RESUMEN
Renal artery aneurysms (RAA) have an increased risk of rupture during pregnancy with high mortality rates for the mother and fetus. There are many reports on the treatment of ruptured RAA during pregnancy and the Society for Vascular Surgery recommends to prophylactically treat unruptured RAA of any size in women of reproductive age to limit risk of rupture during pregnancy. However, to the best of our knowledge, there is no reported case of prophylactic treatment of unruptured RAA during pregnancy. Here we report the case of a 39-year-old G2P1 who had prophylactic endovascular coiling of an unruptured left RAA during her second trimester of pregnancy. Our case report is the first to demonstrate that unruptured RAA can be safely intervened endovascularly to prevent rupture without disrupting the pregnancy.

A 39-year-old woman presented with bleeding 4 months after a surgical termination of pregnancy. Persistent beta-human chorionic gonadotropin levels were suggestive of retained products of conception (RPOC). However, multimodal imaging revealed a concurrent uterine arteriovenous malformation (AVM). Although most stable AVMs can be managed conservatively, the need for surgical management of chronic RPOC and consequential hemorrhage risk complicates this approach. Patient-determined management prioritized blood conservation while minimizing risks to fertility. This case is discussed with respect to the rare concurrent existence of RPOC and AVM. Little is known regarding the optimal tandem therapeutic approach. As depicted, successful treatment requires careful diagnostic workup and a multidisciplinary approach.

BACKGROUND: Medication-related errors are one of the most frequently reported incidents in hospitals. With the aim of reducing the medication error rate, a Partnered Pharmacist Medication Charting (PPMC) model was trialled in seven Australian hospitals from 2016 to 2017. Participating pharmacists completed a credentialing program to equip them with skills to participate in the trial as a medication-charting pharmacist. Skills included obtaining a comprehensive medication history to chart pre-admission medications in collaboration with an admitting medical officer. The program involved both theoretical and practical components to assess the competency of pharmacists. METHODS: A qualitative evaluation of the multi-site PPMC implementation trial was undertaken. Pharmacists and key informants involved in the trial participated in an interview or focus group session to share their experiences and attitudes regarding the PPMC credentialing program. An interview schedule was used to guide sessions. Transcripts were analysed using a pragmatic inductive-deductive thematic approach. RESULTS: A total of 125 participants were involved in interviews or focus groups during early and late implementation data collection periods. Three themes pertaining to the PPMC credentialing program were identified: (1) credentialing as an upskilling opportunity, (2) identifying the essential components of credentialing, and (3) implementing and sustaining the PPMC credentialing program. CONCLUSIONS: The PPMC credentialing program provided pharmacists with an opportunity to expand their scope of practice and consolidate clinical knowledge. Local adaptations to the PPMC credentialing program enabled pharmacists to meet the varying needs and capacities of hospitals, including the policies and procedures of different clinical settings. These findings highlight key issues to consider when implementation a credentialing program for pharmacists in the hospital setting.

BACKGROUND: Emergency front of neck airway access by anaesthetists carries a high failure rate and it is recommended to identify the cricothyroid membrane before induction of anaesthesia in patients with a predicted difficult airway. We have investigated whether a marking of the cricothyroid membrane done in the extended neck position remains correct after the patient's neck has been manipulated and subsequently repositioned. METHODS: The subject was first placed in the extended head and neck position and had the cricothyroid membrane identified and marked with 3 methods, palpation, 'laryngeal handshake' and ultrasonography and the distance from the suprasternal notch to the cricothyroid membrane was measured. The subject then moved off the table and sat on a chair and subsequently returned to the extended neck position and examinations were repeated. RESULTS: Skin markings of all 11 subjects lay within the boundaries of the cricothyroid membrane when the subject was repositioned back to the extended neck position and the median difference between the two measurements of the distance from the suprasternal notch was 0 mm (range 0-2 mm). CONCLUSION: The cricothyroid membrane can be identified and marked with the subject in the extended neck position. Then the patient's position can be changed as needed, for example to the 'sniffing' neck position for conventional intubation. If a front of neck airway access is required during subsequent airway management, the patient can be returned expediently to the extended-neck position, and the marking of the centre of the membrane will still be in the correct place.

