Abstract
This article analyzes how couples made up of two mothers redefine their roles when they break up as well as how legal professionals frame the custodial arrangements of these former same-sex couples. To do so, we focus on the case of Quebec, Canada, where parentage equality between mothers was attained as early as in 2002. We rely on individual semi-structured interviews with mothers' (N = 17) and legal professionals' accounts (N = 23) as well as on court records regarding physical custody arrangements. We find that the legal recognition of both mothers favors coparenting practices, and especially joint physical custody. However, the heteronormative frame of custody arrangements lingers. Sexual minority mothers struggle with the valorization of birth motherhood and with the standard of gendered parental complementarity. Indeed, professionals can still fall back on heteronormative norms, notably by assigning to non-birth mothers a "paternal" role. In the end, the inexperience of many professionals on LGBTQ+ issues, the embeddedness of heteronormativity in day-to-day relations, as well as the permanence of heteronormative legal categories and professional practices are all factors that set these families apart.

Abstract
RESEARCH QUESTION Insemination fraud occurs when the spermatozoa intended for insemination have been intentionally swapped for another person's without the knowledge of the intended family. In what ways is this experienced by recipient parents and their offspring? DESIGN This was a qualitative study involving semi-structured interviews with 15 participants (seven parents and eight donor-conceived individuals) affected by insemination fraud involving the same doctor in Canada. RESULTS This study documents how insemination fraud is experienced by recipient parents and (their) offspring at the personal and relational levels. At the personal level, insemination fraud can induce a sense of agency loss for the recipient parents and a (temporary) sense of identity realignment for the offspring. At the relational level, it can lead to a reshuffling of genetic ties through the new genetic mapping it involves. This reshuffling can, in turn, disrupt kinship ties, leaving a deep imprint that some families struggle to overcome. Experiences differ depending on whether or not the progenitor is known, and when he is known, on whether it is another donor or the doctor himself. CONCLUSIONS Given the significant challenges that insemination fraud poses to the families who experience it, it is important that this practice be subjected to the medical, legal and social scrutiny it deserves.

Abstract
Abstract
Background
Despite the importance of changing health behaviours in the context of preventing and managing non-communicable chronic diseases (NCD's), physician use of evidence-based behaviour change counselling (BCC) is low, and BCC skills competency is generally poor.
Motivational communication (MC) is a patient-centred, evidence-based BCC approach used by healthcare providers, designed to increase patient motivation to adopt a healthy lifestyle. MC-based approaches improved a range of health behaviours (smoking, diet, physical activity) in patients with NCDs, leading to increased demand for physician training. Despite the widespread dissemination of training programs, data on their efficacy in achieving competency among physicians is limited. This is likely due to a lack of consensus on the core communication competencies to be achieved, and in the absence of acceptable, valid and reliable tools to measure skill acquisition.
Results
Using an integrated knowledge translation (iKT) approach that engaged 199 international physicians, behaviour change experts and health administrators, we have identified 11 core evidence-based communication competencies that physicians should acquire in the context of NCD prevention/management. They have been incorporated into a basic 4 hr face-to-face MC training program called “LEARN THE BASICs”. To assess MC competency, we have also developed a reliable, engaging, efficient, 'user-friendly' case-based digital assessment tool called the MC-Competency Assessment Test (MC-CAT).
Conclusions
Strategies for optimizing and tailoring this program, including finding the most cost-effective training dose, the impact of supplemental training components (e.g., in person vs. digital coaching; booster sessions), and delivery modes (e.g., face-to-face vs digital/online), will be discussed in the context of optimizing implementation success.

