Inflammatory Endotypes of Chronic Rhinosinusitis in the Korean Population: Distinct Expression of Type 3 Inflammation. ALLERGY, ASTHMA & IMMUNOLOGY RESEARCH 2023; 15:437-450. [PMID: 37075796 PMCID: PMC10359642 DOI: 10.4168/aair.2023.15.4.437] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Revised: 11/28/2022] [Accepted: 12/13/2022] [Indexed: 07/21/2023]
Abstract
PURPOSE Cluster analyses on inflammatory markers of chronic rhinosinusitis (CRS) in Asians from multicenter data are lacking. This multicenter study aimed to identify the endotypes of CRS in Koreans and to evaluate the relationship between the endotypes and clinical parameters. METHODS Nasal tissues were obtained from patients with CRS and controls who underwent surgery. The endotypes of CRS were investigated by measuring interleukin (IL)-5, interferon (IFN)-γ, IL-17A, IL-22, IL-1β, IL-6, IL-8, matrix metalloproteinase-9, eotaxin-3, eosinophil cationic protein, myeloperoxidase (MPO), human neutrophil elastase (HNE), periostin, transforming growth factor-β1, total immunoglobulin E (IgE), and staphylococcal enterotoxin (SE)-specific IgE. We performed hierarchical cluster analysis and evaluated the phenotype, comorbidities, and Lund-Mackay computed tomography (LM CT) score in each cluster. RESULTS Five clusters and 3 endotypes were extracted from 244 CRS patients: cluster 1 had no upregulated mediators compared to the other clusters (mild mixed inflammatory CRS); clusters 2, 3, and 4 had higher concentrations of neutrophil-associated mediators including HNE, IL-8, IL-17A, and MPO (T3 CRS); and cluster 5 had higher levels of eosinophil-associated mediators (T2 CRS). SE-specific IgE was undetectable in T3 CRS and had low detectable levels (6.2%) even in T2 CRS. The CRS with nasal polyps (CRSwNP) phenotype and LM CT scores showed no significant differences between T2 and T3 CRS, while the incidence of comorbid asthma was higher in T2 CRS than T3 CRS. In T3 clusters, higher levels of neutrophilic markers were associated with disease severity and CRSwNP phenotype. CONCLUSIONS In Koreans, there is a distinct T3 CRS endotype showing a high proportion of CRSwNP and severe disease extent, along with T2 CRS.

Abstract
Background Megakaryocytes (MKs) are platelet precursors, which arise from hematopoietic stem cells (HSCs). While MK lineage commitment and differentiation are accompanied by changes in gene expression, many factors that modulate megakaryopoiesis remain to be uncovered. Replication origin binding protein (RepID) which has multiple histone-code reader including bromodomain, cryptic Tudor domain and WD40 domains and Cullin 4-RING ubiquitin ligase complex (CRL4) recruited to chromatin mediated by RepID have potential roles in gene expression changes via epigenetic regulations. We aimed to investigate whether RepID-CRL4 participates in transcriptional changes required for MK differentiation. Methods The PCR array was performed using cDNAs derived from RepID-proficient or RepID-deficient K562 erythroleukemia cell lines. Correlation between RepID and DAB2 expression was examined in the Cancer Cell Line Encyclopedia (CCLE) through the CellMinerCDB portal. The acceleration of MK differentiation in RepID-deficient K562 cells was determined by estimating cell sizes as well as counting multinucleated cells known as MK phenotypes, and by qRT-PCR analysis to validate transcripts of MK markers using phorbol 12-myristate 13-acetate (PMA)-mediated MK differentiation condition. Interaction between CRL4 and histone methylation modifying enzymes were investigated using BioGRID database, immunoprecipitation and proximity ligation assay. Alterations of expression and chromatin binding affinities of RepID, CRL4 and histone methylation modifying enzymes were investigated using subcellular fractionation followed by immunoblotting. RepID-CRL4-JARID1A-based epigenetic changes on DAB2 promoter were analyzed by chromatin-immunoprecipitation and qPCR analysis. Results RepID-deficient K562 cells highly expressing MK markers showed accelerated MKs differentiation exhibiting increases in cell size, lobulated nuclei together with reaching maximum levels of MK marker expression earlier than RepID-proficient K562 cells. Recovery of WD40 domain-containing RepID constructs in RepID-deficient background repressed DAB2 expression. CRL4A formed complex with histone H3K4 demethylase JARID1A in soluble nucleus and loaded to the DAB2 promoter in a RepID-dependent manner during proliferation condition. RepID, CRL4A, and JARID1A were dissociated from the chromatin during MK differentiation, leading to euchromatinization of the DAB2 promoter. Conclusion This study uncovered a role for the RepID-CRL4A-JARID1A pathway in the regulation of gene expression for MK differentiation, which can form the basis for the new therapeutic approaches to induce platelet production.

