Dietary intake, antioxidants, minerals and vitamins in relation to childhood asthma: a Mendelian randomization study.

Background: Currently, there is limited and inconsistent evidence regarding the risk association between daily dietary intake, antioxidants, minerals, and vitamins with Childhood Asthma (CA). Therefore, this study employs Mendelian Randomization (MR) methodology to systematically investigate the causal relationships between daily dietary intake, serum antioxidants, serum minerals, and the circulating levels of serum vitamins with CA. Methods: This study selected factors related to daily dietary intake, including carbohydrates, proteins, fats, and sugars, as well as serum antioxidant levels (lycopene, uric acid, and ß-carotene), minerals (calcium, copper, selenium, zinc, iron, phosphorus, and magnesium), and vitamins (vitamin A, vitamin B6, folate, vitamin B12, vitamin C, vitamin D, and vitamin E), using them as Instrumental Variables (IVs). Genetic data related to CA were obtained from the FinnGen and GWAS Catalog databases, with the primary analytical methods being Inverse Variance Weighting (IVW) and sensitivity analysis. Results: Following MR analysis, it is observed that sugar intake (OR: 0.71, 95% CI: 0.55-0.91, P: 0.01) is inversely correlated with the risk of CA, while the intake of serum circulating magnesium levels (OR: 1.63, 95% CI: 1.06-2.53, P: 0.03), fats (OR: 1.44, 95% CI: 1.06-1.95, P: 0.02), and serum vitamin D levels (OR: 1.14, 95% CI: 1.04-1.25, P: 0.02) are positively associated with an increased risk of CA. Conclusion: This study identified a causal relationship between the daily dietary intake of sugars and fats, as well as the magnesium and vitamin D levels in serum, and the occurrence of CA. However, further in-depth research is warranted to elucidate the specific mechanisms underlying these associations.

Adverse childhood experiences (ACEs) association with Melanoma.

Adverse Childhood Experiences (ACEs) are forms of abuse, neglect, or household dysfunction before the age of 18. We found individuals exposed to ACEs are at increased odds of receiving a melanoma diagnosis. ACEs range from people whose parents divorced in childhood (OR 1.64) to people who were physically hurt by their parents (OR 2.41).

Targeting pediatric solid tumors in the new era of RNA therapeutics.

Despite substantial progress in pediatric cancer treatment, poor prognosis remained for patients with recurrent or metastatic disease, given the limitations of approved targeted treatments and immunotherapies. RNA therapeutics offer significant potential for addressing a broad spectrum of diseases, including cancer. Advances in manufacturing and delivery systems are paving the way for the rapid development of therapeutic RNAs for clinical applications. This review summarizes therapeutic RNA classifications and the mechanisms of action, highlighting their potential in manipulating major cancer-related pathways and biological effects. We also focus on the pre-clinical investigation of RNA molecules with efficient delivery systems for their therapeutic potential targeting pediatric solid tumors.

Infant embodied requests and teacher-practitioner offers during early childhood education mealtimes.

The importance of building healthy relationships with food in children's early years is of paramount importance. Building on prior work exploring the social and linguistic practices in infant eating interaction experiences, this research uses a multimodal conversation analysis approach to explore how mealtime interactions are managed as a co-constructed activity between infants (0-2 years) and early childhood teacher-practitioners. Here we will explore video data recorded during mealtimes in an early childhood setting in Mid-Wales, where infants orient to recruitments for assistance and teachers provide offers of help with food items throughout the data. Analysis demonstrates 1) infant recruitment of help through embodied 'showing' an item causing a problem in multimodal ways, initiating joint attention that mobilises an offer from an adult in the shape of 'do you want me to X' and 2) adult initiation of an offer of help in the shape of 'would you like me to X' that are not prompted by infants 'showing' an item. Such practices demonstrate infant social competence in recruiting assistance through multimodal resources, and adult's noticings that help is required and their initiation of provision of assistance. The detailed exploration into the ways in which mealtimes are a collaboratively achieved experience reveals how infants effectively contribute in resourceful ways, and how teacher-practitioner responses frame mealtimes as co-produced activities.

