Abstract
OBJECTIVE To investigate the accuracy of artificial intelligence-assisted growth prediction using a convolutional neural network (CNN) algorithm and longitudinal lateral cephalograms (Lat-cephs). MATERIALS AND METHODS A total of 198 Japanese preadolescent children, who had skeletal Class I malocclusion and whose Lat-cephs were available at age 8 years (T0) and 10 years (T1), were allocated into the training, validation, and test phases (n = 161, n = 17, n = 20). Orthodontists and the CNN model identified 28 hard-tissue landmarks (HTL) and 19 soft-tissue landmarks (STL). The mean prediction error values were defined as 'excellent,' 'very good,' 'good,' 'acceptable,' and 'unsatisfactory' (criteria: 0.5 mm, 1.0 mm, 1.5 mm, and 2.0 mm, respectively). The degree of accurate prediction percentage (APP) was defined as 'very high,' 'high,' 'medium,' and 'low' (criteria: 90%, 70%, and 50%, respectively) according to the percentage of subjects that showed the error range within 1.5 mm. RESULTS All HTLs showed acceptable-to-excellent mean PE values, while the STLs Pog', Gn', and Me' showed unsatisfactory values, and the rest showed good-to-acceptable values. Regarding the degree of APP, HTLs Ba, ramus posterior, Pm, Pog, B-point, Me, and mandibular first molar root apex exhibited low APPs. The STLs labrale superius, lower embrasure, lower lip, point of lower profile, B', Pog,' Gn' and Me' also exhibited low APPs. The remainder of HTLs and STLs showed medium-to-very high APPs. CONCLUSION Despite the possibility of using the CNN model to predict growth, further studies are needed to improve the prediction accuracy in HTLs and STLs of the chin area.

Abstract
This study investigated depression and physical function as factors associated with nutritional risk in older adults living alone. The study included 2896 people 65 years or older who lived alone. Data were collected in South Korea between September and November 2020. Descriptive statistics, a chi-squared test, independent samples t-test, weighted multiple regression analysis, and binary logistic regression analysis were performed using IBM SPSS for Windows ver. 23.0. In this study, 44.8% of participants were in the nutritional risk group. Furthermore, 60.9% of those at risk for depression, 75.1% of those with instrumental activities of daily living (IADLs) dependency, and 59.1% of those with chewing limitations were at nutritional risk. The factors that increased nutritional risk in the weighted multiple regression analysis were depression (β = 0.27, p < 0.001), chewing limitations (β = 0.12, p < 0.001), IADL dependency (β = 0.09, p < 0.001), and basic physical movement (β = 0.04, p = 0.020). Binary logistic regression analysis showed that those with IADL dependency had a 2.59 times higher nutritional risk than those with IADL non-dependency (p < 0.001). The nutritional risk group had a higher risk of depression (2.01 times higher [p < 0.001]), chewing limitations (1.76 times higher [p < 0.001]), and basic physical movement limitations (1.35 times higher [p = 0.009]) than the good nutritional group. Therefore, nutritional screening is required of older individuals living alone. To mitigate nutritional risks, it is necessary to assess depression and physical function, including IADL dependency.

Abstract
OBJECTIVES In Korea, diabetes mellitus has a high disease burden, based on disability-adjusted life years. However, the disease burden is disproportionately distributed, with people with disabilities (PWD) experiencing higher rates of health disparities. Our study investigated long-term trends in diabetes prevalence and risk according to disability status, grade, and type. STUDY DESIGN Retrospective cohort study. METHODS Approximately 10 million individuals aged ≥30 years were included yearly from the National Health Information Database (NHID) and national disability registration data in Korea between 2008 and 2017, corresponding to 40 % of those aged ≥30 years in Korea. In 2017, 12, 975, 757 individuals were included; 5.5 % had disabilities. We estimated annual diabetes age-standardized prevalence and used multiple logistic regression analyses to estimate the odds of having diabetes in 2017, according to disability status, severity, and type. RESULTS Diabetes age-standardized prevalence consistently increased over 2008-2017 in PWD and people without disabilities. However, the prevalence increased more rapidly and was higher in all years among PWD, with widening disparities based on disability status. Additionally, diabetes prevalence was high in all years for specific subgroups, including women, individuals with intellectual or mental disabilities or autism, and individuals with severe disabilities, suggesting further disparities among PWD. CONCLUSIONS Our findings reveal health disparities between those with and without disabilities and among PWD subgroups. In addition to timely prevention, diabetes screening and management among PWD is vital. Public investment in improving disparities in the root causes of diabetes is essential, including health behaviours, healthcare utilization, and self-care.

