Empagliflozin is associated with lower cardiovascular risk compared with dipeptidyl peptidase-4 inhibitors in adults with and without cardiovascular disease: EMPagliflozin compaRative effectIveness and SafEty (EMPRISE) study results from Europe and Asia.

BACKGROUND: Studies that have reported lower risk for cardiovascular outcomes in users of Sodium-Glucose Cotransporter-2 Inhibitors (SGLT-2i) are limited by residual cofounding and lack of information on prior cardiovascular disease (CVD). This study compared risk of cardiovascular events in patients within routine care settings in Europe and Asia with type 2 diabetes (T2D) initiating empagliflozin compared to dipeptidyl peptidase-4 inhibitors (DPP-4i) stratified by pre-existing CVD and history of heart failure (HF). METHODS AND RESULTS: Adults initiating empagliflozin and DPP-4i in 2014-2018/19 from 11 countries in Europe and Asia were compared using propensity score matching and Cox proportional hazards regression to assess differences in rates of primary outcomes: hospitalisation for heart failure (HHF), myocardial infarction (MI), stroke; and secondary outcomes: cardiovascular mortality (CVM), coronary revascularisation procedure, composite outcome including HHF or CVM, and 3-point major adverse cardiovascular events (MACE: MI, stroke and CVM). Country-specific results were meta-analysed and pooled hazard ratios (HR) with 95% confidence intervals (CI) from random-effects models are presented. In total, 85,244 empagliflozin/DPP4i PS-matched patient pairs were included with overall mean follow-up of 0.7 years. Among those with pre-existing CVD, lower risk was observed for HHF (HR 0.74; 95% CI 0.64-0.86), CVM (HR 0.55; 95% CI 0.38-0.80), HHF or CVM (HR 0.57; 95% CI 0.48-0.67) and stroke (HR 0.79; 95% CI 0.67-0.94) in patients initiating empagliflozin vs DPP-4i. Similar patterns were observed among patients without pre-existing CVD and those with and without pre-existing HF. CONCLUSION: These results from diverse patient populations in routine care settings across Europe and Asia demonstrate that initiation of empagliflozin compared to DPP-4i results in favourable cardioprotective effects regardless of pre-existing CVD or HF status.

Risk of cardiovascular events after an exacerbation of chronic obstructive pulmonary disease: results from the EXACOS-CV cohort study using the PHARMO Data Network in the Netherlands.

BACKGROUND: People living with chronic obstructive pulmonary disease (COPD) have an increased risk of experiencing cardiovascular (CV) events, particularly after an exacerbation. Such CV burden is not yet known for incident COPD patients. We examined the risk of severe CV events in incident COPD patients in periods following either moderate and/or severe exacerbations. METHODS: Persons aged ≥ 40 years with an incident COPD diagnosis from the PHARMO Data Network were included. Exposed time periods included 1-7, 8-14, 15-30, 31-180 and 181-365 days following an exacerbation. Moderate exacerbations were defined as those managed in outpatient settings; severe exacerbations as those requiring hospitalisation. The outcome was a composite of time to first severe CV event (acute coronary syndrome, heart failure decompensation, cerebral ischaemia, or arrhythmia) or death. Hazard ratios (HR) were estimated for association between each exposed period and outcome. RESULTS: 8020 patients with newly diagnosed COPD were identified. 2234 patients (28%) had ≥ 1 exacerbation, 631 patients (8%) had a non-fatal CV event, and 461 patients (5%) died during a median follow-up of 36 months. The risk of experiencing the composite outcome was increased following a moderate/severe exacerbation as compared to time periods of stable disease [range of HR: from 15.3 (95% confidence interval 11.8-20.0) in days 1-7 to 1.3 (1.0-1.8) in days 181-365]. After a moderate exacerbation, the risk was increased over the first 180 days [HR 2.5 (1.3-4.8) in days 1-7 to 1.6 (1.3-2.1) in days 31-180]. After a severe exacerbation, the risk increased substantially and remained higher over the year following the exacerbation [HR 48.6 (36.9-64.0) in days 1-7 down to 1.6 (1.0-2.6) in days 181-365]. Increase in risk concerned all categories of severe CV events. CONCLUSIONS: Among incident COPD patients, we observed a substantial risk increase of severe CV events or all-cause death following either a moderate or severe exacerbation of COPD. Increase in risk was highest in the initial period following an exacerbation. These findings highlight the significant cardiopulmonary burden among people living with COPD even with a new diagnosis.

