A scoping review on tools and methods for trait prioritization in crop breeding programmes.

Trait prioritization studies have guided research, development and investment decisions for public-sector crop breeding programmes since the 1970s, but the research design, methods and tools underpinning these studies are not well understood. We used PRISMA-ScR (Preferred Reporting Items for Systematic review and Meta-Analysis Protocols) to evaluate research on trait ranking for major crops over the past 40 years (1980-2023). Data extraction and descriptive analysis on 657 papers show uneven attention to crops, lack of systematic sex disaggregation and regional bias. The lack of standardized trait data taxonomy across studies, and inconsistent research design and data collection practices make cross-comparison of findings impossible. In addition, network mapping of authors and donors shows patterns of concentration and the presence of silos within research areas. This study contributes to the next generation of innovation in trait preference studies to produce more inclusive, demand-driven varietal design that moves beyond trait prioritization focused on productivity and yield.

Economic Studies Reinforce Efforts to Safeguard Specialty Crops in the United States.

Pathogen-tested foundation plant stocks are the cornerstone of sustainable specialty crop production. They provide the propagative units that are used to produce clean planting materials, which are essential as the first-line management option of diseases caused by graft-transmissible pathogens such as viruses, viroids, bacteria, and phytoplasmas. In the United States, efforts to produce, maintain, and distribute pathogen-tested propagative material of specialty crops are spearheaded by centers of the National Clean Plant Network (NCPN). Agricultural economists collaborated with plant pathologists, extension educators, specialty crop growers, and regulators to investigate the impacts of select diseases caused by graft-transmissible pathogens and to estimate the return on investments in NCPN centers. Economic studies have proven valuable to the NCPN in (i) incentivizing the use of clean planting material derived from pathogen-tested foundation plant stocks; (ii) documenting benefits of clean plant centers, which can outweigh operating costs by 10:1 to 150:1; (iii) aiding the development of disease management solutions that are not only ecologically driven but also profit maximizing; and (iv) disseminating integrated disease management recommendations that resonate with growers. Together, economic studies have reinforced efforts to safeguard specialty crops in the United States through the production and use of clean planting material.

Design and characterization of immobilized biocatalyst with lipase activity onto magnetic magnesium spinel nanoparticles: A novel platform for biocatalysis.

Lipases (EC 3.1.1.3) are very used industrial enzymes but presents drawbacks such as lack of stability, and poor recyclability. Most of these obstacles can be solved by lipase immobilization. The objective of this work was evaluated to magnetic magnesium spinel nanoparticles as support for lipase immobilization by covalent bound. The techniques used for nanoparticles synthesis presented advantages in the size selection of the nanoparticles obtained (60-100 nm). The immobilization of Candida rugosa lipase (CRL) was optimized. The optimal conditions were determined to be pH 3.7, enzyme concentration of 1.1 mg/mL at 4 °C and an ionic strength of 100 mM. The CRL@MgFe2O4 activity obtained was 3.2 times over the starting conditions (4.03 U/mL). The immobilization of the lipase on Fe3O4 was evaluated and compared. The activity of the CRL@MgFe2O4 was 61% higher than CRL@Fe3O4 and 22% higher than free enzyme. CRL@MgFe2O4 improved the lipase stability at alkaline pH, hydrophilic solvent and high temperatures. The thermogravimetric analysis showed that this new biocatalyst was more stable compared to the free enzyme. Additionally, the immobilized lipase was recycled by magnetic force and used in ten catalysis cycles. The performance of the recycle was improved using butanol or Triton X 100 during washing. Finally, CRL@FeMg2O4 showed hydrolysis and synthesis activity. Thus, CRL@FeMg2O4 as a novel biocatalyst generation presents interesting properties for industrial applications.

[Psychosocial aspects in a cohort of vertically transmitted human immunodeficiency virus-infected adolescents]. / Aspectos psicosociales en una cohorte de adolescentes con infección por el virus de la inmunodeficiencia humana por transmisión vertical. NeuroCoRISpeS.

