ABSTRACT

Alzheimer’s disease (AD) is the most common cause of neurodegeneration. It is characterized by deposits of amyloid beta (Aβ) plaques and impaired memory. Microglia are associated with AD. They are activated in the AD brain and AD models. However, the exact role of microglia has not been established. We thus investigated the role of microglia in AD models using a primary culture and an ex-vivo assay. We showed that oligomerized Aβ is toxic to neurons in the primary culture. In the ex-vivo assay, a microglial cell line removed amyloid plaques in the brain of 5XFAD (AD model) mice. To verify if microglia can be protective for the neuron, we co-cultured neurons with primary microglia and treated them with Aβ. The loss of neurons, induced by amyloid toxicity, was attenuated by co-cultured microglia. Taken together, our data suggest that microglia promote neuronal survival by phagocytic clearance of Aβ in AD models.

ABSTRACT

The Committee of Clinical Practice Guidelines of the Korean Diabetes Association (KDA) updated the previous clinical practice guidelines for Korean adults with diabetes and prediabetes and published the seventh edition in May 2021. We performed a comprehensive systematic review of recent clinical trials and evidence that could be applicable in real-world practice and suitable for the Korean population. The guideline is provided for all healthcare providers including physicians, diabetes experts, and certified diabetes educators across the country who manage patients with diabetes or the individuals at the risk of developing diabetes mellitus. The recommendations for screening diabetes and glucose-lowering agents have been revised and updated. New sections for continuous glucose monitoring, insulin pump use, and non-alcoholic fatty liver disease in patients with diabetes mellitus have been added. The KDA recommends active vaccination for coronavirus disease 2019 in patients with diabetes during the pandemic. An abridgement that contains practical information for patient education and systematic management in the clinic was published separately.

ABSTRACT

In this study, we aimed to investigate the effects of 8 weeks of treatment with a combination of evogliptin and leucine, a branchedchain amino acid, in mice with high-fat diet (HFD)-induced diabetes. Treatment with evogliptin alone or in combination with leucine reduced the body weight of the mice, compared to the case for those from the HFD control group. Long-term treatment with evogliptin alone or in combination with leucine resulted in a significant reduction in glucose intolerance; however, leucine alone did not affect postprandial glucose control, compared to the case for the mice from the HFD control group. Furthermore, the combination of evogliptin and leucine prevented HFD-induced insulin resistance, which was associated with improved homeostasis model assessment for insulin resistance, accompanied by markedly reduced liver fat deposition, hepatic triglyceride content, and plasma alanine aminotransferase levels. The combination of evogliptin and leucine increased the gene expression levels of hepatic peroxisome proliferator-activated receptor alpha, whereas those of the sterol regulatory element-binding protein 1 and stearoyl-CoA desaturase 1 were not altered, compared to the case in the HFD-fed mice (p<0.05). Thus, our results suggest that the combination of evogliptin and leucine may be beneficial for treating patients with type 2 diabetes and hepatic steatosis; however, further studies are needed to delineate the molecular mechanisms underlying the action of this combination.

ABSTRACT

The gastrointestinal (GI) tract is a series of hollow organs that is responsible for the digestion and absorption of ingested foods and the excretion of waste. Any changes in the GI tract can lead to GI disorders. GI disorders are highly prevalent in the population and account for substantial morbidity, mortality, and healthcare utilization. GI disorders can be functional, or organic with structural changes. Functional GI disorders include functional dyspepsia and irritable bowel syndrome. Organic GI disorders include inflammation of the GI tract due to chronic infection, drugs, trauma, and other causes. Recent studies have highlighted a new explanatory mechanism for GI disorders. It has been suggested that autophagy, an intracellular homeostatic mechanism, also plays an important role in the pathogenesis of GI disorders. Autophagy has three primary forms: macroautophagy, microautophagy, and chaperone-mediated autophagy. It may affect intestinal homeostasis, host defense against intestinal pathogens, regulation of the gut microbiota, and innate and adaptive immunity. Drugs targeting autophagy could, therefore, have therapeutic potential for treating GI disorders. In this review, we provide an overview of current understanding regarding the evidence for autophagy in GI diseases and updates on potential treatments, including drugs and complementary and alternative medicines.

