Evaluating silicosis risk: Assessing dust constitution and influence of water as a primary prevention measure in cutting and polishing of silica agglomerates, granite and marble.

An increasing number of silicosis cases have been reported related to the use of silica agglomerates. Many studies agree on the severity of this disease, which often presents with severe clinical forms in young workers and after a short latency period. Are there differences in the composition of dust generated by cutting and polishing with silica agglomerates versus granite and marble? Does the use of water injection reduce the risk associated with the use of these materials? We carried out a comparative observational-analytical study, measuring the concentration of dust generated during different machining operations on three different materials: granite, marble, and silica agglomerates. The effect of water injection on dust generation was evaluated. Personal sampling pumps were used, connected to a cyclone with polyvinyl chloride filters. The flow rate of the pumps was adjusted using a piston flowmeter. Measurements with a cascade impactor were made to assess the size distribution of respirable crystalline silica particles within the respirable fraction. In addition, environmental measurements with a spectrometer were made. 10 tests were carried out on granite and silica agglomerates for each procedure. In the case of marble, with very low silica content, only 2 tests of each type were carried out. Duration of each measurement was between 6 and 25 min. Cleaning times were set for each of the operations. The amount of dust collected in the respirable fraction was 70.85, 32.50 and 35.78 mg/m3 for dry cutting; 6.50, 3.75 and 3.95 mg/m3 for wet cutting; and 21.35, 13.68 and 17.50 mg/m3 for dry polishing, for granite, marble, and silica agglomerates respectively. Dry procedures in marble, silica agglomerates and granite showed higher dust concentration of particles smaller than 0.5 µm. Silica agglomerates showed higher concentrations of respirable crystalline silica particles than granite and marble, mainly with dry procedures. The greater production of small particles in dry and wet procedures with silica agglomerates shows that water injection is an insufficient preventive measure.

Novel Insights from Clinical Practice Autologous Blood Patch Pleurodesis and Endobronchial Valves for Management of Persistent Air Leaks in Two Cases of Tuberculosis.

INTRODUCTION: Pulmonary infections, such as tuberculosis, can result in numerous pleural complications including empyemas, pneumothoraces with broncho-pleural fistulas, and persistent air leak (PAL). While definitive surgical interventions are often initially considered, management of these complications can be particularly challenging if a patient has an active infection and is not a surgical candidate. CASE PRESENTATION: Autologous blood patch pleurodesis and endobronchial valve placement have both been described in remedying PALs effectively and safely. PALs due to broncho-pleural fistulas in active pulmonary disease are rare, and we present two such cases that were managed with autologous blood patch pleurodesis and endobronchial valves. CONCLUSION: The two cases presented illustrate the complexities of PAL management and discuss the treatment options that can be applied to individual patients.

External validation of the CHEDDAR score for suspected pulmonary embolism in patients with SARS-CoV-2 infection in an independent cohort.

The accuracy of the classic scores that help stratify the pretest clinical probability of pulmonary embolism (PE) in SARS-CoV-2 infection (COVID-19) is low. Therefore, to estimate the risk of PE in these patients, a new set of guidelines must be established. The recently published CHEDDAR score proposes a new diagnostic strategy to reduce the use of computed tomography pulmonary angiography (CTPA) in non-critically ill SARS-COV-2 patients with suspected PE. According to the nomogram, patients are segregated into low-risk (< 182 points) or high-risk (≥ 182 points) based on the best cut-off value to discard PE in the original cohort. We aimed to externally validate this diagnostic strategy in an independent cohort. We analyzed data from two retrospective cohorts of hospitalized non-critically ill COVID-19 patients who underwent a CTPA due to suspicion for PE. CHEDDAR score was applied. As per the CHEDDAR nomogram, patients were classified as having a low or high clinical pre-test probability. Of the 270 patients included, 69 (25.5%) had PE. Applying the CHEDDAR score, 182 (67.4%) patients could have had PE excluded without imaging. Among 58 patients classified as having high clinical pre-test probability, 39 (67.2%) had PE. Sensitivity, specificity, positive and negative predictive values, and AUC were 56%, 90%, 67%, 85%, and 0.783 (95% CI 0.71-0.85), respectively. We provide external validation of the CHEDDAR score in an independent cohort. Even though the CHEDDAR score showed good discrimination capacity, caution is required in patients classified as having low clinical pre-test probability with a D-dimer value > 3000 ng/mL, and a RALE score ≥ 4.

