ABSTRACT
Background@#Obesity, the prevalence of which is increasing due to the lack of exercise and increased consumption of Westernized diets, induces various complications, including ophthalmic diseases. For example, obesity is involved in the onset of cataracts. @*Methods@#To clarify the effects and mechanisms of midodrine, an α1-adrenergic receptor agonist, in cataracts induced by obesity, we conducted various analytic experiments in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a rat model of obesity. @*Results@#Midodrine prevented cataract occurrence and improved lens clearance in OLETF rats. In the lenses of OLETF rats treated with midodrine, we observed lower levels of aldose reductase, tumor necrosis factor-α, and sorbitol, but higher levels of hexokinase, 5’-adenosine monophosphate-activated protein kinase-alpha, adenosine 5´-triphosphate, peroxisome proliferator-activated receptordelta, peroxisome proliferator-activated receptor gamma coactivator 1-alpha, superoxide dismutase, and catalase. @*Conclusion@#The ameliorating effects of midodrine on cataracts in the OLETF obesity rat model are exerted via the following three mechanisms: direct inhibition of the biosynthesis of sorbitol, which causes cataracts; reduction of reactive oxygen species and inflammation; and (3) stimulation of normal aerobic glycolysis.
ABSTRACT
Purpose@#We used the Bayley Scales of Infant and Toddler Development (BSID)-III to analyze the incidence and risk factors of developmental delay in very-low-birth-weight infants without severe brain lesions. We further examined the correlation between the cumulative dexamethasone dose and developmental assessment results. @*Methods@#We retrospectively analyzed data of preterm infants (birth weight <1,500 g) admitted to our neonatal intensive care unit between January 2014 to December 2020. The BSID-III scores obtained between the corrected ages of 12 and 24 months and after 24 months were analyzed. Developmental delay was defined as a composite score of <85 for the cognition, language, and motor domains. Univariate and multivariate analyses of developmental delay risk factors and developmental changes from the first to second BSID-III were performed. Correlations between the accumulated dexamethasone dose used for bronchopulmonary dysplasia (BPD) and the first and second test scores were analyzed. @*Results@#Seventy-one and thirty-six infants completed the first and second tests, respectively. In both tests, developmental delay was most commonly observed in the language domain (26.8%, 47.2%). In multivariate analysis, mild BPD was identified as a developmental delay risk factor (P<0.05), whereas prenatal steroid use reduced the developmental delay risk (P<0.05). All domain scores were lower in the second test than in the first test. The cognition and language domain scores in the second test decreased with increasing cumulative dexamethasone doses. @*Conclusion@#Very-low-birth-weight infants typically experience language delay, which can persist as they age.
ABSTRACT
Purpose@#Since premature infants are sensitive to the changes in blood glucose levels and body temperature, maintaining these parameters is important to avoid the risk of infections. The authors implemented the Golden Hour protocol (GHP) that aims to close the final incubator within one hour of birth by implementing early treatment steps for premature infants after birth, such as maintaining body temperature, securing airway, and rapidly administering glucose fluid and prophylactic antibiotics by securing breathing and rapid blood vessels. This study investigated the effect of GHP application on the short- and long-term clinical outcomes. @*Methods@#We retrospectively analyzed the medical records between 2017 and 2018 before GHP application and between 2019 and 2020 after GHP application in preterm infants aged 24 weeks or older and those aged less than 33 weeks who were admitted to the neonatal intensive care unit. @*Results@#Overall, 117 GHP patients and 81 patients without GHP were compared and analyzed. Peripheral vascularization time and prophylactic antibiotic administration time were shortened in the GHP-treated group (P=0.007 and P=0.008). In the short-term results, the GHP-treated group showed reduced hypothermia upon arrival at the neonatal intensive care unit (P=0.002), and the blood glucose level at 1 hour of hospitalization was higher (P=0.012). Furthermore, the incidence of neonatal necrotizing enteritis decreased (P=0.043). As a long-term result, the incidence of BPD was reduced (P=0.004). @*Conclusion@#We confirmed that applying GHP improved short- and long-term clinical outcomes in premature infants aged <33 weeks age of gestation, and we expect to improve the treatment quality by actively using it for postnatal treatment.
