Social theory and infant feeding
Clinicians, public health advisors, nutritionists and others have been attempting to increase breastfeeding rates for the last few decades, with varying degrees of success. We need social science researchers to help us understand the role of infant feeding in the family. Some researchers in the area of food and nutrition have found Pierre Bourdieu's theoretical framework helpful. In this editorial, I introduce some of Bourdieu's ideas and suggest researchers interested in infant feeding should consider testing these theories
Infant feeding, poverty and human development
The relationship between poverty and human development touches on a central aim of the International Breastfeeding Journal's editorial policy which is to support and protect the health and wellbeing of all infants through the promotion of breastfeeding. It is proposed that exclusive breastfeeding for 6 months, followed by continued breastfeeding to 12 months, could prevent 1,301,000 deaths or 13% of all child deaths under 5 years in a hypothetical year. Although there is a conventional wisdom that poverty 'protects' breastfeeding in developing countries, poverty actually threatens breastfeeding, both directly and indirectly. In the light of increasingly aggressive marketing behaviour of the infant formula manufacturers and the need to protect the breastfeeding rights of working women, urgent action is required to ensure the principles and aim of the International Code of Breastmilk Substitutes, and subsequent relevant resolutions of the World Health Assembly, are implemented. If global disparities in infant health and development are to be significantly reduced, gender inequities associated with reduced access to education and inadequate nutrition for girls need to be addressed. Improving women's physical and mental health will lead to better developmental outcomes for their children
Policy on infant formula industry funding, support or sponsorship of articles submitted for publication
Despite current scientific evidence that artificial feeding is a harmful practice, unquestioned acceptance of breastfeeding as the normal or "default" method of infant feeding remains elusive in the industrialised world. Throughout the developing world the profound consequences of the aggressive marketing strategies of the infant formula industry since the end of the Second World War is well known. A key objective of the International Breastfeeding Journal is to promote breastfeeding through addressing issues that encourage breastfeeding initiation, duration and effective management. Informing this aim is the recognition of artificial feeding as a harmful practice that places infant health at risk. From this perspective it would be unethical for this journal to accept for publication any manuscript that has received funding, sponsorship or any other means of support from infant formula manufacturers. This stance is consistent with the journal's aim of supporting, protecting and promoting breastfeeding. It will also contribute to the promotion of a breastfeeding culture
Health professionals' advice for breastfeeding problems: Not good enough!
Jane Scott and colleagues have recently published a paper in the International Breastfeeding Journal showing that health professionals are still giving harmful advice to women with mastitis. We see the management of mastitis as an illustration of health professionals' management of wider breastfeeding issues. If health professionals don't know how to manage this common problem, how can they be expected to manage less common conditions such as a breast abscess or nipple/breast candidiasis? There is an urgent need for more clinical research into breastfeeding problems and to improve the education of health professionals to enable them to promote breastfeeding and support breastfeeding women

Understanding Why Older Adults With Type 2 Diabetes Join Diabetes Online Communities: Semantic Network Analyses.
BackgroundAs individuals age, chronic health difficulties may disrupt physical and social well-being. Individuals can turn to online communities to interact with similar peers, which may help buffer negative effects resulting from health difficulties.ObjectiveThis study investigated the reasons that older adults join a diabetes online community to better understand the specific resources that are being sought.MethodsWe used semantic network analyses to categorize the reasons participants provided for joining a community during the sign-up process.ResultsThe most frequent reasons for joining were to seek information about their health condition, to help with self-management of health difficulties, for feelings of informational and social support, and for having a community with whom to share. Women were more likely to go online for sharing and companionship as well as for information and social support reasons, whereas men were more likely to go online for general information and self-management reasons.ConclusionsThis study shows the reasons older adults seek to join a diabetes online community: for increased information and support regarding chronic health difficulties. Practitioners may want to consider ways to promote access to online communities among their older patients as a source of health information and a resource to provide a sense of community
Maternal bodies and medicines: a commentary on risk and decision-making of pregnant and breastfeeding women and health professionals
<p>Abstract</p> <p>Background</p> <p>The perceived risk/benefit balance of prescribed and over-the-counter (OTC) medicine, as well as complementary therapies, will significantly impact on an individual’s decision-making to use medicine. For women who are pregnant or breastfeeding, this weighing of risks and benefits becomes immensely more complex because they are considering the effect on two bodies rather than one. Indeed the balance may lie in opposite directions for the mother and baby/fetus. The aim of this paper is to generate a discussion that focuses on the complexity around risk, responsibility and decision-making of medicine use by pregnant and breastfeeding women. We will also consider the competing discourses that pregnant and breastfeeding women encounter when making decisions about medicine.</p> <p>Discussion</p> <p>Women rely not only on biomedical information and the expert knowledge of their health care professionals but on their own experiences and cultural understandings as well. When making decisions about medicines, pregnant and breastfeeding women are influenced by their families, partners and their cultural societal norms and expectations. Pregnant and breastfeeding women are influenced by a number of competing discourses. “Good” mothers should manage and avoid any risks, thereby protecting their babies from harm and put their children’s needs before their own – they should not allow toxins to enter the body. On the other hand, “responsible” women take and act on medical advice – they should take the medicine as directed by their health professional. This is the inherent conflict in medicine use for maternal bodies.</p> <p>Summary</p> <p>The increased complexity involved when one body’s actions impact the body of another – as in the pregnant and lactating body – has received little acknowledgment. We consider possibilities for future research and methodologies. We argue that considering the complexity of issues for maternal bodies can improve our understanding of risk and public health education.</p
Self-assembling nanoparticles containing dexamethasone as a novel therapy in allergic airways inflammation.
