Spatio-temporal six-year retrospective study on dermatophytosis in Rio de Janeiro, Southeast Brazil: A tropical tourist locality tale.

Trichophyton, Microsporum, Nannizzia and Epidermophyton genera cause dermatophytosis, the most common and highly contagious infectious skin disease. Rio de Janeiro is one of the most visited cities in the Southern Hemisphere, located in the most visited state of Brazil. This retrospective study investigated epidemiological and laboratorial aspects of dermatophytosis in Rio de Janeiro state, Brazil, by using spatiotemporal analysis. More than half of all individuals were infected by one or more dermatophytes. A variation between 18 and 106 years-old of the studied population was verified, and women more frequently affected. Patients were more frequently infected by Trichophyton spp., most of them T. rubrum, followed by T. mentagrophytes. M. canis and N. gypsea were more frequently isolated in the age group between 40 and 60 years old, while T. rubrum predominates among younger patients. All species presented homogeneous distribution while T. tonsurans appears to be restricted to the Rio de Janeiro capital and E. floccosum to the municipality of Macaé (190 Km apart from RJ). Rio de Janeiro state presented spatial clusters of dermatophytosis with high density in Guanabara Bay (E. floccosum, M. canis, N. gypsea, T. tonsurans) and Niterói (T. rubrum, T. mentagrophytes) but low density in Macaé (E. floccosum). Significant spatiotemporal clusters on dermatophytosis cases were detected in distinct municipalities (p-value ≤ 0.05). The Vulnerability Index (r = 0.293) and Demographic Density (r = 0.652) distributed according to neighborhoods in Niterói were direct related with dermatophytosis cases whereas Income (r = -0.306) was inversely correlated (p-value ≤ 0.05). The dermatophytosis spatiotemporal distinct distribution after two major international events in Rio de Janeiro, Brazil, highlight the pressing need for specific measures of its prevention and controlling. This is particularly relevant in touristic tropical localities which must consider both socio-economical and traveler's medicine variables.

Antimalarials and amphotericin B interact synergistically and are new options to treat cryptococcosis.

Cryptococcus gattii and Cryptococcus neoformans are the main etiological agents of cryptococcosis, an invasive mycosis treated with amphotericin B, 5-fluorocytosine, and fluconazole. This limited arsenal is toxic and is associated with antifungal resistance. Cryptococcosis and malaria pathogens are eukaryotic organisms that have a high incidence in Sub-Saharan Africa. The antimalarials (ATMs) halofantrine (HAL) and amodiaquine (AQ) block Plasmodium heme polymerase, and artesunate (ART) induces oxidative stress. Considering that Cryptococcus spp. is susceptible to reactive oxygen species and that iron is essential for metabolism, the repurposing of ATMs for treating cryptococcosis was tested. ATMs reduced fungal growth, induced oxidative and nitrosative stresses, and altered ergosterol content, melanin production, and polysaccharide capsule size in C. neoformans and C. gattii, revealing a dynamic effect on fungal physiology. A comprehensive chemical-genetic analysis using two mutant libraries demonstrated that the deletion of genes involved in synthesizing components of the plasma membrane and cell wall, and oxidative stress responses are essential for fungal susceptibility to ATMs. Interestingly, the amphotericin B (AMB) fungicidal concentrations were ∼10 times lower when combined with ATMs, demonstrating a synergistic interaction. Further, the combinations showed reduced toxicity to murine macrophages. Finally, HAL+AMB and AQ+AMB efficiently reduced lethality and fungal burden in the lungs and brain in murine cryptococcosis. These findings provide perspectives for further studies with ATMs against cryptococcosis and other fungal infections.

Diversity of rhizobia, symbiotic effectiveness, and potential of inoculation in Acacia mearnsii seedling production.

