Abstract

To understand the residents' perceptions of the, COVID-19 driven, newly implemented online learning systems adopted among accredited urology residency programs nationwide, and their sustainability following the pandemic era.A survey was designed and dispersed to urology program coordinators and directors to distribute to their residents. In the survey, Online education models was the all-encompassing term to describe any form of resident education that occurred online. Anonymous surveys were exported from Survey Monkey and data was analyzed for statistical significance.Over 70% of urology residents agreed or were neutral to the statement that Online education models were equivalent to in-person learning. Only 13% of residents stated that online learning should not be continued following the pandemic. Several different parameters were assessed, and only 5 of them showed statistical significance. Stress, personal engagement, interpersonal communication efficiency and non-verbal cues were all lower with online education models. The only attribute that was scored higher by residents was network connectivity issues.An overwhelming majority of urology residents in the United States believe Online education models should continue to be adopted once the pandemic is over.

Abstract

Aims: Guidelines recommend down-titration of loop diuretics (LD) once euvolaemia is achieved. In outpatients with heart failure (HF), we investigated LD dose changes in daily cardiology practice, agreement with guideline recommendations, predictors of successful LD down-titration and association between dose changes and outcomes. Methods and results: We included 8130 HF patients from the ESC-EORP Heart Failure Long-Term Registry. Among patients who had dose decreased, successful decrease was defined as the decrease not followed by death, HF hospitalization, New York Heart Association class deterioration, or subsequent increase in LD dose. Mean age was 66 ± 13 years, 71% men, 62% HF with reduced ejection fraction, 19% HF with mid-range ejection fraction, 19% HF with preserved ejection fraction. Median [interquartile range (IQR)] LD dose was 40 (25–80) mg. LD dose was increased in 16%, decreased in 8.3% and unchanged in 76%. Median (IQR) follow-up was 372 (363–419) days. Diuretic dose increase (vs. no change) was associated with HF death [hazard ratio (HR) 1.53, 95% confidence interval (CI) 1.12–2.08; P = 0.008] and nominally with cardiovascular death (HR 1.25, 95% CI 0.96–1.63; P = 0.103). Decrease of diuretic dose (vs. no change) was associated with nominally lower HF (HR 0.59, 95% CI 0.33–1.07; P = 0.083) and cardiovascular mortality (HR 0.62,. 95% CI 0.38–1.00; P = 0.052). Among patients who had LD dose decreased, systolic blood pressure [odds ratio (OR) 1.11 per 10 mmHg increase, 95% CI 1.01–1.22; P = 0.032], and absence of (i) sleep apnoea (OR 0.24, 95% CI 0.09–0.69; P = 0.008), (ii) peripheral congestion (OR 0.48, 95% CI 0.29–0.80; P = 0.005), and (iii) moderate/severe mitral regurgitation (OR 0.57, 95% CI 0.37–0.87; P = 0.008) were independently associated with successful decrease. Conclusion: Diuretic dose was unchanged in 76% and decreased in 8.3% of outpatients with chronic HF. LD dose increase was associated with worse outcomes, while the LD dose decrease group showed a trend for better outcomes compared with the no-change group. Higher systolic blood pressure, and absence of (i) sleep apnoea, (ii) peripheral congestion, and (iii) moderate/severe mitral regurgitation were independently associated with successful dose decrease. © 2020 European Society of Cardiology

Abstract

Aims: This study aimed to assess age- and sex-related differences in management and 1-year risk for all-cause mortality and hospitalization in chronic heart failure (HF) patients. Methods and results: Of 16 354 patients included in the European Society of Cardiology Heart Failure Long-Term Registry, 9428 chronic HF patients were analysed [median age: 66 years; 28.5% women; mean left ventricular ejection fraction (LVEF) 37%]. Rates of use of guideline-directed medical therapy (GDMT) were high (angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers and mineralocorticoid receptor antagonists: 85.7%, 88.7% and 58.8%, respectively). Crude GDMT utilization rates were lower in women than in men (all differences: P ≤ 0.001), and GDMT use became lower with ageing in both sexes, at baseline and at 1-year follow-up. Sex was not an independent predictor of GDMT prescription; however, age >75 years was a significant predictor of GDMT underutilization. Rates of all-cause mortality were lower in women than in men (7.1% vs. 8.7%; P = 0.015), as were rates of all-cause hospitalization (21.9% vs. 27.3%; P 75 years. Conclusions: There was a decline in GDMT use with advanced age in both sexes. Sex was not an independent predictor of GDMT or adverse outcomes. However, age >75 years independently predicted lower GDMT use and higher all-cause mortality in patients with LVEF ≤45%. © 2019 The Authors.

