Identifying the unmet supportive care needs of individuals affected by testicular cancer: a systematic review. J Cancer Surviv 2024; 18:263-287. [PMID: 35781623 PMCID: PMC10960773 DOI: 10.1007/s11764-022-01219-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 05/19/2022] [Indexed: 10/17/2022]
Abstract
PURPOSE To critically appraise studies to identify experiences of unmet supportive care needs of individuals affected by testicular cancer. METHODS A registered priori systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. CINAHL, PsycINFO, and MEDLINE were searched for quantitative, qualitative, and mixed methods studies using a wide range of search terms. All articles were double screened according to a pre-determined eligibility criterion. Reference lists of the final included studies were checked for further eligible studies. The review process was managed using Covidence systematic review software. Data from the studies were extracted, methodological quality appraisal conducted, and a narrative synthesis conducted. RESULTS Of the 72 papers identified, 36 studies were included. In descending order of frequency of need, psychological needs were identified in 26/36, physical needs 18/36, interpersonal/intimacy needs 19/36, health system/information needs 11/36, cognitive needs 9/36, social needs 7/36, and of equal frequencies counts of 4/36 for family, practical, and patient-clinician information needs. Only one study explored spiritual needs and no daily living needs were identified. CONCLUSIONS The experience of needs varied in terms of frequency and distress which were commonly influenced by the age of the individual across the cancer care continuum persisting after 1-year post-treatment. IMPLICATIONS FOR CANCER SURVIVORS When caring for individuals affected by testicular cancer, clinicians are encouraged to take a holistic lens to cancer care, particularly to explore issue or concerns that young men affected by testicular cancer might be embarrassed or reticent to discuss.

Current data processing methods and reporting standards for untargeted analysis of volatile organic compounds using direct mass spectrometry: a systematic review. Metabolomics 2024; 20:42. [PMID: 38491298 PMCID: PMC10942920 DOI: 10.1007/s11306-024-02104-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 02/16/2024] [Indexed: 03/18/2024]
Abstract
INTRODUCTION Untargeted direct mass spectrometric analysis of volatile organic compounds has many potential applications across fields such as healthcare and food safety. However, robust data processing protocols must be employed to ensure that research is replicable and practical applications can be realised. User-friendly data processing and statistical tools are becoming increasingly available; however, the use of these tools have neither been analysed, nor are they necessarily suited for every data type. OBJECTIVES This review aims to analyse data processing and analytic workflows currently in use and examine whether methodological reporting is sufficient to enable replication. METHODS Studies identified from Web of Science and Scopus databases were systematically examined against the inclusion criteria. The experimental, data processing, and data analysis workflows were reviewed for the relevant studies. RESULTS From 459 studies identified from the databases, a total of 110 met the inclusion criteria. Very few papers provided enough detail to allow all aspects of the methodology to be replicated accurately, with only three meeting previous guidelines for reporting experimental methods. A wide range of data processing methods were used, with only eight papers (7.3%) employing a largely similar workflow where direct comparability was achievable. CONCLUSIONS Standardised workflows and reporting systems need to be developed to ensure research in this area is replicable, comparable, and held to a high standard. Thus, allowing the wide-ranging potential applications to be realised.

Hosing of a Long Relativistic Particle Bunch in Plasma. PHYSICAL REVIEW LETTERS 2024; 132:075001. [PMID: 38427892 DOI: 10.1103/physrevlett.132.075001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 01/16/2024] [Indexed: 03/03/2024]
Abstract
Experimental results show that hosing of a long particle bunch in plasma can be induced by wakefields driven by a short, misaligned preceding bunch. Hosing develops in the plane of misalignment, self-modulation in the perpendicular plane, at frequencies close to the plasma electron frequency, and are reproducible. Development of hosing depends on misalignment direction, its growth on misalignment extent and on proton bunch charge. Results have the main characteristics of a theoretical model, are relevant to other plasma-based accelerators and represent the first characterization of hosing.

The development of the Belgian paediatric clinical trial network. Acta Clin Belg 2024; 79:34-45. [PMID: 38054741 DOI: 10.1080/17843286.2023.2283664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 11/10/2023] [Indexed: 12/07/2023]
Abstract
Paediatric clinical trials are critical to ensure that medications prescribed to children are safe and effective. However, evidence-based dosing and labelling of such medications remain limited, and most clinical trials in paediatrics fail. Factors for lack of trial completion include performance at site level (limited patient recruitment, limited site staff experience and lack of infrastructure), the sponsor team (limited paediatric specific expertise in design, uncertainties on robustness of biomarkers or outcome variables) as well as regulatory and administrative burdens. As a result of the growing demand for site support, the Belgian Paediatric Clinical Research Network (BPCRN) established in 2009 has been relaunched in 2018 to improve paediatric clinical trials, with the support of innovative-medicines-initiative 2 (IMI2) pan-European network conect4children (c4c) and the transatlantic network I-ACT for Children (US).This paper highlights the formation of the BPCRN and the practical insights it offers for advancing paediatric clinical trials through national networks. A national network can improve trial quality, safety and efficiency, provide clinical research expertise, identify suitable sites, and help with troubleshooting of common trial issues. The BPCRN's centralized approach has advanced paediatric clinical trials by streamlining communication and standardizing trial conduct. Challenges and opportunities have arisen, including a relaunch in 2018, orphan medicine trials, and network sustainability. Collaboration between network activities, government support, site-level improvements, efficient communication, and interaction with industry are key to achieve lasting transformation in paediatric medicine research.

