    Get PDF
    Este trabalho teve os seguintes objetivos: propor uma sistemática para o estudo e a interpretação da estabilidade e adaptabilidade fenotípica, por meio do modelo de Tucker3; avaliar o uso do gráfico joint plot; e comparar os resultados obtidos pela metodologia de três entradas com os resultados obtidos pelos modelos AMMI e pela análise biplot. Os dados utilizados são relativos a experimentos com 13 genótipos de feijão conduzidos em nove experimentos. Os resultados indicaram que o gráfico joint plot facilita o entendimento da interação tripla e traz ao pesquisador informações mais reais sobre a interação tripla do que a modelagem AMMI de duas entradas; o genótipo 6 foi o que menos contribuiu para a interação, e os genótipos 12, 9 e 5 foram os que mais contribuiram para a interação.The present research had the following objectives: to propose a systematics for the study and the interpretation of the phenotypic stability and adaptability, through Tucker3 models; assess the use of the joint plot; comparing the results obtained by tucker3 model with the results obtained by biplot analysis and AMMI models. The data used are related to the experiments with 13 genotypes of beans that had been lead in 9 distinct experiments. The results indicated that the joint plot graph facilitates the understanding of triple interaction and bring to the researcher more real information about triple interaction, than AMMI modeling of two entries. The genotype 6 was the one which least contributed for the triple interaction and genotypes 12, 9 and 5 were those e which had contributed more for the interaction

    The objective of the study was to evaluate the access, assistance and satisfaction of people with sickle cell disease in relation to the health care provided by the Unified Health System in the Uberlândia city, Minas Gerais, Brazil. Thirty-four people with sickle cell disease were recruited using the snowball sampling method and submitted to semi-structured interview, with collection of demographic, clinical and relationship data and satisfaction with health care. Forty-four percent were not included in the Primary Health Care network, which did not provide several procedures/actions recommended by the Ministry of Health. Ninety-four percent were unsatisfied/partially satisfied with the emergency care provided in the Integrated Care Units. The main reasons for this unsatisfied were ignorance of sickle cell disease by the health team (87.5%), delay in care (81.3%) and inadequate conduct by the health team (59.5%). In conclusion, the access and quality of care provided to people with sickle cell disease by the Primary Health Care network and the Urgency and Emergency Network need to be improved and this improvement is directly related to the training of health teams

    Introduction: The use of street drugs during pregnancy, due to their deleterious effects on the health of the infant, may have clinical implications for neuropsychomotor development. Objective: The aim of this study was to analyse the characteristics of the neuropsychomotor development of infants born from women who used street drugs during pregnancy. Methods: A cross-sectional retrospective study was carried out. A total of 51 medical records of infants weighing less than 1.500 grams, who were born in the Hospital de Clínicas da Universidade Federal de Uberlândia (HC/UFU), Minas Gerais, Brazil, from January 2014 to December 2015 were analysed. Using the Development Screening test Denver II at 6 or 9 months of corrected age performed the neuropsychomotor development evaluation. Statistical analysis included quantitative variables that were described by means of average, medians and standard deviation. Groups were compared by the t test or Mann-Whitney test. The associations of the qualitative variables were evaluated by means of the likelihood ratio test. Results: Of the 51 records analysed, 39.2% belong to the group of children of mothers who used street drugs and 60.8% belong to the group of children of nonuser mothers. The neuropsychomotor development was predominantly abnormal and with a significant difference in the general performance classification (p<0.001) and, specifically, in the coarse motor area (p = 0.003) in the group of infants born to mothers who used street drugs. Conclusion: Infants of mothers who used street drugs had a greater delay in neuropsychomotor development

    Cryptococcosis, a systemic disease caused by the fungus Cryptococcus neoformans/ Cryptococcus gattii is more severe in immunocompromised individuals. This study aimed to analyze the epidemiology of the disease, the molecular characteristics and the antifungal susceptibility of C. neoformans isolated from patients treated in a Brazilian university hospital. This retrospective study was conducted in the Clinical Hospital, Federal University of Uberlândia, and evaluated cases of cryptococcosis and strains of C. neoformans isolated from 2004 to 2013. We evaluated 41 patients, 85% of whom were diagnosed with AIDS. The fungus was isolated from the cerebrospinal fluid (CSF) of 21 patients (51%); 19.5% had fungemia and in 24% the agent was isolated from the CSF and blood, concurrently. Meningoencephalitis was the most frequent (75%) manifestation of infection. Despite adequate treatment, the mortality of the disease was 58.5%. Most isolates (97.5%) presented the VNI genotype (serotype A, var. grubii) and one isolate was genotyped as C. gattii (VGI); all the isolates were determined as mating type MATa and showed susceptibility to the tested antifungals (fluconazole, voriconazole, amphotericin B and 5-flucytosine). Although AIDS detection rates remain stable, opportunistic infections such as cryptococcosis remain as major causes of morbidity and mortality in these patients

