Sequelae and post-thrombotic syndrome after venous thromboembolism in acute lymphoblastic leukemia survivors treated on the NOPHO ALL2008 protocol.

The treatment of acute lymphoblastic leukemia (ALL) is frequently complicated by toxicity, including venous thromboembolism (VTE) affecting roughly 8% of patients. VTE can lead to post-thrombotic syndrome (PTS), a group of signs and symptoms developed as a complication to deep venous thrombosis (DVT), imposing risk of permanent disability and reduced quality of life (QoL). PTS prevalence ranges from 0% to 70%, reflecting very heterogenous cohorts and assessment tools. We aimed to estimate sequelae, including PTS and QoL in children and adults (<45 years old) who had a DVT during ALL treatment. PTS and QoL scores were obtained through use of Villalta and Modified Villalta Scale, PedsQL, and Short Form-36 questionnaires. The cohort comprised 20 children (<18 years) and seven adults (median age: 12.9 years, range: 2-44 years) at the time of DVT diagnosis. In total, 25 ALL survivors underwent PTS examination. The examination took place when survivors were 7-48 years (median age: 20.3 years, median follow-up time 6.8 years). QoL was assessed correlating cases with three matching ALL survivors without VTE. Two adults (15.4%) showed mild or moderate PTS. Eight children (66.7%) were diagnosed with mild PTS, while three cases had collaterals as sole symptoms. Pain or symptoms affecting daily life were reported by 16%. No difference in QoL was found (p = .9). This study underscores the need for comprehensive population-based investigations with validation of PTS instruments in ALL survivors.

Sex-and age-related variations in myocardial tissue composition of the healthy heart: A native T1 mapping cohort study.

AIMS: Cardiovascular diseases manifest differently in males and females, potentially influenced by inherent sex- and age-related differences in myocardial tissue composition. Such inherent differences are not well-established in the literature. With this study using cardiac magnetic resonance (CMR) native T1 mapping, we aim to determine the effect of sex and age on myocardial tissue composition in healthy individuals. METHODS AND RESULTS: CMR native T1 mapping was performed in 276 healthy individuals (55% male, age 8---84 years) on a 1.5 Tesla scanner using a MOLLI 5(3)3 acquisition scheme. Additionally, 30 healthy participants (47% male, age 24-68 years) underwent a 1-year follow-up CMR to assess the longitudinal changes of native T1. Mean native T1 values were 1000±22 ms in males and 1022±23 ms in females (mean difference [MD]=22 ms, 95% CI [17, 27]). Female sex was associated with higher native T1 in multivariable linear regression adjusting for age, heart rate, left ventricular mass index, and blood T1 (ß=10 ms, 95% CI [3.4, 15.8]). There was no significant interaction between sex and age (p=0.27). Further, age was not associated with native T1 (ß=0.1 ms, 95% CI [-0.02, 0.2]), and native T1 did not change during a 1-year period (MD -4 ms, 95% CI [-11, 3]). CONCLUSION: Female sex was associated with higher native T1; however, there was no association between age and native T1. Additionally, there was no evidence of an interaction between sex and age. Our findings indicate intrinsic sex-based disparities in myocardial tissue composition.

Pancreas-related persisting sequelae in ALL survivors with a history of asparaginase-associated pancreatitis: A part of the ALL-STAR study.

OBJECTIVES: Asparaginase-associated pancreatitis (AAP) occurs in up to 18% of patients treated for acute lymphoblastic leukemia (ALL); however, long-term sequelae are largely unexplored. We aimed to explore pancreatic sequelae among ALL survivors with and without AAP. METHODS: We investigated pancreatic sequelae in a national cohort of ALL survivors, aged 1-45 years at ALL diagnosis treated according to the NOPHO-ALL2008 protocol and included sex- and age-matched community controls. RESULTS: We included 368 survivors (median follow-up 6.9 years), including 47 survivors with AAP and 369 controls. The p-lipase and p-pancreas-type amylase levels were lower in AAP survivors compared with both non-AAP survivors (Medians: 23 U/L [IQR 14-32] and 18 U/L [IQR 10-25] versus 29 [IQR 24-35] and 22 [17-28], p < .001 and p = .002) and community controls (28 U/L [IQR 22-33] and 21 U/L [IQR 17-26], both p < .006). Fecal-elastase was more frequently reduced in AAP survivors compared with non-AAP survivors (7/31 vs. 4/144, p = .001). Persisting pancreatic sequelae were found in 15/47 of AAP survivors and 20/323 of non-AAP survivors (p < .001), including diabetes mellitus in 2/39 of AAP survivors and 2/273 of non-AAP survivors. CONCLUSIONS: ALL survivors with AAP are at increased risk of persisting pancreatic dysfunction and require special attention during follow-up.

