Abstract Aims We aimed to determine the association between serum interleukin‐6 (IL‐6) concentrations and new‐onset heart failure (HF) in persons with type 2 diabetes (T2D). Methods and results We performed a case–control study nested in the Diabetes Care System Cohort, a prospective cohort of persons with T2D in primary care. We included 724 participants, of whom 141 developed HF during 5 years of follow‐up and 583 were age‐ and sex‐matched controls. IL‐6 was measured at baseline and categorized into four groups: Group 1 was composed of participants with IL‐6 below the detection limit of 1.5 pg/mL, and the remainder were divided into tertiles. We performed logistic regression analyses with categorized IL‐6 or continuous IL‐6 as the determinant and new‐onset HF as the outcome adjusted for follow‐up time, age, sex, glycated haemoglobin, estimated glomerular filtration rate, albumin/creatinine ratio, and cardiovascular disease at baseline. Effect modification by sex was tested. Participants were 70.7 ± 9.0 years, and 38% were women. In comparison with Group 1, all tertiles were associated with an increased risk of HF with odds ratios of 2.1 [95% confidence interval (CI): 1.2–2.9], 2.8 (95% CI: 2.0–3.7), and 2.1 (95% CI: 1.3–3.0), respectively, for Tertiles 1–3. Continuous IL‐6 was associated with the development of HF with an odds ratio of 1.2 (95% CI: 1.0–1.5). No effect modification by sex was observed. Conclusions Higher IL‐6 levels are associated with the development of HF in persons with T2D. Further research should determine whether IL‐6‐lowering interventions could prevent the development of HF.

Computer Science - Information Theory - Abstract
Channel Reciprocity-based Key Generation (CRKG) exploits reciprocal channel randomness to establish shared secret keys between wireless terminals. This new security technique is expected to complement existing cryptographic techniques for secret key distribution of future wireless networks. In this paper, we present a new attack, reconfigurable intelligent surface (RIS) jamming, and show that an attacker can prevent legitimate users from agreeing on the same key by deploying a malicious RIS to break channel reciprocity. Specifically, we elaborate on three examples to implement the RIS jamming attack: Using active nonreciprocal circuits, performing time-varying controls, and reducing the signal-to-noise ratio. The attack effect is then studied by formulating the secret key rate with a relationship to the deployment of RIS. To resist such RIS jamming attacks, we propose a countermeasure that exploits wideband signals for multipath separation. The malicious RIS path is distinguished from all separated channel paths, and thus the countermeasure is referred to as contaminated path removal-based CRKG(CRP-CRKG). We present simulation results, showing that legitimate users under RIS jamming are still able to generate secret keys from the remaining paths. We also experimentally demonstrate the RIS jamming attack by using commodity Wi-Fi devices in conjunction with a fabricated RIS prototype. In our experiments, we were able to increase the average bit disagreement ratio (BDR) of raw secret keys by 20%. Further, we successfully demonstrate the proposed CRP-CRKG countermeasure to tackle RIS jamming in wideband systems as long as the source of randomness and the RIS propagation paths are separable., Comment: 15 pages, 14 figures

Abstract Background Older patients with type 2 diabetes mellitus (T2D) have an increased risk of hypoglycaemic episodes when using sulphonylureas or insulin. In the Netherlands, guidelines exist for reducing glucose-lowering medication in older patients. However, evidence is lacking that a medication reduction in older patients can be safely pursued. Here, we will examine if promoting the deprescribing of insulin/sulphonylureas with a deprescribing programme (DPP) in general practice affects T2D-complications in older overtreated patients. Methods We will perform a 1:1 cluster randomised controlled trial in 86 general practices in the Netherlands. The DPP will consist of education sessions with general practitioners and practice nurses about reducing glucose-lowering medication in older patients (≥ 70 years). Topics of the sessions include the necessity of deprescribing, tools to initiate deprescribing and strategies to discuss deprescribing with patients (shared decision making). The DPP further includes a support programme with practice visits. The study will employ a selection tool to identify possibly overtreated older patients from the electronic medical records of the general practitioner. Eligibility for enrolment in the study will be based on HbA1c targets indicated by the Dutch guidelines, which depend on age, diabetes duration, presence of frailty, and life expectancy. The control group will provide usual care. We aim to include 406 patients. The follow-up period will be 2 years. For the primary outcome, the effect of the DPP on T2D-complications will be assessed by counting the cumulative incidence of events related to under- and overtreatment in T2D as registered in the electronic medical records. We shall perform an intention-to-treat analysis and an analysis including only patients for whom deprescribing was initiated. The implementation of the DPP in general practice will be evaluated quantitatively and qualitatively using the Extended Normalisation Process Theory (ENPT) and the Reach, Efficacy – Adoption, Implementation and Maintenance (RE-AIM) model. Other secondary outcomes include quality of life, cognitive functioning, events related to overtreatment or undertreatment, biomarkers of health, amount of blood glucose-lowering medication prescriptions, and cost-effectiveness. Discussion This study will provide insight into the safety and feasibility of a programme aimed at deprescribing sulphonylureas/insulin in older people with T2D who are treated in general practice.

