RESUMO

During the first 2 years of the COVID-19 pandemic in Canada, tens of thousands of refugee claimants faced worsened resettlement stress with limited access to services. Community-based programs that address social determinants of health faced significant disruptions and barriers to providing care as a result of public health restrictions. Little is known about how and if these programs managed to function under these circumstances. This qualitative study aims to understand how community-based organizations based in Montreal, Canada, responded to public health directives and the challenges and opportunities that arose as they attempted to deliver services to asylum seekers during the COVID-19 pandemic. We used an ethnographic ecosocial framework generating data through in-depth semi-structured interviews with nine service providers from seven different community organizations and 13 refugee claimants who were purposively sampled, as well as participant observation during program activities. Results show that organizations struggled to serve families due to public health regulations that limited in-person services and elicited anxiety about putting families at risk. First, we found a central trend in service delivery that was the transition from in-person services to online, which presented specific challenges including (a) technological and material barriers, (b) threats to claimants' sense of privacy and security, (c) meeting linguistic diversity needs, and (d) disengagement from online activities. At the same time, opportunities of online service delivery were identified. Second, we learned that organizations adapted to public health regulations by pivoting and expanding their services as well as fostering and navigating new partnerships and collaborations. These innovations not only demonstrated the resilience of community-organizations, but also revealed tensions and areas of vulnerability. This study contributes to a better understanding of the limits of online service delivery for this population and also captures the agility and limits of community-based programs in the COVID-19 context. Its results can inform decision-makers, community groups and care providers to develop improved policies and program models that preserve what are clearly essential services for refugee claimants.

RESUMO

Oxytocin and its paralogue, vasopressin, are widely studied biomarkers in relation to pregnancy and birth, maternal and social behavior, and mental health. Epigenetics is a biological mechanism that mediates the link between environmental influences and behavioral patterns. In a candidate gene approach, we describe here a DNA methylation assay of two regions within the oxytocin system, using human buccal cells and next-generation sequencing. Two nanograms of DNA were sufficient to assess the DNA methylation status of 28 CpG sites (22 corresponding to the oxytocin receptor and 6 corresponding to the vasopressin/oxytocin intergenic region). This method proved to be non-invasive for the participants, and reproducible; its validity remains to be confirmed alongside other biomarkers of gene function.

RESUMO

PURPOSE OF REVIEW: Understanding variability in developmental outcomes following exposure to early life adversity (ELA) has been an area of increasing interest in psychiatry, as resilient outcomes are just as prevalent as negative ones. However, resilient individuals are understudied in most cohorts and even when studied, resilience is typically defined as an absence of psychopathology. This review examines current approaches to resilience and proposes more comprehensive and objective ways of defining resilience. RECENT FINDINGS: Of the 36 studies reviewed, the most commonly used measure was the Strengths and Difficulties Questionnaire (n = 6), followed by the Child Behavior Checklist (n = 5), the Resilience Scale for Chinese Adolescents (n = 5), the Rosenberg Self-Esteem Scale (n = 4), and the Child and Youth Resilience Scale (n = 3). SUMMARY: This review reveals that studies tend to rely on self-report methods to capture resilience which poses some challenges. We propose a complementary measure of child resilience that relies on more proactive behavioral and observational indicators; some of our preliminary findings are presented. Additionally, concerns about the way ELA is characterized as well as the influence of genetics on resilient outcomes prompts further considerations about how to proceed with resiliency research.

RESUMO

Theory of mind, the ability to represent the mental states of others, is an important social cognitive process, which contributes to the development of social competence. Recent research suggests that interactions between gene and environmental factors, such as oxytocin receptor gene (OXTR) polymorphisms and maternal parenting behavior, may underlie individual differences in children's theory of mind. However, the potential influence of DNA methylation of OXTR remains unclear. The current study investigated the roles of OXTR methylation, maternal behavior, and their statistical interaction on toddlers' early emerging theory of mind abilities. Participants included a community sample of 189 dyads of mothers and their 2- to 3-year-old children, whose salivary DNA was analyzed. Results indicated that more maternal structuring behavior was associated with better performance, on a battery of three theory of mind tasks, while higher OXTR methylation within exon 3 was associated with poorer performance. A significant interaction also emerged, such that OXTR methylation was related to theory of mind among children whose mothers displayed less structuring, when controlling for children's age, sex, ethnicity, number of child-aged siblings, verbal ability, and maternal education. Maternal structuring behavior may buffer the potential negative impact of hypermethylation on OXTR gene expression and function.

RESUMO

PROBLEM: Although prenatal depression is a risk factor for postpartum depression, current screening tools for prenatal depression fail to predict postpartum depression in some marginalized populations. BACKGROUND: The assessment of other risk factors along with prenatal depression may be needed to improve prediction of postpartum depression and these risk factors may be specific to immigrants. AIMS: We investigated the predictive utility of several measures in relation to postpartum depressive symptoms in: recent immigrants, less recent immigrants and Canadian-born women. METHODS: Measures pertaining to psychosocial risk factors, generalized anxiety, perinatal somatic and depressive symptoms were administered. Data were collected at 4 time-points: 12-14 weeks and 24-28 weeks gestation as well as 1-week and 8-weeks postpartum. Perinatal factors were entered into 3 different regression models to predict postpartum depressive symptoms at the last time-point. FINDINGS: Canadian-born women reported significantly more psychosocial risk factors compared to immigrant women. The best predictors of postpartum depressive symptoms at 8-weeks among Canadian-born women included psychosocial risk, prenatal anxiety and depressive symptoms as well as early postpartum depressive symptoms. Prenatal somatic symptoms predicted postpartum depressive symptoms among recent immigrants. Depressive symptoms at 1-week postpartum and the lack of an emotionally supportive partner were significant predictors of postpartum depressive symptoms for both Canadian-born and immigrant women. DISCUSSION: There appears to be both overlapping and distinct predictors of postpartum depressive symptoms for immigrant and Canadian-born women. CONCLUSION: The findings from this research will help guide routine screening options and patient-centered approaches to management of perinatal depression for diverse populations.

