Normally, horse urine is light-dark yellow and can be thread-like due to its high mucin content. The physiological pH value is 7–9, the urine specific gravity is 1.020–1.050 g/ml. The macroscopic examination of the urine provides important information. Dependent on the amount of fluid intake the colour of urine can range from almost colourless to dark brown discoloration. Furthermore, the colour depends on the substances that are excreted with the urine. The presence of blood in the urine is pathological and called haematuria. In this case, the urine is so heavily contaminated with blood that even blood clots can be excreted. However, if the urine is only reddish in colour, haematuria must be distinguished from haemoglobinuria or myoglobinuria. To differentiate it macroscopically alone can be difficult so that horse owners may wrongly report that their horse has passed bloody urine. The occurrence of haematuria involves a wide range of differential diagnoses that must be systematically clarified. It is essential to differentiate between systemic diseases and those of the urinary system. In the first place a general examination should be carried out. Then it should be followed by a hematological examination and an analysis of the urine. If the urine is collected spontaneously, the midstream urine is most suitable for further investigations, as contaminations have been flushed out before collection. If these investigations result that there is a disease of the urinary tract, transrectal palpation and transrectal and transabdominal sonographic examination should also be performed. Further diagnostic procedures such as urethroscopy and cystoscopy are also indicated. In the following case report, a twenty-three-year-old Oldenburg gelding with macrohematuria was presented. Cystoscopy revealed a mass whose surface was uneven, rough and partly covered with fibrin and blood clots. A transendoscopic biopsy was requested. Depending on the consistency and location of the growth, sampling may be difficult. A temporary perineal urethrotomy facilitates biopsy collection while providing the opportunity for direct visualization of the urinary bladder contents. Perineal urethrotomy is a well-known method in male patients with obstructive urinary tract disease for temporary diversion of urine. In the following case report, this method was performed to obtain a sufficiently large biopsy specimen using uterine biopsy forceps. The results of the mentioned examinations resulted in the diagnosis of a transitional cell carcinoma (TCC) in the urinary bladder. Primary bladder tumors are very rare in horses and often produce a reactive inflammatory change. The urinary tract is lined with transitional cell epithelium, so transitional cell carcinoma can occur in any section, but most commonly in the bladder wall in horses. It must be clarified whether there are already metastases. Depending on the stage, spread and size of this malignant tumour, therapy can be considered. Surgical removal of a bladder tumour in horses is difficult due to the anatomical location of the urinary bladder in the abdominal cavity and the tendency of these tumors to invade the bladder wall. However, various therapeutic approaches have been described in the literature. Authors report chemotherapy, irradiation with a diode laser or surgical ablation of the cancerous tissue and oral application of piroxicam. Pronounced clinical symptoms are only seen at an advanced stage of the tumour, so that the disease is diagnosed mostly too late for a curative approach. However, early diagnosis is crucial for the prognosis and therefore a detailed diagnostic investigation is required in the case of microhaematuria. Because of the late stage of the disease and the poor prognosis the patient of the current report was euthanized. [ABSTRACT FROM AUTHOR]

