Transcutaneous electrical nerve stimulation and catheter-related bladder discomfort following transurethral resection of bladder tumour: A randomised controlled trial.

Background: Catheter-related bladder discomfort (CRBD) is problematic in patients with a urinary catheter. Transcutaneous electrical nerve stimulation (TENS) is a non-invasive analgesic modality used to relieve various types of pain.

Objectives: We evaluated the effect of TENS on CRBD after transurethral resection of bladder tumours (TURBT).

Comparison of the effects of 5 and 10 L/minute fresh gas flow on emergence from sevoflurane anesthesia: A randomized clinical trial.

Background: A high fresh gas flow of >5 L/minute is commonly used for emergence from inhalation anesthesia. In addition, a high fresh gas flow may have detrimental effects on climate change. However, no study has determined the optimal fresh gas flow for emergence from inhalation anesthesia.

Vitamin C and catheter-related bladder discomfort after transurethral resection of bladder tumor: A double-blind, randomized, placebo-controlled study.

Study Objective: We evaluated the effect of vitamin C administration on postoperative catheter-related bladder discomfort (CRBD).

Design: A double-blind, randomized controlled trial.

Setting: University tertiary hospital.

Comparison of the incidence of intravascular injection using the Tuohy and Quincke needles during ultrasound-guided caudal epidural block: a prospective randomized controlled study.

Introduction: Intravascular injection of a local anesthetic can lead to life-threatening complications, such as deficits in neurological function after caudal epidural block. This study aimed to determine whether the intravascular injection rate of the Tuohy needle is lower than that of the Quincke needle during an ultrasound-guided caudal block.

Methods: Two-hundred and thirty patients were randomized into the Quincke (n=115) and the Tuohy (n=115) needle groups.

Impact of Chart-Derived Frailty Index on 1-Year Mortality After Radical Cystectomy in 1004 Patients with Bladder Cancer.

Background: Radical cystectomy is a major urological procedure with high morbidity and mortality. The chart-derived frailty index (CFI), a measure of preoperative frailty, can be calculated by using demographic and routine laboratory variables. We assessed the impact of CFI on 1-year mortality after radical cystectomy.

Marine plankton exoskeletone-derived hydroxyapatite/polycaprolactone composite 3D scaffold for bone tissue engineering.

3D porous scaffolds based on biodegradable polymers are one of the materials for bone tissue regeneration. In this study, a porous scaffold was prepared using a solvent casting/particulate leaching method that used polycaprolactone (PCL) and hydroxyapatite (OceanBone-HAp) extracted from a marine plankton exoskeleton to achieve excellent bone regeneration. In this study, the morphology and physicochemical properties of the PCL/OceanBone-HAp scaffolds were evaluated using scanning electron microscopy, X-ray diffraction, and porosity analysis.

Enhanced Biocompatibility and Osteogenic Activity of Marine-Plankton-Derived Whitlockite Bone Granules through Bone Morphogenetic Protein 2 Incorporation.

Whitlockite (WH) is a calcium-phosphate-based Mg-containing ceramic with good mechanical properties, rapid resorption, and good osteogenicity. Recently, we successfully synthesized highly porous WH granules using a marine plankton exoskeleton (MP-WH). In the present study, we improved the osteoinductive activity of MP-WH granules by bone morphogenetic protein2 (BMP2) (MP-WH/BMP2).

Marine Plankton-Derived Whitlockite Powder-Based 3D-Printed Porous Scaffold for Bone Tissue Engineering.

Powder-based 3D printing is an excellent technique for the fabrication of complex structural shapes. The outstanding bone remodeling capacity of calcium phosphate bioceramics is a desirable characteristic for such fabrication. Whitlockite (WH) is a calcium phosphate-based ceramic that contains Mg ions and possesses good mechanical properties, rapid resorbability, and promotes osteogenesis.

Increased extracellular maspin levels after mechanical compression in vitro or allergen challenge in vivo.

Maspin secretion from bronchial epithelial cells is substantially elevated by mechanical compression and in BAL fluid of patients with asthma following an allergen challenge, suggesting a potential role of maspin in asthma pathophysiology.

Hybrid clustering based health decision-making for improving dietary habits.

Background: Humans supply a variety of nutrients to their body in dietary life, which are directly related to health. Chronic diseases are long accumulated in the body on account of heredity or living habits, and draw attention as a main issue in the era of disease-controlled longevity. Therefore, it is essential to make health care continuously through the improvement in dietary habits.

Effects of positive end-expiratory pressure on intraocular pressure and optic nerve sheath diameter in robot-assisted laparoscopic radical prostatectomy: A randomized, clinical trial.

Background: There has been no study of the effect of post end-expiratory pressure (PEEP) on intraocular or intracranial pressure during pneumoperitoneum with steep Trendelenburg positioning. We investigated the effects of 5 cmH2O of PEEP on intraocular pressure and optic nerve sheath diameter as a surrogate for intracranial pressure in robot-assisted laparoscopic radical prostatectomy.

Methods: Fifty patients scheduled for robot-assisted laparoscopic radical prostatectomy were divided into a zero-PEEP (ZEEP) group and a 5 cmH2O of PEEP (PEEP) group.

Gender differences in hypertension control among older korean adults: Korean social life, health, and aging project.

Objectives: Controlling blood pressure is a key step in reducing cardiovascular mortality in older adults. Gender differences in patients' attitudes after disease diagnosis and their management of the disease have been identified. However, it is unclear whether gender differences exist in hypertension management among older adults.

Traumatic rupture of the superior oblique muscle tendon.

Traumatic rupture of the superior oblique muscle is rare. We report a case of a 54-year-old man injured by the metal hook of a hanger, resulting in a rupture of the superior oblique muscle tendon. He complained of torsional diplopia when in the primary position.

Serum obestatin/ghrelin ratio is altered in patients after distal gastrectomy.

Background/aims: Ghrelin is a peptide hormone produced mainly in the stomach, and obestatin is derived by proteolytic cleavage of the ghrelin prepro-hormone. The aim of this study was to determine the postoperative serial changes in these hormones and whether hyperplasia of ghrelin-expressing cells occurs in the remnant stomach.

Methods: We prospectively analyzed serial serum samples of 45 early gastric cancer patients and remnant stomach samples of 24 patients.
