Views of the public about Snacktivity™: a small changes approach to promoting physical activity and reducing sedentary behaviour.

BACKGROUND: Many people do not meet the recommended health guidance of participation in a minimum of 150-300 min of moderate intensity physical activity per week, often promoted as at least 30 min of physical activity on 5 days of the week. This is concerning and highlights the importance of finding innovative ways to help people to be physically active each day. Snacktivity™ is a novel approach that aims to encourage people to do small, 2-5 min bouts of physical activity 'snacks' throughout the whole day, such that they achieve at least 150 min of moderate intensity activity per week. However, before it can be recommended, there is a need to explore whether the concept is acceptable to the public. METHODS: A survey to assess the views of the public about Snacktivity™ was distributed to adult patients registered at six general practices in the West Midlands, UK and to health care employees in the same region. RESULTS: A total of 5989 surveys were sent to patients, of which 558 were returned (9.3%). A further 166 surveys were completed by health care employees. A total of 85% of respondents liked the Snacktivity™ concept. The flexibility of the approach was highly rated. A high proportion of participants (61%) reported that the ability to self-monitor their behaviour would help them to do Snacktivity™ throughout their day. Physically inactive participants perceived that Snacktivity™ would help to increase their physical activity, more than those who were physically active (OR = 0.41, 95% CI: 0.25-0.67). Approximately 90% of respondents perceived that Snacktivity™ was easy to do on a non-working day compared to 60% on a working day. Aerobic activity 'snacks' were preferred to those which were strength based. CONCLUSIONS: The Snacktivity™ approach to promoting physical activity was viewed positively by the public and interventions to test the merits of such an approach now need to be developed and tested in a variety of everyday contexts.

Experiences and perceptions of dietitians for obesity management: a general practice qualitative study.

BACKGROUND: Multi-component lifestyle interventions are the first line treatment for obesity. Dietitians are ideally placed healthcare professionals to deliver such interventions. However, only a small proportion of patients with obesity are referred by general practice to dietitians, and the reasons for this are not clear. The present study aimed to explore general practice healthcare professionals' (GPHCPs) experiences and perceptions of dietitians in the context of obesity management. METHODS: A convenience sample of GPHCPs practicing in the UK was recruited via a targeted social media strategy, using virtual snowball sampling. Data were collected using semi-structured interviews and analysed using framework analysis. RESULTS: In total, 20 participants were interviewed (11 general practice nurses and nine general practitioners). Experiences of referring patients with obesity for dietetic intervention resulted in two main themes: (i) access barriers and (ii) the dietetic consult experience. Three themes emerged from participants' perceptions of a role for general practice dietitians: (i) utilising dietetic expertise; (ii) access to dietitian; and (iii) time. Participants experienced barriers to accessing dietitians for obesity management and felt that having a dietitian working within their general practice team would help address this. Having a dietitian embedded within their general practice team was perceived to have the potential to alleviate GPHCPs' clinical time pressures, offer opportunities for upskilling, and may improve patient engagement with obesity management. CONCLUSIONS: GPHCPs perceived that embedding a dietitian within their general practice team would be valuable and beneficial for obesity management. Our findings provide support for the funding of general practice dietitian roles in the UK.

Development of a group structured education programme to support safe exercise in people with Type 1 diabetes: the EXTOD education programme.

AIM: To develop a structured education programme for individuals with Type 1 diabetes who are engaging in regular exercise. METHOD: A multidisciplinary team of experts in supporting exercise and physical activity for people with Type 1 diabetes, alongside researchers with experience of developing self-management education, developed an exercise programme using the Medical Research Council framework. The programme was informed by a review of the evidence relating to Type 1 diabetes and exercise, the behaviour change literature (including the behaviour change taxonomy), and qualitative interviews with stakeholders. The programme and supporting resources were refined using an iterative process of testing, delivery and collecting feedback from participants and the wider development team. RESULTS: The outcome of the intervention development was the design of a feasible and acceptable intervention for people with Type 1 diabetes to support safe exercise. The pilot allowed refinement of the intervention prior to testing in a two-site feasibility randomized controlled trial. Key findings from the pilot informed minor restructuring of the timetable (timings and order) and adaptation of supporting educational materials (participant handbook and teaching materials). CONCLUSION: The 'EXercise in people with Type One Diabetes' (EXTOD) education programme has been developed using robust methodology for the generation of educational interventions. It now needs testing in a randomized controlled trial.

