Sexual health among adolescent and young adult cancer survivors: A scoping review from the Children's Oncology Group Adolescent and Young Adult Oncology Discipline Committee.

Sexual function is a vital aspect of quality of life among adolescent and young adult (AYA) (ages 15-39 years) cancer survivors. Sexual function encompasses physical, psychosocial, and developmental factors that contribute to sexual health, all of which may be negatively impacted by cancer and treatment. However, limited information is available to inform the care of AYA cancer survivors in this regard. This scoping review, conducted by the Children's Oncology Group AYA Oncology Discipline Committee, summarizes available literature regarding sexual function among AYA cancer survivors, including relevant psychosexual aspects of romantic relationships and body image. Results suggest that, overall, AYA cancer survivors experience a substantial burden of sexual dysfunction. Both physical and psychosocial sequelae influence survivors' sexual health. Interventions to support sexual health and psychosexual adjustment after cancer treatment are needed. Collaborations between the Children's Oncology Group and adult-focused cooperative groups within the National Cancer Institute's National Clinical Trials Network are warranted to advance prospective assessment of sexual dysfunction and test interventions to improve sexual health among AYA cancer survivors.

A Longitudinal Analysis of Memory Immune Responses in Convalescent Crimean-Congo Hemorrhagic Fever Survivors in Uganda.

Evaluating the adaptive immune responses to natural infection with Crimean-Congo hemorrhagic fever (CCHF) virus (CCHFV) in human survivors is critical to the development of medical countermeasures. However, the correlates of protection are unknown. As the most prevalent tick-borne human hemorrhagic fever virus with case fatality rates of 5%-30% and worldwide distribution, there is an urgent need to fill these knowledge gaps. Here, we describe adaptive immune responses in a cohort of Ugandan CCHF survivors via serial sampling over 6 years. We demonstrate persistent antibodies after infection and cross-neutralization against various clades of authentic CCHFV, as well as potent effector function. Moreover, we show for the first time persistent, polyfunctional antigen-specific memory T-cell responses to multiple CCHFV proteins up to 9 years after infection. Together, this data provides immunological benchmarks for evaluating CCHFV medical countermeasures and information that can be leveraged toward vaccine immunogen design and viral target identification for monoclonal antibody therapies.

Ebola Virus-Specific Neutralizing Antibody Persists at High Levels in Survivors 2 Years After Resolution of Disease in a Sierra Leonean Cohort.

Ebola virus (EBOV) infection results in Ebola virus disease (EVD), an often severe disease with a nonspecific presentation. Since its recognition, periodic outbreaks of EVD continue to occur in sub-Saharan Africa. The 2013-2016 West African EVD outbreak was the largest recorded, resulting in a substantial cohort of EVD survivors with persistent health complaints and variable immune responses. In this study, we characterize humoral immune responses in EVD survivors and their contacts in Eastern Sierra Leone. We found high levels of EBOV IgG in EVD survivors and lower yet substantial antibody levels in household contacts, suggesting subclinical transmission. Neutralizing antibody function was prevalent but variable in EVD survivors, raising questions about the durability of immune responses from natural infection with EBOV. Additionally, we found that certain discrete symptoms-ophthalmologic and auditory-are associated with EBOV IgG seropositivity, while an array of symptoms are associated with the presence of neutralizing antibody.

Infrared laser moxibustion for cancer-related fatigue in breast cancer survivors: a randomized controlled trial.

