Scale of Emotional Development - Short: reliability and validity in adults with intellectual disability. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2023; 67:1046-1060. [PMID: 37661289 DOI: 10.1111/jir.13080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 08/01/2023] [Accepted: 08/08/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND Intellectual disability (ID) is often associated with delays in emotional development (ED). The Scale of Emotional Development - Short (SED-S) was developed to assess the level of ED and to adapt treatment and care accordingly. METHODS In a sample of 724 adults from five study sites in three countries, a confirmatory factor analysis with a one-factor model was conducted on the entire dataset as well as in different subgroups. Furthermore, internal consistency was investigated using Cronbach's alpha. RESULTS The confirmatory factor analysis indicated that a single-factor model fits the SED-S data well. The subgroup analyses revealed good model fit, regardless of the severity of ID and irrespective of sex or the presence of autism spectrum disorder or psychiatric disorders. Internal consistency was excellent for the entire sample (Cronbach's alpha = 0.93) and various subgroups (0.869-0.938). CONCLUSION The results of this study suggest that the SED-S is psychometrically sound and can be used to assess the level of ED in adults with ID.

Efficient Unitary Designs with a System-Size Independent Number of Non-Clifford Gates. COMMUNICATIONS IN MATHEMATICAL PHYSICS 2022; 397:995-1041.

Abstract
Many quantum information protocols require the implementation of random unitaries. Because it takes exponential resources to produce Haar-random unitaries drawn from the full n-qubit group, one often resorts to t-designs. Unitary t-designs mimic the Haar-measure up to t-th moments. It is known that Clifford operations can implement at most 3-designs. In this work, we quantify the non-Clifford resources required to break this barrier. We find that it suffices to inject O ( t 4 log 2 ( t ) log ( 1 / ε ) ) many non-Clifford gates into a polynomial-depth random Clifford circuit to obtain an ε -approximate t-design. Strikingly, the number of non-Clifford gates required is independent of the system size - asymptotically, the density of non-Clifford gates is allowed to tend to zero. We also derive novel bounds on the convergence time of random Clifford circuits to the t-th moment of the uniform distribution on the Clifford group. Our proofs exploit a recently developed variant of Schur-Weyl duality for the Clifford group, as well as bounds on restricted spectral gaps of averaging operators.

The impact of emotional development in people with autism spectrum disorder and intellectual developmental disability. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2020; 64:946-955. [PMID: 33043998 DOI: 10.1111/jir.12785] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Revised: 09/08/2020] [Accepted: 09/15/2020] [Indexed: 05/08/2023]
Abstract
BACKGROUND Intellectual developmental disabilities (IDDs) and autism spectrum disorders (ASDs) are developmental conditions, which may also be associated with impairments in emotional development (ED). ED can be assessed using the Scale of Emotional Development - Short (SED-S), a five-stage model consisting of eight domains, which allows to study the relationship between ASD and ED in people with IDD. METHODS In this retrospective study, the level of ED was compared in 327 adults with IDD with [n = 83; mean age 38.3 years; level of IDD: mild (6), moderate (21), severe (45) and profound (11)] and without [n = 244, mean age 36.9 years; level of IDD: mild (67), moderate (73), severe (68) and profound (36)] ASD. The discriminative ability of the SED-S was determined by a regression in a training and a validation sample. RESULTS The level of ED correlated with the severity of IDD (rs = -.654) and the presence of ASD (rs = -.316). People with additional ASD showed lower levels of ED compared with those with IDD only (mean reference ages 7-18 vs 19-36 months). The developmental profiles were equally balanced in ASD and IDD-only. A regression analysis revealed three domains ('Relating-to-Peers', 'Differentiating-Emotions', and 'Regulating-Affect') to be useful for ASD assignment (AUC > 0.70, sensitivity 0.76-0.80, specificity 0.62-0.63). CONCLUSIONS In people with IDD, additional ASD was associated with delays in ED, which may be considered in diagnostics, treatment and care.

