ABSTRACT
INTRODUCTION: The use of YouTube® has spread among patients with chronic diseases such as multiple sclerosis (MS). These patients consult the available videos to learn more about their disease in terms of diagnosis and making decisions about treatments, including rehabilitation. The aim of this study was to evaluate the content, educational value, and quality analysis of MS videos about neurorehabilitation on YouTube® using quantitative instruments. MATERIALS AND METHODS: A search was conducted on YouTube®. The first 30 videos that met the inclusion criteria were reviewed. The videos were classified according to the upload source and the content. All videos included in the review were assessed by the DISCERN questionnaire, the JAMA benchmark, the global quality scale (GQS) and the video information and quality index (VIQI). RESULTS: The mean scores were: 28.3 (±9.33) in DISCERN, 2 (±0.81) in JAMA, 2.57 (±1.22) in GQS, and 11.73 (±4.06) in VIQI. JAMA score statistically significantly differed according to upload source (p = 0.002), video content (p = 0.023) and the speaker (p = 0.002). The DISCERN, JAMA, GQS, and VIQI scores showed significant correlations with each other. CONCLUSIONS: The analyzed videos about neurorehabilitation in people with MS on YouTube® were quite old since the upload, with a moderate duration and number of views, but with a poor quality of the content, educational value, and quality analysis of the videos. Our research showed that there were statistically significant differences in terms of quality, transparency, and reliability of the information, depending on the upload source, video content and the speaker.
TITLE: Análisis de contenido, valor educativo y calidad de los vídeos sobre neurorrehabilitación de la esclerosis múltiple en YouTube®.Introducción.

AIM: Deficits in mentalization have been described in several mental disorders, but information is still scarce and ambiguous about the types of mentalization errors in each disorder and their specificity and severity in borderline personality disorder (BPD). Due to the high comorbidity between this disorder and axis I disorders, the aim of this work is to study differences in mentalization responses in BPD considering the different comorbidity profiles with other disorders. METHODS: A total of 141 BPD patients were evaluated using The Mini-International Neuropsychiatric Interview (MINI), to identify comorbid axis I disorders. Mentalizing ability was assessed by the Movie for the Assessment of Social Cognition (MASC). Statistical associations were analysed into the different variables. RESULTS: Patients with comorbid BPD and anorexia nervosa (AN), suicidal behaviour disorder or post-traumatic stress disorder (PTSD) respectively presented higher overmentalization, undermentalization and absence of mentalization errors, compared with patients with BPD without comorbidity. CONCLUSIONS: Results show that BPD comorbidity with AN, suicidal behaviour disorder and PTSD affect to the types and severity of mentalizing deficits observed in these patients. This study highlights the importance of the assessment and treatment of axis I comorbid disorders in borderline personality disorder, with the objective of shaping personalized treatment for every patient.
ABSTRACT
OBJECTIVES: While the association between pregestational obesity and perinatal complications has been established, it is necessary to update the current understanding of its impact on maternal and foetal health due to its growing prevalence. Thus, this study aimed to investigate the association between pregestational obesity with the leading perinatal complications during the last 6 years. STUDY DESIGN: A cross-sectional study was performed in San Felipe, Chile. Anonymised data of 11,197 deliveries that occurred between 2015 and 2021 were included. METHODS: Pregestational body mass index was defined according to the World Health Organisation during the first trimester of pregnancy. The association between pregestational obesity and perinatal complications was analysed by calculating the odds ratio (OR), which was adjusted for confounding variables. Statistical differences were considered with a P-value of <0.05. RESULTS: The prevalence of pregestational obesity was 30.1%. Pregestational obesity was related to a high incidence of perinatal complications (≥3 complications; P < 0.0001). The main perinatal complications were caesarean section, large for gestational age (LGA), gestational diabetes (GD), macrosomia, hypertensive disorders of pregnancy (HDP), premature rupture of membranes (PROM), intrauterine growth restriction, and failed induction. Pregestational obesity was shown to be a risk factor for macrosomia (OR: 2.3 [95% confidence interval {95% CI}: 2.0-2.8]), GD (OR: 1.9 [95% CI: 1.6-2.1]), HDP (OR: 1.8 [95% CI: 1.5-2.1]), LGA (OR: 1.6 [95% CI: 1.5-1.8]), failed induction (OR: 1.4 [95% CI: 1.0-1.8]), PROM (OR: 1.3 [95% CI: 1.1-1.6]), and caesarean section (OR: 1.3 [95% CI: 1.2-1.4]). CONCLUSIONS: Pregestational obesity has been shown to be a critical risk factor for the main perinatal complications in the study population. Pregestational advice is imperative not only in preventing pregestational obesity but also in the mitigation of critical perinatal complications once they arise.

