Abstract
BACKGROUND Balance training interventions with a gradual progression of difficulty and highly challenging tasks designed specifically for people with multiple sclerosis (MS) are rare. The objective was to adapt a balance training intervention originally developed for Parkinson's disease through a co-design process and then conduct a pilot trial in MS to evaluate the feasibility of a large, full-scale study. METHODS Twelve people with MS with mild to moderate overall MS-disability were included in this single-group feasibility trial. Participants received one-hour training sessions twice or three times weekly for 10 weeks. The assessment included tests of physical and cognitive functioning and patient-reported quality of life-related outcomes. Data on feasibility aspects were collected at baseline and follow-up assessments and three times during the intervention period to inform the recruitment process, as well as to monitor retention and inclusion rates, study procedures, intervention delivery, and dynamic changes in the selected potential outcome measures. Progression criteria were used to determine whether to proceed to a full-scale trial. Descriptive statistics were used to present the data. RESULTS Out of six progression criteria, only retention and attendance at training sessions were not met. Reasons reported for not completing the intervention period mainly depended on external circumstances beyond the control of the study. In contrast, study procedures, intervention delivery, and intervention content (progression, adjustment, and control of challenge level of exercises) were considered feasible for a future, full-scale trial. The Mini-BESTest, which was used for the assessment of balance control, was considered suitable as the primary outcome in a full-scale trial with no ceiling or floor effects. Further, the Mini-BESTest showed a positive trend in outcome response with a median difference of 3.5 points between baseline and follow-up assessments. The power calculation performed suggests a feasible number of participants for recruitment. CONCLUSIONS Overall trial aspects and intervention delivery were deemed feasible for a full-scale trial, but adjustments are needed to increase retention and attendance.

Abstract
Abstract
Background
When a family member is diagnosed with high-grade glioma, it not only affects the patient, but also the entire family. Due to an intense disease- and treatment trajectory and a complex symptom burden, patients often depend on support from their family caregivers. Family caregivers struggle to adjust to a change in family roles. Hence, proper information and supportive care are essential for patients and family caregivers to help them manage their changed life situations.
Material and Methods
This was a longitudinal multi-methods study applying qualitative interview data and quantitative survey data to explore and evaluate the programme. A multimodal rehabilitative palliative care programme was designed by a multidisciplinary cross-sectoral team of clinical specialists and researchers. The purpose was to provide patients and family caregivers with information and facilitate the exchange of perspectives and experiences among peers e.g. on daily living and family function. Additionally, to provide participants with strategies to manage this life transition
Results
Adult patients with high-grade glioma (n = 17) and their family caregivers (n = 16) completed a 4-day residential programme and a 2-day follow-up programme 3 months later. Qualitative data were collected during focus group interviews (n = 4) with patients and caregivers. Participants responded to self-developed questionnaires after each programme, scoring all sessions for relevance and satisfaction on a 5-point Likert scale (0, not relevant/satisfied; 5, very relevant/highly satisfied). Three themes emerged in the focus group interviews: 1) meeting peers strengthens social well-being, 2) the value of information and focusing on individual needs, and 3) accepting life as an unpredictable passage. The mean overall satisfaction score was 4.80 (standard deviation [SD], 0.55) for the initial 4-day programme and 4.28 (SD, 0.83) for the follow-up programme.
Conclusion
The multimodal rehabilitative palliative care programme addressed unmet patient and caregiver needs and may have the potential to enhance family function or coping mastery. The programme was feasible, and all sessions received high scores for satisfaction and relevance, as well as positive evaluations. Qualitative findings confirmed the value of individualized information and peer interactions. In particular, peer-to-peer interventions for family caregivers may address individual support needs, including sharing experiences and strengthening social well-being.

Abstract
BACKGROUND Long-term outcomes for Medicare beneficiaries hospitalised with transient ischaemic attack (TIA) and role of ABCD2 score in identifying high-risk individuals are not studied. METHODS We identified 40 825 Medicare beneficiaries hospitalised from 2011 to 2014 for a TIA to a Get With The Guidelines (GWTG)-Stroke hospital and classified them using ABCD2 score. Proportional hazards models were used to assess 1-year event rates of mortality and rehospitalisation (all-cause, ischaemic stroke, haemorrhagic stroke, myocardial infarction, and gastrointestinal and intracranial haemorrhage) for high-risk versus low-risk groups adjusted for patient and hospital characteristics. RESULTS Of the 40 825 patients, 35 118 (86%) were high risk (ABCD2 ≥4) and 5707 (14%) were low risk (ABCD2=0-3). Overall rate of mortality during 1-year follow-up after hospital discharge for the index TIA was 11.7%, 44.3% were rehospitalised for any reason and 3.6% were readmitted due to stroke. Patients with ABCD2 score ≥4 had higher mortality at 1 year than not (adjusted HR 1.18, 95% CI 1.07 to 1.30). Adjusted risks for ischaemic stroke, all-cause readmission and mortality/all-cause readmission at 1 year were also significantly higher for patients with ABCD2 score ≥4 vs 0-3. In contrast, haemorrhagic stroke, myocardial infarction, gastrointestinal bleeding and intracranial haemorrhage risk were not significantly different by ABCD2 score. CONCLUSIONS This study validates the use of ABCD2 score for long-term risk assessment after TIA in patients aged 65 years and older. Attentive efforts for community-based follow-up care after TIA are needed for ongoing prevention in Medicare beneficiaries who were hospitalised for TIA.

Abstract
Background A declining trend in mean cholesterol levels and smoking has been observed in high-income western countries during the last few decades, whereas obesity rates have increased. Simultaneously, mortality from coronary heart disease has decreased. The aim of the present study was to determine whether the trends in cardiovascular risk factors have continued in successive cohorts of middle-aged women over a period of 34 years. Methods Six population-based, cross-sectional samples of women (n = 2294) mean age: 49.8 years (range: 45–54), living in Gothenburg, Sweden, were investigated between 1980 and 2014. Results Body mass index (BMI) increased over time, with a mean BMI of 24.7 kg/m2 in 1980 to 25.7 kg/m2 in 2013–2014, corresponding to a weight gain of 4.5 kg, together with an increase in the proportion of obese individuals (BMI ≥ 30 kg/m2) from 10.4 to 16.6% (p = 0.0012). The proportion of smokers and women with hypertension decreased from 34.5 to 12.8% (p = 0.0006) and from 37.7 to 24.5% (p < 0.0001) respectively. Mean total serum cholesterol levels decreased from 6.23 (SD 1.09) mmol/L in 1980 to 5.43 (SD 0.98) mmol/L in 2013–2014 (p < 0.0001). Self-reported leisure time regular exercise increased from 7.8% in 1980 to 35.6% in 2013–2014 (p < 0.0001). For women born in 1963, the prevalence ratio of not having any of five major cardiovascular risk factors was 1.82 (95% confidence interval (CI) 1.38–2.41), compared with women born in 1925–1934. Conclusion The trend towards increasing obesity, more leisure-time physical activity and less smoking remains, while the decrease in serum cholesterol appears to have abated.

