Abstract
BACKGROUND AND AIMS Falls are a significant cause of mortality in the elderly patients. Despite this, the literature on in-hospital mortality related to elderly falls remains sparse. Our study aims to determine the risk factors associated with in-hospital mortality in elderly patients admitted to a regional trauma center after sustaining a fall. METHODS All elderly case records with fall-related injuries between 2003 and 2013 were retrospectively analyzed for demographic characteristics, injury severities, comorbidity factors and clinical outcomes. Logistic regression analysis was used to examine the risk factors associated with in-hospital mortality. RESULTS In total, 1026 elderly patients with fall-related injuries were included in the study. The average age of patients was 80.94 ± 8.16 years. Seventy seven percent of the patients had at least one comorbid condition. Majority of the falls occurred at home. More than half of the patients fell from ground level. Overall, the in-hospital mortality rate was 16 %. Head injury constituted the most common injury sustained in patients who died (77 %). In addition to age, ISS, GCS, ICU admission and anemia were significantly (P < 0.05) associated with in-hospital deaths in elderly fall patients. CONCLUSION Ground-level falls in the elderly can be devastating and carry a significant mortality rate. Elderly patients with anemia were two times more likely to die in the hospital after sustaining a fall in our study population. Increased focus on anemia which is often underappreciated in elderly fall patients can be beneficial in improving outcomes and reducing in-hospital mortality.

Abstract
Neuroinflammatory disturbances have been closely associated with depression and many other neuropsychiatric diseases. Although targeting neuroinflammatory mediators with centrally acting drugs has shown certain promise, its translation is faced with several challenges especially drug delivery and safety concerns. Here, we report that neuroinflammation-induced behavioral abnormality could be effectively attenuated with immunomodulatory agents that need not to gain brain penetration. In a rat model with intracerebral lipopolysaccharide (LPS) challenge, we validated that ginsenoside Rg1 (Rg1), a well-established anti-inflammatory agent, was unable to produce a direct action in the brain. Interestingly, peripherally restricted Rg1 could effectively attenuate the weight loss, anorexic- and depressive-like behavior as well as neurochemical disturbances associated with central LPS challenge. Biochemical assay of neuroimmune mediators in the periphery revealed that Rg1 could mitigate the deregulation of the hypothalamic-pituitary-adrenal axis and selectively blunt the increase in circulating interleukin-6 levels. Furthermore, these peripheral regulatory effects were accompanied by dampened microglial activation, mitigated expression of pro-inflammatory mediators and neurotoxic species in the central compartment. Taken together, our work suggested that targeting the peripheral immune system may serve as a novel therapeutic approach to neuroinflammation-induced neuropsychiatric disorders. Moreover, our findings provided the rationale for employing peripherally active agents like Rg1 to combat mental disturbances.

Abstract
This study aimed to quantify and compare the prevalence of simple prescribing errors made by clinicians in the first 24 hours of a general medical patient's hospital admission. Four public or private acute care hospitals across Australia and New Zealand each audited 200 patients' drug charts. Patient demographics, pharmacist review and pre-defined prescribing errors were recorded. At least one simple error was present on the medication charts of 672/715 patients, with a linear relationship between the number of medications prescribed and the number of errors (r = 0.571, p < 0.001). The four sites differed significantly in the prevalence of different types of simple prescribing errors. Pharmacists were more likely to review patients aged > or = 75 years (39.9% vs 26.0%; p < 0.001) and those with more than 10 drug prescriptions (39.4% vs 25.7%; p < 0.001). Patients reviewed by a pharmacist were less likely to have inadequate documentation of allergies (13.5% vs 29.4%, p < 0.001). Simple prescribing errors are common, although their nature differs from site to site. Clinical pharmacists target patients with the most complex health situations, and their involvement leads to improved documentation.

