Psychosocial consequences of head and neck cancer symptom burden after chemoradiation: a mixed-method study

PURPOSE

Patients with head and neck cancer (HNC) experience significant symptom burden from combination chemotherapy and radiation (chemoradiation) that affects acute and long-term health-related quality of life (HRQOL). However, psychosocial impacts of HNC symptom burden are not well understood. This study examined psychosocial consequences of treatment-related symptom burden from the perspectives of survivors of HNC and HNC healthcare providers.

METHODS

This was a cross-sectional, mixed-method study conducted at an NCI-designated comprehensive cancer center. Participants (N = 33) were survivors of HNC who completed a full course of chemoradiation (n = 20) and HNC healthcare providers (n = 13). Participants completed electronic surveys and semi-structured interviews.

RESULTS

Survivors were M = 61 years old (SD = 9) and predominantly male (75%), White (90%), non-Hispanic (100%), and diagnosed with oropharynx cancer (70%). Providers were mostly female (62%), White (46%) or Asian (31%), and non-Hispanic (85%) and included physicians, registered nurses, an advanced practice nurse practitioner, a registered dietician, and a speech-language pathologist. Three qualitative themes emerged: (1) shock, shame, and self-consciousness, (2) diminished relationship satisfaction, and (3) lack of confidence at work. A subset of survivors (20%) reported clinically low social wellbeing, and more than one-third of survivors (35%) reported clinically significant fatigue, depression, anxiety, and cognitive dysfunction.

CONCLUSION

Survivors of HNC and HNC providers described how treatment-related symptom burden impacts psychosocial identity processes related to body image, patient-caregiver relationships, and professional work. Results can inform the development of supportive interventions to assist survivors and caregivers with navigating the psychosocial challenges of HNC treatment and survivorship.

"I couldn't connect the wires in my brain." Young adult cancer survivors' experience with cognitive functioning

OBJECTIVE

There is a dearth of literature describing young adult (YA) cancer survivors' experiences with cancer-related cognitive impairment (CRCI). We aimed to elucidate CRCI among YA cancer survivors and identify potentially modifiable risk factors.

METHODS

We conducted individual qualitative interviews with YA cancer survivors aged 18-30 years at study enrollment and used applied thematic analysis to identify themes across three topics (i.e., affected cognitive abilities, risk and protective factors influencing the impact of CRCI, and strategies for coping with CRCI).

RESULTS

YA cancer survivors (N = 20) were, on average, 23 years old at diagnosis and 26 years old when interviewed. Diverse cancer types and treatments were represented; most participants (85%) had completed cancer treatment. Participants described experiences across three qualitative topics: (1) affected cognitive abilities (i.e., concentration and attention, prospective memory, and long-term memory), (2) Risk factors (i.e., fatigue, sleep problems, mood, stress/distractions, and social isolation) and protective factors (i.e., social support), and (3) coping strategies, including practical strategies that helped build self-efficacy (e.g., writing things down, reducing distractions), beneficial emotion-focused coping strategies (e.g., focus on health, faith/religion), strategies with mixed effects (i.e., apps/games, medications/supplements, and yoga), and "powering through" strategies that exacerbated stress.

CONCLUSIONS

YA cancer survivors experience enduring cognitive difficulties after treatment. Specific concerns highlight the importance of attention and executive functioning impairments, long-term memory recall, and sensitivity to distractions. Future work is needed to improve assessment and treatment of CRCI among YA cancer survivors.

Feasibility and acceptability of C-PRIME: A health promotion intervention for family caregivers of patients with colorectal cancer

PURPOSE

This study aimed to test the feasibility and acceptability of a digital health promotion intervention for family caregivers of patients with advanced colorectal cancer and explore the intervention's preliminary efficacy for mitigating the impact of caregiving on health and well-being.

METHODS

We conducted a single-arm pilot feasibility trial of C-PRIME (Caregiver Protocol for Remotely Improving, Monitoring, and Extending Quality of Life), an 8-week digital health-promotion behavioral intervention involving monitoring and visualizing health-promoting behaviors (e.g., objective sleep and physical activity data) and health coaching (NCT05379933). A priori benchmarks were established for feasibility (≥ 50% recruitment and objective data collection; ≥ 75% session engagement, measure completion, and retention) and patient satisfaction (> 3 on a 1-5 scale). Preliminary efficacy was explored with pre- to post-intervention changes in quality of life (QOL), sleep quality, social engagement, and self-efficacy.

RESULTS

Participants (N = 13) were M = 52 years old (SD = 14). Rates of recruitment (72%), session attendance (87%), assessment completion (87%), objective data collection (80%), and retention (100%) all indicated feasibility. All participants rated the intervention as acceptable (M = 4.7; SD = 0.8). Most participants showed improvement or maintenance of QOL (15% and 62%), sleep quality (23% and 62%), social engagement (23% and 69%), and general self-efficacy (23% and 62%).

CONCLUSION

The C-PRIME digital health promotion intervention demonstrated feasibility and acceptability among family caregivers of patients with advanced colorectal cancer. A fully powered randomized controlled trial is needed to test C-PRIME efficacy, mechanisms, and implementation outcomes, barriers, and facilitators in a divserse sample of family caregivers.

