Abstract
INTRODUCTION Gender equity in urological meetings is pivotal for fostering diversity and inclusivity in the field. This study aims to evaluate the representation of Spanish urologist and regional disparities, and to assess its alignment with the demographic composition of the urological community. MATERIALS AND METHODS All urology meetings organized by the AEU between January 2012 and December 2022 were reviewed, including meeting information and details of the faculty. Additionally, we analysed geographic distribution of speakers across 17 different regions. Gender demographics were obtained disaggregating data by sex and year from the Organización Médica Colegial de España (OMC) and from those urologists affiliated to the AEU. RESULTS Analysing 52 AEU congresses held from 2012 to 2022, encompassing 3,407 speakers, the study found that 95.25% of speakers were from Spain and 89.6% were male speakers. Over the years, there was a positive trend in female speaker representation, increasing by 1.1% annually, slightly lagging the 1.8% annual rise in the number of female urologists in Spain. In specific subfields like functional, transplantation, and oncology sessions, the study revealed a higher representation of women, indicating focused efforts in these areas. Geographically, Madrid, Catalonia and Andalusia exhibited the highest representation. CONCLUSIONS Although there was a positive trend towards an increased participation of female urologists in Spanish urological meetings, it fails to accurately reflect the proportional increase in the number of women entering the urology profession in recent years. This study underscores the importance of ongoing efforts to ensure diverse and balanced representation in urological forum.

Distribution, reactivity and vertical fluxes of methane in the Guadalquivir Estuary (SW Spain). THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 907:167758. [PMID: 37832660 DOI: 10.1016/j.scitotenv.2023.167758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 09/18/2023] [Accepted: 10/10/2023] [Indexed: 10/15/2023]
Abstract
The influence of temperature, salinity, sediment-water-atmosphere exchanges and oxidation rate on the variability of methane (CH4) in the Guadalquivir Estuary has been studied. The database corresponds to 3 intensive samplings carried out in summer (2021 and 2022) and winter (2022). An increase in CH4 concentration towards the interior of the estuary has been observed, more intense during summer (19-371 nmol L-1). The influence of temperature and salinity on the variability of CH4 concentration is negligible, with contributions below 1 nmol L-1. Water-atmosphere fluxes increase inland in summer (28-574 μmol m-2 d-1), being generally higher than in winter (18-80 μmol m-2 d-1). Similarly, benthic fluxes remain relatively constant in winter (10 ± 6 μmol m-2 d-1) and increase inland in summer (7-212 μmol m-2 d-1). In the innermost station of the estuary, with salinities lower than 1, there is a significant increase in benthic fluxes, with values above 9000 μmol m-2 d-1. CH4 oxidation rates increase towards low salinities, being especially high in summer (489 nmol L-1 d-1). Based on the information obtained, CH4 variability in the Guadalquivir Estuary is mainly controlled by water-atmosphere fluxes, benthic fluxes and oxidation in the water column. The uncertainty associated with the quantification of these processes does not allow an adequate assessment of the influence of lateral inputs, although there is experimental evidence of their importance in the Guadalquivir.

Dynamics of CO 2, CH 4, and N 2O in Ria Formosa coastal lagoon (southwestern Iberia) and export to the Gulf of Cadiz. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 906:167094. [PMID: 37734615 DOI: 10.1016/j.scitotenv.2023.167094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 08/16/2023] [Accepted: 09/13/2023] [Indexed: 09/23/2023]
Abstract
A first characterization of greenhouse gases had been carried out to study their role and impact in a productive transitional coastal system of the southern Portugal - Ria Formosa lagoon. To this purpose, the partial pressure of CO2 (pCO2) and the concentration of dissolved CH4 and N2O have been measured. Two surveys were carried out during 2020, at low tide under typical conditions of Spring (March) and end of Summer (October). The samplings sites were distributed along the costal lagoon covering: i) inner areas with strong human impact (influence of different flows of treated wastewater discharges); and ii) main channels in connection with the main inlets to study the exchanges with the ocean. In general, the highest values of the three greenhouse gases were found at the inner studied areas, especially affected by the disposal of treated effluents from wastewater treatment plans, in October. The mean water - atmosphere fluxes of the CO2, CH4 and N2O are positive, showing that the study area acts as a source of these gases to the atmosphere. On the other hand, it was calculated a rough estimation of the three gases globally exported from Ria Formosa to the ocean, through the main six inlets to evaluate the magnitude of the supply of these gases from Ria Formosa to the adjacent ocean. The mean CO2, CH4 and N2O horizontal water fluxes exported from all the inlets of Ria Formosa to the Gulf of Cadiz for both seasons, during low water, are 8.7 ± 3.9 mmol m-2 s-1, 8.0 ± 3.5 μmol m-2 s-1 and 3.2 ± 1.5 μmol m-2 s-1, which corresponds to a mass transport through the inlets section of 0.7 ± 0.7 kg s-1, 0.2 ± 0.2 g s-1 and 0.2 ± 0.3 g s-1 respectively. From these estimates, as expected, the higher mass transport was found at the larger and deeper inlets (Faro-Olhão and Armona).

