[Taurolidine lock in pediatric patients with intestinal failure. A practical guideline from the Spanish Society of Pediatric Gastroenterology, Hepatology and Nutrition (SEGHNP)]. / Sellado con taurolidina en el fracaso intestinal pediátrico. Guía práctica de la Sociedad Española de Gastroenterología, Hepatología y Nutrición Pediátrica (SEGHNP).

OBJECTIVES: the prevention of central line-associated bloodstream infections is a critical aspect of care for patients with intestinal failure who are treated with parenteral nutrition. The use of taurolidine in this context is becoming increasingly popular, however there is a lack of standardization in its pediatric application. The objective of this work is to develop a guide to support its prescription. METHODOLOGY: the guide is based on a review of the literature and expert opinions from the Intestinal Failure Group of the SEGHNP. It was developed through a survey distributed to all its members, addressing aspects of usual practice with this lock solution. RESULTS: this manuscript presents general recommendations concerning taurolidine indications, commercial presentations, appropriate forms of administration, use in special situations, adverse reactions, and contraindications in the pediatric population Conclusions: taurolidine is emerging as the primary lock solution used to prevent central line-associated bloodstream infections, proving to be safe and effective. This guide aims to optimize and standardize its use in pediatrics.

Implementation of a roadmap for the comprehensive diagnosis, follow-up, and research of childhood leukemias in vulnerable regions of Mexico: results from the PRONAII Strategy.

The main objective of the National Project for Research and Incidence of Childhood Leukemias is to reduce early mortality rates for these neoplasms in the vulnerable regions of Mexico. This project was conducted in the states of Oaxaca, Puebla, and Tlaxcala. A key strategy of the project is the implementation of an effective roadmap to ensure that leukemia patients are the target of maximum benefit of interdisciplinary collaboration between researchers, clinicians, surveyors, and laboratories. This strategy guarantees the comprehensive management of diagnosis and follow-up samples of pediatric patients with leukemia, centralizing, managing, and analyzing the information collected. Additionally, it allows for a precise diagnosis and monitoring of the disease through immunophenotype and measurable residual disease (MRD) studies, enhancing research and supporting informed clinical decisions for the first time in these regions through a population-based study. This initiative has significantly improved the diagnostic capacity of leukemia in girls, boys, and adolescents in the regions of Oaxaca, Puebla, and Tlaxcala, providing comprehensive, high-quality care with full coverage in the region. Likewise, it has strengthened collaboration between health institutions, researchers, and professionals in the sector, which contributes to reducing the impact of the disease on the community.

Dual Drug Repurposing: The Example of Saracatinib.

Saracatinib (AZD0530) is a dual Src/Abl inhibitor initially developed by AstraZeneca for cancer treatment; however, data from 2006 to 2024 reveal that this drug has been tested not only for cancer treatment, but also for the treatment of other diseases. Despite the promising pre-clinical results and the tolerability shown in phase I trials, where a maximum tolerated dose of 175 mg was defined, phase II clinical data demonstrated a low therapeutic action against several cancers and an elevated rate of adverse effects. Recently, pre-clinical research aimed at reducing the toxic effects and enhancing the therapeutic performance of saracatinib using nanoparticles and different pharmacological combinations has shown promising results. Concomitantly, saracatinib was repurposed to treat Alzheimer's disease, targeting Fyn. It showed great clinical results and required a lower daily dose than that defined for cancer treatment, 125 mg and 175 mg, respectively. In addition to Alzheimer's disease, this Src inhibitor has also been studied in relation to other health conditions such as pulmonary and liver fibrosis and even for analgesic and anti-allergic functions. Although saracatinib is still not approved by the Food and Drug Administration (FDA), the large number of alternative uses for saracatinib and the elevated number of pre-clinical and clinical trials performed suggest the huge potential of this drug for the treatment of different kinds of diseases.

Clinical Impact of Supplementation with Pasteurized Donor Human Milk by High-Temperature Short-Time Method versus Holder Method in Extremely Low Birth Weight Infants: A Multicentre Randomized Controlled Trial.