TRIAL REGISTRATION

The Caregiver Protocol for Remotely Improving, Monitoring, and Extending Quality of Life (C-PRIME) study was registered on clinicaltrials.gov, NCT05379933, in May 2022.

Acute cancer-related symptoms and concerns among patients receiving chemotherapy: current state of the science

PURPOSE

This study provides an updated evaluation of the prevalence and severity of acute cancer-related symptoms and quality of life (QOL) concerns among patients treated with emetogenic chemotherapy.

METHODS

Patients were recruited to a larger, multi-site observational study prior to starting chemotherapy. Participants completed sociodemographic questionnaires and clinical data were abstracted via medical record review. Symptoms and QOL were assessed 5 days after starting moderately or highly emetogenic chemotherapy. Functional Assessment of Cancer Therapy - General assessed QOL concerns. Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events evaluated symptoms. Symptoms were considered severe when participants responded "severe" or "very severe."

RESULTS

Participants (N = 1174) were on average 58 ± 13 years, mostly female (73%), non-Hispanic (89%), and White (87%). Most participants were diagnosed with breast (38.1%), gynecological (20%), and gastrointestinal (17.1%) cancer. The most common QOL concerns of any severity were fatigue (94%), anhedonia (89%), dissatisfaction with QOL (86%), and sleep disturbance (86%). The most common severe QOL concerns were anhedonia (44%), fatigue (40%), and inability to work (38%). Decreased appetite (74%), pain (71%), and constipation (70%) were the most common symptoms of any severity, as well as most common severe symptoms (13%, 18%, and 18%, respectively).

CONCLUSION

Herein, updates are provided in regard to QOL concerns and symptoms reported by patients in the days after chemotherapy and demonstrates that concerns and symptoms have shifted in the last decade.

Patient-Reported Outcomes among Multiple Myeloma Patients Treated with Standard of Care Idecabtagene Vicleucel

Idecabtagene vicleucel (ide-cel) was the first FDA-approved chimeric antigen receptor T-cell therapy for relapsed/refractory multiple myeloma (RRMM) patients. This was the first study to evaluate patient-reported outcomes (PROs) among RRMM patients receiving ide-cel in standard of care (SOC). We prospectively assessed health-related quality of life (HRQOL) and symptoms from pre-infusion (baseline) through day (D)90 post-infusion. Baseline PRO associations with patient characteristics, mean PRO changes, and time to stable change were evaluated with t-tests, linear mixed-effects models, and Kaplan-Meier analyses, respectively. Within-person change scores and minimally important difference thresholds determined clinical and meaningful significance. Participants (n = 42) were a median of 66 years old (range: 43-81). At baseline, extramedullary disease was associated with worse physical well-being (p = 0.008), global pain (p < 0.001), performance status (p = 0.002), and overall symptom burden (p < 0.001). Fatigue (p < 0.001) and functional well-being (p = 0.003) worsened by D7 before returning to baseline levels. Overall HRQOL (p = 0.008) and physical well-being (p < 0.001) improved by D60. Most participants reported PRO improvement (10-57%) or maintenance (23-69%) by D90. The median time it took to stabile deterioration in functional well-being was 14 days. The median time it took to stabile improvement in physical and emotional well-being was 60 days. Overall, RRMM patients reported improvements or maintenance of HRQOL and symptom burden after SOC ide-cel.

Relationships among Inflammatory Biomarkers and Objectively Assessed Physical Activity and Sleep during and after Chemotherapy for Gynecologic Malignancies

Little is known regarding associations between inflammatory biomarkers and objectively measured physical activity and sleep during and after chemotherapy for gynecologic cancer; thus, we conducted a longitudinal study to address this gap. Women with gynecologic cancer (patients) and non-cancer controls (controls) completed assessments before chemotherapy cycles 1, 3, and 6 (controls assessed contemporaneously), as well as at 6- and 12-month follow-ups. Physical activity and sleep were measured using wrist-worn actigraphs and sleep diaries, and blood was drawn to quantify circulating levels of inflammatory markers. Linear and quadratic random-effects mixed models and random-effects fluctuation mixed models were used to examine physical activity and sleep over time, as well as the associations with inflammatory biomarkers. On average, patients (n = 97) and controls (n = 104) were 62 and 58 years old, respectively. Compared to controls, patients were less active, more sedentary, had more time awake after sleep onset, and had lower sleep efficiency (p-values < 0.05). Across groups, higher levels of TNF-α were associated with more sedentary time and less efficient sleep (p-values ≤ 0.05). Higher levels of IL-1β, TNF-α, and IL-6 were associated with lower levels of light physical activity (p-values < 0.05). Associations between inflammatory biomarkers, physical activity, and sleep did not differ between patients and controls. Given these results, we speculate that inflammation may contribute to less physical activity and more sleep problems that persist even 12 months after completing chemotherapy.