Acute and persistent dehydration can cause reduced renal perfusion that can potentially lead to the development of acute kidney injury (AKI). Current biomarkers for renal function such as serum creatinine and blood urea nitrogen (BUN) might not be ideal for early detection of renal damage due to their late increase at a loss of approximately 3/4 of the nephron function. Renal function analysis (RFA) helps to localize the damage of the particular nephron segment. However, it is usually used in animals with clinical signs of renal disease instead of for early prediction of renal damage. In the present study, parameters of the RFA were measured in dehydrated patients four times within 48 hours after admission. We tested for an association between dehydration levels, parameters of the RFA and outcome in order to identify risk factors for AKI and choose early adequate medical intervention. Included in the study were 29 horses, divided into three groups according to their dehydration levels (mild dehydration = 6–8 % dehydration; moderate dehydration = 8–10 %; severe dehydration and shock = >10 % dehydration). Urine and serum were collected at admission and at three additional time-points until 48 hours after admission. Results of individual parameters of the RFA were compared to results of a commercial urine stick. The following parameters of the RFA were selected for further analysis: The association of serum creatinine, BUN, urine specific gravity (uSG), fractional excretion of sodium (FENa+), urine total protein (uTP) and urinary GGT (uGGT)/ urinary Creatinine (uCreatinine) ratio were analyzed by Kruskal-Wallis-Test. The correlations between all parameters were measured by Kendall Tau-b Test. At T0 13.8 % (4/29) horses had increased serum creatinine concentration, while elevated BUN concentrations were observed in 24.1 % (7/29) horses. 42.9 % (12/28) horses had increased uSG. FENa+ and uGGT/uCreatinine ratio were elevated both in 18.5 % (5/27). 17.9 % (5/28) of horses had uTP above the reference range. Two of these patients could be verified by urine sticks. Increased leukocytes were found by sediment examination in 7.1 % (2/28) horses, one of them was also verified by urine stick. 3.6 % (1/28) horses had increased erythrocytes in the urine which didn’t show by the urine stick. Only the serum creatinine concentration had a significant association with dehydration levels (P = 0.001). Serum creatinine and BUN as well as serum creatinine and uGGT/uCreatinine ratio had moderate correlations at admission (r = 0.417; r = 0.361 respectively). In the meantime, uSG had moderate correlation with FENa+ and uGGT/uCreatinine ratio (r = -0.590; r = -0.328 respectively). Although two horses with the highest FENa+ survived to discharge, FENa+ had a significant association with the outcome of the patients (P = 0.047). None of the patients developed clinical signs of AKI during their hospitalization. Serum creatinine was the only biomarker in the present study that had an association with dehydration levels. In the present study, the selected parameters of the RFA were not suitable to detect early changes in renal function induced by dehydration. [ABSTRACT FROM AUTHOR]

Diese Arbeit behandelt die statistische Auswertung von den möglichen Tumormarkern CA 19-9 in Blutproben, LYVE1, TFF1, REG1A, REG1B und Kreatinin in Urinproben für Bauchspeicheldrüsenkrebs. Unterschieden wurde zwischen den Diagnosegruppen Kontrolle (Negativ Kontrolle), gutartige hepatobiliäre Erkrankung und Pankreaskarzinom. Zusätzlich wurden innerhalb dieser Gruppen getestet, ob es eine mögliche Signifikanz zwischen dem Geschlecht und Altersgruppen der Proben gibt. Die Ergebnisse nach der Auswertung lassen aussagen, dass die Tumormarker, LYVE1, TFF1, REG1A und REG1B im Vergleich zur Kontrolle erhöht sind und sich diese statistisch als Marker eignen würden. Bei den Pankreaskarzinom Proben konnte man unterschiedliche Werte von LYVE1, Kreatinine und CA-19-9 zwischen den jüngeren Teilnehmer und den älteren Teilnehmer in dieser Studie statistisch bestimmen. Das Geschlecht könnte eine relevante Rolle bei Pankreaskarzinom spielen, worauf aber in dieser Studie nicht näher eingegangen wurde. This paper deals with the statistical evaluation of the possible tumor markers CA 19-9 in blood samples, LYVE1, TFF1, REG1A, REG1B and creatinine in urine samples for pancreatic cancer.Distinctions were made between the diagnostic groups of control (negative control), benign hepatobiliary disease, and pancreatic cancer. In addition, within these groups were tested whether there is a possible significance between the sex and age groups of the samples. The results after evaluation suggest that the cancer markers, LYVE1, TFF1, REG1A and REG1B are elevated compared to control and these would be statistically suitable as markers. In the pancreatic cancer samples, different levels of LYVE1, creatinine and CA-19-9 could be statistically determined between the younger participants and the older participants in this study. Gender might play a relevant role in pancreatic cancer, which was not addressed in this study.

