To investigate disparities in sensitisation to Staphylococcus aureus enterotoxin A/B (SEA/SEB) and olfactory function in patients with chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), those with CRS without nasal polyps (CRSsNP), and healthy controls who underwent septoplasty only. We retrospectively reviewed the medical records of 388 subjects agedā€‰ā‰„ā€‰8 years, collected between January 2021 and June 2023. We analysed patient demographics, medical history, serum IgE levels against staphylococcal enterotoxins (SEs), and serum total IgE levels against inhalant allergens.

Background: Calprotectin is an antimicrobial peptide primarily secreted by neutrophils. Furthermore, calprotectin secretion increases in patients with chronic rhinosinusitis (CRS) with polyps (CRSwNP) and positively correlates with neutrophil markers. However, CRSwNP is known to be associated with type 2 inflammation related to tissue eosinophilia.

Heart rate variability (HRV) has been suggested to reflect executive function and related neural activity. Executive dysfunction has been suggested to play an important role in the pathophysiology of emotional disorders. The purpose of this study was to investigate whether HRV showed a significant correlation with electroencephalogram (EEG) during a working memory performance in patients with depressive or anxiety disorder.

Division of Child and Adolescent Psychiatry, Department of Psychiatry, Severance Hospital, Institute of Behavioral Science in Medicine, Yonsei University College of Medicine, Seoul, South Korea. Electronic address:

Children with neurodevelopmental disorders, such as attention deficit hyperactivity disorder (ADHD) and intellectual disability (ID), need early intervention and continuous treatment. We aimed to investigate the feasibility and acceptability of mobile application-based interventions in children with ADHD and ID in supporting attention and cognitive function. Twenty-six children with ADHD and/or ID with attention and cognition difficulties were recruited.

Objectives: Several allergy tests are used for the diagnosis of allergic rhinitis; however, few studies have reported a direct comparison of the skin prick test (SPT), multiple allergen simultaneous test (MAST), and ImmunoCAP according to specific allergens. This study aimed to evaluate the correlations between each test and allergic rhinitis symptoms and to evaluate the correlations of the MAST and ImmunoCAP with the SPT for representative indoor allergens in Korea.

Methods: Electronic medical charts were retrospectively reviewed, and 698 patients with allergic rhinitis who had performed SPT, MAST, and ImmunoCAP were enrolled.

Background: Metabolic disorders are established precursors to cardiovascular diseases, yet they can be readily prevented with sustained lifestyle modifications.

Objective: We assessed the effectiveness of a smartphone-based weight management app on metabolic parameters in adults at high-risk, yet without physician diagnosis nor pharmacological treatment for metabolic syndrome, in a community setting.

Methods: In this 3-arm parallel-group, single-blind, randomized controlled trial, we recruited participants aged 30 to 59 years with at least 2 conditions defined by the Third Report of the National Cholesterol Education Program expert panel (abdominal obesity, high blood pressure, high triglycerides, low high-density lipoprotein cholesterol, and high fasting glucose level).

Background: We investigated the clinical course of patients with prolonged disorders of consciousness (PDoC), predictors of emergence from PDoC (EDoC), and the temporal dynamics of six neurobehavior domains based on the JFK Coma Recovery Scale-Revised (CRS-R) during the recovery.

Methods: A total of 50 traumatic and non-traumatic patients with PDoC were enrolled between October 2014 and February 2017. A retrospective analysis of the clinical findings and neurobehavioral signs was conducted using standardized methodology such as CRS-R.

Purpose: Subfertility associated with polycystic ovary syndrome (PCOS) mainly originates from oligoovulation/anovulation. Although insulin resistance and androgen excess are known to cause PCOS-associated implantation failure, the consequences of PCOS on endometrial homeostasis and pathophysiology have not been comprehensively understood. In this study, we examined whether the pathophysiologic milieu of PCOS intrinsically affects expression profiles of genes related to insulin signaling and facilitative glucose transporters (GLUTs) in the human endometrium and/or during in vitro decidualization.

Comparison of olfactory and taste functions between eosinophilic and non-eosinophilic chronic rhinosinusitis.

Auris Nasus Larynx

October 2020

Department of Otorhinolaryngology, Yonsei University College of Medicine, Republic of Korea; The Airway Mucus Institute, Yonsei University College of Medicine, Seoul, Republic of Korea. Electronic address:

Objective: Most patients with chronic rhinosinusitis (CRS) complain of olfactory and/or taste dysfunctions. However, olfactory and taste dysfunctions depending on the subtype of CRS, classified as eosinophilic CRS (ECRS) and non-eosinophilic CRS (NCRS), have not been clearly reported. Therefore, the purpose of this study was to investigate the clinical features in olfactory and taste functions according to the subtype classified as ECRS and NCRS.

Background: Hypertrophic cardiomyopathy (HCM) is a multigenic disease that occurs due to various genetic modifiers. We investigated phenotype-based clinical and genetic characteristics of HCM patients using comprehensive genetic tests and rare variant association analysis.

Methods: A comprehensive HCM-specific panel, consisting of 82 nuclear DNAs (nDNAs: 33 sarcomere-associated genes, 5 phenocopy genes, and 44 nuclear genes linked to mitochondrial cardiomyopathy) and 37 mitochondrial DNAs (mtDNAs), was analyzed.

Severance Institute for Vascular and Metabolic Research, Yonsei University College of Medicine, Seoul, Republic of Korea. Electronic address:

Aims: Baicalin, a flavonoid glycoside substance extracted from Scutellaria baicalensis Georgi, has been shown to exhibit multiple therapeutic properties owing to its anti-inflammatory effect. Diabetes is characterized by chronic hyperglycemia, inflammation and oxidative stress, which promote renal fibrosis and kidney failure. Although anti-fibrogenic effects of baicalin in lung and liver have been reported previously, no study has investigated its roles in renal fibrosis.

Objective: By combining data from the Clinical Research Center for Dementia of South Korea(CREDOS) study and long-term care insurance(LTCI), we aimed to assess whether the severity of white matter hyperintensity(WMH) predicted functional decline in cases of amnestic mild cognitive impairment(MCI).

Methods: WMH was evaluated in 3,569 patients with amnestic MCI using the visual rating scale developed for the CREDOS study. The participants were classified as having amnestic MCI with minimal WMH change(aMCI), with moderate WMH change(maMCI) and with severe WMH change(saMCI) according to the severity of the WMH measurements.

Recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) has been a longstanding challenge for head and neck oncologists, and current treatments still have limited efficacy. ERK is aberrantly overexpressed and activated in HNSCC. Herein, we aimed to investigate the cause of the limited therapeutic effect of selumetinib, a selective inhibitor of MEK in HNSCC, as MEK/ERK reactivation inevitably occurs.

Herbal Medicines for Cold Hypersensitivity in the Hands and Feet: A Systematic Review and Meta-Analysis.

J Altern Complement Med

December 2018

Department of Preventive Medicine, Wonju College of Medicine, Yonsei University, Wonju, Republic of Korea.

Cold hypersensitivity in the hands and feet (CHHF) and Raynaud's phenomenon (RP) are prevalent among Asian populations, especially among women, who exhibit a higher rate of cold hypersensitivity that may be associated with gynecological problems. In several countries, herbal medicine has effectively treated cold hypersensitivity symptoms. This systematic review and meta-analysis of the literature was undertaken to evaluate the efficacy of herbal medicine for the treatment of CHHF in adults.
