RESUMO

Purpose@#The purpose of this study was to identify changes in the experience rate and level of symptoms of visual display terminal syndrome in college students attending online classes during the COVID-19 pandemic. @*Methods@#Data were collected from February 22 to June 8, 2021 at three measurement points. A total of 117 college students were administered a visual display terminal syndrome survey just before online classes (T1), one month after the start of online classes (T2), and three months after the start of online classes (T3). The collected data were analyzed by frequency and percentage, paired t-test, McNemar test, and repeated measures analysis of variance using the IBM SPSS 25.0 program. @*Results@#The intensity of college students’ visual display terminal syndrome during online classes increased at T2 and T3 compared to T1. The rate of experiencing back discomfort or pain increased abruptly at T2 compared to T1. The intensity of college students’ eye related symptoms and skin related symptoms increased at T2 and T3 compared to T1, while the intensity of college students’ psychological symptoms, general body discomfort, and musculoskeletal symptoms increased at T3 compared to T1. @*Conclusion@#The results of this study suggest that self-care programs are needed to prevent visual display terminal syndrome in college students who are in long-term online classes.

RESUMO

Background@#Data on liver cirrhosis (LC) patients undergoing continuous renal replacement therapy (CRRT) are lacking despite the dismal prognosis. We therefore evaluated clinical characteristics and predictive factors related to mortality in LC patients undergoing CRRT. @*Methods@#We performed a retrospective observational study at two tertiary hospitals in Korea. A total of 229 LC patients who underwent CRRT were analyzed. Patients were classified into survivor and non-survivor groups. We used multivariable Cox regression analyses to identify factors predictive of in-hospital mortality. @*Results@#During a median follow-up of 5 days (interquartile range, 1–19 days), in-hospital mortality rate was 66.4%. In multivariable analysis, the Acute Physiology and Chronic Health Evaluation II (APACHE II) score (hazard ratio [HR], 1.03; 95% confidence interval [CI], 1.01–1.06; p = 0.02), Model for End-Stage Liver Disease (MELD) score (HR, 1.08; 95% CI, 1.04–1.11; p 35 mL/kg/hr (HR, 3.13; 95% CI, 1.62–6.05; p = 0.001). Subgroup analysis revealed that a CRRT delivered dose < 25 mL/kg/hr was a significant risk factor for in-hospital mortality among LC patients with a MELD score ≥ 30. @*Conclusion@#High APACHE II score, high MELD score, and low delivered CRRT dose were significant risk factors for in-hospital mortality. CRRT delivered dose impacted mortality significantly, especially in patients with a MELD score ≥ 30.

RESUMO

Purpose@#Cold air is a major environmental factor that exacerbates asthma. Transient receptor potential melastatin family member 8 (TRPM8) is a cold-sensing channel expressed in the airway epithelium. However, its role in airway inflammation remains unknown. We investigated the role of TRPM8 in innate immune responses in bronchial epithelial cells and asthmatic subjects. @*Methods@#The TRPM8 mRNA and protein expression on BEAS2B human bronchial epithelial cells was examined by real-time polymerase chain reaction (PCR), immunofluorescence staining and western blotting. Additionally, interleukin (IL)-4, IL-6, IL-8, IL-13, IL-25 and thymic stromal lymphopoietin (TSLP) levels before and after menthol, dexamethasone and N-(4-tert-butylphenyl)-4-(3-chloropyridin-2-yl) piperazine-1-carboxamide (BCTC) treatments were measured via real-time PCR. TRPM8 protein levels in the supernatants of induced sputum from asthmatic subjects and normal control subjects were measured using enzyme-linked immunosorbent assay, and mRNA levels in sputum cell lysates were measured using real-time PCR. @*Results@#Treatment with up to 2 mM menthol dose-dependently increased TRPM8 mRNA and protein in BEAS2B cells compared to untreated cells (P < 0.001) and concomitantly increased IL-25 and TSLP mRNA (P < 0.05), but not IL-33 mRNA. BCTC (10 μM) significantly abolished menthol-induced up-regulation of TRPM8 mRNA and protein and IL-25 and TSLP mRNA (P < 0.01). TRPM8 protein levels were higher in the supernatants of induced sputum from asthmatic subjects (n = 107) than in those from healthy controls (n = 19) (P < 0.001), and IL-25, TSLP and IL-33 mRNA levels were concomitantly increased (P < 0.001). Additionally, TRPM8 mRNA levels correlated strongly with those of IL-25 and TSLP (P < 0.001), and TRPM8 protein levels were significantly higher in bronchodilator-responsive asthmatic subjects than in nonresponders. @*Conclusions@#TRPM8 may be involved in the airway epithelial cell innate immune response and a molecular target for the treatment of asthma.