Sitosterolemia is a rare autosomal recessive disease that lead to an increase in the intestinal absorption and decreased biliary excretion plant sterols. It is caused by mutations in ABCG5 and ABCG8 genes, encoring sterolin-1 and sterolin-2 protein. The main clinical manifestations are xanthomas, premature atherosclerosis, arthralgia and, of note, hematological alterations. As in many other systemic diseases, hematological manifestations may be the only notable finding, for this reason we want to highlight the importance of multidisciplinary work and raise awareness of this rare disease that can lead to serious consequences if not treated prematurely. Here we present a case of this disease as well as its entire diagnostic process developed from a simple analytical alteration.
ABSTRACT
Platinum group element levels have increased in natural aquatic environments in the last few decades, in particular as a consequence of the use of automobile catalytic converters on a global scale. Concentrations of Pt over tens of µg L-1 have been observed in rivers and effluents. This raises questions regarding its possible impacts on aquatic ecosystems, as Pt natural background concentrations are extremely low to undetectable. Primary producers, such as microalgae, are of great ecological importance, as they are at the base of the food web. The purpose of this work was to better understand the impact of Pt on a cellular level for freshwater unicellular algae. Two species with different characteristics, a green alga C. reinhardtii and a diatom N. palea, were studied. The bioaccumulation of Pt as well as its effect on growth were quantified. Moreover, the induction or repression factors of 16 specific genes were determined and allowed for the determination of possible intracellular effects and pathways of Pt. Both species seemed to be experiencing copper deficiency as suggested by inductions of genes linked to copper transporters. This is an indication that Pt might be internalized through the Cu(I) metabolic pathway. Moreover, Pt could possibly be excreted using an efflux pump. Other highlights include a concentration-dependent negative impact of Pt on mitochondrial metabolism for C. reinhardtii which is not observed for N. palea. These findings allowed for a better understanding of some of the possible impacts of Pt on freshwater primary producers, and also lay the foundations for the investigation of pathways for Pt entry at the base of the aquatic food web.

BACKGROUND: The prevalence of malnutrition is high among the elderly population. Hospital admission is a window of opportunity for its detection. OBJECTIVE: To assess the concordance of different nutritional scales in hospitalized patients. METHODS: Prospective study in non-institutionalized patients over 65 years of age admitted to an internal medicine department. Five malnutrition screening surveys (MNA, MST, MUST, NRS-2000 and CONUT) and three nutritional risk screening surveys (SCREEN 3, 8 and 14) were compared. As gold standard we use the Global Malnutrition Leadership Initiative for Malnutrition (GLIM) definition of malnutrition. RESULTS: Eighty-five patients (37% female, median age 83 years) were included. Forty-eight percent (95% CI 38-59%) of patients were classified as malnourished according to GLIM criteria. The SCREEN 3 scale was the most sensitive (93%; 95% CI 87-98) and MUST the most specific (91%; CI 85-99). The most effective scale for excluding suspected malnutrition was SCREEN 3 (LR- 0.17; 95% CI 0.05-0.53) and the best for confirming it was MST (LR+ 7.08; 95% CI 3.06-16.39). Concordance between the different scales was low or very low with kappa indices between 0.082 and 0.465. CONCLUSIONS: A comprehensive approach is needed to detect malnutrition in hospitalized patients. More sensitive scales are more useful in initial screening. Nutritional risk tools could be effective at this stage. In a second step, malnutrition should be confirmed according to established criteria such as GLIM.