Barriers and facilitators associated with the implementation of surgical safety checklists: A qualitative systematic review. J Adv Nurs 2024; 80:465-483. [PMID: 37675871 DOI: 10.1111/jan.15841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 08/07/2023] [Accepted: 08/23/2023] [Indexed: 09/08/2023]
Abstract
AIM Despite the documented benefits of the World Health Organisation Patient Safety Checklist compliance rates with implementation continue to cause risk to patient safety. This qualitative systematic review aimed to explore the reported factors that impact compliance and implementation processes related to surgical safety checklists in perioperative settings. DESIGN A qualitative systematic review. METHODS A systematic review using the Joanna Briggs Institute (JBI) approach to synthesize qualitative studies was conducted and reported according to PRISMA guidelines. Electronic databases were expansively searched using keywords and subject headings. Articles were assessed using a pre-selected eligibility criterion. Data extraction and quality appraisal was undertaken for all included studies and a meta-aggregation performed. DATA SOURCES The CINAHL, Medline and Scopus databases were searched in August 2022 and the search was repeated in June 2023. RESULTS 34 studies were included. Following the synthesis of the findings there were multiple interrelating barriers to checklist compliance that impacted implementation. There were more barriers than enablers reported in existing studies. Enablers included effective leadership, education and training, timely use of audit and feedback, local champions, and the option for local modifications to the surgical checklist. Further research should focus on targeted interventions that improve observed compliance rates to optimize patient safety. CONCLUSION This qualitative systematic review identified multiple key factors that influenced the uptake of the Surgical Safety Checklist in operating theatres. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE Surgeon participation, hierarchical culture, complacency, and duplication of existing safety processes were identified which impacted the use and completion of the checklist.

Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial. Lancet Diabetes Endocrinol 2024; 12:39-50. [PMID: 38061371 PMCID: PMC7615591 DOI: 10.1016/s2213-8587(23)00321-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

To understand the experiences, needs, and preferences for supportive care, among children and adolescents (0-19 years) diagnosed with cancer: a systematic review of qualitative studies. J Cancer Surviv 2023:10.1007/s11764-023-01508-9. [PMID: 38151586 DOI: 10.1007/s11764-023-01508-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 11/27/2023] [Indexed: 12/29/2023]
Abstract
PURPOSE This study aimed to understand the experiences, needs, and preferences for supportive care, among children and adolescents (0-19 years) diagnosed with cancer. METHODS A qualitative systematic review has been reported according to PRISMA guidelines. A comprehensive search was conducted across multiple databases (APA PsycINFO, CINAHL, and Medline) and citation searches. Studies were screened according to pre-determined inclusion and exclusion criteria. Methodological quality was evaluated. Findings were extracted in relation to the context of interest of experiences, needs, and preferences of supportive care. Each finding was accompanied by a qualitative verbatim illustration representing the participant's voice. RESULTS 4449 publications were screened, and 44 studies were included. Cancer populations represented in the included studies included lymphoma, leukaemia, brain cancer, sarcomas, and neuroblastoma. Two overarching synthesised findings were identified as (1) coping, caring relationships, communication, and impact of the clinical environment, and (2) experiences of isolation, fear of the unknown, restricted information, and changing self. Children and adolescents articulated that cancer care would be enhanced by developing a sense of control over their body and healthcare, being involved in communication and shared decision-making, and ensuring the clinical environment is age-appropriate. Many experienced a sense of disconnection from the rest of the world (including peers, school, and experiences of prejudice and bullying), and a lack of tailored support and information were identified as key unmet care needs that require further intervention. CONCLUSIONS Children and adolescent who are diagnosed with cancer are a unique and understudied group in oncological survivorship research, with the slowest progress in improvement of care over time. This review will facilitate the development of future interventions and promote the importance of tailored support for children and adolescents at all stages of the cancer journey. IMPLICATIONS FOR CANCER SURVIVORS Children and adolescents continue to experience a range of difficulties despite routine contact with cancer healthcare professionals. Children and adolescents should be carefully assessed about their individual circumstances and preferences for support given the clear implications from this review that "one size" does not fit all.

Identifying experiences of supportive care of children and young people affected by kidney failure: A qualitative systematic review. J Ren Care 2023. [PMID: 38116998 DOI: 10.1111/jorc.12484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Revised: 11/03/2023] [Accepted: 11/19/2023] [Indexed: 12/21/2023]
Abstract
BACKGROUND Children and young people affected by kidney failure experience complexities in their care. Little is known about the unique needs of this young patient population group living with a long-term condition. OBJECTIVE A meta-aggregation of all qualitative studies was conducted to identify experiences of supportive care among children and young people living with kidney failure. METHODS A systematic review of qualitative studies was conducted following the Joanna Briggs Institute meta-aggregation method. This review has been reported according to the PRISMA statement guidelines. Six electronic databases (CINAHL, Cochrane Library, MEDLINE, Proquest, PsycINFO, and Scopus) were comprehensively searched by an expert systematic review librarian using keywords and subject headings, from inception to September 2022. All studies were accessed using a predetermined inclusion and exclusion criteria. Methodological quality assessment and data extraction performed. Qualitative findings accompanied by illustrative quotes from included studies were extracted and grouped into categories which created the overall synthesised findings. RESULTS A total of 34 studies were included in this review representing a total of 613 children and young people affected by kidney failure. There was a total of 190 findings which created 13 categories representing experiences of supportive care. The meta-aggregation developed five synthesised findings namely: 'physical needs', 'information and technology', 'treatment and healthcare', 'social needs' and 'psychological impacts'. CONCLUSION This systematic review identified that children and young people affected by kidney failure can experience a range of unmet supportive care needs in routine clinical services. Kidney failure impacted children and young people's self-identify, social and peer networks, introduced daily practical needs because of inherent physical and psychological burden due to the failure and associated treatments. Despite improvements in the medical management of kidney failure in children and young people, further attention is needed to optimise supported self-management in this young patient group.

