ObjectiveWe aimed to estimate the distribution of health-related behaviours and dietary habits by sociodemographics among public workers in China.DesignCross-sectional study.SettingA representative sample was obtained from 10 government-run institutions in Hunan province of China.ParticipantsA total of 5029 public workers were included in this study.Primary and secondary outcome measuresPrevalence on their sociodemographic characteristics, health-related behaviours and dietary habits. Socioeconomic status (SES) scores were calculated by multiplying ordinal numerical values assigned to consecutive categories of education level and annual household income. Multivariate logistic regression analysis and categorical principal component analysis were used to estimate differences in health-related behaviours and dietary habits by sociodemographics.ResultsThe distribution of health-related behaviours and dietary habits was varied by sociodemographic groups. Middle-aged groups (41–60 years) were more likely to smoke (for men, 34.5%), use alcohol (for men, 22.5%), and have short sleep duration (for men, 36.3%; for women, 39.6%). Young participants (≤30 years) were more likely to have multiple unhealthy behaviours and dietary habits. Those in low-SES have a significant higher rate of smoking (ORadj=1.46, 95% CI: 1.15 to 1.85) and leisure-time physical inactivity (ORadj=1.18, 95% CI: 1.02 to 1.37), but a lower rate of late sleeping (ORadj=0.69, 95% CI: 0.57 to 0.83) than those in high-SES. Notably, older men (≥51 years) with low-SES preferred the ‘smoked and pickled foods and dessert’ and ‘fish and nut’ pattern. In high-SES groups, 41–50 year old people preferred the ‘traditional foods’ and ‘cereals and dairy product’ pattern. No difference in dietary patterns by sociodemographics was found among women (p<0.05).ConclusionsOur findings of the disparity distribution of health-related behaviours and dietary habits by specific gender, age and SES among Chinese public workers have important policy implications for developing targeted health interventions to facilitate health-related behaviours and dietary habits in this population.

Published: August 2021

IntroductionAboriginal and Torres Strait Islander women experience a higher burden of cervical cancer than non-Indigenous women in Australia. Cervical cancer is preventable partly through human papillomavirus (HPV) vaccination; in Australia, this is delivered through the national school-based immunisation programme. While HPV vaccination uptake is high among Australian adolescents, there remain gaps in uptake and completion among Aboriginal and Torres Strait Islander adolescents. This study aims to gain a comprehensive understanding of the barriers and facilitators to HPV vaccination uptake and completion among Aboriginal and Torres Strait Islander adolescents in Queensland, Australia.Methods and analysisThe study will be guided by an Indigenist research approach and an ecological model for health promotion. Yarning, a qualitative Indigenous research method, will be conducted in up to 10 schools. Participants will include Year 7 (12/13 years old) Aboriginal and Torres Strait Islander adolescents; parents/caregivers; and local key informants and immunisation programme partners involved in the delivery of school-based HPV immunisation programme. Participants will be recruited through school representatives and investigator networks using purposive and snowball sampling and samples of convenience. Field notes, HPV vaccination clinic observations and sequential diagramming of the HPV vaccination process will be conducted. Thematic analysis of data will be led by Aboriginal and Torres Strait Islander researchers. Synthesised sequential diagrams of the process of HPV vaccination and qualitative themes summarising key findings will be produced.Ethics and disseminationThe Aboriginal Health and Medical Research Council of New South Wales Ethics Committee (1646/20), the Australian National University Human Research Ethics Committee (HREC, 2020/478), the HREC of the Northern Territory Department of Health and Menzies School of Health Research (19-3484) and the Townsville Hospital and Health Service HREC (HREC/QTHS/73789) have approved the study. Dissemination will occur via conferences and peer-reviewed publications. Further dissemination will be determined in partnership with the Aboriginal and Torres Strait Islander Steering Committee, including Youth Representatives and Consultation Network.

