Performance of a Shotgun Prediction Model for Colorectal Cancer When Using 16S rRNA Sequencing Data
Colorectal cancer (CRC), the third most common cancer globally, has shown links to disturbed gut microbiota. While significant efforts have been made to establish a microbial signature indicative of CRC using shotgun metagenomic sequencing, the challenge lies in validating this signature with 16S ribosomal RNA (16S) gene sequencing. The primary obstacle is reconciling the differing outputs of these two methodologies, which often lead to divergent statistical models and conclusions. In this study, we introduce an algorithm designed to bridge this gap by mapping shotgun-derived taxa to their 16S counterparts. This mapping enables us to assess the predictive performance of a shotgun-based microbiome signature using 16S data. Our results demonstrate a reduction in performance when applying the 16S-mapped taxa in the shotgun prediction model, though it retains statistical significance. This suggests that while an exact match between shotgun and 16S data may not yet be feasible, our approach provides a viable method for comparative analysis and validation in the context of CRC-associated microbiome research

Nomophobia in university students during COVID-19 outbreak: a cross-sectional study
Introduction: Currently, access to the Internet through smartphones has led to their functions going beyond purely communicative ones, allowing the management of massive, instantaneous, and easily accessible information. This research analyzed the differences in smartphone use and the prevalence of nomophobia, mainly according to gender and university degree of Health Sciences students at the University of Zaragoza during the COVID-19 confinement in Spain. Methods: A descriptive cross-sectional study was carried out on a sample of 318 first and second-grade students, who completed an online questionnaire sent to their institutional email, which included sociodemographic questions, other questions about smartphone use, and the Nomophobia Questionnaire (NMP-Q) scale. Results: Compared to men (n = 58), women (n = 260) were more likely to use their smartphones more intensively daily, as were occupational therapy students compared to the other degree programs studied. The prevalence of nomophobia was moderate, being around the risk of suffering from it. No significant differences in scores for nomophobia among students were found according to gender, university degree, or population nucleus for the nomophobia scores of the students. Discussion: The present study extends the existing literature on nomophobia by providing results of interest in terms of gender and the exceptional healthcare context of COVID-19. The results suggest that despite intense daily smartphone use young people did not reach severe nomophobia figures. This fact underlines the need for appropriate and healthy technology education. Understanding the characteristics of the populations that use the smartphone the most may help to analyze nomophobia rates and the massive use of the device
Selective targeting of collagen IV in the cancer cell microenvironment reduces tumor burden
Goodpasture antigen-binding protein (GPBP) is an exportable1 Ser/Thr kinase
that induces collagen IV expansion and has been associated with chemoresistance
following epithelial-to-mesenchymal transition (EMT). Here we demonstrate that
cancer EMT phenotypes secrete GPBP (mesenchymal GPBP) which displays a
predominant multimeric oligomerization and directs the formation of previously
unrecognized mesh collagen IV networks (mesenchymal collagen IV). Yeast twohybrid
(YTH) system was used to identify a 260SHCIE264 motif critical for multimeric
GPBP assembly which then facilitated design of a series of potential peptidomimetics.
The compound 3-[4''-methoxy-3,2'-dimethyl-(1,1';4',1'')terphenyl-2''-yl]propionic
acid, or T12, specifically targets mesenchymal GPBP and disturbs its multimerization
without affecting kinase catalytic site. Importantly, T12 reduces growth and
metastases of tumors populated by EMT phenotypes. Moreover, low-dose doxorubicin
sensitizes epithelial cancer precursor cells to T12, thereby further reducing tumor
load. Given that T12 targets the pathogenic mesenchymal GPBP, it does not bind
significantly to normal tissues and therapeutic dosing was not associated with
toxicity. T12 is a first-in-class drug candidate to treat cancer by selectively targeting
the collagen IV of the tumor cell microenvironment.This work was supported by grants: PET 2006_0721, TRA2009_0026, IPT-010000-2010-45, IPT-2011-1527- 010000, RTC-2014-2415-1, PCB-010000-2010-031, PCB- 010000-2010-032, EQU-2014-1-0301 of the Plan Nacional de Investigación, Desarrollo e Innovación of the Spanish Government and IMGESA/06/78, IMGESA/06/79 of Conselleria d’Empresa, Universitat i Ciencia of Generalitat Valenciana to Fibrostatin, S.L. and J.S.; SAF 2001/0453, SAF 2003-09772-C03-01, SAF 2006-12520-C02-01, SAF 2009-10703 of the Plan Nacional de Investigación, Desarrollo e Innovación of the Spanish Government and PROMETEO/2009/065, PROMETEOII/2014/048 of Conselleria de Educaciò of Generalitat Valenciana to J.S.

