Abstract
Objective: To analyze the influencing factors of lung function in pneumoconiosis patients, and to provide reference for clinical treatment. Methods: From July 2020 to December 2020, a questionnaire survey was conducted on pneumoconiosis patients in the jurisdiction by using the "Guangdong Province Occupational Disease Prevention and Control Institute" questionnaire, and the relevant items of patients were examined. The rate of counting data is expressed, and the measurement data is expressed by mean and standard deviation. Chi-square test was used for comparison between groups, trend chi-square test was used for trend analysis of ordered classified data. Multivariate analysis was carried out with binary logistic regression model. Results: A total of 1409 pneumoconiosis patients were enrolled. The abnormal rate of lung function in pneumoconiosis patients was 68.77%. The results of trend Chi-square test showed that the abnormal rate of lung function increased with the age of exposure to dust in different age groups (Chi Sqnare Trend=64.12、8.49、24.20, P<0.05) . In univariate analysis, there were statistical significance in different dust exposure age, working age, pneumoconiosis stage, complications and occupational pneumoconiosis diseases (P<0.05) . Multiple logistic regression results showed that age of exposure to dust, years of service, stage of pneumoconiosis and complications were the main influencing factors of lung function in pneumoconiosis patients (P<0.05) . Compared with patients aged 0-30 years, patients aged 50-70 years and older had a higher rate of abnormal lung function (OR=2.16, 95%CI: 1.12~4.16; OR=4.82, 95%CI: 2.05~11.35, all P<0.05) ; Compared with patients with 0~20 years of service, patients with 20~30 years of service and more than 30 years of service had a higher rate of abnormal lung function (OR=1.58, 95%CI: 1.10~2.25; OR=1.63, 95%CI: 1.28~2.40, P<0.05) ; Compared with stage Ⅰ patients, Stage Ⅱ and Stage Ⅲ patients had a higher rate of abnormal lung function (OR=1.62, 95%CI: 1.20~2.17; OR=2.23, 95%CI: 1.40~3.55, all P<0.05) ; Compared with patients without comorbidities, patients with comorbidities had a higher rate of abnormal lung function (OR=1.68, 95%CI: 1.20~2.38, P<0.05) . Conclusion: The factors such as age of exposure to dust, working age, stage of pneumoconiosis and complications may be the influencing factors of lung function in pneumoconiosis patients.

Abstract
Objective: To compare the efficacy and safety of trabeculotome tunnelling trabeculoplasty and gonioscopy-assisted transluminal trabeculotomy (GATT) in the treatment of open-angle glaucoma. Methods: A prospective randomized controlled study. The patients with open-angle glaucoma diagnosed in the ophthalmology center of Beijing Tongren Hospital affiliated to Capital Medical University from January to July 2022 were collected and divided into GATT group (undergoing GATT) and 3T group (undergoing 3T operation) using a random number table. Intraocular pressure (IOP) was recorded for both groups at 1 day, 1 week, 1 month, and 3 months after the operation, and the types and quantities of anti-glaucoma drugs used, postoperative complications, and surgical success rate were compared. Normal distribution measurement data were analyzed using independent sample t-tests, non-normal distribution measurement data were analyzed using non-parametric tests, and counting data were analyzed using chi-square tests. Results: This study included 35 patients (43 eyes), consisting of 27 males and 8 females, with an average age of (43.0±14.3) years. There were 21 patients (23 eyes) in the GATT group and 19 patients (20 eyes) in the 3T group. The maximum IOP without anti-glaucoma drugs before surgery, the highest IOP with the maximum number of anti-glaucoma drugs, and the IOP at 3 months after surgery in the GATT group were (33.5±9.1), (22.2±6.1), and (16.0±3.1) mmHg (1 mmHg=0.133 kPa), respectively. The corresponding values for the 3T group were (35.2±7.8), (21.5±6.8), and (16.1±2.0) mmHg. After surgery, the IOP in both groups was lower than before surgery, with a statistically significant difference (P<0.05) and no significant difference between the two groups (P>0.05). In the 3 months following surgery, 13 eyes in the GATT group and 11 eyes in the 3T group received more than two types of anti-glaucoma drugs, with no significant difference between the two groups (P>0.05). Three months after surgery, the complete and conditional success rates of the GATT group were 14/18 and 16/18, respectively, and those of the 3T group were 12/15 and 13/15, respectively, with no significant difference between the two groups (P>0.05). The incidence of hyphema, ciliary detachment, and shallow anterior chamber 1 day after surgery was 91%(21/23), 35%(8/23), and 30%(7/23), respectively, in the GATT group and 55%(11/20), 5%(1/20), and 0 in the 3T group, with a statistically significant difference between the two groups (P<0.05). Conclusion: 3T and GATT have similar success rates in the treatment of open-angle glaucoma. However, compared with GATT, 3T has fewer complications and is considered to be safer.

A93 USEFULNESS OF A NOVEL SMARTPHONE APP IN GASTROINTESTINAL ENDOSCOPY TO TRACK PROCEDURE NUMBERS AND THERAPEUTIC INTERVENTIONS. J Can Assoc Gastroenterol 2022. [PMCID: PMC8859206 DOI: 10.1093/jcag/gwab049.092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/22/2022] Open
Abstract
Background Endoscopy teaching is an integral part of gastroenterology (GI) training. Though the number of completed endoscopic procedures does not equate competency, procedure tracking is useful for monitoring an individual’s learning progress. Currently, procedure tracking is typically done on an informal basis using paper or electronic spreadsheets. These methods are non-standardized and may not be shareable between trainees and their programs. Endostation is a smartphone app created by the University of Alberta Therapeutic Endoscopy Program to facilitate the tracking of endoscopic procedures. The app allows trainees to record the number of endoscopies and details such as cecal intubation (CI), ERCP cannulation, and therapeutic interventions. Data can be accessed by users via the app and website (www.endostation.ca), allowing for close monitoring of trainees’ learning progress. Aims Our primary objective was to evaluate the usefulness of the app for tracking the number of endoscopic procedures and therapeutic interventions. Our secondary objective was to evaluate the acquisition of endoscopy skills based on quality endoscopic parameters such as CI rate and ERCP cannulation rate. Methods One therapeutic endoscopy fellow and two GI residents were recruited for the study. Participants were asked to document their procedures over the study period (9-month for therapeutic endoscopy fellow, 12-month for GI residents). Total number of procedures was summed for each trainee. Acquisition of endoscopy skills was tracked by comparing success rates of CI and ERCP cannulation at different points within the study period. Results The therapeutic endoscopy fellow recorded 415 cannulation attempts, 209 sphincterotomies, 282 stone extractions, 71 plastic stent placements, and 37 metal stent placements. There was a significant difference in the cannulation success rate when comparing the 1st trimester and the 3rd trimester of the study period (68% vs 85%; p= 0.0012) (Fig 1). The two GI residents respectively recorded 335 and 170 colonoscopies plus 454 and 305 gastroscopies. Resident 1 recorded 58 polypectomies, 9 esophageal variceal banding, and 16 non-variceal hemostasis. Resident 2 recorded 17 polypectomies, 12 esophageal variceal banding, and 9 non-variceal hemostasis. The CI success rate was significantly higher for both residents when comparing the first 4 months of training vs the last 4 months [24% vs 88% for resident 1 (p=0.00001); 15% vs 42% for resident 2 (p= 0.001)] (Fig 1). Conclusions The smartphone app (Endostation) was a useful tool for endoscopic procedure tracking. Data from the app was useful in demonstrating improvement in CI rate and ERCP cannulation rate over the study period. ![]()