BACKGROUND: HER2DX, a multianalyte genomic test, has been clinically validated to predict breast cancer recurrence risk (relapse risk score), the probability of achieving pathological complete response post-neoadjuvant therapy (pCR likelihood score), and individual ERBB2 messenger RNA (mRNA) expression levels in patients with early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer. This study delves into the comprehensive analysis of HER2DX's analytical performance. MATERIALS AND METHODS: Precision and reproducibility of HER2DX risk, pCR, and ERBB2 mRNA scores were assessed within and between laboratories using formalin-fixed paraffin-embedded (FFPE) tumor tissues and purified RNA. Robustness was appraised by analyzing the impact of tumor cell content and protocol variations including different instruments, reagent lots, and different RNA extraction kits. Variability was evaluated across intratumor biopsies and genomic platforms [RNA sequencing (RNAseq) versus nCounter], and according to protocol variations. RESULTS: Precision analysis of 10 FFPE tumor samples yielded a maximal standard error of 0.94 across HER2DX scores (1-99 scale). High reproducibility of HER2DX scores across 29 FFPE tumors and 20 RNAs between laboratories was evident (correlation coefficients >0.98). The probability of identifying score differences >5 units was ≤5.2%. No significant variability emerged based on platform instruments, reagent lots, RNA extraction kits, or TagSet thaw/freeze cycles. Moreover, HER2DX displayed robustness at low tumor cell content (10%). Intratumor variability across 212 biopsies (106 tumors) was <4.0%. Concordance between HER2DX scores from 30 RNAs on RNAseq and nCounter platforms exceeded 90.0% (Cohen's κ coefficients >0.80). CONCLUSIONS: The HER2DX assay is highly reproducible and robust for the quantification of recurrence risk, pCR likelihood, and ERBB2 mRNA expression in early-stage HER2-positive breast cancer.

BACKGROUND: Short-duration (3-5 days) antibiotic treatment of uncomplicated urinary tract infection (uUTI) in children >24 months of age is equivalent to longer-duration antibiotic treatment, with added benefits of antibiotic stewardship. At our pediatric emergency department (ED), 13% of 5- to 18-year-old patients discharged with uUTI received ≤5 days of antibiotics. We aimed to increase short-duration prescriptions in patients with uUTI from 13% to >50% over 12 months. METHODS: This quality improvement project was conducted from January 2021 to August 2022. Complicated UTI was excluded. Interventions included education, practice feedback, and electronic health record changes. The outcome measure, the proportion of children treated with a short antibiotic duration, was studied by using p-charts. Antibiotic days saved were calculated. Revisits with UTI within 14 days of confirmed uUTI treated with short-duration antibiotics (balancing measure) were analyzed by using Fisher's exact test. RESULTS: In 1292 (n = 363 baseline, 929 post-intervention) eligible patients treated for uUTI, shorter antibiotic duration increased from 13% to 91%. We met our 50% aim within 2 months, with continued improvement leading to an additional centerline shift. Consequently, 2619 antibiotic days were saved. Two of 334 (0.6%) patients returned (P = NS) within 14 days of the index visit with a culture-positive uUTI. CONCLUSIONS: By using education, feedback, and electronic health record changes, we decreased antibiotic duration in children discharged from the ED for uUTI without a significant increase in return visits with UTI. These interventions can be expanded to wider age groups and other outpatient settings.

The relationship between ethics and artificial intelligence in medicine is a crucial and complex topic that falls within its broader context. Ethics in medical artificial intelligence (AI) involves ensuring that technologies are safe, fair, and respect patient privacy. This includes concerns about the accuracy of diagnoses provided by artificial intelligence, fairness in patient treatment, and protection of personal health data. Advances in artificial intelligence can significantly improve healthcare, from more accurate diagnoses to personalized treatments. However, it is essential that developments in medical artificial intelligence are carried out with strong ethical consideration, involving healthcare professionals, artificial intelligence experts, patients, and ethics specialists to guide and oversee their implementation. Finally, transparency in artificial intelligence algorithms and ongoing training for medical professionals are fundamental.

MATERIAL AND METHOD: A systematic review was made following the PRISMA recommendations on the use of metaphyseal sleeves for revision total knee arthroplasty. We included prospective and retrospective studies published in the last 10 years looking at implant survivorship, clinical and functional outcome with a minimum follow-up of 2 years. RESULTS: The included studies showed good both functional and clinical outcomes. The overall reoperation rate was 16.2%, with an overall survival rate of 92.2% and aseptic survivorship of 98.2%. CONCLUSIONS: Metaphyseal sleeves are a good treatment option for this surgery, especially in AORI II or III type bone defects, achieving good intraoperative and primary stability of the implant, with good and rapid osseointegration.
ABSTRACT
Scabies is an ectoparasitic dermatosis caused by the Sarcoptes scabiei var. hominis mite, which lives and reproduces in humans. Its incidence in Spain has increased in recent years. The aim of this study was to complement existing evidence on the increasing number of scabies cases in our country by analyzing changes in ectoparasiticide prescriptions and Internet searches for scabies infestations measured by Google Trends. We also examined correlations between these two variables. Our results show that public interest in scabies has increased in recent years and is positively and significantly correlated with an increasing use of ectoparasiticides. We believe that Google Trends should be considered as a complementary tool for monitoring real-time trends in scabies infestations in Spain.

