Uterine Artery Embolization Versus Hysterectomy in Postpartum Hemorrhage: A Systematic Review With Meta-Analysis.

PURPOSE: The objective of this study is to perform a meta-analysis comparing the effectiveness of uterine artery embolization (UAE) versus peripartum hysterectomy for acute refractory postpartum hemorrhage (PPH) control. MATERIALS AND METHODS: We systematically searched 6 medical databases for studies comparing UAE and hysterectomy in PPH. Outcomes examined were mortality, hospitalization duration (HD) in days, and red blood cells (RBC) units utilization. Statistical analysis used RevMan 5.1.7 and random-effects models. Odds ratios (OR) and mean differences (MDs) with 95% confidence intervals (CIs) were used for dichotomous and continuous outcomes, respectively. RESULTS: We included 833 patients from 4 cohort studies, with 583 (70%) undergoing UAE. The UAE population required fewer RBC units (MD: -7.39; 95% CI: -14.73 to -0.04; p=0.05) and had shorter HD (MD: -3.22; 95% CI: -5.42 to -1.02; p=0.004). Lower mortality rates were noted for UAE in the pooled analysis, but no statistical significance. Uterine artery embolization demonstrated lower procedural complications (16.45% vs. 28.8%), in which UAE had less ureter and bladder lesions (OR: 0.05; 95% CI: 0.01-0.38; p=0.004 and OR: 0.02; 95% CI: 0.00-0.15; p<0.001, respectively). Only 35 (6%) required conversion to hysterectomy, while 27 (4.6%) underwent re-embolization with 100% bleeding control. Uterine artery embolization did not hinder fertility, with normal menstruation restored in 19 patients with postoligomenorrhea. CONCLUSION: Uterine artery embolization for the control of PPH is associated with lower use of RBC units and HD, but similar rates of mortality are noted when compared to hysterectomy. These results associated with uterine preservation could support its importance for refractory PPH management. CLINICAL IMPACT: Uterine Artery Embolization is associated with a shorter hospitalization duration and reduced use of red blood cell units when compared with hysterectomy in refractory postpartum hemorrhage. Although demonstrating similar mortality rates, these findings, together with fertility preservation, support the method incorporation as a valuable option in obstetric services.

Antimicrobial and antibiofilm activity of highly soluble polypyrrole against methicillin-resistant Staphylococcus aureus.

AIMS: The purpose was to evaluate the antimicrobial activity of highly soluble polypyrrole (Hs-PPy), alone or combined with oxacillin, as well as its antibiofilm potential against methicillin-resistant Staphylococcus aureus strains. Furthermore, the in silico inhibitory mechanism in efflux pumps was also investigated. METHODS AND RESULTS: Ten clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA) and two reference strains were used. Antimicrobial activity was determined by broth microdilution, and the combination effect with oxacillin was evaluated by the checkerboard assay. The biofilm formation capacity of MRSA and the interference of Hs-PPy were evaluated. The inhibitory action of Hs-PPy on the efflux pump was evaluated in silico through molecular docking. Hs-PPy showed activity against the isolates, with inhibitory action between 62.5 and 125 µg ml-1 and bactericidal action at 62.5 µg ml-1, as well as synergism in association with oxacillin. The isolates ranged from moderate to strong biofilm producers, and Hs-PPy interfered with the formation of this structure, but not with mature biofilm. There was no in silico interaction with the efflux protein EmrD, the closest homolog to NorA. CONCLUSIONS: Hs-PPy interferes with biofilm formation by MRSA, has synergistic potential, and is an efflux pump inhibitor.

Pressure dynamics of the esophagogastric junction at rest and during inspiratory maneuvers after Nissen fundoplication.

