Abstract
The Net Zero Emissions (NZE) concept has created momentum for climate commitment made by national governments, cities, industries and individual companies. However, evidence of tangible decarbonisation is limited. Here we identify precarious differences between the scientific origin of NZE and its social representation in the wider public and explore the consequences of the resulting science-action gap for achieving global climate goals. A particular focus is given to 'offsetting', which is closely connected to the practical delivery of NZE but typically ignores that different types or carbon credits have different environmental efficacy. Revisiting the science related to the global carbon cycle demonstrates that a heavy reliance on any carbon offsetting that is not a permanent removal presents a real risk. Moreover, competition over scarce 'removal credits' distracts from the real tasks at hand, namely to rapidly decrease fossil fuel emissions, actively remove carbon through restoration, and protect existing terrestrial carbon sinks. Establishing separate targets for these distinct actions is an essential step towards disentangling current confusion. Whilst a 'race to net zero' may trigger innovation in the decarbonisation space, the restoration and protection of carbon sinks demands a collective approach where actors should focus on how to make real and verifiable contributions rather than claiming individual net zero scores.

Abstract
Water vapor therapy using Rezūm 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.

Abstract
BACKGROUND Total mesorectal excision using conventional straight fixed devices may be technically difficult because of the narrow and concave pelvis. Several laparoscopic articulating tools have been introduced as an alternative to robotic systems. The aim of this study was to compare perioperative outcomes between laparoscopic low anterior resection using ArtiSential® and robot-assisted surgery for rectal cancer. METHODS This retrospective study included 682 patients who underwent laparoscopic or robotic low anterior resection for rectal cancer from September 2018 to December 2021. Among them, 82 underwent laparoscopic surgery using ArtiSential® (group A) and 201 underwent robotic surgery (group B). A total of 73 [group A; 66.37 ± 11.62; group B 65.79 ± 11.34] patients were selected for each group using a propensity score matching analysis. RESULTS There was no significant difference in the baseline characteristics between group A and B. Mean operative time was longer in group B than A (163.5 ± 61.9 vs 250.1 ± 77.6 min, p < 0.001). Mean length of hospital stay was not significantly different between the two groups (6.2 ± 4.7 vs 6.7 ± 6.1 days, p = 0.617). Postoperative complications, reoperation, and readmission within 30 days after surgery were similar between the two groups. Pathological findings revealed that the circumferential resection margins were above 10 mm in both groups (11.00 ± 7.47 vs 10.17 ± 6.25 mm, p = 0.960). At least 12 lymph nodes were sufficiently harvested, with no significant difference in the number harvested between the groups (20.5 ± 9.9 vs 19.7 ± 7.3, p = 0.753). CONCLUSIONS Laparoscopic low anterior resection using ArtiSential® can achieve acceptable clinical and oncologic outcomes. ArtiSential®, a multi-joint and articulating device, may serve a feasible alternative approach to robotic surgery in rectal cancer.

Abstract
PURPOSE The purpose of this meta-analysis is to study the impact of varicocele repair in the largest cohort of infertile males with clinical varicocele by including all available studies, with no language restrictions, comparing intra-person conventional semen parameters before and after the repair of varicoceles. MATERIALS AND METHODS The meta-analysis was performed according to PRISMA-P and MOOSE guidelines. A systematic search was performed in Scopus, PubMed, Cochrane, and Embase databases. Eligible studies were selected according to the PICOS model (Population: infertile male patients with clinical varicocele; Intervention: varicocele repair; Comparison: intra-person before-after varicocele repair; Outcome: conventional semen parameters; Study type: randomized controlled trials [RCTs], observational and case-control studies). RESULTS Out of 1,632 screened abstracts, 351 articles (23 RCTs, 292 observational, and 36 case-control studies) were included in the quantitative analysis. The before-and-after analysis showed significant improvements in all semen parameters after varicocele repair (except sperm vitality); semen volume: standardized mean difference (SMD) 0.203, 95% CI: 0.129-0.278; p<0.001; I²=83.62%, Egger's p=0.3329; sperm concentration: SMD 1.590, 95% CI: 1.474-1.706; p<0.001; I²=97.86%, Egger's p<0.0001; total sperm count: SMD 1.824, 95% CI: 1.526-2.121; p<0.001; I²=97.88%, Egger's p=0.0063; total motile sperm count: SMD 1.643, 95% CI: 1.318-1.968; p<0.001; I²=98.65%, Egger's p=0.0003; progressive sperm motility: SMD 1.845, 95% CI: 1.537%-2.153%; p<0.001; I²=98.97%, Egger's p<0.0001; total sperm motility: SMD 1.613, 95% CI 1.467%-1.759%; p<0.001; l2=97.98%, Egger's p<0.001; sperm morphology: SMD 1.066, 95% CI 0.992%-1.211%; p<0.001; I²=97.87%, Egger's p=0.1864. CONCLUSIONS The current meta-analysis is the largest to date using paired analysis on varicocele patients. In the current meta-analysis, almost all conventional semen parameters improved significantly following varicocele repair in infertile patients with clinical varicocele.

Abstract
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.

Abstract
Background To evaluate the efficacy and safety of Cervi Parvum Cornu, Angelicae Gigantis Radix and Glycyrrhizae Radix complex (CAG) in men with moderate lower urinary tract symptoms (LUTS). Materials and methods From November 2020 to January 2022, participants with International Prostate Symptom Score (IPSS) of 12-19 in two centers were recruited and randomize into three groups: a CAG 500 mg/day group (CAG 500), a CAG 1000 mg/day group (CAG 1000), and a placebo group (PG). They were treated for 12 weeks. The primary endpoint was change of IPSS at the end of study from baseline. Secondary end points included change of prostate specific antigen (PSA), testosterone, dihydrotestosterone (DHT), maximum urinary flow rate (Q max), post-void residual volume (PVR), International Index of Erectile Function (IIEF), and drug safety. Results A total of 103 patients were able to finish the study according to the study protocol. Total IPSS and sub-scores (residual urine sensation, frequency, weak stream, hesistancy, nocturia, and quality of life) in CAG 500 and CAG 1000 were significantly improved at the 12th week compared to those of the PG. Changes of serum PSA, DHT, and testosterone levels at the 12th week from baseline did not show significant differences among the three groups. Q max and PVR changes did not show significant differences among the three groups either. Total IIEF and sub-scores (erectile function, orgasmic function, sexual desire, intercourse satisfaction) in CAG 1000 were significantly improved at 12th week compared to those in PG. No significant adverse events were found. Conclusions CAG is well tolerated in patients with moderate LUTS. Treatment with CAG for 12 weeks has a therapeutic effect on moderate LUTS.

