Abstract
Essentials The association of body weight and patient-important outcomes remains unknown. Phase III randomized controlled trials of direct oral anticoagulants (DOACs) were searched. Risk of outcomes varying among body weight subgroups is not attributable to anticoagulant type. Dose adjustment of DOACs, outside that recommended, is unlikely to improve the outcomes. Click to hear Dr Braunwald's perspective on antithrombotic therapy in cardiovascular disease SUMMARY: Background Concerns have arisen in direct oral anticoagulant (DOAC)-treated patients about safety and efficacy in extremes of body weight. The aims of this systematic review were to investigate the association of body weight and patient-important outcomes in patients treated with DOACs or warfarin, and to demonstrate the fixed-dose effect of DOACs. Methods MEDLINE and EMBASE were searched until November 2016. Phase III randomized controlled trials (RCTs) using DOACs in atrial fibrillation (AF) and acute venous thromboembolism (VTE) were included. Relative risk and 95% confidence interval were calculated. The pooled estimates were performed using a Mantel-Haenszel random effects model. Results A total of 11 phase III RCTs were included. Low body weight was associated with increased risk of thromboembolism compared with non-low body weight (relative risk [RR], 1.57; 95% confidence interval [CI], 1.34-1.85). High body weight was not associated with risk of thromboembolism compared with non-high body weight (RR, 0.88; 95% CI, 0.63-1.23). The subgroup of AF patients with high body weight had a lower risk of thromboembolism compared with non-high body weight (RR, 0.43; 95% CI, 0.28-0.67). Bleeding outcomes were comparable for all body weight comparisons. There were no clear interactions between types of anticoagulant in all outcomes. Conclusion The pooled effect of both the DOAC and comparison arms was likely to be attributable to differences in baseline thrombotic risk in each body weight category, rather than an effect of the type or dose of DOAC used for each indication. Dose adjustment of DOACs, outside that recommended in the package insert, is unlikely to improve safety or efficacy.

Abstract
Tyrosine aminotransferase (TAT) catalyzes the transamination of tyrosine to p-hydroxyphenylpyruvate. Accumulation of tyrosine in the body due to a genetic mutation in the TAT gene causes tyrosomia type II in humans. The TAT gene is regarded as a model for studying steroid-inducible factors regulating a variety of biological functions of TAT. However, little is known of the effects of estrogen on the expression of the TAT gene in chickens. Therefore, in the present study, we identified expression of the avian TAT gene in various organs. The results showed the TAT was detected predominantly in the liver and reproductive organs including testis, oviduct, and ovary. Specifically, TAT mRNA was expressed abundantly in the glandular and luminal epithelia of the oviducts in response to endogenous and exogenous estrogens which also induce dramatic morphological changes in the oviduct of chickens. In addition, target microRNAs of TAT (miR-1460, miR-1626-3p, miR-1690-5p, and miR-7442-3p) were found to modulate expression of the TAT gene. Especially, miR-1690-5p influenced TAT gene transcription by binding directly to its 3'-UTR region. Moreover, the expression of TAT was abundant in glandular epithelia of cancerous but not normal ovaries from laying hens. Taken together, our findings suggest that TAT plays an important role in the cytodifferentiation of oviducts in response to estrogen and in the progression of ovarian cancer in chickens.