Abstract
This study examined the effect of social interaction on life satisfaction in older adults. A total of 8188 participants were selected according to the inclusion criteria. SPSS Windows software (version 23.0) was used for statistical analyses. Data were analyzed using the independent samples t-test, chi-squared test, and multiple regression analysis with weights based on two age groups: 65-74 and ≥75 years. The results showed that social interaction factors influenced the life satisfaction of older adults. In the 65-74 age group, factors that statistically significantly increased life satisfaction were meeting children (β = 0.17, p < 0.001) and volunteer activities (β = 0.04, p = 0.007). In the ≥75 age group, factors that significantly increased life satisfaction were talking with friends (β = 0.11, p = 0.002), talking with children (β = 0.07, p = 0.013), using senior citizen community centers (β = 0.08, p = 0.001), and hobby club activities (β = 0.07, p = 0.001). In order to increase the life satisfaction of older adults, different ways to support social interactions need to be explored.

Abstract
PURPOSE/OBJECTIVE(S) Gut microbiome is known to be involved in antitumor immunotherapy and chemotherapy responses; however, few research has focused on the role of gut microbiome in the setting of concurrent chemoradiotherapy (CCRT). In this study, we investigated the tumor microbiome dynamics in patients undergoing neoadjuvant CCRT for locally advanced rectal cancer and sought to determine whether the diversity and composition of microbiome affect treatment response. MATERIALS/METHODS A total of 103 samples from 26 patients with locally advanced rectal cancer were collected and 16S ribosomal RNA amplicon sequencing was performed. All patients underwent neoadjuvant CCRT followed by surgical resection between 2008 and 2016. Samples were obtained from both tumor and normal rectal tissue at pre- and post-CCRT. According to the American Joint Committee on Cancer tumor regression grading (TRG) system, patients were divided into responders (TRG 0, 1) and non-responders (TRG 2, 3). We performed diversity, taxonomy, and network analyses to compare responders and non-responders. Then, we established the Bayesian network model to predict treatment response in patients with rectal cancer. RESULTS Overall, we detected 1260 microbial genera from 287 families, 132 orders, 56 classes, and 32 phyla in the bacteria kingdom. Between tumor and normal rectal tissues, there was no difference in microbial diversity and composition. On the other hand, there was a significant decrease in diversity and compositional alterations when comparing pre- and post-CCRT samples (all p<0.001). Ten patients (38.5%) were classified as responders and 16 patients (61.5%) were classified as non-responders. In both groups, CCRT significantly reduced microbial diversity and altered their composition, but it was more pronounced in non-responders. In taxonomic analysis of pre-CCRT samples, butyrate-producing bacteria were differentially enriched in responders. Meanwhile, in post-CCRT samples, opportunistic pathogen were overrepresented in non-responders. The network analysis revealed that butyrate-producing bacteria had strong interactions in responders, whereas opportunistic pathogen demonstrated strong interactions in non-responders (Pearson's coefficient>0.5). Finally, five microbes were selected as the optimal set for the response prediction model, which yielded an area under the curve value of 82.33%. CONCLUSION CCRT significantly changed the diversity and composition of microbiome, especially in non-responders. Several microbes might be related with treatment response. These findings highlight the potential of microbiome to play an important role as a biomarker in patients with rectal cancer. (NCT02533271).

