Freemartinism in replacement ewe-lambs of the Ripollesa sheep breed

Pilar Marí,Joaquim Casellas 대한수의학회 2018 Journal of Veterinary Science Vol.19 No.6

The freemartinism syndrome affects almost all female calves born as co-twins to male calves, whereas little is known about this phenomenon in female sheep. Within this context, 1,185 ewe-lambs from the Ripollesa sheep breed were genotyped for the presence of oY1 polymorphism (a non-autosomal region of the Y chromosome). Neither ewe-lambs from single births (856) nor ewe-lambs from all-female multiple births (170) were revealed as freemartins, whereas five of 159 ewe-lambs from multiple births with male co-twins were freemartins (3.15 ± 1.38%). All freemartin ewe-lambs were confirmed by physical examination of external genitalia. The results confirm a low incidence of freemartinism from heterosexual twin pregnancies in Ripollesa sheep.

Background/Aims: Tight control of inflammation and adjustment of treatment if activity persists is the current strategy for the management of Crohn’s disease (CD). The usefulness of fecal calprotectin (FC) in isolated involvement of the small intestine in CD is controversial. To assess the usefulness of FC to determine the inflammatory activity detected by intestinal ultrasonography (IUS) in ileal CD. Methods: Patients with exclusively ileal involvement CD who underwent IUS and an FC were prospectively included. Simple ultrasound index was used to determine inflammatory activity. The usual statistical tests for comparison of diagnostic techniques were used. Results: One hundred and five patients were included, IUS showed inflammatory activity in 59% of patients and complications in 18.1%. FC showed a significant correlation with IUS in the weak range (Spearman coefficient <i>r</i>=0.502; <i>P</i><0.001); the area under the receiver operating characteristic curve was 0.79 (95% confidence interval, 0.70–0.88; <i>P</i><0.001). The FC value that best reflected the activity in IUS was 100 μg/g with sensitivity, specificity, and positive and negative predictive values of 73.0%, 71.4%, 79.3% and 63.8%, respectively. There were no differences in FC concentration between patients with or without transmural complications. The addition of serum C-reactive protein to FC did not improve the ability to assess IUS activity.Conclusions: FC has a significant correlation with IUS to monitor ileal CD activity. This correlation is weak and it does not allow assessing the presence of CD complications. Both tests should be used in conjunction for tight control of ileal CD. More studies on noninvasive tests in this location are needed.

Marqués-Sánchez Pilar,Cummings Greta,Martínez-Fernández María Cristina,Martínez-Gimeno María Lara,López María,Serrano-Fuentes Néstor 한국간호과학회 2020 Asian Nursing Research Vol.14 No.2

Purpose: To analyze the leadership network structure among nursing leaders in Spain identified through the Grupo40Enfermeras y Universidad event. Methods: A descriptive cross-sectional study using social network analysis was used. Study sample consisted of 210 individuals, of whom 119 received nominations as referents. Structural analysis of the network was conducted using centrality and cohesion. Results: A network structure was generated in which different leadership strategies were identified through InDegree, Eigenvector, and Betweenness Centrality. Five leaders were identified as bridges to other individuals using Betweenness. The whole network presented little cohesion although two highly cohesive cores were detected by K-core measurements. Conclusion: A strategy is needed to support nursing leaders with high degree of Betweenness to serve as bridges to connect other nursing leaders

María-José Castro-Castro,Beatriz Candás-Estébanez,Margarita Esteban-Salán,Pilar Calmarza,Teresa Arrobas-Velilla,Carlos Romero-Román,Miguel Pocoví-Mieras,José-Ángel Aguilar-Doreste,Sociedad Española de 대한진단검사의학회 2018 Annals of Laboratory Medicine Vol.38 No.6

