OBJECTIVE
Patients with ankylosing spinal disorders (ASDs), such as ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis, often have rigid kyphosis of the spine. The fracture site is sometimes unintentionally displaced when surgery is conducted with the patient prone. To prevent this incident, the authors adopted the lateral decubitus position for patients intraoperatively for this pathology. The aim of this study was to retrospectively assess the impact of the lateral decubitus position in the perioperative period on posterior fixation for thoracolumbar fractures with ASD.

METHODS
Thirty-seven consecutive patients who underwent posterior instrumentation for thoracolumbar fracture with ASD at the authors’ institute were divided into 15 lateral decubitus positions (group L) and 22 prone positions (group P). Surgical time, estimated blood loss (EBL), number of levels fused, perioperative complications, length of stay (LOS), ratio of fracture voids, and ratio of anterior wall height were investigated. The ratio of fracture void and the ratio of anterior wall height were the radiological assessments showing a degree of reduction in vertebral fracture on CT.

RESULTS
Age, sex, BMI, fracture level, and LOS were similar between the groups. Levels fused and EBL were significantly shorter and less in group L (p < 0.001 and p = 0.04), but there was no significant difference in surgical time. The complication rate was similar, but 1 death within 90 days after surgery was found in group P. The ratio of fracture voids was 85.4% ± 12.8% for group L and 117.5% ± 37.3% for group P. A significantly larger number of patients with a fracture void ratio of 100% or less was found in group L (86.7% vs 36.4%, p = 0.002). The ratio of anterior wall height was 107.5% ± 12.3% for group L and 116.9% ± 18.8% for group P. A significantly larger number of patients with the anterior wall height ratio of 100% or less was also found in group L (60.0% vs 27.3%, p = 0.046).

CONCLUSIONS
The results of this study suggest that the lateral decubitus position can be expected to have an effect on closing or maintaining the fracture void or a preventive effect of intraoperative unintentional extension displacement of the fractured site, which is often seen in the prone position during surgery for thoracolumbar fractures involving ASD.

OBJECTIVE
Guidelines recommend antimicrobial prophylaxis (AMP) preoperatively for "clean" spinal and cranial surgeries, while dose and timing remain controversial. The use of multiple-dose AMP for such surgeries is under debate in the pediatric context. In this clinical study, the authors aimed to compare single-dose with multiple-dose prophylactic antibiotic usage in cranial and spinal neurosurgical interventions of pediatric patients.

METHODS
All neurosurgical patients aged 28 days to 18 years who underwent surgery at a single tertiary center were assessed. Three cohorts (noninstrumented clean spinal, noninstrumented cranial, and instrumented cranial interventions), each of which comprised two 50-patient arms (i.e., single-dose AMP and multiple-dose AMP), were included after propensity score–matched retrospective sampling and power analysis. Records were examined for surgical site infections. Using a previously published meta-analysis as the prior and 80% acceptance of equivalence (margin of OR 0.88–1.13), logistic regression was carried out for the total cohort and each subcohort and adjusted for etiology by consideration of multiple-dose AMP as reference.

RESULTS
The overall sample included 300 age- and sex-matched patients who were evenly distributed in 3 bi-arm cohorts. There was no statistical intercohort difference based on etiology or type of operation (p < 0.05). Equivalence analysis revealed nondiscriminating results for the total cohort (adjusted OR 0.65, 95% CI 0.27–1.57) and each of the subcohorts (noninstrumented clean spinal, adjusted OR 0.65, 95% CI 0.12–3.44; noninstrumented cranial, adjusted OR 0.52, 95% CI 0.14–2.73; and instrumented cranial, adjusted OR 0.68, 95% CI 0.13–3.31).

CONCLUSIONS
No significant benefit for multiple-dose compared with single-dose AMPs in any of the pediatric neurosurgery settings could be detected. Since unnecessary antibiotic use should be avoided as much as possible, it seems that usage of single-dose AMP is indicated.

