Contabilidade e relato dos intangíveis: Análise das empresas cotadas na BM&FBOVESPA

O presente trabalho de investigação avalia a situação atual relativa à adoção do disposto na IAS 38 e suas consequências no reconhecimento, mensuração e divulgação obrigatória, e à divulgação voluntária, interna e externa, dos intangíveis nas empresas brasileiras cotadas na BM&FBOVESPA. Adotando a perspectiva positivista e uma abordagem quantitativa, foi utilizado o inquérito por questionário como método de recolha de dados. O questionário foi elaborado de raiz, suportado pelo arcabouço teórico. Os resultados são interpretados à luz dos argumentos da teoria dos stakeholders e da teoria institucional, que revelaram um bom potencial explicativo para o fenômeno em análise. Com a adoção das IAS/IFRS para elaboração dos balanços consolidados de empresas cotadas e não cotadas, o Brasil passa a utilizar a IAS 38, para o registro das operações envolvendo os ativos intangíveis, obrigatoriamente no exercício de 2010. A adoção deste normativo se deu essencialmente por pressões legais. No entanto, as empresas que adotaram a IAS 38 de forma voluntária validaram as razões apresentadas na literatura. Constatou-se que existe concordância quanto à nova forma de contabilização dos intangíveis prevista, sendo o grau de satisfação relativamente ao tratamento contábil dos ativos intangíveis de acordo com o novo modelo contábil adotado no Brasil (IAS 38 e CPC 04) elevado. Como principais dificuldades no reconhecimento contábil dos ativos intangíveis segundo o normativo em vigor, foram confirmados os problemas evidenciados na literatura, tais como incerteza quanto aos benefícios econômicos futuros e falta de medida com confiabilidade suficiente para o registro das transações. As empresas brasileiras acreditam ser importante que haja uma expansão da divulgação sobre intangíveis, no entanto a divulgação interna e externa está ainda em fase embrionária, não sendo uma prática generalizada. Contudo, os objetivos apresentados na literatura para a divulgação interna e externa de informações sobre intangíveis encontram suporte empírico no estudo desenvolvido. No que diz respeito aos stakeholders, conclui-se que as empresas brasileiras têm grande preocupação em atendê-los quando se trata de divulgação voluntária sobre intangíveis, entendendo que todos eles poderão beneficiar com estas informações.

Control de la función reproductiva postparto en vacas de cría

Los prolongados períodos de anestro constituyen la principal causa de infertilidad durante el puerperio en los rodeos de cría. Algunas estimaciones revelan que sólo el 50% de los vientres en edad reproductiva destetan un ternero por año, lo que se traduce en importantes pérdidas económicas para el sector de producción de carne. La duración del período anovulatorio postparto está determinada fundamentalmente por las influencias inhibitorias del amamantamiento y de la subnutrición sobre el eje hipotálamo-hipofisiario.(...) Según estimaciones del Censo Nacional Agropecuario (INDEC, 1998) existen en la Argentina aproximadamente 25 millones de vientres bovinos en edad reproductiva y las tasas promedio de destete anual no superan el 52%. Los prolongados períodos de anestro constituyen la causa primordial de esta baja tasa de procreo. El desarrollo de alternativas más eficientes para lograr la interrupción o acortamiento del anestro postparto posibilitará mejorar sustancialmente los índices mencionados. (...) Resultados recientes en nuestro laboratorio demostraron que en vacas en anestro postparto el tratamiento combinado de progesterona más estradiol 17b (E-17b) induce la emergencia sincronizada de una nueva onda folicular y altas tasas de ovulación sincronizada luego de un destete de 48h y GnRH. Objetivos generales y específicos Desarrollar y evaluar alternativas más eficientes para el control de la función reproductiva postparto en el ganado bovino para carne. Evaluar la fertilidad luego de la IAS en vacas en anestro pretratadas con progesterona más estradiol-17b y ovulación inducida con un destete de 48 h y GnRH.

