Abstract
Introduction The patient experience is defined as all the interactions that occur between patients and the healthcare system. The experience of patients with respiratory disease with home respiratory treatments (HRT) is not captured in currently available Patient-Reported Outcome Measures (PROM). We present the psychometric validation of the Patient-Reported Experience Measure (PREM) 'HowRwe' in Spanish and for respiratory patients with HRT. Methods After translation following ISPOR guidelines (International Society for Pharmacoeconomics and Outcomes Research), the questionnaire was administered to adult respiratory patients who were receiving treatment at Hospital Universitario de La Princesa. The administration was done in two stages with 6 months of difference between the pre- and post-test. Results We studied 228 respiratory patients, with a mean (SD) age of 64.1 (13.2) years, 52.2% were men, 68.0% were married or coupled, and 56.6% were retired. Reliability coefficients of the scale were adequate, with α = .921 and Ω = .929 for pre-test, and α = .940 and Ω = .958 for post. The confirmatory factor analysis tested for pre- and post-intervention, showed an excellent overall fit: χ2(2) = 49.380 (p < .001), CFI = .941 and SRMR = .072; and χ2(2) = 37.579 (p < .001), CFI = .982 and SRMR = .046, respectively. No statistically significant associations were observed for neither age, adherence nor quality of life, except between HowRwe post-test and quality of life pre-test (r = .14 [.01,.26]; p = .035). No significant differences were found in sociodemographic variables. No differences in pre-test or post-test were found in effect of HRT. 85.6% of patients found the content of HowRwe "Useful", and the preferred channel to respond it were paper, app and email. Conclusions The Spanish version of the 'HowRwe' questionnaire to measure the experience in respiratory patients with home respiratory treatments (HRT), has adequate psychometric properties and conceptual and semantic equivalence with the original English version.

Abstract
Introduction
Need of permanent pacemaker implantation (PPI) continues to be an undesirable side-effect after transcatheter aortic-valve replacement (TAVR), mostly in self-expandable (SE) valves. Recently, different techniques have arisen, as the cusp-overlap projection (COP) to better control TAVR implantation depth, and the sequential atrial pacing (AP) after deployment to test atrioventricular (AV) conduction. However, the combination of both techniques has not been tested yet. We sought to determine if the combination of COP and AP can decrease the need of PPI after SE aortic prothesis.
Methods
We retrospectively studied 253 patients in sinus rhythm who underwent TAVR procedure with SE valves between 2018 and 2021, and compared standard implantation (n=143) with the combined use of COP and AP (n=110). Patients with permanent atrial fibrillation or previous pacemaker were excluded. Assessment included EKG, imaging, immediate and 30-day follow-up. AP was performed after TAVR in the absence of complete AV block at rates of 70 to 120 beats/min (or until AV Block was observed).
Results
Median patient age was 80 [75–85] years old and 52.2% were female. No significant differences could be appreciated in baseline demographics or treatment. Both cohorts had similar EKG intervals and similar rates of conduction disturbances (Table 1). Patients with CO+AP displayed bigger outflow tract perimeters (p=0.003). Also, the CO+AP cohort underwent more frequent predilation prior to valve deployment (p<0.001).
During TAVR complete AV block occurred in 4.6% of the CO+AP cohort vs 14.8% in the standard group (p=0.002). Among patients with transient or no conduction disturbances immediately after deployment, AP showed Wenckebach phenomenon in 22 subjects at a median heart rate of 110 bpm. PPI was considered within 24 hours when Wenckebach phenomenon developed below 90 bpm. Testing atrio-his conduction led to a significant decrease in the next 24-hour surveillance with a temporary pacemaker in the COP+AP cohort (23.1% vs 90.2% in the standard cohort, p<0.0001). Time of hospitalization was significantly reduce in the COP + AP cohort (mean stay 2 [1; 3] days vs 5 [4; 8] days in the standard cohort, p<0.0001), and the total amount of total PPI at that time was still lower CO+AP group (12.7% in CO+AP group vs 21.0% in the standard, p=0.121) (Figure 1).
On a 30-day follow-up, the rate of PPI after TAVR remained significantly decreased in the COP+AP cohort (p=0.039, Figure 1).
Conclusion
Combining COP with AP reduces the need of immediate and short-term PPI and reducing on-admission conduction surveillance and hospitalization stay after self-expandable TAVR.