ABSTRACT
Purpose@#Since diabetes and hypertension frequently occur together, it is thought that these conditions may have a common pathogenesis. This study was designed to evaluate the anti-diabetic function of the anti-hypertensive drug fimasartan on C2C12 mouse skeletal muscle and HepG2 human liver cells in a high glucose state. @*Materials and Methods@#The anti-diabetic effects and mechanism of fimasartan were identified using Western blot, glucose uptake tests, oxygen consumption rate (OCR) analysis, adenosine 5'-triphosphate (ATP) enzyme-linked immunosorbent assay (ELISA), and immunofluorescence staining for diabetic biomarkers in C2C12 cells. Protein biomarkers for glycogenolysis and glycogenesis were evaluated by Western blotting and ELISA in HepG2 cells. @*Results@#The protein levels of phosphorylated 5' adenosine monophosphate-activated protein kinase (p-AMPK), p-AKT, insulin receptor substrate-1 (IRS-1), and glucose transporter type 4 (Glut4) were elevated in C2C12 cells treated with fimasartan. These increases were reversed by peroxisome proliferator-activated receptor delta (PPARδ) antagonist. ATP, OCR, and glucose uptake were increased in cells treated with 200 μM fimasartan. Protein levels of glycogen phosphorylase, glucose synthase, phosphorylated glycogen synthase, and glycogen synthase kinase-3 (GSK-3) were decreased in HepG2 cells treated with fimasartan. However, these effects were reversed following the addition of the PPARδ antagonist GSK0660. @*Conclusion@#In conclusion, fimasartan ameliorates deteriorations in glucose metabolism as a result of a high glucose state by regulating PPARδ in skeletal muscle and liver cells.
ABSTRACT
Osteoarthritis (OA) is one of the most disabling dis¬eases with high incidence, which involves the entire joint and its diseased tissues include cartilage, subchondral bone and synovi¬um.For the exploration of its pathogenesis, the current research focuses on: ( 1 ) cartilage damage caused by cartilage metabo¬lism imbalance.'Hie reasons include aging, trauma, obesity, biological rhythm changes, biological mechanics and other fac¬tors: (2) abnonnal bone remodeling of subchondral bone, resul¬ting in subchondral bone sclerosis and bone spurs; ( 3 ) cartilage debris leads to synovial inflammation caused by synovial macro¬ phages and T cells.At present, there have been clinical and pre-clinical studies of a variety of targeted small molecule drugs for the above symptoms.This review focuses on the current un¬derstanding of the underlying pathogenesis of OA, and emphasi-zes the important role of chondrocytes, macrophages, and osteo¬clasts, as well as the latest research progress in drug therapy at this stage.
ABSTRACT
Circadian disruption often involves a neurodegenerative disorder, such as Alzheimer’s disease or frontotemporal dementia, which are characterized by intraneuronal tau accumulations. The altered sleep pattern and diurnal rhythms in these disorders are the results of tau pathology. The circadian disturbance in reverse is thought to develop and potentially aggravate the condition. However, the underlying mechanism is not fully understood. In this study, perturbed oscillations in BMAL1, the core clock gene, were observed in P301S tau transgenic mice. Tau fractionation analysis of the hippocampus revealed profound fluctuations in soluble and insoluble tau protein levels that were in opposite directions to each other according to zeitgeber time. Interestingly, a diurnal oscillation was detected in the heat shock 70 kDa protein 1A (Hsp70) chaperone that was in-phase with soluble tau but out-of-phase with insoluble tau. Tau protein levels decreased in the soluble and insoluble fractions when Hsp70 was overexpressed in HEK293T cells. Transfection of the BMAL1 carrying vector was continual with the increase in Hsp70 expression and diminished tau protein levels, and it was effectively attenuated by the knockdown of Hsp70, suggesting that BMAL1 could modulate tau protein by Hsp70. Our results suggest that altered circadian oscillations affect tau status and solubility by modulating Hsp70 expression in an experimental model of tau pathology. These findings suggest Hsp70 as a possible pathogenic link between circadian disruption and aggravations of tau pathology.
