PurposeTo report the ocular characteristics and the presence of viral RNA of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in conjunctival swab specimens in a patient with confirmed 2019 novel coronavirus disease (COVID-19).Participant and methodsA 30-year-old man with confirmed COVID-19 and bilateral acute conjunctivitis which occurred 13 days after illness onset. Based on detailed ophthalmic examination, reverse transcription PCR (RT-PCR) was performed to detect SARS-CoV-2 virus in conjunctival swabs. The ocular characteristics, presence of viral RNA and viral dynamics of SARS-CoV-2 in the conjunctival specimens were evaluated.ResultsSlit lamp examination showed bilateral acute follicular conjunctivitis. RT-PCR assay demonstrated the presence of viral RNA in conjunctival specimen 13 days after onset (cycle threshold value: 31). The conjunctival swab specimens remained positive for SARS-CoV-2 on 14 and 17 days after onset. On day 19, RT-PCR result was negative for SARS-CoV-2.ConclusionSARS-CoV-2 is capable of causing ocular complications such as viral conjunctivitis in the middle phase of illness. Precautionary measures are recommended when examining infected patients throughout the clinical course of the infection. However, conjunctival sampling might not be useful for early diagnosis because the virus may not appear initially in the conjunctiva.

IntroductionAcute kidney injury (AKI) is a frequent complication after cardiac surgery with adverse short-term and long-term outcomes. Although prevention of AKI (PrevAKI) is strongly recommended, the optimal strategy is uncertain. The Kidney Disease: Improving Global Outcomes (KDIGO) guideline recommended a bundle of supportive measures in high-risk patients. In a single-centre trial, we recently demonstrated that the strict implementation of the KDIGO bundle significantly reduced the occurrence of AKI after cardiac surgery. In this feasibility study, we aim to evaluate whether the study protocol can be implemented in a multicentre setting in preparation for a large multicentre trial.Methods and analysisWe plan to conduct a prospective, observational survey followed by a randomised controlled, multicentre, multinational clinical trial including 280 patients undergoing cardiac surgery with cardiopulmonary bypass. The purpose of the observational survey is to explore the adherence to the KDIGO recommendations in routine clinical practice. The second phase is a randomised controlled trial. The objective is to investigate whether the trial protocol is implementable in a large multicentre, multinational setting. The primary endpoint of the interventional part is the compliance rate with the protocol. Secondary endpoints include the occurrence of any AKI and moderate/severe AKI as defined by the KDIGO criteria within 72 hours after surgery, renal recovery at day 90, use of renal replacement therapy (RRT) and mortality at days 30, 60 and 90, the combined endpoint major adverse kidney events consisting of persistent renal dysfunction, RRT and mortality at day 90 and safety outcomes.Ethics and disseminationThe PrevAKI multicentre study has been approved by the leading Research Ethics Committee of the University of Münster and the respective Research Ethics Committee at each participating site. The results will be used to design a large, definitive trial.Trial registration numberNCT03244514.
Core outcome set in paediatric sepsis in low- and middle-income countries: a study protocol
Authors: Wooldridge Gavin , Murthy Srinivas , Kissoon Niranjan 
Published: April 2020

IntroductionSepsis is the leading cause of death in children worldwide and has recently been declared a major global health issue. New interventions and a concerted effort to enhance our understanding of sepsis are required to address the huge burden of disease, especially in low- and middle-income countries (LMIC) where it is highest. An opportunity therefore exists to ensure that ongoing research in this area is relevant to all stakeholders and is of consistently high quality. One method to address these issues is through the development of a core outcome set (COS).Methods and analysisThis study protocol outlines the phases in the development of a core outcome set for paediatric sepsis in LMIC. The first step involves performing a systematic review of all outcomes reported in the research of paediatric sepsis in low middle-income countries. A three-stage international Delphi process will then invite a broad range of participants to score each generated outcome for inclusion into the COS. This will include an initial two-step online survey and finally, a face-to-face consensus meeting where each outcome will be reviewed, voted on and ratified for inclusion into the COS.Ethics and disseminationNo core outcome sets exist for clinical trials in paediatric sepsis. This COS will serve to not only highlight the heavy burden of paediatric sepsis in this setting and aid collaboration and participation between all stakeholders, but to promote ongoing essential high quality and relevant research into the topic. A COS in paediatric sepsis in LMIC will advocate for a common language and facilitate interpretation of findings from a variety of settings. A waiver for ethics approval has been granted by University of British Columbia Children’s and Women’s Research Ethics Board.

