Objective: The aim of this study is to re-evaluate the relationship between smoking and lung cancer. Methods: In order to clarify the relationship between cigarette smoking and lung cancer, a review and meta-analysis of appropriate studies with a total sample size of n = 48393 was conducted. The p-value was set to p < 0,05. Results: It was not possible to reject the null-hypothesis H0: without smoking no lung cancer. Furthermore, the null-hypothesis H0: No causal relationship between smoking and lung cancer was rejected. Conclusions: Compared to the results from previous studies, the results of this study confirm previously published results. According the results of this study, without smoking no lung cancer. Smoking is the cause of lung cancer. Keywords: Smoking, lung cancer, causal relationship

Objective: This systematic review assesses the causal relationship between Mycobacterium avium subspecies paratuberculosis (MAP) and Crohn's disease (CD). Methods:A systematic review and meta-analysis of some impressive PCR based studies is provided aimed to answer among other questions the following question. Is there a cause effect relationship between Mycobacterium avium subspecies paratuberculosis and Crohn's disease? The method of the conditio per quam relationship was used to proof the hypothesis whether the presence of Mycobacterium avium subspecies paratuberculosis guarantees the presence of Crohn's disease. In other words, if Crohn's disease is present, then Mycobacterium avium subspecies paratuberculosis is present too. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between Mycobacterium avium subspecies paratuberculosis and Crohn's disease. Significance was indicated by a p-value of less than 0.05. Results:The studies analyzed (number of cases and controls N=1076) were able to provide evidence that Mycobacterium avium subspecies paratuberculosis is a necessary condition (conditio sine qua non) and sufficient condition of Crohn's disease. Furthermore, the studies analyzed provide impressive evidence of a cause-effect relationship between Mycobacterium avium subspecies paratuberculosis and Crohn's disease. Conclusion:Mycobacterium avium subspecies paratuberculosis is the cause of Crohn's disease (k=+0.4435, p value < 0.0001).

<i>Fusobacterium nucleatum</i>—The Cause of Human Colorectal Cancer

Objective: Accumulating evidence indicates that the gut microbiome has an increasingly important role in human disease and health. Fusobacterium nucleatum has been identified in several studies as the leading gut bacterium which is present in colorectal cancer (CRC). Still it is not clear if Fusobacterium plays a causal role. Methods: To explore the cause-effect relationship between Fusobacterium nucleatum and colorectal cancer, a systematic review and re-analysis of studies published were performed. The method of the conditio sine qua non relationship was used to proof the hypothesis without Fusobacterium nucleatum infection, no colorectal cancer. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause-effect relationship between Fusobacterium nucleatum and colorectal cancer. Significance was indicated by a p-value of less than 0.05. Result: The data analyzed support the Null-hypothesis that without Fusobacterium nucleatum infection, no colorectal cancer. In the same respect, the studies analyzed provide highly significant cause-effect relationship between Fusobacterium nucleatum and colorectal cancer. Conclusion: The findings of this study suggest that Fusobacterium (nucleatum) is the cause of colorectal cancer.
