Abstract
In human-human and human-robot interaction, the counterpart influences the human's affective state. Contrary to humans, robots inherently cannot respond empathically, meaning non-beneficial affective reactions cannot be mitigated. Thus, to create a responsible and empathetic human-robot interaction (HRI), involving anthropomorphic service robots, the effect of robot behavior on human affect in HRI must be understood. To contribute to this understanding, we provide the new comprehensive data set AFFECT-HRI, including, for the first time, physiological data labeled with human affect (i.e., emotions and mood) gathered from a conducted HRI study. Within the study, 146 participants interacted with an anthropomorphic service robot in a realistic and complex retail scenario. The participants' questionnaire ratings regarding affect, demographics, and socio-technical ratings are provided in the data set. Five different conditions (i.e., neutral, transparency, liability, moral, and immoral) were considered during the study, eliciting different affective reactions and allowing interdisciplinary investigations (e.g., computer science, law, and psychology). Each condition includes three scenes: a consultation regarding products, a request for sensitive personal information, and a handover.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks on cruise ships have rarely been investigated. In early 2022, we were informed about a SARS-CoV-2 outbreak on a cruise ship calling Port of Hamburg after 10 infections among crew members were detected. We conducted an outbreak investigation in collaboration between ship owners, the ship physician and Hamburg's Institute for Hygiene and Environment, to identify risk factors and to achieve containment. The aim was to identify risk factors for SARS-CoV-2 infection and SARS-CoV-2 variants in a cohort of 165 crew members. MATERIALS AND METHODS For this purpose, we collected data on age, sex, nationality, boarding-time, cabin use (single/shared), work place, and vaccination status of the study participants. Cases were defined as individuals who tested SARS-CoV-2 positive at least once in daily screenings during the outbreak period (10 days) by polymerase chain reaction or antigen test. We investigated risk factors for infection by descriptive, univariable and multivariable analysis. We performed whole genome sequencing to identify SARS-CoV-2 variants. RESULTS We verified 103 SARS-CoV-2 positive cases (attack rate [AR] 62.4%); 39/41 sequenced samples were BA.2.3 Omicron subtype, one BA.1 and one BA.1.1. Among boostered crew members, AR was 38% vs. 65% among those vaccinated once or twice. Among those who stayed < 30 days on board, AR was 31% vs. 72% among those staying on board longer. Among Europeans, the AR was 53% vs. 71% in non- -Europeans. Adjusting for age and sex, cases were more likely to have received no booster vaccine (odds ratio [OR]: 2.66, 95% confidence interval [CI]: 0.99-7.13), to have spent more time on board (≥ 30 days, OR: 6.36, 95% CI: 2.81-14.40 vs. < 30 days) and to have a non-European nationality (OR: 2.14, 95% CI: 1.08-4.27). The outbreak stopped shortly after offboard isolation of cases. CONCLUSIONS This investigation confirms the importance of a booster vaccine against COVID-19. Longer stays onboard could facilitate social mixing. Further studies could investigate the impact of social, cultural/ behavioural patterns and public health access on the infection risk. Physical distancing together with screening and isolation can contain SARS-CoV-2 outbreaks on cruise ships.

Abstract
The transition to a sustainable bio-based circular economy requires cutting edge technologies that ensure economic growth with environmentally responsible action. This transition will only be feasible when the opportunities of digitalization are also exploited. Digital methods and big data handling have already found their way into life sciences and generally offer huge potential in various research areas. While computational analyses of microbial metagenome data have become state of the art, the true potential of bioinformatics remains mostly untapped so far. In this article we present challenges and opportunities of digitalization including multi-omics approaches in discovering and exploiting the microbial diversity of the planet with the aim to identify robust biocatalysts for application in sustainable bioprocesses as part of the transition from a fossil-based to a bio-based circular economy. This will contribute to solving global challenges, including utilization of natural resources, food supply, health, energy and the environment.

