Nerve growth factor from seminal plasma origin (spβ-NGF) increases CL vascularization and level of mRNA expression of steroidogenic enzymes during the early stage of Corpus Luteum development in llamas. Theriogenology 2017; 103:69-75. [PMID: 28779611 DOI: 10.1016/j.theriogenology.2017.07.041] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2017] [Revised: 07/17/2017] [Accepted: 07/27/2017] [Indexed: 11/29/2022]
Abstract
The objectives of the study were to determine the effect of seminal plasma β-NGF on Corpus Luteum morphology and function and level of mRNA expression of steroidogenic enzymes. Llamas were assigned (n = 12/per group) to receive an intramuscular dose of: (a) 1 ml phosphate buffered saline (PBS), (b) 5 μg gonadorelin acetate (GnRH), or (c) 1.0 mg of purified llama spβ-NGF. Ovaries were examined by transrectal B-mode ultrasonography from treatment to ovulation (Day 0 = treatment). B mode/Power Doppler ultrasonography and blood samples collection were performed at Days 4, 8 and 10 (n = 3 llamas per treatment group/per time point) to determine CL diameter, vascularization and plasma progesterone concentration respectively. Plasma progesterone concentration was analyzed in all llamas at Day 0. Then females were submitted to ovariectomy at Days 4, 8 and 10 (n = 3 llamas/treatment/time), CL was removed to determine vascular area, proportion of luteal cells and CYP11A1/P450scc and STAR expression by RT-PCR. Ovulation was similar between llamas treated with GnRH or spβ-NGF and CL diameter did not differ between GnRH or spβ-NGF groups by Day 4, 8 or 10. Vascularization area of the CL was higher (P < 0.01) in llamas from the spβ-NGF than GnRH-treated group by Day 4 and 8. Plasma progesterone concentration was higher (P < 0.05) in llamas from the spβ-NGF compared to females of GnRH group by Day 4 and 8. The proportion of small and large luteal cells did not differ between GnRH or spβ-NGF groups by Day 8. CYP11A1/P450scc was upregulated 3 folds at day 4 and 10 by spβ-NGF compared to GnRH. STAR transcription was 3 folds higher at day 4 in females treated with spβ-NGF. In conclusion, the luteotrophic effect of spβ-NGF could be related to an increase of vascularization and up regulation of CYP11A1/P450scc and STAR transcripts enhancing progesterone secretion.

Abstract
BACKGROUND EuroFIT is a gender-sensitised, health and lifestyle program targeting physical activity, sedentary time and dietary behaviours in men. The delivery of the program in football clubs, led by the clubs' community coaches, is designed to both attract and engage men in lifestyle change through an interest in football or loyalty to the club they support. The EuroFIT program will be evaluated in a multicentre pragmatic randomised controlled trial (RCT), for which ~1000 overweight men, aged 30-65 years, will be recruited in 15 top professional football clubs in the Netherlands, Norway, Portugal and the UK. The process evaluation is designed to investigate how implementation within the RCT is achieved in the various football clubs and countries and the processes through which EuroFIT affects outcomes. METHODS This mixed methods evaluation is guided by the Medical Research Council (MRC) guidance for conducting process evaluations of complex interventions. Data will be collected in the intervention arm of the EuroFIT trial through: participant questionnaires (n = 500); attendance sheets and coach logs (n = 360); observations of sessions (n = 30); coach questionnaires (n = 30); usage logs from a novel device for self-monitoring physical activity and non-sedentary behaviour (SitFIT); an app-based game to promote social support for physical activity outside program sessions (MatchFIT); interviews with coaches (n = 15); football club representatives (n = 15); and focus groups with participants (n = 30). Written standard operating procedures are used to ensure quality and consistency in data collection and analysis across the participating countries. Data will be analysed thematically within datasets and overall synthesis of findings will address the processes through which the program is implemented in various countries and clubs and through which it affects outcomes, with careful attention to the context of the football club. DISCUSSION The process evaluation will provide a comprehensive account of what was necessary to implement the EuroFIT program in professional football clubs within a trial setting and how outcomes were affected by the program. This will allow us to re-appraise the program's conceptual base, optimise the program for post-trial implementation and roll out, and offer suggestions for the development and implementation of future initiatives to promote health and wellbeing through professional sports clubs.

