Enhancing the clinical research workforce: a collaborative approach with human resources.

Jobs for clinical research professionals (CRPs) have grown increasingly complex over the past 20+ years. This is due largely to additional administrative burden for investigators, study teams, sponsors, Clinical Research Organizations (CROs), and sites, particularly Academic Medical Centers (AMCs). Furthermore, National Institutes of Health (NIH) has reduced capacity to effectively fund research recognizing this is dependent on the overall congressional budget, which creates greater pressure for clinician scientists to secure external support. It is widely known clinical research will continue to become increasingly more complex for clinician scientists. This manuscript explores adoption of a clinical research competency-based job classification framework from the Joint Task Force for Clinical Trial Competency (JTFCTC) across several AMCs and the role of Human Resources (HR) in facilitating this process. This collaboration focuses on fostering successful projects tied to the business case in order to address equity and improve support for the clinical research enterprise.

Combination of protein and cell internalization SELEX identifies a potential RNA therapeutic and delivery platform to treat EphA2-expressing tumors.

The EphA2 receptor tyrosine kinase is overexpressed in most solid tumors and acts as the major driver of tumorigenesis. In this study, we developed a novel approach for targeting the EphA2 receptor using a 2'-fluoro-modified pyrimidine RNA aptamer termed ATOP. We identified the ATOP EphA2 aptamer using a novel bioinformatics strategy that compared aptamers enriched during a protein SELEX using recombinant human EphA2 and a cell-internalization SELEX using EphA2-expressing MDA231 tumor cells. When applied to EphA2-expressing tumor cell lines, the ATOP EphA2 aptamer attenuated tumor cell migration and clonogenicity. In a mouse model of spontaneous metastasis, the ATOP EphA2 aptamer slowed primary tumor growth and significantly reduced the number of lung metastases. The EphA2 ATOP aptamer represents a promising candidate for the development of next-generation targeted therapies that provide safer and more effective treatment of EphA2-overexpressing tumors.

Tratamiento médico del body packer o mulas de drogas

Introducción: Durante el año 2020, más de 284 millones de personas en el mundo se afectaron por el consumo de drogas. Estas se transportan en diferentes formas de embalaje o en el propio cuerpo y son los llamados correos humanos. Las personas que utilizan el interior del cuerpo con esos fines se describen con varios términos, entre ellos body packers o mulas de drogas. Es una práctica peligrosa, con graves consecuencias médico-legales. Se realizó una revisión bibliográfica de documentos indexados en las bases de datos SciELO, PubMed y Google académico. Se incluyeron los artículos a texto completo, en español, portugués e inglés, publicados desde 2018 hasta 2022, relacionados con el tema. Objetivo: Examinar las formas de enfrentar desde el punto de vista médico un problema de salud como el body packer. Desarrollo: En la actividad de body packer participan individuos de ambos sexos, de todos los grupos etarios. Las sustancias trasportadas son: cocaína, heroína, anfetaminas, marihuana, hachís y drogas sintéticas. Se portan entre 50 a 200 cápsulas con 5 a 10 kilogramos de la sustancia total. Para su evaluación son necesarios estudios imagenológicos que varían en sensibilidad y disponibilidad. Más del 80 % de los casos son asintomáticos, resuelven con estricta vigilancia y uso de polietilenglicol para la evacuación intestinal; el resto de los casos, desarrollan el síndrome de body packer, requieren tratamiento quirúrgico y apoyo con tratamiento sintomático y específico. Conclusiones: Para el body packer está prevista la realización de estudios imagenológicos, así como el tratamiento médico o quirúrgico según las formas clínicas que se presenten.

Introduction: During the year 2020, more than 284 million people in the world were affected by the consumption of drugs, which are transported in different forms of packaging or using the body itself, called human couriers; people who use the inside of their body for these purposes are described by various terms, including body packers or drug mules, a dangerous practice, with serious medical-legal consequences. A bibliographic review of documents indexed in the SciELO, PubMed and academic Google databases is carried out. Full text articles, in Spanish, Portuguese and English, published from 2018 to 2022, related to the topic were included. Objective: To examine the ways to deal with a health problem such as body packer from a medical point of view. Development: Individuals of both sexes, of all age groups, participate in the body packer activity. The transported substances are: cocaine, heroin, amphetamines, marijuana, hashish and synthetic drugs. Between 50 and 200 capsules with 5 to 10 kilograms of the total substance are carried. Imaging studies that vary in sensitivity and availability are necessary for its evaluation. More than 80% of cases are asymptomatic, resolve with strict surveillance and use of polyethylene-glycol for bowel evacuation; the rest of the cases develop body packer syndrome and require surgical treatment and support with symptomatic and specific treatment. Conclusions: For the body packer, imaging studies are planned, as well as medical or surgical treatment according to the clinical forms that occur.

