RESUMO
Introducción: El cateterismo urinario es un procedimiento frecuente y en ocasiones es utilizado por fuera de las indicaciones aceptadas para el mismo. Esto aumenta el riesgo de complicaciones vinculadas a su uso, por lo que pueden ser prevenibles. El objetivo del estudio es conocer las características del uso de cateterismo urinario en pacientes ingresados en salas de cuidados moderados de un hospital universitario del tercer nivel de atención, determinar la frecuencia, duración e indicaciones más frecuentes, así como evaluar la presencia de complicaciones asociadas al mismo Metodología: Estudio de corte transversal, realizado en salas de cuidados moderados de un hospital terciario y universitario de Montevideo, Uruguay, el 21 de diciembre de 2022. Se incluyeron pacientes hospitalizados que presentaban o presentaron catéter vesical en la presente internación y se completó la recolección de variables mediante la revisión de la historia clínica. Resultados: De 155 pacientes ingresados en salas de cuidados moderados, a 26 (16,7%) les fue colocado un catéter urinario. La mediana de edad fue 61 años, 80% eran de sexo masculino. La mediana de internación fue de 22 días. En todos los pacientes se utilizó sonda vesical y el 54% fue colocado en el Departamento de Emergencia. En el 46% de los pacientes no se encontró indicación escrita de colocación en la historia clínica. En 50% de los casos no está especificado el motivo de indicación de sonda vesical, mientras que las indicaciones identificadas más frecuentes fueron el control de diuresis (27%) y la desobstrucción de vía urinaria baja (23%). La duración de cateterismo fue de una mediana de 13,5 días, mientras que el 27% de los pacientes la usaron más de 30 días. 35% de los pacientes presentaron complicaciones vinculadas a la sonda vesical, en su mayoría no infecciosas (27%) y 15% presentaron infección urinaria. Estos pacientes tuvieron una duración de cateterismo mayor a los que no presentaron complicaciones (23 vs 10 días, p=0,411). Conclusiones: El catéter vesical fue utilizado en un porcentaje no despreciable de pacientes ingresados en salas de cuidados moderados, de forma prolongada y frecuentemente sin indicación precisa, lo cual expone a un riesgo aumentado de complicaciones vinculadas.
Introduction: Urinary catheterization is a frequent procedure and is sometimes used outside of its accepted indications. This increases the risk of complications related to its use, so they may be preventable. The objective of this study is to know the characteristics of the use of urinary catheterization in patients admitted to moderate care wards of a tertiary care university hospital, to determine the frequency, duration and most frequent indications, as well as to evaluate the presence of associated complications. Methodology: Cross-sectional study, carried out in moderate care wards of a tertiary care and university hospital in Montevideo, Uruguay, on December 21, 2022. Hospitalized patients who present or presented a bladder catheter during the present hospitalization were included, and the collection of variables was completed by reviewing the medical history. Results: Of 155 patients admitted to moderate care wards, 26 (16.7%) had a urinary catheter placed. The median age was 61 years, 80% were male. The median hospitalization was 22 days. In all patients a bladder catheter was used and 54% were placed in the Emergency Department. In 46% of the patients, no written indication for placement was found in the clinical history. In 50% of cases, the reason for indicating the bladder catheter is not specified, while the most frequent indications identified were diuresis control (27%) and lower urinary tract obstruction (23%). The duration of catheterization was a median of 13.5 days, while 27% of the patients used it for more than 30 days. 35% of the patients presented complications related to the bladder catheter, mostly non-infectious (27%) and 15% presented urinary tract infection. These patients had a longer duration of catheterization than those without complications (23 vs 10 days, p=0,411). Conclusions: The bladder catheter was used in a non-negligible percentage of patients admitted to moderate care wards, for a long time and often without a precise indication, which exposes them to an increased risk of related complications.