Nanocarriers can deliver a wide variety of drugs, target them to sites of interest, and protect them from degradation and inactivation by the body. They have the capacity to improve drug action and decrease undesirable systemic effects. We have previously developed a well-defined non-toxic PEG-dendritic block telodendrimer for successful delivery of chemotherapeutics agents and, in these studies, we apply this technology for therapeutic development in asthma. In these proof-of-concept experiments, we hypothesized that dexamethasone contained in self-assembling nanoparticles (Dex-NP) and delivered systemically would target the lung and decrease allergic lung inflammation and airways hyper-responsiveness to a greater degree than equivalent doses of dexamethasone (Dex) alone. We found that ovalbumin (Ova)-exposed mice treated with Dex-NP had significantly fewer total cells (2.78 ± 0.44 × 10(5) (n = 18) vs. 5.98 ± 1.3 × 10(5) (n = 13), P<0.05) and eosinophils (1.09 ± 0.28 × 10(5) (n = 18) vs. 2.94 ± 0.6 × 10(5) (n = 12), p<0.05) in the lung lavage than Ova-exposed mice alone. Also, lower levels of the inflammatory cytokines IL-4 (3.43 ± 1.2 (n = 11) vs. 8.56 ± 2.1 (n = 8) pg/ml, p<0.05) and MCP-1 (13.1 ± 3.6 (n = 8) vs. 28.8 ± 8.7 (n = 10) pg/ml, p<0.05) were found in lungs of the Dex-NP compared to control, and they were not lower in the Dex alone group. In addition, respiratory system resistance was lower in the Dex-NP compared to the other Ova-exposed groups suggesting a better therapeutic effect on airways hyperresponsiveness. Taken together, these findings from early-stage drug development studies suggest that the encapsulation and protection of anti-inflammatory agents such as corticosteroids in nanoparticle formulations can improve efficacy. Further development of novel drugs in nanoparticles is warranted to explore potential treatments for chronic inflammatory diseases such as asthma
EVALUATION OF REGENERATIVE THERAPY USING CELL SHEET THROUGH CEMENTUM PROTEIN-1 EXPRESSION ON MACACA NEMESTRINA
Objective: The main objective of periodontal therapy is tissue regeneration. Previous studies have identified the potential of mesenchymal stem cells to improve major periodontal defect reconstruction in bone tissue engineering. Cell sheet technology (CST), in which a cell culture is obtained from a material coated with a temperature-sensitive substrate, has been developed for the reconstruction of various tissues, including periodontal tissue. Cementum protein-1 (CEMP-1) is a 50-kDa protein that plays a crucial role in cementogenesis by enhancing the combining of cells formed by cell cementoblast. Evaluate periodontal tissue regeneration with CST, and the application of chitosan, chitosan cell sheet or arginineglycineaspartic acid (RGD)-modified chitosan cell sheet on Macaca nemestrina one-wall defect model.Methods: The CEMP-1 was analyzed expression in a sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) gel electrophoresis assay.Results: CEMP-1 expression in gingival crevicular fluid was observed using the SDS-PAGE method every week for 3Â weeks. Protein band expressions on SDS-PAGE gel were identified at around 50Â kDa with different thicknesses between groups. The chitosan, chitosan cell sheet, and RGD-modified chitosan cell sheet groups showed protein bands of CEMP-1 between 50 and 70Â kDa at weeks 1, 2, and 3; weeks 2 and 3; and weeks 1 and 2, respectively.Conclusion: Our results demonstrated that the application of chitosan and RGD-modified chitosan cell sheets could enhance bone regeneration, as evidenced by CEMP-1 protein expression levels
Reliability of the Hazelbaker Assessment Tool for Lingual Frenulum Function
BACKGROUND: About 3% of infants are born with a tongue-tie which may lead to breastfeeding problems such as ineffective latch, painful attachment or poor weight gain. The Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) has been developed to give a quantitative assessment of the tongue-tie and recommendation about frenotomy (release of the frenulum). The aim of this study was to assess the inter-rater reliability of the HATLFF. METHODS: Fifty-eight infants referred to the Breastfeeding Education and Support Services (BESS) at The Royal Women's Hospital for assessment of tongue-tie and 25 control infants were assessed by two clinicians independently. RESULTS: The Appearance items received kappas between about 0.4 to 0.6, which represents "moderate" reliability. The first three Function items (lateralization, lift and extension of tongue) had kappa values over 0.65 which indicates "substantial" agreement. The four Function items relating to infant sucking (spread, cupping, peristalsis and snapback) received low kappa values with insignificant p values. There was 96% agreement between the two assessors on the recommendation for frenotomy (kappa 0.92, excellent agreement). The study found that the Function Score can be more simply assessed using only the first three function items (ie not scoring the sucking items), with a cut-off of ≤4 for recommendation of frenotomy. CONCLUSION: We found that the HATLFF has a high reliability in a study of infants with tongue-tie and control infant
