Impact of Targeted Therapy on the Survival of Patients With Advanced-Stage Non-small Cell Lung Cancer in Oncosalud - AUNA.

BACKGROUND: Lung cancer is still a prevalent and fatal neoplasm in developing countries. In the last decades, chemotherapy (CHT) maintenance occupied an important role in the treatment, as well as targeted therapies. We aimed to evaluate the survival impact of targeted therapy in advanced lung cancer at a private Peruvian institution (Oncosalud - AUNA). METHODS: We reviewed retrospectively medical records of patients with advanced-stage non-small cell lung cancer (NSCLS) (clinical stage III-IV) who received CHT and maintenance treatment with target therapy (TT) or CHT. The impact was assessed by progression-free survival (PFS) and overall survival (OS) using the Kaplan-Meier method, and comparisons of survival curves were performed using log-rank or Breslow test and Cox model. RESULTS: The median age of the patients was 65 years. Clinical characteristics, as well as the treatment type, showed no significant difference between the two groups. The maintenance schedule in those receiving CHT was generally pemetrexed (70%) and in those receiving TT was erlotinib (60.7%). In patients receiving TT, the median PFS was 13 months compared to 7 months in those receiving CHT; likewise, the median OS was 45 and 17 months, respectively. The PFS and OS curves showed significant differences (P < .05), achieving a better survival in subjects treated with TT. CONCLUSION: Progression-Free Survival and OS were superior in patients who received targeted therapy than those treated only with CHT, the 2 years rate of PFS and OS was nearly double to those who received only CHT-based treatments.

Plants Used in Mexican Traditional Medicine for the Management of Urolithiasis: A Review of Preclinical Evidence, Bioactive Compounds, and Molecular Mechanisms.

Urolithiasis (UL) involves the formation of stones in different parts of the urinary tract. UL is a health problem, and its prevalence has increased considerably in developing countries. Several regions use plants in traditional medicine as an alternative in the treatment or prevention of UL. Mexico has known about the role of traditional medicine in the management of urinary stones. Mexican traditional medicine uses plants such as Argemone mexicana L., Berberis trifoliata Hartw. ex Lindl., Costus mexicanus Liebm, Chenopodium album L., Ammi visnaga (L.) Lam., Eysenhardtia polystachya (Ortega) Sarg., Selaginella lepidophylla (Hook. & Grev.) Spring, and Taraxacum officinale L. These plants contain different bioactive compounds, including polyphenols, flavonoids, phytosterols, saponins, furanochromones, alkaloids, and terpenoids, which could be effective in preventing the process of stone formation. Evidence suggests that their beneficial effects might be associated with litholytic, antispasmodic, and diuretic activities, as well as an inhibitory effect on crystallization, nucleation, and aggregation of crystals. The molecular mechanisms involving these effects could be related to antioxidant, anti-inflammatory, and antimicrobial properties. Thus, the review aims to summarize the preclinical evidence, bioactive compounds, and molecular mechanisms of the plants used in Mexican traditional medicine for the management of UL.

PUM1 and RNase P genes as potential cell-free DNA markers in breast cancer.

BACKGROUND: Cell-free DNA (cfDNA) is used in clinical research to identify biomarkers for diagnosis of and follow-up on cancer. Here, we propose a fast and innovative approach using traditional housekeeping genes as cfDNA targets in a copy number analysis. We focus on the application of highly sensitive technology such as digital PCR (dPCR) to differentiate breast cancer (BC) patients and controls by quantifying regions of PUM1 and RPPH1 (RNase P) in plasma samples. METHODS: We conducted a case-control study with 82 BC patients and 82 healthy women. cfDNA was isolated from plasma using magnetic beads and quantified by spectrophotometry to estimate total cfDNA. Then, both PUM1 and RPPH1 genes were specifically quantified by dPCR. Data analysis was calibrated using a reference genomic DNA in different concentrations. RESULTS: We found RNase P and PUM1 values were correlated in the patient group (intraclass correlation coefficient [ICC] = 0.842), but they did not have any correlation in healthy women (ICC = 0.519). In dPCR quantification, PUM1 showed the capacity to distinguish early-stage patients and controls with good specificity (98.67%) and sensitivity (100%). Conversely, RNase P had lower cfDNA levels in triple-negative BC patients than luminal subtypes (p < 0.025 for both), confirming their utility for patient classification. CONCLUSION: We propose the PUM1 gene as a cfDNA marker for early diagnosis of BC and RNase P as a cfDNA marker related to hormonal status and subtype classification in BC. Further studies with larger sample sizes are warranted.

