New species from Phytophthora Clade 6a: evidence for recent radiation.

During routine vegetation health surveys in the southwest of Western Australia (SWWA), several Phytophthora isolates with affinity to Clade 6a have been recovered. In this study, all known taxa from Clade 6a, P. inundata, P. humicola, P. gemini, P. 'walnut' and P. 'personii', and the new isolates were compared based on morphology and DNA sequence data from three nuclear genes and two mitochondrial genes resulting in the description of five new species, P. balyanboodja, P. condilina, P. cooljarloo, P. kwongonina and P. pseudorosacearum. With the exception of P. gemini and P. humicola, all species from Clade 6a have been recovered from natural ecosystems in SWWA. These species are morphologically similar, with predominantly ovoid sporangia and nested and extended internal proliferation. If oospores are present, they tend to be aplerotic with paragynous antheridia mostly attached adjacent to the oogonial stalk. They can all grow at 35 °C and have a fast growth rate on most agar media. These species have all been recovered from the rhizosphere soil and dead and dying plants within dry kwongon heathlands, often from water gaining sites and frequently from very isolated areas. The radiation, origin and potential ecological role of these species are discussed.

[Evolution of the carboxyhemoglobinemia and methemoglobinemia during endoscopic resection: An observational study]. / Évolution de la carboxyhémoglobinémie et de la méthémoglobinémie lors de résections endoscopiques : une étude observationnelle.

AIM OF THE STUDY: Combustion of organic tissues due to endoscopic resection could induce methemoglobin (MetHb) and carboxyhemoglobin (COHb) formation. The aim of this study is to evaluate MetHb and COHb formation in patients undergoing prostatic or bladder endoscopic procedures. METHODS: COHb and MetHb measurements were performed in 44 patients at the beginning and end of the procedure. A third measurement was done in patients who stayed more than one hour in the recovery room. Means were compared using Student t-test, simple regressions were used for quantitative variables and ANOVA for categorical variables. Multiple linear regressions were used for multivariate analysis. RESULTS: COHb increased by 0.5±0.9 % (95 % CI: 0.2 to 0.7 % P=0.001). MetHb increase was 0.0±0.4 % (95 % CI: -0.1 to 0.2 % P=0.552). In univariate analysis, the variables associated with COHb increase are the length of surgery, the amount of irrigation fluid and location (prostate or bladder) of the procedure. In the multivariate model, COHb increase is associated with the amount of liquid and the location. CONCLUSION: MetHb did not increase during endoscopic surgery. In contrast, COHb increases, and can, in some patients, exceed 2-4 %. This could be responsible for a decreased angina threshold in patients with ischemic heart disease. LEVEL OF EVIDENCE: 4.

Maternal obesity regulates gene expression in the hearts of offspring.

BACKGROUND AND AIMS: Growing evidence suggests maternal obesity leads to adverse outcomes for offspring, including increased cardiovascular disease (CVD). Alterations in taste preferences of offspring from mothers consuming a high fat diet (HFD) have also been reported. Given recent reports describing cardiac taste receptors, we examined whether the expression of umami and bitter taste receptors is modulated by maternal obesity, and compared this with the physiological challenge of maternal exercise. METHODS AND RESULTS: Female Sprague-Dawley rats were fed chow (C) or HFD (F) and half of each were provided with a running wheel to enable voluntary exercise (CE or FE), the others remaining sedentary (CS or FS). Two pups from each mother were killed at postnatal day 19. Both lean and obese dams undertook similar amounts of exercise (8.1 ± 2.4 vs 5.1 ± 1.5 km). Maternal obesity increased offspring body weight, adiposity, net and weight-corrected heart ventricle weight, with no effect of exercise. Maternal obesity also increased offspring plasma leptin concentrations, which were normalised by maternal exercise. Cardiac ventricle mRNA expression of bitter taste receptors, ß-adrenoceptor (Adrbk1) and angiotensin II receptor type 1a (Agtr1a) were significantly decreased in response to maternal obesity, with maternal exercise decreasing Agtr1a in FE offspring. No changes in umami receptors were observed. FTO mRNA expression was down-regulated by maternal HFD with an up-regulation in offspring of CE mothers. CONCLUSION: Maternal obesity affected the expression of bitter taste receptors and other genes in the heart ventricle, potentially implicating these genes in the development of CVD associated with maternal obesity.