Introdução: O cateterismo urinário é um procedimento frequente e às vezes é usado fora de suas indicações aceitas. Isso aumenta o risco de complicações relacionadas ao seu uso, portanto, podem ser evitáveis. O objetivo deste estudo é conhecer as características do uso do cateterismo urinário em pacientes internados em enfermarias de cuidados moderados de um hospital universitário terciário, determinar a frequência, duração e indicações mais frequentes, bem como avaliar a presença de complicações associadas ao mesmo. Metodologia: Estudo transversal, realizado em quartos de cuidados moderados de um hospital terciário e universitário em Montevidéu, Uruguai, em 21 de dezembro de 2022. Foram incluídos pacientes que apresentaram ou apresentaram sonda vesical durante a internação atual e a coleta de variáveis ââfoi concluída .revisando o histórico médico. Resultados: Dos 155 pacientes admitidos em enfermarias de cuidados moderados, 26 (16,7%) tiveram um cateter urinário colocado. A idade média foi de 61 anos, 80% eram do sexo masculino. A mediana de internação foi de 22 dias. Em todos os doentes foi utilizada sonda vesical e 54% foram internados no Serviço de Urgência. Em 46% dos pacientes, nenhuma indicação escrita para colocação foi encontrada na história clínica. Em 50% dos casos não é especificado o motivo da indicação da sonda vesical, enquanto as indicações mais frequentes identificadas foram controle da diurese (27%) e desobstrução do trato urinário inferior (23%). A duração do cateterismo foi em média de 13,5 dias, enquanto 27% dos pacientes o utilizaram por mais de 30 dias. 35% dos pacientes apresentaram complicações relacionadas ao cateter vesical, em sua maioria não infecciosas (27%) e 15% apresentaram infecção urinária. Esses pacientes tiveram uma duração mais longa de cateterismo do que aqueles sem complicações (23 vs 10 dias, p=0,411). Conclusões: A sonda vesical foi utilizada em percentual não desprezível de pacientes internados em quartos de cuidados moderados, por tempo prolongado e muitas vezes sem indicação precisa, o que os expõe a um risco aumentado de complicações associadas.
RESUMO
Enteroparasitosis are diseases caused by parasitic agents present in the environment and in the gastrointestinal tract of living beings. In addition, they are still considered neglected diseases, but of great importance for public health, especially when they are related to secondary infections and currently their co-infection profile with COVID-19. The interaction of protozoa and/or helminths with the SARS-CoV-2 virus is timely and its signs and symptoms are confused with other pathogen relationships. In this way, this study aims to correlate the incidence of enteroparasitosis and COVID-19, in the pandemic period from 2020 to April 2022. This is a documentary and exploratory study of secondary data from laboratory tests of patients who were treated and diagnosed with COVID-19 and enteroparasitosis at Hospital Doutor Cloves Bezerra Cavalcante, Municipal Hospital of Bananeiras, Paraíba, Brazil. In the analysis of the database, a significant increase of approximately 48.85% in the incidence of COVID-19 cases from 2020 to 2021 stands out, remaining high until 2022. In contrast, cases of enteroparasites peaked at 48.74% in 2021, followed by an average reduction of 23.12%, with a deviation of 1.49%, in relation to the years 2020 and 2022. It was concluded that COVID-19 is predominantly associated with an increase in secondary infections, highlighting the crucial need to promote health education, improve basic sanitation and guarantee access to health services as essential components in combating the increase in parasitic infections, especially those related to viral pathologies.
As enteroparasitoses são enfermidades originadas por agentes parasitários presentes no meio ambiente e no trato gastrointestinal dos seres vivos. Ademais, ainda são consideradas doenças negligenciadas, porém de grande importância para a saúde pública, em especial, quando estão relacionadas com infecções secundárias e atualmente seu perfil de coinfecção com a COVID-19. A interação de protozoários e/ou helmintos com o vírus SARS-CoV-2 é oportuna e seus sinais e sintomas são confundidos com outras relações de patógenos. Desta maneira, este estudo visa correlacionar a incidência de enteroparasitoses e COVID-19, no período pandêmico de 2020 a abril de 2022. Trata--se de uma pesquisa documental e exploratória, de dados secundários dos exames laboratoriais de pacientes que foram atendidos e diagnosticados com COVID-19 e enteroparasitoses no Hospital Doutor Cloves Bezerra Cavalcante, Hospital Municipal de Bananeiras, Paraíba, Brasil. Na análise da base de dados, destaca-se um aumento significativo de aproximadamente 48,85% na incidência de casos de COVID-19 de 2020 a 2021, mantendo-se elevado até 2022. Em contraste, os casos de enteroparasitas atingiram um pico de 48,74% em 2021, seguido por uma redução média de 23,12%, com um desvio de 1,49%, em relação aos anos de 2020 e 2022. Conclui-se que a COVID-19 está predominantemente associada ao aumento de infecções secundárias, destacando a necessidade crucial de promover a educação em saúde, melhorar o saneamento básico e garantir o acesso aos serviços de saúde como componentes essenciais no combate ao aumento de infecções parasitárias, especialmente aquelas relacionadas a patologias virais.