BACKGROUND: Cancer-related fatigue (CRF) is a pervasive, persistent, and distressing symptom experienced by cancer patients, for which few treatments are available. We investigated the efficacy and safety of infrared laser moxibustion (ILM) for improving fatigue in breast cancer survivors. METHODS: A three-arm, randomized, sham-controlled clinical trial (6-week intervention plus 12-week observational follow-up) was conducted at a tertiary hospital in Shanghai, China. The female breast cancer survivors with moderate to severe fatigue were randomized 2:2:1 to ILM (n = 56) sham ILM (n = 56), and Waitlist control (WLC)(n = 28) groups. Patients in the ILM and sham ILM (SILM) groups received real or sham ILM treatment, 2 sessions per week for 6 weeks, for a total of 12 sessions. The primary outcome was change in the Brief Fatigue Inventory (BFI) score from baseline to week 6 with follow-up until week 18 assessed in the intention-to-treat population. RESULTS: Between June 2018 and July 2021, 273 patients were assessed for eligibility, and 140 patients were finally enrolled and included in the intention-to-treat analysis. Compared with WLC, ILM reduced the average BFI score by 0.9 points (95% CI, 0.3 to 1.6, P = .007) from baseline to week 6, with a difference between the groups of 1.1 points (95% CI, 0.4 to 1.8, P = .002) at week 18. Compared with SILM, ILM treatment resulted in a non-significant reduction in the BFI score (0.4; 95% CI, -0.2 to 0.9, P = .206) from baseline to week 6, while the between-group difference was significant at week 18 (0.7; 95% CI, 0.2 to 1.3, P = .014). No serious adverse events were reported. CONCLUSION: While ILM was found to be safe and to significantly reduce fatigue compared with WLC, its promising efficacy against the sham control needs to be verified in future adequately powered trials.

Long-term health-related quality of life in head and neck cancer survivors: A large multinational study.

Head and neck cancer (HNC) patients suffer from a range of health-related quality of life (HRQoL) issues, but little is known about their long-term HRQoL. This study explored associations between treatment group and HRQoL at least 5 years' post-diagnosis in HNC survivors. In an international cross-sectional study, HNC survivors completed the European Organization for Research and Treatment of Cancer (EORTC) quality of life core questionnaire (EORTC-QLQ-C30) and its HNC module (EORTC-QLQ-H&N35). Meaningful HRQoL differences were examined between five treatment groups: (a) surgery, (b) radiotherapy, (c) chemo-radiotherapy, (d) radiotherapy ± chemotherapy and neck dissection and (e) any other surgery (meaning any tumour surgery that is not a neck dissection) and radiotherapy ± chemotherapy. Twenty-six sites in 11 countries enrolled 1105 survivors. They had a median time since diagnosis of 8 years, a mean age of 66 years and 71% were male. After adjusting for age, sex, tumour site and UICC stage, there was evidence for meaningful differences (10 points or more) in HRQoL between treatment groups in seven domains (Fatigue, Mouth Pain, Swallowing, Senses, Opening Mouth, Dry Mouth and Sticky Saliva). Survivors who had single-modality treatment had better or equal HRQoL in every domain compared to survivors with multimodal treatment, with the largest differences for Dry Mouth and Sticky Saliva. For Global Quality of Life, Physical and Social Functioning, Constipation, Dyspnoea and Financial Difficulties, at least some treatment groups had better outcomes compared to a general population. Our data suggest that multimodal treatment is associated with worse HRQoL in the long-term compared to single modality.

Inverse Probability Weighting to Estimate Impacts of Hypothetical Occupational Limits on Radon Exposure to Reduce Lung Cancer.

Radon is a known cause of lung cancer. Protective standards for radon exposure are derived largely from studies of working populations that are prone to healthy worker survivor bias. This bias can lead to under-protection of workers and is a key barrier to understanding health effects of many exposures. We apply inverse probability weighting to study a set of hypothetical exposure limits among 4,137 male, White and American Indian radon-exposed uranium miners in the Colorado Plateau followed from 1950 to 2005. We estimate cumulative risk of lung cancer through age 90 under hypothetical occupational limits. We estimate that earlier implementation of the current US Mining Safety and Health Administration annual standard of 4 working level months (implemented here as a monthly exposure limit) could have reduced lung cancer mortality from 16/100 workers to 6/100 workers (95% confidence intervals: 3/100, 8/100), in contrast with previous estimates of 10/100 workers. Our estimate is similar to that among contemporaneous occupational cohorts. Inverse probability weighting is a simple and computationally efficient way address healthy worker survivor bias in order to contrast health effects of exposure limits and estimate the number of excess health outcomes under exposure limits at work.

Association between physical activity changes and risk of incident ischemic stroke following cancer diagnosis: A nationwide retrospective cohort study.

