title: Is biochemical hypoglycemia necessary during an insulin tolerance test?

description: ABSTRACT Objective The insulin tolerance test (ITT) has been accepted as the gold standard test for assessing the integrity of the growth hormone (GH) – insulin-like growth factor (IGF-1) axis and the hypothalamic-pituitary-adrenal (HPA) axis. The goal of the test is to achieve clinical and biochemical hypoglycemia at a blood glucose level ≤ 40 mg/dL to effectively and correctly assess the HPA and GH-IGF-1 axes. In this study, the GH and cortisol responses of patients who achieved and failed to achieve biochemical hypoglycemia during an ITT were compared. Subjects and methods One hundred thirty-five patients with pituitary disorders were included in the study. Samples for blood glucose levels were obtained after clear symptoms of clinical hypoglycemia developed. The patients were enrolled in the hypoglycemic and nonhypoglycemic groups according to whether their plasma glucose level ≤ 40 mg/dL or &gt; 40 mg/dL during an ITT, and the groups were compared in terms of their GH and cortisol responses. Results The mean age, body mass index and waist circumference of the two patient groups were found to be similar. The mean blood glucose level was significantly lower in the hypoglycemic group than in the nonhypoglycemic group (19.3 and 52.0 mg/dL, respectively). When the two groups were compared in terms of peak cortisol and GH responses, no statistically significant differences were found. Conclusion The data presented suggest that clinically symptomatic hypoglycemia is as effective as biochemically confirmed hypoglycemia during an ITT. Arch Endocrinol Metab. 2020;64(1):82-8

title: Sucrose and substrates on the acclimatization of micropropagated Luehea divaricata plants

description: Abstract The objective of this study was to evaluate the effect of sucrose and substrates on the acclimatization of micropropagated Luehea divaricata plants. First, the effect of sucrose on in vitro growth and development of nodal segments in Woody Plant Medium reduced to its half concentration was tested. After that, these shoots were then acclimatized and the combined effect of sucrose, as previously described, plus the commercial substrates vermiculite, MecPlant® or H-decker® were tested. In the in vitro culture, root and leaf formation were superior (44%, 8.44 leaves) with 20 g L-1 sucrose, and then the presence of sucrose continued to be more efficient in the acclimatization with the MecPlant® or H-decker® commercial substrates. Sucrose at 20 g L-1 is more efficient for in vitro leaf and root formation, and the MecPlant® or H-decker® substrates may be used in acclimatization.

title: Influence of the ultrasonic activation of irrigating solutions on sealer penetration into lateral root canals

description: ABSTRACT Objective: This study analyzed the influence of the irrigating solutions ultrasonic activation on the obturator cement penetration into lateral root canals. Methods: Fifty maxillary molars (palatine root) were randomly assigned to 5 experimental groups (Group 1 (EDTA 17% + manual agitation for 5 minutes), Group 2 (EDTA 17% + ultrasonic activation for 15 seconds), Group 3 (NaOCl 1% + Ultrasonic activation for 15 seconds), Group 4 (EDTA 17% + ultrasonic activation for 15 seconds and NaOCl 1% + ultrasonic activation for 15 seconds) and Group 5 (negative control). The lateral root canals were made in the apical and middle third. The obturation occurred in a single session. The radiographic and microscopic analyzes were performed to evaluate the sealant cement penetration degree. Data were analyzed by the Mann-Whitney and Wilcoxon tests. Results: Apical and middle third radiographic analysis showed that Groups 2 and 4 presented better penetration of the sealant cement. In the microscopic analysis, Group 4 presented superior results in relation to the other groups in both thirds. In the apical third, radiographic and microscopic analyzes showed significant differences in the comparisons between Group 4 and Groups 5 (p = 0.019) and 3 (p = 0.023) and between Group 5 and Groups 2 (p = 0.012), 3 (P = 0.038) and 4 (p = 0.019), respectively. Conclusion: It was concluded that the ultrasonic activation of the NaOCl 1% + EDTA 17% irrigation solution provides greater penetration of the endodontic cement in lateral root canals.

title: Occupational Health: needs disregarded by the management of the Unified Health System

description: ABSTRACT This is a reflective essay that analyzes the Unified Health System's (SUS) operational and agreement rules. It shows that the normative statement resulting from health agreements is consistent with the constitutional provision of promotion, protection and rehabilitation of the worker's health and the epidemiological indicators of diseases resulting from work. It uses, as a method, the documentary and bibliographic analysis related to the subject and concludes that, based on the health needs, those that concern the worker's health are disregarded by the mechanisms of agreement and management of the health needs related to worker's health are disregarded by the pact mechanisms and management of the SUS.

title: Resistance of Soil Organic Matter in “Humic A Horizons” of the Mountainous Region in the State of Rio De Janeiro

description: ABSTRACT Soils with high organic carbon content, such as those with “humic A horizon”, occur in different regions of Brazil. This study aimed to determine the quantitative and qualitative characteristics of organic matter regarding the humic A horizon under different land uses in Bom Jardim, in Rio de Janeiro State, Brazil. Samples from forest, pasture, Eucalyptus plantation, coffee cultivation, olericulture, and also passion fruit soils were sampled and analyzed. In October 2011, undisturbed samples from humic A horizons, were collected for soil density analysis. In addition, disturbed samples were collected for the determination of organic carbon (Corg) content, total carbon, humic substance fractions contents and natural abundance of 13Carbon (δ13C). Low Corg contents were observed in areas under olericulture, pasture and passion fruit cultivation. The fulvic acid fraction was higher than other fractions, regardless of land use. The small variability in δ13C indicated maintenance of original Corg and suggest high resistance of Soil Organic Matter in humic A horizons.

