Suicide in Brazil, 2004-2010: the importance of small counties.

OBJECTIVE: To describe suicide rates by county size in the five geopolitical areas of Brazil. METHODS: This was an ecological, descriptive study of suicide deaths in Brazil that occurred among the population 10 years of age and older in 2004-2010. Data were obtained from the National Mortality Information System of Brazil. Counties were defined by size as: very large (200,000+), large (< 200,000-100,000), medium (< 100,000-50,000), small (< 50,000-20,000), very small (< 20,000-10,000, and micro (< 10,000). Age-adjusted suicide rates were calculated for all counties and for population-size groups in each geopolitical area. Rate ratio and 95% confidence interval were used to compare suicide risk between groups and the reference. RESULTS: The national, average suicide mortality rate was 5.7 deaths/100,000 inhabitants. Except in the North and North-East, suicide mortality rates increased from the very large (> 200,000) to the micro counties (< 10,000 population). Very high rates were scattered in the North and Mid-West among the indigenous peoples (> 30 deaths per 100,000). At highest risk were micro counties in the South (13.6 deaths per 100,000), with elderly males (60+ years, 31.4) and males 40-59 years (31.3) being the sex/age group with the highest rates. CONCLUSIONS: To reduce suicide mortality in Brazil, public health authorities must support mental health training in small cities and multi-professional interventions among the indigenous peoples. In addition, the causes behind underreporting of suicide deaths must be resolved in several areas.

Psychiatric comorbidity and suicidal behavior in epilepsy: a community-based case-control study.

PURPOSE: To provide information about psychiatric comorbidity and suicidal behavior in people with epilepsy compared to those without epilepsy from a community sample in Brazil. METHODS: An attempt was made to evaluate all 174 subjects with epilepsy (cases) identified in a previous survey. For every case identified, an individual without epilepsy (control) matched by sex and age was selected in the same neighborhood. A structured interview with validated psychiatric scales was performed. One hundred and fifty-three cases and 154 controls were enrolled in the study. RESULTS: People with epilepsy had anxiety more frequently [39.4% vs. 23.8%, odds ratio (OR) 2.1, 95% confidence interval (CI) 1.2-3.5; p = 0.006], depression (24.4% vs. 14.7%, OR 1.9, 95% CI 1.01-3.5; p = 0.04), and anger (55.6% vs. 39.7%, OR 1.9, 95% CI 1.2-3.1; p = 0.008). They also reported more suicidal thoughts [36.7% vs. 23.8%, OR 1.8, 95% CI 1.1-3.1; p = 0.02), plans (18.2% vs. 3.3%, OR 2.0, 95% CI 1.0-4.0; p = 0.04), and attempts (12.1% vs. 5.3%, OR 2.4, 95% CI 1.1-3.2, p = 0.04) during life than controls. CONCLUSIONS: These findings call attention to psychiatric comorbidity and suicidal behavior associated with epilepsy. Suicide risk assessment, mental evaluation, and treatment may improve quality of life in epilepsy and ultimately prevent suicide.

Suicidal thoughts in epilepsy: a community-based study in Brazil.

Epilepsy has been associated with increased risk of suicide; however, few studies have examined the relationship between epilepsy and suicidal behavior. The aims of this study were to evaluate the frequency of suicidal behavior in people with epilepsy and to identify characteristics that are associated with suicidal ideation in epilepsy. Of 171 people with epilepsy identified in a previous survey, 139 were included. A structured interview was conducted, and a second psychiatric evaluation was scheduled for those who agreed. The frequencies of suicidal thoughts, plans, and attempts during lifetime were 36.7, 18.2, and 12.1%, respectively. The following conditions were strongly associated with suicidal thoughts: anxiety (OR=3.3, 95% CI=1.4-7.5, P=0.001), depression (OR=4.8, 95% CI=1.9-12.5, P=0.001), and two or more standardized psychiatric diagnoses (OR=21.6, 95% CI=4.4-105.9, P<0.0001). Although specific characteristics of epilepsy were found to be related to suicidal thoughts, psychiatric diseases also play an essential role.

[Detecting suicide risk at psychiatric emergency services]. / Detecção do risco de suicídio nos serviços de emergência psiquiátrica.

