Retrospective observational study of patients undergoing radiotherapy of curative intent ± other treatment modalities for HNC. Tissue density data derived at the third lumbar vertebra (L3) were evaluated with sarcopenia defined per sex-specific published threshold values for skeletal muscle index, stratified by body mass index and mean skeletal muscle attenuation in HU (Hounsfield units).

RESULTS

Pre- or post-treatment images were available for 79/98 patients (80.6%) and 61/98 patients (62.2%), respectively. Sarcopenia was present in 42/79 patients pre-treatment and 36/61 patients post-treatment, whereas myosteatosis was present in 63/79 patients pre-treatment and 48/61 patients post-treatment. In patients with pre- and post-treatment images (n = 60), the median (range) percentage weight change was -8.5% (-29.9 to +11.7). On multivariable analysis, a post-treatment sarcopenia hazard ratio of 3.87 (95% confidence interval = 1.22-12.24, P = 0.021) and a pre-treatment myosteatosis hazard ratio of 8.86 (95% confidence interval = 1.12-69.88, P = 0.038) were independent predictors of reduced overall survival. There was no difference in radiotherapy or chemotherapy treatment completion based on pre-treatment sarcopenia status. The mean (SD) difference unplanned hospital admission cost was $15 846 ($17 707) for patients without sarcopenia versus $47 945 ($82 688) for patients with sarcopenia at any time point (P = 0.077).

CONCLUSIONS

As CT-defined sarcopenia and myosteatosis hold clinically meaningful prognostic value, muscle status evaluation is recommended in routine clinical practice.

Variation in training requirements within general surgery: comparison of 23 countries

Background

Many differences exist in postgraduate surgical training programmes worldwide. The aim of this study was to provide an overview of the training requirements in general surgery across 23 different countries.

Methods

A collaborator affiliated with each country collected data from the country's official training body website, where possible. The information collected included: management, teaching, academic and operative competencies, mandatory courses, years of postgraduate training (inclusive of intern years), working‐hours regulations, selection process into training and formal examination.

Results

Countries included were Australia, Belgium, Canada, Colombia, Denmark, Germany, Greece, Guatemala, India, Ireland, Italy, Kuwait, the Netherlands, New Zealand, Russia, Saudi Arabia, South Africa, South Korea, Sweden, Switzerland, UK, USA and Zambia. Frameworks for defining the outcomes of surgical training have been defined nationally in some countries, with some similarities to those in the UK and Ireland. However, some training programmes remain heterogeneous with regional variation, including those in many European countries. Some countries outline minimum operative case requirement (range 60–1600), mandatory courses, or operative, academic or management competencies. The length of postgraduate training ranges from 4 to 10 years. The maximum hours worked per week ranges from 38 to 88 h, but with no limit in some countries.

Conclusion

Countries have specific and often differing requirements of their medical profession. Equivalence in training is granted on political agreements, not healthcare need or competencies acquired during training.

The value of peer support for self-management of diabetes among veterans in the Empowering Patients In Chronic care intervention

AIM

To examine the value of peer support in the self-management of diabetes among veterans in an integrated health care system.

METHODS

We conducted semi-structured in-depth interviews with veterans and clinicians 6 months after their participation in Empowering Patients in Chronic Care (EPIC), a group-based diabetes intervention with a peer-support component. Interviews elicited clinicians' narratives of how peer support unfolded in the groups and veterans' experiences of giving and receiving support from their peers. Data analysis was guided by principles of framework analysis using Heisler's peer-support model.

RESULTS

Findings support Heisler's peer-support model and provide evidence supporting professional-led group visits with peer exchange. Clinicians and veterans endorsed informational and emotional support received in EPIC groups. Clinicians often referred to EPIC as an open forum or a support group where veterans could both give and receive help. Veterans noted the benefits of shared problem-solving and the support they received. Clinicians and veterans perceived the peer-support component of EPIC as facilitating increased empowerment in terms of self-efficacy, increased perceived social support and increased understanding of self-care. Ultimately, many veterans acknowledged that their participation in EPIC facilitated improved health-related quality of life, improved health behaviours and improved chronic disease control.

CONCLUSIONS

Findings emphasize the value of peer support in managing chronic illness. Peer-support programmes may address veterans' unique challenges and have the potential to improve physical and mental health.

Tools and approaches towards sustainable investment for health equity

Issue

The drive to deliver better results for the economy and for society is challenged by the daily pressures faced by policy makers to contain the public expenditure while delivering improved outcomes. This is evident also in the health sector where costs are perceived to be spiralling. As a result, the sector faces huge pressure to cut budget and services. On the other hand, the health sector is a minor contributor towards health equity, as social, economic and environmental determinants of health are mostly responsibility of other sectors. Health equity and well-being are outcomes of societal values, culture and policy choices, that create the conditions for prosperous lives for all, leaving no one behind.

Description

There are different approaches and tools that can be used for advocating, planning and monitoring investments for health equity. To name a few that the health system can introduce: mainstreaming equity into health services, employment, procurement and purchasing practices for better social and economic benefits; Health Equity Impact Assessment that supports implementation of Health Equity in All Policies and Agenda 2030; voluntary national review reporting on SDGs - all stressing the need for disaggregation of data, new evidence and methods, and monitoring.

Results/Lessons

Health equity is a complex issue that needs comprehensive response combining various approaches and tools in advocating, planning, implementing and monitoring. Besides situation analysis, more and more WHO Member States are requesting evidence about what works and how to do it. Therefore, tailor made assessment, solution development and monitoring is becoming a standard. This needs to be supported with continuous training and capacity building. WHO European Office for Investment for Health and Development developed a Health Equity Status Report and a flagship course on Equity in Health in All Policies, built on the latest evidence and tailored to country / community needs.