Outcomes in patients with lung cancer treated with crizotinib and erlotinib in routine clinical practice: A post-authorization safety cohort study conducted in Europe and in the United States.

PURPOSE: We examined safety outcomes of interest (SOI) and overall survival (OS) among lung cancer patients initiating crizotinib and erlotinib in routine clinical practice. METHODS: This descriptive cohort study used routinely collected health data in Denmark, Finland, Sweden, the Netherlands, and the United States (US) during 2011-2017, following crizotinib commercial availability in each country. Among crizotinib or erlotinib initiators, we reported baseline characteristics and incidence rates and cumulative incidences of the SOI - hepatotoxicity, pneumonitis/interstitial lung disease, QT interval prolongation-related events, bradycardia, vision disorders, renal cysts, edema, leukopenia, neuropathy, photosensitivity, malignant melanoma, gastrointestinal perforation, cardiac failure and OS. Results from the European Union (EU) countries were combined using meta-analysis; results from the US were reported separately. RESULTS: There were 456 patients in the crizotinib cohort and 2957 patients in the erlotinib cohort. Rates of the SOI per 1000 person-years in the crizotinib cohort ranged from 0 to 65 in the EU and from 0 to 374 in the US. Rates of the SOI per 1000 person-years in the erlotinib cohort ranged from 0 to 91 in the EU and from 3 to 394 in the US. In the crizotinib cohort, 2-year OS was ~50% in both EU and US. In the erlotinib cohort, 2-year OS was 21% in the EU and 35% in the US. CONCLUSIONS: This study describes clinical outcomes among lung cancer patients initiating crizotinib or erlotinib in routine clinical practice. Differences between SOI rates in EU and US may be partially attributable to differences in the underlying databases.

Increased risk for stress urinary incontinence in women with postmenopausal hormone therapy.

INTRODUCTION AND HYPOTHESIS: The impact of estradiol-based hormone therapy (HT) on the incidence of stress urinary incontinence (SUI) is unknown. Therefore, we compared the use of such HT regimens and tibolone in women with and without SUI. METHODS: The women with a history of SUI operation (N = 15,002) were identified from the Finnish National Hospital Discharge Register, and the control women without such an operation (N = 44,389) from the Finnish Central Population Register. The use of HT was traced from the National Drug Reimbursement Register, and the odd ratios (ORs) with 95% confidence intervals (95% CIs) for SUI were calculated by using the conditional logistic regression analysis. RESULTS: The cases had used any HT more often than the controls. The use of systemic estradiol-only or estradiol-progestin therapy was accompanied by an increased SUI risk (OR 3.8, 95% CI: 3.6-4.0 and OR 2.7, 95% CI: 2.6-2.9 respectively). The use of estradiol with noretisterone acetate showed a higher risk of increase than that with medroxyprogesterone acetate. Age over 55 years at the initiation of systemic HT was accompanied by a higher SUI risk increase than that under 55 years of age. The use of tibolone, an estradiol + levonorgestrel-releasing intrauterine device, or vaginal estradiol also increased the risk. CONCLUSIONS: The use of HT regimens may predispose to the de novo development or worsening of pre-existing SUI. Thus, caution is needed when these regimens are prescribed to women with mild stress-related urine leakage or with established SUI risk factors.

Exacerbations and healthcare resource utilization among COPD patients in a Swedish registry-based nation-wide study.

