Abstract
INTRODUCTION AND OBJECTIVES Asthma is a chronic and heterogeneous disease that affects people of all ages and has a high estimated increase in prevalence worldwide. Asthma control represents a main goal in the disease management. International studies revealed low levels of disease control resulting in a significant burden for healthcare systems, not only in terms of quality of life, but also in terms of health costs. Modifiable and non-modifiable factors have been identified as relating to poor asthma control level. In this study we evaluated the distribution of asthma control levels in Portuguese adult population and examine the determinants associated with uncontrolled asthma. MATERIALS AND METHODS Using a similar methodology to the one employed in the Asthma Insights and Reality in Europe (AIRE) survey, 327 active asthmatic patients were identified by random phone number and completed a questionnaire during 2011 to 2012. Asthma control was assessed by the evaluation of GINA based symptom control, by Asthma Control Test.äó (ACT) and by self-perception of control. To examine the relationship between uncontrolled asthma and its determinants, univariate logistic regression analysis, sequential multivariable regression and population attributable risk percentage were determinate. RESULTS 35.2% active asthmatic patients had uncontrolled asthma, 64.8% partially controlled and none of the individuals had total control of asthma assessed by ACT test. Factors significantly associated with poor asthma control scores were: age (OR 1.02 per year of age; 95% CI: 1.01.Çô1.03), female sex (OR 1.87; 95% CI: 1.15.Çô3.04), educational level (OR 0.5; 95% CI: 0.28.Çô0.89 at high school level or over), occupation (OR 4.92; 95% CI: 2.12.Çô11.42 if looking for a first job or unemployed) (OR 2.51; 95% CI: 1.35.Çô4.65 if being retired), income (OR 0.23; 95% CI: 0.07.Çô0.72 if >619 euros), BMI (OR 1.09 per BMI unit; 95% CI: 1.03.Çô1.14), having rhinitis symptoms (OR 4.40; 95% CI: 2.56.Çô7.58) and using inhaled corticosteroids (OR 0.44; 95%CI: 0.24.Çô0.82 if used in the past or never used). Looking for a first job or being unemployed, BMI and having rhinitis symptoms remained significant after multivariate adjustments. CONCLUSIONS Uncontrolled asthma was associated with several determinants. Their identification can contribute to improve asthma care both from clinical and from public health perspectives.

Abstract
Abstract
Study question
Can non-invasive preimplantation genetic testing of aneuploidies (niPGT-A) improve the clinical outcome in good prognosis patients compared to morphological embryo selection without aneuploidy testing?
Summary answer
Embryonic cell-free DNA (cfDNA) in the blastocyst culture medium offers more objective information for blastocyst selection, resulting in higher ongoing pregnancy rate in good-prognosis patients.
What is known already
One of the biggest challenges in IVF is accurately selecting viable embryos that are most likely to produce a healthy child at home after embryo transfer. Trophectoderm biopsy and PGT-A have improved implantation and clinical pregnancy rates per transfer; however, two recent studies have shown that PGTA does not improve clinical pregnancy rates below 35 years. A non-invasive alternative is to analyze (the cfDNA) in blastocyst culture medium. Several studies have shown that cfDNA testing on blastocyst culture medium at day 6 of development allows detection of aneuploidies with high concordance rates compared to TE biopsy and inner cell mass
Study design, size, duration
This observational study reports data from September 2020 to December 2021. During this period, niPGT-A was performed on 25 patients under 35 years of age whit average age of 32, where cfDNA analysis was applied to the culture medium of 92 blastocysts. A total of 20 single embryo transfers (SETs) have been performed so far, comparing the results with 31 transfers performed in the same period based only on morphological criteria.
Participants/materials, setting, methods
In the niPGT-A group, embryos were cultured in a Geri incubator up to day-4, and then individually cultured in 10 µl drops of CCSS (Fujifilm) until day 6 in an ESCO –system whit low oxygen concentration. At day-6, blastocysts were vitrified, and media collected in sterile PCR tubes after at least 40 hours in culture. After collection, media were immediately frozen and analyzed by Next Generation Sequencing analysis. Deferred transfer was performed according to media results.
Main results and the role of chance
In the niPGT-A group euploidy rate was 57% whit 8% non- informative results. Pregnancy rate was 80% with 75% ongoing pregnancy and 5% miscarriage rates, having 8 live births up to now. For the morphology group, pregnancy rate was 58% with 55% ongoing pregnancy and 3% miscarriage rates.
We did a secondary analysis identifiying which blastocyst we would be transfered, if only morphology would be considered. We observed that in 65% of the cases we would choose the same embryo as with niPGT-A, however in 35% of the cases we would have transferred a blastocyst with an aneuploid medium. Regarding blastocyst quality for throphoectoderm classified as A,B or C the euploidy rate were 62%,58% and 33% respectively, and pregnancy rates were 100%, 78% and 33%. For inne cell mass, similar euploidy rates werw observed for blastocyst classified as A,B or C (59%,52% and 57% respectively) and pregnancy rates were 100%, 73% and 100%. Evaluating the expansion grade in blastocoel no differences were observed in euploidy rates for cathegories 4, 5 and 6 (52%, 54% and 50% respectively) and pregnancy rates were 82%, 100% and 100%. We observed the lower pregnancy rate for blastocysts whit throphoectoderm C previously suggested by other authors.
Limitations, reasons for caution
Our results are encouraging since this group of good prognosis could improve their ongoing pregnancy rate even having a good reproductive prognosis whit morphology selection. Larger randomized controlled trials are needed to verify and extend our findings in this age range
Wider implications of the findings
These results support the clinical application of niPGT-A in the laboratory routine as a proritization tool, without the need of embryo manipulation, reducing subjectivity for blastocyst selection compared to morphology and increasing the ongoing pregnancy rate in good prognosis patients