Abstract
Embryonal tumors are a heterogeneous group of central nervous system (CNS) tumors whose subgroups have varying incidence and outcome. Despite these differences, they are often grouped as a single entity for study purposes. To date, there are no Canadian multi-institutional studies examining the incidence and outcome of all embryonal subtypes. The current study is an observational study reviewing embryonal tumors in all patients less than 36 months of age diagnosed with a CNS tumor in Canada from 1990 to 2005. Embryonal tumors accounted for 26.9% of all CNS tumors. Medulloblastomas were the highest proportion of the embryonal tumors at 61.5%. Atypical teratoid/rhabdoid tumors (AT/RT) had the second highest proportion of embryonal tumors at 18%. The proportion of primitive neuroectodermal tumors (PNET) was 16%, with 2.6 and 1.9% for congenital medulloepithelioma and ependymoblastoma tumors, respectively. AT/RT and PNET were more common in younger age groups. Medulloblastoma became more prevalent with increasing age, with its highest prevalence in the 25 to 36 month age group. Survival rates for our Canadian population at 18 and 24 months were 0.74 and 0.68 for medulloblastoma, 0.64 and 0.60 for PNET, and 0.36 and 0.29 for AT/RT, respectively. Overall, our data are comparable with published international rates for embryonal tumors. These incidence and outcome figures can guide future research into these rare tumors.

