RESUMO
A retrospective observational study was conducted among healthcare workers (HCWs) in a tertiary paediatric hospital. The study covered the period before and after implementation of the vaccination programme and evaluated the incidence of new SARS-CoV-2 infections in both periods. Risk factors of the new SARS-CoV-2 infection and COVID-19 vaccine effectiveness was also assessed in a real-world setting. The overall incidence of SARS-CoV-2 infections among HCWs in the study period was 19.4% with a high proportion of asymptomatic individuals (45.1%). The incidence before vaccination was 16.6% and nurses had a higher risk of infection, while physicians had a reduced risk (OR 1.80, 95% CI 1.29-2.52; and OR 0.45, 95% CI 0.30-0.68). Within two months of implementation, the programme achieved a high (88.9%) vaccination coverage in our cohort, although some disparities in vaccination rates were observed. In particular, older individuals, physicians, those working in clinical settings, and those previously uninfected were more likely to be vaccinated. The overall incidence of SARS-CoV-2 infection after vaccination deployment was 6.4% (40.0% in unvaccinated individuals and 3.2% in individuals vaccinated with at least one dose). The estimated vaccine efficacy was high (95.0%) in fully vaccinated HCWs and similar to those observed previously in clinical trials and real-world settings.

In humans, 23 elements have been shown to have biological activity. The purpose of this study was to evaluate the concentrations of iron (Fe), zinc (Zn), sodium (Na), potassium (K), magnesium (Mg), phosphorus (P), and calcium (Ca) in the serum of patients diagnosed with lumbar degenerative stenosis when compared to the concentrations of those elements in the serum of healthy volunteers. The study group consisted of 60 patients who were diagnosed with degenerative stenosis of the lumbosacral spine and who qualified for hemilaminectomy. The control group included 60 healthy volunteers without degenerative spinal stenosis. The clinical specimens studied had sera collected from both groups. The quantitative analysis of the selected elements revealed statistically significant (p < 0.05) lower concentrations of Zn (740 ± 110 µg/L vs. 880 ± 160 µg/L) and Mg (22,091 ± 4256 µg/L vs. 24,100 ± 4210 µg/L) in the serum of the patients from the study group when compared to the controls. By contrast, K (16,230 µg/L ± 1210 µg/L vs. 13,210 µg/L ± 1060 µg/L) and Fe (141.87 µg/L ± 11.22 µg/L vs. 109.1 µg/L ± 26.43 µg/L) levels were significantly higher in the study group compared to the controls (p < 0.05). No statistically significant changes were detected in the concentrations of the assessed micronutrients and macronutrients in both sexes in either the study group, the control group, or those based on body mass index (p > 0.05). In the serum samples from the study group, the strongest correlations were noted between the concentrations. In the study group, we showed a significant relationship between the levels of Fe/Zn (r = 0.41), Fe/Na (r = 0.41), Fe/P (r = 0.55), Zn/P (r = 0.68), Zn/K (r = 0.48), Zn/Ca (r = 0.94), Mg/Ca (r = 0.79), and Na/K (r = 0.67). We showed that only Mg concentration varied statistically significantly with the severity of pain (p < 0.05). These findings suggest that the assessment of Fe, Zn, Mg, and K concentrations can be helpful in predicting the onset of degenerative changes in the spine.
RESUMO
The COrona VIrus Disease 2019 (COVID-19) pandemic is posing an unprecedented challenge to healthcare systems around the globe. Europe has been struggling for 1 year now, and despite some encouraging progress (above all, the beginning of vaccination), the second wave is ongoing. Even though children are less affected than adults, the COVID-19 pandemic-and in particular the measures to counter it-is having a considerable impact on the paediatric healthcare setting. It is, therefore, the duty of paediatric teams in Europe to prepare for the challenges ahead. We wish to contribute to this necessary preparedness in two ways: firstly, by assessing the direct and indirect impact of the pandemic on children and on the paediatric setting; secondly, and more importantly, by identifying the various responsibilities of paediatric healthcare professionals, in light of established ethical principles. Only abiding by these responsibilities will it be possible to ensure that ill children and their families are properly supported even in these difficult times and to grant that decisions about children's healthcare remain morally justified and lawful. What is Known: ⢠The COVID-19 outbreak is posing an unprecedented challenge to healthcare systems around the globe ⢠Despite the children are less affected than adults, the COVID-19 pandemic is having a huge impact also on paediatric setting What is New: ⢠The COVID-19 pandemic lays out specific responsibilities of paediatric professionals towards our pa-tients, society and ourselves ⢠The paediatric teams in Europe should assess the direct and indirect impact of the pandemic on the chil-dren and on the paediatric settings, ensuring consistency between centres and across regions in Europe.

