title: Left Atrial Appendage Closure with the LAmbre Device – Initial Multicentre Experience in Brazil

description: Abstract Background Left atrial appendage (LAA) closure has been an alternative to oral anticoagulation (OAC) for stroke prevention in patients with non-valvular atrial fibrillation (NVAF). Objectives To report the first results of an initial multicenter experience in Brazil and to investigate the feasibility, safety, and efficacy of LAA closure with the new LAmbre device. Methods We collected procedural and follow-up data of 51 consecutive patients with non-valvular atrial fibrillation, restrictions for long-term OAC and suitable anatomy that underwent LAA closure with the LAmbre device in 18 centers in Brazil. Procedural indications were significant bleeding under OAC (47.1%), stroke or persistent LAA thrombus despite OAC (27.5%), bleeding plus stroke (17.6%), other clinical contraindications for OAC (5.9%), and patient’s choice due to sports practice (1.9%). Results Twenty-five men (49%) and 26 women (51%), with a mean age of 76±7.7 years, mean CHA2DS2-VASc score of 4.6± 1.7 and mean HAS-BLED score of 3.4± 1.1 were studied. Procedural success rate was 100%. Procedure-related immediate complications were pericardial effusion in two patients, and immediate device embolization in one case. No large residual shunts (&gt; 5 mm) were observed, and small shunts (&lt;5mm) were detected in four patients by color Doppler at the end of the procedure. After a mean follow-up of 18 ± 12 months, there were no deaths, strokes nor any other major complications. Conclusion LAA occlusion with the LAmbre device was safe and effective in this small case series. Despite these encouraging initial results, the small number of cases warrants further studies with longer-term follow-up.

title: In vitro toxicity of Niedenzuella (Tetrapterys) multiglandulosa on bovine embryos

description: Abstract Niedenzuella (Tetrapterys) multiglandulosa, a vine plant found in Brazil, has been correlated to outbreaks of poisoning in cattle and buffaloes, generating economic losses related to the death due to heart failure, miscarriage, abortion, stillbirth, and neonatal mortality. The aim of this study was to examine the embryotoxic potential of the aqueous plant extract on in vitro bovine embryos. In vitro study was performed in five replicates of bovine embryo culture assigned in two groups: control, in vitro embryo culture medium without the aqueous plant extract; treated group, with addition of 2.7mg/mL of aqueous plant extract (10%) to the embryo culture on the sixth day of culture. Cleavage rate was evaluated at day 2 of the cell culture. Viability, hatchability and underdevelopment of blastocysts on the seventh, eighth, and ninth days (D7, D8, and D9, respectively) of culture were assessed under stereoscopic microscope. On day 7, blastocysts were submitted to TUNEL assay to determine apoptotic index. In vitro exposure of bovine embryos to of N. multiglandulosa resulted in reduced embryo development and survival, evaluated by dark cytoplasm indicating poor morphology and poor quality with marked reduction of hatchability. We observed a significant reduction of blastocyst production/number of cleaved embryos (60.6% vs 41.5%); reduction of blastocysts production/total number of matured bovine oocytes (35.1% vs 21.3%); and embryonic hatching rates (38.0% vs 10.0%). However, no effects were observed on the apoptotic rate. In conclusion, aqueous extract of N. multiglandulosa leaves reduces bovine embryo viability in vitro, suggesting possible detrimental effects on embryo development.

title: Barriers towards the refugee employment in Brazil and their impacts on long-term integration

description: Abstract This article seeks to analyze how individual, national and organizational barriers and their interrelationships impact the employment of refugees in the Brazilian labor market, based on the theory of the relational structure of diversity management of Syed and Özbilgin (2009). Through an interpretative paradigm, a qualitative approach, and the use of descriptive research, this study was conducted with eight refugees formally employed in the city of São Paulo, Brazil. The findings of this study indicate the prevalence of national barriers over job exclusion for refugees, which may potentiate exclusion factors at the individual and organizational level. The Brazilian government appeared as one of the main national obstacles to integration, playing a particularly important role in the relational structure. This research presents its contributions to regard the refugee’s condition as inherent to an extension of diversity. By shedding light on the perspectives of refugees about the Brazilian organizational reality, the article proposes solutions for policy makers and organizations in order to minimize the impacts that the different barriers provide to the effective integration of these groups in Brazilian organizations.

title: Argentina’s fertility regime (1980-2010): the end of the first demographic transition or an emergent second one?

