Abstract
Sixty-nine isolates obtained during the manufacture and ripening of Spanish fermented sausages were identified to species level using the Vitek Bacillus biochemical card, the dichotomous key and table proposed by Berkeley et al. ((1984). In Methods in Microbiology, Vol. 16. Academic Press, London, p. 291), morphological and physiological tests and the API 20E miniaturized system. None of the tested systems was entirely satisfactory and the final identification was mainly done on the basis of cellular morphology and the table of test results. Our isolates belonged to the species: B. subtilis (37), B. megaterium (22), B. pumilus (5), B. circulans (3) and unidentified (2). Forty-five cultures (65.2%) were accurately identified with the dichotomous key. A similar figure for the Vitek Bacillus biochemical card was 36%. The results of the API 20E system were very reproducible, especially those of the Voges-Proskauer test. Most of the strains of B. megaterium were misidentified as B. subtilis with the dichotomous key. On the other hand, a high percentage of the cultures belonging to B. subtilis were misidentified as B. megaterium with the Vitek system.

Abstract
AIMS/HYPOTHESIS A leading cause of type 2 diabetes is a reduction in functional beta cell mass partly due to increased beta cell death, triggered by stressors such as glucolipotoxicity (GLT). This study evaluates the hypothesis that lactogens can protect beta cells against GLT and examines the mechanism behind the pro-survival effect. METHODS The effect of exogenous treatment or endogenous expression of lactogens on GLT-induced beta cell death was examined in INS-1 cells, and in rodent and human islets. The mechanism behind the pro-survival effect of lactogens was determined using an inhibitor, siRNAs, a dominant negative (DN) mutant, and Cre-lox-mediated gene deletion analysis. RESULTS Lactogens significantly protect INS-1 and primary rodent beta cells against GLT-induced cell death. The pro-survival effect of lactogens in rodent beta cells is mediated through activation of the Janus kinase-2 (JAK2)/signal transducer and activator of transcription-5 (STAT5) signalling pathway. Lactogen-induced increase in the anti-apoptotic B cell lymphoma-extra large (BCLXL) protein is required to mediate its pro-survival effects in both INS-1 cells and primary rodent beta cells. Most importantly, lactogens significantly protect human beta cells against GLT-induced cell death, and their pro-survival effect is also mediated through the JAK2/STAT5 pathway. CONCLUSIONS/INTERPRETATION These studies, together with previous work, clearly demonstrate the pro-survival nature of lactogens and identify the JAK2/STAT5 pathway as an important mediator of this effect in both rodent and human beta cells. Future studies will determine the effectiveness of this peptide in vivo in the pathophysiology of type 2 diabetes.

Abstract
OBJECTIVES To examine the prognostic value of different profiles of hip fracture patients for recovery of pre-fracture functional level and for post-fracture mortality. DESIGN Observational, longitudinal study. SETTING University hospital. PARTICIPANTS Five hundred and eight patients who received surgery for hip fracture and were followed for 24 months post-fracture. MEASUMENTS: Patients were assessed according to age, number of independent activities of daily living (ADLs) and dementia. The probability of recovery of previous ambulation level and mortality was established at 3, 6, 12 and 24 months post-fracture. Patients were first classified according to the seven different profiles previously established by Penrod. A new patient classification system was then created using different patient groups: persons aged 75 or older were first classified based on the number of independent ADLs they could perform (4, 3-2 and 1-0) and were then subdivided according to age (75-84 years and >84 years) and presence of dementia. RESULTS Mean age was 84.5 (SD 6.3) years. Almost all (90.6%) patients walked independently before the fracture. At 24 months' follow-up, the probability of recovery to previous level of ambulation was 73.6%. The new classification into seven groups had higher prognostic value than Penrod's system. Patients under 75 had 95.1% probability of functional recovery and 9.6% of dying. At the other extreme, those over 84 years with 0-1 independent activities of daily living and dementia had 23.9% probability of recovery and 71.4% of dying. CONCLUSION Hip fracture patients can be classified into homogeneous groups with different prognostic profiles based on pre-fracture characteristics. This new classification improves Penrod's previous system by establishing groups of patients hierarchically ordered by the probability of recovery and mortality at 3, 6, 12 and 24 months post-fracture.