Abstract

Aims: We assessed the interplay between hyperkalaemia (HK) and renin–angiotensin–aldosterone system inhibitor (RAASi) use, dose and discontinuation, and their association with all-cause or cardiovascular death in patients with chronic heart failure (HF). We hypothesized that HK-associated increased death may be related to RAASi withdrawal. Methods and results: The ESC-HFA-EORP Heart Failure Long-Term Registry was used. Among 9222 outpatients (HF with reduced ejection fraction: 60.6%, HF with mid-range ejection fraction: 22.9%, HF with preserved ejection fraction: 16.5%) from 31 countries, 16.6% had HK (≥5.0 mmol/L) at baseline. Angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) was used in 88.3%, a mineralocorticoid receptor antagonist (MRA) in 58.7%, or a combination in 53.2%; of these, at ≥50% of target dose in ACEi: 61.8%; ARB: 64.7%; and MRA: 90.3%. At a median follow-up of 12.2 months, there were 789 deaths (8.6%). Both hypokalaemia and HK were independently. associated with higher mortality, and ACEi/ARB prescription at baseline with lower mortality. MRA prescription was not retained in the model. In multivariable analyses, HK at baseline was independently associated with MRA non-prescription at baseline and subsequent discontinuation. When considering subsequent discontinuation of RAASi (instead of baseline use), HK was no longer found associated with all-cause deaths. Importantly, all RAASi (ACEi, ARB, or MRA) discontinuations were strongly associated with mortality. Conclusions: In HF, hyper- and hypokalaemia were associated with mortality. However, when adjusting for RAASi discontinuation, HK was no longer associated with mortality, suggesting that HK may be a risk marker for RAASi discontinuation rather than a risk factor for worse outcomes. © 2020 European Society of Cardiology

Gunes, H. on behalf of the ESC-EORP-HFA Heart Failure Long-Term Registry Investigators

Abstract

Aims: Classification of acute heart failure (AHF) patients into four clinical profiles defined by evidence of congestion and perfusion is advocated by the 2016 European Society of Cardiology (ESC)guidelines. Based on the ESC-EORP-HFA Heart Failure Long-Term Registry, we compared differences in baseline characteristics, in-hospital management and outcomes among congestion/perfusion profiles using this classification. Methods and results: We included 7865 AHF patients classified at admission as: ‘dry-warm’ (9.9%), ‘wet-warm’ (69.9%), ‘wet-cold’ (19.8%) and ‘dry-cold’ (0.4%). These groups differed significantly in terms of baseline characteristics, in-hospital management and outcomes. In-hospital mortality was 2.0% in ‘dry-warm’, 3.8% in ‘wet-warm’, 9.1% in ‘dry-cold’ and 12.1% in ‘wet-cold’ patients. Based on clinical classification at admission, the adjusted hazard ratios (95% confidence interval) for 1-year mortality were: ‘wet-warm’ vs. ‘dry-warm’ 1.78 (1.43–2.21) and ‘wet-cold’ vs. ‘wet-warm’ 1.33 (1.19–1.48). For profiles resulting from discharge classification, the adjusted hazard ratios (95% confidence interval) for 1-year mortality were: ‘wet-warm’ vs. ‘dry-warm’ 1.46 (1.31–1.63) and ‘wet-cold’ vs. ‘wet-warm’ 2.20 (1.89–2.56). Among patients discharged alive, 30.9% had residual congestion, and these patients had higher 1-year mortality compared to patients discharged without congestion (28.0 vs. 18.5%). Tricuspid regurgitation, diabetes, anaemia and high New York Heart Association class were independently associated with higher risk of congestion at discharge, while beta-blockers at admission, de novo heart failure, or any cardiovascular procedure during hospitalization were associated with lower risk of residual congestion. Conclusion: Classification based on congestion/perfusion status provides clinically relevant information at hospital admission and discharge. A better understanding of the clinical course of the two entities could play an important role towards the implementation of targeted strategies that may improve outcomes. © 2019 The Authors.

11. Pregnancy, Fertility Implications, and Parental Leave Policies: Where Does Urology Stand?

Author

Orzel J, Holdren C, Grimsby G, Goodridge SD, and Stearns G

Abstract

Objective: To review the existing literature on the status of parenting in urology in the academic urology setting. The field of urology has an ever-growing proportion of women, both in training and in practice. Female residents spend most of their peak fertile years in training and female surgeons at any age experience increased pregnancy complication rates. There is a need to shed light on the unique needs of female urologists who want to have both: a fulfilling surgical career and becoming a parent., Methods: A literature search was conducted on PubMed using combinations of the terms "pregnancy," "urology," "fertility," "infertility," "pregnancy complications," and "parental leave" with one author who reviewed and read the papers., Results: Topics explored included timing of pregnancy, pregnancy complications, parental leave policies, returning to work and lactation policies, and implications of parenting in urology., Conclusion: Progress has been made in the field of urology when it comes to creating spaces that allow for women to pursue both their career and family goals. There is still work that needs to be done to fully support the growing number of female urologists as both parents and physicians., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest to declare., (Copyright © 2025 Elsevier Inc.

