Abstract
BACKGROUND In France, many people consult "bonesetters" for several medical reasons. Little is known about them. We aimed to investigate the practices of traditional healers in France as well as their profile and that of their customers. METHODS This was a survey carried out in Metropolitan France. A 33-item questionnaire developed by a multidisciplinary group was sent to a sample of 148 traditional healers found on the Internet and by word of mouth. RESULTS Of the 148 questionnaires sent, 89 (60.1 %) were returned and 67 (45.3 %) were analyzed: 51.5 % (n = 34) of respondents were men, and the mean (±standard deviation) age was 51.6 ± 11.6 years. The respondents considered that they had received a gift of healing and were mainly magnetic healers (68.2 %). They became aware of this gift at a mean age of 19.9 ± 14.1 years. The traditional healers practiced mainly in rural areas (54.5 %), at home (59.1 %), and used their hands to transmit energy (95.5 %). They advertised their practice mainly by word of mouth (89.4 %) and had a predominantly female clientele (78.1 %). Various diseases were treated, with the most frequent being subjective complaints (pain, stress, fatigue, insomnia) and dermatological complaints (eczema, accidental and post-herpes-zoster burns, psoriasis, and warts). Most respondents considered their activities to be complementary to conventional medicine, and 10.9 % considered them more effective. Some indicated that they did not consider themselves "healers" but rather "providers of relief". DISCUSSION The results of this survey provide a better understanding of this network of local care that revolves around medicine.

Topical sirolimus solution for lingual microcystic lymphatic malformations in children and adults (TOPGUN): study protocol for a multicenter, randomized, assessor-blinded, controlled, stepped-wedge clinical trial.

Abstract
Background Lingual microcystic lymphatic malformations (LMLMs) are rare congenital vascular malformations presenting as clusters of cysts filled with lymph fluid or blood. Even small well-limited lesions can be responsible for a heavy burden, inducing pain, aesthetic prejudice, or oozing, bleeding, infections. The natural history of LMLMs is progressive worsening punctuated by acute flares. Therapeutic options include surgery, laser excision, and radiofrequency ablation but all are potentially detrimental and expose to local relapse. Therefore, the management frequently relies on a “watchful waiting” approach. In complicated LMLMs, treatment with oral sirolimus, a mammalian target of rapamycin (mTOR) inhibitor, is often used. Topical applications of sirolimus on the buccal mucosae have been reported in other oral diseases with good tolerance and none to slight detectable blood sirolimus concentrations. We aim to evaluate the efficacy and safety of a 1 mg/mL sirolimus solution applied once daily on LMLM of any stage in children and adults after 4, 8, 12, 16, 20, and 24 weeks of treatment compared to usual care (no treatment). Methods This is a randomized, multicentric study using an individually randomized stepped-wedge design over 24 weeks to evaluate topical application of a 1 mg/mL sirolimus solution once daily, on LMLM, versus usual care (no treatment), the control condition. Participants begin with an observational period and later switch to the intervention at a randomized time (week 0, 4, 8, or 12). Visits occur every 4 weeks, either in the study center or by teleconsulting. The primary outcome will be the evaluation of global severity of the LMLM on monthly standardized photographs by 3 independent blinded experts using the physical global assessment (PGA) 0 to 5 scale. Secondary outcomes will include lesion size measurement and quality of life assessment, investigator, and patient-assessed global disease and specific symptoms (oozing, bleeding, sialorrhea, eating impairment, taste modification, aesthetic impairment, pain, and global discomfort) assessment. A biological monitoring will be performed including residual blood sirolimus concentration and usual laboratory parameters. Discussion Given the disappointing state of current treatment options in LMLMs, topical sirolimus could become firstline therapy in treating LMLMs if its efficacy and safety were to be demonstrated.

