Deciphering taxonomic and functional patterns of microbial communities associated with the tiger tail seahorse (Hippocampus comes).

Gaining insight into the diversity, structure, and metabolic functions of microbial communities is essential for understanding their roles in host health and ecosystem dynamics. However, research on the seahorse-associated microbiome remains limited, despite these threatened fish facing increasing human pressures worldwide. Here, we explored the microbial diversity and metabolic functions of the skin and gut of the tiger tail seahorse (Hippocampus comes) and its surrounding environment using shotgun metagenomics and bioinformatics. Members of the Pseudomonadota phylum were dominant in the skin microbiome, whereas Bacteroidota was dominant in the gut. Bacillota, Actinomycetota, and Planctomycetota were also detected in the seahorse-associated microbiome. Statistical analysis revealed significant differences (p<0.01) in species diversity between skin and gut microbiomes, with members belonging to the Moraxellaceae family being dominant on the skin and the Bacteroidaceae family in the gut. Moreover, the surrounding environment (water or sediment) did not have a direct effect on the seahorse microbiome composition. The skin microbiome exhibited a higher abundance of functional genes related to energy, lipid, amino acid metabolism, as well as terpenoids and polyketides metabolism, xenobiotics biodegradation and metabolism compared to the gut. Despite differences among classes, the total abundance of bacteriocins was similar in both gut and skin microbiomes, which is significant in shaping microbial communities due to their antimicrobial properties. A better knowledge of seahorse microbiomes benefits conservation and sustainable aquaculture efforts, offering insights into habitat protection, disease management, and optimizing aquaculture environments, thereby promoting seahorse health and welfare while minimizing environmental impact and enhancing aquaculture sustainability.

Evaluation and application of American College of Radiology Thyroid Imaging Reporting and Data System for improved malignancy detection in paediatric thyroid nodules.

OBJECTIVE: The American College of Radiology Thyroid Imaging Reporting and Data System (TI-RADS) is a widely used method for the management of adult thyroid nodules. However, its use in paediatric patients is controversial because adult fine needle aspiration biopsy (FNAB) recommendations may lead to delayed diagnoses of cancer in children. The objectives of this study were to evaluate the performance of TI-RADS in paediatric thyroid nodules and to tailor FNAB recommendations for children. METHODS: Consecutive surgically resected paediatric thyroid nodules from two tertiary care centres between 2003 and 2021 were reviewed. Ultrasounds were blindly scored by radiologists according to TI-RADS. Management recommendations based on TI-RADS were evaluated. Various modelling methodologies were used to determine the optimal cutoff for FNAB in children. RESULTS: Of the 96 patients, 79 (82%) were female and the median age at surgery was 16.1 years. Fifty (52%) nodules were malignant on surgical pathology. The area under the receiver operating characteristic curve of TI-RADS for predicting malignancy was 0.78. Adult TI-RADS recommendations would have resulted in 4% of cancerous nodules being lost to follow-up. Modifications to TI-RADS (FNAB of all TR3 nodules ≥1.5 cm, FNAB of TR4 and TR5 nodules ≥0.5 cm, surveillance of nodules ≥1 cm, consider surgery for nodules >4 cm) reduced this missed malignancy rate to 0%. CONCLUSIONS: TI-RADS can risk-stratify paediatric thyroid nodules. However, the system requires modifications to reduce the missed malignancy rate in paediatric thyroid nodules. Our data suggest that lower size thresholds for FNAB are warranted in children.

Long-term outcomes of the global tuberculosis and COVID-19 co-infection cohort.

