RESUMO

Suicide negatively impacts societies worldwide. A particular area of concern is the prevalence of suicide among Latinx youth, as research indicates that suicide behaviors among Latinx in the United States and youth in Latin America have increased drastically over the last decade. Reducing suicide stigma is a key factor in promoting youth help-seeking behaviors regarding suicidality. Previous research suggests that a relationship with a trusted adult may influence the likelihood of an adolescent contacting a suicide crisis line. Our study seeks to further the research of how parents can influence youth perceptions of suicide by studying the relationship between parent and child suicide stigma. Data were collected from parent-child dyads throughout Mexico. The Stigma of Suicide Scale Short Form was used to measure suicide stigma among adult and youth participants independently. Results suggest that parent suicide stigma was a significant predictor of youth suicide stigma, that male youth in our sample had higher suicide stigma than female youth, and that access to healthcare services was associated with lower suicide stigma. Results are discussed considering unique cultural factors in Mexico such as familismo. If future research reinforces the findings of this study, suicide stigma programs might be more effective if targeted at the entire family unit rather than just adolescents.

RESUMO

Research suggests that health literacy (HL) is critical in preventing and managing health problems. However, over half of adults in Mexico report having inadequate health literacy. Research suggests the parent-child relationship can be a key predictor of developmental competencies; however, little research has examined how dyadic family interactions relate to HL. This study examined whether parent-child relationship conflict was associated with adolescent health literacy among families living in Mexico. Data from a parent-child dyads in Mexico were gathered using online surveys (N = 746, 373 parent-child dyads). Our findings suggested that child-reported family conflict-but not parent-reported family conflict - was associated with lower adolescent health literacy. Researchers and practitioners should consider how parent-child conflict may impact adolescent health outcomes, and prioritise child reports in data collection.

RESUMO

OBJECTIVES: The authors sought to evaluate the incidence, predictors, and outcomes of new permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR) with contemporary self-expanding valves (SEV). BACKGROUND: Need for PPI is frequent post-TAVR, but conflicting data exist on new-generation SEV and on the prognostic impact of PPI. METHODS: This study included 3,211 patients enrolled in the multicenter NEOPRO (A Multicenter Comparison of Acurate NEO Versus Evolut PRO Transcatheter Heart Valves) and NEOPRO-2 (A Multicenter Comparison of ACURATE NEO2 Versus Evolut PRO/PRO+ Transcatheter Heart Valves 2) registries (January 2012 to December 2021) who underwent transfemoral TAVR with SEV. Implanted transcatheter heart valves (THV) were Acurate neo (n = 1,090), Acurate neo2 (n = 665), Evolut PRO (n = 1,312), and Evolut PRO+ (n = 144). Incidence and predictors of new PPI and 1-year outcomes were evaluated. RESULTS: New PPI was needed in 362 patients (11.3%) within 30 days after TAVR (8.8%, 7.7%, 15.2%, and 10.4%, respectively, after Acurate neo, Acurate neo2, Evolut PRO, and Evolut PRO+). Independent predictors of new PPI were Society of Thoracic Surgeons Predicted Risk of Mortality score, baseline right bundle branch block and depth of THV implantation, both in patients treated with Acurate neo/neo2 and in those treated with Evolut PRO/PRO+. Predischarge reduction in ejection fraction (EF) was more frequent in patients requiring PPI (P = 0.014). New PPI was associated with higher 1-year mortality (16.9% vs 10.8%; adjusted HR: 1.66; 95% CI: 1.13-2.43; P = 0.010), particularly in patients with baseline EF <40% (P for interaction = 0.049). CONCLUSIONS: New PPI was frequently needed after TAVR with SEV (11.3%) and was associated with higher 1-year mortality, particularly in patients with EF <40%. Baseline right bundle branch block and depth of THV implantation independently predicted the need of PPI.