ABSTRACT

Objective@#To assess the safety and clinical efficacy of percutaneous transhepatic enteral stent placement for recurrent malignant obstruction in patients with surgically altered bowel anatomy. @*Materials and Methods@#Between July 2009 and May 2019, 36 patients (27 men and 9 women; mean age, 62.7 ± 12.0 years) underwent percutaneous transhepatic stent placement for recurrent malignant bowel obstruction after surgery. In all patients, conventional endoscopic peroral stent placement failed due to altered bowel anatomy. The stent was placed with a transhepatic approach for an afferent loop obstruction (n = 27) with a combined transhepatic and peroral approach for simultaneous stent placement in afferent and efferent loop obstruction (n = 9). Technical and clinical success, complications, stent patency, and patient survival were retrospectively evaluated. @*Results@#The stent placement was technically successful in all patients. Clinical success was achieved in 30 patients (83.3%). Three patients required re-intervention (balloon dilatation [n = 1] and additional stent placement [n = 2] for insufficient stent expansion). Major complications included transhepatic access-related perihepatic biloma (n = 2), hepatic artery bleeding (n = 2), bowel perforation (n = 1), and sepsis (n = 1). The 3- and 12-months stent patency and patient survival rates were 91.2%, 66.5% and 78.9%, 47.9%, respectively. @*Conclusion@#Percutaneous enteral stent placement using transhepatic access for recurrent malignant obstruction in patients with surgically altered bowel anatomy is safe and clinically efficacious. Transhepatic access is a good alternative route for afferent loop obstruction and can be combined with a peroral approach for simultaneous afferent and efferent loop obstruction.

ABSTRACT

Postoperative ileus (POI), a symptom that occurs after abdominal surgery, reduces gastrointestinal motility. Although its mechanism is unclear, POI symptoms are known to be caused by inflammation 6 to 72 h after surgery. As proton pump inhibitors exhibit protective effect against acute inflammation, the purpose of this study was to determine the effect of ilaprazole on a POI rat model. POI was induced in rats by abdominal surgery. Rats were divided into six groups: control: normal rat + 0.5% CMC-Na, vehicle: POI rat + 0.5% CMC-Na, mosapride: POI rat + mosapride 2 mg/kg, ilaprazole 1 mg/kg: POI rat + ilaprazole 1 mg/kg, ilaprazole 3 mg/kg: POI rat + ilaprazole 3 mg/kg, and ilaprazole 10 mg/kg: POI rat + ilaprazole 10 mg/kg. Gastrointestinal motility was confirmed by measuring gastric emptying (GE) and gastrointestinal transit (GIT). In the small intestine, inflammation was confirmed by measuring TNF-α and IL-1β; oxidative stress was confirmed by SOD, GSH, and MDA levels; and histological changes were observed by H&E staining. Based on the findings, GE and GIT were decreased in the vehicle group and improved in the ilaprazole 10 mg/kg group. In the ilaprazole 10 mg/kg group, TNF-α and IL-1β levels were decreased, SOD and GSH levels were increased, and MDA levels were decreased. Histological damage was also reduced in the ilaprazole-treated groups. These findings suggest that ilaprazole prevents the decrease in gastrointestinal motility, a major symptom of postoperative ileus, and reduces inflammation and oxidative stress.

ABSTRACT

Eupatilin is known to possess anti-apoptotic, anti-oxidative, and antiinflammatoryproperties. We report here that eupatilin has a protective effect onthe ethanol-induced injury in rats. Sprague–Dawley rats were divided into 6 groups:control, vehicle, silymarin, eupatilin 10 mg/kg, eupatilin 30 mg/kg, and eupatilin 100mg/kg. Plasma levels of aspartate aminotransferase (AST) and alanine aminotransferase(ALT) were analyzed to determine the extent of liver damage. Total cholesterol(TC) and triglycerides (TG) were analyzed to determine the level of liver steatosis.Malondialdehyde level, superoxide dismutase (SOD) activity, and glutathione (GSH)level were analyzed to determine the extent of oxidative stress. Tumor necrosis factor(TNF)- and interleukin (IL)-1 were quantified to verify the degree of inflammation.Based on our findings, chronic alcohol treatment significantly changed the serumindexes and liver indicators of the model rats, which were significantly improved byeupatilin treatment. Rats in the eupatilin-treatment group showed reduced levelsof AST, ALT, TG, TC, TNF-, and IL-1, increased SOD activity and GSH levels, and improvedoverall physiology compared to the alcoholic liver disease model rats. H&Estaining also verified the eupatilin-mediated improvement in liver injury. In conclusion,eupatilin inhibits alcohol-induced liver injury via its antioxidant and anti-inflammatoryeffects.

