ABSTRACT
BACKGROUND/OBJECTIVES@#In the Republic of Korea, “Healthy Restaurant for Sodium Reduction (HRSR)” project have been designated as one of the representative policies for sodium intake reduction. However, as of 2021, only 879 restaurants, less than 0.1% of all restaurants, had been designated. Therefore, to increase the participation of restaurants in this policy, it is necessary to examine the in-depth perception and experience of participants and non-participants in the HRSR.MATERIALS/METHODS: Two focus group discussions were conducted for HRSR project participants and non-participants. @*RESULTS@#A total of 260 semantic units were derived from the 2 groups. The units were further classified into 5 upper categories and 11 subcategories. All the study participants knew the importance of low sodium intake, but they had little information on HRSR project.Various attempts have been made to encourage low sodium practice in restaurants, and the participants reported that the amount of salt used in their restaurants currently is reduced compared to that used in the past. However, they were worried about customers’ complaints about the low sodium in their diet and the insignificant beneficent associated with the policy, which makes restaurant owners reluctant to participate in this policy. All the participants agreed on the urgent need for the improvement of public awareness of low-sodium diets and for substantive government support for HRSR. @*CONCLUSION@#This study concluded that strategies such as more active publicity for the practice of sodium reduction in restaurants, identification of approaches to dispel the perception that low-salt diet is not tasty, and development of plans to increase the sale of food in of HRSR, are needed.
ABSTRACT
Recurrent meningitis is defined as more than one episode of meningitis that is separated by an entire recovery period. Causes of recurrent meningitis include anatomical defects, immune deficiency, and parameningeal infections. A thorough investigation of the underlying causes of recurrent meningitis is required for proper treatment. Herein we report a case of recurrent bacterial meningitis caused by osteomyelitis of the odontoid process.
ABSTRACT
Objective@#Studies on gait and autonomic dysfunction have been insufficient so far, particularly de novo Parkinson’s disease (PD). The aim of this study was to identify the association between gait dynamics and autonomic dysfunction in patients with de novo PD. @*Methods@#A total 38 patients with de novo PD were retrospectively included in this study. Details of patients’ dysautonomia were assessed using the Scales for Outcomes in Parkinson’s Disease-Autonomic Dysfunction (SCOPA-AUT). For assessment of gait, a computerized gait analysis was performed using the GAITRite system for forward gait and backward gait. High SCOPA-AUT score (PD-HSAS) group and low SCOPA-AUT score (PD-LSAS) group were identified according to their SCOPA-AUT scores. @*Results@#Nineteen (50%) patients with high SCOPA-AUT scores above median value (12.5) were assigned into the PD-HSAS group and others were assigned to the PD-LSAS group. Compared with the PD-LSAS group, the PD-HSAS group exhibited slower gait, shorter stride, decreased cadence, increased double support phase, decreased swing phase, and increased variability in swing time. Total SCOPA-AUT score showed significantly positive correlations with gait variability and instability but a negative correlation with gait hypokinesia. In subdomain analysis, urinary dysautonomia was highly associated with impairment of gait dynamics. All significant results were found to be more remarkable in backward gait than in forward gait. @*Conclusion@#Our findings suggest that alteration in gait dynamics, especially backward gait, is highly associated with autonomic dysfunction in patients with de novo PD.
ABSTRACT
Lentinus edodes contains functional metabolites such as polysaccharopeptides, lectins, and secondary metabolites. Fermented soybean paste is representative fermented materials in Korea, and is gradually increasing due to various biological activities. In the present study, ethanol extracts of fermented products with/without L. edodes were designated as SPL and SP, and prepared to develop safer and therapeutic functional foods with antioxidant and anti-inflammatory activities for treatment of inflammatory disorders. SP and SPL extracts exhibited antioxidant effects via inhibiting radical activities. Inflammatory mediators, nitric oxide (NO), prostaglandin E2 (PGE2 ), interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor (TNF)-α, and inducible nitric oxide synthase (iNOS) production and nuclear factor-kappa B (NF-κB) activation were down-regulated by two extracts. SPL extract more strongly enhanced the antioxidant and anti-inflammatory activities than SP extract. Its’ activities shown more longer fermentation period and more strong inhibitory effects. Taken together, our results suggested that fermented product with medicinal plant has synergic effect and SPL can be a potential candidate for treatment of inflammatory bowel diseases.
