Abstract
PURPOSE OF REVIEW This review addresses the emerging role of antibody-drug conjugates (ADCs) in the treatment of ovarian cancer, a field marked by a high need for more effective and targeted therapies. Given the recent advancements in ADC technology and the ongoing challenges in treating ovarian cancer, particularly in late-stage and recurrent cases, this review is both timely and relevant. It synthesizes current research findings and clinical trial data, highlighting the potential of ADCs to revolutionize ovarian cancer treatment. RECENT FINDINGS The review covers key themes including the mechanism of action of ADCs, their specificity in targeting ovarian cancer cells, recent clinical trial outcomes, advancements in ADC design for improved efficacy and reduced toxicity, and strategies to overcome drug resistance in ovarian cancer. It also addresses the heterogeneity of ovarian cancer and the implications for personalized ADC therapies. SUMMARY The review underscores the potential of ADCs to significantly impact clinical practice, offering a more effective and personalized treatment approach for ovarian cancer patients. The review suggests a paradigm shift in the treatment of this malignancy, emphasizing the need for further research and development in this area.

Abstract
Newborn screening for cystic fibrosis (CF) can identify affected but asymptomatic infants. The selection of omic technique for gut microbiota study is crucial due to both the small amount of feces available and the low microorganism load. Our aims were to compare the agreement between 16S rRNA amplicon sequencing and metaproteomics by a robust statistical analysis, including both presence and abundance of taxa, to describe the sequential establishment of the gut microbiota during the first year of life in a small size sample (8 infants and 28 fecal samples). The taxonomic assignations by the two techniques were similar, whereas certain discrepancies were observed in the abundance detection, mostly the lower predicted relative abundance of Bifidobacterium and the higher predicted relative abundance of certain Firmicutes and Proteobacteria by amplicon sequencing. During the first months of life, the CF gut microbiota is characterized by a significant enrichment of Ruminococcus gnavus, the expression of certain virulent bacterial traits, and the detection of human inflammation-related proteins. Metaproteomics provides information on composition and functionality, as well as data on host-microbiome interactions. Its strength is the identification and quantification of Actinobacteria and certain classes of Firmicutes, but alpha diversity indices are not comparable to those of amplicon sequencing. Both techniques detected an aberrant microbiota in our small cohort of infants with CF during their first year of life, dominated by the enrichment of R. gnavus within a human inflammatory environment. IMPORTANCE In recent years, some techniques have been incorporated for the study of microbial ecosystems, being 16S rRNA gene sequencing being the most widely used. Metaproteomics provides the advantage of identifying the interaction between microorganisms and human cells, but the available databases are less extensive as well as imprecise. Few studies compare the statistical differences between the two techniques to define the composition of an ecosystem. Our work shows that the two methods are comparable in terms of microorganism identification but provide different results in alpha diversity analysis. On the other hand, we have studied newborns with cystic fibrosis, for whom we have described the establishment of an intestinal ecosystem marked by the inflammatory response of the host and the enrichment of Ruminococcus gnavus.

Abstract
Human gut microbiota can be studied through the characterization of microorganisms present in feces. Metaproteomics has arisen as a good approach to investigate this vast community. However, the processing of fecal samples in order to obtain the largest number of proteins from gut microbiota to be subsequently analyzed by means of metaproteomics is a challenge. Here we describe a protocol to approach this task. It includes two main steps: the first step of humectation and dispersion of the feces, followed by the separation of microorganisms from other fecal components such as roughage and food debris, and the second step in which microbial cells are broken up and microbiota proteins recovered for MS analysis. Detailed procedures for sample preparation, protein extraction, trypsin digestion, and mass spectrometry analysis for gut microbiota samples are provided.

Abstract
The use of metaproteomics for studying the human gut microbiota can shed light on the taxonomic profile and the functional role of the microbial community. Nevertheless, methods for extracting proteins from stool samples continue to evolve, in the pursuit of optimal protocols for moistening and dispersing the stool sample and for disrupting microbial cells, which are two critical steps for ensuring good protein recovery. Here, we evaluated different stool sample processing (SSP) and microbial cell disruption methods (CDMs). The combination of a longer disintegration period of the stool sample in a tube rotator with sonication increased the overall number of identified peptides and proteins. Proteobacteria, Bacteroidetes, Planctomycetes, and Euryarchaeota identification was favored by mechanical cell disruption with glass beads. In contrast, the relative abundance of Firmicutes, Actinobacteria, and Fusobacteria was improved when sonication was performed before bead beating. Tenericutes and Apicomplexa identification was enhanced by moistening the stool samples during processing and by disrupting cells with medium-sized glass beads combined with or without sonication. Human protein identifications were affected by sonication. To test the reproducibility of these gut metaproteomic analyses, we examined samples from six healthy individuals using a protocol that had shown a good taxonomic diversity and identification of proteins from Proteobacteria and humans. We also detected proteins involved in microbial functions relevant to the host and related mostly to specific taxa, such as B12 biosynthesis and short chain fatty acid (SCFA) production carried out mainly by members in the Prevotella genus and the Firmicutes phylum, respectively. The taxonomic and functional profiles obtained with the different protocols described in this work provides the researcher with valuable information when choosing the most adequate protocol for the study of certain pathologies under suspicion of being related to a specific taxon from the gut microbiota.

Abstract
Las luxaciones puras de las articulaciones digitales durante el período de maduración esquelética son de presentación excepcional, dado que habitualmente las lesiones traumáticas a este nivel se presentan en forma de fracturas-luxaciones con afectación de la epífisis, debido a que su resistencia mecánica ante el traumatismo es menor que la de los propios ligamentos. Revisamos en este artículo nuestros casos de luxaciones digitales puras en niños y adolescentes y la literatura más relevante sobre las mismas.

Abstract
El quiste óseo aneurismático es una lesión tumoral benigna poco frecuente y que raras veces afecta a los huesos de la mano.Se presentan dos casos en niños, de afectación de los metacarpianos, que fueron tratados mediante resección de la lesión en bloque del metacarpiano, y reconstrucción con autoinjerto libre de peroné. Se obtuvo un buen resultado funcional sin recidiva a los seis y dos años respectivamente. No hubo morbilidad reseñable en la zona donante.
