Role of community engagement in advancing vaccine equity.

The COVID-19 pandemic exacerbated existing health disparities among historically and currently underserved, underresourced, and marginalized communities worldwide. These communities faced disproportionate COVID-19 morbidity and mortality and were generally less likely to receive a COVID-19 vaccine once it became widely available to the public. Community engagement is an approach that can help bridge these inequities. This community case study adapted and implemented an existing community engagement framework to tailor a statewide vaccine equity effort that addresses community-specific priorities during a public health emergency. The adapted framework includes the following key phases: (1) creating an environment for community engagement; (2) making the work relevant; (3) narrowing the focus; (4) planning and conducting the work; and (5) evaluating the work. All of these supported the successful establishment of a statewide collaboration that consisted of various partners from various sectors who shared a collective commitment to increase COVID-19 vaccine confidence and address barriers to vaccination among the diverse communities in Nevada. Ultimately, a community engagement framework can provide a roadmap to navigate the dynamic and multifaceted nature of equity-related work by paving the way for meaningful interventions to mitigate health disparities.

Influence of Academic Training and Professional Experience on the Management of Deep Caries Lesions.

BACKGROUND/OBJECTIVES: Managing caries lesions that affect the inner third of the dentin is crucial to ensuring pulp vitality; the clinician must make decisions that will affect the vitality of the tooth. Our purpose is to understand the behavior of Spanish dentists in treating deep cavities and to examine whether variations exist based on their academic training and/or years of professional experience. METHODS: This study was approved by the ethics committee of the Balearic Islands CEI-IB. A survey was conducted using the SurveyMonkey platform with 11 questions, the first 4 of which focused on defining the characteristics of the respondents. The following six concerned a clinical case of deep caries in tooth number 4.7, and the last regarded the opinion of the actual treatment of the case. The survey was sent by email in April 2022. The results were analyzed with the SPSS 29.0 program using the chi-square test. RESULTS: A total of 347 responses were obtained (93.95%), and those surveyed stated that they apply minimal intervention concepts in their treatments, with 90.49% performing conservative dentistry treatments daily. A total of 56.48% of the respondents had bachelor's degrees, 12.39% had graduated, 33.14% had a postgraduate degree, 38.90% had a master's degree, and 17% had a doctorate. Most (40.63%) had been in professional practice for 16-30 years. CONCLUSIONS: Significant differences were identified regarding years of professional experience in terms of decision-making in methods of treatment and the choice of materials used for pulp protection. Likewise, significant differences were found regarding the academic training of the respondents, the cavity cleaning method selected, and the use of chemical substances for removing carious dentin. We can conclude that academic training and years of professional practice influence decision-making at some points in treating deep caries lesions.

Surgical Management of Complex Multiligament Knee Injury: Case Report.

Multiligament knee injuries (MLKIs) frequently require immediate intervention to prevent severe complications, including vascular injury. We present the case of a 51-year-old male who sustained a traumatic right knee dislocation following a motor vehicle accident. The patient exhibited significant tibiofemoral dissociation with Grade 3 instability, classified as Schenck KD IV. Immediate reduction and external fixation were performed, followed by definitive surgical management, which included fibular sling, MPFL and MCL repair, and double-bundle and double-tunnel ACL and PCL reconstruction with looped proximal tibial fixation. The patient showed an excellent early postoperative outcome, with minimal edema, manageable moderate pain, and a full range of motion by the 30-day follow-up. This case underscores the effectiveness of combining fibular sling, MPFL, and MCL, with anatomical double-bundle ACL and PCL reconstruction in the treatment of complex MLKIs. The level of evidence is IV.

Pilot feasibility randomised controlled trial of cognitive-behavioural therapy for functional cognitive disorder after concussion.

