Little is known of the impact of having a sibling with CHD. Available literature documents negative impact of having a sibling with other chronic conditions. This literature review considers empirical evidence investigating the impact of having a sibling with CHD. Twelve databases were searched, and 202 articles retrieved. Eleven articles met the inclusion criteria and were subject to data extraction, quality appraisal, and narrative synthesis. Three themes emerged changes in normal life, impact on siblings, and factors affecting the extent of impact on siblings. Only one intervention study was identified, 5 of 10 studies were conducted over 20 years ago, and only 4 studies included children as participants. Evidence suggests siblings of children with CHD experience adverse life changes which lead to negative impacts in several domains. Evidence is inconclusive regarding mitigating factors of these impacts. Further research is needed to understand the experiences of being a sibling of a child with CHD.Aim To support pharmacokinetic studies and therapeutic monitoring of darunavir (DRV), a highly sensitive ELISA was developed for the determination of DRV in plasma samples at picogram levels. Results The assay LOD and LOQ were 15 and 30 pg ml-1, respectively. The working range of the assay was 20-2000 pg ml-1. Analytical recoveries of DRV from spiked plasma were in the ranges of 98.4-113.0 and 86.0-99.1% for intra-assay and inter-assay runs, respectively. The precision of the assay was satisfactory. Conclusion The ELISA is characterized by high throughput and it is expected to significantly contribute to routine analysis of DRV in its pharmacokinetic studies and therapeutic monitoring.This study ai
