ABSTRACT

BACKGROUND@#To achieve optimal bone marrow engraftment during bone marrow transplantation, migration of donor bone marrow cells (BMCs) toward the recipient’s bone marrow is critical. Despite the enhanced engraftment of BMCs by co-administration of mesenchymal stem cells (MSCs), the efficiency can be variable depending on MSC donor. The purpose of this study is to examine the functional heterogeneity of tonsil-derived MSCs (TMSCs) and to identify a marker to evaluate efficacy for the enhancement of BMC migration. @*METHODS@#To examine the donor-to-donor variation of TMSCs in potentiating BMC migration, we isolated TMSCs from 25 independent donors. Transcriptome of TMSCs and proteome of conditioned medium derived from TMSC were analyzed. @*RESULTS@#Enhanced BMC migration by conditioned medium derived from TMSCs was variable depending on TMSC donor. The TMSCs derived from 25 donors showed distinct expression profiles compared with other cells, including fibroblasts, adipose-derived MSCs and bone marrow–derived MSCs. TMSCs were distributed in two categories: high- and low-efficacy groups for potentiating BMC migration. Transcriptome analysis of TMSCs and proteome profiles of conditioned medium derived from TMSCs revealed higher expression and secretion of matrix metalloproteinase (MMP) 1 in the high-efficacy group. MMP1 knockdown in TMSCs abrogated the supportive efficacy of conditioned medium derived from TMSC cultures in BMC migration. @*CONCLUSION@#These data suggest that secreted MMP1 can be used as a marker to evaluate the efficacy of TMSCs in enhancing BMC migration. Furthermore, the strategy of analyzing transcriptomes and proteomes of the MSCs may be useful to set the standard for donor variation.

ABSTRACT

Background@#Various treatments exist for addressing volume loss in atrophic scars. Although laser therapy has gained traction in treating atrophic scars, it is associated with side effects, such as post-inflammatory hyperpigmentation or erythema. Additionally, not all types of atrophic scars respond optimally to laser therapy, even after multiple sessions. @*Objective@#This study aimed to evaluate the efficacy and safety of punch elevation for atrophic scars that yielded unsatisfactory outcomes after repeated laser treatment sessions. @*Methods@#Seven patients with atrophic scars on their facial area underwent punch elevation, concurrently supplemented by fractional CO2 laser application to the scar margins. Improvement in volume restoration of atrophic scars was assessed via investigator evaluation and 3-dimensional (3D) image analysis. @*Results@#After 1 month, median volume (interquartile range) of depression improved from 4.39 mm3 (2.23∼9.90 mm3 ) to 1.97 mm3 (1.46∼7.50 mm3 ), indicating a statistically significant difference post-punch elevation (p=0.018). No serious adverse events were reported during follow-up. @*Conclusion@#The efficacy of the punch elevation was objectively evaluated. Punch elevation is a safe and effective therapeutic avenue for atrophic scars that exhibit resistance to laser or alternative interventions.

ABSTRACT

Background@#In patients with early-stage breast cancer, the treatment results of hypofractionated radiation therapy (RT) and conventional RT are evaluated in efficacy and cost. @*Methods@#We retrospectively evaluated 280 patients with early-stage (Tis-2N0M0) breast cancer (including 100 hypofractionated RT patients) with regards to treatment outcomes according to the RT schedule. The median whole-breast RT dose was 42.56 Gy/16 fractions for hypofractionated RT and 50.4 Gy/28 fractions for conventional RT. Most patients (n = 260, 92.9%) additionally received a tumor bed boost RT. We used propensity score matching (PSM) analysis to balance the baseline risk factors for recurrence. The co-primary endpoints of this study were disease-free survival (DFS) and ipsilateral breast tumor recurrence (IBTR).DFS or IBTR was analyzed using the Kaplan-Meier survival curve and log-rank test. @*Results@#Total 89 pairs of matched patients (1:1 matching, n = 178) were finally evaluated.The median follow-up was 23.6 months. After matching, the 3-year DFS was 100% in the hypofractionated RT group and 98.4% in the conventional RT group; there was no significant difference in DFS between the groups (P = 0.374). Furthermore, the IBTR did not differ between the hypofractionated RT and conventional RT groups (P = 0.374) after matching. The 3-year overall survival was not different between two groups (both 100%). Hypofractionated RT saved 26.6% of the total cost of RT compared to conventional RT. Additionally, the acute skin toxicity rate (≥ grade 2) was also not significantly different between the groups (hypofractionated RT: 10.1% vs. conventional RT: 2.2%). @*Conclusion@#Hypofractionated RT showed good IBTR and DFS, which were compatible to those in conventional RT in breast cancer. Hypofractionated RT is expected to be used more widely because of its low cost and convenience.