Abstract
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.

Abstract
PURPOSE/OBJECTIVE(S) The gut microbiome is an emerging biomarker that is known to have a pivotal role in the development of diverse human diseases. This prospective cohort study aimed to investigate the association between gut microbial changes and acute gastrointestinal (GI) toxicities in prostate cancer patients receiving definitive radiation therapy (RT). MATERIALS/METHODS Seventy-nine fecal samples from 16 prostate cancer patients were analyzed. Stool samples were collected at the following timepoints: pre-RT (prRT), 2 weeks after the start of RT (RT-2w), 5 weeks after the start of RT (RT-5w), 1 month after completion of RT (poRT-1m), and 3 months after completion of RT (poRT-3m). Total RT doses were 69.6‒74.4 Gy at 2.4 Gy per fraction in the high-dose area and 45‒50.4 Gy at 1.8 Gy per fraction in the low-dose area. Alpha- and beta-diversity were estimated. We computed the microbial community polarization index (MCPI) as an indicator of RT-induced dysbiosis. A linear mixed effect model was adopted to evaluate time effects after RT. Metabolic pathway abundances were inferred using bioinformatics tools. RESULTS Seven patients experienced ≥ grade 1 acute GI toxicities. Patients experiencing toxicity had lower alpha diversity, especially at RT-2w (P = 0.037) and RT-5w (P = 0.003), with the microbiota enriched in Fusobacteria, Fusobacterium, and Bacteroides fragilis. Patients receiving a large RT field had a trend of lower alpha diversity, particularly at poRT-1m (P = 0.027), with the microbiota enriched in Propionibacteriaceae, Cutibacterium, and Prevotella stercorea. Compared with the MCPI at prRT, the MCPI observed at poRT-1m in patients experiencing toxicities was significantly elevated (P = 0.007). In terms of predicted metabolic pathways, we found linearly decreasing pathways, including carbon fixation pathways in prokaryotes (P = 0.035) and the bacterial secretion system (P = 0.005), in patients who experienced toxicities. Regarding the RT field, no linear trend of functional pathways was found across timepoints. CONCLUSION We showed RT-induced dysbiosis in the gut microbiome among patients with prostate cancer who experienced toxicities or received a large RT field. Reduced diversity and elevated RT-related MCPI could be helpful for developing individualized RT approaches. Longitudinal analysis revealed dynamic changes in several microbes and metabolic pathways, which should be validated in a whole metagenome sequencing study.

Abstract
Introduction: We aimed to evaluate the efficacy of bipolar cauterization for tract site bleeding during standard percutaneous nephrolithotomy (PCNL). Methods and Materials: We defined tract site bleeding as when the visual field across the parenchymal tract starts to bleed while the sheath of a balloon dilator is being withdrawn just before the operation is completed. Among 181 patients, 90 patients showed no significant bleeding, and 91 patients required further procedures to resolve tract site bleeding. In cases of unresolved tract site bleeding, either nephrostomy placement (n = 60) or cauterization (n = 31) was performed. The outcomes of three groups (no procedure group, nephrostomy group and cauterization group) were compared. Results: The median decrease in hemoglobin at 2-hour intervals postoperatively was -1.75, -1.0, and -0.2 in the nephrostomy, cauterization, and no procedure groups, respectively (P < .001). There were 25 patients (41.7%) who received transfusions in the nephrostomy group, whereas only 1 patient (3.2%) received a transfusion in the cauterization group (P < .001). Conclusion: The bipolar cauterization of bleeding points at the end of PCNL could efficiently decrease tract site bleeding and reduce the need for transfusion.

Abstract
BACKGROUND The natural course of polypoid lesions in the ureter during ureteroscopic stone surgery was not yet clarified. METHODS Patient data were collected prospectively from six teaching hospitals between 2019 and 2021. Patients with polypoid lesions in the ureter distal to ureteral stones were included during ureteroscopy. Computed tomography was performed on all enrolled patients three months after the procedure. Follow-up ureteroscopy was performed only if the patient consented, due to the need for general anesthesia and ethical considerations. RESULTS Among the 35 patients who were followed up, 14 had fibroepithelial polyps and 21 had inflammatory polyps. Twenty of the followed-up patients underwent ureteroscopy, and nine of them had fibroepithelial polyps. Although fibroepithelial polyps did not disappear in the follow-up ureteroscopy (p = 0.002), the rate of postoperative hydronephrosis was not higher in the fibroepithelial group than in the inflammatory group. Postoperative ureteral stricture and moderate-to-severe hydronephrosis were found to be closely related to the number of resected polyps, regardless of the type of polyp (p = 0.014 and 0.006, respectively). CONCLUSION Fibroepithelial polyps in the ureter may persist after treatment of adjacent ureter stones. However, conservative management may be preferable to active removal of ureteral polyps because fibroepithelial polyps may not contribute to clinically significant hydronephrosis after surgery, and inflammatory polyps disappear spontaneously. Hasty resections of polyps may increase the risk of ureteral stricture.

Abstract
Ambipolar field-effect transistors (FETs) possessing both electron and hole carriers enable implementation of novel reconfigurable transistors, artificial synaptic transistors, and output polarity controllable (OPC) amplifiers. Here, we fabricated a two-dimensional (2D) material-based complementary ambipolar FET and investigated its electrical characteristics. Properties of ohmic-like contacts at source/drain sides were verified from output characteristics and temperature-dependent measurements. The symmetry of electron and hole currents can be easily achieved by optimization of the MoS2 or WSe2 channels, different from the conventional ambipolar FET with fundamental issues related to Schottky barriers. In addition, we demonstrated successful operation of a complementary inverter and OPC amplifier, using the fabricated complementary ambipolar FET based on 2D materials.

