Effectiveness of interventions for improving physical activity level in working-age people (aged 18-60 years) with type 2 diabetes: a systematic review and meta-analysis.

BACKGROUND: The increasing prevalence of type 2 diabetes in working-age people imposes a substantial societal burden. Although physical activity is crucial for diabetes management, limited evidence exists to inform optimal strategies for promoting physical activity in this population. We aimed to determine and compare the effectiveness of interventions for increasing physical activity level in working-age people with diabetes. METHODS: In this systematic review and meta-analysis, we searched Web of Science, the Cochrane Library, Medline, Embase, PsycINFO, ClinicalTrials.gov, and ICTRP for papers published between Jan 1, 1931, and June 30, 2022, in English. Search terms included "physical activity", "diabetes", and "randomised controlled trial". We included trials reporting the effects of interventions on physical activity level (objectively or subjectively measured) in people with type 2 diabetes aged 18-60 years. Two independent reviewers conducted summary data extraction and quality assessment. We used pairwise random-effects, frequentist network meta-analyses, and meta-regression to obtain pooled effects. Heterogeneity was evaluated using I2 statistic. The risk of bias and certainty of evidence were assessed using the Cochrane risk-of-bias 2 tool and the Grading of Recommendations Assessment, Development, and Evaluation. This study is registered with PROSPERO (CRD42022323165). FINDINGS: We identified 52 trials (6257 participants) from 21 countries (32 Asia, ten North America, eight Europe, one Australia, one Africa). The overall risk of bias was classified as "some concerns" for included studies. Four types of interventions (structured exercise training, physical activity education, psychological intervention, physical activity education plus psychological intervention) were identified. Compared with control groups, the interventions showed significant effects in objectively measured (standardised mean difference 0·77, 95% CI 0·27-1·27, low certainty), subjectively measured (0·88, 0·40-1·35, very low certainty), and overall physical activity (0·82, 0·48-1·16, moderate certainty). Physical activity education exerted large effect in overall physical activity compared with control groups. Psychological intervention exerted large effects in overall physical activity compared with other interventions. Heterogeneity was high (I2=96-97%). Intervention setting (p=0·04) and facilitator (p=0·03) showed effects on heterogeneity. INTERPRETATION: Psychologically modelled education might be the most beneficial way of promoting physical activity. Intervention setting and facilitator type should be considered when designing interventions for improving physical activity level in working-age people with type 2 diabetes. Limitations of this review include restriction to the English language and considerable heterogeneity between studies. FUNDING: King's-China Scholarship Council PhD Scholarship (202108440151).

Exploring the determinants of oral health care uptake among women with gestational diabetes mellitus: A qualitative study to develop a logic model and framework for an oral health intervention.

INTRODUCTION: Gestational diabetes mellitus (GDM) is a condition of glucose intolerance in pregnancy. Oral health has been shown to mediate blood glucose management and pregnancy outcomes. There is also a greater prevalence of poor oral health in GDM pregnancies when compared to normoglycemic pregnancies. While current guidelines recommend an oral health review as part of diabetes and pregnancy management, it is under-considered in GDM care. Hence, it is important to understand how to improve oral health care in this context. AIM: To explore the determinants of oral health care uptake among women with GDM to develop a logic model for an intervention to improve awareness and activation of oral health behaviours in this population. METHODS: Semi-structured interviews were used to collect the data and the Theoretical Domains Framework inspired the interview guide. The study population consisted of UK-based women with GDM over 18 years of age. The data were analysed with Framework Analysis and the COM-B Model was used to orientate the data. RESULTS: Seventeen women participated in the study. Five themes including knowledge about oral health; the health of the baby; the impact of the GDM diagnosis; social support and barriers and facilitators were found to influence the uptake of oral health care. CONCLUSIONS: This study developed an evidence-based logic model of the determinants of oral health care uptake among women with GDM. This will serve as a framework for developing an oral health intervention. This study may be the starting point for initiating conversations about implementing oral health care in GDM management.

Standardising personalised diabetes care across European health settings: A person-centred outcome set agreed in a multinational Delphi study.

