Abstract
Larger penis size has been associated with a sign of strength, masculinity, and social standing. Little study has examined the relationship between men's penis size and their partners' sexual satisfaction. The purpose of the present study was to detail and evaluate the effect of penis size on partner sexual satisfaction with a design of narrative literature review. A systematic search of MEDLINE/PubMed was conducted to discover relevant studies on this issue. Currently, available studies show incomplete results between the penis size and partners' sexual satisfaction and are limited by methodological drawbacks, including small sample's size. The link between penis size and the sexual satisfaction of the partner need to be supported by more robust scientific evidence.

Abstract
OBJECTIVES To evaluate whether continuing the antiplatelet drug acetylsalicylic acid≤100mg (ASA) during Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) increases the risk of peri-and postoperative hemorrhagic complications and overall morbidity. Indeed, guidelines recommend interrupting antiplatelet therapy before radical cystectomy; however, RARC with ICUD is associated to reduced estimated blood loss and blood transfusions compared to its open counterpart. METHODS Data from a multicentric European database were analyzed. All participating centers maintained a prospective database of patients undergoing RARC with ICUD. We identified patients receiving antiplatelet therapy by acetylsalicylic acid ≤100mg. Patients were divided into three groups: those not taking acetylsalicylic acid (no-ASA), those where ASA was continued perioperatively (c-ASA) and those where ASA was interrupted perioperatively (i-ASA). Estimated blood loss and peri-and post-operative transfusions were recorded. Hemorrhagic complications, ischemic, thrombotic and cardiac morbidity was recorded and classified using the Clavien-Dindo score by a senior urologist. RESULTS 640 patients were analyzed. Patients on acetylsalicylic acid were significantly older and had more comorbidities. No significant difference was found for estimated blood loss between no-ASA, c-ASA and i-ASA (280 vs. 300 vs. 200ml respectively; P = 0.09). Similarly, no significant difference was found for intraoperative (5% vs. 9% vs. 11%; P = 0.07) and postoperative transfusion rate (11% vs. 13% vs. 18%; P = 0.17). Higher ischemic complications were noted in the i-ASA group compared to no-ASA and c-ASA (4% vs. 0.6% vs. 1.4%; P = 0.03). On uni and multivariate logistic regression, continuing acetylsalicylic acid was not significantly associated to either major complications or post-operative transfusions. CONCLUSIONS Peri-operative acetylsalicylic acid continuation in RARC with ICUD does not increase hemorrhagic complications. Interrupting acetylsalicylic acid peri-operatively may expose patients to a higher risk of ischemic events.

Abstract
Background: Caregivers play a key role in the success of trauma-focused cognitive behavioural therapy (TF-CBT). Yet, the effect of their alliance on treatment outcomes besides the other parties in treatment has hardly been studied. Objective: This study examined the working alliance (WA) of therapists, patients and caregivers in TF-CBT and its contribution on treatment outcome over time. Methods: N = 76 children and adolescents (mean age = 12.66 years, range 7-17, M/F ratio: .43) participated in the TF-CBT arm of a randomized controlled trial. The WA was assessed with the Working Alliance Inventory Short Version (WAI-S) at two measurement points, while symptom level of posttraumatic stress symptoms (PTSS) was assessed with the Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA). Paired sample t-tests, intraclass correlations (ICC), and mixed-effects regression models for longitudinal data were performed. Results: The alliance rating was high across all informants, with caregivers achieving the highest rating. The average level of cross-informant agreement on the alliance was low between therapists and caregivers (ICC = .26) and moderate between therapists and patients (ICC =.65). A significant contribution of an alliance improvement to the reduction of PTSS over time was found in each of the two tested models: therapists with patients model (b = .682) and therapists with caregivers model (b = .807). However, these effects were not detected with all four perspectives in one comprehensive model. Conclusion: In summary, the potential of caregivers' views should receive more attention in the therapeutic process of trauma-focused therapy.