Low sphincter pressure and inability of the crural diaphragm to elevate it at the esophagogastric junction are important pathophysiological mechanisms of gastroesophageal reflux disease (GERD). The object of this study was to depict how Nissen fundoplication changed the resting and inspiratory pressures of the anti-reflux barrier. We selected 14 patients (eight males; mean age 42.7 years; mean body mass index 27.8) for surgery. They answered symptoms questionnaires and underwent high-resolution manometry (HRM) before and 6 months after Nissen fundoplication. We used a standard manometric protocol (resting and liquid swallows) and assessment of esophagogastric junction (EGJ) pressure metrics during standardized forced inspiratory maneuvers against increasing loads (Threshold Maneuvers). We used the Wilcoxon test for comparison of pre and postoperative data. After fundoplication, heartburn and regurgitation scores diminished remarkably (from 4.5 and 2, respectively, to zero; P = 0.002 and P = 0.0005, respective medians). Also, the median expiratory EGJ pressure had a significant increase from 8.1 to 18.1 mmHg (P = 0.002), while mean respiratory pressure and EGJ contractility integral (EGJ-CI) increased without statistical significance (P = 0.064 and P = 0.06, respectively). Axial EGJ displacement was lower after fundoplication. The EGJ relaxation pressure (P = 0.001), the mean distal esophageal intrabolus pressure (P = 0.01) and the distal latency (P = 0.017) increased after fundoplication. There was a reduction in the contraction front velocity (P = 0.043). During evaluation with standardized inspiratory maneuvers, the inspiratory EGJ pressures (under loads of 12, 24, 36 and 48 cmH2O) were lower after surgery for all loads (median for load 12 cmH2O: 145.6 vs. 102.7 mmHg; P = 0.004). Fundoplication and hiatal closure increased the expiratory EGJ pressure and promoted a great GERD symptom relief. The surgery seemed to overcompensate a reduced EGJ mobility and inspiratory pressure.

Sediment source fingerprints of natural processes and anthropogenic pressures: A contribution to manage the Paraopeba River basin impacted by the B1 tailings dam collapse.

Understanding the origins of sediment transport in river systems is crucial for effective watershed management, especially after catastrophic events. This information is essential for the development of integrated strategies that guarantee water security in river basins. The present study aimed to investigate the rupture of the B1 tailings dam of the Córrego do Feijão mine, which drastically affected the Brumadinho region (Minas Gerais, Brazil). To address this issue, a confluence-based sediment fingerprinting approach was developed through the SedSAT model. Uncertainty was assessed through Monte Carlo simulations and Mean Absolute Error (MAE). Estimates of the overall average contributions of each tributary were quantified for each station and annually during the period 2019-2021. It was observed that the sampling point PT-09, closest to the dam breach, contributed to almost 80% of the Paraopeba River in 2019. Despite the dredging efforts, this percentage increased to 90% in 2020 due to the need to restore the highly degraded area. Additionally, the main tributaries contributing to sediment increase in the river are Manso River "TT-03" (almost 36%), associated with an area with a high percentage of urban land use, and Cedro stream "TT-07" (almost 71%), whose geology promotes erosion, leading to higher sediment concentration. Uncertainties arise from the limited number of available tracers, variations caused by dredging activities, and reduced data in 2020 due to the pandemic. Parameters such as land use, riparian vegetation degradation, downstream basin geology, and increased precipitation are key factors for successfully assessing tributary contributions to the Paraopeba River. The obtained results are promising for a preliminary analysis, allowing the quantification of key areas due to higher erosion and studying how this disaster affected the watershed. This information is crucial for improving decision-making, environmental governance, and the development of mitigating measures to ensure water security. This study is pioneering in evaluating this methodology in watersheds affected by environmental disasters, where restoration efforts are ongoing.

Is primary health care worth it in the long run? Evidence from Brazil.

This paper assesses whether Brazilian primary health care is worth it in the long-run by estimating the accumulated costs and benefits of its flagship, the Family Health Strategy program (ESF). We employ an alternative strategy centered on years of exposure to the program to incorporate its dynamics. We also account for the program's heterogeneity with respect to the remuneration of ESF health teams and the intensity of coverage across Brazilian municipalities, measure by the number of people assisted by each ESF team, on average. To address heterogeneity in professional earnings, this paper employs, for the first time, a dataset containing the remuneration of professionals allocated to all ESF teams nationwide. The benefits are measured by the avoided deaths and hospitalizations due to causes sensitive to primary care. Results suggest that the net monetary benefit of the program is positive on average, with an optimum time of exposure of approximately 16 years. Significant heterogeneities in cost-benefit results were found since costs outweigh benefits in localities where the coverage is low intensive. On the other hand, the benefits outweigh the costs by 22.5% on average in municipalities with high intensive coverage.

