RESUMO
We describe the composition of endoparasites associated with leaf litter anurans from an Atlantic Forest area, in southeastern Brazil. We tested if body size, sex, and reproductive modes of anuran hosts influence endoparasite abundance and richness. We sampled 583 individuals from 11 anuran species and recorded 1,600 helminths from 14 taxa. The helminths that infected the greatest number of anuran host species were the nematodes Cosmocerca parva (8 spp.), Physaloptera sp. (8 spp.), and Cosmocerca brasiliense (7 spp.), and the most abundant helminth species were Physaloptera sp. (14.6%), Cosmocerca brasiliense (13.7%) and Cosmocerca parva (12.6%). Both helminth abundance and richness were positively affected by anuran body size and dependence on water for reproduction. Larger hosts can contain a higher abundance of parasites because they may provide more physical space than smaller ones, or it can simply be a function of age. Besides, parasite species richness can be highly correlated with the amount of time a host spends in association with aquatic habitats, a conservative aspect of both parasite and host natural history. Within host species, there was a positive and significant influence of body size on helminth abundance. Haddadus binotatus females had greater helminth abundance than males, probably due to sex-related differences in behavior and/or in physiology. Our data suggest that reproductive modes could also influence helminth infection parameters in other anuran communities and should be considered in detail in future analyses.

This study isolated and identified autochthonous lactic acid bacteria (LAB) from mandacaru fruit and evaluated their potential probiotic and technological aptitudes in vitro, as well as the protective effects of freeze-dried mandacaru fruit on the most promising LAB isolate during lyophilization and refrigeration storage. Initially, 212 colonies were isolated from mandacaru fruit, and 34 were preliminarily identified as LAB. Thirteen isolates identified by 16S-rRNA sequencing as Pediococcus pentosaceus were negative for DNase, gelatinase, hemolytic, and biogenic amine production. The selected isolates showed proteolytic activity, diacetyl and exopolysaccharide production, and good tolerance to different NaCl concentrations while having low cellular hydrophobicity and antagonistic activity against pathogens. The survival of isolates sharply decreased after 3 h of exposure to pH 2 and had a good tolerance to 1 % bile salt. A principal component analysis selected P. pentosaceus 57 as the most promising isolate based on the examined technological and probiotic-related physiological properties. This isolate was lyophilized with mandacaru fruit and stored under refrigeration for 90 days. P. pentosaceus 57 lyophilized with mandacaru fruit had high viable cell counts (9.69 ± 0.03 log CFU/mL) and >50 % of physiologically active cells at 90 days of refrigeration storage. The results indicate that mandacaru fruit is a source of P. pentosaceus with aptitudes to be explored as potential probiotic and technological characteristics of interest for the food industry, besides being a good candidate for use in lyophilization processes and refrigeration storage of LAB due to its cryoprotective effects.

This study investigated the potential impacts of the flour from Cereus jamacaru cactus cladodes (CJF), a cactus native to the Brazilian Caatinga biome, on the growth and metabolism of different potentially probiotic strains, as well as on the abundance of selected intestinal bacterial populations and microbial metabolic activity during in vitro colonic fermentation with a pooled human fecal inoculum. Cultivation of the probiotics in a medium with C. jamacaru cladodes flour (20 g/L) resulted in viable cell counts of up to 9.8 log CFU/mL, positive prebiotic activity scores (0.73-0.91), decreased pH and sugar contents, and increased lactic, acetic, and propionic acid production over time, indicating enhanced probiotic growth and metabolic activity. CJF overall increased the relative abundance of Lactobacillus spp./Enterococcus spp. (2.12-3.29%) and Bifidobacterium spp. (4.08-4.32%) and decreased the relative abundance of Bacteroides spp./Prevotella spp. (8.35-6.81%), Clostridium histolyticum (6.91-3.59%), and Eubacterium rectale/Clostridium coccoides (7.70-3.95%) during 48 h of an in vitro colonic fermentation using a pooled human fecal inoculum. CJF stimulated the microbial metabolic activity, with decreased pH, sugar consumption, lactic and short-chain fatty acid production, alterations in overall metabolic profiling and phenolic compound contents, and maintenance of high antioxidant capacity during colonic fermentation. These results show that CJF stimulated the growth and metabolic activity of distinct potential probiotics, increased the relative abundance of beneficial intestinal bacterial groups, and stimulated microbial metabolism during in vitro colonic fermentation. Further studies using advanced molecular technologies and in vivo experimental models could forward the investigation of the potential prebiotic properties of CJF.

