Characterization of eleven polymorphic microsatellite markers for leafhoppers of the genus Aphrodes (Hemiptera: Cicadellidae)

Eleven microsatellite markers were developed for the leafhoppers of the genus Aphrodes using shotgun pyrosequencing and will be used to study the genetic diversity, population structure and gene flow within and between species in this genus in order to assess their conservation status. The number of alleles per locus ranged from 3 to 10, while observed and expected heterozygosity values varied from 0.421–1.000 to 0.542–0.876, respectively. Cross-species amplification was successful among the four congeners.     

A conceptual definition of quality of life with a left ventricular assist device: Results from a qualitative study

Objective

To develop a conceptual definition of quality of life (QoL) with a left ventricular assist device (LVAD).

Background

Conceptual and operational definitions of QoL with an LVAD are lacking.

Methods

A grounded theory method was used. Adult, outpatient LVAD recipients (n = 11) participated twice in individual or paired interviews.

Results

A conceptual definition of QoL while living with an LVAD was established as: “Being well enough to do and enjoy day-to-day activities that are important to me.” Participants described 5 important life domains consistent with QoL literature: physical, emotional, social, cognitive, and spiritual/meaning. However, participants identified unique concerns not addressed by generic or heart failure disease specific measures typically used in the LVAD population.

Conclusion

Existing generic and heart-failure specific QoL measures are not adequate for understanding QoL among LVAD patients. Cognition and spiritual/meaning domains were significant; these need inclusion for comprehensive QoL assessment in the LVAD population.