Abstract
Global aviation operations contribute to anthropogenic climate change via a complex set of processes that lead to a net surface warming. Of importance are aviation emissions of carbon dioxide (CO2), nitrogen oxides (NOx), water vapor, soot and sulfate aerosols, and increased cloudiness due to contrail formation. Aviation grew strongly over the past decades (1960-2018) in terms of activity, with revenue passenger kilometers increasing from 109 to 8269 billion km yr-1, and in terms of climate change impacts, with CO2 emissions increasing by a factor of 6.8 to 1034 Tg CO2 yr-1. Over the period 2013-2018, the growth rates in both terms show a marked increase. Here, we present a new comprehensive and quantitative approach for evaluating aviation climate forcing terms. Both radiative forcing (RF) and effective radiative forcing (ERF) terms and their sums are calculated for the years 2000-2018. Contrail cirrus, consisting of linear contrails and the cirrus cloudiness arising from them, yields the largest positive net (warming) ERF term followed by CO2 and NOx emissions. The formation and emission of sulfate aerosol yields a negative (cooling) term. The mean contrail cirrus ERF/RF ratio of 0.42 indicates that contrail cirrus is less effective in surface warming than other terms. For 2018 the net aviation ERF is +100.9 milliwatts (mW) m-2 (5-95% likelihood range of (55, 145)) with major contributions from contrail cirrus (57.4 mW m-2), CO2 (34.3 mW m-2), and NOx (17.5 mW m-2). Non-CO2 terms sum to yield a net positive (warming) ERF that accounts for more than half (66%) of the aviation net ERF in 2018. Using normalization to aviation fuel use, the contribution of global aviation in 2011 was calculated to be 3.5 (4.0, 3.4) % of the net anthropogenic ERF of 2290 (1130, 3330) mW m-2. Uncertainty distributions (5%, 95%) show that non-CO2 forcing terms contribute about 8 times more than CO2 to the uncertainty in the aviation net ERF in 2018. The best estimates of the ERFs from aviation aerosol-cloud interactions for soot and sulfate remain undetermined. CO2-warming-equivalent emissions based on global warming potentials (GWP* method) indicate that aviation emissions are currently warming the climate at approximately three times the rate of that associated with aviation CO2 emissions alone. CO2 and NOx aviation emissions and cloud effects remain a continued focus of anthropogenic climate change research and policy discussions.

Abstract
Minimizing the toxicity of radiotherapy is challenging. We investigated the effects of a phosphodiesterase type-5 inhibitor (PDE5I) on the urinary bladder after pelvic radiotherapy. Eight rats were assigned to each group (group 1: control; group 2: radiation; group 3: radiation plus PDE5I). Radiation dose was 10 Gy/one fraction. Udenafil (20 mg/kg, daily for 4 weeks) was administered in group 3. Cystometry was performed 4 weeks after treatment, followed by real-time PCR for PDE5, vascular endothelial growth factor (VEGF), and endothelial nitric oxide synthase (eNOS) mRNA, western blotting for PDE5, cyclic GMP-dependent protein kinase (PRKG), VEGF164, Akt, eNOS and NADPH oxidase (NOX)-2 proteins, and immunohistochemistry for eNOS. The expression of both VEGF mRNA and eNOS mRNA was higher in group 3 than in group 2. VEGF and eNOS protein expression improved with PDE5I treatment. Akt protein phosphorylation was higher in group 3 than in group 2, but NOX-2 protein expression was lower in group 3 than in group 2. Immunohistochemistry showed that the mean density of arterioles expressing eNOS was higher in group 3 than in group 2. Cystometry revealed that the intercontraction interval was remarkably longer in group 3 than in group 2 but that the maximal voiding pressure was higher in group 2 than in group 3. Daily treatment with a PDE5I after radiotherapy may prevent bladder storage dysfunction, potentially due to its effects on vasodilation and angiogenesis and through minimizing tissue oxidative damage by means of the VEGF/Akt/eNOS pathway.

Abstract
AIMS To investigate whether deep sedation for transrectal prostate biopsy could reduce anxiety and pain and enhance rebiopsy compliance. METHODS A two-centre prospective observation study was conducted under two different anaesthetic conditions: deep sedation with analgesia and local anaesthesia with lidocaine. A 12-core prostate biopsy was taken in all patients. Scores on a 0-10 visual analogue scale, the State-Trait Anxiety Inventory-X-1, the Beck Anxiety Inventory and a five-level Likert satisfaction scale were evaluated. Finally, all patients were asked about their willingness to undergo the same procedure again if necessary and whether they wanted to change the anaesthetic method (deep sedation to local anaesthesia or local to sedation) if a repeat procedure was required. RESULTS A total of 135 patients were included in this study, including 69 patients in the sedation group and 66 patients in the local group. Lower pain scores (P < .001) and higher satisfaction scores (P = .019) were observed in the sedation group than in the local group after the procedure. Anxiety scores in the sedation group were significantly decreased after the procedure, whereas those were not changed in the local group. The question regarding rebiopsy compliance tended to be more positive in the sedation than in the local group (73.9% vs 62.1%, respectively, P = .099). The proportion of patients who wanted to change their anaesthetic method was much higher in the local than in the sedation group (68.2% vs 11.6%, respectively, P < .001). CONCLUSION Deep sedation with analgesia during transrectal prostate biopsy could reduce pain and postprocedural anxiety and enhance rebiopsy compliance. Considering the psychological and oncological benefits, we strongly recommend inducing deep sedation during transrectal prostate biopsy.

Abstract
BACKGROUND After radiotherapy, the risk of hypogonadism increases, and the incidence of erectile dysfunction increases with time. AIM We investigated the effect of testosterone and a phosphodiesterase type 5 inhibitor (PDE5I) on erectile tissue after radiotherapy. METHODS 12 male Wistar rats were assigned to each of 5 groups (group C: control; group R: radiation; group RPT: radiation, testosterone, and a PDE5I; group RP: radiation and a PDE5I; and group RT: radiation and testosterone). A 12.5 Gy/fraction dose was administered to the rectum in groups R, RPT, RP, and RT. Udenafil (20 mg/kg) was administered daily via nasogastric tubes in group RPT and group RP for 4 weeks starting 1 day after radiotherapy. Testosterone enanthate (25 mg/kg, IM) was administered immediately after radiotherapy in group RT and group RPT. 6 rats from each group were used to evaluate endothelial nitric oxide synthase (eNOS), neuronal nitric oxide synthase (nNOS), and NOX2, and cavernosal pressure was evaluated in the other 6 rats in each group. OUTCOME Testosterone enhanced the effect of PDE5I on penile tissue after radiotherapy by amplifying the nitric oxide synthase activity. RESULTS eNOS mRNA expression increased in response to either testosterone replacement or PDE5I administration after radiotherapy. nNOS mRNA expression did not significantly increase in response to testosterone replacement, but testosterone significantly enhanced the effect of PDE5I on nNOS mRNA expression. Testosterone significantly amplified the effect of PDE5I on both eNOS and nNOS protein expression. Both testosterone and PDE5I reduced NOX2 protein expression. The intracavernosal pressure during electrical stimulation showed that testosterone alone did not significantly enhance erectile function. CLINICAL TRANSLATION Clinicians should consider both hypoxic tissue damage and hypogonadism during and after radiation, and the combination of testosterone and PDE5I could be more beneficial for preserving erectile tissue than either individual treatment. STRENGTHS & LIMITATIONS This study describes the role of testosterone in amplifying the effect of a PDE5I on pelvic radiotherapy-induced hypogonadism. However, we did not show the time-dependent effects of testosterone and PDE5I. CONCLUSIONS Despite the fact that the intracavernosal pressure during electrical stimulation did not significantly increase with testosterone replacement after radiotherapy, important changes in nitric oxide synthase activity and superoxide regulation might have amplifying effects on erectile tissue. Therefore, we recommend that physicians monitor testosterone levels and should not hesitate to combine testosterone and PDE5I in cases of radiation-induced hypogonadism if testosterone replacement is not contraindicated.

