Objective To compare results of different methods in organizing HIV viral load (VL) data with missing values mechanism. Methods We used software SPSS 17.0 to simulate complete and missing data with different missing value mechanism from HIV viral loading data collected from MSM in 16 cities in China in 2013. Maximum Likelihood Methods Using the Expectation and Maximization Algorithm (EM), regressive method, mean imputation, delete method, and Markov Chain Monte Carlo (MCMC) were used to supplement missing data respectively. The results of different methods were compared according to distribution characteristics, accuracy and precision. Results HIV VL data could not be transferred into a normal distribution. All the methods showed good results in iterating data which is Missing Completely at Random Mechanism (MCAR). For the other types of missing data, regressive and MCMC methods were used to keep the main characteristic of the original data. The means of iterating database with different methods were all close to the original one. The EM, regressive method, mean imputation, and delete method under-estimate VL while MCMC overestimates it. Conclusion MCMC can be used as the main imputation method for HIV virus loading missing data. The iterated data can be used as a reference for mean HIV VL estimation among the investigated population.

Objective To understand the distribution of population viral load (PVL) data in HIV infected men who have sex with men (MSM), fit distribution function and explore the appropriate estimating parameter of PVL. Methods The detection limit of viral load (VL) was ≤ 50 copies/ml. Box-Cox transformation and normal distribution tests were used to describe the general distribution characteristics of the original and transformed data of PVL, then the stable distribution function was fitted with test of goodness of fit. Results The original PVL data fitted a skewed distribution with the variation coefficient of 622.24%, and had a multimodal distribution after Box-Cox transformation with optimal parameter (λ) of-0.11. The distribution of PVL data over the detection limit was skewed and heavy tailed when transformed by Box-Cox with optimal λ=0. By fitting the distribution function of the transformed data over the detection limit, it matched the stable distribution (SD) function (α=1.70, β=-1.00, γ=0.78, δ=4.03). Conclusions The original PVL data had some censored data below the detection limit, and the data over the detection limit had abnormal distribution with large degree of variation. When proportion of the censored data was large, it was inappropriate to use half-value of detection limit to replace the censored ones. The log-transformed data over the detection limit fitted the SD. The median (M) and inter-quartile ranger (IQR) of log-transformed data can be used to describe the centralized tendency and dispersion tendency of the data over the detection limit.

OBJECTIVE@#To investigate the alteration of plasma levels of omentin-1 and visfatin in elderly patients with coronary heart disease (CHD) and heart failure.@*METHODS@#Plasma omentin-1 and visfatin levels were measured in 90 subjects (29 stable angina pectoris (SAP) cases, 30 unstable angina pectoris (UAP) cases and 31 age- and sex-matched healthy controls (age ≥ 60 years) by enzyme-linked immunosorbent assay methods. According to the New York Heart Association classification, 59 CHDs were divided into three groups: functional I class, 11 cases; functional II/III class, 36 cases; and functional IV class, 12 cases.@*RESULTS@#The plasma level of omentin-1 in CHD patients was significantly lower than that of the control group. Omentin-1in SAP group and UAP group were significantly lower compared to the control group (there was no statistical significance between UAP group and SAP group; P >0.05). The plasma level of visfatin in CHD patients was significantly higher than that of the control group. Similarly, visfatin in SAP group and UAP group were all significantly higher compared to the control group, while there was no statistical significance between UAP group, and SAP group. The plasma omentin-1 level was negatively correlated with SBP (r=-0.264, P<0.05), positively correlated with HDL-c level (r=0.271, P<0.05); the plasma visfatin level was positively correlated with TC (r=0.292,P<0.05), negatively correlated with HDL-c level (r=-0.266,P<0.05). There was a negative correlation between plasma omentin-1 and visfatin levels (r=-0.280, P<0.05). Moreover, multiple linear stepwise regression analysis showed that omentin-1 and visfatin levels might be affected by HDL-c level. Logistic regression analysis showed that visfatin could be an independent risk factor of CHD.@*CONCLUSIONS@#Decreased levels of omentin-1 and increased levels of visfatin may be involved in the occurrence and development of CHD. Omentin-1 and visfatin, independently, may be protective and pro-inflammatory cytokines. Additionally, both omentin-1 and visfatin may be related to lipid metabolism. Visfatin may be an independent risk factor of CHD.

<p><b>OBJECTIVE</b>To explore the associated factors on loss to follow-up among men who have sex with men (MSM) in a prospective cohort study.</p><p><b>METHODS</b>We recruited eligible HIV-negative MSM at baseline in eight cities from June to October 2009. Interviewer-administrated questionnaire and blood testings for HIV, syphilis and human simplex virus type 2, were accomplished upon enrollment, 6-month and 12-month follow-up visits in the program. Loss to follow-up was recorded at each visit in this cohort. Univariate and multivariate statistical analysis were conducted to examine the associated factors on loss to follow-up.</p><p><b>RESULTS</b>A total of 3196 eligible MSM were enrolled at the baseline study. During one year of follow-up, 894 (28.0%) of them dropped out thoroughly while 2302 (72.1%) showed up at least on one visit. Factors as MSM who were at age 25 or younger, resided locally less than 1 year, being unemployed, self-recognized as heterosexuality or bisexuality, never taking HIV testing in the past year, having had sex with women in the past 6 months etc., were more likely to withdraw from the follow-up visits. Conclusion Age, length of residency, sex orientation and history of HIV testing were associated with the loss of follow-up among MSM cohort in our study. These factors should be considered in this kind of study design in the future.</p>

<p><b>OBJECTIVE</b>To understand the types of, reasons for and sources of stigma and discrimination in a rural community where the majority of people living with HIV/AIDS (PLHA) are former plasma donors (FPDs).</p><p><b>METHODS</b>Eighty local residents, including 20 HIV-positive villagers, 20 family members, 20 villagers from non-HIV-positive households and 20 health workers, were selected as study subjects by using purposive sampling method in rural areas of Anhui Province. Face-to-face interviews and focus group discussions were held to collect information on HIV/AIDS-related stigma and discrimination and its contributing factors.</p><p><b>RESULTS</b>Of the 80 study subjects, 1 didn't finish the survey. Of the 79 subjects who finished the survey, the main forms of stigma and discrimination were expanded stigma [81.0% (64/79)], abandonment and avoidance, stigma and discrimination in healthcare setting [47.4% (28/59)], loss of social support [33.3% (13/39)]. The level of stigma was less in village where were more HIV-positive villagers living and vice versa. The reasons for stigma and discrimination included: ignorance or misunderstanding of HIV/AIDS [57.5% (23/40)], fear of HIV/AIDS [32.5% (13/40)] and morality judgment toward PLHA. The majority of HIV positive participants were unwilling to disclose their positive status to others in order to protect their family members and children.</p><p><b>CONCLUSION</b>Ignorance and misunderstanding of HIV/AIDS were main contributing factors to HIV/AIDS-related stigma and discrimination and it is very important to implement appropriate intervention programs to reduce stigma and discrimination.</p>
