ObjectiveTonsillectomy is still one of the most common surgical procedures, but there exists no standard guideline for pain management after tonsillectomy. Our aim is to determine whether oral spray of flurbiprofen reduces pain and has an influence on other morbid outcomes following tonsillectomy.Study DesignProspective, double‐blind, randomized, placebo controlled.SettingPatients at Ataturk Training and Research Hospital, Ankara, Turkey.Subjects and MethodsThis study was performed on 84 patients (45 in flurbiprofen group, 39 in placebo group) who underwent tonsillectomy. The patients were randomly chosen, and each used oral spray of flurbiprofen 3 times daily or placebo solution at the same regimen. Efficacy was assessed by changes in Numeric Pain Rating Scale. Data were collected at postoperative days 1, 3, 5, and 7 for pain, bleeding, and healing. Data for Mallampati scores were also collected.ResultsThere were no significant difference between groups with respect to the demographic data. The flurbiprofen group had statistically significant lower pain scores at days 1, 3, 5, and 7 (P =. 000, P =. 002, P =. 001, P =. 000, respectively). On days 3 and 7, pain scores were significantly different between different Mallampati groups (P =. 049, P =. 015, respectively). The flurbiprofen group required less analgesic than the placebo group during the study period on days 1, 3, 5, and 7 (P =. 001, P =. 001, P =. 03, P =. 001, respectively). Healing and side effects were not significantly different between the groups.ConclusionIn this study, topical use of flurbiprofen may reduce posttonsillectomy pain without any evidence of additional complications.

Objective: To evaluate the effect of course length and corridor width on 2-minute walk test results in older adults. Design: Cross-sectional and experimental study with different test conditions. Setting: Geriatric rehabilitation clinic. Subjects: A total of 21 patients (median age 81 years). Main measures: Patients walked two minutes on a 20 m and 40 m course with a 2 m or 1 m corridor width and on a continuous course without any turning in a corridor of 2 m width, five walks in total. The distance traveled within the 2 minutes was recorded. Results: Compared with the 20 m course length, median walking distances measured by the 2-minute walk test in a walk way 2 m broad were better on the continuous corridor without any turn (136.9 m vs. 129.3 m, p = 0.002) and on the 40 m course (131.8 m vs. 129.3 m, p = 0.003). Walking distance on a 20 m course length was longer in a corridor of 2 m width compared with the 1 m corridor width (129.3 m vs. 119.2 m, p = 0.005). The walking distance was not affected by corridor width on the 40 m course length. Conclusions: Performance of elderly patients on the 2-minute walk test is influenced by the width of the corridor and the length of the course used.

Background: Hospitalizations in patients with metastatic cancer occur commonly at the end of life but have not been well-described in individuals with metastatic breast cancer. Aim: To describe the reasons for admission and frequency of palliative care and hospice utilization in hospitalized patients with metastatic breast cancer. Design: This was a retrospective chart review of patients who had their first hospitalization with a diagnosis of metastatic breast cancer between 1 January 2009 and 31 December 2010. To standardize follow-up time, we collected data for 3 years post the index hospitalization. Setting/participants: We identified 123 consecutive patients who were hospitalized for the first time with a diagnosis of metastatic breast cancer at a single, tertiary care center. Results: Uncontrolled symptoms accounted for half (50%, 62/123) of index admissions. The majority of patients died during the follow-up period (76%, 94/123), and the median time from index admission to death was 6 months (range: 0–34 months). Approximately half (53%, 50/94) died in the hospital or within 14 days of last hospital discharge, and less than one-third (29%, 27/94) were referred to hospice after their last hospitalization. The inpatient palliative care team evaluated 57% (54/94) of those who died at least once during an admission, but only 17% (16/94) of patients attended an outpatient palliative care appointment. Conclusions: Hospitalized patients with metastatic breast cancer are commonly admitted for uncontrolled symptoms and have a poor prognosis. However, only a minority receive outpatient palliative care or are referred to hospice during their last hospitalization prior to death.

