RESUMO

BACKGROUND AND OBJECTIVES: A multifaceted construct called occupational communion (OC), defined as a sense of belonging based on social interaction at work, has been proposed to understand why care workers were positively engaged in their jobs over time, even though they were very demanding. Rich qualitative data on the multiple aspects of OC in care work exist, but a valid measure does not. RESEARCH DESIGN AND METHODS: We applied a mixed-method systematic scale development process to measure OC. Aged and dementia care workers in Australia (76%) and other countries participated in a focus group and online surveys (N = 2,451). We also used interview data from our prior study. The study involved 3 components: (1) scale development and design; (2) pilot test validation with exploratory factor analysis; and (3) confirmatory validation via confirmatory factor analysis. The third component assessed convergent and discriminant validity using measures of communion, self-efficacy, work engagement, job and life satisfaction, intention to leave, positive and negative affect, and mood. RESULTS: We developed a 28-item Occupational Communion Scale (OCS) with good internal consistency (composite reliability = 0.75-0.91) across 6 factors: (1) "natural" carer, (2) psychological need to care, (3) connection with clients, (4) connection with coworkers, (5) desire for more connection, and (6) blurred boundaries. All validity measures correlated with OC and work engagement, self-efficacy, and positive affect showed the strongest association. DISCUSSION AND IMPLICATIONS: The OCS can be used to design and evaluate interventions addressing aged care workforce engagement, social connections and well-being, and care outcomes.

RESUMO

Early COVID-19 pandemic data suggested racial/ethnic minority and low-income earning people bore the greatest burden of infection. Structural racism, the reinforcement of racial and ethnic discrimination via policy, provides a framework for understanding disparities in health outcomes like COVID-19 infection. Residential racial and economic segregation is one indicator of structural racism. Little attention has been paid to the relationship of infection to relative overall concentrations of risk (i.e., segregation of the most privileged from the most disadvantaged). We used ordinary least squares and geographically weighted regression models to evaluate the relationship between racial and economic segregation, measured by the Index of Concentration at the Extremes, and COVID-19 cases in Louisiana. We found a significant global association between racial segregation and cumulative COVID-19 case rate in Louisiana and variation across the state during the study period. The northwest and central regions exhibited a strong negative relationship indicating greater risk in areas with high concentrations of Black residents. On the other hand, the southeastern part of the state exhibited more neutral or positive relationships indicating greater risk in areas with high concentrations of White residents. Our findings that the relationship between racial segregation and COVID-19 cases varied within a state further support evidence that social and political determinants, not biological, drive racial disparities. Small area measures and measures of polarization provide localized information better suited to tailoring public health policy according to the dynamics of communities at the census tract level, which may lead to better health outcomes.

RESUMO

OBJECTIVE: Australian aged care workforce surveys offer limited information about those who engage in online dementia education regarding their occupational health and well-being. A salutogenic approach was applied to an aged care context to quantitatively assess both positive and negative aspects of health at work to inform the development of workplace interventions tailored to those interested in self-development. METHODS: Physical, psychological and occupational health were measured in an online cross-sectional survey of general health, chronic conditions, psychological distress, positive and negative affect, job satisfaction, access to workplace amenities and turnover intentions of aged care workers undertaking an online dementia course in October 2014. RESULTS: Participants (N = 662) rated their general physical health as good and a minority experienced chronic conditions such as obesity. Overall, workers had average levels of positive and negative affect and low distress. However, 25% were likely to have a mental health condition. While most were employed on a permanent basis (80%) and reported moderate job satisfaction, 18% were likely to leave their job. There were some gaps in workplace amenities to support health and well-being: for example, 13% reported no access to lunch break areas. CONCLUSIONS: Results suggest precarious resilience in aged care workers enrolled in an Australian online dementia course. Workplace interventions that focus on preventative health strategies are required to address the health risks associated with higher than national averages of obesity and mental health, and reduce exposure of workers to physical and psychological harms.

RESUMO

Brachioplasty, in addition to several nonsurgical interventions (e.g. cryolipolysis, noninvasive radiofrequency, and intense-focused ultrasound) have been described as efficacious in the elimination of excess skin laxity from the upper arms. Recently, fractional CO2 ablation has gained attention for its ability to reduce rhytids and improve skin texture on the face, neck, and hands. In this article, we report the first successful case of fractional CO2 ablation for upper arm contouring.