BACKGROUND: Brain death/death by neurologic criteria (BD/DNC) guidelines are routinely analyzed, compared and updated in the majority of countries and are later implemented as national criteria. At the same time, extensive works have been conducted in order to unify clinical procedures and to validate and implement new technologies into a panel of ancillary tests. Recently evaluated computed tomography angiography and computed tomography perfusion (CTA/CTP) seem to be superior to traditionally used digital subtraction angiography (DSA), transcranial Doppler (TCD) and cerebral perfusion scintigraphy for diagnosis of cerebral circulatory arrest (CCA). In this narrative review, we would like to demonstrate scientific evidence supporting the implementation of CTA/CTP in Polish guidelines for BD/DNC diagnosis. Research and implementation process: In the first of our base studies concerning the potential usefulness of CTA/CTP for the confirmation of CCA during BD/DNC diagnosis procedures, we showed a sensitivity of 96.3% of CTA in a group of 82 patients. CTA was validated against DSA in this report. In the second study, CTA showed a sensitivity of 86% and CTP showed a sensitivity of 100% in a group of 50 patients. In this study, CTA and CTP were validated against clinical diagnosis of BD/DNC supported by TCD. Additionally, we propose our CCA criteria for CTP test, which are based on ascertainment of cerebral blood flow (CBF) < 10 mL/100 g/min and cerebral blood volume < 1 mL/100 g in regions of interest (ROIs) localized in all brain regions. Based on our research results, CTA/CTP methods were implemented in Polish BD/DNC criteria. To our knowledge, CTP was implemented for the first time in national guidelines. CONCLUSIONS: CTA and CTP-derived CTA might be in future the tests of choice for CCA diagnosis, proper and/or Doppler pretest might significantly increase sensitivity of CTA in CCA diagnosis procedures. Whole brain CTP might be decisive in some cases of inconclusive CTA. Implementation of CTA/CTP in the Polish BD/DNC diagnosis guidelines does not show any major obstacles. We believe that in next edition of "The World Brain Death Project" CTA and CTP will be recommended as ancillary tests of choice for CCA confirmation during BD/DNC diagnosis procedures.
RESUMO
We would like to invite paediatric intensive care units (PICU) to join our multi-center trial concerning patient population < 12 y/o and aiming at: ⢠validation of computed tomography angiography (CTA)/computed tomography perfusion (CTP) tests for brain death/death by neurological criteria (BD/DNC) diagnosis procedures, ⢠validation of duplex Doppler insonation of extracranial segments of the internal cerebral arteries and the vertebral arteries for choosing an optimal time for CTA/CTP testing.

Data on the prevalence of the SARS-CoV-2 antibody in healthcare workers (HCWs) is scarce, especially in pediatric settings. The purpose of this study was to evaluate SARS-CoV-2 IgG-positivity among HCWs of a tertiary pediatric hospital. In addition, follow-up of the serological response in the subgroup of seropositive HCWs was analysed, to gain some insight on the persistence of IgG antibodies to SARS-CoV-2. We performed a retrospective analysis of voluntary SARS-CoV-2 IgG testing, which was made available free of charge to HCWs of the Children's Memorial Health Institute in Warsaw (Poland). Plasma samples were collected between July 1 and August 9, 2020, and tested using the Abbott SARS-CoV-2 IgG assay. Of 2,282 eligible participants, 1,879 (82.3%) HCWs volunteered to undergo testing. Sixteen HCWs tested positive for SARS-CoV-2 IgG, corresponding to a seroprevalence of 0.85%. Among seropositive HCWs, three HCWs had confirmed COVID-19. Nine (56.3%) of the seropositive HCWs reported neither symptoms nor unprotected contact with confirmed SARS-CoV-2 cases in the previous months. A decline in the IgG index was observed at a median time of 86.5 days (range:84â128 days) after symptom onset or RT-PCR testing. Further studies are necessary to elucidate the duration of persistence of anti-SARS-CoV-2 antibodies, as well as the correlation between seropositivity and protective immunity against reinfection. Regardless of the persistence of antibodies and their protective properties, such low prevalence indicates that this population is vulnerable to a second wave of the COVID-19 pandemic.