Abstract
OBJECTIVE Phenylethyl resorcinol (PR) has been used widely in the personal care industry as a novel skin lightening ingredient. Surprisingly, there is only limited information describing the physicochemical properties of this active. Therefore, the primary objective of this study was to perform a comprehensive characterization of PR. A secondary objective was to investigate the delivery of this molecule to mammalian skin. METHODS Phenylethyl resorcinol was characterized using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and nuclear magnetic resonance (NMR). A new high-performance liquid chromatographic (HPLC) method for analysis of PR was developed and validated. The log P (octanol water partition coefficient), value, solubility and short-term stability of PR in a series of vehicles were also determined using HPLC. The evaporation of the selected vehicles was examined using dynamic vapour sorption (DVS). The permeation profiles of PR were investigated under finite dose conditions in porcine and human skin. RESULTS The melting point of PR was determined to be 79.13 °C and the measured log P (octanol water partition coefficient) at 21 °C was 3.35 ± 0.03. The linearity of the HPLC analytical method was confirmed with an r2 value of 0.99. Accuracy of the method was evaluated by average recovery rates at three tested concentrations, and the values ranged from 99 to 106%. The limit of detection (LOD) and limit of quantification (LOQ) were 0.19 and 0.57 μg mL-1 , respectively. The solubility of PR in PG, DMI, glycerol was within the range of 367 to 877 mg mL-1 . The stability of PR in tested solvents was also confirmed by the 72 h stability studies. From the DVS studies, 70-125% of applied formulations were recovered at 24 h. The permeation through porcine skin at 24 h ranged from 4 to 13 μg cm-2 , while the corresponding amounts of PR delivered through human skin were 2 to 10 μg cm-2 . CONCLUSION The physicochemical properties of PR confirm it is suitable for dermal delivery. In this study, propylene glycol was the most promising vehicle for PR delivery to human skin. Future work will expand the range of vehicles studied and explore the percutaneous absorption from more complex formulations.

Abstract
Vascular changes play an important role in the pathogenesis of claw horn disruption lesions in cattle. The aim of the study was to measure arterial blood flow in the hind limbs of German Holstein cows with claw horn disruption lesions. A 10-MHz linear transducer was used to assess blood flow in the interdigital artery in the dorsal pastern region in the hind limbs of 11 non-lame and 33 lame German Holstein cows in which lameness was scored clinically. Qualitative and quantitative blood flow parameters were compared in affected limbs and unaffected contralateral hind limbs in lame cows and in the hind limbs of lame cows and non-lame cows. A pulsed-wave Doppler signal suitable for analysis was obtained in 78 of 88 limbs (33 affected and contralateral limbs, 22 limbs of control cows). Blood flow curve types 1 and 2 were predominant in the hind limbs of lame cows. Vessel diameter, end-diastolic velocity, and blood flow rate were significantly greater in lame cows than in non-lame cows and were numerically greater in moderately lame cows than in mildly lame cows. The differences in the qualitative and quantitative parameters between lame and non-lame cows were most likely caused by inflammation of the pododerm. The role of weight distribution between the paired hind limbs and the existence of claw horn disruption appeared to have an effect on the differences in local circulation in the affected and unaffected contralateral hind limbs in lame cows.

Abstract
Ultrashort laser pulses allow for the in-volume processing of glass through non-linear absorption, resulting in permanent material changes and the generation of internal stress. Across the manifold potential applications of this technology, process optimization requires a detailed understanding of the laser-matter interaction. Of particular relevance are the deposition of energy inside the material and the subsequent relaxation processes. In this paper, we investigate the spatio-temporal evolution of free carriers, energy transfer, and the resulting permanent modifications in the volume of glass during and after exposure to femtosecond and picosecond pulses. For this purpose, we employ time-resolved microscopy in order to obtain shadowgraphic and interferometric images that allow relating the transient distributions to the refractive index change profile. Whereas the plasma generation time is given by the pulse duration, the thermal dynamics occur over several microseconds. Among the most notable features is the emergence of a pressure wave due to the sudden increase of temperature and pressure within the interaction volume. We show how the structure of the modifications, including material disruptions as well as local defects, can be directly influenced by a judicious choice of pulse duration, pulse energy, and focus geometry.

