The effect of arbuscular mycorrhizal fungi on biological activity and biochemical properties of soil under vetch growing conditions in calcareous soils.

Due to soils from arid regions with high lime and low organic matter content, farmers receive low yields along with high costs of agricultural inputs, which causes them to look for a solution. In this context, Arbuscular mycorrhizal fungi (AMF) have great potential to reduce fertilizer use by mediating soil nutrient cycles. However, little is known about studies of AMF inoculum on microbial biomass carbon (C), nitrogen (N), and phosphorus (P) cycling during vetch plant vegetation in calcareous areas. In this study, changes in soil biogeochemical properties related to soil C, N, and P cycling were investigated with five different AMF inoculations under vetch (common Vetch (CV; Vicia sativa L.) and Narbonne Vetch (NV; Vicia narbonensis L.) growing conditions. For the field study, a total of five different mycorrhizae were used in the experiment with the random plots design. AMF inoculation decreased the lime content of the soil, and the highest decrease was observed in NV with Glomus (G.) intraradices + G. constrictum + G. microcarpum inoculation (24.41 %). The highest MBC content was recorded in CV vetch G. intraradices (1176.3 mg C kg-1) and the highest MBN content in NV vetch G. intraradices + G. constrictum + G. microcarpum (1356.9 mg C kg-1). CAT activity of soils was highest in CV vetch G. intraradices (31.43 %) and lowest in NV vetch G. intraradices + G. constrictum + G. microcarpum (72.88 %), urease enzyme activity decreased in all treatments except G. constrictum + Gigaspora sp. and G. mosseae inoculations in CV. The highest DHG activity was detected in GF (15.72 %) AMFs in CV and GI (21.99 %) in NV. APA activity was highest in Glomus constrictum + Gigaspora sp. (23.33 %) in CV and Glomus fasciculatum (10.08 %) in NV. In CV plots, G. intraradices + G. constrictum + G. microcarpum (91.67 %) isolates had the highest and G. intraradices community had the lowest RC% (97.33 %) in mixed mycorrhiza species, while in NV plots G. fasciculatum inoculum had the highest and G. intraradices community had the lowest RC%. This study has important implications for the application of AMF for sustainable agriculture. When the results of the study were evaluated, the most effective AMF isolates in terms of C, N, and P cycles were G. constrictum + G. fasciculatum + Gigaspora sp. in Common vetch variety, and G. intraradices in Narbonne vetch variety.

The Intuitive Eating Scale-2 Adapted for Mexican Pregnant Women: Psychometric Properties and Influence of Sociodemographic Variables.

A weight-inclusive approach to health involves the promotion of intuitive eating, i.e., the individual's ability to be aware of their physiological hunger and satiety cues to determine when and how much to eat, while paying attention to how certain foods affect their body. The second version of the Intuitive Eating Scale (IES-2) evaluates four interrelated traits of intuitive eating: Unconditional Permission to Eat (UPE), Eating for Physical rather than emotional Reasons (EPR), Reliance on internal Hunger/Satiety Cues (RHSC), and Body-Food Choice Congruence (BFCC). In this study, our aim was to evaluate the psychometric properties of a Mexican Spanish adaptation of the IES-2 for pregnant women and examine the relationship between intuitive eating traits and maternal sociodemographic characteristics. A sample of 514 pregnant women answered our IES-2 adaptation and a sociodemographic questionnaire. We determined the quality, validity, and reliability of our adaptation through descriptive measures, frequency distributions, intra-class correlations, and extreme answer group comparison for each item, eliminating those with weak technical properties. We then performed an exploratory principal component analysis and a confirmatory factor analysis. Last, we analyzed the association between intuitive eating and maternal sociodemographic and reproductive variables through correlation tests and multivariable linear regressions. Psychometric tests confirmed the validity and reliability of our IES-2 adaptation, which comprised 18 out of the 23 original items. Notably, both the exploratory and confirmatory factor analyses yielded not four but five factors, due to the EPR subscale splitting in two (the "emotional" and "physical" components of EPR). We attribute this novel finding to the emotional manifestations that naturally accompany pregnancy, which may incline pregnant women to base their eating behaviors more on the emotional than the physical component that would otherwise dominate their EPR trait. Further research is also needed about the UPE subscale during pregnancy, due to item removal and subtle changes in meaning. Finally, the influence of sociodemographic variables on the IES-2 score was extremely low, suggesting that other variables, possibly of a psychological nature, may have greater influence on a pregnant woman's intuitive eating.

