[Good practices in epidemiological surveillance for the sustainability of measles, rubella, and congenital rubella syndrome elimination in El Salvador, 2019-2023Boas práticas de vigilância epidemiológica para a sustentabilidade da eliminação do sarampo, da rubéola e da síndrome da rubéola congênita em El Salvador, 2019-2023].

Objective: Describe good practices in epidemiological surveillance implemented in El Salvador between 2019 and 2023 to sustain the elimination of measles, rubella, and congenital rubella syndrome.

Methods: Special descriptive report on the implementation of good epidemiological and laboratory surveillance practices for measles, rubella, and congenital rubella syndrome from 2019 to 2023.

Results: During the period 2019 to 2023, El Salvador reported no confirmed cases of measles, rubella, or congenital rubella syndrome.

Heavy metal concentrations in sharks, rays and chimaeras from the western Mediterranean Sea.

The potential bioaccumulation of pollutants, such as heavy metals, may pose a threat to the western Mediterranean chondrichthyans and human consumers. Therefore, the first extensive assessment of cadmium (Cd), lead (Pb), and copper (Cu) concentrations in the muscle tissue of 17 species of sharks, rays, and chimaeras in this region was conducted via Microwave Assisted Extraction (MAE) and Graphite Furnace Atomic Absorption Spectrometry (GFAAS). Significant differences between species were observed, particularly related to the rabbit fish (Chimaera monstrosa) and the velvet belly lantern shark (Etmopterus spinax), which exceeded the European Union (EU) Commission Regulation 2023/915 threshold of Cd.

T-Cell MyD88 Is a Novel Regulator of Cardiac Fibrosis Through Modulation of T-Cell Activation.

Background: Cardiac inflammation in heart failure is characterized by the presence of damage-associated molecular patterns, myeloid cells, and T cells. Cardiac damage-associated molecular patterns provide continuous proinflammatory signals to myeloid cells through TLRs (toll-like receptors) that converge onto the adaptor protein MyD88 (myeloid differentiation response 88). These induce activation into efficient antigen-presenting cells that activate T cells through their TCR (T-cell receptor).

Unravelling glioblastoma heterogeneity by means of single-cell RNA sequencing.

Glioblastoma (GBM) is the most invasive and deadliest brain cancer in adults. Its inherent heterogeneity has been designated as the main cause of treatment failure. Thus, a deeper understanding of the diversity that shapes GBM pathobiology is of utmost importance.

[Basics of primary immunodeficiencies].

Primary immunodeficiencies (PID) are a heterogeneous group of inherited disorders, the etiology are the defects in the development or function of the immune system. The principal PID manifestations are the infections in early age, malignancy and diseases of immune dysregulation as autoimmunity and allergy. PIDs are genetics disorders and most of them are inherited as autosomal recessive, also this group of diseases is more prevalent in males and in childhood.

Quantitative assessment of global hepatic glycolysis in patients with cirrhosis and normal controls using 18F-FDG-PET/CT: a pilot study.

Objective: To compare differences in global measures of hepatic metabolism between control subjects and subjects with cirrhosis.

Materials And Methods: FDG-PET/CT scans of 33 subjects either without or with cirrhosis were analyzed retrospectively and classified as follows: group 1 includes subjects without cirrhosis or extrahepatic malignancy (1a) (n=11) and subjects without cirrhosis but with history of extrahepatic malignancy (1b) (n=10); group 2 includes subjects with cirrhosis and history of extrahepatic malignancy (n=12). Subjects with focal hepatic lesions, prior hepatic surgery, co-existing liver pathology, or who received chemotherapy or radiation therapy within the last 6 months were excluded.

Measurement characteristics of the pediatric asthma health outcome measure.

Introduction: The Pediatric Asthma Health Outcome Measure (PAHOM) was designed to measure quality-adjusted life years (QALYs) in children with asthma. Our objective was to compare parent- and child-reported PAHOM scores to each other, to parent-reported scores on the Juniper Asthma Control Questionnaire (ACQ), and to physician-rated asthma control.

Methods: A convenience sample of primarily African-American parent-child dyads (N = 261) was recruited from asthma clinics between May 2008 and May 2010.