Black wattle (Acacia mearnsii) is a forest species of significant economic importance in southern Brazil; as a legume, it forms symbiotic associations with rhizobia, fixing atmospheric nitrogen. Nonetheless, little is known about native rhizobia in soils where the species is cultivated. Therefore, this study aimed to evaluate the diversity and symbiotic efficiency of rhizobia nodulating A. mearnsii in commercial planting areas and validate the efficiency of a potential strain in promoting seedling development. To this end, nodules were collected from four A. mearnsii commercial plantations located in Rio Grande do Sul State, southern Brazil. A total of 80 rhizobia isolates were obtained from black wattle nodules, and thirteen clusters were obtained by rep-PCR. Higher genetic diversity was found within the rhizobial populations from the Duas Figueiras (H' = 2.224) and Seival (H' = 2.112) plantations. Twelve isolates were evaluated belonging to the genus Bradyrhizobium, especially to the species Bradyrhizobium guangdongense. The principal component analysis indicated an association between rhizobia diversity and the content of clay, Ca, Mg, and K. Isolates and reference strains (SEMIA 6163 and 6164) induced nodulation and fixed N via symbiosis with black wattle plants after 60 days of germination. The isolates DF2.4, DF2.3, DF3.3, SEMIA 6164, SEMIA 6163, CA4.3, OV3.4, and OV1.4 showed shoot nitrogen accumulation values similar to the N + control treatment. In the second experiment (under nursery conditions), inoculation with the reference strain SEMIA 6164 generally improved the growth of A. mearnsii seedlings, reinforcing its efficiency even under production conditions.

Genetic diversity, phylogenetic and phylogeographic analyses of Oncideres impluviata (Germar, 1823) (Coleoptera: Cerambycidae) in Rio Grande do Sul state, Brazil

ABSTRACT The Cerambycidae Oncideres impluviata (Germar, 1823) is an important insect pest for Acacia mearnsii De Wild in Southern Brazil. The damage caused by their girdling behavior reduces tree productivity, specially in the early years of plant establishment, when girdling is performed on the main trunk of trees. Here, we used a fragment of the mtDNA COI gene to analyze the genetic diversity, population structure and demography of O. impluviata in Southern Brazil, as well as to present the first hypothesis of phylogenetic relationships among species of the genus Oncideres. Our results identified five distinct haplotypes among the populations of O. impluviata, with the most common haplotype identified as O.imp_COI_01. The phylogenetic inferences corroborated the monophyly of O. impluviata with maximum statistical support. In addition, the phylogeny recovered three main population strains that are largely congruent with the haplotype network, which includes two lineages that are found in different edaphic regions of Rio Grande do Sul (Serra do Sudeste and Encosta Inferior do Nordeste). This is the first molecular phylogenetic assessment of O. impluviata. Our findings provide insights into the evolution of a significant species for the Brazilian forestry sector, as well as new resources for planning of pest management strategies.

Influence of Geographical Location on Access to Reperfusion Therapies and Mortality of Patients with STEMI in Sergipe: VICTIM Register. / Influência da Localização Geográfica no Acesso às Terapias de Reperfusão e Mortalidade de Pacientes com IAMcSST em Sergipe: Registro VICTIM.

BACKGROUND: The concentration of high-complexity services in Aracaju, Sergipe can impose certain disparity in the quality of care for the patients with ST-segment elevation acute myocardial infarction (STEMI) (STEMI) who receive care from Brazil's Unified Health System (SUS, acronym in Portuguese) and whose symptoms started in other health regions of the state. OBJECTIVE: To evaluate disparities in access to reperfusion therapies and 30-day mortality, among patients with STEMI, who were users of SUS, in each of the 7 health regions of Sergipe. METHODS: A total of 844 patients with STEMI in the period from 2014 to 2018, assisted by the only hospital with the capacity to offer primary percutaneous coronary intervention (PPCI) to SUS users in the state of Sergipe, were evaluated. The patients were divided into 7 groups according to the location at the onset of symptoms, following the existing division of health regions in the state. For comparison between groups, a significant difference was considered when p < 0.05. RESULTS: Of the total of 844 patients suffering from STEMI who were transferred to the hospital with PPCI that serves SUS patients, 386 patients (45.8%) underwent primary angioplasty. The mean rate of fibrinolytic use was 2.6%, with no differences between the regions. The mean total time of arrival to the hospital with PPCI was 21 hours and 55 minutes, with a median of 10 hours and 22 minutes (6 hours and 30 minutes to 22 hours and 52 minutes). Total 30-day mortality was 12.8%, but without differences between the regions, even when adjusted for age and sex. CONCLUSIONS: This study reveals that fibrinolytics are underused throughout the state and that there is a significant delay in access to the hospital with PPCI, in all health regions of Sergipe.