Concomitant Use of Antiplatelet Agents and Proton-Pump Inhibitors Increases the Risk of Adverse Cardiovascular Events: A Nationwide Population-Based Cohort Study Using Balanced Operational Definitions. J Cardiovasc Dev Dis 2023; 10:264. [PMID: 37367429 DOI: 10.3390/jcdd10060264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 06/02/2023] [Accepted: 06/16/2023] [Indexed: 06/28/2023] Open
Abstract
Antiplatelet agents are commonly used in combination with proton-pump inhibitors (PPIs) in patients with acute coronary syndrome who are at risk of gastrointestinal hemorrhage. However, studies have reported that PPIs can alter the pharmacokinetics of antiplatelet agents and result in adverse cardiovascular events. We enrolled 311 patients who received antiplatelet therapy with PPIs for >30 days and 1244 matched controls following a 1:4 propensity score matching during the index period. Patients were followed up until death, myocardial infarction, coronary revascularization, or the end of the follow-up period. Patients who used antiplatelet therapy with PPIs were found to be at higher risk of mortality than the controls (adjusted hazard ratio (HR): 1.77; 95% confidence interval (CI): 1.30-2.40). The adjusted HR for patients who used antiplatelet agents with PPIs developing myocardial infarction and coronary revascularization events was 3.52 (95% CI: 1.34-9.22) and 4.74 (95% CI: 2.03-11.05), respectively. Additionally, middle-aged patients or those within 3 years of concomitant use showed a higher risk of myocardial infarction and coronary revascularization. Our findings suggest that antiplatelet therapy combined with PPIs has a higher mortality risk in patients with gastrointestinal bleeding and is associated with an increased risk of myocardial infarction and coronary revascularization.

Abstract
BACKGROUND Spontaneous intracranial hypotension is an important cause of treatable secondary headaches. Evidence on the efficacy of epidural blood patching and surgery for spontaneous intracranial hypotension has not been synthesized. PURPOSE Our aim was to identify evidence clusters and knowledge gaps in the efficacy of treatments for spontaneous intracranial hypotension to prioritize future research. DATA SOURCES We searched published English language articles on MEDLINE (Ovid), the Web of Science (Clarivate), and EMBASE (Elsevier) from inception until October 29, 2021. STUDY SELECTION We reviewed experimental, observational, and systematic review studies assessing the efficacy of epidural blood patching or surgery in spontaneous intracranial hypotension. DATA ANALYSIS One author performed data extraction, and a second verified it. Disagreements were resolved by consensus or adjudicated by a third author. DATA SYNTHESIS One hundred thirty-nine studies were included (median, 14 participants; range, 3-298 participants). Most articles were published in the past decade. Most assessed epidural blood patching outcomes. No studies met level 1 evidence. Most were retrospective cohort or case series (92.1%, n = 128). A few compared the efficacy of different treatments (10.8%, n = 15). Most used objective methods for the diagnosis of spontaneous intracranial hypotension (62.3%, n = 86); however, 37.7% (n = 52) did not clearly meet the International Classification of Headache Disorders-3 criteria. CSF leak type was unclear in 77.7% (n = 108). Nearly all reported patient symptoms using unvalidated measures (84.9%, n = 118). Outcomes were rarely collected at uniform prespecified time points. LIMITATIONS The investigation did not include transvenous embolization of CSF-to-venous fistulas. CONCLUSIONS Evidence gaps demonstrate a need for prospective study designs, clinical trials, and comparative studies. We recommend using the International Classification of Headache Disorders-3 diagnostic criteria, explicit reporting of CSF leak subtype, inclusion of key procedural details, and using objective validated outcome measures collected at uniform time points.