Background: Functional cognitive disorder (FCD) may be common after a concussion, and no evidence-based treatment options are available. The current study evaluated the feasibility of a novel cognitive-behavioural therapy (CBT) protocol tailored to FCD after concussion. Methods: Participants were randomised to CBT (n=11) or the current standard of care, cognitive rehabilitation (n=13). Both interventions consisted of eleven 50 min manualised videoconference sessions. CBT involved cognitive reappraisal and exposure-based strategies. Cognitive rehabilitation involved traditional memory compensation strategy training. Prespecified feasibility criteria were set for recruitment, perceived credibility, patient adherence, therapist protocol compliance and retention. The primary efficacy outcome was the Multifactorial Memory Questionnaire-Satisfaction (MMQ-S). The first five CBT completers completed a semistructured interview about their experience with the intervention. Results: Most feasibility benchmarks were met, as 86% of invited patients consented, 96% of participants rated their intervention as credible, participants attended 96% of sessions, therapists covered all essential content in 94% of sessions and 100% of participants completed the post-treatment evaluation. Both groups improved on the MMQ-S. Post-treatment MMQ-S scores were similar between groups (Cohen's d=-0.05 (95% CI [-0.86, 0.75])). Two themes resulted from the qualitative data analysis, which highlighted aspects of the CBT interventions that participants valued. Implications: This pilot trial supports the feasibility of CBT tailored to FCD after concussion and suggests that patients with FCD may benefit from either CBT or standard cognitive rehabilitation. A larger trial is needed to evaluate the efficacy of these interventions for FCD after concussion and potentially FCD in other clinical contexts. Trial registration number: NCT05581810.

Unseen threat: how subclinical atherosclerosis increases mortality risk in patients with type 1 diabetes.

BACKGROUND: Cardiovascular disease (CVD), particularly ischemic heart disease, remains the leading cause of death and morbidity in patients with type 1 diabetes. Detecting subclinical atherosclerosis could enhance cardiovascular risk stratification and enable individualised therapies. The aim of this study is to investigate the prevalence and predictors of subclinical atherosclerosis in patients with type 1 diabetes without overt cardiovascular disease (CVD) and to assess its impact on patient survival over a follow-up period of at least 5 years. METHODS: This observational study included 507 patients treated at the Diabetes Unit of the Hospital of Girona Doctor Josep Trueta between 2015 and 2023. The inclusion criteria for patients were as follows: those aged 18 and older with diabetes for a minimum of 10 years or those aged 40 and older with a diabetes for at least 5 years. Subclinical atherosclerosis was identified via ultrasound imaging of the carotid and femoral arteries. Clinical and biochemical evaluations were also conducted. Major cardiovascular events (MACE) and deaths from other causes were monitored, and survival analysis was performed using Kaplan‒Meier methods. RESULTS: Subclinical atherosclerosis was detected in 218 patients (43%). Multivariate analysis revealed that the male sex, diabetic nephropathy, tobacco exposure, higher HbA1c levels, older age, and longer diabetes duration were significant predictors. During a mean follow-up of 70.64 ± 27.08 months, 19 patients experienced MACE, and 13 died from any cause. The probability of MACE or death was greater in patients with subclinical atherosclerosis, with a hazard ratio (HR) of 25.1 (95% CI 5.81-108, p < 0.001) for MACE and an odds ratio (OR) of 7.57 (95% CI 1.97-53.9, p = 0.004) for death. CONCLUSION: Subclinical atherosclerosis is independently associated with increased overall mortality and MACE in patients with type 1 diabetes. Identifying clinical predictors can improve risk stratification and personalised therapeutic strategies to prevent MACEs in this high-risk population.

Cantharidin (1%), podophyllin (5%), and salicylic acid (30%) formulation in recalcitrant plantar warts: Analysis of 48 patients.

A plantar wart is a benign hyperplasia that appears on the feet due to the human papillomavirus (HPV). One method used for the treatment of recalcitrant plantar warts, those lasting over 2 years or persisting after at least two treatment attempts, is the cantharidin (1%), podophyllin (5%), and salicylic acid (30%) formulation, also known as the CPS formulation. Although this method is in use, there are few studies on it. This study's objective was to ascertain its cure rate. For this retrospective observational study, we reviewed the medical records of patients treated with the CPS formulation at a podiatric clinic specializing in plantar wart treatment. Our sample size was 48 subjects. The CPS formulation had a cure rate of 62.5%. Out of the cured patients, 86.67% (26/30) required one or two applications. There was no observable correlation (p > 0.05) between wart resolution and virus biotype, evolution time, patient's morphological and clinical attributes, location, number of warts, or preceding treatments. The CPS formulation presents a relatively high efficacy rate for treating recalcitrant HPV plantar warts. Still, additional studies are necessary to evaluate its safety and efficiency.