Long-term visual outcomes and ocular complications in children with Marner's hereditary cataracts operated in the period 1940-2021.

PURPOSE: To investigate visual development and long-term complications after cataract surgery in childhood. METHODS: This cross-sectional study included patients from a family with Marner's hereditary cataracts who had cataract surgery before 18 years of age. The study was conducted from 1 January 2022 until 31 December 2022. The patients contributed to their medical files and participated in an updated ophthalmologic examination. RESULTS: We included 52 patients (101 eyes, 34 females). The median age at cataract surgery was 7 years (IQR: 5-10) and the age at examination was 40 years (IQR: 21-54). Primary and secondary intraocular lens implantation had been performed in 47.5% (25 patients, 48 eyes) and 16.8% (10 patients, 17 eyes). Visual acuity was ≤0.3 logMAR in 77% (78 eyes), and <0.5 logMAR in 8% (8 eyes). Glaucoma was present in 17% (9 patients, 12 eyes), ocular hypertension in 6% (3 patients, 4 eyes), and 10% (5 patients, 5 eyes) had prior retinal detachment. Mild visual field loss (2 < mean defect (MD) ≤ 6 dB) was found in 62% (63 eyes) and moderate to advanced visual field loss (MD > 6 dB) in 24% (24 eyes). Thirty-five patients (67%) held a driver's licence, and three were not allowed to drive due to low visual function. All patients were employed. CONCLUSION: After cataract surgery in childhood, many patients achieve normal visual acuity, but mild visual field loss is common. Long-term follow-up is important due to the high risk of glaucoma.

A preliminary examination of the effects of childhood abuse and resilience on pain and physical functioning in patients with knee osteoarthritis.

OBJECTIVES: We examined associations of a self-reported history of childhood abuse with pain and physical functioning in patients with knee osteoarthritis (KOA) awaiting total knee arthroplasty (TKA). We also explored the potential moderating effects of positive childhood experiences (PCEs), an index of resilience, on these associations. METHODS: Prior to TKA, participants with KOA awaiting surgery (N = 239) completed self-report measures of adverse childhood experiences (ACEs), PCEs, pain, and physical functioning. We evaluated associations of pain and physical functioning (Brief Pain Inventory [BPI] and Western Ontario and McMaster University of Osteoarthritis Index [WOMAC]) based on the experience of ACEs (childhood abuse), with PCEs (childhood happiness and supportive parental care) as potential moderators. RESULTS: Greater exposure to childhood abuse was positively correlated with BPI pain interference as well as WOMAC pain and functioning scores. Additionally, childhood happiness and supportive parental care moderated the positive associations of childhood abuse with pain and physical functioning; though, surprisingly, the adverse effects of childhood abuse on these outcomes were more pronounced among participants with high levels of childhood happiness and supportive parental care. CONCLUSION: Overall, results show an association between a self-reported history of childhood abuse and pain and functioning in patients with KOA awaiting TKA. However, PCEs did not protect against the negative consequences of childhood abuse in our cohort. Further research is needed to validate these associations and gain a more comprehensive understanding of the complex interplay between childhood abuse and PCEs and their potential influences on pain experiences in adults with chronic pain conditions, including KOA.

Improved HPLC method with automated pre-column sample derivatisation for serum pegylated L-asparaginase activity measurement in paediatric acute lymphoblastic leukaemia patients.