A206 GALLSTONE IMPACTION IN THE DESCENDING COLON WITH SUCCESSFUL ENDOSCOPIC REMOVAL. J Can Assoc Gastroenterol 2022. [PMCID: PMC8859216 DOI: 10.1093/jcag/gwab049.205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/14/2022] Open
Abstract
Abstract
Background
Gallstone impaction in the colon is a rare complication of cholelithiasis, typically because of gallstones migrating into the colon via a cholecystocolonic fistula. Gastrointestinal obstruction from gallstones only develops in 0.3–0.5% of patients with cholelithiasis and accounts for 0.095% of all mechanical bowel obstruction. Successful treatment has been described with endoscopic and surgical techniques.
Aims
This report aims to present a case of colonic obstruction from gallstone that was successfully treated endoscopically.
Methods
We conducted a retrospective chart review on one patient including assessing the history of presenting illness along with biochemical, radiographic, and endoscopic results. We then conducted a narrative literature review on this subject matter.
Results
An 85-year-old male with known cholelithiasis complicated by prior cholecystitis presented with a 2-day history of generalized abdominal pain. Computed tomography (CT) showed fistulisation between the gallbladder and hepatic flexure. Follow-up CT with rectal contrast showed lack of contrast beyond an impacted gallstone in the descending colon (Figure 1A, 1B). The patient was deemed a poor surgical candidate thus endoscopic gallstone extraction was attempted. With a pediatric colonoscope, the 41mm x 51mm gallstone was visualized 70cm from anal verge (1C). The stone was too large to be extracted en-block with snare or basket. Attempts to cut the stone at its surface with a polypectomy snare and other tools were unsuccessful because of the roundness and smoothness of the stone. Although we could chip away at the surface, we were unable to break the seal of the stone against the colon mucosa. We found the most effective method was tunneling through the stone’s centre using a closed rat-tooth forceps, then angling the tip of the scope and pulling the scope back to break off fragments from within. A polypectomy snare was used to further breakup larger fragments to prevent repeat impaction (1D). There was underlying diverticular disease and mild ischemic changes to the mucosa but no stricture. The patient did well post-procedure and was able to tolerate oral intake, pass flatus, and pass bowel movements. He was discharged 3 days later.
A recent systematic review found a total of 38 cases of gallstone obstruction of the colon. Majority of patients (73.6%) ultimately required surgical intervention. Overall mortality is 13.1%.
Conclusions
Gallstone impaction in the colon is uncommon with successful endoscopic treatment seldomly described. This report describes a rare complication of gallstone disease that was successfully treated with widely available endoscopic tools.

A Multi-Factorial Observational Study on Sequential Fecal Microbiota Transplant in Patients with Medically Refractory Clostridioides difficile Infection. Cells 2021; 10:cells10113234. [PMID: 34831456 PMCID: PMC8624539 DOI: 10.3390/cells10113234] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Revised: 11/15/2021] [Accepted: 11/17/2021] [Indexed: 12/11/2022] Open
Abstract
Fecal microbiota transplantation (FMT) is highly effective in recurrent Clostridioides difficile infection (CDI); increasing evidence supports FMT in severe or fulminant Clostridioides difficile infection (SFCDI). However, the multifactorial mechanisms that underpin the efficacy of FMT are not fully understood. Systems biology approaches using high-throughput technologies may help with mechanistic dissection of host-microbial interactions. Here, we have undertaken a deep phenomics study on four adults receiving sequential FMT for SFCDI, in which we performed a longitudinal, integrative analysis of multiple host factors and intestinal microbiome changes. Stool samples were profiled for changes in gut microbiota and metabolites and blood samples for alterations in targeted epigenomic, metabonomic, glycomic, immune proteomic, immunophenotyping, immune functional assays, and T-cell receptor (TCR) repertoires, respectively. We characterised temporal trajectories in gut microbial and host immunometabolic data sets in three responders and one non-responder to sequential FMT. A total of 562 features were used for analysis, of which 78 features were identified, which differed between the responders and the non-responder. The observed dynamic phenotypic changes may potentially suggest immunosenescent signals in the non-responder and may help to underpin the mechanisms accompanying successful FMT, although our study is limited by a small sample size and significant heterogeneity in patient baseline characteristics. Our multi-omics integrative longitudinal analytical approach extends the knowledge regarding mechanisms of efficacy of FMT and highlights preliminary novel signatures, which should be validated in larger studies.

Abstract
Objective: To study the correlation between occupational radiation exposure and chronic metabolic diseases. Methods: The status of chronic metabolic diseases of medical workers were compared in 5 hospitals in Hangzhou. As representatives of chronic metabolic diseases, diabetes and metabolic syndrome (MS) were compared in association with duration of radiation exposure. Results: Long-term ionizing radiation (IR) exposure was led to increased blood pressure, fasting blood glucose (FBG) , dyslipidemia, gallbladder disease, and MS. The years of radiation exposure was associated with lens opacity, gallstone and MS in men and gallbladder polyps in women. Radiation working more than 10 years is one of the independent risk factors for increased FBG and MS. Moreover, the risk of FBG increase in the group of radiation working more than 10 years was 3.052 times of that the non-exposed group, and the risk of MS occurrence was 4.132 times that of the non-exposed group. Conclusion: Long-term exposure to IR increases the risk of chronic metabolic diseases.