Abstract
Abstract
Issue/problem
Poor health behaviours are at the centre of most non-communicable chronic diseases and account for a significant amount of morbidity and mortality. Healthcare professionals, and especially physicians, are in a unique position to be able to positively influence their patients and aid them in changing poor health behaviours. However, most physicians report having low confidence or a lack of skills to effectively achieve this.
Description of the problem
The main approach that physicians take to influence their patients’ poor health behaviours is to provide them with advice and evidence about the impact of the poor health behaviours. This strategy has been shown to have limited impact on changing patient behaviour. As such, there is a need to develop effective interventions that target changing physician health behaviour counselling behaviours, effectively, a behaviour change intervention for physicians so that they are better at helping patients change their behaviour.
Results
Using a structured stakeholder-oriented approach (the ORBIT model for developing behavioural interventions) we have systematically developed a robust behaviour change-based continuing medical education curriculum (leveraging motivational communication), and online assessment tool to improve physician competency. These were developed by a pan-Canadian team with notable international input through the IBTN.
Lessons
The use of a structured stakeholder-driven process, we have developed an intervention which seems to have greater relevancy to the target audience, lead to greater engagement, and a higher probability of implementation than a researcher led approach. Whilst the studies are still ongoing, it is anticipated that this intervention will be able to dramatically improve the health of individuals through effective health behaviour change interventions by healthcare professionals.

Abstract
Cet article présente les résultats de recherche visant à mieux comprendre le point de vue et l’expérience d’hommes agissant à titre de donneurs de sperme dans la concrétisation de projets parentaux d’autrui. Notre démonstration s’appuie sur des données qualitatives tirées de deux corpus d’entrevues réalisées auprès d’hommes ayant offert leur sperme à des couples lesbiens, soit dans le cadre d’un rapport relationnel préexistant avec les femmes (n = 10), ou d’une entente établie à partir d’un contact sur Internet (n = 8). Les résultats plaident pour une conception plus nuancée de leur participation au projet parental d’autrui. Non seulement la conviction de poser un geste altruiste pour les couples lesbiens est perçue par ces hommes comme une source importante d’accomplissement, mais la méthode de procréation préconisée s’inscrit dans une démarche consensuelle et transparente, à la rencontre des besoins des personnes impliquées et de leurs motivations respectives.

Abstract
Subjects with occupational asthma (OA) are often left with permanent sequelae after removal from exposure, and assessing their impairment/disability should utilise various tools. The aim of the present study was to examine whether: 1) assessment of inflammation in induced sputum is relevant to impairment; and 2) use of questionnaires on quality of life and psychological factors can be useful for the evaluation of disability. In total, 40 subjects were prospectively assessed for permanent impairment/disability due to OA 2 yrs after cessation of exposure. Impairment was assessed as follows: 1) need for asthma medication; 2) asthma severity; 3) airway calibre and responsiveness; and 4) degree of inflammation in induced sputum. Disability was assessed according to quality of life and psychological distress. There was a significant improvement in airway responsiveness and inflammation from diagnosis to the present assessment. Sputum eosinophils > or =2% and neutrophils >60% were present in eight (20%) and 12 (30%) out of all subjects, respectively, one or the other feature being the only abnormalities in 15% of subjects. Quality of life was moderately affected and there was a prevalence of depression and anxiety close to 50%. In the assessment of subjects with occupational asthma, information on airway inflammation and psychological impacts are relevant to the assessment of impairment/disability, although these findings need further investigation.

Abstract
In order to evaluate the possible consequences of temporal lobe epilepsy on reading acquisition, we first compared the reading skills and phonological awareness abilities in a set of 13-year-old identical twins, one of whom is affected by temporal lobe epilepsy (LB). We then compared their performances to those of an age- and IQ-matched control group. Both siblings have an intellectual quotient above average as well as normal memory and linguistic abilities. Results showed that the reading age of LB (assessed by the Lefabvrais French reading test) was more than two years behind expectations whereas that of her sister was above average. Further, in contrast to her sister and healthy control subjects, LB exhibited specific deficits in elaborate metaphonological awareness abilities (non-word repetition, rhyme production, phonemic segmentation and syllabic inversion). These could be linked to temporal lobe dysfunction, thus confirming the important role of the temporal lobes in reading acquisition.

Abstract
We compared visual evoked potentials and psychophysical reaction times to the onset of first- and second-order motion. The stimuli consisted of luminance-modulated (first-order) and contrast-modulated (second-order) 1 cpd vertical sine-wave gratings drifting rightward for 140 ms at a velocity of 6 degrees /s. For each condition, we analysed the latencies and peak-to-baseline amplitudes of the P1 and N2 peaks recorded at Oz. For first-order motion, both P1 and N2 peaks were present at low (3%) contrast (i.e., depth modulations) whereas for second-order motion they appeared only at higher (25%) contrasts. When the two types of motion were equated for visibility, responses were slower for second-order motion than for first-order motion: about 44 ms slower for P1 latencies, 53 ms slower for N2 latencies, and 76 ms slower for reaction times. The longer VEP latencies for second-order motion support models that postulate additional processing steps for the extraction of second-order motion. The slower reaction time to the onset of second-order motion suggests that the longer neurophysiological analysis translates into slower detection.