Abstract
Background: Health promotion and prevention are key elements of Bavarian health policy and are currently being re-oriented along the framework of the "Bavarian Prevention Plan". In this context, a stock taking of prevention and health promotion in Bavaria was conducted with the aim to contribute to the continued strategic and quality-orientated development of this field. Methods: The investigation was restricted to activities of primary prevention and health promotion with a focus on the action areas of the Bavarian Prevention Plan. The prevention actors, not projects, were the smallest units that were surveyed. During the 3-month field phase in 2014/2015, 595 prevention players were contacted and asked to complete an online questionnaire on their activities and target groups as well as quality and structural aspects. In addition, 9 expert interviews were conducted in an urban and a rural area in order to explore the field of small commercial and civic prevention actors. Results: 135 prevention players took part in the survey (return rate 23%). The most commonly cited themes of activities are health literacy (62% of players) and mental health (58%). The target groups are often broadly defined, gender specific measures and those for socially disadvantaged groups are comparatively rare. Provision of health-related information is the most commonly used approach (58-69% of players depending on the action area), least used are community work approaches (9-12%). 77% of the respondents state to use models of best practice and 55% scientific results in the development of measures; 43% conduct outcome evaluations and 80% take part in committee work and networks. The latter are mainly used to exchange information (90% of actors), 55 and 54% state to use them for joint planning and delivery of interventions, respectively. Conclusions: The most important prevention players took part in the survey. Methodologically it proved difficult to achieve a meaningful depiction of central aspects of the prevention scene via a quantitative survey approach. There is a lack of well-tried instruments and approaches for such cross-agency surveys. Nevertheless, the study allows trend statements on the spectrum, structure and quality of prevention in Bavaria. Thus, a starting line for the implementation of the Bavarian Prevention Plan as well as the basis of prevention reporting as intended by the new national prevention law could be established.

Abstract
IntroductionRecent data support the view that the neurodegeneration underlying sporadic Alzheimer's Disease (AD) is in part related to brain insulin deficiency and brain insulin resistance. There is a higher incidence of AD in patients with diabetes mellitus type II (T2D) and both diseases show a decline in memory function. In a preceding trial intranasal insulin improved memory function in healthy volunteers so that an increase of central-nervous insulin concentration may improve cognitive function in both amnestic patient groups.AimsWe want to analyse the effects of intranasal insulin on patients with early Alzheimers's disease (eAD) and patients with T2D in the state of amnestic mild cognitive impairment (aMCI).MethodsRecruitment of 30 patients with eAD, 30 patients with T2D in aMCI state and 30 age-matched healthy controls. All patients undergo a run-in period of 2 weeks with 4 × daily administration of placebo. It follows a double blinded trial with daily intranasal administration of 4 × 40 I.U. insulin vs. placebo for 8 weeks and another 8 weeks of follow-up. At 4 defined time points memory function is assessed by word lists comprising 30 items of emotional, nutritional and neutral content which have to be memorized and are recalled after one week. To assess structural changes of the brain, a quantitative analysis for hippocampal N-acetyl-aspartate, choline and creatine is performed by 3 Tesla magnetic resonance spectroscopy.Results: Since the study has not finished yet, we present experiences from the initiation and the beginning phase.

Abstract
Patients' satisfaction has become a central concept in quality assurance. Despite progress in research in this area is still a lack of data for geriatric patients. Referring to the consumer model, satisfaction can be described as a difference between expectations and assessed performance. The aim of this study is to analyze satisfaction among geriatric patients in an in-patient setting. A personal interview was performed 1-2 days before discharge. Patients suffering for dementia or with problems to communicate were excluded. 124 of 268 geriatric patients who were discharged in 2003 were included (inclusion rate 46.3%). 119 were willing to participate (response rate 96.0%). Respondents were between 61 and 96 years old, 39% were male and 42% had serious functional limitations at time of admission. Multiple linear regression analysis revealed three significant predictors of a combined index of satisfaction and expectations: a) quality of hotel services; b) experience of neglect; c) provision of medical information and skills. In summary, standardized personal questionnaires can provide valid and reliable data of geriatric patients. Satisfaction of elderly patients is negatively affected by neglect and positively influenced by provision of medical information and a good hotel services.

