Bone Scan Index predicts outcome in patients with metastatic hormone-sensitive prostate cancer.

Objective: To evaluate the Bone Scan Index (BSI) for prediction of castration resistance and prostate cancer-specific survival (PCSS). In this retrospective study, we used novel computer-assisted software for automated detection/quantification of bone metastases by BSI. Patients with prostate cancer are M-staged by whole-body bone scintigraphy (WBS) and categorised as M0 or M1.

A genomic comparison of two termites with different social complexity.

The termites evolved eusociality and complex societies before the ants, but have been studied much less. The recent publication of the first two termite genomes provides a unique comparative opportunity, particularly because the sequenced termites represent opposite ends of the social complexity spectrum. Zootermopsis nevadensis has simple colonies with totipotent workers that can develop into all castes (dispersing reproductives, nest-inheriting replacement reproductives, and soldiers).

Stroke rehabilitation at home before and after discharge reduced disability and improved quality of life: a randomised controlled trial.

Objective: To evaluate if home-based rehabilitation of inpatients improved outcome compared to standard care.

Design: Interventional, randomised, safety/efficacy open-label trial.

Setting: University hospital stroke unit in collaboration with three municipalities.

Mesophilic versus thermophilic anaerobic digestion of cattle manure: methane productivity and microbial ecology.

In this study, productivity and physicochemical and microbiological (454 sequencing) parameters, as well as environmental criteria, were investigated in anaerobic reactors to contribute to the ongoing debate about the optimal temperature range for treating animal manure, and expand the general knowledge on the relation between microbiological and physicochemical process indicators. For this purpose, two reactor sizes were used (10 m(3) and 16 l), in which two temperature conditions (35°C and 50°C) were tested. In addition, the effect of the hydraulic retention time was evaluated (16 versus 20 days).

Tissue content of vitamin D3 and 25-hydroxy vitamin D3 in minipigs after cutaneous synthesis, supplementation and deprivation of vitamin D3.

Information regarding the endogenous storages of vitamin D3 after cutaneous vitamin D synthesis compared to oral vitamin D3 supplementation is sparse. Furthermore it is not known whether vitamin D3 can be stored for later use during periods of shortages of vitamin D3. To investigate the endogenous storages of vitamin D3 two studies were carried out in Göttingen minipigs.

Impact of chronic obstructive pulmonary disease on survival and symptoms of severe aortic valve stenosis.

Background: As patients with severe aortic valve stenosis (AS) develop symptoms their survival decreases rapidly, if treated conservatively. Transcatheter aortic valve implantation (TAVI) has been introduced as a less invasive treatment alternative, especially in inoperable patients, who often have severe comorbidities, including chronic obstructive pulmonary disease (COPD).

Materials And Methods: Since the beginning of our TAVI program in March 2008, data on all 131 TAVI patients were prospectively and consecutively collected in this registry with complete follow-up.

[Buschke-Ollendorff syndrome in two generations imitated Calvé-Legg-Perthes disease].

Buschke-Ollendorff syndrome is a rare condition characterized by skin manifestations and osteopoikilosis. We describe a mother and her son who presented with indurated skin lesions suggestive of connective tissue naevi. X-rays showed multiple symmetrical foci of osteosclerosis.

A cross-sectional study of stressors and coping mechanisms used by radiation therapists and oncology nurses: Resilience in Cancer Care Study.

Introduction: Occupational stress and burnout are well-recognised experiences reported by cancer care workers. The aim was to describe the frequency and severity of potential stressors as well as the effectiveness of coping skills of radiation therapists (RTs) and oncology nurses (ONs), which make up the two largest occupational groups in cancer care.

Methods: A questionnaire was distributed to RTs and ONs in two large tertiary hospitals in Queensland.

Resveratrol and inflammation: Challenges in translating pre-clinical findings to improved patient outcomes.

Throughout the Western world obesity prevalence is steadily increasing, and associated metabolic co-morbidities are projected to rise during the years to come. As weight loss and weight maintenance remains a major problem, new strategies to protect against obesity-related morbidity are needed. There is a clear association between obesity, low-grade inflammation and obesity-associated diseases, thus, the development of new anti-inflammatory substances is urgently needed as these may ultimately pave the way for novel treatments of obesity and lifestyle-related diseases.