Abstract
In recent years, there has been a sustained interest in the so-called "frontal hypothesis" of schizophrenia: the idea that clinical symptoms and cognitive deficits characteristic of schizophrenia might be explained by defective function of the frontal lobes. Several studies have attempted to test this hypothesis by examining the performance of schizophrenic subjects on the Wisconsin Card Sorting Test (WCST), a neuropsychological evaluation widely believed to reflect the functional capacity of frontal lobes. A typical finding is that schizophrenic patients demonstrate a tendency to perseverate in producing an inappropriate response in spite of negative feedback. This perseverative tendency resembles the perseveration often seen in patients with frontal brain damage. This article proposes a critical examination of the available evidence linking frontal deficits with schizophrenia via the WCST. As we will show, in most of these studies, only a relatively small number of the available measures on the WCST are made, and consequently many interesting cognitive capacities in schizophrenic subjects have not been adequately examined with this test. These "non-classical" measures will be described and critically examined with respect to their pertinence for further work on schizophrenic subjects. Of particular interest are the "failure to maintain set", which measures cognitive instability, "conceptual responses", which can indicate a certain conceptual capacity even in subjects who show perseveration, and "learning to learn", which can demonstrate a capacity to profit from experience on the test. A second objective will be to critically examine the evidence concerning the capacity of schizophrenic patients to improve their performance on the WCST. To the extent that performance on the WCST reflects the functional level of cognitive capacities important for everyday life, any capacity in schizophrenic patients to improve their performance could have important implications for therapeutic intervention and re-education.

Abstract
OBJECTIVE To directly compare the performance of patients with schizophrenia and control subjects on the Wisconsin Card Sorting Test (WCST). Specifically, we sought to verify if there are significant differences on the "classical" WCST measurements (perseverative errors and number of categories), as well as on more rarely reported scores, and assess the extent to which patients with schizophrenia can improve their performance with card-by-card instructions and continuous verbal reinforcement. DESIGN Prospective cross-sectional study. SETTING Psychiatry department in a university-affiliated hospital. PARTICIPANTS 30 patients with schizophrenia, diagnosed according to DSM-IV criteria, and 30 control subjects, matched to patients according to age and education. INTERVENTION The WCST was administered according to the criteria of Heaton, and a subgroup of the patients with schizophrenia was given a retest after an explanation of the WCST and verbal reinforcements. RESULTS Patients with schizophrenia succeeded on fewer categories (t = 23.3, p < 0.001), committed more perseverative errors (t = 15.6, p < 0.001), made more perseverative responses (t = 14.6, p < 0.001), needed more trials to succeed at the first category (t = 9.2, p < 0.003) and gave significantly lower conceptual level responses (t = 14.1, p < 0.001) than the controls. However, on retest, patients with schizophrenia committed significantly fewer perseverative errors (t = 5.1, p < 0.001) and showed higher conceptual level responses (t = -3.45, p < 0.003). CONCLUSION Consistent with a hypothesis of frontal dysfunction in schizophrenia, patients with schizophrenia tend to show a perseverative deficit; however, some are able to partially overcome this deficit when given verbal reinforcement.

