Identification and characterization of a new pathologic mutation in a large Leber hereditary optic neuropathy pedigree.

BACKGROUND: Most patients suffering from Leber hereditary optic neuropathy carry one of the three classic pathologic mutations, but not all individuals with these genetic alterations develop the disease. There are different risk factors that modify the penetrance of these mutations. The remaining patients carry one of a set of very rare genetic variants and, it appears that, some of the risk factors that modify the penetrance of the classical pathologic mutations may also affect the phenotype of these other rare mutations. RESULTS: We describe a large family including 95 maternally related individuals, showing 30 patients with Leber hereditary optic neuropathy. The mutation responsible for the phenotype is a novel transition, m.3734A > G, in the mitochondrial gene encoding the ND1 subunit of respiratory complex I. Molecular-genetic, biochemical and cellular studies corroborate the pathogenicity of this genetic change. CONCLUSIONS: With the study of this family, we confirm that, also for this very rare mutation, sex and age are important factors modifying penetrance. Moreover, this pedigree offers an excellent opportunity to search for other genetic or environmental factors that additionally contribute to modify penetrance.

Anxious and depressive symptoms and health-related quality of life in a cohort of people who recently attempted suicide: A network analysis.

BACKGROUND: Suicide is an international health concern with immeasurable impact from the perspective of human and social suffering. Prior suicide attempts, anxious and depressive symptoms, and relatively lower health-related quality of life (HRQoL) are among the most replicated risk factors for suicide. Our goal was to visualize the distribution of these features and their interconnections with use of a network analysis approach in individuals who recently attempted suicide. METHODS: Individuals with a recent suicide attempt were recruited from nine University Hospitals across Spain as part of the SURVIVE cohort study. Anxious and depressive symptoms, and perceived HRQoL were included in the network analysis. Network structures were estimated with the EBICglasso model. Centrality measures and bridge symptoms connecting communities were explored. Subnetworks comparing younger and older individuals, and women and men were analyzed. RESULTS: A total of 1106 individuals with a recent suicide attempt were included. Depressed mood was the symptom with the greatest influence in the overall network, followed by anxiety symptoms such as feeling nervous, worrying, restless, and having difficulties to relax. Perceived general health was associated with increased suicidal ideation in the whole sample. Older people showed a specific connection between perceived general health and depressed mood. LIMITATIONS: The cross-sectional design does not allow determination of established causality. CONCLUSIONS: Depressed mood was the core network's symptom and, therefore, an important target in the management and prevention of suicide. HRQoL had more influence on the network of older populations, in which it should be a primary focus.

Maternal Factors and Placental Pathologies Associated with a Diagnosis of Chronic Villitis.

OBJECTIVE: To evaluate maternal risk factors associated with chronic villitis of unknown etiology (VUE) and to describe cooccurring placental pathologies. STUDY DESIGN: A retrospective case-control study was conducted using placental pathology records from deliveries ≥ 20 weeks between 2010 and 2018. Cases were placentas with documented chronic villitis without infectious cause, hereafter called VUE. Controls were placentas without this diagnosis, matched to the cases 2:1. Maternal and neonatal demographic and clinical data were collected. Descriptive statistics are reported with Fisher's exact test or a chi-squared test, as appropriate, and multivariable conditional logistic regression was conducted. RESULTS: Our study included 352 cases with VUE and 657 controls. A diagnosis of gestational diabetes (p = 0.03) and gestational hypertension (p = 0.06) was 1.5 times more likely to occur in those with a VUE diagnosis. A trend was also seen for chronic hypertension (odds ratio [OR] = 1.7, p = 0.07) and preeclampsia (OR = 1.5, p = 0.09) compared with controls. Placentas with VUE, specifically high-grade VUE, were more likely to be small for gestational age (p = 0.01), and to be diagnosed with other placental findings including lymphoplasmacytic or chronic deciduitis (p < 0.01), maternal (p < 0.01) and fetal vascular malperfusion (p = 0.02), and chorionitis (acute or chronic; p < 0.01). CONCLUSION: Gestational diabetes and hypertension were associated with a diagnosis of VUE, and overall, VUE placentas have more abnormal placental findings compared with control. Understanding VUE risk factors may facilitate prenatal care strategies and counseling to achieve the best outcomes for pregnant patients and their neonates. KEY POINTS: · VUE is a common inflammatory lesion of the placenta.. · Gestational diabetes and hypertension are associated with a VUE diagnosis.. · Findings of other placental pathologies increase in VUE..