Incidence of Venous Thromboembolism and Safety of Perioperative Subcutaneous Heparin During Inflatable Penile Prosthesis Surgery. Urology 2021; 157:155-160. [PMID: 34411598 DOI: 10.1016/j.urology.2021.08.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 07/14/2021] [Accepted: 08/02/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To identify the incidence of venous thromboembolism (VTE) risk factors, postoperative VTE, and to assess the morbidity of perioperative pharmacologic VTE prophylaxis in men undergoing inflatable penile prosthesis (IPP) surgery. METHODS We retrospectively reviewed 215 patients undergoing IPP surgery between July 2017 and June 2019. Univariate and multivariate statistical analyzes were performed to assess pre-operative Caprini risk score and compare post-operative day 0 scrotal drain output, scrotal hematoma formation, and VTE in men who received subcutaneous heparin (SqH) vs those who did not receive SqH. RESULTS Of 215 IPP patients, 84% were classified as high or highest risk for VTE utilizing the Caprini risk score. A total of 119 (55%) received perioperative SqH with or without additional anti-thrombotics. Post-operative day 0 scrotal drain output was higher in those who received SqH compared to those who did not receive SqH, 99.9 mL vs 75.6 mL, respectively (P = .001). Minor scrotal hematomas occurred in similar rates in patients who received perioperative SqH vs those who did not, 3.8% vs 6.3%, respectively (P = .38). Similar results were found on subgroup analysis when eliminating patients who received SqH concurrently with other anti-thrombotics. The overall rate of postoperative VTE was 0.9%. No post-operative infections occurred. CONCLUSION Patients undergoing IPP surgery are at elevated risk for VTE. To our knowledge, this is the first study showing SqH use in the perioperative IPP surgery setting is safe when used in conjunction with a scrotal drain. Preoperative VTE risk stratification may be performed and can be used to guide clinical decision making regarding pharmacologic prophylaxis.

Abstract
Abstract
Background
Fecal microbiota transplantation (FMT) is the most effective therapy for recurrent C. difficile infection. Although studies using statistical modeling have shown FMT to be cost-effective, real-world data is lacking.
Aims
To assess the impact of FMT program on the healthcare cost of recurrent C. difficile infections using real-world data from Alberta’s public healthcare system.
Methods
C. difficile infection patients were identified through provincial laboratory database with positive C. difficile results in Edmonton, Alberta between 2009–16. If an initial positive test was followed by ≧2 positive tests within 183 days, an individual was categorized as recurrent C. difficile infection (RCDI). Otherwise, non-recurrent C. difficile infection (non-RCDI) was assigned. Since the Edmonton FMT program was established in 2013, patients were further divided into pre-FMT (2009–12) and post-FMT (2013–16) eras. This divided patients into four study groups as outlined in Table 1. Administrative data, including inpatient stays, ambulatory or emergency room visits, outpatient prescriptions, and physician billings, were extracted. A cost of $389 was assigned to each FMT procedure to account for cost of donor screening and sample preparation. A difference in differences (DID) approach, a tool which estimates the effect of a treatment by comparing outcome difference between treatment group and control group over time, was used to analyze the impact of FMT program on the cost of RCDI. Non-RCDI patients were used as control group to account for changes in treatment costs over time. Ordinary least squares regression, with log-transformed healthcare cost as the dependent variable, was used for the analysis.
Results
4717 non-RCDI and 548 RCDI patients were identified and divided into the 4 groups (Table 1). RCDI patients were significantly older than non-RCDI patients (71.13 vs 62.49; P < 0.001). After adjusting for differences in age, sex, and baseline healthcare utilization, cost for RCDI patients were significantly lower relative to costs for non-RCDI patients in the post-FMT era. Cost of non-RCDI increased by $5,300.08 between the pre- and post-FMT eras, while the cost of RCDI decreased by $7,654.92 in the same time frame (Table 2). FMT program was estimated to have saved $12,954 annually for RCDI patients at mean age, sex, and baseline cost of our overall sample.
Conclusions
Our data suggest that the healthcare cost of RCDI has decreased with the introduction of an FMT program.

Intraureteral indocyanine green augments ureteral identification and avoidance during complex robotic-assisted colorectal surgery. Colorectal Dis 2021; 23:718-723. [PMID: 33064915 DOI: 10.1111/codi.15407] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Revised: 08/25/2020] [Accepted: 10/03/2020] [Indexed: 02/08/2023]
Abstract
AIM Up to 10% of patients who undergo nonurological abdominopelvic operations suffer a ureteral injury. While preoperative ureteral stenting to facilitate identification of the ureter is common, it does not reduce the incidence of intraoperative ureteral injury and is not without risk. As we continue to broaden the application of minimally invasive surgical techniques, a new form of ureteral identification and avoidance that does not rely on tactile feedback is needed. We report our initial experience with intraureteral indocyanine green (ICG) for ureteral identification and avoidance during complex robotic-assisted colorectal surgery. METHOD Patients undergoing adjunctive ureteral identification during robotic-assisted colorectal surgery were prospectively identified. Each patient underwent intraureteral ICG administration using rigid cystoscopy (22 Fr). A 5-Fr open-ended ureteral catheter was inserted up to 20 cm and used to inject 5 ml of 2.5 mg/ml ICG as the catheter was withdrawn to the ureteral orifice. Intraureteral ICG was then detected using near-infrared laser fluorescence technology (Firefly®). RESULTS Successful ICG-enhanced ureteral identification and avoidance was performed in 15 of 16 (94%) patients undergoing robotic-assisted colorectal surgery. The median ICG instillation time was 11.5 min (range 4-21 min) and the median operative time with ICG visualization was 489 min (8 h 9 min) [range 268-738 min (4 h 28 min-12 h 18 min)]. No patient experienced intraoperative ureteral injury and there were no adverse sequelae or complications associated with intraureteral ICG administration. CONCLUSION Intraureteral ICG is a safe and effective method of intraoperative ureteral identification and avoidance during complex robotic-assisted colorectal surgery. Precise and prolonged ureteral visualization was achieved, allowing for long operative times compatible with complex robotic-assisted operations.

Abstract
Introduction: Rezūm water vapor thermal ablation is a new minimally invasive technique used to treat benign prostatic hyperplasia. Major advantages include minimal anesthesia and recovery time, low rate of sexual side effects, and durable clinical improvement. However, data are lacking regarding use of Rezūm in prostate glands >80 cc. Here we seek to examine the clinical outcomes of men with large prostate glands following Rezūm. Patients and Methods: We retrospectively reviewed patients who underwent Rezūm therapy at our institution since July 2017. Three-month postoperative outcomes were analyzed, including American Urological Association symptom score (AUASS), peak flow, and postvoid residual (PVR). Complications, including hematuria and urinary tract infections, were also assessed. All statistical analyses were conducted using RStudio 1.2.1335. Results: One hundred eighty-two patients undergoing Rezūm were identified, of whom 25.8% had prostate volume >80 cc. Mean gland volume in this group was 119 cc and 55.3% were catheter dependent. Following Rezūm, statistically significant improvement was seen in AUASS from 22 to 13.4 (p = 0.04) and PVR from 305 to 149 cc (0.05). Statistically significant improvement was seen in peak flow rate from 7.7 to 12.7 mL/second (p = 0.002). In a subset of catheter-dependent patients, the postoperative catheter-free rate was 83% for men with glands >80 cc, which was comparable with 88% in the smaller gland group. Postoperative complication rate was not significantly different between large or small glands. Conclusions: In our experience, Rezūm is efficacious in patients with glands >80 cc. Patients experience symptomatic and objective improvement in voiding parameters that is comparable with patients with glands smaller than 80 cc. Among catheter-dependent patients with glands >80 cc, over 80% are catheter free after Rezūm. Our experience supports the consideration of Rezūm in patients with prostate glands >80 cc; further studies are warranted to confirm long-term outcomes.