Abstract
Background To identify the risk factors for severe bleeding requiring angioembolization among patients who received transfusions after PCNL, particularly those who underwent anatomically incorrect renal puncture. Methods A total of 53 patients, who received transfusions after PCNL and simultaneously had a postoperative CT scan performed between November 2009 and May 2019 at two teaching hospitals, were retrospectively reviewed. The patients were divided into two groups: those who underwent angioembolization and those who did not. Patient, stone and procedural factors were compared between the two groups. Puncture correctness was evaluated using postoperative CT scans. Puncture was defined as being a correct puncture if the fornix or papilla of the posterior calyx was punctured and the trajectory of the tract was within 20 degrees posterior to the frontal plane of the kidney (i.e., within Brödel’s line). Results 21 patients underwent angioembolization after PCNL. Incorrect puncture was seen in 14/21 (66.7%) patients who underwent angioembolization after PCNL, whereas it was seen in 11/32 (34.4%) patients who did not undergo angioembolization (p = 0.021). On multivariable regression analysis, puncture correctness was found to be the only significant factor, with an OR of 3.818, 95% CI of 1.192–12.231 and p value of 0.024. Conclusions Incorrect renal puncture was related to severe bleeding requiring angioembolization after PCNL. Our results emphasize the importance of the basic principle of renal puncture for PCNL.

Abstract
Purpose We aimed to evaluate the association between nocturnal frequency and erectile dysfunction in patients with benign prostatic obstruction. Materials and Methods To evaluate the association, we simultaneous evaluated urodynamic study, prostate ultrasound, nocturnal tumescence test (nocturnal penile tumescence) for sleep-related erection (SRE) and two questionnaires, international prostate symptom score (IPSS) and 5-item version of the international index of erectile function (IIEF-5). Patients with hypogonadism or nocturnal polyuria were excluded. Results Forty-six patients were registered over 4 years. The mean age, prostate size, IPSS score, and IIEF-5 score were 67.65±5.51 years, 65.10±22.12 mL, 24.67±7.89, and 9.50±7.01, respectively. Among the IPSS subscores, nocturia was most significantly related to the total IIEF-5 score (p<0.001). More severe nocturia was associated with less frequent SRE (p=0.003) and shorter total duration of SRE (p=0.002), which in turn elucidated that nocturia was significantly related to the total amount of rigidity signals (rigidity activity unit, RAU) or tumescence signals (tumescence activity unit, TAU). Among objective urodynamic parameters, bladder compliance also correlated to RAU and TAU. Individual subjective erectile function (IIEF-5) was significantly related to both RAU and TAU. Conclusions Sleep fragmentation due to benign prostate obstruction related nocturnal frequency caused by reduced bladder compliance could decrease the frequency and duration of SRE, which decreases the total amount of SRE and reflects the patient's relevant erectile function.

Abstract
PURPOSE There is conflict of evidence regarding whether absence of hydronephrosis is a risk factor for bleeding in percutaneous nephrolithotomy (PNL). Moreover, among the stone complexity scoring system used for PNL (Guy's stone score, the S.T.O.N.E. nephrometry and the CROES nomogram), only the S.T.O.N.E. nephrometry score incorporates hydronephrosis as a risk factor. Therefore, this study aimed to compare perioperative outcomes according to the presence or absence of hydronephrosis in percutaneous nephrolithotomy (PCNL) patients and to investigate whether absence of hydronephrosis is a risk factor for blood transfusion rate. MATERIALS AND METHODS 281 patients who had undergone PCNL between December 2009 and April 2017 were divided according to the absence or presence of hydronephrosis (group I and group II, respectively). Perioperative outcomes were compared between the two groups. A multivariable regression analysis was performed to investigate whether hydronephrosis was a risk factor for blood transfusion rate. RESULTS Patients without hydronephrosis showed significantly longer operation time and admission period, lower stone-free rate and higher blood transfusion rate compared to patients with hydronephrosis (p < 0.05, p = 0.002, p = 0.011, and p < 0.05, respectively). Multivariate logistic regression analysis showed that hydronephrosis was a significant risk factor for blood transfusion (OR, 95% CI and p value was 0.353, 0.163-0.761 and 0.008, respectively). CONCLUSION Based on the results of the current study, we found that absence of hydronephrosis was a significant risk factor for blood transfusion in conventional PCNL.

Abstract
OBJECTIVE The present study was aimed to investigate (1) whether urodynamic factors are responsible for kidney damage in patients with bladder outlet obstruction (BOO) and (2) whether transurethral prostate surgery for BOO can alleviate the damage to the kidneys. METHODS This prospective observational study involved men aged 50-80 years. Prostate size and urodynamic test were performed during screening period. Laboratory tests to measure the glomerular filtration rate, the urinary protein to creatinine ratio and dipstick urinalysis were performed before and 6 months after the transurethral prostate surgery. RESULTS Sixty-seven patients completed the laboratory study among a hundred enrolled patients with urodynamically proven BOO. Among the urodynamic parameters, only low bladder compliance (lower than 60 mL/cmH2O) was associated with clinically significant proteinuria (p < 0.001). Transurethral prostate surgery significantly improved proteinuria (p = 0.007), especially in patients with low bladder compliance (p = 0.004), and subsequently decreased the risk grade of CKD progression (p < 0.001). CONCLUSIONS Low bladder compliance in patients with BOO may be a risk factor for kidney damage. Transurethral prostate surgery to relieve BOO could be a preventive method against CKD progression in patients with low bladder compliance.

