RESUMEN
This study aimed to investigate effects of long-term probiotic supplementation on gut microbiota and growth performance in health weaned piglets. The non-probiotic group (N-PrB) was fed only a basal diet, while the probiotic group (PrB) was fed a basal diet + probiotic combination (E. faecium 1.6 × 108 CFU/g, B. subtilis 2.0 × 108 CFU/g, S. cerevisiae 3.0 × 108 CFU/g). The probiotics combination was provided to the PrB, mixing with the basal diet in 5 kg/ton. As a result, the PrB exhibited significantly improved weight gain compared to the N-PrB (p = 0.00991). In the gut microbiome analysis, the PrB exhibited a significant increasing tendency of α-diversity compared to those of the N-PrB (p < 0.01). In the bacterial relative abundance changes in bacteria comprising the gut microbiota, Ruminococcaceae (p = 0.00281) and Prevotella (p = 0.00687) tended to significantly increase in the PrB, but decreased in the N-PrB. The Eubaterium coprostanoligenes group exhibited an increasing tendency in both groups, but tended to increase more significantly in the PrB compared to the N-PrB (p = 0.00681). Muribaculaceae tended to significantly increase in the N-PrB, but decreased in the PrB (p = 0.002779). In this study, significant differences on the gut microbiome were found according to the probiotics supplementation in the weaned piglets and these gut microbiome changes appeared to improve the growth performance.
RESUMEN
Objectives: To update recent information on contamination levels of mycotoxins in South Korea. Materials and methods: A total of 208 samples sourced from the feeds of swine farms were collected. The contamination levels of mycotoxins, which are aflatoxin (Afla), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), fumonisin (FUM), and T-2 toxin, were investigated by enzyme-linked immunosorbent assays (ELISAs). Results: The detection levels of the total samples were 78.91% for DON, 75.24% for Afla, 47.02% for ZEN, 68.31% for FUM, and 5.94% for OTA and T-2, which were not detected at all. Most of the analyzed mycotoxins showed significant high occurrences in 47.02%-78.91% of the swine feed samples. 11 of the 152 alfa-positive samples exceeded the maximum residue limit (MRL) of Afla proposed by the Korean regulation. In the analysis of mycotoxin detection levels by growth stage, ZEN was found in the nursery stage at a remarkably high concentration level (126.46 ± 63.76 ppb), exceeding the MRL of ZEN for piglets proposed by the European Commission. This mycotoxin was also found in the samples from the gestation barn (89.04 ± 46.05 ppb) and the farrowing house (105.58 ± 94.12) at a high concentration level. Afla was found in the nursery stage at a high concentration (8.00 ± 2.22 ppb), approaching the MRL (10 ppb) of Afla proposed by the Korean regulation. Conclusion: These results indicate that many swine farms in South Korea are still exposed to mycotoxin risk, and special attention and surveillance are necessary for these mycotoxin risks in swine farms.
RESUMEN
With the recent increase in imaging tests, coexisting abdominal aortic aneurysms (AAAs) and thoracic aortic aneurysms (TAAs) are being discovered accidentally. We report two cases of simultaneous endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) for AAA and TAA. Both 74-year-old and 79-year-old male with infrarenal AAA and saccular TAA were treated simultaneously with EVAR and TEVAR. Saccular TAAs were identified in the upper thoracic aorta during the evaluation of AAA. During endograft placement, carotid-subclavian bypass and cerebrospinal fluid (CSF) drainage were performed. Both patients were successfully discharged without spinal cord ischemia. Simultaneous EVAR and TEVAR can be considered for patients with AAA and saccular TAA in the upper thoracic aorta. Moreover, CSF drainage may be necessary to protect the spinal cord.