Systemic and acute administration of parathyroid hormone-related peptide(1-36) stimulates endogenous beta cell proliferation while preserving function in adult mice. Diabetologia 2011; 54:2867-77.

Abstract
AIMS/HYPOTHESIS A major focus in the treatment of diabetes is to identify factors that stimulate endogenous beta cell growth while preserving function. The first 36 amino acids of parathyroid hormone-related protein (PTHrP) are sufficient to enhance proliferation and function in rodent and human beta cells in vitro. This study examined whether acute and systemic administration of the amino-terminal PTHrP(1-36) peptide can achieve similar effects in rodent beta cells in vivo. METHODS Adult male mice were injected with 40, 80 or 160 μg of PTHrP(1-36) per kg body weight or with vehicle for 25 days. Glucose and beta cell homeostasis, as well as expression of differentiation markers and cell cycle genes were analysed. RESULTS All three doses of PTHrP(1-36) significantly enhanced beta cell proliferation in vivo at day 25, with 160 μg/kg PTHrP(1-36) increasing proliferation as early as day 5. Importantly, the two higher doses of PTHrP(1-36) caused a significant 30% expansion of beta cell mass, with a short-term improvement in glucose tolerance. PTHrP(1-36) did not cause hypercalcaemia, or change islet number, beta cell size, beta cell death or expression of differentiation markers. Analysis of islet G1/S cell cycle proteins revealed that chronic overabundance of PTHrP(1-139) in the beta cell significantly increased the cell cycle activator cyclin D2 and decreased levels of cyclin-dependent kinase 4 inhibitor (p16( Ink4a ) [Ink4a also known as Cdkn2a]), but acute treatment with PTHrP(1-36) did not. CONCLUSIONS/INTERPRETATION Acute and systemic administration of PTHrP(1-36) increases rodent beta cell proliferation and mass without negatively affecting function or survival. These findings highlight the future potential therapeutic effectiveness of this peptide under diabetes-related pathophysiological conditions.

Abstract
SUMMARY In this study 509 hip fracture patients were followed-up during 24 months measuring their recuperation in activities of daily living. The different activities measured had both different profile and probability of recovery. INTRODUCTION Recovery of pre-fracture functional level is a goal of hip fracture treatment. The objective of this study was to measure recovery of previous functional level for ambulation and for the activities of daily living during the 24 months after osteoporotic hip fracture. METHODS This is a longitudinal prospective study of the patients admitted to the orthopaedics department of a university hospital for hip fracture and followed up by a geriatrician during three years (2003-2005). Demographic, clinical, functional and treatment data were collected during hospitalisation. Telephone follow-up was made at 3, 6, 12 and 24 months. Data were analysed by survival analysis applying the Kaplan-Meier estimator. RESULTS Five hundred and nine patients were included. The mean age was 84.5 (SD 6.3) years. The activities with lower probability of recovery to the previous level at 24 months were climbing stairs, chair/bed transfers, ambulation, dressing, bathing and use of toilet (between 67.5% and 76% recovery). The activities with higher probability of recovery were grooming, feeding and bladder and bowel control (between 86.3% and 95.4%). Recovery of previous performance level for ambulation, chair/bed transfers, use of toilet, feeding, grooming and bladder control occurred primarily during the first 6 months, whereas recovery of bathing, dressing and climbing stairs occurred mainly in the first 12 months after the fracture. CONCLUSIONS The activities with lower likelihood of recovery were ambulation, chair/bed transfers, climbing stairs, use of toilet, bathing and dressing. Time of recovery varied by activity; bathing, dressing and climbing stairs were the activities with the longest recovery time.

