Appendice. Pour une meilleure immunité : l’approche du parcours de vie pour une longévité en bonne santé

Cette publication est une annexe au document technique "Building better immunity : Une approche du parcours de vie pour une longévité en bonne santé", avec les contributions de plusieurs experts en la matière au sein et en dehors de l'Organisation panaméricaine de la santé (OPS). Cette annexe fournit des exemples d'activités au sein du programme national de vaccination qui peuvent améliorer les taux de couverture et réduire les occasions manquées pour quatre groupes de population : les femmes enceintes, les adolescents, les travailleurs de la santé et les personnes âgées. Ces exemples traduisent les principes et les concepts de l'approche fondée sur le parcours de vie en activités concrètes, qui peuvent être utilisées par les responsables des programmes nationaux de vaccination et par les vaccinateurs, respectivement, pour améliorer les taux de couverture vaccinale. Ces quatre groupes représentent des étapes de la vie pour lesquelles il existe des vaccins très efficaces et qui peuvent grandement influencer leurs capacités sanitaires. L'application des séries primaires, des rappels et des doses de vaccin de rattrapage dans ces groupes est essentielle pour combler les déficits d'immunité émergents. Les activités sont regroupées en huit composantes : (i) gestion et plaidoyer, (ii) équité, (iii) ressources humaines et financement, (iv) organisation et prestation de services, (v) génération de la demande et engagement communautaire, (vi) systèmes d'information, (vii) formation et (viii) évaluation et recherche. Les exemples doivent être évalués, adaptés, mis en œuvre et éventuellement élargis par les États membres pour s'aligner sur les contextes nationaux et locaux. Ce document s'inscrit dans le cadre des efforts déployés par l'OPS pour promouvoir l'application d'une approche de la vaccination fondée sur le parcours de vie dans les pays et territoires des Amériques et pour aider les ministères de la santé à mettre en place des stratégies de santé publique aux niveaux infranational et local afin de préserver la santé et le bien-être des personnes de tous âges.

Pesquisa de base populacional sobre envelhecimento utilizando a abordagem de curso de vida

Esta publicação, que faz parte da série Década do Envelhecimento Saudável nas Américas: Situação e Desafios, tem como objetivo apresentar conhecimentos atuais sobre a situação de saúde e bem-estar das pessoas idosas na Região das Américas durante a Década do Envelhecimento Saudável das Nações Unidas (2021–2030). Além disso, a fim de guiar as ações voltadas a um envelhecimento saudável, o relatório destaca a relevância da abordagem de curso de vida para enfrentar as dificuldades relacionadas ao envelhecimento e à velhice nas sociedades da América Latina e do Caribe, examinando como as pesquisas e evidências podem contribuir nessa área. No que consiste a abordagem do curso de vida? Como pode contribuir com uma perspectiva integral sobre o envelhecimento populacional? Qual é o papel que desempenha na elaboração de políticas públicas voltadas para pessoas idosas? Como as pesquisas de base populacional podem ajudar na implementação da estratégia de curso de vida? A análise dessas questões favorecerá um debate necessário, que precisa ser travado entre autoridades governamentais, instituições públicas e organismos internacionais. A abordagem sugerida põe o foco nos aspectos dinâmicos e singulares das trajetórias individuais e geracionais, convidando-nos a ir além de considerações parciais definidas por limiares de idade, sexo, gênero, etnia ou território. A Década do Envelhecimento Saudável é um período propício para direcionar as ações para a geração de dados, a implementação de políticas públicas e o monitoramento dos resultados, três esferas cruciais que permitirão avançar para um envelhecimento saudável ao longo de todo o curso de vida.

Stressful life events and the occurrence of skin cancer.

