Understanding improved neonatal ventilation trends in a regional transport service

AIM

Review changes in neonatal ventilation practice within our regional transport service, Embrace, identifying interventions with greatest impact on improved rates of normocapnia during transfer.

METHODS

Using internal transport databases and UK Neonatal Transport Group data submissions, we tracked local and national rates of ventilation and normocapnia. We correlated this with internal changes in practice, including introduction of new equipment, staffing changes, educational interventions and quality improvement projects.

RESULTS

Data demonstrated improvement in normocapnia rates benchmarked against national figures, which was not explained by changes in ventilation methods or rates, or by changes in availability of post-transfer gases. Greatest improvement was identified following introduction of transcutaneous CO2 monitoring and ventilators enabling volume-guided ventilation strategies. Additionally, although less quantifiable, educational and quality improvement interventions, and case review mechanisms were felt to be influential.

CONCLUSION

Volume guided ventilation and transcutaneous CO2 monitoring have had a positive influence on the maintenance of normocapnia during transfer at Embrace Transport Service, although introduction of new equipment still presents challenges which must be overcome. Recognising the significant impact of these technologies allows for ongoing financial, time and educational investment to emphasise their importance and ensure appropriate awareness of limitations and troubleshooting options, maximising their positive impact.

Chromothripsis orchestrates leukemic transformation in blast phase MPN through targetable amplification of DYRK1A

Chromothripsis, the process of catastrophic shattering and haphazard repair of chromosomes, is a common event in cancer. Whether chromothripsis might constitute an actionable molecular event amenable to therapeutic targeting remains an open question. We describe recurrent chromothripsis of chromosome 21 in a subset of patients in blast phase of a myeloproliferative neoplasm (BP-MPN), which alongside other structural variants leads to amplification of a region of chromosome 21 in ∼25% of patients ('chr21amp'). We report that chr21amp BP-MPN has a particularly aggressive and treatment-resistant phenotype. The chr21amp event is highly clonal and present throughout the hematopoietic hierarchy. DYRK1A , a serine threonine kinase and transcription factor, is the only gene in the 2.7Mb minimally amplified region which showed both increased expression and chromatin accessibility compared to non-chr21amp BP-MPN controls. We demonstrate that DYRK1A is a central node at the nexus of multiple cellular functions critical for BP-MPN development, including DNA repair, STAT signalling and BCL2 overexpression. DYRK1A is essential for BP-MPN cell proliferation in vitro and in vivo , and DYRK1A inhibition synergises with BCL2 targeting to induce BP-MPN cell apoptosis. Collectively, these findings define the chr21amp event as a prognostic biomarker in BP-MPN and link chromothripsis to a druggable target.

Outcomes of skin cancer excision in frail patients: A retrospective cohort study

BACKGROUND

Non-melanoma skin cancer (NMSC) is the most common cancer type and incidence increases with age. As a consequence, an increasing number of frail patients are being referred for consideration of skin cancer surgery. However, some of these patients may not live long enough to experience benefit from surgery, while being at risk of postoperative complications.

OBJECTIVES

To investigate the treatment burden of surgical excision of skin cancers in frail individuals.

METHODS

We conducted a single-center retrospective cohort study analyzing outcomes of skin cancer excision in frail versus non-frail patients.

RESULTS

Eighty-eight patients were included. The complication rate was higher in frail versus non-frail patients: 12 (27.9%) versus 9 (18.8%), with 5 unplanned postoperative hospital attendances leading to 3 hospital admissions in the frail cohort. Nine patients in the frail group (21%) died within 6 months of their procedure versus no deaths in the non-frail group (p < 0.001 Fisher's Exact test), with no deaths attributed to skin cancer.

CONCLUSION

Treatment-related complications and mortality are common in frail patients after surgical excision of skin lesions clinically suspicious for skin cancer. Careful consideration should be given, and patients should be adequately counseled about treatment risks and alternative management options, including active surveillance, in particular, if the lesions are expected to remain asymptomatic.

Qualitative evaluation of the acceptability and feasibility among healthcare professionals and patients of an ART multi-cycle treatment planning and continuation intervention prototype

STUDY QUESTION

Is it possible to design an ART Treatment Planning and Continuation Intervention (TPCI) that is considered acceptable and feasible to patients and healthcare professionals (HCPs)?

SUMMARY ANSWER

HCPs and patients responded positively to the TPCI prototype and perceived it as an acceptable intervention to support patients to stay engaged with planned treatment, but some concerns were raised about the feasibility of using it in practice.

WHAT IS KNOWN ALREADY

People discontinue ART due to its psychological burden. Digital tools to support people undergoing ART are available but typically focus only on practical support rather than psychological support. Research about treatment continuation and multi-cycle planning indicates that cognitive factors (expectations, intentions, efficacy beliefs) should be targets of interventions designed to help patients engage with and continue treatment to meet their personal treatment plans and goals. However, it is not known whether this form of psychological support would be acceptable for HCPs and patients or feasible to implement in practice.

STUDY DESIGN, SIZE, DURATION

Qualitative cognitive interviews with HCPs and patients (May 2021). Patients were eligible if they had had a consultation to start a first/repeat stimulated IVF/ICSI cycle in the 8 weeks prior to recruitment, were aged 18 or older (upper age limit of 42 years for women) and fluent in English. Eligible HCPs were those employed by a fertility clinic who were responsible for delivering treatment planning consultations to patients.

PARTICIPANTS/MATERIALS, SETTING, METHODS

HCPs and patients were asked to think aloud while being exposed to and exploring the TPCI in one-to-one online cognitive interviews. The TPCI was designed to reduce treatment discontinuation via cognitive factors namely formation and maintenance of multi-cycle ART intentions and efficiency of decision-making during treatment, and continuation of treatment after an unsuccessful cycle (when recommended). To impact cognitive factors the TPCI comprised of two components: an expectation management and reasoning checklist for HCPs to use during planning consultations (TPCI Checklist) and a multi-feature cognitive support mobile application (TPCI App) for patients to use prior to and during treatment. After participants thought aloud while being exposed to the TPCI prototype (both components) they were asked open questions concerning their perceptions of the core components and activities on eight acceptability dimensions (e.g. acceptability, demand, integration). Interviews lasted between 40 and 90 min, were recorded, transcribed verbatim and analysed using thematic analysis.

