Abstract
Identifying biomarkers of Multiple Sclerosis is important for the diagnosis and treatment of Multiple Sclerosis. The existing study has shown that miRNA is one of the most important biomarkers for diseases. However, few existing methods are designed for predicting Multiple Sclerosis-related miRNAs. To fill this gap, we proposed a novel computation framework for predicting Multiple Sclerosis-associated miRNAs. The proposed framework uses a network representation model to learn the feature representation of miRNA and uses a deep learning-based model to predict the miRNAs associated with Multiple Sclerosis. The evaluation result shows that the proposed model can predict the miRNAs associated with Multiple Sclerosis precisely. In addition, the proposed model can outperform several existing methods in a large margin.

Abstract
Introduction Cognitive impairment is also an important cause of disability in MS in addition to motor, sensory, visual, and cerebellar affections. The aim of this study is to show the relation between the cognitive disability in MS with brain atrophy and retinal nerve fiber layer (RNFL). Methods Forty-three multiple sclerosis (MS) patients, and 15 healthy individuals as controls were included in the study. MS patients were divided into three groups as relapsing-remitting MS (RRMS), relapsing-remitting with optic neuritis (RRMS+ON), and secondary-progressive MS (SPMS). An experienced psychologist performed modified Wechsler Memory Scale Revised form (WMS-R), Lines Orientation test, Stroop Color Word Interference test (STROOP), Standard Raven Progressive Matrices (SRPM), Benton Facial Recognition Test, verbal fluency test, and Paced Auditory Serial Addition tests in all cases. Optic coherence tomographies (OCT) were done. Cranial subcortical volumes of all subjects were measured using 3-dimensonal T1A imagines obtained by the cranial subcortical 1.5 tesla MR device (fully automatic Freesurfer program). Brain parenchymal fractions were calculated by proportioning the obtained volume measurements to the total intracranial volume. Results Fifty-eight subjects (65.5% female, 34.5% male) were enrolled in the study. There were significant differences among the groups in terms of parenchymal thickness, volumes of third ventricle, and white matter. There was a significant correlation between the volumes of the deep gray matter, mesial temporal structures and lateral ventricular volumes, and the test results of the WMS-R. OCT scores of all MS patients, whether or not they experienced optic neuritis, had increased, being worse especially in the SPMS group. Correlation between RNFL and the brain parenchymal fractions of the patients were statistically significant. Conclusion Manual methods instead of automatic segmentation method are being more commonly used in the studies with brain atrophy and MS in our country. A significant correlation between OCT scores and brain atrophy is shown with our present study, and this is followed as a reflection of decrease in cognitive tests that provides valuable and reliable knowledge for the literature.

Abstract
This review focuses on the "real world" implications of infection with HIV/AIDS from a neuropsychological perspective. Relevant literature is reviewed which examines the relationships between HIV-associated neuropsychological impairment and employment, driving, medication adherence, mood, fatigue, and interpersonal functioning. Specifically, the relative contributions of medical, cognitive, psychosocial, and psychiatric issues on whether someone with HIV/AIDS will be able to return to work, adhere to a complicated medication regimen, or safely drive a vehicle will be discussed. Methodological issues that arise in the context of measuring medication adherence or driving capacity are also explored. Finally, the impact of HIV/AIDS on mood state, fatigue, and interpersonal relationships are addressed, with particular emphasis on how these variables interact with cognition and independent functioning. The purpose of this review is to integrate neuropsychological findings with their real world correlates of functional behavior in the HIV/AIDS population.