Psychological Attachment Orientation and Long-Term Posttraumatic Stress Symptoms Among Family Members of ICU Patients.

To determine the degree to which an ICU patient's family member having an "anxious" psychologic attachment orientation is a risk factor for developing long-term posttraumatic stress disorder (PTSD) symptoms following patient ICU discharge or death. DESIGN: Prospective cohort study. SETTING: Single academic neuroscience ICU from November 2017 to September 2020. PARTICIPANTS: Consecutively enrolled sample of family members, one for each ICU patient with a minimum length of stay of 24 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Near time of ICU discharge or patient death, we determined each participant's psychologic attachment orientation as anxious versus nonanxious via a brief standard survey tool, the Relationship Questionnaire, and measured other participant and patient characteristics as potential covariates. Six months after discharge or death, each participant completed the Impact of Events Scale-Revised (IES-R) to measure PTSD symptoms, with a score of greater than 24 indicative of clinically significant symptoms. Among 162 total participants, 10 of 27 participants (37.0%) with an anxious attachment orientation reported 6-month PTSD symptoms, compared with 24 of 135 nonanxious participants (17.8%) (relative risk, 2.08; 95% CI, 1.13-3.84; p = 0.02; risk difference 19.2%). In a subsequent univariate analysis of participant and patient covariates, anxious attachment orientation, participant Hispanic ethnicity, prior experience as a care partner of a patient with a disability, and participation in 3 or more formal ICU family meetings were all associated with 6-month PTSD symptoms. In a multiple logistic regression, anxious attachment remained an independent predictor of 6-month PTSD symptoms (odds ratio [OR], 3.64; 95% CI, 1.35-9.77; p = 0.01), as did Hispanic ethnicity (OR, 4.72; 95% CI, 1.34-16.6; p = 0.01) and participation in three or more ICU family meetings (odds ratio, 2.97; 95% CI, 1.14-7.68; p = 0.02). CONCLUSIONS: An anxious psychologic attachment orientation is associated with double the risk of long-term PTSD symptoms among family members of ICU patients. Future interventions designed to decrease risk of adverse psychologic outcomes among ICU families could be initially tested for efficacy amongst those who fall into this high-risk category.

El síndrome de Eaton Lambert: una presentación clínica inusual que suele preceder al diagnóstico oncológico / Eaton lambert syndrome: a rare clinical presentation that usually precedes oncological diagnosis

El síndrome de Eaton Lambert es un trastorno de tipo autoinmune que afecta a la unión neuromuscular. Cursa con debilidad muscular proximal y simétrica y en el 60% de los casos se asocia a una neoplasia subyacente. Dado que esta debilidad es de inicio insidioso, los pacientes suelen consultar inicialmente a su especialista de Medicina Familiar y Comunitaria. Reconocer esta entidad es fundamental para el diagnóstico precoz de la enfermedad oncológica ya que habitualmente precede en meses a los síntomas locales derivados de la enfermedad tumoral. El médico o médica de Atención Primaria tiene un papel fundamental en el adelanto diagnóstico y debe realizar una derivación precoz al medio hospitalario para completar el estudio. Presentamos un caso clínico de síndrome de Eaton Lambert paraneoplásico en el contexto de un carcinoma de pulmón de células pequeñas que trata de ilustrar esta cronología y abordar el proceso diagnóstico y terapéutico.(AU)