Abstract
In this work, the extraordinary properties of CuO addition on the morphology and supercapacitive performance of Mn2O3 electrodes were demonstrated. Concisely, CuO/Mn2O3 thin films were prepared by an easy and inexpensive successive ionic layer adsorption and reaction (SILAR) method. The prepared thin films were characterized by various sophisticated physiochemical systems. The results demonstrated formation of Mn2O3 thin films with noteworthy morphological alteration upon introduction of CuO. Furthermore, a significant effect of CuO introduction was observed on the electrocatalytic properties of the nanostructured Mn2O3 electrodes. At 3% CuO doping, the Mn2O3 electrodes displayed the maximum specific capacitance owing to formation of nanoplate-like structures. The enhanced specific capacitance attained for 3% CuO doping in the Mn2O3 electrode was 500 F/g at 5 mV/s in a 3 M KOH electrolyte. All results confirmed the plausible potential of the CuO/Mn2O3 electrode for supercapacitor applications.

Abstract
Abstract
Background
The aim was to characterize end-of-life care in patients who have had a leg amputated for peripheral artery disease (PAD) or diabetes.
Methods
This was a population-based retrospective cohort study of patients with PAD or diabetes who died in Ontario, Canada, between 2011 and 2017. Those who had a leg amputation within 3 years of death were compared with a control cohort of deceased patients with PAD or diabetes, but without leg amputation. The patients were identified from linked health records within the single-payer healthcare system. Place and cause of death, as well as health services and costs within 90 days of death, were compared between the amputee and control cohorts. Among amputees, multivariable regression models were used to characterize the association between receipt of home palliative care and in-hospital death, as well as time spent in hospital at the end of life.
Results
Compared with 213 300 controls, 3113 amputees were less likely to die at home (15·5 versus 24·9 per cent; P < 0·001) and spent a greater number of their last 90 days of life in hospital (median 19 versus 8 days; P < 0·001). Amputees also had higher end-of-life healthcare costs across all sectors. However, receipt of palliative care was less frequent among amputees than controls (inpatient: 13·4 versus 16·8 per cent, P < 0·001; home: 14·5 versus 23·8 per cent, P < 0·001). Among amputees, receipt of home palliative care was associated with a lower likelihood of in-hospital death (odds ratio 0·49, 95 per cent c.i. 0·40 to 0·60) and fewer days in hospital (rate ratio 0·84, 0·76 to 0·93).
Conclusion
Palliative care is underused after amputation in patients with PAD or diabetes, and could contribute to reducing in-hospital death and time spent in hospital at the end of life.

Abstract
Abstract
Background
There has been increased attention on reducing hospital readmission rates. However, little is known about any difference in readmission rates in heart failure by sex, although evidence exists demonstrating differences in the etiology of heart failure. As a result, strategies to optimize readmission reduction programs and care strategies for women and men remain unclear.
Purpose
(1) To identify studies examining readmission rates according to sex, and (2) to provide a qualitative overview of possible considerations for the impact of sex or gender.
Methods
A scoping protocol was developed using the Arksey and O'Malley framework and the Joanna Briggs Institute methodology. Our search strategy was reviewed according to the peer-review of electronic search strategy (PRESS) checklist. Full text articles published between 2002 and 2017 and drawn from multiple databases (i.e. MEDLINE, EMBASE), grey literature (i.e. National Technical Information, Duck Duck Go), and experts were consulted for additional articles. Screening criteria were established a priori. Once an acceptable inter-rater agreement was established at 80% by two independent reviewers, articles were screened for potential eligibility. A descriptive analytical method was employed to chart primary research articles. Articles were considered relevant if the cohort consisted of adult heart failure patients who were readmitted after an index hospitalization and a sex/gender-based analysis was performed.
Results
The literature search yielded 5887 articles, of which 746 underwent full text assessment for eligibility. Of 164 eligible articles, 34 studies addressed the primary outcome, 103 studies considered sex differences as a secondary outcome and 25 studies included disaggregated data for sex but no subsequent interaction was reported. Good inter-rater agreement was reached: 83% for title and abstract screening; 88% for full text review; kappa: 0.69 (95% CI: 0.526–0.851). Twelve of 34 studies included for the primary outcome reported higher readmission rates for men compared to five studies reporting higher readmission rates for women. However, there were differential readmission rates that were dependent on duration of follow-up. Women were more likely to experience higher readmission rates than men when time to event was less than one year. Readmission rates for men were higher when follow-up was longer than one year.
Conclusion
Sex differences in readmission rates were dependent on follow up time. Most studies used composite outcomes and had short times to event, which may mask underlying effects of sex on readmission.

Abstract
Purpose To study the sexual behavior and status of sexually transmitted urethritis (STU) in the elderly population of South Korea. Materials and Methods Congregating places for elderly population, which were selected on the expected risk of sexually transmitted infections, were visited to study their sexual behavior, awareness on sexually transmitted diseases (STDs), and STU status using a specially developed survey and urine polymerase chain reaction (PCR) test. In addition, analysis of the Health Insurance Review & Assessment Service (HIRA) database was done to study the nationwide status and trends of STU of the elderly population. Results The study found that approximately 42% of elderly South Koreans were sexually active. Elderlies in the high-risk group showed a higher percentage of multiple sexual partners and prostitution than elderlies in the low-risk group. Only 3% and 14% in the low-risk group and high-risk group used condoms, showing a very low rate of condom use. Both the urine PCR results and HIRA database analysis showed that the prevalence of STU was not high and it remained stable in recent years, implying that currently, STU is not a significant burden on public health in the elderly population of South Korea. Conclusions The current study presented the sexual behavior in the elderly population of South Korea, as well as the recent prevalence and trend of STU in the elderly population. These results may be used as baseline data for future study, education, prevention and public campaign plan for STDs in the elderly population.