ELI: an IoT-aware big data pipeline with data curation and data quality.

The complexity of analysing data from IoT sensors requires the use of Big Data technologies, posing challenges such as data curation and data quality assessment. Not facing both aspects potentially can lead to erroneous decision-making (i.e., processing incorrectly treated data, introducing errors into processes, causing damage or increasing costs). This article presents ELI, an IoT-based Big Data pipeline for developing a data curation process and assessing the usability of data collected by IoT sensors in both offline and online scenarios. We propose the use of a pipeline that integrates data transformation and integration tools and a customisable decision model based on the Decision Model and Notation (DMN) to evaluate the data quality. Our study emphasises the importance of data curation and quality to integrate IoT information by identifying and discarding low-quality data that obstruct meaningful insights and introduce errors in decision making. We evaluated our approach in a smart farm scenario using agricultural humidity and temperature data collected from various types of sensors. Moreover, the proposed model exhibited consistent results in offline and online (stream data) scenarios. In addition, a performance evaluation has been developed, demonstrating its effectiveness. In summary, this article contributes to the development of a usable and effective IoT-based Big Data pipeline with data curation capabilities and assessing data usability in both online and offline scenarios. Additionally, it introduces customisable decision models for measuring data quality across multiple dimensions.

The Emotional Experience of Mexican Women with SARS-CoV-2 during Pregnancy-A Qualitative Study.

Pregnant women have been considered a high-risk group for SARS-CoV-2 infection; the impact of the disease on the health of a mother and her child is still being studied. The emotional impact of the pandemic on pregnant women has been extensively studied. Emotional distress is proposed as a perspective to explain the emotional manifestations in women during this stage as something common rather than pathological. The objective of this study was to explore the emotional experience of women who tested positive for SARS-CoV-2 towards the end of their pregnancy, during the first and second waves of COVID-19 in Mexico. A qualitative study was carried out: 18 pregnant women with COVID-19 were interviewed. A thematic analysis of the data was performed, resulting in 3 main themes and 14 subthemes. The COVID-19-infected mothers-to-be experienced mild to moderate emotional distress. It was more intense for those with comorbidities. This distress was aggravated during obstetrical complications and comorbidities, as well as during COVID-19 and postpartum. The emotional distress was appeased by both the perception of medical care and social support. The emotional distress of pregnant women with COVID-19 requires emotional support to reduce its impact.

A Mexican Spanish Adaptation of the Dutch Eating Behavior Questionnaire: Psychometric Properties and Influence of Sociodemographic Variables in Pregnant Women.

Eating behaviors are complex phenomena, entangling physiological signals of hunger and satiety, food choices, emotional states, and social factors and expectations, as well as food availability and sensory appearance. Evaluating eating behaviors is challenging and must cover different motives. One instrument for such evaluation is the Dutch Eating Behavior Questionnaire (DEBQ), composed of three subscales for exploring emotional eating, external eating, and restrained eating. In this article, we aimed to (1) evaluate the psychometric properties of a Mexican Spanish adaptation of the DEBQ; and (2) explore the associations between the three adapted DEBQ scales and the influence of sociodemographic factors on each of the three eating behaviors in Mexican pregnant women. A sample of 514 pregnant women responded to our adapted version of the DEBQ and a questionnaire about sociodemographic information. We performed an exploratory factor analysis using a principal component analysis with varimax rotation; based on this analysis, we removed items that loaded on two factors and then performed a confirmatory factor analysis. The final version of the adapted DEBQ has 26 items, clearly divided into a three-factor structure and satisfactorily reliable (Cronbach's ⍺ = 0.903). We then performed Spearman bivariate correlations and multivariate linear regression with backward variable selection to test the associations and influence of sociodemographic factors on each of the three eating behaviors evaluated with the DEBQ. In pregnant women, emotional eating (EmoE) had a medium-high correlation with external eating (ExtE) and a low correlation with restrained eating (RestE), while ExtE and RestE showed no association. The three eating behaviors are associated with maternal sociodemographic and reproductive variables, which partly explain their variation, most notably maternal schooling. Our adapted version of the DEBQ is suitable for use with Mexican Spanish-speaking pregnant women. Maternal sociodemographic and reproductive factors have an influence on the variance of eating behaviors during pregnancy.

