Long-Term Second Malignancies in Prostate Cancer Patients Treated With Low-Dose-Rate Brachytherapy and Radical Prostatectomy.

PURPOSE: Second malignancy is a rare but potentially lethal event after prostate brachytherapy, but data remain scarce on its long-term risk. The objective of this study is to estimate the number of pelvic second malignancies following brachytherapy compared to radical prostatectomy (RP). MATERIALS AND METHODS: We retrospectively reviewed patients treated with low-dose 125I brachytherapy and RP in British Columbia from 1999 to 2010. Kaplan-Meier estimates for pelvic (bladder and rectum), invasive pelvic, any second malignancy, and death from any second malignancy were assessed. Cox multivariable analyses were performed adjusting for initial treatment type, age, post-RP adjuvant/salvage external beam radiation therapy status, and smoking history. RESULTS: Two thousand three hundred seventy-eight brachytherapy and 9089 RP patients were included. Median age was 66 years (interquartile range [IQR] 61-71) and 63 years (IQR 58-67), respectively. Median follow-up time to event or censured was 14 years (IQR 11.5-17.3). The Kaplan-Meier estimates for pelvic second malignancy at 15 and 20 years were 6.4% and 9.8%, respectively, after brachytherapy, and 3.2% and 4.2% after RP. Time to any second malignancy and time to death from any second malignancy were not significantly different (P > .05). On Cox multivariable analysis, brachytherapy, compared to surgery, was an independent factor for pelvic (hazard ratio [HR] 1.81 [95% CI 1.45-2.26], P < .001) and invasive pelvic second malignancy (HR 2.13 [95% CI 1.61-2.83], P < .001). Increased age and smoking were also associated with higher estimates of events (P < .001). CONCLUSIONS: After adjustment for age, post-RP adjuvant/salvage external beam radiation therapy status, and smoking status, numerically higher long-term HRs of pelvic and invasive pelvic second malignancy in patients treated with brachytherapy compared to RP were noted.

Perceived control moderates the internalized stigma model of seeking mental health services in distressed older adults.

Older adults are especially unlikely to seek mental health services, and internalized stigma is a key reason why. However, little research has investigated which older adults are particularly likely to have stigma influence help-seeking. To address this, we tested whether perceived control (PC) moderates an internalized stigma model in which public stigma is internalized as self-stigma, which negatively predicts help-seeking attitudes and help-seeking intentions. We employed moderated mediation analysis of cross-sectional, secondary data from 348 psychologically distressed Canadian adults aged 65 years and older. Participants completed an online survey that included measures of public stigma of help-seeking, self-stigma of help-seeking, help-seeking attitudes, conditional help-seeking intentions, psychological distress, and PC. PC emerged as a moderator of the internalized stigma model. Those lower in PC were more likely to have public stigma negatively predict help-seeking intentions through the serial mediation of (a) self-stigma and (b) help-seeking attitudes. Further, those lower in PC were more likely to have public stigma internalized as self-stigma and more likely to have negative help-seeking attitudes predict lower help-seeking intentions. Finally, those lower in PC also had lower help-seeking intentions in the face of low levels of self-stigma. These results contribute to a nuanced understanding of which older adults are unlikely to seek help. Identifying PC as a moderator of the internalized stigma model suggests that interventions that enhance PC should protect against public stigma's internalization and improve help-seeking behaviors for older adults who need such help.

Increased frequency of light physical activity during midlife and old age buffers against cognitive declines.

Although it is well established that moderate-to-vigorous physical activity (MVPA) buffers against declines in cognitive health, less is known about the benefits of light physical activity (LPA). Research on the role of LPA is crucial to advancing behavioral interventions to improve late life health outcomes, including cognitive functioning, because this form of physical activity remains more feasible and amenable to change in old age. Our study examined the extent to which increases in LPA frequency protected against longitudinal declines in cognitive functioning and whether such a relationship becomes pronounced in old age when opportunities for MVPA are typically reduced. We analyzed 9-year data from the national Midlife in the United States Study (n = 2,229; Mage = 56 years, range = 33-83; 56% female) using autoregressive models that assessed whether change in LPA frequency predicted corresponding changes in episodic memory and executive functioning in middle and later adulthood. Increases in LPA frequency predicted less decline in episodic memory (ß = 0.06, p = .004) and executive functioning (ß = 0.14, p < .001) over the 9-year follow-up period, even when controlling for moderate and vigorous physical activity. Effect sizes for moderate and vigorous physical activity were less than half that observed for LPA. Moderation models showed that, for episodic memory, the benefits of increases in LPA frequency were more pronounced at older ages. Findings suggest that increases in LPA over extended periods of time may help slow age-related cognitive declines, particularly in later life when opportunities for MVPA are often diminished.