Greenhouse gas assemblages (CO 2, CH 4 and N 2O) in the continental shelf of the Gulf of Cadiz (SW Iberian Peninsula). THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 898:165474. [PMID: 37463626 DOI: 10.1016/j.scitotenv.2023.165474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 06/12/2023] [Accepted: 07/09/2023] [Indexed: 07/20/2023]
Abstract
This study examines the simultaneous water-atmosphere exchange of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) on the continental shelf of the Gulf of Cadiz, as well as the effect it has in terms of the radiative balance in the atmosphere, between 2014 and 2016. The experimental database consists of new measurements of the spatial and seasonal distribution of CO2 partial pressure (pCO2) and N2O concentration in 2016. pCO2 shows a wide range of variation influenced mainly by seasonal thermal variations (8.0 μatm 0C-1), as well as with the relative intensity of biological activity. There is experimental evidence of a progressive increase of pCO2 over the last 2 decades, with an estimated gradient of 4.2 ± 0.7 μatm y-1. During 2016, the Gulf of Cadiz acted as a slight source of CO2 to the atmosphere, with a mean flux of 0.4 ± 2.2 mmol m-2 d-1. The analysis of concentration variations in the water column shows that nitrification is the main N2O production process in the study area, although in the more coastal zone there are signs of inputs related to continental and sediment contributions, most probably induced by denitrification processes. In 2016, the Gulf of Cadiz acted as a weak sink of atmospheric N2O, with a mean flux of -0.1 ± 0.9 μmol m-2 d-1. From previous studies, performed with a similar methodology, an interannual database (2014-2016) of water-atmosphere fluxes of CO2, CH4 and N2O, normalized to the mean wind speed in the area, has been generated. Considering their respective Global Warming Potential (GWP) a joint greenhouse gasses (GHG) flux, expressed in CO2 equivalents of 0.6 ± 2.0 mmol m-2 d-1, has been estimated, which extended to the area of study indicates an approximate emission of 67.9 Gg CO2 y-1. However, although there is a high uncertainty associated with the spatial, temporal and interannual variations of CO2, CH4 and N2O fluxes in the Gulf of Cadiz, the exchange of greenhouse gasses could be influencing a radiative forcing increase in the atmosphere. When considering the available information on local and global estimates, the uncertainty about the effect of the joint exchange of GHGs to the atmosphere from the coastal seas increases significantly.

Early Dalmatian farmers specialized in sheep husbandry. Sci Rep 2023; 13:10355.

Abstract
The spread of farming in the central and western Mediterranean took place rapidly, linked to the Impressa Ware. The Impressa Ware originated somewhere in the southern Adriatic and spread westwards across the Mediterranean. These early farmers had an economy based on cereal agriculture and caprine husbandry, but there is still little information on how this agropastoral system functioned. This study aims to unravel the farming practices of the early Dalmatian farmers linked to the Impressa culture by using an integrated analysis, combining archaeozoology, palaeoproteomics and stable isotopes, applied to the faunal assemblages of Tinj-Podlivade and Crno Vrilo. The results show: (1) the composition of the flocks was overwhelmingly sheep; (2) sheep exploitation at both sites was similar, focusing on milk and meat; (3) sheep reproduction was concentrated at the beginning of winter, with no reproduction in autumn as in later sites in the western Mediterranean. We conclude that a common animal economy existed at both sites, which could be related to the mobility practiced by these early farming societies throughout the Mediterranean.

Dynamic of CO 2, CH 4 and N 2O in the Guadalquivir estuary. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 805:150193.

Abstract
The concentration of dissolved CH4 and N2O, as well as the partial pressure of CO2 (pCO2) were studied in the Guadalquivir estuary. Samples were taken in March and April 2018 and 2019, under different rainy and tidal conditions. The available database for summer 2017 (Sierra et al., 2020) was included in the interpretation of the factors that determine the variability of these gases in the Guadalquivir estuary. Two different types of samplings were carried out: a longitudinal transect across the river with salinity values close to zero and another one during two consecutive tidal cycles in the mouth of the estuary. The highest concentrations were found in the upper zone of the estuary and during the low tide. This distribution was related to 4 factors: temperature, salinity, exchange with the atmosphere, and biochemical processes together with the river inputs. Temperature is one of the factors that clearly seems to determine the distribution of gases and fluxes, showing the highest values in the upper zone during the summer of 2017. Intense rains cause a dilution effect of the gas in the water column, this provoked, during the season of spring 2018, an increase in the salinity factor in the distribution of gases in the middle zone. High concentrations of the gases have been linked to production processes in the water column, as well as to benthic production and lateral inputs. While the gases concentrations at the mouth presented values close to those of the equilibrium with the atmosphere, the fluxes in the upper zone of the estuary reached average values of 89.6 mmol m-2 d-1, 121.7 μmol m-2 d-1 and 59.9 μmol m-2 d-1 for CO2, CH4 and N2O, respectively. Generally, water-atmosphere fluxes are positive through the whole study, which means that the estuary acts as a source of these gasses to the atmosphere.