Children with cancer and their cardiorespiratory fitness and physical function-the long-term effects of a physical activity program during treatment: a multicenter non-randomized controlled trial.

PURPOSE: We aimed to determine the effects of a classmate-supported, supervised, in-hospital physical activity program during treatment primarily on cardiorespiratory fitness and secondarily on physical function. METHODS: A multicenter non-randomized controlled intervention study including children diagnosed with cancer, 6-18 years at diagnosis treated with chemo-/radiotherapy. The intervention comprised (i) an educational session on cancer in the child's school class; (ii) selection of two "ambassadors"-classmates who were co-admitted, supporting the child's everyday hospital life; and (iii) supervised in-hospital physical activity from diagnosis and throughout intensive treatment. One-year post-treatment, physical testing included cardiorespiratory fitness (primary outcome), Sit-to-Stand test, Timed-Up-and-Go, and Handgrip Strength. RESULTS: The intervention group included 75 of 120 children (61% boys, 13.4 ± 3.1 years); the control groups included 33 of 58 children with cancer (58% boys, 13.5 ± 2.5 years), and 94 age- and sex-matched children without a cancer history. One-year post-treatment, cardiorespiratory fitness tended to be higher in the intervention group (37.0 ± 6.0 mL/kg/min) than in the patient control group with cancer (32.3 ± 9.7 mL/kg/min) (mean difference 4.7 [0.4 to 9.1], p = 0.034). The intervention group performed better in the secondary outcomes. Compared with community controls, both patient groups had lower cardiorespiratory fitness. The patient control group had lower Sit-to-Stand, Timed Up and Go, and Handgrip Strength, while the intervention group had strength comparable to that of the community controls. CONCLUSIONS: Peer-supported, supervised, in-hospital physical activity during treatment may improve cardiorespiratory fitness and muscle strength 1-year post-treatment in children with cancer; however, survivors continue to have lower cardiorespiratory fitness than community controls. IMPLICATIONS FOR CANCER SURVIVORS: Children with cancer may benefit from in-hospital physical activity in improving long-term cardiorespiratory fitness and muscle strength.

Hyperlipidemia in children and adolescents with acute lymphoblastic leukemia: A systematic review and meta-analysis.

BACKGROUND: The established association between acute lymphoblastic leukemia (ALL) and hyperlipidemia has, in some studies, been linked to toxicities such as pancreatitis, thrombosis, and osteonecrosis. However, a systematic review investigating the incidence, management, and clinical implications of hyperlipidemia during childhood ALL treatment is lacking. OBJECTIVES: Systematically assess the incidence of hyperlipidemia during ALL treatment, explore associations with risk factors and severe toxicities (osteonecrosis, thrombosis, and pancreatitis), and review prevalent management strategies. METHODS: A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Data synthesis was descriptive, and a meta-analysis of hypertriglyceridemia and risk of severe toxicities was performed. RESULTS: We included 13 studies with 3,425 patients. Hyperlipidemia incidence varied widely (6.7%-85%) but with inconsistent definitions and screening strategies across studies. Evidence regarding risk factors was conflicting, but age (> 10 years) and treatment with asparaginase and glucocorticosteroids seem to be associated with hyperlipidemia. Hypertriglyceridemia (grade 3/4) increased the risk for osteonecrosis (odds ratio (OR): 4.27, 95% confidence interval (CI): 2.77-6.61). No association could be established for pancreatitis (OR: 1.60, 95% CI: 0.53-4.82) or thrombosis (OR: 2.45, 95% CI: 0.86-7.01), but larger studies are needed to confirm this. CONCLUSION: The overall evidence of this systematic review is limited by the small number of studies and risk of bias. Our review suggests that hypertriglyceridemia increases the risk for osteonecrosis. However, larger studies are needed to explore the clinical implications of hyperlipidemia and randomized trials investigating hyperlipidemia management and its impact on severe toxicities.