Published: April 2020

IntroductionWhen adolescents experience complex psychiatric and social problems, numerous healthcare services usually become involved. In these cases, fragmentation of care services is a risk that often results in both ineffective care and in patients disengaging from care services. To address these issues, Youth Flexible Assertive Community Treatment (Youth Flexible ACT) was developed in the Netherlands. This client-centred service delivery model aims to tackle the fragmented care system by providing psychiatric treatment and support in a flexible and integrated manner. While Youth Flexible ACT is gaining in popularity, the effectiveness of the care model remains largely unexamined.Methods and analysisHere, we present an observational prospective cohort (2017–2021) in which a broad range of treatment outcomes will be monitored. The primary aim of the study is to examine change in treatment outcomes over the course of the Flexible ACT care. The secondary aim is to examine the association between (elements of) Youth Flexible ACT model fidelity and treatment outcomes. An estimated total number of 200 adolescents who receive care from one of the 16 participating Youth Flexible ACT teams will be included in the study. Participants will be asked to complete assessments at four time points in 6-month intervals, resulting in a study duration of 18 months. Latent growth curve analysis will be conducted to examine change in psychosocial functioning over time and its relation to model fidelity.Ethics and disseminationThis study received ethical approval from Trimbos Ethics Committee (201607_75-FACT2). This approval applies for all participating institutions. The results of the study will be reported in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology statement. Results will be disseminated via peer-reviewed academic journals and presentations at conferences. In addition, results will be made available for participating sites, funders and researchers.

ObjectiveTo investigate: (1) patient and family experiences with healthcare and the intensive care unit (ICU); (2) experiences during their critical illness; (3) communication and decision making during critical illness; (4) feelings about the ICU experience; (5) impact of the critical illness on their lives; and (6) concerns about their future after the ICU.DesignFour semistructured focus group interviews with former ICU patients and family members.SettingsMulticultural community group and local hospitals containing medical/surgical ICUs.ParticipantsPatients and family who experienced a critical illness within the previous 10 years.InterventionsNone.Measurements and main resultsFour separate focus groups each lasting a maximum of 150 min and consisting of a total of 21 participants were held. Focus groups were conducted using a semistructured script including six topics relating to the experience of critical illness that facilitated deduction and the sorting of data by thematic analysis into five predominant themes. The five main themes that emerged from the data were: (1) personalised stories of the critical illness; (2) communication and shared decision making, (3) adjustment to life after critical illness, (4) trust towards clinical team and relevance of cultural beliefs and (5) end-of-life decision making. Across themes, we observed a misalignment between the medical system and patient and family values and priorities.ConclusionsThe experience of critical illness of a diverse group of patients and families can remain vivid for years after ICU discharge. The identified themes reflect the strength of memory of such pivotal experiences and the importance of a narrative around those experiences. Clinicians need to be aware of the lasting effects of critical illness has on patients and families.

ObjectivesIn this study, we aimed to estimate the prevalence of metabolic syndrome (MetS) among Chinese adults, describe the disease components and compare utility of the existing international criteria and Chinese diagnostic criteria.Design, setting and participantsA retrospective database analysis was conducted for one hospital in Zhejiang province, China. We analysed data (collected in 2017) from a total of 64 902 participants (37 500 males and 27 402 females), aged between 18 and 97 years, and who met the eligibility criteria.Main outcome measuresWe employed three criteria for MetS proposed by the International Diabetes Federation (IDF) in 2005, the 2009 Joint Scientific Statement (harmonising criteria) and the China Diabetes Society (CDS) in 2013 to detect prevalence of MetS. Specifically, we analysed waist circumference, blood pressure, fasting plasma glucose, plasma triglycerides and plasma high-density lipoprotein cholesterol.ResultsWe found an estimated age-adjusted MetS prevalence of 20.4% using IDF 2005, 30.0% based on harmonising criteria 2009 and 16.3% under the CDS 2013. This prevalence was higher in males, older adults and increased body mass index. Analysis of agreements among the criteria were 87.2% (IDF and CDS), 87.1% (IDF and harmonising criteria) and 81.6% (CDS and harmonising criteria), while their kappa coefficients were 0.641, 0.708 and 0.572 for IDF versus CDS, IDF versus harmonising criteria and CDS versus harmonising criteria, respectively. The most prevalent MetS component was abdominal obesity (50.1%), followed by dyslipidaemia (49.5%) and hypertension (46.8%) using harmonising criteria.ConclusionThese findings revealed moderate agreement among the three criteria with utility in Chinese clinical settings. The harmonising criteria 2009 performed better in early identification of MetS in the Chinese population.

