title: Efficacy of removal of cariogenic bacteria and carious dentin by ablation using different modes of Er:YAG lasers

description: The primary objective of this in vitro study was to evaluate the efficiency of removal of cariogenic bacteria and carious dentin by ablation using two lasers: fluorescence-feedback controlled (FFC) Er:YAG laser and different pulses of Er:YAG laser based on variable square pulse technology (VSPt). The secondary objective was to measure the temperature during laser ablation of carious tissue. Seventy-two extracted human molars were used in this study. Sixty teeth with carious dentin were randomly divided into four experimental groups according to the treatment for caries removal: group 1: 400 µs (FFC group); group 2: super short pulse (SSP group, 50 µs pulse); group 3: medium short pulse (MSP group, 100 µs pulse); group 4: short pulse (SP group, 300 µs pulse) and one positive control group with no treatment. Twelve teeth without carious lesion were used as a negative control group. After caries removal, swabs were taken with cotton pellets and real-time PCR analysis was performed. During caries ablation, a thermal infrared camera was used to measure the temperature changes. In all experimental groups, specimens were free of bacterial contamination after the treatment. In the SSP, MSP and SP groups, temperatures measured during caries ablation were significantly higher compared to temperatures in the FFC group (P&lt;0.001). In this in vitro study, laser treatment for removal of carious dentin and cariogenic bacteria was an efficient treatment modality without causing excessive temperatures that might adversely affect pulp vitality.

title: Penile microvascular endothelial function in hypertensive patients: effects of acute type 5 phosphodiesterase inhibition

description: The primary aim of this study was to evaluate penile endothelial microvascular function in patients with primary arterial hypertension and age-matched normotensive subjects using laser speckle contrast imaging (LSCI). Additionally, we analyzed the acute penile microvascular effects induced by oral phosphodiesterase type 5 inhibitor (sildenafil; SIL) administration. Endothelium-dependent microvascular reactivity was evaluated in the penises and forearms of hypertensive patients (aged 58.8±6.6 years, n=34) and age-matched healthy volunteers (n=33) at rest and 60 min following oral SIL (100 mg) administration. LSCI was coupled with cutaneous acetylcholine (ACh) iontophoresis using increasing anodal currents. Basal penile cutaneous vascular conductance (CVC) values were not significantly different between control subjects and hypertensive individuals. Penile CVC values increased significantly after SIL administration in control (P&lt;0.0001) and hypertensive (P&lt;0.0001) subjects. Peak CVC values were not different between the two groups during penile ACh iontophoresis before SIL administration (P=0.2052). Peak CVC values were higher in control subjects than in hypertensive subjects after SIL administration (P=0.0427). Penile endothelium-dependent microvascular function is, to some extent, preserved in patients presenting with primary arterial hypertension under effective anti-hypertensive treatment. LSCI may be a valuable non-invasive tool for the evaluation of penile vascular responses to phosphodiesterase type 5 inhibitor.

title: Organic solvent exposure and contrast sensitivity: comparing men and women

description: The goal of this study was to compare the visual contrast sensitivity (CS) of men and women exposed and not exposed to organic solvents. Forty-six volunteers of both genders aged between 18 and 41 years (mean±SD=27.72±6.28) participated. Gas station attendants were exposed to gas containing 46.30 ppm of solvents at a temperature of 304±274.39 K, humidity of 62.25±7.59% and ventilation of 0.69±0.46 m/s (a passive gas chromatography-based sampling method was used considering the microclimate variables). Visual CS was measured via the psychophysical method of two-alternative forced choice using vertical sinusoidal gratings with spatial frequencies of 0.2, 0.5, 1.0, 2.0, 5.0, 10.0, and 16.0 cpd (cycles per degree) and an average luminance of 34.4 cd/m2. The results showed that visual CS was significantly lower (P&lt;0.05) in the following groups: i) exposed men compared to unexposed men at frequencies of 0.2, 0.5, 1.0, and 2.0 cpd; ii) exposed women compared to unexposed women at a frequency of 5.0 cpd; and iii) exposed women compared to exposed men at a frequency of 0.5 cpd, even at exposures below the tolerance limit (300 ppm). These results suggest that the visual CS of exposed men was impaired over a wider range of spatial frequencies than that of exposed women. This difference may have been due to the higher body fat content of women compared to that of men, suggesting that body fat in women can serve as a protective factor against neurotoxic effects.

