title: Asymptomatic Plasmodium infection in a residual malaria transmission area in the Atlantic Forest region: Implications for elimination

description: Abstract INTRODUCTION: Elimination of malaria in areas of interrupted transmission warrants careful case assessment to avoid the reintroduction of this disease. Occasional malaria cases are reported among visitors of the Atlantic Forest area of Brazil, while data on residents of this area are scarce. METHODS: A sectional study was carried out to examine 324 individuals living in a municipality where autochthonous cases were detected. RESULTS: Asymptomatic Plasmodium infections were detected in 2.8% of the individuals by polymerase chain reaction (PCR), with one case of P. falciparum (0.3%), two cases of P. vivax (0.6%), and six cases of P. malariae (1.9%). The thick blood smears were negative in all individuals. Serological tests performed in 314 subjects were reactive in 11.1%, with 3.5% for P. falciparum and 7.7% for P. vivax. A subsample of 42 reactive individuals for any Plasmodium species showed P. malariae in 30.9% of specimens. Individuals who entered the Atlantic Forest region were 2.7 times more likely to exhibit reactive serology for P. vivax compared with individuals who did not enter this region (p&lt;0.05). Children &lt;15 years had a higher chance of reactive serology for P. falciparum and P. vivax than individuals ≥15 years of age (p&lt;0.05). Individuals living in the Paraiso district had a higher chance of reactive serology for P. vivax compared to other districts (p&lt;0.05). No associations were found between sex, past exposure to malaria, or serological response to antibodies of any Plasmodium species. CONCLUSIONS: The implications of these results for the elimination of malaria were discussed.

title: Recognition of dynamic and static facial expressions of emotion among older adults with major depression

description: Abstract Introduction The recognition of facial expressions of emotion is essential to living in society. However, individuals with major depression tend to interpret information considered imprecise in a negative light, which can exert a direct effect on their capacity to decode social stimuli. Objective To compare basic facial expression recognition skills during tasks with static and dynamic stimuli in older adults with and without major depression. Methods Older adults were selected through a screening process for psychiatric disorders at a primary care service. Psychiatric evaluations were performed using criteria from the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). Twenty-three adults with a diagnosis of depression and 23 older adults without a psychiatric diagnosis were asked to perform two facial emotion recognition tasks using static and dynamic stimuli. Results Individuals with major depression demonstrated greater accuracy in recognizing sadness (p=0.023) and anger (p=0.024) during the task with static stimuli and less accuracy in recognizing happiness during the task with dynamic stimuli (p=0.020). The impairment was mainly related to the recognition of emotions of lower intensity. Conclusions The performance of older adults with depression in facial expression recognition tasks with static and dynamic stimuli differs from that of older adults without depression, with greater accuracy regarding negative emotions (sadness and anger) and lower accuracy regarding the recognition of happiness.

title: SYNTHESIS, ELECTRONIC AND SPECTRAL PROPERTIES OF NEW 1,3,4-THIADIAZOLE COMPOUNDS AND THE SPECTRAL ANALYSIS OF THEIR CONFORMERS USING DENSITY FUNCTIONAL THEORY

description: In this study, new 1,3,4-thiadiazole compounds were synthesised and characterised by FT-IR, 1H-NMR, UV-vis spectroscopy and elemental analysis, Furthermore, the relationship between the electronic and spectral data of the 16 conformers of each compound was investigated by theoretical calculations; the theoretical data were compared with the experimental results. The B3LYP hybrid functional level with a 6-311++g(2d,2p) basis set was used to obtain the ground state geometries, frontier molecular orbital energies, band gap energies and chemical reactivity parameters and to perform a spectral analysis of the compounds. Significant correlations were calculated between the minimum molecular energy and the N-H and C=O vibrational frequencies and the NH proton chemical shifts of the conformers. The charge density on the nitrogen atom and the delocalisation index of the highly polar N-H covalent bond were investigated by quantum theory of atoms in molecules. The effect of conformer structure on the theoretical results and its role in interpreting the experimental data were presented, and it was theoretically shown that the activity degree of the non-aromatic electronegative atoms or groups of atoms in the intramolecular interaction was a very important factor in determining the electronic and spectral properties of each compound.