ABSTRACT
Purpose@#The purpose of this study was to investigate the clinical practice patterns of Korean obstetricians and gynecologists the diagnosis and management of hypertensive disease in pregnant women. @*Methods@#From April 2015 to October 2015, questionnaire was distributed via email to obstetricians who were members of the Society for Maternal and Fetal Medicine. The survey consisted of 37 questions in 6 categories. Responses to the questions on the management of hypertensive disorders of pregnancy, from diagnosis to treatment, were evaluated. @*Results@#A total of 93 obstetricians and gynecologists responded to the survey. High blood pressure was allocated the highest priority as an index mainly used when deciding to hospitalize patients with hypertensive disease during pregnancy, followed by pregnancy symptoms, proteinuria, and blood test results. Calcium channel blocker (CCB) for oral administration and hydralazine for injection were preferred as antihypertensive drugs mainly used to control severe hypertension. Regarding the delivery method for hypertensive disease during pregnancy, in cases of preeclampsia, 63% of the respondents chose the delivery method according to the cervical status, and in cases of hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome and eclampsia, which increased in severity, 52% and 31% responded that the delivery method was determined according to the cervical status, respectively. In cases of mild preeclampsia, the 70% of respondents preferred 37–38 weeks of gestation for the delivery time. Regarding the use of aspirin in patient with hypertension during pregnancy, 52% of the respondents occasionally administered aspirin, and in patients with a history of hypertensive disease during pregnancy, only 43% were administered prophylactic aspirin. @*Conclusion@#Domestic obstetricians regarded blood pressure as the most meaningful factor when treating women with hypertension during pregnancy and considered blood pressure control as important. The preferred antihypertensive agents were oral CCB and hydralazine injections, and the choice of delivery method was determined according to the condition of the cervix and severity of the disease. Even in women with high risk factors for preeclampsia, prophylactic aspirin was administered in as low as 50%, of patients, possibly may due to the absence of domestic guidelines for aspirin use during pregnancy. Korean guidelines for prophylactic aspirin administration during pregnancy is needed based on additional research on the efficacy of aspirin for domestic women in the future.

ABSTRACT
This study investigated therapeutic candidates with anti-inflammatory potential among traditional dietary ingredients targeting inflammatory bowel disease (IBD). Both Avena sativa and traditional fermented products, such as Korean soy paste, are popular health foods. We investigated the anti-inflammatory effects of soy paste combined with A. sativa (KDA), compared with soy paste without A. sativa (KD) by evaluating the expression of pro-inflammatory cytokines in lipopolysaccharide-stimulated RAW264.7 mouse macrophages and HT-29 human colon epithelial cells. KDA significantly inhibited the production of nitric oxide (NO) and downregulated the pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α in lipopolysaccharide (LPS)-induced RAW264.7 cells. In another in vitro experiment involving LPS-stimulated HT-29 cells, KDA suppressed the levels of IL-8, which is the chemokine elevated in IBD. In addition, KDA exhibited anti-oxidative properties, such as 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and 2,2'-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical scavenging activity. Our findings revealed that A. sativa combined with soy paste exhibits a synergistic anti-inflammatory and anti-oxidant effect following fermentation.These results suggest that KDA may be used as a potential anti-inflammatory therapy against IBD.
ABSTRACT
Citrus junos seeds (CS) have been traditionally used for the treatment of cancer and neuralgia. They are also used to manufacture edible oil and cosmetic perfume. A large amount of CS shells without oil (CSS) are discarded after the oil in CS is used as foods or herbal remedy. To efficiently utilize CSS as a by-products, it needs to be studied through chemical analysis. Therefore, we developed an ultra-performance liquid chromatography (UPLC)–diode array detection (DAD) method for simultaneous determination and quantitative analysis of five components (two flavonoids and threes limonoids) in CSS. A Waters Acquity UPLC HSS T3 column C18 (2.1 × 100 mm, 1.8 μm) was used for this separation. It was maintained at 40 oC. The mobile phase used for the analysis was distilled water and acetonitrile with gradient elution. To identify the quantity of the five components, a mass spectrometer (MS) with an electrospray ionization (ESI) source was used. The regression equation showed great linearity, with correlation coefficient ≥ 0.9912. Limits of detection (LOD) and limits of quantification (LOQ) of the five compounds were 0.09 – 0.13 and 0.26 – 0.38 μg/mL, respectively. Recoveries of extraction ranged from 97.45% to 101.91%. Relative standard deviation (RSD) values of intra- and inter-day precision were 0.06 – 1.15% and 0.19 – 0.25%, respectively. This UPLC–DAD method can be validated to simultaneously analyze quantities of marker flavonoids and limonoids in CSS.
