RESUMO

To characterize nirsevimab in the prevention of RSV, children from the Phase 3 MELODY trial were followed through their second RSV season. No increase in medically attended RSV lower respiratory tract infections or evidence of antibody-dependent enhancement of infection or disease severity was found for nirsevimab vs placebo recipients. Clinical Trial Registration: Clinicaltrials.gov, NCT03979313, https://clinicaltrials.gov/ct2/show/NCT03979313.

RESUMO

BACKGROUND: Sexual dysfunction (SD) associated with oncological treatment is a common and understudied disorder. Our aim was to characterize SD in a cohort of Spanish patients. METHODS: Analytic observational study in patients included in the CLARIFY H2020 project at the Hospital Universitario Puerta de Hierro. Clinical variables and validated measures of sexual function were collected from October 2020 to May 2022. Frequency and quality of sexual activity were assessed. Descriptive, trend associations, and logistic regression analyses were performed. RESULTS: A total of 383 patients were included: breast cancer 68.14% (261), lung cancer 26.37% (101), and lymphoma 5.50% (21). Mean age was 56.5 years (range 33-88). 19.58% (75) were men and 80.42% (308) were women. 69% and 31% of men and women, respectively, reported being sexually active. The absolute frequency of overall sexual dissatisfaction was 76% in women and 24% in men. Women with breast cancer were most likely to have severe sexual dysfunction. Those with early disease had resolved complaints after 5 years. In multinomial logistic regression, significant associations were found in women with metastatic breast cancer and severe disorders of arousal (p 0.000), lubrication (p 0.002), orgasm (p 0.000), as well as dissatisfaction with sexual performance (p 0.000) and global sexual dissatisfaction (p 0.000). Women with lung cancer have severe arousal dysfunction (p 0.016) and global sexual dissatisfaction (p 0.044). CONCLUSIONS: Our population has a high prevalence of SD, which supports the need to increase awareness of this disorder among the medical oncology team and the importance of including sexual health assessment in oncological patient follow-up.

RESUMO

Nirsevimab is an extended half-life monoclonal antibody specific for the prefusion conformation of the respiratory syncytial virus (RSV) F protein, which has been studied in preterm and full-term infants in the phase 2b and phase 3 MELODY trials. We analyzed serum samples collected from 2,143 infants during these studies to characterize baseline levels of RSV-specific immunoglobulin G antibodies and neutralizing antibodies (NAbs), duration of RSV NAb levels following nirsevimab administration, the risk of RSV exposure during the first year of life and the infant's adaptive immune response to RSV following nirsevimab administration. Baseline RSV antibody levels varied widely; consistent with reports that maternal antibodies are transferred late in the third trimester, preterm infants had lower baseline RSV antibody levels than full-term infants. Nirsevimab recipients had RSV NAb levels >140-fold higher than baseline at day 31 and remained >50-fold higher at day 151 and >7-fold higher at day 361. Similar seroresponse rates to the postfusion form of RSV F protein in nirsevimab recipients (68-69%) compared with placebo recipients (63-70%; not statistically significant) suggest that while nirsevimab protects from RSV disease, it still allows an active immune response. In summary, nirsevimab provided sustained, high levels of NAb throughout an infant's first RSV season and prevented RSV disease while allowing the development of an immune response to RSV.

RESUMO

Background: Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment. However, despite their excellent therapeutic effect, these medications typically result in a broad spectrum of toxicity reactions. Immune-related cardiotoxicity is uncommon but can be potentially fatal, and its true incidence is underestimated in clinical trials. The aim of this study is to assess the incidence and identify risk factors for developing a cardiac event in patients treated with ICIs. Methods: We conducted a single-institution retrospective study, including patients treated with ICIs in our center. The main outcomes were cardiac events (CE) and cardiovascular death. Results: A total of 378 patients were analyzed. The incidence of CE was 16.7%, during a median follow-up of 50.5 months. The multivariable analysis showed that age, a history of arrhythmia or ischemic heart disease, and prior immune-related adverse events were significantly associated with CE. Conclusion: CE during ICI treatment are more common than currently appreciated. A complete initial cardiovascular evaluation is recommended, especially in high-risk patients, being necessary a multidisciplinary approach of a specialized cardio-oncology team.

