RESUMO
Human papillomavirus (HPV) is an important causative factor of cervical cancer and is associated with nonsmall cell lung cancer (NSCLC). Merkel cell polyomavirus (MCPyV) is a rare and highly fatal cutaneous virus that can cause Merkel cell carcinoma (MCC). Although coinfection with oncogenic HPV and MCPyV may increase cancer risk, a definitive etiological link has not been established. Recently, genomic variation and genetic diversity in the MCPyV noncoding control region (NCCR) among ethnic groups has been reported. The current study aimed to provide accurate prevalence information on HPV and MCPyV infection/coinfection in NSCLC patients and to evaluate and confirm Korean MCPyV NCCR variant genotypes and sequences. DNA from 150 NSCLC tissues and 150 adjacent control tissues was assessed via polymerase chain reaction (PCR) targeting regions of the large T antigen (LT-ag), viral capsid protein 1 (VP1), and NCCR. MCPyV was detected in 22.7% (34 of 150) of NSCLC tissues and 8.0% (12 of 150) of adjacent tissues from Korean patients. The incidence rates of HPV with and without MCPyV were 26.5% (nine of 34) and 12.9% (15 of 116). The MCPyV NCCR genotype prevalence in Korean patients was 21.3% (32 of 150) for subtype I and 6% (nine of 150) for subtype IIc. Subtype I, a predominant East Asian strain containing 25 bp tandem repeats, was most common in the MCPyV NCCR data set. Our results confirm that coinfection with other tumor-associated viruses is not associated with NSCLC. Although the role of NCCR rearrangements in MCPyV infection remains unknown, future studies are warranted to determine the associations of MCPyV NCCR sequence rearrangements with specific diseases.

PURPOSE: To identify and understand the key family resilience factors that contribute to the improved family adaptation of children with epilepsy. METHODS: Parent of children with epilepsy treated in the outpatient unit and general ward at Severance Children's Hospital in Seoul, Korea, completed a structured online questionnaire between April and May 2023. This study examined risk (epilepsy severity, time since diagnosis, parental depression, and perceived stigma) and protective factors (child temperament, epilepsy knowledge, family communication skills, parent's educational level, monthly household income, and social support) of family adaptation based on Patterson's Family Resilience Model. Furthermore, general characteristics such as daily caregiving time, perceived parental health, family type, and primary caregiver role were analyzed. RESULTS: This study included 131 participants with a mean age of 41.79 ± 5.77 years, with children having an average age of 9.19 ± 4.94 years. The regression model was significant, and revealed the impact of communication skills, social support, and primary caregivers other than parents. Moreover, a shorter time since diagnosis has a more positive impact on family adaptation. CONCLUSIONS: To improve family adaptation in children with epilepsy, the focus should be placed on improving communication skills, increasing social support, and providing access to external support services. Furthermore, families expecting longer illness duration require proactive measures to support them. These findings could guide future strategies to enhance adaptation in families with children with epilepsy.

