Background. Caffeine is widely used to treat apnea of prematurity. Here, we evaluated the efficacy of early caffeine (1-2 DOL) in decreasing the incidence of adverse neonatal outcomes. Methods. A retrospective cohort was used to compare the neonatal morbidity of 150 preterm neonates with gestational age ≤29 weeks. Infants were divided into 3 groups based on the initiation timing of caffeine the...
Five yeast species isolated from caffeine contaminated samples were screened for their capability of caffeine degradation. Based on the degradation efficiency, isolate was selected and identified as Trichosporon asahii which showed 60 % degradation of caffeine in 72 hours when caffeine was utilized as the sole carbon and nitrogen source. The influence of various factors such as pH, temperature,...
Background: Because of the increasing concern of the potential adverse effects of caffeine intake in children, recent estimates of caffeine consumption in a representative sample of children are needed. Objectives: We provide estimates of caffeine intake in children in absolute amounts (mg) and in relation to body weight (mg/kg) to examine the association of caffeine consumption with sociodemog...
introduction: the teratogenic effect of caffeine depends on the dosage and the route of administration. a daily oral dose of caffeine (80 mg/kg) is tetrogenic for rat. in present study, the teratogenic effects of caffeine on the development of bones and the resoption of skeletal cartilage in the rat embryo were quantitatively evaluation. materials and methods: three groups of pregnant rats were...
BACKGROUND Caffeine's properties as an analgesic adjuvant with nonsteroidal anti-inflammatory drugs/acetaminophen are well documented. However, little clinical research has explored caffeine's effects on opioid analgesia. This study assessed the effects of caffeine consumption on pain and other symptoms in opioid-using and nonusing chronic pain patients meeting the survey criteria for fibromyal...
Three studies investigated the influence of mood states on the processing of positive and negative information regarding caffeine consumption and on the impact of this information on one's mood, attitudes, and intentions. The results were consistent with the predictions of the mood-as-a-resource hypothesis: First, the induction of positive mood in high (compared with low) caffeine consumers enh...
Background & objectives: Caffeine can affect many physiological functions of the body. The aim of this study was to investigate the response of aerobic function, blood pressure and some immune system factors of trained men to acute caffeine consumption in dehydrated condition and warm and humid environment. Methods: Thirty male athletes with a mean age of 26.6±3.9 years in dehydrated conditions...

Energy drinks containing caffeine, taurine, and glucose may improve mood and cognitive performance. However, there are no studies assessing the individual and interactive effects of these ingredients. We evaluated the effects of caffeine, taurine, and glucose alone and in combination on cognitive performance and mood in 24-hour caffeine-abstained habitual caffeine consumers. Using a randomized,...
Caffeine and theobromine are members of the xanthine family. Coffee soft drinks contain caffeine, whereas, in cacao, is main ingredient. The mineral contents tooth which sucked caffeine-containing dam’s milk were decreased. To determine if caffeine would affect enamel, dams fed with a pups killed first second molars extracted.