Abstract
The self-paced maximal oxygen uptake (VO2max) test (SPV), which is based on the Borg 6-20 Ratings of Perceived Exertion (RPE) scale, allows participants to self-regulate their exercise intensity during a closed-loop incremental maximal exercise test. As previous research has assessed the utility of the SPV test within laboratory conditions, the purpose to this study was to assess the effect of trial familiarisation on the validity and reproducibility of a field-based, SPV test. In a cross-sectional study, fifteen men completed one laboratory-based graded exercise test (GXT) and three field-based SPV tests. The GXT was continuous and incremental until the attainment of VO2max. The SPV, which was completed on an outdoor 400m athletic track, consisted of five x 2 min perceptually-regulated (RPE11, 13, 15, 17 and 20) stages of incremental exercise. There were no differences in the VO2max reported between the GXT (63.5±10.1 ml·kg(-1)·min(-1)) and each SPV test (65.5±8.7, 65.4±7.0 and 66.7±7.7 ml·kg(-1)·min(-1) for SPV1, SPV2 and SPV3, respectively; P>.05). Similar findings were observed when comparing VO2max between SPV tests (P>.05). High intraclass correlation coefficients were reported between the GXT and the SPV, and between each SPV test (≥.80). Although participants ran faster and further during SPV3, a similar pacing strategy was implemented during all tests. This study demonstrated that a field-based SPV is a valid and reliable VO2max test. As trial familiarisation did not moderate VO2max values from the SPV, the application of a single SPV test is an appropriate stand-alone protocol for gauging VO2max.

Abstract
GaAs photovoltaics are promising candidates for indoor energy harvesting to power small-scale (≈1 mm2) electronics. This application has stringent requirements on dark current, recombination, and shunt leakage paths due to low-light conditions and small device dimensions. The power conversion efficiency and the limiting mechanisms in GaAs photovoltaic cells under indoor lighting conditions are studied experimentally. Voltage is limited by generation-recombination dark current attributed to perimeter sidewall surface recombination based on the measurements of variable cell area. Bulk and perimeter recombination coefficients of 1.464 pA/mm2 and 0.2816 pA/mm, respectively, were extracted from dark current measurements. Resulting power conversion efficiency is strongly dependent on cell area, where current GaAs of 1-mm2 indoor photovoltaic cells demonstrates power conversion efficiency of approximately 19% at 580 lx of white LED illumination. Reductions in both bulk and perimeter sidewall recombination are required to increase maximum efficiency (while maintaining small cell area near 1 mm2) to approach the theoretical power conversion efficiency of 40% for GaAs cells under typical indoor lighting conditions.

Abstract
Aquaporins (AQPs) are membrane proteins that passively deliver water across the plasma membrane to play an important role in maintaining cell shape. Members of the AQP family are distributed in most of the tissues in the human body and perform a variety of functions based on the water homeostasis suitable for each organ. However, there is little known about the expression and regulation of AQP family members in chickens. Therefore, we determined the expression of AQPs in various tissues of chickens. Among 13 isotypes, AQP3 was highly expressed in the chicken oviduct. Expression of AQP3 messenger RNA (mRNA) increased in the magnum (P < 0.001) and isthmus (P < 0.001) of chick oviducts treated with diethylstilbestrol. Consistent with these results, the localization of AQP3 was detected in the glandular and luminal epithelia of the magnum and isthmus of oviducts of diethylstilbestrol-treated chicks. In addition, the pattern of expression of AQP3 changed in an estrogen-dependent manner during the molting period. During the regenerative period of the oviduct after molting, expression of AQP3 mRNA increased coordinately with increasing concentrations of estradiol (P < 0.001), whereas expression of AQP3 mRNA decreased as concentrations of estradiol in plasma decreased in response to induced molting (P < 0.001). Also, expression of the AQP3 increased (P < 0.001) in cancerous ovaries of laying hens. In conclusion, AQP3 does not simply function to transport water into and out of cells but also appears to be closely involved in development of the chicken oviduct, which is regulated by estrogens. Furthermore, our results suggest AQP3 as a new diagnostic for early detection and treatment of epithelial cell-derived ovarian carcinomas.

