Cutaneous melanoma in adolescents and young adults.

Cutaneous malignant melanoma (CMM) ranks among the five most common cancers in young people in high-income countries and it features peculiar clinicopathological traits. Very few studies have addressed the quality of care and the costs for adolescents and young adults (AYA) population. To provide a comprehensive epidemiological and clinicopathological profile of CMM in AYA. The study also addresses the cost-of-illness and the diagnostic-therapeutic performance indicators by patient age category. This population-based cohort study included 2435 incident CMM (age range 15-65 years; age 15-39 = 394; age 40-65 = 2041), as recorded in 2015, 2017 and 2019 by the Regional Veneto Cancer Registry (Italy). Cramer's-V tested the strength of association between pairs of variables. The Kaplan-Meier method was used to test the association between age and survival rate. The clinical performance indicators were computed using the Clopper-Pearson exact method. In AYA patients (16.2%), CMM incidence rates increased significantly from 1990 to 2019. Low-stage CMM (p = 0.007), radial growth pattern (p = 0.026) and lower Clark levels (p = 0.007) prevailed; males had less advanced malignancies (p = 0.003), with the trunk as the most common primary site (67.5%); the lower limbs (32.6%) were the most common primary site for females (p < 0.001). Overall survival was better in AYA than adults. No significant difference was detected in the clinical management of the two age groups, with the only exception of the margin in wide local excision. The care costs were lower in AYA (€195.99 vs. €258.94, p = 0.004). In AYA patients, the CMM clinicopathological presentation shows a distinctive profile. The present results provide critical information for optimizing primary and secondary prevention strategies and for tailoring diagnostic therapeutic procedures to the peculiar profile of AYA CMM patients.

Abstract PO5-10-07: Risk factors associated with secondary cancers in AYA patients with breast cancer. A SEER database study

Abstract Background Adolescents and young adults (AYA) diagnosed with breast cancer face unique challenges and have distinct characteristics compared to older patients. While primary breast cancer remains a significant concern, the risk of developing secondary cancers in this population is also of great importance. This study aimed to identify these risk factors by analyzing a large cohort of AYA breast cancer patients using SEER (Surveillance Epidemiology and End Result) Database. Methods Patients were identified from SEER Research Data 17, from 2000 to 2019. Patients aged 18-39 years with breast cancer and at least 1 year of survival were identified. Secondary cancers were then identified and included any disease site. Patient demographic and clinical characteristics were summarized by secondary cancer status using Mann-Whitney U and Fisher’s exact tests. Overall survival from the initial breast cancer diagnosis was summarized by secondary cancer status using standard Kaplan-Meier methods, where the median and 3/5-year rates were estimated with 95% confidence intervals. Comparisons were made using the log-rank test. SAS v9.4 (Cary, NC) was used at a significance level of 0.05. Results A total of 47,912 AYA breast cancer patients were identified, of which 2,886 (6.0%) developed a secondary cancer at least 1 year after the initial breast cancer diagnosis. When comparing patients with and without secondary cancers, we observed significant differences with respect to age at initial breast cancer diagnosis, race, stage, nodal status, surgical procedure, ER status, PR status, Her2 status, and sub-type (Table 1). The analysis of overall survival showed that, from the time of breast cancer diagnosis, there was no statistically significant difference between patients with and without secondary cancers. However, this may be due to an immortal time bias. Breast was the most common site of secondary cancer (67%) followed by gynecological (7%), colorectal (3.7%), skin (3.4%) lung and hematologic (2.7%) Compared to other subtypes, TNBC patients were found to have much shorter time to secondary cancer development of 38 months compared to Her2+ and ER/PR+ (40 and 45 months respectively, P&amp;lt; 0.001). Black and Hispanic individuals were found to have higher rates (7.4% and 6.3%) and earlier development of secondary cancer (76 months and 74 months) as compared to whites and Asians (5.9% and 5%, 88 months and 81 months, P&amp;lt; 0.001 and P&amp;lt; 0.002 respectively). Conclusion This study identified several risk factors associated with the development of secondary cancers in AYA breast cancer patients such as age at initial breast cancer diagnosis, race, stage, nodal status, surgical procedure and sub-type. Higher rates and early development of secondary cancer were observed among TNBC subtype and Black and Hispanic races that calls for further investigation and tailored interventions to improve outcomes in specific patient populations.