Abstract
OBJECTIVE To investigate the effects and duration of orally administered prednisolone on renal function evaluated by glomerular filtration rate (GFR) determination and creatinine (Cr) and symmetric dimethylarginine (SDMA) concentrations as well as on urinalysis, electrolytes, and hydric status in healthy dogs. ANIMALS 14 healthy Beagles. PROCEDURES In this prospective double-masked placebo-controlled study, dogs were randomized after baseline evaluation to receive a 7-day course of either prednisolone (1.5 to 2.0 mg/kg, PO, q 12 h) or a placebo. A repeated-measure design was performed, each dog participating in 4 successive sampling sessions. Clinical data, systolic blood pressure, CBC, and biochemical analyses including serum SDMA concentration, GFR determination, urine output quantification, and complete urinalysis were performed for all dogs the day before (D0) and at the end of steroid administration (D7) as well as 2 weeks (D21) and 4 weeks (D35) after the end of treatment. RESULTS At D7, when compared with baseline, GFR increased significantly in treated dogs, whereas creatinine and SDMA concentrations decreased significantly. GFR and Cr but not SDMA modifications persisted significantly at D21. None of the variables differed significantly from baseline at D35. The OR of presenting an albumin band on urine electrophoresis was 2.4 times as high in treated versus control dogs (OR, 36; 95% CI, 1.8 to 719.4; P = 0.02). CLINICAL RELEVANCE A short-term course of immune-suppressive prednisolone treatment in healthy dogs leads to a sustained but reversible renal hyperfiltration state. Modification in electrolytic variables can affect the clinical interpretation of blood work in such patients.

Abstract
INTRODUCTION This study aims to compare the vulnerability hypothesis and the expression hypothesis to explain a greater level of psychological distress among working women than among working men. METHOD The two hypotheses were contrasted by integrating work stressors, family stressors, work-family conflicts and psychosocial resources. The conceptual models were tested by using multilevel path analyses on 2026 employees in Quebec (Canada) based in 63 work establishments. RESULTS Results partially supported both hypotheses. According to the vulnerability hypothesis, single parenting, child-related problems and self-esteem were indirectly involved in the variation of psychological distress among women through family-to-work, otherwise known as work-family conflict. According to the expression hypothesis, although family-to-work conflict was closely associated with more psychological distress among women, this stressor was also closely associated with higher at-risk alcohol consumption among men. Couple-related problems and a sense of control likewise played a role in the expression mechanism through family-to-work conflict. CONCLUSION These results underline the importance of considering that gender contributes to mental health inequalities through multiple mechanisms. They also call for a distinction between the two directions of work-family conflict as gendered mediators.

Abstract
BACKGROUND The purpose of this research is to determine whether, in the Canadian workforce, cultural identity traits, particularly ethnicity and immigrant status, might modify the association of work with depressive symptoms. METHOD Data were derived from the nine cycles of the National Population Health Survey (NPHS) conducted by Statistics Canada. Based on a sample of 6477 workers, multilevel regression models were brought into being. Analyses were adjusted for family-related factors, non-work social support, and personal characteristics. RESULTS After accounting for potential confounders, ethnicity and work-related factors were distinctly and directly associated with depressive symptoms. Workers belonging to visible minorities had significantly fewer depressive symptoms than their Caucasian counterparts. Unlike Caucasians, they were more often overqualified, less in a position to use their skills, and largely without decision-making authority. On the other hand, all analyses having to do with immigrant status led to inconclusive results. CONCLUSION Ethnicity seems to have some bearing on the association of work with depressive symptoms among members of the Canadian workforce. It might be beneficial to carry out targeted interventions aimed at improving working conditions according to ethnicity and situations involving professional overqualification.

