In Brazil, as in many other countries, teenage pregnancy is widely recognised as a public health problem. Buttressed by a public health science of the economics of teenage pregnancy that emphasises the postponement of parenthood as key to poverty reduction, young people's lack of appreciation for medical knowledge of contraceptives is most often credited for failed attempts to reduce teenage pregnancy. Based on a longitudinal ethnographic study conducted in Pelotas, Brazil, with young people over the course of 10 years, our study found that young women who became teenage parents did not lack medical knowledge but were, rather, highly medicalised. Not only were they intensely concerned with the ill-effects of oral contraceptives on possible future fertility, they also engaged in intricate routines of contraceptive-use as a way of testing and safeguarding their fecundity. Our analysis attends to the way these practices are shaped by the problematisation of the economics of teenage pregnancy, as well as by the gendering of cultural norms relating to the transition to adulthood. We theorise the results by considering how contraceptive medicalisation enabled some women to engage with the authority of normative society, while developing a potent off-stage critique of this authority and of what they considered to be discriminatory messages imbedded in scientific discourses on teenage pregnancy.

After removal of artefacts, the mean monitoring time was 22 h08 (8 h54). All patients had impaired cerebral autoregulation during their monitoring time. The mean IAR index was 17 (9.5) %. During H 0 H 6 and H 18 H 24 , the majority of our patients; respectively 53 and 71 % had an IAR index > 10 %. Conclusion According to our data, patients with septic shock had impaired cerebral autoregulation within the first 24 hours of their admission in the ICU. In our patients, we described a variability of distribution of impaired autoregulation according to time. ReferencesSchramm P, Klein KU, Falkenberg L, et al.

Previous studies have shown that the inclusion of medium chain fatty acids (MCFA) results in an improvement in nursery pig performance. Therefore, the objective of this study was to evaluate a proprietary C8:C10 MCFA blend (CaptiSURE, Kemin Industries, Inc., Des Moines, IA) on nursery pig performance. A total of 360 weaned piglets (initial BW = 6.1 kg) were randomly assigned to a control (no MCFA blend) or 10 kg/t MCFA blend (10 pigs/pen, 18 replicate pens/treatment), in which MCFA blend was substituted at the expense of tallow at a 1:1 rate. Diets were manufactured in 3 dietary phases (d 0–7, 7–21, and 21–42) in pelleted form. Due to an unintended bacterial challenge at the sow farm, pigs were treated with amoxicillin using a pulse protocol (48 hrs on / 48 hrs off) from placement to d 21. Data were analyzed using the students T-test procedure, and pen served as the experimental unit. Within dietary phase 2 (d 7–21), the inclusion of MCFA blend improved ADG (264g vs 326g, P = 0.017) and G:F (0.79 vs 0.89, P = 0.005), while exhibiting a trend to improve ADFI (330g vs 364g, P = 0.080). Within dietary phase 3 (d 21–42), the inclusion of MCFA blend improved ADG (518g vs 581g, P = 0.024) and ADFI (719g vs 799g, P = 0.006). Overall (d 0–42), the inclusion of MCFA blend improved ADG (379g vs 438g, P = 0.007), ADFI (503g vs 0.562g, P = 0.009), and G:F (0.75 vs 0.78, P = 0.042), resulting in a 2 kg heavier pig (P = 0.043). In summary, the inclusion of a proprietary C8:C10 MCFA blend at 1.0% in nursery pig diets improved growth performance.

The aim of this study was to identify the reasons for hospitalization associated with abortion and pregnancy termination among women attending the Maternity Unit of IMIP, Recife, Brazil. In a case-control study, 230 women who were hospitalized consecutively between August 1994 and June 1995 due to causes related to pregnancy termination or abortion were chosen as cases. Four controls per case were selected randomly out of a total of 920 women who delivered at the same hospital. For each potential cause considered, the odds ratio (OR) and respective 95 per cent confidence interval (CI) were calculated. Multiple logistic regression analysis was then used to control for confounders. Among all potential causes studied, those that showed significant association with pregnancy termination or abortion were: being single, absence of emotional support from partner, being a working woman, literacy up to the fourth year of school, failure of contraceptive method employed, and experience of previous pregnancies, children, and abortions.
