Abstract: Background: Both peer and professional support have been identified as important to the success of breastfeeding. The aim of this metasynthesis was to examine women’s perceptions and experiences of breastfeeding support, either professional or peer, to illuminate the components of support that they deemed “supportive.” Methods: The metasynthesis included studies of both formal or “created” peer and professional support for breastfeeding women but excluded studies of family or informal support. Qualitative studies were included as well as large‐scale surveys if they reported the analysis of qualitative data gathered through open‐ended responses. Primiparas and multiparas who initiated breastfeeding were included. Studies published in English, in peer‐reviewed journals, and undertaken between January 1990 and December 2007 were included. After assessment for relevance and quality, 31 studies were included. Meta‐ethnographic methods were used to identify categories and themes. Results: The metasynthesis resulted in four categories comprising 20 themes. The synthesis indicated that support for breastfeeding occurred along a continuum from authentic presence at one end, perceived as effective support, to disconnected encounters at the other, perceived as ineffective or even discouraging and counterproductive. A facilitative approach versus a reductionist approach was identified as contrasting styles of support that women experienced as helpful or unhelpful. Conclusions: The findings emphasize the importance of person‐centered communication skills and of relationships in supporting a woman to breastfeed. Organizational systems and services that facilitate continuity of caregiver, for example continuity of midwifery care or peer support models, are more likely to facilitate an authentic presence, involving supportive care and a trusting relationship with professionals.

Abstract: Background: The World Health Organization (WHO) developed the Baby‐Friendly Hospital Initiative to improve hospital maternity care practices that support breastfeeding. In Hong Kong, although no hospitals have yet received the Baby‐Friendly status, efforts have been made to improve breastfeeding support. The aim of this study was to examine the impact of Baby‐Friendly hospital practices on breastfeeding duration. Methods: A sample of 1,242 breastfeeding mother‐infant pairs was recruited from four public hospitals in Hong Kong and followed up prospectively for up to 12 months. The primary outcome variable was defined as breastfeeding for 8 weeks or less. Predictor variables included six Baby‐Friendly practices: breastfeeding initiation within 1 hour of birth, exclusive breastfeeding while in hospital, rooming‐in, breastfeeding on demand, no pacifiers or artificial nipples, and information on breastfeeding support groups provided on discharge. Results: Only 46.6 percent of women breastfed for more than 8 weeks, and only 4.8 percent of mothers experienced all six Baby‐Friendly practices. After controlling for all other Baby‐Friendly practices and possible confounding variables, exclusive breastfeeding while in hospital was protective against early breastfeeding cessation (OR: 0.61; 95% CI: 0.42–0.88). Compared with mothers who experienced all six Baby‐Friendly practices, those who experienced one or fewer Baby‐Friendly practices were almost three times more likely to discontinue breastfeeding (OR: 3.13; 95% CI: 1.41–6.95). Conclusions: Greater exposure to Baby‐Friendly practices would substantially increase new mothers’ chances of breastfeeding beyond 8 weeks postpartum. To further improve maternity care practices in hospitals, institutional and administrative support are required to ensure all mothers receive adequate breastfeeding support in accordance with WHO guidelines.

Abstract: Background: Breastfeeding is the optimal feeding method for human infants. In the United Kingdom some women do not initiate breastfeeding, and many commence formula milk feeding after a brief period of breastfeeding. Infant feeding perceptions may develop early in life, and this research aimed to explore infant feeding awareness among primary school children as a first step toward informing appropriate health education interventions. Method: Fifty‐six children aged 5/6, 7/8, and 10/11 years were recruited from three schools in southern England. Children were shown a series of drawings, and were read a story about a hungry newborn baby. A creative method, “draw, write and tell,” was developed for this research. Children were asked to finish the story, showing how they thought the baby might be fed. They were given the opportunity to verbally interpret their work. A constant comparison method was used to analyze the data. Results: Children were aware of formula milk, breastfeeding, and solid foods. Formula milk feeding was referred to more frequently than breastfeeding. Some children combined feeding methods. Children appeared to have gained their awareness in various settings. Conclusions: Children have a range of perceptions around infant feeding. They appear receptive to new ideas on the subject while of primary school age. An opportunity for education in primary schools arises to present breastfeeding to children as a normal way to feed a baby, but it is vital that education is evidence based and any interventions are evaluated.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer‐related death worldwide. Despite increasing treatment options for this disease, prognosis remains poor. CRIPTO (TDGF1) protein is expressed at high levels in several human tumours and promotes oncogenic phenotype. Its expression has been correlated to poor prognosis in HCC. In this study, we aimed to elucidate the basis for the effects of CRIPTO in HCC. We investigated CRIPTO expression levels in three cohorts of clinical cirrhotic and HCC specimens. We addressed the role of CRIPTO in hepatic tumourigenesis using Cre‐loxP‐controlled lentiviral vectors expressing CRIPTO in cell line‐derived xenografts. Responses to standard treatments (sorafenib, doxorubicin) were assessed directly on xenograft‐derived ex vivo tumour slices. CRIPTO‐overexpressing patient‐derived xenografts were established and used for ex vivo drug response assays. The effects of sorafenib and doxorubicin treatment in combination with a CRIPTO pathway inhibitor were tested in ex vivo cultures of xenograft models and 3D cultures. CRIPTO protein was found highly expressed in human cirrhosis and hepatocellular carcinoma specimens but not in those of healthy participants. Stable overexpression of CRIPTO in human HepG2 cells caused epithelial‐to‐mesenchymal transition, increased expression of cancer stem cell markers, and enhanced cell proliferation and migration. HepG2‐CRIPTO cells formed tumours when injected into immune‐compromised mice, whereas HepG2 cells lacking stable CRIPTO overexpression did not. High‐level CRIPTO expression in xenograft models was associated with resistance to sorafenib, which could be modulated using a CRIPTO pathway inhibitor in ex vivo tumour slices. Our data suggest that a subgroup of CRIPTO‐expressing HCC patients may benefit from a combinatorial treatment scheme and that sorafenib resistance may be circumvented by inhibition of the CRIPTO pathway.

