ABSTRACT
Introducción: El metilfenidato (MTF) es un psicoestimulante que aumenta frecuencia cardiaca (FC) y presión arterial (PA), lo cual a largo plazo podría modificar la geometría del ventrículo izquierdo (VI) y alterar sus propiedades funcionales, principalmente la diastólica. Material y métodos: Estudio prospectivo, longitudinal y comparativo tipo caso-caso en niños y adolescentes sanos diagnosticados de trastorno por déficit de atención e hiperactividad (TDAH) tratados con MTF durante 3 años. Se valoró pre y postratamiento PAS/PAD, geometría ventricular, función sistólica y diastólica. Resultados: Incluimos a 112 pacientes, completando 73. El 75,3% varones, entre 4-15 años (9±2,6), con índice de masa corporal de 18,27±3,75 y una dosis media de MTF de 0,9±0,17mg/kg/día. Objetivamos aumento de PAS/PAD de 3,7±9mmHg (p = 0,004) y 2±11,5mmHg, respectivamente. No tuvimos ningún evento cardiovascular grave, cambios estructurales ni variación en los parámetros de función sistólica estudiados. Sin embargo, encontramos un aumento discreto, pero progresivo y significativo del tiempo de relajación isovolumétrica del VI (p = 0,046) y del tiempo de desaceleración (p = 0,016) indicativos de alteración en la relajación. No observamos variación en los parámetros relacionados con la distensibilidad ni con las presiones diastólicas tempranas y ningún paciente cumplió criterios de disfunción diastólica. Conclusiones: El incremento de PAS/PAD y las alteraciones de la relajación del VI objetivadas podrían ser un indicador precoz de una posible disfunción diastólica y riesgo cardiovascular a largo plazo.(AU)
Introduction: Although methylphenidate (MPH) used for treatment of Attention deficit hyperactivity disorder (ADHD) are considered safe in healthy children and adolescents in the short and medium term, there is a widespread concern about long-term cardiovascular safety. Material and methods: Interventional, prospective, longitudinal and comparative study with a crossover design to evaluate the cardiovascular impact of the treatment with MPH in healthy children and adolescents diagnosed with ADHD. A protocol for the cardiovascular evaluation was established at a basal point, after the first and the second year of the beginning with treatment based on the monitoring of Blood pressure (BP) and echocardiographic follow-up of the systolic and diastolic functions, and structural cardiac properties. Results: 73 patients completed the study, with an average age of 9+/- 2.6 years, 75.3% were male and the majority were thin (64.4%). We found an increase in Systolic and Diastolic BP of 3.7±9mmHg (P).004) and 2±11,5mmHg respectively. There were no severe cardiovascular events. We didnt find any echocardiographic alterations namely on the structural properties or parameters of systolic function. Regarding diastolic function, a significant increase in the isovolumic relaxation time (IVRT) (P=.046) and deceleration time (P=.016) was observed. However, no significant alterations in the parameters related to distensibility of the LV neither in the early diastolic pressure were found. Conclusion: Further studies are needed to evaluate the impact of psychostimulants as a modifiable long-term Cardiovascular Risk Factor.(AU)

ABSTRACT
Immunotherapy has become a new paradigm in oncology, improving outcomes for several types of cancer. However, there are some aspects about its management that remain uncertain. One of the key points that needs better understanding is the interaction between immunotherapy and gut microbiome and how modulation of the microbiome might modify the efficacy of immunotherapy. Consequently, the negative impact of systemic antibiotics and corticosteroids on the efficacy of immunotherapy needs to be clarified.

The advances in molecular biology and the emergence of Next Generation Sequencing (NGS) have revealed that microbiome composition is closely related with health and disease, including cancer. This relationship affects different levels of cancer such as development, progression, and response to treatment including immunotherapy. The efficacy of immune checkpoint inhibitors (ICIs) may be influenced by the concomitant use of antibiotics before, during or shortly after treatment with ICIs. Nevertheless, the linking mechanism between microbiote, host immunity and cancer is not clear and the role of microbiota manipulation and analyses in cancer management has not been clinically validated yet. Regarding the use of microbiome as biomarker to predict ICI efficacy it has been recently shown that the use of biochemical serum markers to monitor intestinal permeability and loss of barrier integrity, like citrulline, could be useful to monitor microbiota changes and predict ICI efficacy. There are still many unknowns about the role of these components, their relationship with the microbiota, with the use of antibiotics and the response to immunotherapy. The next challenge in microbiome research will be to identify individual microbial species that causally affect lung cancer phenotypes and response to ICI and disentangle the underlying mechanisms. Thus, further analyses in patients with lung cancer receiving treatment with ICIs and its correlation with the composition of the microbiota in different organs including the respiratory tract, peripheral blood and intestinal tract could be useful to predict the efficacy of ICIs and its modulation with antibiotic use.
ABSTRACT
Despite therapeutic advances, lung cancer (LC) is one of the leading causes of cancer morbidity and mortality worldwide. Recently, the treatment of advanced LC has experienced important changes in survival benefit due to immune checkpoint inhibitors (ICIs). However, overall response rates (ORR) remain low in unselected patients and a large proportion of patients undergo disease progression in the first weeks of treatment. Therefore, there is a need of biomarkers to identify patients who will benefit from ICIs. The programmed cell death ligand 1 (PD-L1) expression has been the first biomarker developed. However, its use as a robust predictive biomarker has been limited due to the variability of techniques used, with different antibodies and thresholds. In this context, tumor mutational burden (TMB) has emerged as an additional powerful biomarker based on the observation of successful response to ICIs in solid tumors with high TMB. TMB can be defined as the total number of nonsynonymous mutations per DNA megabases being a mechanism generating neoantigens conditioning the tumor immunogenicity and response to ICIs. However, the latest data provide conflicting results regarding its role as a biomarker. Moreover, considering the results of the recent data, the use of peripheral blood T cell receptor (TCR) repertoire could be a new predictive biomarker. This review summarises recent findings describing the clinical utility of TMB and TCRß (TCRB) and concludes that immune, neontigen, and checkpoint targeted variables are required in combination for accurately identifying patients who most likely will benefit of ICIs.
ABSTRACT
The molecular and cell determinants that modulate immune checkpoint (ICI) efficacy in lung cancer are still not well understood. However, there is a necessity to select those patients that will most benefit from these new treatments. Recent studies suggest the presence and/or the relative balance of specific lymphoid cells in the tumor microenvironment (TEM) including the T cell (activated, memory, and regulatory) and NK cell (CD56dim/bright) subsets, and correlate with a better response to ICI. The analyses of these cell subsets in peripheral blood, as a more accessible and homogeneous sample, might facilitate clinical decisions concerning fast prediction of ICI efficacy. Despite recent studies suggesting that lymphoid circulating cells might correlate with ICI efficacy and toxicity, more analyses and investigation are required to confirm if circulating lymphoid cells are a relevant picture of the lung TME and could be instrumental as ICI response biomarkers. This short review is aimed to discuss the recent advances in this fast-growing field.