RESUMO

Honeys produced by species other than Apis mellifera are little known. The objective of this study was to carry out sensory and physicochemical analyses of 62 samples to characterize honeys from nine species of stingless bees from Mexico and Guatemala. Analyses were performed at the sensory level and at the physicochemical level. Qualitative and quantitative data were studied using the multivariate non-metric multidimensional scaling (NMDS) statistical technique, with the Gower metric. According to the stress value (p > 0.2), the most significant parameters were at the sensory level, for visual evaluation, physical state, color, and appearance; for olfactory-taste evaluation, elemental sweet and acid tastes; for tactile evaluation, consistency, and crystallization, and for physicochemical evaluation, pH, electrical conductivity and reducing sugars. Data analysis showed that Melipona beecheii honeys formed a defined group, with similar sensory characteristics and physicochemical values, even taking into account their place of origin. Frieseomelitta nigra honeys also showed significant differences with the other honeys analyzed. Our work suggests that the entomological origin is the main factor that determines the characteristics of honey, and that the floral origin is the secondary factor, a hypothesis that should be verified in future works.

RESUMO

BACKGROUND: Artificial intelligence (AI) has contributed substantially in recent years to the resolution of different biomedical problems, including cancer. However, AI tools with significant and widespread impact in oncology remain scarce. The goal of this study is to present an AI-based solution tool for cancer patients data analysis that assists clinicians in identifying the clinical factors associated with poor prognosis, relapse and survival, and to develop a prognostic model that stratifies patients by risk. MATERIALS AND METHODS: We used clinical data from 5275 patients diagnosed with non-small cell lung cancer, breast cancer, and non-Hodgkin lymphoma at Hospital Universitario Puerta de Hierro-Majadahonda. Accessible clinical parameters measured with a wearable device and quality of life questionnaires data were also collected. RESULTS: Using an AI-tool, data from 5275 cancer patients were analyzed, integrating clinical data, questionnaires data, and data collected from wearable devices. Descriptive analyses were performed in order to explore the patients' characteristics, survival probabilities were calculated, and a prognostic model identified low and high-risk profile patients. CONCLUSION: Overall, the reconstruction of the population's risk profile for the cancer-specific predictive model was achieved and proved useful in clinical practice using artificial intelligence. It has potential application in clinical settings to improve risk stratification, early detection, and surveillance management of cancer patients.

RESUMO

Introduction: Short sleep, physical inactivity, and being locked up are risk factors for weight gain. Objective: We evaluated weight gain according to sex, age, hours of sleep and physical activity in university students from 10 Latin American countries during the COVID-19 pandemic. Methods: Cross-sectional and multicenter study (n = 4880). Results: The average age was 22.5 ± 4.4 years. 60.2% were currently locked up. 73.6% were women, 48.2% increased their body weight, 66% reported insufficient sleep hours, and 65.9% were inactive. Women gained more weight than men (73.2%) and younger students gained more weight (85.1%). Those who had insufficient sleep hours gained most weight (67.6%). Inactive participants gained most weight (74.7%). Students who have insufficient sleep are 21% more likely to have changes in body weight compared to students who have optimal sleep. Conclusion: The increase in body weight and its risk factors during confinement should be considered as emerging from public health.

