Lightweight Mortar Incorporating Expanded Perlite, Vermiculite, and Aerogel: A Study on the Thermal Behavior.

Climate change is compelling countries to alter their construction and urbanization policies to minimize their impact on the environment. The European Union has set a goal to reduce greenhouse gas emissions by 55%, recognizing that 50% of its emissions originate from maintaining thermal comfort within buildings. As a response, the EU has developed comprehensive legislation on energy efficiency. In this article, special mortars using aerogel, perlite, and vermiculite as lightweight aggregates were prepared and studied to enhance the thermal properties of the mortar. Their thermal properties were examined and, using a solar simulator for both hot and cold conditions, it was found that varying proportions of these lightweight aggregates resulted in a mortar that provided insulation from the exterior up to 7 °C more than the reference mortar in warm conditions and up to 4.5 °C in cold conditions.

Current characteristics of patients with hepatitis C virus: results from an automated alert system.

Alert systems are proving to be useful to increase hepatitis C virus (HCV) diagnoses and facilitating access to antiviral treatment. Since 2020, our health department has had a fully automated alert system set up at the Microbiology Department. In this study, we present the results of the 2022-2023 period to assess the current characteristics of HCV diagnosed patients. In addition, we analyzed, through a comparison, whether a limitation that we noticed during the 2020-2021 period (whose results were published) is still present. This limitation consists of that 24.2% (34/134) of those candidates for antiviral treatment were not treated because they could not be located or refused treatment. During the 2022-2023 period, 188 new cases were diagnosed, and 75% (141/188) were treated. The comparison of both periods showed that in 2022-2023, the rate of treatment rejection by the patient was significantly lower (1.4% vs 14.5%, p < 0.05) and, therefore, the rate of antiviral treatment increased (75% vs 58.9%, p < 0.05). These results suggest that our alert system is useful and efficient for the diagnosis and treatment of HCV.

Hepatitis B virus reactivation after ibrutinib treatment.

New immunosuppressive and antineoplastic drugs are becoming both more numerous and more widely used, even during several years. Most of them present a low-moderate risk of hepatitis B virus (HBV) reactivation in HBsAg-negative and anti-HBc-positive patients. However, their reactivation capacity has not been clearly studied. We present the clinical case of a patient with these serological characteristics who, after 5 years of treatment with ibrutinib for chronic lymphocytic leukaemia, developed VHB reactivation, which was controlled with tenofovir. The occurrence of this event with drugs such as ibrutinib may lead to changes in HBV reactivation prophylaxis.

Impact of antiseizure medication with a very long half-life on long term video-EEG monitoring in focal epilepsy.

PURPOSE: To assess the impact of antiseizure medications (ASMs) with a very long half-life on long term video-EEG monitoring (LTM) in people with focal epilepsy (FE). METHODS: In this retrospective cohort study, we searched our local database for people with FE who underwent ASM reduction during LTM at the University Hospital of 'La Fe', Valencia, from January 2013 to December 2019. Taking into account the half-life of the ASM, people with FE were divided into two groups: Group A contained individuals who were taking at least one ASM with a very long half-life at admission, and Group B consisted of those not taking very long half-life ASMs. Using multivariable analysis to control for important confounders, we compared the following outcomes between both groups: seizure rates per day, time to first seizure, and LTM duration. RESULTS: Three hundred seventy individuals were included in the study (154 in Group A and 216 in Group B). The median recorded seizure rates (1.3 seizures/day, range 0-15.3 vs.1.3 seizures/day, range 0-9.3, p-value=0.68), median time to the first seizure (24 h, range 2-119 vs. 24 h, range 2-100, p-value=0.92), and median LTM duration (4 days, range 2-5 vs. 4 days, range 2-5, p-value=0.94) were similar in both groups. Multivariable analysis did not reveal any significant differences in the three outcomes between the two groups (all p-values>0.05). CONCLUSION: ASMs with a very long half-life taken as co-medication do not significantly affect important LTM outcomes, including recorded seizure rates, time to the first seizure, or LTM duration. Therefore, in general, there is no need to discontinue ASMs with a very long half-life prior to LTM.