Hydroxychloroquine-induced cardiomyopathy: role of cardiac magnetic resonance for the diagnosis and follow-up of a very rare entity-a case report.

Background: Hydroxychloroquine (HCQ) is a disease-modifying antirheumatic used in rheumatological diseases such as systemic lupus erythematosus. Long-term exposure to HCQ results in drug accumulation and predisposes to adverse effects. Case summary: We present the case of a 45-year-old woman with long-term treatment with HCQ who presented to the Emergency Department with acute heart failure. Transthoracic echocardiogram, previously normal, showed severe biventricular hypertrophy and biventricular systolic dysfunction. Cardiac magnetic resonance (CMR) confirmed the previous findings and showed elevated native T1 and T2 values, elevated extracellular volume, and extensive mid-wall late gadolinium enhancement (LGE). Infiltrative cardiomyopathy was suspected, and endomyocardial biopsy performed. Light microscopy showed myocyte hypertrophy and vacuolar change and absence of lymphocytic inflammatory infiltrates. The diagnosis of HCQ-induced cardiomyopathy was established, and the drug was withdrawn. A CMR performed 1 year later showed normal systolic function of both ventricles and normalization of T2 values, reflecting resolution of myocardial oedema. However, severe hypertrophy, elevated native T1 values, and LGE persisted. Discussion: Our case shows that although discontinuation of the drug stops the progression of the disease, established myocardial structural damage persists. Early diagnosis of this entity is therefore essential to improve prognosis.

Diagnostic Accuracy of Dermatoscopy Versus Microbiological Culture and Polymerase Chain Reaction in the Diagnosis of Onychomycosis: A Cross-Sectional Study.

BACKGROUND: Several clinical signs in dermatoscopy are very characteristic of onychomycosis and can be a quick complement for the diagnosis of onychomycosis. OBJECTIVES: The aim of this study was to evaluate the diagnostic accuracy of dermatoscopy compared to microbiological culture and polymerase chain reaction (PCR), as well as the clinical signs associated with onychomycosis. METHODS: The clinical signs of 125 patients were assessed cross-sectionally using dermatoscopy, and a positive or negative result was assigned. A sample was then taken for PCR and microbiological culture. RESULTS: Of the 125 patients, 69.6% (87/125) had positive results when both laboratory tests were combined. When they were not combined, the prevalence was lower at 48% (60/125) with PCR and at 43.2% (54/125) with culture. Furthermore, 76.8% (96/125) were classified as positive with dermatoscopy with a sensitivity of 1, a specificity of 0.76, positive predictive value of 0.91 and negative predictive value of 1 (with 95% confidence intervals). Of the 96 dermatoscopy-positive samples, 36 were negative with PCR (p < 0.001), 42 were negative with culture (p < 0.001) and nine were negative when both tests were combined (p < 0.001). Clinical signs that were significantly associated with the presence of onychomycosis were subungual hyperkeratosis (dermatoscopy: p = 0.004, odds ratio (OR) = 2.438; PCR + microbiological culture: p = 0.004, OR = 3.221), subungual detritus (p = 0.033, OR = 3.01, only with dermatoscopy) and dermatophytoma (dermatoscopy: p = 0.049, OR = 3.02; PCR + microbiological culture: p = 0.022, OR = 2.40). CONCLUSIONS: The results suggest that dermatoscopy is a good tool for the diagnosis of onychomycosis but should be used as a complementary test or for screening patients to be sampled for laboratory testing. The combination of the three tests can lead to a reduction of false-positive and false-negative clinical and laboratory results. This allows for early diagnosis and specific treatment based on test results.

A novel application of lemmatize and thematic analysis to understand protective measures perspectives of patients with chronic respiratory disease during the first outbreak of COVID-19 pandemic: a qualitative study.

