PURPOSE: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. METHODS: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. RESULTS: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6+/-2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18+/-2.10 vs 4.79+/-1.49 days, P=.17) and total fever duration (5.32+/-2.07 vs 6.41+/-3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. CONCLUSION: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective.

Purpose: This study aimed to investigate the risk factors for cardiac implantable electronic device (CIED)-related infections within the first post-procedural year after CIED insertion. Methods: This study included 509 adult patients undergoing CIED implantation procedures between January 1, 2011 and December 31, 2015. The data were analyzed by t-test, chi-square test, Fisher’s exact test, and logistic regression analysis using SPSS/WIN 23.0. Results: Fifteen infections and 494 non-infections were examined. The CIED-related infection rate was 2.9%; patients with 14 pocket infections and one bacteremia were included in the CIED-related infection. The risk factors of CIED-related infections were the estimated glomerular filtration rate (eGFR) of ≤ 45 mL/min/1.73 m2 (Odds ratio [OR] = 4.03, 95% confidence interval [CI],1.15-14.10) and taking a new oral anticoagulant (NOAC) (OR = 4.50, 95% CI 1.09-18.55). Conclusion These results identified the CIED infection rate and risk factors of CIED-related infection. It is necessary to consider these risk factors before the CIED implantation procedure and to establish the relevant nursing interventions.

OBJECTIVE: The purpose of this study was to determine the frequency and distribution of cytogenetically abnormal miscarriages in couples with spontaneous abortions (SA) or recurrent miscarriages (RM). METHODS: Karyotyping of specimens from 164 abortuses with SA and 86 abortuses with RM was successfully performed according to the standard cytogenetic methods using G-banding technique. RESULTS: Among the total 164 cases of SA group, 81 (49.4%) were euploid and the rest (83, 50.6%) showed chromosomal abnormalities. In RM(> or =2) and RM(> or =3) group, 31 (36.0%)/27 (34.6%) cases were euploid and 55 (64.0%)/51(65.4%) cases were abnormal, respectively. A statistically significant difference was found in the rate of cytogenetic abnormality between SA and RM groups (P<0.05). In all groups, women with advanced maternal age (> or =35 years) had a higher rate of chromosome anomalies compared with women younger than age 35 (normal:abnormal = 32.4%:67.6% for > or =35 years and 53.8%:46.2% for <35 years in SA; 19.2%:80.8%/21.7%:78.3% for > or =35 years and 43.3%:56.7%/40.0%:60.0% for <35 years in RM(> or =2) and RM(> or =3), respectively; P<0.05). In SA group, an increase of normal karyotypes was noted with increased gestational age (<10 week, 38.0%; 10-15 week, 53.5%; 16-20 week, 65.7%). In RM group, most of cases were in <10 week and the frequency of trisomies with chromosomes 1 to 10 were increased compared with that of SA. CONCLUSION: There was a statistically significant difference in the frequency and distribution of chromosomal abnormalities between SA and RM groups. Our results will provide useful information for diagnosis and genetic counseling of patients with SA or RM.

Hepatitis C virus (HCV) is a major cause of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. HCV core protein has been shown to modulate various cellular signaling pathways including the nuclear factor κB (NF-κB) pathway which is associated with inflammation, cell proliferation and apoptosis. However, there have been conflicting reports about the effect of HCV core protein on NF-κB pathway, and the mechanism by which the core protein affects NF-κB activity remains nuclear. In this study, the functional interaction of HCV core protein and IκB kinase γ (IKKγ) was investigated using the expression plasmids of core and the components of IKK complex. The data revealed that HCV core protein activates NF-κB. Also, HCV core protein up-regulated the phosphorylation and degradation of IκBα. The activating effect of HCV core protein on NF-κB was synergistically elevated by IKKγ. It was noticed that the N-terminal IKKβ binding site, C-terminal leucine zipper, and zinc finger domains of IKKγ are not necessary for its synergistic effect. HCV core protein and IKKγ appeared to activate NF-κB by up-regulating the IKKβ activity resulting in the degradation of IκBα. As expected, HCV core protein induced the expression of NF-κB-targeted pro-inflammatory genes such as iNOS, IL-1β and IL-6 in the transcription level. These results suggest that HCV core protein induces NF-κB through the interaction with IKKγ and may play a critical role in the development of inflammation and related liver diseases.

CMV is a largest member of herpes viridae consisted of 230-240 Kb double stranded DNA, 20 protein matrix and envelope. It has specific replication cycle with 3 phase. Human immunity against CMV, cellular immune and humoral immune are envolved and specially CD + 8 cytotoxic cell and natural killer cell are important because they controll primary infection, recurrent infection and latent infection. Our patient was 2 month old, healthy female infant. She had acute pneumonia and then progressed fulminent respiratory failure, cardiomegaly, hydrocephalus and DIC. At first, we tried to find cause of this condition but couldn't anything. We performed several CMV serologic study and on hospital day 30th, Anti-CMV IgM was positive and increased IgG. And we report the case of CMV pneumonia in a healthy infant.

Objectives: This study aimed to identifying the relationship between exposure to secondhand smoking and oral diseases in adolescents, based on the web-based youth health risk behavior survey from 2020. Methods: Among the 54,948 adolescent respondents to the 16th youth health risk behavior survey in 2020, this study included a total of 48,867 non-smoking adolescent participants who had never used regular cigarettes, vapes, or e-cigarettes. Analysis of the complex sample survey data was performed by applying weights according to the complex sample provided by the Korea Disease Control and Prevention Agency. Cross-tabulation analysis by complex sampling using the RaoScott chi-square test and complex-sample t-test was then performed to identify the relationship between subject characteristics and gingival pain and bleeding prevalence. Finally, a binary logistic regression analysis was performed to determine the effects of secondhand smoking on symptoms of gingival pain and bleeding in non-smoking adolescents. Data were analyzed using SPSS 26.0 version, and the statistical significance level was defined as P<0.05. Results: Among the participants, periodontal disease symptoms were reported 1.201 times (95% confidence interval [CI]: 1.101-1.310) more often in those with exposure to secondhand smoking exposure at home and 1.281 times (95% CI: 1.173-1.398) more often in those with exposure to secondhand smoking in public places than in those who did not report exposure to secondhand smoking. Conclusions The study results suggest that exposure to secondhand smoking increases the risk of gingival pain and bleeding in non-smoking South Korean adolescents and is a risk factor for periodontal diseases.

Objective: The number of patients suffering from dysphagia is increasing in line with societal aging. However, preparing dysphagia diets at home or in welfare facilities is challenging due to the lack of commercially specifically designed products. The thickening agents used to prepare dysphagia meals can be difficult due to changes in viscosity and homogenization. Therefore, this study was performed to prepare dysphagia meals using commercially available foods following the classification system outlined by the International Dysphagia Diet Standardization Initiative (IDDSI). Methods: Commercial foods were categorized as main dishes, side dishes, and snacks. Selected foods were ground or minced, and 1-3 g of thickening agent was added. Following the IDDSI framework, fork flowability, spoon tilt, and gravity flow tests were conducted using a syringe, and based on these evaluations, texture-modified foods were classified as general, minced, ground, or liquid foods. Results: Commercial foods used in the experiment could be used in IDDSI Level 2-7 dysphagia diets after adjusting their structures. Food size and viscosities were appropriately controlled, and an usage manual was developed. Conclusion This study successfully demonstrated the easy incorporation of commercial food products into the dysphagia diets for personal care and welfare facilities. By adopting the described approach, dysphagia patients could be provided various meal options with improved service. In addition, this study suggests possibilities for developing and producing diverse products designed specifically for dysphagia patients.
