RESUMEN
PURPOSE: Although mobile-based symptom monitoring is expected to improve patient participation in symptom management during anticancer therapy, previous trials have not evaluated its effectiveness. Therefore, this study aims to evaluate the impact of a symptom monitoring mobile application on improving patient participation in symptom management during anticancer therapy. METHODS: We conducted a single-center, open-label, randomized controlled trial that enrolled patients with breast, lung, head and neck, esophageal, or gynecologic cancer who were scheduled to receive anticancer therapy (oral or intravenous) between October 2020 and March 2021. We excluded patients with physical or psychological problems. The intervention group received a symptom monitoring application for 8 weeks, and the control group received the usual clinical practice. At 8 weeks, the improvement in patient participation in symptom management was assessed, and additionally quality of life and unplanned clinical visits were assessed. RESULTS: A total of 222 patients were included in the analysis, of whom 142 were randomly assigned to the intervention group and 71 to the control group. The intervention group reported better outcome in patient participation in symptom management than the control group at 8 weeks (mean scores of 8.5 vs. 8.0; P = 0.01). There were no significant differences between the groups in Quality of life (P = 0.88) and unplanned clinical visits (P = 0.39-0.76). CONCLUSIONS: This study is meaningful in figuring out that the mobile-based symptom monitoring made them more engaged in their management. Future research should continue to evaluate the effects of patient participation as mediators of clinical outcomes. TRIAL REGISTRATION: ClinicalTrials.gov NCT04568278.

PURPOSE: This study aims to identify factors associated with the adoption and compliance of electronic patient-reported outcome measure (ePROM) use among cancer patients in a real-world setting. METHODS: This prospective cohort study was conducted at the Samsung Medical Center in Seoul, Korea, from September 2018 to January 2019. Cancer patients aged 18 years or older who owned smartphones and who were receiving chemotherapy or radiation therapy were eligible for this study. Patients were asked to use the app to report their symptoms every 7 days for a total of 21 days (3 weeks). Logistic regression was performed to identify the factors associated with the adoption and compliance. RESULTS: Among 580 patients, 417 (71.9%) adopted the ePROM app and 159 (27.4%) out of 417 had good compliance. Patients who had greater expectations regarding the ease of use (adjusted odds ratio [aOR] 2.67, 95% CI: 1.28-5.57) and usefulness (aOR 1.69, 95% CI: 1.05-2.72) of the ePROM app were more likely to adopt the app than those who did not. Patients who had greater satisfaction with usefulness (aOR 1.89, 95% CI 1.10-3.25) were more likely to comply with using the app, but satisfaction with ease of use was not related to the compliance. CONCLUSION: While expectation regarding the ease of use and usefulness of the ePROM app was associated with the adoption of the app, satisfaction with ease of use was not related to compliance with the ePROM app. Satisfaction with usefulness was associated with the compliance of ePROM app use.

BACKGROUND: The purpose of the study was to translate and linguistically validate a Korean language version of the PROMIS (K-PROMIS) for the six profile adult domains: Fatigue, Pain Intensity, Pain Interference, Physical Function, Sleep Disturbance, and Ability to Participate in Social Roles and Activities. METHODS: A total of 268 items were translated into Korean according to the Functional Assessment of Chronic Illness Therapy multilingual translation methodology. Participants first completed approximately 27 to 35 items and were then interviewed to evaluate the conceptual equivalence of the translation to the original English language source. The K-PROMIS items that met the a priori threshold of ≥ 20% of respondents with comprehension difficulties in the cognitive interview. RESULTS: 54 of the 268 items were identified as difficult items to comprehend for at least 20% of respondents in Round 1. The most frequently identified K-PROMIS domain on difficult items to comprehend was the Physical function (24.5%). Most items with linguistic difficulties were Fatigue and Physical function. Cultural difficulties were only included the Physical function and Ability to Participate in Social Roles and Activities domains. 25 of 54 items were slightly revised, and then these revised items were tested with additional six participants in Round 2, and most participants had no problems to understand modified items. CONCLUSION: The six profile adult domains of K-PROMIS have been linguistically validated. Further psychometric validation of the K-PROMIS items will provide additional information of meaningful outcomes for chronic disease and clinical setting.

BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome, is associated with gastroesophageal reflux disease in cross-sectional studies, but a prospective association has not been evaluated. The current study aimed to determine whether NAFLD increases the risk of incident reflux esophagitis in a large cohort study. METHODS: We conducted a cohort study of 34 063 men and women without reflux esophagitis or other upper gastrointestinal disease at baseline who underwent health checkup examinations between January 2003 and December 2013. Fatty liver was diagnosed by ultrasound based on standard criteria. Reflux esophagitis was defined by the presence of at least grade A mucosal break on esophagogastroduodenoscopy. RESULTS: The prevalence of NAFLD at baseline was 33.2%. During 153 520.2 person-years of follow-up, the cumulative incidences of reflux esophagitis for participants without and with NAFLD were 9.6% and 13.8%, respectively (P < 0.001). The age-adjusted and sex-adjusted hazard ratio for the risk of reflux esophagitis development in participants with NAFLD compared with those without NAFLD was 1.15 (95% confidence interval 1.07-1.23; P < 0.001). However, this association disappeared after adjusting for body mass index and other metabolic factors (hazard ratio 1.01, 95% confidence interval 0.94-1.09; P = 0.79). Similarly, in multivariable-adjusted models, there was no significant association between NAFLD severity and the risk of developing reflux esophagitis. CONCLUSIONS: Non-alcoholic fatty liver disease is not independently associated with the risk of the development of reflux esophagitis, but rather, reflux esophagitis is primarily the consequence of increased body mass index commonly associated with NAFLD.

Sacbrood virus (SBV) represents a serious threat to the health of managed honeybees. We determined four complete SBV genomic sequences (AmSBV-Kor1, AmSBV-Kor2, AcSBV-Kor3, and AcSBV-Kor4) isolated from Apis mellifera and Apis cerana in various regions of South Korea. A phylogenetic tree was constructed from the complete genomic sequences of these Korean SBVs (KSBVs) and 21 previously reported SBV sequences from other countries. Three KSBVs (not AmSBV-Kor1) clustered with previously reported Korean genomes, but separately from SBV genomes from other countries. The KSBVs shared 90-98 % identity, and 89-97 % identity with the genomes from other countries. AmSBV-Kor1 was least similar (~90 % identity) to the other KSBVs, and was most similar to previously reported strains AmSBV-Kor21 (97 %) and AmSBV-UK (93 %). Phylogenetic analysis of the partial VP1 region sequences indicated that SBVs clustered by host species and country of origin. The KSBVs were aligned with nine previously reported complete SBV genomes and compared. The KSBVs were most different from the other genomes at the end of the 5' untranslated region and in the entire open reading frame. A SimPlot graph of the VP1 region confirmed its high variability, especially between the SBVs infecting A. mellifera and A. cerana. In this genomic region, SBVs from A. mellifera species contain an extra continuous 51-nucleotide sequence relative to the SBVs from A. cerana. This genomic diversity may reflect the adaptation of SBV to specific hosts, viral cross-infections, and the spatial distances separating the KSBVs from other SBVs.

Proteomic tools allow large-scale, high-throughput analyses for the detection, identification, and functional investigation of proteome. For detection of antigens from Haemaphysalis longicornis, 1-dimensional electrophoresis (1-DE) quantitative immunoblotting technique combined with 2-dimensional electrophoresis (2-DE) immunoblotting was used for whole body proteins from unfed and partially fed female ticks. Reactivity bands and 2-DE immunoblotting were performed following 2-DE electrophoresis to identify protein spots. The proteome of the partially fed female had a larger number of lower molecular weight proteins than that of the unfed female tick. The total number of detected spots was 818 for unfed and 670 for partially fed female ticks. The 2-DE immunoblotting identified 10 antigenic spots from unfed females and 8 antigenic spots from partially fed females. Matrix Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF) of relevant spots identified calreticulin, putative secreted WC salivary protein, and a conserved hypothetical protein from the National Center for Biotechnology Information and Swiss Prot protein sequence databases. These findings indicate that most of the whole body components of these ticks are non-immunogenic. The data reported here will provide guidance in the identification of antigenic proteins to prevent infestation and diseases transmitted by H. longicornis.