ABSTRACT
We aimed to identify risk factors for falls in patients with de novo Parkinson’s disease (PD). Methods Forty-six patients with de novo PD were retrospectively included in the study. We assessed details on the patients’ motor symptoms as well as non-motor symptoms using several representative scales for global cognition, depression, fatigue, and dysautonomia. Fallers and non-fallers were identified according to their history of falls during the preceding year. Results Twenty-two patients (45.8%) with de novo PD had a history of falls. Compared with the non-faller group, the faller group exhibited higher scores for postural instability/gait difficulty (PIGD), anxiety, fatigue, total dysautonomia, gastrointestinal dysfunction, and thermoregulatory dysfunction. Moreover, logistic regression analysis showed that falling was positively correlated with anxiety and gastrointestinal symptoms but negatively associated with the tremor scores. Conclusion Our findings suggest that falling in patients with de novo PD is significantly associated with PIGDon-tremor symptoms, anxiety, and gastrointestinal dysfunction.
ABSTRACT
Objective@#This study identified the distribution of lymphocele, as well as the factors associated with lymphocele formation, in patients undergoing pelvic and/or para-aortic lymph node dissection (PLND and/or PALND) for gynecologic malignancies. @*Methods@#This study was retrospective, and data were collected from patients who underwent surgical procedures including lymphadenectomy due to gynecologic malignancies from March 2013 to May 2016. Lymphocele was defined by postoperative computer tomography within 2 weeks after surgery. @*Results@#A total of 116 patients underwent lymphadenectomy, of whom, 47 (42.0%) developed lymphocele and 14 (12.1%) had symptomatic lymphocele formation. The affecting factors of lymphocele formation were PLND concomitant with PALND and a large amount of blood loss ≥600 mL (P=0.030 and P=0.006, respectively). All clinical factors were not significantly different between patients with symptomatic and asymptomatic lymphocele. Lymphocele developed more frequently in the left side (67.1%) of the body compared to the right side (48.7%), and in the pelvic area (75.9%) compared to the para-aortic area (24.1%, P<0.001, both). @*Conclusion@#Lymphocele formation is more prevalent in the left and pelvic area of the body compared to the right and paraaortic side. PLND concurrent with PALND and large amounts of blood loss were significant risk factors for lymphocele formation.
ABSTRACT
Purpose@#This study evaluated the surgical volumes and types of specific surgical procedures in a single trauma center for 3 consecutive years. @*Methods@#From January 2014 to December 2016 there were 9,530 injury cases in the trauma registry that were reviewed. @*Results@#There were 1,502 patients (15.8%) with an injury severity score over 15, of which 426 (28.4%) underwent an emergency operation or had an interventional radiology procedure. There were 186 craniotomies, 87 laparotomies, and 74 interventional radiology procedures performed. @*Conclusion@#The number of emergency operations by each dedicated trauma surgeon was very low therefore implementation of an acute-care surgery model is appropriate to consider together with changes to the training program for trauma surgeons.

