Prevalence and clinical implications of sarcopenia in breast cancer: a systematic review and meta-analysis.

PURPOSE: The impact of sarcopenia in oncology is increasingly recognized, yet little is known about its clinical implications in breast cancer. This systematic review and meta-analysis estimates the overall prevalence of sarcopenia in breast cancer, quantifies skeletal muscle index (SMI), and comprehensively evaluates sarcopenia's impact on clinical outcomes. METHODS: We systematically searched primary original research published before June 2023 in four databases: the Cochrane Library via Wiley, CINAHL Plus with Full Text, Embase via Elsevier Excerpta Medica, and Medline via Ovid. Standardized mean SMI and 95% confidence interval (CI) were calculated by applying the random-effects model. The methodological quality of the included studies was assessed using the National Institutes of Health quality assessment checklist. RESULTS: The systematic review included 17 studies with a total of 9863 patients; the meta-analysis included 12 of these studies. The mean prevalence of sarcopenia in breast cancer (stages I-III) was 32.5%. The mean SMI assessed by CT was 43.94 cm2/m2 (95% CI 42.87, 45.01; p < .01). Overall, low muscle mass was associated with chemotherapy toxicities, dose reductions, dose delays, or treatment discontinuation. Low muscle mass was generally associated with poor survival, but in some studies, this association was not significant or reversed direction. CONCLUSION: Sarcopenia is not just a state of muscle mass loss, but an influencing factor on therapeutic effects and survival rates in oncology. It is thus necessary to recognize the risk of sarcopenia throughout the trajectory of cancer treatment, identify low muscle mass early, and manage it from a prehabilitation perspective.

A network analysis of pain intensity and pain-related measures of physical, emotional, and social functioning in US military service members with chronic pain.

OBJECTIVE: The purpose of this study was to apply network analysis methodology to better understand the relationships between pain-related measures among people with chronic pain. METHODS: We analyzed data from a cross-sectional sample of 4614 active duty service members with chronic pain referred to 1 military interdisciplinary pain management center between 2014 and 2021. Using a combination of Patient-Reported Outcomes Measurement Information System measures and other pain-related measures, we applied the "EBICglasso" algorithm to create regularized partial correlation networks that would identify the most influential measures. RESULTS: Pain interference, depression, and anxiety had the highest strength in these networks. Pain catastrophizing played an important role in the association between pain and other pain-related health measures. Bootstrap analyses showed that the networks were very stable and the edge weights accurately estimated in 2 analyses (with and without pain catastrophizing). CONCLUSIONS: Our findings offer new insights into the relationships between symptoms using network analysis. Important findings highlight the strength of association between pain interference, depression and anxiety, which suggests that if pain is to be treated depression and anxiety must also be addressed. What was of specific importance was the role that pain catastrophizing had in the relationship between pain and other symptoms suggesting that pain catastrophizing is a key symptom on which to focus for treatment of chronic pain.

Feasibility of In-Home Virtual Reality for Chronic Pain in Sickle Cell Disease.

PURPOSE: This study assessed the feasibility of an in-home virtual reality intervention for chronic pain in adults with sickle cell disease. DESIGN: Two-group, parallel, randomized, multiple methods design with surveys, and interviews. METHODS: Participants were randomized to virtual reality or audio control, with 2-16-minute daily modules for 8 weeks, a daily pain diary survey, and a post study interview. Chronic pain and pain correlates were evaluated at baseline and every 4 weeks for 3 months. Feasibility outcomes were participant enrollment (set at > 50%), questionnaire response (> 50%), intervention use, and cybersickness (< 20%). RESULTS: Of the individuals approached, 67.8% (n = 19) were enrolled. Questionnaire response rates were 100% at baseline, 57.8% at week 4, and < 50% at weeks 8 and 12. The intervention was used for a median of 781 minutes and 210 minutes in the virtual reality and audio groups, respectively. Participants reported slight symptoms of cybersickness with no reports of severe symptoms, and the intervention was acceptable. CONCLUSIONS: Home-based virtual reality can be used in future sickle cell disease research. To further strengthen evaluations of virtual reality in adults with sickle cell who experience chronic pain, future trials should address sample size limitations and incorporate recommended strategies to address cybersickness and questionnaire response. CLINICAL IMPLICATIONS: The first known application of in-home virtual reality for chronic pain in adults with sickle cell disease was successful. Findings can inform future in-home investigations of virtual reality in this underserved population.

