Resumen Objetivo: Establecer la exposición ambiental a mercurio, para identificar el impacto sobre la salud de la población de niños y adolescentes en cuatro departamentos de Colombia. Metodología: Se llevó a cabo un estudio descriptivo transversal entre 2014 - 2015, en once municipios de los departamentos de Bolívar, Sucre, Antioquia y Córdoba y dentro de este se realizó un estudio anidado con un grupo de 63 niños y uno de 37 adolescentes de estos municipios. Resultados: El promedio de tiempo de residencia estuvo entre 6 y 9 años y se encontró alta frecuencia de consumo de pescado. El 6,3% de los niños y el 29,7% de los adolescentes, excedieron el límite permisible de mercurio en sangre y el 50,8% de los niños y el 46,0% de los adolescentes excedieron el límite permisible en cabello. En cuanto a los síntomas referenciados por los participantes, hubo diferencia estadísticamente significativa (p>0,05), entre la población de niños y la de adolescentes en salivación excesiva (15,9%), caída del cabello (18,7%), insomnio (29,0%), nerviosismo (19,6%), debilidad (18,0%) y pérdida de memoria (17,3%). Sabor metálico en la boca (8,4%), pérdida de peso (23,4%), temblor (21,5%), problemas de concentración (17,9%) y dolor torácico (17,9%) no mostraron diferencia entre estos dos grupos. Conclusión: Los niños y adolescentes que residen en áreas de explotación de oro o influenciados por la minería de oro, se encuentran expuestos a mercurio, lo que implica un riesgo elevado para su salud.

Abstract Objective: It was proposed to establish the environmental exposure to mercury, to identify the impact on the health of the population of children and adolescents in four departments of Colombia. Methodology: A cross-sectional descriptive study was carried out between 2014 - 2015, in eleven municipalities of the departments of Bolívar, Sucre, Antioquia and Córdoba and within this a nested study was carried out with a group of 63 children and 37 adolescents from these municipalities. Results: Average residence time between 6 and 9 years and a high frequency of fish consumption was found. 6.3% of children and 29.7% of adolescents exceeded the allowable limit of mercury in blood and 50.8% of children and 46.0% of adolescents exceeded the permissible limit on hair. Regarding the symptoms referenced by the participants, there was a statistically significant difference (p> 0.05) between the population of children and that of adolescents in excessive salivation (15.9%), hair loss (18.7%), insomnia (29.0%), nervousness (19.6%), weakness (18.0%) and memory loss (17.3%). Metallic taste in the mouth (8.4%), weight loss (23.4%), tremor (21.5%), concentration problems (17.9%) and chest pain (17.9%) did not show difference between the two groups. Conclusions: Children and adolescents who reside in areas of gold exploitation or who are influenced by gold mining are exposed to mercury, which implies a high risk to their health.

ResumoEste artigo apresenta o Emotion Regulation Profile(ERP) como um instrumento para medir diferenças individuais na regulação de emoções. O ERP é constituído por 15 cenários que apresentam situações características de eventos da vida cotidiana desprazerosos (nove cenários) ou prazerosos (seis cenários). Cada cenário avalia a quantidade de respostas adaptativas/funcionais e desadaptativas/disfuncionais dos participantes. O instrumento foi aplicado a uma amostra de 686 pessoas entre 18 e 51 anos de idade. A amostra foi sudividida em dois grupos de 343 participantes para procedimentos de análises fatoriais exploratórias e confirmatórias. Os resultados da análise de componentes principais (primeira amostra) corroborou a estrutura bifatorial identificada no estudo original da medida, isto é, um fator de regulação das emoções negativas (down regulation) e um fator de regulação das emoções positivas (up regulation). Além disso, um conjunto de análises fatoriais confirmatórias (segunda amostra) mostrou que a estrutura bifatorial proposta teve um bom ajustamento aos dados. Por fim, foi possível propor uma versão reduzida do ERP com seis cenários (três que descrevem situações desprazerosas e três prazerosas) para avaliar adequadamente as diferentes estratégias usadas pelas pessoas na regulação de suas emoções.

AbstractThis article presents the Emotion Regulation Profile (ERP) as an instrument for measuring individual differences in the regulation of emotions. The ERP consists of 15 vignettes that portray everyday life situations describing pleasant (nine vignettes) and unpleasant (six vignettes) events. Each vignette assesses the number of adaptive/functional and maladaptive/dysfunctional responses chosen by the participants. The instrument was administered to a sample of 686 people between the ages of 18 and 51. The sample was divided into two groups of 343 participants each so that exploratory and confirmatory factor analysis could be conducted. Results from the principal component analysis (first sample) corroborated the bifactorial structure identified in the original study of the measure, that is, a regulation of negative emotion factor (down regulation) and a regulation of positive emotion factor (up regulation). Furthermore, a set of confirmatory factor analysis (second sample) revealed that the proposed bifactorial structure showed good fit indices. Finally, it was possible to propose a reduced version of the ERP with six vignettes (three describing pleasant events and three describing unpleasant events) to adequately assess the different strategies people use when regulating their emotions.