The clue is in the kidneys: greater renal contrast medium accumulation on ipsilateral side down CT myelogram after lateral decubitus digital subtraction myelogram as a predictor of laterality of cerebrospinal fluid leak. Clin Radiol 2023:S0009-9260(23)00173-3. [PMID: 37225571 DOI: 10.1016/j.crad.2023.04.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 03/31/2023] [Accepted: 04/23/2023] [Indexed: 05/26/2023]
Abstract
AIM To assess the potential correlation of the laterality of a cerebrospinal fluid (CSF)-venous fistula with the laterality of decubitus computed tomography (CT) myelogram (post decubitus digital subtraction myelogram) based on which side demonstrated more renal contrast medium excretion. MATERIALS AND METHODS Patients with CSF-venous fistulas diagnosed at lateral decubitus digital subtraction myelograms were reviewed retrospectively. Patients who did not have CT myelogram following one or both left and right lateral decubitus digital subtraction myelograms were excluded. Two neuroradiologists independently interpreted the CT myelogram for the presence or absence of renal contrast, and whether subjectively more renal contrast medium was visualised on the left or right lateral decubitus CT myelogram. RESULTS Renal contrast medium was seen in lateral decubitus CT myelograms in 28 of 30 (93.3%) patients with CSF-venous fistulas. Having more renal contrast medium in right lateral decubitus CT myelogram was 73.9% sensitive and 71.4% specific for the diagnosis of a right-sided CSF-venous fistula, whereas having more renal contrast medium in the left lateral decubitus CT myelogram was 71.4% sensitive and 82.6% specific for a left-sided CSF-venous fistula (p=0.02). CONCLUSION When the CSF-venous fistula lies on the dependent side of a decubitus CT myelogram performed after decubitus digital subtraction myelogram, relatively more renal contrast medium is visualised compared to when the fistula lies on the non-dependent side.

Abstract
BACKGROUND AND PURPOSE Wrong-level spinal surgery, especially in the thoracic spine, remains a challenge for a variety of reasons related to visualization, such as osteopenia, large body habitus, severe kyphosis, radiographic misinterpretation, or anatomic variation. Preoperative fiducial marker placement performed in a dedicated imaging suite has been proposed to facilitate identification of thoracic spine vertebral levels. In this current study, we report our experience using image-guided percutaneous gold fiducial marker placement to enhance the accuracy and safety of thoracic spinal surgical procedures. MATERIALS AND METHODS A retrospective review was performed of all fluoroscopy- or CT-guided gold fiducial markers placed at our institution between January 3, 2019, and March 16, 2022. A chart review of 179 patients was performed detailing the procedural approach and clinical information. In addition, the method of gold fiducial marker placement (fluoroscopy/CT), procedure duration, spinal level of the gold fiducial marker, radiation dose, fluoroscopy time, surgery date, and complications (including whether wrong-level surgery occurred) were recorded. RESULTS A total of 179 patients (104 female) underwent gold fiducial marker placement. The mean age was 57 years (range, 12-96 years). Fiducial marker placement was performed by 13 different neuroradiologists. All placements were technically successful without complications. All 179 (100%) operations were performed at the correct level. Most fiducial markers (143) were placed with fluoroscopy with the most common location at T6-T8. The most common location for placement in CT was at T3 and T4. CONCLUSIONS All operations guided with gold fiducial markers were performed at the correct level. There were no complications of fiducial marker placement.

