Hyaluronic acid-based minocycline-loaded dissolving microneedle: Innovation in local minocycline delivery for periodontitis.

Periodontitis is a prevalent inflammatory disease that affects tooth-supporting tissues and is induced by complex polymicrobial dental plaques. Prior treatments, including topical antibiotic ointments, have faced difficulties in tissue permeability issues. Although dissolving microneedle (DMN) has been proposed as a painless and highly efficient transdermal drug delivery system to resolve this challenge, minocycline, widely used for the treatment of periodontitis, is light-sensitive, making it challenging to maintain its stability using conventional fabrication methods.

The development of the Cough Hypersensitivity Questionnaire for chronic cough.

Introduction: Chronic cough is considered a disorder of neuronal hypersensitivity in which patients frequently report abnormal laryngeal and chest sensations, and excessive triggers. To facilitate clinical assessment, we developed the Cough Hypersensitivity Questionnaire (CHQ).

Methods: Candidate questionnaire items were developed following interviews with patients with refractory chronic cough (n=10, United Kingdom), and review by a multidisciplinary team.

Exploring Traits Associated With Central Sensitization Features in Patients With Chronic Cough.

The concept of cough hypersensitivity suggests that central sensitization plays a role in the pathophysiology of chronic cough. However, it remains unclear which traits are associated with central sensitization features in patients with chronic cough. A cohort of 317 Korean patients with newly referred chronic cough underwent clinical evaluations.

Cutaneous Manifestations in Patients on Hemodialysis and Assessment of the Changes in Quality of Life After 12 Weeks of Treatment by a Dermatologist.

Background: Cutaneous manifestations are frequently observed in end-stage kidney disease (ESKD) and affect the quality of life (QoL) of patients undergoing maintenance hemodialysis (HD). Even patients undergoing HD who frequently visit hospitals do not receive active dermatological care. The aims of this study were to assess the cutaneous manifestations of patients undergoing HD and investigate changes in their QoL before and after active treatment by dermatologists.

Could cough hypersensitivity symptom profile differentiate phenotypes of chronic cough?

Background: Recently, cough reflex hypersensitivity has been proposed as a common underlying feature of chronic cough in adults. However, symptoms and clinical characteristics of cough hypersensitivity have not been studied amongst phenotypes of chronic cough. This study aimed to compare symptom features, such as cough triggers and associated throat sensations, of cough hypersensitivity in patients with asthmatic chronic cough and those with refractory chronic cough (RCC).

Predictive Value of the nProfiler 1 Assay for the Efficacy of Adjuvant S-1-Based Doublet Chemotherapy in Stage III Gastric Cancer: A Post-Hoc Analysis of a Randomized Phase III Trial.

Purpose: The nProfiler 1 Stomach Cancer Assay (nProfiler1), designed to predict responses to fluorouracil-based adjuvant chemotherapy, measures the expression of four gastric cancer target genes (GZMB, WARS, SFRP4, and CDX1). The randomized phase III POST trial aimed to compare the efficacies of two adjuvant S-1-based doublet chemotherapies: S-1 plus cisplatin (SP) and S-1 plus docetaxel (DS). This study aimed to validate the nProfiler1 assay using a distinct cohort from the POST trial.

Fluoroscopy-Guided Percutaneous Transthoracic Needle Lung Biopsy with the Aid of Planning Cone-Beam CT: Diagnostic Accuracy and Complications.

Fluoroscopy-guided PTNB for fluoroscopy-identifiable lung lesions has been suggested as a useful method for the pathological diagnosis of lung lesions; however, it is lacking in accuracy and safety compared to CT-guided PTNB. Thus, we aimed to investigate the diagnostic accuracy and complications of fluoroscopy-guided percutaneous transthoracic needle biopsy (PTNB) with the aid of pre-procedural planning cone-beam computed tomography (CBCT) in order to take advantage of their respective strengths. A total of 255 fluoroscopy-guided PTNBs with the aid of planning CBCT were performed.

Feasibility and accuracy of pediatric core temperature measurement using an esophageal probe inserted through the gastric lumen of a second-generation supraglottic airway device: a prospective observational study.

Background: Accurate core temperature measurement in children is crucial; however, measuring esophageal temperature (TE) using a supraglottic airway device (SAD) can be challenging. Second-generation SADs, which have a gastric channel, can measure TE, and reduce gastric air volume. This study aimed to compare TE, measured using a probe inserted through the SAD gastric channel, with tympanic membrane (TTM) and forehead (TZHF) temperatures, measured using a zero-heat-flux cutaneous thermometer, with rectal temperature (TR).

Thermal imaging and deep learning-based fit-checking for respiratory protection.

This study develops an artificial intelligence model to quickly and easily determine correct mask-wearing in real time using thermal videos that ascertained temperature changes caused by air trapped inside the mask. Five types of masks approved by the Korean Ministry of Food and Drug Safety were worn in four different ways across 50 participants, generating 5000 videos. The results showed that 3DCNN outperformed ConvLSTM in both binary and multi-classification for mask wearing methods, with the highest AUROC of 0.

Cholinesterase inhibitor use in amyloid PET-negative mild cognitive impairment and cognitive changes.

Background: Cholinesterase inhibitors (ChEIs) are prescribed for Alzheimer's disease (AD) and sometimes for mild cognitive impairment (MCI) without knowing underlying pathologies and its effect on cognition. We investigated the frequency of ChEI prescriptions in amyloid-negative MCI and their association with cognitive changes in the Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort.

Methods: We included participants with amyloid positron emission tomography (PET)-negative MCI from the ADNI.

The difference in bone mineral density between femur and tibia is related to tibia deformation in endstage knee osteoarthritis.

Background: This study investigated bone mineral density (BMD) around the knee joint to clarify the mechanism by which tibia deformation exceeds that of the femur in patients with end-stage knee osteoarthritis (KOA).

Methods: We retrospectively analyzed 193 patients who underwent total knee arthroplasty for end-stage KOA with varus alignment. Preoperative T-score of the femur neck and femur total using dual-energy X-ray absorptiometry (DXA) and hounsfield units (HU) of the distal femur and proximal tibia using computed tomography (CT) were measured to asess the BMD.

Exploring the concept of disease control in chronic cough.

Background: Disease control in chronic diseases is an overarching concept that reflects the degree to which the goals of therapy are met. However, to date, there is no consensus on the definition of disease control in chronic cough.