A Scoping Review of Social Determinants of Health and Pain Outcomes in Sickle Cell Disease.

BACKGROUND: Sickle cell disease (SCD) is a hereditary blood disorder with chronic pain that affects over 100,000 people in the United States. Previous research suggests a complex interaction between SCD pain outcomes and social determinants of health (SDOH). OBJECTIVE: To explore the impact of SDOH on pain outcomes in SCD. DESIGN: We used a scoping review design to explore the broad topic of social factors that affect SCD pain. DATA SOURCES: We searched the PubMed/MEDLINE, CINAHL, and Embase databases using combined search and Medical Subject Headings terms ("social determinants of health," "sickle cell," and "pain"). REVIEW METHODS: We used a content analysis with a summative approach to identify and describe interactions between SDOH and SCD pain outcomes. FINDINGS: Eight articles reporting studies with 7,992 total participants and a focus on SCD pain outcomes met the inclusion criteria. Three themes related to SDOH and pain were produced: education and employment, social and emotional functioning, and healthcare access. CONCLUSION: The key findings highlight the complex interplay between socioeconomic, psychological, and biological factors in SCD pain experiences. This underscores the need for nursing care to consider SDOH in an integrated, holistic approach to SCD pain. IMPLICATIONS FOR NURSING: To improve pain management among their SCD patients, nurses can assess pain holistically, develop customized individual pain management plans with educational and health literacy support options, and strengthen social support.

An Intervention to Reduce Sedentary Behavior in Adults with Chronic Kidney Disease: A Feasibility Study.

Adults with chronic kidney disease (CKD) tend to be extremely sedentary. We investigated the feasibility and acceptability of a sedentary-reducing intervention for adults with CKD. The intervention utilized telephone-delivered coaching and a consumer wearable device to support participants to reduce their sedentary time. The mean age of participants in the sample was 60.5 years; 72% were women, and 83% had CKD Stage 3. At baseline, participants spent 73% of their waking time sedentary. Inter vention phone call attendance was 100%, study retention was 82%, and the intervention was rated as enjoyable (9.1/10). A telephone-delivered, sedentary-reducing intervention is feasible and acceptable in adults with CKD. Future work is needed investigating the efficacy of sedentary-reducing interventions for adults with CKD.

Hematologic toxicities, sarcopenia, and body composition change in breast cancer patients undergoing neoadjuvant chemotherapy.

PURPOSE: Evaluation of body composition and sarcopenia status could provide evidence for more sensitive prediction of chemotherapy toxicities and support mitigation of the negative impacts of chemotherapy. This study evaluated associations among hematologic toxicities, sarcopenia, and body composition change in breast cancer patients undergoing neoadjuvant chemotherapy. METHODS: This retrospective cohort study employed data from 298 breast cancer patients undergoing neoadjuvant chemotherapy. We evaluated two abdominal computed tomography scans before and after neoadjuvant chemotherapy to identify body composition change. As hematologic toxicities, severe (grade 3 or 4) anemia, neutropenia, and thrombocytopenia were assessed throughout the treatment period using Common Terminology Criteria for Adverse Events (version 5.0). RESULTS: Participants experienced severe neutropenia (23.5%), anemia (7.1%), and thrombocytopenia (0.7%) during chemotherapy. After chemotherapy, the group with sarcopenia had double the anemia prevalence of the group without sarcopenia (p < 0.001). The group with anemia had significantly decreased skeletal muscle index (SMI, p = .0013) and subcutaneous fat index (SFI, p = .0008). Almost 50% of the sarcopenia group treated with an AC-T (weekly) regimen (combined anthracycline and cyclophosphamide followed by a weekly taxane) had neutropenia. Multiple logistic regression showed that the AC-T (weekly) group had higher neutropenia prevalence than other regimen groups. CONCLUSION: Our findings of higher anemia prevalence in breast cancer patients with sarcopenia and decreased SMI and SFI after neoadjuvant chemotherapy provide evidence of a relationship between anemia and body composition change. Early screening and combined consideration of body composition change, sarcopenia status, and chemotherapy regimen could improve clinical outcomes.