Safe and Successful Treatment With Pcsk9 Inhibitors in Hypercholesterolemia and Renal Transplantation: A Case Report.

BACKGROUND: Patients with chronic kidney disease (CKD) are more prone to cardiovascular disease (CVD) risks, including CVD-derived sudden death. Additionally, patients with CKD also develop lipid metabolism abnormalities. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors (PCSK9i) are drugs capable of reducing CVD risk in patients with CKD, but their efficacy is scarcely assessed in transplant patients. CASE PRESENTATION: Here, we report a case of a 74-year-old man undergoing nephrology follow-up for a cadaver donor kidney transplant. The patient described an atorvastatin allergic reaction after an acute coronary syndrome. Because the patient had a very high risk for CVD, alirocumab was substituted for atorvastatin. The patient showed a well-tolerated and effective response and stable everolimus levels. CONCLUSION: PCSK9i may be considered a pharmacologic option for treating lipid metabolism disorder and reducing low-density lipoprotein cholesterol in transplant recipients.

How the Disruption of Mitochondrial Redox Signalling Contributes to Ageing.

In the past, mitochondrial reactive oxygen species (mtROS) were considered a byproduct of cellular metabolism. Due to the capacity of mtROS to cause oxidative damage, they were proposed as the main drivers of ageing and age-related diseases. Today, we know that mtROS are cellular messengers instrumental in maintaining cellular homeostasis. As cellular messengers, they are produced in specific places at specific times, and the intensity and duration of the ROS signal determine the downstream effects of mitochondrial redox signalling. We do not know yet all the processes for which mtROS are important, but we have learnt that they are essential in decisions that affect cellular differentiation, proliferation and survival. On top of causing damage due to their capacity to oxidize cellular components, mtROS contribute to the onset of degenerative diseases when redox signalling becomes dysregulated. Here, we review the best-characterized signalling pathways in which mtROS participate and those pathological processes in which they are involved. We focus on how mtROS signalling is altered during ageing and discuss whether the accumulation of damaged mitochondria without signalling capacity is a cause or a consequence of ageing.

The Spanish version of the reflective functioning questionnaire: Validity data in the general population and individuals with personality disorders.

INTRODUCTION: Mentalization or reflective functioning (RF) is the capacity to interpret oneself or the others in terms of internal mental states. Its failures have been linked to several mental disorders and interventions improving RF have a therapeutic effect. Mentalizing capacity of the parents influences the children's attachment. The Reflective Functioning Questionnaire (RFQ-8) is a widely used tool for the assessment of RF. No instrument is available to assess general RF in Spanish-speaking samples. The aim of this study is to develop a Spanish version of the RFQ-8 and to evaluate its reliability and validity in the general population and in individuals with personality disorders. METHODS: 602 non-clinical and 41 personality disordered participants completed a Spanish translation of the RFQ and a battery of self-reported questionnaires assessing several RF related constructs (alexithymia, perspective taking, identity diffusion and mindfulness), psychopathology (general and specific) and interpersonal problems. Temporal stability was tested in a non-clinical sub-sample of 113 participants. RESULTS: Exploratory and confirmatory factor analyses suggested a one-factor structure in the Spanish version of the RFQ-8. RFQ-8 understood as a single scale was tested, with low scorings reflecting genuine mentalizing, and high scorings uncertainty. The questionnaire showed good internal consistence in both samples and moderate temporal stability in non-clinical sample. RFQ correlated significantly with identity diffusion, alexithymia, and general psychopathology in both samples; and with mindfulness, perspective taking, and interpersonal problems in clinical sample. Mean values of the scale were significantly higher in the clinical group. DISCUSSION: This study provides evidence that the Spanish version of the RFQ-8, understood as a single scale, has an adequate reliability and validity assessing failures in reflective functioning (i.e., hypomentalization) in general population and personality disorders.

Mindfulness-based cognitive therapy versus psychoeducational intervention in bipolar outpatients: Results from a randomized controlled trial.