Enfermería y la notificación espontánea de las reacciones adversas a medicamentos en Cuba / Nursing and the Spontaneous Notification of Adverse Drug Reactions in Cuba

Introducción: Los medicamentos pueden generar reacciones adversas que deben ser reportadas por los profesionales de salud y pacientes, para construir el verdadero perfil de seguridad de cualquier medicamento. Enfermería logra una relación privilegiada con el paciente, que facilita la identificación y reporte de estos medicamentos, ahora con limitaciones que requieren de acciones para mejorar la seguridad del paciente. Objetivo: Evaluar el proceso de notificación espontánea de las reacciones adversas a medicamentos por el personal de enfermería en Cuba. Métodos: Revisión sistemática realizada durante el 2021. Se tuvieron en cuenta publicaciones en español e inglés en las bases de datos SciELO, PubMed y Google académico, donde se identificaron artículos originales, libros, monografías, tesis y documentos legales, con énfasis en las publicadas desde 2017 a 2021. La pregunta guía se elaboró a través del acrónimo PICo. La estrategia de búsqueda se realizó mediante la aceptación de los Descriptores en Ciencias de la Salud (DeCS) como "enfermería", "Efectos Colaterales y Reacciones Adversas Relacionados con Medicamentos" y "farmacovigilancia" y en inglés "nursing", "Drug-Related Side Effects and Adverse Reactions", "pharmacovigilance", con los operadores booleanos AND y ORS, se utilizó el diagrama de flujo (PRISMA). El análisis de contenido permitió la interpretación de los referentes teóricos y la organización del conocimiento de la bibliografía encontrada. Conclusiones: Las notificaciones de reacciones adversas a medicamentos que realiza la enfermería cubana es pobre; a pesar de estar bien definidas sus funciones, existen limitaciones identificadas en su formación y motivación que deben ser erradicadas(AU)

ADSTRACT Introduction: Medications can produce adverse reactions that must be reported by health professionals and patients, in order to build the true safety profile of any medication. Nursing achieves a privileged relationship with the patient, which facilitates the identification and reporting about these medications, now with limitations that require actions to improve patient safety. Objective: To evaluate the spontaneous reporting process for adverse reactions to medications by nursing staffs in Cuba. Methods: A systematic review was carried out during 2021. Publications in Spanish and English were taken into account, from the SciELO, PubMed and Google Scholar databases, where original articles, books, monographs, theses and legal documents were identified, with emphasis on those published from 2017 to 2021. The guiding question was elaborated through the acronym PICO. The search strategy was performed by accepting Descriptors in Health Sciences (DeCS), both in Spanish and English, such as enfermería [nursing], Efectos Colaterales y Reacciones Adversas Relacionados con Medicamentos [Drug-Related Side Effects and Adverse Reactions] and farmacovigilancia [pharmacovigilance], using the Boolean operators AND and OR, together with the PRISMA flowchart. The content analysis allowed the interpretation of the theoretical references and the organization of the knowledge from the found bibliography. Conclusions: The notifications of adverse medication reactions made by Cuban nurses are poor. Although their functions are well defined, limitations are identified as part of their training and motivation, which should be eradicated(AU)

Integrating a Bacillus-based product with fungicides by foliar application to protect soybean: a sustainable approach to avoid exclusive use of chemicals.

BACKGROUND: Biological control is widely applied against soybean (Glycine max L.) soil-borne pathogens by furrow or seed treatments. The efficiency of bioproducts and timing of application by foliar sprays against soybean pathogens needs to be more fully understood. This work investigated the efficiency of foliar application with a Bacillus subtilis-based product (BBP) to protect soybean from multiple pathogens and the best moment to apply it considering its compatibility with fungicides. RESULTS: Foliar applications (from stages V6 to R4) with BBP, mancozeb (M) and systemic fungicides (S) applied against Asian rust (Phakopsora pachyrhizi), BBP followed by S (BBP-S), BBP along with S (S + BBP), S along with M (S + M) or water were carried out in a soybean field for two years. The treatments S + BBP, S + M and BBP-S reduced the severity of Asian rust by 82% compared to the control. Except for M, all treatments reduced the severity of other foliar diseases by >60%. The defoliation was reduced by BBP and BBP-S, whereas the yield was 25% higher than control by using BBP, S + M, S + BBP or BBP-S. Also, the incidence of Fusarium sp. was significantly reduced on seeds from treatments BBP and BBP-S. The compatibility tests in Petri dishes demonstrated that all fungicides decreased the bacterial growth when applied along with BBP, whereas previous applications of BBP did not reduce the bacterial growth. CONCLUSIONS: The BBP protected soybean against multiple pathogens, reduced defoliation and promoted soybean yield similarly to conventional fungicides, but in general, the early application of the BBP was the most efficient protection. © 2022 Society of Chemical Industry.

