RESUMEN
PURPOSE: We aimed to conduct a systematic review and meta-analysis to assess the effects of anemia and anemia severity on patient outcomes in cardiac surgery and determine whether preoperative treatments confer postoperative benefit. SOURCE: We searched four international databases for observational and randomized studies published until 1 October 2022. Study quality was assessed via Newcastle-Ottawa scores and the Cochrane Risk-of-Bias 2 tool and certainty of evidence was rated with the Grading of Recommendations, Assessment, Development and Evaluations approach. We conducted random-effects meta-analyses for our primary outcome of mortality, for secondary outcomes including length of stay (LOS) in the hospital and intensive care unit, and for postsurgical complications. As part of a secondary analysis, we analyzed short-term preoperative anemia treatments and conducted trial sequential analysis of randomized trials to assess the efficacy of these treatment programs. PRINCIPAL FINDINGS: We included 35 studies (159,025 patients) in our primary meta-analysis. Preoperative anemia was associated with increased mortality (odds ratio [OR], 2.5; 95% confidence interval [CI], 2.2 to 2.9; P < 0.001, high certainty). Study-level meta-regression revealed lower hemoglobin levels and studies with lower proportions of male patients to be associated with increased risk of mortality. Preoperative anemia was also associated with an increase in LOS and postsurgical complications. Our secondary analysis (seven studies, 1,012 patients) revealed short-term preoperative anemia treatments did not significantly reduce mortality (OR, 1.1; 95% CI, 0.65 to 1.9; P = 0.69). Trial sequential analysis suggested that there was insufficient evidence to conclude if treatment programs yield any benefit or harm. CONCLUSIONS: Preoperative anemia is associated with mortality and morbidity after cardiac surgery. More research is warranted to test the efficacy of current anemia treatment programs.

RéSUMé: OBJECTIF: Notre objectif était de mener une revue systématique et une méta-analyse pour évaluer les effets de l'anémie et de la gravité de l'anémie sur les devenirs des patient·es en chirurgie cardiaque et déterminer si les traitements préopératoires conféraient un bénéfice postopératoire. SOURCES: Nous avons réalisé des recherches dans quatre bases de données internationales pour en extraire des études observationnelles et randomisées publiées jusqu'au 1er octobre 2022. La qualité des études a été évaluée à l'aide des scores de Newcastle-Ottawa et de l'outil Cochrane 2 sur le risque de biais, et la certitude des données probantes a été évaluée selon l'approche GRADE (Grading of Recommendations, Assessment, Development and Evaluations). Nous avons réalisé des méta-analyses à effets aléatoires pour notre critère d'évaluation principal de mortalité, pour les critères d'évaluation secondaires, notamment la durée du séjour à l'hôpital et à l'unité de soins intensifs, et pour les complications postopératoires. Dans le cadre d'une analyse secondaire, nous avons examiné les traitements préopératoires de l'anémie à court terme et effectué une analyse séquentielle d'études randomisées afin d'évaluer l'efficacité de ces modalités de traitement. CONSTATATIONS PRINCIPALES: Nous avons inclus 35 études portant sur 159 025 patient·es dans notre méta-analyse. L'anémie préopératoire était associée à une augmentation de la mortalité (rapport de cotes [RC], 2,5; intervalle de confiance [IC] à 95 %, 2,2 à 2,9; P < 0,001, certitude élevée). La méta-régression au niveau de l'étude a révélé que des taux d'hémoglobine plus faibles et des études avec des proportions plus faibles de patients masculins étaient associées à un risque accru de mortalité. L'anémie préopératoire était également associée à une augmentation de la durée de séjour et des complications postopératoires. Notre analyse secondaire (sept études, 1012 patient·es) a révélé que les traitements préopératoires de l'anémie à court terme ne réduisaient pas significativement la mortalité (RC, 1,1; IC 95 %, 0,65 à 1,9; P = 0,69). L'analyse séquentielle des études a suggéré qu'il n'y avait pas suffisamment de données probantes pour conclure si les modalités de traitement entraînaient un bénéfice ou un préjudice. CONCLUSION: L'anémie préopératoire est associée à la mortalité et à la morbidité après une chirurgie cardiaque. D'autres recherches sont justifiées pour tester l'efficacité des programmes actuels de traitement de l'anémie.

