Chronic versus acute ingestion of sodium citrate: a randomized placebo controlled cross-over trial for swimming 200 metres in well-trained swimmers age 13-17

A double-blinded, placebo controlled, cross-over design was used to investigate sodium citrate dihydrate (Na-CIT) supplementation improve 200m swimming performance. Ten well-trained, male swimmers (14.9 ± 0.4y; 63.5 ± 4kg) performed four 200m time trials: acute (ACU) supplementation (0.5g/kg), acute placebo (PLC-A), chronic (CHR) (0.1g/kg for 3 days and 0.3g/kg on the 4th day pre-trial), and chronic placebo (PLC-C). Na-CIT was administered 120min pre-trial in solution with 500mL of flavored water; placebo was flavored water. Blood lactate, base excess (BE), bicarbonate, pH, and PCO2 were analyzed at basal, 100min post-ingestion, and 3min post-trial via finger prick. Time, lactate, and rate of perceived exertion were not different between trials. BE and bicarbonate were significantly higher for the ACU and CHR trials compared to placebo. “Responders” improved by 1.03% (P=0.043) and attained significantly higher post-trial lactate concentrations in the ACU versus PLC-A trials and compared to non-responders in the ACU and CHR trials.

Laura Dexter letter, commenting on the McLeod murder trial, October 5, 1841

Alexander McLeod was Deputy Sheriff of the Niagara District during the Rebellion of 1837-38 in Upper Canada. On December 24, 1837, he became aware of a scheme by the rebels to use the American steamboat Caroline to provide supplies to William Lyon Mackenzie and his followers on Navy Island in the Niagara River. McLeod notified the authorities in Upper Canada about the situation. A few days later, on December 29, Commodore Andrew Drew led a band of men, including McLeod, to the American side, where the Caroline was moored at Schlosser’s Wharf. A scuffle ensued, in which American Amos Durfee was killed. The Caroline was then released from its moorings, set on fire, and drifted downstream before sinking. Many Americans viewed the incident as a violation of their sovereignty. Tensions between the United States and England were already strained over a boundary dispute between Maine and New Brunswick, and the situation with the Caroline further escalated the tension. McLeod was subsequently arrested in November, 1840 in Lewiston, NY and indicted for arson and murder. The British foreign secretary, Lord Palmerston, insisted that McLeod be released and could not be held personally responsible for the incident, as he was acting on orders from authorities in Canada. Eventually, McLeod was acquitted.

A randomized controlled trial evaluating the quality of life and the sense of coherence in seniors wearing complete conventional dentures or mandibular two-implant overdentures

La supériorité des prothèses mandibulaires retenues par deux implants (IODs) sur les prothèses conventionnelles (CDs) nécessitent d’être éclaircies notamment en rapport à leur influence sur la qualité de vie reliée à la santé bucco-dentaire (OHRQoL) ainsi que sur la stabilité de cet effet de traitement. De plus, l’influence des facteurs psychologiques, tel que le sens de cohérence (SOC), sur l’effet de traitement reste encore inconnue. Le but de cette étude est de déterminer l’amplitude de l’influence du port des IODs et des CDs sur l’OHRQoL et d’évaluer la stabilité de l’effet de traitement dans le temps, tout en prenant en considération le niveau du SOC. MÉTHODOLOGIE: Des participants édentés (n=172, âge moyen 71, SD = 4.5) ayant reçu des CDs ou des IODs ont été suivis sur une période de deux ans. L’OHRQoL a été évaluée à l’aide du questionnaire « Oral Health Impact Profile (OHIP -20) » et ce avant le traitement et à chacun des deux suivis. Le SOC a été évalué à l’aide du questionnaire « The Orientation to Life (SOC -13) » à chacun des deux suivis. Des analyses statistiques ont été effectuées pour évaluer les différences intra et entre groupes (analyses statistiques descriptives, bivariées et multivariées). RÉSULTATS: Une amélioration statistiquement significative de l’OHRQoL entre les statuts avant et après traitement a été notée dans les deux groupes (Wilks’s Lambda = 0.473, F (1,151) = 157.31, p < 0.0001). L’amplitude de l’effet du traitement IOD est 1.5 fois plus grande que celle du traitement CD. Ces résultats ont été stables pendant les deux années d’étude et ils n’ont pas été influencés par le SOC. CONCLUSION: Le traitement IOD amène une meilleure OHRQoL à long terme en comparaison avec le traitement CD et ce sans influence du niveau du SOC. Ces résultats sont cliniquement significatifs et confirment la supériorité des IODs sur les CDs.