INTRODUCTION: Few controlled trials have assessed the impact of Mindfulness Based Cognitive Therapy (MBCT) on symptoms and functioning in bipolar disorder (BD). This study aims to evaluate the effectiveness of MBCT adjunctive group treatment. MATERIAL AND METHODS: Randomized, prospective, multicenter, single-blinded trial that included BP-outpatients with subthreshold depressive symptoms. Participants were randomly assigned to three arms: treatment as usual (TAU); TAU plus psychoeducation; and TAU plus MBCT. Primary outcome was change in Hamilton-D score; secondary endpoints were change in anxiety, hypo/mania symptoms and functional improvement. Patients were assessed at baseline (V1), 8 weeks (V2) and 6 months (V3). Main hypothesis was that adjunctive MBCT would improve depressive symptoms more than psychoeducation. RESULTS: Eighty-four participants were recruited (MBCT=40, Psychoeducation=34, TAU=10). Depressive symptoms improved in the three arms between V1 and V2 (p<0.0001), and between V1 and V3 (p<0.0001), and did not change between V2 and V3. At V3 no significant differences between groups were found. There were no significant differences in other measures either. CONCLUSIONS: In our BD population we did not find superiority of adjunctive MBCT over adjunctive Psychoeducation or TAU on subsyndromal depressive symptoms; neither on anxiety, hypo/mania, relapses, or functioning.

The Suicide Prevention and Intervention Study (SURVIVE): Study protocol for a multisite cohort study with nested randomized-controlled trials.

INTRODUCTION: Suicide is one of the leading causes of avoidable death. Gathering national data on suicidal behaviour incidence is crucial to develop evidence-based public policies. The study has two primary objectives: (1) to determine the incidence of suicide attempts in Spain and related risk factors, and (2) to analyze the efficacy of secondary prevention programmes to prevent suicide re-attempting in comparison to treatment as usual (TAU). MATERIALS AND METHODS: Multisite, coordinated, cohort study with three nested randomized controlled trials. A cohort of 2000 individuals (age >=12) with suicidal behaviour will be recruited at ten sites distributed across Spain. Assessments will be conducted within 10 days of the suicide attempt (V0-baseline visit) and after 12 months (V4-last visit) and will include clinician reported and participant reported outcomes (PROs). Between V0 and V4, PROs will be collected remotely every three months (V1, V2 and V3). Optatively, cohort participants will participate in three nested randomized-controlled-trials (RCTs) evaluating different secondary prevention interventions: Participants aged 18 years and older will be randomly allocated to: Telephone-based Management+TAU vs. TAU or iFightDepression-Survive+TAU vs. TAU. Participants aged between 12 and 18 years will be allocated to a specific intervention for youths: Self Awareness of Mental Health+TAU vs. TAU. RESULTS: This study will provide interesting data to estimate suicide attempt incidence in Spain. and will provide evidence on three. CONCLUSIONS: Evidence on three potentially efficacious interventions for individuals at high risk of suicide will be obtained, and this could improve the treatment given to these individuals. TRIAL REGISTRATION: NCT04343703.

Mindfulness-based emotional regulation for patients with implantable cardioverter-defibrillators: A randomized pilot study of efficacy, applicability, and safety.

BACKGROUND: The efficacy of mindfulness-based interventions to reduce anxiety or improve quality of life (QoL) in patients with cardiac pathologies is well established. However, there is scarce information on the efficacy, applicability, and safety of these interventions in adult patients with an implantable cardioverter-defibrillator (ICD). In this study, we examined their efficacy on QoL, psychological and biomedical variables, as well as the applicability and safety of a mindfulness-based intervention in patients with an ICD. METHODS: Ninety-six patients with an ICD were randomized into two intervention groups and a control group. The interventions involved training in mindfulness-based emotional regulation, either face-to- -face or using the "REM Volver a casa" mobile phone application (app). RESULTS: The sample presented medium-high QoL baseline scores (mean: 68), low anxiety (6.84) and depression (3.89), average mindfulness disposition (128), and cardiological parameters similar to other ICD populations. After the intervention, no significant differences were found in the variables studied between the intervention and control groups. Retention was average (59%), and there were no adverse effects due to the intervention. CONCLUSIONS: After training in mindfulness-based emotional regulation (face-to-face or via app), no significant differences were found in the QoL or psychological or biomedical variables in patients with an ICD. The intervention proved to be safe, with 59% retention.