Abstract
OBJECTIVES Current smoking rates for people with and without disabilities vary among countries. This study analyzed smoking behavior over 9 years in adult South Korean men with disabilities, according to disability severity and type, and in those without disabilities. STUDY DESIGN This was a cross-sectional study. METHODS This analysis was conducted using national disability registration data and national general health checkup data for 2009-2017. Age-standardized smoking behaviors were analyzed for each year according to the presence, severity, and type of disability. The odds of current smoking were determined by multivariate logistic regression after adjusting for sociodemographic and clinical variables. RESULTS The age-standardized smoking rate and average number of cigarettes for men with mild disabilities in the younger age group were 1.16 (43.0 vs 36.8%) and 1.05 (16.1 vs 15.3 cigarettes) times higher than in non-disabled men as of 2017. The highest smoking rate was observed in men with physical disabilities in the younger age. In the older age group, the highest smoking rate was that of men with intellectual or psychological disabilities. CONCLUSION Smoking behaviors remained poorest in men with disabilities, especially those with mild, physical, and intellectual/psychological disabilities. Public health policies should focus on people with disabilities to promote health, prevent secondary conditions, and reduce health disparities by implementing antismoking health policies.

Abstract
OBJECTIVE To summarize changes in recommendations for injection treatments for knee osteoarthritis (OA) in current clinical practice guidelines (CPGs) and to assess whether these changes have affected public interest according to Google data and content in YouTube videos. DESIGN A literature search to identify CPGs revised since 2019 that provide recommendations regarding the five intra-articular injection treatments for knee OA (corticosteroid [CS], hyaluronic acid [HA], stem cell [SC], platelet-rich plasma [PRP], and botulinum toxin [BT]) was conducted to assess perspective changes for each treatment. Data from Google Trends were examined to identify changes in search volume from 2004 to 2021 using a join-point regression model. Relevant YouTube videos were divided into those uploaded before and after changes in CPGs and compared according to degrees of recommendation for each treatment to identify the effect of changes in CPGs on video production. RESULTS All eight identified CPGs released after 2019 recommended HA and CS use. Most CPGs were the first to state a neutral or opposing stance concerning the use of SC, PRP, or BT. Interestingly, relative searches on Google for SC, PRP, and BT has increased greater than those for CS and HA. YouTube videos produced after CPGs changed continue to recommend SC, PRP, and BT as much as those produced before CPGs were revised. CONCLUSIONS Although knee OA CPGs have changed, public interest and healthcare information providers on YouTube have not reacted to this shift. Improved methods to propagate updates to CPGs warrant consideration.

Abstract
Background A significant amount of research has been conducted to establish the validity of acupuncture, and it has been demonstrated through animal disease model studies that acupuncture influences mitochondrial changes. However, to more accurately examine the mechanisms of acupuncture treatment effectiveness in pathological models, it is crucial to investigate changes in disease-free animals. Among various hypotheses regarding the effects of acupuncture on the body, we focused on the result that acupuncture stimulation is related to mitochondria. Objectives We examined the effects of acupuncture mitochondrial fission and fusionrelated mediators in disease-free Sprague Dawley (SD) rats' spleen meridian acupoints. Methods SD rats were divided into control, SP1, SP2, SP3, SP5, and SP9 acupuncture groups. Acupuncture was performed at each point for 10 minutes daily for four days. Peroxisome proliferator-activated receptor-gamma coactivator 1-α (PGC-1α) and fission protein 1 (Fis1) levels were evaluated using quantitative real-time polymerase chain reaction (qRT-PCR), while dynamin-related protein 1 (DRP1), optic atrophy-1 (OPA1), mitofusin-1 (MFN1), and mitofusin-2 (MFN2) levels were assessed via western blotting. Mitochondria protein concentrations and NADH dehydrogenase activity in spleen tissues were measured using enzyme-linked immunosorbent assay (ELISA). Results PGC-1α expression decreased in the SP1 (p < 0.01), SP5 (p < 0.05), and SP9 (p < 0.05) groups, while Fis1 expression increased in the SP1 (p < 0.01), SP5 (p < 0.01), and SP9 (p < 0.05) groups. DRP1, OPA1, MFN1, and MFN2 levels exhibited no significant changes. Mitochondrial protein concentrations decreased in the SP2 (p < 0.01), SP3 (p < 0.01), SP5 (p < 0.01), and SP9 (p < 0.01) groups, while NADH dehydrogenase activity decreased in the SP2 (p < 0.05) and SP9 (p < 0.05) groups. Conclusion Acupuncture at the SP9 acupoint influenced the mitochondrial fission pathway by modulating PGC-1α and Fis1 mediators in the rat spleen under non-disease conditions.