Long-term effects of asparaginase-associated pancreatitis.

Pancreatitis is a common and severe toxicity that occurs during asparaginase treatment for acute lymphoblastic leukemia, and has received increasing attention during the last decades. However, no consensus regarding follow-up exists. In this commentary, we highlight potential long-term health-related effects following asparaginase-associated pancreatitis, thereby providing clinicians with a framework when following these patients during and after cessation of therapy.

Physician-defined severe toxicities occurring during and after cancer treatment: Modified consensus definitions and clinical applicability in the evaluation of cancer treatment.

Overall survival after cancer is increasing for the majority of cancer types, but survivors can be burdened lifelong by treatment-related severe toxicities. Integration of long-term toxicities in treatment evaluation is not least important for children and young adults with cancers with high survival probability. We present modified consensus definitions of 21 previously published physician-defined Severe Toxicities (STs), each reflecting the most serious long-term treatment-related toxicities and representing an unacceptable price for cure. Applying the Severe Toxicity (ST) concept to real-world data required careful adjustments of the original consensus definitions, translating them into standardized endpoints for evaluating treatment-related outcomes to ensure that (1) the STs can be classified uniformly and prospectively across different cohorts, and (2) the ST definitions allow for valid statistical analyses. The current paper presents the resulting modified consensus definitions of the 21 STs proposed to be included in outcome reporting of cancer treatment.

Severe growth retardation in a newborn as a result of SARS-CoV-2 infection in the mother in the 23rd week of pregnancy.

Intrauterine growth restriction (IUGR) is a potential complication associated with maternal SARS-CoV-2 infection. Danish guidelines recommend ultrasound follow-up from gestational age (GA) 24+0 in SARS-CoV-2-positive pregnant women who experience reduced fetal movements. This is a case report of severe IUGR (-51%) after maternal infection at GA 22+1 in a healthy unvaccinated 28-year-old woman. Positive PCR-tests for SARS-CoV-2 from placenta and child, along with massive placental inflammatory findings, suggested IUGR caused by maternal infection. This implies that follow-up from earlier GA may be warranted.

Cerebral sinovenous thrombosis and asparaginase re-exposure in patients aged 1-45 years with acute lymphoblastic leukaemia: A NOPHO ALL2008 study.

Cerebral sinovenous thrombosis (CSVT) is a serious complication during asparaginase therapy in patients with acute lymphoblastic leukaemia (ALL). We identified 46 patients with CSVT among 2651 patients (1‒45 years) treated according to the Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL2008 protocol between 2008 and 2018. CSVT cases were prospectively registered in the NOPHO database with retrospective updates. We examined the frequency of asparaginase re-exposure after CSVT, potential factors associated with asparaginase truncation, and sequelae after CSVT. This work was supported by the Danish Cancer Society and the Danish Childhood Cancer Foundation. The 2.5-year cumulative incidence of CSVT was 1.9% (95% confidence interval 1.4%-2.5%). The majority of patients (74%, n = 31) were re-exposed to asparaginase (with low-molecular-weight heparin coverage), one of whom had a second CSVT, without neurological sequelae. Patients re-exposed to asparaginase were earlier in ALL treatment and lacked more asparaginase doses than non-re-exposed patients at CSVT diagnosis (median 50 vs. 81 days, p = 0.03; mean 11.2 vs. 8.4 asparaginase doses, p = 0.04). No other examined factors had an impact on asparaginase re-exposure. At the last follow-up (median 4.5 years after CSVT), 61% of patients had normal neurological status, and 57% had complete recanalisation of CSVT, with no significant difference between patients re-exposed and non-re-exposed to asparaginase. Our results indicate that re-exposure to asparaginase is safe after CSVT during anticoagulation.

Male Gonadal Function After Pediatric Hematopoietic Stem Cell Transplantation: A Systematic Review.