Abstract
Introduction The COVID-19 pandemic has disrupted many aspects of clinical practice in oncology, particularly regarding early cancer diagnosis, sparking public health concerns that possible delays could increase the proportion of patients diagnosed at advanced stages. In 2009, a cancer fast-track program (CFP) was implemented at the Clinico-Malvarrosa Health Department in Valencia, Spain with the aim of shortening waiting times between suspected cancer symptoms, diagnosis and therapy initiation. Objectives The study aimed to explore the effects of the COVID-19 pandemic on our cancer diagnosis fast-track program. Methods The program workflow (patients included and time periods) was analysed from the beginning of the state of alarm on March 16th, 2020 until March 15th, 2021. Data was compared with data from the same period of time from the year before (2019). Results During the pandemic year, 975 suspected cancer cases were submitted to the CFP. The number of submissions only decreased during times of highest COVID-19 incidence and stricter lockdown, and overall, referrals were slightly higher than in the previous 2 years. Cancer diagnosis was confirmed in 197 (24.1%) cases, among which 33% were urological, 23% breast, 16% gastrointestinal and 9% lung cancer. The median time from referral to specialist appointment was 13 days and diagnosis was reached at a median of 18 days. In confirmed cancer cases, treatment was started at around 30 days from time of diagnosis. In total, 61% of cancer disease was detected at early stage, 20% at locally advanced stage, and 19% at advanced stage, displaying time frames and case proportions similar to pre-pandemic years. Conclusions Our program has been able to maintain normal flow and efficacy despite the challenges of the current pandemic, and has proven a reliable tool to help primary care physicians referring suspected cancer patients.

Abstract
To determine the efficacy and adverse events of the administration of angiotensin-converting enzyme inhibitors for the management of preclinical myxomatous mitral valve disease in dogs. A comprehensive search using Pubmed/MEDLINE, LILACS and CAB abstracts databases was performed. Randomised clinical trials that assessed efficacy and adverse events of angiotensin-converting enzyme inhibitors for the management of preclinical myxomatous mitral valve disease in dogs were included. Certainty of evidence was rated using GRADE methods. Four randomised clinical trials were included. While safe, angiotensin-converting enzyme inhibitors administration to dogs with myxomatous mitral valve disease and cardiomegaly results in little to no difference in the risk of development congestive heart failure (high certainty of evidence; relative risk: 1.03; 95% confidence interval: 0.87 to 1.23) and may result in little to no difference in cardiovascular-related (low certainty of evidence; relative risk: 1.01; 95% confidence interval: 0.54 to 1.89) and all-cause mortality (low certainty of evidence; relative risk: 0.93; 95% confidence interval: 0.63 to 1.36). Administration of angiotensin-converting enzyme inhibitors to dogs with myxomatous mitral valve disease without cardiomegaly may result in a reduced risk of congestive heart failure development. However, the range in which the actual effect for this outcome may be, the "margin of error," indicates it might also increase the risk of congestive heart failure development (low certainty of evidence; relative risk: 0.86; 95% confidence interval: 0.54 to 1.35). Administration of angiotensin-converting enzyme inhibitors to dogs with preclinical myxomatous mitral valve disease and cardiomegaly results in little to no difference in the risk of the development of congestive heart failure and may result in little to no difference in cardiovascular-related and all-cause mortality. The certainty of evidence of the efficacy of angiotensin-converting enzyme inhibitors administration to dogs without cardiomegaly was low.

