ABSTRACT

BACKGROUND: From the first steps of prostate cancer (PCa) initiation, tumours are in contact with the most-proximal adipose tissue called periprostatic adipose tissue (PPAT). Extracellular vesicles are important carriers of non-coding RNA such as miRNAs that are crucial for cellular communication. The secretion of extracellular vesicles by PPAT may play a key role in the interactions between adipocytes and tumour. Analysing the PPAT exovesicles (EVs) derived-miRNA content can be of great relevance for understanding tumour progression and aggressiveness. METHODS: A total of 24 samples of human PPAT and 17 samples of perivesical adipose tissue (PVAT) were used. EVs were characterized by western blot and transmission electron microscopy (TEM), and uptake by PCa cells was verified by confocal microscopy. PPAT and PVAT explants were cultured overnight, EVs were isolated, and miRNA content expression profile was analysed. Pathway and functional enrichment analyses were performed seeking potential miRNA targets. In vitro functional studies were evaluated using PCa cells lines, miRNA inhibitors and target gene silencers. RESULTS: Western blot and TEM revealed the characteristics of EVs derived from PPAT (PPAT-EVs) samples. The EVs were up taken and found in the cytoplasm of PCa cells. Nine miRNAs were differentially expressed between PPAT and PVAT samples. The RORA gene (RAR Related Orphan Receptor A) was identified as a common target of 9 miRNA-regulated pathways. In vitro functional analysis revealed that the RORA gene was regulated by PPAT-EVs-derived miRNAs and was found to be implicated in cell proliferation and inflammation. CONCLUSION: Tumour periprostatic adipose tissue is linked to PCa tumour aggressiveness and could be envisaged for new therapeutic strategies.

ABSTRACT

Evans syndrome is a rare disease marked by a severe clinical course, high relapse rate, infectious and thrombotic complications, and sometimes fatal outcome. Management is highly heterogeneous. There are several case reports but few large retrospective studies and no prospective or randomised trials. Here, we report the results of the first consensus-based expert recommendations aimed at harmonising the diagnosis and management of Evans syndrome in adults. After reviewing the literature, we used a fuzzy Delphi consensus method, with two rounds of a 42-item questionnaire that were scored by a panel of 13 international experts from five countries using a 7-point Likert scale. Panellists were selected by the core panel on the basis of their personal experience and previous publications on Evans syndrome and immune cytopenias; they met virtually throughout 2023. The panellists recommended extensive clinical and laboratory diagnostic tests, including bone marrow evaluation and CT scan, and an aggressive front-line therapy with prednisone (with or without intravenous immunoglobulins), with different treatment durations and tapering for immune thrombocytopenia and autoimmune haemolytic anaemias (AIHAs). Rituximab was strongly recommended as first-line treatment in cold-type AIHA and as second-line treatment in warm-type AIHA and patients with immune thrombocytopenia and antiphospholipid antibodies, previous thrombotic events, or associated lymphoproliferative diseases. However, rituximab was discouraged for patients with immunodeficiency or severe infections, with the same applying to splenectomy. Thrombopoietin receptor agonists were recommended for chronic immune thrombocytopenia and in the case of previous grade 4 infection. Fostamatinib was recommended as third-line or further-line treatment and suggested as second-line therapy for patients with previous thrombotic events. Immunosuppressive agents have been moved to third-line or further-line treatment. The panellists recommended the use of recombinant erythropoietin in AIHA in the case of inadequate reticulocyte counts, use of the complement inhibitor sutimlimab for relapsed cold AIHA, and the combination of rituximab plus bendamustine in Evans syndrome secondary to lymphoproliferative disorders. Finally, recommendations were given for supportive therapy, platelet or red blood cell transfusions, and thrombotic and antibiotic prophylaxis. These consensus-based recommendations should facilitate best practice for diagnosis and management of Evans syndrome in clinical practice.