OBJECTIVE: Guide the health professional to identify risk factors and forms of protection, together with handling such patient throughout a clinical interview within the emergency service context. METHOD: Selected literature revision so as to identify relevant and illustrative key cases. RESULTS: The clinical interview is the best method to evaluate the suicidal risk and has two different aims: 1) emotional support and creation of a bond; 2) collecting information. There is a substantial amount of information to be collected during the clinical interview, such as: risk factors and protection, epidemiologic data, act characterization, psychical dynamics aspects, personal and familial historic patterns, identification models, data on physical wealth and social net support. Difficulties are to emerge throughout the clinical interview, but a trained and informed professional will be able to approach and adequately add the patient. Although several scales have been proposed, none of them have been efficient to deter the suicidal risk. CONCLUSION: There is no method to predict who is to commit suicide, nevertheless, it is possible to evaluate the individual risk of each patient with regards to a detailed and empathic clinical interview. Prevent the patient to commit suicide is the preliminary and fundamental rule.

Depression, alcohol use disorders and nicotine dependence among patients at a general hospital.

OBJECTIVE: To determine prevalence rates and identify patient characteristics associated with depression, alcohol use disorders and nicotine dependence among individuals admitted to a general teaching hospital. METHOD: Using the Hospital Anxiety and Depression Scale and Alcohol Use Disorder Identification Test, we assessed 4,352 consecutive medical and surgical patients admitted over a 13-month period. The patients were also asked to report their daily cigarette smoking habits during the last month. Multiple logistic regression analyses were performed, and odds ratios (ORs) were calculated. RESULTS: The mean age of the sample was 49.3 years, and 56.6% were male. Prevalence rates of depression, alcohol use disorders and nicotine dependence were, respectively, 14%, 9.8% and 16.9%. In the multivariate analysis, depression was associated with previous suicide attempts (OR = 8.7), lower level of education (OR = 3.6), prior use of psychotropic medications (OR = 3.1), cancer (OR = 1.7) and pain (OR = 1.7). Alcohol use disorders were associated with male sex (OR = 6.3), smoking (OR = 3.5), admission for an external cause of injury, such as a traffic accident (OR = 2.4), and previous suicide attempts (OR = 2.3). Nicotine dependence was associated with alcohol use disorders (OR = 3.4), young adulthood (OR = 2.3), widowhood (OR = 2.2) and previous suicide attempts (OR = 1.8). CONCLUSION: This is the largest sample of medical and surgical patients ever surveyed with standardized screening instruments in a general hospital in Brazil. The high prevalence rates of psychiatric disorders and the profiles of the patients evaluated in this study underscore the need to develop methods that are more effective for detecting and managing such disorders. Hospital admission should be considered a major opportunity for the detection of psychiatric disorders and the subsequent implementation of the appropriate specific treatment strategies.

[Depression and suicidal behavior of cancer inpatients: prevalence and associated factors]. / Depressão e comportamento suicida em pacientes oncológicos hospitalizados: prevalência e fatores associados.

OBJECTIVE: To determine prevalence rates of depression and suicidal behavior among cancer inpatients and factors associated with these conditions. METHODS: A total of 5357 patients consecutively admitted to a university hospital were assessed by means of the Hospital Anxiety and Depression Scale (HAD) and the suicide risk section of the Mini International Neuropsychiatric Interview (MINI). Univariate analyses adjusted for gender and age groups were performed with depression and suicide risk as dependent variables. RESULTS: Of those assessed, 675 had cancer. The prevalence rates for depression and suicide risk were 18.3% (95%CI = 15.4 - 21.4) and 4.7% (95%CI = 3.2 - 6.7) respectively. Depression was more frequently found in cancer bearers than in the other inpatients (13.2%; p = 0.0009). Female gender, low schooling level, long time of disease, pain, use of psychotropic drugs and suicide risk were associated with depression (p < 0.05). Pain and depression were associated with suicide risk. CONCLUSION: Because prevalence rates of depression and suicide risk are high among cancer inpatients, simple screening instruments and specific questions during interviews are needed to detect these clinical conditions.

Factors associated with repeated suicide attempts. Preliminary results of the WHO Multisite Intervention Study on Suicidal Behavior (SUPRE-MISS) from Campinas, Brazil.

