NUTRITIONAL PROPERTIES OF CHIA SEEDS AND THEIR SANITARY SAFETY
Authors: Valevskaya L. , Iegorova A. , Ovsiannykova L. , Sokolovskaya O. , Marchenkov F. , Shulyanska A.
Published: July 2020

Currently, there are more and more requirements not only to the quality of food, but also to the raw materials it is made from. This leads to the search for new, non-traditional products. One of these is chia seeds (Salvia hispanica). The article provides data on their useful properties. The high demand for chia seeds is due to their unique chemical composition. The main feature of the seeds of this crop is that they contain many chemical substances of high calorific and biological value, as compared with cereals and oilseeds traditionally grown in Ukraine. In chia seeds, there are 30–35% of fat, 25–41% of carbohydrates, and 20–22% of protein. Chia seeds are a valuable source of vitamin B, calcium, potassium, iron, zinc, and copper. The fatty acid composition of this crop indicates a high content of polyunsaturated fatty acids. 63.3% of them is linolenic fatty acid, which belongs to ω-3 acids and is important for the brain function, growth, and development of a living organism. That is why it is so important to find optimal ways of preparing freshly harvested chia seeds so as to extend their shelf life. These ways must take into account the biological and chemical characteristics of this crop, and make it possible to preserve its consumer properties for further targeted processing. The article presents the results of studying the quality indicators and microbiological condition of chia seeds to establish how long they can be safely stored and to assess the sanitary safety of this crop. It has been shown that within the period of 6 months, the greatest changes in the quality of chia seed oil are observed at 25°C: there is a significant increase in the acid and peroxide values and a decrease in the iodine value (the latter indicates spoilage of chia seeds). Lowering the air temperature to 5°C slows down the enzymatic processes that take place in chia seeds, and inhibits the increase of the acid and peroxide values of fat, which ensures retention of the consumer properties of seeds. It has been established that the seeds of the crop under study can be stored, without any loss of their quality, for 6 months at 5–15°C and the relative humidity 60–70%. All the beneficial properties of chia seeds are due to their unique composition, so they are supposed to be widely used for specialised and functional nutrition
FEATURES OF THE CHEMICAL COMPOSITION OF CORN GRITS AT THE DIFFERENT DEGERMINATOR MODES IN THE DENT CORN PROCESSING
Authors: Rybchynskyi R. , Sots S. , Kustov I.
Published: July 2020

This article is devoted to the study of transforming the chemical composition of corn grits at the different operation modes of degerminator in the dent corn processing. The experiment was conducted in industrial conditions on Skvyrskyi grain processing factory Ltd. during the processing of kernels using the degerminator of Bühler company. The operation modes of the degerminator were changed for 5 times during the experiment by means of the regulation of the gap between the shell and the drum. The study has shown that in terms of the low operation mode of the degerminator (the passage of the sieve Ø3.0 – 34.9%) there is a high output of fine fractions of the intermediate products, but the quality level of the overtail product of the degerminator is the best by fat content 1.81% and crude fiber content 6.72%, which indicates a minimal germ and bran content. In case of the increase of the gap (the passage of the sieve Ø3.0 – 12.4%), the output of fine fractions of the intermediate products, as well as the output of feed germ meal, declines, at the same time the overtail product has the high number of remnants of the germ and bran after the degerminator, as the fat content increases to 2.80% and crude fiber content increases to 9.82%. It was also found that the change of degerminator modes (increase in the passage of the sieve Ø 3.0 from 34.9 to 12.4%) leads to a decrease in the starch content from 79.36 to 75.43%, the protein content does not change. In order to provide the high quality of corn groats products, it is advisable to control the quality of the overtail products of the degerminator by the fat content. The fat content in the overtail product must not be higher than 2.2% – during the production of long shelf life products, and not higher than 2.5% – during the production of common corn products. For prompt regulation of the degerminator operation modes, it was offered to use release indicator, which can be determined by means of sieving of the 100 g of the overtail products using the Ø 3.0 sieve. In order to provide the fat content in groats within 0.6–0.8% and 0.8–1.0%, the general extraction of the fine products (release indicator) with the Ø 3.0 sieve use in the dent corn processing should vary within the range of 27–32% and 22–27%, respectively.