Abstract
BACKGROUND Glasgow Microenvironment Score (GMS) stratifies long-term survival into three groups based on tumour phenotype: peritumoural inflammation (Klintrup-Mäkinen (KM)) and tumour stroma percentage (TSP). However, it is not known if the location of disease recurrence is influenced by the GMS category. METHODS Seven hundred and eighty-three TNM I-III colorectal cancers (CRC) were included. GMS (GMS0-high KM; GMS1-low KM, low TSP; GMS2-low KM, high TSP) and cancer-specific survival (CSS), overall survival (OS) and disease recurrence were assessed using Cox regression analysis. RESULTS Of the 783 patients, 221 developed CRC recurrence; 65 developed local recurrence + systemic disease. GMS was independent for CSS (HR 1.50, 95% CI 1.17-1.92, p < 0.001) and OS (HR 1.23, 1.05-1.44, p = 0.01). Higher GMS category was associated with T-stage, N-stage, emergency presentation and venous invasion. GMS was independent for local+systemic recurrence (HR 11.53, 95% CI 1.45-91.85, p = 0.04) and distant-only recurrence (HR 3.01, 95% CI 1.59-5.71, p = 0.002). GMS 2 disease did not appear to have statistically better outcomes with adjuvant chemotherapy in high-risk disease. CONCLUSION Although confounded by a higher rate of T4 and node-positive disease, GMS 1 and 2 are associated with an increased risk of local and distant recurrence. GMS is an independent poor prognostic indicator for recurrent colorectal cancer. Higher GMS patients may benefit from enhanced postoperative surveillance.

Abstract
Abstract
Background
Elderly patients undergoing percutaneous coronary intervention (PCI) generally have a high risk of adverse clinical outcomes. We investigated the long-term clinical impact of PCI on coronary bifurcation disease in elderly patients in Korea and Italy.
Methods
From the BIFURCAT (comBined Insights from the Unified RAIN and COBIS bifurcAtion regisTries) data, we evaluated 5,537 patients who underwent PCI for coronary bifurcation disease. The primary outcome was major adverse cardiac events (MACEs), defined as the composite of target vessel myocardial infarction, target lesion revascularisation, and stent thrombosis. Kaplan–Meier estimates and Cox proportional hazard models were used to compare elderly patients (aged ≥75 years) and younger patients (aged <75 years).
Results
A total of 1,415 patients (26%) were aged ≥75 years. Elderly patients were more frequently female, had higher rates of hypertension and chronic kidney disease (CKD), and presented more frequently with left main (LM) disease. After a median follow-up of 2.1 years, MACEs were comparable between elderly and younger patients. In multivariable analysis, old age was not an independent predictor of MACEs (p=0.977). In elderly patients, CKD and LM disease were independent predictors of MACEs, whereas in younger patients, hypertension, diabetes, CKD, reduced left ventricular ejection fraction, LM disease, and two-stent strategy usage were independent predictors.
Conclusions
Elderly patients who underwent coronary bifurcation PCI with second-generation drug-eluting stents demonstrated similar clinical outcomes to those of younger patients. Both CKD and LM disease were independent predictors of MACEs, regardless of age after coronary bifurcation PCI.

Abstract
Abstract
Background
Diabetes mellitus (DM) is highly prevalent among individuals hospitalized with acute myocardial infarction (AMI) and is associated with increased risk for cardiovascular complications and short-term and long-term mortality. However, most existing data are from older patients. Little is known about the incidence of diabetes in individuals who experience AMI at a young age. Whether the presence of DM is associated with worse outcomes in these patients is not clear.
Purpose
To test the hypothesis that the impact of DM on clinical outcomes after AMI can vary by age.
Methods
A total of 12,600 AMI patients from the Korea Acute Myocardial Infarction Registry-National Institute of Health (KAMIR-NIH) between November 2011 and December 2015 was classified into young (n=3,590 [28.5%]) and elderly (n=9,010 [71.5%]). Those less than 55 years of age were considered young. We performed comparisons of baseline characteristics, in-hospital treatments, and long-term clinical outcomes between patients with and without diabetes after stratification according to age group.
Results
The prevalence of diabetes mellitus was 26.5% in the young AMI group. In the multivariable-adjusted model of the entire cohort, diabetes mellitus was associated strongly with 3-year all-cause mortality (12.6% vs. 6.8%; adjusted hazard ratio [HR], 1.318; 95% confidence interval [CI], 1.138–1.526; P<0.001). When the entire cohort was subdivided into two age groups, young diabetic patients showed a 107.0% higher mortality rate than those without diabetes (adjusted HR, 2.070; 95% CI, 1.150–3.724; P=0.015). Meanwhile, elderly diabetic patients had a 25.3% higher risk of mortality than non-diabetic patients (adjusted HR, 1.253; 95% CI, 1.076–1.459; P=0.004). The interaction of diabetes with age was significant (adjusted P for interaction = 0.008).
Conclusion
DM is not uncommon in younger AMI patients, and the relative risk of long-term mortality is significantly higher in young patients than in older counterparts. More aggressive treatments are needed to prevent future cardiovascular events in younger patients after AMI.

