Breastfeeding Twins: Factors Related to Weaning.

BACKGROUND: Many factors may influence a woman's decision to start and maintain breastfeeding. Research aim: This study aimed to investigate the factors associated with breastfeeding cessation in twin infants during the first 6 months after birth and to describe the main reasons for weaning cited by mothers of twins. METHODS: This is a secondary data analysis of a prospective randomized trial conducted in Brazil. Data were obtained through longitudinal quantitative and qualitative self-reported interviews. One hundred twenty-eight women pregnant with twins and their 256 infants were followed for up to approximately 6 months, during which time breastfeeding data were obtained through face-to-face interviews at three different points after birth: 30 to 40 days (Time 1), 90 days (Time 2), and 180 days (Time 3). The association between weaning and the investigated factors was examined using survival analysis methodologies. RESULTS: Nonexclusive breastfeeding ( p = .004, Cox proportional hazards regression model), a lack of support during the lactation period ( p = .001), difficulty breastfeeding ( p = .003), a breastfeeding duration shorter than 12 months in a previous pregnancy ( p = .001), and infants' birth weight less than 2,300 g ( p < .001) were the factors associated with breastfeeding cessation. The main reasons for weaning cited by mothers of twins were insufficient human milk supply, infants' behavior, and returning to work. CONCLUSION: We have identified the factors associated with weaning in twin infants during the first 180 days of life. This knowledge can help improve strategies to increase breastfeeding rates in twins.

Conjoined twins and legal authorization for abortion.

OBJECTIVE: To describe pregnancies with conjoined twins according to the request for legal termination of pregnancy. METHODS: Retrospective review of pregnancies with conjoined twins, with no possibility of extrauterine survival or postnatal surgical separation, observed at a tertiary teaching hospital, between 1998 and 2010. RESULTS: Amongst 30 cases seen during the study period, six (20.0%) couples decided to continue with the pregnancy, termination of pregnancy was not requested due to advanced gestational age (> 25 weeks) in 5 cases (16.7%). Legal authorization to terminate the pregnancy was requested in 19 (63.3%) cases: permission was granted in 12 (63.2%), denied in five (26.3%) and information was missing in two (10.5%) cases. A successful vaginal delivery was performed in 83.3% of the cases undergoing termination of pregnancy and a cesarean section was performed in all the remaining cases (p < 0.01). CONCLUSION: In pregnancies with conjoined twins and without fetal prognosis, legal termination of the pregnancy is an alternative. Moreover, a successful vaginal delivery can be performed in most cases before the third trimester, further reducing maternal risks and parental suffering.

Gêmeos unidos e autorização judicial para o aborto / Conjoined twins and legal authorization for abortion

OBJETIVO: Descrever casos de gravidez de gêmeos unidos de acordo com a solicitação de autorização judicial para interrupção gravidez. MÉTODOS: Análise retrospectiva das gestações de gêmeos unidos, sem possibilidade de sobrevida extrauterina ou de separação cirúrgica pós-natal, atendidos em um hospital terciário, entre 1998 e 2010. RESULTADOS: Entre 30 casos observados durante o período do estudo, seis (20,0 por cento) casais decidiram continuar com a gravidez, e, em cinco (16,7 por cento) casos, a autorização para interrupção da gestação não foi solicitada devido à idade gestacional avançada (> 25 semanas). A autorização para interromper a gravidez foi solicitada em 19 (63,3 por cento) casos: a permissão foi concedida em 12 (63,2 por cento), indeferida em cinco (26,3 por cento), e não se teve a informação do resultado em dois (10,5 por cento) casos. Nos casos submetidos à interrupção legal da gestação, o parto vaginal foi realizado em 83,3 por cento, e no grupo em que a autorização não foi concedida, a cesárea foi realizada em todos os casos (p < 0,01). CONCLUSÃO: A solicitação da autorização judicial para o aborto é uma alternativa na gravidez de gêmeos unidos sem prognóstico de sobrevida pós-natal. Além disso, o sucesso de um parto vaginal pode ser obtido na maioria dos casos antes do terceiro trimestre, reduzindo os riscos à saúde da mulher e o sofrimento do casal.