ABSTRACT
Purpose@#This study aimed to identify prognostic factors based on treatment outcomes for congenital diaphragmatic hernia (CDH) at a single-center and to identify factors that may improve these outcomes. @*Methods@#Thirty-five neonates diagnosed with CDH between January 2011 and December 2021 were retrospectively analyzed. Pre- and postnatal factors were correlated and analyzed with postnatal clinical outcomes to determine the prognostic factors. Highest oxygenation index (OI) within 24 hours of birth was also calculated. Treatment strategy and outcome analysis of published literatures were also performed. @*Results@#Overall survival rate of this cohort was 60%. Four patients were unable to undergo anesthesia and/or surgery. Three patients who commenced extracorporeal membrane oxygenation (ECMO) post-surgery were non-survivors. Compared to the survivor group, the non-survivor group had a significantly higher occurrence of pneumothorax on the first day, need for high-frequency ventilator and inhaled nitric oxide use, and high OI within the first 24 hours. The non-survivor group showed an early trend towards the surgery timing and a greater number of patch closures. Area under the receiver operating characteristic curve was 0.878 with a sensitivity of 76.2% and specificity of 92.9% at an OI cutoff value of 7.75. @*Conclusion@#OI within 24 hours is a valuable predictor of survival. It is expected that the application of ECMO based on OI monitoring may help improve the opportunity for surgical repair, as well as the prognosis of CDH patients.
ABSTRACT
Chronic obstructive pulmonary disease (COPD) is a common and frequently-occurring disease of the respiratory system, characterized by persistent respiratory symptoms and airflow restriction, which is prone to attack repeatedly and affect patients' quality of life seriously. At present, the combination of bronchodilators and inhaled corticosteroids is commonly used in clinic. Although these drugs can alleviate the symptoms of COPD patients, there are certain limitations of the difficulty in controlling the course of the disease effectively and reversing the decline of patients' lung function. Therefore, searching for safer and more effective therapeutic drugs has become a hot research topic nowadays. Traditional Chinese medicine (TCM) has remarkable curative effects and advantages in the prevention and therapy of COPD recently. Based on the increasing research and application of the active components of TCM in the therapy of COPD, studies on their pharmacodynamic mechanism are also more in depth. More and more studies have found that the active components of TCM can treat COPD patients effectively, and the mechanism involved mainly includes the anti-inflammatory, the antioxidant, and the inhibition of apoptosis. By searching and screening the domestic and foreign literatures on the treatment of COPD with the active components of TCM in recent years, the active components of TCM including flavonoids, terpenoids, phenols and saponins have been studied as the research objects, and their effects in improving the pulmonary function and oxidative stress, relieving inflammation and inhibiting apoptosis are expounded. Besides, the mechanism of action, signaling pathways and index molecules have been emphatically summarized, in order to provide the ideas for the clinical therapy and the basic research of COPD.
ABSTRACT
Purpose@#Syphilis infections are becoming more prevalent in the Republic of Korea, and inadequately treated syphilis can lead to congenital syphilis (CS) in newborns. This study aimed to analyze the clinical manifestations of syphilis in mothers and newborns and to make suggestions to improve disease prognosis. @*Methods@#This single-center study was performed between August 2009 and August 2019 and included 29 newborns with CS. We retrospectively evaluated the clinical features, rapid plasma reagin (RPR) card test, fluorescent treponemal antibody absorption test (FTA-ABS), morbidity, and treatment regimen of all the syphilis-affected mothers and their newborns. @*Results@#At the time of delivery, mean maternal age was 29.0±6.1 years old, and newborn gestational age was 38.0 weeks. In cases when syphilis was confirmed during the second and third trimesters of pregnancy, the newborn with CS had morbidity (p=0.004). The mean RPR titer was related to morbidity (p= 0.036). Positive results of FTA-ABS IgM (p<0.001) and pleocytosis in the cerebrospinal fluid (CSF) (p= 0.020) also increase morbidity. The most common symptoms were desquamation and skin rash, followed by hepatomegaly, neurodevelopmental disability, and bone abnormalities. The highest number of CS cases per 1,000 live births in this hospital was in 2014. @*Conclusion@#CS is a preventable and treatable disease if physicians detect symptoms and provide appropriate treatment through RPR examinations during every trimester. General practitioners should be widely trained on various aspects including early detection, formal treatment, and regular follow-up. Additionally, medical services should be provided for the entire childbearing population regardless of the socioeconomic status.

