Abstract
Abstract
Introduction
Little is known about patients with acute myocardial infarction (AMI) and chronic lung disease (CLD). The aim of our study was to analyze risk factors, treatment, and outcome of AMI patients with CLD over the last 20 years using the nationwide AMIS Plus registry.
Methods
All AMI patients enrolled in the AMIS Plus registry with data on CLD between January 2002 and December 2021 were included. Chronic lung disease was determined according to the definition used in the Charlson Comorbidity Index. Data on baseline characteristics, regular medication, immediate therapy within 24 hours, in-hospital interventions and treatments, in-hospital outcome, complications and discharge medication were analyzed using descriptive statistics and logistic regression.
Results
Among 53,680 AMI patients, 5.8% had a CLD. The CLD group included 26.6% female and 73.4% male patients. Gender distribution was similar in patients with and without CLD. Patients with CLD were significantly older (71.2 vs. 65.8 y; p<0.001), more frequently diagnosed with NSTEMI, had more comorbidities and were less frequently never smokers (17.4% vs. 35.3%; p<0.001) compared to patients without CLD. In addition, CLD patients were less likely to receive aspirin, P2Y12 inhibitors, beta-blockers, ACE inhibitors and statins (all p<0.001), and were also less likely to undergo percutaneous coronary interventions (68.7% vs. 82.5%; p<0.001). Median length of stay was 2 days longer for CLD patients. Patients with CLD had more major adverse cardiac and cerebrovascular events in-hospital (10.3% vs. 5.9%; p<0.001) and higher crude in-hospital mortality (8.3% vs. 4.7%; p<0.001). However, multivariable regression analysis showed that CLD was not an independent predictor for in-hospital mortality (OR 1.19 (95% CI 0.98–1.45), p=0.081).
Conclusion
Patients with CLD were less likely to receive evidence-based medicine and had a worse in-hospital outcome compared to those without CLD. However, after adjustment, CLD was not an independent predictor of in-hospital mortality.

Abstract
The assessment of contaminants of emerging concern, alone and in mixtures, and their effects on marine biota requires attention. 5-Fluorouracil is a cytostatic category 3 anti-cancer medication (IARC) that is used to treat a variety of cancers, including colon, pancreatic, and breast cancer. In the presence of other pollutants, this pharmaceutical can interact and form mixtures of contaminants, such as adhering to plastics and interaction with metal nanoparticles. This study aimed to comprehend the effects of 5-Fluorouracil (5FU; 10 ng/L) and a mixture of emerging contaminants (Mix): silver nanoparticles (nAg; 20 nm; 10 μg/L), polystyrene nanoparticles (nPS; 50 nm; 10 μg/L) and 5FU (10 ng/L), in an in vivo (21 days) exposure of the mussel Mytilus galloprovincialis. A multibiomarker approach namely genotoxicity, the antioxidant defence system (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidases (GPx), glutathione - S - transferases (GST) activities), and oxidative damage (LPO) was used to assess the effects in gills and digestive gland of mussels. Both treatments cause genotoxicity in mussel's haemolymph, and antagonism between contaminants was observed in the Mix. Genotoxicity observed confirms 5FU's mode of action (MoA) by DNA damage. The antioxidant defence system of mussels exposed to 5FU kicked in and counter balanced ROS generated during the exposure, though the same was not seen in Mix-exposed mussels. Mussels were able to withstand the effects of the single compound but not the effects of the Mix. For oxidative stress and damage, the interactions of the components of the mixture have a synergistic effect.

