Abstract
Halogenated organic compounds are widespread, and decades of heavy use have resulted in global bioaccumulation and contamination of the environment, including water sources. Here, we introduce the most common halogenated organic water pollutants, their classification by type of halogen (fluorine, chlorine, or bromine), important policies and regulations, main applications, and environmental and human health risks. Remediation techniques are outlined with particular emphasis on carbon-halogen bond strengths. Aqueous advanced redox processes are discussed, highlighting mechanistic details, including electrochemical oxidations and reductions of the water-oxygen system, and thermodynamic potentials, protonation states, and lifetimes of radicals and reactive oxygen species in aqueous electrolytes at different pH conditions. The state of the art of aqueous advanced redox processes for brominated, chlorinated, and fluorinated organic compounds is presented, along with reported mechanisms for aqueous destruction of select PFAS (per- and polyfluoroalkyl substances). Future research directions for aqueous electrocatalytic destruction of organohalogens are identified, emphasizing the crucial need for developing a quantitative mechanistic understanding of degradation pathways, the improvement of analytical detection methods for organohalogens and transient species during advanced redox processes, and the development of new catalysts and processes that are globally scalable.

Abstract
AbstractWe analyzed the enormous scale of global human needs, their carbon footprint, and how they are connected to energy availability. We established that most challenges related to resource security and sustainability can be solved by providing distributed, affordable, and clean energy. Catalyzed chemical transformations powered by renewable electricity are emerging successor technologies that have the potential to replace fossil fuels without sacrificing the wellbeing of humans. We highlighted the technical, economic, and societal advantages and drawbacks of short- to medium-term decarbonization solutions to gauge their practicability, economic feasibility, and likelihood for widespread acceptance on a global scale. We detailed catalysis solutions that enhance sustainability, along with strategies for catalyst and process development, frontiers, challenges, and limitations, and emphasized the need for planetary stewardship. Electrocatalytic processes enable the production of solar fuels and commodity chemicals that address universal issues of the water, energy and food security nexus, clothing, the building sector, heating and cooling, transportation, information and communication technology, chemicals, consumer goods and services, and healthcare, toward providing global resource security and sustainability and enhancing environmental and social justice.

Abstract
Abstract
Objective
The paradigm shift according to the principles of Value-Based Healthcare is receiving growing attention. In Orthopedic Trauma care, there are no defined standards to provide an incentive system to recompensate for quality instead of quantity. The definitions of quality from the patient's view have to be validated and included in the reimbursement cycle. In our Department, we now have fully standardized and structured documentation and outcome measurement workflow from the clinical point of view.
Methods
We set up a Fracture Registry with a REDCap® Database to document every patient with surgical treatment. Included are all surgically treated fractures of the extremities, excluding the hand. Furthermore pelvic, acetabular, and periprosthetic fractures, joint dislocations, and tendon ruptures. With interfaces to our Clinical Documentation Systems, the administrative effort became very efficient. The interfaces provide a possibility to identify every patient with inclusion criteria and implement reminder feedback for Surgeons. We collect PROMs with the heartbeat-Software, and document CROMs with REDCap®. We merged these data using the software ‘R’. The documentation of each patient is completed with a database for Adverse Events.
Results
Data-entry rates were less than 50% in 2018 and have reached 99.1% for 2020 and 99.5% for 2021 for surgically treated fracture patients. Until the submission of this abstract, 2382 surgical procedures have been performed at our Department on 2073 hospitalized patients. 972 patients were included in the Fracture Registry (47%). In a feasibility study, we have merged clinical data with the PROMs of patients treated for distal radius (DR) and proximal humerus (PH) fractures. The baseline values for DR of the quality-of-life questionnaire EQ5D was 0.83 (n=144), after 3months 0.9 (n=58) and 0.97 one year after treatment (n=6). Although not more than a trend, we realized the same pattern for PH-patients with an EQ5D-Baseline of 0.75 (n=63), three months values of 0.75 (n=58), and one-year results of 0.87 (n=6).
Conclusion
Collecting structured data allows combining routine clinical data with PROMs and CROMs. This information is of inestimable value to define the quality of care for Orthopedic Trauma Surgery. Our combination of Databases to collect diagnosis, subjective and objective outcome measures has been proven feasible and showed high data quality.

