IntroductionThis paper describes the protocol for an ongoing project funded by the Royal Society, the Resilience After Individual Stress Exposure (RAISE) study; which aims to examine the factors and mechanisms that facilitate resilient functioning after childhood adversity (CA).Methods and analysisWe aim to recruit up to 200 participants. We will use dimension reduction techniques (principal component analysis) on standard-normally transformed individual parameters of mental health, social functioning and CA to calculate a composite measure of adaptive (ie, ‘resilient’) psychosocial functioning. To examine the neuroimmune responses to stress and their relationship with the brain and social environment, we will use a well validated functional MRI task; the Montreal imaging stress task and venepuncture. We will run group or dimensional comparisons in multiple levels of biological and psychological outcomes, as well as mediation and moderation analyses to study how key biological systems (ie, the hypothalamic–pituitary–adrenal axis and the immune system) interrelate and interact with brain function and social influences in order to facilitate resilient functioning after CA. We hypothesise that resilient functioning will be facilitated by reduced morning cortisol and cytokine levels before and after the stressor and improved neural responses to such stress, as well as increased gray matter volume in the hippocampus and prefrontal cortex, enhanced inhibitory control and emotion regulation, and more friendship and family support.Ethics and disseminationThis study has been reviewed and given favourable opinion by the National Research Ethics Service, NRES Committee East of England-Cambridge Central and external reviewers from the Royal Society (RGF\R1\180064 and RGF\EA\180029). The results of the RAISE study will be disseminated through (1) publications in scientific peer reviewed journals, (2) presentations on relevant scientific conferences and meetings, (3) publications and presentations for the general public and (4) through social media.

ObjectivesInnovative methods are needed for identification of transgender people in administrative records for health research purposes. This study investigated the feasibility of using transgender-specific healthcare utilisation in a Canadian population-based health records database to develop a computable phenotype (CP) and identify the proportion of transgender people within the HIV-positive population as a public health priority.DesignThe Comparative Outcomes and Service Utilization Trends (COAST) Study cohort comprises a data linkage between two provincial data sources: The British Columbia (BC) Centre for Excellence in HIV/AIDS Drug Treatment Program, which coordinates HIV treatment dispensation across BC and Population Data BC, a provincial data repository holding individual, longitudinal data for all BC residents (1996–2013).SettingBritish Columbia, Canada.ParticipantsCOAST participants include 13 907 BC residents living with HIV (≥19 years of age) and a 10% random sample comparison group of the HIV-negative general population (514 952 individuals).Primary and secondary outcome measuresHealthcare records were used to identify transgender people via a CP algorithm (diagnosis codes+androgen blocker/hormone prescriptions), to examine related diagnoses and prescription concordance and to validate the CP using an independent provider-reported transgender status measure. Demographics and chronic illness burden were also characterised for the transgender sample.ResultsThe best-performing CP identified 137 HIV-negative and 51 HIV-positive transgender people (total 188). In validity analyses, the best-performing CP had low sensitivity (27.5%, 95% CI: 17.8% to 39.8%), high specificity (99.8%, 95% CI: 99.6% to 99.8%), low agreement using Kappa statistics (0.3, 95% CI: 0.2 to 0.5) and moderate positive predictive value (43.2%, 95% CI: 28.7% to 58.9%). There was high concordance between exogenous sex hormone use and transgender-specific diagnoses.ConclusionsThe development of a validated CP opens up new opportunities for identifying transgender people for inclusion in population-based health research using administrative health data, and offers the potential for much-needed and heretofore unavailable evidence on health status, including HIV status, and the healthcare use and needs of transgender people.