RESUMO

BACKGROUND: The Self-Image Scale is a self-report measure originally developed for use in women with cancer. Two subscales assess appearance satisfaction (self-acceptance) and perceptions of partners' acceptance of their appearance (partner-acceptance). This study aimed to increase the Self-Image Scale's utility by 1) confirming the two-factor structure of the German version of the Self-Image Scale, 2) testing measurement invariance across sex and age groups and validity, and 3) gathering general population normative data. METHODS: Confirmatory factor analysis methods were used to examine the proposed two-factor model in a random sample of adults from the general German population (N = 1367). Measurement invariance, scale reliability, and validity were assessed. RESULTS: The original factor structure and measurement invariance across sexes and age groups were supported. Women showed significantly lower self-acceptance than men. Adolescent and young adult women showed higher self-acceptance than senior women. For both sexes, partner-acceptance lowered across successive age cohorts. Internal consistencies were good. CONCLUSIONS: Results support the use of the German version of the Self-Image Scale in research and clinical practice. Research directions include validation in further diseases, collecting normative data across countries, and dyadic research, particularly exploring partner-acceptance across the life span.

RESUMO

Female sex is a risk factor for lupus. Sex hormones, sex chromosomes and hormone receptors are implicated in the pathogenic pathways in lupus. Estrogen receptor alpha (ERα) knockout (KO) mice are used for defining hormone receptor effects in lupus. Prior studies of ERα KO in lupus have conflicting results, likely due to sex hormone levels, different lupus strains and different ERα KO constructs. Our objective was to compare a complete KO of ERα vs. the original functional KO of ERα (expressing a short ERα) on disease expression and immune phenotype, while controlling sex hormone levels. We studied female lupus prone NZM2410 WT and ERα mutant mice. All mice (n = 44) were ovariectomized (OVX) for hormonal control. Groups of each genotype were estrogen (E2)-repleted after OVX. We found that OVXed NZM mice expressing the truncated ERα (ERα short) had significantly reduced nephritis and prolonged survival compared to both wildtype and the complete ERαKO (ERα null) mice, but surprisingly only if E2-repleted. ERα null mice were not protected regardless of E2 status. We observed significant differences in splenic B cells and dendritic cells and a decrease in cDC2 (CD11b+CD8-) dendritic cells, without a concomitant decrease in cDC1 (CD11b-CD8a+) cells comparing ERα short to ERα null or WT mice. Our data support a protective role for the ERα short protein. ERα short is similar to an endogenously expressed ERα variant (ERα46). Modulating its expression/activity represents a potential approach for treating female-predominant autoimmune diseases.

RESUMO

Systemic lupus erythematosus (SLE) is a chronic and potentially severe autoimmune disease that disproportionately affects women. Despite a known role for hormonal factors impacting autoimmunity and disease pathogenesis, the specific mechanisms of action remain poorly understood. Our laboratory previously backcrossed "estrogen receptor alpha knockout (ERαKO)" mice onto the NZM2410 lupus prone background to generate NZM/ERαKO mice. This original ERαKO mouse, developed in the mid-1990s and utilized in hundreds of published studies, is not in fact ERα null. They express an N-terminally truncated ERα, and are considered a functional KO. They have physiologic deficiencies including infertility due to disruption of a critical activation domain (AF-1) at the N terminus of ERα, required for most classic estrogen (E2) actions. We demonstrated that female NZM/ERαKO mice had significantly less renal disease and significantly prolonged survival compared to WT littermates despite similar serum levels of autoantibodies and glomerular immune complex deposition. Herein, we present results of experiments using a lupus prone true ERα-/- mice (deletional KO mice on the NZM2410 background), surprisingly finding that these animals were not protected if they were ovariectomized, suggesting that another hormonal component confers protection, possibly testosterone, rather than the absence of the full-length ERα.

RESUMO

INTRODUCTION: Research rarely considers the origin or history of a cancer patient's anxiety and/or depression, instead assuming that these illnesses are related to the cancer experience. The aim of this study was to compare differences in the support needs of people who have experienced anxiety/depression as part of the cancer experience and people who have not, as well as between people who have experienced episodic anxiety/depression and people who have experienced long-term anxiety/depression. METHODS: Twenty-one semi-structured interviews were conducted with people with a current or previous diagnosis of cancer, and a current or previous experience with anxiety and/or depression. Participants were split into four groups based on their history with cancer and anxiety/depression, and an inductive thematic analysis was conducted to identify themes across groups. RESULTS: Two superordinate themes (with three and two subordinate themes respectively) were found: 'coping with cancer' and 'health care system support provision'. Important differences were found across groups, with participants who had a history of anxiety/depression that was unrelated to their cancer diagnosis coping better with the combined burden of cancer and anxiety/depression, experiencing less fear of cancer recurrence, and highlighting more positive hospital and support service related experiences, than those whose anxiety/depression was cancer related. CONCLUSION: The origin and history of a person's anxiety/depression is important to consider when determining how they might cope with cancer, what their support needs are, and how much support they may require.

