Background: Migraine is a common neurological disorder that affects the quality of life and causes several health problems. Preventive migraine treatment can reduce migraine frequency, headache severity, and health care costs. This study aimed to estimate the utilization of migraine preventive therapy and associated factors in eligible patients. Methods: We studied 534 patients with migraine who were eligible for migraine preventive therapy using 2017 National Patient Sample (NPS) data from the Health Insurance Review and Assessment Service (HIRA). We estimated the migraine days by calculating the monthly average number of defined daily dose (DDD) of migraine-specific acute drug. Patients with a monthly average number of DDD of 4 or more were considered as subjects for preventive treatment. Chi-square test and multiple logistic regression analysis were used to determine the association between the preventive therapy and the influencing variables. Results: Less than half of the eligible patients for prophylaxis (n=234, 43.8%) were prescribed preventive therapy. Multiple logistic regression results show that migraine preventive therapy was influenced by age, the type of migraine, and some comorbidities. Patients over the age of 50 tend to receive less prophylactic treatment than under the age of 40. On the other hand, migraine patients with epilepsy or depression were more likely to receive preventive therapy. Sumatriptan was the most preferred medication for acute treatment, and propranolol was the most commonly prescribed drug for prevention. Conclusions: More than half of the patients who were candidates for migraine prophylaxis were not receiving suitable preventive treatment. Positive factors affecting the use of migraine prevention were the presence of comorbidities such as epilepsy and depression.

A 23-month-old Holstein cattle showed excess salivation and reluctance of walking and suddenly died after forced sudden movements. Grossly, numerous fibrous adhesions were present within cranial abdominal cavity including the reticulum and diaphragm and thoracic cavity involving lungs, pericardial sac, and heart. A perforation made by a 10 cm-long sharp-ended wire was detected in the reticulum. Histopathologically, fibrous suppurative epicarditis and myocardial necrosis were observed. Fibrosis with neovascularization were found in lungs, spleen, and liver. And granulomatous reticulitis was observed. For differential diagnosis, no pathogenic bacteria were detected through microbiological tests and PCR results were also negative for bovine susceptible pathogenic antigens. Based on the gross and histopathological examination, we diagnosed this case as chronic traumatic pericarditis. Cattle are inquisitive and prone to swallow various kinds of metallic foreign bodies since they do not use their lips. Therefore, avoiding ingestion of metallic objects in animal feed and animal areas by careful environmental management of farms is required and farmers should give the adequate minerals and vitamins into the feeds not to lick or shallow foreign bodies in case of mineral deficiency. For veterinary practitioners, physical examination, blood tests, and diagnostic imaging (X-ray and Ultrasonography) are required for an exact diagnosis. Furthermore, placing the magnets in rumen would be effective for prophylactic administrations.

Background and Objectives Tracheostomy lead to persistent bacterial colonization of the respiratory tract. Surgical site infection and restenosis by the pathogenic bacteria is the most fatal complication after open airway surgery. The aim of this study is to describe the culture results of larynx and tracheostoma in patients with tracheostomy and the preoperative, intraoperative culture results in patients underwent open airway surgery. Materials and Method A retrospective review was performed on 18 patients who underwent culture between 2017 and 2019. Results Pseudomonas or antibiotic resistance bacteria were identified in 11 patients out of 18 patients (61.1%); Ceftriaxone-resistant Streptococcus (38.9%), Pseudomonas (33.3%), Methicillin-resistant Staphylococcus aureus (16.7%), extended-spectrum β-lactamases (ESBL) producing Klebsiella pneumoniae (11.1%). Among 18 patients, 6 patients showed the different culture result between larynx and tracheostoma. In 4 out of 10 patients who underwent open airway surgery, the bacteria were not identified before surgery, but the bacteria were isolated in the intraoperative culture. In one patient, the bacteria detected intraoperatively were different from those detected before surgery. Conclusion Preoperative respiratory tract culture and usage of perioperative antibiotics according to the culture are necessary. It is crucial to verify the bacterial culture in both tracheostoma and larynx. And it should be performed immediately before open airway surgery.