ObjectiveWe aimed to detect the incidence and risk factors of type 2 diabetes mellitus (T2DM) development in the suburbs of Beijing.DesignCohort study with record linkage to incidence data.SettingWe performed a 5-year follow-up study in a randomly selected suburban population including 1114 subjects aged ≥18 years living in the suburbs of Beijing.Participants118 subjects with T2DM at baseline according to the 1999 WHO criteria were excluded, and 895 subjects attended the follow-up assessment in 2012. The non-diabetic subjects at baseline were classified into two groups: normal glucose tolerance (NGT) group (n=673) and impaired glucose regulation (IGR) group(n=222).The incidence and risk factors of diabetes development in each group were investigated.Outcome measuresA structured questionnaire about sociodemographic characteristics, height, weight, waist circumference, hip circumference, blood pressure, oral glucose tolerance test and serum lipid levels.ResultsOut of the 895 non-diabetic subjects, 67 developed diabetes with 29 in the NGT group and 38 in the IGR group, respectively, after a 5-year follow-up, producing an overall 5-year cumulative incidence of diabetes of 13%. The incidence of diabetes was 15.5 cases per 1000 person-years, 8.9 cases per 1000 person-years in the NGT group and 35.7 cases per 1000 person-years in the IGR group (p<0.01; RR 4.03; 95% CI 2.58 to 9.29). Binary logistic regression analysis showed that the risk factors for diabetes development included fasting plasma glucose (FPG) in the NGT group, and sex, the waist-to-hip ratio, FPG and diastolic blood pressure (DBP) in the IGR group.ConclusionsDuring a mean follow-up of 5.0 years, the incidence of T2DM in the suburbs of Beijing was 15.5 per 1000 person-years. Early prevention of diabetes should focus on IGR subjects. Elevated FPG predicted diabetes development for both NGT and IGR subjects. Female sex, overweight/obesity and DBP are risk factors for diabetes development in IGR subjects.

Published: October 2022

ObjectiveTo provide a general overview of the reported current surgical capacity and delivery in order to advance current knowledge and suggest targets for further development and research within the region of sub-Saharan Africa.DesignScoping review.SettingDistrict hospitals in sub-Saharan Africa.Data sourcesPubMed and Ovid EMBASE from January 2000 to December 2019.Study selectionStudies were included if they contained information about types of surgical procedures performed, number of operations per year, types of anaesthesia delivered, cadres of surgical/anaesthesia providers and/or patients’ outcomes.ResultsThe 52 articles included in analysis provided information about 16 countries. District hospitals were a group of diverse institutions ranging from 21 to 371 beds. The three most frequently reported procedures were caesarean section, laparotomy and hernia repair, but a wide range of orthopaedics, plastic surgery and neurosurgery procedures were also mentioned. The number of operations performed per year per district hospital ranged from 239 to 5233. The most mentioned anaesthesia providers were non-physician clinicians trained in anaesthesia. They deliver mainly general and spinal anaesthesia. Depending on countries, articles referred to different surgical care providers: specialist surgeons, medical officers and non-physician clinicians. 15 articles reported perioperative complications among which surgical site infection was the most frequent. Fifteen articles reported perioperative deaths of which the leading causes were sepsis, haemorrhage and anaesthesia complications.ConclusionDistrict hospitals play a significant role in sub-Saharan Africa, providing both emergency and elective surgeries. Most procedures are done under general or spinal anaesthesia, often administered by non-physician clinicians. Depending on countries, surgical care may be provided by medical officers, specialist surgeons and/or non-physician clinicians. Research on safety, quality and volume of surgical and anaesthesia care in this setting is scarce, and more attention to these questions is required.

BackgroundIn sub-Saharan Africa (SSA), millions of pregnant women are exposed to malaria infection. The cornerstone of the WHO strategy to prevent malaria in pregnancy in moderate to high-transmission areas is the administration of intermittent preventive treatment (IPTp) with sulfadoxine-pyrimethamine at each scheduled antenatal care (ANC) visit. However, overall coverage remains low. ‘Transforming IPT for Optimal Pregnancy’ (TIPTOP) project aims at delivering IPTp at the community level (C-IPTp) to complement ANC provision with the goal of increasing IPTp coverage and improving maternal and infant’s health. This protocol describes the approach to measure the effect of this strategy through household surveys (HHS) in four SSA countries: Democratic Republic of Congo (DRC), Madagascar, Mozambique and Nigeria.Methods and analysisA quasi-experimental evaluation has been designed. Delivery of C-IPTp will start first in one area per country, and later it will be extended to two more areas per country. HHS will be carried out before C-IPTp implementation in all study sites, at midterm in initial implementation areas, and after the implementation in all project areas. A multistage cluster sampling method will be followed for the selection of participants. Women of reproductive age who had a pregnancy that ended in the 6 or 12 months prior to the interview, depending on the survey, will be invited to participate by responding to a questionnaire. The main indicators will be coverage of three or more doses of IPTp and attendance to at least four ANC visits. A difference-in-difference analysis will be performed to evaluate the effectiveness of C-IPTp.Ethics and disseminationThe project has been reviewed by the ethics committees of WHO, Hospital Clinic of Barcelona and all project country boards. Project results will be disseminated to in-country stakeholders and at regional and international meetings. TIPTOP project aims to develop and disseminate global recommendations for C-IPTp delivery.Trial registration numberNCT03600844; Pre-results.