RESUMO

OBJECTIVE: Cancer and anxiety/depression frequently co-occur, leading to poorer outcomes for these illnesses. However, the majority of existing research investigates how participants view single illnesses alone. This study aimed to explore the content of individuals' multimorbid representations and how these relate to their coping behaviours and self-management strategies for cancer and anxiety/depression. DESIGN: A semi-structured qualitative research design with theoretical thematic analysis. MAIN OUTCOME MEASURES: Multimorbid illness representations, coping behaviours, and self-management strategies. RESULTS: In interviews with 21 participants multimorbid representations varied, three participants viewed cancer and anxiety/depression as unrelated, five participants were uncertain about the relationship between cancer and anxiety/depression, and the majority of participants perceived cancer and anxiety/depression as related. This third group of participants often described relationships as causal, with representations having both positive and negative influences on coping behaviours and self-management strategies. Representations were shown to change over the course of the cancer experience, with fear of cancer recurrence and the influence of participants' most challenging illness also discussed. CONCLUSIONS: People hold multimorbid illness representations that can influence self-management. An awareness of these representations by researchers, health professionals, and patients is important for the creation of future interventions that aim to improve and maintain patient wellbeing.

RESUMO

INTRODUCTION: Legislation making seatbelt use mandatory is considered to have reduced fatal and serious injuries by 25%, with UK government estimates predicting more than 50,000 lives saved since its introduction. However, whilst the widespread use of seatbelts has reduced the incidence of major traumatic injury and death from road-traffic collisions (RTCs), their use has also heralded a range of different injuries. The first ever seatbelt related injury was described in 1956, and since then clear patterns of seatbelt-related injuries have been recognised. METHODOLOGY AND FINDINGS: This review of the published literature demonstrates that the combination of airbags and three-point seatbelts renders no part of the body free from injury. Serious injuries can, and do, occur even when passengers are properly restrained and attending clinicians should have a high index of suspicion for overt or covert intra-abdominal injuries when patients involved in RTCs attend the Emergency Department. Bruising to the trunk and abdomen in a seatbelt distribution is an obvious sign that suggests an increased risk of abdominal and thoracic injury, but bruising may not be apparent and its absence should not be falsely reassuring. A high index of suspicion should be retained for other subtler signs of injury. Children and pregnant women represent high-risk groups who are particularly vulnerable to injuries. CONCLUSION: In this review we highlight the common patterns of seatbelt-related injuries. A greater awareness of the type of injuries caused by seatbelt use will help clinicians to identify and treat overt and covert injuries earlier, and help reduce the rates of morbidity and mortality following RTCs.

RESUMO

Plasmacytoid dendritic cells (pDCs) and their production of type I interferons (IFN) are key pathogenic mediators of systemic lupus erythematosus (SLE). Despite the key role of pDCs in SLE, the mechanism by which pDCs promote disease is not well understood. The first objective for this study was to assess the number and maturation state of pDCs in pre-disease NZM2410 lupus prone mice compared to control mice. Second, we sought to identify mechanisms responsible for the alteration in pDCs in NZM mice prior to onset of clinical disease. We compared the number and percent of pDCs in the spleens and bone marrow (BM) of pre-disease NZM24010 (NZM) mice to C57BL/6 (B6) control mice. In the spleens of pre-disease NZM mice, pDC percent and number were increased. This increase occurs in parallel with a decrease in BM pDC number and percent in the NZM mice. The decrease in BM pDC number suggests the increase in spleen pDCs is a result of altered pDC distribution and not increased production of pDCs in the BM. To determine if pDC developmental potential is altered in lupus prone mice, we cultured BM from NZM and B6 mice in vitro. We found a reduced percentage/number of pDCs developing from the BM of NZM mice compared to B6 mice, which further supports that the increase in pDC number is a result of altered pDC distribution rather than increased pDC production. To better characterize the pDC population, we compared the percentage of mature pDCs in the spleens and BM of NZM mice to controls. In the NZM mice, there is a dramatic reduction in the number of mature pDCs in the BM of NZM mice, suggesting that mature pDCs exit the BM at a higher rate/earlier maturation time compared to healthy mice. We conclude that pDCs contribution to disease pathogenesis in NZM mice may include the alteration of pDC distribution to increase the number of pDCs in the spleen prior to disease onset.

