    Redox imbalance in nasal epithelial cells of primary ciliary dyskinesia patients.2024-02-02

    Primary Ciliary Dyskinesia (PCD) represents a rare condition marked by an abnormal mobility pattern of cilia and flagella, resulting in impaired mucociliary clearance. This deficiency leads to recurrent infections and persistent inflammation of the airways. While previous studies have indicated heightened oxidative stress levels in the exhaled breath condensate of pediatric PCD patients, the assessment of oxidative stress within the affected respiratory tissue remains unexplored. Aims: To assess the oxidative status of human nasal epithelial cells (NECs) in PCD patients. Methods: Thirty-five PCD patients and thirty-five healthy control subjects were prospectively included in the study. Levels of reactive oxygen species (ROS), reactive nitrogen species (RNS), glutathione (GSH), intracellular Ca2+, plasma membrane potential, and oxidative damage in lipids and proteins were measured. In addition, apoptosis and mitochondrial function were analyzed by flow cytometry in NECs. Results: NECs from PCD patients showed reduced levels of apoptosis (p = 0.004), superoxide anion (O2 −, p = 0.018), peroxynitrite (ONOO−, p = 0.007), nitric oxide (NO, p = 0.007), mitochondrial hydrogen peroxide (mtH2O2, p < 0.0001), and mitochondrial superoxide anion (mtO2 −, p = 0.0004) and increased mitochondrial mass (p = 0.009) compared to those from healthy individuals. No significant differences were observed in oxidized proteins (p = 0.137) and the oxidized/reduced lipid ratio (p = 0.7973). The oxidative profile of NEC cells in PCD patients, according to their ciliary motility, recurrent otitis, recurrent pneumonia, atelectasis, bronchiectasis, and situs inversus, showed no statistically significant differences in the parameters studied. Conversely, patients with chronic rhinosinusitis exhibited lower levels of ONOO− than PCD patients without this condition, with no significant differences related to other symptoms. Conclusions: Our findings strongly suggest the presence of a redox imbalance, specifically leaning toward a reductive state, in PCD patients.

    Association between upper and lower respiratory disease among patients with primary ciliary dyskinesia: an international study.2023-11-24

    Nearly all patients with primary ciliary dyskinesia (PCD) report ear-nose-throat (ENT) symptoms. However, scarce evidence exists about how ENT symptoms relate to pulmonary disease in PCD. We explored possible associations between upper and lower respiratory disease among patients with PCD in a multicentre study. Methods We included patients from the ENT Prospective International Cohort (EPIC-PCD). We studied associations of several reported ENT symptoms and chronic rhinosinusitis (defined using patient-reported information and examination findings) with reported sputum production and shortness of breath, using ordinal logistic regression. In a subgroup with available lung function results, we used linear regression to study associations of chronic rhinosinusitis and forced expiratory volume in 1 s (FEV1) accounting for relevant factors. Results We included 457 patients (median age 15 years, interquartile range 10-24 years; 54% males). Shortness of breath associated with reported nasal symptoms and ear pain of any frequency, often or daily hearing problems, headache when bending down (OR 2.1, 95% CI 1.29-3.54) and chronic rhinosinusitis (OR 2.3, 95% CI 1.57-3.38) regardless of polyp presence. Sputum production associated with daily reported nasal (OR 2.2, 95% CI 1.20-4.09) and hearing (OR 2.0, 95% CI 1.10-3.64) problems and chronic rhinosinusitis (OR 2.1, 95% CI 1.48-3.07). We did not find any association between chronic rhinosinusitis and FEV1. Conclusion Reported upper airway symptoms and signs of chronic rhinosinusitis associated with reported pulmonary symptoms, but not with lung function. Our results emphasise the assessment and management of upper and lower respiratory disease as a common, interdependent entity among patients with PCD.

