ABSTRACT

The aim of this work was to synthesize a green nanoparticle SnCuO@FeO nanocomposite core-shell to break oily water emulsions during petroleum-enhancing production processes as an alternative to chemical and physical processes. In this study, eight bacterial isolates (MHB1-MHB8) have been isolated from tree leaves, giant reeds, and soil samples. The investigation involved testing bacterial isolates for their ability to make FeO nanoparticles and choosing the best producers. The selected isolate (MHB5) was identified by amplification and sequencing of the 16S rRNA gene as Bacillus paramycoides strain OQ878685. MHB5 produced the FeO nanoparticles with the smallest particle size (78.7 nm) using DLS. XRD, FTIR, and TEM were used to characterize the biosynthesized nanoparticles. The jar experiment used SnCuO@FeO with different ratios of Sn to CuO (1:1, 2:1, and 3:1) to study the effect of oil concentration, retention time, and temperature. The most effective performance was observed with a 1:1 ratio of Sn to CuO, achieving an 85% separation efficiency at a concentration of 5 mg/L, for a duration of 5 min, and at a temperature of 373 K. Analysis using kinetic models indicates that the adsorption process can be accurately described by both the pseudo-first-order and pseudo-second-order models. This suggests that the adsorption mechanism likely involves a combination of film diffusion and intraparticle diffusion. Regarding the adsorption isotherm, the Langmuir model provides a strong fit for the data, while the D-R model indicates that physical interactions primarily govern the adsorption mechanism. Thermodynamic analysis reveals a ∆H value of 18.62 kJ/mol, indicating an exothermic adsorption process. This suggests that the adsorption is a favorable process, as energy is released during the process. Finally, the synthesized green SnCuO@FeO nanocomposite has potential for use in advanced applications in the oil and gas industry to help the industry meet regulatory compliance, lower operation costs, reduce environmental impact, and enhance production efficiency.

ABSTRACT

OBJECTIVE: Data regarding the imbalance in follicular helper T (Tfh) and follicular regulatory T (Tfr) cell responses in patients having chronic rhinosinusitis with nasal polyps (CRSwNP) is so far limited. Thus, we aimed to assess the changes in circulating Tfh and Tfr in CRSwNP patients. METHODS: This case-control study included 21 patients having CRSwNP and 20 age and sex-matched healthy blood donors as a control group. Lund-Mackay staging system was used for radiologic scoring of chronic rhinosinusitis. Two milliliters of peripheral blood samples were collected from all participants into EDTA-containing vacutainer tubes to assess the levels of Tfh and Tfr cells using flow cytometry. RESULTS: Patients having CRSwNP did not show significant differences in the percentages of CD4+ T cells and total CD4+CXCR5+ T cells from healthy controls. Meanwhile, levels of both activated circulating Tfh and Tfr showed a marked rise in patients than controls. In addition, a positive correlation was observed between the levels of both activated Tfh and Tfr cells. CONCLUSION: An imbalance in circulating Tfh/Tfr levels was detected in patients having CRSwNP. A significant rise in the levels of Tfh and Tfr was detected in patients proposing a possible role of this imbalance in disease pathogenesis.

ABSTRACT

OBJECTIVE: To assess the efficacy of primary urethral realignment in the prevention of urethral stenosis and in simplifying delayed urethroplasty after complete pelvic fracture urethral injury in male children. METHODS: This randomized comparative trial included 40 boys <18 years with complete pelvic fracture urethral injury. The initial management was a primary urethral realignment in 20 boys and suprapubic cystostomy alone in the remaining 20 boys. The boys who underwent primary urethral realignment were assessed regarding the development of urethral stenosis. Boys who needed to be delayed urethroplasty in the two groups were compared regarding urethral defect length, intraoperative details, postoperative outcomes, number of procedures, and time to achieve normal voiding. RESULTS: Although 14 (70%) patients were able to void after primary urethral realignment, all of them developed urethral stenosis and needed delayed urethroplasty. No statistically significant difference between the two groups was found regarding urethral defect length, intraoperative details, and postoperative outcomes. Patients in the primary urethral realignment group underwent significantly more procedures (p < 0.001) and took a significantly longer time to achieve normal voiding (p = 0.002). CONCLUSION: Primary urethral realignment is neither able to prevent urethral stenosis nor effective in simplifying later urethroplasty after complete pelvic fracture urethral injury in male children. It exposes the patients to more surgical procedures and a prolonged clinical course.

