7% (90 insertions). There were 21 complications (21.6%), including 17 extravasations (17.5%) of fluid and four dermal abrasions (4.1%). We found no cases of complications that may have compromised patient safety. Conclusions The success rate of the EZ-IO insertion was high in paediatric patients. However, we found a higher incidence of dermal abrasions, which might be a complication specific to children.Background Reluctance to use intravenous (IV) iron for the treatment of iron deficiency continues due to a perceived high risk of severe hypersensitivity reactions (HSRs). Additionally, it has been hypothesized that 'dextran-derived' IV iron products (e.g., ferumoxytol [FER] and ferric derisomaltose/iron isomaltoside 1000 [FDI]) have a higher risk of severe HSRs than 'non-dextran-derived' products (e.g., ferric carboxymaltose [FCM] and iron sucrose [IS]). In the present analysis, HSR data from head-to-head randomized controlled trials (RCTs) with IV iron products were evaluated to determine if differences in safety signals are present among these IV iron formulations. Study design and methods Reported serious or moderate-to-severe HSR incidence data from five RCTs (FIRM; FERWON-NEPHRO/-IDA; PHOSPHARE-IDA04/-IDA05) were used to calculate risk differences with 95% confidence intervals (CIs) for FER, FCM, FDI, and IS. The rates and risk differences for these HSRs were compared. Results The analysis included data for 5247 patients FER (n = 997), FCM (n = 1117), FDI (n = 2133) and IS (n = 1000). Overall rates of serious or moderate to severe HSRs were low (0.2%-1.7%). The risk differences (95% CIs) showed small differences between the IV iron formulations FER versus FCM, -0.1 (-0.8 to 0.6); FDI versus IS, 0.1 (-0.3 to 0.5); FDI versus FCM, -0.9 (-3.7 to 1.9). Conclusion RCT evidence confirms a low risk of serious or moderate to severe HSRs with newer IV iron formulations and no significant differences among existing commercially available products. selleck chemicals llc Thus, RCT data show that the supposed classification of dextran-derived versus non-dextran-derived IV iron products has no clinical relevance.Background Recent studies have shown that fluoroquinolones, specifically, enrofloxacin and its active metabolite (ciprofloxacin), cross the equine placenta without causing gross or histological lesions in the first and third trimester fetuses or resulting foal. However, it is possible that in utero exposure to fluoroquinolones may cause subtle lesions not detectable by standard means; thus, a more in-depth assessment of potential toxicity is warranted. Objectives To utilise quantitative magnetic resonance imaging (qMRI), biomechanical testing, and chondrocyte gene expression to evaluate the limbs of foals exposed to enrofloxacin during the third trimester of pregnancy. Study design In vivo and control terminal experiment. Methods Healthy mares at 280d gestation were assigned into three groups untreated (n=5), recommended therapeutic (7.5 mg/kg enrofloxacin, PO, SID, n=6), or supratherapeutic (15 mg/kg, PO, SID, n=6) doses for 14d. Mares carried and delivered to term and nursed their foals for ~30d. Two additi be a safe and useful antibiotic for select bacterial infections in pregnant mares.Cell senescence is due to the permanent cell cycle arrest that occurs as a result of the inherent limited replicative capacity toward the Hayflick limit (replicative senescence), or in response to various stressors (stress-induced premature senescence, SIPS). With the acquisition of the senescence-associated secretory phenotype (SASP), cells release several molecules (cytokines, proteases, lipids), and express the senescence-associated beta-galactosidase (SA-β-Gal). link2 Here we tested whether vitamin E affects SA-β-Gal in an in vitro model of cell ageing. Skin fibroblasts from human subjects of different age (1, 13, 29, 59, and 88 years old) were cultured until they reached replicative senescence. At different passages (Passages 2, 9, 13, and 16), these cells were treated with vitamin E for 24 hr. Vitamin E reduced SA-β-Gal in all cells at passage 16, but at earlier passage numbers it reduced SA-β-Gal only in cells isolated from the oldest subjects. Therefore, short time treatment with vitamin E decreases SA-β-Gal in cells both from young and old subjects when reaching replicative senescence; but in cells isolated from older subjects, a decrease in SA-β-Gal by vitamin E occurs also at earlier passage numbers. The possible role of downregulation of CD36 by vitamin E, a scavenger receptor essential for initiation of senescence and SASP, is discussed.Aim The aim of this narrative review was to provide a comprehensive summary of the characteristics of gastrointestinal (GI) involvement in the most common paediatric primary vasculitides. Methods We used PubMed to primarily identify papers, reviews, case series and editorials published in English from 2000 until 31 January 2020. Based on this, we report the prevalence, clinical manifestations, diagnostic approaches and management of GI involvement in each vasculitis. Results Vasculitides are inflammatory blood vessel diseases and the majority can affect the GI system with vascular, GI tract or solid organ involvement. GI involvement can sometimes complicate and delay the correct diagnosis. Clinical findings are usually nonspecific symptoms, such as fever, abdominal pain, nausea, vomiting and diarrhoea. link3 Bleeding should alert paediatricians to the possibility of severe, complicated vasculitis. Diagnosis relies mostly on imaging. If it goes unrecognised, GI involvement in paediatric vasculitis is a serious cause of morbidity and even mortality, related to bowel ischaemia and perforation. Treatment of GI symptoms depends on the type of vasculitis and