BACKGROUND: Physical inactivity is prevalent after cancer treatment, which could increase ischemic stroke risk in cancer survivors. This study investigated the association between physical activity change from pre- to post-diagnosis and ischemic stroke risk among cancer survivors. METHODS: Using data from the Korean National Health Insurance Service database, 269,943 cancer survivors (mean [SD] age, 56.3 [12.1] years; 45.7% male) with no history of cardiovascular disease were evaluated based on changes in physical activity from pre- to post-diagnosis. Using the Fine-Gray model, subdistribution hazard ratios (sHRs) and 95% confidence intervals (CIs) for ischemic stroke risk were calculated, considering death as a competing risk. RESULTS: After cancer diagnosis, 62.0% remained inactive, 10.1% remained active, 16.6% became active, and 11.4% became inactive. During a mean (SD) follow-up of 4.1 (2.0) years, being active both pre- and post-diagnosis was associated with a 15% decreased risk of ischemic stroke (sHR, 0.85; 95% CI, 0.75-0.96), compared with those who remained inactive. Cancer survivors who became active and inactive post-diagnosis showed a 16% and 11% lower ischemic stroke risk (sHR, 0.84; 95% CI, 0.75-0.93; sHR, 0.89; 95% CI, 0.79-0.99), respectively, than those who remained inactive. Analysis by the primary cancer site did not substantially differ from the main findings. CONCLUSIONS: Physical activity is associated with reduced ischemic stroke risk among cancer survivors. The potential benefits of physical activity are not limited to individuals who were physically active before cancer diagnosis, thus preventive strategies against ischemic stroke should emphasize physical activity throughout the cancer journey.

Assisted reproductive technology use and outcomes in childhood cancer survivors.

BACKGROUND: Treatment exposures for childhood cancer reduce ovarian reserve. However, the success of assisted reproductive technology (ART) among female survivors is not well established. METHODS: Five-year survivors of childhood cancer in the Childhood Cancer Survivor Study were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System, which captures national ART outcomes. The authors assessed the live birth rate, the relative risk (RR) with 95% confidence intervals (95% CIs), and associations with treatment exposure using generalized estimating equations to account for multiple ovarian stimulations per individual. Siblings from a random sample of survivors were recruited to serve as a comparison group. RESULTS: Among 9885 female survivors, 137 (1.4%; median age at diagnosis, 10 years [range, 0-20 years]; median years of follow-up after age 18 years, 11 years [range, 2-11 years]) underwent 224 ovarian stimulations using autologous or donor eggs and/or gestational carriers (157 autologous ovarian stimulation cycles, 67 donor ovarian stimulation cycles). In siblings, 33 (1.4%) underwent 51 autologous or donor ovarian stimulations. Of those who used embryos from autologous eggs without using gestational carriers, 97 survivors underwent 155 stimulations, resulting in 49 live births, for a 31.6% chance of live birth per ovarian stimulation (vs. 38.3% for siblings; p = .39) and a 43.9% chance of live birth per transfer (vs. 50.0%; p = .33). Prior treatment with cranial radiation therapy (RR, 0.44; 95% CI, 0.20-0.97) and pelvic radiation therapy (RR, 0.33; 95% CI, 0.15-0.73) resulted in a reduced chance of live birth compared with siblings. The likelihood of live birth after ART treatment in survivors was not affected by alkylator exposure (cyclophosphamide-equivalent dose, ≥8000 mg/m2 vs. none; RR, 1.04; 95% CI, 0.52-2.05). CONCLUSIONS: Childhood cancer survivors are as likely to undergo treatment using ART as sibling controls. The success of ART treatment was not reduced after alkylator exposure. The results from the current study provide needed guidance on the use of ART in this population.

Assessing the utility of the PC-PTSD-5 as a screening tool among a cancer survivor sample.