RESUMO

PURPOSE: This study was conducted to develop a scale for measuring aggression in adolescents, based on Ajzen's Theory of Planned Behavior (TPB). METHODS: The participants were 38 adolescents in an in-depth study conducted to develop items for indirect measurement, 13 adolescents in a pre-test, and 289 adolescents in the present survey. The collected data were analyzed using content validity, the correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability, and the Cronbach's α. RESULTS: In this study, the most important variable related to aggression was found to be aggression intention. This study included 4 factors of direct measurement and 6 factors of indirect measurement; therefore, 41 questions were developed. Increased levels of aggression were associated with higher scores for attitudes of aggression, subjective norms, perceived behavioral control, and aggression intention. CONCLUSION: We found that the questionnaire used in this study was valid and reliable as a measurement scale to explain aggression in adolescents based on TPB. Aggression intention should be included in aggression prevention programs because it was linked to aggressive behavior.

RESUMO

BACKGROUND: The main factor limiting the increase in brain dead organ donors is low consent rates for organ donation. METHODS: This study is a retrospective analysis of donor records of Korea Organ Donation Agency from 2013 to 2015. Factors related before providing information about organ donation and process of explaining organ donation were analyzed. RESULTS: Donor gender, marital status, religious affiliation, residence area, knowledge of patients' wishes, understanding of brain death status, and the referring system, providing initial information about donation and initial medical staff providing information about donation had a significant influence on decision to donate. Organ donation greatly increased when the donor family knew the patient's intent to donate. As the degree of family understanding of brain death status and the referring system increased, organ donation rate significantly increased. CONCLUSIONS: Providing sufficient information about brain death during the period of delivering medical services as well as activating campaign and public education are essential to improving the positive attitude toward organ donation.

RESUMO

PURPOSE: This study was performed to develop the Fever Education Program (FEP) and evaluate its effects on the knowledge, attitudes, and nursing practice of pediatric nurses. METHODS: The quasi-experimental research strategy used a pretest-posttest nonequivalent control group design. Recruited participants were forty-seven nurses at two pediatric hospitals in G city. The research was conducted from September 1 to October 10, 2015. To test the effects of the FEP, the participants were divided into two groups, an experimental group (n=27) and a control group (n=20). Data were collected prior to and six weeks after the intervention using self-reported questionnaires. Data were analyzed using Fisher's exact test, the χ²-test, t–test, Mann-Whitney U test, and analysis of covariance (ANCOVA) with the SPSS/WIN 19.0 program. RESULTS: Following the FEP intervention, no significant differences were found in nursing practice, but significant differences were found in knowledge (t=3.62, p=0.001) and attitudes (t=4.26, p=0.000) between the experimental group and the control group. CONCLUSION: The results of this study indicate that the FEP could provide an effective nursing intervention to improve knowledge and attitudes toward fever care in pediatric nurses.

RESUMO

Levodropropizine is commonly used as an antitussive drug for acute and chronic cough. It is a non-opioid agent with peripheral antitussive action via the modulation of sensory neuropeptide levels in the airways. Thus, levodropropizine has a more tolerable profile than opioid antitussives. However, we experienced 3 cases of levodropropizine-induced anaphylaxis. Three patients commonly presented with generalized urticaria, dyspnea, and collapse after taking cold medication including levodropropizine. To find out the culprit drug, we performed skin tests, oral provocation tests (OPTs), and basophil activation tests (BATs). Two patients were confirmed as having levodropropizine-induced anaphylaxis by OPTs, and one of them showed positive to skin prick tests (SPTs). The other patient was confirmed by skin tests and BATs. When we analyzed pharmacovigilance data related to levodropropizine collected for 5 years, most cases (78.9%) had allergic reactions, such as rash, urticaria, angioedema, and anaphylaxis. Therefore, physicians should consider that levodropropizine can be a culprit drug, when anaphylaxis occurs after taking anti-cough or common cold medication.