Nosocomial infections are a frequent and serious problem in extremely low birth weight (ELBW) infants. Donor human milk (DHM) is the best alternative for feeding these babies when mother's own milk (MOM) is not available. Recently, a patented prototype of a High-Temperature Short-Time (HTST) pasteurizer adapted to a human milk bank setting showed a lesser impact on immunologic components. We designed a multicentre randomized controlled trial that investigates whether, in ELBW infants with an insufficient MOM supply, the administration of HTST pasteurized DHM reduces the incidence of confirmed catheter-associated sepsis compared to DHM pasteurized with the Holder method. From birth until 34 weeks postmenstrual age, patients included in the study received DHM, as a supplement, pasteurized by the Holder or HTST method. A total of 213 patients were randomized; 79 (HTST group) and 81 (Holder group) were included in the analysis. We found no difference in the frequency of nosocomial sepsis between the patients of the two methods-41.8% (33/79) of HTST group patients versus 45.7% (37/81) of Holder group patients, relative risk 0.91 (0.64-1.3), p = 0.62. In conclusion, when MOM is not available, supplementing during admission with DHM pasteurized by the HTST versus Holder method might not have an impact on the incidence of catheter-associated sepsis.

Barriers to research in family medicine-interviews with Portuguese family physician researchers.

BACKGROUND: There is a need for a deeper understanding of the barriers to research in family medicine (FM) and to consider the perceptions and perspectives of professionals. Our study aims to provide a strategic view for research capacity building in FM. We included the perspective of family physician researchers (FPR) on the existing barriers to investigation in this context. OBJECTIVES: To understand and characterize the barriers to research in FM (personal and structural), from the perspective of Portuguese family physicians who are researchers. METHODS: A qualitative study, of phenomenological nature, was performed, through the conduction of semi-structured interviews with FPR, from 2019 to 2022. Data analysis and thematic coding were done on MAxQDA®, with inductive and deductive approaches, until data saturation was reached. RESULTS: A total of 12 family physicians/researchers were interviewed. Seven main themes were identified as barriers to research: time, professional valorization, funding, ethics committees, infrastructure, management/institutions, and participants. Each theme is divided into subthemes that make it possible to assess how a barrier can affect researchers in performing research activities. CONCLUSION: Our study highlights the identification of 7 main barriers. Structuring them into sub-themes not only improved the organization of our results but also provided robust support for the next phase, namely the application of a survey with the aim of gaining a deeper insight into the repercussions that these barriers to FPR have at a national level. This research is crucial to laying the foundations for a policy document that offers well-defined and tailored recommendations to address the barriers we have uncovered.

Strategies for research capacity building by family physicians in primary healthcare: a scoping review protocol.

INTRODUCTION: The qualities of primary healthcare (PHC) make it a very relevant environment for research; however, there is still work to be done to enhance the research capabilities of family physicians in healthcare units. Considering there is no ongoing review that specifically addresses this objective, the proposed goal of this scoping review is to determine the depth of the literature on the current strategies that support research capacity building among family physicians in the context of PHC. METHODS AND ANALYSIS: The scoping review will include studies from PubMed, Scopus, Web of Science, Cochrane Library and grey literature, published from 2008 to 2023, that address strategies to promote research capacity building among family physicians in the context of PHC. Only studies published in English, Portuguese or Spanish will be considered. All study designs, including quantitative, qualitative and mixed-methods studies, will be eligible for inclusion. The literature search will be performed from January to March of 2024 and data charting will employ a descriptive-analytical method, systematically summarising study objectives, methodologies, findings and implications. This protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols and the review will employ the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. ETHICS AND DISSEMINATION: This review does not need ethical approval. Peer-reviewed publications, policy summaries, presentations at conferences and involvement with pertinent stakeholders are all part of our outreach approach.

Strategies for the Promotion of Primary Health Care Research in Portugal: A Qualitative Study.