Abstract
Abstract
Purpose: To evaluate the treatment outcomes of radiotherapy (RT) for breast cancer with ipsilateral supraclavicular (SCL) and/or internal mammary (IMN) lymph node involvement.
Methods: A total of 353 patients from 11 institutions were included. One hundred and thirty-six patients had SCL involvement, 148 had IMN involvement, and 69 had both. All patients received neoadjvant systemic therapy followed by breast conserving surgery or mastectomy, and postoperative RT to whole breast/chest wall. As for regional lymph node irradiation, SCL RT was given to 344 patients, and IMN RT to 236 patients. The median RT dose was 50.4 Gy.
Results: The median follow-up duration was 61 months (range, 7-173). In-field progression was present in SCL (n=20) and/or IMN (n=7). The 5-year disease-free survival (DFS) and overall survival rates were 57.8% and 75.1%, respectively. On multivariate analysis, both SCL/IMN involvement, number of axillary lymph node ≥4, triple negative subtype, and mastectomy were significant adverse prognosticators for DFS (p = 0.022, 0.001, 0.001, and 0.004, respectively). Regarding the impact of regional nodal irradiation, SCL RT dose ≥54 Gy was not associated with DFS (5-yr rate, 52.9% vs. 50.9%, p = 0.696) in SCL-involved patients, and the receipt of IMN RT was not associated with DFS (5-yr rate, 56.1% vs. 78.1%, p = 0.099) in IMN-involved patients.
Conclusion: Neoadjuvant chemotherapy followed by surgery and postoperative RT achieved an acceptable in-field regional control rate in patients with SCL and/or IMN involvement. However, a higher RT dose to SCL or IMN RT was not associated with the improved DFS in these patients.

Abstract
BACKGROUND Detrusor sphincter dyssynergia, involuntary detrusor contractions (IDCs), and poor bladder compliance are common urodynamic findings in cervical spondylotic myelopathy (CSM). There is little information regarding the role of a urodynamic study after decompression surgery for CSM. METHODS Urodynamic study was performed before and 6 months after decompression of CSM. Japanese Orthopaedic Association score for cervical myelopathy and Neck Disability Index functional score were applied. International Prostate Symptom Score was applied in male patients, and 6-item Urogenital Distress Inventory was applied in female patients. RESULTS Mean patient age was 61.3 years. Final follow-up was obtained in 17 of 32 patients. Neurogenic bladder was confirmed in 11 (64.7%) patients, with 7 patients having poor bladder compliance, 3 patients having IDCs, and 6 patients having detrusor sphincter dyssynergia. Poor bladder compliance was normalized in 4 of 7 patients. IDCs disappeared in 2 (phasic IDCs) of 3 patients and improved in 1 (terminal IDC) patient. Detrusor sphincter dyssynergia markedly improved in 4 of 6 patients. Bladder compliance in 17 patients was 45.52 ± 23.71 before decompression surgery and 77.07 ± 39.85 after decompression surgery (P = 0.004). Both Japanese Orthopaedic Association and Neck Disability Index scores improved (P = 0.007 and P = 0.001, respectively). International Prostate Symptom Score and 6-item Urogenital Distress Inventory were not changed 6 months after surgery. CONCLUSIONS Neurogenic bladder could be partially controlled in patients with CSM after surgical decompression. The neurogenic component in the urodynamic study findings varied. Depending on the findings, further appropriate urologic treatments after neurologic decompression surgery should be considered.

Abstract
In complicated urinary tract infection with ureteral calculi, urinary diversion is inevitable. So, stenting or percutaneous drainage can be an option. In hemodynamically unstable patients, percutaneous drainage is superior to ureteral stenting (1). Once acute infection is controlled, definite treatment of the stone is necessary. According to a guideline, semirigid ureteroscopy is recommended for lower and mid - ureter stone and flexible ureteroscopy for upper ureter stone (2). Semi - rigid ureteroscopy can migrate stone to kidney, especially in upper ureter stone, lowering stone free rate (3). Not only flexible ureteroscopy creates additional costs but also is barely available in developing countries (4, 5). So, the authors would like to introduce anterograde irrigation - assisted ureteroscopic lithotripsy in patients with percutaneous nephrostomy. Retrograde irrigation was connected and flowed minimally enough to secure visual field. Once stone is noted, another saline irrigation, which is placed above 40 cm over the patient is connected to nephrostomy. Retrograde irrigation is disconnected from ureteroscope and the previous connected channel on ureteroscope is opened. Actual pressure detected by barometer from the opened channel of ureteroscope is usually about 30 cmH2 O while anterograde irrigation is administered in maximal flow, which means fully opened anterograde irrigation is not hazardous to kidney. There was no complication in 17 patients submitted to this method. Video shows advantages of our practice: clear visual field; reduced risk of stone migration into kidney; induced spontaneous passage of fragments without using instrumentation; and decreased operation time. In short, most of surgeons, even unexperienced, can perform an excellent procedure with less time consuming using our method.

Abstract
Urinary tract infections (UTIs) caused by Escherichia coli (E. coli) are the most common types of infections in women. The antibiotic resistance of E. coli is increasing rapidly, causing physicians to hesitate when selecting oral antibiotics. In this review, our objective is to ensure that clinicians understand the current seriousness of antibiotic-resistant E. coli, the mechanisms by which resistance is selected for, and methods that can be used to prevent antibiotic resistance.

Abstract
Enamel makes up the outermost layer of the crown and its hardness protects other dental tissues from various stimuli. Enamel cannot be regenerated once damaged because ameloblasts are lost during the tooth eruption. Since the ameloblast differentiation mechanism is still unknown, further research is essential for developing treatments for defective or damaged enamel. Previously, we have reported that osteoblast differentiation and bone formation were regulated through the runt-related transcription factor 2 (Runx2)-nuclear factor 1-C (Nfic)-osterix (Osx) pathway where Nfic directly controls Osx expression. This pathway regulates odontoblast differentiation and dentin formation as well. The aim of this study was to investigate if the same pathway is applicable for ameloblast differentiation. Structural enamel defects with disorganized ameloblasts and decreased proliferation activity of the cervical loop were observed in Nfic-/- mice incisors. Expression of the ameloblast differentiation markers was also downregulated significantly in Nfic-/- mice. Real-time PCR analyses suggested that Runx2, Nfic, and Osx regulate the expression of ameloblast differentiation markers, where Runx2 is upstream of Nfic, and Nfic controls Osx expression. Therefore, we suggest the Runx2-Nfic-Osx pathway as one of the key factors that regulate ameloblast differentiation.

Abstract
Recent wearable devices offer portable monitoring of biopotentials, heart rate, or physical activity, allowing for active management of human health and wellness. Such systems can be inserted in the oral cavity for measuring food intake in regard to controlling eating behavior, directly related to diseases such as hypertension, diabetes, and obesity. However, existing devices using plastic circuit boards and rigid sensors are not ideal for oral insertion. A user-comfortable system for the oral cavity requires an ultrathin, low-profile, and soft electronic platform along with miniaturized sensors. Here, we introduce a stretchable hybrid electronic system that has an exceptionally small form factor, enabling a long-range wireless monitoring of sodium intake. Computational study of flexible mechanics and soft materials provides fundamental aspects of key design factors for a tissue-friendly configuration, incorporating a stretchable circuit and sensor. Analytical calculation and experimental study enables reliable wireless circuitry that accommodates dynamic mechanical stress. Systematic in vitro modeling characterizes the functionality of a sodium sensor in the electronics. In vivo demonstration with human subjects captures the device feasibility for real-time quantification of sodium intake, which can be used to manage hypertension.

