Unconventional use of ablative fractional photothermolysis in arm contouring.

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.

Novel mechanism for estrogen receptor alpha modulation of murine lupus.

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.

Complete knockout of estrogen receptor alpha is not directly protective in murine lupus.

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.

Plasmacytoid dendritic cell distribution and maturation are altered in lupus prone mice prior to the onset of clinical disease.

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.

Illness representations, coping, and illness outcomes in people with cancer: a systematic review and meta-analysis.

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.

Estrogen Receptor α Deficiency Modulates TLR Ligand-Mediated PDC-TREM Expression in Plasmacytoid Dendritic Cells in Lupus-Prone Mice.

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.

We are not all coping: a cross-sectional investigation of resilience in the dementia care workforce.

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.

Caring for the carer: a systematic review of pure technology-based cognitive behavioral therapy (TB-CBT) interventions for dementia carers.

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.

Perspectives of the community-based dementia care workforce: "occupational communion" a key finding from the Work 4 Dementia Project.

BACKGROUND: Community care workers' experience of delivering support to people with dementia is less researched than that of residential workers. The purpose of the study is to explore community-based dementia care workers' perspectives about their roles and the contextual variables that impact upon their work experiences. METHOD: A qualitative design was employed. Twenty-five community dementia care workers (average age 53 years, majority female and employed casually) participated in standardized semi-structured interviews about their job roles, training, employer agenda, organizational support, and intention to stay. A deductive approach to Interpretive Phenomenological Analysis was adopted to identify key themes. RESULTS: Three themes highlighted workers' experiences. Occupational communion described strong attachment to clients and a desire for greater connection with colleagues. Job demands described the challenges of work, which varied with intensity. Job resources ranged from positive (strong organizational commitment) to negative (poor pay and conditions). Occupational communion was identified as a concept that exists at the interface between social and organization psychology that was perceived to be essential for adaptive coping. Identifying themes informed a conceptual model for designing intervention components aimed at improving workers' skills, capabilities, and employer supportive functions. CONCLUSION: Occupational communion may be particularly relevant for women's caring careers and future research is needed to explore the relevance of this concept for men. To determine reliable change associated with interventions that target occupational communion, further investigation is required in relation to measurement approaches.

Psychosocial factors in adults with chronic kidney disease: characteristics of pilot participants in the Tasmanian Chronic Kidney Disease study.

BACKGROUND: Psychosocial factors including depression, anxiety and lower social support are common in patients with chronic kidney disease (CKD). However the influence of these potentially modifiable risk factors on morbidity and mortality in this renal population is unknown. The Tasmanian Chronic Kidney Disease study is a prospective cohort study which aims to examine the influence of both biomedical and psychosocial factors on disease progression, decision making and length and quality of life in adults with severe CKD, prior to kidney replacement therapy (KRT). This paper describes the recruitment, baseline characteristics and initial follow-up of pilot participants. METHODS: Adults aged > 18 years with stage 4 CKD (eGFR 15-29 mls/min/1.73 m2) and not receiving dialysis were recruited via treating physicians. Measures included depression (9-item Patient Health Questionnaire), anxiety (Beck Anxiety Inventory) and social support (Multidimensional Scale of Perceived Social Support). Primary outcomes were kidney disease progression, use of KRT and health-related quality of life (Kidney Disease and Quality of Life Short Form and the EQ-5D). RESULTS: Of those invited (n = 105), 49 provided consent and completed baseline assessment. There were no significant differences between responders and non-responders in age, gender and socio-economic status (all p > 0.05). Participants were predominantly male (63.3%) with a mean age of 72.6 ± 10.2 years. Mean serum creatinine was 241 ± 62 µmol/L with mean eGFR 22 ± 5 mls/min/1.73 m2. Prevalence of major depression and moderate to severe anxiety was 10% and 9% respectively. Less severe depression and fewer anxiety symptoms were associated with higher health-related quality of life. Follow-up at 10-months showed CKD progression in 34% of participants (use of KRT in 16%, stage 5 CKD without KRT in 18%), one death, with the remainder stable at CKD stage 3 or 4. CONCLUSIONS: Results indicate that a larger prospective study is feasible and has the capacity to examine the influence of biomedical and psychosocial factors on kidney disease progression, use of dialysis and transplantation, and salient personal and economic outcomes. Findings have the potential to provide an evidence base for revising healthcare provision in order to optimize the care of patients with CKD.

Place, Race, and Case: Examining Racialized Economic Segregation and COVID-19 in Louisiana.

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.

The precarious resilience of aged care employees enrolled in an Australian online dementia course: A cross-sectional study of occupational health and well-being.

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.

Developing the Occupational Communion Scale: Belonging-Based Social Connections Are Vital for Work Engagement, Self-Efficacy, and Positive Affect in Aged Care Workforces.

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.

Estrogen receptor alpha modulates Toll-like receptor signaling in murine lupus.