Abstract

Fungal pathogens within the urine, specifically Candida species, are a common finding amongst hospitalized patients. Risk factors for the development of candiduria involve patients with indwelling urinary drainage devices, surgical patients, patients undergoing urologic instrumentation, and diabetic patients. Candiduria often presents with an asymptomatic course but can also be a severe life-threatening process. This article will review the epidemiology and risk factors associated with fungal urinary tract infections, and the diagnosis and categorization of these infections along with a review of current medical and surgical treatments for this condition., Competing Interests: Disclosures These authors have nothing to disclose., (Copyright © 2024 Elsevier Inc.

Abstract

Objective: To provide a framework for diversifying the urologic workforce through residency recruitment by integrating principles of diversity, equity, and inclusion (DEI) into program mission and values, application review, and interview process., Materials and Methods: For this narrative review, the Society of Women in Urology Advancing DEI in Urology Residency Recruitment Task Force identified 4 areas for incorporating DEI into residency recruitment: defining a residency program's mission and values, holistic application review, an objective interview process, and implementing DEI principles into a program. Using PubMed and Google Scholar, we performed a non-systematic literature search of articles from January 2014 to January 2024. Search terms included combinations of "diversity", "equity", "inclusion", "residency", "holistic review", "applications", "interviews", and "initiatives". Additional resources were identified through citations of selected articles. Based on findings from these articles, Task Force members made recommendations for best practices., Results: The diversity of practicing urologists is disproportionate to that of the United States population. Emerging evidence demonstrates that DEI efforts in healthcare are associated with better outcomes and reduction in healthcare inequities. We offer strategies for residency programs to integrate DEI initiatives into their recruitment, application review, and interview process. Furthermore, we address extending DEI principles into a program's mission and culture to create an inclusive environment conducive to training and supporting individuals from unique backgrounds., Conclusion: It is critical to recruit and retain diverse talent in urology to improve patient care. We urge residency programs and their supporting institutions to adopt DEI principles into their recruitment efforts., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2024 Elsevier Inc.

Abstract

Introduction: There has been increased interest in using autologous tissues since the Food and Drug Administration banned transvaginal mesh for pelvic organ prolapse in 2019. Our study aims to assess patients' perspective of functional and cosmetic impact on the fascia lata harvest site in patients undergoing fascia lata harvest for the treatment of stress urinary incontinence (SUI)., Methods: This is a prospective survey study of a retrospective cohort of patients who underwent a fascia lata pubovaginal sling between 2017 and 2022. Participants completed a survey regarding the functional and cosmetic outcomes of the harvest site., Results: Seventy-two patients met the inclusion criteria. Twenty-nine patients completed the survey for a completion rate of 40.3%. For functional symptoms, 24.1% (7/29) of patients reported leg discomfort, 10.3% (3/29) reported leg weakness, 10.3% (3/29) reported a bulge, 17.2% (5/29) reported scar pain, 14.8% (4/27) reported scar numbness, and 17.2% (5/29) reported paresthesia at the scar. For cosmetic outcomes, 72.4% (21/29) reported an excellent or good scar appearance. On the PGI-I, 75.9% (22/29) reported their condition as very much better (48.3%, 14/29) or much better (27.6%, 8/29)., Conclusions: The majority of patients reported being satisfied with the functional and cosmetic outcomes of their harvest site as well as satisfied with the improvement in their SUI. Less than 25% of patients report harvest site symptoms, including leg weakness, scar bulging, scar pain, scar numbness, or paresthesia in the scar. This is important in the context of appropriate preoperative discussion and counseling regarding fascia lata harvest., (© 2024 The Authors.

Abstract

An 11-year-old otherwise healthy female presented with renal colic and during computed tomography imaging evaluation, she was found to have a right distal ureteral stone with associated hydroureteronephrosis, medially deviated ureter, and 4-cm solid retroperitoneal mass. The mass was palpable on physical exam and was further categorized with magnetic resonance imaging, ultrasound, and laboratory testing. A multidisciplinary team approach, including pediatric surgery, radiology, oncology, and urology, led to the patient undergoing a right retrograde pyelogram, ureteroscopy with stent placement, and laparoscopic excision of retroperitoneal mass. Her pathology revealed lymphoid hyperplasia with histologic features of Castleman disease., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Abstract

