Objective:
Following a traumatic brain injury (TBI), the majority of patients report difficulties with prospective memory (PM). However, there is not always a significant relationship between subjective and objective PM measures. Several variables may influence the degree of severity of perceived difficulties, including the severity of the injury and psychoemotional status. The aim of this study was to determine whether the severity of the TBI and anxiety and depressive symptoms were related to objective and subjective difficulties of PM.
Participants and Methods:50 patients (mean age = 31,3 years old) with a TBI (20 mild and 30 moderate/severe) in the post-acute phase of recovery and 15 matched healthy control participants (mean age = 32,3 years old) were recruited. They completed inventories assessing the presence of anxiety (BAI) and depressive (BDI) symptoms and performed the Ecological test of prospective memory (TEMP), an objective measure of PM. The Comprehensive Assessment of PM (CAPM), a subjective measure of PM, was also filled out by participants and their relatives.
Results:In patients with moderate/severe TBI, significant correlations were found between the CAPM and the BDI (r =.601, p<.001) and the BAI (r =.507, p=.004). A negative correlation was also observed between the relatives’ CAPM scores and the performance of the patients on the TEMP (r= -.374, p=.042). In patients with mild TBI, there was only a strong significant correlation between the CAPM and the BAI scores (r =.574, p=.008). However, no other correlation was significant between this group of patients and their relatives. Additionally, results on the TEMP were not significantly correlated with the CAMP completed by healthy control participants or their relatives. A linear regression conducted in the group of participants with TBI showed that BAI and BDI scores are the only significant predictors of the results on the CAPM (31% of the variance), while TBI severity is the only significant predictor of the results on the TEMP (37% of the variance).
Conclusions:The perception of PM difficulties in patients with a TBI does not seem to be related to their objective performance. Anxiety and depressive symptoms appear to influence their perception more than their objective performance. As suggested by their relatives, a decrease in self-awareness could explain the lack of relationship between subjective PM difficulties of patients with moderate/severe TBI and their objective performance. On the other hand, TBI severity is more strongly related to objective performance on PM tests. These results highlight the importance of using different measures to accurately assess PM and the various factors influencing this construct.

Objective:
Semantic memory deficits have been reported in both Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI). However, the nature of this decline is still a matter of debate. The aim of this study was to explore the patterns of semantic memory impairment in aMCI by examining performance on naming tasks, and on tests assessing both general and specific semantic knowledge.
Participants and Methods:Participants were divided in two groups matched for age and education, one comprising 33 aMCI individuals and the other 39 healthy controls. Three experimental tests assessing naming and semantic knowledge of unique items of famous persons (FACE) and places (PLACE), logos recognition (LOGO: brands and pictograms), and non-unique entities (Boston Naming Test: BNT) were administered, and the performance of the two groups was compared.
Results:Lower scores were observed on all naming tests (PLACE, FACE, LOGO and BNT) in the aMCI group compared to controls. On the PLACE test, the general knowledge mean score (M=84.5, SD=12.9) was significantly higher than the specific knowledge mean score (M=54.2, SD=18.5) in aMCI participants (t(31)=11.9, p<.001), but not in controls (general: M=92.2, SD=11.1; specific: M=73.7, SD=15.8), and there was a significant Group X Type of knowledge interaction (F(1,1)=15.13, p <.001, n2 = 18). On the FACE test, in addition to significant group and condition (naming, semantic questions) main effects, a significant interaction was found (F(1,1)=7.19, p = .009, n2 = .09). On the LOGO task, controls were significantly better on brand items (M= 94.4, SD=10.5) than on pictograms (M=83.3, SD=12.2), while no significant difference was noted in aMCI (brands: M=81.5, SD=22.6; pictograms: M=77.5, SD=14.1). Lastly, on the BNT, aMCI participants benefited more from phonemic cues than controls (F(1,1)=16.56, p<.001, n2=19), suggesting a lexical access deficit, in addition to their semantic memory impairment.
Conclusions:This study adds to the growing evidence confirming the presence of semantic memory deficits in aMCI. Specific semantic knowledge seems to be more affected than general semantic knowledge, a finding reported in previous studies. Lexical access deficits, in addition to semantic decline, were also observed in the aMCI group. These results allow for a better understanding of the pattern of semantic memory deficits in the prodromal stage of AD and could potentially facilitate diagnosis of aMCI.