Abstract
OBJECTIVE To critically synthesize and describe the use and methods of ecological momentary assessment (EMA) in cancer research. DATA SOURCES A systematic review was conducted and has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Guideline. Electronic databases (APA PsycINFO, CINAHL, Cochrane Central Register of Controlled Trials, MEDLINE, Scopus, and Web of Science Core Collection) were searched using a variety of keywords and subject headings by an expert systematic review librarian. All publications were double screened by two reviewers using predetermined exclusion and inclusion criteria throughout the full review process. The review used Covidence Systematic Review Software. Methodological quality assessment and data extraction were performed. A narrative synthesis was conducted to examine the aim for EMA, the characteristics of the study samples, the EMA sampling procedures, EMA completion rates, outcome measures, and any implications of findings for survivorship care. CONCLUSION A total of 42 EMA studies in cancer were included. Most studies used an electronic mobile device to capture EMA data apart from several that used paper diaries. Existing studies were found to have significant heterogeneity in methods and widely varying approaches to design and self-report measurements. While EMA in cancer research holds significant promise to advance cancer care research into the future by increasing ecological validity and reducing retrospective bias and can capture the unique idiographic within-person change over time, in real-time, further research is needed to develop standardized EMA self-report questionnaires. IMPLICATIONS FOR NURSING PRACTICE This is the first comprehensive systematic review to describe the use and methods of EMA in cancer research. There is significant heterogeneity in methods and widely varying approaches to design and self-report measurements in EMA cancer research. People affected by cancer found taking part in EMA studies reported benefit from the experience. However, researchers must engage with cancer survivors in the development and co-design of future EMA questionnaires to ensure relevant and acceptability of EMA data collection protocols.

Abstract
OBJECTIVE The term "scanxiety" has been coined to describe the anxiety commonly associated with individuals undergoing cancer-related imaging. Despite the prevalence and severity of scanxiety across various clinical and demographic populations, there remains a significant lack of qualitative insights from existing studies that effectively capture patients' experiences of scanxiety in their own words. Therefore, this review addresses the following research question: What are the experiences of scanxiety distress among people affected by cancer across the cancer care continuum? DATA SOURCES Following the PRISMA methodology, a meta-aggregation of qualitative studies was performed, encompassing patients of all age groups who had been diagnosed with cancer or were indicated for a cancer-related scan. Of the 556 articles screened, 15 were deemed eligible for inclusion in the analysis. CONCLUSION The three overarching themes of 1) experience of "scan-itis," 2) experience of "patient-clinician support," and 3) development of self-management strategies reveal the complex and interconnected factors that influence scanxiety in individuals undergoing cancer-related imaging. These findings emphasized distress experienced by patients during the waiting period for scan results, the act of viewing the results, and even the delivery of "bad" news. Consequently, patients expressed a strong desire for increased information, communication, and empathy from attending healthcare providers. Patients also report a myriad of self-coping strategies to manage their scanxiety well before, during, and after their scan appointment. IMPLICATIONS FOR NURSING PRACTICE The study highlights the need for targeted interventions for those undergoing cancer-related scans, including increased awareness and education for health professionals regarding scanxiety.

What are the holistic care impacts among individuals living through the COVID-19 pandemic in residential or community care settings? An integrative systematic review. Int J Older People Nurs 2023; 18:e12557.

Abstract
INTRODUCTION To critically synthesise evidence in relation to the holistic care impacts (physical, psychological, social, spiritual, and environmental well-being) among individuals living in residential aged care facilities (RACFs) with restrictions during the COVID-19 pandemic. METHODS An integrative systematic review followed a pre-registered protocol and has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Guidelines. Electronic databases were searched from inception to June 2022. Qualitative, quantitative, and mixed methods studies were included. All articles were double screened according to a pre-determined eligibility criterion. The review process was managed using Covidence systematic review software. Data from the studies were extracted, methodological quality appraisal conducted, and a narrative synthesis conducted. RESULTS 18 studies were included. The impact of restrictive practices and periods of lockdown impacted older people on all levels of individual quality-of-life. With or without COVID-19, residents experienced functional decline and many experienced malnutrition, increased incontinence, increased pain, and poorer general health and significant psychological distress. Depression increased with reduced social contact, as did anxiety and loneliness. Some residents spoke of suicidal ideation. CONCLUSION It is highly plausible that further outbreaks may prompt knee-jerk reactions from public health departments and governing bodies to continue to restrict and lockdown facilities. Public health COVID-19 outbreak policy for aged care across the globe will need to consider the benefits verses risk debate given the findings uncovered in this review. These findings showed that it is vital that policy considers quality-of-life domains not solely survival rates.

Qualitative findings accompanied by illustrative quotes from included studies were extracted and grouped into categories, which created the overall synthesised findings. RESULTS A total of 33 studies were included which represented a total sample of 671 participants inclusive of 303 patients and 368 informal caregivers. There was a total of 220 individual findings included in this review, which were synthesised into two findings (1) caregivers and patients perceived supports which would have been helpful and (2) caregiver and patient experiences of unmet supportive care needs. CONCLUSION This review highlighted the suffering and distress caused by brain cancer and associated treatments. Both patients and their informal caregivers experienced disconnect from themselves in renegotiating roles, and a profound sense of loneliness as the physical deterioration of the disease progressed. Both patients and informal caregivers reported similar unmet needs within the current service provision for brain cancer. However, what is apparent is that current cancer services are provided solely for patients, with little or no consideration to the support needs of both the patient and their informal caregiver. Service re-design is needed to improve care coordination with individualised informational support, implementation of holistic needs assessments for both the patients and their caregivers, better community support provision, improved opportunities for emotional care with early referral for palliative care services. IMPLICATIONS FOR CANCER SURVIVORS It is recommended that members of the multidisciplinary brain cancer team reflect on these findings to target holistic needs assessments and develop shared self-management care plans for both the patient and the informal caregiver.

