Premature and low birthweight infants pose particular challenges to health services in South Africa. While there is good evidence to demonstrate the benefits of kangaroo care in low birthweight infants, limited research has been conducted locally on the experiences of parents who provide kangaroo care to their preterm infants. This phenomenological study explores the lived experience of parents who provided their preterm infants with kangaroo care at a tertiary-level maternity centre in the Western Cape. In-depth interviews were conducted with six parents: four mothers and two fathers. Data was analysed using an adaptation of the approaches described by Colaizzi (1978:48-71) and Hycner (1985:280-294). To ensure trustworthiness, the trustworthiness criteria described by Guba and Lincoln (1989:242-243) were applied. Kangaroo care is a phased process, each phase bringing a unique set of experiences. The eight themes that emerged are described: unforeseen, unprepared and uncertain - the experience of birth; anxiety and barriers; an intimate connection; adjustments, roles and responsibilities; measuring success; a network of encouragement and support; living-in challenges; and living with the infant outside of hospital. Challenges facing health care providers are described and recommendations for information about kangaroo care and support for parents are made. Opsomming Vroeggebore babas en babas met ’n lae geboortegewig stel besondere uitdagings vir Suid-Afrikaanse gesondhiedsdienste. Daar bestaan goeie bewyse dat die kangaroesorgmetode voordelig is vir babas met ’n laegeboortegewig, dog is minimale plaaslike navorsing gedoen oor die ondervindinge van ouers wat hierdie metode gebruik om vir hul vroeggebore babas te sorg. Hierdie fenomenologiese studie verken die geleefde ervaringe van ouers wat vir hulle vroeggebore babas deur middel van die kangaroesorgmetode in ’n tersiêre kraamsentrum in die Weskaap gesorg het. Data is ingesamel deur in-diepte onderhoude met ses ouers te voer: vier moeders and twee vaders van vroeggebore babas. Data is ontleed volgens ’n verwerking van die metodes soos deur Colaizzi (1978:48-71) en Hycner (1985:280-294) beskryf. Om betroubaarheid te verseker, is die betroubaarheidskriteria van Guba en Lincoln (1989:242-243) toegepas. Kangaroesorg is ’n geleidelike proses; elke fase lei tot ‘n unieke stel ondervindinge. Agt temas is uit die data geïdentifiseer: Onverwags, onvoorbereid en onseker - die geboorte-ervaring; angstigheid and hindernisse; ’n intieme verband; aanpassings, rolle en verantwoordelikhede; die meting van sukses; ’n netwerk van aanmoediging en ondersteuning; die uitdagings van binne die hospitaal leef; saamleef met die baba buite die hospital. Uitdagings wat gesondheidspersonnel te voorstaan kom en aanbevelings oor inligting met betrekking tot kangaroesorg en ondersteuning aan ouers word voorgestel.

The findings suggest that patients with progressive/fibrotic pulmonary sarcoidosis have intense immune activity related to host defense in their lungs, with processes more similar to HP than IPF. The study also demonstrates that transbronchial lung biopsy samples can provide good-quality RNA for gene expression profiling, supporting its potential use as a prognostic classifier for pulmonary sarcoidosis.

Rare inactivating mutations in BRCA1, BRCA2, ATM, TP53 and CHEK2 confer relative risks for breast cancer between about 2 and more than 10, but more common variants in these genes are generally considered of little or no clinical significance. Under the polygenic model for breast cancer carriers of multiple low-penetrance alleles are at high risk, but few such alleles have been reliably identified. We analysed 1037 potentially functional single nucleotide polymorphisms (SNPs) in candidate cancer genes in 473 women with two primary breast cancers and 2463 controls. Twenty-five of these SNPs were in BRCA1, BRCA2, ATM, TP53 and CHEK2. Among the 1037 SNPs there were a few significant findings, but hardly more than would be expected in this large experiment. There was, however, a significant trend in risk with increasing numbers of variant alleles for the 25 SNPs in BRCA1, BRCA2, ATM, TP53 and CHEK2 (P(trend) = 0.005). For the 21 of these with minor allele frequency <10% this trend was highly significant (P(trend) = 0.00004, odds ratio for 3 or more SNPs = 2.90, 95% CI 1.69-4.97). The individual effects of most of these risk alleles were undetectably small even in this well powered study, but the risk conferred by multiple variants is readily detectable and makes a substantial contribution to susceptibility. A risk score incorporating a suitably weighted sum of all potentially functional variants in these and a few other candidate genes may provide clinically useful identification of women at high genetic risk.
