RESUMO

PURPOSE: Social support is a crucial protective factor against psychological concerns in patients with cancer. However, there is limited knowledge regarding the differential impacts of social support on cancer worries and depressive symptoms in patients undergoing genetic counseling for hereditary cancer. The current study utilized a high-volume database from a multi-site cancer genetics clinic to assess the impact of perceived social support on depressive symptoms and cancer worries among patients of different age groups (young versus older patients) and diagnosis status (diagnosed survivors versus undiagnosed). METHODS: 6,666 patients completed brief assessments of depressive symptoms, cancer worries, social support, and demographic questionnaires as part of routine clinical care between October 2016 and October 2020. Logistics and moderated regression were used to analyze the relationships between social support, depressive symptoms, and cancer worries. RESULTS: Increased social support was associated with fewer depressive symptoms and fewer cancer worries across all patients. Social support mitigated depressive symptoms most significantly for young adult patients with and without cancer. Social support mitigated cancer worries most significantly for young adults with cancer and older adults without cancer. CONCLUSIONS: While results were mixed, general findings upheld original hypotheses. Social support buffered depressive symptoms and cancer worries differentially for patients of different ages and different disease status. IMPLICATIONS FOR CANCER SURVIVORS: Social support groups are beneficial for all patients and should be emphasized by cancer clinics. However, increasing patient-tailored and age-appropriate support networks will be crucial for managing depression and cancer worries for high-risk survivors: young adults with cancer.

RESUMO

Recent evidence suggests that protecting human amnion and chorion matrices (HACM) during processing enhances the performance of HACM for wound repair and tissue regeneration. We utilised a diabetic (db/db) delayed wound healing mouse model. Treatment of db/db full-thickness excisional wounds with HACM, processed with a polyampholyte preservative accentuated the proliferative phase of wound healing that decreased the time necessary to heal wounds. Polyampholyte protection improved the preservation of growth factors and cytokines during room temperature storage following E-beam sterilisation and improved its function in wound healing applications. Our findings indicate protected HACM tissue up-regulated MIP2, NF-kB, TNF-α, KI-67, and Arg1 (0.6-fold to 1.5-fold) but those changes were not statistically significant. Immunofluorescent assessment identifying cell activity illustrated an induction of the proliferative phase of wound healing and a switch from an inflammatory macrophage phenotype (M1) to a pro-regenerative macrophage phenotype (M2a). Genomic profiling of 282 genes was performed using Nanostring from co-cultures of human macrophages and fibroblasts. The polyampholyte + HACM-treated group, compared with the HACM or polyampholyte alone groups, had a statistically significant up-regulation (32-368 fold) of 12 genes primarily involved in macrophage plasticity including CLC7, CD209, CD36, HSD11B1, ICAM1, IL1RN, IL3RA, ITGAX, LSP1, and PLXDC2 (adj. p-value < 0.05). The polyampholyte alone group demonstrated statistically significant down-regulation of four genes ADRA2, COL7A1, CSF3, and PTGS2 (adj. p < 0.05). The HACM alone group up-regulated four genes ATG14, CXCL11, DNMT3A, and THBD, but the results were not statistically significant. Biomechanical measurements indicated that wounds treated with polyampholyte-protected HACM had more tensile integrity compared with wounds treated with HACM alone. These findings indicate that better protection of HACM during processing stabilises the HACM matrix, which may lead to improved wound healing outcomes.

RESUMO

Limited research has explored depression and cancer worries (CWs) among adolescents and young adults with cancer (AYAs) seeking genetic counseling. This study evaluated depressive symptoms and CWs among five groups: AYAs, adolescents and young adults without cancer (AYAWOCs), older adults with cancer (OAs), older adults without cancer (OAWOCs), and older adults diagnosed with cancer in their adolescent and young adult years (OA/AYAs). A retrospective data analysis was performed on 6524 patients, which found that AYAs reported significantly higher depressive symptoms and CWs compared with all other groups except OA/AYAs. These findings suggest that the intersection between age and cancer diagnosis is related to depressive symptoms and CWs.

