    Abstract Purpose: To review the existing literature on mild stroke, its consequences for patients and families, and the effectiveness of rehabilitation services targeting mild stroke.
    Method: A systematic search was conducted on Ovid (EMBASE and MEDLINE, 1950-2008), PubMed, CINAHL, and Cochrane (to 4th quarter 2008). Articles had to be written in French or English. The term "mild stroke" was combined with a variety of key words. Titles, abstracts, and results sections were screened, and the sample had to be composed of not greater-than 50% mild stroke. Two reviewers were involved in the selection process to ensure the research was reproducible and that all the literature was screened properly.
    Results: Thirteen articles meeting inclusion and exclusion criteria were found. Mild stroke survivors may present impairments that do not interfere with basic activities of daily living but do affect performance of complex tasks. The consequences for families remain unknown. Home interventions were found to help patients maximize their functions and reduce stroke sequelae.
    Conclusion: The majority of mild stroke survivors are sent home without referral to rehabilitation services although they present deficits that, if not addressed, can lead to deconditioning and impede community reengagement. The impact of mild stroke on families needs to be studied.

    Abstract Objective: To document the gap between actual and desired ideal services for relatives post-stroke from three perspectives: relatives, stroke clients and health professionals.
    Methods: A two-phase qualitative design and consisting of in-depth interviews (Phase 1) and 3 focus groups (Phase 2). The interview sample consisted of 25 relatives (mean age 53.4 (standard deviation 12.7); women = 21/25) and 16 individuals with a first stroke (mean age = 55.7 (standard deviation 11.2); women = 7/16). The focus group sample size varied from 5 to 7 participants. An interview guide validated by experts was used. Audio content was transcribed verbatim and rigorously analyzed by two team members.
    Results: Services received by relatives are diversified, and relatives' perceptions range from receiving no services to being satisfied with services received. Even when participants were satisfied, ideal services were still desired: they would have liked to receive services earlier and without having to seek. Four main factors emerged as influencing the amount and quality of services received, including the individual's ability to seek.
    Conclusions: A gap remains between actual and ideal services for relatives post-stroke. It is crucial to legitimized relatives' role as clients and to systematically assess the patient's social environment in order to provide services in accordance with needs.

    Abstract Clients with mild stroke may present subtle deficits that have an impact on complex activities and roles. The purpose of this study was to explore the perceived quality of life of spouses, 3 months after the client with stroke was discharged to go home from acute care. A qalitative design based on a constructivist paradigm was used. Interviews were conducted with family members of the clients with mild stroke, 3 months after discharge. An interview guide was used and the audio content was transcribed, followed by a content analysis. In this study, eight interviews were conducted (mean age 56.9±9.2 years; men=2/8), and six essential themes emerged from the data. According to the participants, clients with mild stroke present sequelae that interfere with complex tasks (patient), increasing the burden on other family members who have to limit their personal activities (daily living). Sometimes, spouses were reported to act like a parent, which caused tensions in the relationship (conjugal relationship). Anxiety is related to the risk of stroke recurrence (relapse) and some family members present physical symptoms and a lack of energy (health). However, family members do not have access to services despite support from their relatives (services). The results of this exploratory study strongly suggest that even a 'mild' stroke has an impact on the daily lives of spouses and affects their quality of life.

    Abstract Although major stroke risk factors are well documented, little is known about which life circumstances are perceived to be related to the actual triggering of a first stroke. The purpose was to explore self-perceived spontaneously related life circumstances surrounding the trigger of a first stroke. A qualitative design with a phenomenological orientation was used. Nine individuals with a first stroke and less than 80 years of age were purposely recruited in 2 weeks after the stroke onset. An interview guide developed by experts was used. All interviews were transcribed verbatim and data analysis followed a rigorous process including team validation. All participants had in common a spontaneous reference to a family conflict regarding a specific event they tended to avoid surrounding the trigger of the stroke, which was temporarily resolved after the stroke onset. Essential themes emerging from the data refer to symbols such as a big heart and money issues as well as ambivalent feelings of responsibility, and guilt regarding social roles such as being a spouse or parent. This study provides a deeper understanding of the positive consequences the stroke had in temporarily resolving some family conflicts tainted by a lack of transparency and honesty regarding ambivalent feelings. Further exploration is needed as secondary prevention and health promotion campaigns could specifically target healthy transparent and honest family relationships as a potential protective factor against triggering a stroke, if these results are confirmed in future studies.

