ObjectivesRisk scores are recommended in guidelines to facilitate the management of patients who present with acute coronary syndromes (ACS). Internationally, such scores are not systematically used because they are not easy to apply and some risk indicators are not available at first presentation. We aimed to derive and externally validate a more accurate version of the Global Registry of Acute Coronary Events (GRACE) risk score for predicting the risk of death or death/myocardial infarction (MI) both acutely and over the longer term. The risk score was designed to be suitable for acute and emergency clinical settings and usable in electronic devices.Design and settingThe GRACE risk score (2.0) was derived in 32 037 patients from the GRACE registry (14 countries, 94 hospitals) and validated externally in the French registry of Acute ST-elevation and non-ST-elevation MI (FAST-MI) 2005.ParticipantsPatients presenting with ST-elevation and non-ST elevation ACS and with long-term outcomes.Outcome measuresThe GRACE Score (2.0) predicts the risk of short-term and long-term mortality, and death/MI, overall and in hospital survivors.ResultsFor key independent risk predictors of death (1 year), non-linear associations (vs linear) were found for age (p<0.0005), systolic blood pressure (p<0.0001), pulse (p<0.0001) and creatinine (p<0.0001). By employing non-linear algorithms, there was improved model discrimination, validated externally. Using the FAST-MI 2005 cohort, the c indices for death exceeded 0.82 for the overall population at 1 year and also at 3 years. Discrimination for death or MI was slightly lower than for death alone (c=0.78). Similar results were obtained for hospital survivors, and with substitutions for creatinine and Killip class, the model performed nearly as well.ConclusionsThe updated GRACE risk score has better discrimination and is easier to use than the previous score based on linear associations. GRACE Risk (2.0) performed equally well acutely and over the longer term and can be used in a variety of clinical settings to aid management decisions.

ObjectiveTo investigate the infant feeding experiences of women and their significant others from pregnancy until 6 months after birth to establish what would make a difference.DesignQualitative serial interview study.SettingTwo health boards in Scotland.Participants72 of 541 invited pregnant women volunteered. 220 interviews approximately every 4 weeks with 36 women, 26 partners, eight maternal mothers, one sister and two health professionals took place.ResultsThe overarching theme was a clash between overt or covert infant feeding idealism and the reality experienced. This is manifest as pivotal points where families perceive that the only solution that will restore family well-being is to stop breast feeding or introduce solids. Immediate family well-being is the overriding goal rather than theoretical longer term health benefits. Feeding education is perceived as unrealistic, overly technical and rules based which can undermine women's confidence. Unanimously families would prefer the balance to shift away from antenatal theory towards more help immediately after birth and at 3–4 months when solids are being considered. Family-orientated interactive discussions are valued above breastfeeding-centred checklist style encounters.ConclusionsAdopting idealistic global policy goals like exclusive breast feeding until 6 months as individual goals for women is unhelpful. More achievable incremental goals are recommended. Using a proactive family-centred narrative approach to feeding care might enable pivotal points to be anticipated and resolved. More attention to the diverse values, meanings and emotions around infant feeding within families could help to reconcile health ideals with reality.

IntroductionDesert dust concentrations raise concerns about adverse effects on human health. During the last decade, special attention has been given to mineral dust particles from desert dust and sand storms. However, evidence from previous reviews reported inconclusive results on their health effects and the biological mechanism remains unclear. We aim to systematically synthesise evidence on the health effects of desert dust and sand storms accounting for the relevant desert dust patterns from source areas and emissions, transport and composition.Methods an analysisWe will conduct a systematic review that investigated the health effects of desert dust and sand storms in any population. The search will be performed for any eligible studies from previous reviews and selected electronic databases until 2018. Study selection and reporting will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data from individual studies will be extracted using a standardised data extraction form. Quality of the studies will be assessed using a risk of bias tool for environmental exposures developed by experts convened by the WHO. A meta-analysis will be performed by calculating the appropriate effect measures of association for binary and continuous outcomes from individual studies. Subgroup analyses will be performed by geographical areas to account for desert dust patterns.Ethics and disseminationNo primary data will be collected. For this reason, no formal ethical approval is required. This systematic review will help to fill the research gaps in the knowledge of desert dust on human health. The results will be disseminated through a WHO peer-reviewed publication and a conference presentation.PROSPERO registration numberCRD42018091809