Abstract
In this study, carbon nanotubes (CNTs) were grown under the same conditions as those of carbon fibers and glass fibers, and a comparative analysis was performed to confirm the potential of glass fibers with grown CNTs as electromagnetic interference (EMI) shielding materials. The CNTs were grown directly on the two fiber surfaces by a chemical vapor deposition process, with the aid of Ni particles loaded on them via a Ni-P plating process followed by heat treatment. The morphology and structural characteristics of the carbon and glass fibers with grown CNTs were analyzed using scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), X-ray diffraction (XRD), and X-ray photoelectron spectrometry (XPS), and the EMI shielding efficiency (EMI SE) of the directly grown CNT/carbon and glass fiber-reinforced epoxy matrix composites was determined using a vector-network analyzer. As the plating time increased, a plating layer serving as a catalyst formed on the fiber surface, confirming the growth of numerous nanowire-shaped CNTs. The average EMI SET values of the carbon fiber-reinforced plastic (CFRP) and glass fiber-reinforced plastic (GFRP) with grown CNTs maximized at approximately 81 and 40 dB, respectively. Carbon fibers with grown CNTs exhibited a significantly higher EMI SET value than the glass fiber-based sample, but the latter showed a higher EMI SET increase rate. This indicates that low-cost, high-quality EMI-shielding materials can be developed through the growth of CNTs on the surface of glass fibers.

Abstract
Endometriosis is a multifactorial disease, and inflammation is considered a core pathology. Inflammation related to genital tract infection (GTI) and surgical injury may cause endometriosis. Therefore, we investigated the incidence of endometriosis in women with a recent history of GTI, pelvic surgery, or both. Using the Korean National Health Insurance Service-National Sample Cohort, 20- to 49-year-old women diagnosed with GTI or who underwent pelvic surgeries between 2002 and 2008 were collected and followed up for five years. After excluding women who had already been diagnosed with endometriosis or diseases that may affect endometriosis, a total of 30,336 women were diagnosed with GTI (Study 1), 2894 women who underwent pelvic surgery (Study 2), and 788 women who underwent GTI and pelvic surgery, both (Study 3) were enrolled for each study. The comparison groups in which sociodemographic factors matched for each group were collected. The incidence of endometriosis per 1000 person-year was 5.37, 5.17, and 20.81 in each case group and was significantly higher than each comparison group. A recent history of GTI increased an adjusted hazard ratio (aHR) of 2.29 (1.99-2.63, 95% confidence interval) for the development of endometriosis. The aHRs of pelvic surgery history and the history of both GTI and pelvic surgery were 2.10 and 7.82, respectively. In conclusion, the pelvic inflammation resulting from genital infection and pelvic surgical injury may play a role in developing endometriosis. Active treatment of genital infections and careful surgical procedures to minimize tissue injury may reduce the incidence of pelvic endometriosis.

Abstract
Allergic rhinitis is the most common chronic disease worldwide. Various upper airway symptoms lower quality of life, and due to the recurrent symptoms, multiple treatments are usually attempted rather than one definitive treatment. There are alternatives to medical (medication-based) and non-medical treatments. A guideline is needed to understand allergic rhinitis and develop an appropriate treatment plan. We have developed guidelines for medical treatment based on previous reports. The current guidelines herein are associated with the "KAAACI Evidence-Based Guidelines for Allergic Rhinitis in Korea, Part 1: Update in pharmacotherapy" in which we aimed to provide evidence-based recommendations for the medical treatment of allergic rhinitis. Part 2 focuses on non-pharmacological management, including allergen-specific immunotherapy, subcutaneous or sublingual immunotherapy, nasal saline irrigation, environmental management strategies, companion animal management, and nasal turbinate surgery. The evidence to support the treatment efficacy, safety, and selection has been systematically reviewed. However, larger controlled studies are needed to elevate the level of evidence to select rational non-medical therapeutic options for patients with allergic rhinitis.