PURPOSE: The rising prevalence of smartphone overdependence among adolescents and its detrimental impact on mental health have become a growing concern. This study aimed to investigate the association between smartphone overdependence and the mental health of Korean adolescents. METHODS: Participants were drawn from the 16th Korea Youth Risk Behavior Web-based Survey conducted in 2020. The dependent variable as smartphone overdependence, while the main exposure of interest was mental health, encompassing generalized anxiety disorder (GAD), perceived stress, sources of perceived stress, perceived loneliness, and perceived depressive symptoms. The study employed the Rao-Scott chi-square test and multiple logistic regression using IBM SPSS version 26.0. RESULTS: The participants comprised 54,948 adolescents aged 13 to 18 years. Among them, 25.1% (n=13,775) were categorized as smartphone overdependence group. Specifically, 20.3% of adolescents who reported GAD ≥10 and 22.5% of those who reported experiencing high levels of perceived loneliness were identified as smartphone overdependent. The GAD increased a risk of smartphone overdependence by 2.61 times (95% confidence interval [95% CI]: 2.46-2.77). Perceived loneliness was associated with 1.98-fold (95% CI: 1.87-2.09) increased risk of smartphone overdependence. Additionally, conflict with peers was found to increase the risk of smartphone overdependence by 4.63-fold (95% CI: 3.89-5.52), followed by conflict with parents (odds ratio [OR]: 4.52, 95% CI: 3.84-5.31), and family environment (OR: 4.52, 95% CI: 3.75-5.46). CONCLUSION: The findings underscore a significant association between smartphone overdependence and mental health in Korean adolescents. Healthcare services to improve their emotional coping and interpersonal skills are necessary.
RESUMO
INTRODUCTION: Nonimmersive virtual reality (NIVR), a computer-generated virtual reality experience wherein users are not fully immersed, has been increasingly used in pediatric healthcare. This study aimed to identify the effects of NIVR-based interventions for children. METHOD: A mixed methods systematic review of relevant studies published until December 2023 was conducted. We included samples of healthy children and those with chronic conditions or disabilities, findings related to self-management or social skills, and the NIVR interventions applied. A convergent-integrated design was used for the synthesis. RESULTS: This review included 22 studies, of which 15 examined children having autism spectrum disorders. Utilizing NIVR was found to be effective in enhancing social skills. Participating in virtual communities with peers having similar conditions was determined to facilitate social support and identity exploration. DISCUSSION: Healthcare interventions using NIVR need to be explored further to improve self-management and social skills in children with various conditions.
RESUMO
BACKGROUND: Delirium is a serious complication experienced by hospitalized children. Therefore, preventive management strategies are recommended for these patients. However, comprehensive analyses of delirium interventions in children remain insufficient. Specifically, this systematic review aimed to summarize non-pharmacological interventions for pediatric delirium, addressing the urgent need for a comprehensive understanding of effective strategies. We also explored frequently measured outcome variables to contribute evidence for future research on delirium outcomes in children. METHODS: This systematic review searched articles from PubMed, Web of Science, Cumulative Index to Nursing and Allied Health Literature, and Excerpta Medica databases. The eligibility criteria were formed under the population, intervention, comparator, outcome, and study design framework. Studies were included if they involved (1) children aged under 18 years receiving hospital care, (2) non-pharmacological delirium interventions, (3) comparators involving no intervention or pharmacological delirium interventions, and (4) outcomes measuring the effectiveness of non-pharmacological delirium interventions. Only peer-reviewed articles published in English were included. RESULTS: Overall, 16 studies were analyzed; of them, 9 assessed non-pharmacological interventions for emergence delirium and 7 assessed interventions for pediatric delirium. The intervention types were grouped as follows: educational (n = 5), multicomponent (n = 6), and technology-assisted (n = 5). Along with pediatric and emergence delirium, the most frequently measured outcome variables were pain, patient anxiety, parental anxiety, pediatric intensive care unit length of stay, agitation, analgesic consumption, and postoperative maladaptive behavior. CONCLUSIONS: Non-pharmacological interventions for children are effective treatments without associated complications. However, determining the most effective non-pharmacological delirium intervention for hospitalized children based on current data remains challenging.

We recently established a long-term SARS-CoV-2 infection model using lung-cancer xenograft mice and identified mutations that arose in the SARS-CoV-2 genome during long-term propagation. Here, we applied our model to the SARS-CoV-2 Delta variant, which has increased transmissibility and immune escape compared with ancestral SARS-CoV-2. We observed limited mutations in SARS-CoV-2 Delta during long-term propagation, including two predominant mutations: R682W in the spike protein and L330W in the nucleocapsid protein. We analyzed two representative isolates, Delta-10 and Delta-12, with both predominant mutations and some additional mutations. Delta-10 and Delta-12 showed lower replication capacity compared with SARS-CoV-2 Delta in cultured cells; however, Delta-12 was more lethal in K18-hACE2 mice compared with SARS-CoV-2 Delta and Delta-10. Mice infected with Delta-12 had higher viral titers, more severe histopathology in the lungs, higher chemokine expression, increased astrocyte and microglia activation, and extensive neutrophil infiltration in the brain. Brain tissue hemorrhage and mild vacuolation were also observed, suggesting that the high lethality of Delta-12 was associated with lung and brain pathology. Our long-term infection model can provide mutant viruses derived from SARS-CoV-2 Delta and knowledge about the possible contributions of emergent mutations to the properties of new variants.