O objetivo deste artigo foi descrever os aspectos relacionados à segurança alimentar e nutricional entre indivíduos com sobrepeso e obesidade residentes em um território de abrangência de uma Unidade Básica de Saúde de um município do interior da Paraíba. Estudo transversal, descritivo com amostra intencional, realizado em janeiro de 2020 no município de Nova Floresta, Paraíba. Utilizou-se questionário estruturado com dados socioeconômicos; avaliação de segurança alimentar através da Escala Brasileira de Insegurança Alimentar; padrão de consumo; e avaliação antropométrica. Observa-se que a maior parte dos entrevistados eram do sexo feminino, com casa própria quitada, sabendo ler e escrever com facilidade e sem renda fixa. A prevalência foi maior para a insegurança alimentar e seus diferentes níveis, bem como, principalmente entre as mulheres, com mais baixo nível de escolaridade e com excesso de peso. Durante a semana, a maioria dos entrevistados realiza refeições em casa e com outras pessoas, sentado à mesa; ao seu término acham que comeram de forma suficiente. Os alimentos mais consumidos todos os dias ou duas vezes na semana são alimentos básicos da cultura alimentar brasileira. Os entrevistados consomem com menor frequência alimentos processados e ultraprocessados.
overweight and obese individuals residing in a territory covered by a Basic Health Unit in a county in the interior of Paraíba. Cross-sectional, descriptive study with an intentional sample carried out in January 2020 in the county of Nova Floresta, Paraíba. A structured questionnaire with socioeconomic data was used; food security assessment through the Brazilian Food Insecurity Scale; consumption pattern; anthropometric assessment. It is observed that most of the interviewees were female, with their own house paid off, knowing how to read and write easily and without a fixed income. The prevalence was higher for food insecurity and its different levels, as well as, mainly among women, with lower educational level and overweight. During the week, most respondents have meals at home and with other people, sitting at the table; at its end they think they have eaten enough. Every day or twice a week, the most consumed food are basic food of Brazilian food culture. The interviewees less frequently consume processed and ultra-processed food.

Microcapsules of ciriguela peel extracts obtained by ultrasound-assisted extraction were prepared by spray drying, whose results were compared with those of freeze-drying as a control. The effects of spray-drying air temperature, feed flow rate and ratio of encapsulating agents (maltodextrin and arabic gum) were studied. Encapsulation efficiency, moisture content, total phenolic compounds (TPC), water activity, hygroscopicity, solubility, colorimetric parameters, phenolic profile by HPLC/DAD, simulated gastrointestinal digestion and morphology of spray-dried and freeze-dried microcapsules were evaluated, as well as their stability of TPC during 90 days storage at 7 and 25 °C. Spray-dried extract showed higher encapsulation efficiency (98.83%) and TPC (476.82 mg GAE g-1) than freeze-dried extract. The most abundant compounds in the liquid extract of ciriguela peel flour were rutin, epicatechin gallate, chlorogenic acid and quercetin. Rutin and myricetin were the major flavonoids in the spray-dried extract, while quercetin and kaempferol were in the freeze-dried one. The simulated gastrointestinal digestion test of microencapsulated extracts revealed the highest TPC contents after the gastric phase and the lowest one after the intestinal one. Rutin was the most abundant compound after the digestion of both spray-dried (68.74 µg g-1) and freeze-dried (93.98 µg g-1) extracts. Spray-dried microcapsules were of spherical shape, freeze-dried products of irregular structures. Spray-dried microcapsules had higher phenolic compounds contents after 90 days of storage at 7 °C compared to those stored at 25 °C, while the lyophilized ones showed no significant difference between the two storage temperatures. The ciriguela agro-industrial residue can be considered an interesting alternative source of phenolic compounds that could be used, in the form of bioactive compounds-rich powders, as an ingredient in pharmaceutical, cosmetic and food industries.

