RESUMO

Background: PalliPed is the first Italian nationwide project aimed at describing the characteristics of patients accessing specialized pediatric palliative care (PPC) and their families, in the main care settings (hospice, home care, and hospital). The project's secondary aim is to assess the extent and quality of regional PPC networks/facilities and the number of dedicated resources. In this article, we present the results of the first part of the project. Methods: All Italian PPC centers/facilities were invited to participate in the project. Children and young adults in the care of the specialized PPC networks/structures as of 24 October, 2022, including prenatal care, were involved. Children's eligibility for specialized PPC was assessed according to the Assessment Form for Complex Clinical Needs in Pediatrics (ACCAPED Scale) and after a multidisciplinary assessment by the healthcare team. Data were collected through an online survey. Results: A total of 867 patients were described. The lack of adequate specialized PPC service emerged, according to the available estimate of specialized PPC needs, as well as the need for improved referral to PPC by pediatricians or territorial services, particularly for infants and oncological patients. More family support measures also seem necessary, particularly for the mothers. Healthcare providers' communication skills should be improved to ensure greater involvement of patients and families in care decisions. Conclusions: This analysis represents the first step toward defining a constantly updated database for the census and monitoring of specialized PPC activities at the national level. This research model can be extended to other realities in different countries, allowing comparison of different care models.

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.

RESUMO

OBJECTIVE: Sleep problems constitute a common and heterogeneous complaint in pediatric palliative care (PPC), where they often contribute to disease morbidity and cause additional distress to children and adolescents and their families already facing the burden of life-threatening and life-limiting conditions. Despite the significant impact of sleep problems, clinical evidence is lacking. The application of general pediatric sleep recommendations appears insufficient to address the unique challenges of the PPC dimension in terms of disease variability, duration, comorbidities, complexity of needs, and particular features of sleep problems related to hospice care. Therefore, we initiated an international project aimed at establishing a multidisciplinary consensus. METHODS: A two-round Delphi approach was adopted to develop recommendations in the areas of Definition, Assessment/Monitoring, and Treatment. After selecting a panel of 72 worldwide experts, consensus (defined as ≥75% agreement) was reached through an online survey. RESULTS: At the end of the two voting sessions, we obtained 53 consensus recommendations based on expert opinion on sleep problems in PPC. CONCLUSIONS: This study addresses the need to personalize sleep medicine's approach to the palliative care setting and its peculiarities. It provides the first international consensus on sleep problems in PPC and highlight the urgent need for global guidance to improve sleep-related distress in this vulnerable population and their caregivers. Our findings represent a crucial milestone that will hopefully enable the development of guidelines in the near future.

RESUMO

BACKGROUND: Accurate estimation of the specialized pediatric palliative care (PPC) burden and the definition of the extent and quality of PPC service in Italy represent urgent needs to enable the proper allocation of PPC resources and the definition of prevention and educational plans. The PalliPed project aimed to provide the first comprehensive assessment of the characteristics of Italian patients requiring PPC, the quality and extent of regional PPC networks/facilities, and the number of dedicated resources. In this paper, we present the results of the second part of the project, regarding the implementation and quality of PPC services in Italy. METHODS: The PalliPed study had an observational cross-sectional design. All Italian specialized PPC centers/facilities were invited to participate in the project and complete a survey on the characteristics of PPC centers/facilities in different care settings, reporting data as of 24 October 2022. Data were collected online. RESULTS: 19 PPC specialized centers/facilities from 12 Italian regions and two autonomous provinces responded to the survey. Among them, 11 are regional referral centers. Seven Italian regions out of 20 reported no PPC centers/facilities, mainly in central-southern Italy. Less than half (45%) of the regional referral centers cover the entire regional territory, and three offer 24/7 service. Ten centers have a dedicated team. Half of the eight non-referral centers offer 24/7 service and have a dedicated team. A total of 1,092 patients were reported by 18 centers as of 24 October 2022. Over the years, an increasing number of patients has been reported, rising from 1,202 (2019) to 1,544 (2021). The dedicated staff is inadequate, and most healthcare providers are not recognized at an institutional level. A shortage of 'young' staff and a lack of specific training was reported, particularly among nurses (77% had no training in PPC). CONCLUSIONS: The results obtained show how training, information, and research interventions are still necessary for the reorganization of the available resources and definition of proper strategies to respond dynamically to the new emerging needs of these populations. At the same time, our study represents a first step in defining a national registry of PPC models, useful for monitoring evolutions, and critical issues and planning any new or corrective strategy.