Acarapis mites, including Acarapis woodi, Acarapis externus, and Acarapis dorsalis, are parasites of bees which can cause severe damage to the bee industry by destroying colonies and decreasing honey production. All 3 species are prevalent throughout many countries including UK, USA, Iran, Turkey, China, and Japan. Based on previous reports of Acarapis mites occurring in northeast Asia, including China and Japan, we investigated a survey of Acarapis mite infestations in honey bees in Korean apiaries. A total of 99 colonies of Apis mellifera were sampled from 5 provinces. The head and thorax of 20 bees from each colony were removed for DNA extraction. PCR assays were performed with 3 primer sets, including T, A, and K primers. Results indicated that 42.4% (42/99) of samples were Acarapis-positive by PCR assay which were sequenced to identify species. Each sequence showed 92.6-99.3% homology with reference sequences. Based on the homology, the number of colonies infected with A. dorsalis was 32 which showed the highest infection rate among the 3 species, while the number of colonies infected with A. externus and A. woodi was 9 and 1, respectively. However, none of the Acarapis mites were morphologically detected. This result could be explained that all apiaries in the survey used acaricides against bee mites such as Varroa destructor and Tropilaelaps clareae which also affect against Acarapis mites. Based on this study, it is highly probable that Acarapis mites as well as Varroa and Tropilaelaps could be prevalent in Korean apiaries.

Kashmir bee virus (KBV) is one of the most common viral infections in honeybees. In this study, a phylogenetic analysis was performed using nine partial nucleotide sequences of RdRp and the structural polyprotein regions of South Korean KBV genotypes, as well as nine previously reported KBV genotypes from various countries and two closely related genotypes of Israeli acute paralysis virus (IAPV) and Acute bee paralysis virus (ABPV). The Korean KBV genotypes were highly conserved with 94-99 % shared identity, but they also shared 88-95 % identity with genotypes from various countries, and they formed a separate KBV cluster in the phylogenetic tree. The complete genome sequence of Korean KBV was also determined and aligned with previously reported complete reference genome sequences of KBV, IAPV, and ABPV to compare different genomic regions. The complete Korean KBV genome shared 93, 79, and 71 % similarity with the complete reference genomes of KBV, IAPV, and ABPV, respectively. The Korean KBV was highly conserved relative to the reference KBV genomes in the intergenic and 3' untranslated region (UTR), but it had a highly variable 5' UTR, whereas there was little divergence in the helicase and 3C-protease of the nonstructural protein, and the external domains of the structural polyprotein region. Thus, genetic recombination and geographical distance may explain the genomic variations between the Korean and reference KBV genotypes.

This study reports the first case of Capillaria hepatica infection in a nutria in Korea. Ten nutrias, captured near the Nakdong River, were submitted to our laboratory for necropsy. White-yellowish nodules were found in the liver of 1 of the nutrias at necropsy. Histologically, the lesions were granulomatous, and infiltrations of lipid-laden macrophages, eosinophils, and several multinucleated giant cells were observed. The lesions consisted of numerous eggs and necrotic hepatocytes. The eggs were lemon-shaped and had polar plugs at the ends of both long sides. The eggs were morphologically identified as those of C. hepatica. Worldwide, C. hepatica infection in nutrias is very rare. Nutrias are a kind of livestock, as well as wildlife; therefore, an epidemiological study for parasitic infections needs to be conducted.

