Does splenectomy increase the number of circulating hematopoietic stem/progenitor cells in patients with hepatitis C virus-associated liver cirrhosis?
Our data suggest that the spleen plays an important role in modulating HSC dynamics in patients with HCV-associated chronic liver disease. Our results also imply that splenectomy may improve liver function in patients with LC.
Our results support the hypothesis that the general increase in breastfeeding in Switzerland since 1994 can be interpreted in part as a consequence of an increasing number of baby-friendly health facilities, whose clients breastfeed longer. Nevertheless, several alternative explanations for the longer breastfeeding duration for deliveries that occurred in baby-friendly hospitals can be discussed. In Switzerland, baby-friendly hospitals actively use their certification by UNICEF as a promotional asset. It is thus possible that differences in breastfeeding duration are attributable to the fact that mothers who intend to breastfeed longer would choose to give birth in a baby-friendly hospital and these mothers would be more willing to comply with the recommendations of the UNICEF guidelines. Even if this were the case, however, this selection bias would not explain the differences in breastfeeding duration between designated baby-friendly health facilities with higher compliance with the UNICEF guidelines and those with lower compliance. Especially this last point strongly supports a beneficial effect of the BFHI, because mothers do not know how well hospitals comply with the UNICEF program. The fact that breastfeeding rates have generally improved even in non-baby-friendly health facilities may be indirectly influenced by the BFHI; its publicity and training programs for health professionals have raised public awareness of the benefits of breastfeeding, and the number of professional lactation counselors has increased continuously. Breastfeeding prevalence and duration in Switzerland have improved in the past 10 years. Children born in a baby-friendly health facility are more likely to be breastfed for a longer time, particularly if the hospital shows high compliance with UNICEF guidelines. Therefore, the BFHI should be continued but should be extended to include monitoring for compliance, to promote the full effect of the BFHI.