ABSTRACT Introduction: The proper use of medications eliminates or controls numerous diseases, contributes to the well-being of the population and increases life expectancy; but it can also generate adverse reactions, which must be reported to identify new risks and build the true safety profile of any drug. A review of articles published in the databases LILACS, PAHO, SciELO, EMBASE, PubMed and Infomed, related to the subject is carried out. Objectives: To analyze the spontaneous notification process of adverse drug reactions in Cuba. Development: The Center for International Drug Monitoring, analyzes the patterns of alleged damage they cause throughout the world, based on reports sent by member countries, including Cuba, which, through the National Coordinating Unit of Pharmacovigilance, harmonizes activity at the national level. This process has as its cornerstone the person who reports, whether he is a healthcare professional or a patient, and spontaneous notification is the most frequent way, but which may find limitations in its development, on which it must be acted upon, to acquire knowledge and skills. necessary in the search, diagnosis, report, treatment, awareness of their need and motivation. Conclusions: The Cuban pharmacovigilance system has standardized its actions and working methods, spontaneous notification of adverse drug reactions is its most important source of information. Its limitations and the way to systematically eradicate them have been identified.

Hypertension-mediated organ damage in masked hypertension.

OBJECTIVES: Masked hypertension - a blood pressure (BP) phenotype characterized by a clinic BP in the normal range but elevated BP outside the office - is associated with early hypertension-mediated organ damage. This study examined early target organ manifestations of masked hypertension diagnosed by home (HBPM) and ambulatory (ABPM) BP monitoring. METHODS: Left ventricular (LV) structure and diastolic function measured by echocardiography, microalbuminuria, and coronary artery calcification were evaluated in 420 patients with high clinic BP (SBP 120-150 mmHg or DBP 80-95 mmHg). Evidence of hypertension-mediated organ damage was compared in patients with sustained normotension, masked hypertension, and sustained hypertension based on measurements by HBPM, daytime ABPM, and 24-h ABPM. RESULTS: The 420 participants averaged 48 (12) [mean (SD)] years of age; the average clinic BP was 130 (13)/81 (8) mmHg. In individuals with masked hypertension diagnosed by HBPM, indexed LV mass, relative wall thickness, and e' and E/e' (indices of LV relaxation), were generally intermediate between values observed in normotensives and sustained hypertensive patients, and were significantly greater in masked hypertension than normotensives. Similar trends were observed when masked hypertension was diagnosed by ABPM but a diagnosis of masked hypertension was not as reliably associated with LV remodeling or impaired LV relaxation in comparison to normotensives. There were trends towards greater likelihoods of detectable urinary microalbumin and coronary calcification in masked hypertension than in normotensives. CONCLUSION: These results support previous studies demonstrating early hypertension-mediated organ damage in patients with masked hypertension, and suggest that HBPM may be superior to ABPM in identifying patients with masked hypertension who have early LV remodeling and diastolic LV dysfunction.

Identifying Strategies for Robust Survivorship Program Implementation: A Qualitative Analysis of Cancer Programs.

PURPOSE: The Commission on Cancer seeks to promote robust survivorship programs among accredited cancer programs. In practice, cancer programs' survivorship programs range from cursory (eg, developing care plans without robust services) to robust (eg, facilitating follow-up care). To inform cancer programs' future efforts, in this study, we identified the implementation strategies that cancer programs used to achieve robust survivorship programs, distinguishing them from cursory programs. METHODS: We sampled 39 cancer programs across the United States with approaches to survivorship program implementation ranging from cursory to robust on the basis of LIVESTRONG survivorship care consensus elements. Within sampled cancer programs, we conducted in-depth semistructured interviews with a total of 42 health care professionals. We used template analysis to distinguish implementation strategies used in cancer programs with robust survivorship programs from strategies that yielded cursory survivorship programs. RESULTS: Cancer programs with robust survivorship programs established clear systems survivorship care and formal committees to improve the survivorship care processes. They sought buy-in from multiple stakeholders to leverage cancer program resources and defined clear roles with shared accountability among multidisciplinary groups. By contrast, cancer programs with cursory survivorship programs reported less consistency in survivorship care processes and lacked buy-in from key stakeholders. They had limited resources, faced persistent structural concerns, and had insufficient clarity in roles among team members. CONCLUSION: Accrediting bodies may consider incorporating the implementation strategies that robust survivorship programs have used as guidance for supporting cancer programs in operationalizing survivorship care and evaluating the use of these strategies during the accreditation and review process.

