RESUMEN
Water vapor therapy using Rezum has been recently introduced as a minimally invasive surgery for benign prostatic hyperplasia and is being increasingly performed. However, there is a lack of real-time images showing this practice and how convective water vapor acts in the prostate gland. In real-time ultrasonography, convective water vapor rapidly spreads throughout the ipsilateral transitional zone and is mostly limited within the transitional zone. For educational purposes, we would like to present a case to help readers understand water vapor therapy by visualizing convective water vapor using real-time ultrasound.
RESUMEN
Rice bakanae, a devastating seed-borne disease caused by Fusarium species requires a more attractive and eco-friendly management strategy. The optimization of plant-mediated silver nanoparticles (AgNPs) as nanofungicides by targeting Fusarium species may be a rational approach. In this study, Azadirachta indica leaf aqueous extract-based AgNPs (AiLAE-AgNPs) were synthesized through the optimization of three reaction parameters: A. indica leaf amount, plant extract-to-AgNO3 ratio (reactant ratio), and incubation time. The optimized green AgNPs were characterized using ultraviolet-visible light (UV-Vis) spectroscopy, field emission scanning electron microscopy (FESEM) with energy dispersive X-ray (EDX) spectroscopy, transmission electron microscopy (TEM), dynamic light scattering (DLS), and powder X-ray diffraction (XRD) techniques. The optimal conditions for producing spherical, unique, and diminutive-sized AgNPs ranging from 4 to 27 nm, with an average size of 15 nm, were 2 g AiLAE at a 1:19 ratio (extract-to-AgNO3) and incubated for 4 h. Fusarium isolates collected from infected soils and identified as F. fujikuroi (40) and F. proliferatum (58 and 65) by PCR were used for seed infestation. The AgNPs exhibited concentration-dependent mycelial growth inhibition with EC50 values ranging from 2.95 to 5.50 µg/mL. The AgNPs displayed exposure time-dependent seed disinfectant potential (complete CFU reduction in F. fujikuroi (40) and F. proliferatum (58) was observed at a concentration of 17.24 µg/mL). The optimized green AgNPs were non-toxic to germinating seeds, and completely cured bakanae under net-house conditions, suggesting their great nano-fungicidal potency for food security and sustainable agriculture.
RESUMEN
Non-gonococcal sexually transmitted infections (STIs) include chlamydia, syphilis, and chancroids. Chlamydia is the most common STI caused by Chlamydia trachomatis and is mainly transmitted through sexual intercourse or vertical transmission at birth. Although symptoms are mostly absent or mild, untreated chlamydial infections in females can lead to pelvic inflammatory disease, chronic pelvic pain, and infertility due to the narrowing of fallopian tubes. Syphilis is caused by Treponema pallidum and is divided into phase I, phase II, latent syphilis, and phase III. The incidence of syphilis, including congenital syphilis, has significantly increased in the United States in recent years. The chronic status of this disease can significantly increase morbidity and potentially affect almost all body organs, which, in rare cases, can lead to death. Additionally, untreated maternal syphilis can lead to fetal death and fatal congenital infections in newborns. Chancroid is an STI caused by Haemophilus ducreyi, and its prevalence is gradually decreasing in Korea and worldwide. The symptoms include shallow genital ulcers with suppurative granulomatous inflammation and tender inguinal lymphadenopathy. Chancroids can be differentiated from syphilitic chancres based on their appearance. In contrast to painless chancres, chancroids are painful. Ureaplasma urealyticum, Ureaplasma parvum, and Mycoplasma hominis are considered symbiotic bacteria. Infections caused by these bacteria are usually not considered STIs and do not require treatment unless they are suspected of being associated with infertility. This article presents the 2023 Korean STI guidelines for non-gonococcal bacterial infections.