Abstract
Une étude prospective, contrôlée et randomisée a été réalisée sur 320 suicidants ayant regagné leur domicile après passage au SAU de Bicêtre. Elle a comparé le protocole de prise en charge habituel (groupe G1) au protocole « OSTA » (G2). Celui-ci comporte trois appels téléphoniques au patient (à j8–j15, M1 et M3) 2,3, un appel téléphonique au professionnel référent (M3) et la mise à disposition d’un numéro d’appel téléphonique pour le patient et son référent. Une évaluation téléphonique finale à un an (M12) a été effectuée dans les deux groupes.Résultats:– le taux d’adhésion aux rappels téléphonique est important. Un contact téléphonique a été établi dans 85,5 % des cas à j8–j15, 80,9 % des cas à M1 et 72,4 % des cas à j8–j15 et à M1 ;– le taux de récidive suicidaire à un an ne diffère significativement pas entre G1 et G2 : 14,5 % vs 14,0 % (analyse en « intention de traiter »), 14,5 % vs 11,5 % (analyse « per protocole ») ;– l’initiation d’un suivi ambulatoire (ISA), au plus tard dans le mois suivant le mois de la TS, ne diffère également pas entre les deux groupes : 31,0 % (G1) vs 24,2 % (G2) ;– il existe une forte perte d’information lors du recueil à M12.Dans le groupe G2, la prise en compte de l’ensemble des données collectées à j8–j15, M1, M3 et M12, montre un taux de récidive suicidaire de 19,4 % (vs 14,0 % selon les seules données M12), mais aussi un taux d’ISA de 70,6 % (vs 24,2 %).Discussion et conclusionCes résultats sont confrontés aux données récentes de la littérature [1]. La discussion porte sur la méthodologie la plus appropriée à l’évaluation des effets de la veille sanitaire et aux moyens de contrôler les effets de l’évaluation sur les variables étudiées.

Abstract
For medical diagnostics and anti-doping analyses, insulin-like growth factor 1 (IGF-1) can be measured in serum using automated chemiluminescent immunoassays. The aim of this study was to assess the feasibility of using dried blood instead of serum to measure IGF-1 concentrations with an automated IGF-1 immunoassay and to evaluate if IGF-1 concentrations from dried capillary blood and serum were comparable. Blood samples (venous blood and capillary blood obtained from the arm skin using a device from Seventh Sense Biosystem) were collected with 20 μL Volumetric Absorptive Micro samplers (VAMS) (Mitra®, Neoteryx). These samplers offer the possibility of collecting a fixed volume of blood without perturbation by hematocrit. Starting from dried blood, an aqueous desorption in 0.9% NaCl was efficient to release IGF-1. The solution was directly analyzed on the automated IGF-1 immunoassay. IGF-1 concentrations after extraction from VAMS were lower than in serum (due to the dilution performed for the elution of IGF-1) but measurable for serum concentrations over 50 ng/mL. In addition, IGF-1 on VAMS was stable for at least one month at room temperature. Following adjustment for dilution, serum and dried blood IGF-1 concentrations were of the same order. However lower concentrations were obtained from the capillary blood in particular for high serum concentrations. In conclusion, a micro volume of dried capillary blood could be used to quantify IGF-1 with an automated chemiluminescent immunoassay. However, more data are needed to establish specific IGF-1 reference concentrations using dried capillary blood instead of serum.

Abstract
Background Despite mounting evidence on the association between work stress and burnout, there is limited knowledge about the extent to which workers' age and gender are associated with burnout. Aims To evaluate the relationship between age, gender and their interaction with burnout in a sample of Canadian workers. Methods Data were collected in 2009-12 from a sample of 2073 Canadian workers from 63 workplaces in the province of Quebec. Data were analysed with multilevel regression models to test for linear and non-linear relationships between age and burnout. Analyses adjusted for marital status, parental status, educational level and number of working hours were conducted on the total sample and stratified by gender. Results Data were collected from a sample of 2073 Canadian workers (response rate 73%). Age followed a non-linear relationship with emotional exhaustion and total burnout, while it was linearly related to cynicism and reduced professional efficacy. Burnout level reduced with increasing age in men, but the association was bimodal in women, with women aged between 20-35 and over 55 years showing the highest burnout level. Conclusions These results suggest that burnout symptoms varied greatly according to different life stages of working men and women. Younger men, and women aged between 20-35 and 55 years and over are particularly susceptible and should be targeted for programmes to reduce risk of burnout.

