Association between digoxin use and gastrointestinal bleeding in contemporary continuous flow left ventricular assist device support.

BACKGROUND: Assess the association between digoxin use and gastrointestinal bleeding (GIB) in a multicenter continuous flow left ventricular assist device (LVAD) cohort. METHODS: Patients implanted with continuous flow LVADs with data on GIB and digoxin use from two centers were included in the analysis (n = 649). GIB events were captured up to 2 years of follow-up. Digoxin use was defined as digoxin prescribed at discharge or within the first 3 months after LVAD implantation. A negative binomial regression model was performed to determine the association between digoxin use and number of GIB events over the follow-up period. RESULTS: Mean age of the cohort was 57 years (±14) and 45% (293/649) were bridge to transplant (BTT). Digoxin was prescribed in 33% of patients. Digoxin use was associated with an unadjusted 32% reduction in the incidence of rate of all cause GIB (IRR 0.68, 95% CI 0.46-0.99, p = 0.049). After adjusting for age, sex, Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profile, renal function, and implanting center there was still a 34% reduction in the incidence rate (IRR 0.67, 95% CI 0.45-0.99, p = 0.048). When limiting the analysis to those with likely arteriovenous malformation associated GIB, the association strengthened (unadjusted: IRR 0.48, 95 % CI 0.26-0.89, p = 0.02, adjusted: IRR 0.47, 95 % CI 0.25-0.9, p = 0.022). CONCLUSIONS: In this multicenter study, inclusive of contemporary devices, digoxin use was associated with reduced GIB events. Prospective data will be required to confirm this association.

Development and characterization of 79 nuclear markers amplifying in viviparous and oviparous clades of the European common lizard.

The European common lizard (Zootoca vivipara) is a widely distributed species across Europe and Asia exhibiting two reproductive modes (oviparity/viviparity), six major lineages and several sublineages. It has been used to tackle a large variety of research questions, nevertheless, few nuclear DNA sequence markers have been developed for this species. Here we developed 79 new nuclear DNA sequence markers using a clonation protocol. These markers were amplified in several oviparous and viviparous specimens including samples of all extant clades, to test the amplification success and their diversity. 49.4% of the markers were polymorphic and of those, 51.3% amplified in all and 94.9% amplified in 5-7 of the extant Z. vivipara clades. These new markers will be very useful for the study of the population structure, population dynamics, and micro/macro evolution of Z. vivipara. Cross-species amplification in four lizard species (Psammodromus edwardsianus, Podarcis muralis, Lacerta bilineata, and Takydromus sexlineatus) was positive in several of the markers, and six makers amplified in all five species. The large genetic distance between P. edwardsianus and Z. vivipara further suggests that these markers may as well be employed in many other species.

Unprecedented simultaneous enhancement in damage tolerance and fatigue resistance of zirconia/Ta composites.

Dense (>98 th%) and homogeneous ceramic/metal composites were obtained by spark plasma sintering (SPS) using ZrO2 and lamellar metallic powders of tantalum or niobium (20 vol.%) as starting materials. The present study has demonstrated the unique and unpredicted simultaneous enhancement in toughness and strength with very high flaw tolerance of zirconia/Ta composites. In addition to their excellent static mechanical properties, these composites also have exceptional resistance to fatigue loading. It has been shown that the major contributions to toughening are the resulting crack bridging and plastic deformation of the metallic particles, together with crack deflection and interfacial debonding, which is compatible with the coexistence in the composite of both, strong and weak ceramic/metal interfaces, in agreement with predictions of ab-initio calculations. Therefore, these materials are promising candidates for designing damage tolerance components for aerospace industry, cutting and drilling tools, biomedical implants, among many others.

Phytotoxic and antimicrobial activity of volatile and semi-volatile organic compounds from the endophyte Hypoxylon anthochroum strain Blaci isolated from Bursera lancifolia (Burseraceae).

