title: Preliminary data for performance in hue ordering tests during pregnancy

description: The visual system of women changes during pregnancy. Few reports have addressed the effects of pregnancy on color vision. We aimed to compare the color vision of women in the first, second, and third trimesters of pregnancy. Fifty women were divided into first (n=10), second (n=10), third trimester pregnancy groups (n=10), and non-pregnant group (n=20). We used the Farnsworth D15 and Lanthony desaturated D15 (D15d) tests. The hue ordering quantified the amount of error (C-index) and the chromatic selectivity of the errors (S-index). Bland-Altman analysis was applied to the hue ordering data. No difference was found for Farnsworth D15 test results obtained from the pregnant groups and the non-pregnant group (P&lt;0.0083). For the Lanthony D15 desaturated test, the third trimester pregnant group had higher C-index and S-index than non-pregnant women and first-trimester pregnant women (P&lt;0.0083). The Bland-Altman analysis showed that the limits of agreement increased as pregnancy advanced, and the errors were biased to the D15d test. In this study, color vision was impaired during pregnancy. Color vision evaluation could be used as an indicator of the functional status of the central vision during pregnancy.

title: The effects of physical activity on anxiety, depression, and quality of life in elderly people living in the community

description: Abstract Introduction: Health problems may negatively affect the psychological and physical aspects of life, influencing the quality of life of older adults. The objective of this study was to analyze the effects of physical activity on quality of life, anxiety, and depression in the elderly population. Methods: We performed a cross-sectional study of 200 elderly people of both genders. Subjects were divided into two groups: one with 100 senior citizens engaged in physical activities in a social center for the elderly; and another composed of 100 subjects who lived in the community but were not engaged in physical activities. The instruments used to assess physical activities, quality of life, and anxiety and depression were, respectively: the modified Baecke questionnaire; the 36-Item Short Form Health Survey (SF-36); and the Hospital Anxiety and Depression Scale (HADS). The data were analyzed using the Student's t test, Pearson's r, and analysis of variance (ANOVA), with odds ratio and a 5% significance level (p&lt;0.05). Results: We observed that the active group showed higher scores of physical activity and quality of life. Conversely, the sedentary group revealed higher scores of anxiety and depression. Data assessment revealed a strong correlation between the domains quality of life, level of vitality, and mental health (r=0.77). The prevalence ratio showed that physical activity is a protective factor against anxiety and depression in the elderly. Conclusion: The findings suggest a correlation between low levels of physical activity and symptoms of anxiety and depression in the elderly living in the community.

title: Content validity of an educational workshop based on the Dietary Guidelines for the Brazilian Population

description: ABSTRACT Objective To describe the development and validation of a workshop protocol for the implementation of the Dietary Guidelines for the Brazilian Population in primary healthcare units. Methods This descriptive study was developed in the state of São Paulo, Brazil, and it involved 20-25 professionals in the experimentation phase and 12 experts in the content validity phase. The workshop protocol was developed according to three theoretical references: Dietary Guidelines, Interprofessional Collaborative Practice and Critical Reflexive Methodology. The protocol consisted of four 4-hour modules, 16 activities in 16 hours. The activities matrix was composed of three axes: (a) organizational strategies, (b) dietary guideline comprehension and (c) dietary guideline implementation. For the validity analysis, the expert panel assessed clarity, relevance and theoretical representativeness. Content validity index was calculated, and adequate activities scored &gt;0.80. The proportion of experts who recognized the presence of the theoretical framework in the activities was calculated. Results All 16 proposed activities obtained a score greater than the established cut-off point, both for clarity and relevance. For theoretical representativeness analysis, the dietary guidelines reached higher scores on the (b) and (c) axes of the protocol and was less recognized on the (a) axis, whose highest score was for the Critical Reflexive Methodology. Interprofessional Collaborative Practice presented a higher score on the (c) axis and a lower one on the (b) axis. Conclusion The protocol was considered appropriate for its purpose and with potential application in the different scenarios of primary health care in Brazil.

