Breast-feeding after transplantation.

Transplantation affords recipients the potential for a full life and, for some, parenthood. Female transplant recipients must continue to take immunosuppression during pregnancy and breast-feeding. This article reviews case and series reports regarding breast-feeding in those taking transplant medications.

The composition of arbuscular mycorrhizal fungal communities in the roots of a ruderal forb is not related to the forest fragmentation process.

Land-use changes and forest fragmentation have strong impact on biodiversity. However, little is known about the influence of new landscape configurations on arbuscular mycorrhizal fungal (AMF) community composition. We used 454 pyrosequencing to assess AMF diversity in plant roots from a fragmented forest.

Anthropogenic land use shapes the composition and phylogenetic structure of soil arbuscular mycorrhizal fungal communities.

Arbuscular mycorrhizal (AM) fungi play an important role in ecosystems, but little is known about how soil AM fungal community composition varies in relation to habitat type and land-use intensity. We molecularly characterized AM fungal communities in soil samples (n = 88) from structurally open (permanent grassland, intensive and sustainable agriculture) and forested habitats (primeval forest and spruce plantation). The habitats harboured significantly different AM fungal communities, and there was a broad difference in fungal community composition between forested and open habitats, the latter being characterized by higher average AM fungal richness.

Immunosuppressive drugs and fetal outcome.

Successful pregnancies have been reported in all types of solid-organ transplant recipients on a variety of immunosuppressive regimens. Immunosuppression is essential to maintain the transplanted organ and maternal health, thus the safety of these medications continues to be studied. This article reviews information in the literature and data from the National Transplantation Pregnancy Registry (NTPR) in the United States related to immunosuppressive medication and pregnancy.

Evaluation of a 4-protein serum biomarker panel-biglycan, annexin-A6, myeloperoxidase, and protein S100-A9 (B-AMP)-for the detection of esophageal adenocarcinoma.

Background: Esophageal adenocarcinoma (EAC) is associated with a dismal prognosis. The identification of cancer biomarkers can advance the possibility for early detection and better monitoring of tumor progression and/or response to therapy. The authors present results from the development of a serum-based, 4-protein (biglycan, myeloperoxidase, annexin-A6, and protein S100-A9) biomarker panel for EAC.

Transient neonatal liver disease after maternal antenatal intravenous Ig infusions in gestational alloimmune liver disease associated with neonatal haemochromatosis.

Objectives: Neonatal haemochromatosis is a rare gestational disease that results in severe foetal liver disease with extrahepatic iron overload, sparing the reticuloendothelial system. Recurrence can be prevented with intravenous immunoglobulin (IVIG) infusions during pregnancy, supporting an alloimmune aetiology. The aim of the study was to assess the effect of antenatal treatment with IVIG infusion on the outcome of pregnancies in women with a history of documented neonatal haemochromatosis likely owing to gestational alloimmune disease and to analyse IVIG tolerance.

Successful reversal of propionic acidaemia associated cardiomyopathy: evidence for low myocardial coenzyme Q10 status and secondary mitochondrial dysfunction as an underlying pathophysiological mechanism.

Dilated cardiomyopathy is a rare complication in propionic acidaemia (PA). Underlying pathophysiological mechanisms are poorly understood. We present a child of Pakistani consanguineous parents, diagnosed with late-onset PA at 18months of age.

A survey of the management of transient loss of consciousness in the emergency department.

Unlabelled: Transient loss of consciousness (TLoC) is a common presentation to the emergency department (ED). We sought to evaluate current practice in the management of patients with TLoC presenting to a large, city centre ED, against national standards.

Methods: The ED admissions database was searched to identify all patients attending with TLoC during October 2012.

GNAS is frequently mutated in both low-grade and high-grade disseminated appendiceal mucinous neoplasms but does not affect survival.