Abstract
BACKGROUND The neurocognitive mechanisms underlying autism spectrum disorder (ASD) remain unclear. Progress has been largely hampered by small sample sizes, variable age ranges and resulting inconsistent findings. There is a pressing need for large definitive studies to delineate the nature and extent of key case/control differences to direct research towards fruitful areas for future investigation. Here we focus on perception of biological motion, a promising index of social brain function which may be altered in ASD. In a large sample ranging from childhood to adulthood, we assess whether biological motion preference differs in ASD compared to neurotypical participants (NT), how differences are modulated by age and sex and whether they are associated with dimensional variation in concurrent or later symptomatology. METHODS Eye-tracking data were collected from 486 6-to-30-year-old autistic (N = 282) and non-autistic control (N = 204) participants whilst they viewed 28 trials pairing biological (BM) and control (non-biological, CTRL) motion. Preference for the biological motion stimulus was calculated as (1) proportion looking time difference (BM-CTRL) and (2) peak look duration difference (BM-CTRL). RESULTS The ASD group showed a present but weaker preference for biological motion than the NT group. The nature of the control stimulus modulated preference for biological motion in both groups. Biological motion preference did not vary with age, gender, or concurrent or prospective social communicative skill within the ASD group, although a lack of clear preference for either stimulus was associated with higher social-communicative symptoms at baseline. LIMITATIONS The paired visual preference we used may underestimate preference for a stimulus in younger and lower IQ individuals. Our ASD group had a lower average IQ by approximately seven points. 18% of our sample was not analysed for various technical and behavioural reasons. CONCLUSIONS Biological motion preference elicits small-to-medium-sized case-control effects, but individual differences do not strongly relate to core social autism associated symptomatology. We interpret this as an autistic difference (as opposed to a deficit) likely manifest in social brain regions. The extent to which this is an innate difference present from birth and central to the autistic phenotype, or the consequence of a life lived with ASD, is unclear.

Abstract
BACKGROUND Gastrointestinal infections are caused by a broad spectrum of pathogens. Conventional diagnostic procedures are resource and time consuming due to single pathogen testing, often in different laboratories. METHOD We analyzed 312 consecutive stool samples from pediatric patients (n = 127) with gastroenteritis or from adult travelers returning from the tropics with suspected parasite infestation (n = 185) using commercial multiplex nucleic acid amplification testing (NAT) (xTAG gastrointestinal pathogen panel, Luminex) covering 15 diarrhea-causing pathogens. The results of the positive samples and a representative number of negative samples were compared to standard methods, including NAT, direct antigen detection (DAD), bacterial culture and microscopy. RESULTS Of the 185 samples from adult travelers, 21 (11 %) were multiplexNAT-positive, with enterotoxigenic Escherichia coli (4 %) being the predominant pathogen. Microscopic examination revealed Blastocystis hominis in 23 % not covered by the panel. MultiplexNAT scored positive in 66 pediatric samples (52 %), with rotavirus (27 %) being the most prevalent. All adenovirus-, rotavirus-, Clostridium difficile- and Cryptosporidium-positive samples were confirmed in external laboratories, but only 40 % of norovirus- and 29 % of Giardia-positive samples. Analysis of frozen specimens by bacterial culture showed the highest discrepancies with the multiplexNAT. CONCLUSION Our study demonstrates broad detection of relevant gastroenteritis pathogens by multiplexNAT with a short turnaround time. This is important for diagnosis, infection control and empiric management of gastroenteritis patients, but may be selectively complemented by bacterial culture and resistance testing.

Abstract
BACKGROUND AND PURPOSE Strokes caused by lesions to certain brain areas are associated with poor outcome, which is important both prognostically and to understand the neural basis for recovery. However, lesion anatomy associations with outcome may occur because of effects on baseline severity rather than because of effects on recovery per se. Here, all common stroke locations were surveyed to determine the strongest lesion anatomy associations separately for baseline functional severity and proportional recovery. Since most recovery occurs early, the focus here is on functional changes over the first week. METHOD Global functional scores (National Institutes of Health Stroke Scale) at baseline and proportional recovery over 1 week were derived from the records of 550 ischaemic stroke patients and related to magnetic resonance imaging lesion location using voxel-lesion mapping. The effects of lesions extending over more than one location were also considered. Cross-validation estimated the percentage of recovery rate variance (r(2) ) accountable by lesion location information. RESULTS High baseline severity was associated with lesions to the left capsule, striatum and thalamocortical white matter, whereas high recovery rate was associated with lesions to more superficial left fronto-temporal areas. Low recovery rates were associated with lesions to bilateral parietal, right insula, medial frontal, capsule and brainstem. Inclusion of these regions into a multivariate model of proportional recovery rate increased r(2) from 8% to 45%. CONCLUSION The strongest stroke lesion location associations with 1-week recovery were identified, and it was shown that anatomical information accounts for a sizeable proportion of early recovery variability.