OBJECTIVE: Standardised person-reported outcomes (PRO) data can contextualise clinical outcomes enabling precision diabetes monitoring and care. Comprehensive outcome sets can guide this process, but their implementation in routine diabetes care has remained challenging and unsuccessful at international level. We aimed to address this by developing a person-centred outcome set for Type 1 and Type 2 diabetes, using a methodology with prospects for increased implementability and sustainability in international health settings. METHODS: We used a three-round questionnaire-based Delphi study to reach consensus on the outcome set. We invited key stakeholders from 19 countries via purposive snowball sampling, namely people with diabetes (N = 94), healthcare professionals (N = 65), industry (N = 22) and health authorities (N = 3), to vote on the relevance and measurement frequency of 64 previously identified clinical and person-reported outcomes. Subsequent consensus meetings concluded the study. RESULTS: The list of preliminary outcomes was shortlisted via the consensus process to 46 outcomes (27 clinical outcomes and 19 PROs). Two main collection times were recommended: (1) linked to a medical visit (e.g. diabetes-specific well-being, symptoms and psychological health) and (2) annually (e.g. clinical data, general well-being and diabetes self management-related outcomes). CONCLUSIONS: PROs are often considered in a non-standardised way in routine diabetes care. We propose a person-centred outcome set for diabetes, specifically considering psychosocial and behavioural aspects, which was agreed by four international key stakeholder groups. It guides standardised collection of meaningful outcomes at scale, supporting individual and population level healthcare decision making. It will be implemented and tested in Europe as part of the H2O project.

A qualitative study exploring partner involvement in the management of gestational diabetes mellitus: The experiences of women and partners.

AIMS: The aims of the study were to explore the experiences of women with gestational diabetes mellitus (GDM) and their partners and examine the factors influencing partner involvement in GDM management, seeking to inform a targeted couple-based intervention. DESIGN: A descriptive qualitative study. METHODS: We conducted semi-structured interviews with 14 women with GDM and their partners. Participants were recruited through convenience sampling from a tertiary hospital in Xi'an, China. Data were analysed using thematic analysis. RESULTS: Three themes and 12 subthemes were identified. Theme I: Women's expectations of their partner's involvement in GDM management-practical support and emotional support. Theme II: Partner involvement in GDM management-constructive involvement, unhelpful involvement with good intentions and insufficient involvement. Theme III: Factors that influence partner involvement in GDM-knowledge of GDM, GDM risk perception, health consciousness, attitudes towards the treatment plan, couple communication regarding GDM management, family roles and appraisal of GDM management responsibility. CONCLUSION: Women desired practical and emotional support from partners. The types of partner involvement in GDM management varied. Some partners provided constructive support, while some partners' involvement was limited, non-existent or actively unhelpful. By combining these results with the factors influencing partner involvement, our findings may help healthcare professionals develop strategies to involve partners in GDM care and enhance women's ability to manage GDM. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: Partner involvement in GDM care may help them understand and better attend to women's needs, thus improving their experience and potential outcomes. This study highlights novel factors that need to be considered in developing couple-based interventions for this population. REPORTING METHOD: The reporting follows the COREQ checklist. PATIENT OR PUBLIC CONTRIBUTION: Some patients were involved in data interpretation. There is no public contribution.

Prevalence and associated factors of sexual dysfunction in premenopausal women with type 1 diabetes: A systematic review and meta-analysis.

BACKGROUND: Sexual dysfunction (SD) in women with diabetes is a multifaceted complication driven by hormonal, neuropathic and psychosocial factors. It has been reported that the prevalence of SD is higher in women with type 1 diabetes compared to both women with type 2 diabetes and women without diabetes. However, prevalence estimates of SD in women with type 1 diabetes are variable, due to the heterogeneity of the conducted studies and the various confounding factors that are associated with SD. AIM: This review aimed to estimate the prevalence of SD in premenopausal women with type 1 diabetes compared to women without diabetes; consider current methods for measuring SD; and identify factors associated with SD in women with type 1 diabetes. METHOD: A systematic review of the literature was conducted. Four electronic databases (Embase, MEDLINE, CINAHL, PsycINFO) were searched between 15 March and 29 April 2022, the search was updated on 4 February 2023 to identify studies that assessed SD in women with type 1 diabetes. FINDINGS: The search yielded in 1104 articles; of these, 180 were assessed for eligibility. A meta-analysis of eight eligible studies revealed that the odds of experiencing SD is three times higher in women with type 1 diabetes compared to women without diabetes (OR = 3.8 95%CI 1.8-8.0, p < 0.001). The most commonly used measure of SD was the female sexual function index (FSFI); in three studies, this was combined with the female sexual distress scale (FSDS). Factors that have shown significant association with SD are depression, anxiety and duration of diabetes. CONCLUSION: This review has shown that SD is a significant issue for women with type 1 diabetes. These findings should encourage diabetes professionals and policymakers to give more attention to female SD (FSD) by incorporating it into care pathways and clinical guidelines.