description: Abstract Argentina’s fertility transition has exceptional characteristics. Compared to most Latin American countries, Argentina’s fertility declined relatively early and, unlike fertility transitions in Western Europe, this decline did not lead to a high period of natural population growth. By the beginning of the twenty-first century, Argentina seemed to experience fertility stagnation despite women’s increased formal education and labor force participation, and increased availability of contraceptives. Using the 1980, 1991, 2001, and 2010 Population Censuses, I demonstrate that fertility has continued its downward trend from 1980 to 2010. Changes in fertility behaviors are given by a decrease in the mean number of children per woman, but not by an increase in childlessness. However, there is evidence of postponement of childbearing. Results show that although Argentina is completing its first demographic transition, as it has not reached below-replacement fertility yet, this country could show signs of an emerging second demographic transition.

title: Emulsifier and enzymatic complex in diet for free range broiler chicken in the western amazon

description: Abstract This study aimed to evaluate the effects of adding levels of emulsifier based on soy lecithin and enzymatic complex (xylanase, β-glucanase, galactosidase, protease, amylase, and β-mannanase) on the basal diet during the raising of free-range broiler chickens. The experimental design was completely randomized, with five treatments and six replications. Treatments were: T1: control diet, without enzymatic complex and emulsifier; T2: 0.2 kg t-1 of enzymatic complex; T3: 0.5 kg t-1 of emulsifier; T4: 0.2 kg t-1 of enzymatic complex + 0.5 kg t-1 of emulsifier; and T5: 0.3 kg t-1 of enzymatic complex + 1 kg t-1 of emulsifier. Performance data were collected every 14 days, and the animals were euthanized at 70 days to obtain carcass, breast, drumstick, and thigh yield and intestine collection for pH analysis and morphometry. The periods from 1 to 56 and 1 to 70 days showed a difference (P&lt;0.05) in the parameters of zootechnical performance, the feed intake was lower in T4 and T5, and weight gain was better in T1, T2, T3, and T4. Feed conversion was better in T1, T2, and T4. No difference (P&gt;0.05) was observed for poultry livability, carcass yield, viscera, and pH of duodenum and cecum. A difference was found for intestinal morphometry (P&lt;0.05), and T5 showed the best villus/crypt ratio. The level with 0.3 kg t-1 of enzymatic complex and 1 kg t-1 of emulsifier indicated a better relationship between villi and crypts. However, the level with 0.2 kg t-1 of enzymatic complex and 0.5 kg t-1 of emulsifier added to the commercial diet led to benefits such as decreased feed intake, without affecting weight gain, thus inducing a good feed conversion.

title: Digital activism and democratic culture: can digital technologies help save democracy?

description: This study investigates digital activism and democratic culture among citizens of São Paulo, Brazil. It aims to understand: 01. whether digital participation is becoming a surrogate instance of other forms of participation; and 02. whether digital activists share a specific political culture regarding democratic attitudes and behaviors. Drawing on a representative sample of 2,417 interviews, we apply multivariate analysis techniques to characterize digital activists in terms of political participation and democratic culture. Our findings show that digital participation complements – rather than replaces – other forms of participation. We also found that although the levels of democratic culture among digital-only activists were lower than among activists who participate in several arenas, digital-only activists embrace democratic culture more significantly than non-activists. This finding suggests that digital-only participation could be an important first step in developing democratic attitudes in individuals, albeit this form of participation is not sufficient to foster the highest level of democratic culture.

title: Relationship between Systemic Immune-Inflammation Index and Coronary Collateral Circulation in Patients with Chronic Total Occlusion

description: Abstract Background Inflammation plays a key role in the initiation and progression of coronary artery disease (CAD). The systemic immune-inflammation index (SII) is a novel inflammatory parameter that has been shown to be associated with CAD. Objective This study aimed to investigate the relationship between SII and coronary collateral circulation (CCC) in patients with stable CAD and chronic total occlusion (CTO). Methods The patients were divided into two groups, with poor CCC and good CCC, according to the Rentrop Classification. Ninety-four patients had poor CCC, and 81 patients had good CCC. Inflammation parameters were calculated from the laboratory results. The statistical significance level applied was 0.05. Results High SII level (OR: 1.003, 95% CI: 1.001-1.004, p&lt;0,001), absence of CTO in RCA (OR: 0.204, 95% CI: 0.096-0.436, p&lt;0,001) and low Gensini score (OR: 0.980, 95% CI: 0.962-0.998, p=0,028) were significantly associated with poor CCC. The cutoff value of SII was 679.96 for the highest predictive power of poor CCC, with a sensitivity of 74.5% and specificity of 43.2%. Mortality rates were similar between the two groups during a mean follow-up of 21.5±10.8 months (p=0.107). Conclusions High SII level, the absence of CTO in the right coronary artery, and low Gensini score were significantly related to poor CCC. The rapid and cost-effective use of new inflammatory markers in clinical practice guides the prognosis of CAD.