Carbohydrate restriction for glycaemic control in Type 2 diabetes: a systematic review and meta-analysis.

AIM: To conduct a systematic review and meta-analysis to evaluate the effect of carbohydrate restriction on glycaemic control in Type 2 diabetes. METHODS: We searched Medline, EMBASE and CINAHL for the period between 1976 and April 2018. We included randomized controlled trials comparing carbohydrate restriction with a control diet which aimed to maintain or increase carbohydrate intake, and that reported HbA1c as an outcome and reported the amount of carbohydrate consumed during or at the end of the study, with outcomes reported at ≥3 months. RESULTS: We identified 1402 randomized controlled trials, 25 of which met the inclusion criteria, incorporating 2132 participants for the main outcome. Definitions of low carbohydrate varied among the studies. The pooled effect estimate from meta-analysis was a weighted mean difference of -0.09% [95% CI -0.27, 0.08 (P = 0.30); I2 72% (P <0.001)], suggesting no effect on HbA1c of restricting the quantity of carbohydrate. A subgroup analysis of diets containing 50-130 g carbohydrate resulted in a pooled effect estimate of -0.49% [95% CI -0.75, -0.23 (P <0.001); I2 0% (P = 0.56)], suggesting a clinically and statistically significant effect on HbA1c in favour of low-carbohydrate diets in studies of ≤6 months' duration. CONCLUSIONS: There was no overall pooled effect on HbA1c in favour of restricting carbohydrate; however, restriction of carbohydrate to 50-130 g per day had beneficial effects on HbA1c in trials up to 6 months. Future randomized controlled trials should be of >12 months' duration, assess pre-study carbohydrate intake, use recognized definitions of low-carbohydrate diets and examine reasons for non-adherence to prescribed diets in greater detail.

Exercise to preserve ß-cell function in recent-onset Type 1 diabetes mellitus (EXTOD) - a randomized controlled pilot trial.

AIM: Residual ß-cell function is present at the time of diagnosis with Type 1 diabetes. Preserving this ß-cell function reduces complications. We hypothesized that exercise preserves ß-cell function in Type 1 diabetes and undertook a pilot trial to address the key uncertainties in designing a definitive trial to test this hypothesis. METHODS: A randomized controlled pilot trial in adults aged 16-60 years diagnosed with Type 1 diabetes within the previous 3 months was undertaken. Participants were assigned to control (usual care) or intervention (exercise consultation every month), in a 1 : 1 ratio for 12 months. The primary outcomes were recruitment rate, drop out, exercise adherence [weeks with ≥ 150 min of self-reported moderate to vigorous physical activity (MVPA)], and exercise uptake in the control group. The secondary outcomes were differences in insulin sensitivity and rate of loss of ß-cell function between intervention and control at 6 and 12 months. RESULTS: Of 507 individuals who were approached, 58 (28 control, 30 intervention) entered the study and 41 completed it. Participants were largely white European males, BMI 24.8 ± 3.8 kg/m2 , HbA1c 75 ± 25 mmol/mol (9 ± 2%). Mean level of objectively measured MVPA increased in the intervention group (mean 243 to 273 min/week) and 61% of intervention participants reached the target of ≥ 150 min/week of self-reported MVPA on at least 42 weeks of the year. Physical activity levels fell slightly in the control group (mean 277 to 235 min of MVPA/week). There was exploratory evidence that intervention group became more insulin sensitive and required less insulin. However, the rate of loss of ß-cell function appeared similar between the groups, although the change in insulin sensitivity may have affected this. CONCLUSION: We show that it is possible to recruit and randomize people with newly diagnosed Type 1 diabetes to a trial of an exercise intervention, and increase and maintain their exercise levels for 12 months. Future trials need to incorporate measures of greater adherence to exercise training targets, and include more appropriate measures of ß-cell function. (Clinical Trials Registry No; ISRCTN91388505).

Dietitians' practice in giving carbohydrate advice in the management of type 2 diabetes: a mixed methods study.