Abstract
UNLABELLED ESSENTIALS: It is not known if D-dimer testing alone can safely exclude pulmonary embolism (PE). We studied the safety of using a quantitative latex agglutination D-dimer to exclude PE in 808 patients. 52% of patients with suspected PE had a negative D-dimer test and were followed for 3 months. The negative predictive value of D-dimer testing alone was 99.8%, suggesting it may safely exclude PE. SUMMARY BACKGROUND Strategies are needed to exclude pulmonary embolism (PE) efficiently without the need for imaging tests. Although validated rules for clinical probability assessment can be combined with D-dimer testing to safely exclude PE, the rules can be complicated or partially subjective, which limits their use. OBJECTIVES To determine if PE can be safely excluded in patients with a negative D-dimer without incorporating clinical probability assessment. PATIENTS/METHODS We enrolled consecutive outpatients and inpatients with suspected PE from four tertiary care hospitals. All patients underwent D-dimer testing using the MDA D-dimer test, a quantitative latex agglutination assay. PE was excluded in patients with a D-dimer less than 750 μg FEU L(-1) without further testing. PATIENTS with D-dimer levels of 750 μg FEU L(-1) or higher underwent standardized imaging tests for PE. All patients in whom PE was excluded had anticoagulant therapy withheld and were followed for 3 months for venous thromboembolism (VTE). Suspected events during follow-up were adjudicated centrally. RESULTS Eight hundred and eight patients were enrolled, of whom 99 (12%) were diagnosed with VTE at presentation. Four hundred and twenty (52%) patients had a negative D-dimer level at presentation and were not treated with anticoagulants; of these, one had VTE during follow-up. The negative predictive value of D-dimer testing for PE was 99.8% (95% confidence interval, 98.7-99.9%). CONCLUSIONS A negative latex agglutination D-dimer assay is seen in about one-half of patients with suspected PE and reliably excludes PE as a stand-alone test.

Abstract
BACKGROUND Direct oral anticoagulants (DOACs) are widely used as an alternative for warfarin. However, the impact of DOACs on mortality outcomes compared with warfarin remains unclear. OBJECTIVE To estimate the mortality outcomes in patients treated with DOACs vs. warfarin (or another vitamin K antagonist). METHODS MEDLINE, EMBASE and CENTRAL databases (inception to September 2014), conference abstracts and www.clinicaltrials.gov, were searched, without language restriction. Studies were selected if there were phase III, randomized trials comparing DOACs with warfarin in patients with non-valvular atrial fibrillation or venous thromboembolism. RESULTS Thirteen randomized controlled trials involving 102 707 adult patients were included in the analysis. The case-fatality rate of major bleeding was 7.57% (95% CI, 6.53-8.68; I(2) = 0%) in patients taking DOACs and 11.04% (95% CI, 9.16-13.07; I(2) = 33.3%) in patients taking warfarin. The rate of fatal bleeding in adult patients receiving DOACs was 0.16 per 100 patient-years (95% CI, 0.12-0.20; I(2) = 36.5%). When compared with warfarin, DOACs were associated with significant reductions in fatal bleeding (RR, 0.53; 95% CI, 0.43-0.64; I(2) = 0%), cardiovascular mortality (RR, 0.88; 95% CI, 0.82-0.94; I(2) = 0%) and all-cause mortality (RR, 0.91; 95% CI, 0.87-0.96; I(2) = 0%). CONCLUSIONS The use of DOACs compared with warfarin is associated with a lower rate of fatal bleeding, case-fatality rate of major bleeding, cardiovascular mortality and all-cause mortality.

Abstract
BACKGROUND Dabigatran, a direct thrombin inhibitor, is effective for the treatment of venous thromboembolism and the prevention of stroke and systemic embolism resulting from atrial fibrillation. The most effective way of reversing the anticoagulant effect of dabigatran in patients who have bleeding complications is unknown. OBJECTIVES To document the clinical outcomes of patients undergoing renal replacement therapy (RRT) for dabigatran-associated bleeding. METHODS We searched MEDLINE and EMBASE up to May 2015. Articles were selected if the patients presented with dabigatran-associated bleeding, underwent RRT for dabigatran removal, and reported an effect on bleeding. RESULTS The search yielded 22 studies representing 35 unique patient cases. The median patient age was 74.1 years (range, 56-94 years). Thirteen patients (37.1%) were female, and 32 (91.4%) patients received dabigatran for atrial fibrillation. Twenty-three patients (65.7%) underwent intermittent hemodialysis, 10 patients (28.6%) underwent continuous RRT (CRRT), and two patients underwent both intermittent hemodialysis and CRRT. Following RRT, there were significant reductions in dabigatran concentrations (P = 0.001). Rebound of the dabigatran concentration was reported in 12 (57.1%) patients following cessation of RRT. Hemostasis was reportedly achieved in 24 patients (70.6%), and 10 patients (29.4%) died because of bleeding. CONCLUSIONS In patients with dabigatran-associated bleeding, RRT appears to be effective in reducing dabigatran concentrations, and in case reports this has been associated with a reduction in the duration and/or severity of bleeding. However, a rebound in concentrations may be seen following withdrawal of RRT, suggesting that a prolonged course of RRT may be more effective.