Background: Postural control deficit is a major characteristic in patients with chronic ankle instability (CAI). Elastic ankle tapings are commonly used to facilitate postural control in patients with CAI as well as prevent relapse of a lateral ankle sprain. However, equivocal evidence exists concerning the effect of elastic ankle taping on postural control. Objects: This study aimed to evaluate the effects of elastic ankle tapings using kinesio taping (KT) and dynamic taping (DT) on static and dynamic postural control in patients with CAI. Methods: Fifteen subjects with CAI were participated in this study. The participants performed tests under three conditions (barefoot, KT, and DT). Static postural control was evaluated using the one-leg standing test (OLST) and dynamic postural control using the modified Star Excursion Balance Test (mSEBT). One-way repeated-measures analysis of variance was used to compare center of pressure (CoP) data and normalized mSEBT reach distances among the three conditions (with α = 0.05). Results: The CoP parameters (path length, ellipse area, and mean velocity) of the OLST significantly decreased on applying KT and DT compared with those when barefoot. The normalized reach distances in the anteromedial (AM), medial (M), and posteromedial (PM) directions of the mSEBT significantly increased with DT compared to that in the control condition. Further, the higher reach distances with KT compared with those in the control condition were obtained in the M and PM directions of the mSEBT. No significant differences were identified in any of the OLST and SEBT parameters between the two different taping applications. Conclusion: KT and DT improved static postural control during the OLST compared with the control condition. Moreover, these tapes improved dynamic postural control during the mSEBT compared to the control. Therefore, elastic ankle tapings are useful prophylactic devices for the prevention and treatment of ankle sprain in people with CAI.

In this study, in order to evaluate the anti-obesity effect of sargassum horneri extract, the effects of the extract on lipase activity and preadipocyte differentiation in 3T3-L1 cells were investigated. S. horneri extract between 0.0 and 1.0 mg/mL showed no cytotoxicity and inhibited lipase activity by 68.1%. When S. horneri extract was utilized at levels of 0.25, 0.5, and 1.0 mg/mL in 3T3-L1 cells, preadipocytes differentiation decreased by 11.4, 19.7, and 25.6%, respectively, showing anti-obesity effects. In addition, after treatment with 1.0 mg/mL S. horneri extract, the mRNA expression levels of sterol regulatory element binding proteins-1c (SREBP-1c), peroxisome proliferator activated receptor-γ (PPAR-γ), CCAAT enhancer binding protein-α (CEBP-α), fatty acid synthase (FAS), and stearoyl-CoA desaturase1 (SCD1) in 3T3-L1 cells were significantly decreased (p < 0.05) by 65.2, 54.9, 50.0, 33.8, and 33.8% respectively. These results showed that S. horneri extract suppresses lipase activity and prophylactic preadipocyte differentiation in 3T3-L1, and thus can be used as an anti-obesity agent in functional foods and medicines.

Background: Nonalcoholic steatohepatitis (NASH) is one of the main chronic liver diseases. NASH is identified by lipid accumulation, inflammation, and fibrosis. Jinan Red Ginseng (JRG) and licorice have been widely used because of their anti-inflammatory and hepatoprotective effects. Hence, this study assessed JRG and licorice extract mixtures' effects on NASH progression. Methods: Palmitic acid (PA) and the western diet (WD) plus, high glucose-fructose water were used to induce in vitro and in vivo NASH. Mice were orally administered with JRG-single (JRG-S) and JRG-mixtures (JRG-M; JRG-S + licorice) at 0, 50, 100, 200 or 400 mg/kg/day once a day during the last half-period of diet feeding. Results: JRG-S and JRG-M reduced NASH-related pathologies in WD-fed mice. JRG-S and JRG-M consistently decreased the mRNA level of genes related with inflammation, fibrosis, and lipid metabolism. The treatment of JRG-S and JRG-M also diminished the SREBP-1c protein levels and the p-AMPK/AMPK ratio. The FAS protein levels were decreased by JRG-M treatment both in vivo and in vitro but not JRG-S. Conclusion: JRG-M effectively reduced lipogenesis by modulating AMPK downstream signaling. Our findings suggest that this mixture can be used as a prophylactic or therapeutic alternative for the remedy of NASH.

Background: Prophylactic antibiotics are used to prevent surgical wound infection; however, proper indications must be followed with careful consideration of the risks and benefits, especially in clean or clean-contaminated wounds. Nasal bone fractures are the most common type of facial bone fracture. The most common method for treating nasal bone fracture is closed reduction, which is performed inside the nasal cavity without an incision. The purpose of this study was to determine the need for antibiotic use in the closed reduction of nasal bone fractures. Methods: A retrospective study was conducted using data from the National Insurance Service Ilsan Hospital of the Republic of Korea between 2016 and 2018. The records of patients who underwent closed reduction of nasal bone fracture were reviewed and classified according to sex, age, comorbidities, perioperative antibiotic usage, postoperative complications, nasal packing, anesthesia type, surgeon's specialty, and operation time. Results: Among the 373 patients studied, the antibiotic prescription rate was 67.3%. Just 0.8% of patients were prescribed preoperative antibiotics only, 44.0% were prescribed postoperative antibiotics only, and 22.5% were prescribed both preoperative and postoperative antibiotics. There were no cases that satisfied the definition of "surgical site infection." Furthermore, 2.1% of infection-related complications (e.g., mucosal swelling, synechia, and anosmia) occurred only in the antibiotic usage group. The use of nasal packing, anesthesia type, and surgeon's specialty did not show any difference in infection-related complication rates. Conclusion: According to the study findings, the routine use of perioperative antibiotics is not recommended in uncomplicated nasal bone fracture surgery.

