Abstract
In the present study, pure-tone audiometry was used in 687 Finnish school children, aged 6-15 years, to determine the prevalence of a 6 kHz acoustic dip and related factors among three age groups. Trained audiometricians tested air conduction thresholds in a sound-proof room. A total of 57 children (8.3%) had a clear-cut dip of at least 20 dB at 6 kHz. This dip was more pronounced in older children and in boys. A thorough case history was obtained by questionnaire, with logistic regression analysis showing that low birth weight (

Venous Thromboembolism - epidemiology - mortality
Abstract
Studies on long-term mortality after venous thromboembolism (VTE) are sparse.
Using Danish medical databases, we conducted a 30-year nationwide population-based cohort study of 128 223 patients with first-time VTE (1980-2011) and a comparison cohort of 640 760 people from the general population (without VTE) randomly matched by sex, year of birth, and calendar period. The mortality risks for patients with deep venous thrombosis (DVT) and pulmonary embolism (PE) were markedly higher than for the comparison cohort during the first year, especially within the first 30 days (3.0% and 31% versus 0.4%). Using Cox regression, we assessed mortality rate ratios (MRRs) with 95% confidence intervals (CIs). The overall 30-year MRR was 1.55 (95% CI, 1.53-1.57) for DVT and 2.77 (95% CI, 2.74-2.81) for PE. The 30-day MRR was 5.38 (95% CI, 5.00-5.80) for DVT and 80.87 (95% CI, 76.02-86.02) for PE. Over time, the 30-day MRR was consistently 5- to 6-fold increased for DVT, whereas it improved for PE from 138 (95% CI, 125-153) in 1980 to 1989 to 36.08 (95% CI, 32.65-39.87) in 2000 to 2011. The 1- to 10-year and 11- to 30-year MRRs remained 25% to 40% increased after both DVT and PE but were 3- to 5-fold increased after DVT and 6- to 11-fold increased after PE when VTE was considered the immediate cause of death.
Patients with VTE are at increased risk of dying, especially within the first year after diagnosis, but also during the entire 30 years of follow-up, with VTE as an important cause of death. Although 30-day mortality after DVT remained fairly constant over the last 3 decades, it improved markedly for PE.

Abstract
Attitudes concerning the acceptability of suicide have been emphasized as being important for understanding why levels of suicide mortality vary in different societies across the world. While Russian suicide mortality levels are among the highest in the world, not much is known about attitudes to suicide in Russia. This study aims to obtain a greater understanding about the levels and correlates of suicide acceptance in Russia.
Data from a survey of 1,190 Muscovites were analysed using logistic regression techniques. Suicide acceptance was examined among respondents in relation to social, economic and demographic factors as well as in relation to attitudes towards other moral questions.
The majority of interviewees (80%) expressed condemnatory attitudes towards suicide, although men were slightly less condemning. The young, the higher educated, and the non-religious were more accepting of suicide (OR > 2). However, the two first-mentioned effects disappeared when controlling for tolerance, while a positive effect of lower education on suicide acceptance appeared. When controlling for other independent variables, no significant effects were found on suicide attitudes by gender, one's current family situation, or by health-related or economic problems.
The most important determinants of the respondents' attitudes towards suicide were their tolerance regarding other moral questions and their religiosity. More tolerant views, in general, also seemed to explain the more accepting views towards suicide among the young and the higher educated. Differences in suicide attitudes between the sexes seemed to be dependent on differences in other factors rather than on gender per se. Suicide attitudes also seemed to be more affected by one's earlier experiences in terms of upbringing and socialization than by events and processes later in life.

Abstract
Geographical access to health care facilities is known to influence health services usage. As societies age, accessibility to health care becomes an increasingly acute public health concern. It is known that seniors tend to have lower mobility levels, and it is possible that this may negatively affect their ability to reach facilities and services. Therefore, it becomes important to examine the mobility situation of seniors vis-a-vis the spatial distribution of health care facilities, to identify areas where accessibility is low and interventions may be required.
Accessibility is implemented using a cumulative opportunities measure. Instead of assuming a fixed bandwidth (i.e. a distance threshold) for measuring accessibility, in this paper the bandwidth is defined using model-based estimates of average trip length. Average trip length is an all-purpose indicator of individual mobility and geographical reach. Adoption of a spatial modelling approach allows us to tailor these estimates of travel behaviour to specific locations and person profiles. Replacing a fixed bandwidth with these estimates permits us to calculate customized location- and person-based accessibility measures that allow inter-personal as well as geographical comparisons.
The case study is Montreal Island. Geo-coded travel behaviour data, specifically average trip length, and relevant traveller's attributes are obtained from the Montreal Household Travel Survey. These data are complemented with information from the Census. Health care facilities, also geo-coded, are extracted from a comprehensive business point database. Health care facilities are selected based on Standard Industrial Classification codes 8011-21 (Medical Doctors and Dentists).
Model-based estimates of average trip length show that travel behaviour varies widely across space. With the exception of seniors in the downtown area, older residents of Montreal Island tend to be significantly less mobile than people of other age cohorts. The combination of average trip length estimates with the spatial distribution of health care facilities indicates that despite being more mobile, suburban residents tend to have lower levels of accessibility compared to central city residents. The effect is more marked for seniors. Furthermore, the results indicate that accessibility calculated using a fixed bandwidth would produce patterns of exposure to health care facilities that would be difficult to achieve for suburban seniors given actual mobility patterns.
The analysis shows large disparities in accessibility between seniors and non-seniors, between urban and suburban seniors, and between vehicle owning and non-owning seniors. This research was concerned with potential accessibility levels. Follow up research could consider the results reported here to select case studies of actual access and usage of health care facilities, and related health outcomes.