Materiales de interés tecnológico

Este es un proyecto que tiene por objetivo general dar continuidad a las investigaciones relacionadas a materiales de interés tecnológico que el Grupo Ciencia de Materiales de Fa.M.A.F lleva a cabo. Las diferentes líneas de trabajo se pueden agrupar en tres grandes temas: aceros y superaleaciones basadas en Fe y Ni; cerámicos magnéticos [filtros moleculares de sílice del tipo ZSM-5, MCM-41 y MCM-48 modificados con Fe, Co, Mn; hematita nanométrica] y aleaciones metálicas magnéticas [CoCu, nanohilos y multicapas de CoM y FeM (M= Pt y Pd); aleaciones de tipo Heusler Mn-Ni-Ga, aleaciones CoSiB y FeSiB nanoestructuradas ]. El primer tema apunta a la optimización de las propiedades mecánicas de aceros de medio carbono y baja aleación, de producción nacional y aptos para construcciones mecánicas, y al desarrollo de superaleaciones (Fe,Ni) de alta temperatura, para su aplicación en pequeñas Turbomáquinas Térmicas. En el caso de materiales magnéticos cerámicos y metálicos, el objetivo es la producción y el desarrollo de nanoestructuras novedosas, con propiedades especiales, de potencial uso en nano-dispositivos y nanotecnología en general. En todos los casos se plantea la producción del material de interés a escala laboratorio, con control de las variables del proceso, la caracterización de la microestructura resultante y sus propiedades relevantes. Luego se establecen las correlaciones proceso-microestructura y microestructura–propiedades y se formalizan en modelos para los diferentes mecanismos que operan tanto durante la etapa de proceso (modelos de solidificación, de deposición, de aleado mecánico) como los involucrados en las propiedades de interés (modelos de magnetización, transporte, deformación). En este esquema se busca optimizar las propiedades. El presente proyecto fortalecerá además el área Ciencia de Materiales en la Universidad Nacional de Córdoba, formando en el nivel de grado y posgrado a ingenieros y físicos en esta disciplina. En el área de materiales cerámicos magnéticas nos dedicaremos (en colaboración con CiTeQ-UTN-FRC) a la producción y caracterización de filtros moleculares de sílice de amplio uso en procesos de catálisis, modificados por la incorporación de especies magnéticas. La incorporación del material magnético se realizará mediante técnicas hidrotérmicas y de impregnación. Los composites obtenidos se estudiarán con dos propósitos: evaluar los efectos de la funcionalización magnética sobre el desempeño del filtro de sílice como catalizador de diferentes reacciones y describir las propiedades magnéticas de las pequeñas (2 a 5 nm) nanoestructuras encapsuladas en los poros. Se continuará con la producción y caracterización de partículas de ferritas, con propiedades determinadas a partir del control de los distintos parámetros que intervienen en la síntesis. En la línea de aleaciones metálicas magnéticas se estudiarán las aleaciones de Heusler, con memoria de forma magnetica, las aleaciones CuCo con magneto-resistencia gigante y las aleaciones (Co,Fe)SiB con magnetoimpedancia gigante. Se aplicará la técnica de melt spinning con dos rodillos, a la producción de estas aleaciones. En el caso de aceros de medio carbono el plan propuesto apunta a identificar los micromecanismos de deformación y fractura que pueden operar en estas microestructuras. Se realizará el "collar test" con el objetivo de propagar una grieta radialmente hacia el centro del collar y luego poder observar la sección de material que la contiene. Esta serie de experimentos y observaciones permitirán localizar el inicio de la grieta y avanzar sobre la determinación del tipo de partículas que actúan como intermediarios en la propagación. Se espera que estos antecedentes más los resultados metalográficos arrojen luz sobre los mecanismos de fractura del acero IRAM – IAS 15B41

Tolerância de cultivares de trigo (Triticum aestivum L.) ao alumínio e ao manganês: V. influência do alumínio e do manganês e do grau de tolerância a cada elemento na absorção de cálcio