ObjectiveLeadership is associated with organisational performance in healthcare, including quality, safety and clinical outcomes for patients. Leadership development programmes have proliferated in recent years. Nevertheless, very few have examined participant experiences in depth in order to understand which programmatic aspects they regard as most valuable relative to leadership in increasingly complex systems, or whether and how learnings may sustain over time. Accordingly, we explored experiences of participants in an interdisciplinary leadership development programme using qualitative methods over an extended look-back period.SettingHealth and social care sectors in the UK.ParticipantsKey informants from three cohorts of individuals working in leadership roles in health and social care in the UK: 2013/2014, 2015/2016 and 2017/2018. We contacted 32 participants, and 26 completed interviews (81% response rate).Primary and secondary outcomesWe explored (1) whether and how specific skills and competencies developed during the programme were applied and/or sustained over time, and (2) whether and how the impact of the programme changed as alumni progressed through their career.ResultsThree major recurrent themes emerged from participants’ experiences: (1) specific features of the programme meaningfully impact professional development at multiple levels; (2) the coupling of a professional network and practical tools allowed participants to address system-wide problems in new ways and (3) participants describe a level of learning that sustained and amplified over time with increased complexity in their work.ConclusionThis work highlights specific design characteristics of leadership development programmes that may help promote relevance and impact. Programme learnings can be translated into practice in substantive ways, with potential for the benefits of successful leadership development efforts to amplify, not fade, over time.

IntroductionIntravenous thrombolysis (IVT) with recombinant tissue plasminogen activator (rt-PA) is the only approved pharmacological reperfusion therapy for acute ischaemic stroke. Despite population benefit, IVT is not equally effective in all patients, nor is it without significant risk. Uncertain treatment outcome prediction complicates patient treatment selection. This study will develop and validate predictive algorithms for IVT response, using clinical, radiological and blood-based biomarker measures. A secondary objective is to develop predictive algorithms for endovascular thrombectomy (EVT), which has been proven as an effective reperfusion therapy since study inception.Methods and analysisThe Targeting Optimal Thrombolysis Outcomes Study is a multicenter prospective cohort study of ischaemic stroke patients treated at participating Australian Stroke Centres with IVT and/or EVT. Patients undergo neuroimaging using multimodal CT or MRI at baseline with repeat neuroimaging 24 hours post-treatment. Baseline and follow-up blood samples are provided for research use. The primary outcome is good functional outcome at 90 days poststroke, defined as a modified Rankin Scale (mRS) Score of 0–2. Secondary outcomes are reperfusion, recanalisation, infarct core growth, change in stroke severity, poor functional outcome, excellent functional outcome and ordinal mRS at 90 days. Primary predictive models will be developed and validated in patients treated only with rt-PA. Models will be built using regression methods and include clinical variables, radiological measures from multimodal neuroimaging and blood-based biomarkers measured by mass spectrometry. Predictive accuracy will be quantified using c-statistics and R2. In secondary analyses, models will be developed in patients treated using EVT, with or without prior IVT, reflecting practice changes since original study design.Ethics and disseminationPatients, or relatives when patients could not consent, provide written informed consent to participate. This study received approval from the Hunter New England Local Health District Human Research Ethics Committee (reference 14/10/15/4.02). Findings will be disseminated via peer-reviewed publications and conference presentations.