ObjectivesHyperhomocysteinemia is an independent risk factor for cardiovascular diseases. We aimed to investigate the prevalence and risk factors for hyperhomocysteinemia, especially modifiable lifestyle factors, such as smoking behaviour and dietary factors.DesignPopulation-based cross-sectional study.SettingHunan Province, ChinaParticipantsA total of 4012 participants completed the study, between July 2013 and March 2014. The median age is 55 (interquartile range: 45–63) years, with 1644 males (41%) and 2368 females (59%).Main outcome measuresHomocysteine level were measured by the microplate enzyme immunoassay method. Hyperthomocysteinemia was defined as ≥15 µmol/L. Questionnaire was used to investigate potential risk factors of hyperhomocysteinemia. Crude odd ratio (OR) or adjusted OR with 95% CI were determined by using univariable or multivariable logistic regression models.ResultsThe prevalence of hyperhomocysteinemia is 35.4% (45.4% vs 28.5% for men, women, respectively). One-year increase in age is significantly associated with 2% higher risk of hyperhomocysteinemia (OR=1.02, 95% CI: 1.01 to 1.03). One unit increase of BMI is associated with 5% higher risk of hyperhomocysteinemia (OR=1.05, 95% CI: 1.03 to 1.07). Compared with the non-smoker, smoking participants have a 24% higher risk of hyperhomocysteinemia (OR=1.24, 95% CI: 1.006 to 1.53), while the risk for those quitting smoking are not significantly different (OR=1.14, 95% CI: 0.85 to 1.54). compared with those consuming fruit and vegetable at least once every day, those consuming less than once every day had a significantly higher risk of hyperhomocysteinemia (OR=1.29, 95% CI:1.11 to 1.50). In addition, we found there were significant sex interaction with education level or alcohol drinking on the risk of hyperhomocysteinemia (pinteraction<0.05).ConclusionsHigher BMI and older age are potential risk factors for hyperhomocysteinemia. Current smoking but not quitting smoking is associated with higher risk of hyperhomocysteinemia. Fruit and vegetable consumption may have protective effect against hyperhomocysteinemia. Alcohol consumption or education level might interact to influence the risk of hyperhomocysteinemia.

ObjectiveReliance on webinars for continuing medical education (CME) has increased since the onset of the COVID-19 pandemic. Here, we aimed to evaluate the teaching methods used in these webinars.DesignRetrospective, longitudinal study.Setting20 CME-approved webinars, conducted March–December 2020 in Germany, and lasting 2.25 hours each.ParticipantsOtorhinolaryngologists pursuing CME credits.InterventionsPostwebinar participant assessments of the speaker, effects on practical work, desired scientific content, technical quality, interactions, attention and future training behaviour.ResultsOn average, 780 participants joined each webinar. The mean survey response rate was 35% (n=282). When asked how well the speaker had mastered the content, 38% responded ‘very well’, 44% responded ‘well’, 14% indicated ‘satisfactory’ and 4% chose ‘sufficient’. The frequency of webinars was considered appropriate by 92%, too high by 4% and too low by 4% of participants. The measured attention of the participants was 90%. After the COVID-19 pandemic lockdown, 68% of participants preferred online teaching. The average costs per participant were €3.50 (about $4.25 or £3.15) per webinar.ConclusionsAlthough the pandemic context likely influenced the results, we conclude that periodic ear, nose and throat webinar training during COVID-19 in 2020 was an effective alternative delivery method. We found high attention rates, high levels of participant satisfaction and low costs. Evaluations and re-evaluations will be necessary to adapt teaching concepts successfully and ensure high levels of teaching and learning efficiency.
MUKtwelve protocol: a phase II randomised, controlled, open, parallel group, multicentre trial of selinexor, cyclophosphamide and prednisolone (SCP) versus cyclophosphamide and prednisolone (CP) in patients with relapsed or refractory multiple myeloma