'No one ever asks about something that actually is relevant to my life': A qualitative study of diabetes and diabetes care experiences of young women with type 2 diabetes during their reproductive years.

AIM: To understand the health needs, experiences, and views of women with type 2 diabetes in relation to diabetes, reproductive health experiences, and general wellbeing. METHOD: A qualitative study using semi-structured interviews. Thirty-six women with type 2 diabetes (median age 37 years; age ranges 20-45 years; median diabetes duration 4.5 years), recruited through social media and charities in the UK (n = 23) and Turkey (n = 13). Video interviews (n = 28) were audio recorded and transcribed verbatim. Email interviews (n = 8) and transcribed video interviews were analysed using Framework Analysis. RESULTS: Two overarching themes were identified: (1) Perception of self and identity, (2) type 2 diabetes care is not orientated to women's needs. These themes highlight that living with type 2 diabetes was negatively perceived by the women in terms of their self-identity and reproductive health. Women reported that the diabetes care provided was often not appropriate or relevant to their health needs, and neglected issues of relevance to them. The women voiced ideas for enhancing current care to reflect their health needs, in particular the need for more emotional and peer-based support. CONCLUSION: Living with type 2 diabetes may negatively impact how women view themselves and how they relate to the roles they identify with such as, as a partner, mother, colleague. Current healthcare systems are not orientated to the specific needs of younger women with type 2 diabetes with limited opportunities to target their diabetes care around their health and wellbeing concerns and interests.

Interventions to enhance pre-pregnancy care for women with type 2 diabetes: A systematic review of the literature.

AIMS: The aim of the study was to examine the content and impact of interventions that have been used to increase the uptake of pre-pregnancy care for women with type 2 diabetes, and their impact on maternal and fetal outcomes. METHODS: A systematic search of multiple databases was conducted in November 2021, and updated July 2022, to identify studies assessing interventions to enhance pre-pregnancy care for women with type 2 diabetes. Over 10% of articles were screened by two reviewers at title and abstract phase, after which all selected full-text articles were screened by two reviewers. Quality assessment was conducted using the Critical Appraisal Skills Programme checklist for cohort studies. Meta-analysis was not possible due to study heterogeneity; therefore, narrative synthesis was conducted. RESULTS: Four eligible cohort studies were identified. The conclusions able to be drawn by this review were limited as women with type 2 diabetes (n = 800) were in the minority in all four studies (35%-40%) and none of the interventions were exclusively tailored for them. The uptake of pre-pregnancy care was lower in women with type 2 diabetes (8%-10%) compared with other participant groups in the studies. Pregnancy preparation indicators generally improved among all groups exposed to pre-pregnancy care, with varying impact on pregnancy outcomes. CONCLUSIONS: This review demonstrates that previous interventions have had a limited impact on pre-pregnancy care uptake in women with type 2 diabetes. Future studies should focus on tailored interventions for improving pre-pregnancy care for women with type 2 diabetes, particularly those from ethnic minorities and living in poorer communities.

Essential steps in primary care management of older people with Type 2 diabetes: an executive summary on behalf of the European geriatric medicine society (EuGMS) and the European diabetes working party for older people (EDWPOP) collaboration.