The Korean Association of Urogenital Tract Infection and Inflammation (KAUTII) and the Korea Disease Control and Prevention Agency updated the guidelines for human papillomavirus (HPV) vaccine against sexually transmitted HPV infections in Korea to respond to changing epidemiologic trends, evolving scientific evidence, and advances in laboratory diagnostics and research. Main purpose and recommendation of vaccination against HPV are as follows: (1) the purpose of HPV vaccine is to reduce the risk of genital warts and HPV-related cancers including cervical and vulvar cancer, head and neck cancer, anal cancer, and penile cancer; (2) in Korea, bivalent (16, 18) vaccines, quadrivalent vaccines (6, 11, 16, 18), and 9-valent vaccines (6, 11, 16, 18, 31, 33, 45, 52, 58) are used depending on the type of HPV; (3) bivalent and quadrivalent vaccines are national immunizations targeting girls aged 11-12 years and low-income young females aged 18-26 years (age and range of inoculation: routinely administered at 11 or 12 years of age, 2 doses at 0 and 6 months for 12-14 years of age; for females aged 15-26 years, 3 doses depending on the type of vaccine; vaccination can be given to those aged up to 45 years through consultation with a clinician); (4) in the case of administering 2 doses, at least 5 months apart; in the case of administering 3 doses, it is recommended to keep 4 weeks between the 1st and 2nd doses, 12 weeks between the 2nd and 3rd doses, and 5 months between the 1st and 3rd doses; (5) immunocompromised patients such as those with HIV, malignant neoplasms, and autoimmune diseases, and those undergoing transplantation or immunosuppressive therapy should receive 3 doses. HPV vaccine is not recommended during pregnancy.

Canola meal, a by-product of canola oil processing, is a source of bioactive compounds that show antioxidant and skin anti-aging effects through upcycling (i.e., creative reuse). Here we describe the antioxidant and skin anti-aging effects of canola meal extract (CME) obtained by upcycling canola meal. The antioxidant capacity of CME is due in part to its antioxidative phenolics. Seven phenolics, including sinapine and sinapic acid, in CME were identified using ultra-high-performance liquid chromatography-Orbitrap mass spectrometry. Addition of CME (1000 µg/mL) to human dermal fibroblast neonatal cells significantly (p < 0.05) reduced matrix metalloproteinase-12 production and increased pro-collagen Ι alpha 1 content in response to ultraviolet B-induced oxidative stress compared with cells without CME. These results suggest that CME can serve as a functional food ingredient with antioxidant capacity and anti-aging effects on the skin.
RESUMEN
The incidence of gonorrhea has increased significantly in recent years in the United States, especially among sexually active twenty-year-olds. Although the incidence of gonorrhea has decreased in Korea since the early 2000s, it is still common among people in their twenties. Nucleic acid amplification test (NAAT) is the most sensitive diagnostic test for detecting gonococcal infection. Gram-staining is a simple and useful laboratory test for diagnosing symptomatic male gonococcal urethritis. Although bacterial culture can be used to detect antimicrobial susceptibility, its sensitivity is lower than that of NAAT. Treatment for uncomplicated gonorrhea infection is a single intramuscular injection of ceftriaxone 500 mg. Doxycycline (100 mg twice daily for 7 days) is added if there is a possibility of co-infection with chlamydia. If ceftriaxone is difficult to use, spectinomycin 2 g can be injected intramuscularly in Korea. Patients with gonorrhea should have repeated examinations within three months at the exposure site because of a high risk of re-infection. A person diagnosed with gonorrhea should discuss the nature of the infection, the importance of informing partners, when sexual activity can resume, and how to reduce the risk of sexually transmitted infections.