Breast cancer mortality trends in Peruvian women.

BACKGROUND: Breast cancer (BC) is the most common malignancy in Latin American women, but with a wide variability with respect to their mortality. This study aims to estimate the mortality rates from BC in Peruvian women and to assess mortality trends over 15 years. METHODS: We calculated BC age-standardized mortality rate (ASMR) per 100,000 women-years using the world standard SEGI population. We estimated joinpoint regression models for BC in Peru and its geographical areas. The spatial analysis was performed using the Moran's I statistic. RESULTS: In a 15-year period, Peru had a mortality rate of 9.97 per 100,000 women-years. The coastal region had the highest mortality rate (12.15 per 100,000 women-years), followed by the highlands region (4.71 per 100,000 women-years). In 2003, the highest ASMR for BC were in the provinces of Lima, Arequipa, and La Libertad (above 8.0 per 100,000 women-years), whereas in 2017, the highest ASMR were in Tumbes, Callao, and Moquegua (above 13.0 per women-years). The mortality trend for BC has been declining in the coastal region since 2005 (APC = - 1.35, p < 0.05), whereas the highlands region experienced an upward trend throughout the study period (APC = 4.26, p < 0.05). The rainforest region had a stable trend. Spatial analysis showed a Local Indicator of Spatial Association of 0.26 (p < 0.05). CONCLUSION: We found regional differences in the mortality trends over 15 years. Although the coastal region experienced a downward trend, the highlands had an upward mortality trend in the entire study period. It is necessary to implement tailored public health interventions to reduce BC mortality in Peru.

Socioeconomic disparities and the genomic landscape of gastric cancer.

The genomic characteristics of Peruvian patients with gastric adenocarcinoma from diverse socioeconomic backgrounds were examined in consideration of the possibility that patients from different socioeconomic backgrounds may be exposed to different risk factors. We conducted a prospective pilot study in two Peruvian cities (Lima and Ica). This study enrolled 15 patients from low socioeconomic status (LSES) and 15 patients from medium/high socioeconomic status (MHSES). The genomic profiling of gastric adenocarcinoma samples was done through the FoundationOne CDx platform. We compared the genomic characteristics and the need for targeted therapy and immunotherapy between LSES and MHSES. The genes with higher rates of alterations were TP53 (73.3% vs. 50.0%, P = 0.2635); CDH1 (26.7% vs. 28.6%, P = 1); CDKN2A (20.0% vs. 28.6%, P = 1); KRAS (33.3% vs. 7.1%, P = 0.1686); ARID1A (20.0% vs. 14.3%, P = 1); MLL2 (13.3% vs. 21.4%, P = 1) and SOX9 (33.3% vs. 0.0%, P = 0.0421) in LSES versus HMSES, respectively. There was no significant difference in tumor mutational burden (P = 0.377) or microsatellite status (P = 1). The LSES group had a higher need for targeted therapy or immunotherapy according to gene involvement and alterations. A significant genomic difference exists among patients with gastric adenocarcinoma of different socioeconomic status, which may result in a different need for targeted therapy and immunotherapy.

Gastric adenocarcinoma with high­level microsatellite instability: A case report.

Gastric cancer (GC) ranks fifth on the list of the most common malignancies worldwide. In Peru, gastric neoplasms are considered the second leading cause of mortality among males. Among the molecular subgroups of GC, microsatellite instability presents a favorable prognosis due to its hypermutated phenotype, which activates immunosurveillance. The present study describes the case of a 75-year-old patient, who was admitted in the hospital with a history of upper gastrointestinal bleeding and recurrent hospital admission, due to severe anemia. The patient presented with pale skin, normal vital functions, slight swelling of the lower extremities, and abdominal distention and bloating upon a physical examination. An endoscopic examination revealed an infiltrating circular ulcerated lesion. The histopathological analysis identified a moderately differentiated intestinal-type adenocarcinoma with pathological stage T3N0M0. Tumor genomic profiling demonstrated alterations in 15 different genes with a tumor mutational burden of 28 mutations/Mb. Finally, the patient underwent a partial gastrectomy without pre-operative chemotherapy. After 4 days, the patient presented with post-operative complications for which he was re-operated on. The patient did not survive. To the best of our knowledge, in the present case, pernicious anemia was an early sign of GC and a gastroscopy had to be performed. Furthermore, MutS homolog 3 alterations probably conditioned the presence of multiple frame-shift mutations.