Objectives: Fluoroscopy has significantly improved lead placement and decreased surgical time for implantable sacral neuromodulation (SNM). There is a paucity of data regarding radiation and safety of fluoroscopy during SNM procedures. Our study aims to characterize fluoroscopy time and dose used during SNM surgery across multiple institutions and assess for predictors of increased fluoroscopy time and radiation dose., Methods: Electronic medical records were queried for SNM procedures (Stage 1 and full implant) from 2016 to 2021 at four academic institutions. Demographic, clinical, and intraoperative data were collected, including fluoroscopy time and radiation dose in milligray (mGy). The data were entered into a centralized REDCap database. Univariate and multivariate analysis were performed to assess for predictive factors using STATA/BE 17.0., Results: A total of 664 procedures were performed across four institutions. Of these, 363 (54.6%) procedures had complete fluoroscopy details recorded. Mean surgical time was 58.8 min. Of all procedures, 79.6% were performed by Female Pelvic Medicine and Reconstructive Surgery specialists. There was significant variability in fluoroscopy time and dose based on surgical specialty and institution. Most surgeons (76.4%) were considered "low volume" implanters. In a multivariate analysis, bilateral finder needle testing, surgical indication, surgeon volume, and institution significantly predicted increased fluoroscopy time and radiation dose (p < 0.05)., Conclusions: There is significant variability in fluoroscopy time and radiation dose utilized during SNM procedures, with differences across institutions, surgeons, and subspecialties. Increased radiation exposure can have harmful impacts on the surgical team and patient. These findings demonstrate the need for standardized fluoroscopy use during SNM procedures., (© 2024 Wiley Periodicals LLC.)

Abstract

Introduction: Adjuvant intravesical therapy is recommended for patients with intermediate-risk NMIBC. While intravesical gemcitabine-docetaxel (Gem/Doce) has demonstrated favorable outcomes for high-risk NMIBC, its utility in the intermediate-risk setting is not well described. We report outcomes of Gem/Doce as an adjuvant treatment for intermediate-risk NMIBC., Methods: We retrospectively identified patients with intermediate-risk NMIBC by AUA criteria treated with Gem/Doce following TURBT between 2012 and 2022. Patients received weekly sequential intravesical instillations of 1 g gemcitabine and 37.5 mg docetaxel for 6 weeks. Monthly maintenance of 2 years was initiated if disease-free at first surveillance. The primary outcome was recurrence-free survival (RFS), assessed using the Kaplan-Meier method., Results: The cohort included 77 patients with median follow-up of 26 (IQR 14-50) months. Prior to induction, 67 (87%) patients presented with Ta low-grade (LG) lesions, 3 (3.9%) with Ta high-grade (HG), 5 (6.5%) with TaLG plus focal TaHG, and 2 (2.6%) with T1LG. Thirty-three (43%) patients received previous intravesical therapy including BCG (23), mitomycin (13), and docetaxel monotherapy (12). The 2-year RFS was 71% among all patients. Treatment-naïve patients had superior RFS compared to previously treated patients (P = 0.04); 2-year estimates were 79% and 64%, respectively. Twenty-nine (38%) patients experienced adverse events; all were Grade 1 to 2 except 1 (1.3%) Grade 3 (acute oxygen desaturation). Three (3.9%) patients did not tolerate a full induction course., Conclusions: In this retrospective review of a heterogenous population of patients with intermediate-risk NMIBC, Gem/Doce was an effective and well-tolerated adjuvant therapy. Further prospective evaluation in this setting is needed., Competing Interests: Declaration of Competing Interest IM, VP, JO, RS, SM, and RS have no disclosures.

Abstract

A 46-year-old male presented with a localized left renal mass and underwent an open radical nephrectomy via a midline incision. He recovered uneventfully and was discharged. After one month he reported persistent incisional pain; CT demonstrated heterotopic bone formation under the fascial closure. He underwent resection of calcified preperitoneal fat. Final pathology revealed benign bone tissue. He received a course of celecoxib. The patient developed recurrence of a smaller calcification. He underwent a second resection and was treated with adjuvant radiation. The patient had improvement of pain and no ossification visualized on CT imaging at 1-year follow up., (© 2023 Published by Elsevier Inc.)