Abstract
Study question
Can non-invasive preimplantation genetic testing of aneuploidies (niPGT-A) improve the clinical outcome in IVF patients after proper validation?
Summary answer
We demonstrate the usefulness of the embryonic cell-free DNA (cfDNA) in the blastocyst culture medium to select more objectively the blastocysts with higher implantation potential.
What is known already
One of the greatest challenges in IVF is accurately selecting viable embryos that are more likely to achieve healthy livebirths following embryo transfer. Trophectoderm (TE) biopsy and PGT-A provide a direct assessment of chromosome status and improve implantation and clinical pregnancy rates per transfer. A non-invasive alternative is to analyse embryonic cfDNA in the blastocyst culture medium. Previous studies have shown that cfDNA testing in culture medium of blastocysts on day 6 of development allows aneuploidy detection with high concordance rates compared to TE biopsy and inner cell mass (Rubio et al., 2020).
Study design, size, duration
Observational study of the clinical application of niPGT-A (July 2020-December 2020). The clinical application consisted in a first validation phase, comparing TE biopsies with cfDNA in the media of 28 blastocysts. And, in a second phase, niPGT-A was applied and the outcome of 13 single embryo transfers (SETs) compared to 13 PGT-A SETs and 130 IVF/ICSI SETs performed in a period of six months. In the three groups, women and donors age was ≤38 years.
Participants/materials, setting, methods
Embryos were cultured in a Geri incubator (Merck) up to day 4, and then individually cultured in 10µl drops of CCSS (Fujifilm) until day 6 in a bench-top K-system. At day 6, blastocysts were vitrified, and media collected in sterile PCR tubes after at least 40 hours in culture. After collection, media were immediately frozen and analyzed by NGS analysis in our reference laboratory (Igenomix, Spain). Deferred transfer was performed according to media results.
Main results and the role of chance
Before the first clinical cases, a validation of the protocol comparing the results of cfDNA with the TE biopsies of the same day–6 blastocyst was performed, and ploidy concordance rates were 87.5%.
Similar results were found for niPGT-A and PGT-A in terms of aneuploidy results and in clinical outcomes. The percentages of informative results were 95% and 97% and the aneuploidy rates were 44% and 46%, for niPGT-A and PGT-A, respectively. Clinical pregnancy rates were in both groups of aneuploidy testing, 69.2%, with 8 ongoing pregnancies (61.5%) and 4 tested by prenatal screaning NACE. For untested embryos clinical pregnancy (57.7%) and ongoing pregnancy rates (48.5%) were lower than in the two groups of tested embryos (niPGT-A and PGT-A).
In the niPGT-A cycles embryo transfer was performed according to media results and morphology. We did a secondary analysis of which blastocyst we would transfer, if only morphology is considered. We observed that if we only select the embryos by morphology, in 61.5% of the cases we would choose the same embryo than with niPGT-A, and in 30.4% of the cases we would transfer a blastocyst with an aneuploid medium.
Limitations, reasons for caution
Our results are encouraging but should be interpreted with caution due to the small sample size. Larger and randomized controlled trials are needed to verify and extend our findings in each group.
Wider implications of the findings: We observed consistent results for niPGT-A compared to TE biopsies in our internal validation. These results endorse the clinical application of niPGT-A in the routine of the laboratory and can avoid the embryo manipulation also reducing the subjectivity when embryos are selected only by morphology.

Abstract
Background Cancer is the second leading cause of mortality worldwide. Integrating different levels of care by implementing screening programmes, extending diagnostic tools and applying therapeutic advances may increase survival. We implemented a cancer fast-track programme (CFP) to shorten the time between suspected cancer symptoms, diagnosis and therapy initiation. Patients and methods Descriptive data were collected from the 10 years since the CFP was implemented (2009-2019) at the Clinico-Malvarrosa Health Department in Valencia, Spain. General practitioners (GPs), an oncology coordinator and 11 specialists designed guidelines for GP patient referral to the CFP, including criteria for breast, digestive, gynaecological, lung, urological, dermatological, head and neck, and soft tissue cancers. Patients with enlarged lymph nodes and constitutional symptoms were also considered. On identifying patients with suspected cancer, GPs sent a case proposal to the oncology coordinator. If criteria were met, an appointment was quickly made with the patient. We analysed the timeline of each stage of the process. Results A total of 4493 suspected cancer cases were submitted to the CFP, of whom 4019 were seen by the corresponding specialist. Cancer was confirmed in 1098 (27.3%) patients: breast cancer in 33%, urological cancers in 22%, gastrointestinal cancer in 19% and lung cancer in 15%. The median time from submission to cancer testing was 11 days, and diagnosis was reached in a median of 19 days. Treatment was started at a median of 34 days from diagnosis. Conclusions The findings of this study show that the interval from GP patient referral to specialist testing, cancer diagnosis and start of therapy can be reduced. Implementation of the CFP enabled most patients to begin curative intended treatment, and required only minimal resources in our setting. Our CFP easily connects GPs and hospital specialists. Our CFP shortens assessment time in patients with suspected cancer, adding to quality care. Our CFP decreases emotional stress in patients without cancer.