Background: Lipemia, a significant source of analytical errors in clinical laboratory settings, should be removed prior to measuring biochemical parameters. We investigated whether lipemia in serum/plasma samples can be removed using a method that is easier and more practicable than ultracentrifugation, the current reference method. Methods: Seven hospital laboratories in Spain participated in this study. We first compared the effectiveness of ultracentrifugation (108,200×g) and high-speed centrifugation (10,000×g for 15 minutes) in removing lipemia. Second, we compared high-speed centrifugation with two liquid-liquid extraction methods—LipoClear (StatSpin, Norwood, USA), and 1,1,2-trichlorotrifluoroethane (Merck, Darmstadt, Germany). We assessed 14 biochemical parameters: serum/plasma concentrations of sodium ion, potassium ion, chloride ion, glucose, total protein, albumin, creatinine, urea, alkaline phosphatase, gamma-glutamyl transferase, alanine aminotransferase, aspartate-aminotransferase, calcium, and bilirubin. We analyzed whether the differences between lipemia removal methods exceeded the limit for clinically significant interference (LCSI). Results: When ultracentrifugation and high-speed centrifugation were compared, no parameter had a difference that exceeded the LCSI. When high-speed centrifugation was compared with the two liquid-liquid extraction methods, we found differences exceeding the LCSI in protein, calcium, and aspartate aminotransferase in the comparison with 1,1,2-trichlorotrifluoroethane, and in protein, albumin, and calcium in the comparison with LipoClear. Differences in other parameters did not exceed the LCSI. Conclusions: High-speed centrifugation (10,000×g for 15 minutes) can be used instead of ultracentrifugation to remove lipemia in serum/plasma samples. LipoClear and 1,1,2-trichlorotrifluoroethane are unsuitable as they interfere with the measurement of certain parameters.

Slide Session : OS-HEM-03 ; Hematology : Hemophagocytic Syndrome in Internal Medicine: Iden-tification of Infectious Triggers, Therapeutic Manage-ment and Mortality in 88 Patients (REGHEM-GEAS-SEMI)

( Pilar BRITO ZERÓN ),( Marta PEREZ DE LIS NOVO ),( Roberto PÉREZ ALVAREZ ),( Pedro MORAL MORAL ),( Aleida MARTÍNEZ ZAPICO ),( Guadalupe FRAILE ),( Eva FONSECA ),( María VAQUERO HERRERO ),( Angela RUI 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background: To analyze the therapeutic management and the main epidemiological and clinical characteristics related to survival in a large series of patients with hemophagocytic syndrome (HS) diagnosed in Departments of Internal Medicine. Methods: In June 2013, the Study Group of Autoimmune Diseases (GEAS-SEMI) creates a national registry of patients with HS. Patients were diagnosed according to the fulfillment of the criteria of the Histiocytosis Society in 1991 and updated in 2004. Results: At June 15, 2014, the REGHEM registry included 88 patients with HS, 35 (40%) men and 55 (60%) women, with a mean age at diagnosis of 49.16 years (range 12- 84 years). During the admission that led to the diagnosis of SH, acute infections were identified in 50 (57%) patients, including viruses (n=20), bacteria (n=13), mycobacteria (n=8) and parasites/fungi (n=13). Patients were treated with corticosteroids (n=40), etoposide (n=12), cyclosporin A (n=12), methotrexate (n=4), tacrolimus (n=2) rituximab (n=3), intravenous immunoglobulins (n=2) and chemotherapy (n=5). A total of 44 (50%) patients died. The main factors associated with mortality were analytical parameters at diagnosis such as the presence of severe anemia (Hb <9 g/L, 89% vs 66%, p=0.01), platelet count <100,000/mm3 (96% vs 64%, p<0.001), neutropenia <1000/mm3 (59% vs 39%, p=0.044), and bacterial infections as precipitating agent (77% vs 45%, p=0.034); a clinical presentation including lymphadenopathy was associated with a lower mortality (59% vs 39%, p=0.044). Conclusions: Hemophagocytic syndrome is a severe multisystemic disease associated in nearly 50% of cases with an acute infection, and usually requires vital support in intensive care units. Despite this and the use of a complex therapeutic approach, half of the patients died. The main prognostic factor identified is the presence at diagnosis of severe cytopenias and the coexistence of bacterial infections.

Objective: Our aim was to reach a consensus on the management of the most controversial issues of advanced ovarian cancer. Methods: Nominal group and Delphi techniques were used. A steering committee of 5 experts analyzed current management of advanced ovarian cancer, identified controversies, critically analyzed the evidence, and formulated guiding statements for clinicians. Subsequently, a panel of 15 experts was selected to test agreement with the statements through two Delphi rounds. Items were scored on a 4-point Likert scale from 1 (totally disagree) to 4 (totally agree). In the first and second rounds, consensus was considered if ≥70% of answers pertained to category 1 or category 4. Results: Overall, 112 statements were incorporated in the following areas: 1) biomarkers and hereditary ovarian cancer; 2) first-line treatment; 3) recurrent disease when platinum might be the best option; and 4) post-poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors setting. In the first Delphi round, 37 statements reached consensus and did thus not pass to the second round. After the second round, another 18 statements reached consensus. Forty-six of the consensus were with the agreement and 9 with the disagreement. Conclusion: Through the methodology used, a consensus was reached in approximately half of the statements. The results of this work may be useful in addressing the most controversial issues on the management of advanced ovarian cancer.