ABSTRACT

Objective: The objective of this study is to compare the outcome of percutaneous nephrostomy by ultrasound (US) versus fluoroscopy including access time, volume of anesthesia required, success rate, and complications. Methods: One hundred patients were enrolled in a prospective randomized study. Patients were divided into two groups, 50 cases each. Comparing the two groups was done regarding the need for dye, radiation effect, time taken, trial number, rate of complication, volume of anesthesia, and success rate. Results: Patient demographics were comparable between both groups with no statistically significant difference. According to the modified Clavien-Dindo classification, the complications were Grade I (pain and mild hematuria) in each group. Procedural pain was present in 41 (82%) patients in Group I and in 48 (96%) patients in Group II. It was treated in both groups with a simple analgesic. Mild hematuria was present in 5 (10%) patients in the US group and 13 (26%) in the fluoroscopic group and treated by hemostatic drugs only. There was a statistically significant difference between both groups regarding the volume of required local anesthesia, the trial numbers, the puncture numbers, bleeding, extravasation, and change in the hemoglobin level. Conclusion: US percutaneous renal access is a safe and effective modality with a high success rate, less operative time, and complication rate. However, a minimum of 50 cases with some pelvicalyceal system dilation may be preliminary requisites to achieve good orientation and competence in achieving safe US percutaneous renal access for future endourological procedures.

ABSTRACT

PURPOSE: To compare the clinical results and patients' health-related quality of life (HR-QoL) of ileal conduit (IC) versus single stoma uretero-cutanoustomy (SSUC) after radical cystectomy in two groups of randomly selected patients ≥ 75 years. METHODS: From January 2013 to March 2018, 100 patients ≥ 75 years with muscle invasive BCa underwent RCX and cutaneous diversion. Patients were divided in two groups; group I underwent IC (50 patients) and group II underwent SSUC (50 patients). Postoperative evaluation included clinical, laboratory, radiographic and HR-QoL. The latter was performed using the Functional Assessment of Cancer Therapy-Bladder Cancer (FACT-BL) after 12 months postoperatively. RESULTS: Patients' characteristics were comparable between both groups. No intraoperative complications occurred. Early postoperative complications occurred in 27 patients [16 (35.5%) in group I and 11 (23.9%) in group II (p = 0.02)]. Delayed postoperative complications occurred in 26 patients [6 (13.3%) in group I and 20 (43.4%) in group II, (P = 0.002)]. No significant differences between both groups regarding the physical, social/family, emotional, functional and additional concerns scales of FACT-BL questionnaire were reported. CONCLUSION: SSUC is a good alternative to IC in elderly frail patients ≥ 75 years and those with multiple comorbidities who require rapid surgery in terms of perioperative complications and HR-QoL. However, the stomal complications and the possibility of a frequent stent exchange are considered its drawbacks.

ABSTRACT

BACKGROUND: The function of different populations of the immune system in bladder cancer (BCa) is well established. However, the cohesive role of the immune cell profile of schistosomal BCa at systemic and tissue levels is still lacking, especially in endemic countries. The balance hypothesized between protumorigenic and antitumor molecules determines the prognosis of tumor progression. This study aimed to investigate the frequency of T cell subsets at both blood and tumor tissue, regulatory T(Treg), regulatory B cells (Breg) and proinflammatory cytokines in S. haematobium-related BCa patients in Egypt. METHODOLOGY/PRINCIPAL FINDINGS: The frequency of T cell subsets at both blood and tumor tissue, regulatory T(Treg), regulatory B cells (Breg) were studied by flow cytometry and proinflammatory cytokines by ELISA in S. haematobium-related BCa patients in Egypt. The results indicated a significant increase in the activity of T-cell populations, particularly CD3+, CD4+, and regulatory T cells (Tregs), and a decrease in cytotoxic CD8+ T cells in the patient group. An increased proportion of CD19+CD24+CD38+ Bregs and proinflammatory cytokines (IL-1ß, IL-6, and TNF-α) was also observed. However, T-cell subpopulations in the tumor microenvironment showed a significant reduction in cancer patients compared to controls. Moreover, positive correlations were observed between the frequencies of Bregs and Tregs, suggesting the promotion of cancer progression besides their relation to the intensity of schistosomal infection. CONCLUSIONS/SIGNIFICANCE: Trapped Schistosoma haematobium eggs in bladder tissue might lead to persistent inflammation that contributes to immunomodulation and promotes tumor progression, as evidenced by the increase in peripheral T helper, Tregs, Bregs and serum tumor-promoting cytokines. Considering the role and integrated functions of specific immune responses in BCa could help future diagnostic and therapeutic implications.

