Background
Posterior urethral valves (PUV) are a common cause of end-stage renal failure in childhood. Our aim was to describe a cohort of patients with PUV and to investigate the predictors of renal impairment.Methods
We performed a retrospective chart review of children with PUV who were followed at King Abdulaziz University hospital between 2002 and 2011.Results
The cohort comprised 68 boys. There was a significant difference in the duration of follow-up (p?=?0.024), nadir serum creatinine (p?<?0.001), and last known serum creatinine level (p?=?0.001) between the patients with and without renal impairment. The duration of follow-up appeared to be a significant predictor for serum creatinine doubling (p?=?0.003; odds ratio, 1.8). There was no difference in the age of presentation, age at the time of the study, and first or last serum creatinine between children who initially had vesicostomy and children who had ablation.Conclusions
Ablation of PUV or vesicostomy did not influence kidney function in our study cohort. Children with a normal nadir serum creatinine who presented early had a better outcome. 相似文献93.

Objectives. To assess the health related quality of life (HRQoL) and the change in the NYHA class after coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in the management of stable coronary artery disease (CAD). The study was non-randomized. CABG group consisted of 240 patients and 229 patients were treated with PCI. HRQoL was measured prospectively by the 15D instrument. Results. Three-year survival was 95.0 and 95.6% (NS). The HRQoL improved statistically in both groups until 6 months after treatment but deteriorated towards the end of the follow-up of 36 months. Clinically evident improvement of the HRQoL and decrease of the NYHA class took place more frequently among CABG patients. Conclusions. Despite initially more serious preoperative state and more demanding procedure CABG patients achieve equal level of HRQoL when compared with PCI patients. CABG patients may also obtain better relief from symptoms in mid-term follow-up. HRQoL cannot be the only factor to determine outcome after invasive treatment of CAD but it has to be placed in the context of the overall situation. 相似文献

It is unclear whether symptoms of autism spectrum disorder (ASD) in young children in the population fit the three-factor structure of ASD as described in the DSM-IV, and cluster together in individual subjects. This study analysed questionnaire data on ASD symptoms filled in by mothers of 11,332 18-month-old children that was collected in the context of the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health. Confirmatory Factor Analyses showed that the three-factor model had a significantly better fit then the two- and one-factor model of ASD symptoms. Latent class analysis revealed four homogeneous groups of children (classes) with different scores for Social Interaction and Communication at one hand and Stereotypies/Rigidity at the other hand. 相似文献

Mercury is a toxic metal shown to have harmful effects on human health. Several studies have reported high blood mercury concentrations as a risk factor for autism spectrum disorders (ASDs), while other studies have reported no such association. The goal of this study was to investigate the association between blood mercury concentrations in children and ASDs. Moreover, we investigated the role of seafood consumption in relation to blood mercury concentrations in Jamaican children. Based on data for 65 sex- and age-matched pairs (2?C8 years), we used a General Linear Model to test whether there is an association between blood mercury concentrations and ASDs. After controlling for the child??s frequency of seafood consumption, maternal age, and parental education, we did not find a significant difference (P = 0.61) between blood mercury concentrations and ASDs. However, in both cases and control groups, children who ate certain types of seafood (i.e., salt water fish, sardine, or mackerel fish) had significantly higher (all P < 0.05) geometric means blood mercury concentration which were about 3.5 times that of children living in the US or Canada. Our findings also indicate that Jamaican children with parents who both had education up to high school are at a higher risk of exposure to mercury compared to children with at least one parent who had education beyond high school. Based on our findings, we recommend additional education to Jamaican parents regarding potential hazards of elevated blood mercury concentrations, and its association with seafood consumption and type of seafood. 相似文献

