Meta Analysis Observational Study
eNOS Genetic Polymorphisms and Cancer Risk: A Meta-Analysis and a Case-Control Study of Breast Cancer.
The association between endothelial nitric oxide synthase (eNOS) polymorphisms (intron 4a/b, -786T>C and 894G>T) and cancer risk remains elusive. In addition, no studies focused on their associations with the risk of breast cancer in Chinese Han population. Thus, a meta-analysis was conducted to determine the relationship between eNOS polymorphisms and cancer risk, and then a case-control study in Chinese Han population was performed to assess their associations with breast cancer susceptibility. ⋯ In addition, stratified analyses based on pathological type showed that eNOS 894G>T polymorphism was only associated with the risk of infiltrative ductal carcinoma. Stratified analyses by tumor stage showed that eNOS -786T>C polymorphism was only associated with the risk of tumor stage III and IV. In conclusion, our meta-analysis and case-control study suggest that eNOS -786T>C and 894G>T polymorphisms are associated with the increased risk of breast cancer.

Meta Analysis
Association of CYP1A1 and GSTM1 Polymorphisms With Oral Cancer Susceptibility: A Meta-Analysis.
Our meta-analysis was aimed to evaluate the association of CYP1A1 and glutathione-S-transferase M1 (GSTM1) polymorphisms with oral cancer susceptibility. The related articles were searched in PubMed, Embase, and CNKI databases. Fifty eligible studies were included in our meta-analysis. ⋯ Moreover, the analysis based on source of control suggested that rs4646903 could increase the risk for oral cancer in both population- and hospital-based populations, whereas no remarkable relationship of rs1048943 with oral cancer susceptibility was observed. For GSTM1 gene, null genotype appeared to be a risk factor for oral cancer (null vs present: OR 1.23, 95% CI 1.12-1.34), which was also proved in the subgroup analysis. The results demonstrated that CYP1A1 rs4646903 and null genotype of GSTM1 polymorphisms might serve as risk factors for oral cancer.

Observational Study
Emergency Presentations With Nonspecific Complaints-the Burden of Morbidity and the Spectrum of Underlying Disease: Nonspecific Complaints and Underlying Disease.
The prevalence of diagnoses, morbidity, and mortality of patients with nonspecific complaints (NSC) presenting to the emergency department (ED) is unknown. To determine the prevalence of diagnoses, acute morbidity, and mortality of patients with NSC. Prospective observational study with a 30-day follow-up. ⋯ Acute morbidity and mortality were high in the presented cohort, the predictors of morbidity and mortality being age and sex rather than the nature of the complaints. Urgently needed management strategies could be based on these results. ClinicalTrials.gov (#NCT00920491).

A retrospective study. To summarize and describe the radiographic parameters of adult degenerative scoliosis (ADS) and explore the radiological parameters which are significantly different in sagittal balanced and imbalanced ADS patients. ADS is the most common type of adult spinal deformity. ⋯ Our study provided the general radiographic parameters of ADS. Weak or moderate but significant correlations between coronal Cobb angle and curve segments and degree of apical vertebra rotation were observed. Furthermore, age, coronal Cobb angle, LL, PT, and PI-LL were significantly different between sagittal balanced and imbalanced ADS patients.

Frequent emergency department (ED) users contribute to a disproportionate number of ED visits that consume a substantial amount of medical resources. Additionally, people with frequent ED visits may be at greater risks of illnesses and injury and are vulnerable to even more severe health events. We conducted, based on a nationally representative sample, a population-based study to estimate the prevalence of frequent ED users among all ED users, and to explore factors associated with frequent ED visits. ⋯ On the contrary, the significant predictors for highly frequent ED visit with greater AOR included hospitalization during the past year (AOR = 3.95), > 12 outpatient visits during the past year (AOR = 2.66), and a history of congestive heart failure (AOR = 2.64) and psychiatric disorders (AOR = 2.35). People admitted and with frequent outpatient visits were at greater risk of frequent ED visit. Because people with a history of various comorbidities were also vulnerable to become frequent ED users, careful management of those comorbidities by clinicians may help further reduce the likelihood of frequent ED visit.