Published: July 2020

This article is about the process and outcome of carrying out the author's Extended Project Qualification (EPQ). The title of her EPQ was: 'Is It Politically Possible to Keep Global Temperature Rise "Well below 2 °C"?' – using the wording of the Paris Agreement to focus on
the temperature threshold that scientists believe is safe for our planet. Detailing the international, national and local levels of politics combatting climate change, the EPQ led the author to research agreements, such as Paris, and national issues, such as the United Kingdom's electricity
generation. She discusses the value of the EPQ. It allowed her to explore a real-world issue, which not only made her more engaged in learning, but gave her a greater understanding of the world we live in.
From Climate Anxiety to Resilient Active Citizenship: when primary schools, parents and environmental groups work together to catalyse change
Authors: Pinto Rita Soares , Grove-White Sally
Published: July 2020

This article presents the perspectives and experiences of parents of primary school children who, as climate change activists, have been reflecting on the role of primary schools and actively engaging in their children's school by piloting a climate change action initiative in close
collaboration with environmental organisations. At the intersection of primary education, climate change and active citizenship for social change, this article contributes to the following questions: What is the role of primary schools regarding the current climate emergency? How can primary
schools contribute to building a generation of emotionally resilient, environmentally aware, proactive citizens? While the authors' professional backgrounds and work are not directly in education, they hope that reflections about active citizenship and social change can bring rich perspectives
on the role of schools and formal education on climate change. The first section reflects on the unique role of primary schools regarding the current climate emergency. The second section discusses the authors' own experience of setting up a Climate Action Group of parents, school staff, teachers
and pupils, and how they were able to support the school to put climate action at its core.

Published: July 2020

Abstract The objective of this work was to evaluate the effects of in vitro and in situ biodegradation on the surface characteristics of two resin cements and a hybrid ceramic system. One hundred and eighty specimens (4X1.5mm) of each material (Maxcem Elite, NX3 Nexus and Vita Enamic) were made and randomly distributed in twelve groups (n=15) according to the material and biodegradation method. The specimens were then submitted to the following challenges: storage in distilled water 37 ºC for 24 h or 7 days, storage for 7 days, at 37 ºC, in stimulated saliva or in situ. The in situ stage corresponded to the preparation of 15 intraoral palatal devices, used for 7 days. Each device presented 3 niches, where a sample of each materials was accommodated. Specimens from both saliva and in situ groups suffered a cariogenic challenge, corresponding to the application of a solution of 20% of sucrose, 10 times throughout each day. After each biodegradation method, the surface roughness (Ra), Vickers hardness (VHN) and scanning electron microscopy (SEM) analyzes were performed. The data collected were evaluated by Levene test, two-way ANOVA and Tukey`s test (α=5%). The in situ challenge promoted the greater biodegradation, regardless of the material. Regarding the materials, the Vita Enamic VHN was negatively affected by all biodegradation methods and the Nexus NX3 presented better performance than the self-adhesive cement tested. Therefore, within the conditions of this work, it was concluded that in situ biodegradation can affect negatively the surface characteristics of indirect restorative materials.

Published: July 2020

Abstract Caliber persistent labial artery (CPLA) consists in a dilated portion of the main branch of the labial artery without loss of size. The aim of this study is to report a case of a patient diagnosed with CPLA in the upper lip, emphasizing unusual histopathological and immunohistochemical findings. A 67-year-old female patient with complaint of a pulsating upper lip lesion without painful symptomatology. Under a clinical diagnosis of CPLA, and considering that the patient was edentulous and used a total prosthesis, an excisional biopsy of the lesion was performed to avoid future traumas in the region and consequently possible exuberant local bleeding. At anatomopathological examination structures suggestive of lymphoid follicles and germinal centers were visualized. Immunohistochemistry showed positivity for CD20, CD68, desmin and CD34 and negativity for CD4. The patient did not have a history of allergies, cardiovascular, rheumatic or systemic diseases that could justified the findings. The case presents unusual histopathological structures, evidencing the necessity of more studies about this pathology so scarce in the literature.