INTRODUCTION: There are several barriers discouraging clinicians from undertaking research, including insufficient funding, lack of time, organizational issues and lack of support. The strengthening of research capacity is perceived from three levels: characteristics of the researcher, the environment, and organizational issues. To date, Portugal is lacking studies on this subject. The aim of this study was to identify the best practices to promote research in Portuguese Primary Health Care. METHODS: We conducted a qualitative study using semi-structured interviews with family doctors with broadly recognized research work and other stakeholders. We selected a sample by convenience and snowball sampling. From a total of 14 doctors invited by email, 12 responded positively, and we subsequently included two other stakeholders. We conducted the interviews in digital or face-to-face formats. Two team members handled the coding of interviews independently. We kept all recordings and transcripts confidential, only accessible to researchers. RESULTS: We identified 16 strategies: 1) increasing institutional support; 2) creating support structures; 3) redefining the residency program; 4) investing in research training; 5) redefining curriculum evaluation; 6) establishing dedicated time for research; 7) increasing funding; 8) improving access to research data; 9) being a research driver; 10) establishing a research culture; 11) working in collaboration; 12) creating formally organized research groups; 13) creating autonomous research centers; 14) improving the definition of the research subjects and study designs; 15) reviewing procedures for ethics' committees; and 16) reviewing the current selection of articles for publication. CONCLUSION: Overall, a greater proportion of interviewees identified the following as the most relevant strategies for research promotion: institutional support, including technical and scientific support from public institutions, private entities and academic centers; the reorganization of working hours with protected time for research; increased funding directed towards research and breaking isolation in research, promoting teamwork with clinicians within the same area or from different professional backgrounds.

The Influence of the Long-Term Outdoor Storage of Rockrose (Cistus laurifolius L.) Shrub Biomass on Biofuel's Quality, Pre-Treatment and Combustion Processes.

Biomass storage is an essential requirement in the supply chain of bio-refineries and power plants. This research aims to evaluate the influence of long-term outdoor storage (1 year) of baled rockrose (Cistus laurifolius L.) shrub biomass on biofuel's quality, pre-treatment processes and on combustion emissions in an industrial boiler. The raw material was obtained from different rockrose shrublands in north central Spain. A total of 233 tWM (tones of wet matter) of biomass were used to produce biofuels (30 mm of milled biomass and Ø 8 mm pellets) in the pre-treatment pilot plants at CEDER-CIEMAT. The combustion tests were conducted in an industrial moving grate boiler with a thermal power of 50 MWth, in a 17 MWe power plant. Outdoor storage improved some biofuel quality parameters, mainly the reduction in ash content, which allowed 30 mm of milled material to be classified as class I1 (ISO 17225-9:2022) and pellets as class I3 (ISO 17225-2-2021). No significant differences were observed in the total specific mass flow and energy consumption in the pre-treatment processes. The combustion tests had similar results, with the emissions being below the limits established in the directive (EU) 2015/2193. The results obtained indicated that the 1-year outdoor storage of rockrose-baled biomass, under Mediterranean conditions, was feasible for its subsequent use as biofuel.

Chikungunya virus infection in the southernmost state of Brazil was characterised by self-limited transmission (2017-2019) and a larger 2021 outbreak.

BACKGROUND: Chikungunya is a mosquito-borne virus that has been causing large outbreaks in the Americas since 2014. In Brazil, Asian-Caribbean (AC) and East-Central-South-African (ECSA) genotypes have been detected and lead to large outbreaks in several Brazilian states. In Rio Grande do Sul (RS), the southernmost state of Brazil, the first cases were reported in 2016. OBJECTIVES AND METHODS: We employed genome sequencing and epidemiological investigation to characterise the Chikungunya fever (CHIKF) burden in RS between 2017-2021. FINDINGS: We detected an increasing CHIKF burden linked to travel associated introductions and communitary transmission of distinct lineages of the ECSA genotype during this period. MAIN CONCLUSIONS: Until 2020, CHIKV introductions were most travel associated and transmission was limited. Then, in 2021, the largest outbreak occurred in the state associated with the introduction of a new ECSA lineage. CHIKV outbreaks are likely to occur in the near future due to abundant competent vectors and a susceptible population, exposing more than 11 million inhabitants to an increasing infection risk.