Abstract
BACKGROUND Antiretroviral regimens for HIV-infected patients require strict adherence. Untreated depression has been associated with medication nonadherence. We proposed to evaluate the effect of antidepressant treatment (ADT) on antiretroviral adherence. METHODS Data were retrieved for HIV-infected patients seen at an urban health care setting (1997-2001) from chart review and administrative and pharmacy files. Antiretroviral adherence was determined for depressed patients stratified by receipt of and adherence to ADT. Antiretroviral adherence was compared before and after initiation of ADT. RESULTS Of 1713 HIV-infected patients, 57% were depressed; of those, 46% and 52% received ADT and antiretroviral treatment, respectively. Antiretroviral adherence was lower among depressed patients not on ADT (vs. those on ADT; P = 0.012). Adherence to antiretroviral treatment was higher among patients adherent to ADT (vs. those nonadherent to antidepressant treatment; P = 0.0014). Antiretroviral adherence improved over a 6-month period for adherent, nonadherent, and nonprescribed ADT groups; however, the mean pre- versus post-6-month change in antiretroviral adherence was significantly greater for those prescribed antidepressants. CONCLUSIONS Depression was common, and antiretroviral adherence was higher for depressed patients prescribed and adherent to ADT compared with those neither prescribed nor adherent to ADT. Attention to diagnosis and treatment of depressive disorders in this population may improve antiretroviral adherence and ultimate survival.

Abstract
OBJECTIVE Our aim was to gain an estimate of the rate of depressive disorder in patients with HIV/AIDS attending general practice and to investigate factors associated with depression. A further objective was to determine the ability of non-mental health medical practitioners to detect depressive symptoms in their patients with HIV/AIDS. METHODS Participants comprised 322 persons living with HIV/AIDS ( (PLWHA); 13 females, 309 males; mean age 41.4, SD = 8.9) who were recruited from four general practice clinics specializing in HIV medicine and from an infectious diseases clinic. Medical, psychiatric and sociodemographic data were obtained. In addition, participants completed the Inventory to Diagnose Depression (IDD), a self-report measure to detect depression. RESULTS Twenty-two per cent of the sample met criteria for a current Major Depressive Episode (DSM-IV defined) on the IDD. Overall, there was moderate agreement between treating doctors' diagnosis of depression and patients' self-report of depressive symptoms. A multivariate model indicated that being in a current relationship was associated with lowered odds of depression (OR = 0.43; CI = 0.23-0.81). The factors strongly associated with increased odds of depression were a past history of illicit drug use (OR = 2.98; CI = 1.60-5.54) and a diagnosis of 'stress' by treating doctors (OR = 5.65; CI = 2.50-12.77). HIV-related medical variables such as immune function, use of antiretro-viral medication and duration of HIV infection were not associated with depression. CONCLUSIONS There was a high rate of self-reported depression in this group of PLWHA which was also recognized by treating clinicians. Being in a relationship appeared to afford protection against depression while having a history of illicit drug use and current 'stress' were highly associated with depression. Interestingly, HIV-related medical variables including laboratory markers of HIV disease, duration of illness and antiretroviral medication regimen were not related to depression.

Abstract
Normal aging is accompanied by a wide range of changes in brain structure and function. In this work we seek to examine the hypothesis that normal aging results in neuropsychological findings similar to those produced by neuropsychological impairment related to AIDS. Specifically, we attempt to compare the level of neuropsychological performance in three groups: a normal elderly group (n = 46), a young group of AIDS patients (n = 36), and a young group of normal subjects (n = 22). The results indicated that, despite age differences between the normal elderly and AIDS patients, there was great similarity in the neuropsychological test performance of these two groups. In contrast, both groups demonstrated significantly different neuropsychological test performance than that evidenced by the younger normal controls. These results support the notion that neuropsychological changes related to normal aging are of a nature similar to those observed in AIDS and, therefore, affect functions subserved by frontal-subcortical brain regions.

Abstract
OBJECTIVE This study aimed to investigate rates of psychiatric disorder in human immunodeficiency virus (HIV) infection, in an Australian sample of homosexual and bisexual men. METHOD A cross-sectional study of a total of 65 HIV sero-negative (HIV-) and 164 HIV sero-positive men (HIV+) (79 CDC stage II/III and 85 CDC stage IV) was conducted in three centres. Lifetime and current prevalence rates of psychiatric disorder were evaluated using the Diagnostic Interview Schedule Version IIIR (DIS-IIIR). RESULTS Elevated current and lifetime rates of major depression were detected in both HIV negative and HIV positive homosexual/bisexual men. Lifetime rates of alcohol abuse/dependence were significantly elevated in HIV positive men (CDC group IV) when compared with HIV negative men. Among the HIV positive group the majority of psychiatric disorders detected were preceded by a pre-HIV diagnosis of psychiatric disorder. Major depression represented the disorder most likely to have first onset after HIV infection diagnosis. CONCLUSIONS Lifetime rates of major depression were elevated in this sample of HIV-negative and HIV-positive men. In the HIV-positive men, psychiatric disorder was significantly associated with the presence of lifetime psychiatric disorder prior to HIV infection diagnosis. The findings indicate the importance of evaluation of psychiatric history prior to HIV infection and the clinical significance of depressive syndromes in this population.