Abstract
INTRODUCTION Despite representing a significant number of cases, patients with chronic migraine and daily headache are frequently excluded from large therapeutic clinical trials. These individuals have hardly been studied and could have specific properties. Development. A third of patients with chronic migraine may suffer from headaches every day, representing up to 1.7 - 3.3% of patients in a general neurology consultation. These patients are excluded from most studies, so little information is available. They may have a longer lasting migraine and different response to treatment. Patients with chronic migraine and daily headache may have complex pathophysiological mechanisms that favor the daily manifestation of migraine. The management of these patients is a therapeutic challenge, and OnabotulinumtoxinA may be useful. CONCLUSION Patients with chronic migraine and daily headache may have specific clinical and therapeutic characteristics. New studies could lead to differentiate it from chronic migraine.

Abstract
Omega-3 fatty acids (n-3 PUFAs) are essential for the functional maturation of the brain. Westernization of dietary habits in both developed and developing countries is accompanied by a progressive reduction in dietary intake of n-3 PUFAs. Low maternal intake of n-3 PUFAs has been linked to neurodevelopmental diseases in Humans. However, the n-3 PUFAs deficiency-mediated mechanisms affecting the development of the central nervous system are poorly understood. Active microglial engulfment of synapses regulates brain development. Impaired synaptic pruning is associated with several neurodevelopmental disorders. Here, we identify a molecular mechanism for detrimental effects of low maternal n-3 PUFA intake on hippocampal development in mice. Our results show that maternal dietary n-3 PUFA deficiency increases microglia-mediated phagocytosis of synaptic elements in the rodent developing hippocampus, partly through the activation of 12/15-lipoxygenase (LOX)/12-HETE signaling, altering neuronal morphology and affecting cognitive performance of the offspring. These findings provide a mechanistic insight into neurodevelopmental defects caused by maternal n-3 PUFAs dietary deficiency.

Abstract
OBJECTIVE We address the hypothesis that the extraordinary sandstorm occurred on 22-24 February 2020 might have a role in the different cumulated incidence of COVID-19 cases between the islands of Tenerife and Gran Canaria, since it obliged to reduce significantly air traffic and forced to suspend all major carnival street events in all most locations. METHOD We performed a retrospective analysis of COVID-19 cases as to 1 April 2020 according to symptoms onset, weather-related data and Carnival events in Tenerife and Gran Canaria. RESULTS The sandstorm occurred on February 22-24, 2020, forced air traffic to close, reducing the influx of tourists to the Canary Islands and suspending carnival events in most places, except in Santa Cruz de Tenerife. Cumulated incidence as to 1 April was 132.81/100,000 in Tenerife, and 56.04/100,000 in Gran Canaria. CONCLUSIONS The suspension of Carnival events due to the sandstorm in the Canary Islands contributed to reduce differently the SARS-CoV-2 spread in Tenerife and Gran Canaria.

Abstract
Background:Systemic lupus erythematosus (SLE) clinical manifestations, and their severity, vary according to age, ethnicity and socioeconomic status. Both Hispanic and Afro-Americans have a higher incidence and more sever presentation when compared to Caucasian patients with SLEObjectives:To analyze clinical and immunological characteristics associated with time to severe renal involvement in patients with Systemic Lupus Erythematous in a Colombian cohort followed for one year, between January 2015 and December 2018Methods:Retrospective follow-up study based in clinical records. Patients with SLE diagnosis that fulfilled either 1987 American College of Rheumatology Classification Criteria for SLE or 2011 Systemic Lupus International Collaborating Clinics (SLICC) classification criteria for SLE. We included patients with diagnosis of lupus nephritis according to Wallace and Dubois criteria. Patients who did not have at least two follow-up measurements or had a cause of nephritis other than lupus were excluded. The main outcome was defined as time from diagnosis to sever renal involvement defined as creatinine clearance ≤50 ml/min, 24-hour proteinuria ≥3.5 grams o end stage renal disease.We analyzed clinical and immunological characteristics. Descriptive statistical analyses of participant data during the first evaluation are reported as frequencies and percentages for categorical variables, and as medians and interquartile ranges (IQR) for quantitative variables. Age and sex adjusted survival functions and Hazard ratios (HR) with 95% confidence intervals and p-values were estimated using parametric Weibull models por interval-censored data. P values < 0.05 were considered statistically significantResults:548 patients were analyzed: 67 were left-censored as they presented renal involvement at entry, 6 were interval censored as outcome occurred between study visits, and 475 were right-censored as involvement was not registered during follow-up. 529 (96.5%) patients were female, median age at entry was 46 (IQR = 23) and median age to diagnosis was 29.5 (IQR = 20.6). 67% were mestizo, 13% Caucasian and 0.3% Afro-Colombian. Age and sex adjusted variables associated with time to severe lupus nephritis were high blood pressure HR = 3.5 (95%CI 2.2-5.6; p-value <0.001) and Anti-RO (per unit increase) HR = 1.002 (95%CI 1.001-1.004; p-value = 0.04). Figure 1 shows age and sex adjusted survival function.Conclusion:In our cohort the appearance of severe lupus nephritis occurs in less than 15% of patients at 10 years.