Small Indels in the Androgen Receptor Gene: Phenotype Implications and Mechanisms of Mutagenesis.

CONTEXT: Despite high abundance of small indels in human genomes, their precise roles and underlying mechanisms of mutagenesis in Mendelian disorders require further investigation. OBJECTIVE: To profile the distribution, functional implications, and mechanisms of small indels in the androgen receptor (AR) gene in individuals with androgen insensitivity syndrome (AIS). METHODS: We conducted a systematic review of previously reported indels within the coding region of the AR gene, including 3 novel indels. Distribution throughout the AR coding region was examined and compared with genomic population data. Additionally, we assessed their impact on the AIS phenotype and investigated potential mechanisms driving their occurrence. RESULTS: A total of 82 indels in AIS were included. Notably, all frameshift indels exhibited complete AIS. The distribution of indels across the AR gene showed a predominance in the N-terminal domain, most leading to frameshift mutations. Small deletions accounted for 59.7%. Most indels occurred in nonrepetitive sequences, with 15.8% situated within triplet regions. Gene burden analysis demonstrated significant enrichment of frameshift indels in AIS compared with controls (P < .00001), and deletions were overrepresented in AIS (P < .00001). CONCLUSION: Our findings underscore a robust genotype-phenotype relationship regarding small indels in the AR gene in AIS, with a vast majority presenting complete AIS. Triplet regions and homopolymeric runs emerged as prone loci for small indels within the AR. Most were frameshift indels, with polymerase slippage potentially explaining half of AR indel occurrences. Complex frameshift indels exhibited association with palindromic runs. These discoveries advance understanding of the genetic basis of AIS and shed light on potential mechanisms underlying pathogenic small indel events.

Pd(II) and Pt(II) Trinuclear Chelates with Spermidine: Selective Anticancer Activity towards TNBC-Sensitive and -Resistant to Cisplatin.

Triple-negative breast cancer (TNBC) is one of the most aggressive forms of breast cancer and constitutes 10-20% of all breast cancer cases. Even though platinum-based drugs such as cisplatin and carboplatin are effective in TNBC patients, their toxicity and development of cancer drug resistance often hamper their clinical use. Hence, novel drug entities with improved tolerability and selectivity profiles, as well as the ability to surpass resistance, are needed. The current study focuses on Pd(II) and Pt(II) trinuclear chelates with spermidine (Pd3Spd2 and Pt3Spd2) for evaluating their antineoplastic activity having been assessed towards (i) cisplatin-resistant TNBC cells (MDA-MB-231/R), (ii) cisplatin-sensitive TNBC cells (MDA-MB-231) and (iii) non-cancerous human breast cells (MCF-12A, to assess the cancer selectivity/selectivity index). Additionally, the complexes' ability to overcome acquired resistance (resistance index) was determined. This study revealed that Pd3Spd2 activity greatly exceeds that displayed by its Pt analog. In addition, Pd3Spd2 evidenced a similar antiproliferative activity in both sensitive and resistant TNBC cells (IC50 values 4.65-8.99 µM and 9.24-13.34 µM, respectively), with a resistance index lower than 2.3. Moreover, this Pd compound showed a promising selectivity index ratio: >6.28 for MDA-MB-231 cells and >4.59 for MDA-MB-231/R cells. Altogether, the data presently gathered reveal Pd3Spd2 as a new, promising metal-based anticancer agent, which should be further explored for the treatment of TNBC and its cisplatin-resistant forms.

One-year mortality after hospitalization for acute heart failure: Predicting factors (PRECIC study subanalysis).

