ObjectivesParent carers of children with special educational needs or disability are at risk of poorer mental and physical health. In response to these needs, we codeveloped the ‘Healthy Parent Carers’ (HPC) programme. This study examined the views and experiences of participants in the HPC feasibility trial to inform programme refinement.Intervention, setting and participantsHPC is a peer-led group-based intervention (supported by online materials) for primary carers of disabled children, encouraging behaviours linked with health and well-being. It was delivered by two lead and six assistant peer facilitators in six community sites (one lead and one assistant per group) in South West England over six or 12 sessions. Control participants had online materials only. The trial involved 47 intervention and 45 control parent carers (97% female and 97% white) and eight facilitators (one male).DesignA preplanned mixed methods process evaluation using questionnaires and checklists (during and after the intervention), qualitative interviews with participants after intervention (n=18) and a focus group with facilitators after trial.ResultsHPC was highly acceptable to participants and facilitators and experiences were very positive. Participants reported that the programme increased awareness of what parent carers could and could not change and their self-efficacy to engage in health-promoting behaviours. The intended mechanisms of action (social identification and peer support) matched participants’ expectations and experiences. Control participants found the online-only programme flexible but isolating, as there were no opportunities to share ideas and problem solve with peers, the key function of the programme. Areas for improvement were identified for programme content, facilitator training and delivery.ConclusionHPC was acceptable, well received and offers considerable potential to improve the health of parent carers. Under the pandemic, the challenge going forward is how best to maintain reach and fidelity to function while delivering a more virtual programme.Trial registration numberISRCTN15144652.

Published: August 2021

ObjectivesThe objective was to determine the predictive potential of anthropometric indices to screen prevalent diabetes mellitus type 2 in a Norwegian population.DesignThis is a cross-sectional design to determine the potential association of waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), waist circumference (WC) and body mass index (BMI) with prevalent diabetes mellitus type 2 through logistic regression analysis. Receiver operating characteristic (ROC) curves were used to determine the predictive potential of the anthropometric indices. Youden’s index was applied to determine the optimal cut-off points for each anthropometric index.SettingThis study used cross-sectional data from the populations-based Health Study in Nord-Trøndelag which invited all citizens in the county above 20 years of age.ParticipantsThis study included all those who were non-pregnant and had complete data (N=50 042), 98.5% of the participants. The sample is to be considered representative for the population of Norway.Primary and secondary outcome measuresOR and ROC of the potential association between diabetes mellitus type 2 and anthropometric indices were the main planned and performed outcome measures.ResultsThe results suggest that the anthropometric indices performed differently within the Norwegian population with WHR and WHtR being the stronger predictor with (ROC) of 0.746 (0.735 to 0.757) and 0.741 (0.730 to 0.752). The predictive potential for the investigated anthropometric indices was generally stronger for women than men.ConclusionAnthropometric indices of size BMI and the highly correlated WC are less associated with prevalent diabetes mellitus type 2 than WHR (WC adjusted for hip circumference) or WHtR (WC adjusted for height) in a Norwegian population.

ObjectiveThe association of non-steroidal anti-inflammatory drugs with postoperative acute kidney injury (AKI) is controversial. However, there are few studies focusing on the association between parecoxib and postoperative AKI. Our study aimed at the possible correlation between the intraoperative administration of cyclooxygenase-2 inhibitors parecoxib and perioperative AKI.DesignA retrospective cohort study.SettingThird Xiangya Hospital of Central South University in Hunan Province, China.ParticipantsThe electronic medical records and laboratory results were obtained from 9246 adult patients (18–60 years) undergoing non-cardiac surgery performed between 1 January 2012 and 31 August 2017. Study groups were treated with or without parecoxib.InterventionsUnivariable analysis identified demographic, preoperative laboratory and intraoperative factors associated with AKI. Logistic stepwise regression was used to calculate the adjusted OR of parecoxib and AKI association.ResultsThe incidence of AKI was lower in the parecoxib-administered group (4%) than that in the group without parecoxib (6.3%, p=0.005). In the multivariable regression analysis, postoperative AKI risk reduced by 39% (OR 0.61; 95% CI 0.43 to 0.87) in the parecoxib-administered group after adjusting for interference factors. Sensitivity analysis showed that postoperative AKI risk reduced in four subgroups: eGRF <90 mL/min·1.73/m2(OR 0.49; 95% CI 0.29 to 0.82), non-smoker (OR 0.55; 95% CI 0.37 to 0.83), blood loss <1000 mL (OR 0.55; 95% CI 0.37 to 0.83) and non-hypotension (OR 0.57; 95% CI 0.38 to 0.84).ConclusionsThus, parecoxib is associated with a modest reduction of postoperative AKI risk among adult patients undergoing non-cardiac surgery.

