title: Delirium in elderly inpatients in emergency units: a prospective study

description: ABSTRACT Objectives To determine the incidence of delirium in the elderly admitted to a tertiary hospital and to verify its distribution according to predictor variables. Methods Elderly patients admitted to the emergency room from April to September 2018 were included. The sample was characterized and the difference in the incidence of delirium within five days if hospitalization regarding the predictor variables was observed (Chi-square test, 5%). Results The sample consisted of 300 predominantly male participants (52%), aged 60-69 years (50.7%), eutrophic (49.3%) and with three or more pre-hospitalization diseases (42%). The incidence of delirium was 12% (95% CI 9-16). A statistically significant difference was observed in relation to the number of diseases prior to hospitalization (p = 0.025), the exit from bed during hospitalization (p &lt; 0.001) and the use of bladder tube (p &lt; 0.001). Conclusion The recognition of this disorder is fundamental in the emergency routine of hospitals, where patients with multiple chronic diseases are treated, as delirium commonly underdiagnosed, leading to an increase in morbidity and mortality rates.

title: Depression and quality of life in individuals with Stargardt’s disease

description: ABSTRACT Objectives To assess depression and quality of life in individuals with Stargardt’s disease (SD), macular dystrophy whose central vision loss begins in the first decades of life. Methods This observational, cross-sectional study included 41 SD patients and 46 healthy controls, aged 18 to 63 years old, in Minas Gerais, Brazil. Major depression episode was assessed by the Mini International Neuropsychiatric Interview, depressive symptomatology by the Beck Depression Inventory (BDI) and Hamilton Depression Scale (HAM-D) and quality of life by the National Eye Institute Visual Function Questionnaire. The comparison between sociodemographic variables, quality of life and depression was performed using Fisher’s exact test and Mann-Whitney-Wilcoxon test. Results The prevalence of depression was 12.2% in the sample with SD while in the control group was 8.7% (p = 0.614). No significant differences were observed between patients and the control group regarding the prevalence of depression and sociodemographic variables. Patients with SD had overall lower quality of life scores (59.7 vs. 88.7, p &lt; 0.001), and presented inverse correlation between depressive symptoms, as assessed by BDI (Rho = -0.49, p &lt; 0.001) and by HAM-D (Rho = -0.45, p = 0.003) with quality of life scores. Conclusion Depressive symptoms were the major factors affecting quality of life, regardless of sociodemographic data. Individuals with SD may develop copying strategies, seek mental care to prevent the increase of depression and decrease of quality of life.

title: Birds associated with treefall gaps in a lowland forest in southwestern Brazilian Amazonia

description: ABSTRACT Natural communities are dynamic systems in time and space. The spatial distribution of plants and animals tends to coincide with the availability of resources needed for the survival and reproduction of each species. Natural treefall gaps offer a number of resources that influence the distribution of birds within the forest. We compared the understory bird assemblages of natural treefall gaps (15 sampling points) with those found in the adjacent forest (15 points) in the Humaitá Forest Reserve in southwestern Brazilian Amazonia. We used mist-nets to sample birds and obtained 700 captures of 105 species. Species richness, number of individuals, and species composition were all similar between gaps and forest, although six species presented some degree of association with the gaps, and nine with the forest. Nectarivores preferred gaps significantly over forest, whereas insectivores and frugivores were distributed equally between gaps and forest. Vegetation height and density differed between gaps and forest, and influenced the distribution of bird species in the two environments. Fruit availability was positively correlated with frugivore abundance in gaps. Overall, 33.3% of the birds associated with the treefall gaps are from lower forest canopy, while the others are understory species. We showed that the use of natural gaps by birds in a fragmented landscape of the Amazon forest contributes to the environmental heterogeneity and succession dynamics following natural events of habitat disturbance.

title: Ecological risk assessment of Piper aduncum essential oil in non-target organisms

description: ABSTRACT One possible alternative to chemotherapeutic agents in the treatment and prevention of diseases in fish farms is the use of Piper aduncum essential oil. However, ecotoxicological data are required to ensure its proper use and to prevent adverse effects on non-target organisms. These data are relevant since this essential oil is described as having insecticidal, molluscicidal and cytotoxic activitiy that may be associated with its chemical composition. Thus, the aim of this study was to evaluate the ecotoxicity of P. aduncum essential oil to five test organisms using the species sensitivity distribution (SSD) statistical approach. The chemical composition of the essential oil was characterized by means of gas chromatography coupled to mass spectrometry (GC-MS) and gas chromatography-flame ionization detection (GC-FID) for identification and quantitation purposes, respectively. The main component (75.5%) of the essential oil was dillapiole. The hazardous concentration for 5% of biological species (HC5) was calculated to determine the 95% protection level, resulting in a value of 0.47 mg L-1 (with a confidence interval of 0.028 - 1.19 mg L-1. ). A concentration range related to the level of protection for aquatic communities (the predicted no-effect concentration, PNEC) was determined through the application of safety factors to the HC5 value. The ecotoxicity parameters showed that P. aduncum essential oil can be used safely in water bodies at a concentration equal to or below 0.09 mg L-1.