Map of pain education in Latin America: current state and perspectives.

The Latin American Map of Pain Education initiative has developed steadily in recent years. A recent survey yields important new data on the current state and allows outlining of the next steps to improve pain education in Latin American countries. A survey conducted by Federación Latinoamericana de Asociaciones para el Estudio del Dolor (FEDELAT) with data from 19 Latin American countries showed that a generally observed barrier is the lack of adequately trained pain professionals and the insufficient number of pain centers. There is a need for formal programs of pain education and palliative care in undergraduate and graduate programs. These programs should be accessible not only to physicians but to all types of healthcare professionals involved in the management of pain patients. The article includes some recommendations that will certainly be helpful in improving pain education over the next decade in Latin America.

Cell-free fetal DNA testing performance and fetal fraction estimation are not affected in ART-conceived pregnancies.

STUDY QUESTION: Does ART-based conception influence fetal fraction (FF) estimation and cell-free fetal DNA (cffDNA) testing performance? SUMMARY ANSWER: Mode of conception (ART versus natural) does not impact FF estimation or cffDNA test informativity rates. WHAT IS KNOWN ALREADY: Pregnancies achieved via ART are increasing, and cffDNA testing is displacing traditional prenatal screening methods due to its high sensitivity and specificity and noninvasive nature. However, conflicting data exist on cffDNA testing performance and FF in ART pregnancies compared with natural pregnancies. STUDY DESIGN, SIZE, DURATION: We performed a case-control study that included 21 558 consecutive pregnancies (spontaneous, n = 15 707; ART, n = 5851). ART-conceived pregnancies were stratified into two groups according to oocyte origin. Samples were collected from April 2015 to September 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study included women from different centers worldwide. Blood samples were drawn from the 10th week of gestation onward. Massive parallel whole-genome sequencing was used to analyze cffDNA content in blood plasma. Two different types of technologies (single-end and paired-end) were applied because of analysis technology changes made by the sequencing provider over time. FF was determined using different methods depending on the type of technology used. Cases with an FF <2% or with failure in any quality control metrics were classified as noninformative. An analysis of covariance model was selected to identify which qualitative (sequencing methodology, mode of conception, type (i.e. multiplicity) of gestation and age (women >35 or <35 years old)) and quantitative (gestational age, BMI) variables were predictors of FF value. Multinomial logistic regression was used to evaluate whether the mode of conception impacted cffDNA testing performance. MAIN RESULTS AND THE ROLE OF CHANCE: A univariate t-test demonstrated no significant differences in FF values between ART (median FF = 9.2%) and spontaneous pregnancies (median FF = 9.2%). Also, a multivariate analysis showed that the mode of conception, did not strongly impact the percentage of FF. ART-treated women showed a lower incidence of high-risk cffDNA results compared to women who conceived naturally, specifically for trisomy (T)21 (0.7% versus 1.3%, P = 0.001) and T18 (0.1% versus 0.3%, P = 0.001). A multivariate model stratified by type of aneuploidy suggested that these differences were conditioned by oocyte origin, especially for the T21 risk classification (P < 0.0001). False-positive rates (FPRs) were significantly higher in the ART population, mainly for T13 (P = 0.001) and sexual chromosome aneuploidies (SCAs; P < 0.001). A multivariate model suggested that the differences observed in SCAs were caused by sequencing modality rather than by mode of conception. Likewise, ART-treated women who used their own oocytes had a higher probability of a false positive for T13 (P = 0.004). LIMITATIONS, REASONS FOR CAUTION: Our study lacks follow-up data for low- and high-risk cases of both ART-conceived and naturally conceived pregnancies. Therefore, the results comparing FPR in both populations should be interpreted carefully. Also, collecting information about different ART modalities and regarding preimplantation genetic testing for aneuploidy treatments would help draw definite explanations for the trends observed in this study. WIDER IMPLICATIONS OF THE FINDINGS: This is the first study that demonstrates, with a large sample size, that FF is not influenced by mode of conception, demystifying the notion that patients undergoing ART have a higher probability of noninformative cffDNA testing results. Multivariate models stratified by oocyte origin and type of aneuploidy demonstrated that ART-conceived pregnancies do not have a higher probability of classification as a high-risk pregnancy in prenatal testing. This information is especially valuable to clinicians and genetic counselors when informing patients about the risks and limitations of cffDNA testing in ART pregnancies. STUDY FUNDING/COMPETING INTEREST(S): This study was financially supported by Igenomix Lab S.L.U. All authors declare no conflict of interest. TRIAL REGISTRATION NUMBER: N/A.