Abstract
Introduction
Transcatheter aortic-valve replacement (TAVR) procedure has been simplified, being now a less-invasive minimalist strategy the standard of treatment. Therefore, length of hospitalization has decreased, and early-discharge (ED) (<72 hour) protocols are in development.
Lately, additional techniques to optimize TAVR procedure have arisen, such as the use of radial approach as the secondary access, conscious sedation, cusp overlap projection (COP) to better control the implantation depth in self-expanding (SE) valves, or atrial pacing (AP) after deployment to test atrioventricular (AV) conduction. With the combination of these 4 maneuvers, we have developed an ED protocol, and hereby present the immediate results.
Methods
We prospectively studied 176 patients who underwent staged and transfemoral TAVR procedure with our novel protocol between May 2020 and December 2021 (Protocol) and compared them with a retrospective cohort of 175 patients who underwent standard TAVR between January 2018 and April 2020 (Standard). The protocol cohort included the use of conscious sedation with midazolam and fentanyl, routine radial approach as the secondary access, use of the CO projection, and AP after deployment in the absence of complete AV block, at rates of 70 to 120 beats/min (or until AV Block was observed) in 10 beats/min increments for a total of 20 beats at each increment. As part of this protocol, patients remained in general cardiology ward, avoiding ICU stay, with rapid recovery and early mobilization (After 6 hours in the absence of bleeding). In the absence of complications patients were discharged within 24–48 hours and reviewed a week and a month later in clinic. Initial assessment included EKG, echocardiogram, in hospital and 30-day follow-up.
Results
Median patient age was 80 years old and 49.9% were female. Despite higher rates of hypertension in the standard cohort (p=0.038), no significant differences could be appreciated in baseline demographics, EKG or imaging findings (Table).
Even with higher rates of predilation, CO and AP, the length of procedure and the use of contrast was lower in the protocol cohort. Rates of intraprocedural AV block were similar among groups (p=p.21), but AP led to a significant lower need of temporary pacemaker surveillance (p<0.0001). The use of radial access also tend to diminish immediate bleeding and vascular complications.
According to protocol, the median length of stay was reduced to 2 [1; 4] days (p<0.0001).
At a 30-day follow up, the incidence of major adverse cardiac events was low and similar among groups (p=0.67) (Figure), with no significant differences in the incidence of permanent pacemaker implantation, heart failure admission, bleeding o vascular complication (Figure)
Conclusion
A simplified TAVR protocol combining radial access, CO, AP can be adopted safely, leading to TAVR patients early discharge, with no major events on an immediate 30-day follow-up.

Abstract
Abstract
Background
In the past years, transcatheter aortic-valve replacement (TAVR) has risen as a feasible and safe option for patients with aortic stenosis, been now an option of treatment in low-risk (Euroscore II <4%) patients over 75 years.1
Evidence of this treatment with self-expandable supraanular bioprothesis Evolut have widely proven to be no inferior to surgical valve replacement.2 Nevertheless, experience of the annular self-expandable prothesis Portico available in this population is scarce.
Purpose
We present our early experience with the annular self-expandable prothesis Portico in our low-risk population.
Methods
We retrospectively studied 219 symptomatic low-risk patients with who underwent TAVR procedure with self-expandable valves between 2018 and 2021. Assessment included echocardiogram, immediate and 30-day follow-up, as well as last clinical visit follow-up. 92 subjects received an annular Portico prothesis. Our reference group was the suprannular prothesis Evolut (n=127), already validated for low-risk patients in clinical trials.2
Results
The mean age of the patients was 79 years, 43.4% were women, and all the patients were at low surgical risk (2.2 [1.6; 3.0]). No significant differences could be appreciated in baseline demographics and echocardiographic characteristics except for body mass index (BMI), which was higher in the Portico group (p<0.001) (Table).
Procedure length was similar, with the particular need of higher predilation in the Portico group according to recommendations. Both self-expandable prothesis had similar rates of intraprocedural atrioventricular block, bleeding, vascular complications, stroke, and new onset atrial fibrillation.
Mean aortic-valve gradients before discharge were lower at the suprannular Evolut group than in the annular Portico group, and immediate residual aortic regurgitation was almost inexistent in both groups (Table 1).
At a 30-day follow up, the incidence of major adverse cardiac events was low and similar among groups (p=0.6) (Figure 1), with no significant differences in the incidence of permanent pacemaker implantation, heart failure admission, stroke, bleeding o vascular complication (Figure 1).
Conclusion
Annular aortic self-expandable prothesis Portico is a feasible alternative for patients with AS and low surgical risk who undergo TAVR procedure.