Abstract The purpose of this study was to investigate and to compare the physical-mechanical properties of a resin-modified calcium silicate material (TheraCal LC), used for pulp-capping, to MTA (Angelus) and a calcium hydroxide cement (Dycal). Specimens of each material (n=12) were prepared in Teflon molds (3.58 mm x 3 mm) and measured before and after immersion in distilled water for 24 h and 30 days to evaluate the dimensional change. The same specimens were submitted to compressive strength test on a Universal Testing Machine (Instron) (1 mm/min). Root canals were filled with the cements (n=8), and after 24 h, the bond strength (push-out test) to dentin was also assessed on a Universal Testing Machine (1 mm/min). Eight additional specimens of TheraCal LC were prepared to evaluate the bond strength immediately after light curing. Data were analyzed using One-Way ANOVA, and Tukey or Bonferroni post hoc tests (p<0.05). Percentage expansion of TheraCal LC was above the Specification No. 57 of ANSI/ADA, in both periods. The dimensional change for TheraCal LC was higher than MTA in 24 h and 30 days; and Dycal in 30 days (p<0.05). TheraCal LC had higher compressive and bond strength to dentin in comparison with MTA and Dycal (p<0.05). Although TheraCal LC expanded more than the ANSI/ADA recommendation, its compressive and push-out bond strength to dentin were satisfactory and superior to MTA and Dycal.

Abstract Chloride intracellular channel-4 (CLIC4) is regulated by p53 and tumor necrosis factor-α (TNF-α), it is linked to the increase of transforming growth factor-β (TGF-β), and myofibroblastic differentiation in skin carcinogenesis. This study analyzed the immunoexpression of CLIC4, p53, TGF-β, TNF-α, and α-SMA in 50 actinic cheilitis (AC) and 50 lower lip squamous cell carcinoma (LLSCC). AC and LLSCC immunoexpression were categorized as score 1 (<5% positive cells), 2 (5-50%) or 3 (>50%). For CLIC4, nuclear and cytoplasmic immunostaining of epithelial cells was considered individually. For morphologic analysis, the World Health Organization criteria were used to epithelial dysplasia grade of ACs, and Bryne grading of malignancy system was applied for LLSCC. Higher nuclear CLIC4 (CLIC4n) and TGF-β were observed in ACs with low-risk of transformation, while cytoplasmic CLIC4 (CLIC4c), p53 and TNF-α were higher in the high-risk cases (p<0.05). In LLSCCs, CLIC4c was higher in cases with lymph node metastasis, advanced clinical stages, and histological high-grade malignancy. p53 expression was higher in high-grade LLSCCs, whereas TGF-β decreased as the clinical stage and morphological grade progressed (p<0.05). ACs showed an increased expression of CLIC4n and TGF-β, while CLIC4c and α-SMA were higher in LLSCCs (p<0.0001). Both lesions showed negative correlation between CLIC4n and CLIC4c, while in LLSCCs, negative correlation was also verified between CLIC4c and p53, as well as CLIC4c and TGF-β (p<0.05). Change of CLIC4 from the nucleus to cytoplasm and alterations in p53, TGF-β, TNF-α, and α-SMA expression are involved in lip carcinogenesis.

Published: July 2020

Abstract Diabetes is a group of metabolic disorders that can lead to damage and dysfunction of many organs including the dental pulp. Increased inflammatory response, reduction of dentin formation and impaired healing were reported in diabetic dental pulp. Hyperglycemia, which is a main characteristic of diabetes, was suggested to play a role in many diabetic complications. Therefore our aim was to investigate the effects of high glucose levels on proliferation, reactive oxygen species (ROS) production and odontogenic differentiation of human dental pulp cells (HDPCs). HDPCs were cultured under low glucose (5.5mM Glucose), high glucose (25 mM Glucose) and mannitol (iso-osmolar control) conditions. Cell proliferation was analyzed by MTT assay for 11 days. Glutathione and DCFH-DA assay were used to assess ROS and antioxidant levels after 24 h of glucose exposure. Odontogenic differentiation was evaluated and quantified by alizarin red staining on day 21. Expression of mineralization-associated genes, which were alkaline phosphatase, dentin sialophosphoprotein and osteonectin, was determined by RT-qPCR on day 14. The results showed that high glucose concentration decreased proliferation of HDPCs. Odontogenic differentiation, both by gene expression and mineral matrix deposit, was inhibited by high glucose condition. In addition, high DCF levels and low reduced glutathione levels were observed in high glucose condition. However, no differences were observed between mannitol and low glucose conditions. In conclusion, the results clearly showed the negative effect of high glucose condition on HDPCs proliferation and differentiation. Moreover, it also induced ROS production of HDPCs.