BACKGROUND AND PURPOSE: Oral anticoagulants (OAC) substantially reduce risk of stroke in atrial fibrillation, but uptake is suboptimal. Electronic health records enable automated identification of people at risk but not receiving treatment. We investigated the effectiveness of a software tool (AURAS-AF [Automated Risk Assessment for Stroke in Atrial Fibrillation]) designed to identify such individuals during routine care through a cluster-randomized trial. METHODS: Screen reminders appeared each time the electronic health records of an eligible patient was accessed until a decision had been taken over OAC treatment. Where OAC was not started, clinicians were prompted to indicate a reason. Control practices continued usual care. The primary outcome was the proportion of eligible individuals receiving OAC at 6 months. Secondary outcomes included rates of cardiovascular events and reports of adverse effects of the software on clinical decision-making. RESULTS: Forty-seven practices were randomized. The mean proportion-prescribed OAC at 6 months was 66.3% (SD=9.3) in the intervention arm and 63.9% (9.5) in the control arm (adjusted difference 1.21% [95% confidence interval -0.72 to 3.13]). Incidence of recorded transient ischemic attack was higher in the intervention practices (median 10.0 versus 2.3 per 1000 patients with atrial fibrillation; P=0.027), but at 12 months, we found a lower incidence of both all cause stroke (P=0.06) and hemorrhage (P=0.054). No adverse effects of the software were reported. CONCLUSIONS: No significant change in OAC prescribing occurred. A greater rate of diagnosis of transient ischemic attack (possibly because of improved detection or overdiagnosis) was associated with a reduction (of borderline significance) in stroke and hemorrhage over 12 months.

OBJECTIVE: To determine whether paper tape prevents foot blisters in multistage ultramarathon runners. DESIGN: Multisite prospective randomized trial. SETTING: The 2014 250-km (155-mile) 6-stage RacingThePlanet ultramarathons in Jordan, Gobi, Madagascar, and Atacama Deserts. PARTICIPANTS: One hundred twenty-eight participants were enrolled: 19 (15%) from the Jordan, 35 (27%) from Gobi, 21 (16%) from Madagascar, and 53 (41%) from the Atacama Desert. The mean age was 39.3 years (22-63) and body mass index was 24.2 kg/m (17.4-35.1), with 31 (22.5%) females. INTERVENTIONS: Paper tape was applied to a randomly selected foot before the race, either to participants' blister-prone areas or randomly selected location if there was no blister history, with untaped areas of the same foot used as the control. MAIN OUTCOME MEASURES: Development of a blister anywhere on the study foot. RESULTS: One hundred six (83%) participants developed 117 blisters, with treatment success in 98 (77%) runners. Paper tape reduced blisters by 40% (P < 0.01, 95% confidence interval, 28-52) with a number needed to treat of 1.31. Most of the study participants had 1 blister (78%), with most common locations on the toes (n = 58, 50%) and heel (n = 27, 23%), with 94 (80%) blisters occurring by the end of stage 2. Treatment success was associated with earlier stages [odds ratio (OR), 74.9, P < 0.01] and time spent running (OR, 0.66, P = 0.01). CONCLUSION: Paper tape was found to prevent both the incidence and frequency of foot blisters in runners.

PURPOSE: The purpose of this study was to examine the association between the prevalence of both diabetes-concordant and diabetes-discordant conditions and the quality of diabetes care at the family practice level in England. We hypothesized that the prevalence of concordant (or discordant) conditions would be associated with better (or worse) quality of diabetes care. METHODS: We conducted a cross-sectional study using practice-level data (7,884 practices). We estimated the practice-level prevalence of diabetes and 15 other chronic conditions, which were classified as diabetes concordant (ie, with the same pathophysiologic risk profile and therefore more likely to be part of the same management plan) or diabetes discordant (ie, not directly related in either their pathogenesis or management). We measured quality of diabetes care with diabetes-specific indicators (8 processes and 3 intermediate outcomes of care). We used linear regression models to quantify the effect of the prevalence of the conditions on aggregate achievement rate for quality of diabetes care. RESULTS: Consistent with the proposed model, the prevalence rates of 4 of 7 concordant conditions (obesity, chronic kidney disease, atrial fibrillation, heart failure) were positively associated with quality of diabetes care. Similarly, negative associations were observed as predicted for 2 of the 8 discordant conditions (epilepsy, mental health). Observations for other concordant and discordant conditions did not match predictions in the hypothesized model. CONCLUSIONS: The quality of diabetes care provided in English family practices is associated with the prevalence of other major chronic conditions at the practice level. The nature and direction of the observed associations cannot be fully explained by the concordant-discordant model.

