ABSTRACT
Purpose@#The aim of this study was to identify factors related to the vaccination intentions of nursing students before clinical practice. @*Methods@#A descriptive correlational study design was used. The participants were 129 nursing students who were enrolled in one college of nursing in Seoul and were scheduled for clinical training. Data collection was conducted from February 28 to March 7, 2022. The data were analyzed using descriptive statistics, a t-test, ANOVA, Pearson’s correlation coefficient, and a latitudinal regression analysis using the IBM SPSS statistics version 26.0 program. @*Results@#The intention to vaccinate showed a significant correlation with vaccination attitude (r=.72, p<.001), subjective norms (r=.68, p<.001), and perceived behavioral control (r=.63, p<.001). The influencing factors on three intent to vaccinate were vaccination attitude (β=.36 p<.001), subjective norms (β=.31, p<.001), and perceived behavioral control (β=.36, p<.001). The explanatory power of these variables was 69.6%. @*Conclusion@#The vaccination rate before the clinical training of nursing students was related to economic burden, a lack of time, and transportation problems that nursing college students experienced during the vaccination process. Therefore, administrative and financial support is needed for improving the vaccination rates of nursing students.
ABSTRACT
Background@#Atopic dermatitis (AD) has been clarified that imbalance of bacterial and fungal communities in the skin and gut play key roles in immunologic dysfunction. Atopic keratoconjunctivitis (AKC), one of severe ophthalmic manifestation of AD, could be related with dysbiosis as same as AD. @*Objective@#In this case-control study, the roles of conjunctival microbial communities in AKC were evaluated by a comparative analysis with healthy controls (HCs). @*Methods@#16S rRNA sequencing was used to construct libraries of compositional information for a total of 30 volunteers including 20 patients with AKC and 10 HCs. @*Results@#In the results, variation in the conjunctival taxonomic composition was higher in patients with AKC than in the HC group. In an analysis of relative abundance at the genus level, some taxa significantly differed between groups, including Ralstonia, Staphylococcus, Pseudomonas, Proteus, Haemophilus, and Bifidobacterium(p＜0.05). Beta diversity was significantly higher in patients with AKC than in HCs (PERMANOVA, p=0.004). @*Conclusion@#The results indicated that the diversity and composition of the microbiome differs between patients with AKC and HCs.
ABSTRACT
Purpose@#To evaluate the effects of each subgroup of prostaglandin analogues (PGAs) on central corneal thickness (CCT) in patients with normal tension glaucoma (NTG). @*Methods@#We retrospectively reviewed 55 eyes of 55 patients with NTG who were receiving PGA therapy. Patients who were treated with 0.005% latanoprost (16 eyes), 0.0015% tafluprost (16 eyes), or 0.004% travoprost (23 eyes) monotherapy were included. CCT assessments were performed at baseline and 1, 2, and 3 years after initiation of treatment. @*Results@#In the NTG group, the mean CCT showed a decreasing trend, and there was a significant difference in mean CCT at 1, 2, and 3 years compared with baseline (baseline, 538.16 ± 32.14; 1 year, 526.55 ± 37.30 µm [p = 0.00]; 2 years, 521.67 ± 36.79 µm [p = 0.00]; 3 years, 520.43 ± 36.88 µm [p = 0.00]). The reduction of CCT was confirmed by subgroup analysis. In the 0.005% latanoprost group, mean CCT was decreased at 1 year (p = 0.11), 2 years (p = 0.00), and 3 years (p = 0.02). In the 0.0015% ta-fluprost group and the 0.004% travoprost group, mean CCT was also significantly decreased at all years (p = 0.00). No statisti-cal difference was observed between the NTG subgroups (p = 0.06). @*Conclusions@#Topical therapy with PGAs appeared to cause a significant decrease in CCT reduction in patients with NTG. A long-term follow-up study including more participants is needed.
ABSTRACT
Purpose@#We quantitatively analyzed the therapeutic effects of intravitreal anti-vascular endothelial growth factor (anti-VEGF) and dexamethasone implants used to treat macular edema caused by retinal vein occlusion. @*Methods@#Eighty-three patients with branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO) with macular edema treated from February 2009 to August 2019 via anti-VEGF injections or dexamethasone implants were enrolled. The medical records of 83 eyes were retrospectively analyzed. Horizontal B-scan spectral domain optical coherence tomography images spanning the foveal center were obtained before treatment and 1 month later. These were analyzed with the aid of Image J software and the numbers of pixels corresponding to intraretinal and subretinal fluids calculated. @*Results@#In patients with BRVO, the retinal fluid changes were identical 1 month after injection in both the anti-VEGF injection and the dexamethasone implant groups. For CRVO cases, the dexamethasone implant group exhibited a significantly higher loss of retinal fluid and thus a greater reduction in retinal edema than the anti-VEGF group. Linear regression analysis revealed that in BRVO cases poor final visual acuity was associated with a large amount of fluid at baseline and poor visual acuity 1 and 3 months after treatment. In CRVO cases, poor final visual acuity was associated with a large change in the intraretinal fluid level and poor visual acuity 3 months after treatment. @*Conclusions@#The extent of anatomical and visual acuity improvement did not differ between the anti-VEGF injection and the dexamethasone injection groups with BRVO. For CRVO patients, the short-term anatomical improvement was significantly greater in the latter group, but the extent of vision improvement was significantly higher in the former group.

ABSTRACT
Reserpine is a well-known medicine for the treatment of hypertension, however the role of reserpine in cell signaling is not fully understood. Here, we report that reserpine treatment induces the phosphorylation of AMP activated protein kinase (AMPK) at threonine 172 (T172) in PC12 cells. Phosphorylation of AMPK T172 is regulated by upstream signaling molecules, and the increase of phospho-T172 indicates that AMPK is activated. When we examined the FOXO3a dependent transcription by using the FHRE-Luc reporter assay, reserpine treatment repressed the FHRE-Luc reporter activity in a dose dependent manner. Finally, we showed that reserpine treatment induced the phosphorylation of AMPK as well as cell death in MCF-7 cells. These results suggest that AMPK is a potential cellular target of reserpine.