Abstract
OBJECTIVES To evaluate the timing and distribution of first renal cell carcinoma metastasis after nephrectomy stratified by nodal status. METHODS We evaluated patients treated with nephrectomy for sporadic, unilateral renal cell carcinoma between 1970 and 2011 who subsequently developed distant metastasis to three or fewer sites. Site-specific metastases-free 2-year survival rates were estimated using the Kaplan-Meier method. Associations of nodal status with time to metastasis were evaluated using multivariable Cox regression models. RESULTS A total of 1049 patients met the inclusion criteria (135 pN1, 914 pN0/x patients). The median time to identification of first distant metastasis for pN1 patients was 0.4 years (interquartile range 0.2-1.1 years) versus 2.2 years (interquartile range 0.6-6.0 years) in pN0/x patients. The most common site of metastasis was to the lung, but this occurred earlier in pN1 patients (median 0.3 years vs 2.0 years). pN1 was associated with significantly lower site-specific 2-year metastases-free survival when compared with pN0/x for lung (37% vs 70%, P < 0.001), bone (63% vs 87%, P < 0.001), non-regional lymph nodes (60% vs 96%, P < 0.001) and liver metastases (79% vs 91%, P < 0.001). On multivariable analysis, pN1 status remained significantly associated with lung, bone, and non-regional lymph node (all P < 0.001) metastases, but it was no longer associated with liver metastases (P = 0.3). CONCLUSIONS pN1 nodal status in M0 patients treated with nephrectomy for renal cell carcinoma is associated with more frequent early metastasis to sites conferring poor prognosis when compared with pN0/x. Our findings highlight the importance of rigorous, early surveillance though the multimodal use of a comprehensive history, physical, laboratory and radiological studies, as outlined in societal guidelines.

Abstract
BACKGROUND Adjuvant maneuvers are often necessary to correct residual curvature during inflatable penile prosthesis (IPP) placement in patients with Peyronie's disease (PD). AIM We present our multicenter experience using collagen fleece as graft material for plaque incision and grafting (PIG) during IPP placement in patients with moderate to severe PD. METHODS We retrospectively reviewed 51 patients with IPP from 3 sites who underwent PIG with Tachosil (Baxter, IL) collagen fleece. Coloplast (Minneapolis, MN) IPP devices were used. Factors associated with residual curvature, revision, and patient satisfaction were performed using chi-squared analysis. OUTCOMES We evaluated postoperative outcomes including factors associated with residual curvature, revision, and patient satisfaction. RESULTS The mean compound curvature was 69.6°. The mean follow-up was 10.6 (range 1-38) months. All patients reported erections sufficient for penetrative intercourse at the last follow-up. Residual curvature <15° was noted in 6 of 51 (12%) patients. 3 patients required device revision. 2 patients experienced temporary glanular paresthesia, and no patients experienced device infection. CLINICAL IMPLICATIONS In our multicenter study, patients experienced substantial curve correction with minimal complications, and in the few patients who had persistent mild curvature, severe preoperative curvature (>60°) was found to be the only risk factor. STRENGTHS & LIMITATIONS Our study represents the largest series of patients coming from multiple centers undergoing surgical correction of PD with IPP and collagen fleece grafting. Limitations of this study include the retrospective study design, lack of a comparison group, and modest follow-up. CONCLUSION PIG using collagen fleece is a safe and effective means of correcting residual curvature after IPP placement in patients with moderate to severe PD.

Abstract
Abstract
Background
Severe and fulminant Clostridioides Difficile infection(CDI) is associated with increased mortality and morbidity. Current guidelines recommend high dose vancomycin with metronidazole for treatment. Surgery is a high risk for patients failing medical therapy partly due to multiple comorbidities. Emerging evidence suggests efficacy of sequential fecal microbiota transplantation(FMT) by colonoscopy combined with vancomycin in patients failing maximal medical therapy. Fidaxomicin is non-inferior to vancomycin in treating CDI; however, it has not been studied in severe/fulminant cases. It is not known if FMT by enema combined with fidaxomicin is efficacious and safe in this patient population.
Aims
This single center, prospective, open-label pilot study aimed to determine the efficacy and safety of combined sequential FMT by enema plus fidaxomicin in severe or fulminant CDI not responding to maximal medical therapy. Primary outcome was resolution of diarrhea 2 weeks following final FMT. Secondary outcomes were resolution of diarrhea 8 weeks following final FMT, safety of proposed treatment protocol and colectomy rate.
Methods
Consecutive patients with severe or fulminant CDI, who fulfilled study inclusion criteria were recruited. Sequential cycles of FMT, administered by enema daily over three days(720cc followed by 360cc and 180cc), plus fidaxomicin 200mg PO BID were given. Clinical symptoms and inflammatory markers were monitored during the study and subsequent cycles of FMT were administered when clinical or biochemical improvement plateaued. A final FMT was administered with CDI resolution.
Results
A total of three patients were enrolled between Jan 22 to Aug 8, 2019, shown in Table 1. One patient had fulminant CDI due to shock, and the others had severe CDI. All had severe pseudomembranous colitis seen on endoscopy at enrollment. Two of three patients reached both primary and secondary outcomes with 2 FMT cycles. The only patient who did not reach the primary was successfully managed with long term vancomycin suppression. This patient had failed multiple FMTs prior to enrollment. There were no adverse events noted and no colectomy was required during this study.
Conclusions
This pilot study is the first to demonstrate efficacy and safety of combined sequential FMT by enema and fidaxomicin in treating severe or fulminant CDI patients. An adequately powered study is required to validate these findings.

Abstract
Background Up to one in ten patients undergoing cystectomy with urinary diversion develop a ureteroenteric stricture (UES). Despite unrecognized ureteral obstruction contributing to infection, nephrolithiasis, and/or progression of kidney disease, the long-term natural history and risk factors associated with UES remains understudied. Herein, we report our single institutional experience with the long-term incidence, clinical presentation, and risk factors associated with UES formation following urinary diversion. Methods We reviewed 2,285 patients who underwent RC with urinary diversion between 1980-2008. UES was defined as radiographic evidence of ureteral obstruction at the level of the ureteroenteric anastomosis. The diagnosis of benign UES was confirmed by pathology. UES-free survival was estimated using the Kaplan-Meier method. The association between clinicopathologic features and the development of a UES were assessed using multivariable models. Results A total of 192 (8%) patients developed a benign UES, at a median of 7 months (IQR 4-24) following RC, with 5% occurring after 10 years. Seventy seven percent of patients exhibited signs and/or symptoms of ureteral obstruction. Patients who developed a UES had a greater body mass index (BMI) (28 vs. 27), operative time (330 vs. 301 minutes) and were more likely to experience a <30-day Clavien ≥3 complication (all P<0.05). Receipt of abdominal radiation and smoking history were not significantly associated with UES stricture risk. On multivariable analysis, only greater BMI (per 1-unit increase) (OR 1.06, 95% CI: 1.02-1.09; P=0.0009) and <30-day Clavien ≥3 complication (OR 2.85, 95% CI: 1.90-4.28; P<0.0001) were associated with the development of a UES. Development of UES was associated with renal function deterioration. Conclusions UES was identified in 8% of patients following RC with urinary diversion, with the majority presenting with symptoms. While the majority of these occur in the first 2 years after surgery, a patients' risk for the development of this complication persists beyond 10 years. Due to the adverse sequelae of UES, long-term functional and imaging surveillance following urinary diversion is warranted, and early reconstruction should be considered.