Abstract
Aims: Data on long-term healthcare costs of patients with peripheral artery disease (PAD) is limited, and the aim of this study was to investigate healthcare costs for PAD patients at a nationwide level. Methods and results: A cohort study including all incident patients diagnosed with PAD in the Swedish National Patient Register between 2006-2014, and linked to cause of death- and prescribed drug registers. Mean per-patient annual healthcare costs (2015 Euros [€]) (hospitalisations and out-patient visits) were divided into cardiovascular (CV), lower limb and non-CV related cost. Results were stratified by high and low CV risk. The study included 66,189 patients, with 221,953 observation-years. Mean total healthcare costs were €6,577, of which 26% was CV-related (€1,710), during the year prior to the PAD diagnosis. First year after PAD diagnosis, healthcare costs were €12,549, of which €3,824 (30%) was CV-related and €3,201 (26%) lower limb related. High-risk CV patients had a higher annual total healthcare and CV related costs compared to low risk CV patients during follow-up (€7,439 and €1,442 versus €4,063 and €838). Annual lower limb procedure costs were €728 in the PAD population, with lower limb revascularisations as key cost driver (€474). Conclusion: Non-CV related hospitalizations and outpatient visits were the largest cost contributors for PAD patients. There is a substantial increase in healthcare costs in the first year after being diagnosed with PAD, driven by PAD follow-up and lower limb related procedures. Among the CV-related costs, hospitalisations and outpatient visits related to PAD represented the largest costs.

Abstract
Objective To study age and sex specific prevalence of 30 symptoms in random samples from the general population and to analyze possible secular trends across time. Study population The study was based on data from eight on-going Swedish cohort studies, with baseline investigations performed between 1973 and 2003. Samples were drawn from the general population of the cities of Gothenburg and Eskilstuna, and of Uppsala County. Overall, 20,160 subjects were sampled, 14,470 (71.8%) responded, of whom 12.000 were unique subjects, and 2548 were part of more than one sample. Methods The Complaint score sub-scale of the Gothenburg Quality of Life instrument, listing 30 general symptoms was used. Responders were asked to indicate which symptoms they had experienced during the last three months. Results Women reported on average 7.8 symptoms, and men 5.3 (p<0.0001). Women reported higher prevalence than men for 24 of the 30 symptoms. In multivariate analyses four patterns of prevalence across age were identified in both men and women; increasing prevalence, decreasing, stable and biphasic prevalence. The symptoms in the various pattern groups differed somewhat between men and women. However, symptoms related to strain were prominent among symptoms decreasing with age. Moreover, there were secular trends. Across all symptoms reporting prevalence increased over time in men (p<0.001) as well as in women (p<0.0001). Conclusions Women reported higher total symptom prevalence than men. Symptoms related to health generally increased with age, while symptoms related to stress decreased markedly. Significant secular trends across time regarding symptom prevalence were found.

Abstract
OBJECTIVES Our purpose was to explore major vascular and bleeding outcomes in relation to risk and severity scores (ABCD2 or NIHSS) in patients with transient ischemic attack (TIA) or acute ischemic stroke (AIS). METHODS This nationwide observational study was based on data from 4 national registries. Outcomes were assessed by Kaplan-Meier and Cox regression analyses. RESULTS The total cohort comprised 21 268 patients (median age 73 years, 47.6% females). Based on ABCD2-score, the TIA-population (n = 10 174) was divided into low-risk (0-3 p, n = 3463) and high-risk (4-7 p, n = 6711). Based on NIHSS-score, the AIS-population (n = 11 454) was divided into minor (0-5 p, n = 8596), moderate (6-10 p, n = 1630) and severe (≥11 p, n = 1228). During follow-up (mean 1.7 years), the composite endpoint of stroke, myocardial infarction or death occurred in 3572 (16.5%) of all the patients, and major bleeding in 668 (3.1%) patients. Using low-risk TIA as reference, the adjusted hazard ratios (HR, 95% CI) of the composite endpoint were 1.41 (1.23-1.62) for high-risk TIA, 1.94 (1.70-2.22) for minor, 2.86 (2.45-3.34) for moderate and 4.18 (3.57-4.90) for severe stroke. When analyzed separately, the association with increased risk remained significant for stroke and death, but not for myocardial infarction. The HR of major bleeding were 1.31 (0.99-1.73) for high-risk TIA, 1.49 (1.13-1.95) for minor, 1.54 (1.08-2.21) for moderate and 2.10 (1.44-3.05) for severe stroke. CONCLUSIONS This study confirms the association between severity of the index ischemic stroke and risk of future major vascular and bleeding events, and highlights the increased risk also for patients with high-risk TIA.

AbstractThe purpose of this analysis was to assess potential predictors of intra-cranial bleeding (ICB) and gastrointestinal bleeding (GIB) in patients with symptomatic peripheral artery disease (PAD) in UK primary care. Patients with symptomatic PAD diagnosed from 2000 to 2010 were identified from The Health Improvement Network (THIN; N = 28,484). A nested case–control analysis, adjusted for potential confounders, was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for potential predictors of ICB or GIB. For GIB, follow-up was restricted to Hospital Episode Statistics-linked THIN practices. Median follow-up was 6 years. For ICB (153 cases), the OR (95% CI) was 3.85 (1.33–11.13) for previous ICB, 0.90 (0.61–1.34) for treated hypertension, 1.59 (0.65–3.87) for untreated hypertension and 1.38 (0.80–2.36) for current smoking. ORs for ICB were 0.78 (0.50–1.21), 0.40 (0.09–1.82) and 1.27 (0.47–3.47) with use of acetylsalicylic acid (ASA), clopidogrel and warfarin monotherapy, respectively, compared with non-use of such therapy. For GIB (506 cases), the OR was 1.40 (1.05–1.86) for peptic ulcer disease, 3.20 (1.81–5.64) for dual anti-platelet therapy use, 1.96 (1.46–2.64) for non-steroidal anti-inflammatory drug (NSAID) use and 1.01 (0.80–1.28) for proton pump inhibitor use. ORs for GIB were 1.78 (1.39–2.30), 2.03 (1.05–3.93) and 1.25 (0.72–2.16) with ASA, clopidogrel and warfarin monotherapy, respectively, compared with non-use. Previous ICB was a risk factor for ICB. Use of anti-platelet therapy or NSAIDs increased GIB risk. Identifying bleeding predictors could help optimize treatment strategies for patients with PAD.