FUNDAMENTO: A concentração de serviços de alta complexidade em Aracaju/SE pode proporcionar disparidade na qualidade assistencial para os pacientes do SUS com infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMcSST) cujos sintomas se iniciaram em outras regiões de saúde do estado. OBJETIVO: Avaliar disparidades no acesso às terapias de reperfusão e mortalidade em 30 dias, entre pacientes com IAMcSST, usuários do SUS, em cada uma das 7 regiões de saúde em Sergipe. MÉTODOS: Foram avaliados 844 pacientes com IAMcSST no período de 2014 a 2018 atendidos pelo único hospital com capacidade de ofertar intervenção coronariana percutânea (ICP) primária para usuários do SUS no estado de Sergipe. Os pacientes foram divididos em 7 grupos de acordo com o local de início dos sintomas e obedecendo a divisão já existente das regiões de saúde do Estado. Para comparação entre grupos, foi considerada diferença significativa quando p < 0,05. RESULTADOS: Do total de 844 pacientes vítimas de IAMcSST e transferidos ao hospital com ICP que atende pacientes do SUS, 386 pacientes (45,8%) realizaram angioplastia primária. A taxa média do uso de fibrinolítico foi de 2,6%, não havendo diferenças entre as regiões. O tempo médio total de chegada ao hospital com ICP foi de 21h55' com mediana de 10h22' (6h30' ­ 22h52'). A mortalidade total em 30 dias foi 12,8%, mas sem diferenças entre as regiões, mesmo quando ajustada para idade e sexo. CONCLUSÕES: Este estudo revela que os fibrinolíticos são subutilizados em todo o estado e que existe um atraso significativo no acesso ao hospital com ICP, em todas as regiões de saúde de Sergipe.

Access to Reperfusion Therapy and Mortality in Women with ST-Segment-Elevation Myocardial Infarction: VICTIM Register. / Acesso à Terapia de Reperfusão e Mortalidade em Mulheres com Infarto Agudo do Miocárdio com Supradesnivelamento do Segmento ST: Registro VICTIM.

BACKGROUND: Myocardial reperfusion is a fundamental part of the treatment for ST elevation myocardial infarction (STEMI) and is responsible for reducing morbidity and mortality in affected patients. However, reperfusion rates are usually lower and mortality rates higher in women compared to men. OBJECTIVES: To evaluate the prevalence of the use of reperfusion therapies among women and men with STEMI in hospitals where percutaneous coronary intervention (PCI) is available in the state of Sergipe. METHODS: This is a cross-sectional study that used data from the VICTIM Register. Patients diagnosed with STEMI admitted to the four hospitals (one public and three private) where PCI is available in the state of Sergipe were evaluated, from December 2014 to June 2018. A multivariate analysis with adjusted model using mortality as a dependent variable was made. In all analyses, the level of significance adopted was 5% (p < 0.05). RESULTS: A total of 878 volunteers with a confirmed diagnosis of STEMI, of which 33.4% were women, were included in the study. Only 53.3% of the patients underwent myocardial reperfusion (134 women versus 334 men). Fibrinolysis was performed only in 2.3% of all patients (1.7% of women versus 2.6% of men; p = 0.422). The rate of primary PCI was lower (44% versus 54.5%; p = 0.003) and hospital mortality was higher (16.1% versus 6.7%; p < 0.001) in women than in men. CONCLUSION: Women have significantly lower rates of primary PCI and higher hospital mortality. Reperfusion rates were low in both sexes and there was a clear underutilization of thrombolytic agents.

Foi aplicada análise multivariada com modelo ajustado utilizando mortalidade como variável dependente. Em todas as análises, o nível de significância adotado foi de 5% (p<0,05). RESULTADOS: Foram incluídos 878 voluntários com diagnóstico confirmado de IAMCSST, dos quais 33,4% eram mulheres. Apenas 53,3% dos pacientes foram submetidos à reperfusão miocárdica (134 mulheres versus 334 homens). A fibrinólise foi realizada somente em 2,3% de todos os pacientes (1,7% das mulheres versus 2,6% dos homens; p=0,422). Nas mulheres, a taxa de ICP primária foi menor (44% versus 54,5%; p=0,003) e a mortalidade hospitalar foi maior (16,1% versus 6,7%; p<0,001) que nos homens. CONCLUSÃO: As mulheres apresentam taxas significativamente menores de ICP primária e significativamente maiores de mortalidade hospitalar que os homens. A taxa de reperfusão em ambos os gêneros foi baixa e houve nítida subutilização de agentes trombolíticos.

