Occurrence of suicide and seasonal variation

OBJECTIVE: To review the estimated suicide rates for the Region Metropolitan, the main socio-political center in Chile, for the period 1979-1994, and to determine whether they follow a seasonal pattern. METHOD: Data available for the period 1979-94 at the Forensic Services in Chile was analyzed using ANOVA. RESULTS: It was register 5.386 suicides. While the "warm" months (October, November, December & January) concentrated 39.0% of cases, the so called "cold" months reported 28,7%. This contrast is made even clearer by the month-to-month analysis, showing the highest suicide rate in December (10.9%) against the lowest rate in June (7.0%). Further statistical analysis revealed these differences to be significant. CONCLUSION: The study shows that in Chile, representing as it does the Southern Hemisphere, the suicide rates tend to present a seasonal variation as has elsewhere been determined for in the North Hemisphere.

Sunshine and suicide at the tropic of Capricorn, São Paulo, Brazil, 1996-2004

Several studies have confirmed seasonal variation in suicide rates according to hours of sunshine. The suicide pattern was assessed in São Paulo, southeastern Brazil, at the tropic of Capricorn from 1996 to 2004. Poisson regression was employed to estimate parameters of seasonality, as well as to verify associations for each day between daylight duration and suicide. During the nine-year study period, there were 3,984 suicides (76.9% in men; median age=38.7 years old). Seasonal averages of suicides were similar, as were monthly averages. Poisson regression did not reveal any association between suicide rates and hours of sunshine (p=0.45) for both sexes. In conclusion, no seasonal pattern was observed for suicides.

Suicide attempts and substance use in an emergency room sample

OBJECTIVE: Describe suicide attempts assisted in an emergency room (ER) and acute substance consumption or dependence on these individuals. METHODS: Descriptive epidemiologic study was carried out during one year, evaluating suicide attempts assisted at Embu das Artes ER, São Paulo, Brazil. Patients were scheduled to a non structured psychiatric interview. Main outcomes measures were: socio demographic data, suicide attempt method, drugs or alcohol acute use in the six hours prior to attempt, patients with ICD-10 substance dependence diagnosis. The descriptive analyses and chi-square test (p < 0.05) were used to verify associations between the variables studied. RESULTS: sample was formed of 80 patients, mean age of 26.9 years (SD = 8.91), predominantly female (72.5%) and 21.2% adolescents. Most suicide attempts were made through medicine ingestion (62.5%). Approximately 21.2% and 7.5% related to have used alcohol and an illicit drug respectively within 6 hours prior to attempt and 10% were found to be substance dependent. All substance dependents had attempted suicide previously (p-value = 0.4). There was a significant association between suicide attempt through medicine ingestion and psychiatric treatment history (p = 0.02). CONCLUSION: More national studies are necessary to consider the role of alcohol and drug in suicide attempts assisted in ER, especially in chemical dependents whose suicidal behavior is relevant.

Presence of dual diagnosis between users and non-users of licit and illicit drugs in Brazil

ABSTRACT Objective Investigate the occurrence of dual diagnosis in users of legal and illegal drugs. Methods It is an analytical, cross-sectional study with a quantitative approach, non-probabilistic intentional sampling, carried out in two centers for drug addiction treatment, by means of individual interviews. A sociodemographic questionnaire, the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) and the Mini-International Neuropsychiatric Interview (MINI) were used. Results One hundred and ten volunteers divided into abstinent users (group 1), alcoholics (group 2) and users of alcohol and illicit drugs (group 3). The substances were alcohol, tobacco, crack and marijuana. A higher presence of dual diagnosis in group 3 (71.8%) was observed, which decreased in group 2 (60%) and 37.1% of drug abstinent users had psychiatric disorder. Dual diagnosis was associated with the risk of suicide, suicide attempts and the practice of infractions. The crack consumption was associated with the occurrence of major depressive episode and antisocial personality disorder. Conclusion It was concluded that the illicit drug users had a higher presence of dual diagnosis showing the severity of this clinical condition. It is considered essential that this clinical reality is included in intervention strategies in order to decrease the negative effects of consumption of these substances and provide better quality of life for these people.

