Propositions de réflexion à partir de l’article de Cyril Desjeux sur les modalités de coopération entre personnes valides et handicapées. Commentaire.

In this short article, we provide a commentary on Cyril Desjeux’ article (“Care” made for disabled persons: What are the ethical and power issues?). We return here to several questions raised by his article. The first concerns the various ways of qualifying an act as “help”, “care” or “cure”, the tensions that can result from this process, and the issues raised by these qualifications for the actors. In particular, we insist on the relationship between this process of qualification and professional issues, as it can challenge the boundary between medical and non-medical professions. Secondly, we situate the debates addressed by Cyril Desjeux in recent developments concerning the status of sick and disabled people, the promotion of their autonomy and their participation in decisions that concern them. We draw the reader's attention to the unexpected and potential negative effects of the willingness to involve disabled people, when this will turns into a normative directive. Finally, we emphasize the originality of Cyril Desjeux’ article in Alter journal. It presents “research-in-action” that goes beyond the strict academic framework.

Evidence-making hepatitis C cure: Towards a science that knows more carefully

There has been some controversy concerning the curative potential of new treatments for hepatitis C. This follows a systematic review of the Cochrane Collaboration questioning the clinical benefits of direct-acting antivirals (DAAs). This controversy has been debated as a matter of methods regarding how best to evidence treatment in an evidence-based medicine (EBM) approach. Drawing from science and technology studies (STS), we offer an alternative perspective. We propose a different way of thinking with evidence; one which treats ‘evidencing as performative’. Using the Cochrane review and its linked published responses as a resource for this analysis, we consider how hepatitis C cure is differently made-up through the knowledge-making practices performing it. We show how matters of apparent fact in evidence-based science are enacted as matters of clinical, social and ethico-political concern. We notice hepatitis C cure as a fluid object in negotiation. We highlight the limits of current debate to advocate a more critical and careful practice-based approach to knowing hepatitis C cure. This calls upon public health researchers to reflect on the performative work of their evidencing. We propose a ‘more-than’ EBM approach which treats ‘evidence-based’ science as an ‘evidence-making intervention’. We consider the implications of such an approach for the evidencing of public health interventions and for treating hepatitis C in the DAA era of ‘viral elimination’.

INFLUENCE OF POST-CURE TREATMENTS ON HARDNESS AND MARGINAL ADAPTATION OF COMPOSITE RESIN INLAY RESTORATIONS: AN IN VITRO STUDY

Objectives:

The purpose of this study was to evaluate the Vickers hardness number (VHN) and the in vitro marginal adaptation of inlay restorations of three hybrid composite resins (Filtek Z250, Opallis and Esthet-X) subjected to two post-cure treatments.

Material and Methods:

For the microhardness test, three different groups were prepared in accordance with the post-cure treatments: control group (only light cure for 40 s), autoclave group (light cure for 40 s + autoclave for 15 min at 130°C); and microwave group (light cure for 40 s + microwave for 3 min at 450 W). To assess the marginal adaptation, the composite resin was inserted incrementally into a mesial-occlusal-distal cavity brass mold and each increment light-cured for 40 s. A previous reading in micrometers was taken at the cervical wall, using a stereomicroscope magnifying glass equipped with a digital video camera and image-analysis software. Subsequently, the specimens were subjected to the post-cure treatments (autoclave and microwave) and a reading was taken again at the cervical wall. Data were compared using ANOVA for the hardness test, split-plot ANOVA for the adaptation assessment and Tukey''s test for multiple comparisons. A significance level of 5% was adopted for all analyses.

Results:

The post-cure treatments increased the hardness of conventional composites (p<0.001) and the gap values of inlay restorations (p<0.01). Filtek Z250 showed higher hardness (p<0.001) and lower gap values than Opallis and Esthet-X (p<0.05). Gap values did not exceed 90 μm for any of the experimental conditions.

Conclusion:

The post-cure treatments increased the VHN and the gap values on the cervical floor of composite resin inlays. Moreover, Filtek Z250 showed the best results, with higher hardness and lower gap values.     

