Evolution of the impact of the COVID-19 pandemic on heart transplant recipients: Decreasing risk, improving perspective.

BACKGROUND AND METHODS: Heart transplant recipients (HTr) have a higher probability of suffer from severe coronavirus disease-2019 (COVID-19) in comparison to general population, but their risk has changed over the course of the pandemic in relation to various factors. We conducted a prospective study including all HTr at risk of COVID-19 in a tertiary center between February 2020 and October 2022. The aim was to analyze how the prognosis (incidence of pneumonia and mortality) of COVID-19 in HTr has evolved over time, contextualizing variants, vaccination, and other treatments. RESULTS: Of 308 HTr included, 124 got the infection (39.2%). COVID and non-COVID HTr had similar baseline characteristics. COVID-19 patients with pneumonia had a poorer prognosis than those with less severe presentations, with a higher rate of hospitalization (93.3 vs. 14.1%, p < .001) and death (41.0 vs. 1.2%, p < .001). Multivariate analysis identified age ≥60 years (odds ratio [OR] 3.65, 95% confidence interval [CI] 1.16-11.49, p = .027), and chronic kidney disease ≥3a (OR 4.95, 95% CI 1.39-17.54, p = .014) as predictors of pneumonia. Two-dose vaccination (OR 0.20, CI 95% 0.05-0.72, p = .02) and early remdesivir administration (OR 0.17, CI 0.03-0.90, p = .037) were protective factors. Over the course of the pandemic considering three periods in the follow-up (prevaccination February-December 2020, postvaccination January-December 2021, and post early remdesivir indication January-October 2022), we observed a reduction in pneumonia incidence from 62% to 19% (p < .001); and mortality (from 23% to 4%, p < .001). CONCLUSIONS: The prognosis of COVID-19 in HTr has improved over time, likely due to vaccination and early administration of remdesivir.

The perception of healthcare professionals, through their own personal experiences, of the use of music therapy in hospitalised children and adolescents.

BACKGROUND: Music therapy is an emerging and useful methodology for improving patient environments within healthcare fields. However, although it has been shown that music therapy interventions with hospitalised children and adolescents have been used for decades with positive effects, there are currently very few studies that specifically describe the perspectives of healthcare professionals regarding the value of music therapy when applied in these patients. OBJECTIVES: To describe the insights of healthcare professionals regarding music therapy, both on a personal level and in terms of its usefulness in the care of hospitalised children and adolescents. DESIGN: This was a qualitative descriptive-exploratory study with focus groups. PARTICIPANTS: Eighteen healthcare professionals. METHODS: In January 2023, two focus groups, containing nine healthcare professionals each, were created to collect data regarding their experiences concerning the effect of music therapy on hospitalised children and adolescents. Before recording their opinions, all these professionals participated in an interactive music therapy session. The thematic analysis in this work was performed using MAXQDA® software. RESULTS: Two main categories emerged: (a) the effects of music therapy on healthcare professionals, and (b) the benefits of music therapy to patients (children and adolescents). CONCLUSIONS: Music therapy was valued positively by healthcare professionals who described the benefits its use has for hospitalised children and adolescents. They also expressed positive viewpoints regarding the use of music therapy to improve their own self-knowledge and self-care. IMPLICATIONS TO PRACTICE: Healthcare professionals may utilise music therapists to improve patient outcomes and reduce the negative effects of hospitalisation.

The Role of Cell Cycle Arrest Biomarkers for Predicting Acute Kidney Injury in Critically Ill COVID-19 Patients: A Multicenter, Observational Study.