Objective The risk of thrombosis is increased in patients with systemic lupus erythematosus (SLE). Few studies have assessed factors associated with thrombosis within the pediatric SLE (pSLE) population. We sought to better characterize these associated factors in pSLE patients using the Childhood Arthritis & Rheumatology Research Alliance (CARRA) registry. Methods Within the CARRA registry, patients with a history of thrombosis were compared to those without. Univariate logistic regression was used to calculate odds ratios. A multivariable logistic regression model was conducted that included variables from the univariate analysis that had a p value < 0.10 and other variables identified as clinically significant from published literature. Results Among the 979 pSLE patients in the CARRA registry, 24 (2.5%) patients had a history of arterial thrombosis and 35 (3.6%) of venous thrombosis. In the univariate analysis, the odds ratio of having a thrombotic event were found to be significantly higher in patients with a history of vasculitis, avascular necrosis (AVN), or antiphospholipid antibody (aPL). Similar results were found for vasculitis, AVN, and aPL in the multivariable analysis. Conclusion Our study of pSLE patients suggests that vasculitis, positive APL, and AVN are associated with thrombotic events in this population.

Objective: We report two cases of patients with relapsing-remitting multiple sclerosis with early-onset thrombocytopenia and autoimmune thyroid disease after the first treatment course with 60-mg alemtuzumab. Methods: Case series and review of the literature. Results: Both patients showed severe thrombocytopenia with platelet counts of 2 × 109 and 11 × 109/L, respectively, as well as increased thyroid antibodies within only a few months after initiating alemtuzumab treatment (11 and 9 months). Both patients responded considerably well to medical therapy including corticosteroids and intravenous immunoglobulins with slow platelet recovery over several weeks. Interestingly, both patients were previously treated with fingolimod and showed a marked lymphocytopenia that led to discontinuation. Conclusion: These cases emphasize the necessity of careful clinical surveillance and proper education of patients treated with alemtuzumab as proposed by the safety-monitoring program. Previous severe lymphocytopenia under therapy with other disease-modifying therapies may be a risk factor for the development of immune thrombocytopenia.

Introduction: The aim of this study was to assess whether individual patients’ or bypass characteristics may influence long-term results of prosthetic above-knee femoropopliteal bypasses in patients with claudication in today’s endovascular era. Methods: Seventy-one consecutivee Expanded Polytetrafluoroethylene (e-PTFE) bypasses were considered. All patients presented a debilitating claudication. Patency of grafts was achieved by Kaplan-Meier method. The association between individual patients’ or graft characteristics and primary patency (PP) or secondary patency (SP) was assessed via Cox regression models. Results: An immediate technical success was achieved in all cases. No patient was lost during follow-up (8-90 months, median = 34 months). The median PP was 48 months. Occlusion occurred in 32 bypasses (45%). Eight (25%) of these were treated conservatively. Fifty-two bypasses (73%) were still patent at the end of follow-up, and 13 (25%) of these had been submitted to one or more surgical revisions. There were 2 graft infections. Of 17 (25%) patients with occluded graft at the end of follow-up, 2 (2.8%) had significant aggravation followed by limb loss. The PP was directly influenced by undetected minor distal anastomosis technical defects (hazard ratio [HR] = 5.89, P value = .000002), popliteal artery size (HR = 0.62, P value = 0.007), and distal anastomosis angle ≥40° (HR = 5.55, P value = .003). The SP was associated strictly to technical defects (HR = 11.08, P value = .000007). Multivariable analyses confirmed the influence of technical defects (HR = 6.42, P value = .000003) and anastomosis angle (HR = 1.05, P value = .009) on PP and that of technical defects on SP (HR = 10.84, P value = .00003). A significantly shorter SP was also observed after a previous failed endovascular treatment on the superficial femoral artery (HR = 3.73, P value = .02). Conclusion: An adequate arterial size, an ideal anastomotic angle, and the absence of minor, technical defects have a major role in prosthetic above-knee femoropopliteal bypass long-term outcome. A previous, failed endovascular procedure on the superficial femoral artery could markedly alter the natural history of patients with claudication because this approach seems to have a detrimental effect on long-term outcome of grafts needing surgical revisions

Published: March 2016

In Crohn’s disease (CD), the tissue-damaging inflammation is sustained by defects of counter-regulatory mechanisms, which normally inhibit immune-inflammatory signals and promote repair of mucosal injury. In particular, in inflamed gut of CD patients there are elevated levels of Smad7, an intracellular protein that inhibits the function of transforming growth factor (TGF)-β1. Knockdown of Smad7 with a specific antisense oligonucleotide, named mongersen, restores TGF-β1 activity thus leading to suppression of inflammatory pathways and resolution of colitis in mice. Consistently, oral administration of mongersen to patients with active CD induces clinical remission. In this article, we review the available data supporting the pathogenic role of Smad7 in CD and discuss the results of recent phase I and II trials assessing the efficacy and safety of mongersen in CD patients.
Reconstruction of an Ordovician seafloor volcanohydrothermal system: a case study from the Copper Coast, southeastern Ireland using field, geochemical and fluid inclusion data