Controversies in immunotherapy for anti-NMDA receptor encephalitis: a scoping review with a proposal of operational definitions.

Anti-NMDA receptor encephalitis (NMDARE), an autoimmune encephalitis associated with autoantibodies against the N-methyl-D-aspartate (NMDA) receptor, affects predominantly young women and is associated with psychiatric symptoms, seizures, movement disorders, and autonomic instability. Traditional treatments of anti-NMDA receptor encephalitis involve corticosteroids, intravenous immunoglobulin, plasmapheresis, cyclophosphamide, and rituximab. However, many controversies remain in the treatment for NMDA receptor encephalitis, such as optimal timing and combination of different immunotherapies, the role of newer strategies (e.g., bortezomib or tocilizumab) for severe and refractory patients, and the need or not for long-term immunosuppression. Our goal was to perform a scoping review to discuss the controversial topics of immunotherapy for NMDA receptor encephalitis and propose operational definitions to guide clinical practice and future research in the field.

The Italian Unitary Society of Colon-proctology (SIUCP: Società Italiana Unitaria di Colonproctologia) guidelines for the management of anal fissure.

INTRODUCTION: The aim of these evidence-based guidelines is to present a consensus position from members of the Italian Unitary Society of Colon-Proctology (SIUCP: Società Italiana Unitaria di Colon-Proctologia) on the diagnosis and management of anal fissure, with the purpose to guide every physician in the choice of the best treatment option, according with the available literature. METHODS: A panel of experts was designed and charged by the Board of the SIUCP to develop key-questions on the main topics covering the management of anal fissure and to performe an accurate search on each topic in different databanks, in order to provide evidence-based answers to the questions and to summarize them in statements. All the clinical questions were discussed by the expert panel in different rounds through the Delphi approach and, for each statement, a consensus among the experts was reached. The questions were created according to the PICO criteria, and the statements developed adopting the GRADE methodology. CONCLUSIONS: In patients with acute anal fissure the medical therapy with dietary and behavioral norms is indicated. In the chronic phase of disease, the conservative treatment with topical 0.3% nifedipine plus 1.5% lidocaine or nitrates may represent the first-line therapy, eventually associated with ointments with film-forming, anti-inflammatory and healing properties such as Propionibacterium extract gel. In case of first-line treatment failure, the surgical strategy (internal sphincterotomy or fissurectomy with flap), may be guided by the clinical findings, eventually supported by endoanal ultrasound and anal manometry.

Methodological quality of evidence-based clinical practice guidelines in cariology.

OBJECTIVE: The present study aimed to appraise the methodological quality of evidence-based Clinical Practice Guidelines (CPGs) in the cariology field. MATERIALS AND METHODS: A systematic search on electronic databases (MEDLINE/Pubmed, EMBASE, DARE and Epistemonikos), websites, and guideline organizations were undertaken. Evidence-based CPGs including at least one recommendation for clinical prevention and/or management of dental caries, developed for any clinical setting, were included. The quality of each guideline was evaluated using the AGREE II tool. Descriptive analysis was performed and the average overall score for each domain was calculated. RESULTS: Thirty-two guidelines were included. Most of the CPGs achieved higher scores for the domains of clarity of presentation (66.7%, 95% IC 37.3-52.2) and scope and purpose (59.6%, 95% IC 53.7-65.5) domains; and lower scores for editorial independence (46.1%, 95% IC 37.8-55.7) and applicability domain (44.7%, 95% IC 37-55.3). The reviewers assessed 12 CPGs (37.5%) as recommended for use, 15 (46.9%) recommended with modifications, and 5 (15.6%) as not recommended. CONCLUSION: The overall methodological quality of evidence-based CPGs in the cariology field is moderate, and there is a need for improvements in reporting related to most domains. The poorest reporting was found in the description of the domains' applicability of its recommendations and editorial independence. CLINICAL RELEVANCE: Clinical Practice Guidelines provide guidance to patients, healthcare professionals, and stakeholders. The quality of these documents is essential for establishing trust in their recommendations.

[Community participation in health as an essential element for health system strengthening in the AmericasLa participación en salud como elemento indispensable para el fortalecimiento de los sistemas de atención de salud en las Américas]. / Participação em saúde como elemento indissociável para o fortalecimento dos sistemas de atenção à saúde nas Américas.