Abstract
IntroductionThe association between economic crises and mental health problems can be attributed to a number of factors. Among these, age seems to be an important determinant.ObjectivesThe aim of this study was to assess whether mental health of the Portuguese population following the onset of the 2008 recession, differs by age groups.MethodsA follow-up study (2015) on the population aged 18 to > 65 years old, using the National Mental Health Survey (n = 911). The age-group prevalence of mental health distress assessed by the ten-item Kessler's Psychological Distress Scale (K10) was calculated using Chi2 statistics and mental distress as a categorical variable (P < 0.05).ResultsMean mental distress score differed significantly according to age group, χ2(3) = 10.684, P < = 0.05. The results showed that the older groups (50–64 and 65 = years old) were more frequently under mental distress (17–19%) compared to younger people (18–49 = years old), which were less likely to report being distressed (8–12%).ConclusionsAge seems to be an important determinant of distress levels during the economic crisis in Portugal. Older adults reported to be more distressed compared to younger individuals. There are several hypotheses for a differential expression of psychological distress between age groups such as working status and retirement, which can express differential access to coping resources under such contextual negative pressure of economic recession. Further research on age groups is thus needed to better understand how recession generates adverse effects on mental well-being.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionDuring economic crises additional mental health risks emerge and social inequalities in health can widen. In order to ensure universal coverage of mental health care and to reduce the impact of the crisis, it is crucial to assess the needs of the population to be able to reorganize mental health care accordingly.ObjectivesTo analyse the use of services for mental health problems in Portugal during the economic crisis.MethodsIn this follow-up epidemiological study, a probability sub-sample of respondents to the 2008 national mental health survey (n = 911) was re-interviewed in 2015. Socio-demographic variables and treatment patterns were assessed using a structured interview, and psychological distress was measured using the Kessler-10 Scale. Descriptive analysis was conducted to characterize the use of services for mental health problems.ResultsIn total, 27.9% of the respondents sought treatment for mental health problems in the previous 5 years, and GPs were the most contacted professionals. Only 57.7% (n = 119) of the respondents with moderate or severe psychological distress (n = 197) reported recognizing they needed treatment. Among people with moderate or severe psychological distress who recognized their need for treatment, most received treatment (80.5%, n = 105), which was minimally adequate for 74.4% (n = 81). Low perceived need and structural barriers were the main obstacles for access to care.ConclusionsUnder-treatment, low continuity of care and low adequacy of treatment are problems that the Portuguese health system must address in order to meet the mental health challenges of the economic crisis.FundingEEA Grants: Programa Iniciativas em Saúde Pública.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
The association of antidepressant therapy with mania in people being treated for unipolar depression reinforces the importance of further clarification of this effect, since it has a huge implication in treatment approach and outcome. With this main objective, authors propose to make retrospective sociodemographic and clinical characterization of a group of patients with antidepressant induced mania in diagnosed unipolar depression, admitted in inpatient unit of Psychiatry and Mental Health Department of Centro Hospitalar de Trás-os-Montes e Alto Douro. Authors also aim to identify features that may increase the risk for mania or hypomania in people who present with an episode of depression, which can guide clinical orientation and improve outcome.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionPortugal is one of the European countries most affected by the Great Economic Recession. Mental health outcomes are likely to deteriorate during this period, with greater proportional impact among those more socially disadvantaged. Self-reported measures of financial difficulties and economic hardship are likely to be associated with psychological distress during this period.ObjectivesTo characterize the relationship between psychological distress and self-reported measures of financial difficulties and type of material deprivation during the Economic Recession in Portugal.MethodsA follow-up epidemiological survey was conducted in 2015, with a probability sub-sample of 911 respondents of the 2008 World Mental Health Survey Initiative Portugal. Psychological distress was evaluated by the Kessler-10 scale. Financial difficulties were assessed by asking the responds if they had enough money for their daily activities. Type of material deprivation considered difficulties in acquiring essential goods, paying debts or buying other goods (clothes or leisure activities). Chi-square analysis were used to evaluate the association between psychological distress, financial difficulties and type of material deprivation.ResultsA statistically significant association (P < 0.05) between psychological distress and financial difficulties was found. Among the respondents that reported not having enough money, 22% reported psychological distress. Regarding the type of material deprivation, a statistically significant association was only found for essential goods.ConclusionsDuring the economic crisis, financial difficulties and material deprivation in essential goods were associated with increased levels of psychological distress, potentially widening social and health inequalities across the Portuguese population.FundingEEA Grants, Programa Iniciativas em Saúde Pública.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Impaired cognitive function is a common complaint among oncologic patients. Chemotherapy-induced cognitive impairment (CICI), also called “chemobrain” or “chemofog” is currently recognized as a relatively common adverse effect of chemotherapeutic agents and is defined as the impairment of patients’ memory, learning, concentration, reasoning, executive function, attention, and visuospatial skills during and after discontinuation of chemotherapy. In particular, it is apparent that a subset of chemotherapy-treated haematological malignancy survivors experience cognitive impairment. On the other hand, the emotional distress associated with the disclosure of cancer diagnosis and/or the administration of chemotherapy represents a strong reason for psychosomatic manifestations in patients with cancer. The authors report a case of a patient with Hodgkin's lymphoma, cognitive impairment and symptoms of anxiety and they propose to discuss the controversies around the factors implicated on cognitive impairment in oncological patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Several studies have shown that ADHD has a significant negative impact on multiple domains of quality of life of children and adolescents, particularly in terms of behavioral, emotional and psychosocial quality of life. The psychopedagogical intervention can be therapeutic, preventive and promote educational inclusion. Moreover, it aims to address the learning process, how it is developed and how the individual relates himself to learning, both in the cognitive, social and emotional domains. Our purpose was to understand whether the psychopedagogical intervention influences the quality of life of adolescents with ADHD considering their pharmacological plans. The aim of this study was to evaluate the impact of a psychopedagogical intervention on quality of life of a sample of adolescents with ADHD taking into account their pharmacological plans (rubifen, ritalin, and concerta). We used quantitative and qualitative assessment measures: the KIDSCREEN-10, to measure the quality of life of these adolescents, and a semi-structured interview to assess the impact of a psychopedagogical intervention in the lives of these adolescents and their parents, respectively. The results showed that psychopedagogical intervention has a positive impact on the quality of life of adolescents with ADHD, as well as in the family dynamics. Due to the demands of school work (homework) and their negative impact on the family dynamics and consequently in the quality of life, the results corroborate the relevance of a psychopedagogical intervention to improve these areas. Thus, it appears that this type of intervention is very useful for adolescents with ADHD.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
O Brasil é responsável por cerca de 80% da produção de cocos na América do Sul. O resíduo de cascas de coco se transforma em um problema ambiental, uma vez que sua degradação pode ocorrer em até oito anos. Por outro lado, as fibras processadas podem se transformar em uma série de produtos utilizados na indústria da construção, automotiva e de insumo para agricultura ou jardinagem. O processamento da extração das fibras de coco verde ou seco é uma tarefa difícil exigindo trabalho árduo. A mecanização deste processo se faz necessária no sentido de melhorar a qualidade de vida do trabalhador deste segmento, facilitando o posterior aproveitamento das fibras e reduzindo o impacto ambiental do produto. Este estudo teve como objetivo desenvolver um equipamento triturador de cascas de coco. O princípio de funcionamento do triturador de coco foi baseado no acionamento de um rotor das facas, que efetua o processo de corte dos cocos, depositados no triturador. Visou-se obter um equipamento de utilização simples e prática, para que a trituração seja executada sem riscos. Foram executados ensaios de compressão para determinar a força de rompimento da fruta e também calculados os valores que deveriam ter o torque do motor a ser usado. O protótipo foi construído e testado. No teste, os cocos foram, em sua maioria, completamente triturados, indicando a eficiência da máquina.

