Abstract
PURPOSE/OBJECTIVE(S) Several prospective trials in oligometastatic castration sensitive prostate cancer (omCSPC) have shown metastasis-directed therapy (MDT) can delay time to progression and initiation of androgen deprivation therapy (ADT) compared to observation. However, the optimal integration of ADT with MDT remains unclear. Here we report a multi-national, multi-institutional retrospective cohort of omCSPC treated with MDT to characterize the long-term outcomes of patients treated with MDT alone or in combination with ADT. MATERIALS/METHODS Patients with a controlled primary site and omCSPC (defined as ≤ 5 lesions on conventional imaging) treated with MDT with or without concurrent ADT and with at least 36 months follow-up were retrospectively screened across 13 institutions. The primary endpoints included biochemical progression free survival (bPFS) and radiographic progression free survival (rPFS) calculated using Kaplan-Meier method and stratified by treatment group (MDT alone vs MDT + ADT). Multivariable Cox regression was performed adjusted for variables found to be prognostic on univariate analysis. RESULTS Among 414 patients screened, a total of 263 patients treated between 2003 and 2018 met inclusion criteria and included. Of these, 105 received MDT alone and 158 received MDT+ADT, with median follow-up of 49.5 and 54.5 months, respectively. The majority were metachronous (90%) and had bone lesions (60%). Median ADT duration was 21.3 months (IQR 12.0- 31.9). Patients who received ADT vs. no ADT had poorer prognostic features including 23% vs. 1% synchronous (p<0.001), and 55% vs 40% Gleason 8-10 (p = 0.012). ADT use was associated with a better 5-year bPFS 24% vs 11% (p<0.0001) and rPFS 41% vs 29% (p<0.001). On multivariable Cox regression adjusting for post-MDT PSA nadir and salvage therapy, ADT use maintained significance for both bPFS (HR 0.51 (0.36, 0.71), p<0.001) and rPFS (HR 0.67, 95% CI 0.46-0.96, p = 0.03). CONCLUSION Long-term outcomes with MDT alone suggest a small proportion of patients experience sustained disease control. The addition of ADT appears to improve rPFS, however prospective studies are needed in order to allow for personalization of care in patients with omCSPC.

Abstract
Many situations can be considered as a crisis in radiotherapy (failure of equipment, absenteeism, excessive workload, errors, urgent care, pandemic, etc.). Such events are defined as difficult situations in the course of daily activity, they can at any time escape the vigilance of the concerned actors when they are not prepared for it. The crisis can induce a disruption of balance between the normal course of the radiation therapy and the obligation for the manipulators to reconcile the consequences of the ongoing crisis with the objective of taking charge of all patients scheduled for the program. The crisis and its management will inexorably cause stress, fatigue and, as a consequence, impact patient safety. Management has an essential role to play in maintaining team dynamics when a crisis occurs, the work environment may no longer be the same. The aim of this article is to describe these situations in order to highlight the needs of the teams and more specifically the needs of the radiation therapist. It highlights the organization of patient care in the event of crisis management (Covid-19), during palliative radiotherapy with an opportunity to develop advanced practice. The reflection on the ethical concern of the radiation therapist in the prioritization of patients leads us to analyze the knowledge of medical ethics provided during initial training. When they perform their duties, manipulators seem to be confronted with situations that give rise to ethical dilemmas. It is then a question of understanding how they reflect on their practice in order to make it evolve. Is the radiation therapist confronted with ethical issues in the course of his practice? What solutions can be implemented to deal with these issues?

Abstract
BACKGROUND Chronic myeloproliferative neoplasms (MPN) are recognized as a cause of pulmonary hypertension (pH). We ought to describe the prevalence and characteristics of PH in a cohort of MPN who were screened using transthoracic echocardiography (TTE). METHODS One hundred eighty-three newly diagnosed consecutive MPN patients were prospectively evaluated using TTE to detect PH. RESULTS Two patients were diagnosed with chronic eosinophilic leukemia, two patients had post-essential thrombocythemia (ET) myelofibrosis (MF), two patients had post-polycythemia vera (PV) MF, 11 patients had primary myelofibrosis (PMF), 28 patients had chronic myeloid leukemia (CML), 51 patients had PV, and 87 patients had ET. TTE was used to determine PH, and PH was suspected in 16 of 183 patients as follows: four with PV, seven with ET, two with PMF, and three with CML. Two patients with ET were excluded because of global cardiac failure. Three patients underwent right heart catheterization to confirm PH. The 14 (7.7%) patients with PH had no cardiac or lung disease that directly involved MPN in PH development. CONCLUSION In this large cohort of 183 MPN patients, TTE was used to diagnose PH, and 14 patients (7.7%) developed PH. This prevalence was lower than expected based on previously reported data, but it remains higher than in the general population.