Abstract
New therapeutic proteins that trap circulating members of the transforming growth factor (TGF) beta superfamily (activins and growth differentiation factors) show promising effects on erythropoiesis and muscular growth. They are dimeric recombinant fusion proteins composed of the extracellular domain of a human activin receptor (ActRIIA or IIB) linked to the Fc part of human IgG1. Sotatercept (ActRIIA-Fc) and Luspatercept (a modified ActRIIB-Fc) in particular are now in phase 2/3 of clinical trials against anemia and included in the prohibited list established by the World Anti-Doping Agency. To prevent a potential misuse by athletes in the near future, a robust and sensitive method of detection is needed. We validated an approach adapted from an electrophoretic method used for the detection of recombinant erythropoietins that allowed detection of various ActRIIA-Fc and ActRIIB-Fc proteins, including variants produced in different cell types, after a single immuno-extraction step. After separation by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), an initial testing procedure performed by single-blotting can indicate the presence of an ActRII-Fc (indifferently type IIA or IIB). A confirmation performed by double-blotting using different antibodies for detection allows a more precise identification of the type of ActRII-Fc (IIA, IIB). Starting from a few hundred microliters of serum or plasma, this method is specific, sensitive, and easy to perform. It could easily be adopted by anti-doping laboratories.

Abstract
Manipulation of blood and blood components is prohibited in sports by the World Anti-Doping Agency (WADA). This includes the use of blood substitutes to increase oxygen transport, like haemoglobin-based oxygen carriers (HBOCs), which are compounds derived from haemoglobin. Despite their medical interest, the first generation of HBOCs had serious adverse effects and was abandoned. However, new studies are now exploiting the properties of marine worm haemoglobins, which circulate as giant extracellular complexes with high oxygen-binding capacities. HEMOXYCarrier® (HC), developed by Hemarina, is one of the most advanced and promising HBOCs, and HC may become a tempting doping tool for athletes in the future. Here, HC detection in plasma/serum was evaluated with the method used to detect the first HBOCs, based on electrophoresis and heme peroxidase properties. An HC-derived product was identified in human plasma up to 72 h after in vitro incubation at 37 °C. HC degradation also induced methemalbumin formation. After injecting HC at the effective dose of 200 mg/kg into mice, the HC-derived product was detected only for a few hours and no accumulation of methemalbumin was observed. Due to this limited detection window in vivo, measuring specific worm globin degradation products by mass spectrometry might be an alternative for future anti-doping analyses.

Abstract
Stabilizing the labile factor HIF (hypoxia inducible factor) for therapeutic use has led to the development of various molecules by pharmaceutical companies. These HIF stabilizers show promising erythropoiesis stimulating capacities and are of great interest for patients with chronical kidney disease and anemia. Amongst them FG-4592 from FibroGen is now under phase 3 of clinical studies. While this drug is still under investigation, a parallel market already allows to buy this product, which could be tempting for some athletes willing to increase their performances. To avoid such a use for doping purpose, WADA has listed HIF stabilizers and FG-4592 in particular as prohibited substances since 2011 and some anti-doping laboratories have developed a technique of identification of FG-4592 in urine. Here, we described the first case ever identified by an anti-doping laboratory of an athlete using FG-4592. Detection and confirmation in urinary samples was performed by LC-MS/MS. In addition, potential indirect markers erythropoietin (EPO) and hematological parameters followed in the Athlete Biological Passport (ABP) were analyzed during and after the period of use but showed no profound alterations. Only ABPS (abnormal blood profile score) reached (but did not exceed) the upper limit proposed by the ABP adaptive model just after the period of use of FG-4592. Altogether this case sends a warning for anti-doping laboratories which now must strengthen surveillance on HIF stabilizers and develop sensitive methods of detection for this new class of drugs.