Published: March 2016

AbstractVolcanic rocks in south County Waterford include flow-top hyaloclastite, pillow lavas and peperite, which are formed typically by sub-aqueous eruption or intrusion into unconsolidated sediment. Element mobility in wet sediment during emplacement of volcanic intrusions was reconstructed on a variety of spatial scales using bulk-rock and mineral analysis. Magma-sediment and magma-water interactions enhanced hydrothermal alteration. The chemistry of chlorite was a function of mixing between an Fe-rich magmatic fluid and a Mg-rich meteoric fluid. Chlorite geothermometry yields temperatures of formation between 230 and 388°C compatible with other metamorphic indicators. Fluid inclusion microthermometric data from genetically-related mineralized quartz veins reveal a hydrothermal vein mineralization event that occurred at lower temperatures during the end stage of volcanic activity. A convection driven mixing trend reflects the trapping of co-existing brine with entrained seawater concomitant with, the late stages of emplacement of the Bunmahon Volcano intrusions.

AbstractThe new mineral species ferrostalderite, CuFe2TlAs2S6, was discovered in the Lengenbach quarry, Binn Valley, Wallis, Switzerland. It occurs as minute, metallic, black, equant to prismatic crystals, up to 50 mu;m, associated with dolomite, realgar, baumhauerite (?) and pyrite. Minimum and maximum reflectance data for COM wavelengths in air are [λ (nm): R (%)]: 471.1: 24.2/25.4; 548.3: 23.7/24.7; 586.6: 22.9/23.8; 652.3: 21.0/22.0. Electron microprobe analyses give (wt.%): Cu 6.24(25), Ag 4.18(9), Fe 9.95(83), Zn 4.46(91), Hg 1.22(26), Tl 26.86(62), As 19.05(18), Sb 0.63(6),S 25.39(47), total 97.98(72). On the basis of 12 atoms per formula unit, the chemical formula of ferrostalderite is Cu0.75(2)Ag0.30(1)Fe1.36(10)Zn0.52(11)Hg0.05(1)Tl1.00(1)[As1.94(4)Sb0.04(1)]∑1.98(4)S6.04(4). The new mineral is tetragonal, space group I4̄2 m, with a = 9.8786(5), c = 10.8489(8) Å, V = 1058.71(11) Å3, Z = 4. The main diffraction lines of the calculated powder diagram are [d (in Å), intensity, hkl]: 4.092, 70, 211; 3.493, 23, 220; 3.396, 35, 103; 3.124, 17, 310; 2.937, 100, 222; 2.656, 19, 321; 2.470, 19, 400; 2.435, 33, 303. The crystal structure of ferrostalderite has been refined by Xray single-crystal data to a final R1= 0.050, on the basis of 1169 reflections with F0 > 4σ(F0). It shows a three dimensional framework of (Cu,Fe)-centred tetrahedra (1M1 + 2 M2), with channels parallel to [001] hosting disymmetric TlS6and (As,Sb)S3 polyhedra. Ferrostalderite is derived from its isotype stalderiteM1CuM2Zn2TlAs2S6through the homovalent substitution M2Zn2+ → M2Fe2+. The ideal crystal-chemical formula of ferrostalderite isM1CuM2Fe2TlAs2S6.

AbstractLithium mineralization is common in the Central Iberian Zone and, to a lesser extent, in the Galizia-Trás-OsMontes Zone of Spain and Portugal, occurring along a ∼500 km-long NNW-SSE striking belt. There are different styles of Li mineralization along this belt; they are mainly associated with aplite-pegmatite bodies and, to a much lesser extent, with veins of quartz and phosphate. Lithium mineralization in the Central Iberian Zone may be classified into four types: aplite-pegmatite dykes occurring in pegmatitic fields, Li mineralization associated with leucogranitic cupolas, beryl-phosphate pegmatites and quartz-montebrasite veins. The main Li minerals of these bodies include Li-mica, spodumene and/or petalite in the pegmatitic fields and leucogranitic cupolas; triphylite–lithiophilite in the beryl-phosphate pegmatites, and amblygonite–montebrasite in the quartz-montebrasite veins. The origin of these different styles of mineralization is considered to be related to differentiation of peraluminous melts, which were generated by partial melting of metasedimentary rocks during the Variscan orogeny. On the basis of paragenesis and chemical composition, the pegmatitic fields and Li mineralization associated with granitic cupolas record the highest fractionation levels, whereas the beryl-phosphate pegmatites and quartz-montebrasite veins show lower degrees of fractionation. There are a number of textural and mineralogical indicators for Li exploration in the Central Iberian Zone and in the Galizia-Trás-Os-Montes Zone, with the highest economic potential for Li being in the pegmatite fields.