Therapeutic drug monitoring of pegylated L-asparaginase (ASNase) ensures the drug effectiveness in childhood acute lymphoblastic leukaemia (ALL) patients. The biological drug property with variable immunogenic host clearance, and the prescription of its generic formulation urge the need for a reliable assay to ensure an optimal treatment and improve outcome. This study aimed to optimise an existing isocratic reversed-phase high performance liquid chromatography (RP-HPLC) method with an automated pre-column sample derivatisation and injection program, and a computational algorithm for measuring serum pegylated ASNase activity in children with ALL. Nath et al.'s method in 2009 was adopted and modified using a pegylated ASNase. A set of Microsoft Excel macros was developed for the serum drug activity computation. An Agilent InfinityLab LC Series 1260 Infinity II Quaternary System with fluorescence detection was employed with an Agilent Poroshell 120 EC-C18 4.6×100 mm, 2.7 µm analytical column. System flow rate was optimised to 2.0 mL/min with 40×10-6/bar pump compressibility. The O-phthaldialdehyde (OPA) solution composition was optimised to 1 % o-phthaldialdehyde, 0.8 % 2-mercaptoethanol, 7.13 % methanol, and 1.81 % sodium tetraborate. The pre-column derivatisation program mixed 0.1 µL sample with 25 µL OPA solution before the automated injection. Method validation was according to the ICH guidelines. Total analysis time was 15 min, with L-aspartic acid eluted at 0.96 min and internal standard at 4.7 min. The calibration curves showed excellent linearity (R ≥0.9999). Interday precision for the drug activity at 0.1 IU/mL, 0.5 IU/mL, and 1 IU/mL were 4.15 %, 3.05 %, and 3.09 % (n = 6). Mean %error for the drug activity at 0.1 IU/mL, 0.5 IU/mL, and 1 IU/mL were 0.90±4.41 %, -1.37±3.04 %, and -3.03±3.02 % (n = 6). Limit of quantitation was 0.03 IU/mL. Majority of the patients' serum drug activity fell within the assay calibration range. Our improved method is automated, having shorter analysis time with a well-maintained separation resolution that enables a high-throughput analysis for application.

Health-related quality of life in children with childhood acute myeloid leukemia in China: A five-year prospective study.

Purpose: This study aims to identify the key factors influencing health-related quality of life (HRQoL) of pediatric acute myeloid leukemia (AML) patients following their initial diagnosis and examine their impact on the five-year survival prognosis. Methods: A chart review and follow-up were conducted for children with AML who participated in a prospective cohort study between 2017 and 2020. We identified factors influencing HRQoL through Pediatric Quality of Life Inventory™ (PedsQL™ 4.0), PedsQL™ Cancer Module 3.0 (CM 3.0) and PedsQL™ Family Impact Module 2.0 (FIM 2.0), as well as assessed the impact of impaired HRQoL on the overall outcomes of patients. Results: Sixty-four subjects enrolled in the study had complete HRQoL outcome data, and 61 of them completed the 5-year follow-up. In CM 3.0, age was positively associated with parental proxy reports (p = 0.040), whereas divorced families were negatively associated with child self-reports (p = 0.045). A positive medical history correlates with FIM 2.0 (p = 0.025). Residence (p = 0.046), the occupation of caregivers (p = 0.014), disease severity (p = 0.024), and the only child (p = 0.029) exhibited statistically significant associations with the impairment of HRQoL. Impaired HRQoL scores shown by the PedsQL™4.0 parent proxy report (p = 0.013) and FIM 2.0 (p = 0.011) were associated with a reduced 5-year survival rate. Conclusions: This study demonstrated that early impairment of HRQoL in pediatric acute myeloid leukemia patients has predictive value for long-term prognosis. Once validated, these findings may provide some guidance to clinicians treating children with AML.

Enhanced aortic stiffness in adolescents with chronic disease is associated with decreased left ventricular global longitudinal strain.