PURPOSE: Cardiogenic shock is associated with high mortality. In refractory shock, it is unclear if mechanical circulatory support (MCS) devices improve survival. We conducted a network meta-analysis to determine which MCS devices confers greatest benefit. METHODS: We searched MEDLINE, Embase, and Scopus databases through 27 August 2023 for relevant randomized controlled trials (RCTs) and propensity score-matched studies (PSMs). We conducted frequentist network meta-analysis, investigating mortality (either 30 days or in-hospital) as the primary outcome. We assessed risk of bias (Cochrane risk of bias 2.0 tool/Newcastle-Ottawa Scale) and as sensitivity analysis reconstructed survival data from published survival curves for a one-stage unadjusted individual patient data (IPD) meta-analysis using a stratified Cox model. RESULTS: We included 38 studies (48,749 patients), mostly reporting on patients with Society for Cardiovascular Angiography and Intervention shock stages C-E cardiogenic shock. Compared with no MCS, extracorporeal membrane oxygenation with intra-aortic balloon pump (ECMO-IABP; network odds ratio [OR]: 0.54, 95% confidence interval (CI): 0.33-0.86, moderate certainty) was associated with lower mortality. There were no differences in mortality between ECMO, IABP, microaxial ventricular assist device (mVAD), ECMO-mVAD, centrifugal VAD, or mVAD-IABP and no MCS (all very low certainty). Our one-stage IPD survival meta-analysis based on the stratified Cox model found only ECMO-IABP was associated with lower mortality (hazard ratio, HR, 0.55, 95% CI 0.46-0.66). CONCLUSION: In patients with cardiogenic shock, ECMO-IABP may reduce mortality, while other MCS devices did not reduce mortality. However, this must be interpreted within the context of inter-study heterogeneity and limited certainty of evidence.

Introduction: Colorectal cancer screening when done early can significantly reduce mortality. However, screening compliance is still lower than expected even in countries with established screening programs. Motivational interviewing is an approach that has been explored to promote behavioral change including screening compliance. This review synthesizes the efficacy of motivational interviewing in promoting uptake of colorectal screening modalities and is the only review so far that examines motivational interviewing for colorectal cancer screening alone. Methods: A systematic review and meta-analysis was conducted to examine the effects of motivational interviewing for colorectal cancer screening. PubMed, EMBASE, CENTRAL, PsycINFO, and CINAHL were searched to identify eligible studies from inception to June 2021 and selection criteria was defined. Risk of bias was assessed using the Cochrane Risk of Bias 2.0 tool. The DerSimonian and Laird random effects model was used in the statistical analysis for studies included in the meta-analysis. Results: Fourteen studies from 14 randomized-controlled trials with a low to moderate risk of bias were analyzed. 8 studies in the systematic review showed that motivational interviewing is superior to a control group. Meta-analysis was conducted on 11 studies and showed that motivational interviewing is statistically significant in increasing colorectal cancer screening rates in both intention-to-treat and per-protocol analysis. Timing of data collection of colorectal cancer screening rates did not make a significant difference to the efficacy of motivational interviewing. Studies that offered and accepted a mixture of colorectal screening modalities such as colonoscopy and fecal immunochemical tests were significantly more likely to have favorable colorectal screening outcomes. Heterogeneity in intervention was noted between studies, specifically differences in the training of interventionists, intervention delivery and comparator components. Conclusion: Motivational interviewing is a tailored intervention demonstrating mixed evidence in improving colorectal cancer screening attendance amongst individuals. More research is needed to rigorously compare the effect of motivational interviewing alone vs. in combination with other screening promotion strategies to enhance colorectal cancer screening compliance.