MAIN RESULTS AND THE ROLE OF CHANCE

Thirteen HCPs and 13 patients participated in 25 online interviews. Thematic analysis using inductive and deductive coding generated 180 codes, grouped into 22 categories and synthesized into 9 themes. The themes showed that HCPs and patients provided positive feedback about the TPCI, perceiving it as a needed, acceptable and potentially effective way to forewarn patients of the possible need for multiple cycles, to provide patients with a sense of patient-clinic collaboration and support, and to bolster treatment intentions, all of which were perceived to contribute to reduced treatment discontinuation. HCPs perceived implementation of the TPCI Checklist to be challenging in its current length due to time pressures and clinic workload. Suggestions for enhancing the TPCI Checklist and App were provided, but none required critical changes to its core components or activities.

LIMITATIONS, REASONS FOR CAUTION

All patients were women recruited from social media websites, mainly associated with patient support groups, who may be highly committed to their fertility treatment. HCPs were predominantly from private fertility clinics.

WIDER IMPLICATIONS OF THE FINDINGS

The findings suggest there is demand for digital support geared towards motivational aspects of undergoing ART. The TPCI is an acceptable support tool to meet that need according to HCPs responsible for delivering planning consultations and patients undergoing fertility treatment. Future research is needed to develop the prototype and examine the feasibility of implementation of the TPCI in clinics.

Comorbidity patterns in older patients with diabetes in primary care: a cross-sectional study

Funding Acknowledgements

Type of funding sources: None.

Background

Diabetes is a well-known risk factor for cardiovascular diseases and continues to be a global public health challenge. In Australia, prevalence rates of diabetes increase with age with almost 1 in 5 older people reported being diagnosed with diabetes. Older persons with diabetes are also more likely to have multiple comorbidities adding to their complexity. A better understanding of comorbidity patterns and their associated factors in older people with diabetes is instrumental to identify groups of individuals that differ in healthcare needs, resources utilized, and health trajectories.

Purpose

To identify comorbidity patterns in community-dwelling older adults with type 2 diabetes attending general practice settings in Australia.

Methods

This is a cross-sectional study based on the Bettering the Evaluation And Care of Health (BEACH) data. The BEACH program was a continuous, national study of the state of general practice clinical activity in Australia from 1998 to 2016. As part of the program, General Practitioners (GPs) would collect additional patient information during patient visits through structured paper-based recording sheets. For the purposes of this sub-study, a random sample of 1800 participating GPs were invited to record all diagnosed chronic conditions for 30 consecutive patients over twelve five-weeks recording periods between November 2012 and March 2016. The dataset was analyzed with descriptive analysis and exploratory factor analyses were applied to examine comorbidity patterns.

Result

From the dataset, there were 14 042 patients aged ≥65 with recorded chronic conditions. Of these, 2688 reported to have other comorbidities in addition to the diagnosis of diabetes. Hypertension was present in 67.33% (95% CI: 64.62 – 70.04) of these participants, followed by hyperlipidemia, 44.85% (95% CI: 41.80 –47.90), ischemic heart disease, 22.81% (95% CI: 20.74 – 24.87), atrial fibrillation, 10.25% (95% CI: 8.86 – 11.63), congestive heart failure, 7.03% (95% CI: 5.99 – 8.09), stroke/cerebrovascular accident, 6.76% (95% CI:5.36 -8.16) and peripheral vascular disease 5.26% (4.36 – 6.15). Top non-cardiovascular co-morbidities included arthritis, 51.78% (95% CI: 48.80–54.77) and depression, 15.52% (95% CI 13.78 –17.27). We identified two comorbidity patterns among older people with diabetes. The first were primarily psychological and musculoskeletal (Depression, Anxiety, Insomnia, Chronic Back Pain, Arthritis, Gastroesophageal Reflux Disease, Osteoporosis) and the second were cardiovascular conditions (Congestive Heart Failure, Ischaemic Heart Disease, Atrial Fibrillation, Peripheral Vascular Disease) and Chronic Renal Failure.

Conclusion

The prevalence of cardiovascular and non-cardiovascular comorbidities in older patients with diabetes was high. These findings highlight the need for elaborating primary care strategies to reduce cardiovascular risk and improve long-term care for this population.

O045 A systematic review of observational management of cutaneous basal cell carcinoma

Background

Cutaneous basal cell carcinoma (BCC) is the commonest cancer in the United Kingdom. Surgical excision is the most common treatment. This review summarises all published outcomes of observational/non-interventional management of BCC.

Methods

This PRISMA-compliant systematic review searched MEDLINE, EMBASE and CENTRAL databases from inception-June 2021. All studies reporting outcomes of observational management for BCC were included.

Results

From 2529 titles, four full-text articles reporting on 2298 individuals were eligible. Two studies were randomised controlled trials (RCTs) comparing histological clearance rates and adverse events following treatment with an inactive strategy (placebo cream) versus topical 5%-imiquimod (at different frequencies) for 6–12 weeks. Clearance rates ranged from 52–100% for imiquimod and 2–19% for placebo, with more adverse events associated with imiquimod. The other two studies used prospective cohort designs. One study assessed the natural history of BCCs managed expectantly in 39 individuals aged ≥80years. During the 15.8-month follow-up, 46.2% of lesions did not increase in size and 10.3% resolved. The remaining study compared treatment patterns of 1360 patients with non-melanoma skin cancer (NMSC) in individuals with or without limited life-expectancy (LLE). The LLE subgroup had a 5-year mortality rate of 43.3%, with no deaths attributed to NMSC. Only 3.3% of individuals with LLE underwent observational treatment. No study examined quality-of-life or cost-effectiveness.

Conclusion

There has been limited investigation of observational management of BCC, despite possible advantages of this strategy. Future RCTs should compare quality-of-life outcomes and utility adjusted survival following interventional or observational management of BCC.

Take-home message

This systemic review identifies a lack of data reporting outcomes following observational management of BCC, despite possible advantages of this treatment strategy. Future RCTs should compare quality of life outcomes and utility-adjusted survival following interventional or observational management of BCC.

AB0979 Recommendations for weight management in osteoarthritis: a systematic review of clinical practice guidelines

Background

Weight loss interventions are often recommended to target overweight and obesity in the clinical practice guidelines (CPGs) for the management of osteoarthritis. This is despite evidence from meta-analyses of clinical trials that significant weight loss results in modest improvements in symptoms and minimal effects on disease progression1,2. There is evidence that weight gain is associated with increase in knee pain3,4. In countries such as USA, adults gain on average 0.5 to 1 kilogram per year from early to middle adulthood Preventing weight gain is easier to achieve and sustain than losing weight.