Abstract
BACKGROUND AND PURPOSE α(1) -Adrenoceptor-induced contraction of prostate smooth muscle is mediated by calcium- and Rho kinase-dependent mechanisms. In addition, other mechanisms, such as activation of c-jun N-terminal kinase (JNK) may be involved. Here, we investigated whether JNK participates in α(1)-adrenoceptor-induced contraction of human prostate smooth muscle. EXPERIMENTAL APPROACH Prostate tissue was obtained from patients undergoing radical prostatectomy. Effects of the JNK inhibitors SP600125 (50 µM) and BI-78D3 (30 µM) on contractions induced by phenylephrine, noradrenaline and electric field stimulation (EFS) were studied in myographic measurements. JNK activation by noradrenaline (30 µM) and phenylephrine (10 µM), and the effects of JNK inhibitors of c-Jun phosphorylation were assessed by Western blot analyses with phospho-specific antibodies. Expression of JNK was studied by immunohistochemistry and fluorescence double staining. KEY RESULTS The JNK inhibitors SP600125 and BI-78D3 reduced phenylephrine- and noradrenaline-induced contractions of human prostate strips. In addition, SP600125 reduced EFS-induced contraction of prostate strips. Stimulation of prostate tissue with noradrenaline or phenylephrine in vitro resulted in activation of JNK. Incubation of prostate tissue with SP600125 or BI-78D3 reduced the phosphorylation state of c-Jun. Immunohistochemical staining demonstrated the expression of JNK in smooth muscle cells of human prostate tissue. Fluorescence staining showed that α(1A)-adrenoceptors and JNK are expressed in the same cells. CONCLUSIONS AND IMPLICATIONS Activation of JNK is involved in α(1)-adrenoceptor-induced prostate smooth muscle contraction. Models of α(1)-adrenoceptor-mediated prostate smooth muscle contraction should include this JNK-dependent mechanism.

Abstract
We performed a prospective multi-centre study using functional magnetic resonance imaging (fMRI) to better characterize the relationships between clinical expression and brain function in patients with multiple sclerosis (MS) at eight European sites (56 MS patients and 60 age-matched, healthy controls). Patients showed greater task-related activation bilaterally in brain regions including the pre- and post-central, inferior and superior frontal, cingulate and superior temporal gyri and insula (P < 0.05, all statistics corrected for multiple comparisons). Both patients and healthy controls showed greater brain activation with increasing age in the ipsilateral pre-central and inferior frontal gyri (P < 0.05). Patients, but not controls, showed greater brain activation in the anterior cingulate gyrus and the bilateral ventral striatum (P < 0.05) with less hand dexterity. An interaction between functional activation changes in MS and age was found. This large fMRI study over a broadly selected MS patient population confirms that movement for patients demands significantly greater cognitive 'resource allocation' and suggests age-related differences in brain responses to the disease. These observations add to evidence that brain functional responses (including potentially adaptive brain plasticity) contribute to modulation of clinical expression of MS pathology and demonstrate the feasibility of a multi-site functional MRI study of MS.

Abstract
BACKGROUND Budesonide is effective as initial therapy of mild to moderate Crohn's disease in adults. Superior tolerability to conventional corticosteroids might be attributed to extensive first-pass metabolism of budesonide by cytochrome P450 3A. AIM To evaluate biotransformation and pharmacodynamic action of budesonide in children. METHODS Drug disposition and effects on endogenous cortisol were evaluated in 12 children with Crohn's disease (5-15 years) after first intake of 3 mg budesonide (single dose), and again after 1 week of thrice daily dosing (steady-state). The parent drug and cytochrome P450 3A-dependent metabolites were analysed in blood and urine. RESULTS Pharmacokinetic parameters of budesonide following single-dose administration (e.g. AUC(0-infinity) 7.7+/-5.1 h ng/mL, C(max) 1.8+/-1.2 ng/mL) did not change upon multiple dosing. Overall systemic elimination of budesonide reflected by clearance and half-life was not different between children and adults. After 1 week of treatment reversible adrenal suppression was observed - most pronounced in children aged below 12 years. CONCLUSIONS Disposition of oral budesonide appears to be similar between children and adults, but the doctor has to be aware of an increased risk for adrenal suppression in paediatric patients.