ABSTRACT
Purpose@#Despite the importance of mental health-related quality of life among workers, its comprehensive understanding is lacking. This study aimed to identify influencing factors regarding mental health-related quality of life through a comprehensive literature review. @*Methods@#The integrative review method of Whittemore and Knaf was used. Data search was conducted on papers published before September 2020, and RISS, NDSL, and KISS were used for the search. @*Results@#Fourteen studies were selected for analysis. Five factors affecting the mental health-related quality of life of workers were found. Mental and physical health status, job stress, working environment, health behaviors, and other personal and socio-economic characteristics were significant influencing factors. @*Conclusion@#Findings from the review suggest the necessity of developing a customized intervention program to improve the mental health-related quality of life of workers.
ABSTRACT
PURPOSE: Hospice volunteers are serving an invisible yet pivotal role in the hospice and palliative care team. This study investigated how effectively a continuing education program could enhance hospice volunteers' competency.METHODS: A total of 20 hours (four hours per week) of training was provided to 30 hospice volunteers who participated in the continuing education for hospice volunteers. Efficiency of the education was analyzed with an exploratory mixed-methods design. For quantitative analysis, the volunteers were asked, before and after the training, about their attitudes towards hospice care, what makes a meaningful life, self-efficacy and satisfaction with their volunteer service. Descriptive statistics, paired t-tests, and Wilcoxon signed-rank test were performed using SPSS Window 20.0. For qualitative research, participants were placed in three groups for a focus group interview, and data were analyzed by content analysis.RESULTS: A quantitative study result shows that this training can significantly affect hospice volunteers' attitudes and improve their self-efficacy. A qualitative study result shows that participants wanted to receive continuous education from the physical/psychosocial/spiritual aspects to better serve end-of-life patients and their family members even though they have to spare significant time for the volunteer service. They wanted to know how to take good care of patients without getting themselves injured and how to provide spiritual care.CONCLUSION: The continuing education program reflecting volunteers' requests is strongly needed to improve their competency. An effective continuing education requires continuous training and support in areas where hospice volunteers are interested in. A good alternative is to combine web-based and hands-on training, thereby allowing hospice volunteers freely take training that suits their interest.

PURPOSE: This study aimed to investigate the prevalence of delayed thyroid dysfunction based on iodine disinfectant use and to analyze associated risk factors.METHODS: A retrospective study was conducted on late preterm infants admitted to the neonatal intensive care unit between January 2010 and June 2018, who underwent neonatal thyroid screening (NTS) and ≥2 thyroid function tests (TFTs). NTS was performed 3 days after birth, with at least two TFTs 1 week and 2 to 4 weeks after birth. To distinguish between normal and dysfunctional thyroid levels, we reviewed TFT results at 2 to 4 weeks and examined possible risk factors for the development of thyroid dysfunction.RESULTS: Of 295 late preterm infants, 262 were enrolled with a mean gestational age and birth weight of 34.8±0.7 weeks and 2,170±454 g, respectively. A total of 7.6% developed hyperthyrotropinemia at the age of 24.3±14.6 days (range, 12 to 69). The incidence of hyperthyrotropinemia during iodine use was approximately 12.6%, while that during discontinuation was 2.4% (P=0.002). Multivariate analysis revealed that small for gestational age (SGA), iodine disinfectant use, and abnormal NTS results were significant risk factors for delayed hyperthyrotropinemia (adjusted odds ratio [AOR]: 4.27, P=0.008; AOR: 8.24, P=0.003; and AOR: 7.80, P=0.002, respectively).CONCLUSION: Delayed hyperthyrotropinemia was prevalent in late preterm infants exposed to topical iodine and those identified as being SGA. Secondary TFTs should be considered 2 to 4 weeks after birth for this population at risk.