The Korean Association of Urogenital Tract Infection and Inflammation and the Korea Disease Control and Prevention Agency regularly update, revise, and develop new content for the Korean sexually transmitted infection (STI) guidelines. These professional bodies respond to changing epidemiological trends and evolving scientific evidence, and consider advances in laboratory diagnostics and research. The principal recommendations of the 2023 Korean STI guidelines in terms of viral infection follow: 1) If genital herpes recurs more than 4-6 times annually, suppressive therapy with acyclovir 400 mg orally 2 times/day or famciclovir 250 mg orally 2 times/day or valacyclovir 500 mg orally once a day (for patients with <10 episodes/year) or valacyclovir 1 g orally once daily (for patients with ≥10 episodes/year) is recommended to prevent recurrence; 2) molecular human papillomavirus (HPV) testing is not recommended as a routine test for STI status, nor for determination of HPV vaccination status; and 3) patients should inform their current sexual partners about anogenital warts because the types of HPV that cause such warts can be passed to partners. These guidelines will be updated every 5 years and will be revised when new knowledge on STIs becomes available and there is a reasonable need to improve the guidelines. Physicians and other healthcare providers can use the guidelines to assist in the prevention and treatment of STIs.

The Korean Association of Urogenital Tract Infection and Inflammation and the Korea Disease Control and Prevention Agency updated the Korean sexually transmitted infections (STIs) guidelines to respond to the changing epidemiologic trends, evolving scientific evidence, and advances in laboratory diagnostics and research. The main recommendations in the Mycoplasma genitalium infection parts of the Korean STIs guidelines 2023 revision are as follows: 1) For initial treatment: azithromycin 500 mg orally in a single dose, then 250 mg once daily for 4 days. 2) In case of treatment failure or recurrence, a macrolide susceptibility/resistance test is required, when susceptibility/resistance test is not feasible, doxycycline or minocycline 100 mg orally twice daily for 7 days, followed by azithromycin 1 g orally on the first day, then azithromycin 500 mg orally once daily for 3 days and then a test-of-cure should be considered 3 weeks after completion of therapy. 3) In case of macrolide sensitivity, doxycycline or minocycline 100 mg orally twice daily for 7 days, followed by azithromycin 1 g orally initial dose, then azithromycin 500 mg orally once daily for 3 days. 4) In case of macrolide resistance, doxycycline or minocycline 100 mg orally twice daily for 7 days, followed by moxifloxacin 400 mg orally once daily for 7 days. In the Korean STIs guideline 2023, macrolide resistance-guided antimicrobial therapy was emphasized due to the increased prevalence of macrolide resistance worldwide. Therefore, in case of treatment failure or recurrence, a macrolide susceptibility/resistance test is required.

BACKGROUND: Exposure to benzyl butyl phthalate (BBP) may induce disorders in the male reproductive system. However, the molecular mechanisms remain unknown. Here we investigated the effect of BBP on testosterone production and its molecular mechanisms. Furthermore, we also investigated the role of gomisin N (GN) from Schisandra chinensis (S. chinensis) in testosterone synthesis in TM3 Leydig cells. METHOD AND RESULTS: First, we examined the effects of BBP on expression levels of testosterone biosynthesis-related genes (StAR, CYP11α1, CYP17α1, 3ßHSD, and 17ßHSD) and attenuation-related genes (CYP1ß1, CYP19α1, and Srd5α1-3). Although testosterone biosynthesis-related genes did not change, attenuation-related genes such as CYP1ß1 and CYP19α1 were upregulated with ROS generation and testosterone level attenuation in the presence of 50 µM of BBP. However, the compound with the highest ROS and ONOO- scavenging activity from S. chinensis, GN, significantly reversed the expression of BBP-induced testosterone attenuation-related gene to normal levels. Subsequently, GN improved the testosterone production levels in TM3 Leydig cells. These events may be regulated by the antioxidant effect of GN. CONCLUSIONS: On conclusion, our study suggests, for the first time, that BBP impairs testosterone synthesis by the modulation of CYP1ß1 and CYP19α1 expression in TM3 cells; GN could potentially minimize the BBP-induced dysfunction of TM3 cells to produce testosterone by suppressing CYP19α1 expression.