Purpose: Our aim was to evaluate the effect of prophylactic pilocarpine on acute salivary symptoms after radioactive iodine (RAI) therapy in patients with differentiated thyroid cancer. Methods: We enrolled 88 patients (76 women and 12 men; mean age: 47 years; range: 20-74 years) with differentiated thyroid cancer who received RAI. Patients were divided into pilocarpine (51 patients) and control (37 patients) groups. Pilocarpine was given orally, at a dose of 5 mg three times a day, from 2 days before and 12 days after RAI therapy. Symptoms and signs of acute sialadenitis within 3 months of RAI therapy were recorded. Results: During the 3 months after RAI therapy, 13 of the 88 patients (14.7%) developed acute symptomatic sialadenitis (swelling or pain of salivary glands). Acute salivary symptoms were reported by 4 (7.8%) and 9 (24.3%) patients in the pilocarpine and control groups, respectively. Acute salivary symptoms were less frequent in the pilocarpine than control group (p = 0.04), but did not differ by age, sex, or RAI dose (p = 0.3357, p = 0.428, and p = 0.2792). Conclusions: Pilocarpine reduced the likelihood of acute sialadenitis after RAI therapy in patients with differentiated thyroid cancer.

INTRODUCTION: Cystometry is essential for evaluating bladder function. However, children may react negatively to the physical pain of urethral catheterization or anxiety and fear of an unfamiliar environment. These pain responses during the cystometry procedure may interfere with the cystometry procedure and make it difficult to interpret the cystometry result. In this regard, the International Children's Continence Society has advised performing cystometry while holding infants as an effective nonpharmacological pain management method, but there is insufficient evidence to support this. PURPOSE: This study aimed to analyze the effect of parental holding on reducing pain in children during cystometry. METHODS: This was an experimental study in a randomized controlled pre-post test design. A total of 64 participants aged 6-18 months were recruited. During cystometry, the participants in the experimental group were placed on the parent's laps and held in the parents' arms. The participants in the control group were laid down on the examination table. During the procedure, both groups of parents were allowed to touch their children in all ways except holding them and to use the pacifier if they wished. The behavioral (face, leg, activity, cry, consolability scale) and physiological (oxygen saturation and heart rate) pain responses were measured at three-time points (immediately, 3, and 10 min after urethral catheter insertion). RESULTS: Comparing the two groups, in the experimental group, the behavioral pain response at 3 min after urethral catheter insertion (t = -2.165, p = 0.034) and 10 min after (t = -3.155, p = 0.002) was decreased compared with that immediately after urethral catheter insertion. In addition, oxygen saturation increased more (t = 2.021, p = 0.048), and the heart rate decreased more (t = -2.033, p = 0.047) at 10 min than at 3 min after urethral catheter insertion in the experimental group. CONCLUSIONS: This study revealed that parental holding could reduce pain responses during cystometry in children. Further research is required to confirm the applicability and usefulness of parental holding during cystometry.

AIM: To explore digital health interventions on patient safety for children and their parents. DESIGN: A scoping review. METHODS: The PCC 'Participants, Concepts, and Contexts' guided the selection of studies that focused on children under 19 years of age or their parents, patient safety interventions for children, and digital health technology for patient safety interventions. This study was conducted using the Arksey and O'Malley framework's five steps. We reported the review according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews Checklist. DATA SOURCES: PubMed, CINAHL, Embase, Web of Science, and Cochrane were searched for articles published up to November 2022. RESULTS: A total of 13 articles were included and categorized according to the following criteria to describe the results: intervention characteristics, type of digital technology, and outcome characteristics. Regarding intervention characteristics, we identified two categories, prevention and risk management. Additionally, we identified four types of digital technology, mobile applications, web-based technologies, computer kiosks and electronic health records. Finally, in studies focussing on child safety, parental safety behaviours were used to assess injury risk or detect changes related to prevention. CONCLUSION: Patient safety interventions provided through appropriate digital technologies should be developed to enhance continuum of care for children from hospitalization to home after discharge. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Digital health interventions can bolster the role of healthcare providers in patient safety in and out of hospitals, thus improving children's safety and quality of care. IMPACT: What problem did the study address? Although the various advantages of digital health technology have been demonstrated, the potential role of digital technology in patient safety interventions for children has not been explored. What were the main finding? Preventive patient safety interventions and risk management for children have been developed. Where and on whom will the research have an impact? Digital health interventions on patient safety can improve children's safety and quality of care by promoting non-face-to-face engagement of children and parents after discharge and expanding healthcare providers' roles. TRIAL AND PROTOCOL REGISTRATION: Registered on the Open Science Framework (https://osf.io/dkvst). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