Raising the quality of life of students in all university careers is one of the most important challenges for Physical Education specialists, and therapy in particular; however, when beneficiaries have spinal cord injuries, they need adequate physical and mental rehabilitation. The objective was to develop physical exercises as a treatment to compensate for the recovery time of students with spinal cord injuries who attend the therapeutic area of the Universidad de Oriente, through Physical Education classes. In the research, theoretical and empirical methods were used to know the real state of the problem, in addition to the techniques to collect and process information. The physical exercises proposed are fundamentally aimed at students who have scoliosis, and in a prophylactic-therapeutic way, treatment is offered to compensate and/or prevent the time of onset of pain that allows immediate recovery and incorporation into the teaching-learning process within the physical education classes. A structure and methodological ordering of the contents was taken into account in four staggered stages during the application of the treatment, in correspondence with the individual characteristics of the sample. The specialists who evaluated the proposal considered it feasible for its application and useful.

Stabilization of Enzymes by Using Thermophiles.

Manufactured steroid compounds have many applications in the pharmaceutical industry. Due to the chemical complexity and chirality of steroids, there is an increasing demand for enzyme-based bioconversion processes to replace those based on chemical synthesis. In this context, thermostability of the involved enzymes is a highly desirable property as both the increased half-life of the enzyme and the enhanced solubility of substrates and products will improve the yield of the reactions. Metagenomic libraries from thermal environments are potential sources of thermostable enzymes of prokaryotic origin, but the number of expected hits could be quite low for enzymes handling substrates such as steroids, rarely found in prokaryotes. An alternative to metagenome screening is the selection of thermostable variants of well-known steroid-processing enzymes. Here we review and detail a protocol for such selection, where error-prone PCR (epPCR) is used to introduce random mutations into a gene to create a variants library for further selection of thermostable variants in the thermophile Thermus thermophilus. The method involves the use of folding interference vectors where the proper folding of the enzyme of interest at high temperature is linked to the folding of a reporter encoding a selectable property such as thermostable resistance to kanamycin, leading to a life-or-death selection of variants of reinforced folding independently of the activity of the enzyme.

In general, there was a better coordination and development of skills to perform the different exercises and motor games in Physical Education classes.

Educational intervention for the main caregiver of primiparous women to promote breastfeeding and the association between prolactin and nutritional parameters.

Background: In the last two years, breastfeeding rates have experienced a notable decline worldwide. Only 46% of women breastfeed their children, the figure being much lower in primiparous women. Breastfed milk is the ideal food for babies; its benefits for the health of mothers and babies are scientifically proven. Several studies show that babies who are not breastfed have a higher risk of getting sick. This fact gives rise to an important public health problem. The aim of this paper is to describe the association between presence of the caregiver in health education and increasing rates of breastfeeding. Methods: We conducted an observational study (cohort) in a population of primiparous pregnant women (n = 88), and their main caregivers belonging to a region of central Spain. The development, content and implementation of the intervention consisted of: 1) obtaining the blood levels of pregnant women (prolactin, folic acid, vitamin B12 and transferrin) before health education (13-26 weeks of pregnancy), 2) carry out health education with two groups: A (44 pregnant women with caregivers) and B (44 without caregivers), 3) obtain the same blood levels as in the first intervention, 15 days after delivery, and finally the evaluation of the intervention with breastfeeding rates. Results: The levels of prolactin (288.57 ± 107.46 nanogrammes per millilitre (ng / ml)), folic acid (16.93 ± 4.09 ng / ml), vitamin B12 (505.05 ± 213.97 picogrammes (pg) / ml) and transferrin (296.82 ± 67.61 milligrammmes per decilitre (mg / dl)) were higher in pregnant women who attended the health education program with a caregiver than in pregnant women who attended alone: prolcoactin (103.61 ± 45.48 ng / ml), folic acid (7.16 ± 5.88 ng / ml), vitamin B12 (160.59 ± 36.92 pg / ml) and transferrin (223.86 ± 44.14 mg / dl). Of the sample size of 44 primiparous people who attended the talks with caregivers, 35 (79.54%) breastfed their babies, while the other 44 primiparous women who attended alone, only seven (15.91%) established breastfeeding successfully. Conclusions: The implications for public health research are that the presence of a caregiver in health education programs modifies levels of prolactin, folic acid, vitamin B12, and transferrin, as well as increasing breastfeeding rates.

Improved rock phosphate dissolution from organic acids is driven by nitrate assimilation of bacteria isolated from nitrate and CaCO3-rich soil.