Abstract
Targeting diseased cells is a challenging issue in both pharmacological and biological therapeutics. Gene therapy is emerging as a novel approach for treating rare diseases and for illnesses for which there is no other alternative. An important limitation of gene therapy has been the off-target effects and therefore efforts have been focused on increasing the specificity of gene transfer to the targeted organ. Here, we describe a promoter containing six nuclear factor of activated T cells (NFAT) consensus sequences, which is as efficient as the cytomegalovirus (CMV) promoter to drive expression in vascular smooth muscle cells both in vitro and in vivo. In contrast to the CMV promoter it is activated in a Ca(2+)-dependent manner after endoplasmic reticulum depletion and allows the transgene expression only in proliferative/diseased cells. Overexpression of sarco/endoplasmic reticulum (SR/ER) Ca(2+) ATPase 2a under the control of this NFAT promoter inhibits restenosis after angioplasty in rats. In conclusion, this promoter may be useful for gene therapy in vascular proliferative diseases and other diseases involving upregulation of the NFAT pathway.

Abstract
A collection of various Staphylococci was screened for their anti-Legionella activity. Nine of the tested strains were found to secrete anti-Legionella compounds. The culture supernatants of the strains, described in the literature to produce hemolytic peptides, were successfully submitted to a two step purification process. All the purified compounds, except one, corresponded to previously described hemolytic peptides and were not known for their anti-Legionella activity. By comparison of the minimal inhibitory concentrations, minimal permeabilization concentrations, decrease in the number of cultivable bacteria, hemolytic activity and selectivity, the purified peptides could be separated in two groups. First group, with warnericin RK as a leader, corresponds to the more hemolytic and bactericidal peptides. The peptides of the second group, represented by the PSMα from Staphylococcus epidermidis, appeared bacteriostatic and poorly hemolytic.

Abstract
The current qualitative research studied representations of illness posttreatment from a heart transplant group, a panic disorder group, and a tic disorder group. All three groups were preoccupied with perceptions about the impact of the illness, perception of self and the perception of how others view the ill person. The heart transplant group seem to adopt an active style of coping compared to the panic disorder group who presented a more passive, anticipatory mode of coping, and the tic group who were preoccupied with control over the perceptions of others. This qualitative information could help optimize adaptation strategies.

Abstract
The efficacy of cognitive-behavioral therapy (CBT) is clearly demonstrated in the treatment of panic-disorder with agoraphobia (PDA). Between 70% and 90% of people with PDA obtain an higher global functioning level after CBT, yet symptoms remain in 10 to 30% of participants after treatment termination. The goal of the present study is to find which variables have an effect on different CBT modalities (individual, group, self-help) for persons with moderate and high PDA. Eighty-four persons were randomly assigned to one of three treatment modalities. Evaluations were made before treatment, immediately after and one year later. Results show that sex, number of years with agoraphobia and anxiety level significantly predict outcome at post-test for the individual modality. However, only the number of years with agoraphobia is a strong predictor one year later for this treatment modality. For the self-help modality, no predictor is significant neither at post-test nor one year later. For the group modality, the agoraphobic avoidance predicts outcome at post-test whereas symptoms severity predicts outcome one year later.

Abstract
Dopamine release within the nucleus accumbens shell is suggested to control the salience of environmental stimuli, and previous research has shown that the indirect dopamine agonist D-amphetamine can alter the salience of both aversive and neutral stimuli. In experiment 1, the effect of systemic injection of D-amphetamine (0.5, 1 mg/kg) on fear conditioning to a tone was assessed in an 'off-baseline' conditioned suppression procedure using several footshock intensities. Although the effects of amphetamine on conditioning were unclear, the results indicated a deficit of simple tone habituation in amphetamine-treated rats. In experiment 2, habituation of the orienting reaction to a tone was assessed by the progressive reduction of lick suppression upon repeated presentation of the auditory stimulus. D-Amphetamine delayed tone habituation, whether administered systemically (0.5, 1 mg/kg) or into the nucleus accumbens shell (3, 10 microg/0.5 microl). These data are consistent with electrophysiological and neurochemical data demonstrating the role of nucleus accumbens dopamine in novelty processing. The relevance of the data to latent inhibition is discussed.