RESUMEN
BACKGROUND AND PURPOSE: The estimated prevalence of migraines in South Korea is 6.0%, with affected patients having unmet needs. The efficacy, safety, and tolerability of galcanezumab, a humanized monoclonal antibody, for episodic migraine (EM) prevention was evaluated in South Korean patients. METHODS: During the double-blind period of the EVOLVE-2 phase 3 trial, patients with EM were randomized into placebo, 120 mg-galcanezumab, and 240-mg galcanezumab treatment groups. The primary endpoint was the overall mean change from baseline in the number of monthly migraine headache days during the 6-month double-blind period. We conducted a post-hoc analysis of the South Korean cohort in EVOLVE-2. RESULTS: Among 98 South Korean patients in the intent-to-treat population, significant changes from baseline were observed in the number of monthly migraine headache days in the 240-mg galcanezumab group compared with the placebo group (-2.64, p=0.013), in the percentage of patients with ≥50% reduction in the number of monthly migraine headache days (120 mg: odds ratio=2.43, p=0.030; 240 mg: odds ratio=2.60, p=0.019), in the number of monthly migraine headache days with acute medication use (120 mg: -2.22, p=0.006; 240 mg: -2.23, p=0.005), and in the Migraine-Specific Quality-of-Life Role Function-Restrictive (120 mg: 8.34, p=0.040). Numerical improvements from baseline were observed relative to the placebo group in at least one galcanezumab group for: the percentage of patients with ≥75% reduction in the number of monthly migraine headache days functional impairment, and disease severity. The most common treatment-emergent adverse event in the combined galcanezumab group was injection site reaction, which led to treatment discontinuation for one patient. CONCLUSIONS: Galcanezumab treatment demonstrated efficacy and a favorable safety and tolerability profile in South Korean patients with EM.
RESUMEN
BACKGROUND/AIM: Cancer mortality has decreased due to the contribution of extensive research on cancer treatment, including chemotherapy, radiation, and immunotherapy. However, histopathologically similar tumors originating from the same organ are treated with identical or similar chemotherapeutic regimens regardless of patient characteristics or cancer subtypes. The aim of this study was to evaluate the utility of organoids in predicting responses to chemotherapeutic agents. PATIENTS AND METHODS: This study retrospectively reviewed patient-derived organoids (PDOs) from 10 colorectal cancer patients to compare chemotherapy responses. Drug sensitivities for 5-fluorouracil (5-FU), cisplatin, oxaliplatin, and irinotecan were compared using GI50 (concentration that inhibits cancer cell growth by 50%). RESULTS: When organoids were treated with 5-FU, GI50 was the lowest compared to the other three chemotherapeutic agents (cisplatin, oxaliplatin, and irinotecan). The responsiveness to chemotherapeutic agents differed depending on specific patient characteristics including age, tumor location, stage, and gross type. The response of the patients' organoids to chemotherapeutic agents was consistent with the response to chemotherapy actually performed in those patients with cancer recurrence after surgery. CONCLUSION: PDOs may be useful as a preclinical model in predicting chemotherapy responses in cancer patients.

Tumor could directly invade or is adherent to other organs, but superior mesentery vein (SMV) and duodenum invasion are very rare. A 62-year-old woman was diagnosed with abdominal pain for several months. Multiple erythematous brownish skin patches and palpable mass were found at epigastric area. Computed tomography imaging showed focal wall thickening at the transverse colon that invaded to the rectus muscle and anterior abdominal wall. On exploration, we identified tumor invaded or was adherent to the duodenum and superior mesenteric vein and performed en-bloc resection. After surgery, the patient received chemotherapy and was followed up without any recurrence for 16 months. Adhesion and invasion of tumor to surrounding organs can be unexpectedly found during surgery. In our case, we found duodenum and SMV invasion and achieved R0 resection by SMV and duodenum resection, which could improve the patient's prognosis.
RESUMEN
Schwannoma is a benign and uncommon neoplasm arising from the neural crest cells. The most common tumor sites are the skin and subcutaneous tissue of the head and neck. Retroperitoneal schwannomas account for 1-3% of all schwannomas and are predominantly female. In particular, adrenal schwannoma is very rare, and due to its large size at the time of diagnosis, adrenal schwannoma is frequently misdiagnosed as adrenocortical carcinoma or pheochromocytoma. Adrenal schwannoma is difficult to distinguish it from other adrenal diseases based on imaging findings alone. In this report, we introduce the case of a huge left adrenal schwannoma.