Abstract PO4-17-10: Epidemiological Analysis and Overall Survival of Female Adolescent and Young Adults Breast Cancer in a Developing Middle Eastern Country Over 18 Years

Abstract Background: Breast cancer is the most common type of cancer among female adolescents and young adults (AYAs) aged 15-39 years at diagnosis. AYAs with breast cancer have worse prognosis and are more likely to present with unfavorable tumor biology. However, breast cancer in AYAs is still poorly reported in middle eastern populations. Methodology: This is a retrospective cohort study which examined female AYAs patients aged 15 to 39 years at the time of diagnosis who were diagnosed with breast cancer between 2000 and 2018, using data from the Jordan Cancer Registry. Kaplan-Meier analysis was performed to assess the 5-year overall survival of the patients over time. Results: A total of 3831 Female AYAs were diagnosed with breast cancer in Jordan between 2000 and 2018 with a median age of 34.2 (IQR 30.9-38.3) years. 43.2% of female AYAs breast cancer cases were right breast cancer, whereas left breast cancer occurred in 47.4% of cases, and only 2.15% of cases were bilateral breast cancer. Meanwhile, 7.31% of cases did not have a reported laterality in the registry records. Most female AYAs patients had high grade breast cancer with grade III breast cancer being the most common (N=1349, 35.2%) followed by grade II breast cancer (N=1093, 28.5%). Among this female AYA cohort, 2208 (59.3%) were treated with surgical intervention, 1621 (43.5%) patients were given chemotherapy, 1220 (32.7%) patients had radiotherapy, 265 (7.15%) patients had hormonal therapy and only 47 (1.27%) were treated with immunotherapy. Among the entire studied cohort, 229 (5.98%) patients died during follow up period. The 5-year overall survival was 94% (95% CI 93.3% to 94.8%) Conclusion: Female AYAs breast cancer tends to have a predilection towards the left breast, but presents at a more advanced grade compared with other age groups in females.

Fulfilling the Role of a Parent While Undergoing Treatment for Cancer: A Review of the Literature and the Potential Impact of Childcare Support on Cancer Outcomes.

Breast cancer is the most prevalent malignancy among adolescents and young adults (AYAs). Despite the efficacy of chemotherapy, AYA patients contend with psychosocial challenges, including psychological distress and financial toxicity, exacerbated further by those with dependent children. Parenting responsibilities intersect with cancer care, impacting both family dynamics and treatment adherence. Despite recognized needs, however, the impact of parenting concerns or even parenting status and the presence of dependents has not been systematically addressed and there is a paucity of interventional research regarding patients with cancer as concomitant caregivers. A feasibility study conducted by the Brown University Oncology Cooperative Group demonstrated the potential benefits of providing financial assistance for childcare, both improving treatment adherence and reducing distress among participants. Similar interventions have shown promise in addressing financial hardships for AYA patients with cancer who are concomitant caregivers. Ultimately, parenting concerns have a significant impact on medical decision-making, and further interventional research on childcare support is required to examine the ways in which health systems can improve family stability, stress, and quality of life.

Global burden of rheumatoid arthritis among adolescents and young adults aged 10-24 years: A trend analysis study from 1990 to 2019.

In recent decades, there has been a global increase in the burden of rheumatoid arthritis (RA) among adolescents and young adults (AYAs), making it a significant public health issue. However, our understanding of the disease burden, harm, and influencing factors of RA in this population remains insufficient. This study aimed to assess the trends in RA burden among AYAs aged 10-24 years from 1990 to 2019 at the global, regional, and national levels. Incidence, prevalence, and disability-adjusted life years (DALYs) rate per 100,000 population, as well as average annual percentage changes (AAPCs), of RA among individuals aged 10-24 years were reported globally, regionally, and nationally based on the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019). These global trends were further analyzed by age, sex, and Sociodemographic index (SDI). Joinpoint regression analysis was used to determine the year in which the most significant changes in global trends occurred. Globally, the incidence of RA among AYAs increased from 4.98 per 100,000 population in 1990 to 5.41 per 100,000 population in 2019, with an AAPCs of 0.29 (95%CI: 0.26, 0.32, p < 0.001). The most significant increase occurred in 2000, while the most significant decrease occurred in 2014. The prevalence increased from 34.11 per 100,000 population in 1990 to 36.34 per 100,000 population in 2019, with an AAPCs of 0.22 (95%CI: 0.19, 0.24, p<0.001); The most significant increase was observed in 2000, and the most significant decrease occurred in 2014. DALYs rate with RA were 5.96 per 100,000 population in 1990 and 5.79 per 100,000 population in 2019 for AYAs, with an average decrease of 0.1 years per year (AAPCs = -0.1, 95%CI: -0.2, -0.01, p = 0.04). In terms of gender, the incidence, prevalence, and DALYs rate were higher for females compared to males during the same period. Regarding age, the incidence, prevalence, and DALYs rate increased with increasing age. Based on the SDI quintile, the incidence, prevalence, and DALYs rate of RA were highest in countries with high SDI and lowest in countries with low SDI from 1990 to 2019. However, the relationship between incidence and SDI is non-linear. In terms of regions, Tropical Latin America exhibited the highest incidence, prevalence, and DALYs rate, while Andean Latin America experienced the most rapid increase in incidence and prevalence. Southern Latin America saw the fastest growth in DALYs rate, whereas Southern Sub-Saharan Africa witnessed the most significant decline. In conclusion, the study revealed an overall increase in the incidence and prevalence of RA among adolescents and young adults (AYAs) over the past three decades, while DALYs rate remained relatively stable. Furthermore, the incidence, prevalence, and DALYs rate of RA were found to increase with age. Fortunately, recent proactive preventive measures and treatment methods have shown promising results. Moving forward, it is crucial to prioritize the female population and AYAs patients in order to further alleviate the global burden of RA.

