Standardized one-day evaluation before urinary reconstructive surgery for neurogenic lower urinary tract dysfunction: Feasibility and impact on surgical strategy and care pathway. Prog Urol 2023; 33:1014-1025. [PMID: 37858377 DOI: 10.1016/j.purol.2023.09.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 09/16/2023] [Accepted: 09/26/2023] [Indexed: 10/21/2023]
Abstract
OBJECTIVES To describe a concept of standardized preoperative one-day evaluation before urinary reconstructive or diversion surgery for the treatment of neurogenic lower urinary tract (LUT) dysfunction, and to evaluate its feasibility and its impact on the care pathway. MATERIALS AND METHODS All patients who underwent a one-day standardized evaluation before a urinary reconstructive or derivation surgery for the treatment of neurogenic LUT dysfunction between January 2017 and December 2021 in our institution were included. Data were collected retrospectively from standardized reports. The main outcome was the rate of completion of the tests and consultations planned during this evaluation. Secondary outcomes included the findings from the one-day evaluation and changes in the urological surgical strategy at different time points within one year. RESULTS One hundred and thirty-one patients benefited from this one-day standardized evaluation. The overall completeness rate of the data collected was 77.5%, increasing from 62.3% in 2017 to 89.3% in 2021. The urological surgical plan was modified for 19.1% of patients following this preoperative evaluation. The indication was then confirmed for 114 patients (87.0%) by the multidisciplinary meeting and was carried out unchanged during the following year for 89 patients (67.9%). An associated colostomy procedure was proposed for 18.3% of patients and was finally performed in 11.5%. CONCLUSION A standardized multidisciplinary preoperative one-day evaluation before performing reconstructive or diversion surgery for the treatment of neurogenic LUT dysfunction seems feasible and makes it possible to optimize the surgical plan and adapt the course of care.

Abstract
Genotyping of Staphylococcus aureus isolated from mastitis has become a fundamental tool to understand its complex epidemiology and to evaluate spillover events. The aim of this study was to describe the frequency of genotypes of the S. aureus strains isolated from intramammary infections by spa typing technique, and to evaluate the association between genotypes and the ability to form biofilm under in vitro conditions. Sixty-six strains of S. aureus recovered from bovines intramammary infections on 56 dairy herds located in 14 municipalities of the department of Antioquia were characterized. The majority of strains (65/66) were isolated from milk samples collected from dairy cows with subclinical intramammary infections. Nineteen different spa types were found in this study, t521 (19.70%), t267 (15.15%), and t605 (12.12%) being the most frequent. The strains from the t605 spa type showed the highest biofilm production. The high frequency of spa types with zoonotic potential found in this study, identified cattle as an important reservoir of theses clones for people in close proximity, such as milkers and consumers of unpasteurized dairy products.

Abstract
Cetaceans adjust their distribution and abundance to encountered conditions across years and seasons, but we poorly understand such small-scale changes for many species, especially in winter. Crucial challenges confront some populations during this season, such as the high levels of fisheries-induced mortality faced by the common dolphin (Delphinus delphis) in the Northeast Atlantic shelves. For such species, understanding the winter fine-scale dynamics is crucial. We aimed to identify the dolphin distribution drivers during the winters of 2020 and 2021, with a focus on determining the lag between changes in oceanographic conditions and dolphin distribution. The changes were related to temporal delays specific to the nature and cascading effects that oceanographic processes had on the trophic chain. By determining the most important conditions and lags to dolphin distributions, we shed light on the poorly understood intrusions of dolphins within coastal waters during winter: they displayed a strong preference for the coastal-shelf waters front and extensively followed its spatial variations, with their overall densities increasing over the period and peaking in March-April. The results presented here provide invaluable information on the winter distribution dynamics and should inform management decisions to help reduce the unsustainable mortalities of this species in the by-catch of fisheries.