Impact of surgical resection on the survival in Mexican patients with gastric cancer: A meta-analysis and systematic review.

BACKGROUND: Gastric cancer (GC) is one of the most frequent cancer types in Mexico. The primary method used as a treatment is surgical resection. The role of surgery in increasing survival is controversial. This study aimed to determine whether surgical resection increases the survival of patients with GC in a Mexican population. METHODS: A systematic review of literature searches (Evidence-based MEDLINE/PubMed, Web of Science, Cochrane Library, and SciELO) and meta-analysis were performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis criteria. The published articles from 2000 to the current time were divided into cross-sectional and randomized studies. The inclusion criteria were survival, surgical resections, patients treated in Mexico, and primary GC. The effect estimation was calculated using the risk ratio (RR). The random-effects model and a confidence interval (CI) of 95% were used. RESULTS: The RR of the pooled studies was 1.09 (95% CI, 0.71-1.67). RR of 0.82 (95% CI, 0.63-1.07) was obtained in cross-sectional studies, and randomized studies showed a RR of 2.08 (95% CI, 0.25-17.07). CONCLUSION: This work is the first systematic study that assesses the role of surgery on the survival of patients with GC in the Mexican population, the results showed that surgical resection did not improve survival in patients with GC.

Chip-based digital Polymerase Chain Reaction as quantitative technique for the detection of PIK3CA mutations in breast cancer patients.

Background: PIK3CA is a gene frequently mutated in breast cancer. With the FDA approval of alpelisib, the evaluation of PIK3CA for activating mutations is becoming routinely. Novel platforms for gene analysis as digital PCR (dPCR) are emerging as a potential replacement for the traditional Sanger sequencing. However, there are still few studies on chip-based dPCR to detect mutations in tumor samples. Thus, this cross-sectional study aimed to assess the sensibility of a chip-based dPCR to detect and quantify PIK3CA mutations and compare its performance with Sanger sequencing. Materials and Methods: Tumor samples from 57 breast cancer patients (22 pre-treatment samples, 32 tumors after neoadjuvant chemotherapy, and three lymph nodes) were collected and analyzed by Sanger sequencing and dPCR for the three PIK3CA most relevant mutations (p.E545K, p. H1047R, and p. H1047L). Digital PCR sensitivity, specificity, and overall performance were estimated by contingency tables, receptor operator characteristic (ROC), and area under the curve (AUC). Association of PIK3CA mutations with clinicopathological variables was conducted. Results: Sanger sequencing identified PIK3CA mutations in six patients (10.5%), two with p. H1047R, and four with p. E545K. Digital PCR confirmed those mutations and identified 19 additional patients with at least one mutation. Comparison between dPCR and Sanger sequencing showed a sensitivity of 100% (95% CI 53-100%), and a specificity of 84.2% (95% CI 83-84.2%). Besides, p. H1047R mutation detected by dPCR showed a significant association with breast cancer phenotype (p = 0.019) and lymphatic nodes infiltration (p = 0.046). Conclusions: Digital PCR showed a high sensitivity to detect mutations in tumor samples and it might be capable to detect low-rate mutations and tumor subpopulations not detected by Sanger sequencing.

Oxidative Stress Biomarkers and Their Association with Mortality among Patients Infected with SARS-CoV-2 in Mexico.

Background: Activation of the immune system response is associated with the generation of oxidative stress (OS). Several alterations are involved in OS, such as excessive production of reactive oxygen species (ROS) and decreased antioxidant activity, which together lead to an imbalance in redox status. The role of OS during SARS-CoV-2 infection is not fully understood. The aim of this study was to determine OS biomarkers and assess their usefulness as a predictor of mortality in COVID-19 patients. Methods: Baseline characteristics and serum samples were collected from hospitalized COVID-19 patients and compared with healthy controls. The serum OS biomarkers, including malondialdehyde (MDA) and total antioxidant capacity (TAC), were assessed by spectrophotometric and oxygen radical absorbance capacity (ORAC) methods, respectively. Results: A total of 152 individuals were analyzed (COVID-19 patients vs. healthy controls). Compared with healthy controls (n = 76), patients infected with SARS-CoV-2 (n = 76) presented higher levels of MDA (p < 0.001) and decreased TAC (p < 0.001). A total of 37 (49%) patients with COVID-19 died. The area under the receiver operating characteristic (ROC) curve (AUC) estimated that the combination of the OS biomarkers (MDA+TAC) (AUC = 0.6394, p = 0.037) was a significant predictor of mortality. A higher level of MDA was associated with mortality (HR, 1.05, 95% CI, 1.00-1.10, p = 0.045). Conclusion: This study concludes that OS is increased in patients with COVID-19 and is associated with mortality. To our knowledge, this is the first evidence of the expression of OS biomarkers and their association with mortality among the Mexican population.