INTRODUCTION: Hematopoietic stem cell transplantation (HCT) is an intensive and invasive procedure used in cancer treatment that can lead to posttraumatic stress disorder (PTSD) symptoms. These symptoms are frequently overlooked in oncology and general health care settings. The suitability and utility of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) within the cancer population remains uncertain. This study aims to evaluate its performance as a brief (five-item) case-finding screening alternative to the longer (20-item) PTSD Checklist for DSM-5 (PCL-5) in survivors who received an HCT 1 to 5 years ago. METHODS: A total of 817 cancer survivors completed the PC-PTSD-5 and PCL-5 during recruitment for a randomized clinical trial. Optimal cut scores for identifying probable PTSD and item performance were determined using indices correcting for chance and item response theory analyses. RESULTS: Of the HCT sample, 10.4% screened as positive for probable DSM-5 PTSD using the PCL-5. The PC-PTSD-5 exhibited strong internal consistency and significant associations with PCL-5 scores (total, r = .82; items, rs = .56-.61). A cutoff score of 2 provided optimal sensitivity for screening (κ[Se] = .95), whereas a cut score of 4 demonstrated the highest efficiency for detecting a probable DSM-5 PTSD diagnosis on the PCL-5 (κ[Eff] = .39). Item response theory analyses indicated that item 4 (numbing) of the PC-PTSD-5 yielded the most informative data, with other items potentially lacking incremental utility. CONCLUSION: Although not an instrument validation study, these findings offer efficient evidence for using the PC-PTSD-5 as a succinct screening tool among cancer survivors in a clinical context.

Age at diagnosis and social risks among Black cancer survivors: Results from the Detroit Research on Cancer Survivors cohort.

BACKGROUND: Social risks are common among cancer survivors who have the fewest financial resources; however, little is known about how prevalence differs by age at diagnosis, despite younger survivors' relatively low incomes and wealth. METHODS: The authors used data from 3703 participants in the Detroit Research on Cancer Survivors (ROCS) cohort of Black cancer survivors. Participants self-reported several forms of social risks, including food insecurity, housing instability, utility shut-offs, not getting care because of cost or lack of transportation, and feeling unsafe in their home neighborhood. Modified Poisson models were used to estimate prevalence ratios and 95% confidence intervals (CIs) of social risks by age at diagnosis, controlling for demographic, socioeconomic, and cancer-related factors. RESULTS: Overall, 35% of participants reported at least one social risk, and 17% reported two or more risks. Social risk prevalence was highest among young adults aged 20-39 years (47%) followed by those aged 40-54 years (43%), 55-64 years (38%), and 65 years and older (24%; p for trend < .001). Compared with survivors who were aged 65 years and older at diagnosis, adjusted prevalence ratios for any social risk were 1.75 (95% CI, 1.42-2.16) for survivors aged 20-39 years, 1.76 (95% CI, 1.52-2.03) for survivors aged 40-54 years, and 1.41 (95% CI, 1.23-1.60) for survivors aged 55-64 years at diagnosis. Similar associations were observed for individual social risks and experiencing two or more risks. CONCLUSIONS: In this population of Black cancer survivors, social risks were inversely associated with age at diagnosis. Diagnosis in young adulthood and middle age should be considered a risk factor for social risks and should be prioritized in work to reduce the financial effects of cancer on financially vulnerable cancer survivors.

Long-term health outcomes by cancer diagnosed age among adolescent and young adult: multinational representative database.

