Background/Aims: The aim of this study was to compare antimicrobial resistance, clinical features, and outcomes of community-onset Escherichia coli (COEC) and Klebsiella pneumoniae (COKP) bacteremia. Methods: The medical records of patients diagnosed with E. coli or K. pneumoniae bacteremia in the emergency department of a 750-bed secondary care hospital in Daegu, Korea from January 2010 to December 2016 were retrospectively reviewed. Results: A total of 866 patients with COEC bacteremia and 299 with COKP bacteremia were enrolled. COEC bacteremia, compared to COKP bacteremia, had higher rates of 3rd generation cephalosporin (3GC) (18.8% vs. 8.4%, p < 0.001) and f luoroquinolone (FQ) (30.4% vs. 8.0%, p < 0.001) resistance. The patients with COKP bacteremia had higher Charlson comorbidity indices (CCI) (1.8 ± 2.0 vs. 1.5 ± 1.8, p = 0.035), Pittsburgh bacteremia scores (PBS) (2.0 ± 2.6 vs. 1.3 ± 1.8, p < 0.001), and 30-day mortality (14.44% vs. 8.8%, p = 0.008) than the patients with COEC bacteremia. Age younger than 70 years, male sex, polymicrobial infections, pneumonia, intra-abdominal infection, PBS ≥ 2, and Foley catheter insertion were independent predictive factors for COKP bacteremia compared to COEC bacteremia in the multivariate analysis. CCI, PBS, and intensive care unit admission were independent risk factors for 30-day mortality in the multivariate analysis. Conclusions 3GCs and FQs are still useful for the empirical treatment of patients with probable COKP bacteremia. The patients with COKP bacteremia had worse outcomes because of its greater severity and more frequent underlying comorbidities.

Purpose: This study aimed to evaluate and compare the quality of total mesorectal excision (TME) and disease-free and overall survival rates between robotic and laparoscopic surgeries for rectal cancer. Methods: From January 2015 to December 2018, 234 patients underwent curative robotic or laparoscopic surgery for rectal cancer at two centers. Ultimately, 201 patients were enrolled. To control for different demographic factors in the two groups, propensity score matching was used at a 1:1 ratio. Propensity scores were generated with the baseline characteristics, including age, sex, body mass index, American Society of Anesthesiologists score, previous abdominal surgery, tumor location, preoperative chemotherapy, and preoperative radiation. Finally, 134 patients were matched with 67 patients in the robotic surgery group and 67 patients in the laparoscopic surgery group. Results: There was no significant difference in the pathologic stages between the robotic and laparoscopic surgery groups. Distal margin involvement was only observed in the robotic surgery group (1/67, 1.5%). Circumferential resection margin involvement was not different between the robotic surgery and laparoscopic surgery groups (3/67 [4.5%] and 4/67 [6.0%], respectively, P = 1.000). The quality of TME (complete, nearly complete, and incomplete) was similar between the robotic surgery and laparoscopic surgery groups (88.0%, 6.0%, 6.0% and 79.1%, 9.0%, 11.9%, respectively, P = 0.358). The disease-free and overall survival rates were not significantly different between the groups. Conclusion The quality of TME and disease-free and overall survival rates between the two surgeries were similar. There was no oncologic advantage of robotic surgery for rectal cancer compared to laparoscopic surgery.

Background: Patients with Parkinson’s disease (PD) experience both motor and non-motor symptoms, including dysphagia. Although PD is closely associated with dysphagia, the prevalence or risk of dysphagia in PD is unclear, especially in Asian countries. Methods: The prevalence of PD and dysphagia with PD in the general population was analyzed using the Korean National Health Insurance Service (NHIS) database. The prevalence per 100,000 persons of PD and dysphagia with PD from 2006 to 2015 was analyzed in the general population aged ≥ 40 years. Patients newly diagnosed with PD between 2010 and 2015 were compared with those without PD. Results: The prevalence of PD and dysphagia in patients with PD increased continuously during the study period and was highest in the ninth decade of life. The percentage of patients with dysphagia in patients with PD increased with age. Patients with PD showed an adjusted hazard ratio of 3.132 (2.955–3.320) for dysphagia compared to those without PD. Conclusion This nationwide study showed increasing trends in the prevalence of PD and dysphagia among patients with PD in Korea between 2006 and 2015. The risk of dysphagia was three times higher in patients with PD than that in those without PD, highlighting the importance of providing particular attention.

Ticks were collected from 35 animals from 5 provinces and 3 metropolitan cities during 2012. Ticks also were collected by tick drag from 4 sites in Gyeonggi-do (2) and Jeollabuk-do (2) Provinces. A total of 612 ticks belonging to 6 species and 3 genera were collected from mammals and a bird (n=573) and by tick drag (n=39). Haemaphyalis longicornis (n=434) was the most commonly collected tick, followed by H. flava (158), Ixodes nipponensis (11), Amblyomma testudinarium (7), H. japonica (1), and H. formosensis (1). H. longicornis and H. flava were collected from all animal hosts examined. For animal hosts (n>1), the highest Tick Index (TI) was observed for domestic dogs (29.6), followed by Siberian roe deer (17.4), water deer (14.4), and raccoon dogs (1.3). A total of 402 H. longicornis (adults 86, 21.4%; nymphs 160, 39.8%; larvae 156, 38.9%) were collected from wild and domestic animals. A total of 158 H. flava (n=158) were collected from wild and domestic animals and 1 ring-necked pheasant, with a higher proportion of adults (103, 65.2%), while nymphs and larvae only accounted for 12.7% (20) and 22.2% (35), respectively. Only 7 A. testudinarium were collected from the wild boar (6 adults) and Eurasian badger (1 nymph), while only 5 I. nipponensis were collected from the water deer (4 adults) and a raccoon dog (1 adult). One adult female H. formosensis was first collected from vegetation by tick drag from Mara Island, Seogwipo-si, Jeju-do Province.

