Objectives: To clarify the awareness and source of AIDS knowledge among college students of medical university of Guizhou province, China, so as to provide some basic evidences for implementing education of AIDS control and prevention.

Methods: A stratified cluster sampling survey was conducted. Self-designed questionnaires were used to investigate university students, Epidata 3.0 and SPSS 18.0 were used to analyze data.

Results: The awareness rate of AIDS through blood transmission and mother-to-child transmission was over 90%, the awareness rate of sexual transmission was just about 80%, and the awareness rate of non- transmission route “mosquito bites will not spread AIDS” was only 53.3%. The awareness rate of AIDS transmission and treatment among medical students was higher than that of non-medical students. The Internet, propaganda materials, newspapers and magazines, and school classes were the main ways for university students to acquire AIDS knowledge. Some students hope to acquire knowledge from classmates and friends, it was found that the proportion of medical students receiving AIDS knowledge from school classes was significantly higher than that of non-medical students (80.8% vs. 73.1%, p =.007).

Conclusion: Though the awareness rate of AIDS knowledge among medical students is better than that of non-medical students, they had insufficient knowledge of AIDS, especially the sexual transmission. Moreover, school classes may be an effective way to propagandize AIDS-related knowledge, so schools can consider publicizing the AIDS education through classes, so as to improve students’ abilities of AIDS control and prevention.

The viruses of the Paramyxoviridae family are known to infect a wide range of animals, including primates, birds, rodents, carnivores, bats, ungulates, snakes, cetaceans and humans. This study aims to investigate the circulation of paramyxoviruses in five potential host species groups (humans, non-human primates, rodents, shrews, and bats) living in the same environments in three conservation programs dedicated to non-human primates, namely the Lékédi park, the primatology center of the International Center for Medical Research of Franceville and the Gorilla Protection Program, located in Gabon. We tested 35 workers, 343 NHPs (8 species), 141 bats (4 species), 420 rodents (5 species) and 10 shrews, sampled between 2013 and 2014. Faecal and organ samples were analyzed using three heminested reverse transcription-PCR (hnRT-PCR). All the 1884 samples tested were negative for PV detection. Further studies spanning a greater period of time are needed to investigate PV circulation patterns in these conservation programs.

Objectives: To investigate the epidemiological characteristics and morbidity of the snake-bite injury in Zunyi city, China, so as to provide the first aid guidance and public education for the prevention and treatment strategies of snake-bite injuries.

Methods: A cross-sectional study was conducted, and 548 cases of snake-bite were observed in this study between January 1, 2015 to December 31, 2017. They were identified form the Emergency Department of the Affiliated Hospital of Zunyi Medical University. A retrospective epidemiological survey was conducted to collect their information on sex, age, occupation, bite location, bite year and season, specific bite cause.

Results: The number of the patients of snake-bite was increased; however, the fatality rate gradually was decreased year by year during the investigating period. Seven patients died during year 2015-2017 and the 3-year total mortality was 2.9%. Among the dead, 59.31% were male and 40.69% were female. 19.70% of patients were between 41 and 50 years old, 17.70% were between 51 and 60 years and 16.79% of patients were between 61 and 70 years old. Moreover, 66.97% of patients were on the lower extremity and 31.93% of patients on the upper extremity. 83.39% of patients were bitten while farming and 12.04% of patients were bitten while walking. Most cases occurred during summer and autumn (7-9 months) seasons. The regional distributions of 548 snake-bites were 44.34% in the County and 33.94% in districts of Zunyi city.

Conclusion: Target preventive measures should be conducted in high risk populations in Zunyi city, especially in spring and summer.

Background: We evaluated women with a prior cesarean delivery (CD) who were eligible for elective repeat CD or trial of labor to test whether the risk of severe maternal morbidity (SMM) was: 1) directly associated with important pre-existing and gestational conditions or 2) indirectly associated (significantly increased or decreased) with the decision to undergo elective repeat CD.

