Trauma in Pregnancy.

One of the most common causes of obstetric morbidity and mortality is trauma in pregnancy. Several maternal physiological changes during pregnancy have a significant impact on the mechanism, presentation, and management of trauma in this population. It is crucial for health providers dealing with trauma to know and understand these differences between pregnant and nonpregnant patients. The obstetric trauma patient requires a multidisciplinary approach, including obstetrics, maternal fetal medicine, anesthesiology, surgery, and intensive care teams. The aim of this article is to review the most updated information on trauma during pregnancy.

Subphenotypes of severe early-onset pre-eclampsia at hospital admission. A Latin American single-center exploratory latent class analysis.

OBJECTIVES: To identify distinct subphenotypes of severe early-onset pre-eclampsia in Latin America and analyze biomarker and hemodynamic trends between subphenotypes after hospital admission. METHODS: A single-center prospective cohort study was conducted in Colombia. The latent class analysis identified subphenotypes using clinical variables, biomarkers, laboratory tests, and maternal hemodynamics. Class-defining variables were restricted to measurements at and 24 h after admission. Primary and secondary outcomes were severe maternal and perinatal complications. RESULTS: Among 49 patients, two subphenotypes were identified: Subphenotype 1 (34.7%) had a higher likelihood of an sFlt-1/PlGF ratio ≤ 38, maternal age > 35, and low probability of TPR > 1400, CO <8, and IUGR; Subphenotype 2 (65.3%) had a low likelihood of an sFlt-1/PlGF ratio < 38, maternal age > 35, and high probability of TPR > 1400, CO <8, and IUGR. At 24 h postadmission, 64.7% of subphenotype 1 patients changed to subphenotype 2, while 25% of subphenotype 2 patients were reclassified as subphenotype 1. Subphenotype 1 displayed significant changes in CO and TPR, while subphenotype 2 did not. Maternal complications were more prevalent in subphenotype 2, with an odds ratio of 5.3 (95% CI: 1.3-22.0; P = 0.02), but no significant differences in severe neonatal complications were observed. CONCLUSIONS: We identified two distinct subphenotypes in a Latin American cohort of patients with severe early-onset pre-eclampsia. Subphenotype 2, characterized by higher TPR, sFlt-1, and serum creatinine and lower CO and PlGF at admission, was associated with worse maternal outcomes and appeared less modifiable after in-hospital treatment.

Cytotoxic T cells drive doxorubicin-induced cardiac fibrosis and systolic dysfunction.

Doxorubicin, the most prescribed chemotherapeutic drug, causes dose-dependent cardiotoxicity and heart failure. However, our understanding of the immune response elicited by doxorubicin is limited. Here we show that an aberrant CD8+ T cell immune response following doxorubicin-induced cardiac injury drives adverse remodeling and cardiomyopathy. Doxorubicin treatment in non-tumor-bearing mice increased circulating and cardiac IFNγ+CD8+ T cells and activated effector CD8+ T cells in lymphoid tissues. Moreover, doxorubicin promoted cardiac CD8+ T cell infiltration and depletion of CD8+ T cells in doxorubicin-treated mice decreased cardiac fibrosis and improved systolic function. Doxorubicin treatment induced ICAM-1 expression by cardiac fibroblasts resulting in enhanced CD8+ T cell adhesion and transformation, contact-dependent CD8+ degranulation and release of granzyme B. Canine lymphoma patients and human patients with hematopoietic malignancies showed increased circulating CD8+ T cells after doxorubicin treatment. In human cancer patients, T cells expressed IFNγ and CXCR3, and plasma levels of the CXCR3 ligands CXCL9 and CXCL10 correlated with decreased systolic function.

Resective-reconstructive treatment of abnormally invasive placenta: Inter Institutional Collaboration by telemedicine (eHealth).

Introduction: Resective-reconstructive treatment of an abnormally invasive placenta, also known as conservative surgical management, allows a comprehensive treatment of the pathology in only one surgery; however, this alternative is not generally included in international consensus, as it requires specific training. Here, we report our experience of this type of treatment and its plausibility after training facilitated by interinstitutional collaboration via telemedicine.Materials and methods: A total of 48 women who were diagnosed with abnormally invasive placenta, before and after changes due to the resection-reconstruction protocol were included in the study.Results: In total, 14 conservative reconstructive procedures were performed with outcomes of a lower rate of bleeding, reduced transfusions and complications, and a shorter duration of hospitalization than women with hysterectomy.Conclusion: Conservative surgical management is a safe alternative when implemented at specialized centers by trained groups of professionals. Interinstitutional collaboration, using appropriate telemedicine is a safe and effective alternative to enable training in resective-conservative management of abnormally invasive placenta.

