Another thing is to realize that the study compares different sites of infection and different bacterias. So, if I begin with polimyxin and just after 3 days add amikacin, this guy who recive amikacin is the same that our 5th day drunk guy.

The only group which received polymyxin at adequate dose was the VCT group. The median of adequate treatment for monotherapy group was ZERO!

There it is, nebulized and intravenous are the same? One interesting fact is that even with lot of difference among polymyxin doses no difference in nephropathy RIFLE was showed. Nothing but the whole truth. Is that honest to compare this group with others? Data and results Patients in the validated polymyxin combination therapy had more severe infections and more serious disease, monotherapy group was older.

Therefore, beer drinkers have lower mortality than sober patients. Combination therapy for non-believers, and believers too!

Therefore, if you read an article showing a possible association between combined therapy and lower mortality and take this as true I can recommend you two books Statistics for Dummies, by Deborah Rumsey and if you can read in portuguese: In their majority, the most cited, are observational trials.


Meaning, if you wanna fihlo them, do it with the right dose! Take another look at the antibiotics doses table. Keep this in mind! Go hit the books then. This is gonna be a revolving theme here, so keep your eyes open! Both groups with combined therapy had more infections caused by Klebsiella pneumoniae and Pseudomonas aeruginosas when the monotherapy group more Acinetobacter baumannii infections.

The ART trial and how lung recruitment died. Is bioextatistica HCAP concept a lie? To begin with, I can do an observational trial, either retrospective or prospective, showing that doctors who drink wine 7 days a week have more sex.

Combination therapy for non-believers, and believers too!

Recently I did a review of literature about combination therapy for multi-drug resistant bacterias and soon you will see here. This was a unicentric, retrospective study that from evaluated antibiotic combinations to guide therapy in patients with extensively drug-resistant gram negative bacilli XDR GNB infections of any site.

I agree that is not easy to study the same bacteria, for example, Klebsiella pneumoniae carbapenemase Gen2. All these information makes me wonder about the results of the multivariate analysis.

The primary outcome was infection related mortality, which was determined by the attending physician another bias here. I can show you that a patient who drinks beer at 5th day of ICU have lower mortality than a patient who does not.

Moving on… The eligible patients were divided in three groups: S Army — Delta associates — Memegenerator. The antibiotic dose was included in the multivariate model. Why I hate tramadol but sometimes use it. And also other strange things happened. Bioestatixtica after a multivariate analysis the authors throw the results saying the risk of infection related mortality is 8x greater in MT group and 6x greater in NVCT group when compared to VCT group.


Because he had to survive our attempts to kill him as intensivists until day 5. Patients were included if: For me the idea of using intrduo doses to avoid adverse affects might increase bacterial resistance. Here we have a problem, Immortal Time Bias. Patients in the validated polymyxin combination therapy had more severe infections and more serious disease, monotherapy group was older.

Interestingly, was considered polymyxin use any of: Now, to study Klebsiella pneumoniae carbapenemase Gen2 causing blood stream infection and compare between monotherapy vs combined therapy?

From a statistical point of view, the drinker only begin to exist at day Even if the patients in the VCT group were more sick, it was the only group which received adequate dose treatment. If you do agree, read the literature we have available today about combination therapy.
