RESUMO
INTRODUCTION: Age-related white matter hyperintensities (ARWMHs) on brain magnetic resonance imaging have been associated with lower urinary tract symptoms/dysfunction (LUTS/LUTD), namely overactive bladder (OAB) and detrusor overactivity. We aimed to systematically review existing data on the association between ARWMH and LUTS and which clinical tools have been used for this assessment. MATERIALS AND METHODS: We searched PubMed/MEDLINE, Cochrane Library, and clinicaltrials.gov (from 1980 to November 2021) and considered original studies reporting data on ARWMH and LUTS/LUTD in patients of both sexes aged 50 or above. The primary outcome was OAB. We calculated the unadjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) for the outcomes of interest using random-effects models. RESULTS: Fourteen studies were included. LUTS assessment was heterogeneous and mainly based on the use of nonvalidated questionnaires. Urodynamics assessment was reported in five studies. ARWMHs were graded using visual scales in eight studies. Patients with moderate-to-severe ARWMHs were more likely to present with OAB and urgency urinary incontinence (UUI; OR = 1.61; 95% CI: 1.05-2.49, p = 0.03), I2 = 21.3%) when compared to patients with similar age and absent or mild ARWMH. DISCUSSION AND CONCLUSIONS: High-quality data on the association between ARWMH and OAB is scarce. Patients with moderate to severe ARWMH showed higher levels of OAB symptoms, including UUI, when compared to patients with absent or mild ARWMH. The use of standardized tools to assess both ARWMH and OAB in these patients should be encouraged in future research.

INTRODUCTION AND HYPOTHESIS: The International Consultation on Incontinence Questionnaire (ICIQ) Bladder Diary (BD) is a standardized and validated diary, developed in the English language, designed to assess lower urinary tract symptoms (LUTS) in men and women. This study reports the translation, cross-cultural adaptation and validation process of this diary to the Portuguese language. METHODS: After translation and back-translation of the ICIQ-BD to Portuguese, 140 urologic patients were asked to fill in this 3-day diary as well as the Overactive Bladder questionnaire Short Form (OABqSF) and a questionnaire evaluating the difficulties in filling out the ICIQ-BD. A subset of 60 patients filled out a second diary with/without LUTS treatment in between (30 patients in each group). In addition, content validity, internal consistency, criterion and construct validity were tested. RESULTS: The Portuguese version of the ICIQ-BD showed adequate internal consistency (Cronbach's alpha of 0.78), and patients reported few difficulties in filling out this tool, answering most commonly 1 on a 1-6 scale of difficulty. Excellent test-retest reliability and responsiveness of the diary were observed when comparing the first diary to a second completed 2-6 weeks later. Criterion validity was also confirmed, given the good correlation with the OABqSF (Pearson's 0.386-0.447). Finally, construct validity was established through statistically significant concordance between data obtained in the BD with generally accepted theories. CONCLUSION: The present version of the ICIQ-BD is the first bladder diary successfully validated in the Portuguese language. It is a suitable and standardized tool for scientific research and diagnostic assessment of LUTS in adult men and women.

AIMS: Local anesthesia protocols for intradetrusor onabotulinum toxin A (BoNTA) injection lack standardization. We aimed to determine if an alkalinized lidocaine solution is more effective than lidocaine only. METHODS: Patients of both genders aged 18 or above enlisted for intradetrusor BoNTA injection (idiopathic, neurogenic, and bladder pain syndrome) were included in a double-blinded randomized controlled trial after obtaining their informed consent. All participants filled a bladder diary and a urine culture was performed. Subjects were randomized 1:1 to Protocol A (20 ml 2% lidocaine + 10 ml 8.4% sodium bicarbonate) or Protocol B (20 ml 2% lidocaine + 10 ml 0.9% saline solution). A Numeric Rating Scale (0-10) was used to assess the level of pain immediately after the procedure (primary endpoint). Secondary endpoints included pain after 1 h, urinary tract infection, acute urinary retention, and hematuria related to the procedure. RESULTS: A total of 116 patients were randomized. Baseline characteristics (age, sex, indication, and bladder diary parameters) of patients in Group A and B were similar. Pain scores at the end of the procedure were significantly lower with the alkalinized solution (Protocol A and B, respectively, 2.37 ± 0.31 vs. 4.44 ± 0.36, p < .01). No differences were observed 1 h after treatment (Protocol A and B, respectively, 0.54 ± 0.17 vs. 0.69 ± 0.19, p = .487). The only adverse event reported was mild-to-moderate self-limited hematuria in 15.4% of patients. CONCLUSIONS: The use of an alkalinized lidocaine solution has proven to be significantly superior to lidocaine only as local anesthesia before intradetrusor BoNTA injection, suggesting that this may be considered a first-line option.