Factors affecting the long-term prognosis of patients in the AYA generation with epithelial ovarian cancer: A multicenter propensity score matching analysis.

Ovarian carcinoma (OvCa) is more common in the elderly, but also affects the adolescent and young adult (AYA) generation, which refers to those aged 15-39 years. Although the characteristics of OvCa may differ between AYAs and non-AYAs, limited information is currently available on differences in prognostic factors. Therefore, we herein investigated prognostic factors for and the prognosis of OvCa in AYAs. We also examined the prognostic impact of fertility-sparing surgery in a subgroup analysis. We retrospectively collected data on 4897 patients with OvCa from the databases of multiple institutions and ultimately included 1161 patients with epithelial ovarian cancer (EOC). We performed a survival analysis to compare AYAs and non-AYAs with backgrounds that conformed to those of AYAs using the propensity score (PS) matching method. A Cox regression analysis was also conducted to evaluate each predictor of recurrence-free survival (RFS) and overall survival (OS) in the original population. As a subgroup analysis, a multivariate analysis stratified by the AYA and non-AYA generations was performed. In total, 119 AYA patients were included in this study. After PS adjustments, no significant differences were observed in RFS or OS between AYAs and non-AYAs. Prognostic factors differed between AYAs and non-AYAs, particularly in histology and cytology. A multivariate analysis stratified by the AYA and non-AYA generations described that uterine-preserving surgery (UPS) did not have a significant impact on the prognosis of AYAs or non-AYAs. In cases with recurrence, no significant differences were observed in RFS and recurrent sites in the two groups. Characteristic prognostic factors for EOC in AYAs were identified. The present results indicate the limited prognostic impact of UPS for EOC in AYAs.

Stroma-infiltrating T cell spatiotypes define immunotherapy outcomes in adolescent and young adult patients with melanoma

The biological underpinnings of therapeutic resistance to immune checkpoint inhibitors (ICI) in adolescent and young adult (AYA) melanoma patients are incompletely understood. Here, we characterize the immunogenomic profile and spatial architecture of the tumor microenvironment (TME) in AYA (aged ≤ 30 years) and older adult (aged 31–84 years) patients with melanoma, to determine the AYA-specific features associated with ICI treatment outcomes. We identify two ICI-resistant spatiotypes in AYA patients with melanoma showing stroma-infiltrating lymphocytes (SILs) that are distinct from the adult TME. The SILhigh subtype was enriched in regulatory T cells in the peritumoral space and showed upregulated expression of immune checkpoint molecules, while the SILlow subtype showed a lack of immune activation. We establish a young immunosuppressive melanoma score that can predict ICI responsiveness in AYA patients and propose personalized therapeutic strategies for the ICI-resistant subgroups. These findings highlight the distinct immunogenomic profile of AYA patients, and individualized TME features in ICI-resistant AYA melanoma that require patient-specific treatment strategies.