BACKGROUND: Exacerbations of chronic obstructive pulmonary disease (COPD) are an important measure of disease severity in terms of impaired disease progression, increased recovery time, healthcare resource utilization, overall morbidity and mortality. We aimed to quantify exacerbation and healthcare resource utilization rates among COPD patients in Sweden with respect to baseline treatments, exacerbation history, and comorbidities. METHODS: Patients with a COPD or chronic bronchitis (CB) diagnosis in secondary care at age of ≥40 years on 1.7.2009 were identified and followed until 1.7.2010 or death. Severe exacerbations were defined as hospitalizations due to respiratory disease, and healthcare resource utilization was measured by all-cause hospitalizations and secondary care visits. Poisson regression was used adjusting for age, gender, time since COPD/CB diagnosis, and Charlson comorbidity index. RESULTS: In 88,548 patients (54% females, mean age 72 years), previous respiratory hospitalizations and current high use of COPD medication (double or triple therapy) predicted an 8.3-fold increase in severe exacerbation rates and 1.8-fold increase in healthcare resource utilization rates in the following year, compared to patients without combination treatment and/or history of severe exacerbations. CONCLUSIONS: COPD/CB patients with history of severe exacerbations and high use of COPD medication experienced a significantly increased rate of severe exacerbations and healthcare resource utilization during the one-year follow-up.

Quality of warfarin therapy and risk of stroke, bleeding, and mortality among patients with atrial fibrillation: results from the nationwide FinWAF Registry.

PURPOSE: The most important management strategy in atrial fibrillation (AF) patients is preventing stroke with oral anticoagulants. Warfarin is still used as a first-line anticoagulant, although non-vitamin K antagonist oral anticoagulants are currently recommended to manage AF. Using a large, unselected national sample of AF patients, we evaluated the relationships between quality of warfarin therapy and the risks of thromboembolism, bleeding complications, and mortality. METHODS: The nationwide FinWAF study included 54 568 AF patients taking warfarin. Time in the therapeutic range (TTR) was calculated on a continuous basis using the Rosendaal method and international normalized ratio values over the previous 60 days. Adjusted Cox proportional hazard models were prepared for different TTR levels and major clinical end points. RESULTS: The mean age of patients was 73.1 years (standard deviation 10.8), and 47% were female. The mean follow-up time was 3.2 ± 1.6 years (median 3.4). In the TTR groups of ≤40%, 60-70%, 70-80%, and >80%, the annual risk of stroke was 9.3%, 4.7%, 4.6%, and 3.1%; bleeding events 7.5%, 4.5%, 4.3%, and 2.6%; and overall mortality 20.9%, 8.5%, 6.4%, and 3.1%, respectively. All differences among the TTR groups were highly significant (p < 0.001). CONCLUSIONS: The quality of warfarin treatment was strongly associated with the risk of stroke and the prognosis of AF patients. Patient outcomes continued to improve with increasing TTR values up to a TTR ≥80%; therefore, the target for the TTR should exceed 80% instead of the traditional range of at least 60-70%.

Vaginal estradiol use and the risk for cardiovascular mortality.

STUDY QUESTION: Does the use of post-menopausal vaginal estradiol (VE) affect the mortality risk for coronary heart disease (CHD) and stroke. SUMMARY ANSWER: The use of VE reduces the risk for cardiovascular mortality. WHAT IS KNOWN ALREADY: A growing number of women use VE for post-menopausal genitourinary symptoms. Although this therapy is intended to have only local effects, estrogen is absorbed into the blood circulation and thus VE use may also have systemic effects. STUDY DESIGN, SIZE, DURATION: We studied a nationwide cohort in Finland 1994-2009 during which post-menopausal women (n = 195 756) initiated the use of VE (age [mean ± SD] 65.7 ± 10.9 years). Follow-up data gathered 1.4 million women-years and we assessed the mortality risk due to CHD (n= 9656) or stroke (n = 4294). PARTICIPANTS/MATERIALS, SETTING, METHODS: The mortality risk in VE users was compared with that in the age-matched background population (standardized mortality ratio; [SMR]; 95% confidence interval) and related to various durations of exposure to VE (1 to ≤3, >3 to ≤5, >5 to ≤10 and >10 years). MAIN RESULTS AND THE ROLE OF CHANCE: The use of VE was accompanied by decreases in the risk for CHD and stroke death. The risk reduction for CHD death was highest for >3 to ≤5 years exposure (SMR 0.64; 0.57-0.70) and for stroke for >5 to ≤10 years exposure (SMR 0.64; 0.57-0.72). The risk reductions for both CHD and stroke mortality were detected in all age groups with the highest risk reduction being in women aged 50-59 years (SMR 0.43; 0.19-0.88 and SMR 0.21; 0.06-0.58, respectively). LIMITATIONS, REASONS FOR CAUTION: Our series lack a placebo arm and thus, may harbor a healthy woman bias. Moreover, data on clinical variables such as weight, smoking, blood pressure and family background were unobtainable for this study. Women using both VE and systemic hormone therapy (HT) were included in the comparator background population. This should not cause any significant error because the proportion of women using VE or other HT was modest (<10% in age-matched population) and because the use of systemic HT also reduces death risks in the same population. Our data cannot be directly applied for local regimens containing conjugated equine estrogens, because they are absorbed differently and may show effects that differ from those of estradiol. WIDER IMPLICATIONS OF THE FINDINGS: In 1000 women using VE for up to 10 years, a maximum of 24 fewer CHD deaths and 18 fewer stroke deaths is likely to occur.