Abstract
DGGE analysis combined with a metagenomic approach was used to get insights into heterotrophic anoxic enrichment cultures of four hot springs of Vale das Furnas, Portugal, using the recalcitrant substrate spent coffee ground (SCG). Parallel enrichment cultures were performed using the major components of spent coffee ground, namely arabinogalactan, galactomannan, cellulose, and proteins. DGGE revealed that heterotrophic thermophilic bacteria are highly abundant in the hydrothermal springs and significant differences in community composition depending on the substrate were observed. DNA, isolated from enrichment cultures of different locations that were grown on the same substrate were pooled, and the respective metagenomes were analyzed. Results indicated that cultures grown on recalcitrant substrate SCG consists of a totally different thermophilic community, dominated by Dictyoglomus. Enrichments with galactomannan and arabinogalactan were dominated by Thermodesulfovibrio, while cultures with casein and cellulose were dominated by Thermus. This study indicates the high potential of thermophilic bacteria degrading recalcitrant substrate such as SCG and furthermore how the accessibility to complex polymers shapes the bacterial community.

Abstract
From a biogas reactor metagenome an ORF (bp_cel9A) encoding a bacterial theme C glycoside hydrolase family 9 (GH9) enzyme was recombinantly produced in E. coli BL21 pQE-80L. BP_Cel9A exhibited ≤ 55% identity to annotated sequences. Subsequently, the enzyme was purified to homogeneity by affinity chromatography. The endo-beta-glucanase BP_Cel9A hydrolyzed the beta-1,3-1,4-linked barley beta-glucan with 24 U/mg at 30 °C and pH 6.0. More than 62% of activity was measured between 10 and 40 °C. Lichenan and xyloglucan were hydrolyzed with 67% and 40% of activity, respectively. The activity towards different substrates varied with different temperatures. However, the enzyme activity on CMC was extremely low (> 1%). In contrast to BP_Cel9A, most GH9 glucanases act preferably on crystalline or soluble cellulose with only side activities towards related substrates. The addition of calcium or magnesium enhanced the activity of BP_Cel9A, especially at higher temperatures. EDTA inhibited the enzyme, whereas EGTA had no effect, suggesting that Mg2+ may adopt the function of Ca2+. BP_Cel9A exhibited a unique substrate spectrum when compared to other GH9 enzymes with great potential for mixed-linked glucan or xyloglucan degrading processes at moderate temperatures.

Abstract
BACKGROUND Obesity has been shown to trigger adaptive increases in pancreas parenchymal and fat volume. Consecutively, pancreatic steatosis may lead to beta-cell dysfunction. However, it is not known whether the pancreatic tissue components decrease with weight loss and pancreatic steatosis is reversible following Roux-en-Y gastric bypass (RYGB). Therefore, the objective of the study was to investigate the effects of RYGB-induced weight loss on pancreatic volume and glucose homeostasis. METHODS Eleven patients were recruited in the Obesity Centre of the University Medical Centre Hamburg-Eppendorf. Before and 6 months after RYGB, total GLP-1 levels were measured during oral glucose tolerance test. To assess changes in visceral adipose tissue and pancreatic volume, MRI was performed. Measures of glucose homeostasis and insulin indices were assessed. Fractional beta-cell area was estimated by correlation with the C-peptide-to-glucose ratio; beta-cell mass was calculated by the product of beta-cell area and pancreas parenchymal weight. RESULTS Pancreas volume decreased from 83.8 (75.7-92.0) to 70.5 (58.8-82.3) cm3 (mean [95% CI], P = .001). The decrease in total volume was associated with a significant decrease in fat volume. Fasting insulin and C-peptide were lower post RYGB. HOMA-IR levels decreased, whereas insulin sensitivity increased (P = .03). This was consistent with a reduction in the estimated beta-cell area and mass. CONCLUSIONS Following RYGB, pancreatic volume and steatosis adaptively decreased to "normal" levels with accompanying improvement in glucose homeostasis. Moreover, obesity-driven beta-cell expansion seems to be reversible; however, future studies must define a method to more accurately estimate functional beta-cell mass to increase our understanding of glucose homeostasis after RYGB.

