[Impact of new nicotine delivery devices on smoking trends consumption and health].

The use of electronic cigarettes and heated tobacco products is increasing among adolescents and young adults. Tobacco companies offer these devices to enhance the smoking experience by magnifying its attractive and minimizing the negatives associated with the consumption of conventional cigarettes. The objective of this review is to update the available knowledge on the impact of these devices, both from an individual perspective, in terms of their effects on health, and from a public health perspective due to direct exposure and the effects derived from the second and third hand emissions.

Recommendations for the management of cutaneous squamous cell carcinoma: a systematic multidisciplinary Delphi consensus approach.

Background: There are gaps and unanswered questions in clinical guidelines regarding several aspects of the management of patients with cutaneous squamous cell carcinoma (cSCC).

Methods: A scientific committee of ten cSCC specialists in Spain (dermatology, medical oncology, oral and maxillofacial surgery, plastic surgery, and radiotherapy) used ADAPTE methodology to develop recommendations by: (i) identifying clinical questions not fully answered by clinical practice guidelines; (ii) systematically reviewing the literature (published between November 2017 and July 2023 in PubMed and the Cochrane database) and grading the evidence (using Oxford levels); (iii) developing recommendations and assessing those with no consensus among the scientific committee or with evidence level 3-5 or strength of recommendation under C or D in a two-round Delphi method; and (iv) developing the final recommendations in the form of answers to key clinical questions, grading the strength of recommendation. An external group of 32 experts plus the members of the committee participated in both Delphi rounds, evaluating the appropriateness and need of the recommendations.

Background/objectives: Patients with relapsed/refractory (R/R) AML with mutation () have a dismal prognosis. offers a target for therapy in these patients. Gilteritinib (gilter) and quizartinib (quizar) have demonstrated efficacy as single agents in two phase 3 clinical trials.

Unraveling the Genetic Heterogeneity of Acute Lymphoblastic Leukemia Based on NGS Applications.

Acute lymphoblastic leukemia (ALL) is a hematological neoplasm characterized by the clonal expansion of abnormal lymphoid precursors in bone marrow, which leads to alterations in the processes of cell differentiation and maturation as a consequence of genetic alterations. The integration of conventional methods, such as cytogenetics and immunophenotyping, and next-generation sequencing (NGS) has led to significant improvements at diagnosis and patient stratification; this has also allowed the discovery of several novel molecular entities with specific genetic variants that may drive the processes of leukemogenesis. Nevertheless, the understanding of the process of leukemogenesis remains a challenge since this disease persists as the most frequent cancer in children; it accounts for approximately one-quarter of adult acute leukemias, and the patient management may take into consideration the high intra- and inter-tumor heterogeneity and the relapse risk due to the various molecular events that can occur during clonal evolution.

High-risk cytogenetic abnormalities in multiple myeloma: PETHEMA-GEM experience.

This study examines the impact of cytogenetic abnormalities and their co-segregation on the prognosis of newly diagnosed multiple myeloma patients. The analysis included 1304 patients from four different GEM-PETHEMA clinical trials. Genetic alterations, such as t(4;14), t(14;16), del(17p), +1q, and del(1p), were investigated using FISH on CD38 purified plasma cells.

Ruxolitinib in acute and chronic graft-versus-host disease: real life long-term experience in a multi-center study for adult and pediatric patients, on behalf of the GETH-TC.

Ruxolitinib has been approved for the treatment of adults and pediatric patients ≥12 years with steroid refractory graft-versus-host disease (GvHD). However, real-life studies are needed to confirm the results of clinical trials and further assess its efficacy in special populations. We performed a descriptive, retrospective, multi-center study of 352 adults and 42 pediatric patients treated with ruxolitinib for steroid-refractory acute or chronic GvHD.

Impact of intensive versus nonintensive antithrombotic treatment on device-related thrombus after left atrial appendage closure.

Introduction And Objectives: The optimal antithrombotic therapy (AT) after left atrial appendage closure (LAAC) is debated. We assessed the impact of intensive vs nonintensive AT on the incidence of device-related thrombus (DRT) based on whether the device implantation was classified as optimal or suboptimal.

Methods: This study included patients who underwent successful LAAC in 9 centers.