Diethylstilbestrol regulates expression of avian apolipoprotein D during regression and recrudescence of the oviduct and epithelial-derived ovarian carcinogenesis.

[PMID: 25929245 DOI: 10.1016/j.domaniend.2015.03.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2015] [Revised: 03/08/2015] [Accepted: 03/27/2015] [Indexed: 01/02/2023]
Abstract
Apolipoprotein D (APOD) is a glycoprotein which is widely expressed in mammalian tissues. It is structurally and functionally similar to the lipocalins which are multiple lipid-binding proteins that transport hydrophobic ligands and other small hydrophobic molecules, including cholesterol and several steroid hormones. Although multiple functions for APOD in various tissues have been reported, its expression, biological function, and hormonal regulation in the female reproductive system are not known. Thus, in this study, we focused on correlations between APOD and estrogen during development, differentiation, regression, and regeneration of the oviduct in chickens and in the development of ovarian carcinogenesis in laying hens. Results of the present study indicated that APOD messenger RNA (mRNA) expression increased (P < 0.001) in the luminal and glandular (GE) epithelia of the chicken oviduct in response to diethylstilbestrol (a nonsteroidal synthetic estrogen). In addition, the expression of APOD mRNA and protein decreased (P < 0.001) as the oviduct regressed during induced molting, and gradually increased (P < 0.001) with abundant expression in GE of the oviduct during recrudescence after molting. Furthermore, APOD mRNA and protein were predominantly localized in GE of cancerous, but not normal ovaries from laying hens. Collectively, results of the present study suggest that APOD is a novel estrogen-stimulated gene in the chicken oviduct which likely regulates growth, differentiation, and remodeling of the oviduct during oviposition cycles. Moreover, up-regulated expression of APOD in epithelial cell-derived ovarian cancerous tissue suggests that it could be a candidate biomarker for early detection and treatment of ovarian cancer in laying hens and in women.

Abstract
The filter media in biofiltration systems play an important role in removing potentially harmful pollutants from urban stormwater runoff. This study compares the heavy metal removal potential (Cu, Zn, Cd, Pb) of five materials (potting soil, compost, coconut coir, sludge and a commercial mix) using laboratory columns. Total/dissolved organic carbon (TOC/DOC) was also analysed because some of the test materials had high carbon content which affects heavy metal uptake/release. Potting soil and the commercial mix offered the best metal uptake when dosed with low (Cu: 44.78 μg/L, Zn: 436.4 μg/L, Cd, 1.82 μg/L, Pb: 51.32 μg/L) and high concentrations of heavy metals (Cu: 241 μg/L, Zn: 1127 μg/L, Cd: 4.57 μg/L, Pb: 90.25 μg/L). Compost and sludge also had high removal efficiencies (>90%). Heavy metal leaching from these materials was negligible. A one-month dry period between dosing experiments did not affect metal removal efficiencies. TOC concentrations from all materials increased after the dry period. Heavy metal removal was not affected by filter media depth (600 mm vs. 300 mm). Heavy metals tended to accumulate at the upper 5 cm of the filter media although potting soil showed bottom-enriched concentrations. We recommend using potting soil as the principal media mixed with compost or sludge since these materials perform well and are readily available. The use of renewable materials commonly found in Singapore supports a sustainable approach to urban water management.