Abstract
Quality changes of strawberries during storage can be caused both by microbiological and physiological processes. There is little known about the possible contribution of microbiological processes to the quality degradation of strawberries. In this study, quality of strawberries during storage was evaluated by analytical and sensorial analyses. It was the aim to investigate the influence of microbiological activity on the changes of different quality factors of strawberries during storage. During storage at 7 degrees C, quality was mainly determined by the odor and by visual defects. Regarding the odor, highly microbiologically contaminated late-season strawberries packaged in air at 7 degrees C became sensorially unacceptable due to the presence of high amounts of ethyl acetate. This could be attributed to the yeast proliferation: at yeast concentrations above 5.0 log cfu/g, an increase in ethanol was detected in the headspace of the strawberries. It was shown that ethanol was converted to ethyl acetate by strawberries resulting in an unacceptable odor. In an experiment with low microbiologically contaminated early-season strawberries, not reaching the above mentioned yeast counts, less ethyl acetate was detected which resulted in strawberries that were sensorially acceptable during the whole storage period (12 days). Strawberries packaged in modified atmosphere conditions showed a different quality pattern due to the effect of decreased O2-concentrations on both microbiological and physiological processes. This paper demonstrates that also microbiological processes on strawberries should be considered as they could play an important role in the sensorial quality when interacting with physiological processes.

Abstract
Changes of different quality factors of strawberries have been described until now from a physiological point of view. Possible effects on quality caused by yeast proliferation have not been described. To elucidate the metabolic activity of yeasts (i.e. Debaryomyces melissophilus, Rhodotorula glutinis, Cryptococcus laurentii), isolated from strawberries, they were inoculated on a simulation medium of strawberries (strawberry-agar). Their activity was measured by analysing and correlating microbiological counts, metabolite concentration in the headspace as well as in the medium, and sugar consumption. The isolated yeasts from strawberries could grow on the strawberry-agar, both under air conditions and modified atmosphere (MA) conditions. The maximum count for the yeasts reached 7.5-8.5 log cfu cm(-2) (air conditions) and 5.6-6.4 log cfu cm(-2) (MA conditions). Production or consumption of a number of compounds could be detected when microbial counts reached levels between 4.7 log cfu cm(-2) and 8.5 log cfu cm(-2) depending on species and atmospheric conditions. A range of volatile organic compounds, produced by the yeasts, was detected: acetone, ethyl acetate, ethanol, isopropyl acetate, ethyl butyrate, 1-propanol, 2-methyl-1-propanol, 1-butanol, 2-methyl-1-butanol, 3-methyl-1-butanol, 1-hexanol and hexyl acetate. These compounds are able to influence the sensory properties of strawberries. A simultaneous decrease in sugar concentrations (sucrose, glucose, fructose) was observed. When ethanol reached high concentrations, ethyl acetate and ethyl butyrate were produced. This production can be attributed to a detoxification of ethanol by yeasts. The fermentative metabolism of yeasts during aerobic conditions could be explained by the Crabtree effect. As the detected volatile organic compounds produced by yeasts are also found in fresh strawberries, it can be concluded that these compounds are produced both by microbiological and physiological processes.

The intracellular distribution of gelsolin in NIH 3T3 cells was examined by immunostaining using affinity-purified polyclonal gelsolin antibodies before and after induction of apoptosis by serum withdrawal. Serum deprivation induced detachment of an increasing number of NIH 3T3 cells, but also apoptosis in attached cells as verified morphologically by chromatin condensation, nuclear fragmentation and labelling of their periphery by FITC-annexin V. Ongoing apoptosis was also demonstrated by activation of caspase-3 activity and chromatin cleavage into high-molecular-mass fragments, although no internucleosomal chromatin degradation (DNA-ladder formation) was detected. When cells were maintained in the presence of 10% foetal calf serum, gelsolin immunoreactivity was evenly distributed in the cytoplasm. No obvious co-localisation of gelsolin and the actin-containing stress fibres was detected under these conditions. At day one after serum withdrawal, a redistribution of gelsolin to actin filaments was detected within a few attached cells by double fluorescence staining. The number of cells exhibiting this redistribution increased at days two to four. In addition, the stress fibres increased in thickness and their length was continuously reduced. At day four, many cells contained shortened stress fibres, which had lost their longitudinal orientation. Additionally, the cytoplasm of a number of attached cells was highly condensed around their nuclei and a homogenous distribution of both gelsolin and actin was detected in the remaining cytoplasmic rim. Up to day two, these effects were reversible after re-addition of serum to attached cells. A similar redistribution of gelsolin immunore-activity was observed after induction of apoptosis by cycloheximide, but not after initiation of necrosis by hydrogen peroxide. In NIH 3T3 cells no alteration in the expression of gelsolin at the level of protein (Western blot) or specific mRNA (Northern blot) was observed after serum withdrawal. Using Western blotting, no proteolysis of gelsolin was detected up to day 4, although caspase-3 activity was found to have increased fivefold after serum withdrawal. These results suggested that in these cells F-actin severing might occur in the absence or advance of gelsolin cleavage by caspases. Intact gelsolin on its own may be sufficient for the dissolution of the microfilaments, since micro-injection of gelsolin into primary bovine lens cells led to a transient disappearance of the stress fibres and to a reduction of their attachment area to the substratum. In NIH 3T3 cells similar effects of micro-injected gelsolin were only observed at day one after serum withdrawal.