BACKGROUND: This study compares sociodemographic and clinical characteristics of 102 first-time hospital-treated suicide attempters (first-evers) with a group of 101 repeat suicide attempters (repeaters) consecutively admitted to a general hospital in Brazil, during the intake phase of the WHO Multisite Intervention Study on Suicidal Behaviors (SUPRE-MISS). AIMS: To compare sociodemographic and clinical characteristics of first-time hospital-treated suicide attempters (first-evers) with a group of repeat suicide attempters (repeaters). METHODS: A standardized interview and psychometric scales were administered to all patients. RESULTS: Repetition was associated with being of female sex (OR = 2.7; 95% confidence interval (CI) = 1.2-6.2), a housewife (OR = 3.8; 95% CI = 1.2-11.8), and having a score above median on the Beck Depression Inventory (OR = 5.2; 95% CI = 1.7-15.6). CONCLUSIONS: The findings suggest that repeaters, namely, depressed housewives who have attempted suicide previously, need specific treatment strategies in order to avoid future suicide attempts.

[Which are the recent clinical findings regarding the association between depression and suicide?]. / Quais são os recentes achados clínicos sobre a associação entre depressão e suicídio?

OBJECTIVE: Suicide is one of the leading causes of mortality worldwide, especially among young subjects. Suicide is considered the outcome of a multidimensional and complex phenomenon, which is a result of the interaction between several factors. The association between psychopathology and suicide has been extensively investigated. Major depression plays an important role among the psychiatric diagnoses associated with suicide. This finding seems to be confirmed by different study designs, and in distinct populations. The present paper aims to briefly review the recent findings regarding the suicide-related clinical features of depression. Moreover, strategies for suicide prevention were also reviewed. REVIEW: Recent references were identified and grouped in order to illustrate the main contributions about depression and suicide. Briefly, the literature review stresses the high prevalence of major depression among subjects presenting suicide behaviors. Psychopathological traits, such as aggression and impulsivity play a relevant role in triggering suicidal behaviors. Strategies for suicide prevention were also reviewed in Brazil and internationally. In general, detection and treatment are effective in reducing suicide rates. CONCLUSION: Studies regarding suicide behaviors have had a pragmatic approach, and generated a large body of evidence about correlates of suicide. However, these studies have not been able to provide a consistent theoretical explanation for this phenomenon. The recent adoption of modern strategies represents a possibility of enhancing the research capability of such studies. In order to be clinically useful, findings should make it possible to deepen the understanding over the experience of a suicidal person, as well as to design specific strategies for prevention and treatment in population subgroups.

[Therapeutic group for smokers: results after two-year follow-up]. / Grupo terapêutico para tabagistas: resultados após seguimento de dois anos.

OBJECTIVE: To evaluate the smokers' profile, immediate results and outcome after 25 months of treatment at a university public service. METHODS: One hundred and seventy one smokers were evaluated for treatment in the Therapeutic Group (TG) of the Service of Psychoactive Substances. We evaluated sociodemographic variables, history of smoking, presence of medical comorbidity and psychiatric symptoms, initial and late outcomes (median 25 months), by telephone contact. Frequency analysis and multiple logistic regression analysis were used, with a significance level of 5% for associated factors. RESULTS: Most patients were female (73.4%), married (48%), had basic education (74.6%), were working (57%); 65.2% started to smoke before the age of 15, 63.8% smoked for more than thirty years, 76% already had tried to stop smoking, 46.2% had severe dependence, 72.1% had medical comorbidity and 36% presented psychiatric symptoms. The service was sought by 51%, mainly concerned with health. During treatment, 79.1% stopped smoking. After 25 months, 62% remained abstinent. The variable associated with failure of smoking cessation was the presence of psychiatric symptoms. Variables related to relapse were psychiatric symptoms and lesser attendance at Motivation Group sessions. There was an association between clinical comorbidity and years of smoking and years of inactivity CONCLUSION: This study reinforces the importance of understanding the profile of the subjects to evaluate strategies employed and adequacy of treatment proposed for smokers to improve the rates of smoking cessation and reduce rates of relapse.

Effectiveness of brief intervention and contact for suicide attempters: a randomized controlled trial in five countries.