Abstract
Introduction: Inulin and its analog sinistrin are fructose polymers used in the food and pharmaceutical industries. In 2018, The French National Agency for the Safety of Medicines and Health Products (ANSM) decided to withdraw products containing sinistrin and inulin due to several reports of serious hypersensitivity reactions, including a fatal outcome. Objective: To assess the safety of inulin and sinistrin use in France. Methods: We searched multiple sources to identify adverse reactions (ARs) to inulin or sinistrin: first, classical pharmacovigilance databases including the French Pharmacovigilance (FPVD) and the WHO Database (VigiBase); second, data from a clinical trial, MultiGFR; third, data regarding current use in an hospital. All potential ARs to inulin or sinistrin were analyzed with a focus on hypersensitivity reactions and relationships to batches of sinistrin. Results: From 1991 to 2018, 134 ARs to inulin or sinistrin were registered in the FPVD or VigiBase. Sixty-three cases (47%) were classified as serious, and 129 cases (96%) were hypersensitivity reactions. We found an association between a batch of sinistrin and the occurrence of hypersensitivity reactions. During the MultiGFR clinical trial, 7 patients (7/163 participants) had an Adverse reaction; of these, 4 were hypersensitivity reactions including one case of grade 4 anaphylactic shock. In the hospital, no ARs were observed. In the literature, ARs to inulin and sinistrin are very rarely reported and mostly benign. Conclusion: Most ARs to inulin and sinistrin are hypersensitivity reactions that appear to be associated with sinistrin batches.

Abstract
Introduction Myocardial injury is frequently observed in patients hospitalized with Coronavirus disease 2019 (COVID-19) pneumonia. Different cardiac abnormalities have been reported during the acute COVID-19 phase but there is limited information on late cardiac sequelae in patients who have recovered from acute COVID-19 illness. Objective To document the presence and quantify the extent of myocardial functional alterations in patients hospitalized 6 months earlier for COVID-19 infection. Methods and results We conducted a prospective echocardiographic evaluation of 48 patients (58 ± 13 years, 69% male) hospitalized 6 ± 1 month earlier for a laboratory-confirmed and symptomatic COVID-19. Thirty-two (66.6%) had pre-existing cardiovascular risks factors (hypertension, T2DM or dyslipidemia) and three patients (6.2%) had a known prior myocardial infarction. Sixteen patients (33.3%) experienced myocardial injury during the index COVID-19 hospitalization as identified by a rise in cardiac troponin levels. Six months later, 60.4% of patients still reported clinical symptoms including exercise dyspnea for 56%. Echocardiographic measurements under resting conditions were not different between patients with vs. without myocardial injury during the acute COVID-19 phase. In contrast, low-level exercise (25 W for 3 minutes) induced a significant increase in the average E/e’ ratio (10.1 ± 4.3 vs. 7.3 ± 11.5, P = 0.01) and the systolic pulmonary artery pressure (33.4 ± 7.8 vs. 25.6 ± 5.3 mmHg, P = 0.02) in patients with myocardial injury during the acute COVID-19 phase. Sensitivity analyses showed that these alterations of left ventricular diastolic markers were observed regardless of cardiovascular disorders indicating SARS-CoV-2 infection as a primary cause. Conclusions Six months after the acute COVID-19 phase, significant cardiac diastolic abnormalities are observed in patients who experienced myocardial injury but not in patients without cardiac involvement.