Risk factors for suicide in multiple sclerosis: a case-control study

ABSTRACT Objective To evaluated the prevalence and the suicide risk in a Brazilian sample of patients with multiple sclerosis (MS) and to identify potential factors associated with the risk of suicide. A study was performed with outpatient with MS. The risk of suicide and the presence of psychiatric disorders were assessed by version 5.0 of the Mini-International Neuropsychiatric Interview (MINI). The sample of patients at risk for suicide was matched by sex and age to a control group of patients with MS. Results Eight point three percent of the patients had a past history of attempted suicide, and 8.3% had a current suicide risk, totaling 16.6%. The results of this study suggest that the risk factors associated with suicide in this population are depression, marital status single, widowed or divorced, and lower education level.

An Adenovirus Vector Containing the Suicide Gene Thymidine Kinase for a Broad Application in Cancer Gene Therapy

Treatment of cancer using gene therapy is based on adding a property to the cell leading to its elimination. One possibility is the use of suicide genes that code for enzymes that transform a pro-drug into a cytotoxic product. The most extensively used is the herpes simplex virus thymidine kinase (TK) gene, followed by administration of the antiviral drug ganciclovir (GCV). The choice of the promoter to drive the transcription of a transgene is one of the determinants of a given transfer vector usefulness, as different promoters show different efficiencies depending on the target cell type. In the experiments presented here, we report the construction of a recombinant adenovirus carrying TK gene (Ad-TK) driven by three strong promoters (P CMV IE, SV40 and EN1) and its effectiveness in two cell types. Human HeLa and mouse CCR2 tumor cells were transduced with Ad-TK and efficiently killed after addition of GCV. We could detect two sizes of transcripts of TK gene, one derived from the close together P CMV IE/SV40 promoters and the other from the 1.5 Kb downstream EN1 promoter. The relative amounts of these transcripts were different in each cell type thus indicating a higher flexibility of this system.

Depression and suicide risk among nursing professionals: an integrative review

Abstract OBJECTIVE Discussing the factors associated with major depression and suicide risk among nursing professionals. METHOD An integrative review in PubMed/MEDLINE, LILACS, SciELO and BDENF databases, between 2003 and 2015. RESULTS 20 published articles were selected, mostly from between 2012 and 2014, with significant production in Brazil. Nursing professionals are vulnerable to depression when young, married, performing night work and having several jobs, and when they have a high level of education, low family income, work overload, high stress, insufficient autonomy and a sense of professional insecurity and conflict in the family and workrelationship. Suicide risk was correlated with the presence of symptoms of depression, high levels of emotional exhaustion, depersonalization and low personal accomplishment; characteristics of Burnout Syndrome. CONCLUSION Suicide risk among nursing professionals is associated with symptoms of depression and correlated with Burnout Syndrome, which can affect work performance.

Scientific data dissemination a data catalogue to assist research organizations

The constant scientific production in the universities and in the research centers makes these organizations produce and acquire a great amount of data in a short period of time. Due to the big quantity of data, the research organizations become potentially vulnerable to the impacts on information booms that may cause a chaos as far as information management is concerned. In this context, the development of data catalogues comes up as one possible solution to the problems such as (I) the organization and (II) the data management. In the scientific scope, the data catalogues are implemented with the standard for digital and geospatial metadata and are broadly utilized in the process of producing a catalogue of scientific information. The aim of this work is to present the characteristics of access and storage of metadata in databank systems in order to improve the description and dissemination of scientific data. Relevant aspects will be considered and they should be analyzed during the stage of planning, once they can determine the success of implementation. The use of data catalogues by research organizations may be a way to promote and facilitate the dissemination of scientific data, avoid the repetition of efforts while being executed, as well as incentivate the use of collected, processed an also stored.