RESUMO

AIM: Given the multifaceted nature of paediatric palliative care (PPC), integrative medicine and mind-body therapies, in particular, are increasingly used in this setting. However, to our knowledge, their use in PPC has never been specifically reviewed. Therefore, this work aims to provide a comprehensive overview of the application and possible beneficial effects of mind-body therapies in the PPC setting. METHODS: Papers about the use of meditation and mindfulness, biofeedback, hypnosis, yoga, tai chi and qi gong, imagery, creative outlets, and art therapy in PPC were identified by browsing PubMed and CINHAL. RESULTS: We found that the harmless nature of mind-body therapies has been extensively described, and available studies consistently show some benefits on the anxiety, stress, and quality of life of parents/caregivers and healthcare providers. However, well-grounded and robust evidence does not fully support the efficacy of mind-body therapies, especially in patients. CONCLUSION: Considering the peculiarity of the PPC setting, we suggest that mind-body therapies should be further considered and properly investigated through larger controlled studies and according to the different populations of PPC children, as well as for parents, caregivers, and healthcare professionals.

RESUMO

The proper assessment of needs and outcomes in pediatric palliative care (PPC) is imperativeto ensure the best possible service to patients and families. However, given the multidimensionalnature of PPC, the low number of patients in this setting, the heterogeneity of diseases, the presenceof cognitive impairment in many patients, and the physiological development of children, outcomescan be complex and difficult to measure. Consequently, in this context, the use of standardizedand validated tools to assess the needs of children and families, to assess symptom severity, andto estimate the quality of PPC service represent a current need. Even if efforts have been made tostandardize approaches and tools for palliative care in adults, to our knowledge, a similar comprehensiveassessment of PPC has not yet been conducted to date. This narrative review provides anoverview and discusses the evaluation of tools currently applied in PPC, with an educational intentfor healthcare providers. We found that several instruments are available to assess different dimensionsof PPC. We proposed a classification into eligibility tools, patient and family needs assessmenttools, and care assessment tools. At present, two main eligibility tools exist, the PaPaS Scale and theACCAPED Scale questionnaire. Most of the tools for patient and family needs assessment have notbeen specifically validated in the PPC setting, and many may be more readily applied in researchsettings rather than in daily practice. Similar considerations can be made for tools assessing QoL,while tools assessing PPC service quality seem to be easily applied. Efforts to develop new specifictools and validate existing ones are undoubtedly advocated. However, in the patient's best interest,PPC healthcare providers should start using available tools, regardless of their validation status.

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.

RESUMO

Establishing a common language that allows univocal and objective communication in describing wounds and their healing is of utmost importance in defining the diagnostic hypothesis and proper wound management. To measure the level of agreement on the description of wounds, an international study was performed among experts of different professional backgrounds on several common terms used to describe ulcerative lesions. A panel of 27 wound care experts anonymously completed a multiple-choice questionnaire on 100 images of 50 ulcerative lesions. The participants were asked to describe each image using a set of pre-defined terms. An expert data analyst interpreted the questionnaires to map the level of agreement on the used terminology. Our findings show a very low level of agreement among experts in using the proposed terminology to describe the wound bed, the wound edge, and the surrounding skin conditions. Efforts should be planned to find a consensus on the correct use of terminology for wound description. To this aim, partnership, consensus, and agreement with educators in medicine and nursing are necessary.