A Conceptual Model to Describe the Decline of European Blackberry (Rubus anglocandicans), A Weed of National Significance in Australia.

Human activities have had an adverse impact on ecosystems on a global scale and have caused an unprecedented redispersal of organisms, with both plants and pathogens moving from their regions of origin to other parts of the world. Invasive plants are a potential threat to ecosystems globally, and their management costs tens of billions of dollars per annum. Rubus anglocandicans (European blackberry) is a serious invasive species in Australia. Herbicide and cultural control methods are generally inefficient or require multiple applications. Therefore, a biological control program using stem and leaf rust strains is the main option in Australia. However, biological control using rusts has been patchy, as host factors, climate, and weather can alter the impact of the rust at different locations. In 2007, Yeoh and Fontanini noticed that blackberry plants on the banks of the Donnelly and Warren rivers in the southwest of Western Australia were dying in areas that were being regularly monitored for the impact of rust as a biological control agent. The symptoms on blackberry became known as the disease "blackberry decline". Continuous and intensive investigations are required to discover the different biotic and abiotic components associated with specific declines in plant populations. The only agent so far introduced to Australia for the biological control of blackberry is the rust Phragmidium violaceum.

[Pharmaconutrition with parenteral selenium in sepsis]. / Farmaconutrición parenteral con selenio en la sepsis.

Critical illness is characterized by oxidative stress which leads to multiple organ failure, and sepsis-related organ dysfunction remains the most common cause of death in the intensive care unit. Over the last 2 decades, different antioxidant therapies have been developed to improve outcomes in septic patients. According to recent evidence, selenium therapy should be considered the cornerstone of the antioxidant strategies. Selenium given as selenious acid or sodium selenite should be considered as a drug or pharmaconutrient with prooxidant and cytotoxic effects when a loading dose in intravenous bolus form is administered, particularly in the early stage of severe sepsis/septic shock. To date, several phase ii trials have demonstrated that selenium therapy may be able to decrease mortality, improve organ dysfunction and reduce infections in critically ill septic patients. The effect of selenium therapy in sepsis syndrome must be confirmed by large, well designed phase iii clinical trials.

Deep and stable interferometric nulling of broadband light with implications for observing planets around nearby stars

The number of indirectly detected planetary systems around nearby stars has grown tremendously since their initial discovery five years ago. But the direct observation of light reflected from these systems remains a formidable task, because of the high contrast ratios between them and their parent stars, and because of the tiny angular separations. Theoretically, these difficulties can be overcome by using a dual-aperture stellar interferometer in which the starlight is cancelled, or 'nulled' by broadband destructive interference, leaving the planet's light visible. Although the basic requirement of equal and oppositely directed electric fields is easy to state, an experimental demonstration of deep broadband nulling has been lacking, owing to difficulties engendered by the needs for extreme symmetry and stability, and low dispersion in the optical system. Here we report the deep (10(-4)) and stable nulling of broadband (18% bandwidth) thermal light. These results validate the physical principles underlying future planet-searching interferometers, and our laboratory instrument will serve as a prototype for the nulling instrument to be implemented on the Keck interferometer in 2001.

[Acquired angioedema due to C1-inhibitor deficiency: CREAK recommendations for diagnosis and treatment]. / Angiœdèmes par déficit acquis en C1-inhibiteur : recommandations du CREAK pour le diagnostic et la prise en charge.