For therapeutic proteins, the currently established standard development path generally does not foresee biotransformation studies by default because it is well known that the clearance of therapeutic proteins proceeds via degradation to small peptides and individual amino acids. In contrast to small molecules, there is no general need to identify enzymes involved in biotransformation because this information is not relevant for drug-drug interaction assessment and for understanding the clearance of a therapeutic protein. Nevertheless, there are good reasons to embark on biotransformation studies, especially for complex therapeutic proteins. Typical triggers are unexpected rapid clearance, species differences in clearance not following the typical allometric relationship, a mismatch in the pharmacokinetics/pharmacodynamics (PK/PD) relationship, and the need to understand observed differences between the results of multiple bioanalytical methods (e.g., total vs. target-binding competent antibody concentrations). Early on during compound optimization, knowledge on protein biotransformation may help to design more stable drug candidates with favorable in vivo PK properties. Understanding the biotransformation of a therapeutic protein may also support designing and understanding the bioanalytical assay and ultimately the PK/PD assessment. Especially in cases where biotransformation products are pharmacologically active, quantification and assessment of their contribution to the overall pharmacological effect can be important for establishing a PK/PD relationship and extrapolation to humans. With the increasing number of complex therapeutic protein formats, the need for understanding the biotransformation of therapeutic proteins becomes more urgent. This article provides an overview on biotransformation processes, proteases involved, strategic considerations, regulatory guidelines, literature examples for in vitro and in vivo biotransformation, and technical approaches to study protein biotransformation. SIGNIFICANCE STATEMENT: Understanding the biotransformation of complex therapeutic proteins can be crucial for establishing a pharmacokinetic/pharmacodynamic relationship. This article will highlight scientific, strategic, regulatory, and technological features of protein biotransformation.

BACKGROUND: Insulin-like growth factor 1 (IGF-1)(7) is a key mediator of growth hormone (GH) action and a well-characterized biomarker of GH abuse. Current immunoassays for IGF-1 suffer from poor concordance between platforms, which makes comparison of results between laboratories difficult. Although previous work has demonstrated good interlaboratory imprecision of LC-MS/MS methods when plasma is supplemented with purified proteins, the interlaboratory imprecision of an endogenous protein in the nanogram-per-milliliter concentration range has not been reported. METHODS: We deployed an LC-MS/MS method to quantify serum IGF-1 in 5 laboratories using 5 different instruments and analyzed 130 healthy human samples and 22 samples from patients with acromegaly. We determined measurement imprecision (CV) for differences due to instrumentation, calibration curve construction, method of calibration, and reference material. RESULTS: Instrument-dependent variation, exclusive of digestion, across 5 different instrument platforms was determined to be 5.6%. Interlaboratory variation was strongly dependent on calibration. Calibration materials from a single laboratory resulted in less variation than materials made in individual laboratories (CV 5.2% vs 12.8%, respectively). The mean imprecision for 152 samples between the 5 laboratories was 16.0% when a calibration curve was made in each laboratory and 11.1% when a single-point calibration approach was used. CONCLUSIONS: The interlaboratory imprecision of serum IGF-1 concentrations is acceptable for use of the assay in antidoping laboratories and in standardizing results across clinical laboratories. The primary source of variability is not derived from the sample preparation but from the method of calibration.