Intraocular pressure measurement in sheep using an applanation tonometer

The purpose of this study was to evaluate and establish the mean values of IOP in healthy adult sheep using an applanation tonometer. Information on age, sex, and breed was obtained for all animals included in this study. Twenty five healthy sheep (Ovis aries), of the same breed (Texel), male or female, with three years of age, received an ophthalmic examination in both eyes, including pupillary reflexes, Schirmer tear test, slit lamp biomicroscopy, and fluorescein staining. For all ophthalmic testing, animals were gently physically restrained, with no pressure in the jugular area and the eyelids were carefully open. IOP was measured by applanation tonometry (Tonopen XL). The same examiner performed the tonometry; measurements were taken three times for each eye, and their average was recorded as the IOP of the animal. Statistical analysis was performed using paired t-test and values of P < 0.05 were considered significant. The mean intraocular pressure in the whole group of 50 eyes was of 16.36 +/- 2.19 mm Hg. The mean (SD) IOP in the right eye was of 15.96 +/- 2.02 mm Hg, while the mean (SD) IOP in the left eye was of 16.76 +/- 2.32 mm Hg. Significant differences in IOP were not found between right and left eyes. The applanation tonometer was adequate for measuring the intraocular pressure in sheep. Reference data will assist in diagnosing testing for ophthalmic disease in sheep, as¹ well as promote further studies in this area.

Economic viability of the third milking in systems of production using closed-circuit mechanical milking

This study aimed to analyze the economic viability of the third milking in production systems using mechanical milking in a closed circuit, aiming to provide technicians and farmers with information to assist them in decision-making. Specifically, it intended: (a) to estimate the cost of one milking; (b) to estimate the cost of the third milking; (c) to develop a mathematical equation to estimate the minimum amount of milk produced with two milkings, from which it would be economically feasible to do the third milking. Data were collected from three dairy farms, from November 2010 to March 2011, keeping a twice-a-day milking frequency, with three data collections in each farm, totalizing nine collections. Considering the average data, it would be feasible to do the third milking if the average milk yield per day of lactating cows in a twice-a-day milking frequency was greater than or equal to 24.43 kg of milk.

Sistemas de informação em políticas sociais descentralizadas: uma análise sobre a coordenação federativa e práticas de gestão

Este artigo objetiva avaliar como sistemas de informa&#231;&#227;o criados pelo governo federal brasileiro s&#227;o utilizados para coordenar pol&#237;ticas sociais descentralizadas em tr&#234;s &#225;reas - sa&#250;de, educa&#231;&#227;o e assist&#234;ncia social - em que pol&#237;ticas p&#250;blicas federais s&#227;o implantadas em parceria com governos estaduais e municipais. Como parte deste estudo, foram realizadas 35 entrevistas semiestruturadas realizadas entre o final de 2012 e in&#237;cio de 2013 com gestores dos tr&#234;s programas estudados e nos tr&#234;s n&#237;veis de governo. Al&#233;m disso, como informa&#231;&#227;o complementar, coletamos 432 question&#225;rios que foram respondidos por usu&#225;rios dos mesmos sistemas. Como referencial te&#243;rico para an&#225;lise, utilizamos um modelo multin&#237;vel constru&#237;do a partir da combina&#231;&#227;o de tr&#234;s teorias - social construtivismo, contextualismo e estruturacionismo - e que vem sendo utilizado em v&#225;rios estudos relacionados com o uso de sistemas de informa&#231;&#227;o com finalidade social. O estudo conclui que sistemas desenvolvidos considerando a participa&#231;&#227;o dos diferentes n&#237;veis de governo tendem a ter melhor aceita&#231;&#227;o por parte dos usu&#225;rios e assim produzir melhores efeitos nos resultados das pol&#237;ticas aos quais est&#227;o associados. Os sistemas desenvolvidos de forma menos participativa tendem a focar exclusivamente a necessidade de controle pelo governo federal, subaproveitando seu potencial como instrumento de gest&#227;o e produzindo menor efeito de controle social da pol&#237;tica p&#250;blica a que est&#225; associado. Consequentemente, estes sistemas menos participativos t&#234;m menor relev&#226;ncia para a coordena&#231;&#227;o federativa.

