From this point of view, the design and management of irrigation districts can be evaluated by monitoring the soil salinity. There are few cases in the world where comparisons can be undertaken from ‘historic’ data sets for extents other than individual plots. We demonstrate a monitoring procedure using electromagnetic induction (EMI) survey in an irrigated district in Spain. This district is the only one having an established soil salinity baseline. The EMI data acquired at the same plots were converted to soil electrical conductivity by calibrating with augered soil samples. The presented calibrations improve the baseline for future comparisons and for the treatment and understanding of new acquisitions of field data in next surveys. A shortcoming inherent to destructive soil sampling is its potential for biasing effects on long-term monitoring of soil salinity by means of GPS or other means of accurate localization and relocalization of soil sampling, the herein called “localization paradox”, rarely treated in scientific papers. The localization paradox is relevant for any variable soil property requiring repeated sampling. This issue is discussed, and a way for its overcoming by using EMI readings displaced from the augering is presented. EMI needs calibration with a reduced number of soil samples analyzed in the lab.

To be able to answer the present demands of the nursing profession, the teaching must interrelate the different roles
that are developed in daily practice, gaining experience in the learning process to be able to improve the quality in
nursing care. To achieve this goal, problem based learning is important. It is intended that the students will be able to
manage themselves in their professional life in the most natural way, departing from a clear and deep idea of evidence
based practice. For this purpose, clinical cases were designed with goals that made necessary the integration of
knowledge, aptitudes and values, with different stages to be developed in a predetermined time.
Also we designed a teaching strategy to allow the student to incorporate the scientific knowledge supporting the care
teaching practice, to approximate theory and practice. It is intended that the students will look for an answer based on
the best scientific evidence available, to take a decision regarding patient care.
The goals of the study are:
- To holistically evaluate learning based on the simulation of cases.
- To evaluate how the students value the integration of the nursing model with the care process in the learning
based on the simulation of cases.
- To evaluate the sensations as perceived by the students during the simulation process.
- To evaluate the students’ attitude in relation with the incorporation of the scientific evidence to improve clinical
practice.
- To evaluate the degree of difficulty manifested by the student in relation with the documentation process.
- To evaluate the suitability of the argumentation and the student’s decision to the question formulated in the
clinical case.
Methodology: the subject of Medical-chirurgic nursing. Adult 1 from the Nursing Department of the Universitat de
Vic initiated a learning experience based on problem solving, with 2nd year students. The lecturers responsible for
the seminars developed the evaluation of the experience via survey. This survey was answered a month after the
simulation in the laboratory, when the results obtained in this laboratory were contrasted between the students and
the teachers, after visualizing the recording developed during the simulation.
In the context of the seminar on case simulations of cases, a question/problem was introduced. Departing from
this, the students, in group, had to document themselves with the support of a guide. To evaluate the attitude in
front of the question/problem a type Likert questionnaire was designed. The evaluation of the degree of difficulty
was registered through the evaluation scales.
To evaluate the decision taken, the abstracts developed by the 13 practical groups in their essays were evaluated.
Results: the development of the simulation at the laboratory was evaluated with a high degree of the students
(68,8%) with a scoring between 6 and 8, while a 26,6% evaluated it between 9 and 10. Just 4,7% of the students
evaluated it with a 5.
The integration of the Nursing model was evaluated by 86% of the students between 7 and 10. The global
evaluation of the simulation was evaluated by the students with a score of 8 (34,4%), followed by the score of 7
(28,1%). 7,2% scored it 9 to 10. 93,3% assured they knew the literature that would help them to improve their
assistance 86,7% are expecting to achieve solid arguments in relation with their decisions if the consulted
documentation has quality.
77,8% of the students consider to be more satisfied as they know how to incorporate the evidence based on
practice.
Regarding to the degree of difficulty in the documentation process, the biggest is how to search in the literature
reference data bases.
Conclusions: learning through the simulation of cases is a validated strategy that the student values positively,
while it allows to develop skills for professional practice.