INTRODUCTION: Thanks to advances in antiretroviral treatment, children with HIV infections through vertical transmission have improved their life expectancy. However, new challenges have emerged. We propose this study in order to determine the psychosocial aspects and knowledge of infections in a cohort of adolescents with vertically transmitted HIV infections. METHODS: Patients with vertically-acquired HIV infection between 12 and 19 years old were included. Data were obtained through semi-structured interviews and a Strengths and Difficulties Questionnaire for emotional and behavioral disorders screening. RESULTS: We evaluated 96 patients (58% females) with a median age of 15 years (11-19.1) and a median age at diagnosis of 1.70 years (0-12.2). The median CD4 count was 626cells/mm(3) (132-998), and the viral load was<50cp/ml in 72% of patients. Among them, 90% attended school and 60% repeated at least one course. Although 81% of them knew of their diagnosis, only 30% understood their disease, with 18.2% having discussed it with friends. Six unwanted pregnancies occurred during the study period. Strengths and Difficulties Questionnaire showed hyperactivity risk in 33%. CONCLUSION: A high percentage of adolescents show difficulties in several areas (disease knowledge, peer relationship, school failure...) that can have an impact on their adult lives. Further studies are needed to evaluate their origin and development in depth, as well as interventions to modify this situation.

Meningitis bacteriana por Streptococcus pyogenes: revisión de la literatura / Bacterial meningitis due to Streptococcus pyogenes: literature review

Introducción: el Streptococcus pyogenes (S. pyogenes) es una etiología poco habitual de meningitis bacteriana a pesar de ser un germen que frecuentemente produce infecciones en otras localizaciones en la edad pediátrica. Material y métodos: se revisaron los casos de bacteriemia por S. pyogenes y los factores de riesgo asociados en la base de datos del Servicio de Microbiología del Hospital Universitario La Paz desde junio de 2002 a junio de 2012. Resultados: únicamente se encontró un caso de bacteremia por S. pyogenes asociado a meningitis, que se describe en este artículo. Conclusiones: a pesar de su baja incidencia, se debe tener en cuenta el S. pyogenes en el diagnóstico diferencial de meningitis bacterianas, especialmente en pacientes con factores de riesgo asociados (AU)

Introduction: Streptococcus pyogenes (S. pyogenes) is a rare cause of meningitis despite being a common source of pediatric infections in other sites. Material and methods: A search was performed of the pediatric patients with S. pyogenes bacteremia in the microbiology database of the Hospital Infantil La Paz from June 2002 until June 2012. Results: A single case of S. pyogenes meningitis was found and is reported in this article. Conclusions: Despite its low incidence, S. pyogenes should be considered in the differential diagnosis of meningitis, particularly in patients with associated risk factors (AU)

¿Es el hábito tabáquico un factor determinante en la lactancia materna? / Is the smoking habit a determining factor in breastfeeding?

En España, las tasas de lactancia son bajas respecto a lo recomendado por la OMS. La relación entre tabaquismo y lactancia sigue siendo incierta, pero parece dificultarla. El objetivo de este estudio es clarificar el estado actual de la evidencia sobre la influencia del tabaquismo en la lactancia materna. Material y métodos. Revisión bibliográfica en Cochrane Library en español, PubMed, Cuiden y SCielo de publicaciones previas al año 2000. Resultados. Fumar se asocia con menores tasas de inicio de la lactancia y con una menor duración de la misma. La nicotina influye negativamente en la producción de leche, pero los factores sociales parecen ser los más influyentes en el éxito de la lactancia. La lactancia en mujeres fumadoras es más segura que combinar tabaquismo con fórmula artificial. La intervención educativa para modificar las actitudes maternas parece favorecer la lactancia en mujeres fumadoras. Conclusiones. Se necesitan más investigaciones sobre los efectos de la lactancia cuando la madre es fumadora. La lactancia materna es la opción más beneficiosa incluso en mujeres fumadoras (AU)

Lactation rates in Spain are lower than WHO recommendation. The relationship between smoking and breastfeeding is still uncertain but it looks to make it difficult. The aim of this study is to clarify the evidence state about the smoking influence on breastfeeding. Methods. Evidence review was conducted in Cochrane Library, PubMed, Cuiden and SCielo databases. Publications from year 2000 were considered. Results. Smoking is associated with lower rates in breastfeeding initiation and duration. Nicotine has a negative effect on milk production, but social factors seem to be the most important in breastfeeding success. Lactation in smoking women is safer than the smoke exposition combined with formula. Educative interventions to modify maternal attitude seems to facilitate breastfeeding in smoking women. Conclusions. Further investigation about breastfeeding in smoking women is needed. Breastfeeding is the best option even in smoking mothers (AU)

Economic analysis of Mycobacterium avium subspecies paratuberculosis vaccines in dairy herds.

