Bertuzzi, M.D. Silva-Cavalcante, A.E. Lima-SilvaAbstractAcetaminophen has been combined with caffeine for therapeutic purpose, but the effect of co-ingestion of acetaminophen and caffeine on exercise performance has not been investigated. To determine the effect of isolated and combined ingestion of caffeine and acetaminophen on performance during a 4-km cycling time-trial (4 T T). Eleven men, completed a 4 T T one hour after the ingestion of cellulose (PLA), acetaminophen (20 mg kg-1 body mass, ACT), caffeine (5 mg kg-1 body mass, CAF) or combined acetaminophen and caffeine (20 and 5 mg kg-1 body mass, respectively, ACTCAF). The perception of pain, rating of perceived exertion, electromyography, oxygen uptake were recorded. Plasma lactate concentration was measured before and immediately after the trial. The time and mean power during the 4 T T was significantly improved (P 0.05). All other measures were similar under the conditions (P > 0.05). Caffeine but not acetaminophen increases power output ultimately increasing performance during a 4TT.Graphical abstract
We report a case of a young male with no prior genitourinary history who presents to an emergency department with sudden onset gross hematuria, clot retention, and right-sided flank pain. On evaluation, he was found to have a renal artery aneurysm bleeding into his collecting system and underwent renal artery embolization and rapid resolution of his hematuria. Renal vascular pathology should be considered in the differential diagnosis and timely diagnosis of this condition is imperative as surgical interventions have proven to be life-saving.

CONCLUSIONS: BTX-A treatment using either a trigone-sparing or trigone-including injection template resulted in significant, but not location-dependent, improvement in IC/BPS symptom scores at 30 and 90 day points post-procedure with no significant difference in post-treatment complication profiles.

CONCLUSION: Large variability exists in the definitions, methods of reporting, and analysis of PD-associated peritonitis across trials and observational studies. Standardizing definitions for reporting of peritonitis and associated outcomes will better enable assessment of the comparative effect of interventions on peritonitis. This will facilitate continuous quality improvement measures through reliable benchmarking of this patient-important outcome across centers and countries.

CONCLUSIONS: Insertion-related complications leading to significant adverse events following laparoscopic placement of PD catheters are common. Many complications occur before the start of PD. Insertion-related complications are an important area of focus for future research and quality improvement efforts. PMID: 32063191 [PubMed - as supplied by publisher]

In this study, 91 adolescents (10-24 years; 78 females) including 30 chronic pain patients with high pain-related distress, 29 chronic pain patients with low pain-related distress, and 32 healthy peers without chronic pain completed a developmentally appropriate T–S learning paradigm. We measured self-reported fear, psychophysiology (skin conductance response), and functional magnetic resonance imaging responses (N = 72 after functional magnetic resonance imaging exclusions). After controlling for age and anxiety symptoms, patients with high pain-related distress showed altered self-reported fear and frontolimbic act...
This study provided no evidence for the hypothesis that chronic pain is associated with accelerated brain aging (Welch t test, P = 0.74, Cohen's d = 0.061). A Bayesian independent-samples t test indicated moderate evidence in favor of the null hypothesis (BF01 = 4.875, ie, group means were equal). Our results provide indirect support for recent models of pain-related changes of brain structure, brain function, and cognitive functions. These models postulate network-specific maladaptive plasticity, rather than widespread or global neural degeneration.
Drawing on advances in chronic pain metrics, a simplified Graded Chronic Pain Scale-Revised was developed to differentiate mild, bothersome, and high-impact chronic pain. Graded Chronic Pain Scale-Revised was validated among adult enrollees of 2 health plans (N = 2021). In this population, the prevalence of chronic pain (pain present most or every day, prior 3 months) was 40.5%: 15.4% with mild chronic pain (lower pain intensity and interference); 10.1% bothersome chronic pain (moderate to severe pain intensity with lower interference with life activities); and 15.0% high-impact chronic pain (sustained pain-related activit...