Spanish Working Group in Crohn´s disease and ulcerative colitis (GETECCU) position paper on cardiovascular disease in patients with inflammatory bowel disease.

Cardiovascular diseases (CVD) are the leading cause of death worldwide. Therefore, it is essential to understand their relationship and prevalence in different diseases that may present specific risk factors for them. The objective of this document is to analyze the specific prevalence of CVD in patients with inflammatory bowel disease (IBD), describing the presence of classical and non-classical cardiovascular risk factors in these patients.

[Use of clinical ultrasound in primary care: Cardiovascular risk].

From primary care we work on the prevention and treatment of cardiovascular risk in our patients. The physical examination, the electrocardiogram and the analysis are the classic parameters and continue being the most efficient way to estimate the presence and control of cardiovascular factors and target organ damage, to optimize the cardiovascular risk stratification. The use of ultrasound by the primary care doctor to complete the clinical information is a reality that helps to strengthen the diagnostic suspicion, monitorize the clinical evolution and even decide the best therapeutic plan.

Native RNA nanopore sequencing reveals antibiotic-induced loss of rRNA modifications in the A- and P-sites.

The biological relevance and dynamics of mRNA modifications have been extensively studied; however, whether rRNA modifications are dynamically regulated, and under which conditions, remains unclear. Here, we systematically characterize bacterial rRNA modifications upon exposure to diverse antibiotics using native RNA nanopore sequencing. To identify significant rRNA modification changes, we develop NanoConsensus, a novel pipeline that is robust across RNA modification types, stoichiometries and coverage, with very low false positive rates, outperforming all individual algorithms tested.

Association between cigarette smoking, genetic polymorphism and myelodysplasia: a multicentric case-control study.

Background: Both cigarette smoking (CGS), through its role as a benzene source, and some metabolic detoxyfiying enzymes (EDTOX) polymorphisms that hamper its inactivation, are considered as risk factors for the development of myelodysplastic neoplasms (MDS) and related disorders. This study aims to confirm such associations.

Patients And Methods: We recruited 61 patients diagnosed with MDS following FAB Group criteria and 180 adults without peripheral blood cytopenia, and we analyzed: i) the crude odds-ratio (OR) for MDS between smokers and non-smokers, ii) the crude OR for MDS between homozygous individuals for the mutation NQO1C-T, or harboring deletions in the genes codyfing for GSTM1 y GSTT1, and those who did not show such genotypes, and iii) the OR for MDS between smokers and non-smokers, adjusted for other potential risk factors.

Clinical impact of [18F]FDG-PET/CT in ARI0002h treatment, a CAR-T against BCMA for relapsed/refractory multiple myeloma.

Multiple myeloma (MM) remains incurable, with poor outcomes in heavily pre-treated patients with plasmacytomas. Chimeric antigen receptor (CAR) T-cell therapy has emerged as a promising treatment option; however, outcomes after such therapy in patients with soft-tissue plasmacytomas and other bone lesions remain poorly understood. Data regarding these parameters is scarce within the specific context of CAR T-cell treatment.

Novel Gene Biomarkers Specific to Human Mesenchymal Stem Cells Isolated from Bone Marrow.

In this paper, we present a comparative analysis of the transcriptomic profile of three different human cell types: hematopoietic stem cells (HSCs), bone marrow-derived mesenchymal stem cells (MSCs) and fibroblasts (FIBs). The work aims to identify unique genes that are differentially expressed as specific markers of bone marrow-derived MSCs, and to achieve this undertakes a detailed analysis of three independent datasets that include quantification of the global gene expression profiles of three primary cell types: HSCs, MSCs and FIBs. A robust bioinformatics method, called , is used to assess the specific association between one or more genes expressed in a sample and the outcome variable, that is, the 'cell type' provided as a single univariate response.

Healthcare Costs of Hospitalizations Due to Aspergillosis and 25-Year Trends in Spain, 1997-2021.

In the last 40 years, a significant increase in the incidence of lung infections by Aspergillus has been reported. The scarcity of studies that describe the costs of aspergillosis indicates that the economic impact of aspergillosis in the hospital environment is greater than that of other fungal infections. The objective of the study was to evaluate the direct healthcare costs associated with aspergillosis in the Spanish National Health System from 1997 to 2021.
