RESUMO
This study aimed to validate an inflammation-based risk score in patients with ST-segment elevation myocardial infarction (STEMI) by examining their cytokine profiles. Upon admission, patients were evaluated for systemic inflammation using a risk score that assigned points based on specific biomarkers: 1 point for leukocyte count ≥9.3 × 10³ cells/µL, 2 points for high-sensitivity C-reactive protein (hsCRP) ≥13.0 mg/L, and 3 points for serum albumin ≤3.6 g/dL. Patients were categorized into three groups: no inflammation (0 points, n = 13), mild inflammation (1-2 points, n = 35), and severe inflammation (3-6 points, n = 26). Serum levels of 16 key cytokines were measured. Patients with higher risk scores showed elevated interleukin (IL)-6 levels (19.6 vs. 8.5 vs. 6.8 pg/mL; P = 0.021) and decreased interferon-γ-induced protein-10 (IP-10) levels (73.4 vs. 68.8 vs. 112.2 pg/mL; P = 0.011). IL-6 was positively correlated with hsCRP (ρ 0.307) and negatively correlated with albumin (ρ -0.298), while IP-10 was negatively correlated with leukocyte count (ρ -0.301). No other cytokines showed significant association with the risk score. Higher inflammation scores were also associated with an increased incidence of major adverse cardiovascular events, particularly acute heart failure. This study underscores the association between the inflammation-based risk score and cytokine levels, specifically IL-6 and IP-10, in patients with STEMI.
RESUMO
Objetivo: Descubrir cuáles son las construcciones sociales en la salud sexual de las mujeres adolescentes de una comunidad rural. Material y Métodos: Estudio cualitativo fenomenológico hermenéutico, donde participaron mujeres adolescentes de 14 a 19 años, pertenecientes a la comunidad, El Molino, Ojuelos Jalisco, México. A través de un muestreo por cadena de referencia, se realizaron entrevistas fenomenológicas, transcritas de manera artesanal y anal-izadas mediante el "círculo hermenéutico Heiderggeriano". Se obtuvo la autorización mediante el consentimiento informado, así como el asentimiento por parte de los tutores. Se cumple un rigor metodológico a través de la trasparencia, transferibilidad, credibilidad y autenticidad. Resultados: Se realizaron 10 entrevistas afines a 10 adolescentes y se determinaron 6 unidades de significado a partir del análisis hermenéutico, de los cuales tres son ónticas; una realidad palpable a la desinformación sobre vida sexual, ideologías paternales adiestradas y falo centrismo como base central en la dinámica social. Y tres son ontológicas; Sesgo educativo, Discurso del lenguaje culturizado, finalmente tabúes y estigmas familiares. Conclusión: Las mujeres adolescentes de una comunidad rural viven una doble moral social. Así se demuestra un ineficiente conocimiento sobre salud sexual hasta ser un tema intrascendente, los padres son quienes influyen y toman decisiones sobre la educación, autonomía y forma de pensar.