BACKGROUND: Fluoroquinolone has been the historic choice of antimicrobial prophylaxis for transrectal ultrasound (TRUS) guided prostate biopsy. However, increased fluoroquinolone resistance and recent restrictions of its use for antimicrobial prophylaxis has led to the emergence of alternative agents for antimicrobial prophylaxis for TRUS guided prostate biopsy including fosfomycin and cephalosporins. This study aimed to compare the efficacy of fosfomycin and a second-generation cephalosporin flumarin as alternative antimicrobials for TRUS-guided prostate biopsy in terms of the incidence of infectious complications after TRUS-guided prostate biopsy. METHODS: A retrospective chart review of all patients who underwent TRUS-guided prostate biopsy between November 2009 to January 2023 was undertaken. Comparison of baseline characteristics and the incidence of infectious complications was done between those who received fosfomycin as antimicrobial prophylaxis for TRUS-guided prostate biopsy and those who received flumarin. Multivariate logistic regression analysis was conducted to identify risk factors for infectious complications after TRUS-guided prostate biopsy. RESULTS: Of 2,900 patients identified as eligible candidates for analysis, 333 (11.5%) received fosfomycin and 2,567 (88.5%) received flumarin. The overall rate of infectious complications was approximately 3% lower in patients who received fosfomycin, although such difference did not reach statistical significance (5.7% vs. 8.6%, p = 0.074). Multivariate logistic regression analysis showed that history of operation done under general anaesthesia within six months of the biopsy (odds ratio [OR]: 2.216; 95% confidence interval [CI]: 1.042-4.713; p = 0.039) and history of prior antimicrobial use within six months (OR: 1.457; 95% CI: 1.049-2.024; p = 0.025) were significant risk factors for infectious complications after TRUS-guided prostate biopsy. CONCLUSION: Fosfomycin was comparable to second-generation cephalosporin flumarin in preventing infectious complications after TRUS-guided prostate biopsy. Coupled with its properties such as ease of administration, low adverse effects, low resistance rate, and low collateral damage, fosfomycin might be an attractive alternative antimicrobial prophylaxis for TRUS-guided prostate biopsy.

There is a dearth of evidence indicating the effectiveness of psychological interventions targeting depression and/or posttraumatic stress disorder (PTSD) for Black women in the United States (US) exposed to intimate partner violence (IPV). We searched PubMed, MEDLINE, PsycINFO, EBSCOhost, Social Sciences, Social Sciences Full Text, Social Work Abstracts, and Cochrane databases between September 2021 and October 2022, for original studies of randomized control trials (RCTs) reporting depression and/or PTSD interventions delivered to US Black women with histories of IPV. Of the 1,276 articles, 46 were eligible and 8 RCTs were ultimately included in the review; interventions for depression (four interventions, n = 1,518) and PTSD (four interventions, n = 477). Among Depression and PTSD interventions (one intervention, n = 208), Beck's Depression Inventory II indicated M = 35.2, SD = 12.6 versus M = 29.5, SD = 13.1, <.01, and Davidson Trauma Scale indicated M = 79.4, SD = 31.5 versus M = 72.1, SD = 33.5, <.01, at pre- and post-intervention respectively. Also, some interventions reported severity of depression M = 13.9 (SD = 5.4) versus M = 7.9 (SD = 5.7) < 0.01, and PTSD (M = 8.08 vs. M = 14.13, F(1,117) = 9.93, p < .01) at pre- and post-intervention respectively. Publication bias was moderate and varied between 12 and 17 via the Downs and Black Checklist for Methodological Rigor for RCTs. Psychological interventions targeting depression and/or PTSD for Black women with histories of IPV reflect moderate improvement. Interventions that account for cultural nuances specific to Black women are fundamental for improving outcomes for survivors presenting with depression and/or PTSD.
