This research was aimed to explore correlation of gene polymorphisms of CD36 and ApoE with susceptibility of Alzheimer disease (AD). This study was a case-control study. Two hundred eleven AD hospitalized patients were selected as the AD group and 241 subjects were selected as the control group. ⋯ For ApoE gene, the distribution differences of E2/E3 (χ = 9.216, P = .002), E3/E4 (χ = 7.728, P = .005), and E4/E4 had statistical significance between the 2 groups. The frequencies of allele E2 (χ = 9.359, P = .002) and E4 (χ = 13.995, P < .001) were statistically significant between AD and control groups. The rs7755 and rs3211956 loci polymorphisms of CD36 gene and genotype E2/E3, E3/E4, E4/E4 of ApoE gene, and E2 and E4 alleles were statistically related with AD.

The incidence rate of nasopharyngeal cancer (nasopharyngeal carcinoma [NPC]) is much higher in Southeast Asia than in western countries. Interleukin-8 (IL-8), a chemokine produced by macrophages, epithelial cells, airway smooth muscle cells, and endothelial cells, is an important immuno-mediator in the development and progression of many types of cancer. Genetic variations in IL-8 have been associated with the risks of NPC and other cancers. ⋯ Regarding the IL-8 promoter T - 251A, the TA and AA genotypes were associated with significantly decreased risks of NPC compared with the wild-type TT genotype (adjusted odds ratio = 0.61 and 0.52, 95% confidence interval = 0.47-0.93 and 0.37-0.91, P = .0415 and .0289, respectively). The mRNA and protein expression levels for NPC tissues revealed no significant associations among the 20 NPC samples with different genotypes. These findings suggest that IL-8 may play an important role in the carcinogenesis of NPC in Taiwan.

Associations of race, mechanism of injury, and neighborhood poverty with in-hospital mortality from trauma: A population-based study in the Detroit metropolitan area.
Health disparities based on race and socioeconomic status are a serious problem in the US health care system, but disparities in outcomes related to traumatic injury have received relatively little attention in the research literature. This study uses data from the State Inpatient Database for Michigan including all trauma-related hospital admissions in the period from 2006 to 2014 in the Detroit metropolitan area (N = 407,553) to examine the relationship between race (White N = 232,109; African American N = 86,356, Hispanic N = 2709, Other N = 10,623), socioeconomic background, and in-hospital trauma mortality. Compared with other groups, there was a higher risk of mortality after trauma among African Americans (odds ratio [OR] = 1.20, P < .001), people living in high-poverty neighborhoods (OR = 1.01, P < .001), and those enrolled in public health insurance programs (OR = 1.53, P < .001). ⋯ After controlling for mechanism alone in multiple logistic regression, African American race remained a significant predictor of mortality risk (OR = 1.12, P < .001). After additionally controlling for the socioeconomic factors of insurance status and neighborhood poverty levels, there were no longer any significant differences between racial groups in terms of mortality (OR = 0.99, P = .746). These results suggest that in this population the racial inequalities in mortality outcomes were fully mediated by differences between groups in the pattern of injuries suffered and differences in risk based on socioeconomic factors.

To evaluate the clinical outcomes of an anterolateral approach for lateral humeral condylar fractures in children. The patients aged < 15 years undergoing surgery with an anterolateral approach for humeral lateral condylar fractures between April 2005 and March 2014 were investigated. Medical records and radiographs from 15 patients were reviewed. ⋯ Based on Flynn criteria, clinical results for both cosmetics and function were excellent in 13 patients, and good in 2. The advantages of the anterolateral approach are combining an optimal view of the anterior articular surface of the trochlea and capitellum and a limited risk of devascularization injury. We strongly recommend an anterolateral approach for these fractures in children to prevent postoperative deformity and to achieve anatomical reduction and reliable fixation.

Traumatic brain injury is a leading cause of death and disability worldwide. The survivors usually suffer from disorders of consciousness, especially coma state and persistent vegetative state. For these patients, there is no standard treatment for them, but non-invasive brain stimulations are considered as relatively more acceptable treatments. However, the knowledge regarding the relative effectiveness and the rank of the effectiveness of the non-invasive brain stimulations is limited. Thus, in this study, we aim to conduct a systematic review and network meta-analysis to evaluate the effect of non-invasive train stimulations on arousal and alertness in patients in a coma or persistent vegetative state after traumatic brain injury. ⋯ CRD42018104945.
