PROMRIINE (PRe-operatory Magnetic Resonance Imaging is INEffective) Study: A Systematic Review and Meta-analysis of the Impact of Magnetic Resonance Imaging on Surgical Decisions and Clinical Outcomes in Women with Breast Cancer.

BACKGROUND: The purpose of this study was to review and summarize the association between preoperative magnetic resonance imaging (MRI) and surgical outcomes in women with newly diagnosed invasive breast cancer from published randomized controlled trials (RCT). MATERIALS AND METHODS: Two independent researchers conducted a systematic review through a comprehensive search of electronic databases, including PubMed, Medline, Embase, Ovid, Cochrane Library, and Web of Science. If there was disagreement between the two reviewers, a third reviewer assessed the manuscript to determine whether it should be included for data extraction. The quality of the papers was assessed using the risk of bias tool, and the evidence was analyzed using GRADE. Meta-analyses using a fixed-effects model were used to estimate the pooled risk ratio (RR) and 95% confidence interval (CI). RESULTS: Initially, 21 studies were identified, 15 of which were observational comparative studies. A total of five RCTs were included, and they suggested that preoperative MRI significantly reduced the rate of immediate breast-conserving surgery and increased the risk for mastectomy. CONCLUSIONS: From the RCT perspective, preoperative MRI for newly diagnosed invasive breast cancer did not improve surgical outcomes and may increase the risk of mastectomy.

Real-world evidence of neoadjuvant chemotherapy for breast cancer treatment in a Brazilian multicenter cohort: Correlation of pathological complete response with overall survival.

OBJECTIVES: We aimed to evaluate the pCR rate in patients receiving NAC for the treatment of breast cancer (BC) in a multicenter cohort in Brazil. Additionally, we aimed to use RWD to assess the impact of pCR on OS and DFS. METHODS: This was a retrospective, multicenter cohort study that included female patients over 18 years of age who were diagnosed with nonmetastatic breast cancer and received NAC. OS and DFS at five years were estimated by the Kaplan‒Meier method. Additionally, we conducted a multivariate analysis to identify factors that were significantly associated with pCR and OS. RESULTS: From 2011 to 2020, 1891 patients were included in the study, and 421 (22,3%) achieved pCR (ypT0 ypN0). Considering the presence of residual DCIS, pCR was achieved in 467 patients (23,5%). The pCR rate varied between the subtypes: HER-2+ (p = 0,016) and clinical stage IIIA and IIIB (p < 0,001). Among HER-2+ patients, those who received trastuzumab had a significantly higher pCR rate than those who did not receive trastuzumab (p < 0.0001). Similarly, patients with TNBC who received treatment with platinum-based regimens also showed higher pCR rates (p < 0.0001). OS was grouped according to pCR status, and the OS rate was 88,3% in the pCR group and 58.1% in the non-pCR group (p < 0.0001). The five-year DFS was 92.2% in the pCR group and 64.3% in the non-pCR group (p < 0.0001). CONCLUSION: The pCR rate and its prognostic value varied across BC subtypes. In our study, pCR could be used as a surrogate of favorable clinical outcome, as it was associated with higher OS and DFS rates.

Comparison between the rotary (Hyflex EDM®) and manual (k-file) technique for instrumentation of primary molars: a 12-month randomized clinical follow-up study.

OBJECTIVES: Rotational instrumentation is an alternative for the clinical practice of pediatric dentists. However, there are few records in the literature on the clinical and radiographic aspects of treated teeth over time. Compare instrumentation time and filling quality between manual (k-file) and rotary (Hyflex EDM®) files, and clinically and radiographically follow-up the treated teeth for 12 months. Moreover, the characteristics of glass ionomer restorations and their interference in the treatment prognosis over time were evaluated. METHODOLOGY: In total, 40 children with pulp involvement in primary molars received treatment with Hyflex EDM® or manual rotary files, performed by an operator. Clinical and radiographic aspects were observed at different times to determine the effectiveness of each technique. RESULTS: The rotary system reduced instrumentation time when compared to the use of manual files (p≤0.05), but there was no difference in filling quality between the groups (p≥0.05). Moreover, both types of instrumentation were effective for 12 months (p≥0.05), and restoration retention influenced the emergence of periapical lesions (p≤0.05). CONCLUSION: Although rotary files reduce clinical time, the clinical and radiographic aspects of both techniques were similar over 12 months. Moreover, restoration retention has been shown to be related to treatment prognosis.

Paget Disease of the Vulva: Diagnosis by Immunohistochemistry.