Abstract
Burning mouth syndrome (BMS) is a chronic, painful condition of the oral mucosa. Although the pathogenesis remains unclear, psychological and neuroendocrine factors are considered the major contributors. Few longitudinal studies have investigated the effects of psychological factors on the occurrence of BMS. Therefore, we evaluated the risk of BMS in patients with affective disorders using a nationwide population-based cohort dataset. We identified patients with depression, anxiety, and bipolar disorder and then selected comparison participants using the 1:4 propensity score-matching method. We investigated the incidence of BMS events during the follow-up period using survival analysis, the log-rank test, and Cox proportional hazards regression models. After adjusting for other contributing conditions, the adjusted hazard ratio (HR) for developing BMS was 3.37 (95% confidence interval [CI]: 1.67-6.80) for depression and 5.09 (95% CI: 2.19-11.80) for anxiety; however, bipolar disorder showed no significant risk. Specifically, female patients with depression and anxiety had an increased risk of BMS. Moreover, patients with anxiety showed an increased adjusted HR of BMS events during the first 4 years after diagnosis, whereas patients with depression did not. In conclusion, depression and anxiety disorders are significantly associated with the risk of BMS. Additionally, female patients showed a significantly higher risk of BMS than male patients, and anxiety showed increased BMS events earlier than depression. Therefore, clinicians should consider the risk of BMS when treating patients with depression or anxiety.

Abstract
This retrospective nationwide population-based cohort study used a dataset collected from the Korean National Health Insurance Service. We evaluated incident type 2 diabetes, insulin requirements, and diabetes-associated complications during a 10-year follow-up period using the log-rank test and Cox proportional hazards regression models. In total, 8114 and 16,228 individuals with and without cancer, respectively, were enrolled. We found a higher incidence rate and an increased adjusted hazard ratio (HR) for new cases of type 2 diabetes in patients with cancer, compared with those without cancer. Additionally, patients with cancer had a higher risk of insulin requirement than patients without cancer (adjusted HR 1.43, 95% confidence interval [CI], 1.14-1.78). Although there was no significant association between diabetes-associated complications and overall cancer diagnosis, specific cancer types (pancreas, bladder, and prostate) showed an increased risk of subsequent diabetic nephropathy. Therefore, clinicians should closely monitor patients with cancer for the early detection of type 2 diabetes and related morbidities.

Abstract
Introduction Much drug development and published analysis for epithelial ovarian cancer (EOC) focuses on early-line treatment. Full sequences of treatment from diagnosis to death and the impact of later lines of therapy are rarely studied. We describe the establishment of an international network of cancer centers configured to compare real-world treatment pathways in UK, Portugal, Germany, South Korea, France and Romania (the Ovarian Real-World International Consortium; ORWIC). Methods 3344 patients diagnosed with EOC (2012-2018) were analysed using a common data model and hub and spoke programming approach applied to existing electronic medical records. Consistent definition of line of therapy between sites and an efficient approach to analysis within the limitations of local information governance was achieved. Results Median age of participants was 53-67 years old and 5-29% were ECOG >1. Between 62% and 84% of patients were diagnosed with late-stage disease (FIGO III-IV). Sites treating younger and fitter patients had higher rates of debulking surgery for those diagnosed at late stage than sites with older, more frail patients. At least 21% of patients treated with systemic anti-cancer therapy (SACT) had recurrent disease following second-line therapy (2L); up to 11 lines of SACT treatment were recorded for some patients. Platinum-based SACT was consistently used across sites at 1L, but choices at 2L varied, with hormone therapies commonly used in the UK and Portugal. The use (and type) of maintenance therapy following 1L also varied. Beyond 2L, there was little consensus between sites on treatment choice: trial compounds and unspecified combinations of other agents were common. Discussion Specific treatment sequences are reported up to 4L and the establishment of this network facilitates future analysis of comparative outcomes per line of treatment with the aim of optimizing available options for patients with recurrent EOC. In particular, this real-world network can be used to assess the growing use of PARP inhibitors. The real-world optimization of advanced line treatment will be especially important for patients not usually eligible for involvement with clinical trials. The resources to enable this analysis to be implemented elsewhere are supplied and the network will seek to grow in coverage of further sites.