Does This Adult Patient Have Hypertension?: The Rational Clinical Examination Systematic Review.

Importance: Office blood pressure (BP) measurements are not the most accurate method to diagnose hypertension. Home BP monitoring (HBPM) and 24-hour ambulatory BP monitoring (ABPM) are out-of-office alternatives, and ABPM is considered the reference standard for BP assessment. Objective: To systematically review the accuracy of oscillometric office and home BP measurement methods for correctly classifying adults as having hypertension, defined using ABPM. Data Sources: PubMed, Cochrane Library, Embase, ClinicalTrials.gov, and DARE databases and the American Heart Association website (from inception to April 2021) were searched, along with reference lists from retrieved articles. Data Extraction and Synthesis: Two authors independently abstracted raw data and assessed methodological quality. A third author resolved disputes as needed. Main Outcomes and Measures: Random effects summary sensitivity, specificity, and likelihood ratios (LRs) were calculated for BP measurement methods for the diagnosis of hypertension. ABPM (24-hour mean BP ≥130/80 mm Hg or mean BP while awake ≥135/85 mm Hg) was considered the reference standard. Results: A total of 12 cross-sectional studies (n = 6877) that compared conventional oscillometric office BP measurements to mean BP during 24-hour ABPM and 6 studies (n = 2049) that compared mean BP on HBPM to mean BP during 24-hour ABPM were included (range, 117-2209 participants per analysis); 2 of these studies (n = 3040) used consecutive samples. The overall prevalence of hypertension identified by 24-hour ABPM was 49% (95% CI, 39%-60%) in the pooled studies that evaluated office measures and 54% (95% CI, 39%-69%) in studies that evaluated HBPM. All included studies assessed sensitivity and specificity at the office BP threshold of 140/90 mm Hg and the home BP threshold of 135/85 mm Hg. Conventional office oscillometric measurement (1-5 measurements in a single visit with BP ≥140/90 mm Hg) had a sensitivity of 51% (95% CI, 36%-67%), specificity of 88% (95% CI, 80%-96%), positive LR of 4.2 (95% CI, 2.5-6.0), and negative LR of 0.56 (95% CI, 0.42-0.69). Mean BP with HBPM (with BP ≥135/85 mm Hg) had a sensitivity of 75% (95% CI, 65%-86%), specificity of 76% (95% CI, 65%-86%), positive LR of 3.1 (95% CI, 2.2-4.0), and negative LR of 0.33 (95% CI, 0.20-0.47). Two studies (1 with a consecutive sample) that compared unattended automated mean office BP (with BP ≥135/85 mm Hg) with 24-hour ABPM had sensitivity ranging from 48% to 51% and specificity ranging from 80% to 91%. One study that compared attended automated mean office BP (with BP ≥140/90 mm Hg) with 24-hour ABPM had a sensitivity of 87.6% (95% CI, 83%-92%) and specificity of 24.1% (95% CI, 16%-32%). Conclusions and Relevance: Office measurements of BP may not be accurate enough to rule in or rule out hypertension; HBPM may be helpful to confirm a diagnosis. When there is uncertainty around threshold values or when office and HBPM are not in agreement, 24-hour ABPM should be considered to establish the diagnosis.

Epigenetic regulation of adipogenesis by histone-modifying enzymes.

Many studies investigating the transcriptional control of adipogenesis have been published so far; recently the research is focusing on the role of epigenetic mechanisms in regulating the process of adipocyte development. Histone-modifying enzymes and the histone tails post-transcriptional modifications catalyzed by them, are fundamentally involved in the epigenetic regulation of adipogenesis. In our review, we will discuss recent advances in epigenomic regulation of adipogenesis with a focus on histone-modifying enzymes implicated in the various phases of adipocytes differentiation process from mesenchymal stem cells to mature adipocytes. Understanding adipogenesis, may provide new ways to treat obesity and related metabolic diseases.

Managing the risks and benefits of clinical research in response to a pandemic.

Introduction: The coronavirus disease 2019 (COVID-19) created major disruptions at academic centers and healthcare systems globally. Clinical and Translational Science Awards (CTSA) fund hubs supported by the National Center for Advancing Translational Sciences provideinfrastructure and leadership for clinical and translational research at manysuch institutions. Methods: We surveyed CTSA hubs and received responses from 94% of them regarding the impact of the pandemic and the processes employed for the protection of research personnel and participants with respect to the conduct of research, specifically for studies unrelated to COVID-19. Results: In this report, we describe the results of the survey findings in the context of the current understanding of disease transmission and mitigation techniques. Conclusions: We reflect on common practices and provide recommendations regarding lessons learned that will be relevant to future pandemics, particularly with regards to staging the cessation and resumption of research activities with an aim to keep the workforce, research participants, and our communities safe in future pandemics.

