Detection of circulating vaccine-derived poliovirus type 2 (cVDPV2) in wastewater samples: a wake-up call, Finland, Germany, Poland, Spain, the United Kingdom, 2024.

In 2024, circulating vaccine-derived poliovirus type 2 (cVDPV2) was detected in wastewater samples in Finland, Germany, Poland, Spain and the United Kingdom (UK). All strains were genetically linked, but sequence analysis showed high genetic diversity among the strains identified within individual wastewater sites and countries and an unexpected high genetic proximity among isolates from different countries. Taken together these results, with sequential samples having tested positive in various sites, a broader geographic distribution beyond positive sampling sites must be considered.

Effect of urban structure, population density and proximity to contagion on COVID-19 infections during the SARS-CoV-2 Alpha and Omicron waves in Málaga, Spain, March 2020 to December 2021.

BackgroundThe potential impact of urban structure, as population density and proximity to essential facilities, on spatial variability of infectious disease cases remains underexplored.AimTo analyse the spatial variation of COVID-19 case intensity in relation to population density and distance from urban facilities (as potential contagion hubs), by comparing Alpha and Omicron wave data representing periods of both enacted and lifted non-pharmaceutical interventions (NPIs) in Málaga.MethodsUsing spatial point pattern analysis, we examined COVID-19 cases in relation to population density, distance from hospitals, health centres, schools, markets, shopping malls, sports centres and nursing homes by non-parametric estimation of relative intensity dependence on these covariates.

Adult vaccinations against respiratory infections.

Introduction: Lower respiratory infections have a huge impact on global health, especially in older individuals, immunocompromised people, and those with chronic comorbidities. The COVID-19 pandemic highlights the importance of vaccination. However, there are lower rates of vaccination in the adult population that are commonly due to a missed opportunity to vaccinate.

Impact of structure and composition on the digestibility and nutritional quality of alternative protein-rich extracts from the green seaweed Ulva lacinulata.

This study reports on the nutritional quality of protein-polysaccharide extracts obtained from the green seaweed Ulva lacinulata, through a previously optimized method, evaluating the impact of their distinct composition and structure. Protein solubility was strongly influenced by protein-polysaccharide interactions, being higher in extracts with lower polysaccharide content. This, in turn, had a significant impact on the in vitro protein digestibility.

Integrated biotechnological process based on submerged fermentation and sonotrode extraction as a valuable strategy to obtain phenolic enriched extracts from moringa leaves.

The present study explored the influence of submerged fermentation with different lactic acid bacteria (LAB) as a pre-treatment of moringa leaves before the extraction of phenolic compounds via sonotrode. The sonotrode extraction was optimized using a Box-Behnken design and the optimal conditions found were: 25 % ethanol, 5 min and 100 % amplitude. Folin-reacting substances and antioxidant activity were measured on hydroalcoholic extracts obtained from fermented moringa leaves and, individual phenolic compounds were determined by HPLC-ESI-TOF-MS for the first time.

High pressure processing at different hydration levels as a tool to enhance rice bran stability and techno-functionality.

High-pressure processing (HPP) enhances food safety and shelf life by inactivating microorganisms and preserving food quality, yet its effectiveness in low-humidity environments has not been evaluated. This study investigated the effects of HPP at 500 MPa for 15 min across varying hydration levels (15, 30, 60, 77 %) on rice bran (RB), aiming to identify microbial effectiveness, besides techno-functional and physicochemical properties. HPP effectively reduced mesophilic bacteria, molds and yeast of RB at > 15 % hydration level, achieving reductions of up to 4 logarithmic cycles in the latter, nearing the detection limit of the method.

Modulation of microbiota composition and markers of gut health after in vitro dynamic colonic fermentation of plant sterol-enriched wholemeal rye bread.

A human oral phase followed by a dynamic gastrointestinal digestion and colonic fermentation (simgi®) has been applied to wholemeal rye bread (WRB) and PS-enriched WRB (PS-WRB). The aim of this study was to evaluate the impact of these solid and high-fiber food matrices on the metabolism of PS, modulation of the microbiota and production of short-chain fatty acids (SCFA) and ammonium ion after a simulated chronic intake (5 days). In both breads, campesterol, campestanol, stigmasterol, β-sitosterol, sitostanol, Δ5-avenasterol, Δ5,24-stigmastadienol, Δ7-stigmastenol, and Δ7-avenasterol were identified, of which only β-sitosterol was metabolized to sitostenone after PS-WRB treatment.

Self-Enhancement in Latin America: Is It Linked to Interdependence?