ABSTRACT

Acute laryngeal dyspnea is a life-threatening emergency often attributed to laryngeal tumors or inflammatory edema in adults. Primary laryngeal lymphomas are especially infrequent. As an aggressive subtype of B-cell non-Hodgkin lymphoma (NHL), mantle cell lymphoma (MCL) cases are particularly complex.  Herein, we present a case of laryngotracheal stenosis secondary to primary MCL. A comprehensive assessment, including in-office flexible laryngoscopy, revealed distinct findings within the supraglottis and subglottis. In the supraglottis, a submucosal lesion with well-defined, rounded edges was observed, while the subglottis exhibited a friable tumor occupying approximately 90% of the airway. This necessitated immediate intervention, leading to microlaryngoscopy, biopsy, and open tracheostomy. Due to the rarity of primary laryngeal lymphomas, they present a significant diagnostic challenge. Timely diagnosis is crucial to enable tailored therapeutic strategies and improved patient outcomes. This case highlights the importance of considering lymphomatous etiologies in the management of laryngotracheal stenosis and emphasizes the need for a multidisciplinary approach to optimize patient care.

ABSTRACT

Purpose: To assess the refractive and visual outcomes of hyperopic and astigmatic eyes implanted with a monofocal, aspheric, bitoric intraocular lens (IOL) with plate haptics following cataract surgery. Methods: The study evaluated 51 eyes implanted with the AT TORBI 709M IOL (Carl Zeiss Meditec AG, Jena, Germany) during a follow-up of 12-months. Refractive error, rotational stability, monocular uncorrected distance visual acuity (UDVA), monocular corrected distance visual acuity (CDVA), and contrast sensitivity were analyzed at 1-, 6-, and 12-months post-surgery. Results: At 12 months, the cumulative CDVA was 20/25 in 94.12% of eyes and 20/32 or better in 98.04%. The UDVA was the same as, or better than, the CDVA in 88.24% of eyes. The mean logMAR UDVA and CDVA values were 0.06 ± 0.11 and 0.00 ± 0.08, respectively. In addition, 92.16% of eyes were within ±0.50 D and 98.04% were within ±1.00 D of a spherical equivalent, and 86.27% of eyes had refractive astigmatism ≤0.50D and 100% were ≤1.00D. The mean spherical equivalent was 0.21 ± 0.31D and the mean refractive cylinder 0.34 ± 0.27D. The IOL rotation was 1.18 ± 1.35 degrees and all eyes had a rotation ≤5 degrees. The log contrast sensitivity functions were good and similar for all spatial frequencies during follow-up. Conclusion: Our results demonstrate that implantation of the AT TORBI 709M IOL in hyperopic and astigmatic eyes is effective and safe. The visual and refractive outcomes were good, showing excellent rotational stability.

ABSTRACT

BACKGROUND: The Childhood Trauma Questionnaire- Short Form (CTQ-SF) is among the most extensively studied and widely utilized instruments for evaluating childhood maltreatment. OBJECTIVE: The purpose of this study was to conduct a reliability generalization meta-analysis to estimate the average reliability of the CTQ-SF scores and its factors and search for study characteristics that can explain the variability in those coefficients. METHODS: A total of 39 independent samples provided 243 reliability estimates (Cronbach's alpha, McDonald's omega, and/or test-retest reliability coefficients) with the data at hand for the scores on the CTQ-SF and its five subscales for this meta-analysis. RESULTS: Random and mixed-effects models were employed for analyzing the data. The average Cronbach's alpha coefficient for the CTQ-SF total score was 0.891 (95 % CI: 0.868, 0.910). For the subscales, the average Cronbach's alpha coefficient ranged from 0.656 (Physical Neglect) to 0.916 (Sexual Abuse). The average McDonald's Omega coefficient for the CTQ-SF total score was 0.800 (95 % CI: 0.800 0.800). For the subscales, the average McDonald's Omega ranged from 0.740 (Physical Neglect) to 0.900 (Sexual Abuse). The average test-retest reliability for CTQ-SF total score was 0.788 (95 % CI: 0.635, 0.872), with the subscales ranging from 0.668 (Physical Neglect) to 0.709 (Physical Abuse). Moderator analyses revealed that some factors can affect reliability estimate. CONCLUSIONS: Although CTQ-SF and its five subscales have shown adequate reliability, it may vary as a function of the variability of scores, geographical location, financial source, and the affiliation of the main researcher.

