In this article, we explore medical doctors’ moral experiences of being responsible for decisions on the lives and sometimes deaths of infants in a Danish Neonatal Intensive Care Unit (NICU). Drawing on fieldwork, we investigate how clinicians navigate the tension between exercising medical authority and enabling parental involvement in decisions. Introducing the term “careography”, we call attention to how the doctors steer this tension through care for the infant, parents, colleagues, and society in ways that help them overcome moral ambivalences. We suggest that “careography” holds analytical potential to bridge anthropological theories of power, experience, and care.  相似文献

Background

Hypospadias is a relatively common congenital malformation. Data on temporal trends in prevalence of hypospadias are conflicting. It is unclear whether changes of maternal age distribution over time are associated with changes in hypospadias prevalence.

Objective

To study changes in prevalence of hypospadias in Denmark during a 29-yr period and to investigate whether maternal age was associated with the prevalence of hypospadias.

Design, setting, and participants

Through Denmark's National Patient Registry, covering all Danish hospitals, we identified all boys diagnosed with hypospadias in Denmark. From the Danish Medical Birth Registry, we obtained information on maternal age and on the annual total number of live-born boys from 1977 to 2005.

Measurements

Prevalence of hypospadias at birth.

Results and limitations

Among 921 745 boys born alive from 1977 to 2005, we identified 3490 boys with hypospadias. The prevalence increased from 0.24% in 1977 to 0.52% in 2005, corresponding with an annual increase in prevalence of 2.40% (95% confidence interval: 1.94–2.86). The prevalence of hypospadias did not differ according to maternal age. The mean annual prevalence was 0.38% in sons of mothers aged ≤25 yr, 0.37% in sons of mothers aged 26–30 yr, 0.39% in sons of mothers aged 31–35 yr, and 0.39% in sons of mothers >35 yr.

Conclusions

The hypospadias prevalence was increasing in Denmark from 1977 to 2005. Increased maternal age did not explain this trend.  相似文献

Background: Patients with inflammatory bowel disease (IBD) and symptoms of irritable bowel syndrome (IBS) may be intolerant to fermentable carbohydrates (FODMAPs). The aim of this study was to test the feasibility of eliminating and subsequently reintroducing FODMAPs in patients with IBS symptoms as part of the IBD manifestation and to compare the severity of IBS symptoms and pain, bloating and quality of life (QoL). Methods: An eight-week randomised open-label FODMAP elimination with double-blinded, crossover provocations of FODMAP and placebo. Diet patients were on a low-FODMAP diet for eight weeks with blinded two-week provocations after two and six weeks. Questionnaires, blood and stool samples were collected. Results: Patient enrolment was challenging. Nineteen participants were included in the study. Eliminating low FODMAP for two weeks resulted in significant decreases in pain and bloating scores (p < 0.003), whereas there were no statistical differences in pain scores between diet patients and controls. Pain and bloating scores increased, returning to baseline levels after two weeks of double-blinded provocations with placebo, (p > 0.05). Conclusions: The results document the possibility of performing a randomised controlled study following the gold standard for testing food intolerance with blinding of the Low FODMAP diet. Recruitment of participants was challenging.  相似文献

Prochloraz is a commonly used fungicide that has shown multiple mechanisms of action in vitro. It antagonizes the androgen and the estrogen receptors, agonizes the Ah receptor, and inhibits aromatase activity. In vivo prochloraz acts antiandrogenically in the Hershberger assay by reducing weights of reproductive organs, affecting androgen-regulated gene expressions, and increasing luteinizing hormone (LH) levels. The purpose of this study was to investigate reproductive toxic effects after exposure during gestation and lactation to prochloraz alone and a mixture of five pesticides (deltamethrin, methiocarb, prochloraz, simazine, and tribenuron-methyl). Prochloraz (30 mg/kg/day) or the mixture (20 mg/kg/day) was dosed to pregnant Wistar dams from gestational day (GD) 7 until postnatal day (PND) 16. Some dams were taken for cesarean section at GD 21, and others were allowed to give birth. Results showed that prochloraz and the mixture significantly reduced plasma and testicular testosterone levels in GD 21 male fetuses, whereas testicular progesterone was increased. Gestational length was increased by prochloraz. Chemical analysis of the rat breast milk showed that prochloraz was transferred to the milk. In males a significant increase of nipple retention was found, and the bulbourethral gland weight was decreased, whereas other reproductive organs were unaffected. In addition cytochrome P450 (CYP)1A activities in livers were induced by prochloraz, possibly as a result of Ah receptor activation. Behavioral studies showed that the activity level and sweet preference of adult males were significantly increased. Overall these results strongly indicate that prochloraz feminizes the male offspring after perinatal exposure, and that these effects are due, at least in part, to diminished fetal steroidogenesis.  相似文献