RESUMO

AIM: Immune checkpoint inhibitors (ICIs) are a cornerstone in cancer treatment but they can induce immune-related adverse events (irAEs). Furthermore, patients with pre-existing autoimmune and/or inflammatory disease (AID) have been excluded from clinical trials. The objective of this study is to evaluate the efficacy and safety of ICIs in patients with cancer and AID. MATERIALS & METHODS: This is an observational, retrospective study carried out at the Medical Oncology Department of Hospital Universitario Puerta de Hierro, Majadahonda, Madrid between January 2016 and December 2018. RESULTS: A total of 202 cancer patients treated with ICIs were included, 15 (7, 4%) of them had pre-existing autoimmune diseases. The most frequent pre-existing AID were thyroid diseases (33.3%): autoimmune hypothyroidism, Graves-Basedow disease and Hashimoto's thyroiditis. Three patients had psoriasis, two antinuclear antiboides + polyarthritis, one rheumatoid arthritis, another latent autoimmune diabetes in adults, another systemic lupus erythematosus and the last one, a polymyalgia rheumatica. In this series, the majority of patients (73.33%) did not experience any flare up of their autoimmune disease. In patients who had AID flare up, this was treated with corticosteroids. The most frequent cause of immunotherapy discontinuation was tumor progression (40%). A total of 20% of patients had to discontinue immunotherapy due to toxicity. CONCLUSION: In our series, AID flare ups or irAEs in patients with pre-existing AID who receive immunotherapy are not very common and can often be controlled without interrupting treatment. Prospective studies are needed to establish the incidence of irAEs in patients with pre-existing autoimmune conditions, evaluate risk-benefit and elaborate management clinical guidelines in this population.

RESUMO

BACKGROUND: Eating disorders are characterized by a persistent disturbance that alters food intake and it is often accompanied by anxiety, depression, low self-esteem, or reduced functional capacity and quality of life. Animal-assisted therapies (AAT) have shown benefits in these variables in children and adult populations. Thus, the present pilot study will aim to evaluate the effects of a dog-assisted therapy on the eating disorders symptoms, mental, psychosocial, and physical health, quality of life, and handgrip strength of adolescents suffering from eating disorders. METHODS: The current pilot study will involve 32 patients, who will be assigned to a control or an experimental group. Intervention will be conducted once a week for seven weeks. Neither the experimental nor the control group will discontinue their usual care. The main outcome measures will be the eating disorder symptoms and the health-related quality of life measured with standardized questionnaires, while the secondary variables will be anxiety, depression, character, behavior, strength, and body mass. CONCLUSIONS: This pilot-controlled trial will be the first to evaluate the effects of dog-assisted therapy on the physical and mental health of adolescents with eating disorders. Significant improvements, in the primary and secondary outcomes, may be expected based on the known benefits of AAT on self-esteem, stress, and self-control in different populations. Finally, although the program is focused on the improvement of adolescents' health, animal welfare will be a priority in this study.

RESUMO

INTRODUCTION: Madrid has been the epicenter of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in Spain. We analyzed our experience with SARS-CoV-2 infected and cancer patients. PATIENTS AND METHODS: We included patients from March 1 to April 30 2020 at Hospital Universitario Puerta de Hierro, Majadahonda, Madrid (Spain). The inclusion criteria were diagnosis of SARS-CoV-2 infection made by reverse transcription polymerase chain reaction (RT-PCR) of nasopharyngeal specimens in cancer patients who were admitted to the hospital due to the need for respiratory support. The exclusion criteria were suspected cases not confirmed. The primary objective was to analyze the mortality rates of patients with cancer, especially those with lung cancer and COVID-19. RESULTS: Overall in-hospital mortality of cancer patients with coronavirus disease 2019 (COVID-19) was 15.2% similar to 12.7% of the global COVID-19 hospitalized population (p=0.615) and greater than that of patients admitted without SARS-CoV-2 infection during the same period 4.3% (p<0.001). Among 653 patients receiving active cancer therapy during the study period, 24 (3.7%) developed COVID-19 and required admission, 4.2% of those receiving chemotherapy, 9.5% immunotherapy and 2.1% targeted therapies. Lung and breast cancer were the most frequent cancer types (26.1%), followed by colorectal cancer (19.6%). Mortality in patients with lung cancer was 25%. The univariate analysis comparing patients who developed a serious event to those who did not showed that the higher Brescia index, CURB-65 scale, lactate dehydrogenase (LDH) or C-reactive protein (CRP) were the risk factors of developing severe complications. CONCLUSION: Patients with cancer, especially lung cancer, and SARS-CoV-2 infection have a worse overall prognosis than the general population.