Abstract
IntroductionGlucagon-like peptide-1 (GLP-1) is an endogenous peptide that stimulates insulin secretion and decreases glucagon secretion. The use of GLP-1 receptor agonists (GLP-1RA) showed efficacy reducing the weight and glucose levels in patients with and without type 2 diabetes. This effect was also associated with a decreased risk of major cardiovascular events.ObjectivesOur aim is to review the role of GLP-1RA in psychiatric patients at cardio-metabolic risk due to antipsychotics treatment.Methods
We reviewed articles published in PubMed using the keywords: “GLP-1” “glucagon like peptide” “antipsychotics” and “psychiatry”.ResultsThe number need to treat (NNT) to achieve clinical meaningful weight loss was 3.8. GLP-1RA treatment was also associated with greater reductions in body mass index, fasting glucose, HbA1c and visceral fat. This effect is true for antipsychotic treatment in general and for those on clozapine and olanzapine in particular. Overall, the GLP-1RA are well tolerated with nausea being the most common related adverse effect. Other variables such as age, sex, psychosis severity, nausea or any adverse drug reaction did not affect the weight loss.ConclusionsStudies showed a promising role in the management of antipsychotics induced weight gain, particularly in clozapine and olanzapine treated patients. Although these promising results, the route of administration, with a daily or weekly subcutaneous injection, and the GLP-1RA associated financial costs, can be viewed as important factors which can limit the wide use of this type of treatment in psychiatric patients.DisclosureNo significant relationships.

Abstract
The Bilbao estuary (SE Bay of Biscay) is a recovering ecosystem whose sediments are still contaminated. They represent a potential risk for the biota including benthic and demersal species living in direct contact with the sediment. In this context, the present study aims to survey trends of the health status of the Bilbao estuary based on sediment chemistry and sole (Solea spp.) histopathology. Monitoring campaigns were carried out every autumn from 2011 to 2017 along the estuary. Contaminant levels were measured in sediments; liver, gills and gonads of juvenile fish were collected for histopathology. Overall, contaminant levels fluctuated throughout the years, with highest values recorded in the earlier years of the study period. Sole histopathology showed alterations of mild severity. Results permitted to assess the environmental health status of the Bilbao estuary during 7 years, although no clear temporal trend was detected. Longer-term monitoring programmes are necessary to confirm the ecosystem recovery.

Abstract
UNLABELLED Local anaesthetic injection between the tibial and commmon peroneal nerves within connective tissue sheath results in a predictable diffusion and allows for a reduction in the volume needed to achieve a consistent sciatic popliteal block. Using 3D ultrasound volumetric acquisition, we quantified the visible volume in contact with the nerve along a 5cm segment. METHODS We included 20 consecutive patients scheduled for bunion surgery. Ultrasound guided popliteal block was performed using a posterior, out of plane approach at the level of división of the sciatic nerve. Thirty ml of mepivacaine 1.5% and levobupivacaine 0.5% were slowly injected while assessing the injection pressure and the diffusion of the local anaesthetic. Volumetric acquisition was performed before and after the block to quantify the the volume of the sciatic nerve and the volume of the surrounding hypoechoic halo contained inside the connective tissue in a 5cm segment. RESULTS All blocks were successful within 20min after the injection. The total estimated volume contained inside the common connective tissue sheath was 6.8±2.6cm3. Of this, the volume of the halo sorrounding the nerve was 4.4±1.7cm3 and the volume inside the sciatic nerve was 2.4±1.7cm3. CONCLUSIONS The volume of local anaesthetic in close contact with the sciatic nerve can be estimated by volumetric acquisition. Our results suggest that the effective volume of local anaesthetic needed for a successful sciatic popliteal block could be reduced to less than 7ml.