Abstract
OBJECTIVES Recently, phase III trials assessed a new combination of lenalidomide, bortezomib, and dexamethasone (RVD) in induction therapy in transplantation-eligible multiple myeloma (MM) patients, before consolidation with RVD and lenalidomide maintenance. We present a retrospective study evaluating this approach with patients from the real life. METHODS We conducted a retrospective single-arm study to assess efficacy and safety of RVD combination in induction therapy before high-dose chemotherapy with melphalan followed by autologous stem cell transplantation, and RVD consolidation followed by lenalidomide maintenance, from February 2011 to May 2016. RESULTS Forty patients were enrolled. The mean age at diagnosis was 56 years. Median progression-free survival was 45 months, and median overall survival was 76 months. The only factor found associated with better PFS was a negative minimal residual disease (P < .01). Twenty-six (65%) patients experimented adverse events: 8 patients (20%) underwent 12 serious AE (≥grade 3). Treatment discontinuation occurred in 2 patients (5%) because of severe AE. CONCLUSION To our knowledge, this work provides the first evidence of the efficacy and the safety of RVD combination in patients treated in common practice.

Abstract
Autologous hematopoietic stem cell transplantation is the standard treatment for multiple myeloma and relapsed or refractory lymphomas. After autologous hematopoietic stem cell transplantation, hematologic reconstitution and infectious complications are the two most critical issues. Although many patients develop infectious complications after therapeutic intensification, it remains impossible to predict infection for each individual. The goal of this work was to determine and identify a predictive transcriptomic signature of systemic inflammatory response syndrome and/or sepsis in patients receiving autologous hematopoietic stem cell transplantation. High-throughput transcriptomic and bioinformatics analysis were performed to analyze gene expression modulation in peripheral blood mononuclear cells in 21 patients undergoing autologous hematopoietic stem cell transplantation for hematological malignancies (lymphoma or multiple myeloma). Transcriptomic analysis of peripheral blood mononuclear cells samples collected just after conditioning regimen identified an 11-gene signature (CHAT, CNN3, ANKRD42, LOC100505725, EDAR, GPAT2, ENST00000390425, MTRM8, C6orf192, LOC10289230, and XLOC-005643) that was able to early predict (at least 2-7 days before its occurrence) the development of systemic inflammatory response syndrome or sepsis. The possibility of systemic inflammatory response syndrome or sepsis occurrence early prediction (2-7 days before occurrence) opens up new therapeutic strategies based on preemptive antibiotic and/or antifungal prophylaxis adapted to the specific risk profile of each patient.

Abstract
Purpose Sentinel-lymph-node (SLN) resection seems to minimize systematic axillary-lymph-node dissection (sALND) side effects in operated breast cancer patients. We explored whether SLN resection achieves similar therapeutic outcomes as sALND but with fewer side effects. Methods A randomized, controlled, open-label trial with parallel-group design compared sALND restricted to cases with positive SLN biopsy (test arm, n = 774) versus SLN biopsy followed by sALND (control arm, n = 770).
Results The five-year overall survivals in control and test arms were 96.42 and 95.64% (P = 0.2925). The estimated difference was nearly zero (precisely, − 0.79%, one-tailed 95% confidence interval (CI) limit − 2.44%). In a multivariate Cox model, the adjusted hazard ratio in the test arm was HR 0.81 (upper 95% CI limit 1.17). Advanced age (HR 1.05 per additional year, CI [1.03–1.08]), negative progesterone receptor (HR 2.17 [1.35–3.45]), SLN metastasis (HR 1.69 [1.03–2.79]), and only one SLN identification technique (HR 4.14 [1.21–14.18]) were associated with lower survival. Patients with ≥ 1 severe side effect at 1 month in control and test arms were 173/703 = 24.6% [21.5–28.0%] and 91/693 = 13.1% [10.7–15.9%] (P < 0.001). The estimated sensitivity of SLN biopsy (control arm) was 145/178 = 81.5% [74.8–86.7%].
Conclusions Restricting ALND to cases with positive SLN biopsy does not affect the overall survival but reduces by 11.5% [7.5–15.6%] (P < 0.001) the risk of severe short-time side effects of sALND.