Male gonadal dysfunction is a frequent late effect after pediatric hematopoietic stem cell transplantation (HSCT) that can lead to disturbances in pubertal development, sexual dysfunction, and infertility. However, no systematic review exists regarding prevalence and risk factors in relation to different treatment regimens. We aimed to systematically evaluate the current evidence regarding the prevalence of male gonadal dysfunction after pediatric HSCT, related risk factors, and the diagnostic value of surrogate markers of spermatogenesis in this patient group. We searched PubMed and Embase using a combination of text words and subject terms. The eligibility screening was conducted using predefined criteria. Data were extracted corresponding to the Leydig cell compartment involved in testosterone production and the germ cell compartment involved in spermatogenesis, respectively. Subsequently, data synthesis was performed. Of 2369 identified records, 25 studies were eligible. The studies were heterogeneous in terms of included diagnoses, gonadotoxic therapy, follow-up time, and definitions of gonadal dysfunction. The data synthesis revealed a preserved Leydig cell function in patients treated with non-total body irradiation (TBI) regimens, whereas the evidence regarding the impact of TBI conditioning on Leydig cell function was conflicting. Based on surrogate markers of spermatogenesis and only limited data on semen quality, the germ cell compartment was affected in half of the patients treated with non-TBI regimens and in nearly all patients treated with TBI conditioning. Testicular irradiation as part of front-line therapy before referral to HSCT led to complete Leydig cell failure and germ cell failure. Evidence regarding the impact of diagnosis, pubertal stage at HSCT, and chronic graft-versus-host disease is limited, as is the evidence of the diagnostic value of surrogate markers of spermatogenesis. Testicular irradiation as part of front-line therapy and TBI conditioning are the main risk factors associated with male gonadal dysfunction after pediatric HSCT; however, impaired spermatogenesis is also observed in half of the patients treated with non-TBI regimens. Methodological shortcomings limit existing evidence, and future studies should include semen quality analyses, follow-up into late adulthood, and evaluation of the cumulative exposure to gonadotoxic therapy.

Endothelial dysfunction and thromboembolism in children, adolescents, and young adults with acute lymphoblastic leukemia.

Endothelial dysfunction has not previously been investigated as a thrombogenic risk factor among patients with acute lymphoblastic leukemia (ALL), known to be at high risk of thromboembolism. We retrospectively explored the association between three circulating biomarkers of endothelial dysfunction (thrombomodulin, syndecan-1, VEGFR-1) measured in prospectively collected blood samples and risk of thromboembolism in 55 cases and 165 time-matched controls, treated according to the NOPHO ALL2008 protocol. In age-, sex-, and risk group-adjusted analysis, increasing levels of thrombomodulin and VEGFR-1 were independently associated with increased odds of developing thromboembolism (OR 1.37 per 1 ng/mL [95% CI 1.20‒1.56, P < 0.0001] and OR 1.21 per 100 pg/mL [95% CI 1.02‒1.21, P = 0.005], respectively). These associations remained significant when including only samples drawn >30 days before thromboembolic diagnosis. Thrombomodulin levels were on average 3.2 ng/mL (95% CI 2.6-8.2 ng/mL) higher in samples with measurable asparaginase activity (P < 0.0001). Among single nucleotide variants located in or neighboring coding genes for the three biomarkers, none were significantly associated with odds of thromboembolism. If results are validated in another cohort, thrombomodulin and VEGFR-1 could serve as predictive biomarkers, identifying patients in need of preemptive antithrombotic prophylaxis.

Twelve tips for postgraduate interprofessional case-based learning.

Based on developing, implementing, and evaluating postgraduate interprofessional case-based learning, we have written these twelve tips for health education planners who wish to apply case-based learning in the clinical setting. Interprofessional case-based learning engages participants in a structured manner towards uncovering decisions processes and patterns of action that resemble the clinical reality in which various healthcare professionals handle multifaceted tasks related to the optimal patient treatment. Postgraduate interprofessional case-based learning has the potential to break down traditional hierarchical structures as interactions generate respectful behaviour. We present two models of case-based learning to assist in standardising, structuring, and systematising postgraduate interprofessional case-based learning. We have created 12 practical tips for the design, implementation, and evaluation of successful postgraduate interprofessional case-based learning integrated into the existing clinical setting.

