    Abstract Objective:  Our objective was to evaluate the association between severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) serologic status in immunologically naive patients and the risk of preeclampsia at the time of delivery.
    Study design:  We conducted a retrospective cohort study of pregnant patients admitted to our institution from August 1 to September 30, 2020. We recorded maternal medical and obstetric characteristics and SARS-CoV-2 serologic status. Our primary outcome was the incidence of preeclampsia. Antibody testing was performed, and patients were classified into seropositive groups: immunoglobulin (Ig)G + , IgM + , or both IgG+ and IgM + . Bivariate and multivariable analyses were performed.
    Results:  We included 275 patients that were negative for SARS-CoV-2 antibodies, and 165 that were positive. Seropositivity was not associated with higher rates of preeclampsia (
    Conclusion:  We found that in an obstetric population, there was no association between SARS-CoV-2 antibody status and the risk of preeclampsia.
    Key points: · Pregnant people with acute COVID-19 are at an increased risk of developing preeclampsia.. · Seroconversion during pregnancy was not associated with an increased risk of preeclampsia.. · Further study regarding the timing of infection and its association with preeclampsia is necessary..

    Abstract Based on the pathophysiological characterization of COVID-19, initial studies suggested the use of tocilizumab (TCZ), a recombinant humanized monoclonal antibody of the immunoglobulin G1 class, for management of the cytokine storm witnessed in severe cases. Thus, we decided to present a case series of 18 patients with severe COVID-19 treated with TCZ at our hospital. Our results coincide with the fact that the routine use of TCZ in severe COVID-19 is not robustly supported. We believe that the efficacy and safety of this drug and other related molecules should be validated in large randomized clinical trials.

    Title translation Acute cardiovascular complications in a Peruvian population of oncology patients.
    Abstract Objective: To know the most frequent acute cardiovascular complications in a Peruvian population of oncologic patients.
    Materials and methods: Retrospective, descriptive study of oncologic patients treated at Clinica Delgado between January 2014 and December 2019, from which the subgroup with the seven most prevalent cancers at the national level was selected according to information from Globocan 2018. Additionally, we evaluated the epidemiology of patients with cardiovascular complications that conditioned their hospitalization or were detected during this, calculating their cardiovascular risk according to Hermann and SCORE risk scales.
    Results: Forty-four patients had complications; 27 (61.4%) were hospitalized due to acute cardiovascular causes. The mean age of this subgroup was 69.88 years (SD 12.77), and 22 (81.5%) were older than 60 years. Fourteen (51.9%) were male. According to the Hermann scale, 33.3% had intermediate-risk and 14.9% had a high or very high risk. According to the SCORE scale, 62.97% had an intermediate-risk and 7.40% high risk. The most common acute cardiovascular complications were deep vein thrombosis and ischemic stroke (66.65%). One patient (3.7%) reported previous cardiovascular disease. Four patients (14.8%) had a fatal outcome during hospitalization. The median length of hospitalization was five days.
    Conclusions: We present the cases of acute cardiovascular complications in a population of oncologic patients and their vascular risk according to Hermann and SCORE scales. The most common complications were deep vein thrombosis (48.14%), stroke (18.51%), and myocardial infarction (14.81%).

    Abstract Introduction: Dedifferentiated chondrosarcoma (DDC) is an aggressive osseous neoplasm with a dismal prognosis. Treatment commonly involves limb-salvage surgery or amputation. In patients with appendicular DDC, we sought to describe demographic, clinical and treatment characteristics (1), analyze risk factors for metastasis (2) and overall death (3), and assess survival rates by treatment (4).
    Materials and methods: Two-hundred-and-five patients from the SEER Database were included in our analysis. Demographic, clinical and treatment variables were analyzed. Multivariate regression was performed to identify risk factors. Survival analysis was performed using the Kaplan-Meier method.
    Results: Fifty-one (24.9 %) of the patients included presented metastasis at diagnosis. The most common locations were the lungs, other sites, and bone. Surgery to the primary site was more common in patients without metastasis (94.2 %) than those with (78.2 %); limb-salvage procedures were more common than amputations. Tumors >8 cm (T2) and those discontinuous (T3) were more likely to present metastasis at diagnosis (OR = 2.54, p = 0.043 and OR = 7.4, p = 0.008, respectively). Female gender was found to be a protective factor for overall death on crude analysis (OR = 0.33, p = 0.019). Metastases to sites other than the lungs (M1b) had the highest risk of overall death (OR = 49, p = 0.01). Combination of surgery and chemotherapy showed a trend towards higher overall survival in non-metastatic patients (p = 0.1069 and p = 0.1703).
    Conclusions: Appendicular DDC displays a high metastatic rate and low survival rates. The most common procedure is a limb-salvage surgery. Tumor size increases the risk of presenting metastases at diagnosis and female gender is a protective factor against death.

    Abstract Introduction: Merkel cell carcinoma (MCC) is an aggressive cutaneous cancer that frequently compromises the lymph nodes (LN) and distal organs. We sought to describe clinical and demographic characteristics of affected patients, analyze risk factors for LN compromise, metastasis, and death, and evaluate their impact on survival.
    Materials and methods: Patients with MCC were retrieved from the SEER database. Demographic, clinical and treatment data were analyzed. Logistic and Cox proportional hazard regression were used to analyze risk factors. Survival analysis was done with the Kaplan-Meier method.
    Results: A total of 2010 patients were included, among which 288 (14.33%) had distant metastases at diagnosis. LN involvement occurred in 45.8% and 20.1% of patients with and without distant metastasis, respectively. Males were more likely to present LN compromise (OR = 1.33, p<0.001). Tumors >10 mm showed a significantly higher risk for LN involvement and distant metastasis, with those >20 mm showing the highest risk (OR = 2.76 p<0.001 and OR = 8.88 p<0.001 respectively). Location of the tumor in the trunk was a protective factor for overall death (OR = 0.27), while LN compromise was a risk factor (OR = 3.12). Only history of previous malignancy significantly affected disease-specific death (OR = 0.32, p = 0.01). One-year survival was 79.7% and 38.2% for patients with regional LN disease and distant metastasis, respectively.
    Conclusion: MCC is an aggressive cancer with high rates of LN involvement and distant metastases. Male gender and tumor size were risk factors for regional LN and metastatic disease. Tumor location in the trunk decrease the risk of overall death, while LN involvement increased it.