Abstract
1. This study investigated the oxidative status of broilers fed diets containing selenium (Se) from 14 to 35 d of age and reared at two different constant temperatures. Measurements of oxidative status included blood glutathione peroxidase (GSH-Px) and plasma total antioxidant status (TAS). Other variables included feed intake (FI), weight gain (WG), feed conversion ratio (FCR), Se levels in breast and liver tissue, jejunal villus morphometry, percentage weight of organs in relation to body weight; apparent metabolisable energy adjusted for nitrogen (AMEn); dry matter retention (DMR); fat retention (FR) and nitrogen retention (NR).2. The experiment started at 14 d of age, when 240 birds were randomly allocated to 48 pens (12 pens in four rooms). Treatments included a control diet 1 (SFC; 209.4 g/kg CP and 12.98 MJ/kg ME and no added Se containing saturated fat); diet 2 (SFSe) the control plus 12.605 mg/kg Se additive; diet 3 (USFC) was a second control diet (208.2 g/kg CP and 13.10 MJ/kg ME with no added Se containing unsaturated fat as rapeseed oil); diet 4 (USFSe) was the latter control plus 12.605 mg/kg Se additive. Two rooms were kept at a standard temperature of 20°C (ST) and two rooms were kept at high temperature of 35°C (HT).3. A temperature x Se interaction existed for GSH-Px in birds reared at ST (P < 0.05), and these birds had the highest levels of Se in liver tissue (P < 0.05). Fat x Se interactions were evident in breast tissue with highest levels in USFSe (P < 0.05). Adding Se improved jejunal VH: CD in USFSe fed birds (P < 0.001).4. Birds reared at ST had higher FI and WG than those reared at HT (P < 0.001), and had lower FCR than those reared at HT (P < 0.05). AMEn (MJ/kg DM) and FR were higher in birds fed USF diets, and lowest in birds fed SF (P < 0.50 and P < 0.001 respectively). NR was highest in birds raised at ST (P < 0.50).5. Broiler growth performance was reduced by HT. Oxidative status and Se in liver tissue was improved by adding Se in both diets.

Abstract
1. This study examined the effects of different dietary sources and levels of selenium (Se) on growth performance, hepatic and breast meat Se content, glutathione peroxidase (GSH-Px) activity and total antioxidant status (TAS) in blood, when fed to broilers from 14 to 35 d of age and reared at two different temperatures (20°C and 35°C). 2. Five hundred and sixty male Ross 308 broilers were reared in a single floor pen and fed the same proprietary starter diet from 0 to 14 d age (229.9 g/kg CP and 12.67 MJ/kg ME, without Se supplementation). 3. The experiment started at 14 d age, and the birds randomly assigned to 112 raised-floor pens (0.36 m2 area, 5 birds/pen). Each of the seven experimental diets were offered to birds in 16 pens within four rooms. Two rooms were at 20°C and two rooms were maintained at 35°C. The experimental diets were fed from 14 to 35 d age and contained 214.9 g/kg CP and 13.11 MJ/kg ME. The experimental diets were as follows; control diet containing background Se only (0.189 mg/kg; C); low level sodium selenite (0.376 mg/kg; LSS): high level sodium selenite (0.558 mg/kg; HSS); low level commercial B Traxim® Se (0.244 mg/kg) (LBT); high level B Traxim® Se (0.448 mg/kg; HBT); low level selenised yeast (0.290 mg/kg; LSY); high level selenised yeast (0.487 mg/kg; HSY). 4. Birds consumed more when raised at 20°C compared to birds reared at 35°C (P ≤ 0.05). Birds fed lower Se level reared at 35°C had higher weight gain versus those fed higher Se level (P < 0.05). Birds fed SY had the lowest feed intake, weight gain and FCE (P < 0.05). The greatest GSH-Px activity was observed in birds fed SS diets (P < 0.001). There were interactions between diet x level for TAS, which were highest in birds fed LBT compared to birds fed HBT (P < 0.05). Breast Se content was higher in birds fed HSY compared to LSY (P < 0.001). The highest hepatic Se was seen in birds fed SY and lowest in C (P < 0.001). 5. Birds fed BT diets showed similar levels of Se to those birds fed inorganic Se, and similar levels of GSH-Px to birds fed SY. Further comparative work with broilers fed BT and other Se supplemented diets may elucidate the findings from this report.

