Genetic diversity of Macroptilium accessions considering the increase in air temperature

Climate changes can influence the genetic diversity of forage plants, which may contribute to the improvement and development of new species. Therefore, this research aimed to evaluate the influence of temperature increase on the genetic diversity of Macroptilium accessions based on morphoagronomic descriptors. The experiment was carried out in a growth chamber in a 2×16 factorial arrangement (temperature regimes x Macroptilium accessions), with the temperatures consisting of T1 (20­26­33 °C) and T2 (24.8­30.8­37.8 °C) and 16 accessions. Eleven morphoagronomic descriptors allowed estimating the diversity among accessions. The measurements of genetic dissimilarity enabled us to observe the genetic distance between the studied materials, standing out the accessions T1.M3 and T2.S4 as the most divergent (446.01). The morphoagronomic descriptors percentage of leaves and stem diameter were the most efficient for estimating the diversity between access. Genetic variability points to the adaptation of Macroptilium accessions in the climate change scenario. The accessions more divergent can be explored in genetic breeding programs for the species aiming at the expansion of genetic variability as an adaptation mechanism to heat stress.

Variáveis clínicas e razões para busca de tratamento de pacientes tabagistas / Clinical variables and reasons smokers seek treatment / Variables clínicos y razones para búsqueda de tratamiento de pacientes tabagistas

OBJETIVO: identificar variáveis clínicas e razões para busca de tratamento de tabagistas. MÉTODOS: estudo retrospectivo documental, com pacientes assistidos no Centro de Atenção Psicossocial Álcool e outras drogas de 2013 a 2016. RESULTADOS: dos 211 usuários, 41 apresentaram dependência à nicotina: mulheres (68,3%), baixa escolaridade (70,7%), início precoce do tabagismo (82,9%), elevada/muito elevada (61%), presença de problemas psíquicos (78%) e ansiedade (58,5%). Na busca de tratamento, 85% das mulheres demonstraram preocupação com saúde e 73% custos elevados do cigarro. CONCLUSÃO: políticas públicas de intervenção e prevenção devem ser ampliadas e desenvolvidas com atenção especial às mulheres.

OBJECTIVE: to identify clinical variables and reasons for seeking treatment of smokers. METHODS: retrospective documentary study, with patients assisted at the Center for Psychosocial Care Alcohol and other drugs from 2013 to 2016. RESULTS: of the 211 users, 41 had nicotine dependence: women (68.3%), low level of schooling (70.7%). Early onset of smoking (82.9%), high / very high (61%), presence of psychic problems (78%) and anxiety (58,5%). In the search for treatment, 85% of the women showed health concern and 73% high cigarette costs. CONCLUSION: public intervention and prevention policies should be expanded and developed with special attention to women.

MÉTODOS: estudio retrospectivo documental, con pacientes asistidos en el Centro de Atención Psicosocial Alcohol y otras drogas de 2013 a 2016. RESULTADOS: en los 211 usuarios, 41 presentaron adicción a la nicotina: mujeres (68,3%), baja escolaridad (70,7%). El inicio temprano del tabaquismo (82,9%), elevada / muy elevada (61%), presencia de problemas psíquicos (78%) y ansiedad (58,5%). En la búsqueda de tratamiento, el 85% de las mujeres mostraron preocupación por la salud y el 73% de los altos costos del cigarrillo.