Infants prenatally exposed to SARS-CoV-2 show the absence of fidgety movements and are at higher risk for neurological disorders: A comparative study.

Congenital viral infections are believed to damage the developing neonatal brain. However, whether neonates exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) show manifestations of such damage remains unclear. For neurodevelopment evaluation, general movement assessments have been shown to be effective in identifying early indicators of neurological dysfunction, including the absence of fidgety movements. This study compared the early motor repertoire by general movement assessment at three to five months of age in neonates who were or were not prenatally exposed to SARS-CoV-2 to determine whether infants prenatally exposed to SARS-CoV-2 are at risk of developing neurological disorders. Fifty-six infants, including 28 in the exposed group of mothers without vaccination who had no need for intensive care and likely had SARS-CoV-2 infection close to the time of pregnancy resolution and 28 infants in the nonexposed group, were videotaped to compare their detailed early motor repertoires, in which a motor optimality score-revised (MOS-R) was calculated using Prechtl's method by using the chi-square or Mann-Whitney U tests. In the exposed group, 3 (11%) infants showed the absence of fidgety movements with a total MOS-R<14 points, and 3 (11%) other infants showed abnormal fidgety movements. Between groups, atypical body symmetry (p = 0.009) and MOS-R values were significantly lower (Z = -3.08, p = 0.002), with a large size effect (Cohen's d = 0.97). The consequences of this new virus go beyond the health of the pregnant mother, and these consequences in some of the infants in the exposed group are likely not transitory because of the absence of fidgety movements between 3-5 months; thus, these babies are at increased risk of developing a serious neurological disorder.

Soil Water Content Prediction Using Electrical Resistivity Tomography (ERT) in Mediterranean Tree Orchard Soils.

Water scarcity in arid and semiarid regions poses problems for agricultural systems, awakening special interest in the development of deficit irrigation strategies to improve water conservation. Toward this purpose, farmers and technicians must monitor soil water and soluble nutrient contents in real time using simple, rapid and economical techniques through time and space. Thus, this study aimed to achieve the following: (i) create a model that predicts water and soluble nutrient contents in soil profiles using electrical resistivity tomography (ERT); and (ii) apply the model to different woody crops under different irrigation regimes (full irrigation and regulated deficit irrigation (RDI)) to assess the efficiency of the model. Simple nonlinear regression analysis was carried out on water content and on different ion contents using electrical resistivity data as the dependent variable. A predictive model for soil water content was calibrated and validated with the datasets based on exponential decay of a three-parameter equation. Nonetheless, no accurate model was achieved to predict any soluble nutrient. Electrical resistivity images were replaced by soil water images after application of the predictive model for all studied crops. They showed that under RDI situations, soil profiles became drier at depth while plant roots seemed to uptake more water, contributing to reductions in soil water content by the creation of desiccation bulbs. Therefore, the use of ERT combined with application of the validated predictive model could be a sustainable strategy to monitor soil water evolution in soil profiles under irrigated fields, facilitating land irrigation management.

Use of Piptatherum miliaceum to enable the establishment success of Salvia rosmarinus in Technosols developed from pyritic tailings.