title: Management of medical waste in hospitals of Ribeirão Preto (SP), Brazil

description: ABSTRACT This research aimed to evaluate the management of medical waste in hospitals in Ribeirão Preto, São Paulo. This study is characterized as descriptive and exploratory, developed in 11 hospitals in the city. Data collection was carried out through interviews with the medical waste managers, analysis of their management plan and systematized observation. Data collection was initiated after hospital authorization, approval by the CEP of the Escola de Enfermagem de Ribeirão Preto, Universidade de São Paulo. The results revealed that the steps in handling medical waste such as identification, internal transportation, temporary storage, external collection and transport were classified as unsatisfactory, and only segregation was classified as satisfactory. Regarding the type of the treatment offered to medical waste, 7 (63.6%) managers reported that the residues of groups A and E were submitted to microwave treatment; and 5 (45.5%) showed that they did not know about the type of treatment given to group B waste. It is concluded that, despite the existence of a technical-legal framework regulating the guidelines for the managing medical waste, there were inadequacies related to its management.

title: Factors associated with depression symptoms in women after breast cancer

description: ABSTRACT OBJECTIVE: To analyze the factors associated with the presence of depression symptoms in women after breast cancer. METHODS: Cross-sectional study with 181 women with breast cancer, aged 57.0 years (SD = 9.5), who were undergoing treatment or after treatment in the Oncology Research Center in Florianópolis, state of Santa Catarina, Brazil. The questionnaire comprised items addressing general and health information, economic level, anthropometric measures, depression symptoms (Beck Depression Inventory), self-esteem (Rosenberg Self-Esteem Scale), and body image (Body Image After Breast Cancer Questionnaire). Descriptive and inferential statistical analysis were performed by chi-square and Fisher's exact tests to verify association, Mann-Whitney U test to compare the groups and Poisson regression to identify the prevalence ratio of the factors associated with presence of depression symptoms (p &lt; 0.05). RESULTS: We found an association between the presence of depression symptoms and the group of younger women (aged 40–60 years), those who had another disease besides cancer, those who had mastectomy surgery, those who suffered from lymphedema, and those who presented low–medium self-esteem. Less educated women presented more depressive symptoms, as did women with worse body image on the subscales of limitations, transparency, and arm concerns. CONCLUSIONS: Age, educational attainment, diagnosis of other diseases, type of surgery, lymphedema, self-esteem, and body image were factors associated with the presence of depression symptoms in Brazilian women after breast cancer. Health professionals should be aware of these relationships and try to detect depression symptoms earlier and improve the care they provide to these women.

title: Mother Tongue and Communication in the Construction of Mathematical Thinking

description: Abstract This article presents results of a research with the objective of establishing the mother tongue's role in the construction of mathematical thought on a multi-grade group of a rural area. There is a theoretical discussion about communication, the use of the mother tongue and representations in math class; it is also illustrated with respect to the exploratory-research mathematics task. The research followed a qualitative approach, from the perspective of action research. The exploratory-investigative task carried out with the children is described and analyzed, from which it is possible to intuit that math class communication through the mother tongue is a fundamental tool in the concrete, conceptual or symbolic handling of mathematical concepts. It is perceived that children construct meaning from their everyday language, assigning meaning to what they read, hear or represent through oral or written communicative interaction.

title: GOLDEN APPLE CHERRY SNAIL SHELL AS CATALYST FOR HETEROGENEOUS TRANSESTERIFICATION OF BIODIESEL

description: ABSTRACT Calcium oxide catalysts prepared from golden apple cherry snail shell (Pomacea canaliculata) via two steps - deproteination and calcination - were compared: the structure was characterized by XRD and XRF and morphology by SEM. In addition, the effects of reaction time, catalyst loading amount, methanol:oil molar ratio and reaction temperature on the biodiesel yield were measured. The optimum conditions for biodiesel production, 0.8 wt% catalyst loading, 12:1 methanol:oil molar ratio, 65 OC reaction and 6 h reaction time, gave a biodiesel up to 95.2%. Moreover, the catalyst demonstrated high stability, permitting reuse for up to four cycles with biodiesel yield falling by only 4%.