The Therapeutic Value of Hydralazine in Reducing Inflammatory Response, Oxidative Stress, and Mortality in Animal Sepsis: Involvement of the PI3K/AKT Pathway.

ABSTRACT: Sepsis is an amplified systemic immune-inflammatory response produced by a microorganism, which involves activation of inflammatory cytokine signaling pathways and oxidative stress. A variety of studies have shown that hydralazine (HDZ) has potent antioxidant and anti-inflammatory proprieties. Therefore, we hypothesize that HDZ can improve the clinical outcome of sepsis. Thus, this work aimed to evaluate therapeutic value of HDZ in reducing inflammatory response, oxidative stress, and mortality in animal sepsis, and to investigate its possible mechanism of action. Sepsis was induced by the cecal ligation and puncture (CLP) method in Wistar rats. After surgery, the animals were randomly divided into three groups: sham, sepsis, and sepsis + HDZ (1 mg/kg, s.c.). All groups were monitored for 48 h to assess survival rate, and clinical, hemodynamic, biochemical, and cellular parameters. After euthanasia, blood, spleen, liver, and kidneys were collected for analysis. Blood serum cytokines, tissue myeloperoxidase (MPO) activity, and oxidative stress parameters were assessed. Involvement of the PI3K/Akt pathway was also investigated. Sepsis was successfully induced by the CLP technique. HDZ treatment increased the survival rate (from 50% to 90%), improved glycemia control, reduced the clinical severity sepsis and mean arterial pressure; and prevented increased MPO activity, TNF-α, IL-1ß, IL-10 levels, and oxidative damage markers. Additionally, HDZ significantly prevented the increase of Akt activation in the liver and kidney. HDZ largely mitigated the effects of sepsis by suppressing inflammatory and antioxidant responses via the PI3K/Akt pathway. These findings provide evidence that HDZ can be a new therapeutic alternative for treating sepsis.

Pool Boiling of Nanofluids on Biphilic Surfaces: An Experimental and Numerical Study.

This study addresses the combination of customized surface modification with the use of nanofluids, to infer on its potential to enhance pool-boiling heat transfer. Hydrophilic surfaces patterned with superhydrophobic regions were developed and used as surface interfaces with different nanofluids (water with gold, silver, aluminum and alumina nanoparticles), in order to evaluate the effect of the nature and concentration of the nanoparticles in bubble dynamics and consequently in heat transfer processes. The main qualitative and quantitative analysis was based on extensive post-processing of synchronized high-speed and thermographic images. To study the nucleation of a single bubble in pool boiling condition, a numerical model was also implemented. The results show an evident benefit of using biphilic patterns with well-established distances between the superhydrophobic regions. This can be observed in the resulting plot of the dissipated heat flux for a biphilic pattern with seven superhydrophobic spots, δ = 1/d and an imposed heat flux of 2132 w/m2. In this case, the dissipated heat flux is almost constant (except in the instant t* ≈ 0.9 when it reaches a peak of 2400 W/m2), whilst when using only a single superhydrophobic spot, where the heat flux dissipation reaches the maximum shortly after the detachment of the bubble, dropping continuously until a new necking phase starts. The biphilic patterns also allow a controlled bubble coalescence, which promotes fluid convection at the hydrophilic spacing between the superhydrophobic regions, which clearly contributes to cool down the surface. This effect is noticeable in the case of employing the Ag 1 wt% nanofluid, with an imposed heat flux of 2132 W/m2, where the coalescence of the drops promotes a surface cooling, identified by a temperature drop of 0.7 °C in the hydrophilic areas. Those areas have an average temperature of 101.8 °C, whilst the average temperature of the superhydrophobic spots at coalescence time is of 102.9 °C. For low concentrations as the ones used in this work, the effect of the nanofluids was observed to play a minor role. This can be observed on the slight discrepancy of the heat dissipation decay that occurred in the necking stage of the bubbles for nanofluids with the same kind of nanoparticles and different concentration. For the Au 0.1 wt% nanofluid, a heat dissipation decay of 350 W/m2 was reported, whilst for the Au 0.5 wt% nanofluid, the same decay was only of 280 W/m2. The results of the numerical model concerning velocity fields indicated a sudden acceleration at the bubble detachment, as can be qualitatively analyzed in the thermographic images obtained in this work. Additionally, the temperature fields of the analyzed region present the same tendency as the experimental results.

Torsion of Granulosa Cell Tumor of the Ovary in a Preschool Patient: A Rare Cause of Acute Abdomen.

