title: Screening for Alzheimer's disease in low-educated or illiterate older adults in Brazil: a systematic review

description: ABSTRACT Cognitive screening instruments are influenced by education and/or culture. In Brazil, as illiteracy and low education rates are high, it is necessary to identify the screening tools with the highest diagnostic accuracy for Alzheimer's disease (AD). Objective: To identify the cognitive screening instruments applied in the Brazilian population with greater accuracy, to detect AD in individuals with a low educational level or who are illiterate. Methods: Systematic search in SciELO, PubMed and LILACS databases of studies that used cognitive screening tests to detect AD in older Brazilian adults with low or no education. Results: We found 328 articles and nine met the inclusion criteria. The identified instruments showed adequate or high diagnostic accuracy. Conclusion: For valid cognitive screening it is important to consider sociocultural and educational factors in the interpretation of results. The construction of specific instruments for the low educated or illiterate elderly should better reflect the difficulties of the Brazilian elderly in different regions of the country.

title: Fetal death: obstetric, placental and fetal necroscopic factors

description: ABSTRACT Introduction: Fetal death is defined as the death of the product of conception, regardless of gestational age. Objectives: The objective of this study was to investigate the maternal (obstetrical and placental) risk factors and the necropsy findings associated with fetal death, based on data obtained from the Verification of Death Service [Serviço de Verificação de Óbito (SVO)] in Florianópolis, Santa Catarina, Brazil. Material and method: This is an observational, cross-sectional study using secondary data. Were included the reports released between 2010 and 2015, with a diagnosis of fetal deaths at gestational age of 20 weeks or more. Results: During the period evaluated, 210 autopsies were performed. From these, 15.2% (n = 32) presented umbilical cord abnormalities, 22.4% (n = 47) placental abnormalities, 49.5%(n = 104) maternal health problem related to pregnancy, and 10% (n = 21) previous maternal disease. Among the fetal characteristics involved, it was observed that 6.7% (n = 14) presented meconium aspiration and 5.2% (n = 11) fetal malformations. In this study, 21.9%(n = 46) did not have their causa mortis defined. Discussion: The findings of this study show a statistically significant association (p &lt;0.05) between meconium aspiration and full term pregnancy, hospital origin and normal birth weight. Such information is in agreement with the literature, which shows signs of intrauterine hypoxia, such as the presence of meconium, which are more prevalent in full term pregnancy. Conclusion: Among the causes of fetal death, ascending infection was the most prevalent; the maternal death related to pregnancy were the ones that stood out the most.

title: Winged ants (Hymenoptera: Formicidae) presence in twigs on the leaf litter of Atlantic Forest

description: Abstract: In the leaf litter, ants have various nesting resources available, such as live or dead trunks, twigs, leaves, fruits and seeds. On the twigs, there are adults and immature individuals, but also the queen and winged. The production of wings requires time and energy from the colony. The objective of this study was to investigate the presence of winged in ant colonies in twigs on the leaf litter. Our prediction is that the richness and abundance of winged in twigs are the greatest in rainy months. We collected all twigs with ants in 552 plots with 16 m2, totaling 8,832 m2 of leaf litter, in areas located in the Brazilian Atlantic Domain. We compared the species richness and the number of colonies with and without winged, as well as the number of winged over a year. In total, we collected 1,521 twigs with colonies belonging to 92 species of ants. The rate of twigs with winged was low, about 12%. In colonies with winged, the total number of twigs, species and amount of winged does not differ between the months considered dry and rainy. The majority of winged species are leaf litter dwellers, such as Linepithema neotropicum, recorded with the highest amount of winged irrespective of the period. Arboreal species colonized 15% of the twigs and, in 1/3 of these species, winged were recorded as part of the composition of the colony. Although winged represent a small percentage of the colony in twigs, our results indicate that this feature is important for the life cycle of 44% of the species that occupy twigs, considering that winged are fundamental for the dispersion of the colony.

title: Endophthalmitis after cataract surgery: results from seven years of epidemiological surveillance

description: Abstract Purpose: This study aims to describe the incidence, clinical presentation, and evolution of endophthalmitis cases occurred at an ophthalmologic center in Brazil. Methods: This is a review of medical records of patients undergoing cataract surgery from 2008 to 2014. Clinical variables associated with the outcome of postoperative endophthalmitis were evaluated. Results: during the study period, 27,609 cataract surgeries were performed. It was identified 35 cases of endophthalmitis. The overall incidence of endophthalmitis was 0.13%, with an annual variation from 0.04% to 0.27%. The main signs and symptoms in patients with endophthalmitis were ocular pain and low visual acuity associated with conjunctival hyperemia and hypopyon. Gram-positive microorganisms were the most frequent etiological agents. All patients received an intra-vitreous injection of antibiotics as immediate treatment. The final visual acuity was equal to or worse than the ability to count the examiner's fingers in 57.1% of the patients. Evisceration or enucleation was required in 3 patients. Conclusion: The incidence of endophthalmitis and the majority of signs and symptoms found in this study were in agreement with literature in the field. Although the incidence rate is low, the loss of vision experienced by most patients with endophthalmitis after cataract surgery highlights the need for efforts to prevent infection and early diagnosis to avoid such complications.