Methods: Women with a prior CD who had inborn, liveborn, term, singleton, vertex deliveries were identified in California 2010-2011 hospital discharge datasets. Using discharge codes, this population was stratified into two groups: attempted labor and elective repeat CD. A mediation model (stratified by younger vs. older women [>35 years]) was built for each of the following maternal conditions (exposure): chronic/gestational diabetes mellitus (DM), chronic/gestational hypertension, heart disease, obesity, and mental health diagnoses. Elective repeat CD was the mediator and SMM was the outcome.

Results: Of 141,535 eligible deliveries, 72.7% had an elective repeat CD; 2.3% had SMM, which occurred in 2.2% of younger vs. 2.6% of older women. For younger and older women respectively, the modeled total effect odds ratios (95% CI) for heart disease were: 10.7 (8.5, 13.5) and 8.8 (6.4, 12.2); for hypertension: 1.7 (1.4, 1.9) and 2.0 (1.6, 2.4); and for mental health diagnoses: 1.9 (1.6, 2.3) and 1.7 (1.3, 2.3). Neither DM nor obesity demonstrated a direct effect. Odds ratios for indirect effects were negligible for all models.

Conclusion: Among women with a prior CD, in the presence of important health conditions, the increased risk of SMM mediated by an elective repeat CD was negligible.

Objective: To assess the prevalence of left ventricular hypertrophy (LVH) and linked cardiovascular risk factors in civilian aircrew.

Methods: Cardiovascular risk factors were assessed among flight and cabin crew undergoing routine clinical and biological evaluation for initial or renewal of aeromedical license. The evaluation also included a standard 12-lead ECG and echocardiography. Echo-based LVH was LVM ≥ 49 g/m^2.7 (men) or ≥ 45 g/m^2.7 (women). LVH was categorized as mild (men: 49-55 g/m^2.7; women: 45-51 g/m^2.7), moderate (men: 56-63 g/m^2.7; women: 52-58 g/m^2.7), or severe (men: ≥ 64 g/m^2.7; women: ≥ 59g/m^2.7) according to Lang’s report.

Results: Among the 379 aircrew members (70.4% men; 23% Caucasians; 62.5% flight crew; mean age 40.6 ± 12.8 years), LVH was present in 36 individuals (9.5%) with mild, moderate and severe pattern observed respectively in 19.4%, 33.3% and 47.2% of the cases. The rate of LVH amounted to 16.7% in normotensive subjects, 25.0% in those with prehypertension, and 58.3% among hypertensive individuals. In addition to age of 40-59y (OR: 8.48; 95% CI: [2.23-12.23]; p =.002) or more (4.22 [1.57-11.35]; p =.004), hypertension (3.55 [1.50 - 8.41]; p =.004), overweight/obesity (5.33 [1.14 - 25.05]; p =.034) and hyperuricemia (5.05 [2.11 - 12.09]; p =.001), all well-known constituents of the metabolic syndrome, were the main factors significantly associated with LVH.

Conclusion: The frequency and link of LVH to the components of the metabolic syndrome highlights the need for a comprehensive approach to the management of cardiovascular risk factors in civilian aircrew.

Introduction: Church-based interventions improve weight-related outcomes among underserved populations. African Americans, particularly young to middle age adults, are seldom represented in the literature and are key health intervention targets to prevent obesity-related chronic disease. Thus, the objective of this study was to describe the lessons learned from comparing the intervention outcomes of a two-phase, weight management intervention targeting younger to middle aged adult African Americans in Mississippi.

Methods: A weight management intervention was tested and data were collected over two phases using the Bridge2U platform. Descriptive methods examined retention and attendance rates, and anthropometric and demographic data; Wilcoxon signed-rank and Fisher’s exact tests examined group differences in pre and post outcomes.

Results: Attendance rates were 39.9 and 55.4% for phases 1 and 2, respectively. Differences were noted between those who dropped out of the phase 1 intervention and those who remained. Weight loss was significant at 5.6 and 4.8% of baseline body weight for phases 1 and 2, respectively. Significant changes were also noted among other variables.

Conclusions: Disease diagnosis, more intensive intervention format and technology-assisted delivery may be key factors for improved participation and engagement of young to middle aged African Americans in weight management interventions. This study provides future implications for weight management intervention and chronic disease prevention among young to middle aged adult African Americans in the Deep South.