BACKGROUND Granulosa cell tumor of the ovary is very rare in childhood; its most common clinical manifestation is isosexual precocious puberty. Clinical presentation as acute abdomen due to pain and ovarian torsion is rare, but a granulosa cell tumor must be suspected in a patient with this acute presentation and signs of early puberty. Adult-type granulosa cell tumor is an even rarer occurrence in children. CASE REPORT We report a case of torsion of adult-type granulosa cell tumor of the ovary in a 5-year-old patient with acute abdominal pain and ovarian torsion and highlight the importance of histological diagnosis of this tumor for the therapeutic plan and progression of these patients. CONCLUSIONS Precocious puberty, pain, abdominal distension, and an ultrasonography with suspicion of ovarian torsion are warning signs that may indicate the presence of a gonadal stromal tumor in pediatric patients seen at an emergency unit. These patients require long-term follow-up by a pediatrician and gynecologist because of the potential for late recurrence.

Disparities in Access and Mortality of Patients With ST-Segment-Elevation Myocardial Infarction Using the Brazilian Public Healthcare System: VICTIM Register.

Background There is a scarcity of knowledge as to whether rates of myocardial reperfusion use and 30-day mortality for patients with ST-segment-elevation myocardial infarction are similar among patients using the Brazilian Public Health System (SUS) and those using the private healthcare system. Methods and Results A total of 707 patients were analyzed using the VICTIM (Via Crucis for the Treatment of Myocardial Infarction) register database; 589 patients from the SUS and 118 from the private network with ST-segment-elevation myocardial infarction, who attended hospitals with the capacity to perform primary percutaneous coronary intervention (PCI) were investigated. The timeline, rates of use of PCI, and the 30-day probability of death were investigated, comparing the SUS patients to those in the private system. The mean time between symptom onset and arrival at the PCI hospital was higher for SUS patients compared with users of the private system (25.4±36.5 versus 9.0±21 hours; P<0.001, respectively). Rates of primary PCI were low in both groups, but significantly lower for the SUS patients (45% versus 78%; P<0.001). The 30-day mortality rate of SUS patients was 11.9% and of private patients was 5.9% (P=0.04). In the fully adjusted model, the odds ratio for 30-day mortality for the SUS patients was higher (odds ratio, 2.96; 95% CI, 1.15-7.61; P=0.02). Conclusions The delay in reaching a PCI hospital was almost 3 times higher for the SUS patients. Primary PCI was underused in both groups, especially in the SUS patients. The SUS patients were more likely to die during the 30-day follow-up.

Quality of Intra-Hospital Nutritional Counseling in Patients with STEMI in the Public and Private Health Networks of Sergipe: The VICTIM Register / Qualidade da Orientação Nutricional Intra-hospitalar em Pacientes com IAMcSST das Redes Pública e Privada de Saúde em Sergipe: Registro (VICTIM)

Abstract Background: Having appropriate dietary habits is part of the recommendations after ST-Elevation Myocardial Infarction (STEMI), however, the quality of intra-hospital nutritional counselling in the different health services has been minimally explored. Objective: To evaluate the quality of intra-hospital nutritional counselling among patients with STEMI in the public and private health systems in Sergipe. Methods: A cross-sectional, with data from the Via Crucis for the Treatment of Myocardial Infarction (VICTIM) Register, conducted from April to November of 2017, with individuals aged ≥ 18 years diagnosed with STEMI, in one public health service hospital and three private hospitals. The occurrence and quality of nutritional counselling were analyzed based on current guidelines and the administration of questionnaires. A significance level of 0.05 was adopted. Results: A total of 188 patients were analyzed; 80.3% were from the public health service facility. Among the interviewees, 57.6% of the public health service, and 70.3% of the private hospital patients received intra-hospital nutritional counselling (p = 0.191). The documentation of this practice, in medical records, was lower in the public service (2.6% vs. 37.8%, p < 0.001). A predominance of restrictive orientations was found in the public and private sectors, mainly regarding salt and fat, 52.3% and 70.3% respectively (p = 0.064). Patients from the private service were more counselling to introduce of cardioprotective foods, mainly fruit, vegetable/legume consumption (48.6% vs. 13.2%, p < 0.001). Among those who received counselling, nutritional knowledge was higher in the private sector (68.2% vs. 26.3%, p < 0.001). Conclusion: The intra-hospital nutritional counselling provided to patients with STEMI, in Sergipe, still presents poor quality in both services, especially in the public health system.