Abstract This study aimed to quantitatively compare the difference in protein expression in the progression of pulp pathogenesis, as well as to describe the biological functions of proteins identified in pulp tissue. Samples were obtained from six patients treated at the Araçatuba School of Dentistry and were divided into three groups: normal pulp - from teeth extracted for orthodontic indication; inflamed pulp and necrotic pulp - from patients diagnosed with irreversible pulpitis and chronic apical periodontitis, respectively. After previous proteomic preparation, dental pulp samples were processed for label-free quantitative proteomic analysis in a nanoACQUITY UPLC-Xevo QTof MS system. The difference in expression between the groups was calculated using the Protein Lynx Global Service software using the Monte Carlo algorithm. A total of 465 human proteins were identified in all groups. The most expressed proteins in the inflamed pulp group in relation to the normal pulp group were hemoglobin, peroxiredoxins and immunoglobulins, whereas the less expressed were the tubulins. Expression levels of albumins, immunoglobulins and alpha-2-macroglobulin were higher in the necrotic pulp group than in the inflamed pulp group. As for the qualitative analysis, the most prevalent protein functions in the normal pulp group were metabolic and energetic pathways; in the inflamed pulp group: cellular communication and signal transduction; and regulation and repair of DNA/RNA, while in the necrotic pulp group proteins were associated with the immune response. Thus, proteomic analysis showed quantitative and qualitative differences in protein expression in different types of pulp conditions.

Published: July 2020

Abstract This study aimed to quantify the penetration of hydrogen peroxide, color change evaluation, surface morphology, and composition after application of desensitizing agents before in-office bleaching. Fifty premolars were sectioned, an acetate buffer was placed in the pulp chamber and divided into five groups (n=10). In the positive control group, only the in-office bleaching gel was used, and in the negative control group, no treatment was used. Three different desensitizing agents were applied: Desensibilize KF2%® group; Mi Paste® group, and Desensibilize Nano-P® group. The bleaching procedure was carried out with 35% HP. The absorbance of the resulting solution was determined in a spectrophotometer. Color change was assessed by using a digital spectrophotometer. Four additional premolars were assigned to the same groups above for analysis under scanning electron microscope, as well as to evaluate the elemental composition with X-ray dispersive energy spectrometry. Data were subjected to ANOVA and Tukey's test (α=0.05). All products reduced the penetration of HP in the pulp chamber. Mi Paste and Nano P were the products that yielded the lowest HP penetration, which was similar to the negative control group (p<0.001). No significant difference was detected in color change (p<0.001). Concerning enamel morphology, the groups that were analyzed after bleaching were observed a greater deposition of desensitizing agents on the surface. The use of desensitizing agents before tooth bleaching seems to be an alternative to reduce adverse effects of the tooth.

Abstract This in vitro study evaluated cell viability and metabolism, nitric oxide release and production of two chemokines and one cytokine by cultured human dental pulp fibroblasts (HDPF) in contact with two glass ionomer cements (Ketac Molar-KM and Vitrebond-VB), Single Bond (SB) and calcium hydroxide (Dycal-DY). Cultures of HDPF were established by means of an explant technique. The specimens were prepared under sterile conditions and in disks measuring 5 mm x 2 mm obtained from a prefabricated mold and placed on a permeable membrane to avoid direct contact with the cells. Cytotoxicity was assessed by Trypan Blue exclusion method and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Nitric oxide release in cell supernatant was detected by the Griess Method whereas stromal derived factor-1 alpha (SDF-1α or CXCL12), chemokine (C-X-C motif) ligand 8 [Interleukin 8 (IL-8 or CXCL8)] and interleukin-6 (IL-6) were detected by ELISA. RT-qPCR was employed for gene expression analysis. Statistical analyses were performed by One-way ANOVA followed by Tukey’s post hoc test for materials independent of the time, and Two-way ANOVA followed by Bonferroni correction test for the comparisons between materials and experimental time (p<0.05). Cytotoxic tests showed significant differences only for DY. Protein levels and mRNA expression were significantly increased for IL-8 for both periods of time. IL-6 production increased when fibroblasts were stimulated by KM. SDF-1α protein production and mRNA expression were not affected by any of the materials. There was a decrease in nitrate/nitrite levels only for KM. Although DY caused intense cell death and did not stimulate the production of the inflammatory mediators evaluated in this work, it is known that this event seems to be fundamental for the process of repair of the pulp tissue and formation of mineralized barrier. KM and VB increased production of proteins related to the inflammatory process, thus favoring tissue repair. Therefore, although these glass ionomer cements did not lead to large cell death, they should be used with caution.