ABSTRACT

BACKGROUND: Myocardial infarction (MI) is a serious condition affecting a considerable number of individuals, with important clinical consequences. Understanding the associated factors is crucial for effective management and prevention. This study aimed to (1) examine the association between MI and frailty in a sample of older European adults and (2) investigate the moderating effects of country and gender on this association. METHODS: A cross-sectional survey of 22,356 Europeans aged 60 years and older was conducted. The data come from the sixth wave of the Survey of Health, Ageing and Retirement in Europe. Frailty, MI, gender, and country were studied. RESULTS: Frailty is strongly associated with MI. Robust older adults are 13.31 times more likely not to have an MI. However, these odds drop to 5.09 if pre-frail and to 2.73 if frail. Gender, but not country, moderates this relationship. There is a strong association between MI and frailty in men, whereas for women, the association is not as strong. CONCLUSIONS: Frailty is highly associated with MI in European older adults. Country did not moderate the link between frailty and MI but gender does, with the relationship being notably stronger in men. The frailty-MI association remained significant even when controlling for a number of personal conditions and comorbidities.

ABSTRACT

Fostamatinib, a recently approved syk inhibitor used in adult primary immune thrombocytopenia (ITP), has been shown to be safe and effective in this disorder. However, clinical trial results may not be similarly reproduced in clinical practice. Here 138 ITP patients (both primary and secondary) from 42 Spanish centers who had been treated with fostamatinib were evaluated prospectively and retrospectively. The median age of our cohort (55.8% women) was 66 years (interquartile range, IQR, 56-80 years). The median time since ITP diagnosis at fostamatinib initiation was 51 months (IQR, 10-166 months). The median number of therapies prior to fostamatinib initiation was 4 (IQR, 2-5), including eltrombopag (76.1%), romiplostim (57.2%) and intravenous immunoglobulins (IVIG) (44.2%). Fifty-eight patients (42.0%) had signs/symptoms of bleeding in the month prior to treatment initiation. 79.0% of patients responded to fostamatinib with 53.6% complete responses (platelet count > 100 x 109 /L). Eighty-three patients (60.1%) received fostamatinib monotherapy achieving a high response rate (85.4%). The proportion of time in response during the 27-month period examined was 83.3%. The median time to platelet response was 11 days (IQR, 7-21 days). Sixty-seven patients (48.5%) experienced adverse events, mainly grade 1-2, the commonest of which were diarrhea (n = 28) and hypertension (n = 21). One patient had deep venous thrombosis and one patient developed acute myocardial infarction. Fostamatinib was shown to be effective with good safety profile in patients with primary and secondary ITP across a wide age spectrum in this real-world study.

ABSTRACT

Immune thrombocytopenia (ITP) is a common autoimmune hematological disorder. Despite this, diagnosis is still challenging due to clinical heterogeneity and the lack of a specific diagnostic test. New findings in the pathology and the availability of new drugs have led to the development of different guidelines worldwide. In the present study, the Delphi methodology has been used to get a consensus on the management of adult patients with ITP in Spain and to help in decision-making. The Delphi questionnaire has been designed by a scientific ad hoc committee and has been divided into 13 topics, with a total of 127 items, covering the maximum possible scenarios for the management of ITP. As a result of the study, a total consensus of 81% has been reached. It is concluded that this Delphi consensus provides practical recommendations on topics related to diagnosis and management of ITP patients to help doctors to improve outcomes. Some aspects remain unclear, without consensus among the experts. Thus, more advances are needed to optimize ITP management.


