ABSTRACT
Multiple sclerosis (MS) is a demyelinating autoimmune disease of the central nervous system. It mainly occurs in young and middle-aged people and has a high disability rate. The pathogenesis of MS has not been fully elucidated, with great genetic heterogeneity, diverse clinical phenotypes, lack of specific biomarkers, numerous and complicated research data, which bring great challenges to the diagnosis and treatment of MS. Artificial intelligence (AI), as the cutting-edge hotspot in the development of science and technology, is widely used in the medical field to assist in the diagnosis, treatment and prognosis of various diseases. Its infinite learning ability greatly promotes the management of MS. This article will review the application of AI in MS diagnosis and treatment.
ABSTRACT
Objective To examine the prevalence of depressive symptoms and related factors among HIV-positive men who have sex with men (MSM) in Shanghai.Methods All of the HIV-positive MSM were enrolled to participate in a cross-sectional study with questionnaire-based interview during Nov.,2014 to Nov.,2015.Depression was measured with a 12-item version of the Center for Epidemiological Studies Depression Scale (CES-D),where a score of 9 had been recommended as the cutoff score to indicate possible depressive symptoms.Results A total of 505 participants were recruited with a median age of 30.Among them,the majority were aged 21-44 (77.2％),non-local resident (64.6％),unmarried (73.1 ％) and university graduate or above (62.1 ％).Depressive symptoms were detected from 235 MSM and the prevalence of depression was 46.5 ％.Multiple logistic regression analysis showed that MSM who were non-local residents (OR =1.66,95 ％ CI:1.01-2.49)and had more than one male sex partner in the past year (OR=2.21,95％ CI:1.43-3.41) were more likely to have depressive symptoms compared with local residents and had only one male sex partner or less.On the contrary,compared with the education level of junior middle school or below and having no long-term partners,those who were senior high school educated (OR=0.39,95％ CI:0.21-0.74) and had homosexual behavior with main long-term partners without condoms (OR =0.38,95 ％ CI:0.17-0.85) had lower risk to be depressive.Conelusions The prevalence of depressive symptoms among HIV-infected MSM is high.Residence,education level,homosexual behavior with main long-term partner and number of male sex partner are significantly associated with depressive symptoms,suggesting psychological interventions should be further explored and studied.