ABSTRACT

Purpose@#To evaluate the safety and efficacy of the newly designed open-cell type self-expandable nitinol stent (NiTi-stent) for peripheral arteries. @*Materials and Methods@#Twenty-eight limbs of 14 minipigs were randomly assigned to the NiTistent group or conventional nitinol stent group. Stents were symmetrically implanted into the iliac arteries of each animal using carotid artery approach and were observed for 1 month (n = 5) and 6 months (n = 9). The angiographic lumen diameter (ALD), late lumen loss, angiographic stenosis, histomorphometric lumen area, neointimal area, and area stenosis were analyzed and compared between the groups. @*Results@#Stent migration, stent fracture, or thrombus formation were not observed in either group. At the 1-month follow-up, the neointimal area (p = 0.008) and area stenosis (p = 0.016) were significantly smaller in the NiTi-stent group than in the control group. At the 6-months followup, the NiTi-stent group showed significantly larger ALD (p = 0.014), less late lumen loss (p = 0.019), less angiographic stenosis (p = 0.014), larger lumen area (p = 0.040), and smaller neointimal area and area stenosis (p = 0.004 and p= 0.014, respectively) compared with the control group. @*Conclusion@#The NiTi-stent is as safe and effective as the conventional nitinol stent and induces less neointimal hyperplasia in a minipig iliac artery model.

ABSTRACT

ymptoms of Parkinson’s disease (PD) caused by loss of dopaminergic neurons are accompanied by movement disorders, including tremors, rigidity, bradykinesia, and akinesia. Non-human primate (NHP) models with PD play an essential role in the analysis of PD pathophysiology and behavior symptoms. As impairments of hand dexterity function can affect activities of daily living in patients with PD, research on hand dexterity function in NHP models with chronic PD is essential. Traditional rating scales previously used in the evaluation of animal spontaneous behavior were insufficient due to factors related to subjectivity and passivity. Thus, experimentally designed applications for an appropriate apparatus are necessary. In this study, we aimed to longitudinally assess hand dexterity function using hand dexterity task (HDT) in NHP-PD models. To validate this assessment, we analyzed the alteration in Parkinsonian tremor signs and the functionality of presynaptic dopaminergic neuron using positron emission tomography imaging of dopamine transporters in these models. In addition, a significant inverse correlation between HDT and DAT level was identified, but no local bias was found. The correlation with intention tremor signs was lower than the resting tremor. In conclusion, the evaluation of HDT may reflect behavioral symptoms of NHP-PD models. Furthermore, HDT was effectively used to experimentally distinguish intention tremors from other tremors.

ABSTRACT

Ischemic stroke results from arterial occlusion and can cause irreversible brain injury. A non-human primate (NHP) model of ischemic stroke was previously developed to investigate its pathophysiology and for efficacy testing of therapeutic candidates; however, fine motor impairment remains to be well-characterized. We evaluated hand motor function in a cynomolgus monkey model of ischemic stroke. Endovascular transient middle cerebral artery occlusion (MCAO) with an angiographic microcatheter induced cerebral infarction. In vivo magnetic resonance imaging mapped and measured the ischemia-induced infarct lesion. In vivo diffusion tensor imaging (DTI) of the stroke lesion to assess the neuroplastic changes and fiber tractography demonstrated three-dimensional patterns in the corticospinal tract 12 weeks after MCAO. The hand dexterity task (HDT) was used to evaluate fine motor movement of upper extremity digits. The HDT was modified for a home cage-based training system, instead of conventional chair restraint training. The lesion was localized in the middle cerebral artery territory, including the sensorimotor cortex. Maximum infarct volume was exhibited over the first week after MCAO, which progressively inhibited ischemic core expansion, manifested by enhanced functional recovery of the affected hand over 12 weeks after MCAO. The total performance time decreased with increasing success rate for both hands on the HDT. Compensatory strategies and retrieval failure improved in the chronic phase after stroke. Our findings demonstrate the recovery of fine motor skill after stroke, and outline the behavioral characteristics and features of functional disorder of NHP stroke model, providing a basis for assessing hand motor function after stroke.

ABSTRACT

Background@#Children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and depression present with different clinical characteristics compared to those without other psychiatric comorbidities (i.e., ADHD alone). This study aimed to determine the differences in clinical characteristics, complaints, and referral routes between patients with ADHD with and without depression. @*Methods@#The study included 1,231 children and adolescents in Korea. The demographic characteristics, referral routes, and chief complaints were identified and analyzed using the subjects’ electronic medical records of their first outpatient visit. @*Results@#The mean age and proportion of female subjects with depression and ADHD (ADHD-D, n=120) were significantly higher than those of patients with ADHD alone (ADHD-O, n=1,111). Furthermore, referral requests by the caregiver (p=0.037) and patient (p=0.006) were significantly higher in the ADHD-D group. In contrast, referrals via schools (p=0.009) and other medical institutions (p<0.001) were significantly higher in the ADHD-O group. There were more complaints of depression, anxiety, mood dysregulation, suicidal ideation, and self-harm behaviors among the patients in the ADHD-D group. However, complaints of inattention were more common among the patients in the ADHD-O group compared to those in the ADHD-D group (p<0.001). @*Conclusion@#This study revealed several differences in the demographic characteristics, referral routes, and chief complaints of the patients and caregivers between patients with ADHD with and without coexisting depression. Further investigations using structured psychiatric diagnostic tools are warranted.