Abstract
OBJECTIVE To characterize the frequency and risk factors of peritoneal carcinomatosis (PC) in patients undergoing open radical cystectomy (RC). METHODS We identified 3,285 patients with urothelial carcinoma treated with RC for curative intent between 1980 and 2016. At last follow-up, 72.1% (2,370/3,285) of patients had died, with a median follow-up of 8.6 years (Interquartile Range, (IQR) 3.7, 14.1). PC was defined as any recurrence involving the omentum, small bowel, and mesentery. Overall-specific survival (OSS) and cancer-specific survival (CSS) was evaluated using Kaplan-Meier methodology and log-rank test. Risk factors for mortality and recurrence were performed using Cox proportional hazards regression models. RESULTS One hundred and twenty nine (3.9%) patients were diagnosed with PC, while a total of 1,148 (34.9%) patients experienced recurrence at other sites. Median time to PC vs. other-site recurrence was 1.3 (IQR 1.3, 2.3) and 0.9 (IQR 0.5, 2.1) years, respectively (P= 0.04). Only increasing pathologic stage on multivariable analysis was associated with developing PC (pT1 HR 2.51, 95CI 1.14-5.55, P= 0.02; pT2 OR 2.82, 95CI 1.47-5.43, P= 0.002; pT3+ 2.40, 95CI 1.31-4.42, P= 0.005) over other recurrence patterns. Nodal status and tumor margin status were not associated. Patients with PC experienced worse OSS and CSS than other types of recurrence (P< 0.001). CONCLUSION PC was identified in almost 4% of patients undergoing open RC. PC is a rare occurrence after RC and primarily impacts patients with locally advanced disease.

Abstract
Objective: To compare and analyze the effects of different activators on the release curve of TGF-β(1) and PDGF-AB in platelet rich plasma(PRP). Methods: A total of 36 ml peripheral venous blood was obtained from 10 healthy adult volunteers, and the PRP was made by secondary centrifugation. The platelet activator was made by bovine thrombin 1 000 U in 1 ml 10% calcium chloride solution. The Thrombin-PRP group was made by PRP and the activator in a ratio of 10∶1.The Calcium chloride-PRP group was made in a ratio of 10∶1 by PRP and 10% calcium chloride solution instead. The fresh whole blood(whole blood group) and inactived PRP(PRP group) were used as the control groups. The 4 groups were incubated in warm water of 37 ℃ for 0, 1, 8, 24,72 and 168 h. A quantitative sandwich enzyme-linked immunosorbent assays(ELISA) was used to examine the amount of TGF-β(1) and PDGF-AB in different time points of each group. The release curves of TGF-β(1) and PDGF-AB were based on afore-mentioned data, and then comparisons of the release curves of TGF-β(1) and PDGF-AB in different groups were performed by repeated measurement variance analysis. Results: (1)The levels of TGF-β(1) and PDGF-AB in the whole blood group and the PRP group continued to increase within 168 h. PRP immediately formed into a gel after mixture with thrombin combined and calcium chloride, and the concentrations of TGF-β(1) and PDGF-AB reached the peak in 1 h after activation; increased from (42±21)ng/ml and (77±18)ng/ml to (84±21)ng/ml and (124±35)ng/ml, respectively, and then decreased gradually. The release curve was direct and rapid. The PRP became a gel state in approximate 1 h after mixture with calcium chloride, and the concentrations of TGF-β(1) and PDGF-AB were slowly rising and remained high at 168 h. (2)The AUC(0-168h) of TGF-β(1) and PDGF-AB in the PRP group was higher than that in the whole blood group (all P<0.05) , and the AUC(0-168h) of TGF-β(1) in the Calcium chloride-PRP group was higher than that in the Thrombin-PRP group(Z=-2.26, P<0.05).However, there was no significant difference in the AUC(0-168h) of PDGF-AB between the Calcium chloride-PRP group and the Thrombin-PRP group(Z=-1.512, P=0.131). Conclusion: Using calcium chloride as activator can get a higher release concentration of TGF-β(1) and PDGF-AB and a longer release time, with the largest area under the curve.

Abstract
Background Limited data are available on how partners of men with Peyronie's disease (PD) are affected by the disease. We sought to characterize PD patients whose curvatures result in pain for their partners during penetrative intercourse. Methods We queried a database of all men undergoing initial evaluation for PD at a single clinic between March 2014 and June 2016. Patients were administered a questionnaire regarding sexual health concerns with domains including erectile dysfunction, ejaculatory dysfunction, libido, and penile curvature. In the penile curvature section, patients were specifically asked: "Does the curvature cause your partner any pain during penetrative intercourse? (Y/N)." Patients' partners were not directly evaluated for conditions associated with dyspareunia. Additionally, patients interested in treatment for PD underwent objective curve assessment after intracavernosal injection of erectogenic medications along with penile duplex Doppler ultrasound. Statistical analysis was performed to identify differences in clinicopathologic variables and patient-responses to questionnaire prompts between patients who did and did not report partner pain with intercourse. Results A total of 322 patients with information available on partner pain were included in the study. Patients who reported partner pain had significantly higher subjective erectile rigidity (mean 5.9/10 vs. 4.8/10, P=0.02) and patient-reported penile curvature (47.7° vs. 33.3°, P<0.001) compared to those who did not report pain. Ventral curvatures were more common in men with partner pain (21% vs. 9% of men without, P<0.05). Furthermore, patients complaining of partner pain were more likely to report that PD had a negative impact on relationships and were more interested in pursuing surgical corrections. Conclusions Men with superior erectile function, higher degrees of penile curvature and ventral curvatures were more likely to report partner pain during penetrative intercourse. These specific disease characteristics reported in this series may assist clinicians in identifying men who are more motivated to select more invasive therapies.

