#1
Ming Hao, Stephen H Bryant, Yanli Wang
In this work, we propose a dual-network integrated logistic matrix factorization (DNILMF) algorithm to predict potential drug-target interactions (DTI). The prediction procedure consists of four steps: (1) inferring new drug/target profiles and constructing profile kernel matrix; (2) diffusing drug profile kernel matrix with drug structure kernel matrix; (3) diffusing target profile kernel matrix with target sequence kernel matrix; and (4) building DNILMF model and smoothing new drug/target predictions based on their neighbors...

: Creative arts therapies are proven to promote an interconnection between body and mind, but there are major obstacles for providing therapeutic services in prisons due to inmates' inherent mistrust for verbal disclosure and rigid self-defenses, especially among inmates with schizophrenia. Thus, we developed a structured and quantitative art brut therapy program called go beyond the schizophrenia to actually measure the benefits of art therapy on prison inmates in mainland China. Upon completion of the program, the intervention group reported a decrease in anxiety, depression, anger, and negative psychiatric symptoms and showed better compliance with rules, socialization with peers, compliance with medications, and regular sleeping patterns after 16 weekly sessions of go beyond the schizophrenia...

BACKGROUND: Few studies have investigated metabolic complications in HIV-infected African children and their relation with inflammation. METHODS: We compared baseline and changes in insulin resistance (HOMA-IR) and in markers of inflammation over 48 weeks, in a subset of antiretroviral therapy (ART) naïve Ugandan children from the CHAPAS-3 trial randomized to zidovudine (AZT), stavudine (D4T) or abacavir (ABC) based regimens. Non-parametric methods were used to explore between and within group differences and multivariable analyses to assess associations of HOMA-IR...

Most patients with non-small cell lung (NSCLC), including squamous cell carcinoma, adenocarcinoma and large cell carcinoma, have advanced disease at diagnosis and systemic therapy is the standard-of-care. About 20% of Caucasian patients are affected by an oncogene-addicted advanced NSCLC for which correspondent inhibitors are available. Areas covered: The main state-of-the-art synthetic anticancer drugs in the groups of chemotherapeutics, epidermal growth factor receptor and anaplastic lymphoma kinase tyrosine kinase inhibitors for NSCLC treatment, are reviewed and discussed from phase III randomized practice-changing trials onwards...

BACKGROUND: The effects of antiretroviral therapy on risk of severe bacterial infections in people with high CD4 cell counts have not been well described. In this study, we aimed to quantify the effects of immediate versus deferred ART on the risk of severe bacterial infection in people with high CD4 cell counts in a preplanned analysis of the START trial. METHODS: The START trial was a randomised controlled trial in ART-naive HIV-positive patients with CD4 cell count of more than 500 cells per μL assigned to immediate ART or deferral until their CD4 cell counts were lower than 350 cells per μL...

BACKGROUND: Based on clinical trial results, the WHO recommends infant HIV testing at age 4-6 weeks and immediate antiretroviral therapy (ART) initiation in all HIV-infected infants. Little is known about the outcomes of HIV infected infants diagnosed with HIV in the first weeks of life in resource-limited settings. We assessed ART initiation and mortality in the first year of life among infants diagnosed with HIV by 12 weeks of age. METHODS: Cohort of HIV-infected infants in Kinshasa and Blantyre diagnosed before 12 weeks to estimate 12-month cumulative incidences of ART initiation and mortality, accounting for competing risks...

OBJECTIVE(S): An HIV cure will impose aviraemia which is sustained following the withdrawal of antiretroviral therapy (ART). Understanding the efficacy of novel interventions aimed at curing HIV requires characterisation of both natural viral control and the effect of ART on viral control after treatment interruption. DESIGN: Analysis of transient viral control in recent seroconverters in the SPARTAC trial. METHODS: We compared untreated and treated HIV seroconverters (n = 292) and identified periods of control (plasma VL<400 copies/mL for ≥16 weeks off therapy) in 7...

PURPOSE OF REVIEW: The role of the CD4 cell count in the management of people living with HIV is once again changing, most notably with a shift away from using CD4 assays to decide when to start antiretroviral therapy (ART). This article reflects on the past, current and future role of CD4 cell count testing in HIV programmes, and the implications for clinicians, programme managers and diagnostics manufacturers. RECENT FINDINGS: Following the results of recent randomized trials demonstrating the clinical and public health benefits of starting ART as soon as possible after HIV diagnosis is confirmed, CD4 cell count is no longer recommended as a way to decide when to initiate ART...

BACKGROUND: Drug-drug interactions (DDIs) are one of the major concerns in drug discovery. Accurate prediction of potential DDIs can help to reduce unexpected interactions in the entire lifecycle of drugs, and are important for the drug safety surveillance. RESULTS: Since many DDIs are not detected or observed in clinical trials, this work is aimed to predict unobserved or undetected DDIs. In this paper, we collect a variety of drug data that may influence drug-drug interactions, i...

BACKGROUND: Body composition is an important indicator of nutritional status and health. How body composition changes during 12 mo of breastfeeding in HIV-infected women receiving antiretroviral therapy (ART) is unknown. OBJECTIVE: We assessed whether HIV or food insecurity was associated with adverse postpartum body-composition changes in Ugandan women. DESIGN: A cohort of 246 women [36.5% of whom were HIV positive (HIV+) and were receiving ART] were followed to 12 mo postpartum...

INTRODUCTION: Tumour aftercare (tac) is an essential tool in oncology. The main aim of these follow ups is to diagnose recurrence and second tumours from the beginning. Tac appointments can create a special environment for patients' further concerns. The purpose of the current study was to evaluate tac of patients diagnosed with OSCC and to investigate their health related quality of life (hrql). MATERIAL AND METHODS: A German questionnaire was created by two maxillo-facial surgeons with several years of tac experience...