OBJECTIVE: To evaluate a psychometric validation of the endometrial cancer subscales (EnCS) in the Functional Assessment of Cancer Therapy-Endometrial (FACT-EN) among patients with endometrial cancer. METHODS: This cross-sectional study was conducted at a tertiary university-based hospital in South Korea between April and October 2022. Participants completed a survey questionnaire that included the FACT-EN. Exploratory and confirmatory factor analyses (EFA, CFA) and the reliability were measured using the intraclass correlation coefficient (ICC) under a two-way mixed model. Pearson's correlations were used to evaluate the validity. We also tested known-group validity. RESULTS: In total, 240 patients with endometrial cancer participated in the survey. In EFA, we found EnCS included four domains. In CFA, four-factor solution model was good: CFI = 0.659; SRMR = 0.066, and RMSEA = 0.073. The mean (SD) of total score of FACT-EN was 122.84 (23.58). The floor and ceiling effects were 0.4% and 0.4%, respectively. Cronbach's α coefficients for the five scales of the EnCS ranged from 0.78 to 0.91. The ICC of EnCS was 0.76. The convergent and discriminant validity of EnCS was acceptable. In the group analysis, older age and lower ECOG performance scores were associated with higher EnCS scores. The stomach and vaginal domains in EnCS were higher in patients who had completed treatment for more than 1 year compared to those who were still undergoing treatment. CONCLUSIONS: FACT-EN has demonstrated its validity as an assessment tool with significant implications for capturing various symptoms in patients with endometrial cancer.

OBJECTIVE: Although breast magnetic resonance imaging (MRI) is a valuable screening tool, breast MRI testing burden was associated with cancer worry and quality of life. We aimed to develop and validate the MRI-related distress scale (MRI-DS) to assess comprehensive distress specifically related to breast MRI. METHODS: We enrolled women aged above 18 years, diagnosed breast cancer, had MRI examination at least one time, and who could speak and read Korean in phase I and enrolled women aged above 18 years, visited outpatient clinic of breast general surgery, had undergone MRI examination at least once, and could speak and read Korean in phase II. We excluded patients who had any physical or psychiatric conditions in both phases. We recruited from a tertiary university-based hospital in South Korea between April and August 2023. RESULTS: All 18 items had acceptable levels of item correlation (≥0.30) in the explanatory factor analysis with a four-factor solution. The fit indices for the four-factor solution model were good. The discriminant validity of the MRI-DS had a moderate correlation with general anxiety or quality of life. In the known-group analysis, those who reported MRI as the most burden breast examination had higher total scores. CONCLUSION: The validity of the MRI-DS has been confirmed as a scale for measuring the specific distress caused by breast MRI. The MRI-DS is recommended to health professional to communicate with patients with MRI. CLINICAL IMPLICATIONS: It can be used to assess the distress associated with MRI screening in breast cancer patients. Physician could use MRI-DS to discuss the reasons for distress caused by breast MRI screening and to address specific sources of discomfort associated with it.

Objective: This study focuses on identifying potential complications following oblique lumbar interbody fusion (OLIF) through routine magnetic resonance (MR) scans. Methods: From 650 patients who underwent OLIF from April 2018 to April 2022, this study included those with MR scans taken one-week post-operatively, and only for indirect decompression patients. The analysis evaluated postoperative MR images for hematoma, cage insertion angles, and indirect decompression efficiency. Patient demographics, post-operatively symptoms, and complications were also evaluated. Results: Out of 401 patients enrolled, most underwent 1- or 2-level OLIF. Common findings included approach site hematoma (65.3%) and contralateral psoas hematoma (19%). The caudal level OLIF was related with less orthogonality and deep insertion of cage. Incomplete indirect decompression occurred in 4.66% of cases but did not require additional surgery. Rare but symptomatic complications included remnant disc rupture (4 cases, 1%) and synovial cyst rupture (4 cases, 1%). Conclusion: This study has identified potential complications associated with OLIF, including approach site hematoma, contralateral psoas hematoma, cage malposition risk at caudal levels, and radiologically insufficient indirect decompression. Additionally, it highlights rare, yet symptomatic complications such as remnant disc rupture and synovial cyst rupture. These findings contribute insights into the relatively under-explored area of OLIF complications.
RESUMEN
Glycogen synthase kinase-3 (GSK-3) is emerging as a prominent therapeutic target of Alzheimer's disease (AD). A number of studies have been undertaken to develop GSK-3 inhibitors for clinical use. We report two novel GSK-3 inhibitors (C-7a and C-7b) showing good activity and pharmacokinetic (PK) profiles. IC50 of new GSK-3 inhibitors were in the range of 120-130 nM, and they effectively reduced the Aß-oligomers induced neuronal toxicity. Also, new GSK-3 inhibitors decreased the phosphorylated tau at pThr231, pSer396, pThr181, and pSer202, and inhibited the GSK-3 activity against Aß-oligomers induced neuronal cell toxicity. In B6;129-Psen1(tm1Mpm) Tg(APPSwe, tauP301L)1Lfa/Mmjax model of AD, oral administration of C-7a (20 mg/kg, 50 mg/kg) showed increased total arm entries and spontaneous alteration of Y-maze which was regarded as short-term memory. In particular, 50 mg/kg C-7a treated mice significantly decreased the level of phosphorylated tau (Ser396) in brain hippocampus. We suggest that new GSK-3 inhibitor (C-7a) is potential candidates for the treatment of AD.