Abstract
OBJECTIVE Acid suppression with histamine-2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs) is recommended for children with persistent gastroesophageal reflux disease symptoms. In this retrospective, observational postauthorization study, we aimed to assess and compare safety outcomes in pediatric first-time users of esomeprazole, other PPIs or H2RAs. METHODS Data on children (aged 0-18 years) first dispensed esomeprazole, other PPIs or H2RAs between September 2008 and August 2011 was obtained from the Dutch PHARMO Database Network. Hospitalizations for seven predefined safety outcomes were evaluated (maximum follow-up: 18 months). Rate ratios were calculated using Poisson regression adjusted for baseline imbalances. Discharge letters were reviewed for event occurrence confirmation. RESULTS Of 23,470 included children, 2820 (median age: 3 years) were prescribed esomeprazole, 13,818 (median age: 15 years) other PPIs and 6832 (median age: 5 years) H2RAs. In total, 504 (2%) children were hospitalized for 762 predefined events: gastroenteritis (246); convulsion/seizure (200); pneumonia (154); failure to thrive (119); acute interstitial nephritis (19); thrombocytopenia (23); and angioneurotic edema (1). Significant differences between cohorts were observed only for failure to thrive, with adjusted rate ratios (95% confidence interval) for esomeprazole of 6.1 (2.4-15.7) vs. other PPIs and 6.1 (2.9-12.8) vs. H2RAs among current users. Occurrence was confirmed for 74% of assessable events. Confirmation rates were highest for pneumonia (81%) and lowest for failure to thrive (40%). CONCLUSIONS Hospitalization rates for predefined outcomes were low and mostly similar in pediatric first-time users of PPIs and of H2RAs. TRIAL REGISTRATION NCT01338363.

Abstract
OBJECTIVES To assess time trends in symptomatic peripheral artery disease (PAD) incidence and prevalence, and secondary preventive therapy. DESIGN Cohort study using The Health Improvement Network. SETTING UK primary care. PARTICIPANTS Individuals aged 50-89 years identified annually between 2000 and 2014. Participants with symptomatic PAD were identified using Read codes. OUTCOME MEASURES Incidence and prevalence of symptomatic PAD from 2000 to 2014, overall and by sex and age. Proportion of patients prescribed secondary preventive therapy with acetylsalicylic acid (ASA), clopidogrel, an ACE inhibitor, an angiotensin receptor blocker (ARB) and/or a statin. RESULTS The incidence of symptomatic PAD per 10 000 person-years decreased over time, from 38.6 (men: 51.0; women: 28.7) in 2000 to 17.3 (men: 23.1; women: 12.4) in 2014. The prevalence of symptomatic PAD decreased from 3.4% (men: 4.5%; women: 2.5%) in 2000 to 2.4% (men: 3.1%; women: 1.7%) in 2014. Incidence and prevalence decreases were observed in all age groups. The proportions of patients prescribed ASA monotherapy, clopidogrel monotherapy and dual antiplatelet therapy in the 2 months after PAD diagnosis were 42.7%, 2.9% and 2.5%, respectively, during 2000-2003, and 44.7%, 11.0% and 5.2%, respectively, during 2012-2014. For ACE inhibitor/ARB therapy and statins, proportions in the 2 months after diagnosis were 30.2% and 31.2%, respectively, during 2000-2003, and 45.1% and 65.9%, respectively, during 2012-2014. CONCLUSION The incidence and prevalence of symptomatic PAD diagnosed in UK primary care are decreasing. A large proportion of the population with PAD in clinical practice does not receive guideline-recommended secondary prevention therapy.

Abstract
Background Long‐term disease progression after myocardial infarction (MI) is inadequately understood. We evaluated the pattern and angiographic properties (culprit lesion [CL]/non‐CL [NCL]) of recurrent MI (re‐MI) in a large real‐world patient population. Methods and Results Our observational study used prospectively collected data in 108 615 patients with first‐occurrence MI enrolled in the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence‐Based Care in Heart Disease Evaluated According to Recommended Therapies) between July 1, 2006 and November 29, 2014. During follow‐up (median, 3.2 years), recurrent hospitalization for MI occurred in 11 117 patients (10.2%). Of the patients who underwent coronary angiography for the index MI, a CL was identified in 44 332 patients. Of those patients, 3464 experienced an re‐MI; the infarct originated from the NCL in 1243 patients and from the CL in 655 patients. In total, 1566 re‐MIs were indeterminate events and could not be classified as NCL or CL re‐MIs. The risk of re‐MI within 8 years related to the NCL was 0.06 (95% confidence interval [CI], 0.05–0.06), compared with 0.03 (95% CI, 0.02–0.03) for the CL. There were no large differences in baseline characteristics of patients with subsequent NCL versus CL re‐MIs. Independent predictors of NCL versus CL re‐ MI were multivessel disease (odds ratio, 2.29; 95% CI, 1.87–2.82), male sex (odds ratio, 1.36; 95% CI, 1.09–1.71), and a prolonged time between the index and re‐MI (odds ratio, 1.16; 95% CI, 1.10–1.22). Conclusions In a large cohort of patients with first‐occurrence MI undergoing percutaneous coronary intervention, the risk of re‐MI originating from a previously untreated lesion was twice higher than the risk of lesions originating from a previously stented lesion.