RESUMO

BACKGROUND: Anxiety disorders in youth are frequently underdiagnosed and untreated, partly due to a lack of screening in primary care. The Generalized Anxiety Disorder 7-item (GAD-7) scale is a brief self-report measure designed to screen for anxiety in primary care settings. However, little is known about the psychometrics of this scale with adolescents. METHODS: Participants included 579 youth age 11 to 17 years who received screening for depression in a primary care setting through a web-based application, VitalSign6, over a 4-year period. Psychometric analyses were completed based on classical test theory (CTT) and item response theory (IRT). RESULTS: Using CTT and IRT methods, the GAD-7 has a unidimensional structure with good psychometric properties. In addition, the IRT analysis demonstrates that items 1 and 2 are strongly associated with the total score, and thus are good choices as a 2-item screening tool. Convergent validity was demonstrated, with high correlations between the GAD-7 and other measures of anxiety, and discriminant validity was also demonstrated, with low correlations to measures of other psychological states. CONCLUSIONS: This psychometric evaluation of the GAD-7 provides support for the utility of this measure with adolescents. The GAD-2 is a good estimate of GAD-7 total score.

RESUMO

OBJECTIVE: Justice-involved veteran research remains largely limited to men and those using Veterans Health Administration (VHA) services. Research inclusive of women and those not using VHA care is critical to understanding mental health and suicide risk among justice-involved veterans. This study examined whether lifetime justice involvement was associated with symptoms of posttraumatic stress disorder (PTSD) and depression, recent suicidal ideation, and lifetime suicide attempt. METHOD: We conducted a secondary analysis of 812 post-9/11 male and female veterans. The sample included veterans eligible and not eligible for VHA care. Participants were administered the PTSD Checklist for DSM-IV, the Patient Health Questionnaire-8, and the Columbia-Suicide Severity Rating Scale. Additional questions assessed justice involvement, military characteristics, demographics, and recent use of VHA mental health care. RESULTS: History of justice involvement was associated with more severe PTSD and depression symptoms as well as suicidal ideation and suicide attempt. Associations were maintained after adjusting for sex, combat exposure, service branch, recent use of VHA mental health care, and education. Sex-stratified exploratory analyses revealed consistent findings among males; justice involvement was associated with suicide attempt among females. Current probation or parole was particularly related to depressive symptoms, suicidal ideation, and suicide attempt. CONCLUSIONS: Justice-involved veterans appear to be a vulnerable population experiencing heightened psychiatric symptoms and increased risk for recent suicidal ideation and lifetime suicide attempt. Programs within VHA and the community are important for connecting justice-involved veterans to mental health services and mitigating suicide risk.

RESUMO

Objective : This study evaluates the effects of time incarcerated on employment outcomes between a manualized vocational program, the About Face Vocational Program (AFVP), and a hybrid program of the AFVP and Individualized Placement and Support, Supported Employment (AFVP + IPS-SE). Method : Eighty-four veterans with the histories of felony convictions and a mental illness or a substance use disorder were randomly assigned to the AFVP or AFVP + IPS-SE conditions and followed for 6 months. The associations between time to employment and months incarcerated were evaluated using nonparametric tests. Findings : The number of months incarcerated was positively associated with time to employment in the hybrid AFVP + IPS-SE condition but not the AFVP condition. In addition, significant differences were found between employment rates of the groups at lower number of months incarcerated, with higher rates of employment in the hybrid AFVP + IPS-SE condition, becoming similar as months incarcerated increased. Conclusion and Implications for Practice : Number of months incarcerated may have a deleterious effect on employment rates when using IPS-SE.

