The anthocyanin delphinidin is a natural compound found as water-soluble pigment in coloured fruits and berries. Anthocyanin-rich diets have earlier been proposed to have bone protective effects in humans and mice, but the underlying mechanisms remain unclear. In this study, we used a medaka (Oryzias latipes) osteoporosis model to test the effects of delphinidin on bone cells in vivo. In this model, inducible transgenic expression of receptor-activator of NF-kβ ligand (Rankl) leads to ectopic formation of osteoclasts and excessive bone resorption, similar to the situation in human osteoporosis patients. Using live imaging in medaka bone reporter lines, we show that delphinidin significantly reduces the number of osteoclasts after Rankl induction and protects bone integrity in a dose-dependent manner. Our in vivo findings suggest that delphinidin primarily affects the de novo differentiation of macrophages into osteoclasts rather than the recruitment of macrophages to sites of bone resorption. For already existing osteoclasts, delphinidin treatment affected their morphology leading to less protrusions and a more spherical shape. Apoptosis rates were not increased by delphinidin suggesting that osteoclast numbers were reduced primarily by impaired differentiation from macrophage progenitors and reduced maintenance of pre-existing osteoclasts. Importantly, and in contrast to previously reported cell culture experiments, no effect of delphinidin on osteoblast differentiation and distribution was observed in medaka in vivo. Our study is the first report on the effects of delphinidin on bone cells in fish embryos, which are a unique model system for compound testing that is suitable for live imaging of bone cell behaviour in vivo.

Children in particular are prime candidates for ultrasound, as they are both usually thinner than adults and are particularly at risk from the harmful effects of ionizing radiation. In this two-part article, we propose 10 uses of POCUS that pediatricians can apply to their practice in both inpatient and outpatient settings. [Pediatr Ann. 2020;49(3)e147-e152.]. Copyright 2020, SLACK Incorporated.Atopic dermatitis (AD) is the most common inflammatory skin condition in pediatric patients. AD has long been associated with comorbidities including food allergies, asthma, and allergic rhinitis, but recent literature has expanded this list to include attention-deficit/hyperactivity disorder and depression. AD has tremendous impact on quality of life for both affected children and their families. Improved understanding of AD pathogenesis, particularly regarding skin barrier dysfunction, the role of the cutaneous microbiome, and immune dysregulation, has spawned exciting new therapeutic directions. Although good skin care and appropriate use of topical corticosteroids remain first-line treatment, more precisely targeted treatments hold great promise. A recently approved topical phosphodiesterase inhibitor, crisaborole, and a subcutaneously administered interleukin-4/interleukin-13 blocker, dupilumab, are the first of what will likely be many new treatment options for patients with AD.

Copyright 2020, SLACK Incorporated.Cutaneous adverse drug reactions (ADRs) are commonly seen in the pediatric population in both inpatient and outpatient settings and are important to identify, evaluate, and appropriately manage. Early recognition and proper classification of a cutaneous drug reaction allows the clinician the ability to narrow in on a culprit drug and determine whether the medication is safe to continue. This review discusses the clinical presentation, categorization, and management of cutaneous ADRs in the pediatric population. [Pediatr Ann. 2020;49(3)e132-e139.]. Copyright 2020, SLACK Incorporated.Infestations and arthropod bite reactions in children are common reasons for presentation to pediatric health care providers. Infestations in children include head lice, scabies, and other mites. Fleas and bed bugs are common causes of bite reactions in children, and papular urticaria is a chronic, recurrent eruption resulting from delayed hypersensitivity to a variety of insect bites. Both infestations and bite reactions may result in severe pruritus with associated sleep disturbance and can be a source of significant distress for patients and families. In this review, we discuss infestations and bite reactions affecting pediatric patients, along with the approach to treatment and prevention of these conditions. [Pediatr Ann. 2020;49(3)e124-e131.].

In the last several decades, we have seen a shift in the epidemiology of many of these diseases. After being deemed eliminated at the turn of 21st century, measles has experienced a resurgence secondary to falling vaccination rates, raising public health concerns. A new variant of hand, foot, and mouth disease caused by coxsackievirus A6 has been associated with more widespread and atypical disease, which can present diagnostic challenges to clinicians. Bafilomycin A1 datasheet Parvovirus B19, which is traditionally associated with fifth disease, is also the leading cause of papular purpuric gloves and socks syndrome, a rare condition with which providers may be unfamiliar. Since the introduction of routine vaccination, there has been a shift in the epidemiology and clinical presentation of primary varicella and herpes zoster. Finally, the recently described phenomenon of Mycoplasma pneumoniae-induced rash and mucositis will be discussed. [Pediatr Ann. 2020;49(3)e116-e123.].