Impact of extra-nodal extension and AJCC lymph node staging in predicting recurrence following lymphadenectomy in patients with melanoma.

BACKGROUND: Regional lymphadenectomy (RL) has traditionally been recommended in patients with melanoma found to have clinical lymphadenopathy or a positive sentinel lymph node biopsy (SLNB). Regional control of disease is still a relevant issue for patients, even after undergoing lymphadenectomy. The goal of this study was to identify the clinicopathologic characteristics that predict locoregional recurrence in patients who have undergone either therapeutic lymph node dissection (TLND) or completion lymph node dissection (CLND) following SLNB. METHODS: Retrospective review of population-based cohort of patients with melanoma lymph node metastasis from the years 2005-2015. Multivariate, proportional hazards regression analysis was performed to determine factors predicting nodal recurrence. RESULTS: 586 patients underwent a RL, with a median follow up of 35 months. Overall, in-basin recurrence rates in the axilla, groin, and head/neck were 7.7 â€‹%, 8.7 â€‹% and 9.2 â€‹%, respectively. Higher unadjusted recurrence rates occurred following CLND than TLND of the groin (12.8 â€‹% vs 4.5 â€‹%) and neck (10.0 â€‹% vs 4.7 â€‹%) but not the axilla (7.5 â€‹% vs 8.0 â€‹%). Upon multivariate analysis, ENE (HR 2.77; p=<0.0001) and the AJCC lymph node stage (N3 vs N1) (HR 2.51; p â€‹= â€‹0.025) were predictive of regional recurrence. CONCLUSION: The AJCC nodal stage and the presence of extranodal extension were the only variables impacting regional recurrence following regional lymphadenectomy for melanoma. When considering regional disease control, they should be factored into treatment decisions, and surveillance strategies.

Using Electronic Handgrip Dynamometry and Accelerometry to Examine Multiple Aspects of Handgrip Function in Master Endurance Athletes: A Pilot Study.

ABSTRACT: Klawitter, LA, Hackney, KJ, Christensen, BK, Hamm, JM, Hanson, M, and McGrath, R. Using electronic handgrip dynamometry and accelerometry to examine multiple aspects of handgrip function in master endurance athletes: A Pilot Study. J Strength Cond Res 37(9): 1777-1782, 2023-Electronic handgrip dynamometry and accelerometry may provide novel opportunities to comprehensively measure muscle function for human performance, especially for master athletes. This investigation sought to determine the multivariate relationships between maximal strength, asymmetry, rate of force development, fatigability, submaximal force control, bimanual coordination, and neuromuscular steadiness to derive one or more handgrip principal components in master-aged endurance athletes. We included n = 31 cyclists and triathletes aged 35-70 years. Maximal strength, asymmetry, rate of force development, fatigability, submaximal force control, bimanual coordination, and neuromuscular steadiness were measured twice on each hand using electronic handgrip dynamometry and accelerometry. The highest performing measures were included in the analyses. A principal component analysis was conducted to derive a new collection of uncorrelated variables from the collected handgrip measurements. Principal components with eigenvalues >1.0 were kept, and individual measures with a factor loading of |>0.40| were retained in each principal component. There were 3 principal components retained with eigenvalues of 2.46, 1.31, and 1.17. The first principal component, "robust strength," contained maximal strength, rate of force development, submaximal force control, and neuromuscular steadiness. The second principal component, "bilateral synergy," contained asymmetry and bimanual coordination, whereas the third principal component, "muscle conditioning," contained fatigability. Principal components 1, 2, and 3 explained 44.0, 31.6, and 24.4% of the variance, respectively. Different dimensions of muscle function emerged from our findings, suggesting the potential of a muscle function battery. Further research examining how these measures are associated with appropriate human performance metrics and lower extremity correlates is warranted.

