1054 Noninvasive Qp/Qs ratio measurement with phase-contrast cine MRI in patients with atrial septal defect: comparison with heart catheterization

The correlation analysis showed a good overlap between measurements (Qp: r = 0.65, p = 0.0004; Qs: r = 0.64, p = 0.0005; Qp/Qs ratio: r = 0.68, p = 0.0002), also confirmed by regression analysis (R2 = 0.42, p < 0.001 for Qp; R2 = 0.41, p = 0.001 for QS; R2 = 0.46, p < 0.001 for Qp/Qs ratio), and by the Bland-Altman statistical analysis for method comparison (see Figure 1). The interobserver variability was low

Systemic, Mucosal Immune Activation and Psycho-Sexual Health in ART-Suppressed Women Living with HIV: Evaluating Biomarkers and Environmental Stimuli

Gender medicine is now an approach that can no longer be neglected and must be considered in scientific research. We investigated the systemic and mucosal immune response in a population of women living with HIV (WLWH) who were receiving successful ART and the sexual and psychological repercussions of HIV infection on the women’s health. As control group, healthy women (HW) matched for age and sex distribution, without any therapy, were included. In summary, our study highlighted the persistence of immune-inflammatory activation in our population, despite virological suppression and a normal CD4 cell count. We found a hyperactivation of the systemic monocyte and an increase in inflammatory cytokine concentrations at the systemic level. The analysis carried out showed a significantly higher risk of HPV coinfection in WLWH compared to HW. Furthermore, our data revealed that WLWH have a profile compatible with sexual dysfunction and generalized anxiety disorders. Our study underlines that patients living with HIV should be evaluated by multidisciplinary teams. These findings also support the idea that more and different immunological markers, in addition to those already used in clinical practice, are needed. Further studies should be carried out to clarify which of these could represent future therapy targets

Conhecimento do cliente diabético em relação os cuidados com os pés Conocimiento de los diabéticos sobre los cuidados con los pies Knowledge about feet care of the diabetic client

Esta pesquisa tem por objetivo avaliar o conhecimento dos clientes que freqüentam um Ambulatório de Diabetes, em relação à sua doença e cuidados com os pés. Na amostra estudada - diabéticos tipo 2 - houve predominância da faixa etária acima de cinqüenta anos e 71,8% tinham diabetes há menos de dez anos. Concluiu-se que os clientes sabem que os cuidados adequados com os pés são necessários para evitar as complicações, porém o autocuidado não é realizado corretamente. Para que isso seja incorporado em seu cotidiano, é fundamental que tenham acesso às informações sobre diabetes, participação da família, além de habilidade e motivação.<br>Este estudio tuvo por objetivo evaluar el conocimiento de los diabeticos tipo 2 atendidos en uno Ambulatorio de Diabetes en relación a su enfermedad y los cuidados con los pies. La major faja de edad fue más de cincuenta años y 71,8% teniam diabetes ha mas de diet años. Los resultados no permitieron concluir que los diabeticos saben que los cuidados adecuados con los pies son necesarios hacia evitar las complicaciónes, pero el atuocuidado no es realizado correctamente. Para incorporar esto en su cotidiano es fundamental que los diabeticos tengam acceso a las informaciones sobre diabetes, allende la participación de la familia, habilidad y motivación.<br>The objective of this research is to evaluate how much the clients that frequently went to the Diabetes Ambulatory, knew about their own ill, and the feet care. In the sample - diabetes type 2 - the majority were people with more than fifty years old and 71.8% were diabetics for more than ten years. So the conclusion that could be taken is that the clients knew about the care that they must have with their feet to don't have complications, but the "own care" is not well done. To insert it in the rightly on their day-by-day they must have acess to the information about diabetes, participation of the family, motivation and their own hability

Awareness, discussion and non-prescribed use of HIV pre-exposure prophylaxis among persons living with HIV/AIDS in Italy: a Nationwide, cross-sectional study among patients on antiretrovirals and their treating HIV physicians

