Abstract
6-Nitrodopamine is a novel catecholamine released by vascular tissues, heart, and vas deferens. The aim of this study was to investigate whether 6-nitrodopamine is released from the thoracic aorta and pulmonary artery rings of marmosets (Callithrix spp.) and to evaluate the relaxing and anti-contractile actions of this catecholamine. Release of 6-nitrodopamine, dopamine, noradrenaline, and adrenaline was assessed by liquid chromatography with tandem mass spectrometry (LC-MS/MS). The relaxations induced by 6-nitrodopamine and by the selective dopamine D2 receptor antagonist L-741,626 were evaluated on U-46619 (3 nM)-pre-contracted vessels. The effects of 6-nitrodopamine and L-741,626 on the contractions induced by electric-field stimulation (EFS), dopamine, noradrenaline, and adrenaline were also investigated. Both aorta and pulmonary artery rings exhibited endothelium-dependent release of 6-nitrodopamine, which was significantly reduced by the NO synthesis inhibitor L-NAME. Addition of 6-nitrodopamine or L-741,626 caused concentration-dependent relaxations of both vascular tissues, which were almost abolished by endothelium removal, whereas L-NAME and the soluble guanylate cyclase inhibitor ODQ had no effect on 6-nitrodopamine-induced relaxations. Additionally, pre-incubation with 6-nitrodopamine antagonized the dopamine-induced contractions, without affecting the noradrenaline- and adrenaline-induced contractions. Pre-incubation with L-741,626 antagonized the contractions induced by all catecholamines. The EFS-induced contractions were significantly increased by L-NAME, but unaffected by ODQ. Immunohistochemical assays showed no immunostaining of the neural tissue markers S-100 and calretinin in either vascular tissue. The results indicated that 6-nitrodopamine is the major catecholamine released by marmoset vascular tissues, and it acts as a potent and selective antagonist of dopamine D2-like receptors. 6-nitrodopamine release may be the major mechanism by which NO causes vasodilatation.

Abstract
AIMS In recent years, major improvements in breast cancer treatments have led to a significant increase in survival. Despite that, this population's quality of life (QoL) information is lacking, especially real-world data. MATERIALS AND METHODS This was a prospective, multicentre, observational study of female breast cancer patients, without prior systemic treatment, treated between 2012 and 2019 in private health care in Brazil. QoL was assessed by two questionnaires, the EQ-5D-5L and the EORTC-QLQ-BR23. Additional data were retrospectively collected. RESULTS The study comprised 1372 patients, most with early-stage disease (80.2% stages 0-II). At a median follow-up of 25.6 months, the estimated 3-year overall survival was 93.6%. Patients with locally advanced and metastatic breast cancer had the lowest visual analogue scale scores and the highest symptom burden in all dimensions of EQ-5D-5L, but with the most significant improvement after treatment. With the EORTC-QLQ-BR23 questionnaire, patients undergoing lumpectomy had a better perception of body image. Axillary dissection led to greater arm symptoms after 12 months, radiotherapy enhanced breast symptoms and patients treated with chemotherapy had significant worsening in the effects of systemic therapy compared with endocrine or HER2 therapy. Staging and immunohistochemical subtype correlated with survival and with several QoL parameters, but overall survival was not independently affected by patient-reported outcomes in this cohort. CONCLUSION Our results show that early diagnosis and access to treatments with fewer side-effects, such as endocrine or targeted therapy, and less aggressive surgeries are the best strategies to achieve a better QoL for breast cancer patients.

