title: Influence of Gender and Undergraduate Course on the Knowledge about HPV and HPV Vaccine, and Vaccination Rate among Students of a Public University

description: Abstract Objective To evaluate the knowledge related to human papillomavirus (HPV) infection and the rate of HPV vaccination among undergraduate freshmen and senior students of medicine, pharmacy, speech therapy, nursing and physical education in a Brazilian university. Methods A questionnaire concerning sociodemographic aspects, sexual background, and knowledge about HPV and its vaccine was filled out by 492 students. Three months later, a second questionnaire, concerning the new rate of vaccination, was applied to 233 students. Results Among the 290 women who answered the first questionnaire, 47% of the freshmen and 13% of the seniors stated they were not sexually active, as well as 11% of the 202 freshman and senior male students. Although the knowledge about HPV was higher among women, they reported a lower use of condoms. More than 83% of the women and 66% of the men knew that HPV can cause cervical cancer, but less than 30% of the students knew that HPV can cause vulvar, anal, penile and oropharyngeal cancer. Less than half of the students knew that HPV causes genital, anal and oropharyngeal warts. Comparing the students, the seniors had more knowledge of the fact that HPV is sexually transmitted, and that HPV infection can be asymptomatic. The rate of vaccination was of 26% for women, and of 8% for men, and it increased to 52% and 27% respectively among the 233 students evaluated in the second questionnaire. Conclusion As almost half of freshman women declared being sexually inactive, the investment in public health information programs and easier access to the HPV vaccine seem to be a useful strategy for undergraduate students.

title: Modeling and simulation of an intelligent system for dosage control of post-chlorination in water treatment plants

description: ABSTRACT This paper presents an approach using a neural network model to control chlorine dosage in treated water, so as to obtain better results in the stability of the free residual chlorine, when compared to the control currently used, based on the Proportional-Integral-Derivative (PID) model and the consequent reduction in chlorine consumption in the water treatment process. Among the different disinfectants, chlorine is widely used in large water treatment plants in the world. In Brazil, especially in large cities, this chemical product is also used as a disinfectant agent. In this context, a neural model was implemented and simulated in MatLab software, taking into account the operational characteristics of a treatment plant, located in the São Paulo Metropolitan Region.

title: Advantages and disadvantages of teleworking in Brazilian public administration: analysis of SERPRO and Federal Revenue experiences

description: Abstract This study investigates the advantages and disadvantages of teleworking in public administration from the perception of 98 teleworkers and 28 managers at the Brazilian Federal Data Processing Service (SERPRO) and the Federal Revenue Service. Qualitative-quantitative research, consisting of questionnaires applied to teleworkers and interviews with managers, dealt with structural, physical, personal, professional, and psychological aspects. The results showed advantages such as better quality of life, work-family balance, greater productivity and flexibility, the possibility of creating standard metrics, better assessment of the workload, and reduction of costs, stress, commuting time, as well as less exposure to violence. As for disadvantages, the study identified elements such as non-adaptation, lack of communication and connection with the company, psychological problems, lack of infrastructure and control of the teleworker. The research concludes that teleworking requires a management model that makes it more adherent to the public sphere.

title: New entrants policy into agriculture: researching new farmers’ satisfaction

description: Abstract: During the last three decades, the European Union has adopted a series of policies aiming to increase the new farmers entering the primary sector. This scheme, namely the “New Entrants Policy”, is reflected to the relevant regulations of the Common Agricultural Policy. After many years of implementation, there is still limited information regarding young farmers’ perceptions and participation to this scheme. Against this backdrop, a questionnaire was developed in order to assess the degree of new farmer’s satisfaction on their decision to enter the agricultural sector by participating in this scheme. Furthermore, we tried to evaluate the factors and motivations that determined their decision. The survey was carried out in Greece during an educational seminar specifically designed for new entrants in agriculture. In total, 254 new farmers answered questions concerning their experience from the implementation of the program. Additionally, executives of public services involved in the program implementation were interviewed in depth. Data analysis revealed that the majority of new entrants declare a high degree of satisfaction from their decision to enter agriculture. Specifically, those who display environmental consciousness related to field practices towards environment protection feel more satisfied with their decision.

title: DNA nanovaccines prepared using LemA antigen protect Golden Syrian hamsters against Leptospira lethal infection

description: BACKGROUND Nanoparticles (NPs) are viable candidates as carriers of exogenous materials into cells via transfection and can be used in the DNA vaccination strategy against leptospirosis. OBJECTIVES We evaluated the efficiency of halloysite clay nanotubes (HNTs) and amine-functionalised multi-walled carbon nanotubes (NH2-MWCNTs) in facilitating recombinant LemA antigen (rLemA) expression and protecting Golden Syrian hamsters (Mesocricetus auratus) against Leptospira interrogans lethal infection. METHODS An indirect immunofluorescent technique was used to investigate the potency of HNTs and NH2-MWCNTs in enhancing the transfection and expression efficiency of the DNA vaccine in Chinese hamster ovary (CHO) cells. Hamsters were immunised with two doses of vaccines HNT-pTARGET/lemA, NH2-MWCNTs-pTARGET/lemA, pTARGET/lemA, and empty pTARGET (control), and the efficacy was determined in terms of humoral immune response and protection against a lethal challenge. FINDINGS rLemA DNA vaccines carried by NPs were able to transfect CHO cells effectively, inducing IgG immune response in hamsters (p &lt; 0.05), and did not exhibit cytotoxic effects. Furthermore, 83.3% of the hamsters immunised with NH2-MWCNTs-pTARGET/lemA were protected against the lethal challenge (p &lt; 0.01), and 66.7% of hamsters immunised with HNT-pTARGET/lemA survived (p &lt; 0.05). MAIN CONCLUSIONS NH2-MWCNTs and HNTs can act as antigen carriers for mammalian cells and are suitable for DNA nanovaccine delivery.