With this study we aimed to assess the effect of the prior development of Piptatherum miliaceum (Pm) in a Technosol on the establishment of Salvia rosmarinus (Sr) as a cash crop. An experimental pot was performed with two biochar (BCh) doses (BCh1 and BCh2) mixed with marble waste and pyritic tailings, with and without Pm. After 12 months of Pm growth, the pots with this species were divided into two sets: Sr alone and Sr + Pm. An agricultural soil (AGR) was used as an external control. The results showed that the growth of Sr led to similar shoot biomass to AGR. Sr + Pm reduced shoot biomass by 50%. Total soil organic and recalcitrant C, and total and recalcitrant N showed the highest values in vegetated pots, with no effect of the BCh rate. The decrease in the soil metals availability was related with increases in soil pH. BCh1Sr + Pm treatment showed a microbial community structure more similar to AGR, related to higher fungal and bacterial abundance, enzyme activities and soluble carbon. Thus, growing Sr + Pm seems a suitable strategy to improve soil properties, including microbial abundance, with low translocation of metals. Although the BCh rate did not affect plant growth or soil physicochemical properties, the lowest rate contributed to the growth of soil microorganisms better. The simultaneous growth of Sr + Pm reduced biomass production, and a source of available nutrients is also recommended. Further studies are needed to test this strategy in the field, and to ensure its suitability and a constant biomass production.

OBJECTIVES: To analyze the health-related quality of life (HRQoL) in patients with advanced chronic kidney disease in pre-dialysis and the relationship with the dependency for the instrumental activities of daily living (IADL). MATERIAL AND METHOD: A descriptive and cross-sectional study was carried out in the Nephrology Service of the Reina Sofía University Hospital in Córdoba. It was a non-probability accidental sampling. The following questionnaires were used: KDQOL-SF to analyze HRQoL and Lawton y Brody for IADL dependency. RESULTS: 105 patients on pre-dialysis were studied with an age of 67,8±15,7 years and 35 women (33,3%). With regards to the KDQOL, the most affected dimensions were Changes in health status, Work situation, Burden of kidney disease, General health, Vitality and Physical role. 57.1% of the participants had some degree of dependence for the instrumental activities of daily life. Patients with a higher degree of dependency had worse scores in the dimensions Effects of kidney disease, Work situation, Cognitive function, Sleep, Physical function, Physical role, Pain, Social function and Vitality. CONCLUSIONS: Pre-dialysis patients have a decreased health-related quality of life in the dimensions Changes in health status, Work situation, Burden of kidney disease, General health, Vitality and Physical role. More than half of the participants show some type of dependency to carry out the instrumental activities of daily life

Bioaugmentaton in Technosols created in abandoned pyritic tailings can contribute to enhance soil C sequestration and plant colonization.

Creation of Technosols in combination with phytostabilization may be a sustainable strategy to minimize the environmental and human health hazards derived from mine tailings. Bioaugmentation can facilitate plant establishment and growth for efficient phytostabilization. In order to assess if bioaugmentation can increase soil quality and fertility, decrease metal(loid) mobility and accelerate plant colonization, a one-year field experiment was designed with creation of Technosols in two tailings ponds with different pH (acidic (AT) and neutral (NT)), with addition of marble waste (MaW) and two organic materials (pig manure (PM) and sewage sludge (SS), without or with inoculation of effective microorganisms (EM) at three rates. Results showed that MaW was the main factor responsible for maintaining pH ~7 in AT and ~8 in NT, decreasing salinity, and decreasing the soluble fraction of metals (70-99%). The soluble fraction of As decreased ~45% in AT, related to increases in pH up to neutrality, while increased ~90% in NT with PM due to pH>8 and higher content of organic compounds. The addition of PM and SS significantly increased soil organic C (SOC), nutrient contents and microbial biomass and activity in both tailings, being PM more effective. However, a positive priming effect was observed in NT with SS addition likely due to higher C/N ratio and lack of nutrients. There was a significant effect of EM rate on inorganic C, SOC, N, K and microbial biomass and activity, with higher values as rate increased. Vegetation richness and density directly increased with increasing EM rate. Multivariate analyses showed that the most important properties contributing to increase richness and plant density were microbial biomass and N. Thus, bioaugmentation contributed to soil C sequestration (as organic and inorganic C) and soil fertility, related to high soil microbial biomass and activity, which facilitated an effective colonization of vegetation.