Abstract
The goal was a better understanding of the correlation between body mass and plantar peak pressure in patients with diabetic neuropathy. A further aim was to obtain insight into the practicability of simulated weight increase and weight release and to delineate more clearly the indications for reducing body weight in order to lower the risk of ulcerations. Simulated change of body weight: (1) +20 kg by a waistcoat and (2)-20 kg by a movable overhead suspension. While normal forces and thus mean normal pressures depend directly on body mass, this does not necessarily apply to peak normal pressures. As shown in a transversal study by Cavanagh with pressure measurements in the bare foot, there is only a poor correlation between body mass and peak pressure. Therefore, peak pressure in heavy persons cannot be expected to be higher than in lighter weight persons. However, from these results it cannot be concluded that peak pressure is likely to remain unchanged irrespective of a change in body weight in a specific subject. Ten subjects were investigated: five controls and five patients suffering from diabetes without neuropathy or preceding ulcerations. All subjects wore the same kind of ready made shoes with ready made standard fitting insoles of cork. Each subject was measured in three modes of weight simulation: normal weight,20 kg weight increase (waistcoat with weight pieces), and 20 kg weight release. Weight release was effected by a modified rescue harness attached to an overhead suspension rail with 6m free walking distance. Individual alignment of the waistcoat and the suspension was checked by a force platform. In-shoe pressure measurement was done with the PEDAR in-shoe system (by Novel, Munich,Germany). For data analysis with the PEDAR standard software only peak pressures were considered. The foot was divided into six regions, particularly metatarsal region and heel. No significant difference between diabetics and controls was found. In the regions at highest risk (metatarsals and heel),peak pressure increased and decreased with weight. In the combined group (n=10), a simulated weight loss of 20 kg decreased metatarsal peak pressure by 5.4+/-1.9 N/cm(2), a 20 kg weight gain increased it by 7.4+/-5.1 N/cm(2). Therefore, without a significant deviation from linearity, peak pressure was found to be a linear function of weight. The results of this study show that weight increase or weight loss in the individual patient has an effect on the plantar peak pressure. The effect is significant in the metatarsal and heel regions. The linearity allows for a simple method of predicting the effect of weight loss by inverting the effect of simulated weight gain.

Abstract
Functional magnetic resonance imaging (fMRI), which allows non-invasive mapping of human cognitive functions, has become an important tool for understanding language function. An understanding of component processes and sources of noise in the images is contributing to increased confidence in the reproductability of studies. This allows clinical applications, e.g., for pre-surgical lateralisation of language functions in patients with temporal lobe epilepsy. fMRI is a sensitive method for mapping regions involved in language functions. We recently have applied it to study the effect of word surface form on reading with a comparison of responses to Chinese characters or alphabetical Pinyin. Interpretation of fMRI activations must be made with caution; fMRI suggests task-associated activation, but does not independently confirm that such activity is necessary. However, complementary studies can be performed using transcranial magnetic stimulation (TMS), which can be used to interfere with brain activity in a specific region transiently for characterisation of the behavioural effects. We describe how TMS combined with fMRI has confirmed a role for the left inferior frontal cortex in semantic processing.

Abstract
OBJECTIVES According to recent studies, 1.3 to 4.8% of the population of Western industrialized nations suffer from fibromyalgia, with 80 to 90% of the affected persons being women. This preponderance of women, mostly in their reproductive years, suggests an association between fibromyalgia and sex hormones. METHODS Within the framework of a population-based cross-sectional study of 3174 female residents of Bad Säckingen aged 35 to 74 years a stratified random sample of 653 women was clinically examined and surveyed. Thirty-six of these women fulfilled the ACR criteria of fibromyalgia. Forty-four women suffered from chronic widespread pain without having fibromyalgia (chronic pain group); 408 had no chronic pain (controls). RESULTS Compared to the control group, subjects with fibromyalgia have a 3.6-fold risk, while compared to the chronic pain group, there is a 3.9-fold risk of having a lower social level. Subjects with fibromyalgia drink less alcohol than subjects from the chronic pain group and the control group. After adjusting for age, multivariate analyses demonstrated that, in comparison to controls, subjects with fibromyalgia have a significantly later menarche (OR=2.2 for >14 years) and had never been pregnant (OR=0.3). The comparison of the chronic pain group and controls did not demonstrate these associations. CONCLUSIONS The associations with a low social level, low alcohol intake, late menarche and rare pregnancies are specific for subjects with fibromyalgia. These factors distinguish subjects with fibromyalgia from subjects with other chronic pain conditions as well as from subjects with no chronic pain. The same hormonal factors responsible for a delayed menarche and a reduced fertility may be relevant in the development of fibromyalgia.