INTRODUCTION AND OBJECTIVES: One-year mortality after hospitalization for heart failure (HF) is high. This study aims to identify predictive factors of one-year mortality. METHODS: This is a retrospective, single-center and observational study. All patients hospitalized for acute HF during one year were enrolled. RESULTS: A total of 429 patients were enrolled, mean age of 79 years. The in-hospital and one-year all-cause mortality rates were 7.9% and 34.3%, respectively. In the univariable analysis, the factors significantly associated with higher one-year mortality risk were: age ≥80 years (odds ratio (OR)=2.05, 95% confidence interval (CI) 1.35-3.11, p=0.001); active cancer (OR=2.93, 95% CI 1.36-6.32, p=0.008); dementia (OR=2.84, 95% CI 1.81-4.47, p<0.001); functional dependency (OR=2.63, 95% CI 1.65-4.19, p<0.001); atrial fibrillation (OR=1.86, 95% CI 1.24-2.80, p=0.004); higher creatinine (OR=2.03, 95% CI 1.29-3.21, p=0.002), urea (OR=2.92, 95% CI 1.95-4.36, p<0.001) and red cell distribution width (RDW; 4thQ OR=5.59, 95% CI 3.03-10.32, p=0.001); and lower hematocrit (OR=0.94, 95% CI 0.91-0.97, p<0.001), hemoglobin (OR=0.83, 95% CI 0.75-0.92, p<0.001) and platelet distribution width (PDW; OR=0.89, 95% CI 0.82-0.97, p=0.005). In the multivariable analysis, the independent predictors of higher one-year mortality risk were: age ≥80 years (OR=2.05, 95% CI 1.21-3.48); active cancer (OR=2.70, 95% CI 1.03-7.01); dementia (OR=2.69, 95% CI 1.53-4.74); higher urea (OR=2.97, 95% CI 1.84-4.80) and RDW (4thQ OR=5.24, 95% CI 2.55-10.76); and lower PDW (OR=0.88, 95% CI 0.80-0.97). CONCLUSIONS: Active cancer, dementia, and high values for urea and RDW at admission are predictors of one-year mortality in patients hospitalized for HF. These variables are readily available at admission and can support the clinical management of HF patients.

Orthotopic murine xenograft model of uveal melanoma with spontaneous liver metastasis.

Uveal melanoma is the most common intraocular malignancy in adults. Despite the effective primary treatment, up to 50% of patients with uveal melanoma will develop metastatic lesions mainly in the liver, which are resistant to conventional chemotherapy and lead to patient's death. To date, no orthotopic murine models of uveal melanoma which can develop spontaneous metastasis are available for preclinical studies. Here, we describe a spontaneous metastatic model of uveal melanoma based on the orthotopic injection of human uveal melanoma cells into the suprachoroidal space of immunodeficient NSG mice. All mice injected with bioluminescent OMM2.5 ( n = 23) or MP41 ( n = 19) cells developed a primary tumor. After eye enucleation, additional bioluminescence signals were detected in the lungs and in the liver. At necropsy, histopathological studies confirmed the presence of lung metastases in 100% of the mice. Liver metastases were assessed in 87 and in 100% of the mice that received OMM2.5 or MP41 cells, respectively. All tumors and metastatic lesions expressed melanoma markers and the signaling molecules insulin-like growth factor type I receptor and myristoylated alanine-rich C-kinase substrate, commonly activated in uveal melanoma. The novelty of this orthotopic mouse xenograft model is the development of spontaneous metastases in the liver from the primary site, reproducing the organoespecificity of metastasis observed in uveal melanoma patients. The faster growth and the high metastatic incidence may be attributed at least in part, to the severe immunodeficiency of NSG mice. This model may be useful for preclinical testing of targeted therapies with potential uveal melanoma antimetastatic activity and to study the mechanisms involved in liver metastasis.

Clinical nursing care protocol for convalescent plasma transfusion in patients with COVID-19.

