Multimorbidity, social determinants and intersectionality in chronic patients. Results from the EpiChron Cohort.

Background: Multimorbidity is influenced in an interconnected way, both in extent and nature, by the social determinants of health. We aimed at implementing an intersectional approach to analyse the association of multimorbidity with five important axes of social inequality (i.e.

Achieving the UNAIDS goals by 2030 in people living with HIV: A simulation model to support the prioritization of health care interventions.

Objective: We simulated the impact of implementing different health interventions to improve the HIV continuum of care for people diagnosed, on treatment, and virologically suppressed in Spain for the 2020-2030 period.

Methods: The model was carried out in four phases involving a multidisciplinary expert panel: (1) literature review; (2) selection/definition of the interventions and their effectiveness; (3) consensus meeting; and (4) development of an analytical decision model to project the impact of implementing/strengthening these interventions to improve the HIV continuum of care, corresponding to 2017-2019 (87% diagnosed, 97% on treatment, 90% with viral suppression), through the creation of different scenarios for 2020-2030. A total of 19 interventions were selected based on expanding the offer of HIV rapid tests and implementing training/peer programmes, electronic alerts, multidisciplinary care, and mHealth, among others.

Experimental and Bioinformatic Insights into the Effects of Epileptogenic Variants on the Function and Trafficking of the GABA Transporter GAT-1.

In this article, we identified a novel epileptogenic variant (G307R) of the gene , which encodes the GABA transporter GAT-1. Our main goal was to investigate the pathogenic mechanisms of this variant, located near the neurotransmitter permeation pathway, and compare it with other variants located either in the permeation pathway or close to the lipid bilayer. The mutants G307R and A334P, close to the gates of the transporter, could be glycosylated with variable efficiency and reached the membrane, albeit inactive.

Lifestyle and Health-Related Quality of Life Relationships Concerning Metabolic Disease Phenotypes on the Nutrimdea Online Cohort.

Obesity, diabetes and cardiovascular events are non-communicable diseases (NCDs) directly related to lifestyle and life quality. Rises on NCDs rates are leading to increases in early deaths concerning metabolic morbidities. Health-related quality of life (HRQoL) has been described as a subjective perception about the influence of health and personal features on human well-being.

Progression of metabolic syndrome and associated cardiometabolic risk factors from prepuberty to puberty in children: The PUBMEP study.

Introduction: Metabolic syndrome (MetS) is a cluster of clinical and metabolic alterations related to the risk of cardiovascular diseases (CVD). Metabolic changes occurring during puberty, especially in children with overweight and obesity, can influence the risk of developing chronic diseases, especially CVD.

Methods: Longitudinal study based on the follow-up until puberty of a cohort of 191 prepubertal Spanish boys and girls without congenital, chronic, or inflammatory diseases: undernutrition: or intake of any drug that could alter blood glucose, blood pressure, or lipid metabolism.

Serum levels of the novel adipokine isthmin-1 are associated with obesity in pubertal boys.

Objectives: To evaluate whether there is an association between the serum levels of the novel insulin-like adipokine isthmin-1 (ISM1) and obesity-related phenotypes in a population of Spanish children and to investigate the plausible molecular alterations behind the alteration of the serum levels of this protein in children with obesity.

Methods: The study population is a sub-cohort of the PUBMEP research project, consisting of a cross-sectional population of 119 pubertal children with overweight (17 boys, 19 girls), obesity (20 boys, 25 girls), and normal weight (17 boys, 21 girls). All subjects were classified into experimental groups according to their sex, obesity, and insulin resistance (IR) status.

Background: Online health data collection has gained a reputation over the last years to record and process information about health issues for implementing digital health.

Objective: The research aim was to appraise two online methods (open and rewarded) to collect information about HRQoL and nutritional well-being and to compare the results between both surveyed populations.

Methods: This cross-sectional study is framed on the NUTRiMDEA project.

Metabolomics in Cell Biology.