Postgraduate Interprofessional Case-Based Learning in Childhood Cancer: A Feasibility Study.

This paper presents a feasibility study assessing the acceptability, demand, implementation, and practicality of postgraduate interprofessional case-based learning in childhood cancer at Copenhagen University Hospital-Rigshospitalet. Healthcare professionals included nurses, doctors, social workers, physiotherapists, occupational therapists, pharmacists, pharmacologists, dieticians, nursing assistants, and professionals with a supportive function (teachers, secretaries, priests, and daycare workers). All participated in a postgraduate interprofessional case-based learning session. Feasibility was assessed using Bowen's focus areas of acceptability, demand, implementation, and practicality. Before and after the intervention session, three measurement tools were used 2-3 weeks before participation and 3-4 weeks after participation to collect data: Assessment of Interprofessional Team Collaboration Scale, Readiness for Interprofessional Learning Scale, and Safety Attitudes Questionnaire. Representing 13 occupational groups, 49 participants completed the case-based learning sessions, indicating acceptability and practicality. The pre- and post-intervention questionnaires were completed by 79% of the participants, 88% of whom rated the professional content as good or very good. A change over time was detected on all three scales measuring mean difference post-intervention scores. The outcome measures can be used to assess the effect of the intervention. Postgraduate interprofessional case-based learning in childhood cancer is feasible in terms of acceptability, demand, implementation, and practicality. Implementation requires leadership commitment at all levels.

Severe toxicity free survival: physician-derived definitions of unacceptable long-term toxicities following acute lymphocytic leukaemia.

5-year overall survival rates have surpassed 90% for childhood acute lymphocytic leukaemia, but survivors are at risk for permanent health sequelae. Although event-free survival appropriately represents the outcome for cancers with poor overall survival, this metric is inadequate when cure rates are high but challenged by serious, persistent complications. Accordingly, a group of experts in paediatric haematology-oncology, representative of 17 international acute lymphocytic leukaemia study groups, launched an initiative to construct a measure, designated severe toxicity-free survival (STFS), to quantify the occurrence of physician-prioritised toxicities to be integrated with standard cancer outcome reporting. Five generic inclusion criteria (not present before cancer diagnosis, symptomatic, objectifiable, of unacceptable severity, permanent, or requiring unacceptable treatments) were used to assess 855 health conditions, which resulted in inclusion of 21 severe toxicities. Consensus definitions were reached through a modified Delphi process supplemented by two additional plenary meetings. The 21 severe toxicities include severe adverse health conditions that substantially affect activities of daily living and are refractory to therapy (eg, refractory seizures), are without therapeutic options (eg, blindness), or require substantially invasive treatment (eg, cardiac transplantation). Incorporation of STFS assessment into clinical trials has the potential to improve and diversify treatment strategies, focusing not only on traditional outcome events and overall survival but also the frequencies of the most severe toxicities. The two major aims of this Review were to: prioritise and define unacceptable long-term toxicity for patients with childhood acute lymphocytic leukaemia, and define how these toxicities should be combined into a composite quantity to be integrated with other reported outcomes. Although STFS quantifies the clinically unacceptable health tradeoff for cure using childhood acute lymphocytic leukaemia as a model disease, the prioritised severe toxicities are based on generic considerations of relevance to any other cancer diagnosis and age group.

Maintenance therapy and risk of osteonecrosis in children and young adults with acute lymphoblastic leukemia: a NOPHO ALL2008 sub-study.