RESUMEN
A prospective observational study involving consecutive patients diagnosed with symptomatic urolithiasis was conducted to evaluate the serial change of urinary protein and 24-h urine chemistry with time after surgical procedures for urolithiasis. A consecutive 24-h urine samples, including calcium, uric acid and citrate were collected before surgical treatments, 4 ~ 8 weeks after surgery and 6 months after surgery. The urinary protein to creatinine ratio was also repeated at each timepoint. Forty-seven patients completed the study. The quantity of 24-h urine chemistry, including calcium, uric acid and citrate, changed over time and tended to increase (p = 0.013, 0.076 and 0.004, respectively), but the changes were not prominent during short-term follow-up. In contrast, the urinary protein to creatinine ratio decreased (p < 0.001) after surgical treatment for symptomatic renal stones, and the change was reflected in short-term follow-up. However, the serial changes in the urinary protein to creatinine ratio were significantly related to the serial changes in the 24-h urinary chemistry (p < 0.001). Surgical decompression for symptomatic urolithiasis could decrease the urinary protein to creatinine ratio, indicating improvement from renal damage, which may be reflected in the increase in 24-h urinary chemistry, including calcium, uric acid and citrate. These results strengthen the previous guidelines for the timing of 24-h urine collection and provide new insight into the optimal timing from the perspective of renal function.

Electrospun nanofibers have been applied as a new technology for gas indicators in food intelligent packaging. A poly(ε-caprolactone) (PCL)/red cabbage anthocyanin (RCA)-based nanofiber volatile amines gas indicator was developed by applying a bi-solvent of acetic acid (AA) and formic acid (FA) in electrospinning. The visibility of color change was improved from pink to blue, compared to blue to yellow-green, when using a single solvent of AA. The solutes of PCL (12.5, 15, 17.5, and 20%) and RCA (10, 20, 30, and 40%) and the solvents of AA/FA (9:1, 7:3, 5:5, 3:7, and 1:9) were applied in electrospinning under the condition of 12.5 cm, 1.0 mL/h, and 20 kV. The optimal microstructure with the thinnest fiber diameter and constant arrangement without forming NF beads appeared under the 7:3 FA/AA, 15% PCL, and 20% RCA condition. The indicator changed from pink to blue with the values of total color change (ΔE) of 10, 14, and 18 when exposed to the saturated gas of ammonia solutions of 8, 80, and 800 mM, respectively. The indicator was stable and unchanged in color for 28 days when exposed to light at room temperature. In the application to mackerel packaging, the built-in indicator changed from pink to purple regardless of storage temperature when the spoilage point was reached.
RESUMEN
A time-temperature indicator (TTI) based on acid-base reaction was developed by applying a new pH dye composed of cysteine-loaded chitosan (Cys-CS) microspheres and silver nanoparticles (AgNPs). It was hypothesized that cysteine released by the disintegration of Cys-CS microspheres at a critical pH would cause AgNPs to aggregate, leading to color change. Cys-CS microspheres were produced as water-in-oil (paraffin oil, MCT oil, soybean oil) emulsions according to the KOH addition method. An enzymatic TTI was made using glucose oxidase, glucose, and catalase. Only paraffin oil produced Cys-CS microspheres (average diameter, 335 ± 100 µm), whereas the others did not, probably due to saponification with KOH. FTIR analysis confirmed that cysteine was encapsulated in the microspheres. The microspheres disintegrated at pH 6.18 in a titration test. The TTI pH gradually decreased and showed a sudden color change at pH 6.10, which was similar to the critical pH of microsphere disintegration.