BACKGROUND/OBJECTIVES: South Korean's sodium consumption level is more than twice the upper limit level suggested by the WHO. Steep increases in the prevalence of hypertension and cardiovascular disease in Korea necessitate more effective sodium reduction programs. This study was conducted in order to compare sodium intake-related eating behaviors and key psychosocial factors according to age group and gender. SUBJECTS/METHODS: Using an online survey, a total of 1,564 adults (20-59 years old) considered to be geographically representative of South Korea were recruited and surveyed. The major outcomes were perceived behaviors, knowledge, intentions, and self-efficacy related to sodium intake. RESULTS: The results show that perceived behavior and level of self-efficacy related to low sodium consumption differed by age and gender. Female participants showed better behavior and intention towards low sodium intake than male counterparts. Young participants in their 20s showed the lowest intention to change their current sodium intake as well as lowest self-efficacy measures. CONCLUSIONS: Future sodium reduction interventions should be developed with tailored messages targeting different age and gender groups. Specifically, interventions can be planned and implemented at the college level or for workers in their early career to increase their intention and self-efficacy as a means of preventing future health complications associated with high sodium intake.

PURPOSE: A descriptive correlational study was designed to examine the relationship of trait anger and anger expression to blood pressure, cholesterol, and depression in middle-aged Korean men. In addition, this study investigated the mediating effect of social support in relation to anger and other variables. METHODS: Two hundred and ninety nine men aged 40 to 64 years were recruited from a health center at K University Hospital located in Ansan City, Kyungki province, Korea. The instruments used were Spielberger's state trait anger expression inventory-the Korean version for trait anger and anger expression, Beck's depression inventory for depression, and a Personal resource questionnaire for perceived social support. RESULTS: Men with high trait anger showed significantly higher systolic blood pressure(BP) and diastolic BP. The level of cholesterol did not have a significant relationship with trait anger and anger expression. The severity of depression was significantly higher in men with high trait anger or more frequent uses of anger-in or anger-out. The perceived social support had a significant mediating effect in relation to trait anger and depression. CONCLUSIONS: Various nursing interventions for managing anger or improving social support need to be developed in a future study.

PURPOSE: Seasonal variations in asthma exacerbation (AE) are associated with respiratory virus outbreaks and the return of children to school after vacation. This study aims to elucidate the period, phase, and amplitude of seasonal cycles of AE in 5 different age groups with regard to rhino- and influenza virus epidemics in Korea. METHODS: The number of daily emergency department (ED) visits for AE in all age groups of Korea and the nationwide weekly incidence of rhino- and influenza virus, were obtained for 2008-2012. Fourier regression was used to model rhythmicity, and the Cosinor method was used to determine the amplitude and phase of the cycles in each age group. The cross-correlation function (CCF) between AE and the rhino- and influenza virus epidemics was also calculated. RESULTS: There were 157,559 events of AE (0.62 events/1,000 individuals/year) during the study period. There were spring and fall peaks of AE in children and adults, but only 1 winter peak in the elderly. The amplitude of the AE peak in infants was higher in spring than in fall (9.16 vs 3.04, P<0.010), and the fall peak was approximately 1 month later in infants than in school children (October 11 vs November 13, P<0.010). The association between AE and rhinovirus was greatest in school children (rho=0.331), and the association between AE and influenza virus was greatest in those aged ≥60 years (rho=0.682). CONCLUSIONS: The rhythmicity, amplitude, and phase of the annual cycle of AE differed among different age groups. The patterns of AE were related to the annual rhino- and influenza virus epidemics.

Marine algae are rich sources of various biologically active compounds with potential pharmaceutical properties. In the present study, we investigated the inhibitory effects of Plocamium telfairiae extract (PTE) on proinflammatory cytokine production in bone marrow-derived macrophage (BMDMs) and dendritic cells (BMDCs). PTE pre-treatment in LPS-stimulated BMDMs and BMDCs showed a strong inhibition on interleukin (IL)-12 p40, IL-6, and tumor necrosis factor (TNF)-alpha production as compared to non-treated controls. PTE pre-treatment showed significant inhibition on phosphorylation of mitogen-activated protein kinases and degradation of inhibitor of kappa B (IkappaBalpha). Taken together, these results suggest that PTE may have potential anti-inflammatory property and hence, warrant further studies concerning the potentials of PTE for medicinal purpose.

Purpose: This study aimed to evaluate the cumulative recurrence rate and risk factors for recurrent abdominal wall endometriosis (AWE) after surgical treatment. Materials and Methods: A retrospective cohort study was conducted at a single gynecological surgery center between January 2004 and December 2020. Patients who were surgically treated and followed up for at least 6 months after surgery were selected. Results: Eighteen patients with pathologically diagnosed AWE were included in this study. The median follow-up duration was 22.5 months (range, 6–106). The median age was 37 years (range, 22–48), and 33.3% of the patients were nulliparous. Among the patients included in our study, 55.6% complained of a mass with cyclic pain, and 27.8% had a palpable mass. In addition, 22.2% of patients experienced recurrence with 17.5±9.7 months of mean time to recurrence. The cumulative recurrence rates at 24 and 60 months after surgical treatment of AWE were 23.8% and 39.1%, respectively. There were no statistically significant risk factors for the recurrence of AWE, including postoperative medical treatment. Conclusion The recurrence rate of AWE appears to be correlated with the follow-up duration. There was no statistically significant risk factor for the recurrence of AWE. Unlike ovarian endometriosis, postoperative hormonal treatment does not seem to lower the recurrence of AWE. The findings of the current study may help healthcare providers in counselling and managing patients with AWE.