Ionising radiotherapy is a well-established, effective cancer treatment modality, whose efficacy has improved with the application of newer technological modalities. However, patient outcomes are governed and potentially limited by aspects of tumour biology that are associated with radioresistance. Patients also still endure treatment-associated toxicities owed to the action of ionising radiation in normoxic tissue adjacent to the tumour mass. Tumour hypoxia is recognised as a key component of the tumour microenvironment and is well established as leading to therapy resistance and poor prognosis. In this review, we outline the current understanding of hypoxia-mediated radiotherapy resistance, before exploring targeting tumour hypoxia for radiotherapy sensitisation to improve treatment outcomes and increase the therapeutic window. This includes increasing oxygen availability in solid tumours, the use of hypoxia-activated prodrugs, targeting of hypoxia-regulated or associated signalling pathways, as well as the use of high-LET radiotherapy modalities. Ultimately, targeting hypoxic radiobiology combined with precise radiotherapy delivery modalities and modelling should be associated with improvement to patient outcomes.

Stress associated with caring for a mentally ill spouse can adversely affect the health status of caregivers and their children. Adding to the stress of caregiving is the stigma often placed against spouses and children of people with mental illness. Contrary to mental illness, many physical disorders such as cancer may be less stigmatized (expect pulmonary cancer). In this study, we measured externalized and internalized stigma, as well as psychological (depressive symptoms and stressful life events) and physiological (basal salivary cortisol levels) markers of stress in 115 spouses and 154 children of parents suffering from major depressive disorder, cancer, or no illness (control group). The results show that spouses and children from families with parental depression present significantly more externalized stigma than spouses and children from families with parental cancer or no illness, although we find no group differences on internalized stigma. The analysis did not show a significant group difference either for spouses or their children on depressive symptomatology, although spouses from the parental depression group reported greater work/family stress. Finally, we found that although for both spouses children the awakening cortisol response was greater on weekdays than on weekend days, salivary cortisol levels did not differ between groups. Bayes factor calculated on the null result for cortisol levels was greater than 100, providing strong evidence for the null hypothesis H0. Altogether, these results suggest an impact of stigma toward mental health disorder on psychological markers of stress but no impact of stigma on physiological markers of stress. We suggest that these results may be due to the characteristics of the families who participated in the present study.

Context
The Ministry of Health in Québec requested the National Institute of Excellence in Health and Social Services to produce clinical and implementation recommendations for the prophylaxis, diagnosis, and treatment of Lyme disease.
Objectives(i) Describe the process of trialing different modalities of patient engagement as a means to integrate a diversity of patient perspectives and (ii) Describe the learning process of INESSS regarding the integration of the patient perspective.
MethodologyAll documents were analyzed, and a survey with all advisory committee members and semi-structured interviews with stakeholders were conducted. Each interview was transcribed verbatim and imported into QDA miner software for the purposes of analysis. Data analysis was carried out concurrently with data collection to allow for an iterative approach between data collection and analysis.
ResultsFive methods to integrate the perspectives of patients were used: (i) interviews with patients, (ii) inclusion of patient partners within the advisory committee, (iii) literature review, (iv) focus groups with one patient association, and (v) feedback from patient associations on recommendations intended for decision makers and other targeted stakeholders. The patient partners influenced decisions by sharing their experiential knowledge. The patient interviews and the literature review added an in-depth perspective on the disease and experience with the healthcare system. The patient association members shared their perspectives and helped disseminate the recommendation to sustain a practice change.
ConclusionThe combination of methods to collect and integrate patients’ knowledge and patient associations’ perspectives helped develop a comprehensive understanding of a controversial object of evaluation.