Resumo Fundamento: A adequação dos hábitos alimentares faz parte das recomendações pós-infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMcSST); contudo, tem sido pouco explorada a qualidade da orientação nutricional intra-hospitalar nos diferentes serviços de saúde. Objetivo: Avaliar a qualidade da orientação nutricional intra-hospitalar entre pacientes com IAMcSST nas redes de saúde pública e privada em Sergipe. Métodos: Estudo transversal, com dados do Registro Via Crucis para o Tratamento do Infarto do Miocárdio (VICTIM), realizado de abril a novembro de 2017 com indivíduos com idade ≥ 18 anos, diagnosticados com IAMcSST em um hospital público e três privados. Analisaram-se a ocorrência de orientação nutricional e a sua qualidade com base nas diretrizes atuais e por meio de aplicação de questionários, sendo adotado nível de significância de 0,05. Resultados: Foram avaliados 188 voluntários, sendo 80,3% do serviço público. Dentre os entrevistados, 57,6% da rede pública e 70,3% da privada receberam orientação nutricional intra-hospitalar (p = 0,191). O registro dessa prática em prontuário foi menor no serviço público (2,6% versus 37,8%; p < 0,001). Verificou-se o predomínio das orientações restritivas, sobretudo de sal e gorduras, 52,3% e 70,3% no público e no privado, respectivamente (p = 0,064). Quanto à inserção de alimentos cardioprotetores, pacientes da rede privada foram mais beneficiados, principalmente quanto ao consumo de frutas e verduras/legumes (48,6% versus 13,2%, p < 0,001). Entre aqueles que receberam orientação, o conhecimento nutricional foi maior no sistema privado (68,2% versus 26,3%, p < 0,001). Conclusão: A orientação nutricional intra-hospitalar para o IAMcSST em Sergipe apresenta baixa qualidade em ambos os serviços de saúde, sobretudo no público.

Quality of Intra-Hospital Nutritional Counseling in Patients with STEMI in the Public and Private Health Networks of Sergipe: The VICTIM Register.

BACKGROUND: Having appropriate dietary habits is part of the recommendations after ST-Elevation Myocardial Infarction (STEMI), however, the quality of intra-hospital nutritional counselling in the different health services has been minimally explored. OBJECTIVE: To evaluate the quality of intra-hospital nutritional counselling among patients with STEMI in the public and private health systems in Sergipe. METHODS: A cross-sectional, with data from the Via Crucis for the Treatment of Myocardial Infarction (VICTIM) Register, conducted from April to November of 2017, with individuals aged ≥ 18 years diagnosed with STEMI, in one public health service hospital and three private hospitals. The occurrence and quality of nutritional counselling were analyzed based on current guidelines and the administration of questionnaires. A significance level of 0.05 was adopted. RESULTS: A total of 188 patients were analyzed; 80.3% were from the public health service facility. Among the interviewees, 57.6% of the public health service, and 70.3% of the private hospital patients received intra-hospital nutritional counselling (p = 0.191). The documentation of this practice, in medical records, was lower in the public service (2.6% vs. 37.8%, p < 0.001). A predominance of restrictive orientations was found in the public and private sectors, mainly regarding salt and fat, 52.3% and 70.3% respectively (p = 0.064). Patients from the private service were more counselling to introduce of cardioprotective foods, mainly fruit, vegetable/legume consumption (48.6% vs. 13.2%, p < 0.001). Among those who received counselling, nutritional knowledge was higher in the private sector (68.2% vs. 26.3%, p < 0.001). CONCLUSION: The intra-hospital nutritional counselling provided to patients with STEMI, in Sergipe, still presents poor quality in both services, especially in the public health system.