What is the context? Immune thrombocytopenia (ITP) is a hematologic autoimmune disease characterized by accelerated destruction and inadequate production of platelets mediated by autoantibodies (platelet count <100 × 109 /L).Despite being a common condition, its heterogeneous clinical course makes its diagnosis and management still a challenge.In recent years, new molecules with different mechanisms of action have emerged for the treatment of ITP.Due to the increasing information about the pathology and its therapies, several international guidelines have recently been established to provide recommendations for the management and treatment of ITP.There are still many patient scenarios and disease aspects which are not addressed in the guidelines.What is new? Our Spanish ITP Expert Group has developed a Delphi consensus study to provide recommendations and promote standardization of the management of adult patients with ITP in Spain.The scientific committee defined 127 statements for consensus, corresponding to 13 chapters: (i) Diagnosis of ITP, (ii) First-line treatment, (iii) Second-line treatment, (iv) Treatment of refractory patients, (v) Follow-up, (vi) Emergency and surgery, (vii) ITP in the elderly, (viii) ITP in pregnancy, (ix) Anticoagulation and antiplatelet, (x) Secondary ITP, (xi) Quality of life, (xii) Discontinuation of TPO-RA, and (xiii) ITP and Covid.The total number of agreed statements achieved was 103, giving a final percentage of consensus in the Delphi questionnaire of 81%.What is the impact? This Delphi consensus provides recommendations based on real clinical practice data, regarding the diagnosis, treatment, and management of patients and scenarios in ITP to assist clinicians in addressing this disease and achieving optimal outcomes for the patient.

ABSTRACT

Introduction: Immune thrombocytopenia (ITP) management with co-existing acute coronary syndrome (ACS) remains challenging as it requires a clinically relevant balance between the risk and outcomes of thrombosis and the risk of bleeding. However, the literature evaluating the treatment approaches in this high-risk population is scarce. Methods and Results: In this review, we aimed to summarize the available literature on the safety of ITP first- and second-line therapies to provide a practical guide on the management of ITP co-existing with ACS. We recommend holding antithrombotic therapy, including antiplatelet agents and anticoagulation, in severe thrombocytopenia with a platelet count < 30 × 109/L and using a single antiplatelet agent when the platelet count falls between 30 and 50 × 109/L. We provide a stepwise approach according to platelet count and response to initial therapy, starting with corticosteroids, with or without intravenous immunoglobulin (IVIG) with a dose limit of 35 g, followed by thrombopoietin receptor agonists (TPO-RAs) to a target platelet count of 200 × 109/L and then rituximab. Conclusion: Our review may serve as a practical guide for clinicians in the management of ITP co-existing with ACS.

ABSTRACT

OBJECTIVES: We aimed to explore the reciprocal effects of social participation, loneliness, and physical inactivity over a period of 6 years in a representative sample of European adults over 50 years old. DESIGN: A longitudinal study with a six-year follow-up period was conducted. SETTING: Four waves of the Survey of Health, Ageing and Retirement in Europe project were used. PARTICIPANTS: This study includes 64,887 participants from Europe and Israel, who were aged 50 or older at the first time. MEASUREMENTS: The relationship between participation in social activities, loneliness and physical inactivity was analyzed, controlling for age, gender, and disability. A series of cross-lagged panel models (CLPMs) were applied to analyze the relationships among these variables. RESULTS: A CLPM with equal autoregressive cross-lagged effects across waves was the best fit to the data (χ2 = 7137.8, CFI = .972, RMSEA = .049, SRMR = .036). The autoregressive effects for the three variables showed high stability across waves, and all the cross-lagged effects in the model were statistically significant. Social activity and physical inactivity maintained a strong negative cross-lagged effect, while their cross-lagged effects on loneliness were comparatively smaller. Social activity had a positive cross-lagged effect on loneliness, while physical inactivity had a negative cross-lagged effect on loneliness. CONCLUSIONS: These findings highlight the importance of promoting physical activity and social participation and addressing loneliness through targeted interventions in older adults.