BACKGROUND: Carbohydrate is accepted as the principal nutrient affecting blood glucose in diabetes; however, current guidelines are unable to specify the optimal quantity of carbohydrate for glycaemic control. No studies exist that describe current practice amongst healthcare professionals giving carbohydrate advice in type 2 diabetes. The present study aims to improve understanding of the degree of variation in the current practice of UK registered dietitians (RDs) by describing how RDs advise patients. METHODS: UK RDs were contacted through national networks and asked to complete an online survey, which was analysed using stata, version 12 (StataCorp, College Station, TX, USA). Three consultations between dietitians and patients with type 2 diabetes were observed, followed by semi-structured interviews with the dietitians. RESULTS: In total, 320 complete survey responses were received. Dietitians' advice varied according to expertise, training and confidence, and the complexity of the patient's blood glucose treatment. Some 48% (n = 154) of respondents advised patients to restrict carbohydrate intake either occasionally or frequently, with 35.6% (n = 114) considering 30-39% of total energy from carbohydrate to be a realistic expectation. The overall theme from the interviews was 'Conflicting Priorities', with three sub-themes: (i) how treatment decisions are made; (ii) the difference between empowerment and advice; and (iii) contradictory advice. A disparity existed between what was observed and interview data on how dietitians rationalise the type of carbohydrate advice provided. CONCLUSIONS: Dietitians' advice varies for a number of reasons. Consensus exists in some areas (e.g. carbohydrate awareness advice); however, clear definitions of such terms are lacking. Clarification of interventions may improve the consistency of approach and improve patient outcomes.

Prevalence and predictors of hospital prealerting in acute stroke: a mixed methods study.

BACKGROUND: Thrombolysis can significantly reduce the burden of stroke but the time window for safe and effective treatment is short. In patients travelling to hospital via ambulance, the sending of a 'prealert' message can significantly improve the timeliness of treatment. OBJECTIVE: Examine the prevalence of hospital prealerting, the extent to which prealert protocols are followed and what factors influence emergency medical services (EMS) staff's decision to send a prealert. METHODS: Cohort study of patients admitted to two acute stroke units in West Midlands (UK) hospitals using linked data from hospital and EMS records. A logistic regression model examined the association between prealert eligibility and whether a prealert message was sent. In semistructured interviews, EMS staff were asked about their experiences of patients with suspected stroke. RESULTS: Of the 539 patients eligible for this study, 271 (51%) were recruited. Of these, only 79 (29%) were eligible for prealerting according to criteria set out in local protocols but 143 (53%) were prealerted. Increasing number of Face, Arm, Speech Test symptoms (1 symptom, OR 6.14, 95% CI 2.06 to 18.30, p=0.001; 2 symptoms, OR 31.36, 95% CI 9.91 to 99.24, p<0.001; 3 symptoms, OR 75.84, 95% CI 24.68 to 233.03, p<0.001) and EMS contact within 5 h of symptom onset (OR 2.99, 95% CI 1.37 to 6.50 p=0.006) were key predictors of prealerting but eligibility for prealert as a whole was not (OR 1.92, 95% CI 0.85 to 4.34 p=0.12). In qualitative interviews, EMS staff displayed varying understanding of prealert protocols and described frustration when their interpretation of the prealert criteria was not shared by ED staff. CONCLUSIONS: Up to half of the patients presenting with suspected stroke in this study were prealerted by EMS staff, regardless of eligibility, resulting in disagreements with ED staff during handover. Aligning the expectations of EMS and ED staff, perhaps through simplified prealert protocols, could be considered to facilitate more appropriate use of hospital prealerting in acute stroke.

Preliminary results of a feasibility study of the use of information technology for identification of suspected colorectal cancer in primary care: the CREDIBLE study.