BACKGROUND: Longitudinal cohort data of patients with tuberculosis (TB) and coronavirus disease 2019 (COVID-19) are lacking. In our global study, we describe long-term outcomes of patients affected by TB and COVID-19. METHODS: We collected data from 174 centres in 31 countries on all patients affected by COVID-19 and TB between 1 March 2020 and 30 September 2022. Patients were followed-up until cure, death or end of cohort time. All patients had TB and COVID-19; for analysis purposes, deaths were attributed to TB, COVID-19 or both. Survival analysis was performed using Cox proportional risk-regression models, and the log-rank test was used to compare survival and mortality attributed to TB, COVID-19 or both. RESULTS: Overall, 788 patients with COVID-19 and TB (active or sequelae) were recruited from 31 countries, and 10.8% (n=85) died during the observation period. Survival was significantly lower among patients whose death was attributed to TB and COVID-19 versus those dying because of either TB or COVID-19 alone (p<0.001). Significant adjusted risk factors for TB mortality were higher age (hazard ratio (HR) 1.05, 95% CI 1.03-1.07), HIV infection (HR 2.29, 95% CI 1.02-5.16) and invasive ventilation (HR 4.28, 95% CI 2.34-7.83). For COVID-19 mortality, the adjusted risks were higher age (HR 1.03, 95% CI 1.02-1.04), male sex (HR 2.21, 95% CI 1.24-3.91), oxygen requirement (HR 7.93, 95% CI 3.44-18.26) and invasive ventilation (HR 2.19, 95% CI 1.36-3.53). CONCLUSIONS: In our global cohort, death was the outcome in >10% of patients with TB and COVID-19. A range of demographic and clinical predictors are associated with adverse outcomes.

A Broad-Host-Range Phage Cocktail Selectively and Effectively Eliminates Vibrio Species from Shrimp Aquaculture Environment.

The protective effects of a phage cocktail composed of vB_Vc_SrVc2 and vB_Vc_SrVc9 were tested in Pacific white shrimp (Litopenaeus vannamei) postlarvae, which were originally isolated from diseased shrimps and selected due to their broad-host-range properties against several pathogenic Vibsrio species. We used culture-dependent and culture-independent approaches to explore its effect on bacterial communities associated with shrimp postlarvae. Both methods revealed that the levels of Vibrio species were significantly reduced after phage cocktail administration. Phage-treated shrimp also exhibisuppted lesser damage and higher lipid accumulation in B cells of the hepatopancreas, as revealed by histopathological examination. Taken together, this study provides clear evidence that phage therapy can selectively and effectively reduce Vibrio species, thereby providing an environmentally safe alternative to the prophylactic use of antibiotics in shrimp aquaculture.

Skin-to-skin contact in mothers with suspected, probable, or confirmed COVID-19.

BACKGROUND: The World Health Organization recommends skin-to-skin contact (SSC) in newborns of mothers with COVID-19, applying infection prevention and control measures, and after a process of antenatal counseling on the possible risks and benefits. In this study, the reasons given for and against postnatal SSC in mothers with COVID-19 were reviewed. METHOD: Between November and December 2020, we conducted a scoping review. Twenty-six relevant studies were identified. The results were extracted and presented narratively. RESULTS: The reasons described for avoiding SSC have include contradictory recommendations, risk of virus transmission, impossibility of universal antepartum maternal screening for COVID-19, work overload, and ethical considerations. The reasons given for the maintenance of SSC include maternal and infant benefits of SSC, previous experiences in viral outbreaks, protection of newborns against infections, decreased contact with professionals, caregivers and surfaces, and preservation of natural processes. CONCLUSIONS: The recommendation to allow SSC is based primarily on the acceptance that horizontal perinatal transmission is unlikely if correct hygiene precautions are taken and that the benefits of SSC outweigh the potential risks of neonatal COVID-19 infection. Knowing the reasons that have motivated the current recommendations on SSC is essential to be able to carry out an effective prenatal parental education that allows a shared decision to be made.

Factors Associated With Resilience During Long-Term Hemodialysis.