OBJECTIVE: To determine whether brief intervention and contact is effective in reducing subsequent suicide mortality among suicide attempters in low and middle-income countries. METHODS: Suicide attempters (n = 1867) identified by medical staff in the emergency units of eight collaborating hospitals in five culturally different sites (Campinas, Brazil; Chennai, India; Colombo, Sri Lanka; Karaj, Islamic Republic of Iran; and Yuncheng, China) participated, from January 2002 to October 2005, in a randomized controlled trial to receive either treatment as usual, or treatment as usual plus brief intervention and contact (BIC), which included patient education and follow-up. Overall, 91% completed the study. The primary study outcome measurement was death from suicide at 18-month follow-up. FINDINGS: Significantly fewer deaths from suicide occurred in the BIC than in the treatment-as-usual group (0.2% versus 2.2%, respectively; chi2 = 13.83, P < 0.001). CONCLUSION: This low-cost brief intervention may be an important part of suicide prevention programmes for underresourced low- and middle-income countries.

Religious affiliation and psychiatric morbidity in Brazil: higher rates among evangelicals and spiritists.

AIMS: To verify the association between the prevalence of mental symptoms and excessive alcohol intake with religious affiliation, church attendance and personal religiosity. METHODS: A household survey of 515 adults randomly sampled included the WHO SUPRE-MISS questionnaire, SRQ-20 and AUDIT. Weighted prevalences were estimated and logistic analyses were performed. RESULTS: Minor psychiatric morbidity was greater among Spiritists and Protestants/ Evangelicals than in Catholics and in the ;no-religion' group. The latter had a greater frequency of abusive alcohol drinking pattern and Protestants/Evangelicals showed lower drinking patterns. CONCLUSIONS: Although belonging to Protestant/Evangelical churches in Brazil may inhibit alcohol involvement it seems to be associated to a higher frequency of depressive symptoms. Processes of seeking relief in new religious affiliations among sub-groups with previous minor psychiatric symptoms may probably occur in the Brazilian society.

[Religion and psychiatric disorders in patients admitted to a university general hospital]. / Religião e transtornos mentais em pacientes internados em um hospital geral universitário.

In order to evaluate the prevalence of psychiatric disorders in a Brazilian general hospital and their association with religious denomination and religiosity, 253 inpatients were interviewed. A socio-demographic questionnaire and an instrument for diagnosis of mental disorders (MINI-Plus) were applied. Distribution of religious denominations was: Catholic 63.2% (n=177), Evangelical Protestant 20.4% (n=57), Spiritist 4.3% (n=12), traditional Protestant 2.3% (n=8), and "no religion" 7.5% (n=21). Degree of religiosity was: very religious 43.2% (n=116), religious 46.9% (n=129), hardly religious 9.8% (n=27), and not at all religious 1.1% (n=3). Evangelical (Pentecostal) religious affiliation and frequent attendance at worship services were associated with fewer alcohol problems. Membership in an Evangelical (Pentecostal) church may thus have an inhibitory effect on alcohol dependence or abuse. Intensity of religiosity was moderately associated with overall prevalence of disorders, especially bipolar disorder. It is reasonable to conclude that extreme situations (very intense versus very limited religious participation) are related to this finding, associating both an exacerbated pursuit of religion and alienation from it with altered mental states.

Gender differences in suicide attempts: preliminary results of the multisite intervention study on suicidal behavior (SUPRE-MISS) from Campinas, Brazil.

OBJECTIVE: To identify sociodemographic, psychosocial and clinical differences between men and women who attempted suicide and were seen at a university general hospital. METHOD: This is a non-controlled cross-sectional study, sub-project of the Multisite Intervention Study on Suicidal Behavior by the World Health Organization. A standardized interview that comprised psychometric scales was used. The comparison between genders was made by means of uni and multivariate logistic regression. RESULTS: 210 subjects (68.1% women) participated. Women had worse scores on the WHO Well-Being Index (p = 0.005), the Beck Depression Inventory (p = 0.01) and the Psychiatric Disability Assessment Schedule (p = 0.03). In the multivariate logistic regression, men presented more mental disorders due to alcohol and drug use (26.1% vs 7%, p = 0.02) and used alcohol at the suicide attempt more frequently (28.3% vs 16%, p = 0.03). Men reported that most of the time they had been feeling "active and vigorous" (50% vs 22%, p < 0.001). Women had had more physical and sexual abuse (27% vs 8.7%, p = 0.01). CONCLUSION: There are some distinctive characteristics between men and women who attempt suicide. Such differences may also be present in the general population and suggest there is a need for further studies, as well as the adoption of different strategies in suicide prevention for men and women.