Published: August 2021

ObjectivesCarer’s self-initiated management strategies of behavioural and psychological symptoms of dementia (BPSD) can inform intervention development. These strategies are affected by cultural values. Little is known about non-Western dementia carers’ BPSD management strategies. This study aimed to explore self-initiated strategies in managing BPSD adopted by Chinese carers.DesignQualitative study using thematic framework method.SettingCommunity setting in Hong Kong.Participants16 dementia carers with purposive sampling to include carers of different relationships to the people living with dementia (PLwD), education level and living arrangement.ResultsSix overarching themes emerged from the data: (1) maintaining personhood in PLwD, (2) responding positively to BPSD, (3) explanation and bargaining, (4) responding negatively to BPSD, (5) controlling upsetting thoughts, and (6) getting respite care. Chinese carers treasured warm and supportive family relationships. They identified and minimised triggers to alleviate BPSD. Some carers struggled with care tasks and reacted with confrontation and avoidance. Changing attitudes and getting social and emotional support were described to manage carers’ distress. Few self-care strategies including getting respite care were reported.ConclusionsCarers’ self-initiated strategies largely aligned with existing theoretical frameworks in BPSD management, such as person-centred approach, and echoed Asian culture, which advocates filial piety and supportive family relationships. While these cultural values encourage the engagement of people living with dementia in the normal process of family life, they may also prevent carers from taking time away from care. Interventions could support carers by enhancing their knowledge and skills in managing BPSD, providing social and emotional support, and providing guidance in self-care. Future cross-cultural research could explore factors contributing to how carers manage BPSD and how interventions could be culturally adapted to facilitate carers to apply learnt skills in daily practice and hence benefit the people living with dementia and carer population.

ObjectiveTo obtain insight into experiences of patients with a neuromuscular disease and chronic fatigue and their healthcare professionals regarding content and delivery of a multidisciplinary outpatient self-management group programme to improve social participation. This will inform future implementation.DesignA mixed method study alongside a randomised controlled trial.SettingUniversity hospital, rehabilitation centre and community health centre.Participants29 patients with a neuromuscular disease and chronic fatigue and 13 healthcare professionals participated in this mixed methods study.InterventionMultidisciplinary group programme, called Energetic, consisted of a 4 months intervention with weekly meetings and covered four modules: (1) individually tailored aerobic exercise training; (2) education about aerobic exercise; (3) self-management training in applying energy conservation strategies and (4) implementation and relapse prevention in daily life.Main measuresQuantitative data were collected by a questionnaire measuring patients’ (n=25, all completed the programme) satisfaction with the perceived results, content and delivery of the programme. Qualitative data were collected by individual and focus group interviews to gain insight in the experiences of patients (n=18), next of kin (n=2) and healthcare professionals (n=13) with facilitators and barriers to programme implementation.ResultsPatients were satisfied with the number and length of the sessions, the different modules and the therapists. Analysis of the interviews led to five themes: (1) the combination of modules makes a complete picture, (2) the programme is physically and mentally intensive, (3) the group setting is valuable, (4) small variations in delivery occur in different settings, (5) therapists are coaches. Suggestions for programme improvement include a combination of face to face and e-health, enhancement of therapists’ skills in guiding group interventions and inclusion of more booster sessions to evaluate and maintain self-management competencies.ConclusionsThe Energetic programme could be implemented in different healthcare settings and group settings, and a combination of modules proved to be a facilitator for improving self-management.Trial registration numberNCT02208687.