Abstract
Abstract
Background
The European Society of Cardiology (ESC) recommends the use of a 0/1h-algorithm for rapid triage of patients with suspected non-ST-elevation myocardial infarction (NSTEMI). To date, its impact on patient management and ultimately also safety when routinely applied in emergency departments (ED) is unknown. We therefore aimed to determine these important real-world outcome data.
Methods
In a prospective international multicenter study enrolling unselected patients presenting with suspected NSTEMI to the ED, we assessed the real-world feasibility, adherence, efficacy, effectiveness, and safety of the ESC 0/1h-algorithm using high-sensitivity cardiac troponin T embedded in routine clinical care. Patients with ST-segment elevation myocardial infarctions were excluded. Safety was quantified by the 30-day incidence of major adverse cardiac events (MACE, defined as the composite of cardiovascular death and myocardial infarction including the index event) in the rule-out group and in outpatients.
Results
Among 2296 patients, NSTEMI prevalence was 9.8% (224/2296). Feasibility was very high with a median time to the “1h-draw” of 65 minutes [q1 61, q3 72]. Adherence was very high with 94% (95% confidence interval [CI], 93–95) of patients managed without protocol violations. Effectiveness was very high: 98% (95% CI, 97–98) of patients triaged towards rule-out by the ESC 0/1h-algorithm did not require additional cardiac investigations including hs-cTnT measurements at later time points (e.g. 3–12h) or coronary CT-angiography in the ED. Median time to discharge from the ED was 150 [q1134, q3235] minutes in the overall population. The ESC 0/1h-algorithm triaged 62% (95% CI, 60–64) of patients towards rule-out and 13% (95% CI, 12–14) towards rule-in of NSTEMI. Overall, 71% (95% CI, 69–72) of patients underwent outpatient management (Figure 1). Safety of rule-out and outpatient management were very high with a 30-day MACE incidence of 0.2% (95% CI, 0–0.5) and 0.1% (95% CI, 0–0.2), respectively. These findings were consistent in several predefined subgroups.

Conclusions
These real-world data document the excellent feasibility, adherence, effectiveness, efficacy and safety of the ESC 0/1h-algorithm for the rapid management of patients presenting with suspected NSTEMI to the ED when applied in routine clinical practice.

Abstract
Abstract
Background
The ESC recommends the use of a 0/1h-algorithm for rapid triage of patients with suspected non-ST-elevation myocardial infarction (NSTEMI) using high-sensitivity cardiac troponin (hs-cTn) concentrations irrespective of renal function. Patients with renal dysfunction (RD, defined as a GFR <60ml/min) are at higher risk of NSTEMI and are presenting more often with elevated levels of hs-cTn even in absence of NSTEMI, which may contribute to an impaired efficacy and safety of the ESC 0/1h-algorithm.
Purpose
We aimed to assess and directly compare the real-world adherence, effectiveness, efficacy, and ultimately safety of the ESC 0/1h-algorithm when applied in patients with RD and normal renal function.
Methods
In a prospective international multicenter study enrolling unselected patients presenting with suspected NSTEMI to the ED, patients were assessed according to the ESC 0/1h-algorithm embedded in routine clinical care. Safety was quantified by the 30-day incidence of major adverse cardiac events (MACE, defined as the composite of cardiovascular death and myocardial infarction including the index event) in the rule-out group and in outpatients.
Results
Among 2296 enrolled patients, RD was present in 129 (6%) patients. NSTEMI prevalence was substantially higher in RD as compared with normal renal function (19% versus 9%, p<0.001). Adherence to the ESC 0/1h-algorithm protocol was excellent with no violations observed in patients with RD as compared with 132 (6%) violations in patients with normal renal function (p=0.004). Effectiveness was very high in RD and comparable to normal renal function: 94% of patients triaged towards rule-out by the ESC 0/1h-algorithm did not require additional cardiac investigations including hs-cTnT measurements at later time points (e.g. 3–12h) or coronary CT-angiography in the ED as compared with 98% in normal renal function. Median time to discharge or transfer from the ED was significantly longer in RD (285 minutes [q1174, q3392]) as compared with normal renal function (150 minutes [q1132, q3222]). Efficacy of the ESC 0/1h-algorithm was lower in RD as it triaged 13% of patients towards rule-out and 34% towards rule-in of NSTEMI as compared with 65% and 12% in normal renal function, respectively (p<0.001). Overall, 30% of patients with RD underwent outpatient management as compared with 73% in normal renal function (p<0.001). Safety of rule-out and outpatient management were excellent in RD with a 30-day MACE incidence of both 0% and comparable with 0.2% and 0.1% in normal renal function, respectively (p=0.010).
Conclusions
These real-world data document for the first time the excellent adherence, effectiveness, and safety of the ESC 0/1h-algorithm when routinely applied in patients with RD. Compared with patients with normal renal function, fewer patients with RD could be triaged towards rule-out or were treated as outpatients, most likely due to the higher prevalence of NSTEMI and comorbidities in RD.