Entacapone and prostate cancer risk in patients with Parkinson's disease.

BACKGROUND: The association between Parkinson's disease (PD) and prostate cancer, both common in elderly men, is disputable. In the STRIDE-PD study, prostate cancer developed in 9 patients (3.7%) receiving levodopa/carbidopa with entacapone, a catechol-O-methyltransferase inhibitor, versus 2 cases (0.9%) without entacapone. The current pharmacoepidemiological study aimed to determine whether entacapone increases prostate cancer incidence or mortality in PD patients and whether cumulative exposure affects these rates. METHODS: We performed a retrospective cohort study using population-wide health care registers with patient-level linkage. Prostate cancer incidence and mortality were modeled by Cox's proportional hazards models. RESULTS AND CONCLUSIONS: Use of entacapone with l-dopa/dopa decarboxylase inhibitor caused no increased risk of prostate cancer incidence (hazard ratio [HR]: 1.05; 95% confidence interval: 0.76-1.44) or mortality (0.93; 0.43-1.98). The HR for cumulative entacapone use of >360 days versus never-use was 0.82 (0.56-1.18) for prostate cancer incidence and 1.27 (0.60-2.72) for prostate cancer mortality.

Comparative analysis of Streptococcus pneumoniae transmission in Portuguese and Finnish day-care centres.

BACKGROUND: Day-care centre (DCC) attendees play a central role in maintaining the circulation of Streptococcus pneumoniae (pneumococcus) in the population. The prevalence of pneumococcal carriage is highest in DCC attendees but varies across countries and is found to be consistently lower in Finland than in Portugal. We compared key parameters underlying pneumococcal transmission in DCCs to understand which of these contributed to the observed differences in carriage prevalence. METHODS: Longitudinal data about serotype-specific carriage in DCC attendees in Portugal (47 children in three rooms; mean age 2 years; range 1-3 years) and Finland (91 children in seven rooms; mean age 4 years; range 1-7 years) were analysed with a continuous-time event history model in a Bayesian framework. The monthly rates of within-room transmission, community acquisition and clearing carriage were estimated. RESULTS: The posterior mean of within-room transmission rate was 1.05 per month (Portugal) vs. 0.63 per month (Finland). The smaller rate of clearance in Portugal (0.57 vs. 0.73 per month) is in accordance with the children being younger. The overall community rate of acquisition was larger in the Portuguese setting (0.25 vs. 0.11 per month), in agreement with that the groups belonged to a larger DCC. The model adequately predicted the observed levels of carriage prevalence and longitudinal patterns in carriage acquisition and clearance. CONCLUSIONS: The difference in prevalence of carriage (61% in Portuguese vs. 26% among Finnish DCC attendees) was assigned to the longer duration of carriage in younger attendees and a significantly higher rate of within-room transmission and community acquisition in the Portuguese setting.

Evaluation of the incidence and risk of hypoglycemic coma associated with selection of basal insulin in the treatment of diabetes: a Finnish register linkage study.