RATIONALE: Insulin-like growth factor-I is one of the biomarkers used to detect growth hormone administration prohibited in human sport. Current testing approaches for IGF-I rely on commercial immunoassays, which may change from time to time requiring complex revalidation. Mass spectrometry (MS)-based approaches often rely on enzymatically digesting the protein and measuring specific peptide concentrations. In order to reinforce the current available methodology for IGF-I testing, a reliable and equally sensitive MS method is required for the analysis of intact protein using small sample volumes (<25 µL). METHODS: IGF-I was extracted from human serum samples by a simple protein precipitation procedure. Separation was achieved via nano-ultrahigh-performance liquid chromatography and MS analysis was conducted by nano-electrospray ionisation triple-quadrupole mass spectrometry in the selected reaction monitoring mode using a stable-isotope-labelled internal standard. RESULTS: A six-point calibration curve ranging from 50 to 1000 ng/mL of human IGF-I in rat serum was used to establish instrument response. The method provided a limit of quantification of 50 ng/mL, with intra- and inter-day precision ≤5% and intra- and inter-day accuracy ≥95%. CONCLUSIONS: A quantitative method was developed for the quantification of intact IGF-I in human serum samples. The data generated provided important information for the development of a new reference method for the growth hormone biomarker test and helped create a reliable system for monitoring peptide hormones in individual athletes, a possible extension to the athlete biological passport system. Nano-electrospray has here been shown to be sufficiently robust for routine use in an analytical laboratory, allowing for the analysis of minute sample volumes.

Intravesical bacillus Calmette-Guérin (BCG) immunotherapy is recommended for non-muscle-invasive bladder cancer after transurethral resection. BCG-associated musculoskeletal adverse events are rare. We report two cases of BCG reactive arthritis that were unusually severe and refractory. These describe two male patients who presented with polyarthritis after BCG exposure. Ultrasonography-guided glucocorticoid injections, high-dose systemic glucocorticoids and the institution of sulfasalazine were required for achievement of remission. Bacillus Calmette-Guérin reactive arthritis can present as polyarthritis of small and medium joints or as mono-oligoarthritis of asymmetrical ankles and knees, frequently associated with tenosynovitis and enthesitis. The mechanism by which BCG promotes arthralgia and arthritis is poorly understood. The most well-accepted theory is that the BCG antigens migrate to different peripheral tissues, including the joints. There is also a lack of knowledge regarding risk factors, with possible genetic factors playing a role. As the two presented cases show, BCG-induced reactive arthritis should be considered in the differential diagnosis of arthritis and refractory tenosynovitis in BCG-exposed patients.

The main objective of this work was to quantify and characterize the major indoor air contaminants present in different stages of a municipal WWTP, including microorganisms (bacteria and fungi), carbon dioxide, carbon monoxide, hydrogen sulfide ammonia, formaldehyde, and volatile organic compounds (VOCs). In general, the total bacteria concentration was found to vary from 60 to >52,560 colony-forming units (CFU)/m(3), and the total fungi concentration ranged from 369 to 14,068 CFU/m(3). Generally, Gram-positive bacteria were observed in higher number than Gram-negative bacteria. CO(2) concentration ranged from 251 to 9,710 ppm, and CO concentration was either not detected or presented a level of 1 ppm. H(2)S concentration ranged from 0.1 to 6.0 ppm. NH(3) concentration was <2 ppm in most samples. Formaldehyde was <0.01 ppm at all sampling sites. The total VOC concentration ranged from 36 to 1,724 µg/m(3). Among the VOCs, toluene presented the highest concentration. Results point to indoor/outdoor ratios higher than one. In general, the highest levels of airborne contaminants were detected at the primary treatment (SEDIPAC 3D), secondary sedimentation, and sludge dehydration. At most sampling sites, the concentrations of airborne contaminants were below the occupational exposure limits (OELs) for all the campaigns. However, a few contaminants were above OELs in some sampling sites.