OBJECTIVES: Patients with COVID-19-associated acute respiratory distress syndrome (ARDS) have a high risk for developing acute kidney injury (AKI) which is associated with an increased risk of death and persistent renal failure. Early prediction of AKI is crucial in order to implement preventive strategies. The purpose of this study was to investigate the predictive performance of tissue inhibitor of metalloproteinases 2 and insulin like growth factor binding protein 7 (TIMP-2) × (IGFBP7) in critically ill patients with COVID-19-associated ARDS. DESIGN: Multicenter, prospective, observational study. SETTING: Twelve centers across Europe and United Kingdom. PATIENTS: Patients with moderate or severe COVID-19-associated ARDS were included and serial measurements of (TIMP-2) × (IGFBP7) were performed. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary endpoint was the development of moderate or severe AKI according to the Kidney Disease: Improving Global Outcomes definition. Three hundred patients were available for the primary analysis, and 39 met the primary endpoint. At enrollment, urinary (TIMP-2) × (IGFBP7) had high predictive value for the primary endpoint with an area under the receiver operating characteristic curve of 0.89 (95% CI, 0.84-0.93). (TIMP-2) × (IGFBP7) was significantly higher in endpoint-positive patients at enrollment and at 12 hours. CONCLUSIONS: Urinary (TIMP-2) × (IGFBP7) predicts the occurrence of AKI in critically ill patients with COVID-19-associated ARDS.

Perceptions and attitudes of pediatricians and families with regard to pediatric medication errors at home.

PURPOSE: This study aimed to identify the perceptions and attitudes of pediatricians and parents/caregivers regarding medication errors at home, and to compare the findings from the two populations. METHODS: This was a cross-sectional survey study. We designed a survey for working pediatricians and another one for parents or caregivers of children aged 14 years and younger. The survey's questions were designed to assess provider and parental opinions about the difficulty faced by parents providing medical treatment, specific questions on medication errors, and on a possible intervention program aimed at preventing pediatric medication errors. Pediatrician and parent responses to matching questions in both surveys were compared. RESULTS: The surveys were administered in Spain from 2019 to 2021. In total, 182 pediatricians and 194 families took part. Most pediatricians (62.6%) and families (79.3%) considered that managing medical treatment was not among the main difficulties faced by parents in caring for their children. While 79.1% of pediatricians thought that parents consulted the internet to resolve doubts regarding the health of their children, most families (81.1%) said they consulted healthcare professionals. Lack of knowledge among parents and caregivers was one of the causes of medication errors most frequently mentioned by both pediatricians and parents. Most pediatricians (95.1%) said they would recommend a program designed to prevent errors at home. CONCLUSIONS: Pediatricians and families think that medical treatment is not among the main difficulties faced by parents in caring for their children. Most pediatricians said they would recommend a medication error reporting and learning system designed for families of their patients to prevent medication errors that might occur in the home environment.

Inflammatory myofibroblastic tumor of the lung involving the central nervous system in pediatric patients.

INTRODUCTION: The inflammatory myofibroblastic tumor (IMT) is a very rare lesion with an incidence of less than 0.1% of total neoplasms and with main affection in the lungs. Involvement in the central nervous system is extremely rare, but with a much more aggressive course than IMT diagnosed in the rest of the body. We report the 2 cases presented in our neurosurgery department to date; both were treated satisfactorily without intercurrences in 10 years of follow-up. HISTORICAL BACKGROUND: The World Health Organization described the IMT as a distinctive lesion composed of myofibroblastic spindle cells accompanied by an inflammatory infiltrate of plasma cells, lymphocytes, and eosinophils. CLINICAL PRESENTATION: Clinical manifestations of patients with CNS IMT vary and may consist of headache, vomiting, seizures, and blindness. Seizures are the most common symptom in patients with focal lesions. DIAGNOSIS: The true origin of this entity remains to be elucidated, but to date, etiologies ranging from chromosomal alterations to autoimmune or postinfectious mechanisms have been described. Due to its rarity and non-specificity in imaging, the final diagnosis of IMT in the brain parenchyma relies on pathological examination. MANAGEMENT: Treatment options are controversial and include total or subtotal removal, high-dose steroids, and radiation therapy. In the last decade, the development of ALK Tyrosine Kinase Inhibitors allows the possibility of chemotherapy in those patients harboring ALK mutations. CONCLUSION: IMT is a rare tumor that can exceptionally be found in the CNS. The cause is still unknown although the different studies focus on a neoplastic origin. The diagnosis is based in the use of different modalities of imaging and with histological confirmation. Optimal management is gross total resection whenever possible, is the only established curative treatment. Further research with longer follow-up is needed to clarify the natural history of this rare tumor.