Integration of Person-Centered Narratives Into the Electronic Health Record.

BACKGROUND: Care delivery that is not person-centered has been called discordant care . There has been a shift to incorporate more of a person's narrative into their individual healthcare treatment plan to reduce discordant care. Aligning with this shift in healthcare delivery, we developed a person-centered narrative intervention (PCNI) to address existing gaps in delivery of person-centered care. OBJECTIVES: This study aimed to evaluate the feasibility of conducting a randomized study and describe the outcomes of PCNI to usual care on the following person (patient)-reported outcomes: perceptions of the quality of communication with their nurses and their psychosocial and existential well-being. METHODS: This study's design was an Obesity-Related Behavioral Intervention Trials model Phase II proof-of-concept randomized study. The participants were people admitted to an acute care hospital diagnosed with heart failure and/or end-stage renal disease. RESULTS: Despite COVID-19 challenges, the PCNI was feasible in an acute care setting; it showed a moderate positive difference between conditions in the person's perception of their quality of communication and a small positive difference in their perception of feeling heard and understood. For our secondary outcomes of anxiety, depression, and psychosocial illness effect, there were small or no effects in the acute care setting. DISCUSSION: Using a person-centered narrative, such as the PCNI, can help inform delivery of care that incorporates a person's (patient's) beliefs, values, and preferences into their healthcare. This study used a pragmatic approach to evaluate the PCNI in real time in an acute care setting to assess patient-reported outcomes. These positive results in a small sample indicate the need for continued testing of the PCNI. These promising effects require further testing in a Phase III efficacy study within a larger randomized controlled clinical trial.

The Relationship Between Duration of Stay and Self-rated Health Among International College Students in South Korea.

This study examined relationships between duration of stay and self-rated health among international students in South Korea and compared participants' health-related characteristics according to duration of stay. The study recruited a convenience sample of 165 international students enrolled in undergraduate or graduate programs. For this cross-sectional, descriptive study, participants were recruited at one South Korean university. Data were subjected to ordinal logistic regression analyses. After controlling for covariates, a stay of 6 months or less was a significant predictor of better self-rated health. Compared to those in their first semester, international students staying more than 6 months more frequently experienced short sleep duration, physical health symptoms, healthcare utilization, unmet healthcare needs, and perceived discrimination. Study findings indicate that international students' health tends to deteriorate after their first semester. To promote the health and academic success of international students, universities should provide timely health promotion programs.

The Role of Psychological Factors in Chronic Pain Treatment Outcomes in the Military.

PURPOSE: Chronic pain treatment in the military includes complementary and integrative health (CIH) therapies that may affect psychological factors such as pain catastrophizing, chronic pain acceptance, pain self-efficacy, and patient activation. The unique roles that psychosocial factors play in how CIH approaches reduce pain are not clear. This study examined if a holistic pain management program improved pain outcomes through psychological mediators in service members with chronic pain. DESIGN: Secondary analysis of a clinical trial. METHODS: Active-duty service members (n = 210) were randomly assigned to a 3-week course of standard rehabilitative care or standard rehabilitative care combined with CIH therapies. Both treatments were followed by a 3-week functional restoration program. Study measures were completed pre- and post-treatment using the Military Health System's Pain Assessment Screening Tool and Outcomes Registry. Mediation analyses tested the indirect effects of the change in psychological factors before functional restoration on the change in pain impact (e.g., pain intensity, pain interference, functional status) after functional restoration. RESULTS: All psychological factors except for chronic pain acceptance were related to improved pain impact (p<.05). Furthermore, a change in psychological factors prior to functional restoration was related to the change in pain impact after functional restoration. However, the addition of CIH therapies to standard rehabilitative care did not result in changes in pain outcomes mediated by the psychological factors. CONCLUSIONS: Although psychological factors were related to pain outcomes, the effect of CIH therapies on chronic pain did not occur via a change in the four psychological factors.