Die amyotrophe Lateralsklerose (ALS) ist die häufigste Motoneuronerkrankung im Erwachsenenalter. Sie zeichnet sich durch den Verlust des ersten und zweiten Motoneurons aus und ist derzeit nicht kurativ therapierbar. Aufgrund der heterogenen Symptomatik und fehlenden Biomarkern wird die Diagnosestellung verzögert. Ziel dieser Arbeit ist es daher, Kombinationen von laborchemischen Markern zu finden, die mit hoher Präzision vorhersagen können, ob es sich um einen an ALS erkrankten Patienten oder gesunden Probanden handelt, um die Diagnosestellung zu erleichtern. Einbezogen wurden Parameter des Blutbilds, der Klinischen Chemie, der Proteindiagnostik, der Schilddrüse, des Liquors und des Urins. Es erfolgte ein Vergleich sowie Regressionsanalysen in der Routine erhobener Labordaten von insgesamt 566 an ALS erkrankten Patienten und nicht an ALS erkrankten Kontrollpersonen, die zwischen 2009 und 2016 in den Rehabilitationskliniken Ulm (RKU) stationär behandelt wurden. Für 30 Marker aus Laborprofilen von insgesamt 262 an ALS erkrankten und nicht erkrankten Personen erfolgte zudem eine kombinatorische Analyse basierend auf Verfahren des maschinellen Lernens. Es unterschieden sich die Werte für das mittlere korpuskuläre Erythrozytenvolumen (MCV), die mittlere korpuskuläre Hämoglobinkonzentration (MCHC), Natrium, Kreatinin, Creatinkinase und Gesamtprotein signifikant zwischen Patienten- und Kontrollkollektiv. Regressionsanalysen konnten weiterhin zeigen, dass bei Betrachtung mehrerer Parameter in einem Modell der Prognoseerfolg zur Zuordnung der Gruppe der Erkrankten verbessert wird. Mithilfe verschiedener Verfahren des maschinellen Lernens im Rahmen einer kombinatorischen Analyse konnte anhand der Daten mit einer Vorhersagegenauigkeit von ≥73,2% auf das Vorliegen der Erkrankung ALS rückgeschlossen werden. Als aussagekräftigster Kombinationsmarker ist der Serumspiegel der Creatinkinase zu nennen. In den erstellten Modellen waren weitaus weniger als die 30 Parameter, die in die Analyse miteinbezogen wurden, zur Erstellung der Prognose notwendig. Diese Arbeit konnte folglich zeigen, dass Algorithmen, basierend auf maschinellem Lernen, eine Unterstützung in der laborchemischen Diagnostik der ALS darstellen können. Die Ergebnisse sollten in einer prospektiven Langzeitstudie unter standardisierten Bedingungen reevaluiert und mit Beginn und Progression der Erkrankung korreliert werden. Zur Verbesserung der Vorhersagegenauigkeit kann die Berücksichtigung klinischer Kriterien hilfreich sein.

In 2017, the German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re-evaluated the maximum workplace concentration (MAK value) of 1,4-dichlorobenzene [106-46-7]. If the MAK value of 2 ml 1,4-dichlorobenzene/m3 (12 mg/m3) is not exceeded, prenatal toxic effects are not to be expected. Therefore, 1,4-dichlorobenzene was classified in Pregnancy Risk Group C. In 2019, the biological tolerance value (BAT value) of 10 mg 2,5-dichlorophenol/l urine was derived in correlation to the MAK value. Therefore, Pregnancy Risk Group C is also valid for the BAT value. Adhering to the BAT value of 10 mg 2,5-dichlorophenol/l urine, prenatal toxic effects are not to be expected.

The working group “Analyses in Biological Materials” of the Permanent Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area developed and verified the presented biomonitoring method. This analytical method is used to determine selenite and selenate in urine, which are separated by anion-exchange chromatography and subsequently detected by inductively coupled plasma-mass spectrometry (ICP‑MS). Calibration is performed using standard solutions, which are prepared in pooled urine, processed, and analysed analogously to the samples. The analytical method allows for the sensitive and precise determination of selenite and selenate without interferences by other selenium species. The low limits of quantitation enable the determination of very low urinary concentrations of selenite or selenate. However, selenite and selenate do not normally contribute substantially to total selenium content in urine.