Work-from-home is here to stay: Call for flexibility in post-pandemic work policies.

In early 2020, the Covid-19 pandemic forced employees in tech companies worldwide to abruptly transition from working in offices to working from their homes. During two years of predominantly working from home, employees and managers alike formed expectations about what post-pandemic working life should look like. Many companies are experimenting with new work policies that balance employee- and manager expectations regarding where, when and how work should be done in the future. In this article, we gather experiences of the new trend of remote working based on the synthesis of 22 company-internal surveys of employee preferences for WFH, and 26 post-pandemic work policies from 17 companies and their sites, covering 12 countries in total. Our results are threefold. First, through the new work policies, all companies formally give employees more flexibility regarding working time and location. Second, there is a great variation in how much flexibility the companies are willing to yield to the employees. The paper details the different formulations that companies adopted to document the extent of permitted WFH, exceptions, relocation permits and the authorisation procedures. Third, we document a change in the psychological contract between employees and managers, where the option of working from home is converted from an exclusive perk that managers could choose to give to the few, to a core privilege that all employees feel they are entitled to. Finally, there are indications that as the companies learn and solicit feedback regarding the efficiency of the chosen strategies, we will see further developments and changes in the work policies concerning how much flexibility to work whenever and from wherever they grant. Through these findings, the paper contributes to a growing literature about the new trends emerging from the pandemic in tech companies and spells out practical implications onwards.

Athlete Heart in Children and Young Athletes. Echocardiographic Findings in 331 Cases.

The changes of the athlete's heart are not well defined and characterized in children. We aimed to describe the morphological changes of the heart related to sport in young athletes. We evaluated a group of 331 young athletes under 18 years (mean 11.9 ± 3.2) who practice tennis: 58 (16.52%), football: 118 (33.62%), basketball: 16 (4.56%), athletics: 40 (11.4%), and swimming: 99 (28.21%). Type of sport, years of practice, and duration of the training were collected. All children underwent echocardiography with the following M-mode parameters: left atrium diameter (LAD), interventricular septum (IVS), and left ventricle posterior Wall (LVPW), diastolic diameter of the left ventricle (LVDD), and right ventricle outflow tract (RVOT). The major finding of our study was that 20% of the children had a Z score > 2 for the IVS and that increased to 30% for the children playing tennis or swimming. Also, other changes like LA and RVOT dilatation were observed in about 10 and 14% of the cases, respectively. Taken together, these figures indicate that cardiac remodeling is frequent in children. Further studies are needed to establish consensus-based criteria of athlete's heart in young children.

Cu(I)-I-2,4-diaminopyrimidine Coordination Polymers with Optoelectronic Properties as a Proof of Concept for Solar Cells.

Two coordination polymers with formulas [CuI(dapym)]n and [Cu2I2(dapym)]n (dapym = 2,4-diaminopyrimidine) have been synthesized in water at room temperature. According to the stoichiometry used, mono (1D) and the two-dimensional (2D) structures can be obtained. Both are made up of Cu2I2 double chains. Their high insolubility in the reaction medium also makes it possible to obtain them on a nanometric scale. Their structural flexibility and short Cu-Cu distances provoke interesting optoelectronic properties and respond to physical stimuli such as pressure and temperature, making them interesting for sensor applications. The experimental and theoretical studies allow us to propose different emission mechanisms with different behaviors despite containing the same organic ligand. These behaviors are attributed to their structural differences. The emission spectra versus pressure and temperature suggest competencies between different transitions, founding critical Cu2I2 environments, i.e., symmetric in the 1D compound and asymmetric for the 2D one. The intensity in the 2D compound's emission increases with decreasing temperature, and this behavior can be rationalized with a structural constriction that decreases the Cu-Cu and Cu-I distances. However, compound 1D exhibits a contrary behavior that may be related to a change of the organic ligand's molecular configuration. These changes imply that a more significant Π-Π interaction counteracts the contraction in distances and angles when the temperature decreased. Also, the experimental conductivity measurements and theoretical calculations show a semiconductor behavior. The absorption of the 1D compound in UV, its intense emission at room temperature, and the reduction to nanometric size have allowed us to combine it homogeneously with ethyl vinyl acetate (EVA), creating a new composite material. The external quantum efficiency of this material in a Si photovoltaic mini-module has shown that this compound is an active species with application in solar cells since it can move the photons of the incident radiation (UV region) to longer wavelengths.