Abstract
Catalysis is essential to modern life and has a huge economic impact. The development of new catalysts critically depends on synthetic methods that enable the preparation of tailored nanomaterials. Pulsed laser in liquids synthesis can produce uniform, multicomponent, nonequilibrium nanomaterials with independently and precisely controlled properties, such as size, composition, morphology, defect density, and atomistic structure within the nanoparticle and at its surface. We cover the fundamentals, unique advantages, challenges, and experimental solutions of this powerful technique and review the state-of-the-art of laser-made electrocatalysts for water oxidation, oxygen reduction, hydrogen evolution, nitrogen reduction, carbon dioxide reduction, and organic oxidations, followed by laser-made nanomaterials for light-driven catalytic processes and heterogeneous catalysis of thermochemical processes. We also highlight laser-synthesized nanomaterials for which proposed catalytic applications exist. This review provides a practical guide to how the catalysis community can capitalize on pulsed laser in liquids synthesis to advance catalyst development, by leveraging the synergies of two fields of intensive research.

Abstract
SETTING One of the most serious problems in tuberculosis (TB) control is non-adherence to treatment. Several strategies have been developed to improve adherence and increase the cure rate. OBJECTIVE To systematically review interventions to improve adherence to anti-tuberculosis treatment. DESIGN We performed a systematic review and meta-analysis of 22 randomised clinical trials (RCTs) to ascertain whether providing directly observed treatment, short-course (DOTS), financial incentives, food incentives and/or patient education/counselling improved adherence to anti-tuberculosis treatment. The primary outcome was cure rate; secondary outcomes were default and mortality rates. Sources used were Medline (accessed via PubMed), Cochrane Central, LILACS (Literatura Latino Americana em Ciências da Saúde, Latin American and Caribbean Health Sciences Literature) and Embase from inception to October 2015. RESULTS A significant increase in cure rates, by 18% with DOTS and by 16% with patient education and counselling, was observed. In addition, the default rate decreased by 49% with DOTS, by 26% with financial incentives and by 13% with patient education and counselling. There was no statistically significant reduction in mortality rates with these interventions. CONCLUSION Use of DOTS and patient education/counselling significantly improved cure rates; DOTS, patient education/counselling and financial incentives led to a reduction in the default rate.

Abstract
Mycosis fungoides (MF) is a primary cutaneous T-cell lymphoma with unfavourable prognosis for patients with advanced stages of the disease. Refractory disease and advanced-stage disease require systemic therapy. We report on a rare case of an atypical predominantly CD8+ folliculotropic MF, a subtype of MF with poorer prognosis, in a 59-year-old woman. She was initially diagnosed with MF restricted to the skin, of T3N0M0B0/stage IIB according to the current World Health Organization-European Organisation for Research and Treatment of Cancer classification. First-line treatment with local percutaneous radiotherapy in combination with systemic interferon alfa-2a resulted in complete remission. However, 21 months later the disease progressed to T3N0M1B0/stage IVB with development of cerebral manifestation and thus very poor prognosis. Allogeneic stem cell transplantation (SCT) was not a therapeutic option due to the lack of a suitable donor. We initiated methotrexate and cytarabine chemotherapy, followed by high-dose chemotherapy with thiotepa and carmustine with autologous SCT. Despite rapid response and complete remission of the cerebral lesions, disease recurrence of the skin occurred soon after. Interestingly, readministration of interferon alfa-2a as a maintenance treatment after the salvage autologous SCT resulted in a durable complete remission during the follow-up period of currently 17 months after autologous SCT. What's already known about this topic? Mycosis fungoides is a primary cutaneous T-cell lymphoma with unfavourable prognosis for the advanced stages of the disease. A refractory course of disease requires systemic therapy. What does this study add? We report on an unusual case of a patient with mycosis fungoides with cerebral involvement, in which a durable complete remission was achieved upon autologous stem cell therapy and interferon alfa-2a maintenance therapy.

Abstract
Water oxidation is a key chemical transformation for the conversion of solar energy into chemical fuels. Our review focuses on recent work on robust earth-abundant heterogeneous catalysts for the oxygen-evolving reaction (OER). We point out that improvements in the performance of OER catalysts will depend critically on the success of work aimed at understanding reaction barriers based on atomic-level mechanisms. We highlight the challenge of obtaining acid-stable OER catalysts, with proposals for elements that could be employed to reach this goal. We suggest that future advances in solar fuels science will be accelerated by the development of new methods for materials synthesis and characterization, along with in-depth investigations of redox mechanisms at catalytic surfaces.