Metabolomics has long been used in a biomedical context. The most typical samples are body fluids in which small molecules can be detected and quantified using technologies such as Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS). Many studies, in particular in the wider field of cancer research, are based on cellular models.

Vitamin D Deficiency and COVID-19: A Biological Database Study on Pathways and Gene-Disease Associations.

Vitamin D (VD) is a fat-soluble vitamin, and pivotal for maintaining health. Several genetic markers have been related to a deficient VD status; these markers could confer an increased risk to develop osteoporosis and other chronic diseases. A VD deficiency could also be a determinant of a severe COVID-19 disease.

Longitudinal associations between cardiovascular biomarkers and metabolic syndrome during puberty: the PUBMEP study.

Unlabelled: Puberty has been described as a life stage of considerable metabolic risk specially for those with obesity. The low-grade systemic inflammatory status associated with obesity could be one of the connections with metabolic syndrome (MetS). Thus, we aimed to assess the relationship between inflammatory and cardiovascular biomarkers and the development of MetS during puberty.

HTLV-2 Enhances CD8 T Cell-Mediated HIV-1 Inhibition and Reduces HIV-1 Integrated Proviral Load in People Living with HIV-1.

People living with HIV-1 and HTLV-2 concomitantly show slower CD4 T cell depletion and AIDS progression, more frequency of the natural control of HIV-1, and lower mortality rates. A similar beneficial effect of this infection has been reported on HCV coinfection reducing transaminases, increasing the spontaneous clearance of HCV infection and delaying the development of hepatic fibrosis. Given the critical role of CD8 T cells in controlling HIV-1 infection, we analysed the role of CD8 T cell-mediated cytotoxic activity in coinfected individuals living with HIV-1.

Potential usefulness of Mediterranean diet polyphenols against COVID-19-induced inflammation: a review of the current knowledge.

The Mediterranean diet is a dietary pattern typical of the populations living in the Mediterranean basin during the 50s-60s of the last century. This diet has demonstrated beneficial effects in the prevention of several pathologies such as cardiovascular diseases, metabolic syndrome, or several cancer types, at least in part, due to its antioxidant compounds. Since the COVID-19 pandemic started, different authors have been studying the effects of certain dietary habits on the presence of COVID-19 and its severity, and the Mediterranean diet is one of them.

Approaches to STI Prevention and Control in a Highly Decentralized State: An Integrative Review.

The Spanish health system is highly decentralized and Autonomous Regions (AR) are responsible for managing and implementing the National Strategic Plan for Prevention and Control of HIV and other Sexually Transmitted Infections (STI) (2013-2020) via autonomous plans adapted to the characteristics of each region. The aim of this study is to report on actions taken to specifically address STI prevention and control in the autonomous plans within the mainframe of the National Strategic Plan. An integrative review was performed to analyse the health plans and HIV/STI plans of the Spanish AR during the period of validity of the current National Strategic Plan; 2013-2020.

Hypoxia-Inducible Factor 2 Alpha (HIF2α) Inhibitors: Targeting Genetically Driven Tumor Hypoxia.

Tumors driven by deficiency of the VHL gene product, which is involved in degradation of the hypoxia-inducible factor subunit 2 alpha (HIF2α), are natural candidates for targeted inhibition of this pathway. Belzutifan, a highly specific and well-tolerated HIF2α inhibitor, recently received FDA approval for the treatment of nonmetastatic renal cell carcinomas, pancreatic neuroendocrine tumors, and central nervous system hemangioblastomas from patients with von Hippel-Lindau disease, who carry VHL germline mutations. Such approval is a milestone in oncology; however, the full potential, and limitations, of HIF2α inhibition in the clinic are just starting to be explored.

Crosstalk between CXCR4/ACKR3 and EGFR Signaling in Breast Cancer Cells.