This study aimed to investigate the effects of spontaneous fermentation on physicochemical characteristics, bioactive compounds, and antioxidant activity of acerola and guava fruit industrial by-products. Viable cell counts of lactic acid bacterial (LAB) in acerola and guava by-products were ≥ 5.0 log CFU/mL from 24 h up to 120 h of fermentation. Fermented acerola and guava by-products had increased luminosity and decreased contrast. Contents of total soluble solids and pH decreased, and titrable acidity increased in acerola and guava by-products during fermentation. Ascorbic acid contents decreased in acerola by-product and increased in guava by-product during fermentation. Different phenolic compounds were found in acerola and guava by-products during fermentation. Fermented acerola and guava by-products had increased contents of total flavonoids, total phenolics, and antioxidant activity. The contents of total flavonoids and total phenolics positively correlated with antioxidant activity in fermented acerola and guava by-products. These results indicate that spontaneous fermentation could be a strategy to improve the contents of bioactive compounds and the antioxidant activity of acerola and guava by-products, adding value and functionalities to these agro-industrial residues.
RESUMO
The objective was to evaluate the effects of the consumption of a mix of baru almond and goat whey on memory performance and anxiety parameters related to the intestinal health of rats treated during aging. The animals were divided into three groups and treated by gavage for 10 weeks (n = 10/each group): Control (CT) - distilled water; Baru almond (BA) - 2000 mg of baru/kg of body weight; and Baru + Whey (BW) - 2000 mg of baru + 2000 mg of goat milk whey/kg of body weight. Anxiety behavior, memory, brain fatty acid profile and fecal microbiota were measured. BA and BW realized less grooming, spent more time in the central area of the open field and the open arms, and realized more head dipping in the elevated plus maze. A higher rate of exploration of the new object in the short and long-term memory was observed in BA and BW. There was an increase in the deposition of MUFAs and PUFAs and oleic acid in the brain of BA and BW. Regarding spatial memory, BA and BW performed better, with an emphasis on BW. There was a beneficial modulation of the fecal microbiota with a reduction of the pathogenic genus Clostridia_UFC-014 in BA and BW and an increase in the abundance of metabolic pathways of interest in the brain-gut axis. Thus, consumption of the mix is efficient in beneficially altering the intestinal microbiota, improving memory and anxiolytic-like behavior in rats during aging.

This systematic review and network meta-analysis aimed to answer the following focused research question: "Does the type of endodontic sealer affect the postoperative pain in patients who received endodontic treatment?" Different databases and grey literature were surveyed. Only one randomized controlled trial were included. The risk of bias in the studies was evaluated by using the Cochrane Collaboration's tool. A random-effects meta-analysis was conducted to compare the risk and intensity of postoperative pain. The quality of the body of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Out of 11,601 studies, 15 remained for qualitative analyses and 12 for meta-analysis. Seven studies were classified at high risk of bias, and 8 studies raised some concerns. No significant differences between the endodontic materials were observed in the direct comparisons, both in risk and in intensity of postoperative pain (pairwise comparisons with 2 studies: I2 = 0%; p > 0.05 and 8 studies: I2 = 23%; p > 0.05, respectively). The certainty of the evidence was graded as low or moderate. There was no difference in the risk and intensity of postoperative pain after filling with different endodontic sealers. Further systematic reviews should be conducted. Trial Registration: PROSPERO Identifier: CRD42020215314.
RESUMO
Renal artery thrombosis is a rare vascular event that precipitates renal infarction. Although in up to one third of cases the etiology is not identified, renal artery lesions, cardioembolism and acquired thrombophilias are the main causes. A bilateral simultaneous idiopathic renal artery thrombosis is an unlikely coincidence. We present two cases of patients with acute bilateral renal artery thrombosis of unknown etiology. Cardiac embolism, acquired thrombophilia and occult neoplasm workups were negative. Both cases were temporarily hemodialysis-dependent and partially recovered renal function under conservative approach with systemic anticoagulation. Recommendations on optimal treatment for renal artery thrombosis are still lacking. We discuss the available options.
RESUMO
BACKGROUND: In acute coronary syndromes (ACS), the optimal revascularization strategy for unprotected left main coronary artery (ULMCA) culprit lesion has been under-investigated. Therefore, we compared clinical characteristics and short- and medium-term outcomes of percutaneous and surgical revascularization in ACS. METHODS AND RESULTS: Of 31886 patients enrolled in a multicenter, national, prospective registry study between October 2010 and December 2020, 246 (0.8%) had ULMCA as a culprit lesion and underwent percutaneous coronary intervention (PCI) alone (n=133, 54%) or coronary artery bypass grafting (CABG) alone (n=113, 46%). Patients undergoing PCI presented more frequently ongoing chest pain (68% versus 41%, p<0.001) and cardiogenic shock (25% versus 1%, p<0.001). Time from admission to revascularization was higher in surgical group with a median time to CABG of 4.5 days compared to 0 days to PCI (p<0.001). Angiographic success rate was 93.2% in patients who underwent PCI. Primary endpoint (all-cause death, non-fatal reinfarction and/or non-fatal stroke during hospitalization) occurred in 15.9% of patients and was more frequent in the PCI group (p<0.001). After adjustment, surgical revascularization was associated with better in-hospital prognosis (odds ratio (OR) 0.164; 95% confidence interval (CI), 0.04-0.64; p=0.009). Similar results were achieved after propensity score matching. No difference was found at one-year all-cause death. CONCLUSION: Percutaneous coronary intervention was the most common revascularization strategy in the ACS with ULMCA culprit lesion. PCI was preferred in unstable patients and presented a high angiographic success. CABG was often delayed and preferred in low-risk patients. At one-year follow-up, PCI and CABG conferred a similar prognosis. The two approaches appear complementary in this high risk cohort.