This study evaluated the prognostic significance of FDG PET/CT in patients with nodal peripheral T-cell lymphoma (PTCL). We retrospectively reviewed patients with histologically confirmed nodal PTCL who underwent FDG PET/CT at baseline, after three cycles of first-line chemotherapy (interim), and at the end of therapy. Response was assessed visually using the Deauville 5-point scale (D5PS); scores of 1, 2, and 3 were considered PET-negative, and scores of 4 and 5 were considered PET-positive. The associations between FDG PET/CT findings and survival were assessed using Cox regression analysis. A total of 79 patients (44 males and 35 females; median age 56 years) were included in this study. In response assessment, 17 (22%) had an interim PET-positive result and 10 (13%) had an end-of-therapy PET-positive result. During a median follow-up of 50 months, 37 patients (47%) presented with disease progression and 30 patients (38%) died. The estimated 5-year progression-free survival (PFS) and overall survival (OS) were 57% and 64%, respectively. An interim PET-positive result was the only significant indicator of PFS. Higher International Prognostic Index and end-of-therapy PET-positive result were significant independent prognostic factors of OS. Interim and end-of-therapy FDG PET/CT responses based on D5PS are meaningful in predicting the outcomes of patients with nodal PTCL.
RESUMO
The conversion of cellular prion protein (PrPC) into pathogenic prion isoforms (PrPSc) and the mutation of PRNP are definite causes of prion diseases. Unfortunately, without exception, prion diseases are untreatable and fatal neurodegenerative disorders; therefore, one area of research focuses on identifying medicines that can delay the progression of these diseases. According to the concept of drug repositioning, we investigated the efficacy of the c-Abl tyrosine kinase inhibitor radotinib, which is a drug that is approved for the treatment of chronic myeloid leukemia, in the treatment of disease progression in prion models, including prion-infected cell models, Tga20 and hamster cerebellar slice culture models, and 263K scrapie-infected hamster models. Radotinib inhibited PrPSc deposition in neuronal ZW13-2 cells that were infected with the 22L or 139A scrapie strains and in cerebellar slice cultures that were infected with the 22L or 263K scrapie strains. Interestingly, hamsters that were intraperitoneally injected with the 263K scrapie strain and intragastrically treated with radotinib (100 mg/kg) exhibited prolonged survival times (159 ± 28.6 days) compared to nontreated hamsters (135 ± 9.9 days) as well as reduced PrPSc deposition and ameliorated pathology. However, intraperitoneal injection of radotinib exerted a smaller effect on the survival rate of the hamsters. Additionally, we found that different concentrations of radotinib (60, 100, and 200 mg/kg) had similar effects on survival time, but this effect was not observed after treatment with a low dose (30 mg/kg) of radotinib. Interestingly, when radotinib was administered 4 or 8 weeks after prion inoculation, the treated hamsters survived longer than the vehicle-treated hamsters. Additionally, a pharmacokinetic assay revealed that radotinib effectively crossed the blood-brain barrier. Based on our findings, we suggest that radotinib is a new candidate anti-prion drug that could possibly be used to treat prion diseases and promote the remission of symptoms.

