RESUMEN
Self-care improves health and well-being, yet many caregivers neglect it. During COVID-19, self-care courses for caregivers of veterans transitioned from in-person to virtual videoconferencing. The format remained the same with caregiver groups and a trainer. This observational study examined in-person and virtual caregivers' satisfaction with courses. Caregivers (1120 in-person, 962 virtual) could attend five courses before and following March 2020 transition to virtual. Evaluations (N = 1665) examined demographics, satisfaction, and utility. Characteristics were compared between in-person and virtual participants using chi-squared tests. Qualitative caregiver comments were compared. Half of the caregivers were over 60 years old; 49% had been caregivers at least 6 years. Caregivers were primarily women (91%) and spouses (75%), with more spouses virtually (p = 0.006) and more men in-person (p < 0.001). Both groups endorsed learning new information, planning to use it in caregiving and for themselves, increasing knowledge and skills, and having needs met. Caregiver comments revealed six types of benefits: new information, information review, positive effects, interaction, plans to act, and instructor qualities. Caregivers in virtual groups more often mentioned learning more information, being reminded of information, and planning to take further action; in-person caregivers more often mentioned interaction as a benefit. Caregivers were satisfied with and found benefit from in-person and virtual self-care courses. Although in-person courses allow for more social connection with others, virtual courses offer decreased travel costs for instructors and increased convenience and access for caregivers.
RESUMEN
Rotylenchulus reniformis is one of 10 described species of reniform nematodes and is considered the most economically significant pest within the genus, parasitizing a variety of important agricultural crops. Rotylenchulus reniformis collected from cotton fields in the Southeastern US were observed to have the nematode parasitic bacterium Pasteuria attached to their cuticles. Challenge with a Pasteuria-specific monoclonal antibody in live immuno-fluorescent assay (IFA) confirmed the discovery of Pasteuria infecting R. reniformis. Scanning and transmission electron microscopy were employed to observe endospore ultrastructure and sporogenesis within the host. Pasteuria were observed to infect and complete their life-cycle in juvenile, male and female R. reniformis. Molecular analysis using Pasteuria species-specific and degenerate primers for 16s rRNA and spoII, and subsequent phylogenetic assessment, placed the Pasteuria associated with R. reniformis in a distinct clade within established assemblages for the Pasteuria infecting phytopathogenic nematodes. A global phylogenetic assessment of Pasteuria 16s rDNA using the Neighbor-Joining method resulted in a clear branch with 100% boot-strap support that effectively partitioned the Pasteuria infecting phytopathogenic nematodes from the Pasteuria associated with bacterivorous nematodes. Phylogenetic analysis of the R. reniformis Pasteuria and Pasteuria spp. parasitizing a number of economically important plant parasitic nematodes revealed that Pasteuria with different host specificities are closely related and likely constitute biotypes of the same species. This suggests host preference, and thus effective differentiation and classification are most likely predicated by an influential virulence determinant(s) that has yet to be elucidated. Pasteuria Pr3 endospores produced by in vitro fermentation demonstrated efficacy as a commercial bionematicide to control R. reniformis on cotton in pot tests, when applied as a seed treatment and in a granular formulation. Population control was comparable to a seed-applied nematicide/insecticide (thiodicarb/imidacloprid) at a seed coating application rate of 1.0 x 10(8) spores/seed.