Cross-sectional study of the prevalence, causes and management of hospital-onset diarrhoea

BACKGROUND

The National Health Service in England advises hospitals collect data on hospital-onset diarrhoea (HOD). Contemporaneous data on HOD are lacking.

AIM

To investigate prevalence, aetiology and management of HOD on medical, surgical and elderly-care wards.

METHODS

A cross-sectional study in a volunteer sample of UK hospitals, which collected data on one winter and one summer day in 2016. Patients admitted ≥72 h were screened for HOD (definition: ≥2 episodes of Bristol Stool Type 5-7 the day before the study, with diarrhoea onset >48 h after admission). Data on HOD aetiology and management were collected prospectively.

FINDINGS

Data were collected on 141 wards in 32 hospitals (16 acute, 16 teaching). Point-prevalence of HOD was 4.5% (230/5142 patients; 95% confidence interval (CI) 3.9-5.0%). Teaching hospital HOD prevalence (5.9%, 95% CI 5.1-6.9%) was twice that of acute hospitals (2.8%, 95% CI 2.1-3.5%; odds ratio 2.2, 95% CI 1.7-3.0). At least one potential cause was identified in 222/230 patients (97%): 107 (47%) had a relevant underlying condition, 125 (54%) were taking antimicrobials, and 195 (85%) other medication known to cause diarrhoea. Nine of 75 tested patients were Clostridium difficile toxin positive (4%). Eighty (35%) patients had a documented medical assessment of diarrhoea. Documentation of HOD in medical notes correlated with testing for C. difficile (78% of those tested vs 38% not tested, P<0.001). One-hundred and forty-four (63%) patients were not isolated following diarrhoea onset.

CONCLUSION

HOD is a prevalent symptom affecting thousands of patients across the UK health system each day. Most patients had multiple potential causes of HOD, mainly iatrogenic, but only a third had medical assessment. Most were not tested for C. difficile and were not isolated.

The Pellegrini-Stieda Lesion of the Knee: An Anatomical and Radiological Review

The Pellegrini-Stieda lesion is a calcification on the medial side of the knee. The origin of this tissue is controversial. The purpose of our study is to investigate the origin of the Pellegrini-Stieda lesion using conventional radiography as to recreate the circumstances in which Pellegrini and Stieda had to study this pathology. Six nonpaired fresh-frozen cadaveric knees were used. A surgical approach to the medial side of the knee was performed using the layered approach. The origin of the gastrocnemius muscle (GM) (n = 3) or the superficial medial collateral ligament (sMCL) (n = 3) were marked with a radio-opaque fluid. X-ray analysis was performed by measuring the distance from the proximal part of the marking to the medial tibial plateau, multilayer views, and comparison to the original X-rays by Pellegrini-Stieda. Two out of three markings in both the GM and sMCL group were matched with the correct structure. The images were digitally processed so that the osseous structures became partly transparent. After overlaying the images, we found a random distribution of the markings. The Stieda/GM group had no overlap of the markings at all. Compared with the original images from the publications by Pellegrini and Stieda, no comparable position could be found between the original lesions and the markings in our specimens. Conventional X-ray of the knee could not reproduce a distinction between the sMCL and GM as origins for the Pellegrini-Stieda lesion as suggested by Pellegrini and Stieda.

Pattern of failure in anaplastic glioma patients with an IDH1/2 mutation

PURPOSE

The current study aimed to assess patterns of failure (PoF) in anaplastic glioma (AG) patients managed with intensity-modulated radiation therapy (IMRT) and their relationship to molecular subtype.

METHODS

The outcomes of AG patients managed between 2008 and 2014 and entered into a prospective database were assessed, including PoF. AG was initially defined using the WHO 2007 classification, but for analysis, patients were subsequently recategorised based on WHO 2016 as anaplastic oligodendroglioma (AOD), astrocytoma isocitrate dehydrogenase (IDH) mutant (AAmut) or astrocytoma IDH wildtype (AAwt). Management involved IMRT and temozolomide (TMZ), including from 2011 patients with an IDH mutation (IDHmut) planned with 18F-fluoroethyltyrosine (FET) and 18F-fluorodeoxyglucose (FDG) positron-emission tomography (PET). PoF was local, marginal or distant in relation to the IMRT volume. Relapse-free survival (RFS) was calculated from the start of IMRT.

RESULTS

A total of 156 patients were assessed, with median follow-up of 5.1 years. Of these patients, 75% were IDHmut, 44% were managed at first or later relapse and 73% received TMZ. Relapse occurred in 68 patients, with 6‑year RFS of 75.0, 48.8 and 2.5% for AOD, AAmut and AAwt, respectively (p < 0.001). There was a component of local relapse in 63%, of marginal relapse in 19% and of distant relapse in 37% of relapses. Isolated local, marginal and distant relapse was evident in 51, 9 and 22%, respectively. A distant relapse pattern was more frequent in IDHmut compared to IDHwt patients (26% vs. 45%, p = 0.005), especially within the first 2 years post-IMRT. In multivariate analysis, distant relapse remained associated with AAmut (p < 0.002) and delayed IMRT until the second relapse (p < 0.001).

CONCLUSION

Although patients with IDH-mutated AG have improved outcomes, there was a higher proportion of distant relapses occurring during the 2 years after IMRT.
