Characteristics associated with initiation of hormone replacement therapy among Finnish women : A register-linkage study

Objective: To investigate which patient characteristics are associated with the initiation of hormone replacement therapy (HRT) in a cohort of Finnish women. Study design: Responses to postal questionnaires distributed to a nationwide, randomly selected cohort of women in 1998, 2000, 2003, 2005 and 2010 were analyzed. The cohort members were aged 40-44 years at the beginning of the study. Information on hormone replacement therapy was received from the national prescription register. Women who started taking HRT between January 1, 1999 and December 31, 2011 were included and previous users were excluded from the analysis. Main outcome measures: Initiation of HRT was the main outcome measure. The following explanatory factors for predicting the use of HRT were examined: sociodemographic factors, personality, health behavior, physiological and mental symptoms, chronic diseases and use of psychopharmaceuticals. The associations between starting HRT and the explanatory factors were analyzed with single-predictor and multi-predictor logistic regression models. Results: Factors predicting that a woman would start taking HRT were: living with a partner, weak sense of coherence, BMI less than 30 kg/m(2), heavy or moderate alcohol use, symptoms of hyperactivity of the sympathetic nervous system, climacteric symptoms and use of psychopharmaceuticals. Conclusions: Women with a good sense of coherence can cope with climacteric symptoms without resorting to HRT. Clinicians need to bear in mind the burden of menopausal symptoms on a woman's personal and working life when HRT is being considered. (C) 2016 Elsevier Ireland Ltd. All rights reserved.Peer reviewe

Change in β2-agonist use after severe life events in adults with asthma: A population-based cohort study Life events and bronchodilator usage among adults with asthma

Objective: This prospective, population-based cohort study of 1102 Finnish adults with asthma, examined whether exposure to stressful life events is associated with the intensity of usage of inhaled short-acting beta(2)-agonists.Methods: Survey data was collected by two postal questionnaires. Baseline characteristics were obtained in 1998 and data on 19 specific stressful events (e.g. death of a child or spouse or divorce) within the six preceding months in 2003. Exposure to life events was indicated by a sum score weighted by mean severity of the events. Participants were linked to records of filled prescriptions for inhaled short-acting beta(2)-agonists from national registers from 2000 through 2006. The rates of purchases of short-acting beta(2)-agonists before (2000 2001), during (2002 2003) and after (2004-2006) the event exposure were estimated using repeated-measures Poisson regression analyses with the generalized estimating equation.Results: Of the 1102 participants, 162 (15%) were exposed to highly stressful events, 205 (19%) to less stressful events. During the 7-year observation period, 5955 purchases of filled prescription for inhaled short-acting beta(2)-agonists were recorded. After exposure to highly stressful events, the rate of purchases of beta(2)-agonists was 1.50 times higher (95% confidence interval (CI): 1.05, 2.13) than before the stressful event occurred. Among those with low or no exposure to life events, the corresponding rate ratios were not elevated (rate ratio 0.81, 95% CI: 0.66, 0.99 and 0.95, 95% CI: 0.83, 1.09 respectively).Conclusion: An increase in beta(2)-agonist usage after severe life events suggests that stressful experiences may worsen asthma symptoms

The long-term cost of childhood conduct problems: Finnish Nationwide 1981 Birth Cohort Study

Background Commonly recognized childhood conduct problems often lead to costly problems in adulthood. This study aimed to evaluate the long-term cumulative cost of childhood conduct problems until the age of 30. The costs included inpatient care, nervous system medicine purchases, and criminal offences. Methods The study used population-based nationwide 1981 birth cohort data. Families and teachers assessed the conduct problems of the eight-year-olds based on Rutter questionnaires. We grouped 5,011 children into low-level of conduct problems (52%), intermediate-level of conduct problems (37%), and high-level of conduct problems (11%) groups, based on combined conduct symptoms scores. The analysis included the cohort data with the Care Register for Health Care, the Drug Prescription Register, and the Finnish Police Register. The cost valuation of service use applied national unit costs in 2016 prices. We used Wilcoxon rank-sum test to test the differences between groups and gender. Results During 1989-2011, average cumulative costs of the high-level (euro44,348, p < .001) and the intermediate-level (euro19,405, p < .001) of conduct problems groups were higher than the low-level of conduct problems group's (euro10,547) costs. In all three groups, the boys' costs were higher than girls' costs. Conclusions The costs associated with conduct problems in childhood are substantial, showing a clear need for cost-effective interventions. Implementation decisions of interventions benefit from long-term cost-effectiveness modelling studies. Costing studies, like this, provide cost and cost offset information for modelling studies

Beat-to-beat cardiac repolarization lability increases during hypoxemia and arousals in obstructive sleep apnea patients

: Obstructive sleep apnea (OSA) is associated with the progression of cardiovascular diseases, arrhythmias, and sudden cardiac death (SCD). However, the acute impacts of OSA and its consequences on heart function are not yet fully elucidated. We hypothesized that desaturation events acutely destabilize ventricular repolarization, and the presence of accompanying arousals magnifies this destabilization. Ventricular repolarization lability measures, comprising heart rate corrected QT (QTc), short-time-variability of QT (STVQT), and QT variability index (QTVI), were calculated before, during, and after 20,955 desaturations from lead II electrocardiography signals of 492 patients with suspected OSA (52% men). Variations in repolarization parameters were assessed during and after desaturations, both with and without accompanying arousals, and groupwise comparisons were performed based on desaturation duration and depth. Regression analyses were used to investigate the influence of confounding factors, comorbidities, and medications. The standard deviation (SD) of QT, mean QTc, SDQTc, and STVQT increased significantly (P &lt; 0.01), whereas QTVI decreased (P &lt; 0.01) during and after desaturations. The changes in SDQT, mean QTc, SDQTc, and QTVI were significantly amplified (P &lt; 0.01) in the presence of accompanying arousals. Desaturation depth was an independent predictor of increased SDQTc (β = 0.405, P &lt; 0.01), STVQT (β = 0.151, P &lt; 0.01), and QTVI (β = 0.009, P &lt; 0.01) during desaturation. Desaturations cause acute changes in ventricular repolarization, with deeper desaturations and accompanying arousals independently contributing to increased ventricular repolarization lability. This may partially explain the increased risk of arrhythmias and SCD in patients with OSA, especially when the OSA phenotype includes high hypoxic load and fragmented sleep.NEW &amp; NOTEWORTHY Nocturnal desaturations are associated with increased ventricular repolarization lability. Deeper desaturations with accompanying arousals increase the magnitude of alterations, independent of confounding factors, comorbidities, and medications. Changes associated with desaturations can partially explain the increased risk of arrhythmias and sudden cardiac death in patients with OSA, especially in patients with high hypoxic load and fragmented sleep. This highlights the importance of detailed electrocardiogram analytics for patients with OSA