PurposeThe COCCINELLE study is a nationwide retrospective French cohort set up to evaluate the risk of cancer in patients who undergone cardiac catheterisation (CC) procedures for diagnosis or treatment of congenital heart disease during childhood.ParticipantsChildren who undergone CC procedures from 1 January 2000 to 31 December 2013, before the age of 16 in one of the 15 paediatric cardiology departments which perform paediatric CC in mainland France were included. The follow-up started at the date of the first recorded CC procedure until the exit date, that is, the date of death, the date of first cancer diagnosis, the date of the 18th birthday or the 31 December 2015, whichever occurred first. The cohort was linked to the National Childhood Cancer Registry to identify patients diagnosed with cancer and with the French National Directory for the Identification of Natural Persons to retrieve the patients’ vital status.Findings to dateA total of 17 104 children were included in the cohort and followed for 110 335 person-years, with 22 227 CC procedures collected. Among the patients, 81.6% received only one procedure. Fifty-nine cancer cases were observed in the cohort. Standardised incidence ratios (SIRs) were increased for all-cancer (SIR=3.8, 95% CI: 2.9 to 4.9), leukaemia (SIR=3.3, 95% CI: 2.0 to 5.4), lymphoma (SIR=14.9, 95% CI: 9.9 to 22.5) and solid cancers excluding central nervous system (CNS) tumours (SIR=3.3, 95% CI: 2.0 to 5.5) compared with the general population.Future plansDose reconstruction is currently underway to estimate individual cumulative doses absorbed to relevant organs, including red bone marrow and brain for respectively haematologic disorders and CNS tumours risk estimation. A dose–response analysis will be conducted with consideration to confounding factors such as age at exposure, gender, predisposing factors to cancer and other sources of medical diagnostic low-dose ionising radiation.

ObjectivesWe investigate the prevalence of unmet need arising from wait times, distance/transportation and financial affordability using the European Health Interview Survey. We explore associations between individual characteristics and the probability of reporting unmet need.DesignCross-sectional survey conducted between February and December 2014.Setting and participants4004 members of the resident population in private households registered with the health insurance fund in Luxembourg aged 15 years and over.Outcome measuresSix binary variables that measured unmet need arising from wait time, distance/transportation and affordability of medical, dental and mental healthcare and prescribed medicines among those who reported a need for care.ResultsThe most common barrier to access arose from wait times (32%) and the least common from distance/transportation (4%). Dental care (12%) was most often reported as unaffordable, followed by prescribed medicines (6%), medical (5%) and mental health (5%) care. Respondents who reported bad/very bad health were associated with a higher risk of unmet need compared with those with good/very good health (wait: OR 2.41, 95% CI 1.53 to 3.80, distance/transportation: OR 7.12, 95% CI 2.91 to 17.44, afford medical care: OR 5.35, 95% CI 2.39 to 11.95, afford dental care: OR 3.26, 95% CI 1.86 to 5.71, afford prescribed medicines: OR 2.22, 95% CI 1.04 to 4.71, afford mental healthcare: OR 3.58, 95% CI 1.25 to 10.30). Income between the fourth and fifth quintiles was associated with a lower risk of unmet need for dental care (OR 0.29, 95% CI 0.16 to 0.53), prescribed medicines (OR 0.38, 95% CI 0.17 to 0.82) and mental healthcare (OR 0.17, 95% CI 0.05 to 0.61) compared with income between the first and second quintiles.ConclusionsRecent and planned reforms to address waiting times and financial barriers to accessing healthcare may help to address unmet need. In addition, policy-makers should consider additional policies targeted at high-risk groups with poor health and low incomes.

IntroductionThe COVID-19 pandemic has caused unprecedented disruptions around the world. Adding to the existing stress surrounding pregnancy and childbirth, the threat of infection and social isolation policies may negatively impact pregnant women and new mothers. Literature on the effect of COVID-19 on fear during pregnancy and childbirth experience is limited. As the COVID-19 pandemic continues to affect the global population, it is important to understand how it has impacted pregnant women and new mothers’ experiences worldwide to inform perinatal care and interventions.Methods and analysisThis multicountry study involving China and Canada targets to recruit 1000 pregnant women and new mothers who gave birth since 2020 in each participating country. Participants will be recruited online in the local language through mothers’ groups, antenatal and postnatal clinics and hospital wards. All questionnaires will be completed online. Participants’ level of fear, depression and childbirth experience will be assessed along with other sociodemographic, medical and COVID-related measures. Regression models will be used to compare the outcomes among the participating countries.Ethics and disseminationThe study has been reviewed and approved by the institutional review boards of the participating countries. Findings will be disseminated in peer-reviewed journals and academic conferences. Results from this study may guide the formulation of future health guidelines and policies in the face of a pandemic.