Eaton Lambert syndrome is an autoimmune disorder that involves the neuromuscular junction. Clinical course includes proximal muscular weakness and symmetry. In 60% of cases this is associated with underlying neoplasia. Given that this weakness is of insidious onset, patients usually initially consult their family doctor. Recognizing this condition is essential for early diagnosis of oncological disease as it usually occurs a few months prior to local symptoms arising from tumour disease. The family doctor plays a crucial role in early diagnosis and should refer early to hospital to complete the study. We report a case study of paraneoplastic Eaton Lambert syndrome in the context of a small cell lung carcinoma that tries to depict this chronology, in addition to tackling the diagnostic and therapeutic process.(AU)

Introducción. El sedentarismo es un problema de salud pública, siendo un riesgo latente para las enfermedades crónicas no trasmisibles. En un estudio previo en la Fundación Universitaria María Cano se encontró sedentarismo de 97% en estudiantes. El propósito del estudio es contribuir a la comprensión del comportamiento sedentario en estudiantes de fisioterapia, información clave para que la institución genere estrategias efectivas que incentiven la práctica físico-deportiva, considerando las motivaciones de los estudiantes. Metodología. Estudio de enfoque cuantitativo, diseño no experimental, de corte transversal. Participaron 178 estudiantes de Fisioterapia (I a VII semestre). Se aplicó un cuestionario sociodemográfico y el CAMIAF (Cuestionario de Actitudes, Motivaciones e Intereses hacia las Actividades Físico-deportivas). Resultados. Población joven, en su mayoría mujeres (77,5%), con edades entre 16 y 36 años, y media de 21,3 (DE: ±3,244). El 64% manifiesta no practicar deporte o actividad física (AF) de manera habitual. Se encuentra asociación significativa de la edad con los factores competencia (todas las variables), capacidad personal (por superarse), aventura (relacionarme y conocer gente), hedonismo (porque quiero ser celebre y popular) y forma física (para mejorar mi imagen y aspecto físico). El 92,2% de los participantes manifiestan que la Universidad motiva la práctica de AF con jornadas físicas permanentes (34,9%) y el incentivo académico (28,6%) Conclusiones. Entre las motivaciones para la práctica de AF predomina, en su orden, el factor competencia, social y recreativo, y el estético. El que genera menor motivación es el emocional. Limitaciones. El constructo motivacional es multidimensional; un abordaje cualitativo adicional podría mejorar la comprensión de los hallazgos.

Introduction. Sedentary lifestyle is a public health problem, being a latent risk for chronic non-communicable diseases. In a previous study at Fundación Universitaria María Cano, a sedentary lifestyle of 97% was found in students. The purpose of the study is to contribute to the understanding of sedentary behavior in physical therapy students, which is a key information for the institution to generate effective strategies to encourage sports and physical practice, considering the students' motivations. Methodology. A quantitative approach study, with a non-experimental and cross-sectional design. 178 physiotherapy students (1st to 7th semester) participated. A sociodemographic questionnaire and the CAMIAF (Questionnaire of Attitudes, Motivations, and Interests towards Physical-Sports Activities) were applied. Results. Young population, mostly women (77.5%), aged between 16 and 36, with an average of 21.3 (SD: ±3.244). Sixty-four percent stated that they did not practice sport or physical activity (PA) on a regular basis. A significant association was found between age and the following factors: competence (all variables), personal capacity (for self-im-provement), adventure (to socialize and meet people), hedonism (because I want to be famous and popular), and physical fitness (to improve my image and physical appear-ance). 92.2% of the participants state that the University motivates the practice of PA with permanent physical sessions (34.9%) and academic incentive (28.6%). Conclusions. Among the motivations for the practice of PA, the following factors predominate in this order: competition, social and recreational, and aesthetic. The least motivating factor was the emotional one.Limitations. The motivational construct is multidimensional; an additional quali-tative approach could improve the understanding of the findings.

The Impact of Spaceflight and Microgravity on the Human Islet-1+ Cardiovascular Progenitor Cell Transcriptome.