PURPOSE: The Quality of Life Assessment in Spina bifida for Teenagers (QUALAS-T) is a tool used to evaluate health-related quality of life (HRQOL) in adolescents with spina bifida (SB). The purpose of this study was to translate the QUALAS-T into Korean and validate its Korean version (QUALAS-T-K). METHODS: Translation and validation processes were carried out in accordance with a specified protocol, including forward and back translation, a content validity study, and a main study. The tool's reliability was evaluated based on its internal consistency and stability. Factor analysis was conducted, and convergent validity was confirmed using the KIDSCREEN-27. RESULTS: Of the 59 participants, 35 had lipomyelomeningoceles. Confirmatory factor analysis confirmed that QUALAS-T-K had the same structure as QUALAS-T. The QUALAS-T-K showed excellent internal consistency (α: 0.872-0.893, ω: 0.875-0.885), test-retest reliability (ICC:0.84-0.92), and weak to strong correlations with the KIDSCREEN-27. CONCLUSIONS: The QUALAS-T-K, developed by reflecting on the characteristics of SB and considering the applicability of Korean cultural characteristics and clinical practice, is a convenient and reliable tool with excellent internal consistency and stability. This could be a useful tool in clinical and research settings for HRQOL evaluation of adolescents with SB.Implications for RehabilitationOptimizing health-related quality of life (HRQOL) is one of the goals of individuals with spina bifida (SB), and HRQOL measures that reflect the condition specificity of SB should be performed.The QUAlity of Life Assessment in Spina bifida for Teenagers (QUALAS-T), developed in the USA, is a self-reported HRQOL questionnaire used in research and clinical practice for adolescents with SB.This study revealed that the QUALAS-T, translated into Korean, is a valid, convenient, and reliable tool.The Korean version of the QUALAS-T is a useful tool that can be used in clinical and research settings to optimize HRQOL in adolescents with SB.
RESUMO
BACKGROUND: Children with spina bifida (SB) may have congenital or acquired foot deformities due to neurological defects in the spinal cord. As the musculoskeletal system keeps growing, foot deformities can develop or become aggravated. Thus, healthcare providers should provide constant monitoring and proper orthopedic management. Since foot deformities can affect not only the gait but also the daily life of children with SB, it is necessary to investigate the impact of foot deformities on everyday life. The purpose of this study was to examine the relationship between foot deformity and health-related quality of life (HRQoL) among independently ambulating children with SB. METHODS: This cross-sectional study examined the associations between foot deformity and HRQoL using two patient-reported outcome measures (Oxford Ankle Foot Questionnaire, Pediatric Outcomes Data Collection Instrument) in 93 children with SB aged 7-18 years between January 2020 and July 2021. RESULTS: Children with foot deformity (n = 54) reported lower scores in all subscales (physical, school and play, emotional, and footwear) of the Oxford Ankle Foot Questionnaire for children than those without foot deformity (n = 39; p < 0.001). Additionally, in terms of the Pediatric Outcomes Data Collection Instrument, children with foot deformity also reported poorer scores in four subscales (transfer and basic mobility, sports and physical functioning, comfort and pain, happiness with physical functioning; p < 0.001) than those without foot deformity, whereas upper extremity functioning was not significantly affected. Children with foot deformities, particularly those with bilateral foot deformities, equinus deformities, or mixed deformities, which are different types of right and left foot deformities, have a lower perceived HRQoL (p < 0.05). CONCLUSIONS: Among independently ambulating children with SB, those with foot deformities showed lower HRQoL. Moreover, children with foot deformities tend to have other clinical problems, including bladder and bowel dysfunction. Therefore, orthopedic management should consider the multifaceted factors that affect children's daily life and HRQoL.

AIM: Analysis of the concept of hypertension literacy to ensure clarity, reduce ambiguities and promote consistency in usage. DESIGN: Walker and Avant's concept analysis method was adopted. METHODS: Searched four electronic databases using keywords combined with the appropriate Boolean operators. After removing duplicates, thirty titles were identified, and ten articles met the basic criteria for inclusion. The analysis was done using a convergent synthesis design to integrate results and transform them into qualitative descriptions. RESULTS: Hypertension literacy's defining attributes were hypertension information search skills, comprehension of numeracy associated with blood pressure and medication and utilization of hypertension prevention information. The identified antecedents were formal education and improved cognitive, social, economic and health-related experiences. Consequences of hypertension literacy included improved self-reported and increased health awareness. Hypertension literacy allows nurses to assess and accurately improve knowledge and facilitate people to adopt prevention behaviours.

