COVID‐19 diagnosis does not rule out other concomitant diseases

Darwinian evolution does not rule out the gaia hypothesis.

This study explores so-called Darwinian Daisyworlds mathematically rigorously in detail. The original Daisyworld was introduced by Watson & Lovelock (1983) to demonstrate how two species of daisies regulate the global temperature of their planet through competition among these species against the rising solar luminosity, i.e. the Gaia hypothesis. Its variants are Darwinian Daisyworlds in which ...

Stroke prevention: age alone does not rule out warfarin.

The pulmonary embolism rule-out criteria (PERC) rule does not safely exclude pulmonary embolism.

BACKGROUND The Pulmonary Embolism Rule-out Criteria (PERC) rule is a clinical diagnostic rule designed to exclude pulmonary embolism (PE) without further testing. We sought to externally validate the diagnostic performance of the PERC rule alone and combined with clinical probability assessment based on the revised Geneva score. METHODS The PERC rule was applied retrospectively to consecutive...

[Normal conventional electrocardiogram with negative pharmacological stress test does not rule out Brugada syndrome].

The diagnosis of Brugada syndrome, or right bundle-branch block with an elevated ST segment and negative T waves in V1-3, is obscured by the transitory normalization of the electrocardiogram, which can be unmasked by administering sodium-channel blockers. It has been recently reported that the condition can be underdiagnosed if only conventional precordial leads are used. We present the cases o...

Luria-Delbrück, revisited: the classic experiment does not rule out Lamarckian evolution.

We re-examined data from the classic Luria-Delbrück fluctuation experiment, which is often credited with establishing a Darwinian basis for evolution. We argue that, for the Lamarckian model of evolution to be ruled out by the experiment, the experiment must favor pure Darwinian evolution over both the Lamarckian model and a model that allows both Darwinian and Lamarckian mechanisms (as would h...
