ABSTRACT

Introduction: The number of children requiring long-term invasive home ventilation (LTIHV) has increased worldwide in recent decades. The training of physicians caring for these children is crucial since they are at high risk for complications and adverse events. This study aimed to assess the efficacy of a comprehensive high-fidelity simulation-based training program for physicians caring for children on LTIHV. Methods: A multimodal training program for tracheostomy and ventilator management was prepared by ISPAT (IStanbul PAediatric Tracheostomy) team. Participants were subjected to theoretical and practical pre-tests which evaluated their knowledge levels and skills for care, follow-up, and treatment of children on LTIHV. Following the theoretical education and hands-on training session with a simulation model, theoretical and practical post-tests were performed. Results: Forty-three physicians from 7 tertiary pediatric clinics in Istanbul were enrolled in the training program. Seventy percent of them had never received standardized training programs about patients on home ventilation previously. The total number of correct answers from the participants significantly improved after the theoretical training (p < 0.001). The number of participants who performed the steps correctly also significantly increased following the hands-on training session (p < 0.001). All of the 43 participants who responded rated the course overall as good or excellent. Conclusion: The knowledge and skills of clinicians caring for children on LTIHV can be enhanced through a comprehensive training program consisting of theoretical training combined with hands-on training in a simulation laboratory.

ABSTRACT

BACKGROUND: Our aim was to identify acute kidney injury (AKI) and subacute kidney injury using both KDIGO criteria and urinary biomarkers in children with mild/moderate COVID-19. METHODS: This cross-sectional study included 71 children who were hospitalized with a diagnosis of COVID-19 from 3 centers in Istanbul and 75 healthy children. We used a combination of functional (serum creatinine) and damage (NGAL, KIM-1, and IL-18) markers for the definition of AKI and subclinical AKI. Clinical and laboratory features were evaluated as predictors of AKI and subclinical AKI. RESULTS: Patients had significantly higher levels of urinary biomarkers and urine albumin-creatinine ratio than healthy controls (p < 0.001). Twelve patients (16.9%) developed AKI based on KDIGO criteria, and 22 patients (31%) had subclinical AKI. AKI group had significantly higher values of neutrophil count on admission than both subclinical AKI and non-AKI groups (p < 0.05 for all). Neutrophil count was independently associated with the presence of AKI (p = 0.014). CONCLUSIONS: This study reveals that even children with a mild or moderate disease course are at risk for AKI. Association between neutrophil count and AKI may point out the role of inflammation in the development of AKI. IMPACT: The key message of our article is that not only children with severe disease but also children with mild or moderate disease have an increased risk for kidney injury due to COVID-19. Urinary biomarkers enable the diagnosis of a significant number of patients with subclinical AKI in patients without elevation in serum creatinine. Our findings reveal that patients with high neutrophil count may be more prone to develop AKI and should be followed up carefully. We conclude that even children with mild or moderate COVID-19 disease courses should be evaluated for AKI and subclinical AKI, which may improve patient outcomes.

ABSTRACT

Multisystem inflammatory syndrome in children (MIS-C) evolves in some pediatric patients following acute infection with SARS-CoV-2 by hitherto unknown mechanisms. Whereas acute-COVID-19 severity and outcomes were previously correlated with Notch4 expression on Tregs, here, we show that Tregs in MIS-C were destabilized through a Notch1-dependent mechanism. Genetic analysis revealed that patients with MIS-C had enrichment of rare deleterious variants affecting inflammation and autoimmunity pathways, including dominant-negative mutations in the Notch1 regulators NUMB and NUMBL leading to Notch1 upregulation. Notch1 signaling in Tregs induced CD22, leading to their destabilization in a mTORC1-dependent manner and to the promotion of systemic inflammation. These results identify a Notch1/CD22 signaling axis that disrupts Treg function in MIS-C and point to distinct immune checkpoints controlled by individual Treg Notch receptors that shape the inflammatory outcome in SARS-CoV-2 infection.