Understanding the transcriptomic impact of microgravity and the spaceflight environment is relevant for future missions in space and microgravity-based applications designed to benefit life on Earth. Here, we investigated the transcriptome of adult and neonatal cardiovascular progenitors following culture aboard the International Space Station for 30 days and compared it to the transcriptome of clonally identical cells cultured on Earth. Cardiovascular progenitors acquire a gene expression profile representative of an early-stage, dedifferentiated, stem-like state, regardless of age. Signaling pathways that support cell proliferation and survival were induced by spaceflight along with transcripts related to cell cycle re-entry, cardiovascular development, and oxidative stress. These findings contribute new insight into the multifaceted influence of reduced gravitational environments.

Psychological Attachment Orientations of Surrogate Decision-Makers and Goals-of-Care Decisions for Brain Injury Patients in ICUs.

To determine whether ICU surrogates with "insecure" psychologic attachment orientations are more prone to requesting tracheostomy and gastrostomy (i.e., life-sustaining therapy) for severe acute brain injury patients with poor prognosis compared to surrogates with "secure" orientations. DESIGN: Cross-sectional survey from November 2017 to August 2018. SETTING: Single neuroscience ICU at an academic medical center. SUBJECTS: Consecutive sample of surrogates of patients admitted to the ICU with a minimum length of stay of 24 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We identified surrogates' psychologic attachment orientation via a standard tool, the Relationship Questionnaire, and collected other surrogate and patient demographics. We also presented surrogates with a hypothetical scenario of an intubated severe acute brain injury patient with poor prognosis and asked each surrogate whether he or she would request life-sustaining therapy or comfort measures only. Fisher exact test was used to compare frequency of life-sustaining therapy selection between secure and insecure surrogates. Additionally, we conducted univariate and multivariate analyses to determine other independent predictors of life-sustaining therapy selection. Two-hundred seventy-five of 713 (38.6%) eligible respondents participated; 153 (55.6%) surrogates were secure, and 122 (44.4%) insecure. There was no significant difference in the proportion of secure respondents selecting life-sustaining therapy compared to insecure (18.3% vs 20.5%; p = 0.38). Although still nonsignificant, the observed difference was slightly greater for those with a specific "anxious" insecure subtype versus "nonanxious" (18.2% vs 23.0%; p = 0.41). Overall, a higher proportion of respondents selecting life-sustaining therapy (vs comfort measures only) reported feeling uncertain or very uncertain about the hypothetical decision (45.3% vs 9.5%; p < 0.001). In a multivariate model, nonwhite race and high religiosity were significant predictors of life-sustaining therapy selection. CONCLUSIONS: Although surrogate attachment orientation is not predictive of life-sustaining therapy selection, nonwhite race and high religiosity are. Future interventions designed to support severe acute brain injury surrogates could focus on surrogates prone to selecting life-sustaining therapy with high degrees of uncertainty.

Cardiovascular progenitor cells cultured aboard the International Space Station exhibit altered developmental and functional properties.

The heart and its cellular components are profoundly altered by missions to space and injury on Earth. Further research, however, is needed to characterize and address the molecular substrates of such changes. For this reason, neonatal and adult human cardiovascular progenitor cells (CPCs) were cultured aboard the International Space Station. Upon return to Earth, we measured changes in the expression of microRNAs and of genes related to mechanotransduction, cardiogenesis, cell cycling, DNA repair, and paracrine signaling. We additionally assessed endothelial-like tube formation, cell cycling, and migratory capacity of CPCs. Changes in microRNA expression were predicted to target extracellular matrix interactions and Hippo signaling in both neonatal and adult CPCs. Genes related to mechanotransduction (YAP1, RHOA) were downregulated, while the expression of cytoskeletal genes (VIM, NES, DES, LMNB2, LMNA), non-canonical Wnt ligands (WNT5A, WNT9A), and Wnt/calcium signaling molecules (PLCG1, PRKCA) was significantly elevated in neonatal CPCs. Increased mesendodermal gene expression along with decreased expression of mesodermal derivative markers (TNNT2, VWF, and RUNX2), reduced readiness to form endothelial-like tubes, and elevated expression of Bmp and Tbx genes, were observed in neonatal CPCs. Both neonatal and adult CPCs exhibited increased expression of DNA repair genes and paracrine factors, which was supported by enhanced migration. While spaceflight affects cytoskeletal organization and migration in neonatal and adult CPCs, only neonatal CPCs experienced increased expression of early developmental markers and an enhanced proliferative potential. Efforts to recapitulate the effects of spaceflight on Earth by regulating processes described herein may be a promising avenue for cardiac repair.