Published: July 2020

ABSTRACT Owing to the exponential growth of the human population and problems related to food supply, research focused on finding the most suitable approach to manage and geographically explore the environment using sustainable technologies stand out. The present study aims to produce a consistent interpolation of historical series of enthalpy (H) resulting in a thematic map of enthalpy, using the spline method as a kriging option in areas with few sampling points. The thematic map considers thermal comfort conditions to produce broiler chickens, that could be used as a management tool to reduce power consumption due to the cooling process of the facilities. It was verified that spline is an efficient method to create a suitable thematic maps representations of areas presenting a few sampled units. The geographical representation of enthalpy allowed the evaluation of the environments, concluding that the state of Mato Grosso do Sul, Brazil is inadequate for broiler chickens production without suitable thermal cooling systems. Evidence suggests introduction of aviculture in areas still unexplored, e.g., Chapadão do Sul and Sete Quedas.

ABSTRACT The shoot maturation phase is important for growing mango tree because it precedes the floral induction, when plants are under stress caused by high temperatures and low water availability, that could be reduced by using plant biostimulant. Thus, the current study aimed to use a plant biostimulant containing yeast extract and amino acids to alleviate abiotic stress in mango plants, cv. Tommy Atkins, grown in semiarid environment. The experimental design consisted of randomized blocks with five treatments, five repetitions and five plants per plot. Treatments consisted of: T1) two foliar sprays with [biostimulant + KCl] + two foliar sprays with K2SO4; T2) No biostimulant and four foliar sprays with K2SO4; T3) three individual foliar sprays with biostimulant and one foliar spray with K2SO4; T4) two foliar sprays with biostimulant and two foliar sprays with K2SO4; and T5) two foliar sprays with [biostimulant + K2SO4] + one foliar spray with K2SO4. The variables evaluated were: i) leaf concentrations of soluble carbohydrates, starch, amino acids and proline; and ii) enzymatic activity of catalase and ascorbate peroxidase. The foliar spray with biostimulant during the branch maturation phase of mango trees grown in tropical semiarid environment alleviated plant abiotic stress. Three foliar biostimulant sprays and one K2SO4spray are recommended to alleviate mango plant abiotic stress in semiarid environment.

ABSTRACT Soil penetration resistance (SPR) is used as an indicator of compaction, as it is related to important soil and plant attributes and is an easily obtainable measure. Its determination with the use of the penetrometer guides to the best soil management strategies, thus favoring crop development. The objective of this study was to develop and validate the georeferenced hydraulic driven electronic penetrometer, making it easier to obtain SPR. For this, 36 SPR readings from 0 to 0.60 m depth were performed with the manual and hydraulic penetrometers in two areas. The SPR results were analyzed by establishing the confidence intervals by the t-test (p ≤ 0.10) at each 0.05 m depth and the georeferencing was analyzed through the root mean square error (RMSE). It was found that both penetrometers showed similarity in SPR measurement and in the georeferencing of the points.

ABSTRACT Objective: To describe children’s perception of risk and preventive factors related to traffic accidents using the Edutherapeutic Method. Methods: This is a qualitative descriptive study carried out with 173 students from public schools aged seven to 14 years in Lagarto, Sergipe, Brazil. Data were collected in the second half of 2014. The first stage consisted of an activity with drawing/writing sheets in all classes selected by the Nursing undergraduate students. Next, the children answered a questionnaire on sociodemographic data. The qualitative analysis of the expressive language of the children’s drawings generated two categories: positive and negative factors for the prevention of traffic accidents and their subcategories. Results: The children’s perception regarding preventive and risk factors for traffic accidents was considered adequate according to other studies found in the literature on the same subject. The drawings and descriptions were used later to provide the students with a better understanding of these factors. Conclusions: The study lends support to educational activities and interventions about prevention with schoolchildren. This is one of the main goals proposed by Brazil in the National Plan of Action for Road Traffic Safety for the decade 2011-2020.