Johne's disease, or paratuberculosis, is a chronic infectious enteric disease of ruminants, caused by infection with Mycobacterium avium ssp. paratuberculosis (MAP). Given the absence of a fail-safe method of prevention or a cure, Johne's disease can inflict significant economic loss on the US dairy industry, with an estimated annual cost of over $200 million. Currently available MAP control strategies include management measures to improve hygiene, culling MAP serologic- or fecal-positive adult cows, and vaccination. Although the 2 first control strategies have been reported to be effective in reducing the incidence of MAP infection, the changes in herd management needed to conduct these control strategies require significant effort on the part of the dairy producer. On the other hand, vaccination is relatively simple to apply and requires minor changes in herd management. Despite these advantages, only 5% of US dairy operations use vaccination to control MAP. This low level of adoption of this technology is due to limited information on its cost-effectiveness and efficacy and some important inherent drawbacks associated with current MAP vaccines. This study investigates the epidemiological effect and economic values of MAP vaccines in various stages of development. We create scenarios for the potential epidemiological effects of MAP vaccines, and then estimate economically justifiable monetary values at which vaccines become economically beneficial to dairy producers such that a net present value (NPV) of a farm's net cash flow can be higher than the NPV of a farm using no control or alternative nonvaccine controls. Any vaccination with either low or high efficacy considered in this study yielded a higher NPV compared with a no MAP control. Moreover, high-efficacy vaccines generated an even higher NPV compared with alternative controls, making vaccination economically attractive. Two high-efficacy vaccines were particularly effective in MAP control and NPV maximization. One was a high-efficacy vaccine that reduced susceptibility to MAP infection. The other was a high-efficacy vaccine that had multiple efficacies on the dynamics of MAP infection and disease progress. Only one high-efficacy vaccine, in which the vaccine is targeted at reducing MAP shedding and the number of clinical cases, was not economically beneficial to dairy producers compared with an alternative nonvaccine control, when herds were highly infected with MAP.

[Patient-noninvasive mechanical ventilation interaction]. / Interacción paciente-ventilador en ventilación mecánica no invasiva.

Noninvasive mechanical ventilation is one more step in the treatment of patients with acute respiratory failure. In addition to gas exchange disorders, its primary indication to initiate it is the presence of signs of respiratory muscles fatigue. To assure successful mechanical ventilation, the ventilator and patient must be synchronized, that is, the effort the patient makes to start inspiration is recognized by the ventilator and it quickly delivers gas flow, that the flow provided by the ventilator adapts to the flow need of the patient during delivery of gas phase and that the ventilator recognizes the cessation of inspiratory activity by the patient, ends the delivery of gas and opens the expiratory valve to allow the patient expiration. This sequence of events, which seem so logical, is almost never achieved in the clinical practice, commonly observing some asynchrony in ventilated patients. The presence of patient-ventilator asynchrony leads to increased breathing work, which would lead to the failure of the main objective of ventilatory support, that is none other than decline in the patient's respiratory work.

Interacción paciente-ventilador en ventilación mecánica no invasiva / Patient-noninvasive mechanical ventilation interaction

La ventilación mecánica no invasiva constituye un escalón más del tratamiento del paciente en situación de fallo respiratorio agudo. Además de los trastornos del intercambio de gases, la indicación principal para iniciarla la constituye la presencia de signos de fatiga de los músculos respiratorios. Para que la ventilación mecánica tenga éxito es fundamental que ventilador y paciente estén sincronizados, es decir, que el esfuerzo que el enfermo hace para iniciar la inspiración sea reconocido por el ventilador y este entregue rápidamente un flujo de gas, que el flujo aportado por el ventilador se adapte a la necesidad de flujo del paciente durante la fase de entrega de gas, y que el ventilador reconozca el cese de la actividad inspiratoria del paciente, finalice la entrega de gas y abra la válvula espiratoria para permitir la espiración del paciente. Esta secuencia de hechos, que parecen tan lógicos, casi nunca se consigue en la práctica clínica, siendo habitual observar en los pacientes ventilados algún tipo de asincronía. La presencia de desadaptación o asincronía paciente-ventilador conduce invariablemente a un aumento del trabajo respiratorio, lo que hará fracasar el objetivo fundamental del soporte ventilatorio, que no es otro que la disminución del trabajo respiratorio del paciente(AU)

[Pneumococcal conjugate vaccine failure in HIV-infected child. Clinical case]. / Fallo de la vacuna antineumocócica conjugada en un niño VIH positivo. A propósito de un caso.