usually involves high-dose steroids and immunosuppressants. Conclusion GI manifestations in the most common paediatric primary vasculitides.were usually nonspecific, diagnosis mostly relied on imaging and treatment usually involved high-dose corticosteroids and immunosuppressants.Monoclonal Gammopathy of Undetermined Significance (MGUS) is a pre‐malignant clonal plasma cell disorder, with 25 to 30% life‐long risk of progression to multiple myeloma (MM).1 It is usually asymptomatic, but infrequently associated with several serious conditions, such as neuropathies, glomerulonephritis, and acquired angioedema.2 Moreover, a higher risk of infection and deep venous thrombosis has been reported in patients with MGUS.3,4Melatonin is widely involved in plant growth and stress responses as a master regulator. Melatonin treatment alters the levels of endogenous nitric oxide (NO) and NO affects endogenous melatonin content. Melatonin and NO may induce various plant physiological behavior through interaction mechanism. However, the interactions between melatonin and NO in plants are largely unknown. The review presented the metabolism of endogenous melatonin and NO and their relationship in plants. The interactions between melatonin and NO in plant growth and development and responses to environmental stress were summarized. The molecular mechanisms of interaction between melatonin and NO in plants were also proposed.The subtidal kelp Nereocystis luetkeana (hereafter Nereocystis) maintains an upright stature by producing a single gas-filled float (pneumatocyst) that provides buoyancy. The ability of Nereocystis pneumatocysts to inflate with gas underwater is peculiar, and the gas composition of pneumatocysts has been the topic of several studies over the last 100 years. Past studies of pneumatocyst gases only examined large sporophytes, leaving open questions about the origins of these gases and how gas composition may change during development. In this study, we use developmental time as a means to understand the origin and physiological mechanisms that give rise to different gases within Nereocystis pneumatocysts. Total gas composition was measured across a range of pneumatocyst sizes (5-725 mL). Contrary to previous studies that documented pneumatocyst gas concentrations to be similar to air, this study found internal gas levels of CO, CO2 , and O2 to be 1.2 ± 0.8%, 0.6 ± 0.2%, and 59.9 ± 13.6%, respectively. Our data suggest that the composition of gases does not change as pneumatocysts grow and that the rate of each gas added is approximately proportional to changes in pneumatocyst volume. Therefore, cells constituting the pneumatocyst wall are likely producing more gas (per surface area) to fill pneumatocysts as they expand, maintaining proportional gas composition and corresponding internal pressure.Purpose Standard relaxation time quantification using phase-cycled balanced steady-state free precession (bSSFP), eg, motion-insensitive rapid configuration relaxometry (MIRACLE), is subject to a considerable underestimation of tissue T1 and T2 due to asymmetric intra-voxel frequency distributions. In this work, an artificial neural network (ANN) fitting approach is proposed to simultaneously extract accurate reference relaxation times (T1 , T2 ) and robust field map estimates ( B 1 + , ΔB0 ) from the bSSFP profile. Methods Whole-brain bSSFP data acquired at 3T were used for the training of a feedforward ANN with N = 12, 6, and 4 phase-cycles. The magnitude and phase of the Fourier transformed complex bSSFP frequency response served as input and the multi-parametric reference set [T1 , T2 , B 1 + , ∆B0 ] as target. The ANN predicted relaxation times were validated against the target and MIRACLE. Results The ANN prediction of T1 and T2 for trained and untrained data agreed well with the reference, even for only four acquired phase-cycles. In contrast, relaxometry based on 4-point MIRACLE was prone to severe off-resonance-related artifacts. ANN predicted B 1 + and ∆B0 maps showed the expected spatial inhomogeneity patterns in high agreement with the reference measurements for 12-point, 6-point, and 4-point bSSFP phase-cycling schemes. Conclusion ANNs show promise to provide accurate brain tissue T1 and T2 values as well as reliable field map estimates. Moreover, the bSSFP acquisition can be accelerated by reducing the number of phase-cycles while still delivering robust T1 , T2 , B 1 + , and ∆B0 estimates.This study examines within-person and cross-person relations between depressive symptoms, harsh parenting, and parental rejection in low-income Filipino mothers and fathers of adolescents using an actor-partner interdependence model (APIM). Mother and father dyads (N = 81, Mage = 43.48, SD = 8.66) recruited from urban neighborhoods in the Philippines completed orally administered questionnaires on depressive symptoms, harsh parenting, and rejection. Results showed that mothers' scores and fathers' scores on depressive symptoms did not significantly differ and that mothers scored significantly higher than fathers on harsh parenting and rejection. Dyadic analyses using the APIM showed that the actor effect of depressive symptoms on harsh parenting was statistically significant for fathers only and that the actor effects of depressive symptoms on rejection were statistically significant for both mothers and fathers. No partner effects on harsh parenting and rejection were statistically significant. These findings contribute to the robust evidence linking parental depressive symptoms to negative parenting behaviors and highlight the need to attend to both fathers' psychological health and mothers' psychological health in efforts to reduce harsh and rejecting parenting behaviors among Filipino parents.