    Magnetic resonance imaging as a predictor of therapeutic response to pasireotide in acromegaly2023-10

    Objective: Hyperintensity signal in T2-weighted magnetic resonance imaging (MRI) has been related to better therapeutic response during pasireotide treatment in acromegaly. The aim of the study was to evaluate T2 MRI signal intensity and its relation with pasireotide therapeutic effectiveness in real-life clinical practice. Design, Patients and Measurements: Retrospective multicentre study including acromegaly patients treated with pasireotide. Adenoma T2-weighted MRI signal at diagnosis was qualitatively classified as iso-hyperintense or hypointense. Insulin-like growth factor (IGF-I), growth hormone (GH) and tumour volume reduction were assessed after 6 and 12 months of treatment and its effectiveness evaluated according to baseline MRI signal. Hormonal response was considered ‘complete’ when normalization of IGF-I levels was achieved. Significant tumour shrinkage was defined as a volume reduction of ≥25% from baseline. Results: Eighty-one patients were included (48% women, 50 ± 1.5 years); 93% had previously received somatostatin receptor ligands (SRLs) treatment. MRI signal was hypointense in 25 (31%) and hyperintense in 56 (69%) cases. At 12 months of follow-up, 42/73 cases (58%) showed normalization of IGF-I and 37% both GH and IGF-I. MRI signal intensity was not associated with hormonal control. 19/51 cases (37%) presented a significant tumour volume shrinkage, 16 (41%) from the hyperintense group and 3 (25%) from the hypointense. Conclusions: T2-signal hyperintensity was more frequently observed in pasireotide treated patients. Almost 60% of SRLs resistant patients showed a complete normalization of IGF-I after 1 year of pasireotide treatment, regardless of the MRI signal. There was also no difference in the percentage tumour shrinkage over basal residual volume between the two groups.

    Thyrotoxicosis following SARS-COV-2 vaccination: a case series and discussion2022-05

    Aim: To describe a case series of thyrotoxicosis likely triggered by SARS-CoV-2 vaccination and to warn physicians about this potential correlation. To report clinical, laboratory and imaging findings and provide further information that goes in line with the underlying mechanisms. Methods: Single-center case series based on all the information collected in the hospital medical records, as well as the temporal sequence between the onset of symptoms and COVID-19 vaccination. Results: We report 8 cases with thyrotoxicosis after SARS-CoV-2 vaccination. 4 cases of Graves’ disease (GD), 2 cases of subacute painful thyroiditis (SAT), 1 case of concurrent GD and SAT and 1 case of atypical subacute thyroiditis. Five patients received BNT162b2 mRNA vaccine, 3 patients 1273 mRNA vaccine. The onset of symptoms following vaccination ranged from 10 to 14 days in six of eight patients and from 7 to 8 weeks in two patients. Conclusions: Several hypotheses have been proposed to explain the potential correlation between SARS-CoV-2 vaccination and thyrotoxicosis, including immune system hyper-stimulation, molecular mimicry and Autoimmune/Autoinflammatory Syndrome Induced by Adjuvants (ASIA). We should pay greater attention to thyroid disorders in patients receiving vaccine against SARS-CoV-2.

    Effects of a low-pressure hyperbaric oxygen therapy on psychological constructs related to pain and quality of life in women with fibromyalgia: a randomized clinical trial2024-06

    Background and objectives: Self-reported psychological variables related to pain have been posited as the major contributors to the quality of life of fibromyalgia (FM) women and should be considered when implementing therapeutic strategies among this population. The aim of this study was to explore the effect of low-pressure hyperbaric oxygen therapy (HBOT) on psychological constructs related to pain (i.e., pain catastrophism, pain acceptance, pain inflexibility, mental defeat) and quality of life in women with FM. Methods: This was a randomized controlled trial. Thirty-three women with FM were randomly allocated to a low-pressure hyperbaric oxygen therapy group (HBOTG) (n = 17), who received an 8-week intervention (5 sessions per week), and a control group (CG) (n = 16). All women were assessed at baseline (T0) and upon completion of the study (T1) for self-perceived pain intensity, pain catastrophism, pain acceptance, pain inflexibility, mental defeat and quality of life. Results: At T1, the HBOTG improved across all variables related to pain (i.e. self-perceived pain intensity, pain catastrophism, pain acceptance, pain flexibility, mental defeat) (p < 0.05) and quality of life (p < 0.05). In contrast, the CG showed no improvements in any variable. Furthermore, significant differences between the groups were found in quality of life (p < 0.05) after the intervention. Conclusions: HBOT is effective at improving the psychological constructs related to pain (i.e. pain catastrophism, pain acceptance, pain flexibility, mental defeat) and quality of life among women with FM.