Abstract

Introduction: To identify prognostic factors for overall survival (OS) in patients with malignant ureteral obstruction (MUO) from gynecologic malignancy (GM), with the goal of improving patient selection for urinary diversion., Materials and Methods: Retrospective review of 126 patients with MUO from GM at two academic centers from 2011-2019. Factors related to OS identified by Cox regression proportional hazard model. In patients with incomplete survival data (n = 30), hospice was used as a surrogate for death. Multivariate models and receivers operating characteristics (ROC) curves were created for hemoglobin and albumin values., Results: Overall median survival was 6.2 months. On univariate analysis, age at diagnosis, Charlson Comorbidity Index (CCI) ≥ 8, advanced clinical stage, ascites, pleural effusion, albumin, and hemoglobin were associated with poor OS. OS was higher for those receiving ureteral stenting as compared with no intervention. There was no survival difference based on hydronephrosis grade, stent failure (SF), or creatinine at the time of intervention. On multivariate analysis, albumin < 2.85 g/dL and hemoglobin < 9.6 g/dL were predictive of poor OS., Conclusions: OS in patients with MUO due to GM is poor. Several prognostic factors for poor survival including low serum albumin and hemoglobin were identified. Ureteral stenting was associated with improved OS compared to observation, but selection bias likely contributed to this result. Additional studies are needed to clarify this finding. These data can be utilized to counsel patients regarding outcomes after urinary diversion in the setting of MUO and perhaps avoid additional procedures in some of these patients who will not derive meaningful benefit.

Abstract

Analytical methods using the fluorescence properties of bisphenols (BPA, BPF and BPS) and their complexes with β-cyclodextrin and methyl-β-cyclodextrin were developed. The methods were applied for the analysis of thermal paper and canned food. Their performance was compared with a standard HPLC approach with a diode array and fluorescence detections. For comparison purposes, basic validation parameters (linear range, limit of detection, sensitivity, precision) were evaluated. It was concluded the developed methods facilitate fast and cost-effective determination of three bisphenol species in liquid samples, similar to the HPLC performance. They are also environmentally friendly. BPA, BPF and BPS can be routinely determined with the presented approach.

Abstract

Background: Post-SSRI sexual dysfunction (PSSD) is an underrecognized and poorly understood medical condition characterized by sexual dysfunction that persists despite SSRI discontinuation., Objective: We conducted a survey of individuals with PSSD to better characterize this condition and its impact on various quality of life concerns., Methods: Surveys were distributed to an online support group for individuals with PSSD. Surveys assessed medications suspected of causing PSSD and symptoms experienced during and after treatment. Respondents reported the trajectory of their condition, the efficacy of different treatments, and the impact of PSSD on their quality of life., Results: 239 survey responses were included in this study. A majority of respondents had a history of SSRI use (92%) compared to only SNRI or atypical antidepressant use (8%). The overall severity of symptoms improved for 45% and worsened or remained the same for 37% of respondents after discontinuing treatment with serotonin reuptake inhibitors. Only 12% of respondents reported being counseled regarding potential sexual dysfunction while taking antidepressants. The majority rated the effect of PSSD on their quality of life as extremely negative (59%) or very negative (23%)., Conclusion: PSSD can have an overwhelmingly negative impact on quality of life. Currently, it is unclear why certain individuals develop PSSD and there are no definitive treatments for this condition. Further research of PSSD and greater awareness of this condition is needed among prescribers of serotonin reuptake inhibitors to improve patient care.

Abstract

Background: Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) has improved urinary function compared with standard robotic-assisted radical prostatectomy (S-RARP). As RS-RARP spares the dorsal vascular complex, pelvic fascia, and anterior abdominal fascia, it may also lower the incidence of "neglected" postprostatectomy sequelae such as penile shortening, Peyronie's disease, and inguinal hernias., Objective: To determine whether there are patient-perceived differences in penile shortening, Peyronie's disease, and inguinal hernia rates among men undergoing RS-RARP versus S-RARP., Design Setting and Participants: Researchers uninvolved in clinical care and blinded to surgical approach surveyed 60 RS-RARP versus 57 S-RARP men with validated patient-reported items to assess penile shortening, Peyronie's disease, and inguinal hernia sequelae following surgery., Intervention: RS-RARP versus S-RARP., Outcome Measurements and Statistical Analysis: Univariate differences between the two cohorts were analyzed using Student t test. Logistic regression was used to analyze variables associated with postoperative penile shortening. Cox proportional hazards models were used to assess the risk of developing Peyronie's disease and inguinal hernia postoperatively., Results and Limitations: RS-RARP was associated with less patient-reported penile shortening (41.7% vs 64.9%, p  = 0.012), Peyronie's disease (0% vs 8.7%, p  = 0.020), and inguinal hernia (0.0% vs 13.0%, p  = 0.004). In adjusted analyses, RS-RARP (odds ratio [OR] 0.24, 95% confidence interval [CI] 0.09-0.63, p  = 0.004) was associated with lower odds of penile shortening, while a higher body mass index was associated with increased odds of penile shortening (OR 1.13, 95% CI 1.01-1.26, p  = 0.037). RS-RARP was not associated with a decreased risk of Peyronie's disease on Cox proportion hazard model; however, these models are limited due to a limited number of events in our cohort. Limitations include retrospective design, patient-reported outcomes, and small cohorts., Conclusions: RS-RARP is associated with less patient-reported penile shortening and may decrease the risk of Peyronie's disease and postoperative inguinal hernia development. These new findings add to research, showing improved urinary continence and quality of life following RS-RARP; however, a prospective study is needed to validate these findings., Patient Summary: Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) is an evolving surgical technique for prostate cancer treatment, which has shown improved postoperative urinary control compared with the standard technique, likely due to preservation of natural pelvic anatomy. Our findings suggest that the preservation of normal pelvic anatomy during RS-RARP may also reduce the risk of postprostatectomy penile shortening, Peyronie's disease, and inguinal hernia., (© 2020 The Author(s).)