Abstract
In Dr. Turner's paper on the classification of insanity in the January number of the Journal occurs this passage: “It is from cases of this class” (epileptic insanity, psychasthenia, morbid obsessions, and impulse) “that subtle dialecticians seek to prove there may be disorder of conduct without disorder of mind.” As I am the only person who has ever made any distinction between disorder of conduct and disorder of mind, or has ever said that the one may be disordered without disorder of the other, it is manifest that I am the subtle dialecticians referred to by Dr. Turner, and I must express to him my obligation for justifying me in the future use of the royal We. We must point out to him, however, that after the manner and habit of members of this Association, he attributes to Us views that We have never expressed and never held. We have, indeed, taught for many years, and iterated and reiterated, that disorder of mind may exist without disorder of conduct, and this view is again expressed in Our paper published in this Journal in October, 1910, but We have never expressed the opinion, subtle dialecticians though We may be, that disorder of conduct ever exists apart from disorder of mind. Perhaps Dr. Turner will be so good another time as to verify his references.

Abstract
SAHA (vorinostat) is a histone deacetylase inhibitor approved by the USA Food and Drug Administration (FDA) for treating advanced refractory cutaneous T cell lymphomas. As SAHA alters the expression of many genes under control of the Sp1 transcription factor, we examined the effect of its association with the FDA-approved anticancer antibiotic Mithramycin A (MTR, plicamycin), a competitive inhibitor of Sp1 binding to DNA. Sézary syndrome (SS) cells, expanded ex vivo from peripheral blood mononuclear cells of 4 patients, were tested for their sensitivity to the drugs regarding cytotoxicity and differential responsive gene expression. Multivariate statistical methods were used to identify genes whose expression is altered by SAHA, MTR, and the synergist effect of the two drugs. MTR, like SAHA, induced the apoptosis of SS cells, while the two drugs in combination showed clear synergy or potentiation. Expression data stressed a likely important role of additive or synergistic epigenetic modifications in the combined effect of the two drugs, while direct inhibition of Sp1-dependent transcription seemed to have only limited impact. Ontological analysis of modified gene expression suggested that the two drugs, either independently or synergistically, counteracted many intertwined pro-survival pathways deregulated in SS cells, resistance of these tumors to intrinsic and extrinsic apoptosis, abnormal adhesion migration, and invasive properties, as well as immunosuppressive behavior. Our findings provide preliminary clues on the individual and combined effects of SAHA and MTR in SS cells and highlight a potential therapeutic interest of this novel pair of drugs for treatment of SS patients.

Abstract
When subjects learn a novel motor task, several sources of feedback (proprioceptive, visual or auditory) contribute to the performance. Over the past few years, several studies have investigated the role of visual feedback in motor learning, yet evidence remains conflicting. The aim of this study was therefore to investigate the role of online visual feedback (VFb) on the acquisition and retention stages of motor learning associated with training in a reaching task. Thirty healthy subjects made ballistic reaching movements with their dominant arm toward two targets, on 2 consecutive days using a robotized exoskeleton (KINARM). They were randomly assigned to a group with (VFb) or without (NoVFb) VFb of index position during movement. On day 1, the task was performed before (baseline) and during the application of a velocity-dependent resistive force field (adaptation). To assess retention, participants repeated the task with the force field on day 2. Motor learning was characterized by: (1) the final endpoint error (movement accuracy) and (2) the initial angle (iANG) of deviation (motor planning). Even though both groups showed motor adaptation, the NoVFb-group exhibited slower learning and higher final endpoint error than the VFb-group. In some condition, subjects trained without visual feedback used more curved initial trajectories to anticipate for the perturbation. This observation suggests that learning to reach targets in a velocity-dependent resistive force field is possible even when feedback is limited. However, the absence of VFb leads to different strategies that were only apparent when reaching toward the most challenging target.

Abstract
Objective: It has been suggested that the measurement of strength is inappropriate in patients with stroke, in large part because of the presence of abnormal synergy patterns. The aim of the present study was to characterize force production during multi-joint maximal exertion involving different combinations of activation between shoulder and elbow flexors and extensors. Design: Cross-sectional study. Setting: Rehabilitation centre. Subjects: A convenience sample of 16 chronic hemiparetic stroke subjects. Main outcome measures: Maximal torques in flexion and extension at the shoulder and the elbow were measured using static dynamometers (single-joint condition). In addition, the maximal forces produced at the wrist were measured in four directions in the sagittal plane requiring different torque combinations between shoulder and elbow flexors and extensors (multi-joint condition). Results: No difference was found across directions for the ratios of maximal forces (paretic/nonparetic) in the multi-joint condition (p = 0.227; mean ratios (9±SD) for each direction ranging from 0.599±0.23 to 0.689±0.27), suggesting that the ability to produce force did not change as a function of the required torque combination. In addition, relative torques (% of the maximal torque in the single-joint condition) exerted during the multi-joint exertions were similar on the paretic and the nonparetic side. Conclusions: These results do not support the assumption that force production is limited by abnormal synergy patterns between flexors and extensors at the shoulder and the elbow in hemiparetic patients.