We present an executive summary of a guideline for management of type 2 diabetes mellitus in primary care written by the European Geriatric Medicine Society, the European Diabetes Working Party for Older People with contributions from primary care practitioners and participation of a patient's advocate. This consensus document relies where possible on evidence-based recommendations and expert opinions in the fields where evidences are lacking. The full text includes 4 parts: a general strategy based on comprehensive assessment to enhance quality and individualised care plan, treatments decision guidance, management of complications, and care in case of special conditions. Screening for frailty and cognitive impairment is recommended as well as a comprehensive assessment all health conditions are concerned, including end of life situations.

Monte Carlo Physarum Machine: Characteristics of Pattern Formation in Continuous Stochastic Transport Networks.

We present Monte Carlo Physarum Machine (MCPM): a computational model suitable for reconstructing continuous transport networks from sparse 2D and 3D data. MCPM is a probabilistic generalization of Jones's (2010) agent-based model for simulating the growth of Physarum polycephalum (slime mold). We compare MCPM to Jones's work on theoretical grounds, and describe a task-specific variant designed for reconstructing the large-scale distribution of gas and dark matter in the Universe known as the cosmic web. To analyze the new model, we first explore MCPM's self-patterning behavior, showing a wide range of continuous network-like morphologies-called polyphorms-that the model produces from geometrically intuitive parameters. Applying MCPM to both simulated and observational cosmological data sets, we then evaluate its ability to produce consistent 3D density maps of the cosmic web. Finally, we examine other possible tasks where MCPM could be useful, along with several examples of fitting to domain-specific data as proofs of concept.

The impact of the COVID-19 pandemic on people with diabetes and diabetes services: A pan-European survey of diabetes specialist nurses undertaken by the Foundation of European Nurses in Diabetes survey consortium.

AIM: To describe diabetes nurses' perspectives on the impact of the COVID-19 pandemic on people with diabetes and diabetes services across Europe. METHODS: An online survey developed using a rapid Delphi method. The survey was translated into 17 different languages and disseminated electronically in 27 countries via national diabetes nurse networks. RESULTS: Survey responses from 1829 diabetes nurses were included in the analysis. The responses indicated that 28% (n = 504) and 48% (n = 873) of diabetes nurses felt the COVID-19 pandemic had impacted 'a lot' on the physical and psychological risks of people with diabetes, respectively. The following clinical problems were identified as having increased 'a lot': anxiety 82% (n = 1486); diabetes distress 65% (n = 1189); depression 49% (n = 893); acute hyperglycaemia 39% (n = 710) and foot complications 18% (n = 323). Forty-seven percent (n = 771) of respondents identified that the level of care provided to people with diabetes had declined either extremely or quite severely. Self-management support, diabetes education and psychological support were rated by diabetes nurse respondents as having declined extremely or quite severely during the COVID-19 pandemic by 31% (n = 499), 63% (n = 1,027) and 34% (n = 551), respectively. CONCLUSION: The findings show that diabetes nurses across Europe have seen significant increases in both physical and psychological problems in their patient populations during COVID-19. The data also show that clinical diabetes services have been significantly disrupted. As the COVID-19 situation continues, we need to adapt care systems with some urgency to minimise the impact of the pandemic on the diabetes population.

Telephone interventions for symptom management in adults with cancer.