ABSTRACT

OBJECTIVES: to assess the functional outcome of performing ureteric re-implantation to an angled short chimney in a modified spiral orthotopic ileal neobladder. PATIENTS AND METHODS: From January 2018 to December 2020, 90 male patients with bladder cancer underwent radical cystectomy and spiral ileal neobladder reconstruction with a chimney. Patients were randomly divided in two groups according to the position of the chimney [straight and angled] to which the ureters will be implanted. Postoperative evaluation included clinical, laboratory, radiographic and urodynamic studies. RESULTS: There were no perioperative deaths. The mean operative time for the procedure was 4.7 ± 1.2 h in group I and 4.9 ± 1.3 h in group II (p 0.456). No intraoperative complications occurred. Early postoperative complications occurred in 8 patients. In group I, according to the modified Clavien system, GII complication occurred in 2 (5%) patients in the form of DVT in 1 (2.5%) and surgical site infection in 1 (2.5%). GIIIa occurred in 3 (7.5%) patients in the form of wound dehiscence. In group II, GII occurred in 2 (4.8%) patients in the form of prolonged urinary leakage and myocardial infarction, each occurred in one patient. GIIIb occurred in 1 (2.4%) patient in the form of intestinal leak. Poucho-ureteral reflux occurred in 10 patients [3 (7.5%) in group I and 7 (16.8%) in group II (p 0.001)]. CONCLUSIONS: The preliminary results of the right sided angled chimney during neobladder reconstruction are safe, acceptable, without an extra time to develop an anti-reflux technique and without an increased incidence of reflux.

ABSTRACT

OBJECTIVE: To determine the influence of adding maze control training to the selected conventional physical therapy on kinesthetic awareness in patients with chronic stroke. METHODS: Thirty adult patients of both genders with chronic cerebral stroke were assigned to control and experimental groups randomly: the control group (A) received the selected conventional physical therapy rehabilitation program, while the experimental group (B) received the same program as group A in addition to the maze control training. Measurements for sway index, risk of fall, and knee proprioception before and after 8 weeks of treatment (24 sessions; three times per week). RESULTS: There were significant decreases of both sway index and risk of fall in both groups (p ≤ 0.001 in all measures), significant improvements of the knee proprioception in 30° and 75° in the experimental group (p value = 0.016 and ≤0.001, respectively). The in-between groups' comparison showed significant differences corresponding to both the sway index and risk of fall (p ≤ 0.001), and a significant difference in 75° (p ≤ 0.001). CONCLUSION: Adding maze control training to the selected conventional physical therapy improved the kinesthetic awareness in patients with chronic stroke.

ABSTRACT

BACKGROUND: Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS). Aberrant expression of transcription factor forkhead box P3 (FoxP3) has been suggested to underlie different immunological disorders as FOXP3 expression is essential for T regulatory cells (Tregs) to maintain their suppressive and anti-inflammatory functions and exert immunologic self-tolerance. Interleukin-35 (IL-35) is an important immunosuppressive cytokine that is produced mainly by CD4+ FOXP3+ Tregs. OBJECTIVES: To assess the possible role of the FOXP3 rs3761548 (C/A) single-nucleotide variation (SNV) in relapsing-remitting multiple sclerosis (RRMS). Also, measurement of the serum IL-35 concentration and study its relation to different genotypes and the degree of disease-related disability. METHODS: A total of 100 RRMS patients and 90 healthy control subjects were subjected to genotyping for the FOXP3 (rs3761548) variant by TaqMan real-time PCR, and measurement of the IL-35 level in their sera by Elisa. RESULTS: The frequencies of the AA genotype and A allele were significantly higher in the MS patients than in the healthy controls (P=0.008, OR=2.53, 95% CI=1.27-5.04; P=0.001, OR=1.98, 95% CI=1.31-3.00, respectively). There was a significant association between FOXP3 rs3761548 variant and female MS patients. The serum IL-35 level was significantly higher in MS patients (1372 [575-2192] pg/mL) compared to healthy controls (604 [454-696] pg/mL) (P<0.0001). No significant differences were found between the different FOXP3 genotypes and EDSS score (P=0.730). CONCLUSION: The FOXP3rs3761548 gene variant may influence the genetic susceptibility to MS rather than affecting its course, severity or progression. The serum IL-35 level might have a role in the development of the disease, however its role in disease-related disability is questionable.