Abstract
Background:Systemic lupus erythematosus is a systemic disease characterized by a compromise of vital organs. The autoimmune activity has been linked to accelerated endothelial damage and increased cardiovascular risk and its outcomes such as heart attack, stroke, and peripheral arterial disease(1). Patients with Lupic nephritis have been characterized by requiring aggressive immunosuppressive therapies apart from prolonged and progressive use of corticosteroids, what you have shown can accelerate these outcomes(2). Other factors such as secondary arterial hypertension, dyslipidemia among others are factors to consider (3).Objectives:To analyze clinical and immunological characteristics associated with time to severe renal involvement in patients with Systemic Lupus Erythematous in a Colombian cohort followed for one year, between January 2015 and December 2018.Methods:Retrospective follow-up study based on clinical records of patients with SLE diagnosis that fulfilled either 1987 American College of Rheumatology Classification Criteria for SLE or 2011 Systemic Lupus International Collaborating Clinics (SLICC) classification criteria for SLE. Patients with cardiovascular disease outcomes such as angina, acute myocardial infarction, stroke, transient cerebral ischemia and chronic arterial occlusive disease were included. Patients who did not have at least two follow-up measurements or had structural heart disease, valvulopathies, arrhythmias, myocarditis, pericarditis were excluded. The main outcome was defined as the time from diagnosis to cardiovascular diseases.Clinical and immunological characteristics were analyzed. Descriptive statistical analyses of participant data during the first evaluation are reported as frequencies and percentages for categorical variables, and as medians and interquartile ranges for quantitative variables. Age and sex adjusted survival functions and Hazard Ratios (HR) with 95% confidence intervals and p-values were estimated using parametric Weibull models for interval-censored data. P values < 0.05 were considered statistically significantResults:547 patients were analyzed: 29 were left-censored as they presented renal involvement at entry, 22 were interval censored as outcome occurred between study visits, and 496 were right-censored as involvement was not registered during follow-up. 528 (96.5%) patients were female, median age at entry was 46 (IQR = 23) and median age to diagnosis was 29.4 (IQR = 20.9). Statistically significant age and sex adjusted variables were High Blood Pressure (HBP) HR = 2.0 (95%CI 1.1-3.6; p-value <0.018) and cumulative prednisolone dose (>10 gr vs <2 gr) HR = 2.4 (95%CI 1. 1-5.1; p-value = 0.023). Figure 1 shows the age and sex adjusted survival function for HBPConclusion:HBP and cumulative steroid doses accelerate the onset of cardiovascular diseases in patients with lupus more than two times. Maintaining blood pressure in goals and performing early clearance of glucocorticoids could improve outcomes in these patients who are already considered a high cardiovascular riskReferences:[1]Hans-Joachim Anders, Ramesh Saxena, Ming-Hui Zhao.

Abstract
Iron is very important element for functioning of the brain. Its concentration changes with aging the brain or during disease. The aim of our work was the histological examination of content of ferritin and free iron (unbound) in brain cortex in association with Aβ plaques from their earliest stages of accumulation in amyloid plaque forming APP/PS1 transgenic mice. Light microscopy revealed the onset of plaques formation at 8-monthage. Detectable traces of free iron and no ferritin were found around plaques at this age, while the rate of their accumulation in and around Aβ plaques was elevated at 13 months of age. Ferritin accumulated mainly on the edge of Aβ plaques, while the smaller amount of free iron was observed in the plaque-free tissue, as well as in and around Aβ plaques. We conclude that free iron and ferritin accumulation follows the amyloid plaques formation. Quantification of cortical iron and ferritin content can be an important marker in the diagnosis of Alzheimer’s disease.

Distribution of N 2O in the eastern shelf of the Gulf of Cadiz (SW Iberian Peninsula). THE SCIENCE OF THE TOTAL ENVIRONMENT 2017; 593-594:796-808. [PMID: 28366870 DOI: 10.1016/j.scitotenv.2017.03.189] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2017] [Revised: 03/03/2017] [Accepted: 03/21/2017] [Indexed: 06/07/2023]
Abstract
Distribution of N2O has been determined in eight cruises along three transects (Guadalquivir, Sancti Petri and Trafalgar) in the Gulf of Cadiz, during 2014 and 2015. The mean N2O value for this area was 10.0±0.9nM, with large spatial and temporal variations. Stratification in the water column has been observed; the concentration of this gas increases with the depth, because of the presence of the Eastern North Atlantic Central Water (ENACW) and the Mediterranean Outflow Waters (MOW). The N2O production measured in this study is mainly due to nitrification. N2O yields from nitrification were estimated from the linear correlation of the excess of N2O (ΔN2O) with Apparent Oxygen Utilization (AOU) and nitrate (NO3-), with values of their slopes ranged between 0.010 and 0.021% and 0.017-0.025% respectively. There is an onshore - offshore gradient of N2O; the highest values were found at the shallower stations, indicating coastal input and benthic remineralization. The seawater-air flux of N2O is affected by several variables (temperature, AOU and NO3-), and the average flux calculated is 2.7±2.0μmolm-2d-1. The fluxes show a decrease with increasing distance from the coast, and with proximity to the Strait of Gibraltar. The study area behaves as a source of N2O to the atmosphere, with a global emission of 0.18Ggyear-1.