Abstract
Abstract
Background
Central blood pressure and central pulse pressure have a better correlation with the risk of cardiovascular disease compared to those of peripheral measurement. In a previous study, a second-generation beta-blocker showed poor CBP-lowering effects. However, the effect on CBP by third-generation beta-blockers is not fully elucidated. Thus, this randomised study investigated whether nebivolol-based hypertension treatment may confer advantages over telmisartan, an angiotensin II receptor-blocker, in reducing CBP.
Methods
This was a prospective, randomised, multicentre, open-label, controlled trial that evaluated 98 hypertensive patients. Patients received either nebivolol- (N=49) or telmisartan-based (N=49) treatment for hypertension for 12 weeks with a target BP of ≤140/80. The primary outcome was the difference in change from baseline central systolic BP (cSBP) after 12 weeks.
Results
There were no significant differences between the two groups in baseline central and peripheral SBP. The mean change in cSBP from baseline (ΔcSBP) was −17.2±3 mmHg for nebivolol group (P<0.001) and −29.9±3 mmHg for telmisartan group (P<0.001). The difference in ΔcSBP between the two groups was significant (12.7mmHg, 95% confidence interval [CI], 4.13 to 21.2; P=0.004). Peripheral SBP (pSBP) decreased less in nebivolol group compared to telmisartan group (−18.0±3 in nebivolol group vs. −26.3±3 in telmisartan group, P=0.032). After adjusting for reduction in pSBP, reduction in cSBP was higher in telmisartan group compared to nebivolol group, as shown by the ratio of changes in cSBP and pSBP (ΔcSBP/ΔpSBP; 0.67 for nebivolol group vs. 1.11 for telmisartan group, P=0.080), albeit without statistical significance.
Conclusions
Nebivolol-based hypertension treatment may have less potent CBP-lowering effects compared to telmisartan. However, larger-scale studies are warranted to further elaborate our findings.

Abstract
Abstract
Background
A limitation of the current guidelines of the timing of invasive coronary angiography (ICA) for patients with non-ST-segment elevation (NSTE) acute coronary syndrome is based on randomization time. So far, no study has reported the clinical outcomes of invasive strategy timing based on the time of symptom onset. Herein, we aimed to investigate the effect of invasive strategy timing from the time of symptom onset on the 3-year clinical outcomes of patients with NSTE myocardial infarction (MI).
Methods and results
Among 13,104 patients from the Korea Acute Myocardial Infarction Registry-National Institutes of Health, we evaluated 5,856 patients with NSTEMI. The patients were categorized according to symptom-to-catheter (StC) time (<48 h and ≥48 h). The primary outcome was 3-year all-cause mortality, and the secondary outcome was a 3-year composite of all-cause mortality, recurrent MI, and hospitalization for heart failure. Overall, 3,919 (66.9%) patients were classified into the StC time <48 h group. This group had lower all-cause mortality than the StC time ≥48 h group (7.3% vs. 13.4%, p<0.001). The continuous association of StC time and risk of primary and secondary endpoints showed shorter StC time (reference: 48 h), and lower adjusted hazard ratio reduction was observed. In multivariable analysis, independent predictors of delayed ICA were older age, non-specific symptoms, no use of emergency medical services, no ST-segment deviation, chronic kidney disease, and Global Registry of Acute Coronary Events score >140.
Conclusion
Early invasive strategy based on the StC time improves all-cause mortality in patients with NSTEMI.