[Association between cutaneous leishmaniasis incidence and the human development index and its components in four endemic states of Venezuela]. / Asociación entre la incidencia de leishmaniosis cutánea y el índice de desarrollo humano y sus componentes en cuatro estados endémicos de Venezuela.

OBJECTIVES: Assess potential relationships between the Human Development Index (HDI) and its components and the incidence of cutaneous leishmaniasis (CL) in four endemic States of Venezuela (Mérida, Trujillo, Lara and Sucre) in the period 1994-2003. MATERIAL AND METHODS: Socioeconomical data (classified according the World Bank) was obtained from the National Institute of Statistics, and the epidemiological data from the Ministry of Health, both from Venezuela. For this ecological study the annual variation of the variables was assessed and also regression models were done. RESULTS: The HDI varied in the period from 0.6746 in 1994 to 0.8144 in 2003 (p=0.90). During this time an increase in the cumulative incidence of Leishmaniasis was observed, particularly from 1998 (7.3 cases/100,000 pop) to 1999 (11.3 cases/100,000 pop). Analyzing the linear regression models, it was observed that the relationship between epidemiological and social variables was different at States levels. For Mérida and Trujillo it was observed a significant decrease in the CL regard to the increase of literacy (p<0.05), of the gross combined enrollment (p<0.05), life expectancy (p<0.05), money income (p<0.05) and the HDI (p<0.05). CONCLUSION: This information reflects the significant influence of socioeconomical indicators on the CL incidence at Trujillo and Merida, being an inverse relationship between both types of variables; with an increase or improvement in the socioeconomical indicators, the disease incidence rate decreased.

Asociación entre la incidencia de leishmaniosis cutánea y el índice de desarrollo humano y sus componentes en cuatro estados endémicos de Venezuela / Association between cutaneous leishmaniasis incidence and the human development index and its components in four endemic states of Venezuela

Objetivos. Evaluar las posibles asociaciones entre el índice de desarrollo humano (IDH) y sus componentes, y la incidencia de Leishmaniosis cutánea (LC) en cuatro estados endémicos de Venezuela (Mérida, Trujillo, Lara y Sucre) en el período 1994 al 2003. Materiales y métodos. La data socioeconómica (clasificada de acuerdo al Banco Mundial) se obtuvo del Instituto Nacional de Estadística y la epidemiológica del Ministerio de Salud, ambos de Venezuela. Para este estudio ecológico se evaluó la variación anual de las variables y se realizó modelos de regresión. Resultados. El IDH varió en el período, de 0,6746 en 1994 a 0,8144 en 2003 (p=0,90), asimismo, se observó un aumento de la incidencia acumulada de Leishmaniosis, en especial del año 1998 (7,3 casos/100 000 hab) a 1999 (11,3 casos/100 000 hab). Al analizar con los modelos de regresión lineal, se observó que la relación entre las variables epidemiológicas y sociales era diferente a nivel de los Estados evaluados. Para Mérida y Trujillo se observó un descenso significativo de la incidencia de LC con relación al aumento del porcentaje de alfabetización (p menor que 0,05), de estudiantes matriculados (p menor que 0,05), la esperanza de vida (p menor que 0,05), su ingreso en USD per cápita por año (p menor que 0,05) e IDH (p minor that 0,05). Conclusión. Esta información refleja la influencia significativa de los indicadores socioeconómicos sobre la incidencia de la LC en los Estados Trujillo y Mérida, siendo inversa entre ambos tipos de variables; con el incremento o mejoría de los indicadores socioeconómicos, la incidencia acumulada de la enfermedad disminuyó.

Aspectos sociales de la malaria importada en Latinoamérica / Social Aspects related to imported malaria in Latin America

La malaria continúa siendo un grave problema de salud pública mundial, ya no sólo en países endémicos, sino comenzando a representar un dilema médico en países distantes por la llegada de casos importados. Ahora bien, aun cuando en términos de las disciplinas médicas convencionales se ha publicado muchos estudios clínico-epidemiológicos y reportes de caso, los aspectos sociales, que parecerían obvios en el contexto de la malaria importada por supeditarse a la migración de la población, no han sido exhaustivamente explorados en relación con este fenómeno. Por estas razones, en esta revisión se analiza los aspectos sociales relacionados con el fenómeno de lamalaria importada con énfasis al contexto epidemiológico de América Latina.

Malaria continues to be a world public health problem, not only in those endemic countries but also now beginning to be a medical dilemmain distant countries for the arrival of imported cases. Now, even when in terms of the conventional medical disciplines many clinical andepidemiological studies, as well case reports, have been published, the social aspects, apparently obvious given the fact imported malaria is related to human population migration, have been not furtherly studied in regard to this phenomena. For these reasons in the current review, the social aspects related with the imported malaria phenomena with emphasis in the epidemiological context of Latin Americaare analyzed.