Abstract
Background Coronavirus-associated acute respiratory distress syndrome (CARDS) has limited effective therapy to date. NLRP3 inflammasome activation induced by SARS-CoV-2 in COVID-19 contributes to cytokine storm. Methods This randomised, multinational study enrolled hospitalised patients (18–80 years) with COVID-19-associated pneumonia and impaired respiratory function. Eligible patients were randomised (1:1) via Interactive Response Technology to DFV890 + standard-of-care (SoC) or SoC alone for 14 days. Primary endpoint was APACHE II score at Day 14 or on day-of-discharge (whichever-came-first) with worst-case imputation for death. Other key assessments included clinical status, CRP levels, SARS-CoV-2 detection, other inflammatory markers, in-hospital outcomes, and safety. Findings Between May 27, 2020 and December 24, 2020, 143 patients (31 clinical sites, 12 countries) were randomly assigned to DFV890 + SoC (n = 71) or SoC alone (n = 72). Primary endpoint to establish clinical efficacy of DFV890 vs. SoC, based on combined APACHE II score, was not met; LSM (SE), 8·7 (1.06) vs. 8·6 (1.05); p = 0.467. More patients treated with DFV890 vs. SoC showed ≥ 1-level improvement in clinical status (84.3% vs. 73.6% at Day 14), earlier clearance of SARS-CoV-2 (76.4% vs. 57.4% at Day 7), and mechanical ventilation-free survival (85.7% vs. 80.6% through Day 28), and there were fewer fatal events in DFV890 group (8.6% vs. 11.1% through Day 28). DFV890 was well tolerated with no unexpected safety signals. Interpretation DFV890 did not meet statistical significance for superiority vs. SoC in primary endpoint of combined APACHE II score at Day 14. However, early SARS-CoV-2 clearance, improved clinical status and in-hospital outcomes, and fewer fatal events occurred with DFV890 vs. SoC, and it may be considered as a protective therapy for CARDS.

Abstract
Background Cellular prion protein (PrPC) is a cell surface GPI-anchored protein, usually known for its role in the pathogenesis of human and animal prionopathies. However, increasing knowledge about the participation of PrPC in prion pathogenesis contrasts with puzzling data regarding its natural physiological role. PrPC is expressed in a number of tissues, including at high levels in the nervous system, especially in neurons and glial cells, and while previous studies have established a neuroprotective role, conflicting evidence for a synaptic function has revealed both reduced and enhanced long-term potentiation, and variable observations on memory, learning, and behavior. Such evidence has been confounded by the absence of an appropriate knock-out mouse model to dissect the biological relevance of PrPC, with some functions recently shown to be misattributed to PrPC due to the presence of genetic artifacts in mouse models. Here we elucidate the role of PrPC in the hippocampal circuitry and its related functions, such as learning and memory, using a recently available strictly co-isogenic Prnp0/0 mouse model (PrnpZH3/ZH3). Results We performed behavioral and operant conditioning tests to evaluate memory and learning capabilities, with results showing decreased motility, impaired operant conditioning learning, and anxiety-related behavior in PrnpZH3/ZH3 animals. We also carried in vivo electrophysiological recordings on CA3-CA1 synapses in living behaving mice and monitored spontaneous neuronal firing and network formation in primary neuronal cultures of PrnpZH3/ZH3 vs wildtype mice. PrPC absence enhanced susceptibility to high-intensity stimulations and kainate-induced seizures. However, long-term potentiation (LTP) was not enhanced in the PrnpZH3/ZH3 hippocampus. In addition, we observed a delay in neuronal maturation and network formation in PrnpZH3/ZH3 cultures. Conclusion Our results demonstrate that PrPC promotes neuronal network formation and connectivity. PrPC mediates synaptic function and protects the synapse from excitotoxic insults. Its deletion may underlie an epileptogenic-susceptible brain that fails to perform highly cognitive-demanding tasks such as associative learning and anxiety-like behaviors.

Abstract
COVID-19 has overloaded national health services worldwide. Thus, early identification of patients at risk of poor outcomes is critical. Our objective was to analyse SARS-CoV-2 RNA detection in serum as a severity biomarker in COVID-19. Retrospective observational study including 193 patients admitted for COVID-19. Detection of SARS-CoV-2 RNA in serum (viremia) was performed with samples collected at 48-72 h of admission by two techniques from Roche and Thermo Fischer Scientific (TFS). Main outcome variables were mortality and need for ICU admission during hospitalization for COVID-19. Viremia was detected in 50-60% of patients depending on technique. The correlation of Ct in serum between both techniques was good (intraclass correlation coefficient: 0.612; p < 0.001). Patients with viremia were older (p = 0.006), had poorer baseline oxygenation (PaO2/FiO2; p < 0.001), more severe lymphopenia (p < 0.001) and higher LDH (p < 0.001), IL-6 (p = 0.021), C-reactive protein (CRP; p = 0.022) and procalcitonin (p = 0.002) serum levels. We defined "relevant viremia" when detection Ct was < 34 with Roche and < 31 for TFS. These thresholds had 95% sensitivity and 35% specificity. Relevant viremia predicted death during hospitalization (OR 9.2 [3.8-22.6] for Roche, OR 10.3 [3.6-29.3] for TFS; p < 0.001). Cox regression models, adjusted by age, sex and Charlson index, identified increased LDH serum levels and relevant viremia (HR = 9.87 [4.13-23.57] for TFS viremia and HR = 7.09 [3.3-14.82] for Roche viremia) as the best markers to predict mortality. Viremia assessment at admission is the most useful biomarker for predicting mortality in COVID-19 patients. Viremia is highly reproducible with two different techniques (TFS and Roche), has a good consistency with other severity biomarkers for COVID-19 and better predictive accuracy.