26. Detecting chemical markers to uncover counterfeit rebated excise duty diesel oil.

Author

Orzel J, Krakowska B, Stanimirova I, and Daszykowski M

Abstract

In this study, differences in the chemical compositions of rebated excise duty diesel oil samples that were caused by fuel laundering were investigated. Two possible laundering pathways were simulated using either reduction or adsorption agents in model samples that were spiked with Solvent Yellow 124 and Solvent Red 19. The samples were characterized by their chromatographic fingerprints, which were recorded using gas chromatography coupled with a nitrogen chemiluminescence detector. The collections of fingerprints were further analyzed by discriminant partial least squares and the models with the optimal complexities presented the correct discrimination rates in the range of 69.1%-99.6%, respectively. The most informative fingerprint sections that were associated with the investigated differences were identified using the variable importance in projection, selectivity ratio and uninformative variable elimination methods. The reduced multivariate discriminant models presented a relatively high performance with the correct classification rates in the range of 74.9%-99.8%, respectively. O-toluidine and 2,5-diaminotoluene were identified as potential markers of diesel oil counterfeiting by laundering through a reduction agent., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Abstract

Therapeutic potential of mesenchymal stem cells (MSCs) has been reported consistently in animal models of stroke, with mechanism mainly through immunomodulation and paracrine activity. Intravenous injection has been a prevailing route for MSCs administration, but cell quantities needed when scaling-up from mouse to human are extremely high putting into question feasibility of that approach. Intra-arterial delivery directly routes the cells to the brain thus lowering the required dose. Cell engineering may additionally improve cell homing, further potentiating the value of intra-arterial route. Therefore, our goal was to create microfluidic platform for screening and fast selection of molecules that enhance the docking of stem cells to vessel wall. We hypothesized that our software will be capable of detecting distinct docking properties of naïve and ITGA4-engineered MSCs. Indeed, the cell flow tracker analysis revealed positive effect of cell engineering on docking frequency of MSCs (42% vs. 9%, engineered vs. control cells, p  < 0.001). These observations were then confirmed in an animal model of focal brain injury where cell engineering resulted in improved homing to the brain. To conclude, we developed a platform to study the docking of cells to the vessel wall which is highly relevant for intraarterial cell targeting or studies on neuroinflammation.

Abstract

Selective breeding of laboratory rats resulted in changes of their behavior. Concomitantly, the albino strains developed vision related pathologies. These alterations certainly occurred on the background of modifications in brain morphology. The aim of the study was to assess and compare volumes of major structures in brains of wild-captive, laboratory albino and laboratory pigmented rats. High resolution T2-weighted images of brains of adult male Warsaw Wild Captive Pisula-Stryjek rats (WWCPS, a model of wild type), laboratory pigmented (Brown Norway strain, BN) and albino rats (Wistar strain, WI) were obtained with a 7T small animal-dedicated magnetic resonance tomograph. Volume quantification of whole brains and 50 brain structures within each brain were performed with the digital Schwarz rat brain atlas and a custom-made MATLAB/SPM8 scripts. Brain volumes were scaled to body mass, whereas volumes of brain structures were normalized to individual brain volumes. Normalized brain volume was similar in WWCPS and BN, but lower in WI. Normalized neocortex volume was smaller in both laboratory strains than in WWCPS and the visual cortex was smaller in albino WI rats than in WWCPS and BN. Relative volumes of phylogenetically older structures, such as hippocampus, amygdala, nucleus accumbens and olfactory nuclei, also displayed certain strain-related differences. The present data shows that selective breeding of laboratory rats markedly affected brain morphology, the neocortex being most significantly altered. In particular, albino rats display reduced volume of the visual cortex, possibly related to retinal degeneration and the development of blindness., Competing Interests: The authors have declared that no competing interests exist.