We analyzed a series of 55 disseminated appendiceal mucinous neoplasms treated at our institution for GNAS and KRAS mutations in an attempt to correlate mutation status with clinicopathological findings and patient survival. GNAS mutations (p.R201H, c.

An invasive vector of zoonotic disease sustained by anthropogenic resources: the raccoon dog in northern Europe.

The raccoon dog (Nyctereutes procyonoides) is an introduced species in Europe with a continually expanding range. Since the species is capable of affecting local ecosystems and is a vector for a number of severe zoonotic diseases, it is important to understand its food habits. Raccoon dog diet was studied in Estonia by examining the contents of 223 stomach samples collected during the coldest period of the year, August to March, in 2010-2012.

Revisiting the phylogeography and demography of European badgers (Meles meles) based on broad sampling, multiple markers and simulations.

Although the phylogeography of European mammals has been extensively investigated since the 1990s, many studies were limited in terms of sampling distribution, the number of molecular markers used and the analytical techniques employed, frequently leading to incomplete postglacial recolonisation scenarios. The broad-scale genetic structure of the European badger (Meles meles) is of interest as it may result from historic restriction to glacial refugia and/or recent anthropogenic impact. However, previous studies were based mostly on samples from western Europe, making it difficult to draw robust conclusions about the location of refugia, patterns of postglacial expansion and recent demography.

Tumor budding is associated with an increased risk of lymph node metastasis and poor prognosis in superficial esophageal adenocarcinoma.

The treatment approach for superficial (stage T1) esophageal adenocarcinoma critically depends on the pre-operative assessment of metastatic risk. Part of that assessment involves evaluation of the primary tumor for pathologic characteristics known to predict nodal metastasis: depth of invasion (intramucosal vs submucosal), angiolymphatic invasion, tumor grade, and tumor size. Tumor budding is a histologic pattern that is associated with poor prognosis in early-stage colorectal adenocarcinoma and a predictor of nodal metastasis in T1 colorectal adenocarcinoma.

Impacts of removing badgers on localised counts of hedgehogs.

Experimental evidence of the interactions among mammalian predators that eat or compete with one another is rare, due to the ethical and logistical challenges of managing wild populations in a controlled and replicated way. Here, we report on the opportunistic use of a replicated and controlled culling experiment (the Randomised Badger Culling Trial) to investigate the relationship between two sympatric predators: European badgers Meles meles and western European hedgehogs Erinaceus europaeus. In areas of preferred habitat (amenity grassland), counts of hedgehogs more than doubled over a 5-year period from the start of badger culling (from 0.

The renal circulation in normal pregnancy and preeclampsia: is there a place for relaxin?

During the first trimester of human pregnancy, the maternal systemic circulation undergoes remarkable vasodilation. The kidneys participate in this vasodilatory response resulting in marked increases in renal plasma flow (RPF) and glomerular filtration rate (GFR). Comparable circulatory adaptations are observed in conscious gravid rats.

Species richness of arbuscular mycorrhizal fungi: associations with grassland plant richness and biomass.

Although experiments show a positive association between vascular plant and arbuscular mycorrhizal fungal (AMF) species richness, evidence from natural ecosystems is scarce. Furthermore, there is little knowledge about how AMF richness varies with belowground plant richness and biomass. We examined relationships among AMF richness, above- and belowground plant richness, and plant root and shoot biomass in a native North American grassland.

Clinicopathologic and molecular analysis of disseminated appendiceal mucinous neoplasms: identification of factors predicting survival and proposed criteria for a three-tiered assessment of tumor grade.

Previous studies have demonstrated that the prognosis of disseminated mucinous appendiceal neoplasms is highly dependent upon tumor grade. Reflecting this, the 7th edition of the American Joint Committee on Cancer (AJCC) staging system now incorporates a three-tier grading system for prognostic staging of mucinous appendiceal tumors. However, the grading criteria are not well described.

Loss of SMAD4 protein expression is associated with high tumor grade and poor prognosis in disseminated appendiceal mucinous neoplasms.