Objective: Characterizing the technical quality of occupational medicine services being provided by occupational health supply providing institutions (OHSPI) in Colombia’s main cities. Materials and Methods: This was a national descriptive cross-sectional study (2009- 2010) in which a diagnostic survey was used for obtaining data regarding 192 OHSPI. Results: The study demonstrated that 76 % of the OHSPI had a license for offering occupational medicine services. Institutions provide services by subcontracting professionals and the necessary equipment. It also revealed infrequent use of integral attention for evidence-based occupational health guidelines (EBOHG). Conclusion: Deficiencies affecting the quality of occupational medicine services were identified. Such deficiencies hampered in-depth studies about the effects of the risk factors on workers’ health, meaning that monitoring and controlling occupational health care services offered by the OHSPI must be reinforced to assure the availability of resources and the execution of disease prevention programs to maintain and improve workers’ state of health.

Objetivo: Caracterizar la calidad técnica de los servicios que en el área de medicina del trabajo ofertan las instituciones prestadoras de servicios de salud ocupacional (IPSSO) en las principales ciudades del país. Métodos: Corresponde a un estudio descriptivo de corte transversal (2009-2010) de cobertura nacional (15 ciudades) en el que mediante la aplicación de una encuesta diagnóstica se obtuvo información de 192 Instituciones Prestadoras de Servicios de Salud Ocupacional (IPSSO). Resultados: El estudio evidenció que el 74,7 % de las IPSSO cuentan con licencia vigente para la prestación de servicios en el área de medicina del trabajo, que la oferta de servicios se realiza sobre la base de la subcontratación tanto de profesionales como de equipos y que el uso de las guías de atención integral en salud ocupacional basadas en la evidencia (GATISO), es muy incipiente. Conclusiones: Se identificaron, entre otras, deficiencias técnicas, administrativas, de gestión, de infraestructura y de personal, que afectan la calidad de los servicios de medicina del trabajo ofertados por las IPSSO, las cuales no permiten asegurar que se estén estudiando a profundidad y con suficiencia los efectos de los factores de riesgo en la salud de los trabajadores.

O objetivo deste trabalho foi delimitar indicadores clínicos e neuropsicológicos em crianças com suspeita de transtorno do déficit de atenção e hiperatividade (TDA/H). Foram avaliadas 150 crianças (idade de 7 a 14 anos) encaminhados ao NANI da UNIFESP. RESULTADOS: 75 crianças (55 M e 20 F) preenchiam os critérios para o TDA/H, dentre os quais 35 (46,6%) pacientes eram desatentos, 28 do tipo combinado e 12 do tipo hiperatividade/impulsivo. Observou-se correlação negativa com o escore de dígitos e no escore do teste de Corsi. Crianças com hiperatividade e impulsividade apresentaram baixo desempenho nas funções relacionadas à memória operacional. Crianças com transtorno opositor desafiante apresentaram alterações nos padrões de adaptação às mudanças do ritmo com menor adaptação às variações do tempo de exposição aos estímulos (Hit RT), além de maiores taxas de omissão no teste contínuo de performance. CONCLUSÃO: Este estudo sugere múltiplas interrelacões entre os escores em provas neuropsicológicas que são úteis para uma delimitação do perfil clínico de crianças com TDAH.

The aim of this study was to evaluate clinical and neuropsychological findings in children with suspicion of attention deficity hyperactivity disorder (ADHD). The assessment involved 150 children aged 7 to 14 referred to NANI at UNIFESP. RESULTS: 75 children (55 M and 20 F) fulfilled the criteria for ADHD, among which 35 were of the inattentive type, 28 of combined type and 12 were hyperactive/impulsive. There was negative correlation between the digit score and the Corsi test. Children with hyperactivity and impulsivity had a low performance for functional memory. Children with oppositional defiant disorder presented pattern changes in adaptability when there was a change in the rhythm the stimuli were presented and lower adaptation to time variability (Hit RT), in addition to higher rates of omission in the continuous performance test. CONCLUSION: This study suggests multiple interrelations between the scores of neuropsychological battery useful for detailed delimitation of the clinical profile of children with ADHD.