BACKGROUND: Resilience has been associated with greater adherence to treatment, better outcomes, and improved quality of life (QOL) in people with chronic health conditions. This study aimed to identify sociodemographic, treatment accessibility-related, clinical, and psychological variables associated with resilience in patients with advanced chronic kidney disease (CKD) undergoing long-term hemodialysis (>6 months). METHODS: This was a multicenter, cross-sectional, and correlational study. The instruments used were the Spanish versions of the Connor-Davidson Resilience Scale, the Perceived Stress Scale-10, and the Kidney Disease Quality of Life-36. The participants were categorized as resilient (with a score of ≥49.37 on the Connor-Davidson Resilience Scale) or nonresilient. Binary logistic regression analysis was performed to identify variables with predictive power for the group with the resilient profile. RESULTS: Perceived stress, general QOL, and subcomponents of QOL, such as the physical component and burden of kidney disease, were identified as factors related to the resilient profile. DISCUSSION: Identifying the factors related to resilient adjustment in patients with advanced CKD may assist health caregivers in improving adherence to treatment, treatment outcomes, and QOL.

Leveraging the virtual landscape to promote diversity, equity, and inclusion in Otolaryngology-Head & Neck Surgery.

The pandemic era has wrought disruptive changes across all aspects of academic medicine, transforming clinical care systems, research enterprises, and educational practices. Among these sweeping changes, some of the most significant for Otolaryngology-Head & Neck Surgery (OHNS) relate to innovative use of virtual communication. The virtual landscape has not only redefined the delivery of patient care but also expanded educational interactions across the career continuum. As the architecture of relationships has been reimagined, the traditional Halstedian teaching paradigm has evolved, now integrating in-person, virtual, and hybrid learning. Once formidable barriers to distance learning have diminished, giving way to social networks that support mentorship, coaching, and sponsorship. Creative use of technology supports collaboration, feedback, spaced learning, scaffolding, and interleaving. These advances have immediate significance for OHNS, a highly collaborative specialty that leads in technological innovation and aspires to improve diversity. Whereas traditional efforts to grow the ranks of underrepresented in medicine (URiM) individuals in OHNS yielded only incremental progress, the virtual landscape is unveiling new strategies for reengineering narrow or leaky pipelines. Strategies that can help attract URiM applicants include inclusive departmental web presence, interactive online clinical experiences, virtual interviews, and remote research opportunities. As students, surgeons, and scientists collectively embrace technology, accelerated progress toward diversity, equity, and inclusion (DEI) becomes possible. Maximizing these opportunities requires aligning national and institutional imperatives for diversity with departmental priorities and mission. Finally, intentional outreach and holistic assessment support growth of structured virtual communities that foster equitable access for those who need it most.

Towards Real-Time Hyperspectral Multi-Image Super-Resolution Reconstruction Applied to Histological Samples.

Hyperspectral Imaging (HSI) is increasingly adopted in medical applications for the usefulness of understanding the spectral signature of specific organic and non-organic elements. The acquisition of such images is a complex task, and the commercial sensors that can measure such images is scarce down to the point that some of them have limited spatial resolution in the bands of interest. This work proposes an approach to enhance the spatial resolution of hyperspectral histology samples using super-resolution. As the data volume associated to HSI has always been an inconvenience for the image processing in practical terms, this work proposes a relatively low computationally intensive algorithm. Using multiple images of the same scene taken in a controlled environment (hyperspectral microscopic system) with sub-pixel shifts between them, the proposed algorithm can effectively enhance the spatial resolution of the sensor while maintaining the spectral signature of the pixels, competing in performance with other state-of-the-art super-resolution techniques, and paving the way towards its use in real-time applications.

Classification, prevalence, and outcomes of anticancer therapy-induced cardiotoxicity: the CARDIOTOX registry.