Abstract
This study investigated the prevalence and antibiotic resistance of Ureaplasma spp. and Mycoplasma hominis isolated from asymptomatic individuals in Korea. Endocervical swabs from women and urine from men, from a total of 5,781 asymptomatic individuals, were analyzed using a Mycoplasma IST2 Kit. Of the 4,825 specimens tested from females, 486 (10.1%) were positive culture. In these positive specimens, 437 (9.1%) were positive only for Ureaplasma spp., 17 (0.4%) were positive only for M. hominis, and 32 (0.7%) were positive for both Ureaplasma spp. and M. hominis. In males, of the 956 tested specimens, only 4 (0.42%) were positive for Ureaplasma spp. and no M. hominis colonization was identified. In antimicrobial susceptibility tests, more than 93.2% of both M. hominis and Ureaplasma spp. was susceptible to tetracycline, doxycycline, josamycin, and pristinamycin. However, M. hominis isolates were found to be highly resistant to erythromycin, azithromycin, and clarithromycin (82.4%, 70.6%, and 76.5%, respectively). Ofloxacin and ciprofloxacin, which have recently exhibited increasing resistance rates, showed rates of 17.7% and 35.3%, respectively, in M. hominis, and 50.6% and 27.4%, respectively, in Ureaplasma spp. In conclusion, accurate antimicrobial susceptibility tests of the genital mycoplasmas should be conducted for each case to select the appropriate antibiotics. Fluoroquinolone-based drugs should be avoided in the initial treatment of urogenital mycoplasmas because of the increasing rate of resistance to quinolones, although the susceptibility to tetracycline remains high in Korea.

Abstract
In this paper, we chemically synthesized interconnected nanoflake-like CdS thin films for photoelectrochemical solar cell applications and subsequently irradiated them with electron beam irradiation at various doses of irradiation. The as-synthesized and irradiated samples were characterized by means of X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), and electrochemical measurements. XRD and XPS results confirmed the formation of CdS with a hexagonal crystal structure. FE-SEM and HR-TEM studies confirmed the photoelectrochemical performance, which was dependent on the surface morphology. The calculated values for efficiency demonstrated an outstanding photoelectrochemical performance with a fill factor of 0.38 and efficiency of 3.06% at 30 kGy. The high photoelectrochemical performance may be due to the interconnected nanoflake-like nanostructure and higher active surface area of the CdS samples. These results show that the electron beam irradiation is capable as an electrode for photoelectrochemical solar cells.

Abstract
This study aimed to determine the role of asymptomatic bacterial sexually transmitted infections (STIs), such as Chlamydia trachomatis (Ct), Mycoplasma genitalium (Mg), Mycoplasma hominis (Mh), and Ureaplasma urealyticum (Uu) in human papillomavirus (HPV) infection. In total, 264 asymptomatic outpatients aged between 21 and 80 years were prospectively enrolled in this study during routine gynecological screening tests. Specimens collected with a Cervex Brush were routinely analyzed with the Hybrid Capture 2 assay for HPV. Simultaneously, a specimen obtained with an endocervical swab was used to detect Ct and Mg with a monoplex real-time polymerase chain reaction (PCR) and to confirm Mh and Uu with a Mycoplasma IST 2 kit. The detection rates (%) of HPV, Ct, Mg, Mh, and Uu were 82/264 (31.1), 6/264 (2.3), 5/264 (1.9), 16/264 (6.1), and 95/264 (36.0), respectively. Of 95 Uu, 32 (33.7%) showed high density colonization (HDC, ≥104 color-changing units/mL). HDC-Uu was significantly associated with HPV infection (p=0.014, chi-square test). Mg infection and Mh infection were not associated with HPV infection (p=0.981 and p=0.931, chi-square test). Age was not associated with HPV infection or bacterial infection. Our data suggested that asymptomatic HDC-Uu was closely associated with HPV infection. Therefore, simultaneous evaluation for Uu and HPV should be performed during gynecological screening, even in asymptomatic individuals.

Abstract
Background The relative efficacy of interventions for primary prevention of anthracycline-associated cardiotoxicity is unknown. Methods We conducted a systematic review of randomized controlled trials for primary prevention of anthracycline-associated cardiotoxicity in adult cancer patients. We used hierarchal outcome definitions in the following order of priority: (1) composite of heart failure or decline in left ventricular ejection fraction, (2) decline in ejection fraction, or (3) heart failure. Data were analyzed using a Bayesian network meta-analysis with random effects. Results A total of 16 trials reported cardiotoxicity as a dichotomous outcome among 1918 patients, evaluating dexrazoxane, angiotensin antagonists, beta-blockers, combination angiotensin antagonists and beta-blockers, statins, Co-enzyme Q-10, prenylamine, and N-acetylcysteine. Compared with control, dexrazoxane reduced cardiotoxicity with a pooled odds ratio (OR) of 0.26 (95% credible interval [CrI] 0.11-0.74) and had the highest probability (33%) of being most effective. No other agent was demonstrably better than placebo. Angiotensin antagonists had an 84% probability of being most effective in a sensitivity analysis excluding one outlying study (OR 0.06 [95% CrI 0.01- 0.24]). When the outcome was restricted to heart failure, dexrazoxane was associated with an OR of 0.12 (95% CrI 0.06-0.23) relative to control and had 58% probability of being most effective, while angiotensin antagonists had an OR of 0.18 (95% CrI 0.05-0.55). Available data suggested that dexrazoxane and angiotensin antagonists did not affect malignancy response rate or risk of death. Conclusion Moderate quality data suggest that dexrazoxane, and low quality data suggest angiotensin antagonists, are likely to be effective for cardiotoxicity prevention.

