Optimism is known to buffer against negative mood. Thus, understanding the factors that contribute to individual variation in optimism may inform interventions for mood disorders. Preliminary evidence suggests that the generation of mental imagery-based representations of positive relative to negative future scenarios is related to optimism. This study investigated the hypothesis that an elevated tendency to generate positive relative to negative mental imagery during spontaneous future thinking would be associated with reduced negative mood via its relationship to higher optimism. Participants (N = 44) with varied levels of naturally occurring negative mood reported current levels of optimism and the real-time occurrence and characteristics of spontaneous thoughts during a sustained attention computer task. Consistent with hypotheses, higher optimism statistically mediated the relationship between a higher proportional frequency of positive relative to negative mental imagery during spontaneous future thinking and lower negative mood. Further, the relationship between emotional mental imagery and optimism was found for future, but not past, thinking, nor for verbal future or past thinking. Thus, a greater tendency to generate positive rather than negative imagery-based mental representations when spontaneously thinking about the future may influence how optimistic one feels, which in turn may influence one's experience of negative mood.
Children born with unilateral renal agenesis (URA) are thought to have a risk of developing hypertension, proteinuria, and progressive chronic kidney disease (CKD). The present study aimed to evaluate the long-term prognosis and clinical characteristics of children with URA.

The study included 171 patients aged < 18 years diagnosed as URA who were followed-up for ≥ 1 year and 121 healthy controls matched for age, gender, and BMI.

Median age at diagnosis was 2 years (IQR 1 month-16 years) and the incidence of URA in males (65.4%) was higher than in females. Among the patients, 21 (12.2%) had other urinary system anomalies. It was noted that 2.3% of the patients had proteinuria, 15.2% had hyperfiltration, and 2.9% had CKD. Hypertension based on ambulatory blood pressure monitoring (ABPM) was diagnosed in 18 (10.5%) of the patients, of whom 10 had masked hypertension. Diastolic blood pressure in the URA patients was significantly higher than in the healthy controls. The incidence of hypertension and CKD was significantly higher in the patients with other urinary system anomalies.

Patients with a single functional kidney should be periodically evaluated throughout their lifetime for urine protein, blood pressure, and kidney functions. The most remarkable finding of this study is the importance of the use of ABPM for evaluating blood pressure in pediatric URA patients, especially for the detection of masked hypertension and the non-dipper phenomenon, which cannot be achieved with office blood pressure measurement.

Stoma is occasionally fashioned during trauma surgery. A loopogram is routinely conducted in the surgical planning for stoma reversal. This is associated with medical and cost implications. A study was undertaken to evaluate the influence of loopograms on the management of trauma patients at a Johannesburg hospital.

A retrospective analysis of records in the stoma database (January 2013 to December 2018) was conducted. The patient demographics, method of injury, stoma-type, loopogram findings and post-operative courses were analysed.

112 records were obtained. 9 (8%) patients were excluded for pending investigations or surgery. 13 (11.6%) patients were excluded for incomplete data. The remaining 90 (80.3%) patients, with a mean age of 32.9 had non-contributory loopograms and underwent a reversal procedure. 43 (47.8%) had a loop colostomy while 47 (52.2%) had undergone a Hartmann's procedure. Mechanism of injury was stab wounds (81.4%L; 61.7%H); gunshot wounds (13.9%L; 29.7%H) and blunt trauma (L5% and 9%H). selleck The post-operative complication rate was 30% for the loop group (2.3% ≥ Clavien-Dindo 3) and 25.5% for the Hartmann's group (4% ≥ Clavien-Dindo 3). The average timing to reversal was 38weeks (range 12-60) in the Hartmann's group and 22weeks (range 12-32) the loop colostomy group.

Significant findings are infrequent on loopogram for trauma patients. When these findings are detected, the effect on management is questionable. They are not without complications and have cost and time implications. Loopograms are helpful in selective cases rather than as a routine investigation, particularly in resource-limited settings.

To evaluate heating of a redilatable stent for the treatment of aortic coarctation in neonates and small children in the new imaging modality magnetic particle imaging and established magnetic resonance imaging.

The cobalt-chromium stent (BabyStent, OSYPKA AG, Rheinfelden, Germany) has a stent design which allows for redilatation and adjustment of the diameter from 6 to 16mm for a use in aortic coarctation. The stent loses its radial integrity while opening at predetermined breaking points at a diameter of 14mm or 16mm, respectively. We measured the temperature increase in the stent at different diameters during 7-min magnetic particle imaging and magnetic resonance imaging scans with fiber optic thermometers under static conditions surrounded by air. In magnetic particle imaging, stents with diameters from 6 to 16mm were tested while in magnetic resonance imaging only stents with diameters of 6mm and 14mm were investigated exemplarily.

In magnetic particle imaging, the measured temperature differences increased up to 4.