OBJECTIVE: It is widely acknowledged that emotional states can influence skin conditions, yet limited research has delved into the impact of stress on skin cancer development. This retrospective study sought to expand the perspective on skin cancer risk factors by investigating the complex relationship between stressful life events and the incidence of skin cancer. METHODS: The sample included 268 individuals followed-up in a dermatological clinic, in three groups: Patients who had previously been diagnosed with cutaneous melanoma and are currently in remission (32%), those who had been diagnosed with non-melanoma skin cancer (30%), and a control group who are at risk for skin cancer (38%). Participants filled in questionnaires regarding childhood and adulthood life events, and loss and gain of resources following their subjectively most stressful event in adulthood. Multinomial logistic regression was used to examine the associations of life events with skin cancer occurrence, and mediating and moderating effects of resource loss/gain. RESULTS: Adverse childhood experiences were associated with melanoma occurrence, with the melanoma group reporting significantly more such experiences compared to the control group (p < 0.001). Resource loss from subjectively significant stressful life events in adulthood partially mediated the association between adverse childhood experiences and melanoma incidence. CONCLUSIONS: The findings suggest that there may be intricate connections between stress, life events, adaptation to change, and skin cancer, which future research may further unravel. This study underscores the need for a more comprehensive approach to stress management, coping strategies development, and skin cancer prevention in healthcare settings.

[The psychotrauma prevention algorithm, a paramedical pilot study]. / L'algorithme de prévention du psychotraumatisme, une étude pilote paramédicale.

The aim of the psychotrauma prevention algorithm is to limit the occurrence of psychotrauma in a subject who has experienced a serious life event, by carrying out an initial assessment to define the severity criterion and the monitoring modality best suited to his or her clinical condition. This approach is in line with the philosophy of outreach and the ethics of concern. Recontacting the patient during the course of treatment helps to maintain the therapeutic link and prevent any deterioration in his condition, thus limiting the risk of his traumatic state becoming chronic.

Positive psychosocial factors may protect against perceived stress in people with systemic lupus erythematosus with and without trauma history.

OBJECTIVE: Trauma history is associated with SLE onset and worse patient-reported outcomes; perceived stress is associated with greater SLE disease activity. Stress perceptions vary in response to life events and may be influenced by psychosocial factors. In an SLE cohort, we examined whether stressful events associated with perceived stress, whether psychosocial factors affected perceived stress, and whether these relationships varied by prior trauma exposure. METHODS: This is a cross-sectional analysis of data from the California Lupus Epidemiology Study, an adult SLE cohort. Multivariable linear regression analyses controlling for age, gender, educational attainment, income, SLE damage, comorbid conditions, glucocorticoids ≥7.5 mg/day and depression examined associations of recent stressful events (Life Events Inventory) and positive (resilience, self-efficacy, emotional support) and negative (social isolation) psychosocial factors with perceived stress. Analyses were stratified by lifetime trauma history (Brief Trauma Questionnaire (BTQ)) and by adverse childhood experiences (ACEs) in a subset. RESULTS: Among 242 individuals with SLE, a greater number of recent stressful events was associated with greater perceived stress (beta (95% CI)=0.20 (0.07 to 0.33), p=0.003). Positive psychosocial factor score representing resilience, self-efficacy and emotional support was associated with lower perceived stress when accounting for number of stressful events (-0.67 (-0.94 to -0.40), p<0.0001); social isolation was associated with higher stress (0.20 (0.14 to 0.25), p<0.0001). In analyses stratified by BTQ trauma and ACEs, associations of psychosocial factors and perceived stress were similar between groups. However, the number of recent stressful events was significantly associated with perceived stress only for people with BTQ trauma (0.17 (0.05 to 0.29), p=0.0077) and ACEs (0.37 (0.15 to 0.58), p=0.0011). CONCLUSION: Enhancing positive and lessening negative psychosocial factors may mitigate deleterious perceived stress, which may improve outcomes in SLE, even among individuals with a history of prior trauma who may be more vulnerable to recent stressful events.

Borderline personality traits mediate the relationship between negative life events and nonsuicidal self-injury in a clinical sample with youth depression.