ABSTRACT

Background/Aims@#L-carnitine is potentially beneficial in patients with hepatic encephalopathy (HE). We aimed to evaluate the impact of L-carnitine on the quality of life and liver function in patients with liver cirrhosis and covert HE. @*Methods@#We conducted an investigator-initiated, prospective, multi-center, double- blind, randomized phase III trial in patients with covert HE. A total of 150 patients were randomized 1:1 to L-carnitine (2 g/day) or placebo for 24 weeks. Changes in quality of life and liver function were assessed at 6 months. The model for end-stage liver disease (MELD), the 36-Item Short Form Survey (SF-36), the psychometric hepatic encephalopathy score (PHES), and the Stroop Test were evaluated in all patients. @*Results@#The total SF-36 score significantly improved in the L-carnitine group after 24 weeks (difference: median, 2; interquartile range, 0 to 11; p < 0.001); however, these values were comparable between the two groups. Furthermore, there was a significant ordinal improvement in PHES scores among patients with minimal HE who were in the L-carnitine group (p = 0.007). Changes in the total carnitine level also positively correlated with improvements in the Stroop test in the L-carnitine group (color test, r = 0.3; word test, r = 0.4; inhibition test, r = 0.5; inhibition/switching test, r = 0.3; all p < 0.05). Nevertheless, the MELD scores at week 24 did not differ between the groups. @*Conclusions@#Twenty-four weeks of L-carnitine supplementation was safe but ineffective in improving quality of life and liver function.

ABSTRACT

BACKGROUND@#The advantages of tonsil-derived mesenchymal stem cells (TMSCs) over other mesenchymal stem cells (MSCs) include higher proliferation rates, various differentiation potentials, efficient immune-modulating capacity, and ease of obtainment. Specifically, TMSCs have been shown to differentiate into the endodermal lineage. Estrogen deficiency is a major cause of postmenopausal osteoporosis and is associated with higher incidences of ischemic heart disease and cerebrovascular attacks during the postmenopausal period. Therefore, stem cell-derived, estrogen-secreting cells might be used for estrogen deficiency. @*METHODS@#Here, we developed a novel method that utilizes retinoic acid, insulin-like growth factor-1, basic fibroblast growth factor, and dexamethasone to evaluate the differentiating potential of TMSCs into estrogen-secreting cells. The efficacy of the novel differentiating method for generation of estrogen-secreting cells was also evaluated with bone marrow- and adipose tissue-derived MSCs. @*RESULTS@#Incubating TMSCs in differentiating media induced the gene expression of cytochrome P450 19A1 (CYP19A1), which plays a key role in estrogen biosynthesis, and increased 17b-estradiol secretion upon testosterone addition. Furthermore, CYP11A1, CYP17A1, and 3b-hydroxysteroid dehydrogenase type-1 gene expression levels were significantly increased in TMSCs. In bone marrow-derived and adipose tissue-derived MSCs, this differentiation method also induced the gene expression of CYP19A1, but not CYP17A1, suggesting TMSCs are a superior source for estrogen secretion. @*CONCLUSION@#These results imply that TMSCs can differentiate into functional estrogen-secreting cells, thus providing a novel, alternative cell therapy for estrogen deficiency.

ABSTRACT

Background/Aims@#This study was performed to evaluate the efficacy of direct-acting antivirals (DAAs) in Korean patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) and to investigate the risk factors associated with HCC recurrence. @*Methods@#A total of 100 patients with HCV-related HCC, who were treated with DAAs between May 2015 and December 2016, were recruited from seven university hospitals in Korea. Claim data of 526 patients with HCC obtained from the Health Insurance Review and Assessment Service in South Korea were used for external validation of the results. @*Results@#Among the 100 patients, 88% achieved a sustained virological response (SVR) 12weeks after the end of DAA therapy (SVR12), and 37% experienced HCC recurrence after DAA therapy. Short last HCC treatment durability (<12 months) before DAA commencement was independently associated with HCC recurrence (hazard ratio [HR], 2.89; p=0.011). In the nationwide validation cohort, 20.3% of the patients experienced HCC recurrence. The last HCC treatment with a noncurative method, a short last HCC treatment durability (<12 months), and a longer total duration of HCC treatment (≥18 months) were independently related with HCC recurrence (HR3.73, p<0.001; HR 3.34, p<0.001; and HR 1.74, p=0.006; respectively). @*Conclusions@#DAA therapy showed an acceptable SVR12 rate in patients with HCV-related HCC. Short last HCC treatment durability (<12 months) was associated with HCC recurrence after DAA therapy. This finding suggests that the last HCC treatment durability is an important predictor of HCC recurrence after DAA therapy.