BACKGROUND: We report the findings of a feasibility study using information technology to search electronic primary care records and to identify patients with possible colorectal cancer. METHODS: An algorithm to flag up patients meeting National Institute for Health and Care Excellence (NICE) urgent referral criteria for suspected colorectal cancer was developed and incorporated into clinical audit software. This periodically flagged up such patients aged 60 to 79 years. General practitioners (GPs) reviewed flagged-up patients and decided on further clinical management. We report the numbers of patients identified and the numbers that GPs judged to need further review, investigations or referral to secondary care and the final diagnoses. RESULTS: Between January 2012 and March 2014, 19,580 records of patients aged 60 to 79 years were searched in 20 UK general practices, flagging up 809 patients who met urgent referral criteria. The majority of the patients had microcytic anaemia (236 (29%)) or rectal bleeding (205 (25%)). A total of 274 (34%) patients needed further clinical review of their records; 199 (73%) of these were invited for GP consultation, and 116 attended, of whom 42 were referred to secondary care. Colon cancer was diagnosed in 10 out of 809 (1.2%) flagged-up patients and polyps in a further 28 out of 809 (3.5%). CONCLUSIONS: It is technically possible to identify patients with colorectal cancer by searching electronic patient records.

A survey investigating the associations between self-management practices and quality of life in cancer survivors.

PURPOSE: To explore whether the use of self-management (SM) practices in cancer survivors impact on their health beliefs and quality of life (QoL). This is an important step in attempting to improve cancer survivors' health pathways and their experiences of living with cancer. METHODS: A cross-sectional, postal survey study was undertaken amongst cancer survivors identified from a teaching hospital in the West Midlands, UK. The questionnaire collected demographic data from respondents and information on the number and types of SM practices-diet, exercise, complementary and alternative medicine (CAM), psychological therapies, support groups and spirituality/religion-cancer survivors used after completing their treatment. Information was also gathered regarding their QoL and internal health locus of control (HLC). RESULTS: A total of 445 cancer survivors responded to the survey. Multi-linear regression analysis found a positive association between SM uptake and HLC; however, none was found between SM uptake and QoL. Treatment type, ethnicity and age were significantly associated with an increased use of SM practices. CONCLUSION: The study findings have implications for health care providers, who need to be aware of the links between SM uptake and treatment type, ethnicity and age, when considering how best to incorporate SM into cancer survivors' lives. This can help cancer survivors who may benefit from using specific SM interventions that consider the socio-demographic and treatment-related factors impacting on them. Future research would benefit from assessing the motivations and benefits of cancer survivors of different ages, ethnicities and treatment modalities in terms of their decision-making about SM use. These findings suggest that SM uptake is associated with higher internal HLC in cancer survivors. However, the influence of treatment type, ethnicity and age plays a more significant role in determining SM uptake than HLC. Cancer survivors using SM may be more motivated to utilise SM practices in relation to their age, ethnicity and treatment type, generating positive health outcomes in the process. Policy-makers should be aware of the supportive role SM interventions can play in cancer care and survivorship, with future research focussing on the perceived benefit of these SM interventions to cancer survivors.

Patterns of self-management practices undertaken by cancer survivors: variations in demographic factors.

The study purpose was to examine self-management (SM) use among cancer survivors; and to explore variations in uptake of SM in survivorship and whether these differed in relation to age, income, gender, ethnicity, cancer type and treatment type. This is an important area for exploration as SM utilisation has the potential to impact on the health status, health behaviours and quality of life (QoL) of cancer survivors. A postal survey was conducted among 445 cancer survivors identified from a hospital in the West Midlands, UK. Demographic data were collected and respondents were asked to identify which practices across six SM categories - diet, exercise, complementary and alternative medicine (CAM), psychological therapies, support groups and spirituality/religion - they had used (if any). The findings indicate that the large majority (91%) had used some form of SM after their cancer treatment. Exercise (84%) and diet (56%) were the most popular SM interventions for cancer survivors and socio-demographic and cancer-related factors were associated with SM uptake. These findings can form the basis for designing and implementing appropriate SM interventions aimed at improving the health, well-being and QoL of cancer survivors.

A qualitative exploration of the motives behind the decision to order a liver function test in primary care.