Effect of mindfulness-based cognitive therapy vs. psychoeducational intervention on plasma brain-derived neurotrophic factor and cognitive function in bipolar patients: a randomized controlled trial.

Introduction: Few controlled trials have assessed the benefits of Mindfulness Based Cognitive Therapy (MBCT) on cognitive functions and brain-derived neurotrophic factor (BDNF) in bipolar disorder (BD). This study aims to evaluate the impact of MBCT adjunctive treatment on these variables. Main hypothesis was that MBCT would improve cognitive functioning and BDNF more than Psychoeducation and TAU. Methods: Randomized, multicenter, prospective and single-blinded trial. Included BD outpatients randomly assigned to three treatment arms: MBCT plus treatment as usual (TAU), Psychoeducation plus Tau and TAU. Cognitive functions were assessed with Continuous Performance Test-III, Stroop Test, Trail Making Test, Digit Span and Letter-Number Sequencing from Wechsler Adult Intelligence Scale III, Face Emotion Identification Task and Face Emotion Discrimination Task. BDNF serum level was measured with ELISA. Patients were assessed at baseline, 8 weeks and 6 months. Results: Eighty-four patients were recruited (TAU = 10, Psychoeducation = 34, MBCT = 40). No significant differences between treatment groups were found. MBCT does not achieve better results than Psychoeducation or TAU. Discussion: Being Psychoeducation and TAU efficient interventions, as well as the scarce duration of a more complex intervention, such as MBCT, are suggested as explanatory variables of these results. Trial registration: ClinicalTrials.gov: NCT02133170. Registered 04/30/2014.

Intervención basada en mindfulness a través de una app móvil para personas con cáncer colorrectal en espera de cirugía: ensayo clínico aleatorizado / Mindfulness based intervention through mobile app for colorectal cancer people awaiting surgery: A randomized clinical trial

Introducción: El cáncer colorrectal representa el tercer cáncer con mayor incidencia en ambos sexos. Un tercio de los pacientes con cáncer experimentan sintomatología ansiosa o depresiva. El objetivo de este estudio fue evaluar la eficacia de una intervención de reducción de estrés basada en mindfulness a través de una aplicación móvil (En calma en el quirófano). Método: Es un ensayo controlado, aleatorizado, con evaluador ciego y multicéntrico, que compara la eficacia de una aplicación de entrenamiento en mindfulness para móviles (rama experimental) con tratamiento habitual (rama control), en 3tiempos de medida (T0 o línea base, T1 o alta a domicilio, T2 o un mes tras cirugía). Se evaluó la sintomatología ansiosa y depresiva (HADS), la calidad de vida (WHOQOL), la escala de dolor (EVA) y la escala de satisfacción (CSQ). Resultados: Hubo un total de 270 derivaciones. Fueron analizadas 82 personas: 39 personas utilizaron la app y 43 continuaron su tratamiento habitual. No hubo cambios significativos entre grupos ni tiempos de medida. Se observó una ligera tendencia en la que el grupo experimental tuvo menos síntomas de depresión y ansiedad entre T0 y T2 (B?= −0,2; IC 95%: 8,8-9,2). Conclusiones: Nuestra población mostraba una edad media alta (65 años), niveles bajos de ansiedad y depresión, y niveles medios de calidad de vida en T0. Estos factores podrían haber interactuado y limitado la eficacia de la app. Nuevas líneas de investigación tienen que ir dirigidas a evaluar la eficacia de las apps para pacientes con enfermedades quirúrgicas en poblaciones más jóvenes.