Objective: To evaluate the effect of regular exercise on maternal arterial blood pressure (BP) at rest and during uphill walking, in healthy former inactive pregnant women. Methods: A single-blind, single-center, randomized controlled trial including 61 out of 105 healthy, inactive nulliparous pregnant women, initially enrolled in a controlled trial studying the effect of 12 weeks of aerobic exercise (60 min 2/week) on maternal weight gain. Primary outcome was the mean adjusted difference in change in resting systolic and diastolic BP from baseline to after intervention. Secondary outcome was the mean adjusted difference in change in systolic BP during uphill treadmill walking at critical power. Measurements were performed prior to the intervention (gestation week 17.6 ± 4.2) and after the intervention (gestation week 36.5 ± 0.9). Results: At baseline, resting systolic and diastolic BP was 115/66 ± 12/7 and 115/67 ± 10/9 mmHg in the exercise (n = 35) and control group (n = 26), respectively. After the intervention, resting systolic BP was 112 ± 8 mmHg in the exercise group and 119 ± 14 mmHg in the control group, giving a between-group difference of 7.5 mmHg (95% CI 1.5 to 12.6, p = 0.013). Diastolic BP was 71 ± 9 and 76 ± 8 mmHg, with a between-group difference of 3.9 mmHg (95% CI ?0.07 to 7.8, p = 0.054). During uphill treadmill walking at critical power, the between-group difference in systolic and diastolic BP was 5.9 mmHg (95% CI ?4.4 to 16.1, p = 0.254) and 5.5 mmHg (95% CI –0.2 to 11.1, p = 0.059), respectively. Conclusions: Aerobic exercise reduced resting systolic BP in healthy former inactive pregnant women. 相似文献

We sought to characterize the incidence of AR progression and determine risk factors for AR progression in a consecutive series of infants and children after surgical correction of congenital aortic valvular and supravalvular stenosis. N = 30 patients underwent repair of the aortic valve for isolated congenital aortic valve stenosis (n = 14, 47 %) or combined with aortic regurgitation (AR, n = 16, 53 %). N = 27 (90 %) had a valvular and n = 3 patients (10 %) presented with supravalvular pathology of their aortic valve. In n = 16 patients (53 %) a bicuspid and in n = 2 (6 %) patients, a unicuspid valve was present. Comparative survival was analyzed using the Cox model and log-rank calculations. Log-rank calculations were performed for variables reaching statistical significance in order to identify differences in survival between groups. Commissurotomy was performed in n = 20 patients, patch implantation in n = 4, cusp shaving in n = 8, cusp prolapse correction in n = 3, and cusp augmentation in n = 4 patients. In patients with combined dysfunction and preoperative AR, AR was successfully reduced by the initial procedure, and postoperatively the overall median AR grade was 1+ (range 0–2.5+, p = 0.001, for AR reduction among patients with any grade of preoperative AR). By the time of follow-up echocardiography, the median AR grade had significantly progressed toward 1.5+ (p = 0.004). At the time of mid-term follow-up at 3.2 years, none of the patients had moderate or severe AR grades >2.5+. Patients with a monocuspid aortic valve and patients who had some kind of patch implantation into their cusps or commissures or shaving of thickened cusps were more likely to present with progression of aortic regurgitation. Monocuspid aortic valve and patch implantation, as well as cusp shaving, are probably linked to AR progression. The standard procedure of commissurotomy results in an absolute rate of AR progression of 40 % over a medium-term follow-up period. 相似文献

There are limited published data on pediatric organ donation rates. The aim of this study was to describe the trends in pediatric organ donation over time and to assess the regional variation in pediatric deceased organ donation. OPTN data were utilized to assess the trends in pediatric organ donation over time. The number of deceased pediatric organ donors was indexed using regional mortality data obtained from the National Center for Health Statistics and compared across UNOS regions and two different eras. The number of pediatric deceased organ donors has declined in the recent era, largely driven by fewer adolescent donors. For all age groups, there is significant regional variation in organ donation rates, with identifiable high‐ and low‐performing regions. Expansion of the donor pool may be possible by optimizing organ donation in regions demonstrating lower recruitment of pediatric donors. Using the region with the highest donation rate for each age group as the gold standard, we estimate a potential 24% increase in the number of donors if all regions performed comparably, equating to 215 new pediatric donors annually. 相似文献