PURPOSE: This study aimed to translate and cross-culturally adapt the QUAlity of Life Assessment in Spina bifida for Children (QUALAS-C) and validate the Korean version of the QUALAS-C (QUALAS-C-K). MATERIALS AND METHODS: Three urologists translated the QUALAS-C into Korean. Facial and content validity were assessed in the pilot study. Back-translation into English was performed. In the main study, the QUALAS-C-K and Korean version of KIDSCREEN-27 were administered simultaneously. Test-retest reliability was confirmed by re-administering the QUALAS-C-K. Internal consistency was verified using Cronbach's alpha. Factor analysis was performed, and convergent and divergent validity were demonstrated using the Korean version of KIDSCREEN-27. RESULTS: A total of 53 children with spina bifida participated in the main study. Cronbach's alpha for the overall instrument determined good internal consistency (0.72-0.85), the intraclass correlation coefficient showed good stability (0.74-0.77), and the factor analysis converged to the same two-factor structure as in the original version. Construct validity revealed weak-to-moderate associations (r ≤ 0.57) between QUALAS-C-K and K-KIDSCREEN-27, indicating that QUALAS-C-K measures different aspects of the HRQOL than K-KIDSCEEN-27. CONCLUSIONS: The QUALAS-C-K is a reliable and valid instrument for assessing the health-related quality of life of children with SB in Korea.IMPLICATIONS FOR REHABILITATIONHealth-related quality of life (HRQOL) is an important patient-reported outcome among children with spina bifida (SB).The QUAlity of Life Assessment of Spina bifida for Children (QUALAS-C) is a self-reported, age-appropriate, and condition-specific HRQOL questionnaire for children with SB, developed in the United States.Our study demonstrated that the Korean version of the QUAlity of Life Assessment of Spina bifida for Children (QUALAS-C-K) is a valid and reliable tool.The QUALAS-C-K is a succinct and valuable questionnaire that can be used to assess HRQOL of children with SB, particularly focusing on bladder and bowel problems in clinical practice and research.
RESUMO
PURPOSE: The diagnosis of cancer in children can negatively impact their parents, owing to the complex treatment processes. Families with high levels of resilience can overcome these difficulties and thus perform higher family functions. We aimed to develop an internet-based family resilience-promoting program for parents of children with cancer and evaluate its effect on the levels of family resilience, depression, and family function. METHODS: This prospective, parallel-group, randomized-controlled study that was conducted at Yonsei Cancer Center from June to October 2021 included 41 parents of children with cancer. In total, four sessions of the internet-based family resilience-promoting program, led by a nurse, were conducted individually for parents. Levels of family resilience, depression, and family function were measured before, immediately after, and 4 weeks after the program. The data were analyzed using the linear mixed-effect model, and program satisfaction was evaluated through an internet-based questionnaire and interview. RESULTS: The experimental group (the family resilience-promoting program participants) differed more significantly from the control group in the level of change in family resilience (ß = 13.214, p = 0.003, effect size = 0.374) and family function (ß = 1.256, p = 0.018, effect size = 0.394). However, there was no significant difference between the groups in the level of depression (ß = 2.133, p = 0.187, effect size = 0.416). All the program participants showed a high program satisfaction score of 4.75 out of 5.00 points overall. CONCLUSIONS: The applicability of the internet-based family resilience-promoting program as an appropriate nursing intervention was verified. Its application can help the families of children with cancer adapt to the stressful situation of their children's cancer diagnosis and treatment.

BACKGROUND: Recently, nurse continuity, the intensity and consistency of a patient's exposure to nurses during hospitalization, has been shown to be associated with patient outcomes. However, little is known about how nurse continuity is related to patients' surgical outcomes. AIMS: To examine the association between nurse continuity and outcomes of hypospadias repair to clarify the importance of nurse continuity as a nursing practice. DESIGN: This is a retrospective study. METHODS: We analysed the data from electronic health records of patients under 1 year who had undergone proximal hypospadias repair between January 2014 and December 2016. Nurse continuity was measured using the Continuity of Care Index. Since approximately half of the patients reportedly needed further operations in the long term, the primary outcome was whether patients with proximal hypospadias repair had two or more additional operations within 3 years of discharge. RESULTS: The rate of undergoing two or more follow-up operations in 3 years was significantly higher in patients with low nurse continuity-38.6% versus 12.8% for high continuity. CONCLUSION: This study identified nurse continuity as an important factor related to patients' surgical outcomes. These findings suggest that nurse continuity be considered an important nursing strategy for patient outcomes and further research is needed on this topic. IMPACT STATEMENT: As empirical evidence regarding the association between nurse continuity and patient outcomes grows, nurse managers and policymakers should view nurse continuity as a critical factor for positive patient outcomes when considering nursing workforce regulations. NO PATIENT OR PUBLIC CONTRIBUTION: The data for this study were obtained from electronic health records, and the entire process of this study did not involve patient or public participation.