Objectives

Given that weight loss is accepted as fundamental to osteoarthritis management, we systematically reviewed the recommendations and approaches for weight management in all current osteoarthritis CPGs.

Methods

Nine databases were searched (1st January 2010 to 30th September 2021) to identify guidelines informing the non-pharmacological management of osteoarthritis. Three reviewers appraised guidelines according to the AGREE II instrument, and independently extracted data on their characteristics. One author extracted and summarised guideline recommendations on weight management. This systematic review is registered on PROSPERO (CRD42021274195).

Results

Fifteen CPGs from developed and developing countries were included. Weight loss was recommended for knee (12 of 13 guidelines) and hip (10 of 11 guidelines) but not hand osteoarthritis (0 of 4 guidelines). Combination approaches of diet and/or exercise were recommended for overweight or obese individuals (knee: 8 of 12; hip: 4 of 10), with 2 guidelines specifying ≥5% weight loss for knee and hip osteoarthritis. One of 15 guidelines specified strategies for weight loss and maintenance of lost weight. Two of 15 guidelines recommended controlling body weight for osteoarthritis, regardless of obesity status.

Conclusion

Most CPGs for knee and hip osteoarthritis include recommendations for weight loss in those with overweight or obesity as key to managing osteoarthritis, despite evidence of modest at best effect of weight loss on symptoms and no effect on joint structure1,2. Given obesity is a major risk factors for osteoarthritis, the prevention of weight gain may be more effective and practical in improving clinical outcomes for osteoarthritis, and hence should be considered as part of the key management in osteoarthritis.

Effects of the SARS-CoV-2 pandemic on perinatal activity in Yorkshire and the Humber region during 2020: an interrupted time series analysis

OBJECTIVE

To assess the impact of public health measures taken during the COVID-19 pandemic on perinatal health indicators.

DESIGN

Interrupted time series analysis comparing periods of the pandemic with the previous 5 years.

SETTING

Yorkshire and the Humber region, England (2015-2020).

MAIN OUTCOME MEASURES

Relative risk (RR) of stillbirth, extreme preterm (EPT, <27 weeks' gestational age) delivery, hypoxic ischaemic encephalopathy (HIE) and meconium aspiration syndrome (MAS), antenatal transfer for threatened EPT delivery and postnatal transfer for EPT birth, HIE or MAS.

RESULTS

Stillbirths fell from 3.7/1000 deliveries prepandemic to 2.9/1000 afterwards; EPT births decreased from 2.5/1000 to 1.8/1000 live births. Following adjustment, during the first lockdown there were decreased antenatal transfers (RR 0.74, 95% CI 0.57 to 0.94) with non-statistically significant increased stillbirth (RR 1.08, 95% CI 0.78 to 1.51) and decreased EPT admissions (RR 0.88, 95% CI 0.60 to 1.29). Over the entire pandemic period, antenatal transfer (RR 0.64, 95% CI 0.55 to 0.76) and EPT birth (RR 0.73, 95% CI 0.56 to 0.94) decreased; stillbirths showed non-statistically significant increases overall (RR 1.21, 95% CI 0.98 to 1.49) but with increasing trend through the pandemic (RR 1.11, 95% CI 1.00 to 1.22). No changes were seen for HIE, MAS, postnatal transfers or in subgroup analyses by ethnicity.

CONCLUSIONS

Lower rates of antenatal transfer and extreme preterm birth were identified, alongside an apparent increase in stillbirth over time. The findings provide evidence that effects on perinatal activity related to the pandemic changed over time.

Managing hematological cancer patients during the COVID-19 pandemic: an ESMO-EHA Interdisciplinary Expert Consensus

BACKGROUND

The COVID-19 pandemic has created enormous challenges for the clinical management of patients with hematological malignancies (HMs), raising questions about the optimal care of this patient group.

METHODS

This consensus manuscript aims at discussing clinical evidence and providing expert advice on statements related to the management of HMs in the COVID-19 pandemic. For this purpose, an international consortium was established including a steering committee, which prepared six working packages addressing significant clinical questions from the COVID-19 diagnosis, treatment, and mitigation strategies to specific HMs management in the pandemic. During a virtual consensus meeting, including global experts and lead by the European Society for Medical Oncology and the European Hematology Association, statements were discussed and voted upon. When a consensus could not be reached, the panel revised statements to develop consensual clinical guidance.

RESULTS AND CONCLUSION

The expert panel agreed on 33 statements, reflecting a consensus, which will guide clinical decision making for patients with hematological neoplasms during the COVID-19 pandemic.

183 A Systematic Review of Sample Size Calculations in High-Profile Surgical Trials That Use Patient-Reported Outcome Measures

Background

Patient reported outcome measures (PROMs) are increasingly recognised as a measure of treatment efficacy in randomised controlled trials (RCTs). It can be difficult to determine meaningful target differences in PROM scores for sample size calculations and this can risk over-recruitment and/or erroneous trial conclusions. The Difference ELicitation in TriAls (DELTA2) statement sets recommendations for sample size calculations in RCTs including target difference determination. We aimed to evaluate sample size calculations from high-profile surgical RCTs that used PROMs as their primary outcome, against DELTA2 standards, with a focus on target differences.

Method

Pubmed was systematically searched for surgical RCTs published in the five highest ranking journals, by Thomson Reuters impact factor, for medicine and surgery. Studies were included if surgery was the intervention and/or comparator arm, and a PROM was the primary outcome. Surgery was defined as using instrumentation to change macro-anatomy with the aim of improving health. Data were extracted with a piloted data collection sheet that included the DELTA2 reporting recommendations.

Results

Most target differences used in sample size calculations were determined with suboptimal techniques and target difference justification was overall poor. In this sample, £28 million of UK public research spending supported trials with poor target difference justification.

Conclusions

In this sample of trials, sample size calculations were generally not reported to DELTA2 standards. There was frequent use of sub-optimal methods to determine the target difference. This risks over-recruitment and/or erroneous trial conclusions. Clinicians should be aware of these potential pitfalls when interpreting published trials.

Talking about possible IVF/ICSI failure and need for multiple cycles in treatment planning: qualitative investigation of multi-cycle planning and its acceptability to patients and staff

STUDY QUESTION

What are patients’ and fertility staff views of talking about possible IVF/ICSI failure and need for multiple cycles in treatment planning?