ECCO2R therapy in the ICU: consensus of a European round table meeting.

BACKGROUND: With recent advances in technology, patients with acute respiratory distress syndrome (ARDS) and severe acute exacerbations of chronic obstructive pulmonary disease (ae-COPD) could benefit from extracorporeal CO2 removal (ECCO2R). However, current evidence in these indications is limited. A European ECCO2R Expert Round Table Meeting was convened to further explore the potential for this treatment approach. METHODS: A modified Delphi-based method was used to collate European experts' views to better understand how ECCO2R therapy is applied, identify how patients are selected and how treatment decisions are made, as well as to identify any points of consensus. RESULTS: Fourteen participants were selected based on known clinical expertise in critical care and in providing respiratory support with ECCO2R or extracorporeal membrane oxygenation. ARDS was considered the primary indication for ECCO2R therapy (n = 7), while 3 participants considered ae-COPD the primary indication. The group agreed that the primary treatment goal of ECCO2R therapy in patients with ARDS was to apply ultra-protective lung ventilation via managing CO2 levels. Driving pressure (≥ 14 cmH2O) followed by plateau pressure (Pplat; ≥ 25 cmH2O) was considered the most important criteria for ECCO2R initiation. Key treatment targets for patients with ARDS undergoing ECCO2R included pH (> 7.30), respiratory rate (< 25 or < 20 breaths/min), driving pressure (< 14 cmH2O) and Pplat (< 25 cmH2O). In ae-COPD, there was consensus that, in patients at risk of non-invasive ventilation (NIV) failure, no decrease in PaCO2 and no decrease in respiratory rate were key criteria for initiating ECCO2R therapy. Key treatment targets in ae-COPD were patient comfort, pH (> 7.30-7.35), respiratory rate (< 20-25 breaths/min), decrease of PaCO2 (by 10-20%), weaning from NIV, decrease in HCO3- and maintaining haemodynamic stability. Consensus was reached on weaning protocols for both indications. Anticoagulation with intravenous unfractionated heparin was the strategy preferred by the group. CONCLUSIONS: Insights from this group of experienced physicians suggest that ECCO2R therapy may be an effective supportive treatment for adults with ARDS or ae-COPD. Further evidence from randomised clinical trials and/or high-quality prospective studies is needed to better guide decision making.

Important knowledge for parents of children with heart disease: parent, nurse, and physician views.

OBJECTIVES: Parental understanding of their children's heart disease is inadequate, which may contribute to poor health outcomes. The purpose of this study was to determine what parental knowledge is important in the care of children with heart disease from the perspective of parents, nurses, and physicians. METHODS: Focus groups were formed with parents of children with single ventricle congenital heart disease (CHD), biventricular CHD, and heart transplantation, and with nurses and physicians who provide care for these children. A nominal group technique was used to identify and prioritise important parental knowledge items and themes. The voting data for each theme were reported by participant type--parent, nurse, and physician--and patient diagnosis--single ventricle CHD, biventricular CHD, and heart transplantation. RESULTS: The following three themes were identified as important by all groups: recognition of and response to clinical deterioration, medications, and prognosis and plan. Additional themes that were unique to specific groups included the following: medical team members and interactions (parents), tests and labs (parents), neurodevelopmental outcomes and interventions (physicians), lifelong disease requiring lifelong follow-up (physicians and nurses), and diagnosis, physiology, and interventions (single ventricle and biventricular CHD). CONCLUSIONS: Parents, nurses, and physicians have both common and unique views regarding what parents should know to effectively care for their children with single ventricle CHD, biventricular CHD, or heart transplantation. Specific targeted parental education that incorporates these findings should be provided to each group. Further development of questionnaires regarding parental knowledge with appropriate content validity is warranted.

Case report: Prosthetic aortic valve endocarditis due to Staphylococcus epidermidis with acquired resistance in the walK gene.