Abstract
Polycomb group (PcG) proteins comprise evolutionary conserved factors with essential functions for embryonic development and adult stem cells. PcG proteins constitute two main multiprotein polycomb repressive complexes (PRC1 and PRC2) that operate in a hierarchical manner to silence gene transcription. Functionally distinct PRC1 complexes are defined by Polycomb group RING finger protein (Pcgf) paralogs. So far, six Pcgf paralogs (Pcgf1-6) have been identified as defining components of different PCR1-type complexes. Paralog-specific functions are not well understood. Here, we show that Pcgf6 is the only Pcgf paralog with high expression in undifferentiated embryonic stem cells (ESCs). Upon differentiation Pcgf6 expression declines. Following Pcgf6 kockdown (KD) in ESCs, the expression of pluripotency genes decreased, while mesodermal- and spermatogenesis-specific genes were derepressed. Concomitantly with the elevated expression of mesodermal lineage markers, Pcgf6 KD ESCs showed increased hemangioblastic and hematopoietic activities upon differentiation suggesting a function of Pcgf6 in repressing mesodermal-specific lineage genes. Consistant with a role in pluripotency, Pcgf6 replaced Sox2 in the generation of germline-competent induced pluripotent stem (iPS) cells. Furthermore, Pcgf6 KD in mouse embryonic fibroblasts reduced the formation of ESC-like colonies in OSKM-driven reprogramming. Together, these analyses indicate that Pcgf6 is nonredundantly involved in maintaining the pluripotent nature of ESCs and it functions in iPS reprogramming.

Abstract
BACKGROUND The decline in the incidence of stillbirths in Germany has remained static in recent years. This study aims to analyse the current situation of data documentation and examination of stillbirths. Furthermore, possible stillbirth prevention strategies should be developed. METHODS Searches in the international peer-reviewed literature, retrospective data collection of 168 stillbirths in 8 hospitals, (in the area of Bonn) with subsequent statistical evaluation (descriptive statistics, t-test and binominal test) were undertaken. RESULTS This study shows considerable deficits in data documentation, interdisciplinary communication and postmortal examination. Only in 51.8% (87/168) of the cases was a certain or uncertain cause of death found (42.3% placental, 1.2% foetal, 3.6% chromosomal, 4.8% umbilical cord abnormalities). Severe foetal growth restriction (<5(th) percentile) was observed in 29.2%; 44.9% (22/49) of them died at the age of ≥36+0 weeks of gestation. CONCLUSION The first step to reduce the rate of stillbirths in Germany is to increase the identified causes of foetal death: Therefore, an interdisciplinary case report form was compiled to improve data collection and interdisciplinary collaboration. To standardise and complete postmortal management, an algorithm was created. The long-term aim is the development of a central data register for statistical analysis, to identify goals of research and to organise conferences with interdisciplinary reports of diagnostic findings.

Abstract
Accidental and nonaccidental spinal injuries are generally rarely seen in infants. If affected, vertebral bodies usually present compression fractures due to forced hyperflexion or hypertension. Radiographic examination of the infantile skeleton can reveal a radiolucent band running through a vertebral body. These so called vertebral clefts are mainly visualized in the lateral spinal radiograph. Usually they can be found in the 1st year of life. Radiological appearance of coronal clefts was compared to that of a traumatic vertebral compression fracture. Clefts were mostly localized in the lumbar spine and had a completely different radiological appearance comparing to a traumatic compression fracture. As coronal clefts can be seen as a result from a retarded ossification of the vertebral bodies in fetal development they are a physiological variant. Due to this different etiology they have to be distinguished from spinal signs of child abuse.

Abstract
Understanding the distance distribution and dynamics between moieties attached to the walls of a resorcin[4]arene cavitand, which is switchable between an expanded kite and a contracted vase form, might enable the use of this molecular system for the study of fundamental distance-dependent interactions. Toward this goal, a combined experimental and molecular dynamics (MD) simulation study on donor/acceptor borondipyrromethene (BODIPY) dye-labeled cavitands present in the vase and kite forms was performed. Direct comparison between anisotropy decays calculated from MD simulations with experimental fluorescence anisotropy data showed excellent agreement, indicating that the simulations provide an accurate representation of the dynamics of the system. Distance distributions between the BODIPY dyes were established by comparing time-resolved Förster resonance energy transfer experiments and MD simulations. Fluorescence intensity decay curves emulated on the basis of the MD trajectories showed good agreement with the experimental data, suggesting that the simulations present an accurate picture of the distance distributions and dynamics in this molecular system and provide an important tool for understanding the behavior of extended molecular systems and designing future applications.

