Wage losses in the year after breast cancer: Extent and determinants among Canadian women

This article is available open access through the publisher’s website at the link below. © The Author 2008.Background - Wage losses after breast cancer may result in considerable financial burden. Their assessment is made more urgent because more women now participate in the workforce and because breast cancer is managed using multiple treatment modalities that could lead to long work absences. We evaluated wage losses, their determinants, and the associations between wage losses and changes for the worse in the family's financial situation among Canadian women over the first 12 months after diagnosis of early breast cancer. Methods - We conducted a prospective cohort study among women with breast cancer from eight hospitals throughout the province of Quebec. Information that permitted the calculation of wage losses and information on potential determinants of wage losses were collected by three pretested telephone interviews conducted over the year following the start of treatment. Information on medical characteristics was obtained from medical records. The main outcome was the proportion of annual wages lost because of breast cancer. Multivariable analysis of variance using the general linear model was used to identify personal, medical, and employment characteristics associated with the proportion of wages lost. All statistical tests were two-sided. Results - Among 962 eligible breast cancer patients, 800 completed all three interviews. Of these, 459 had a paying job during the month before diagnosis. On average, these working women lost 27% of their projected usual annual wages (median = 19%) after compensation received had been taken into account. Multivariable analysis showed that a higher percentage of lost wages was statistically significantly associated with a lower level of education (Ptrend = .0018), living 50 km or more from the hospital where surgery was performed (P = .070), lower social support (P = .012), having invasive disease (P = .086), receipt of chemotherapy (P < .001), self-employment (P < .001), shorter tenure in the job (Ptrend < .001), and part-time work (P < .001). Conclusion - Wage losses and their effects on financial situation constitute an important adverse consequence of breast cancer in Canada.The Canadian Breast Cancer Research Alliance, Canadian Institutes of Health Research, and Fondation de l’Université Laval

Analyse philosophique des ressemblances entre l’Approche du rétablissement et le Modèle du Développement Humain et du Processus de Production du Handicap = Philosophical analysis of the similarities between the recovery approach and the Human Development Model-Disability Creation Process

Résumé Reconnue comme la référence en matière de bonnes pratiques en santé mentale, l’approche du rétablissement (AR) implique une considération pour le processus de rétablissement personnel de l’individu et l’adoption de pratiques axées vers le rétablissement (Commission de la santé mentale du Canada, 2015; Shepherd et al., 2008, 2010). Le modèle de développement humain et du processus de production du handicap (MDH-PPH) conçoit que la participation sociale des personnes résulte de l’interaction entre les facteurs personnels et les caractéristiques de l’environnement, ces domaines étant d’égale importance dans la compréhension des situations de handicap vécues par une personne, ou par un groupe ou une communauté partageant des caractéristiques personnelles communes dans un même contexte (Fougeyrollas, 2010). Nous présentons dans cet article une analyse des ressemblances philosophiques entre l’AR et le MDH-PPH et amorçons une réflexion sur l’apport mutuel de ces approches dans la lutte contre les obstacles sociaux qui nuisent à la participation sociale des personnes en situation de vulnérabilité/handicap. Pour ce faire, une analyse philosophique de nature herméneutique a été réalisée. Cinq angles d’analyse ont été choisis : 1) anthropologique; 2) environnemental; 3) axiologique; 4) éthique; 5) politique. Quatorze éléments de ressemblances ont été décelés entre les deux approches pour l’ensemble des angles analysés justifiant un apport mutuel dans la compréhension des situations de ces personnes. Abstract Now recognized as the gold standard for promoting good mental health practice, the recovery approach (RA) involves considering the individual's recovery process and adopting recovery-oriented practices by stakeholders, organizations, and society. (Mental Health Commission of Canada, 2015; Shepherd et al., 2010; Shepherd et al., 2008). The Human Development Model – Disability Creation Process (HDM-DCP) considers that social participation results from the interaction between personal and environmental factors. According to this model, these factors have equal importance in understanding disability situations experienced by a person or by a group, or a community sharing common personal characteristics in a same context (Fougeyrollas, 2010). This paper aims to analyze the philosophical similarities between the RA and the HDM-DCP. Besides, it intends to discuss the mutual contribution of these approaches in the fight against social obstacles that limit the social participation of people who are marginalized or in vulnerability/disability situations. For this purpose, we undertook a philosophical analysis of an hermeneutic nature. Five angles of analysis were chosen to identify the philosophical similarities between RA and HDM-DCP: 1) Anthropological; 2) Environmental; 3) Axiological; 4) Ethical; 5) Political. Fourteen elements (sub-themes) of similarities were identified between the two approaches from all the philosophical angles analyzed that justify a mutual contribution to understanding marginalized and vulnerable people's situations