ABSTRACT

Transcatheter arterial chemoembolization (TACE) is a useful palliative therapeutic modality for hepatocellular carcinoma (HCC). Postembolization syndromes, such as fever, abdominal pain, and elevated liver enzyme levels are commonly known complications of TACE. One post-TACE pulmonary complication, lipiodol pneumonitis, is rarely reported. Lipiodol pneumonitis after TACE appears to be associated with chemical injury due to accidental perfusion of lipiodol to the lung vasculature, promoted by arteriovenous shunts within the hypervascular HCC. Here, we report a 42-year-old man with unresectable HCC and hepatic vein thrombosis. The patient was initially treated with TACE. The following day after TACE, acute respiratory symptoms such as dyspnea and cough developed with decreased oxygen saturation. Chest X-ray and computed tomography showed multiple patches and diffuse ground-glass opacities in both lung fields, suggesting of lipiodol pneumonitis. The patient’s condition and radiologic abnormalities subsequently improved after 2 weeks of conservative treatment alone.

ABSTRACT

Background/Aims@#This study examined the risk factors associated with mortality in cirrhotic patients hospitalized with variceal bleeding, and evaluated the effects of acute-on-chronic liver failure (ACLF) on the prognosis of these patients. @*Methods@#This study was retrospectively conducted on patients registered in the Korean acute-on-chronic liver failure study cohort, and on 474 consecutive cirrhotic patients hospitalized with variceal bleeding from January 2013 to December 2013 at 21 university hospitals. ACLF was defined as described by the European Association for the Study of Liver-Chronic Liver Failure Consortium. @*Results@#Among a total of 474 patients, 61 patients were diagnosed with ACLF. The cumulative overall survival (OS) rate was lower in the patients with ACLF than in those without (P<0.001), and patients with higher ACLF grades had a lower OS rate (P<0.001). The chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score was identified as a significant prognostic factor in patients hospitalized with variceal bleeding (hazard ratio [HR], 1.40; 95% confidence interval [CI], 1.30–1.50; P<0.001), even in ACLF patients with variceal bleeding (HR, 1.32; 95% CI, 1.19–1.46, P<0.001). Concerning the prediction of the mortality risk at 28- and 90-day using CLIF-SOFA scores, c-statistics were 0.895 (95% CI, 0.829–0.962) and 0.897 (95% CI, 0.842–0.951), respectively, and the optimal cut-off values were 6.5 and 6.5, respectively. @*Conclusions@#In cirrhotic patients hospitalized with variceal bleeding, the prognosis was poor when accompanied by ACLF, especially depending upon CLIF-SOFA score. CLIF-SOFA model well predicted the 28-day or 90-day mortality for cirrhotic patients who experienced variceal bleeding.

ABSTRACT

The prevalence of epilepsy and psychosis in 22q11.2 deletion syndrome (22q11.2DS) is higher than in the general population. Recent study on adults with 22q11.2DS reported that the most common trigger for provoked seizures was the use of antipsychotics and antidepressants. In this paper, blonaserin was used because aripiprazole, quetiapine, paliperidone were not effective. The patient had convulsion on the fourth day of taking blonaserin. Neurological and cardiac examination was carried out, and lamotrigine was added at the advice of neurologist. Than the patient didn’t have any convulsions and the symptoms gradually improved. When treating patients with 22q11.2DS, the medicine should be chosen carefully, and the patient should be observed closely, paying attention to the possibility of convulsions.