Abstract
Purpose To evaluate the impact of incontinence etiology on artificial urinary sphincter (AUS) device outcomes. Materials and Methods We identified 925 patients who underwent primary AUS placement from 1983 to 2011. The etiology of incontinence was categorized as radical prostatectomy alone, radical prostatectomy with radiation, benign prostate resection, and those with cryotherapy as a salvage prostate cancer treatment. Hazard regression and competing risk analyses were used to determine the association of the etiology of incontinence with device outcomes. Results The distribution of the 4 etiologies of incontinence included: 598 patients (64.6%) treated with prostatectomy alone, 206 (22.2%) with prostatectomy and pelvic radiation therapy, 104 (11.2%) with benign prostate resection, and 17 (1.8%) with prior cryotherapy. With a median follow-up of 4.9 years (interquartile range, 1.2–8.8 years), there was significant difference in the cumulative incidence of device infection/urethral erosion events between the four etiologies (p=0.003). On multivariable analysis, prior cryotherapy (reference prostatectomy alone; hazard ratio [HR], 3.44; p=0.01), older age (HR, 1.07; p=0.0009) and history of a transient ischemic attack (HR, 2.57; p=0.04) were associated with an increased risk of device infection or erosion. Notably, pelvic radiation therapy with prostatectomy was not associated with an increased risk of device infection or erosion (reference prostatectomy alone, p=0.30). Conclusions Compared to prostatectomy alone, prior treatment with salvage cryotherapy for recurrent prostate cancer was associated with an increased risk of AUS infection/erosion, whereas radiation (in addition to prostatectomy) was not.

Abstract
Introduction We aimed to develop and validate a self-reported QUAlity of Life Assessment in Spina bifida for Teenagers (QUALAS-T). Material and methods We drafted a 46-question pilot instrument using a patient-centered comprehensive item generation/refinement process. A group of 13–17 years olds with spina bifida (SB) was recruited online via social media and in person at SB clinics (2013–2015). Healthy controls were recruited during routine pediatrician visits. Final questions were identified based on clinical relevance, factor analysis and domain psychometrics. Teenagers with SB completed the validated generic Kidscreen-27 instrument. Results Median age of 159 participants was 15.2 years (42.0% male, 77.4% Caucasian), similar to 58 controls (p ≥ 0.06). There were 102 online and 57 clinic participants (82.8% of eligible). Patients, parents and an expert panel established face and content validity of the 2-domain, 10-question QUALAS-T. Internal consistency and test-retest reliability were high for the Family and Independence and Bladder and Bowel domains (Cronbach's alpha: 0.76–0.78, ICC: 0.72–0.75). The Bladder and Bowel domain is the same for QUALAS-T , QUALAS-A for adults and QUALAS-C for children. Correlations between QUALAS-T domains were low (r = 0.34), indicating QUALAS-T can differentiate between distinct HRQOL components. Correlations between QUALAS-T and Kidscreen-27 were also low (r ≤0.41). QUALAS-T scores were lower in teenagers with SB than without (p <0.0001). Conclusions QUALAS-T is a short, valid HRQOL tool for adolescents with SB, applicable in clinical and research settings. Since the Bladder & Bowel domains for all QUALAS versions are the same, Bladder and Bowel HRQOL can be measured on the same scale from age 8 through adulthood.

Abstract
PURPOSE Chronic kidney disease may adversely affect survival following nephrectomy. Proteinuria is increasingly used as a marker of kidney disease. However, the relationship between preoperative proteinuria and survival after nephrectomy remains incompletely characterized. We evaluated the association of preoperative proteinuria with overall and cancer specific survival using our institutional nephrectomy registry. MATERIALS AND METHODS We identified 1,846 patients with localized clear cell renal cell carcinoma treated with curative intent (radical or partial nephrectomy) between 1995 and 2010. Patients were categorized for analysis based on preoperative proteinuria severity (mild, moderate or severe). Overall and cancer specific survival was estimated by the Kaplan-Meier method. Cox proportional hazards regression models were used to assess for variables associated with overall and cancer specific mortality. RESULTS Preoperative urine protein testing was available in 1,347 patients (73%). A total of 804 patients (60%) were classified with mild proteinuria (less than 150 mg per day), 332 (25%) were classified with moderate proteinuria (150 to 500 mg per day) and 211 (16%) were classified with severe proteinuria (greater than 500 mg per day). On multivariable analysis with mild proteinuria as the reference category the adjusted HR for all cause mortality was 1.18 (95% CI 0.95-1.48, p = 0.14) for moderate proteinuria and 1.61 (95% CI 1.26-2.07, p <0.001) for severe proteinuria. However, the proteinuria level was not associated with cancer specific survival. CONCLUSIONS Severe preoperative proteinuria is associated with worse overall survival following radical or partial nephrectomy for localized clear cell renal cell carcinoma. Preoperative proteinuria should be evaluated in patients undergoing nephrectomy and considered when estimating overall patient health status.

Abstract
INTRODUCTION We evaluated the safety and efficacy of extended duration of pharmacological prophylaxis for preventing symptomatic venous thromboembolism following radical cystectomy. METHODS We recorded symptomatic venous thromboembolism and lymphocele events within 30 days of radical cystectomy among patients treated with extended duration of pharmacological prophylaxis (enoxaparin 40 mg subcutaneously daily for 30 days). We compared these outcomes to those in the cohort of patients who underwent radical cystectomy at our institution in the year prior to extended prophylaxis implementation. Unadjusted descriptive statistics and univariate analyses were performed using the Pearson test or the Fisher chi-square test for categorical variables and the Wilcoxon rank sum test for continuous variables. RESULTS We analyzed the records of 52 patients who did and 82 who did not receive extended duration of pharmacological prophylaxis after radical cystectomy. Only 1 patient (1.9%) discharged home on extended prophylaxis was diagnosed with venous thromboembolism within 30 days of RC compared to 5 (6.1%) who had not received extended prophylaxis. In 3 patients symptomatic lymphocele developed within 30 days of radical cystectomy, including 1 (1.9%) who had received extended prophylaxis and 2 (2.4%) who had not. No patient in either cohort was rehospitalized for bleeding complications. CONCLUSIONS Our initial experience suggests that extended duration of pharmacological prophylaxis is associated with a lower rate of venous thromboembolism following radical cystectomy and it does not increase the risk of bleeding or symptomatic lymphocele. These data warrant validation in larger patient cohorts, ideally in the prospective clinical trial setting.

Abstract
PURPOSE To compare our experience with salvage laparoscopic pyeloplasty, using a matched control set of primary laparoscopic pyeloplasty patients. METHODS We retrospectively reviewed patients who underwent laparoscopic pyeloplasty from 1996 to 2014 by a single surgeon. At least 12 months of follow-up was required. Salvage patients were matched 1:3 with primary patients. Matching was based on age ±5 years, body mass index (BMI) ±5, and type of pyeloplasty (dismembered vs. non-dismembered). Primary outcome was failure as defined as re-intervention following laparoscopic pyeloplasty (does not include temporary stenting without definitive retreatment). RESULTS Of 128 laparoscopic pyeloplasty procedures, ten were salvage. These patients were matched to 26 patients who underwent a primary laparoscopic pyeloplasty in a 1:3 manner. One salvage pyeloplasty failed to match due to BMI, and the closest matches were made. Four salvage patients had one overlapping match, reducing the primary group to 26 patients. There were no differences in pre-, intra-, and postoperative variables between groups, except for operative time (salvage 247 min, primary 175 min, p = 0.03). With similar duration of radiologic and symptomatic follow-up, there was no significant difference in the rate of freedom from intervention. CONCLUSION When matching for factors that could affect success, salvage laparoscopic pyeloplasty performed as well as primary pyeloplasty except for a longer operative time. In experienced hands, salvage laparoscopic pyeloplasty for ureteropelvic junction obstruction recurrence after prior pyeloplasty is a safe and effective procedure, and should be considered an excellent alternative to the more commonly recommended endopyelotomy.