PURPOSE: Osteonecrosis is a burdensome treatment-related toxicity that is mostly diagnosed during or soon after 6-mercaptopurine (6MP)/methotrexate (MTX) maintenance therapy for acute lymphoblastic leukemia (ALL), possibly indicating a pathogenic role of these drugs. METHODS: We prospectively registered symptomatic osteonecrosis during treatment of 1234 patients aged 1.0-45.9 years treated according to the Nordic Society of Hematology and Oncology (NOPHO) ALL2008 protocol. MTX/6MP metabolites were measured as part of the NOPHO ALL2008 maintenance therapy study. RESULTS: After a median follow-up of 5.6 years [interquartile range (IQR) 3.6-7.5], 68 patients had been diagnosed with symptomatic osteonecrosis. The cumulative incidence was 2.7% [95% confidence interval (CI) 1.6-3.8%] for patients aged < 10 years, 14.9% (95% CI 9.7-20.2%) for patients aged 10.0-17.9 years, and 14.4% (95% CI 8.0-20.8%) for patients aged ≥ 18 years. The median time from diagnosis of ALL to diagnosis of osteonecrosis in these age groups was 1.0 year (IQR 0.7-2.0), 2.0 years (IQR 1.1-2.4), and 2.2 years (IQR 1.8-2.8), respectively (p = 0.001). With 17,854 blood samples available for MTX and 6MP metabolite analysis, neither erythrocyte levels of 6-thioguanine (TG) nucleotides (p > 0.99), methylated 6MP metabolites (p = 0.37), MTX polyglutamates (p = 0.98) nor DNA-TG (p = 0.53) were significantly associated with the hazard of osteonecrosis in Cox models stratified by the three age groups and adjusted for sex. CONCLUSION: Maintenance therapy intensity determined by 6MP and MTX metabolites was not associated with the risk of developing osteonecrosis in the NOPHO ALL2008 cohort.

National, clinical cohort study of late effects among survivors of acute lymphoblastic leukaemia: the ALL-STAR study protocol.

INTRODUCTION: More than 90% of patients diagnosed with childhood acute lymphoblastic leukaemia (ALL) today will survive. However, half of the survivors are expected to experience therapy-related chronic or late occurring adverse effects, reducing quality of life. Insight into underlying risk trajectories is warranted. The aim of this study is to establish a Nordic, national childhood ALL survivor cohort, to be investigated for the total somatic and psychosocial treatment-related burden as well as associated risk factors, allowing subsequent linkage to nation-wide public health registers. METHODS AND ANALYSIS: This population-based observational cohort study includes clinical follow-up of a retrospective childhood ALL survivor cohort (n=475), treated according to a common Nordic ALL protocol during 2008-2018 in Denmark. The study includes matched controls. Primary endpoints are the cumulative incidence and cumulative burden of 197 health conditions, assessed through self-report and proxy-report questionnaires, medical chart validation, and clinical examinations. Secondary endpoints include organ-specific outcome, including cardiovascular and pulmonary function, physical performance, neuropathy, metabolic disturbances, hepatic and pancreatic function, bone health, oral and dental health, kidney function, puberty and fertility, fatigue, and psychosocial outcome. Therapy exposure, acute toxicities, and host genome variants are explored as risk factors. ETHICS AND DISSEMINATION: The study is approved by the Regional Ethics Committee for the Capital Region in Denmark (H-18035090/H-20006359) and by the Danish Data Protection Agency (VD-2018-519). Results will be published in peer-reviewed journals and are expected to guide interventions that will ameliorate the burden of therapy without compromising the chance of cure.

Interprofessional versus monoprofessional case-based learning in childhood cancer and the effect on healthcare professionals' knowledge and attitudes: study protocol for a randomised trial.

BACKGROUND: Interprofessional education in childhood cancer is a multifaceted field involving multiple healthcare professionals with general and specialised knowledge and skills. Complex treatment, care and rehabilitation require continuous professional development and maintenance of healthcare professionals' competencies in their field of expertise. However, limited knowledge exists in comparing interprofessional and monoprofessional education. Only a few randomised studies have evaluated the effectiveness and efficiency of interprofessional education. The objective of this single-centre, investigator-initiated cluster randomised trial is to study the effect of interprofessional versus monoprofessional case-based learning on healthcare professionals' knowledge of gastrointestinal side effects and attitudes towards team collaboration. METHODS: This study will randomise healthcare professionals to participate in either the experimental interprofessional group or the control monoprofessional group of case-based learning. The topic of the case-based intervention will be gastrointestinal side effects, one of six categories identified in a three-round Scandinavian Delphi study as relevant for interprofessional education in childhood cancer. The primary outcome is the self-reported questionnaire Assessment of Interprofessional Team Collaboration Scale. Secondary outcomes are measured by the self-reported questionnaires Readiness for Interprofessional Learning Scale Questionnaire, Safety Attitudes Questionnaire, and knowledge will be evaluated using a multiple-choice quiz. Participants will receive the self-reported questionnaires about 2 weeks before and 1 month after the intervention. On the day of the intervention, participants will answer a multiple-choice quiz before and after the case-based learning. Linear mixed models will be used to compare differences between the two groups in mean scores postintervention, adjusting for preintervention scores. DISCUSSION: This study will provide insight into the differences between interprofessional and monoprofessional case-based learning and how it affects healthcare professionals' knowledge of gastrointestinal side effects and attitudes towards team collaboration. TRIAL REGISTRATION: The intervention was registered at Clinical Trials.gov : NCT04204109 on December 102,019 and with the National Committee on Health Research Ethics: H-19087506 December 112,019 and the Danish Data Protection Agency: P-2019-637 October 152,019.