Background: The recent Cardiovascular Disease in Adolescents with Chronic Disease (CDACD) study showed enhanced aortic stiffness and wall thickness in adolescents with various chronic disorders. Enhanced aortic stiffness can increase left ventricular (LV) afterload and trigger a cascade of adverse arterioventricular interaction. Here, we investigate the relation between aortic changes and LV function in the CDACD study participants. Methods: This cross-sectional study included 114 adolescents 12-18 years old with cystic fibrosis (CF, n = 24), corrected coarctation of the aorta (CoA, n = 25), juvenile idiopathic arthritis (JIA, n = 20), obesity (n = 20), and healthy controls (n = 25). Aortic pulse wave velocity (PWV), which reflects aortic stiffness, and aortic wall thickness (AWT) were assessed with cardiovascular magnetic resonance imaging (CMR). Echocardiography was employed to study conventional markers of LV function, as well as LV global longitudinal strain (LVGLS), which is an established (pre)clinical marker of LV dysfunction. Results: First, aortic PWV and AWT were increased in all chronic disease groups, compared to controls. Second, in adolescents with CoA, JIA, and obesity, echocardiography showed a decreased LVGLS, while LV dimensions and conventional LV function markers were similar to controls. Third, multivariable linear regression identified aortic PWV as the most important determinant of their decreased LVGLS (standardized ß -0.522, p < 0.001). Conclusions: The decreased LVGLS in several adolescent chronic disease groups was associated with enhanced aortic PWV, which might reflect adverse arterioventricular interaction. Whether the decreased LVGLS in the chronic disease groups could negatively impact their long-term cardiovascular outcomes requires further study.

Stressful life events and the occurrence of skin cancer.

OBJECTIVE: It is widely acknowledged that emotional states can influence skin conditions, yet limited research has delved into the impact of stress on skin cancer development. This retrospective study sought to expand the perspective on skin cancer risk factors by investigating the complex relationship between stressful life events and the incidence of skin cancer. METHODS: The sample included 268 individuals followed-up in a dermatological clinic, in three groups: Patients who had previously been diagnosed with cutaneous melanoma and are currently in remission (32%), those who had been diagnosed with non-melanoma skin cancer (30%), and a control group who are at risk for skin cancer (38%). Participants filled in questionnaires regarding childhood and adulthood life events, and loss and gain of resources following their subjectively most stressful event in adulthood. Multinomial logistic regression was used to examine the associations of life events with skin cancer occurrence, and mediating and moderating effects of resource loss/gain. RESULTS: Adverse childhood experiences were associated with melanoma occurrence, with the melanoma group reporting significantly more such experiences compared to the control group (p < 0.001). Resource loss from subjectively significant stressful life events in adulthood partially mediated the association between adverse childhood experiences and melanoma incidence. CONCLUSIONS: The findings suggest that there may be intricate connections between stress, life events, adaptation to change, and skin cancer, which future research may further unravel. This study underscores the need for a more comprehensive approach to stress management, coping strategies development, and skin cancer prevention in healthcare settings.

"You can be cured, but cancer never leaves you behind": an interdisciplinary approach into the embodied cancer experiences among adult Colombian childhood/adolescent cancer survivors.

PURPOSE: Childhood or adolescent cancer survivors (CACS) are an understudied population in Colombia and, in general, in Central and South America. Worldwide, studies typically focus on high-income settings while approaching CACS' experiences from a biomedical or psychological perspective. However, both perspectives miss an important aspect of survivorship after childhood or adolescent cancer: the affected individual's subjective experiences of having a disabled body. This qualitative study aimed to explore the embodied experiences of Colombian adults who survived cancer during their childhood or adolescence to better understand how CACS relate to their altered body and world. METHODS: By integrating phenomenological insights and conducting comprehensive life-story interviews, we explored the various ways in which survivors' cancer experiences affect their bodily sense of self-from the acute phase of the disease until well into adulthood. A total of ten life-stories interviews and one focus group were carried out with seven CACS. All participants were survivors of a different type of childhood/adolescent cancer. The results were analyzed thematically, focusing on the embodied aspects of participants' experiences. RESULTS: We developed three main themes regarding the embodied cancer experience among participating CACS: Firstly, participants' body changes because of the cancer and its treatment, which makes them aware of their body. Secondly, they adapt to this experience in different bodily ways. Finally, they carry bodily traces of their cancer experience in the present as well as into the future. CONCLUSIONS: The CACS participating in this study report that their experience with cancer has been embodied throughout their lives, changing their sense of their body and how they relate to it, and leaving traces into the present and their imagined future.