RESUMEN
We report the discovery and translational therapeutic efficacy of a peptide with potent, balanced co-agonism at both of the receptors for the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). This unimolecular dual incretin is derived from an intermixed sequence of GLP-1 and GIP, and demonstrated enhanced antihyperglycemic and insulinotropic efficacy relative to selective GLP-1 agonists. Notably, this superior efficacy translated across rodent models of obesity and diabetes, including db/db mice and ZDF rats, to primates (cynomolgus monkeys and humans). Furthermore, this co-agonist exhibited synergism in reducing fat mass in obese rodents, whereas a selective GIP agonist demonstrated negligible weight-lowering efficacy. The unimolecular dual incretins corrected two causal mechanisms of diabesity, adiposity-induced insulin resistance and pancreatic insulin deficiency, more effectively than did selective mono-agonists. The duration of action of the unimolecular dual incretins was refined through site-specific lipidation or PEGylation to support less frequent administration. These peptides provide comparable pharmacology to the native peptides and enhanced efficacy relative to similarly modified selective GLP-1 agonists. The pharmacokinetic enhancement lessened peak drug exposure and, in combination with less dependence on GLP-1-mediated pharmacology, avoided the adverse gastrointestinal effects that typify selective GLP-1-based agonists. This discovery and validation of a balanced and high-potency dual incretin agonist enables a more physiological approach to management of diseases associated with impaired glucose tolerance.

Este trabalho analisa as interações mantidas entre a comunidade do Bairro Japuí, situado no município de São Vicente (SP),e o Parque Estadual Xixová-Japuí (PEXJ). Para tal, foram aplicados questionários semiestruturados a moradores do bairro e atores relacionadosao Parque, incluindo seu gestor à época, abordando aspectos sobre informação ambiental, interação com o território da UC,conhecimento e disponibilidade de informações sobre o Parque. Os resultados revelam um bairro de classe média baixa, cujos moradoresdetinham em geral baixo grau de instrução. O relacionamento da comunidade com a gestão do PEXJ era praticamente inexistente, o quepode ter sido consequência da não inserção da população nos assuntos dessa UC. Evidenciou-se também o baixo conhecimento e interessesobre o parque, por parte dos moradores, bem como o insucesso da administração, até aquele momento, em inserir a comunidade nadiscussão e gestão da unidade. Tal situação provocou uma relação conflituosa entre o PEXJ e membros da comunidade, levando a umcenário onde a gestão não era baseada em ações participativas.
This work analyzes the interactions between the community of Japuí Quarter, in the city of São Vicente (SP), and Xixová-Japuí (PEXJ) State Park. For doing this, a semi-structured questionnaire was applied to inhabitants of the quarter and actors related to the Park, including its manager at the time, approaching aspects on environmental information, interaction with the UC (Unit of Conservation) territory, knowledge and availability of information on the Park. The results showed a low middle class population with low degree of instruction in general. The relationship of the community with PEXJ management was almost nonexistent, something which may result from the fact the population are not considered by the UC. One also proved the low knowledge and interest on the Park by inhabitants, as well as the failure of the administration, until that moment, in inserting the community in the units discussion and management.Such situation allowed the establishment of a conflicting relationship between the PEXJ and members of the community, leading to a situation where management has not established participative actions.
Este trabajo analiza las interacciones entre la comunidad del barrio Japuí, en la ciudad de São Vicente (SP), y el parque estadual de Xixová-Japuí (PEXJ). Se utilizó un cuestionario semi-estructurado con los habitantes del barrio y los agentes relacionados conel parque, incluyendo su encargado en ese entonces, acercándose a aspectos de la información sobre el medio ambiente, la interacción con el territorio de esa UC (unidad de conservación), el conocimiento y a la disponibilidad de información sobre el parque. Los resultados demostraron una población de clase media baja con grado bajo de instrucción en general. La relación de la comunidad con la gerencia dePEXJ era casi no existente, algo que puede resultar del hecho que la UC no considera a la población. Uno también probó el bajo conocimiento y interés de los habitantes por el parque, así bien la falta de iniciativas de la administración, hasta ese momento, en la inserciónde la comunidad en la discusión de la unidad y de la gerencia. Tal situación permitió el establecimiento de una relación de conflicto entre el PEXJ y los miembros de la comunidad, llevando a una situación donde la gerencia no ha establecido acciones participativas.
