Forty-eight patients with endoscopically proven duodenal ulcer (DU) and Helicobacter pylori infection detected by 14C-urea breath test (BT) were assigned to 5 days of treatment with furazolidone, metronidazole, and amoxicillin in addition to eventual classical anti-ulcer agents if necessary. Clinical evaluation and BT were repeated at 2, 6, and 18 months after therapy to determine H. pylori eradication or reinfection. Endoscopy was also repeated at 6 and 18 months after treatment to detect DU relapse. In 29 (60%) patients H. pylori had been eradicated at 2 months after therapy, and in 19 (40%) infection persisted. After successful eradication, 6 of 29 (20.7%) were reinfected. All 24 patients who were negative at the 18-month evaluation were asymptomatic, free of anti-ulcer drugs, and with healed ulcers, whereas among the 19 positive patients followed up, 11 (57%) continued to be symptomatic and still using anti-ulcer agents (p less than 0.010), and 10 (53%) showed active ulcers at endoscopy (p less than 0.010). H. pylori eradication is clearly followed by long-term remission of DU. Reinfection may be an additional problem in treating DU patients in developing countries.
Objective: To analyze chronotype, duration and quality of sleep among elite athletes, to compare differences in sleep variables between sex, and to compare differences between athletes of individual and team sports. Method: The sample included 70 Brazilian elite athletes of both sex (male=37; female=33) with a mean age 23.0 ± 4.0 years old. To measure sleep-wake cycle, athletes wore an actigraph on the wrist for 10 days. Moreover, athletes answered the chronotype questionnaire of Horne and Östberg. Results: The most athletes are intermediate-type (n=55, 78.6%), with a mean of 07h:18min of sleep per night. The athletes demonstrated higher sleep fragmentation (39.26 ± 23.66 minutes) and higher sleep latency (30.88 ± 16.19 minutes) during pre-competition training days. Additionally, the athletes of individual sports demonstrated more fragmentation (p<0.001) and less sleep efficiency (p<0.001) compared athletes of team sports. However, there was no significant difference in all sleep variables between the male and female sex. Conclusion: The overall elite athletes presented poor sleep quality during the training periods prior to the Rio 2016 Olympic Games, and individual athletes showed higher fragmentation and poorer sleep efficiency compared to team athletes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
