Background: As interest in health increases, the number of people engaging in weight training to enhance muscle strength andmuscle mass is on the rise. High-intensity weight training has been reported to induce tooth clenching habits, leading to tooth damage and temporomandibular joint (TMJ) abnormalities. Consequently, it is essential to investigate the impact of weight training accompanied by tooth clenching on oral health and to develop guidelines based on these findings. Methods: The study included male participants aged 25 years and older, comprising 15 non-exercisers and 15 professional fitnesstrainers who have been engaged in weight training for over 5 years. Data were collected using a self-administered questionnaire to gather information on age, exercise experience, total weight lifted in three major weight training exercises (deadlift, bench press, and squat), and teeth clenching habits. Additionally, examinations for tooth cracks and fractures, TMJ noise and pain, maximum mouth opening, occlusal force, and occlusal contact area were conducted. Results: Compared to non-exercisers, professional fitness trainers who have been engaged in weight training for over 5 yearsexhibited a higher prevalence of teeth clenching habits. While there were no significant differences between the two groups in occlusal contact area and the extent of tooth fractures, there were significant differences in occlusal force and the degree of tooth cracks. Furthermore, unlike joint noise and TMJ pain, the maximum mouth opening was significantly reduced in professional fitness trainers compared to non-exercisers. Conclusion Our study suggests that the continuation of high-intensity exercise, which induces teeth clenching habits, may causetooth damage and TMJ disorders.

Pharyngocutaneous fistula (PCF) is a communication created between the pharynx and skin of the neck associated with flap reconstruction or primary closure of a pharyngeal defect. In patients who underwent laryngectomy and pharyngectomy, salivary accumulation in the deep neck space through the pharyngeal dehiscence can cause life-threatening complications, among which is carotid artery blow-out. Broad-spectrum antibiotics, compressive dressing, and artificial nutrition are usually applied first. Many closing methods have been studied, both surgically (direct repair or using flaps) and non-surgically (negative pressure therapy, hyperbaric oxygen therapy, or botulinum toxin injection). The use of a vacuum-assisted closure system placed endoluminally or externally has been recently reported to treat any leaks in the upper gastrointestinal tract. Here, we report a successfully-treated PCF using the endoluminal vacuum-assisted closure system.

Background: Atrial fibrillation (AF) is a well-known, long-term complication of atrial septal defect (ASD) in adults, even after device closure. Left atrial (LA) strain rate applied to the analysis of chamber function has been demon‑ strated to be an important predictor of LA reverse remodeling. This study aimed to determine the changes in cham‑ ber function after device closure of ASD. Methods: This prospective study enrolled adults with secundum ASD undergoing transcatheter device closure from December 2016 to August 2017. We analyzed the clinical characteristics and LA strain rate before and six months after ASD closure. Results: A total of 11 patients were enrolled. The mean age was 42.6 ± 9.9 years, and six (54.5%) were females. There was no significant change of conventional echocardiographic parameters after ASD closure. The mean global LA res‑ ervoir strain rate before ASD closure was 1.17 ± 0.34 and 0.85 ± 0.30 after ASD closure (p = 0.030). The median global LA conduit strain rate was 0.68 (0.42–1.16) and 0.41 (0.16–0.79) before and after ASD closure (p = 0.213), respectively. The mean global LA contractile strain rate at the six-month follow-up showed significant improvement compared with pre-procedural strain rate (0.33 ± 0.65 vs. − 0.43 ± 0.38, p = 0.006). Conclusions LA functional changes occurred during the six-month follow-up, while LA and right atrial (RA) geo‑ metric changes were not significant. LA reverse remodeling was proved by restoration of LA late diastolic contractile function.

This paper describes a community effort to improve earlier versions of the full-text corpus of Genomics & Informatics by semi-automatically detecting and correcting PDF-to-text conversion errors and optical character recognition errors during the first hackathon of Genomics & Informatics Annotation Hackathon (GIAH) event. Extracting text from multi-column biomedical documents such as Genomics & Informatics is known to be notoriously difficult. The hackathon was piloted as part of a coding competition of the ELTEC College of Engineering at Ewha Womans University in order to enable researchers and students to create or annotate their own versions of the Genomics & Informatics corpus, to gain and create knowledge about corpus linguistics, and simultaneously to acquire tangible and transferable skills. The proposed projects during the hackathon harness an internal database containing different versions of the corpus and annotations.