Abstract
1. This study was conducted to determine the effect of different sources of selenium (Se) on breast and liver tissue deposition, apparent metabolisable energy (AME), growth performance and antioxidant status of broilers, measured as Se content in liver and breast tissues and glutathione peroxidase (GSH-Px) in blood, when used in 0-35 d broiler chicken diets. 2. A total of 200 male Ross 308 broilers were used in the feeding trial, which comprised two dietary phases, a starter from 0 to 21 d and finisher from 21 to 35 d of age. Four treatments with 10 replications each were used. A control diet (C) was formulated that was sufficient in protein and energy (230 and 215 g/kg of crude protein and 12.67 and 13.11 MJ/kg of metabolisable energy, respectively), for both phases, but contained background Se only from the feed ingredients. Diet 2 (IS) was supplemented with 10.35 g/t inorganic, elemental source of Se. Diet 3 (SY) was supplemented with 136.36 g/t selenised yeast, an organic source derived from Saccharomyces cerevisiae. Diet 4 (SS) was supplemented with 0.666 g/t sodium selenite, an inorganic source. 3. Birds fed the SY diet consumed less and weighed less than those fed IS or C (P < 0.05; 0-35 d of age), but there was no difference compared to birds fed SS diets. There were no differences in FCR or dietary AME between broilers fed different Se sources. All diets containing supplementary Se increased concentrations in the liver and breast muscle, and for GSH-Px levels in blood compared to birds fed the C diet (P < 0.001). Birds fed SY diets had greater Se levels in liver and breast tissues compared to birds fed any of the other diets (P < 0.001). 4. Diets supplemented with Se had variable effects on broiler growth performances and antioxidant status. Feeding Se from a yeast source has higher transfer into breast tissues. Feeding different sources and levels of Se to birds in a more challenging situation to induce oxidative stress may bring more conclusive results.

Abstract
Abstract
Introduction
Hypertension is one of the major contributors to cardiac diastolic dysfunction as observed in patients with heart failure and preserved ejection fraction. Different therapeutics strategies have been proposed to control blood pressure (BP) but their independent impact on cardiac function remain undetermined. In patients referred to our center for uncontrolled hypertension, we compared changes in cardiac parameters between two strategies consisting of sequential nephron blockade with intensive diuretics (NBD) or sequential renin angiotensin blockade (RAB).
Purpose
To determine evolution of BNP levels and echocardiographic (TTE) parameters of diastolic dysfunction according to strategies to control BP.
Methods
After 4-weeks treatment with 300mg irbesartan + 12.5mg hydrochlorothiazide + 5mg amlodipine, 140 patients with uncontrolled hypertension were randomized to either complete nephron blockade with sequential introduction of 25mg spironolactone, 20 to 40mg furosemide and 5mg amiloride (NBD group, n=74) or complete RAAS blockade with 5 to 10mg ramipril and 5 to 10mg bisoprolol (RAB group, n=67). BNP levels and TTE parameters according to ESC guidelines were assessed at baseline and week 12.
Results
BNP levels were not significantly different in the two groups at baseline (mean±SD 30.1±37.0pg/mL in NBD versus 22.6±22.3pg/mL in RAB, p=0.147) but significantly decreased in NBD at week 12 (20.1±22.7pg/mL in NBD versus 55.2±60.4pg/mL in RAB, p<0.0001). At week 12, only 9 (12%) patients in NBD presented BNP levels >35pg/mL versus 37 (55%) in RAB (p<0.001).
Concordantly, TTE parameters such as left ventricular end-diastolic diameter (mean±SD, 49±4mm in NBD and 52±5mm in RAB, p=0,004) and left atrial area (16.9±3.6cm2 in NBD and 19.1±3.7cm2 in RAB, p=0,003) improved significantly in NBD group. The proportions of patients presenting ≥2 criteria of diastolic dysfunction according to ESC guidelines in NBD and RAB group respectively were 31.2% and 19.3% at baseline vs. 3.1% and 32.2% after 12 weeks (p=0.001). In a multivariate analysis, NBD treatment was significantly associated with a decline in BNP levels (p<0.01) even after adjustment on daytime systolic BP lowering, heart rate, renal function, age and gender.
Conclusion
In patients with uncontrolled hypertension, intensive nephron blockade with sequential addition of diuretics improves markers of diastolic dysfunction independently of BP lowering.