Single-cycle viruses generated by reverse genetic technology are replication-incompetent viruses due to the elimination of gene(s) essential for viral replication, which provides a way to overcome the safety problem in attenuated viruses. Infectious hematopoietic necrosis virus (IHNV) is a major pathogen causing severe damage in cultured salmonid species. In the present study, we generated a single-cycle IHNV lacking the transmembrane and cytoplasmic domain in the G gene (rIHNV-GΔTM) and evaluated the prophylactic potential of rIHNV-GΔTM in rainbow trout (Oncorhynchus mykiss). To produce rIHNV-GΔTM, IHNV G protein-expressing Epithelioma papulosum cyprini (EPC) cells were established. However, as the efficiency of rIHNV-GΔTM production in EPC cell clones was not high, fish were immunized with a low-tittered single-cycle virus (1.5 × 10² PFU/fish). Despite the low dose, the single-cycle IHNV induced significant protection in rainbow trout against IHNV infection, suggesting high immunogenicity of rIHNV-GΔTM. No significant difference in serum ELISA titers against IHNV between the rIHNV-GΔTM immunized group and the control group suggests that the immunized dose of rIHNV-GΔTM might be too low to induce significant humoral adaptive immune responses in rainbow trout. The involvement of adaptive cellular immunity or innate immunity in the present significantly higher protection by the immunization with rIHNV-GΔTM should be further investigated to know the protection mechanism.

Objectives : The purpose of this study was to determine whether the methanol extract of Cassia mimosoides var. nomame Makino, a naturally growing plant in Korea, could prevent the renal-ischemia/reperfusion injury in a rat model or not. Methods : The radical scavenging activities of the extracts, and ascorbic acid as a positive control, were measured in vitro. At one hour after an intraperitoneal injection of the extract (400 mg/kg), renal ischemia/reperfusion injury was generated by 40 min clamping of the left renal artery in rats. After renal ischemia/reperfusion and 24 hr restoration of blood circulation, the serum creatinine concentration was measured. And the extent of epithelial cell injury and apoptosis was assessed by various staining technologies. The Bax/Bcl-2 ratio and activated caspase-3 were assessed by immunohistochemistry. Results : The extract showed a slightly lower level of radical scavenging activity than that of ascorbic acid. Compared to those of the vehicle-treated group, the extract-treated group displayed a significantly smaller tubular epithelial cell injury of 54% reduction in the outer medulla region and a lower serum creatinine concentration of 50% reduction. It seems that the reduction in cellular injury is due to the attenuation of the Bax/Bcl-2 ratio, and the inhibition of caspase-3 activation by the extract of Cassia mimosoides. Conclusions : Cassia mimosoides var. nomame Makino could be a good candidate for a prophylactic agent against the ischemia/reperfusion/induced kidney injury.

Background: The PyeongChang 2018 Winter Paralympic Games (WPG) being one of the most successful Paralympic Games (PG) in modern athletic world history, hosted the largest number of elite athletes representing 49 National Paralympic Committees (NPCs). Objects: The present investigation highlighted the demographic and clinical characteristics of injured athletes and non-athletes and the physiotherapy services provided during the PyeongChang 2018 WPG. Methods: Prospective descriptive epidemiology study, in which the study group comprised of 201 participants (51 athletes and 150 non-athletes) who were admitted to and utilized the polyclinic physiotherapy service of 2018 PyeongChang WPG in Physiotherapy Department of Paralympic Village from March 1, 2018 to March 20, 2018. Results: Qualitative frequency analysis of injury type demonstrated highest number of chronic injuries (51%, n = 100) in athletes and non-athletes. Anatomical injury site analysis revealed that the spine and shoulder areas were affected with equal frequency for athletes (54.9%, n = 14), whereas for non-athletes, the frequencies of spine and shoulder area injuries were 36.7% (n = 55) and 26% (n = 39), respectively. The Pyeongchang WPG showed a high rate of athletes visiting the physiotherapy service during the pre-competition period (33.3%, n = 50), which may have led to smaller incidence rate of traumatic injury. The physiotherapy treatment service analysis demonstrated that manual therapy (35.4%, n = 230) was most commonly utilized, followed by transcutaneous electrical nerve stimulation/interference current therapy (TENS/ICT), therapeutic massage and therapeutic exercise. Conclusion: We established the importance of prophylactic and preventive physiotherapy services to reduce the risk of sports injuries during WPG.