Abstract
Taking into account the influence of Si in osteoblast cell proliferation, a series of sol-gel derived silicon based coating was prepared by controlling the process parameters and varying the different Si-alkoxide precursors molar rate in order to obtain materials able to release Si compounds. For this purpose, methyltrimethoxysilane (MTMOS) and tetraethyl orthosilicate (TEOS) were hydrolysed together and the sol obtained was used to dip-coat the different substrates. The silicon release ability of the coatings was tested finding that it was dependent on the TEOS precursor content, reaching a Si amount value around ninefolds higher for coatings with TEOS than for the pure MTMOS material. To test the effect of this released Si, the in vitro performance of developed coatings was tested with human adipose mesenchymal stem cells finding a significantly higher proliferation and mineralization on the coating with the higher TEOS content. For in vivo evaluation of the biocompatibility, coated implants were placed in the tibia of the rabbit and a histological analysis was performed. The evaluation of parameters such as the bone marrow state, the presence of giant cells and the fibrous capsule proved the biocompatibility of the developed coatings. Furthermore, coated implants seemed to produce a qualitatively higher osteoblastic activity and a higher number of bone spicules than the control (uncoated commercial SLA titanium dental implant).

Abstract
BACKGROUND Since impairments of the trunk muscles are observed in stroke subjects, who also demonstrate limitations in performing the sit-to-stand (STS) task, it is possible that these limitations are related to decreased strength of the trunk muscles. AIM To compare the STS performances and isokinetic measures of trunk strength between stroke and matched healthy subjects and to investigate if there were associations between STS performances and strength of the trunk muscles. DESIGN Exploratory study. SETTING University Laboratory. POPULATION Eighteen stroke and 18 match-ed healthy subjects. METHODS Subjects performed the five-repetition sit-to-stand test and were also asked to stand up and sit down at both self-selected and fast speeds (motion analysis system). The scores of the five-repetition sit-to-stand test and the total duration of the STS, as well as the duration of phases I and II were used as measures of STS performances. Isokinetic strength of the trunk muscles was assessed at a speed of 60º/s: concentric peak torque and total normalized work. RESULTS Stroke subjects showed poorer STS performances (P≤0.02), except for the duration of phase I at self-selected speed, as well as decreased strength of the trunk muscles (P≤0.001). Significant and negative correlations were found between STS performance and trunk strength variables, which were classified as low (-0.38≤r≤-0.49) or moderate (-0.50≤r≤-0.63). CONCLUSION In general, poorer STS performances observed in stroke subjects was related to weakness of the trunk muscles. CLINICAL REHABILITATION IMPACT Evaluation and interventions involving trunk strength should be included in rehabilitation of stroke subjects, who show limitations in STS performances.

Abstract
Liver and gonad histopathology, biometric parameters and hepatic metal bioaccumulation were assessed monthly over a one-year period in common soles from the Basque continental shelf, in order to determine baseline levels and confounding factors within biomonitoring studies. Biometric parameters and hepatic metal bioaccumulation varied according to season and gender. Accordingly, hepatic histopathological traits presented seasonal variations related to the reproductive cycle. However, the hepatic histopathological index showed that seasonality and gender were not significant confounding factors. Conversely, the gonad histopathological index was modulated by season and gender. As for organ comparison, the liver endured more severe histopathological damage than the gonad. In brief, the sampling period and gender may not affect the estimation of hepatic histopathological indices for biomonitoring purposes. Nonetheless, due to different sensitivities to environmental 'noise' variables, the sampling period and gender differentiation should be thoroughly considered for the assessment of gonad histopathology, biometrics and metal bioaccumulation.

Abstract
In the present study, the fertilizing potential of semen recovered from slaughtered bulls epididymis was evaluated after cryopreservation, by conventional techniques and flow cytometry methods. The cauda epididymal was dissected and sperm were recovered and evaluated for volume, sperm concentration, and membrane and acrosome integrity using a flow cytometer. Sperm fertility potential was tested by in vitro fertilization (IVF). For each bull, three trials of IVF were performed. Before freezing, on average, the sperm concentration was 216 ± 27.5 × 10(6) sperm/ml. Sperm viability averaged 86.5 ± 4%. The mean percentage of sperm with intact plasma membrane and acrosome before and after cryopreservation was 90.7 ± 2.9% and 90.8 ± 1.9% (P≥0.05), respectively. The fertilization rate using frozen/thawed epididymal semen averaged 64.1 ± 3.9% fertilization with no significant differences between bulls (P>0.05). For the bull considered as control, the fertilization rate was 72.2 ± 4.5%, differing significantly (P>0.05) from the frozen/thawed epididymal semen's fertilization rate. In conclusion, it is possible to use in vitro techniques with cryopreserved spermatozoa obtained from bull's epididymis using a controlled rate freezing method with a predetermined freezing curve, and with assessment of sperm's viability by conventional techniques and flow cytometry methods, together with the fertilizing ability of cryopreserved epididymal spermatozoa.