Abstract
Angiotensin I-converting enzyme (kininase II, ACE, and CD143) availability is a determinant of local angiotensin and kinin concentrations and their physiological actions. Until now, it is unclear whether the decrease of pulmonary ACE activity in sepsis-described in clinical studies-is due to an enzyme compensatory downregulation (reduced ACE-mRNA expression) to shedding of ACE or endothelial damage. To address these questions, ACE distribution under septic conditions was studied in vitro by treating pulmonary microvascular endothelial cells (HPMEC) and human umbilical vein endothelial cells (HUVEC) with lipopolysaccharide from Escherichia coli (LPS). Primary isolated HUVEC and HPMEC were compared by detecting ACE activity, membrane-bound ACE, as well as shedding and mRNA production of ACE with and without LPS (1 ng/ml-1 μg/ml). ACE mRNA expression was detected by real-time PCR, and shedded ACE was measured in cell culture supernatant by ELISA. Additionally, membrane-bound protein expression was investigated by immunohistochemistry in situ. In septic ARDS, the distribution of ACE protein was significantly reduced in all lung endothelial cells (p<0.001). After stimulation with LPS, cultivated HPMEC showed more markedly than HUVEC, a concentration-dependent reduction of ACE protein expression compared to the respective untreated controls. Real-time PCR demonstrated a reduced ACE mRNA expression after LPS stimulation, predominantly in HPMEC. Specifically, in HPMEC, a concentration-dependent increase of shedded ACE was shown 24 h after LPS treatment. HPMEC cultures are an apt model for the investigation of pulmonary ACE expression in sepsis. This study suggests that reduced pulmonary microvascular endothelial ACE expression in septic ARDS is caused by two processes: (initial) increased shedding of ACE accompanied by a compensatory downregulation of ACE-mRNA and membrane-bound protein expression.

Abstract
PURPOSE In the face of improved radiological and arthroscopic techniques the diagnosis and treatment of SLAP lesions has recently gained much interest. Originally described as an (isolated) injury of the overhead athlete, it was only recently that the association of SLAP and rotator cuff defects was described in up to 40 % of cases. This study addresses the question of the evidence-based treatment of such frequent, combined lesions. METHODS Based on a systematic review of the online databases PubMed, EMBASE, CINAHL and Cochrane Library we identified clinical studies on the treatment of combined SLAP and rotator cuff lesions. Study quality was assessed using levels of evidence and a modified Jadad score. Clinical outcome was assessed through scores and range of motion assessments. RESULTS We included 7 studies of 374 patients with a mean age of 53 ± 11 years followed for 35 ± 13 months. Combined lesions have a significant negative effect on isolated rotator cuff or SLAP repair. Patients older than 45 years of age had a significantly better clinical result after biceps tenotomy than SLAP repair with concomitant rotator cuff repair. Biceps tenotomy plus rotator cuff repair showed significantly better range of motion for flexion and rotation than SLAP plus rotator cuff repair. CONCLUSION The frequent combination of SLAP and rotator cuff injury should be considered during assessment and informed consent of shoulder patients. While young patients and isolated SLAP lesions show excellent clinical results after elective repair, combined lesions should be treated with biceps tenotomy and/or debridement plus rotator cuff repair in patients older than 45 years.

Abstract
Cystic abdominal structures in first trimester fetuses are rare. In order to elucidate the clinical significance of first trimester abdominal cysts, we present three cases of the ultrasonographic detection of upper abdominal cysts in first trimester fetuses with spontaneous regression until birth. Cysts with maximum diameters of 20, 15 and 21 mm were diagnosed in the first scan at 12 + 3 weeks of gestation and two times at 13 + 0 weeks of gestation, respectively. They had echogenic walls, a longish shape and were all located in the upper part of the abdomen. Further anomalies, relevant maternal infections, the most frequent cystic fibrosis mutations and fetal chromosomal abnormalities were excluded. In all three cases follow-up scans showed similar characteristics: The relatively large intraabdominal cyst resolved during the early second trimester. A hyperdense structure of up to 24 mm close to the liver capsule was the sole prenatally detectable remnant. During the first months after birth, development of all three children was normal. Pediatric ultrasound examination reported subcapsular liver calcifications. In conclusion, these cases demonstrate that first trimester upper abdominal cysts with spontaneous resolution until birth are associated with a favorable outcome, if infections and additional anatomical or chromosomal anomalies are ruled out. Nevertheless, one should be aware that postnatal gastrointestinal complications have been described in a few cases, even if the cyst had resolved spontaneously in utero.