SUMMARY ANSWER

Healthcare professionals (HCPs) typically plan treatment on a cycle-by-cycle basis but HCPs and patients see benefits in talking about possible IVF/ICSI failure and the consequent need for multiple cycles to better prepare patients for this possibility, to support them through treatment challenges and to foster a sense of collaboration with the clinic in achieving the shared goal of treatment success.

WHAT IS KNOWN ALREADY

Many patients need more than one round of IVF/ICSI stimulation to achieve their parenthood goals. About 60% of patients are willing to plan for multiple cycles of treatment in advance of treatment engagement. However, it is not clear how patients are informed about the high possibility of failure and the subsequent need for multiple cycles during their treatment planning consultations, and how approaches could be optimized.

STUDY DESIGN, SIZE, DURATION

Qualitative focus groups with HCPs working at fertility clinics, patient advocates employed by patient charities (April 2020) and patients (July and August 2020). Patients were eligible if they had had a consultation to start a first/repeat stimulated IVF/ICSI cycle in the 8 weeks prior to participation, were aged 18 or older (upper age limit of 42 years for women), in heterosexual relationships and fluent in English. Eligible HCPs and patient advocates were those employed at a fertility clinic or charity, respectively.

PARTICIPANTS/MATERIALS, SETTINGS, METHOD

Focus group topic guides progressed from general questions about fertility consultations to if and how the possibility of treatment failure and need for multiple cycles was introduced and discussed in (attended/own) clinics. After, preferences regarding planning IVF/ICSI on a multi-cycle or cycle-by-cycle basis were explored. Focus groups were recorded, and recordings transcribed and analysed using framework analysis to identify shared, unique and incongruent themes across participant groups.

MAIN RESULTS AND THE ROLE OF CHANCE

Twelve HCPs, 2 patient advocates and 10 patients participated in six semi-structured online focus group discussions. All patients were childless and had been trying to conceive for ∼3 years. Framework analysis generated four themes and one meta-theme across participant groups. The meta-theme showed planning IVF on a cycle-by-cycle basis is the norm at clinics and that this affects how treatment is planned and the acceptability of a shift towards planning for multiple cycles, which was perceived as beneficial despite some apprehension. The four themes were: (i) heterogeneity in information provision during treatment planning; (ii) the need for improved HCP-patient collaboration; (iii) the need to temper optimism about treatment success; and (iv) apprehension, benefits and preferences regarding multi-cycle planning.

LIMITATIONS, REASONS FOR CAUTION

Most patients were women from private fertility clinics with no previous treatment experience recruited from social media websites, mainly associated with patient support groups. Similarly, most HCPs were women from private fertility clinics.

WIDER IMPLICATIONS OF THE FINDINGS

The findings suggest that shifting from cycle-by-cycle to multi-cycle approaches in IVF planning is possible. Achieving this shift, like other shifts in IVF (e.g. single embryo transfer), is likely to require collaboration among all stakeholders (e.g. users, staff, policymakers, regulators) to ensure that costs and benefits are balanced through using appropriate benchmarks, avoiding deflating optimism, fostering a sense of collaboration and supporting patients through challenges of multi-cycle IVF.

Sexual violence in patients with psychiatric conditions: Factors for consideration in case management

Patients with underlying psychiatric conditions are vulnerable to the experience of sexual violence. Barriers and facilitators to disclosure exist, at the level of the individual, healthcare system, legal system and society in general. Management requires a trauma-informed approach with a focus on avoidance of stigma, optimisation of pre-existing psychiatric conditions and appropriate treatment of psychological sequalae. Preventive strategies by the patient, practitioner and healthcare system, may assist to reduce the risk of future sexual violence.

1237 Optimising Outpatient Care After Paediatric Burns: The Development of a Chatbot To Identify Complications And Provide Clinical Advice

Aim

More than 6000 children require specialist care from one of fourteen regional burns services in England and Wales each year. Families often have to travel long distances and may not have access to specialist care with restricted services due to Covid-19. This quality improvement project aimed to:

Method

We conducted a national service evaluation of children’s burns services in England and Wales. We then conducted a PRISMA compliant systematic review up to September 2020 to identify studies reporting chatbot use to deliver outpatient care. A chatbot was then developed using Dialogflow to identify complications and provide advice to families.

Results

Across England and Wales, 11 children’s burns services reported outpatient practice: six services follow up all children at three months, three have variable follow-up and two discharge all patients. Our systematic review identified 10 studies reporting chatbot use although none were used following burns. A frame-based system-focused chatbot was developed in conjunction with expert burns surgeons and patient representatives.

Conclusions

Chatbots are effective and acceptable alternatives for in-person follow up. We demonstrate national variation in the provision of outpatient paediatric burn care and have developed a chatbot that can address clinical concerns and provide reassurance to patients and family members. Future studies will determine the acceptability and safety of this chatbot.

P-503 Focus groups with health care professionals, patient advocates and patients to explore how the potential need for multiple cycles is managed during fertility treatment consultations

Study question

How is possibility of failure and potential need for multiple cycles discussed with patients during the first or repeat IVF/ICSI treatment consultation?

Summary answer

Health Care Professionals plan treatment on a cycle-by-cycle basis because it is the normative way to plan treatment, but patients see advantages in multi-cycle planning

What is known already

Many patients need more than one round of IVF/ICSI stimulation to achieve their parenthood goals. A recent study has found around 60% of patients to be willing to plan for multiple cycles of treatment. However, it is not clear how patients are informed fully about the high possibility of treatment failure and the subsequent need for multiple cycles during their treatment planning consultations

Study design, size, duration

Qualitative focus groups with health care professionals (HCP) patient advocates (April 2020) and patients (July and August 2020, respectively). Patients were eligible if they had had a consultation to start a first/repeat stimulated IVF/ICSI cycle in the eight weeks prior to participation, were aged 18 or older (upper age limit of 42 years for women) and fluent in English. Eligible Health HCPs and patient advocates were those employed at a fertility clinic or charity, respectively

Participants/materials, setting, methods

HCP, patient advocate and patient focus group topic guides started with general questions about fertility consultations and progressed to discuss if and how the possibility of treatment failure and need for multiple cycles was introduced and discussed, and then preferences regarding planning IVF/ICSI on a multi-cycle rather than a single cycle basis. Focus groups were recorded, transcribed and analysed using framework analysis which allowed examination of shared, unique and incongruent thematic content across participant groups

