RESUMO

PURPOSE: Sexual health is important for quality of life among older (≥65 years) cancer survivors. Yet, little is known about the extent to which their sexual health has been studied. METHODS: In this integrative review, PubMed, PsycINFO, CINAHL, and Web of Science were searched for data-based articles of sexual health among older cancer survivors. Using a matrix, study characteristics, including cancer types and areas of sexual health, were categorized. RESULTS: The sample included 82 articles (81 studies). The areas of sexual health were categorized into sexual function, body image, sexual function-related distress, sexual health-related quality of life, sexual activity, sexual enjoyment, and sexual desire. Most targeted prostate cancer (n = 56, 69.1%) and studied sexual function, e.g., erectile function (n = 53, 94.6%). Body image (n = 16, 19.8%) was next frequently studied, targeting women with breast cancer. Measures to assess areas of sexual health, largely unstandardized, varied widely. Generally, older cancer survivors reported negative changes in sexual function and other areas during and after cancer treatment. CONCLUSIONS: Studies of sexual health among older cancer survivors have been focused primarily on prostate cancer, male, and sexual function. Together with the lack of standardized sexual health measures validated for older adults, this narrow research focus contributes to the limited body of knowledge regarding sexual health among older cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: Given that cancer and cancer treatment affect both men and women and many aspects of sexual health beyond functioning, broadening the scope of sexual health and cancer type is warranted for future research.

RESUMO

CONTEXT: Whether a largescale disaster alters people's previous decisions about their end-of-life care is unknown. OBJECTIVES: We examined the effects of a disaster, the COVID-19 pandemic, on stability of end-of-life care preferences among dialysis patients and on patient-surrogate goals-of-care congruence. METHODS: We used a natural experimental design to examine goals-of-care preferences pre- and postexposure to the pandemic during a pragmatic trial testing SPIRIT (sharing patient's illness representations to increase trust), an evidence-based advance care planning (ACP) intervention. There were 151 patient-surrogate dyads who prior to the pandemic lockdown had completed baseline (T1) and postintervention assessments (T2) regarding their goals-of-care preferences in two end-of-life scenarios. Of those 151 dyads, 59 intervention, and 51 usual care dyads consented to be in the present study and completed the goals-of-care tool two additional times, at enrollment (T3) and six months later (T4), along with the COVID stress scale (CSS). Dyad congruence was ascertained by comparing patient and surrogate responses to the goals-of-care tool. RESULTS: There were no changes over time in the proportions of patients who chose comfort-care-only in the goals-of-care tool. The proportion of patients who chose comfort-care-only and dyad congruence were higher in SPIRIT compared to usual care, but there was no interaction between that treatment effect and exposure to the pandemic. CSS was associated with neither patients' preferences nor dyad congruence. CONCLUSIONS: The pandemic alone did not appear to influence patients' goals-of-care preferences or dyad congruence. This finding supports the stability of value-based end-of-life preferences in general, even during a disaster.

RESUMO

CONTEXT: Reliable and valid measures are critical in accurately assessing outcomes of advance care planning interventions (ACP) for end-of-life (EOL) decision-making. OBJECTIVES: To develop measures of preparedness for EOL decision-making for patients with end-stage renal disease and their surrogates (an exemplar population). METHODS: In this 3-phase study, Phases 1 and 2 included a cross-discipline concept analysis of the preparedness construct, item generation for patient and surrogate scales (82 items), evaluation of content validity and readability, cognitive interviewing, and item reduction. In phase 3, the retained 26 patient and 25 surrogate items were administered to 426 patients and 426 surrogates during a multisite trial of an ACP intervention versus care-as-usual and evaluated internal consistency, 2-week test-retest reliability, and construct validity. RESULTS: Scales were reduced to 20 patient and 19 surrogate items during phase 3. Cronbach's alphas were 0.86 (patient) and 0.90 (surrogate). There was a strong correlation between preparedness at baseline and two weeks for both scales (r = 0.66-0.69, P < 0.001). Confirmatory factor analysis and item-response analyses suggested unidimensionality. A significant correlation was shown between patient preparedness and patient decisional conflict (r = -0.53, P < 0.001), and surrogate preparedness and surrogate decision-making confidence (r = 0.44, P < 0.001). Among those who received the ACP intervention, the effect size of change was medium: Cohen's d = 0.54, P < 0.001 for patients and d = 0.57, P < 0.001 for surrogates. CONCLUSIONS: The preparedness scales demonstrated strong psychometric properties. Future studies should examine scale performance in other populations.

