High-energy forage feeding diets and body condition on the finishing of cull dairy cows

Combinations of two high-energy forage finishing diets and two initial body condition scores (BCSs) in a 2 × 2 factorial experimental design were evaluated on cull Holstein–Friesian (HF) cows to improve animal performance and carcass characteristics, aimed at achieving proper fatness and conformation scores (a minimum of ‘4’ and ‘O’, respectively) required for the marketing of high-value loin steaks. The two finishing diets were (i) conventional maize silage complemented with concentrate diet and (ii) wet maize ear silage (pastone) complemented with dry-herbage diet. The two initial body condition levels were (i) low BCS 5 (HBCS). The HBCS animals had the greatest potential to respond to the finishing diets. They needed a smaller total feed intake (TFI) and a shorter finishing period (FP) to meet the marketing requirements. The average feed budgets necessary to finish cull dairy cows and to achieve the minimum scores ‘4’ and ‘O’ of carcass classification were 2.31 and 3.61 t of dry matter (DM)/cow for HBCS and LBCS animals, respectively, while the FP lasted an average of 143 and 224 days for HBCS and LBCS animals, respectively. With regard to the two feeding diets, we found no differences for TFI, carcass characteristics and loin muscle features, such as weight, diameter and intramuscular fatResearch partially funded by the project 07MRU001CT of theConsellería de Investigación, Desarrollo e Innovación from Xuntade Galicia, SpainS

Lycopene Supplementation for Patients Under Cancer Therapy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Introduction: Lycopene supplementation has been considered potentially useful as an adjuvant cancer therapy according to its anticancer properties. The present study aimed to investigate the effects of lycopene supplementation on outcome improvement in patients with cancer therapy. As a secondary aim, we conducted a meta analysis to investigate the efficacy of lycopene supplementation on circulating lycopene concentration in patients with cancer therapy.Methods: A systematic and comprehensive search was performed in electronic databases, including PubMed, Cochrane Central Register of Controlled Trials, Web of Science, SCOPUS, EMBASE, MedNar, and OpenGrey up to March 2023. The inclusion criteria were randomized controlled trials conducted on patients under cancer therapy (i.e., radiotherapy, chemotherapy, surgery, etc.) supplementing with lycopene. Data extraction and analysis: two different evaluators screened and collected literature independently. Information regarding the study design, participants, intervention, and dependent outcomes was extracted, and the bias of the study was assessed. Additionally, separate random-effect meta-analyses were performed to examine the effects of lycopene supplementation on circulating lycopene concentration in patients under cancer therapy.Results: The initial search retrieved 7 565 articles of which eight met the inclusion criteria. Lycopene supplementation did not modify cancer hallmarks in these studies. However, despite the heterogeneity between studies, we show that, compared with control, lycopene supplementation had moderate effects on circulating lycopene concentration in patients under cancer therapy (pooled mean difference, 0.1361; 95% CI [0.0574; 0.2148], P = .0007).Conclusions: Our study shows that lycopene supplementation does not modify the main hallmarks of cancer, but it increases circulating lycopene concentration in patients under cancer therapy, which could have a positive impact on potential clinical and molecular outcomes in cancer patients.Spanish Government FPU19/01609University of Granada Plan Propio de Investigacion 2016-Excellence actions: Unit of Excellence on Exercise and Healt

Identidad de género y cuidados intensivos: influencia de la masculinidad y la feminidad en la percepción de los cuidados enfermeros

Introducción: La enfermería ha sido fundamentalmente un trabajo de mujeres. El incremento en la incorporación de hombres a la enfermería nos hace reflexionar en torno a la cuestión de si existen diferentes formas de expresar y practicar una profesión en relación al género. Objetivo: Describir si existen diferentes maneras de percibir y valorar el trabajo en la UCI desde una perspectiva de género. Metodología: Estudio cualitativo fenomenológico. Muestra: 6 enfermeros y 6 enfermeras de la UCI del HUB Recogida de datos: Entrevista semi-estructurada en profundidad. Análisis de contenido. Resultados: Los enfermeros describen el trabajo en la UCI en términos de autonomía en las decisiones y competencia profesional; reivindican su identidad como enfermeros y destacan el bajo reconocimiento social que se hace de la profesión; priorizan más la responsabilidad en la toma de decisiones que el resultado final y valoran la satisfacción familiar en términos de prestigio y competencia. Son más prácticos. Las enfermeras califican el trabajo en términos de control y seguimiento en la evolución del enfermo; destacan más el resultado final del cuidado y valoran la satisfacción en términos de relación de confianza y calidez asistencial. Son más detallistas. Conclusiones: Existen diferencias en la manera de calificar el trabajo en la UCI, en la valoración de la identidad profesional, el comportamiento en el desarrollo de los cuidados de enfermería y en la percepción de la satisfacción familiar. No se observan diferencias en relación al abordaje en la resolución de problemas con la tecnología

Past and recent effects of livestock activity on the genetic diversity and population structure of native guanaco populations of arid patagonia

Extensive livestock production and urbanization entail modifications of natural landscapes, including installation of fences, development of agriculture, urbanization of natural areas, and construction of roads and infrastructure that, together, impact native fauna. Here, we evaluate the diversity and genetic structure of endemic guanacos (Lama guanicoe) of the Monte and Patagonian Steppe of central Argentina, which have been reduced and displaced by sheep ranching and other impacts of human activities. Analyses of genetic variation of microsatellite loci and d-loop revealed high levels of genetic variation and latitudinal segregation of mitochondrial haplotypes. There were indications of at least two historical populations in the Monte and the Patagonian Steppe based on shared haplotypes and shared demographic history among localities. Currently, guanacos are structured into three groups that were probably reconnected relatively recently, possibly facilitated by a reduction of sheep and livestock in recent decades and a recovery of the guanaco populations. These results provide evidence of the genetic effects of livestock activity and urbanization on wild herbivore populations, which were possibly exacerbated by an arid environment with limited productive areas. The results highlight the importance of enacting conservation management plans to ensure the persistence of ancestral and ecologically functional populations of guanacos.Fil: Mesas, Andrés.