Although individuals of Latin American heritage ( in short) are considered interdependent, they also value traits like uniqueness and positivity, like individuals of European American cultural heritage, who are considered independent. It remains unclear whether this inclination toward positivity extends to a bias in self-perception known as self-enhancement. Moreover, if Latin Americans are indeed self-enhancing, it is uncertain how these tendencies align with their interdependent cultural orientation.

Neutrophil-to-lymphocyte ratio as a predictor of short- and long-term complications in pediatric burns.

Background: Neutrophil-to-Lymphocyte Ratio (NLR) has been postulated as a useful inflammatory biomarker in the prediction of complications in different pediatric diseases. Our aim is to analyze the predictive value of NLR in the development of complications in burned children, both in the short-term (need for grafting) and in the long-term (need for surgery of the sequelae).

Methods: A retrospective study was performed on burned patients under 18-years admitted to our Burn Unit between 2015 and 2021.

Functional differentiation of human dental pulp stem cells into neuron-like cells exhibiting electrophysiological activity.

Background And Aim: Human dental pulp stem cells (hDPSCs) constitute a promising alternative for central nervous system (CNS) cell therapy. Unlike other human stem cells, hDPSCs can be differentiated, without genetic modification, to neural cells that secrete neuroprotective factors. However, a better understanding of their real capacity to give rise to functional neurons and integrate into synaptic networks is still needed.

Outcomes in stage IIA versus stage IIB/III in the PALLAS trial [ABCSG-42/AFT-05/PrE0109/BIG-14-13]).

Background: The PALLAS trial investigated the addition of palbociclib to standard adjuvant endocrine therapy to reduce breast cancer recurrence. This pre-specified analysis was conducted to determine whether adjuvant palbociclib benefited patients diagnosed with lower risk stage IIA disease compared to those with higher stage disease.

Methods: PALLAS was an international, multicenter, randomized, open-label, phase III trial, representing a public-private partnership between Pfizer, the Austrian Breast Cancer Study Group, and the U.

Mesenchymal stromal cells-derived extracellular vesicles in cartilage regeneration: potential and limitations.

Background: Articular cartilage injuries can lead to pain, stiffness, and reduced mobility, and may eventually progress to osteoarthritis (OA). Despite substantial research efforts, effective therapies capable of regenerating cartilage are still lacking. Mesenchymal stromal cells (MSCs) are known for their differentiation and immunomodulatory capabilities, yet challenges such as limited survival post-injection and inconsistent therapeutic outcomes hinder their clinical application.

Colorectal carcinogenesis in the Lynch syndromes and familial adenomatous polyposis: trigger events and downstream consequences.

Carcinogenesis encompasses processes that lead to increased mutation rates, enhanced cellular division (tumour growth), and invasive growth. Colorectal cancer (CRC) carcinogenesis in carriers of pathogenic APC (path_APC) and pathogenic mismatch repair gene (path_MMR) variants is initiated by a second hit affecting the corresponding wild-type allele. In path_APC carriers, second hits result in the development of multiple adenomas, with CRC typically emerging after an additional 20 years.

Frequency of remission achievement in the pre-treat-to-target decade in juvenile idiopathic arthritis.

Background: Over the past two decades there has been a remarkable advance in the management of juvenile idiopathic arthritis (JIA), which has led to considerable improvement in prognosis. In 2018, the introduction of the treat-to-target (T2T) strategy in JIA has been advocated to further ameliorate disease outcome. To provide a benchmark for comparing future outcomes in the "T2T era", this study investigates the percentage of JIA patients who achieved clinical inactive disease (CID) in the decade that preceded the publication of the T2T recommendations in JIA.

Single-cell RNA sequencing highlights the role of distinct natural killer subsets in sporadic amyotrophic lateral sclerosis.

Background: Neuroinflammation plays a major role in amyotrophic lateral sclerosis (ALS), and cumulative evidence suggests that systemic inflammation and the infiltration of immune cells into the brain contribute to this process. However, no study has investigated the role of peripheral blood immune cells in ALS pathophysiology using single-cell RNA sequencing (scRNAseq).

Methods: We aimed to characterize immune cells from blood and identify ALS-related immune alterations at single-cell resolution.

Replacing Theories with Evidence Around the Axes of the Eye in Intraocular Lens Selection: A Review for the Clinician.

The prevailing narrative in scientific literature has long overemphasized the role of ocular axes in intraocular lens (IOL) implantation, perpetuating misconceptions that have led to unnecessary exclusions of patients. Historical assumptions, coupled with inconsistent terminology and statistical inaccuracies, have muddled clinical decision-making. This review delves into these misconceptions, offering a critical reassessment of their relevance.

Accuracy and clinical applicability of plasma tau 181 and 217 for Alzheimer's disease diagnosis in a memory clinic cohort.