Main results and the role of chance

Twelve HCPs, 2 patient advocates and 11 patients participated in seven semi-structured online focus group discussions. Framework analysis revealed 52 codes (e.g., possibility of failure tentatively introduced; discussion of multiple cycles dependent on clinical/patient benchmarks) abstracted into 17 higher-level categories (e.g., Failure is a sensitive topic to approach; IVF treatment failure is the norm). Synthesis of categories revealed four themes and one meta theme The meta theme showed planning treatment on a cycle-by-cycle basis was the norm. This meta-theme was supported by four themes: (1) ‘culture of communication’ that dictated benchmarks (e.g., clinic, national live birth rate) and definition of key concepts (‘complete’ cycle) that underpinned divergence between clinics; (2) ‘HCP-patient dynamics’ indexing degree of shared decision-making, advance preparation and involvement of partners in planning; (3) ‘tempering optimism’ that described tailoring, balancing and emotion management in giving personal chances of success; and (4) ‘transitioning to multi-cycle planning’ which identified worries of multi-cycle planning (e.g., need to learn from failure).

Limitations, reasons for caution

The majority of patients were women from private fertility clinics with no previous treatment experience recruited from social media websites, mainly associated with patient support groups. Similarly, the majority of HCPs were women from private fertility clinics. Informative comparisons across treatment stage, gender and funding source were therefore not possible

Wider implications of the findings

HCPs are hesitant towards multi-cycle planning. However, patients show openness, suggesting a cultural shift from the single cycle norm of planning IVF/ICSI may be possible. If adopted by clinics, HCPs patients and fertility organisations, multi-cycle planning could encourage patients to create informed treatment expectations and plans prior to treatment engagement

P–503 Focus groups with health care professionals, patient advocates and patients to explore how the potential need for multiple cycles is managed during fertility treatment consultations

Study question

How is possibility of failure and potential need for multiple cycles discussed with patients during the first or repeat IVF/ICSI treatment consultation?

Summary answer

Health Care Professionals plan treatment on a cycle-by-cycle basis because it is the normative way to plan treatment, but patients see advantages in multi-cycle planning.

What is known already

Many patients need more than one round of IVF/ICSI stimulation to achieve their parenthood goals. A recent study has found around 60% of patients to be willing to plan for multiple cycles of treatment. However, it is not clear how patients are informed fully about the high possibility of treatment failure and the subsequent need for multiple cycles during their treatment planning consultations.

Study design, size, duration

Qualitative focus groups with health care professionals (HCP) patient advocates (April 2020) and patients (July and August 2020, respectively). Patients were eligible if they had had a consultation to start a first/repeat stimulated IVF/ICSI cycle in the eight weeks prior to participation, were aged 18 or older (upper age limit of 42 years for women) and fluent in English. Eligible Health HCPs and patient advocates were those employed at a fertility clinic or charity, respectively.

Participants/materials, setting, methods

HCP, patient advocate and patient focus group topic guides started with general questions about fertility consultations and progressed to discuss if and how the possibility of treatment failure and need for multiple cycles was introduced and discussed, and then preferences regarding planning IVF/ICSI on a multi-cycle rather than a single cycle basis. Focus groups were recorded, transcribed and analysed using framework analysis which allowed examination of shared, unique and incongruent thematic content across participant groups.

Main results and the role of chance

Twelve HCPs, 2 patient advocates and 11 patients participated in seven semi-structured online focus group discussions. Framework analysis revealed 52 codes (e.g., possibility of failure tentatively introduced; discussion of multiple cycles dependent on clinical/patient benchmarks) abstracted into 17 higher-level categories (e.g., Failure is a sensitive topic to approach; IVF treatment failure is the norm). Synthesis of categories revealed four themes and one meta theme The meta theme showed planning treatment on a cycle-by-cycle basis was the norm. This meta-theme was supported by four themes: (1) ‘culture of communication’ that dictated benchmarks (e.g., clinic, national live birth rate) and definition of key concepts (’complete’ cycle) that underpinned divergence between clinics; (2) ‘HCP-patient dynamics’ indexing degree of shared decision-making, advance preparation and involvement of partners in planning; (3) ‘tempering optimism’ that described tailoring, balancing and emotion management in giving personal chances of success; and (4) ‘transitioning to multi-cycle planning’ which identified worries of multi-cycle planning (e.g., need to learn from failure).

Limitations, reasons for caution

The majority of patients were women from private fertility clinics with no previous treatment experience recruited from social media websites, mainly associated with patient support groups. Similarly, the majority of HCPs were women from private fertility clinics. Informative comparisons across treatment stage, gender and funding source were therefore not possible.

Wider implications of the findings: HCPs are hesitant towards multi-cycle planning. However, patients show openness, suggesting a cultural shift from the single cycle norm of planning IVF/ICSI may be possible. If adopted by clinics, HCPs patients and fertility organisations, multi-cycle planning could encourage patients to create informed treatment expectations and plans prior to treatment engagemen.

646 Appraisal of International Guidelines for Malignant Melanoma Management Using the AGREE II Assessment Tool

Background

Recently, the widely accepted NICE guidelines for melanoma management have been challenged by a UK-based expert consensus statement. A review of alternative clinical practice guidelines (CPGs) could guide future CPG updates and developments. The AGREE II tool assesses CPGs across six domains: ‘Scope and purpose’, ‘Stakeholder involvement’, ‘Rigour of development’, ‘Clarity of presentation’, ‘Applicability’, and ‘Editorial independence’.

Method

We conducted a systematic search of Pubmed, Medline and online CPG databases to identify melanoma CPGs published between January 2014 and March 2020 providing recommendations for: adjuvant treatment, radiotherapy, surgical management, or follow-up care. Three authors independently assessed the quality of identified CPGs using the AGREE II assessment tool. Inter-rater reliability was assessed by Kendall’s coefficient of concordance (W).

Results

Twenty-nine CPGs were included and appraised with excellent reliability (Kendall’s W for overall GPC score 0.85, p &lt; 0.001). Overall, melanoma CPGs scored highly in the scope and purpose and clarity of presentation domains, and poorly in the applicability domain. The NICE guideline achieved the best overall scores.