Abstract
PURPOSE The detection of fetal structural abnormalities is a routine part of antenatal care. Ultrasound examination policies vary among European countries. An additional ultrasound for fetal structural anomalies in the 3 rd trimester seems important for many reasons. Some abnormalities develop or first become apparent later in pregnancy. The aim of the study was to analyze the rate of previously undetected structural abnormalities in the 3 rd trimester. MATERIALS AND METHODS 8074 fetuses were examined in this prospective study between 1998 and 2008. All received an examination at 11 - 14 weeks and 79 % (6378 / 8074) of these fetuses also received an ultrasound at 20 - 24 weeks. If both of the examinations did not detect structural abnormalities, the fetuses were included in the study group and received an ultrasound at 28 - 32 weeks (n = 5044). New structural abnormalities in the 3 rd trimester were analyzed. The outcome was available in 96 % of the cases. RESULTS The overall incidence of fetal malformations was 3.6 % (n = 289), of which 40 % (116 / 289) were diagnosed at 11 - 14 weeks. The following 2nd trimester scan revealed 102 (35 %) new fetal malformations. An additional 44 (15 %) structural abnormalities were found in the 3 rd trimester. These were mainly abnormalities of the urogenital system (n = 18). There were also anomalies of the cardiovascular system (n = 9), the gastrointestinal system (n = 6) and the central nervous system (n = 4). One of the cases had a previously undiagnosed abnormal karyotype. CONCLUSION The ultrasound examination in the 3 rd trimester is of additional benefit and can detect previously unknown structural abnormalities. These findings are relevant for perinatal management and postnatal follow-up.

Abstract
Collagen-induced arthritis (CIA) is an experimental autoimmune disease that can be elicited in susceptible strains of rodents (rat and mouse) and nonhuman primates by immunization with type II collagen (CII), the major constituent protein of articular cartilage. Because of the important similarities between CIA and rheumatoid arthritis, this experimental model of autoimmune arthritis has been the subject of extensive investigation in several laboratories. Protocols for CIA are described in this unit for both the mouse model and the rat model. In addition, protocols are included for the purification of CII from bovine articular joints and chicken sternums, for the purification of collagen a1(II) chains, and for the purification of fragments of these chains following cyanogen bromide (CNBr) digestion. The preparation of CII is a time-consuming procedure but is usually required because of the scarcity and expense of commercial sources of purified native CII. In addition, support protocols are provided for assessing the severity of inflammation following CIA and for measuring B and T cell responses to CII.

Abstract
Diastematomyelia is a rare form of occult spinal dysraphism. It is characterized by longitudinal clefting and separating of the spinal cord by a bony or fibrous spur. Diastematomyelia is associated with other anomalies, i. e. spina bifida, scoliosis, visceral malformations or anomalies of the overlying skin. Prenatal diagnosis is based on fetal ultrasound supplemented by fetal MRI. We present a case of diastematomyelia and prenatal diagnosis in the 23rd gestational week using routine ultrasound scanning and confirmation by fetal MRI. After vaginal delivery at term, the child's development is normal. Prenatal diagnosis of isolated diastematomyelia is challenging. Management and prognosis are still controversial as only few cases have been reported. Affected fetuses might benefit from early diagnosis enabling surgical intervention before the development of neurological sequelae.