Abstract
Sensorimotor reorganization is believed to play an important role in the development and maintenance of phantom limb pain, but pain itself might modulate sensorimotor plasticity induced by deafferentation. Clinical and basic research support this idea, as pain prior to amputation increases the risk of developing post-amputation pain. The aim of this study was to examine the influence of experimental tonic cutaneous hand pain on the plasticity induced by temporary ischemic hand deafferentation. Sixteen healthy subjects participated in two experimental sessions (Pain, No Pain) in which transcranial magnetic stimulation was used to assess corticospinal excitability in two forearm muscles (flexor carpi radialis and flexor digitorum superficialis) before (T0, T10, T20, and T40) and after (T60 and T75) inflation of a cuff around the wrist. The cuff was inflated at T45 in both sessions and in the Pain session capsaicin cream was applied on the dorsum of the hand at T5. Corticospinal excitability was significantly greater during the Post-inflation phase (p=0.002) and increased similarly in both muscles (p=0.861). Importantly, the excitability increase in the Post-inflation phase was greater for the Pain than the No-Pain condition (p=0.006). Post-hoc analyses revealed a significant difference between the two conditions during the Post-inflation phase (p=0.030) but no difference during the Pre-inflation phase (p=0.601). In other words, the corticospinal facilitation was greater when pain was present prior to cuff inflation. These results indicate that pain can modulate the plasticity induced by another event, and could partially explain the sensorimotor reorganization often reported in chronic pain populations.

Abstract
OBJECTIVE To study the efficacy and safety of micafungin for prophylaxis of invasive fungal infections in patients undergoing induction chemotherapy for acute myeloid leukemia. PATIENTS AND METHODS A prospective observational single-center study of 41 patients from the hematology department between May 2012 and April 2015. Micafungin was administered once daily from the first day of induction chemotherapy to the end of the neutropenic phase. RESULTS Neither Candida nor Aspergillus infection was documented in our 41 patients from the first day of micafungin infusion to the end of the neutropenic phase. Patients were followed for three months after discontinuation of micafungin and none of them contracted an invasive fungal infection. Only one patient presented with grade III-IV hepatic and ionic toxicities. CONCLUSION Micafungin is associated with a good safety profile and is an interesting option for preventing invasive fungal infections in the high-risk population of patients presenting with hematological disorders.

Abstract
The purpose of this article is to convey the findings of two studies related to the perception of past, present and future roles, the value attributed to these roles as well as the role patterns. Both studies were conducted with adults who have schizophrenia and are involved in a rehabilitation or work program. Data were collected from two sources: 1) secondary analysis of a study related to the methodology for validating the French translation (Hachey, Jumoorty, & Mercier, 1995) of the “Role Checklist”, (Barris, Oakley, & Kielhofner, 1988) and 2) a research project on the perception of roles and quality of life. Results showed that the dominant roles assumed by participants regardless of time were family member, friend, home maintainer and hobbyist. The most valued roles were those of friend, worker, and family member. The discussion will address the questions asked and elucidate the role patterns. The conclusion underlines the importance, for occupational therapists and health professionals, of including roles in the daily lives of their clients, taking into consideration the ones they value most highly.

Abstract
Introduction Community-acquired meningitis is a monomicrobial infection caused by either viruses or bacteria in the vast majority of patients. We report here one exceptional case of a patient with mixed bacterial meningitis due to Streptococcus pneumoniae and Streptococcus pyogenes. Case presentation We report the case of a 68-year-old immunocompromised Caucasian man suffering from otitis and then meningitis caused by Streptococcus pneumoniae and Streptococcus pyogenes. Bacteria were undistinguishable by direct microscopic examination of the cerebrospinal fluid. He responded well to treatment with cefotaxime and dexamethasone, with no sequelae observed at the 4-month follow-up. Conclusions This first reported case of mixed S. pneumoniae and S. pyogenes meningitis illustrates the life-threatening consequences of barotrauma in immunocompromised patients suffering from otorhinolaryngeal infections.