The present narrative review discusses the relevance and challenges of community participation in health for health system strengthening. Based on a definition of community participation in health as a dynamic process that gives people access and control over health resources through involvement and experience, the article summarizes information obtained from documents and debate at an international event (Seminario Internacional: Experiencias y Modelos de Participación en Salud en América Latina y el Caribe). In addition, the SciELO, PubMed and Google Scholar databases were searched using the terms "community participation", "community engagement", "social control" and "community health planning" to identify national or transnational review and opinion articles. Community participation in health is a current concept, acknowledged in the recommendations for health policies described in recent documents and publications. Around the world, the number of studies on the subject is growing; however, in the Americas, three countries (United States, Canada and Brazil) accounted for most of the scientific publications identified in the databases. The studies address timely questions and show consensus among investigators within each individual research group. However, the area lacks exchanges and comparative analyses that contrast different experiences transcending national borders and expanding knowledge on community participation in health. The creation of more spaces for the sharing of experiences and research is advised, as well as the establishment of professional and research networks in the field of community participation in health.

En esta revisión narrativa se analizan la relevancia y los retos de la participación en salud para el fortalecimiento de los sistemas de atención de salud. A partir de una definición de la participación en salud como un proceso dinámico que da a las personas acceso y control sobre los recursos de salud por medio de la intervención y la experiencia, en el artículo se sintetiza la información obtenida de documentos y en un debate realizado en el denominado Seminario Internacional: Experiencias y Modelos de Participación en Salud en América Latina y el Caribe. A este material se agregaron los resultados de búsquedas en las bases de datos SciELO, PubMed y Google Académico con los términos "community participation", "community engagement", "social control" y "community health planning". Se seleccionaron artículos de revisión y opinión de los ámbitos nacional o transnacional, sin límite de fecha ni de idioma. La participación en salud es un concepto actual, legitimado en las recomendaciones sobre políticas de salud descritas en documentos y publicaciones recientes. El número de estudios sobre el tema ha aumentado en todo el mundo, pero en las Américas, la mayoría de las publicaciones se concentran en tres países (Brasil, Canadá y Estados Unidos). En los estudios se abordan asuntos de actualidad y se demuestra el consenso existente entre los investigadores de cada grupo independiente. Sin embargo, en este campo no hay intercambios ni análisis comparativos que permitan contrastar las diferentes experiencias más allá de las fronteras nacionales y ampliar el conocimiento sobre la participación en salud. Se recomienda crear ámbitos de intercambio de experiencias y oportunidades de investigación, y establecer redes profesionales y de investigación en el campo de la participación en salud.

[Strengthening regional governance and the health care network in small municipalities in BrazilFortalecimiento de la gobernanza regional y de la red de atención de salud en municipios pequeños de Brasil]. / Fortalecimento da governança regional e da rede de atenção à saúde em municípios pequenos no Brasil.

In Brazil, 67.7% of the municipalities are characterized as small, with a population of less than 20 thousand. The objective of this article is to systematize the experience and identify the challenges and lessons learned in the implementation of the model for strengthening regional governance and organizing the health care network (HCN) in a region of Brazil composed of these municipalities, which present low technical and budgetary capacity, in addition to various fragilities related to the organization of the HCN. With a view to strengthening regional governance and the organization of the primary health care (PHC) work process and, consequently, the workflow with other levels of care, a strategy entitled More Care More Health (Mais Cuidado Mais Saúde) was proposed, developed in partnership with the Pan American Health Organization/World Health Organization (PAHO/WHO) and the Ministry of Health. The project was developed through permanent health education and institutional capacity building in the region of Ivaiporã, state of Paraná, based on workshops and addressing three priority axes: HCN integration, capacity building and information management. The target audience were the extended PHC teams. The project made it possible to develop local and governance capacities through joint reflections on the health care model, its components and the necessary changes in work processes for health promotion with a focus on the quality of life of users. Because it is an experience that considers the weaknesses, needs and autonomy of local actors, the project has a high potential for replication and customization for other regions with similar characteristics inside and outside Brazil.