Published: August 2021

IntroductionPolycystic ovary syndrome (PCOS) is one of the most common endocrinopathy in women of reproductive age. Recently, moxibustion, as a complementary and alternative therapy, has been commonly used in assisted reproduction and improvement of metabolic abnormalities in patients with PCOS. Currently, intervention efficacy of the use of moxibustion in PCOS treatment still remains controversial due to lack of high-quality evidence. Consequently, this study protocol was designed to objectively review and evaluate the effectiveness and safety of moxibustion treatment for PCOS.Methods and analysisElectronic searches will be carried out from inception to May 2021 in the online databases of The Cochrane Library, PubMed, EMBASE, Chinese Biomedical Literature, Chongqing VIP Chinese Science and Technology Periodical Database (VIP) and China National Knowledge Infrastructure. The Chinese Clinical Trial Registry Center and Clinical Trials will be used for searching ongoing trials. Randomised controlled trials and the first period in randomised cross-over trials involving any type of moxibustion for patients with PCOS will be included. Primary outcomes will be the ovulation rate, pregnancy rate and sex hormone levels, and secondary outcomes will be changes in clinical symptoms and metabolic indicators, total effective rate and the incidences of side effects and adverse events. Briefly, two reviewers will independently conduct study selection and data extraction, and the risk of bias will be assessed. Prior to the formal meta-analysis, the heterogeneity of included studies will be assessed. Review Manager Statistical Software (RevMan) V.5.3 will be used for data processing. Finally, the Grading of Recommendations Assessment, Development and Evaluation method will be applied to evaluate the quality of evidence.Ethics and disseminationEthical approval is not necessary since this study is designed as a systematic review. This study will be disseminated by a peer-review journal or conference presentation.
Does knowledge of the primary tumour affect survival after surgery for spinal metastatic disease? A retrospective longitudinal cohort study
Authors: Carrwik Christian , Olerud Claes , Robinson Yohan 
Published: August 2021

ObjectivesTo compare survival after surgery for patients with spinal metastatic disease with known primary tumour (KPT) versus patients with unknown primary tumour (UPT).Participants393 patients 18 years or older (270 men and 123 women, mean age 67.3 years) undergoing surgery at Uppsala University Hospital in Swedenbetween 2006 and 2016due to spinal metastatic disease . 271 patients (69%) had a KPT at the time of surgery and 122 (31%) had an UPT.InterventionsDecompressive and/or stabilising spine surgery due to spinal metastatic disease.Primary outcomeSurvival (median and mean) after surgery.ResultsThe estimated median survival time after surgery for patients with KPT was 7.4 months (95% CI 6.0 to 8.7) and mean survival time was 21.6 months (95% CI 17.2 to 26.0). For patients with UPT, the median estimated survival time after surgery was 15.6 months (95% CI 7.5 to 23.7) and the mean survival time was 48.1 months (95% CI 37.3 to 59.0) (Breslow, p=0.001). Unknown primary cancer was a positive predictor of survival after surgery (Cox regression, HR=0.58, 95% CI 0.46 to 0.73).ConclusionIn this study, patients with spinal metastasis and UPT had a longer expected survival after surgery compared with patients with KPT. This suggests that patients with UPT and spinal metastasis should not be withheld from surgery only based on the fact that the primary tumour is unknown.

Published: August 2021

BackgroundEffective teamwork between anaesthesiologists and surgeons is essential for optimising patient safety in the cardiac operating room. While many factors may influence the relationship between these two physicians, the role of sex and gender have yet to be investigated.ObjectivesWe sought to determine the association between cardiac physician team sex discordance and patient outcomes.DesignWe performed a population-based, retrospective cohort study.Participants and settingAdult patients who underwent coronary artery bypass grafting (CABG) and/or aortic, mitral or tricuspid valve surgery between 2008 and 2018 in Ontario, Canada.Primary and secondary outcome measuresThe primary outcome was all-cause 30-day mortality. Secondary outcomes included major adverse cardiovascular events at 30 days and hospital and intensive care unit lengths of stay (LOS). Mixed effects logistic regression was used for categorical outcomes and Poisson regression for continuous outcomes.Results79 862 patients underwent cardiac surgery by 98 surgeons (11.2% female) and 279 anaesthesiologists (23.3% female); 19 893 (24.9%) were treated by sex-discordant physician teams. Physician sex discordance was not associated with overall patient mortality or LOS; however, patients who underwent isolated CABG experienced longer hospital LOS when treated by an all-male physician team as compared with an all-female team (adjusted OR=1.07; p=0.049). When examining the impact of individual physician sex, the length of hospital stay was longer when isolated CABG procedures were attended by a male surgeon (OR=1.10; p=0.004) or anaesthesiologist (OR=1.02; p=0.01).ConclusionsPatient mortality and length of stay after cardiac surgery may vary by sex concordance of the attending surgeon–anaesthesiologist team. Further research is needed to examine the underlying mechanisms of these observed relationships.