Abstract
This study aimed to investigate the possible link between glaucoma and dementia using a nationwide cohort sample of data. The glaucoma group (n = 875) included patients diagnosed between 2003 and 2005, aged over 55 years; the comparison group was selected using propensity score matching (n = 3500). The incidence of all-cause dementia was 18.67 (7014.7 person-years) among those with glaucoma aged over 55 years. The glaucoma group developed all-cause dementia more frequently than those in the comparison group (adjusted hazard ratio (HR) = 1.43, 95% confidence interval (CI), 1.17-1.74). In a subgroup analysis, primary open-angle glaucoma (POAG) showed a significantly increased adjusted HR for all-cause dementia events (1.52, 95% CI: 1.23-1.89), whereas we could not find any significant association in patients with primary angle-closure glaucoma (PACG). Additionally, POAG patients showed an increased risk of the development of Alzheimer's disease (adjusted HR = 1.57, 95% CI, 1.21-2.04) and Parkinson's disease (adjusted HR = 2.29, 95% CI, 1.46-3.61), but there was no significant difference in PACG patients. Moreover, the risk of Alzheimer's disease and Parkinson's disease was higher within 2 years of POAG diagnosis. Although our findings have some limitations, such as confounding factor bias, we suggest that clinicians should pay attention to the early detection of dementia in patients with POAG.

Abstract
The prevalence of allergic rhinitis (AR) and the socioeconomic burden associated with the medical cost and quality of life (QOL) of AR have progressively increased. Therefore, practical guidelines for the appropriate management of AR need to be developed based on scientific evidence while considering the real-world environment, values, and preferences of patients and physicians. The Korean Academy of Asthma, Allergy and Clinical Immunology revised clinical guidelines of AR to address key clinical questions of the management of AR. Part 1 of the revised guideline covers the pharmacological management of patients with AR in Korea. Through a meta-analysis and systematic review, we made 4 recommendations for AR pharmacotherapy, including intranasal corticosteroid (INCS)/intranasal antihistamine (INAH) combination therapy, oral antihistamine/INCS combination therapy, leukotriene receptor antagonist treatment in AR patients with asthma, and prophylactic treatment for patients with pollen-induced AR. However, all recommendations are conditional because of the low or very low evidence of certainty. Well-designed and strictly executed randomized controlled trials are needed to measure and report appropriate outcomes.

Abstract
PURPOSE This study aimed to demonstrate the necessary walking skills for community ambulation of individuals with chronic stroke using a validated community ambulation survey. METHODS A total of 107 older adults and 99 ambulatory, urban-living people with chronic stroke were sampled by convenience method. A community ambulation survey was developed to establish content and concurrent validity. Using the survey, older adults and individuals with stroke documented the frequency with which walking tasks were performed throughout the day. RESULTS The survey was valid for clinical use (kappa coefficients ranging from 0.737 to 0.873). Compared with those encountered by the older adult group, walking tasks less frequently performed by the stroke group included the use of revolving doors, navigating stairs, walking through crossways, carrying and manipulating objects, and walking at a fast pace and for long distances. Participants in the stroke group used automatic doors to enter buildings and walked through underpasses to pass crossways more frequently than those in the older adult group. CONCLUSIONS These findings identify the walking tasks that people with chronic stroke show less participation in community, which should be involved in routine rehabilitation schedules to restore functional walking in the community.Implications for rehabilitationCommunity ambulation survey is appropriate to identify the challenging walking tasks that people with chronic stroke show less participation in community.People with chronic stroke showed less frequent participation in walking tasks such as using stairs, using crossways, carrying objects, and walking fast and long distances, which are challenging for them.To achieve the final goal of stroke rehabilitation, it is necessary to repeatedly practice challenging walking tasks in a routine rehabilitation schedule.