RESUMO

PREMISE: Abiotic factors and plant species traits have been shown to drive latitudinal gradients in herbivory, and yet, population-level factors have been largely overlooked within this context. One such factor is plant density, which may influence the strength of herbivory and may vary with latitude. METHODS: We measured insect herbivory and conspecific plant density (CPD) of oak (Quercus robur) seedlings and saplings along a 17° latitudinal gradient (2700 km) to test whether herbivory exhibited a latitudinal gradient, whether herbivory was associated with CPD, and whether such an association changed with latitude. RESULTS: We found a positive but saturating association between latitude and leaf herbivory. Furthermore, we found no significant relationship between CPD and herbivory, and such lack of density effects remained consistent throughout the sampled latitudinal gradient. CONCLUSIONS: Despite the apparently negligible influence of plant density on herbivory for Q. robur, further research with other plant taxa and in different types of plant communities are needed to investigate density-dependent processes shaping geographical variation in plant-herbivore interactions.

RESUMO

OBJECTIVE: To present the adaptations to treatment protocols made in a child and adolescent eating disorders (ED) unit during the eight-week confinement period mandated in response to the COVID-19 pandemic and examine clinical and treatment variables in the outpatient, day hospital, and inpatient care programs. METHOD: Description of the implementation of a combined teletherapy program for outpatient and day-hospital patients and the adaptations made to the inpatient protocol. Retrospective review of medical records and analysis of general and specific variables related to the pandemic and confinement. RESULTS: We held 1,329 (73.10%) telehealth consultations and 489 (26.9%) face-to-face outpatient visits with 365 patients undergoing treatment in the outpatient clinic or day hospital. Twenty-eight (7.67%) were initial evaluations. Twenty-two patients were newly admitted and 68 ED-related emergencies were attended. Almost half of the children and adolescents studied experienced reactivation of ED symptoms despite treatment, and severe patients (25%) presented self-harm and suicide risk. CONCLUSIONS: The implementation of a combined teletherapy program has enabled continuity of care during confinement for children and adolescents with ED. Delivery of treatment to adolescents in the day hospital program posed the biggest challenge due to their greater degrees of severity and higher hospitalization rates. An adapted inpatient program should be maintained throughout confinement, as the need for hospitalization of children and adolescents with ED does not decrease with lockdown.

RESUMO

OBJECTIVE: The current multicentre randomized controlled trial assessed the clinical efficacy of a combined mHealth intervention for eating disorders (EDs) based on cognitive behavioral therapy (CBT). METHOD: A total of 106 ED patients from eight different public and private mental health services in Spain were randomly assigned to two parallel groups. Patients of the experimental group (N = 53) received standard face-to-face CBT plus a mobile intervention through an application called "TCApp," which provides self-monitoring and an online chat with the therapist. The control group (N = 53) received standard face-to-face CBT only. Patients completed self-report questionnaires on ED symptomatology, anxiety, depression, and quality of life, before and after treatment. RESULTS: Significant reductions in primary and secondary outcomes were observed for participants of both groups, with no differences between groups. Results also suggested that the frequency with which patients attended their referral mental health institution after the intervention was lower for patients in the experimental group than for those in the control group. DISCUSSION: The current study showed that CBT can help to reduce symptoms relating to ED, regardless of whether its delivery includes online components in addition to traditional face-to-face treatment. Besides, the additional component offered by the TCApp does not appear to be promising from a purely therapeutic perspective but perhaps as a cost-effective tool, reducing thus the costs and time burden associated with weekly visits to health professionals.