RESUMEN
Inguinal hernia repair using prosthetic mesh is used as a standard treatment in most countries and considered superior to primary suture repair. Although prosthetic mesh has greatly reduced the risk of recurrence, the risk of mesh infection remains. A 71-year-old man was diagnosed with symptomatic bilateral inguinal hernias. He underwent successful laparoscopic transabdominal preperitoneal (TAPP) repair and was discharged the same day. After 3 days, he was diagnosed with small bowel perforation, and underwent emergency surgery. We found perforation of the distal ileum caused by the fecal impaction and severe intra-abdominal contamination. We performed subtotal colectomy and ileosigmoid anastomosis, but did not remove the prosthetic mesh because the previous TAPP site was intact. The patient recovered well post-operatively. Therefore, contaminated or dirty surgery immediately after the hernia mesh surgery could be a feasible treatment.
RESUMEN
OBJECTIVE: Effects of direct-fed Enterococcus faecium plus bacteriophages (EF-BP) were investigated as potential substitutes for pharmacological ZnO for weanling pigs. METHODS: Dietary treatments were supplementations to a basal diet with none (NC), 3,000- ppm ZnO (PC), 1×1010 colony-forming units of E. faecium plus 1×108 plaque-forming units (PFU) of anti-Salmonella typhimurium bacteriophages (ST) or 1×106 PFU of each of anti-enterotoxigenic Escherichia coli K88 (F4)-, K99 (F5)-, and F18-type bacteriophages (EC) per kg diet. In Exp 1, twenty-eight 21-day-old crossbred weanling pigs were individually fed one of the experimental diets for 14 days and euthanized for histological examination on intestinal mucosal morphology. In Exp 2, 128 crossbred weanling pigs aged 24 days were group-fed the same experimental diets in 16 pens of 8 piglets on a farm with a high incidence of post-weaning diarrhea. RESULTS: None of the diarrheal score or fecal consistency score (FCS), average daily gain (ADG), gain: feed ratio, structural variables of the intestinal villus, and goblet cell density, differed between the EF-BP (ST+EC) and NC groups, between EF-BP and PC, or between ST and EC, with the exception of greater gain: feed for EF-BP than for PC (p<0.05) during days 7 to 14 (Exp 1). In Exp 2, ADG was less for EF-BP vs PC during days 0 to 7 and greater for EF-BP vs NC during days 7 to 14. FCS peaked on day 7 and declined by day 14. Moreover, FCS was less for EF-BP vs NC, did not differ between EF-BP and PC, and tended to be greater for ST vs EC (p = 0.099). Collectively, EF-BP was comparable to or slightly less effective than PC in alleviating diarrhea and growth check of the weanling pigs, with ST almost as effective as PC, when they were group-fed. CONCLUSION: The E. faecium-bacteriophage recipe, especially E. faecium-anti-S. typhimurium, is promising as a potential substitute for pharmacological ZnO.
RESUMEN
BACKGROUND AND PURPOSE: Several studies have found that the prevalence of migraine is higher among healthcare professionals than in the general population. Furthermore, several investigations have suggested that the personal experiences of neurologists with migraine can influence their perception and treatment of the disease. This study assessed these relationships in Korea. METHODS: A survey was used to investigate the following characteristics among neurologists: 1) the prevalence rates of migraine, primary stabbing headache, and cluster headache, and 2) their perceptions of migraine and the pain severity experienced by patients, diagnosing migraine, evaluation and treatment patterns, and satisfaction and difficulties with treatment. RESULTS: The survey was completed by 442 actively practicing board-certified Korean neurologists. The self-reported lifetime prevalence rates of migraine, migraine with aura, primary stabbing headache, and cluster headache were 49.8%, 12.7%, 26.7%, and 1.4%, respectively. Few of the neurologists used a headache diary or validated scales with their patients, and approximately half were satisfied with the effectiveness of preventive medications. Significant differences were observed between neurologists who had and had not experienced migraine, regarding certain perceptions of migraine, but no differences were found between these groups in the evaluation and preventive treatment of migraine. CONCLUSIONS: The high self-reported lifetime prevalence rates of migraine and other primary headache disorders among Korean neurologists may indicate that these rates are underreported in the general population, although potential population biases must be considered. From the perspective of neurologists, there is an unmet need for the proper application of headache diaries, validated scales, and effective preventive treatments for patients. While the past experiences of neurologists with migraine might not influence how they evaluate or apply preventive treatments to migraine, they may influence certain perceptions of the disease.