OBJECTIVE: Long-acting basal insulin analogs have demonstrated positive effects on the balance between effective glycemic control and risk of hypoglycemia versus neutral protamine Hagedorn (NPH) insulin in randomized controlled trials. Evidence of severe hypoglycemic risk with insulin detemir, insulin glargine, or NPH insulin is presented from a nationwide retrospective database study. RESEARCH DESIGN AND METHODS: Data from hospital and secondary healthcare visits due to hypoglycemic coma from 75 682 insulin-naïve type 1 or 2 diabetes patients initiating therapy with NPH insulin, insulin glargine, or insulin detemir in Finland between 2000 and 2009 were analyzed. Incidence rates with 95% confidence intervals (CIs) were calculated using Poisson regression. Hazard ratios were estimated using Cox's regression with adjustments for relevant background variables. RESULTS: The adjusted risk of hospital/secondary healthcare visits due to the first severe hypoglycemic event was 21.7% (95% CI 9.6-32.1%, p < 0.001) lower for insulin detemir and 9.9% (95% CI 1.5-17.6%, p = 0.022) lower for insulin glargine versus NPH insulin. Risk of hypoglycemic coma recurrence was 36.3% (95% CI 8.9-55.5%, p = 0.014) lower for detemir and 9.5% but not significantly (95% CI -10.2 to 25.7%, p = 0.318) lower for glargine versus NPH insulin. Risk of all hypoglycemic coma events was 30.8% (95% CI 16.2-42.8%, p-value <0.001) lower for detemir and 15.6% (95% CI 5.1-25.0%, p-value 0.005) lower for glargine versus NPH. Insulin detemir had a significantly lower risk for first (13.1% lower [p = 0.034]), recurrent (29.6% lower [p = 0.021]), and all (17.9% lower [p = 0.016]) severe hypoglycemic events than insulin glargine. CONCLUSIONS: There were considerable differences in risk of hospitalization or secondary healthcare visits due to hypoglycemic coma between basal insulin treatments in real-life clinical practice.

Prenatal exposure to pregabalin, birth outcomes and neurodevelopment - a population-based cohort study in four Nordic countries.

INTRODUCTION: Pregabalin is an antiepileptic drug frequently prescribed to pregnant women. Risks of adverse birth and postnatal neurodevelopmental outcomes following prenatal exposure to pregabalin are uncertain. OBJECTIVE: To investigate the association between prenatal exposure to pregabalin and the risks of adverse birth and postnatal neurodevelopmental outcomes. METHODS: This study was conducted using population-based registries in Denmark, Finland, Norway, and Sweden (2005-2016). We compared pregabalin exposure against no exposure to antiepileptics and against active comparators lamotrigine and duloxetine. We obtained pooled propensity score-adjusted estimates of association using fixed-effect and Mantel-Haenszel (MH) meta-analyses. RESULTS: The total number of pregabalin-exposed births was 325/666,139 (0.05%) in Denmark, 965/643,088 (0.15%) in Finland, 307/657,451 (0.05%) in Norway, and 1275/1,152,002 (0.11%) in Sweden. The adjusted prevalence ratios (aPRs) with 95% confidence interval (CI) following pregabalin exposure versus no exposure were 1.14 (0.98-1.34) for major congenital malformations and 1.72 (1.02-2.91) for stillbirth, which attenuated to 1.25 (0.74-2.11) in MH meta-analysis. For the remaining birth outcomes, the aPRs were close to or attenuated toward unity in analyses using active comparators. Adjusted hazard ratios (95% CI) contrasting prenatal pregabalin exposure versus no exposure were 1.29 (1.03-1.63) for ADHD and attenuated when using active comparators, 0.98 (0.67-1.42) for autism spectrum disorders, and 1.00 (0.78-1.29) for intellectual disability. CONCLUSIONS: Prenatal exposure to pregabalin was not associated with low birth weight, preterm birth, small for gestational age, low Apgar score, microcephaly, autism spectrum disorders, or intellectual disability. On the basis of the upper value of the 95% confidence interval, increased risks greater than 1.8 were unlikely for any major congenital malformation and ADHD. For stillbirth and most groups of specific major congenital malformations, the estimates attenuated in MH meta-analysis.