RESUMO

BACKGROUND: Biological differences between the sexes have a major impact on disease and treatment outcome. In this paper, we evaluate the prognostic value of sex in stage IV non-small-cell lung cancer (NSCLC) in the context of routine clinical data, and compare this information with other external datasets. METHODS: Clinical data from stage IV NSCLC patients from Hospital Puerta de Hierro (HPH) were retrieved from electronic health records using big data analytics (N = 397). In addition, data from the Spanish Lung Cancer Group (GECP) Tumor Registry (N = 1382) and from a published study available from the cBioPortal (MSK) (N = 601) were analyzed. Survival curves were estimated using the Kaplan-Meier method. A Cox proportional hazards regression model was used to assess the prognostic value of sex. A meta-analysis to compare the outcome for males and females in terms of overall survival (OS) and progression free survival (PFS) was performed. RESULTS: The median OS time was 12 months for males and 19 months for females (overall HR = 0.77; 95% CI: 0.68-0.87; P < 0.001). Similarly, females with stage IV NSCLC harboring an EGFR-sensitizing mutation lived significantly longer than males (median OS: males, 19 months; females, 32 months) with a lower risk of death compared with males (overall HR = 0.75; 95% CI: 0.67-0.84). In addition, female patients benefited more from EGFR inhibitors in terms of PFS and OS (overall HR = 0.45; 95% CI: 0.32-0.64, and HR = 0.62; 95% CI: 0.48-0.80, respectively). Median PFS was 21 months in females and 12 months in males (P < 0.001). CONCLUSIONS: Using routine clinical data we confirmed the previous finding that among stage IV NSCLC patients, females had a significantly better prognosis than males. The effect size of the sex was notable, highlighting the fact that survival rates are usually estimated and patients are generally managed without considering the sexes separately, which may lead to suboptimal results.

Es una causa importante de pérdida visual en adultos, con consecuencias médicas, sociales y financieras significativas. El objetivo fue evaluar los hábitos alimentarios y estado nutricional en diabéticos con retinopatía que acuden a la Clínica Vista 10 de la ciudad de Asunción entre setiembre y noviembre del año 2018. Estudio descriptivo, observacional de corte transverso que incluyó 50 pacientes, Siendo la mayor parte de ellos del sexo femenino (65%), la edad media fue de 62,8±11,3 años, el 66% (n=33) estaba casado con nivel educativo primario (n=20;40%) y vivía en Gran Asunción (n= 46; 92%). Respecto a la frecuencia de consumo de alimentos, se encontró que casi la totalidad de la población realizaba el desayuno (96%). El 70% consumía lácteos descremados menos de la cantidad recomendada. Solo un 20% consumía frutas todos los días. Un poco más de la mitad (52%) consumía verduras todos los días. El 70% consumía pescado por debajo de las recomendaciones establecidas, y el 78% consumía legumbres menos de la cantidad recomendada. Más de la mitad (58%) consumía alimentos integrales por debajo de las recomendaciones. El 54% consumía comida casera todos los días y el 56% realizaba la cena todos los días. Más de la mitad de los participantes presentó sobrepeso u obesidad. Los hábitos de la población son deficientes, en relación al consumo de frutas, lácteos según las recomendaciones de las Guías Alimentarias del Paraguay