RESUMEN
OBJECTIVE: The efficacy of Salmonella typhimurium-specific bacteriophage STP-1 on S. typhimurium infection in weaning piglets was evaluated in this study. MATERIAL AND METHODS: Twenty-eight weaning piglets were randomly allocated to four groups (Group A: non-challenged/basal; Group B: non-challenged/+phage; Group C: challenged/basal; Group D: challenged/+phage) according to S. typhimurium infection or bacteriophage administration. The total experimental period (14 days) was subdivided in to non-challenged periods (phase I; day 1-7) and challenged periods (phase II; day 7-14) based on the challenging date (day 7). Each group was fed with basal feed or feed supplemented with bacteriophage STP-1 [1.0 × 109 plaque-forming unit (PFU)/kg] during the whole period (day 1-14). Body weights (BW) were measured to evaluate growth performance. Clinical symptoms (rectal temperatures and fecal consistency) induced by S. typhimurium were regularly checked. Bacteria colonization levels in feces and intestinal tissue samples were measured using real-time polymerase chain reaction (PCR). After necropsy, small intestine samples (jejunum) were collected. Villus height and crypt depth (CD) were measured through histological examination with H&E staining. RESULTS: The supplementation of bacteriophage significantly reduced bacterial colonization and intestine damage in the piglets infected with S. typhimurium. In the antigen concentrations of the feces and jejunum, Group C showed 5.8 ± 0.6, 5.7 ± 0.6, and 1.2 ± 2.0 log colony-forming unit (CFU)/ml on 1, 3, and 7 days post-inoculation (DPI) and 2.8 ± 1.3 log CFU/ml, whereas Group D showed 3.5 ± 1.7, 2.2 ± 2.1, and 0.3 ± 0.9 log CFU/ml on 1, 3, and 7 DPI and 5.1 ± 0.9 log CFU/ml. In the villous height, Groups C and D showed 266.3 ± 24.1 and 324.6 ± 18.0 µm, respectively. In the goblet cell density of villi and crypts, Group C showed 10.0 ± 1.8 and 16.0 ± 3.7, while Group D showed 15.0 ± 4.8 and 21.1 ± 5.4. Also, the supplementation of bacteriophage significantly improved the growth performance in the infected piglets. The average daily gains of Groups C and D were 91 ± 24 and 143 ± 23, respectively, during the period after inoculation with S. typhimurium. CONCLUSION: The dietary supplementation of the phage was effective for alleviating S. typhimurium infection in post-weaning piglets.
RESUMEN
To evaluate the pulmonary toxicity of Korean chrysotile (KC), 1 or 2 mg of KC (low- and high-concentration groups, respectively) was instilled in the lungs of Sprague-Dawley rats by a single intratracheal instillation. The lungs were examined using a light microscope at several time points (5 days, 5 weeks, and 10 weeks). Up to 10 weeks after KC instillation, differences were observed in the pathological reactions and ultimately in lung recovery between the two groups. At 5 days after KC instillation, lung weight increased and severe bronchiolitis obliterans developed in proportion to the KC concentration administered. From 5 to 10 weeks after KC administration, the lung weight of the low-concentration group increased and bronchiolitis obliterans worsened. In the high-concentration group, the lung weight and the severity of bronchiolitis obliterans at 10 weeks after administration of KC declined compared to those at 5 weeks. In conclusion, the effects of KC on lung tissue were initially found to be more influenced by the amount of fiber, but over time, the effects were influenced by the residual fibrous material in the lung tissue and its biodurability.