Abstract
Since S. Rao's ["Neuropsychology of Multiple Sclerosis: A Critical Review," A Journal of Clinical and Experimental Neuropsychology, Vol. 85, pp. 503-542] (1986) seminal review, considerable research has been undertaken on the neuropsychological consequences of multiple sclerosis. This review incorporates the research literature of the last decade in presenting an overview of the current state of our knowledge concerning the etiology, course, symptoms, assessment, consequences, and treatment of multiple sclerosis (MS). The concept of subcortical dementia is revisited in light of the most recent literature documenting the neuropsychological deficits in patients with MS. The view that cognitively heterogeneous patient groups may disguise more specific patterns of focal neuropsychological impairment is considered. A critical review of the recent literature is also presented, detailing the degree to which recent research has addressed the areas of research need identified by Rao in 1986. Given recent advances in our knowledge, the need for more attention to be directed toward the evaluation of rehabilitation and psychological intervention is highlighted.

Abstract
Neuropsychological studies of multiple sclerosis (MS) from a 20-year period were reviewed using meta-analytic and vote-count techniques. Mean effect sizes comparing MS and healthy control groups on variables categorized by neuropsychological domain were small to moderate in magnitude; all were statistically significant (M(r) = .22 (.13) to .46 (.15), rW = .23 to .43, all p < .05). Interhemispheric transfer, general cognitive ability, and learning/memory were more highly related to MS than were visuoperceptual, visuospatial, and visuoconstructional ability, language and conceptual ability (all p < .05); other domains were generally intermediate. Despite previous reports to the contrary, disease subtype was not shown to be consistently related to neuropsychological status independently of other potential explanatory variables. Findings were interpreted with regard to future research and clinical activities involving patients with MS, including selection of tests for brief neuropsychological screening examinations.

Abstract
In this paper we review studies of depression in patients with HIV/AIDS. Methodological issues of importance in understanding and evaluating depression in this patient population are described, and methodological variations between studies, particularly in reference to methods of case detection, diagnostic criteria used and characteristics of the populations studied, are identified. The findings reported in the current literature in general are contrary to what would be expected from an examination of the significant biological and psychosocial stresses of individuals with HIV, and are inconsistent with those of other life-threatening illnesses and CNS diseases. Clear conclusions regarding the prevalence of depression and its effect in patients with HIV/AIDS cannot yet be made.

Abstract
The aim of this study was to establish the prevalence of current and past psychiatric morbidity in HIV seropositive asymptomatic subjects belonging to three transmission categories (gay men, intravenous drug users, and heterosexuals) compared with that found in HIV seronegative controls from the same groups. A cross-sectional, controlled study including 279 seropositive subjects belonging to groups II and III defined by the Center for Disease Control (94 gay men, 157 intravenous drug users, and 28 heterosexuals) and 159 seronegative subjects (38 gay men, 91 intravenous drug users, and 30 heterosexuals) is reported. Outcome measures included standardised, self-report questionnaires and a semistructured interview to assess current psychopathological status and past psychiatric history. In addition, a psychiatric diagnosis according to DSM-III-R criteria Axis I and II was made in the seropositive subjects. Results showed that these subjects differed very little from the controls and that overall levels of psychiatric disturbances in both groups were low and similar to those found in other life-threatening illnesses. Furthermore, intravenous drug users, regardless of HIV serological status, had the highest levels of psychological morbidity. Psychosocial distress was associated with previous and current lifestyle, independently of HIV status.
