title: ANTEGRADE NAILING VERSUS LOCKING PLATE OF 2-AND 3-PART PROXIMAL HUMERUS FRACTURES

description: ABSTRACT Objective: To evaluate and compare the proportions of complications and radiographic findings of osteosynthesis of 2- and 3-part proximal humerus fractures with two methods of treatment: third-generation antegrade nailing and locking plate. Methods: 46 patients with a mean age of 58.9 ± 16.6 years between January 2020 and January 2021 were evaluated. In sixteen cases (34.8%), antegrade nailing was used, and in thirty cases (65, 2%), a locking proximal humerus plate. The method used included the rate of complications with a minimum follow-up of 6 months after surgery and radiographic evaluation. Results: There was no difference between the groups regarding the proportion of complications (nail group 18.8%, plate group 13.3%; p = 0.681). The nail group had less residual varus loss (cervicodiaphyseal angle nail group with 132.1º ± 2.3º, plate group 123.8º ± 10.1º; p &lt; 0.001). In the plate group, women had the lowest value (1.43 ± 0.22) of the deltoid tuberosity index (DTI) compared to men (1.58 ± 0.11) (p = 0.022). Conclusion: Osteosynthesis, with a locking plate and antegrade nailing, did not show differences in the proportion of complications. The nail group had less change in the postoperative cervicodiaphyseal angle, however, there were two serious complications with screw cut-out and varus deviation, requiring surgical reapproach. Level of Evidence II, Retrospective Observational Study.

title: THERMAL IMAGING FOR STRESS ASSESSMENT IN RICE CULTIVATION DRIP-IRRIGATED WITH SALINE WATER

description: ABSTRACT Lowland rice is traditionally irrigated by flood systems, demanding high water consumption. Localized irrigation by subsurface dripping is proposed as an alternative, in addition to the replacement of the source of water intended for human consumption with another of lower quality, such as saline water. However, plants can be affected by saline and/or water stress in both conditions, and the use of thermal imaging emerges as a tool to assess the plant status. In this context, this study aimed to identify the stress of subsurface drip-irrigated arborio rice under different salt concentrations and soil moisture by thermographic images. The design consisted of randomized blocks in a (2×4)+2 factorial with three replications, totaling 30 experimental plots. Soil solution salinity was assessed by electrical conductivity. The thermal images were processed by an algorithm to determine the normalized relative canopy temperature (NRCT) index at different crop development stages. Saline stress was identified by the NRCT index, with higher sensitivity of plants at the flowering stage with a rebalance over time, confirmed at grain filling and harvest stages.

title: STERNUM TOMOGRAPHIC EVALUATION IN PECTUS PATIENTS: ANALYSIS OF SAGITAL PARAMETERS

description: ABSTRACT Objective: To evaluate the sagittal tomographic reformatting of the sternum using unpublished radiographic parameters (indexes and angles), comparing them between the different types of pectus, and controls. Methods: 44 patients with pectus deformities and controls underwent chest CT for analysis. The types of pectus were classified into: inferior pectus carinatum (IPC), superior (SPC) and lateral (LPC), and broad (BPE) and localized pectus excavatum (LPE). The following tomographic parameters were created and measured: (1) spine-manubrium-sternum index (SMS); (2) column-sternum index (CSI); (3) manubrium-sternal angle (MSA); (4) inferior manubrium angle (IMA); and (5) inferior sternum angle (ISA). Statistical analysis was performed between the pectus and control groups, and between the different types of pectus. Results: There was a significant difference between: a) pectus excavatum and pectus carinatum when analyzing the SMS, CSI, MSA and ISA indexes. b) LPE and control group for SMS and ISA. c) LPC and LPE, and LPC and BPE for SMS; d) BPE and LPC for CSI; e) IPC and LPE, and IPC and BPE for ISA; f) SPC and LPE, and SPC and BPE for IMA. Conclusion: The radiographic indexes and angles created provided differentiation parameters between patients with different types of pectus, and between these and controls.

title: IMPACT OF COVID-19 ON MORTALITY AND HOSPITALIZATION IN OLDER ADULTS WITH HIP FRACTURE

description: ABSTRACT Objective: To evaluate the impact of the COVID-19 pandemic on hospital admission and mortality indicators in older adults with fractures of the proximal femur. Methods: Observational and retrospective study that took place from June 2016 to 2020. Patients of both genders who underwent surgical treatment for fractures of the proximal end of the femur, aged over 60 years, were included. Results: The population consisted of 379 patients, treated before (group 1; N = 278; 73.35%) and during the pandemic (group 2; N = 101; 26.65%). Higher mortality was observed in group 2 (N = 24; 23.8%) versus group 1 (N = 10; 3.6%), p &lt; 0.001. The highest proportion of deaths in group 2 was maintained in patients aged 70-79 years (p = 0.011), 80-89 years (p ≤ 0.001) and &gt; 90 years (p ≤ 0.001). In addition, the preoperative time and hospital stay were longer in group 2 compared to group 1 (p ≤ 0.001). Conclusion: The present study demonstrated that the pandemic period increased the mortality rate and the preoperative and hospitalization time in older patients with femur fractures. Thus, the pandemic has affected the care of fractures of the proximal femur in older adults, which reinforces the need to adopt measures to reduce complications and mortality. Level of Evidence II, Retrospective Study.

