“They call our children „Nevirapine Babies‟”: A Qualitative Study about Exclusive Breastfeeding among HIV Positive Mothers in Malawi

Infant feeding is estimated to be responsible for 5%-20% of the burden of HIV transmission from mother to child. HIV positive women who cannot afford safe formula feeding are advised to practise exclusive breastfeeding (EBF) followed by prompt weaning. We conducted a qualitative study using observations and in-depth individual interviews to explore patterns of EBF as well as which factors motivate or hinder women to practice EBF. HIV positive women who intended to practice EBF from urban Malawi were purposively selected and interviewed. All women were well informed and had high knowledge on HIV as well as on EBF but much less knowledge on basic facts about breastfeeding. Despite their inten-tions less than half of the interviewed women managed to practice EBF and the barriers were explained by perceived lack of milk, lack of control over the feeding situation, felt and enacted stigma as well as poor counselling. Women who succeeded were older, had the explicit support of their husband and lived without the presence of their mother-in-law. Weaning at the age of 6 months was reported to be as difficult for the women as EBF. Intention itself is not a sufficient determinant of successful EBF unless a number of enabling factors come together. Prolonged breastfeeding is the cultural norm in Malawi and programs must be sensitive to social expectations to mothers and involve mothers-in-law and fathers in counselling of mothers who intend to practice EBF (Afr. J. Reprod. Health 2010; 14[3]: 213-222).Key words: Breastfeeding, exclusive breastfeeding, weaning, HIV/AIDS, Malawi

CD6 and Syntaxin Binding Protein 6 Variants and Response to Tumor Necrosis Factor Alpha Inhibitors in Danish Patients with Rheumatoid Arthritis

<div><h3>Background</h3><p>TNFα inhibitor therapy has greatly improved the treatment of patients with rheumatoid arthritis, however at least 30% do not respond. We aimed to investigate insertions and deletions (INDELS) associated with response to TNFα inhibitors in patients with rheumatoid arthritis (RA).</p> <h3>Methodology and Principal Findings</h3><p>In the DANBIO Registry we identified 237 TNFα inhibitor naïve patients with RA (81% women; median age 56 years; disease duration 6 years) who initiated treatment with infliximab (n = 160), adalimumab (n = 56) or etanercept (n = 21) between 1999 and 2008 according to national treatment guidelines. Clinical response was assessed at week 26 using EULAR response criteria. Based on literature, we selected 213 INDELS potentially related to RA and treatment response using the GeneVa® (Compugen) <em>in silico</em> database of 350,000 genetic variations in the human genome. Genomic segments were amplified by polymerase chain reaction (PCR), and genotyped by Sanger sequencing or fragment analysis. We tested the association between genotypes and EULAR good response versus no response, and EULAR good response versus moderate/no response using Fisher’s exact test. At baseline the median DAS28 was 5.1. At week 26, 68 (29%) patients were EULAR good responders, while 81 (34%) and 88 (37%) patients were moderate and non-responders, respectively. A 19 base pair insertion within the CD6 gene was associated with EULAR good response vs. no response (OR = 4.43, 95% CI: 1.99–10.09, p = 7.211×10⁻⁵) and with EULAR good response vs. moderate/no response (OR = 4.54, 95% CI: 2.29–8.99, p = 3.336×10⁻⁶). A microsatellite within the syntaxin binding protein 6 (STXBP6) was associated with EULAR good response vs. no response (OR = 4.01, 95% CI: 1.92–8.49, p = 5.067×10⁻⁵).</p> <h3>Conclusion</h3><p>Genetic variations within CD6 and STXBP6 may influence response to TNFα inhibitors in patients with RA.</p> </div

Children at Risk: A Study of the Psychosocial Impact of HIV on Orphans and other Vulnerable Children in Benin

This paper describes the effect of parental HIV on the life of children in Benin. A total of 2,043 children aged from 10 to 16 were surveyed on health, diet, violence, school attendance and psychosocial state. The results indicate that, while Beninese children who have had a parent living with HIV are not necessarily subjected to different economic and material conditions than those who have not, they do experience a much greater lack of psychosocial support. In contrast to children whose parents are not known to have HIV, these affected children areless prone to general illness (OR=0.69, 95 per cent CI 0.55-0.86). However, when they are sick, HIV-affected children are significantly more likely to undertake self-treatment (OR=1.38; 95 per cent CI 1.04-1.86) and more likely to work (OR=1.65, 95 per cent CI 1.04-2.60). They are also offered fewer meals than unaffectedchildren (OR=1.94; 95 per cent CI 1.52-2.47). With respect to psychosocial factors, the data suggest that children who have had a parent with HIV have significantly higher levels of psychological distress than those who have not. Governments and civil society organisations need to address not only the material deprivation, especially hunger, of children thus affected by HIV, but also theirneed for social services

Evolution and diversification of Pseudomonas aeruginosa in the paranasal sinuses of cystic fibrosis children have implications for chronic lung infection

The opportunistic pathogen Pseudomonas aeruginosa is a frequent colonizer of the airways of patients suffering from cystic fibrosis (CF). Depending on early treatment regimens, the colonization will, with high probability, develop into chronic infections sooner or later, and it is important to establish under which conditions the switch to chronic infection takes place. In association with a recently established sinus surgery treatment program for CF patients at the Copenhagen CF Center, colonization of the paranasal sinuses with P. aeruginosa has been investigated, paralleled by sampling of sputum from the same patients. On the basis of genotyping and phenotypic characterization including transcription profiling, the diversity of the P. aeruginosa populations in the sinuses and the lower airways was investigated and compared. The observations made from several children show that the paranasal sinuses constitute an important niche for the colonizing bacteria in many patients. The paranasal sinuses often harbor distinct bacterial subpopulations, and in the early colonization phases there seems to be a migration from the sinuses to the lower airways, suggesting that independent adaptation and evolution take place in the sinuses. Importantly, before the onset of chronic lung infection, lineages with mutations conferring a large fitness benefit in CF airways such as mucA and lasR as well as small colony variants and antibiotic-resistant clones are part of the sinus populations. Thus, the paranasal sinuses potentially constitute a protected niche of adapted clones of P. aeruginosa, which can intermittently seed the lungs and pave the way for subsequent chronic lung infections