Short-term hypoxia improves early cardiac progenitor cell function in vitro.

The use of cardiovascular progenitor cells (CPCs) to repair damaged myocardium has been the focus of intense research. Previous reports have shown that pretreatments, including hypoxia, improve cell function. However, the age-dependent effects of short-term hypoxia on CPCs, and the role of signaling in these effects, are unknown. Cloned neonatal and adult CPCs expressing Isl1, c-Kit, KDR, PDGFRA, and CXCR4, were preconditioned using hypoxia (1% O2 for six hours). Intracellular signaling pathway changes were modeled using Ingenuity Pathway Analysis (IPA), while qRT-PCR, flow cytometry, and immunoblotting were used to measure pathway activation. Cellular function, including survival, cell cycle, and invasion, were evaluated using a TUNEL assay, flow cytometry, and a Transwell® invasion assay, respectively. IPA predicted, and RT-PCR and flow cytometry confirmed, that the PI3K/AKT pathway was activated following short-term hypoxia. Heat shock protein (HSP) 40 expression increased significantly in both age groups, while HSP70 expression increased only in neonatal CPCs. Neonatal CPC invasion and survival improved after hypoxia pre-treatment, while no effect was observed in cell cycling and developmental status. Prostaglandin receptor expression was enhanced in neonatal cells. Prior to transplantation, hypoxic preconditioning enhances CPC function, including invasion ability and pro-survival pathway activation.

Spaceflight Activates Protein Kinase C Alpha Signaling and Modifies the Developmental Stage of Human Neonatal Cardiovascular Progenitor Cells.

Spaceflight impacts cardiovascular function in astronauts; however, its impact on cardiac development and the stem cells that form the basis for cardiac repair is unknown. Accordingly, further research is needed to uncover the potential relevance of such changes to human health. Using simulated microgravity (SMG) generated by two-dimensional clinorotation and culture aboard the International Space Station (ISS), we assessed the effects of mechanical unloading on human neonatal cardiovascular progenitor cell (CPC) developmental properties and signaling. Following 6-7 days of SMG and 12 days of ISS culture, we analyzed changes in gene expression. Both environments induced the expression of genes that are typically associated with an earlier state of cardiovascular development. To understand the mechanism by which such changes occurred, we assessed the expression of mechanosensitive small RhoGTPases in SMG-cultured CPCs and observed decreased levels of RHOA and CDC42. Given the effect of these molecules on intracellular calcium levels, we evaluated changes in noncanonical Wnt/calcium signaling. After 6-7 days under SMG, CPCs exhibited elevated levels of WNT5A and PRKCA. Similarly, ISS-cultured CPCs exhibited elevated levels of calcium handling and signaling genes, which corresponded to protein kinase C alpha (PKCα), a calcium-dependent protein kinase, activation after 30 days. Akt was activated, whereas phosphorylated extracellular signal-regulated kinase levels were unchanged. To explore the effect of calcium induction in neonatal CPCs, we activated PKCα using hWnt5a treatment on Earth. Subsequently, early cardiovascular developmental marker levels were elevated. Transcripts induced by SMG and hWnt5a-treatment are expressed within the sinoatrial node, which may represent embryonic myocardium maintained in its primitive state. Calcium signaling is sensitive to mechanical unloading and directs CPC developmental properties. Further research both in space and on Earth may help refine the use of CPCs in stem cell-based therapies and highlight the molecular events of development.

Preliminary Results of a New Auxiliary Mechatronic Near-Field Radar System to 3D Mammography for Early Detection of Breast Cancer.