BACKGROUND: Falls among older people are of growing concern globally. Implementing cost-effective strategies for their prevention is of utmost importance given the ageing population and associated potential for increased costs of fall-related injury over the next decades. The purpose of this study was to undertake a cost-utility analysis and secondary cost-effectiveness analysis from a healthcare system perspective, of a group-based exercise program compared to routine care for falls prevention in an older community-dwelling population. METHODS: A decision analysis using a decision tree model was based on the results of a previously published randomised controlled trial with a community-dwelling population aged over 70. Measures of falls, fall-related injuries and resource use were directly obtained from trial data and supplemented by literature-based utility measures. A sub-group analysis was performed of women only. Cost estimates are reported in 2010 British Pound Sterling (GBP). RESULTS: The ICER of GBP£51,483 per QALY for the base case analysis was well above the accepted cost-effectiveness threshold of GBP£20,000 to £30,000 per QALY, but in a sensitivity analysis with minimised program implementation the incremental cost reached GBP£25,678 per QALY. The ICER value at 95% confidence in the base case analysis was GBP£99,664 per QALY and GBP£50,549 per QALY in the lower cost analysis. Males had a 44% lower injury rate if they fell, compared to females resulting in a more favourable ICER for the women only analysis. For women only the ICER was GBP£22,986 per QALY in the base case and was below the cost-effectiveness threshold for all other variations of program implementation. The ICER value at 95% confidence was GBP£48,212 in the women only base case analysis and GBP£23,645 in the lower cost analysis. The base case incremental cost per fall averted was GBP£652 (GBP£616 for women only). A threshold analysis indicates that this exercise program cannot realistically break even. CONCLUSIONS: The results suggest that this exercise program is cost-effective for women only. There is no evidence to support its cost-effectiveness in a group of mixed gender unless the costs of program implementation are minimal. Conservative assumptions may have underestimated the true cost-effectiveness of the program.

This Letter demonstrates polarization spectroscopy of a velocity selected and vibrationally excited molecular sample. Specifically, the anisotropy induced by a circularly polarized IR pump beam tuned to the R(14.5)(1/2)v=1âv=0 transition of nitric oxide is observed using an IR probe resonant with the R(15.5)(1/2)v=2âv=1 hot band transition. Using two detectors in combination with the rapidly swept probe allows both the absorptive and dispersive components of the excited state polarization to be observed for the first time. The data are well described by simulations based upon a three-level density matrix model.
RESUMEN
This paper details infra-red pump and probe studies on nitric oxide conducted with two continuous wave quantum cascade lasers both operating around 5 µm. The pump laser prepares a velocity selected population in a chosen rotational quantum state of the v = 1 level which is subsequently probed using a second laser tuned to a rotational transition within the v = 2 â v = 1 hot band. The rapid frequency scan of the probe (with respect to the molecular collision rate) in combination with the velocity selective pumping allows observation of marked rapid passage signatures in the transient absorption profiles from the polarized vibrationally excited sample. These coherent transient signals are influenced by the underlying hyperfine structure of the pump and probe transitions, the sample pressure, and the coherent properties of the lasers. Pulsed pump and probe studies show that the transient absorption signals decay within 1 µs at 50 mTorr total pressure, reflecting both the polarization and population dephasing times of the vibrationally excited sample. The experimental observations are supported by simulation based upon solving the optical Bloch equations for a two level system.
RESUMEN
OBJECTIVES: There are marked inequalities in cardiovascular disease (CVD) incidence and outcomes between ethnic groups. CVD risk scores are increasingly used in preventive medicine and should aim to accurately reflect differences between ethnic groups. Ethnicity, as an independent risk factor for CVD, can be accounted for in CVD risk scores primarily using two methods, either directly incorporating it as a risk factor in the algorithm or through a post hoc adjustment of risk. We aim to compare these two methods in terms of their prediction of CVD across ethnic groups using representative national data from England. DESIGN: A cross-sectional study using data from the Health Survey for England. We measured ethnic group differences in risk estimation between the QRISK2, which includes ethnicity and Joint British Societies 2 (JBS2) algorithm, which uses post hoc risk adjustment factor for South Asian men. RESULTS: The QRISK2 score produces lower median estimates of CVD risk than JBS2 overall (6.6% [lower quartile-upper quartile (LQ-UQ)=4.0-18.6] compared with 9.3% [LQ-UQ=2.3-16.9]). Differences in median risk scores are significantly greater in South Asian men (7.5% [LQ-UQ=3.6-12.5]) compared with White men (3.0% [LQ-UQ=0.7-5.9]). Using QRISK2, 19.1% [95% confidence interval (CI)=16.2-22.0] fewer South Asian men are designated at high risk compared with 8.8% (95% CI=5.9-7.8) fewer in White men. Across all ethnic groups, women had a lower median QRISK2 score (0.72 [LQ-UQ=- 0.6 to 2.13]), although relatively more (2.0% [95% CI=1.4-2.6]) were at high risk than with JBS2. CONCLUSIONS: Ethnicity is an important CVD risk factor. Current scoring tools used in the UK produce significantly different estimates of CVD risk within ethnic groups, particularly in South Asian men. Work to accurately estimate CVD risk in ethnic minority groups is important if CVD prevention programmes are to address health inequalities.

