A multifaceted clinical decision support intervention to improve adherence to thromboprophylaxis guidelines

Background Venous thromboembolism is a potentially fatal complication of hospitalisation, affecting approximately 3% of non-surgical patients. Administration of low molecular weight heparins to the appropriate patients adequately decreases venous thromboembolism incidence, but guideline adherence is notoriously low. Objective To determine the effect of a multifaceted intervention on thromboprophylaxis guideline adherence. The secondary objective was to study the effect on guideline adherence specifically in patients with a high venous thromboembolism risk. As an exploratory objective, we determined how many venous thromboembolisms may be prevented. Setting A Dutch general teaching hospital. Method A prospective study with a pre- and post-intervention measurement was conducted. A multifaceted intervention, consisting of Clinical Decision Support software, a mobile phone application, monitoring of duplicate anticoagulants and training, was implemented. Guideline adherence was assessed by calculating the Padua prediction and Improve bleeding score for each patient. The number of preventable venous thromboembolisms was calculated using the incidences of venous thromboembolism in patients with and without adequate thromboprophylaxis and extrapolated to the annual number of admitted patients. Main outcome measure Adherence to thromboprophylaxis guidelines in pre- and post-intervention measurements. Results 170 patients were included: 85 in both control and intervention group. The intervention significantly increased guideline adherence from 49.4 to 82.4% (OR 4.78; 95%CI 2.37-9.63). Guideline adherence in the patient group with a high venous thromboembolism risk also increased significantly from 54.5 to 84.3% (OR 2.46; 95%CI 1.31-4.62), resulting in the potential prevention of +/- 261 venous thromboembolisms per year. Conclusions Our multifaceted intervention significantly increased thromboprophylaxis guideline adherence

Construction of orthonormal wavelet-like bases

A general method for constructing wavelet-like bases in a Hilbert space H starting from any orthonormal basis in H and any periodic orthonormal wavelet basis is presented. With this method we can take advantage of the characteristics of both types of bases to obtain orthonormal wavelet-like bases that are suitable to represent functions and operators efficiently.Fil: Morillas, Patricia Mariela.

Paternal peripartum depression:emerging issues and questions on prevention, diagnosis and treatment. A consensus report from the cost action Riseup-PPD

Introduction: Paternal peripartum depression (P-PPD) is a serious and understudied public health problem associated with impaired family functioning and child development. The lack of recognition of P-PPD may result in limited access to both information and professional help. Objective: The aim of the study was to review studies on paternal peripartum depression and to identify issues and questions where future research and theory formation are needed. Methods: A literature search for systematic reviews, meta-analyses and primary studies was conducted using PubMed, Web of Science, Embase, Scopus, Medline, PsychInfo and Informit databases. Key results within the retrieved articles were summarised and integrated to address the review objectives. Results: Based on the literature, the knowledge related to prevalence, screening, risk factorsunique to fathers, management strategies and outcomes of P-PPD is lacking. Currently, there is no consensual understanding of the definition of P-PPD and recommendations for dealing with P-PPD. Limited data were available regarding the barriers preventing fathers from accessing support systems. Conclusion: Emerging issues that need to be addressed in future research include: P-PPD definition and pathogenetic pathways; prevention strategies and assessment tools; self-help seeking and engagement with interventions; the cost-effectiveness of P-PPD management; needs of health professionals; effect on child development, and public awareness. Future studies and clinical practice should account the complexities that may arise from the father’s perceptions of health care services. Results from this review highlights the critical issues on how to plan, provide and resource health services, to meet the health needs of fathers.</p

Maternal health agency in women with a low socioeconomic status:a qualitative study

Background: Health agency refers to one’s capacity to form health-related goals, experience control, and possess the means to pursue them. Low socioeconomic status (SES) is linked to impaired health agency and increased risk of adverse pregnancy outcomes, potentially due to a reduced tendency to seek care. Better healthcare availability may not improve their pregnancy outcomes, and therefore improved understanding of maternal health agency is paramount. Methods: Semi-structured interviews were conducted with 15 participants who either had children or desired to have them. Low SES was determined by neighborhood median income and educational attainment. A thematic content analyses was conducted. Results: Two themes emerged: 1) Origin and development of personal goals, and 2) Awareness and competence. Participant’s goals stemmed from cultural norms, personal narratives, and intuition. Integrated goals were those participants valued highly, were aware of, and strived for. Four subthemes were identified in goal-awareness and competence. Internal conflict due to discrepancies between goals and behavior resulted in the need to balance the burdens and benefits of behavior change. Conclusion: Maternal health agency is a modifiable outcome dependent on goal-awareness and various factors. Impaired agency seemed to stem from lack of goal-awareness rather than an inability to meet established pillars.</p

Modelación del frijol en Latinoamérica: Estado del arte y base de datos para parametrización