title: The role of cultural heritage in the admission exams for the Brazilian diplomatic career between 1995-2015

description: Abstract The selection of new members to occupy positions in the Brazilian federal bureaucratic framework changed progressively during the second half of the 1990s. If the initial orientation was characterized by the quantitative resumption of federal public tenders (1995-2002), post-2003, this trend sought to attract a greater diversity of social sectors in public careers — and the selection of diplomats was not alien to this process. The qualitative analysis of primary sources (documents) and secondary sources (literature review) showed that, along with initiatives already recognized in the literature — increase in the number of vacancies and remuneration, exemption from registration, among others — the very modification of questions formulated in the exams applied between 1995 and 2015 can be understood as a measure toward the alteration of the profile of those entering the diplomatic career. Between 1995 and 2004, the test evaluated and selected the candidates through questions of “general culture,” which privileged a certain “cultural heritage” reputed as a sign of social distinction and associated with an allegedly sophisticated social profile. However, between 2004 and 2015, there seems to have been a standardization of the new questions, which, moving away from the tacit requirements of cultural refinement, gave preference to other candidate profiles.

title: Salivary metabolomic profile in adolescents with juvenile systemic lupus erythematosus

description: Abstract The aim of this study was to characterize the salivary metabolomic profile in adolescents with juvenile systemic lupus erythematosus (jSLE). A total of 24 adolescents with jSLE (15.92 ± 2.06 years) and 12 systemically healthy controls (15.25 ± 2.7 years) were included in the study. Participants underwent rheumatologic testing and periodontal examination, with the recording of plaque index (PI), probing depth (PD), clinical attachment level (CAL), and bleeding on probing index (BPI). Unstimulated whole saliva was collected from both groups and stored at -80 ºC. The salivary proton nuclear magnetic resonance (1H-NMR) spectra were acquired in a spectrometer operating at 500 MHz. Partial least squared discriminant analysis (PLS-DA) and orthogonal PLS-DA (O-PLS-DA) were used for statistical analysis. Mean CAL and PI were significantly increased in the group with jSLE (p &lt; 0.01). Patients with jSLE presented a significantly different salivary metabolic profile (accuracy = 0.54; R2 = 0.86; Q2 = -0.293), significantly higher salivary levels of N-acetyl sugars, and significantly reduced levels of phenylalanine, glycine, taurine, hydroxybutyrate, and valerate compared with healthy controls (p &lt; 0.05). It is suggested that the salivary metabolomic profile analyzed by 1H NMR in patients with jSLE presents a different fingerprint that the systemically healthy subjects. Integrating the variation of metabolites with the identification of the metabolic pathways involved seems to provide a better understanding of the influence of systemic disease on salivary metabolites.

title: Self-made home: how and where does the anuran Rhinella dorbignyi build its retreat sites

description: ABSTRACT In this study, we observed that burrows of Rhinella dorbignyi (Duméril & Bibron, 1841) are distributed in a non-random manner in the habitat, suggesting a microhabitat selection for digging. This conclusion was based on a characterization of 36 burrows and surrounding micro-habitat. We established a 1 m x 1 m quadrat with the burrow in its central point (n=36) to measure the percentage (density) and the average heights of grasses, herbs, and shrubs. All measurements were repeated in two unused quadrats (without burrows) to evaluate the available microhabitat (n=72). The burrows are built in specific areas of the habitat with a higher percentage of grass, taller herbs, lower density of shrubs and low shaded sites than the founded at control sites. Based on three-dimensional models of the interior of the burrow (n=15), we observed that all of them were constructed with an elliptical opening that opens into a narrow channel perpendicular to the ground. Channels had a mean maximum diameter of 38 mm and a mean minimum diameter of 18 mm. The mean length of the burrows is 182 mm, and the mean volume is 95 mL.

title: Genetic diversity of Trypanosoma cruzi strains isolated from chronic chagasic patients and non-human hosts in the state of São Paulo, Brazil

description: BACKGROUND Trypanosoma cruzi shows an exuberant genetic diversity. Currently, seven phylogenetic lineages, called discrete typing units (DTUs), are recognised: TcI-TcVI and Tcbat. Despite advances in studies on T. cruzi and its populations, there is no consensus regarding its heterogeneity. OBJECTIVES This study aimed to perform molecular characterisation of T. cruzi strains, isolated in the state of São Paulo, to identify the DTUs involved and evaluate their genetic diversity. METHODS T. cruzi strains were isolated from biological samples of chronic chagasic patients, marsupials and triatomines through culture techniques and subjected to molecular characterisation using the fluorescent fragment length barcoding (FFLB) technique. Subsequently, the results were correlated with complementary information to enable better discrimination between the identified DTUs. FINDINGS It was possible to identify TcI in two humans and two triatomines; TcII/VI in 19 humans, two marsupials and one triatomine; and TcIII in one human host, an individual that also presented a result for TcI, which indicated the possibility of a mixed infection. Regarding the strains characterised by the TcII/VI profile, the correlation with complementary information allowed to suggest that, in general, these parasite populations indeed correspond to the TcII genotype. MAIN CONCLUSIONS The TcII/VI profile, associated with domestic cycles and patients with chronic Chagas disease, was the most prevalent among the identified DTUs. Furthermore, the correlation of the study results with complementary information made it possible to suggest that TcII is the predominant lineage of this work.