Abstract
Abstract
Background
Atrial Fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice and confers a significant burden to morbidity and mortality. High-sensitivity cardiac troponin T (hs-cTnT) levels have provided a significant contribution in the early diagnosis of cardiovascular events; however, the significance of hs-cTnT elevation in the setting of acute AF is not clearly understood.
Purpose
The aim of this study was to evaluate the factors associated with hs-cTnT elevation and its prognostic implication in patients with acute AF.
Methods
This single-center prospective study included 406 consecutive patients who presented to the emergency department (ED) with acute AF. Acute AF was defined as a rapid, irregular, and chaotic atrial activity of <48 hours' duration including both the first symptomatic onset of chronic or persistent AF, and episodes of paroxysmal AF. The association between hs-cTnT and outcomes were evaluated using multivariate analyses.
Results
The mean age of the population was 67.3±12.2 and 74% were male. The median time from the onset of symptoms to ED consultation was 230 minutes (interquartile range: 123–450 minutes). The median hs-cTnT value was 12 ng/L, with 39% of patients with values above the 99 thpercentile. AF was reverted to sinus rhythm in 76% of the patients (83% attempted cardioversion). At one-year, AF recurrence was observed in 38% of the patients and major adverse cardiovascular events (MACE) (death, myocardial infarction, acute coronary syndrome or stroke) were observed in 6% of the patients. After adjusting for demographic and clinical characteristics in multivariate analysis, hs-cTnT elevation was associated with increasing age and left atrial area (p=0.001). Hs-cTnT levels were not associated with 1-year AF recurrence (p=0.132) or with AF reversion (p=0.869). Hs-cTnT levels were significantly higher in patients who experienced MACE at 1-year (12 ng/L vs 24 ng/L, p=0.001) and hs-cTnT was a predictor of MACE on multivariate analysis (OR 3.486, 95% CI 1.256–5.379, p=0.009).
Variable Result AF rate 110 (90–118) Atrial area, cm2 22 (19–27) Cardioversion attemped 82.5%
Conclusions
Hs-cTnT elevation accounted for a large proportion of patients with acute AF. Elevated levels of hs-cTnT were not associated with AF reversion or with 1-year AF recurrence, however hs-cTnT was highly predictive of MACE at 1-year.

Abstract
Abstract
Background
The European Society of Cardiology (ESC) recommends the use of a 0/1h-algorithm for rapid triage of patients with suspected non-ST-elevation myocardial infarction (NSTEMI) using high-sensitivity cardiac troponin (hs-cTn). Concerns were articulated about its efficacy and particularly safety when applied in patients presenting early (≤3 hours) after chest pain onset, as hs-cTn concentrations might still be very low or even undetectable in these high-risk patients.
Purpose
We aimed to assess the real-world effectiveness, efficacy, and ultimately safety of the ESC 0/1h-algorithm when routinely applied in early presenters.
Methods
In a prospective international multicenter study enrolling unselected patients presenting with suspected NSTEMI to the ED, patients were assessed according to the ESC 0/1h-algorithm using high-sensitivity cardiac troponin T embedded in routine clinical care. Patients with ST-segment elevation myocardial infarctions were excluded. Safety was quantified by the 30-day incidence of major adverse cardiac events (MACE, defined as the composite of cardiovascular death and myocardial infarction including the index event) in the rule-out group and in outpatients.
Results
Among 2296 patients, 819 (36%) were early presenters. NSTEMI prevalence in early presenters was 11%. Effectiveness was very high as 97% of patients triaged towards rule-out by the ESC 0/1h-algorithm did not require additional cardiac investigations including hs-cTnT measurements at later time points (e.g. 3–12h) or coronary CT-angiography in the ED. Median time to discharge or transfer from the ED was 150 minutes [q1130, q3215]. Efficacy of the ESC 0/1h-algorithm was very high: 67% of patients were triaged towards rule-out and 14% towards rule-in of NSTEMI. Overall, 75% of early presenters underwent outpatient management. Safety of rule-out and outpatient management were excellent in early presenters with a 30-day MACE incidence of both 0% and comparable with 0.3% and 0.1% in late presenters, respectively (p=ns).
Conclusions
These real-world data document for the first time the excellent effectiveness, efficacy and particularly safety of the ESC 0/1h-algorithm when routinely applied in early presenters. No differences in safety could be observed when compared with late presenters.