Empagliflozin cardiovascular and renal effectiveness and safety compared to dipeptidyl peptidase-4 inhibitors across 11 countries in Europe and Asia: Results from the EMPagliflozin compaRative effectIveness and SafEty (EMPRISE) study.

BACKGROUND: Continued expansion of indications for sodium-glucose cotransporter-2 inhibitors increases importance of evaluating cardiovascular and kidney efficacy and safety of empagliflozin in patients with type 2 diabetes compared to similar therapies. METHODS: The EMPRISE Europe and Asia study is a non-interventional cohort study using data from 2014-2019 in seven European (Denmark, Finland, Germany, Norway, Spain, Sweden, United Kingdom) and four Asian (Israel, Japan, South Korea, Taiwan) countries. Patients with type 2 diabetes initiating empagliflozin were 1:1 propensity score matched to patients initiating dipeptidyl peptidase-4 inhibitors. Primary endpoints included hospitalization for heart failure, all-cause mortality, myocardial infarction and stroke. Other cardiovascular, renal, and safety outcomes were examined. FINDINGS: Among 83,946 matched patient pairs, (0·7 years overall mean follow-up time), initiation of empagliflozin was associated with lower risk of hospitalization for heart failure compared to dipeptidyl peptidase-4 inhibitors (Hazard Ratio 0·70; 95% CI 0.60 to 0.83). Risks of all-cause mortality (0·55; 0·48 to 0·63), stroke (0·82; 0·71 to 0·96), and end-stage renal disease (0·43; 0·30 to 0·63) were lower and risk for myocardial infarction, bone fracture, severe hypoglycemia, and lower-limb amputation were similar between initiators of empagliflozin and dipeptidyl peptidase-4 inhibitors. Initiation of empagliflozin was associated with higher risk for diabetic ketoacidosis (1·97; 1·28 to 3·03) compared to dipeptidyl peptidase-4 inhibitors. Results were consistent across continents and regions. INTERPRETATION: Results from this EMPRISE Europe and Asia study complements previous clinical trials and real-world studies by providing further evidence of the beneficial cardiorenal effects and overall safety of empagliflozin compared to dipeptidyl peptidase-4 inhibitors.

Modeling transmission of multitype infectious agents: application to carriage of Streptococcus pneumoniae.

We describe a novel Bayesian approach to estimate acquisition and clearance rates for many competing subtypes of a pathogen in a susceptible-infected-susceptible model. The inference relies on repeated measurements of the current status of being a non-carrier (susceptible) or a carrier (infected) of one of the n(q) > 1 subtypes. We typically collect the measurements with sampling intervals that may not catch the true speed of the underlying dynamics. We tackle the problem of incompletely observed data with Bayesian data augmentation, which integrates over possible carriage histories, allowing the data to contain intermittently missing values, complete dropouts of study subjects, or inclusion of new study subjects during the follow-up. We investigate the performance of the described method through simulations by using two different mixing groups (family and daycare) and different sampling intervals. For comparison, we describe crude maximum likelihood-based estimates derived directly from the observations. We apply the estimation algorithm to data about transmission of Streptococcus pneumonia in Bangladeshi families. The computationally intensive Bayesian approach is a valid method to account for incomplete observations, and we found that it performs generally better than the simple crude method, in particular with large amount of missing data.

Factors and their weight in reducing life expectancy in schizophrenia.