Background
Executive dysfunctions have been studied as a potential endophenotype associated with the genetic basis of autism. Given that recent findings from clinical and molecular genetic studies suggest that autism and obsessive-compulsive disorder (OCD) could share a common pattern of heritability, we assessed executive functions as a possible common cognitive endophenotype in unaffected family members of individuals with either autism or OCD.
MethodsFive tests assessing executive functions (Tower of London, verbal fluency, design fluency, trail making and association fluency) were proposed to 58 unaffected first-degree relatives (parents and siblings) of probands with autism and 64 unaffected first-degree relatives of OCD patients. Results were compared with those of 47 healthy controls matched for age, sex, and level of education.
ResultsIn the Tower of London test, both groups of unaffected relatives showed significantly lower scores and longer response times compared with controls. No differences were observed between autism and OCD relatives and healthy controls in the four other tasks (verbal fluency, design fluency, trail making test and association fluency).
ConclusionsOur findings show the existence of executive dysfunction in the unaffected first-degree relatives of probands with OCD, similar to those observed in the relatives of patients with autism. These results support and extend previous cognitive studies on probands indicating executive dysfunctions in autism and OCD. Planning and working memory processes could thus represent a common cognitive endophenotype in autism and OCD that could help in the identification of genes conferring vulnerability to these disorders.

Objective
Schizoaffective disorder could be considered as a form of schizophrenia, a form of bipolar disorder, an independent disorder or a disorder intermediate between bipolar disorder and schizophrenia, within a psychotic continuum. The study of cognitive deficits in subjects with those diagnoses could help differentiate between these possibilities.
MethodsWe compared cognitive performances of schizoaffective (SZAff) subjects with those of subjects with schizophrenia (SZ), bipolar disorder with psychotic symptoms (life-time) (BDP), bipolar disorder without life-time occurrence of psychotic symptoms (BD) and normal controls (NC). We used two tests of executive functions – the Wisconsin Card Sorting Test (WCST) and the Trail-making Test (TMT) – that are known to be impaired in those disorders.
ResultsThe number of perseverative errors on WCST was highest in SZ subjects and gradually decreased in SZAff, BDP and, finally in BD subjects. By contrast, SZ and SZAff subjects obtained similar scores in the TMT, as did BD and BDP patients.
ConclusionsThese results suggest that, for some deficits, there may be a continuum between SZ, SZAff and affective disorders, whereas SZAff patients most closely resemble SZ patients for other deficits. This implies that different conceptual views about schizoaffective disorder should be seen as complementary, rather than mutually exclusive.

Introduction
In a context of rapidly evolving technologies and growing evaluative challenges, the National Institute of Excellence in Health and Social Services (INESSS) is developing an institutional ethical framework making explicit and transparent the guiding principles and new modalities of process for health technology assessment for public coverage.
MethodsThis framework is co-built by the INESSS experts - drugs, social services, technology and health services and cross-cutting methodologies - through literature and practice reviews as well as a consultative process on key topics with external collaborators.
ResultsThe development process aims to: (i) identify the principles applicable to all the objects evaluated, (ii) define the evaluation strategies used to appropriately address evaluation challenges in the clinical, organizational, economic and societal dimensions, (iii) equip the scientific teams to successfully integrate diversified knowledge from the literature, stakeholders participation and medico-administrative data banks, and (iv) facilitate deliberation leading to evidence-informed recommendations. It is envisioned as a fully integrated process rooted in a reflexive multi-criteria approach supporting fair and reasonable decision. The presentation will focus on one of the key aspects of this framework, i.e., the development of principles for stakeholder participation based on a recent INESSS methodological forum on the topic, and the agile deployment of innovative processes and tools in various projects, including the patient partnership developed with a pioneering academic centre.
ConclusionsThis framework provides explicit, transparent and cross-cutting processes and a framework for continuous improvement. The goal is to promote stakeholder engagement and enable increasingly complex arbitration aimed at equity and social justice, in a context of rising costs and uncertainty, and focused on the creation of value for our fellow citizens.