Abstract
The reaction of phosphanido complexes [Nb(η(5)-C(5)H(4)SiMe(3))(2)(L)(PPh(2))] [L = CO (1), CNXylyl (2)] with early transition metal halides in high oxidation states has been carried out. New bimetallic niobocene complexes [{Nb(η(5)-C(5)H(4)SiMe(3))(2)(L)}(μ-PPh(2))(MCl(5))] [M = Nb, L = CO (3), L = CNXylyl (4); M = Ta, L = CO (5), L = CNXylyl (6)] have been successfully synthesized by the reaction with [MCl(5)](2) (M = Nb or Ta). In a similar way [{Nb(η(5)-C(5)H(4)SiMe(3))(2)(L)}(μ-PPh(2))(MCl(4))] [M = Ti, L = CO (13), CNXylyl (14); M = Zr, L = CO (15), CNXylyl (16)] were synthesized using MCl(4) (M = Ti or Zr). Solutions of complexes 4-6 in chloroform produced new ionic derivatives [Nb(η(5)-C(5)H(4)SiMe(3))(2)(P(H)Ph(2))(L)] [MCl(6)] [M = Nb, L = CO (7), L = CNXylyl (8); M = Ta, L = CO (9), L = CNXylyl (10)]. Ionic complexes [Nb(η(5)-C(5)H(4)SiMe(3))(2)(P(Cl)Ph(2))(L)] [NbCl(4)O(thf)] [L = CO (11), CNXylyl (12)] were formed from solutions in thf - rapidly in the case of 3 but more slowly for 4. New heterometallic complexes [Nb(η(5)-C(5)H(4)SiMe(3))(2)(L)(μ-PPh(2)){(Ti(η(5)-C(5)R(5))Cl(3)}] [R = H, L = CO (17), CNXylyl (18); R = CH(3), L = CO (19), CNXylyl (20)] were synthesized by the reaction of 1 or 2 with [Ti(η(5)-C(5)R(5))Cl(3)] (R = H or CH(3)). All of these compounds were characterized by IR and multinuclear NMR spectroscopy, and the molecular structures of 9 and 12 were determined by single-crystal X-ray diffraction.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most frequent types of tumor. The aim of this study was to determine the survival of patients who had received liver transplants as a result of the disease. METHODS This observational follow-up study included 150 patients who received liver transplantations from June 1994 to December 2007. The study considered epidemiological and staging variables, tumor descriptions, and follow-up variables. We employed Kaplan-Meier methodology together with a Cox multivariate regression analysis. RESULTS The incidence of tumor relapse was 13.3%, with survival rates at 1, 3, and 5 years of 89.3%, 73.1%, and 61.4%, respectively. Variables that showed an independent effect to predict mortality were the degree of histological differentiation and of macrovascular invasion. Patients with poorly differentiated HCC had a 4.03 fold (95% confidence interval [CI]: 1.61-10.06) greater possibility of dying. Macrovascular involvement increased the risk of death (relative risk = 2.23), an effect that was at the limit of significance (95% CI 0.99-5.04). CONCLUSIONS The survival rate was consistent with the literature. Poor tumor differentiation and macrovascular involvement were independent predictors of mortality.

Abstract
OBJECTIVE To assess the effects of growth hormone (GH) treatment combined with cognitive rehabilitation in patients with adult growth hormone deficiency (GHD) and cognitive disorders occurring after traumatic brain injury (TBI). PARTICIPANTS Nineteen adult patients with TBI: GHD was found in 11 of them. INTERVENTION Patients were treated with GH (GHD; sc; 1 mg/day) or vehicle (controls; sc; 1 mg/day); daily cognitive rehabilitation therapy was performed in both groups for 3 months. MAIN OUTCOME MEASURES The GHRH-arginine test established GHD. The neuropsychological test WAIS was performed before commencing the treatment and 3 months after commencing it. RESULTS Controls achieved significant improvements in digits and in manipulative intelligence quotient (IQ) (p < 0.05 vs. baseline). GHD achieved significant improvements in more cognitive parameters: understanding, digits, numbers and incomplete figures (p < 0.05 vs. baseline) and similarities, vocabulary, verbal IQ, manipulative IQ and total IQ (p < 0.01). GHD reached significantly greater improvements than controls in similarities (p < 0.01) and in vocabulary, verbal IQ and total IQ (p < 0.05). CONCLUSION GH administration significantly improved cognitive rehabilitation in GHD patients. Since at the end of treatment period plasma IGF-I levels were similar in both groups it is likely that exogenous GH administration is responsible for the significant differences found.