title: Cooling of soybean seeds and physiological quality during storage

description: Abstract: The aim of this study was to evaluate the physiological quality of soybean seeds submitted or not to dynamic cooling, and kept in cold storage (CS) and non-cold storage (NCS). A soybean seeds lot, variety M7639RR, was divided into two parts, and each one was subdivided into three parts that were subjected to one of these cooling procedure: seeds without cooling (SWC), dynamic cooling at 17 °C (SC17), and dynamic cooling at 13 °C (SC13). Seeds were kept in CS and NCS at 20 °C. Samples were collected at six times (0, 45, 90, 135, 180 and 225 days), and then submitted to germination, tetrazolium, accelerated aging and seedling emergence tests. Dynamic artificial cooling at 13 °C followed by maintenance at 20 °C ensured the preservation of physiological quality of soybean seeds for up to 225 days. The vigor of the soybean seeds subjected to dynamic cooling at 13 °C was better preserved than that of the non-cooled or of the cooled at 17 °C ones and kept in NCS for 225 days. CS at 20 °C contributed to the preservation of the physiological quality of the soybean seeds, regardless of whether or not they were submitted to the dynamic procedure.

title: Fatigue resistance of endodontic instruments manufactured in NiTi CM Wire and in conventional NiTi alloy with eletrochemical treatment

description: ABSTRACT Objective: This study compared the fatigue behavior of endodontic instruments manufactured with conventional NiTi alloy electropolishing, RaCe (FKG Dentaire, LaChauxdeFonds, Switzerland), with instruments manufactured with NiTi CM Wire subjected to thermomechanical treatment, in the manufacturing process, HyFlex CM (Coltène Whaledent, Cuyahoga Falls, Ohio, USA), both with similar geometry and dimensions in order to determine the influence of the manufacturing process in the fatigue resistance. Methods: The methodoly consisted of twenty HyFlex CM and RaCe instruments with D0 0.25 mm, taper 0.06 mm / mm, 25 mm length, both with triangular cross section. The fracture resistance was evaluated by static fatigue test, using a stainless artificial canal with 5mm of radius (86°), recording the time and calculating the number of cycles until fracture occurs (NCF). For statistical analysis the Student t test was used The fractured instruments surface was analyzed by SEM. Results: The NCF was significantly higher for HyFlex CM instruments in comparison with RaCe files (P˂0.05) being 1336% more resistant to fatigue. The analysis of the fractured surface by SEM showed ductile-kind morphological characteristics for both instruments and the absence of plastic deformation. Conclusion: HyFlex CM instruments present higher values of NCF. Thus, it can be concluded that the thermal treatment to which these instruments with CM Wire alloy are submitted makes them more resistant to fracture than Race instruments manufactured with conventional NiTi alloy electropolishing.

title: Associated factors to the use of an emergency service, Ouro Preto, 2012

description: Abstract Objective to evaluate the association between selected sociodemographic, clinical and utilization variables and the inadequate use of an Emergency Care Service (ECS). Methods cross-sectional study with a sample of the 791 care attendances in an ECS during the year 2012 in Ouro Preto. The inadequate use of the ECS was evaluated using the Hospital Urgencies Appropriateness Protocol after descriptive and statistical analysis was performed using the Pearson chi-square test to detect associations between inadequate use and other variables. The binary Logistic Regression was used to estimate the odds ratio. Results 58.8% of the attendances were considered inadequate, with 78.7% of discharge after assistance. The utilization of the ECS in a working day had a greater chance of association with and inadequate care (CI=1.31-2.65). Conclusion The demand during working days and without referral to other health services was related to the inadequate use of the ECS. The percentage of inadequate attendances points to the need to implement a risk rating system in the ECS, better structuring of the health care network and educational activities among the population for guidance on how to more effectively use the urgent/emergency system the health region.

title: Burnout syndrome in informal caregivers of older adults with dementia: A systematic review

description: ABSTRACT Dementia is a constant concern for the public health system. Also, it impacts family members who provide informal care, often culminating in overload due to the emotional stress and physical distress of caregivers. Objective: This systematic review aimed to identify the consequences of Burnout Syndrome in informal caregivers of older adults with dementia. Methods: The search was performed spanning the last 10 years, in English, Portuguese or Spanish. The databases used were PubMed, SciELO, Web of Science and LILACS. The descriptors were obtained from MeSH and DeCS, which were, “caregivers”, “burnout”, “aged”, “psychological stress” and “dementia”. The selected articles included studies conducted with informal caregivers of community-dwelling older adults diagnosed with any type of dementia. The excluded articles had the following characteristics: the participants were not informal caregivers, the older adults were not diagnosed with dementia, or the main theme was not related to the Burnout Syndrome. Results: Initially, 1,208 articles were found. One hundred and forty-six were eliminated because they were duplicates. A further 1,033 were excluded because they did not meet the inclusion criteria. Twenty-nine studies were selected for full reading and 22 were excluded, giving 7 studies for inclusion in this review. Conclusion: The results showed that the Burnout Syndrome negatively affected caregivers’ quality of life and was associated with patient depressive and anxious symptoms and abusive behavior by caregiver. There is a need for studies with interventions addressing this issue.