We analyze JUNE: a detailed model of COVID-19 transmission with high spatial and demographic resolution, developed as part of the RAMP initiative. JUNE requires substantial computational resources to evaluate, making model calibration and general uncertainty analysis extremely challenging. We describe and employ the uncertainty quantification approaches of Bayes linear emulation and history matching to mimic JUNE and to perform a global parameter search, hence identifying regions of parameter space that produce acceptable matches to observed data, and demonstrating the capability of such methods.

Abstract
Abstract
Introduction
Surgeon assessment of visual ‘quality of perfusion’ (QOP) influences kidney discard and predicts transplant outcome. However, this assessment is subjective and bias-prone.
We aimed to design an application utilising a smartphone camera to make this assessment objective and enhance decision making.
Methods
The QOP in photographs of backbench kidneys was graded from 1 (ideal) to 5 (very poor) by three independent surgeons. A training cohort was used to develop an image-analysis algorithm, which was validated in a separate cohort.
Results
Analysing surgeon scores of 174 kidney images revealed that inter-rater agreement was good for kidneys displaying the best (rated 1) and worst (rated 4 or 5) QOP. However, for intermediate scores inter-rater agreement was poor. Inter-rater agreement between surgeons decreased as they graded more images; as surgeons fatigued, their ability to classify images worsened. A training cohort (n=174 kidneys) was used for algorithm development. First, small regions within each image were mapped within the CEILAB colour-space, where well-perfused and poorly perfused areas show clear separation. To generate a score for each kidney these regions are compared with ideally flushed kidney tissue. Testing our algorithm (validation cohort - n=29 kidneys) revealed strong correlation between image-analysis QOP score and surgeon assessment, r=0.789 (0.587–0.899), P<0.001.
Conclusion
Surgeon inter-rater agreement on kidney QOP is low for kidneys with borderline QOP and worsens with fatigue. We provide a QOP score utilising an image-analysis algorithm, which correlates with surgeon scoring. With additional images and training this could provide an objective, numerical, point-of-care assessment of organ quality.
Take-home message
Current visual assessment of transplant organ quality is subjective and bias-prone. This body of work attempts to create a point-of-care image-analysis application to provide an objective numeric organ quality score.

Abstract
INTRODUCTION A combination of punitive sentencing practices within ageing populations, compounded by the health challenges faced by people in prison, means that dedicated palliative care provision within prisons is a pressing requirement. However, evidence about exactly how quality palliative and end-of-life care is delivered in this environment remains sparse.This review aims to develop a typology of models of palliative and end-of-life care delivery within prisons in high-income countries to inform service development and policy. METHODS AND ANALYSIS We will conduct a scoping review of published studies and grey literature, following the Arksey and O'Malley framework. We will report data on models of palliative and end-of-life care delivery in prisons in high-income countries. Searches will be undertaken in Medline, EMBASE, CINAHL, Social Sciences Citation Index and PsyINFO for all study types, published from 1 January 2000 to December 2021, and reference lists from key reviews and studies will be screened for additional references. We will also screen grey literature from within other high-income countries using a targeted search strategy. For published reports of original research, study quality and risk of bias will be assessed independently by two reviewers using the Mixed Methods Appraisal Tool. A narrative synthesis of the data will be undertaken, integrating the results of the quality assessment. ETHICS AND DISSEMINATION Approval by research ethics committee is not required since the review only includes published and publicly accessible data. We will publish our findings in a peer-reviewed journal as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidance. PROTOCOL REGISTRATION The final protocol was registered with the Research Registry on 26 November 2021 (www.researchregistry.com).Unique ID number: reviewregistry1260.

Abstract
Listening to, and acting on, the voices of children and families during clinical research and innovation is fundamental to ensuring enhanced pediatric health care, medicines development, and technological advances. While this is often discussed as an important step in ensuring patient-centered care, involving children and families across the life cycle of clinical research is not currently routine. The pediatric research community needs to address how to meaningfully involve children and families if they are to succeed in designing clinical research that suits the needs of pediatric patients and their families. This paper describes how an international community working under the umbrella International Children’s Advisory Network (iCAN) and European Young Person’s Advisory Group Network (eYPAGnet) has involved children and families in the design and delivery of pediatric clinical research. It offers practical solutions through various case studies assessed against seven patient engagement quality criteria within the Patient Engagement Quality Guidance (PEQG) tool, highlighting some of the lessons learnt from involving and engaging with children and families across different stages of clinical research, including pediatric trials for drug development programs.

Abstract
Abstract
Clinical trials are often perceived as being expensive, difficult and beyond the capacity of academic groups and healthcare workers in low-resource settings. However, in order to improve healthcare coverage, the WHO World Health Report 2013 stated that all countries need to become generators as well as recipients of data. This study is a methodological examination of the steps and processes involved in setting up the Gojjam Lymphoedema Best Practice Trial (GoLBeT; ISRCTN67805210), a highly pragmatic clinical trial conducted in northern Ethiopia. Challenges to the trial and strategies used to deal with them were explored, together with reasons for delays. A qualitative approach using the Global Health Research Process Map as a framework was used to analyse emails and reports from the period between trial inception and recruitment. This analysis was complemented by interviews with key informants from the operational team and a group discussion. This study showed that the key areas of difficulty in setting up and planning this trial were: the study design (definition and measurement of the study endpoint, and assuring statistical power); recruitment and appropriate training of staff; planning for data quality; and gaining regulatory approvals. Collaboration was essential to successfully setting up the trial. Other important aspects were a team and process perspective, staff training, community engagement, and data quality e.g., through data management. Lessons learnt from this trial might guide in planning pragmatic trials in settings where research is not common, allowing researchers to anticipate challenges and address them through trial design, planning and operational delivery. We also hope that this example might encourage similar pragmatic studies to be undertaken. Such studies are rarely undertaken or locally led, but are an accessible and efficient way to drive improved outcomes in public health.
Key messages
Pragmatic clinical trials are essential to drive improved outcomes in public health in low-resource settings, but are perceived as challenging to set up and initiate. Our analysis of the Gojjam Lymphoedema Best Practice Trial found that factors for a successful set-up were collaborations, a team perspective, staff training, community engagement and data management.