Abstract
Importance Turbinate surgery is an effective treatment for allergic rhinitis (AR) refractory to medical treatment. However, the long-term outcomes of turbinate surgery are still unclear and have not yet been confirmed by a meta-analysis and systematic review of the literature. Objective To investigate the long-term outcomes and safety of turbinate surgery in AR by performing a meta-analysis. Data Sources MEDLINE, Embase, the Cochrane Library, and ClinicalTrials.gov were searched through April 2021. Study Selection Studies that analyzed turbinate surgery alone, had a follow-up period of more than 1 year, examined long-term efficacy of turbinate surgery, used current turbinate surgery methods, and were published in a peer-reviewed journal were included. Full-text reviews were performed by 2 independent reviewers. Conflicts were resolved by a third reviewer. Data Extraction and Synthesis Descriptive and quantitative data were extracted; weighted mean difference (WMD) was synthesized under a random-effects model. Heterogeneity was assessed using the Q statistic and the I2 metric. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. Main Outcomes and Measures The long-term outcomes of turbinate surgery on subjective nasal symptoms and objective parameters. Results Of the 3962 citations retrieved, 18 studies comprising 1411 patients were included. Findings showed significantly decreased symptom scores in nasal obstruction (WMD, 4.60, 95% CI, 3.43-5.76), rhinorrhea (WMD, 3.12; 95% CI, 1.97-4.28), sneezing (WMD, 2.64; 95% CI, 1.74-3.54), itching (WMD, 1.75; 95% CI, 1.20-2.30), and nasal resistance (WMD, 0.16; 95% CI, 0.08-0.24) and a significant increased total nasal volume (WMD, 0.96; 95% CI, 0.73-1.19). There was no significant difference in the occurrence of any complication. More than 1 year after surgery, the improvements in nasal obstruction (WMD, 5.18; 95% CI, 3.00-7.37), rhinorrhea (WMD, 3.57; 95% CI, 1.78-5.37), and sneezing (WMD, 2.95; 95% CI, 1.58-4.32) were maintained. Conclusions and Relevance In this systematic review and meta-analysis, turbinate surgery was associated with positive outcomes in AR and maintained the association during long-term follow-up. The rate of complications is also low. These findings can guide the preoperative counseling of patients with AR being considered for turbinate surgery.

Yu H, Kim DK. Neutrophils Play an Important Role in the Recurrence of Chronic Rhinosinusitis with Nasal Polyps. Biomedicines 2022; 10:biomedicines10112911.

Abstract
Despite the heterogeneity of chronic rhinosinusitis (CRS), a clear link exists between type 2 immunity and the severity of CRS with nasal polyps (CRSwNP). However, recent studies have demonstrated that patients with severe type 2 CRSwNP also display abundant neutrophilic inflammation. Therefore, we investigated the factors associated with the recurrence of CRSwNP following sinus surgery using a machine-learning algorithm. We collected the demographics, clinical variables, and inflammatory profiles of 210 patients with CRSwNP who underwent sinus surgery. After one year, we evaluated whether each patient showed recurrence. Machine-learning methods, such as decision trees, random forests, and support vector machine models, have been used to predict the recurrence of CRSwNP. The results indicated that neutrophil inflammation, such as tissue and serum neutrophils, is an important factor affecting the recurrence of surgical CRSwNP. Specifically, the random forest model showed the highest accuracy in detecting recurrence among the three machine-learning methods, which revealed tissue neutrophilia to be the most important variable in determining surgical outcomes. Therefore, our machine-learning approach suggests that neutrophilic inflammation is increased in patients with difficult-to-treat CRSwNP, and the increased presence of neutrophils in subepithelial regions is closely related to poor surgical outcomes in patients with CRSwNP.

Abstract
Simple Summary Previous cohort studies using national claim data in Korea have shown conflicting results about the association between the use of proton pump inhibitors (PPIs) and the risk of gastric cancer. In this population-based cohort analysis using balanced operational definitions, proton pump inhibitor use was not associated with an increased risk of gastric cancer (Hazard ratio: 1.30, 95% confidence interval: 0.75–2.27). Previous cohort studies with an inappropriate operational definition for the inclusion criteria of the study subjects or index dates could be the reason of conflicting results. Abstract Objectives: Previous cohort studies using national claim data in Korea have shown conflicting results about the association between the use of proton pump inhibitors (PPIs) and the risk of gastric cancer. This may be due to differences in the inclusion criteria or index dates of each study. This study aims to evaluate the association between PPI use and the risk of gastric cancer using balanced operational definitions. Design: A population-based cohort analysis was conducted using the Korean National Health Insurance Service database. Subjects who used PPIs or histamine-2 receptor antagonist (H2RA) for more than 60 days after Helicobacter pylori eradication were included. The study subjects were those who had never used H2RAs (PPI users) and controls were those who had never used PPIs (H2RA users). For comparison, the index dates of previous studies were adopted and analyzed. The subjects were followed until the development of gastric cancer, death, or study end. Results: A total of 10,012 subjects were included after propensity score matching. During a median follow-up of 6.56 years, PPI was not associated with an increased risk of gastric cancer (Hazard ratio: 1.30, 95% confidence interval: 0.75–2.27). This was consistent if the cumulative daily dose was adjusted (90/120/180 days), or if the index date was changed to the first day of PPI prescription or the last day of Helicobacter pylori eradication. There was no significant difference in mortality between both groups. Conclusion: PPI use was not associated with an increased risk of gastric cancer.

