X-chromosomal STRs in aDNA kinship analysis.

The analysis of ancient DNA (aDNA) from human skeletal remains can provide useful insights when investigating archaeological finds. One popular application of aDNA is to examine genealogical relationships between individuals recovered at the same archaeological site. For the reconstruction of genealogical relationships, several genetic markers are commonly used: autosomal STRs, mitochondrial lineages (based on SNP-analysis) and Y-chromosomal haplotypes (based on Y-STR-analysis). In this paper, we present the additional opportunities that X-STRs provide in aDNA kinship reconstruction, especially in deficiency cases and for the examination of father-daughter relationships. Possible applications are demonstrated on a range of different kinship reconstructions: confirmation of half-siblingship in the Lichtenstein cave (Germany), exclusion of two potential father-daughter relationships in Goslar (Germany), investigation of three siblingships in Boilstädt (Germany) as well as the confirmation of a father-daughter relationship in Stolpe (Germany). This study shows that the analysis of X-STRs can contribute to the investigation of relationship constellations otherwise difficult to approach (e.g. father-daughter relationships) and that X-STRs are useful to support and complement autosomal STRs, mtDNA and Y-STR data.

Spiritual Care in Nursing Practice in Veteran Health Care.

Spiritual care is important in nursing practice, and spiritual well-being and spiritual care are associated with better health. Military veterans, a unique patient population, want spiritual care to cope with chronic conditions. It is unclear whether spiritual care is provided in veteran health care in the United States. This study used a qualitative descriptive method, guided by the Spiritual Care in Nursing Practice (SCNiP) theory, to describe spiritual care in nursing practice and facilitators/barriers in veteran health care. Individual interviews were conducted with 39 registered nurses (RNs) at a U.S. veteran health system. Findings were consistent with the SCNiP theory but revealed additional categorical attributes and processes as it applied to veteran health care. Facilitators that promoted spiritual care include nurse professionalism, collegial support, and available spiritual resources. Barriers included lack of time, task-oriented culture, unclear knowledge of accessing resources, and unclear organization policy in providing spiritual care. Findings further refined the theory.