Introduction: Colorectal cancer is the third most common cancer worldwide that occurs both in men and women. Around one-third of patients with cancer will suffer from anxiety or depression symptoms. The aim of this study was to evaluate the effectiveness of a mindfulness-based stress reduction intervention through a mobile application («en calma en el quirófano»). Method: This study is a multicenter, single-blind (evaluator), controlled, randomized trial that compares the effectiveness of a mindfulness training through a mobile application (intervention group) and treatment as usual (control group) in 3different moments (T0 or baseline, T1 or hospital discharge and T2 or one month after surgery). Hospital Anxiety and depression Scale (HADS), quality of life (WHOQOL), pain (VAS) and satisfaction (CSQ) were assessed. Results: In all, there were 270 referred patients. Among them, 39 and 43 were assigned to the intervention and control groups respectively; 82 patients were analyzed: 39 patients used the app, and 43 patients continued with the treatment as usual. There were no significant changes between groups and time. We observed a slight trend in which intervention group had less depression and anxiety symptoms since T0 and T2 (B=−0.2; 95% CI: 8.8-9.2). Conclusions: The sample of this study had a high mean age (65 years old), and low levels of anxiety and depression and medium levels of pre-surgery quality of life in baseline. These factors could have influenced limiting the effectiveness of the app. Prospective research lines should focus on evaluating the effectiveness of mobile applications for younger patients with surgical pathologies.

Evaluation of Preprocessing Methods on Independent Medical Hyperspectral Databases to Improve Analysis.

Currently, one of the most common causes of death worldwide is cancer. The development of innovative methods to support the early and accurate detection of cancers is required to increase the recovery rate of patients. Several studies have shown that medical Hyperspectral Imaging (HSI) combined with artificial intelligence algorithms is a powerful tool for cancer detection. Various preprocessing methods are commonly applied to hyperspectral data to improve the performance of the algorithms. However, there is currently no standard for these methods, and no studies have compared them so far in the medical field. In this work, we evaluated different combinations of preprocessing steps, including spatial and spectral smoothing, Min-Max scaling, Standard Normal Variate normalization, and a median spatial smoothing technique, with the goal of improving tumor detection in three different HSI databases concerning colorectal, esophagogastric, and brain cancers. Two machine learning and deep learning models were used to perform the pixel-wise classification. The results showed that the choice of preprocessing method affects the performance of tumor identification. The method that showed slightly better results with respect to identifing colorectal tumors was Median Filter preprocessing (0.94 of area under the curve). On the other hand, esophagogastric and brain tumors were more accurately identified using Min-Max scaling preprocessing (0.93 and 0.92 of area under the curve, respectively). However, it is observed that the Median Filter method smooths sharp spectral features, resulting in high variability in the classification performance. Therefore, based on these results, obtained with different databases acquired by different HSI instrumentation, the most relevant preprocessing technique identified in this work is Min-Max scaling.

Neural Networks-Based On-Site Dermatologic Diagnosis through Hyperspectral Epidermal Images.

Cancer originates from the uncontrolled growth of healthy cells into a mass. Chromophores, such as hemoglobin and melanin, characterize skin spectral properties, allowing the classification of lesions into different etiologies. Hyperspectral imaging systems gather skin-reflected and transmitted light into several wavelength ranges of the electromagnetic spectrum, enabling potential skin-lesion differentiation through machine learning algorithms. Challenged by data availability and tiny inter and intra-tumoral variability, here we introduce a pipeline based on deep neural networks to diagnose hyperspectral skin cancer images, targeting a handheld device equipped with a low-power graphical processing unit for routine clinical testing. Enhanced by data augmentation, transfer learning, and hyperparameter tuning, the proposed architectures aim to meet and improve the well-known dermatologist-level detection performances concerning both benign-malignant and multiclass classification tasks, being able to diagnose hyperspectral data considering real-time constraints. Experiments show 87% sensitivity and 88% specificity for benign-malignant classification and specificity above 80% for the multiclass scenario. AUC measurements suggest classification performance improvement above 90% with adequate thresholding. Concerning binary segmentation, we measured skin DICE and IOU higher than 90%. We estimated 1.21 s, at most, consuming 5 Watts to segment the epidermal lesions with the U-Net++ architecture, meeting the imposed time limit. Hence, we can diagnose hyperspectral epidermal data assuming real-time constraints.

Effectiveness of a stepped-care programme of internet-based psychological interventions for healthcare workers with psychological distress: Study protocol for the RESPOND healthcare workers randomised controlled trial.

