This study aimed to analyze the experiences of new nurses during their first year of hospital employment to gather data for the development of an evidence-based new nurse residency program focused on adaptability. Methods: This study was conducted at a tertiary hospital in Korea between March and August 2021 with 80 new nurses who wrote in critical reflective journals during their first year of work. NetMiner 4.5.0 was used to conduct a text network analysis of the critical reflective journals to uncover core keywords and topics across three periods. Results: In the journals, over time, degree centrality emerged as “study” and “patient understanding” for 1 to 3 months, “insufficient” and “stress” for 4 to 6 months, and “handover” and “preparation” for 7 to 12 months. Major sub-themes at 1 to 3 months were: “rounds,” “intravenous-cannulation,” “medical device,” and “patient understanding”; at 4 to 6 months they were “admission,” “discharge,” “oxygen therapy,” and “disease”; and at 7 to 12 months they were “burden,” “independence,” and “solution.” Conclusion:These results provide valuable insights into the challenges and experiences encountered by new nurses during different stages of their field adaptation process. This information may highlight the best nurse leadership methods for improving institutional education and supporting new nurses’ transitions to the hospital work environment.

BACKGROUND AND PURPOSE: Visual assessment of medial temporal-lobe atrophy (MTA) has been quick, reliable, and easy to apply in routine clinical practice. However, one of the limitations in visual assessments of MTA is the lack of widely accepted age-adjusted norms and cutoff scores for MTA for a diagnosis of Alzheimer's disease (AD). This study aimed to determine the optimal cutoff score on a T1-weighted axial MTA Visual Rating Scale (VRS) for differentiating patients with AD from cognitively normal elderly people. METHODS: The 3,430 recruited subjects comprising 1,427 with no cognitive impairment (NC) and 2003 AD patients were divided into age ranges of 50–59, 60–69, 70–79, and 80–89 years. Of these, 446 participants (218 in the NC group and 228 in the AD group) were chosen by random sampling for inclusion in this study. Each decade age group included 57 individuals, with the exception of 47 subjects being included in the 80- to 89-year NC group. The scores on the T1-weighted axial MTA VRS were graded by two neurologists. The cutoff values were evaluated from the area under the receiver operating characteristic curve. RESULTS: The optimal axial MTA VRS cutoff score from discriminating AD from NC increased with age: it was ≥as ≥1, ≥2, and ≥3 in subjects aged 50–59, 60–69, 70–79, and 80–89 years, respectively (all p < 0.001). CONCLUSIONS: These results show that the optimal cutoff score on the axial MTA VRS for diagnosing of AD differed according to the decade age group. This information could be of practical usefulness in the clinical setting.

The associations between storm events, urban runoff and costal water quality have not been well investigated in Korea. A temporal and spatial analysis during summer, 2015 was conducted to determine associates between urban runoff and fecal indicator bacteria (Escherichia coli, Enterococcus) levels at two popular coastal beaches (Gwanganri beach and Haundae beach) in Busan. In this study, a clear relationship between rainfall and elevated number of indicators was observed. Two beaches met the costal beach water health standards after less than 3.0 mm of rain. Only for storms less than 2.5 mm was no observable rainfall effect. Our results revealed that exceedances were greatest in 5 hours following 41.0~45.5 rainfall, then declined the bacterial concentrations in 8 hours after the storm and they generally returned to levels below water health standards within 10~14 hours. But it took 2.7 days to get the level of water quality of dry days. The time required for water quality recovery depends on the intensity and duration of rainfall. In the event of intense rainfall issuance of beach closure by public authorities is warranted to protect public health.

Asian-lineage H5 highly pathogenic avian influenza (HPAI) viruses have caused continuous outbreaks in poultry and wild birds. Development of rapid and accurate diagnostic methods is needed for preventing further spread of the virus and reducing the time required for eradication of the virus. We developed a low-density microarray for the rapid detection and identification of avian influenza virus subtypes H5, H7, and H9 and their pathotypes in a previous study. In the present study, we evaluated previously developed diagnostic microarray using avian influenza viruses isolated in Mongolia, including H5 HPAI viruses. All H5 HPAI viruses isolated in Mongolia were shown as H5-specific and highly pathogenic pattern in the microarray. H2, H3 and H12 viruses isolated in Mongolia used in this study did not show any H5, H7 and H9 patterns. These results indicated that this diagnostic microarray has enormous potential for the rapid subtyping and pathotyping of influenza viruses, including viruses isolated in Mongolia.

PURPOSE: Sacral cutaneous lesions, such as dimples and hairy patches, may be associated with occult spinal dysraphism and urogenital abnormalities. This study aim to delineate high risk infants who need early screening for intraspinal and urogenital abnormalities by identifying the association between cutaneous lesions and combined abnormalities. METHODS: Sacral ultrasonography was performed in 777 infants with sacral cutaneous lesions from January 2010 to July 2014. Of these, 317 infants underwent abdominal ultrasonography for urogenital abnormalities. We reviewed the patient's medical records and radiographic findings retrospectively. RESULTS: Of the 777 infants, abnormal intraspinal findings such as tethered cord or meningocele were reported in 26 (3.4%). Sixteen of these 26 patients with abnormal findings underwent follow-up ultrasonography or MRI; 4 infants were diagnosed with lipomeningomyelocele through MRI, and 1 infant underwent a neurosurgical procedure. Among the 317 infants who underwent abdominal ultrasonography, 78 infants (24.6%) had congenital hydronephrosis and 8 infants (2.5%) had other urogenital abnormalities including duplication of kidney, vesicoureteral reflux, horseshoe kidney, renal cyst, or multicystic dysplastic kidney. Urogenital abnormalities were more common in patients with sacral dimples associated with hair or deviated gluteal folds than in those with simple dimples (OR 3.24 and 8.88; P=0.007 and P=0.001, respectively). CONCLUSION: Midline sacral cutaneous lesions may be associated with occult spinal dysraphism and urogenital abnormalities. To detect intraspinal lesions, ultrasonography is recommended for infants with sacral cutaneous lesions. Likewise, infants with sacral dimples associated with either hair or deviated gluteal folds, should be evaluated via abdominal ultrasonography to assess for combined urogenital abnormalities.