AIMS: To evaluate the phytotoxic, antifungal and antioomycete activity; and, determine the chemical composition of the volatile organic compounds (VOCs) and semi-volatile metabolites produced by the endophyte Hypoxylon anthochroum strain Blaci isolated from Bursera lancifolia. METHODS AND RESULTS: Based on its macro- and micro-morphological features, the strain Blaci was identified as Nodulisporium sp.; partial analysis of its ITS1-5.8-ITS2 ribosomal gene sequence revealed the identity of the teleomorphic stage of the fungus as H. anthochroum. Phytotoxic and antimicrobial activities of VOCs, and culture medium and mycelium organic extracts from H. anthochroum Blaci were determined by simple and multiple antagonism bioassays, and gas phase and agar dilution bioassays respectively. The volatile and semi-volatile metabolites were identified by gas chromatography-mass spectrometry. VOCs from a 5-day H. anthochroum strain Blaci culture caused the inhibition of seed germination, root elongation and seedling respiration on Amaranthus hypochondriacus, Panicum miliaceum, Trifolium pratense and Medicago sativa. In addition, extracts, phenylethyl alcohol and eucalyptol main compounds present in the VOCs and extract displayed a high phytotoxic activity, inhibiting the three physiological processes on the four test plants in a concentration-dependent manner. CONCLUSIONS: The results revealed that H. anthochroum strain Blaci produces a mixture of VOCs. These VOCs showed a strong phytotoxic activity on seed germination, root elongation, and seedling respiration of four plants and slightly affected the growth of phytopathogenic fungi and oomycetes. Also, the culture medium and mycelium extracts of H. anthochroum showed a high phytotoxic activity on the four test plants and, generally, the culture medium extract was more phytotoxic than the mycelium extracts. SIGNIFICANCE AND IMPACT OF THE STUDY: This work firstly reports the phytotoxic activity of volatile and semi-volatile compounds produced by the endophyte H. anthochroum strain Blaci on seed germination, root elongation, and seedling respiration of four different plants; consequently, these compounds could be useful in biocontrol of weeds and plant pathogens.

Tear proteome and protein network analyses reveal a novel pentamarker panel for tear film characterization in dry eye and meibomian gland dysfunction.

Dry eye and meibomian gland dysfunction are common ocular surface disorders. Discrimination of both conditions often may be difficult given the overlapping of signs and symptoms, and the lack of correlation with clinical parameters. A total of 144 individuals were included in this study. To search for proteome differences, tear proteins were collected by Merocel sponge and analyzed using 2D-PAGE. Comparative tear protein profile analysis indicated changes in the expression levels of fifteen proteins. Subsequent to MALDI-TOF/TOF protein identification, network analysis revealed expression/interaction connections with other proteins, thereby identifying additional putative markers. A screening validation assay demonstrated the discriminative power of six candidate biomarkers. A further validation study using multiplexed-like ELISA assays in tear samples collected with both sponge and capillary confirmed the high discriminatory power of five biomarkers: S100A6, annexin A1 (ANXA1), annexin A11 (ANXA11), cystatin-S (CST4), and phospholipase A2-activating protein (PLAA) with an area under ROC curve (AUC)≥ 97.9% (sensitivity ≥ 94.3%; specificity ≥ 97.6%) when comparing dry eye and control individuals. This panel also discriminated between dry eye, meibomian gland dysfunction and control individuals, with a global correct assignment (CA) of 73.2% between all groups. Correct assignment was not found to be significantly dependent on the tear collection method.

Clinical, functional and radiological results of Achilles tenorraphy surgically treated with mini-open technique.

AIM: The aim of this paper was to report clinical, functional and radiological results of 80 patients surgically treated with a combined mini-open and percutaneous surgical repair as proposed by Kakiuchi. METHODS: All patients were evaluated with a physical examination, evaluation scales, a functional test (Ergo-jump Bosco System), and an ultrasonographic exam along with Power Doppler Ultrasonography (PDU) (S/S). RESULTS: At a mean follow-up of 58 months no cases of rerupture were detected. VISA-A evaluation scale showed an excellent score in 63 patients (78.75%), a good score in 14 patients (17.5%), a fair score in two patients (2.5%), and a poor score in one patient (1.25%). Hannover scale showed an excellent score in 63 patients (78.75%), and a good score in 17 patients (21.25%). Ergo-Jump evaluation showed a 2.07% mean deficit of the affected limb at the Squatting Jump test, a 3.26% mean deficit at the Counter Movement Jump test, and a 0.0062% mean improvement at the Repetitive Jump test. Ultrasonographic exam showed in all cases a satisfactory recovery of the integrity of the operated tendon. The mean AP and LL widths showed a significant increase of 7.13±2.97 mm (+56.1%) and of 4.01±2.36 mm (+43.81%) respectively. According to the modified Öhberg score scale, PDU exam showed a grade +1 in 16 patients (20%) and a grade +2 in seven cases (8.7%). CONCLUSION: The absence of rerupture cases, the satisfactory functional and ultrasonographic results of the patients included in this study cause us to consider this technique as reliable and effective even in young high-demand patients.

DNA-PK promotes the survival of young neurons in the embryonic mouse retina.