Abstract Background Social jetlag is a chronic disruption of sleep timing that is characterized by different sleep timing during workdays and free days. Social jetlag has been associated with disturbed glucose metabolism, insulin resistance, and increased risk of metabolic syndrome and type 2 diabetes. In this study, we aim to investigate whether a combination of bright light therapy in the morning, bright light reduction in the evening and sleep advance instructions for 3 weeks reduces social jetlag and if this results in improvement of glycemic and metabolic control, sleep, mood and quality of life after 3 and 12 weeks in people with prediabetes and type 2 diabetes and to assess possible mediators, compared to regular sleep habits. Methods In this randomized controlled trial, 60 people with prediabetes or type 2 diabetes with > 1 h social jetlag will be recruited. The intervention consists of bright light therapy (5000 lx) emitted by Vitamine-L (Lumie, UK) for 30 min each morning, combined with the advice to follow sleep advance instructions and to wear bright light-dimming goggles every evening for a period of 3 weeks. The control group adheres to their regular sleep habits and conditions. The primary outcome is glycated hemoglobin (HbA1c) after 12 weeks comparing the intervention and control in an intention-to-treat analysis. Secondary outcomes at 3 and 12 weeks are (1) social jetlag; (2) insulin sensitivity, fasting blood glucose, glucose-lowering medication use, and frequency of perceived hypoglycemia; (3) metabolic outcomes, including body mass index (BMI), waist circumference, body fat percentage, and blood pressure; (4) mood, including depression, fatigue and anxiety (measured with questionnaires); and (5) quality of life measured using EQ5D questionnaire. To assess other factors that might play a role as possible mediators, we will measure (para)sympathetic nervous system activity assessed with ECGs and electrochemical skin conductance tests, sleep quality and sleep phase distribution assessed with a sleep measuring headband (ZMax), the Dim Light Melatonin Onset in saliva samples (in a subgroup) at 3 and 12 weeks, the feeling of satiety and satiation with a 10-cm visual analog scale (VAS), diet using a food frequency questionnaire, and physical activity using an accelerometer (ActiGraph). Discussion Social jetlag can contribute to poorer glycemic control and metabolic control in those with type 2 diabetes. With this intervention, we aim to reduce social jetlag and thereby improve glycemic and metabolic control. This could offer a way to improve overall population health and to reduce the disease burden of type 2 diabetes. Trial registration ISRCTN registry ISRCTN11967109 . Registered on 9 May 2024.

Background: Subclinical thyroid diseases are often the subject of debate concerning their clinical significance, the appropriateness of diagnostic testing, and possible treatment. This systematic review addresses the variation in international guidelines for subclinical hyperthyroidism, focusing on diagnostic workup, treatment, and follow-up recommendations. Methods: Following the PRISMA guidelines, we searched PubMed, Embase, and guideline-specific databases and included clinical practice guidelines with recommendations on subclinical hyperthyroidism. Guideline recommendations were extracted, and quality assessment was performed using selected questions of the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument. Results: Of the 2624 records screened, 22 guidelines were included, which were published between 2007 and 2021. Guideline quality was generally intermediate to low. Diagnostic approaches differed substantially, particularly in the extent of recommended testing. Treatment initiation depended on TSH levels, age, and comorbidities, but the level of detail regarding defining precise comorbidities varied. Recommendations for monitoring intervals for follow-up ranged from 3 to 12 months. Conclusion: This review underscores the existing variability in (inter)national guidelines concerning subclinical hyperthyroidism. There is a need for clear recommendations in guidelines considering diagnostic workup, treatment, and follow-up of subclinical hyperthyroidism. In order to establish this, future research should focus on determining clear and evidence-based intervention thresholds.

Summary: Background: 1H-NMR metabolomics and DNA methylation in blood are widely known biomarkers predicting age-related physiological decline and mortality yet exert mutually independent mortality and frailty signals. Methods: Leveraging multi-omics data in four Dutch population studies (N = 5238, ∼40% of which male) we investigated whether the mortality signal captured by 1H-NMR metabolomics could guide the construction of DNA methylation-based mortality predictors. Findings: We trained DNA methylation-based surrogates for 64 metabolomic analytes and found that analytes marking inflammation, fluid balance, or HDL/VLDL metabolism could be accurately reconstructed using DNA-methylation assays. Interestingly, a previously reported multi-analyte score indicating mortality risk (MetaboHealth) could also be accurately reconstructed. Sixteen of our derived surrogates, including the MetaboHealth surrogate, showed significant associations with mortality, independent of relevant covariates. Interpretation: The addition of our metabolic analyte-derived surrogates to the well-established epigenetic clock GrimAge demonstrates that our surrogates potentially represent valuable mortality signal.

