ABSTRACT

BACKGROUND: The mRNA-1345 vaccine demonstrated efficacy against RSV disease with acceptable safety in adults ≥60 years in the ConquerRSV trial. Here, humoral immunogenicity results from the trial are presented. METHODS: This phase 2/3 trial randomly assigned adults (≥60 years) to mRNA-1345 50-µg encoding prefusion F (preF) glycoprotein (n = 17,793) vaccine or placebo (n = 17,748). RSV-A and RSV-B neutralizing antibody (nAb) and preF binding antibody (bAb) levels at baseline and day 29 post-vaccination were assessed in a per-protocol immunogenicity subset ([PPIS]; mRNA-1345, n = 1515; placebo, n = 333). RESULTS: Day 29 nAb geometric mean titers (GMTs) increased 8.4-fold against RSV-A and 5.1-fold against RSV-B from baseline. Seroresponses (4-fold rise from baseline) in the mRNA-1345 groups were 74.2% and 56.5% for RSV-A and RSV-B, respectively. Baseline GMTs were lower among participants who met the seroresponse criteria than those who did not. mRNA-1345 induced preF bAbs at day 29, with a pattern similar to nAbs. Day 29 antibody responses across demographic and risk subgroups were generally consistent with the overall PPIS. CONCLUSION: mRNA-1345 enhanced RSV-A and RSV-B nAbs and preF bAbs in adults (≥60 years) across various subgroups, including those at risk for severe disease, consistent with its demonstrated efficacy in the prevention of RSV disease.

ABSTRACT

The objective of this study was to evaluate the safety and efficacy of bermekimab, an IL-1α inhibitor, in the treatment of hidradenitis suppurativa (HS). This study was a phase II, multicenter, open-label study of two dose cohorts of bermekimab in patients with moderate-to-severe HS who are naïve to or have failed prior anti-TNF therapy. Patients with HS (n = 42) were divided into groups A and B based on whether or not they had previously failed an anti-TNF therapy. In group A (n = 24), bermekimab was administered subcutaneously at a dose of 400 mg weekly (13 doses) in patients who had previously failed anti-TNF therapy; in group B (n = 18), bermekimab was administered subcutaneously at a dose of 400 mg weekly (13 doses) in patients who were anti-TNF naïve. Bermekimab, previously found to be effective in treating HS, was evaluated using a subcutaneous formulation in patients with HS naïve to or having failed anti-TNF therapy. There were no bermekimab-related adverse events with the exception of injection site reactions. Bermekimab was effective despite treatment history, with 61% and 63% of patients naïve to and having failed anti-TNF therapy, respectively, achieving HS clinical response after 12 weeks of treatment. A significant reduction in abscesses and inflammatory nodules of 60% (P < 0.004) and 46% (P < 0.001) was seen in anti-TNF naïve and anti-TNF failure groups, respectively. Clinically and statistically significant reduction was seen in patients experiencing pain, with the Visual Analogue Scale pain score reducing by 64% (P < 0.001) and 54% (P < 0.001) in the anti-TNF naïve and anti-TNF failure groups, respectively. IL-1α is emerging as an important clinical target for skin disease, and bermekimab may represent a new therapeutic option for treating moderate-to-severe HS.

ABSTRACT

Objetivo: remover componentes de amalgama de aguas contaminadas mediante fitorremediación. Métodos: se llevó a cabo un estudio descriptivo retrospectivo, en que fueron recolectados 12 litros de aguas de remoción de obturaciones de amalgama en 144 dientes artificiales en la preclínica de odontología. Se analizó agua sin fitorremediar (control), y se mantuvieron ocho litros para fitorremediación en el Laboratorio de Ciencias Básicas y un análisis semanal con dos especies de plantas acuáticas: Eichhornia crassipes y Pistia stratiotes. Mediante espectrofotometría de absorción atómica, se determinó la concentración de metales pesados en miligramos por litro. El análisis se llevó a cabo mediante estadística descriptiva, comparación con prueba t y ANOVA de una vía con el complemento de Excel XLSTAT. Resultados: tras el proceso, el porcentaje estimado de remoción de componentes de amalgama fue superior al 50%. No hubo diferencias estadísticamente significativas entre los tratamientos (α= 0.05; g l= 11; p= 0,4269). Conclusiones: se logró la remoción parcial de componentes de amalgama de aguas contaminadas a través del proceso de fitorremediación.