BACKGROUND: Candidemia has increased with an increasing number of people in the high risk group and so has become more important. This study was conducted to investigate the isolation rate of Candida species from candidemia patients and the change in rate of antifungal resistance. METHODS: At a single tertiary care hospital, 1,120 blood cultures positive for Candida species from 1997 to 2016 were investigated according to date of culture, gender, age, and hospital department. RESULTS: During the investigation period, the number of candidemia patients increased from 14 in 1997 to 84 in 2016. The most common organism identified during the two decades was Candida albicans (40.8%), followed by Candida parapsilosis (24.1%), Candida tropicalis (13.2%), and Candida glabrata (12.8%). C. glabrata was relatively common in females (45.5%) compared to males. The age group 40-89 years was more frequently infected than other age groups, and the most frequent isolates according to age group were C. albicans in neonate (66.7%), C. parapsilosis in 1-9-year-olds (41.7%), and C. glabrata in those aged ≥60 years (range; 13.3%–20.0%). According to the visited departments, C. albicans, C. glabrata, and Candida haemulonii were more common in medical departments, while C. parapsilosis was more common in surgical departments. In the antifungal susceptibility test, a rising trend of azole resistance among C. albicans and C. glabrata was observed in recent years. CONCLUSION: In this study, it was confirmed that the isolation rate of Candida species in blood is different by age, gender, and hospital department, and the distribution of isolated Candida species changed over time. The resistance patterns of antifungal agents are also changing, and continuous monitoring and proper selection of antifungal agents are necessary.

Streptococcus bovis bacteremia in humans has been traditionally associated with infective endocarditis, colorectal cancer, and liver cirrhosis. S. bovis strains were previously categorized by biotype, but since the 2000s, they have been reclassified by DNA homology. We report a case of S. gallolyticus subsp. gallolyticus bacteremia, identified by 16S rRNA sequencing, in a patient diagnosed with liver cirrhosis. A 61-yr-old man with a history of liver cirrhosis presented to the hospital with a complaint of fever. Blood culture revealed the presence of gram-positive cocci, and the isolated organism was identified as S. bovis by the MicroScan identification kit (Beckman Coulter, USA), but as Enterococcus saccharolyticus by the Vitek 2 identification kit (bioMérieux, USA). The organism was finally confirmed as S. gallolyticus subsp. gallolyticus by 16S rRNA sequencing.

OBJECTIVE: Black raspberry (Rubus occidentalis) has been known for its anti-inflammatory and anti-oxidant effects and for improving vascular endothelial function in patients at high-risk for cardiovascular disease. We investigated short-term effects of black raspberry on lipid profiles, vascular endothelial function and circulating endothelial progenitor cells in statin naïve participants with metabolic syndrome. METHODS: Patients with metabolic syndrome (n=51) without lipid lowering medications were prospectively randomized into the black raspberry group (n=26, 750 mg/day) and placebo group (n=25) during the 12-week follow-up. Lipid profiles, brachial artery flow-mediated dilatation (baFMD) and inflammatory cytokines such as IL-6, TNF-α, C-reactive protein, adiponectin, sICAM-1, sVCAM-1 were measured at baseline and at 12-week follow-up. Central blood pressure and augmentation index were also measured at baseline and at 12-week follow-up. RESULTS: Decreases from baseline in total cholesterol levels (-22.7±34.3 mg/dL vs. 0.0±34.7mg/dL, p<0.05, respectively) and total cholesterol/HDL ratio (-0.34±0.68 vs. 0.17±0.56, p<0.05, respectively) were significantly greater in the black raspberry group when compared to the placebo group. Decreases from baseline in IL-6 (-0.5±1.4 pg/mL vs. -0.1±1.1 pg/mL, p<0.05, respectively) and TNF-α levels (-5.4±4.5 pg/mL vs. -0.8±4.0 pg/mL, p<0.05, respectively) were significantly greater in the black raspberry group. Increases from the baseline in adiponectin levels (2.9±2.1 µg/mL vs. -0.2±2.5 µg/mL, p<.05) were significant in the black raspberry group. Increases in baFMD at 12-week follow-up were significantly greater in the black raspberry group when compared to the placebo group (2.9±3.6 mm vs. 1.0±3.9 mm, p<0.05, respectively). Radial augmentation indexes were significantly decreased in the black raspberry group when compared to the placebo group (-2±10% vs. 4±13%, p<0.05). CONCLUSION: The use of black raspberry significantly decreased serum total cholesterol levels, inflammatory cytokines, and augmentation index, thereby improving vascular endothelial function in statin naïve participants with metabolic syndrome during the 12-week follow-up.

A total of 1,132 pleural fluid culture results obtained from October 2012 to July 2014 were analyzed to elucidate the microbiological characteristics according to transudative and exudative pleural fluid. The pleural fluid cultures were performed using aerobic and anaerobic blood culture bottles. The blood and pleural fluid for total protein, lactate dehydrogenase, and glucose measurement were submitted to laboratory at the same time with pleural fluid cultures. The rates for culture positivity, anaerobes isolation, and polymicrobials between transudative and exudative pleural fluid were 5.2% vs. 10.4%, 14.8% vs. 7.8%, and 14.8% vs. 10.9%.