Abstract
OBJECTIVES Characterize bone loss in our newly developed severe contusion spinal cord injury (SCI) plus hindlimb immobilization (IMM) model and determine the influence of muscle contractility on skeletal integrity after SCI. METHODS Female Sprague-Dawley rats were randomized to: (a) intact controls, (b) severe contusion SCI euthanized at Day 7 (SCI-7) or (c) Day 21 (SCI-21), (d) 14 days IMM-alone, (e) SCI+IMM, or (f) SCI+IMM plus 14 days body weight supported treadmill exercise (SCI+IMM+TM). RESULTS SCI-7 and SCI-21 exhibited a >20% reduction in cancellous volumetric bone mineral density (vBMD) in the hindlimbs (p⋜0.01), characterized by reductions in cancellous bone volume (cBV/TV%), trabecular number (Tb.N), and trabecular thickness. IMM-alone induced no observable bone loss. SCI+IMM exacerbated cancellous vBMD deficits with values being >45% below Controls (p⋜0.01) resulting from reduced cBV/TV% and Tb.N. SCI+IMM also produced the greatest cortical bone loss with distal femoral cortical area and cortical thickness being 14-28% below Controls (p⋜0.01) and bone strength being 37% below Controls (p⋜0.01). SCI+IMM+TM partially alleviated bone deficits, but values remained below Controls. CONCLUSIONS Residual and/or facilitated muscle contractility ameliorate bone decrements after severe SCI. Our novel SCI+IMM model represents a clinically-relevant means of assessing strategies to prevent SCI-induced skeletal deficits.

Abstract
Hen egg protein (HEP21) is a 21-kDa secreted protein and has a single copy of the Ly6/uPAR domain. Although HEP21 is expressed primarily in the chicken oviduct, its biological function(s) in the reproductive system of chickens is not known. Thus, in the present study, we investigated expression patterns of HEP21 with respect to hormonal regulation, oviduct development, changes in expression in laying hens undergoing induced molting, and in the development of ovarian carcinogenesis in laying hens. Results of present study indicated that HEP21 messenger RNA (mRNA) expression increased (P < 0.001) in the chicken oviduct in response to estrogen. In situ hybridization analyses revealed expression of HEP21 mRNA predominantly in glandular (GE) and luminal epithelia of the magnum of the chicken oviduct in response to estrogen. The expression of HEP21 mRNA decreased (P < 0.001) as the oviduct regressed during induced molting and increased (P < 0.001) with recrudescence of the oviduct following molting. HEP21 mRNA was most abundant in GE of the oviduct during recrudescence, but not during oviduct regression following induced molting. Moreover, we found abundant expression of HEP21 in GE of cancerous ovaries, but not in normal ovaries of hens. Collectively, results of present study suggest that HEP21 is an estrogen-responsive gene in the oviduct of hens that likely regulates development of the chicken oviduct, and egg production and formation. Furthermore, there is increased expression of HEP21 in epithelial-derived ovarian cancer suggesting that HEP21 could be used for diagnosis and monitoring carcinogenesis in laying hens and in women.

Abstract
BACKGROUND A new transplantation program using kidneys after a small tumor excision was initiated in Western Australia in February 2007. The aim of this study was to report the outcomes over 5 years. METHODS Local urologists were encouraged to refer the kidney to the transplantation service when considering a radical nephrectomy. Recipients are selected according to strict criteria. Between February 2007 and February 2012 24 of 30 referred kidneys were restored for transplantation. Average donor age was 53.4 (range, 32-75) years while the recipients were 66.3 (range, 57-80) years. Twenty-one kidneys were restored after excision of a small tumor (<3.3 cm) and 3 kidneys were restored after being obtained from patients who had experienced complicated ureteric injuries secondary to laparotomy and colectomy. RESULTS Nineteen of 24 grafts displayed immediate function, 4 had delayed function, and 1 had nonfunction. The first 3 patients developed urinary leakages, which all resolved by subsequent management. One graft showed a pseudoaneurysm on the day 1 Doppler ultrasound, requiring interventional embolization. All patients but 1 have been off dialysis with satisfactory graft function; creatinine (Cr) levels ranged from 70 μmol/L to 330 μmol/L. There was no tumor recurrence on close follow-up from 6 to 55 months (median, 26). Three patients died due to other medical issues. CONCLUSION Kidneys could be restored from urologic disease for transplantation after excision of a small tumor with satisfactory outcomes at an average follow-up of 26 months. Frozen section is necessary to ensure the clearance of the tumor prior to transplantation. A modification of the surgical technique has minimized urine leakage and pseudoaneurysm formation after tumor resection.

