[Status and influencing factors of knowledge awareness and service acceptance of HIV non-occupational post-exposure prophylaxis of men who have sex with men among college students among three cities of China, 2019].

Objective: To understand the knowledge awareness and service acceptance of HIV non-occupational post-exposure prophylaxis (nPEP) men who have sex with men (MSM) among college students in three cities of China. Methods: Male college students in 10 universities of Beijing, Shenzhen and Kunming aged 18 and above who had sex with men in the last 3 months were recruited as research objects by cluster stratified sampling from March 15, 2019 to April 14, 2019.Basic information, sexual behavior characteristics, knowledge, and service acceptance of nPEP were collected through online questionnaire survey. Multivariate dichotomy and unconditioned logistic regression model was used to explore related factors about knowledge awareness and service acceptance of nPEP. Results: A total of 293 MSM were surveyed. The average age was (21.0±0.2) years old, and 91.1% (267) were undergraduates. In the last 3 months before the survey, 54.3%(159) used condom each time of sex; 4.4%(13) had intercourse with the HIV infected men, and 9.2% (27)suffered STDs in the past 6 months. The 29.4% (86) had not received HIV testing in the past year. The nPEP knowledge awareness rate was 47.8% (140). The 21.2% (62) counseled nPEP services, and 9.9% (29) received nPEP services. After multiple logistic regression analysis, compared with those who not received HIV testing in the past year, OR (95%CI) value of those who received HIV testing for more than twice in the past year to aware the nPEP knowledge was 3.15 (1.01-9.86). Compared with those who not received HIV testing in the past year, OR (95%CI) value of those who received HIV testing for more than twice in the past year to counsel the nPEP services was 5.29 (1.51-18.51). Compared with those who never used rush in the last 3 months, OR(95%CI) value of those who ever used rush in the last 3 months to receive the nPEP services was 3.86 (0.99-14.98). Compared with those who not sexed with HIV infected in the last 3 months, OR (95%CI) value of those who sexed with HIV infected in the last 3 months to receive the nPEP services was 14.30 (3.35-61.03). Conclusion: The proportions of awareness of nPEP knowledge and acceptance of nPEP services are low. MSM among college students need further health education of the nPEP knowledge to improve the accessibility of services.

Relationship between serum omentin-1 level and bone mineral density in girls with anorexia nervosa.

BACKGROUND: Adolescents with anorexia nervosa (AN) have low bone mineral density (BMD). Omentin- 1, the main circulating adipocytokine, plays an important role in bone metabolism in healthy individuals. However, their association with bone metabolism in AN is unknown. METHODS: Serum omentin-1, bone turnover biochemical markers, and BMD were determined in 26 girls with AN and 24 healthy girls (15-18 years old). RESULTS: Omentin-1 levels increased in AN subjects, and the differences became greater after controlling for fat mass. Omentin-1 was negatively correlated with BMD. In the multiple linear stepwise regression analysis, omentin-1, body mass index and lean mass, but not fat mass, were independent predictors of BMD for the combined group. Significant negative correlations were found between omentin-1 and bone-specific alkaline phosphatase, bone cross-linked N-telopeptides of type I collagen. Omentin-1 was also independently associated with BMD and bone turnover markers in the AN and control groups considered separately. CONCLUSIONS: Omentin-1 was an independent predictor of BMD in adolescents with AN, and negatively correlated with bone turnover markers. This suggested that omentin-1 may exert a negative effect on bone mass by inhibiting bone formation in girls with AN.

The infection status of anisakid larvae in marine fish and cephalopods from the Bohai Sea, China and their taxonomical consideration.

The infection status of anisakid larvae was examined in 290 marine fish of 25 species and in 108 cephalopods of 3 species purchased in Bayuquan region, Yingko city nearby the coast of the Bohai Sea from may to August 1992. A total of 7,327 larvae were collected from 156 fish of 19 species and 8 squids of one species. The 3rd-stage larvae of Anisakis simplex were collected from 121 fish (63.4%) of 15 species (N = 191) and from 8 squids (14.8%) of one species (N = 54), and they were total, 5,992 (81.8%). Out of remaining 1,335 larvae, 154 (2.1%) were classified as Thynnascaris type B from 23 fish of 4 species, 1,013 (13.8%) as Thynnascaris type C from 79 fish of 13 species. 164 (2.2%) as Hysterothylacium China type V from 20 fish of 4 species, 3 (0.04%) as Raphidascaris from 3 fish of 2 species and one was Pseudoterranova decipiens larva.

A study on the life-cycle and epidemiology of Pseudanoplocephala crawfordi Baylis, 1927.

A study of the life-cycle and epidemiology of Pseudanoplocephala crawfordi Baylis, 1927 is reported. Intermediate hosts are Tenebrio obscurus, T. molitor, Carpophilus dimidiatus and Tribolium castaneum. The first three species are new host records. Development in the intermediate host takes 1-1.5 months. The completion of the life-cycle takes 2-2.5 months. Surveys of intermediate hosts, pigs, humans and rats were carried out. In Rattus norvegicus, the prevalence was as high as 22%. Epidemiological factors and suggestions for control measures are discussed.