Abstract
OBJECTIVES To develop a routinely applicable severity index for the management of acute appendicitis in adults using combined clinical and radiological parameters and retroperitoneal space planes (RSP). METHODS Two hundred consecutive patients with histologically proven acute appendicitis and available presurgical CT scans were analysed retrospectively. Two radiologists assessed all CT scans for morphologic sings of appendicitis and six RSP. Clinical parameters were age, body temperature, C-reactive protein (CRP), white blood cell count, and duration of symptoms. Radiological parameters were appendix diameter and wall thickness, periappendiceal fat stranding and fluid, intraluminal and extraluminal air, thinning of appendiceal wall, caecal wall thickening, appendicolith and abscess formation. RESULTS One hundred and three patients (51%) had histologically proven complicated appendicitis. Based on three clinical (age ≥52 years, body temperature ≥37.5°C, duration of symptoms ≥48 h) and four computed tomography (CT) findings (appendix diameter ≥14 mm, presence of periappendiceal fluid, extraluminal air, perityphlitic abscess), the APSI was developed using regression coefficients of multivariate logistic regression analyses with a maximum of 10 points. A score of ≥4 points predicted complicated appendicitis with a positive predictive value of 92% and a negative predictive value of 83%. Substantial to excellent interobserver agreement was found for the four radiological parameters of the APSI [intraclass correlation coefficient (ICC), 0.78-0.83]. The RSP evaluation presented no added value for the diagnosis of complicated appendicitis. CONCLUSIONS Using APSI, an accurate and simple prediction of complicated appendicitis in adults was possible. The RSP count was not useful for the diagnosis of complicated appendicitis. KEY POINTS • Appendicitis severity score provides an accurate and simple prediction of complicated appendicitis • Appendicitis severity score ≥4 accurately predicted complicated appendicitis (PPV 92%;NPV 83%) • Evaluation of retroperitoneal space planes was not useful in diagnosing complicated appendicitis.

Abstract
BACKGROUND/PURPOSE Endoscopic ultrasound-guided drainage (EUS-GD) of postoperative abdominal fluid collections (POFC) following pancreatic surgery is used as an alternative or complement to percutaneous drainage (PD) procedure. The present single-center retrospective study evaluates its efficacy and safety. METHOD We included consecutive cases with POFC treated by EUS-GD between September 2009 and November 2014 in our department. Technical success, long-term clinical success, recurrence rate and need for surgery were analyzed. RESULTS 24 procedures in 20 patients (95 % after pancreatic resection) were assessed. Indications for surgery included tumors/lesions located in the pancreas (15/20), chronic pancreatitis (3/20) and duodenal adenoma not completely resectable endoscopically (2/20). EUS-GD was performed within a median of 30 days (IQR: 8.25) for a median fluid collection size of 72.5 mm (IQR: 46.25), requiring a mean of 1.2 sessions with placement of a mean of 2.1 plastic stents (7 Fr/10 Fr) per patient for a mean of 89 days (IQR: 127). Microbiology of aspirated fluid revealed positive cultures in 13 patients, mostly polymicrobial, isolated positive for fungal and 3 multidrug-resistant gram negative (MRGN) in 4 cases. An additional transpapillary drainage was inserted in 1/20 patients. 4/20 patients received PD, mostly before EUS-GD. Technical and clinical success was achieved in 20/20 (100 %) and 18/20 (90 %) patients, respectively, while 2 patients required re-operation. During follow-up (median 630 days after stent removal, range: 45 - 2160), recurrence occurred in 1/18 (5.5 %) patient that was referred for surgery. No death or severe adverse events were noted. CONCLUSION EUS-GD is an effective, minimally invasive and safe method for therapy of POFC after pancreatic surgery offering long-term remission in about 95 % of cases.

Abstract
The lamellar ordering of bicontinuous microemulsions adjacent to a planar hydrophilic wall is investigated experimentally by grazing-incidence small-angle neutron scattering and theoretically by computer simulations. It is shown that precise depth information in neutron scattering can be obtained by tuning the scattering length density of the overall microemulsion. Neutron reflectometry completes the characterization. The nucleation of a lamellar phase at the wall is observed, and a perforated lamellar transition region is identified at the lamellar-microemulsion interface. The thickness of the lamellar region is about 400 Å, which corresponds to two bilayers.

Abstract
The addition of a macromolecular crowding agent to a dilute solution of polymer exerts a compressive force that tends to reduce the size of the chain. We study here the effect of changing the size ratio between the random coil and the crowding agent. The compression occurs at lower crowding agent concentration, Φ when polymer molecular weight increases. The Flory exponent ν(Φ) decreases from ν(0)≃0.48 in water down to 0.3 with macromolecular crowding. The effective polymer-polymer interactions change from repulsive to strongly attractive inducing aggregation of the chains. This effect changes drastically for larger polymer sizes, being much more pronounced at high molecular weights.