OBJECTIVE: We aimed to assess whether the National Health Service (NHS) Health Check, a systematic cardiovascular disease (CVD) risk assessment and management program, was associated with reduction in CVD risk in attendees after one year. METHODS: We extracted data from patients aged 40-74 years, with high estimated CVD risk, who were registered with general practices in a deprived, culturally diverse setting in England. We included 4748 patients at baseline (July 2008-November 2009), with 3712 at follow-up (December 2009-March 2011). We used a pre-post study design to assess changes in global CVD risk, individual CVD risk factors and statin prescription in patients with a complete and partial Health Check. RESULTS: There were significant reductions in mean CVD risk score (28.2%; 95% confidence interval (CI)=27.3-29.1 to 26.2%; 95% CI, 25.4-27.1), diastolic blood pressure, total cholesterol levels and lipid ratios after one year in patients with a complete Health Check. Statin prescription increased from 14.0% (95% CI=11.9-16.0) to 60.6% (95% CI=57.7-63.5). CONCLUSIONS: The introduction of NHS Health Check was associated with significant but modest reductions in CVD risk among screened high-risk individuals. Further cost-effectiveness analysis and work accounting for uptake is required to assess whether the program can make significant changes to population health.

BACKGROUND: The NHS Health Check programme aims to improve prevention, early diagnosis and management of cardiovascular disease (CVD) in England. High and equitable uptake is essential for the programme to effectively reduce the CVD burden. OBJECTIVES: Assessing the impact of a local financial incentive scheme on uptake and statin prescribing in the first 2 years of the programme. METHODS: Cross-sectional study using data from electronic medical records of general practices in Hammersmith and Fulham, London on all patients aged 40-74 years. We assessed uptake of complete Health Check, exclusion of patients from the programme (exception reporting) and statin prescriptions in patients confirmed with high CVD risk. RESULTS: The Health Check uptake was 32.7% in Year 1 and 20.0% in Year 2. Older patients had higher uptake of Health Check than younger (65- to 74-year-old patients: Year 1 adjusted odds ratio (AOR) 2.05 (1.67-2.52) & Year 2 AOR 2.79 (2.49-3.12) compared with 40- to 54-year-old patients). The percentage of confirmed high risk patients prescribed a statin was 17.7% before and 52.9% after the programme. There was a marked variation in Health Check uptake, exception reporting and statin prescribing between practices. CONCLUSIONS: Uptake of the Health Check was low in the first year in patients with estimated high risk despite financial incentives to general practices; although this matched the national required rate in second year. Further evaluations for cost and clinical effectiveness of the programme are needed to clarify whether this spending is appropriate, and to assess the impact of financial incentives on programme performance.