BACKGROUND: Borderline personality traits play a significant role in nonsuicidal self-injury (NSSI), particularly in depressed youths. NSSI is also highly correlated with negative life events. This research aimed to explore the connections between negative life events, borderline personality traits, and NSSI. METHODS: The study included 338 depressed youth aged 13 to 25 years. Self-reported measures and clinical interviews were utilized to evaluate the depressive symptoms, borderline personality traits, negative life events, and NSSI behaviours of these participants. Identifying variables linked to NSSI was the aim of our analysis, and we also conducted a mediation analysis to look into the influence of borderline traits on the connection between negative life events and NSSI. RESULTS: Of the 338 depressed youth, approximately 59.47% (201/338) displayed NSSI, which was associated with greater clinical severity. Borderline traits had an independent influence on NSSI and it partially explained the connection between negative life events and NSSI, even when accounting for depression symptoms. Depressed youth who were more vulnerable to NSSI behaviours often experienced negative life events such as interpersonal relationships, academic pressure, being punished, and loss. CONCLUSIONS: Our research suggests that depressed youth who experience more negative life events are more likely to experience NSSI, and negative life events indirectly influence nonsuicidal self-injury through borderline personality traits. Implementing interventions focused on mitigating borderline symptoms could be a promising therapeutic approach for addressing NSSI in young people.

Immune cell phenotype and function patterns across the life course in individuals from rural Uganda.

Background: To determine the pattern of immune cell subsets across the life span in rural sub-Saharan Africa (SSA), and to set a reference standard for cell subsets amongst Africans, we characterised the major immune cell subsets in peripheral blood including T cells, B cells, monocytes, NK cells, neutrophils and eosinophils, in individuals aged 3 to 89 years from Uganda. Methods: Immune phenotypes were measured using both conventional flow cytometry in 72 individuals, and full spectrum flow cytometry in 80 individuals. Epstein-Barr virus (EBV) IFN-γ T cell responses were quantified in 332 individuals using an ELISpot assay. Full blood counts of all study participants were also obtained. Results: The percentages of central memory (TCM) and senescent CD4+ and CD8+ T cell subsets, effector memory (TEM) CD8+ T cells and neutrophils increased with increasing age. On the other hand, the percentages of naïve T (TN) and B (BN) cells, atypical B cells (BA), total lymphocytes, eosinophils and basophils decreased with increasing age. There was no change in CD4+ or CD8+ T effector memory RA (TEMRA) cells, exhausted T cells, NK cells and monocytes with age. Higher eosinophil and basophil percentages were observed in males compared to females. T cell function as measured by IFN-γ responses to EBV increased with increasing age, peaking at 31-55 years. Conclusion: The percentages of cell subsets differ between individuals from SSA compared to those elsewhere, perhaps reflecting a different antigenic milieu. These results serve as a reference for normal values in this population.

Effect of PTSD treatment on cardiovascular reactivity during trauma memory recall and correspondence with symptom improvement.

ABSTRACTBackground: Prior research has shown PTSD treatment leads to reductions in cardiovascular reactivity during trauma recall, but the extent to which such reductions are associated with changes in PTSD symptoms is less clear. Moreover, such relationships have not been investigated in a cognitively focused PTSD treatment.Objective: To examine changes in cardiovascular reactivity to the trauma memory in patients receiving cognitive processing therapy (CPT), CPT with a written trauma account, and a written account only condition. We also examined the association of such changes with symptom improvement.Method: 118 women with PTSD secondary to interpersonal violence completed pre- and post-treatment assessments of PTSD symptoms and cardiovascular reactivity during a script-driven imagery task.Results: Results indicated a significant but modest reduction in cardiovascular reactivity in CPT conditions. Changes in cardiovascular reactivity and reexperiencing symptoms were significantly associated among the whole sample. Among individuals with the greatest reactivity to the trauma memory at pretreatment, associations were also seen with changes in total PTSD, numbing, and trauma-related guilt.Conclusions: Results indicate that previous findings on the effect of PTSD treatment on cardiovascular reactivity during trauma recall extend to cognitively oriented treatment. Baseline cardiovascular reactivity may influence the extent to which reductions in PTSD symptoms and reactivity during trauma recall are related.