PURPOSE: To analyze the growth response to growth hormone (GH) therapy in prepubertal patients with Noonan syndrome (NS) harboring different genetic mutations. METHODS: Twenty-three patients with prepubertal NS treated at Pusan National University Children’s Hospital between March 2009 and July 2017 were enrolled. According to the disease-causing genes identified, the patients with NS were divided into 4 groups. Three groups were positive for mutations of the PTPN11, RAF1, and SOS1 genes. The five genes undetected (FGU) group was negative for PTPN11, RAF1, SOS1, KRAS, and BRAF gene mutations. The influence of genotype was retrospectively analyzed by comparing the growth parameters after GH therapy. RESULTS: The mean chronological age at the start of GH treatment was 5.85±2.67 years. At the beginning of the GH treatment, the height standard deviation score (SDS), growth velocity (GV), and lower levels of insulin-like growth factor-1 (IGF)-1 levels were not statistically different among the groups. All the 23 NS patients had significantly increased height SDS and serum IGF-1 level during the 3 years of treatment. GV was highest during the first year of treatment. During the 3 years of GH therapy, the PTPN11, RAF1, and SOS1 groups showed less improvement in height SDS, IGF-1 SDS, and GV, and less increase in bone age-to-chronological age ratio than the FGU group. CONCLUSION: The 3-year GH therapy in the 23 prepubertal patients with NS was effective in improving height SDS, GV, and serum IGF-1 levels. The FGU group showed a better response to recombinant human GH therapy than the PTPN11, RAF1, and SOS1 groups.

Herpes simplex virus (HSV) is a common pathogen, that causes a broad spectrum of diseases, ranging from minor skin infections to severe encephalitis and widespread infections. Acute retinal necrosis (ARN), one of the most serious manifestations of HSV infection, is defined as a rapidly progressing necrotizing retinopathy that presents discrete areas of circumferential retinal necrosis, along with signs of uveitis, vitreitis, and retinal vasculitis. We encountered a case of a female infant, born at 33 weeks of gestation with a body weight at birth of 2,080 g, who had ARN and encephalomalacia due to HSV infection. ARN associated with HSV infection should be suspected when nonspecific retinal exudates are observed in neonates, especially preterm infants.

PURPOSE: To analyze and compare the clinical factors and neurodevelopmental outcomes compare early- and late-onset periventricular leukomalacia (PVL) in very low birth weight infants (VLBWI). METHODS: We performed a retrospective study involving 199 newborn infants weighing < 1,500 g admitted to the neonatal intensive care unit between March 2009 and December 2015. VLBWI with PVL were categorized into early- and late-onset PVL groups based on the time of diagnosis based on 28 days of age. We analyzed the clinical factors and neurodevelopmental outcomes between the groups. RESULTS: The incidence rate of PVL was 10.1% (16/158). The Apgar score at 1 minute and the mean duration of tocolytic therapy were associated with the development of PVL. The incidence rate of premature rupture of membranes (PROM) was significantly higher in the early-onset PVL group (P=0.041). No significant differences were observed in neurodevelopmental outcomes between the early- and late-onset PVL groups. CONCLUSION: Results suggest that a higher incidence of PROM was associated with clinical characteristics in the early-onset PVL group. No significant intergroup differences were observed in neurodevelopmental outcomes; however, the Bayley Scales of Infant Development-III scores were lower in the early-onset PVL group.

3D histology is a imaging system for the 3D structural information of cells or tissues. The synchrotron radiation propagation phase contrast micro-CT has been used in 3D imaging methods. However, the simple phase contrast micro-CT did not give sufficient micro-structural information when the specimen contains soft elements, as is the case with many biomedical tissue samples. The purpose of this study is to develop a new technique to enhance the phase contrast effect for soft tissue imaging. Experiments were performed at the imaging beam lines of Pohang Accelerator Laboratory (PAL). The biomedical tissue samples under frozen state was mounted on a computer-controlled precision stage and rotated in 0.18° increments through 180°. An X-ray shadow of a specimen was converted into a visual image on the surface of a CdWO4 scintillator that was magnified using a microscopic objective lens (X5 or X20) before being captured with a digital CCD camera. 3-dimensional volume images of the specimen were obtained by applying a filtered back-projection algorithm to the projection images using a software package OCTOPUS. Surface reconstruction and volume segmentation and rendering were performed were performed using Amira software. In this study, We found that synchrotron phase contrast imaging of frozen tissue samples has higher contrast power for soft tissue than that of non-frozen samples. In conclusion, synchrotron radiation propagation phase contrast cryo-microCT imaging offers a promising tool for non-destructive high resolution 3D histology.