The working group “Analyses in Biological Materials” of the Permanent Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area developed and verified the presented biomonitoring method.The analytical method described herein allows for the sensitive and specific determination of 2,6‑difluorobenzoic acid (2,6‑DFBA) in the urine of individuals occupationally exposed to 2,6‑difluorosubstituted benzoylurea compounds. 2,6‑DFBA is determined by gas chromatography with mass-spectrometric detection (GC‑MS) after derivatisation. To this end, urine samples are mixed with an internal standard, acidified, and purified using solid-phase extraction (SPE). The samples are derivatised with N‑methyl-N‑tert‑butyldimethylsilyltrifluoroacetamide (MTBSTFA) and the analyte concentration is quantified by GC‑MS. The internal standard used is 5‑bromo-2‑fluorobenzoic acid. Calibration is performed using standard solutions prepared in pooled urine.

The working group “Analyses in Biological Materials” of the Permanent Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area developed and verified the presented biomonitoring method. This analytical method is used to determine relevant weakly polar or ionic organic selenium species in urine. They are separated by reversed-phase chromatography and subsequently detected using inductively coupled plasma-mass spectrometry (ICP‑MS). Calibration is performed using standard solutions prepared in pooled urine, which are processed and analysed analogously to the samples. The analytical method allows for the selective and sensitive determination of seven selenium species without interferences by other species. The limits of quantitation for the determination of the individual species lie between 0.18 μg/l and 0.34 μg/l urine (as selenium) and are thereby sufficient to measure exposure levels which exceed the background exposure of the general population.

The working group “Analyses in Biological Materials” of the Permanent Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area developed and verified the presented biomonitoring method.With the procedure described below, the following lysmeral metabolites are determined in urine: hydroxylysmerylic acid, 4‑tert-butylbenzoic acid (TBBA), tert-butylhippuric acid (TBHA), lysmerylic acid, and lysmerol. Following the addition of the deuterated internal standards (TBBA‑d 13 , lysmerylic acid‑d 8 , and lysmerol‑d 8 ) to 1 ml of urine, an enzymatic cleavage is carried out using β‑glucuronidase. The samples are then subjected to liquid-liquid extraction with dichloromethane. The extracts are evaporated to dryness and derivatised with 3‑nitrophthalic anhydride. The analysis is performed by UPLC‑MS/MS following negative electrospray ionisation (ESI−).

The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re-evaluated n-heptane [142-82-5] in 2020 and derived a biological tolerance value (BAT value) considering heptane-2,5-dione in urine to characterise the internal exposure. The BAT value is based on the correlation between external and internal exposure and represents an equivalent of the maximum workplace concentration (MAK value) of n-heptane in biological material, taking into account central nervous effects and peripheral neurotoxicity as critical systemic effects. Mainly data from two human experimental exposure studies were used to derive the BAT value. In a more recent study, 20 non-smoking volunteers were exposed at rest to n-heptane up to 500 ml/m3. Data on renal excretion of the n-heptane metabolite heptane-2,5-dione were similar to those obtained by another working group. The few available workplace studies were not suitable to derive a BAT value. An analysis of the pooled data from both experimental studies resulted in an extrapolated urinary concentration of 235 ��g heptane-2,5-dione/l urine after eight hours of exposure to the current MAK value of 500 ml/m3.

- Abstract
About 15% of the women and 10% of the men past the age of 65 years suffer from urinary incontinence. In most cases, accurate history taking can help differentiate between urge incontinence, stress incontinence and overflow incontinence, and is essential in choosing the appropriate treatment. Initial diagnostic testing can be conducted by the general practitioner, especially tests to exclude urinary tract infections or to rule out an overactive bladder. Patient education on changes to fluid intake and voiding habits as well as advice on suitable incontinence products are important first steps in the management of urinary continence. Also, drug treatment can be initiated in general practice. Patients with refractory urinary incontinence, particularly those who did not respond to anticholinergic medication, should be referred to a urologist for further evaluation since there may be an underlying tumour or other disorder of the bladder that is causing the incontinence.