Despite appropriate antimicrobial therapy and vaccination, invasive pneumococcal infections remain associated with significant mortality, especially in selected high-risk groups (asplenic, humoral immunity deficient patients, etc.). We present a 13-year-old caucasian boy with HIV infection (vertical transmission). He received treatment with highly-active antiretroviral therapy (amprenavir, lamivudine and zidovudine) and vaccination with 23-valent vaccine (6 years old) and 7-valent pneumococcal conjugate vaccine (10 years old). His CD4 count and his viral load at these times were 2,063/microl and 13461 cop/ml, when he was 6 years old and 1,315/microl and 32400 cop/ml when he was 10 years old, respectively. The latest CD4 count (1,000/microl) and his viral load (3800 cop/ml) confirmed satisfactory control of the disease. He was referred to our emergency department presenting with fever, head and stomach-ache and vomiting. In the following hours his condition continued to deteriorate and depressed level of consciousness and meningismus were observed. Streptococcus pneumoniae, serotype 18 C, was detected in blood and cerebrospinal fluid cultures. Despite appropriate treatment with antibiotics (cefotaxime and vancomycin) and anti-oedema medications, brain-death was confirmed 24 hours after his admittance.

Fallo de la vacuna antineumocócica conjugada en un niño VIH positivo. A propósito de un caso / Pneumococcal conjugate vaccine failure in HIV-infected child

La infección neumocócica sigue asociada con una importante mortalidad, especialmente en grupos de riesgo (esplenectomizados, déficit de la inmunidad humoral, etc.) a pesar de vacunas y antibióticos adecuados. Presentamos a un niño de 13 años VIH positivo por transmisión vertical tratado con triple terapia (amprenavir, lamivudina y zidovudina). Fue vacunado con vacuna 23-valente a los 6 años y conjugada heptavalente a los 10 años de edad. El recuento de células CD4 y su carga viral a los 6 años eran de 2.063/μl y 13.461 copias/ml, respectivamente. A los 10 años el recuento de CD4 y su carga viral eran de 1.315/μl y 32.400 copias/ml, respectivamente. El último recuento de CD4 (1.000/μl) y la carga viral (3.800 copias/ml) confirmaban un buen control de la enfermedad 15 días antes del ingreso. Acude a urgencias por fiebre, dolor abdominal y vómitos. Hay un progresivo deterioro del nivel de conciencia y signos meníngeos. En el hemocultivo y en el cultivo de LCR crece Streptococcus pneumoniae serotipo 18C, y es tratado con cefotaxima y vancomicina, así como medidas antiedema cerebral, pero evoluciona a muerte cerebral en 24 h (AU)

[Late onset group B Streptococcus infection: 7 year experience in a tertiary hospital (2000-2006)]. / Infección tardía por estreptococo del grupo B: experiencia en un hospital de tercer nivel (2000-2006).

INTRODUCTION: Group B Streptococcus (GBS) is a major cause of neonatal infection. Two forms of the disease have been described according to the age of presentation: early, beginning in the first 6 days of life, and late, occurring from day 7 up to 3 months of age. OBJECTIVES: To analyze the epidemiology of the late onset form of GBS disease in a tertiary hospital after implementing preventive strategies aimed to reduce the rate of vertical transmission. METHODS: We retrospectively reviewed the medical records of children diagnosed with late GBS infection between January 2000 and December 2006. Diagnostic criteria included a positive blood culture and/or a positive cerebrospinal fluid (CSF) culture for GBS in any patient aged between 7 and 89 days. RESULTS: 24 patients were identified, most of them presenting after January 2005. Median age was 36.2 days (range 9 to 81). GBS isolates in blood were found in 20 patients, 1 in CSF and 3 in both. Most frequently children presented with fever (70.8 %) and irritability (54.1 %). Five patients (20.8 %) had a cellulitis-adenitis syndrome. Cefotaxime and ampicillin were the most often used antibiotic combination. No ampicillin resistances were found. CONCLUSIONS: The number of children with late GBS disease has increased in our center. Accordingly, the recent recommendations for the prevention of perinatal GBS vertical transmission were not effective for reducing late GBS infection. This may be due to horizontal infections from maternal sources, community or cross infections. It is important to maintain clinical suspicion of late GBS infection and start early antibiotic treatment.

[Increase in the incidence of bacterial pneumonia between 2001 and 2004]. / Incremento de la incidencia de neumonía bacteriana entre 2001 y 2004.