Abstract
We report the synthesis and characterization of novel mixed-metal binuclear ruthenium(II)-cobalt(II) photocatalysts for hydrogen evolution in acidic acetonitrile. First, 2-(2'-pyridyl)benzothiazole (pbt), 1, was reacted with RuCl(3)·xH(2)O to produce [Ru(pbt)(2)Cl(2)]·0.25CH(3)COCH(3), 2, which was then reacted with 1,10-phenanthroline-5,6-dione (phendione), 3, in order to produce [Ru(pbt)(2)(phendione)](PF(6))(2)·4H(2)O, 4. Compound 4 was then reacted with 4-pyridinecarboxaldehyde in order to produce [Ru(pbt)(2)(L-pyr)](PF(6))(2)·9.5H(2)O, 5 (where L-pyr = (4-pyridine)oxazolo[4,5-f]phenanthroline). Compound 5 was then reacted with [Co(dmgBF(2))(2)(H(2)O)(2)] (where dmgBF(2) = difluoroboryldimethylglyoximato) in order to produce the mixed-metal binuclear complex, [Ru(pbt)(2)(L-pyr)Co(dmgBF(2))(2)(H(2)O)](PF(6))(2)·11H(2)O·1.5CH(3)COCH(3), 6. [Ru(Me(2)bpy)(2)(L-pyr)Co(dmgBF(2))(2)(OH(2))](PF(6))(2), 7 (where Me(2)bpy = 1,10-phenanthroline, 4,4'-dimethyl-2,2'-bipyridine) and [Ru(phen)(2)(L-pyr)Co(dmgBF(2))(2)(OH(2))](PF(6))(2), 8 were also synthesised. All complexes were characterized by elemental analysis, ESI MS, HRMS, UV-visible absorption, (11)B, (19)F, and (59)Co NMR, ESR spectroscopy, and cyclic voltammetry, where appropriate. Photocatalytic studies carried out in acidified acetonitrile demonstrated constant hydrogen generation longer than a 42 hour period as detected by gas chromatography. Time resolved spectroscopic measurements were performed on compound 6, which proved an intramolecular electron transfer from an excited Ru(II) metal centre to the Co(II) metal centre via the bridging L-pyr ligand. This resulted in the formation of a cobalt(I)-containing species that is essential for the production of H(2) gas in the presence of H(+) ions. A proposed mechanism for the generation of hydrogen is presented.

Abstract
OBJECTIVE The objective of this systematic review was to assess cell/biomaterial treatments of degenerative disc disease in controlled animal trails. The primary endpoints were restoration of disc height and T2 signal intensity. METHOD PubMed, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and Cochrane Database of Systematic Reviews (CDSR) were searched for studies reporting on the use of tissue engineering treatments (cells/biomaterials/cells and biomaterials) for degenerative disc disease treatments in a controlled trial. Publication bias was assessed graphically using funnel plots and Egger's regression. Data were grouped by follow-up duration - early (<4 weeks), intermediate (4-12 weeks) and late (>12 weeks), and weighted mean differences (WMD) were calculated using DerSimonian-Laird Random Effect models. RESULTS Thirteen papers, published between 2004 and 2011, were included in this study. In comparison with the injured disc, all three treatments showed a positive effect in disc height, but none of the treatments restored disc height compared to the healthy disc. Overall, there seemed to be a better effect on disc height restoration for the treatment with cells and biomaterials. None of the treatments could achieve the same T2 signal intensity as the healthy disc, and compared to the injured disc, only the treatment with cells and biomaterials showed consistently better results. CONCLUSION Treatment of an injured/degenerating disc with cells, cells plus biomaterial or biomaterial alone has a potential for at least a partial regeneration of the disc. However, so far, none of the treatments is able to effectively restore the properties of a healthy disc.