Malestar psicológico en mujeres con embarazo de alto riesgo / Psychological distress in high-risk pregnant women

La experiencia emocional de la mujer con embarazo de alto riesgo ante la maternidad es un tema poco estudiado, a pesar de la importancia que tiene preservar su salud emocional durante este proceso. Esta investigación analizó la experiencia de malestar psicológico en mujeres con embarazo de alto riesgo, según el riesgo médico diagnosticado, su vivencia de la maternidad y el papel que juegan la pareja, familia y redes de apoyo durante la gestación. Se realizó un estudio instrumental de casos múltiples. Se hicieron entrevistas semiestructuradas a 12 mujeres adultas con diagnóstico médico de embarazo de alto riesgo y se formaron tres grupos. Se realizó un análisis de significados de Kvale de los datos obtenidos. Los resultados mostraron que la vivencia de la maternidad y la manifestación de malestar psicológico en estas mujeres era diferente, dependiendo del riesgo médico diagnosticado. Además, podía ser de menor o mayor intensidad debido a la falta de planeación del embarazo, las experiencias obstétricas previas, no tener hijos vivos y contar con el apoyo de la pareja y la familia. Las mujeres con embarazo de alto riesgo vivían la maternidad como una experiencia dolorosa, con mucha angustia y miedo de perder el nuevo embarazo por complicaciones.

The emotional experience of maternity in high-risk pregnant women is a subject that has been seldom studied, despitethe importance of preserving the emotional health of women during this stage. This research analyzed the experience of psychological distress in women with high-risk pregnancy according to the medical risk diagnosed, their experience of maternity and the role of the partner, family and support networks during pregnancy. An instrumental multiple cases study was performed. By semi-structured interviews, we interviewed 12 adults’ women with medical diagnosis of high-risk pregnancy and three groups were formed. A Kvale analysis of meanings was performed on data. The results showed that the experience of motherhood and the manifestation of psychological distress in these women were different depending on the diagnosed medical risk; it may be of lower or higher intensity due to the lack of family planning, previous obstetric experiences, the lack of living children and also the support of the partner and the family. High-risk pregnant women lived mate I ty as a painful experience, with great anxiety and fear of losing the new pregnancy for medical complications.

Sustainable nitrogen fertilisation in sweet pepper: assessing growth and fruit quality and the potential nitrate pollution from different organic manures.

BACKGROUND: The use of organic cultivation with manures does not avoid the risk of high nitrate concentrations if nutrient management is inefficient. So we studied the influence of three organic manures combined or not with additional chemical fertilisers on growth and yield of sweet pepper (Capsicum annuum L.), and on the soil and plant N concentrations. RESULTS: After 3 years of organic cultivation, poultry manure caused the highest soil pollution. The evolution of nitrate and organic matter in soil showed a pattern close to that of plant growth. The addition of mineral fertiliser increased vegetative growth and yield, and a cumulative season effect was observed. In treatments with no additional mineral fertiliser N translocation from leaves to fruits happened. A cumulative effect of seasons on fruit quality and a reduction near to 30% was observed in the first fruit quality category after 3 years. The fruit vitamin C content was reduced by increasing N fertilisation. CONCLUSION: The effects of organic fertiliser on soil and plant growth and yield depended on the type of manure used, its rate, and consecutive crop seasons. Horse manure gave the best combination of agricultural and environmental characteristics and could be used without additional fertigation.

Presence of Stenoponia tripectinata (Tiraboschi, 1902) (Siphonaptera, Ctenophtalmidae) in murine (Rodentia) from the Canary Islands.

This article reports the geographical and host distribution of the flea Stenoponia tripectinata on the Canary Islands. S. tripectinata is widely distributed throughout the Mediterranean and North Africa as a parasite of Muridae rodents. To date, Gran Canaria is the only island of the archipelago where S. tripectinata had been found. In this report, S. tripectinata has appeared parasitizing 116 specimens of Mus musculus out of a total of 660, and only 2 Rattus rattus of 215 captured. All the trapped Muridae hosts found to be parasitized by S. tripectinata came from humid biotopes. The results showed that S. tripectinata is present on all the western Canary Islands and on one of the eastern islands, Gran Canaria, the only island already reported. The detection of S. tripectinata on El Hierro, La Palma, La Gomera and Tenerife represents the first records of this flea species on those Canary Islands.

New species in the Old World: Europe as a frontier in biodiversity exploration, a test bed for 21st century taxonomy.