title: Domestic violence and risk of internalizing and externalizing problems in adolescents living with relatives displaying substance use disorders

description: ABSTRACT Objective To investigate the association between exposure to domestic violence and increased risk of internalizing and externalizing problems and substance use among adolescents living with relatives with substance use disorder (SUD) at a low-income community of São Paulo, Brazil. Methods A cross-sectional study was conducted with 102 adolescents aged 12-17 years (M = 14.2, SD = 1.7) who were living with relatives suffering from SUD. Outcomes were measured using the Youth Self-Report (YSR), psychosocial stress factors questionnaire, Drug Use Screening Inventory (DUSI) and Phrase Inventory of Intrafamily Child Abuse (PIICA). Results The sample presented high prevalence of emotional/behavioral problems with YSR’s scores in the clinical range for Internalizing Problems (24.5%), Externalizing Problems (21.6%), and Total Problems (26.5%). The presence of mental health problems predicted substance use (PR = 2.22; 95% CI = 1.2-4.13), and substance use predicted increased risk of mental health problems. Alcohol use predicted more than double the risk of emotional/behavioral problems (PR = 2.01; 95% CI = 1.08-3.76), while illicit drug use was associated with an almost threefold increase in the prevalence of Internalizing (PR = 2.87; 95% CI = 1.19-6.89) and Externalizing Problems (PR = 3.3; 95% CI = 1.35-8.04). Conclusion Adolescents of relatives with SUD are at risk of developing emotional and behavioral problems. These findings reinforce the need to develop public mental health policies, which include protective interventions to adolescents living in families affected by substance use disorders.

title: Protocol optimization for the detection of Trypanosoma cruzi DNA in açai (Euterpe oleraceae) pulp

description: ABSTRACT Chagas disease, caused by the protozoan Trypanosoma cruzi, has often been linked to oral transmission through açai consumption. Molecular methods that allow fast and accurate identification of the pathogen are important for the detection of the presence of the parasite in this food. This study aimed to optimize polymerase chain reaction (PCR)-based detection of T. cruzi DNA in açai pulp. Several dilutions of T. cruzi DTU TcI trypomastigote forms were cultured in liver infusion tryptose (LIT) medium. Trypanosoma cruzi DNA was extracted from the cells and subjected to PCR. Subsequently, culture dilutions were added to açai pulp to evaluate the detection threshold of the optimized PCR assay. We demonstrate that our assay can detect T. cruzi DNA in açai pulp at a concentration of 1.08 × 10-10 ng µL-1. We conclude that our optimized protocol is effective and can be used as an important tool for the detection of T. cruzi contamination in açaí.

title: Depression, Anxiety, and Stress Scale: psychometric properties and affectivity prevalence

description: ABSTRACT Objective: To estimate psychometric properties of the Depression Anxiety and Stress Scale (DASS-21) among Brazilian university students and to compare the prevalence of depression, anxiety, and stress between men and women. Methods: The DASS-21's fit was evaluated by confirmatory factor analysis using the chi-square per degrees of freedom ratio (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI) and Root Mean Square Error of Approximation (RMSEA). A second-order hierarchical model was tested (Negative Affectivity). The prevalence of depression, anxiety, and stress was calculated and compared by sex. Results: Participants comprised 1,042 university students [aged 18 to 35 years (mean = 21.13; standard deviation = 2.81 years) 65.7% women]. The DASS-21's goodness of fit was adequate (χ2/df = 5.83; CFI = 0.96; TLI = 0.97; RMSEA = 0.07). However, item 2 presented low factorial weight and was excluded (χ2/df = 6.05; CFI = 0.98; TLI = 0.97; RMSEA = 0.07). The study verified that 4.7%, 1.7%, and 4.5% of students presented moderate to extremely severe scores of depression, anxiety, and stress, respectively. There was no significant difference between men and women in the prevalence of the emotional aspects assessed. Conclusion: The DASS-21 demonstrated adequate validity and reliability in a sample of university students. The prevalence of depression, anxiety, and stress did not differ significantly between men and women, which points to the need for an egalitarian view in the investigation of these emotional states.

title: Scorpions (Arachnida, Scorpiones) from the state of Acre, southwestern Brazilian Amazon

description: ABSTRACT Although Brazil has one of the highest scorpion diversities worldwide, the scorpion fauna of the Amazon region remains relatively poorly described. In this study, we updated the list of scorpion species from the state of Acre, in the southwestern Brazilian Amazon, based on a revision of records contained in Brazilian arachnid collections and a survey of the relevant literature. We recorded the occurrence of seven scorpion species belonging to two families (Buthidae and Chactidae) among which we report three new records (Ananteris sp., Tityus (Tityus) gasci, and Chactopsis cf. insignis) for Acre. The results presented herein make an important contribution to the knowledge on scorpion diversity in the Amazonian forests of Acre.

title: Adolescents users of mental health services: assessment of the perception of improvement with treatment Assessment of perceived improvement

description: ABSTRACT Objective To evaluate the change perceived by adolescents, who are users of a specialized outpatient mental health service for children and adolescents. Methods Cross-sectional study with convenience sampling. Individual interviews were conducted with a questionnaire that includes demographic and socioeconomic questions, together with the Perceived Change Scale – patient version, validated in Brazil. This scale addresses perceived changes in several dimensions of life: occupation, physical health, psychobiological aspects, sleep, relationship and emotional stability. The study was conducted from August 2017 to November 2018, covering 100 adolescents between 12 and 18 years undergoing treatment in the service for at least 6 months. Results The majority were female (64.0%), aged between 16 and 18 years (48.0%), attended for more than one year (84.0%). The most cited diagnoses by teenagers were attention deficit hyperactivity disorder (39%) and anxiety disorders (36%). The result of the global evaluation showed the feeling of improvement in 83% of the participants; regarding the perceived change in the items of the scale related to improvement, they include: interest in working (71.0%), coexistence with family (67.0%) and interest in life (60.0%). Conclusion The evaluation of health care offered by public mental health services is an important indicator of quality and resoluteness of actions, making it possible to identify the aspects to be improved or reinforced in work processes, in order to favor better care practices in childhood and adolescence.