Abstract
Glycemic and body weight control are two outstanding goals in the treatment of patients with type 2 diabetes that often are not appropriately achieved. This observational study evaluates whether treatment by quality controlled diabetes centers generates an improvement in this regard and focuses on associations with different therapies. Data of 9.294 type 2 diabetic patients (mean age 66.9±11.6 years, mean diabetes duration 12.4±9.2 years) from 103 German diabetes centers were assessed by a standardized, prospective, computer-based diabetes care and outcome documentation system (DPV-Wiss-database). Therapeutic concepts included lifestyle intervention (n=1.813), oral antidiabetics (OAD, n=1.536), insulin (n=4.504) and insulin plus OAD (n=1.441). HbA1c and body weight were compared before and after a stable therapeutical period of 1.07±0.3 years. Change in HbA1c (%): all patients 7.4±1.6-7.0±1.3, lifestyle intervention 7.5±1.9-6.9±1.5, OAD 6.7±1.1-6.5±1.0, insulin 7.6±1.6-7.2±1.4, insulin plus OAD 7.5±1.5-7.2±1.3; each p≤0.05. Change in body weight (kg): all patients +0.08±0.07, n. s.; lifestyle intervention -0.28±0.20, OAD -0.56±0.13, each p<0.05 [metfomin -0.77±0.21, sulfonylurea drugs -0.75±0.34, each p<0.05; glitazones +0.62±0.70, α-glucosidase inhibitors -0.22±0.76, each n. s.], insulin +0.27±0.10, insulin plus OAD +0.63±0.14, each n. s. In summary, lifestyle, metformin or sulfonylurea drug treatment resulted in HbA1c-values below 7.0% plus a significant weight reduction. Insulin treatment-associated concepts resulted in HbA1c-values slightly above 7.0% without body weight alterations. These "real life" data underline that a specialised and quality controlled diabetes care is able to achieve significant treatment results even in patients with disease progression and a high proportion of insulin therapies.

Abstract
Background: Rehabilitation programs are comprehensive interventions which effectively improve the health status and reduce costs in chronic respiratory illnesses. Because patients with cystic fibrosis have been discouraged to participate for concerns of microbial cross infection, the efficacy of systematic rehabilitation is unknown for this group. Methods: We retrospectively studied 142 cystic fibrosis patients aged 2-46 years who participated in rehabilitation programs taking place in Germany/Switzerland and in Israel, focusing on changes in lung function and weight. Results: During 172 stays in 97 patients in Israel and 68 stays in 45 patients rehabilitating in Germany/Switzerland, overall lung function and weight improved. Outcome did not differ between Israel and German/Swiss sites. Interestingly, lung function improved during the initial phase of the stay, whereas weight gain was sustained throughout. The study uncovered gaps in reporting sufficient individual outcome information back to the admitting centre. Conclusions: Rehabilitation programs specified for cystic fibrosis patients need to be assessed prospectively to optimize treatment of this life limiting condition.

Abstract
e15640 Background: The objective of this study was to investigate whether limited resection of the oesophagogastric junction can be successfully used in the treatment of the patients with early oesophageal carcinomas. Methods: A total of 111 patients with early oesophageal cancer (57 adenocarcinomas, 54 squamous cell carcinomas) had surgical resection with systematic lymphadenectomy (41 thoracoabdominal-TA, 52 transhiatal-TH and 18 with limited resection of the oesophagogastric junction- LROGJ). Results: In all patients, regardless from the surgical procedure, a complete resection (R0) was achieved. The median lymph node yield was significantly higher (p=0.0001) in TA patients (24 LN), compared with TH (14LN) and LROGJ (16LN). The median in hospital and ICU stay were shorter in patients with the LROGJ (12 and 2 days, respectively) compared with the TA (24 and 8 days) and TH patients (23 and 4 days). None of the 43 patients with high grade intraepithelial neoplasia (HGIEN) or oesophageal carcinoma limited to the mucosa had lymphatic spread, as compared with 15 of 68 (22.1%) with affection of the submucosa. Although lymph node metastases were usually limited to locoregional lymph node stations, two patients had metastases in distant lymph nodes (pM1a) The infiltration of the submucosa was accompanied with significant worsening of the overall survival (pT1a vs. pT1b; p=0.002). Multifocal neoplasia was detected in three patients with SCC HGIEN (30%) but not in AC HGIEN! Nine out of 44 (20.4%) patients with early SCC had multifocal neoplasia, compared to 6 out of 53 (11.3%) patients in AC (p=0.322). The sensitivity of the preoperative tumour dept staging (endoscopic ultra sound - EUS; and CT) was astonishing low (only 50% for cT1b), as was the specificity (66.7% for cT1a and only 87.5% for cT1b). On multivariate analysis, only histological tumor type (AC) was independent predictor of survival. Conclusions: Considering the limitations and pitfalls of endoscopic and classical resectional procedures, the quest for alternative and “patient tailored” treatment in patients with early oesophageal carcinoma carries on. A valuable alternative can be the limited resection of the oesophago-gastric junction under sparing of the healthy oesophagus and stomach. No significant financial relationships to disclose.