Disparities In The Use Of Drug-eluting Stents For Diabetic Patients With ST-elevation Acute Myocardial Infarction Assisted In the Public versus Private Network - VICTIM Register / Disparidades no Uso de Stents Farmacológicos para Pacientes Diabéticos com Infarto Agudo do Miocárdio com Supradesnivelamento do Segmento ST Assistidos na Rede Pública versus Privada - Registro VICTIM

Abstract Background: Primary angioplasty (PA) with placement of either bare metal or drug-eluting stents (DES) represents the main strategy in the treatment of ST-elevation myocardial infarction (STEMI). Diabetic patients, however, represent a special population in STEMI, with high rates of restenosis and unfavorable clinical outcomes, and with the use of DES, level of evidence A and indication class II, being indicated to reduce these damages. Objectives: To evaluate the DES rate of use in patients with STEMI and in the subgroup of diabetics assisted in the public versus private health network in Sergipe. Methods: This is a population-based, cross-sectional study with a quantitative approach using the data from the VICTIM Register. These were collected in the only four hospitals with capacity to perform PA in Sergipe, from December 2014 to March 2017. Results: A total of 707 patients diagnosed with STEMI were evaluated, of which 589 were attended at SUS and 118 at the private network. The use of DES in PA was lower in SUS compared to the private network in both the total sample (10.5% vs 82.4%, p<0.001) and in subgroup diabetic patients (8.7% vs 90.6%, p < 0.001), respectively. In all hypotheses tested, the level of significance was 5% (p < 0.05). Conclusions: The study reveals a disparity in the use of DES during the performance of PA between the public and private network, both in the total sample and the subgroup for diabetics, with lower rates for SUS users, demonstrating the challenges that need to be overcome in order to achieve quality improvements of the services provided.

Resumo Fundamento: A angioplastia primária (AP) com colocação de stent, seja ele convencional ou farmacológico, representa a principal estratégia no tratamento do infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST). Os pacientes diabéticos, entretanto, representam população especial no IAMCSST, com altas taxas de reestenose e desfechos clínicos desfavoráveis, devendo-se indicar o uso de stents farmacológicos (SF), nível de evidência A e classe de indicação II, para redução destes danos. Objetivo: Avaliar a taxa de uso de SF em pacientes com IAMCSST e no subgrupo dos diabéticos assistidos na rede pública versus privada de saúde em Sergipe. Métodos: Trata-se de um estudo populacional, transversal, com abordagem quantitativa, que utilizou os dados do Registro VICTIM. Estes foram coletados nos quatro únicos hospitais com capacidade para realizar AP em Sergipe, no período de dezembro de 2014 a março de 2017. Em todas as hipóteses testadas, o nível de significância adotado foi de 5% (p < 0,05). Resultados: Foram avaliados 707 pacientes diagnosticados com IAMCSST, dos quais 589 foram atendidos pelo SUS e 118 pela rede privada. O uso de SF na AP foi menor no SUS em comparação com a rede privada, tanto no total da amostra (10,5% vs 82,4%; p < 0,001) quanto no subgrupo dos pacientes diabéticos (8,7% vs 90,6%; p < 0,001), respectivamente. Conclusões: O estudo revela disparidade no uso de SF durante a realização de AP entre a rede pública e privada, tanto na amostra total quanto no subgrupo dos diabéticos, com menores taxas para usuários do SUS, demonstrando os desafios que necessitam ser vencidos para se atingir melhorias na qualidade dos serviços prestados.

Disparidades no tratamento do infarto agudo do miocárdio entre usuários dos Sistema de Saúde Público e Privado em Sergipe / Disparities in acute myocardial infarction treatment between users of the public and private healthcare System in Sergipe

Com a criação do SUS, todos teriam acesso universal, integral e equânime à assistência de saúde de qualidade. Entretanto, existe grande lacuna de estudos escrutinizando o SUS no tocante à qualidade assistencial praticada. Esse fato é especialmente crítico para vítimas de infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST), sendo a responsividade do sistema e o uso da reperfusão em tempo hábil fatores cardinais para obtenção de melhores resultados. Descrever a metodologia empregada no Registro VICTIM que tem como objetivo caracterizar e comparar o acesso e o uso de terapias efetivas e desfechos entre os pacientes com IAMCSST usuários do SUS e do sistema privado atendidos nos hospitais com capacidade de realizar angioplastia em Sergipe, tentanto identificar e mensurar eventuais disparidades na qualidade da assistência.O Registro VICTIM é um estudo observacional, iniciado em dezembro de 2014, e ainda em fase de coleta, com a intenção de investigar a epidemiologia do IAMCSST em Sergipe, os cursos temporal e geográfico dos pacientes até sua admissão em uma instituição com capacidade de realizar angioplastia, uso de terapias de reperfusão, qualidade assistencial recebida durante a linha de cuidado, bem como a mortalidade de 30 dias, comparando-se os resultados obtidos pela população usuária do SUS e do sistema privado.O registro VICTIM é um esforço interinstitucional para identificar oportunidades de melhoria na linha de cuidado para IAMCSST de usuários do SUS e do sistema privado. Com isso, espera-se municiar os gestores públicos de informações técnicas que embasem novas políticas de saúde mais eficientes e equânimes