Plasma tau phosphorylated at threonine 181 (p-tau181) and 217 (p-tau217) have demonstrated high accuracy for Alzheimer's disease (AD) diagnosis, defined by CSF/PET amyloid beta (Aβ) positivity, but most studies have been performed in research cohorts, limiting their generalizability. We studied plasma p-tau217 and p-tau181 for CSF Aβ status discrimination in a cohort of consecutive patients attending an academic memory clinic in Spain (July 2019-June 2024). All patients had CSF AD biomarkers performed as part of their routine clinical assessment.

Depression, anxiety and stress in taxi drivers: a systematic review of the literature.

Purpose: Mental health is a global public health challenge, with mental disorders being a major cause of morbidity. Particularly, taxi drivers face unique challenges related to long working hours, economic instability, and hazardous working conditions. To summarise the existing scientific literature on mental disorders in taxi drivers and identify associated variables.

KorB switching from DNA-sliding clamp to repressor mediates long-range gene silencing in a multi-drug resistance plasmid.

Examples of long-range gene regulation in bacteria are rare and generally thought to involve DNA looping. Here, using a combination of biophysical approaches including X-ray crystallography and single-molecule analysis for the KorB-KorA system in Escherichia coli, we show that long-range gene silencing on the plasmid RK2, a source of multi-drug resistance across diverse Gram-negative bacteria, is achieved cooperatively by a DNA-sliding clamp, KorB, and a clamp-locking protein, KorA. We show that KorB is a CTPase clamp that can entrap and slide along DNA to reach distal target promoters up to 1.

Ionized calcium and PTH as predictors of hypoparathyroidism following total thyroidectomy.

Purpose: Post-surgical hypoparathyroidism (POSH) is a common complication after total thyroidectomy. This study aims to assess the accuracy of serum and ionized calcium and PTH levels on the first postoperative day (POD-1) to predict postoperative hypocalcemia (PoHC), transient hypoparathyroidism (THPT), and permanent hypoparathyroidism (PtHPT).

Methods: Biochemical parameters and clinical variables were retrospectively analyzed in 200 patients.

The first insight into Acanthocephalus (Palaeacanthocephala) satellitome: species-specific satellites as potential cytogenetic markers.

Acanthocephalan parasites are often overlooked in many areas of research, and satellitome and cytogenetic analyzes are no exception. The species of the genus Acanthocephalus are known for their very small chromosomes with ambiguous morphology, which makes karyotyping difficult. In this study, we performed the first satellitome analysis of three Acanthocephalus species to identify species- and chromosome-specific satellites that could serve as cytogenetic markers.

Prehospital scale to differentiate intracerebral hemorrhage from large-vessel occlusion patients: a prospective cohort study.

Evaluating scales to detect large vessel occlusion (LVO) could aid in considering early referrals to a thrombectomy-capable center in the prehospital stroke code setting. Nevertheless, they entail a significant number of false positives, corresponding to intracranial hemorrhages (ICH). Our study aims to identify easily collectible variables for the development of a scale to differentiate patients with ICH from LVO.

YAT2150 is irresistible in Plasmodium falciparum and active against Plasmodium vivax and Leishmania clinical isolates.

We recently characterized the potent antiplasmodial activity of the aggregated protein dye YAT2150, whose presumed mode of action is the inhibition of protein aggregation in the malaria parasite. Using single-dose and ramping methods, assays were done to select Plasmodium falciparum parasites resistant to YAT2150 concentrations ranging from 3× to 0.25× the in vitro IC of the compound (in the two-digit nM range) and performed a cross-resistance assessment in P.

A remote monitoring approach for coastal engineering projects.

High costs and project-based (short-term) financing mean that coastal engineering projects are often undertaken in the absence of appropriate post-construction monitoring programmes. Consequently, the performance of shoreline-stabilizing structures or beach nourishments cannot be properly quantified. Given the high value of beaches and the increase in erosion problems and coastal engineering responses, managers require as much accurate data as possible to support efficient decision-making.

Cushing syndrome.

Cushing syndrome (CS) is a constellation of signs and symptoms caused by excessive exposure to exogenous or endogenous glucocorticoid hormones. Endogenous CS is caused by increased cortisol production by one or both adrenal glands (adrenal CS) or by elevated adrenocorticotropic hormone (ACTH) secretion from a pituitary tumour (Cushing disease (CD)) or non-pituitary tumour (ectopic ACTH secretion), which stimulates excessive cortisol production. CS is associated with severe multisystem morbidity, including impaired cardiovascular and metabolic function, infections and neuropsychiatric disorders, which notably reduce quality of life.