OBJECTIVES: This study was conducted in order to analyze oral health content and its importance in primary, middle, and high school textbooks. METHODS: A total of 1,176 textbooks was reviewed, and the items under investigation included: textbook division (national/authorized), titles; grade levels, semesters taught, inclusion of educational content for general and oral health, and the number of pages and rows containing the oral health information. The data were analyzed via paired t-tests, frequency analyses, and one-way ANOVAs. RESULTS: Oral health content was found in 12.1 percent of the primary school textbooks, 6.5% of the middle school texts, and 2.1% of the high school textbooks. The total average was 5.4%. Among the textbooks containing health (general and oral) content, the average number of pages (P<0.001) containing general and oral health information were 22.1 and 0.5, respectively. The average number of lines (P<0.001) for both types of health information were 475.1 and 6.2, respectively, in the primary school textbooks. Middle school textbooks included average numbers of health information-related pages (P<0.001) of 45.7 and 0.4 and average numbers of lines (P<0.001) of 1,086.9 and 5.3, respectively. The average number of pages (P<0.001) in the high school books containing general and oral health content were 83.0 and 0.9, respectively, and the average number of lines (P<0.001) were 2,128.6 and 10.7. Our research showed that, regarding the degree of reflecting oral health education objectives, high school textbooks gained 1.00 point (1 objective), middle school books obtained 0.67 point (5 objectives), and primary school books received 0.18 point (39 objectives; P<0.05). CONCLUSIONS: Oral health content in textbooks decreased as school level increased. The objectives of oral health education for primary school were not properly reflected in the textbooks because the objectives were relatively diverse, and the textbook treatment of the material was rather static.

BACKGROUND/AIMS: During endoscopic retrograde cholangiopancreatography (ERCP), all efforts should be made to be aware of radiation hazards and to reduce radiation exposure. The aim of this study was to investigate the status of radiation protective equipment and the awareness of radiation exposure in health care providers performing ERCP in Korean hospitals. METHODS: A survey with a total of 42 questions was sent to each respondent via mail or e-mail between October 2010 and March 2011. The survey targeted nurses and radiation technicians who participated in ERCP in secondary or tertiary referral centers. RESULTS: A total of 78 providers from 38 hospitals responded to the surveys (response rate, 52%). The preparation and actual utilization rates of protective equipment were 55.3% and 61.9% for lead shields, 100% and 98.7% for lead aprons, 47.4% and 37.8% for lead glasses, 97.4% and 94.7% for thyroid shields, and 57.7% and 68.9% for radiation dosimeters, respectively. The common reason for not wearing protective equipment was that the equipment was bothersome, according to 45.7% of the respondents. CONCLUSIONS: More protective equipment, such as lead shields and lead glasses, should be provided to health care providers involved in ERCP. In particular, the actual utilization rate for lead glasses was very low.

BACKGROUND: Bortezomib has significant activity in treating multiple myeloma (MM). The risk of herpes zoster (HZ) has been reported to increase significantly with bortezomib treatment, but the predisposing factors for HZ are not clear. This study is a retrospective analysis of the relevant risk factors for HZ in Korean MM patients treated with bortezomib. METHODS: Sixty-six patients with refractory or relapsed MM who underwent chemotherapy with bortezomib were included in the study. Prophylactic antiviral drugs were not used for treatment. The following parameters were reviewed: age, gender, stage and type of MM, extent of previous treatment, history of HZ, duration from the time of diagnosis to the time of bortezomib treatment initiation, and absolute lymphocyte counts (ALC) at the time of bortezomib treatment initiation. RESULTS: The incidence of HZ was 16.7%. There were no intergroup differences between the HZ-positive and the HZ-negative groups with regard to a history of HZ, number of previous treatments, and exposure to steroids before bortezomib treatment. The median duration from the time of MM diagnosis to the time of bortezomib treatment initiation in the HZ-positive group was significantly shorter than that in the HZ-negative group. The median ALC at the time of bortezomib initiation in the HZ-positive group was significantly lower than that in the HZ-negative group. CONCLUSION: Bortezomib itself might act as a risk factor for HZ by inhibiting cell-mediated immunity, and patients with low ALC at the time of bortezomib treatment initiation were at greater risk of HZ during bortezomib treatment.

Myasthenia gravis is an autoimmune disorder affecting the neuromuscular junction. It may considerably affect the course of the pregnancy and cause serious compications in both the mother and the infant. Antibodies to nicotinic acetylcholine receptors are the cause of the disturbant nerve impulse transmission to muscle fibers. The clinical state at the beginning of pregnancy does not predict the occurrence of exacerbations or remissions. Each pregnancy has its effect on myasthenia gravis symptoms and does not predict the course of subsequent pregnancies. We experienced a patient received respiratory support because of poor ventilation after repeat caesarean section, but she recovered without complications soon. Two days later after operation, she complained of dysphasia, dysarthria. Then, Tensilon test and acetylcholine receptor antibody test were done. She was diagnosed as myasthenia gravis and administered pyridostigmine as therapeutic dose. We present this case with brief review of the concerned literatures.