Introduction
Health technology assessment (HTA) and the development of clinical practice guidelines (CPGs) support important health policy and clinical decisions. Conflicts of interest (COI) and conflicts of commitment (COC) can undermine the credibility and integrity of these processes, that of the actors involved, and, more alarmingly, the health of the population. Thus, management of COI and COC is critical. Although COI among experts participating in HTA and CPG development are increasingly discussed and managed, little is said about COCs and the possible COI and COC associated with patient participation. The aim of our study, which is part of the Institut national d'excellence en santé et services sociaux (INESSS) continuing improvement process for COI and COC management, was to identify best practices in this matter.
MethodsWe examined the COI and COC management policies of ten HTA and CPG organizations and performed a review of the relevant academic literature.
ResultsThree HTA and CPG organizations had norms regarding the management of patients’ COI and COC, whether they were representatives of patient associations or not. These norms addressed situations such as: when a patient represents a patients’ association; when a patients’ association or an individual patient has important (financial) ties with the pharmaceutical industry; or when an expert or one of his/her family members suffers from the disease related to the HTA or CPG. The declaration of a COI or COC should not necessarily lead to the individual's exclusion from the entire HTA or CPG development process, but it must lead to some evaluation and management. Patients appointed to share their perspectives are not considered to have COI or COC if their mandate is explicit.
ConclusionsThe COI and COC of all participants in HTA and CPG development should be managed fairly and transparently. Therefore, the management of COI and COC among patients participating in HTA or CPG development should be based on the same principles as those applied to clinical experts.

Introduction:
Decisions about which health and social services to include in the publicly funded services basket are complex. Several criteria need to be taken into account in decision-making (DM), as well as ethical, economic and organizational issues. Nowadays a global consensus supports the view that citizens’ values and preferences must guide DM. To elicit these values and concerns regarding publicly funded services, the Quebec Health and Welfare Commissioner recently conducted a vast public consultation on the population viewpoints. Parts of this consultation targeted criteria for DM, approaches to assess new or current services and perspectives on appropriateness of care.
Methods:Various consultation methods were used in complementary steps: a representative population survey (n=1850), six regional focus groups (n=62), a call for briefs (n=52) for groups that wished to share their views, consultation meetings (n=35) with diverse stakeholders and a call for personal accounts (n=2633). It also held five deliberation sessions (18 citizens and 9 experts) over the course of the project on major related issues.
Results:The need to ensure the appropriateness of covered services was one of the strongest themes emerging from the consultation. Citizens want that the appropriateness evaluation be carried out under certain conditions: transparently, in explicit DM processes, using criteria that are clear and adaptable according to the disease or problem. The whole evaluation process needs to be well documented, showing clearly the data used and rejected, so that they can understand the decision and see on what basis it is supported. Among the usual criteria for DM, those related to cost are less valued whereas others are considered incomplete.
Conclusions:Citizens have clear viewpoints and expectations regarding DM criteria and processes for resource allocation. Decision-makers must take them into account to ensure that the basket of insured services is representative of social values and preferences.

This pilot project aims to test and see the relevance of the direct observation method to collect data on the barriers and facilitators to attending public places by seniors with TBI. The study is based on the conceptual framework VADA WHO which focuses on the development of friendly built and technological environments for seniors. Three elderly people participated in the study, recruited from an ongoing project, The Citizen Intervention in Community Living (APIC), in the presence of their personalized attendant. The study shows the feasibility of the method in terms of its acceptability and resources mobilized. It shows its relevance to access additional data that would have been difficult to obtain using others methods (e.g., semi-structured interview), such as the identification of the strategies used by the participants to address the obstacles encountered (avoidance, travel planning, use of physical and preventative support of the personalized attendant).