ABSTRACT

To evaluate the diagnostic performance and clinical significance of 4 systems of substaging cases with non-muscle invasive urothelial bladder carcinoma. In addition 4 cutoff measures were evaluated for prediction of muscularis-mucosa invasion. Four substaging systems were applied to 57 NMIBC cases to assess which of these reported methods correlates best with recurrence and progression. On univariate regression analysis patients having tumor size more than 3 cm, solid tumor architecture, high grade, substage B, substage T1e, substage ROL 2 and Tumor depth more than 1 mm were associated with higher recurrence. On multivariate analysis all the four substaging systems, tumor size, grade and tumor type had significant prognostic value for recurrence. Regarding progression only the metric substaging method was associated with tumor progression (p = 0.04). However, on univariate and multivariate regression analysis none of the substaging systems showed prognostic significance and only solid tumor architecture and CIS had significant prognostic value for tumor progression. The ROC curve analysis showed that 1 mm depth of invasion had the best accuracy for detection of muscularis-mucosa invasion (80.2%). Using 1 mm cutoff in measuring the depth and 0.5 mm for the diameter of infiltration may provide clinically relevant information to guide a more personalized therapy for NMIBC. Inclusion of both measures in addition to other histopathologic variables may aid in the development of a scoring system.

ABSTRACT

Clostridia-especially Clostridium butyricum-are among the taxa most frequently identified from stool samples of preterm neonates with necrotizing enterocolitis (NEC). Recently, Clostridium neonatale has also been detected from epidemic cases, but using a culture-based approach we were unable to confirm this discovery in a local cohort. In order to investigate this link by a molecular approach, a specific rpoB-based quantitative real-time PCR was developed to detect C. neonatale directly from patients' stool specimens. Design of this rpoB-based quantitative real-time PCR was based on the genomic analysis of seven clinical isolates of C. neonatale. It was tested on stool samples from 88 preterm neonates with necrotizing enterocolitis and 71 matched controls. C. neonatale was significantly more prevalent in stools from preterm neonates with necrotizing enterocolitis than in controls (respectively 30/88 (34%) versus 9/71 (13%); p 0.003). Whole-genome analysis also allowed the identification of three genomic clusters of C. neonatale. This clustering was associated with a geographical location regardless of isolation from the NEC or control, suggesting asymptomatic carriage. Although less prevalent than C. butyricum in our cohort, C. neonatale is significantly associated with the occurrence of necrotizing enterocolitis.

ABSTRACT

Using the strategy of taxonogenomics, we described Clostridium pacaense sp. nov. strain Marseille-P3100T, a Gram-variable, nonmotile, spore-forming anaerobic bacillus. This strain was isolated from a 3.3-month-old Senegalese girl with clinical aspects of marasmus. The closest species based on 16S ribosomal RNA was Clostridium aldenense, with a similarity of 98.4%. The genome length was 2 672 129 bp, with a 50% GC content; 2360 proteins were predicted. Finally, predominant fatty acids were hexadecanoic acid, tetradecanoic acid and 9-hexadecenoic acid.

ABSTRACT

Febrile seizures (FS) are frequent convulsive disorders, occurring in infants and young children. The present study aims to assess and compare the serum levels of oxidative stress markers and some essential trace minerals in FS with normal or abnormal EEG and evaluate the effect of antioxidant therapy on the clinical outcome. This study has been carried out on 80 children with FS (40 with simple FS and 40 with complex FS) and 40 febrile children without seizures. Clinical and EEG findings were recorded for the included patients. Biochemical assays of serum nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD), copper (Cu), zinc (Zn) and selenium (Se), using colorimetric methods, were measured in the studied groups. The overall results showed an increased values of NO, MDA and Cu with decreased values of SOD, Zn and Se in patients with FS (simple and complex) in comparison with febrile children without seizures (p < 0.05 for all). Additionally, NO and MDA was increased in complex FS patients with EEG abnormalities in comparison with complex FS with normal EEG findings (p < 0.05); NO and MDA were also significantly decreased after valproate therapy in complex FS patients (p < 0.05 for all). In conclusions, oxidative stress, decreased Zn and Se with increased Cu may play a role in FS. Valproate improves the oxidative stress status in complex FS.