Maintained attitudinal changes in nursing personnel after a brief training on suicide prevention.

Nursing personnel (N = 317) working at a general hospital attended a 6-hour training program on suicide prevention. They answered anonymously pre- and post-training the Suicide Behavior Attitude Questionnaire (SBAQ), which comprises 21 visual analogue scale items divided in three factorial subscales. The results indicated there were positive changes in the attitudes and these gains were significantly maintained at the 6-month follow-up evaluation. Improvement was in the Feelings and Professional Capacity subscales (ANOVA; p = 0.0001 and 0.01, respectively). There was no change on the Right to Suicide subscale. Because attitudes influence the effectiveness of health care personnel interventions, our findings may have important implications for the development of suicide prevention programs.

[Perception of community problems: the influence of socio-demographic and mental health factors]. / Percepção dos problemas da comunidade: influência de fatores sócio-demográficos e de saúde mental.

A cross-sectional study was designed to identify which social problems from a list of 17 were considered important and to analyze differences in perception among interviewees according to socio-demographic variables and presence of common mental disorders. A household survey was performed in Campinas, São Paulo, Brazil, with a stratified cluster sample of urban residents aged 14 years or older (N = 515) using the WHO/SUPRE-MISS interview and SRQ-20. Weighted prevalence and crude prevalence ratio with respective 95%CI were calculated. Multiple analyses were performed using Poisson regression. Drug traffic, drug abuse, unemployment, crime, and alcohol abuse were considered severe by more than 45% of the sample. Women and individuals living in medium-low income areas attributed greater severity to drug traffic, alcohol and drug abuse, child and spousal abuse, unemployment, and poverty. Females and individuals with positive SRQ-20 identified problems related to education as more severe. Differences in perception according to socioeconomic status and gender were observed, with women and low-income residents showing the greatest susceptibility.

Prevalence of alcohol abuse and associated factors in a population-based study.

OBJECTIVE: To estimate the prevalence of alcohol abuse/dependence and identify associated factors among demographic, family, socioeconomic and mental health variables. METHODS: A household survey was carried out in the urban area of Campinas, southeastern Brazil, in 2003. A total of 515 subjects, aged 14 years or more were randomly selected using a stratified cluster sample. The Self-Report Questionnaire and the Alcohol Use Disorder Identification Test were used in the interview. Prevalences were calculated, and univariate and multivariate logistic analyses performed by estimating odds ratios and 95% confidence intervals. RESULTS: The estimated prevalence of alcohol abuse/dependence was 13.1% (95% CI: 8.4;19.9) in men and 4.1% (95% CI: 1.9;8.6) in women. In the final multiple logistic regression model, alcohol abuse/dependence was significantly associated with age, income, schooling, religion and illicit drug use. The adjusted odds ratios were significantly higher in following variables: income between 2,501 and 10,000 dollars (OR=10.29); income above 10,000 dollars (OR=10.20); less than 12 years of schooling (OR=13.42); no religion (OR=9.16) or religion other than Evangelical (OR=4.77); and illicit drug use during lifetime (OR=4.47). Alcohol abuse and dependence patterns were different according to age group. CONCLUSIONS: There is a significantly high prevalence of alcohol abuse/dependence in this population. The knowledge of factors associated with alcohol abuse, and differences in consumption patterns should be taken into account in the development of harm reduction strategies.

Predictors of quality-of-life improvement following pulmonary resection due to lung cancer.

CONTEXT AND OBJECTIVE: There is increasing involvement of health professionals in organizing protocols to determine the impact of lung surgery on functional state and activities of daily living, with the aim of improving quality of life (QoL). The objective of this study was to investigate predictors of QoL improvement among patients undergoing parenchyma resection due to lung cancer. DESIGN AND SETTING: Prospective study, at teaching hospital of Universidade Estadual de Campinas (Unicamp). METHODS: 36 patients with lung cancer diagnosis were assessed before surgery and on the 30th, 90th and 180th days after surgery. The Short-Form Health Survey (SF-36) was used as the dependent variable. The independent variables were the Hospital Anxiety and Depression (HAD) scale, a six-minute walking test (6-MWT), a visual analogue scale for pain, forced vital capacity (FVC), type of surgery and use of radiotherapy and chemotherapy. Generalized estimation equations (GEE) were utilized. RESULTS: The median age for these 20 men and 16 women was 55.5 +/- 13.4 years. Both FVC and 6-MWT were predictors of improvement in the physical dimensions of QoL (p = 0.011 and 0.0003, respectively), as was smaller extent of surgical resection (p = 0.04). The social component of QoL had improved by the third postoperative month (p = 0.0005). CONCLUSION: The predictors that affected QoL positively were better FVC and 6-MWT results and less extensive lung resection. Three months after the surgery, an improvement in social life was already seen.