RESUMO

Toluene diisocyanate (TDI) is the most important cause of occupational asthma (OA), and various pathogenic mechanisms have been suggested. Of these mechanisms, neurogenic inflammation is an important inducer of airway inflammation. Transient receptor potential melastatin 8 (TRPM8) is a well-established cold-sensing cation channel that is expressed in both neuronal cells and bronchial epithelial cells. A recent genome-wide association study of TDI-exposed workers found a significant association between the phenotype of TDI-induced OA and the single-nucleotide polymorphism rs10803666, which has been mapped to the TRPM8 gene. We hypothesized that TRPM8 located in airway epithelial cells may be involved in the pathogenic mechanisms of TDI-induced OA and investigated its role. Bronchial epithelial cells were treated with TDI in a dose- and time-dependent manner. The expression levels of TRPM8 mRNA and protein were determined by quantitative real-time polymerase chain reaction and western blotting. TDI-induced morphological changes in the cells were evaluated by immunocytochemistry. Alterations in the transcripts of inflammatory cytokines were examined in accordance with TRPM8 activation by TDI. TRPM8 expression at both the mRNA and protein levels was enhanced by TDI in airway epithelial cells. TRPM8 activation by TDI led to significant increases in the mRNA of interleukin (IL)-4, IL-13, IL-25 and IL-33. The increased expression of the cytokine genes by TDI was partly attenuated after treatment with a TRPM8 antagonist. TDI exposure induces increased expression of TRPM8 mRNA in airway epithelial cells coupled with enhanced expression of inflammatory cytokines, suggesting a novel role of TRPM8 in the pathogenesis of TDI-induced OA.

RESUMO

The basophil activation test (BAT) has been suggested as a complementary method for diagnosing drug allergies. The aim of this study was to evaluate the clinical utility of this test in patients with drug-induced anaphylaxis. In total, 19 patients, all of whom had a history of moderate to severe anaphylaxis, were enrolled. None of the causative drugs had available in vitro tests or reliable skin tests; these drugs included, among others, first and second-generation cephalosporins, H2 blockers, and muscle relaxants. The BAT yielded positive results in 57.9% of the cases, which was similar those results of skin prick and intradermal tests (42.1% and 57.9%, respectively). When basophils were double labelled with CD63 and CD203c, both of which are basophil activation markers, the positive rate was increased from 57.9% to 73.7%. Therefore, the results of this study confirm that the BAT is a quick, reliable, and safe diagnostic tool for patients with drug-induced anaphylaxis.

RESUMO

Bee pollen is pollen granules packed by honey bees and is widely consumed as natural healthy supplements. Bee pollen-induced anaphylaxis has rarely been reported, and its allergenic components have never been studied. A 40-year-old male came to the emergency room with generalized urticaria, facial edema, dyspnea, nausea, vomiting, abdominal pain, and diarrhea 1 hour after ingesting one tablespoon of bee pollen. Oxygen saturation was 91%. His symptoms resolved after injection of epinephrine, chlorpheniramine, and dexamethasone. He had seasonal allergic rhinitis in autumn. Microscopic examination of the bee pollen revealed Japanese hop, chrysanthemum, ragweed, and dandelion pollens. Skin-prick with bee pollen extracts showed positive reactions at 0.1 mg/mL (A/H ratio > 3+). Serum specific IgE to ragweed was 25.2, chrysanthemum 20.6, and dandelion 11.4 kU/L; however, Japanese hop, honey-bee venom and yellow-jacket venom were negative (UniCAP(R), Thermo Fisher Scientific, Uppsala, Sweden). Enzyme-linked immunosorbent assay (ELISA) confirmed serum specific IgE to bee-pollen extracts, and an ELISA inhibition assay for evaluation of cross-allergenicity of bee pollen and other weed pollens showed more than 90% of inhibition with chrysanthemum and dandelion and ~40% inhibition with ragweed at a concentration of 1 microg/mL. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and IgE-immunoblot analysis revealed 9 protein bands (11, 14, 17, 28, 34, 45, 52, 72, and 90 kDa) and strong IgE binding at 28-34 kDa, 45 and 52 kDa. In conclusion, healthcare providers should be aware of the potential risk of severe allergic reactions upon ingestion of bee pollen, especially in patients with pollen allergy.

RESUMO

PURPOSE: The purposes of this study were to develop an infant sleep health education program using a video for SIDS prevention education and to measure the effects of the program. METHODS: The infant sleep health education program consisted of presentations and motor images. The formation of educational material was directed by the systematic design of instruction. Participants in this study were 59 primiparous women from postpartum care centers. The instruments used in this study were criterion referenced test items for knowledge about infant sleep health and confidence inventory. Experimental group I was given the treatment of infant sleep health education program. Experimental group II was given the program using a video reinforcement after 2 weeks. On the other hand, control group was given no treatment. RESULTS: There was a significant increase in knowledge and confidence in the performance of mother's roles of both experimental group I and experimental group II over the control group. No significant difference was founds for knowledge and confidence in the performance of mother's roles between experimental group I and II. CONCLUSION: The results indicate that this program is a very effective intervention for better sleep health in infants by helping the mothers increase confidence in their role performance.