Relationships among Inflammatory Biomarkers and Self-Reported Treatment-Related Symptoms in Patients Treated with Chemotherapy for Gynecologic Cancer: A Controlled Comparison

Previous research suggests that inflammation triggers cancer-treatment-related symptoms (i.e., fatigue, depression, and disruptions in sleep and physical activity), but evidence is mixed. This study examined relationships between inflammatory biomarkers and symptoms in patients with gynecologic cancer compared to age-matched women with no cancer history (i.e., controls). Patients (n = 121) completed assessments before chemotherapy cycles 1, 3, and 6, and 6 and 12 months later. Controls (n = 105) completed assessments at similar timepoints. Changes in inflammation and symptomatology were evaluated using random-effects mixed models, and cross-sectional differences between patients and controls in inflammatory biomarkers and symptoms were evaluated using least squares means. Associations among inflammatory biomarkers and symptoms were evaluated using random-effects fluctuation mixed models. The results indicated that compared to controls, patients typically have higher inflammatory biomarkers (i.e., TNF-alpha, TNFR1, TNFR2, CRP, IL-1ra) and worse fatigue, depression, and sleep (ps < 0.05). Patients reported lower levels of baseline physical activity (p = 0.02) that became more similar to controls over time. Significant associations were observed between CRP, depression, and physical activity (ps < 0.05), but not between inflammation and other symptoms. The results suggest that inflammation may not play a significant role in fatigue or sleep disturbance among gynecologic cancer patients but may contribute to depression and physical inactivity.

Patient-reported outcomes in immunotherapy for head and neck cancer

BACKGROUND

Data about patient-reported outcomes (PROs) among patients with head and neck squamous cell carcinoma (HNSCC) treated with immune checkpoint inhibitors are sparse. Our exploratory study evaluated PROs in patients with HNSCC starting treatment with immune checkpoint inhibitor monotherapy or combination therapy with cetuximab.

METHODS

Patients were recruited prior to receipt of their first checkpoint inhibitor therapy infusion. Participants completed measures of checkpoint inhibitor toxicities and quality of life (QOL) at on-treatment clinic visits.

RESULTS

Among patients treated with checkpoint inhibitor monotherapy (n = 48) or combination therapy (n = 38) toxicity increased over time (p < 0.05), while overall QOL improved from baseline to 12 weeks, with stable or declining QOL thereafter (p < 0.05). There were no group differences in change in toxicity index or QOL. Toxicity index scores were significantly higher in the combination group at 18-20 weeks and 6 months post-initiation of immune checkpoint inhibitor (p < 0.05). There were no significant group differences at baseline, the 6-8 week (p = 0.13) or 3-month (p = 0.09) evaluations. The combination group reported better emotional well-being at baseline than the monotherapy group (p = 0.04), There were no other group differences QOL at baseline or later timepoints.

CONCLUSIONS

Despite increasing patient-reported toxicity, checkpoint inhibitor monotherapy and combination therapy were associated with similar transient improvements, then worsening, of QOL in patients with HNSCC.

Diet quality indices and changes in cognition during chemotherapy

PURPOSE

No evidence-based prevention strategies currently exist for cancer-related cognitive decline (CRCD). Although patients are often advised to engage in healthy lifestyle activities (e.g., nutritious diet), little is known about the impact of diet on preventing CRCD. This secondary analysis evaluated the association of pre-treatment diet quality indices on change in self-reported cognition during chemotherapy.

METHODS

Study participants (n = 96) completed the Block Brief Food Frequency Questionnaire (FFQ) before receiving their first infusion and the PROMIS cognitive function and cognitive abilities questionnaires before infusion and again 5 days later (i.e., when symptoms were expected to be their worst). Diet quality indices included the Dietary Approaches to Stop Hypertension (DASH), Alternate Mediterranean Diet (aMED), and a low carbohydrate diet index and their components. Descriptive statistics were generated for demographic and clinical variables and diet indices. Residualized change models were computed to examine whether diet was associated with change in cognitive function and cognitive abilities, controlling for age, sex, cancer type, treatment type, depression, and fatigue.

RESULTS

Study participants had a mean age of 59 ± 10.8 years and 69% were female. Although total diet index scores did not predict change in cognitive function or cognitive abilities, higher pre-treatment ratio of aMED monounsaturated/saturated fat was associated with less decline in cognitive function and cognitive abilities at 5-day post-infusion (P ≤ .001).

CONCLUSIONS

Higher pre-treatment ratio of monounsaturated/saturated fat intake was associated with less CRCD early in chemotherapy. Results suggest greater monounsaturated fat and less saturated fat intake could be protective against CRCD during chemotherapy.

Development and initial testing of TOGETHER-YA: an eHealth-delivered and group-based psychosocial intervention for young adult cancer survivors

PURPOSE

This study aimed to (1) develop TOGETHER-YA, an e-Health-delivered and group-based health-related quality of life (HRQOL) intervention for young adult (YA) cancer survivors aged 18-39 (Part 1), and (2) determine its initial feasibility and acceptability in a single-arm pilot trial (Part 2).