RESUMO

OBJECTIVE: Cancer is associated with negative health and emotional outcomes in those affected by it, suggesting the need to better understand the psychosocial determinants of illness outcomes and coping. The common sense model is the leading psychological model of self-regulation in the face of illness and assumes that subjective illness representations explain how people attempt to cope with illness. This systematic review and meta-analysis examines the associations of the common sense model's illness representation dimensions with health and coping outcomes in people with cancer. METHODS: A systematic literature search located 54 studies fulfilling the inclusion criteria, with 38 providing sufficient data for meta-analysis. A narrative review of the remaining studies was also conducted. RESULTS: Random-effects models revealed small to moderate effect sizes (Fisher Z) for the relations between illness representations and coping behaviors (in particular between control perceptions, problem-focused coping, and cognitive reappraisal) and moderate to large effect sizes between illness representations and illness outcomes (in particular between identity, consequences, emotional representations, and psychological distress). The narrative review of studies with insufficient data provided similar results. CONCLUSIONS: The results indicate how illness representations relate to illness outcomes in people with cancer. However, more high-quality studies are needed to examine causal effects of illness representations on coping and outcomes. High heterogeneity indicates potential moderators of the relationships between illness representations and health and coping outcomes, including diagnostic, prognostic, and treatment-related variables. This review can inform the design of interventions to improve coping strategies and mental health outcomes in people with cancer.

RESUMO

Ninety percent of those diagnosed with systemic lupus erythematosus are female, with peak incidence between the ages of 15 and 45, when women are most hormonally active. Despite significant research effort, the mechanisms underlying this sex bias remain unclear. We previously showed that a functional knockout of estrogen receptor alpha (ERα) resulted in significantly reduced renal disease and increased survival in murine lupus. Dendritic cell (DC) development, which requires both estrogen and ERα, is impacted, as is activation status and cytokine production. Since both estrogen and testosterone levels have immunomodulating effects, we presently studied the phenotype of NZM2410 lupus-prone mice following post- and prepubertal ovariectomy (OVX) ± estradiol (E2) replacement to determine the impact of hormonal status on disease expression and DC development in these mice. We observed a trend toward survival benefit in addition to decreased proteinuria and improved renal histology in the early OVX, but not late OVX- or E2-repleted WT mice. Interestingly, there was also a significant difference in splenic DC subsets by flow cytometry. Spleens from NZM mice OVX'd early had a significant decrease in proinflammatory CD11c+CD11b+ DCs (vs. unmanipulated WTs, late OVX- and E2-repleted mice). These early OVX'd animals also had a significant increase in tolerogenic CD11c+CD8a+ DCs vs. WT. These data join a growing body of evidence that supports a role for hormone modulation of DCs that likely impacts the penetrance and severity of autoimmune diseases, such as lupus.

RESUMO

BACKGROUND: Research on workforce development for high-quality dementia care more often focuses on enhancing employee knowledge and skill and less on managing employee stress and coping at work. OBJECTIVE: To review employee stress and coping in response to high job demands in community-based dementia care organizations in Tasmania, Australia. METHODS: Stress and coping in response to job roles of 25 community-based dementia care workers were reviewed using self-report questionnaire data. Data were analysed for descriptive results and at an individual case level. Individual participant scores were reviewed for clinically significant stress and coping factors to create worker profiles of adjustment. RESULTS: Two adjustment profiles were found. The 'global resilience' profile, where workers showed positive adjustment and resilience indicating they found their jobs highly rewarding, were very confident in their abilities at work and had a strong match between their personal and organizational values. The second 'isolated distress' profile was only found in a minority and included poor opportunities for job advancement, a missmatch in personal and work values or clinically high levels of psychological distress. CONCLUSION: Aged care workplaces that advocate employee well-being and support employees to cope with their work roles may be more likely to retain motivated and committed staff. Future research should consider employee stress and coping at the workforce level, and how this can influence high-quality care delivery by applying the measures identified for this study. Comparative research across different care settings using meta-analytic studies may then be possible.