BACKGROUND: People with cancer experience a variety of symptoms as a result of their disease and the therapies involved in its management. Inadequate symptom management has implications for patient outcomes including functioning, psychological well-being, and quality of life (QoL). Attempts to reduce the incidence and severity of cancer symptoms have involved the development and testing of psycho-educational interventions to enhance patients' symptom self-management. With the trend for care to be provided nearer patients' homes, telephone-delivered psycho-educational interventions have evolved to provide support for the management of a range of cancer symptoms. Early indications suggest that these can reduce symptom severity and distress through enhanced symptom self-management. OBJECTIVES: To assess the effectiveness of telephone-delivered interventions for reducing symptoms associated with cancer and its treatment. To determine which symptoms are most responsive to telephone interventions. To determine whether certain configurations (e.g. with/without additional support such as face-to-face, printed or electronic resources) and duration/frequency of intervention calls mediate observed cancer symptom outcome effects. SEARCH METHODS: We searched the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 1); MEDLINE via OVID (1946 to January 2019); Embase via OVID (1980 to January 2019); (CINAHL) via Athens (1982 to January 2019); British Nursing Index (1984 to January 2019); and PsycINFO (1989 to January 2019). We searched conference proceedings to identify published abstracts, as well as SIGLE and trial registers for unpublished studies. We searched the reference lists of all included articles for additional relevant studies. Finally, we handsearched the following journals: Cancer, Journal of Clinical Oncology, Psycho-oncology, Cancer Practice, Cancer Nursing, Oncology Nursing Forum, Journal of Pain and Symptom Management, and Palliative Medicine. We restricted our search to publications published in English. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs that compared one or more telephone interventions with one other, or with other types of interventions (e.g. a face-to-face intervention) and/or usual care, with the stated aim of addressing any physical or psychological symptoms of cancer and its treatment, which recruited adults (over 18 years) with a clinical diagnosis of cancer, regardless of tumour type, stage of cancer, type of treatment, and time of recruitment (e.g. before, during, or after treatment). DATA COLLECTION AND ANALYSIS: We used Cochrane methods for trial selection, data extraction and analysis. When possible, anxiety, depressive symptoms, fatigue, emotional distress, pain, uncertainty, sexually-related and lung cancer symptoms as well as secondary outcomes are reported as standardised mean differences (SMDs) with 95% confidence intervals (CIs), and we presented a descriptive synthesis of study findings. We reported on findings according to symptoms addressed and intervention types (e.g. telephone only, telephone combined with other elements). As many studies included small samples, and because baseline scores for study outcomes often varied for intervention and control groups, we used change scores and associated standard deviations. The certainty of the evidence for each outcome was interpreted using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS: Thirty-two studies were eligible for inclusion; most had moderate risk of bias,often related to blinding. Collectively, researchers recruited 6250 people and studied interventions in people with a variety of cancer types and across the disease trajectory, although many participants had breast cancer or early-stage cancer and/or were starting treatment. Studies measured symptoms of anxiety, depression, emotional distress, uncertainty, fatigue, and pain, as well as sexually-related symptoms and general symptom intensity and/or distress. Interventions were primarily delivered by nurses (n = 24), most of whom (n = 16) had a background in oncology, research, or psychiatry. Ten interventions were delivered solely by telephone; the rest combined telephone with additional elements (i.e. face-to-face consultations and digital/online/printed resources). The number of calls delivered ranged from 1 to 18; most interventions provided three or four calls. Twenty-one studies provided evidence on effectiveness of telephone-delivered interventions and the majority appeared to reduce symptoms of depression compared to control. Nine studies contributed quantitative change scores (CSs) and associated standard deviation results (or these could be calculated). Likewise, many telephone interventions appeared effective when compared to control in reducing anxiety (16 studies; 5 contributed quantitative CS results); fatigue (9 studies; 6 contributed to quantitative CS results); and emotional distress (7 studies; 5 contributed quantitative CS results). Due to significant clinical heterogeneity with regards to interventions introduced, study participants recruited, and outcomes measured, meta-analysis was not conducted. For other symptoms (uncertainty, pain, sexually-related symptoms, dyspnoea, and general symptom experience), evidence was limited; similarly meta-analysis was not possible, and results from individual studies were largely conflicting, making conclusions about their management through telephone-delivered interventions difficult to draw. Heterogeneity was considerable across all trials for all outcomes. Overall, the certainty of evidence was very low for all outcomes in the review. Outcomes were all downgraded due to concerns about overall risk of bias profiles being frequently unclear, uncertainty in effect estimates and due to some inconsistencies in results and general heterogeneity. Unsubstantiated evidence suggests that telephone interventions in some capacity may have a place in symptom management for adults with cancer. However, in the absence of reliable and homogeneous evidence, caution is needed in interpreting the narrative synthesis. Further, there were no clear patterns across studies regarding which forms of interventions (telephone alone versus augmented with other elements) are most effective. It is impossible to conclude with any certainty which forms of telephone intervention are most effective in managing the range of cancer-related symptoms that people with cancer experience. AUTHORS' CONCLUSIONS: Telephone interventions provide a convenient way of supporting self-management of cancer-related symptoms for adults with cancer. These interventions are becoming more important with the shift of care closer to patients' homes, the need for resource/cost containment, and the potential for voluntary sector providers to deliver healthcare interventions. Some evidence supports the use of telephone-delivered interventions for symptom management for adults with cancer; most evidence relates to four commonly experienced symptoms - depression, anxiety, emotional distress, and fatigue. Some telephone-delivered interventions were augmented by combining them with face-to-face meetings and provision of printed or digital materials. Review authors were unable to determine whether telephone alone or in combination with other elements provides optimal reduction in symptoms; it appears most likely that this will vary by symptom. It is noteworthy that, despite the potential for telephone interventions to deliver cost savings, none of the studies reviewed included any form of health economic evaluation. Further robust and adequately reported trials are needed across all cancer-related symptoms, as the certainty of evidence generated in studies within this review was very low, and reporting was of variable quality. Researchers must strive to reduce variability between studies in the future. Studies in this review are characterised by clinical and methodological diversity; the level of this diversity hindered comparison across studies. At the very least, efforts should be made to standardise outcome measures. Finally, studies were compromised by inclusion of small samples, inadequate concealment of group allocation, lack of observer blinding, and short length of follow-up. Consequently, conclusions related to symptoms most amenable to management by telephone-delivered interventions are tentative.