Associations between human genetic variation and clinical phenotypes have become a foundation of biomedical research. Most repositories of these data seek to be disease-agnostic and therefore lack disease-focused views. The Type 2 Diabetes Knowledge Portal (T2DKP) is a public resource of genetic datasets and genomic annotations dedicated to type 2 diabetes (T2D) and related traits. Here, we seek to make the T2DKP more accessible to prospective users and more useful to existing users. First, we evaluate the T2DKP's comprehensiveness by comparing its datasets with those of other repositories. Second, we describe how researchers unfamiliar with human genetic data can begin using and correctly interpreting them via the T2DKP. Third, we describe how existing users can extend their current workflows to use the full suite of tools offered by the T2DKP. We finally discuss the lessons offered by the T2DKP toward the goal of democratizing access to complex disease genetic results.

Understanding recent trends in diabetes is vital for planning future diabetes care. This study updated national trends in the prevalence and incidence of type 2 diabetes (T2D) in the Netherlands from 2004– 2020.Methods: The DIAbetes, MANagement and Treatment (DIAMANT) cohort was used. A cross-sectional design with yearly measurements for the study period was used. The prevalence was calculated by dividing the total number of people with T2D by the total number of all residents. The incidence was calculated by dividing new cases of T2D by the resident population at risk during the calendar year of interest.Results: Among men, the prevalence of T2D in the Netherlands increased from 2.3% in 2004 to 6.3% in 2020. Women’s prevalence increased from 2.3% in 2004 to 5.3% in 2020. During 2005– 2009, the incidence rate for both men and women was relatively stable Between 2010 and 2020, the incidence rate fell about 1.5 per 1000 in both men and women.Conclusion: From 2004– 2020, the prevalence of T2D in the Netherlands more than doubled, with a decreasing incidence from 2010 onwards.Plain Language Summary: Research in contextWhat is already known about this subject?Many studies have reported the increasing prevalence of type 2 diabetes (T2D). However, only a few studies reported the incidence.In a recent systematic review of all these studies, the incidence fell in over a third of the most high-income populations and increased in a minority of populations. Data from the Netherlands were included, but they date back to 1996.Understanding recent trends in diabetes, the prevalence and incidence are vital for planning future diabetes care.What is the key question?To update national trends in the prevalence and incidence of T2D in the Netherlands for 2004-2020.What are the new findings?During 2004-2020, the prevalence of T2D in the Netherlands more than doubled, with a decreasing incidence from 2010 onwards.How might this impact on clinical practice in the foreseeable future?It demonstrates the effectiveness of preventive strategies, public health education and awareness campaigns contributing to this trend.Keywords: type 2 diabetes, prevalence, incidence, epidemiology

Background: : Qualitative research shows barriers in access to healthcare for persons with a migration background, possibly leading to healthcare inequalities. We aimed to compare healthcare use between older community-dwelling persons with a migration background and native Dutch persons with dementia. Methods: : Observational cohort study using electronic health records of NIVEL Primary Care Database (2013–2014) linked to nationwide administrative registries managed by Statistics Netherlands. We included all community-dwelling persons with dementia in the Netherlands aged 65 years and older. Negative binomial and logistic regression analyses were conducted to assess differences in healthcare use outcomes. The largest migrant groups (persons born in Surinam, Turkey and Morocco) were studied separately. Results: : 138,864 persons with dementia were included in the study, whereof 3,991 persons with a migration background and 132,477 native Dutch persons. Moroccan-born persons showed 1.46 higher odds of having an unplanned hospital admission compared to native Dutch persons (95 % Confidence Interval [CI] 1.22–1.74). Persons with a migration background used less professional home care (Odds Ratio [OR] 0.55, 95 %CI 0.51–0.59), and received less home visits from their general practitioner (OR 0.50, 95 %CI 0.43–0.57) than native Dutch persons. Moroccan-born persons had more often an out-of-hours general practitioner consultation compared to native Dutch persons (Incidence Rate Ratio 1.36, 95 %CI 1.18–1.57). Conclusions: : We found significant quantitative differences in healthcare use between persons with a migration background and native Dutch persons with dementia. Further research is needed to gain insight into the reasons of these differences, with consideration of specific migration background.