RESUMEN
BACKGROUND: To compare the number of lymph nodes (LNs) detected when using Carnoy's solution (CS) versus 10% neutral buffered formalin (NBF) to fix specimens after radical gastrectomy for gastric cancer. PATIENTS AND METHODS: LNs were routinely detected using NBF until 2020, since then, for the fixation procedure, residual fat was fixed in CS for 24 hours and dissected again for the detection of further LNs. Of 143 specimens, 117 were included in the NBF group and 26 in the CS group. RESULTS: The mean numbers of LNs examined were 27.85±14.89 and 36.30±12.41 in the NBF and CS groups, respectively (p=0.008). The mean number of additional LNs detected using CS was 8.07±2.91, of which 0.38±1.02 were metastatic. Additional LNs were found in all patients of the CS group, and all were ≤3 mm. Of the 26 patients in the CS group, metastatic LNs were detected in four, disease in two of whom was up-staged. CONCLUSION: CS is an appropriate alternative to NBF for the fixation of gastric cancer specimens, and more LNs were detected in the resected specimens fixed when using CS compared with NBF.

PURPOSE: Conservative treatment is the first-line therapy for acute colonic diverticulitis without severe complications, but treatment failure may increase hospitalization duration, medical costs, and morbidities. Usage of the modified Hinchey classification is insufficient to predict the outcome of conservative management. We aimed to investigate the clinical efficacy of the modified Hinchey classification and to evaluate predictive factors such as inflammatory markers for the failure of conservative management. METHODS: Patients diagnosed with right colonic diverticulitis undergoing conservative treatment at 3 hospitals between 2017 and 2019 were included. Patients were categorized into conservative treatment success (n = 494) or failure (n = 46) groups. Clinical characteristics and blood inflammatory markers were assessed. RESULTS: The conservative treatment failure group presented with more elderly patients (>50 years, P = 0.002), more recurrent episodes (P < 0.001), a higher lymphocyte count (P = 0.021), higher C-reactive protein (CRP) levels (P = 0.044), and higher modified Glasgow prognostic scores (P = 0.021). Multivariate analysis revealed that age of >50 years (odds ratio [OR], 2.54; 95% confidence interval [CI], 1.27-5.08; P = 0.008), recurrent episodes (OR, 4.78; 95% CI, 2.38-9.61; P < 0.001), and higher CRP levels (OR, 1.08; 95% CI, 1.03-1.12; P = 0.001) were predictive factors for conservative treatment failure, but not the modified Hinchey grade (P = 0.159). CONCLUSION: Age of >50 years, recurrent episodes, and CRP levels are potential predictors for conservative management failure of patients with right-sided colonic diverticulitis. Further studies are warranted to identify candidates requiring early surgical intervention.
RESUMEN
BACKGROUND: Migraine is a neurological, primary headache disorder affecting more than 1 billion people worldwide, with a multi-faceted burden that can significantly impact the everyday life of a patient, both during and between attacks. However, studies on patient awareness, burden, and clinical management of migraine in Korea are limited and outdated. The aim of this study was to comprehensively investigate the current difficulties and unmet needs that Korean patients with migraine encounter from their perspective. METHODS: A total of 207 patients with episodic or chronic migraine aged between 15 and 76 years, completed a survey designed to cover the following topics: diagnosis, understanding of the disease, treatment experience, disability, and quality of life. Patients were recruited by their neurologists from 11 specialized headache clinics in Korea and completed the survey between 22 July and 19 August 2019. Validated scales such as the Migraine Disability Assessment (MIDAS) questionnaire and Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQv2.1) were used to assess levels of disability and quality of life, respectively, in patients. RESULTS: On average, it took 10.1 years from onset of symptoms to diagnosis and a mean of 3.9 hospitals were visited for treatment prior to the patient's current hospital. There was a lack of understanding among respondents about migraine, with 55.6% believing that unilateral headache is a unique feature of migraine compared with other headache disorders. On average, high levels of disability and poor quality of life were reported by patients, as assessed by MIDAS and MSQv2.1, respectively, but only 23.7% had regularly taken preventive medication in the past. Overall satisfaction with previous doctor-patient relationships was reported by 29.5% of respondents, and satisfaction with preventive and acute medications by only 40.8% and 27.1% of the respondents, respectively. CONCLUSION: Korean patients with migraine experience significant disability and reduced quality of life as a result of the disease and have clear unmet needs in terms of diagnosis, understanding of the disease, and disease management including treatment.