Abstract
Amphicarpy is a fascinating reproductive strategy, defined as fruit produced both below the soil surface and as aerial fruit on the same plant. Trifolium polymorphum is a grassland species subject to herbivory that combines amphicarpy with vegetative reproduction through stolons. Underground flowers have been described as obligate autogamous and aerial ones as self-compatible allogamous, with aerial floral traits favouring cross-pollination. In the present work we performed different pollination treatments on aerial flowers to analyse rates of pollen tube development and offspring fitness, measured as fruit set, seed production and germination percentage. This last variable was compared to that of seeds produced underground. No significant differences were found between fruit set in self- and cross-pollinations. Seed production was higher in self-pollinations, which is consistent with the higher rate of pollen tube development observed in self-crosses. Spontaneous self-pollination is limited in aerial flowers; thus pollen transfer by means of a vector is required even within the same flower. Germination tests showed that aerial seeds produced after self- and cross-pollination did not differ in fitness, but underground seeds had higher germination percentage than aerial ones. Thus, we conclude that T. polymorphum has a mixed mating system. In grasslands with heavy grazing pressure, clonal propagation and underground seed production ensure persistence in the field. An intermediate level of selfing in aerial flowers ensures offspring, but morphological (herkogamy) and functional (dicogamy) floral traits maintain a window to incorporate genetic variability, allowing the species to tolerate temporal and spatial pressures.

Abstract
Maize was first domesticated in a restricted valley in south-central Mexico. It was diffused throughout the Americas over thousands of years, and following the discovery of the New World by Columbus, was introduced into Europe. Trade and colonization introduced it further into all parts of the world to which it could adapt. Repeated introductions, local selection and adaptation, a highly diverse gene pool and outcrossing nature, and global trade in maize led to difficulty understanding exactly where the diversity of many of the local maize landraces originated. This is particularly true in Africa and Asia, where historical accounts are scarce or contradictory. Knowledge of post-domestication movements of maize around the world would assist in germplasm conservation and plant breeding efforts. To this end, we used SSR markers to genotype multiple individuals from hundreds of representative landraces from around the world. Applying a multidisciplinary approach combining genetic, linguistic, and historical data, we reconstructed possible patterns of maize diffusion throughout the world from American "contribution" centers, which we propose reflect the origins of maize worldwide. These results shed new light on introductions of maize into Africa and Asia. By providing a first globally comprehensive genetic characterization of landraces using markers appropriate to this evolutionary time frame, we explore the post-domestication evolutionary history of maize and highlight original diversity sources that may be tapped for plant improvement in different regions of the world.

Abstract
The purpose of this study was to assess the current status of image quality and dose in computed radiographic digital mammography (CRDM) systems. Studies included CRDM systems of various models and manufacturers which dose and image quality comparisons were performed. Due to the recent rise in the use of digital radiographic systems in Mexico, CRDM systems are rapidly replacing conventional film-screen systems without any regard to quality control or image quality standards. Study was conducted in 65 mammography facilities which use CRDM systems in the Mexico City and surrounding States. The systems were tested as used clinically. This means that the dose and beam qualities were selected using the automatic beam selection and photo-timed features. All systems surveyed generate laser film hardcopies for the radiologist to read on a scope or mammographic high luminance light box. It was found that 51 of CRDM systems presented a variety of image artefacts and non-uniformities arising from inadequate acquisition and processing, as well as from the laser printer itself. Undisciplined alteration of image processing settings by the technologist was found to be a serious prevalent problem in 42 facilities. Only four of them showed an image QC program which is periodically monitored by a medical physicist. The Average Glandular Dose (AGD) in the surveyed systems was estimated to have a mean value of 2.4 mGy. To improve image quality in mammography and make more efficient screening mammographic in early detection of breast cancer is required new legislation.

Abstract
This study refers to the performance of Phase I Toxicity Identification Evaluation (TIE) procedures to identify the contaminants (i.e. organic compounds, metals and ammonia) exerting toxicity in marine sediments from the Pasaia harbor (Oiartzun estuary, northern Spain). The effectiveness of the manipulations to reduce toxicity was proved with the marine amphipod survival test (whole-sediment) and the sea urchin embryo-larval assay (elutriates). By means of TIEs it was concluded that organic compounds were the major contaminants exerting toxicity, although toxic effects by metals was also demonstrated. Additionally, the combination of Phase I treatments allowed to investigate the toxicity changes associated to the mobility of contaminants during dredging activities. Therefore, the performance of TIE procedures as another line of evidence in the decision-making process is recommended. They show a great potential to be implemented at different steps of the characterization and management of dredged harbor sediments.

