Nasal myiasis: an infrequent cause of sinusitis in a critical care patient.

A patient in his 70s, admitted to the cardiac intensive care unit with cardiogenic shock, unexpectedly presented with nasal myiasis during a workup for persistently elevated inflammatory markers. CT scans revealed sinusitis and bronchial secretions, while bronchoscopy identified mucus with positive pathogen testing. Nasal endoscopy was crucial in diagnosing myiasis, and immediate mechanical removal of larvae was performed.

Genome-wide analyses provide insights into genetic variation, phylo- and co-phylogenetic relationships, and biogeography of the entomopathogenic nematode genus Heterorhabditis.

Multigene, genus-wide phylogenetic studies have uncovered the limited taxonomic resolution power of commonly used gene markers, particularly of rRNA genes, to discriminate closely related species of the nematode genus Heterorhabditis. In addition, conflicting tree topologies are often obtained using the different gene markers, which limits our understanding of the phylo- and co-phylogenetic relationships and biogeography of the entomopathogenic nematode genus Heterorhabditis. Here we carried out phylogenomic reconstructions using whole nuclear and mitochondrial genomes, and whole ribosomal operon sequences, as well as multiple phylogenetic reconstructions using various single nuclear and mitochondrial genes.

The Anticipated Stigma and Concealment Questionnaire (ASCQ): Psychometric properties of a Spanish version in a Chilean sample of brain injury survivors.

Stigma represents a major obstacle in rehabilitation and community reintegration after brain injury. However, appropriate tools to measure stigma in Spanish-speaking countries are lacking. This study examined the psychometric properties of the Spanish version of the Anticipated Stigma and Concealment Questionnaire (ASCQ).

Prevalence of Crown Resorption in Amelogenesis Imperfecta due to Junctional Epidermolysis Bullosa.

Introduction: Junctional epidermolysis bullosa (JEB) is a rare genetic disease manifesting with skin and mucosal blistering. As part of the JEB, patients present with syndromic amelogenesis imperfecta (AI). Reports have described external crown resorption (ECR) in the teeth of patients with JEB, but its prevalence is unknown.

Homeostats: The hidden rulers of ion homeostasis in plants.

Ion homeostasis is a crucial process in plants that is closely linked to the efficiency of nutrient uptake, stress tolerance and overall plant growth and development. Nevertheless, our understanding of the fundamental processes of ion homeostasis is still incomplete and highly fragmented. Especially at the mechanistic level, we are still in the process of dissecting physiological systems to analyse the different parts in isolation.

Experiences and needs of unaccompanied irregular migrant minors who arrive in Spain on small boats: A qualitative study.

The European Union receives thousands of unaccompanied irregular migrant minors every year, but little is known about their life experiences during the migration process. The aim of this study is to describe their experiences as minors when they arrived in Spain in small boats, which will help to understand their psychosocial and health needs. A descriptive qualitative study was undertaken.

What Are the Barriers, Facilitators and Interventions Targeting Help-Seeking Behaviours for Common Mental Health Problems in Adolescents? A Systematic Review.

Background: Increasing rates of mental health problems among adolescents are of concern. Teens who are most in need of mental health attention are reluctant to seek help. A better understanding of the help-seeking in this population is needed to overcome this gap.

Developing machine-learning-based amyloidogenicity predictors with Cross-Beta DB.

Introduction: The importance of protein amyloidogenesis, associated with various diseases and functional roles, has driven the creation of computational predictors of amyloidogenicity. The accuracy of these predictors, particularly those utilizing artificial intelligence technologies, heavily depends on the quality of the data.

Methods: We built Cross-Beta DB, a database containing high-quality data on known cross-β amyloids formed under natural conditions.

Effect of temperature on circadian clock functioning of trees in the context of global warming.

Plant survival in a warmer world requires the timely adjustment of biological processes to cyclical changes in the new environment. Circadian oscillators have been proposed to contribute to thermal adaptation and plasticity. However, the influence of temperature on circadian clock performance and its impact on plant behaviour in natural ecosystems are not well-understood.

Sociodemographic profiles of Indigenous households in the 1991, 2000, and 2010 censuses.

This article analyzes the sociodemographic composition of the Indigenous population in Brazil in the 1991, 2000, and 2010 demographic censuses, in addition to investigating inequalities in access to basic sanitation and electricity based on the 2010 Census. A methodology is proposed that classifies households with Indigenous residents as "homogeneous", "mixed" with an Indigenous in the category "household head", and mixed with a non-Indigenous in the category "household head". Regional and situational differences overlapped with differences by type of household and location, with better conditions in urban than rural areas and in the Southeast and South.

Brainstem C1 neurons mediate heart failure decompensation and mortality during acute salt loading.

Aims: Heart failure (HF) is an emerging epidemic worldwide. Despite advances in treatment, the morbidity and mortality rate of HF remain high, and the global prevalence continues to rise. Common clinical features of HF include cardiac sympathoexcitation, disordered breathing, and kidney dysfunction; kidney dysfunction strongly contributes to sodium retention and fluid overload, leading to poor outcomes of HF patients.