Abstract
Recent epidemiological studies have revealed a possible correlation between exposure to high levels of dioxins or dioxin-like compounds and diabetes. Yet the interaction between insulin and dioxin actions remains elusive. We studied the regulation of insulin-like growth factor binding protein-1 (IGFBP-1), a protein involved in glucose homeostasis and whose expression is down-regulated by insulin. We showed that 2,3,7,8-tetrachorodibenzo-p-dioxin (TCDD) specifically induced IGFBP-1 mRNA in human hepatocytes and HepG2 human hepatoma cells (2.5- and 8-fold, respectively). Cellular and secreted IGFBP-1 protein levels were also up-regulated. Transfection and reporter assays showed that the IGFBP-1 promoter was activated by TCDD and that this activation was dependent on the integrity of a proximal xenobiotic-responsive element (XRE). This XRE, located near the insulin-glucocorticoid regulatory region, binds the aryl-hydrocarbon receptor. In agreement with previous studies, the IGFBP-1 promoter was down-regulated by insulin (50%); we show here that although TCDD activated the IGFBP-1 promoter 5- to 6-fold, the combination of TCDD and insulin led to an expression level of IGFBP-1 that was higher than basal level (2- to 3-fold activation). Similar regulations were observed for the endogenous IGFBP-1 mRNA. These data suggest that the xenobiotic-hormonal regulatory region of the IGFBP-1 promoter mediates an up-regulation of IGFBP-1 expression by TCDD even in the presence of insulin. Because IGFBP-1 modulates blood glucose levels, the up-regulation of IGFBP-1 by dioxins might account for the disruptive effects of these pollutants on glucose metabolism.

Abstract
The dioxin 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD) induces phase I and II xenobiotic metabolizing enzymes (XME) which act sequentially to eliminate different classes of xenobiotics. The transcriptional effects of TCDD are generally mediated by the arylhydrocarbon receptor (AhR). We hypothesized that TCDD could also act indirectly, by increasing the activity of cytochrome P450 1A1 (CYP1A1), a phase I gene, which could then mediate the induction of other XME genes, such as the NAD(P)H:quinone oxidoreductase 1 (NQO1). To test this hypothesis, NQO1 gene expression was monitored after either overexpression of CYP1A1 or siRNA-mediated knock-down of CYP1A1 activity in the hepatoma cell line HepG2. Overexpression of CYP1A1 in the absence of TCDD was carried out using either adenoviral infection or the "Tet-off" system. Recombinant adenoviruses were produced encoding no protein, CYP1A1 (Ad1A1), or a mutated inactive CYP1A1 (Ad1A1mut). In the HepG2 Tet-off cell line, CYP1A1 expression was induced by the removal of doxycycline (dox) from the cell medium. Ad1A1 infection or dox removal induced CYP1A1 activity and H(2)O(2) production similarly to TCDD treatment. Moreover, in both systems, the amount of NQO1 mRNA increased to the same level as after TCDD treatment (approximately 2-fold). The UDP-glucuronosyl transferase 1A6 (UGT1A6) gene is also similarly regulated. NQO1 gene expression was not induced when mutant, inactive CYP1A1 was overexpressed or when the antioxidant N-acetyl cysteine (NAC) was added to Ad1A1. Finally, either NAC or siRNA directed against CYP1A1 mRNA decreased the induction of NQO1 gene expression by TCDD. We conclude that, after exposure to TCDD, the NQO1 gene expression can be controlled by CYP1A1 activity through an oxidative stress mediated pathway.

Abstract
In an effort to further improve the hybridisation potential of anhydro-hexitol nucleoside analogues, the 1'-methoxyl and 3'-methoxyl substituents were introduced and evaluated for their antisense potential. In view of the selectivity of pairing with RNA, especially the introduction of a 3'-O-alkyl moiety deserves further study.