The objective of this paper is to report a case of extramammary Paget disease of the vulva, to describe its diagnosis, surgical treatment, and outcome, and to discuss the general characteristics of this pathology. This is a rare neoplasm, found principally in areas in which apocrine and eccrine glands are numerous. This case report is relevant to the literature since the differential diagnosis of extramammary Paget disease is difficult to be done only with the macroscopic appearance of the lesion and even with the microscopic characteristics, requiring further studies, immunohistochemistry, as to differentiate pathologies. The present report describes the case of a 63-year-old patient at the Santa Casa de Misericórdia Hospital in Vitória, Espírito Santo, Brazil, who presented with a hardened, ulcerated, and purplish lesion with hyperchromic and hypochromic spots, measuring 4 cm in diameter, located on the lower third of right labium majus, close to the vaginal fourchette. A right hemivulvectomy was performed, leaving wide margins all around. The patient progressed satisfactorily following surgery. Although extramammary Paget disease is rare, its incidence increases as a function of the patient's age. Patients should be followed up closely because of the risk of persistence and/or recurrence of the disease.

Genital Schistosomiasis: A Report on Two Cases of Ovarian Carcinomas Containing Viable Eggs of Schistosoma mansoni.

Schistosomiasis is a parasitic infection that is highly prevalent worldwide, with a variety of species being responsible for causing the disease. In Brazil, however, the only identified species is Schistosoma mansoni. The adult parasites inhabit the blood vessels of the hepatic portal system of the main host. The disease may range from being asymptomatic to provoking liver damage or portal hypertension. Furthermore, ectopic schistosomiasis may develop, and several hypotheses have been raised to explain the occurrence of the disease. This paper describes two cases, one in a 39-year-old woman and the other in a 47-year-old woman. Both had similar symptoms of pain and abdominal distension caused by a large abdominal/pelvic mass. Histopathology of the ovary showed a mucinous cystadenocarcinoma of the intestinal type in the first patient and a papillary serous carcinoma in the second, with both tumors containing viable eggs of Schistosoma mansoni. The neoplasms probably serve as a migratory route for the adult parasites and the embolization of eggs. Nevertheless, there is insufficient evidence to confirm the malignization of a benign lesion due to the presence of Schistosoma mansoni. Few cases have been reported in the international literature on the association between ovarian schistosomiasis and neoplasms.

Insuficiência cardíaca e depressão: uma associação com desfechos negativos / Depression and heart failure: an association with negative outcomes / Insuficiencia cardíaca y depresión: una asociación con resultados negativos

Este trabalho trata da relação entre depressão e doença cardiovascular (DCV), a qual tem relevância na piora clínica de pacientes portadores de insuficiência cardíaca (IC), bem como no aumento da taxa de hospitalizações e morbimortalidade. A depressão é mais prevalente em pacientes com IC que na população em geral, devido a hipóteses sobre o aumento da estimulação neuro-hormonal e das citocinas, mesmo em presença de menor comprometimento cardíaco. Os desfechos clínicos negativos oriundos desta associação levam ao ônus público e social. Esta revisão abordará os mecanismos psicossociais e fisiopatológicos determinantes desta associação, bem como o tratamento, o diagnóstico e prevenção da depressão em pacientes com insuficiência cardíaca. Espera-se suscitar reflexões sobre o cuidado clínico dos portadores de IC, considerando seus estressores psicossociais de adaptação para melhor monitoramento, logo, detecção precoce desta associação.

This paper deals with the relationship between depression and cardiovascular disease, which has relevance to clinical worsening in patients with heart failure (HF), as well as increased rate of hospitalizations and mortality. Depression is more prevalent in patients with HF in the general population, due to assumptions about the increased neurohormonal stimulation and cytokines, even in the presence of minor cardiac involvement. Outcomes from this negative association lead to public and social burden. This review will discuss the pathophysiological mechanisms and psychosocial determinants of this association, as well as treatment, diagnosis and prevention of depression in patients with heart failure. Expected to generate reflections on the clinical care of patients with HF, considering its adaptation to psychosocial stressors better monitoring, so early detection of this association.

El presente trabajo trata sobre la relación entre depresión y enfermedad cardiovascular, la cual tiene relevancia en el empeoramiento clínico de pacientes con insuficiencia cardíaca, así como en el aumento de la tasa de hospitalización y mortalidad. La depresión tiene mayor prevalencia en pacientes con insuficiencia cardíaca que en la población general, debido a las diversas hipótesis sobre el aumento de la estimulación neurohormonal y de las citoquinas, incluso en presencia de compromiso cardíaco menor. Los resultados clínicos de esta asociación negativa suponen una carga pública y social. En esta revisión se abordarán los mecanismos psicosociales y los determinantes fisiopatológicos de esta asociación, así como el diagnóstico, tratamiento y prevención de la depresión en pacientes con insuficiencia cardíaca. Se espera generar algunas reflexiones sobre la atención clínica de los pacientes portadores de insuficiencia cardíaca, considerando los factores de estrés psicosociales de adaptación para un mejor seguimiento, y por ende, la detección precoz de esta asociación.