RESUMO

Background: Whether the etiology of underlying liver disease represents a prognostic factor in patients with hepatocellular carcinoma (HCC) treated with lenvatinib is still a matter of debate. This study investigates whether the viral etiology of HCC plays a prognostic role in overall survival (OS). Methods: Data derived from a multicenter series of 313 HCC patients treated with lenvatinib between 2019 and 2022 were analyzed. Actuarial survival estimates were computed using the Kaplan−Meier method and compared with the log-rank test. We performed an event-based counterfactual mediation analysis to estimate direct (chronic inflammation and immunosuppression), indirect (tobacco smoking, alcohol use, illicit drug abuse with injections), and the total effect of viral etiology on OS. Results were expressed as hazard ratio (HR) and 95% CI. Results: Median OS was 21 months (95% CI: 20−23) in the group with other etiologies and 15 months (14−16) in the group with viral etiology (p < 0.0001). The total effect of viral etiology was associated with OS (HR 2.76, 1.32−5.21), and it was mainly explained by the pure direct effect of viral etiology (HR 2.74, 1.15−4.45). By contrast, its total indirect effect was not associated with poorer survival (HR 1.05, 0.82−2.13). These results were confirmed when considering tobacco, alcohol consumption, or injection drug abuse as potential mediators. Median progression-free survival was 9 months (8−10) in patients with other etiologies and 6 months (5−7) in patients with viral etiology (p < 0.0001). No difference in terms of adverse event rate was observed between the two groups. Conclusions: Patients affected by HCC with nonviral etiology treated with lenvatinib exhibit longer survival than those with viral etiology. This finding may have relevance in the treatment decision-making process.

RESUMO

About 4 million children with an oncological disease worldwide require pediatric palliative care (PPC) due to the nature of their condition. PPC is not limited to end-of-life care; it is a general approach continuing over the entire disease trajectory, regardless of whether the patient receives any oncological treatment. This review addresses the value of integrating PPC in treating children with cancer, focusing on the basic principles of PPC and its application in pediatric oncology. Moreover, models for PPC implementation in oncology, end-of-life care, and advanced care planning are discussed.

RESUMO

CONTEXT: Since the publication of the IMPaCCT project in 2007, much effort has been made to develop new approaches to pediatric palliative care (PPC). Fifteen years later, it is time to redefine the standards in PPC. OBJECTIVES: An international group of experts in PPC has revised the standards in PPC through the GO-PPaCS project (Global Overview - PPC Standards). The goal was to update the PPC standards considering the specificity of different settings, resources, and emerging challenges. The present document is intended to reach all people directly or indirectly involved in PPC. METHODS: A literature review in MEDLINE was conducted to expand on the fundamental points and current standards on PPC and to cover an international setting. The literature search (updated on the 15th of April 2021) was carried out using different combinations of keywords and focusing on papers published in English over the past 5 years (2016-2020), but older articles were considered when relevant. The consensus on the fundamental points, standards of care and paper contents was reached by open discussion. RESULTS: Fundamental points were defined regarding the definition of PPC, eligibility criteria and the magnitude of the need for PPC, while standards were redefined for the following six areas: 1) clinical, developmental, psychological, social, ethical and spiritual needs; 2) end-of-life care; 3) care models and settings of care; 4) PPC in humanitarian emergencies; 5) care tools; and 6) education and training for healthcare providers. CONCLUSION: The present document, developed with the contribution of an international group of experts from different countries, experiences and models of care, provides fundamental points and standards for a wider implementation of PPC worldwide.

RESUMO

Frailty represents a state of vulnerability to multiple internal physiologic factors, as well as external pressures, and has been associated with clinical outcomes. We aim to understand the impact of frailty on patients admitted with hepatocellular carcinoma (HCC) by using the validated Hospital Frailty Risk Score, which is implemented in several hospitals worldwide. We conducted a nation-wide retrospective cohort study to determine the effect of frailty on the risk of in-patient mortality, hepatic encephalopathy, length of stay and cost. Frailty was associated with a 4.5-fold increased risk of mortality and a 2.3-fold increased risk of hepatic encephalopathy. Adjusted Cox regression showed that frailty was correlated with increased risk of in-patient mortality (hazard ratio: 2.3, 95% CI 1.9-2.8, p < 0.001). Frail HCC patients had longer hospital stay (median 5 days) vs. non-frail HCC patients (median 3 days). Additionally, frail patients had higher total costs of hospitalization ($40,875) compared with non-frail patients ($31,667). Frailty is an independent predictor of hepatic encephalopathy and in-patient mortality. Frailty is a surrogate marker of hospital length of stay and cost.

