Neoadjuvant Chemotherapy plus Interval Cytoreductive Surgery with or without Hyperthermic Intraperitoneal Chemotherapy (NIHIPEC) in the Treatment of Advanced Ovarian Cancer: A Multicentric Propensity Score Study.

INTRODUCTION: Epithelial ovarian cancer (EOC) is primarily confined to the peritoneal cavity. When primary complete surgery is not possible, neoadjuvant chemotherapy (NACT) is provided; however, the peritoneum-plasma barrier hinders the drug effect. The intraperitoneal administration of chemotherapy could eliminate residual microscopic peritoneal tumor cells and increase this effect by hyperthermia. Intraperitoneal hyperthermic chemotherapy (HIPEC) after interval cytoreductive surgery could improve outcomes in terms of disease-free survival (DFS) and overall survival (OS). MATERIALS AND METHODS: A multicenter, retrospective observational study of advanced EOC patients who underwent interval cytoreductive surgery alone (CRSnoH) or interval cytoreductive surgery plus HIPEC (CRSH) was carried out in Spain between 07/2012 and 12/2021. A total of 515 patients were selected. Progression-free survival (PFS) and OS analyses were performed. The series of patients who underwent CRSH or CRSnoH was balanced regarding the risk factors using a statistical analysis technique called propensity score matching. RESULTS: A total of 170 patients were included in each subgroup. The complete surgery rate was similar in both groups (79.4% vs. 84.7%). The median PFS times were 16 and 13 months in the CRSH and CRSnoH groups, respectively (Hazard ratio (HR) 0.74; 95% CI, 0.58-0.94; p = 0.031). The median OS times were 56 and 50 months in the CRSH and CRSnoH groups, respectively (HR, 0.88; 95% CI, 0.64-1.20; p = 0.44). There was no increase in complications in the CRSH group. CONCLUSION: The addition of HIPEC after interval cytoreductive surgery is safe and increases DFS in advanced EOC patients.

Resistencia de la población hacia la vacunación en época de epidemias: a propósito de la COVID-19 / Public Resistance to Vaccination During Epidemics: The Example of COVID-19 / Resistência da população à vacinação em tempos de epidemias: sobre a COVID-19

RESUMEN Objetivo. El presente artículo busca exponer los hallazgos de una revisión de la literatura sobre la resistencia de la población frente a las vacunas y las principales razones que han influido en sus decisiones hacia a la inmunoprevención, con foco en la pandemia de la COVID-19. Métodos. Se realizó una búsqueda en la literatura utilizando los términos DeCs/MeSH, Anti-Vaccination Movement, Vaccination refusal, Epidemics, COVID-19, Impacts on health, relacionados entre ellos por los operadores booleanos OR y AND en Google Scholar, Medline, Lilacs e Ibecs; también se tuvieron en cuenta documentos de fuentes oficiales. Resultados. A lo largo de la historia, desde el inicio de la vacunación, la percepción de las personas hacia este procedimiento ha sido controversial, hay quienes aceptan lo que las autoridades sanitarias recomiendan y quienes alegan intenciones ocultas detrás de la inmunización; la vacuna contra el SARS-CoV-2 causante de la COVID-19 no ha sido la excepción. Conclusiones. La vacunación ha sido uno de los mayores logros científicos en términos de salud pública, un avance que, a pesar de sus beneficios, ha causado miedo, incertidumbre y suspicacias en la población. Por esta razón, resulta importante incrementar las acciones de educación para la salud en la población, con información clara, concisa y comprensible, y sustentada en fuentes confiables y verídicas, con el fin de disminuir la resistencia a la vacunación y evitar las enfermedades prevenibles.

ABSTRACT Objective. This article presents the findings of a review of the literature on public resistance to vaccines and the main factors that have influenced their decisions about immunoprevention, with a focus on the COVID-19 pandemic. Methods. We searched the literature using the terms DeCs/MeSH, anti-vaccination movement, vaccination refusal, epidemics, COVID-19, and impacts on health, using the Boolean operators OR and AND in Google Scholar, Medline, Lilacs, and Ibecs. Documents from official sources were also considered. Results. Throughout history, since vaccination began, people have had controversial perceptions of the procedure: some accept what the health authorities recommend, and others allege hidden intentions behind immunization. The COVID-19 vaccine against SARS-CoV-2 has been no exception. Conclusions. Vaccination has been one of the greatest scientific achievements in public health. However, despite its benefits, it has raised fear, uncertainty, and suspicion in the population. For this reason, it is important to increase health education actions in the population—with clear, concise, understandable information that is based on reliable and truthful sources—in order to reduce resistance to vaccination and address preventable diseases.

RESUMO Objetivo. Este artigo busca apresentar os achados de uma revisão da literatura sobre a resistência da população às vacinas e os principais motivos que influenciaram suas decisões em relação à imunoprevenção, com foco na pandemia de COVID-19. Métodos.

Documentos de fontes oficiais também foram levados em consideração. Resultados. Ao longo da história, desde o início da vacinação, a percepção das pessoas em relação a esse procedimento foi controversa. Há quem aceite o que as autoridades de saúde recomendam e quem alegue intenções ocultas por trás da imunização. A vacina contra o SARS-CoV-2, que causa a COVID-19, não foi exceção. Conclusões. A vacinação tem sido uma das maiores conquistas científicas em termos de saúde pública - um avanço que, apesar de seus benefícios, tem causado medo, incerteza e desconfiança na população. Por isso, é importante aumentar as ações de educação em saúde para a população, com informações claras, concisas e compreensíveis, baseadas em fontes confiáveis e verídicas, a fim de diminuir a resistência à vacinação e evitar doenças preveníveis.

Primary malignant teratoma of lung: report of a case and review of the literature.

We describe a rare case of malignant teratoma involving the entire right lung. A 28 years old man was admitted to the hospital with severe respiratory failure and general malaise. Chest X-ray showed a dense opacity of the entire right lung, accompanied by pleural effusion. At autopsy, the right lung was completed replaced by a mass of variegated appearance combining cystic spaces and solid areas. Microscopically, the lung tumor exhibited a polymorphous histological picture. Most of the tissue had a malignant mesenchymal appearance, which included areas of chondrosarcoma, chondroblastic osteosarcoma, well differentiated liposarcoma, and undifferentiated pleomorphic sarcoma. Other areas of the tumor showed malignant epithelial components consistent with bronchial and urothelial mucosa with also scattered islands of pigmented epithelium of probable neuronal or retinal nature.