Abstract
We report on a search for electronic recoil event rate modulation signatures in the XENON100 data accumulated over a period of 4 yr, from January 2010 to January 2014. A profile likelihood method, which incorporates the stability of the XENON100 detector and the known electronic recoil background model, is used to quantify the significance of periodicity in the time distribution of events. There is a weak modulation signature at a period of 431_{-14}^{+16} day in the low energy region of (2.0-5.8) keV in the single scatter event sample, with a global significance of 1.9σ; however, no other more significant modulation is observed. The significance of an annual modulation signature drops from 2.8σ, from a previous analysis of a subset of this data, to 1.8σ with all data combined. Single scatter events in the low energy region are thus used to exclude the DAMA/LIBRA annual modulation as being due to dark matter electron interactions via axial vector coupling at 5.7σ.

Abstract
A North American trial reported a significant reduction of lung cancer mortality and overall mortality as a result of annual screening using low-dose computed tomography (LDCT). European trials prospectively tested a variety of possible screening strategies. The main topics of current discussion regarding the optimal screening strategy are pre-test selection of the high-risk population, interval length of LDCT rounds, definition of positive finding, and post-test apportioning of lung cancer risk based on LDCT findings. Despite the current lack of statistical evidence regarding mortality reduction, the European independent diverse strategies offer a multi-perspective view on screening complexity, with remarkable indications for improvements in cost-effectiveness and harm-benefit balance. The UKLS trial reported the advantage of a comprehensive and simple risk model for selection of patients with 5% risk of lung cancer in 5 years. Subjective risk prediction by biological sampling is under investigation. The MILD trial reported equal efficiency for biennial and annual screening rounds, with a significant reduction in the total number of LDCT examinations. The NELSON trial introduced volumetric quantification of nodules at baseline and volume-doubling time (VDT) for assessment of progression. Post-test risk refinement based on LDCT findings (qualitative or quantitative) is under investigation. Smoking cessation remains the most appropriate strategy for mortality reduction, and it must therefore remain an integral component of any lung cancer screening programme.

Abstract
Abstract
Background
The aims of this prospective population-based cohort study were to identify the patient and hospital characteristics associated with emergency cholecystectomy, and the influences of these in determining variations between hospitals.
Methods
Data were collected for consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing the performance of emergency cholecystectomy were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2).
Results
Data were collected on 4744 cholecystectomies from 165 hospitals. Increasing age, lower ASA fitness grade, biliary colic, the need for further imaging (magnetic retrograde cholangiopancreatography), endoscopic interventions (endoscopic retrograde cholangiopancreatography) and admission to a non-biliary centre significantly reduced the likelihood of an emergency cholecystectomy being performed. The multilevel model was used to calculate the probability of receiving an emergency cholecystectomy for a woman aged 40 years or over with an ASA grade of I or II and a BMI of at least 25·0 kg/m2, who presented with acute cholecystitis with an ultrasound scan showing a thick-walled gallbladder and a normal common bile duct. The mean predicted probability of receiving an emergency cholecystectomy was 0·52 (95 per cent c.i. 0·45 to 0·57). The predicted probabilities ranged from 0·02 to 0·95 across the 165 hospitals, demonstrating significant variation between hospitals.
Conclusion
Patients with similar characteristics presenting to different hospitals with acute gallbladder pathology do not receive comparable care.