RESUMO

Biopolymers have the utmost significance in biomedical applications and blending synthetic polymers has shown favorable characteristics versus individual counterparts. The utilization of the blends can be restricted through the use of toxic chemical agents such as initiators or crosslinkers. In this regard, a chemical agent-free ionizing irradiation is a beneficial alternative for preparing the hydrogels for biomedical applications. In this study, carboxymethyl chitosan (CM-CS), guar gum (GG), and poly(vinylpyrrolidone) (PVP) based ternary blends (TB) were crosslinked using various doses of ionizing irradiation to fabricate hydrogels. The prepared hydrogels were characterized for physicochemical properties, swelling analysis, biological assays, and drug delivery applications. Swelling analysis in distilled water revealed that the hydrogels exhibit excellent swelling characteristics. An in vitro cytocompatibility assay showed that the hydrogels have greater than 90% cell viability for the human epithelial cell line and a decreasing cell viability trend for the human alveolar adenocarcinoma cell line. In addition, the prepared hydrogels possessed excellent antibacterial characteristics against gram-positive Staphylococcus aureus (S. aureus) and gram-negative Escherichia coli (E. coli). Finally, the release studies of anti-inflammatory Quercus acutissima (QA) loaded hydrogels exhibited more than 80% release in phosphate-buffered saline (pH = 7.4). These findings suggest that TB hydrogels can be used as suitable carrier media for different release systems and biomedical applications.

RESUMO

Importance: Evidence of effectiveness of advance care planning (ACP) strategies for patients receiving dialysis and their families is needed. Objectives: To test the effectiveness of an ACP intervention to prepare patients and their surrogates for end-of-life (EOL) decision-making and to improve surrogate bereavement outcomes. Design, Setting, and Participants: This cluster randomized clinical trial, An Effectiveness-Implementation Trial of SPIRIT (Sharing Patients' Illness Representations to Increase Trust) in ESRD, was conducted from December 2017 to March 2023 and included 42 dialysis clinics in 5 US states (Georgia, New Mexico, North Carolina, Pennsylvania, and Virginia) randomized to provide intervention or usual care. Recruitment was from February 15, 2018, to January 31, 2022, and patient-surrogate dyads were followed up for 21 months (until January 17, 2023) or until patient death. Intervention: Each clinic selected 1 or 2 health care workers (eg, nurse practitioner, registered nurse, or social worker) to conduct 45- to 60-minute ACP discussions with dyads in the clinic or remotely. After March 13, 2020 (commencement of the COVID-19 emergency declaration), all discussions were conducted remotely. An ACP summary was placed in patients' medical records. Main Outcomes and Measures: The primary, 2-week preparedness outcomes were dyad congruence on EOL goals of care, patient decisional conflict, surrogate decision-making confidence, and a composite of dyad congruence and surrogate decision-making confidence. Secondary bereavement outcomes were anxiety, depression, and posttraumatic distress 3 months after patient death. To adjust for COVID-19 pandemic effects on bereavement outcomes, a variable to indicate the timing of baseline and 3-month assessment relative to the COVID-19 emergency declaration was created. Results: Of the 426 dyads enrolled, 231 were in the intervention clinics, and 195 were in the control clinics. Among all dyads, the mean (SD) patient age was 61.9 (12.7) years, and the mean (SD) surrogate age was 53.7 (15.4) years. At 2 weeks, after adjusting for baseline values, dyad congruence (odds ratio [OR], 1.61; 95% CI, 1.12-2.31; P = .001), decisional conflict scores (ß, -0.10; 95% CI, -0.13 to -0.07; P < .001), and the composite (OR, 1.57; 95% CI, 1.06-2.34; P = .03) were higher in the intervention group than in the control group. Surrogate decision-making confidence was similar between groups (ß, 0.06; 95% CI, -0.01 to 0.13; P = .12). Among 77 bereaved surrogates, after adjusting for baseline values and assessment timing, intervention group anxiety was lower than control group anxiety (ß, -1.55; 95% CI, -3.08 to -0.01; P = .05); however, depression (ß, -0.18; 95% CI, -2.09 to 1.73; P = .84) and posttraumatic distress (ß, -0.96; 95% CI, -7.39 to 5.46; P = .75) were similar. Conclusions and Relevance: In this randomized clinical trial, the ACP intervention implemented by health care workers at dialysis centers improved preparation for EOL decision-making but showed mixed effectiveness on bereavement outcomes. The ACP intervention implemented in dialysis centers may be an effective strategy to the dyad preparation for end-of-life care as opposed to the current focus on advance directives.