Abstract
BACKGROUND Human enteroviruses (HEV) are the commonest cause of viral meningitis as well as other pathologies, therefore HEV characterization is important both in patient management and epidemiological investigation. OBJECTIVES A 10-year study of patients with enteroviral infection was carried out in Spain to determine the underlying etiology. STUDY DESIGN HEV were fully typed by microneutralisation tests and/or molecular methods. RESULTS A collection of 86404 clinical samples were studied in several Spanish laboratories. These were collected from patients with different syndromes, mainly aseptic meningitis (AM), fever, respiratory diseases and acute flaccid paralysis. Of these, 6867 HEV were obtained. At the National Poliovirus Laboratory 2814 were serotypically characterised. Among non-polio enteroviruses, the eight main serotypes were Echovirus 30 (25%), Echovirus 6 (12.4%), Echovirus 13 (8.3%), Echovirus 11 (7.4%) and Echovirus 9 (4.7%), followed by Coxsackievirus B5 (4.2%) and Echovirus 7 and Coxsackievirus A9 (3.7%) each. In AM cases, Echovirus 30 was identified in 39% of them, followed by Echovirus 6 (14%). However, Echovirus 6 was mainly associated with respiratory disease (17%), followed by Echovirus 11 (10%). On the other hand, Echovirus 30, Echovirus 11 and Echovirus 6 contributed equally with 12% of each serotype in the cases of fever. CONCLUSIONS The present report complements previous data (Trallero et al.(13)), with the results of HEV incidence in Spain from 1998 to 2007. The surveillance described in this study provided valuable information as to which serotypes are in circulation, the emergence of new HEV and association with clinical manifestations.

Abstract
BACKGROUND End-stage renal disease is a major health problem worldwide nowadays. Although conventional hemodialysis is the most widely used modality, short daily hemodialysis has been proposed as a more physiologic treatment. The objective of this article is to compare the quality of life of patients on each hemodialysis modality. METHODS A multicentric cross-sectional study was performed in 9 Spanish hospitals. Patients treated for at least 3 months with conventional or short daily hemodialysis were included and quality of life measured using the Euroqol-5D quality of life questionnaire. Bayesian models were used for analyzing quality of life results. RESULTS Ninety-three patients were included, 27 were on daily hemodialysis and 66 on conventional hemodialysis. All models demonstrated a better quality of life for daily hemodialysis versus conventional hemodialysis. Only 14% of the patients on conventional hemodialysis were willing to change to a daily schedule. CONCLUSIONS Short daily hemodialysis shows a better quality of life than conventional hemodialysis with all Bayesian approaches considered.

Abstract
Galicia's coast (northwestern Spain) is a major producer of bivalve molluscs. Over an 18-month period, the presence of Salmonella, Aeromonas, Plesiomonas shigelloides, Vibrio parahaemolyticus, and Clostridium botulinum was determined by PCR methods in mussels (22 batches) and infaunal bivalves (31 batches of clams and cockles) before and after depuration. All batches were harvested from Galician class B harvesting areas where bivalve molluscs must not exceed 4,600 Escherichia coli per 100 g of flesh and liquor in 90% of the samples. Virulence-associated genes of Salmonella (invA), Aeromonas (aerA, hlyA, alt, ast, and laf), P. shigelloides (hugA), V. parahaemolyticus (tdh and trh), and C. botulinum (BoNT) were not detected. The pR72H chromosomal DNA fragment, which is conservative in V. parahaemolyticus strains, was detected in five (4.7%) samples. A number of 192 suspect isolates did not fit the description of clinical Aeromonas phenospecies, pathogenic Vibrio spp., or P. shigelloides. The effectiveness of commercial depuration in reducing bacterial indicators was also examined. E. coli was reduced to < or = 230/100 g of flesh and liquor in 90.9% of mussel lots but in only 70.9% of infaunal bivalve lots. For total coliform elimination, mussels were also more effective. Total counts significantly (P < 0.005) correlated with numbers of Pseudomonas, Aeromonas, and Vibrio. Our data indicate that Salmonella and pathogenic bacteria indigenous to estuarine environments do not appear to be significant hazards in Galician molluscan shellfish. A reason for concern, however, is that clearance of E. coli to acceptable levels was not always achieved especially in infaunal bivalves.