Abstract
OBJECTIVE To assess the effects of locally injected betamethasone on cicatricial tissue hyperplasia in patients with benign central airway stenosis. METHODS A prospective study was conducted with 2 treatment modalities: conventional interventional(CI)therapy, and CI combined with local betamethasone injection(LBI). The average optical density value of TGF-β1 and collagen density in the local airway tissues were compared before therapy and 7 d after the CI treatment and the LBI treatment, respectively. RESULTS Six patients were recruited in this study from May 2013 to June 2015.The results showed significant statistical differences by paired t-test in TGF-β1: 92±38 vs 164±47(t=-7.984, P=0.000)before and after the CI treatment, respectively; 128±45 vs 78±40 (t=10.055, P=0.000)before and after the LBI treatment, respectively. The collagen density was 91 932±59 520 vs 150 252±76 673(t=-8.105, P=0.000) before and after the CI treatment, respectively; 107 024±54 880 vs 114 038±50 772(t=-0.621, P=0.54) before and after the LBI treatment, respectively.Trend comparisons made before and after the treatments showed significant statistical differences in TGF-β1(F=712.139, P=0.000) and in the collagen density (F=261.256, P=0.000)between the CI treatment and the LBI treatment groups. CONCLUSIONS The CI treatment was shown to stimulate the production of TGF-β1 and the deposition of collagen, while the LBI treatment was shown to reduce the production of TGF-β1 and alleviate the deposition of collagen from the stimulation of the CI treatment.

Abstract
INTRODUCTION Interest on the impact of variant histology in bladder cancer prognosis is increasing. Although squamous differentiation is the most well characterized, only recently have less common variants gained increased recognition. We assessed whether squamous differentiation conferred a worse prognosis than nonvariant urothelial bladder cancer in a contemporary cohort of patients treated with radical cystectomy given the increased awareness of other less common variants. METHODS We identified patients with squamous differentiation or nonvariant histology on transurethral resection of bladder tumor and/or cystectomy pathology during a 10-year period. Disease specific and overall survival were evaluated using Kaplan-Meier methodology. Cox regression was used to assess variables associated with mortality. RESULTS Between 2003 and 2013, 934 patients underwent cystectomy for urothelial bladder cancer. Overall 617 nonvariant and 118 squamous differentiation cases were identified, and the remainder was nonsquamous differentiation variant histology. Overall 75% of patients with squamous differentiation had muscle invasive disease at diagnosis compared with 59% of those with nonvariant histology (p=0.002). Nonorgan confined disease at cystectomy was more common in patients with squamous differentiation (57% vs 44%, p=0.009). Among cases on neoadjuvant chemotherapy 20% (9 of 45) of nonvariant and 13% (1 of 8) of squamous differentiation were pT0N0 (p=0.527). Median followup was 52 months. Adjusted for demographics, pathological stage and chemotherapy, squamous differentiation was not associated with an increased risk of disease specific (HR 1.35, 95% CI 0.90-2.04, p=0.150) or all cause mortality (HR 0.90, 95% CI 0.60-1.25, p=0.515). CONCLUSIONS In a contemporary cohort of urothelial bladder cancer with recognition and characterization of less commonly described variants, squamous differentiation is not associated with a worse disease specific and all cause mortality when compared to a pure nonvariant cohort.

Abstract
We investigated the mechanisms of action of immuno-modulatory drug (lenalidomide) on the protein expression of cereblon (CRBN) and their therapeutic targets in the multiple myeloma cell line RPMI8226. The multiple myeloma cell line RPMI8226 was cultured and treated with different concentrations of lenalidomide and bortezomib to determine the proliferation inhibition rate, apoptosis rate, and protein expression of CRBN. The results revealed that both lenalidomide and bortezomib inhibited the proliferation of RPMI8226 and promoted cell apoptosis. However, the protein expression of CRBN decreased signifi-cantly after treatment with lenalidomide, while bortezomib had no effect on the expression of CRBN. We confirmed that CRBN may be a target of lenalidomide.

Abstract
To investigate the change of erection duration measured by stopwatch with flexible dose vardenafil administered for 8 weeks in subjects with erectile dysfunction (ED). Effect of levitra on sustenance of erection was an open-label, prospective, multicenter and single-arm study designed to measure the duration of erection in men with ED receiving a flexible dose of vardenafil over an 8-week treatment period. Patients were instructed to take vardenafil 10 mg 60 min before attempting the intercourse. Vardenfil could be increased to 20 mg or decreased to 5 mg concerning patients' efficacy and safety. Following the initial screening, patients entered a 4-week treatment-free run-in phase and 8-week treatment period, during which they were instructed to attempt intercourse at least four times on four separate days. A total of 95 men were enrolled in 10 centers. After the 8 weeks treatment, the mean duration of erection leading to successful intercourse was statistically superior when patients were treated with vardenafil. After an 8-week treatment, the duration of erection leading to successful intercourse was 9.39 min. There were significant benefits with vardenafil in all domains of International Index of Erectile Function. Secondary efficacy end points included success rate of penetration, maintaining erection, ejaculation and satisfaction were superior when patients were treated with vardenafil. There was a significant correlation between duration of erection with other sexual factors. Also partner's sexual satisfaction was increased with vardenafil. Most adverse events were mild or moderate in severity. Vardenafil was safe and well tolerated. Vardenafil therapy provided a statistically superior duration of erection leading to successful intercourse in men with ED with female partner.

Abstract
PURPOSE While robotic assisted radical nephrectomy is safe with outcomes and complication rates comparable to those of the pure laparoscopic approach, there is little evidence of an economic or clinical benefit. MATERIALS AND METHODS From the 2009 to 2011 Nationwide Inpatient Sample database we identified patients 18 years old or older who underwent radical nephrectomy for primary renal malignancy. Robotic assisted and laparoscopic techniques were noted. Patients treated with the open technique and those with evidence of metastatic disease were excluded from analysis. Descriptive statistics were performed using the chi-square and Mann-Whitney tests, and the Student t-test. Multiple linear regression was done to examine factors associated with increased hospital costs and charges. RESULTS We identified 24,312 radical nephrectomy cases for study inclusion, of which 7,787 (32%) were performed robotically. There was no demographic difference between robotic assisted and pure laparoscopic radical nephrectomy cases. Median total charges were $47,036 vs $38,068 for robotic assisted vs laparoscopic surgery (p <0.001). Median total hospital costs for robotic assisted surgery were $15,149 compared to $11,735 for laparoscopic surgery (p <0.001). There was no difference in perioperative complications or the incidence of death. Compared to the laparoscopic approach robotic assistance conferred an estimated $4,565 and $11,267 increase in hospital costs and charges, respectively, when adjusted for adapted Charlson comorbidity index score, perioperative complications and length of stay (p <0.001). CONCLUSIONS Robotic assisted radical nephrectomy results in increased medical expense without improving patient morbidity. Assuming surgeon proficiency with pure laparoscopy, robotic technology should be reserved primarily for complex surgeries requiring reconstruction. Traditional laparoscopic techniques should continue to be used for routine radical nephrectomy.