Abstract
Abstract
Background
Medical education should equip students with the necessary skills to support the diverse population they treat and work with and be confident to act as an ally for patients and colleagues. We found there to be a gap for a diversity module in the curriculum at Oxford University.
Method
We created a diversity training session for over 300 medical students aiming to;
The course consisted of a series of talks conducted by a senior lecturer on diversity, doctors, patients, and students, followed by small-group case-based teaching facilitated by a final-year medical student and a junior doctor. All facilitators underwent training by a senior lecturer on diversity. The cases encouraged students to reflect on their own personal biases and enact how they would confront discrimination on the wards. Students completed a survey before and after the session, rating self-confidence on six key learning points.
Results
91.4% students agreed the session was useful to their medical training. There was a significant increase in students who felt confident implementing all learning points: defining key terms (post-session: 95.4%, pre-session: 82.3%); understanding health inequalities (post-session: 93%, pre-session: 54.6%); awareness of personal bias (post-session: 87.9%, pre-session: 70%); partaking in allyship (post-session: 95%, pre-session: 89.5%); and being an active bystander (post-session: 91.4%, pre-session: 45.9%). 79.3% felt confident to challenge acts of discrimination (33.6% pre-session).
Conclusions
This session educates and empowers students to challenge acts of discrimination. We recommend the implementation of similar sessions at all medical schools.

Abstract
We present the Core Imaging Library (CIL), an open-source Python framework for tomographic imaging with particular emphasis on reconstruction of challenging datasets. Conventional filtered back-projection reconstruction tends to be insufficient for highly noisy, incomplete, non-standard or multi-channel data arising for example in dynamic, spectral and in situ tomography. CIL provides an extensive modular optimization framework for prototyping reconstruction methods including sparsity and total variation regularization, as well as tools for loading, preprocessing and visualizing tomographic data. The capabilities of CIL are demonstrated on a synchrotron example dataset and three challenging cases spanning golden-ratio neutron tomography, cone-beam X-ray laminography and positron emission tomography.

Abstract
OBJECTIVE To evaluate health care fragmentation in patients with stage II and III rectal cancers. BACKGROUND Fragmentation of care among multiple hospitals may worsen outcomes for cancer patients. METHODS National Cancer Database was queried for adult patients who underwent radiation and surgery for locally advanced (stage II-III) rectal adenocarcinoma from 2006 to 2015. Fragmented care was defined as receiving radiation at a different hospital from surgery. Descriptive statistics characterized patients, and survival probability was plotted using the Kaplan-Meier method and a Cox proportional hazards model. RESULTS A total of 37,081 patients underwent surgery and radiation for stage II-III rectal cancer from 2006 to 2015 (24,102 integrated care vs. 12,979 fragmented care). Patients who received fragmented care (hazard ratio [HR] 1.105; 95% CI 1.045-1.169) had a higher risk of mortality. Patients who received at least surgery (HR 0.84; 95% CI 0.77-0.92) at academic hospitals had a lower risk of mortality. Academic hospitals had a higher proportion of patients with fragmented care (38.0 vs. comprehensive community 32.8% vs. community 33.8%, p < 0.001). Within academic hospitals, fragmented care portended worse survival (integrated academic 80.0% vs. fragmented academic 76.7%, p = 0.0002). Fragmented care at academic hospitals had increased survival over integrated care at community hospitals (fragmented academic 76.7 vs. integrated community 72.2%, p = 0.00039). CONCLUSIONS In patients with stage II-III rectal cancer, patients who have integrated care at academic hospitals or at least surgery at academic centers had better survival. All efforts should be made to reduce care fragmentation and surgery at academic centers should be prioritized.

Abstract
We use a relativistic ionization front to provide various initial transverse wakefield amplitudes for the self-modulation of a long proton bunch in plasma. We show experimentally that, with sufficient initial amplitude [≥(4.1±0.4) MV/m], the phase of the modulation along the bunch is reproducible from event to event, with 3%-7% (of 2π) rms variations all along the bunch. The phase is not reproducible for lower initial amplitudes. We observe the transition between these two regimes. Phase reproducibility is essential for deterministic external injection of particles to be accelerated.

Abstract
RAC1 activity is critical for intestinal homeostasis, and is required for hyperproliferation driven by loss of the tumour suppressor gene Apc in the murine intestine. To avoid the impact of direct targeting upon homeostasis, we reasoned that indirect targeting of RAC1 via RAC-GEFs might be effective. Transcriptional profiling of Apc deficient intestinal tissue identified Vav3 and Tiam1 as key targets. Deletion of these indicated that while TIAM1 deficiency could suppress Apc-driven hyperproliferation, it had no impact upon tumourigenesis, while VAV3 deficiency had no effect. Intriguingly, deletion of either gene resulted in upregulation of Vav2, with subsequent targeting of all three (Vav2-/- Vav3-/- Tiam1-/-), profoundly suppressing hyperproliferation, tumourigenesis and RAC1 activity, without impacting normal homeostasis. Critically, the observed RAC-GEF dependency was negated by oncogenic KRAS mutation. Together, these data demonstrate that while targeting RAC-GEF molecules may have therapeutic impact at early stages, this benefit may be lost in late stage disease.