title: Butterflies (Lepidoptera: Papilionoidea) from the campos rupestres of Serra de São José, Minas Gerais, Brazil

description: Abstract We provide the first inventory of butterfly species (Lepidoptera: Papilionoidea) in Serra de São José, Minas Gerais, Brazil. Serra de São José has elevations ranging from 800 m to 1,400 m above sea level; the butterflies were sampled using traps and entomological nets in seven plots along the altitudinal gradient. We recorded 647 butterflies belonging to 112 species and six families. We also recorded one threatened species and three endemic species for the Cerrado domain, which suggests that Serra de São José is an important refuge for butterfly conservation.

title: Child protagonism: a study in the context of institutions dedicated to early childhood education in Bologna

description: ABSTRACT In this article, our objective is to consider some ways in which the protagonism of children linked to early childhood education has been enhanced through the spaces available to them, and the teaching activity in which they are integrated. As such, educational institutions in the city of Bologna (Italy) that exclusively attend small children were the subjects of observation. In addition, some materials publicizing their pedagogical proposals were consulted. Analytically, we particularly operate with the concepts of an Everyday Life (OLIVEIRA-FORMOSINHO et al., 2007; BARBOSA, 2010; CARVALHO e FOCHI, 2016; 2017). The results indicated that, in the observed schools, both spacial organization and teacher performance encourage the construction of autonomy and independence in the children, i.e., they are the main protagonists of their own development and learning processes.

title: HLA-alleles class I and II associated with genetic susceptibility to neuromyelitis optica in Brazilian patients

description: ABSTRACT Objective: To study the genetic susceptibility to neuromyelitis optica (NMO) as well as the relationship between HLA genotypes and susceptibility to the disease in the southern Brazilian population. Methods: We analyzed patients with NMO, who met criteria for Wingerchuk's diagnosis of NMO, with detected serum anti-AQP4-IgG antibody. The HLA genotyping was performed by high-resolution techniques (Sanger sequencing) in patients and controls. The HLA genotypes were statistically compared with a paired control population. Results: The HLA genotyping revealed the diversity of the southern Brazilian population whose HLA profile resembled European and Asian populations. Some alleles had statistical correlations with a positive association (increased susceptibility) with NMO, particularly the HLA-DRB1*04:05 and *16:02. Conclusions: In our study, the HLA genotype was different to that previously reported for other Brazilian populations. Although our study had a small cohort, HLA genotypes were associated with increased susceptibility to NMO for HLA-DRB1*04:05 and *16:02. The alleles of HLA class I HLA-A*02:08 and *30:09, HLA-B*08:04 and *35:04 showed an association before the Bonferroni correction.

title: Gamma knife radiosurgery for trigeminal neuralgia: first case series from Latin America

description: ABSTRACT Gamma Knife® radiosurgery (GKRS) for trigeminal neuralgia is an effective treatment with at least a 50% reduction of pain in 75-95% of patients. Objective: To present the first series of patients treated for trigeminal neuralgia using GKRS in Latin America. Methods: Retrospective analysis. Analysis consisted of time to improvement of symptoms, best Barrow Neurological Institute scale (BNI) score after procedure, time without pain, time to recurrence and post-procedural hypoesthesia. Results: Nineteen cases of classical trigeminal neuralgia were analyzed and three cases of symptomatic trigeminal neuralgia were described. Mean time from symptom onset to radiosurgery was 99.6 months, and 78.9% of patients had undergone invasive procedures before treatment. Patients were followed for a mean of 21.7 months. BNI I was achieved in 36.8%, IIIa in 21.1%, IIIb in 21.1%, IV in 5.3% and V in 15.7%. New hypoesthesia developed in 12.1% patients, which was associated with achieving BNI I after the procedure (p &lt; 0.05). Time from diagnosis to GKRS was higher in patients who failed to achieve BNI I (143 vs. 76 months). The distance from the root entry zone in patients who achieved BNI I was greater than patients who did not (1.94 vs. 1.14 mm). Mean distance from the root entry zone in patients with new hypoesthesia was 2.85 mm vs. 1.06 mm (p = 0.06). Conclusion: Clinical response to GKRS is related to the time between diagnosis and procedure, thus its indication should be considered early in the management of these patients.