Abstract
Background Network alterations underlying neurodegenerative diseases often precede symptoms and functional deficits. Thus, their early identification is central for improved prognosis. In Huntington’s disease (HD), the cortico-striatal networks, involved in motor function processing, are the most compromised neural substrate. However, whether the network alterations are intrinsic of the striatum or the cortex is not fully understood. Results In order to identify early HD neural deficits, we characterized neuronal ensemble calcium activity and network topology of HD striatal and cortical cultures. We used large-scale calcium imaging combined with activity-based network inference analysis. We extracted collective activity events and inferred the topology of the neuronal network in cortical and striatal primary cultures from wild-type and R6/1 mouse model of HD. Striatal, but not cortical, HD networks displayed lower activity and a lessened ability to integrate information. GABAA receptor blockade in healthy and HD striatal cultures generated similar coordinated ensemble activity and network topology, highlighting that the excitatory component of striatal system is spared in HD. Conversely, NMDA receptor activation increased individual neuronal activity while coordinated activity became highly variable and undefined. Interestingly, by boosting NMDA activity, we rectified striatal HD network alterations. Conclusions Overall, our integrative approach highlights striatal defective network integration capacity as a major contributor of basal ganglia dysfunction in HD and suggests that increased excitatory drive may serve as a potential intervention. In addition, our work provides a valuable tool to evaluate in vitro network recovery after treatment intervention in basal ganglia disorders.

Abstract
Recent progress in the field of human induced pluripotent stem cells (iPSCs) has led to the efficient production of human neuronal cell models for in vitro study. This has the potential to enable the understanding of live human cellular and network function which is otherwise not possible. However, a major challenge is the generation of reproducible neural networks together with the ability to interrogate and record at the single cell level. A promising aid is the use of biomaterial scaffolds that would enable the development and guidance of neuronal networks in physiologically relevant architectures and dimensionality. The optimal scaffold material would need to be precisely fabricated with submicron resolution, be optically transparent, and biocompatible. Two-photon polymerisation (2PP) enables precise microfabrication of three-dimensional structures. In this study, we report the identification of two biomaterials that support the growth and differentiation of human iPSC-derived neural progenitors into functional neuronal networks. Furthermore, these materials can be patterned to induce alignment of neuronal processes and enable the optical interrogation of individual cells. 2PP scaffolds with tailored topographies therefore provide an effective method of producing defined in vitro human neural networks for application in influencing neurite guidance and complex network activity.

Abstract
Abstract
Introduction
Resting full-cycle ratio (RFR) is a novel non-hyperemic index of coronary stenosis severity, independent of the timing within the cardiac cycle. Recent data has demonstrated good correlation between RFR and Fractional Flow Reserve (FFR) in stable coronary disease (SCD). However, there are no data regarding the reliability of RFR in non-culprit arteries of patients presenting with acute myocardial infarction (AMI).
Purpose
To study the diagnostic accuracy of RFR versus FFR in the non-culprit artery in AMI compared to stable lesions.
Methods
RFR, FFR, Coronary Flow Reserve (CFR), Index of Microcirculatory Resistance (IMR), and Resistance Reserve Ratio (RRR) were calculated in 67 patients with AMI and an intermediate lesion in a non-culprit artery (median time from primary PCI to study: 48 hours). Data were compared with those of a retrospective group of 66 patients with SCD.
Results
There was a higher proportion of males among patients of the AMI group (85% vs 62%, p=0.0026). Mean age was 64.5±11 years, being AMI cohort younger at presentation [62±11 vs 67±12 years in SCD cohort (p=0.04)]. Patients with AMI had a significantly lower prevalence of hypertension (52% vs 75%, p=0.006), diabetes (10% vs 32%), p=0.002) and hyperlipemia (37% vs 79%, p=0.002).
Coronary physiology parameters showed a non-normal distribution, and are expressed as median [IQR] (Table 1). In patients with AMI, FFR was lower than in patients with SCD. In contrast, RFR showed no significant difference. Both CFR and RRR were higher in the AMI group. No significant differences in IMR were found between cohorts.
Importantly, in the AMI group the correlation between RFR and FFR was 0.84 and the overall agreement 82%, with rates of false positive and negative of 15% and 3%, respectively. In SCD the correlation was 0.81 with a lower overall agreement of 69%, due mostly to a higher rate of false positive RFR (28%) (Figure 1).
Table 1. Microcirculatory parameters in non-culprit artery (AMI) and stable coronary disease (SCD) AMI (N=66) Stable (N=67) p value FFR 0.84 [0.76–0.9] 0.84 [0.76–0.9] 0.006 RFR 0.89 [0.82–0.94] 0,9 [0.84–0.94] 0.24 CFR 2.2 [1.7–3.1] 1.8 [1.1–2.6] 0.011 IMR 17 [14–27] 25 [14–38] 0.051 RRR 2.7 [2.17 - 3.9] 2.1 [1.4–3.1] 0.005 Median [IQR].
Figure 1. Correlation between RFR and FFR valueS
Conclusions
RFR shows a good correlation with FFR in AMI. Surprisingly, overall agreement is higher in the non-culprit artery in an acute setting, with a lower percentage of false positive results.