Conclusions

The NICE melanoma CPGs are higher quality than alternatives but should be updated to reflect recent landmark trials. The AGREE II tool is currently limited by its incapacity to compare guidelines to latest evidence.

Patient willingness, preferences and decision-making about planning for three complete cycles of IVF/ICSI treatment

STUDY QUESTION

What is willingness, preference and decision-making about planning for the possibility of needing multiple cycles of IVF/ICSI treatment among patients consulting for a first or repeat stimulated IVF/ICSI cycle?

SUMMARY ANSWER

The majority of patients seem to value the opportunity to plan for multiple cycles of treatment while acknowledging both possible challenges and benefits of doing so and decisions that might need to be made in advance.

WHAT IS KNOWN ALREADY

Patients have strong intentions to do treatment to achieve pregnancy and approximately 48-54% continue treatment when confronted with a failed cycle, undergoing at least three complete cycles of treatment. However, there is inconsistency between this apparent willingness to do multiple cycles of treatment and the way treatment is currently planned on a cycle-by-cycle basis with patients.

STUDY DESIGN, SIZE, DURATION

The study was of cross-sectional design, comprising a mixed-methods English online survey posted between November 2019 and March 2020. Eligibility criteria were being a patient who had had a consultation to start a stimulated cycle of IVF/ICSI for the first time or for a repeat stimulated cycle after an unsuccessful cycle in the eight weeks prior to survey completion. Individuals were also required to be aged 18 or older (upper age limit of 42 years for women) and able to respond in English. In total 881 clicked on the survey link, 118 did not consent, 41 were excluded after data screening, 57 did not meet the inclusion criteria, 331 started the survey but did not complete it, 28 had missing data on critical variables (e.g., age) and 306 completed the survey (40.1% completion, 57 men, 249 women).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Participants were allocated to either the willing or unwilling to plan for multiple cycles of treatment group based on their responses to three variables: willingness to plan for three complete cycles, whether they would choose to have another cycle of IVF and whether they would continue treatment after an unsuccessful cycle. Quantitative questions gathered data on preferences towards planning for multiple cycles (i.e., attitudes, subjective norms and perceived behavioural control), challenges, benefits of planning for multiple cycles, decisional conflict experienced and treatment decisions involved in planning for multiple cycles. Demographic, fertility and fertility treatment information were also collected. Qualitative questions gathered textual data on other perceived benefits and challenges of planning for multiple cycles and solutions to the challenges. Descriptive and inferential statistics were used on quantitative data. Thematic analysis (inductive coding) was performed on the textual data.

MAIN RESULTS AND THE ROLE OF CHANCE

Overall, 73.2% (n = 224) of participants had had a consultation to start a first cycle of IVF/ICSI. Participants were on average 33 years of age and had been trying to conceive for three years. A total of 63.07% (n = 193) were university educated. A total of 56% (n = 172) of participants were willing to plan for multiple cycles of IVF/ICSI in advance of treatment. Repeated measures ANOVA, t-tests and chi-square analysis showed the willing group to be significantly more likely to have been in a relationship for longer (p<.05), have higher education (p<.05) and be resident in the United Kingdom (p<.05). The willing group had positive attitudes towards planning for multiple cycles (p<.001) and stronger agreement with subjective norms (p<.001), perceived behavioural control (p<.001), benefits of planning for multiple cycles (p<.01) and felt able and attached more importance to making treatment decisions in advance of treatment (p<.05). Data saturation was achieved for the thematic analysis of textual data which revealed a total of four other challenges (e.g., less decisional freedom) and six other benefits (e.g., having a realistic view of treatment) to planning for multiple cycles. Qualitative analysis also revealed that most patients could anticipate and provide solutions for the nine challenges of planning for multiple cycles (e.g., using flexible working for the negative effect of treatment on work).

LIMITATIONS, REASONS FOR CAUTION

Limitations included the outcome measure being willingness to plan for multiple cycles rather than actual multi-cycle planning behaviour. The unwilling group represented a heterogeneous group with possibly unknown motivational coherence (e.g., definitely against planning, ambivalent about planning). Other limitations included the cross-sectional nature of the survey and the recruitment source.

WIDER IMPLICATIONS OF THE FINDINGS

Treatment consultations about undergoing fertility treatment could re-frame treatment to be a multi-cycle process in line with patient's willingness, preference and decision-making. This multi-cycle approach could empower patients and clinicians to discuss treatment expectations realistically and formulate fully informed treatment plans that take account of the high likelihood of cycle failure in addition to the treatment decisions that may need to be made during treatment when a cycle fails. This multi-cycle approach could help us support patients in adhering to their treatment plans even when faced with challenges, and help ascertain the level of treatment engagement possible to achieve parenthood goals.

Characteristics of general practitioner referrals to podiatrists in Australia, 2000-2016

OBJECTIVE

The aim of the study was to describe patterns of referral to podiatrists by general practitioners (GPs) in Australia.

STUDY DESIGN

This is a continuous cross-sectional study of Australian general practice activity.

METHODS

We analysed data from the Bettering the Evaluation and Care of Health program, collected from April 2000 to March 2016 inclusive. Data were summarised using descriptive statistics with 95% confidence intervals around point estimates. Multivariate logistic regression was used to identify GP and patient characteristics independently associated with referral.

RESULTS

The data set included 1,568,100 encounters, including 5,912 podiatry referrals. Referrals increased from 7.0 to 39.5 per 1000 population over the evaluation period. In multivariate analyses, female GPs were more likely than male GPs to refer, and GPs aged ≥55 years were less likely to refer. Patients referred to podiatrists were more likely to be aged ≥85 years, be Indigenous, be from an English-speaking background and have previously been seen at the practice. The problem generating the highest number of referrals was diabetes. After the introduction of Medicare funding, referred patients were more likely to be women, be aged >45 years, have a healthcare card, be socio-economically disadvantaged and have previously been seen at the practice.

CONCLUSIONS

GP referral to podiatrists in Australia increased markedly after the introduction of Medicare funding and appears to be targeted to those with the greatest need. Further research is required to determine whether this policy has improved outcomes and is cost-effective.

Isolation and characterization of vibriophage vB_Vc_SrVc9: an effective agent in preventing Vibrio campbellii infections in brine shrimp nauplii (Artemia franciscana)

AIMS

This study describes the physicochemical and genomic characterization of phage vB_Vc_SrVc9 and its potential for phage therapy application against a pathogenic Vibrio campbellii strain.