Objective: To describe the perspectives of a group of COPD patients during the first outbreak of the COVID-19 pandemic and narrate the emotions and polarity (acceptance-rejection) regarding living with COPD during the pandemic. Design/methods: We used a novel application of lemmatization and thematic analysis of participants' narratives. A study was carried out with eight patients with moderate-severe-very severe COPD during the first outbreak of COVID-19 using purposive sampling. In-depth interviews and field notes from the researchers were used to collect data. A statistical content analysis (lemmatization) of the patients' narratives was performed. Additionally, inductive thematic analysis was used to identify emerging themes. This study was conducted following the guidelines of Consolidated Criteria/Standards for Reporting Qualitative Research. The study was conducted in accordance with the principles articulated in the WMA Declaration of Helsinki. Participants provided verbal informed consent prior to their inclusion as previously described. Results: The average age of our sample was 65 years, and 75% of the patients suffered from moderate COPD, 12.5% from severe COPD, and 12.5% from very severe COPD according to GOLD criteria. The lemmatized and sentiment analysis showed a predominance of positive emotions, and the polarity of the interviews indicated a very slight positive trend towards acceptance of the experience lived during the pandemic. Additionally, three main themes were identified: (1) Confinement and restriction measures, (2) COVID-19 and protective measures, and (3) Clinical care during the first outbreak of the pandemic. Conclusion: Patients experienced confinement with a feeling of security and protection. They strictly respect social distancing. They used masks, but these caused them to feel short of breath and fatigue, especially FFP2 masks. Half of the patients rejected the possibility of being vaccinated. Finally, they were very satisfied with the clinical care they received in the COPD unit of their hospital. Our results show that COPD patients have not experienced a negative impact of the COVID-19 pandemic.

The Role of Cardiac Magnetic Resonance in mRNA COVID-19 Vaccine-Related Myopericarditis: An Evolutive Case Series.

Numerous cases of myocarditis related to mRNA vaccines for COVID-19 have recently been described, usually in young men. Long-term evolutive cardiac magnetic resonance imaging (CMR) data are lacking. We describe four consecutive cases of COVID-19 vaccine-induced myocarditis. The pathological findings of cardiac magnetic resonance confirmed the diagnosis in the acute phase, showing edema, as well as pericardial enhancement, with light pericardial effusion and late gadolinium enhancement (LGE), predominantly in the inferolateral wall. These cases highlight the unique value of cardiac magnetic resonance in patients with suspected myocarditis induced by COVID-19 RNAm vaccines as a tool to confirm the diagnosis, avoiding other invasive techniques, as well as for the long-term follow-up of patients. Our iterative CMR imaging demonstrated frequent long-term LGE persistence.

Cefiderocol as rescue therapy in a cancer immunosuppressed critically ill child: Case description and literature review.

Severe infections caused by multidrug-resistant bacteria have underscored the urgent need for innovative treatment approaches. Novel antimicrobials like cefiderocol have emerged as effective options, but their use in children remains largely unexplored. In this brief report, we describe a severe case of sepsis in a child with an oncohematological disease, caused by a highly drug-resistant strain of Klebsiella pneumoniae. The addition of cefiderocol to other therapies resulted in a successful outcome. Additionally, we provide a literature review of previously published cases involving children treated with this new antibiotic. In our patient, cefiderocol was both safe and effective in combating the multidrug-resistant pathogen. However, further research is needed to better define the indications and safety profile of this novel antibiotic.

Multi-model hydrological reference dataset over continental Europe and an African basin.

Although Essential Climate Variables (ECVs) have been widely adopted as important metrics for guiding scientific and policy decisions, the Earth Observation (EO) and Land Surface and Hydrologic Model (LSM/HM) communities have yet to treat terrestrial ECVs in an integrated manner. To develop consistent terrestrial ECVs at regional and continental scales, greater collaboration between EO and LSM/HM communities is needed. An essential first step is assessing the LSM/HM simulation uncertainty. To that end, we introduce a new hydrological reference dataset that comprises a range of 19 existing LSM/HM simulations that represent the current state-of-the-art of our LSM/HMs. Simulations are provided on a daily time step, covering Europe, notably the Rhine and Po river basins, alongside the Tugela river basin in Africa, and are uniformly formatted to allow comparisons across simulations. Furthermore, simulations are comprehensively validated with discharge, evapotranspiration, soil moisture and total water storage anomaly observations. Our dataset provides valuable information to support policy development and serves as a benchmark for generating consistent terrestrial ECVs through the integration of EO products.

The Circulating miR-107 as a Potential Biomarker Up-Regulated in Castration-Resistant Prostate Cancer.