ABSTRACT

PURPOSE: The role of the host immunologic environment is crucial in cancer progression. Recent studies revealed that neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR), are possible surrogate markers of outcome in various cancers. In breast cancer, the therapeutic effect of neoadjuvant chemotherapy (NAC) differs in patients, and higher response rate reflects better outcomes. This study aimed to determine the predictive value of peripheral blood NLR and PLR for NAC response along with their prognostic role in breast cancer. METHOD: A total of 105 patients with breast cancer treated with NAC between 2009 and 2017 were analyzed retrospectively. NAC response and prognosis (disease-free-survival [DFS], progression-free-survival [PFS] and overall survival [OS]) according to NLR and PLR were evaluated. According to the optimal cut-off values for NAC response obtained from receiver operating characteristic (ROC) curves, patients satisfying both low NLR and PLR levels (low-ratio group) were compared to those who did not (high-ratio group). RESULTS: The NLR cut-off value was ≤ 2.21 (area under the ROC curve [AUC], 0.617; 95% confidence interval [CI], 0.517–0.710; p=0.030) with 94.1% sensitivity and 38.0% specificity. The PLR cut-off value was ≤ 143.36 (AUC, 0.618; 95% CI, 0.518–0.711; p = 0.040) with 85.3% sensitivity and 39.4% specificity. The low-ratio group demonstrated a better NAC response (p = 0.006) in multivariate analysis than the high-ratio group. The low-ratio group showed better DFS and PFS (p = 0.046 and p = 0.040, respectively) and longer OS (p = 0.078) in univariate survival analysis than the high-ratio group. In multivariate analysis, the low-ratio group had significantly better PFS (p = 0.049) and higher DFS (p = 0.054) than the high-ratio group. CONCLUSIONS: The combination of NLR and PLR showed improved prediction of NAC response, revealing their potential as screening tools, significant prognostic role in breast cancer patients who receive NAC. Further studies with subgroup analysis, larger population and longer follow up duration are required.

ABSTRACT

PURPOSE: This study estimated the incidence of delirium and associated risk factors and outcomes in ICU patients with acute poisoning. METHODS: Data were collected from ICU patients over 18 years of age that were admitted via the emergency center after presenting with poisoning from 2010 to 2015. Delirium was assessed retrospectively using the Intensive Care Delirium Screening Checklist (ICDSC). Risk factors were evaluated by univariate and multivariate analysis. RESULTS: A total of 199 patients participated in this study and 68 (34.2%) were diagnosed with delirium based on the ICDSC score. The delirium group showed a significantly higher association with prolonged length of stay in the hospital and ICU in comparison with the non-delirium group. The delirium group was associated with greater use of physical restraint. A statistically greater number of patients with pharmaceutical substance poisoning developed delirium over a short period of time than those with non-pharmaceutical substance poisoning. There was no significant difference between the two groups with respect to age, sex, past history, GCS score, vital signs, application of ventilator care and renal replacement therapy. CONCLUSION: The finding that the delirium group had a greater length of stay in both the hospital and the ICU is consistent with the results of previous worldwide studies of the effects of delirium on the prognosis of patients who were admitted to the ICU, suggesting the possibility for domestic application. Additionally, use of physical restraint was positively related to the incidence of delirium. Thus, interventions for minimizing the use of physical restraints and considering alternatives are needed.

ABSTRACT

BACKGROUND/AIMS@#Entecavir (ETV) is effective and safe antiviral agent against hepatitis B virus (HBV) in clinical and real-world setting but, most studies were performed in single institute or have limitation in patient's number. A large-scale nation-wide real-world surveillance study was carried out to investigate safety, efficacy and clinical effectiveness of ETV in Korean patients with chronic hepatitis B (CHB).@*METHODS@#Between 2006 and 2012, 3,444 patients were enrolled from 132 Korean institutions. For the safety assessment, investigators recorded the occurrence of observed and patient-reported adverse events (AEs), as well as laboratory abnormalities. Efficacy, which consisted of change in HBV DNA and alanine aminotransferase (ALT), was evaluated in patients who had received at least 16 weeks of ETV treatment. Overall clinical effectiveness, based on improvement of ALT, HBV DNA and patient's symptoms, was evaluated by physicians.@*RESULTS@#Of the patients, 3,367 were evaluated for safety and 3,115 for efficacy and clinical effectiveness. Three hundred and eighty AEs were reported in 255 cases (7.57%), and 67 adverse drug reactions in 54 cases (1.6%). Serious AEs (SAE) were 19 events in nine cases (0.27%). Serious adverse drug reactions (SADR) were three events in two cases (0.06%), and unexpected SAE/SADR were three events in two cases (0.06%). Medical history and concomitant medications were factors inf luencing incidence rates of AEs. Overall clinical effectiveness rate was 96.53%, which was clinically assessed as marked improved or improved state.@*CONCLUSIONS@#This study showed that ETV was well tolerated and clinically effective in Korean patients with CHB in a real-world nation-wide setting.