Abstract
Methane (CH4) concentrations were measured along three sections of the eastern Gulf of Cadiz (designated "Guadalquivir", "Sancti Petri" and "Trafalgar") during eight cruises in 2014 and 2015. The concentration of CH4 varied from 3.6 to 19.7nmolkg-1 (CH4 saturation percent of 122 and 916%), showing seasonal variation. The highest values were found in December 2014 and November 2015. In most of the sampling area the highest concentration of CH4 was found in subsurface waters at depths close to the thermocline, and in the bottom waters near the coast. The seawater-air flux of CH4 ranged between 0.8 and 59.7μmolm-2d-1, showing seasonal variation in function of the temperature of the surface water. In the "Guadalquivir" and "Sancti Petri" sections, the CH4 fluxes increased with proximity to the coast; this may be a result of continental inputs and CH4 emissions from sediments. The whole study area behaves as a source of CH4 to the atmosphere with mean values of 0.5 and 0.6GgCH4yr-1 in 2014 and 2015, respectively.

Abstract
Inhibitors of the mechanistic target of rapamycin (mTOR) are currently used to treat advanced metastatic breast cancer. However, whether an aggressive phenotype is sustained through adaptation or resistance to mTOR inhibition remains unknown. Here, complementary studies in human tumors, cancer models and cell lines reveal transcriptional reprogramming that supports metastasis in response to mTOR inhibition. This cancer feature is driven by EVI1 and SOX9. EVI1 functionally cooperates with and positively regulates SOX9, and promotes the transcriptional upregulation of key mTOR pathway components (REHB and RAPTOR) and of lung metastasis mediators (FSCN1 and SPARC). The expression of EVI1 and SOX9 is associated with stem cell-like and metastasis signatures, and their depletion impairs the metastatic potential of breast cancer cells. These results establish the mechanistic link between resistance to mTOR inhibition and cancer metastatic potential, thus enhancing our understanding of mTOR targeting failure.

Abstract
This study presents the first insights into the genetic diversity and structure of the American donkey metapopulation. The primary objectives were to detect the main structural features underlying variability among American donkey populations, identify boundaries between differentiated gene pools, and draw the main colonization pathways since the introduction of donkeys into America in the 15th century. A panel of 14 microsatellite markers was applied for genotyping 350 American donkeys from 13 countries. The genetic structure of this metapopulation was analysed using descriptive statistics and Bayesian model-based methods. These populations were then compared to a database containing information on 476 individuals from 11 European breeds to identify the most likely ancestral donor populations. Results showed the presence of two distinct genetic pools, with confluence of the two in Colombia. The southern pool showed a unique genetic signature subsequent to an older founder event, but lacked any significant influence of modern gene flow from Europe. The northern pool, conversely, may have retained more ancestral polymorphisms and/or have experienced modern gene flow from Spanish breeds. The Andalusian and, to a lesser extent, the Catalan breeds have left a more pronounced footprint in some of the American donkey populations analysed.

Abstract
Brain Functional Connectivity (FC) quantifies statistical dependencies between areas of the brain. FC has been widely used to address altered function of brain circuits in control conditions compared to different pathological states, including epilepsy, a major neurological disorder. However, FC also has the as yet unexplored potential to help us understand the pathological transformation of the brain circuitry. Our hypothesis is that FC can differentiate global brain interactions across a time-scale of days. To this end, we present a case report study based on a mouse model for epilepsy and analyze longitudinal intracranial electroencephalography data of epilepsy to calculate FC changes from the initial insult (status epilepticus) and over the latent period, when epileptogenic networks emerge, and at chronic epilepsy, when unprovoked seizures occur as spontaneous events. We found that the overall network FC at low frequency bands decreased immediately after status epilepticus was provoked, and increased monotonously later on during the latent period. Overall, our results demonstrate the capacity of FC to address longitudinal variations of brain connectivity across the establishment of pathological states.

Anthropogenic effects on greenhouse gas (CH4 and N2O) emissions in the Guadalete River Estuary (SW Spain). THE SCIENCE OF THE TOTAL ENVIRONMENT 2015; 503-504:179-189.