We report the case of a patient with infective endocarditis on a prosthetic aortic valve due to Staphylococcus epidermidis, not a candidate for prosthetic replacement surgery. After three months of supressive treatment with dalbavancin, fever reappears, with growth of S. epidermidis. Susceptibility testing showed new-onset resistance to dalbavancin, with a mutation in walK gene.

A cognitive mobile BTS solution with software-defined radioelectric sensing.

Private communications inside large vehicles such as ships may be effectively provided using standard cellular systems. In this paper we propose a new solution based on software-defined radio with electromagnetic sensing support. Software-defined radio allows low-cost developments and, potentially, added-value services not available in commercial cellular networks. The platform of reference, OpenBTS, only supports single-channel cells. Our proposal, however, has the ability of changing BTS channel frequency without disrupting ongoing communications. This ability should be mandatory in vehicular environments, where neighbouring cell configurations may change rapidly, so a moving cell must be reconfigured in real-time to avoid interferences. Full details about frequency occupancy sensing and the channel reselection procedure are provided in this paper. Moreover, a procedure for fast terminal detection is proposed. This may be decisive in emergency situations, e.g., if someone falls overboard. Different tests confirm the feasibility of our proposal and its compatibility with commercial GSM terminals.

Herpes simplex virus colitis mimicking acute severe ulcerative colitis: a case report and review of the literature.

A 60-year-old female patient with longstanding left-sided ulcerative colitis presented with symptoms mimicking an acute flare and developed a colonic perforation shortly after starting steroid treatment. Following left hemicolectomy and Hartmann's procedure, rescue treatment with infliximab was started. Within a few days, the patient developed hepatic failure. Histology and immunohistochemistry of the specimen revealed extensive necrotizing herpes simplex virus colitis, and liver biopsy demonstrated herpes simplex virus hepatitis. Sixteen days after admission, the patient died from multiorgan failure. This compelling case of severe herpes simplex virus colitis raises awareness of a rare but potentially detrimental infection in patients with inflammatory bowel disease.

The Promotion of Mental Health and Prevention of First-Episode Psychosis: A Pilot and Feasibility Non-Randomised Clinical Trial.

BACKGROUND: Mental-health-related stigma prevents active help seeking and therefore early therapeutic approaches and the recovery of functionality. National and international agencies recommend the implementation of prevention and mental health promotion programs that support the elimination of stigma in the classroom, since most mental health problems usually start in the adolescent stage. In view of the evidence that teachers present stigmatizing attitudes towards mental health, it has been considered as convenient to carry out an anti-stigma program with the main objective of evaluating the impact of an intervention based on the education and promotion of mental health, aimed at teachers and counsellors of a secondary school. The specific objectives were to get to know which were the most stigmatising attitudes that prevailed in the sample before and after the intervention; to evaluate the knowledge of the teaching staff and counsellors on psychosis before the intervention; to analyse correlations between clinically relevant variables; and assess whether this programme was beneficial and feasible for alphabetising counsellors/teachers of educational centres on stigma and FEP. METHODS: This was a non-randomised clinical trial in which a nursing intervention was performed. TOOLS: a psychosis test (pre), Stigma Attribution Questionnaire (AQ-27) (pre-post), and satisfaction survey (post) were used. The inferential analysis included the Wilcoxon and the Pearson Correlation Test. RESULTS: In the sample (n = 22), the predominant stigmatising attitude was "Help". The p-values obtained in the Wilcoxon Test were statistically significant, except for "Responsibility" and "Pity". The following constructs of interest were faced: "Fear"-"Age" and "Professional experience"; and "Help"-"Psychosis test". CONCLUSIONS: Despite the scores obtained in "Responsibility" and "Pity", the intervention was useful for reducing stigma in the sample. Implications for the profession: There are adolescents who have suffered stigma from their teachers, and consequently have minimized their symptoms and not asked for help. For this reason, we implemented a nursing intervention based on the education and promotion of mental health, with the aim of expanding knowledge and reducing stigma. In fact, this intervention, which we carried out on high school teachers, managed to reduce the majority of stigmatizing attitudes measured on the stigma attribution scale.