Abstract
BACKGROUND People with intellectual disabilities (ID) have a shorter life expectancy and higher mortality rate and more often suffer from various physical and mental disorders (WHO: 3-4 times more often than the general population). Obesity is an important risk factor for various disorders. This cross-sectional study examined the body weight and its risk factors in a clinical population of adults with ID. METHODS The prevalence of underweight, normal weight, and overweight was determined using the body mass index (BMI) for 633 patients of an outpatient clinic for people with ID and mental disorders. A multiple logistic regression analysis was used to assess factors for alterations in body weight. RESULTS Approximately one out of two men and two out of three women with ID and mental disorders were overweight. Adults with mild and moderate ID, female gender, increasing age, Down's syndrome, behavioral disorders, and a less supported living situation were associated with a higher rate of obesity. People with dementia and autism spectrum disorders showed a lower rate of obesity. CONCLUSION Young women with ID and mental disorders were particularly at risk for obesity. The respective factors may support the development of specific prevention programs to reduce the risk of overweight and thereby lead to better mental and physical health in people with ID.

Abstract
BACKGROUND Local circulatory disturbances have been implicated in the development of foot disorders in cattle. The goals of this study were to evaluate the suitability of the interdigital artery in the pastern region in both hind limbs using pulsed-wave (PW) Doppler ultrasonography and to investigate quantitative arterial blood flow variables at that site in dairy cows. An Esaote MyLabOne ultrasound machine with a 10-MHz linear transducer was used to assess blood flow in the interdigital artery in the pastern region in both hind limbs of 22 healthy German Holstein cows. The cows originated from three commercial farms and were restrained in a standing hoof trimming chute without sedation. RESULTS A PW Doppler signal suitable for analysis was obtained in 17 of 22 cows. The blood flow profiles were categorised into four curve types, and the following quantitative variables were measured in three uniform cardiac cycles: vessel diameter, pulse rate, maximum systolic velocity, maximum diastolic velocity, end-diastolic velocity, reverse velocity, maximum time-averaged mean velocity, blood flow rate, resistance index and persistence index. The measurements did not differ among cows from the three farms. Maximum systolic velocity, vessel diameter and pulse rate did not differ but other variables differed significantly among blood flow profiles. CONCLUSIONS Differences in weight-bearing are thought to be responsible for the normal variability of blood flow profiles in healthy cows. The scanning technique used in this report for evaluation of blood flow in the interdigital artery appears suitable for further investigations in healthy and in lame cows.

Abstract
The aim of the present study was to investigate the impact of crucial process parameters, i.e. of light and temperature conditions, during the preparation of St. John's wort (SJW, Hypericum perforatum L.) Arachis oil macerates. Extracts were prepared according to a standardized protocol over a period of 28 days. For this purpose, flowering tops of H. perforatum were macerated with Arachis oil (drug extract ratio, DERnative 1:4) under different light and temperature conditions. Spectrophotometric measurements were carried out to quantitate naphthodianthrones and to characterize extract color in the CIE L*C*h° system. Moreover, individual plant secondary metabolites were screened by UHPLC-DAD-MSn measurements following liquid-liquid extraction of the oil macerates with methanol. For quantitation purposes, the chromatographic method was validated using reference standards. This methodology allowed the separation of up to 25 constituents in oily and methanolic SJW extracts, covering hydroxycinnamic acids, flavanols, proanthocyanidins, flavonol glycosides, flavonol aglyca, biflavones, bisanthraquinone glycosides, naphthodianthrones and phloroglucinols. Lowest naphthodianthrone contents were determined in oil macerates recovered at 5 °C, whereas highest amounts were detected upon extraction at 50 °C (both under the exclusion of light). Color shades of the oil macerates differed markedly, revealing e. g. a*-values ranging from -4.6±0.3 to 42.5±0.3. The flavonoids quercetin, kaempferol and I3, II8-biapigenin as well as the phloroglucinols hyperforin and adhyperforin could be simultaneously detected and quantitated in all oil macerates. Contents of these constituents varied noticeably between macerates prepared under different conditions (quercetin 14.7±1.2 to 21.8±0.6 μg/g, kaempferol 3.0±0.1 to 5.4±0.4 μg/g, I3, II8-biapigenin 4.4±0.2 to 7.4±0.4 μg/g, hyperforin 52.6±46.0 to 451.4±24.9 μg/g, adhyperforin 6.9±5.7 to 74.5±7.1 μg/g). These results confirm that the quality of the resulting plant extracts is largely determined by the respective process parameters, i.e. especially temperature and light conditions, and thus must be thoroughly chosen and monitored to obtain tailor-made preparations.