Abstract The present research was made to determine the micronuclei and cytotoxic capacity of the antidepressant venlafaxine in an in vivo acute and subchronic assays in mouse. In the first study, we administered once 5, 50, and 250 mg/kg of the drug, and included a negative and a daunorubicin treated group. Observations were daily made during four days. The subchronic assay lasted 5 weeks with daily administration of venlafaxine (1, 5, and 10 mg/kg) plus a negative and an imipramine administered groups. Observations were made each week. In the first assay results showed no micronucleated polychromatic erythrocytes (MNPE) increase, except with the high dose at 72 h. The strongest cytotoxic effect was found with 250 mg/kg at 72 h (a 51% cytotoxic effect in comparison with the mean control level). In the subchronic assay no MNPE increase was found; however, with the highest dose a significant increase of micronucleated normochromatic erythrocytes was observed in the last three weeks (a mean of 51% respect to the mean control value). A cytotoxic effect with the two high doses in the last two weeks was observed (a polychromatic erythrocyte mean decrease of 52% respect to the mean control value). Results suggest caution with venlafaxine.

No primeiro estudo, administramos uma vez 5, 50 e 250 mg/kg do medicamento e incluímos um grupo negativo e um grupo tratado com daunorubicina. As observações foram feitas diariamente durante quatro dias. O ensaio subcrônico durou cinco semanas com administração diária de venlafaxina (1, 5, e 10 mg/kg) mais um grupo negativo e um grupo administrado de imipramina. As observações foram feitas a cada semana. No primeiro ensaio, os resultados não mostraram aumento de eritrócitos policromáticos micronucleados (MNPE), exceto com a dose elevada a 72 h. O efeito citotóxico mais forte foi encontrado com 250 mg/kg a 72 h (um efeito citotóxico de 51% em comparação com o nível médio de controle). No ensaio subcrônico não foi encontrado aumento de MNPE; entretanto, com a dose mais alta, um aumento significativo de eritrócitos normocromáticos micronucleados foi observado nas últimas três semanas (média de 51% em relação ao valor médio de controle). Foi observado um efeito citotóxico com as duas altas doses nas últimas duas semanas (uma diminuição média de 52% em relação ao valor médio de controle dos eritrócitos policromáticos). Os resultados sugerem cautela com a venlafaxina.

ABSTRACT
In this work, we describe a simple wet chemical route for preparing silver sulfide nanoparticles (Ag2S) encapsulated with thioglycolic acid (TGA). By using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), energy dispersive X-ray (EDS) microanalysis, transmission electron microscopy (TEM), and dynamic light scattering (DLS), we have found that these nanoparticles were enrobed by TGA molecules and they have an Ag/S ratio nearly equal to 2.2 and a nearly spherical shape with two average size populations. Photoluminescence (PL) spectroscopy has shown that these nanoparticles are highly luminescent, photostable and photobleaching resistant and they emit in the first biologic window with a band peaking in the NIR region at 915 nm. We have demonstrated through a 3-(4,5-dimethyl-thiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) assay protocol and using U-87 MG human living cells that these nanoparticles are biocompatible with a viability ratio higher than 80% for a concentration equal to 100 µg mL-1. By investigating the effect of pH, ionic strength and thermal quenching on the PL emission, we have shown that these nanoparticles provide a convenient stable tool to measure temperature in the biological range with a relative thermal sensitivity higher than 5% per °C and they may be used as suitable fluorescent probes for living cell imaging and intracellular temperature mapping.
ABSTRACT
BACKGROUND: Adequate and effective emergency preparedness for hospital surge capacity is a prerequisite to ensuring standard healthcare services for disaster victims. This study aimed to identify, review, and synthesize the preparedness activities for and the barriers to hospital surge capacity in disasters and emergencies. METHODS: We systematically searched seven databases (PubMed, MEDLINE, CINAHL, Scopus, Embase, Ovid, and PsycINFO). We included all English peer-reviewed studies published in January 2016 and July 2022 on surge capacity preparedness in hospital settings. Two independent researchers screened titles and abstracts, reviewed the full texts, and conducted data extractions using CADIMA software. We assessed the rigor of the included studies using the NIH quality assessment tools for quantitative studies, the Noyes et al. guidelines for qualitative studies, and the MMAT tool for mixed methods studies and summarized findings using the narrative synthesis method. We also used PRISMA reporting guidelines. RESULTS: From the 2560 studies identified, we finally include 13 peer-reviewed studies: 10 quantitative, one qualitative, and two mixed methods. Five studies were done in the USA, three in Iran (n = 3), and the remaining in Australia, Pakistan, Sweden, Taiwan, and Tanzania. The study identified various ways to increase hospital surge capacity preparedness in all four domains (staff, stuff, space, and system); among them, the use of the Hospital Medical Surge Preparedness Index and the Surge Simulation Tool for surge planning was noteworthy. Moreover, nine studies (69%) recognized several barriers to hospital surge capacity preparedness. CONCLUSION: The review provides synthesized evidence of contemporary literature on strategies for and barriers to hospital surge capacity preparedness. Despite the risk of selection bias due to the omission of gray literature, the study findings could help hospital authorities, public health workers, and policymakers to develop effective plans and programs for improving hospital surge capacity preparedness with actions, such as enhancing coordination, new or adapted flows of patients, disaster planning implementation, or the development of specific tools for surge capacity.