Until now, the solubilization capacities of insoluble mineral P by soil microorganisms have been screened in vitro with media containing NH4+ as a nitrogen source. This presence of NH4+ will lead to an acidification of the medium responsible for the solubilization of the insoluble P. However, besides proton release, the production of organic acids can play a very important role in the release of free P. This physiological mechanism can largely depend on the source of nitrogen (NH4+vs NO3-) assimilated by the bacteria but the influence of the N source on the production of organic acids has yet to be studied. Our aim was to investigate if the N source assimilated by bacteria and the soil characteristics such as the dominant N source (NH4+vs NO3-) and CaCO3 contents might influence the bacterial capacities to solubilize rock phosphate. To fill this objective, we screened the capacity of bacteria isolated from 3 soils to solubilize rock phosphate in vitro in presence of NH4+or NO3-. Then, we selected the most efficient bacterial strains to identify and quantify the release of organic anions into the medium. Among the two hundred and forty-three bacterial strains isolated from the 3 soils, nine and seven isolates were identified with the highest % rock phosphate-solubilization values with NH4+ or NO3- as the sole N-source. Only one strain was able to release free Pi with NH4+ or NO3- as the sole N-source. The most predominant organic acids released by almost all isolates were gluconic acid, lactic acid, glycolic acid, acetic acid, formic acid and pyruvic acid regardless the N-source. However, with NO3- as source of N, the highest concentrations on those acids were found together with the highest release of free Pi into the medium. Molecular analysis of 16S rRNA indicated that almost all strains belonged to Bacillus and Paenibacillus genera. The PCA analysis between soil properties and bacterial capacities to release organic acids and free Pi also revealed that soil factors such as CaCO3 and soil NO3- content positively influenced the release of organic acids by bacteria grown in vitro. Our results concluded that the bacterial rock phosphate-solubilization was intimately related to organic acids production which in turn seemed to be driven by the assimilation of NO3- by bacteria. Therefore, the N-source might be considered a key factor to take into consideration during the screening and selection of suitable strains involved in the P-solubilization.

Consumers' willingness to pay for health claims during the COVID-19 pandemic: A moderated mediation analysis.

The COVID-19 pandemic has posed a substantial threat to people's lives and raised health concerns. This research explores the mediating role of consumers' attitudes towards health claims in the relationship between consumers' interest in health claims and their willingness to pay (WTP) for health claims in extra virgin olive oil (EVOO). Additionally, we examine the moderation effect of COVID-19 risk perception in the relationship between consumers' interest in and attitudes towards health claims. Data were collected through an online survey in three countries: Spain, the UK and Chile. Findings confirm the mediating role of consumers' attitudes towards health claims. Furthermore, the relationship between consumers' interest and their attitudes towards health claims was stronger when COVID-19 risk perception was higher.

Epidemiology of Fabry disease in patients in hemodialysis in the Madrid community.

This study screened for Fabry disease (FD) in patients in hemodialysis (HD) in the region of Madrid (CAM) with a cross-sectional design to evaluate HD-prevalent patients, followed by a three-year period prospective design to analyze HD-incident patients. INCLUSION CRITERIA: patients older than 18 years on HD in the CAM, excluding patients diagnosed with any other hereditary disease with renal involvement different from FD, that sign the Informed Consent (IC). EXCLUSION CRITERIA: underaged patients or not agreeing or not being capable of signing the IC. RESULTS: 3470 patients were included, 63% males and with an average age of 67.9±9.7 years. 2357 were HD-prevalent patients and 1113 HD-incident patients. For HD-prevalent patients, average time in HD was 45.2 months (SD 51.3), in HD-incident patients proteinuria was present in 28.4%. There were no statistical differences in plasmatic alpha-galactosidase A (α-GAL-A) activity or Lyso-GL-3 values when comparing HD-prevalent and HD-incident populations and neither between males and females. A genetic study was performed in 87 patients (2.5% of patients): 60 male patients with decreased enzymatic activity and 27 female patients either with a decreased GLA activity, increased Lyso-Gl3 levels or both. The genetic variants identified were: p.Asp313Tyr (4 patients), p.Arg220Gln (3 patients) and M290I (1 patient). None of the identified variants is pathogenic. CONCLUSIONS: 76% of HD Centers of the CAM participated in the study. This is the first publication to describe the prevalence of FD in the HD-population of a region of Spain as well as its average α-GAL-A-activity and plasmatic Lyso-Gl3 levels. It is also the first study that combines a cross-sectional design with a prospective follow-up design. This study has not identified any FD patient.

Best methods for urine sample collection for diagnostic accuracy in women with urinary tract infection symptoms: a systematic review.