Drug-drug interaction (DDI) assessments are well defined in health authority guidelines for small molecule drugs, and US Food and Drug Administration (FDA) draft guidance is now available for therapeutic proteins. However, there are currently no regulatory guidelines outlining DDI assessments for therapeutic peptides, which poses significant uncertainty and challenges during drug development for this heterogenous class of molecules. A cross-industry peptide DDI working group consisting of experts from 10 leading companies was formed under the sponsorship of the European Federation of Pharmaceutical Industries and Associations. We aimed to capture the range of DDI studies undertaken for peptide drugs by (i) anonymously surveying relevant companies involved in peptide drug development to better understand DDI study type/timing currently performed and (ii) compiling a database containing in vitro / clinical DDI data from submission packages for recently approved peptide drugs. Our analyses highlight significant gaps and uncertainty in the field. For example, the reported timing of in vitro peptide DDI studies, if performed, vary substantially across responding companies from early research to phase III. Nearly all in vitro cytochrome P450 / transporter inhibition studies reported in the survey were negative. For the few positive hits reported, no clinical follow-up studies were performed, questioning the clinical relevance of these findings. Furthermore, available submission packages reveal DDI likelihood is low for peptides >2 kDa, making it reasonable to adopt a risk-based approach during drug development for larger peptides. By benchmarking the landscape of peptide DDI activities across the industry, we set the stage for future discussions with health authorities on harmonizing peptide DDI approaches.

This clinical case aimed to achieve two main objectives. The first was to determine if the use of only calcium phosphosilicate bone graft as a regeneration material (with no autologous bone added) on a severe vertical and horizontal mandibular defect would allow enough bone to be obtained to enable the placement of dental implants. The second objective was to determine histologic characteristics of the regenerated site after a healing period of 10 months.

OBJECTIVES: Transurethral resection of the prostate (TURP) remains one of the goldstandard surgical treatments for benign prostatic hyperplasia/lower urinary tract symptoms. The usefulness of a complete adenoma resection is questionable, with studies reporting no impact of the amount of resected tissue on surgical outcomes, irrespective of prostate volume. The aim of this study was to assess whether in less obstructed patients a less extensive TURP may be considered. MATERIALS AND METHODS: Retrospective analysis of 185 men undergoing TURP in one university hospital. Retrieved data included pre-operative prostate volume and Qmax, as well as resected prostate weight and post-operative Qmax. Patients were divided in two groups according to pre-operative Qmax < 10mL/s and ≥ 10 mL/s. RESULTS: A correlation was found between absolute resected prostate weight and post-operative Qmax in the group of patients with pre-operative Qmax < 10 mL/s (r2 = 0.038, p = 0.032), independently of the pre-operative prostate volume. This association was neither observed in the group of patients with pre-operative Qmax ≥ 10 mL/s (r2 = -0.033, p = 0.796) nor in whole population analysis (r2 = 0.019, p = 0.064). Likewise, in the group of patients with pre-operative Qmax < 10 mL/s, the improvement in Qmax was correlated with absolute resected weight and percentage of prostate resected weight (r2 = 0.036, p = 0.037 and r2 = 0.040, p = 0.029, respectively). None of these correlations was found in the group of patients with pre-operative Qmax ≥ 10 mL/s (r2 = 0.009, p = 0.463 and r2 = -0.018, p = 0.294, respectively). CONCLUSIONS: Patients with pre-operative Qmax ≥ 10 mL/s may do well with less profound prostate resections, whereas patients with lower pre-operative Qmax seem to benefit from a complete adenoma resection.