Objective:
The induction of sedation at the end of life is a much debated practice and not very documented. The goal of this study was to explore the practice from both a clinical and ethical point of view.
Methods:Data were collected through semistructured interviews with 19 Quebec physicians working in palliative care.
Results:Doctors' first priority was their patients, not patients' families. Clinically, the therapeutic aim of sedation was strictly to relieve suffering on the part of the patient. Ethically, getting the patient's consent was imperative. The family's consent was only required in cases of incapacity. Generally, sedation and euthanasia were seen as two distinct practices.
Significance of the research:There are still very few guidelines regarding end-of-life sedation in Québec, and its normative framework is more implicit than explicit. It should be noted that most of the respondents regarded sedation and euthanasia as two distinct practices.

Like the lobsters, some terrestrial crabs and other crayfishes, the Australian red claw crayfish, Cherax quadricarinatus, elaborates in its stomach wall calcium storage structures called gastroliths. For understanding the cyclic elaboration and stabilization of these amorphous calcified structures, we studied the organic matrix (OM) of these paired biomineralizations. After decalcification with acetic acid, we analysed the proteinaceous components of an acetic acid-insoluble fraction by two-dimensional electrophoresis. Nine spots were digested by trpsin and the tryptic peptides were sequenced by nanoLC-nanoESI-MS/MS mass spectrometry. About 100 peptidic sequences were compared to sequences previously registered in the databases. Seven of the partially sequenced organic matrix polypeptides are probably new proteins. Another one corresponds to the previously sequenced protein, GAP65, from Cherax quadricarinatus and the last one, which migrates in electrophoresis at around 25 kDa, presents strong homology with the crustacyanin-A2 subunit of Homarus gammarus.

From an evolutionary viewpoint, the molluscan nacre constitutes a fascinating object. This microstructure appeared early, in the Lower Cambrian period, about 530 million years ago, and since then, has been kept unchanged until today. Nacre is restricted to the conchiferan mollusks, where it occurs in t least three main classes, bivalves, gastropods and cephalopods. The aim of the present study is to investigate whether all nacres are built from the same “macromolecular tools”, proteins of the nacre matrix. To this end, we studied three new nacre models, the freshwater bivalve Unio pictorum, the cephalopod Nautilus macromphalus, and the gastropod Haliotis asinina, to which we applied a combined biochemical and proteomic characterization of their respective nacre matrices. The results of our approach, that can be defined as “shellomics” (proteomics applied to shell proteins) shed a new light on the macroevolution of nacre matrix proteins and on the in vitro design of nacre-like biomaterials.

Background. Abnormal serotonergic neurotransmission has long been demonstrated in suicidal behavior. The dorsal and median raphe nuclei housing the main serotonergic cell bodies and the prefrontal cortex (PFC), particularly the ventral part innervated by the serotonergic system, have therefore been studied extensively in suicidal behavior research. However, only a few studies have described neuropsychological function impairment in suicidal patients. We investigated PFC-related neuropsychological function in patients with suicidal behavior, separating dorsolateral PFC (DLPFC)- and orbitofrontal cortex (OFC)-related functions.
Method. We compared 30 euthymic patients with suicidal behavior aged 18–65 years with 39 control subjects, for the following neuropsychological domains: global intellectual functioning, reward sensitivity, initiation, inhibition, and working memory. Patients and controls were compared by means of univariate and multivariate analyses, adjusting for age at interview, level of education and mood state at the time of evaluation. Trait impulsivity, measured with the Barratt Impulsivity Scale version 10 (BIS-10), was also included as a covariate in a subset of analyses.
Results. Multivariate comparisons demonstrated significant executive function deficits in patients with suicidal behavior. In particular, we observed impairment in visuospatial conceptualization (p<0·0001), spatial working memory (p=0·001), inhibition (Hayling B–A, p=0·04; go anticipations, p=0·01) and visual attention (or reading fluency) (p=0·002). Similar results were obtained following adjustment for motor impulsivity as a covariate, except for spatial working memory.
Conclusions. These deficits are consistent with prefrontal dysfunction in patients with suicidal behavior. Differentiation between DLPFC- and OFC-related neuropsychological functions showed no specific dysfunction of the orbitofrontal region in patients with suicidal behavior in our sample.