Abstract
High background fluorescence and unspecific staining hampered the epifluorescence enumeration of bacteria in 45% of the tested soil and sediment samples with 4',6-diamidino-2-phenylindole (DAPI) and polycarbonate membrane filters. These problems of the determination of total cell counts can be circumvented by using green fluorescent high-affinity nucleic acid dyes and aluminum oxide membrane filters. Due to the bright staining of cells, we recommend SYBR Green II as dye.

Abstract
We have previously described a monoclonal antibody (mAb), 10C3, directed against the gene-3 protein (g3p) of filamentous phage M13, which was produced to study g3p fusion protein expression in Escherichia coli and its incorporation in the phage capsid [Tesar, M., Beckmann, C., Röttgen, P., Haase, B., Faude, U., Timmis, K., 1995. Monoclonal antibody against pIII of filamentous phage: an immunological tool to study pIII fusion protein expression in phage display systems. Immunology 1, 53-54]. In this study we report mapping of the antigenic epitope of the mAb 10C3, by means of short overlapping peptide-sequences [Frank, R., Overwin, H., 1996. Spot synthesis. In: Morris, G.E. (Ed.), Methods in Molecular Biology, Vol. 66: Epitope Mapping Protocols. Humana Press, Totowa, NJ, pp. 149-169.] comprising the C-terminal half of the g3-protein. A minimal recognizable peptide was found which is represented in the 11 amino acid sequence from positions 292 to 302 of g3p [Wezenbeek van, P.M.G.P., Hulsebos, T.J.M., Schoenmakers, J.G.G., 1980. Nucleotide sequence of the filamentous bacteriophage M13 DNA genome: comparison with phage fd. Gene 11, 129-148]. In order to use the antibody also for detection and purification of recombinant proteins, such as single chain antibodies, the epitope was introduced as a tag sequence into the phagemid pHEN1 [Hoogenboom, H.R., Griffith, A.D., Johnson, K., Chiswell, D.J., Hudson, P., Winter, G., 1991. Multi-subunit proteins on the surface of the filamentous phage: methodologies for displaying antibody (Fab) heavy and light chains. Nucleic Acid Res. 19, 4133-4137; Nissim, A., Hoogenboom, H.R., Tomlinson, I.M., Flynn, G., Midgley, C., Lane, D., Winter, G., 1994. Antibody fragments from a single pot phage display library as immunochemical reagents. EMBO J. 13 (3) 692-698]. Purified single chain antibodies containing this tag were detectable down to a concentration of 2 ng ml(-1) under non-denaturing conditions (ELISA) or 4 ng per lane on immunoblots. The high sensitivity of the antibody for the peptide tag was reflected in the antibody affinity constant K(D) of 6.80 x 10(-10) M, which was determined by real time biomolecular interaction analysis (BIA) based on surface plasmon resonance (SPR) [Karlsson, R., Fält, A., 1997. Experimental design for kinetic analysis of protein-protein interactions with surface plasmon resonance biosensors. J. Immunol. Methods 200, 121-133]. Finally, recombinant proteins in E. coli periplasmic extracts could be purified in a single step by affinity purification using immobilized mAb 10C3. These studies demonstrated that the new peptide-tag and its corresponding mAb represents a versatile tool for the detection of recombinant proteins selected by phage display technology.