Alternatives to dental opioid prescribing after tooth extraction (ADOPT): protocol for a stepped wedge cluster randomized trial

BackgroundDentists and oral surgeons are leading prescribers of opioids to adolescents and young adults (AYA), who are at high risk for developing problematic opioid use after an initial exposure. Most opioids are prescribed after tooth extraction, but non-opioid analgesics provide similar analgesia and are recommended by multiple professional organizations.MethodsThis multi-site stepped wedge cluster-randomized trial will assess whether a multicomponent behavioral intervention can influence opioid prescribing behavior among dentists and oral surgeons compared to usual practice. Across up to 12 clinical practices (clusters), up to 33 dentists/oral surgeons (provider participants) who perform tooth extractions for individuals 12–25 years old will be enrolled. After enrollment, all provider participants will receive the intervention at a time based on the sequence to which their cluster is randomized. The intervention consists of prescriber education via academic detailing plus provision of standardized patient post-extraction instructions and blister packs of acetaminophen and ibuprofen. Provider participants will dispense the blister packs and distribute the patient instructions at their discretion to AYA undergoing tooth extraction, with or without additional analgesics. The primary outcome is a binary, patient-level indicator of electronic post-extraction opioid prescription. Data for the primary outcome will be collected from the provider participant’s electronic health records quarterly throughout the study. Provider participants will complete a survey before and approximately 3 months after transitioning into the intervention condition to assess implementation outcomes. AYA patients undergoing tooth extraction will be offered a survey to assess pain control and satisfaction with pain management in the week after their extraction. Primary analyses will use generalized estimating equations to compare the binary patient-level indicator of being prescribed a post-extraction opioid in the intervention condition compared to usual practice. Secondary analyses will assess provider participants’ perceptions of feasibility and appropriateness of the intervention, and patient-reported pain control and satisfaction with pain management. Analyses will adjust for patient-level factors (e.g., sex, number of teeth extracted, etc.).DiscussionThis real-world study will address an important need, providing information on the effectiveness of a multicomponent intervention at modifying dental prescribing behavior and reducing opioid prescriptions to AYA.ClinicalTrials.govNCT06275191.

A Scoping Review of Oncosexology Policy and Practice Tools Focused on Adolescents and Young Adults.

Background: Despite being considered a key component of quality-of-life, sexual health concerns in adolescents and young adults (AYA) patients with cancer (aged 15-39 years old) are often unmet due to barriers from both patients and health care professionals (HCPs). Investigation into policy and practice tools in this scope of practice is also limited. Aim: To review the literature on policy and practice tools in AYA oncosexology. Method: A scoping review was conducted using four databases: Medline, EMCARE, EMBASE, and PsycINFO, based on the Joanna Briggs Institute Scoping Review methodology. Retrieved articles were extracted into Covidence, followed by two screening rounds. Descriptive and basic content analyses were performed for evidence synthesis. Results: Seventy-four articles were included after screening rounds and citation searches. Overall, oncosexology policy and practice tools were categorized into screening tools (11 articles), guidelines (38 articles), training programs (15 articles), service delivery initiatives (5 articles), and the evaluation of their feasibility/challenges to implementation (5 articles). Among these, only ten articles were specifically about the AYA population. They helped identify and resolve sexual health concerns in AYA patients with cancer by providing strategies to overcome communication barriers, treatment options, and information resources for patients, and by advocating for more HCP education on this topic. Conclusion: The results warrant the need for more research, implementation and expansion of policy and practice tools for sexual health issues in AYA patients with cancer.

Venetoclax Combination Treatment of Acute Myeloid Leukemia in Adolescents and Young Adult Patients.

Over the past two decades, the prognosis in adolescents and young adults (AYAs) diagnosed with acute myeloid leukemia (AML) has significantly improved. The standard intensive cytotoxic treatment approach for AYAs with AML, consisting of induction chemotherapy with anthracycline/cytarabine combination followed by consolidation chemotherapy or stem cell transplantation, has lately been shifting toward novel targeted therapies, mostly in the fields of clinical trials. One of the most recent advances in treating AML is the combination of the B-cell lymphoma 2 (Bcl-2) inhibitor venetoclax with hypomethylating agents, which has been studied in elderly populations and was approved by the Food and Drug Administration (FDA) for patients over 75 years of age or patients excluded from intensive chemotherapy induction schemas due to comorbidities. Regarding the AYA population, venetoclax combination therapy could be a therapeutic option for patients with refractory/relapsed (R/R) AML, although data from real-world studies are currently limited. Venetoclax is frequently used by AYAs diagnosed with advanced hematologic malignancies, mainly acute lymphoblastic leukemia and myelodysplastic syndromes, as a salvage therapeutic option with considerable efficacy and safety. Herein, we aim to summarize the evidence obtained from clinical trials and observational studies on venetoclax use in AYAs with AML. Based on the available evidence, venetoclax is a safe and effective therapeutic option for R/R AML AYA patients. However, further research in larger cohorts is needed to confirm these data, establishing the benefits of a venetoclax-based regimen for this special population.

Outcomes and Long-Term Survival of Adolescent and Young Adult Patients Admitted to the Intensive Care Unit Following Allogeneic Hematopoietic Stem Cell Transplantation: A Single-Center Experience of 152 Patients.

