Green Tobacco Sickness (GTS) has been one of the unexplored areas of occupational health safety. The condition mainly affects the tobacco harvesters. The condition is prevalent in Asian and South American tobacco harvesters. Although transient, the condition can affect multiple organ systems. The objective of this review is to extensively discuss the background, epidemiology, clinical features and measures to counter the problem.A literature search of Medline with terms such as “green”, “tobacco” and “sickness” was done covering years 1970-2007. All studies, reviews and commentaries on health effects of farming green tobacco and preventing the disease were included.Green Tobacco Sickness is caused by the absorption of nicotine through the skin from wet tobacco plants who have direct contact with tobacco plants during cultivation and harvesting. The early symptoms often include headache and nausea followed by vomiting, weakness, pallor, dizziness, headaches, increased perspiration, chills, abdominal pain, diarrhoea, and increased salivation which may also progress to extreme conditions like prostration, shortness of breath, and occasional fluctuations in blood pressure or heart rate. The duration of the illness is usually between one and three days. The use of protective, water-resistant clothing, chemical-resistant gloves, plastic aprons and rainsuits with boots and socks has reduced the chances of contracting GTS.It is important to educate the tobacco workers and the employers about GTS in order to reduce its incidence. An international level awareness campaign has to be taken up and more stringent workers safety regulations have to be formulated.DOI: http://dx.doi.org/10.3126/ijosh.v2i1.4963 International Journal of Occupational Safety and Health, Vol. 2 No. 1 (2012) 11-14

Abstract Although hundreds of genome-wide association studies-implicated loci have been reported for adult obesity-related traits, less is known about the genetics specific for early-onset obesity and with only a few studies conducted in non-European populations to date. Searching for additional genetic variants associated with childhood obesity, we performed a trans-ancestral meta-analysis of 30 studies consisting of up to 13 005 cases (≥95th percentile of body mass index (BMI) achieved 2–18 years old) and 15 599 controls (consistently <50th percentile of BMI) of European, African, North/South American and East Asian ancestry. Suggestive loci were taken forward for replication in a sample of 1888 cases and 4689 controls from seven cohorts of European and North/South American ancestry. In addition to observing 18 previously implicated BMI or obesity loci, for both early and late onset, we uncovered one completely novel locus in this trans-ancestral analysis (nearest gene, METTL15). The variant was nominally associated with only the European subgroup analysis but had a consistent direction of effect in other ethnicities. We then utilized trans-ancestral Bayesian analysis to narrow down the location of the probable causal variant at each genome-wide significant signal. Of all the fine-mapped loci, we were able to narrow down the causative variant at four known loci to fewer than 10 single nucleotide polymorphisms (SNPs) (FAIM2, GNPDA2, MC4R and SEC16B loci). In conclusion, an ethnically diverse setting has enabled us to both identify an additional pediatric obesity locus and further fine-map existing loci.

Abstract Background The association of H. pylori babA2 gene with gastric cancer (GC) was proposed by several studies, but the results have been inconsistent. Objective of this meta-analysis was to investigate the association of Helicobacter pylori (H. pylori ) babA2 gene and gastric cancer (GC) risk.Methods Studies evaluated the association between H. pylori babA2 gene and GC risk were collected from PubMed databases. A meta-analysis of case-control studies was used. The pooled ORs with 95% CIs were used to calculate the effect of H. pylori babA2 gene effect on GC risk.Results Twenty studies were identified with a total of 747 GC and 1597 controls. Infection with H. pylori babA2 gene was associated with an increased risk of GC by 1.46 fold (95% CI: 1.19-1.77, P=0.001) . In subgroup analysis, borderline association was found among South American and strong association was found among Asian population, with pooled OR of 1.38 (95% CI: 0.97-1.95, P=0.068 ) and 1.50 (95% CI: 1.16-1.93, P=0.002 ) respectively.Conclusions This meta-analysis validated that H. pylori babA2 gene may be associated with increased risk of GC. And positive association was found among Asian population.

Abstract Purpose: Dietary carbohydrate intake had become recognized as an important risk factor for risk of esophageal cancer. This meta-analysis aimed to assess the association between dietary carbohydrate intake and the risk of esophageal cancer. Methods: Suitable databases were carefully searched. A random-effects model was used for combined the odds ratio (OR) and 95% confidence interval (CI). Stata software 14.0 was adopted for the analysis. Results: Thirteen publications were included in our study. There was significant correlation between highest category compared with lowest category of dietary carbohydrate intake and the risk of esophageal cancer (summarized OR= 0.627, 95%CI= 0.505-0.778, I2= 59.9%, P for heterogeneity = 0.001). The results in the subgroup of esophageal adenocarcinoma (summarized OR= 0.569, 95%CI= 0.417-0.777) and esophageal squamous cell carcinoma (summarized OR= 0.665, 95%CI= 0.453-0.975) were consistent with the overall result. A positive association was found in European populations, Asian populations, North American populations, instead of South American populations. Conclusions: In conclusions, dietary carbohydrate intake may have a protective effect against the risk of esophageal cancer.