Abstract
Abstract
Introduction
Resting full-cycle ratio (RFR) has been recently described as a non-hyperemic index of coronary stenosis with good concordance with Fractional Flow Reserve (FFR). However, there is no information concerning the influence of microvascular function and coronary flow on RFR results.
Purpose
To determine if the accuracy of this novel parameter might be influenced by changes in microvascular function.
Methods
133 patients admitted in our center between July 2016 and December 2017 underwent coronary physiology study of an angiographically intermediate lesion. 67 subjects presented with AMI and an intermediate lesion in a non-culprit artery, and 66 subjects stable coronary disease. We performed FFR, Coronary Flow Reserve (CFR), Index of Microcirculatory Resistance (IMR) and Resistance Reserve Ratio (RRR) in all of them. We calculated RFR retrospectively from the pressure tracings.
Results
Coronary physiology parameters showed a non-normal distribution and are presented as median [IQR]: FFR 0.86 [0.79–0.92]; CFR 2.05 [1.4–2.95]; IMR 20.5 [14–32.55]; RRR 2.5 [1.85–3.63]; RFR 0.897 [0.83–0.94]. Patients with abnormal CFR displayed lower RFR values although FFR was not markedly affected (Table 1). These findings remained irrespective of the clinical scenario at presentation.
61 patients had a CFR lower than 2. Correlation between RFR and FFR was not significantly different in patients with abnormal CFR than in those with normal CFR (0,73 vs 0,88; p=0,067) (Figure 1); however, overall binary agreement between RFR and FFR was worse in patients with a low CFR (69% vs 83%; p=0,047).
48 patients had a high IMR (>25). Linear correlation between RFR and FFR was similar in patients with high and normal IMR (0,81 vs 0,83; p=0,784); likewise, binary concordance showed no significant difference between both groups (77% vs 75%, p=0,78).
The mean difference between RFR and FFR was 0,025. This was only influenced by CFR: patients with a low CFR had a smaller difference than those with a normal CFR (0,012 vs 0,035; p=0,019).
Physiology parameters by CFR group Normal CFR (≥2) Low CFR (<2) P-value FFR 0.88 [0.82–0.93] 0.84 [0.79–0.92] 0.14 RFR 0.91 [0.88–0.95] 0.86 [0.80–0.92] 0.0009 IMR 16.5 [13–27] 25 [16–45.5] 0.002 RRR 3.6 [2.7–4.9] 1.7 [1.3–2.1] <0.0001 Physiological coronary parameters (Median [IQR]) according to CFR.
Correlation between RFR and FFR by CFR
Conclusion
RFR has good overall correlation and concordance with FFR. However, RFR has a lower diagnostic accuracy in patients with a low CFR.

Abstract
Coccidioidomycosis is usually acquired by inhalation of spores of Coccidioides immitis and C. posadasii. The disease ranges from a self-limited acute pneumonia (Valley Fever) to a disseminated disease. We present a 44-year-old healthy male who had patchy hair loss of several months duration resembling discoid lupus. He developed a firm non-scaly red plaque on the right forehead. Initial biopsy showed spongiotic dermatitis, and he was treated with systemic steroids. He then developed forehead and periorbital cellulitis and was treated with systemic antibiotics. A second biopsy showed fungal hyphae, and he was treated with itraconazole 200mg bid for 4months beyond clinical resolution. A year later, he presented with intermittent swelling of the right forehead lesion and worsening of the scalp lesions. A forehead biopsy showed interface dermatitis and negative PAS stain for fungi. Scalp biopsy was highly suggestive of discoid lupus and he was started on plaquenil. Many months later, a third biopsy showed fungal infection, and the culture grew C. immitis. He was treated with itraconazole. Retrospectively, the patient gave a history of Valley fever 6 years back when he was in Arizona, USA.