BACKGROUND: Most guidelines recommend a midstream urine (MSU) or a midstream clean-catch (MSCC) sample for urinalysis. However, whether this sample is better than others is still controversial. OBJECTIVES: To assess the most adequate non-invasive method to collect a urine specimen for diagnosing urinary tract infections (UTI) in symptomatic non-pregnant women. METHODS: This review was conducted according to the Systematic Reviews of Diagnostic Test Accuracy guidelines (PROSPERO CRD42021241758). PubMed was searched paired sample studies and controlled trials. Studies comparing MSCC, MSU without cleaning, first-void urine, and random voiding samples were considered. Studies evaluating invasive methods were excluded. The main outcome was diagnostic accuracy of urine cultures. Contamination rates were evaluated. The risk of bias tool for systematic reviews on diagnostic accuracy (QUADAS-2) was assessed. RESULTS: Six studies including 1,010 patients were evaluated. Only two studies used paired samples. No study was considered as having low risk of bias. There was no difference in contamination for MSU specimens collected with or without cleansing and between random void urine collection and MSCC. In one study comparing first-void urine with MSU samples, the contamination rate was lower in the latter, but the gold standard of urine culture was only used for one sampling collection. CONCLUSIONS: To the best of our knowledge, this systematic review is the first to assess the evidence available from different exclusively non-invasive urine sampling. Despite being widely recommended, our review did not find consistent evidence that asking women to provide midstream samples with or without cleansing is better.

Urine is one type of specimen that can be easily collected from a patient. Urinalysis testing can give the doctor valuable information about the presence of an infection in the urine and the type of microorganism causing this infection. The physician can also use the information from urine testing to diagnose and treat other diseases. The collection of the mid-stream of the urination has always been advocated. However, this recommendation has never been proven with good quality studies, and the results of the studies carried out so far have been controversial. In a systematic review, we recently determined that the use of any specimen during urination is as good as midstream collection when patients are requested to provide a urine sample and in terms of quality even specimens collected without proper cleansing are also comparable to mid-stream collection with cleansing. In the present systematic review, we evaluated the most adequate non-invasive method to collect a urine specimen for diagnosing urinary tract infections in symptomatic non-pregnant women. We identified only six studies comparing different urine sampling techniques and we did not observe any difference regarding the quality of the urine between them.

Outcomes of an automated alert system from Microbiology to link diagnosis to treatment in patients with hepatitis C virus.

INTRODUCTION: simplification strategies for the care circuit of patients with hepatitis C virus (HCV) are key to achieve eradication. An electronic identification system was set up for HCV serology to link diagnosis to specialist management, aimed to reduce patient loss. MATERIAL AND METHODS: a retrospective, single-center study was performed in patients with HCV identified from 15/3/2020 to 15/12/2021, using an alert system from Microbiology that notified specialists of positive cases. The patient was contacted and appointed a Fibroscan® and viral load measurement, with antiviral therapy prescribed on the same day. Origin, public health data, patient location rate and antiviral therapy prescription were recorded. RESULTS: of 174 patients identified, 171 had positive viremia, with a mean age of 59.6 ± 15.9 years, 61.5 % were males and 81.2 % were Spanish nationals. Origin in the outpatient setting predominated (57.9 %, 99/171), particularly Primary Care (51/171), penitentiaries (21/171) and addiction units (14/171). Overall, 43.3 % (74/171) were aware of their diagnosis; 19.4 % (20/103) of patients had F3 fibrosis and 25.2 % (26/103) had F4 fibrosis. Also, 78.4 % (134/171) were deemed candidates for treatment. Of these, 74.6 % (100/134) were located and treatment was initiated, and all those who completed their treatment achieved a sustained viral response (96/96). This system managed 58.5 % (100/171) of the patients identified. The only association found between antiviral therapy and patient variables was comorbidities with being untreated (OR, 7.14; p ˂ 0.001). CONCLUSIONS: this alert system allows to minimize patient loss in the care circuit and provides high rates of treated patients.

Hepatocellular carcinoma risk-stratification based on ASGR1 in circulating epithelial cells for cancer interception.

Purpose: Lack of diagnostic and prognostic biomarkers in hepatocellular carcinoma impedes stratifying patients based on their risk of developing cancer. The aim of this study was to evaluate phenotypic and genetic heterogeneity of circulating epithelial cells (CECs) based on asialoglycoprotein receptor 1 (ASGR1) and miR-122-5p expression as potential diagnostic and prognostic tools in patients with hepatocellular carcinoma (HCC) and liver cirrhosis (LC). Methods: Peripheral blood samples were extracted from LC and HCC patients at different disease stages. CECs were isolated using positive immunomagnetic selection. Genetic and phenotypic characterization was validated by double immunocytochemistry for cytokeratin (CK) and ASGR1 or by in situ hybridization with miR-122-5p and CECs were visualized by confocal microscopy. Results: The presence of CECs increased HCC risk by 2.58-fold, however, this was only significant for patients with previous LC (p = 0.028) and not for those without prior LC (p = 0.23). Furthermore, the number of CECs lacking ASGR1 expression correlated significantly with HCC incidence and absence of miR-122-5p expression (p = 0.014; r = 0.23). Finally, overall survival was significantly greater for patients at earlier cancer stages (p = 0.018), but this difference was only maintained in the group with the presence of CECs (p = 0.021) whereas progression-free survival was influenced by the absence of ASGR1 expression. Conclusion: Identification and characterization of CECs by ASGR1 and/or miR-122-5p expression may be used as a risk-stratification tool in LC patients, as it was shown to be an independent prognostic and risk-stratification marker in LC and early disease stage HCC patients.

