ABSTRACT

BACKGROUND: The evidence-based heart failure (HF) drug treatment is made of a ß-blocker and an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker, or hydralazine + isosorbide dinitrate. Little is known about sex-based difference in adherence to the evidence-based HF drug treatment. OBJECTIVES: To assess among new users of the evidence-based HF drug treatment, the association between sex and 1) persistence with the treatment 1 year after its initiation, 2) implementation of the treatment among those who persisted, and 3) overall adherence to treatment in the year following its initiation. METHODS: A cohort study was conducted among new users of this treatment using Quebec medico-administrative data. Patients still on the evidence-based HF drug treatment one year after initiation were considered persistent. Among persistent users, those with ≥88% of days covered by the treatment were deemed to have adequately implemented it. Persistent patients who have adequately implemented the treatment were considered adherent. To measure the association between, on one hand sex, and on the other persistence, implementation and adherence, adjusted proportion ratios (APR) with their 95% confidence intervals (CI) were calculated. RESULTS: Among 13,453 women, 72.1% were persistent, 72.2% adequately implemented the treatment, and 52.8% were adherent. Among the 14,614 men, these proportions were 73.6%, 67.9% and 50.1%, respectively. Men were less likely than women to be adherent to their treatment (APR: 0.96, 95% CI: 0.94-0.99). CONCLUSION: Among individuals initiating an evidence-based multi-drug treatment for HF, men are less likely than women to be adherent to this treatment.

ABSTRACT

The performance and removal mechanisms of a hybrid constructed wetland (HCW) followed by a willow planted filter (WPF) were evaluated for the treatment of a leachate contaminated by wood pole preservatives (pentachlorophenol (PCP) and chromated copper arsenate) to reach the storm sewer discharge limits. The HCW aimed to dechlorinate the PCP and polychlorodibenzo-p-dioxins/polychlorodibenzofuran (PCDD/F) and to remove metals by adsorption and precipitation. The HCW was efficient in removing PCP (>98.6%), oil, arsenic (99.4%), chromium (>99.2%), copper (>99.6%%) and iron (29%) to under their discharge limits, but it was unable to reach those of Mn and PCDD/F, with residual concentrations of 0.11 mg Mn/L and 0.32 pg TEQ/L. Iron and manganese could be removed but were subsequently released by the HCW due to low redox conditions. No dechlorination of PCDD/F was observed since its chlorination profile remained the same in the different sections of the HCW. Adsorption was the most probable removal mechanism of PCDD/F. The WPF was able to remove some residual contamination, but it released Mn at a gradually decreasing rate. Total evapotranspiration of the leachate by a larger fertilized WPF and the construction of an underground retention basin are proposed to prevent any discharge of PCDD/F traces in the environment.

ABSTRACT

BACKGROUND: Little is known about exposure to heart failure (HF) treatment among seniors with ischemic heart disease. OBJECTIVES: In a population of seniors, we: 1) estimated the association between age and exposure to HF drug therapy at 6, 12, 36 and 60 month intervals after HF diagnosis, and 2) determined the influence of the passage of time on exposure to drug therapy. METHODS: Using the Quebec provincial administrative databases, we conducted a population-based inception cohort study that included all individuals aged ≥ 65 with a first HF diagnosis between 2000 and 2009 and an ischemic heart disease diagnosis in the year before HF diagnosis. We assessed exposure to HF drug therapy and to drug therapy at target doses at 6, 12, 36 and 60 month intervals after HF diagnosis. Adjusted prevalence ratios (aPR) between age at diagnosis and exposure to drug therapy and the influence of time (6-month periods) were assessed using multivariate modified Poisson regressions. RESULTS: Among the 86,428 seniors, those who were older were less likely to be exposed to both HF drug therapy and drug therapy at target doses at each time point, than were the younger ones (aged 65-69). The aPRs for exposure to drug therapy for the 90+ age group were 0.64, 0.64, 0.56 and 0.53 at the 6, 12, 36 and 60 month intervals, respectively. After HF diagnosis, exposure increased by a maximum of 8% per 6-month period. CONCLUSION: Increasing age is associated with a decrease in exposure to drug therapy, with only slight improvement in exposure after HF diagnosis.

ABSTRACT

BACKGROUND: Avahan, the India AIDS Initiative, is a large-scale targeted intervention. Data on condom use prior to Avahan are unavailable. The authors used a novel method of analysing cross-sectional survey data to 'reconstruct' condom use rates in presurvey years, and to assess the relationship between Avahan and time trends in condom use among female sex workers (FSWs). METHODS: Among FSWs reporting consistent condom use (CCU) with clients in surveys from 21 districts in southern India (n=7358), data on length of time using condoms, and length of time selling sex, were converted into number of FSWs using condoms (numerator) and selling sex (denominator) by year, to give yearly rates of CCU from 2001 to year of survey. Linear regression with generalised estimating equations was used to assess time trends and to compare the rate of increase in condom use before and after Avahan initiation in 2003. RESULTS: In all 21 districts, the rate of increase in CCU from 2001 to time of the surveys was highly significant. Overall CCU increased from 27% (22%) with occasional (regular) clients in 2001, to 76% (68%) in 2006, respectively. The yearly rate of increase in CCU was significantly greater after (slope 2003-2006: 12.7% (12.0%) per year for occasional (regular) clients) than prior to Avahan (slope 2001-2003: 5.1% (5.3%) per year for occasional (regular) clients) implementation (p<0.0001). CONCLUSIONS: The findings indicate a positive relationship between implementation of the Avahan programme and rates of CCU increase among FSW. This method of analysis may be useful in other contexts where preintervention data are lacking.

ABSTRACT

Measures of airway inflammation are increasingly being used as outcome measures in asthma intervention studies. Meaningful interpretation of observed changes in bronchial mucosal cell numbers should depend, in part, on the reproducibility of repeat measures over time. We wanted to investigate the reproducibility of immunopathologic and physiologic parameters after short and long measurement intervals. We therefore performed spirometry, bronchial provocation challenge, and fiberoptic bronchoscopy with endobronchial biopsy (always right upper lobe second-generation bronchus) at baseline, after 2 wk, and again after 8 wk on nine subjects with stable atopic asthma (receiving inhaled placebo and beta-agonist therapy only). Numbers of T cells, memory T cells (CD45Ro(+)), macrophages (CD68(+)), and eosinophils (EG1(+) and EG2(+)) on immunohistochemical stains of bronchial biopsies were quantified by computerized image analysis. Intraclass correlation coefficients (ICCs) of reproducibility were calculated for repeat measures of each parameter and a high ICC (greater than 0.6) was interpreted as "highly reproducible." Repeat measures of FEV(1), FEF(25-75%), and PC(20) were highly reproducible after short (2-wk) and long (8-wk) intervals. Only repeat measures of EG2(+) had an ICC greater than 0.6 after 8 wk. Repeat measures of CD45Ro(+), EG2(+), and T cell numbers (but not CD68(+) and EG1(+) cells) are highly reproducible and reliable parameters of asthmatic airway inflammation after a 2 wk interval.

ABSTRACT

Seventy high school students completed the Vividness of Visual Imagery Questionnaire (VVIQ). Two months later, the 16 highest scores (low visualizers) and the 16 lowest scores (high visualizers) took part in a memory experiment involving abstract words, concrete words and pictures. Analyses of variance showed that high visualizers were superior to low visualizers on all three kinds of item in short-term recall, whereas they were only superior on the concrete words and pictures in long-term recall. Finally, both groups performed equally well on a subsequent recognition test. The results were interpreted as providing support for the validity of the VVIQ.