RESUMEN
Background and Objectives: To determine the percentage of breast cancers detectable by fused diffusion-weighted imaging (DWI) using unenhanced magnetic resonance imaging (MRI) and abbreviated post-contrast-enhanced MRI. Materials and Methods: Between October 2016 and October 2017, 194 consecutive women (mean age, 54.2 years; age range, 28-82 years) with newly diagnosed unilateral breast cancer, who underwent preoperative 3.0 T breast MRI with DWI, were evaluated. Both fused DWI and abbreviated MRI were independently reviewed by two radiologists for the detection of index cancer (which showed the most suspicious findings in both breasts), location, lesion conspicuity, lesion type, and lesion size. Moreover, the relationship between cancer detection and histopathological results of surgical specimens was evaluated. Results: Index cancer detection rates were comparable between fused DWI and abbreviated MRI (radiologist 1: 174/194 [89.7%] vs. 184/194 [94.8%], respectively, p = 0.057; radiologist 2: 174/194 [89.7%] vs. 183/194 [94.3%], respectively, p = 0.092). In both radiologists, abbreviated MRI showed a significantly higher lesion conspicuity than fused DWI (radiologist 1: 9.37 ± 2.24 vs. 8.78 ± 3.03, respectively, p < 0.001; radiologist 2: 9.16 ± 2.32 vs. 8.39 ± 2.93, respectively, p < 0.001). The κ value for the interobserver agreement of index cancer detection was 0.67 on fused DWI and 0.85 on abbreviated MRI. For lesion conspicuity, the intraclass correlation coefficients were 0.72 on fused DWI and 0.82 on abbreviated MRI. Among the histopathological factors, tumor invasiveness was associated with cancer detection on both fused DWI (p = 0.011) and abbreviated MRI (p = 0.004, radiologist 1), lymphovascular invasion on abbreviated MRI (p = 0.032, radiologist 1), and necrosis on fused DWI (p = 0.031, radiologist 2). Conclusions: Index cancer detection was comparable between fused DWI and abbreviated MRI, although abbreviated MRI showed a significantly better lesion conspicuity.
RESUMEN
Background: We assessed the ability of the combination of multiparametric magnetic resonance imaging (mpMRI) and transperineal template-guided mapping biopsy (TTMB) to determine the eligibility for focal therapy (FT) (hemiablation) in men and compared it with that of histology from radical prostatectomy (RP) specimens. Materials and methods: In this study, 120 men who underwent mpMRI, TTMB, and RP in a single tertiary center from May 2017 to June 2021 were analyzed. The criteria of hemiablation eligibility were unilateral low-to intermediate-risk prostate cancer (limited to a maximum of International Society of Urological Pathology (ISUP) grade group 3 and prostate-specific antigen (PSA) <20 ng/mL) and clinical stage ≤T2. Evidence of non-organ-confined disease or contralateral Prostate Imaging Reporting and Data System (PI-RADS) v2 score ≥4 on mpMRI was classified as ineligible for hemiablation. Clinically significant cancer at RP was defined as any of the following: (1) ISUP grade group 1 with tumor volume ≥1.3 mL; (2) ISUP grade group ≥2; or (3) the presence of advanced stage (≥pT3). Results: Of the 120 men, data of 52 men who met the selection criteria for hemiablation were compared with final RP findings. Of these 52 men, 42 (80.7%) could be considered suitable for hemiablation on RP. The sensitivity, specificity, and accuracy of mpMRI and TTMB in predicting FT eligibility were 80.7%, 85.1%, and 82.5%, respectively. The rate of undetected contralateral significant cancer was 10 (19.2%) on mpMRI and TTMB. Six had bilateral significant cancer and four had small volumes of ISUP grade group ≥2. Conclusions: The combination of mpMRI and TTMB substantially improves the prediction of potential candidates for hemiablation based on consensus recommendations. Improved selection criteria and further investigative tools are required to improve patient selection for hemiablation.