IntroductionThe skin is an important barrier against environmental allergens, but infants have relatively impaired skin barrier function. There is evidence that impaired skin barrier function increases the risk of allergic sensitisation, atopic dermatitis (AD) and food allergy. We hypothesise that regular prophylactic use of emollients, particularly those that are designed to improve skin barrier structure and function, will help prevent these conditions. With the aim of determining if application of a ceramide-dominant emollient two times per day reduces the risk of AD and food allergy, we have commenced a multicentre phase III, outcome assessor blinded, randomised controlled trial of this emollient applied from birth to 6 months.Methods and analysisInfants (n=760) with a family history of allergic disease will be recruited from maternity hospitals in Melbourne. The primary outcomes are as follows: the presence of AD, assessed using the UK Working Party criteria, and food allergy using food challenge, in the first 12 months of life as assessed by a blinded study outcome assessor. Secondary outcomes are as follows: food sensitisation (skin prick test), skin barrier function, AD severity, the presence of new onset AD after treatment cessation (between 6 and 12 months) and the presence of parent reported AD/eczema. Recruitment commenced in March 2018.Ethics and disseminationThe PEBBLES Study is approved by the Human Research Ethics Committees of the Royal Children’s Hospital (RCH) (#37090A) and the Mercy Hospital for Women (2018–008). Parents or guardians will provide written informed consent. Outcomes will be disseminated through peer-reviewed publications and presented at scientific conferences.Trial registration numbersACTRN12617001380381 andNCT03667651.

ObjectiveTo describe physician perspectives on the causes of and solutions to obesity care and identify differences in these perspectives by number of years since completion of medical school.DesignNational cross-sectional online survey from 9 February to 1 March 2011.SettingUSA.Participants500 primary care physicians.Main MeasuresWe evaluated physician perspectives on: (1) causes of obesity, (2) competence in treating obese patients, (3) perspectives on the health professional most qualified to help obese patients lose or maintain weight and (4) solutions for improving obesity care.ResultsPrimary care physicians overwhelmingly supported additional training (such as nutrition counselling) and practice-based changes (such as having scales report body mass index) to help them improve their obesity care. They also identified nutritionists/dietitians as the most qualified providers to care for obese patients. Physicians with fewer than 20 years since completion of medical school were more likely to identify lack of information about good eating habits and lack of access to healthy food as important causes of obesity. They also reported feeling relatively more successful helping obese patients lose weight. The response rate for the survey was 25.6%.ConclusionsOur results indicate a perceived need for improved medical education related to obesity care.

ObjectivesTo examine the effect that health professional (HP) advice to lose weight has on overweight and obese adults’ motivation to lose weight and attempts to lose weight.DesignCross-sectional survey.SettingGreat Britain.Participants810 overweight or obese (body mass index ≥25 kg/m2) adults.Main outcome measuresParticipants were asked if they had ever received HP advice to lose weight and reported their desire to weigh less (ideal weight ≤95% of current weight) and whether they were attempting to lose weight.ResultsOnly 17% of overweight and 42% of obese respondents recalled ever having received HP advice to lose weight. HP advice was associated with wanting to weigh less (89% vs 61% among those not receiving advice) and attempting to lose weight (68% vs 37%). In multivariable analyses, HP advice to lose weight was associated with increased odds of wanting to weigh less (OR=3.71, 95% CI 2.10 to 6.55) and attempting to lose weight (OR=3.53, 95% CI 2.44 to 5.10) independent of demographic characteristics and weight status.ConclusionsHP advice to lose weight appears to increase motivation to lose weight and weight loss behaviour, but only a minority of overweight or obese adults receive such advice. Better training for HPs in delivering brief weight counselling could offer an opportunity to improve obese patients’ motivation to lose weight.

ObjectivesTimely recognition and treatment of sepsis is essential to reduce mortality and morbidity. Acutely ill patients often consult a general practitioner (GP) as the first healthcare provider. During out-of-hours, GP cooperatives deliver this care in the Netherlands. The aim of this study is to explore the role of these GP cooperatives in the care for patients with sepsis.DesignRetrospective study of patient records from both the hospital and the GP cooperative.SettingAn intensive care unit (ICU) of a general hospital in the Netherlands, and the colocated GP cooperative serving 260 000 inhabitants.ParticipantsWe used data from 263 patients who were admitted to the ICU due to community-acquired sepsis between January 2011 and December 2015.Main outcome measuresContact with the GP cooperative within 72 hours prior to hospital admission, type of contact, delay from the contact until hospital arrival, GP diagnosis, initial vital signs and laboratory values, and hospital mortality.ResultsOf 263 patients admitted to the ICU, 127 (48.3%) had prior GP cooperative contacts. These contacts concerned home visits (59.1%), clinic consultations (18.1%), direct ambulance deployment (12.6%) or telephone advice (10.2%). Patients assessed by a GP were referred in 64% after the first contact. The median delay to hospital arrival was 1.7 hours. The GP had not suspected an infection in 43% of the patients. In this group, the in-hospital mortality rate was significantly higher compared with patients with suspected infections (41.9% vs 17.6%). Mortality difference remained significant after correction for confounders.ConclusionGP cooperatives play an important role in prehospital management of sepsis and recognition of sepsis in this setting proved difficult. Efforts to improve management of sepsis in out-of-hours primary care should not be limited to patients with a suspected infection, but also include severely ill patients without clear signs of infection.