BACKGROUND: The cancer experienced in adolescent and young adult (AYA) could disturb developmental changes and long-term life. The current AYA guidelines and research for survivorship were developed and reported according to the general age range of 15-39 years; however, expected life events vary by diagnosed age. We aimed to examine the social, psychological, and physical well-being of AYA cancer survivors by age at diagnosis using a multinational representative dataset focusing on age at diagnosis. METHODS: We conducted a cross-sectional study using the US and Korean National Health and Nutrition Examination Surveys from 2007 to 2018. Participants diagnosed with any cancer aged 15-39 years and were aged > 18 years at the survey year were defined as AYA cancer survivors. AYA were classified into three groups based on their diagnosed age: adolescent survivors (diagnosed between the ages of 15 and 19, n = 45), young adult survivors (diagnosed between the ages of 20 and 29, n = 238), and late young adult survivors (diagnosed between the ages of 30 and 39, n = 539). We also selected an age-, sex-, race-, and survey year-matched general population with 1:5 ratio among participants without cancer (N = 4110). RESULTS: The average age of the survey was 29.1, 43.7, and 48.7 years for AYA survivors diagnosed during adolescence, young adulthood, and late young adulthood, respectively. Adolescent survivors had more non-couple marital status (adjusted odds ratio (aOR), 1.34; 95% CI, 1.10-1.64) and unemployed (aOR, 1.30; 95% CI, 1.05-1.61) compared to late young adult survivors. Comparing with the matched general, adolescent survivors were more in poor general health (aOR, 4.65; 95% CI, 2.09-10.38) and unemployed (aOR, 2.17; 95% CI, 1.12-4.24) and late young adult survivors were more non-couple (aOR, 1.40; 95% CI, 1.05-1.86). CONCLUSION: This study provides evidence for future studies on long-term health, which may vary according to age at the time of diagnosis among AYA with cancer.

Accuracy of patient race and ethnicity data in a central cancer registry.

PURPOSE: Race and Hispanic ethnicity data can be challenging for central cancer registries to collect. We evaluated the accuracy of the race and Hispanic ethnicity variables collected by the Utah Cancer Registry compared to self-report. METHODS: Participants were 3,162 cancer survivors who completed questionnaires administered in 2015-2022 by the Utah Cancer Registry. Each survey included separate questions collecting race and Hispanic ethnicity, respectively. Registry-collected race and Hispanic ethnicity were compared to self-reported values for the same individuals. We calculated sensitivity and specificity for each race category and Hispanic ethnicity separately. RESULTS: Survey participants included 323 (10.2%) survivors identifying as Hispanic, a lower proportion Hispanic than the 12.1% in the registry Hispanic variable (sensitivity 88.2%, specificity 96.5%). For race, 43 participants (1.4%) self-identified as American Indian or Alaska Native (AIAN), 32 (1.0%) as Asian, 23 (0.7%) as Black or African American, 16 (0.5%) Pacific Islander (PI), and 2994 (94.7%) as White. The registry race variable classified a smaller proportion of survivors as members of each of these race groups except White. Sensitivity for classification of race as AIAN was 9.3%, Asian 40.6%, Black 60.9%, PI 25.0%, and specificity for each of these groups was > 99%. Sensitivity and specificity for White were 98.8% and 47.4%. CONCLUSION: Cancer registry race and Hispanic ethnicity data often did not match the individual's self-identification. Of particular concern is the high proportion of AIAN individuals whose race is misclassified. Continued attention should be directed to the accurate capture of race and ethnicity data by hospitals.

Association of metabolic health and obesity with coronary heart disease in adult cancer survivors.

BACKGROUND: The metabolically healthy obese (MHO) phenotype is associated with an increased risk of coronary heart disease (CHD) in the general population. However, association of metabolic health and obesity phenotypes with CHD risk in adult cancer survivors remains unclear. We aimed to investigate the associations between different metabolic health and obesity phenotypes with incident CHD in adult cancer survivors. METHODS: We used National Health Insurance Service (NHIS) to identify a cohort of 173,951 adult cancer survivors aged more than 20 years free of cardiovascular complications. Metabolically healthy nonobese (MHN), MHO, metabolically unhealthy nonobese (MUN), metabolically unhealthy obese (MUO) phenotypes were created using as at least three out of five metabolic health criteria along with obesity (body mass index ≥ 25.0 kg/m2). We used Cox proportional hazards model to assess CHD risk in each metabolic health and obesity phenotypes. RESULTS: During 1,376,050 person-years of follow-up, adult cancer survivors with MHO phenotype had a significantly higher risk of CHD (hazard ratio [HR] = 1.52; 95% confidence intervals [CI]: 1.41 to 1.65) as compared to those without obesity and metabolic abnormalities. MUN (HR = 1.81; 95% CI: 1.59 to 2.06) and MUO (HR = 1.92; 95% CI: 1.72 to 2.15) phenotypes were also associated with an increased risk of CHD among adult cancer survivors. CONCLUSIONS: Adult cancer survivors with MHO phenotype had a higher risk of CHD than those who are MHN. Metabolic health status and obesity were jointly associated with CHD risk in adult cancer survivors.