BACKGROUND: This study was undertaken to estimate utility values for alternative treatment intervals for long acting antipsychotic intramuscular injections for the treatment of schizophrenia. METHODS: Vignettes were developed using the published literature and an iterative consultation process with expert clinicians and patient representative groups. Four vignettes were developed. The first was a vignette of relapsed/untreated schizophrenia. The other three vignettes presented a standardised picture of well-managed schizophrenia with variations in the intervals between injections: once every 2-weeks, 4-weeks and 3-months. A standardised time trade off (TTO) approach was used to obtain utility values for the vignettes. As a societal perspective was sought, a representative sample of individuals from across the community (Sydney, Australia) was recruited. Ninety-eight people completed the TTO interview. The vignettes were presented in random order to prevent possible ordering effects. RESULTS: A clear pattern of increasing utility was observed with increasing time between injections. Untreated schizophrenia was rated as very poor health-related quality of life with a mean (median) utility of 0.27 (0.20). The treated health states were rated at much higher utilities and were statistically significantly different (p < 0.001) from each other: (1) 2-weekly: mean (median) utility = 0.61 (0.65); (2) 4-weekly: mean (median) utility = 0.65 (0.70); (3) 3-monthly: mean (median) utility = 0.70 (0.75). CONCLUSIONS: This study has provided robust data indicating that approximately a 0.05 utility difference exists between treatment options, with the highest utility assigned to 3-monthly injections.

BACKGROUND: National Health Service (NHS) Health Checks, a population-wide prevention programme introduced during 2009, aims to measure and manage cardiovascular disease (CVD) risk factors among all persons aged 40-74 years in England. The potential workload implications of the programme for general practice are considerable, particularly in deprived culturally diverse settings. OBJECTIVE: To examine the baseline levels of CVD risk factor recording in general practices located in Ealing, North West London. METHODS: Cross-sectional study using data extracted from electronic medical records in 14 general practices between December 2008 and January 2009. The completeness of blood pressure, smoking, body mass index (BMI) and cholesterol recording was examined by practice and patient characteristics. RESULTS: Recording of blood pressure [85.6% (practice interquartile range = 10.1)] and smoking status [95.8% (2.6)] was very high in practices. Recording of BMI [72.8% (23.4)] and cholesterol [55.6% (25.3)] was considerably lower. There were large differences in recording between practices (range for cholesterol: 33.6-78.0%), though these were largely explained by patient characteristics. In regression analysis, hypertensive patients [adjusted odds ratio (AOR) = 36.3, 95% confidence interval (CI) 21.0-62.9], women [AOR = 2.88 (95% CI 2.64-3.15)] and older patients [AOR = 2.75 (95% CI 2.28-3.32) for 65-74 against 35-44 years of age] had better recording of blood pressure as well as BMI and cholesterol. Recording of blood pressure [AOR = 1.38 (95% CI 1.09-1.75)] and cholesterol [AOR = 1.47 (95% CI 1.30-1.66)] was significantly higher among South Asian patients. CONCLUSIONS: The workload implications of the NHS Health Checks programme for general practices in England are substantial. There are considerable variations in risk factor recording between practices and between age, gender and ethnic groups.

BACKGROUND: The UK is embarking on a national cardiovascular risk assessment programme called NHS Health Checks; in order to be effective, high and equitable uptake is paramount. METHODS: A cross-sectional study, using data extracted from electronic medical records of persons aged 35-74 years estimated to be at a high risk of developing cardiovascular disease, to examine the uptake of the Health Checks using logistic regression and statin prescribing. RESULTS: A total of 44.8% of high risk patients invited for a Health Check attended. Uptake was lower among younger men but higher among patients from south Asian (AOR = 1.71 [1.29-2.27] compared with white) or mixed ethnic backgrounds (AOR = 2.42 [1.50-3.89]), and patients registered with smaller practices (AOR = 2.53 [1.09-5.84] <3000 patients compared with 3000-5999). The percentage of patients confirmed to be at high risk of CVD prescribed a statin increased from 24.7 to 44.8%. CONCLUSIONS: Uptake of cardiovascular risk assessment and prescribing of statins in high risk patients was considerably lower than projected in the first year of NHS Health Checks programme. Targeting efforts to increase uptake and adherence to interventions in high risk populations and reinvesting resources into population wide strategies to reduce obesity, smoking and salt intake may prove more cost-effective in reducing the burden of cardiovascular disease in the UK.