Pediatric providers are on the forefront of managing the disease, often as a secondary concern in a busy practice. Therefore, every provider needs to have an acne treatment plan that is effective, easy to communicate, and simple to follow. This article provides treatment rationale and guidelines-based recommendations for the initial treatment of acne, tips for troubleshooting any side effects, and a plan for subsequent follow-up to maintain good control.

Copyright 2020, SLACK Incorporated.Adequate sleep in infancy and beyond is important for development; however, many children are not sleeping the recommended amount. During the first few years of childhood, infants are frequently seen in the pediatric office for well-visits and a myriad of other concerns, including sleep difficulties. As such, pediatricians should be adequately prepared to address these concerns. This article aims to provide clinicians with a basic knowledge of sleep physiology, sleep patterns and development, and current guidelines and options available for parents to address these issues.

Despite introduction of chelation therapy, heart failure after cardiomyopathic manifestations is still a major threat to patients. METHODS We performed a search of relevant English-language literature, retrieving publications from the PubMed database and the Google Scholar search engine (2005-2018). We used "thalassemia major", "cardiomyopathy", "iron overload", "cardiac magnetic resonance T2" "chelation therapy", and "iron burden" as keywords. RESULTS The results of the studies we found suggest that cardiac hepcidin is a major regulator of iron homeostasis in cardiac tissue. Unlike previous assumptions, the heart appears to have a limited regeneration capability, originating from a small population of hypoxic cardiomyocytes. CONCLUSIONS Oxygen levels determine cardiomyocyte gene-expression patterns. Upregulation of cardiac hepcidin in hypoxia preserves cardiomyocytes from forming out of reactive oxygen species catalyzed by free cellular iron in cardiomyocytes. Using the limited regeneration capacity of cardiac cells and gaining further understanding of the cellular aspects of cardiomyopathic manifestations may help health care professionals to develop new therapeutic strategies. © American Society for Clinical Pathology 2019.

We assessed associations of different sex hormones with incidence of any bone fracture or hip fracture in older men. PARTICIPANTS AND METHODS Analysis of 3307 community-dwelling men aged 76.8 ± 3.5 years, median follow-up period of 10.6 years. Plasma testosterone (T), dihydrotestosterone (DHT), and estradiol (E2) assayed by mass spectrometry, sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) using immunoassay. Incident fractures determined via data linkage. We analyzed probability of fracture and performed Cox regression adjusted for age, medical comorbidities, and frailty. RESULTS Incident fractures occurred in 330 men, including 144 hip fractures. Probability plots suggested nonlinear relationships between hormones and risk of any fracture and hip fracture, with higher risk at lower and higher plasma T, lower E2, higher SHBG, and higher LH. In fully adjusted models, there was a U-shaped association of plasma T with incidence of any fracture (Quartile 2 [Q2] versus Q1 fully adjusted hazard ratio [HR] = 0.69, 95% confidence interval [CI] 0.51-0.94, P = .020; Q3 HR 0.59, 95% CI 0.42-0.83, P = .002) and hip fracture (Q2 versus Q1 HR 0.60, 95% CI 0.37-0.93, P = .043; Q3 HR 0.52, 95% CI 0.31-0.88, P = .015). DHT, E2, and LH were not associated with fracture. Higher SHBG was associated with hip fracture (Q4 versus Q1 HR 1.76, 95% CI 1.05-2.96, P = .033). CONCLUSIONS Midrange plasma T was associated with lower incidence of any fracture and hip fracture, and higher SHBG with increased risk of hip fracture. Circulating androgen rather than estrogen represents a biomarker for hormone effects on bone driving fracture risk. © Endocrine Society 2020. All rights reserved.

METHODS The carbapenem-resistant P. vulgaris strain BC22 was isolated from a faecal swab from a diseased pig with diarrhoea in Sichuan Province of China in 2018. The presence of carbapenemase genes was screened by PCR. WGS and bioinformatics analysis were performed to analyse the genetic environment of the carbapenem resistance determinant. RESULTS P. vulgaris strain BC22 was found to harbour the carbapenemase gene blaNDM-1. WGS data revealed that blaNDM-1 was located in a truncated ISAba125 composite transposon. The carbapenem resistance gene blaNDM-1 and 20 other resistance genes, including the multiresistance gene cfr and the bifunctional aminoglycoside/quinolone resistance gene aac(6')-lb-cr, were located in a novel SXT/R391 integrative and conjugative element (ICE). This new SXT/R391 ICE of 148.7 kb was chromosomally located, and could be transferred to Escherichia coli. CONCLUSIONS Here, we report a carbapenemase gene, blaNDM-1, integrated into an SXT/R391 ICE.
