    Description: Seagrasses play an essential ecological role within coastal habitats and their worldwide population decline has been linked to different types of anthropogenic forces. We investigated, for the first time, the combined effects of future ocean warming and acidification on fundamental biological processes of Zostera noltii, including shoot density, leaf coloration, photophysiology (electron transport rate, ETR; maximum PSII quantum yield, Fv/Fm) and photosynthetic pigments. Shoot density was severely affected under warming conditions, with a concomitant increase in the frequency of brownish colored leaves (seagrass die-off). Warming was responsible for a significant decrease in ETR and Fv/Fm (particularly under control pH conditions), while promoting the highest ETR variability (among experimental treatments). Warming also elicited a significant increase in pheophytin and carotenoid levels, alongside an increase in carotenoid/chlorophyll ratio and De-Epoxidation State (DES). Acidification significantly affected photosynthetic pigments content (antheraxanthin, beta-carotene, violaxanthin and zeaxanthin), with a significant decrease being recorded under the warming scenario. No significant interaction between ocean acidification and warming was observed. Our findings suggest that future ocean warming will be a foremost determinant stressor influencing Z. noltii survival and physiological performance. Additionally, acidification conditions to occur in the future will be unable to counteract deleterious effects posed by ocean warming.

    Description / Table of Contents: Résumé L'échographie en temps réel a été employée au cours de 12 interventions pour abcès abdominaux, cette série comprenant des abcès du foie: 5, de la rate: 2, du pancréas: 2, de la région rétropéritonéale: 2, de la cavité péritonéale: 1. Le plus souvent, cette exploration préopératoire a été utile pour traiter les abcès. Elle a permis: 1) de localiser l'abcès avant toute dissection, 2) de porter le diagnostic lorsque l'abcès n'avait pas été reconnu avant l'intervention, 3) d'exclure la présence d'abcès qui avait été suspecté à tord avant ou au cours de l'intervention opératoire, 4) d'identifier les structures anatomiques adjacentes: vaisseaux sanguins, canaux biliaires et pancréatiques, intestin, 5) de guider l'aiguille de ponction à évacuer l'abcès. L'échotomographie opératoire constitue une méthode simple et dénuée de danger. Elle fournit au chirurgien une information précise qui permet de réduire le taux des drainages répétés et de réduire la mortalité des abcès de l'abdomen.
    Abstract: Abstracto Se empleo escanografía ultrasónica de tiempo real y de modo-B en el curso de 12 operaciones para abscesos abdominales. Estos incluyeron: 5 abscesos hepáticos, 2 esplénicos, 2 pancreáticos, 2 retroperitoneales y 1 intraperitoneal. En la mayoría de los casos se consideró que la ultrasonografía operatoria fue Útil en el manejo operatorio de los abscesos abdominales. El ultrasonido fue de valor en: 1) la localización de los abscesos antes de la disección de tejidos; 2) el establecimiento de un diagnóstico que no había sido hecho preoperatoriamente; 3) la exclusión de la presencia de abscesos que fueron sospechados en estudios preoperatorios o en el curso de una operacion exploratoria; 4) la identificatión de estructuras adyacentes tales como vasos sanguíneos, canales biliares y pancreáticos, e intestinos; y 5) guiar la aguja para la aspiración de abscesos. La ultrasonografía operatoria es una técnica segura y simple que provee al cirujano information precisa en el curso de la cirugía, la cual puede reducir la tasa de drenajes repetidos y la mortalidad de los abscesos abdominales.
    Notes: Abstract Real-time B-mode high resolution ultrasound scanning was employed during 12 operations for abdominal abscess. These included: 5 hepatic, 2 splenic, 2 pancreatic, 2 retroperitoneal, and 1 intraperitoneal abscesses. In most instances, operative ultrasonography was considered to be helpful in operative management of abdominal abscesses. Ultrasound was valuable in: (a) localizing abscesses before tissue dissection; (b) establishing the diagnosis which had not been made preoperatively; (c) excluding the presence of abscesses suspected on preoperative studies or at operative exploration; (d) identifying adjacent structures such as blood vessels, biliary and pancreatic ducts, and intestines; and (e) guiding the needle for aspiration of abscess. Operative ultrasonography is a safe and simple technique, providing the surgeon with accurate information during surgery which may reduce the re-drainage and mortality rates of abdominal abscess.