MicroRNAs are important regulators of developmental gene expression, but their contribution to fetal gonad development is not well understood. We have identified the evolutionarily conserved gonadal microRNAs miR-202-5p and miR-202-3p as having a potential role in regulating mouse embryonic gonad differentiation. These microRNAs are expressed in a sexually dimorphic pattern as the primordial XY gonad differentiates into a testis, with strong expression in Sertoli cells. In vivo, ectopic expression of pri-miR-202 in XX gonads did not result in molecular changes to the ovarian determination pathway. Expression of the primary transcript of miR-202-5p/3p remained low in XY gonads in a conditional Sox9-null mouse model, suggesting that pri-miR-202 transcription is downstream of SOX9, a transcription factor that is both necessary and sufficient for male sex determination. We identified the pri-miR-202 promoter that is sufficient to drive expression in XY but not XX fetal gonads ex vivo. Mutation of SOX9 and SF1 binding sites reduced ex vivo transactivation of the pri-miR-202 promoter, demonstrating that pri-miR-202 may be a direct transcriptional target of SOX9/SF1 during testis differentiation. Our findings indicate that expression of the conserved gonad microRNA, miR-202-5p/3p, is downstream of the testis-determining factor SOX9, suggesting an early role in testis development.

Necrotizing sialometaplasia of the parotid gland is infrequent and can be mistaken as a malignant disease. Its etiology is thought to be an insufficient blood supply. Bilateral involvement of this disease in parotid glands has been rarely reported in the English literature. We report a case of necrotizing sialometaplasia diagnosed after superficial parotidectomy due to bilateral parotid masses in a 69-year old heavy smoking female.

RIP1 (receptor-interacting protein kinase 1) is an important component of TNF-α signaling that contributes to various pathological effects. Here, we revealed new potential roles of RIP1 in controlling WNT/ß-catenin canonical signaling to enhance metastasis of colorectal cancer (CRC). First, we showed that WNT3A treatment sequentially increased the expression of RIP1 and ß-catenin. Immunohistochemical analyses of human CRC tissue arrays consisting of normal, primary, and metastatic cancers indicated that elevated RIP1 expression might be related to ß-catenin expression, carcinogenesis, and metastasis. Intravenous injection of RIP1 over-expressed CRC cells into mice has demonstrated that RIP1 may promote metastasis. Immunoprecipitation (IP) results indicated that WNT3A treatment induces direct binding between RIP1 and ß-catenin, and that this stabilizes the ß-catenin protein in a manner that depends on the regulation of RIP1 ubiquitination via downregulation of the E3 ligase, cIAP1/2. Elimination of cIAP1/2 expression and inhibition of its ubiquitinase activity enhance WNT3A-induced RIP1 and ß-catenin protein expression and binding, which stimulates endothelial-mesenchymal transition (EMT) induction to enhance the migration and invasion of CRC cells in vitro. The results of the in vitro binding assay and IP of exogenous RIP1-containing CRC cells additionally verified the direct binding of RIP1 and ß-catenin. RIP1 expression can destroy the ß-catenin-ß-TrCP complex. Taken together, these results suggest a novel EMT-enhancing role of RIP1 in the WNT pathway and suggest a new canonical WNT3A-RIP1-ß-catenin pathway that contributes to CRC malignancy by promoting EMT.