Everyday life challenges among adolescent and young adult survivors of childhood acute lymphoblastic leukemia: An in-depth qualitative study.

OBJECTIVE: As survival rates increase, growing numbers of childhood acute lymphoblastic leukemia (ALL) survivors are at risk for somatic and psychosocial late effects. Adolescent and young adult (AYA) survivors represent a distinct and vulnerable group. This study aimed to explore how AYA survivors of childhood ALL experience everyday life after cancer while adjusting to the potential impact of prior disease and treatment. METHODS: Semi-structured interviews were performed with survivors aged 15-22 years. Criterion-based homogenous purposive sampling was used to identify similarities within the group. Data were analyzed using an inductive, thematic approach. RESULTS: Data saturation occurred after 18 interviews. Identified themes included the post-chemo body, negotiating identities, and disruption. More than 80% reported physical or cognitive late effects, but survivors adapted to these and had a positive view on own health. However, a co-existing experience of frailty persisted. Social disruption during treatment had a negative impact on social relations even years following cure. Identity issues revolved around the paradox of seeking recognition for their cancer-related experiences, while also wanting to be treated like everyone else. Some participants aged 18-22 years experienced delayed reactions and a new, but unmet, need to process the past. CONCLUSIONS: AYA survivors of childhood ALL adapt well to their new life situations, but many experience ongoing cancer-related disruptions and experience not being fully understood. We suggest exploration and verbalization of these issues alongside somatic follow-up around the age of 16-18 years to support the AYA survivors during their transition into adulthood.

The outcome of antenatal ultrasound diagnosed anomalies of the kidney and urinary tract in a large Danish birth cohort.

OBJECTIVE: Antenatal ultrasound diagnosed anomalies of the kidney and urinary tract (AUDAKUT) are reported in 0.3%-5% on prenatal ultrasound (US) and 0.3%-4.5% on postnatal US. The anterior-posterior diameter of the renal pelvis (APD) is an essential measurement. Series with low threshold values of APD prenatally and postnatally will include healthy infants. It is important to avoid follow-up of such infants. INTERVENTIONS: In 2006, new Danish guidelines for AUDAKUT were introduced. AIM OF STUDY: Investigations of incidences and type of AUDAKUT based on Danish guidelines, including long-term follow-up. DESIGN: Cohort study. SETTING: Copenhagen University Hospital Hvidovre and Copenhagen University Hospital Rigshospitalet, Denmark. PATIENTS: Consecutive cases with AUDAKUT in the second and third trimesters, which were either terminated before 22 completed weeks of gestation or born in the 8-year period January 2006-December 2013. Patients were followed until June 2014. RESULTS: 50 193 live born children and 24 terminated fetuses (0.05%) were included. The prevalence of AUDAKUT was only 0.39% prenatally, 0.29% at first postnatal US and 0.22% at the end of follow-up, including terminated cases. The greater the prenatal and postnatal APD, the higher risk of febrile urinary tract infection (fUTI) and surgical intervention, and lower probability of resolution. 25% of the identified patients had fUTI and/or surgery. CONCLUSIONS: We recommend threshold values of APD at least 10 mm in the third trimester and in general at least 12 mm at first postnatal US for intensive follow-up. In this largest to date unselected birth cohort of AUDAKUT, the incidences of clinically significant AUDAKUT were in the lowest range of those previously published.