En Brasil, 67,7% de los municipios se clasifican como pequeños, puesto que tienen menos de 20 000 habitantes. El objetivo de este artículo es sistematizar la experiencia adquirida y determinar cuáles son los desafíos y las enseñanzas extraídas en la implementación del modelo de fortalecimiento de la gobernanza regional y de la organización de la red de atención de salud en una región de Brasil compuesta por municipios de este tipo, que tienen poca capacidad técnica y presupuestaria y diversas debilidades relacionadas con la organización de dicha red. Desde la perspectiva del fortalecimiento de la gobernanza regional y de la organización del proceso de trabajo en el campo de la atención primaria de salud y, por consiguiente, de los flujos asistenciales con los demás niveles de atención, se propuso la estrategia Más cuidado, más salud, formulada junto con la Organización Panamericana de la Salud/Organización Mundial de la Salud (OPS/OMS) y el Ministerio de Salud. El proyecto se ejecutó por medio de procesos de educación permanente en salud y fortalecimiento de las capacidades institucionales en la región de Ivaiporã, Estado de Paraná, con talleres descentralizados, dentro de tres ejes prioritarios, a saber, integración de red de atención de salud, capacitación y gestión de la información. El público destinatario fueron los equipos de atención primaria de salud ampliada. El proyecto permitió el desarrollo de las capacidades locales y la gobernanza regional por medio de reflexiones conjuntas sobre el modelo de atención de salud, sus elementos constitutivos y los cambios necesarios en los procesos de trabajo para impulsar la promoción de la salud centrada en la calidad de vida de los usuarios. Por tratarse de una experiencia en la cual se tienen en cuenta las debilidades, las necesidades y la autonomía de los actores locales, el proyecto tiene un alto poder de repetición y adaptación en otras regiones con características similares dentro y fuera de Brasil.

Biofortification of Kidney Bean (Phaseolus vulgaris L.) Crops Applying Zinc Sulfate and Ferric Sulfate: Pilot Crop in Colombia.

Agriculture is one of the economic activities with the most potential in Colombia, given its climatic and geographical conditions. Bean cultivation is classified as climbing, which grows in a branched way, and bushy, whose growth occurs up to 70 cm. The objective of this research was to study zinc and iron sulfates in different concentrations as fertilizers capable of increasing the nutritional value of kidney beans (Phaseolus vulgaris L.), whose strategy is known as biofortification, and thus determine the most effective sulfate. The methodology details the sulfate formulations, their preparation, the application of additives, sampling and quantification methods of total iron, total zinc, °Brix, carotenoids, chlorophylls a, b, and antioxidant capacity using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method in leaves and pods. As for the results, it was found that biofortification with iron sulfate and zinc sulfate is a strategy that favors the country's economy and human health, because it allows the increase of minerals, antioxidant capacity and total soluble solids.

Management of traumatic superficial palmar arch pseudoaneurysm: a therapeutic challenge.

Pseudoaneurysm of the palmar arch is a rare entity. Diagnosis is dependent on high clinical suspicion. We present a case referred to the emergency department, with a history of glass penetrating trauma to the palmar surface with a pulsatile mass and jet bleeding. Doppler ultrasound evidenced a partially thrombosed pseudoaneurysm. A CT angiography examination showed a saccular formation arising from the superficial palmar arch. A conventional surgical approach was indicated. A clinical suspicion must be ventured to arrive at the correct diagnosis. Imaging modalities are needed to identify the pseudoaneurysm and plan the treatment course. Nonetheless, the sequence of diagnosis is individual, because further evaluation with different imaging methods may not change the rationale for the intervention. In our experience, conventional surgical removal is preferable, due to its safety and well-established outcomes.

O pseudoaneurisma do arco palmar é uma entidade rara, cujo diagnóstico depende de alta suspeição clínica. Apresentamos o caso de um paciente encaminhado ao pronto-socorro com história de traumatismo penetrante por vidro na face palmar, com massa pulsátil e sangramento em jato. A ultrassonografia com Doppler evidenciou pseudoaneurisma parcialmente trombosado, e a angiotomografia demonstrou formação sacular originada do arco palmar superficial. Uma abordagem cirúrgica convencional foi indicada. Para prosseguir com o diagnóstico correto, essa suspeita clínica deve ser aventada. Modalidades de imagem são necessárias para identificar o pseudoaneurisma e planejar o curso do tratamento. No entanto, a sequência diagnóstica é individual, pois uma avaliação mais aprofundada, com diferentes métodos de imagem, pode não alterar o racional da intervenção. Em nossa experiência, a remoção cirúrgica convencional é preferível, visto sua segurança e seus resultados bem estabelecidos.