Prognostic factors reliably predicting outcomes for critically ill adolescent and young adult (AYA) patients undergoing allogeneic hematopoietic cell transplantation (allo-HSCT) are lacking. We assessed transplant and intensive care unit (ICU)-related factors impacting patient outcomes. AYA patients who underwent allo-HSCT and required ICU admission at a Tertiary care Centre, during the period of 2003-2013, were included in this retrospective review. This was a non-interventional study. Only outcomes after the first allo-HSCT and index ICU admissions were analyzed. Disease-, transplant-, and ICU-related variables were analyzed to identify risk factors predictive of survival. Overall, 152 patients were included (males, 60.5%); median age at transplantation was 24 years (interquartile range [IQR] 18-32.5); median age at admission to the ICU was 25.8 years (IQR 19-34). Eighty-four percent underwent transplantation for a hematological malignancy; 129 (85%) received myeloablative conditioning. Seventy-one percent of ICU admissions occurred within the first year after allo-HSCT. ICU admission was primarily due to respiratory failure (47.3%) and sepsis (43.4%). One hundred and three patients (68%) died within 28 days of ICU admission. The 1- and 5-year overall survival rates were 19% and 17%, respectively. Main causes for ICU-related death were refractory septic shock with multiorgan failure (n = 49, 32%) and acute respiratory distress syndrome (ARDS) (n = 39, 26%). Univariate analysis showed that ICU mortality was associated with an Acute Physiology and Chronic Health Evaluation (APACHE) II score >20, a sequential organ failure assessment (SOFA score) > 12, a high lactate level, anemia, thrombocytopenia, leukopenia, hyperbilirubinemia, a high international normalized ratio (INR) and acute graft-versus-host disease (GVHD). Multivariate analysis identified thrombocytopenia, high INR, and acute GVHD as independent predictors of mortality. In AYA allo-HSCT patients admitted to the ICU, mortality remains high. Higher SOFA and APACHE scores, the need for organ support, thrombocytopenia, coagulopathy, and acute GVHD predict poor outcomes.

Transitioning from Pediatric- to Adult-focused Dialysis Care: A Systematic Review with Recommendations

Background: There is limited data evaluating the practices of nephrologists who prepare dialysis-dependent adolescents and young adults (AYA) for healthcare transition (HCT) from pediatric- to adult-focused healthcare. The aims of this manuscript are to 1) critically evaluate the current evidence and experiences surrounding HCT from pediatric- to adult-focused dialysis units and 2) make recommendations that can be implemented for this process. Methods: We searched PubMed, EMBASE, CINAHL, COCHRANE, and clinicaltrials.gov to identify studies that pertain to the HCT of AYA patients from pediatric- to adult-focused dialysis care. Results: A total of 14 studies were included and were grouped into subcategories to facilitate data synthesis: HCT process, preparedness of patient and family, preparedness of adult-focused nephrology providers, barriers to HCT, and quality of life. These included studies highlight the importance of creating an HCT process with a formal policy. They focus on the importance of patient and family preparedness and on measuring HCT readiness using standardized scales. They also underline the importance of identifying adult-focused nephrology ‘HCT champions’ to care for AYA requiring dialysis. Lastly, they emphasize the importance of measuring the quality of life in AYA patients to ensure optimal patient-centered HCT. Conclusion: There is limited data on HCT for AYA with ESKD. Upon review and analysis of current literature, we recommend: creating a formal, written HCT policy; setting achievable goals for health self-management and conducting regular assessments of HCT readiness; identifying a lead or ‘champion’ at an accepting adult-focused dialysis unit and ensuring good communication between pediatric and adult providers; and completing annual quality-of-life assessments.

Abstract 3955: A proteogenomic study of high-grade glioma among adolescents and young adults