RESUMO

BACKGROUND: Epigallocatechin-3-gallate (EGCG), a major biologically active component of green tea, has anti-cancer activity in human and animal models. We investigated the schedule-dependent effect of EGCG and paclitaxel on growth of NCI-H460 non-small cell lung cancer cells. METHODS: To investigate the combined effect of EGCG (E) and paclitaxel (P), combination indices (CIs) were calculated, and cell cycle analysis was performed. For the effect on cell apoptosis, western blot analysis was also performed. RESULTS: CI analysis demonstrated that both concurrent and sequential E --> P treatments had antagonistic effects (CIs >1.0), but sequential P --> E had synergistic effects (CIs E treatment decreased the expression of Bcl-2 and procaspase-3 and increased poly(ADP-ribose) polymerase (PARP) cleavage; while minimal effects were seen with concurrent or sequential E --> P treatments. CONCLUSION: Concurrent or sequential E --> P treatment had opposite effects to P --> E treatment, where P --> E treatment showed a synergistic effect on growth inhibition of NCI-H460 cells by inducing apoptosis. Thus, the efficacy of EGCG and paclitaxel combination treatment seems to be schedule-dependent.

RESUMO

BACKGROUND AND OBJECTIVES: Pulmonary arterial stenosis is a relatively common complication after corrective operation of congenital heart disease. Unilateral stenosis of pulmonary arteries could result in decrease perfusion of affected lung, pulmonary regurgitation, or elevation of right ventricular pressure. Eventually there are increasing risks of right ventricular failure, arrhythmia, or sudden death. However we have limited data of pulmonary arterial stent in paediatric population as the treatment of branch pulmonary stenosis. This study aimed at validating the effectiveness and investigating complications of pulmonary arterial stent implantation in a single institution during mid-term follow up period. SUBJECTS AND METHODS: A total of 42 patients (50 stents) were implanted for treating branch pulmonary arterial stenosis. We used cardiac catheterization for comparing diameter after stent implantation directly and lung perfusion scan indirectly. We also investigated any adverse effect relating the procedure. RESULTS: Percent stenosis of stenotic lesions were decreased from 54.1+/-10.7% to 22.8+/-12.5% (p<0.001) and degree of decrement in affected lung perfusion was declined from 22.7+/-8.0% to 10.3+/-9.0% (p<0.001) immediately and lasts during mid-term follow up period. Complication rate relating the procedure was 12% (6 out of 12) and there was no mortality case. CONCLUSION: This series showed immediate and short term effectiveness of pulmonary arterial stent in congenital heart defects. We concluded that percutaneous transcatheter implantation of pulmonary arterial stent was safe and effective during short and mid-term follow up period.

RESUMO

BACKGROUND: Neurological deterioration following acute lacunar infarction is not uncommon. Its association with poor clinical outcome is well-known, but little is known about what causes it. This study aimed to elucidate whether 3 stigmas of cerebral microangiopathy, a pathogenesis of lacunar infarction, are associated with neurological deterioration in patients with acute lacunar infarction. METHODS: Patients with acute lacunar infarction who were admitted within 24 hours of onset were identified using a prospective stroke registry. Patients who presented neurological deterioration within 7 days of hospitalization (progressive lacune group) were matched to 4 controls (non-progressive lacune group) for 'onset to arrival time'. Three stigmas of cerebral microangiopathy (leukoaraiosis, cerebral microbleeds, and silent lacunes) were measured using initial brain MRI, and their associations with neurological deterioration were analyzed. RESULTS: During 45 months, a total of 23 patients were identified and matched to 80 controls. Simple comparison of 2 groups showed that those 3 stigmas of cerebral microangiopathy were not significantly associated with neurological deterioration. Hyperlipidemia (p=0.18), history of transient ischemic attack or stroke (p=0.01), initial NIH stroke scale (p=0.07), white blood cell counts (p=0.16), and lesion volume (p=0.03) were possibly different (p's0.5). CONCLUSIONS: This study did not find a relationship between cerebral microangiopathy and neurological deterioration following acute lacunar infarction. The possibility of inadequate power should be noted.