Abstract
Introduction and Objectives: Nephrectomy is occasionally required due to severe extra-renal symptom(s) such as dyspepsia in patients with autosomal dominant polycystic kidney disease (ADPKD), wherein a large incision is required for specimen extraction. Considering problems such as hernia, wound dehiscence, incidental bowel injury, and poor wound healing in such cases, we would like to present retroperitoneoscopic nephrectomy and morcellation of the kidney as an ideal minimally invasive technique. Materials and Methods: A 53-year-old man who was undergoing hemodialysis for 6 years due to ADPKD visited the outpatient clinic with a complaint of severe dyspepsia. Kidney length (long axis) was greater than 28 cm. Nephrectomy was the last option to restore his digestive system which was mechanically compressed by an extremely enlarged polycystic kidney. Retroperitoneoscopic nephrectomy was performed using 3 ports. When it was difficult to continue the dissection due to limited space, large cysts were punctured and aspirated to create additional working space. The specimen was extracted by a morcellator (KARL STORZ GmbH & Co. KG, Tuttlingen, Germany) introduced through a 12mm trocar. Results: Operating time was 230 minutes, wherein the time for morcellation was 52 minutes. No additional incision was required for specimen extraction. He underwent hemodialysis on post-operative days #1 and #3. He was discharged on post-operative day #4 (total hospital stay was 6 days.). Dyspepsia dramatically improved without post-operative complications. Conclusions: Retroperitoneoscopic nephrectomy is feasible for treatment of ADPKD. By using a morcellator, an additional incision is not required and wound complication would not occur.

Abstract
Diaphragmatic eventration is an uncommon condition, usually discovered incidentally in asymptomatic patients. Even in symptomatic patients, the diagnosis can be challenging and should be considered among the differential diagnoses of diaphragmatic hernia. The correct diagnosis can often only be made in surgery. We describe the case of a 31-year-old patient with diaphragmatic eventration that was misdiagnosed as a recurrent congenital diaphragmatic hernia and review the corresponding literature.

Abstract
There are more than 3 million people in the world whose mobility relies on wheelchairs. Recent advancement on engineering technology enables more intuitive, easy-to-use rehabilitation systems. A human-machine interface that uses non-invasive, electrophysiological signals can allow a systematic interaction between human and devices; for example, eye movement-based wheelchair control. However, the existing machine-interface platforms are obtrusive, uncomfortable, and often cause skin irritations as they require a metal electrode affixed to the skin with a gel and acrylic pad. Here, we introduce a bioelectronic system that makes dry, conformal contact to the skin. The mechanically comfortable sensor records high-fidelity electrooculograms, comparable to the conventional gel electrode. Quantitative signal analysis and infrared thermographs show the advantages of the soft biosensor for an ergonomic human-machine interface. A classification algorithm with an optimized set of features shows the accuracy of 94% with five eye movements. A Bluetooth-enabled system incorporating the soft bioelectronics demonstrates a precise, hands-free control of a robotic wheelchair via electrooculograms.

Abstract
INTRODUCTION Narrow working space is a major problem to overcome during retroperitoneoscopic ureterolithotomy. We evaluated initial 5 years experience of retroperitoneoscopic ureterolithotomy for large impacted upper ureteral calculi. PATIENTS AND METHODS Between January 2011 and December 2015, a total of 37 consecutive patients were evaluated. A 12-mm camera port at middle of midaxillary line and two 5-mm working ports in posterior axillary line were created. The stone was extracted through the site of camera trocar. A Double-J catheter (DJC) was placed antegradely by four steps (elevating of the proximal shaft, introducing the end of curl, advancing, and twisting) during retroperitoneoscopic ureterolithotomy. A knotless unidirectional barbed suture was applied to the incision site of the ureter in all cases. All patients were followed up at 2 weeks after discharge to remove a DJC and at 6 weeks after discharge to evaluate urinary drainage with intravenous urography. RESULTS The mean ± standard deviation for age (years), body mass index (kg/m2), stone size (mm), and postoperative hospital days were 57.9 ± 13.3, 24.6 ± 4.5, 15.5 ± 4.0, and 3.2 ± 1.2, respectively. Stones were successively removed without critical complications such as ureteral stricture in all cases. Total operation time, the time for placing a DJC, and ureteral suturing time at initial three trials were more than 150 minutes, more than 30 minutes, and about 15 minutes, respectively; however, they were about 60 minutes, less than 10 minutes, and about 5 minutes, respectively, in 25 case experiences. CONCLUSIONS Retroperitoneoscopic ureterolithotomy is a safe and excellent alternative for large impacted upper ureter stone. When performing retroperitoneoscopic ureterolithotomy in the narrow space, our step by step methods, including working port creation, DJC placement, and suturing, will be helpful for surgeons to learn the procedure easily.

Abstract
Non-Hodgkin lymphoma involving the esophagus is very rare. Only a few cases have been reported in the English literature to date, and it accounts for less than 1% of all cases of gastrointestinal lymphoma. As this malignancy manifests as a submucosal tumor, pathological diagnosis by using a simple endoscopic biopsy alone is difficult. Therefore, surgical biopsy, endoscopic mucosal resection, and endoscopic ultrasound-guided fine-needle aspiration have been used in most cases. Herein, we report a case of esophageal mucosa-associated lymphoid tissue lymphoma in a 49-year-old man, which involved the use of a stacked forceps biopsy to obtain adequate samples for pathological analysis; the use of the stacked forceps biopsy method is unlike those used in previous cases. The patient received cyclophosphamide, vincristine, and prednisolone chemotherapy; he achieved a complete response. In addition, we review the literature relevant to this case.

Abstract
A DNA nanostructure bearing a “Shuriken” shape is designed to deliver, protect and activate microRNA-145 functionality in human colorectal cancer cells. This novel DNA nanostructure enabled therapeutic platform greatly suppresses cancer cell proliferation and tumor growth.
Tumor suppressive microRNAs are potent molecules that might cure cancer, one day. Despite the many advanced strategies for delivery of these microRNAs to the cell, there are few therapeutic microRNAs in clinical use. Progress in microRNA bioapplications is hindered by a high vulnerability of exogeneous microRNA molecules to RNase degradation that occurs in extra- and intracellular physiological conditions. In this proof-of-concept study, we use a programmable self-assembled DNA nanostructure bearing a “shuriken” shape to not only deliver but more importantly protect a tumor suppressive microRNA-145 for a sufficiently long time to exert its therapeutic effect in human colorectal cancer cells. Our DNA nanostructure harbored complementary sequences that can hybridize with the microRNA cargo. This brings the microRNA–DNA duplex very close to the core structure such that the microRNA cargo becomes sterically shielded from RNase's degradative activity. Our novel DNA nanostructure based protector concept removes the degradative bottleneck that may plague other nucleic acid delivery strategies and presents a new paradigm towards exploiting these microRNAs for anti-cancer therapy.