Abstract
In order to discover the main microbial populations present throughout the process of beet sugar extraction and to identify the steps where possible control measures could be implemented, four Spanish beet sugar extraction factories were investigated. Eighteen stages were sampled at each factory and analyzed for several microbial groups and physicochemical parameters. Beets, cossettes, and diffusion juices were the most contaminated samples during beet sugar extraction, and mesophiles, thermophiles, and yeasts were the most numerous microbiota. Differences in contamination among factories and among stages of the sugar extraction process were statistically significant (P < 0.01). Beets and cossettes showed high numbers of mesophiles and lactic acid bacteria, with gum-forming bacteria and yeasts being at levels of >6 log CFU/g. Diffusion juices were highly contaminated with aerobic mesophiles, lactic acid bacteria, and thermophiles. Beet-washing water, equipment, and air were also important sources of contamination; in contrast, diffusion water showed moderate levels of microorganisms due to the acid treatment performed. Gum-forming bacteria, which are present at high levels from the first step of the extraction, survive the diffusion process and remain in the diffusion juice, where they may produce "gums" responsible for obstruction of filters. Thermophiles were present, although at levels lower than expected in most samples. Other microbial groups, particularly yeasts, may also contribute to the destruction of sugar. No biocides were used during the beet sugar extraction in the factories investigated.

Abstract
INTRODUCTION Liver transplant recipients frequently suffer gastrointestinal (GI) complications but their prevalence and their influence on quality of life remain unknown. OBJECTIVE The objective of this study was to asses the prevalence, impact on quality of life, and management of GI complications in liver transplant recipients. PATIENTS AND METHODS This was an epidemiologic, cross-sectional, multicenter study. Four hundred seventeen liver recipients were recruited in 14 centers. A questionnaire was filled for every patient. RESULTS The median age of the patients was 55 years. The median time since transplantation was 4.1 +/- 4 years. Whereas 19.2% presented some GI disease before transplantation, 49.4% showed this type of complication after transplantation. Diarrhea was the most prevalent GI complication, and anorexia was the GI disorder that affected patients daily activities the most frequently. GI complications were more frequent among female patients, subjects with pretransplantation hiatal hernia, and those readmitted after transplantation. Of the patients with GI complications, 70.9% received pharmacological treatment (89.7% with gastric protectors). Immunosuppressive therapy was also modified because of GI complications. Immunosuppressive drug dose was reduced in 18.1%, transiently stopped in 3.4%, and definitively stopped in 3.4% of cases. The drug most frequently changed was mycophenolate mofetil: dose reduction, 23.6%; transient withdrawal, 5.7%; and definitive withdrawal, 6.6%. CONCLUSIONS The prevalence of GI complications in the liver transplant population was approximately 50%. GI complications showed a significant impact on the quality of life of the patients. They were related to female gender, to pretransplantation GI pathology, and posttransplantation hospital admission. These complications were frequently managed with pharmacological therapy or with changes in immunosuppressive therapy.

Abstract
INTRODUCTION The aim of this study was to re-analyze door-to-door studies on neurological diseases among the elderly, in which vascular risk factors (VRF) were studied, describing methodological characteristics and prevalence of VRF. METHODS The surveys were identified in two phases. They were aimed at ascertaining prevalence of stroke, dementias or Parkinsonisms and, at the time of individual screening, had collected data on at least three of the following VRF: arterial hypertension (AHT), smoking habit, diabetes mellitus and hypercholesterolemia. A questionnaire was drawn up to collect the data reported in each study, and a database was constructed. VRF prevalences were quantified and analyzed using logistic regression. RESULTS The total of the re-analyzed population was 12,510 persons aged 70 years and over, residents in seven geographic areas during the period 1994-2002. Information available on VRF was essentially self-reported. The prevalence of self-reported AHT was 25.7 % in men and 44.2 % in women, and that of measured AHT was 61 % and 71.9 %, respectively. Populations with arterial pressure obtained by direct measurement registered 138 higher risks (OR: 1.74; 95 % CI: 1.51-2.01, and OR: 1.48; 95% CI: 1.33-1.64). Reported prevalence of diabetes, hypercholesterolemia and smoking habit were 14.3 %, 23.3% and 8.5 %, respectively. CONCLUSIONS There was a high prevalence of VRF among the Spanish elderly population. However, its relationship with dementia, Parkinsonisms and cerebrovascular disease could not be studied due to the poor quality of the VRF data. The differences between measured and self-reported arterial pressure suggest the existence of undetected AHT and wide scope for prevention.