The Brazilian Unified Health System (SUS) was created to ensure universal, integral and equitable access to quality healthcare to Brazilians. However, studies scrutinizing the quality of the healthcare provided by the SUS are scarce. This is especially critical for patients with ST-elevation myocardial infarction (STEMI), who depend on healthcare system responsiveness and timely reperfusion to achieve better outcomes. To describe the methodology of the VICTIM Registry aimed at characterizing and comparing the access to effective therapies and the outcomes of patients with STEMI, who use the SUS and the private healthcare system at hospitals capable of performing angioplasty in Sergipe. In addition, that registry aimed at identifying and measuring possible disparities in the quality of the care provided. The VICTIM Registry is an observational study, launched in December 2014, being still in the data collection phase, to investigate: the epidemiology of STEMI in Sergipe, the temporal and geographic courses of the patients up to their admission to one of the hospitals capable of performing angioplasty, the reperfusion therapy rates, the quality of the healthcare provided during the event, and the 30-day mortality. It compares the results obtained in the SUS with those of the private healthcare system. The VICTIM Registry is an interinstitutional effort to identify opportunities for healthcare improvement for SUS and private healthcare system patients with STEMI. It is expected to provide healthcare managers with information to support new, more efficient and equitable healthcare policies

Exfoliative erythroderma and palmoplantar hyperkeratosis associated with Majocchi's granuloma by Trichophyton tonsurans in a patient with AIDS / Eritrodermia exfoliativa e hiperqueratosis palmoplantar asociada con granuloma de Majocchi por Trichophyton tonsurans en un paciente con sida

Background. Dermatophytoses are skin superficial mycoses in which clinical manifestations are directly related to the virulence of the infecting microorganism or the host immunity. Case report. We describe a severe case of dermatophytosis associated with exfoliative erythroderma, substantial palmoplantar keratoderma, onychodystrophy affecting all nails, diffuse non-scarring alopecia and tissue fungal invasion by Trichophyton tonsurans, which led us to the diagnosis of AIDS. Direct examination and culture for fungi from skin scraping from two different sites were performed. Biopsy and histopathological exam were also performed on three different sites. Direct examination of the lesions’ scraping revealed septate hyaline hyphae and arthroconidia, identified as Trichophyton tonsurans by culture in glucose Sabouraud agar and Mycosel agar. A scalp biopsy revealed follicular fungal invasion and Majocchi's granuloma. Due to the severity of the presentation we requested an anti-HIV serology, which was positive. The patient was treated with itraconazole, 200mg/day, for 120 days, which promoted a complete regression of the lesions. Conclusions. Severe and atypical forms of dermatophytosis could lead to a diagnosis of AIDS (AU)

Antecedentes. Las dermatofitosis son micosis cutáneas superficiales cuyas manifestaciones clínicas están relacionadas directamente con la virulencia del microorganismo involucrado y la inmunidad del huésped. Caso clínico. Se describe un caso grave de dermatofitosis asociado con eritrodermia exfoliativa, con apreciable queratodermia palmoplantar, onicodistrofia de las 20uñas, alopecia no cicatricial difusa e invasión fúngica del tejido por Trichophyton tonsurans, lo cual permitió establecer el diagnóstico de sida. Se llevó a cabo exploración directa y cultivo de hongos de dos muestras tomadas por raspado en dos localizaciones distintas. También se llevaron a cabo una biopsia de piel y un estudio histopatológico de tres localizaciones. En la exploración directa del raspado de las lesiones se observaron hifas tabicadas hialinas y artroconidios; en el cultivo en agar Sabouraud con glucosa y agar Mycosel se aisló Trichophyton tonsurans. La biopsia de cuero cabelludo mostró una invasión fúngica folicular y la existencia de un granuloma de Majocchi. La gravedad del cuadro motivó la solicitud de la serología para el VIH, que fue positiva. Se trató al paciente con 200mg/día de itraconazol durante 120días, lo que llevó a la remisión completa de las lesiones. Conclusiones. Una dermatofitosis grave o atípica podría considerarse enfermedad reveladora de sida (AU)