METHODS

TOGETHER-YA is a manualized, 10-week intervention for YA survivors that includes elements of relaxation training, cognitive-behavioral therapy, and health education. In Part 1, content was adapted from existing evidence-based interventions with feedback from YAs (N = 22) in four iterative focus groups. In Part 2, YA survivors (N = 11) participated in a single-arm pilot trial of TOGETHER-YA. Intervention groups were led by a trained facilitator over videoconference. Primary outcomes were feasibility (i.e., recruitment, session attendance, retention) and acceptability (i.e., participant satisfaction).

RESULTS

Focus groups reacted positively to TOGETHER-YA and provided actionable recommendations for enhancing its relevance and acceptability, which were implemented. In initial testing, all feasibility and acceptability benchmarks were met; 58% of eligible YAs were recruited, participants attended M = 6 intervention sessions (SD = 3), and 82% of participants were retained post-intervention. On average, participants "agreed" to "strongly agreed" with positive statements about the weekly sessions and the overall program.

CONCLUSION

TOGETHER-YA was developed in collaboration with YA cancer survivors and found to be feasible and acceptable in initial testing. TOGETHER-YA is the first HRQOL intervention for a broad range of YA survivors that is eHealth-delivered for convenience and group-based for peer support. Future large-scale trials should test its efficacy for improving HRQOL.

Spiritual well-being, distress and quality of life in Hispanic women diagnosed with cancer undergoing treatment with chemotherapy

OBJECTIVE

Previous studies have examined whether spiritual well-being is associated with cancer outcomes, but minority populations are under-represented. This study examines associations of baseline spiritual well-being and change in spiritual well-being with change in distress and quality of life, and explores potential factors associated with changes in spiritual well-being among Hispanic women undergoing chemotherapy.

METHODS

Participants completed measures examining spiritual well-being, distress, and quality of life prior to beginning chemotherapy and at weeks 7 and 13. Participants' acculturation and sociodemographic data were collected prior to treatment. Mixed models were used to examine the association of baseline spiritual well-being and change in spiritual well-being during treatment with change in distress and quality of life, and to explore whether sociodemographic factors, acculturation and clinical variables were associated with change in spiritual well-being.

RESULTS

A total of 242 participants provided data. Greater baseline spiritual well-being was associated with less concurrent distress and better quality of life (p < 0.001), as well as with greater emotional and functional well-being over time (p values < 0.01). Increases in spiritual well-being were associated with improved social well-being during treatment, whereas decreases in spiritual well-being were associated with worsened social well-being (p < 0.01). Married participants reported greater spiritual well-being at baseline relative to non-married participants (p < 0.001).

CONCLUSIONS

Greater spiritual well-being is associated with less concurrent distress and better quality of life, as well as with greater emotional, functional, and social well-being over time among Hispanic women undergoing chemotherapy. Future work could include developing culturally targeted spiritual interventions to improve survivors' well-being.

Longitudinal Collection of Patient-Reported Outcomes and Activity Data during CAR-T Therapy: Feasibility, Acceptability, and Data Visualization

Background: Clinicians must closely monitor patients for toxicities after chimeric antigen receptor T-cell therapy (CAR-T). Patient-reported outcomes (PROs) (e.g., toxicities, quality of life) and activity data (e.g., steps, sleep) may complement clinicians’ observations. This study tested the feasibility and acceptability of collecting PROs and activity data from patients with hematologic malignancies during CAR-T and explored preliminary data patterns. Methods: Participants wore a Fitbit tracker and completed PROs at several timepoints through 90-days post-infusion. Feasibility was assessed with a priori benchmarks for recruitment (≥50%), retention (≥70%), PRO completion (≥70%), and days wearing the Fitbit (≥50%). Acceptability was assessed with participant satisfaction (a priori benchmark > 2 on a 0−4 scale). Results: Participants (N = 12) were M = 66 years old (SD = 7). Rates of recruitment (68%), retention (83%), PRO completion (85%), and days wearing the Fitbit (85%) indicated feasibility. Satisfaction with completing the PROs (M = 3.2, SD = 0.5) and wearing the Fitbit (M = 2.9, SD = 0.5) indicated acceptability. Preliminary data patterns suggested that participants with better treatment response (vs. progressive disease) had a higher toxicity burden. Conclusions: Longitudinal PRO and activity data collection was feasible and acceptable. Data collected on a larger scale may be used to specify risk prediction models to identify predictors of severe CAR-T-related toxicities and inform early interventions.

Quality of life in caregivers of patients receiving chimeric antigen receptor T-cell therapy

OBJECTIVE

Informal family caregivers provide critical support for patients receiving chimeric antigen receptor (CAR) T-cell therapy. However, caregivers' experiences are largely unstudied. This study examined quality of life (QOL; physical functioning, pain, fatigue, anxiety, and depression), caregiving burden, and treatment-related distress in caregivers in the first 6 months after CAR T-cell therapy, when caregivers were expected to be most involved in providing care. Relationships between patients' clinical course and caregiver outcomes were also explored.

