    <p>25 clones representing the first IR2 sequence part (blue bars; primer pair F/R-1.1, PCR product includes poly(T) stretch) and 17 clones representing the second IR2 sequence part (red bars; primer pair F/R-1.3, PCR product includes poly(A) stretch) were sequenced according to Sanger and analyzed. Since, the quality of the poly(A) sequences obtained had been suboptimal, the reverse complement sequences containing a poly(T) stretch instead of the poly(A) motif were analyzed. For both IR2 sequence parts investigated, variations in length due to the phenomenon of strand slippage were observed. Accordingly, it was not possible to determine the exact length of the poly(T) and the poly(A) stretches. Most likely, both homopolymeric sequence motifs are 18 or 19 bp in length.</p

    ObjectiveTo quantify and communicate risk equivalencies for alcohol-and tobacco-attributable mortality by comparing per standard drinks consumed to per number of cigarettes smoked in Canada.MethodsAlcohol-and tobacco-attributable premature deaths (≤75 years of age) and years of life lost (YLL) were estimated using a lifetime risk modeling approach. Alcohol-attributable death statistics were obtained from the 2023 Canadian Guidance on Alcohol and Health data source. Tobacco-attributable death statistics were derived from the Mortality Population Risk Tool (MPoRT) model.ResultsThe risk of alcohol use on premature death and YLL increased non-linearly with the number of drinks consumed, while the risk for tobacco use on these two measures increased linearly with the number of cigarettes smoked. Males who consumed 5 drinks/day—a standard drink contains 13.45 grams of alcohol in Canada—had an equivalent risk as smoking 4.9 cigarettes/day (when modeling for premature death) and 5.1 cigarettes/day (when modeling for YLL). Females who consumed 5 drinks/day experienced an equivalent risk as smoking 4.2 cigarettes/day for premature deaths and YLL. At all levels of alcohol consumption females and males who consumed ConclusionRisk equivalencies comparing alcohol use to tobacco use could help people who drink improve their knowledge and understanding of the mortality risks associated with increased number of drinks consumed per day.</p
