Effects of Staff Training on Nursing Home Residents’ End-Of-Life Care: A Randomized Controlled Trial

ObjectivesThis trial examines the effects of end-of-life training on long-term care facility (LTCF) residents' health-related quality of life (HRQoL) and use and costs of hospital services.DesignA single-blind, cluster randomized (at facility level) controlled trial (RCT). Our training intervention included 4 small-group 4-hour educational sessions on the principles of palliative and end-of-life care (advance care planning, adverse effects of hospitalizations, symptom management, communication, supporting proxies, challenging situations). Training was provided to all members of staff. Education was based on constructive learning methods and included resident cases, role-plays, and small-group discussions.Setting and participantsWe recruited 324 residents with possible need for end-of-life care due to advanced illness from 20 LTCF wards in Helsinki.MethodsPrimary outcome measures were HRQoL and hospital inpatient days per person-year during a 2-year follow-up. Secondary outcomes were number of emergency department visits and cost of all hospital services.ResultsHRQoL according to the 15-Dimensional Health-Related Quality-of-Life Instrument declined in both groups, and no difference was present in the changes between the groups (P for group .75, adjusted for age, sex, do-not-resuscitate orders, need for help, and clustering). Neither the number of hospital inpatient days (1.87 vs 0.81 per person-year) nor the number of emergency department visits differed significantly between intervention and control groups (P for group .41). The total hospital costs were similar in the intervention and control groups.Conclusions and ImplicationsOur rigorous RCT on end-of-life care training intervention demonstrated no effects on residents’ HRQoL or their use of hospitals. Unsupported training interventions alone might be insufficient to produce meaningful care quality improvements.     

Modification of the multiplex plasmid PCR assay for Borrelia miyamotoi strain LB-2001 based on the complete genome sequence reflecting genomic rearrangements differing from strain CT13–2396

The genome of Borrelia spp. consists of an approximate 1 megabase chromosome and multiple linear and circular plasmids. We previously described a multiplex PCR assay to detect plasmids in the North American Borrelia miyamotoi strains LB-2001 and CT13–2396. The primer pair sets specific for each plasmid were derived from the genome sequence for B. miyamotoi strain CT13–2396, because the LB-2001 complete sequence had not been generated. The recent completion of the LB-2001 genome sequence revealed a distinct number of plasmids (n = 12) that differed from CT13–2396 (n = 14). Notable was a 97-kilobase plasmid in LB-2001, not present in CT13–2396, that appeared to be a rearrangement of the circular plasmids of strain CT13–2396. Strain LB-2001 contained two plasmids, cp30–2 and cp24, that were not annotated for strain CT13–2396. Therefore, we re-evaluated the original CT13–2396-derived multiplex PCR primer pairs and determined their location in the LB-2001 plasmids. We modified the original multiplex plasmid PCR assay for strain LB-2001 to include cp30–2 and cp24. We also determined which LB-2001 plasmids corresponded to the amplicons generated from the original CT13–2396 primer sets. These observations provide a more precise plasmid profile based on the multiplex PCR assay and reflect the complexity of gene rearrangements that occur in B. miyamotoi strains isolated from the same geographic region.     

Use of mammalian museum specimens to test hypotheses about the geographic expansion of Lyme disease in the southeastern United States

Lyme disease, caused primarily in North America by the bacterium Borrelia burgdorferi sensu stricto, is the most frequently reported vector-borne disease in North America and its geographic extent is increasing in all directions from foci in the northeastern and north central United States. Several southeastern states, including Virginia and North Carolina, have experienced large increases in Lyme disease incidence in the past two decades, with the biggest changes in incidence occurring in the western portion of each state. We tested the hypothesis that B. burgdorferi s.s. was present in western Virginia and North Carolina Peromyscus leucopus populations prior to the recent emergence of Lyme disease. Specifically, we examined archived P. leucopus museum specimens, sampled between 1900 and 2000, for B. burgdorferi s.s. DNA. After confirming viability of DNA extracted from ear punch biopsies from P. leucopus study skins collected between 1945 and 2000 in 19 Virginia counties and 17 North Carolina counties, we used qPCR of two species-specific loci to test for the presence of B. burgdorferi s.s. DNA. Ten mice, all collected from the Eastern Shore of Virginia in 1989, tested positive for presence of B. burgdorferi; all of the remaining 344 specimens were B. burgdorferi-negative. Our results suggest that B. burgdorferi s.s was not common in western Virginia or North Carolina prior to the emergence of Lyme disease cases in the past two decades. Rather, the emergence of Lyme disease in this region has likely been driven by the relatively recent expansion of B. burgdorferi s.s. in southward-moving ticks and reservoir hosts in the mountainous counties of these two states.     