title: Strategies for eating and body change among Brazilian women and men

description: Abstract Objectives Our study was conducted to adapt the Body Image and Body Change Inventory (BIBCI) for Portuguese; to evaluate the BIBCI’s psychometric properties in samples of university students; to calculate the prevalence of strategies for eating and body change among students; and to evaluate the impact of demographic, social, and anthropometric characteristics on the BIBCI subscales. Methods 798 students (women = 63%) answered the Portuguese translation of the BIBCI and answered a demographic questionnaire. All analyses were performed separately for women and men. The BIBCI’s psychometric properties were estimated using confirmatory factor analysis. Mean scores were calculated for each BIBCI subscale. A multivariate regression model was tested to evaluate the impact of demographic, social, and anthropometric characteristics on mean BIBCI subscale scores. Results The psychometric properties of the BIBCI were adequate in the samples analyzed. The BIBCI subscales scores did not differ according to sex. According to the cut-off points adopted, most of the students were classified in the very low category of the BIBCI subscales. For women, characteristics such as self-reported eating assessment, economic class, physical activity level, and work were significant. For men, only physical activity level was significant. Conclusion The Portuguese translation of the BIBCI was presented and its psychometric properties were found to be adequate in the samples analyzed. The models identified significant characteristics that can be used in intervention protocols for preventing inappropriate behaviors in relation to body image and eating.

title: Genital Injuries: Are They Telling us Something about Sexual Violence?

description: Abstract Genital injury has a forensic relevance after a sexual assault and it has been discussed and investigated among professionals who work in this field. To analyze the studies published in the last decades, the present review examines different factors that may influence this finding, first clarifying terms of the forensic field, such as the peculiarity of the legal medical examination, and the distinction of the terms “legal” and “anatomical” vagina. Finally, it analyses if it is possible that the existence of these injuries in victims explain the lack of consent in sexual contact, and to clarify the meaning of the absence of injuries.

title: Optimization of a headspace solid-phase microextraction method for the gas chromatography-mass spectrometry analysis aroma compounds of Litsea mollis Hemsl. immature fruit

description: Abstract This study optimized using a headspace solid-phase microextraction (HS-SPME) method for extracting volatile aroma compounds, terpenoids in particular, from Litsea mollis Hemsl. immature fruit (LMIF). Gas chromatography-mass spectrometry was used to separate and identify volatile terpenoids in LMIF. The types of SPME fiber coating, salt addition, and desorption time were optimized by single factor-experiments to determine the range of extraction temperature. Built on insights from the single factor-experiments, the response surface methodology was further used to optimize the extraction temperature, extraction time, and equilibrium time of HS-SPME. The results showed that the optimal HS-SPME conditions for extracting volatile terpenoids from LMIF were: 50/30 μm of DVB/CAR/PDMS SPME fiber, 2.0 g of added sodium chloride, desorption at a temperature of 250 °C for 3 min, extraction and equilibrium temperature of 46 °C, extraction time of 36 min, and equilibrium time of 20 min. Under the above conditions, the predicted value of extraction was 66.92, while the experimental value was 65.78. The prediction value matched well with the experimental value with good repeatability. The designed model was proven to be valid, which can be applied for future extraction of aroma compounds from IMIF.

title: Defense mechanisms and quality of life of medical students according to graduation phase

description: Abstract Objectives To compare health-related quality of life (QoL) of medical students in initial and final phases of the program, and to evaluate the association between ego defense mechanisms and specific health-related QoL domains within each group. Methods This was an observational, cross-sectional study. Quality of life was assessed according to the World Health Organization Quality of Life instrument - Abbreviated Version (WHOQOL-Bref); anxiety and depression symptoms were evaluated using the Hospital Anxiety and Depression Scale (HADS); defense mechanisms were assessed using the Defense Style Questionnaire (DSQ-40) Results A total of 139 medical students were evaluated. Students in the initial semesters of the program (1st and 3rd) presented more depressive symptoms and worse quality of life in the psychological domain of WHOQOL-Bref when compared to those in the final semesters (8th and 12th). In a later analysis, conducted to identify the variables associated with the psychological domain of the WHOQOL-Bref for each group, both depressive symptoms and defense mechanisms were independently associated with the outcome for medical students in the beginning and in the end of the graduation program. Conclusions Students in the initial phases of medical school may need more specific attention from educational managers. Understanding the role of ego defense mechanisms in the quality of life of medical students may help identify effective psychopedagogical interventions for this population. In addition, the results reinforce the impact of depressive symptoms on quality of life, an association already well evidenced in the literature.