Cognitive Processing Therapy leads to reduced heart rate reactivity when recalling a trauma memory.Decreases in heart rate reactivity are associated with reduced reexperiencing symptoms.Changes in heart rate reactivity and PTSD symptoms are more closely related among patients with greater pretreatment reactivity.

Associations of recent stressful life events with anxiety symptoms among Chinese adolescents with a consideration of family functioning.

Background: The association between stressful life events (SLEs) and adolescent anxiety symptoms has been extensively studied, but the specific impacts of different SLEs domains remain inconclusive. Moreover, limited research has examined the role of family functioning in these associations.Objective: This study aimed to investigate the associations between various recent SLEs and adolescent anxiety symptoms and explore the role of family functioning.Methods: Data were obtained from the second phase of the Longitudinal Study of Adolescents' Mental and Behavioral Well-being Research in Guangzhou, China. A total of 10,985 students (51.9% boys; mean [SD] age, 15.3 [1.5] years) from forty middle schools participated in the study in 2022 and completed a self-report questionnaire assessing anxiety symptoms, SLEs, and family functioning using the Generalized Anxiety Disorder-7 (GAD-7), Adolescent Self-rating Life Events Checklist (ASLEC; including five subscales: interpersonal stress, academic stress, punishment-related stress, loss-related stress, and adaptation-related stress), and the adapted Chinese version of the Family Assessment Device (FAD), respectively. Linear mixed-effects models were performed and the moderation role of family functioning was also examined.Results: The fully adjusted model revealed that a 1-SD increase in the overall ASLEC score was associated with higher levels of anxiety symptoms (ß = 2.23, 95%CI: 2.15-2.32). Among various SLEs domains, the academic domain shows the most significant association (ß = 2.25, 95%CI: 2.17-2.33). Family functioning exerted an independent protective influence on anxiety symptoms, with each 1-SD increase in FAD scores negatively associated with anxiety symptoms (ß = -2.11, 95%CI: - 2.29 to - 1.93) in the adjusted model. Moreover, family functioning significantly buffered the impacts of overall SLEs and each domain, except for adaptation-related SLEs, on anxiety symptoms.Conclusion: Higher recent SLEs levels were associated with increased anxiety symptoms among adolescents, with academic SLEs showing the greatest association. Positive family functioning had both direct and buffering influences on anxiety symptoms.

Higher levels of recent stressful life events may increase adolescents' anxiety symptoms.Academic stressful life events show the greatest association with anxiety symptoms.Family functioning may be a promising intervention target for adolescent anxiety symptoms.

Associations between life course longitudinal growth and hip shapes at ages 60-64 years: evidence from the MRC National Survey of Health and Development.

OBJECTIVE: We sought to examine associations between height gain across childhood and adolescence with hip shape in individuals aged 60-64 years from the Medical Research Council National Survey of Health and Development, a nationally representative British birth cohort. METHODS: Height was measured at ages 2, 4, 6, 7, 11 and 15 years, and self-reported at age 20 years. 10 modes of variation in hip shape (HM1-10), described by statistical shape models, were previously ascertained from DXA images taken at ages 60-64 years. Associations between (1) height at each age; (2) Super-Imposition by Translation And Rotation (SITAR) growth curve variables of height size, tempo and velocity; and (3) height gain during specific periods of childhood and adolescence, and HM1-10 were tested. RESULTS: Faster growth velocity was associated with a wider, flatter femoral head and neck, as described by positive scores for HM6 (regression coefficient 0.014; 95% CI 0.08 to 0.019; p<0.001) and HM7 (regression coefficient 0.07; 95% CI 0.002 to 0.013; p=0.009), and negative scores for HM10 (regression coefficient -0.006; 95% CI -0.011 to 0.00, p=0.04) and HM2 (males only, regression coefficient -0.017; 95% CI -0.026 to -0.09; p<0.001). Similar associations were observed with greater height size and later height tempo. Examination of height gains during specific periods of childhood and adolescence identified those during the adolescence period as being most consistently associated. CONCLUSION: Our analyses suggest that individual growth patterns, particularly in the adolescent period, are associated with modest variations in hip shape at 60-64 years, which are consistent with features seen in osteoarthritis.