ObjectiveEarly identification of sepsis could enable prompt delivery of key interventions such as fluid resuscitation and antibiotic administration which, in turn, may lead to improved patient outcomes. Limited data indicate that recognition of sepsis by paramedics is often poor. We systematically reviewed the literature on prehospital sepsis screening tools to determine whether they improved sepsis recognition.DesignSystematic review. The electronic databases MEDLINE, EMBASE, CINAHL, the Cochrane Library and PubMed were systematically searched up to June 2015. In addition, subject experts were contacted.SettingPrehospital/emergency medical services (EMS).Study selectionAll studies addressing identification of sepsis (including severe sepsis and septic shock) among adult patients managed by EMS.Outcome measuresRecognition of sepsis by EMS clinicians.ResultsOwing to considerable variation in the methodological approach adopted and outcome measures reported, a narrative approach to data synthesis was adopted. Three studies addressed development of prehospital sepsis screening tools. Six studies addressed paramedic diagnosis of sepsis with or without use of a prehospital sepsis screening tool.ConclusionsRecognition of sepsis by ambulance clinicians is poor. The use of screening tools, based on the Surviving Sepsis Campaign diagnostic criteria, improves prehospital sepsis recognition. Screening tools derived from EMS data have been developed, but they have not yet been validated in clinical practice. There is a need to undertake validation studies to determine whether prehospital sepsis screening tools confer any clinical benefit.

ObjectivesTo describe (1) cardiac rehabilitation (CR) referral across cardiac units in a tertiary centre with eReferral; (2) characteristics associated with CR referral and enrolment and (3) the effects of peer navigation (PN) on referral and enrolment. This pilot was a 2 parallel-arm, randomised, single-blind trial with allocation concealment.Setting3 cardiac units (ie, interventional, general cardiology, and cardiac surgery) in 1 of 2 hospitals of a tertiary centre.ParticipantsCR-eligible adult cardiac inpatients were randomised to PN or usual care. 94 (54.7%) patients consented, of which 46 (48.9%) were randomised to PN. Outcomes were ascertained in 76 (80.9%) participants.InterventionThe PN (1) visited participant at the bedside, (2) mailed a card to participant's home reminding about CR and (3) called participant 2 weeks postdischarge to discuss CR barriers.Outcome measuresThe primary outcome of enrolment was defined as participant attendance at a scheduled CR intake appointment (yes/no). The secondary outcome was referral. Blinded outcome assessment was conducted 12 weeks postdischarge, via CR chart extraction.ResultsThose who received care on the cardiac surgery unit (77.9%) were more likely to be referred than those treated on the general cardiology (61.1%) or interventional unit (33.3%; p=0.04). Patients who had cardiac surgery, hypertension and hyperlipidaemia were significantly more likely, and those with congenital heart disease, cancer and a previous cardiac diagnosis were less likely to be referred. Participants referred to a site closer to home (76.2% of those referred) were more likely to enrol than those not (23.7%, p<0.05). PN had no effect on referral (77.6%, p=0.45) or enrolment (46.0%, p=0.24).ConclusionsThere is wide variability in CR referral, even within academic centres, and despite eReferral. Referral was quite high, and thus, PN did not improve CR utilisation. Results support triaging patients to the CR programme closest to their home.Trial registration numberNCT02204449; Results.

ObjectiveSummarise longitudinal observational studies to determine whether diabetes (types 1 and 2) is a risk factor for frozen shoulder.DesignSystematic review and meta-analysis.Data sourcesMEDLINE, Embase, AMED, PsycINFO, Web of Science Core Collection, CINAHL, Epistemonikos, Trip, PEDro, OpenGrey and The Grey Literature Report were searched on January 2019 and updated in June 2021. Reference screening and emailing professional contacts were also used.Eligibility criteriaLongitudinal observational studies that estimated the association between diabetes and developing frozen shoulder.Data extraction and synthesisData extraction was completed by one reviewer and independently checked by another using a predefined extraction sheet. Risk of bias was judged using the Quality In Prognosis Studies tool. For studies providing sufficient data, random-effects meta-analysis was used to derive summary estimates of the association between diabetes and the onset of frozen shoulder.ResultsA meta-analysis of six case–control studies including 5388 people estimated the odds of developing frozen shoulder for people with diabetes to be 3.69 (95% CI 2.99 to 4.56) times the odds for people without diabetes. Two cohort studies were identified, both suggesting diabetes was associated with frozen shoulder, with HRs of 1.32 (95% CI 1.22 to 1.42) and 1.67 (95% CI 1.46 to 1.91). Risk of bias was judged as high in seven studies and moderate in one study.ConclusionPeople with diabetes are more likely to develop frozen shoulder. Risk of unmeasured confounding was the main limitation of this systematic review. High-quality studies are needed to confirm the strength of, and understand reasons for, the association.PROSPERO registration numberCRD42019122963.