Advances in Oligonucleotide Aptamers for NSCLC Targeting.

Non-small-cell lung cancer (NSCLC) is the most common type of lung cancer worldwide, with the highest incidence in developed countries. NSCLC patients often face resistance to currently available therapies, accounting for frequent relapses and poor prognosis. Indeed, despite great recent advancements in the field of NSCLC diagnosis and multimodal therapy, most patients are diagnosed at advanced metastatic stage, with a very low overall survival. Thus, the identification of new effective diagnostic and therapeutic options for NSCLC patients is a crucial challenge in oncology. A promising class of targeting molecules is represented by nucleic-acid aptamers, short single-stranded oligonucleotides that upon folding in particular three dimensional (3D) structures, serve as high affinity ligands towards disease-associated proteins. They are produced in vitro by SELEX (systematic evolution of ligands by exponential enrichment), a combinatorial chemistry procedure, representing an important tool for novel targetable biomarker discovery of both diagnostic and therapeutic interest. Aptamer-based approaches are promising options for NSCLC early diagnosis and targeted therapy and may overcome the key obstacles of currently used therapeutic modalities, such as the high toxicity and patients' resistance. In this review, we highlight the most important applications of SELEX technology and aptamers for NSCLC handling.

Emerging Therapeutic RNAs for the Targeting of Cancer Associated Fibroblasts.

Tumor mass consists of a complex ensemble of malignant cancer cells and a wide variety of resident and infiltrating cells, secreted factors, and extracellular matrix proteins that are referred as tumor microenvironment (TME). Cancer associated fibroblasts (CAFs) are key TME components that support tumor growth, generating a physical barrier against drugs and immune infiltration, and contributing to regulate malignant progression. Thus, it is largely accepted that therapeutic approaches aimed at hampering the interactions between tumor cells and CAFs can enhance the effectiveness of anti-cancer treatments. In this view, nucleic acid therapeutics have emerged as promising molecules. Here, we summarize recent knowledge about their role in the regulation of CAF transformation and tumor-promoting functions, highlighting their therapeutic utility and challenges.

Métodos: Se realizó un estudio observacional, retrospectivo, en 77 pacientes incluidos en cuatro ensayos clínicos de Heberprot-P. Se realizó análisis de las variables examen oftalmológico antes y después del tratamiento, tipo de diabetes y años de evolución. Resultados: Se observó predominio de los diabéticos tipo 2 respecto a los tipo 1 en una razón 11:1, con una media de 16,3 años de evolución de la diabetes. La mitad de los pacientes tenían retinopatía diabética no proliferativa, con predominio de la forma leve, en el examen realizado antes del tratamiento con Heberprot-P. Solo un paciente anciano con otras comorbilidades, desarrolló una retinopatía diabética proliferativa, luego de un examen previo en que se observó retinopatía diabética no proliferativa y edema macular diabético. Conclusiones: La aparición o progresión de retinopatía diabética es infrecuente en pacientes complicados con úlcera del pie diabético tratados con Heberprot-P, hasta cinco meses después de tratamiento(AU)

Introduction: The prevalence of diabetes gradually increases worldwide and with it, the risk of microvascular complications such as diabetic retinopathy. The risk of blindness is reduced with stable metabolic control, early diagnosis and adequate treatment. Objective: To compare the result of the ophthalmological examination performed before starting treatment with Heberprot-P, with that performed five months after initiation, at different doses. Methods: A retrospective observational study was conducted in 77 patients included in four clinical trials of Heberprot-P. Analysis of the ophthalmological examination variables before and after treatment, type of diabetes and years of evolution were performed. Results: Prevalence of type 2 diabetics was observed with respect to type 1 in an 11: 1 ratio, with an average of 16.3 years of diabetes evolution. Half of the patients had nonproliferative diabetic retinopathy, predominantly of the mild form, in the examination performed before treatment with Heberprot-P. Only one elderly patient with other comorbidities developed a proliferative diabetic retinopathy, after a previous examination in which non-proliferative diabetic retinopathy and diabetic macular edema were observed. Conclusions: The appearance or progression of diabetic retinopathy is uncommon in complicated patients with diabetic foot ulcer treated with Heberprot-P, up to five months after treatment(AU)
