BackgroundSelf-management after a stroke is a challenge because of multifaceted care needs and complex disabling consequences that cause further hindrance to patient participation. A 13-week stroke patient empowerment intervention (Health Empowerment Intervention for Stroke Self-management [HEISS]) was developed to enhance patients’ ability to participate in self-management.PurposeTo examine the effects of the empowerment intervention on stroke patients’ self-efficacy, self-management behavior, and functional recovery.MethodsThis is a single-blind randomized controlled trial with stroke survivors assigned to either a control group (CG) receiving usual ambulatory rehabilitation care or the HEISS in addition to usual care (intervention group [IG]). Outcome data were collected at baseline (T0), 1 week (T1), 3 months (T2), and 6 months (T3) postintervention. Data were analyzed on the intention-to-treat principle. The generalized estimating equation model was used to assess the differential change of self-efficacy in illness management, self-management behaviors (cognitive symptom management, communication with physician, medication adherence, and self-blood pressure monitoring), and functional recovery (Barthel and Lawton indices) across time points (baseline = T0, 1 week = T1, 3 months = T2, and 6 months = T3 postintervention) between the two groups.ResultsA total of 210 (CG =105, IG =105) Hong Kong Chinese stroke survivors (mean age =69 years, 49% women, 72% ischemic stroke, 89% hemiparesis, and 63% tactile sensory deficit) were enrolled in the study. Those in IG reported better self-efficacy in illness management 3-month (P=0.011) and 6-month (P=0.012) postintervention, along with better self-management behaviors at all follow-up time points (all P<0.05), apart from medication adherence (P>0.05). Those in IG had significantly better functional recovery (Barthel, all P<0.05; Lawton, all P<0.001), compared to CG. The overall dropout rate was 16.7%.ConclusionPatient empowerment intervention (HEISS) may influence self-efficacy in illness management and improve self-management behavior and functional recovery of stroke survivors. Furthermore, the HEISS can be conducted in parallel with existing ambulatory stroke rehabilitation services and provide added value in sustaining stroke self-management and functional improvement in the long term.
Objective Pre-eclampsia involves a maternal inflammatory response that differs from both normal pregnancy and normotensive intrauterine growth restriction (IUGR). Our objective was to examine neutrophil Toll-like receptor (TLR), cryopyrin, nuclear factor-jB (NF-jB) subunit and interleukin-1b (IL-1b), and inflammatory cytokine profiles in women with preeclampsia or normotensive IUGR, as well as in normal pregnancy and non-pregnancy controls.Design and method A case-control study was performed. We examined the messenger RNA (mRNA) and protein expressions of TLR4 and TLR2, mRNA levels of cryopyrin, IL-1b, NF-jB subunits p50 and p65, as well as maternal serum inflammatory cytokine profiles (IL-2, IL-6, tumour necrosis factor-a [TNF-a], interferon-c [IFN-c] and IL-10) in women with and without pre-eclampsia using real-time reverse transcription polymerase chain reactions, flow cytometry and multiplex immunoassays.Setting A single tertiary maternity hospital in Vancouver, Canada.Population Women with early-onset pre-eclampsia (<34 weeks of gestation, n = 25), women with late-onset pre-eclampsia ( ‡34 +0 weeks of gestation, n = 25), women with normotensive IUGR (n = 25), women with normal pregnancy (n = 75) and non-pregnancy (n = 25) controls.Results Women with pre-eclampsia (as a single combined group of early-and late-onset, and particularly in women with earlyonset pre-eclampsia) had increased TLR2 and TLR4 mRNA and protein expressions elevated cryopyrin, NF-jB subunit, and IL-1b mRNA expression, and TNF-a:IL-10 and IL-6:IL-10 ratios compared with other groups.Conclusions These data suggest that TLRs and cryopyrin may modulate the innate immune response of the maternal syndrome of pre-eclampsia, and might also trigger the differential inflammatory response existing between early onset pre-eclampsia and normotensive IUGR.
Wild deer are one of the important natural reservoir hosts of Anaplasma species, which cause granulocytic anaplasmosis in equines, canines, and humans. The objective of the present study was to determine whether and what species of Anaplasma naturally infect Korean water deer (KWD) in the Republic of Korea. A total of 66 spleens from KWD carcasses were collected by the Conservation Genome Resource Bank for Korean Wildlife in Korea between March 2008 and May 2009. Polymerase chain reaction (PCR) was performed using 16S ribosomal (r)RNA, with ankA, groEL, and msp2 gene primers to amplify the genes of Anaplasma and Ehrlichia. Using 16S rRNA-based nested PCR, Anaplasma phagocytophilum and Anaplasma bovis were detected in 42 (63.6%) and 23 (34.8%) of 66 KWD spleens, respectively. The 42 A. phagocytophilum were classified into five genotypes and the 23 A. bovis were classified into two genotypes by sequence analysis. By ankA-, groEL-, and msp2-based nested PCR, A. phagocytophilum was detected in 1 (1.5%), 7 (10.6%), and 3 (4.6%) of 66 samples, respectively. These gene sequences had only one genotype. Five of seven obtained 16S rRNA gene sequences have never been identified. The ankA, groEL, and msp2 obtained gene sequences represented new genotypes. This is the first report of A. phagocytophilum and A. bovis in KWD, suggesting that they may act as reservoirs for anaplasmosis zoonotic pathogens.
Seed sterilization is essential for preventing seed borne fungal diseases. Sterilization tools based on physical technologies have recently received much attention. However, available information is very limited in terms of efficiency, safety, and mode of action. In this study, we have examined antifungal activity of ozone and arc discharge plasma, potential tools for seed sterilization. In our results, ozone and arc discharge plasma have shown differential antifungal effects, depending on the environment associated with fungal spores (freely submerged in water or infected seeds). Ozone inactivates Fusarium fujikuroi (fungus causing rice bakanae disease) spores submerged in water more efficiently than arc discharge plasma. However, fungal spores associated with or infecting rice seeds are more effectively deactivated by arc discharge plasma. ROS generated in water by ozone may function as a powerful fungicidal factor. On the other hand, shockwave generated from arc discharge plasma may have greatly contributed to antifungal effects on fungus associated with rice seeds. In support of this notion, addition of ultrasonic wave in ozone generating water has greatly increased the efficiency of seed disinfection.
To investigate canine kobuvirus (CaKoV) infection, fecal samples (n = 59) were collected from dogs with or without diarrhea (n = 21 and 38, respectively) in the Republic of Korea (ROK) in 2012. CaKoV infection was detected in four diarrheic samples (19.0 %) and five non-diarrheic samples (13.2 %). All CaKoV-positive dogs with diarrhea were found to be infected in mixed infections with canine distemper virus and canine parvovirus or canine adenovirus. There was no significant difference in the prevalence of CaKoV in dogs with and without diarrhea. By phylogenetic analysis based on partial 3D genes and complete genome sequences, the Korean isolates were found to be closely related to each other regardless of whether they were associated with diarrhea, and to the canine kobuviruses identified in the USA and UK. This study supports the conclusion that CaKoVs from different countries are not restricted geographically and belong to a single lineage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