Abstract
Abstract
Introduction: Breast cancer is a heterogeneous diseases, which is based on expression of the estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Using these factors, molecular subtype can be determined as luminal A, luminal B, HER2+, and TNBC. This is considered as an important prognostic factor. In breast cancer, age is the one of the important prognostic factors and prognosis is varied according to patients’ age. We performed this study to analyze the impact of molecular subtypes on prognosis of breast cancer according to patients’ age.
Patients and methods: We performed this study by using Korean Breast Cancer Society Registration Program data. Total 15,286 patients are included into this study, and they underwent surgery during the period Jan. 2001 to Dec. 2006. All patients were divided into two groups according to age (younger: age≤34, older: age≥35) and molecular subtypes were classified into four groups as follows: luminal A (ER+ and/or PR+, HER2-), luminal B (ER+ and/or PR+ HER2+), HER2+ (ER-, PR-, HER2+), and triple-negative (ER-, PR-, HER2-). We determined prognostic impact of molecular subtype on overall survivals (OS). Clinicopathologic results and OS were compared by chi-square test, Kaplan Meier test, and Cox's hazards model.
Results: Younger group more frequently had tumors with negative hormone receptor (ER-/PR-), worse prognostic factors and diagnosed with more advanced stage compared to older group. In univariate analysis, molecular subtype was not related with OS in younger group (p = 0.069), but not in older group (p<0.001). In multivariate analysis, molecular subtype was an independent prognostic factor for OS only in older group (p = 0.690 vs p<0.001).
Conclusion: In young breast cancer patients, less than 35 years, the impact of molecular subtypes on overall survival was not significant compared to other age group.

Abstract
Contusion spinal cord injury (SCI) animal models are used to study loss of muscle function and mass. However, parallels to the human condition typically have been confounded by spontaneous recovery observed within the first few post-injury weeks, partly because of free cage activity. We implemented a new rat model combining SCI with cast immobilization (IMM) to more closely reproduce the unloading conditions experienced by SCI patients. Magnetic resonance imaging was used to monitor hindlimb muscles' cross-sectional area (CSA) after SCI, IMM alone, SCI combined with IMM (SCI+IMM), and in controls (CTR) over a period of 21 days. Soleus muscle tetanic force was measured in situ on day 21, and hindlimb muscles were harvested for histology. IMM alone produced a decrease in triceps surae CSA to 63.9±4.9% of baseline values within 14 days. In SCI, CSA decreased to 75.0±10.5% after 7 days, and recovered to 77.9±10.7% by day 21. SCI+IMM showed the greatest amount of atrophy (56.9±9.9% on day 21). In all groups, muscle mass and soleus tetanic force decreased in parallel, such that specific force was maintained. Extensor digitorum longus (EDL) and soleus fiber size decreased in all groups, particularly in SCI+IMM. We observed a significant degree of asymmetry in muscle CSA in SCI but not IMM. This effect increased between day 7 and 21 in SCI, but also in SCI+IMM, suggesting a minor dependence on muscle activity. SCI+IMM offers a clinically relevant model of SCI to investigate the mechanistic basis for skeletal muscle adaptations after SCI and develop therapeutic approaches.