Abstract
Background In a significant percentage of advanced non-small-cell lung cancer (NSCLC) patients, tumor tissue is unavailable or insufficient for genetic analyses. We prospectively analyzed if circulating-free DNA (cfDNA) purified from blood can be used as a surrogate in this setting to select patients for treatment with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Patients and methods Blood samples were collected in 119 hospitals from 1138 advanced NSCLC patients at presentation (n = 1033) or at progression to EGFR-TKIs (n = 105) with no biopsy or insufficient tumor tissue. Serum and plasma were sent to a central laboratory, cfDNA purified and EGFR mutations analyzed and quantified using a real-time PCR assay. Response data from a subset of patients (n = 18) were retrospectively collected. Results Of 1033 NSCLC patients at presentation, 1026 were assessable; with a prevalence of males and former or current smokers. Sensitizing mutations were found in the cfDNA of 113 patients (11%); with a majority of females, never smokers and exon 19 deletions. Thirty-one patients were positive only in plasma and 11 in serum alone and mutation load was higher in plasma and in cases with exon 19 deletions. More than 50% of samples had <10 pg mutated genomes/µl with allelic fractions below 0.25%. Patients treated first line with TKIs based exclusively on EGFR positivity in blood had an ORR of 72% and a median PFS of 11 months. Of 105 patients screened after progression to EGFR-TKIs, sensitizing mutations were found in 56.2% and the p.T790M resistance mutation in 35.2%. Conclusions Large-scale EGFR testing in the blood of unselected advanced NSCLC patients is feasible and can be used to select patients for targeted therapy when testing cannot be done in tissue. The characteristics and clinical outcomes to TKI treatment of the EGFR-mutated patients identified are undistinguishable from those positive in tumor.

Abstract
BACKGROUND Individuals with Williams syndrome (WS) show difficulties in attributing false beliefs, whereas they are better at attributing emotions. This study examines whether being asked about the emotion linked to a false belief, instead of explicitly about the belief, facilitates performance on theory of mind (ToM) tasks. METHOD Thirty children with WS and 90 typically developing children, who were individually matched on mental age (50-112 months), were administered six explicit (i.e. questions on belief) and six implicit (i.e. questions on emotion) trials of false belief tasks. RESULTS Theory of mind competences were related to cognitive development. Children with WS performed comparably to typically developing children on the emotion questions. CONCLUSION Correct answers to questions on emotion reveal an implicit understanding of false belief. The Representational redescription process could be impaired in the domain of ToM in this population. This finding has relevant implications for the design of supports aiming to optimise the development of ToM competences in individuals with WS.

Abstract
Se evaluó el efecto sobre la producción de metano de la inclusión creciente (25, 50 y 75 %) de cinco plantas nativas de sabanas inundables (Senna occidentalis, Enterolobium schomburgkii, Galactia jussiaeana, Belencita nemorosa y Ambrosia peruviana), sobre una dieta base de Brachiaria humidicola. Los tratamientos fueron incubados anaeróbicamente con fluido ruminal a 39°C por 24 h y después del proceso de fermentación, se determinó la producción de gas, metano, ácidos grasos volátiles (AGV), amonio y degradación de la materia seca (MSD). La inclusión en la dieta de 50 y 75% de todas las plantas, incrementaron el contenido de amonio ruminal, con valores entre 189 - 282 mg/L. Ninguna de las plantas modificó la concentración de AGVT (44-62 mmol/L). La producción de metano no se redujo significativamente con ningún tratamiento (p>0,05), aunque con S. occidentalis (75%) este parámetro fue inferior en un 18%, además, se incrementó la MSD y los niveles de butirato, isobutirato y valerato. Con E. schomburgkii (75%), la metanogénesis también se redujo en un 15%, sin embargo, este efecto estuvo acompañado de una disminución en la MSD y producción de gas. En conclusión, ninguna de las plantas mostró potencial para reducir la producción de metano, no obstante, las especies se convierten en alternativas nutricionales útiles para complementar el aporte proteico de la dieta en los sistemas ganaderos ubicados en condiciones de sabanas inundables.