Gender differences in the association between adverse childhood experiences and premature mortality: A prospective population study.

BACKGROUND: Birth cohort studies have shown that adverse childhood experiences (ACEs) are associated with all-cause mortality. The effect of ACEs on premature mortality among working-age people is less clear and may differ between the genders. OBJECTIVE: In this prospective population study, we investigated the association of ACEs with all-cause mortality in a working-age population. PARTICIPANTS AND METHODS: In a representative Finnish population study, Health 2000, individuals aged 30 to 64 years were interviewed in 2000, and their deaths were registered until 2020. At baseline, the participants (n = 4981, 2624 females) completed a questionnaire that included 11 questions on ACEs and questions on tobacco smoking, alcohol abuse, self-reported health and sufficiency of income. All-cause mortality was analysed by Cox regression analysis. RESULTS: Of the ACEs, financial difficulties, parental unemployment and individual's own chronic illness were associated with mortality. High number (4+) of ACEs was significantly associated with all-cause mortality in females (HR 2.11, p < 0.001), not in males. Poor health behaviour, self-reported health and low income were the major predictors of mortality in both genders. When the effects of these factors were controlled, childhood family conflicts associated with mortality in both genders. CONCLUSIONS: Among working-age people, females seem to be sensitive to the effects of numerous adverse childhood experiences, exhibiting higher premature all-cause mortality. Of the individual ACEs, family conflicts may increase risk of premature mortality in both genders. The effect of ACEs on premature mortality may partly be mediated via poor adult health behaviour and low socioeconomic status. WHAT IS ALREADY KNOWN: In birth cohort studies, adverse childhood experiences (ACEs) have been associated with all-cause mortality. In working-age people, the association of ACEs with premature mortality is less clear and may differ between the genders. WHAT THIS STUDY ADDS: In working-age people, high number of ACEs associate with all-cause premature mortality in females, not in males. The effect of ACEs on premature mortality may partly be mediated via poor adult health behaviour, self-reported health and low socioeconomic status.

Who is in Your Waiting Room? Social Determinants of Health and Adverse Childhood Experiences in Pediatric Surgery Clinics.

BACKGROUND: Social determinants of health (SDoH) influence overall health, although little is known about the SDoH for pediatric patients requiring surgical services. This study aims to describe SDoH for pediatric surgical patients attending out-patient, community, and outreach clinics, as well as demonstrate the feasibility of identifying and addressing SDoH and Adverse Childhood Experiences (ACEs) when appropriate. METHODS: A cross-sectional study using surveys evaluating SDoH that were distributed to families attending pediatric surgical clinics over a two-year period. The pilot survey used validated questions and was later refined to a shorter version with questions on: Barriers to care, Economic factors, Adversity, Resiliency and Social capital (BEARS). Data was analyzed with descriptive and inferential statistics. RESULTS: 851 families across 13 clinics participated. One third of families reported not having a primary health care provider or being unable to turn to them for additional support. One in four families were found to have a household income less than the Canadian after-tax low-income threshold (<$40,000 CAD). Two-thirds of families answered questions about ACEs, and those with more ACEs were more likely to report a low income. Forty percent of families rarely or only sometimes had adequate social support. CONCLUSION: This survey tool enabled discussions between families and care providers, which allowed clinicians to appropriately follow-up with families and refer them to social work for further support when indicated. Addressing concerns around SDoH within a busy surgical clinical is feasible and may positively affect long-term health outcomes and equitable resource allocation. LEVEL OF EVIDENCE: IV.

Posterior reversible encephalopathy syndrome in immunocompromised children - A single-center study from South India.