In Poland, guidelines for the management of ineffective treatment of children in neonatal and paediatric departments developed by the Polish Neonatal Society and the Polish Paediatric Society, have been published. The specific problems of futile therapy in paediatric anaesthesiology and intensive care units should be defined and solved separately. For this purpose, the guidelines presented below were prepared. They present the principles for managing children for whom therapeutic options available in paedia-tric anaesthesiology and intensive care units have been exhausted and ineffectiveness of maintaining organ functions, i.e. futile therapy, has been suspected. The decision to withdraw futile therapy of a child is undoubtedly one of the most difficult for both doctors and parents, and for this reason, it should be made collectively, respecting the dignity of the child and his/her parents or legal representatives, and continuing the management aimed at relieving the child's pain and suffering, as well as minimising anxiety and fear. Due to the small amount of reliable evidence-based data, the guidelines constitute the consensus of the Group of Experts and are dedicated to minor patients treated in paediatric anaesthesiology and intensive care units.

BACKGROUND: Congenital Central Hypoventilation Syndrome (CCHS) is a rare condition characterized by an alveolar hypoventilation due to a deficient autonomic central control of ventilation and a global autonomic dysfunction. Paired-like homeobox 2B (PHOX2B) mutations are found in most of the patients with CCHS. In recent years, the condition has evolved from a life-threatening neonatal onset disorder to include broader and milder clinical presentations, affecting children, adults and families. Genes other than PHOX2B have been found responsible for CCHS in rare cases and there are as yet other unknown genes that may account for the disease. At present, management relies on lifelong ventilatory support and close follow up of dysautonomic progression. BODY: This paper provides a state-of-the-art comprehensive description of CCHS and of the components of diagnostic evaluation and multi-disciplinary management, as well as considerations for future research. CONCLUSION: Awareness and knowledge of the diagnosis and management of this rare disease should be brought to a large health community including adult physicians and health carers.

Children form a specific group of patients, as there are significant differences between children and adults in both anatomy and physiology. Difficult airway may be unanticipated or anticipated. Difficulties encountered during intubation may cause hypoxia, hypoxic brain injury and, in extreme situations, may result in the patient's death. There are few paediatric difficult-airway guidelines available in the current literature, and some of these have significant limitations. This position paper, intended for unanticipated difficult airway, was elaborated by the panel of specialists representing the Polish Society of Anaesthesiology and Intensive Care as well as the Polish Neonatal Society. It covers both elective intubation and emergency situations in children in all age groups. An integral part of the paper is an algorithm. The paper describes in detail all stages of the algorithm considering some modification in specific age groups, i.e. neonates.

Tracheal intubation may be defined as an artificial airway established in order to provide mechanical ventilation of the lungs during surgical procedures under general anaesthesia, treatment in an intensive care unit, as well as in emergency situations. Difficulties encountered during intubation may cause hypoxia, hypoxic brain injury and, in extreme situations, may result in the patient's death. There may be unanticipated and anticipated difficult airway. Children form a specific group of patients as there are significant differences in both anatomy and physiology. There are some limitations in equipment used for the airway management in children. There are only few paediatric difficult airway guidelines available, some of which have significant limitations. The presented algorithm was created by a group of specialists who represent the Polish Society of Anaesthesiology and Intensive Therapy, as well as the Polish Neonatology Society. This algorithm is intended for the unanticipated difficult airway in children and can be used in all age groups. It covers both elective intubation, as well as rescue techniques. A guide forms an integral part of the algorithm. It describes in detail all stages of the algorithm considering some modifications in a specific age group, e.g. neonates. The main aim of Stage I is to optimise conditions for face mask ventilation, laryngoscopy and intubation. Stage IIA focuses on maximising the chances of successful intubation when face mask ventilation is possible. Stage IIB outlines actions aimed at improving face mask ventilation. Stage IIIA describes the use of a SAD (Supraglottic Airway Device) during effective face mask ventilation or in a CICV (Cannot Intubate, Cannot Ventilate) situation. Stage IIIB outlines intubation through a SAD. Stage IV describes rescue techniques and outlines possible options of either proceeding with surgery or postponing it, depending on clinical situation.