A chronic subclinical inflammatory status that coexists with immune dysfunction is commonly found in the elderly population. Consumption of foods rich in antioxidants (e.g., cherries) is an attractive strategy to reduce risk from chronic diseases. Based on previous studies showing the antioxidant effect of a Jerte Valley cherry derivative product in humans, the objective of this work was to evaluate the effect of the intake of a Jerte Valley cherry-based beverage on inflammatory load in both young and old ringdoves (Streptopelia risoria). To this purpose, circulating levels of proinflammatory and anti-inflammatory cytokines as well as serum levels of different acute-phase proteins were measured before and after a 10-day treatment with the Jerte Valley cherry-based beverage. Thus, the 10-day treatment with the cherry-based beverage modulated the balance of pro- and anti-inflammatory cytokines in both young and old ringdoves by down-regulating the levels of pro-inflammatory cytokines (interleukin [IL]-1b, tumor necrosis factor-a, and interferon-c) and up-regulating the levels of anti-inflammatory cytokines (IL-4, IL-2, and IL-10). Moreover, the 10-day treatment with the Jerte Valley cherrybased product reduced the levels of several proteins involved in acute-phase responses, such as C-reactive protein, haptoglobin,a2-macroglobulin, and serum amyloid P component. On the other hand, old birds showed imbalanced levels of inflammatory markers toward a pro-inflammatory status, thereby underlining the fact that aging is usually accompanied by systemic inflammation and inflammation-related chronic diseases. To sum up, the data suggest a potential health benefit by consuming the cherry-based beverage, especially in aged populations, through their anti-inflammatory properties.

Factors Affecting the Vineyard Populational Diversity of Plasmopara viticola

Susana Boso,Pilar Gago,José-Luis Santiago,María de la Fuente,María-Carmen Martínez 한국식물병리학회 2019 Plant Pathology Journal Vol.35 No.2

Vitis vinifera is very susceptible to downy mildew (Plasmopara viticola). A number of authors have suggested different genetic populations of this fungus exist in Europe, each showing a different degree of virulence. Work performed to date indicates this diversity to be the result of different factors. In areas where gene flow is greater and recombination more frequent, the diversity of P. viticola appears to be wider. In vineyards isolated by geographic barriers, a race may become dominant and produce clonal epidemics driven by asexual reproduction. The aim of the present work was to identify the conditions that influence the genetic diversity of P. viticola populations in the vineyards of northwestern Spain, where the climatic conditions for the growth of this fungus are very good. Vineyards situated in a closed, narrow valley of the interior, in more open valleys, and on the coast were sampled and the populations of P. viticola detected were differentiated at the molecular level through the examination of microsatellite markers. The populations of P. viticola represented in primary and secondary infections were investigated in the same way. The concentration of airborne sporangia in the vegetative cycle was also examined, as was the virulence of the different P. viticola populations detected. The epidemiological characteristics of the fungus differed depending on the degree of isolation of the vineyard, the airborne spore concentration, and on whether the attack was primary or secondary. Strong isolation was associated with the appearance of dominant fungal races and, therefore, reduced populational diversity.

Leaf samples of Solanum lycopersicum, Capsicum annuum,Cucurbita moschata, Cucurbita pepo, Sechium edule and Erythrina spp. were collected. All samples were positive for begomoviruses using polymerase chain reaction and degenerate primers. A sequence of ~1,100 bp was obtained from the genomic component DNA-A of 14 samples. In addition, one sequence of ~580 bp corresponding to the coat protein (AV1) was obtained from a chayote (S. edule) leaf sample. The presence of Squash yellow mild mottle virus (SYMMoV) and Pepper golden mosaic virus (PepGMV) were confirmed. The host range reported for SYMMoV includes species of the Cucurbitaceae,Caricaceae and Fabaceae families. This report extends the host range of SYMMoV to include the Solanaceae family, and extends the host range of PepGMV to include C. moschata, C. pepo and the Fabaceae Erythrina spp. This is the first report of a begomovirus (PepGMV)infecting chayote in the Western Hemisphere.