The Role of Different Weakness Cut-Points for Future Cognitive Impairment in Older Americans.

OBJECTIVES: New absolute and normalized handgrip strength (HGS) cut-points may not yield similar predictive value for cognitive performance. We sought to determine the associations of (1) each absolute and normalized weakness cut-point, and (2) compounding weakness on future cognitive impairment in older Americans. DESIGN: Longitudinal panel. SETTING AND PARTICIPANTS: The analytic sample included 11,116 participants aged ≥65 years from the 2006 to 2018 waves of the Health and Retirement Study. Participants from the Health and Retirement Study completed detailed interviews that included physical measures and core interviews. METHODS: The modified Telephone Interview of Cognitive Status assessed cognitive function and persons scoring <11 were classified as having a cognitive impairment. A handgrip dynamometer measured HGS. Men were considered weak if their HGS was <35.5 kg (absolute), <0.45 kg/kg (body mass normalized), or <1.05 kg (body mass index normalized), whereas women were classified as weak if their HGS was <20.0 kg, <0.337 kg/kg, or <0.79 kg. Compounding weakness included those below 1, 2, or all 3 cut-points. Generalized estimating equations quantified the associations. RESULTS: Persons considered weak under the absolute cut-point had 1.62 (95% CI 1.34-1.96) greater odds for future cognitive impairment, but no significant associations were observed for those classified as weak under the body mass [odds ratio (OR) 1.12, CI 0.91-1.36] and body mass index normalized (OR 1.17, CI 0.95-1.43) cut-points. Older Americans below all 3 weakness cut-points had 1.47 (CI 1.15-1.88) greater odds for future cognitive impairment, but no significant associations were found for persons classified as weak under 1 (OR 1.08, CI 0.83-1.42) or 2 (OR 1.19, CI 0.91-1.55) cut-points. CONCLUSIONS AND IMPLICATIONS: Our findings suggest that each weakness cut-point has differential prognostic value for future cognitive impairment, and aggregating weakness cut-points may improve their predictive utility. Consideration should be given to how weakness categories are uniquely linked to cognitive function.

Breast-Conserving Therapy is Associated with Improved Survival Without an Increased Risk of Locoregional Recurrence Compared with Mastectomy in Both Clinically Node-Positive and Node-Negative Breast Cancer Patients.

INTRODUCTION: Randomized trials demonstrated equivalent survival between breast-conserving surgery combined with radiotherapy (BCT) and mastectomy alone. Contemporary retrospective studies using pathological stage have reported improved survival with BCT. However, pathological information is unknown before surgery. To mimic real-world surgical decision-making, this study assesses oncological outcomes by using clinical nodal status. METHODS: Female patients aged 18-69 years who were treated with upfront BCT or mastectomy between 2006 and 2016 for T1-3N0-3 breast cancer were identified by using prospective, provincial database. The patients were divided into clinically node-positive (cN+) and node-negative (cN0) strata. Multivariable logistic regression was used to assess the effect of local treatment type on overall survival (OS), breast cancer-specific survival (BCSS), and locoregional recurrence (LRR). RESULTS: Of 13,914 patients, 8228 had BCT and 5686 had mastectomy. Mastectomy patients had higher-risk clinicopathological factors: pathologically positive axillary staging was 21% in BCT and 38% in mastectomy groups. Most patients received adjuvant systemic therapy. For cN0 patients, 7743 had BCT and 4794 had mastectomy. On multivariable analysis, BCT was associated with improved OS (hazard ratio [HR] 1.37, p < 0.001) and BCSS (HR 1.32, p < 0.001), whereas LRR was not different between the groups (HR 0.84, p = 0.1). For cN+ patients, 485 had BCT and 892 had mastectomy. On multivariable analysis, BCT was associated with improved OS (HR 1.46, p = 0.002) and BCSS (HR 1.44, p = 0.008), whereas LRR was not different between the groups (HR 0.89, p = 0.7). CONCLUSIONS: In the era of contemporary systemic therapy, BCT was associated with better survival than mastectomy, without an increased risk of locoregional recurrence for both cN0 and cN+ presentations.