Abstract
Primordial germ cells (PGCs) have long been considered the link between one generation and the next. PGC specification begins in the early embryo as a result of a highly orchestrated combination of transcriptional and epigenetic mechanisms. Understanding the molecular events that lead to proper PGC development will facilitate the development of new treatments for human infertility as well as species conservation. This article describes the latest, most relevant findings about the mechanisms of PGC formation, emphasizing human PGC. It also discusses our own laboratory's progress in using transdifferentiation protocols to derive human PGCs (hPGCs). Our preliminary results arose from our pursuit of a sequential hPGC induction strategy that starts with the repression of lineage-specific factors in the somatic cell, followed by the reactivation of germ cell-related genes using specific master regulators, which can indeed reactivate germ cell-specific genes in somatic cells. While it is still premature to assume that fully functional human gametes can be obtained in a dish, our results, together with those recently published by others, provide strong evidence that generating their precursors, PGCs, is within reach.

Abstract
Peripheral blood mononuclear cells (PBMC) from chronic hepatitis C virus-infected persons can harbour viral variants that are not detected in plasma samples. We explored the presence and persistence of HCV genotypes in plasma and PBMC cultures from 25 HCV-monoinfected and 25 HIV/HCV-coinfected patients with haemophilia. Cell cultures were performed at different time points between 1993 and 2010-2011, and the HCV genome was examined in culture supernatants. Sequential plasma samples were studied during the same time period. Analysing sequential plasma samples, 21% of patients had mixed-genotype infections, while 50% had mixed infections determined from PBMC culture supernatants. HIV coinfection was significantly associated with the presence of mixed infections (OR = 4.57, P = 0.02; 95% CI = 1.38-15.1). In our previous study, genotype 1 was found in 72% of 288 patients of this cohort. Similar results were obtained with the sequential plasma samples included in this study, 69% had genotype 1. However, when taking into account plasma samples and the results from PBMC supernatants, genotype 1 was identified in 94% of the population. The PBMC-associated variants persisted for 10 years in some subjects, emphasizing their role as long-term reservoirs. The presence of genotype 1 in PBMC may be associated with therapeutic failure and should not be disregarded when treating haemophilic patients who have been infected by contaminated factor concentrates. The clinical implications of persistent lymphotropic HCV variants deserve further examination among multiple exposed groups of HCV-infected patients.

Abstract
Hepatitis B virus (HBV) infection is a serious global health problem. Approximately 2 billion people worldwide have been infected, and approximately 350 million individuals currently suffer from HBV-induced chronic liver infection, which causes 600,000 deaths annually from chronic hepatitis, cirrhosis and hepatocellular carcinoma. HBV is classified in eight genotypes (A-H), and two more have been proposed (I-J). In this paper, complete genome sequences of nine Uruguayan HBV are reported. Five samples belong to genotype F1b and one to genotype A2. Three HBV recombinants were detected: A1/F1b, A2/F1b and D3/F1b. The following mutations were detected: a G1896A substitution, a 33-nucleotide deletion from position 2896 to 2928 in the Pre-S1 region involving Pre-S1 residues 3-13, a 33-nt deletion in the Pre-S1 region involving nt 2913-2945 and Pre-S1 residues 9-19. More F genotypes strains than expected were detected in this study, supporting the hypothesis that there are more people of indigenous origin than declared in our population. Also, one third of the samples analyzed were recombinants. This cannot be explained by the low HBV prevalence in Uruguay, but a high HBV infection rate in drug addicts and dialysis patients could act in favor of multiple-genotype HBV infections that could lead to recombination.

Abstract
This study investigated the co-treatment of landfill leachate/domestic wastewater in bench-scale activated sludge (AS) reactors to determine whether the slowly biodegradable organic matter (SBOM) was removed rather than diluted. The AS reactors were loaded with mixtures of raw leachate and leachate that was pretreated by air stripping. The tested volumetric ratios were 0%, 0.2%, 2% and 5%. For all of the tested conditions, the reactors performed better when pretreated leachate was used rather than raw leachate, and the best volumetric ratio was 2%. The following removals were obtained: 97% for the biochemical oxygen demand (BOD5,20), 79% for total suspended solids, 77% for dissolved organic carbon and 84% for soluble chemical oxygen demand. Most of the pretreated leachate SBOM (65%) was removed rather than diluted or adsorbed into the sludge, as confirmed by Fourier transform infrared (FTIR) spectroscopy analyses.