Abstract
As a marketing strategy to stimulate consumers' spending desires, limitededition products are now being sold through raffles. Using data obtained from 365 consumers who had previously purchased sports shoes, the results revealed differences between consumers who had participated in
raffles and those who had not in terms of their purchase experience, propensity toward conspicuous consumption, and intention to repurchase. Propensity toward both purchases made for entertainment and impulsive purchasing were statistically higher in the group who had participated in raffles.
Regarding conspicuous consumption propensity, the group who had participated in raffles showed a stronger tendency to buy famous brands, seek others' recognition, and pursue fashion trends. Although the difference in postpurchase intention between the two groups was not statistically significant,
those who had participated in raffles showed stronger repurchase intentions. The results indicate that the sales method for limited-edition products can affect the purchase propensity of consumers and their postpurchase behavior.

Abstract
Abstract
Background
p.Arg4810Lys variant of the ring finger protein 213 (RNF213) vasculopathy is a nonsyndromatic vasculopathy involving multisystemic organs including pulmonary arteries. Peripheral pulmonary arterial stenosis (PPAS) with diffuse stenosis and beaded appearance is a unique feature of this disease and no treatment option has been tried before.
Methods
We performed BPA for PPAS in RNF213 patients (n=7). Severity of pulmonary hypertension was assessed by echocardiography and right heart catheterization at the baseline. Several clinical and hemodynamic parameters were followed up after each BPA sessions.
Results
All of the patients had dyspnea on exertion. Right ventricular dysfunction was observed in six patients and NT-proBNP was elevated (949.2±1148.1 pg/mL). Baseline echocardiography showed severe pulmonary hypertension (70.1±19.2 mmHg). Pulmonary arterial ballooning was performed to all patients, but stenting (n=6) and cutting balloon (n=1) was necessary due to elastic recoil. Improvement of clinical and hemodynamic parameters was achieved in six patients after 5.3 sessions of BPA in average. Reperfusion edema was seen in four patients, eventually leading to death in one patient.
Conclusions
Pulmonary arterial angioplasty, when coupled with stenting, is an effective treatment for PPAS with RNF213 vasculopathy. Although reperfusion injury was common and fatal in a few cases, it is the only modality to improve the patient's symptom and hemodynamics till now. Careful selection of the target population should be preceded to perform the intervention.

Abstract
In recent years, individual drivers' crash risk assessments have received much attention for identifying high-risk drivers. To this end, we propose a probabilistic assessment method of crash risks with a reproducible long-term dataset (i.e., traffic violations, license, and crash records). In developing this method, we used 7.75 million violations and crashes of 5.5 million individual drivers in Seoul, South Korea, from June 2013 to June 2017 (four years). The stochastic process of the Bayesian network (BN), whose structure is optimized by tabu-search, successfully evaluates individual drivers' crash and violation probability. In addition, the cluster analysis classifies drivers into five distinctive groups according to their estimated violation and crash probabilities. As a result, this study found that the estimated average crash rate within a cluster converges with the actual crash rate by the proposed framework without privacy issues. We also confirm that violation records and expected crash probability are strongly correlated, and there is a direct relationship between a driver's previous violations and crash record and the future at-fault crash. The proposed assessment method is valuable in developing proactive driver education programs and safety countermeasures, including adjusting the penalty system and developing user-based insurance by recognizing dangerous drivers and identifying their properties.