Background Pelvic organ prolapse is common, causes unpleasant symptoms and negatively affects women’s quality of life. In the UK, most women with pelvic organ prolapse attend clinics for pessary care. Objectives To determine the clinical effectiveness and cost-effectiveness of vaginal pessary self-management on prolapse-specific quality of life for women with prolapse compared with clinic-based care; and to assess intervention acceptability and contextual influences on effectiveness, adherence and fidelity. Design A multicentre, parallel-group, superiority randomised controlled trial with a mixed-methods process evaluation. Participants Women attending UK NHS outpatient pessary services, aged ≥ 18 years, using a pessary of any type/material (except shelf, Gellhorn or Cube) for at least 2 weeks. Exclusions: women with limited manual dexterity, with cognitive deficit (prohibiting consent or self-management), pregnant or non-English-speaking. Intervention The self-management intervention involved a 30-minute teaching appointment, an information leaflet, a 2-week follow-up telephone call and a local clinic telephone helpline number. Clinic-based care involved routine appointments determined by centres’ usual practice. Allocation Remote web-based application; minimisation was by age, pessary user type and centre. Blinding Participants, those delivering the intervention and researchers were not blinded to group allocation. Outcomes The patient-reported primary outcome (measured using the Pelvic Floor Impact Questionnaire-7) was prolapse-specific quality of life, and the cost-effectiveness outcome was incremental cost per quality-adjusted life-year (a specifically developed health Resource Use Questionnaire was used) at 18 months post randomisation. Secondary outcome measures included self-efficacy and complications. Process evaluation data were collected by interview, audio-recording and checklist. Analysis was by intention to treat. Results Three hundred and forty women were randomised (self-management, n = 169; clinic-based care, n = 171). At 18 months post randomisation, 291 questionnaires with valid primary outcome data were available (self-management, n = 139; clinic-based care, n = 152). Baseline economic analysis was based on 264 participants (self-management, n = 125; clinic-based care, n = 139) with valid quality of life and resource use data. Self-management was an acceptable intervention. There was no group difference in prolapse-specific quality of life at 18 months (adjusted mean difference −0.03, 95% confidence interval −9.32 to 9.25). There was fidelity to intervention delivery. Self-management was cost-effective at a willingness-to-pay threshold of £20,000 per quality-adjusted life-year gained, with an estimated incremental net benefit of £564.32 and an 80.81% probability of cost-effectiveness. At 18 months, more pessary complications were reported in the clinic-based care group (adjusted mean difference 3.83, 95% confidence interval 0.81 to 6.86). There was no group difference in general self-efficacy, but self-managing women were more confident in pessary self-management activities. In both groups, contextual factors impacted on adherence and effectiveness. There were no reported serious unexpected serious adverse reactions. There were 32 serious adverse events (self-management, n = 17; clinic-based care, n = 14), all unrelated to the intervention. Skew in the baseline data for the Pelvic Floor Impact Questionnaire-7, the influence of the global COVID-19 pandemic, the potential effects of crossover and the lack of ethnic diversity in the recruited sample were possible limitations. Conclusions Self-management was acceptable and cost-effective, led to fewer complications and did not improve or worsen quality of life for women with prolapse compared with clinic-based care. Future research is needed to develop a quality-of-life measure that is sensitive to the changes women desire from treatment. Study registration This study is registered as ISRCTN62510577. Funding This award was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme (NIHR award ref: 16/82/01) and is published in full in Health Technology Assessment; Vol. 28, No. 23. See the NIHR Funding and Awards website for further award information. Plain language summary Pelvic organ prolapse is a common and distressing condition experienced by large numbers of women. Prolapse is when the organs that are usually in the pelvis drop down into the vagina. Women experience a feeling of something coming down into the vagina, along with bowel, bladder and sexual problems. One possible treatment is a vaginal pessary. The pessary is a device that is inserted into the vagina and holds the pelvic organs back in their usual place. Women who use a vaginal pessary usually come back to clinic every 6 months to have their pessary removed and replaced; this is called clinic-based care. However, it is possible for a woman to look after the pessary herself; this is called self-management. This study compared self-management with clinic-based care. Three hundred and forty women with prolapse took part; 171 received clinic-based care and 169 undertook self-management. Each woman had an equal chance of being in either group. Women in the self-management group received a 30-minute teaching appointment, an information leaflet, a 2-week follow-up telephone call and a telephone number for their local centre. Women in the clinic-based care group returned to clinic as advised by the treating healthcare professional. Self-management was found to be acceptable. Women self-managed their pessary in ways that suited their lifestyle. After 18 months, there was no difference between the groups in women’s quality of life. Women in the self-management group experienced fewer pessary complications than women who received clinic-based care. Self-management costs less to deliver than clinic-based care. In summary, self-management did not improve women’s quality of life more than clinic-based care, but it did lead to women experiencing fewer complications and cost less to deliver in the NHS. The findings support self-management as a treatment pathway for women using a pessary for prolapse. Scientific summary Background Pelvic organ prolapse (hereafter prolapse) is the descent of some, or all, of the female pelvic organs from their usual position in the pelvis into the vagina. Prolapse is a common problem, with studies suggesting that up to 65% of women may be