Abstract
BACKGROUND The Critical Incident Reporting System (CIRS) is a tool for employees to report anonymously of near misses. Its efficiency and improvement of safety is proved by many studies. Our department introduced CIRS in 2009 and it is used frequently. As the number of reports decreased over time we asked for factors responsible for the reduced use. METHODS All employees had access to CIRS and have been trained in several courses of instruction. Accomplished results and consequences were published in biannual newsletters. In 2014 we initiated an anonymous employee attitude survey to ask for their experience and satisfaction with CIRS. RESULTS 88 near misses were reported since 2009. 44 (50%) reports were classified as RS1, 34 (38.6%) as RS2, and 10 (11.4%) as RS3. No RS4 reports were notified. Most reports concerned problems with administration of medication (n=26; 29.5%) and problems with technical devices (n=18; 20.5%). 75 (83%) of our employees participated in the survey. 64 (86.5%) discerned that CIRS is anonymous. 31 (41.9%) reported already a near miss. Of note, two-third didn't realize an improvement following their report. On the other hand, only half of the pollees stated to read the newsletter. CONCLUSION Even if efficiency and advantages of CIRS are proved and undeniable, sufficient and perpetual feedback of results and improvements developed by the CIRS team and regular trainings of the employees are mandatory for the success of CIRS.

Abstract
Purpose: Vasodilatation is a frequent side effect of radiographic contrast media, partially due to a direct effect on vascular smooth muscles. Our purpose was therefore to examine any possible implication of the cyclic adenosine monophospate (cAMP) and cyclic guanosine monophosphate (cGMP) pathways in contrast media induced vasorelaxation. Material and Methods: Isolated segments of swine renal arteries were precontracted with 10 μM phenylephrine and relaxed with iomeprol before and after blockade of the cAMP and cGMP pathways. Results: 80 mM and 160 mM of iomeprol significantly relaxed about 52% and 68% of the precontracted arterial rings, respectively. 10 μm of IBMX, a phosphodiesterase inhibitor, did not increase the relaxant effect of 80 mM iomeprol but increased the relaxations induced by 400 nM forskolin by about 1.9 times (which stimulates the production of cAMP), and by 1 μm sodium nitroprusside (which stimulates the production of cGMP). 1 μm of H89 (an inhibitor of the cAMP-dependent protein kinase), was able to reduce the relaxation induced by 4 μM forskolin by about 2.5 times but had no significant effect on the relaxation induced by 160 mM iomeprol. 10 μM of ODQ (an inhibitor of the soluble guanylate cyclase), could reduce the relaxation induced by 10 μM of SNP but not the one induced by 160 mM iomeprol. Moreover, the absence of endothelial cells did not alter the relaxation induced by iomeprol. Conclusion: The activation of the cAMP and cGMP pathways are not involved in the in vitro relaxation induced by iomeprol in swine renal arteries.