BACKGROUND: The number of tests ordered in primary care continues to increase influenced by a number of factors not all of which are concerned with diagnosis and management of disease. Liver function tests (LFTs) are a good example of inexpensive tests that are frequently ordered in patients with non-specific symptoms. They remain among the most frequently ordered tests despite their lack of specificity yet the full range of motives behind the decision to order an LFT remains unexplored. AIMS: To gain an understanding of the family practitioner's (FP) medical and non-medical motives for ordering an LFT and the influence of various social and technical factors on this decision. METHODS: We interviewed FPs across six practices who were participating in a prospective study of the efficacy of an abnormal LFT to indicate the development of a serious liver disease. Following content analysis of the data from the semi-structured interviews we used the 'attitude-social influence-efficacy' model to categorise the determinants of test ordering behaviour. RESULTS: Factors influencing an FP's decision to order a test were grouped into two broad categories; the first is 'internal' including expectation of efficacy and general attitude towards LFTs. The second group is 'external' and consists of themes of social influence, tests characteristics and defensive medicine. CONCLUSIONS: Whilst our sample acknowledged the clinical use of LFTs such as the routine monitoring of medication and liver-specific diagnostic purposes we also found that social and behavioural reasons are strong motivators to order an LFT and may take precedence over clinical factors.

An evaluation of in vivo voltage-sensitive dyes: pharmacological side effects and signal-to-noise ratios after effective removal of brain-pulsation artifacts.

In the current study, we investigated pharmacological side effects and signal-to-noise ratios (SNRs) of two commonly used voltage-sensitive dyes (VSDs): the blue dye RH-1691 (1 mg/ml) and the red dye di-4-ANEPPS (0.1 mg/ml), applied in vivo to the rat barrel cortex. Blue dyes are often favored over red dyes in in vivo studies due to their apparent superior SNR, partly because their fluorescence spectrum is farther away from the hemoglobin absorption spectrum, making them less prone to heartbeat-associated brain-pulsation artifacts (BPA). We implemented a previously reported template-based BPA removal algorithm and evaluated its applicability to di-4-ANEPPS before comparing characteristics of the two dyes. Somatosensory-evoked potentials (SEPs) were also recorded. Whereas SEPs recorded before and after application of di-4-ANEPPS failed to exhibit demonstrable differences, RH-1691 caused a significant and prolonged increase in SEP amplitude for several hours. In contrast, neither dye influenced the spontaneous cortical activity as assessed by the spectral content of the EEG. Both dyes turned out to be strikingly similar with respect to changes in fractional fluorescence as a function of SEP response amplitude, as well as regarding shot noise characteristics after removal of the BPA. Thus there is strong evidence that the increased SNR for RH-1691 is a consequence of an artificially increased signal. When applying an appropriate BPA removal algorithm, di-4-ANEPPS has proven to be suitable for single-trial in vivo VSD imaging (VSDI) and produces no detectable neurophysiological changes in the system under investigation. Taken together, our data argue for a careful re-evaluation of pharmacological side effects of RH-1691 and support the applicability of di-4-ANEPPS for stable single-trial in vivo VSDI recordings.

The use of herbal medicines by people with cancer: a cross-sectional survey.

BACKGROUND: A large proportion of cancer patients are estimated to use herbal medicines, but data to substantiate this are lacking. This study aimed to investigate the prevalence of herbal medicine use among cancer patients in the West Midlands, and determine the characteristics predicting herbal medicine use. METHODS: A cross-sectional survey of oncology patients (n=1498) being followed up at a hospital in Coventry was undertaken. Recipients were asked about herbal medicine use since their cancer diagnosis, and the association between sociodemographic and cancer-related characteristics and herbal medicine use was evaluated. RESULTS: A total of 1134 responses were received (75.7%). The prevalence of herbal medicine use was 19.7% (95% CI: 17.4-22.1; n=223). Users were more likely to be affluent, female, and aged under 50 years. Usage increased with time since cancer diagnosis (X(2) for trend=4.63; P=0.031). A validation data set, derived from a survey of oncology patients in Birmingham (n=541) with differing socioeconomic characteristics showed no significant difference in estimated prevalence (16.6%; 95% CI: 11.9-22.2). CONCLUSION: A substantial number of people with cancer are likely to be taking herbal medicines. Understanding the self-medication behaviours of these individuals is essential if health-care professionals are to support treatment adherence and avoid unwanted pharmacological interactions.

The use of symptoms to predict colorectal cancer site. Can we reduce the pressure on our endoscopy services?