Biotin-thiamine-responsive basal ganglia disease is a severe form of a rare neurogenetic disorder caused by pathogenic molecular variants in the thiamine transporter gene. Nowadays, a potentially effective treatment is known, therefore the early diagnosis is mandatory. The aim of the paper was to assess the contribution of neuropathological and magnetic resonance imaging (MRI) studies to a proper diagnosis. We present the brain study of two Polish patients with SLC19A3 mutations, including (1) an infant with an intriguing "walnut" appearance of the brain autopsied many years before the discovery of the SLC19A3 defect, and (2) a one-year-old patient with clinical features of Leigh syndrome. In patient 2, biotin/thiamine responsiveness was not tested at the time of diagnosis and causal treatment started with one-year delay. The central nervous system lesions found in the patients displayed almost clearly a specific pattern for SLC19A3 defect, as previously proposed in diagnostic criteria. Our study presents a detailed description of neuropathological and MRI findings of both patients. We confirm that the autopsy and/or MRI of the brain is sufficient to qualify a patient with an unknown neuropathological disorder directly for SLC19A3 mutations testing and a prompt trial of specific treatment. .

ROHHAD syndrome (Rapid-onset Obesity with Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation) is characterized by rapid-onset obesity in young children, hypoventilation, and hypothalamic and autonomic dysfunction. The exact aetiology of the disease remains unknown, and the number of reported cases seems to be underestimated. We present the case of a nine-year-old male patient suspected of ROHHAD due to weight gain since early childhood, decreased height velocity, hypoventilation, hypodipsia, excessive perspiration, and pyrexial episodes. The presented symptoms, and laboratory and imaging findings met the criteria of ROHHAD syndrome. ROHHAD should be considered in differential diagnosis for obesity in children. Early identification of the disease prevents potential complications specific for the syndrome, in particular a life-threatening cardio-pulmonary arrest. Patients with ROHHAD require regular follow-up by a multidisciplinary team.

Providing nutritional therapy via the gastrointestinal tract in patients in paediatric intensive care units (PICUs) is an effective method for delivering energy and other nutrients. In the event of contraindications to using this method, it is necessary to commence parenteral nutrition. In the present study, methods for nutritional treatments in critically ill children are presented, depending on the clinical situation.

UNLABELLED: Rituximab (anti-B CD20 ab.) in recently widely used in renal transplantation. CASE HISTORY: A 10-yr-old patient with end-stage renal failure due to multidrug-resistant NS was transplanted with renal graft from deceased donor and presented immediate recurrence of NS. PF was started on day 3 and patient received MP pulses, however with no effect. Rituximab (4 × 375 mg/m(2)) was administered. Chest radiographs taken at that time were normal. Partial remission was achieved and the patient was discharged in good condition. Sequential recurrence appeared two wk afterward. Twelve sessions of PF were performed and six pulses of MP were given, effecting a partial remission. Three months after the last dose of rituximab, patient was admitted with increasing respiratory failure, requiring mechanical ventilation. Infectious background, including CMV, BKV, mycoplasma, and pneumocystis, was not confirmed. The patient was treated with MP pulses, IVIG, and a variety of antibiotics. Ground-glass opacity was confirmed on lung CT images. Respiratory failure worsened, despite aggressive ventilation and patient passed away after three wk at ICU. A destruction of alveolar epithelium and extended pulmonary fibrosis was confirmed in the autopsy report. The case represents a fatal RALI.

BACKGROUND: Home mechanical ventilation (HMV) is a routine method of treatment for patients with chronic ventilatory failure. Over the last 20 y, a marked development in HMV has been noted in terms of its prevalence and the changing proportion of patients with various indications. However, data on HMV come exclusively from the developed countries of Europe and North America. Nowadays, we can see the emergence of HMV in less developed countries. This study aimed to describe the development of HMV in Poland. METHODS: Data from the largest HMV centers were retrospectively evaluated with regard to cause of respiratory failure, ventilation technique, and characteristics of the HMV-implementing institution. RESULTS: The number of subjects treated with HMV increased from 8 in 2000 to 928 in 2010. Neuromuscular diseases remained the main indication. However, their relative contribution decreased from 100 to 51% in favor of pulmonary diseases (an increase from 0 to 21%) and hypoventilation syndromes (0% in 2000 and 11% in 2010). The majority of the HMV population treated between 2000 between 2008 was ventilated by tracheostomy; however, since 2007, the percentage of subjects on noninvasive ventilation significantly increased and was equal to the number of tracheostomized subjects. HMV was initiated mainly in ICUs. However, their role systematically diminished, and an increasing number of subjects were recruited in respiratory departments. CONCLUSIONS: The prescription pattern of HMV in Poland has evolved, and there is a clear shift from neuromuscular to respiratory diseases. The prevalence of ventilation via tracheostomy still remains very high in comparison with other European countries. The Polish experience could be useful for countries with emerging HMV care systems.

Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is a very rare autosomal recessive form of spinal muscular atrophy manifested in low birth weight, diaphragmatic palsy and distal muscular atrophy. Caused by a mutation in the IGHMBP2 gene, the disease is addressed here by reference to five Polish patients in which SMARD1 has been confirmed genetically. All presented a severe form of the disease and had evident symptoms during the second month of life; with four displaying weak cries, feeding difficulties and hypotonia from birth. Two were afflicted by severe dysfunction of the autonomic nervous system. Ultrastructural analysis of a muscle biopsy revealed progressive degeneration within the nuclei of the muscle cells and Schwann cells. Neuromuscular junctions were also defective. It proved possible to identify in our patients 6 novel IGHMBP2 mutations: three missense (c.595G>C, c.1682T>C and c.1794C>A), two nonsense (c.94C>T and c.1336C>T) and one in-frame deletion (c.1615_1623del). One nonsense mutation (c.429C>T) that had been described previously was also identified. Observation of our patients makes it clear that clinical picture is still the most important factor suggesting diagnosis of SMARD1, though further investigations concerning some of the symptoms are required. As the IGHMBP2 gene is characterized by significant heterogeneity, genetic counseling of affected families is rendered more complex. IGHMBP2 protein deficiency can lead to the degeneration of nuclei, in both muscle and Schwann cells.

Data on the epidemiology of invasive Candida infections in paediatric patients in Europe are still limited. The aim of this retrospective study was to analyse the epidemiology of candidaemia in a tertiary paediatric hospital in Poland from 2000 to 2010. Using microbiological records, a total of 118 episodes of candidaemia were identified in 114 children, with an annual incidence of 0.35 episodes/1000 discharges. The highest incidences were found in the medical intensive care unit (5.28), and in neonatal intensive care (1.47). The mortality rate was 8.5%. Candida albicans and C. parapsilosis were the most prevalent species (39.8% and 35.6% respectively). The prevalence of non-albicans species increased from 12.5% in 2000 to 70% in 2010. No differences were found between C. albicans and C. non-albicans episodes in terms of demographics, risk factors or mortality. The highest resistance rates (overall 7.6%) were observed for fluconazole (4.3% in C. albicans, 7.1% in C. parapsilosis and 13.8% in other Candida species). Resistance to amphotericin B (2.5%) was limited to non-albicans isolates. The dynamic changes in species distribution and increasing resistance of fungal pathogens confirm the importance of epidemiological surveillance.

UNLABELLED: We describe a child with dyslexia and difficulty in school who, at the age of 13 years, began to suffer from several head injuries resulting from falls of uncertain cause. Two years later, the patient developed symptoms of a severe mitochondrial disorder (involving bulbar-pyramidal paralysis, ophthalmoplegia, and hyperlactatemia) that coincided with VPA administration. Brain MR imaging revealed rapidly developing Leigh syndrome (LS), and muscle biopsy showed ragged blue fibres (RBF). A diminished expression of the E1α subunit of pyruvate dehydrogenase was found in muscle homogenate (signal 28.7% of normal). The accurate diagnosis of mitochondrially inherited LS (MILS) and the identification of an almost homoplasmic m.8344G>A mutation in the MTTK gene was delayed due to an initial incorrect diagnosis of epilepsy, misdiagnosis of neuroinfection, and failure to note LS on the first brain MRI. Periods of exacerbation or improvement were observed in association with the administration of certain drugs or procedures (VPA administration or intensive rehabilitation associated with worsening; ketogenic diet associated with remission). However, the random association of these factors with natural disease fluctuations cannot be excluded. CONCLUSIONS: 1) To improve the early detection of mitochondrial disorder, we recommend screening for mtDNA (and nDNA) mutations in all patients with LS present on brain MRI. 2) Brain MRI protocols should include diffusion-weighted and T2-weighted imaging, and LS-like changes should be analysed by a neuroradiologist experienced in the field. 3) Additional controlled studies are urgently needed to assess the causal relationship between management strategies and the natural history of the disease. Until the association between VPA and disease exacerbation can be ruled out, VPA should be avoided in patients with these symptoms unless the mitochondrial disorder has been excluded.