Background and aims: The coronavirus disease 2019 pandemic has challenged health services worldwide, with a worsening of healthcare workers' mental health within initial pandemic hotspots. In early 2022, the Omicron variant is spreading rapidly around the world. This study explores the effectiveness and cost-effectiveness of a stepped-care programme of scalable, internet-based psychological interventions for distressed health workers on self-reported anxiety and depression symptoms. Methods: We present the study protocol for a multicentre (two sites), parallel-group (1:1 allocation ratio), analyst-blinded, superiority, randomised controlled trial. Healthcare workers with psychological distress will be allocated either to care as usual only or to care as usual plus a stepped-care programme that includes two scalable psychological interventions developed by the World Health Organization: A guided self-help stress management guide (Doing What Matters in Times of Stress) and a five-session cognitive behavioural intervention (Problem Management Plus). All participants will receive a single-session emotional support intervention, namely psychological first aid. We will include 212 participants. An intention-to-treat analysis using linear mixed models will be conducted to explore the programme's effect on anxiety and depression symptoms, as measured by the Patient Health Questionnaire - Anxiety and Depression Scale summary score at 21 weeks from baseline. Secondary outcomes include post-traumatic stress disorder symptoms, resilience, quality of life, cost impact and cost-effectiveness. Conclusions: This study is the first randomised trial that combines two World Health Organization psychological interventions tailored for health workers into one stepped-care programme. Results will inform occupational and mental health prevention, treatment, and recovery strategies. Registration details: ClinicalTrials.gov Identifier: NCT04980326.

Mental health problems and needs of frontline healthcare workers during the COVID-19 pandemic in Spain: A qualitative analysis.

Background: Healthcare workers (HCWs) from COVID-19 hotspots worldwide have reported poor mental health outcomes since the pandemic's beginning. The virulence of the initial COVID-19 surge in Spain and the urgency for rapid evidence constrained early studies in their capacity to inform mental health programs accurately. Here, we used a qualitative research design to describe relevant mental health problems among frontline HCWs and explore their association with determinants and consequences and their implications for the design and implementation of mental health programs. Materials and methods: Following the Programme Design, Implementation, Monitoring, and Evaluation (DIME) protocol, we used a two-step qualitative research design to interview frontline HCWs, mental health experts, administrators, and service planners in Spain. We used Free List (FL) interviews to identify problems experienced by frontline HCWs and Key informant (KI) interviews to describe them and explore their determinants and consequences, as well as the strategies considered useful to overcome these problems. We used a thematic analysis approach to analyze the interview outputs and framed our results into a five-level social-ecological model (intrapersonal, interpersonal, organizational, community, and public health). Results: We recruited 75 FL and 22 KI interviewees, roughly balanced in age and gender. We detected 56 themes during the FL interviews and explored the following themes in the KI interviews: fear of infection, psychological distress, stress, moral distress, and interpersonal conflicts among coworkers. We found that interviewees reported perceived causes and consequences across problems at all levels (intrapersonal to public health). Although several mental health strategies were implemented (especially at an intrapersonal and interpersonal level), most mental health needs remained unmet, especially at the organizational, community, and public policy levels. Conclusions: In keeping with available quantitative evidence, our findings show that mental health problems are still relevant for frontline HCWs 1 year after the COVID-19 pandemic and that many reported causes of these problems are modifiable. Based on this, we offer specific recommendations to design and implement mental health strategies and recommend using transdiagnostic, low-intensity, scalable psychological interventions contextually adapted and tailored for HCWs.

Deep Convolutional Generative Adversarial Networks to Enhance Artificial Intelligence in Healthcare: A Skin Cancer Application.

In recent years, researchers designed several artificial intelligence solutions for healthcare applications, which usually evolved into functional solutions for clinical practice. Furthermore, deep learning (DL) methods are well-suited to process the broad amounts of data acquired by wearable devices, smartphones, and other sensors employed in different medical domains. Conceived to serve the role of diagnostic tool and surgical guidance, hyperspectral images emerged as a non-contact, non-ionizing, and label-free technology. However, the lack of large datasets to efficiently train the models limits DL applications in the medical field. Hence, its usage with hyperspectral images is still at an early stage. We propose a deep convolutional generative adversarial network to generate synthetic hyperspectral images of epidermal lesions, targeting skin cancer diagnosis, and overcome small-sized datasets challenges to train DL architectures. Experimental results show the effectiveness of the proposed framework, capable of generating synthetic data to train DL classifiers.

