The application of subdermal vascular network skin graft in severed finger reunion with small area skin defects / 中国医师进修杂志

Objective To explore the application of subdermal vascular network skin graft in severed finger reunion with small area skin defects.Methods Modified subdermal vascular network,which was inversion thin and middle thick,was used to repair defect of severed finger reunion without exposure of blood vessel.There were 10 patients and 14 fingers,including 7 patients and 10 fingers injured in the dorsal sid with 5 fingers' extensor tendon exposed,and 3 patients and 4 fingers injured in the palmar side with 2 patients' flexor tendon exposed.The defect area was ranged from 1.0 cm × 0.8 cm to 3.0 cm × 1.5 cm.Results In 6 larger subdermal vascular network,skin's edge became blue and blister appeared in the middle.The others was good with skin texture and aspect.Conclusions Modified subdermal vascular network skin graft is safe and effective choose to solve severed finger reunion with smnall area skin defects.

Effects of fasting during Ramadan month on cognitive function in Muslim athletes

Our study aimed to profile the effect of fasting during the Ramadan month on cognitive function in a group of healthy Muslim athletes. Eighteen male athletes underwent computerized neuropsychological testing during [fasting] and after [non-fasting] Ramadan. Diet was standardized, and tests were performed at 0900h and 1600h to characterize potential time-of-day [TOD] interactions. Psychomotor function [processing speed], vigilance [visual attention], visual learning and memory, working memory [executive function], verbal learning and memory were examined. Capillary glucose, body temperature, urine specific gravity, and sleep volume were also recorded. Fasting effects were observed for psychomotor function [Cohen's d=1.3, P=0.01] and vigilance [d=0.6, P=0.004], with improved performance at 0900h during fasting; verbal learning and memory was poorer at 1600h [d=-0.8, P=0.03]. A TOD effect was present for psychomotor function [d=-0.4, P<0.001], visual learning [d=-0.5, P=0.04], verbal learning and memory [d=-1.3, P=0.001], with poorer performances at 1600h. There was no significant fasting effect on visual learning and working memory. Our results show that the effect of fasting on cognition is heterogeneous and domain-specific. Performance in functions requiring sustained rapid responses was better in the morning, declining in the late afternoon, whereas performance in non-speed dependent accuracy measures was more resilient