Frijol común (Phaseolus vulgaris L.) es la leguminosa de grano para consumo humano de mayor producción en el mundo, y es nativo de las Américas, donde juega un papel importante en la dieta. Los ambientes donde se cultiva el frijol varían desde zonas tropicales hasta alta montaña, con diversos hábitos de crecimiento (arbustivo determinado, arbustivo indeterminado, y voluble), y en sistemas de producción desde los tradicionales hasta los altamente tecnificados. Los esfuerzos en modelaje, por tanto, deben empezar desde identificar el tipo de frijol y el sistema objetivo. El frijol es muy sensible al estrés abiótico, hecho que ha animado el modelaje de su posible respuesta bajo escenarios de cambio climático. Se llevó a cabo una revisión de literatura para identificar quince ejercicios de modelaje ejecutados en América Latina, abarcando estudios de crecimiento (tazas de producción de nudos y área foliar), fenología, y de rendimiento. Los modelos empleados en dichos estudios incluyen EcoCrop, CROPGRO-DRYBEAN (implementado en la plataforma DSSAT), y en un caso cada uno, Maxent y CLIMEX. Se describen cuatro estudios en detalle: en los dos países de mayor producción en el mundo (Brasil y México), y en Centroamérica como región altamente vulnerable al cambio climático. Estos estudios concuerdan que la productividad del frijol podría sufrir serios efectos negativos en el transcurso del Siglo XXI a raíz del cambio climático. Finalmente, se informa sobre un ejercicio reciente de recopilar datos históricos de ensayos de frijol en Latinoamérica para alimentar futuros esfuerzos de modelaje. Common bean (Phaseolus vulgaris L.) is the grain legume of greatest volume of production for direct human consumption, and is native to the Americas where it plays an important role in the diet of consumers. Bean is cultivated in environments from lowland tropical areas to high mountainous zones; with growth habits ranging from determinate bush, to indeterminate bush, to climbing types; and in production systems varying from traditional low input agriculture to highly technified systems. As such, efforts at modelling should focus on a specific plant type and production system. Bean is very sensitive to abiotic stress, a fact that has motivated modelling of its response in light of the dangers of climate change. A review of literature was carried out revealing fifteen studies in Latin America considering different aspects of plant growth (rates of node and leaf area production), phenology, and yield. Models employed include EcoCrop, CROPGRO (a module within the DSSAT cropping system model), and in one instance each, Maxent and CLIMEX. Three studies in particular are detailed: in the two countries of greatest production in the world (Brazil and Mexico), and one study in Central America as a region under direct threat of climate change. These three studies confirm that bean productivity will likely suffer severe negative effects in the course of the 21st century, as a result of climate change. A recent effort has compiled data from historical yield trials in Latin America as a resource for future modelling efforts.JRC.D.5-Food Securit

Diagnosis of peripartum depression disorder:A state-of-the-art approach from the COST Action Riseup-PPD

Background: Peripartum depression (PPD) is a major depression disorder (MDD) episode with onset during pregnancy or within four weeks after childbirth, as defined in DSM-5. However, research suggests that PPD may be a distinct diagnosis. The goal of this study was to summarize the similarities and differences between PPD and MDD by synthesizing the current research on PPD diagnosis concerning different clinical features and give directions for improving diagnosis of PPD in clinical practice. Methods: To lay the groundwork for this narrative review, several databases were searched using general search phrases on PPD and its components of clinical diagnosis. Results: When compared to MDD, peripartum depression exhibits several distinct characteristics. PPD manifests with a variety of symptoms, i.e., more anxiety, psychomotor symptoms, obsessive thoughts, impaired concentration, fatigue and loss of energy, but less sad mood and suicidal ideation, compared to MDD. Although PPD and MDD prevalence rates are comparable, there are greater cross-cultural variances for PPD. Additionally, PPD has some distinct risk factors and mechanisms such as distinct ovarian tissue expression, premenstrual syndrome, unintended pregnancy, and obstetric complications. Conclusion: There is a need for more in-depth research comparing MDD with depression during pregnancy and the entire postpartum year. The diagnostic criteria should be modified, particularly with (i) addition of specific symptoms (i.e., anxiety), (ii) onset specifier extending to the first year following childbirth, (iii) and change the peripartum onset specifier to either “pregnancy onset” or “postpartum onset”. Diagnostic criteria for PPD are further discussed.</p

A diagnostic evaluation of single screen testing for malaria in the returning traveler: A large retrospective cohort study