Relationship between lipid accumulation product and oxidative biomarkers by gender in adults from Yucatan, Mexico.

Excessive adipose tissue can lead to metabolic abnormalities resulting in lipid alteration and oxidative stress (OS) status. The lipid accumulation product (LAP) index is a biomarker that indicates central lipid accumulation and has been proposed as an accurate and independent indicator of risk for several cardiometabolic related conditions. There is a lack of information about the possible association of LAP and OS biomarkers. Therefore, this work aimed to investigate the relationship between LAP and OS biomarkers in adults. A cross-sectional study was performed in 250 subjects attending the Hospital Regional de Alta Especialidad de la Península de Yucatán. Anthropometrical and clinical parameters were measured. The serum oxidative biomarkers such as malondialdehyde (MDA) and total antioxidant capacity (TAC) were evaluated by spectrophotometry and by the oxygen radical absorbance capacity (ORAC), respectively. A positive and significant correlation between serum levels of MDA and LAP (r = 0.162, p = 0.010) was observed. This relationship was stronger in women (r = 0.189, p = 0.013) than in men. The association between them remained significant after adjusting for confounders (r = 0.23, p < 0.001). A cutoff of LAP of 73.73 predicts high levels of MDA in women aged between 40 and 59. LAP index was associated with OS biomarkers in women and men from Yucatan, Mexico. Therefore, the elevation of the LAP index could identify an imbalance in the redox status.

Bioeconomy moving forward step by step - A global journey.

Continuous, inspiring and interconnected step-by-step changes in thought and understanding, knowhow, actions and behaviour have often been instrumental in transitions from one particular age to the next in human history. This also applies to the present century and its sustainability challenges at the planetary, regional and local levels. Therefore, it is of great importance and relevance to move forward on the journey which has been started globally to address the not insignificant number of challenges. It is however essential to go beyond descriptive work by continuing with novel, inspiring and interconnected steps to find solutions to overcome these challenges. As this huge task also requires multidimensional communication, understanding and actions across different regions, cultures, disciplines and knowledge areas, the development of a common conceptual framework such as the concept of bioeconomy has been accepted globally as very valuable. The momentum which has been created in more than 50 countries around the world by the growing number of activities, initiatives and strategies in bioeconomy is very encouraging. This offers great opportunities to mobilize even more stakeholders in science and industry, as well as society, to join the bioeconomy journey. Strategic high-level concepts such as preserving the value of the natural capital of planet earth, connecting economy and ecology, sustaining the boundary conditions and habitability of our biosphere are highly important. It is also essential on the bioeconomy journey to connect with highly specific and actionable missions, programs and plans towards sustainable economic growth under the boundary conditions of our planet.

Telemedicine and the current opportunities for the management of oncological patients in Peru in the context of COVID-19 pandemic.

COVID-19 pandemic is the more challenging public health emergency of the century, producing the collapse of health systems and unprecedented levels of morbidity and mortality around the world, especially in low resource settings. Patients with chronic diseases are the most affected, not only due to the high susceptibility to SARS-CoV-2 infection but also due to the decrease in opportunities for timely care. In this dark landscape, telemedicine, before limited to very specific scenarios, has become one of our main tools to manage cancer patients, particularly in Latin America where COVID-19 has had a strong impact on the public health. Telemedicine can provide rapid access to specialized cancer care in a scenario complicated, reducing the exposure of patients and healthcare personnel to the SARS-CoV-2. In this review, we would like to share our experience and our workflow using telemedicine at Oncosalud-AUNA, a private clinic in Peru.

Impact of the Delayed Initiation of Adjuvant Chemotherapy in the Outcome of Triple Negative Breast Cancer.