Extracorporeal membrane oxygenation outcomes in COVID-19 patients: Case series from the Brazilian COVID-19 Registry.

Around 5% of coronavirus disease 2019 (COVID-19) patients develop critical disease, with severe pneumonia and acute respiratory distress syndrome (ARDS). In these cases, extracorporeal membrane oxygenation (ECMO) may be considered when conventional therapy fails. This study aimed to describe the clinical characteristics and in-hospital outcomes of COVID-19 patients with ARDS refractory to lung-protective ventilation and prone positioning on ECMO support, as well as to review the available literature on ECMO use and COVID-19 patients' outcome. Patients from this case series were selected from the Brazilian COVID-19 Registry. From the 7646 patients included in the registry, only eight received ECMO support (0.1%), in four hospitals. The median age of the entire sample was 59 (interquartile range 54.2-64.4) years old and 87.5% were male. Hypertension (50.0%), diabetes mellitus (50.0%) and obesity (37.5%) were the most frequent comorbidities. The indications for ECMO were PaO2 /FiO2 ratio <80 mm Hg for more than 6 h or PaO2 /FiO2 ratio <60 mm Hg for more than 3 h. The mortality rate was 87.5%. In conclusion, in this case series of COVID-19 patients with ARDS refractory to conventional therapy who received ECMO support, a very high mortality was observed. Our findings are not different from previous studies including a small number of patients; however, there is a huge difference from Extracorporeal Life Support Organization results, which encourages us to keep looking for improvement.

Beyond empathy decline: Do the barriers to compassion change across medical training?

BACKGROUND: Despite being a mandated, foundational value in healthcare, research on compassion remains limited. Studying the individual, patient, clinical, and contextual factors that interfere with compassion-the "barriers"-may clarify our understanding of the origins of compassion and identify potential targets for improving patient-centred care. Studies of the related construct of empathy have suggested that medical students report declines with increasing clinical experience. In contrast, when comparing physicians with medical students, increased clinical experience predicts lower barriers to compassion. Whether-and how-a similar experience-related decline in the factors that interfere with compassion occurs across medical training remains unknown. AIMS: To describe how the barriers to compassion vary across clinical training in medical students. METHOD: New Zealand medical students (N = 351) in their clinical years (Years 4-6) completed measures of the Barriers to Physician Compassion (BPCQ) and potential covariates such as demographics, work burden factors, and dispositional factors. The BPCQ indexes the extent to which barriers in four domains (individual, patient, clinical, and contextual) interfere with a physician/student's compassion towards patients. Analyses of variance and regression analyses were used to explore the effect of year level on the four types of barriers. RESULTS: Year 4 students reported slightly lower student-related, environmental and patient/family-related (but not clinical) barriers than Year 6 students (effect size: É·2 < 0.05); all barriers increased comparably across training. Controlling for relevant confounds, regression analyses confirmed that lower year level predicted lower barriers to compassion. Higher self-compassion, but not gender, predicted lower barriers. CONCLUSIONS: In extending studies of empathy decline, this report suggests that students experience higher barriers to compassion as clinical training progresses. This is in contrast to existing studies contrasting physicians with medical students, where greater experience was associated with lower perceived barriers to compassion. Self-compassion may offset increases in barriers to care.

Patterns in Academic Cosmetic Surgery Practice: Population Differences and Procedure Preferences.