Abstract
BACKGROUND Deterioration in bone health is one of the presenting symptoms of Multiple Myeloma (MM), a cancer of plasma cells. As a consequence of this condition, patients suffer bone pain and bone damage and report cancer-related fatigue, resulting in deterioration in their quality of life. Evidence in patients with solid tumours shows promise for the positive effects of physical activity on quality of life. However, in the case of patients with MM a better understanding of the association between physical fitness and quality of life factors is still required. Therefore, this cohort study aims to objectively and longitudinally assess activity and fitness levels in patients with MM in order to explore their role in bone health, fatigue and quality of life for this patient population. METHODS/DESIGN The study is a prospective cohort study of MM patients in remission to assess physical activity, fatigue and bone health. Clinical markers of health, self-reported measures of psychological and physical well-being, and lifestyle behaviours are assessed at baseline, 3, 6 and 12 months. At each time point, patients complete cardiopulmonary exercise testing (CPET) along with a series of objective tests to assess physical fitness (eg accelerometry) and a number of self-report measures. A complementary qualitative study will be carried out in order to explore patients' desire for lifestyle advice and when in their cancer journey they deem such advice to be useful. DISCUSSION This study will be the first to prospectively and longitudinally explore associations between physical fitness and well-being, bone health, and fatigue (along with a number of other physical and clinical outcomes) in a cohort of patients with MM with the use of objective measures. The findings will also help to identify time points within the MM pathway at which physical activity interventions may be introduced for maximum benefit.

Abstract
Muscle injuries frequently occur during sport and are one of the commonest injuries. The diagnosis and treatment of muscle injuries impose high demands on medical treatment, in order to ensure successful regeneration and a rapid return to sport. Most of the injuries can be treated conservatively, as skeletal muscles have a high endogenous capacity for repair and regeneration. Conservative treatment includes initial on-field therapy. This is known as the "RICE" principle and is common and recommended for initial treatment for most sports injuries. The primary therapy target is to reduce pain, swelling and bleeding and thus to limit the initial inflammatory process and prevent further damage. During the first days after injury, brief immobilization helps to reduce the re-injury rate and accelerates the formation of granulation tissue. There are many possible additional treatments, including intramuscular injections, manipulation of the sacroiliac joint or rehabilitation programs, including stretching and strengthening. If the acute treatment phase is complete after 3 to 5 days, more active treatment, including trunk stabilisation, stretching and strengthening, can be started gradually. Despite their high prevalence, there have only been a few studies on the treatment and management of these injuries. The aim of this manuscript is to review the literature on the classification, pathobiology and treatment strategies for muscle injuries.

Abstract
BACKGROUND Identification of Autism Spectrum Disorder (ASD) in persons with intellectual disability (ID) is challenging but essential to allow adequate treatment to be given. This study examines whether the combination of two ASD screening instruments specifically developed for persons with ID, namely, the Diagnostic Behavioral Assessment for ASD-Revised (DiBAS-R) and the Autism Checklist (ACL), improves diagnostic accuracy when used in combination compared to the application of the single instrument. METHOD A clinical sample of adults with ID who are suspected of having ASD (N =148) was assessed using two ID specific screening scales (DiBAS-R and ACL). The diagnostic validity of the single instruments and of their combination was assessed. RESULTS While both instruments showed acceptable diagnostic validity when applied alone (DiBAS-R/ACL: sensitivity: 75%/91%; specificity: 75%/75%; overall agreement: 75%/83%), specificity increased when two positive screening results were used (88%), and sensitivity increased (95%) when at least one positive screening result was used. CONCLUSIONS Different combinations of the ASD screening instruments DiBAS-R and ACL lead to improvements in sensitivity and specificity. The complementary use of the ACL in addition to the sole use of the DiBAS-R improves overall accuracy.

