Purpose: : This scoping review was designed to identify gaps in knowledge and guide future directions for clinical nursing practices and research on oral hygiene care for endotracheally intubated patients in Korean intensive care units. Methods: : We conducted a scoping review using the methodological framework proposed by Arksey and O’Malley. PubMed, CINAHL, RISS, Science On, and DBpia databases were searched. Two reviewers independently selected the studies and extracted data. A total of 445 studies were identified, of which 17 were included in the final analysis. Results: : No research has been conducted from 2021 to the present. A total of 12 instruments were utilized in 13 studies to assess the effectiveness of oral hygiene care. All studies investigating the effectiveness of oral hygiene care have consistently documented that chlorhexidine has the most significant effect. The frequency and time of oral hygiene care were each examined in one study. Conclusion : A research study is necessary to develop a measurement tool for assessing the effectiveness of oral hygiene care suitable for endotracheal intubated patients in intensive care units. Interventional studies should be conducted to determine the effects of chlorhexidine and the appropriate frequency and time of oral hygiene care. Thereafter, revision of domestic evidence-based clinical practice guidelines by integrating these results will be necessary.

BACKGROUND: Grip strength has been found to be closely related to mortality and disease morbidity. In this study, we aimed to evaluate the relationship between grip strength and mortality in middle aged and elderly Koreans.METHODS: Study subjects were selected from the participants of the Korean Longitudinal Study of Ageing from 2006 to 2016. The Cox proportional hazards model was used to analyze the association between grip strength, all-cause mortality, and cause-specific mortality according to age and sex, after adjusting for covariates.RESULTS: The adjusted hazard ratio (HR) for all-cause mortality was decreased in the high grip strength group (male: HR=0.580, 95% confidence interval [CI]=0.478–0.704; female: HR=0.601, 95% CI=0.483–0.747) compared to the low grip strength group in both sexes. In male, cardiovascular mortality (middle group: HR=0.453, 95% CI=0.278–0.738; high group: HR=0.538, 95% CI=0.332–0.871) and cancer mortality (middle group: HR=0.697, 95% CI=0.514–0.945; high group: HR=0.589, 95% CI=0.427–0.812) were significantly lower in the middle and high grip strength groups compared to the low grip strength group. The HR for mortality due to stroke in male decreased significantly according to grip strength, but this became nonsignificant after adjusting for covariates. No association between cause-specific mortality and grip strength was found in female.CONCLUSION: In this study, grip strength was inversely associated with all-cause mortality, with similar effects on cause-specific mortality due to heart disease and cancer in male. Grip strength is a useful predictor of health status, and further studies are needed to evaluate its clinical relevance in Koreans.

Background/Aims: With increased life expectancy, the management of elderly hepatocellular carcinoma (HCC) patients became a crucial issue, yet it is still challenging due to comorbidities and high surgical risks. While surgical resection is considered as primary treatment for eligible HCC patients, systematic evidence on its outcomes in elderly patients remains scarce. In this review, we aimed to analyze the efficacy and safety outcomes of surgical resection in elderly HCC patients. Methods: The studies included in this meta-analysis were selected from Ovid-MEDLINE, OvidEmbase, CENTRAL, KoreaMed, KMbase, and KISS databases following a predefined protocol.Efficacy outcomes included overall survival and disease-free survival, while the safety outcomes included postoperative mortality and complications. Results: Patients in the elderly group (≥65 years) who underwent surgery exhibited non-inferior overall survival (hazard ratio [HR], 1.26; 95% confidence interval [CI], 0.92 to 1.74) and diseasefree survival (HR, 1.03; 95% CI, 0.99 to 1.08) compared to the non-elderly group. Overall postop-erative mortality exhibited no statistical difference (odds ratio [OR], 1.07; 95% CI, 0.87 to 1.31), but 30-day, 90-day, and in-hospital mortality were higher in the elderly group. The incidence of overall complications was higher in the elderly group (OR, 1.44; 95% CI, 1.22 to 1.69). Sensitivity analysis for the super elderly group (≥80 years) showed significantly higher in-hospital mortality compared to the non-super elderly group (OR, 2.51; 95% CI, 1.16 to 5.45). Conclusions The efficacy outcome of surgical resection in the elderly HCC patients was not worse than that in the non-elderly HCC patients, while in-hospital mortality and complications rates were higher. Therefore, surgical resection should be purposefully considered in the elderly population, with careful candidate selection.

BACKGROUND: Self-monitoring of blood glucose is an important component of therapy for diabetes mellitus. The aim of this study was to evaluate the analytic performance evaluation of blood monitoring system G400 according to ISO 15197:2013. METHODS: We evaluated the G400 according to the ISO 15197:2013 guideline, we measured precision, accuracy, interference of hematocrit and interfering substances, user performance. RESULTS: Repeatability and intermediate precision of G400 showed standard deviation 2.7–3.8 mg/dL, 2.4–3.6 mg/dL and coefficient of variation 1.9-2.9% and 1.7–3.7%, respectively. Accuracy measured 98–98.5%, satisfied acceptable criteria. Error grid analysis showed that all results of this study were in zone A. Hematocrit between 20% to 60% did not cause interference. Three of 24 interfering substances were not acceptable criteria, and dose-response evaluation was needed. CONCLUSIONS: This study showed that G400 was considered reliable results satisfying the ISO 15197:2013 criteria

Attention-deficit/hyperactivity disorder (ADHD) is one of the common psychiatric problems in childhood. The symptoms of ADHD tend to last for adulthood and the patients suffer from various comorbid problems and functional impairments. Methylphenidate (MPH) is the first choice of pharmacotherapy for ADHD and many researches have demonstrated its efficacy. We reviewed the clinical trials for efficacy of MPH focusing on Osmotic-Controlled Release Oral delivery System Methylphenidate (OROS MPH). It was identified that MPH improved core symptom of ADHD, peer relationship and health related quality of life and might improve various aspects of cognitive function. It was proved that the efficacy of OROS MPH was better than placebo and comparable to immediate release MPH (IR MPH) dosed three times daily in various studies. Especially, parent's preference of OROS MPH was better than IR MPH. The efficacy of MPH for academic achievement was equivocal. Long-term efficacy of OROS MPH was also inconclusive and further study is necessary.

Xenotransplantation, as a potential solution to the shortage of human organs, is associated with a number of concerns including immunologic rejection and xenogenic infection. While the pigs are considered the most suitable organ source for xenotransplantation, there is a potential public health risk due to zoonosis. Among the known porcine zoonotic microbes, Porcine Endogenous Retrovirus (PERV) is the most considerable virus. PERV belongs to the Gammaretrovirus and has been divided into three groups (A, B, and C). To characterize the gag of PERVs, we isolated the genomic DNAs from three pig breeds (Birkshire, Duroc, and Yorkshire) and two types of SPF miniature pigs. About 1.5 kb fragments covering full length of gag were amplified and cloned into T-vector. A total of 38 clones were obtained and sequenced. Nucleotide sequences were analyzed and phylogenetic trees were constructed from the nucleotide and deduced amino acids. PERV-A, -B and -C were present in the proportion of 47, 19 and 34%, respectively. Regardless of origin or subgroups, gag clones showed highly homology in nucleotide and deduced amino acid sequences. Deduced amino acids sequence alignments showed typical conserve sequences, Cys-His box and processing sites. Among analyzed clones, about 28% of isolates had the correct open reading frame. To test the functional expression of Gag protein, gag was subcloned into expression vector and confirmed its expression in HeLa cell. This research provides the fundamental information about molecular characteristics of gag gene and functional Gag protein related xenotropic PERVs.