This study describes the profile of children diagnosed with posterior reversible encephalopathy syndrome (PRES) in the pediatric hematology oncology unit and highlights the clinical features of PRES in immunosuppressed children. This retrospective study included 10 children diagnosed with PRES with a mean age of 6.8 years. Acute lymphoblastic leukemia was the most common primary diagnosis followed by post-hematopoietic stem cell transplant patients. Most cases of PRES occurred within one month of treatment initiation. Hypertension was noted in all at the time of diagnosis. Neuroimaging revealed bilateral lesions with parietal and occipital lobe involvement being the most common. All patients received corticosteroids as part of treatment for primary diagnosis. Controlling blood pressure was critical in managing PRES. Consideration of PRES as a clinical possibility in pediatric hematology oncology unit in children presenting with symptoms such as headache, seizures, and visual disturbances will aid in early diagnosis after ruling out other causes of these symptoms.

Factors affecting caregiver burden among parents of children with cancer: A path analysis.

AIMS: To investigate the relationships between parental resilience, illness perception and pain catastrophizing as factors affecting caregiver burden among parents of children with cancer, based on the Transactional Model of Stress and Coping. BACKGROUND: Parents, as the primary caregivers of children with cancer, often face universal challenges. These include adverse health impacts, work, financial disruptions, strained social and family relationships, and the need for specialised support and intervention. DESIGN: A cross-sectional design using path analysis. METHODS: The STROBE guidelines for cross-sectional studies were followed. An online questionnaire was distributed through Facebook pages operated by various organisations that support parents of children with cancer, such as 'The Israel Cancer Association', 'Giving Hope' and 'Hayim Association' from October 2021 to February 2022. The participants completed a questionnaire about demographic and child-related characteristics, resilience, illness perception, pain catastrophizing, social support and caregiver burden. Associations between the variables were explored using Pearson's correlations and path analyses. RESULTS: The study included 67 parents of children with cancer with an average age of 41.79 (SD = 6.31). The majority were mothers (n = 54, 80.6%) with a steady partner (n = 62, 92.5%). The level of caregiver burden was M (SD) = 25.00 (7.15) out of 48 possible, indicating a high burden level. Illness perception was directly positively associated with caregiver burden (ß = .280, p = .017) and pain catastrophizing (ß = .340, p < .01), and directly negatively with resilience (ß = -.318, p < .01). Illness perception and pain catastrophizing serially mediated the relationship between resilience and caregiver burden among parents of children with cancer (ß = -.190, p = .001). CONCLUSIONS: This study found that both illness perception and pain catastrophizing serially mediated the relationship between personal resilience and caregiver burden. RELEVANCE TO CLINICAL PRACTICE: To ease caregiver burden for parents of children with cancer, programmes should address their psychological and emotional needs, including managing perceptions of illness and coping with pain-related distress.

Morbidity and mortality among children, adolescents, and young adults with cancer over six decades: a Swedish population-based cohort study (the Rebuc study).

Background: Despite progress in managing cancer in children, adolescents, and young adults (CAYAs), persistent complications may impact their quality of life. This study covers the morbidity and mortality, among CAYAs, with the aim to investigate the influence of socioeconomic factors on outcomes. Methods: This retrospective matched cohort study included the entire Swedish population of individuals under 25 with cancer 1958-2021. The population was identified from the Cancer Register, and controls were paired 1:5 based on age, sex, and residence. Multiple registers provided data on morbidity, mortality, and demographics. Findings: This survey covering 63 years, identified 65,173 CAYAs and matched controls, a total of 378,108 individuals (74% females). CAYAs exhibited a 3.04-times higher risk for subsequent cancer (Odds ratio (OR) 95% confidence interval (CI) 2.92-3.17, p < 0.0001), a 1.23-times higher risk for cardiovascular disease (OR 95% CI 1.20-1.26, p < 0.0001), and a 1.41-times higher risk for external affliction (OR 95% CI 1.34-1.49, p < 0.0001). CAYAs had a higher mortality hazard, and after adjusting for socioeconomic factors, males, individuals born outside Europe, and those with greater sick-leave had a higher association with mortality, while education and marriage showed a beneficial association. Interpretation: The Rebuc study, showed an increased risk for serious complications among young cancer patients in Sweden. Patient-specific variables, demographics, and socioeconomic factors influenced mortality. These results underscore the impact of cancer on the health and lifespan of young individuals and the necessity for further research to address socioeconomic disparities in cancer care. Funding: Grants from the Medical Research Council of Southeast Sweden (FORSS), ALF Grants, Region Ostergotland, and The Swedish Childhood Cancer Fund.