The Kappa platform for rule-based modeling.

Motivation: We present an overview of the Kappa platform, an integrated suite of analysis and visualization techniques for building and interactively exploring rule-based models. The main components of the platform are the Kappa Simulator, the Kappa Static Analyzer and the Kappa Story Extractor. In addition to these components, we describe the Kappa User Interface, which includes a range of interactive visualization tools for rule-based models needed to make sense of the complexity of biological systems. We argue that, in this approach, modeling is akin to programming and can likewise benefit from an integrated development environment. Our platform is a step in this direction. Results: We discuss details about the computation and rendering of static, dynamic, and causal views of a model, which include the contact map (CM), snaphots at different resolutions, the dynamic influence network (DIN) and causal compression. We provide use cases illustrating how these concepts generate insight. Specifically, we show how the CM and snapshots provide information about systems capable of polymerization, such as Wnt signaling. A well-understood model of the KaiABC oscillator, translated into Kappa from the literature, is deployed to demonstrate the DIN and its use in understanding systems dynamics. Finally, we discuss how pathways might be discovered or recovered from a rule-based model by means of causal compression, as exemplified for early events in EGF signaling. Availability and implementation: The Kappa platform is available via the project website at kappalanguage.org. All components of the platform are open source and freely available through the authors' code repositories.

Baseline connectome modular abnormalities in the childhood phase of a longitudinal study on individuals with chromosome 22q11.2 deletion syndrome.

Occurring in at least 1 in 3,000 live births, chromosome 22q11.2 deletion syndrome (22q11DS) produces a complex phenotype that includes a constellation of medical complications such as congenital cardiac defects, immune deficiency, velopharyngeal dysfunction, and characteristic facial dysmorphic features. There is also an increased incidence of psychiatric diagnosis, especially intellectual disability and ADHD in childhood, lifelong anxiety, and a strikingly high rate of schizophrenia spectrum disorders, which occur in around 30% of adults with 22q11DS. Using innovative computational connectomics, we studied how 22q11DS affects high-level network signatures of hierarchical modularity and its intrinsic geometry in 55 children with confirmed 22q11DS and 27 Typically Developing (TD) children. Results identified 3 subgroups within our 22q11DS sample using a K-means clustering approach based on several midline structural measures-of-interests. Each subgroup exhibited distinct patterns of connectome abnormalities. Subtype 1, containing individuals with generally healthy-looking brains, exhibited no significant differences in either modularity or intrinsic geometry when compared with TD. By contrast, the more anomalous 22q11DS Subtypes 2 and 3 brains revealed significant modular differences in the right hemisphere, while Subtype 3 (the most anomalous anatomy) further exhibited significantly abnormal connectome intrinsic geometry in the form of left-right temporal disintegration. Taken together, our findings supported an overall picture of (a) anterior-posteriorly differential interlobar frontotemporal/frontoparietal dysconnectivity in Subtypes 2 and 3 and (b) differential intralobar dysconnectivity in Subtype 3. Our ongoing studies are focusing on whether these subtypes and their connnectome signatures might be valid biomarkers for predicting the degree of psychosis-proneness risk found in 22q11DS.