Com base nos parâmetros Vm e Km obtidos de ensaios de cinética de absorção verificou-se a influência do Al e do Mn e do grau de tolerância de cultivares de trigo a cada um desses elementos sobre a absorção de Ca. Utilizaram-se raízes destacadas de plantas com 7 dias de idade de 3 cultivares com tolerância diferencial ao Al (Sonora 63C - suscetível; Yecora - intermediária e IAS 63 - tolerante) e de 3 cultivares com tolerância diferencial ao Mn (CNTl - suscetível; Sonora 63C - intermediária e IAS 55 - tolerante). Foram empregadas 10 soluções experimentais cujas concentrações de CaCl variaram de 5xl0-6M até 2,56xl0-3M, marcadas com 45Ca. Nos ensaios efetuados na presença de Al ou Mn, usaram-se concentrações de 10-4M de AlCl3 ou MnCl2. Os resultados propiciaram as seguintes -conclusões: a) a absorção de Ca se realiza através de 2 mecanismos, um operativo na faixa 1 de concentração de Ca (5x10-6M - 8 x 10-5M) e outro na faixa 2 de concentração (1,6x10-4M - 2,56 x 10-3M); b) na faixa 1 de concentração de Ca a Al e o Mn inibem a absorção do Ca e na faixa 2 inibem ou estimulam a absorção dependendo do cultivar; c) na ausência de Al ou de Mn existem diferenças genéticas na absorção de Ca somente na faixa 2 de concentração de Ca e estas não estão relacionadas com o grau de tolerância ao Al e ao Mn; d) na presença de Al não existem diferenças genéticas na absorção do Ca na faixa 1 de concentração de Ca, porém existem relacionadas ao grau de tolerância ao Al na faixa 2; e) na presença de Mn existem diferenças genéticas na absorção de Ca em ambas as faixas, porém somente na faixa 1 relacionadas ao grau de tolerância ao Mn.

Tolerância de cultivares de trigo (Triticum aestivum L.) ao alumínio e ao manganês: VI. influência do alumínio e do manganês e do grau de tolerância a cada elemento na absorção do fósforo

Com base nos parâmetros Vm e Km obtidos de ensaios de cinética de absorção, verificou-se a influencia do Al e do Mn e do grau de tolerância de cultivares de trigo a cada um desses elementos sobre a absorção de P. Utilizaram-se raízes destacadas de plantas com 7 dias de idade de 3 cultivares com tolerância diferencial ao Al (Sonora 63C - suscetível; Yecora - intermediária e IAS 63 - tolerante) e de 3 cultivares com tolerância diferencial ao Mn (CNTl -suscetível; Sonora 63C - intermediária e IAS 55 - tolerante). Foram empregadas 10 soluções experimentais cujas concentrações de KH2PO4 variaram de 10-6M até 10-4M, marcadas com 32P. Nos ensaios efetuados na presença de Al ou Mn, usaram-se concentrações de 10-4M de AlCl3 ou MnCl2. Concluiu-se que: a) a absorção de P se realiza através de um único mecanismo; b) na ausência ou presença de Al ou de Mn existem diferenças genéticas na absorção do P nao relacionadas com o grau de tolerância aos 2 elementos; 2) o Al e o Mn, mais aquele do que este, estimulam a absorção do P.

IFRS adoption in Europe: the case of Germany

From 2005 onwards, consolidated financial statements of listed European companies will have to comply with IFRS (IAS). Many German companies began adopting those standards in the 1990s, on a voluntary basis, because of their need to access international capital funding. Spanish companies, by contrast, are not permitted to adopt IFRS before 2005. This paper has two purposes: first, it analyses the financial impact of initial IFRS adoption on the statement of changes in equity and the income statement of individual German companies. Second, and taking into account the German experience, it focuses on the expected impacts on a sample of listed Spanish companies in two industrial sectors: chemical-pharmaceutical and fashion. Our analysis of German companies comprised all non-financial DAX groups applying IFRS plus additional listed companies in the two selected industrial sectors identified above. The impact of initial adoption of IFRS on German companies was, both individually and overall, very significant. The analysis suggests that the expected impact on Spanish companies is likely to be significant but to a lesser degree than in respect of the German companies in the study.