A critical analysis of the degree of conversion of resin-based luting cements

Objective

This study analyzed the degree of conversion (DC%) of four resin-based cements (All Ceram, Enforce, Rely X ARC and Variolink II) activated by two modes (chemical and dual), and evaluated the decrease of DC% in the dual mode promoted by the interposition of a 2.0-mm-thick IPS Empress 2 disc.

Material and Methods

In the chemical activation, the resin-based cements were prepared by mixing equal amounts of base and catalyst pastes. In the dual activation, after mixing, the cements were light-activated at 650 mW/cm² for 40 s. In a third group, the cements were lightactivated through a 2.0-mm-thick IPS Empress 2 disc. The DC% was evaluated in a FT-IR spectrometer equipped with an attenuated total reflectance crystal (ATR). The data were analyzed by two-way ANOVA and Tukey''s HSD test.

Results

For all resin-based cements, the DC% was significantly higher with dual activation, followed by dual activation through IPS Empress 2, and chemical activation (p<0.05). Irrespective of the activation mode, Rely X presented the highest DC% (p<0.05). Chemically activated Variolink and All Ceram showed the worst results (p<0.05). The DC% decreased significantly when activation was performed through a 2.0-mm-thick IPS Empress 2 disc (p<0.05).

Conclusions

The results of the present study suggest that resin-based cements could present low DC% when the materials are dually activated through 2.0 mm of reinforced ceramic materials with translucency equal to or less than that of IPS-Empress 2.     

The effects of multidimensional exercise treatment on community-dwelling elderly Japanese women with stress, urge, and mixed urinary incontinence: a randomized controlled trial

Background

Urinary incontinence is one of the most prevalent health problems and a significant cause of disability and dependence in the elderly. Pelvic floor exercise is effective in reducing stress urinary incontinence, but few studies have investigated the effect of behavioral management on urge and mixed incontinence.

Objectives

To determine the effects of multidimensional exercise treatment on reducing urine leakage in elderly Japanese women with stress, urge, and mixed urinary incontinence.

Design

Randomized controlled, follow-up trial.

Settings

Urban community-based study.

Participants

127 community-dwelling women aged 70 and older with stress, urge, and mixed urinary incontinence were randomly assigned to the intervention (n = 63) or the control group (n = 64).

Methods

Urine leakage and fitness data were collected at baseline, and after the intervention and follow-up. The intervention group received a multidimensional exercise treatment twice a week for 3-month. After treatment, the participants were followed for 7-month.

Results

There were significant differences in changes of functional fitness and incontinence variables between the intervention and control groups. The intervention group showed urine leakage cure rates of 44.1% after treatment and 39.3% after follow-up (χ² = 21.96, p < 0.001); whereas, the control group showed no significant improvement. The multidimensional exercise treatment was significantly effective in decreasing all three types of urinary incontinence. However, the effects of the exercise treatment were greater on stress urinary incontinence than on urge or mixed urinary incontinence. At the 7-month follow-up, while cure rates of all three types of urinary incontinence were significantly maintained, a slight reversal was seen only in the urge and mixed urinary incontinence (χ² = 10.28, p = 0.008). According to the logistic regression model, urine leakage volume (adjusted odds ratio OR = 0.69, 95% confidence interval CI = 0.39–0.98), compliance (OR = 1.03, 95%CI = 1.01–1.16), and BMI reduction (OR = 0.67, 95%CI = 0.48–0.89) were significantly associated with the cure of urine leakage after intervention. The cure rate of urine leakage after the follow-up was significantly associated with compliance (OR = 1.13, 95%CI = 1.02–1.29) and BMI reduction (OR = 0.78, 95%CI = 0.60–0.96).

Conclusions

The intervention group showed higher urine leakage cure rates than control group. This result suggests that multidimensional exercise strategies may be effective for all three types of urinary incontinence. BMI reduction and compliance to the intervention was the consistent predictor for the effectiveness of the exercise treatment.     

The early preclinical and clinical development of ganaplacide (KAF156), a novel antimalarial compound

ABSTRACT

Introduction: Ganaplacide (previously known as KAF156) is a novel antimalarial compound part of the imidazolopiperazine family.