Pediatric Mental Health Emergency Visits During the COVID-19 Pandemic.

Introduction: Paediatric and adult psychiatric emergency department (ED) visits decreased during the initial COVID-19 outbreak. Long-term consequences of the COVID-19 pandemic will include increases in mental healthcare needs, especially among vulnerable groups such as children and adolescents. Aim: This study examined changes in the number of overall and diagnosis-specific mental health ED visits among patients aged <18 years following the onset of the COVID-19 pandemic in Madrid, Spain. Methods: Using clinical records from all psychiatric ED visits at a major teaching hospital between October 2018 and April 2021, we conducted interrupted time-series analyses and compared trends before and after the day of the first ED COVID-19 case (1st March 2020). Results: A total of 663 patients were included. In March 2020, there was a marked initial decrease of -12.8 (95% CI -21.9, - 7.9) less monthly mental health ED visits. After April 2020, there was a subsequent increasing trend of 3.4 (95% CI 2.6, 4.2) additional monthly mental health ED visits. Conclusion: After the onset of the COVID-19 pandemic, there was an increase in paediatric psychiatric ED visits, especially due to suicide-related reasons. These data reinforce the crucial role of the ED in the management of acute mental health problems among youth and highlight the need for renovated efforts to enhance access to care outside of and during acute crises during the pandemic and its aftermath.

Experiencia del personal sanitario durante la primera ola de Covid-19 en España: un estudio cualitativo con grupos focales / Experience of health workers during the first wave of Covid-19 in Spain: a qualitative study with focus groups

Objetivo: Analizar la experiencia de los profesionales que atendieron en primera línea a los pacientes infectados durante la primera ola de la pandemia de COVID-19. Material y Métodos: Los participantes fueron reclutados entre médicos y enfermeras de varios hospitales y centros de salud en España. Sus narrativas se obtuvieron a través de tres grupos focales. Se empleó la metodología cualitativa, de acuerdo con sus principios exploratorios, inductivos y etnográficos. Resultados: La experiencia del personal sanitario se clasificó en seis categorías: La reacción y organización de los sanitarios, el material y las pruebas, los aspectos emocionales en relación con la asistencia, los conflictos éticos, la gestión sanitaria de la pandemia y el papel social de los sanitarios. Conclusiones: Los sanitarios adoptaron un rol proactivo durante la pandemia. Se señalan las vulnerabilidades y las fortalezas de la asistencia. Los aspectos que tiene que ver con la regulación emocional de los sanitarios resultan claves para el funcionamiento asistencial. (AU)

Introduction. Rituximab-induced immunosuppressioncould be a risk factor for mortality from COVID-19. The aimof the study was to describe the prevalence of SARS-CoV-2infection in patients who have received rituximab and its association with a persistent viral infectionMaterial and methods. Retrospective observationalstudy of patients who received rituximab in the 6 monthsbefore to the onset of the pandemic. We analyzed thepresence of infection and associated them with demographicvariables, pathological history related to an increased riskof developing severe COVID-19, the doses of rituximabreceived, the type of ventilatory support, thromboembolicevents, and the treatment received. A descriptive analysis ofall the variables was carried out and infected and uninfectedpatients were compared.Results. We screened a total of 68 patients who had received rituximab (median cumulative dose: 4,161mg (2,611–8,187.5)). 54.4% men, mean age 60.8 years (15.7; 25-87)). C +was confirmed for 22 patients. Of these, 45.5% had high bloodpressure, 36.4% Diabetes Mellitus, 31.8% smokers/ex-smoker,22.7% lung disease, 13.6% heart disease and 4.5% obesity.There were no statistically significant differences between C+and C-. Only 2 patients developed immunity. For 10 patients(45.5%) did not have a negative CRP until the end of the follow-up. There was no association with cumulative dose ofrituximab. The mortality rate was 22.7% in the C+.Conclusions. We observe that the persistence of the infection leads to a worse evolution of COVID-19. The use of alternatives should be considered during the pandemic, becauseof patients with decreased B-cell function may have high riskof fatal progression from COVID-19. (AU)