Curing of Plasmid pXO1 from Bacillus anthracis Using Plasmid Incompatibility

The large plasmid pXO1 encoding the anthrax toxin is important for the virulence of Bacillus anthracis. It is essential to cure pXO1 from B. anthracis to evaluate its role in the pathogenesis of anthrax infection. Because conventional methods for curing plasmids (e.g., curing agents or growth at elevated temperatures) can induce mutations in the host chromosomal DNA, we developed a specific and reliable method to eliminate pXO1 from B. anthracis using plasmid incompatibility. Three putative replication origins of pXO1 were inserted into a temperature-sensitive plasmid to generate three incompatible plasmids. One of the three plasmids successfully eliminated the large plasmid pXO1 from B. anthracis vaccine strain A16R and wild type strain A16. These findings provided additional information about the replication/partitioning of pXO1 and demonstrated that introducing a small incompatible plasmid can generate plasmid-cured strains of B. anthracis without inducing spontaneous mutations in the host chromosome

J-shaped relationship between habitual coffee consumption and 10-year (2002–2012) cardiovascular disease incidence:the ATTICA study

Purpose: The purpose of this work was to evaluate the association between coffee consumption and 10-year cardiovascular disease (CVD) incidence in the ATTICA study, and whether this is modified by the presence or absence of metabolic syndrome (MetS) at baseline. Methods: During 2001–2002, 3042 healthy adults (1514 men and 1528 women) living in the greater area of Athens were voluntarily recruited to the ATTICA study. In 2011–2012, the 10-year follow-up was performed in 2583 participants (15% of the participants were lost to follow-up). Coffee consumption was assessed by a validated food-frequency questionnaire at baseline (abstention, low, moderate, heavy). Incidence of fatal or non-fatal CVD event was recorded using WHO-ICD-10 criteria and MetS was defined by the National Cholesterol Education Program Adult Treatment panel III (revised) criteria. Results: Overall, after controlling for potential CVD risk factors, the multivariate analysis revealed a J-shaped association between daily coffee drinking and the risk for a first CVD event in a 10-year period. Particularly, the odds ratio for low (250 ml/day), compared to abstention, were 0.44 (95% CI 0.29–0.68), 0.49 (95% CI 0.27–0.92) and 2.48 (95% CI 1.56–1.93), respectively. This inverse association was also verified among participants without MetS at baseline, but not among participants with the MetS. Conclusions: These data support the protective effect of drinking moderate quantities of coffee (equivalent to approximately 1–2 cups daily) against CVD incidents. This protective effect was only significant for participants without MetS at baseline

Standardized postnatal management of infants with congenital diaphragmatic hernia in Europe: The CDH EURO Consortium Consensus - 2015 Update

In 2010, the congenital diaphragmatic hernia (CDH) EURO Consortium published a standardized neonatal treatment protocol. Five years later, the number of participating centers has been raised from 13 to 22. In this article the relevant literature is updated, and consensus has been reached between the members of the CDH EURO Consortium. Key updated recommendations are: (1) planned delivery after a gestational age of 39 weeks in a high-volume tertiary center; (2) neuromuscular blocking agents to be avoided during initial treatment in the delivery room; (3) adapt treatment to reach a preductal saturation of between 80 and 95% and postductal saturation >70%; (4) target PaCO2 to be between 50 and 70 mm Hg; (5) conventional mechanical ventilation to be the optimal initial ventilation strategy, and (6) intravenous sildenafil to be considered in CDH patients with severe pulmonary hypertension. This article represents the current opinion of all consortium members in Europe for the optimal neonatal treatment of CDH

Understanding the risk and protective factors associated with obesity amongst Libyan adults - a qualitative study

BACKGROUND: There are a range of multifaceted behavioural and societal factors that combine to contribute to the causes of obesity. However, it is not yet known how particularly countries' cultural norms are contributing to the global obesity epidemic. Despite obesity reaching epidemic proportions in Libya, since the discovery of oil in 1959, there is a lack of information about obesity in Libyan adults. This study sought to explore the views of key informants about the risk and protective factors associated with obesity among Libyan men and women. METHODS: A series of qualitative semi-structured interviews were conducted with Libyan healthcare professionals and community leaders. RESULTS: Eleven main themes (risk and protective factors) were identified, specifically: socio-demographic and biological factors, socioeconomic status, unhealthy eating behaviours, knowledge about obesity, social-cultural influences, Libya's healthcare facilities, physical activity and the effect of the neighbourhood environment, sedentary behaviour, Libyan food-subsidy policy, and suggestions for preventing and controlling obesity. CONCLUSIONS: Key recommendations are that an electronic health information system needs to be implemented and awareness about obesity and its causes and consequences needs to be raised among the public in order to dispel the many myths and misconceptions held by Libyans about obesity. The current political instability within Libya is contributing to a less-active lifestyle for the population due to security concerns and the impact of curfews. Our findings have implications for Libyan health policy and highlight the urgent need for action towards mitigating against the obesity epidemic in Libya