A misregulation between oxidative processes and the antioxidative defense of the organism can lead to oxidative stress. Here Isoprostanes can be formed from arachidonic acid by non-enzymatic oxidative processes. From the multitude of isoprostanes the isomer IPG F2α is regarded as a stable marker substance and gold standard for the analysis of oxidative stress in vivo. The purpose of this study was to examine whether an increase of IPG F2α concentrations in urine after dives is measurable due to oxygen exposure in divers as a model for the generation of oxidative stress. For the selective determination of the target analyte IPG F2α a quantitative LC-DMS-MS/MS method was established and validated for the first time. The extraction types (Solid Phase Extraction and Supported Liquid Extraction) tested during the method development showed strong suppression effects for the matrix urine. It was therefore questionable whether the low concentrations of IPG F2α suspected in the diver samples could be reliably measured. In order to reduce matrix effects, chromatography was modified to achieve better separation of the suppressing matrix components. This made time-consuming and error-prone sample preparation unnecessary. By simply diluting the samples with a solution of the internal standard (dilute & shoot), a clear signal of the target analyte IPG F2α could be measured in each urine. The application of the validated method to urine samples of divers (n = 234) showed that the IPG F2α concentration per creatinine in the median immediately after a dive was significantly increased by +6 % (mean +10 %) compared to the initial value before physical exercise under oxygen exposure. For the first time this increase was correlated with the oxygen load responsible for it. A significant linear dependence between the increase of the measured values and the oxygen load during the dives was observed. In each sample an additional signal of the isomer 15(R)-IPG F2α, clearly separated from the target analyte, was measured. Therefore, this isomer was evaluated as a potential alternative marker of oxidative stress. A lower and not significant increase of the concentration per creatinine of +1 % in the median (mean +4 %) after a dive was observed. Thus, the isomer 15(R)-IPG F2α was a less sensitive marker of oxidative stress than the target analyte IPG F2α. The correlation of the increase in concentration with the oxygen load, which was also carried out here for the first time, showed a significant linear correlation between the increase in measured values and the oxygen load due to the dives. Using the diver urines (n = 234), measurements with and without differential mobility spectrometry (DMS) were compared. It was examined whether the measurement method used could also be used with LC-MS/MS systems without a DMS-module. The use of DMS resulted in +3 % higher IPG F2α readings. This statistically significant difference was not relevant for practical application, especially for before-and-after comparisons of samples of the same individual. The developed method could also be used without DMS add-on equipment. Nevertheless, the DMS-module showed a higher selectivity in the measurement series and the signal-to-noise ratio (S/N) improved by a factor of 3.5 compared to measurements without DMS.

Objective: The cystogram after retropubic radical prostatovesiculectomy (RRP) examines the condition of the anastomosis region. There is no clear temporal recommendation for the determination of urine extravasation in cases of early removal of the catheter. This study investigates the macroscopic and microscopic examination of the bladder catheter urine after RRP.Patients and Methods: The catheter urine of 110 patients after RRP was macroscopically and microscopically examined and compared with the results of transrectal ultrasound and cystogram with regard to urine extravasation.Results: The examination of cloudy or bloody catheter urine indicated an extravasation in 32 of 33 cases (positive predictive value 97%; sensitivity 74%), for clear urine, there was sufficient anastomosis in 66 of 77 cases without any extravasation (negative predictive value 86%; specificity 99%). By performing a microscopic urine analysis unremarkable anastomosis was predicted only in 23 of 67 cases, which leads to a specificity of 34%. This shows that microscopic urine sediment is an inappropriate instrument to evaluate the anastomotic region.Conclusion: In cases of macroscopic pathological urine findings, further diagnostics are not recommended; in 97% of the cases, extravasation is expected. The macroscopic urine examination sets a trend for other examinations like cystogram or dynamic transrectal ultrasound (dTRUS). [ABSTRACT FROM AUTHOR]- Published