Abstract
Coastal areas are subject to a great anthropogenic pressure because more than half of the world's population lives in its vicinity causing organic matter inputs, which intensifies greenhouse gas emissions into the atmosphere. Dissolved concentrations of CH4 and N2O have been measured seasonally during 2013 in the Guadalete River Estuary, which flows into the Cadiz Bay (southwestern Spanish coast). It has been intensely contaminated since 1970. Currently it receives wastewater effluents from cities and direct discharges from nearby agriculture crop. Eight sampling stations have been established along 18 km of the estuary. CH4 and N2O were measured using a gas chromatograph connected to an equilibration system. Additional parameters such as organic matter, dissolved oxygen, nutrients and chlorophyll were determinate as well, in order to understand the relationship between physicochemical and biological processes. Gas concentrations increased from the River mouth toward the inner part, closer to the wastewater treatment plant discharge. Values varied widely within 21.8 and 3483.4 nM for CH4 and between 9.7 and 147.6 nM for N2O. Greenhouse gas seasonal variations were large influenced by the precipitation regime, masking the temperature influence. The Guadatete Estuary acted as a greenhouse gas source along the year, with mean fluxes of 495.7 μmol m(-2)d(-1) and 92.8 μmol m(-2)d(-1) for CH4 and N2O, respectively.

Abstract
AbstractObjectives:To describe the epidemiology of methicillin-resistantStaphylococcus aureus(MRSA) at a university hospital in Tenerife, Canary Islands, during a 40-month period and to evaluate the effectiveness of the application of control measures.Design:Laboratory-based surveillance, medical charts and microbiological records review, and characterization of strains by pulsed-field gel electrophoresis (PFGE) were used to describe the epidemiology. Infection control practices were introduced as an intervention.Setting:A 650-bed, tertiary-care university hospital.Subjects:Patients with clinical and nasal isolates of MRSA and colonized staff members.Results:The rate of nosocomial MRSA infections was 32.5% for 1997, 17.9% for 1998, 14.5% for 1999, and 25.6% during the first 4 months of 2000. The major sites of isolation for nosocomial MRSA infection included surgical wounds (25%) and the lower respiratory tract (24%). Intensive care units and surgical specialties had more frequent MRSA cases. Characteristics associated with nosocomial MRSA isolates included prior use of intensive antibiotic therapy, prolonged hospital stays, major underlying illness, invasive procedures, and older age. PFGE type A (subtype A1) was the strain most frequently found and the only PFGE type involved in clusters.Conclusions:Surveillance cultures and contact droplet precautions were followed by decreased rates for 2 years. Nevertheless, the spread of PFGE subtype Al to many different areas of the hospital and the increase in incidence during the first third of 2000 indicates either that surveillance cultures were not used widely enough or that compliance with isolation measures was suboptimal.

Abstract
AbstractObjective:To analyze the efficacy of periodically changing ventilator circuits for decreasing the rate of ventilator-associated pneumonia when a heat and moisture exchanger (HME) is used for humidification. The Centers for Disease Control and Prevention recommended not changing the circuits periodically.Design:Randomized, controlled trial conducted between April 2001 and August 2002.Setting:A 24-bed, medical–surgical intensive care unit in a 650-bed, tertiary-care hospital.Patients:All patients requiring mechanical ventilation during more than 72 hours from April 2001 to August 2002.Interventions:Patients were randomized into two groups: (1) ventilation with change of ventilator circuits every 48 hours and (2) ventilation with no change of circuits. Throat swabs were taken on admission and twice weekly until discharge to classify pneumonia as endogenous or exogenous.Results:Three hundred four patients (143 from group 1 and 161 from group 2) with similar characteristics (age, gender, Acute Physiology and Chronic Health Evaluation II score, diagnostic group, and mortality) were analyzed. There was no significant difference in the rate of pneumonia between the groups (23.1% vs 23.0% and 15.5 vs 14.8 per 1,000 ventilator-days). There was no significant difference in the incidence of exogenous pneumonia per 1,000 days of mechanical ventilation (1.71 vs 1.25). There was no difference in the distribution of microorganisms causing pneumonia.Conclusions:Circuit change using an HME for humidification does not decrease pneumonia and represents an unnecessary cost.

Abstract
Breast cancer represents the second most frequent etiology of brain metastasis (BM). It is estimated that 10–30 % of patients with breast cancer are diagnosed with BM. Breast cancer BM are increasing due to the aging population, detection of subclinical disease, and better control of systemic disease. BM is a major cause of morbidity and mortality affecting neurocognition, speech, coordination, behavior, and quality of life. The therapy of BM remains controversial regarding use and timing of surgical resection, application of whole-brain radiotherapy, stereotactic radiosurgery and systemic drugs in patients with particular tumor subtypes. Despite numerous trials, the range of interpretation of these has resulted in differing treatment perspectives. This paper is a review of the state of the art and a multidisciplinary guideline on strategies to improve the therapeutic index in this situation.