The Prevalence and Trends of Instrumental Activities of Daily Living Impairments in the United States from 2008-2018.

Background: Instrumental activities of daily living (IADL) are neuropsychological-driven tasks that are linked to cognitive dysfunction. Examining population-based IADL deficits may reveal insights for the presence of these impairments in the United States. Objective: This investigation sought to evaluate the prevalence and trends of IADL impairments in Americans. Methods: A secondary analysis of data from the 2006-2018 waves of the Health and Retirement Study was conducted. The overall unweighted analytic sample included 29,764 Americans aged≥50 years. Respondents indicated their ability to perform six IADLs: manage money, manage medications, use a telephone, prepare hot meals, shop for groceries, and use a map. Persons reporting difficulty or an inability to complete an individual IADL were considered as having a task-specific impairment. Similarly, those indicating difficulty or an inability to perform any IADL were classified as having an IADL impairment. Sample weights were utilized to generate nationally-representative estimates. Results: Having an impairment in using a map (2018 wave: 15.7% (95% confidence interval (CI): 15.0-16.4) had the highest prevalence in individual IADLs regardless of wave examined. The overall prevalence of IADL impairments declined during the study period (p < 0.001) to 25.4% (CI: 24.5-26.2) in the 2018 wave. Older Americans and women had a consistently higher prevalence of IADL impairments compared to middle-aged Americans and men, respectively. The prevalence of IADL impairments was also highest among Hispanics and non-Hispanic Blacks. Conclusion: IADL impairments have declined over time. Continued surveillance of IADLs may help inform cognitive screening, identify subpopulations at risk of impairment, and guide relevant policy.

Downward adjustment of rehabilitation goals may facilitate post-stroke arm motor recovery.

Objective: Patients starting with physical rehabilitation often hold unrealistically high expectations for their recovery. Because of a lower-than-expected rate of recovery, such unrealistic goals have been linked to adverse effects on mental health. Additionally, overtraining due to overly ambitious goals can lead to suboptimal recovery. We investigated the effectiveness of adjusting rehabilitation goals to a more realistic level as a strategy to select appropriate exercise intensity and achieve better recovery outcomes. Design: Patients with arm paralysis from recent stroke were recruited and went through 6-8 weeks of telerehabilitation and in-clinic rehabilitation programme conducted at 11 US sites (N = 124). Main Outcome Measures: Adjustment of recovery goal was assessed in two timepoints during the rehabilitation programme and arm motor function was assessed before and after the clinical trial. Results: Greater use of goal adjustment strategies predicted better recovery of arm motor function, independent from therapy compliance. This pattern was observed only when the choice of exercises is patient-regulated rather than directed by a physical therapist. Conclusion: Benefits from goal adjustment were more pronounced among patients who entered the programme with poorer motor functions, suggesting that goal adjustment is the most beneficial when goals of complete recovery are most unrealistic.

An Updated Analysis of the Survival Endpoints of ASCENDE-RT.

PURPOSE: Using the primary endpoint of time to biochemical progression (TTP), Androgen Suppression Combined with Elective Nodal and Dose Escalated Radiation Therapy (ASCENDE-RT) randomized National Comprehensive Cancer Network patients with intermediate and high-risk prostate cancer to low-dose-rate brachytherapy boost (LDR-PB) or dose-escalated external beam boost (DE-EBRT). Randomization to the LDR-PB arm resulted in a 2-fold reduction in biochemical progression compared with the DE-EBRT group at a median follow-up of 6.5 years (P < .001). Herein, the primary endpoint and secondary survival endpoints of the ASCENDE-RT trial are updated at a 10-year median follow-up. METHODS: Patients were randomly assigned to either the LDR-PB or the DE-EBRT arm (1:1). All patients received 1 year of androgen deprivation therapy and 46 Gy in 23 fractions of pelvic RT. Patients in the DE-EBRT arm received an additional 32 Gy in 16 fractions, and those in the LDR-PB arm received an 125I implant prescribed to a minimum peripheral dose of 115 Gy. Two hundred patients were randomized to the DE-EBRT arm and 198 to the LDR-PB arm. RESULTS: The 10-year Kaplan-Meier TTP estimate was 85% ± 5% for LDR-PB compared with 67% ± 7% for DE-EBRT (log rank P < .001). Ten-year time to distant metastasis (DM) was 88% ± 5% for the LDR-PB arm and 86% ± 6% for the DE-EBRT arm (P = .56). There were 117 (29%) deaths. Ten-year overall survival (OS) estimates were 80% ± 6% for the LDR-PB arm and 75% ± 7% for the DE-EBRT arm (P = .51). There were 30 (8%) patients who died of prostate cancer: 12 (6%) in the LDR-PB arm, including 2 treatment-related deaths, and 18 (9%) in the DE-EBRT arm. CONCLUSIONS: Men randomized to the LDR-PB boost arm of the ASCENDE-RT trial continue to experience a large advantage in TTP compared with those randomized to the DE-EBRT arm. ASCENDE-RT was not powered to detect differences in its secondary survival endpoints (OS, DM, and time to prostate cancer-specific death) and none are apparent.