METHODS

Caregivers completed measures examining QOL and burden before patients' CAR T-cell therapy and at days 90 and 180. Treatment-related distress was assessed at days 90 and 180. Patients' clinical variables were extracted from medical charts. Change in outcomes was assessed using means and 99% confidence intervals. Association of change in outcomes with patient clinical variables was assessed with backward elimination analysis.

RESULTS

A total of 99 caregivers (mean age 59, 73% female) provided data. Regarding QOL, pain was significantly higher than population norms at baseline but improved by day 180 (p < .01). Conversely, anxiety worsened over time (p < .01). Caregiver burden and treatment-related distress did not change over time. Worsening caregiver depression by day 180 was associated with lower patient baseline performance status (p < .01). Worse caregiver treatment-related distress at day 180 was associated with lower performance status, intensive care unit admission, and lack of disease response at day 90 (ps < 0.01).

CONCLUSIONS

Some CAR T-cell therapy caregivers experience pain, anxiety, and burden, which may be associated patients' health status. Further research is warranted regarding the experience of CAR T-cell therapy caregivers.

Acute patient-reported outcomes in B-cell malignancies treated with axicabtagene ciloleucel

Chimeric antigen receptor T‐cell therapy with axicabtagene ciloleucel (axi‐cel) has considerably improved survival in adults with relapsed/refractory large B‐cell lymphoma. This study reports patient‐reported outcomes (PROs) such as quality of life (QOL) and toxicity in the first 90 days after treatment. Hematologic cancer patients treated with axi‐cel (N = 103, mean age = 61, 39% female) completed SF‐36 or PROMIS‐29 QOL questionnaires prior to treatment and 90 days after. PRO‐Common Terminology Criteria for Adverse Events toxicity items were completed by patients at baseline and 14, 30, 60, and 90 days after treatment. Mixed models examined change in PROs over time. From preinfusion to 90 days later, patients reported improvements in physical functioning, pain, and fatigue (ps < 0.01), but worsening of anxiety (p = 0.02). Patient‐reported toxicities worsened by day 14 with improvement thereafter. The five most severe symptoms at day 14 included fatigue, decreased appetite, dry mouth, diarrhea frequency, and problems with concentration. Results indicate improvement in some domains of QOL over time with transient patient‐reported toxicities.

Histone methyltransferase DOT1L coordinates AR and MYC stability in prostate cancer

The histone methyltransferase DOT1L methylates lysine 79 (K79) on histone H3 and is involved in Mixed Lineage Leukemia (MLL) fusion leukemogenesis; however, its role in prostate cancer (PCa) is undefined. Here we show that DOT1L is overexpressed in PCa and is associated with poor outcome. Genetic and chemical inhibition of DOT1L selectively impaired the viability of androgen receptor (AR)-positive PCa cells and organoids, including castration-resistant and enzalutamide-resistant cells. The sensitivity of AR-positive cells is due to a distal K79 methylation-marked enhancer in the MYC gene bound by AR and DOT1L not present in AR-negative cells. DOT1L inhibition leads to reduced MYC expression and upregulation of MYC-regulated E3 ubiquitin ligases HECTD4 and MYCBP2, which promote AR and MYC degradation. This leads to further repression of MYC in a negative feed forward manner. Thus DOT1L selectively regulates the tumorigenicity of AR-positive prostate cancer cells and is a promising therapeutic target for PCa.

Histone methyltransferase, DOTL1 is implicated in the pathogenesis of MLL-rearranged leukemia, however, not much is known of its role in prostate cancer (PCa). Here, the authors report that DOTL1 inhibition suppresses both androgen receptor and MYC pathways in a negative feed forward manner to reduce growth of AR-positive PCa.

Subjective cognition in chimeric antigen receptor T-cell therapy recipients

7020

Background: Chimeric antigen receptor T-cell (CAR-T) therapy can lead to durable responses in chemorefractory patients with hematologic malignancies. CAR-T, however, can be associated with neurotoxicity. There is a significant body of literature describing patient-reported concerns with cognition in hematopoietic cell transplant (HCT) recipients, a similar treatment group. However, little is known about subjective cognition in CAR-T patients. This study examined changes in subjective cognition over time in CAR-T recipients and compared their outcomes with allogeneic HCT recipients. Methods: At baseline and 90 days after infusion, participants completed the Everyday Cognition Questionnaire (ECog). The ECog provides scores for total cognition, memory, language, visuospatial abilities, planning, organization, divided attention, and satisfaction with cognition. Comparison data from allogeneic HCT recipients came from a previous observational study. Linear mixed models compared changes in subjective cognition between recipients of CAR-T and allogeneic HCT over time. Models were adjusted by age, marital status, education, and Karnofsky performance status. Results: Participants were 111 CAR-T recipients (mean age 60 years, 37% female) and 190 allogeneic HCT recipients (mean age 53, 42% female). Linear mixed models indicated CAR-T recipients’ subjective cognition didn’t change within the 90 days after infusion (p’s > .05). At baseline, there were no group differences between CAR-T and allogeneic HCT recipients in subjective cognition (p’s > 0.05). Over time, however, subjective cognition between groups differed. Specifically, CAR-T recipients reported stable subjective cognition whereas allogeneic HCT recipients reported worsening total subjective cognition (p = 0.04), memory (p = 0.02), visuospatial abilities (p = 0.01), planning (p = 0.01), and divided attention (p = 0.01). At follow-up, CAR-T recipients reported better total subjective cognition (p < 0.01), memory (p < 0.01), language (p = 0.01), visuospatial abilities (p < 0.01), planning (p < 0.01), and divided attention (p < 0.01) than allogeneic HCT recipients. Conclusions: Despite the neurotoxicity associated with CAR-T, patients can expect to perceive similar subjective cognition at day 90 compared to baseline. Future studies should also evaluate objective cognition in CAR-T recipients.