RESUMEN
PURPOSE: Recent studies have highlighted increasing infectious complications due to fluoroquinolone (FQ)-resistant organisms in men undergoing transrectal ultrasound-guided prostate biopsy (TRUSPB). This study investigated whether fosfomycin (FM)-based antibiotic prophylaxis reduces infections after TRUSPB and identified risk factors for infective complications. MATERIALS AND METHODS: A multicenter study was conducted in the Republic of Korea from January 2018 to December 2021. Patients undergoing prostate biopsy with FQ or FM-based prophylaxis were included. The primary outcome was the post-biopsy infectious complication rate after FQ (group 1) or FM-based antibiotic prophylaxis with FM alone (group 2) or FQ and FM (group 3). Risk factors for infectious complications after TRUSPB were secondary outcomes. RESULTS: Patients (n=2,595) undergoing prostate biopsy were divided into three groups according to the type of prophylactic antibiotics. Group 1 (n=417) received FQ before TRUSPB. Group 2 (n=795) received FM only and group 3 (n=1,383) received FM and FQ before TRUSPB. The overall post-biopsy infectious complication rate was 1.27%. The infectious complication rates were 2.4%, 1.9%, and 0.5% in groups 1, 2, and 3, respectively (p=0.002). In multivariable analysis, predictors of post-biopsy infectious complications included an association with health care utilization (adjusted odds ratio [OR], 4.66; 95% confidence interval [CI], 1.74-12.4; p=0.002) and combination antibiotic prophylaxis (FQ and FM) (adjusted OR, 0.26; 95% CI, 0.09-0.69; p=0.007). CONCLUSIONS: In comparison with monotherapy with FM or FQ, combination antibiotic prophylaxis (FQ and FM) showed a lower rate of infectious complications after TRUSPB. Utilization of health care was an independent risk factor for infectious complications after TRUSPB.

BACKGROUND/OBJECTIVES: Male hypogonadism is a condition where the body does not produce enough testosterone and significantly impacts health. Age, obesity, genetics, and oxidative stress are some physiological factors that may contribute to testosterone deficiency. Previous studies have shown many pharmacological benefits of Schisandra chinensis (S. chinensis) Baillon as an anti-inflammatory and antioxidant. However, the molecular mechanism of attenuating hypogonadism is yet to be well established. This research was undertaken to study the effects of S. chinensis extract (SCE) on testosterone deficiency. MATERIALS/METHODS: S. chinensis fruit was pulverized and extracted using 60% aqueous ethanol. HPLC analysis was performed to analyze and quantify the lignans of the SCE. RESULTS: The 2,2-diphenyl-2-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) scavenging assays confirmed that the SCE and its major lignans (schisandrol A and gomisin N) inhibit oxidative stress. Effects of SCE analysis on the testosterone level under oxidative stress conditions revealed that both schisandrol A and gomisin N were able to recover the lowered testosterone levels. Through mRNA expression of TM3 Leydig cell, we observed that the SCE lignans were able to induce the enzymes involved in testosterone biosynthesis-related genes such as 3ß-HSD4 (P < 0.01 for SCE, and P < 0.001 for schisandrol A and gomisin N), 17ß-HSD3 (P < 0.001 for SCE, schisandrol A and gomisin N), and 17, 20-desmolase (P < 0.01 for schisandrol A, and P < 0.001 for SCE and gomisin N). CONCLUSIONS: These results support that SCE and its active components could be potential therapeutic agents for regulating and increasing testosterone production.
RESUMEN
PURPOSE: The purpose of this study is to investigate disease trend of genital wart through changes in each treatment method over the past 10 years in Korea. MATERIALS AND METHODS: From 2010 to 2019, surgical treatment including cauterization, excision, cryotherapy, and laser therapy, non-surgical treatment such as podophyllin, and surgical treatment for anorectal lesion were extracted and analyzed from 2010 to 2019. For each treatment method, characteristics such as sex, age, region, medical cost and average number of procedures were analyzed. RESULTS: The number of patients following all treatment modalities increased every year. Surgical treatment of genital wart and anorectal wart showed a significant increase in male patients. Number of non-surgical treatment decreased in males but increased in females. Surgical removal of the anorectal wart increased more than 250% in over 10 years, and males underwent surgery 4 times more than females. In both surgery and non-surgery, the mean session was higher in males. Most of them were carried out in primary medical institutions. In Seoul and Gyeonggi-do, the largest number of patients received treatment regardless of treatment method. CONCLUSIONS: Treatment for genital warts has increased rapidly over the past 10 years, and the increase in males is remarkable. The main treatment was surgery, and males mainly received surgical treatment, and females mainly received drug treatment. The primary medical institution was in charge of the most treatment. As the number of patients and related medical expenses are increasing rapidly, more attention and response to diseases are needed.