Effect of the 2024 Noto Peninsula earthquake on outpatient chemotherapy among cancer survivors in Japan: a retrospective study.

BACKGROUND: The study aim was to elucidate the effect of the 2024 Noto Peninsula earthquake on outpatient chemotherapy treatment of cancer survivors at Kanazawa Medical University Hospital (KMUH), Japan. METHODS: Medical and nursing records for January 4-31, 2024, from KMUH were retrospectively collected, and data for 286 participants were analyzed. RESULTS: Of the 286 participants, 95.1% were able to attend their first scheduled appointment. Of the 12 (4.2%) who could not attend because of the earthquake, 7 (58.3%) rescheduled their appointments. A total of 8 participants (2.8%) were unable to attend their second scheduled appointment in January, despite being able to attend their first appointment; 3 (37.5%) of these participants reported that they were unable to attend their appointments because of the effect of the earthquake. Chemotherapy was not administered to 53 (18.5%) participants who did attend, mainly owing to neutropenia, progressive disease, rash, and anemia. Evacuation information was available for 25 participants (8.7%); of these, 8 (28.6%) evacuated to their homes, 7 (25.0%) to public shelters, and 4 (14.3%) to apartments near the hospital. Disaster status information was obtained from 62 participants (21.7%), and indicated experiences such as home damage, water outages, and relying on transportation assistance from family to attend appointments. CONCLUSIONS: Most cancer survivors receiving chemotherapy at KMUH were able to maintain outpatient visits. However, a few could not attend because of the earthquake. Further studies are needed to provide more detailed information on the effect of disasters on cancer survivors and the potential factors underlying non-attendance at medical appointments.

Mixed-method approach to informing a lifestyle intervention to improve the survivorship of patients with endometrial cancer.

OBJECTIVES: To identify endometrial cancer survivors' (ECS) barriers and facilitators for participation in lifestyle interventions to improve their dietary and exercise behaviors. Our secondary objective is to determine baseline information: physical activity level, quality of life (QoL), and impact of COVID-19 on exercise, diet, and mental health. METHODS: Obese, early-stage ECS participated in 2-part mixed-methods data collection; Part 1: survey gathering sample characteristics, QoL, exercise, and basic endometrial cancer- related knowledge. Part 2: virtual focus group or individual interviews using a brainwriting premortem protocol. Statistical analysis was performed using SAS (version 8.3). Qualitative data were analyzed using deductive thematic coding guided by the RE-AIM framework. RESULTS: Twenty percent (70/358) of ECS from a survivorship database and clinic recruitment completed the survey; 16 ECS provided qualitative feedback. Common barriers to intervention participation included time and resource costs, meeting frequency, and pessimism about weight loss maintenance. Facilitators included an opportunity to connect with other survivors and a focus on health rather than weight loss. Most ECS could not identify exercise guidelines (60%) and 83% were not meeting these guidelines. Higher BMI was correlated with a lower confidence in completing in moderate physical activity (p-value = 0.0206). Post-COVID-19 pandemic, physical activity, nutritional decisions, and/or mental health worsened for 67% of ECS. CONCLUSION: ECS are a disparate population, with worsening behaviors and mental health following the pandemic. The identified ECS-specific barriers and facilitators to behavioral intervention participation are being used to simultaneously improve the reach of and adherence to a lifestyle intervention aimed at improving their health and QoL.

Pseudoephedrine for ejaculatory dysfunction after retroperitoneal lymph node dissection in testicular cancer.