affected. Prolapse incidence increases with age. As the population ages, prolapse presents a growing health problem. Women who experience prolapse report bothersome symptoms that negatively affect their quality of life and body image. Symptoms include a feeling of ‘something coming down’ into the vagina; urinary, bowel and sexual symptoms; and pain. Prolapse can be treated conservatively or surgically. Between 10% and 30% of women who have prolapse surgery may need repeat surgery, and the controversy around the use of surgical mesh has brought the focus onto conservative treatment options. One conservative treatment option is vaginal pessary. The pessary is an inexpensive mechanical device that is inserted into the vagina to support the pelvic organs. Pessaries are widely used in the NHS, with two-thirds of women initially choosing a vaginal pessary to treat their prolapse symptoms. The current UK care pathway for women who use a pessary as treatment for prolapse is that the pessary is usually fitted at a gynaecological clinic, or occasionally at a general practitioner surgery, and the woman returns approximately every 6 months to have it removed and replaced with a new one. However, having to return to clinic every 6 months may be inconvenient for women, having a pessary permanently in situ may interfere with sexual intercourse, and the patient may require a review in clinic before 6 months because the pessary has fallen out or because of pessary complications (e.g. vaginal discomfort). An alternative to clinic-based pessary care is pessary self-management, whereby a woman removes and reinserts the pessary herself at home, thus offering her more control over her ability to maintain and improve her own health. Research in other clinical domains suggests that self-management is beneficial because people improve their self-efficacy (confidence) in looking after their own health. To the best of our knowledge, there is no current evidence on the effectiveness of pessary self-management for women with prolapse. The treatment of prolapse with self-care pessary (TOPSY) study aims to fill that evidence gap. Objective The TOPSY trial aimed to evaluate the clinical effectiveness and cost-effectiveness of self-management of a vaginal pessary on the prolapse-specific quality of life of women with pelvic organ prolapse when compared with clinic-based care. Clinic-based care is the standard operating model for many pessary services across the UK. The process evaluation undertaken concurrently with the trial aimed to assess, using a mixed-methods design, intervention acceptability, pathways to effectiveness, adherence to treatment and fidelity. Methods We undertook a parallel-group, multicentre, randomised controlled trial, with individual randomisation, which assessed the superiority of self-management compared with clinic-based pessary care for women who used a pessary for prolapse. Allocation was carried out remotely via a web-based computer system, with minimisation by age (< 65/≥ 65 years), pessary user type (new user/existing user) and centre. A sample size of 330 women (165 per group) was required to provide 90% power to detect a difference of 20 points in the Pelvic Floor Impact Questionnaire-7 score (which measures prolapse-specific quality of life) at 18 months after randomisation, assuming a standard deviation of 50, two-sided alpha of 0.05 and 20% loss to follow-up. Participants were recruited from 21 UK centres where pessary care was routinely provided. Women who were new pessary users (had used a pessary for ≤ 3 months) and existing users (had used a pessary for > 3 months) were identified by centre staff and via patient notes, clinic lists, caseloads and referral letters. Potentially eligible women were sent an invitation letter or approached in clinic by centre staff. Women were eligible for inclusion if they were aged ≥ 18 years, were using a pessary of any material or type (except shelf, Gellhorn or cube pessaries) and had retained the pessary for at least 2 weeks. Women were excluded if they had limited manual dexterity that would affect their ability to remove and replace their pessary; were judged by their healthcare team to have a cognitive deficit such that it was not possible for them to provide informed consent or to self-manage; were pregnant; or had insufficient understanding of the English language (the self-management intervention was only available in English). The primary outcome of effectiveness was prolapse-specific quality of life, measured using the Pelvic Floor Impact Questionnaire-7, and of cost-effectiveness was incremental cost per quality-adjusted life-year at 18 months post randomisation. Interim follow-ups were undertaken at 6 and 12 months. Secondary outcome measures included generic quality of life [measured using the EuroQol-5 Dimensions, five-level (EQ-5D-5L)]; pelvic floor symptoms (measured using the Pelvic Floor Distress Inventory-20); sexual function (measured using the prolapse/incontinence sexual questionnaire-IUGA-Revised); self-efficacy (measured using the General Self-efficacy Scale); pessary complications; pessary use; and pessary confidence. Resource use data were collected using a specifically developed health Resource Use Questionnaire. Study centres received a training visit during which the principles of self-management were explained and the intervention delivery staff were trained in the components of the intervention. Each centre also received a training manual that provided written guidance on the intervention. Women randomised to self-management received: a 30-minute self-management teaching appointment where they were taught to, and given the opportunity to try to, remove, clean and reinsert their own pessary a self-management information leaflet that provided written and diagrammatic information on pessary self-management a 2-week follow-up telephone call to assess if they had been able to remove, clean and reinsert their pessary since the teaching appointment and to assess any difficulties they experienced a telephone helpline number for their local clinical centre. Women in the clinic-based care group received routine appointments at which their pessary was removed and cleaned, or changed for a new one, and replaced by a healthcare professional. The interval between the appointments was determined by the usual practice of the centre. A concurrent mixed-methods process evaluation was undertaken to assess intervention acceptability, pathways to