Abstract
BACKGROUND Little is known about the use of acid-suppressing treatments and related safety events in children. OBJECTIVE This study compared patient characteristics and safety outcomes among children prescribed acid-suppressing drugs for the first time. METHODS The Health Improvement Network was used to determine the characteristics of children prescribed a proton pump inhibitor (PPI; esomeprazole or another PPI) or a histamine-2 receptor antagonist (H2RA) by UK primary care physicians between October 2009 and September 2012. Pre-defined safety outcomes were compared among the treatment groups in up to 18 months of follow-up. RESULTS The cohorts comprised 8,172 patients on PPIs (including 24 patients on esomeprazole) and 7,905 on H2RAs. The baseline characteristics were similar between cohorts, although the children in the PPI cohorts tended to be older. No safety outcomes occurred in the esomeprazole cohort. In the other-PPIs cohort, 92 safety outcomes occurred, most commonly gastroenteritis (n = 36; 39.1%). In the H2RAs cohort, 193 safety outcomes occurred, most commonly gastroenteritis (n = 62; 32.1%). The incidence of most safety outcomes was higher in the H2RAs cohort than in the other-PPIs cohort, including failure to thrive (3.11 [95% confidence interval (CI) = 2.25-4.28] vs 0.49 per 1,000 person-years [95% CI = 0.22-1.07]) and gastroenteritis (5.27 [95% CI = 4.11-6.75] vs 3.04 per 1,000 person-years [95% CI = 2.20-4.20]). CONCLUSION Esomeprazole is rarely prescribed to children when they first require acid-suppressing medication, compared with other PPIs/H2RAs. Overall, more safety outcomes occurred in the H2RAs cohort than in the PPI cohorts.

Abstract
SummarySome pharmacokinetic studies have reported that proton pump inhibitors (PPIs) reduce the activity of clopidogrel, but the results of studies assessing clinical outcomes in patients receiving both drugs are inconsistent. We have therefore carried out a population-based cohort study with nested case–control analysis, in order to evaluate changes in the risk of cardiovascular and peptic ulcer bleeding (PUB) events associated with PPI use in patients receiving clopidogrel. A total of 42,542 patients aged 50–84 years in 2000–2007 who survived an acute coronary event were identified in two UK-based primary care databases (The Health Improvement Network and the General Practice Research Database). Individuals were followed up to identify incident cases of non-fatal myocardial infarction/coronary death (n = 2,546) and PUB (n = 194). Controls were frequency matched to cases by age, sex and calendar year. Compared with PPI non-use, current continuous PPI use was not associated with a significant change in risk of non-fatal myocardial infarction/coronary death among current continuous users of clopidogrel monotherapy (relative risk [RR], 1.06; 95% confidence interval [95% CI], 0.47 to 2.36) or dual antiplatelet therapy (DAT; RR, 0.80; 95% CI, 0.47 to 1.37) who initiated their antiplatelet therapy shortly after their coronary event. Among patients prescribed DAT at the start date, the RR of PUB events associated with current PPI use initiated at the start date was 0.66 (95% CI, 0.27 to 1.60).

Abstract
SummaryThis study evaluated the risk of cardiovascular events associated with the use of proton pump inhibitors (PPIs) in new users of acetylsalicylic acid (ASA) for the secondary prevention of cardiovascular events. Two cohorts of patients aged 50–84 years were identified from UK primary care databases: individuals with a first prescription for ASA (75−300 mg/day) for secondary prevention of cardiovascular events (n = 39,513; CVD cohort) or with a record of hospitalisation for an acute coronary event (n = 42,542; ACS cohort) in 2000–2007. Cases of nonfatal myocardial infarction (MI) and coronary death were identified: 1,222 in the CVD cohort and 604 among new users of ASA in the ACS cohort. A nested case–control analysis estimated the relative risk (RR) of non-fatal MI or coronary death associated with use vs non-use of PPI therapy. Current continuous use of PPI therapy was not associated with a significant increase in RR overall: in the CVD cohort (RR = 1.14 [95% confidence interval = 0.91−1.43]); in the ACS cohort (0.88 [0.66−1.18]); or among current continuous users of ASA as antiplatelet monotherapy (CVD cohort: 1.15 [0.80−1.66]; ACS cohort: 0.73 [0.43−1.23]; pooled analysis of both cohorts: 0.96 [0.62−1.48]). In conclusion, among first-time users of ASA for the secondary prevention of cardiovascular events, PPI use was not shown to be associated with an increased risk of non-fatal MI or coronary death.

Abstract
AIMS Heterozygous mutations in hepatocyte nuclear factor-1A (HNF1A) cause maturity-onset diabetes of the young type 3 (MODY3). Our aim was to compare two families with suspected dominantly inherited diabetes and a new HNF1A variant of unknown clinical significance. METHODS The HNF1A gene was sequenced in two independently recruited families from the Norwegian MODY Registry. Both familes were phenotyped clinically and biochemically. Microsatellite markers around and within the HNF1A locus were used for haplotyping. Chromosomal linkage analysis was performed in one family, and whole-exome sequencing was undertaken in two affected family members from each family. Transactivation activity, DNA binding and nuclear localization of wild type and mutant HNF-1A were assessed. RESULTS The novel HNF1A variant c.539C>T (p.Ala180Val) was found in both families. The variant fully co-segregated with diabetes in one family. In the other family, two subjects with diabetes mellitus and one with normal glucose levels were homozygous variant carriers. Chromosomal linkage of diabetes to the HNF1A locus or to other genomic regions could not be established. The protein functional studies did not reveal significant differences between wild type and variant HNF-1A. In each family, whole-exome sequencing failed to identify any other variant that could explain the disease. CONCLUSIONS The HNF1A variant p.Ala180Val does not seem to cause MODY3, although it may confer risk for type 2 diabetes mellitus. Our data demonstrate challenges in causality evaluation of rare variants detected in known diabetes genes.

Abstract
OBJECTIVE The associations between duration of second stage of labor, pushing time and risk of adverse neonatal outcomes are not fully established. Therefore, we aimed to examine such relationships. STUDY DESIGN A population-based cohort study including 42 539 nulliparous women with singleton infants born in cephalic presentation at ⩾37 gestational weeks, using the Stockholm-Gotland Obstetric Cohort, Sweden, and the Swedish Neonatal Quality Register, 2008 to 2013. Poisson regression was used to analyze estimated adjusted relative risks (RRs), with 95% confidence intervals (CIs). Outcome measures were umbilical artery acidosis (pH <7.05 and base excess <-12), birth asphyxia-related complications (including any of the following conditions: hypoxic ischemic encephalopathy, hypothermia treatment, neonatal seizures, meconium aspiration syndrome or advanced resuscitation after birth) and admission to neonatal intensive care unit (NICU). RESULTS Overall rates of umbilical artery acidosis, birth asphyxia-related complications and admission to NICU were 1.08, 0.63 and 6.42%, respectively. Rate of birth asphyxia-related complications gradually increased with duration of second stage: from 0.42% at <1 h to 1.29% at ≥4 h (adjusted RR 2.46 (95% CI 1.66 to 3.66)). For admission to NICU, corresponding rates were 4.97 and 9.45%, and adjusted RR (95% CI) was 1.80 (95% CI 1.58 to 2.04). Compared with duration of pushing <15 min, a duration of pushing ⩾60 min increased rates of acidosis from 0.57 to 1.69% (adjusted RR 2.55 (95% CI 1.51 to 4.30)). CONCLUSION Prolonged durations of second stage of labor and pushing are associated with increased RRs of adverse neonatal outcomes. Clinical assessment of fetal well-being is essential when durations of second stage and pushing increases.