AIM: To study patients with typical community-acquired pneumonia (CAP) admitted to our hospital between 2001 and 2004 in order to analyze the incidence of this disease in our health area during this period. METHODS: A retrospective study was performed of patients with CAP admitted to our hospital from 2001 to 2004. Only those patients who fulfilled the criteria for typical pneumonia of possible bacterial origin based on clinical and radiological features and laboratory data were included. The annual incidence rates of CAP were analyzed using demographic data from our health area and from all children admitted to the infectious diseases unit of our hospital during this period. RESULTS: During the study period, 569 children were diagnosed with typical CAP: 116 in 2001, 133 in 2002, 154 in 2003 and 166 in 2004. The incidence rate was 1.3 cases/1,000 children under 14 years old/year in 2001, 1.51 in 2002, 1.69 in 2003 and 1.72 in 2004. These findings represent an increment of 25% in the incidence per 1,000/children/year and an increment of 53% in the incidence per 100 children admitted to our unit. Blood cultures were performed before antibiotic therapy was administered in 487 patients and were positive in 22 (4.5%). Streptococcus pneumoniae was isolated in 21 patients and Streptococcus pyogenes in one. Chest radiographs revealed lobar consolidation in 95% of the patients and 15 % developed pleural effusion. CONCLUSIONS: Cases of CAP of probable pneumococcal etiology increased in our health area during the study period. The number of complicated cases also increased.

[Staphylococcal scalded skin syndrome]. / Síndrome de escaldadura estafilocócica.

INTRODUCTION: Staphylococcal scalded skin syndrome is a rare disease caused by Staphylococcus aureus that produces exfoliative toxins. There are few epidemiological data in our environment. PATIENTS AND METHODS: We present an observational cohort study. We review the cases of staphylococcal scalded skin syndrome monitored at La Paz Children Hospital during the last ten years (January 1997 to December 2006). RESULTS: We obtained 26 patients, 7 in the first 5 years and 19 more in the following years. The mean age at diagnosis was 19 months. Four cases (15%) occurred during the neonatal period. Sixty-seven percent of the cases were diagnosed during spring and summer. Main clinical signs were: erythroderma with blisters and posterior desquamation (100%), perioral fissures (54%), fever (46%), conjunctivitis (42%) and palpebral edema (31%). No significant increases in leukocytes (mean: 11,341/.l) or C-reactive protein (mean: 9 mg/l) were found on blood analysis. Diagnosis was made by clinical findings. S. aureus was isolated in nasal or conjunctival samples on 59% of cases. All strains were sensitive to cloxacillin, clindamycin and vancomycin. The patients were treated with cloxacillin with good progress. CONCLUSIONS: Staphylococcal scalded skin syndrome seems to be more common in the last few years. It must be suspected in children with acute erythroderma and perioral or conjunctival lesions. Treatment with cloxacillin leads to healing without sequelae.

Incremento de la incidencia de neumonía bacteriana entre 2001 y 2004 / Increase in the incidence of bacterial pneumonia between 2001 and 2004

Objetivo: Estudiar los pacientes ingresados en nuestro hospital por neumonía típica adquirida en la comunidad (NAC) en los últimos 4 años y analizar la incidencia en este período. Métodos: Se seleccionaron retrospectivamente todas las NAC ingresadas en nuestro hospital entre los años 2001 y 2004. Se analizaron exclusivamente aquellas que cumplían criterios clínico-analítico-radiológicos de neumonía típica de posible origen bacteriano. Se analiza la incidencia de NAC según los datos de población de nuestra área sanitaria y del número de ingresos totales en la unidad de enfermedades infecciosas. Resultados: Se diagnosticaron un total de 569 NAC que cumplían criterios de bacteriana: 116 casos en 2001, 133 casos en 2002, 154 casos en 2003 y 166 casos en 2004. La incidencia fue de 1,38 casos/1.000 niños < 14 años de edad/año en 2001, 1,51 en 2002, 1,69 en 2003 y 1,72 en 2004. Esto supone un incremento de la incidencia del 25 % por 1.000 niños/año en nuestra área sanitaria y un incremento de la incidencia del 53 % por 100 ingresos en la unidad. Se realizó hemocultivo antes de la antibioterapia en 487 casos, de los cuales fueron positivos 22 (4,5 %), 21 para Streptococcus pneumoniae y 1 para Streptococcus pyogenes. El 95 % de los pacientes presentaba en la radiografía de tórax una imagen de consolidación. El 15 % de los pacientes tuvo derrame pleural. Conclusiones: En los últimos años hemos observado un aumento del número de casos de neumonía de posible origen neumocócico en España, al mismo tiempo que también se ha producido un incremento de los casos complicados (AU)