Background: Different treatments have been proposed for Fibromyalgia, but only few studies have compared their effects on multiples outcomes over time. Objective: The objective of this study was to investigate the effects of aquatic physiotherapy (AP) or a health education program (HEP) in a sample of women with Fibromyalgia (FM). Methods: Forty-six women with FM, aged between 25 and 60 years old, whose BMI was less than 30, were assigned to either AP (27 women) or HEP (19 women) groups in a blind randomized clinical trial lasting eleven weeks. Pain (McGill Pain questionnaire), fatigue (Piper Fatigue Scale-Revised), functional capability (Fibromyalgia Impact questionnaire), anxiety (Beck Anxiety Inventory), depression (Beck Depression Inventory) and quality of sleep (Pittsburgh Sleep Quality Index) data were collected at baseline, after six weeks and post intervention. Two-factor mixed-model analysis of variance (ANOVAs) were used to examine the effects of the treatment on each outcome variable. Results: The AP and HEP interventions showed statistically significant within-group differences on all outcome measures except reducing the pain. Between-group differences was statistically significant only for impact of FM on the participant's life [F(1.82,80.41) = 31,99; p ≤ 0.01] indicating that patients receiving HEP experienced a greater decrease in FIQ than those treated with AP. Conclusion: The findings do not allow to affirm that one intervention is superior to the other for the treatment of people with FM. Future studies should investigate whether the combination of HEP and PA can be effective and long-lasting.

INTRODUCTION: Pancreas angiosarcoma is a very aggressive malignant neoplasm. The symptoms are nonspecific and it is usually diagnosed at an advanced stage, which confers a poor prognosis. PRESENTATION OF CASE: We present a 56-year-old woman with abdominal epigastric pain and nausea. The abdominal CT-scan showed a 7â¯cm mass within the head of the pancreas and the pathology and immunochemistry analysis were positive for pancreas angiosarcoma. Intra-operatively the tumor was irresectable. DISCUSSION: Pancreas angiosarcoma is an extremely rare neoplasm with non-specific diagnosis. The histology has a wide range of presentations and immunohistochemistry is required. The surgery appears to be the only effective treatment. CONCLUSION: We report the seventh case of pancreas angiosarcoma in the English literature. Despite it's irresectability, the patient was asymptomatic two months after surgery, initiating chemotherapy with paclitaxel, with good tolerance.
RESUMO
In the last decade, environmental risks associated with wastewater treatment plants (WWTPs) have become a concern in the scientific community due to the absence of specific legislation governing the occupational exposure limits (OEL) for microorganisms present in indoor air. Thus, it is necessary to develop techniques to effectively inactivate microorganisms present in the air of WWTPs facilities. In the present work, ultraviolet light A radiation was used as inactivation tool. The microbial population was not visibly reduced in the bioaerosol by ultraviolet light A (UVA) photolysis. The UVA photocatalytic process for the inactivation of microorganisms (bacteria and fungi, ATCC strains and isolates from indoor air samples of a WWTP) using titanium dioxide (TiO2 P25) and zinc oxide (ZnO) was tested in both liquid-phase and airborne conditions. In the slurry conditions at liquid phase, P25 showed a better performance in inactivation. For this reason, gas-phase assays were performed in a tubular photoreactor packed with cellulose acetate monolithic structures coated with P25. The survival rate of microorganisms under study decreased with the catalyst load and the UVA exposure time. Inactivation of fungi was slower than resistant bacteria, followed by Gram-positive bacteria and Gram-negative bacteria. Graphical abstract Inactivation of fungi and bacteria in gas phase by photocatalitic process performed in a tubular photoreactor packed with cellulose acetate monolith structures coated with TiO2.