    Background and Objectives: Invasive fungal infections are associated with high morbidity and mortality in patients admitted to hospital, including those receiving appropriate therapy. The aim of this study was to evaluate the use of prophylactic and preemptive antifungal therapy; clinical and epidemiological features; and mortality of patients admitted to an infectious disease ward of a public high complexity hospital in Uberlandia, Minas Gerais, Brazil. Methods: This is a retrospective study carried out in the infectious diseases ward of a public university hospital in Brazil. Data from patients hospitalized in 2019 and 2020 who received azole antifungals (fluconazole, itraconazole, or voriconazole), echinocandin (anidulafungin), and polyene (amphotericin B) were collected from medical records. Results: During the study period, 111 patients received one or more antifungal agent. The length of hospital stays of patients (29.35 days; p=0.0252), mean number of days of antibacterial drug use (23.5 days; p=0.0164), a diagnosis of AIDS (p=0.0397), mechanical ventilation (MV) (p<0.001), and presence of a nasoenteral tube (p<0.01) were variables that were associated with death. Fungal infection was confirmed in 79 (71.2%) patients who used antifungal drugs. The most frequent fungi isolated were Candida spp. (36; 32.4%) and Cryptococcus spp. (22; 19.8%), and there was an association between infection with these fungi and mortality (p<0.05; OR: 7.61 and 5.53, respectively). Regarding antifungal therapy indication, 56 (50.4%) patients received it as empirical therapy, 33 (29.7%) as targeted therapy, and 22 (19.8%) as preemptive therapy. Conclusion: The factors that contributed to mortality of the patients were longer hospital stays, AIDS, antibacterial medication use, mechanical ventilation, and presence of a nasoenteral tube. The type of antifungal therapy used did not influence the mortality in these patients.Justificación y Objetivos: Las infecciones fúngicas invasivas presentan una alta morbilidad y mortalidad en los pacientes hospitalizados, incluidos aquellos que utilizan la terapia adecuada. El objetivo fue evaluar la terapia antimicótica profiláctica y preventiva, las características clínicas, epidemiológicas y la mortalidad de pacientes ingresados ​​en una sala de enfermedades infecciosas de un hospital público de alta complejidad en Uberlândia, Minas Gerais, Brasil. Métodos:Este es un estudio retrospectivo realizado en la sala de enfermedades infecciosas de un hospital universitario público en Brasil. Los datos recogidos de las historias clínicas se referían a pacientes hospitalizados en 2019 y 2020 y que utilizaban antifúngicos azoles (fluconazol, itraconazol o voriconazol), equinocandinas (anidulafungina) y polienos (anfotericina B). Resultados: Durante el período, 111 pacientes usaron uno o más antifúngicos. El tiempo de estancia hospitalaria (29,35 días, p= 0,0252), promedio de días de uso de antibacteriano (23,5 días; p=0,0164), SIDA (p=0,0397), uso de ventilación mecánica (VM; p<0,001) y uso de sonda nasoenteral (p<0,01) fueron variables que se relacionaron con el desenlace de muerte. La infección por hongos se confirmó en cultivo en 79 (71,2%) pacientes que usaban medicamentos antimicóticos. Los agentes fúngicos más frecuentes fueron Candida spp. (36; 32,4%) y Cryptococcus spp. (22; 19,8%), mostrando relación entre la infección por estos hongos y la mortalidad (p<0,05; 7,61 y 5,53, respectivamente). En cuanto a la terapia, 56 (50,4%) pacientes estaban en terapia empírica; 33 (29,7%) la utilizaron como terapia diana; y 22 (19,8%) la utilizaron como terapia preventiva. Conclusión: La mortalidad fue más frecuente entre los pacientes con mayor tiempo de internación, que tenían SIDA y que utilizaron antibióticos, ventilación mecánica y sonda nasoenteral en algún momento de la internación. El tipo de terapia antifúngica no influyó en la mortalidad de estos pacientes.Justificativa e Objetivos: As infecções fúngicas invasivas apresentam alta morbimortalidade para pacientes hospitalizados, inclusive para aqueles em uso de terapia apropriada. O objetivo foi avaliar a terapia antifúngica profilática e preemptiva, as características clínicas e epidemiológicas, e a mortalidade de pacientes internados em uma enfermaria de doenças infecciosas de um hospital público de alta complexidade de Uberlândia, Minas Gerais, Brasil. Métodos: Trata-se de estudo retrospectivo realizado em uma enfermaria de doenças infecciosas. Os dados coletados dos prontuários foram referentes aos pacientes internados nos anos de 2019 e 2020 e que fizeram uso de antifúngicos azólicos (fluconazol, itraconazol ou voriconazol), equinocandinas (anidulafungina) e poliênicos (anfotericina B). Resultados: Durante o período, 111 pacientes usaram um ou mais antifúngicos. O tempo de internação (29,35 dias, p= 0,0252), média de dias de uso de antibacterianos (23,5 dias; p=0,0164), aids (p=0,0397), uso de ventilação mecânica (VM; p <0,001) e uso de sonda nasoenteral (p<0,01) foram variáveis que se relacionaram com desfecho morte. A infecção por fungos foi confirmada em cultura para 79 (71,2%) pacientes em terapia antifúngica. Os fungos mais frequentes foram Candida spp. (36; 32,4%) e Cryptococcus spp. (22; 19,8%), mostrando relação da infecção por esses fungos com a mortalidade (p<0,05; OR: 7,61 e 5,53, respectivamente). Quanto à terapia, 56 (50,4%) pacientes estavam em terapia empírica; 33 (29,7%) usaram como terapia alvo; e 22 (19,8%) usavam como terapia preemptiva. Conclusão: A mortalidade foi mais frequente entre os pacientes com maior tempo de hospitalização, que tinham aids e que fizeram uso de antibióticos, de ventilação mecânica e de sonda nasoenteral em algum momento da internação. O tipo de terapia antifúngica não influenciou a mortalidade desses pacientes