Published: July 2020

ABSTRACT Objective: To evaluate the impact of pediatric asthma on patients of a specialized outpatient clinic in Southern Brazil. Methods: The study included children aged 8 to 17 years old with asthma diagnosis (mild, moderate and severe) under treatment at the asthma clinic of Hospital São Lucas da Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS), Brazil. Measurements of spirometry, quality of life, disease control and atopy tests were applied. Results: A total of 66 children were included in the study and divided into groups, according to the severity of the disease: mild, moderate or severe asthma. The results showed similarities in both the treatment and the impact of asthma between groups, except for adherence to treatment: the group with mild asthma showed least adherence to treatment, and the group with severe asthma, greater adherence (p=0.011). As to school absenteeism, the group with severe asthma showed higher frequency (p=0.012), with over 10 days per year (p=0.043). Spirometry showed lower volume/capacity for the group with moderate asthma, followed by the groups with severe and mild asthma. All groups had a high prevalence of allergic asthma, with mites as the main allergens. For quality of life (QOL), and health-related quality of life (HRQOL) levels, there were no differences between groups. In addition, the values were close to the acceptable levels for the total score and for each one of the six domains. The same occurred for the HRQOL-asthma module. Conclusions: QOL and HRQOL present acceptable levels regardless of the severity of the disease.
Cuerpos y mentes para el trabajo: la psicologización de los trabajadores en Bogotá y Medellín, 1946-1991
Authors: González Eugenio Castaño
Published: July 2020

Resumen En este artículo se pretende indagar la emergencia y desarrollo de una serie de discursos psicológico-administrativos sobre la motivación laboral, el clima organizacional y la calidad de vida en el trabajo, en ciudades como Bogotá y Medellín. Con ello se trata de dar cuenta del auge y expansión del conocimiento psicológico aplicado al mundo del trabajo y orientado a la optimización de rendimientos. La puesta en marca de estrategias de medición y cuantificación se erigieron en herramientas destinadas a objetivar comportamientos y fomentar una especie de reingeniería socio-laboral, en medio de un contexto caracterizado por la creciente inestabilidad laboral y el incremento del desempleo a finales de la década de 1980 y comienzos del 1990.
Ações pioneiras do ensino de pediatria no Brasil: Carlos Artur Moncorvo de Figueiredo (Moncorvo pai) e a Policlínica Geral do Rio de Janeiro, 1882-1901
Authors: Moreira Virlene Cardoso
Published: July 2020

Resumo O artigo analisa as atividades científicas de Carlos Artur Moncorvo de Figueiredo desenvolvidas na Policlínica Geral do Rio de Janeiro, fundada por ele. As ações profissionais e políticas desse médico foram fundamentais à implementação da pediatria, tanto no campo do estabelecimento de um espaço técnico de cura como na formação de uma cátedra especial de ensino da pediatria nas faculdades de medicina do Império, à época sediadas na Corte e em Salvador. O que se encontrará aqui é uma defesa de que a pediatria surgiu como desdobramento de um movimento pela implementação da medicina experimental, e não como uma questão social em torno do combate à mortalidade infantil, como comumente se encontra implícito na historiografia.

Published: July 2020

Abstract Objective: To analyze the association between gestational risk factors and type of delivery in high-risk pregnancies. Method: A cross-sectional epidemiological study involving a retrospective analysis of secondary data from 4,293 medical records of high-risk pregnant women. The primary outcome was composed of risks associated with cesarean delivery and spontaneous abortion compared with normal delivery. Results: There were 3,448 women analyzed in the study. The primary outcome rates were cesarean delivery (72.8%), spontaneous abortion (0.9%) versus vaginal delivery (26.2%). Common risk factors for cesarean delivery and spontaneous abortion were age ≥35 years (OR = 1.4; 95% CI 1.1-1.7 / OR = 11.5; 95% CI 4.2-31.0), evangelical religion (OR = 1.4; 95% CI 1.2-1.7 / OR = 2.6; 95% CI 1.0-6.7), high blood pressure (OR = 1.4; 95% CI 1.1-1.8 / OR = 74.9; 95% CI 13.7-410.2) and twinning (OR = 3.1; 95% CI 1.9-5.0 / OR = 68.6, 95% CI 9.7-487.7). Conclusion: Identifying the relationship of gestational risks with the type of delivery and abortion can contribute to developing strategies and assist in planning actions in women’s healthcare networks, developing specific and individualized lines of care for each gestational risk.