OBJECTIVE: Our objective was to determine the value of gastrointestinal symptoms and signs in predicting the site of colorectal cancer (CRC). These symptoms can subsequently be used in determining first-line investigation with either sigmoidoscopy or colonoscopy. METHOD: We interrogated the endoscopic and CRC databases ('Infoflex'), for patients diagnosed with CRC between April 2005 and March 2006 inclusive. These patients were cross-referenced with the pathology database and patient records. Information gathered from these databases include: age, gender, symptoms, site of cancer, histology, Duke's grading, blood parameters, diagnostic tool and treatment. RESULTS: One hundred fifty-three patients were diagnosed with CRC between April 2005 and March 2006. One hundred twenty-six were initially seen in the out-patient department, of whom 38 (29%) were right-sided (proximal to the splenic flexure), and 88 (70%) were left-sided (splenic flexure and beyond). Change in bowel habit (diarrhoea and constipation) and rectal bleeding were significantly associated with left-sided cancers (P < 0.0024 and P < 0.0001, respectively). Haemoglobin (P < 0.0001) and mean corpuscular volume (P < 0.0001) were significantly lower in right-sided cancers. Weight loss, pain and obstruction were not associated with cancer site. C-reactive protein, albumin and carcinoembryonic antigen are not predictive of cancer site, Duke's stage or influenced by patient age or gender. DISCUSSION: Symptoms can accurately predict site of cancer, allowing investigations to be tailored accordingly. We would recommend that patients with altered bowel habit and/or rectal bleeding, and no other symptoms, risk factors or anaemia, can be investigated with a flexible sigmoidoscopy to confirm or refute a diagnosis of colorectal cancer.

Why members of the public self-test: an interview study.

BACKGROUND: A wide range of self-tests are available where contact with a health professional is not necessary. OBJECTIVE: To investigate factors that influenced members of the public to use self-tests. METHODS: Questionnaires, sent to 2335 adults from two general practices in North Birmingham, asked whether recipients had used self-tests and sought consent for contacting them about taking part in an interview. Twenty-three people were interviewed, 20 of whom had used self-tests. The interviews were transcribed verbatim, and a thematic analysis was conducted. RESULTS: The findings were organized around two themes. 'Motivations for self-testing' describes the motivating factors surrounding participants' choices to use self-tests. This appeared to be influenced by a number of factors that were organized into four sub-themes: 'diagnosis or speculation', 'perceived benefits of self-testing', 'general attitudes to and experiences of health care' and 'general attitudes to health'. The second theme called 'experience of self-testing' describes participants' access to, and use of self-tests, and is split into three sub-themes: 'opportunistic awareness and access', 'use and application' and 'impact on life'. CONCLUSIONS: Overall, self-testing encompasses a broad variety of beliefs and experiences. Some participants saw self-tests as a serious diagnostic tool, whereas others used them out of simple curiosity. Some were motivated by their generally positive attitude to health, but others may have been motivated by negative health care experiences. Some saw self-testing as an empowering process to be proud of, while others seemed to view it as an illegitimate activity that needed to be hidden from professionals.

Healthcare workers' perceptions of the duty to work during an influenza pandemic.

Healthcare workers (HCWs) are often assumed to have a duty to work, even if faced with personal risk. This is particularly so for professionals (doctors and nurses). However, the health service also depends on non-professionals, such as porters, cooks and cleaners. The duty to work is currently under scrutiny because of the ongoing challenge of responding to pandemic influenza, where an effective response depends on most uninfected HCWs continuing to work, despite personal risk. This paper reports findings of a survey of HCWs (n = 1032) conducted across three National Health Service trusts in the West Midlands, UK, to establish whether HCWs' likelihood of working during a pandemic is associated with views about the duty to work. The sense that HCWs felt that they had a duty to work despite personal risk emerged strongly regardless of professional status. Besides a strong sense that everyone should pull together, all kinds of HCWs recognised a duty to work even in difficult circumstances, which correlated strongly with their stated likelihood of working. This suggests that HCWs' decisions about whether or not they are prepared to work during a pandemic are closely linked to their sense of duty. However, respondents' sense of the duty to work may conflict with their sense of duty to family, as well as other factors such as a perceived lack of reciprocity from their employers. Interestingly, nearly 25% of doctors did not consider that they had a duty to work where doing so would pose risks to themselves or their families.

Prevalence of the use of self-tests by adults in the United Kingdom: a questionnaire survey.

