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.

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.

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.

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.

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.

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.

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.

Aim: To analyze the attitude of university nursing students at Spanish universities toward organ donation and transplantation and the factors affecting to their attitude. Background: The opinion of future nurses toward organ transplant donation could have an important influence on the population. Knowing that opinion and what factors influence it is important to improve the attitude towards organ donation and transplantation. Design: A multicenter, sociological, interdisciplinary and observational study including university nursing diploma students in a complete academic year. Methods: Selected and randomized sample was taken of students from 52 of the 111 faculties and nursing schools and faculties in Spain with teaching activity PARTICIPANTS: A sample of 10,566 students was selected stratified by geographical area and year. Measurement instrument: The instrument used was a validated questionnaire of attitude toward organ donation and transplantation, self-administered and completed anonymously. Results: Completion rate: 85 % (n = 9001). Of the students surveyed, 78 % (n = 7040) would donate their organs after dying. Variables related to a favourable attitude: (1) Interest in listening to a talk about organ donation and transplantation [Odds ratio 1.66, 95 % confidence interval 2.05-1.35]; (2) Family discussion [Odds ratio 2.30, 95 % confidence interval 2.79-1.90] or discussion with friends about organ donation and transplantation [Odds ratio 1.56, 95 % confidence interval 1.86-1.31]; (3) Knowing that one's father [Odds ratio 1.54, 95 % confidence interval 1.94-1.22], mother's [Odds ratio 1.44, 95 % confidence interval 1.82-1.13] or partner [Odds ratio 1.28, 95 % confidence interval 1.60-1.03] has a favourable opinion; (4) Having a good self-assessment of information about organ donation and transplantation [Odds ratio 2.94, 95 % confidence interval 4.90-1.78]; (5) Not being worried about possible mutilation of the body after donation [Odds ratio 2.73, 95 % confidence interval 3.36-1.72]. Conclusions: Nursing students in Spain tend to have a favourable attitude toward organ donation and transplantation although more than 20 % of those surveyed are not in favour. Tweetable abstract: To maintain a high rate of organ donation for organ transplantation, it is necessary to improve the social awareness of future generations of nurses towards organ donation.

Inflammatory cytokines are involved in attention deficit hyperactivity disorder (ADHD), a highly prevalent neurodevelopmental disorder. To quantify the baseline levels of pro- and anti-inflammatory cytokines and their changes after methylphenidate (MPH), a total of 31 prepubertal children with ADHD were recruited and subclassified into only two ADHD presentations—ADHD attention deficit (n = 13) or ADHD combined (n = 18). The children were also screened for oppositional defiant conduct disorder (ODCD) and anxiety disorder. Blood samples were drawn at 09:00 and after 4.63 ± 1.87 months of treatment. Four pro-inflammatory cytokines (interleukin-1beta (IL-1β), IL-5, IL-6, tumor necrosis factor-alpha (TNF-α)) and three anti-inflammatory cytokines (IL-4, IL-10, IL-13) were measured using a Luminex® assay. For statistics, a factorial analysis was performed in Stata 15.1. Overall, there were no statistically significant differences in the interleukin (IL) values induced by treatment. When grouped by presentation, the differences were present almost exclusively in ADHD-AD, usually with a profile opposite to that observed in ADHD-C, and with interactions between comorbid factors, with IL-1β (p = 0.01) and IL-13 (p = 0.006) being the ones reaching the greatest statistical significance. These differences are probably related to the ODCD factor, and they disappear after treatment. In conclusion, the changes observed in cytokine levels in prepubertal children only in the ADHD-AD presentation are probably related to comorbidities (specifically ODCD) and are mitigated after treatment.