Tryptophan and Kynurenine Pathway Metabolites and Psychoneurological Symptoms Among Breast Cancer Survivors.

BACKGROUND: Among breast cancer survivors, pain, fatigue, depression, anxiety, and sleep disturbance are common psychoneurological symptoms that cluster together. Inflammation-induced activation of the tryptophan-kynurenine metabolomic pathway may play an important role in these symptoms. AIMS: This study investigated the relationship between the metabolites involved in the tryptophan-kynurenine pathway and psychoneurological symptoms among breast cancer survivors. DESIGN: Cross-sectional study. SETTING: Participants were recruited at the oncology clinic at the University of Illinois Hospital & Health Sciences System. PARTICIPANTS/SUBJECTS: 79 breast cancer survivors after major cancer treatment. METHODS: We assessed psychoneurological symptoms with the PROMIS-29 and collected metabolites from fasting blood among breast cancer survivors after major cancer treatment, then analyzed four major metabolites involved in the tryptophankynurenine pathway (tryptophan, kynurenine, kynurenic acid, and quinolinic acid). Latent profile analysis identified subgroups based on the five psychoneurological symptoms. Mann-Whitney U tests and multivariable logistic regression compared targeted metabolites between subgroups. RESULTS: We identified two distinct symptom subgroups (low, 81%; high, 19%). Compared with participants in the low symptom subgroup, patients in the high symptom subgroup had higher BMI (p = .024) and were currently using antidepressants (p = .008). Using multivariable analysis, lower tryptophan levels (p = .019) and higher kynurenine/tryptophan ratio (p = .028) were associated with increased risk of being in the high symptom subgroup after adjusting for BMI and antidepressant status. CONCLUSION: The tryptophan-kynurenine pathway and impaired tryptophan availability may contribute to the development of psychoneurological symptoms.

Pain Interference in End Stage Kidney Disease is Associated with Changes in Gut Microbiome Features Before and After Kidney Transplantation.

BACKGROUND: Pain, a common debilitating symptom among kidney transplant recipients (KTRs), is among the most common and undertreated symptoms after kidney transplantation. AIMS: Characterize associations between gut microbiome features and pain interference before and after kidney transplantation. DESIGN: Longitudinal, repeated measures study, collecting fecal specimens and pain interference data pretransplant and 3 months posttransplant. SETTING: Participants were recruited at the kidney transplant clinic at the University of Illinois Hospital & Health Sciences System. PARTICIPANTS/SUBJECTS: 19 living donor kidney transplant recipients. METHODS: We assessed fecal microbial community structure with shotgun metagenomic sequencing; we used pain interference scores derived from the Patient-Reported Outcomes Measurement Information System-57. RESULTS: We measured a reduction in the Shannon diversity index in both groups after transplantation but observed no significant differences between groups at either time point. We did observe significant differences in fecal microbial Bray-Curtis similarity index among those reporting pain interference pre- transplant versus no pain interference at 3-months posttransplant (R = .306, p = .022), and between pain interference groups at posttransplant (R = .249, p = .041). Pairwise models showed significant differences between groups posttransplant in relative abundances of several taxa, including a 5-fold reduction.ßin Akkermansia among those with pain interference and a higher relative abundance of taxa associated with chronic inflammation in those with pain interference posttransplant. Functional gene analysis identified two features that were significantly enriched in those with pain interference, including a peptide transport system gene. CONCLUSIONS: Gut microbiota community structure differs between groups with and without pain interference at 3 months after kidney transplantation. Several taxa involved in intestinal barrier integrity and chronic inflammation were associated with posttransplant pain.

Community-based death preparation and education: A scoping review.

The COVID-19 pandemic revealed a need for people and communities for death preparation. Few studies have examined community-level interventions for death preparation and education. This scoping review scrutinized the relevant literature following PRISMA 2018 guidelines. Six databases were searched for articles published between 2010 and 2020. We found that cultural, socioeconomic, and individual values affected death preparation and that online courses and life-death education were effective preparation methods. Additional research is needed to identify the population-specific effectiveness of interventions. To fully investigate death preparation and education at the community level, theory-based studies employing quantitative and qualitative methods are also needed.