Systemic lupus erythematosus (SLE) is a disease that disproportionately affects females. Despite significant research effort, the mechanisms underlying the female predominance in this disease are largely unknown. Previously, we showed that estrogen receptor alpha knockout (ERαKO) lupus prone female mice had significantly less pathologic renal disease and proteinuria, and significantly prolonged survival. Since autoantibody levels and number and percentage of B/T cells were not significantly impacted by ERα genotype, we hypothesized that the primary benefit of ERα deficiency in lupus nephritis was via modulation of the innate immune response. Using BMDCs and spleen cells/B cells from female wild-type or ERαKO mice, we found that ERαKO-derived cells have a significantly reduced inflammatory response after stimulation with TLR agonists. Our results indicate that the inflammatory response to TLR ligands is significantly impacted by the presence of ERα despite the absence of estradiol, and may partially explain the protective effect of ERα deficiency in lupus-prone animals.

Posttraumatic growth after cancer: the importance of health-related benefits and newfound compassion for others.

PURPOSE: There is growing evidence in psycho-oncology that people can experience posttraumatic growth (PTG), or positive life change, in addition to the distress that may occur after a cancer diagnosis. Many studies utilise existing PTG measures that were designed for general trauma experiences, such as the Posttraumatic Growth Inventory. However, such inventories may not take into account life changes associated with a crisis specifically in a health-related context. METHOD: The current study presents a mixed method exploration of the post-diagnosis experience of cancer survivors (N = 209) approximately 3 years after diagnosis. RESULTS: Quantitative and qualitative assessment of PTG showed that appreciating life was the most salient area of positive life change for cancer survivors. The results also revealed that in addition to several PTG domains captured by existing quantitative PTG measures, further positive life changes were reported, including compassion for others and health-related life changes. CONCLUSIONS: These domains of PTG highlight the unique context of a cancer diagnosis and the potential underestimation of positive life change by existing inventories. Further research is warranted that is directed towards designing a context-specific PTG measure for cancer survivors.

Building capacity and resilience in the dementia care workforce: a systematic review of interventions targeting worker and organizational outcomes.

BACKGROUND: Dementia increasingly impacts every health and social care system in the world. Preparing the dementia care workforce is therefore paramount, particularly in light of existing problems of staff retention and turnover. Training interventions will need to increase worker and organizational capacity to deliver effective patient care. It is not clear which training interventions best enhance workers' capacity. A review of the evidence for dementia care training interventions to enhance worker capacity and facilitate organizational change is presented. METHODS: A systematic literature review was conducted. All selected randomized intervention studies aimed to enhance some aspect of dementia care worker or workforce capacity such as knowledge of dementia, psychological well-being, work performance, and organizational factors such as retention or service delivery in dementia care. RESULTS: Seventy-four relevant studies were identified, but only six met inclusion criteria for the review. The six studies selected focused on worker and organizational outcomes in dementia care. All interventions were multi-component with dementia education or instructional training most commonly adopted. No interventions were found for the community setting. Variable effects were found for intervention outcomes and methodological concerns are raised. CONCLUSION: The rigor of scientific research in training interventions that aim to build capacity of dementia care workers is poor and a strong need exists for evaluation and delivery of such interventions in the community sphere. Wider domains of interest such as worker psychological health and well-being need to be examined further, to understand capacity-building in the dementia care workforce.

Individual and dyadic predictors of body image in women with breast cancer.

OBJECTIVE: Previous studies examining the body image among breast cancer (BC) patients have primarily focused on their psychosocial adjustment or on the predictive value of body image on quality of life. Little is known about predictors of body image. METHODS: The present study investigated how much body image in women with BC is determined by individual factors (surgery type, medical treatments, disease stage, women's age, depressive symptoms) and by dyadic variables (relationship satisfaction and duration, dyadic coping). Furthermore, two different aspects of women's body image were assessed: self- acceptance and perceptions of partners' acceptance. Ninety-eight German women with early stage BC and their partners participated. RESULTS: Individual and dyadic aspects of body image were differentially related to body image. Women's depressive symptoms and men's marital satisfaction predicted women's self-acceptance, but not women's perceptions of their partners' acceptance of their appearance. Female's relationship satisfaction and perspective on common dyadic coping predicted women's perceptions of their partner's acceptance of their appearance. CONCLUSIONS: The findings suggest interventions that include strategies to reduce women's depressive symptoms and build relationship satisfaction, might reduce body image difficulties in women after BC.

Psychometric properties of the German version of the Self-Image Scale (SIS-D).

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.

A couple-based intervention for female breast cancer.

OBJECTIVE: Although women's breast cancer affects both women and their male partners, as well as their relationships, few interventions have been developed to work with couples confronting breast cancer. The current investigation presents the pilot results from a new couple-based intervention program for breast cancer that teaches couples how to minimize negative effects and maximize positive functioning during this difficult time. METHOD: In this pilot study, 14 couples in which the wife had early stage breast cancer were randomly assigned to one of the two treatment conditions: Couple-based relationship enhancement (RE) or treatment-as-usual (TAU). RESULTS: The results from this study suggest that compared with couples receiving treatment-as-usual, both women and men in the RE condition experienced improved functioning on individual psychological variables as well as relationship functioning at posttest and 1-year follow-up. In addition, women in RE show fewer medical symptoms at both time periods. CONCLUSIONS: In this pilot study, the couple-based intervention, RE, has shown promise in improving individual, medical, and relationship functioning for couples in which the woman is facing breast cancer, and therefore merits further investigation on a larger scale.