The distinction between low-grade and high-grade disseminated appendiceal mucinous neoplasms is of critical importance in assessing prognosis and guiding patient therapy. SMAD4 encodes a protein that is a central component of the TGFβ signal transduction pathway, and loss of SMAD4 expression has been associated with poor prognosis in carcinomas of the gastrointestinal tract. We reviewed the clinicopathologic and molecular features of 109 disseminated appendiceal mucinous neoplasms identified over an 8-year period at our institution in an attempt to: (1) correlate SMAD4 immunohistochemical expression with tumor grade; and (2) assess the prognostic significance of SMAD4 expression in predicting overall survival.

Fifty thousand years of Arctic vegetation and megafaunal diet.

Although it is generally agreed that the Arctic flora is among the youngest and least diverse on Earth, the processes that shaped it are poorly understood. Here we present 50 thousand years (kyr) of Arctic vegetation history, derived from the first large-scale ancient DNA metabarcoding study of circumpolar plant diversity. For this interval we also explore nematode diversity as a proxy for modelling vegetation cover and soil quality, and diets of herbivorous megafaunal mammals, many of which became extinct around 10 kyr bp (before present).

Pneumococcus in Aboriginal and Torres Strait Islanders: the role of Aboriginal Health Workers and implications for nursing practice.

Abstract Background: Pneumonia is a common cause of hospitalization in Aboriginal and Torres Strait Islander men and women. Aim: This article seeks to describe the importance of immunizing against pneumonia in Aboriginal Australians and suggest strategies for screening and follow-up. Method: An integrative literature review, using both published and grey literature was undertaken to identify methods of screening and surveillance strategies for pneumococcus.

The degree of segmental aneuploidy measured by total copy number abnormalities predicts survival and recurrence in superficial gastroesophageal adenocarcinoma.

Background: Prognostic biomarkers are needed for superficial gastroesophageal adenocarcinoma (EAC) to predict clinical outcomes and select therapy. Although recurrent mutations have been characterized in EAC, little is known about their clinical and prognostic significance. Aneuploidy is predictive of clinical outcome in many malignancies but has not been evaluated in superficial EAC.

Prostate-specific antigen screening: a critical review of current research and guidelines.

Purpose: Screening for prostate cancer (adenocarcinoma of the prostate), using the prostate-specific antigen (PSA) test is controversial among health professionals and organizations who publish screening guideline recommendations for healthcare professionals. Controversy stems from conflicting research studies regarding the efficacy of PSA screening with regard to improved survival rates. This article serves as a critical review of the current guidelines and research to determine which screening practices may be most beneficial to utilize with patients.

Arbuscular mycorrhizal fungal networks vary throughout the growing season and between successional stages.

To date, few analyses of mutualistic networks have investigated successional or seasonal dynamics. Combining interaction data from multiple time points likely creates an inaccurate picture of the structure of networks (because these networks are aggregated across time), which may negatively influence their application in ecosystem assessments and conservation. Using a replicated bipartite mutualistic network of arbuscular mycorrhizal (AM) fungal-plant associations, detected using large sample numbers of plants and AM fungi identified through molecular techniques, we test whether the properties of the network are temporally dynamic either between different successional stages or within the growing season.

MUC2 expression is an adverse prognostic factor in superficial gastroesophageal adenocarcinomas.

Mucin core proteins (MUCs) are expressed in tissue-specific patterns in the gastrointestinal tract and expression is deregulated in Barrett's metaplasia. Based on differential expression, MUCs have been used to classify adenocarcinomas into distinct phenotypes (eg, intestinal, gastric, pancreaticobiliary, etc). Because MUC expression patterns carry prognostic significance in other tumors, we evaluated MUC expression in superficial adenocarcinomas of the gastroesophageal junction and esophagus (EAC) to determine whether there are differences in outcome associated with MUC subtype in this potentially curable subset of EAC.