Abstract
10608 Background: The transforming growth factor-β (TGF-β) has a dual role in cancer, but in the prevention of tumorigenesis, TGF-β signaling inhibits cell cycle progression through an increase in cell cycle inhibitors and decrease in cell cycle activators. The adaptor protein embryonic liver fodrin (ELF) is crucial for normal TGF-β signaling. ELF facilitates the association and nuclear translocation of the TGF-β signaling proteins, Smad3 and Smad4. We have demonstrated that elf± mice develop hepatocellular cancers (HCC) spontaneously within 12 months. We have also shown that most human HCCs demonstrate a decreased expression of ELF. Our goal was to assess the interaction between ELF and cyclin dependent kinase 4 (CDK4), which is overexpressed in most human cancers. Methods: We compared the expression of CDK4 and ELF by immunohistochemistry and analyzed the interaction between CDK4 and ELF, in vitro by immunoprecitpitation and western blot. Finally, we assessed the development of HCC in intercrossed elf± and CDK4+/neo mice. Results: CDK4 and ELF expression are inversely correlated in HCCs from elf± mice. Furthermore, ELF interacts with CDK4 by forming a complex that includes Smad3 in COS-7 and HepG2 cells. ELF is phosphorylated upon overexpression of CDK4, revealing a possible mechanism by which CDK4 may inhibit ELF-dependent TGF-β signaling. To further assess whether the development of HCC in elf± mice is dependent upon CDK4 expression, we have intercrossed elf± and CDK4+/neo mice. At 12 months, only 17% of the elf±/CDK4+/neo mice developed HCC, compared to 40% of our historical control elf± mice. This initial data strongly suggests that haploinsufficiency of CDK4 can prevent the HCCs seen in elf± mice, and provides the genetic foundation for further exploring the benefits of specific inhibitors of CDK4 in the treatment of HCC. Conclusions: These results demonstrate the molecular interactions between ELF and CDK4, and suggest a mechanism by which CDK4 may render cells unresponsive to the growth inhibitory effects of TGF-β signaling. Furthermore, haploinsufficiency of CDK4 prevents the formation of HCC, and thus targeted-inhibition of CDK4 activity may be a logical treatment for HCC in humans. No significant financial relationships to disclose.

Abstract
The genome sequence of the genetically tractable, mesophilic, hydrogenotrophic methanogen Methanococcus maripaludis contains 1,722 protein-coding genes in a single circular chromosome of 1,661,137 bp. Of the protein-coding genes (open reading frames [ORFs]), 44% were assigned a function, 48% were conserved but had unknown or uncertain functions, and 7.5% (129 ORFs) were unique to M. maripaludis. Of the unique ORFs, 27 were confirmed to encode proteins by the mass spectrometric identification of unique peptides. Genes for most known functions and pathways were identified. For example, a full complement of hydrogenases and methanogenesis enzymes was identified, including eight selenocysteine-containing proteins, with each being paralogous to a cysteine-containing counterpart. At least 59 proteins were predicted to contain iron-sulfur centers, including ferredoxins, polyferredoxins, and subunits of enzymes with various redox functions. Unusual features included the absence of a Cdc6 homolog, implying a variation in replication initiation, and the presence of a bacterial-like RNase HI as well as an RNase HII typical of the Archaea. The presence of alanine dehydrogenase and alanine racemase, which are uniquely present among the Archaea, explained the ability of the organism to use L- and D-alanine as nitrogen sources. Features that contrasted with the related organism Methanocaldococcus jannaschii included the absence of inteins, even though close homologs of most intein-containing proteins were encoded. Although two-thirds of the ORFs had their highest Blastp hits in Methanocaldococcus jannaschii, lateral gene transfer or gene loss has apparently resulted in genes, which are often clustered, with top Blastp hits in more distantly related groups.

Abstract
Elevations in the concentration of cell-free fetal DNA in maternal plasma have recently been determined in various pregnancy-related disorders, including preeclampsia, preterm labor, and polyhydramnios. In addition, almost 2-fold increments in cell-free fetal DNA levels have been recorded in pregnancies with certain aneuploid fetuses, in particular trisomy 21. These findings have led to the speculation that quantitative assessment of circulatory fetal DNA may be useful in the noninvasive prenatal diagnosis of certain fetal genetic constellations or pregnancy-related disorders. A premise for any quantitative analysis is that the quantity of the analyte being assayed does not vary greatly over time. As this aspect has not been examined for circulatory DNA levels, we examined these in normal healthy individuals as well as in pregnant women. Our data indicate that severalfold alterations in circulatory DNA amounts do occur over short periods of time. Of particular note is that we observed almost 2-fold variations in free fetal DNA levels over a period of 3 days, which are in a similar range to the elevations noted in aneuploid pregnancies. Our results, therefore, imply that caution should be used when using small increments in circulatory fetal DNA concentrations for potential diagnostic applications.