ABSTRACT
Absence seizures (AS) are generalized non-convulsive seizures characterized by a brief loss of consciousness and spike-and-wave discharges (SWD) in an electroencephalogram (EEG). A number of animal models have been developed to explain the mechanisms of AS, and thalamo-cortical networks are considered to be involved. However, the cortical foci have not been well described in mouse models of AS. This study aims to use a high density EEG in pathophysiologically different AS models to compare the spatiotemporal patterns of SWDs. We used two AS models: a pharmacologically induced model (gamma-hydroxybutyric acid, GHB model) and a transgenic model (phospholipase beta4 knock-out, PLCβ4 model). The occurrences of SWDs were confirmed by thalamic recordings. The topographical analysis of SWDs showed that the onset and propagation patterns were markedly distinguishable between the two models. In the PLCβ4 model, the foci were located within the somatosensory cortex followed by propagation to the frontal cortex, whereas in the GHB model, a majority of SWDs was initiated in the prefrontal cortex followed by propagation to the posterior cortex. In addition, in the GHB model, foci were also observed in other cortical areas. This observation indicates that different cortical networks are involved in the generation of SWDs across the two models.

Angelica koreana is an important medicinal plant for some locals in East Asia including Korea. A few reports have shown the efficacy of its phytochemical constituents. We have isolated and purified one compound falcarindiol (FAL) from the methanolic extract of A. koreana roots. At concentrations from to 1 µM to 25 µM, the FAL isolated from the roots of A. koreana exerted no significant cytotoxicity and down-regulated LPS-stimulated pro-inflammatory cytokine IL-8 in colon epithelial cells, while up-regulating anti-inflammatory cytokine IL-10. In addition, the FAL decreased the expression of LPS-induced inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 protein by Western blot analysis. Colon epithelial cells play pivotal roles in regulating the colon immune system and thus FAL is expected to be candidate agent as therapeutic potential for the treatment of inflammatory bowel disease (IBD) by modulating LPS-induced inflammation in colon epithelial cells.

Compartment syndrome is a clinical condition associated with decreased blood circulation that can lead to swelling of tissue in limited space. Several factors including lithotomy position, prolonged surgery, intermittent pneumatic compressor, and reperfusion after treatment of arterial thrombosis may contribute to compartment syndrome. However, compartment syndrome rarely occurs after gynecologic surgery. In this case, the patient was diagnosed as compartment syndrome due to reperfusion injury after treatment of arterial thrombosis, which occurred after laparoscopic radical hysterectomy and pelvic lymph node dissection for cervical cancer. Despite its rarity, prevention and identifying the risk factors of complication should be performed perioperatively; furthermore, gynecologist should be aware of the possibility of complications.

OBJECTIVE: To investigate the safety of umbilical cord milking on both the mother and neonate among very preterm deliveries of less than 33 weeks of gestation. METHODS: Pregnant women who were expected to deliver at between 24 0/7 and 32 6/7 weeks of gestation were randomized to either the umbilical cord milking or immediate cord clamping group. Maternal and neonatal data associated with delivery, in addition to neonatal morbidity and mortality data, were collected and analyzed. RESULTS: Of the 66 preterm deliveries included in the study, 34 were randomized into the milking and 32 into the clamping group. Differences between maternal pre- and post-partum hemoglobin levels were 1.35 g/dL in the milking and 1.58 g/dL in the clamping group (P=0.451). Neonatal Apgar scores at both 1 and 5 minutes, initial blood gas analysis results, body temperature at admission, need for early intubation, and maximum bilirubin levels were all similar between the 2 groups. However, neonatal hemoglobin levels at birth (15.79 vs. 14.69 g/dL; P<0.05) and at 24 hours of age (14.83 vs. 13.29 g/dL; P<0.05) were significantly higher in the milking group. Neonates in the clamping group required more blood transfusion (1.78 vs. 0.93; P=0.049), and a higher percentage of neonates in the clamping group required inotropic drugs (63% vs. 29%; P=0.007). The mortality rate was significantly lower in the milking group (6% vs. 28%; P=0.015). CONCLUSION: Umbilical cord milking can be a safe and beneficial procedure for both the mother and the neonate in deliveries of less than 33 weeks of gestation.

Spontaneous resolution of the arterial obstruction in Takayasu's arteritis is rarely reported. We reported a case of spontaneous resolution of an obstruction of the left subclavian artery in a young female. The patient underwent a bilateral coronary patch ostioplasty for both coronary ostial lesions complicated by Takayasu's arteritis at the age of 28. Concomitant left subclavian obstruction was seen at that time but left untreated. Surprisingly, the 10-year follow-up angiogram revealed complete resolution of the left subclavian artery obstruction. Meanwhile, no specific medical treatment was administered.