Comprehensive screening of tick-borne microorganisms indicates that a great variety of pathogens are circulating between hard ticks (Ixodoidea: Ixodidae) and domestic ruminants in natural foci of Anatolia

Grazing domestic ruminants serve as important reservoirs and/or amplificatory hosts in the ecology of tick-borne pathogens (TBPs) and tick vectors in the natural foci; however, many enzootic life cycles including ruminants and ticks are still unknown. This study investigated a wide range of TBPs circulating among ticks and grazing ruminants in the natural foci of Anatolia, Turkey. Tick specimens (n = 1815) were collected from cattle, sheep, and goats in three ecologically distinct areas (wooded, transitional, and semi-arid zones) of Anatolia and identified by species: Dermacentor marginatus, Dermacentor reticulatus, Hyalomma anatolicum, Hyalomma excavatum, Hyalomma marginatum, Hyalomma scupense, Haemaphysalis inermis, Haemaphysalis parva, Haemaphysalis punctata, Haemaphysalis sulcata, Ixodes ricinus, Rhipicephalus bursa, and Rhipicephalus turanicus. PCR-sequencing analyses revealed TBPs of great diversity, with 32 different agents identified in the ticks: six Babesia spp. (Babesia occultans, Babesia crassa, Babesia microti, Babesia rossi, Babesia sp. tavsan1, and Babesia sp. Ucbas); four Theileria spp., including one putative novel species (Theileria annulata, Theileria orientalis, Theileria ovis, and Theileria sp.); one Hepatozoon sp.; four Anaplasma spp., including one novel genotype (Anaplasma phagocytophilum, Anaplasma marginale, Anaplasma ovis, and Anaplasma sp.); six unnamed Ehrlichia spp. genotypes; Neoehrlichia mikurensis; nine spotted fever group rickettsiae, including one putative novel species (Rickettsia aeschlimannii, Rickettsia slovaca, Rickettsia hoogstraalii, Rickettsia monacensis with strain IRS3, Rickettsia mongolitimonae, Rickettsia raoultii, Candidatus Rickettsia goldwasserii, Candidatus Rickettsia barbariae, and Rickettsia sp.); and Borrelia valaisiana. Detailed phylogenetic analyses showed that some of the detected pathogens represent more than one haplotype, potentially relating to the tick species or the host. Additionally, the presence of Neoehrlichia mikurensis, an emerging pathogen for humans, was reported for the first time in Turkey, expanding its geographical distribution. Consequently, this study describes some previously unknown tick-borne protozoan and bacterial species/genotypes and provides informative epidemiological data on TBPs, which are related to animal and human health, serving the one health concept.

Clinical Impact of Subclinical Interstitial Fibrosis or Tubular Atrophy in 1-Hour Allograft Biopsy for Remnant Renal Function in Living Kidney Donors: A Prospective Observational Study

BackgroundPreservation of remnant renal function (RRF) is one of the major concerns among living kidney donors (LKDs). A comprehensive assessment is needed to predict the RRF. In this prospective study, we investigated the roles of histologic findings from a 1-hour allograft biopsy in predicting the RRF.MethodsOur prospective study included 116 LKDs who underwent donor nephrectomy (DN) at our institute. Clinical and radiographic data were obtained from their medical charts. Renal volume parameters were calculated using the preoperative computed tomographic images in the volume analyzer SYNAPSE VINCENT image analysis system. Tissues obtained from allograft biopsy were examined. RRF was defined as the estimated glomerular filtration rate (eGFR) 12 months after DN.ResultsOf 116 LKDs, 95 were finally evaluated. The median age of the LKDs at DN and the preoperative eGFR were 57 years and 80.0 mL/min/1.73 m², respectively. In the histologic analysis, 68 allografts (71.6%) had nonspecific findings involving the glomerulus, vessel, and tubulointerstitium. Interstitial fibrosis or tubular atrophy (IF/TA) was the only significant predictive factor for RRF (P = .039). No significant association was found between renal volume parameters and IF/TA, whereas remnant renal volume adjusted by body weight (RRV/BW) tended to be relatively correlated with IF/TA (P = .072). Furthermore, LKDs with subclinical IF/TA tended to have decreased RRV/BW compared with those without subclinical IF/TA (P = .088).ConclusionsOur findings suggested that the presence of IF/TA could be a predictive factor for RRF after DN. Further research establishing the predictive model for RRF is warranted to improve the outcomes of LKDs.