Introduction: The number of noninvasive diagnostic tests for bladder cancer has increased tremendously over the last years with a large number of experimental and commercial tests. Comparative analyses of tests for diagnosis, follow-up, and recurrence detection of bladder cancer were performed retrospectively as well as prospectively, unicentrically, and multicentrically.Methods: An analysis of multicentric studies with large patient numbers compared with our own Kiel Tumor Bank data is presented. The Kiel Tumor Bank data looked prospectively at 106 consecutive bladder tumor patients from the year 2006. Special focus was put on urine cytology as a reference test, as well as the commercial NMP 22 Bladder Chek.Results: The analysis of the NMP 22 Bladder Chek showed an overall sensitivity of 69% for all tumor grades and stages, with a specificity of 76%. Comparison to multicentric data with an overall sensitivity of 75% for all tumor grades and stages, with a specificity of 73%, showed results similar to those in the literature. Urine cytology showed a comparable overall sensitivity of 73% for all tumor grades and stages, with a specificity of 80%.Conclusions: A large number of noninvasive tests for bladder cancer follow-up with reasonable sensitivity and specificity can currently be used. Because of limited numbers of prospective randomized multicentric studies, no single particular marker for bladder cancer screening can be recommended at this point in time.

In the clarification of hematuria and subsequent treatment, a high specificity is expected from urinary cytology when no tumor is present, because false positive results lead to unnecessary diagnostic measures. The aim of this study was to investigate different disturbing factors to determine the specificity of urinary cytology and whether the specificity can be increased by cytometry. Out of 150 patients with no malignant disease, 125 were affected by the following disturbing factors: urinary infection, urolithiasis, transurethral electroresection, utilisation of hypo-osmolar flushing solution or administration of contrast agents. In 5 patients who were diagnosed with urinary infection or urolithiasis, the urine was falsely cytologically determined to be tumor positive, an error which was corrected by cytometric analysis. Therefore, cytometric analysis should be carried out in patients in whom a tumor has been cytologically diagnosed in order to increase the specificity of urinary cytology. [ABSTRACT FROM AUTHOR]

The development of urine diagnostics has been well examined historiographically. However, its importance for science studies has not yet been stressed enough. As a diagnostic tool, that survived many centuries, it underwent several changes. Therefore, its use for science studies is exemplarily displayed in this paper. An attempt is made by the authors to combine questions of the history of science with methods from the cognitive sciences. The reader is introduced into an interdisciplinary approach aiming at the visualisation of scientific shifts to make a deeper analyse of such shifts possible. Lawrence Barsalou proposed a dynamic frame model to represent cognitive structures. This model is used to reconstruct scientific revolutions (in the sense of Thomas Kuhn) as well as barely noticeable shifts (in the sense of Ludwik Fleck's shifting thought styles). The value of this approach for the history of medicine in general and the history of uroscopy in special is discussed. [ABSTRACT FROM AUTHOR]

This paper describes a feeding study with 7 pigs, which were fed with deoxynivalenol contaminated oats at a level of 0.23 mg/kg body mass/day over 16 experiment days. The contamination level of consumed feed was 14.4 mg DON/kg in the ration. The parallel control group of 7 pigs were fed with DON free oats. Urine samples were taken each two days. The content of DON and DOM-1 (de-epoxy deoxynivalenol) in urine was determined. The mean concentration of DON in urine of animals in trial group was 580 μg/l, whereas DOM-1 32 μg/l. In einer Fütterungsstudie wurden Schweine in zwei Gruppen zu je 7 Tieren mit kontaminiertem (Versuchsgruppe) und unbelastetem Getreide (Kontrollgruppe) gefüttert. Die Gesamtkonzentration von DON in der Ration der Versuchsgruppe war 14.4 mg/kg. Die Tagesdosis betrug in der Versuchsgruppe 0.23 mg/kg Körpermasse und Tag. Der Versuch dauerte 16 Tage, jeden zweiten Tag wurde der Spontanharn gesammelt. Die Urinproben wurden auf DON und DOM-1 analysiert. Für die Analyse der Urinproben bzw. des Futtermittels wurde eine HPLC-MS Methode verwendet. [ABSTRACT FROM AUTHOR]

Chyluria, a symptom that is very rare in the western world, describes the excretion of chyle into the urogenital system. We present the case of a 61-year-old woman with a severe form of nonparasitic chyluria. We were able to detect the fistula due to a newly developed diagnostic combination of Sudan III red with ureterorenoscopy. Prior to this, we had performed a lymphoscintigraphy twice without detecting the lymphorenal fistula, although lymphoscintigraphy is the current diagnostic standard. This is the first case report of severe, nonparasitic chyluria.