BACKGROUND: Adjuvant chemotherapy decreases the recurrence risk and improves survival rates; however, it is unclear whether a delayed initiation is associated with adverse outcomes, especially in triple negative breast cancer (TNBC). In this study, we evaluated the influence of the time to start adjuvant chemotherapy (TTC) in the outcomes of TNBC. PATIENTS AND METHODS: We retrospectively analyzed 15 years of data from patients with TNBC who received adjuvant chemotherapy at the Instituto Nacional de Enfermedades Neoplasicas (Lima, Peru). TTC was categorized into 4 groups: ≤ 30, 31 to 60, 61 to 90, and ≥ 91 days. We evaluated overall survival (OS) and distant recurrence-free survival (DRFS). Cox proportional hazard models were used to identify prognostic factors. RESULTS: In total, 687 patients were included. The mean age at diagnosis was 49.1 years (SD, 11.8 years), and most (62.6%) patients had pathologic stage T2. The median TTC was 48.1 days (SD, 27.4 days); 189 (27.5%) received chemotherapy ≤ 30 days; 329 (47.9%), between 31 and 60 days; 115 (16.7%), between 61 and 90 days; and 54 (7.9%) in ≥ 90 days. In the multivariate analysis, a TTC between 31 and 60 days (hazard ratio [HR], 1.78; 95% confidence interval [CI], 1.17-2.72), 61 and 90 days (HR, 2.38; 95%CI, 1.43-3.97), and ≥ 91 days (HR, 2.45; 95% CI, 1.32-4.55) was associated with an increased mortality in contrast with a TTC < 30 days. Although a TTC between 31 and 60 days, 61 and 90 days, and ≥ 91 days was associated with an increased risk of DRFS (HR, 1.86; 95% CI, 1.24-2.79; HR, 2.34, 95% CI, 1.42-3.867; and HR, 3.16; 95% CI, 1.78-5.61, respectively). CONCLUSION: A delaying in TTC ≥ 30 days was associated with poorer outcomes. Our data suggest that several efforts should be conducted to avoid a delayed TTC in patients with TNBC.

Elucidating the Neuropathologic Mechanisms of SARS-CoV-2 Infection.

The current pandemic caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a public health emergency. To date, March 1, 2021, coronavirus disease 2019 (COVID-19) has caused about 114 million accumulated cases and 2.53 million deaths worldwide. Previous pieces of evidence suggest that SARS-CoV-2 may affect the central nervous system (CNS) and cause neurological symptoms in COVID-19 patients. It is also known that angiotensin-converting enzyme-2 (ACE2), the primary receptor for SARS-CoV-2 infection, is expressed in different brain areas and cell types. Thus, it is hypothesized that infection by this virus could generate or exacerbate neuropathological alterations. However, the molecular mechanisms that link COVID-19 disease and nerve damage are unclear. In this review, we describe the routes of SARS-CoV-2 invasion into the central nervous system. We also analyze the neuropathologic mechanisms underlying this viral infection, and their potential relationship with the neurological manifestations described in patients with COVID-19, and the appearance or exacerbation of some neurodegenerative diseases.

Biotechnology as the engine for the Knowledge-Based Bio-Economy.

The European Commission has defined the Knowledge-Based Bio-Economy (KBBE) as the process of transforming life science knowledge into new, sustainable, eco-efficient and competitive products. The term "Bio-Economy" encompasses all industries and economic sectors that produce, manage and otherwise exploit biological resources and related services. Over the last decades biotechnologies have led to innovations in many agricultural, industrial, medical sectors and societal activities. Biotechnology will continue to be a major contributor to the Bio-Economy, playing an essential role in support of economic growth, employment, energy supply and a new generation of bio-products, and to maintain the standard of living. The paper reviews some of the main biotechnology-related research activities at European level. Beyond the 7th Framework Program for Research and Technological Development (FP7), several initiatives have been launched to better integrate FP7 with European national research activities, promote public-private partnerships and create better market and regulatory environments for stimulating innovation.

Biodiplomacy, the new frontier for bioeconomy.

Most of the initiatives to adapt, reduce and mitigate the effects of global challenges of our planet are currently dominated by the consequences of climate change. These are unintentionally overshadowing others such as food security, increase of human population, preservation of natural ecosystems, water scarcity and reliability of energy supply, amongst others. This fact tends to obscure the reality that most, if not all the global challenges, are closely interdependent and need a holistic approach to deal with them in a coherent and effective way. Likewise, society at large must be made fully aware that there will not be an enduring solution unless there is a change in the level of consumption of goods and energy in affluent countries. There is an increasing perception, understanding and concern in academic circles as well as in other sectors of society that the unsustainable production and consumption of natural resources need to be tackled by novel approaches. These combined efforts should ensure that they will be enacted in policy initiatives and in the actions that pave the way to building a global biodiplomacy. This new biodiplomacy should have the courage to develop and act in the interests of the human population overall, and not be undone by the legitimate but narrower interests of any single national priority. This article concludes by highlighting some of the key elements needed to give a biodiplomacy a chance to address, effectively, responsibly and synergistically, the current global challenges that affect mankind.