Background: Before Pre-Exposure Prophylaxis (PrEP) was officially recommended and made available, a few surveys among gay and bisexual men, and persons living with HIV/AIDS (PLWHA), identified an informal use of antiretrovirals (ARVs) for PrEP among HIV-negative individuals. Before PrEP availability in Italy, we aimed to assess whether PLWHA in Italy shared their ARVs with HIV-negative individuals, whether they knew people who were on PrEP, and describe the level of awareness and discussion on this preventive measure among them and people in their close circle. Methods: Two anonymous questionnaires investigating personal characteristics and PrEP awareness, knowledge, and experience were proposed to HIV specialists and their patients on ARVs in a one-week, cross-sectional survey (December 2013-January 2014). Among PLWHA, a Multivariable Logistic Regression analysis was conducted to identify factors associated with PrEP discussion with peers (close circle and/or HIV associations), and experience (use in close circle and/or personal ARV sharing). Results: Eighty-seven specialists in 31 representative Infectious Diseases departments administered the questionnaire to 1405 PLWHA. Among specialists, 98% reported awareness, 65% knew the dosage schedule, and 14% had previously suggested or prescribed PrEP. Among PLWHA, 45.6% were somehow aware, discussed or had direct or indirect experience of PrEP: 38% "had heard" of PrEP, 24% were aware of studies in HIV-negative individuals demonstrating a risk reduction through the use of ARVs, 22% had discussed PrEP, 12% with peers; 9% reported PrEP use in close circle and 1% personal ARV sharing. Factors predictive of either PrEP discussion with peers or experience differed between men and women, but across all genders were mainly related to having access to information, with HIV association membership being the strongest predictor. Conclusions: At a time and place where there were neither official information nor proposals or interventions to guide public policies on PrEP in Italy, a significant number of PLWHA were aware of it, and approximately 10% reported PrEP use in their close circle, although they rarely shared their ARVs with uninfected people for this purpose. Official policies and PrEP availability, along with implementation programs, could avoid risks from uncontrolled PrEP procurement and self-administration practices

Comparative evaluation of subtyping tools for surveillance of newly emerging HIV-1 strains

HIV-1 non-B subtypes/circulating recombinant forms (CRFs) are increasing worldwide. Since subtype identification can be clinically relevant, we assessed the added value in HIV-1 subtyping using updated molecular phylogeny (Mphy) and the performance of routinely used automated tools. Updated Mphy (2015 updated reference sequences), used as a gold standard, was performed to subtype 13,116 HIV-1 protease/reverse transcriptase sequences and then compared with previous Mphy (reference sequences until 2014) and with COMET, REGA, SCUEAL, and Stanford subtyping tools. Updated Mphy classified subtype B as the most prevalent (73.4%), followed by CRF02-AG (7.9%), C (4.6%), F1 (3.4%), A1 (2.2%), G (1.6%), CRF12-BF (1.2%), and other subtypes (5.7%). A 2.3% proportion of sequences were reassigned as different subtypes or CRFs because of misclassification by previous Mphy. Overall, the tool most concordant with updated Mphy was Stanford-v8.1 (95.4%), followed by COMET (93.8%), REGA-v3 (92.5%), Stanford-old (91.1%), and SCUEAL (85.9%). All the tools had a high sensitivity (\ue2\u89\ua598.0%) and specificity (\ue2\u89\ua595.7%) for subtype B. Regarding non-B subtypes, Stanford-v8.1 was the best tool for C, D, and F subtypes and for CRFs 01, 02, 06, 11, and 36 (sensitivity, \ue2\u89\ua592.6%; specificity, \ue2\u89\ua599.1%). A1 and G subtypes were better classified by COMET (92.3%) and REGA-v3 (98.6%), respectively. Our findings confirm Mphy as the gold standard for accurate HIV-1 subtyping, although Stanford-v8.1, occasionally combined with COMET or REGA-v3, represents an effective subtyping approach in clinical settings. Periodic updating of HIV-1 reference sequences is fundamental to improving subtype characterization in the context of an effective epidemiological surveillance of non-B strains