BACKGROUND: Sporotrichosis is a subcutaneous or implantation mycosis caused by some species of the genus Sporothrix. Rio de Janeiro state, Brazil, experiences hyperendemic levels of zoonotic sporotrichosis, with increasing cases of disseminated disease, especially in people living with HIV (PLHIV). Involvement of the nasal mucosa is rare and occurs isolated or in disseminated cases, with a delayed resolution. METHODOLOGY/PRINCIPAL FINDINGS: This study aimed to describe the epidemiological, clinical, and therapeutic profiles of 37 cases of sporotrichosis with involvement of the nasal mucosa treated at the ear, nose, and throat (ENT) outpatient clinic of the Instituto Nacional de Infectologia Evandro Chagas, Fundação Oswaldo Cruz, from 1998 to 2020. Data were reviewed from the medical records and stored in a database. The Mann-Whitney test was used to compare the means of quantitative variables, and Pearson chi-square and Fisher's exact tests were used to verify the association between qualitative variables (p<0.05). Most patients were males, students or retirees, with a median age of 38 years, residents in the municipality of Rio de Janeiro, and infected through zoonotic transmission. Disseminated sporotrichosis forms in patients with comorbidities (mostly PLHIV) were more common than the isolated involvement of the mucosa. The main characteristics of lesions in the nasal mucosa were the presence/elimination of crusts, involvement of various structures, mixed appearance, and severe intensity. Due to therapeutic difficulty, itraconazole was combined with amphotericin B and/or terbinafine in most cases. Of the 37 patients, 24 (64.9%) healed, with a median of 61 weeks of treatment, 9 lost follow-up, 2 were still treating and 2 died. CONCLUSIONS: Immunosuppression was determinant to the outcome, with worse prognosis and lower probability of cure. Notably in this group, the systematization of the ENT examination for early identification of lesions is recommended to optimize the treatment and outcome of the disease.

During the Zika virus (ZIKV) outbreak and after evidence of its sexual transmission was obtained, concerns arose about the impact of the adverse effects of ZIKV infection on human fertility. In this study, we evaluated the clinical-laboratory aspects and testicular histopathological patterns of pubertal squirrel monkeys (Saimiri collinsi) infected with ZIKV, analyzing the effects at different stages of infection. The susceptibility of S. collinsi to ZIKV infection was confirmed by laboratory tests, which detected viremia (mean 1.63 × 106 RNA copies/µL) and IgM antibody induction. Reduced fecal testosterone levels, severe testicular atrophy and prolonged orchitis were observed throughout the experiment by ultrasound. At 21 dpi, testicular damage associated with ZIKV was confirmed by histopathological and immunohistochemical (IHC) analyses. Tubular retraction, the degeneration and necrosis of somatic and germ cells in the seminiferous tubules, the proliferation of interstitial cells and an inflammatory infiltrate were observed. ZIKV antigen was identified in the same cells where tissue injuries were observed. In conclusion, squirrel monkeys were found to be susceptible to the Asian variant of ZIKV, and this model enabled the identification of multifocal lesions in the seminiferous tubules of the infected group evaluated. These findings may suggest an impact of ZIKV infection on male fertility.