Conceptualising ethical issues in the conduct of research: Results from a critical and systematic literature review

This article concerns  the ways in which authors from various fields conceptualise the ethical issues arising in the conduct of research. We reviewed critically and systematically the literature concerning the ethics of conducting research in order to engage in a reflection about the vocabulary and conceptual categories used in the publications reviewed. To understand better how the ethical issues involved in conducting research are conceptualised in the publications reviewed, we 1) established an inventory of the conceptualisations reviewed, and 2) we critically assessed them. We found that the publications reviewed mostly showed examples of descriptive ethics, in that most authors describe ethical issues without reflecting much on them, which could be explained both by 1) a lack of ethical education in research contexts, and 2) by the fact that we do not know what researchers know (or do not) about ethical issues. Additionally, the definitions identified in the publications are scarce and at times imprecise, but this seems more to point out the ethical vocabulary’s difficulties in certain contexts. Further, very few authors offer proper conceptualisations of the ethical issues arising in conducting research. When dealing with vast arrays of ethical issues to conceptualise, perhaps one ought to remember that some typologies already exist that could guide further reflection and help understand other realities for which the current ethical vocabulary may be lacking. We believe that combining the reviewed typologies, both with other well-developed typologies and critical reflection, could help support better ethical practice in conducting research

Sharp interface limits of phase-field models

The use of continuum phase-field models to describe the motion of well-defined interfaces is discussed for a class of phenomena, that includes order/disorder transitions, spinodal decomposition and Ostwald ripening, dendritic growth, and the solidification of eutectic alloys. The projection operator method is used to extract the ``sharp interface limit'' from phase field models which have interfaces that are diffuse on a length scale $\xi$. In particular,phase-field equations are mapped onto sharp interface equations in the limits $\xi \kappa \ll 1$ and $\xi v/D \ll 1$, where $\kappa$ and $v$ are respectively the interface curvature and velocity and $D$ is the diffusion constant in the bulk. The calculations provide one general set of sharp interface equations that incorporate the Gibbs-Thomson condition, the Allen-Cahn equation and the Kardar-Parisi-Zhang equation.Comment: 17 pages, 9 figure

A Recombinant Rift Valley Fever Virus Glycoprotein Subunit Vaccine Confers Full Protection against Rift Valley Fever Challenge in Sheep

Citation: Faburay, B., Wilson, W. C., Gaudreault, N. N., Davis, A. S., Shivanna, V., Bawa, B., . . . Richt, J. A. (2016). A Recombinant Rift Valley Fever Virus Glycoprotein Subunit Vaccine Confers Full Protection against Rift Valley Fever Challenge in Sheep. Scientific Reports, 6, 12. doi:10.1038/srep27719Rift Valley fever virus (RVFV) is a mosquito-borne zoonotic pathogen causing disease outbreaks in Africa and the Arabian Peninsula. The virus has great potential for transboundary spread due to the presence of competent vectors in non-endemic areas. There is currently no fully licensed vaccine suitable for use in livestock or humans outside endemic areas. Here we report the evaluation of the efficacy of a recombinant subunit vaccine based on the RVFV Gn and Gc glycoproteins. In a previous study, the vaccine elicited strong virus neutralizing antibody responses in sheep and was DIVA (differentiating naturally infected from vaccinated animals) compatible. In the current efficacy study, a group of sheep (n=5) was vaccinated subcutaneously with the glycoprotein-based subunit vaccine candidate and then subjected to heterologous challenge with the virulent Kenya-128B-15 RVFV strain. The vaccine elicited high virus neutralizing antibody titers and conferred complete protection in all vaccinated sheep, as evidenced by prevention of viremia, fever and absence of RVFV-associated histopathological lesions. We conclude that the subunit vaccine platform represents a promising strategy for the prevention and control of RVFV infections in susceptible hosts

Laugh Like You Mean It:Authenticity Modulates Acoustic, Physiological and Perceptual Properties of Laughter