PURPOSE: Although growth in cosmetic surgery remains constant in the private setting, academic cosmetic surgery practices are often underdeveloped. Our study aims to determine which patient populations access academic cosmetic surgery services. METHODS: The 2018 Health Care Utilization Project Nationwide Ambulatory Surgery Sample database was used for data analysis. Encounters for the following American Society of Plastic Surgery top 5 procedures for 2020 were selected: blepharoplasty, breast augmentation, liposuction, rhinoplasty, and rhytidectomy. Patient encounter data were collected because it relates to median income, geographic location, and primary payer status. RESULTS: The 2018 Nationwide Ambulatory Surgery Sample data set contained 44,078 encounters at academic surgical centers for the procedures listed previously. Low-income patients account for 13.7% of academic cosmetic surgery encounters compared with 37.9% for high-income patients. Breast augmentation rates are higher among low-income patients (20.5% vs 17.2%, P < 0.001), and high-income patients undergo rhytidectomy more frequently (5.7% vs 3.0%, P < 0.001). In the academic setting, patients from large metropolitan areas encompass the majority of cosmetic encounters (71.0%), and these patients are more likely to proceed with rhinoplasty, rhytidectomy, and liposuction procedures (P < 0.001). Patients from smaller metropolitan areas undergo blepharoplasty more frequently compared with those from larger metropolitan areas (56.4% vs 41.8%, P < 0.001). Self-pay and privately insured patients comprise the majority of academic cosmetic surgery encounters (40.8% and 29.9%, respectively). Eighty-eight percent of Medicare patients within this cohort underwent blepharoplasty, whereas self-pay patients accessed breast augmentation, liposuction, and rhytidectomy more often than other insured patients. CONCLUSIONS: Income status, patient location, and primary payer status play an important role in academic cosmetic surgery access rates and procedure preferences. Academic cosmetic practices can use these insights to tailor their services to the populations they serve.

Temporal trends and spatial clusters of gastric cancer mortality in Brazil.

Objective: To identify nationwide temporal trends and spatial patterns of gastric cancer-related mortality in Brazil. Methods: An ecological study was performed using death certificates registered from 2000 to 2019 in which gastric cancer was recorded as any cause of death (an underlying or associated cause). Trends over time were assessed using joinpoint regression models. Spatial and spatiotemporal clusters were identified by Kulldorff's space-time scan statistics to identify high-risk areas. Results: In 276 897/22 663 091 (1.22%) death certificates gastric cancer was recorded as any cause of death. Age-adjusted gastric cancer-related mortality increased significantly over time (annual percentage change [APC]: 0.7, 95% confidence interval [CI]: 0.5 to 0.8). The increase in mortality was more pronounced in the less-developed North and Northeast Regions (North Region, APC: 3.1, 95% CI: 2.7 to 3.5; Northeast Region, APC: 3.1, 95% CI: 2.5 to 3.7). Eight spatiotemporally associated high-risk clusters of gastric cancer-related mortality were identified in the North, South, Northeast and Central-West Regions, as well as a major cluster covering a wide geographical range in the South and Southeast Regions of Brazil during the first years of the study period (2000 to 2009). Conclusions: More recently, during 2010 to 2019, clusters of gastric cancer have been identified in the Northeast Region. The nationwide increase in mortality in this analysis of 20 years of data highlights the persistently high burden of gastric cancer in Brazil, especially in socioeconomically disadvantaged regions. The identification of these areas where the population is at high risk for gastric cancer-related mortality emphasizes the need to develop effective and intersectoral control measures.

Brewing by-product valorisation: trub debittered for nutritional and quality improvement of pasta.

Trub, a brewing by-product, can be used as alternative ingredient for foods nutritional enrichment after its bitter compounds extraction. Study presents the optimisation of bitter compounds extraction from trub by Box-Behnken design, and use of debittered trub (DT) as new ingredient to enrich pasta. Bitterness extraction process was evaluated at different pH levels, time and extraction steps, and physical-chemical properties of DT (obtained under optimal conditions) were evaluated. Pasta was enriched with DT (5%, 10% and 15%) and its physical-chemical and quality properties were evaluated. Protein structure and chemical composition of trub were altered after process, also modifying its technological properties. Pasta with 10% DT increased in 33.51% protein content. Interaction of DT and wheat proteins resulted in a more compact structure, and DT water absorption capacity provided pasta texture changes. DT use improved pasta nutritional and quality properties, enabling trub valorisation and its use as vegetable proteins alternative source.

Assessment of high spatial resolution satellite imagery for monitoring riparian vegetation: riverine management in the smallholding.