Attributional retraining: Promoting psychological wellbeing in older adults with compromised health.

Older adults make up the largest portion of the population of physically inactive individuals. Health challenges, and psychological barriers (e.g., maladaptive causal attributions), contribute to reduced activity engagement and low perceived control. This pilot study tested an attributional retraining (AR) intervention designed to increase control-related outcomes in a physical activity context for older adults with compromised health. Using a randomized treatment design, we examined treatment effects on a sample of older adults attending a day hospital (N = 37, M age = 80). We employed ANCOVAs, controlling for age, sex, and morbidity, to assess differences in post-treatment outcomes between AR and No-AR conditions. AR recipients (vs. No-AR) reported lower post-treatment helplessness and more perceived control over their health. Our study offers evidence for AR to increase control-related outcomes and lays the groundwork for further research into supporting older adult populations with compromised health.

Undiagnosed Dementia Is Associated with Poor Physical Function in Older Adults.

BACKGROUND: Older adults with a cognitive impairment, including those not yet diagnosed, may have deficits in their physical function. OBJECTIVE: We sought to determine the associations of cognitive impairment consistent with dementia (CICD) diagnosis status on handgrip strength, gait speed, and functional disability in older adults. METHODS: The analytical sample included 8,383 adults aged ≥65-years without history of stroke, cancers, neurological conditions, or brain damage who participated in at least one-wave of the 2010-2016 waves of the Health and Retirement Study. A handgrip dynamometer measured handgrip strength. Men with handgrip strength <26 kg and women <16 kg were weak. Gait speed was timed across a 2.5-m course and those with slowness had gait speed <0.8 m/s. Participants with difficulty or an inability in completing any basic activities of daily living had a functional disability. The adapted Telephone Interview of Cognitive Status evaluated cognitive function. Persons with scores <7 had a CICD. Healthcare provider dementia-related diagnosis was self-reported. Undiagnosed CICD was defined as no reported dementia-related diagnosis but had CICD, while diagnosed CICD was classified as reporting a dementia-related diagnosis. Covariate-adjusted logistic models were used for the analyses. RESULTS: Persons with undiagnosed CICD had 1.37 (95% confidence interval (CI): 1.04-1.80) greater odds for weakness and 2.02 (CI: 1.39-2.94) greater odds for slow gait speed. Older adults with diagnosed CICD had 2.29 (CI: 1.32-3.97) greater odds for slowness and 1.85 (CI: 1.19-2.90) greater odds for functional disability. CONCLUSION: Screening for CICD could be recommended when defects in physical function are observed in older adults.

Survival Outcomes in Metastatic Ewing Sarcoma Treated With Whole-Lung Radiation.