effectiveness, adherence to treatment and fidelity. Recruiting staff at centres were asked to audio-record a sample of their recruitment discussions. Staff delivering the intervention were asked to record a sample of self-management teaching appointments and 2-week follow-up telephone calls and to complete a checklist for every self-management teaching session undertaken to allow assessment of fidelity to the intervention. A subsample of women who were randomised in the trial and consented to take part in an additional interview study were interviewed at baseline and 18 months. Eligible women who declined to be randomised but were willing to take part in an interview study were also interviewed at baseline and 18 months. The Pessary Use Questionnaire included an open question about women’s experiences of their trial group. The interviews and open questions aimed to assess acceptability, adherence and pathways to effectiveness. Finally, recruiting centre staff and healthcare professionals who delivered the intervention were invited to take part in an interview to increase understanding of pathways to effectiveness and fidelity. A within-trial economic evaluation was conducted to compare the costs and benefits, measured in quality-adjusted life-years, of self-management with clinic-based care over the 18 months post randomisation. In addition, a decision-analytic model was developed using the trial data to extend the analysis over a 5-year period. Healthcare resource use data were collected from the clinic visit and telephone support case report forms and from the participant-completed Resource Use Questionnaire. Costs were attached to resource use from published sources. Health state utility values were elicited from responses to the EQ-5D-5L to estimate the difference in quality-adjusted life-years between the trial groups. The trial analysis followed the intention to treat principle, and the analyses of all study elements were documented in prespecified analysis plans. The qualitative analysis for the process evaluation followed framework analysis methods and, where appropriate, case study analytic methods. Results Key results: trial Three hundred and forty women were randomised: 169 to the self-management group and 171 to the clinic-based care group. At 18 months post randomisation, 291 questionnaires with valid primary outcome data were available: 139 (82.2%) in the self-management group and 152 (88.9%) in the clinic-based care group. There was no evidence of a difference between the groups in prolapse-specific quality of life (measured using the Pelvic Floor Impact Questionnaire-7) at 18 months (adjusted mean difference −0.03, 95% confidence interval −9.32 to 9.25). Sensitivity analysis of the primary outcome showed no significant difference between the groups under a range of different assumptions and prespecified sensitivity analyses. A subgroup analysis of the primary outcome showed no significant effect of trial group by subgroup interactions (subgroups were age < 65 vs. ≥ 65 years, new vs. existing pessary user and hysterectomy vs. no hysterectomy at baseline). At the 18-month follow-up, a greater proportion of pessary complications were reported in the clinic-based care group than in the self-management group (adjusted mean difference 3.83, 95% confidence interval 0.81 to 6.86). There was no difference between the groups in general self-efficacy, but women in the self-management group were more confident in their ability to manage pessary-related problems and to insert and remove their pessary. An analysis adjusting for clinic-based care appointments cancelled due to the COVID-19 pandemic did not alter the findings. Key results: process evaluation Self-management was reported to be an acceptable intervention to women and to healthcare professionals. Women (whether they received self-management or not) and healthcare professionals reported benefits from pessary self-management to women and the NHS and valued the possibilities provided to women who could self-manage their pessary, such as flexibility and independence in using the pessary as needed. There was fidelity to self-management intervention delivery and there was minimal variance in the delivery of clinic-based care across the study centres. Self-management delivery can be integrated within existing service structures. Interview data demonstrated that women’s adherence to their allocated group ranged from not adherent at all to completely adherent in all aspects, and this was the case in both groups. The COVID-19 pandemic did have an impact on adherence, especially among those in the clinic-based care group when clinic appointments were suspended, which led some women to remove their own pessary. Although the pandemic might have had some effect on adherence, multiple other contextual factors influenced adherence, such as good general health, which influenced it in both groups. Multiple contextual factors impacted on pathways to effectiveness for both trial groups. There was variance in women’s quality of life in both groups across the 18 months’ follow-up. The pessary itself influenced women’s quality of life, regardless of trial group. There was at least the potential for self-management to further enhance that quality of life over and above the influence of the pessary itself. Women in the self-management group had different self-efficacy from those in the clinic-based group. Women in the self-management group felt more confident in addressing common problems with their pessary, such as discharge or slippage, on their own without the need for additional clinic appointments. Key results: economic evaluation The within-trial economic analysis indicated that clinic-based care was dominated by self-management. There was no significant difference in the mean number of quality-adjusted life-years gained between self-management and clinic-based care (0.021), but the mean cost was lower for self-management than for clinic-based care (£578 vs. £728). The incremental net benefit estimated at a willingness-to-pay threshold of £20,000 per quality-adjusted life-year gained was £564, with an 80.8% probability of cost-effectiveness. The modelling results are consistent with the trial analysis. The incremental net benefit at 5 years was estimated as £4221 and the probability that self-management is a cost-effective intervention was estimated as 69.7%. Key results: synthesis There was no evidence that self-management improved prolapse-specific or