METHODS AND RESULTS

A lytic phage vB_Vc_SrVc9 against V. campbellii was isolated from shrimp farm sediment, and characterized physicochemical and genomically. The use of vB_Vc_SrVc9 phage increased the survival in brine shrimp Artemia franciscana and reduced presumptive V. campbellii to nondetectable numbers. Genomic analysis showed a genome with a single contig of 43·15 kb, with 49 predicted genes and no tRNAs, capable of recognizing and generating complete inhibition zones of three Vibrio sp.

CONCLUSIONS

To our knowledge vB_Vc_SrVc9 is a lytic phage that could be used against Vibrio infections, reducing vibrio presence without any apparent impact over the natural microbiota at the family level in 28 libraries tested.

SIGNIFICANCE AND IMPACT OF THE STUDY

vB_Vc_SrVC9 is a novel phage and ecofriendly alternative for therapeutic applications and biotechnological purposes because is stable at different environmental conditions, has the potential to eliminate several strains, and has a short latent period with a good burst size. Therefore, the use of phages, which are natural killers of bacteria, represents a promising strategy to reduce the mortality of farmed organisms caused by pathogenic bacteria.

Patient experiences of fertility clinic closure during the COVID-19 pandemic: appraisals, coping and emotions

STUDY QUESTION

What are appraisals, coping strategies and emotional reactions of patients to coronavirus disease 2019 (COVID-19) fertility clinic closures?

SUMMARY ANSWER

Clinic closure was appraised as stressful due to uncertainty and threat to the attainability of the parenthood goal but patients were able to cope using strategies that fit the uncertainty of the situation.

WHAT IS KNOWN ALREADY

Psychological research on COVID-19 suggests that people are more anxious than historical norms and moderately to extremely upset about fertility treatment cancellation owing to COVID-19.

STUDY DESIGN, SIZE, DURATION

The study was of cross-sectional design, comprising a mixed-methods, English language, anonymous, online survey posted from April 09 to April 21 to social media. Eligibility criteria were being affected by COVID-19 fertility clinic closure, 18 years of age or older and able to complete the survey in English. In total, 946 people clicked on the survey link, 76 did not consent, 420 started but did not complete survey, and 450 completed (48% completion, 446 women, four men).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Overall 74.7% (n = 336) of respondents were residents in the UK with an average age of 33.6 years (SD = 4.4) and average years trying to conceive, 3.5 years (SD = 2.22). The survey comprised quantitative questions about the intensity of cognitive appraisals and emotions about clinic closure, and ability to cope with clinic closure. Open-text questions covered their understanding of COVID-19 and its effect on reproductive health and fertility plans, concerns and perceived benefits of clinic closure, and knowledge about closure. Sociodemographic information was collected. Descriptive and inferential statistics were used on quantitative data. Thematic qualitative analysis (inductive coding) was performed on the textual data from each question. Deductive coding grouped themes from each question into meta-themes related to cognitive stress and coping theory.

MAIN RESULTS AND THE ROLE OF CHANCE

Most patients (81.6%, n = 367) had tests or treatments postponed, with these being self (41.3%, n = 186) or publicly (46.4%, n = 209) funded. Patients appraised fertility clinic closure as having potential for a more negative than positive impact on their lives, and to be very or extremely uncontrollable and stressful (p ≤ .001). Most reported a slight to moderate ability to cope with closure. Data saturation was achieved with all open-text questions, with 33 broad themes identified and four meta-themes linked to components of the cognitive stress and coping theory. First, participants understood clinic closure was precautionary due to unknown effects of COVID-19 but some felt clinic closure was unfair relative to advice about getting pregnant given to the public. Second, closure was appraised as a threat to attainability of the parenthood goal largely due to uncertainty of the situation (e.g., re-opening, effect of delay) and intensification of pre-existing hardships of fertility problems (e.g., long time waiting for treatment, history of failed treatment). Third, closure taxed personal coping resources but most were able to cope using thought-management (e.g., distraction, focusing on positives), getting mentally and physically fit for next treatments, strengthening their social network, and keeping up-to-date. Finally, participants reported more negative than positive emotions (p ≤  .001) and almost all participants reported stress, worry and frustration at the situation, while some expressed anger and resentment at the unfairness of the situation. Overall, 11.9% were not at all able to cope, with reports of intense feelings of hopelessness and deteriorating wellbeing and mental health.

LIMITATIONS, REASONS FOR CAUTION

The survey captures patient reactions at a specific point in time, during lockdown and before clinics announced re-opening. Participants were self-selected (e.g., UK residents, women, 48% starting but not completing the survey), which may affect generalisability.

WIDER IMPLICATIONS OF THE FINDINGS

Fertility stakeholders (e.g., clinics, patient support groups, regulators, professional societies) need to work together to address the great uncertainty from COVID-19. This goal can be met proactively by setting up transparent processes for COVID-19 eventualities and signposting to information and coping resources. Future psychological research priorities should be on identifying patients at risk of distress with standardised measures and developing digital technologies appropriate for the realities of fertility care under COVID-19.

A fast technique to measure the dewpoint pressure of a retrograde condensate gas using a microfluidic volume

A new method to determine the dewpoint pressure of a retrograde condensate from a fast, non-equilibrium measurement performed in a microfluidic optical cell is presented. The inflection point of the optical transmission recorded during depressurization agrees well with the dewpoint pressure of the sample, determined by conventional laboratory techniques. With this new technique, a measurement can be performed in less than 5 min and requires far less than a milliliter of the sample. Benchmarking of this technique is presented using four retrograde condensate samples, which were created in the laboratory using multi-component compositions that are based on oilfield samples. Each sample was characterized at three different temperatures, and their maximum relative liquid volumes (maximum liquid volume/total system volume at the dewpoint pressure) ranged from 1.3% to 13.5% for these temperatures. The dewpoint pressure measured by this technique differs by no more than 100 psi from that measured in a conventional laboratory for samples of a richness of 4% or higher, while leaner samples display a difference of ∼200 psi.

An experimental evaluation of the benefits and costs of providing fertility information to adolescents and emerging adults

STUDY QUESTION

Does the provision of fertility (compared to control) information affect fertility-related knowledge, perceived threat of infertility, anxiety, physical stress and fertility plans in adolescents and emerging adults?

SUMMARY ANSWER

The provision of fertility information was associated with increased fertility knowledge (emerging adults) and greater infertility threat (adolescents and emerging adults).