From Wiley via Jisc Publications RouterHistory: received 2020-10-02, rev-recd 2020-12-14, accepted 2021-01-15, pub-electronic 2021-02-27, pub-print 2021-07Article version: VoRPublication status: PublishedAbstract: Background: Screening for malaria in the returning traveler has often required repeat testing; however, audit data suggest that patients have not been reattending. We sought to ascertain if this was safe by examining the diagnostic efficacy of a single screen consisting of a rapid diagnostic test (RDT) and a thin film. Methods: We conducted a retrospective cohort study of patients with suspected malaria who attended in the past 5 years from two large teaching hospitals. We assessed the diagnostic accuracy of a single screen, reporting measures of sensitivity and specificity. To establish a reference standard, we cross‐linked data with the national malaria registry held at Public Health England and regional centers. Results: The cohort consisted of 1365 patients, of whom 33 opted out of the research and one did not have a complete initial screen. Of those 1331 screens there were 74 cases of Plasmodium falciparum (prevalence of 5.6%) and 104 of any malaria species (prevalence of 7.8%). Sensitivity for the detection of P. falciparum was 100.00% (95% confidence interval [CI] = 95.1 to 100), with a specificity of 99.4% (95% CI = 98.9 to 99.8). For the detection of any species of malaria the sensitivity was slightly lower due to the presence of one false negative; sensitivity was 99.0% (95% CI = 94.8 to 100) and specificity was 99.5% (95% CI = 98.9 to 99.8). Conclusions: A single thin film and RDT is likely to be sufficient as a first screen for falciparum malaria in the returning traveler with important caveats. For those sent home from emergency departments, appropriate safety netting must be provided. Further prospective study is required to investigate this approach

The prognostic value of emergency department measured hypertension: A systematic review and meta‐analysis

From Wiley via Jisc Publications RouterHistory: received 2021-03-25, rev-recd 2021-06-07, accepted 2021-06-15, pub-electronic 2021-09-22Article version: VoRPublication status: PublishedFunder: Royal College of Emergency Medicine; Id: http://dx.doi.org/10.13039/501100007566Funder: National Institute of Health Research (UK)Abstract: Objectives: The objective was to assess the prognostic value of hypertension detected in the emergency department (ED). Methods: The ED presents a unique opportunity to predict long‐term cardiovascular disease (CVD) outcomes with its potential for high‐footfall, and large‐scale routine data collection applied to underserved patient populations. A systematic review and meta‐analyses were conducted to assess the prognostic performance and feasibility of ED‐measured hypertension as a risk factor for long‐term CVD outcomes. We searched MEDLINE and Embase databases and gray literature sources. The target populations were undifferentiated ED patients. The prognostic factor of interest was hypertension. Feasibility outcomes included prevalence, reliability, and follow‐up attendance. Meta‐analyses were performed for feasibility using a random effect and exact likelihood. Results: The searches identified 1072 studies after title and abstract review, 53 studies had their full text assessed for eligibility, and 26 studies were included. Significant heterogeneity was identified, likely due to the international populations and differing study design. The meta‐analyses estimate of prevalence for ED‐measured hypertension was 0.31 (95% confidence interval 0.25–0.37). ED hypertension was persistent outside the ED (FE estimate of 0.50). The proportion of patients attending follow‐up was low with an exact likelihood estimate of 0.41. Three studies examined the prognostic performance of hypertension and demonstrated an increased risk of long‐term CVD outcomes. Conclusion: Hypertension can be measured feasibly in the ED and consequently used in a long‐term cardiovascular risk prediction model. There is an opportunity to intervene in targeted individuals, using routinely collected data

Application of genomic tools to avocado (Persea americana) breeding : SNP discovery for genotyping and germplasm characterization

Avocado (Persea americana) is an important tropical and subtropical fruit tree crop. Traditional tree breeding programs face the challenges of long generation time and significant expense in land and personnel resources. Avocado selection and breeding can be more efficient and less expensive through the development of molecular markers for the estimation of germplasm genetic diversity, marker-assisted selection (MAS), and creation of linkage maps. Two important breeding resources, the world's two largest avocado mapping populations and an extensive germplasm collection, are housed at the USDA-ARS Subtropical Horticulture Research Station (SHRS) in Miami, Florida. However, to use these resources to their greatest advantage, many thousands of genetic markers are necessary. Here, we describe the development of the first set of avocado genetic markers based on single-nucleotide polymorphism (SNP) variation in expressed genes. RNA sequencing was used both to build a reference transcriptome from 'Hass', the most widely grown avocado cultivar worldwide, and to identify SNPs by alignment of RNA sequences from the mapping population parents to the ˈHassˈ transcriptome. This study provides a new genomic tool for the avocado community that can be used to assess the genetic diversity of avocado germplasm worldwide and to optimize avocado breeding and selection programs by complementing traditional breeding methods with molecular approaches, thus increasing the efficiency of avocado genetic improvement.http://www.elsevier.com/locate/scihortiam2019BiochemistryForestry and Agricultural Biotechnology Institute (FABI)GeneticsMicrobiology and Plant Patholog