Abstract
The three members of the T1R class of taste-specific G protein-coupled receptors have been proven to function in combination with heterodimeric sweet and umami taste receptors in many mammals that affect food intake. This may in turn affect growth traits of livestock. We performed a comprehensive evaluation of single-nucleotide polymorphisms (SNPs) in the bovine TAS1R gene family, which encodes receptors for umami and sweet tastes. Complete DNA sequences of TAS1R1-, TAS1R2-, and TAS1R3-coding regions, obtained from 436 unrelated female cattle, representing three breeds (Qinchuan, Jiaxian Red, Luxi), revealed substantial coding and noncoding diversity. A total of nine SNPs in the TAS1R1 gene were identified, among which seven SNPs were in the coding region, and two SNPs were in the introns. All five SNPs in the TAS1R2 gene and all three SNPs in the TAS1R3 gene were identified in the coding region. Four SNPs (TAS1R1 g.5081C>T, TAS1R1 g.5110C>A, TAS1R2 g.288A>G, TAS1R2 g.2552T>C) were significantly associated with body height of Qinchuan cattle (P<0.05). The heterozygous genotypes of the four SNPs showed a molecular heterosis on cattle heights at hip cross and sacra. The individuals with different genotypic combinations of the four SNPs had significant association with heights at hip cross and sacra (P<0.05).

Abstract
An investigation of the reductive effect of blood pressure and increment of urinary sodium excretion with calcium and potassium supplementation in children with sodium sensitivity is conducted. In total of 261 school children who had completed a 2-year double-blinded, placebo-controlled trial with calcium and potassium supplementation salt sensitivity, with a salt volume expansion and contraction protocol, was determined. The results showed that in children with salt sensitivity, the increase in blood pressure in the supplementary group was lower by 4.3/4.8 mmHg than that in the placebo group (P<0.05), while no significant change was found between the supplementary group and placebo group in children with nonsalt sensitivity. With calcium and potassium supplementation, the night urinary sodium excretion in children with salt sensitivity was significantly increased (P<0.01), and it is negatively correlated with the increase in blood pressure. It was suggested that a moderate increase of calcium and potassium intake in children with salt sensitivity, through interaction with sodium, can promote urinary sodium excretion and may play contribute to the prevention of hypertension.

Abstract
The yak (Bos grunniens) belongs to the cattle family Bovidae and lives in the mountains of China and adjacent areas. Due to the physiological adaptations of yak to its environment and the lack of data, the ivermectin pharmacokinetic was studied following a single subcutaneous dose at the recommended dose for cattle (0.2 mg kg(-1)). The observed peak plasma concentration (Cmax) was 48.93 ng ml(-1) and the time to reach Cmax (Tmax) was 0.73 day. These results show a faster rate of absorption than in cattle. The values for the absorption half-life (t(1/2a)), the distribution half-life (t(1/2alpha)) and the terminal half-life (t(1/2beta)) were 0.31, 0.74 and 4.82 days, respectively. The calculated area under the concentration-time curve (AUC) was 146.2 ng day ml(-1) and the mean residence time (MRT) was 3.57 days. The availability of ivermectin appears low in yaks in comparison to cattle but equivalent to that reported in horses and is likely to be due to physiological characteristics of this species.

Abstract
BACKGROUND The prevalence of antinuclear antibody (ANA) has been documented in patients with hepatitis C virus (HCV) infection. We attempted to determine the titer and to characterize the patterns and clinical significance of ANA in HCV infection. STUDY Forty-eight consecutive patients with positive anti-HCV antibody and positive HCV RNA were included in this study. Sera from patients were tested for ANA and anti-smooth muscle antibody by indirect immunofluorescence. Serum aminotransferase, alkaline phosphatase, alpha-fetoprotein, and cryoglobulin levels also were determined. RESULTS Eleven (23%) of 48 HCV-infected patients were positive for ANA. Antinuclear antibody revealed speckled pattern in 10 (91%) of the 11 ANA-positive HCV-infected patients. Twenty (54%) of 37 ANA-negative HCV-infected patients had detectable pattern with equivocal titer (titer <1.5). The ANA pattern was speckled in all 20 patients. Hepatitis C virus-infected patients with positive ANA were older than the HCV-infected patients with negative ANA (62.90 +/- 11.05 years vs. 56.46 +/- 14.94 years, respectively; p < 0.1). Serum levels of aspartate aminotransferase (39.36 +/- 14.98 IU/L vs. 30.70 +/- 23.15 IU/L, p < 0.05), alkaline phosphatase (189.00 +/- 75.63 IU/L vs. 122.41 +/- 40.88 IU/L, p < 0.01), and alpha-fetoprotein (47.72 +/- 80.47 pg/dL vs. 7.00 +/- 8.28 pg/dL, p < 0.01) were higher in ANA-positive HCV-infected patients than in ANA-negative HCV-infected patients, respectively. There were no significant differences in gender, alanine aminotransferase, anti-smooth muscle antibody, or cryoglobulin between the two groups. CONCLUSIONS Antinuclear antibody was present in 11 (23%) of 48 patients with HCV infection in our study. Speckled pattern is the major expression pattern of ANA in HCV infection. Antinuclear antibody-positive HCV-infected patients have significantly higher serum aspartate aminotransferase, alkaline phosphatase, and alpha-fetoprotein levels than ANA-negative HCV-infected patients.

Abstract
Snakebite may be complicated with bacteria infections, most of which are Gram-negative bacillus. Snakebite complicated with Vibrio vulnificus infection has not been reported previously. Vibrio vulnificus infection is characterized by a necrotizing wound infection similar to the local lesion of severe snakebite. In Vibrio infections, aggressive debridement with the administration of strong antibiotics as early as possible is the only effective treatment. We report a 79-y-o man who suffered from snakebite on the right palm with rapid progression of hemorrhagic bulla, necrotizing fasciitis, compartment syndrome, and septic shock. Vibrio vulnificuswas cultured from necrotic tissue after aggressive debridement and fasciotomy. The patient recovered from antibiotic treatment and several courses of reconstruction surgery. Severe bacteria infection, such as caused by Vibrio vulnificus, should be considered in snakebite cases refractory to antivenin dosage.
