She notes that in the past, epilepsy was not considered as a specialty and was looked after by all paediatricians; it is recognised now that it is an incredibly complex group of conditions, which deserves to have specialist management. She believes that although modern technology is crucial in informing and educating families, face to face education and advice is still the most important method of providing support. She highlights the recent advances in genetics of paediatric neurology along with the drive for epilepsy specialists, both nursing and medical, while she estimates that over the following years, paediatric epilepsy nursing will have progressed beyond nowadays expectations.Retinopathy of prematurity (ROP) is a sight-threatening disorder of the retina affecting neonates of very low birth weight and gestational age, and is characterized by the development of abnormal blood vessel growth. According to Dr Dimitra Skondra, Associate Professor of Ophthalmology and Vitreoretinal Surgeon at the University of Chicago School of Medicine in Chicago, USA, the neonatal gut microbiome may be implicated in the neoangiogenesis process in the neonatal retina and this role may be one of the missing links in the pathogenesis of ROP. The human gut microbiome consists of bacteria, viruses, protozoa and fungi, which colonize the sterile fetal intestine, and differ depending on gestational age, mode of delivery, type of neonatal feeding, the usage of antibiotics and the requirement of neonatal intensive care. To date, it has been related to multiple nutritive, metabolic and immunological functions and has been implicated in the pathogenesis of several human diseases, such as the inflammatory bowel diseases, autoimmune and neurogenerative disorders, metabolic syndrome, cardiovascular diseases and various types of malignant neoplasias. Recent research has proposed that the neonatal gut microbiome profile in high-risk neonates who develop ROP is significantly enriched with Enterobacteriacaea species several weeks prior to the diagnosis of ROP. Further research using animal models is required to prove the causative or secondary role of the microbiome composition in the development and clinical course of ROP. If this role is proven, the gut microbiome could then be a target of intervention for personalized medicine in the prevention and therapeutic management of ROP in neonates.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted to humans mainly via contact and droplet transmission and its entry into cells is mediated by the efficient binding of the spike (S) viral protein with the angiotensin converting enzyme-2 (ACE2) receptors. Although acute respiratory distress syndrome (ARDS) caused by SARS-CoV-2 fulfills the criteria of the Berlin definition, in a considerable proportion of patients with COVID-19, there is a dissociation between their relatively well-preserved lung mechanics and the severity of hypoxaemia. The extent of pneumococcal related morbidity and mortality is largely unknown. Respiratory comorbidities that increase the risk of severe disease and mortality due to SARS-CoV-2 include chronic obstructive pulmonary disease, asthma, bronchiectasis and fibrotic interstitial lung diseases, regardless of aetiology. Pneumococcal and seasonal influenza vaccinations are useful in preventing a substantial burden of mortality in high-risk populations, while general quarantine and social distancing can reduce the infiltration of the virus within the community. To date, several therapeutic agents have been studied or are currently examined, such as hydroxychloroquine, chloroquine, ritonavir/lopinavir, remdesivir, colchicines and interleukin-6 inhibitors. However, the usage of most of these into clinical practice was not based on randomised clinical trials and their results should be viewed with extreme caution; remdesivir seems to be the more promising option. Rigorous efforts are under way for the development of a safe and successful vaccine against SARS-CoV-2.Paediatric virology is a bold, new scientific field, where paediatrics focuses on the newly acquired knowledge from clinical virology, enriched with current advances in epidemiology, molecular medicine, evidence-based medicine, clinical governance, quality improvement, pharmacology and immunology. Although there are several methods with which to obtain training in paediatric viral infections in the UK, paediatric virology does not currently exist as a specific subspecialty. The aim of the present article was to present the existing educational platforms and training options in paediatric virology in the UK available to trainees wanting to pursue a clinical and/or academic career in paediatric virology.Tumor hypoxia contributes to the development of resistance to chemotherapeutic drugs in several human cancer cell lines. Atovaquone, an anti-malaria drug approved by the US Food and Drug Administration, has recently demonstrated anti-cancer effects in vitro and in vivo in several cancer models. To assess the potential of atovaquone as an anti-cancer agent under hypoxia in colorectal carcinoma, EpCAM+CD44+ colon cancer stem cells were isolated from HCT-116 human colon cancer cells through magnetic-activated cell sorting. Seladelpar clinical trial The efficacy of atovaquone on cytotoxicity, tumorsphere formation, apoptosis, invasion and cell-cycle progression under hypoxic conditions were evaluated. MTS assays indicated that atovaquone inhibited the proliferation of EpCAM+CD44+ HCT-116 cells with a half-maximal inhibitory concentration of 15 µM. Atovaquone inhibited tumorsphere formation and cell proliferation by causing cell-cycle arrest in S-phase, which induced apoptosis of EpCAM+CD44+ HCT-116 cells, as detected by Annexin V-FITC/PI double staining assays, and caused mitochondrial membrane potential depolarization, as determined by a JC-1 staining assay. Reverse transcription-quantitative PCR demonstrated increased expression of Bax and downregulation of Bcl-2. Transwell invasion assays indicated that atovaquone inhibited the invasiveness of EpCAM+CD44+ HCT-116 cells under hypoxia, which was associated with upregulation of MMP-2 and -9 and increased expression of tissue inhibitor of MMPs (TIMP)-1. Taken together, atovaquone reduced the tumorsphere formation and invasion ability of EpCAM+CD44+ HCT-116 cells, at least in part by increasing the expression of TIMP-1 and downregulating the expression of MMP-2 and -9, as well as the cells' viability by inducing cell-cycle arrest in S-phase and induction of apoptosis via the Bcl-2/Bax pathway under hypoxic conditions. Further studies are warranted to explore the mechanisms of action of atovaquone as a promising anticancer agent in the treatment of colorectal carcinoma.