Abstract
We study experimentally the effect of linear plasma density gradients on the self-modulation of a 400 GeV proton bunch. Results show that a positive or negative gradient increases or decreases the number of microbunches and the relative charge per microbunch observed after 10 m of plasma. The measured modulation frequency also increases or decreases. With the largest positive gradient we observe two frequencies in the modulation power spectrum. Results are consistent with changes in wakefields' phase velocity due to plasma density gradients adding to the slow wakefields' phase velocity during self-modulation growth predicted by linear theory.

Abstract
PURPOSE To systematically evaluate evidence regarding the unmet supportive care needs of men and women affected by chemotherapy-induced alopecia (CIA) to inform clinical practice guidelines. METHODS We performed a review of CINAHL, MEDLINE, PsychINFO, Scopus, the Cochrane Library (CCRT and CDSR) controlled trial databases and clinicaltrials.gov from January 1990 to June 2019 according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Twenty-seven publications were selected for inclusion in this analysis. RESULTS Included reports used qualitative (ten) and quantitative (17) studies. Across these studies men and women reported the major impact that CIA had on their psychological well-being, quality of life and body image. Hair loss had a negative impact irrespective of gender, which resulted in feelings of vulnerability and visibility of being a "cancer patient". Men and women described negative feelings, often similar, related to CIA with a range of unmet supportive care needs. CONCLUSIONS Some patients are not well-prepared for alopecia due to a lack of information and resources to reduce the psychological burden associated with CIA. Hair loss will affect each patient and their family differently, therefore, intervention and support must be tailored at an individual level of need to optimise psychological and physical well-being and recovery. IMPLICATIONS FOR CANCER SURVIVORS People affected by CIA may experience a range of unmet supportive care needs, and oncology doctors and nurses are urged to use these findings in their everyday consultations to ensure effective, person-centred care and timely intervention to minimise the sequalae associated with CIA.

Abstract
OBJECTIVES Fetal growth restriction (FGR) is associated with maternal cardiovascular changes. Sildenafil, a phosphodiesterase type-5 inhibitor, potentiates the actions of nitric oxide, and it has been suggested that it alters maternal hemodynamics, potentially improving placental perfusion. Recently, the Dutch STRIDER trial was stopped prematurely owing to excess neonatal mortality secondary to pulmonary hypertension. The main aim of this study was to investigate the effect of sildenafil on maternal hemodynamics in pregnancies with severe early-onset FGR. METHODS This was a cardiovascular substudy within a UK multicenter, placebo-controlled trial, in which 135 women with a singleton pregnancy and severe early-onset FGR (defined as a combination of estimated fetal weight or abdominal circumference below the 10th centile and absent/reversed end-diastolic flow in the umbilical artery on Doppler velocimetry, diagnosed between 22 + 0 and 29 + 6 weeks' gestation) were assigned randomly to receive either 25 mg sildenafil three times daily or placebo until 32 + 0 weeks' gestation or delivery. Maternal blood pressure (BP), heart rate (HR), augmentation index, pulse wave velocity (PWV), cardiac output, stroke volume (SV) and total peripheral resistance were recorded before randomization, 1-2 h and 48-72 h post-randomization, and 24-48 h postnatally. For continuous data, analysis was performed using repeated measures ANOVA methods including terms for timepoint, treatment allocation and their interaction. RESULTS Included were 134 women assigned randomly to sildenafil (n = 69) or placebo (n = 65) who had maternal BP and HR recorded at baseline. At 1-2 h post-randomization, compared with baseline values, sildenafil increased maternal HR by 4 bpm more than did placebo (mean difference, 5.00 bpm (95% CI, 1.00-12.00 bpm) vs 1.25 bpm (95% CI, -5.38 to 7.88 bpm); P = 0.004) and reduced systolic BP by 1 mmHg more (mean difference, -4.13 mmHg (95% CI, -9.94 to 1.44 mmHg) vs -2.75 mmHg (95% CI, -7.50 to 5.25 mmHg); P = 0.048). Even after adjusting for maternal mean arterial pressure, sildenafil reduced aortic PWV by 0.60 m/s more than did placebo (mean difference, -0.90 m/s (95% CI, -1.31 to -0.51 m/s) vs -0.26 m/s (95% CI, -0.75 to 0.59 m/s); P = 0.001). Sildenafil was associated with a non-significantly greater decrease in SV index after 1-2 h post-randomization than was placebo (mean difference, -5.50 mL/m2 (95% CI, -11.00 to -0.50 mL/m2 ) vs 0.00 mL/m2 (95% CI, -5.00 to 4.00 mL/m2 ); P = 0.056). CONCLUSIONS Sildenafil in a dose of 25 mg three times daily increases HR, reduces BP and reduces arterial stiffness in pregnancies complicated by severe early-onset FGR. These changes are short term, modest and consistent with the anticipated vasodilatory effect. They have no short- or long-term clinical impact on the mother. Copyright © 2019 ISUOG.

