During the early phase of treatment, there is an acute reduction in WM FA that may be due to the effects of antipsychotic medications. However, it is not possible to entirely exclude the effects of underlying progression of illness.

VAI could independently predict DM in the Chinese study population, although the predictive power was not higher than that of simple anthropometric measures (BMI and WC). Our study does not support the clinical application of VAI; however, more studies based on different ethnic groups still need to be performed.

The aim of this study is to compare the survival time and quality of life (QOL) of patients who have received different treatment for tracheoesophageal/bronchoesophageal fistula. Between January 2003 and December 2007, 35 patients with malignant tracheoesophageal/bronchoesophageal fistula were recorded as the control group, gastrostomy group, and stenting group, respectively, according to the treatments they chose. Two weeks after the treatment, European Organization for Research and Treatment of Cancer Quality of Life Core 30 Questionnaire (QLQ-C30), Quality of Life Questionnaire-esophageal module (QLQ-OES18), and a respiratory symptom-related QOL index are employed to assess QOL of these patients. There is no significant difference in survival time and constituent ratio of death reason among groups. Except for eight patients who died within 2 weeks after the treatment, all other 27 patients returned back the questionnaires. As compared to the control group, patients in the gastrostomy group gained a low score in emotional function and financial situation, while patients in the stenting group had lower scores in financial problems and seven respiratory and eating-related symptoms. In contrast with the gastrostomy group, patients in stenting group had higher scores in emotional and social functions, and lower scores in six respiratory and eating-related symptoms. With patients' QOL considered, the self-expandable coated stenting should be the first choice of therapy for malignant tracheoesophageal/bronchoesophageal fistula, whereas gastrostomy should be kept from use.

This meta-analysis suggests that there is an increased risk of ATDH in individuals carrying the C1/C1 genotype of the CYP2E1 RsaI/PstI polymorphism. However, no association was found for the DraI polymorphism.