title: Functional evaluation of pediatric patients after discharge from the intensive care unit using the Functional Status Scale

description: ABSTRACT Objective: To evaluate the functional status of pediatric patients after discharge from the pediatric intensive care unit using the Functional Status Scale and to compare the time of invasive mechanical ventilation, length of stay in the pediatric intensive care unit, and Pediatric Index of Mortality 2 results among individuals with different degrees of functional impairment. Methods: A cross-sectional study was conducted on patients who were discharged from a pediatric intensive care unit. The functional evaluation by the Functional Status Scale was performed on the first day after discharge from the unit, and the Pediatric Index of Mortality 2 was used to predict the mortality rate at the time of admission to the pediatric intensive care unit. Results: The sample consisted of 50 individuals, 60% of which were male, with a median age of 19 [6 - 61] months. The overall score of the Functional Status Scale was 11.5 [7 - 15], and the highest scores were observed in the "motor function" 3 [1 - 4] and "feeding" 4 [1 - 4] domains. Compared to patients who were not readmitted to the pediatric intensive care unit, patients who were readmitted presented a worse overall score (p = 0.01), worse scores in the "motor function" (p = 0.01), "feeding" (p = 0.02), and "respiratory" (p = 0.036) domains, and a higher mortality rate according to the Pediatric Index of Mortality 2 (p = 0.025). Conclusion: Evaluation of the functional status using the Functional Status Scale indicated moderate impairment in patients after discharge from the pediatric intensive care unit, mainly in the "motor function" and "feeding" domains; patients who were readmitted to the pediatric intensive care unit demonstrated worse overall functional, motor function, feeding and respiratory scores. Individuals with greater functional impairment had longer times of invasive mechanical ventilation and hospitalization in the pediatric intensive care unit.

title: Empathic understanding and possible contributions to research in organizational studies: reflections from the experience of the aesthetic side of organizations

description: Abstract The method of Weberian understanding has been the subject of discussion and debate over time. However, specifically, empathic understanding is still little explored, especially in the study of Brazilian organizations. After searching on major databases and journals hosted on the website Periódicos CAPES, we found that there is little academic literature that follows the path of empathic understanding, specifically in the field of Organizational Studies in Brazil. Therefore, we seek to bring in this study some considerations about the rescue of empathic understanding for the research. Considering the approach of organizational aesthetics as a backdrop, the discussion articulates the epistemological foundations of empathic understanding proposed by Weber’s sociology. This recommends that studies in the field of Social Sciences are anchored primarily in understanding the meaning of individual action to understand why they act a certain way. Following the discussion, we reflect on the possible contributions that empathic understanding can bring to research, considering the idea of the researcher as a key to building the research corpus and the plausibility of knowledge obtained without necessarily undertaking the action. This article serves as a trigger for the development of other discussions about the possibilities of contribution of empathic understanding for the research in Organization Studies.

title: COLLECTIVE COMPETENCIES AND STRATEGIC PEOPLE MANAGEMENT: A STUDY CARRIED OUT IN FEDERAL PUBLIC ORGANIZATIONS

description: ABSTRACT Purpose: To identify whether public organizations that adopt the competency-based management model consider the collective component of competencies in their management practices. Originality/value: The academic literature highlights the potential of collective competencies to achieve organizational objectives, but there is a mismatch between the theoretical perspective and people management practices, which was confirmed throughout the study. Design/methodology/approach: The field research was carried out in three federal public organizations. Evidence was collected from documentary analysis and semi-structured interviews with ten employees from the respective Personnel Management areas. Findings: There was an isolated presence of attributes and sources of creation of collective competencies, which proved to be insufficient to determine their presence in the organizations under analysis.

title: Histological and nano-structured calcium phosphate bioceramic micro-macro porous granules in critical defect rabbits radius scanning electron microscopy evaluation

description: ABSTRACT The objective was to evaluate, through histologic exam and by scanning electron microscopy (SEM), the evolution of experimental critical defects in radio or not filled with nano-structured calcium phosphate micro-macro porous bioceramic granules rabbits. We used 70 rabbits, New Zealand, young adults, males, there was a critical defect in radio. The members were the groups: GI, slow bioceramic, GII, GIII and bioceramic moderate, negative control. After each experimental period, the animals were sacrificed and the radios harvested. Histological evaluations were performed at eight, 15, 30, 45, 60, 90 and 120 days and SEM analyzes at 60, 90 and 120 days. Histologically there was bone healing process earlier in GI and GII compared to GIII. In SEM we observed a higher proportion of mature bone and presence of secondary osteons in GI and GII, being more evident in the GII, confirming the histological findings. Ceramic promoted complete filling of the defect, while the control group was filling in the center of the defect, with empty spaces remaining on the sides. In conclusion, the use of bioceramics, slow and moderate absorption favor complete bone regeneration in critical defects being indicated as a bone substitute. The maturation occurs earlier when employing the ceramic moderate absorption.