Experiences of gestational diabetes and gestational diabetes care: a focus group and interview study.

BACKGROUND: Gestational diabetes mellitus (GDM) is an increasingly common condition of pregnancy. It is associated with adverse fetal, infant and maternal outcomes, as well as an increased risk of GDM in future pregnancies and type 2 diabetes for both mother and offspring. Previous studies have shown that GDM can result in an emotionally distressing pregnancy, but there is little research on the patient experience of GDM care, especially of a demographically diverse UK population. The aim of this research was to explore the experiences of GDM and GDM care for a group of women attending a large diabetes pregnancy unit in southeast London, UK, in order to improve care. METHODS: Framework analysis was used to support an integrated analysis of data from six focus groups with 35 women and semi-structured interviews with 15 women, held in 2015. Participants were purposively sampled and were representative of the population being studied in terms of ethnicity, age, deprivation score and body mass index (BMI). RESULTS: We identified seven themes: the disrupted pregnancy, projected anxiety, reproductive asceticism, women as baby machines, perceived stigma, lack of shared understanding and postpartum abandonment. These themes highlight the often distressing experience of GDM. While most women were grateful for the intensive support they received during pregnancy, the costs to their personal autonomy were high. Women described feeling valued solely as a means to produce a healthy infant, and felt chastised if they failed to adhere to the behaviours required to achieve this. This sometimes had an enduring impact to the potential detriment of women's long-term psychological and physical health. CONCLUSIONS: This study reveals the experiences of a demographically diverse group of patients with GDM, reflecting findings from previous studies globally and extending analysis to the context of improving care. Healthcare delivery may need to be reoriented to improve the pregnancy experience and help ensure women are engaged and attentive to their own health, particularly after birth, without compromising clinical pregnancy outcomes. Areas for consideration in GDM healthcare include: improved management of emotional responses to GDM; a more motivational approach; rethinking the medicalisation of care; and improved postpartum care.

Perceptions of insulin use in type 2 diabetes in primary care: a thematic synthesis.

BACKGROUND: Increasing numbers of patients with type 2 diabetes mellitus are progressing to insulin therapy, and despite its potency many such individuals still have suboptimal glycaemic control. Insulin initiation and intensification is now often conducted by Practice Nurses and General Practitioners in many parts of the UK. Therefore, gaining insight into perspectives of patients and primary care clinicians is important in determining self-management and engagement with insulin. A thematic synthesis of studies was conducted exploring the views and experiences of people with type 2 diabetes and of healthcare professionals on insulin use and management in the context of primary care. METHODS: Protocol based systematic searches of electronic databases (CINAHL, Cochrane Library, EMBASE, MEDLINE, PsycINFO, and Web of Science) were performed on 1 October 2014 and updated on 31 March 2015, to identify studies that identified the views and experiences of adults with type 2 diabetes or primary care clinicians on the use of insulin in the management of type 2 diabetes. Studies meeting the review inclusion criteria were critically appraised using the CASP qualitative research checklist or Barley's checklist for survey designs. A thematic synthesis was then conducted of the collected studies. RESULTS: Thirty-four studies were selected. Of these, 12 used qualitative interviews (nine with patients and three with healthcare professionals) and 22 were survey based (14 with patients, three with healthcare professionals, and five with both). Twelve key themes were identified and formed three domains, patient perceptions, healthcare professional perceptions, and health professional-patient relationships. The patient-centred themes were: insulin-related beliefs, social influences, psychological factors, hypoglycaemia, and therapy barriers. The clinician-related themes were: insulin skills of general practitioners, healthcare integration, healthcare professional-perceived barriers, hypoglycaemia, and explanations for adherence. Healthcare professional-patient relationship themes were drawn from the perspectives of patients and from clinicians. CONCLUSIONS: This review reveals multiple barriers to optimal insulin use in primary care at both the patient and healthcare professional levels. These barriers indicate the need for multimodal interventions to: improve the knowledge and competencies of primary care professionals in insulin use; provide more effective patient education and self-management support; and introduce integrated insulin support systems.