ABSTRACT

BACKGROUND: To compare the results of urethral anastomosis to a button hole and to the lowest part of the anterior suture line during orthotopic neobladder substitution. METHODS: From January 2012 to December 2015, 87 consecutive male patients with invasive bladder cancer underwent radical cystectomy and Hautmann ileal neobladder. Patients were randomly divided into two groups; group I (44 patients), the outlet was created as a button-hole at the most dependent part of the pouch, group II (43 patients), the lowest 1 cm of the anterior suture line of the pouch was left open as an outlet. Patients were randomly assigned to either group using computer-generated random numbers (JMP, Version 12.0.1; SAS Institute, Cary, NC, USA) via a sealed envelope. The functional outcomes of both groups were compared especially at the urethro-enteric anastomosis. RESULTS: There were no intraoperative complications. Early postoperative complications occurred in 9 patients (5 in group I and 4 in group II, p = 0.484). Prolonged urinary leakage persisted for 11 and 14 days in 2 patients in group I and 10 and 16 days in 2 patients in group II. Delayed postoperative complications occurred in 11 patients (5 [12.5%] in group I and 6 [15.6%] in group II) (p = 0.711). Three patients developed urethro-enteric strictures (2 in group I and 1 in group II) (p = 0.571). CONCLUSION: The "non-hole" technique of urethral anastomosis was not associated with a significant increase in the complication rate when compared to the commonly performed "hole" technique.

ABSTRACT

INTRODUCTION: Obstructive anuria can be managed by primary ureteroscopy (URS) or deferred URS after initial ureteral stenting. We want to compare the primary URS and deferred URS in the management of calculus anuria regarding the feasibility and clinical outcome. MATERIAL AND METHODS: Between January 2012 and December 2014, 150 patients with anuria due to ureteral calculi were prospectively randomized according to the timing of ureteroscopic intervention into two groups; deferred URS group (69 patients who were treated initially by ureteral stenting) and primary URS group (81 patients who were treated by emergency URS). Follow-up was at least 6 months postoperatively. RESULTS: Complete stone clearance was 87 % and 75.3% for deferred and primary URS groups, respectively (p = 0.097). Renal function normalized in 94.2% of deferred URS vs. 97.5% of primary URS (p = 0.414). Deferred URS group had a 2.9 % overall complication rate in comparison to 9.9 % for the primary URS group (p = 0.109). Ureteral perforation/pyelonephritis was noted in 6.2% of the primary URS group only (p = 0.043). The median number of maneuvers required until stone clearance was one (range 1-5) for primary URS vs. two (range 2-3) for deferred URS (p <0.001). The cost of primary URS was significantly less (p <0.001). On a multivariate analysis, lower ureteral calculi (OR 13.03, 95% CI 4.07- 41.7, p <0.001) and deferred URS (OR 2.84, 95% CI 1.07-7.49, p = 0.035) were independent predictors for an eventless and successful URS. CONCLUSIONS: Primary URS for calculus anuria is feasible and cost-effective. It has a short hospital stay, but is still technically demanding. The perioperative complications are comparable to URS in normouric patients.

ABSTRACT

OBJECTIVE: The aim of this study was to report the functional outcome after endoscopic management of neobladder complications. MATERIALS AND METHODS: Out of 197 patients who underwent radical cystectomy and orthotopic ileal neobladder reconstruction between 2007 and 2013, 30 patients with delayed postoperative complications were enrolled in this study. Complications were in the form of: eight patients with outflow obstruction, 12 with ureteroenteric stricture, nine with neobladder calculi and one with an isolated recurrent papillary tumor inside the neobladder. Patients were followed up regularly to assess the outcomes of endoscopic treatment. RESULTS: The mean maximum flow rate and postvoiding residual urine after endoscopic treatment of outflow obstruction were 18.2 ± 3.9 ml/s and 28.7 ± 11 ml, respectively. Ten patients with ureteroenteric stricture showed resolution of hydronephrosis after antegrade dilatation and JJ-stent fixation, with two patients requiring open surgery owing to impassable strictures. Complete clearance of neobladder calculi occurred after endoscopic neocystolithotripsy, with two patients requiring two sessions owing to large calculi. Transurethral resection of the neobladder for isolated tumor recurrence was performed in one patient over two sessions, followed by adjuvant chemoirradiation. CONCLUSIONS: Endourological management of orthotopic neobladder problems is the safest choice. It avoids the difficulties and complications of open surgery and has durable results.