Abstract
Gastrointestinal (GI) tract damage by chemotherapy or radiation limits their efficacy in cancer treatment. Radiation has been postulated to target epithelial stem cells within the crypts of Lieberkühn to initiate the lethal GI syndrome. Here, we show in mouse models that microvascular endothelial apoptosis is the primary lesion leading to stem cell dysfunction. Radiation-induced crypt damage, organ failure, and death from the GI syndrome were prevented when endothelial apoptosis was inhibited pharmacologically by intravenous basic fibroblast growth factor (bFGF) or genetically by deletion of the acid sphingomyelinase gene. Endothelial, but not crypt, cells express FGF receptor transcripts, suggesting that the endothelial lesion occurs before crypt stem cell damage in the evolution of the GI syndrome. This study provides a basis for new approaches to prevent radiation damage to the bowel.

Abstract
How allelic diversity affects neural mechanisms to produce behavioral variation is largely unknown. The elevated plus maze, consisting of open and closed arms, has been used as a model of behavioral variation in rodent exploration. Under dim illumination the nature of the sensory stimuli that influence arm choice is uncertain. Two inbred mouse strains, A/J (Tyrc/Tyrc, the albino phenotype, mutation in tyrosinase) with a strong preference for closed arm entry, and CBA/J (Pdebrdl/Pdebrdl, the retinal degeneration phenotype, mutation in the beta-subunit of rod cGMP phosphodiesterase), with a weak preference for open arm entry, were studied under varying light. Because behavioral differences persist under red light, variation in light perception is not likely to fully account for variation in arm choice. To identify genetic factors influencing arm choice (100 x Open arm entries/Total arm entries) quantitative trait loci analyses (QTL) were performed on (A/J x CBA/J)F2 mice. Two QTLs, one of which includes PDEB, were identified on Chr 5 (LOD > 10) and account for > 30% of the behavioral variation in arm preference. Tyr (Chr 7, 44 cM) was linked to closed arm entries but not arm preference, and is unlikely to be acting through a direct effect on light perception, because A/J arm entries were not affected by red light and there was no interaction with PDEB in the (A/J x CBA/J)F2 mice. Whether the candidate QTLs on Chr 5 affect arm choice through an effect on light perception is unknown, but phenotypic differences between F2 mice with retinal degeneration and CBA/J mice and F2 mice with albinism and A/J mice suggest that factors other than light sensitivity contribute to arm preference in these two strains.

Abstract
OBJECTIVE To examine whether concentrations of free extracellular fetal circulatory DNA in maternal plasma are stable or fluctuate. METHODS Consecutive blood samples were drawn from 13 healthy nonpregnant volunteers and from 16 healthy pregnant women over 3 days. DNA was isolated from the plasma fraction and quantified by real-time polymerase chain reaction (PCR). RESULTS In nonpregnant controls the total amount of cell free DNA fluctuated by an average of 13.5-fold. In samples obtained from pregnant women the amount of maternal cell free DNA varied by an average of 21.5-fold. Because ten of those women were pregnant with male fetuses, the concentration of free fetal DNA in these cases was determined by a real-time PCR assay for the Y chromosome. The mean variation in free fetal DNA levels in male fetuses was 2.2-fold. CONCLUSION The degree of variation in free fetal DNA concentrations observed in this study was similar to published values, so these results imply that care should be exercised when considering quantitation of this fetal material for potential diagnostic or screening purposes.

Abstract
The first report of the occurrence of fetal cells in maternal circulation dates back to 1893 when the German pathologist Schmorl identified trophoblast cells in the lungs of women who had died from eclampsia. Till recently, however, the existence of fetal cells in maternal blood was a matter of considerable debate. The main reason for this dispute was the inability to successfully and reliably enrich for these cells, which has also hindered their clinical use. In the meantime, this issue has been addressed and the both fetal aneuploidies and single gene defects can now be detected in a non-invasive manner using fetal cells enriched from maternal blood.
