The mechanisms underlying the cardiac effects of modified citrus pectin in obese rats with myocardial ischemia: Role of galectin-3.

Background: Modified citrus pectin (MCP) is used as a nutritional supplement that inhibits galectin-3 activity, a central player in the cardiac damage associated with different pathological situations. In fact, we have previously observed that MCP improved cardiac function in obese infarcted rats that was associated with a reduction in cardiac fibrosis. Therefore, the aim of the present study was to further explore whether this effect could involve the modulation of gene expression of ECM components and their mediators as well as whether it could affect another two mechanisms involved in cardiac damage: mitochondrial dynamics and autophagic flux.

The incidence of HIV-2 infection in Spain is declining - a registry data analysis.

Objectives: HIV-2 infection is a neglected disease caused by a human retrovirus that causes AIDS more slowly than HIV-1. Infection with HIV-2 is endemic in West Africa. Given its differential features, guidelines recommend ruling out HIV-2 infection in all newly diagnosed HIV-seropositive individuals.

Clustering COVID-19 ARDS patients through the first days of ICU admission. An analysis of the CIBERESUCICOVID Cohort.

Background: Acute respiratory distress syndrome (ARDS) can be classified into sub-phenotypes according to different inflammatory/clinical status. Prognostic enrichment was achieved by grouping patients into hypoinflammatory or hyperinflammatory sub-phenotypes, even though the time of analysis may change the classification according to treatment response or disease evolution. We aimed to evaluate when patients can be clustered in more than 1 group, and how they may change the clustering of patients using data of baseline or day 3, and the prognosis of patients according to their evolution by changing or not the cluster.

Transcription levels of hes and their involvement in the biofilm formation of Shiga toxin-producing Escherichia coli O91.

Shiga toxin-producing Escherichia coli (STEC) are recognized as being responsible for many cases of foodborne diseases worldwide. Cattle are the main reservoir of STEC, shedding the microorganisms in their feces. The serogroup STEC O91 has been associated with hemorrhagic colitis and hemolytic uremic syndrome.

Analysis of Updates in Multiple Myeloma Treatment and Management.

Introduction: During the past two decades, new therapeutic agents have greatly improved the treatment landscape in multiple myeloma (MM). Treatments such as proteasome inhibitors, immunomodulatory agents, targeted monoclonal antibody therapy, and chimeric antigen receptor (CAR) T-cell therapy have improved outcomes with less toxicity. Advances in laboratory testing have accompanied this change, performing faster and more accurate assessments of treatment response.

Hyposalivation but not Sjögren's syndrome associated with microbial dysbiosis in women.

Background: Saliva modulates the environment of the oral biofilm through pH buffer, microbial attachment to host surfaces, and nutritional source. The ecology of stress occurs when a physical factor adversely impacts an ecosystem or its biotic components. Therefore, reduced salivary flow can affect oral-host balance.

Burden of refractory and unexplained chronic cough on patients' lives: a cohort study.

Background: Chronic cough (cough lasting for ≥8 weeks) can lead to significant impairment in quality of life (QoL). Using patient-reported outcomes, this cohort study assessed the perceived impact of chronic cough on QoL and everyday life in patients from outpatient hospital clinics with refractory chronic cough (RCC) or unexplained chronic cough (UCC).

Methods: This was a multicentre, non-interventional survey study.

FIP1L1-PDGFRA Clonal Hypereosinophilic Syndrome With Eosinophilic Myocarditis and Intracardiac Thrombus.

A 45-year-old man from El Salvador with no past medical history presented with cough and chest pain. Investigations revealed 60% peripheral eosinophilia (absolute count 12.3 K/uL).

Effect of resistance exercise training on plasma neurofilaments in multiple sclerosis: a proof of concept for future designs.

Multiple sclerosis (MS) is a dysimmune and neurodegenerative disease of the central nervous system that continues to be one of the main causes of non-traumatic disability in young people despite the recent availability of highly effective drugs. Exercise-based interventions seem to have a positive impact on the course of the disease although pathophysiological mechanisms responsible for this benefit remain unclear. This is a longitudinal study to examine the effects of a short-term training program on neurofilament plasma levels, a biomarker of axonal destruction, measured using the ultrasensitive single molecule array (SiMoA).

Effects of Gestational Intermittent Hypoxia on Placental Morphology and Fetal Development in a Murine Model of Sleep Apnea.

Obstructive sleep apnea (OSA) during pregnancy is characterized by episodes of intermittent hypoxia (IH) during sleep, resulting in adverse health outcomes for mother and offspring. Despite a prevalence of 8-20% in pregnant women, this disorder is often underdiagnosed.We have developed a murine model of gestational OSA to study IH effects on pregnant mothers, placentas, fetuses, and offspring.

Food allergy in adolescents: validation of the food allergy independent measure and the EuroPrevall food allergy quality of life questionnaire into Spanish.

Background: Different questionnaires have been developed globally to assess and compare the impact of food allergy on the quality of life. The aim of this study was to validate a Spanish translation of the Food Allergy Independent Measure (FAIM) and the EuroPrevall Food Allergy-Quality of Life Questionnaire-Teenage Form (FAQLQ-TF) for adolescents aged 13-17 years.

Methods: Sixty adolescents diagnosed with immunoglobulin E-mediated allergy to food completed the questionnaires.

Treatment with the Olive Secoiridoid Oleacein Protects against the Intestinal Alterations Associated with EAE.

Multiple sclerosis (MS) is a CNS inflammatory demyelinating disease. Recent investigations highlight the gut-brain axis as a communication network with crucial implications in neurological diseases. Thus, disrupted intestinal integrity allows the translocation of luminal molecules into systemic circulation, promoting systemic/brain immune-inflammatory responses.