Towards an integrated understanding of the consequences of fungus domestication on the fungus-growing termite gut microbiota.

Approximately 30 million years ago (MYA), the subfamily of higher termites Macrotermitinae domesticated a fungus, Termitomyces, as the main plant decomposer and food source for the termite host. The origin of fungiculture shifted the composition of the termite gut microbiota, and some of the functional implications of this shift have recently been established. I review reports on the composition of the Macrotermitinae gut microbiota, evidence for a subfamily core gut microbiota, and the first insight into functional complementarity between fungal and gut symbionts.

Plasma calprotectin and its association with cardiovascular disease manifestations, obesity and the metabolic syndrome in type 2 diabetes mellitus patients.

Background: Plasma calprotectin is a potential biomarker of cardiovascular disease (CVD), insulin resistance (IR), and obesity. We examined the relationship between plasma calprotectin concentrations, CVD manifestations and the metabolic syndrome (MetS) in patients with type 2 diabetes mellitus (T2DM) in order to evaluate plasma calprotectin as a risk assessor of CVD in diabetic patients without known CVD.

Methods: An automated immunoassay for determination of plasma calprotectin was developed based on a fecal Calprotectin ELIA, and a reference range was established from 120 healthy adults.

Electrical activity of the diaphragm during progressive cycling exercise in endurance-trained men.

The study aimed to investigate diaphragm respiratory drive modulation through electrical activity of the diaphragm (EADi) during progressive cycling in endurance-trained men (N=7) and to test day-to-day measurement reliability. Normalized EADi increased at exercise intensities from 40% workload (WL) to 70% and 85%WL but plateaued from 70% to 85% (p<0.05).

Convergent bacterial microbiotas in the fungal agricultural systems of insects.

Unlabelled: The ability to cultivate food is an innovation that has produced some of the most successful ecological strategies on the planet. Although most well recognized in humans, where agriculture represents a defining feature of civilization, species of ants, beetles, and termites have also independently evolved symbioses with fungi that they cultivate for food. Despite occurring across divergent insect and fungal lineages, the fungivorous niches of these insects are remarkably similar, indicating convergent evolution toward this successful ecological strategy.

Natalamycin A, an Ansamycin from a Termite-Associated sp.

We report a preliminary functional and complete structural characterization of a highly unusual geldanamycin analog, natalamycin A, that was isolated from strain M56 recovered from a South African nest of termites. Bioassay-guided fractionation based on antifungal activity led to the isolation of natalamycin A, and a combination of NMR spectroscopy and X-ray crystallographic analysis, including highly-accurate quantum-chemical NMR calculations on the largest and most conformationally-flexible system to date, revealed natalamycin A's three-dimensional solid- and solution-state structure. This structure along with the structures of related compounds isolated from the same source suggest a geldanamycin-like biosynthetic pathway with unusual post-PKS modifications.

Successful delivery after vaginal occlusion in addition to cerclage in a trachelectomy patient with recurrent second trimester pregnancy loss: a case report.

Pregnancy outcome after trachelectomy has high risk of complications such as second trimester pregnancy loss and preterm birth. We report beneficial effect of a simple procedure of vaginal occlusion in addition to cerclage in a patient with trachelectomy and two prior second trimester pregnancy losses.

[Inflammation as part of cerebral amyloid angiopathy disguised as a tumour].

A male with probable cerebral amyloid angiopathy (CAA)-related inflammation presented with headache and subacute hemi-paresis. After admission he developed a disturbance of consciousness and a CT brain scan showed oedema with significant midline shift. He was treated with corticosteroids with prompt clinical improvement.

Structure-activity relationship study of spider polyamine toxins as inhibitors of ionotropic glutamate receptors.

The spider polyamine toxins Joro spider toxin-3 (JSTX-3) and Nephila polyamine toxins-1 and -8 (NPTX-1 and NPTX-8) are isolated from the venom of the orb-weaver spider Nephila clavata (Joro spider). They share a high degree of structural resemblance, their aromatic head groups being the only difference, and were recently found to be very potent open-channel blockers of ionotropic glutamate (iGlu) receptors. In this study we designed and synthesized a collection of 24 analogues of these toxins using a recently developed solid-phase synthetic methodology.