Efficacy of a Spanish-Language Self-Administered Stress Management Training intervention for Latinas undergoing chemotherapy

BACKGROUND

Cancer patients often report increased stress during chemotherapy. Stress management training has been shown to reduce this adverse outcome, but few interventions exist for Spanish-speaking Hispanic and Latina women (Latinas).

METHODS

Following community feedback (including focus groups/in-depth interviews), we transcreated the Spanish-Language Self-Administered Stress Management Training (SL-SAT) intervention based on our previously developed and implemented English-based intervention. Latinas about to begin chemotherapy were randomized to SL-SAT (n = 121) or usual care (n = 119). A Spanish-speaking interventionist met with SL-SAT participants who received the SL-SAT toolkit containing instructions in 3 well-established stress management techniques (deep breathing, progressive muscle relaxation and guided imagery, and use of coping self-statements). Usual care participants received an educational booklet about coping with chemotherapy. All patients were instructed by nurses on their chemotherapy medications and given a resource listing of local support groups. Outcomes were obtained at baseline, and 7 and 13 weeks after starting chemotherapy. Primary outcomes included anxiety and depression, cancer-related distress, emotional well-being, and spiritual well-being. Secondary outcomes included functional well-being, social/family well-being, physical well-being, symptom severity, and self-efficacy for managing stress. Data were analyzed by using mixed models.

RESULTS

In both groups, improvements were observed in emotional well-being (P = .01), and declines were observed in functional well-being (P = .05), and physical well-being (P < .0001). Symptom severity increased across the follow-up period (P < .001).

CONCLUSIONS

To be effective, stress management interventions for Latinas receiving chemotherapy may necessitate more attention from an interventionist, delivery of the intervention over a longer interval, and/or a group-based format.

Proteomic analyses of monocyte-derived macrophages infected with human immunodeficiency virus type 1 primary isolates from Hispanic women with and without cognitive impairment

The signature for human immunodeficiency virus type 1 (HIV-1) neurovirulence remains a subject of intense debate. Macrophage viral tropism is one prerequisite but others, including virus-induced alterations in innate and adaptive immunity, remain under investigation. HIV-1-infected mononuclear phagocytes (MPs; perivascular macrophages and microglia) secrete toxins that affect neurons. The authors hypothesize that neurovirulent HIV-1 variants affect the MP proteome by inducing a signature of neurotoxic proteins and thus affect cognitive function. To test this hypothesis, HIV-1 isolates obtained from peripheral blood of women with normal cognition (NC) were compared to isolates obtained from women with cognitive impairment (CI) and to the laboratory adapted SF162, a spinal fluid R5 isolate from a patient with HIV-1-associated dementia. HIV-1 isolates were used to infect monocyte-derived macrophages (MDMs) and infection monitored by secreted HIV-1 p24 by enzyme-linked immunosorbent assay (ELISA). Cell lysates of uninfected and HIV-1-infected MDMs at 14 days post infection were fractionated by cationic exchange chromatography and analyzed by surface enhanced laser desorption ionization time of flight (SELDI-TOF) using generalized estimating equations statistics. Proteins were separated by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (1D SDS-PAGE) and identified by tandem mass spectrometry. Levels of viral replication were similar amongst the HIV-1 isolates, although higher levels were obtained from one viral strain obtained from a patient with CI. Significant differences were found in protein profiles between virus-infected MDMs with NC, CI, and SF162 isolates (adjusted P value after multiple testing corrections, or q value <.10). The authors identified 6 unique proteins in NC, 7 in SF162, and 20 in CI. Three proteins were common to SF162 and CI strains. The MDM proteins linked to infection with CI strains were related to apoptosis, chemotaxis, inflammation, and redox metabolism. These findings support the hypothesis that the macrophage proteome differ when infected with viral isolates of women with and without CI.

Neuropsychological function in nondemented carriers of presenilin-1 mutations

BACKGROUND

Prospective and case-control studies have demonstrated that memory loss and executive dysfunction occur early in Alzheimer disease (AD).

OBJECTIVE

To investigate these observations by the study of persons at risk for autosomal dominant forms of AD.