Abstract
UNLABELLED A monoclonal antibody directed against the gene 3 product (pIII) of filamentous phage M13 was produced to study pIII-fusion protein expression in E. coli and its incorporation in the phage capsid. The protein was gel-purified from E. coli expression cultures harboring the genetic information of pIII under the control of an inducible lac promoter. To study pIII-fusion protein expression, phage display systems were applied in which either the whole pIII or the C-terminal half was used (McCafferty et al. (1990) Nature (London) 348, 552-554; Szardenings and Collins (1990) Gene 94, 1-7; Barbas and Lerner (1991) In: METHODS Companion to METHODS in Enzymology, Combinatorial Immunoglobulin Libraries on the Surface of Phage (Phabs): Rapid Selection of Antigen-Specific Fabs, Vol. 2, Academic Press, Orlando, pp. 119-124). In all cases, the monoclonal antibody was able to detect the native and the recombinant protein in E. coli and on the phage tip using non-denaturing (ELISA) and denaturing (SDS-PAGE, immunoblot analysis) conditions. All selected pIII-specific monoclonal antibodies were found to be directed against epitopes within amino acids 198 to 406 of pIII, which is necessary for capsid incorporation and therefore included in all pIII-mediated phage display designs.

Abstract
The horizontal and spatial distribution of artificial and natural radionuclides in soils, and the vertical migration velocity of 0.8-2.0 cm per annum for caesium were examined in order to determine whether caesium is still in the root zone of major plants and, therefore, part of the food-chain. The vertical distribution patterns of caesium are dependent on the different physico-chemical soil properties. The soil samples were analysed with a pure Ge detector. In south-eastern Lower Saxony, the maximum gamma-activity for 137Cs of 33.3 kBq m-2 was found in a depth range of 0-20 cm (January 1, 1989). This was correlated with areas that had received heavy rainfall on May 4, 1986. On January 1, 1989 approximately 60% of the Chernobyl caesium was still in the top 0-2 cm of the topsoil.

Abstract
Intrauterine retention of fetal bone is a rare complication of abortion that can cause secondary infertility by an unknown mechanism. We report such a case in which menstrual fluid prostanoids were measured to elucidate the possible pathophysiology. The pattern of prostanoid increases was similar to that seen in intrauterine device users.

Abstract
9 cases of "thorotrast kidney" after retrograde pyelography with reflux are presented. In 6 patients carcinoma of the renal pelvis developed 47--31 years after thorotrast pyelography. Because of this high rate of carcinoma induction, thorotrast kidney must be classified as a precancerous condition with high-rate tumor manifestation. Thorotrast kidney is diagnosed on X-ray by very opaque linear densities following the calices and pyelon. Early ureteronephrectomy is the treatment of choice in unilateral thorotrast kidneys. If uretero-nephrectomy is not possible, the patient should be followed up regularly with urinary cytologic examinations for early detection of malignancy.

Abstract
The phenolsulphthalein 60/60 plasma test (PSP 60/60) was evaluated in 30 control subjects (mean value 51 micrograms/100 ml +/- 49 micrograms/100 ml) and 60 patients with chronic renal disease with varying degrees of renal insufficiency. PSP 60/60 proved to be superior to determination of serum creatinine and urea nitrogen. PSP 60/60 correlated well with endogenous creatinine clearance and 131I-iodohippurate clearance in over 80% of cases. Of various exogenous and endogenous factors interfering with the test, drugs influencing renal excretory mechanisms are most important. Due to its technical simplicity, PSP 60/60 is a useful screening test for evaluation of renal function, especially as an office procedure.

Abstract
The new semisynthetic epipodophyllotoxin VP 16-213 has been tested for antitumor activity and toxicity in a non-randomized phase II trial. The study included 33 patients with solid tumors and acute leukemias. The drug was given in 5-day courses every 3 weeks, parenterally for the first 2 courses and thereafter orally. Subjectively VP 16-213 was well tolerated in both i.v. and oral administration, but almost universally induced leukothrombopenia and hair loss. The best results were achieved in 12 patients with oat cell carcinoma of the lung (4 good and 4 less good responses). Remissions of lesser quality were also observed in anaplastic lung cancer, ovarian carcinoma and acute myelomonocytic leukemia. VP 16-213 possesses proven, clinically valuable cytostatic activity against various human neoplasms. Complementary studies to establish its optimum dosage and administration, and its place in combination chemotherapy, are in progress.