Abstract

The disorders of the glutamatergic neurotransmission have been associated with pathogenesis of autism. In this study we evaluated the impact of the in vivo and ex vivo test methodology on measurements of levels of neurotransmitter amino acids in hippocampus of rats for valproic acid- (VPA) and thalidomide- (THAL) induced models of autism. The main goal was to compare the changes in concentrations of glutamate (Glu), glutamine (Gln) and GABA between both autistic groups and the control, measured in vivo and ex vivo in homogenates. The rat pups underwent three in vivo tests: ultrasonic vocalization (USV), magnetic resonance spectroscopy (MRS) and unilateral microdialysis of the hippocampus. Analyses of homogenates of rat hippocampus were performed using high-performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR) spectroscopy. For the statistical analysis, we performed univariate and multivariate tests. USV test, which is considered in rodents as an indicator of pathology similar to autism, showed decreased USV in VPA and THAL groups. In vivo MRS studies demonstrated increases of Glu content in male rat's hippocampus in VPA and THAL groups, while the microdialysis, which allows examination of the contents in the extracellular space, detected decreases in the basal level of Gln concentrations in VPA and THAL groups. Ex vivo HPLC studies showed that levels of Glu, Gln and GABA significantly increased in male rat's hippocampus in the VPA and THAL groups, while NMR studies showed increased levels of Gln and GABA in the VPA group. Collectively, these results are consistent with the hypothesis suggesting the role of the glutamatergic disturbances on the pathogenesis of autism. For all methods used, the values of measured changes were in the same direction. The orthogonal partial least square discriminant analysis confirmed that both animal models of autism tested here can be used to trace neurochemical changes in the brain.

Abstract

Purpose: To establish a relationship between impairment of the anterograde axonal transport (AAT) in the axons of the retinal ganglion cells and the intraocular pressure (IOP) during aging in mice with hereditary glaucoma., Methods: Quantitative in vivo approach based on manganese enhanced magnetic resonance imaging was developed in order to evaluate AAT in 3-, 6-, and 14-month old DBA/2J mice that develop age-dependent pigmentary glaucoma or age-matched C57Bl/6 mice that do not develop any retinal disease. Unilateral intravitreous administration of MnCl 2 solution was followed 24 h later by MRI performed to obtain spin-lattice relaxation times (T 1 ) for regions of interest encompassing the superior colliculi (SC) and the lateral geniculate nuclei (LGN). From the MRI scans, the estimates of Mn 2+ concentrations in SC and LGN contralateral to the injection site, hence the efficiency of AAT in ON, were obtained. IOP and eye morphology was also monitored., Results: In C57Bl/6 mice, AAT to SC was decreasing with age, 30% decrease was noted between 3 and 14 months. The decrease in axonal transport to LGN was less pronounced in this strain. In 3-month-old DBA/2J mice, axonal transport to SC was 30% lower than in 3-month-old C57Bl/6 mice but no significant decrease was noted in 6-month-old animals. However, a decrease of over 95% in axonal transport both to SC and LGN was noted in 14-month-old DBA/2J mice. DBA/2J mice exhibited a sharp increase in IOP at 6 months, which reversed at 14 months but displayed age-dependent elongation of the eyeball and deepening of the anterior chamber., Conclusion: Failure of AAT to SC of DBA/2J mice during development of pigmentary glaucoma does not follow closely changes in IOP and eye morphology. The relationship between IOP and AAT in optic nerve and tract is complex and may reflect preconditioning mechanism.

Abstract

The performance of the recently proposed excitation-emission fluorescence method was compared to the method using infrared measurements for the evaluation of the antioxidant properties of intact samples and extracts that had been obtained from tomato pastes. The oxygen radical absorbance capacity assay (ORAC) was applied in order to estimate the antioxidant capacity of the extracts, while the Folin-Ciocalteu reagent was adopted for the evaluation of the total phenolic content. The optimal extraction conditions for tomato pastes (three minutes of sonication under 80°C) were determined using the central composite design. Chemometric models such as the partial least squares regression and its N-way variant were further constructed in order to predict the antioxidant capacity or total phenolic content of the samples using either the IR or fluorescence spectra. The prediction errors that were obtained for the total antioxidant content were evaluated as the Trolox equivalents from the ORAC assay and were found to be equal to 2.011 (14.21%) for the fluorescence and 2.426 (17.15%) for the IR spectra, respectively. The prediction errors of the total phenolic content expressed as gallic acid equivalents were 0.067 (10.78%) for the fluorescence and 0.033 (5.36%) for the IR spectra, which were used as independent variables in the regression models., (Copyright © 2015 Elsevier B.V.