Analysis of the Attitudes towards Sexuality in People with Intellectual Disabilities: A Cross-Sectional Study
The barriers faced by people with intellectual disabilities are many. One of the areas in which many problems have been identified is the sexual domain. This descriptive study aims to analyze the attitudes of the family environment, professional carers, and the general population toward their sexuality. A cross-sectional descriptive study was carried out between 2022 and 2023, using convenience sampling among family members and carers from different centers working with people with intellectual disabilities in Spain, and among the general population not related to people with intellectual disabilities. A total of 583 responses were received and significant differences were found for all variables, with the variables related to family or work proximity being those that provided the most significant and relevant results. It was observed that the male sex has a more paternalistic attitude and that in rural areas there is a more permissive attitude towards the sexuality of people with intellectual disabilities. People who work with people with disabilities have more positive attitudes towards this group, while direct relatives have more paternalistic attitudes. Nursing care in the community and specialized centers should be based on an adequate therapeutic relationship and personalized care
ADHD symptomatology in eating disorders : a secondary psychopathological measure of severity?
Background: Attention-deficit/hyperactivity disorder (ADHD) has commonly been described in psychiatric disorders. Although several studies have found positive associations between abnormal eating patterns during childhood and ADHD, there is a lack of studies on ADHD and Eating Disorders (ED). The aims of this exploratory study were 1) to assess the ADHD symptoms level in ED and to ascertain whether there are differences among ED subtypes; 2) to analyze whether the presence of ADHD symptoms is associated with more severe eating disorder symptoms and greater general psychopathology; and 3) to assess whether the ADHD symptoms level is associated with specific temperament and character traits. Methods: 191 female ED patients were included. Assessment was carried out with the EDI-2, ASRS-v1.1, the SCL-90-R and the TCI-R. Results: The ADHD symptoms level was similar in bulimia, eating disorder not otherwise specified and binge eating subtypes, and lower in anorexic patients. Obsessiveness and Hostility were significantly positively associated with ADHD symptoms. A path model showed that ADHD was associated with high Novelty Seeking and low Self-Directedness, whereas ED severity was influenced by ADHD severity and low Self-Directedness. Conclusions: Bingeing/purging ED subtypes have a high ADHD symptoms level, also related with more severe eating, general and personality psychopathology

SARS-CoV-2-reactive antibody detection after SARS-CoV-2 vaccination in hematopoietic stem cell transplant recipients: Prospective survey from the Spanish Hematopoietic Stem Cell Transplantation and Cell Therapy Group
This is a multicenter prospective observational study that included a large cohort (n = 397) of allogeneic (allo-HSCT; (n = 311) and autologous (ASCT) hematopoietic stem cell transplant (n = 86) recipients who were monitored for antibody detection within 3–6 weeks after complete severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination from February 1, 2021, to July 20, 2021. Most patients (n = 387, 97.4%) received mRNA-based vaccines. Most of the recipients (93%) were vaccinated more than 1 year after transplant. Detectable SARS-CoV-2-reactive antibodies were observed in 242 (78%) of allo-HSCT and in 73 (85%) of ASCT recipients. Multivariate analysis in allo-HSCT recipients identified lymphopenia < 1 × 109/ml (odds ratio [OR] 0.33, 95% confidence interval [95% CI] 0.16–0.69, p = .003), active graft versus host disease (GvHD; OR 0.51, 95% CI 0.27–0.98, p = .04) and vaccination within the first year of transplant (OR 0.3, 95% CI 0.15–0.9, p = .04) associated with lower antibody detection whereas. In ASCT, non-Hodgkin's lymphoma (NHL; OR 0.09, 95% CI 0.02–0.44, p = .003) and active corticosteroid therapy (OR 0.2, 95% CI 0.02–0.87, p = .03) were associated with lower detection rate. We report an encouraging rate of SARS-CoV-2-reactive antibodies detection in these severe immunocompromised patients. Lymphopenia, GvHD, the timing of vaccine, and NHL and corticosteroids therapy should be considered in allo-HSCT and ASCT, respectively, to identify candidates for SARS-CoV-2 antibodies monitoring.Peer reviewe