Sports participation moderates the risk of family-specific negative life events on alcohol use among adolescents: Evidence from the longitudinal MyLife study.

Negative life events (NLE) have been associated with increased alcohol use (AU) during adolescence. However, whether this risk association may be modified by leisure activities such as sports participation (SP) remains poorly understood. This study examined whether accumulated family-specific NLE in particular were associated with greater AU, and if so, whether SP moderated this association to reduce AU among high-NLE adolescents. We examined five annual assessments from a nationwide cohort of 3,422 Norwegian adolescents (13-15 year-olds; 55.3 % girls at baseline) who participated in the MyLife study. At each assessment, adolescents reported their AU on the Alcohol Use Disorders Identification Test-Concise (AUDIT-C), the number of family-specific NLE in the past 12 months, SP days in the past 30 days, and multiple sociodemographic and individual-level characteristics (covariates). Changes over time in AU as a function of NLE, SP, and their interaction (NLExSP) were examined with a set of partially nested growth curve models. AU increased non-linearly over time in all models. The fully adjusted best-fitting model showed significant NLExSP interactions (estimate = -0.013, 95% CI [-0.02, -0.006]), such that the initial AUDIT-C scores were lower for high-NLE adolescents with high SP and greater for high-NLE adolescents with low SP. Further, linear increases in AU over time were marginally steeper for high-NLE adolescents with high SP (NLExSPxTime estimate = 0.034, 95% CI [-0.0002, 0.007]). Thus, SP appeared to have a protective role in reducing AU for high-NLE youth primarily during middle school years. Prevention efforts thus may utilize organized sports for youth facing family-specific NLE as a resource early on.

Prenatal maternal negative life events associated with child emotional and behavioral problems in the French EDEN cohort.

INTRODUCTION: Prenatal negative life events (NLEs) have been linked to adverse health outcomes in children. However, few studies examine this relationship during late childhood using trajectory analyses. Additionally, the impact of specific NLEs domains on child development remains unclear. This study aims to longitudinally explore the association between NLEs (cumulative score and specific NLEs domains) and child outcomes from birth to late childhood. METHODS: 1135 mother-child pairs from the French EDEN cohort were followed from 24 to 28 weeks of pregnancy up to 11 years of age. Maternal self-reports of prenatal NLEs were collected immediately after birth, then analyzed as a cumulative score and by NLEs domain. Children's emotional and behavioral symptoms were assessed at 4 timepoints through the Strengths and Difficulties Questionnaire. RESULTS: Children of mothers exposed to ≥3 NLEs were more likely to follow trajectories of high levels of peer relationship problems (aOR [95 % CI] = 5.69 [1.74-18.69]), emotional symptoms (aOR [95 % CI] = 3.05 [1.08-8.63]), and conduct problems (aOR [95 %] = 3.53 [1.20-10.42]). Among the domains of NLEs, only events related to housing, finance, and living conditions were significantly associated with high emotional and behavioral difficulties trajectories (aOR [95%CI] = 2.71[1.26-5.81]). LIMITATIONS: Potential attrition bias due to a higher dropout rate for children experiencing early indications of emotional and behavioral difficulties. CONCLUSION: Findings support the relationship between prenatal NLEs and child outcomes, underscoring the importance of assessing prenatal stressors across life domains to identify mothers who might be in need of support.

Stressful life events and prenatal representations of the child.