RESUMO

This study examined clergy's use of 15 suicide prevention competencies. Four hundred ninety-eight U.S. Catholic, Jewish, and Protestant clergy responded to an online survey regarding their use of these competencies. Analysis of variance, backward stepwise regression, and principal components analysis were used to determine clergy group differences, predictors of use of competencies, and a parsimonious summary of competencies. Some respondents reported infrequent opportunities to develop these competencies. Respondents reported using general pastoral competencies more than suicide-specific competencies. Protestant clergy reported that their congregants watch over each other significantly more than Jewish clergy. Catholic and Jewish clergy reported significantly more competence in conducting suicide funerals than Protestant clergy. Contacts by suicidal people and number of hours of suicide-specific training predicted the use of more competencies. Competency components included postvention following a suicide, nonjudgmental attitudes, talking with a suicidal person, and pastoral care. Findings suggest that clergy may benefit from consultation and suicide-specific training.

RESUMO

Debridement of the bone surface during a surgical fusion procedure initiates an injury response promoting a healing cascade of molecular mediators released over time. Autologous grafts offer natural scaffolding to fill the bone void and to provide local bone cells. Commercial bone grafting products such as allografts, synthetic bone mineral products, etc., are used to supplement or to replace autologous grafts by supporting osteoinductivity, osteoconductivity, and osteogenesis at the surgical site. To assure osteogenic potential, preservation of allogeneic cells with cryoprotectants has been developed to allow for long-term storage and thus delivery of viable bone cells to the surgical site. Dimethyl sulfoxide (DMSO) is an intracellular cryoprotectant commonly used because it provides good viability of the cells post-thaw. However, there is known cytotoxicity reported for DMSO when cells are stored above cryogenic temperatures. For most cellular bone graft products, the cryoprotectant is incorporated with the cells into the other mineralized bone and demineralized bone components. During thawing, the DMSO may not be sufficiently removed from allograft products compared to its use in a cell suspension where removal by washing and centrifugation is available. Therefore, both the allogeneic cell types in the bone grafting product and the local cell types at the bone grafting site could be affected as cytotoxicity varies by cell type and by DMSO content according to reported studies. Overcoming cytotoxicity may be an additional challenge in the formation of bone at a wound or surgical site. Other extracellular cryoprotectants have been explored as alternatives to DMSO which preserve without entering the cell membrane, thereby providing good cellular viability post-thaw and might abrogate the cytotoxicity concerns.

RESUMO

Advances in middle infrared technology are leading researchers beyond the Fourier transform infrared spectrometer and to the quantum cascade laser. While most research focuses on gas-phase detection, recent research explores its use for condensed-phase matter studies. This work investigates its use for monitoring biologically relevant samples of glucose in serum. Samples with physiological glucose concentrations were monitored with a laser at 1036 cm-1. A 0.992 R2 linearity value was observed. In addition, using another laser at 1194 cm-1 as a measure of the background spectroscopic characteristics, a linearity of 0.998 R2 was observed. The average predictive standard errors of the mean (SEM) were 32.5 and 24.7 mg/dL, respectively, for each method. Quantum cascade lasers could be used to develop middle infrared devices for uses beyond the confines of the laboratory.

RESUMO

Evanescent wave cavity ring-down spectroscopy (EW-CRDS) is used to observe the adsorption isotherm for hemoglobin (Hb) from controlled urine samples to assess the potential for rapid diagnosis in hemoglobinuria. The absorbance of Hb at 425 nm is monitored using an alexandrite laser-pumped, room temperature, LiF:F2+** color-center pulsed laser. A minimum absorbance detection level of 2.57 x 10(-4) is achieved, corresponding to a minimum detectable concentration of Hb in urea of 5.8 nM. A multilayered Hb biofilm is formed, and a minimum of eight layers are required to model the adsorption isotherm, allowing for cooperative binding within the layers and extending 56 nm into the interface. A binding constant for Hb to silica 18.23+/-7.58 x 10(6) M is derived, and a binding constant for Hb to Hb in subsequent layers is determined to be 5.631+/-0.432 x 10(5) M. Stoichiometric binding coefficients of 1.530+/-0.981 for layer one and 1.792+/-0.162 for subsequent layers suggest that cooperative binding both to the silica surface and between the layers of the biofilm is important.