Objective

to assess the effects of transcutaneous electrical nerve stimulation (TENS) for pain relief in labour.

Search methods

studies were identified from a search of the Cochrane Pregnancy and Childbirth Group’s Trials Register (November 2008).

Selection criteria

randomised controlled trials comparing women receiving TENS for pain relief in labour vs routine care or placebo devices. All types of TENS machines were included.

Data collection and analysis

two review authors assessed all trials identified by the search strategy, carried out data extraction and assessed risk of bias.

Results

14 studies including 1256 women were included: 11 examined TENS applied to the back, two to acupuncture points and one to the cranium. Overall, there was little difference in satisfaction with pain relief or in pain ratings between TENS and control groups, although women receiving TENS to acupuncture points were less likely to report severe pain (risk ratio 0.41, 95% confidence interval 0.32–0.55). The majority of women using TENS would use it again in a future labour. There was no evidence that TENS had any impact on interventions and outcomes in labour. There was little information on outcomes for mothers and infants. No adverse events were reported.

Conclusions

there is only limited evidence that TENS reduces pain in labour and it does not seem to have any impact on other outcomes for mothers or infants. The use of TENS at home in early labour has not been evaluated. Although the guidelines of the National Institute for Health and Clinical Excellence recommend that TENS should not be offered to women in labour, women appear to be choosing it and midwives are supporting them in their choice. Given the absence of adverse effects and the limited evidence base, it seems unreasonable to deny women that choice. More robust studies of effectiveness are needed.  相似文献

Background

Gloriosa superba produces an array of alkaloids including colchicine, a compound of interest in the treatment of various diseases. The tuber of Gloriosa superba is a rich source of colchicine which has shown anti-gout, anti-inflammatory, and anti-tumor activity. However, this promising compound remains expensive and Gloriosa superba is such a good source in global scale. Increase in yield of naturally occurring colchicine is an important area of investigation.

Materials and Methods

The effects of inoculation by four arbuscular mycorrhizal (AM), fungi, Glomus mossae, Glomus fasciculatum, Gigaspora margarita and Gigaspora gilmorei either alone or supplemented with P-fertilizer, on colchicine concentration in Gloriosa superba were studied. The concentration of colchicine was determined by high-performance thin layer chromatography.

Results

The four fungi significantly increased concentration of colchicine in the herb. Although there was significant increase in concentration of colchicine in non-mycorrhizal P-fertilized plants as compared to control, the extent of the increase was less compared to mycorrhizal plants grown with or without P-fertilization. This suggests that the increase in colchicine concentration may not be entirely attributed to enhanced P-nutrition and improved growth. Among the four AM fungi Glomus mossae was found to be best. The total colchicine content of plant (mg / plant) was significantly high in plants inoculated with Glomus mossae and 25 mg kg−1phosphorus fertilizer (348.9 mg /plant) while the control contain least colchicine (177.87 mg / plant).

Conclusion

The study suggests a potential role of AM fungi in improving the concentration of colchicine in Gloriosa superba tuber.  相似文献

Objective

infants of women with diabetes in pregnancy are at increased risk of hypoglycaemia. If the infant's blood glucose is low and the mother is unable to breast feed/provide sufficient expressed breast milk, infants are often given formula. Some hospitals encourage women with diabetes to express breast milk before birth. However, there is limited evidence for this practice, including its impact on labour and birth, e.g. causing premature birth may be a concern. A pilot study was undertaken to establish the feasibility of conducting an adequately powered randomised controlled trial to evaluate this practice.

Design

consecutive eligible women with pre-existing or gestational diabetes (requiring insulin), planning to breast feed and attending the study hospital were offered participation. Inclusion criteria: 34-36 weeks of gestation; singleton pregnancy; cephalic presentation; and able to speak, read and write in English. Exclusion criteria: history of spontaneous preterm birth, antepartum haemorrhage, placenta praevia and suspected fetal compromise. Women were encouraged to express colostrum twice a day from 36 weeks of gestation, and advised how to store the colostrum, which was frozen for their infant's use after birth. They were asked to keep a diary documenting their expressing. Data: demographic questionnaire, telephone interview at six and 12 weeks postpartum and medical record data.

Setting

a public, tertiary, women's hospital in Melbourne, Australia.

Participants

43 women with diabetes in pregnancy (requiring insulin).

Findings

cardiotocographs were undertaken after the first expressing episode and none of the infants showed any sign of fetal compromise. Forty per cent of infants received formula in the 24 hours postpartum. The proportion of infants receiving any breast milk at six weeks was 90%, and this decreased to 75% at 12 weeks. No women showed evidence of hypoglycaemia post expressing. The intervention was positively received by most women; 95% said that they would express antenatally again if the practice proved to be beneficial. The amount of colostrum varied according to the number of expressions, the length of time in the study and the time spent expressing, with a median of 14 days expressing and 39.6 ml of colostrum obtained.

Key conclusions

the small number of women in this pilot was not an adequate number to examine safety or efficacy, but this study does provide evidence that it would be feasible and desirable to conduct a randomised controlled trial of antenatal milk expressing for women with diabetes requiring insulin in pregnancy.

Implications for practice

it is important that this widespread practice undergoes rigorous evaluation to assess both efficacy and safety. Until such evidence is available, the authors suggest that the routine encouragement of antenatal milk expressing in women with diabetes in pregnancy should cease.  相似文献