32. Detection of discoloration in diesel fuel based on gas chromatographic fingerprints.

Abstract

In the countries of the European Community, diesel fuel samples are spiked with Solvent Yellow 124 and either Solvent Red 19 or Solvent Red 164. Their presence at a given concentration indicates the specific tax rate and determines the usage of fuel. The removal of these so-called excise duty components, which is known as fuel "laundering", is an illegal action that causes a substantial loss in a government's budget. The aim of our study was to prove that genuine diesel fuel samples and their counterfeit variants (obtained from a simulated sorption process) can be differentiated by using their gas chromatographic fingerprints that are registered with a flame ionization detector. To achieve this aim, a discriminant partial least squares analysis, PLS-DA, for the genuine and counterfeit oil fingerprints after a baseline correction and the alignment of peaks was constructed and validated. Uninformative variables elimination (UVE), variable importance in projection (VIP), and selectivity ratio (SR), which were coupled with a bootstrap procedure, were adapted in PLS-DA in order to limit the possibility of model overfitting. Several major chemical components within the regions that are relevant to the discriminant problem were suggested as being the most influential. We also found that the bootstrap variants of UVE-PLS-DA and SR-PLS-DA have excellent predictive abilities for a limited number of gas chromatographic features, 14 and 16, respectively. This conclusion was also supported by the unitary values that were obtained for the area under the receiver operating curve (AUC) independently for the model and test sets.

Abstract

Models to predict the total antioxidant capacity (TAC) of rooibos tea infusions from their chromatographic fingerprints and peak table data (content of individual phenolic compounds), obtained using HPLC with diode array detection, were developed in order to identify potential antioxidant markers. Peak table data included the content of 12 compounds, namely phenylpyruvic acid-2-O-glucoside, aspalathin, nothofagin, isoorientin, orientin, ferulic acid, quercetin-3-O-robinobioside, vitexin, hyperoside, rutin, isovitexin and isoquercitrin. The TAC values, measured using the oxygen radical absorbance capacity (ORAC) and DPPH radical scavenging assays, could be predicted from the peak table data or the chromatographic fingerprints (prediction errors 9-12%) using partial least squares (PLS) regression. Prediction models created from samples of only two production years could additionally be used to predict the TAC of samples from another production year (prediction errors<13%) indicating the robustness of the models in a quality control environment. Furthermore, the uninformative variable elimination (UVE)-PLS method was used to identify potential antioxidant markers for rooibos infusions. All individual phenolic compounds that were quantified were selected as informative variables, except vitexin, while UVE-PLS models developed from chromatographic fingerprints indicated additional antioxidant markers, namely (S)-eriodictyol-6-C-glucoside, (R)-eriodictyol-6-C-glucoside, aspalalinin and two unidentified compounds. The potential antioxidant markers should be validated prior to use in quality control of rooibos tea., (Copyright © 2014 Elsevier B.V. All rights reserved.)

34. Simultaneous determination of Solvent Yellow 124 and Solvent Red 19 in diesel oil using fluorescence spectroscopy and chemometrics.

Author

Abstract

Differences in tax levels for diesel oil stimulate the illegal removal of characteristic diazo compounds purposely added to designate its possible usage. In order to reduce the losses in the national income, there is a strong need to develop a sensitive and cost-effective analytical procedure for the detection of this illegal action. In this study, we describe a novel analytical approach for a qualitative and quantitative determination of two diazo compounds (Solvent Yellow 124 and Solvent Red 19) that are usually added to diesel oil. The methodology proposed combines the use of excitation-emission matrix fluorescence spectroscopy as an analytical technique and partial least squares regression as a multiple modeling tool. With this new methodology, relatively low root mean square errors of prediction (for independent set of test samples) that are equal to 0.223 for Solvent Red 19 and 0.263 for Solvent Yellow 124, were obtained and the results were stable, which were indicated by an analysis performed after 48 and 96 h. The methodology is also nondestructive and allows for (i) simultaneous detection of diesel oil additives, (ii) determination of satisfactory limits of detection (0.048 and 0.042 mg L(-1) for Solvent Red 19 and Solvent Yellow 124, respectively), and (iii) obtaining of considerably low relative standard deviations of 2.33% for Solvent Yellow 124 and of 3.23% for Solvent Red 19 in comparison with the existing norm level., (Copyright © 2012 Elsevier B.V.

Abstract

The nucleus reticularis pontis oralis (RPO) is a reticular structure important for the regulation of paradoxical sleep (PS). However, the data concerning the relation between the RPO and the main tonic indicator of PS, hippocampal theta rhythm, are contradictory: although electrical or cholinergic stimulation of the RPO evoked well-synchronized theta activity, the electrolytic lesion of the structure had no effect on theta. In our experiment, the effect of procaine injections into different parts of the RPO on the electrical activity of the hippocampus, as well as on tail pinch-elicited hippocampal theta rhythm was assessed in urethanized rats. Power spectral analysis was performed using a Fast Fourier Transform routine in 1-Hz and 3-Hz bands between 0.6 and 12 Hz frequency. We have found that unilateral procaine inactivation of neurons in the caudal part of the RPO blocked the sensory-elicited theta rhythm. The same injection into the rostral RPO either had no effect or evoked long-lasting episodes of theta rhythm without sensory stimulation. These results suggest functional diversity of the parts of the RPO in mechanisms underlying production of hippocampal theta.