    Abstract During secondary contact between phylogenetically closely related species (sibling species) having diverged in allopatry, the maintenance of species integrity depends on intrinsic and extrinsic reproductive barriers. In kelps (Phaeophyceae), the observations of hybrids in laboratory conditions suggest that reproductive isolation is incomplete. However, not all interspecific crosses are successful, and very few hybrids have been observed in nature, despite the co-occurrence of many kelp species in sympatry. This suggests that there are reproductive barriers that maintain species integrity. In this study, we characterized the fine genetic structure of a secondary contact zone to clarify the extent of reproductive isolation between two sister species. In Lessonia nigrescens Bory (Laminariales, Phaeophyta) species complex, two cryptic species have been recently found out from gene phylogenies, and-waiting for a formal taxonomic description-we used their geographic distribution to name them (northern and southern species). We studied 12 populations, distributed along 50 km of coastline, and employed two molecular approaches, assigning individuals to phylogenetic species according to a diagnostic mitochondrial marker (351 individuals analyzed) and quantifying interspecific gene flow with four microsatellite markers (248 individuals analyzed). No hybridization or introgression was revealed, indicating complete reproductive isolation in natural conditions. Unexpectedly, our study demonstrated that the two species were strictly segregated in space. This absence of co-occurrence along the contact zone can partially explain the lack of hybridization, raising new interesting questions as to the mechanisms that limit sympatry at small spatial scales.

    Abstract Objective: To document the ethical issues regarding the systematic inclusion of relatives as clients in the post-stroke rehabilitation process.
    Methods: A two-phase qualitative design consisting of in-depth interviews with relatives and stroke-clients (Phase 1) and three focus groups with relatives, stroke-clients and health professionals (Phase 2). Data was audio recorded. Transcribed interviews and focus groups content were rigorously analyzed by two team members.
    Results: The interview sample was composed of 25 relatives and of 16 individuals with a first stroke whereas the three focus group sample size varied from 5 to 7 participants. Four main themes emerged: (1) overemphasis of caregiving role with an unclear legitimacy of relative to also be a client; (2) communication as a key issue to foster respect and a family-centered approach; (3) availability and attitudes of health professionals as a facilitator or a barrier to a family-centered approach; and (4) constant presence of relatives as a protective factor or creating a perverse effect.
    Conclusion/practice implications: The needs of relatives are well known. The next step is to legitimize their right to receive services and to acknowledge the combined clinical and ethical value of including them post-stroke. Interdisciplinary health care approaches and communication skills should be addressed.

    Abstract A major determinant of the geographic distribution of a species is expected to be its physiological response to changing abiotic variables over its range. The range of a species often corresponds to the geographic extent of temperature regimes the organism can physiologically tolerate. Many species have very distinct life history stages that may exhibit different responses to environmental factors. In this study we emphasized the critical role of the haploid microscopic stage (gametophyte) of the life cycle to explain the difference of edge distribution of two related kelp species. Lessonia nigrescens was recently identified as two cryptic species occurring in parapatry along the Chilean coast: one located north and the other south of a biogeographic boundary at latitude 29-30°S. Six life history traits from microscopic stages were identified and estimated under five treatments of temperature in eight locations distributed along the Chilean coast in order to (1) estimate the role of temperature in the present distribution of the two cryptic L. nigrescens species, (2) compare marginal populations to central populations of the two cryptic species. In addition, we created a periodic matrix model to estimate the population growth rate (λ) at the five temperature treatments. Differential tolerance to temperature was demonstrated between the two species, with the gametophytes of the Northern species being more tolerant to higher temperatures than gametophytes from the south. Second, the two species exhibited different life history strategies with a shorter haploid phase in the Northern species contrasted with considerable vegetative growth in the Southern species haploid stage. These results provide strong ecological evidence for the differentiation process of the two cryptic species and show local adaptation of the life cycle at the range limits of the distribution. Ecological and evolutionary implications of these findings are discussed.

    Abstract Phylogeographic studies are lacking in the Southern Hemisphere, and in particular in the south-eastern Pacific. To infer the possible scenario for the debated biogeographic transition zone located at 30-33 degrees S along the Chilean coast, we investigated whether there is a concordance between the phylogeographic pattern and the biogeographic transition in the intertidal kelp Lessonia nigrescens whose distribution is continuous across this transition zone. Using a combination of four makers located in the three genomic compartments (chloroplast, mitochondria and nucleus), we showed the presence of two main divergent lineages, possibly cryptic species. There was an exact match of the phylogeographic break with the 30 degrees S biogeographic transition zone, suggesting a common origin. The combined information given by the multilocus approach and by the population analysis suggested the occurrence of a budding speciation, with a northward range expansion.