RESUMO

BACKGROUND: Transcatheter aortic valve replacement (TAVR) with the ACURATE neo device has been associated with a non-negligible incidence of paravalvular aortic regurgitation (AR). The new-generation ACURATE neo2 has been designed to mitigate this limitation. AIMS: The aim of the study was to compare TAVR with the ACURATE neo and neo2 devices. METHODS: The NEOPRO and NEOPRO-2 registries retrospectively included patients undergoing transfemoral TAVR with self-expanding valves at 24 and 20 centres, respectively. Patients receiving the ACURATE neo and neo2 devices (from January 2012 to December 2021) were included in this study. Predischarge and 30-day VARC-3 defined outcomes were evaluated. The primary endpoint was predischarge moderate or severe paravalvular AR. Subgroup analyses per degree of aortic valve calcification were performed. RESULTS: A total of 2,026 patients (neo: 1,263, neo2: 763) were included. Predischarge moderate or severe paravalvular AR was less frequent for the neo2 group (2% vs 5%; p<0.001), resulting in higher VARC-3 intended valve performance (96% vs 90%; p<0.001). Furthermore, more patients receiving the neo2 had none/trace paravalvular AR (59% vs 38%; p<0.001). The reduction in paravalvular AR with neo2 was mainly observed with heavy aortic valve calcification. New pacemaker implantation and VARC-3 technical and device success rates were similar between the 2 groups; there were more frequent vascular and bleeding complications for the neo device. Similar 1-year survival was detected after TAVR (neo2: 90% vs neo: 87%; p=0.14). CONCLUSIONS: TAVR with the ACURATE neo2 device was associated with a lower prevalence of moderate or severe paravalvular AR and more patients with none/trace paravalvular AR. This difference was particularly evident with heavy aortic valve calcification.

RESUMO

Proliferation of sports coverage in the media over recent decades provides rich material through which to explore a range of socio-cultural issues. A growing number of international studies have focused on questions of gender, while in Brazil the focus has been on (men's) football as the national sport. The success of the women's national team and the global profile that women's football has come to enjoy has led to the first considerations of the ways in which the women's game in Brazil has featured in the country's printed media, especially since 2000. This study will focus instead on the ways in which women's football was discussed and represented in the country's most popular sports magazine during the period when women's football was formally prohibited in order to understand how the visual and textual discourses that have frequently been used to delegitimise women's football came to be established.


A proliferação da cobertura esportiva da mídia durante as últimas décadas oferece um rico material para empreender uma análise de vários temas socioculturais. Um crescente número de estudos internacionais vem se dedicando às questões de gênero, ainda que no Brasil se tenha estudado o futebol masculino como o esporte nacional. O êxito da seleção de mulheres e o perfil global que o futebol feminino conquistou têm resultado no estudo das formas como esta prática tem sido representada na mídia brasileira, sobretudo desde os anos 2000. Este estudo toma como ponto de análise as representações de futebol feminino na revista esportiva mais popular do país, durante os anos nos quais o futebol foi proibido, para entender como se estabelecem os discursos tanto textuais como visuais que serviram com frequência para deslegitimar o futebol praticado por mulheres.

RESUMO

Safety and feasibility of transfemoral Acurate neo implantation without systematic predilatation are not fully investigated. Our aim was to evaluate the use and impact of pre-implantation balloon aortic valvuloplasty (pre-BAV) before transcatheter aortic valve implantation (TAVI) with Acurate neo. The NEOPRO Registry retrospectively included 1,263 patients who underwent transfemoral TAVI with Acurate neo at 18 centers between January 2012 and March 2018. Information on preBAV was available for 1,262 patients (99.9%). Primary endpoints were pre-discharge moderate-tosevere paravalvular aortic regurgitation (PAR II+), 30-day new permanent pacemaker implantation (PPI), and 30-day all-cause mortality or stroke. A total of 1,262 patients who underwent TAVI with (n=1,051) or without predilatation (n=211) were included. A reduction in the pre-BAV rate was observed during the study period (from 95.7% in the first date quintile to 78.4% in the last date quintile). Patients who underwent pre-BAV had higher degrees of aortic valve (AV) and left ventricular outflow tract (LVOT) calcification. Primary endpoints were similar between pre-BAV and no pre-BAV groups (PAR II+ 5.5% vs. 3.4%, p=0.214; 30-day PPI 9.0% vs. 8.0%, p=0.660; 30-day death or stroke 4.9% vs. 4.4%, p=0.743). The need for postdilatation and other procedural outcomes were comparable between groups. Predilatation did not have a significant impact on primary endpoints across AV and LVOT calcification subgroups (subgroup analyses) and was not independently associated with primary endpoints (multivariate analyses). In conclusion, transfemoral Acurate neo implantation without predilatation appears to be feasible and safe, especially in patients with milder degrees of AV and LVOT calcification. (AU)

RESUMO

This research report explores the impact of Covid-19 on women's football in Buenos Aires. The suspension of all forms of football in Argentina as part of the country's hard lockdown measures threatens to undo significant gains made in women's football in recent years. By focussing on the experiences of key actors in a feminist Civil Society Organization (CSO) and a newly professional women's team, respectively, we examine what the pandemic has meant for women's football and for women football players at different levels of the game. We also consider the potential impact of the current situation on the future of women's football in Argentina, representative of wider social advances for women in the country.