Abstract To unravel the molecular mechanisms underlying high-grade glioma (HGG) in adolescent and young adult (AYA) patients, we conducted a comprehensive proteogenomic analysis for 34 AYA (age 15-40) and 59 pediatric (age 0-15) HGG cases. Our approach involved whole genome sequencing, methylation profiling, RNA sequencing, and a suite of mass spectrometry-based proteomic experiments, including global proteomic, phosphoproteomic, and glycoproteomic profiling. The proteomics study successfully identified and quantified approximately 11,000 proteins, 33,000 phosphosites, and 3000 glycopeptides with a 50% missing filtering threshold. To identify the unique characteristics of AYA HGG in contrast to both pediatric and adult HGG, we further integrated a proteogenomic dataset of 99 adult GBM tumors previously published by CPTAC and collaborators (PMID: 33577785). Our study unveiled a collection of mutations, copy number variations, epigenetic modifications and gene fusions that exhibited different frequencies across tumors from pediatric, AYA, and adult patients. Moreover, the influence of these genetic variations on RNA/protein activities also varied across different age groups. Clustering analysis using age-dependent molecular profiles revealed striking differences in RNA/protein/phosphosite activities between patients aged 15-26 and 26-40. Additionally, significantly better overall survival (OS) was observed in the 26-40 age group compared to all other age groups, highlighting distinct biological characteristics within the AYA category that differentiate adolescents from young adults.By leveraging proteogenomic datasets from normal brain tissues (PMID: 30518843), we identified genes, proteins, and pathways with differential age-dependent molecular profiles between tumor and normal brain tissues. Notably, this analysis highlighted significant alterations in proteins from the oxidative phosphorylation, tricarboxylic acid (TCA) cycle, and myelin sheath pathways in tumors compared to normal tissues, some of which were found to be sex-specific.To search for prognostic markers, we introduced a novel approach called Trans-Population Survival Analysis through Interpolation of Age-Dependent Tumor Molecular Profiles. Applying this method on the kinase activity scores derived from the phosphoproteomic data, we identified 150 kinases whose activities were significantly associated with OS among AYA patients. Additionally, employing a causal network analysis tool, we pinpointed six kinases causally linked to OS, suggesting their potential as treatment targets. This study not only characterizes the molecular landscape of AYA HGG but also explores the disease trajectory across the lifespan. Our findings shed light on the intricate interplay of various factors influencing glioma etiology and patient outcomes, paving the way for a deeper understanding of HGG in the AYA population.

Association between different regional lymph node metastases of papillary thyroid carcinoma in adolescents and young adults.

Adolescents and young adults (AYA) describe the demographic aged between 15-39 years diagnosed with cancer. This group is particularly at risk of papillary thyroid carcinoma (PTC) with a greater severity compared with other ages. Through comparative design, the present study aimed to quantify central lymph node metastasis (CLNM) risk in AYAs. A total of 463 AYA patients with PTC and 489 patients >39 years old with PTC from Ningbo Medical Center Lihuili Hospital (Ningbo, China) were enrolled. Details such as demographic data, serum indices and fine-needle aspiration from the Electronic Medical Records System were extracted and analyzed. AYA patients had significantly higher rates of ipsilateral Hashimoto thyroiditis, thyroid capsular invasion (TCI), CLNM, larger tumors and more positive central lymph nodes (CLN). Independent risk factors of CLNM in AYA patients were as follows: Male sex, presence of TCI, multifocality, bilateral disease and maximum tumor diameter (MTD) ≥1.0 cm. Independent risk factors of lateral lymph node metastasis in AYAs with CLNM were as follows: MTD ≥1.0 cm, maximum diameter of positive CLN ≥1.0 cm, and presence of ipsilateral nodular goiter. Furthermore, AYA patients with PTC displayed significantly greater aggression in primary tumor invasion and neck lymph node metastasis. Based on these findings, a treatment stratification chart was created to guide the PTC treatment approach for AYAs. The present study is registered at the Chinese Clinical Trials Registry (trial registration no. ChiCTR2200064921) in November 2022.

Epidemiology and risk factors of bloodstream infections among adolescents and young adults with acute lymphoblastic leukaemia: An 11-year retrospective cohort study.

Adolescent and young adults (AYAs) belong to a unique category of patients diagnosed with acute lymphoblastic leukaemia (ALL). Bloodstream infection (BSI) is a leading cause of treatment-related mortality in ALL patients. However, the epidemiology and risk factors for mortality from BSIs in AYA patients remain unclear. In this study, we analysed these aspects in AYAs patients and compared similarities and differences with children (<15 years old) and older adults (>39 years old). We analysed the pathogenic epidemiology, antibiotic resistance and BSI risk factors of 73 children, 180 AYAs, and 110 older adults with ALL in three comprehensive hospitals from January 2010 to August 2021. The data on BSIs in AYAs were compared to that of the other two groups. In this study, the epidemiology of BSIs in AYAs was similar to that of older adult patients. Concerning clinical characteristics, most AYAs and older adults with BSIs were in a relapsed or uncontrolled state (34.5% vs. 35.4%, p = 0.861). In terms of pathogen distribution, Gram-negative bacteria (GNB) were the most common causative pathogens in AYAs and older adult groups. Extended-spectrum beta-lactamase (ESBL)-producing bacteria were more commonly found in AYAs than in children (32.8% vs. 16.4%, p = 0.09). Regarding risk factors, the length of hospitalization (>14 days) and renal inadequacy (creatinine ≥ 177 μmol/L) were influencing factors for 30-day mortality in AYAs patients with BSIs. In our study, AYA patients with BSIs showed clinical characteristics and pathogen distributions similar to those of older adult patients but quite different from those of children.