BACKGROUND: Schizophrenia is associated with a wide range of socioeconomic and health-related problems, as well as 10-25 potential life-years lost. While lifestyle choices, comorbidities, and choice of medication are associated with schizophrenia disease burden and mortality, real-world evidence on the impact of these factors on expected life-years among patients with schizophrenia is limited. METHODS: In this study, register-based, nationwide data from patients with schizophrenia in Finland during 1972-2015 were analysed to determine influential factors associated with mortality and to demonstrate their impact on expected life-years in patients with schizophrenia. RESULTS: Factors reducing all-cause mortality were use of antipsychotics: HR 0.46 (95 % CI: 0.45, 0.47), ever use of lipid-modifying agents: HR 0.71 (95 % CI 0.68, 0.73), antidepressants HR 0.87 (95 % CI 0.85, 0.90), and lithium HR 0.90 (95 % CI 0.86, 0.95). Factors increasing all-cause mortality were cardiovascular disease: HR 2.41 (95 % CI: 2.34, 2.49), liver disease: HR 1.98 (95 % CI: 1.78, 2.21), renal disease: HR 1.63 (95 % CI:1.56, 1.70), diabetes: HR 1.40 (95 % C:1.35, 1.45), history of switching antipsychotics: HR 1.39 (95 % CI: 1.35, 1.44), longer duration of previous hospitalisations HR 1.96 (95 % CI: 1.90, 2.02), history of substance abuse HR 1.38 (95 % CI: 1.30, 1.46), and ever use of benzodiazepines HR 1.12 (95 % CI: 1.09, 1.16). CONCLUSIONS: The results from this study could serve to motivate clinicians to support and encourage patients to adhere to antipsychotic treatment and achieve a healthier lifestyle, which could, in turn, increase the expected life-years of patients with schizophrenia.

Health and work disability outcomes in parents of patients with schizophrenia associated with antipsychotic exposure by the offspring.

This study aimed to identify if antipsychotic exposure in offspring is associated with psychiatric and non-psychiatric healthcare service use and work disability of their parents. This Swedish population-based cohort study was based on data comprising 10,883 individuals with schizophrenia, who had at least one identifiable parent in the nationwide registers, and their parents (N = 18,215). The register-based follow-up during 2006-2013 considered the level of antipsychotic exposure and persistence of use of the offspring, further categorized into first (FG) and second generation (SG) antipsychotics, and orals versus long-acting injections (LAIs). The main outcome measure was parental psychiatric healthcare service use, secondary outcomes were non-psychiatric healthcare use and long-term sickness absence. SG-LAI use was associated with a decreased risk (relative risks [RR] 0.81-0.85) of parental psychiatric healthcare use compared with not using SG-LAI, whereas oral antipsychotics were associated with an increased risk (RRs 1.10-1.29). Both FG- and SG-LAI use by the offspring were associated with a lower risk of long-term sickness absence (range of odds ratios 0.34-0.47) for the parents, compared with non-use of these drugs. The choice of antipsychotic treatment for the offspring may have an impact on work disability and healthcare service use of their parents.

Evaluating the Effectiveness of an Additional Risk Minimization Measure to Reduce the Risk of Prescribing Mirabegron to Patients with Severe Uncontrolled Hypertension in Four European Countries.

BACKGROUND: Mirabegron, indicated for the treatment of overactive bladder, is contraindicated in patients with severe uncontrolled hypertension (systolic blood pressure ≥180 mm Hg and/or diastolic blood pressure ≥110 mm Hg). In September 2015, a Direct Healthcare Professional Communication (DHPC) letter was disseminated as an additional risk minimisation measure. PURPOSE: To assess the effectiveness of the DHPC in reducing the proportions of patients with severe or non-severe uncontrolled hypertension at mirabegron initiation. METHODS: An observational multi-database cohort study was undertaken using routinely collected healthcare data (December 2012-December 2016) from the PHARMO Database Network (Netherlands), SIDIAP database (Spain), CPRD (United Kingdom, UK) and national healthcare registers and electronic medical records from Finland. DHPC effectiveness was evaluated using interrupted time series analyses comparing trends and changes in monthly proportions of severe or non-severe uncontrolled hypertensive mirabegron initiations relative to the timing of the DHPC dissemination. RESULTS: The study population comprised 52,078 patients. Prior to DHPC dissemination, across the four databases, 0.3-1.3% had severe uncontrolled hypertension. Estimated absolute changes (EAC) in proportions of severe uncontrolled hypertension post-DHPC indicated a tendency towards a lower proportion in the Netherlands (EAC -0.36%, p=0.053), unchanged proportions in Spain and the UK and a higher proportion in Finland (EAC +0.73%, p=0.016). For non-severe uncontrolled hypertension (13-16% pre-DHPC), post-DHPC proportions tended to be lower in the Netherlands (EAC -2.02%, p=0.038) and Spain (EAC -1.04%, p=0.071), and unchanged in the UK and Finland. CONCLUSION: Severe uncontrolled hypertension prior to mirabegron initiation was uncommon in these four European countries even before DHPC dissemination. This suggests that other risk minimisation communications (prior to the DHPC dissemination) had worked adequately with respect to minimising mirabegron use among patients with severe uncontrolled hypertension. No strong and consistent evidence of further risk minimisation after the DHPC dissemination was observed in this study.