Accurate and early detection of breast cancer is of high importance, as it is directly associated with the patients' overall well-being during treatment and their chances of survival. Uncertainties in current breast imaging methods can potentially cause two main problems: (1) missing newly formed or small tumors; and (2) false alarms, which could be a source of stress for patients. A recent study at the Massachusetts General Hospital (MGH) indicates that using Digital Breast Tomosynthesis (DBT) can reduce the number of false alarms, when compared to conventional mammography. Despite the image quality enhancement DBT provides, the accurate detection of cancerous masses is still limited by low radiological contrast (about 1%) between the fibro-glandular tissue and affected tissue at X-ray frequencies. In a lower frequency region, at microwave frequencies, the contrast is comparatively higher (about 10%) between the aforementioned tissues; yet, microwave imaging suffers from low spatial resolution. This work reviews conventional X-ray breast imaging and describes the preliminary results of a novel near-field radar imaging mechatronic system (NRIMS) that can be fused with the DBT, in a co-registered fashion, to combine the advantages of both modalities. The NRIMS consists of two antipodal Vivaldi antennas, an XY positioner, and an ethanol container, all of which are particularly designed based on the DBT physical specifications. In this paper, the independent performance of the NRIMS is assessed by (1) imaging a bearing ball immersed in sunflower oil and (2) computing the heat Specific Absorption Rate (SAR) due to the electromagnetic power transmitted into the breast. The preliminary results demonstrate that the system is capable of generating images of the ball. Furthermore, the SAR results show that the system complies with the standards set for human trials. As a result, a configuration based on this design might be suitable for use in realistic clinical applications.

Transplanted Human Stem Cell-Derived Interneuron Precursors Mitigate Mouse Bladder Dysfunction and Central Neuropathic Pain after Spinal Cord Injury.

Neuropathic pain and bladder dysfunction represent significant quality-of-life issues for many spinal cord injury patients. Loss of GABAergic tone in the injured spinal cord may contribute to the emergence of these symptoms. Previous studies have shown that transplantation of rodent inhibitory interneuron precursors from the medial ganglionic eminence (MGE) enhances GABAergic signaling in the brain and spinal cord. Here we look at whether transplanted MGE-like cells derived from human embryonic stem cells (hESC-MGEs) can mitigate the pathological effects of spinal cord injury. We find that 6 months after transplantation into injured mouse spinal cords, hESC-MGEs differentiate into GABAergic neuron subtypes and receive synaptic inputs, suggesting functional integration into host spinal cord. Moreover, the transplanted animals show improved bladder function and mitigation of pain-related symptoms. Our results therefore suggest that this approach may be a valuable strategy for ameliorating the adverse effects of spinal cord injury.

Normativa para el diagnóstico y seguimiento de la silicosis / Guidelines for the Diagnosis and Monitoring of Silicosis

La silicosis es una de las enfermedades respiratorias de origen ocupacional más frecuentes en nuestro entorno. Está ocasionada por inhalación de sílice cristalina que desencadena una respuesta fibrótica en el parénquima pulmonar. Se presenta como una enfermedad intersticial difusa y su expresión clínica es variable, existiendo desde formas asintomáticas hasta la insuficiencia respiratoria crónica. El diagnóstico está basado en la historia clínica y los hallazgos radiológicos; no tiene un tratamiento efectivo, y cuando se diagnostica precisa que el paciente sea apartado de toda fuente de exposición laboral. Esta normativa repasa aspectos clínicos, radiológicos y funcionales, sugiriendo también estrategias de diagnóstico y seguimiento para la clasificación de los pacientes, y recomendaciones para las implicaciones laborales de esta enfermedad

Silicosis is one of the occupational respiratory diseases most commonly encountered in our setting. It is caused by inhalation of crystalline silica that triggers a fibrotic response in the lung parenchyma. It presents as diffuse interstitial disease and clinical expression ranges from asymptomatic forms to chronic respiratory failure. Diagnosis is based on clinical history and radiological findings. There is no effective treatment, and once diagnosed, the patient must avoid all sources of occupational exposure. In these guidelines, the clinical, radiological and functional aspects of silicosis are reviewed, and strategies for diagnosis, monitoring and classification of patients are proposed, along with recommendations regarding the occupational implications of this disease