ObjectiveTo identify the availability, prices and affordability of essential medicines for children (cEMs) in Hanam province, Vietnam.DesignCross-sectional study.SettingOne city and five districts of Hanam province.Participants66 public health facilities and 66 private drugstores.Primary and secondary outcome measuresThe standardised methodology of the WHO and Health Action International was used to investigate 30 paediatric essential medicines. For each medicine, data were collected for two products: the lowest-priced medicine (LPM) and the highest-priced medicine (HPM). The availability of medicine was computed as the percentage of facilities in which this medicine was found on the day of data collection. Median prices of individual medicines were reported in local currency. Affordability was calculated as the number of days’ wages required for the lowest-paid unskilled government worker to purchase standard treatments for common diseases. Data were analysed using R software V.4.1.0.ResultsThe mean availability of LPMs in the private sector (33.2%, SD=38.0%) was higher than that in the public sector (24.9%, SD=39.4%) (p<0.05). The mean availability of HPMs was extremely low in both sectors (11.3% and 5.8%, respectively). The mean availability of cEMs in urban areas was significantly higher than that in rural areas (36.5% and 31.6%, respectively, p<0.05). In the public sector, the prices of LPMs were nearly equal to the international reference prices (IRPs). In the private sector, LPMs were generally sold at 4.06 times their IRPs. However, in both sectors, the affordability of LPMs was reasonable for most conditions as standard treatments only cost a day’s wage or less.ConclusionThe low availability was the main reason hindering access to cEMs in Hanam, especially in the countryside. A national study on cEMs should be conducted, and some practical policies should be promulgated to enhance access to cEMs.

Published: August 2021

IntroductionStatin-associated muscle symptoms (SAMSs) are a major clinical issue in the primary and secondary prevention of cardiovascular events. Current guidelines advise various approaches mainly based on expert opinion. We will lead a systematic review and meta-analysis to explore the tolerability and acceptability and effectiveness of statin-based therapy management of patients with a history of SAMS. We aim to provide evidence on the tolerability and different strategies of statin-based management of patients with a history of SAMS.Methods and analysisWe will conduct a systematic review of randomised controlled trials (RCTs) and non-randomised studies with a control group. We will search in Data sources MEDLINE, EMBASE, Cochrane Central Register of Controlled Clinical Trials, Scopus, Clinicaltrials.gov and Proquest from inception until April 2021. Two independent reviewers will carry out the study selection based on eligibility criteria. We will extract data following a standard data collection form. The reviewers will use the Cochrane Collaboration’s tools and Newcastle-Ottawa Scale to appraise the study risk of bias. Our primary outcome will be tolerability and our secondary outcomes will be acceptability and effectiveness. We will conduct a qualitative analysis of all included studies. In addition, if sufficient and homogeneous data are available, we will conduct quantitative analysis. We will synthesise dichotomous data using OR with 95% CI and continuous outcomes by using mean difference or standardised mean difference (with 95% CI). We will determine heterogeneity visually with forest plots and quantitatively with I2and Q-test. We will summarise the confidence in the quantitative estimate by using Grading of Recommendations Assessment, Development and Evaluation approach.Ethics and disseminationAs a systematic review of literature without collection of new clinical data, there will be no requirement for ethical approval. We will disseminate findings through peer-reviewed publications.PROSPERO registration numberCRD42020202619.

IntroductionFailure of early identification of sepsis in the emergency department (ED) leads to significant delays in antibiotic administration which adversely affects patient outcomes.AimThe primary objective of our Quality Improvement (QI) project was to reduce the door-to-antibiotic time (DTAT) by 30% from the preintervention in patients with suspected sepsis. Secondary objectives were to increase the blood culture collection rate by 30% from preintervention, investigate the predictors of improving DTAT and study the effect of these interventions on 24-hour in-hospital mortality.MethodsThis QI project was conducted in the ED of a tertiary care teaching hospital of North India; the ED receives approximately 400 patients per day. Adult patients with suspected sepsis presenting to our ED were included in the study, between January 2019 and December 2020. The study was divided into three phases; preintervention phase (100 patients), intervention phase (100 patients) and postintervention phase (93 patients). DTAT and blood cultures prior to antibiotic administration was recorded for all patients. Blood culture yield and 24-hour in-hospital mortality were also recorded using standard data templates. Change ideas planned by the Sepsis QI Team were implemented after conducting plan-do-study-act cycles.ResultsThe median DTAT reduced from 155 min in preintervention phase to 78 min in postintervention phase. Drawing of blood cultures prior to antibiotic administration improved by 67%. Application of novel screening tool at triage was found to be an independent predictor of reduced DTAT.ConclusionOur QI project identified the existing lacunae in implementation of the sepsis bundle which were dealt with in a stepwise manner. The sepsis screening tool and on-site training improved care of patients with sepsis. A similar approach can be used to deal with complex quality issues in other high-volume low-resource settings.

