After 1 year, the spatial variability in community composition was greater than that observed among plots that predators could access. An important, but less recognized, aspect of predation is its dampening effect on variability of community structure. As accelerating rates of environmental change disrupt species interactions, variability effects of ecological processes and corresponding responses are likely to be increasingly important determinants of community dynamics.
Chronic inorganic arsenic (iAs) exposure induces deleterious effects on CNS including oxidative stress, cognitive deficits and altered brain neurochemistry. Little is known about the association between iAs and estrogen receptor expression in brain regions.
Owing to the neuroprotective and estrogenic activities of resveratrol (RES), we examined the combined effects of arsenic trioxide (As
O
) and RES on neurobehavioural functions, estrogen signalling and associated neurochemical changes in mouse hippocampus.
As
O
alone (2 and 4mg/kg bw) or along with RES (40mg/kg bw) was administered orally for 45days to adult female mice. From days 33 to 45, open field, elevated plus maze and Morris water maze tests were conducted to evaluate locomotion, anxiety and learning and memory. On day 46, animals were euthanized and brain tissue and hippocampi obtained therefrom were processed for atomic absorption spectrophotometry and western blotting respectively.
As
O
alone exposure resulted in enhanced anxiety lces cognitive impairment; hence, the modulation of estrogen-NMDAR-BDNF pathway by RES represents a potential avenue to recover behavioural deficits induced by this neurotoxin.
Tracheal trifurcation is an uncommon and often unknown type of anomalous tracheobronchial arborization, characterized by three main bronchi originating at the level of the carina. Diagnosis is important due to its clinical implications.
To highlight the anatomical, clinical and diagnostic aspects of tracheal trifurcation by reporting our experience and reviewing the literature.
We retrospectively evaluated pediatric patients referred to our institution from January 2018 to May 2020 with a diagnosis of tracheal trifurcation. All patients underwent chest radiographs, computed tomography (CT) (with/without dynamic airway scanning) and bronchoscopy. Clinical and anatomical data were collected.
Three patients with tracheal trifurcation were identified (1 female, median age 7.6±0.4months). All had associated anomalies two had tetralogy of Fallot, one with esophageal atresia/tracheoesophageal fistula and one with an atrioventricular septal defect, and the other had skeletal ciliopathy. Chest radiographs wereheobronchial anomalies, cardiovascular defects or esophageal malformations, responsible for clinical manifestations and earlier detection. Bronchoscopy is often used for diagnosis, but is invasive and may be incomplete or inconclusive, while CT allows for a noninvasive and correct diagnosis, while also highlighting additional findings in the thorax.Prompt detection of cardiovascular abnormalities in children with anorexia nervosa and physical instability requiring hospitalization is essential to identify patients at higher cardiovascular risk. We studied all anorexia nervosa children requiring admission at Paediatric Institute in the period 2015-2019. Anorexia nervosa cardiopathy at admission was defined by the presence of at least two of the following clinical findings pericardial effusion, mitral regurgitation, bradycardia, mitral billowing, aortic regurgitation, altered LV morphology and ECG abnormalities. Echocardiographic data were compared with those registered at 3-8-month follow-up and with data from a healthy population. Thirty-eight anorexia nervosa children were examined. Prevalence of anorexia nervosa cardiopathy at admission was 63% (24 patients). Pericardial effusion, bradycardia and mitral regurgitation were present together in 26% of patients. Most cardiovascular changes recovered at follow-up. Anorexia nervosa cardiopathy was associatedn if anorexia nervosa children with more severe cardiac impairment during hospitalization present higher cardiovascular-risk profile despite treatment. What is New • In anorexia nervosa children needing hospitalization for physical reasons, prevalence of acute anorexia nervosa cardiopathy at admission is high, around 60%. • By advanced echocardiography, children with anorexia nervosa cardiopathy at admission have a worse cardiac filling, impaired cardiac geometry and systolic deformation that only partially recover at mid-term follow-up.Urinary tract infection (UTI) is common in preterm infants and may have long-term sequela, such as recurrent infections and renal scarring in older children. We assessed long-term outcomes of preterm infants with UTI, born during 1996-2008 in Schneider Children's Medical Center's neonatal intensive care unit (NICU), and incidence of UTI recurrence. Of 89 preterm infants, seven were excluded due to prenatal diagnosis of congenital anomalies of the kidney and urinary tract (CAKUT), 41 interviewed by phone, 18 presented for follow-up evaluation in the nephrology clinic, and 23 lost to follow-up. No patient who completed follow-up reported additional UTI episodes or issues related to kidney and urinary tract. see more Clinically evaluated participants were 17.1 ± 3.6 years, born prematurely at 29.4 ± 4 weeks. All had a normal estimated glomerular filtration rate of >90 ml/min/1.73m2; four (22%) had systolic blood pressure >90th percentile; none had proteinuria (mean protein/creatinine ratio 0.09 ± 0.04 mg/mg) or albuminurat is New • A single episode of UTI in premature infants without CAKUT probably does not constitute a risk factor for UTI recurrence, and it is unlikely to cause renal injury in the first two decades of life. • For premature infants with UTI without sonographic diagnosis of CAKUT in NICU, prophylactic antibiotic treatment, further imaging, or long-term nephrology follow-up may be unnecessary.
Hip reconstruction is an established procedure in pediatric patients with neurogenic hip dislocation. An open triradiate cartilage provides the advantage of a high plasticity of the bone which prevents an intraarticular fracture and postoperative adaptation of shape. Some patients with dislocated hips, however, arrive late. A hip reconstruction is still feasible as shown earlier but the long-term risk for osteoarthritis, and recurrence of dislocation, and functional outcome is unknown. It is the aim of our investigation to evaluate long-term clinical and radiological outcomes of hip reconstruction by Dega type pelvic osteotomy performed after fusion of the triradiate epiphyseal cartilage in patients suffering from cerebral palsy.
We retrospectively analyzed 43 hips in 37 patients with a hip reconstruction for correction of hip dislocation or subluxation. In all patients, the triradiate cartilage was fused before surgery. Age at surgery was 15years and 2months on average and follow-up time was mean 13years 5months.