In this study, we evaluated the physical, nutritional, and bioactive properties of mandacaru cladode flour (Cereus jamacaru DC.). The granulometric profile revealed particles with non-uniform geometry, flakiness, a rectangular tendency, and a non-homogeneous surface, with particle sizes ranging from 20 to 60 µm. The flour presented low water activity (0.423), a moisture content of 8.24 g/100 g, high ash (2.82 g/100 g), protein (5.18 g/100 g), and total carbohydrate contents (74.48 g/100 g), and low lipid contents (1.88 g/100 g). Mandacaru flour is an excellent source of insoluble dietary fiber (48.08 g/100 g), calcium (76.33%), magnesium (15.21%), and potassium (5.94%). Notably, 1H NMR analysis revealed the presence of N-methyltyramine. Using HPLC chromatography, glucose was identified as the predominant sugar (1.33 g/100 g), followed by four organic acids, especially malic acid (9.41 g/100 g) and citric acid (3.96 g/100 g). Eighteen phenolic compounds were detected, with relevant amounts of kaempferol (99.40 mg/100 g), myricetin (72.30 mg/100 g), and resveratrol (17.84 mg/100 g). The total phenolic compounds and flavonoids were 1285.47 mg GAE/100 g and 15.19 mg CE/100 g, respectively. The mean in vitro antioxidant activity values were higher using the FRAP method (249.45 µmol Trolox TEAC/100 g) compared to the ABTSâ¢+ method (0.39 µmol Trolox TEAC/g). Finally, the ascorbic acid had a content of 35.22 mg/100 g. The results demonstrate the value of mandacaru as a little-explored species and an excellent matrix for the development of flours presenting good nutritional value and bioactive constituents with excellent antioxidant potential.
RESUMO
Adverse drug events (ADEs) are harmful events caused by medication, and some of which can lead to death. Death records are an important source of information when using codes from the 10th revision of the International Classification of Diseases (ICD-10) suggestive of ADE. This study aimed to identify the ADEs registered in Brazililian Mortality Information System (SIM), analyzing data distribution by year, age group, and type of event. This is an ecological study with retrospective data collection, identifying ADEs in the SIM, using the ICD-10 codes. The study included deaths that occurred in Brazil from 2008 to 2016. An increase in the number of deaths associated with ADE was observed from 2008 to 2016, with a mortality rate per 1 million inhabitants ranging from 8.70 to 14.40 in the period. Most events corresponded to mental and behavioral disorders due to the use of psychotropic drugs. Most deaths (12,311) related to ADE codes were identified in several chapters of the ICD-10. Chapter XX, about adverse events, allowed the identification of a smaller number of deaths (4,893). Higher event rates were observed among individuals aged 60 years and over (39.8/1 million) and children younger than one year (22.0/1 million). The identification of ADE-related deaths on the SIM is an important strategy for addressing undesirable drug-related events. Deaths related to the use of psychotropic drugs were the most frequent ADE-related deaths and the elderly were the age group most affected by ADEs.
Os eventos adversos a medicamentos (EAM) são danos aos pacientes relacionados ao uso de medicamentos, parte dos quais pode levar à morte. Os registros de óbitos são fonte importante de informação, quando se empregam os códigos da 10ª revisão da Classificação Internacional de Doenças (CID-10) sugestivos de EAM. O estudo identificou os EAM registrados no Sistema de Informação sobre Mortalidade (SIM), analisando sua distribuição por ano, faixa etária e tipo de evento. Trata-se de um estudo ecológico com coleta de dados retrospectiva de identificação de EAM no SIM, por meio dos códigos da CID-10. O estudo compreendeu óbitos ocorridos no Brasil, de 2008 a 2016. Houve aumento nas proporções de óbitos associados aos EAM de 2008 a 2016, com taxa de mortalidade por 1 milhão de habitantes indo de 8,70 para 14,40 no período. A maioria dos eventos correspondeu aos transtornos mentais e comportamentais em razão do uso de psicofármacos. A maioria dos óbitos (12.311) relacionados a códigos de EAM foram identificados em diversos capítulos da CID-10. Já o capítulo XX, específico para eventos adversos, permitiu identificar parcela menor de óbitos (4.893). As maiores taxas de eventos ocorreram entre indivíduos com 60 anos ou mais (39,8/1 milhão) e crianças menores de um ano (22,0/1 milhão). A identificação de óbitos associados aos EAM, por meio do SIM, constitui uma estratégia importante para a abordagem dos eventos indesejáveis relacionados aos medicamentos. Os óbitos relacionados ao uso de psicofármacos foram os de maior frequência e os idosos foram a faixa etária mais acometida por EAM.