New methods for detecting antibiotic resistant bacteria and preventing their spread

Methicillin resistant Staphylococcus aureus (MRSA) bacteria have emerged in the early 1980's in numerous health care institutions around the world. The main transmission mechanism within hospitals and healthcare facilities is through the hands of health care workers. Resistant to several antibiotics, the MRSA is one of the most feared pathogens in the hospital setting since it is very difficult to eradicate with the standard treatments. There are still a limited number of anti-MRSA antibiotics but the first cases of resistance to these compounds have already been reported and their frequency is likely to increase in the coming years. Every year, the MRSA infections result in major human and financial costs, due to the high associated mortality and expenses related to the required care. Measures towards a faster detection of resistant bacteria and establishment of appropriate antibiotic treatment parameters are fundamental. Also as part as infection prevention, diminution of bacteria present on the commonly touched surfaces could also limit the spread and selection of antibiotic resistant bacteria. During my thesis, projects were developed around MRSA and antibiotic resistance investigation using innovative technologies. The thesis was subdivided in three main parts with the use of atomic force microscopy AFM for antibiotic resistance detection in part 1, the importance of the bacterial inoculum size in the selection of antibiotic resistance in part 2 and the testing of antimicrobial surfaces creating by sputtering copper onto polyester in part 3. In part 1 the AFM was used two different ways, first for the measurement of stiffness (elasticity) of bacteria and second as a nanosensor for antibiotic susceptibility testing. The stiffness of MRSA with different susceptibility profiles to vancomycin was investigated using the stiffness tomography mode of the AFM and results have demonstrated and increased stiffness in the vancomycin resistant strains that also paralleled with increased thickness of the bacterial cell wall. Parts of the AFM were also used to build a new antibiotic susceptibility-testing device. This nano sensor was able to measure vibrations emitted from living bacteria that ceased definitively upon antibiotic exposure to which they were susceptible but restarted after antibiotic removal to which they were resistant, allowing in a matter of minute the assessment of antibiotic susceptibility determination. In part 2 the inoculum effect (IE) of vancomycin, daptomycin and linezolid and its importance in antibiotic resistance selection was investigated with MRSA during a 15 days of cycling experiment. Results indicated that a high bacterial inoculum and a prolonged antibiotic exposure were two key factors in the in vitro antibiotic resistance selection in MRSA and should be taken into consideration when choosing the drug treatment. Finally in part 3 bactericidal textile surfaces were investigated against MRSA. Polyesters coated after 160 seconds of copper sputtering have demonstrated a high bactericidal activity reducing the bacterial load of at least 3 logio after one hour of contact. -- Au cours des dernières décennies, des bactéries multirésistantes aux antibiotiques (BMR) ont émergé dans les hôpitaux du monde entier. Depuis lors, le nombre de BMR et la prévalence des infections liées aux soins (IAS) continuent de croître et sont associés à une augmentation des taux de morbidité et de mortalité ainsi qu'à des coûts élevés. De plus, le nombre de résistance à différentes classes d'antibiotiques a également augmenté parmi les BMR, limitant ainsi les options thérapeutiques disponibles lorsqu'elles ont liées a des infections. Des mesures visant une détection plus rapide des bactéries résistantes ainsi que l'établissement des paramètres de traitement antibiotiques adéquats sont primordiales lors d'infections déjà présentes. Dans une optique de prévention, la diminution des bactéries présentes sur les surfaces communément touchées pourrait aussi freiner la dissémination et l'évolution des bactéries résistantes. Durant ma thèse, différents projets incluant des nouvelles technologies et évoluant autour de la résistance antibiotique ont été traités. Des nouvelles technologies telles que le microscope à force atomique (AFM) et la pulvérisation cathodique de cuivre (PCC) ont été utilisées, et le Staphylococcus aureus résistant à la méticilline (SARM) a été la principale BMR étudiée. Deux grandes lignes de recherche ont été développées; la première visant à détecter la résistance antibiotique plus rapidement avec l'AFM et la seconde visant à prévenir la dissémination des BMR avec des surfaces crées grâce à la PCC. L'AFM a tout d'abord été utilisé en tant que microscope à sonde locale afin d'investiguer la résistance à la vancomycine chez les SARMs. Les résultats ont démontré que la rigidité de la paroi augmentait avec la résistance à la vancomycine et que celle-ci corrélait aussi avec une augmentation de l'épaisseur des parois, vérifiée grâce à la microscopie électronique. Des parties d'un AFM ont été ensuite utilisées afin de créer un nouveau dispositif de test de sensibilité aux antibiotiques, un nanocapteur. Ce nanocapteur mesure des vibrations produites par les bactéries vivantes. Après l'ajout d'antibiotique, les vibrations cessent définitivement chez les bactéries sensibles à l'antibiotique. En revanche pour les bactéries résistantes, les vibrations reprennent après le retrait de l'antibiotique dans le milieu permettant ainsi, en l'espace de minutes de détecter la sensibilité de la bactérie à un antibiotique. La PCC a été utilisée afin de créer des surfaces bactéricides pour la prévention de la viabilité des BMR sur des surfaces inertes. Des polyesters finement recouverts de cuivre (Cu), connu pour ses propriétés bactéricides, ont été produits et testés contre des SARMs. Une méthode de détection de viabilité des bactéries sur ces surfaces a été mise au point, et les polyesters obtenus après 160 secondes de pulvérisation au Cu ont démontré une excellente activité bactéricide, diminuant la charge bactérienne d'au moins 3 logio après une heure de contact. En conclusion, l'utilisation de nouvelles technologies nous a permis d'évoluer vers de méthodes de détection de la résistance antibiotique plus rapides ainsi que vers le développement d'un nouveau type de surface bactéricide, dans le but d'améliorer le diagnostic et la gestion des BMR.