Prostate cancer (PCa) is a prevalent malignancy in men globally. Current diagnostic methods like PSA testing have limitations, leading to overdiagnosis and unnecessary treatment. Castration-resistant prostate cancer (CRPC) emerges in some patients receiving androgen deprivation therapy (ADT). This study explores the potential of circulating microRNA-107 (miR-107) in liquid biopsies as a prognosis tool to differentiate CRPC from non-castration-resistant PCa (NCRPC). We designed a case-control study to evaluate circulating miR-107 in serum as a potential prognosis biomarker. We analyzed miR-107 expression in liquid biopsies and found significantly higher levels (p < 0.005) in CRPC patients, compared to NCRPC. Notably, miR-107 expression was statistically higher in the advanced stage (clinical stage IV), compared to stages I-III. Furthermore, CRPC patients exhibited significantly higher miR-107 levels (p < 0.05), compared to NCRPC. These findings suggest that miR-107 holds promise as a non-invasive diagnostic biomarker for identifying potential CRPC patients.

Agreement between two cephalometric analyses of facial growth direction and biotype / Concordancia entre dos análisis cefalométricos de dirección de crecimiento y biotipo facial

Abstract Cephalometry is a morphological and descriptive diagnostic method that provides relevant data on skeletal and dentoalveolar malocclusions of patients seeking orthodontics treatment. Several authors have proposed different cephalometric measurements to determine facial growth direction and facial biotype, the results of these different measurements from the same patient do not always agree on the diagnosis. The aim of this study was to determine the level of agreement between Ricketts and Björk-Jarabak cephalometric analyses for the determination of facial growth direction and facial biotype in patients from a population of Yucatan, Mexico. A total of 260 lateral cephalograms of patients between 18 and 59 years of age were digitally traced using the Ricketts and Björk-Jarabak cephalometric analyses to determine the direction of facial growth and facial biotype using Dolphin Imagine software. Cohen's kappa statistical test was performed to establish the strength of agreement between the diagnostic results obtained by the cephalometric analyses. A poor diagnostic concordance strength was found for growth direction (K=0.105), and acceptable for facial biotype (K=0.362). The concordance strengths for each diagnostic possibility (level) ranged from slight to acceptable, except for the brachyfacial and dolichofacial biotypes, with a moderate strength of agreement. In conclusion, the Ricketts and Björk- Jarabak cephalometric measurements used for the determination of facial biotype and facial growth direction could suggest non-concordant diagnostic assessments in some individuals.

Resumen La cefalometría es un método diagnóstico morfológico y descriptivo que proporciona datos relevantes sobre maloclusiones esqueléticas y dentoalveolares de pacientes que buscan tratamiento de ortodoncia. Varios autores han propuesto diferentes mediciones cefalométricas para determinar la dirección del crecimiento facial y el biotipo facial, los resultados de estas diferentes mediciones de un mismo paciente no siempre coinciden en el diagnóstico. El objetivo de este estudio fue determinar el nivel de concordancia entre los análisis cefalométricos de Ricketts y Björk-Jarabak para la determinación de la dirección del crecimiento facial y el biotipo facial en pacientes de una población de Yucatán, México. Se trazaron digitalmente un total de 260 cefalogramas laterales de pacientes entre 18 y 59 años de edad utilizando los análisis cefalométricos de Ricketts y Björk-Jarabak para determinar la dirección del crecimiento facial y el biotipo facial utilizando el software Dolphin Imagine. Se realizó la prueba estadística kappa de Cohen para establecer la fuerza de concordancia entre los resultados diagnósticos obtenidos por los análisis cefalométricos. Se encontró una fuerza de concordancia diagnóstica deficiente para la dirección del crecimiento (K=0.105) y aceptable para el biotipo facial (K=0.362). Los niveles de concordancia para cada posibilidad diagnóstica (nivel) variaron de leve a aceptable, excepto para los biotipos braquifacial y dolicofacial, con un nivel de concordancia moderado. En conclusión, las mediciones cefalométricas de Ricketts y Björk-Jarabak utilizadas para la determinación del biotipo facial y la dirección del crecimiento facial podrían sugerir evaluaciones diagnósticas no concordantes en algunos individuos.

The intestinal microbiome of infants with cow's milk-induced FPIES is enriched in taxa and genes of enterobacteria.