Abstract
Background This study aimed to examine whether fear of cancer recurrence (FCR) was related to two important health behaviours (physical activity and smoking) in a large sample of colorectal cancer patients. Methods Ten thousand nine hundred sixty nine patients, diagnosed in 2010–11, and in remission in 2013, completed the ‘Living with and Beyond Colorectal Cancer’ survey. The survey included purpose‐designed questions on fear of recurrence (‘I have fear about my cancer coming back’), demographics, treatment and health variables. Physical activity (PA) was recorded as number of days per week doing at least 30 min of brisk activity, and smoking status was reported. Results Fifty per cent of respondents reported fear of their cancer returning. More women than men ((Odds Ratio; (OR) 1.58; 95% confidence interval (CI) 1.46, 1.71)) more younger than older patients (OR 2.53; CI 2.33, 2.74) and slightly more patients from deprived areas (OR 1.14, 1.05, 1.23) reported FCR. Independently of demographics and treatment, compared with those meeting the PA guidelines, those who were doing only ‘some’ (OR 1.22; CI 1.11, 1.35) or ‘no’ PA (OR 1.28; CI 1.15, 1.42) reported higher FCR. Compared with non‐smokers, more current smokers reported fear (OR 1.34, CI 1.10, 1.58) and slightly more ex‐smokers (OR 1.11; CI 1.04, 1.21). Conclusions This cross‐sectional study provided novel data showing that colorectal cancer survivors with poorer health behaviours (those with lower activity levels and those who smoked) were more likely to experience FCR. Future research should replicate findings using detailed measures of fear, objective measures of health behaviours and identify directions of associations. © 2016 The Authors.

An ethnopharmacological and historical analysis of "Dictamnus", a European traditional herbal medicine. JOURNAL OF ETHNOPHARMACOLOGY 2015; 175:390-406.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE AND BACKGROUND "Dictamnus" was a popular name for a group of medicinal herbaceous plant species of the Rutaceae and Lamiaceae, which since the 4th century have been used for gynaecological problems and other illnesses BCE and still appear in numerous ethnobotanical records. AIMS This research has as four overarching aims: Determining the historical evolution of medical preparations labelled "Dictamnus" and the different factors affecting this long-standing herbal tradition. Deciphering and differentiating those medicinal uses of "Dictamnus" which strictly correspond to Dictamnus (Rutaceae), from those of Origanum dictamnus and other Lamiaceae species. Quantitatively assessing the dependence from herbal books, and pharmaceutical tradition, of modern Dictamnus ethnobotanical records. Determining whether differences between Western and Eastern Europe exist with regards to the Dictamnus albus uses in ethnopharmacology and ethnomedicine. METHODS An exhaustive review of herbals, classical pharmacopoeias, ethnobotanical and ethnopharmacological literature was conducted. Systematic analysis of uses reported which were standardized according to International Classification of Diseases - 10 and multivariate analysis using factorial, hierarchical and neighbour joining methods was undertaken. RESULTS AND DISCUSSION The popular concept "Dictamnus" includes Origanum dictamnus L., Ballota pseudodictamnus (L.) Benth. and B. acetabulosa (L.) Benth. (Lamiaceae), as well as Dictamnus albus L. and D. hispanicus Webb ex Willk. (Rutaceae), with 86 different types of uses. Between 1000 and 1700 CE numerous complex preparations with "Dictamnus" were used in the treatment of 35 different pathologies. On biogeographical grounds the widespread D. albus is a far more likely prototypical "Dictamnus" than the Cretan endemic Origanum dictamnus. However both form integral parts of the "Dictamnus" complex. Evidence exists for a sufficiently long and coherent tradition for D. albus and D. hispanicus, use to treat 47 different categories of diseases. CONCLUSIONS This approach is a model for understanding the cultural history of plants and their role as resources for health care. "Dictamnus" shows how transmission of traditional knowledge about materia medica, over 26 centuries, represents remarkable levels of development and innovation. All this lead us to call attention to D. albus and D. hispanicus which are highly promising as potential herbal drug leads. The next steps of research should be to systematically analyse phytochemical, pharmacological and clinical evidence and to develop safety, pharmacology and toxicology profiles of the traditional preparations.