OBJECTIVE: To assess the impact of ejaculatory dysfunction (EjD; failure of emission or retrograde ejaculation) on health-related quality of life (HRQoL) after retroperitoneal lymph node dissection (RPLND) for testicular cancer and explore the efficacy of pseudoephedrine hydrochloride as treatment. PATIENTS AND METHODS: In a single arm, phase II trial, patients at ≥6 months after RPLND were invited to complete patient-reported outcome measures (European Organisation for Research and Treatment of Cancer [EORTC] quality of life questionnaire [QLQ]-30-item core, EORTC QLQ-testicular cancer-26, and Brief Male Sexual Function Inventory) evaluating HRQoL and sexual function in follow-up (ACTRN12622000537752/12622000542796). If EjD was reported, post-ejaculatory urine ± semen analysis was undertaken. In eligible patients, pseudoephedrine hydrochloride 60 mg was administered orally every 6 h for six doses. The primary endpoint was sperm count >39 million sperm/ejaculate (>5th centile) following treatment. The trial was powered to detect a clinically relevant 36% achieving sperm count of >39 million sperm/ejaculate. Secondary endpoints included semen volume >1.5 mL, total motile sperm count, safety, and HRQoL impacts. RESULTS: Of the 58 patients enrolled, the median (interquartile range [IQR]) age was 35 (29-41) years, with a median (IQR) of 37 (18-60) months from RPLND. EjD was reported in 33 (57%), including 27/52 (52%) receiving follow-up at our centre. There were no differences in global HRQoL; however, role functioning (P = 0.045), sexual problems (P < 0.005), and sexual enjoyment (P = 0.005) was poorer if EjD was present. In all, 24/33 (73%) patients with EjD consented to pseudoephedrine treatment. Of 22 evaluable patients, four (18%) achieved a sperm count of >39 million/ejaculate (P = 0.20), and four (18%) had a semen volume of >1.5 mL (P = 0.20). There was a mean increase of 105 million sperm/ejaculate (P = 0.051) and 1.47 mL increase in semen volume (P = 0.01). No safety concerns arose. CONCLUSION: Ejaculatory dysfunction is common after RPLND but did not impact global HRQoL in our cohort. Pseudoephedrine improved EjD for some; however, its efficacy was lower than expected. Pseudoephedrine may be considered on an individualised basis.

Changes and predictors of social support in adolescent and young adult cancer survivors-Results of a 7-year longitudinal study.

OBJECTIVE: As social support has been shown to have beneficial effects on coping with cancer, our study aims to close the research gap on perceived social support in adolescent and young adult (AYA) cancer survivors. METHODS: AYAs evaluated their perceived positive social support (PS) and detrimental interactions (DI) by completing the Illness-Specific Social Support Scale (ISSS-8) upon completion of acute treatment (t1) as well as 1 year (t2) and 7 years (t6) later. Temporal changes of social support were examined. Sociodemographic, psychological and medical factors were investigated as predictors for PS and DI by using mixed effects models. RESULTS: We analyzed data from 319 cancer survivors (74.9% women). At baseline, survivors reported an average score of 13.73 (SD = 2.52) for PS and 3.92 (SD = 2.85) for DI. Average perceived PS changed over time, while DI remained stable. Males, AYAs without a partner and AYAs with clinically meaningful anxiety or depression levels reported fewer PS. Higher effort to cope with the disease and clinically significant anxiety and depression levels were associated with more perceived DI. CONCLUSIONS: Existing social networks and perceived social support should be evaluated regularly in AYA-cancer survivorship. The identification and discussion of mental health of AYAs should also be a standard component in survivor consultations both during treatment and follow-up care, as elevated depression and anxiety levels were associated with fewer PS and more perceived DI.

Combined association between dietary antioxidant quality score and leisure-time physical activity on sleep pattern in cancer survivors: a cross-sectional study of NHANES database.