Abstract
OBJECTIVE To develop a model for prediction of term pre-eclampsia (PE) based on a combination of maternal factors and late third-trimester biomarkers. METHODS Data were derived from prospective screening for adverse obstetric outcomes in women attending their routine hospital visit at 35-37 weeks' gestation in two maternity hospitals in the UK. Uterine artery pulsatility index (UtA-PI) was measured in 5362 pregnancies, mean arterial pressure (MAP) in 5386 and serum placental growth factor (PlGF) and serum soluble fms-like tyrosine kinase-1 (sFlt-1) in 3920. Bayes' theorem was used to combine the a-priori risk of PE from maternal factors with various combinations of biomarkers, expressed as multiples of the median (MoM). Five-fold cross-validation was used to estimate the performance of screening for PE, requiring delivery at some stage after assessment. The empirical performance of screening was compared to model predictions. RESULTS In pregnancies that developed PE, the values of MAP, UtA-PI and sFlt-1 were increased and PlGF was decreased compared to unaffected pregnancies. For all biomarkers evaluated, the deviation from normal was inversely related to the gestational age at which delivery became necessary for maternal or fetal indications. Screening by maternal factors and by a combination of maternal factors with all biomarkers predicted 35% and 84% of PE, respectively, at a 10% false-positive rate. CONCLUSION A combination of maternal factors and biomarkers at 35-37 weeks' gestation can provide effective screening for term PE. Copyright © 2015 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
BACKGROUND/AIMS Essential fatty acids are important in maintaining skin function and their deficiency is associated with scali-ness and increased transepidermal water loss (TEWL). This can be one of the pathogenic processes implicated in atopic dermatitis (AD). Several studies have assessed the value of essential fatty acid-enriched diets in AD but the benefits of topical γ-lino-lenic acid (GLA) therapy have been less well evaluated. The aims of this study were: a) to compare the effects of GLA-con-taining emollients and classical emollients, regarding clinical benefits, cutaneous hydration (by a conductance method) and TEWL; b) to assess the clinical relevance of these two biomet-rical methods (conductance and TEWL). METHODS Twenty-three AD children were randomised into four groups, to compare three emollients containing GLA in different concentrations and one classical emollient. They were evaluated in eight visits for 12 weeks, using a clinical score and measurements of TEWL with the Tewameter™ and of cutaneous hydration with the Nova™. RESULTS Kruskal-Wallis statistical analysis showed significant differences in cutaneous hydration (P<0.05) between each of the three treatment groups and the control group. TEWL and clinical scores did not show statistically significant differences. During the study no children from the GLA groups developed eczematous lesions versus two children from the non-GLA group. CONCLUSIONS Discrepancies between conductance and TEWL measurements may represent false positive results of the former method due to electrical phenomena related to polarity of the GLA molecule or of other elements in the formulations. However, some differences in clinical evolution between the GLA and non-GLA groups require further studies to assess the possible additional benefits of topical emollients containing GLA.

Abstract
The involvement of transient receptor vanilloid type-1 (TRPV1) channels in pain modulation by the brain remains understudied. The rostroventromedial medulla (RVM) plays a key role in conveying to the spinal cord pain modulatory influences triggered in higher brain centres, with co-existence of inhibitory (antinociceptive) and facilitatory (pronociceptive) effects. In spite of some reports of TRPV1 expression in the RVM, it remains unknown if endovanilloid signalling plays a direct role in local pain modulation. Here we used a model of diabetic neuropathy, the streptozotocin (STZ)-diabetic rat, to study the role of endovanilloid signalling in RVM-mediated pain modulation during chronic pain. Four weeks after diabetes induction, the levels of TRPV1 mRNA and fatty acid amide hydrolase (FAAH), a crucial enzyme for endovanilloid catabolism, in the RVM of STZ-diabetic rats were higher than control. The RVM of STZ-diabetic rats presented decreased levels of several TRPV1 endogenous ligands, namely anandamide (AEA), palmitoylethanolamide (PEA) and oleoylethanolamide (OEA). Administration of capsaicin (a TRPV1 agonist) into the RVM decreased nociceptive behavioural responses in the inflammatory phase of the formalin test (phase 2). These findings suggest that diabetic neuropathy induces plastic changes of RVM endovanilloid signalling, indicating that TRPV1 may be a putative target for pain modulation in this chronic pain condition.