OBJECTIVES: This study aims to investigate the compliance of randomized controlled trials (RCTs) in posterior restorations with the Consolidated Standards of Reporting Trials Statement (CONSORT) statement and to analyze the risk of bias (RoB) of these studies. METHODS: A systematic search was performed in PubMed, Scopus, Web of Science, LILACS/BBO, and Cochrane Library. Only RCTs published in peer-reviewed journals were included. The compliance with the CONSORT was evaluated in a 0-2 scale where 0 = no description, 1 = poor description and 2 = adequate description. Descriptive analyses of the CONSORT mean score by journal, country, and RoB were performed. The RoB in RCTs was evaluated by using the Cochrane Collaboration's tool version 1.0. RESULTS: A total of 15,476 studies were identified after duplicates removal. O only 202 meet the eligibility criteria, among which 31 were follow-up studies. Concerning the overall RoB, only 29 out of 171 were classified as low risk of bias. The overall mean CONSORT score was 19 ± 5.4 points, which means compliance of approximately 59%. Significant differences among countries, publication period, and RoB were observed (p < 0.001). The journal's impact factor was not correlated with the overall CONSORT score (p = 0.36). CONCLUSIONS: The adherence of RCTs conducted in posterior restorations to the CONSORT Statement is still low. In addition, most studies were classified as at unclear risk of bias. These results call up an urgent need for improvement. CLINICAL RELEVANCE: Most RCTs conducted in posterior teeth have poor reporting and are mainly classified as having an unclear risk of bias.

BACKGROUND: Cutaneous leishmaniasis results from complex interactions between human beings, vectors and the environment. Parasitic species differ in epidemiological and geographical contexts. METHODS: We studied a retrospective cohort of 696 patients with cutaneous leishmaniasis treated at a reference centre in the state of Rio de Janeiro, Brazil, between 2000 and 2015. We analysed displacements due to work, leisure and migrations with identification of Leishmania species. RESULTS: The geographic distribution of autochthonous cases showed that >95% of infections occurred in urban areas. In the state of Rio de Janeiro, most cases were concentrated in the cities surrounding forest parks and nature conservation areas. The same applies to the city of Rio de Janeiro, where these infections occurred in the neighbourhoods surrounding some mountain and forest areas. The non-displacement group included 575 (82.6%) patients and the displacement group included 121 (17.4%) patients. Leishmania (Viannia) braziliensis predominated in both groups. Other species were found in the displacement group. CONCLUSIONS: The disordered urbanization of the state of Rio de Janeiro in recent decades has created conditions for the emergence of urban foci of transmission close to forest areas. Changes in the environment, movement of infected individuals and adaptation of sandflies may have contributed to this.

BACKGROUND: Treatment of cutaneous leishmaniasis (CL) remains challenging since the drugs currently used are quite toxic, thus contributing to lethality unrelated to the disease itself but to adverse events (AE). The main objective was to evaluate different treatment regimens with meglumine antimoniate (MA), in a reference center in Rio de Janeiro, Brazil. METHODOLOGY: A historical cohort of 592 patients that underwent physical and laboratory examination were enrolled between 2000 and 2017. The outcome measures of effectiveness were epithelialization and complete healing of cutaneous lesions. AE were graded using a standardized scale. Three groups were evaluated: Standard regimen (SR): intramuscular (IM) MA 10-20 mg Sb5+/kg/day during 20 days (n = 46); Alternative regimen (AR): IM MA 5 mg Sb5+/kg/day during 30 days (n = 456); Intralesional route (IL): MA infiltration in the lesion(s) through subcutaneous injections (n = 90). Statistical analysis was performed through Fisher exact and Pearson Chi-square tests, Kruskal-Wallis, Kaplan-Meier and log-rank tests. RESULTS: SR, AR and IL showed efficacy of 95.3%, 84.3% and 75.9%, with abandonment rate of 6.5%, 2.4% and 3.4%, respectively. IL patients had more comorbidities (58.9%; p = 0.001), were mostly over 50 years of age (55.6%), and had an evolution time longer than 2 months (65.6%; p = 0.02). Time for epithelialization and complete healing were similar in IL and IM MA groups (p = 0.9 and p = 0.5; respectively). Total AE and moderate to severe AE that frequently led to treatment interruption were more common in SR group, while AR and IL showed less toxicity. CONCLUSIONS/SIGNIFICANCE: AR and IL showed less toxicity and may be good options especially in CL cases with comorbidities, although SR treatment was more effective. IL treatment was an effective and safe strategy, and it may be used as first therapy option as well as a rescue scheme in patients initially treated with other drugs.