BACKGROUND: Metaplastic breast carcinoma (MBC) is a rare type of breast cancer (0.20–1.00% of all cases). With a more aggressive clinical course, MBC frequently presents as a triple-negative subtype. OBJECTIVE: To describe a case series, analyzing patients survival in four MBC cases. METHODS: The cases were obtained from 532 medical records of breast cancer patients (0.7% of the total). RESULTS: All patients were female. Mean patient age was 49 years (range: 38–60 years). Mean tumor size was 8.9 cm (range: 3.0–15.5 cm). Mastectomy was performed in three cases. One patient had axillary nodal metastasis. All underwent chemotherapy and three received radiation therapy after surgery. CONCLUSIONS: With a mean follow-up of 36 months (range: 10–60 months), one case had a tumor recurrence (25%). Three patients (75%) died from metastatic disease and one (25%) is still alive and free of disease.

Published: December 2021

BACKGROUND: Bone cements aid in bone regeneration; however, if the handling time is not well established for the material to harden, complications may arise. OBJECTIVE: This work investigates the effect of using polyethylene glycol (PEG) and characterize it in brushite bone cement in order to obtain desirable handling times as well as its regeneration in vivo to analyse if addition of this polymer may significantly modify its properties. METHODS: PEG 4000 was synthesised with wollastonite by phosphorization reaction in order to form brushite which was further cured by oven drying. They were further characterised and tested in vivo as tibial bone defect model using rabbits. RESULTS: Addition of PEG exhibited handling times of 60 min with a low increase in temperature when curing. Brushite phase of ∼71% was obtained after cement hardening with good compressive strength (25 MPa) and decent values of porosity (33%). In vivo presented that, at 40 days postoperatively, accelerated bone neoformation with partial consolidation at 30 days and total after 60 days when using bone cement. CONCLUSIONS: Addition of PEG does not disrupt the beneficial properties of the bone cement and can be a potential alternative to control the time-temperature profile of hardening these materials.

Published: December 2021

This paper contains the results of fire resistance calculation of reinforced concrete columns with advanced calculation methods.
For columns that are tested unloaded, determine the cross-sectional temperature distribution and values of temperature in reinforcement. The fire resistance of columns that have been tested without load is determined according to temperature measurements, with calculation methods according to the requirements of DBN B.1.1-7 andDBN B.1.2-7.
According to the tabulated method, the fire resistance of reinforced concrete columns is determined by geometric parameters such as cross-section width, axis distance of the reinforcement, amount of reinforcement, length or height of the element, load level during the fire exposure, heating conditions during the fire exposure (number of fire exposed sides).
Accidental combination of actions during the fire situation consists of characteristic values of permanent and variable long-term actions taking into account the safety factor for the consequence class of the object (CC2) and the type of design situation (accidental).
Thermal analysis of the column was performed under conditions of the standard fire exposure. In such conditions it was assumed that the column is exposed to fire with four sides for 120 minutes that corresponds to the required fire resistance class R120.
The thermal state of the column was determined using transient thermal models that take into account radiation-convective heat transfer in the ambient from the heat source to the structural surface, convective heat transfer in the structure, radiation-convective heat exchange from the structure to the ambient environment.
The residual load-bearing capacity of the reinforced concrete column after the fire exposure was calculated with the reduced cross-section determined using zone method in accordance with the requirements of DSTU-N B B.2.6-197 and DSTU-N B EN 1992-1-2.
The fire resistance period of columns for the load-bearing criterion was determined on the basis of the results of of thermal and static analysis.

Palavras lusófonas na Comparative Political Theory | Lusophone words in Comparative Political Theory
Authors: Favarato Claudia 
Published: December 2021

The discipline of comparative political theory (CPT) rose within the Anglo-Saxon context in the 1990s; rejecting the existing epistemological hegemony, it aims to integrate non-western theories and thought in political theory. Following a brief overview of CPT, this paper intends to report that CPT in nigh existent in the scholarship of political theory available in Portuguese. The overall scarcity of CPT in Portuguese scholarship texts epitomizes not only the lack of response to comprehensive, globalized or cosmopolitan canons of political theory, as referred in anglophone literature, but also a failure in providing space and representation for authors, texts, ideas and concepts beyond the canons. Among the areas of interests of CPT, political theorizations endogenous of Africa are the least considered ones. In the Portuguese literature of political theory, sub-Saharan and Luso-African political thought and theory are underrepresented.