Abstract
BACKGROUND The prevalence of morbid obesity and its sequelae is increasing in Germany, Europe and worldwide. Bariatric surgery is thus gaining in importance for the treatment of patients with malignant obesity. Creation of a gastric bypass is one of the most frequently performed procedures for obesity. DISCUSSION The gastric bypass has been used -since 1966 as a surgical means of weight reduction in obese patients. In the mean time various modifications have been developed. Thus, for example, the laparoscopic procedure represents the current standard. After the operation most patients experience an excess weight loss (EWL) of between 61 and 83 %. The comorbidities of obesity are also markedly improved and in a high percentage even cured after the operation. It is worthy of note that diabetes mellitus type II improves shortly after the operation even before any weight loss has occurred. The suggests that the operation induces more than "just" a loss of weight. CONCLUSION For decades the gastric bypass has been a well known standard operation of overweight and, in addition to the reduction in weight, is also a therapy for diabetes mellitus -type II.

Abstract
In times of plentiful nutrition an environmental advantage turns into a problem - obesity. Apart from an increase in morbidity and overall mortality the development of osteoarthrosis is well documented. Pre-arthrotic conditions may arise from trauma and can lead, depending on the pattern of injury, to full-blown arthrosis. The presence of obesity can play the role of a relevant progressive factor in this setting. Here we report about the case of an obese man (BMI 53.5 kg/m(2)), who suffered a fracture of the femoral head with acetabular participation (Pipkin IV) as well as a fracture of the tibial plateau. Operative management and rehabilitation were followed by gastric bypass surgery for weight reduction. The case is discussed with regard to the present literature.

Abstract
Blood glucose measurements are generally accepted components of a modern diabetes self-management. The value of self-monitoring of blood glucose (SMBG) is, however, discussed controversially and only a few studies addressed the efficacy of SMBG under real-life conditions so far. In order to investigate whether the frequency of SMBG is related to long-term metabolic control, data from the DPV-Wiss-database, a standardized,prospective, computer-based documentation of diabetes care and outcome, were analyzed for patients with type 1(n = 19,491) and type 2 (n = 5,009) diabetes from 191 centers in Germany and Austria. Local HbA1c reference ranges were mathematically adjusted to the DCCT reference. For each patient, data from the most recent year of diabetes care were used. On average,patients with type 1 diabetes performed 4.4 blood glucose measurements/day. Corrected for age, gender, diabetes duration,on intensified (>or=4 daily injections or CSII) therapy (HbA1c reduction of 0.32% for one additional SMBG/day) compared to patients on conventional (1-3 daily injections) therapy(HbA1c-reduction of 0.16% for one additional SMBG/day). In 2,021 patients with insulin-treated type 2 diabetes (2.7 measurements/day), more frequent SMBG was associated with better metabolic control (HbA1c-reduction of 0.16% for one additionalSMBG/day, p < 0.0001), while in 2,988 patients on OAD or diet alone (2.0 measurements/day), more frequent blood glucose measurements were associated with higher HbA1c-levels(HbA1c-increase of 0.14% for one additional SMBG/day,p < 0.0001). These data indicate that more frequent SMBG are associated with better metabolic control in both, patients with type 1 and insulin-treated type 2 diabetes. Since no benefit ofSMBG on metabolic control was found in patients with type 2 diabetes on OAD or diet alone, SMBG should primarily be recommended for those patients with suboptimal metabolic control whereas the benefit of SHBG in non-insulin-treated patients with adequate HbA1c-levels remains uncertain.insulin therapy and center difference, the SMBG frequency was associated with better metabolic control (HbA1c-reduction of0.26% for one additional SMBG/day, p < 0.0001).