Instrumentos e mecanismos de gest&#227;o: contribui&#231;&#245;es ao processo decis&#243;rio em conselhos de pol&#237;ticas p&#250;blicas

A administra&#231;&#227;o p&#250;blica no Brasil conta com diretrizes e par&#226;metros estabelecidos em documentos, a exemplo de leis, pol&#237;ticas ou planos, que se constituem em instrumentos para nortear e qualificar a gest&#227;o democr&#225;tica das pol&#237;ticas p&#250;blicas. A investiga&#231;&#227;o buscou identificar instrumentos e mecanismos de gest&#227;o utilizados no processo decis&#243;rio pelos Conselhos Municipais de Assist&#234;ncia Social e de Sa&#250;de em Chapec&#243; (SC). A partir da leitura de atas (2005 a 2009), obtiveram-se como instrumento mais citado os relat&#243;rios de presta&#231;&#227;o de contas, embora esses n&#227;o evidenciarem articula&#231;&#227;o com objetivos e metas definidos no plano municipal. Os mecanismos mais utilizados s&#227;o comiss&#245;es internas, capacita&#231;&#227;o, confer&#234;ncias e comunica&#231;&#227;o com outras organiza&#231;&#245;es. Os conselhos estudados recorrem a instrumentos e mecanismos com potencial para ampliar a participa&#231;&#227;o na gest&#227;o p&#250;blica municipal.

Health education: the role and functions of the specialist and the generalist

Education for health is a process in which all public health and medical care personnel are involved. People learn both formally (planned learning experiences) and informally (unplanned learning experiences). Since the patient, the client, the consummer and the community expect public health and medical care personnel to assist them with health and disease issues and problems, the response of the professional "educates" the customer whether the professional intends to educate or not. Therefore, it is incumbent on all public health and medical care professionals to understand their educational functions and their role in health education. It is also important that the role of the specialist in education be clear. The specialist, as to all other specialists, has an in-depth knowledge of his area of expertise, i.e., the teaching/learning process; s/he may function as a consultant to others to enhance the educational potential of their role or s/he may work with a team or with communities or groups of patients. Specific competencies and knowledge are required of the health education specialist; and there is a body of learning and social change theory which provides a frame of reference for planning, implementing and evaluating educational programs. Working with others to enhance their potential to learn and to make informed decisions about health/disease issues is the hallmark of the health education specialist.

Mortality among patients with non-affective functional psychoses in a metropolitan area of South-Eastern Brazil

High mortality rates among those suffering from schizophrenia and related psychoses have been consistently described in developed societies. However, to date there is a lack of data on this matter in Brazil. In order to examine this issue, a prospective 2-year follow-up study was carried out in S. Paulo. The sample consisted of 120 consecutive admissions to psychiatric hospitals in a defined catchment area, aged 18 to 44 years old, with clinical diagnoses of non-affective functional psychoses according to the ICD-9. After 2 years, 116 (96.7%) subjects were traced. During the study period there were 7 deaths (6.0% of those traced), 5 (4.3%) due to suicide. All but one of the suicides occurred in the first year after discharge from hospital. Age and sex Standardised Mortality Ratios (relative to rates for the population of the city of Sao Paulo) were 8.4 for overall mortality (95% confidence interval: 4.0-15.9) and 317.9 for deaths due to suicide (95% confidence interval: 125.2-668.3). These results are in agreement with previous studies, and show that in Brazil non-affective functional psychoses are life-threatening illnesses, which need adequate care, particularly when patients go back to live in the community after hospital discharge.