BACKGROUND: Symptom monitoring application (SMA) has clinical benefits to cancer patients but patients experience difficulties in using it. Few studies have identified which types of graphical user interface (GUI) are preferred by cancer patients for using the SMA. METHODS: This is a cross-sectional study aimed to identify preferred GUI among cancer patients to use SMA. Total of 199 patients were asked to evaluate 8 types of GUIs combining text, icon, illustration, and colors using mixed-methods. Subgroup analyses were performed according to age and gender. RESULTS: The mean age of the patients was 57 and 42.5% was male. The most preferred GUI was "Text + Icon + Color" (mean = 4.43), followed by "Text + Icon" (mean = 4.39). Older patients (≥ 60 years) preferred "Text + Icon" than younger patients (p for interaction < 0.01). Simple and intuitive text and icons were the most useful GUI for cancer patients to use the SMA. CONCLUSION: Simple and intuitive text and icons were the most useful GUI for cancer patients to use the SMA. Researchers need to be careful when applying realistic face drawings to cancer symptom monitoring applications because they can recall negative images of cancer.

INTRODUCTION: Glucose monitoring-related problems affect the social and psychological distress experienced by patients with diabetes, and this distress leads to low compliance. Consequently, it is important to be able to comprehensively assess distress due to glucose monitoring in these patients. We have developed and validated a distress of self-glucose monitoring (DSGM) scale instrument to assess patient distress from glucose monitoring. METHODS: Following an extensive literature review and qualitative study, we selected 21 items for assessing the DSGM, including physical, psychosocial, and process domains. We conducted a cross-sectional study in patients with insulin-treated diabetes aged 10-40 years at Samsung Medical Center, Seoul, Korea, from April 2021 to September 2021. Exploratory and confirmatory factor analyses (CFA) were performed to confirm the structural validity of the DSGM scale. To confirm construct and criterion validity, we assumed that the Korean version of the Problem Areas in Diabetes (PAID-K) instrument, life interference, and stress due to glucose monitoring might moderately correlate with the total score and scores of all domains of the DSGM scale except for the physical domain. RESULTS: Cronbach's alpha coefficients for the DSGM scale were 0.92, and Cronbach's alpha coefficients of the three subscales ranged from 0.69 to 0.92, indicating satisfactory internal consistency. The DSGM scale was evaluated using CFA, and the fit indices for this model were good. The PAID-K total score, life interference, and stress due to glucose monitoring were moderately correlated with the total score of the DSGM scale and with the scores of the psychosocial and process domains, and were weakly correlated with the score of the physical domain of the DSGM scale. CONCLUSION: The DSGM scale is a valid and reliable tool to evaluate distress due to glucose monitoring in adults, adolescents, and children with diabetes.
RESUMEN
Insulin injections are stressful but necessary for people with diabetes. This study aimed to develop and validate the Distress of Self-Injection (DSI) scale for patients with diabetes aged ≥ 10 years. We created a questionnaire to evaluate DSI after examining each item following a literature review. The DSI scale with 20 questions in three domains (physical [4], psychosocial [7], and process [9]) was developed and tested at the Samsung Medical Center in Seoul, Korea, from April to September 2021. To verify structural validity, exploratory and confirmatory factor analyses (CFA) were conducted. Internal consistency was also calculated. To assess construct and criterion validity, the correlation between the DSI scale and Korean version of the Problem Areas in Diabetes (PAID-K) scale was obtained. Cronbach's alpha varied from 0.69 to 0.87, and the DSI score was 0.90, demonstrating acceptable internal consistency. CFA fit indices (CFI = 0.980; RMSEA = 0.033) were favorable. DSI and pertinent PAID-K domains correlated strongly. For measuring self-injection distress, the DSI score had good accuracy. For patients with diabetes aged ≥ 10 years who self-inject insulin, the DSI was a viable and accurate method for quantifying discomfort associated with insulin injection. Health practitioners should use the DSI to communicate with patients about their suffering.