Abstract
A summer episode was modeled to address the expected response of ambient air O3 to hypothetical emission control scenarios in northeastern Mexico, and in particular in the Monterrey Metropolitan Area (MMA). This region is of interest because the MMA holds one of the worst air quality problems in the country and levels of air pollutants in the rest of northeastern Mexico are starting to be a concern. The MM5-SMOKE-CMAQ platform was used to conduct the numerical experiments. Twenty-four control scenarios were evaluated, combining the level of emission controls of O3 precursors (NO(x) and volatile organic compounds [VOCs]) from 0% to 50%. For the MMA, VOC-only controls result in the best option to reduce O3 concentrations, though the benefit is limited to the urban core. This same strategy results in negligible benefits for the rest of northeastern Mexico. NO(x) controls result in an increase in O3 concentration within the MMA of up to 20 ppbv and a decrease at downwind locations of up to 11 ppbv, with respect to the base-case scenario. Indicator ratios were also used to probe for NO(x)-sensitive and VOC-sensitive areas. Locations with an important influence of NO(x) point sources (i.e., Monclova and Nava/Acuña) are quite sensitive to changes in NO(x) emissions. Border cities in the Rio Bravo/Grande Valley tend to be marginally NO(x)-sensitive. Overall, the MMA seems to be dominated by a VOC-sensitive regime, while the rest of the region would tend to have a NO(x)-sensitive response. The results obtained serve to expand the current knowledge on the chemical regimes that dominate this region (VOC- or NO(x)-sensitive), and thus could help guide public policies related to emission regional control strategies.

Abstract
Colonization surface antigens (CSs) represent key virulence-associated factors of enterotoxigenic Escherichia coli (ETEC) strains. They are required for gut colonization, the first step of the diarrhoeal disease process induced by these bacteria. One of the most prevalent CSs is CS21, or longus, a type IV pili associated with bacterial self-aggregation, protection against environmental stresses, biofilm formation and adherence to epithelial cell lines. The objectives of this study were to assess the role of CS21 in adherence to primary intestinal epithelial cells and to determine if CS21 contributes to the pathogenesis of ETEC infection in vivo. We evaluated adherence of a CS21-expressing wild-type ETEC strain and an isogenic CS21-mutant strain to pig-derived intestinal cell lines. To determine the role of CS21 in pathogenesis we used the above ETEC strains in a neonatal mice challenge infection model to assess mortality. Quantitative adherence assays confirmed that ETEC adheres to primary intestinal epithelial cells lines in a CS21-dependent manner. In addition, the CS21-mediated ETEC adherence to cells was specific as purified LngA protein, the CS21 major subunit, competed for binding with the CS21-expressing ETEC while specific anti-LngA antibodies blocked adhesion to intestinal cells. Neonatal DBA/2 mice died after intra-stomach administration of CS21-expressing strains while lack of CS21 expression drastically reduced the virulence of the wild-type ETEC strain in this animal model. Collectively these results further support the role of CS21 during ETEC infection and add new evidence on its in vivo relevance in pathogenesis.

Abstract
OBJECTIVE to evaluate health personnel perceptions about medical order entry systems concerning the effect on workflow, medication errors risk and assessment of its potential advantages. MATERIAL AND METHODS A cross-section opinion interview was conducted in a tertiary care hospital. Questionnaire consisted of three sections: perception of its effect on workflow, influence on medication error risk and assessment of potential advantages. We also asked them to assess drawbacks and provide suggestions about this prescription system. RESULTS 76 health professionals were interviewed (58 physicians, 9 pharmacists and 9 nurses). They were satisfied mainly due to decrease the workload (85.5%; IC 95%: 75.58-92.55). They thought that the main characteristics that contribute to reduce medication errors are clinical decision supports related to predefined aspects which the program provided by default. Among potential benefits of medical order entry systems, legibility and warnings triggered by the program (98.7%; IC 95%: 92.90-99.97 and 97,4%; IC 95%: 90.81-99.68 respectively) were the most valuable. High technology dependence, IT failures and lack of infrastructure and medication therapy discontinuities at times of transition between different hospitals' units were the main drawbacks considered. The most repeated suggestion was related to the improvement of links between other health informatics applications used in the hospital. CONCLUSION health personnel were highly satisfied with the CPOE system, which is considered to be effective and safe. Technology dependence and IT failures were the main disadvantages reported. According to them, a greater coordination and unification of all software applications available in the hospital would be desirable.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) strains belonging to sequence type (ST) 398 are being reported with increasing frequency in Europe and other countries. This MRSA type has been isolated from colonized and infected animals and humans. The aim of this study was to determine the prevalence of nasal MRSA carriage in pigs and pig workers. A total of 300 pigs from 15 different farms were sampled in the slaughterhouse of Tenerife. A total of 54 pig workers were screened for MRSA: 20 belonged to farms whose pigs had been sampled and 34 to the slaughterhouse. The percentage of positive samples of MRSA in pigs was 85.7%. The overall prevalence of nasal MRSA carriage in pig workers was 9.3%. All MRSA isolates from pigs and humans belonged to one clonal group showing multilocus sequence type (MLST) 398. Two types of Staphylococcal Chromosome Cassette (SCCmec) were found, IV and V. In conclusion, the prevalence of MRSA in nasal samples from pigs and pig workers in Tenerife was high. We therefore consider it essential to deepen epidemiological study of this strain of animal origin, as well as to increase surveillance and control measures at all stages of the food chain.