Prions are infectious protein particles known to cause prion diseases. The biochemical entity of the pathogen is the misfolded prion protein (PrPSc) that forms insoluble amyloids to impair brain function. PrPSc interacts with the non-pathogenic, cellular prion protein (PrPC) and facilitates conversion into a nascent misfolded isoform. Several small molecules have been reported to inhibit the aggregation of PrPSc but no pharmacological intervention was well established thus far. We, here, report that acylthiosemicarbazides inhibit the prion aggregation. Compounds 7x and 7y showed almost perfect inhibition (EC50 = 5 µM) in prion aggregation formation assay. The activity was further confirmed by atomic force microscopy, semi-denaturing detergent agarose gel electrophoresis and real-time quaking induced conversion assay (EC50 = 0.9 and 2.8 µM, respectively). These compounds also disaggregated pre-existing aggregates in vitro and one of them decreased the level of PrPSc in cultured cells with permanent prion infection, suggesting their potential as a treatment platform. In conclusion, hydroxy-2-naphthoylthiosemicarbazides can be an excellent scaffold for the discovery of anti-prion therapeutics.

Hepatic encephalopathy (HE) is one of the main complications of liver cirrhosis (LC) and is classified into minimal hepatic encephalopathy (MHE) and overt hepatic encephalopathy (overt HE). S100B is expressed mainly in astrocytes and other glial cells, and S100B has been reported to be associated with various neurological disorders. The present study aimed to investigate the diagnostic ability of serum S100B to discriminate the grade of HE and the parameters correlated with serum S100B levels. Additionally, we investigated whether serum S100B levels can be used to predict 1-year mortality in cirrhotic patients. In total, 95 cirrhotic patients were consecutively enrolled and divided into the following three groups: (i) without any types of HEs; (ii) with MHE; and (iii) with overt HE. The diagnosis of MHE was made by the Mini-Mental State Examination (MMSE) and Psychometric Hepatic Encephalopathy Score (PHES). Among the three groups, there were no significant differences in serum S100B levels regardless of HE severity. The clinical parameters correlated with serum S100B levels were age, serum bilirubin, and creatinine levels. The Model for End-Stage Liver Disease (MELD) score showed a significant positive correlation with serum S100B levels. The relationship between serum S100B levels and MELD score was maintained in 48 patients without any type of HE. Additionally, hyperammonemia, low cholesterol levels, and the combination of serum S100B levels ≥ 35 pg/mL with MELD score ≥ 13 were factors for predicting 1- year mortality. In conclusion, serum S100B level was not useful for differentiating the severity of HE. However, we found that serum S100B levels can be affected by age, serum bilirubin, and creatinine in cirrhotic patients and are associated with MELD scores. Additionally, serum S100B levels showed the possibility of predicting 1-year mortality in cirrhotic patients. These findings suggest that serum S100B levels may reflect liver dysfunction and prognosis in liver disease.
RESUMO
Furanocoumarin 8-methoxypsoralen (8-MOP) is the parent compound that naturally occurs in traditional medicinal plants used historically. 8-MOP has been employed as a photochemotherapeutic component of Psoralen + Ultraviolet A (PUVA) therapy for the treatment of vitiligo and psoriasis. Although the role of 8-MOP in PUVA therapy has been studied, little is known about the effects of 8-MOP alone on human gastric cancer cells. In this study, we observed anti-proliferative effect of 8-MOP in several human cancer cell lines. Among these, the human gastric cancer cell line SNU1 is the most sensitive to 8-MOP. 8-MOP treated SNU1 cells showed G1-arrest by upregulating p53 and apoptosis by activating caspase-3 in a dose-dependent manner, which was confirmed by loss-of-function analysis through the knockdown of p53-siRNA and inhibition of apoptosis by Z-VAD-FMK. Moreover, 8-MOPinduced apoptosis is not associated with autophagy or necrosis. The signaling pathway responsible for the effect of 8-MOP on SNU1 cells was confirmed to be related to phosphorylated PI3K, ERK2, and STAT3. In contrast, 8-MOP treatment decreased the expression of the typical metastasis-related proteins MMP-2, MMP-9, and Snail in a p53-independent manner. In accordance with the serendipitous findings, treatment with 8-MOP decreased the wound healing, migration, and invasion ability of cells in a dose-dependent manner. In addition, combination treatment with 8-MOP and gemcitabine was effective at the lowest concentrations. Overall, our findings indicate that oral 8-MOP has the potential to treat early human gastric cancer, with fewer side effects.