Abstract
This study examined which residential conditions increase older adults’ life satisfaction at home. We used data from 8903 participants over 65 years old who did not need help in their daily lives from a 2020 survey of older adults conducted by the Korea Institute for Health and Social Affairs. Data analysis was conducted using descriptive statistics, independent sample t-test, Pearson correlation analysis, and hierarchical multiple regression with weights. The final model explained 34.2% of life satisfaction in old age. Residential conditions that increased life satisfaction the most in old age were the community environment (β = 0.16, p < 0.001) and satisfaction with the house (β = 0.15, p < 0.001). Other conditions that significantly affected life satisfaction were safety (β = 0.08, p < 0.001), interaction with neighbors (β = 0.08, p < 0.001), distance from children or relatives (β = 0.08, p < 0.001), frequency and route of public transportation (β = 0.05, p < 0.001), and abundance and distance of green spaces (β = 0.02, p = 0.031). Housing welfare policies should consider these results to increase life satisfaction for an increasingly aging population. Moreover, these data can be used to design age-friendly community environments.

Abstract
University life is challenging for students, given the college life adjustment, life stress, career barriers, and career decision-making self-efficacy required. COVID-19 has made this even more complex. This study investigated the relationships among these factors in college students who experienced COVID-19. Data were collected using an online cross-sectional structured survey of 1242 university students from December 2020 to January 2021. Data were analyzed via independent-sample t-tests, one-way ANOVAs, Pearson’s correlation coefficient, multiple regression, and logistic regression, using SPSS. College life adjustment was significantly correlated with life stress (r = −0.255, p < 0.001), career barriers (r = −0.429, p < 0.001), and career decision-making self-efficacy (r = 0.531, p < 0.001). The regression analysis showed that career barriers, career decision-making self-efficacy, and grade level had a total explanatory power of 33.7% for college life adaptation. The logistic regression analysis showed that the odds ratio (OR) of career barriers being low in the group with a high college life adaptation score was 2.045 (p < 0.001), and the OR of career decision-making self-efficacy being high was 4.107 (p < 0.001), as compared to the group with a low score. To increase college students’ adaptation to college life, career support programs that improve career barriers and career decision-making self-efficacy should be developed.

Abstract
Senescent cells accumulate in several tissues during ageing, including the skin, and contribute to the functional decline of the skin via the senescence-associated secretory phenotypes (SASPs) 1 . Due to the potential negative effects of SASPs during the ageing process, drugs that selectively target senescent cells or SASPs represent an important therapeutic strategy to delay skin ageing. The selective induction of cell death specifically to kill senescent cells using drugs, referred to as senolytics, is a main approach to achieve this strategy 2 .

Abstract
OBJECTIVE Complex regional pain syndrome (CRPS) is caused by injuries from fracture after trauma and orthopaedic surgical procedures in the hind limbs. The symptoms of CRPS include warmth, pain, allodynia, and hyperalgesia. It is known that 5-hydroxytryptamine 3 (5-HT3) receptors contribute to hyperalgesia, but their role has not yet been fully elucidated. This study investigated the mechanism of pain relief when a 5-HT3 receptor antagonist was administered in a CRPS animal model. MATERIALS AND METHODS To establish a CRPS animal model, 10-week-old Sprague-Dawley rats were used in the experiment. On the fourth week post tibial fracture surgery, we performed the von Frey test to measure mechanical allodynia. After performing behavioural tests, we collected blood and tissue samples after sacrificing the animals. Enzyme-linked immunosorbent assay and western blot were also performed. RESULTS The experimental tibia fracture model-induced CRPS animals elicited increased 5-HT3 receptor expression, and the 5-HT transporter was decreased in the brain stem after 4 weeks of surgical intervention. Additionally, in CRPS-induced animals, both the concentration of substance P and the level of interleukin 6 were increased peripherally and centrally. Treatment with the 5-HT3 receptor antagonist, ramosetron, exerted an analgesic effect in the paw withdrawal test and was dependent on the attenuation of the 5-HT3 receptor population with inflammatory pain mediators. CONCLUSIONS These data suggest that treatment with the 5-HT3 receptor antagonist, ramosetron, in experimental CRPS animal models alleviated pain-related behaviours and may be a new therapeutic option or potential therapeutic agent for patients with CRPS.