Published: August 2021

Administration of first dose of antibiotics within the golden hour in infants with sepsis is critical. Delays can increase mortality. During our observations as part of antibiotic stewardship programme in inborn neonatal unit, we found a significant delay in the administration of first dose of antibiotics from the decision time. We set up a quality improvement team to improve the proportion of neonates with sepsis, who received first dose of antibiotics within 1 hour of decision, from 0% to 80% over 2 months.We included inborn neonates requiring initiation or upgradation of antibiotics for a diagnosis of sepsis, from 1 May to 30 November 2018. We assessed the root causes behind delayed administration and found the lack of immediate availability of blood culture bottles, lack of awareness and busy clinical area as the major contributors to the delays in first dose. Various change ideas like ensuring prior availability of blood culture bottles, sensitising nursing staff and resident doctors, utilisation of hospital attendants and sharing responsibility of drawing culture between team members were tested through plan–do–study–act (PDSA) cycles.The proportion of neonates receiving first dose of antibiotics within 1 hour increased from 0% to 91% over the study period and was sustained at 92% after 6 months. There was a significant reduction in median (IQR) time interval between decision and first dose from 120 (100–290) to 45 (30–60) min (p<0.001) and after 6 months, it further decreased to 30 (30–45) min. We achieved significant improvement in administration of first dose of antibiotics within 1 hour of decision, by using system analysis and testing change ideas in sequential PDSA cycles.

ObjectiveAltered metabolites are important for the tumourigenicity of hepatocellular carcinoma (HCC). We performed integrative metabolomics analysis of the metabolites changes in portal venous blood and in comparison with the metabolites changes in liver tissues and stool samples of HCC patients and healthy liver donors.DesignSerum (portal and central vein), liver tissue (HCC tumour and adjacent non-tumour, normal liver) and stool samples were collected from 102 subjects (52 HCC patients and 50 healthy controls) in the discovery cohort; and 100 subjects (50 HCC patients and 50 healthy controls) in an independent validation cohort. Untargeted metabolomic profiling was performed using high-performance liquid chromatography-mass spectrometry. The function of candidate metabolites was validated in hepatocyte cell lines.ResultsDetailed metabolomic evaluation showed distinct clusters of metabolites in serum, liver tissue and stool samples from patients with HCC and control individuals (p<0.001). HCC patients had significantly higher levels of portal vein serum and HCC tissue metabolites of DL-3-phenyllactic acid, L-tryptophan, glycocholic acid and 1-methylnicotinamide than healthy controls, which were associated with impaired liver function and poor survival. On the other hand, HCC patients had lower levels of linoleic acid and phenol in portal vein and stool samples than healthy controls. Linoleic acid and phenol significantly inhibited HCC proliferation, inferring their anti-HCC function as protective metabolites.ConclusionsThe integrative metabolome analysis of serum, tissue and stool metabolites revealed unreported metabolic alterations in HCC patients. In portal vein, we identified elevated and depleted metabolites signifying that they might play a role in HCC development.
Nested sampling for materials
Authors: Pártay Livia B. , Csányi Gábor , Bernstein Noam 
Published: August 2021

AbstractWe review the materials science applications of the nested sampling (NS) method, which was originally conceived for calculating the evidence in Bayesian inference. We describe how NS can be adapted to sample the potential energy surface (PES) of atomistic systems, providing a straightforward approximation for the partition function and allowing the evaluation of thermodynamic variables at arbitrary temperatures. After an overview of the basic method, we describe a number of extensions, including using variable cells for constant pressure sampling, the semi-grand-canonical approach for multicomponent systems, parallelizing the algorithm, and visualizing the results. We cover the range of materials applications of NS from the past decade, from exploring the PES of Lennard–Jones clusters to that of multicomponent condensed phase systems. We highlight examples how the information gained via NS promotes the understanding of materials properties through a novel way of visualizing the PES, identifying thermodynamically relevant basins, and calculating the entire pressure–temperature(–composition) phase diagram.Graphic abstract