METHODS

Neuropsychological and genetic tests were performed on 51 nondemented at-risk members of 10 Mexican families with two distinct presenilin-1 (PS1) mutations. Test scores were compared between PS1 mutation carriers (MCs; n = 30) and noncarriers (NCs; n = 21) by analyses of variance, co-varying for family and specific mutation. Regression analyses were performed, taking into account age relative to the median age at dementia diagnosis in the family (adjusted age), gender, Beck Depression Inventory (BDI) scores, education, and number of APOE epsilon4 alleles. Subjects were divided into age tertiles and scores compared within these groups. Composite scores for Verbal Memory, Executive Function/Working Memory, Language, and Visuospatial Function were created, and these scores compared between MCs and NCs.

RESULTS

MCs performed worse than NCs on the Mini-Mental State Examination, Trails Making Tests A and B, Delayed Recall of a 10-Word List, and Wechsler Adult Intelligence Scale WAIS Block Design. In multiple linear regression analyses, BDI score, gender, and number of APOE epsilon4 alleles did not consistently affect test scores. The differences seen between MCs and NCs were due to differences in the oldest tertile. MCs had lower Visuospatial and Executive Function/Working Memory but not Verbal Memory or Language composite scores.

CONCLUSIONS

This study is consistent with findings in sporadic Alzheimer disease of early problems with memory, visuospatial function, and particularly with executive function in PS1 mutation carriers. Depression, gender, and presence of an APOE epsilon4 allele did not demonstrate large influences on neuropsychological performance.

Female preclinical presenilin-1 mutation carriers unaware of their genetic status have higher levels of depression than their non-mutation carrying kin

OBJECTIVES

To study depressive symptoms in preclinical presenilin-1 (PS1) related Alzheimer's disease.

METHODS

Participants were 33 Mexican women at risk for inheriting PS1 mutations who were not demented. They were interviewed, underwent cognitive testing, and completed the Beck depression inventory (BDI). PS1 mutation status was determined. Mean BDI scores were compared between PS1 mutation carriers and non-carriers. The percentage of subjects who reported seeing a psychiatric professional, and the percentage complaining of memory loss were compared between groups. Regression analysis was used to determine whether mutation status predicted BDI scores after adjusting for age, education, mini-mental state examination, and subjective memory function.

RESULTS

PS1 mutation carriers (n = 17) scored significantly higher than non-carriers (n = 16) on the BDI (mean score, 14.4 v 6.5, p = 0.017); 24% of mutation carriers and 12.5% of non-carriers admitted having sought help from a psychiatric professional (NS). Mutation status remained a significant predictor of BDI scores after adjusting for potential covariates. Though not demented, mutation carriers tended to score lower than non-carriers on several neuropsychological tests.

CONCLUSIONS

Depressive symptoms can occur early in the course of PS1 related Alzheimer's disease, at least in women. This supports the hypothesis that depression may occur as a direct result of the neuropathology underlying Alzheimer's disease.

Oral versus vaginal misoprostol for cervical priming in first-trimester abortion: a randomized trial

The objective of this study was to compare the oral and vaginal administration of misoprostol for cervical priming before surgical abortion up to 63 days' gestation. A total of 900 pregnant women, with ages ranging from 18 to 42 years, who asked for pregnancy termination, were included in this study. Women were randomly allocated to one of the following groups: oral administration of 400 microg misoprostol, 8 h before aspiration; and vaginal self-administration of 400 microg misoprostol, 4 h before aspiration. During admission, all subjects were checked on a 15-min basis. The preoperative cervical dilatation achieved was the main outcome assessed. The cervix was dilated (Hegar > or = 8) in 348 (78%) subjects from the oral treatment group and in 391 (87%) women from the vaginal treatment group; this difference was statistically significant (p = 0.0004). The mean dilatation achieved in the oral treatment group was 8.1 mm (SD 1.6 mm) and it was 8.5 mm (SD 1.5 mm) in the vaginal treatment group; this difference was statistically significant (p = 0.0001). The frequencies of side-effects such as nausea, vomiting, diarrhea and chills reported by women from the vaginal misoprostol group were 10, 8, 18 and 4 times lower, respectively, than those reported by subjects from the oral misoprostol group. In conclusion, vaginal self-administration of misoprostol was the best administration route, as it obtained the same or greater priming effectiveness of the cervix in half the time with a much lower frequency of side-effects.

Disruption of hsp90 function results in degradation of the death domain kinase, receptor-interacting protein (RIP), and blockage of tumor necrosis factor-induced nuclear factor-kappaB activation

The death domain kinase, receptor interacting protein (RIP), is one of the major components of the tumor necrosis factor receptor 1 (TNFR1) complex and plays an essential role in tumor necrosis factor (TNF)-mediated nuclear factor kappaB (NF-kappaB) activation. The activation of NF-kappaB protects cells against TNF-induced apoptosis. Heat-shock proteins (Hsps) are chaperone molecules that confer protein stability and help to restore protein native folding following heat shock and other stresses. The most abundant Hsp, Hsp90, is also involved in regulating the stability and function of a number of cell-signaling molecules. Here we report that RIP is a novel Hsp90-associated kinase and that disruption of Hsp90 function by its specific inhibitor, geldanamycin (GA), selectively causes RIP degradation and the subsequent inhibition of TNF-mediated IkappaB kinase and NF-kappaB activation. MG-132, a specific proteasome inhibitor, abrogated GA-induced degradation of RIP but failed to restore the activation of IkappaB kinase by TNF, perhaps because, in the presence of GA and MG-132, RIP accumulated in a detergent-insoluble subcellular fraction. Most importantly, the degradation of RIP sensitizes cells to TNF-induced apoptosis. These data indicate that Hsp90 plays an important role in TNF-mediated NF-kappaB activation by modulating the stability and solubility of RIP. Thus, inhibition of NF-kappaB activation by GA may be a critical component of the anti-tumor activity of this drug.