Rifampicin-miconazole-impregnated catheters save cost in jugular venous sites with tracheostomy. Eur J Clin Microbiol Infect Dis 2011; 31:1833-6. [PMID: 22187350 DOI: 10.1007/s10096-011-1508-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2011] [Accepted: 12/02/2011] [Indexed: 01/13/2023]
Abstract
Antimicrobial-impregnated catheters are more expensive than standard catheters (S-C). A higher incidence of catheter-related bloodstream infection (CRBSI) has been found in jugular venous access with tracheostomy than without tracheostomy. The objective of this study was to determine central venous catheter (CVC)-related costs (considering only the cost of the CVC, diagnosis of CRBSI, and antimicrobial agents used to treat CRBSI) using rifampicin-miconazole-impregnated catheters (RM-C) or S-C in jugular venous access with tracheostomy. We performed a retrospective cohort study of patients admitted to the intensive care unit (ICU) with tracheostomy who received one or more jugular venous catheters. RM-C showed a lower incidence of CRBSI compared with S-C (0 vs. 20.16 CRBSI episodes/1,000 catheter-days; odds ratio=0.05; 95% confidence interval=0.001-0.32; p<0.001) and lower CVC-related costs (including the cost of the CVC, diagnosis, and treatment of CRBSI) (<euro>11.46 ± 6.25 vs. <euro>38.11 ± 77.25; p<0.001) in jugular venous access with tracheostomy. The use of RM-C could reduce CVC-related costs in jugular venous access with tracheostomy. The results of our study may contribute to clinical decision-making and selection of those patients who could benefit from the use of antimicrobial-impregnated catheters.

Lower associated costs using rifampicin-miconazole‒impregnated catheters compared with standard catheters. Am J Infect Control 2011; 39:895-7. [PMID: 21741122 DOI: 10.1016/j.ajic.2011.01.018] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2010] [Revised: 01/27/2011] [Accepted: 01/30/2011] [Indexed: 01/08/2023]
Abstract
Previous cost-effectiveness analyses found that antibiotic-impregnated catheters decrease the incidence of catheter-related bloodstream infection (CRBSI) as well as the costs related to central venous catheter (CVC) use, including increased hospital length of stay. The effect varied greatly among the studies, however. In this retrospective cohort study, compared with standard catheters, the use of rifampicin-miconazole-impregnated catheters was associated with lower CRBSI incidence and immediate CVC-related costs (taking into account only the costs of CVC, diagnosis, and treatment of CRBSI) (P < .001). Our data indicate that the use of rifampicin-miconazole-impregnated catheters can save associated costs.

Measurement of body temperature in adult patients: comparative study of accuracy, reliability and validity of different devices. Int J Nurs Stud 2010; 48:872-80. [PMID: 21145551 DOI: 10.1016/j.ijnurstu.2010.11.003] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2010] [Revised: 11/02/2010] [Accepted: 11/14/2010] [Indexed: 11/26/2022]
Abstract
BACKGROUND AND AIMS We compared a range of alternative devices with core body temperature measured at the pulmonary artery to identify the most valid and reliable instrument for measuring temperature in routine conditions in health services. METHODS 201 patients from the intensive care unit of the Candelaria University Hospital, Canary Islands, admitted to hospital between April 2006 and July 2007. All patients (or their families) gave informed consent. Readings from gallium-in-glass, reactive strip and digital in axilla, infra-red ear and frontal thermometers were compared with the pulmonary artery core temperature simultaneously. External factors suspected of having an influence on the differences were explored. The cut-off point readings for each thermometer were fixed for the maximum negative predictive value in comparison with the core temperature. The validity, reliability, accuracy, external influence, the waste they generated, ease of use, speed, durability, security, comfort and cost of each thermometer was evaluated. An ad hoc overall valuation score was obtained from these parameters for each instrument. RESULTS For an error of ± 0.2°C and concordance with respect to fever, the gallium-in-glass thermometer gave the best results. The largest area under the receiver operating characteristic (ROC) curve is obtained by the digital axillar thermometer with probe (0.988 ± 0.007). The minimum difference between readings was given by the infrared ear thermometer, in comparison with the core temperature (-0.1 ± 0.3°C). Age, weight, level of conscience, male sex, environmental temperature and vaso-constrictor medication increases the difference in the readings and fever treatment reduces it, although this is not the same for all thermometers. The compact digital axillar thermometer and the digital thermometer with probe obtained the highest overall valuation score. CONCLUSION If we only evaluate the aspects of validity, reliability, accuracy and external influence, the best thermometer would be the gallium-in-glass after 12 min. The gallium-in-glass thermometer is less accurate after only 5 min in comparison with the reading taken after being placed for 12 min. If we add the evaluation of waste production, ease-of-use, speed, durability, security, patient comfort and costs, the thermometers that obtain the highest score are the compact digital and digital with probe in right axilla.