Abstract
Abstract
Background
Tetralogy of Fallot with pulmonary artesia (PA-VSD) complete repair includes the placement of a right ventricle to pulmonary artery conduit. As more and more patients survive past childhood, the need for conduit replacement has increased. Transcatheter pulmonary valve implantation (TPVI) has emerged as an alternative to the surgical pulmonary valve replacement (SPVR) in conduit failure, but comparative data are lacking.
Purpose
We aim to use data from a national procedural audit database to compare TPVI and SPVR in operated PA-VSD with conduit failure.
Method
All patients with surgically corrected PA-VSD undergoing TPVI or SPVR between 2006–2012 were included (SPVR n=103, TPVI n=31). A propensity score matching algorithm based on age, gender, known genetic mutations, MAPCAs presence of endocarditis, preoperative mechanical support, operation year and follow-up time was used and resulted in balanced groups.
Results
Median age at TPVI and SPVR were 23 years (11–51) and 12 years (0.3–55) respectively. Median follow-up was 3.7 years (1 day-12.5 years) in SPVR and 2 years (0.3–10.6) in TPVI. There were slightly more females in the TPVI group (64% vs 49% in SPVR p=0.1). There were no significant differences in procedure era (77% after 2005), MAPCAs (31%) or known genetic conditions (17%). All cases of preoperative endocarditis (n=6) and mechanical support (n=4) were in the SPVR group.
Survival, freedom from pulmonary valve replacement (PVR) and PVR free survival before and after matching at 5 years are shown in Table. After matching survival tended to be lower in TPVI (p=0.4), but without reaching statistical significance, while freedom from PVR (p=0.004, Figure) and PVR free survival (0.02) were significantly lower after TPVI, compared to SPVR.
Relative mortality by age increments Before matching After matching TPVI SPVR TPVI SPVR p value Survival at 5 years (%) 87 92 87 94 0.4 Freedom from PVR at 5 years (%) 83 96 83 100 0.004 PVR free survival at 5 years (%) 72 88 72 94 0.02
Conclusions
In our study TPVI showed comparable midterm survivable with SPVR, but significantly lower freedom from PVR, resulting in a lower PVR free survival. Further studies with longer follow-up and a prospective design are needed to investigate the factors influencing these outcomes.

Abstract
In this article, we briefly summarize the experiments performed during the first run of the Advanced Wakefield Experiment, AWAKE, at CERN (European Organization for Nuclear Research). The final goal of AWAKE Run 1 (2013-2018) was to demonstrate that 10-20 MeV electrons can be accelerated to GeV energies in a plasma wakefield driven by a highly relativistic self-modulated proton bunch. We describe the experiment, outline the measurement concept and present first results. Last, we outline our plans for the future. This article is part of the Theo Murphy meeting issue 'Directions in particle beam-driven plasma wakefield acceleration'.

Abstract
OBJECTIVES This study aimed to understand what information the US media communicated about Zika virus (ZIKV) and travel in 2016 and 2017. STUDY DESIGN We conducted a content analysis of news coverage about ZIKV and travel from April 5, 2016 to March 31, 2017. METHODS We obtained a stratified, random sample of English language, US print newspaper and television news coverage about ZIKV and travel. We developed a coding scheme to assess key messages in the news, including how ZIKV is transmitted, the symptoms and outcomes of ZIKV infection, and recommended prevention behaviors. RESULTS Almost all news stories mentioned mosquito-borne transmission (96.8%) and just over half mentioned sexual transmission (55.3%). News stories were more likely to talk about ZIKV outcomes (78.8%) than ZIKV symptoms (40.6%). However, outcomes affecting babies were mentioned more frequently than outcomes affecting adults. Recommendations included a wide array of protective behaviors, such as delaying or avoiding travel (77.6%) and using mosquito repellent (41.0%). However, few studies (10.9%) mentioned barriers to practicing ZIKV prevention behaviors. CONCLUSIONS Public health organizations and professionals can use these findings to help improve communication about future outbreaks of mosquito-borne illnesses. We also recommend conducting real-time monitoring of news media and frequent content analysis of news stories to ensure coverage provides the information the public needs.

Experimental Observation of Proton Bunch Modulation in a Plasma at Varying Plasma Densities. PHYSICAL REVIEW LETTERS 2019; 122:054802.

Abstract
We give direct experimental evidence for the observation of the full transverse self-modulation of a long, relativistic proton bunch propagating through a dense plasma. The bunch exits the plasma with a periodic density modulation resulting from radial wakefield effects. We show that the modulation is seeded by a relativistic ionization front created using an intense laser pulse copropagating with the proton bunch. The modulation extends over the length of the proton bunch following the seed point. By varying the plasma density over one order of magnitude, we show that the modulation frequency scales with the expected dependence on the plasma density, i.e., it is equal to the plasma frequency, as expected from theory.

Experimental Observation of Plasma Wakefield Growth Driven by the Seeded Self-Modulation of a Proton Bunch. PHYSICAL REVIEW LETTERS 2019; 122:054801.

Abstract
We measure the effects of transverse wakefields driven by a relativistic proton bunch in plasma with densities of 2.1×10^{14} and 7.7×10^{14} electrons/cm^{3}. We show that these wakefields periodically defocus the proton bunch itself, consistently with the development of the seeded self-modulation process. We show that the defocusing increases both along the bunch and along the plasma by using time resolved and time-integrated measurements of the proton bunch transverse distribution. We evaluate the transverse wakefield amplitudes and show that they exceed their seed value (<15 MV/m) and reach over 300 MV/m. All these results confirm the development of the seeded self-modulation process, a necessary condition for external injection of low energy and acceleration of electrons to multi-GeV energy levels.

With widespread adoption of MIS colectomy for colon cancer, does hospital type matter? Surg Endosc 2019; 33:159-168.