    Effects of exercise-based interventions on inflammatory markers in patients with fibromyalgia: a systematic review and meta-analysis2024-04

    Objectives: The aim of the present review was (1) to determine the effects of exercise based-interventions (EBIs) on pro-inflammatory and anti-inflammatory biomarkers in patients with fibromyalgia (FM), and (2) to determine the most effective type (acute or maintained) and modality (aerobic, resistance, etc.). Methods: A systematic search was conducted in various electronic databases to identify all the relevant studies: Medline (PubMed), PEDro, EBSCO and Google Scholar. Clinical trials assessing the effects of EBIs in patients with FM were selected. Methodological quality was evaluated by two independent investigators using the Cochrane Risk of Bias Tool. Qualitative analysis was based on the classification of the results into levels of evidence according to GRADE. Results: Eleven studies were included. The meta-analysis showed a statistically significant decrease in proinflammatory biomarkers by EBIs with a large clinical effect in 19 comparisons (SMD: 1.74; 95 % CI: 0.85–2.62; p < 0.05), especially for IL8. The certainty of the evidence was low. The meta-analysis showed no statistically significant increase in anti-inflammatory biomarkers (IL10) by EBIs in 6 comparisons and very low certainty of evidence. Evidence was found for acute and maintained effects of exercise, with aerobic and aquatic exercise modalities showing better improvements than resistance exercise. Conclusions: EBIs are effective in inducing an immunomodulatory response in FM, characterized by decreased pro-inflammatory signaling. However, there was no evidence of an increase in anti-inflammatory biomarkers. These results should be interpreted with caution due to low certainty of evidence.

    Factores condicionantes de la lactancia materna en tiempos de COVID-192023-11

    Objetivo: identificar los condicionantes del establecimiento y duración de la lactancia materna (LM) durante la COVID-19 desde la perspectiva de las matronas de la provincia de Castellón (España). Métodos: estudio cualitativo realizado en 2021 mediante la realización de cuatro grupos focales (GF) con matronas de la provincia de Castellón. La recolección de la información se hizo mediante videoconferencias con grabación de voz, que fueron transcritas para posterior análisis del discurso con el programa ATLAS.ti. Resultados: las matronas identificaron como facilitadores de la LM, la puesta en valor de la LM ante las madres y el fomento de la accesibilidad a recursos para solucionar situaciones problemáticas, entre otros. Como barreras refirieron ideas maternas sobre alimentación con fórmulas artificiales construidas desde su biografía, consideración social sesgada sobre el amamantamiento, falta de protocolos para extracción de calostro y déficit en la calidad de información en las redes sociales, principalmente. Reconocen que la pandemia COVID-19 produjo impactos positivos y negativos en la LM. Surgieron medidas para optimizar la promoción de la LM como aumentar la ratio matronas/madres gestantes, asistencia domiciliaria a las 24 h del alta, unificación de protocolos intercentros, ampliación a seis meses el tiempo de incorporación al trabajo y adaptación de la promoción de la LM en redes sociales. Conclusiones: se reportaron condicionantes de la lactancia emergentes del escenario sociosanitario español que sirven de base para diseñar acciones específicas de promoción. Los impactos de la pandemia COVID-19 sobre la LM deben considerarse en situaciones de confinamiento prolongado de la madre.