RESUMO

BACKGROUND: Face-to-face delivery of CBT is not always optimal or practical for informal dementia carers (DCs). Technology-based formats of CBT delivery (TB-CBT) have been developed with the aim to improve client engagement and accessibility, and lower delivery costs, and offers potential benefits for DCs. However, research of TB-CBT for DCs has maintained heavy reliance on therapist involvement. The efficacy of pure TB-CBT interventions for DCs is not currently established Methods: A systematic review of trials of pure TB-CBT intervention for DCs from 1995 was conducted. PsycINFO, Cochrane Reviews, Scopus and MedLine databases were searched using key terms related to CBT, carers and dementia. Four hundred and forty two articles were identified, and inclusion/exclusion criteria were applied; studies were only retained if quantitative data was available, and there was no active therapist contact. Four articles were retained; two randomized and two waitlist control trials. Methodological and reporting quality was assessed. Meta-analyses were conducted for the outcome measures of caregiver depression. RESULTS: Meta-analysis revealed small significant post-intervention effects of pure TB-CBT interventions for depression; equivalent to face-to-face interventions. However, there is no evidence regarding long-term efficacy of pure TB-CBT for DCs. The systematic review further identified critical methodological and reporting shortcomings pertaining to these trials Conclusions: Pure TB-CBT interventions may offer a convenient, economical method for delivering psychological interventions to DCs. Future research needs to investigate their long-term efficacy, and consider potential moderating and mediating factors underpinning the mechanisms of effect of these programs. This will help to provide more targeted interventions to this underserviced population.

RESUMO

Female lupus-prone NZM2410 estrogen receptor α (ERα)-deficient mice are protected from renal disease and have prolonged survival compared with wild-type littermates; however, the mechanism of protection is unknown. Plasmacytoid dendritic cells (pDCs) and type I IFN drive lupus pathogenesis. Estrogen acting via ERα enhances both pDC development and IFN production. The objectives for this study were to determine if ERα modulates pDC function and IFN activity in predisease NZM2410 mice as a possible protective mechanism of ERα deficiency in lupus-prone mice. We measured the effect of ERα deficiency on spleen pDC frequency, number, maturation, and activation state. ERα deficiency reduced type I IFN activity and the frequency of MHC class II(+) pDCs in the spleen without altering overall pDC frequency, number, or maturation state. Additionally, ERα-deficient NZM2410 mice had a significantly decreased frequency of pDCs expressing PDC-TREM, a modulator of TLR-mediated IFN production. After in vitro TLR9 stimulation, ERα deficiency significantly reduced the expression of PDC-TREM on pDCs from both NZM2410 and C57BL/6 mice. Thus, we have identified a significant effect of ERα deficiency on pDCs in predisease NZM2410 mice, which may represent a mechanism by which ERα deficiency protects NZM2410 mice from lupuslike disease.

RESUMO

OBJECTIVE: The purpose of the study is to describe from a relational perspective, partners' psychological adjustment, coping and support needs for advanced prostate cancer. DESIGN: A mixed methods design was adopted, employing triangulation of qualitative and quantitative data, to produce dyadic profiles of adjustment for six couples recruited from the urology clinics of local hospitals in Tasmania, Australia. METHODS: Dyads completed a video-taped communication task, semi-structured interview and standardised self-report questionnaires. RESULTS: Themes identified were associated with the dyadic challenges of the disease experience (e.g. relationship intimacy, disease progression and carer burden). Couples with poor psychological adjustment profiles had both clinical and global locus of distress, treatment side-effects, carer burden and poor general health. Resilient couples demonstrated relationship closeness and adaptive cognitive and behavioural coping strategies. The themes informed the adaption of an effective program for couples coping with women's cancers (CanCOPE, to create a program for couples facing advanced prostate cancer (ProCOPE-Adv). CONCLUSION: Mixed method results inform the development of psychological therapy components for couples coping with advanced prostate cancer. The concomitance of co-morbid health problems may have implications for access and engagement for older adult populations in face-to-face intervention.

RESUMO

Farmworkers experience pervasive economic insecurity in part because of the seasonal nature of agricultural work and limited employment protections. Yet little is known about the adequacy of the social safety net in responding to farmworker needs. Using data from the 2005-2009 National Agricultural Workers Survey (N = 10,469), the current study analyzed predictors of social welfare participation among Latinos, who represent approximately 80 percent of all farmworkers. Nearly 95 percent are immigrants, although almost half of them have lived in the United States for more than 10 years. Descriptive analyses showed that, even among farmworker households whose income fell below the poverty line or that were headed by legally documented individuals, social services use was very low. Logistic regression analyses revealed that degree of social integration influenced social welfare participation, controlling for education, poverty status, family composition, and employment characteristics. Latino farmworkers who were recent immigrants (that is, in the United States for less than five years) had significantly lower odds of access to social insurance and public assistance programs relative to their U.S.-born counterparts. Low self-reported English ability significantly decreased access to most social insurance programs but not public assistance receipt. The findings indicate the need for social workers to engage in outreach efforts and policy advocacy to improve farmworkers access to social welfare.