Published: October 2022

IntroductionMultiple myeloma is a malignancy of plasma cells with around 6000 new cases per year in the UK. Cyclophosphamide plus prednisolone is considered a standard of care for disease and symptom control in the advanced relapsed or refractory myeloma setting within the UK NHS. The selective nuclear export inhibitor, selinexor, has been relatively well tolerated in previous clinical trials and offers promise when used in combination with a wide range of other anti-cancer treatments. Here, we investigate if the addition of selinexor can improve responses to cyclophosphamide plus prednisolone without adding prohibitive toxicity.Methods and analysisMUKtwelve is a UK-based, randomised, controlled, open, parallel group, multicentre phase II trial designed to evaluate clinical efficacy of selinexor in combination with cyclophosphamide and prednisolone (SCP) in patients with relapsed or refractory multiple myeloma. A calibration arm will receive cyclophosphamide and prednisolone alone (CP). Participants who experience disease progression on the CP arm may, if eligible, receive SCP.The MUKtwelvetrial results will be the first to assess clinical efficacy of selinexor with low-dose CP in relapsed/refractory multiple myeloma. It is widely accepted that the relapsing-remitting nature of the disease is accompanied by cellular changes that often result in the requirement for novel agents and drug combinations to regain disease control. Patients also often experience cumulative toxicities throughout their treatments, limiting the treatment intensity that can be given at relapse. Thus, there is a need for novel effective combination therapies with acceptable toxicity profiles.Ethics and disseminationEthics approval is obtained. Results will be submitted for publication in a peer-reviewed journal.Trial registration numberISRCTN15028850.

Published: October 2022

IntroductionMany women experience symptoms during pregnancy. Elevated and prolonged anxiety can have negative effects on the woman and baby. The RAPID intervention aims to provide suitable, timely support for women with mild-moderate anxiety. The RAPID intervention is based on social support, relational continuity, psychological and relaxation response theory, and comprises midwife facilitated group discussions, one-to-one support and directed self-help materials.Methods and analysisFour National Health Service Trusts in England that provide maternity care will be cluster randomised to the RAPID intervention plus usual care or usual care. At each intervention site, two midwives and two maternity support workers will facilitate the intervention over a 12-week period. Eligibility includes nulliparous women at 16–20 weeks of pregnancy (n=50) with self-report symptoms of mild-moderate anxiety. Community midwives will signpost women to the study. The aim of the study is to establish the feasibility of conducting a definitive trial to examine the effectiveness of the RAPID intervention in addition to usual care. The objectives are to assess recruitment and completion rates, and a qualitative assessment of women’s and facilitators’ experiences of participation. An estimation of change in the seven-item Generalised Anxiety Disorder scale will inform the sample size for a definitive cluster trial.Ethics and disseminationEthical approval was given by East Midlands—Derby Research Ethics Committee 14 March 2022 (REC Reference: 22/EM/0018). Findings will be made available through publication in peer-reviewed journals, conferences and to participants. A final report will be submitted to HEE/NIHR ICA awards committee for publication.Trial registration numberISRCTN12834758.

Published: October 2022

IntroductionDepression is a common mental disorder and is a major cause of years lived with disability. The COVID-19 pandemic has caused an increase in the prevalence of depression worldwide. Our aim is to identify and synthesise the determinants of depression, the diagnostic assessment tools used to evaluate depression, and the interventions carried out since the beginning of the COVID-19 pandemic in the population aged 60 and older.Methods and analysisA systematic review of the literature will be conducted. The following databases will be searched: CINAHL Plus with Full Text, MedicLatina, MEDLINE with Full Text, and Psychology and Behavioural Sciences Collection. The search strategy will include the following Medical Subject Headings or similar terms: “Depression”, “Depressive Disorder”, “Depressive Symptoms”, “Older Adults”, “Aging”, “Elderly”, Pandemic” and “COVID-19”. Two independent reviewers will ascertain whether the resulting articles meet inclusion and exclusion criteria, and perform the analysis of data quality. Disagreements will be resolved by a third reviewer. All studies reported between December 2019 and March 2022 meeting the following criteria will be included: studies in adults aged 60 and over, and articles written in English, Portuguese, Spanish or German. Information on determinants of depression, assessment instruments used to assess depressive symptoms and/or interventions to decrease depression are reported. Studies will not be excluded based on geographical area study context (eg, community, culture or specific environment). All studies related to diagnostic assessment, care planning and/or intervention strategies specifically for older adults with depression will be included.Ethics and disseminationAs only secondary data will be analysed, no ethical approval is required for this study. This scientific article is a systematic review protocol for which data have not yet been extracted or analysed. The results will be disseminated through peer-reviewed publications.PROSPERO registration numberCRD42022299775.