    Tratamiento informativo de las drogas en medios de salud en España y su relación con la agenda científica2013

    España se sitúa a la cabeza en consumo de drogas en Europa y, en particular en consumo, y prevalencia de cocaína y cannabis. Sin embargo, la percepción de las drogodependencias como un problema de salud no está instaurada en la sociedad. Con el fin de evaluar como tratan los medios técnico-profesionales especializados en salud la problemática de las drogodependencias en España, se analizan en este estudio la cobertura de información, las sustancias referidas y el valor de intensidad formal de un total de 147 textos, comparándolos con la cobertura hallada en agenda científica en un período de 6 meses. La metodología aplicada es el análisis de contenido de tipo categorial y evaluativo. Los resultados obtenidos indican que la cobertura en estos medios es reducida, la presencia de noticias relacionadas con la cocaína y el cannabis es baja, especialmente en comparación con la agenda científica y que la intensidad con que se tratan esta problemática es media. Todo ello, permite concluir que la problemática de las drogodependencias no es un tema prioritario en la agenda mediática de los soportes, técnico profesionales existiendo diferencias significativas en relación a la agenda científica.

    Confident perception of primary care physicians correlates to the attitude toward donation and organ transplantation: a multicenter study of medical and nursing Spanish students2020-03

    A primary care physician (PCP) not only accompanies the patient in the process of an illness, but throughout his or her life. The confidence we have in these health professionals is fundamental, and their favorable attitude toward organ donation and transplantation (ODT) has a significant influence on the population. Objective: To analyze trust in PCPs among Spanish medical and nursing students, the relationship with their attitude toward ODT, and the factors that condition it. Methods and Design: A sociologic, multicenter, and observational study. Population: medical and nursing students in Spanish universities. Database: Collaborative International Donor Project, stratified by geographic area and academic course. A validated questionnaire (PCID-DTO-RIOS) was self-administered and completed anonymously. A sample of 9598 medical and 10,566 nursing students (99% confidence and precision of ±1%), stratified by geographic area and year of study. Results: Completion rate: 90%. With respect to students’ trust in their physician, 18% (n = 3267) of them totally trust (completely), 45% (n = 8101) trust enough, 30% (n = 5478) of them have not enough trust, and 7% not at all. Comparing groups, medical students totally trust more in PCPs than nursing students (55% vs 45%; P < .000), however, nursing students have less than enough trust in their PCP than medical students (53% vs 47%; P < .000). Students that totally trust in their PCP were more in favor toward ODT than students with not enough trust (83% vs 77%; P < .000). Conclusion: Only 18% of Spanish medical and nursing students totally trust in their PCP. Attitude toward ODT is related to a higher level of trust in PCPs among these students.

    Organ donation related with attitude toward the law of presumed consent: Spanish university medical and nursing students study2020-03

    Introduction: Information provided by health care professionals is crucial to create a climate of social opinion. This is important in organ donation and transplantation (ODT), where the participation of the general public is essential to obtain organs. Objective: To determine the attitude toward the Law of Presumed Consent (LPC) among Spanish university students and to analyze their relation with attitude toward ODT. Methods: and design. The type of study was a sociologic, multicenter, observational study. The population included medical and nursing students in Spanish universities. Database of Collaborative International Donor Project was used stratified by geographic area and academic course. A validated questionnaire (Collaborative International Donor Project, organ donation and transplantation questionnaire in Spanish [PCID-DTO-RIOS]) was self-administered and completed anonymously. A sample of 9598 medical and 10,566 nursing students was analyzed (99% confidence and precision of ±1%) and stratified by geographic area and year of study. Results: Completion rate was 90%. Regarding attitude toward LPC, 66% of the students were against the law, whereas 34% accepted it. Of the students surveyed, 9% considered the law as a gesture of solidarity, 25% as an effective way of not wasting organs, 48% as an abuse of power, and 18% as offenses against the family. Those students who were in favor of LPC also had a more favorable attitude toward ODT (86% vs 76%; P < .001). Comparing groups, nursing students were less in favor of LPC than medical students (32% vs 36%; P < .000). Conclusion: Sixty-six percent of Spanish university medical and nursing students were against the LPC. The favorable attitude toward ODT is associated with considering the law as a gesture of solidarity or as an effective way of not wasting organs.