Sexual health in adult survivors of childhood cancer: A Project REACH study.

BACKGROUND: Sexual dysfunction is a significant complication of treatment for many adult-onset cancers. However, comparatively less is known about sexual dysfunction in adult childhood cancer survivors (CCSs). Research has been limited by the exclusion of specific cancers (e.g., central nervous system [CNS] tumors) and the lack of validated measures, which makes it difficult to understand the nature and prevalence of sexual dysfunction in CCSs. METHODS: A total of 249 adult CCSs (aged 18-65 years) enrolled in Project REACH, a prospective cohort study, and completed measures of physical and mental health, including sexual dysfunction. Participants scoring ≤19 on the Female Sexual Function Index 6 or ≤21 on the International Index of Erectile Function 5 were classified as experiencing sexual dysfunction. Analyses examined the relationships between sexual dysfunction and demographic, disease, treatment, and health variables. RESULTS: A total of 78 participants (32%) experienced clinically significant sexual dysfunction. In univariate analysis, sexual dysfunction was significantly associated with CNS tumor diagnosis (odds ratio [OR], 2.56) and surgery (OR, 1.96) as well as with health variables such as fatigue (OR, 3.00), poor sleep (OR, 2.84), pain (OR, 2.04), depression (OR, 2.64), poor physical health (OR, 2.45), and poor mental health (OR, 2.21). Adjusted analyses found that CNS tumor diagnosis (p = .001) and health variables (p = .025) contribute significantly to sexual dysfunction in CCSs. CONCLUSIONS: Approximately one third of adult CCSs report clinically significant sexual dysfunction, which underscores a significant screening and treatment need. However, because available measures were developed for survivors of adult cancers, research to create a sexual health measure specifically for adult CCSs is necessary to better identify the sexual health concerns of this vulnerable population.

Exploring height outcomes with adjuvant aromatase inhibition in growth hormone-deficient male survivors of childhood cancer.

BACKGROUND: Aromatase inhibitors (AI) may improve height in short stature conditions; however, the effect in childhood cancer survivors (CCS) is unknown. We assessed final adult height (FAH) in CCS treated with AI and GH compared with those treated with GH alone. METHODS: Retrospective cohort study of GH-deficient male CCS treated between 2007 and 2023. FAH was noted as the height at the fusion of growth plates or 18 years of age. Multivariable linear regression was used to examine treatment association with FAH, adjusting for other risk factors. RESULTS: Ninety-two patients were included; 70 were treated with GH and 22 with combination AI/GH. The mean age at GH initiation did not differ between groups. The mean age at AI initiation was 13.7 ± 1.9 years. A greater proportion of patients in the AI/GH group were treated with stem cell transplantation, abdominal radiation, total body irradiation, and cis-retinoic acid (p < .01). Multivariable linear regression demonstrated no significant treatment association with FAH Z-score (ß = 0.04, 95% CI: -0.9 to 0.9). History of spinal radiation (ß = -0.93, 95% CI: -1.7 to -0.2), lower starting height Z-score (ß = -0.8, 95% CI: -1.2 to -0.4), and greater difference between bone age and chronological age (ß = -0.3, 95% CI: -0.5 to -0.07) were associated with lower FAH Z-score. CONCLUSIONS: Adjuvant AI was not associated with increased FAH in male CCS compared with GH monotherapy. Future work is needed to determine the optimal adjunctive treatment to maximize FAH for this population.

Prognostic factors in childhood vitiligo.