Abstract
INTRODUCTION To compare non-continent urinary diversion (NCUD) and other bladder managements in patients with multiple sclerosis (MS), in terms of satisfaction and burden of care. MATERIAL AND METHODS All patients with MS that were proposed a NCUD in our center for refractory lower urinary tract disorders between January 2005 and March 2018 were eligible. Patients were attributed to two distinct groups: "NCUD" and "Other bladder management". The primary endpoint was the satisfaction related to the bladder management quoted by a numerical rating scale (NRS) from 0 to 10. The secondary endpoints included, among other things, the evaluation of the burden of care associated with the bladder management. RESULTS Twenty-three patients were included in the "NCUD" group and 11 in the "Other bladder management" group, with 4 patients pursuing with spontaneous voiding, 3 with intermittent catheterization, 2 that have undergone a sphincterotomy, 1 still performing self-intermittent catheterization and 1 with a supra-pubic catheter. The "NCUD" group had a significant higher NRS than the "Other bladder management" group (8.22±1.78 vs. 6.27±2.45; P=0.0056). The daily average duration of care was 16.42minutes in the "NCUD" group and 35.6minutes in the "Other bladder management" group (P=0.1111) CONCLUSION: This exploratory study, even if not conclusive, brings to light the preliminary results needed to elaborate a high level of evidence protocol regarding the satisfaction and the burden of care associated with NCUD in MS patients.

Abstract
Objective Immune checkpoint inhibitors are now a standard of care for the management of many metastatic cancers, including non-small-cell lung cancer. Pembrolizumab, a selective anti-PD-1 monoclonal antibody, augments the host antitumoural response. This hyperactivation of the immune system has side effects, the so-called immune-related adverse effects. The objective of this case report was to review and point out a new pattern of immune checkpoint inhibitor-associated pneumonitis. Case Description A 69-year-old woman with stage iv non-small-cell lung cancer receiving pembrolizumab presented for increased dyspnea. Pembrolizumab-related obstructive bronchiolitis was diagnosed based on a new severe obstructive disorder, without bronchodilator reversibility, and mosaic attenuation on angiography, without other identifiable causes. Summary To our knowledge, this is the first description of a case of pembrolizumab-induced obstructive bronchiolitis. Various patterns of immune checkpoint inhibitor-associated lung disease have been described, and bronchiolitis should be included in the differential diagnosis.

Abstract
Diepoxybutane (DEB) is the most potent active metabolite of butadiene, a regulated air pollutant. We previously reported the occurrence of DEB-induced, p53-dependent, mitochondrial-mediated apoptosis in human lymphoblasts. The present study investigated the role of the extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) pathway in DEB-induced apoptotic signaling in exposed human lymphoblasts. Activated ERK1/2 and mitogen-activated protein (MAP) kinase/ERK1/2 kinase (MEK) levels were significantly upregulated in DEB-exposed human lymphoblasts. The MEK inhibitor PD98059 and ERK1/2 siRNA significantly inhibited apoptosis, ERK1/2 activation, as well as p53 and phospho-p53 (serine-15) levels in human lymphoblasts undergoing DEB-induced apoptosis. Collectively, these results demonstrate that DEB induces apoptotic signaling through the MEK-ERK1/2-p53 pathway in human lymphoblasts. This is the first report implicating the activation of the ERK1/2 pathway and its subsequent role in mediating DEB-induced apoptotic signaling in human lymphoblasts. These findings contribute towards the understanding of DEB toxicity, as well as the signaling pathways mediating DEB-induced apoptosis in human lymphoblasts.

Abstract
Every year in France, nearly 50 infants live in a prison nursery with their mother. According to French law, infants can live with their mother in the prison nursery until they reach 18 months of age. The international community is concerned about the lack of validated social, medical and legal data on these infants living in prison. This was a retrospective and descriptive study. Medical and paramedical files of the General Council of Île-et-Vilaine, France, were studied. Every infant born between 1998 and 2013 while their mother was in prison were included. Fifty-four files were collected. The average length of stay was 6.2 months (n=54). The type of the mother's prison sentence was property damage in 40 % of cases, personal injury in 51.1 % of cases and both in 8.9 % of cases (n=45). The length of the mother's imprisonment was on average 45 months, ranging from 3 to 216 months (n=34). After prison, 42.9 % of the infants were placed in foster care and 57.1 % resided with their family (n=42). This child-mother incarceration could be an opportunity for positive intergenerational paramedical, medical and social services. The lack of data and problems collecting data restrict our knowledge of these families. This should motivate a national follow-up for these children.