title: Influence of strategic points in the dispersion of Aedes aegypti in infested areas

description: ABSTRACT OBJECTIVE: To evaluate whether sites with large amount of potential breeding sites for immature forms of Aedes aegypti, called strategic points, influence in the active vector's dispersion into properties in their surroundings. METHODS: We selected four areas in the municipality of Campinas, three of them with strategic points classified as high, moderate, and low risk according to infestation and a control area, without strategic points. Between October 2015 and September 2016, we monthly installed oviposition traps and evaluated the infestation by Ae. aegypti in all properties of each selected area. To verify if there was vector dispersion from each strategic point, based on its location, we investigated the formation of clusters with excess of eggs or larvae or pupae containers, using the Gi spatial statistics. RESULTS: The amount of eggs collected in the ovitraps and the number of positive containers for Ae. aegypti did not show clusters of high values concerning its distance from the strategic point. Both presented random distribution not spatially associated with the positioning of strategic points in the area. CONCLUSIONS: Strategic points are not confirmed as responsible for the vector's dispersion for properties in their surroundings. We highlight the importance of reviewing the current strategy of the vector control program in Brazil, seeking a balance from the technical, operational, and economic point of view, without disregarding the role of strategic points as major producers of mosquitoes and their importance in the dissemination of arboviruses in periods of transmission.

title: A randomized, open-label clinical trial comparing the long-term effects of miltefosine and meglumine antimoniate for mucosal leishmaniasis

description: Abstract INTRODUCTION: The treatment of mucosal leishmaniasis (ML) is difficult due to the toxicity and route of administration of standard drugs. Miltefosine is an oral agent used for leishmaniasis treatment; however, no data exist regarding its use for ML in Brazil. In this study, we aimed to evaluate the efficacy of miltefosine for ML treatment compared to that of pentavalent antimonial in a pilot study. METHODS: We performed a randomized clinical trial with two parallel groups. The tested intervention consisted of miltefosine 1.3-2 mg/kg/day (two capsules) for 28 days or intravenous 20 mg SbV/kg/day of meglumine antimoniate (N-MA) for 30 days. The final endpoint was defined as complete healing of the lesion four years after treatment. We also analyzed an early endpoint at 90 days after treatment. RESULTS: Forty patients were included in this study: each experimental group comprised 20 patients. Applying a multivariate model in an intention-to-treat analysis, we observed that patients treated with miltefosine had a cure probability 2.08 times greater (95% confidence interval [CI] = 1.03-4.18) than those treated with N-MA at 90 days after treatment. At the final endpoint, we observed no differences in cure probability between miltefosine and N-MA (relative risk = 0.66; 95% CI = 0.33-1.32). With respect to adverse reactions, significant differences between groups were related to gastrointestinal effects, which were more frequent in the miltefosine group. CONCLUSIONS: Miltefosine may be an interesting alternative for treating ML because of its oral administration and cure rate after long-term follow-up.

title: Factors associated with environmental barriers of people with disabilities in Mexico

description: ABSTRACT OBJECTIVE: To examine the associations between sociodemographic, health and disability-related factors and the perception of environmental barriers outside the home environment by individuals with permanent disabilities in Mexico. METHODS: In this cross-sectional, population-based study, we used data from the 2010 National Survey of Perceptions of Disability in the Mexican Population of 2,041 participants older than 18 with permanent disability. The perceptions of barriers take into consideration the challenges of getting around and using transportation outside the home environment. The covariates consisted of sociodemographic, health-related and disability-related factors. Multivariate logistic regression was used. RESULTS: The perception of environmental barriers outside the home environment was associated with being a woman, living in an urban area, speaking an indigenous language, experiencing emotional symptoms, having walking/movement, visual or self-care disabilities, having severe/extreme disability, having disability caused by illness, using physical devices, and receiving assistance and care in the home environment. CONCLUSIONS: This information is valuable for the design of public policies and programs that promote the participation of individuals with permanent disabilities, a high-priority issue in low- and middle-income countries.