Crack users, sexual behavior and risk of HIV infection.

OBJECTIVE: To compare a sample of injecting cocaine users and crack users, assessing sexual behavior, risk for infection by HIV and its seroprevalence. METHOD: 109 injecting cocaine users and 132 crack users were assessed, using the World Health Organization questionnaire from the expanded "Cross-Site Study of Behaviors and HIV Seroprevalence among Injecting Drug Users" and HIV serology. Data were assessed by Multiple Correspondences Analysis. RESULTS: Crack users showed less time of drug consumption when compared to the injecting cocaine users. Despite this fact, they had higher rates of risky sexual activity, differences in poli-consumption of drugs, and higher rates of involvement in illegal issues. HIV seroprevalence among crack users, although lower than for injecting cocaine users (7% vs. 33%) is high when compared to the general population at the same age. CONCLUSIONS: Sexual behavior of crack users in the studied sample may be considered a risk factor for HIV infection. Crack users have access to information on HIV/ AIDS, but do not make use of it to change risk behaviors that may expose them to HIV infection and dissemination. HIV seroprevalence among crack users (7%) is concerning, which makes it necessary to create preventive strategies for HIV infection and dissemination that are specifically directed toward this population.

Social inequality and common mental disorders.

OBJECTIVE: To analyze the association between the socioeconomic characteristics of individuals and common mental disorders. METHOD: A cross-sectional survey of a representative sample of the urban population, 14 years and older, in Campinas (Brazil) (n=515) was conducted using a multipurpose instrument that included the Self-Reporting Questionnaire (SRQ-20) to assess common mental disorders in the previous 3 months. Weighted prevalence of common mental disorders was calculated for each independent variable. Crude and adjusted prevalence ratios were estimated using Poisson regression. RESULTS: The overall prevalence was 17% (95% CI 12.8-22.3), 8.9% in males and 24.4% in females. An inverse association was found between common mental disorders and the socioeconomic characteristics (schooling and employment) even after controlling for all the other variables. Higher common mental disorders prevalence was observed in those with less than 5 years of schooling (PR=5.5) and unemployed or underemployed (PR=2.0). CONCLUSIONS: As in other studies, common mental disorders were unevenly distributed; it was significantly more frequent in socially disadvantaged individuals. Specific actions to reduce inequalities in the general and mental health system should be studied.

Chronic use of diazepam in primary healthcare centers: user profile and usage pattern.

CONTEXT AND OBJECTIVE: Chronic use of benzodiazepines is frequent in general practice. The aim of this study was to describe the usage pattern and profile of chronic users of diazepam who had been consuming this drug for a minimum of thirty-six months continuously. DESIGN AND SETTING: This was a descriptive study (survey and clinical assessment) at five primary healthcare centers in Campinas, Brazil. METHODS: Psychotropic drug control books revealed 48 eligible patients. Among these, 41 were assessed by means of the Schedule for Clinical Assessment in Neuropsychiatry (SCAN), the Hospital Anxiety and Depression scale (HAD) and a questionnaire on usage pattern. RESULTS: Most patients were women (85.4%). The patients' mean age was 57.6 years, and they were from the social strata C (39%), D (54%) and E (7%). The mean length of diazepam consumption was 10 years. The patients presented a lack of prescription compliance and had made frustrated attempts to stop using the drug. 55.5% said their doctor had never given any guidance on the effects of the drug. According to SCAN, 25 patients (61%) suffered from depressive disorders; only 12 cases of benzodiazepine dependence were detected by this instrument. CONCLUSION: There is a need to improve the detection and treatment of mental disorders, as well as to prevent inappropriate prescription and use of benzodiazepines. Diazepam dependence has distinctive characteristics that make it undetected by SCAN.