Lung Transplantation for Multiple Giant Hamartomas: First Case Report and Review of the Literature.

BACKGROUND: To assess lung transplant as a solution for a rare complication of giant lung hamartoma, in which surgical resection was discouraged because of severe underlying chronic lung disease. METHODS: A 54-year-old woman had an episode of severe acute hemoptysis. Imaging techniques showed 2 masses in the right lung as hamartomas and severe pulmonary emphysema. After resolution of the acute episode of hemoptysis, the case could have been solved with a right pneumonectomy; however, a single-lung transplant was performed because of the underlying chronic obstructive pulmonary disease. RESULTS: The outcome of the surgery was satisfactory, although a second operation was required because of bleeding. The patient was discharged and currently has a good quality of life, with no recurrence of the disease. The pathologic anatomy of the surgical specimen confirmed the diagnosis of multiple giant hamartomas. CONCLUSIONS: Lung transplant could be a feasible procedure to treat life-threatening complications of benign tumors in selected patients with pulmonary end-stage disease.

Multiloculated hydrocephalus.

OBJECTIVE: The study aims to assess the treatment of progressive multiloculated hydrocephalus. In a retrospective study, the authors reviewed their experience with different treatment modalities. METHODS: We have retrospectively evaluated 93 patients with progressive multiloculated hydrocephalus operated between 1988 and 2010. They represented around 2% (93/4,565) of all patients surgically treated for nontumoral hydrocephalus during this period of time at our institution. RESULTS: Ventricular septal fenestration was carried out by craniotomy in 27 patients, endoscopic septum pellucidum fenestration in 19, endoscopic ventricular septal fenestration in 18, choroid plexectomy-fulguration in 14 (8 endoscopically and 6 by craniotomy), and third ventriculostomy in 2. Hydrocephalus was resolved in 21 patients with shunting, placing two ventricular catheters as the only procedure. Out of the 72 remaining patients, 34 underwent only one treatment, 30 two treatments, and 8 three or more procedures. The majority of patients ultimately required CSF shunt placement with only one ventricular catheter. CONCLUSIONS: (1) Multiloculated hydrocephalus is a severe disease in which no single treatment has clearly been shown to be superior. (2) The goal of treatment is to restore communication between isolated intraventricular compartments in order to create the possibility of the implantation of a simple shunt with only one intraventricular catheter. More than improving the quality of life the patient, the objective is to reduce the number of surgical procedures. (3) Given the complexity of multiloculated hydrocephalus, each patient must be studied individually, and no procedure proposed by the literature should be ruled out, no matter how old fashioned may appear.

Feasibility of a Brief Online Mindfulness and Compassion-Based Intervention to Promote Mental Health Among University Students During the COVID-19 Pandemic.

Objectives: The COVID-19 pandemic constitutes a global mental health challenge that has disrupted the lives of millions of people, with a considerable effect on university students. The aim of this study was to assess the feasibility of a brief online Mindfulness and Compassion-based Intervention to promote mental health among first year university students during COVID-19 home confinement. Methods: Participants (n=66) were first-year psychology students from a university in Spain with no prior meditation experience. Intervention lasted for 16 days and was designed ad-hoc. Using a pre-post within-subjects design, feasibility was assessed in five domains (acceptability, satisfaction, implementation, practicality, and limited efficacy testing). Participants completed both baseline and post-intervention assessments of perceived stress, anxiety, and self-compassion. Results: The intervention showed to be feasible in all domains evaluated. It was implemented as planned with constrained resources, and limited efficacy testing showed promising results. After the intervention, stress and anxiety levels decreased significantly (p<0.001, Hedges's g=0.5146; p<0.001, Hedges's g=0.6068, respectively) whereas self-compassion levels were augmented significantly (p<0.001, Hedges's g=0.6968). Conclusions: Our findings suggest that a brief online mindfulness and compassion intervention may be a feasible way of promoting mental health among university students during COVID-19 lockdown. Further studies are required to address the limitations of the present study. We conclude that online interventions may constitute a promising pathway to buffer the mental health burden derived from the COVID-19 pandemic.