ABSTRACT

BACKGROUND: The types of social networks, their prevalence, and their relationship to health outcomes in older age have been different across countries and cultures. Most of the literature has focused on USA or in European countries and little is known about the social network typologies among older adults from Japan. This study aimed to identify these patterns of social network typologies and examine the differences in sociodemographic and related to health variables. METHODS: 23894 participants from the JAGES project (2019), aged 65 or older (M = 74.74, DT = 6.39) from Japan. Statistical analyses included Latent Profile Analysis (LPA) followed by ANOVAs, Chi square and multinomial logistic regressions tests to compare the profiles. RESULTS: Four profiles were identified: family (66.9%), spouse (16.6%), diverse (14.5%), and neighbor/others (1.9%). The profiles differ statistically (p < 0.001) in all sociodemographic characteristics and in the means of depression, loneliness, self-perceived health, and happiness. Compared with the "family" network, younger men, with fewer chronic illnesses but higher levels of depression and loneliness were more likely to be in the "spouse" profile, older women with lower socioeconomic status, but less lonely and happier in the "diverse" profile and adults who still working, have lower socioeconomic status and are less happy into the "neighbors/others" group. DISCUSSION: We discuss the differences between the profiles found, the potential differences with previous studies and the specific cultural Japanese nuances that may explain the characteristics of the network types founded.

ABSTRACT

BACKGROUND: Clarkson's disease is a very rare entity characterised by acute episodes of systemic oedema and severe hypotension associated with paraproteinaemia. Its classical treatment relies on methylxanthine combined with terbutaline. Although this prophylactic therapy reduces the mortality rate, relapses are frequent. Eighty percent of patients with Clarkson's disease present with monoclonal gammopathy of unknown significance (MGUS). The risk of progression to multiple myeloma is 1% per year. CASE DESCRIPTION: Here, we present a 49-year-old woman who suffered multiple such episodes requiring treatment in the intensive care unit. Treatment with terbutaline and theophylline was ineffective. She was diagnosed with multiple myeloma (MM) 8 years after the first of these acute episodes. Antimyeloma treatment with bortezomib and dexamethasone was started, followed by autologous haemopoietic transplantation, with no further acute episodes since then. CONCLUSION: Our case is, to our knowledge, unique because eradication of MM was followed by complete disappearance of acute episodes of capillary leakage. Our case report is also the first to support the use of bortezomib and dexamethasone in this setting. Furthermore, autologous peripheral blood progenitor cell transplantation consolidated the MM stringent complete remission achieving a very long progression-free survival (> 11 years) of both MM and Clarkson's disease.

ABSTRACT

Primary care antimicrobial stewardship program (ASP) interventions can reduce the over-prescription of unnecessary antibiotics, but the impact on the reduction in bacterial resistance is less known, and there is a lack of available data. We implemented a prolonged educational counseling ASP in a large regional outpatient setting to assess its feasibility and effectiveness. Over a 5-year post-implementation period, which was compared to a pre-intervention period, a significant reduction in antibiotic prescriptions occurred, particularly those associated with greater harmful effects and resistance selection. There was also a decrease in methicillin-resistant Staphylococcus aureus (MRSA) strains and in their co-resistance to other antibiotics, particularly those with an ecological impact.

ABSTRACT

OBJECTIVES: Cognitive decline is common in the old age, but some evidence suggests it may already occur during adulthood. Previous studies have linked age, gender, educational attainment, depression, physical activity, and social engagement to better cognitive performance over time. However, most studies have used global measures of cognition, which could mask subtle changes in specific cognitive domains. The aim of this study is to examine trajectories of recent and delayed memory recall from a variable-centered perspective, in order to elucidate the impact of age, gender, educational attainment, depression, physical activity, and social engagement on recent and delayed memory both at initial time and across a 10-year period. DESIGN AND PARTICIPANTS: The sample was formed by 56,616 adults and older adults that participated in waves 4 to 8 of the Survey of Health, Aging and Retirement in Europe (SHARE). ANALYSES: We used latent growth modeling to establish latent recent and delayed memory trajectories, and then tested the effects of the aforementioned covariates on the latent intercept and slopes. RESULTS: Results showed that both recent and delayed recall display a quadratic trajectory of decline. All covariates significantly explained initial levels of immediate and delayed recall, but only a few had statistically significant effects on the slope terms. CONCLUSIONS: We discuss differences between present results and those previously reported in studies using a person-centered approach. This study provides evidence of memory decline during adulthood and old adulthood. Further, results provide support for the neural compensation reserve theory.