Abstract
OBJECTIVE The objective of the study was to examine normal variations of umbilical cord arterial pH by gestational age (GA). STUDY DESIGN Population-based cohort study of 46 199 infants born from 2008 to 2014 in Stockholm, Sweden, with GA 28 to 42 weeks, Apgar score ⩾7 at 5 min, non-instrumental vaginal delivery, and birth weight for GA⩾3rd and ⩽97th percentile. Quantile regression was used to investigate the associations between GA and infant sex, and pH. RESULTS The mean umbilical cord arterial pH (s.d.) was 7.29 (0.10), 7.27 (0.07), 7.25 (0.07) and 7.23 (0.07) among infants born at 28 to 31, 32 to 36, 37 to 41 and 42 weeks, respectively. Arterial pH decreased linearly with increasing GA, and female infants had higher pH than male infants (P<0.001). CONCLUSION Umbilical cord arterial pH varied in a linear fashion by GA and was influenced by infant sex. The provided reference curve taking GA into account may yield a more accurate definition of acidosis at birth.

Abstract
OBJECTIVES The pandemic spread of multidrug-resistant (MDR) bacteria poses a threat to healthcare worldwide, with highest prevalence in indigent regions of the (sub)tropics. As hospitalization constitutes a major risk factor for colonization, infection control management in low-prevalence countries urgently needs background data on patients hospitalized abroad. METHODS We collected data on 1122 patients who, after hospitalization abroad, were treated at the Helsinki University Hospital between 2010 and 2013. They were screened for methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE), vancomycin-resistant enterococci, carbapenemase-producing Enterobacteriaceae (CPE), multiresistant Pseudomonas aeruginosa and multiresistant Acinetobacter baumannii. Risk factors for colonization were explored by multivariate analysis. RESULTS MDR colonization rates were higher for those hospitalized in the (sub)tropics (55%; 208/377) compared with temperate zones (17%; 125/745). For ESBL-PE the percentages were 50% (190/377) versus 12% (92/745), CPE 3.2% (12/377) versus 0.4% (3/745) and MRSA 6.6% (25/377) versus 2.4% (18/745). Colonization rates proved highest in those returning from South Asia (77.6%; 38/49), followed by those having visited Latin America (60%; 9/16), Africa (60%; 15/25) and East and Southeast Asia (52.5%; 94/179). Destination, interhospital transfer, short time interval to hospitalization, young age, surgical intervention, residence abroad, visiting friends and relatives, and antimicrobial use proved independent risk factors for colonization. CONCLUSIONS Post-hospitalization colonization rates proved higher in the (sub)tropics than elsewhere; 11% (38/333) of carriers developed an MDR infection. We identified several independent risk factors for contracting MDR bacteria. The data provide a basis for infection control guidelines in low-prevalence countries.

Abstract
Background Most studies of outcomes after myocardial infarction (MI) focus on the acute phase after the index event. We assessed mortality and morbidity trends after the first year in survivors of acute MI, by conducting a systematic literature review. Methods Literature searches were conducted in Embase, MEDLINE, and the Cochrane Database of Systematic Reviews to identify epidemiological studies of long-term (>10 years) mortality and morbidity trends in individuals who had experienced an acute MI more than 1 year previously. Results Thirteen articles met the inclusion criteria. Secular trends showed a consistent decrease in mortality and morbidity after acute MI from early to more recent study periods. The relative risk for all-cause death and cardiovascular outcomes (recurrent MI, cardiovascular death) was at least 30% higher than that in a general reference population at both 1–3 years and 3–5 years after MI. Risk factors leading to worse outcomes after MI included comorbid diabetes, hypertension and peripheral artery disease, older age, reduced renal function, and history of stroke. Conclusions There have been consistent improvements in secular trends for long-term survival and cardiovascular outcomes after MI. However, MI survivors remain at higher risk than the general population, particularly when additional risk factors such as diabetes, hypertension, or older age are present.

Abstract
Dermal exposure to low volatile organophosphorus compounds (OPC) may lead to penetration through the skin and uptake in the blood circulation. Skin decontamination of toxic OPCs, such as pesticides and chemical warfare nerve agents, might therefore be crucial for mitigating the systemic toxicity following dermal exposure. Reactive skin decontamination lotion (RSDL) has been shown to reduce toxic effects in animals dermally exposed to the nerve agent VX. In the present study, an in vitro flow-through diffusion cell was utilized to evaluate the efficacy of RSDL for decontamination of VX exposed to human epidermis. In particular, the impact of timing in the initiation of decontamination and agent dilution in water was studied. The impact of the lipophilic properties of VX in the RSDL decontamination was additionally addressed by comparing chemical degradation in RSDL and decontamination efficacy between the VX and the hydrophilic OPC triethyl phosphonoacetate (TEPA). The epidermal membrane was exposed to 20, 75 or 90% OPC diluted in deionized water and the decontamination was initiated 5, 10, 30, 60 or 120min post-exposure. Early decontamination of VX with RSDL, initiated 5-10min after skin exposure, was very effective. Delayed decontamination initiated 30-60min post-exposure was less effective but still the amount of penetrated agent was significantly reduced, while further delayed start of decontamination to 120min resulted in very low efficacy. Comparing RSDL decontamination of VX with that of TEPA showed that the decontamination efficacy at high agent concentrations was higher for VX. The degradation mechanism of VX and TEPA during decontamination was dissected by 31P NMR spectroscopy of the OPCs following reactions with RSDL and its three nucleophile components. The degradation rate was clearly associated with the high pH of the specific solution investigated; i.e. increased pH resulted in a more rapid degradation. In addition, the solubility of the OPC in RSDL also influenced the degradation rate since the degradation of VX was significantly faster when the NMR analysis was performed in the organic solvent acetonitrile compared to water. In conclusion, we have applied the in vitro flow-through diffusion cell for evaluation of skin decontamination procedures of human epidermis exposed to OPCs. It was demonstrated that early decontamination is crucial for efficient mitigation of epidermal penetration of VX and that almost complete removal of the nerve agent from the skin surface is possible. Our data also indicate that the pH of RSDL together with the solubility of OPC in RSDL are of primary importance for the decontamination efficacy.

