Abstract Background Gout stems from both modifiable and genetic sources. We evaluated the risk of gout among Taiwanese adults with aldehyde dehydrogenase-2 (ALDH2) rs671 single nucleotide polymorphism (SNP) according to body mass index (BMI) and alcohol drinking. Methods We obtained information of 9253 individuals having no personal history of cancer from the Taiwan Biobank (2008–2016) and estimated the association between gout and independent variables (e.g., rs671, BMI, and alcohol drinking) using multiple logistic regression. Results Alcohol drinking and abnormal BMI were associated with a higher risk of gout whereas the rs671 GA+AA genotype was associated with a lower risk. The odds ratios (ORs) and 95% confidence intervals (CIs) were 1.297 and 1.098–1.532 for alcohol drinking, 1.550 and 1.368–1.755 for abnormal BMI, and 0.887 and 0.800–0.984 for GA+AA. The interaction between BMI and alcohol on gout was significant for GG (p-value = 0.0102) and GA+AA (p-value = 0.0175). When we stratified genotypes by BMI, alcohol drinking was significantly associated with gout only among individuals with a normal BMI (OR; 95% CI = 1.533; 1.036–2.269 for GG and 2.109; 1.202–3.699 for GA+AA). Concerning the combination of BMI and alcohol drinking among participants stratified by genotypes (reference, GG genotype, normal BMI, and no alcohol drinking), the risk of gout was significantly higher in the following categories: GG, normal BMI, and alcohol drinking (OR, 95% CI = 1.929, 1.385–2.688); GG, abnormal BMI, and no alcohol drinking (OR, 95% CI, = 1.721, 1.442–2.052); GG, abnormal BMI, and alcohol drinking (OR, 95% CI = 1.941, 1.501–2.511); GA+AA, normal BMI, and alcohol drinking (OR, 95% CI = 1.971, 1.167–3.327); GA+AA, abnormal BMI, and no alcohol drinking (OR, 95% CI = 1.498, 1.256–1.586); and GA+AA, abnormal BMI, and alcohol drinking (OR, 95% CI = 1.545, 1.088–2.194). Conclusions Alcohol and abnormal BMI were associated with a higher risk of gout, whereas the rs671 GA+AA genotype was associated with a lower risk. Noteworthy, BMI and alcohol had a significant interaction on gout risk. Stratified analyses revealed that alcohol drinking especially among normal-weight individuals might elevate the risk of gout irrespective of the genotype.

Phylogeography has recently become more abundant in studies of demographic history of both wild and domestic species. A single nucleotide polymorphism (SNP) in the intron of the Y-chromosomal gene UTY19 displays a north–south gradient in modern cattle. Support for this geographical distribution of haplogroups has previously also been seen in ancient cattle from Germany. However, when analysing 38 historic remains of domestic bulls and three aurochs from northern Europe for this SNP we found no such association. Instead, we noted extensive amounts of temporal variation that can be attributed to transportation of cattle and late breed formation.

Introduction: Although considerable research describes the cardiovascular effects of habitual moderate and heavy alcohol consumption, the acute risks following alcohol intake have not been well characterized. Based on its physiological effects, alcohol may have markedly different effects on acute and long-term risk. We assessed the hypothesis that moderate alcohol consumption is associated with an immediately higher risk of cardiovascular events that becomes protective after 24 hours, whereas heavy alcohol drinking is associated with higher cardiovascular risk both immediately and in the following days. Methods: We searched CINAHL, Embase, PubMed and PsycINFO from inception to March 12 2015, supplemented with manual screening for observational studies assessing the association between alcohol intake and cardiovascular events in the following hours and days. We calculated pooled relative risks (RRs) and 95% confidence intervals (CIs) for the association between alcohol intake and myocardial infarction (MI), ischemic stroke (IS) and hemorrhagic stroke (HS) using DerSimonian and Laird random-effects models to model any alcohol intake or dose-response relationships of alcohol intake and cardiovascular events. Results: Among 1056 citations and 37 full-text articles reviewed, 23 studies (29457 participants) were included. Moderate alcohol consumption was associated with an acutely higher cardiovascular risk that was attenuated after 24 hours and even protective for MI and HS (≈2-4 drinks: RR=30% lower risk), and protective against IS within one week (≈6 drinks: RR=19% lower risk). In contrast, heavy alcohol drinking was associated with higher cardiovascular risk in the following day (≈6-9 drinks: RR=1.3-2.3) and week (≈19-30 drinks: RR=2.25-6.2). Conclusions: In conclusion, there appears to be a consistent finding of an acutely higher cardiovascular risk following any alcohol consumption but by 24 hours, only heavy alcohol intake conferred continued risk.