The Process of Adaptation Following a New Diagnosis of Type 1 Diabetes in Adulthood: A Meta-Synthesis.

While Type 1 diabetes (T1D) is generally associated with childhood, half of all cases occur in adulthood. The adaptive strategies individuals employ during the initial adaptive phase may have an important impact on their risk of future diabetes complications and their psychosocial well-being. We conducted a systematic review of six databases and included nine qualitative studies in a meta-synthesis, the aims of which were to develop a better understanding of how adults newly diagnosed with T1D experience the diagnosis and the phenomena associated with the early process of adaptation to life with diabetes. The meta-synthesis identified five constructs that shaped and influenced the early adaptive process: disruption, constructing a personal view of diabetes, reconstructing a view of self, learning to live with diabetes, and behavioral adaptations. The adaptive processes of adults to a diabetes diagnosis are highly referenced to prior life experiences, social habitus, and psychological orientation.

A taxonomy of visualization tasks for the analysis of biological pathway data.

BACKGROUND: Understanding complicated networks of interactions and chemical components is essential to solving contemporary problems in modern biology, especially in domains such as cancer and systems research. In these domains, biological pathway data is used to represent chains of interactions that occur within a given biological process. Visual representations can help researchers understand, interact with, and reason about these complex pathways in a number of ways. At the same time, these datasets offer unique challenges for visualization, due to their complexity and heterogeneity. RESULTS: Here, we present taxonomy of tasks that are regularly performed by researchers who work with biological pathway data. The generation of these tasks was done in conjunction with interviews with several domain experts in biology. These tasks require further classification than is provided by existing taxonomies. We also examine existing visualization techniques that support each task, and we discuss gaps in the existing visualization space revealed by our taxonomy. CONCLUSIONS: Our taxonomy is designed to support the development and design of future biological pathway visualization applications. We conclude by suggesting future research directions based on our taxonomy and motivated by the comments received by our domain experts.

Health professionals' personal behaviours hindering health promotion: A study of nurses who smoke.

AIM: To explore the views of current and ex-smoker nurses on their role in supporting patients to stop smoking. BACKGROUND: Long-term conditions are closely linked to harmful lifestyle behaviours, including smoking and overeating. Health professionals have an important role to play in promoting healthier lifestyles. It has been described that nurses' health behaviours may be a barrier to their health promotion practice. There is a need to gain further understanding on why nurses' health promotion activity is influenced by their own health behaviour. DESIGN: A secondary analysis of qualitative data gathered in 2010 in the context of a project that aimed to develop a smoking cessation intervention for nurses. METHODS: Eleven transcripts of semi-structured interviews conducted with nurses (current and ex-smokers) working in one university hospital in Spain. Data were analysed using framework analysis. FINDINGS: Nurses who smoked engaged in social justification in terms of social norms and work stress. Only nurses who had quit smoking were able to identify the negative feelings it generated and the effect that it had on their past health promotion practice. This was expressed by ex-smokers as an internal conflict that prevented them from supporting patients with their own habit. CONCLUSION: Nurses who smoke may be inhibited as health promoters without being aware of it. Interventions that focus on helping these professionals deal with the challenges associated with these encounters are necessary if health promotion practices are to be enhanced. Targeting this conflict might also work to improve their lifestyle, which would expand the potential impact to professionals' own health.

Perceptions among women with gestational diabetes.

Women with gestational diabetes are at high risk of developing type 2 diabetes, which could be prevented or delayed by lifestyle modification. Lifestyle interventions need to take into account the specific situation of women with gestational diabetes. We aimed to gain a deeper understanding of women's experiences of gestational diabetes, their diabetes risk perceptions, and their views on type 2 diabetes prevention, to inform future lifestyle interventions. We conducted a metasynthesis that included 16 qualitative studies and identified 11 themes. Factors that require consideration when developing a type 2 diabetes prevention intervention in this population include addressing the emotional impact of gestational diabetes; providing women with clear and timely information about future diabetes risk; and offering an intervention that fits with women's multiple roles as caregivers, workers, and patients, and focuses on the health of the whole family.