general quality of life more than clinic-based care. Although qualitative findings suggested that quality of life had the potential to be improved more in the self-management group, this did not translate beyond participant-level data. The proposed mechanism of action for the intervention was self-efficacy. General self-efficacy did not differ between the groups at 18 months. Women who self-managed were more confident in their abilities to insert and remove their pessary and to manage problems experienced with their pessary than women in the clinic-based care group. There was fidelity to the self-management and clinic-based care intervention delivery, with the groups receiving different interventions, confirming that the trial was a true test. There was variance in adherence to trial group by the women; approximately 40% of the clinic-based care group removed the pessary themselves at least once at some point during follow-up, and 34 women in the self-management group crossed over to clinic-based care. Women in the self-management group reported fewer complications than women in the clinic-based care group. Experience of complications led to a greater likelihood of women discontinuing pessary use. Conclusions Implications for health care Healthcare professionals and policy-makers can be confident that in offering self-management as an option to women who use a vaginal pessary to manage pelvic organ prolapse they are offering an acceptable intervention that will not make women’s quality of life better or worse than clinic-based care. Self-management will, however, reduce the pessary-related complications that women experience and will cost the NHS less to deliver than standard clinic-based care models. Self-management of vaginal pessaries should be offered as part of NHS services from the outset of pessary care and as part of routine, ongoing care. In offering self-management to women, healthcare professionals should explain the lower complication rates experienced by women who self-manage and the possible mechanisms that may lead to that reduction (such as women’s confidence in removing the pessary when experiencing discomfort). Healthcare professionals who deliver self-management training may wish to add further information about options for pessary removal into that training, as women found pessary removal more difficult than pessary insertion. Recommendations for research (in priority order) Future research is needed to identify constructs that are important to women in measuring their prolapse-specific quality of life. This may necessitate the generation of a new measure that has greater sensitivity to quality-of-life constructs beyond the symptomatic changes linked to the pessary itself. Future trials of self-management should test the effectiveness of self-management with a wide range of ethnic groups and with women of different abilities to assess its effectiveness in these populations. This may include the testing of devices that support pessary removal or insertion. Future research is needed that focuses on self-management follow-up. For example, can follow-up be women-initiated, or does it need to be planned at specific intervals? Future research on pessary self-management is needed to look at possible links between pessary continuation and complications, including which specific complications are more likely to lead to discontinuation.

Computer Science - Cryptography and Security - Abstract
Today, we use smartphones as multi-purpose devices that communicate with their environment to implement context-aware services, including asset tracking, indoor localization, contact tracing, or access control. As a de-facto standard, Bluetooth is available in virtually every smartphone to provide short-range wireless communication. Importantly, many Bluetooth-driven applications such as Phone as a Key (PaaK) for vehicles and buildings require proximity of legitimate devices, which must be protected against unauthorized access. In earlier access control systems, attackers were able to violate proximity-verification through relay station attacks. However, the vulnerability of Bluetooth against such attacks was yet unclear as existing relay attack strategies are not applicable or can be defeated through wireless distance measurement. In this paper, we design and implement an analog physical-layer relay attack based on low-cost off-the-shelf radio hardware to simultaneously increase the wireless communication range and manipulate distance measurements. Using our setup, we successfully demonstrate relay attacks against Bluetooth-based access control of a car and a smart lock. Further, we show that our attack can arbitrarily manipulate Multi-Carrier Phase-based Ranging (MCPR) while relaying signals over 90 m., Comment: Accepted for presentation at WiSec '22

AbstractObjective To assess the cultural competence (CC) of GP trainees and GP trainers.Design and setting: A cross-sectional survey study was conducted at the GP Training Institute of Amsterdam UMC.Subjects We included 92 GP trainees and 186 GP trainers.Main outcome measures We measured the three domains of cultural competency: 1) knowledge, 2) culturally competent attitudes and 3) culturally competent skills. Regression models were used to identify factors associated with levels of CC. Participants rated their self-perceived CC at the beginning and end of the survey, and the correlation between self-perceived and measured CC was assessed.Results Approximately 94% of the GP trainees and 81% of the GP trainers scored low on knowledge; 45% and 42%, respectively, scored low on culturally competent attitudes. The level of culturally competent skills was moderate (54.3%) or low (48.4%) for most GP trainees and GP trainers. The year of residency and the GP training institute were significantly associated with one or more (sub-)domains of CC in GP trainees. Having >10% migrant patients and experience as a GP trainer were positively associated with one or more (sub-) domains of cultural competence in GP trainers. The correlation between measured and self-perceived CC was positive overall but very weak (Spearman correlation coefficient ranging from −0.1–0.3).Conclusion The level of cultural competence was low in both groups, especially in the knowledge scores. Cultural competence increased with experience and exposure to an ethnically diverse patient population. Our study highlights the need for cultural competence training in the GP training curricula.

