    Abstract Background: Optimising hearing and vision function may be important in improving a range of outcomes for people living with dementia (PwD) and their companions. The SENSE-Cog cross-national randomised controlled trial (RCT) is evaluating the effectiveness of a sensory intervention (SI) to improve quality of life for PwD with concurrent hearing and/or vision impairment, in five European countries. To ascertain how or why the intervention will, or will not, achieve its outcomes, we have designed a process evaluation to explore potential discrepancies between expected and observed outcomes. This will also help us to understand how context may influence the outcomes. Here we describe the protocol for this process evaluation, which is embedded within the RCT.
    Methods/design: We will use a mixed methods approach with a theoretical framework derived from the UK Medical Research Council's' guidance on process evaluations. It will include the following: (1) evaluating how key aspects of the intervention will be delivered, which will be important to scale the intervention in real world populations; (2) characterising the contextual issues, which may shape the delivery and the impact of the intervention in different countries; and (3) investigating possible causal mechanisms through analyses of potential moderators and mediators. To avoid bias, we will analyse the process data before the analysis of the main effectiveness outcomes.
    Discussion: This evaluation will provide insight into how the complex SENSE-Cog SI will be tailored, enacted and received across the different European contexts, all of which have unique health and social care economies. The findings will provide insight into the causal mechanisms effecting change, and will determine whether we should implement the intervention, if effective, on a wider scale for PwD and concurrent sensory impairment.

    Abstract Objective: Boys with posterior urethral valves (PUV) present an increased risk of febrile urinary tract infection (fUTI). Identifying specific risk factors could allow for tailoring UTI prevention. The aim of this study was to use the data from the CIRCUP randomized controlled trial data to identify patient characteristics associated with a higher risk of fUTI.
    Patients and methods: We performed a secondary analysis of the data from the CIRCUP randomized trial which included boys with PUV, randomized to circumcision and antibiotic prophylaxis vs. antibiotic prophylaxis alone and followed for 2 years. There was only 1 episode of fUTI in the circumcision group vs. 17 in the uncircumcised group. We therefore only studied the antibiotic prophylaxis alone group and compared age at prenatal diagnosis, size and weight at birth, presence of dilating VUR at diagnosis, abnormal DMSA scan at 2 months, and nadir creatinine between children who presented a fUTI and those who did not, as well as age at first episode of fUTI.
    Results: The study group consisted of 42 patients of which 17 presented at least on fUTI. Presence of dilating VUR was significantly associated with risk of fUTI (
    Conclusion: In boys with PUV, presence of high-grade VUR is associated with a higher risk of presenting a fUTI. The rate of febrile UTIs seems to decrease after 9 months.

    Abstract The HIV-2 long terminal repeat (LTR) region contains several transcription factor (TF) binding sites. Efficient LTR transactivation by cellular TF and viral proteins is crucial for HIV-2 reactivation and viral production. Proviral LTRs from 66 antiretroviral-naive HIV-2-infected patients included in the French ANRS HIV-2 CO5 Cohort were sequenced. High genetic variability within the HIV-2 LTR was observed, notably in the U3 subregion, the subregion encompassing most known TF binding sites. Genetic variability was significantly higher in HIV-2 group B than in group A viruses. Notably, all group B viruses lacked the peri-ETS binding site, and 4 group B sequences (11%) also presented a complete deletion of the first Sp1 binding site. The lack of a peri-ETS binding site was responsible for lower transcriptional activity in activated T lymphocytes, while deletion of the first Sp1 binding site lowered basal or Tat-mediated transcriptional activities, depending on the cell line. Interestingly, the HIV-2 cellular reservoir was less frequently quantifiable in patients infected by group B viruses and, when quantifiable, the reservoirs were significantly smaller than in patients infected by group A viruses. Our findings suggest that mutations observed

    Abstract Human immunodeficiency viruses induce rare attenuated diseases due either to HIV-1 in the exceptional long-term nonprogressors (LTNPs) or to HIV-2 in West Africa. To better understand characteristics of these two disease types we performed a multiplex comparative analysis of cell activation, exhaustion, and expression of coreceptors and restriction factors in CD4 T cells susceptible to harbor those viruses. We analyzed by flow cytometry the expression of HLA-DR, PD1, CCR5, CXCR6, SAMHD1, Blimp-1, and TRIM5α on CD4 T cell subsets from 10 HIV-1

    Abstract Background: Hearing and vision impairments are highly prevalent in people with dementia and may have a negative impact on quality of life and other dementia-related outcomes. Intervening to optimise sensory impairment and support sensory function may be a means of improving dementia-related outcomes. The SENSE-Cog trial will test whether a home-based multi-part sensory intervention is effective in improving quality of life and other key outcomes in people with dementia and hearing or vision problems (or both) and their companions.
    Methods: This is an European, multi-centre, observer-blind, pragmatic, randomised controlled trial. Three hundred fifty four people with dementia and hearing or vision impairment (or both) and their companions will be randomly assigned to receive either "care as usual" or a multi-component sensory intervention including assessment and correction of hearing or vision impairments (or both), home-based (maximum 10 visits over 18 weeks), therapist-delivered sensory support (that is, adherence to devices; improving the sensory environment (that is, lighting), communication training, and sign-posting to other support agencies). Change from baseline to intervention end (18 weeks) and post-intervention (36 weeks) will be compared between the two arms in the following outcomes: quality of life (primary endpoint), sensory and cognitive functional ability, relationships, mental well-being, health resource utilisation and cost-effectiveness.
    Discussion: This is one of two articles outlining the SENSE-Cog trial. Here, we describe the protocol for the effectiveness of the SENSE-Cog intervention. A parallel and complementary process evaluation will be described elsewhere. If the SENSE-Cog trial demonstrates that the sensory intervention improves outcomes in dementia, we will make a toolkit of training materials, resources and information available to health and social care providers to implement the intervention in routine practice. This will be a significant contribution to the therapeutic management of people with dementia and sensory impairment.