Introduction: The treatment of COVID-19 is still challenge. So convalescent plasma can be an important alternative of treatment. Protocols with nursing care during infusion is very important to guide an effective and safety care. Objective: to analyze the evidence in the literature on the action of convalescent plasma, of the use of protocols with nursing care to use convalescent plasma and build a nursing care protocol for transfusion in patients with COVID-19. Methods: Methodological study carried out in two stages: scoping review. The search was done using the descriptors: convalescent plasma transfusion, convalescent plasma, and acute respiratory syndromes or COVID-19, to found protocols and effectiveness of convalescent plasm. Beside was done a specialist panel to build the protocol. Results: Low-evidence studies have shown improvement in the clinical signs of COVID-19 using Convalescent Plasma, reduction or elimination of viral load, benefits in the production of lymphocytes, decreases C-reactive protein, increases titers of anti-SARS-CoV-2 antibodies, positive evolution in lung involvement identified by X-rays, decrease in hospitalization. No studies were found in the databases on the protocol for clinical nursing care in plasma transfusion. Therefore, a protocol was developed with the description of clinical nursing care to be performed before, during and after the transfusion by plasma: checking of vital signs and indicative signs of transfusion reaction, measurement of oxygen saturation, assessment of venous access and checking of the level of consciousness. Conclusion: There are no evidence studies to support the use of plasma, nor anything related to bundles.

Impactos da Covid-19 em uma Unidade de Tratamento Oncológico: Percepção dos Enfermeiros na Perspectiva da Teoria das Representações Sociais / Impacts of Covid-19 in an Oncology Treatment Unit: Nurses' Perception from the Perspective of the Theory of Social Representations / Impactos del Covid-19 en una Unidad de Tratamiento Oncológico: la Percepción de los Enfermeros desde la Perspectiva de la Teoría de las Representaciones Sociales

Introdução: O novo coronavírus SARS-CoV-2, causa principal da covid-19, foi identificado em dezembro de 2019 em Wuhan, na China. Desde então, espalhou-se pelo mundo e infectou milhares de pessoas. Serviços de saúde ficaram sobrecarregados com o atendimento de pacientes acometidos pela infecção. A enfermagem neste contexto é a categoria profissional que permanece mais tempo assistindo ao paciente. Diante desses fatos, é importante apresentar as opiniões, vivências e percepções dos enfermeiros atuantes na pandemia. Objetivo: Identificar, na perspectiva de enfermeiros, os impactos da covid-19 em seu cotidiano de trabalho no cuidado às pessoas diagnosticadas com câncer. Método: Estudo descritivo qualitativo baseado na teoria das representações sociais. O cenário do estudo ocorreu em uma instituição pública federal, referência no atendimento ao câncer, com 25 enfermeiros. Os dados foram coletados por meio da técnica de entrevista semiestruturada e de um questionário sociodemográfico. A análise dos dados foi realizada pela técnica de análise de conteúdo temática. Resultados: Participaram da pesquisa 22 enfermeiras (88%) com atuação na área oncológica de oito a 30 anos. A análise resultou em quatro categorias centrais: conceitos atribuídos pelos enfermeiros à covid-19; impactos da pandemia no cotidiano dos profissionais; impactos da pandemia na instituição; e impactos da pandemia em pessoas com câncer. Conclusão: Diante de um evento pandêmico, os enfermeiros foram essenciais para o enfrentamento da covid-19. Percebeu-se que as mudanças na rotina da instituição, o uso de equipamentos de proteção individual (EPI), a redução do número de leitos e o índice de absenteísmo afetaram tanto a vida do profissional quanto a do paciente