ABSTRACT

Hydrogen sulfide is well-known to exhibit anti-inflammatory and cytoprotective activities, and also has protective effects in the liver. This study aimed to examine the protective effect of hydrogen sulfide in rats with hepatic encephalopathy, which was induced by mild bile duct ligation. In this rat model, bile ducts were mildly ligated for 26 days. Rats were treated for the final 5 days with sodium hydrosulfide (NaHS). NaHS (25 µmol/kg), 0.5% sodium carboxymethyl cellulose, or silymarin (100 mg/kg) was administered intraperitoneally once per day for 5 consecutive days. Mild bile duct ligation caused hepatotoxicity and inflammation in rats. Intraperitoneal NaHS administration reduced levels of aspartate aminotransferase and alanine aminotransferase, which are indicators of liver disease, compared to levels in the control mild bile duct ligation group. Levels of ammonia, a major causative factor of hepatic encephalopathy, were also significantly decreased. Malondialdehyde, myeloperoxidase, catalase, and tumor necrosis factor-α levels were measured to confirm antioxidative and anti-inflammatory effects. N-Methyl-D-aspartic acid (NMDA) receptors with neurotoxic activity were assessed for subunit NMDA receptor subtype 2B. Based on these data, NaHS is suggested to exhibit hepatoprotective effects and guard against neurotoxicity through antioxidant and anti-inflammatory actions.

ABSTRACT

BACKGROUND/AIMS: Colonoscopic surveillance is currently recommended after polypectomy owing to the risk of newly developed colonic neoplasia. However, few studies have investigated colonoscopy surveillance in Asia. This multicenter and prospective study was undertaken to assess the incidence of advanced adenoma based on baseline adenoma findings at 3 years after colonoscopic polypectomy. METHODS: A total of 1,323 patients undergoing colonoscopic polypectomy were prospectively assigned to 3-year colonoscopy surveillance at 11 tertiary endoscopic centers. Relative risks for advanced adenoma after 3 years were calculated according to baseline adenoma characteristics. RESULTS: Among 1,323 patients enrolled, 387 patients (29.3%) were followed up, and the mean follow-up interval was 31.0±9.8 months. The percentage of patients with advanced adenoma on baseline colonoscopy was higher in the surveillance group compared to the non-surveillance group (34.4% vs. 25.7%). Advanced adenoma recurrence was observed in 17 patients (4.4%) at follow-up. The risk of advanced adenoma recurrence was 2 times greater in patients with baseline advanced adenoma than in those with baseline non-advanced adenoma, though the difference was not statistically significant (6.8% [9/133] vs. 3.1% [8/254], P=0.09). Advanced adenoma recurrence was observed only in males and in subjects aged ≥50 years. In contrast, adenoma recurrence was observed in 187 patients (48.3%) at follow-up. Male sex, older age (≥50 years), and multiple adenomas (≥3) at baseline were independent risk factors for adenoma recurrence. CONCLUSIONS: A colonoscopy surveillance interval of 3 years in patients with baseline advanced adenoma can be considered appropriate.

ABSTRACT

Endoscopic retrograde cholangiopancreatography (ERCP) is a useful tool for the diagnosis and management of diseases of the pancreas and biliary tract. However, ERCP has a high risk of procedure-related complications compared with other endoscopic procedures performed in the upper gastrointestinal tract. The most common complications are pancreatitis, cholangitis, hemorrhage, and perforation. Extraluminal hemorrhagic complications after ERCP are relatively rare but potentially life threatening and should be identified and treated immediately. We report a case of subcapsular hepatic hematoma after guidewire injury during ERCP in a 64-year-old woman with choledocholithiasis who had undergone ERCP with guidewire-assisted papillotomy for stone extraction. Although subcapsular hepatic hematoma is a very rare complication after ERCP, it should be considered in the differential diagnosis of patients complaining of abdominal pain after ERCP.

ABSTRACT

Pegylated interferon alpha (PEG-IFN-α) is widely used to treat chronic hepatitis C in combination with ribavirin. Many adverse effects of PEG-IFN-α, such as hematologic, psychologic, dermatologic, immunologic, and other abnormalities, have been reported, and some serious adverse events lead to PEG-IFN-α treatment discontinuation. For very rare adverse events such as panniculitis, there are no established guidelines on whether to continue PEG-IFN-α treatment. Published reports on panniculitis induced by PEG-IFN-α 2a are sparse. Herein we report a case of repeated occurrences of panniculitis in a patient with chronic hepatitis C, leading to treatment cessation.