Abstract
BACKGROUND In Germany, the situation of geriatric medicine has improved significantly over the past few years. Until now, though, there was little information available on the structure of the clinical geriatric departments. Since this information is vital to assess whether these departments can provide high-quality services, the German Federal Association of Clinical Geriatric Departments conducted a survey among its members. The goal was to gain deeper insight into the structure of the geriatric acute hospitals and rehabilitation units. METHODS In 1999, member institutions were mailed a standardized questionnaire and all institutions (100%) returned the questionnaire to the association's central office. To increase data quality, data were screened and reports were generated for each institution. These reports were returned to the institutions which were asked to verify them. RESULTS This article shows that in 1998 acute geriatric hospitals (n = 89), rehabilitation units (n = 52), acute day clinics (n = 45) and rehabilitation day clinics (n = 26) had--on average--60/60/15.3/14 beds/places and 828.15/677.3/164.2/125.9 patients. Occupancy rates averaged out at 88.7%/84.3%/86.4%/63.7% and daily hospital rates at DM 401.4/322.4/293.8/243.2. Basically, all geriatric institutions included in this survey had a multi-professional geriatric team. Patient-to-staff ratios for psychologists, social workers, ergo-, physio- and speech therapists were better in day clinics than in in-patient clinics and better in rehabilitation units than in acute hospitals. Geriatric institutions mainly focused on the treatment of neurological deficits. Most patients were admitted from other hospitals and discharged to their private residence. CONCLUSIONS The results of this survey indicate that especially the acute hospitals are often not sufficiently staffed. Moreover, further efforts are necessary to clarify the indications for and modalities of geriatric day clinic treatment and rehabilitation. The data also show that a categorical distinction between geriatric acute hospitals and rehabilitation units is not possible. However, further data collection and more detailed analyses are needed.

Abstract
OBJECTIVE The purpose of the study was to show that stereotactic breast biopsy can be performed effectively and accurately using add-on stereotactic equipment when it is performed with the patient in a decubitus or recumbent position. MATERIALS AND METHODS We retrospectively reviewed the results of 225 stereotactic core breast biopsies performed during a 42-month period. The biopsies were performed using a reclining mammography chair and add-on stereotactic equipment. Procedures were performed with the patient in the right or left lateral decubitus position or upright. Patients with benign biopsy results were followed up mammographically at 6 months initially, then yearly. RESULTS Of the 225 lesions biopsied stereotactically, 205 lesions (91%) were biopsied with the patient in the decubitus (right or left) position and 20 (9%) biopsied with the patient upright. Pathology results were classified as abnormal in 45 lesions (20%) and normal in 180 lesions (80%). All but one of the abnormal lesions were followed up with surgical excision. One hundred thirty-four of the 180 benign lesions have been followed up with at least one 6-month mammogram (follow-up range, 6-40 months), and none of the lesions has been subsequently proven malignant. CONCLUSION Stereotactic core biopsy can be performed effectively and accurately using standard add-on equipment when it is performed with the patient in the decubitus position. This approach obviates the use of dedicated prone stereotactic equipment.

Abstract
Mesenchymal chondrosarcomas are small-cell malignancies named as chondrosarcomas due to the focal appearance of cartilage islands. In this study, the use of in situ detection techniques on a large series of mesenchymal chondrosarcoma specimens allowed the identification of tumor-cell differentiation pathways in these neoplasms. We were able to trace all steps of chondrogenesis within mesenchymal chondrosarcoma by using characteristic marker genes of chondrocytic development. Starting from undifferentiated cells, which were negative for vimentin and any other mesenchymal marker, a substantial portion of the cellular (undifferentiated) tumor areas showed a chondroprogenitor phenotype with an onset of expression of vimentin and collagen type IIA. Cells in the chondroid areas showed the full expression panel of mature chondrocytes including type X collagen indicating focal hypertrophic differentiation of the neoplastic chondrocytes. Finally, evidence was found for transdifferentiation of the neoplastic chondrocytes to osteoblast-like cells in areas of neoplastic bone formation. These results establish mesenchymal chondrosarcoma as the very neoplasm of differentiating premesenchymal chondroprogenitor cells. The potential of neoplastic bone formation in mesenchymal chondrosarcoma introduces a new concept of neoplastic (chondrocytic) osteogenesis in musculoskeletal malignant neoplasms, which qualifies the old dogma that neoplastic bone/osteoid formation automatically implies the diagnosis of osteosarcoma.