title: Encapsulating TiO2 into Polyvinyl Alcohol Coated Polyacrylonitrile Composite Beads for the Effective Removal of Methylene Blue

description: In this work, novel nanocomposite beads based on polyvinyl alcohol (PVA) coated polyacrylonitrile (PAN) with encapsulation of TiO2 nanoparticles (PPT) were developed successfully via a novel green synthetic method and its methylene blue (MB) removal ability by adsorption was also investigated. As-prepared nanocomposite beads were characterized by different techniques such as Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). TiO2 nanoparticles were encapsulated into the composite beads to endow the composite beads with photocatalytic ability and enhance its adsorption capacity for MB. Batch experiments with several variables such as TiO2 nanoparticle content, pH of the solution, contact time and initial MB concentration were carried out. The adsorption kinetic study revealed that the MB adsorption process agreed well with pseudo-second order model and showed 3-stage intraparticle diffusion model. The adsorption isotherm study indicated that the MB adsorption process could also be better described by Langmuir isotherm model. According to Langmuir isotherm equation, the maximum adsorption capacity and removal rate for MB was 242.13 mg g-1 and 98.4%, respectively. Moreover, the stability and reusability of as-prepared PPT beads were further explored and results demonstrated that PPT could be reused at least five times with negligible loss of sorption capacity and removal rate. Therefore, PPT is expected to be a potential candidate for effluents treatment.

title: Genotyping of South American clinical isolates of Pythium insidiosum based on single nucleotide polymorphism-based multiplex PCR

description: ABSTRACT: We aimed to genotype the South American clinical isolates of Pythium insidiosum using the single nucleotide polymorphisms (SNP) of the ribosomal DNA sequences (rDNA). Previously, an SNP-based multiplex-PCR was able to distinguish three different clades of P. insidiosum isolates. Thus, we used this assay to evaluate South American clinical isolates of P. insidiosum (n=32), standard strains from Costa Rica (n=4), Thailand (n=3), Japan (n=1), and India (n=1), a standard strain of Pythium aphanidermatum, and Brazilian environmental isolates of Pythium torulosum, Pythium rhizo-oryzae and Pythium pachycaule voucher (n=3). It was possible to allocate each American P. insidiosum isolate to clade I, the isolates of India, Japan, and Thailand to clade II, and the Thai isolate to clade III. P. aphanidermatum, P.torulosum, P.rhizo-oryzae and P.pachycaule voucher isolates were not amplified. For the first time, a P. insidiosum isolate from Uruguay, South America, was included in molecular analyzes. By SNP-based multiplex-PCR, it was possible to perform the identification and genotyping of the South American isolates of P. insidiosum, demonstrating similar genetic characteristics of these isolates.

title: Potential Slow Release Fertilizers and Acid Soil Conditioners Obtained by One-Pot Mechanochemical Activation of Chrysotile:Cement Roofing Sheets with K2HPO4

description: Chrysotile:cement roofing sheets were milled with and without K2HPO4. As indicated by X-ray diffraction (XRD), the samples crystallinities were reduced with the increasing milling time. The same tendency was observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), with disaggregation of the chrysotile fiber bundles and formation of non-fibrous micrometric agglomerate particles. After milling for 16 min, most of the phases present in the cement and chrysotile were transformed into amorphous materials, except quartz, in which the structure integrity was preserved, and calcium carbonate, where the particles were reduced to nanometric size. Both milled samples were submitted to release experiments in water, where the characteristics of a potential slow release fertilizer and acid soil conditioner were observed. The process is a viable alternative not only to eliminate the hazard of chrysotile fibers without the need to remove them from the cement matrix, but also as aggregation value to the milled almost amorphous mixture.

title: C1-C2 fractures in asymptomatic elderly patients with minor head trauma: evaluation with a dedicated head CT protocol

description: Abstract Objective: To evaluate the frequency and types of upper cervical spine injuries in asymptomatic elderly patients undergoing computed tomography (CT) for the investigation of minor head trauma. Materials and Methods: This was a prospective study of 2613 asymptomatic elderly patients with minor head trauma seen between January 2015 and December 2016. We adopted a dedicated head CT protocol that included the C1-C2 region. Results: Of the 2613 patients analyzed, 33 (1.26%) had upper cervical spine injuries, corresponding to 8.37% of the 394 patients with trauma-related findings. Of those 33 patients, 6 had C1 fractures and 27 had C2 fractures. The use of 16- and 128-slice scanners increased the CT dose by 25.0% and 23.7%, respectively. Conclusion: Inclusion of the C1-C2 region in head CT scans allowed us to identify upper cervical spine injuries in 1.26% of asymptomatic elderly patients with minor head trauma. The protocol evaluated helps detect potentially life-threatening injuries and could be adopted for routine use in elderly individuals with minor head trauma.