Abstract
BACKGROUND There remain concerns about the safety and functional benefit of laparoscopic pylorus-preserving gastrectomy (LPPG) compared with laparoscopic distal gastrectomy (LDG). This study evaluated short-term outcomes of a randomized clinical trial (RCT) comparing LPPG with LDG for gastric cancer. METHODS The Korean Laparoendoscopic Gastrointestinal Surgery Study (KLASS)-04 trial was an investigator-initiated, open-label, parallel-assigned, superiority, multicentre RCT in Korea. Patients with cT1N0M0 cancer located in the middle third of the stomach at least 5 cm from the pylorus were randomized to undergo LPPG or LDG. Participants, care givers and those assessing the outcomes were not blinded to group assignment. Outcomes were 30-day postoperative morbidity rate and death at 90 days. RESULTS Some 256 patients from nine institutions were randomized (LPPG 129 patients, LDG 127 patients) between July 2015 and July 2017 and outcomes for 253 patients were analysed. Postoperative complications within 30 days were seen in 19.3 and 15.5 per cent in the LPPG and LDG groups respectively (P = 0·419). Postoperative pyloric stenosis was observed in nine (7.2 per cent) and two (1·5 per cent) patients in the LPPG and LDG groups (P = 0·026) respectively. In multivariable analysis higher BMI was a risk factor for postoperative complications (odds ratio 1·17, 95 per cent c.i. 1·04 to 1·32; P = 0·011). Death at 90 days was zero in both groups. CONCLUSION Postoperative complications and mortality was comparable in patients undergoing LPPG and LDG. Registration number: NCT02595086 (http://www.clinicaltrials.gov).

Abstract
The purpose of this study was to investigate the relationship between nursing students’ acceptance intention of a smart device, information literacy, and problem-solving confidence to explore the factors that may improve nursing students’ problem-solving confidence. Data were collected from 450 nursing students between July and August 2019 in two cities in Korea. The results showed that there is a positive correlation between problem-solving confidence and acceptance intention (r = 0.353, p < 0.001) and between problem-solving confidence and information literacy (r = 0.501, p < 0.001). Further, participants with high acceptance intention of a smart device and information literacy scores had significantly higher problem-solving confidence (t = 5.447, p < 0.001; t = 10.072, p < 0.001) than participants with low acceptance intention. In addition, in the logistic regression the odds ratio between the acceptance intention of a smart device, information literacy, and problem-solving confidence groups was odds ratio 2.071 (p < 0.001, CI: 1.412–3.037) and odd ratio 4.966 (p < 0.001, CI: 3.298–7.477). To improve nursing students’ problem-solving confidence, educational strategies should be developed to build information experience and information utilization capabilities.

Abstract
BACKGROUND: Cardiovascular disease is one of the main causes of mortality in patients with chronic obstructive pulmonary disease (COPD), and atherosclerosis is a cause of cardiac comorbidities in COPD. However, it is not clear whether airflow limitation is associated with atherosclerosis irrespective of smoking.OBJECTIVE: To investigate whether airflow limitation is independently associated with vascular stiffness.METHODS: We enrolled 18 893 participants (male 70.5%; mean age 47.5 ± 9.8 years; never smokers 44.2%) who underwent spirometry and brachial-ankle pulse wave velocity (baPWV) as part of a standard health examination at Ajou University Hospital, Suwon, South Korea, from January 2010 to December 2015.We defined vascular peripheral atherosclerosis as baPWV ≥ 1400 cm/s and airflow limitation as pre-bronchodilator ratio of forced expiratory volume in 1 sec (FEV1) to forced vital capacity (FVC) <70%.RESULTS: Mean baPWV was higher in subjects with airflow limitation (1477.6 ± 331.7 cm/sec, n = 638) than in those without airflow limitation (1344.1 ± 231.8 cm/sec, n = 18255, P < 0.001). In multivariate logistic regression analysis, the following were independent predictors associated with peripheral atherosclerosis (P < 0.05): age, male sex, fasting serum glucose, mean blood pressure, serum leukocyte count, serum low density lipoprotein level and FEV1.CONCLUSION: Airflow limitation was an independent predictor of vascular stiffness irrespective of smoking history, which suggests that airflow limitation is linked with atherosclerosis.