Areas covered: At the time of writing, a total of eight studies addressing its preclinical and clinical development have been published on this compound, which is currently in phase 2 of clinical development, alongside lumefantrine in a novel soluble formulation as combination partner. This review provides an overview and interpretation of the published pre-clinical and clinical data of this possible next-generation antimalarial drug.

Expert opinion: In the search for a ‘magic bullet’ in malaria therapy and prophylaxis facilitating single encounter radical cure and prophylaxis, ganaplacide demonstrates some promising properties toward this ultimate goal. The available data suggest that ganaplacide exerts multi-stage antimalarial activity, and that its pharmacokinetic profile potentially allows for a simplified dosing regimen compared to that of existing antimalarial drug combinations. The first in-patient results demonstrate promising single-dose antimalarial activity, and no serious in-human safety and tolerability concerns have been reported to date.     

Praziquantel treatment of school children from single and mixed infection foci of intestinal and urogenital schistosomiasis along the Senegal River Basin: monitoring treatment success and re-infection patterns

Following major water development schemes in the 1980s, schistosomiasis has become a serious parasitic disease of children living in the Senegal River Basin. Both urogenital (Schistosoma haematobium) and intestinal (Schistosoma mansoni) schistosomiasis can be highly prevalent in school-aged children, with many individuals infected with both parasites. In order to investigate the transmission and re-infection dynamics of both parasite species, single and mixed infection foci at three villages (Nder and Temeye; S. mansoni and S. haematobium foci and Guia; S. haematobium focus) were studied. In each focus infected children were identified and selected for a 12-month study involving two treatments with praziquantel (40 mg/kg) three weeks apart at the beginning of the study and again 6 months into the study. Urine and stool samples were examined for schistosome eggs before and at 6 weeks and 6 months after chemotherapy. Prevalence and intensity of infection were recorded for each child at each time point. Before treatment, in all three villages, the prevalence and intensity of infection was extremely high for both S. mansoni (79–100%) and S. haematobium (81–97%). With the first round of chemotherapy sufficient cure rates (CRs) of both species were achieved in all villages (38–96%) with high egg reduction rates (ERRs) (97–99%). The data show that high and rapid re-infection rates occur, especially for S. mansoni, within a six-month period following treatment. Re-infection must be highly linked to ecological and seasonal factors. The persistence of S. mansoni in Nder could raise concern as levels of infection intensity remain high (geometric mean intensity at baseline 653 epg changed to 705 epg at 12 months) after four rounds of chemotherapy. This phenomenon could be explained by extremely rapid re-infection dynamics or a sub-optimal efficacy of praziquantel against S. mansoni in this village. High intensities in mixed infections may influence disease epidemiology and control warranting further studies. The disease situation in the SRB must be monitored closely and new treatment regimes should be designed and implemented to control schistosomiasis in the school-age population.     

From the Treatment of a Compulsive Spitter: A Psychoanalytical Approach to Profound Disability

Every practicing psychotherapist will have ample experience of patients expressing rage and hatred during the course of a session. In virtually all cases, patients emit their fury in a verbal form. But what happens when an angry, traumatized patient lacks the capacity to spit out nasty words and, instead, spits saliva? While most adult psychotherapy patients have developed a well‐internalized ability to keep their bodily fluids contained inside their bodies (with the possible exception of tears), severely and profoundly learned disabled patients can drool, vomit, urinate, defecate, ejaculate, and spit in the midst of a psychotherapy session. In view of this little‐discussed, yet not infrequent, clinical phenomenon, how can a psychotherapist function when under attack from the patient and his or her actual bodily fluids? In order to explore this aspect of disability psychotherapy, the author will discuss an eight‐year treatment with a psychotic, brain‐damaged psychogeriatric patient who spat compulsively in an aggressive manner. The author will describe the way in which he endeavoured to use classical psychoanalytical approaches in order to create an environment of safety in which the patient could begin to experience greater mental containment as well as bodily containment, and eventually arrive at a state in which her spittle could be transformed into feelings and even rudimentary words.
