Randomized Controlled Trial Comparative Study
Bupivacaine with meperidine versus bupivacaine with fentanyl for continuous epidural labor analgesia.
To compare the efficacy of bupivacaine-meperidine and bupivacaine-fentanyl mixtures when continuously infused epidurally to relief the labor pain. ⋯ Bupivacaine-meperidine in a continuous epidural infusion is as efficient as bupivacaine-fentanyl for pain relief during labor, but associated with a higher incidence of nausea and vomiting.

Comparative Study
Comparison of arterial and venous blood gases analysis in patients with exacerbation of chronic obstructive pulmonary disease.
To investigate whether venous blood gases (VBG) test can be replace by an arterial blood gases (ABG) in exacerbation of chronic obstructive pulmonary disease (COPD). ⋯ Venous blood gases, especially pH and PCO2 levels have relatively good correlation with ABG values. In view of the fact that, this correlation is not close, VBG cannot be substitute for ABG in exacerbation of COPD.

Editors of many established journals have noticed throughout the years an increase in the number of authors per article. I wish to put this theory to rest by calculating this linear increase for several prestigious journals. ⋯ The data collection and calculation method can be used for any journal indexed in PubMed. The resulting trends are likely due to the increasing complexity of research, the increasing pressure on researchers to publish or perish, among others. This paper, however, focuses less on the reasons for this trend and more on the computerized methods used to obtain the results.