    Abstract Background: The management of patients with locally recurrent rectal cancer (LRRC) is often complex and requires multidisciplinary input whereas only few patients are referred to a specialist centre. The aim of this study was to design a regional referral pathway for LRRC, in Nouvelle Aquitaine (South-West, France).
    Methods: In 2016, we conducted with a Study Steering Committee (SC) a three phase mixed-methods study including identification of key factors, identification of key stakeholders and Delphi voting consensus. During three rounds of Delphi voting, a consensus was defined as favorable, if at least 80% of participating experts rate the factor, below or equal to 3/10 using a Likert scale, or consider it as "useful" using a binary scale (third round only). Finally, the SC drafted guidelines.
    Results: Among the 423 physicians involved in 29 regional digestive Multi-Disciplinary Team (MDT) meeting, 59 participants (from 26 MDT meeting) completed all three rounds of Delphi voting. Thirteen out of twenty initially selected factors reached a favorable consensus. All patients with a LRRC need to be included into a referral pathway. Patients with a central pelvic recurrence offered curative treatment in their local hospital and patients with unresectable metastatic disease were excluded of the referral. Key performance indicators were also agreed including the time to referral and completion of pelvic MRI-, CT-, PET-scan prior to MDT referral.
    Conclusion: The development of this referral pathway represents an innovative health service, which will improve the management of patients with LRRC in France.

    Abstract Background: New options for first-line treatment of human immunodeficiency virus type 2 (HIV-2) infection are needed. We evaluated an integrase inhibitor (raltegravir)-containing regimen.
    Methods: Antiretroviral therapy (ART)-naive adults with symptomatic infection by HIV-2 only, CD4 count <500 cells/μL or CD4 decrease >50 cells/μL/year over the past 3 years, or a confirmed plasma HIV-2 RNA (pVL) load ≥100 copies/mL were eligible for this noncomparative trial. The composite primary endpoint was survival at 48 weeks without any of the following: CD4 gain from baseline <100 cells/μL, confirmed pVL ≥40 copies/mL from week 24, raltegravir permanent discontinuation, or incident B or C event. HIV-2 ultrasensitive pVL (uspVL) and total DNA were assessed using in-house polymerase chain reaction (PCR) assays.
    Results: Baseline median CD4 count of 30 enrolled individuals (67% women) was 436 cells/µL (interquartile range [IQR], 314-507 cells/µL); pVL was ≥40 copies/mL in 67% of them, uspVL was ≥5 copies/mL in 92%, and total DNA was >6 copies by PCR in 32%. At week 48, the composite endpoint of success was reached in 40% [95% confidence interval, 22.7%-59.4%]. Failure was mainly (50%) due to CD4 gain <100 cells/µL; uspVL was <5 copies/mL in 87% and total DNA >6 copies by PCR in 12% of participants. Median CD4 gain was 87 cells/µL (IQR, 38-213 cells/µL; n = 28). No serious adverse reactions were reported.
    Conclusions: Raltegravir-containing ART is a safe option for first-line treatment of HIV-2 infection, yielding a comparable success rate to protease inhibitors.

    Abstract The low pathogenicity and replicative potential of HIV-2 are still poorly understood. We investigated whether HIV-2 reservoirs might follow the peculiar distribution reported in models of attenuated HIV-1/SIV infections, i.e. limited infection of central-memory CD4 T lymphocytes (TCM). Antiretroviral-naive HIV-2 infected individuals from the ANRS-CO5 (12 non-progressors, 2 progressors) were prospectively included. Peripheral blood mononuclear cells (PBMCs) were sorted into monocytes and resting CD4 T-cell subsets (naive [TN], central- [TCM], transitional- [TTM] and effector-memory [TEM]). Reactivation of HIV-2 was tested in 30-day cultures of CD8-depleted PBMCs. HIV-2 DNA was quantified by real-time PCR. Cell surface markers, co-receptors and restriction factors were analyzed by flow-cytometry and multiplex transcriptomic study. HIV-2 DNA was undetectable in monocytes from all individuals and was quantifiable in TTM from 4 individuals (median: 2.25 log10 copies/106 cells [IQR: 1.99-2.94]) but in TCM from only 1 individual (1.75 log10 copies/106 cells). HIV-2 DNA levels in PBMCs (median: 1.94 log10 copies/106 PBMC [IQR = 1.53-2.13]) positively correlated with those in TTM (r = 0.66, p = 0.01) but not TCM. HIV-2 reactivation was observed in the cells from only 3 individuals. The CCR5 co-receptor was distributed similarly in cell populations from individuals and donors. TCM had a lower expression of CXCR6 transcripts (p = 0.002) than TTM confirmed by FACS analysis, and a higher expression of TRIM5 transcripts (p = 0.004). Thus the low HIV-2 reservoirs differ from HIV-1 reservoirs by the lack of monocytic infection and a limited infection of TCM associated to a lower expression of a potential alternative HIV-2 co-receptor, CXCR6 and a higher expression of a restriction factor, TRIM5. These findings shed new light on the low pathogenicity of HIV-2 infection suggesting mechanisms close to those reported in other models of attenuated HIV/SIV infection models.