Introduction: The new coronavirus SARS-CoV-2 the main cause of the COVID-19, was identified in December 2019 in Wuhan, China. Since then the virus has spread around the world and infected millions of people. Healthcare services have become overwhelmed with the care of patients affected by the infection. Nursing is the health professional who stays longer with the patients. Given these facts, it is essential to know the opinions, experiences, knowledge and perception of nurses while providing care to patients during the pandemic. Objective: Identify, from the perspective of nurses, the impacts of COVID-19 on their daily work in caring for individuals diagnosed with cancer. Method: Descriptive, qualitative approach study based on the theory of social representation. The study scenario was a reference federal public institution in cancer care with 25 nurses. Data were collected through a semi-structured interview technique and a sociodemographic questionnaire. Data analysis was performed using the thematic content analysis technique. Results: The participants were 22 female nurses (88%), with between eight and 30 years of experience in oncology. The analysis resulted in 4 core categories: concepts attributed by nurses to COVID-19; impacts of the pandemic on the daily lives of professionals, impacts of the pandemic on the institution and impacts of the pandemic on oncology patients. Conclusion: Even in a pandemic scenario, the nurses were essential to deal with COVID-19. Changes of the institution routine, the use of personal protective equipment (PPE), reduction of beds and absenteeism affected the lives of professionals and patients

Introducción: El nuevo coronavirus SARS-CoV-2, causa principal del COVID-19, fue identificado en diciembre de 2019 en Wuhan, China. Desde entonces, el virus se ha propagado por todo el mundo y ha infectado a millones de personas. Los servicios sanitarios fueron desbordados por la atención a los pacientes afectados por la infección. La enfermería es la clase profesional sanitaria que permanece más tiempo con los pacientes. Ante estos hechos, es fundamental presentar las opiniones, experiencias, conocimientos y percepción de los enfermeros durante la asistencia a los pacientes durante la pandemia. Objetivo: Identificar, desde la perspectiva de los enfermeros, los impactos del COVID-19 en su trabajo diario en el cuidado de personas diagnosticadas con cáncer. Método: Estudio descriptivo con enfoque cualitativo basado en la teoría de la representación social. El escenario de estudio fue en una institución pública federal de referencia en atención al cáncer, con 25 enfermeros. Los datos fueron recolectados a través de la técnica de entrevista semiestructurada y un cuestionario sociodemográfico. El análisis de los datos se realizó mediante la técnica de análisis de contenido temático. Resultados: Participaron del estudio 22 enfermeras (88%), con experiencia en el campo de la oncología entre ocho y 30 años. El análisis resultó en cuatro categorías centrales: conceptos atribuidos por los enfermeros al COVID-19; impactos de la pandemia en la vida diaria de los profesionales, impactos de la pandemia en la institución e impactos de la pandemia en los pacientes de oncología. Conclusión: Con este estudio se pudo comprobar que incluso ante un evento pandémico, los enfermeros fueron profesionales esenciales para enfrentar el COVID-19. Se percibió que los cambios en la rutina de la institución, el uso de equipos de protección personal (EPP), la reducción del número de camas y el índice de ausentismo, afectaron tanto la vida del profesional como la del paciente

Mild Androgen Insensitivity Syndrome: The Current Landscape.

OBJECTIVE: Mild androgen insensitivity syndrome (MAIS) belongs to the androgen insensitivity syndrome (AIS) spectrum, an X-linked genetic disease that is the most common cause of differences in sex development. Unfortunately, AIS studies mainly focus on the partial and complete phenotypes, and the mild phenotype (MAIS) has been barely reported. Our purpose is to explore the MAIS facets, clinical features, and molecular aspects. METHODS: We collected all reported MAIS cases in the medical literature and presented them based on the phenotype and molecular diagnosis. RESULTS: We identified 49 different androgen receptor (AR) mutations in 69 individuals in the literature. We compared the AR mutations presented in individuals with MAIS with AR mutations previously reported in other AIS phenotypes (partial and complete) regarding the type, location, genotype-phenotype correlation, and functional studies. CONCLUSION: This review provides a landscape of the mild phenotype of AIS. Most patients with MAIS present with male factor infertility. Therefore, AR gene sequencing should be considered during male factor infertility investigation, even in males with typically male external genitalia. In addition, MAIS can be part of other medical conditions, such as X-linked spinal and bulbar muscular atrophy (Kennedy disease).