Abstract
IntroductionAn ongoing challenge for the behavioral health field in the United States is ensuring access to culturally and linguistically responsive treatments for the growing number of monolingual Spanish speakers. The limited availability of services further compromises mental health outcomes given the unique psychosocial stressors often experienced in this population, such as language barriers, family separation and inadequate social support, unemployment, trauma, and poverty.ObjectiveIn response to the local demand for services, the authors describe a specialized group program for monolingual Spanish speaking adults with chronic and persistent mental illness.AimsThe program aims are two-fold:– to reduce exacerbation of psychiatric symptoms for individuals presenting in an acute state of distress through the provision of recovery-oriented mental health services in a familiar setting and preferred language;– to offer a specialized behavioral health training experience for bilingual psychology doctoral students.MethodsThe group is led by the psychology fellow and is offered twice per week for a total of six hours, and includes elements of interpersonal and cognitive behavioral therapy; motivational interviewing; spirituality; coping skills training; and art/music.ResultsThe described mental health group program is the only one available in Spanish in the local community and has reduced utilization of the hospital emergency room. Consequently, it fills an important gap in the service system and offers care that would otherwise be unavailable for individuals in need.ConclusionsThe program is a cost-effective alternative to hospitalization for Spanish speaking Latinos and a unique professional experience for psychologists in-training interested in a career in the public sector.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
We evaluated single nucleotide polymorphisms (SNPs) associated with infection risk in children with newly diagnosed acute myeloid leukaemia (AML). We conducted a multicentre, prospective cohort study that included children aged ≤18 years with de novo AML. DNA was isolated from blood lymphocytes or buccal swabs, and candidate gene SNP analysis was conducted. Primary outcome was the occurrence of microbiologically documented sterile site infection during chemotherapy. Secondary outcomes were Gram-positive and -negative infections, viridans group streptococcal infection and proven/probable invasive fungal infection. Interpretation was guided by consistency in risk alleles and microbiologic agent with previous literature. Over the study period 254 children and adolescents with AML were enrolled. Overall, 190 (74.8%) had at least one sterile site microbiologically documented infection. Among the 172 with inferred European ancestry and DNA available, nine significant associations were observed; two were consistent with previous literature. Allele A at IL1B (rs16944) was associated with decreased microbiologically documented infection, and allele G at IL10 (rs1800896) was associated with increased risk of Gram-positive infection. We identified SNPs associated with infection risk in paediatric AML. Genotype may provide insight into mechanisms of infection risk that could be used for supportive-care novel treatments.

Abstract
The impact of nutrition on the performance of broiler breeders in terms of bodyweight profile, egg production, egg size and shell quality, mortality, fertility and hatchability has been well documented. However, studies on the direct effects of breeder nutrition on subsequent chick quality and offspring performance are limited. The present paper reviews the nutritional factors in broiler breeders that may improve chick quality and progeny performance. Recent research has suggested that the feeding of low crude protein and medium to high energy breeder diets in both rearing and laying period will not only have a positive impact on egg production, egg size, breeder fertility, hatchability and embryonic livability, but also on offspring performance. Improvements include better chick quality, higher chick weight, lower mortality, increased immune responses, enhanced litter quality and broiler growth. Breast-meat yield in the progeny can be improved as the energy to protein ratio increases from the rearing phase to the laying phase, indicating that nutrition of pullets can also affect growth and yields. The effects of maternal diet on offspring performance may depend on the sex of the progeny, with male broilers responding more than female broilers to breeders’ dietary protein and energy concentrations. However, little work has been conducted on the effects of individual amino acids in breeder diets on the subsequent generation. There seems to be some benefits with the use of long-chain poly-unsaturated fats in breeder diets on carcass quality of offspring, but these effects appear inconsistent at this stage. There is substantial evidence that confirms the direct effects of vitamin D and E, and trace minerals, especially in organic form, such as selenium, zinc and manganese, on chick quality and progeny performance. In fact, the impact of breeder nutrition on progeny performance in the field is more likely to be greater under conditions of poor breeder-flock uniformity, low vitamin and trace mineral contents or certain types of stress in the broiler house.