BACKGROUND: Risperidone long-acting injection (LAI) is mostly administered twice weekly to people with schizophrenia by nurses at community mental health centres (CMHC) or through mobile outreach visits. This study estimates the cost of resource utilisation associated with the administration of risperidone LAI and the potential savings from substituting two-weekly injections with a longer interval product of therapeutic equivalence. METHODS: A survey of mental health staff overseeing the administration of risperidone LAI at 253 distinct Australian CMHCs was undertaken in November 2009. For the two-week period prior to the survey, respondents were asked questions on injection time (and related tasks) and, for mobile outreach visits, distance and time travelled as well as reduction in visits. Results were stratified by Australian Standard Geographical Classification (ASGC) region. Resource use was quantified and valued in Australian dollars. RESULTS: Results are derived from 74 CMHCs, representing approximately 26% of the national average risperidone LAI unit two-week sales. Stratified average injection time (including related tasks) for risperidone LAI ranged from 18-29 minutes, with a national average of 20.12 minutes. For mobile outreach visits, average distance per patient ranged from 19.4 to 55.5 km for One Staff Visits and 15.2 to 218.1 km for More Than One Staff Visits, and average time travelled ranged from 34.1 to 54.5 minutes for One Staff Visits and 29.2 to 136.3 minutes for More Than One Staff visits. The upper range consistently reflected greater resource utilisation in rural areas compared to urban areas. If administration of risperidone LAI had not been required, 20% fewer mobile outreach visits would have occurred. CONCLUSIONS: The national average saving per two-weekly risperidone long-acting injection avoided is $75.14. In 2009 in Australia, this would have saved ~$11 million for injection administration costs alone if all patients taking two-weekly risperidone LAI had instead been treated with a therapeutically equivalent long-acting injectable antipsychotic requiring one less injection per month.

BACKGROUND: Targeted screening for cardiovascular disease (CVD) can be carried out using existing data from patient medical records. However, electronic medical records in UK general practice contain missing risk factor data for which values must be estimated to produce risk scores. OBJECTIVE: To compare two methods of substituting missing risk factor data; multiple imputation and the use of default National Health Survey values. METHODS: We took patient-level data from patients in 70 general practices in Ealing, North West London. We substituted missing risk factor data using the two methods, applied two risk scores (QRISK2 and JBS2) to the data and assessed differences between methods. RESULTS: Using multiple imputation, mean CVD risk scores were similar to those using default national survey values, a simple method of imputation. There were fewer patients designated as high risk (>20%) using multiple imputation, although differences were again small (10.3% compared with 11.7%; 3.0% compared with 3.4% in women). Agreement in high-risk classification between methods was high (Kappa = 0.91 in men; 0.90 in women). CONCLUSIONS: A simple method of substituting missing risk factor data can produce reliable estimates of CVD risk scores. Targeted screening for high CVD risk, using pre-existing electronic medical record data, does not require multiple imputation methods in risk estimation.

BACKGROUND: Adult febrile neutropenic oncology patients, at low risk of developing medical complications, may be effectively and safely managed in an ambulatory setting, provided they are appropriately selected and adequate supportive facilities and clinical services are available to monitor these patients and respond to any clinical deterioration. METHODS: A cost analysis was modelled using decision tree analysis, published cost and effectiveness parameters for ambulatory care strategies and data from the State of Victoria's hospital morbidity dataset. Two-way sensitivity analyses and Monte Carlo simulation were performed to evaluate the uncertainty of costs and outcomes associated with ambulatory care. RESULTS: The modelled cost analysis showed that cost savings for two ambulatory care strategies were ~30% compared to standard hospital care. The weighted average cost saving per episode of 'low-risk' febrile neutropenia using Strategy 1 (outpatient follow-up only) was 35% (range: 7-55%) and that for Strategy 2 (early discharge and outpatient follow-up) was 30% (range: 7-39%). Strategy 2 was more cost-effective than Strategy 1 and was deemed the more clinically favoured approach. CONCLUSION: This study outlines a cost structure for a safe and comprehensive ambulatory care program comprised of an early discharge pathway with outpatient follow-up, and promotes this as a cost effective approach to managing 'low-risk' febrile neutropenic patients.