RESUMO

BACKGROUND: In patients with ST-segment elevation myocardial infarction (STEMI), percutaneous coronary intervention (PCI) of the culprit lesion reduces the risk of cardiovascular death or myocardial infarction. Whether PCI of nonculprit lesions further reduces the risk of such events is unclear. METHODS: We randomly assigned patients with STEMI and multivessel coronary artery disease who had undergone successful culprit-lesion PCI to a strategy of either complete revascularization with PCI of angiographically significant nonculprit lesions or no further revascularization. Randomization was stratified according to the intended timing of nonculprit-lesion PCI (either during or after the index hospitalization). The first coprimary outcome was the composite of cardiovascular death or myocardial infarction; the second coprimary outcome was the composite of cardiovascular death, myocardial infarction, or ischemia-driven revascularization. RESULTS: At a median follow-up of 3 years, the first coprimary outcome had occurred in 158 of the 2016 patients (7.8%) in the complete-revascularization group as compared with 213 of the 2025 patients (10.5%) in the culprit-lesion-only PCI group (hazard ratio, 0.74; 95% confidence interval [CI], 0.60 to 0.91; P=0.004). The second coprimary outcome had occurred in 179 patients (8.9%) in the complete-revascularization group as compared with 339 patients (16.7%) in the culprit-lesion-only PCI group (hazard ratio, 0.51; 95% CI, 0.43 to 0.61; P=0.62 and P=0.27 for interaction for the first and second coprimary outcomes, respectively). CONCLUSIONS: Among patients with STEMI and multivessel coronary artery disease, complete revascularization was superior to culprit-lesion-only PCI in reducing the risk of cardiovascular death or myocardial infarction, as well as the risk of cardiovascular death, myocardial infarction, or ischemia-driven revascularization.

RESUMO

OBJECTIVES: This study sought to evaluate SAPIEN 3 (S3) (Edwards Lifesciences, Irvine, California) positioning using different strategies. BACKGROUND: Aortic valve-in-valve (ViV) is associated with high risk of elevated gradients. METHODS: S3 aortic ViV procedures in stented bioprostheses were studied. Transcatheter heart valve (THV) positioning was analyzed in a centralized core lab blinded to clinical outcomes. A combined endpoint of severely elevated mean gradient ($30 mm Hg) or pacemaker need was established. Two positioning strategies were compared: central marker method and top of S3 method. Optimal final depth was defined as S3 depth #20%. RESULTS: A total of 113 patients met inclusion criteria and were analyzed (76.5 _ 9.7 years of age, 65.8% male, STS score 8 _ 7.6%). THVs had incomplete shortening in comparison to fully expanded valves (92 _ 3.4%), and expansion was more complete in optimal positioning cases compared with others (93.2 _ 2.7% vs. 91.5 _ 3.5%; p » 0.027). The central marker method demonstrated greater correlation with final implantation depth than the top of S3 method (R2 of 0.48 and 0.14; p < 0.001 and p » 0.001, respectively). The combined endpoint rate was 4.3% in the optimal (higher than 3 mm) implantation group, 12% in the intermediate group, and 50% in the low group (p < 0.001). There were no cases of THV embolization. In cases with central marker higher than 3 mm, 72.4% had optimal final depth. In those with central marker higher than 6 mm, 90% had optimal final depth. CONCLUSIONS: Optimal S3 positioning in aortic ViV is associated with better outcomes. Central marker positioning is more reliable than top of S3 positioning. Central marker bottom position should be 3 mm to 6 mm above the ring. (AU)

RESUMO

Abstract OBJECTIVES: The aim of this study was to compare transcatheter aortic valve replacement (TAVR) with the Acurate neo (NEO) and Evolut PRO (PRO) devices. BACKGROUND: The NEO and PRO bioprostheses are 2 next-generation self-expanding devices developed for TAVR. METHODS: The NEOPRO (A Multicenter Comparison of Acurate NEO Versus Evolut PRO Transcatheter Heart Valves) registry retrospectively included patients who underwent transfemoral TAVR with either NEO or PRO valves at 24 centers between January 2012 and March 2018. One-to-one propensity score matching resulted in 251 pairs. Pre-discharge and 30-day Valve Academic Research Consortium (VARC)-2 defined outcomes were evaluated. Binary logistic regression was performed to adjust the treatment effect for propensity score quintiles. RESULTS: A total of 1,551 patients (n = 1,263 NEO; n = 288 PRO) were included. The mean age was 82 years, and the mean Society of Thoracic Surgeons score was 5.1%. After propensity score matching (n = 502), VARC-2 device success (90.6% vs. 91.6%; p = 0.751) and pre-discharge moderate to severe (II+) paravalvular aortic regurgitation (7.3% vs. 5.7%; p = 0.584) were comparable between the NEO and PRO groups. Furthermore, there were no significant differences in any 30-day clinical outcome between matched NEO and PRO pairs, including all-cause mortality (3.2% vs. 1.2%; p = 0.221), stroke (2.4% vs. 2.8%; p = 1.000), new permanent pacemaker implantation (11.0% vs. 12.8%; p = 0.565), and VARC-2 early safety endpoint (10.6% vs. 10.4%; p = 1.000). Logistic regression on the unmatched cohort confirmed a similar risk of VARC-2 device success, paravalvular aortic regurgitation II+, and 30-day clinical outcomes after NEO and PRO implantation. CONCLUSIONS: (AU)