Hypnosis and relaxation interventions for chronic pain management in cancer survivors: a randomized controlled trial.

PURPOSE: Nonpharmacological interventions such as hypnosis show promising evidence for the self-management of pain and pain-related sequelae among cancer survivors. The purpose of this study was to evaluate the efficacy of a 4-week recorded hypnosis intervention in reducing pain intensity compared to a recorded relaxation intervention in cancer survivors with chronic pain. METHODS: Adult cancer survivors were randomly assigned to listen to hypnosis (n = 55) or relaxation recordings (n = 54) daily for 28 days. Primary (pain intensity) and secondary outcomes (pain interference, anxiety, depression, fatigue, sleep disturbance) measures were completed pre- and post-treatment. Treatment effects were evaluated using a series of analyses of covariance. RESULTS: Both hypnosis and relaxation provided significant and moderate to large improvements in the primary outcome and the secondary outcomes of pain interference and anxiety (ds = 0.44-0.88). The hypnosis group also experienced a moderate improvement in fatigue (d = 0.47) and sleep disturbance (d = 0.54). The effect size for pain reduction from pre- to post-treatment for the hypnosis group was d = 0.86 and for the relaxation group, d = 0.88. There were no significant between-group differences in primary and secondary outcomes from pre- to post-treatment. CONCLUSIONS: The results support that recorded hypnosis and relaxation interventions are similarly effective in reducing pain and the pain-related sequelae of pain interference and anxiety among cancer survivors with chronic pain. The hypnosis intervention also reduced fatigue and sleep disturbance. Audio recordings can provide a convenient delivery method of nonpharmacological interventions to self-manage chronic pain. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03867760, registered March 8, 2019.

Experiences of Military Primary Care Providers During Chronic Pain Visits: A Qualitative Descriptive Study.

OBJECTIVE: Chronic pain complaints are the second most common reason for outpatient primary care visits, yet a comprehensive assessment of the processes and experiences of providers during a chronic pain visit is still lacking. This qualitative descriptive study aimed to conceptualize the processes and experiences that military primary care providers go through while they assess and manage chronic pain. SETTING: Single U.S. Army medical center. METHODS: Semistructured interviews with 12 military primary care providers. Interviews were audio-recorded, transcribed, and coded with the use of qualitative software. Transcripts were analyzed with thematic analysis to identify emergent themes. RESULTS: Three broad themes with associated subthemes captured the processes and the providers' experiences: 1) comprehending the pain story-asking the right questions about pain impact, navigating through the complexities of the pain story, and conveying understanding of the pain story back to the patient; 2) optimizing the pain story-perceiving provider-patient disconnect on pain management goals, resetting realistic goals, creating an optimal individualized treatment plan, and evaluating treatment effectiveness; and 3) empathetic and therapeutic engagement with patients-trusting patients and fostering the patient-provider relationship. A thematic map illustrates these provider experiences. CONCLUSIONS: During chronic pain visits, the provider-patient disconnect on the goals of chronic pain treatment presents a considerable challenge. Further in-depth studies on addressing provider-patient disconnect are warranted to identify solutions, which would help providers communicate realistic chronic pain management expectations to patients. The themes and subthemes described in this study could serve as a guide for directing strategies to improve chronic pain visits in primary care.

Use of Complementary and Integrative Health Therapies Before Intensive Functional Restoration in Active Duty Service Members with Chronic Pain.