Risk factor analysis of equine strongyle resistance to anthelmintics. INTERNATIONAL JOURNAL FOR PARASITOLOGY-DRUGS AND DRUG RESISTANCE 2017; 7:407-415. [PMID: 29149701 PMCID: PMC5727347 DOI: 10.1016/j.ijpddr.2017.10.007] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Revised: 10/26/2017] [Accepted: 10/30/2017] [Indexed: 12/01/2022]
Abstract
Intestinal strongyles are the most problematic endoparasites of equids as a result of their wide distribution and the spread of resistant isolates throughout the world. While abundant literature can be found on the extent of anthelmintic resistance across continents, empirical knowledge about associated risk factors is missing. This study brought together results from anthelmintic efficacy testing and risk factor analysis to provide evidence-based guidelines in the field. It involved 688 horses from 39 French horse farms and riding schools to both estimate Faecal Egg Count Reduction (FECR) after anthelmintic treatment and to interview farm and riding school managers about their practices. Risk factors associated with reduced anthelmintic efficacy in equine strongyles were estimated across drugs using a marginal modelling approach. Results demonstrated ivermectin efficacy (96.3% ± 14.5% FECR), the inefficacy of fenbendazole (42.8% ± 33.4% FECR) and an intermediate profile for pyrantel (90.3% ± 19.6% FECR). Risk factor analysis provided support to advocate for FEC-based treatment regimens combined with individual anthelmintic dosage and the enforcement of tighter biosecurity around horse introduction. The combination of these measures resulted in a decreased risk of drug resistance (relative risk of 0.57, p = 0.02). Premises falling under this typology also relied more on their veterinarians suggesting practitionners play an important role in the sustainability of anthelmintic usage. Similarly, drug resistance risk was halved in premises with frequent pasture rotation and with stocking rate below five horses/ha (relative risk of 0.53, p < 0.01). This is the first empirical risk factor analysis for anthelmintic resistance in equids. Our findings should guide the implementation of more sustained strongyle management in the field. 688 horses have been enrolled for Egg reduction rate measure. Ivermectin remains efficient but fendendazole is not any more. Evidence-based drenching and individual dosing lower resistance risk. Higher biosecurity is associated with higher drug efficacy. Premises with the least pasture constraints show higher drug efficacy.

Abstract
Essentials Rivaroxaban and dabigatran are substrates of the P-glycoprotein (P-gp) encoded by the ABCB1 gene. We tested the effect of ABCB1 polymorphisms and of a P-gp inhibitor on both drugs' pharmacokinetics. The ABCB1 genotype was not a clinically relevant determinant of both drugs' pharmacokinetics. Administration of P-gp inhibitors with dabigatran or rivaroxaban should be exercised with caution. SUMMARY Background The direct oral anticoagulants (DOACs) dabigatran and rivaroxaban are both substrates of the P-glycoprotein (P-gp) transporter, encoded by the ABCB1 gene. Rivaroxaban is metabolized by cytochrome P450 A4 (CYP3A4). Interindividual variability in DOAC exposure and frequent P-gp-associated drug-drug interactions have been described in patients. Objective To assess the influence of ABCB1 polymorphisms on the pharmacokinetics of dabigatran and rivaroxaban, associated or not with clarithromycin, a P-gp and CYP3A4 inhibitor. Methods Sixty healthy male volunteers, selected according to ABCB1 genotype (20 homozygous mutated, 20 heterozygous mutated, and 20 wild-type for haplotype 2677-3435), were included in this randomized, two-center, crossover study. All received sequentially a single dose of dabigatran etexilate (300 mg) and rivaroxaban (40 mg) associated or not with clarithromycin. Peak plasma concentration and area under the curve (AUC) were compared across the three ABCB1 genotypes. The effect of clarithromycin on dabigatran or rivaroxaban pharmacokinetics was assessed. Results Interindividual coefficients of variation for AUC were 77% for dabigatran and 51% for rivaroxaban. ABCB1 genotype did not significantly affect drug pharmacokinetics: AUC ratios between mutant-allele carriers and wild-type volunteers were 1.27 (95% confidence interval [CI] 0.84-1.92) and 1.20 (95% CI 0.96-1.51) for dabigatran and rivaroxaban, respectively. Clarithromycin coadministration led to a two-fold increase in both drugs' AUC, irrespective of ABCB1 genotype: ratios of geometric means were 2.0 (95% CI 1.15-3.60) and 1.94 (95% CI 1.42-2.63) for dabigatran and rivaroxaban, respectively. Conclusions ABCB1 genotype is not a significant determinant of interindividual variability in dabigatran and rivaroxaban pharmacokinetics. The levels of one drug did not predict the levels of the other. Coadministration of a P-gp/CYP3A4 inhibitor with dabigatran or rivaroxaban may warrant caution in patients at risk of overexposure.