Abstract
Grazing-incidence small-angle X-ray or neutron scattering of thin polymer films reveals information about the ordering and preferential orientations of the phase-separated microdomains within the films. The grazing-incidence geometry enhances the surface sensitivity; however, the scattering has to be treated within the framework of the distorted-wave Born approximation. In this work, the case of thin films with lamellar mesostructure is studied, where the orientation of the lamellae is either perpendicular or parallel to the film interfaces. For perpendicular lamellae, Bragg rods are found, which are extended along the film normal, whereas for parallel lamellae, peaks along the film normal appear. The positions of the maxima present in the latter case are explained by accounting for refraction at the film surface and reflection at the film–substrate interface. The results are relevant for thin films of lamellar diblock copolymers.

Abstract
AIMS Thymidylate synthase (TS) and tumor suppressor p53 are two proteins with an influence on tumor resistance to radio-chemotherapy that is well known. For this reason we tested the effect of TS and p53 expression on clinical outcome (tumor recurrence and survival) in patients after curative tumor resection, especially in patients who received adjuvant radio-chemotherapy. PATIENTS AND METHODS A total of 120 patients with colorectal cancer were included in the study. A curative resection was possible in 83 patients, and 30 of this group received adjuvant therapy. For the immunohistochemical staining of tumor specimens, monoclonal antibody (mAb) TS 106 against TS and mAb DO-1 against p53 protein were used. TS positivity was defined as a moderate to high staining intensity in the cytoplasma of cells and p53 positivity as nuclear staining of tumor cells in >10% of these cells. RESULTS Thymidylate synthase immunoreactivity was found in 59% of all cases and p53 staining in 51%. No relation between clinicopathological features and p53 expression was found in contrast to TS expression, where a highly significant association of TS-positive cases with tumor invasion (pT) was observed. Curatively resected patients with a TS-positive tumor developed tumor recurrence/distant metastases significantly more often than TS negative tumors. The same result was found when comparing p53-positive with p53-negative tumors and TS+/p53+ with TS-/p53- tumors. TS expression was highly significantly associated with poor survival and was the strongest independent prognostic factor in multivariate analysis, followed by lymph node status. CONCLUSION Thymidylate synthase expression seems to be an independent prognostic factor and a possible predictor of tumor recurrence in patients with colorectal cancer.

Abstract
A quantum state can be understood in a loose sense as a map that assigns a value to every observable. Formalizing this characterization of states in terms of generalized probability distributions on the set of effects, we obtain a simple proof of the result, analogous to Gleason's theorem, that any quantum state is given by a density operator. As a corollary we obtain a von Neumann-type argument against noncontextual hidden variables. It follows that on an individual interpretation of quantum mechanics the values of effects are appropriately understood as propensities.

Abstract
Cytotoxic T lymphocyte (CTL) clones directed against autologous renal-cell carcinoma (RCC) cell lines were generated by mixed lymphocyte/tumor-cell culture (MLTC) using peripheral blood lymphocytes (PBL). A CD8+, CD4- CTL clone MZ1257-CTL 5/30 with high cytolytic activity for the autologous tumor cell line MZ1257-RCC was established. No lysis of the autologous EBV-transformed B lymphocytes (EBV-B) or K562 cells was observed. A panel of HLA-A2-matched allogeneic RCC lines was recognized by CTL 5/30. Further specificity analysis showed a cross-reactivity with HLA-A2-matched allogeneic tumor cells of various origins, especially melanoma. CTL 5/30 was also cross-reactive with several HLA-A2-positive allogeneic normal kidney cells in culture. The restriction element identified for CTL 5/30 was HLA-A2, as shown by blocking of cytotoxicity using an anti-HLA-A2 monoclonal antibody (MAb) and by resistance of an HLA-A2-negative melanoma variant SK29-MEL. 1.22 against lysis by CTL 5/30. In this report we demonstrate HLA-A2-restricted recognition of a T-cell-defined antigen on autologous renal-cancer cells. This antigen is also expressed and recognized in association with HLA-A2 on normal kidney cells in culture and other HLA-A2-positive tumor cells. It may therefore be a normal differentiation antigen to which tolerance is incomplete in the renal-cell cancer system investigated.