AIM: Cardiotoxicity (CTox) is a major side effect of cancer therapies, but uniform diagnostic criteria to guide clinical and research practices are lacking. METHODS AND RESULTS: We prospectively studied 865 patients, aged 54.7 ± 13.9; 16.3% men, scheduled for anticancer therapy related with moderate/high CTox risk. Four groups of progressive myocardial damage/dysfunction were considered according to current guidelines: normal, normal biomarkers (high-sensitivity troponin T and N-terminal natriuretic pro-peptide), and left ventricular (LV) function; mild, abnormal biomarkers, and/or LV dysfunction (LVD) maintaining an LV ejection fraction (LVEF) ≥50%; moderate, LVD with LVEF 40-49%; and severe, LVD with LVEF ≤40% or symptomatic heart failure. Cardiotoxicity was defined as new or worsening of myocardial damage/ventricular function from baseline during follow-up. Patients were followed for a median of 24 months. Cardiotoxicity was identified in 37.5% patients during follow-up [95% confidence interval (CI) 34.22-40.8%], 31.6% with mild, 2.8% moderate, and 3.1% with severe myocardial damage/dysfunction. The mortality rate in the severe CTox group was 22.9 deaths per 100 patients-year vs. 2.3 deaths per 100 patients-year in the rest of groups, hazard ratio of 10.2 (95% CI 5.5-19.2) (P < 0.001). CONCLUSIONS: The majority of patients present objective data of myocardial injury/dysfunction during or after cancer therapy. Nevertheless, severe CTox, with a strong prognostic relationship, was comparatively rare. This should be reflected in protocols for clinical and research practices.

Observer-Based Time-Variant Spacing Policy for a Platoon of Non-Holonomic Mobile Robots.

This paper presents a navigation strategy for a platoon of n non-holonomic mobile robots with a time-varying spacing policy between each pair of successive robots at the platoon, such that a safe trailing distance is maintained at any speed, avoiding the robots getting too close to each other. It is intended that all the vehicles in the formation follow the trajectory described by the leader robot, which is generated by bounded input velocities. To establish a chain formation among the vehicles, it is required that, for each pair of successive vehicles, the (i+1)-th one follows the trajectory executed by the former i-th one, with a delay of τ(t) units of time. An observer is proposed to estimate the trajectory, velocities, and positions of the i-th vehicle, delayed τ(t) units of time, consequently generating the desired path for the (i+1)-th vehicle, avoiding numerical approximations of the velocities, rendering robustness against noise and corrupted or missing data as well as to external disturbances. Besides the time-varying gap, a constant-time gap is used to get a secure trailing distance between each two successive robots. The presented platoon formation strategy is analyzed and proven by using Lyapunov theory, concluding asymptotic convergence for the posture tracking between the (i+1)-th robot and the virtual reference provided by the observer that corresponds to the i-th robot. The strategy is evaluated by numerical simulations and real-time experiments.

Prevalence of Myofascial Pain Syndrome in Chronic Non-Specific Neck Pain: A Population-Based Cross-Sectional Descriptive Study.

BACKGROUND: Chronic non-specific neck pain is a frequent complaint. It is a recognized medical and socioeconomic problem and a frequent cause of job absenteeism. In recent years, case reports about myofascial pain syndrome (MPS) are emerging among patients suffering from pain. MPS is a regional pain syndrome characterized by myofascial trigger points (MTrP) in palpable taut bands of skeletal muscle that refer pain to a distance, and that can cause distant motor and autonomic effects. OBJECTIVE: To assess the prevalence of active and latent MTrPs in subjects suffering from chronic non-specific neck pain. DESIGN: A population-based cross-sectional descriptive study was carried out from January 2012 to December 2014. SETTING: Three primary healthcare centers in Alcalá de Henares, Madrid (Spain). SUBJECTS: Two hundred and twenty-four participants diagnosed by their family doctor with chronic non-specific neck pain. METHODS: Participants were examined by a physical therapist to determine the presence of MPS. Pain descriptions from the subjects and pain body diagrams guided the physical examination. The subjects were not given any information concerning MPS or other muscle pain syndromes. RESULTS: All participants presented with MPS. MTrPs of the trapezius muscles were the most prevalent, in 93.75% of the participants. The most prevalent active MTrPs were located right (82.1%) and left (79%) in the nearly-horizontal fibers of the upper trapezius muscle. Furthermore, active MTrPs in the levator scapulae, multifidi, and splenius cervicis muscles reached a prevalence of 82.14%, 77.68%, and 62.5%, respectively. CONCLUSIONS: MPS is a common source of pain in subjects presenting chronic non-specific neck pain.

Dry needling of the trapezius muscle in office workers with neck pain: a randomized clinical trial.