OBJECTIVE: Psychosocial factors are known to predict chronic pain, and the use of complementary and integrative health (CIH) therapies to address pain is emerging among the military population. However, conflicting results on pain outcomes warrant additional research. This study aimed to 1) evaluate the benefit of adding a CIH pain management program to standard rehabilitative care (SRC), as compared with SRC alone, as a precursor to an intensive functional restoration (FR) program; 2) identify factors that predict improvement in pain outcomes after treatment; and 3) determine the proportion of participants who experience a clinically meaningful response. DESIGN: Pragmatic randomized controlled clinical trial. Participants were randomized to a 3-week course of either SRC alone or SRC+CIH (stage 1), followed by a 3- to 6-week course of FR (stage 2). SUBJECTS: Active duty service members with chronic pain. METHODS: Participants completed either SRC alone or SRC+CIH (stage 1), followed by a course of FR (stage 2). Patient-reported and provider-determined outcomes were collected at baseline, after stage 1, and after stage 2. A covariance pattern model with an unstructured residual covariance matrix was used to compare treatment arms while accounting for dependency due to repeated measurements. RESULTS: A total of 210 service members participated. Most were in the Army (82%) and were male (84%). Participants randomized to the SRC+CIH intervention had greater improvement in the pain impact score than did those in the SRC-alone group. Predictors of outcomes were baseline impact score, anger, depression, and educational status. CONCLUSIONS: This study found that military service members with the highest pain impact benefit the most from interdisciplinary pain care.

Acute and Posttraumatic Stress in Family Members of Children With a Prolonged Stay in a PICU: Secondary Analysis of a Randomized Trial.

OBJECTIVES: To identify the prevalence of screening criteria for acute and posttraumatic stress disorders (PTSDs) and stress symptoms among family members of children in the PICU for more than 8 days and examine risk factors for stress symptoms. DESIGN: Secondary analysis of data from a randomized trial of a palliative care intervention conducted between 2010 and 2014. SETTING: An urban pediatric hospital in Seattle, WA. SUBJECTS: The sample included 377 family members of 220 children. INTERVENTIONS: Family Communication Study. MEASUREMENTS AND MAIN RESULTS: Outcomes were symptom scores and diagnostic screening criteria for acute stress disorder (ASD) and PTSD. Predictors included demographic- and admission-related characteristics and hypothesized risk factors for developing stress-related mental health disorders. The mean score for acute stress symptoms during the ICU stay was 40.3 (sd = 13.8) and 59 family members in total met diagnostic screening criteria for ASD during hospitalization (15.6%). At 3-month follow-up, the mean score for posttraumatic stress symptoms was 30.8 (sd = 12.9) and 52 family members met diagnostic criteria for PTSD (13.8%). Factors associated with meeting ASD screening criteria were unplanned admission and poorer family relationships. Factors associated with PTSD symptoms and diagnosis were longer length of stay, meeting ASD criteria during admission, child's death, and less perceived social support. CONCLUSIONS: Meeting screening criteria for PTSD was associated with demographic, length of stay, and family relationships among family members of seriously ill children. PTSD outcomes were higher among family members whose child died. This study helps identify risk factors that can be used to target needed psychosocial screening, monitoring and support during and following a prolonged PICU admission, as well as family-centered interventions and supportive bereavement intervention for the family members of a deceased child.

Funeral Experience in South Korea: A Phenomenological Study.

Few studies of death preparation in South Korea are available. This article describes South Koreans' experiences of death and a funeral in a hospital setting to improve health care providers' ability to care for dying patients and their family. Using Colaizzi's phenomenological method, we conducted semistructured interviews with 40 South Koreans who had lost a family member in a hospital setting. Participants' statements were classified into 12 themes, 5 theme clusters, and 3 categories: (a) vagueness of funeral culture, (b) distortion of meaning in funeral culture, and (c) the need to prepare for death and process grief. Our findings are relevant to hospital-based health care providers who care for dying patients and their family. Targeted educational information could help health care providers better serve patients and family. Policy changes could improve quality of care by allowing health care providers to transition with the family from hospital units to a hospital-based funeral setting.

Sharing genetic test results of germline pathogenic variants of hereditary cancer with relatives: A single-center cross-sectional study.