RESUMO

BACKGROUND: Cancer therapy-induced cardiomyopathy (CCM) is associated with cumulative drug exposures and preexisting cardiovascular disorders. These parameters incompletely account for substantial interindividual susceptibility to CCM. We hypothesized that rare variants in cardiomyopathy genes contribute to CCM. METHODS: We studied 213 patients with CCM from 3 cohorts: retrospectively recruited adults with diverse cancers (n=99), prospectively phenotyped adults with breast cancer (n=73), and prospectively phenotyped children with acute myeloid leukemia (n=41). Cardiomyopathy genes, including 9 prespecified genes, were sequenced. The prevalence of rare variants was compared between CCM cohorts and The Cancer Genome Atlas participants (n=2053), healthy volunteers (n=445), and an ancestry-matched reference population. Clinical characteristics and outcomes were assessed and stratified by genotypes. A prevalent CCM genotype was modeled in anthracycline-treated mice. RESULTS: CCM was diagnosed 0.4 to 9 years after chemotherapy; 90% of these patients received anthracyclines. Adult patients with CCM had cardiovascular risk factors similar to the US population. Among 9 prioritized genes, patients with CCM had more rare protein-altering variants than comparative cohorts ( P≤1.98e-04). Titin-truncating variants (TTNtvs) predominated, occurring in 7.5% of patients with CCM versus 1.1% of The Cancer Genome Atlas participants ( P=7.36e-08), 0.7% of healthy volunteers ( P=3.42e-06), and 0.6% of the reference population ( P=5.87e-14). Adult patients who had CCM with TTNtvs experienced more heart failure and atrial fibrillation ( P=0.003) and impaired myocardial recovery ( P=0.03) than those without. Consistent with human data, anthracycline-treated TTNtv mice and isolated TTNtv cardiomyocytes showed sustained contractile dysfunction unlike wild-type ( P=0.0004 and P<0.002, respectively). CONCLUSIONS: Unrecognized rare variants in cardiomyopathy-associated genes, particularly TTNtvs, increased the risk for CCM in children and adults, and adverse cardiac events in adults. Genotype, along with cumulative chemotherapy dosage and traditional cardiovascular risk factors, improves the identification of patients who have cancer at highest risk for CCM.

RESUMO

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder1 and consists in a persistent pattern of inattention and / or hyperactivity - impulsivity that interferes with the functioning or development of the person who suffers from it. Because it is a disorder that is present since childhood, the treatment of these patients should be multimodal, and it should include doctors, therapists, teachers and parents2. The choice of a pharmacological treatment adjusted to the specific needs of the patient optimizes the results of the intervention programs. In 1997, the National Institute of Mental Health (NIMH) started the study of multimodal treatment of attention deficit hyperactivity disorder (MTA), and this constitutes a landmark in the history of treatment research in child psychopathology. MTA is the largest study of its kind ever undertaken. In the present article we intend to review the existing clinical evidence about the results of the MTA from the nineties to the current date.

RESUMO

La modernización alimentaria ha llevado a una mayor disponibilidad de alimentos industrializados, ricos en azúcares simples, grasas saturadas y altos en sodio; a ese patrón se le ha considerado la "dieta occidental", concomitante al incremento del sobrepeso y obesidad, y al aumento de la morbilidad y mortalidad por enfermedades crónico-degenerativas. El objetivo de este estudio fue determinar la adecuación de la composición nutricional de alimentos procesados y ultraprocesados de acuerdo al Perfil de Alimentos de la Organización Panamericana de la Salud respecto a los nutrientes críticos según lo declarado en el etiquetado nutricional. Estudio transversal, observacional y descriptivo en el que se analizaron 80 productos: 38 procesados y 42 ultraprocesados. Dentro de la categoría de ¨Cereales¨, en comparación con los criterios del Perfil de Nutrientes de la OPS, se ha encontrado que la razón sodio/Kcal supera la proporción 1:1. Además, los azúcares agregados superan el 10% del total de Kcal de los productos en un 24%. En la categoría de ¨Bebidas¨, los azúcares agregados sobrepasan las cantidades sugeridas por la OPS en un 15% del 10% permitido. En conclusión se encontraron que en los alimentos procesados muchos ingredientes sobrepasan lo permitido o recomendado por la OPS, por lo que el mejor consejo dietético es basar las dietas en alimentos frescos y mínimamente procesados, y la preparación de platos y comidas frescos(AU)