ABSTRACT

BACKGROUND: Respiratory involvement is the main factor predicting the prognosis of spinal muscular atrophy (SMA). Significant responses in motor functions have been demonstrated with nusinersen, but pulmonary outcomes are still varied. We aimed to explore the effects of nusinersen on the respiratory functions of patients with SMA. METHODS: Patients with SMA who were receiving regular nusinersen treatment in our tertiary care hospital were enrolled in this study. We evaluated the patients in terms of the necessity to ventilatory or nutritional support, presence of motor involvement and other comorbidities related with prognosis at three consecutive assessments. RESULTS: The study group consisted of 43 patients (18 type 1, 12 type 2, and 13 type 3) with SMA with a mean age of 27.8 months at diagnosis and 60.8 months at the beginning of nusinersen treatment. The respiratory function improvements were noted in six patients at third assessment. Early initiation of nusinersen was significantly correlated with reduced hospital admissions (P = 0.026). Nutritional support and weight gain were remarkable in the ventilatory-supported group. Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders scores were significantly higher in the non-tracheostomized group in patients with SMA type 1 (P < 0.005). CONCLUSIONS: We posit that nusinersen may change the natural prognosis of SMA and improve care of children with SMA. Following up children with SMA for longer periods under nusinersen may be beneficial for understanding the effects of treatment. Results of our study need to be supported by future long-term studies to reach a consensus on nusinersen, considering the overall genetic and environmental status as well as the cost-effectiveness of the treatment.

ABSTRACT

Multisystem inflammatory syndrome in children (MIS-C) evolves in some pediatric patients following acute infection with SARS-CoV-2 by hitherto unknown mechanisms. Whereas acute-COVID-19 severity and outcome were previously correlated with Notch4 expression on regulatory T (Treg) cells, here we show that the Treg cells in MIS-C are destabilized in association with increased Notch1 expression. Genetic analysis revealed that MIS-C patients were enriched in rare deleterious variant impacting inflammation and autoimmunity pathways, including dominant negative mutations in the Notch1 regulators NUMB and NUMBL. Notch1 signaling in Treg cells induced CD22, leading to their destabilization in an mTORC1 dependent manner and to the promotion of systemic inflammation. These results establish a Notch1-CD22 signaling axis that disrupts Treg cell function in MIS-C and point to distinct immune checkpoints controlled by individual Treg cell Notch receptors that shape the inflammatory outcome in SARS-CoV-2 infection.

ABSTRACT

Objectives:This study aimed to monitor the health and nutritional status of pediatric cystic fibrosis (CF) patients via telehealth services during the novel coronavirus disease 2019 (COVID-19). Additional aims were to determine the level of anxiety in the patients and their caregivers and to determine the COVID-19 transmission status among CF patients.Materials and Methods:The CF team supported the patients via remote contact. During telehealth services interviews, in addition to obtaining information about the patients' anthropometric measurements, health status, and CF-related complaints, the State-Trait Anxiety Inventory (STAI) was administered to the patients and controls. The Hospital Anxiety and Depression Scale (HAD) was administered to their caregivers.Results:The study included 144 pediatric CF patients (74 males and 70 females). Mean age of the patients was 8.9 years. In all, 42 (29.2%) of the patients were tested for COVID-19, of which 4 were positive. The mean STAI score was significantly lower in the patient group than in the control group (p < 0.001). The mean HAD anxiety score was significantly higher in the caregivers of the CF patients, compared to the caregivers of the controls (p = 0.005). In addition, the mean HAD depression score was significantly higher in the caregivers of the CF patients (p < 0.001).Conclusions:Telehealth is an innovative method for providing health care services while maintaining social distance and avoiding the risk of exposure and spread of COVID-19. Telehealth services reduce patient and parental anxiety and increase the level of confidence in managing CF-related complications.

ABSTRACT

Thyrotoxic patients may occasionally present with affective disorders. Here, we discuss a case of a 61-year-old woman with misidentification and persecutory delusions, olfactory hallucinations, and apathy associated with thyrotoxicosis. After definitive antithyroid and antipsychotic agent haloperidol treatments, the patient was released within 4 weeks. Thyrotoxic psychosis with apathy is a rare entity that can be misdiagnosed as affective psychosis. Haloperidol may be an alternative treatment in resolving psychotic features beside the treatment of hyperthyroid state.