Updated review on the pathophysiology of Chagas cardiomyopathy. / Revisión actualizada sobre la fisiopatología de la cardiomiopatía chagásica.

More than 110 years after Chagas disease discovery, some aspects of the mechanisms involved in the physiopathology of heart damage are still unknown. Previously, Trypanosoma cruzi was considered to be the only cause of myocardial injury. Currently, there are other known mechanisms involved in the physiopathology of Chagas heart disease, including the immune-inflammatory response, autoimmunity, microvascular abnormalities and nerve damage, which are interrelated and contribute to cardiac damage. Nowadays, the parasite is the main cause of cardiac damage during the acute stage of Chagas disease and the one that initiates the complex physiopathological network that triggers the other mentioned mechanisms. The consequence of these pathophysiological mechanisms is progressive deterioration of cardiac function that ultimately establishes Chronic Chagasic cardiomyopathy. The aim of this review is to describe and discuss the main physiopathological mechanisms that are currently being postulated with respect to cardiac damage in T. cruzi infection.

A más de 110 años del descubrimiento de la enfermedad de Chagas, aún se desconocen aspectos sobre los mecanismos implicados en la fisiopatología del daño cardiaco. Anteriormente se consideraba al Trypanosoma cruzi como el único causante de la lesión en el miocardio. Ahora se conocen otros mecanismos implicados en la fisiopatología, como la respuesta inmunitaria-inflamatoria, la autoinmunidad, las anomalías microvasculares y el daño nervioso, los cuales se encuentran interrelacionados para contribuir en el daño cardiaco. En la actualidad se reconoce al parásito como el principal causante del daño durante la etapa aguda y el que inicia la compleja red fisiopatológica que desencadena los otros mecanismos mencionados. El resultado de todos estos mecanismos fisiopatológicos es el deterioro progresivo de la función cardiaca, lo cual termina por establecer la cardiomiopatía chagásica crónica. El propósito de esta revisión es describir y discutir los principales mecanismos fisiopatológicos que se postulan con respecto al daño cardiaco en la infección por T. cruzi.

Bioeconomy for Sustainable Development.

Bioeconomy is an emerging paradigm under which the creation, development, and revitalization of economic systems based on a sustainable use of renewable biological resources in a balanced way is rapidly spreading globally. Bioeconomy is building bridges between biotechnology and economy as well as between science, industry, and society. Biotechnology, from its ancient origins up to the present is at the core of the scientific and innovative foundation of bioeconomy policies developed in numerous countries. The challenges and perspectives of bioeconomies are immense, from resource-efficient large-scale manufacturing of products such as chemicals, materials, food, pharmaceuticals, polymers, flavors, and fragrances to the production of new biomaterials and bioenergy in a sustainable and economic way for a growing world population. Key success factors for different countries working on the bioeconomy vary widely from high-tech bioeconomies, emerging diversified or diversified bioeconomies to advanced and basic primary sector bioeconomies. Despite the large variety of bioeconomies, several common elements are identified, which are simultaneously needed altogether.

Barriers in Latin America for the management of locally advanced breast cancer.

Breast cancer (BC) is a highly prevalent malignancy in Latin American women, most cases being diagnosed at locally advanced or metastatic stages when options for cancer care are limited. Despite its label as a public health problem in the region, Latin American BC patients face several barriers in accessing standard of care treatment when compared with patients from developed countries. In this review, we analyse the landscape of the four main identified barriers in the region: i) high burden of locally advanced/advanced BC; ii) inadequate access to medical resources; iii) deficient access to specialised cancer care and iv) insufficient BC research in Latin America. Unfortunately, these barriers represent the main factors associated with the BC poor outcomes seen in the region. Targeted actions should be conducted independently by each country and as a region to overcome these limitations and create an enhanced model of BC care.

Biotechnology and sustainability: the role of transatlantic cooperation in research and innovation.

Life sciences and biotechnology are increasingly providing sustainable solutions in a wide range of areas from medicine to industry, agriculture and the environment. The United States and Europe are the two largest regions in which the revolution in life sciences and biotechnology has been taking place. Established in 1990, the EC-US Task Force on Biotechnology Research has provided a fruitful forum for the exchange of information, for the discussion of ideas and for the joint sponsoring of research activities between the US and the European Union.