OBJECTIVE: This study aimed to determine whether Japanese cancer patients share test results of germline pathogenic variants of hereditary cancer with their relatives. METHODS: This single-center cross-sectional study enrolled 21 Japanese patients who received results of germline pathogenic variants of hereditary cancer at least 6 months prior. RESULTS: All patients shared their test results with at least one relative, with the following sharing rates: 85.7% for first-degree relatives, 10% for second-degree relatives and 8.3% for third-degree relatives. Patients most commonly shared the information with their children aged >18 years (86.7%), followed by their siblings (73.6%), spouses (64.7%) and parents (54.5%). Three categories were extracted from qualitative analysis: 'characteristics of my cancer', 'knowledge and caution about inheritability' and 'utilization of medical care.' CONCLUSIONS: The rate of test result sharing with first-degree relatives was comparable with those in Europe and the USA. Patients with germline pathogenic variants also tended to share their test results more with their children and siblings than with their parents. Informing their relatives of the results was suggestive of the motivation to influence their relatives' health outcome and contribute to the well-being of their children and siblings.

Characteristics of taste alterations in people receiving taxane-based chemotherapy and their association with appetite, weight, and quality of life.

PURPOSE: There is limited evidence on the effect of chemotherapy-associated taste alteration. This study aimed to evaluate taste alteration characteristics in patients receiving taxane-based chemotherapy and investigate the association of taste alterations with appetite, weight, quality of life (QOL), and adverse events. METHODS: This cross-sectional study evaluated 100 patients receiving paclitaxel, docetaxel, or nab-paclitaxel as monotherapy or combination therapy. Taste alterations were evaluated using taste recognition thresholds and severity and symptom scales. Taste recognition thresholds, symptoms, appetite, weight, and adverse events were compared between patients with and without taste alterations, and logistic regression analysis was performed to identify risk factors. RESULTS: Of the 100 patients, 59% reported taste alterations. We found significantly elevated taste recognition thresholds (hypogeusia) for sweet, sour, and bitter tastes in the taste alteration group receiving nab-paclitaxel (p = 0.022, 0.020, and 0.039, respectively). The taste alteration group reported general taste alterations, decline in basic taste, and decreased appetite. Neither weight nor QOL was associated with taste alterations. Docetaxel therapy, previous chemotherapy, dry mouth, and peripheral neuropathy were significantly associated with taste alterations. CONCLUSIONS: Almost 60% of patients receiving taxane-based regimens, especially docetaxel, reported taste alterations. Taste alteration affected the patient's appetite but did not affect the weight or QOL. Docetaxel therapy, previous chemotherapy, dry mouth, and peripheral neuropathy were independent risk factors for taste alterations.

Relationship Between Post-Traumatic Stress Disorder Symptoms and Chronic Pain-Related Symptom Domains Among Military Active Duty Service Members.

OBJECTIVE: This study examined the relationships between symptom domains relevant to post-traumatic stress disorder (PTSD) diagnosis, PTSD screening, and chronic pain-related symptoms (pain intensity, pain interference, physical function, fatigue, depression, anxiety, anger, satisfaction with social roles) experienced by active duty military service members with chronic pain. DESIGN: ross-sectional study. SETTING: This study was conducted at the Interdisciplinary Pain Management Center (IPMC) at Madigan Army Medical Center between 2014 and 2018. SUBJECTS: Active duty service members receiving care at IPMC (n = 2745) were included in this study. METHODS: Independent sample t test was conducted to compare pain intensity and pain-related measures of physical, emotional, and social functioning among patients with and without a PTSD diagnosis or PTSD positive screen (≥3 symptoms). Relative weight analysis was used to identify the relative importance of each PTSD symptom cluster (e.g., intrusion, avoidance, hyperarousal, emotional numbness) to pain and related domains. RESULTS: Approximately 27.9% of the patients had a positive screen for PTSD, and 30.5% of the patients had a PTSD diagnosis. Patients with PTSD diagnosis and positive screening had higher pain interference and lower physical function and social satisfaction scores (P < 0.001) and had increased anger, anxiety, fatigue, and depression scores (P < 0.001). Emotional numbness accounted for the largest proportion of variance in average pain intensity, pain interference, and psychological functioning, and avoidance accounted for the largest proportion of variance in physical function. CONCLUSION: To improve treatment effectiveness and overall functioning for active duty military patients, integrated treatment and therapies targeted to reducing chronic pain and PTSD symptoms (focus on emotional numbness and avoidance) are recommended.