WHAT IS KNOWN ALREADY

According to fertility education research, adolescents and emerging adults know less than they should know about fertility topics. Fertility knowledge can be improved through the provision of information in older adults.

STUDY DESIGN, SIZE, DURATION

Experimental design. Secondary and university students completed pre-information questionnaires, were randomly assigned via computer to an experimental group, read either fertility (FertiEduc group) or healthy pregnancy information (Control group), and completed post-information questionnaires. Data were collected in group sessions via an online portal.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Eligible participants were aged 16–18 (adolescents) or 21–24 years (emerging adults), childless, not currently pregnant (for men, partner not pregnant) or trying to conceive, presumed fertile and intending to have a child in the future. Of the 255 invited, 208 (n = 93 adolescents, n = 115 emerging adults) participated. The FertiEduc group received ‘A Guide to Fertility’, four online pages of information about fertility topics (e.g. ‘When are men and women most fertile?’) and the Control group received four online pages from the National Health Service (NHS) pregnancy booklet ‘Baby Bump and Beyond’. Participants completed a questionnaire (fertility knowledge, perceived threat of infertility, anxiety, physical stress and fertility plans, moderators) prior to and after the provision of information. Mixed factorial analysis of variance was used to examine the effects of information provision and hierarchical multiple regression to assess potential moderators of knowledge.

MAIN RESULTS AND THE ROLE OF CHANCE

The FertiEduc and Control groups were equivalent on age, gender, disability, relationship status and orientation at baseline. Results showed that fertility information significantly increased fertility knowledge for emerging adults only (P < 0.001) and threat of infertility for emerging adults and adolescents (P = 0.05). The moderators were not significant. Participation in the study was associated with an increase in feelings of anxiety but a decrease in physical stress reactions. Adolescents had more optimal fertility plans compared to emerging adults due to being younger.

LIMITATIONS, REASONS FOR CAUTION

This was an experimental study on a self-selected sample of men and women from selected educational institutions and only short term effects of information were studied.

WIDER IMPLICATIONS OF THE FINDINGS

Provision of fertility information can have benefits (increased fertility knowledge) but also costs (increase potential threat of infertility). Adolescents find fertility information positive but do not learn from it. Fertility education should be tailored according to age groups and created to minimise negative effects. Longitudinal examination of the effects of fertility information in multi-centre studies is warranted and should include measures of perceived threat of infertility.

Management of foot/ankle osteoarthritis by Australian general practitioners: an analysis of national patient-encounter records

OBJECTIVE

To document the management of foot/ankle osteoarthritis/arthritis (OA) by general practitioners (GP) in Australia.

DESIGN

We analysed data from the Bettering the Evaluation and Care of Health Program April 2010-March 2016 inclusive. Patient and GP encounter characteristics were extracted. Data were classified by the International Classification of Primary Care, Version 2, and summarised using descriptive statistics and 95% confidence intervals (95% CIs) around point estimates.

RESULTS

The dataset included 583,900 patient-encounter records among which foot/ankle OA was managed 621 times, at a rate of 1.1 per 1000 encounters, with an annual estimated 152,000 GP encounters nationally. The management rate was most frequent among patients aged 65-74 years (2.25 per 1000 encounters). Comorbidities were managed at a rate of 105.8 per 100 encounters, the most common being hypertension, and few being other musculoskeletal problems. Foot/ankle OA was mostly managed using medication (64.6 per 100 problems), with prescription rates far exceeding non-pharmacological strategies such as counselling, advice or education (17.7 per 100), or allied health referral (10.1 per 100). When considering specific health/medical professionals, patients were referred to orthopaedic surgeons 8.4 times per 100 foot/ankle problems, podiatrists 6.3 times per 100 foot/ankle problems, and physiotherapists 2.6 times per 100 foot/ankle problems.

CONCLUSIONS

Pharmacological management rates of foot/ankle OA were high and substantially exceeded non-pharmacological management such as lifestyle advice and allied health referral. Longitudinal studies are needed to determine the effectiveness of this care compared to self-management and conservative non-drug treatment in people with foot/ankle OA.

The Four-card Problem and the Generality of Formal Reasoning

Three experiments were designed to investigate the failure of intelligent adults to solve an apparently simple problem of formal reasoning devised by Wason. Both the mode of presentation and the type of material reduced the difficulty of the problem, while retaining its essential form. However, success on the original problem remained at a low level, even when subjects had attempted an easier version and had been given an explanation.

These results enable one to reject a “strong” formulation of Piaget's theory of formal reasoning. A “weaker” formulation is suggested as a basis for further research.

A descriptive single-centre experience of the management and outcome of maternal alloantibodies in pregnancy

BACKGROUND

Haemolytic disease of the fetus and newborn (HDFN) occurs when maternal IgG alloantibodies to fetal red blood cell antigens cross the placenta, causing haemolysis in the fetus and/or neonate. After delivery, the main concern is hyperbilirubinaemia, which can cause neurological damage.

OBJECTIVES

To summarise our current management and outcome data to inform health-care professionals counselling women whose pregnancies are at risk of HDFN and to compare these data with relevant studies.

METHODS

This is a retrospective descriptive study of all high-risk pregnancies at risk of HDFN at Guy's and St. Thomas' NHS Foundation Trust (GSTFT) Maternity Unit over a 7-year period. We defined high-risk pregnancies as those in whom anti-D, anti-c, anti-K or high (>32 or doubling strength) titres of all other antibodies were identified.

RESULTS

A total of 130 pregnancies in 112 women were followed up. A single alloantibody was found in 93 pregnancies (71.5%) and multiple alloantibodies in 37 pregnancies (28.5%). Anti-D was most commonly encountered (n = 48, 36.9%), followed by anti-c (n = 31, 23.8%) and anti-E (n = 15, 11.5%). In 65 of 130 pregnancies (50%), antibody concentrations triggered scans to screen for fetal anaemia. Of 130 pregnancies, 6 (4.6%) required intrauterine transfusions, and 31 of 130 (26%) neonates required post-natal intervention. Overall, morbidity was 0.1% and mortality 0.002%.

CONCLUSIONS

This study demonstrates that morbidity and mortality caused by HDFN is minimal. These results are reassuring for women at risk of HDFN as even severely affected cases are successfully managed in most instances. Further studies are needed to identify predictors of disease severity.