Kidney adolescent and young adult clinic: A transition model in Africa.

Adolescents and Young Adults (AYAs) with chronic kidney disease (CKD) have challenges unique to this developmental period, with increased rates of high-risk behavior and non-adherence to therapy which may impact the progression of kidney disease and their requirement for kidney replacement therapy (KRT). Successful transition of AYA patients are particularly important in low- and middle-income countries (LMICs) where KRT is limited, rationed or not available. Kidney AYA transition clinics have the potential to improve clinical outcomes but there is a paucity of data on the clinical translational impact of these clinics in Africa. This review is a reflection of the 20-year growth and development of the first South African kidney AYA transition clinic. We describe a model of care for patients with CKD, irrespective of etiology, aged 10-25 years, transitioning from pediatric to adult nephrology services. This unique service was established in 2002 and re-designed in 2015. This multidisciplinary integrated transition model has improved patient outcomes, created peer support groups and formed a training platform for future pediatric and adult nephrologists. In addition, an Adolescent Centre of Excellence has been created to compliment the kidney AYA transition model of care. The development of this transition pathway challenges and solutions are explored in this article. This is the first kidney AYA transition clinic in Africa. The scope of this service has expanded over the last two decades. With limited resources in LMICs, such as KRT, the structured transition of AYAs with kidney disease is not only possible but essential. It is imperative to preserve residual kidney function, maximize the kidney allograft lifespan and improve adherence, to enable young individuals an opportunity to lead productive lives.

Employment outcomes of adolescent and young adult (AYA) cancer survivors and their partners: A Dutch population-based study.

The aim of this population-based registry study was to examine the impact of cancer on employment outcomes in adolescent and young adult (AYA) survivors and their partners and associated sociodemographic and clinical characteristics. A total of 2456 AYA cancer patients, diagnosed in 2013 and aged 18 through 39years old, were selected from the Netherlands Cancer Registry and linked to employment data from Statistics Netherlands, from which 1252 partners of AYAs could be identified. For both patients and their partners, a control group with same age, migration background, and sex was selected. The impact (i.e., causal effect) was estimated by implementing a doubly robust difference-in-differences method, from 3years before to 5years after cancer diagnosis. Patients suffered a reduced employment probability (3.8 percentage points) and number of hours worked when employed (3.8%). This effect was larger for females, and individuals with a migration background, high tumor stage, or diagnosed with a central nervous system tumor/hematologic malignancy. In regard to employment, no significant effect could be found for the patients' partners, although a 5.5 percentage-point increase in employment probability was found in partners who were either unemployed or worked fewer than 400hours. A cancer diagnosis significantly affects employment outcomes of AYA patients with cancer. Patients at risk should have access to services such as job counseling to help them return into society in the best possible way. No objective impact on partners' employment outcomes was found; however, subjective well-being was not taken into account. This study estimated the causal effect of a cancer diagnosis on employment outcomes. Adolescent and young adult cancer survivors face a reduction in both employment probability and the number of hours worked when employed. Partners that were unemployed or worked the least number of hours a year before diagnosis had a 5.5 percentage-point increased employment probability, but for other partners effects are small.

DEVELOPING A SCORING SYSTEM TO PREDICT CHRONIC OPIOID USE AMONG ADOLESCENTS AND YOUNG ADULTS WITH INFLAMMATORY BOWEL DISEASE