Acquired angioedema with C1-inhibitor deficiency is a rare and peculiar entity belonging to the spectrum of bradykinin angioedemas. It usually occurs in subjects over 60 years old, and is mostly associated with a B-cell lymphoid hemopathy or a monoclonal gammopathy. The diagnosis relies on at least one angioedema episode, lasting more than 24 h, and on the decrease of functional C1-inhibitor. Low C1q is observed in 90% of patients, and an anti C1-inhibitor antibody is found in 50% of patients. The treatment of severe attacks relies on icatibant or C1-inhibitor perfusions. Long term prophylaxis in patients with frequent attacks requires treatment of the associated hemopathy if so. In case of idiopathic angioedema, tranexamic acid and danazol may be used, provided that there is-no thrombophilia; as well as rituximab as second-line treatment. Inhibitors of kallikrein still need to be evaluated in this therapeutic indication.

Plant growth promotion and biological control of Pythium aphanidermatum, a pathogen of cucumber, by endophytic actinomycetes.

AIMS: To evaluate the potential of Actinoplanes campanulatus, Micromonospora chalcea and Streptomyces spiralis endophytic in cucumber roots, to promote plant growth and to protect seedlings and mature plants of cucumber from diseases caused by Pythium aphanidermatum, under greenhouse conditions. METHODS AND RESULTS: Three endophytic isolates, out of 29, were selected through tests aimed at understanding their mechanisms of action as biocontrol agents and plant growth promoters. When applied individually or in combination, they significantly promoted plant growth and reduced damping-off and crown and root rot of cucumber. The combination of the three isolates resulted in significantly better suppression of diseases and plant growth promotion, than where the plants were exposed to individual strains. CONCLUSIONS: The three selected actinomycete isolates colonized cucumber roots endophytically for 8 weeks, promoted plant growth and suppressed pathogenic activities of P. aphanidermatum on seedling and mature cucumber plants. SIGNIFICANCE AND IMPACT OF THE STUDY: The results clearly show that the endophytic, glucanase-producing actinomycetes used, especially as a combined treatment, could replace metalaxyl, which is the currently recommended fungicide for Pythium diseases in the United Arab Emirates. These endophytic isolates also have the potential to perform as plant growth promoters, which is a useful attribute for crop production in nutrient impoverished soils.

[Selenium supplementation in critically ill patients: pharmacological issues and current evidence]. / Suplementación con selenio en el paciente crítico: aspectos farmacológicos y evidencia actual.

High dose intravenous selenium may be associated with a significant reduction in mortality among critically ill patients with systemic inflammation. Currently, parenteral selenium as sodium selenite seems to be a cornerstone of the antioxidant defence in the critically ill. So far, several clinical trials have evaluated the effects of selenium in monotherapy or as part of a multi-micronutrient approach, on relevant clinical end points for critically ill patients. Nonetheless, the results from these studies have sometimes been contradictory. We now have a better understanding of the pharmacokinetics of the initial and transient pro-oxidant effect of an intravenous bolus followed by the antioxidant effect of continuous infusion, which seems efficacious and safe among critically ill patients. Clinical confirmation of the potentially advantageous synergism between selenium and glutamine may soon be forthcoming but the most appropriate and the optimum time of supplementation remains undetermined. Short-term intravenous selenite (bolus injection plus continuous infusion) has shown to be safe and capable of optimizing serum selenium and antioxidant selenoenzymes activities. However, additional dose-ranging trials are necessary to elucidate an optimal and safe posology with confirmed pharmacokinetic profiles before more definitive phase III trials can be conducted.

A review and critical appraisal of measures of therapist-patient interactions in mental health settings.