Abstract
BACKGROUND Ultrasound is a standard procedure widely used in the diagnostic investigation of muscle injuries and widely described in the literature. Its advantages include rapid availability, cost effectiveness and the possibility to perform a real-time dynamic examination with the highest possible spatial resolution. In the diagnostic work-up of minor lesions (muscle stiffness, muscle strain), plain ultrasound has so far been inferior to MRI. The case presented by us is an example of the possibilities offered by contrast-enhanced ultrasound (CEUS) in the imaging of muscle injuries compared with plain B-mode image ultrasound and MRI imaging of the affected region. MATERIAL/METHODS This case report is about a high-performance football player who sustained a muscle injury. He underwent an ultrasound examination (S 2000, 9L4 Probe, Siemens, Germany), which was performed simultaneously in the conventional and contrast-enhanced mode at the level of the lesion. An intravenous bolus injection of 4.8 ml of intravascular contrast agent (SonoVue(®), Bracco, Italy) was given via a cubital intravenous line. After that, the distribution of contrast agent was visualised in the early arterial phase. In addition, a plain magnetic resonance imaging scan of both thighs was performed for reference. RESULTS On conventional ultrasound, the lesion was not clearly distinguishable from neighbouring tissue, whereas contrast-enhanced ultrasound demonstrated a well delineated, circumscribed area of impaired perfusion with hypoenhancement compared with the surrounding muscles at the clinical level of the lesion in the arterial wash-in phase (0-30 sec, after intravenous administration). The MRI scan revealed an edema signal with perifascial fluid accumulation in the corresponding site. CONCLUSION The use of intravascular contrast agent enabled the sensitive detection of a minor injury by ultrasound for the first time. An intramuscular edema seen in the MRI scan showed a functional arterial perfusion impairment on ultrasound, which was sensitively detected in the early phase. Further examinations must be performed on muscle injuries of various degrees of severity in order to validate the application of this procedure and to standardise the examination process.

Abstract
BACKGROUND Obesity with its multiple comorbidities has become a global pandemia. We here report on the pathophysiological aspects of obesity-associated urinary bladder dysfunctions. MATERIAL AND METHODS Our results are based on multiple in vitro and in vivo studies including a high fat diet (HFD) rat animal model of which the details are given in the cited publications. RESULTS In cultured human detrusor muscle cells, obesity-related pathophysiological mechanisms were directly induced by the saturated free fatty acid palmitate. In HFD animals, we found serious fibrosis of the bladder wall and downregulation of the muscarinic M3-receptor leading to diminished contractility of the urinary bladder. Bariatric surgical intervention (sleeve gastrectomy) reversed the fibrosis. CONCLUSION Our results support the relevance of obesity for urological bladder dysfunction. The epidemic dimension of obesity with its steadily growing number of cases requires a re-evaluation of this pathological condition in the urological context.

Abstract
BACKGROUND In recent years, children's hospitals have increasingly implemented postoperative pain management protocols to reduce postoperative pain and improve patient satisfaction. The effectiveness and long-term sustainability of such protocols have rarely been studied. Therefore, we conducted a prospective intervention study to assess the impact of regular training and improvement of clinical processes on the quality of postoperative pain management. METHODS We conducted an initial assessment of the status quo of postoperative pain management (Audit 1) followed by repeated training and improvement of clinical processes (analgesic pocket card, parents' brochure, modification of the patient chart, bimonthly advanced trainings sessions) and a follow-up review after 3 years (Audit 2). We used a data entry form, a patient survey, and an anonymous questionnaire for the nursing staff as measurement tools. RESULTS Our analysis included a total of 93 and 85 patients in the initial and final audits. The return rates of the nursing staff questionnaire were 83% (Audit 1) and 77% (Audit 2). The training and process improvements resulted in significant improvement in the administration of analgesics for pain requiring treatment, the control of pain measurement after the administration of analgesics and the use of non-pharmacological pain therapies. The patients reported faster administration of analgesics for acute pain and improved pain relief following the intervention. CONCLUSIONS Repeated training and improvement of clinical processes can significantly improve the long-term quality of postoperative pain management in children with a tolerable amount of effort on the part of health care professionals and institutions.