    Topics: Medicine
    Notes: Abstract The rodless, end-loop stoma was developed as an alternative to the more traditional loop stoma to minimize patient management problems. A retrospective review of our seven-year experience in 229 patients with end-loop colostomies (135), ileocolostomies (70), and ileostomies (24) is presented. A total of 30 stoma-related complications were observed in 27 stomas, for an overall complication rate of 13.1 percent. The most common complications were skin excoriation secondary to leakage (3.5 percent), retraction (3.5 percent), partial necrosis (2.6 percent), and peristomal sepsis (1.8 percent). Mucocutaneous separation, prolapse, and stenosis were each seen in less than one percent of patients. No cases of stomal herniation, obstruction, or hemorrhage were encountered. Twelve deaths occurred, but none was attributed to stoma-related complications. The rodless, endloop stoma is a simple and safe procedure with many advantages and a low incidence of complications.

    Topics: Medicine
    Notes: Abstract PURPOSE: Actinomyces israelii are normal inhabitants in the oral cavity and upper intestinal tract of humans. They rarely cause disease and are seldom reported as pathogens. As a pathogen it causes fistuli, sinuses, and may appear as an abdominal mass and/or abscess. The abdominal mass can masquerade as a malignant process that is very difficult to differentiate, often requiring surgical intervention with resection. Because of difficulty in making a preoperative diagnosis, we undertook this review to determine if all patients require surgical intervention and whether other adjunctive modalities may improve preoperative diagnosis. METHODS: We report two patients with abdominal actinomycosis, one affecting the sigmoid colon and the other the retroperitoneum, iliac crest region. Both simulated a malignant process and required operations for diagnosis and treatment. RESULTS: As reported, actinomycotic abdominal masses and strictures can be treated by penicillin alone. Long-term medical treatment seems to be very successful and avoids surgical resection. The difficulty is obtaining a definitive diagnosis. CONCLUSION: The computed tomographic scan is the most helpful diagnostic modality. Appearance of abdominal actinomycosis is usually a contrast enhancing multicystic lesion as was found in these two patients. Needle aspiration cytology can be fairly accurate in obtaining the diagnosis and is recommended for suspicious lesions.

    Description: In 2014, a DNA‐based phylogenetic study confirming the paraphyly of the grass subtribe Sporobolinae proposed the creation of a large monophyletic genus Sporobolus, including (among others) species previously included in the genera Spartina, Calamovilfa, and Sporobolus. Spartina species have contributed substantially (and continue contributing) to our knowledge in multiple disciplines, including ecology, evolutionary biology, molecular biology, biogeography, experimental ecology, biological invasions, environmental management, restoration ecology, history, economics, and sociology. There is no rationale so compelling to subsume the name Spartina as a subgenus that could rival the striking, global iconic history and use of the name Spartina for over 200 yr. We do not agree with the subjective arguments underlying the proposal to change Spartina to Sporobolus. We understand the importance of both the objective phylogenetic insights and of the subjective formalized nomenclature and hope that by opening this debate we will encourage positive feedback that will strengthen taxonomic decisions with an interdisciplinary perspective. We consider that the strongly distinct, monophyletic clade Spartina should simply and efficiently be treated as the genus Spartina.

    Climate Change Impacts on Seagrass Meadows and Macroalgal Forests: An Integrative Perspective on Acclimation and Adaptation Potential (2018)

    Description: Marine macrophytes are the foundation of algal forests and seagrass meadows-some of the most productive and diverse coastal marine ecosystems on the planet. These ecosystems provide nursery grounds and food for fish and invertebrates, coastline protection from erosion, carbon sequestration, and nutrient fixation. For marine macrophytes, temperature is generally the most important range limiting factor, and ocean warming is considered the most severe threat among global climate change factors. Ocean warming induced losses of dominant macrophytes along their equatorial range edges, as well as range extensions into polar regions, are predicted and already documented. While adaptive evolution based on genetic change is considered too slow to keep pace with the increasing rate of anthropogenic environmental changes, rapid adaptation may come about through a set of non-genetic mechanisms involving the functional composition of the associated microbiome, as well as epigenetic modification of the genome and its regulatory effect on gene expression and the activity of transposable elements. While research in terrestrial plants demonstrates that the integration of non-genetic mechanisms provide a more holistic picture of a species' evolutionary potential, research in marine systems is lagging behind. Here, we aim to review the potential of marine macrophytes to acclimatize and adapt to major climate change effects via intraspecific variation at the genetic, epigenetic, and microbiome levels. All three levels create phenotypic variation that may either enhance fitness within individuals (plasticity) or be subject to selection and ultimately, adaptation. We review three of the most important phenotypic variations in a climate change context, including physiological variation, variation in propagation success, and in herbivore resistance. Integrating different levels of plasticity, and adaptability into ecological models will allow to obtain a more holistic understanding of trait variation and a realistic assessment of the future performance and distribution of marine macrophytes. Such multi-disciplinary approach that integrates various levels of intraspecific variation, and their effect on phenotypic and physiological variation, is of crucial importance for the effective management and conservation of seagrasses and macroalgae under climate change.