The distinct roles of TRAF2 and RIP in IKK activation by TNF-R1: TRAF2 recruits IKK to TNF-R1 while RIP mediates IKK activation

The death domain kinase RIP and the TNF receptor-associated factor 2 (TRAF2) are essential effectors in TNF signaling. To understand the mechanism by which RIP and TRAF2 regulate TNF-induced activation of the transcription factor NF-kappaB, we investigated their respective roles in TNF-R1-mediated IKK activation using both RIP-/- and TRAF2-/- fibroblasts. We found that TNF-R1-mediated IKK activation requires both RIP and TRAF2 proteins. Although TRAF2 or RIP can be independently recruited to the TNF-R1 complex, neither one of them alone is capable of transducing the TNF signal that leads to IKK activation. Moreover, we demonstrated that IKK is recruited to the TNF-R1 complex through TRAF2 upon TNF treatment and that IKK activation requires the presence of RIP in the same complex.

Cleavage of the death domain kinase RIP by caspase-8 prompts TNF-induced apoptosis

Although the molecular mechanisms of TNF signaling have been largely elucidated, the principle that regulates the balance of life and death is still unknown. We report here that the death domain kinase RIP, a key component of the TNF signaling complex, was cleaved by Caspase-8 in TNF-induced apoptosis. The cleavage site was mapped to the aspartic acid at position 324 of RIP. We demonstrated that the cleavage of RIP resulted in the blockage of TNF-induced NF-kappaB activation. RIPc, one of the cleavage products, enhanced interaction between TRADD and FADD/MORT1 and increased cells' sensitivity to TNF. Most importantly, the Caspase-8 resistant RIP mutants protected cells against TNF-induced apopotosis. These results suggest that cleavage of RIP is an important process in TNF-induced apoptosis. Further more, RIP cleavage was also detected in other death receptor-mediated apoptosis. Therefore, our study provides a potential mechanism to convert cells from life to death in death receptor-mediated apoptosis.

Neuropsychological changes in subjects at risk of inheriting Alzheimer's disease

Subjects from four Mexican families at risk of inheriting Alzheimer's disease (AD) were studied using a complete neuropsychological battery. These tests were repeated and compared 1 year later. Some of the experimental subjects belong to an international protocol on molecular chromosomal study. A control group matched in age and schooling was included. The subjects at risk underwent a complete physical, neurological and neuropsychological assessment. A neuropsychological battery of cognitive domains designed for the the study of dementia syndromes was administered to all subjects. Six of the subjects showed abnormal performance in cognitive functions, memory, visuospatial functions or language which persisted 1 year later. The present work describes the initial findings of a long-term prospective study aimed at delineating the neuropsychological profile of subjects at risk and to validate subtle abnormalities which in some cases could be the incipient changes of AD.

Neurinoma of the trigeminal root and atypical trigeminal neuralgia: case report and review of the literature

BACKGROUND

Neurinomas of the trigeminal nerve are a rare entity: those located in the posterior fossa account for 20% of all cases. In the majority of cases, the clinical presentation begins with fifth cranial nerve involvement producing a constant pain associated with other cranial nerve palsy and cerebellar signs.

METHODS

We report the clinical features, neuroradiological imagings, and management of a case of trigeminal neurinoma located in the cerebellopontine angle, arising from the Vth cranial nerve root, presenting with an atypical trigeminal neuralgia; moreover, we analyze similar cases reported in the literature and we discuss whether pain can be produced by a neurinoma that arises central to the ganglion.

RESULTS

The tumor presented with an atypical trigeminal neuralgia characterized by constant trigeminal pain with paroxystical burns, hyperesthesia and hyperactive autonomic dysfunction. Neuroradiological examinations provided the best preoperative localization of this lesion, allowing better planning of the surgical approach, considering the large size of this tumor. A retromastoid incision and posterior fossa craniectomy approach was used, with complete excision of the tumor. The paraxysmal sharp pain and hyperesthesia disappeared completely, but the constant burning pain persisted although it was less intense. At an 8-month follow-up examination, the patient showed a progressive improvement of clinical symptoms and control magnetic resonance imaging (MRI) showed the complete removal of the neoplasm and the absence of residuals or recurrences.

CONCLUSION

Although in a high percentage of cases of atypical trigeminal neuralgia a neurovascular conflict might be suspected, the review of the present case suggests that the hypothesis of a trigeminal neurinoma must be investigated both with adequate neuroradiological procedures and/or microsurgical exploration of the trigeminal root.