The number of described species on the planet is about 1.9 million, with ca. 17,000 new species described annually, mostly from the tropics. However, taxonomy is usually described as a science in crisis, lacking manpower and funding, a politically acknowledged problem known as the Taxonomic Impediment. Using data from the Fauna Europaea database and the Zoological Record, we show that contrary to general belief, developed and heavily-studied parts of the world are important reservoirs of unknown species. In Europe, new species of multicellular terrestrial and freshwater animals are being discovered and named at an unprecedented rate: since the 1950s, more than 770 new species are on average described each year from Europe, which add to the 125,000 terrestrial and freshwater multicellular species already known in this region. There is no sign of having reached a plateau that would allow for the assessment of the magnitude of European biodiversity. More remarkably, over 60% of these new species are described by non-professional taxonomists. Amateurs are recognized as an essential part of the workforce in ecology and astronomy, but the magnitude of non-professional taxonomist contributions to alpha-taxonomy has not been fully realized until now. Our results stress the importance of developing a system that better supports and guides this formidable workforce, as we seek to overcome the Taxonomic Impediment and speed up the process of describing the planetary biodiversity before it is too late.

Escala de duelo perinatal: validación en mujeres mexicanas con pérdida gestacional / Perinatal Grief Scale: Validation in Mexican Women with Gestational Loss

La pérdida de un hijo al inicio de la vida constituye uno de los estresores emocionales más intensos que puede experimentar una mujer. La evaluación de este proceso de duelo requiere contar con instrumentos confiables y válidos. El objetivo del presente trabajo fue determinar las características psicométricas de la Perinatal Grief Scale (Escala de Duelo Perinatal, EDP) en una muestra de mujeres mexicanas que habían experimentado pérdidas perinatales. La escala fue traducida, retraducida, piloteada y adaptada, para finalmente aplicarla a 200 mujeres que habían experimentado una o más pérdidas perinatales y que asistían a una clínica especializada. Los datos fueron sometidos a los procedimientos estadísticos usuales de validación (análisis de distribución de frecuencias, comparación de grupos extremos, análisis factorial exploratorio y análisis factorial confirmatorio, así como correlación entre subescalas) y de evaluación de consistencia interna, obteniendo índices adecuados de confiabilidad y validez. La EDP quedó conformada por 27 reactivos, agrupados en cuatro subescalas: duelo activo, depresión, culpa y aceptación. Se discute su utilización en la investigación y en la práctica clínica.

Losing a child at the beginning of life is one of the most intense emotional stressors that may experience a woman. The evaluation of this mourning process requires reliable and valid instruments. This study aimed to determine the psychometric characteristics of the Perinatal Grief Scale (PGS) in a sample of Mexican women who had experienced perinatal loss. The scale was translated, retranslated, tested and adapted to finally be applied to 200 women who had experienced one or more perinatal loss and were attending a clinic. Data were subjected to the usual statistical procedures of validation (analysis of frequency distribution, comparison of extreme groups, exploratory factor analysis and factor analysis confirming, as well as correlation between scales) and evaluation of internal consistency, obtaining appropriate indexes of reliability and validity. The Perinatal Grief Scale (EDP) was formed by 27 items, grouped in four scales: active grief, depression, guilt, and acceptance. Its use in research and clinical practice is discussed.

Real time conductance catheter system based on FPGA.

This paper presents a digital conductance catheter system based on FPGA (Field Programmable Gate Arrays) to measure real time ventricular volumes for experimental use. The system performance is realized in three stages: a) conductance measurements using a well-known set of resistance connected to each catheter section; b) volumes measurements in glass containers of well-known geometry that contain a solution with a resistivity similar to the blood, and c) comparison between the previous analog conductance catheter system and this novel FPGA based system.

Implantable hemodynamic monitors: Can be conductance catheter system successfully implemented?

Successful management of cardiac heart failure requires a multifactorial approaching. It has been suggested that implantable hemodynamic long-term monitoring can improve patient care. This paper presents an analysis of the hemodynamic parameters commonly recorded, the most used implantable devices and their associated clinical trials. Newly implantable miniaturized sensors and devices are revisited. Finally, a newly implantable conductance-catheter based system is presented. The feasibility to realise volume and pressure measurements in the human left ventricular cavity using an implantable conductance-catheter based system is evaluated. It has the advantage to obtain LV signals continuously. In addition, it allows to realise maneuvers such as calibration and LV function by telemetry being avoiding patient hospitalizations. The rapid advances in device monitoring capabilities could change the new paradigm of the heart disease management.