Cardiovascular risk estimation and eligibility for statin therapy using different scoring systems in Europe: a population-based study in Switzerland

BACKGROUND: Recommendations for statin use for primary prevention of coronary heart disease (CHD) are based on estimation of the 10- year CHD risk. We compared the 10-year CHD risk assessments and eligibility percentages for statin therapy using three scoring algorithms currently used in Europe. METHODS: We studied 5683 women and men, aged 35-75, without overt cardiovascular disease (CVD), in a population-based study in Switzerland. We compared the 10-year CHD risk using three scoring schemes, i.e., the Framingham risk score (FRS) from the U.S. National Cholesterol Education Program's Adult Treatment Panel III (ATP III), the PROCAM scoring scheme from the International Atherosclerosis Society (IAS), and the European risk SCORE for low-risk countries, without and with extrapolation to 60 years as recommended by the European Society of Cardiology guidelines (ESC). With FRS and PROCAM, high-risk was defined as a 10- year risk of fatal or non-fatal CHD>20% and a 10-year risk of fatal CVD≥5% with SCORE. We compared the proportions of high-risk participants and eligibility for statin use according to these three schemes. For each guideline, we estimated the impact of increased statin use from current partial compliance to full compliance on potential CHD deaths averted over 10 years, using a success proportion of 27% for statins. RESULTS: Participants classified at high-risk (both genders) were 5.8% according to FRS and 3.0% to the PROCAM, whereas the European risk SCORE classified 12.5% at high-risk (15.4% with extrapolation to 60 years). For the primary prevention of CHD, 18.5% of participants were eligible for statin therapy using ATP III, 16.6% using IAS, and 10.3% using ESC (13.0% with extrapolation) because ESC guidelines recommend statin therapy only in high-risk subjects. In comparison with IAS, agreement to identify eligible adults for statins was good with ATP III, but moderate with ESC. Using a population perspective, a full compliance with ATP III guidelines would reduce up to 17.9% of the 24′ 310 CHD deaths expected over 10 years in Switzerland, 17.3% with IAS and 10.8% with ESC (11.5% with extrapolation). CONCLUSIONS: Full compliance with guidelines for statin therapy would result in substantial health benefits, but proportions of high-risk adults and eligible adults for statin use varied substantially depending on the scoring systems and corresponding guidelines used for estimating CHD risk in Europe.