Abstract
OBJECTIVES Longitudinal data are limited regarding outcomes and costs beyond 1 year after acute myocardial infarction (MI) among elderly (≥65 years old) US patients. This study examined long-term outcomes and healthcare costs among elderly MI survivors. METHODS Retrospective analysis of 2002-2009 Medicare healthcare claims (5% random sample). Patients were ≥65 years old and survived ≥1 year without recurrent MI after MI hospitalization. Mortality, incidence of hospitalizations for stroke, major bleeding, MI, a composite endpoint (death, MI, or stroke), and nonpharmacy healthcare costs were determined. RESULTS Eligible patients included 16 244 STEMI, 34 576 NSTEMI, and 3109 unspecified MI. NSTEMI and unspecified MI patients had significantly higher prevalence of comorbidities than STEMI patients, except for hypertension and dyslipidemia. MI incidence declined 36% over the follow-up (3.82/100 person-years [PY] to 2.45/100 PY). Mortality, stroke, and bleeding decreased until the third year of follow-up and then increased. NSTEMI and unspecified MI patients had a significantly higher incidence of death, MI, the composite, and bleeding than STEMI patients throughout follow-up. All-cause inpatient costs during follow-up were 2.6- and 1.9-fold higher than baseline for STEMI and NSTEMI, respectively; cardiovascular-related inpatient costs were 3.5- and 2.2-fold higher, respectively. CONCLUSIONS Risks of mortality and cardiovascular events remain high in a Medicare population surviving >1 year after a MI. Continuing healthcare costs are doubled over pre-MI levels up to 5 years after an MI. Secondary prevention measures beyond the acute post-MI period may be indicated to reduce risk and cost in this chronic disease phase.

Abstract
This study sought to investigate the feasibility of the Free Recall and Recognition Test (FRRT) as a practical screening tool for cognitive impairment in multiple sclerosis (MS). Persons with MS (n =227) were consecutively recruited and assessed with four cognitive tests; FRRT, Symbol Digit Modalities Test (SDMT), Paced Auditory Serial Addition Test (PASAT), and the Mini-Mental State Examination (MMSE). Disease severity was assessed by the Expanded Disability Status Scale (EDSS). The FRRT, which was completed by 99% of the cohort in approximately 5 minutes per assessment, correlated significantly with the other cognitive tests, as well as with the disease severity rating. A cut-off of 4 for the FRRT recall rendered 90% sensitivity and 25% specificity, and a cut-off of 4.2 for the FRRT recognition resulted in 70% sensitivity and 51% specificity. We conclude that the FRRT proved feasible as a practical screening tool for cognitive impairment in MS within a clinical setting. Multiple Sclerosis 2007; 13: 272–274. http://msj.sagepub.com

Abstract
AIM This study compared obstetric units practicing routine or selective umbilical cord blood gas analysis, with respect to the risk of missing samples in high-risk deliveries and in infants with birth asphyxia. METHODS This was a Swedish population-based cohort study that used register data for 155 235 deliveries of live singleton infants between 2008 and 2014. Risk ratios and 95% confidence intervals were calculated to estimate the association between routine and selective umbilical cord blood gas sampling strategies and the risk of missing samples. RESULTS Selective sampling increased the risk ratios when routine sampling was used as the reference, with a value of 1.0, and these were significant in high-risk deliveries and birth asphyxia. The risk ratios for selective sampling were large-for-gestational age (9.07), preterm delivery at up to 36 weeks of gestation (8.24), small-for-gestational age (7.94), two or more foetal scalp blood samples (5.96), an Apgar score of less than seven at one minute (2.36), emergency Caesarean section (1.67) and instrumental vaginal delivery (1.24). CONCLUSION Compared with routine sampling, selective umbilical cord blood gas sampling significantly increased the risks of missing samples in high-risk deliveries and in infants with birth asphyxia.

Abstract
OBJECTIVES Previous, large, prescription-event monitoring studies in patients receiving PPI therapy recorded instances of convulsion or seizure. The objective of this study was to quantify the relative risk of seizure associated with the use of proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) in a general population, overall and stratified by epilepsy status, and to determine the effects of demographics and comorbidities. METHODS In this observational study (NCT01744301), patients aged 20-84years in the study period from 1 January 2005 to 31 December 2011 were identified from The Health Improvement Network. In a nested case-control analysis, 8605 patients with seizure were matched to 40000 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression. RESULTS After adjustment, there were no associations between current PPI use and seizure risk in the overall population (OR: 1.05; 95% CI: 0.87-1.27), the subcohort with epilepsy (OR: 0.87; 95% CI: 0.49-1.53), and the subcohort without epilepsy (OR: 1.05; 95% CI: 0.87-1.28). There were no associations between current H2RA use and seizure risk in the overall population (OR: 1.16; 95% CI: 0.62-2.18) and the subcohort without epilepsy (OR: 1.02; 95% CI: 0.51-2.01). Seizures were less frequent in women than in men. Dementia/psychosis, anxiety, depression, and use of anxiolytics, antidepressants, and paracetamol were associated with an increased seizure risk. CONCLUSIONS Our study revealed that the use of PPIs and the use of H2RAs were not associated with an increased risk of seizures in the overall population or in the cohorts stratified by epilepsy status.

Abstract
BACKGROUND Although obesity is an important determinant of an unfavourable risk factor pattern reported associations between cardiovascular disease and obesity in women have been remarkably inconsistent. DESIGN Longitudinal observational population study. METHODS 1408 Göteborg women without prior cardiovascular disease aged 39 to 65 years at baseline were examined with respect to cardiovascular risk factors, including body mass index (BMI), in 1979 to 1981. Quartiles of BMI were formed of <22 (reference), 22 to 24, 24 to 27, and >27 kg/m(-2). Follow-up was conducted by use of the Swedish patient and cause-specific death registers. RESULTS All trends with respect to incident coronary heart disease (CHD--myocardial infarction or revascularization), stroke and all cardiovascular disease were positive and significant (P<0.05). No significant increase in risk was noted in women with BMI 22-24, compared with women below 22. After adjustment for smoking, women with BMI 24 to 27 had a doubled risk of CHD [hazard ratio(HR) 2.41 (1.06-5.50)] and of any cardiovascular disease [HR 1.89 (1.05-3.37)] whereas the increase in stroke risk was non-significant [HR 1.80 (0.81-4.01)]. Hazard ratios in the heaviest women, with BMI >27, were 3.75 (1.68-8.37) for CHD, 2.84 (1.32-6.12) for stroke, and 2.98 (1.70-5.21) for any cardiovascular disease, after adjustment for smoking. After further adjustment for other cardiovascular risk factors, all trends became non-significant. However, women with BMI >27 still displayed a statistically independent association with respect to coronary disease [adjusted HR 2.67 (1.10-6.47)] and all cardiovascular disease [HR 2.23 (1.23-4.04)], but not stroke [HR 2.08 (0.94-4.61)]. CONCLUSION The influence of BMI on cardiovascular disease in women may be greater than previously thought and, although to a great extent explained by the influence of obesity on other risk factors, associated with adverse outcomes already at moderately increased body weight.