Abstract
Cell death triggered by photodynamic therapy can occur through different mechanisms: apoptosis, necrosis or autophagy. However, recent studies have demonstrated the existence of other mechanisms with characteristics of both necrosis and apoptosis. These new cell death pathways, collectively termed regulated necrosis, include a variety of processes triggered by different stimuli. In this study, we evaluated the cell death mechanism induced by photodynamic treatments with two photosensitizers, meso-tetrakis (4-carboxyphenyl) porphyrin sodium salt (Na-H2TCPP) and its zinc derivative Na-ZnTCPP, in two human breast epithelial cell lines, a non-tumoral (MCF-10A) and a tumoral one (SKBR-3). Viability assays showed that photodynamic treatments with both photosensitizers induced a reduction in cell viability in a concentration-dependent manner and no dark toxicity was observed. The cell death mechanisms triggered were evaluated by several assays and cell line-dependent results were found. Most SKBR-3 cells died by either necrosis or apoptosis. By contrast, in MCF-10A cells, necrotic cells and another cell population with characteristics of both necrosis and apoptosis were predominant. In this latter population, cell death was PARP-dependent and translocation of AIF to the nucleus was observed in some cells. These characteristics are related with parthanatos, being the first evidence of this type of regulated necrosis in the field of photodynamic therapy.

Abstract
Motivated by experiments on activity in neuronal cultures [ J. Soriano, M. Rodríguez Martínez, T. Tlusty and E. Moses Proc. Natl. Acad. Sci. 105 13758 (2008)], we investigate the percolation transition and critical exponents of spatially embedded Erdős-Rényi networks with degree correlations. In our model networks, nodes are randomly distributed in a two-dimensional spatial domain, and the connection probability depends on Euclidian link length by a power law as well as on the degrees of linked nodes. Generally, spatial constraints lead to higher percolation thresholds in the sense that more links are needed to achieve global connectivity. However, degree correlations favor or do not favor percolation depending on the connectivity rules. We employ two construction methods to introduce degree correlations. In the first one, nodes stay homogeneously distributed and are connected via a distance- and degree-dependent probability. We observe that assortativity in the resulting network leads to a decrease of the percolation threshold. In the second construction methods, nodes are first spatially segregated depending on their degree and afterwards connected with a distance-dependent probability. In this segregated model, we find a threshold increase that accompanies the rising assortativity. Additionally, when the network is constructed in a disassortative way, we observe that this property has little effect on the percolation transition.

Abstract
PURPOSE This prospective observational study assessed the efficacy of bevacizumab in combination with chemotherapy as preoperative treatment to downsize tumours for radical resection in patients with unresectable metastatic colorectal cancer (mCRC). PATIENTS/METHODS Patients with mCRC initially unresectable according to predefined criteria were included. Preoperative treatment consisted of bevacizumab (5 mg/kg) combined with oxaliplatin- or irinotecan-based chemotherapy, which was followed by surgery in patients showing clinical benefit. Resection rate was the primary endpoint. Response rate (RR) and clinical benefit of preoperative chemotherapy, and overall survival (OS) were secondary endpoints. RESULTS A total of 120 eligible patients were included and received preoperative treatment. Chemotherapy was irinotecan-based in 73 (61 %) patients, oxaliplatin-based in 25 (21 %) and 22 (18 %) patients received more than one line. A RR of 30 % and a clinical benefit rate of 73 % were observed with preoperative chemotherapy. Metastatic resection was possible in 61 (51 %) patients. Median OS was 33 months (95 % CI 31-NA months) for patients undergoing surgery, and 15 months (95 % CI 11-25 months) in non-operated patients. Thirty-five patients experienced 59 postoperative complications (morbidity rate 57 %). CONCLUSION Preoperative bevacizumab-based chemotherapy offers a high surgical rescue rate in patients with initially unresectable mCRC.

Abstract
The paper provides a comprehensive perspective of the critical aspects to be taken into account when planning the long-term management of water meters in a utility. In order to facilitate their quick understanding and practical implementation, they have been structured into nine steps. Ranging from an initial audit up to the final periodic meter replacement planning, these steps cover three aspects of the problem - field work, laboratory work and management tasks; and each one is developed in detail paying attention to the particular data needed and noting the practical outcome it will yield.

Abstract
BACKGROUND The association between lung cancer and COPD has not been investigated in the primary care setting. METHOD We determined the recent trends of lung cancer in COPD patients in the UK during the period 1991-2004, by investigating the population aged 45 and over in the General Practice Research Database. RESULTS The annual-incidence rates of lung cancer per 10,000 person-years were at least four-fold higher in patients with prior COPD (increasing from 45 to 64 in men; 29 to 48 in women) compared with the general population (from 10 to 15 in men; 5 to 10 in women). These lung cancer trends had significant annual increases that were similar in men (5%) and in women (5.5%) with prior COPD; in contrast, the annual increases of lung cancer incidence rates in the general population differed by gender, being 4% in men but double in women (8%). The three-year survival for lung cancer patients among those with prior COPD was almost half that of the general population (15% versus 26%; p<0.01) and the highest mortality was observed in men aged 45-64 (83.79 per 100 person-years; 95% CI: 69.66-97.92). CONCLUSION These results support the association of COPD and lung cancer observed in other settings.