Description of Leishmania (Leishmania) forattinii sp. n., a new parasite infecting opossums and rodents in Brazil

A new parasite species of Leishmania is described, L. (Leishmania) forattinii sp. n., which was isolated from a pooled triturate of liver and spleen of a opossum (Didelphis marsupialis aurita) and from skin samples from a rodent (Proechmys iheringi denigratus), captured in primary forest on the Atlantic Cost of Brazil. Our results on the basis of biological and molecular criteria indicate that this taxonomically distinct parasite ias a new species of the L. mexicana complex, but closely related to L. (L.) aristidesi Laison & shaw, 1979, as revelated by phenetic and phylogenetic numerical analyses of the enzyme data. L. forattinii was clearly distinguishable from other Leishmania species of the genus usisng enzyme electrophoresis, monoclonal antibodies, molecular karyotypes, analysis of restriction enzyme digestion patterns of kinetoplast DNA (kDNA), as well as the use of kDNA hybridization procedures.

Eligibility for statin therapy in primary prevention: discrepancies using different guidelines in a population-based study in Switzerland

Introduction: Recommendations for statin use for primary prevention of coronary heart disease (CHD) are based on estimation of the 10-year CHD risk. We compared the 10-year CHD risk assessments and eligibility percentages for statin therapy using three scoring algorithms currently used in Switzerland. Methods: We studied 5683 women and men, aged 35-75, without overt cardiovascular disease (CVD), in a population-based study in Lausanne, Switzerland. We compared the 10-year CHD risk using three scoring schemes, i.e., the Framingham risk score (FRS) from the U.S. National Cholesterol Education Program's Adult Treatment Panel III (ATP III), the PROCAM scoring scheme from the International Atherosclerosis Society (IAS), and the European risk SCORE for low-risk countries, without and with extrapolation to 60 years as recommended by the European Society of Cardiology guidelines (ESC). With FRS and PROCAM, high-risk was defined as a 10-year risk of fatal or non-fatal CHD >20% and a 10-year risk of fatal CVD >= 5% with SCORE. We compared the proportions of high-risk participants and eligibility for statin use according to these three schemes. For each guideline, we estimated the impact of increased statin use from current partial compliance to full compliance on potential CHD deaths averted over 10 years, using a success proportion of 27% for statins. Results: Participants classified at high-risk (both genders) were 5.8% according to FRS and 3.0% to the PROCAM, whereas the European risk SCORE classified 12.5% at high-risk (15.4% with extrapolation to 60 years). For the primary prevention of CHD, 18.5% of participants were eligible for statin therapy using ATP III, 16.6% using IAS, and 10.3% using ESC (13.0% with extrapolation) because ESC guidelines recommend statin therapy only in high-risk subjects. In comparison with IAS, agreement to identify eligible adults for statins was good with ATP III, but moderate with ESC (Figure). Using a population perspective, a full compliance with ATP III guidelines would reduce up to 17.9% of the 24'310 CHD deaths expected over 10 years in Switzerland, 17.3% with IAS and 10.8% with ESC (11.5% with extrapolation). Conclusion: Full compliance with guidelines for statin therapy would result in substantial health benefits, but proportions of high-risk adults and eligible adults for statin use varied substantially depending on the scoring systems and corresponding guidelines used for estimating CHD risk in Switzerland.