Background and objective There is a scarcity of research on outcomes in patients with metastatic Ewing sarcoma limited to pulmonary metastases who receive whole-lung radiotherapy (WLRT). In light of this, this study aimed to evaluate the use of WLRT and compare the survival outcomes between patients with metastatic Ewing sarcoma who received treatment with WLRT and those who did not. Materials and methods Patients of all ages with metastatic Ewing sarcoma restricted to the lung who were referred to the British Columbia (BC) Cancer from 1995 to 2017 were identified from the Sarcoma Outcomes Unit (SARCOU). Patient demographics and tumor and treatment characteristics were compared between cohorts treated with WLRT versus those who did not undergo WLRT. Five-year progression-free survival (PFS) and overall survival (OS) were evaluated using Kaplan-Meier (KM) estimates and compared between treatment groups with log-rank tests. Results The study cohort comprised 30 patients (median follow-up time: 6.8 years). Overall, the median age of the patients was 16 years (range: 4-86 years) and 60% were female; the primary disease sites were as follows: 27% axial skeleton, 53% appendicular skeleton, 20% visceral, 86% had ≥2 lung metastases, and 60% had bilateral disease. Fifteen (50%) patients received WLRT (median of 1500 cGy in 10 fractions). Chemotherapy was used in 97% of patients. The rate of surgery for lung metastases was 40%, which was similar between the WLRT and non-WLRT groups. The median size of the largest lung metastasis in the WLRT cohort was 1 cm (range: 0.3-1.8 cm), compared to 2 cm (range 0.5-6.7 cm) in the non-WLRT cohort (p=0.05). Demographics and tumor characteristics were otherwise not significantly different between the two treatment groups (all p>0.05). Among patients who received WLRT, 53% had complete response (CR), 7% partial response (PR), and 40% had disease progression. The five-year PFS was 86% vs. 59% (p=0.33) and OS was 78% vs. 54% (p=0.24) respectively for patients in the WLRT group vs. those in the non-WLRT group. The five-year PFS outcomes were higher on univariate analysis in patients with appendicular skeletal compared to axial skeletal and visceral primary sites (87.5% vs. 58% vs. 50%, respectively, p=0.02) and in patients with the size of the largest lung metastasis <2 cm vs. those with a size ≥2 cm (80% vs. 25%, p=0.04). Conclusions Patients treated with WLRT had a smaller-volume lung disease and over half of the patients who received WLRT had either complete or partial response. Trends of improved PFS and OS at five years were observed among patients who received WLRT compared to the non-WLRT group, but these were not statistically significant.

Adjustment and acceptance beliefs in achievement settings: Implications for student wellbeing.

Research suggests that when dealing with personal setbacks, secondary control (SC) adjustment and acceptance beliefs can foster psychological wellbeing. However, little research has examined these beliefs, in combination, and how they impact students in their academic development. We conducted secondary analysis using an eight-month longitudinal study design over a two-semester introductory course on a sample of university students (n = 237; 64% female; M age = 19 years old). Multiple regression analyses assessed whether the students' Semester 1 adjustment and acceptance SC beliefs influenced Semester 2 learning-related emotions, perceived stress, and perceived course success, and whether Adjustment x Acceptance interactions emerged involving these outcomes. Adjustment beliefs promoted learning-related positive emotions (hope, pride), perceived course success, and reduced perceived stress; acceptance predicted higher shame and perceived stress. Students' adjustment predicted lower helplessness for students with high acceptance beliefs. These findings are discussed in light of the role that SC beliefs might play in curbing psychological distress reported by students on postsecondary campuses.

Goal adjustment capacities in uncontrollable life circumstances: Benefits for psychological well-being during COVID-19.

Goal adjustment capacities (i.e., goal disengagement and goal reengagement) are core self-regulatory resources theorized to buffer psychological well-being during intractable life circumstances. However, research has yet to examine whether these capacities protect well-being for individuals who encounter uncontrollable losses in their ability to pursue important life goals due to the COVID-19 pandemic. Using a nationally-representative sample of U.S. adults aged 18-80 (n = 292), the present longitudinal study examined the extent to which goal disengagement and reengagement predicted levels and change in psychological well-being for individuals who differed in perceived control over their goals early in the pandemic. Results from multilevel growth models showed that goal reengagement, but not goal disengagement, capacities predicted higher levels of well-being during the pandemic (lower perceived stress, depressive symptoms; higher life satisfaction, meaning in life). Moderation models showed the benefits of goal reengagement for well-being were pronounced among individuals who perceived pandemic-induced declines in control over their goals. Findings inform theories of motivation and self-regulation and point to the adaptive value of goal reengagement capacities during uncontrollable life circumstances.

Using a Weekly Patient-Reported Outcome Questionnaire to Track Acute Toxicity in Patients Undergoing Pelvic Radiotherapy for Gynecologic Cancers.

