Purpose: To compare the structural features of the optic nerve head (ONH) in moderate glaucoma patients with single-hemispheric and bi-hemispheric visual field (VF) defects. Methods: Patients with open-angle glaucoma (OAG) and a VF mean deviation between -6 and -12 dB were retrospectively enrolled. Based on VF defect patterns, eyes were classified into two groups: those with single-hemispheric VF defects and those with bi-hemispheric VF defects. Structural features analyzed included Bruch’s membrane opening area, lamina cribrosa (LC) thickness, temporal β-zone parapapillary atrophy with and without Bruch's membrane (βPPA+BM, βPPA-BM, respectively), and peripapillary retinal nerve fiber layer thickness using spectral-domain optical coherence tomography. Results: Out of 137 eyes from 124 patients, 80 eyes had single-hemispheric VF defects and 57 eyes had bi-hemispheric VF defects. The bi-hemispheric group exhibited longer axial length (p = 0.038), thinner central corneal thickness (p = 0.003), thinner LC (p < 0.001), and larger temporal βPPA+BM (p = 0.002) compared to the single-hemispheric group. Conclusions Among Korean OAG patients with moderate VF defects, those with bi-hemispheric VF defects showed more structurally vulnerable optic discs characterized by longer axial lengths, thinner central corneal thickness, thinner LC, and larger β PPA+BM compared to those with single-hemispheric VF defects. These findings underline the importance of evaluating ONH structures in monitoring glaucoma progression particularly in patients with extensive VF damage.

Background: Hand hygiene is considered the simplest and most cost-effective method of infection prevention. Regular observation and feedback on hand hygiene compliance are key strategies for its enhancement. This study evaluated the effectiveness of hand hygiene surveillance, including direct observation and feedback, by comprehensively analyzing the reported hand hygiene compliance within the Korean National Healthcare-Associated Infections Surveillance System from 2019 to 2022. Methods: Participating medical institutions included general hospitals and hospitals with infection control departments that consented to participate. Hand hygiene surveillance was conducted using direct observation. Collected data, including healthcare workers, clinical areas, hand hygiene moments, and hand hygiene compliance, were recorded to calculate hand hygiene compliance rates. Additionally, the volume of alcohol-based hand sanitizers used per patient per day was investigated as an indirect indicator of hand hygiene compliance. The study was conducted from July 2019 to December 2022. Results: Hand hygiene compliance increased from 87.2% in Q3 2019 to 89.9% in 2022. Nurses and medical technologists showed the highest compliance rates, whereas doctors showed the lowest compliance rates. Intensive care units excelled in compliance, whereas emergency de partments lagged. Compliance was highest after patient contact and lowest when the patient’s surroundings were touched. Larger hospitals consumed more alcohol-based hand sanitizers than smaller hospitals did. Conclusion This study confirmed an improvement in hand hygiene compliance through sustained surveillance, indicating its contribution not only to preventing infection transfer within healthcare facilities but also to fostering a culture of hand hygiene in the country.

Salmonella enterica serotype Choleraesuis causes swine paratyphoid, with clinical findings of enterocolitis and septicemia. However, the clinicopathological features of S. Choleraesuis infections in pigs have not been reported in Korea. We describe the pathological findings of two weaned pigs with S. Choleraesuis infections, presenting with diarrhea, cough, and sudden death. Pathological examination indicated severe necrotic colitis in pig 1 and septicemic lesions in pig 2. Multidrug-resistant S. Choleraesuis was isolated from the pigs’ lungs and intestinal contents. Further research is required for the surveillance of S. Choleraesuis infections in pigs and the virulence estimation in the S. Choleraesuis isolates.

PURPOSE: The purpose of this study was to investigate the welfare status of nurses and the status of fixed night shifts and flexible work arrangements in both general hospitals and advanced general hospitals in Korea. METHODS: A total of 167 hospitals participated in this study, done from April to October 2018. RESULTS: There were 103 hospitals utilizing the fixed night shift system, 22 in the two-shift system, 3 in the fixed holiday shift, 79 in the fixed shift system, and 39 in the short-time working system. The average welfare benefits for nurses increased to 33.02 million won on average. However, welfare services for the nurses were poor: 41.8% of the respondents had a nurses' lounge, 81.7% were given dormitory space at their place of employment, 41.8% had access to welfare facilities, and 56.4% were provided with welfare support countermeasures. CONCLUSION: The results show an increasing trend of hospitals to utilize fixed night shift and flexible work arrangements. An institutional strategy at the national policy level should be established to implement flexible work arrangements including the fixed night shift system, which has a poor level of welfare.