Objective: Discover what the social constructions in the sexual health of adolescent women in a rural community. Material and Methods: A qualitative hermeneutic phenomenological study, involving adolescent women from 14 to 19 years old, belonging to the community, El Molino Ojuelos Jalisco, México. Through a reference chain sampling, phenomenological inter-views were carried out, transcribed by hand and analyzed through the "Heiderggerian herme-neutic circle". Authorization was obtained through informed consent, as well as the assent of the tutors. Complying with methodological rigor through transparency, transferability, credibility and authenticity. Results: 10 related interviews were carried out with 10 adolescents, and 6 units of meaning were determined from the hermeneutic analysis, of which three are ontic; a palpable reality to the ignorance of contraceptive methods, trained paternal ideologies and phallocentrism as a central basis in social dynamics. And three are ontological; Educational bias, cultured language discourse, finally taboos and family stigmas. Conclusion: Adolescent women from a rural community experience a double social standard. Thus, demonstrating an inefficient knowledge about sexual health until it is an insignificant issue, parents are the ones who influence and make decisions about education, autonomy and way of thinking

Prompt diagnosis of ST-segment elevation myocardial infarction (STEMI) is essential for initiating timely treatment. MicroRNAs have recently emerged as biomarkers in cardiovascular diseases. This study aimed to evaluate the discriminatory capacity of serum microRNAs in identifying an ischemic origin in patients presenting with chest discomfort to the Emergency Department. The study included 98 participants (78 with STEMI and 20 with nonischemic chest discomfort). Significant differences in the expression levels of miR-133b, miR-126, and miR-155 (but not miR-1, miR-208, and miR-208b) were observed between groups. miR-133b and miR-155 exhibited 97% and 93% sensitivity in identifying STEMI patients, respectively. miR-126 demonstrated a specificity of 90% in identifying STEMI patients. No significant associations were found between microRNAs and occurrence of major adverse cardiovascular events (MACE). However, patients with MACE had higher levels of interleukin (IL)-15, IL-21, IFN-γ-induced protein-10, and N-terminal pro B-type natriuretic peptide compared to non-MACE patients. Overall, there were significant associations among the expression levels of microRNAs. However, microRNAs did not demonstrate associations with either inflammatory markers or cardiovascular risk scores. This study highlights the potential of microRNAs, particularly miR-133b and miR-126, as diagnostic biomarkers for distinguishing patients with STEMI from those presenting with nonischemic chest discomfort to the Emergency Department.
RESUMO
Through screening of rhizobacteria, species that effectively suppress phytopathogens and/or promote plant growth are found. Genome sequencing is a crucial step in obtaining a complete characterization of microorganisms for biotechnological applications. This study aimed to sequence the genomes of four rhizobacteria that differ in their inhibition of four root pathogens and in their interaction with chili pepper roots to identify the species and analyze differences in the biosynthetic gene clusters (BGCs) for antibiotic metabolites and to determine possible phenotype-genotype correlations. Results from sequencing and genome alignment identified two bacteria as Paenibacillus polymyxa, one as Kocuria polaris, and one that was previously sequenced as Bacillus velezensis. Analysis with antiSMASH and PRISM tools showed that B. velezensis 2A-2B, the strain with the best performance of referred characteristics, had 13 BGCs, including those related to surfactin, fengycin, and macrolactin, not shared with the other bacteria, whereas P. polymyxa 2A-2A and 3A-25AI, with up to 31 BGCs, showed lower pathogen inhibition and plant hostility; K. polaris showed the least antifungal capacity. P. polymyxa and B. velezensis had the highest number of BGCs for nonribosomal peptides and polyketides. In conclusion, the 13 BGCs in the genome of B. velezensis 2A-2B that were not present in the other bacteria could explain its effective antifungal capacity and could also contribute to its friendly interaction with chili pepper roots. The high number of other BGCs for nonribosomal peptides and polyketide shared by the four bacteria contributed much less to phenotypic differences. IMPORTANCE To advance the characterization of a microorganism as a biocontrol agent against phytopathogens, it is highly recommended to analyze the potential of the profile of secondary metabolites as antibiotics that it produces to counteract pathogens. Some specific metabolites have positive impacts in plants. By analyzing sequenced genomes with bioinformatic tools, such as antiSMASH and PRISM, outstanding bacterial strains with high potential to inhibit phytopathogens and/or promote plant growth can be quickly selected to confirm and expand our knowledge of BGCs of great value in phytopathology.

Objective: The aim of the study was to assess whether a recent SARS-CoV-2 infection could by itself be a risk or prognostic factor for ST-segment elevation myocardial infarction (STEMI). Method: An observational study in unvaccinated patients with STEMI confirmed by cardiac catheterization was conducted. A recent or concurrent SARS-CoV-2 infection was identified by the presence of serum IgG against the nucleocapsid protein, or a positive polymerase chain reaction test on nasopharyngeal swabs. Baseline cardiovascular risk factors, clinical STEMI severity, main catheterization findings, and occurrence of major adverse cardiovascular events (MACE) during hospitalization were compared between study subgroups. Results: Of a total of 89 patients recruited, 14 (16%) had a recent SARS-CoV-2 infection. Patients with STEMI and recent SARS-CoV-2 infection had a markedly lower frequency of high blood pressure (20% versus 55%; P = 0.03) as well as a tendency to have fewer comorbidities. Regarding the clinical presentation, there were no differences in the severity of the STEMI. Furthermore, the main findings during cardiac catheterization including the atherosclerotic burden and the number of vessels affected, as well as the occurrence of MACE during follow-up, were not significantly different between the groups. Conclusions: A recent SARS-CoV-2 infection appears to facilitate the triggering of STEMI, as these patients have fewer traditional cardiovascular risk factors than their uninfected counterparts. However, this does not seem to affect the clinical presentation or the in-hospital course of STEMI patients.