The COVID-19 pandemic has had a significant impact on healthcare systems worldwide, including the postponing or canceling of appointments and procedures for type 2 diabetes (T2D) care by general practitioners (GPs) in the Netherlands. The aim of this study was to investigate the impact of the COVID-19 pandemic on primary healthcare use and clinical measurements for people with T2D. Additionally, we aimed to determine if changes were observed among specific risk groups: (1) persons 70 years or older, or below 70 years, (2) patients who were meeting their HbA1c targets and those who were not, and (3) patients with high-risk and non-high-risk T2D. This retrospective cohort study among persons with T2D was conducted using data from the DIAbetes MANagement and Treatment (DIAMANT) data infrastructure, deriving data from electronic medical records of Dutch GPs. The study assessed GP visit counts, and counts and values of clinical measurements, including hemoglobin A1c (HbA1c), body mass index (BMI), low-density lipoprotein (LDL) cholesterol, and systolic blood pressure (SBP). Adjusted negative binomial (NB) regression and generalized estimating equations (GEE) models were used to estimate GP visit counts and population averages of clinical measurements, respectively, comparing 2019 (pre-pandemic) with 2020 (during the pandemic). Changes in specific groups were examined by stratifying outcomes for the aforementioned subgroups. The cohort consisted of 182,048 patients with T2D (47% female, mean age 69 ± 13 years) on 1 March 2019, of which 168,097 persons (92%) still contributed follow-up data in 2020. We observed an increase in total GP visits in 2020, with an adjusted rate ratio (RR) of 1.09 (95% CI 1.08–1.09). The frequency increased for office visits (RR 1.06; 1.06–1.07) and phone calls (RR 1.33; 1.31–1.35) but remained stable for home visits (RR 1.02; 0.99–1.04). On both population and individual levels, HbA1c values increased in 2020 by 1.65 (1.59–1.70) mmol/mol compared to 2019. Observed changes in 2020 for BMI, LDL, and SBP values were also statistically significant but small. Subgroup stratifications showed higher scores of all clinical measurements in younger persons (

Refractories are characterized by their ability to withstand high temperatures that reach 2800°C, their ability to withstand sudden changes in temperature, resist mechanical shocks, due to the formation of glass at a temperature of 1050-1100°C, it is required that the molds manufactured from refractories withstand that temperature. This is in addition to the ability of the refractory material to show the fine details and the prominent and recessed sculptural surfaces (smooth - rough) in the glass product, and to achieve the uniqueness and excellence of the glass product.This is due to the requirements of refractory mold in its manufacture and assortment with manual blowing in terms of its ability to withstand pressures, non-fragmentation, thermal endurance that reaches (1500 - 1750°C), and a low rate of expansion and contraction that reaches ± 0.05 mm, as well as its flat smoothness, which is considered as a mirror of a model formation.Since the glass material is acidic, it requires that the components of the refractory composition of the mold be acidic or neutral as well. To prevent the adhesion with the glass components thus, some refractories were selected that enter into the work of refractory formulations that can achieve chemical and natural properties suitable in the manufacture of glass forming molds by manual blowing. (16) Refractory compositions were made, and the research reached to find new refractories that meet the requirements. Thus, it is recommended to use refractories for producing the prototype of the glass products which are characterized by aesthetic products.

Computer Science - Information Theory - Abstract
Physical layer key generation (PKG) is a promising means to provide on-the-fly shared secret keys by exploiting the intrinsic randomness of the radio channel. However, the performance of PKG is highly dependent on the propagation environments. Due to its feature of controlling the wireless environment, reconfigurable intelligent surface~(RIS) is appealing to be applied in PKG. In this paper, in contrast to the existing literature, we investigate both the constructive and destructive effects of RIS on the PKG scheme. For the constructive aspect, we have identified static and wave-blockage environments as two RIS-empowered-PKG applications in future wireless systems. In particular, our experimental results in a static environment showed that RIS can enhance the entropy of the secret key, achieving a key generation rate (KGR) of 97.39 bit/s with a bit disagreement rate (BDR) of 0.083. In multi-user systems where some remote users are in worse channel conditions, the proposed RIS-assisted PKG algorithm improves the sum secret key rate by more than 2 dB, compared to the literature. Furthermore, we point out that RIS could be utilized by an attacker to perform new jamming and leakage attacks and give countermeasures, respectively. Finally, we outline future research directions for PKG systems in light of the RIS., Comment: 7 pages, 5 figures