The teaching strategy to integrate the evidences in the decision making is considered positive, but, after analysing
the results, some aspects must be modified to improve it, to further assess the documentation process and to
further affect the criticism and the reflection, so the research findings can be applied in practice.RESUMEN

Evaluating the impact of filming on the number of errors committed by nursing students to determine the efficacy of simulated clinical situations
Clinic simulation as a training and knowledge method allows people experiment a real event representation with the aim of acquiring knowledge, abilities and aptitudes. The filming of the staging represents a useful tool to review the decisions taken and the actions they did, with the purpose to highlight the strengths, weaknesses and the areas for improvement. The article describes a study carried out by a group of students in second course of nursing, and it tries to evaluate if there is any influence if somebody is filming you during the clinic simulation, does it make you do more errors or not?Peer Reviewe
Lapsuuden kiintymyssuhteiden vaikutukset myöhemmin elämässä : Kirjallisuuskatsaus
Tämä on kirjallisuuskatsaus, jossa selvitettiin lapsuuden kiintymyssuhteiden merkityksiä myöhemmin elämässä. Kiintymyssuhde lähtee muodostumaan lapsen ja hoivaajan välille heti syntymästä alkaen vuorovaikutuksen pohjalta. Turvallisessa kiintymyssuhteessa lapsen tarpeisiin ja hätään vastataan johdonmukaisesti ja turvallisesti. Turvattomassa kiintymyssuhteessa ja sen eri muodoissa lapselle ei kyetä luomaan turvallisuuden tunnetta ja hoivaajan vastaaminen lapsen tunteisiin on ristiriitaista.
Lapsuuden kiintymyssuhteiden merkitykset myöhemmin elämässä toimi kirjallisuuskatsauksen tutkimuskysymyksenä. Kirjallisuuskatsaukseen valikoitui 16 artikkelia, jotka vastasivat tutkimuskysymykseen ja läpäisivät sisäänottokriteerit. Tutkimuksista luokiteltiin tulokset fyysisiin, psyykkisiin ja sosiaalisiin vaikutuksiin ja turvalliseen ja turvattomaan kiintymyssuhteeseen.
Fyysisiä vaikutuksia oli paljon. Useissa tutkimuksissa kävi ilmi turvattoman kiintymyssuhteen vaikutus altistavana tekijänä lapsuusiän lihavuuteen ja fyysisiin sairauksiin. Uniongelmien ja kiintymyssuhteiden välillä yhteyttä ei havaittu.
Hermostollisesti eroavia vaikutuksia turvallisessa ja turvattomassa kiintymyssuhteessa ilmeni aikuisuudessa asti. Turvattomassa kiintymyssuhteessa ilmeni enemmän fyysisiä oireita migreenissä sekä lisääntyneitä masennusoireita ja itsemurha-ajatuksia. Sosiaalisista vaikutuksista ainoaksi alaluokaksi valikoituivat sosiaaliset taidot. Turvaton kiintymyssuhde oli selvä riski huonompiin sosiaalisiin taitoihin myöhemmin elämässä. Jatkotutkimusehdotuksena on tarkempi tutkimus kiintymyssuhteiden ja mielenterveyden, lihavuuden tai syömishäiriön välisestä yhteydestä.The thesis was a literature review on the effects of childhood attachment relationships on later life. Attachment between a child and a caretaker begins to form right after the birth. In a secure attachment relationship, the needs of a child are met consistently and in a safe manner. In an insecure attachment relationship, and in its various forms, the needs are responded to in a conflicting fashion, thus generating a feeling of insecurity.
With the help of a research question the effects of childhood attachments on later life were examined. A total of sixteen research articles on childhood attachment met the se-lection criteria for the thesis. The themes of the articles were categorized into physical, mental and social effects.
Physical effects were abundant. Many studies revealed that insecure attachment led to childhood and adolescence obesity, physical illnesses and other disorders. However, no connection between insecure attachment and sleeping disorders was recognized.
The security and insecurity of the attachment were found to be associated with differ-ences in the nervous system in adulthood. Moreover, there was a connection between childhood insecurity and physical symptoms in migraines. Depression and suicide-ideas were the most important mental effects linked with an insecure attachment. Social skills were the only social effect that was reviewed. Insecure attachment appeared to be a risk for poorer social skills. Suggestion for further research could be a study on the connection between attachment and mental health, obesity or eating disorders
Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)
Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters.
Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs).
Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001).
Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio
Soil salinity changes over 24 years in a Mediterranean irrigated district
The editor final version is available at:
http://www.sciencedirect.com/science/journal/00167061Soil degradation from salt accumulation, sodication, or both, is a threat or a fact in many irrigated lands. Salinization has often been assessed from changing cropping patterns over time, and often the trends in salinization have not been quantified. Our objective was to identify trends in salinization or desalinization by direct measurements of soil salinity where a consistent methodology was maintained over time. The soils of the Flumen irrigation district (27,500 ha) in Aragón, Spain, were sampled in 1975. The same plots were sampled again in 1985/86 and in 1999. There were 140 sampling points in 1975, and 66 in each of the other two surveys. The mean sampling depth was 103 cm, resulting in 909 soil samples and 8603 analytical determinations. Analytical results for salinity, individual ions, and pH retrieved from the first survey are compared with the two subsequent surveys. The electrical conductivity of the saturated extract (ECe) and the sodium adsorption ratio (SAR) of the extract were determined through the soil profiles, allowing us to compare the results from the three surveys. The upper meter of the soil was less saline in 1999 than in 1975. The median ECe of non-saline soils changed only slightly, while in the saline areas the median ECe for comparable soil depths averaged over 1 m was 5.9 dS m-1 in 1975, 3.1 dS m-1 in 1985/86, and 1.9 dS m-1 in 1999. The median of the maximum SAR to the same depth also decreased from 22.0 (mmol/L)0.5, to 15.1 (mmol/L)0.5, and to 10.5 (mmol/L)0.5 for the same three periods. Thus, soil salinity in the upper meter of soil has decreased during the last 24 years.This article is a result of the research project AGL2000-1775-C03-01 funded by the Spanish Ministry of Science and Technology, and of several previous projects funded by INIA.Peer reviewe

Overland water and salt flows in a set of rice paddies
The final version is available at:
http://www.sciencedirect.com/science/journal/03783774Cultivation of paddy rice in semiarid areas of the world faces problems related to water scarcity. This paper aims at characterizing water use in a set of paddies located in the central Ebro basin of Spain using experimentation and computer simulation. A commercial field with six interconnected paddies, with a total area of 5.31 ha, was instrumented to measure discharge and water quality at the inflow and at the runoff outlet. The soil was classified as a Typic Calcixerept, and was characterised by a mild salinity (2.5 dS m 1) and an infiltration rate of 5.8 mm day-1. The evolution of flow depth at all paddies was recorded. Data from the 2002 rice growing season was elaborated using a mass balance approach to estimate the infiltration rate and the evolution of discharge between paddies. Seasonal crop evapotranspiration, estimated with the surface renewal method, was 731 mm (5.1 mm day-1), very similar to that of other summer cereals grown in the area, like corn. The irrigation input was 1,874 mm, deep percolation was 830 mm and surface runoff was 372 mm. Irrigation efficiency was estimated as 41%. The quality of surface runoff water was slightly degraded due to evapoconcentration and to the contact with the soil. During the period 2001-2003, the electrical conductivity of surface runoff water was 54% higher than that of irrigation water. However the runoff water was suitable for irrigation. A mechanistic mass balance model of inter-paddy water flow permitted to conclude that improvements in irrigation efficiency can not be easily obtained in the experimental conditions. Since deep percolation losses more than double surface runoff losses, a reduction in irrigation discharge would not have much room for efficiency improvement. Simulations also showed that rice irrigation performance was not negatively affected by the fluctuating inflow hydrograph. These hydrographs are typical of turnouts located at the tail end of tertiary irrigation ditches. In fact, these are the sites where rice has been historically cultivated in the study area, since local soils are often saline-sodic and can only grow paddy rice taking advantage of the low salinity of the irrigation water. The low infiltration rate characteristic of these saline-sodic soils (an experimental value of 3.2 mm day-1 was obtained) combined with a reduced irrigation discharge resulted in a simulated irrigation efficiency of 60%. Paddy rice irrigation efficiency can attain reasonable values in the local saline-sodic soils, where the infiltration rate is clearly smaller than the average daily rice evapotranspiration.This research was funded by the Plan Nacional de I+D+i of the Government of Spain, through grant AGL2000-1775.