Abstract
BACKGROUND Recent studies have shown that hospital type impacts patient outcomes, but no studies have examined hospital differences in outcomes for patients undergoing minimally invasive surgery (MIS) for segmental colectomies. METHODS The 2010-2014 National Cancer Data Base was queried for patients undergoing segmental colectomy for non-metastatic colon adenocarcinoma. Descriptive statistics characterized MIS utilization by hospital type. Multivariable models were used to examine the effect of hospital type on outcomes after MIS. Survival probability was plotted using the Kaplan-Meier method. RESULTS 80,922 patients underwent MIS segmental colectomy for colon cancer from 2010 to 2014. From 2010 to 2014, the number of MIS segmental colectomies increased by 157% at academic hospitals, 151% at comprehensive hospitals, and 153% at community hospitals. Compared to academic hospitals, community and comprehensive hospitals had greater adjusted odds of positive margins (Community OR 1.525, 95% Confidence Interval 1.233-1.885; Comprehensive OR 1.216, 95% CI 1.041-1.42), incomplete number of lymph nodes analyzed (< 12 LNs) from surgery (Community OR 2.15, 95% CI 1.98-2.32; Comprehensive OR 1.42, 95% CI 1.34-1.51), and greater 30-day mortality (Community OR 1.43, 95% CI 1.14-1.78; Comprehensive OR 1.36, 95% CI 1.17-1.59). Patient survival probability was higher at academic hospitals at 5 years (Academic 69% vs. Comprehensive 66% vs. Community 63%, p < 0.001). Community hospitals and comprehensive hospitals had significantly higher risk of adjusted long-term mortality (Community HR 1.28; 95% CI 1.19-1.37; p < 0.001; Comprehensive HR 1.14; 95% CI 1.09-1.20; p < 0.001). CONCLUSIONS Despite widespread use of laparoscopic oncologic surgery, short- and long-term outcomes from MIS for segmental colectomy are superior at academic hospitals. This difference may be due to superior perioperative oncologic technique and surgical outcomes at academic hospitals. Our data provide important information for patients, referring physicians, and surgeons about the significance of hospital type in management of colon cancer.

Critical care usage after major gastrointestinal and liver surgery: a prospective, multicentre observational study. Br J Anaesth 2019; 122:42-50.

Abstract
BACKGROUND Patient selection for critical care admission must balance patient safety with optimal resource allocation. This study aimed to determine the relationship between critical care admission, and postoperative mortality after abdominal surgery. METHODS This prespecified secondary analysis of a multicentre, prospective, observational study included consecutive patients enrolled in the DISCOVER study from UK and Republic of Ireland undergoing major gastrointestinal and liver surgery between October and December 2014. The primary outcome was 30-day mortality. Multivariate logistic regression was used to explore associations between critical care admission (planned and unplanned) and mortality, and inter-centre variation in critical care admission after emergency laparotomy. RESULTS Of 4529 patients included, 37.8% (n=1713) underwent planned critical care admissions from theatre. Some 3.1% (n=86/2816) admitted to ward-level care subsequently underwent unplanned critical care admission. Overall 30-day mortality was 2.9% (n=133/4519), and the risk-adjusted association between 30-day mortality and critical care admission was higher in unplanned [odds ratio (OR): 8.65, 95% confidence interval (CI): 3.51-19.97) than planned admissions (OR: 2.32, 95% CI: 1.43-3.85). Some 26.7% of patients (n=1210/4529) underwent emergency laparotomies. After adjustment, 49.3% (95% CI: 46.8-51.9%, P<0.001) were predicted to have planned critical care admissions, with 7% (n=10/145) of centres outside the 95% CI. CONCLUSIONS After risk adjustment, no 30-day survival benefit was identified for either planned or unplanned postoperative admissions to critical care within this cohort. This likely represents appropriate admission of the highest-risk patients. Planned admissions in selected, intermediate-risk patients may present a strategy to mitigate the risk of unplanned admission. Substantial inter-centre variation exists in planned critical care admissions after emergency laparotomies.

Abstract
OBJECTIVE To determine the effectiveness and economic impact of two methods for induction of labour in hypertensive women, in low-resource settings. DESIGN Cost-consequence analysis of a previously reported multicentre, parallel, open-label randomised trial. SETTING & POPULATION A total of 602 women with a live fetus, aged ≥18 years requiring delivery for pre-eclampsia or hypertension, in two public hospitals in Nagpur, India. METHODS We performed a formal economic evaluation alongside the INFORM clinical trial. Women were randomised to receive transcervical Foley catheterisation or oral misoprostol 25 mcg. Healthcare expenditure was calculated using a provider-side microcosting approach. MAIN OUTCOME MEASURES Rates of vaginal this delivery within 24 hours of induction, healthcare expenditure per completed treatment episode. RESULTS Induction with oral misoprostol resulted in a (mean difference) $20.6USD reduction in healthcare expenditure [95% CI (-) $123.59 (-) $72.49], and improved achievement of vaginal delivery within 24 hours of induction, mean difference 10% [95% CI (-2 to 17.9%), P = 0.016]. Oxytocin administration time was reduced by 135.3 minutes [95% CI (84.4-186.2 minutes), P < 0.01] and caesarean sections by 9.1% [95% CI (1.1-17%), P = 0.025] for those receiving oral misoprostol. Following probabilistic sensitivity analysis, oral misoprostol was cost-saving in 63% of 5,000 bootstrap replications and achieved superior rates of vaginal delivery, delivery within 24 hours of induction and vaginal delivery within 24 hours of induction in 98.7%, 90.7%, and 99.4% of bootstrap simulations. Based on univariate threshold analysis, the unit price of oral misoprostol 25 mcg could feasibly increase 31-fold from $0.24 to $7.50 per 25 mcg tablet and remain cost-saving. CONCLUSION Compared to Foley catheterisation for the induction of high-risk hypertensive women, oral misoprostol improves rates of vaginal delivery within 24 hours of induction and may also reduce costs. Additional research performed in other low-resource settings is required to determine their relative cost-effectiveness. TWEETABLE ABSTRACT Oral misoprostol less costly and more effective than Foley catheter for labour induction in hypertension.

Abstract
Ureteric herniation into the inguinal canal is a rare condition in adults and even more so in the paediatric population. These hernia types can be categorised as paraperitoneal or extraperitoneal. The former are the only varieties encountered in the paediatric literature, where patients are generally infants, while the latter phenomenon is seen in 20% of ureteric herniations in adults. We present a case of an extraperitoneal ureteric herniation into the inguinal canal in a 12-year-old boy with previous surgery for cloacal exstrophy, analyse the existing literature on the condition and make the speculation that the extraperitoneal variety is an adult variant seen in this child because of weakness in the surrounding structures as a result of previous surgery.