Abstract
BACKGROUND AND PURPOSE B(1) and B(2) kinin receptors are involved in pain transmission but they may have different roles in the muscle pain induced by intense exercise or inflammation. We investigated the contribution of each of these receptors, and the intracellular pathways involved, in the initial development and maintenance of the muscle pain associated with inflammation-induced tissue damage. EXPERIMENTAL APPROACH Mechanical hyperalgesia was measured using the Randall-Selitto apparatus after injecting 5% formalin solution into the gastrocnemius muscle in mice treated with selective antagonists for B(1) or B(2) receptors. The expression of kinin receptors and cytokines and the activation of intracellular kinases were monitored by real-time PCR and immunohistochemistry. KEY RESULTS The i.m. injection of formalin induced an overexpression of B(1) and B(2) receptors. This overexpression was associated with the mechanical hyperalgesia induced by formalin because treatment with B(1) receptor antagonists (des-Arg(9) [Leu(8)]-BK, DALBK, and SSR240612) or B(2) receptor antagonists (HOE 140 and FR173657) prevented the hyperalgesia. Formalin increased myeloperoxidase activity, and up-regulated TNF-α, IL-1β and IL-6 in gastrocnemius. Myeloperoxidase activity and TNF-α mRNA expression were inhibited by either DALBK or HOE 140, whereas IL-6 was inhibited only by HOE 140. The hyperalgesia induced by i.m. formalin was dependent on the activation of intracellular MAPKs p38, JNK and PKC. CONCLUSIONS AND IMPLICATIONS Inflammatory muscle pain involves a cascade of events that is dependent on the activation of PKC, p38 and JNK, and the synthesis of IL-1β, TNF-α and IL-6 associated with the up-regulation of both B(1) and B(2) kinin receptors.

Abstract
BACKGROUND WHO International Standards (IS) are provided for the calibration and validation of diagnostic and screening assays, e.g. for hepatitis B virus (HBV). HBV forms numerous subgenotypes and the current IS for HBV DNA reflects subgenotype A2. OBJECTIVE A reference panel with the most prevalent subgenotypes should facilitate evaluation of genotype-specific detection efficiencies. STUDY DESIGN 215 HBV positive plasma samples collected worldwide were characterized for HBV markers and sequenced. Fifteen subgenotype A1, A2, B2, B4, C2, D1, D3, E, F2 and G samples were selected for the panel. The lyophilized samples were tested in parallel with the IS in an international collaborative study with 16 laboratories using 13 different nucleic acid amplification techniques (NATs). RESULTS Eight of 13 NAT had a HBV DNA detection efficiency which was independent of the genotype and consistent with the IS, while with five assays, certain deviations were noted, particularly with genotype F which was under quantitated or even missed by three assays. The panel was accepted by the WHO as the "1st WHO International Reference Panel for HBV Genotypes for HBV NAT-Based Assays". CONCLUSIONS The evaluation of HBV DNA assays should include many different genotypes. The WHO Reference Panel is universally available for manufacturers of HBV DNA assays, diagnostic laboratories and control authorities to facilitate standardized validation of HBV genotype specific detection efficiency of both diagnostic (quantitative and qualitative) and screening NAT assays.

Abstract
Laser Doppler flowmetry (LDF) is now commonly used in clinical research to monitor microvascular blood flow. However, the dependence of the LDF signal on the microvascular architecture is still unknown. That is why we propose a new laser Doppler flowmeter for depth dependent monitoring of skin microvascular perfusion. This new laser Doppler flowmeter combines for the first time, in a device, several wavelengths and different spaced detection optical fibres. The calibration of the new apparatus is herein presented together with in vivo validation. Two in vivo validation tests are performed. In the first test, signals collected in the ventral side of the forearm are analyzed; in the second test, signals collected in the ventral side of the forearm are compared with signals collected in the hand palm. There are good indicators that show that different wavelengths and fibre distances probe different skin perfusion layers. However, multiple scattering may affect the results, namely the ones obtained with the larger fibre distance. To clearly understand the wavelength effect in LDF measurements, other tests have to be performed.