Abstract
The excited state dynamics in polycrystalline thin films of tetracene are studied using both picosecond fluorescence and femtosecond transient absorption. The solid-state results are compared with those obtained for monomeric tetracene in dilute solution. The room temperature solid-state fluorescence decays are consistent with earlier models that take into account exciton-exciton annihilation and exciton fission but with a reduced delayed fluorescence lifetime, ranging from 20-100 ns as opposed to 2 μs or longer in single crystals. Femtosecond transient absorption measurements on the monomer in solution reveal several excited state absorption features that overlap the ground state bleach and stimulated emission signals. On longer timescales, the initially excited singlet state completely decays due to intersystem crossing, and the triplet state absorption superimposed on the bleach is observed, consistent with earlier flash photolysis experiments. In the solid-state, the transient absorption dynamics are dominated by a negative stimulated emission signal, decaying with a 9.2 ps time constant. The enhanced bleach and stimulated emission signals in the solid are attributed to a superradiant, delocalized S(1) state that rapidly fissions into triplets and can also generate a second superradiant state, most likely a crystal defect, that dominates the picosecond luminescence signal. The enhanced absorption strength of the S(0)→S(1) transition, along with the partially oriented nature of our polycrystalline films, obscures the weaker T(1)→T(N) absorption features. To confirm that triplets are the major species produced by relaxation of the initially excited state, the delayed fluorescence and ground state bleach recovery are compared. Their identical decays are consistent with triplet diffusion and recombination at trapping or defect sites. The results show that complications like exciton delocalization, the presence of luminescent defect sites, and crystallite orientation must be taken into account to fully describe the photophysical behavior of tetracene thin films. The experimental results are consistent with the traditional picture that tetracene's photodynamics are dominated by exciton fission and triplet recombination, but suggest that fission occurs within 10 ps, much more rapidly than previously believed.

Abstract
Expression of the AF4-MLL fusion protein in murine hematopoietic progenitor/stem cells results in the development of proB acute lymphoblastic leukemia. In this study, we affinity purified the AF4-MLL and AF4 protein complexes to elucidate their function. We observed that the AF4 complex consists of 11 binding partners and exhibits positive transcription elongation factor b (P-TEFb)-mediated activation of promoter-arrested RNA polymerase (pol) II in conjunction with several chromatin-modifying activities. In contrast, the AF4-MLL complex consists of at least 16 constituents including P-TEFb kinase, H3K4(me3) and H3K79(me3) histone methyltransferases (HMT), a protein arginine N-methyltransferase and a histone acetyltransferase. These findings suggest that the AF4-MLL protein disturbs the fine-tuned activation cycle of promoter-arrested RNA Pol II and causes altered histone methylation signatures. Thus, we propose that these two processes are key to trigger cellular reprogramming that leads to the onset of acute leukemia.

Abstract
BACKGROUND Quantifying the histopathological diagnoses of appendectomies in daily routine paidopathology results in a high percentage of appendices without histomorphological sign of acute inflammation. To identify clinical factors significantly associated with the morphological diagnosis, histopathological findings and clinical data--documented in patients' files--were examined. PATIENTS All 856 children (age: 5 m-15 yrs) whose appendix had been resected within a 7-year-period were--depending on the histopathological diagnoses--allocated to the group "appendix without" resp. "appendix with signs of acute inflammation". METHOD All files were examined concerning anamnestic data, clinical signs of acute appendicitis and laboratory parameters. The data were analysed by χ(2)-test and Wilcoxon-test concerning differences between the 2 groups with regard to the anamnestic and clinical facts and parameters. Using binary logistic regression, these clinical parameters were analyzed in correlation with the histopathological diagnoses. RESULTS By consideration of the factors "leucocyte count", "vomiting" and "percussion tenderness" 75% of the children would have been allocated to the accurate postoperative pathomorphological diagnosis. CONCLUSIONS There was a significant correlation of "leucocyte count", "vomiting" and "percussion tenderness" with histopathology in 75% of the children. As hence 25% were not allocated correctly this combination is no unequivocal combination for prediction or exclusion of an acute appendicitis. Hence, even with these statistically significant parameters a comparably high percentage of falsely-positive appendectomies has to be anticipated.

Abstract
OBJECTIVE Information on the evaluation of prenatal ocular findings is sparse. This article provides an overview of the morphology in a cohort of human fetal eyes, with particular emphasis on interesting findings. METHODS The study investigated 216 eyes from 115 human fetuses. RESULTS The majority of fetal eyes presented with a regular phenotype. Rarely, unexpected findings were discovered in fetuses with or without systemic malformations. CONCLUSION Routine evaluation of fetal eyes reveals-albeit rarely-new aspects providing further knowledge and occasionally enabling the exact classification of syndromes.