Abstract
This study examined (1) disparities in the proportion of persons who accessed a physician for treatment of a diagnosed mental disorder across 17 health regions in Alberta, Canada, and (2) the extent to which regional disparities in physician access could be explained by differences in regional demographies, population needs, or physician supply.
The study illustrates the use of ecological comparisons for regional health system performance evaluations. Regional characteristics were aggregated from four sources of data: the health insurance registry file (population denominators and regional demographies), physician claims data (treatment access), census data (social indicators of population need), and the medical directory of the College of Physicians of Surgeons (physician supply).
Regional variability in needs-adjusted measures of access to physician-based treatment services were comparatively small (varying by a factor of 1.6). Models containing adjustments for demography, need, and physician supply explained 41% of regional variation in access. Of the total variation explained, physician supply explained a smaller proportion (39%) in comparison to social demography and needs (61%). Few large regional imbalances were noted when needs-adjusted and supply-adjusted estimates were compared. Only two areas appeared to be underserviced in comparison to their local needs, reflecting approximately 6% of the provincial population.
While all three study factors proved important, findings support the broad conclusion that social demography and social risk (a proxy for need) will remain the key determinants predicting access to physician services for treatment of mental disorders in publicly funded health systems.

Abstract
We cross-validated two actuarial risk assessment tools, the RRASOR (R. K. Hanson, 1997) and the Static-99 (R. K. Hanson & D. Thornton, 1999), in a retrospective follow-up (mean follow-up time = 3.69 years) of all sex offenders released from Swedish prisons during 1993-1997 (N = 1,400, all men, age > or =18 years). File-based data were collected by a researcher blind to the outcome (registered criminal recidivism), and individual risk factors as well as complete instrument characteristics were explored. Both the RRASOR and the Static-99 showed similar and moderate predictive accuracy for sexual reconvictions whereas the Static-99 exhibited a significantly higher accuracy for the prediction of any violent recidivism as compared to the RRASOR. Although particularly the Static-99 proved moderately robust as an actuarial measure of recidivism risk among sexual offenders in Sweden, both procedures may need further evaluation, for example, with sex offender subpopulations differing ethnically or with respect to offense characteristics. The usefulness of actuarial methods for the assessment of sex offender recidivism risk is discussed in the context of current practice.

Abstract
Despite the negative physical and mental health outcomes of sexual assault, a minority of sexually assaulted women seek immediate post-assault medical and legal services. This study identified the number and types of acute forensic medical procedures used by women presenting at a hospital-based urgent care centre between 1997 and 2001 within 72 hours following a reported sexual assault. The study also examined assault and non-assault factors associated with the use of procedures. It was hypothesized that assault characteristics resembling the stereotype of rape would be associated with the use of more procedures. The multiple regression indicated that injury severity, coercion severity, homelessness, and delay in presentation were significantly associated with the number of procedures received. Findings provide partial support for the hypothesis that post-assault procedures would be associated with the stereotype of rape, and highlight homeless women as a group particularly at risk for not receiving adequate medical treatment following a sexual assault.

Abstract
To examine the prevalence of acute stress disorder (ASD) after a myocardial infarction (MI) and the factors associated with its development.
Of 1344 MI patients admitted to three Canadian hospitals, 474 patients did not meet the inclusion criteria and 393 declined participation in the study; 477 patients consented to participate in the study. A structured interview and questionnaires were administered to patients 48 hours to 14 days post MI (mean +/- standard deviation = 4 +/- 2.73 days).
Four percent were classified as having ASD using the Structured Clinical Interview for DSM-IV, ASD module. The presence of symptoms of depression (Beck Depression Inventory; odds ratio (OR) = 29.92) and the presence of perceived distress during the MI (measured using the question "How difficult/upsetting was the experience of your MI?"; OR = 3.42, R(2) = .35) were associated with the presence of symptoms of ASD on the Modified PTSD Symptom Scale. The intensity of the symptoms of depression was associated with the intensity of ASD symptoms (R = .65). The models for the detection and estimation of ASD symptoms were validated by applying the regression equations to 72 participants not included in the initial regressions. The results obtained in the validation sample did not differ from those obtained in the initial sample.
The symptoms of depression and the subjective distress during the MI could be used to improve the detection of ASD.

Abstract
Comparison of outcomes among intensive care units (ICUs) requires adjustment for patient variables. Severity of illness scores are associated with hospital mortality, but administrative databases rarely include the elements of these scores. However, these databases include the elements of comorbidity scores. The purpose of this study was to compare the value of these scores as adjustment variables in statistical models of hospital mortality and hospital and ICU length of stay after adjustment for other covariates.
We used multivariable regression to study 1808 patients admitted to a 13-bed medical-surgical ICU in a 400-bed tertiary hospital between December 1998 and August 2003.
For all patients, after adjusting for age, sex, major clinical category, source of admission, and socioeconomic determinants of health, we found that Acute Physiology and Chronic Health Evaluation (APACHE) II and comorbidity scores were significantly associated with hospital mortality and that comorbidity but not APACHE II was significantly associated with hospital length of stay. Separate analysis of hospital survivors and nonsurvivors showed that both APACHE II and comorbidity scores were significantly associated with hospital length of stay and APACHE II score was associated with ICU length of stay.
The value of APACHE II and comorbidity scores as adjustment variables depends on the outcome and population of interest.
