RESUMO
BACKGROUND: The current Italian scenario of pediatric palliative care (PPC) services is characterized by inadequate coverage of the territory. Therefore, it is important to improve the referral of patients to the most appropriate setting (community care, general PPC, or specialized PPC) and to improve the delivery of PPC care. METHODS: Aiming at obtaining information about the referrals to the Padua Pediatric Hospice that could help estimate the investments needed to improve the provision of care, a retrospective analysis has been carried out. The rate of proper referral and discharge, the number of patients followed at the hospice, the mortality rate, and the length of follow-up were analyzed, and, when possible, data were stratified by oncological and non-oncological diseases. RESULTS: The analysis showed that of the 870 patients referred to the Padua Pediatric Hospice between 2008 and 2022, 76% were affected by non-oncological conditions. 82% of patients referred were taken in charge and most of the remaining patients have been inappropriately referred. The analysis showed a growing number of total referrals, which increased by 195% from 2008 to 2022. An increase in proper referrals and referrals of non-oncological patients was observed alongside a decrease in oncological patient referrals and a trend toward a decrease in discharge rates. A decreased mortality was observed in patients with non-oncological conditions, with only 6% of deceased patients in 2022. Moreover, a longer survival with a median follow-up length of 43 months was observed among patients with non-oncological conditions who were followed up at the Padua Pediatric Hospice for more than 12 months. Conversely, the short survival rate observed for oncological patients suggests that those patients should have been referred to PPC earlier to benefit from palliative care for longer periods. CONCLUSIONS: Considering these data, it is expected that the number of patients needing PPC services will steadily increase in the next years. Hence, there is a need to invest resources to provide the best care delivery model encompassing specific pathways for the transition into adulthood, the establishment of networks within all the Italian regions, and an efficient referral to the more suitable setting of care.

BACKGROUND: Children with medical complexity (CMC) often require multiple medications, leading to polypharmacy, which seems to be linked to adverse effects, administration errors, and increased caregiver burden. This study aimed to describe the prevalence of polypharmacy, medication burden, off-label drug use, and associated costs. METHODS: Conducted at the Pediatric Palliative Care Center of Padua, Italy, from August to October 2021, this cross-sectional observational study included patients up to 23 years old with at least one prescribed drug. Data were collected from medical records and caregiver interviews. Drug costs were collected from the Italian Medicine Agency. Descriptive statistical analysis was performed. For comparisons among categorical variables, the Chi-square test was used, and for those among continuous variables, the ANOVA test was used. RESULTS: This study analyzed treatment regimens of 169 patients with a median age of 12.5 years (0.3-23). Polypharmacy was present in 52.7% of patients, and medication burden was observed in 44.4%, both varying significantly by primary diagnosis (p < 0.001). The median daily cost per patient was EUR 2.2 (IQR 0.9-7.1), with significant variation among subgroups. Only 34.6% of prescriptions were off-label. CONCLUSIONS: polypharmacy and medication burden are frequent among our CMC population, with some differences according to primary diagnosis.
RESUMO
Coenzyme Q (CoQ) is a redox lipid that fulfills critical functions in cellular bioenergetics and homeostasis. CoQ is synthesized by a multi-step pathway that involves several COQ proteins. Two steps of the eukaryotic pathway, the decarboxylation and hydroxylation of position C1, have remained uncharacterized. Here, we provide evidence that these two reactions occur in a single oxidative decarboxylation step catalyzed by COQ4. We demonstrate that COQ4 complements an Escherichia coli strain deficient for C1 decarboxylation and hydroxylation and that COQ4 displays oxidative decarboxylation activity in the non-CoQ producer Corynebacterium glutamicum. Overall, our results substantiate that COQ4 contributes to CoQ biosynthesis, not only via its previously proposed structural role but also via the oxidative decarboxylation of CoQ precursors. These findings fill a major gap in the knowledge of eukaryotic CoQ biosynthesis and shed light on the pathophysiology of human primary CoQ deficiency due to COQ4 mutations.