RESUMO

London Dialogue event, The Hospital Club, 24 Endell St, London, WC2H 9HQ, London, UK, 1 December 2015 Hypertension is a global health issue causing almost 10 million deaths annually, with a disproportionate number occurring in low- and middle-income countries. The condition can be managed effectively, but there is a need for innovation in healthcare delivery to alleviate its burden. This paper presents a number of innovative delivery models from a number of different countries, including Kenya, Ghana, Barbados and India. These models were presented at the London Dialogue event, which was cohosted by the Novartis Foundation and the London School of Hygiene & Tropical Medicine Centre for Global Noncommunicable Diseases on 1 December 2015. It is argued that these models are applicable not only to hypertension, but provide valuable lessons to address other noncommunicable diseases.

RESUMO

Budd-Chiari syndrome (BCS) refers to hepatic venous outflow obstruction that in severe cases can lead to acute liver failure prompting consideration of revascularization or transplantation. Here, a 22 year old female with angiographically proven BCS secondary to JAK2/V617F positive Polycythemia vera on therapeutic warfarin presented with acute liver failure (ALF). Imaging revealed a new, near complete thrombotic occlusion of the main portal vein with extension into the superior mesenteric vein. An emergent direct intrahepatic portocaval shunt (DIPS) was created and liver function promptly normalized. She has been maintained on rivaroxaban since that time. Serial assessment over 1 year demonstrated continued shunt patency and improved flow in the mesenteric vasculature on ultrasound as well as normal liver function. DIPS is a viable alternative in the treatment of ALF from BCS when standard recanalization is not feasible. Improved blood flow may also improve portal/mesenteric clot burden. While further investigation is needed, new targeted anticoagulants may be viable as a long term anticoagulation strategy.

RESUMO

Rotavirus vaccines are at an advanced stage of development but there are as yet no WHO recommendations on production and quality control to provide regulatory guidance. A meeting of experts was convened by WHO and PAHO/AMRO to review the scientific basis for production and quality control of rotavirus vaccines, and to discuss specific measures to assure the safety and efficacy of rotavirus vaccines. The meeting was attended by 25 experts from 14 countries, drawn from academia, public health, national regulatory authorities and vaccine producers. It was agreed that existing guidance for other live virus vaccines provides a very good basis for product characterization, especially for source materials and control of production. The basis for attenuation of current vaccines or vaccine candidates is not known but, at least for the vaccines based on the Jennerian approach of using animal (bovine) rotaviruses, is likely to be multigenic. The risk of intussusception in humans is influenced by genetic background and age. Recent analyzes of large vaccine safety trials found that certain strains of vaccine virus were not associated with intussusception, although in these trials the first dose of vaccine was not administered to children over 3 months of age. Since age is a risk factor for intussusception, this may suggest that early delivery of the first dose of vaccine is desirable. However, maternal antibodies may mitigate against early delivery of the first vaccine dose. Factors which could affect vaccine efficacy or safety include strain diversity, malnutrition, other enteric infections, parasitic infection or immune suppression. It was concluded that data from clinical trials conducted in one part of the world would not necessarily be predictive of vaccine efficacy in other places. It was agreed that in nonclinical evaluations there was a need to use oral dosing for toxicity studies and, because rotavirus is non-neurovirulent, that there was no need for an animal neurovirulence test. For clinical evaluations there was a need for a standard definition of severe disease as the clinical endpoint, a need for studies in diverse geographical regions, and the need to control for possible interference by factors such as other oral vaccinations, intercurrent infections and breast feeding. There is no accepted correlate of protection. Secretory IgA is the most satisfactory laboratory parameter currently available and for a period after vaccination much of the specific serum IgA is of this type, so that serum IgA levels can act as measure of seroconversion. The need for standardization of the potency assay for release of vaccine was identified, as was a need to develop guidance on standardized approaches to post-marketing surveillance for rotavirus vaccines.