Riverine habitats are essential ecotones that bridge aquatic and terrestrial ecosystems, providing multiple ecosystem services. This study analyses the potential use of high-resolution satellite imagery, provided by the WorldView-2 satellite, in order to assess its viability for monitoring riparian ecosystems. It is performed by calculating the riparian strip quality index (RSQI) and calibrating it with the riparian quality index (QBR). The methodology was implemented in the Umia River, which is characterised by elevated anthropogenic pressures (located in the northwest of Spain). The results obtained by the method have a 92% of veracity and a kappa coefficient of 0.88. The average quality value obtained for the RSQI index was 71.57, while the average value for the QBR was 55.88. This difference could be attributed to the fact that the former does not differ between autochthonous and non-autochthonous vegetation. The areas with more accurate mapping corresponded to stretches of vegetation with optimal cover (80-50%), with good connectivity with the adjacent forest ecosystem and few or no presence of invasive plants. The worst-scoring sites had the next characteristics: low connectivity (< 10%), low forest cover (< 10%) and a higher presence of invasive plants. The degradation of vegetation could be explained by the presence of agriculture and deficient land use rationing caused by the type of ownership of the study area. The application of this index through satellite images will facilitate the environmental governance of multiple ecosystems and in special riparian ecosystems, obtaining a quick and objective methodology, easily replicable in other basins.

Skin field cancerisation: A systematic review of the literature regarding its treatment.

INTRODUCTION: Skin neoplasms are the most frequent malignant lesions, increasing patient's morbidity when associated with skin field cancerisation. There is a need to understand the current therapies, both clinical and surgical. METHODS: A systematic review was performed according to the PRISMA guideline, registered in PROSPERO: CRD42018114826, including studies from 2012 to 2019. RESULTS: Seven hundred and eighty-two studies were found, of which 21 were included. Of these, 8 primary studies were randomised controlled trials: fractional CO2 laser-assisted photodynamic therapy (PDT) vs. PDT (no significance), daylight PDT vs. PDT (no significance, daylight PDT had less adverse effects), trichloroacetic acid peel vs. 5-aminolaevulinic acid PDT (clinical improvement of aminolaevulinic acid PDT), 5-Fluorouracil 0.5%/Salicylic Acid 10% vs. vehicle (clinical improvement of 5-Fluorouracil 0.5%/Salicylic Acid 10%), photolyase vs. sun filters (no significance), sunscreens vs. sunscreens plus DNA repair enzymes (DNA Repair Enzymes was more effective in reducing field cancerisation). Only one systematic review was included in which there was effectiveness of daylight PDT in the treatment of actinic keratoses. The other 12 included studies had a lower level of evidence including surgical studies. CONCLUSION: Clinical studies are more relevant in the treatment of the field cancerisation.

Primary care coverage and individual health: evidence from a likelihood model using biomarkers in Brazil.

BACKGROUND: Although the use of biomarkers to assess health outcomes has recently gained momentum, literature is still scarce for low- to middle-income countries. This paper explores the relationship between primary care coverage and individual health in Brazil using a dataset of blood-based biomarkers collected by the Brazilian National Health Survey. Both survey data and laboratory results were crossed with coverage data from the Family Health Strategy (ESF) program, the most important primary care program in Brazil; the coverage measures aim to capture both direct (household) and indirect (spill-over) effects. METHODS: The empirical strategy used a probit model to estimate the relationship between ESF program coverage and the likelihood of abnormal biomarker levels while controlling for a rich set of individual and household characteristics based on data from the national survey. RESULTS: Household ESF coverage was associated with a lower likelihood of abnormal results for biomarkers related to anemia (marginal effect between - 2.16 and - 2.18 percentage points), kidney failure (between - 1.01 and - 1.19 p.p.), and arterial hypertension (between - 1.48 and - 1.64 p.p). The likelihood of abnormal levels of white blood cells and thrombocytes was negatively related to primary care coverage (marginal effect between - 1.8 and - 2 p.p.). The spillover effects were relevant for kidney failure and arterial hypertension, depending on the regional level. Although not sensitive to household coverage, diabetes mellitus was negatively associated with the state supply of primary care, and abnormal cholesterol levels did not present any relationship with ESF program coverage. CONCLUSIONS: The presence of spillover effects of ESF program coverage regarding these conditions reveals that the strengthening of primary care by increasing the household registration and the regional density of ESF teams is an efficient strategy to address important comorbidities.