Background: Chronic kidney disease mineral bone disorder (CKD-MBD) is a condition characterized by alterations of calcium, phosphate, parathyroid hormone (PTH), and fibroblast growth factor 23 (FGF-23) metabolism that in turn promote bone disorders, vascular calcifications, and increase cardiovascular (CV) risk. Nephrologists' awareness of diagnostic, prognostic, and therapeutic tools to manage CKD-MBD plays a primary role in adequately preventing and managing this condition in clinical practice. Methods: A national survey (composed of 15 closed questions) was launched to inquire about the use of bone biomarkers in the management of CKD-MBD patients by nephrologists and to gain knowledge about the implementation of guideline recommendations in clinical practice. Results: One hundred and six Italian nephrologists participated in the survey for an overall response rate of about 10%. Nephrologists indicated that the laboratories of their hospitals were able to satisfy request of ionized calcium levels, 105 (99.1%) of both PTH and alkaline phosphatase (ALP), 100 (94.3%) of 25(OH)D, and 61 (57.5%) of 1.25(OH)2D; while most laboratories did not support the requests of biomarkers such as FGF-23 (intact: 88.7% and c-terminal: 93.4%), Klotho (95.3%; soluble form: 97.2%), tartrate-resistant acid phosphatase 5b (TRAP-5b) (92.5%), C-terminal telopeptide (CTX) (71.7%), and pro-collagen type 1 N-terminal pro-peptide (P1NP) (88.7%). As interesting data regarding Italian nephrologists' behavior to start treatment of secondary hyperparathyroidism (sHPT), the majority of clinicians used KDOQI guidelines (n = 55, 51.9%). In contrast, only 40 nephrologists (37.7%) relied on KDIGO guidelines, which recommended referring to values of PTH between two and nine times the upper limit of the normal range. Conclusion: Results point out a marked heterogeneity in the management of CKD-MBD by clinicians as well as a suboptimal implementation of guidelines in Italian clinical practice.

RESUMO
We report a newborn patient with trichothiodystrophy-3 (TTD3) caused by a novel homozygous variant in the GTF2H5 gene. His severe phenotype included congenital ichthyosis, complex posterior cranial fossa anomaly, life-threatening infections, bilateral cryptorchidism, and, notably, a complex cardiac malformation, which is unprecedented in TTD3 patients.

Background: Efficacy and safety of onasemnogene abeparvovec (OA) for Spinal Muscular Atrophy infants under 7 months and <8.5 kg has been reported in clinical trials. This study examines efficacy and safety predictors in a wide age (22 days-72 months) and weight (3.2-17 kg) range, also including patients previously treated with other drugs. Methods: 46 patients were treated for 12 months between January 2020 and March 2022. Safety profile was also available for another 21 patients with at least 6 month follow-up after OA infusion. 19/67 were treatment naïve when treated with OA. Motor function was measured with the CHOP-INTEND. Findings: CHOP-INTEND changes varied among age groups. Baseline score and age at OA treatment best predicted changes. A mixed model post-hoc analysis showed that in patients treated before the age of 24 months the CHOP-INTEND changes were already significant 3 months after OA while in those treated after the age of 24 months the difference was only significant 12 months after OA. Adverse events occurred in 51/67. The risk for elevated transaminases serum levels was higher in older patients. This was also true for weight and for pre-treatment with nusinersen when analysed individually. A binomial negative regression analysis showed that only age at OA treatment had a significant effect on the risk of elevated transaminases. Interpretation: Our paper describes OA 12-month follow-up showing efficacy across various age and weight groups not targeted by clinical trials. The study identifies prognostic factors for safety and efficacy in treatment selection. Funding: None.
RESUMO
BACKGROUND: There has been a growing interest in studying the value of physical exercise in children with disabilities or chronic health conditions because of evidence of improvement in quality of life, social acceptance, and physical functioning. However, only scant evidence exists for routine sports activities in children requiring pediatric palliative care (PPC), and in most cases, such evidence has been collected in oncological patients. The Pediatric Hospice of Padua is the referral center for PPC in the Veneto region (northern Italy). Starting from the experience of this PPC center, this pilot study aims to describe the personal experience of children and young people who practice physical activity and their caregivers' perspectives, focusing particularly on the emotional and social impact of exercise and sports practice. METHODS: Patients involved in at least one regular and structured sports activity were included in the pilot analysis. Two different ICF-CY (International Classification of Functioning, Disability and Health-Children and Youth Version) scales ("Body Function" and "Activity and Participation") were filled out to assess the children's global functional competence. Two online ad hoc questionnaires were created and administered to children, when able to respond, and caregivers. RESULTS: A total of 9% of patients reported being involved in a sports activity. All children who played sports did not have indications of cognitive retardation. The most practiced sport was swimming. The use of standardized methods such as ICF-CY shown that severe motor impairments do not limit sports accessibility. Questionnaires result suggest that sports are a positive experience for both children needing PPC and their parents. Children encourage other children to do sports and can find the positive side even in difficulties. CONCLUSION: Since PPC is encouraged as early as the diagnosis of incurable pathologies, the inclusion of sports activities in the context of a PPC plan should be considered from the perspective of improving quality of life.