ABSTRACT

AIMS: Patients with heart failure (HF) can exhibit kinesiophobia, an excessive, debilitating, and irrational fear of movement. This study aimed to enhance the understanding of kinesiophobia in patients with HF by analysing associations with the following variables: musculoskeletal pain, quality of life, quality of sleep, functional capacity, disability, frailty, sex, and age. METHODS AND RESULTS: In this cross-sectional study, 107 participants were included, with ages ranging from 28 to 97 years (57% men, mean age 73.18 ± 12.68 years). Multiple regression analyses were performed with all variables, including polynomial regressions for variables with a non-linear relationship. Kinesiophobia was significantly correlated (P < 0.01) with musculoskeletal pain, quality of life, quality of sleep, functional capacity, disability, and being at risk of frailty, while age and sex were not statistically significant. Frailty disability and musculoskeletal pain intensity were variables linearly associated with kinesiophobia, while quality of sleep and disability had a non-linear relationship with kinesiophobia. CONCLUSION: Kinesiophobia needs to be evaluated and better understood in patients with HF to improve physical activity and exercise adherence. This study found that musculoskeletal pain intensity, quality of sleep, disability, and frailty risk have a significant association with kinesiophobia in patients with HF. Our results suggest multi-dimensional associations of kinesiophobia in patients with HF, which require further examination and understanding.

ABSTRACT

Introduction: This work represents the first attempt to obtain evidence of the validity of an entrepreneurial intention questionnaire in the adolescent population of a Latin American or Caribbean country. The objectives are to study the factor structure, the reliability, the external validity and to test the gender invariance of the Entrepreneurial Intention Questionnaire, in its adaptation for adolescents. Method: The sample consisted of 708 adolescents from the Dominican Republic with a mean age of 15.49, 65.2% of whom were women and 35.8% were men. Analyses included confirmatory factor analysis, Cronbach's Alpha and Omega scores for reliability, correlations, and a gender invariance routine. Finally, latent means of females and males are compared. Results: The confirmatory factor analysis showed a good fit to the data and the reliability results were adequate. In addition, the correlations with the Entrepreneurial Attitudes Scale for Students were positive and statistically significant. Also, strict gender invariance was successfully verified. Although males presented a higher subjective norm, females showed higher entrepreneurial intentions. Conclusions: The Entrepreneurial Intention Questionnaire shows adequate psychometric properties and proves useful in conducting research on the promotion of entrepreneurship in early stages.

ABSTRACT

(analítico) Los factores de riesgo y protección pueden ser utilizados para evaluar, prevenir e intervenir en el maltrato infantil. El objetivo de este estudio es analizar longitudinalmente el riesgo en la infancia y la adolescencia, para determinar qué factores pueden ser empleados como indicadores de evolución. Se empleó una muestra de 102 niños, niñas y adolescentes que participaban en el sistema de bienestar infantil español, en tres momentos temporales. Los resultados indicaron que existe una evolución del riesgo, con una tendencia general de disminución de riesgos e incremento de elementos protectores. Nuestros hallazgos identificaron la existencia de factores dinámicos y estáticos. Este estudio pone de manifiesto la relevancia de la atención e intervención continuada y a largo plazo para fortalecer los factores de protección y disminuir los de riesgo en niños, niñas y adolescentes.


(analytical) Risk and protective factors can be used for risk and needs assessments, prevention, and intervention in cases involving mistreatment of children. The aim of this study is to provide a longitudinal analysis of risks and vulnerabilities in childhood and adolescence, with the goal of determining which factors can be used as indicators for progress with cases. A sample of 102 children and adolescents supported by the child welfare system in Spain was used along with measurements based on three different points in time. The study's results indicated that there is a change in risk levels, with a general trend of decreasing risk and increasing protective elements. The study's findings identified the existence of a group of dynamic factors and another group of static factors. This study highlighted the relevance of continuous and long-term care and intervention in order to strengthen protection and decrease risks for children.