BACKGROUND: Neck pain is a frequent complaint in office workers. This pain can be caused by myofascial trigger points (MTrPs) in the trapezius muscle. This study aimed to determine the effectiveness of deep dry needling (DDN) of active MTrPs in the trapezius muscle. METHODS: A randomized, single blinded clinical trial was carried out at the Physical Therapy Department at Physiotherapy in Women's Health Research Group at Physical Therapy Department of University of Alcalá, in Alcalá de Henares, Madrid, Spain. Forty-four office workers with neck pain and active MTrPs in the trapezius muscle were randomly allocated to either the DDN or the control group (CG). The participants in the DDN group were treated with DDN of all MTrPs found in the trapezius muscle. They also received passive stretch of the trapezius muscle. The CG received the same passive stretch of the trapezius muscle only. The primary outcome measure was subjective pain intensity, measured using a visual analogue scale (VAS). Secondary outcomes were pressure pain threshold (PPT), cervical range of motion (CROM) and muscle strength. Data were collected at baseline, after interventions and 15 days after the last treatment. RESULTS: Differences were found between the DDN group and the CG for the VAS (P < 0.001), PPT (P < 0.001), range of motion (AROM) (P < 0.05) and strength (P < 0.05) after intervention and at the 15-day follow-up. DISCUSSION: Deep dry needling and passive stretch seems to be more effective than passive stretch only. The effects are maintained in the short term. The results support the use of DDN in the management of trapezius muscle myofascial pain syndrome in neck pain.

Spanish cultural adaptation and validation of the shoulder pain and disability index, and the oxford shoulder score after breast cancer surgery.

BACKGROUND: The Oxford Shoulder Score (OSS) and the Shoulder Pain and Disability Index (SPADI) are patient-based outcome scores with valid psychometric properties which are widely used for shoulder interventions. OBJECTIVE: The purpose of the study is to adapt both questionnaires cross-culturally to Spanish, and to test their reliability, validity, responsiveness, and feasibility. DESIGN: Cultural adaptation and psychometric validation study. METHODS: Consecutive patients who had undergone breast cancer surgery referred to an outpatient clinic at the University of Alcalá de Henares, Spain. One hundred and twenty women who had undergone breast cancer surgery, with pain and shoulder dysfunction. Cross-cultural adaptation was performed according to the international guidelines. Reliability was analysed by test-retest reliability and internal consistency. Content and convergent construct validity were measured by the Expert Committee's and Spearman coefficient respectively. Responsiveness, feasibility, floor and ceiling effects were also tested. RESULTS: One hundred and twenty women aged 54.2 (±11) years took part in the study. The reliability was excellent; test-retest reliability was 0.974 (p < 0.001) for OSS, and 0.992 (p < 0.001) for SPADI; and Cronbach's alpha value was 0.947 for OSS, and 0.965 for SPADI. High construct validity was found between the OSS and SPADI questionnaires (r = -0.674). The effect size (ES) and standardized response mean (SRM) was moderate in OSS (ES = 0.50 and SRM = 0.70 (p < 0.001)), and moderate to good in SPADI (ES = 0.59 and SRM = 0.82 (p < 0.001)). LIMITATIONS: This study has some limitations, such as the group of participants is composed only of women following breast cancer treatment; the measurement took place in a single centre; and all the questionnaires administered were always provided to the participants in the same order. CONCLUSIONS: The OSS and SPADI Spanish versions are applicable, reliable, valid, and responsive to assess shoulder symptoms and quality of life in Spanish women with shoulder pain and disability after breast cancer treatment.

Patient-centred communication in British, Italian and Spanish 'Ask-the-Expert' healthcare websites.