Abstract
Chondroblastoma is defined as a 'benign tumour, characterized by highly cellular and relatively undifferentiated tissue composed of rounded or polygonal chondroblast-like cells' and the 'presence of cartilaginous intercellular matrix' (WHO). An extensive analysis of the extracellular matrix composition and gene expression pattern of a large series of chondroblastoma cases shows, however, that type II collagen, which is the main component of any cartilage matrix, is not expressed by the neoplastic cells of this tumour entity and is not deposited into the extracellular tumour matrix. Instead, osteoid and fibrous matrix is formed, with its typical biochemical composition. The multifocal expression of aggrecan proteoglycan in most chondroblastomas explains the bluish, pseudo-chondroid appearance of some of the matrix-rich areas of chondroblastomas. This study did not show chondroid matrix formation or chondroblastic cell differentiation in chondroblastomas, suggesting that chondroblastoma should be classified as a specific bone-forming, rather than cartilage-forming neoplasm.

Abstract
Gross cystic disease fluid protein 15 (GCDFP-15) is a major protein component of benign breast gross cysts. It is also found in approximately 50% of all breast cancer specimens. Androgen receptor (AR) mediated regulation of GCDFP-15 expression was investigated in the AR-positive human mammary cancer cell lines MFM-223 and ZR-75-1. Proliferation of MFM-223 and ZR-75-1 cells is inhibited by androgens. Ten nM 5alpha-dihydrotestosterone stimulated the expression of GCDFP-15 mRNA in MFM-223 (ca. 3-fold) and ZR-75-1 cancer cells (ca. 30-fold) as well as the secretion of GCDFP-15 into the culture medium. Competition experiments with DHT and the antiandrogens hydroxyflutamide and casodex confirmed the involvement of the AR in the regulation of GCDFP-15. Both antiandrogens inhibited GCDFP-15 mRNA expression even in the absence of DHT. AR mRNA was down-regulated in MFM-223 and ZR-75-1 cells (80 and 20% of the control, respectively) during incubation with DHT. Our data demonstrate the effective inhibition of GCDFP-15 expression by pure antiandrogens.

Abstract
MFE-280 endometrial cancer cells express PP14 (placental protein 14) in vitro. PP14 is normally found in the secretory endometrium and in placental tissue. MFE-280 cells, which are tumorigenic in nude mice, were derived from a recurrent, poorly differentiated endometrial carcinoma. The cells were initially grown in suspension culture and later transferred to monolayer cultures. Karyotyping revealed near-diploidy with a complex heterogeneous aberration pattern. MFE-280 cells were positive for the cytokeratins 7, 8, 18 and 19 as well as for vimentin. The expression of PP14 in MFE-280 cells was demonstrated by immunochemistry and reverse transcriptase--polymerase chain reaction. PP14-mRNA was also detected in one out of five endometrial cancer specimen. In tumor tissue the expression of PP14 was not dependent on progestins.

Abstract
The hepatic clearance rate and secretion rate mainly determine peripheral plasma concentrations of regulatory peptides released from the gastrointestinal tract. In the present study hepatic extraction of peptide YY (PYY) during a single passage was investigated in the in situ perfused rat liver excluding modulating actions of circulating hormones. During perfusion of low amounts of PYY (50, 100, 500 pmol l-1), peptide concentrations in the portal vein (5.1 +/- 4.6, 98.1 +/- 2.6, 558 +/- 13.6 pmol l-1) and in the hepatic vein (50.2 +/- 1.4, 88.6 +/- 2.2, 503 +/- 18.1 pmol l-1 was only 22.1%. PYY had no influence on hepatic glucose and lactate production, portal flow as well as bile flow and bile acid secretion at these concentrations. PYY seems to traverse the liver almost intact and reaches the target organs without any significant hepatic extraction. Concomitant studies on metabolic and excretory functions of the liver showed no effect of PYY.