There are limited patient-reported outcome (PRO) data tracking changes in toxicity in patients actively undergoing radiotherapy. Between 2015−2019, acute toxicity was prospectively measured in 698 patients undergoing a 5-week course of pelvic radiotherapy for gynecologic cancers using a weekly PRO questionnaire. Our questionnaire was able detect a pattern of onset and resolution of acute gastrointestinal (GI) and genitourinary (GU) toxicity in 27 out of 32 questions. Logistic regression analysis showed that increasing GI and GU toxicity at week 2 could predict for severe toxicity at week 5. However, due to a low number of severe events, univariate results could not be productively added to a multivariate model. We observed a >70% response rate for all sections of the questionnaire, except for questions on sexual and vaginal health, which had a 13% average response rate. By demonstrating that PRO data can be used to track acute toxicity during radiotherapy, there is a need to further examine how this tool may be implemented in the clinic to provide complex, adaptive care, such as early side effect management, and modifying radiation delivery in real-time.

Discrete negative emotions and goal disengagement in older adulthood: Context effects and associations with emotional well-being.

This study examined whether sadness, but not anger, could facilitate adaptive goal disengagement capacity in the context of older adult's stress-related experiences. To this end, we investigated whether the within-person effects of sadness and anger on older adults' goal disengagement capacity were moderated by stress perceptions and diurnal cortisol levels. In addition, we tested whether an association between sadness and goal disengagement capacity could protect emotional well-being when older adults experience higher than normal perceived stress or cortisol. The study used data from a 6-wave 10-year longitudinal study of 184 community-dwelling older adults (Mage = 72.08, SDage = 5.70). Participants' sadness, anger, goal disengagement capacity, perceived stress, diurnal cortisol levels, emotional well-being (i.e., positive and negative affect), and sociodemographic variables were assessed at each wave. Hierarchical linear modeling showed that within-person increases in sadness, but not anger, predicted increased goal disengagement capacity among older adults who generally secreted high levels of cortisol. Moreover, older adults' who disengaged more easily when they felt sad were protected from declines in positive affect during assessments in which they secreted high, but not low, levels of cortisol. The study's findings suggest that generally enhanced cortisol output may facilitate an association between sadness and older adults' goal disengagement capacity and that this process may protect against declines in emotional well-being.

The Prognostic Impact of Radiotherapy Delays in Oropharynx Carcinoma and the Role of p16 Status.

OBJECTIVE: A retrospective analysis was performed to evaluate the prognostic significance of treatment delays (TDs) for oropharynx carcinoma patients treated with definitive radiotherapy (RT), comparing p16+ versus p16- disease. MATERIALS AND METHODS: Patients treated between 2012 and 2016 were analyzed (n=763). TD was defined as the time from pathologic diagnosis to initiation of RT. TD thresholds of ≤60, 61 to 90, and >90 days were used to stratify outcomes. Time on treatment (TOT) delays were estimated based on the RT fractionation. TOT delay of 1 to 3 days was compared with >3 days. Predictors of cancer-specific survival (CSS) and locoregional recurrence (LRR) were evaluated on multivariable analysis. RESULTS: Six hundred fifty (85%) patients had p16+ disease. On multivariable analysis, TOT delay of 1 to 3 days versus <1 day was associated with inferior CSS (hazard ratio [HR]=1.81; 95% confidence interval [CI]: 1.02-3.22). TD >90 versus ≤60 days (HR=1.68; 95% CI: 0.98-3.04) and 61 to 90 versus ≤60 days (HR=0.94; 95% CI: 0.60-1.48) was not associated with CSS. TD >90 versus ≤60 days (HR=1.29; 95% CI: 0.66-2.52), TD 61 to 90 versus ≤60 days (HR=0.98; 95% CI: 0.64-1.52), TOT 1 to 3 versus <1 day (HR=0.91; 95% CI: 0.39-2.11), and TOT >3 versus <1 day (HR=1.79; 95% CI: 0.80-3.99) were not associated with LRR. There was no interaction between p16 status and TD in relation to LRR (P=0.27) or CSS (P=0.17). CONCLUSIONS: TDs were not significantly associated with CSS or LRR. TOT of 1 to 3 days was associated with inferior CSS. p16 status should not be a significant factor when triaging RT start dates.