BACKGROUND: At least 30 minutes of pre-warming has been recommended for the prevention of redistribution hypothermia. However, it has been reported that less than 30 minutes of pre-warming is also effective. The aim of this study was to evaluate the ability of 10 minutes of pre-warming to prevent inadvertent perioperative hypothermia. Results were compared with 30 minutes of pre-warming. METHODS: In this prospective randomized study, 59 patients scheduled for elective surgery less than 120 minutes under general anesthesia were divided into 2 groups: the first group was pre-warmed for 10 minutes (n = 30), the second group for 30 minutes (n = 29). The patients were pre-warmed for 10 or 30 minutes in the pre-anesthetic area using a forced-air warmer. When the patients' body temperatures decreased below 36℃, we warmed them with a forced-air warmer intraoperatively and postoperatively. Body temperatures were recorded during perioperative periods. Shivering and thermal comfort were evaluated in the pre-anesthetic area and post-anesthesia care unit. RESULTS: The incidence of intraoperative and postoperative hypothermia were not significantly different (P > 0.05). However, the temperatures were higher in the 30 minute group from the post-warming time to 90 minutes after anesthetic induction (P < 0.05). CONCLUSIONS: Ten minutes of pre-warming has the same effectiveness as 30 minutes of pre-warming for preventing inadvertent perioperative hypothermia. It is a preferable choice for the patients scheduled for surgery less than 120 minutes under general anesthesia.

Esophageal atresia (EA) with proximal tracheoesophageal fistula (TEF; gross type B) is a rare defect. Although most patients have long-gap EA, there are still no established surgical guidelines. A premature male infant with symmetric intrauterine growth retardation (birth weight, 1,616 g) was born at 35 weeks and 5 days of gestation. The initial diagnosis was pure EA (gross type A) based on failure to pass an orogastric tube and the absence of stomach gas. A “feed and grow” approach was implemented, with gastrostomy performed on postnatal day 2. A fistula was detected during bronchoscopy for recurrent pneumonia; thus, we confirmed type B EA and performed TEF excision and cervical end esophagostomy. As the infant's stomach volume was insufficient for bolus feeding after reaching a body weight of 2.5 kg, continuous tube feeding was provided through a gastrojejunal tube. On the basis of these findings, esophageal reconstruction with gastric pull-up was performed on postnatal day 141 (infant weight, 4.7 kg), and he was discharged 21 days postoperatively. At 12 months after birth, there was no catch-up growth; however, he is currently receiving a baby food diet without any complications. In patients with EA, bronchoscopy is useful for confirming TEF, whereas for those with long-gap EA with a small stomach volume, esophageal reconstruction with gastric pull-up after continuous feeding through a gastrojejunal tube is worth considering.

BACKGROUND: The aim of this study was to evaluate aprepitant in combination with palonosetron as compared to palonosetron alone for the prevention of postoperative nausea and vomiting (PONV) in female patients receiving fentanyl- based intravenous patient-controlled analgesia (IV-PCA). METHODS: In this randomized single-blinded study, 100 female patients scheduled for elective surgery under general anesthesia were randomized to two groups: Group AP (80 mg aprepitant plus 0.075 mg palonosetron, n = 50) and Group P (0.075 mg palonosetron, n = 50). The patients in group AP received 80 mg aprepitant per oral 1–3 h before surgery, while all patients received 0.075 mg palonosetron after induction of standardized anesthesia. All patients had postoperative access to fentanyl-based IV-PCA. The incidence of nausea and vomiting, use of rescue medication, and severity of nausea were evaluated at 6 and 24 h after surgery. RESULTS: The incidence of nausea (54%) and vomiting (2%) in group AP did not differ significantly from that in group P (48% and 14%, respectively) during the first 24 h after surgery (P > 0.05). Patient requirements for rescue medication in group AP (29%) were similar to those in group P (32%) at 24 h after surgery (P > 0.05). There was no difference between the groups in severity of nausea during the first 24 h after surgery (P > 0.05). CONCLUSIONS: Aprepitant combined with palonosetron did not reduce the incidence of PONV as compared to palonosetron alone within 24 h of surgery in women receiving fentanyl-based IV-PCA.