Abstract
BACKGROUND More than 90% of pediatric renal tumors are nephroblastomas while renal cell carcinomas (RCC) are rare in children (< 5%). PATIENT According to the clinical diagnoses of a nephroblastoma stage IV a 7-year-old boy with a kidney tumor and peripheral pulmonary lesion was preoperatively treated for 8 weeks with Vincristine, Actinomycin D and Adriamycin. The resected kidney displayed a RCC with Xp11.2 translocation. There was no tumor regression and the pulmonary lesion was no longer detectable. Hence chemotherapy was put to a halt. CONCLUSION Fine needle aspiration biopsy (FNA) would have allowed to adjust the tumor subtype. Prognosis of pediatric RCC with translocation seems more favourable than without translocation though definitive evidence will only be possible by documentation in a clinical diagnose-related register.

Abstract
Grafts generated by cultivation of progenitor cells from the stromal vascular fraction of human adipose tissue have been proven to have osteogenic and vasculogenic properties in vivo. However, in vitro manufacture of such implants is challenged by complex, impractical and expensive processes, and requires implantation in a separate surgery. This study investigates the feasibility of an intraoperative approach to engineer cell-based bone grafts with tissue harvest, cell isolation, cell seeding onto a scaffold and subsequent implantation within a few hours. Freshly isolated adipose tissue cells from a total of 11 donors, containing variable fractions of mesenchymal and endothelial progenitors, were embedded at different densities in a fibrin hydrogel, which was wrapped around bone substitute materials based on beta-tricalcium phosphate (ChronOS), hydroxyapatite (Engipore), or acellular xenograft (Bio-Oss). The resulting constructs, generated within 3 hours from biopsy harvest, were immediately implanted ectopically in nude mice and analysed after eight weeks. All explants contained blood vessels formed by human endothelial cells, functionally connected to the recipient's vasculature. Human origin cells were also found within osteoid structures, positively immunostained for bone sialoprotein and osteocalcin. However, even with the highest loaded cell densities, no frank bone tissue was detected, independently of the material used. These results provide a proof-of-principle that an intraoperative engineering of autologous cell-based vasculogenic bone substitutes is feasible, but highlight that - in the absence of in vitro commitment--additional cues (e.g., low dose of osteogenic factors or orthotopic environmental conditions) are likely needed to support complete osteoblastic cell differentiation and bone tissue generation.

Abstract
OBJECTIVE Upstream transcription factor 1 (USF1) regulates genes of glucose and lipid metabolism. Polymorphisms in the USF1 gene showed association with familial combined hyperlipidemia and lipid parameters. The aim of our study was to examine the associations between USF1 polymorphisms and lipid parameters as well as incident type 2 diabetes mellitus (T2DM) in German Caucasians. DESIGN We genotyped eight polymorphisms in the USF1 gene in 2067 middle-aged (35-74 years) individuals including 498 incident T2DM cases and 1569 non-cases of the population-based case-cohort study from the MONICA/KORA Augsburg project. METHODS Six polymorphisms and their haplotypes were analyzed using multivariable linear regression and Cox proportional hazards models. RESULTS Polymorphism rs3737787 was inversely associated with incident T2DM in women with decreased risk for female heterozygotes compared with women homozygous for the major allele (Hazard ratio=0.57; 95% confidence intervals: 0.38-0.87; P=0.008). After correction for multiple testing, significance remained. Polymorphisms rs3813609 and rs1556259 were significantly associated with reduction in low-density lipoprotein (LDL) cholesterol (p(NOM)=0.001; p(NOM)=0.00002) in women. Analyses also indicated associations of haplotypes with LDL cholesterol in women, but the association lost statistical significance after correction for multiple testing. Total serum cholesterol (TC) and high-density lipoprotein (HDL) cholesterol were weakly associated (P<0.05) with USF1 polymorphisms in women. No significant associations were found in men. CONCLUSIONS In this large population-based study, statistically significant associations of USF1 polymorphisms with incident T2DM and LDL cholesterol were found in women, but not in men. Genetic variants in the USF1 gene showed weak or no associations with TC and HDL cholesterol.
