Purpose: The aim of the study was to verify the validity and reliability of the Korean version of the General Attitudes towards Artificial Intelligence Scale (GAAIS-K) for nursing students. Methods: Data from 235 participants were collected from April 12 to April 26, 2022. A total of 230 participants’ data were analyzed. The data were analyzed for content, discriminant, known-groups, and construct validity using content validity index, correlation coefficient, and confirmatory factor analyses. The reliability of the GAAIS-K was examined using internal consistency and test-retest analyses. Results: The expert-rated content validity index was ≥.80. The sub-scales of the GAAIS-K were moderately correlated with attitude toward accepting technology, indicative of its discriminant validity. The male students’ positive attitude score was significantly higher than that of the female students, satisfying the known-groups validity. Cronbach’s α for the scale was .86 (positive) and .74 (negative), and the intra-class correlation coefficient for the two-week test-retest reliability was .86 (positive) and .60 (negative). The scores for positive and negative attitudes were 3.68±0.46 and 3.05±0.55. Conclusion This study shows that the GAAIS-K is a valid and reliable instrument for assessing nursing students. Additional research is recommended to continue the evaluation of the GAAIS-K with a focus on healthcare settings.

A 7-month-old boy was presented with growth retardation. The brain CT scan and the cerebral angiography revealed hydrocephalus resulting from venous hypertension and a high-flow direct arteriovenous fistula at the distal M2 segmnt of the middle cerebral artery which was drained into the sphenoparietal sinus. The echocardiogram disclosed a ventricular hypertrophy. The patient was treated by gradual ligation of fistulous portion in ten minutes to prevent sudden increase of peripheral resistance and cardiac overloading. It is stressed that slow obliteration of an arteriovenous fistula is a paramount procedure to prevent congestive heart failure.

Reports of bowing and pseudarthrosis of the humerus and clavicle are rare. Most patients with congenital pseudoarthrosis of the clavicle involving the right side and midportion of clavicle tended to heal better than congenital pseudoarthrosis of the tibia. We experienced a patient who had special features in terms of location, pseudoarthrosis pattern, and neurofibromatosis, and report on this case here.

OBJECTIVE: Albumin creatinine ratio (ACR) in a spot urine is replacing albumin excretion rate (AER) in 24 hour-collected urine as screening test for microalbuminuria because of simplicity and reliance. There are some controversies about the most relevant ACR value in detecting microalbuminuria. Most commonly recommended cut-off value is 30 mg/gm. Some recommends sex-specific ACR cut-off value: 17 mg/gm for men, 25 mg/gm for women. In this report, we evaluated diagnostic characteristics of ACR according to above different cut-off values and estimated most relevant ACR cut-off value for microalbuminuria in patients with type 2 diabetes. METHODS: Urine was collected for 24hours for the measurement of microalbumin in type 2 diabetes who admitted in SNUH. The next day, first morning urine was obtained for microalbumin and creatinine concentration in patients with albumin excretion rate (AER) below 300 mg/day. RESULTS: 33% of total 156 patients had microalbuminuria. ACR correlated positively with AER. According to regression equations of AER and ACR, an AER of 30 mg/day corresponded to an ACR of 32 mg/gm. Positive and negative predictive values of ACR 30 mg/gm for microalbuminuria were 81% and 84% in men. In women, these were 80% and 86% respectively. Using recommended sex-specific ACR cutoff values, these were 52% and 94% in men, 68% and 91% in women. The most relevant ACR cutoff from receiver operating characteristics curve was 32 mg/gm in our study. CONCLUSION: Using ACR 30 mg/gm as cut-off values of microalbuminuria, positive and negative predictive value were above 80% in both men and women. In patients visiting SNUH, ACR 32 mg/gm may be more relevant in screening microalbuminuria in type 2 diabetes.

Diffuse proliferative lupus nephritis(DPLN) is the most severe form in lupus nephritis. We retrospectively analyzed 90 DPLN patients who were confirmed by kidney biopsy and treated at least for 12 months to compare the effectiveness of treatment modalities and to investigate the prognostic factors of DPLN. The patients were categorized as intravenous cyclophosphamide pulse(CY) group and oral corticosteroid(with or without cytotoxic drug; PO) group. When CY group(69pts) and PO group(21pts) were compared, there was no differences between two groups in sex, age, follow-up months, chronicity index(CI, 4.55 vs 3.76; CY vs PO, respectively), complications of treatment, mortality rate(4.3% vs 0%), remission rate of nephritis(at 3 year; 59.1% vs 75.5%) and renal survival rate(at 5 years; 88.0% vs 91.7%), b ut significant differences in frequency of nephrotic syndrome(66.7% vs 33.3%) and azotemia (30.4% vs 0%), activity index(7.14 vs 4.33) and relapse rate(2.9% vs 42.9%). When remission group (49pts) and nonremission group(41pts) were compared, the CI, initial azotemia, tubular atrophy, glomerular sclerosis, sex and duration of nephritis were prognostic factors for remission in univariate analysis, and CI(OR, 9.89) and sex(OR, 10.99) in multivariate analysis. When remission group(35pts) and nonremission(34pts) group were compared in CY group, the CI, initial azotemia and tubular atrophy were the prognostic factors in univariate analysis, and CI(OR, 7.69) in multivariate analysis. The initial azotemia was the only prognostic factor for renal survival. We concluded that the CI, sex and initial azotemia were the prognostic factors for renal remission and survival, but the treatment modality was not in DPLN. Therefore it is necessary to evaluate the prognostic factors before decision of treatment modality.

Hepatitis B virus(HBV) infection has been suggested as the etiologic agent in membranoproliferative glomerulonephritis(MPGN), but the mechanism by which HBV infection leads to MPGN in human has not been established. To localize the HBV antigen and HBV-DNA in the kidney tissue, we examined paraffin sections of kidney biopsies which were positive for HBsAg by immunohistochemical study from 13 HBV carriers with MPGN (HBV-MPGN). Polymerase chain reaction(PCR) and in situ PCR(ISP) were used for the HBV DNA amplification and localization in kidney tissues. Primers used in PCR and ISP were from the S, C, and X HBV-DNA regions. Immunohistochemical study showed HBsAg deposits on the mesangium and glomerular capillaries. Arteriolar deposits were also occasionally observed. PCR for the S, C, and X regions were positive in 11 patients(85%), 11 patients(85%), and 9 patients (69%), respectively. The PCR findings were further confirmed by direct sequencing of PCR products and the amplification of HSP70 gene as a control. ISP showed the amplified HBV-DNA at the glomeruli and renal tubules. For S region, ISP was positive in 7 patients. For C and X regions, ISP was positive in 8 patients, respectively. 5 patients showed the positive signals for both the glomeruli and tubules, while 4 patients were positive at the tubules only. These 4 patients seemed to have the longer disease durations when compared to the other 5 patients (52.8 months vs. 11.8 months), but it was not statistically significant. In conclusion, the detection and the localization of HBV antigen and DNA in renal tissues indicate the presence of the complete virion in the kidney. These results suggest that HBV may infect the kidneys of HBV carriers with MPGN.