Abstract
OBJECTIVE Laparoscopic adenomectomy 150 is a minimally invasive alternative to open surgery in large prostates. Our aim is to discuss our series of 59 patients treated by means of laparoscopic adenomectomy with precise vascular control. MATERIALS AND METHODS Between June 2003 and June 2006, a total of 59 patients with a mean age of 65.5 years (51 to 82), underwent laparoscopic extraperitoneal adenomectomy. All the patients had a history of lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH). The mean International Prostate Symptom Score (IPSS) was 20 points (16-22). The information was collected prospectively in a database. The analysis was performed subsequently. RESULTS All 59 adenomas were completely removed laparoscopically without conversion to open surgery. The mean preoperative prostate volume by ultrasound was 108.5 cc (75-150). The average operating time was 123 minutes (90-180). The mean loss of blood was 415 ml (50-1500) and 4 patients (14.8%) required a blood transfusion. Two (7.4%) of the patients presented perioperative complications. The mean hospital stay and the bladder catheterization time were 3.5 (2-7) and 4.2 (3-7) days respectively. CONCLUSIONS Laparoscopic extraperitoneal simple prostatectomy is an effective procedure for the treatment of large prostatic adenomas. There seems to be less perioperative morbidity and, in our experience, this technique seems to be feasible and reproducible; however, its learning curve is a complicated matter to deal with.

Abstract
INTRODUCTION We describe the technique and present the preliminary results of the laparoscopic radical cystectomy technique with the extracorporeal creation of a "y" shaped ileal orthotopic neobladder using non-absorbable mechanical suture (Fontana). MATERIALS AND METHOD We describe the technique step by step and we present a series of 15 patients that underwent this surgery between November 2005 and August 2009, with special emphasis on the duration of the surgery, urinary diversion time, intraoperative and postoperative complications, daytime and night time continence and the frequency of postoperative micturition. RESULTS The mean follow-up of the series was 24 months (6-32). The mean duration of surgery was 280 (range 210-345) minutes and the mean urinary diversion time was 54.5 (range 40-75) minutes. There were no intraoperative complications and the average hospitalization time was 7 (range 5-15) days. During the follow-up, there were 5 late postoperative complications, 2 cases of urinary infection with good response to antibiotic treatment and 3 uretero-neovesical anastomosis strictures, which were treated with percutaneous balloon dilation, with a good functional result. No lithiasis was found in the neobladder. Complete daytime continence was obtained in 13/14 patients (92.9%) and complete night time continence in 6/14 (42.9%). One patient (6.7%) required clean intermittent self-catheterization as the patient did not micturate spontaneously. CONCLUSIONS The creation of a "Y" shaped ileal orthotopic neobladder using non-absorbable mechanical suture is a feasible, fast and safe technique and it provides promising functional results. Further follow-up is required to determine its long-term results.

Abstract
OBJECTIVE A pilot study to assess the feasibility of implementing a hospital protocol for systematic nutritional screening of admitted patients. METHOD Descriptive cross-sectional study. Patients admitted to the Orthopedic Surgery Department of the Regional Hospital of Alcañiz were systematically included within the first 48 hours of hospitalization, from February to September of 2007. The screening methods used were the Nutritional Risk Index (NRI), the CONUT Nutritional Control system, and an indicator based on SENPE recommendations. The need for nutritional support was defined as the presence of any of the following instances: moderate to severe hyponutrition according to the NRI or CONUT methods, or hyponutrition according to the adapted SENPE recommendations. RESULTS 36.4% of the patients assessed need nutritional support. The rate of hyponutrition according to CONUT is 13.6%, by SENPE criteria is 27.3%, and by the NRI 29.5%. The inter-method agreement is statistically significant and clinically acceptable: Kappa between NRI and CONUT 0.547, between NRI and SENPE 0.609, and between CONUT and SENPE 0.593. CONCLUSIONS The implementation of a structured protocol for collecting the anthropometrical and biochemical parameters implicating a multidisciplinary hospital team enables identifying those patients in whom appropriate nutritional support may improve their prognosis during hospital stay.
