13. Broadband Antennas Based on the Double Moebius Strip
Abstract The family of new antenna designs based on the double Moebius strip principle is proposed in this article. Three possible options of the power supply port location had been reviewed in this respect: the cut external strip with the signal port located directly in the cut area is used; the continuous rings without discontinuities are applied, with the

14. Renal volume of five-year-old preterm children are not different than full-term controls
Abstract Objective: In previous studies, smaller renal volumes were reported in prematurely born infants, however, these renal volumes were not corrected for body surface area, the main determinant of renal size. Given the rapid growth of the renal cortex after premature birth, the authors hypothesized that corrected volumes would not differ from healthy co

15. A Clinical Risk Analysis of Postoperative Nausea and Vomiting After Colorectal Cancer Surgery
Abstract Objective Postoperative nausea and vomiting (PONV) is a frequent complication following colorectal surgery. The present study investigated the risk factors for PONV after colorectal cancer surgery. Methods A retrospective study of 204 patients who underwent surgery for colorectal cancer was conducted. Univariate and multivariate analyses were perf

16. Higher Symptom Score, Larger Residual Rectocele, and Lower Rectal Compliance Predict Failure of Improvement after Surgical Treatment of Rectocele
Abstract Background Rectocele is a frequent finding in women and is usually asymptomatic. However, it is sometimes associated with symptoms of obstructed defecation syndrome (ODS). While most patients with ODS due to rectocele respond well to conservative treatment, some may require surgical treatment. The aim of the study was to determine the predictors of

17. Braden scale for predicting pneumonia after spontaneous intracerebral hemorrhage
SUMMARY OBJECTIVE: Stroke-associated pneumonia is an infection that commonly occurs in patients with spontaneous intracerebral hemorrhage and causes serious burdens. In this study, we evaluated the validity of the Braden scale for predicting stroke-associated pneumonia after spontaneous intracerebral hemorrhage. METHODS: Patients with spontaneous intracere

18. Highlights of clinical and laboratory parameters among severe COVID-19 patients treated with tocilizumab: a retrospective observational study
ABSTRACT BACKGROUND: Coronavirus disease 2019 (COVID-19) can cause cytokine release syndrome (CRS), which leads to high mortality rates. Tocilizumab suppresses CRS by blocking the signal transduction of interleukin-6 (IL-6). OBJECTIVE: To evaluate the clinical and laboratory parameters associated with mortality among patients receiving tocilizumab treatmen

19. Cardiac Surgery-associated Acute Kidney Injury in Patients with Preserved Baseline Renal Function
ABSTRACT Introduction: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a powerful predictor of perioperative outcomes. We evaluated the burden of CSA-AKI in patients with preserved baseline renal function. Methods: The data of 2,162 adult patients who underwent cardiac surgery from January 2005 to December 2020 were analyzed. Logistic regressio

21. Analysis of the related risk factors of inguinal lymph node metastasis in patients with penile cancer: A cross-sectional study
ABSTRACT Purpose: To determine independent predictors of inguinal lymph node (ILN) metastasis in patients with penile cancer. Patients and methods: We retrospectively analyzed all patients with penile cancer who underwent surgery at our medical center in the last ten years (n=157). Using univariate and multivariate logistic-regression models, we assessed a

22. Wnt3a but not CDX-2 expression is associated with differentiated thyroid cancer
SUMMARY OBJECTIVE: Thyroid neoplasm incidence has increased worldwide, mostly due to the advancements in medical imaging and screening rates. The aberrant Wnt/β-catenin pathway has been identified as a key mechanism, and it has also been related to the metastatic activity of differentiated thyroid cancer. We aimed to verify the difference in the expression

23. Is Frailty Syndrome a Predictor of Morbimortality in Postoperative Cardiac Surgery? – A Retrospective Cohort Study
Abstract Background Frailty is a biological syndrome suggested as a better predictor of morbimortality than chronological age. Objective To assess associations between frailty and morbimortality outcomes in postoperative cardiac surgery. Methods A retrospective cohort study was conducted with cardiac surgery patients. Frailty and maximal inspiratory pr

24. Thirty-day Outcomes of On-Pump and Off-Pump Coronary Artery Bypass Grafting: an Analysis of a Brazilian Sample by Propensity Score Matching
Abstract Introduction: Coronary artery bypass grafting (CABG) performed with and without cardiopulmonary bypass (CPB) support has been widely discussed in the literature. However, little is known about the outcomes of those techniques in Brazil. This study aims at exploring 30-day mortality and morbidity outcomes of on- and off-pump isolated CABG in a large