OBJECTIVES: To assemble and to appraise critically the current literature on tests and measures of therapist-patient interactions in order to make recommendations for practice, training and research, and to establish benchmarks for standardisation, acceptability and routine use of such measures. DATA SOURCES: Major electronic databases (including PsycINFO) were searched from inception to 2002. REVIEW METHODS: A comprehensive conceptual map of the subject area of therapist-patient interactions was developed through data extraction from, and analysis of, studies selected from the literature searches. The results of these searches were assessed and appraised to produce a set of possible therapist-patient measures. These measures were then evaluated. RESULTS: The contextual map included the various concepts and domains that had been used in the context of the literature on therapist-patient interactions, and was used to guide the successive stages of the review. Three developmental processes were identified as necessary for the provision of an effective therapeutic relationship: 'establishing a relationship', 'developing a relationship' and 'maintaining a relationship'. Eighty-three therapist-patient measures having basic information on reliability and validity were identified for critical appraisal. The areas of the conceptual map that received most coverage (i.e. over 50% measures associated with them) were framework, therapist and patient engagement, roles, therapeutic techniques and threats to the relationship. These areas relate to the three key developmental processes outlined above. Of the 83 measures matching the content domain, 43 met the minimum standard. A total of 30 measures displayed adequate responsiveness or precision. None of the 43 measures that met the minimum standard was fully addressed in terms of acceptability and feasibility evidence. The majority of these measures had three or fewer components described. Therefore, out of a total of 83 measures matching the content domain, no measure could be said to have met an industry standard. CONCLUSIONS: The findings indicate that the therapist-patient interaction can be measured using a wide range of instruments of varying value. However, due care should be taken in ensuring that the measure is suitable for the context in which it is to be used. Following on from this work, it is suggested that specific research networks for the development of therapist-patient measures should be established, that research activity should prioritise investment in increasing the evidence base of existing measures rather than attempting to develop new ones, and that research activity should focus on improving these existing measures in terms of acceptability and feasibility issues.

What informs and shapes ethical practice in intellectual disability services?

BACKGROUND: Theoretical literature in the intellectual disability (ID) field identified a mismatch between professional codes of practice (which assume clients to be 'autonomous') and the reality of fostering autonomy for people with ID (who at times are completely dependent on others). This research aimed to understand how professionals bridged this disjunction and actually provided ethical services with this client group. METHOD: Nine professionals from adult ID services who had consulted with local Ethical Advisory Groups were interviewed about their experience of addressing an ethical issue within their work. Accounts were subjected to narrative analysis. RESULTS: Professionals' narratives featured the following themes: differing sources of conflict, professional vulnerability and seeking validation around resolution, centrality of relationships, fragility of resolutions and maintaining moral integrity. CONCLUSIONS: Findings revealed systemic pressure on professionals to find 'definitive' solutions to ethical dilemmas when the issues were not open to such resolution. Findings were reviewed in light of ethical literature that shows how professionals' work inevitably features close and enduring relationships with people with ID. We suggest professionals need to draw on ethical frameworks that can accommodate relational aspects of their practice.

A preliminary study of a measure of role-play competence in psychodynamic interpersonal therapy.

We report a 15-item role-play competence measure. Ratings by three judges of 34 role plays from psychodynamic interpersonal therapy training showed good inter-rater (.73-.79) and internal reliability (.84-.96). Validity was supported as scores were statistically significantly associated with psychotherapy experience. Most participants achieved satisfactory ratings supporting the training.

E-therapies in England for stress, anxiety or depression: what is being used in the NHS? A survey of mental health services.

OBJECTIVE: To document the range of web and smartphone apps used and recommended for stress, anxiety or depression by the National Health Service (NHS) in England. DESIGN: The study was conducted using Freedom of Information (FOI) requests and systematic website searches. DATA SOURCES: Data were collected via FOI requests to NHS services between 13 February 2015 and 31 March 2015, and searches conducted on NHS apps library websites between 26 March 2015 and 2 November 2015. DATA COLLECTION/EXTRACTION METHODS: Data were compiled from responses to: (1) FOI requests sent to all Improving Access to Psychological Therapies (IAPT) services and NHS Mental Health Trusts in England and (2) NHS apps library search results. RESULTS: A total of 61 (54.95%) out of the then 111 IAPT service providers responded, accounting for 191 IAPT services, and all 51 of the then NHS Mental Health Trusts responded. The results were that 13 different web apps and 35 different smartphone apps for depression, anxiety or stress were available through either referral services or the online NHS Apps Libraries. The apps used and recommended vary by area and by point of access (online library/IAPT/trust). CONCLUSIONS: Future research is required to establish the evidence base for the apps that are being used in the NHS in England. There is a need for service provision to be based on evidence and established guidelines.