Abstract
Abstract
Backgrounds:18F-fluorodeoxyglucose positron emission tomography with computed tomography (18F-FDG PET/CT) is widely used for cancer evaluation and there are several studies which suggested maximum standard uptake value (SUVmax) may reflect the cancer patients' prognosis. Adenosine triphosphate-based chemotherapy response assay (ATP-CRA) is commonly used as a chemosensitivity assay modality for the treatment of various cancers in clinical settings and there have been several studies on its usefulness in breast cancer. We previously reported chemosensitivity (ATP-CRA) results might reflect patients' prognosis. So we supposed that SUVmax could reflect chemosenitivity (ATP-CRA) results of patients, so performed this study to analyze the relationship between PET/CT SUVmax and chemosenstivity (ATP-CRA) results of these drugs. Furthermore, we evaluated prognostic factors for breast cancer according to SUVmax.
Materials and Methods: 102 breast cancer patients, who underwent PET/CT and chemosensitive (ATP-CRA) test between December 2010 and April 2012, were enrolled in this study. We analyzed, retrospectively, the correlation between SUVmax of PET/CT and chemosenitivity (ATP-CRA) results of doxorubicin/paclitaxel. SUVmax according to prognostic factors were also assessed.
Results: Chemosensitivity (ATP-CRA) results of doxorubicin and paclitaxel have significant positive correlation with SUVmax. Their correlation coefficient were 0.236 (p = 0.020) and 0.216 (p = 0.030), respectively. Patients with larger tumor size, higher histologic and nuclear grade, estrogen receptor negative, progesterone receptor negative, HER2 positive, and Ki67 positive (≥14%) have higher mean SUVmax values (p < 0.05). In molecular subgroup analysis, triple negative group showed higher mean SUVmax values than luminal A group (p < 0.001).
Conclusion: Higher SUVmax values of PET/CT is correlated with better chemosensitive (ATP-CRA) results of doxorubicin and paclitaxel, and poor prognostic factors of breast cancer. However, examination of additional cases might be needed.

Abstract
BACKGROUND Warfarin and aspirin (acetylsalicylic acid [ASA]) are the most commonly used anticoagulant and antiplatelet drugs in the treatment of cardiovascular disease. OBJECTIVES To provide a pooled estimate of the bleeding risk from randomized controlled trials (RCTs) comparing warfarin and ASA at the dose ranges recommended in evidence-based guidelines. PATIENTS/METHODS Ovid MEDLINE, Embase and the Cochrane Library, up to September 2011, were searched for RCTs comparing bleeding rates in adult patients randomized to warfarin, target International Normalized Ratio (INR) 2.0-3.5, and ASA, 50-650 mg daily, with at least 3 months of follow-up. Pooled odds ratios (ORs) and associated 95% confidence intervals (CIs) were calculated with the inverse variance method and the random effects model. RESULTS Four thousand four hundred and forty-two abstracts were screened, resulting in eight included studies for final analysis. A pooled estimate derived from the 2904 patients enrolled indicated a trend towards an increase in major bleeding risk in those randomized to warfarin (OR 1.27; 95% CI 0.83-1.94). The pooled OR for intracranial hemorrhage in patients treated with warfarin vs. ASA was 1.64 (95% CI 0.71-3.78), and that for extracranial major bleeding was 1.03 (95% CI 0.61-1.75). Minor bleeding, from a 1748-patient sample, was more common in warfarin patients (OR 1.50; 95% CI 1.13-2.00). CONCLUSIONS This meta-analysis failed to find a statistically significant difference in major bleeding between warfarin, target INR 2.0-3.5, and ASA, 50-650 mg daily. The trend towards increased bleeding with warfarin appears to be explained by an excess of intracranial bleeding in warfarin patients.

Abstract
Phylogenetic analysis of the haemagglutinin (HA) gene shows that the influenza A(H1N1)2009 viruses collected in Hong Kong clustered in two main branches characterised by the E391E and E391K amino acids. The main branch E391K evolved in two sub-branches with N142D and S202T mutations that first appeared in March and July 2010, respectively, with the latter becoming the predominant strain. These genetic variants that emerged display similar antigenic characteristics. Concurrent with genetic surveillance, laboratories should continue monitoring the circulating viruses antigenically.