RESUMO

PURPOSE: Tuberculous pleurisy is the most frequent extrapulmonary manifestation of tuberculosis. In spite of adequate treatment, pleural fibrosis is a common complication, but the mechanism has not been elucidated. This study is to determine whether epithelial to mesenchymal transition (EMT) of mesothelial cells occurs in tuberculous pleurisy. MATERIALS AND METHODS: Normal pleural mesothelial cells, isolated from irrigation fluids during operations for primary spontaneous pneumothorax, were characterized by immunofluorescence and reverse transcription polymerase chain reaction (RT-PCR). These cells were treated in vitro with various cytokines, which were produced in the effluents of tuberculous pleurisy. The isolated cells from the effluents of tuberculous pleurisy were analyzed by immunofluorescence and RT-PCR analysis. RESULTS: The isolated cells from the irrigation fluid of primary spontaneous pneumothorax had epithelial characteristics. These cells, with transforming growth factor-beta1 and/or interleukin-1beta treatment, underwent phenotypic transition from epithelial to mesenchymal cells, with the loss of epithelial morphology and reduction in cytokeratin and E-cadherin expression. Effluent analysis from tuberculous pleurisy using immunofluorescence and RT-PCR demonstrated two phenotypes that showed mesenchymal characteristics and both epithelial & mesencymal characteristics. CONCLUSION: Our results suggest that pleural mesothelial cells in tuberculous pleurisy have been implicated in pleural fibrosis through EMT.

RESUMO

BACKGROUND: Medication adherence (MA) is poor among patients with chronic illnesses, such as those involving the risk factors of stroke. However, the impacts of poor MA on the modifiable risk factors of stroke are not well known. METHODS: We evaluated the MA for the control of hypertension, diabetes, hyperlipidemia, and previous ischemic stroke among consecutive patients with ischemic stroke within 7 days of symptom onset. Nonadherence was defined as taking doctor-prescribed medications for less than 3 weeks during the previous month. Demographic data, risk factor profile, stroke mechanism, and baseline score on the National Institutes of Health Stroke Scale (NIHSS) were compared among patients with nonadherence and those without. RESULTS: Among 1133 patients with at least one medicated risk factor, the rates of nonadherence in hypertension, diabetes, hyperlipidemia, and previous ischemic stroke were 18.5%, 15.3%, 30.3%, and 28.1%, respectively. Overall, 27.4% of patients with more than one risk factor presented nonadherence, with a predilection toward being male (male, 63.9% vs. female, 56.1%, p=0.02) and younger (mean age 64.9 years vs. 66.4 years, p=0.01). Stroke severity according to MA did not differ using either crude analysis (NIHSS score: 5.5+/-5.9 vs. 5.4+/-5.5, p=0.71) or multivariable analysis after log transformation. The prevalence of nonadherence was low for large-artery disease and small-vessel occlusion, and high for cardioembolism. CONCLUSIONS: Prestroke poor MA for the major risk factors was common among patients with chronic illnesses, and was more frequent in younger male patients. Stroke severity was not affected by MA during the month preceding stroke.

RESUMO

Synovial fluid (SF) aspiration cytology is a useful diagnostic tool. For patients with gouty arthritis, the diagnosis is confirmed by the presence of monosodium uric acid (MSU) crystals in the SF, and these crystals are long, pointed ended and needle-shaped and they show strongly negative birefringence. Sometimes, it is difficult to diagnosis between gouty arthritis and other type of inflammatory arthritis. We experienced two unusual cases of gouty arthritis that we performed SF analysis for. The first patient was a 35 year old male who presented with relatively typical clinical symptoms with hyperuricemia, but the SF showed acute inflammatory cells without crystals on light microscopy. Only a few suspected crystals of MSU were identified on polarizing microscopy. The second patient was a 45 year old male who presented with atypical symptoms and pain and swelling of the left ankle and knee joint for 3 weeks. The uric acid level in the serum and urine was increased, but not over the normal limit. However, on light and polarizing microscopy, there were numerous MSU crystals in the SF. Conclusively, in some cases of gouty arthritis, the crystals are not identified on light microscopy or the uric acid level is not dramatically increased. So, the polarizing microscopy, the clinical information and the laboratory findings are all included in the work-up when evaluating the SF cytology of arthritis patients.

RESUMO

PURPOSES: The purposes of this study were to identify factors related to burden and well-being in primary caregivers of patients who have had a stroke and examine the correlation between burden and well-being of the caregivers. METHODS: Between April 2006 to June 2007 data were collected using self-report questionnaires and interviews with 85 primary caregivers of stroke patients in C University Hospital. Data were analyzed using t-test, ANOVA, Duncan test and Pearson's correlation with SPSSWIN 15.0. RESULTS: Factors related to burden of primary caregivers were sex and activities of daily living of the patients, and age, education level and satisfaction with income of the caregivers. The factors related to well-being of primary caregivers were sex of patients, and age and education level of caregivers as well as cohabitation with the patient. A negative correlation was found between burden and well-being of the caregivers (r= -.393, p<.001). CONCLUSION: These results indicate a need to develop a nursing intervention program for caregivers and education program for other family members to reduce caregiver burden. These programs should lead to improvements in the well-being of the caregiver.