ABSTRACT

BACKGROUND: Levobupivacaine is an effective local anesthetic agent with less systemic toxicity than racemic bupivacaine, but it has short postoperative analgesic duration. Dexmedetomidine and fentanyl are promising adjuncts to provide excellent and prolonged postoperative caudal analgesia. This study compared the effects of caudal levobupivacaine plus dexmedetomidine and levobupivacaine plus fentanyl for postoperative analgesia and sedation in children undergoing lower limb orthopedic surgery. PATIENTS AND METHODS: Ninety children, whose age ranged from 1 to 7 years, American Society of Anesthesiologists I-II, undergoing orthopedic lower limb surgery under general anesthesia received caudal block for postoperative analgesia. The children were randomly allocated into three groups: Group L (control) received 0.75 ml/kg levobupivacaine 0.25% diluted in saline; Group LD received 0.75 ml/kg levobupivacaine 0.25% with dexmedetomidine 1 µg/kg; and Group LF received 0.75 ml/kg levobupivacaine 0.25% with fentanyl 1 µg/kg. Following the administration of the drugs; hemodynamic variables, the total anesthesia time, sedation score, Face, Legs, Activity, Cry, Consolability score, duration of analgesia, and side effects were recorded. RESULTS: Demographically, all the groups were comparable, both the baseline and the intraoperative hemodynamic profile were similar in all groups. The mean duration of analgesia and the mean sedation score in the Group LD were significantly greater as compared to both the other groups. CONCLUSION: Dexmedetomidine may be a better additive to levobupivacaine than fentanyl for caudal postoperative analgesia, arousable sedation with comparable hemodynamic and side effect profile in children.

Clostridium phoceensis sp. nov., strain GD3T (= CSUR P1929 = DSM 100334) is the type strain of C. phoceensis sp. nov., a new species within the genus Clostridium. This strain was isolated from the gut microbiota of a 28-year-old healthy French man. C. phoceensis is a Gram-negative, spore-forming, nonmotile, strictly anaerobic bacterium. We describe its complete genome sequence and annotation, together with its phenotypic characteristics.

ABSTRACT

The treatment failure often happens in overactive bladder (OAB) partly owing to its unknown pathogenesis. The purpose of this study is to find significant receptors or biological markers for OAB-related symptoms for establishment of potential order-made therapeutic strategies. The overactive bladder symptom scores (OABSS) and international prostate symptom scores (IPSS)/quality of life (QOL) were questioned in all the 18 patients with OAB diagnosis. Their bladder mucosal tissues were taken from the random biopsy of bladder cancer suspected patients without any finding such as inflammation or carcinoma in situ. They were investigated quantitatively by immunohistochemical (IHC) stainings for inflammatory or immune-system (Interleukin (IL)-6 and cyclooxygenase-2 (Cox-2)), Caspase-3 apoptosis markers, angiogenesis (CD-31), epithelial-mesenchymal transition (E-cadherin) and muscarinic receptor (Muscarine-2 (M)-2), adrenergic receptors (ARs) (alpha 1-d (α1-d) and beta-3 (ß-3)). The statistical correlation between the expressions of these 5 markers and 3 receptors and these symptom scores were examined under the comparison between OAB patients and control patients who had urgency score with less than 2 in OABSS. The OABSS and IPSS/QOL was 7.39 ± 2.69 and 21.2 ± 6.59/4.33 ± 1.33, respectively but those of control patients were 2.00 ± 1.41 and 10.1 ± 9.52/2.14 ± 1.46, respectively (P<0.05). Regarding the correlation of those markers' expressions and symptom scores, in OAB patients, OABSS total significantly correlated with ß-3 AR expressions (P=0.0457). IPSS post-voiding significantly correlated with ß-3 AR expressions (P=0.0308) but no significant relationship in control patients (P>0.05). In conclusion, this study demonstrated that ß-3 AR in our tested 8 markers or receptors was correlated strongly with OAB-related symptoms. These data may help elucidate the pathophysiology of OAB and offer possible strategy for its order-made therapies.