BACKGROUND: Self-tests that people can do without a health professional are widely available, but there is little information about how many people have used one. Our aim was to describe the prevalence of use. METHODS: An initial questionnaire, sent to 8048 adults registered with six general practices in North Birmingham and Warwickshire and Worcestershire, asked whether the person had self-tested. A second questionnaire validated the use for people from the final four practices by asking how each self-test had been obtained and why it had been used. RESULTS: The age-standardised prevalence of confirmed use for any self-test other than for pregnancy or high blood pressure was 47 (95% confidence interval (CI): 37-57) per 1000 women and 22 (95% CI: 14-30) per 1000 men. If everyone who initially reported use but did not return an eligible second questionnaire had the same rates of confirmed use as eligible responders, this would increase to 95 (95% CI: 81-110) per 1000 women and 55 (95% CI: 41-68) per 1000 men. CONCLUSION: An appreciable minority of the population have self-tested for medical conditions.

Aortocaval fistula, a potentially favourable complication of abdominal aortic aneurysm rupture in endovascular repair.

Endovascular aneurysm repair is an established treatment for ruptured abdominal aortic aneurysm. Primary aortocaval fistula is an exceedingly rare finding in ruptured abdominal aortic aneurysm, with a reported incidence of less than 1%. The presence of an aortocaval fistula used to be an unexpected finding in open surgical repair which often resulted in massive haemorrhage and caval injury. We present a case of ruptured abdominal aortic aneurysm with an aortocaval fistula that was successfully treated with percutaneous endovascular aneurysm repair under local anaesthesia. Despite a persistent type 2 endoleak the aneurysm sack shrank from 8.4cm to 4.8cm in 12 months. The presence of an aortocaval fistula may have depressurised the aneurysm, resulting in less bleeding retroperitoneally and may have promoted rapid shrinkage of the sac despite the presence of a persistent type 2 endoleak.

Feasibility and acceptability of a brief routine weight management intervention for postnatal women embedded within the national child immunisation programme in primary care: randomised controlled cluster feasibility trial.

BACKGROUND: The prevalence of obesity in women continues to rise and pregnancy is a high-risk time for excessive weight gain. The period after childbirth represents an opportunity to offer women support to manage their weight. The primary aim here was to investigate the acceptability and feasibility of delivering a self-management intervention to postnatal women to support weight loss, embedded within the national child immunisation programme. METHODS: The research involved a randomised controlled cluster feasibility trial. Data were collected at baseline and 3 months later. Twenty-eight postnatal women living with overweight or obesity were recruited via Birmingham Women Hospital or general practices. Babies are routinely immunised at 2, 3 and 4 months of age; the intervention was embedded within these appointments. The intervention involved brief motivation/support by practice nurses to encourage participants to make healthier lifestyle choices through self-monitoring of weight and signposting to an online weight management programme, when they attended their practice to have their child immunised. The role of the nurse was to provide external accountability for weight loss. Participants were asked to weigh themselves weekly and record this on a record card or using the online programme. The weight goal was for participants to lose 0.5 to 1 kg per week. Usual care received a healthy lifestyle leaflet. The primary outcome was the feasibility of a phase III trial to test the subsequent effectiveness of the intervention, as assessed against three stop-go traffic light criteria (recruitment, adherence to regular self-weighing and registration with an online weight management programme). RESULTS: The traffic light stop-go criteria results were red for recruitment (28/80, 35% of target), amber for registration with the online weight loss programme (9/16, 56%) and green for adherence to weekly self-weighing (10/16, 63%). Nurses delivered the intervention with high fidelity. DISCUSSION: Whilst participants and nurses followed the trial protocol well and adherence to self-weighing was acceptable, recruitment was challenging and there is scope to improve engagement with the online weight management programme component of the intervention. TRIAL REGISTRATION: ISRCTN 12209332 . Registration date is 04/12/18.

Wheat Leaf Rust: Control by 4-n-Butyl-1,2,4-triazole, a Systemic Fungicide.

Compound 4-n-butyl-1,2,4-triazole was demonstrated as an enduring and selective systemic fungicide for the control of wheat leaf rust by foliar and soil applications. Among several species of rust fungi treated, only wheat leaf rust (Puccinia recondita Rob.) was controlled. Wheat stem rust, for example, was unaffected by either soil or foliar applications.