BACKGROUND: Previous randomized controlled trials of revascularization for atherosclerotic renal artery stenosis (ARAS) were not successful. We investigated the effects of percutaneous transluminal angioplasty with stent insertion (PTA/S) on kidney function and blood pressure (BP) control in patients with ARAS. METHODS: From 2000 to 2017, 47 subjects who underwent PTA/S for ARAS were identified. A high-risk group was defined, composed of patients having one or more of the following clinical presentations: pulmonary edema, refractory hypertension, and rapid deterioration of kidney function. Subjects who met the criteria of ‘kidney function improvement’ or ‘hypertension improvement’ after PTA/S were classified as responders. RESULTS: Twenty-one (44.7%) subjects were classified into the high-risk group. Two subjects (8.0%) in the low-risk group (n = 25) and 5 subjects (27.8%) in the high-risk group (n = 18) showed improvement in kidney function after PTA/S (P = 0.110). In patients with rapid decline of kidney function, estimated glomerular filtration rate improved from 28 (interquartile range [IQR], 10–45) mL/min/1.73 m² to 41 (IQR, 16–67) mL/min/1.73 m² at 4 months after PTA/S, although the difference was not significant (P = 0.084). Regarding BP control, 9 (36.0%) and 14 (77.8%) subjects showed improvement after PTA/S in the low- (n = 25) and high-risk (n = 18) groups, respectively (P = 0.007). In patients with refractory hypertension, the systolic BP dropped from 157 (IQR, 150–164) mmHg to 140 (IQR, 131–148) mmHg at 4 months after PTA/S (P = 0.005). Twenty-five subjects were defined as responders and comprised a significant proportion of the high-risk group (P = 0.004). CONCLUSION: PTA/S might improve BP control and kidney function in patients with ARAS presenting with high-risk clinical features. The optimal application of PTA/S should be based on individual assessment of the clinical significance of renal artery stenosis.

PURPOSE: To characterize the development of glaucoma, age of glaucoma onset, and treatments for patients with a facial port-wine stain (PWS). METHODS: We performed a retrospective analysis of the medical records of 58 patients (116 eyes) with facial PWS between January 2000 and August 2016. We noted patients' age at the initial examination, cup-to-disc ratio, corneal diameter, occurrence of ocular hypertension, development of glaucoma, age of glaucoma onset, and treatments. We compared the clinical features of eyes that developed glaucoma with those that did not develop glaucoma. Among those eyes with glaucoma, we investigated the differences between eyes that underwent surgery and those that did not undergo surgery. RESULTS: Among the 58 patients with a facial PWS (116 eyes), glaucoma was diagnosed in 38 patients (46 eyes; 39.66%). Of these, 26 patients (27 eyes; 58.69%) underwent glaucoma surgery. PWS-associated glaucoma usually developed by the age of 2 years (85.61%). In all patients, glaucoma developed on the same side of the face as the PWS. Of the 58 patients, 19 (32.76%) showed neurological symptoms, including seizures, developmental delays, intellectual disabilities, or hemiplegia, and 32 (55.17%) were diagnosed with Sturge-Weber syndrome. The mean number of glaucoma surgeries was 1.55 ± 0.93. The initial surgery included trabeculectomy (7 eyes), trabeculotomy (5 eyes), combined trabeculotomy/trabeculectomy (13 eyes), and aqueous drainage device insertion (2 eyes). The mean age at the first surgery was 35.14 ± 50.91 months. In 18 of 27 eyes (66.67%), the postoperative intraocular pressure (IOP) was controlled to below 21 mmHg, but 9 eyes (33.33%) showed elevated IOP and required a reoperation. CONCLUSIONS: PWS can be accompanied by ocular hypertension or glaucoma, so patients require regular ophthalmic examinations. When glaucoma occurs, it often does not respond to medication, making it difficult in some cases to control the IOP, so appropriate glaucoma surgery is necessary.

There are 82 dental hygiene departments and clinical training institutes across the country with a very wide range of clinical practice content and evaluation methods, making standardization difficult. Therefore, there is a need to establish a standard protocol outlining clinical practice content and evaluation methods for systematic and efficient operation of clinical practice. Thus, this study attempted to propose such a protocol for standardization of dental hygiene clinical practice in dental clinics and hospitals to examine the contents of clinical practice by reviewing relevant literature, and relating it to professional practice within the dental hygienic curriculum to facilitate enhancement of expertise. Clinical practice content was extracted from 74 cases, and was consisted of classifying mandatory and optional clinical practice, training time, and activity methods for each component. To standardize effective clinical practice, it is necessary to organize the components acquired in the course of clinical dentistry training in line with their arrangement on each university's curriculum, in order to learn all components step by step. To do this, it is necessary to present a standardized clinical practice protocol and a organic cooperation between educational institutions and clinical training institutions.

PURPOSE: The purpose of this study was to examine nursing organizational culture and resilience and their effects on quality of nursing service. METHODS: A cross-sectional study was conducted. A convenience sampling method was used to collect data from 199 participants who worked in a tertiary hospital in G city. Demographic and work related variables, quality of nursing service, resilience, and nursing organizational culture were measured using validated self-report questionnaires. RESULTS: All of the participants were women and the majority were staff nurses and single. A statistically significant difference in quality of nursing service was found for age, marital status, educational level, clinical career, position and perceived health status. Age, educational level, clinical career, position, resilience, innovation-oriented culture, relation-oriented culture, and hierarchy-oriented culture were significant predictors of quality of nursing service, explaining 47% of total variance. Among the predictors, resilience was the strongest predictor, followed by innovation-oriented culture, and hierarchy-oriented culture. CONCLUSION: Findings indicate that quality of nursing service can be improved by raising individual nurse's resilience and advancing nursing organizational culture. Considering the identified factors, researchers and administrators need to develop and provide clinical nurses with a variety of programs to improve the quality of their nursing service.