Published: April 2020

ObjectivesTwo hundred thousand children worldwide are blind from cataract. Late presentation for surgery resulting in poor visual outcomes is a problem globally. We aimed to explore the reasons why children are not brought earlier for surgery in Nepal.Methods and analysisMixed-method study of carers of children with bilateral cataract attending a large non-government eye hospital were administered a proforma. A random sample took part in semistructured interviews and focus group discussions.ResultsCarers of 102 children completed proformas; 10 interviews and 2 focus group discussions were held. 80.4% were Indian, 35.3% of children were female, and their mean age was 58 months (range 4 months to 10 years). Median delay in time between the carer first noticing a problem to presentation was 182 days IQR (60.8–364.8). This was significantly longer for girls (median 304 IQR (91.2–1094.4)) than boys (median 121.6 IQR (30.4–364.8); p=0.02). Cost to access care was a problem for 42 (41.2%) carers. 13 (12.8%) participants were not aware of treatment and 12 (11.8%) were aware but did not seek treatment. The community influenced carer’s health-seeking behaviour. Cataract was sometimes described as ‘phula’, meaning something white seen on the eye.ConclusionFewer girls presented for surgery, and they also had a significantly longer delay to presentation than boys. Carers are influenced by factors at family, community and socio-organisational levels. Approaches to increase timely access, particularly by girls, are required, such as health education using the term phula, which is widely understood.
Use of menstruation and fertility app trackers: a scoping review of the evidence
Authors: Earle Sarah , Marston Hannah R , Hadley Robin , Banks Duncan 
Published: April 2020

IntroductionThere has been a phenomenal worldwide increase in the development and use of mobile health applications (mHealth apps) that monitor menstruation and fertility. Critics argue that many of the apps are inaccurate and lack evidence from either clinical trials or user experience. The aim of this scoping review is to provide an overview of the research literature on mHealth apps that track menstruation and fertility.MethodsThis project followed the PRISMA Extension for Scoping Reviews. The ACM, CINAHL, Google Scholar, PubMed and Scopus databases were searched for material published between 1 January 2010 and 30 April 2019. Data summary and synthesis were used to chart and analyse the data.ResultsIn total 654 records were reviewed. Subsequently, 135 duplicate records and 501 records that did not meet the inclusion criteria were removed. Eighteen records from 13 countries form the basis of this review. The papers reviewed cover a variety of disciplinary and methodological frameworks. Three main themes were identified: fertility and reproductive health tracking, pregnancy planning, and pregnancy prevention.ConclusionsMotivations for fertility app use are varied, overlap and change over time, although women want apps that are accurate and evidence-based regardless of whether they are tracking their fertility, planning a pregnancy or using the app as a form of contraception. There is a lack of critical debate and engagement in the development, evaluation, usage and regulation of fertility and menstruation apps. The paucity of evidence-based research and absence of fertility, health professionals and users in studies is raised.

ObjectiveNon-alcoholic fatty liver disease (NAFLD) affects approximately one in four adults of the general population, with an important minority of cases at high risk of developing cirrhosis. We evaluated the utility of a primary care NAFLD pathway incorporating a specialist nurse-led NAFLD clinic and a two-step testing approach for advanced liver fibrosis.Design/MethodWe performed a retrospective evaluation of prospectively collected demographic and clinical data on all patients diagnosed with NAFLD and intermediate NAFLD fibrosis score seen in our nurse-led NAFLD clinic between 1 May 2014 and 30 April 2017. Patients were assessed using a specific clerking pro forma and transient elastography (TE). Discharge to primary care with lifestyle advice was considered where TE<7.9 kPa.Results904 patients were identified, 114 (12.6%) of whom did not meet NAFLD criteria. Among the NAFLD population (n=790 (87.4%)), TE<7.9 kPa was present in 558 patients (70.6%), 519 of whom were discharged to primary care. Selected patients were followed up in secondary care despite TE<7.9 kPa or discharged with TE≥7.9 kPa. TE was unreliable in 22 patients (2.7%). Overall, 559 (70.8%) of patients with confirmed NAFLD were discharged from the nurse-led clinic. Introduction of the new pathway was associated with increased screening for hepatitis B and C viruses in primary care, and 17 new cases of alpha-1-antitrypsin deficiency were identified.ConclusionAn integrated primary/secondary care NAFLD pathway, including a specialist nurse-led clinic may be a useful way of managing increasing demand on secondary care hepatology services.