Abstract
AIMS To assess the international validity of using hospital record data to compare long-term outcomes in heart attack survivors. METHODS AND RESULTS We used samples of national, ongoing, unselected record sources to assess three outcomes: cause death; a composite of myocardial infarction (MI), stroke, and all-cause death; and hospitalized bleeding. Patients aged 65 years and older entered the study 1 year following the most recent discharge for acute MI in 2002-11 [n = 54 841 (Sweden), 53 909 (USA), 4653 (England), and 961 (France)]. Across each of the four countries, we found consistent associations with 12 baseline prognostic factors and each of the three outcomes. In each country, we observed high 3-year crude cumulative risks of all-cause death (from 19.6% [England] to 30.2% [USA]); the composite of MI, stroke, or death [from 26.0% (France) to 36.2% (USA)]; and hospitalized bleeding [from 3.1% (France) to 5.3% (USA)]. After adjustments for baseline risk factors, risks were similar across all countries [relative risks (RRs) compared with Sweden not statistically significant], but higher in the USA for all-cause death [RR USA vs. Sweden, 1.14 (95% confidence interval 1.04-1.26)] and hospitalized bleeding [RR USA vs. Sweden, 1.54 (1.21-1.96)]. CONCLUSION The validity of using hospital record data is supported by the consistency of estimates across four countries of a high adjusted risk of death, further MI, and stroke in the chronic phase after MI. The possibility that adjusted risks of mortality and bleeding are higher in the USA warrants further study.

Abstract
BACKGROUND Methylenetetrahydrofolate dehydrogenase (MTHFD1) catalyzes three sequential reactions that metabolize derivatives of tetrahydrofolate (THF) in folate-dependent one-carbon metabolism. Impaired MTHFD1 flux has been linked to disturbed lipid metabolism and oxidative stress. However, limited information is available on its relation to the development of atherothrombotic cardiovascular disease. METHODS AND RESULTS We explored the association between a MTHFD1 polymorphism (rs1076991 C > T) and acute myocardial infarction (AMI), and potential effect modifications by folic acid/B12 and/or vitamin B6 treatment in suspected stable angina pectoris patients (n = 2381) participating in the randomized Western Norway B Vitamin Intervention Trial (WENBIT). During the median follow-up of 4.9 years 204 participants (8.6%) suffered an AMI. After adjusting for established CVD risk factors, the MTHFD1 polymorphism was significantly associated with AMI (HR: 1.49; 95% CI, 1.23-1.81). A similar association was observed among patients allocated to treatment with vitamin B6 alone (HR: 1.53; 95% CI, 1.01-2.31), and an even stronger relationship was seen in patients treated with both vitamin B6 and folic acid/B12 (HR: 2.35; 95% CI, 1.55-3.57). However, no risk association between the MTHFD1 polymorphism and AMI was seen in patients treated with placebo (HR: 1.29; 95% CI, 0.86-1.93) or folic acid/B12 (1.17; 95% CI, 0.83-1.65). CONCLUSION A common and functional MTHFD1 polymorphism is associated with increased risk of AMI, although the risk seems to be dependent on specific B vitamin treatment. Further studies are warranted to elucidate the possible mechanisms, also in order to explore potential effect modifications by nutritional factors.

Abstract
OBJECTIVE To investigate how people with multiple sclerosis (MS) experience their participation in individual, face-to-face cognitive behavioural therapy (CBT) aimed at alleviating depressive symptoms. METHOD Semistructured interviews with 12 participants were conducted after CBT and analyzed using qualitative content analysis. RESULTS Two main themes emerged: CBT as a demanding process and confronting everyday life after CBT with self-knowledge and well-being. The participants had gained strategies for handling feelings of depression and anxiety. The therapist was considered important for guiding them through the demanding therapy. CONCLUSION It is important to inform the participants of what CBT entails so that they are mentally prepared for the demanding process and can make the necessary adjustments in their daily life. Knowledge of MS among the therapists as well as collaboration with the multidisciplinary MS care may facilitate participation in CBT.

Abstract
It has been suggested that the prevalence of Helicobacter pylori infection has stabilized in the USA and is decreasing in China. We conducted a systematic literature analysis to test this hypothesis. PubMed and Embase searches were conducted up to 19 January 2015. Trends in the prevalence of H. pylori infection over time were assessed by regression analysis using Microsoft Excel. Overall, 25 Chinese studies (contributing 28 datasets) and 11 US studies (contributing 11 datasets) were included. There was a significant decrease over time in the H. pylori infection prevalence for the Chinese studies overall (p = 0.00018) and when studies were limited to those that used serum immunoglobulin G (IgG) assays to detect H. pylori infection (p = 0.014; 20 datasets). The weighted mean prevalence of H. pylori infection was 66 % for rural Chinese populations and 47 % for urban Chinese populations. There was a significant trend towards a decreasing prevalence of H. pylori infection for studies that included only urban populations (p = 0.04; 9 datasets). This trend was no longer statistically significant when these studies were further restricted to those that used serum IgG assays to detect H. pylori infection, although this may have been because of low statistical power due to the small number of datasets available for this analysis (p = 0.28; 6 datasets). There were no significant trends in terms of changes in the prevalence of H. pylori infection over time for studies conducted in the USA. In conclusion, the prevalence of H. pylori infection is most likely decreasing in China, due to a combination of increasing urbanization, which we found to be associated with lower H. pylori infection rates, and possibly also decreasing rates of H. pylori infection within urban populations. This will probably result in a gradual decrease in peptic ulcer and gastric cancer rates in China over time.