BACKGROUND: We report the 4-year follow-up in type I patients treated with nusinersen and the changes in motor, respiratory and bulbar function in relation to subtype, age and SMN2 copy number. METHODS: The study included SMA 1 patients with at least one assessment after 12, 24 and 48 months from the first dose of nusinersen. The assessments used were Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) and the Hammersmith Infant Neurological Examination (HINE-II). RESULTS: Forty-eight patients, with ages ranging from 7 days to 12 years (mean 3.3 years, SD 3.6 years) were included in the study. The CHOP INTEND and HINE-II scores significantly increased between baseline and 48 months (p < 0.001). When age at starting treatment subgroups (<210 days, <2 years, 2-4 years, 5-11 years, ≥12 years) were considered, the CHOP INTEND increased significantly in patients younger than 4 years at treatment, while the HINE-2 increased significantly in patients younger than 2 years at treatment. In a mixed-model analysis, age, nutritional and respiratory status were predictive of changes on both scales while SMN2 copy number and decimal classification were not. CONCLUSIONS: Our results confirm the safety profile previously reported and support the durability of the efficacy of nusinersen at 4 years with an overall stability or mild improvement and no evidence of deterioration over a long period of time.

OBJECTIVE: Spinal muscular atrophy (SMA) is a neurodegenerative disorder caused by mutations in the SMN1 gene. The aim of this study was to assess the prevalence of SMA and treatment prescription in Italy. METHODS: An online survey was distributed to 36 centers identified by the Italian government as referral centers for SMA. Data on the number of patients with SMA subdivided according to age, type, SMN2 copy number, and treatment were collected. RESULTS: One thousand two hundred fifty-five patients with SMA are currently followed in the Italian centers with an estimated prevalence of 2.12/100,000. Of the 1,255, 284 were type I, 470 type II, 467 type III, and 15 type IV with estimated prevalence of 0.48, 0.79, 0.79 and 0.02/100,000, respectively. Three patients with SMA 0 and 16 presymptomatic patients were also included. Approximately 85% were receiving one of the available treatments. The percentage of treated patients decreased with decreasing severity (SMA I: 95.77%, SMA II: 85.11%, SMA III: 79.01%). DISCUSSION: The results provide for the first time an estimate of the prevalence of SMA at the national level and the current distribution of patients treated with the available therapeutical options. These data provide a baseline to assess future changes in relation to the evolving therapeutical scenario.

Nusinersen is the first oligonucleotide-based drug that is approved for the treatment of spinal muscular atrophy. In January 2020, the WHO declared COVID-19 a pandemic and nusinersen-provider centers had to postpone planned infusions for some children along with other related interventions. Considering the important contribution that the intrathecal infusions and other support activities could have on the quality of life of spinal muscular atrophy patients and their families, this emergency could have a relevant impact on the course of the pathology. The present work aims to assess the clinical and social issues that arise for spinal muscular atrophy children in care at the referral pediatric palliative care Centre of Padua (Veneto) from a delay in nusinersen infusions, resulting from the contingent COVID-19 restrictions. This evaluation has been carried out in both the short and long term after the first lockdown period and can be considered as a "proxy" of a situation of a possible delay in administration or management of infusions, due to other different causes.
RESUMO
BACKGROUND: Spinal muscular atrophy (SMA) is a neuromuscular disorder characterized by muscle atrophy and weakness. SMA type 1 (SMA1) is the most severe form: affected infants are unable to sit unaided; SMA type 2 (SMA2) children can sit, but are not able to walk independently. The Standards of Care has improved quality of life and the increasing availability of disease-modifying treatments is progressively changing the natural history; so, the clinical assessment of nutritional status has become even more crucial. Aims of this multicenter study were to present the growth pattern of treatment-naïve SMA1 and SMA2, and to compare it with the general growth standards. RESULTS: Body Weight (BW, kg) and Supine Length (SL, cm) were collected using a published standardized procedure. SMA-specific growth percentiles curves were developed and compared to the WHO reference data. We recruited 133 SMA1 and 82 SMA2 (48.8% females). Mean ages were 0.6 (0.4-1.6) and 4.1 (2.1-6.7) years, respectively. We present here a set of disease-specific percentiles curves of BW, SL, and BMI-for-age for girls and boys with SMA1 and SMA2. These curves show that BW is significantly lower in SMA than healthy peers, while SL is more variable. BMI is also typically lower in both sexes and at all ages. CONCLUSIONS: These data on treatment-naïve patients point toward a better understanding of growth in SMA and could be useful to improve the clinical management and to assess the efficacy of the available and forthcoming therapies not only on motor function, but also on growth.