The modification of titanate nanotubes (TiNT) with nitrogen (NTiNT) was accomplished through impregnation method. TiNT were synthesized via hydrothermal treatment of titania powders in NaOH solution at 130 °C for 48 h. The obtained samples were characterized by UV-Vis absorption spectroscopy, Brunauer-Emmett-Teller (BET) surface area, XRD, TEM, XPS, and TG analysis. Structure, morphology, composition, and visible light absorption property of nitrogen-modified TiO2 nanotubes are found to depend on the nitrogen content and not on the calcination temperature for the range used in this work. The photocatalytic activity of these nanotubes was investigated for the degradation of methylethylketone (MEK) and hydrogen sulfide (H2S) under ultraviolet and solar light radiation. MEK is very resistant to photocatalytic degradation with the prepared materials;, however, the results show that modification of the TiNT with nitrogen in a proportion of 1 to 1 (TiNT to urea weight ratio) and calcination at 400 °C lead to materials with high photocatalytic activity under ultraviolet radiation and moderate photocatalytic activity under solar radiation for degradation of H2S.

Objective: To analyze meaning in life, satisfaction with life, and the influence of sociodemographic variables in Brazilians with Spinal Cord Injury (SCI). This was a quantitative, cross-sectional, and descriptive study. Participants: Adults with traumatic SCI. Methods: The data were collected through the Survey Monkey platform using the Meaning in Life Questionnaire and the Satisfaction With Life Scale; the sample was composed of adults 18 years old or older with Traumatic SCI. Results: Most of the participants were male (75.5%), with a mean age of 36.22. The average score on the Satisfaction With Life Scale was 21.26, which corresponds to the Slightly satisfied category. The mean scores, respectively, for search and presence of meaning in life were 22.61 and 25.32, indicating that most participants find life meaningful even though they don't explicitly search for meaning. There were significant associations between satisfaction with life and the meaning in life. Conclusion: In the rehabilitation process for people with Traumatic SCI, the assessment of satisfaction and the meaning of life must be managed together along with other psychological variables. Considering the complex life context of people suffering from a Traumatic SCI, there is a need for both holistic and individualized understanding during the rehabilitation process

Cellulose acetate monoliths (CAM) were used as the substrate for the deposition of TiO2 films to produce honeycombed photoactive structures to fill a tubular photoreactor equipped with a compound parabolic collector. By using such a setup, an efficient single-pass gas-phase conversion was achieved in the degradation of n-decane, a model volatile organic compound. The CAM three-dimensional, gas-permeable transparent structure with a rugged surface enables a good adhesion of the catalytic coating. It also provides a rigid structure for packing the tubular photoreactor, and maximizing the illuminated catalyst surface. The efficiency of the photocatalytic oxidation (PCO) process on n-decane degradation was evaluated under different operating conditions, such as feeding concentration (73 and 146 ppm), gas stream flow rate (73, 150, and 300 mL min(-1)), relative humidity (3 and 25 %), and UV irradiance (18.9, 29.1, and 38.4 WUV m(-2)). The results show that n-decane degradation by neat photolysis is negligible, but mineralization efficiencies of 86 and 82 % were achieved with P25-CAM and SG-CAM, respectively, for parent pollutant conversions above 95 %, under steady-state conditions. A mass transfer model, considering the mass balance to the plug-flow packed photoreactor, and PCO reaction given by a Langmuir-Hinshelwood bimolecular non-competitive two types of sites equation, was able to predict well the PCO kinetics under steady-state conditions, considering all the operational parameters tested. Overall, the performance of P25-CAM was superior taking into account mineralization efficiency, cost of preparation, surface roughness, and robustness of the deposited film.

We present a case of a 67-year-old patient with a history of augmentation ileocystoplasty 31 years ago following genitourinary tuberculosis. Radiological investigations performed due to asymptomatic microscopic haematuria revealed three contrast-enhancing polyps within the neobladder. The patient had enterocystoprostatectomy and histopathological examination of the neobladder revealed mucinous adenocarcinoma in all three polyps, together with a prostatic adenocarcinoma Gleason 7 (3+4). After adjuvant chemotherapy and 1 year of follow-up, he had no sign of clinical or radiological recurrence. Taking into consideration this rare case, we discuss the development of malignant tumours after the incorporation of intestinal segments in a urinary tract reconstruction, showing what relationship exists between secondary neoplastic growth, the primary disease and the type of urinary diversion utilised.
