Introduction: At the beginning of the COVID-19 pandemic, a drop in the number of patients treated for cardiac emergencies raised concern about cardiovascular mortality in that period. An increase in care delay for patients with ST-segment elevation myocardial infarction (STEMI) may have affected clinical outcomes. Objectives: To analyze delay times and clinical outcomes of patients with STEMI undergoing primary percutaneous coronary intervention (PPCI), before and during the COVID-19 pandemic. Methods: Retrospective observational study that included patients with STEMI undergoing PPCI from December 2018 to July 2021. The COVID-19 pandemic cases were divided into two groups: pandemic I—from March to August 2020;and pandemic II—from September 2020 to July 2021. Patients were compared according to the period of hospitalization. Primary outcomes were delay times in assistance and clinical outcomes (acute kidney injury [AKI], post-procedural vascular complications and in-hospital mortality). Results: 108 patients were included, 39 (36.1%) in the pre-pandemic period, 13 (12.1%) in pandemic I and 56 (51.8%) in pandemic II. Time from onset of symptoms to arrival at the service and door-to-balloon time did not differ significantly among groups. Vascular complications were more frequent during the pandemic (I and II) than in the pre-pandemic period (2.5% pre-pandemic vs 15.4% pandemic vs 12.5% pandemic II;p = 0.03). AKI incidence was similar in all three periods. There was a non-significant increase in in-hospital mortality during the COVID-19 pandemic. Conclusion: In patients with STEMI, there was an increase in vascular complications and a trend toward increased mortality during the COVID-19 pandemic. Delay times to admission and reperfusion did not differ significantly between before and during the pandemic.

Successful double fertilization and subsequent seed development in flowering plants requires the delivery of two sperm cells, transported by a pollen tube, into the embryo sac of an ovule. The embryo sac cells tightly control synergid cell death, and as a result the polyspermy block. Arabinogalactan proteins are highly glycosylated proteins thought to be involved in several steps of the reproductive process. We show that JAGGER, Arabinogalactan Protein 4, is an important molecule necessary to prevent the growth of multiple pollen tubes into one embryo sac in Arabidopsis thaliana. In jagger, an AGP4 knockout mutant, the pistils show impaired pollen tube blockage as a consequence of the survival of the persistent synergid. JAGGER seems to be involved in the signaling pathway that leads to a blockage of pollen tube attraction. Our results shed light on the mechanism responsible for preventing polyspermy in Arabidopsis and for safe- guarding successful fertilization of all ovules in one pistil, ensuring seed set and the next generation.

Background: Recently, late umbilical cord clamping is generally recommended, which decreases neonatal anemia;however, it may also increase neonatal jaundice and some other poor outcomes. Objectives: We here attempted to determine whether late clamping actually increases the incidence of phototherapy for jaundice and other poor outcomes of the term “low-risk newborns”. Methods: With the approval of the Brazilian Registry of Clinical Trials (REBEC), a total of 357 low-risk newborns (singleton, uncomplicated pregnancy/delivery, in a Brazilian public institution) were randomized into two groups: group I (n = 114): cord clamping 1 minute (early clamping) or group II (n = 243): cord clamping between 1 - 3 minutes (late clamping). Statistics were used appropriately (i.e., measures of central tendency, dispersion for continuous variables, Shapiro-Wilk, Mann-Whitney test, or Chi-square test). Results: Phototherapy was performed in 5.3% in both groups. Also, there were no statistical differences in the occurrence of secondary outcomes, such as sepsis, neonatal ICU admission, and transient tachypnea of the newborns: i.e., 0.9%, 15.8%, and 3.5%, respectively for group I versus 1.2%, 15.6%, and 5.8%, respectively for group II. Conclusion: Late umbilical cord clamping does not increase the need for phototherapy in low-risk neonates. This result corroborates the current recommendation of late cord clamping, whenever appropriate.

Background: IgG4-related disease is a rare autoimmune condition that presents with lymphoplasmacytic infiltrate and fibrosis in the organ affected. Isolated testicle involvement is uncommon and there are only a few cases reported in the literature. Case Presentation: We report a case of isolated chronic orchitis due to IgG4 hypersecretion in a 61-year-old patient that evolved with asymptomatic tumor-like mass growth and was treated with left orchiectomy. Histopathological study revealed orchitis related to IgG4 hypersecretion disease. Conclusion: IgG4-related disease can be manifested as a multi or single-organ disorder. Most diagnoses are made after surgery with histopathological analysis. Most of the cases in literature stand out the difficulty in diagnosis and necessity of high suspicion due to this condition’s similarity with neoplasm presentation.