Existing studies on the online asynchronous consultation mode afforded by 'Ask-the-Expert' health websites (e.g. Thomson et al. 2012) are concerned with the possible loss in the quality of interaction between patients and clinicians in this type of consultation. The potential loss is worrying, given the central role of patient-centred communication (PCC), particularly empathy, in medical consultation practice and patients' increasing use of and reliance on online consultations. This study addresses the following three related questions: (1) To what extent is PCC represented in 'Ask-the-Expert' healthcare websites? (2) Are there noticeable differences in PCC between sites operating in different linguistic and cultural settings (the UK, Spain and Italy)? (3) What are the implications of the above? Seventy exchanges from the leading independent health websites NetDoctor (UK), Netdoctor (Spain) and Medicitalia (Italy) were analysed, adapting a framework developed for the linguistic analysis of clinical empathy (combining discourse analytical and pragmatic categories ­ Pounds 2011) and drawing on existing definitions of PCC and classifications of advice-giving structures. The analysis shows that PCC is used on these sites to varying degrees, conforming to the site's affordances. The significance of the findings and potential further applications of the analytical framework are discussed in the final part.

[Sense of coherence in breastfeeding women: A scoping review].

BACKGROUND: The establishment of breastfeeding may sometimes be stressful. We aimed to analyze the sense of coherence in lactating women to determine the general resistance resources during lactation and the professional interventions that promote a high sense of coherence. METHODS: A search of studies in English, Spanish, or Portuguese on lactating women's sense of coherence was carried out in PubMed, PsycINFO, ScienceDirect, and CINAH databases published between May and November 2022. Study quality and risk of bias were examined according to ICROMS and STROBE criteria. RESULTS: We identified 316 studies, of which eight -all of adequate quality- were included, three qualitative and five quantitative. A high level of maternal sense of coherence was related to longer duration, self-efficacy, attachment, and enjoyment of the breastfeeding experience. The main general resistance resources were to receive social support, particularly from partners, mothers, and health professionals. The interventions that favored the sense of coherence were mainly those related to a close, empathic, personalized, comprehensive, and family-centered professional support. CONCLUSIONS: The detection of the level of sense of coherence in lactating mothers may help identify women with a higher risk of weaning and establish professional intervention strategies that improve the breastfeeding experience.

Why tRNA acquisition could be relevant to bacteriophages?

In this opinion, we discuss the role of tRNAs in phage biology and their importance in DNA replication and phage-host interactions. Phages are a diverse group of obligate bacterial viruses that possess genomes with a wide range of sizes. Among them, we find phages with few genes that depend entirely on their host's translational machinery for replication. However, some phages carry genes for all replication steps and even contain genes for their own translational synthesis. In these cases, the integration of tRNA genes in their genomes is not completely understood, generating different theories about their presence and function during the replication cycle. Although different studies have attempted to elucidate their role, additional studies are needed to clarify the presence and significance of tRNA genes in phages. Moreover, we highlight the importance of tRNA genes in phages from both ecological and therapeutic perspectives.

Citizen Science Studies in Nursing: A Systematic Review.

BACKGROUND: Citizen science is a research approach wherein citizens actively participate alongside professionals in some or all stages of the research process. The bidirectional benefits it generates, especially in the field of health, including empowerment, new hypotheses, and results, and addressing issues truly important to society, justify the necessity to establish a common framework and address barriers to ensure a fruitful evolution of this new approach within nursing research. The aim was to analyze nursing projects with a citizen science focus that have been conducted. METHODS: PRISMA guidelines were employed to conduct a systematic review. Searches were conducted on PubMed, CINHAL, LILACS, IBECS, and Cochrane. Following the identification and screening process, 13 studies were included. The quality of the articles was assessed using the Joanna Brigg Institute (JBI) critical appraisal checklist and the quality of citizen science research using the Citizen Science Appraisal Tool. RESULTS: Citizen science studies in nursing were notably recent (2017-2023). Five research areas were identified, with environmental health being the most predominant. Multiple tools, both technological and traditional, were utilized, with the "Photovoice" and "Our Voice" methodologies being prominent. Citizen participation was limited to data collection and analysis in 7 out of the 13 studies, with most studies working with small samples. Findings regarding the application of this practice were positive, but no study exceeded 26 points on the CSAT scale to be considered high quality in citizen science. CONCLUSIONS: Citizen science can be a promising approach within the field of nursing. There is a need to increase individual participation to fully realize the potential bidirectional benefits. It is imperative to establish a common theoretical framework and continue working on the development of this methodology within nursing.