Abstract
This study refers to the integrative assessment of sediment quality in three harbour areas at the Spanish Atlantic Coast: Vigo (Northwestern Spain), Bilbao and Pasajes (Northern Spain). At each site, two lines of evidence have been considered: chemical analyses (metal, PAH and PCB concentrations in sediments and ammonia concentration in bioassays) and toxicity tests (Microtox®, Corophium sp. marine amphipod and Paracentrotus lividus sea urchin larvae). Chemical and ecotoxicological results have been integrated by means of a tabular matrix and a multivariate factorial analysis (FA). Highly toxic samples have been characterised in Vigo and Pasajes harbours while Bilbao samples present toxicity levels ranging from non-toxic to moderately toxic. High toxicity is associated with high levels of contaminants whereas confounding factors (ammonia, organic matter and mud) have been identified to be the main cause of low to moderate toxicity. Based on the obtained results, it can be concluded that deriving potential toxicity of sediments based on comparison with Sediment Quality Guidelines (SQGs) is in agreement to toxicity results in areas presenting high levels of contaminants. However, at lower levels of toxicity (low to moderate), the mismatch between the potential toxicity (SQG approach) and the toxicity measured by bioassays is greater, as the former only accounts for chemical concentrations, without considering the interaction between contaminants and the effect of confounding factors. Contrarily, the multivariate analysis seems to be a robust tool for the integration and interpretation of different lines of evidence in areas affected by different sources of contamination.

Abstract
Four cycles of S(1) family recurrent selection to improve grain yield and resistance to Striga hermonthica have been completed in TZE-Y Pop STR C(0.) In order to determine whether or not to continue with the recurrent scheme, it was desirable to evaluate the amount of residual genetic variance and associated parameters in the population. The objective of this study was to characterize the relative changes in the levels of the genetic variances, heritability estimates and genetic correlation coefficients, and to predict future gains from selection for grain yield, Striga resistance and other agronomic traits. Fifty S(1) families, derived from each cycle, were evaluated under Striga-infested and Striga-free conditions at Mokwa, Ikenne and Abuja, Nigeria, in 2005 and 2007. Under Striga infestation, genetic variances for grain yield, days to anthesis, plant height and Striga damage generally increased in the advanced cycles of selection. In contrast, the genetic variances for days to silk, anthesis-silking interval, ears per plant, ear aspect and number of emerged Striga plants decreased with selection. The advanced cycles of selection significantly out-yielded the original cycle in both research environments. Heritabilities for grain yield, Striga damage and number of emerged Striga plants were significantly greater than zero. The realized gains from selection for grain yield under Striga infestation (52 kg ha(-1) cycle(-1)) and Striga-free conditions (130 kg ha(-1) cycle(-1)) were remarkably lower than the predicted gains (350 and 250 kg ha(-1 )cycle(-1), respectively). Adequate genetic variability exists in cycle 4 of the scheme to ensure future gains from selection.

Abstract
The purpose of this study was to evaluate the dose received by chest x-rays in neonatal care with thermoluminescent dosimetry and to determine the level of exposure where the quantum noise level does not affect the diagnostic image quality in order to reduce the dose to neonates. In pediatric radiology, especially the prematurely born children are highly sensitive to the radiation because of the highly mitotic state of their cells; in general, the sensitivity of a tissue to radiation is directly proportional to its rate of proliferation. The sample consisted of 208 neonatal chest x-rays of 12 neonates admitted and treated in a Neonatal Intensive Care Unit (NICU). All the neonates were preterm in the range of 28-34 weeks, with a mean of 30.8 weeks. Entrance Surface Doses (ESD) values for chest x-rays are higher than the DRL of 50 μGy proposed by the National Radiological Protection Board (NRPB). In order to reduce the dose to neonates, the optimum image quality was achieved by determining the level of ESD where level noise does not affect the diagnostic image quality. The optimum ESD was estimated for additional 20 chest x-rays increasing kVp and reducing mAs until quantum noise affects image quality.

Abstract
The implementation of water quality European Directives requires an intensification of water quality monitoring, within the limits of the Exclusive Economic Zone. Remote sensing technologies can provide a valuable tool for frequent, synoptic, water-quality observations, over large areas. The aim of this study is to assess the ecological status of Basque coastal water bodies using satellite imagery from MODIS sensor, together with optical and chlorophyll-ain situ measurements. Thus, sea surface satellite-derived chl-a algorithms, the OC3 M, OC5 and a Local empirical algorithm, were compared against in situ measurements using satellite in situ match-ups, 90th Percentile (P90) monthly values for the 2005-2010 period. The OC5 algorithm corresponded most accurately with in situ measurements performed in the area, hence, it was selected. A P90 chlorophyll-a map was created with this algorithm to apply the classification scheme required by the directives. The classification of water bodies, based upon satellite-derived chlorophyll-a, could improve considerably the assessment of water quality.