Abstract
Introduction:
Patients experiencing a mild ischemic stroke (MIS) or transient ischemic attack (TIA) are at high risk of further events in the next 90 days. A good understanding of the unmet medical needs in these patients is required to develop evidenced-based treatment options that may improve post-stroke outcomes.
Aims:
This systematic literature review aimed to assess 90-day outcomes in patients following an MIS in routine clinical practice.
Methods:
Ovid MEDLINE and Embase were searched using terms relating to disease, severity and outcomes. Key inclusion criteria were: ≥ 100 patients with MIS (NIHSS score ≤ 5); 90-day outcomes reported; and non-interventional study design.
Results:
In total, 6510 records were identified. Of these, 18 articles reporting outcomes from 16 studies were included in the review. Stroke recurrence at 90 days, reported by 7 studies, varied widely (0.9-24.6%; Table); there were differences in study size, recurrence definition and time to presentation. Mortality at 90 days was 0.2-5.1% (13 studies), with a trend towards higher mortality in studies using higher NIHSS cut-off values to define MIS. Most patients had modified Rankin Scale scores of 0-1 (6 studies) or 0-2 (5 studies) at 90 days.
Conclusions:
The rates of 90-day stroke recurrence in patients following an MIS identified in this comprehensive literature review suggest there is a need for improvement in current clinical practice. However, identified studies reporting stroke recurrence had varied methodologies. Further standardized studies in these patients may be needed to better understand stroke recurrence, severity and mortality.

Abstract
BACKGROUND Some research has suggested a potential link between prenatal exposure to proton pump inhibitors (PPIs) or H2 -receptor antagonists (H2 RAs) and the development of childhood asthma. AIM To quantify the relative risk of asthma in children who experienced pre-natal exposure to PPIs and/or H2 RAs, adjusting for potential confounders. METHODS In this observational cohort study (NCT01787435), women aged 18-45 years with completed pregnancies between January 1996 and December 2010 were identified from The Health Improvement Network in the United Kingdom, and were linked to infants. Hazard ratios (HRs) were estimated using Cox proportional hazard models. RESULTS Our analysis identified 2371 prenatally exposed and 7745 unexposed infants. The incidence of asthma (per 1000 person-years) was 19.52 in the unexposed cohort, 23.88 in the PPI cohort and 32.16 in the H2 RA cohort. After adjusting for maternal healthcare utilisation during the year before pregnancy, the HR for asthma in infants whose mothers received prescriptions at any time during pregnancy was 1.12 (95% confidence interval: 0.88-1.44) for PPIs and 1.43 (1.20-1.70) for H2 RAs, when compared with unexposed infants. With further adjustment for maternal comorbidities and other medications, the HR for asthma was 1.03 (0.76-1.40) for PPIs and 1.32 (1.05-1.64) for H2 RAs. CONCLUSIONS Our analysis showed no association between prenatal exposure to PPIs and asthma in childhood after adjusting for confounders. The association found for H2 RAs may be explained largely by underlying environmental or genetic factors, as suggested by reductions in hazard ratio estimates following adjustment for maternal comorbidities.

Abstract
BACKGROUND The independent impact of respiratory rate on ventilator-induced lung injury has not been fully elucidated. The aim of this study was to investigate the effects of two clinically relevant respiratory rates on early ventilator-induced lung injury evolution and lung edema during the protective ARDSNet strategy. We hypothesized that the use of a higher respiratory rate during a protective ARDSNet ventilation strategy increases lung inflammation and, in addition, lung edema associated to strain-induced activation of transforming growth factor beta (TGF-β) in the lung epithelium. METHODS Twelve healthy piglets were submitted to a two-hit lung injury model and randomized into two groups: LRR (20 breaths/min) and HRR (40 breaths/min). They were mechanically ventilated during 6 h according to the ARDSNet strategy. We assessed respiratory mechanics, hemodynamics, and extravascular lung water (EVLW). At the end of the experiment, the lungs were excised and wet/dry ratio, TGF-β pathway markers, regional histology, and cytokines were evaluated. RESULTS No differences in oxygenation, PaCO2 levels, systemic and pulmonary arterial pressures were observed during the study. Respiratory system compliance and mean airway pressure were lower in LRR group. A decrease in EVLW over time occurred only in the LRR group (P < 0.05). Wet/dry ratio was higher in the HRR group (P < 0.05), as well as TGF-β pathway activation. Histological findings suggestive of inflammation and inflammatory tissue cytokines were higher in LRR. CONCLUSION HRR was associated with more pulmonary edema and higher activation of the TGF-β pathway. In contrast with our hypothesis, HRR was associated with less lung inflammation.

Association between low-dose acetylsalicylic acid reinitiation and the risk of myocardial infarction or coronary heart disease death. Eur J Prev Cardiol 2015; 23:1029-36.

Abstract
BACKGROUND In secondary cardiovascular prevention, discontinuation of acetylsalicylic acid (ASA) is associated with an increased risk of cardiovascular events. This study assessed the impact of ASA reinitiation on the risk of myocardial infarction and coronary heart disease death. METHODS Patients prescribed ASA for secondary cardiovascular prevention and who had had a period of ASA discontinuation of ≥90 days in 2000-2007 were identified from The Health Improvement Network (N = 10,453). Incidence of myocardial infarction/coronary heart disease death was calculated. Survival analyses using adjusted Cox proportional hazard models were performed to calculate hazard ratios and 95% confidence intervals for the risk of myocardial infarction/coronary heart disease death associated with ASA use patterns after the initial period of discontinuation. Individuals who were prescribed ASA during follow-up were considered reinitiators. RESULTS The incidence of myocardial infarction/coronary heart disease death was 8.90 cases per 1000 person-years. Risk of myocardial infarction/coronary heart disease death was similar for current ASA users, who had been continuously exposed since reinitiation, and patients who had not reinitiated ASA (hazard ratio 1.27, 95% confidence interval 0.93-1.73). Among reinitiators, an additional period of ASA discontinuation was associated with increased risk of myocardial infarction/coronary heart disease death compared with no reinitiation (current users: hazard ratio 1.46, 95% confidence interval 1.13-1.90; noncurrent users: hazard ratio 1.70, 95% confidence interval 1.31-2.21). CONCLUSIONS ASA reinitiation was not associated with a decreased risk of myocardial infarction/coronary heart disease death. This may be explained by confounding by indication/comorbidity, whereby higher-risk patients are more likely to reinitiate therapy. An additional period of ASA discontinuation among reinitiators was associated with an increased risk of myocardial infarction/coronary heart disease death.