RESUMO

The present study investigated the association of perinatal depression (PD) with differential methylation of 3 genomic regions among mother and child dyads: exon 3 within the oxytocin receptor (OXTR) gene and 2 intergenic regions (IGR) between the oxytocin (OXT) and vasopressin (AVP) genes. Maternal PD was assessed at 5 time-points during pregnancy and postpartum. Four groups were established based on Edinburgh Postnatal Depression Scale (EPDS) cut-off scores: no PD, prenatal or postpartum depressive symptoms only and persistent PD (depressive symptoms both prenatally and postpartum). Salivary DNA was collected from mothers and children at the final time-point, 2.9years postpartum. Mothers with persistent PD had significantly higher overall OXTR methylation than the other groups and this pattern extended to 16/22 individual CpG sites. For the IGR, only the region closer to the AVP gene (AVP IGR) showed significant differential methylation, with the persistent PD group displaying the lowest levels of methylation overall, but not for individual CpG sites. These results suggest that transient episodes of depression may not be associated with OXTR hypermethylation. Validation studies need to confirm the downstream biological effects of AVP IGR hypomethylation as it relates to persistent PD. Differential methylation of the OXTR and IGR regions was not observed among children exposed to maternal PD. The consequences of OXTR hypermethylation and AVP IGR hypomethylation found in mothers with persistent PDS may not only impact the OXT system, but may also compromise maternal behavior, potentially resulting in negative outcomes for the developing child.

RESUMO

The goal of the study was to examine the reasons given by parents who accepted or refused the HPV vaccine for their daughters in the context of a free provincial school-based vaccination program. A random sample of parents of 9-10 y old girls completed a mail-in questionnaire. Parents' responses to 2 open-ended questions were assessed using content analysis. Coding themes were derived from the Health Belief Model. 806 parents returned and answered the relevant items. 88% of these parents decided to vaccinate their daughter. The primary reasons for parents' acceptance was the perceived benefits (e.g., health protection, cancer/HPV prevention) and cues to action (e.g., physician recommendation, trusting the school vaccine program). Reasons for parental refusal included barriers (e.g., fear of side effects) and low susceptibility (e.g., their daughter is not at risk). Both groups of parents had unanswered questions, doubts and often inaccurate information. This study provides unique insight into parents' perspectives concerning the decision making process for their daughter. There appears to be a need for accurate and complete information to assure informed HPV vaccine decision-making by parents and to increase HPV vaccine uptake.

RESUMO

The present study examined whether public funding for in vitro fertilization (IVF) in Quebec, Canada was associated with differential access among Canadian-born infertility patients and those born outside of Canada. Anonymous demographic questionnaires were completed at 3 time points: 2 weeks before the implementation of public funding, 2 weeks after, and 8 months later. Almost half the patients were not born in Canada and of these, 35 % were recent immigrants to Canada. While patients born outside Canada were generally better educated than Canadian-born patients, they were more likely to be unemployed and have lower incomes. Following public funding, there was an overall increase in patients with lower incomes and lower levels of education. Canadian-born patients were more likely than immigrant patients to consult for secondary infertility. Patients born outside Canada tended to be older and nulliparous, suggesting that they may have delayed treatment seeking due to financial and other barriers. The results indicate that public funding reduces health disparities in access to IVF.

RESUMO

Low sexual desire concomitant with feelings of distress is reported in naturally and surgically menopausal women. A combination of estradiol (E2) and testosterone (T) restores sexual desire and interest in these women. The central mechanisms by which E2 and T act to restore desire are poorly understood. Here we examined the effect of chronic treatment with testosterone propionate (TP) administered by a sc SILASTIC brand capsule in aged ovary-intact female rats. Females were first treated with TP alone, followed by a second phase when TP was administered in combination with estradiol benzoate (EB; 10 µg) by sc injection 48 h prior to testing (EB+TP). Each phase consisted of 5 test days at 4-d intervals. Appetitive and consummatory female sexual behaviors were observed in bilevel chambers, and plasma E2 and T concentrations were measured with ELISA. Sexual solicitations and hops and darts were facilitated by the highest TP dose, and the lordosis quotient was increased by the two highest TP doses when administered alone, coinciding with an increase in plasma T, but those behavioral effects were not maintained across time. The lordosis quotient was inversely related to the TP dose in the EB+TP phase. These results suggest that the administration of TP by sc capsules to aged female rats facilitates appetitive and consummatory sexual behaviors; however, chronic treatment appears to be inhibitory. This is the first study to assess sexual behavior after SILASTIC brand implants of TP in the aged female rat. Additional research is needed to elucidate the mechanisms underlying the effects of T on female sexual function.