Caregivers' mental representations of their children can be assessed prenatally and are prospectively associated with later caregiving quality and caregiver-child attachment. Compared to balanced, distorted or disengaged representations are linked to insecure caregiver-child attachments. The present study explored factors (i.e. stressful life experiences and positive experiences) that may be linked to risk for distorted and disengaged representations. We used a brief version of the Prenatal Working Model of the Child Interview in a sample of 298 pregnant people (ages 19 to 45 years; M = 30.83, SD = 5.00) between gestational age 11-38 weeks (M = 23.49, SD = 5.70). A greater number of stressful events across three developmental periods (i.e., lifespan, childhood, and pregnancy) were related to increased odds of distorted, compared to balanced classification. Pregnancy stress had the largest association. Positive experiences from childhood did not buffer the association between stress and representations. Findings highlight the importance of stress on prenatal representations of one's child.

Implementation of COVID-19 vaccination services in prison in six European countries: translating emergency intervention into routine life-course vaccination.

BACKGROUND: Evidence has shown that the risk of transmission of SARS-CoV-2 is much higher in prisons than in the community. The release of the COVID-19 vaccine and the recommendation by WHO to include prisons among priority settings have led to the inclusion of prisons in national COVID-19 vaccination strategies. Evidence on prison health and healthcare services provision is limited and often focuses on a single country or institution due to the multiple challenges of conducting research in prison settings. The present study was done in the framework of the EU-founded project RISE-Vac. It aimed to analyse the best practices and challenges applied in implementing COVID-19 universal vaccination services during the pandemic to support future expansion of routine life course vaccination services for people living in prison (PLP). METHODS: Two online cross-sectional surveys were designed and piloted: survey1 on prison characteristics and (non-COVID-19) immunisation practices; survey2 on the implementation and coverage of COVID-19 vaccination with open-ended questions for thematic analysis. Each RISE-Vac project partner distributed the questionnaire to one or two prisons in their country. Answers were collected from eight European prisons' directors or medical directors between November 2021-May 2022. RESULTS: According to our findings, the implementation modalities of COVID-19 vaccination services in the surveyed prisons were effective in improving PLP vaccination coverage. Strategies for optimal management of the vaccination campaign included: periodic time slot for PLP vaccination; new staff recruitment and task shifting; distribution of informational material both to PLP and prison staff. Key challenges included continuity of care after release, immunisation information system, and vaccine hesitancy. CONCLUSIONS: To the best of our knowledge, this is the first study describing the implementation of COVID-19 vaccination services in European prisons, suggesting that the expansion of vaccination provision in prison is possible. There is no unique solution that will fit every country but commonalities likely to be important in the design and implementation of future vaccination campaigns targeting PLP emerged. Increased availability of vaccination services in prison is not only possible, but feasible and highly desirable, and can contribute to the reduction of health inequalities.

Childhood trauma and hair cortisol response over the year following onset of a chronic life event stressor.

OBJECTIVE: Childhood trauma may contribute to poor lifelong health in part through programming of the HPA-axis response to future life stressors. To date, empirical evidence shows an association of childhood trauma with dysregulation of the HPA-axis and blunted cortisol reactivity to acute stressors. Here, we conduct an initial examination of childhood trauma as a moderator of changes over time in perceived stress levels and HPA-axis response to a major chronic stressor in adulthood. METHODS: Participants were 83 maternal caregivers of children newly diagnosed with cancer who completed the Childhood Trauma Questionnaire (CTQ), and who, over the year following their child's cancer diagnosis, had hair samples collected up to 7 times for the assessment of cortisol and completed monthly measures of perceived stress. RESULTS: CTQ scores were in the expected range for a community sample and associated with changes in perceived stress and cortisol concentration over time (γ =.003, p =.002; γ = -.0004, p =.008, respectively) independently of age, education, treatment intensity and randomization to stress management intervention. Maternal caregivers who endorsed lower childhood trauma showed a steeper decline in perceived stress and a larger increase in cortisol levels across the year than caregivers who recalled more childhood trauma. CONCLUSIONS: Findings extend animal models and studies that examine cortisol reactivity to acute stressors and suggest that childhood trauma may program a phenotype that is more psychologically reactive but shows a blunted HPA-axis response to chronic stress. While adaptive in the short-term, this early life programming may incur long-term costs for health. Further work is warranted to examine this possibility.