A comparison of initial antiretroviral therapy in the Swiss HIV Cohort Study and the recommendations of the International AIDS Society-USA.

BACKGROUND: In order to facilitate and improve the use of antiretroviral therapy (ART), international recommendations are released and updated regularly. We aimed to study if adherence to the recommendations is associated with better treatment outcomes in the Swiss HIV Cohort Study (SHCS). METHODS: Initial ART regimens prescribed to participants between 1998 and 2007 were classified according to IAS-USA recommendations. Baseline characteristics of patients who received regimens in violation with these recommendations (violation ART) were compared to other patients. Multivariable logistic and linear regression analyses were performed to identify associations between violation ART and (i) virological suppression and (ii) CD4 cell count increase, after one year. RESULTS: Between 1998 and 2007, 4189 SHCS participants started 241 different ART regimens. A violation ART was started in 5% of patients. Female patients (adjusted odds ratio aOR 1.83, 95%CI 1.28-2.62), those with a high education level (aOR 1.49, 95%CI 1.07-2.06) or a high CD4 count (aOR 1.53, 95%CI 1.02-2.30) were more likely to receive violation ART. The proportion of patients with an undetectable viral load (<400 copies/mL) after one year was significantly lower with violation ART than with recommended regimens (aOR 0.54, 95% CI 0.37-0.80) whereas CD4 count increase after one year of treatment was similar in both groups. CONCLUSIONS: Although more than 240 different initial regimens were prescribed, violations of the IAS-USA recommendations were uncommon. Patients receiving these regimens were less likely to have an undetectable viral load after one year, which strengthens the validity of these recommendations.

A dynamic assessment of medication-taking behavior during pregnancy and postpartum: should cART adherence be reinforced during postpartum?

This study compared adherence (persistence and execution) during pregnancy and postpartum in HIV-positive women having taken part in the adherence-enhancing program of the Community Pharmacy of the Department of Ambulatory Care and Community Medicine in Lausanne between 2004 and 2012. This interdisciplinary program combined electronic drug monitoring and semi-structured, repeated motivational interviews. This was a retrospective, observational study. Observation period spread over from first adherence visit after last menstruation until 6 months after childbirth. Medication-taking was recorded by electronic drug monitoring. Socio-demographic and delivery data were collected from Swiss HIV Cohort database. Adherence data, barriers and facilitators were collected from pharmacy database. Electronic data were reconciled with pill-count and interview notes in order to include reported pocket-doses. Execution was analyzed over 3-day periods by a mixed effect logistic model, separating time before and after childbirth. This model allowed us to estimate different time slopes for both periods and to show a sudden fall associated with childbirth. Twenty-five pregnant women were included. Median age was 29 (IQR: 26.5, 32.0), women were in majority black (n_17,68%) and took a cART combining protease and nucleoside reverse transcriptase inhibitors (n_24,96%). Eleven women (44%) were ART-naı¨ve at the beginning of pregnancy. Twenty women (80%) were included in the program because of pregnancy. Women were included at all stages of pregnancy. Six women (24%) stopped the program during pregnancy, 3 (12%) at delivery, 4 (16%) during postpartum and 12 (48%) stayed in program at the end of observation time. Median number of visits was 4 (3.0, 6.3) during pregnancy and 3 (0.8, 6.0) during postpartum. Execution was continuously high during pregnancy, low at beginning of postpartum and increased gradually during the 6 months of postpartum. Major barriers to adherence were medication adverse events and difficulties in daily routine. Facilitators were motivation for promoting child-health and social support. The dramatic drop and very slow increase in cART adherence during postpartum might result in viral rebound and drug resistance. Although much attention is devoted to pregnant women, interdisciplinary care should also be provided to women in the community during first trimester of postpartum to support them in sustaining cART adherence.