The industrial adoption of low-carbon technologies and renewable electricity requires novel tools for electrifying unitary steps and efficient energy storage, such as the catalytic synthesis of valuable chemical carriers. The recently-discovered use of microwaves as an effective reducing agent of solid materials provides a novel framework to improve this chemical-conversion route, thanks to promoting oxygen-vacancy formation and O2-surface exchange at low temperatures. However, many efforts are still required to boost the redox properties and process efficiency. Here, we scrutinise the dynamics and the physicochemical dependencies governing microwave-induced redox transformations on solid-state ion-conducting materials. The reduction is triggered upon a material-dependent induction temperature, leading to a characteristically abrupt rise in electric conductivity. This work reveals that the released O2 yield strongly depends on the material's composition and can be tuned by controlling the gas-environment composition and the intensity of the microwave power. The reduction effect prevails at the grain surface level and, thus, amplifies for fine-grained materials, and this is ascribed to limitations in oxygen-vacancy diffusion across the grain compared to a microwave-enhanced surface evacuation. The precise cyclability and stability of the redox process will enable multiple applications like gas depuration, energy storage, or hydrogen generation in several industrial applications.
ABSTRACT
OBJECTIVE: To describe patients hospitalized in internal medicine in terms of malnutrition and sarcopenia, depending on the presence or absence of type 2 diabetes mellitus (DM2), as well as to evaluate short- and long-term mortality related to both. METHODS: Cross-sectional, single-center study, which included consecutive patients admitted to internal medicine in May and October 2021. Malnutrition was determined using the Mini Nutritional Assessment-Short Form (MNA-SF) and sarcopenia using SARC-F and handgrip strength. Patients hospitalized for more than 48â¯h are excluded. RESULTS: 511 patients were analyzed, 49.1% male, mean age 75.2 +/- 15 years, 210 (41.1%) DM2. 6 groups (2â¯×â¯3 design) are generated based on the presence of DM2 and the nutritional status according to the result of the MNA-SF: 12-14 points, without risk; MNA-SF 8-12 points, high risk; MNA-SF 0-7 points, malnourished. Malnourished patients with DM2 had significantly higher sarcopenia, comorbidity, inflammation, and pressure ulcers. The main determinants of in-hospital mortality were sarcopenia (OR 1.27, 95%CI 1.06-1.54, pâ¯=â¯0.01), comorbidity (OR 1.27, 95%CI 1,08-1,49, pâ¯=â¯0.003) and inflammation (OR 1.01, 95%CI 1.00-1.02, pâ¯=â¯0.02). The 120-day prognosis was worse among malnourished patients (pâ¯=â¯0.042). CONCLUSION: Patients admitted with DM2 have a similar degree of malnutrition than the rest, but with greater sarcopenia. This sarcopenia, together with inflammation and comorbidity determine a worse prognosis. The active and early identification of malnutrition and sarcopenia and their subsequent approach could improve the prognosis of patients.
