If any one of the following four conditions is present in some persons, i.e., (1) EBV VCA/IgA titer>1:80, (2) EBV EDAb>60%, (3) Dual or triple positiveness in VCA/IgA, EA/IgA and EDAb, (4) Any one of VCA/IgA, EA/IgA and EDAb keeps high titer or going up, they should be regarded as in precancerosis of NPC. The moderate or severe heteroplasia and heterometaplasia of nasopharyngeal mucosa are the precancerous lesions of NPC. Some individual who is in precancerosis or with precancerous lesion should be regarded as the high risk population of NPC. The results are of important scientific basis for screening and second degree prevention of NPC.展开更多

Poor blood transfusion methods along with unsafe injection practices are potential sources for the rapid spread of infection. Early detection of HCV is the need of the hour especially in high riskgroup population as these individuals are severely immunocompromised. Enzyme Immunoassays are the most common detection techniques but they provide no evidence of active viremia or identification of infected individuals in the antibody-negative phase and their efficacy is limited in individuals within high risk group population. Molecular virological techniques have an important role in detecting active infection with utmost specificity and sensitivity. Technologies for assessment of HCV antibody and RNA levels have improved remarkably, as well as our understanding of how to best use these tests in patient management. This review aims to give an overview of the different serological and molecular methods employed in detecting HCV infection used nowadays. Additionally, the review gives an insight in the new molecular techniques that are being developed to improve the detection techniques particularly in High Risk Group population who are severely immunocompromised.展开更多

Methods: Using cluster sampling, on-site investigations were conducted on 1060 permanent residents aged 40 years and over at 3 townships and 2 communities in Shashi District of Jingzhou City from January 2018 to December 2018. Risk assessment of stroke is based on the stroke risk screening form. Statistical analysis was performed by using SPSS 22.0 software. Results: After making a stroke risk assessment, a total of 313 high-risk stroke patients were screened, and the detection rate was 29.53%. The exposure rate of risk factors from high to low was hypertension (70.93%), dyslipidemia (46.33%), less physical exercise (46.01%), diabetes (36.10%), overweight (33.55%), smoking (33.23%), family history of stroke (24.92%), atrial fibrillation or valvular heart disease (7.35%). There are statistically significant differences among all risk factors between the high-risk group and middle and low-risk groups (P Conclusion: The detection rate of high-risk stroke patients in Shashi District of Jingzhou City is high. Hypertension, dyslipidemia and less physical exercise are the main risk factors of stroke occurrence and recurrence in the region. The prevention and treatment of risk factors for stroke should be strengthened to control the incidence and recurrence rate of stroke.展开更多

Methods Region-specific population, behavior, serosurveillence, and policy/program data （from 1995 to 2020） were gathered from various local and national organizations and applied to the Asian Epidemic Model （AEM） and used to derive estimates of future HIV prevalence, epidemic trends, and outcomes of intervention strategies. Results The AEM projections for 2020 included increased number of people living with HIV （PLHIV; to 136 617）, increased HIV prevalence （2.51%）, and 8037 deaths from acquired immunodeficiency syndrome （AIDS） in this region. However, the overall HIV incidence rate （per 10 000） was projected to decline from 27 in 2015 to 22 in 2020, largely due to a predicted decrease in HIV infection rate （per 10 000） from 658 in 2013 to 621 in 2020 among intravenous drug users. In contrast, the cases of HIV infection per i0 000 was projected to increase from 420 in 2010 to 503 in 2020 among men who have sex with men, and from 8 in 2010 to 15 in 2020 among the general population. The predominant risk factor for HIV transmission over the next decade in Liangshan was casual sex. Community-based outreach strategies to reduce injected drug use and casual sex, and to promote condom use, were predicted as effective interventions to decrease HIV transmission. Conclusion Implementation of a comprehensive public health program, with targeting to the region-specific at-risk populations, will help to mitigate HIV/AIDS spread in Liangshan.展开更多

Methods: A ret rospective survey of 1 725 cases with HCC after radical and relatively radical operation was performed. The follow-up rate was 84. 5%. The significant factors were analysed using Cox proportional hazards survival analysis model,and the disease-free survival was analysed using Kapalan-Meier estimination. Results: Uni variate analysis shows twelve prognostic clinicopathological factors. Multivariate analysis revealed 4 signifi cant prognostic factors: preoperative tumor number,tumor size,daughter nodules and vascular invasion. Ka palan-Meier estimination showed disease-free survival in subclinical stage was much better than in stage 2 or 3. Conclusion:Screening in the high risk population of HCC and having check-up of AFP and B ultrasono graphy of liver regularly themselvs can detect tumor of patients in early stage,so that they can have surgical treatment in subclinical stage,and have their disease-free survival time increased much more.展开更多

This study examines the prevalence and correlates of depression among MSM. Data and Methods: Data for this study are used from a cross-sectional Behavioral Tracking Survey—2012 conducted among 1176 MSM from Andhra Pradesh (undivided), a southern state of India. Depression of MSM was assessed using Patient Health Questionnaire-2 scale. Descriptive statistics, bivariate and multivariate logistic regression techniques were used for analysis. Results: More than one-third of MSMs (35%) in the survey reported to have depression. The likelihood of experiencing depression was 5 times higher among MSM who were mobile for sex work outside their place of residence (55% vs 17%, AOR: 5.2, 95% CI: 3.7 - 7.3) and had experienced physical or sexual violence (82% vs 33%, AOR: 6.0, 95% CI: 2.1 - 17.4) than their respective counterparts. Rates of depression were significantly higher among MSM who had experienced Sexually Transmitted Infections symptoms;knowledge of their HIV positivity;who didn’t use condoms during anal sex with any clients/partners;those who consumed alcohol and were in financial debt at the time of survey than others. Those who were associated with any community groups have significantly less chances of reporting depression. Discussion: The study certainly highlighted that the HIV prevention efforts with MSM in India require an integrated approach on addressing the mental health issues. To support this, programs and research-based evidence will be highly needed to ensure that mental health issues are properly addressed among MSM and other high risk groups.展开更多