RESUMO

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: One of the main challenges for paediatric palliative care (PPC) is the management of concomitant, different and severe symptoms that frequently affect the quality of life of PPC patients and are often refractory to commonly used pharmacological treatments. Consequently, many efforts are still needed to find the best therapeutic options to handle these refractory conditions. Since the first synthesis of ketamine in the 1960s, its pharmacokinetic and pharmacodynamic properties have been largely investigated and its potential wide range of clinical applications has become clear. However, this molecule still receives poor attention in some areas, including in children and PPC. This narrative review analyses the use of ketamine in children and the potential extension of its applications in PPC in order to provide new options for treatment in the PPC setting. METHODS: Scientific papers published before October 2020 on MEDLINE, EMBASE and the Cochrane Library were considered. The cited references of the selected papers and the authors' personal collections of literature were reviewed. The terms "palliative care", "ketamine", "neuropathic pain", "procedural pain", "status epilepticus", "refractory pain" and "child", adding "age: birth-18 years" on a further filter were used for the search. DISCUSSION: The use of ketamine in PPC should be more widely considered due to its overall favourable safety profile and its efficacy, which are supported by an increasing number of studies, although in settings different from PPC and of mixed quality. Ketamine should be proposed according to a case-by-case evaluation and the specific diagnosis and the dosage and route of administration should be tailored to the specific needs of patients. Furthermore, there is evidence to suggest that ketamine is safe and efficacious in acute pain. These findings can prompt further research on the use of ketamine for the treatment of acute pain in PPC. CONCLUSION: Ketamine could be a suitable option after the failure of conventional drugs in the treatment of different refractory conditions in PPC.

RESUMO

Although combination therapy is not recommended in patients with gastro-entero-pancreatic (GEP) neuroendocrine tumors (NETs), this strategy is widely used in clinical practice. This network meta-analysis of randomized trials evaluates targeted therapies and somatostatin analogues in GEP-advanced NETs, either alone or in combination, comparing the efficacy of different, single or combined treatment strategies in terms of progression-free survival (PFS). Interventions were grouped as analogs, everolimus, everolimus plus SSAs, sunitinib and placebo. In a secondary analysis, we also assessed the efficacy of individual-specific pharmacological treatments vs placebo or each other. From 83 studies identified, 8 randomized controlled trials were selected, with a total of 1849 patients with either functioning or non-functioning NETs. The analysis confirmed the superiority of all treatments over placebo (HR ranging from 0.34, 95% CI: 0.24-0.37 with the combination of everolimus plus SSAs to 0.42, 0.31-0.57 with the analogs; moderate quality of evidence). On ranking analysis, the combination of everolimus plus SSA (P score = 0.86) and then everolimus alone (P score = 0.65) ranked highest in increasing PFS. On comparative evaluation of different interventions, pasireotide (P score = 0.96) and everolimus + octreotide (P score = 0.82) ranked as the best pharmacological treatment options. Our findings support the use of combination therapy in the treatment of functioning and non-functioning GEP NETs. The role of pasireotide should be explored in selected subgroups of patients. Lastly, the combination of everolimus and octreotide appears promising and should be more widely considered in clinical practice.

RESUMO

INTRODUCTION: Patients in pediatric palliative care (PPC) live with multiple comorbidities which represent a risk factor for severe form of COVID-19. METHODS: This monocentric retrospective study was performed at the PPC Center of Padua (Italy). Testing methodology, prevention strategies and infection characteristics were documented and compared during the first and second peak of SARS-CoV-2 infection. RESULTS: Between April-June 2020 a population swab screening was performed and a strong reduction of the habitual family support was observed. Between November 2020-January 2021 swab testing was limited to specific cases and the support network for families was partially restored. Incidence of COVID-19 was low, resulting in 0.04% of total pediatic cases in the Veneto Region. No severe forms were observed. CONCLUSION: The use of adequate preventive measures by families and support networks associated with testing in specific contests is safe, cost effective and has a minor impact on caregiver's care load.

RESUMO

Astrogliosis has a unique reaction during spinal cord damage, with helpful or adverse impacts on recovery. There is consequently a pressing need for treatment to target activated astrocytes and their unsafe response after injury to ensure some preservative effect during the progressive damage. We specifically developed and characterized a functionalized nanogel-based nanovector in vitro and in vivo, demonstrating its selectivity towards astrocytes, and limited uptake by macrophages when functionalized with both NH2 and Cy5 groups. In vitro experiments showed that the internalization was mediated by a clathrin-dependent endocytic pathway. After internalization into the cytoplasm of astrocytes, nanogels undergo lysosomal degradation and release compounds with potential therapeutic efficacy.