Abstract
We study the dynamics of a linear, uniform, undamped string under harmonic base excitation, with an attachment consisting of either a spring–dashpot system or a vibration absorber. Mode complexity caused by the local damping of the attachment can lead to coexistence of vibrations and waves in the string. We consider either identical harmonic base motions at both ends or harmonic base excitation at one end. In the case of double harmonic base excitation, it is possible to choose the parameters of the attachment, so that the mode complexity is maximal in one part of the string (leading to travelling waves and elimination of vibrations) and almost zero in the other part (with standing waves or vibration modes). Similarly, for single base excitation, we analytically predict the parameters of the attachment that maximize mode complexity and enhance the interplay of vibrations and travelling waves in the string. Under such conditions, the system acts as a passive vibration confinement device, with induced energy being transmitted through travelling waves to a region where it is confined in the form of standing waves. Our results can be used for predictive design and reveal an unexpected new application of the classical linear vibration absorber.

Expression of both estrogen receptor-beta 1 (ER-β1) and its co-regulator steroid receptor RNA activator protein (SRAP) are predictive for benefit from tamoxifen therapy in patients with estrogen receptor-alpha (ER-α)-negative early breast cancer (EBC).

Abstract
BACKGROUND Roles of Estrogen Receptor-beta 1 (ER-β1) and its co-regulator Steroid Receptor RNA Activator Protein (SRAP) in breast cancer remain unclear. Previously, ER-β1 and SRAP expression were found positively correlated in breast cancer and, therefore, expression of these two molecules could characterize cancers with a distinct clinical outcome. PATIENTS AND METHODS ER-β1 and SRAP expression was determined by immunohistochemistry (IHC) in tissue microarrays from a randomized, placebo-controlled trial (NCIC-CTG-MA12), designed to determine the benefit of tamoxifen following chemotherapy in premenopausal early breast cancer (EBC). Expression was dichotomized into low and high using median IHC scores. Relationships with survival used Cox modeling. RESULTS In the whole cohort, ER-β1 and SRAP were not prognostic. However, high ER-β1 and SRAP significantly predicted tamoxifen responsiveness [overall survival, interaction test, P = 0.03; relapse-free survival (RFS), interaction test, P = 0.01]. Stratification by ER-α-status found predictive benefit only in ER-α-negative cases. The difference in RFS between tamoxifen and placebo was greater in patients whose tumors expressed both high SRAP and ER-β1[hazard ratio = 0.07; 95% confidence interval (CI) 0.01-0.41; P = 0.003] versus those with low SRAP or ER-β1 (interaction test, P = 0.02). The interaction test was not significant in ER-α-positive cohorts. CONCLUSIONS This study provides evidence that both ER-β1 and SRAP could be predictive biomarkers of tamoxifen benefit in ER-α-negative premenopausal EBC.
