Background: This study aimed to evaluate the relationship between clinical experience and death certificate (DC) errors by analyzing DCs written by experienced emergency physicians (EPs).
Methods: DCs issued by four experienced EPs over a 10-year period were retrospectively reviewed. DC errors were divided into major and minor errors based on whether they affected the cause of death (COD) determination.
In recent years, deep learning (DL) has been widely studied using various methods across the globe, especially with respect to training methods and network structures, proving highly effective in a wide range of tasks and applications, including image, speech, and text recognition. One important aspect of this advancement is involved in the effort of designing and upgrading neural architectures, which has been consistently attempted thus far. However, designing such architectures requires the combined knowledge and know-how of experts from each relevant discipline and a series of trial-and-error steps.

Visual question answering requires a deep understanding of both images and natural language. However, most methods mainly focus on visual concept; such as the relationships between various objects. The limited use of object categories combined with their relationships or simple question embedding is insufficient for representing complex scenes and explaining decisions.

Fibrin sealant [Tisseel; n = 107, fibrin-only sealant (FS)] or gelatin matrix hemostatic sealant [FloSeal; n = 51, gelatin matrix sealant (GS)] was applied during tract closure according to surgeon's preference. On the first postoperative day, computed tomography (CT) was scanned for all patients.

A total of 750 eligible patients ≥50 years of age who had previously not responded (International Prostate Symptom Score [IPSS] improvement <4 points) to at least three different kinds of LUTS medications (including a-blocker) for the last 6 months were evaluated as subcohorts for nomogram development (n = 570) and for split-sample validation (n = 180). BOO was defined as Abrams-Griffiths number ≥40, or 20-39.

ETzD was conducted on a concept to estimate the PSA density (PSAD) after hypothetical enucleation of the transitional zone of an enlarged prostate by a non-linear regression prediction model with intrinsic linearity, from the retrospective analysis of PSA change observed actual enucleation by laser. The performance to predict the presence and severity of malignancy was validated by two cohorts of 3,440 prostate biopsies and 2,783 radical prostatectomy specimens.

A total of 292 men with any biopsy-proven PCa (TanyNanyMany) from 12 institutions in Korea were included in this multi-institutional, observational study of prospectively collected data. All luteinizing hormone-releasing hormone (LHRH) agonists were allowed to be investigational drugs.

Methods: Among a total 730 biopsy-proven PCa patients underwent RP, the preoperative mpMRIs of 534 patients were positive, demonstrating one or more PI-RADs V2 grade ≥ 2 lesion(s). Other 196 mpMRIs were classified as negative, without any suspicious lesion.
We evaluated whether the prostate-specific antigen (PSA) mass or free PSA (fPSA) mass ( i.e ., absolute amount of total circulating PSA or fPSA protein, respectively), versus serum PSA or fPSA concentration, improves the accuracy of predicting the total prostate volume (TPV) in relation to obesity.

Recently, multi-parametric magnetic resonance imaging (mpMRI) has recently been increasingly used to enhance clinical staging and characterization of tumor foci. Thus, we tried to investigate the real-life accuracy of combinatory approach of using both transrectal ultrasound (TRUS)-guided prostatic biopsy and mpMRI in predicting the laterality of PCa.

Objectives: To study the volatile sulfur compound (VSC) concentration profile in chronic tonsillitis patients before and after tonsillectomy, and to evaluate the difference between adult and pediatric (children and adolescents) patients.
Methods: Thirty adult patients (older than 20 years old) and 30 pediatric patients (younger than 20 years old) who were assigned to get tonsillectomy due to chronic tonsillitis were enrolled in this prospective nonrandomized clinical study. The concentrations of the three main VSCs related to halitosis (hydrogen sulfide, methyl mercaptan, and dimethyl sulfide) were assessed in each patient using a portable chromatograph (Oral Chroma) at 1 day before operation, postoperative 1 day, 1 week, and 2 weeks.
Despite the increasing attention on the therapeutic potential of Curcuma longa (turmeric), the biological activities of curcuminoids other than curcumin are not well understood. Here, we investigated antivasoconstrictive activities of C. longa extract and its ingredients using freshly isolated rat aortic rings.

The aim of this study was to identify the specific pattern between body mass index (BMI) and psychological distress using the objective personality test. For this study, we investigated BMI and the Korean Military Multiphasic Personality Inventory (MPI).

We describe a novel technique involving inner preputial skin substitution after degloving through a ventral approach that allows sufficient penile skin coverage and evaluated the efficacy and safety of our technique.
Methods: From February 2009 to March 2009, 12 boys with concealed penises underwent correction via our novel technique.
Purpose: To investigate the factors that predict recovery of continence within 3 months after robot-assisted radical prostatectomy (RARP).
Patients And Methods: The charts of 452 patients who underwent RARP with a minimum follow-up period of 3 months were collected prospectively and reviewed retrospectively. Urinary continence was determined using the self-administered validated Expanded Prostate Cancer Index Composite questionnaire during the routine follow-up visits.
In this study, we investigated the effects of a combination of Ginkgo biloba extracts (GBE) and phosphodiesterase type 5 (PDE-5) inhibitors on the muscular tone of the corpus cavernosum and potassium channel activity of corporal smooth muscle cells. Strips of corpus cavernosum from male New Zealand white rabbits were mounted in organ baths for isometric tension studies. After contraction with 1×10⁻⁵ mol l⁻¹ norepinephrine, GBE (0.

The Expanded Prostate Cancer Index Composite (EPIC) is a globally used tool to measure QoL after PCa treatment that comprises urinary, bowel, sexual, and hormonal domains. Acknowledging the need for such a tool applicable to Korean PCa patients, we translated EPIC into Korean and validated the new version.