Programmed cell death is a crucial process in neural development that affects mature neurons and glial cells, as well as proliferating precursors and recently born neurons at earlier stages. However, the regulation of the early phase of neural cell death and its function remain relatively poorly understood. In mouse models defective in homologous recombination or nonhomologous end-joining (NHEJ), which are both DNA double-strand break (DSB) repair pathways, there is massive cell death during neural development, even leading to embryonic lethality. These observations suggest that natural DSBs occur frequently in the developing nervous system. In this study, we have found that several components of DSB repair pathways are activated in the developing mouse retina at stages that coincide with the onset of neurogenesis. In short-term organotypic retinal cultures, we confirmed that the repair pathways can be modulated pharmacologically. Indeed, inhibiting the DNA-dependent protein kinase (DNA-PK) catalytic subunit, which is involved in NHEJ, with NU7026 increased caspase-dependent cell death and selectively reduced the neuron population. This observation concurs with an increase in the number of apoptotic neurons found after NU7026 treatment, as also observed in the embryonic scid mouse retina, a mutant that lacks DNA-PK catalytic subunit activity. Therefore, our results implicate the generation of DSB and DNA-PK-mediated repair in neurogenesis in the developing retina.

Capecitabine/cisplatin versus 5-fluorouracil/cisplatin as first-line therapy in patients with advanced gastric cancer: a randomised phase III noninferiority trial.

BACKGROUND: To compare capecitabine/cisplatin with 5-fluorouracil/cisplatin as first-line treatment for advanced gastric cancer (AGC). PATIENTS AND METHODS: In this randomised, open-label, phase III study, patients received cisplatin (80 mg/m(2) i.v. day 1) plus oral capecitabine (1000 mg/m(2) b.i.d., days 1-14) (XP) or 5-FU (800 mg/m(2)/day by continuous infusion, days 1-5) (FP) every 3 weeks. The primary end point was to confirm noninferiority of XP versus FP for progression-free survival (PFS). RESULTS: A total of 316 patients were randomised to XP (n = 160) or FP (n = 156). In the per-protocol population, median PFS for XP (n = 139) versus FP (n = 137) was 5.6 versus 5.0 months. The primary end point was met with an unadjusted hazard ratio (HR) of 0.81 [95% confidence interval (CI) 0.63-1.04, P < 0.001 versus noninferiority margin of 1.25]. Median overall survival was 10.5 versus 9.3 months for XP versus FP (unadjusted HR = 0.85, 95% CI 0.64-1.13, P = 0.008 versus noninferiority margin of 1.25). The most common treatment-related grade 3/4 adverse events in XP versus FP patients were as follows: neutropenia (16% versus 19%), vomiting (7% versus 8%), and stomatitis (2% versus 6%). CONCLUSIONS: XP showed significant noninferiority for PFS versus FP in the first-line treatment of AGC. XP can be considered an effective alternative to FP.

Fibrohistiocitoma maligno (fibroxantosarcoma) de cuero cabelludo: a propósito de un caso / Histiocytoma malignant fibrous (Fibroxantosarcoma) of scalp: a purpose of a case

Los tejidos blandos comprenden los músculos, tendones, la grasa, el tejido fibroso, el tejido sinovial, los vasos y los nervios. Alrededor del 60 por ciento de los sarcomas de tejidos blandos se originan en los miembros, siendo 3 veces más frecuentes en los miembros inferiores que en los superiores. En 30 por ciento de los casos se localiza en el tronco y en 40 por ciento son retroperitoneales. En el resto del 10 por ciento se trata de tumores de cabeza y cuello. La entidad denominada fibrohistiocitoma comprenden un gran número de tumores calcificados anteriormente como fibrosarcomas o como variedades polimorfas de otras sarcomas, y se caracteriza por una mezcla de células fusiformes (fibrosas) y células redondas (histiocitarias) dispuestas en un patrón estoriforme, junto con abundantes células gigantes y zonas de polimorfismo. La importancia de los estudios de inmunohistoquímica en los tumores de partes blandas radica en la necesidad que tiene el patólogo de precisar el diagnóstico histopatológico de lesiones benignas y malignas pseudosarcomatosas o sarcomatosas y poder diferenciarlas de neoplasias de otro origen. Se trata de paciente masculino de 65 años quien consulta por presentar desde agosto del 2006, caracterizado por lesiones ulcerosa en cuero cabelludo sangrantes quién se le tomo una primera biopsia que reporta.

Epitaxial growth of tungsten nanoparticles on alumina and spinel surfaces.

Isolated tungsten nanoparticles (α-W and ß-W phase) were synthesized and epitaxially grown on alumina and spinel particle surfaces with an average tungsten size of ≤20 nm for a low tungsten content (of ≤1.5 vol%). Using tungsten (VI) ethoxide alcoholic solutions, tungsten trioxide hydrated precursors were attached to a ceramic grains surface as a nanoparticle coating. High-resolution transmission electron microscopy (HRTEM) micrographs showed epitaxial interfaces between alumina, spinel and metallic tungsten. This epitaxial growth is assumed to be due to the effect of water vapour on the sublimation of ortho-tungstic acid during the reduction process in a hydrogen atmosphere. The planes involved in the epitaxy were found to be [Formula: see text] and [Formula: see text].