AbstractIGFs are critical for normal intrauterine and childhood growth and sustaining health throughout life. We showed previously that the production of IGF-1 and IGF-2 requires interaction with the chaperone glucose-regulated protein 94 (GRP94) and that the amount of secreted IGFs is proportional to the GRP94 activity. Therefore, we tested the hypothesis that functional polymorphisms of human GRP94 affect IGF production and thereby human health. We describe a hypomorphic variant of human GRP94, P300L, whose heterozygous carriers have 9% lower circulating IGF-1 concentration. P300L was found first in a child with primary IGF deficiency and was later shown to be a noncommon single-nucleotide polymorphism with frequencies of 1%–4% in various populations. When tested in the grp94−/− cell-based complementation assay, P300L supported only approximately 58% of IGF secretion relative to wild-type GRP94. Furthermore, recombinant P300L showed impaired nucleotide binding activity. These in vitro data strongly support a causal relationship between the GRP94 variant and the decreased concentration of circulating IGF-1, as observed in human carriers of P300L. Thus, mutations in GRP94 that affect its IGF chaperone activity represent a novel causal genetic mechanism that limits IGF biosynthesis, quite a distinct mechanism from the known genes in the GH/IGF signaling network.

Abstract
Recent genome-wide association studies have identified several single nucleotide polymorphisms in the forkhead box E1 gene (FOXE1) locus, which are strongly associated with the risk for thyroid cancer. In addition, our recent work has demonstrated FOXE1 overexpression in papillary thyroid carcinomas. To assess possible contribution of Foxe1 to thyroid carcinogenesis, transgenic mice overexpressing Foxe1 in their thyroids under thyroglobulin promoter (Tg-Foxe1) were generated. Additionally, Tg-Foxe1 mice were exposed to x-rays at the age of 5 weeks or crossed with Pten+/− mice to examine the combined effect of Foxe1 overexpression with radiation or activated phosphatidylinositol-3-kinase/Akt pathway, respectively. In 5- to 8-week-old Tg-Foxe1 mice, severe hypothyroidism was observed, and mouse thyroids exhibited hypoplasia of the parenchyma. Adult 48-week-old mice were almost recovered from hypothyroidism, their thyroids were enlarged, and featured colloid microcysts and multiple benign nodules of macrofollicular-papilloid growth pattern, but no malignancy was found. Exposure of transgenic mice to 1 or 8 Gy of x-rays and Pten haploinsufficiency promoted hyperplastic nodule formation also without carcinogenic effect. These results indicate that Foxe1 overexpression is not directly involved in the development of thyroid cancer and that proper Foxe1 dosage is essential for achieving normal structure and function of the thyroid.
Dose-dependent fluoxetine effects on boldness in male Siamese fighting fish

Published: March 2016

ABSTRACTAs the use of pharmaceuticals and personal care products (PPCPs) continues to rise, these compounds enter the environment in increasing frequency. One such PPCP, fluoxetine, has been found in detectable amounts in aquatic ecosystems worldwide, where it may interfere with the behavior of exposed organisms. Fluoxetine exposure has been found to influence boldness and exploration in a range of fish species; however, how it might alter behavior in multiple contexts or over time is rarely examined. To this end, the effects of fluoxetine on boldness over time were studied in male Siamese fighting fish. Three different groups of males (0, 0.5 and 5 µg l−1 fluoxetine) were tested in multiple boldness assays (empty tank, novel environment and shoal) once a week for 3 weeks to collect baseline measures and then at three different time points post-exposure. The effects of these varying exposure amounts on behavior were then examined for overall response, consistency and across-context correlations. Unexposed males were bolder in all contexts, were more consistent within a context, and had stronger between-context correlations than exposed males. Fluoxetine had dose-dependent effects on behavior, as males that received the higher dose exhibited greater behavioral effects. This study stresses the potential fitness consequences of fluoxetine exposure and suggests that examining behavioral effects of PPCPs under different dosing regimens and in multiple contexts is important to gain an increased understanding of how exposure affects behavior.