Abstract
Azacitidine is a mainstay for treating hematological disorders. Azacitidine is metabolized by cytidine deaminase, coded by a highly polymorphic gene. Here, we present two elderly patients with opposite clinical outcomes after azacitidine treatment. First, an acute myeloid leukemia patient showed life-threatening toxicities, but outstanding complete remission, after a single round of azacitidine. Further investigations showed that this patient was cytidine deaminase 79A>C (rs2072671) homozygous with a marked deficient phenotype. Next, a chronic myelomonocytic leukemia patient displayed complete lack of response despite several cycles of azacitidine. This patient had a rapid-deaminator phenotype linked to the -31delC deletion (rs3215400). These polymorphisms lead to opposite clinical outcomes in patients with myelodysplastic syndromes treated with azacitidine, thus suggesting that determining cytidine deaminase status could help to forecast clinical outcome.

Abstract
Closely related sympatric species commonly develop different ecological strategies to avoid competition. Ctenomys minutus and C. flamarioni are subterranean rodents parapatrically distributed in the southern Brazilian coastal plain, showing a narrow sympatric zone. To gain understanding on food preferences and possible competition for food resources, we evaluated their diet composition performing DNA metabarcoding analyzes of 67 C. minutus and 100 C. flamarioni scat samples, collected along the species geographical ranges. Thirteen plant families, mainly represented by Poaceae, Araliaceae, Asteraceae and Fabaceae, were identified in the diet of C. minutus. For C. flamarioni, 10 families were recovered, with a predominance of Poaceae, Araliaceae and Asteraceae. A significant correlation between diet composition and geographical distance was detected in C. minutus, whereas the diet of C. flamarioni was quite homogeneous throughout its geographical distribution. No significant differences were observed between males and females of each species. However, differences in diet composition between species were evident according to multivariate analysis. Our results suggest some level of diet partitioning between C. flamarioni and C. minutus in the sympatric region. While the first species is more specialized on few plant items, the second showed a more varied and heterogeneous diet pattern among individuals. These differences might have been developed to avoid competition in the region of co-occurrence. Resource availability in the environment also seems to influence food choices. Our data indicate that C. minutus and C. flamarioni are generalist species, but that some preference for Poaceae, Asteraceae and Araliaceae families can be suggested for both rodents.

Abstract
Voice and speech impairments are frequent in Parkinson's disease, particularly when the disease is at an advanced stage. These impairments affect spoken communication and may become a serious disability for someone with Parkinson's disease. Many studies based on auditory-perceptual or acoustic methods have been carried out to characterize dysarthria. The heterogeneity of evaluation methods and experimental bias however make results difficult to understand. For instance, in terms of phonatory impairments and with regard to F0, results are contradictory: PD speech may be characterized by either higher F0 or lower F0 compared to control subjects, or there may be no difference at all between the two population. In this study, we aim to provide a conceptual and methodological framework which allows for interpreting the results obtained from 44 speakers (29 PD and 15 control subjects) in relation to physiological (gender, age, PD subjects' pharmacologic state) and linguistic (speech production tasks) constraints. For the present corpus, we did not observe any F0 mean difference between the two groups. Our results however reveal a significant increase in F0 mean in PD subjects under L-dopa. We assume a double and opposite effect on F0 mean during drug withdrawal: low sub-glottal pressure, due to PD, results in a decrease in F0, while laryngeal rigidity leads to an increase in F0. These two effects thus mutually annihilate. Under L-Dopa, however, the drug effect increases sub-glottal pressure, which combined with an increase in F0 due to rigidity, leads to a global increase in F0.

Abstract
AIMS Escherichia coli is able to reduce azo compounds such as methyl red (MR) and nitro compounds such as 7-nitrocoumarin-3-carboxylic acid (7NCCA). The aim of this study was to clarify the specificity of the major E. coli reductases. METHODS AND RESULTS Enzymatic assays with pure enzymes obtained after cloning, overproduction and purification under native or denaturing conditions were performed on three enzymes: AzoR, NfsA and NfsB. Their dependence on putative cofactors such as flavin mononucleotide (FMN), NADH and NADPH was studied as well as the reductase capacity of E. coli mutants depleted for one, two or three of the corresponding genes. CONCLUSIONS AzoR was able to reduce both MR and 7NCCA, whereas NfsA and NfsB could only reduce the nitro compound. AzoR and NfsB were strictly FMN dependent in contrast to NfsA. At a low oxygen concentration, the three proteins were not mandatory for azo reduction and nitro reduction, but in optimal aerobic conditions, azoR was essential for MR reduction, and an nfsA/nfsB combination was important for 7NCCA reduction. Overexpression of azoR gene was able to compensate for the loss of nfsA and nfsB under aerobic conditions. SIGNIFICANCE AND IMPACT OF STUDY These data provide new insights into the substrate specificity of major E. coli nitroreductases and demonstrate that oxygen is an important parameter to take into account in studies of nitroreductase activity.