Heart rate variability (HRV) measurement provides non-invasive assessment of autonomic stability and cardiometabolic disease risk. Insufficient physical activity in early childhood may contribute to negative cardiometabolic health. The Active Early Learning (AEL) study was a 6-month randomised controlled trial investigating the effects of a physical activity-based program incorporating movement within the daily curriculum of preschool children. The current study assessed the effects of the AEL intervention on HRV as a measure of cardiac vagal control. Children aged between 3–5 years and enrolled in a preschool with an attendance of ≥15 children were eligible. Physical activity was recorded using an Actigraph wGT3x accelerometer worn at the waist of participants over 3 consecutive days. A Polar H10 chest strap measured HRV with the HF-band and RMSSD representing cardiac vagal control. After 6 months of the AEL trial, linear mixed model analyses revealed a significant intervention effect for increased HF (p = 0.044). The control group did not demonstrate changes in cardiac vagal control after the intervention ceased. Independent of age, sex, physical activity and BMI, the AEL study elicited significant improvements in the cardiac vagal control of participants who received the intervention. Findings highlight the importance of investigating HRV for assessing the cardiometabolic health in young children. ANZCTR trial registration number: ACTRN12619000638134. Novelty: The AEL curriculum improved child HRV independent of age, sex, physical activity and BMI. Heart rate and RR intervals did not demonstrate changes for the intervention and control groups. Multivariate programs for developing physical competence, confidence, knowledge and motivation may improve child health.

Type 2 diabetes occurs as a result of insulin resistance and dysfunction in insulin signaling. Controlling hyperglycemia and activation of insulin signaling are important in the management of type 2 diabetes. This study aimed to evaluate the effect of genistein and Momordica charantia L. fruit (MCF) on oxidative stress, markers of inflammation, and their role in proglucagon and insulin receptor messenger RNA (mRNA) expression by real-time PCR in diabetic rats. Thirty-five albino rats were divided into 7 groups (n = 5). Group I (non-diabetic) and group II (diabetic control) were treated with distilled water, and groups III and IV received 250 mg/kg and 500 mg/kg lyophilized MCF, respectively. Groups V and VI received 10 mg/kg and 20 mg/kg genistein, respectively, while group VII received 500 mg/kg metformin. The administration lasted for 28 days. MCF and genistein significantly reduced interleukin (IL)-1β and tumor necrosis factor alpha (TNF-α) levels, which were elevated in the serum of diabetic rats. Treatment with MCF and genistein significantly increased the expression of proglucagon mRNA in the small intestine and insulin receptor mRNA in the liver of diabetic rats. In conclusion, MCF and genistein ameliorate type 2 diabetes complications by preventing the loss of insulin-positive cells, inhibiting IL-1β and TNF-α, and upregulating proglucagon and insulin receptor mRNA expression. Novelty: MCF and genistein have an inhibitory effect on diabetic induced IL-1β and TNF-α production. MCF and genistein upregulate proglucagon and insulin receptor mRNA expression.

AbstractEpithelial ovarian carcinomas are particularly deadly due to intratumoral heterogeneity, resistance to standard-of-care therapies, and poor response to alternative treatments such as immunotherapy. Targeting the ovarian carcinoma epigenome with DNA methyltransferase inhibitors (DNMTi) or histone deacetylase inhibitors (HDACi) increases immune signaling and recruits CD8+ T cells and natural killer cells to fight ovarian carcinoma in murine models. This increased immune activity is caused by increased transcription of repetitive elements (RE) that form double-stranded RNA (dsRNA) and trigger an IFN response. To understand which REs are affected by epigenetic therapies in ovarian carcinoma, we assessed the effect of DNMTi and HDACi on ovarian carcinoma cell lines and patient samples. Subfamily-level (TEtranscripts) and individual locus-level (Telescope) analysis of REs showed that DNMTi treatment upregulated more REs than HDACi treatment. Upregulated REs were predominantly LTR and SINE subfamilies, and SINEs exhibited the greatest loss of DNA methylation upon DNMTi treatment. Cell lines with TP53 mutations exhibited significantly fewer upregulated REs with epigenetic therapy than wild-type TP53 cell lines. This observation was validated using isogenic cell lines; the TP53-mutant cell line had significantly higher baseline expression of REs but upregulated fewer upon epigenetic treatment. In addition, p53 activation increased expression of REs in wild-type but not mutant cell lines. These data give a comprehensive, genome-wide picture of RE chromatin and transcription-related changes in ovarian carcinoma after epigenetic treatment and implicate p53 in RE transcriptional regulation.Significance:This study identifies the repetitive element targets of epigenetic therapies in ovarian carcinoma and indicates a role for p53 in this process.See interview with Katherine B.