Abstract BACKGROUND Chronic, or long-term, opioid use is associated with higher risk of addiction and death as well as poor inflammatory bowel disease (IBD) outcomes. Recent data estimate that up to 20% of adolescents and young adults (AYA) with IBD may be chronic opioid users. Models to predict chronic opioid use among AYA with IBD may support identification, clinical management, and follow-up of patients at high risk of opioid dependence. We aimed to develop a clinical predictive model based on administrative data for chronic opioid use among AYA with IBD. METHODS We performed a retrospective analysis of AYA patients between 15-29 years treated at a tertiary academic center for IBD management from 3/2018-12/2021. Univariate regression was performed to identify individual predictors of chronic opioid use. Multivariate regression was performed using variables with p-values &amp;lt;0.15 in univariate regression. Variables significant after adjustment were included in a simple scoring system. Point estimates for chronic opioid use risk probabilities were derived using the percentage of chronic opioid users in our analytic cohort assigned that prognostic score. 95% confidence intervals were estimated using a bootstrapping technique with 1000 replications. RESULTS Our final cohort included 575 unique AYA patients with IBD. Patients were, on average, 23 years old (IQR 20-26) and 69% of the cohort was female. 41% had a diagnosis of Crohn’s disease, 25% with ulcerative colitis and 64% with indeterminate colitis. Patients’ mean age at index IBD diagnosis was approximately 22 years and over half (56%) had undergone prior IBD surgery. Following adjustment, eleven factors were associated with the highest odds of chronic opioid use, including: public insurance coverage, non-digestive or non-gastrointestinal (GI) surgery, outpatient prescription receipt for weaker opioids (i.e. codeine/tramadol), and concurrent depression and post-traumatic stress disorder (PTSD) diagnoses (Figure 1). Prognostic scores ranged from 1-9 (mean: 5, SD=2.7). Patients were stratified into three risk categories by prognostic score (1-4; 5-7; 8-9) with associated risk scores of 52.1% (95% CI: 48.9-55.2%), 68.6% (66.5-71.1%), 86.2% (76.6%-94.4%), respectively (Figure 2). CONCLUSIONS We developed a practical scoring system to stratify AYA with IBD by chronic opioid use risk. Future directions include understanding the relationship between these risk factors and their influence on chronic use. Risk factors most associated with chronic opioid use among AYA with IBD included: public insurance coverage, undergoing a non-digestive surgical procedure, and having concurrent diagnoses of depression and PTSD. Findings will directly inform targeted opioid reduction initiatives for this vulnerable population. Figure 1 Final risk factors associated with development of prognostic score.

Treatment completion, asparaginase completion, and oncologic outcomes among children, adolescents and young adults with acute lymphoblastic leukemia treated with DFCI Consortium Protocols.

Adolescents and young adult (AYA) patients with acute lymphoblastic leukemia (ALL) face worse outcomes than children. While pediatric-inspired protocols have improved outcomes, the ability of patients to complete these intensive regimens and the reasons for discontinuation are unknown. We analyzed a cohort of 332 AYA patients (aged 15-49 years) and 1159 children (aged 1-14 years) with Ph-negative ALL treated on DFCI consortium protocols. We found that AYA patients completed treatment at lower rates than children (60.8% vs. 89.7%, p < 0.001), primarily due to higher rates of early treatment failure (14.5% vs. 2.4%, p < 0.001). Withdrawal from treatment for toxicity, social/personal, or unknown reasons was uncommon, but higher among AYA patients (9.3% vs 4.7%, p = 0.001). Patients who remained on assigned therapy for one year had favorable overall survival (AYA 5-year OS 88.9%; children 5-year OS 96.4%; p < 0.001). Among patients who continued treatment for 1 year, AYA patients completed asparaginase (defined as receiving 26+ weeks) at lower rates than children (79.1% vs. 89.6%, p < 0.001). Patients who received more weeks of consolidation asparaginase had higher overall and event-free survival. Efforts should focus on identifying patients at risk for early treatment failure and optimizing asparaginase delivery.

Developing a transition workshop for adolescents with sickle cell disease

BackgroundThe transfer from paediatric to adult care presents a significant challenge for adolescents and young adults (AYA) with sickle cell disease (SCD). Disease self-management skills have been recognized as important mediators of poor health outcomes, but transition-related skills such as scheduling appointments and understanding the shift in health care responsibilities remain under taught in the healthcare system. The purpose of this quality improvement (QI) study was to (1) understand the areas of disease self-management that AYA patients felt underprepared for, and (2) design and evaluate an educational program addressing the top unmet skills. MethodsThe Plan-Do-Study-Act (PDSA) model was implemented in a tertiary outpatient clinic between September 2020 and July 2021. Patients were surveyed during regular clinic visits to identify their priorities on disease self-management skills. Based on the results, a virtual workshop was created and administered three separate times. Feedback was collected using an electronic survey. Results‘Navigating the adult health care system’ was the top self-management skill that AYA patients (n = 39) identified needing more support with. The majority of participants (79%, n = 14) reported that the virtual workshop was excellent, with ‘appointment management’ being the most useful topic discussed. Participants also reported feeling more confident (71%) and aware (86%) of how to navigate adult care. ConclusionThis QI study showed that delivering a virtual workshop on transition skills was well received by AYA participants with SCD. The PDSA framework was useful for identifying specific knowledge gaps in transition aged AYA to help improve patient education in a well-established transition program.