RESUMO
Coronavirus disease 2019 (COVID-19) is associated with pulmonary embolism, a condition mechanistically related to vascular endothelial growth factor (VEGF). Our objective was to identify whether VEGF levels, measured at hospital admission, may predict the occurrence of pulmonary embolism (and other thrombosis) during hospitalization. Of a total of 139 patients included in the study, a pulmonary embolism occurred in 4%, other thrombosis in 16%, and 80% remained thrombus free. Clinical and laboratory data at admission were similar among groups. VEGF levels were elevated in COVID-19 patients compared with 38 healthy controls (50.7 versus 15.0 pg/mL; P < 0.001), with an area under the receiver operating characteristic curve of 0.776. At a cutoff point >15.7 pg/mL, VEGF showed 64.7% sensitivity, 92.1% specificity, and a positive likelihood ratio of 8.2 to discriminate COVID-19. In COVID-19, VEGF levels were not different in patients with pulmonary embolism, other thrombosis, and thrombus-free patients (15.0 versus 84.0 versus 48.5 pg/mL, respectively; P = 0.19). VEGF correlated with C-reactive protein (ρ = 0.25), fibrinogen (ρ = 0.28), ferritin (ρ = 0.18), and the neutrophil-to-lymphocyte ratio (ρ = 0.20). Our study showed that VEGF is elevated in sera from patients with COVID-19 on arrival at the hospital and its levels correlate with inflammatory markers, although they are unable to predict the appearance of pulmonary embolism during hospitalization.

Objetivo. Determinar la presencia de rotavirus y norovirus en agua para consumo humano en una localidad de Bogotá. Materiales y métodos. Se recolectaron ocho muestras de agua por semana en ocho lugares diferentes del predio en estudio. Para determinar la presencia del genoma viral, las muestras se ultrafiltraron y se hizo detección viral por medio de la técnica RT-PCR, amplificando un segmento del gen VP6 del rotavirus y un segmento del ORF2 del norovirus. Este estudio se llevó a cabo en una institución universitaria ubicada en una zona periurbana cercana a Bogotá, a 45 km del acueducto que surte de agua al predio. La zona se encuentra rodeada por fincas con ganado lechero, centros comerciales y cuatro cementerios. El agua se recolectó en recipientes de polipropileno. En total, fueron 64 muestras de cinco litros de agua cada una. Resultados. La presencia viral fue de 12,5 %, encontrándose rotavirus en cuatro y norovirus en cuatro de las 64 muestras colectadas. Además de presentar la importancia de la presencia viral en agua para consumo humano, en este documento se discute el significado que tiene el encontrar solo segmentos virales y no la partícula viral completa e infecciosa.
Objective: To determine the presence of rotavirus and norovirus in drinking water in a northern neighborhood in Bogotá, Colombia. Materials and methods: Eight weekly samples of water were collected and ultrafiltered in order to detect the viral genome presence. The technique used for detection of genome segments was RT-PCR. VP6 gene from rotavirus and ORF2 segment from norovirus were selected in order to find the virus in the water. This study was performed in a higher education institution located in a periurban zone near Bogotá, 45 km away from the aqueduct that services the area. The zone is surrounded by dairy cattle farms, malls and four cemeteries. Water was collected in clean polypropylene containers. There were a total of 64 samples of 5 liters of water each. Results: Viral segments were found in 12.5% of the samples. We found rotavirus in four samples and norovirus in another 4. Besides discussing the importance of viral contamination in drinking water, we discussed the meaning of finding only viral segments and not complete and infectious viral particles.