Abstract
OBJECTIVE To critically review existing literature examining the relationship between panic disorder (PD) and coronary artery disease (CAD). We specifically sought answers to the following questions: (1) What is the prevalence of PD in CAD patients? (2) What is the directionality of the relationship between PD and CAD? (3) What mechanisms may mediate the link between PD and CAD? METHODS Medline and Psychlit searches were conducted using the following search titles: "panic disorder and coronary artery disease", "panic disorder and coronary heart disease", and "panic disorder and cardiovascular disease" for the years 1980-1998. The above search was also repeated replacing "panic disorder" with "panic attacks" for the same period. RESULTS The prevalence of PD in both cardiology out-patients and patients with documented CAD ranges from 10% to 50%. The association between PD and CAD appeared strongest in patients with atypical chest pain or symptoms that could not be fully explained by coronary status. There is some evidence linking phobic anxiety but not PD per se to CAD risk, but little evidence linking CAD to PD risk. Studies of the mechanisms linking PD to CAD are still in their infancy, but there is preliminary evidence linking PD to reduced heart rate variability (HRV) and myocardial ischemia, two pathophysiological mechanisms related to CAD. CONCLUSION PD is prevalent in CAD patients, but it is unclear the extent to which PD confers risk for and/or exacerbates CAD. Prospective research is needed to more firmly establish PD as a distinct risk factor for the development and progression of CAD. However, because many of the symptoms of PD mimic those of CAD, differentiating these disorders and learning how they may influence each other is imperative for clinical practice.

Abstract
Although many studies have indicated information processing deficits in schizophrenic patients, the precise nature and underlying causes of these deficits remain largely uncertain. One prominent hypothesis is that these patients show insufficient attentional inhibition. This deficit to inhibition has been linked to certain cognitive disorders in schizophrenic patients, including attention deficits, as well as to some clinical symptoms, especially those involving delusional thought, hallucinations,and poor contact with reality. The hypothesis of deficient attentional inhibition, although attractive in some ways, is difficult to work with, because it is not easy to directly measure "attentional inhibition". Several studies involving normal subjects have linked attentional inhibition with performance on a task demanding the suppression of distracting information: the presumption is that efficient attentional inhibition will permit rapid responses because the distracting information will be quickly suppressed, allowing undistracted processing of the target information. The present study measures schizophrenic patients' performance on a task demanding suppression of rapidly-presented visual information. An important methodological feature of this study is that performance is measured in terms of "percent correct responses" rather than the reaction time measures typically used in tasks demanding distractor suppression, such as Stroop-like selective attention tasks. Since reaction times are not considered, the results cannot be interpreted in terms of deficient response organization and execution. Schizophrenic (18) and normal (18) subjects underwent trials in which a visual target was the second of two stimuli presented in rapid succession. Interference produced by a non-target significantly impaired perception of the target for schizophrenic patients. This effect persisted longer in the schizophrenic subjects possibly because of deficient attentional inhibition.

Abstract
We have prepared an atlas of the human cerebellum using high-resolution magnetic resonance-derived images warped into the proportional stereotaxic space of Talairach and Tournoux. Software that permits simultaneous visualization of the three cardinal planes facilitated the identification of the cerebellar fissures and lobules. A revised version of the Larsell nomenclature facilitated a simple description of the cerebellum. This atlas derived from a single individual was instrumental in addressing longstanding debates about the gross morphologic organization of the cerebellum. It may serve as the template for more precise identification of cerebellar topography in functional imaging studies in normals, for investigating clinical-pathologic correlations in patients, and for the development of future probabilistic maps of the human cerebellum.

Abstract
OBJECTIVE Previous studies have reported poorer health behaviors in high vs. low hostile subjects. The role of stress in these observed differences has not been explored although interpersonal stress does increase cardiovascular response in high hostiles. Given evidence that stress may induce increased salt-intake, this study examined the role of hostility and interpersonal stress in increasing sodium consumption in addition to cardiovascular reactivity. METHOD Sixty-nine male undergraduates were categorized into high (HiHo) and low hostile (LoHo) groups based on Buss-Durkee Hostility Inventory scores. Subjects engaged in either a math task with harassment, math task without harassment, or a control/rest condition. Sodium intake was assessed posttask by having subjects ingest a sodium-free soup that was presented with a saltshaker without any comments. Cardiovascular measures were also recorded. RESULTS HiHo subjects consumed more salt than LoHo subjects irrespective of experimental condition. HiHo subjects who were harassed also exhibited greater cardiac output, systolic blood pressure, and forearm blood flow than did HiHo nonharassed, HiHo control, or LoHo subjects. CONCLUSION HiHo subjects exhibited increased salt-intake, although evidence for stress-induced salt-intake was not obtained. Nonetheless, the combination of salt and stress may contribute to the cardiovascular hyperreactivity and risk for cardiovascular disease in hostile individuals.