Association between demographic, clinical characteristics and severe complications by SARS-CoV-2 infection in a community-based healthcare network in Chile.

Background: Most of the evidence on risk factors for COVID-19 complications comes from North America or Europe with very little research from Latin-America. We aimed to evaluate the association between sociodemographic, clinical factors and the risk of COVID-19 complications among adults in Chile, the fifth Latin-American country with more COVID-19 reported cases since de beginning of the Pandemic.

Methods: A retrospective population-based cohort study using data from electronic health records from a large Primary Care Network, linked to national hospital, immunization, Covid-19 PCR surveillance, mortality and birth records.

Epibiotic bacterial community composition varies during different developmental stages of Octopus mimus: Study of cultivable representatives and their secondary metabolite production.

Marine microbial communities colonizing the skin of invertebrates constitute the primary barrier between host and environment, potentially exerting beneficial, neutral, or detrimental effects on host fitness. To evaluate the potential contribution of epibiotic bacteria to the survival of early developmental stages of Octopus mimus, bacterial isolates were obtained from eggs, paralarvae, and adults. Their enzymatic activities were determined, and antibacterial properties were assessed against common marine pathogens.

Curcumin Improves Hippocampal Cell Bioenergetics, Redox and Inflammatory Markers, and Synaptic Proteins, Regulating Mitochondrial Calcium Homeostasis.

Mitochondria produces energy through oxidative phosphorylation (OXPHOS), maintaining calcium homeostasis, survival/death cell signaling mechanisms, and redox balance. These mitochondrial functions are especially critical for neurons. The hippocampus is crucial for memory formation in the brain, which is a process with high mitochondrial function demand.

Neurogastroenterology and motility disorders in patients with cirrhosis.

Neurogastroenterology and motility disorders are complex gastrointestinal conditions that are prevalent worldwide, particularly affecting women and younger individuals. These conditions significantly impact the quality of life of people suffering from them. There is increasing evidence linking these disorders to cirrhosis, with a higher prevalence compared to the general population.

Pharmacokinetics of Methadone in Adult Patients Undergoing Cardiac Surgery With Cardiopulmonary Bypass.

Background: Cardiopulmonary bypass (CPB) induces profound physiological changes that may alter the pharmacokinetics of methadone. We aimed to describe the pharmacokinetics of an intravenous bolus of methadone racemate in adult patients undergoing heart surgery with CPB.

Methods: We prospectively studied 29 patients aged 45 to 75 years scheduled for cardiac surgery with CPB who received methadone 0.

Safety and efficacy of mesenchymal stromal cells mitochondria transplantation as a cell-free therapy for osteoarthritis.

Objective: The inflammatory responses from synovial fibroblasts and macrophages and the mitochondrial dysfunction in chondrocytes lead to oxidative stress, disrupt extracellular matrix (ECM) homeostasis, and accelerate the deterioration process of articular cartilage in osteoarthritis (OA). In recent years, it has been proposed that mesenchymal stromal cells (MSC) transfer their functional mitochondria to damaged cells in response to cellular stress, becoming one of the mechanisms underpinning their therapeutic effects. Therefore, we hypothesize that a novel cell-free treatment for OA could involve direct mitochondria transplantation, restoring both cellular and mitochondrial homeostasis.

BK channels mediate a presynaptic form of mGluR-LTD in the neonatal hippocampus.

BK channels can control neuronal function, but their functional relevance in activity-dependent changes of synaptic function remains elusive. Here, we report that repetitive low-frequency stimulation activates BK channels through 12(S)HPETE, an arachidonic acid metabolite, produced downstream of postsynaptic metabotropic glutamate receptors (mGluRs) to trigger long-term depression (LTD) at CA3-CA1 synapses in hippocampal slices from P7-P10 mice. Activation of BK channels is subunit specific, as paxilline but not iberiotoxin blocked mGluR-LTD.

Optogenetic control of horizontally acquired genes prevent stuck fermentations in yeast.

Nitrogen limitations in the grape must be the main cause of stuck fermentations during the winemaking process. In , a genetic segment known as region A, which harbors 12 protein-coding genes, was acquired horizontally from a phylogenetically distant yeast species. This region is mainly present in the genome of wine yeast strains, carrying genes that have been associated with nitrogen utilization.

Carotid bodies mediate glial cell activation and neuroinflammation in the NTS following long-term intermittent hypoxia: role in cardiorespiratory dysfunction.

Chronic intermittent hypoxia (CIH), the main feature of obstructive sleep apnea, heightened chemosensory discharges of the carotid body (CB), which contributes to potentiate the ventilatory hypoxic response and elicits hypertension. We aimed to determine: 1) whether the persistence of cardiorespiratory alterations found in long-term CIH depend on the inputs from the CB and, 2) in what extension the activation of glial cells and neuroinflammation in the caudal region of the nucleus of the Solitary Tract (NTS) requires functional CB chemosensory activity. To evaluate these hypotheses, we exposed male mice to CIH for 60 days.