Abstract
BACKGROUND Bronchiectasis remains a major public health problem, but factors influencing its natural history are not well characterized. The objective of our study was to explore modifiable and nonmodifiable factors associated with lung function decline in a clinical cohort of patients with stable non-cystic fibrosis (CF) bronchiectasis. METHODS Seventy-six stable adult patients (mean age, 69.9 years; 48.7% men) with bronchiectasis were included. The diagnosis of bronchiectasis was established in all cases by high-resolution CT scanning. Baseline data were collected on clinical history, symptoms, disease extension, treatment, sputum volume, microbiological aspects, laboratory findings, and exacerbations. All patients were invited to attend the clinic every 6 months for 24 months to conduct full spirometry and microbiological analysis of sputum, and to report the number of exacerbations. RESULTS Overall, the group experienced a rate of decline of lung function (FEV1) of 52.7 mL per year. Independent factors associated with an accelerated decline of lung function were chronic colonization with Pseudomonas aeruginosa (PA) [odds ratio (OR), 30.4; 95% confidence interval (CI), 3.8 to 39.4; p=0.005], more frequent severe exacerbations (OR, 6.9; 95% CI, 2.3 to 10.5; p=0.014), and more systemic inflammation (OR, 3.1; 95% CI, 1.9 to 8.9; p=0.023). Regrettably, none of the long-term treatment strategies evaluated, including the use of long-acting inhaled bronchodilators, inhaled or oral steroids, oxygen therapy, secretion clearance maneuvers, or antibiotics had a significant effect on FEV1 decline. CONCLUSION Chronic colonization by PA, severe exacerbations, and systemic inflammation are associated with disease progression in non-CF bronchiectasis.

Abstract
Recent retrospective studies have suggested that use of inhaled corticosteroids (ICS) may improve survival in chronic obstructive pulmonary disease (COPD), particularly when combined with a long-acting beta-agonist (LABA). However, the study methodologies have been questioned, and no study has examined the survival effect of the newer combination ICS/LABA inhalers. The goal of this project was to further examine the relationship between ICS treatment, with or without LABA, and survival in COPD. COPD patients were identified from the administrative databases of four different integrated health care delivery systems. All patients who were diagnosed with COPD between September 1, 2000 and August 31, 2001 and who had at least 3 months treatment with either a combined fluticasone/salmeterol inhaler (FSI, N=866), any ICS used with a LABA (ICS/LABA, N=525), ICS alone (N=742), LABA alone (N=531), or a short-acting bronchodilator alone (SABD, N=1832), were included. Analyses were conducted using three different analysis approaches that adjust for various biases that may affect the results. In the basic Cox proportional hazards models, use of FSI, ICS/LABA, ICS alone, and LABA alone had significant survival benefits as compared to SABD, after adjustment for differences in age, gender, comorbidities, asthma status, and disease severity (HRs 0.61 [0.45-0.83], 0.59 [0.46-0.77], 0.76 [0.61-0.95], 0.75 [0.57-0.98], respectively). Propensity score matching to reduce the clinical differences between the treatment groups versus the SABD reference group found very similar results. Nested case-control analyses, which are based on survival status instead of treatment, continued to show a significant survival benefit for FSI, ICS/LABA, and ICS alone. Treatment with FSI or another ICS with or without LABA is associated with improved survival in COPD. The treatment benefit is reproducible and is robust to application of a number of different analysis techniques designed to adjust for differences in confounding variables and for bias by indication.

Abstract
We report experiments on spontaneous imbibition of a viscous fluid by a model porous medium in the absence of gravity. The average position of the interface satisfies Washburn's law. Scaling of the interface fluctuations suggests a dynamic exponent z approximately 3, indicative of global dynamics driven by capillary forces. The complete set of exponents clearly shows that interfaces are not self-affine, exhibiting distinct local and global scaling, both for time (beta = 0.64 +/- 0.02, beta(*) = 0.33 +/- 0.03) and space (alpha = 1.94 +/- 0.20, alpha(loc) = 0.94 +/- 0.10). These values are compatible with an intrinsic anomalous scaling scenario.

Abstract
Amylomyces rouxii eliminated 85% of initial pentachlorophenol (PCP) at 12.5 mg l(-1) when grown with 0.1 g tyrosine l(-1), but only 55% without tyrosine. Addition of tyrosine in the culture medium increased the monophenolase activity by 1.8-fold. Tyrosinase is thus indicated to be the phenoloxidase involved in PCP degradation by A. rouxii .