OBJECTIVES: Food protein-induced enterocolitis syndrome (FPIES) is a severe type of non-IgE (immunoglobulin E)-mediated (NIM) food allergy, with cow's milk (CM) being the most common offending food. The relationship between the gut microbiota and its metabolites with the inflammatory process in infants with CM FPIES is unknown, although evidence suggests a microbial dysbiosis in NIM patients. This study was performed to contribute to the knowledge of the interaction between the gut microbiota and its derived metabolites with the local immune system in feces of infants with CM FPIES at diagnosis. METHODS: Twelve infants with CM FPIES and a matched healthy control group were recruited and the gut microbiota was investigated by 16S amplicon and shotgun sequencing. Fatty acids (FAs) were measured by gas chromatography, while immune factors were determined by enzyme-linked immunosorbent assay and Luminex technology. RESULTS: A specific pattern of microbiota in the gut of CM FPIES patients was found, characterized by a high abundance of enterobacteria. Also, an intense excretion of FAs in the feces of these infants was observed. Furthermore, correlations were found between fecal bifidobacteria and immune factors. CONCLUSION: These fecal determinations may be useful to gain insight into the pathophysiology of this syndrome and should be taken in consideration for future studies of FPIES patients.

Engineering synthetic agonists for targeted activation of Notch signaling.

Notch signaling regulates cell fate decisions and has context-dependent tumorigenic or tumor suppressor functions. Although there are several classes of Notch inhibitors, the mechanical force requirement for Notch receptor activation has hindered attempts to generate soluble agonists. To address this problem, we engineered synthetic Notch agonist (SNAG) proteins by tethering affinity-matured Notch ligands to antibodies or cytokines that internalize their targets. This bispecific format enables SNAGs to "pull" on mechanosensitive Notch receptors, triggering their activation in the presence of a desired biomarker. We successfully developed SNAGs targeting six independent surface markers, including the tumor antigens PDL1, CD19, and HER2, and the immunostimulatory receptor CD40. SNAGs targeting CD40 increase expansion of central memory γδ T cells from peripheral blood, highlighting their potential to improve the phenotype and yield of low-abundance T cell subsets. These insights have broad implications for the pharmacological activation of mechanoreceptors and will expand our ability to modulate Notch signaling in biotechnology.

Long Term Follow-Up Observation in Small Choroidal Melanocytic Tumors.

BACKGROUND: The purpose of this study is to analyze the long-term evolution of patients with small choroidal melanocytic tumors (SCMTs) undergoing observation, and to assess their rate of transformation into melanomas and survival. METHODS: A retrospective single-cohort study of patients with SCMTs (1-3 mm in height and 5-10 mm in base) diagnosed from January 1992 to February 2023 was carried out, with observation as the initial treatment. The main criterion for a transformation into melanoma is considered to be an increase in size of more than 1 mm in height and/or more than 1 mm in base measured on an ultrasound/retinography, recorded in two consecutive visits separated by one to three months. RESULTS: 243 patients were included with a mean age of 65.3 years and a mean follow-up of 7.9 years (6 months-27.9 years); 27 patients showed tumor growth. The probabilities of growth at 5, 10, and 15 years are 10%, 14%, and 17%, respectively. Regarding survival, 22 patients died and only 3 deaths were due to melanoma metastasis. Survival rates at 5 and 10 years are 99% and 97%. CONCLUSIONS: Observation is a viable therapeutic option for SCMTs, avoiding the side effects of treatment, considering the majority of these tumors do not progress to melanoma. With close monitoring, patients can be treated promptly upon detecting a transformation. Additionally, the findings confirm that small melanocytic tumors can lead to metastatic disease, albeit at a low rate.

Community-Based Interventions in People with Palliative Care Needs: An Integrative Review of Studies from 2017 to 2022.