Objective: remove amalgam components from contaminated water by phytoremediation. Methods: a retrospective descriptive study was carried out, in which 12 liters of amalgam filling removal water were collected in 144 artificial teeth in the preclinical dentistry. Water was analyzed without phytoremediation (control), and eight liters were maintained for phytoremediation in the Laboratory of Basic Sciences and a weekly analysis with two species of aquatic plants: Eichhornia crassipes and Pistia stratiotes. The concentration of heavy metals in milligrams per liter was determined by atomic absorption spectrophotometry. The analysis was carried out using descriptive statistics, comparison with t-test and one-way ANOVA with the Excel XLSTAT add-in. Results: after the process, the estimated removal percentage of amalgam components was greater than 50%. There were no statistically significant differences between treatments (α = 0.05; g l = 11; p = 0.4269). Conclusions: the partial removal of amalgam components from contaminated water was achieved through the phytoremediation process.

ABSTRACT

El tronco arterioso es una anomalía cardiaca relativamente rara, con una incidencia del 0,21-0,34% de los pacientes nacidos con anomalías cardiacas congénitas. Sin reparación quirúrgica precoz, menos del 10% de los pacientes superan el primer año de vida. Presentamos un caso de muerte súbita en una paciente de 32 años con tronco arterioso persistente sin corregir quirúrgicamente, y que había llevado una vida compatible con la normalidad hasta los 28 años. Los principales hallazgos de autopsia son un tronco arterial único, donde desembocan los conos de salida de ambos ventrículos. Las arterias coronarias tienen su origen por encima de la válvula truncal. La arteria descendente anterior está lateralizada hacia la izquierda, mientras que las ramas ventriculares de la coronaria derecha son de un tamaño y longitud superiores a lo normal. La descompensación originada por un episodio de vómitos y diarrea previo a su fallecimiento podría justificar una muerte súbita por taquiarritmia (AU)


Truncus arteriosus is a serious cardiac malformation, accounting for 0.21-0.34% of all congenital heart diseases. Without an early surgical treatment, less than 10% of these patients survive more than one year. We reported a case of sudden death in a 32-year-old female patient with persistent truncus arteriosus without surgical correction, who had lived without noticeable symptoms until she was 28. The main autopsy findings were a single arterial truncus in which both right and left ventricles infundibula flow into. Coronary arteries are originated above the tricuspid truncal valve. Left anterior descending coronary artery was displaced towards the left, whereas ventricular branches of the right coronary artery were larger than normal. he unbalanced state due to an episode of vomiting and diarrhea few days before her death could justify an arrhythmic sudden death (AU)

ABSTRACT

Se realizó un estudio acerca del proceso de preparación y desarrollo del personal de dirección. Se presenta un enfoque donde se determina que éste es diferente al resto de los subsistemas de enseñanza y que el aspecto que caracteriza la enseñanza a dirigentes es la práctica de estos en dirección, con la divisa permanente de aprender haciendo como concepción básica; se plantea además, que este proceso requiere de un enfoque sistémico diferenciado y se señala el estudio de las tendencias actuales de este tipo de capacitación en otros países. Se hace referencia a la necesidad de precisar el carácter cibernético del sistema objeto de estudio (AU)

ABSTRACT

En un periodo de 33 meses (enero de 1984 a octubre de 1986) en el Hospital "Luis Castelazo Ayala" del IMSS., se realizaron 35 operaciones de cistouretropexia retropúbica con el procedimiento de Burch, en pacientes seleccionadas conforme a un protocolo establecido. La patología concomitante más frecuentemente observada, por la cual en un segundo tiempo se indicó la operación de Burch, fue la uterina, siguiéndole en orden decreciente la incontinencia urinaria recidivante, control definitivo de la fertilidad y patología anexial. Se observaron complicaciones transoperatorias en 14.3% de los casos; siendo la de mayor relevancia una lesión vesical. Se obtuvo un porcentaje de curaciones de 83% con seis fracasos, cuatro de los cuales correspondieron a pacientes operadas en los primeros cuatro meses