Exploring Next Generation Probiotics for Metabolic and Microbiota Dysbiosis Linked to Xenobiotic Exposure: Holistic Approach.

Variation of gut microbiota in metabolic diseases seems to be related to dysbiosis induced by exposure to multiple substances called Microbiota Disrupting Chemicals (MDCs), which are present as environmental and dietary contaminants. Some recent studies have focused on elucidating the alterations of gut microbiota taxa and their metabolites as a consequence of xenobiotic exposures to find possible key targets involved in the severity of the host disease triggered. Compilation of data supporting the triad of xenobiotic-microbiota-metabolic diseases would subsequently allow such health misbalances to be prevented or treated by identifying beneficial microbe taxa that could be Next Generation Probiotics (NGPs) with metabolic enzymes for MDC neutralisation and mitigation strategies. In this review, we aim to compile the available information and reports focused on variations of the main gut microbiota taxa in metabolic diseases associated with xenobiotic exposure and related microbial metabolite profiles impacting the host health status. We performed an extensive literature search using SCOPUS, Web of Science, and PubMed databases. The data retrieval and thorough analyses highlight the need for more combined metagenomic and metabolomic studies revealing signatures for xenobiotics and triggered metabolic diseases. Moreover, metabolome and microbiome compositional taxa analyses allow further exploration of how to target beneficial NGP candidates according to their alleged variability abundance and potential therapeutic significance. Furthermore, this holistic approach has identified limitations and the need of future directions to expand and integrate key knowledge to design appropriate clinical and interventional studies with NGPs. Apart from human health, the beneficial microbes and metabolites identified could also be proposed for various applications under One Health, such as probiotics for animals, plants and environmental bioremediation.

Intra-cavitary brachytherapy in endometrial carcinoma: experience with cobalt-60 source.

Purpose: To report vaginal cuff brachytherapy (VCB) dosimetry parameters and clinical outcomes of patients with localized endometrial cancer treated with adjuvant high-dose-rate (HDR) brachytherapy using a cobalt-60 (60Co) source. Material and methods: Between 2011 and 2017, we identified patients with endometrial cancer treated with surgery and adjuvant VCB. Dosimetry variables analyzed included D2cc, D1cc, and D0.1cc for organs at risk (OARs) and distance from cylinder surface to 150% and 200% isodose line in vaginal mucosa. Local relapse (LR), regional relapse (RR), distant metastasis (DM), progression-free survival (PFS), and overall survival (OS) were analyzed using Kaplan-Meier, and log-rank test was applied to assess differences between groups. Toxicity evaluation was tested for possible cross-correlation within dosimetric parameters using Pearson r test and stepwise multivariate linear regression. Results: We identified 93 suitable patients. Mean age at diagnosis was 66 years (range, 45-85 years). Most patients had endometrioid adenocarcinoma (61.3%), followed by papillary-serous carcinoma (11.8%). 71% of patients presented with FIGO stage I (35.5% IA and 35.5% IB), 11.8% were stage II, and 17.2% were stage III. Adjuvant external beam radiotherapy (EBRT) (range, 46-50.4 Gy) was used in 53.8% of patients, and adjuvant chemotherapy in 38.7%. Median follow-up was 39 months (range, 5-84 months). Three-year OS and PFS were 87.5% and 85.5%, respectively. LR was seen in 2.2% of cases, RR in 7.5%, and DM in 12.9%. Mean rectum D2cc/D0.1cc were 88.1% and 116%, and mean bladder D2cc/D0.1cc were 79.2% and 103.2%, respectively. The most common acute toxicity was vaginal mucositis (8.9% ≥ G2), and the most frequent chronic toxicity was vaginal stenosis (25.3% ≥ G1). Conclusions: Adjuvant high-dose-rate VCB with 60Co source for patients with endometrial cancer is well tolerated, with clinical and toxicity outcomes comparable to those reported with iridium-192 (192Ir) source.