AIM: To describe the latest scientific evidence regarding community-based interventions performed on patients in need of palliative care worldwide. INTRODUCTION AND BACKGROUND: Given the rise of chronic diseases, their complexities and the fragility of patients, we are facing around 56.8 million people in need of palliative care. Community-based healthcare, particularly palliative care, can address social inequalities and improve the biopsychosocial health of disadvantaged populations. Therefore, primary care, as the main health referent in the community, has a central role in the care of these patients. METHODS: This is an integrative review from January 2017 to June 2022 that follows the PRISMA statement and has been registered in PROSPERO. PubMed, Cuiden, the Web of Science (WoS), Cochrane and LILACS were the five databases searched. The scientific quality assessment of the articles was carried out following the CASPe methodology. Study selection was carried out by two researchers, A.V.L. and J.M.C.T., using the inclusion and exclusion criteria mentioned below. In cases of doubt or discrepancy, a third author (J.R.S.) was consulted. RESULTS: The interventions mentioned in the 16 articles analysed were classified under the following categories: music therapy, laughter therapy, spiritual and cognitive interventions, aromatherapy, interdisciplinary and community-based teams, advance care planning and community, volunteering, telemedicine and care mapping. EXAMPLE: Educating people to talk about different ethical issues could improve their quality of life and help develop more compassionate cities. CONCLUSIONS: We have identified interventions that are easily accessible (laughter therapy, telemedicine or music therapy), simple enough to be carried out at the community level and do not incur high costs. This is why they are recommended for people with palliative care needs in order to improve their quality of life.

Dense Hydrated Magnesium Carbonate MgCO3·3H2O Phases.

The study of the structural stability of carbonates under different pressure and temperature conditions is important for modeling the carbon budget in the Earth's interior and the stability of carbonation products of carbon capture and storage (CCS) solutions. In this work, we confirm the existence of the two dense polymorphs of the hydrated magnesium carbonate MgCO3·3H2O nesquehonite mineral previously reported, and we characterize their structures using synchrotron single-crystal X-ray diffraction at 3.1 and 11.6 GPa. Phase transitions entail the distortion and atomic rearrangement of the Mg-centered polyhedra and the tilting of the [CO3] carbonate units. In particular, the Mg coordination number increases from 6 in nesquehonite to 7 in the second high-pressure phase, while maintaining a topology based on complex MgCO3(H2O)2 chains. We also studied their vibrational behavior upon compression using Raman spectroscopy and complemented the experimental results with density-functional theory (DFT) calculations. The role played by hydrogen bonds in the compressibility and the polymorphism of this hydrated carbonate is also discussed.

Atrial Imaging and Cardiac Rhythm in Cryptogenic Embolic Stroke: The ARIES Study.

BACKGROUND: Unknown cardioembolic sources are frequent causes of cryptogenic stroke. We analyzed the risk of atrial fibrillation (AF) or high burden of ectopic atrial activity (HBEA) in patients with cryptogenic stroke, assessing atrial function and 1-year outcomes. METHODS AND RESULTS: The ARIES (Atrial Imaging and Cardiac Rhythm in Cryptogenic Embolic Stroke) study is an observational study including patients with cryptogenic stroke. We analyzed the frequency of AF and HBEA (>3000 atrial ectopic beats/day or >2 bursts or atrial tachycardia between 3 beats and ≤30 seconds) in two 30-day Holter-ECGs, comparing advanced echocardiography signs of left atrial (LA) dysfunction according to rhythm: AF, HBEA, and normal sinus rhythm. We also evaluated 1-year stroke recurrence and mortality. The study included 109 patients; 35 (32.1%) patients had AF, 27 (24.8%) HBEA, and 47 (43.1%) normal sinus rhythm. Compared with those with normal sinus rhythm, patients with AF presented higher 2-dimensional and 3-dimensional LA indexed volumes (38.8±11.2 versus 27.3±11.8 mL/m2, and 50.6±17.2 versus 34.0±15.4 mL/m2, respectively, P<0.001), lower 3-dimensional LA ejection fraction (50±14.6 versus 62.7±11.8, P=0.001), LA reservoir strain (22.0±8.6 versus 30.4±10.5, P<0.001), and LA contraction strain (10.5±8.18 versus 17.1±7.5, P<0.001), remaining significant in multivariate analysis. Patients with HBEA showed higher LA indexed volumes and lower LA reservoir strain than patients with normal sinus rhythm only in univariate analysis. There were no differences in ischemic recurrence or mortality among the groups. CONCLUSIONS: Patients with cryptogenic stroke showed a high incidence of AF and HBEA. AF is strongly related to LA volume, LA function, and LA reservoir and contraction strain, whereas HBEA showed milder structural changes. Advanced LA echocardiography could help patient selection for long-term ECG monitoring in suspected cardiac sources.