ABSTRACT

Although surgical resection is a curative treatment option for solitary hepatocellular carcinoma, high recurrence rate contributes to dismal long-term prognosis after curative resection. Early recurrence within 2 years after surgery is associated with intrahepatic metastasis of primary tumor. Liver regeneration after hepatic resection can accelerate tumorigenesis in remnant liver. Treatment strategies for intrahepatic recurrence after curative resection include salvage transplantation, repeated resection, local ablation, and transarterial chemoembolization (TACE). Here, we report a 51-year-old male who was presented with a single large tumor located at segment 4. The patient was initially treated with surgical resection, but intrahepatic recurrence occurred only 4 months after surgery. He achieved complete remission with repeated TACE and has survived without recurrence for 4 years so far.

ABSTRACT

BACKGROUND/AIMS: There have been numerous efforts to reduce mother-to-child transmission (MTCT) of hepatitis B virus (HBV) with antiviral agents during pregnancy. However, there are limited data regarding the outcomes of pregnant women after delivery. This study was performed to evaluate the efficacy of antiviral agents in preventing MTCT of HBV and maternal long-term outcomes. METHODS: The HBV-infected pregnant women treated with antiviral agents to prevent MTCT were retrospectively reviewed. Forty-one pregnant women who received telbivudine or tenofovir during late pregnancy (28-34 week) were analyzed. Hepatitis B virus surface antibody (HBsAb) positivity was tested in 43 infants after 7 months of birth. Eleven mothers were followed >1 year after delivery. RESULTS: The mean HBV DNA titer before antiviral therapy was 8.67 (6.60–9.49) log copies/mL, and the median age at delivery was 32 years (range, 22–40). Eleven patients were treated with tenofovir and 30 with telbivudine. The median duration was 57 days (range, 23–100), and the median HBV DNA titer at birth was 5.06 log copies/mL (range, 2.06–6.50). Antiviral treatments were associated with significant HBV DNA reduction (P 12 months, and an antiviral agent was administered. CONCLUSIONS: Antiviral treatment during late pregnancy effectively reduced MTCT. Long-term follow-up should be required in such cases. In addition, given that maternal biochemical flare occurred in 18% of mothers, re-administration of antiviral agents might be required.

ABSTRACT

BACKGROUND/AIMS: An association between reduced pulmonary function and diabetes has been observed. Our aim was to evaluate the prevalence and risk factors associated with reduced pulmonary function in diabetic patients. METHODS: We analyzed data from the Korea National Health and Nutrition Examination Survey 2011 to 2013. The study population included data from 8,784 participants (including 1,431 diabetics) aged ≥ 40 years. Reduced pulmonary function was defined as patients with restrictive (forced expiratory volume in 1 second/forced vital capacity [FEV₁/FVC] ≥ 0.7 and FVC < 80% of predicted value) or obstructive (FEV₁/FVC < 0.7) patterns. RESULTS: Subjects with diabetes had a higher prevalence of restrictive (18.4% vs. 9.4%, p < 0.001) and obstructive impairments (20% vs. 12.6%, p < 0.001) than those without diabetes. The adjusted odds ratios (aORs) (95% confidence interval [CI]) for obstructive and restrictive pulmonary impairment were 0.91 (0.75 to 1.11) and 1.57 (1.30 to 1.89), respectively. In the diabetes population, age (aOR, 1.04; 95% CI, 1.02 to 1.06), male sex (aOR, 1.40; 95% CI, 1.04 to 1.88), and body mass index (aOR, 1.15; 95% CI, 1.10 to 1.21) were independently associated with restrictive pulmonary impairment. Age (aOR, 1.12; 95% CI, 1.09 to 1.14), male sex (aOR, 4.24; 95% CI, 2.42 to 7.44), and smoking at any point (ever-smoker: aOR, 1.96; 95% CI, 1.16 to 3.33) were independent risk factors for obstructive pulmonary impairment in diabetics. Diabetes duration or glycated hemoglobin had no association with pulmonary impairment in diabetes. CONCLUSIONS: Subjects with diabetes had a higher risk of restrictive pulmonary impairment than those without diabetes after adjusting for confounding factors. Older age, male sex, body mass index, and smoking were associated with reduced lung function in diabetes.

ABSTRACT

Hepatogastric fistula following a pyogenic liver abscess is extremely rare, and only a handful of cases have been reported. An 88-year-old female presented with generalized weakness, fever and chills. An abdominal computed tomography scan revealed a 5cm-sized hypodense lesion with internal septa in the left lateral section of the liver. Due to initial suspicion of early liver abscess, she was treated with empirical intravenous antibiotics. Initially, aspiration or drainage of the liver abscess was not performed due to immature lesion characteristics. An ultrasonography-guided percutaneous drainage of the liver abscess was performed 17 days after hospitalization due to a more mature lesion appearance on follow-up imaging.