This study aimed to explore the combined association between the dietary antioxidant quality score (DAQS) and leisure-time physical activity on sleep patterns in cancer survivors. Data of cancer survivors were extracted from the National Health and Nutrition Examination Surveys (NHANES) database in 2007-2014 in this cross-sectional study. Weighted multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association of DAQS and leisure-time physical activity on sleep patterns. The combined association was also assessed in subgroups of participants based on age, and use of painkillers and antidepressants. Among the eligible participants, 1,133 had unhealthy sleep patterns. After adjusting for covariates, compared to low DAQS level combined with leisure-time physical activity level <600 MET·min/week, high DAQS level combined with leisure-time physical activity ≥600 MET·min/week was associated with lower odds of unhealthy sleep patterns (OR=0.41, 95%CI: 0.23-0.72). Additionally, the association of high DAQS level combined with high leisure-time physical activity with low odds of unhealthy sleep patterns was also significant in <65 years old (OR=0.30, 95%CI: 0.13-0.70), non-painkiller (OR=0.39, 95%CI: 0.22-0.71), non-antidepressant (OR=0.49, 95%CI: 0.26-0.91) and antidepressant (OR=0.11, 95%CI: 0.02-0.50) subgroups. DAQS and leisure-time physical activity had a combined association on sleep patterns in cancer survivors. However, the causal associations of dietary nutrient intake and physical activity with sleep patterns in cancer survivors needs further clarification.

Feasibility of telehealth exercise and nicotinamide riboside supplementation in survivors of childhood cancer at risk for diabetes: A pilot randomized controlled trial.

BACKGROUND: Childhood cancer survivors (CCS) have a 50% higher risk of diabetes mellitus (DM) compared with the general population. Interventions in survivors with prediabetes (fasting glucose 100-125 mg/dL or hemoglobin A1c 5.7%-6.4%) may mitigate the development of DM and its attendant morbidity, but there is limited information on the feasibility of secondary prevention in this setting. METHODS: This 6-week pilot feasibility 1:1 randomized controlled trial enrolled 20 CCS on a structured telehealth exercise program ± nicotinamide riboside (NR), a nicotinamide adenine dinucleotide precursor. Feasibility metrics were: (1) ≥50% of eligible CCS enrolled onto study; (2) ≥70% of participants completed baseline and end-of-study assessments; (3) ≥70% compliance with exercise and NR. Secondary endpoints included changes in biomarkers associated with glucose homeostasis and muscle health. RESULTS: Median age (years) at cancer diagnosis was 16.5 (range, 1.5-21.5) and 35.5 (range, 18.0-67.0) at study enrollment. Enrollment rate was 87%, and 85% of participants completed baseline and end-of-study assessments. The mean percentage of exercise sessions completed was 86.6%; NR compliance was > 90%. There were no severe adverse events attributable to study interventions. Secondary endpoints were not significantly different between study arms at study completion. Myostatin decrease was observed in participants who completed a higher median number of exercise sessions and was associated with decreased intramuscular adipose tissue and increased lower extremity muscle cross-sectional area. CONCLUSIONS: A telehealth exercise intervention ± NR supplementation was feasible in CCS with prediabetes. Future studies in larger cohorts may be needed to evaluate their beneficial effects on muscle health and DM risk among CCS.

Social participation of school-aged survivors of pediatric brain tumors: A daily diary report.

BACKGROUND: Difficulties with social functioning are common among survivors of pediatric brain tumors. Social participation is an understudied measure of social functioning that is associated with emotional health across the lifespan. This paper uses a diary method to assess the social participation of survivors of pediatric brain tumors in middle childhood. PROCEDURE: Survivors of pediatric brain tumors (N = 47; age 10.6 ± 1.4 years; 51.1% male, 89.4% White) who were 5.3 (SD = 2.4, range: 2-9.9) years post therapy completed a daily diary assessment of social interaction (5-7 days) and an objective measure of facial affect recognition. The participant's caregiver completed the NIH Toolbox Emotion Measures and a background information questionnaire. RESULTS: Overall, frequency and quality of reported social interactions were low for survivors, with a large subset of survivors (n = 16, 34%) endorsing fewer than 10 social interactions over the course of a typical school week, and almost half of parents (48.9%) reporting that their child participates in zero social activities outside of school during a typical week. Participants engaged in more positive social participation exhibited stronger social skills (facial affect recognition (F(2,44)  = 4.85, p < .05). CONCLUSIONS: School-aged survivors of pediatric brain tumors seemed to be infrequently engaged in social participation and quality interaction with peers. More specifically, the interactions most commonly reported on the diary assessment are not indicative of friendship development and maintenance. Survivors of pediatric brain tumors would likely benefit from interventions designed to increase quality time spent with peers.