BACKGROUND: Vitiligo is a multifactorial disease characterized by the progressive loss of melanocytes. The worldwide prevalence ranges from 0.5% to 2%, and in children from 0% to 2.16%. The objective of this study was to determine the variables associated with progression of vitiligo. METHODS: A retrospective cohort was carried out where a random sample of records of pediatric patients with vitiligo from January 2016 to December 2020 was analyzed. The variables were studied: age at onset, sex, hereditary family history, personal history of thyroid diseases, time of evolution, classification, Köebner phenomena, mucosal vitiligo, halo nevus, premature graying and the presence of other dermatoses. The final state was classified as progression, stability, partial remission and complete remission. RESULTS: 574 children with vitiligo; 290 (50.5%) women, 284 (49.5%) men. Non-segmental vitiligo in 324 (56.4%), segmental vitiligo in 250 (43.6%). Mean age of onset 8.7 years (SD: 4.54). Median evolution time 6 months (25th percentile of 3 months and 75th percentile of 24 months). Family history 27 (4.70%). Thyroid disease 7 (1.21%). Evolution remained stable in 44 (7.7%), 68 (11.8%) had progression, 32 (5.6%) complete remission, 222 (38.7%) partial remission and 208 (36.2%) one consultation. Non-segmental vitiligo was obtained p < 0.028, younger age of onset p < 0.000, and none skin comorbidities p < 0.009. CONCLUSIONS: The variables that were associated with a more progression were non-segmental vitiligo, early ages at the onset of the disease, and not presenting with other skin diseases.

El estado final se clasificó en progresión, estabilidad, remisión parcial y remisión completa. RESULTADOS: 574 niños con vitiligo; 290 (50.5%) mujeres y 284 (49.5%) varones. Vitiligo no segmentario en 324 (56.4%), vitiligo segmentario en 250 (43.6%). Edad promedio de aparición 8.7 años (DE: 4.54). Mediana de tiempo de evolución 6 meses (percentil 25 de 3 meses y percentil 75 de 24 meses). Se encontraron antecedentes familiares en 27 (4.70%). Enfermedad tiroidea en 7 (1.21%). En la evolución permanecieron estables 44 (7.7%), progresaron 68 (11.8%), remisión completa 32 (5.6%), remisión parcial 222 (38.7%) y una consulta 208 (36.2%). Se obtuvo p < 0.028 en vitiligo no segmentario, p < 0.000 en menor edad de aparición y p < 0.009 en comorbilidad cutánea. CONCLUSIONES: Las variables que se asociaron a progresión fueron vitiligo no segmentario, edad temprana de inicio y no cursar con otras enfermedades cutáneas.

Dental management of long-term childhood cancer survivors: a systematic review.

PURPOSE: Critically review and summarise existing knowledge on prevalence of oral, dental, and craniofacial side-effects of antineoplastic treatment in childhood cancer survivors (CCS). METHODS: A literature search was conducted for studies reporting on children aged 4-19 years treated for any type of malignancy up to the age of 15 years and for whom, at the time of the examination, more than 8 months have elapsed since the end of treatment. Data regarding dental late effects on teeth and craniofacial complex were collected and mean prevalence of each defect was reported. RESULTS: From the 800 articles identified, 17 studies fulfilled inclusion criteria and were included. A total of 983 CCS were examined, with the total number of healthy controls being 1266 children. Haematological malignancy was the most prevalent diagnosis with the age at diagnosis ranging between 0-15 years. Multiple antineoplastic protocols were implemented with the elapsed time being 8 months up to 17 years. One-third of CCS experienced at least one late effect, with corresponding value for the control group being below 25%. Among the defects identified clinically, microdontia, hypodontia and enamel developmental defects were recorded in 1/4 of CCS. Impaired root growth and agenesis were the two defects mostly recorded radiographically. The effect on dental maturity and on salivary glands was unclear. CONCLUSION: CCS are at risk of developing dental late effects because of their disease and its treatment and therefore, routine periodic examinations are essential to record their development and provide comprehensive oral healthcare.