A better understanding of the complex crosstalk among key receptors and signaling pathways involved in cancer progression is needed to improve current therapies. We have investigated in cell models representative of the major subtypes of breast cancer (BC) the interplay between the chemokine CXCL12/CXCR4/ACKR3 and EGF receptor (EGFR) family signaling cascades. These cell lines display a high heterogeneity in expression profiles of CXCR4/ACKR3 chemokine receptors, with a predominant intracellular localization and different proportions of cell surface CXCR4+, ACKR3+ or double-positive cell subpopulations, and display an overall modest activation of oncogenic pathways in response to exogenous CXCL12 alone.

Preliminary evaluation of the efficacy of quantum molecular resonance coablative radiofrequency and microdiscectomy.

The aim of this study was to determine whether there exists a difference in efficacy in the treatment of lumbar radiculopathy with quantum molecular resonance coablative radiofrequency and quantum molecular resonance coablative radiofrequency and percutaneous microdiscectomy with grasper forceps (QMRG). A total of 28 patients from La Fe University and Polytechnic Hospital in Valencia were enrolled in a retrospective cohort. Treatment with QMRG significantly improved non-sleep-related and sleep-related outcome measures.

RNF43 mutations predict response to anti-BRAF/EGFR combinatory therapies in BRAF metastatic colorectal cancer.

Anti-BRAF/EGFR therapy was recently approved for the treatment of metastatic BRAF colorectal cancer (mCRC). However, a large fraction of patients do not respond, underscoring the need to identify molecular determinants of treatment response. Using whole-exome sequencing in a discovery cohort of patients with mCRC treated with anti-BRAF/EGFR therapy, we found that inactivating mutations in RNF43, a negative regulator of WNT, predict improved response rates and survival outcomes in patients with microsatellite-stable (MSS) tumors.

Rheological Properties and Stability of Thickeners for Clinical Use.

The adaptation of liquids for patients with dysphagia requires precision and individualization in the viscosities used. We describe the variations of viscosity in water at different concentrations and evolution over time of the three compositions of commercial thickeners that are on the market (starch, starch with gums, and gum). By increasing the concentration in water, the viscosity of gum-based thickeners increases linearly, but it did not reach pudding texture, whereas the viscosity of the starch-based thickeners (alone or mixed with gums) rapidly reaches very thick textures.

Peripheral blood mononuclear cells-expressed miRNA profiles derived from children with metabolic-associated fatty liver disease and insulin resistance.

Background: miRNA have been proposed as potential biomarkers of metabolic diseases.

Objectives: To identify potential miRNA biomarkers of early metabolic-associated fatty liver disease (MAFLD) and/or insulin resistance (IR) in preadolescent children.

Methods: A total of 70 preadolescents, aged 8.

Epigenomic Approaches for the Diagnosis of Rare Diseases.

Rare diseases affect more than 300 million people worldwide. Diagnosing rare diseases is a major challenge as they have different causes and etiologies. Careful assessment of clinical symptoms often leads to the testing of the most common genetic alterations that could explain the disease.

Increased Expression of Alpha-, Beta-, and Gamma-Synucleins in Brainstem Regions of a Non-Human Primate Model of Parkinson's Disease.

Parkinson's disease (PD) is characterized by cell loss in the substantia nigra and the presence of alpha-synuclein (α-syn)-containing neuronal Lewy bodies. While α-syn has received major interest in the pathogenesis of PD, the function of beta- and gamma-synucleins (β-syn and γ-syn, respectively) is not really known. Yet, these proteins are members of the same family and also concentrated in neuronal terminals.

Nutritional Risk Factors Associated with Vasomotor Symptoms in Women Aged 40-65 Years.

Vasomotor symptoms (VMS) are the most common symptoms among menopausal women; these include hot flashes and night sweats, and palpitations often occur along with hot flashes. Some studies in Mexico reported that around 50% of women presented with VMS mainly in the menopausal transition. It has been proven that VMS are not only triggered by an estrogen deficiency, but also by nutritional risk factors.