Abstract
Biodiversity recovery measures have often been ignored when dealing with the restoration of degraded aquatic systems. Furthermore, biological valuation methods have been applied only spatially in previous studies, and not jointly on a temporal and spatial scale. The intense monitoring efforts carried out in a highly polluted estuary, in northern Spain (Nervión estuary), allowed for the economic valuation of the costs and the biological valuation of the benefits associated with a 21 years sewage scheme application. The analysis show that the total amount of money invested into the sewage scheme has contributed to the estuary's improvement of both environmental and biological features, as well as to an increase in the uses and services provided by the estuary. However, the inner and outer parts of the estuary showed different responses. An understanding of the costs and trajectories of the environmental recovery of degraded aquatic systems is increasingly necessary to allow policy makers and regulators to formulate robust, cost-efficient and feasible management decisions.

Abstract
In this contribution, the potential use of diffusive gradients in thin-films (DGTs) for the chemical evaluation of transitional water bodies within the Water Framework Directive (WFD) has been studied. The water metal concentration has been evaluated in 13 estuaries in the southeastern Bay of Biscay. The DGTs were deployed in triplicate at two stations in each estuary, delimiting the tidal influence. The DGT results were in the ranges of 2-1570 ng L(-1) for cadmium, 66-515 ng L(-1) for copper, 30-3650 ng L(-1) for nickel and 0.8-95.5 μg L(-1) for zinc. The DGTs provided reliable average labile metal concentrations in highly dynamic systems that were comparable with DGT measurements in coastal and estuarine waters worldwide. In addition, it was possible to discriminate those estuaries more susceptible to environmental impacts, being consistent with the historical contamination of each estuary. Based on the obtained results, a sampling strategy for the monitoring of transitional water bodies using DGTs is proposed.

Abstract
Patients with adenosine deaminase (ADA) deficiency exhibit spontaneous and partial clinical remission associated with somatic reversion of inherited mutations. We report a child with severe combined immunodeficiency (T-B- SCID) due to ADA deficiency diagnosed at the age of 1 month, whose lymphocyte counts including CD4+ and CD8+ T and NK cells began to improve after several months with normalization of ADA activity in Peripheral blood lymphocytes (PBL), as a result of somatic mosaicism caused by monoallelic reversion of the causative mutation in the ADA gene. He was not eligible for haematopoietic stem cell transplantation (HSCT) or gene therapy (GT); therefore he was placed on enzyme replacement therapy (ERT) with bovine PEG-ADA. The follow-up of metabolic and immunologic responses to ERT included gradual improvement in ADA activity in erythrocytes and transient expansion of most lymphocyte subsets, followed by gradual stabilization of CD4+ and CD8+ T (with naïve phenotype) and NK cells, and sustained expansion of TCRγδ+ T cells. This was accompanied by the disappearance of the revertant T cells as shown by DNA sequencing from PBL. Although the patient's clinical condition improved marginally, he later developed a germinal cell tumour and eventually died at the age of 67 months from sepsis. This case adds to our current knowledge of spontaneous reversion of mutations in ADA deficiency and shows that the effects of the ERT may vary among these patients, suggesting that it could depend on the cell and type in which the somatic mosaicism is established upon reversion.

Abstract
SETTING Tuberculosis (TB) affected households in impoverished shantytowns, Lima, Peru. OBJECTIVE To evaluate socio-economic interventions for strengthening TB control by improving uptake of TB care and prevention services. DESIGN Barriers to TB control were characterised by interviews with TB-affected families. To reduce these barriers, a multidisciplinary team offered integrated community and household socio-economic interventions aiming to: 1) enhance uptake of TB care by education, community mobilisation and psychosocial support; and 2) reduce poverty through food and cash transfers, microcredit, microenterprise and vocational training. An interim analysis was performed after the socio-economic interventions had been provided for 2078 people in 311 households of newly diagnosed TB patients for up to 34 months. RESULTS Poverty (46% earned <US$1 per day), depression (40%), stigmatisation (77%), and perceived isolation (39%) were common among TB patients (all P < 0.05 vs. non-patients). The project had 100% recruitment, and involved 97% of TB-affected households in regular visits, 71% in community groups, 78% in psychosocial support and 77% in poverty-reduction interventions. The socio-economic interventions were associated with increases in household contact TB screening (from 82% to 96%); successful TB treatment completion (from 91% to 97%); patient human immunodeficiency virus testing (from 31% to 97%); and completion of preventive therapy (from 27% to 87%; all P < 0.0001). CONCLUSIONS Socio-economic interventions can strengthen TB control activities. KEYWORDS tuberculosis; control; microcredit; poverty;social determinants.