Efficient Markov chain Monte Carlo implementation of Bayesian analysis of additive and dominance genetic variances in noninbred pedigrees.

Accurate and fast computation of quantitative genetic variance parameters is of great importance in both natural and breeding populations. For experimental designs with complex relationship structures it can be important to include both additive and dominance variance components in the statistical model. In this study, we introduce a Bayesian Gibbs sampling approach for estimation of additive and dominance genetic variances in the traditional infinitesimal model. The method can handle general pedigrees without inbreeding. To optimize between computational time and good mixing of the Markov chain Monte Carlo (MCMC) chains, we used a hybrid Gibbs sampler that combines a single site and a blocked Gibbs sampler. The speed of the hybrid sampler and the mixing of the single-site sampler were further improved by the use of pretransformed variables. Two traits (height and trunk diameter) from a previously published diallel progeny test of Scots pine (Pinus sylvestris L.) and two large simulated data sets with different levels of dominance variance were analyzed. We also performed Bayesian model comparison on the basis of the posterior predictive loss approach. Results showed that models with both additive and dominance components had the best fit for both height and diameter and for the simulated data with high dominance. For the simulated data with low dominance, we needed an informative prior to avoid the dominance variance component becoming overestimated. The narrow-sense heritability estimates in the Scots pine data were lower compared to the earlier results, which is not surprising because the level of dominance variance was rather high, especially for diameter. In general, the hybrid sampler was considerably faster than the blocked sampler and displayed better mixing properties than the single-site sampler.

Outbreaks of Streptococcus pneumoniae carriage in day care cohorts in Finland - implications for elimination of transmission.

BACKGROUND: Day care centre (DCC) attendees play a central role in maintaining the circulation of Streptococcus pneumoniae (pneumococcus) in the population. Exposure within families and within DCCs are the main risk factors for colonisation with pneumococcal serotypes in DCC attendees. METHODS: Transmission of serotype specific carriage was analysed with a continuous time event history model, based on longitudinal data from day care attendees and their family members. Rates of acquisition, conditional on exposure, were estimated in a Bayesian framework utilising latent processes of carriage. To ensure a correct level of exposure, non-participating day care attendees and their family members were included in the analysis. Posterior predictive simulations were used to quantify transmission patterns within day care cohorts, to estimate the basic reproduction number for pneumococcal carriage in a population of day care cohorts, and to assess the critical vaccine efficacy against carriage to eliminate pneumococcal transmission. RESULTS: The model, validated by posterior predictive sampling, was successful in capturing the strong temporal clustering of pneumococcal serotypes in the day care cohorts. In average 2.7 new outbreaks of pneumococcal carriage initiate in a day care cohort each month. While 39% of outbreaks were of size one, the mean outbreak size was 7.6 individuals and the mean length of an outbreak was 2.8 months. The role of families in creating and maintaining transmission was minimal, as only 10% of acquisitions in day care attendees were from family members. Considering a population of day care cohorts, a child-to-child basic reproduction number was estimated as 1.4 and the critical vaccine efficacy against acquisition of carriage as 0.3. CONCLUSION: Pneumococcal transmission occurs in serotype specific outbreaks of carriage, driven by within-day-care transmission and between-serotype competition. An amplifying effect of the day care cohorts enhances the spread of pneumococcal serotypes within the population. The effect of vaccination, in addition to reducing susceptibility to pneumococcal carriage in the vaccinated, induces a herd effect, thus creating a counter-effect to the amplifying effect of the cohort. Consequently, the critical vaccine efficacy against carriage, required for elimination of transmission, is relatively low. Use of pneumococcal conjugate vaccines is expected to induce a notable herd protection against pneumococcal disease.