BACKGROUND: Body composition assessment is paramount for spinal muscular atrophy type I (SMA I) patients, as weight and BMI have proven to be misleading for these patients. Despite its importance, no disease-specific field method is currently available, and the assessment of body composition of SMA I patients requires reference methods available only in specialized settings. OBJECTIVE: To develop predictive fat mass equations for SMA I children based on simple measurements, and compare existing equations to the new disease-specific equations. DESIGN: Demographic, clinical and anthropometric data were examined as potential predictors of the best candidate response variable and non-linear relations were taken into account by transforming continuous predictors with restricted cubic splines. Alternative models were fitted including all the dimensions revealed by cluster analysis of the predictors. The best models were then internally validated, quantifying optimism of the obtained performance measures. The contribution of nusinersen treatment to the unexplained variability of the final models was also tested. RESULTS: A total of 153 SMA I patients were included in the study, as part of a longitudinal observational study in SMA children conducted at the International Center for the Assessment of Nutritional Status (ICANS), University of Milan. The sample equally represented both sexes (56% females) and a wide age range (from 3 months to 12 years, median 1.2 years). Four alternative models performed equally in predicting fat mass fraction (fat mass/body weight). The most convenient was selected and further presented. The selected model uses as predictors sex, age, calf circumference and the sum of triceps, suprailiac and calf skinfold thicknesses. The model showed high predictive ability (optimism corrected coefficient of determination, R2 = 0.72) and internal validation indicated little optimism both in performance measures and model calibration. The addition of nusinersen as a predictor variable did not improve the prediction. The disease-specific equation was more accurate than the available fat mass equations. CONCLUSIONS: The developed prediction model allows the assessment of body composition in SMA I children with simple and widely available measures and with reasonable accuracy.

BACKGROUND: We report the clinical outcomes observed in our patients with SMA type 1 or 2 receiving nusinersen, and we comment on the ethical implications of this treatment, in line with our results and those reported by Audic et al. in their analysis published in the Orphanet Journal of Rare Diseases. METHODS: We analyzed records of all children with a genetically diagnosed SMA and clinically confirmed diagnosis of SMA Type 1 or 2 to whom nusinersen was offered. Follow-up lasted 30 months. RESULTS: Among the 17 children with SMA type 1, 6 interrupted treatment with nusinersen due to adverse events or lack of efficacy. Of the remaining 11 patients, 9 are responding to therapy, though multidisciplinary complex care is still required. All those children started nusinersen at a very early age. Eighteen patients with SMA type 2 received nusinersen; five required treatment interruption. The other 13 patients are still on nusinersen therapy, and 6 are responders. Among the seven non-responders, only two met the inclusion criteria of the pivotal trial. CONCLUSIONS: Our analysis further supports the findings reported in the study by Audic et al. We believe that a wider use of nusinersen in clinical practice would require a comprehensive assessment of its actual benefits weighed against the discomfort caused to patients, as well as the identification of the patients who may obtain the best benefits from this treatment.

The main consequence of the COVID-19 pandemic has been to increase the distance between patients and their doctors and to limit the opportunities to compare experiences and clinical cases in the medical community. Based on this, we adopted a strategy to create networks with the ambition to break down these distances and to unify the process of care and management. Here we report the results and perspectives of our efforts and studies. A summary of the presentations on the topic, held during the webinars organized for macro-areas by the Italian Association of Myology with the aim of raising awareness among "non-expert doctors" who deal with neuromuscular disorders in the era of COVID-19 was collected and here reported. Although the macro-areas responded in different way to the problems of neuromuscular patients in the era of COVID-19, they all have tried to create a network between doctors and opportunity for education and information, with the secondary outcome to have shared process of care and management. Telemedicine, virtual meetings and the strengthening of national and international networks, through research projects, were the nodal and common points. Due to their complexity, neuromuscular diseases had already taught clinicians the importance of multidisciplinary confrontation. COVID-19 has further strengthened the need to create links between clinicians and experts, even of different nationalities, in order to guarantee to patients the best possible care, but above all, access and continuity of care even in critical periods. Adequate answers have been given to these problems, though there is still a lot to improve.

AIM: In complex congenital heart diseases (CHD), patients may remain affected by significant morbidity and mortality after surgery. We analysed the end-of-life (EoL) care in children with severe CHD who died in our institution and investigated perspectives of parents and health-care professionals (HCPs). METHODS: Medical records of all children (age < 18 years old) affected by a severe CHD who died in a tertiary cardiac care centre were reviewed. Subsequently, a cross-sectional questionnaire-based study of parents and HCPs of children involved in the study was designed. RESULTS: In total, 30 children died (median age: 45 days; range: 15 days to 3.4 years). Of them, 97% (31/32) died in an intensive care unit setting and were intubated and sedated at EoL. A total of 77% (23/30) died without parents being present at bedside. Eighteen families and 10 HCPs were interviewed. For 61% of the parents (11/18) and 70% of the clinicians (7/10), the goal of therapy at the EoL was 'to lessen your child's suffering as much as possible'. Overall, 44% of parents (8/18) and 50% of HCPs recognised that their child had no chance of survival 'a few days before the child died'. CONCLUSIONS: We believe that these data suggest an unconscious reluctance to change goals of care in EoL, shifting from intensive care to comfort and quality of life.