Complementary symbiont contributions to plant decomposition in a fungus-farming termite.

Termites normally rely on gut symbionts to decompose organic matter but the Macrotermitinae domesticated Termitomyces fungi to produce their own food. This transition was accompanied by a shift in the composition of the gut microbiota, but the complementary roles of these bacteria in the symbiosis have remained enigmatic. We obtained high-quality annotated draft genomes of the termite Macrotermes natalensis, its Termitomyces symbiont, and gut metagenomes from workers, soldiers, and a queen.

Recovery experience and burnout in cancer workers in Queensland.

Purpose: Two key recovery experiences mediating the relationship between work demands and well-being are psychological detachment and relaxation over leisure time. The process of recovery from work-related stress plays an important role in maintaining well-being, but is poorly understood in cancer workers. The aim of this exploratory study was to examine the relationships of burnout, psychological well-being and work engagement with the recovery experiences of psychological detachment and relaxation in oncology staff.

Prostate cancer: a review of active surveillance.

The objective of this paper is to review the current recommendations for active surveillance in prostate cancer from the present prospective studies. Worldwide, there are increasing numbers of men with prostate cancer. It is now accepted as standard care that a number of men with favorable-risk disease can be followed with active surveillance.

Model study of the pressure build-up during subcutaneous injection.

In this study we estimate the subcutaneous tissue counter pressure during drug infusion from a series of injections of insulin in type 2 diabetic patients using a non-invasive method. We construct a model for the pressure evolution in subcutaneous tissue based on mass continuity and the flow laws of a porous medium. For equivalent injection forces we measure the change in the infusion rate between injections in air at atmospheric pressure and in tissue.

Plasma copeptin as marker of cardiovascular disease in asymptomatic type 2 diabetes patients.

Recently, copeptin was found associated with cardiovascular disease (CVD) and all-cause mortality in type 2 diabetes mellitus (T2DM) patients treated in primary care. This study aimed to evaluate whether plasma copeptin correlated to CVD in asymptomatic T2DM patients intensively investigated for sub-clinical CVD. A total of 302 T2DM patients referred to the Diabetes Clinic at Odense University Hospital, Denmark, entered the study.

The giraffe (Giraffa camelopardalis) rumen microbiome.

Recent studies have shown that wild ruminants are sources of previously undescribed microorganisms, knowledge of which can improve our understanding of the complex microbial interactions in the foregut. Here, we investigated the microbial community of seven wild-caught giraffes (Giraffa camelopardalis), three of which were fed natural browse and four were fed Boskos pellets, leafy alfalfa hay, and cut savanna browse, by characterizing the 16S rRNA gene diversity using 454 FLX high-throughput sequencing. The microbial community composition varied according to diet, but differed little between the ruminal fluid and solid fraction.

London's changing ethnic landscape, 2001-2011: a cartographic exploration.

London population became increasing more diverse ethnically over the decade 2001-2011, a period when the White population declined, with many commentators suggesting that there has been 'White flight' from some districts in the face of 'invasion' by members of ethnic minority groups. To examine how extensively the city's ethnic landscape changed during that period--and whether suggestions of the operation of 'invasion and succession processes' are valid--this article reports on statistical mapping of small area data for the two censuses. The results identify clearly-defined, substantial blocks of territory within the urban residential fabric where members of each of the main census respondent self-identified ethnic groups are concentrated.

Improving the risk assessment of lipophilic persistent environmental chemicals in breast milk.

Lipophilic persistent environmental chemicals (LPECs) have the potential to accumulate within a woman's body lipids over the course of many years prior to pregnancy, to partition into human milk, and to transfer to infants upon breastfeeding. As a result of this accumulation and partitioning, a breastfeeding infant's intake of these LPECs may be much greater than his/her mother's average daily exposure. Because the developmental period sets the stage for lifelong health, it is important to be able to accurately assess chemical exposures in early life.