Quantitative single-photon emission computed tomography/computed tomography (SPECT/CT) using Tc-99m pertechnetate aids in evaluating salivary gland function. However, gland segmentation and quantitation of gland uptake is challenging. We develop a salivary gland SPECT/CT with automated segmentation using a deep convolutional neural network (CNN). The protocol comprises SPECT/CT at 20 min, sialagogue stimulation, and SPECT at 40 min post-injection of Tc-99m pertechnetate (555 MBq). The 40-min SPECT was reconstructed using the 20-min CT after misregistration correction. Manual salivary gland segmentation for %injected dose (%ID) by human experts proved highly reproducible, but took 15 min per scan. An automatic salivary segmentation method was developed using a modified 3D U-Net for end-to-end learning from the human experts (n = 333). The automatic segmentation performed comparably with human experts in voxel-wise comparison (mean Dice similarity coefficient of 0.81 for parotid and 0.79 for submandibular, respectively) and gland %ID correlation (R2 = 0.93 parotid, R2 = 0.95 submandibular) with an operating time less than 1 min. The algorithm generated results that were comparable to the reference data. In conclusion, with the aid of a CNN, we developed a quantitative salivary gland SPECT/CT protocol feasible for clinical applications. The method saves analysis time and manual effort while reducing patients' radiation exposure.

BACKGROUND: Nobiletin is a natural compound with anticancer activity; however, the mechanism is not clear. METHODS: The inhibitory effect of nobiletin on non-small-cell lung cancer (NSCLC) cells was examined using soft agar, Transwell, and apoptosis analyses. Cancer stemness was measured by sphere assay. Genes and miRNAs regulated by nobiletin were identified by whole-genome sequencing. Protein levels were detected by western blot and immunofluorescence assays. RESULTS: Nobiletin significantly inhibited NSCLC cell colony formation and sphere formation and induced apoptosis. Nobiletin upregulated negative regulators of WNT/ß-catenin signaling, including NKD1, AXIN2, and WIF1, while it inhibited the expression of ß-catenin and its downstream genes, including c-Myc, c-Jun, and cyclin D1. Furthermore, we identified that GN inhibits miR-15-5p expression in NSCLC cells and that NKD1, AXIN2, and WIF1 are the target genes of miR-15-5p. CONCLUSIONS: Nobiletin has a strong inhibitory effect on NSCLC, and nobiletin plays an anticancer role by inhibiting miR-15-5p/ß-catenin signaling in NSCLC.
RESUMEN
Purpose: Laparoscopic posterior retroperitoneal adrenalectomy (LPRA) is a surgical method that accesses the adrenal gland through the back. The aim of this study was to report initial experience of LPRA and evaluate possibilities for surgical application. Methods: From March 2018 to December 2019, a total of 30 consecutive patients diagnosed with adrenal tumor underwent surgical treatment at Pusan National University Hospital were enrolled. Clinicopathologic features and various peri- and postoperative parameters were analyzed by retrospective medical record review. The mean age of the patients was 48.20±13.66 years. Results: The mean body mass index (BMI) was 25.50±4.30 kg/m2. Primary hyperaldosteronism was the most frequently preoperative diagnosed disease (n=13, 43.4%), followed by adrenal incidentaloma (n=8, 26.6%), Cushing syndrome (n=5, 16.6%) and pheochromocytoma (n=4, 13.3%). The mean size of postoperative adrenal tumor was 2.72±1.76 cm. The mean operating time was 162±58.14 minutes. Among the 30 patients, 28 patients underwent total adrenalectomy (93.3%) and two patients underwent cortical sparing adrenalectomy (6.7%). When LPRA was performed for patients with BMI >23.16 kg/m2, the operating time was longer than the average (P=0.016). Conclusion: LPRA was suitable and safe for patients with benign adrenal tumors. BMI, retroperitoneal fat density and postoperative adrenal weight may be related to the operating time, so they should be considered when deciding on a surgical method for adrenalectomy.