Several authors have recently presented evidence for perceptual and neural distinctions between genuine and acted expressions of emotion. Here, we describe how differences in authenticity affect the acoustic and perceptual properties of laughter. In an acoustic analysis, we contrasted spontaneous, authentic laughter with volitional, fake laughter, finding that spontaneous laughter was higher in pitch, longer in duration, and had different spectral characteristics from volitional laughter that was produced under full voluntary control. In a behavioral experiment, listeners perceived spontaneous and volitional laughter as distinct in arousal, valence, and authenticity. Multiple regression analyses further revealed that acoustic measures could significantly predict these affective and authenticity judgements, with the notable exception of authenticity ratings for spontaneous laughter. The combination of acoustic predictors differed according to the laughter type, where volitional laughter ratings were uniquely predicted by harmonics-to-noise ratio (HNR). To better understand the role of HNR in terms of the physiological effects on vocal tract configuration as a function of authenticity during laughter production, we ran an additional experiment in which phonetically trained listeners rated each laugh for breathiness, nasality, and mouth opening. Volitional laughter was found to be significantly more nasal than spontaneous laughter, and the item-wise physiological ratings also significantly predicted affective judgements obtained in the first experiment. Our findings suggest that as an alternative to traditional acoustic measures, ratings of phonatory and articulatory features can be useful descriptors of the acoustic qualities of nonverbal emotional vocalizations, and of their perceptual implications

Racial/ethnic differences in job loss for women with breast cancer

IntroductionWe examined race/ethnic differences in treatment-related job loss and the financial impact of treatment-related job loss, in a population-based sample of women diagnosed with breast cancer.MethodsThree thousand two hundred fifty two women with non-metastatic breast cancer diagnosed (August 2005-February 2007) within the Los Angeles County and Detroit Metropolitan Surveillance Epidemiology and End Results registries, were identified and asked to complete a survey (mean time from diagnosis = 8.9&nbsp;months). Latina and African American women were over-sampled (n = 2268, eligible response rate 72.1%).ResultsOne thousand one hundred eleven women (69.6%) of working age (&lt;65&nbsp;years) were working for pay at time of diagnosis. Of these women, 10.4% (24.1% Latina, 10.1% African American, 6.9% White, p &lt; 0.001) reported that they lost or quit their job since diagnosis due to breast cancer or its treatment (defined as job loss). Latina women were more likely to experience job loss compared to White women (OR = 2.0, p = 0.013)), independent of sociodemographic factors. There were no significant differences in job loss between African American and White women, independent of sociodemographic factors. Additional adjustments for clinical and treatment factors revealed a significant interaction between race/ethnicity and chemotherapy (p = 0.007). Among women who received chemotherapy, Latina women were more likely to lose their job compared to White women (OR = 3.2, p &lt; 0.001), however, there were no significant differences between Latina and White women among those who did not receive chemotherapy. Women who lost their job were more likely to experience financial strain (e.g. difficulty paying bills 27% vs. 11%, p &lt; 0.001).ConclusionJob loss is a serious consequence of treatment for women with breast cancer. Clinicians and staff need to be aware of aspects of treatment course that place women at higher risk for job loss, especially ethnic minorities receiving chemotherapy

Time trends in social contacts before and during the COVID-19 pandemic: the CONNECT study

Background Since the beginning of the COVID-19 pandemic, many countries, including Canada, have adopted unprecedented physical distancing measures such as closure of schools and non-essential businesses, and restrictions on gatherings and household visits. We described time trends in social contacts for the pre-pandemic and pandemic periods in Quebec, Canada. Methods CONNECT is a population-based study of social contacts conducted shortly before (2018/2019) and during the COVID-19 pandemic (April 2020 – February 2021), using the same methodology for both periods. We recruited participants by random digit dialing and collected data by self-administered web-based questionnaires. Questionnaires documented socio-demographic characteristics and social contacts for two assigned days. A contact was defined as a two-way conversation at a distance ≤ 2 m or as a physical contact, irrespective of masking. We used weighted generalized linear models with a Poisson distribution and robust variance (taking possible overdispersion into account) to compare the mean number of social contacts over time and by socio-demographic characteristics. Results A total of 1291 and 5516 Quebecers completed the study before and during the pandemic, respectively. Contacts significantly decreased from a mean of 8 contacts/day prior to the pandemic to 3 contacts/day during the spring 2020 lockdown. Contacts remained lower than the pre-COVID period thereafter (lowest = 3 contacts/day during the Christmas 2020/2021 holidays, highest = 5 in September 2020). Contacts at work, during leisure activities/in other locations, and at home with visitors showed the greatest decreases since the beginning of the pandemic. All sociodemographic subgroups showed significant decreases of contacts since the beginning of the pandemic. The mixing matrices illustrated the impact of public health measures (e.g. school closure, gathering restrictions) with fewer contacts between children/teenagers and fewer contacts outside of the three main diagonals of contacts between same-age partners/siblings and between children and their parents. Conclusion Physical distancing measures in Quebec significantly decreased social contacts, which most likely mitigated the spread of COVID-19