Abstract
This work demonstrates void-free cobalt filling of 56 μm tall, annular Through Silicon Vias (TSVs) using a mechanism that couples suppression breakdown and surface topography to achieve controlled bottom-up deposition. The chemistry, a Watts electrolyte containing a dilute suppressing additive, and processes are described. This work extends understanding and application of the additive-derived S-shaped Negative Differential Resistance (S-NDR) mechanism, including previous demonstrations of superconformal filling of TSVs with nickel, copper, zinc and gold.

Abstract
When wind speeds are 2-10 m s-1, reflective contrasts in the ocean surface make oil slicks visible to synthetic aperture radar (SAR) under all sky conditions. Neural network analysis of satellite SAR images quantified the magnitude and distribution of surface oil in the Gulf of Mexico from persistent, natural seeps and from the Deepwater Horizon (DWH) discharge. This analysis identified 914 natural oil seep zones across the entire Gulf of Mexico in pre-2010 data. Their ∼0.1 µm slicks covered an aggregated average of 775 km2. Assuming an average volume of 77.5 m3 over an 8-24 h lifespan per oil slick, the floating oil indicates a surface flux of 2.5-9.4 × 104 m3 yr-1. Oil from natural slicks was regionally concentrated: 68%, 25%, 7%, and <1% of the total was observed in the NW, SW, NE, and SE Gulf, respectively. This reflects differences in basin history and hydrocarbon generation. SAR images from 2010 showed that the 87 day DWH discharge produced a surface-oil footprint fundamentally different from background seepage, with an average ocean area of 11,200 km2 (SD 5028) and a volume of 22,600 m3 (SD 5411). Peak magnitudes of oil were detected during equivalent, ∼14 day intervals around 23 May and 18 June, when wind speeds remained <5 m s-1. Over this interval, aggregated volume of floating oil decreased by 21%; area covered increased by 49% (p < 0.1), potentially altering its ecological impact. The most likely causes were increased applications of dispersant and surface burning operations.

Abstract
BACKGROUND Most resectable pancreatic cancers are classified as T3, including those involving the porto-mesenteric vein. Survival and perioperative morbidity for venous resection have been found to be comparable to standard resection. We investigate factors associated with short and long term outcomes in pancreaticoduodenectomy with (PDVR) and without (PD) venous resection exclusively for T3 adenocarcinoma of the head of the pancreas. METHODS This is a UK multicenter retrospective cohort study assessing outcomes in patients undergoing PD and PDVR. All consecutive patients with T3 only adenocarcinoma of the head of the pancreas undergoing surgery between December 1998 and June 2011 were included. Multivariable logistic and proportional hazards regression analyses were performed to determine the association between the surgical groups and in-hospital mortality (IHM) and overall survival (OS). RESULTS 1070 patients were included of whom 840 (78.5%) had PD and 230 (21.5%) had PDVR. Factors independently associated with IHM were a high creatinine (aHR 1.14, p = 0.02), post-operative bleeding (aHR 2.86, p = 0.04) and a re-laparotomy (aHR 8.42, p = 0.0001). For OS, multivariable analyses identified R1 resection margin status (aHR 1.22, p = 0.01), N1 nodal status (aHR 1.92, p = 0.0001), perineural invasion (aHR 1.37, p = 0.002), tumour size >20mm (aHR 0.63, p = 0.0001) and a relaparotomy (aHR 1.84, p = 0.0001) to be independently associated with overall mortality. CONCLUSION This study on T3 adenocarcinoma of the head of the pancreas suggests that IHM is strongly associated with perioperative complications whilst OS is affected by histological parameters. Detailed pre-operative disease evaluation and advances in oncological treatment have the potential to improve OS.