Abstract
Previous research on the effects of adjuvant treatment for women with operable breast cancer focused exclusively on disease-free and overall survival. In this study we evaluate life quality of premenopausal node-positive breast cancer patients receiving adjuvant chemotherapy for at least three months. For the first time, a modified latent variable model is used to assess treatment outcome in a prospective clinical trial. This poses a number of econometric problems which did not occur in the preceding studies. One of them is how to deal with patients whose records are incomplete. The data are provided by the International Breast Cancer Study Group (study VI). The results indicate that the lowest dose treatment improves life quality faster than the remaining three alternatives. At the end of the 24 months observation period no significant differences between the four treatment options remain. Although the lowest dose treatment is also the least costly no definite conclusion regarding cost-effectiveness can be drawn at this stage since survival data is not yet available.

Abstract
Increases in the activity of efferent cardiac sympathetic nerves by 35 +/- 9% were induced by 60 s bilateral occlusion of the common carotid arteries (BCO) in anesthetized dogs. Under control conditions the reflex rise in sympathetic nerve activity enhanced left ventricular pressure (115 +/- 4 mm Hg) by 47% and regional myocardial oxygen consumption (9.7 +/- 1.1 ml/min.100 g) by 56%. Simultaneously, end-diastolic circumflex coronary resistance (0.99 +/- 0.11 mm Hg.min.100 g/ml) decreased by 16%. After exhaustion of coronary dilator reserve by production of a severe coronary stenosis, BCO enhanced left ventricular pressure (107 +/- 4 mm Hg) by 49%, oxygen consumption of the poststenotic area (7.6 +/- 0.8 ml/min.100 g) increased by 21%, and circumflex coronary resistance (0.54 +/- 0.05 mm Hg.min.100 g/ml) also increased by 19%. The reflex increase in coronary resistance during BCO was abolished after infusion of the alpha 2-adrenoceptor antagonist rauwolscine (0.2 mg/kg i.v.). Administration of rauwolscine, however, did not prevent the reflex increase of left ventricular pressure and regional myocardial oxygen consumption. Comparable increases in poststenotic coronary resistance during BCO were found in dogs which either received propranolol (2 mg/kg i.v.) or in which the reflex rise in mean aortic pressure was limited to 13 +/- 3 mm Hg. In both experimental groups, rauwolscine also effectively prevented the BCO-induced rise in coronary resistance. In contrast, the reflex increase of total peripheral resistance was not significantly reduced by rauwolscine, but was blunted after additional administration of the selective alpha 1-adrenoceptor antagonist prazosin (1.2 mg/kg i.v.). We conclude that: 1) Poststenotic coronary vasoconstriction occurs during shortlasting increases in efferent cardiac sympathetic discharge within the physiological range. 2) This increase in poststenotic coronary resistance is significantly reduced after administration of the alpha 2-adrenoceptor antagonist rauwolscine. 3) In contrast to poststenotic coronary resistance, functionally innervated alpha 2-adrenoceptors are of minimal importance for the reflex increase in total peripheral resistance.

Abstract
The efficacy of nebulised sodium cromoglycate (SCG) used as a prophylactic treatment of wheezy bronchitis in children aged 1 to 4 years was evaluated in a multicentre double-blind placebo controlled, group comparative study. Fifty-four patients completed the 10-week trial (29 treated with SCG and 25 treated with placebo), preceded by 4-8 weeks baseline. Nebulised SCG did not prove significantly superior to placebo in reducing day wheezing, day coughing, or sleep disturbance due to wheezing or coughing at night. Neither was there significant difference in the use of supportive medicine (beta 2-agonist and theophylline) between the groups. Extra doctor visits, hospital admissions, and parental preference did not show significant difference either.

Abstract
Forty elderly patients (mean age 78.9 years) undergoing acute surgery for hip fracture were given at random either spinal analgesia with bupivacaine 0.75% or general anaesthesia with diazepam, fentanly and N2O/O2. Mental function was studied pre-operatively with an abbreviated mental test and 1 week and 3 months postoperatively in both groups. Mortality and number of complications was similar in the two groups, but a shorter time of ambulation was seen in the spinal group compared to the general anaesthetic group. No persistent impairment in mental function was found after acute hip surgery under spinal or general anaesthesia and the only advantage of regional technique was a shorter time of ambulation.