Introdução: o sono é essencial à sobrevivência e sua função principal é a restauração física e mental. Objetivo:avaliar a qualidade do sono em alunos de graduação matriculados em cursos de diferentes áreas daUniversidade Federal do Ceará Campus Sobral. Métodos: estudo transversal que investigou a qualidade dosono em alunos de Engenharia Elétrica, Odontologia e Música, por meio da aplicação de questionários: Índicede Qualidade do Sono de Pittsburgh e Escala de Sonolência de Epworth. Os dados foram decodificadosno programa Microsoft Office Excel e expressos em frequência absoluta ou relativa no software GraphPadPrism 5. Resultados: a frequência de boa qualidade de sono foi de 32,67%; de qualidade ruim, 45,54%; e21,78% pontuaram em distúrbios do sono. A Engenharia apresentou maior qualidade de sono ruim (54,55%)e distúrbio do sono (27,27%); a Odontologia, 44,93% de qualidade de sono ruim; já no curso de Música, aboa qualidade do sono foi consideravelmente alta (53,97%) em relação aos demais. Os piores índices foramdo início e do meio da graduação, sendo elevados para sonolência diurna excessiva em todos os cursos.Conclusão: acadêmicos, principalmente de Odontologia e Engenharia Elétrica, apresentaram qualidade desono ruim, altas prevalências de distúrbios do sono e sonolência diurna excessiva.(AU)
Introduction: sleep is essential for survival and its main function is physical and mental restoration. Objective: to evaluate the quality of sleep in undergraduate students enrolled in courses in different areas at the Federal University of Ceará - Campus Sobral. Methods: cross-sectional study that investigated sleep quality in electrical engineering, dentistry and music students through the application of questionnaires: Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale. The data were decoded in the Excel Microsoft Office program and expressed in absolute or relative frequency in the GraphPad Prism 5 software. Results: the frequency of good sleep quality was 32.67%; of poor quality, 45.54% and 21.78% scored in sleep disorders. Engineering showed higher quality of bad sleep (54.55%) and sleep disturbance (27.27%); Dentistry, 44.93% of poor sleep quality; in the music course, the good quality of sleep was considerably high (53.97%) in relation to the others. The worst rates were at the beginning and middle of graduation, being elevated for excessive daytime sleepiness in all courses. Conclusion: academics, mainly in Dentistry and Electrical Engineering, had poor sleep quality, high prevalence of sleep disorders and excessive daytime sleepiness.(AU)

BACKGROUND: American tegumentary leishmaniasis (ATL) is a neglected disease with wide territorial distribution. Knowledge is scarce in children and adolescents. This study aims to compare the clinical features and response to antimony treatment in pediatric and adult patients with cutaneous leishmaniasis. METHODS: A retrospective cohort study was performed with 659 patients who attended a reference centre in Rio de Janeiro, Brazil, from 2000 to 2015. The pediatric cohort consisted of 131 (20%) patients and the adult cohort consisted of 528 (80%) patients. RESULTS: The epidemiological profile, antimony therapeutic response and incidence of adverse events (AE) were different in the pediatric cohort compared with the adult cohort. Mucosal form was less frequent in the pediatric cohort (RR:0.49, p=0.011). Lesions in the head, neck and trunk were more frequent in the pediatric cohort (RR:1.49, p=0.043). The effectiveness of antimony treatment was superior in the pediatric cohort (88.3% vs 76.6%) with a shorter healing time (RR:0.49, p=0.009). Pediatric patients had lower proportions of moderate to severe AE compared with adults (RR:0.45, p=0.027). Clinical AE predominated in the adult cohort (RR:0.40, p=0.000) and laboratory AE in the pediatric cohort (RR:1.50, p=0.023). CONCLUSIONS: This study adds to the body of knowledge on differences that exist between different age groups in ATL.
