Abstract
Improved understanding of multimorbidity (MM) treatment adherence in primary health care (PHC) in Brazil is needed to achieve better healthcare and service outcomes. This study explored experiences of healthcare providers (HCP) and primary care patients (PCP) with mental-physical MM treatment adherence. Adults PCP with mental-physical MM and their primary care and community mental health care providers were recruited through maximum variation sampling from nine cities in São Paulo State, Southeast of Brazil. Experiences across quality domains of the Primary Care Assessment Tool-Brazil were explored through semi-structured in-depth interviews with 19 PCP and 62 HCP, conducted between April 2016 and April 2017. Through thematic conent analysis ten meta-themes concerning treatment adherence were developed: 1) variability and accessibility of treatment options available through PHC; 2) importance of coming to terms with a disease for treatment initation; 3) importance of person-centred communication for treatment initiation and maintenance; 4) information sources about received medication; 5) monitoring medication adherence; 6) taking medication unsafely; 7) perceived reasons for medication non-adherence; 8) most challenging health behavior change goals; 9) main motives for initiation or maintenance of treatment; 10) methods deployed to improve treatment adherence. Our analysis has advanced the understanding of complexity inherent to treatment adherence in mental-physical MM and revealed opportunities for improvement and specific solutions to effect adherence in Brazil. Our findings can inform research efforts to transform MM care through optimization.

Performance of Treponema pallidum recombinant proteins in the serological diagnosis of syphilis. PLoS One 2020; 15:e0234043.

Abstract
Syphilis serodiagnosis is challenging because distinct clinical forms of the infection may influence serological performance and discordant results between tests make clinical decisions difficult. Several recombinant Treponema pallidum-proteins have already been tested for syphilis diagnosis and they are critical to achieve high accuracy in serological testing. Our aim was to assess the varied from performance of T. pallidum-recombinant proteins TmpA, TpN17 and TpN47 for syphilis serodiagnosis. The proteins were evaluated using sera of 338 T. pallidum-negative, 173 T. pallidum-positive individuals and 209 sera from individuals infected with unrelated diseases. The diagnostic potential was validated by analysis of ROC curves. In the liquid microarray analyses, the ROC curve varied from 99.0% for TmpA and TpN17 to 100% for TpN47. The sensitivity score yielded values of up to 90% for TpN17, 100% for TpN47 and 80.0% for TmpA. The lowest and highest specificity values were presented by TpN47 (91.9%) and TmpA antigens (100%), respectively. TpN47 showed the highest accuracy score (95.5%) among all the recombinant proteins assayed. For the ELISA, the ROC curve was 97.2%, 91.8% and 81.6% for TpN17, TmpA and TpN47, respectively. TpN17 and TmpA yielded a sensitivity of 69.9%, while TpN47 obtained a value of 53.8%. Specificity was almost 100% for all three proteins. No cross-reaction was observed for TpN17 in the serum samples from non-bacterial infections. Regarding leptospirosis-positive samples, cross-reactivity score was varied from 8.6 to 34.6%. This is most probably due to conservation of the epitopes in these proteins across bacteria. The use of recombinant proteins in immunoassays for syphilis diagnosis was showed provide greater reliability to results of the treponemal assays. Despite the low sensitivity, the proteins showed high diagnostic capacity due to the AUC values found. However, an improvement in sensitivity could be achieved when antigenic mixtures are evaluated.