title: Preliminary analysis of N-vinylpyrrolidone based polymer gel dosimeter

description: Abstract This paper aims to evaluate the dosimetric characteristics of modified VIPARnd for radiotherapy dosimetry using optical investigations. The absorbance spectrum of the irradiated gel dosimeter was evaluated optically with spectrophotometer techniques and with a CMOS imaging system. The useful dose range for the peak value and the relative area under the absorbance curve is 3-20 Gy. The dose-response curve for CMOS readout has an interval of linearity from 3-20 Gy. The modified VIPARnd developed has a good dose range and good temporal stability in the spectrophotometric analysis of the intervals studied. The CMOS readout is transportable, cheaper, easier to use and an excellent alternative for dosimetry.

title: Should Sinus of Valsalva be Replaced in Patients with Dilated Ascending Aorta and Aortic Valve Diseases?

description: Abstract Introduction: The aim of this study is to investigate the change in the dimension of sinus of Valsalva in patients who underwent supracoronary ascending aorta replacement with aortic valve replacement. Methods: A total of 81 patients who underwent supracoronary ascending aorta replacement with aortic valve replacement were included. Ten of 81 patients died during the follow-up. The patients were divided into three groups according to the aortic valve diseases. Group I (n=17) included patients with bicuspid valves, group II (n=30) included patients with stenotic degenerative valves, and patients with aortic regurgitation constituted group III (n=24). In preoperative and follow-up periods, the sinus of Valsalva diameter of the patients was evaluated by echocardiographic examination. The mean age was 54.1±15.1 years. Twenty-eight (34.6%) patients were female and 12 (14.8%) patients were in New York Heart Association functional class III. Results: There was no early mortality. Late mortality was developed in 10 (12.4%) patients, 8 (9.9%) due to non-cardiac reasons. Late follow-up was obtained in 71 patients with a mean of 60±30.1 months postoperatively. During follow-up, the increase in the diameter of the sinus of Valsalva was significant in Group I (P&lt;0.01), while in Group II and III it was insignificant (P&gt;0.05). Conclusion: To avoid the risks associated with sinus of Valsalva dilatation, it is reasonable to replace the sinus of Valsalva in the setting of aortic valve replacement and ascending aorta replacement for bicuspid aortic valve with a dilated ascending aorta and relatively normal sinuses of Valsalva in young patients.

title: The Importance of Intra-aortic Pulse Pressure After Anterior ST-segment Elevation Myocardial Infarction

description: Abstract Objective: To evaluate the association of pulse pressure (PP) with mortality and major adverse cardiac events (MACE) in one-year period after anterior ST-elevation myocardial infarction (A-STEMI). Methods: A total of 261 consecutive patients whose blood pressure was measured with the aid of a catheter before primary percutaneous coronary intervention (PPCI) between August 2016 and February 2017 were included in the study. The patients were divided into three groups according to pulse pressure (PP) (Group 1, PP&lt;35 mmHg; Group 2, 35≤PP≤50 mmHg; Group 3, PP&gt;50 mmHg). Results: The mean age of the patients was 63.4±14.1 years, and 206 of them were male. The groups were similar in terms of age and diastolic blood pressure (DBP). The ratio of female patients in Group 1 was higher, and their systolic blood pressure (SBP) was lower than those from the other groups (P=0.005 vs. P=0.042). The rates of MACE and mortality were higher in Group 1. The predictive PP values were calculated to be 42.5 mmHg for development of MACE and 41.5 mmHg for mortality. One-year survival ratio was worse in Group 1 than in the others according to Kaplan-Meier analysis (P&lt;0.001). Conclusion: The values of PP which was measured intra-aortically in patients with A-STEMI were associated with mortality and MACE in the one-year follow-up period.

title: Synthesis, characterization and antibacterial activity of novel poly(silyl ether)s based on palm and soy oils

description: Abstract In this research, palm oil and soy oil were used as a natural polyol to prepare novel poly(silyl ether)s. Palm oil and soy oil were first converted to monoglyceride by one step via alcoholysis process in the presence of 0.1% CaO as a catalyst. The monoglycerides were characterized by Fourier transform infrared spectrometer (FT-IR), nuclear magnetic resonance (NMR) and iodine test. The novel poly(silyl ether)s were prepared via polycondensation reaction between dimethyldichlorosilane with monoglycerides based on palm and soy oils, respectively. FT-IR, NMR and silicone-29 (29Si NMR) were used to confirm and determine the presence of silicone in the synthesized polymers. Thermal behavior was studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Antibacterial activity of the polymers was screened against three different strains of bacteria, namely Escherichia coli E266, Staphylococcus aureus S276 and Salmonella choleeraesuis 10708.