Abstract
Exposure to an increasing amount of products in the work environment is leading to new cases of occupational asthma among workers. We report the case of a worker at a pharmaceutical plant who developed occupational rhinitis and bronchial asthma due to HBTU: 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate and TBTU: 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate sensitization, two chemical products widely used in peptide synthesis and coupling. Skin tests (prick test) with HBTU and TBTU solutions in PBS were positive at a concentration of 1 mg/ml. Skin tests with the same solutions in 10 atopic controls yielded a negative result. Nasal challenge tests with these products were positive with HBTU at a concentration of 0.01 mg/ml and TBTU at a concentration of 1 mg/ml. In both cases PNIF (peak nasal inspiratory flow) decreased by more than 60% and severe sneezing and rhinorrhea were induced. Nasal challenge tests performed on 10 atopic controls with TBTU and HBTU at a concentration of 1 mg/ml were negative. We conclude that the patient presents occupational rhinitis and bronchial asthma due to TBTU and HBTU; the operational mechanism is probably immunological IgE-mediated given the positive prick tests and nasal challenge with these products.

Abstract
A single nucleotide polymorphism (-1438 G/A) located 1438 base pairs upstream of the consensus start site of the 5-HT2A receptor gene has been reported. The hypothesis that this gene polymorphism may be a susceptibility factor in bulimia nervosa was explored in a female population of purgative bulimics. Bulimia nervosa patients who have suffered preceding anorexia nervosa episodes formed the so-called previous anorexia nervosa bulimic patient group. At variance with some previous reports, when the frequency distribution of genotypes and alleles was compared in patients and controls, no differences were detected regardless of whether the bulimia nervosa patients had suffered prior anorexia nervosa episodes.

Abstract
The serotonin transporter (5-HTT) gene is a firm candidate to explain eating disorders. In this association study, two different polymorphisms were analysed: a variable number of tandem repeat (VNTR) polymorphism in intron 2 and a deletion/insertion polymorphism (5-HTTLPR) in the promoter region. The hypothesis that these gene polymorphisms may be a susceptibility factor in bulimia nervosa (BN) was explored in a female population of 102 purgative bulimics. BN patients who have suffered preceding anorexia nervosa (AN) episodes formed the so-called previous AN bulimic patient group. In our sample of normal-eater controls and purging type bulimics, regardless of whether or not the BN patients had suffered prior AN episodes, no differences were found considering the frequencies of genotypes, alleles or haplotypes of both polymorphic regions of the 5-HTT gene.

Abstract
There is a strong evidence to suggest the association between breast cancer and diffuse scleroderma, though it is an infrequent occurrence. We describe the clinical and radiological findings in a patient who, over a period of 2 years, was diagnosed initially of diffuse scleroderma, next with right breast cancer and finally with left breast cancer. A review of the literature evidencing the relation between these two pathologies is provided. We suggest that special vigilance for tumoral pathology of the breast should be performed in patients with systemic scleroderma.

Abstract
The kinetic roughening of a stable oil-air interface moving in a Hele-Shaw cell that contains a quenched columnar disorder (tracks) has been studied. A capillary effect is responsible for the dynamic evolution of the resulting rough interface, which exhibits anomalous scaling. The three independent exponents needed to characterize the anomalous scaling are determined experimentally. The anomalous scaling is explained in terms of the initial acceleration and subsequent deceleration of the interface tips in the tracks coupled by mass conservation. A phenomenological model that reproduces the measured global and local exponents is introduced.

Abstract
BACKGROUND There is growing evidence that some cases of chronic urticaria and angioedema are associated with thyroid autoimmunity. We present the case of a 42-year old woman with a two month long evolution of edema in the right hemiface associated with thyroid antibodies. METHODS Skin tests were performed with a standard series of aeroallergens and foods and were negative. Epicutaneous tests were performed with a series of contact allergens with a negative result. The chest X-ray was normal. A complete blood count was performed with ESR, biochemistry study, proteinogram, coagulation, complement, rheumatoid factor, anti-nuclear antibodies, hydatidosis and hepatitis serologies, urine sediment and stool parasitology, which were normal. The TSH was normal and, among the thyroid antibodies, the thyroglobulin ones (492 IU/mL) were positive and the microsomal ones were negative. RESULTS The edema remitted with the 2-month long thyroxin treatment. In spite of the clinical response, and although the thyroglobulin antibodies initially suffered a small decrease, they increased to values which greatly surpassed the initial ones, coinciding with a relapse of the facial edema, so that treatment was re-initiated with thyroxin, and the picture subsided again. CONCLUSIONS Some cases of localized edema can be associated with thyroid antibodies and respond to treatment with thyroxin.