AbstractOutbreaks of tuberculosis- such as the large isoniazid-resistant outbreak centered on London, United Kingdom, which originated in 1995- provide excellent opportunities to model transmission of this devastating disease. Transmission chains for tuberculosis are notoriously difficult to ascertain, but mathematical modelling approaches, combined with whole-genome sequencing (WGS) data, have strong potential to contribute to transmission analyses. Using such data, we aimed to reconstruct transmission histories for the outbreak using a Bayesian approach, and to use machine learning techniques with patient-level data to identify the key covariates associated with transmission. By using our transmission reconstruction method that accounts for phylogenetic uncertainty, we are able to identify 24 transmission events with reasonable confidence, 11 of which have zero single nucleotide polymorphism (SNP) distance, and as maximum distance of 3. Patient age, alcohol abuse and history of homelessness were found to be the most important predictors of being credible tuberculosis transmitters.

The purpose of the current study is to explore the contribution of single-nucleotide polymorphisms (SNPs) of REX1 rs6815391, OCT4 rs13409 or rs3130932, and CTBP2 rs3740535 to the risk of lung cancer. A questionnaire survey was used to obtain basic information of the included subjects. A case control study was performed in 1121 patients and 1121 controls. All subjects were subjected to blood sampling for genomic DNA extraction and genotyping of the cancer stem cell-associated gene SNPs, including REX1 rs6815391, OCT4 rs13409 or rs3130932, and CTBP2 rs3740535 by real-time PCR. The association with the risk of primary lung cancer and interaction with environmental factors were assessed using unconditional logistic regression for the odds ratios and corresponding 95% confidence intervals. The genotype frequency distribution of OCT4 rs13409 loci was statistically significant, but there was no significant difference in the rest of the loci between lung cancer patients and healthy controls. The OCT4 gene was also related with lung cancer susceptibility in the genetic model after adjusting for lung cancer-related factors. Despite the presence of the dominant or recessive model, the four loci polymorphisms were associated with pollution near the place of residence, house type, worse ventilation situation, smoking, passive smoking, cooking oil fumes (COF), and family history of cancer, which increased the risk of lung cancer. Nonmarried status, 18.5≤BMI, COF, smoking, passive smoking, family history of cancer, and history of lung disease were independent risk factors of lung cancer susceptibility. Additionally, college degree or above, no pollution near the place of residence, protective genotype 1 or 2, and well ventilation can reduce the occurrence of lung cancer. There is an interaction between the four loci and environmental factors, and OCT4 rs13409 is a risk factor of primary lung cancer.

Background & Aims: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas have been reported to be associated with an increased risk of developing extra-pancreatic malignancies. A common genetic background has been hypothesised to be responsible for such an association. Human chromosomal region 8q24 has been associated with many types of cancer. The majority of these associations lie at approximately 128 Mb on chromosome 8. We conducted a study in order to examine the association between IPMN and single nucleotide polymorphisms (SNPs) from the 8q24 region, namely rs10505477, rs6983267, rs7014346, rs6993464, previously reported to influence general cancer susceptibility. Methods. The study was performed on 117 IPMN cases and 231 controls. Cases were enrolled at the Digestive Endoscopy Unit, Policlinico Agostino Gemelli from January, 2010 to June, 2011, with either a prevalent or incident IPMN diagnosis. Status of SNPs was determined using a StepOne Real-time PCR system (Applied Biosystems) and TaqMan SNP Genotyping Assay™ 40X. Unconditional multiple logistic regression models were used to estimate odds ratios and 95% confidence intervals for the association of selected SNPs and IPMNs. Results. Cases were more likely to report a 1st degree family history of cancer (p<0.001), as well as heavy smoking (p=0.001) and heavy drinking habits (p<0.001). No significant association was observed between IPMN and selected SNPs. The results were confirmed also when stratified according to any 1st-degree family history of cancer. Conclusion. Patients with IPMN do not have a higher prevalence of SNPs in the human chromosomal region 8q24 in respect to the control population.