Invasive infections caused by non-albicans Candida are increasing worldwide. However, there is still a lack of information on invasive candidiasis (IC) in the pediatric setting, including susceptibility profiles and clonal studies. We investigated the clinical, epidemiologic, and laboratory characteristics of IC, possible changes in antifungal susceptibility profiles over time, and the occurrence of clonality in our tertiary children's hospital. We analyzed 123 non-duplicate Candida isolates from sterile sites of pediatric patients in a tertiary hospital in southern Brazil, between 2016 and 2021. Data on demographics, comorbidities, and clinical outcomes were collected. Candida species distribution, antifungal susceptibility profiles, biofilm production, and molecular epidemiology of isolates were assessed using reference methods. The range of IC incidence was 0.88-1.55 cases/1000 hospitalized patients/year, and the IC-related mortality rate was 20.3%. Of the total IC cases, 42.3% were in patients aged < 13 months. Mechanical ventilation, parenteral nutrition, and intensive care unit (ICU) admission were common in this group. In addition, ICU admission was identified as a risk factor for IC-related mortality. The main site of Candida spp. isolation was blood, and non-albicans Candida species were predominant (70.8%). No significant clonal spread was observed among isolates of the three most commonly isolated species, and 99.1% of all isolates were biofilm producers. Non-albicans Candida species were predominant in this study. Notably, clonal expansion and emergence of antifungal drug resistance were not observed in our pediatric setting.
The epidemiology of invasive candidiasis has changed over time and there is still a lack of information in the pediatric setting. Non-albicans Candida species predominated in this study, clonal expansion and emergence of antifungal drug resistance were not observed in our pediatric setting.

Abstract Introduction. Abdominal and neural angiostrongyliasis caused by Angiostrongylus costaricensis and A. cantonensis, respectively, are zoonotic diseases involving snails as intermediate hosts. Colombia has already reported human cases, and the increasing distribution of Lissachatina fulica and Cornu aspersum raises public health concerns due to the potential risk of disease transmission in areas where parasites and hosts coexist. Objective. To identify the presence of Angiostrongylus spp. in snail species L. fulica and C. aspersum in Antioquia, Colombia. Materials and methods. This prospective cross-sectional study had a population of 5,855 L. fulica and C. aspersum snails captured in the ten towns of the Valle de Aburrá (Antioquia, Colombia), 169 samples were collected in 28 sampling points. Lung tissues of the collected snails were dissected and analyzed to detect Angiostrongylus spp. through molecular techniques. Results. Angiostrongylus spp. were identified in both L. fulica and C. aspersum. Angiostrongylus costaricensis was detected in 18 pooled prevalence of 30% (95% CI = 19.2-43.3), and Medellín was the municipality with the highest number of positive samples (33.3%). Seventy-two-point-two percent of the positive places reported the presence of rodents. None of the tests were positive for A. cantonensis. Conclusion. Our findings provide important insights into the epidemiology and distribution of Angiostrongylus spp. in Antioquia, Colombia. The identification of these parasitic nematodes in L. fulica and C. aspersum highlights the potential role of these snails as intermediate hosts in the transmission of Angiostrongylus spp. infections in the Valle de Aburrá, with implications for human and veterinary health.
Resumen Introducción. La angiostrongiliasis abdominal y neura -causadas por Angiostrongylus costaricensis y A. cantonensis, respectivamente- son zoonosis que involucran caracoles como huéspedes intermediarios. Colombia ya ha reportado casos en humanos y la ampliación de la distribución de Lissachatina fulica y Cornu aspersum aumenta la preocupación en salud pública debido al riesgo potencial de transmisión en áreas donde los parásitos y sus huéspedes coexisten. Objetivo. Identificar la presencia de Angiostrongylus spp. en caracoles de las especies L. fulica y C. aspersum en Antioquia (Colombia). Materiales y métodos. Se llevó a cabo un estudio transversal prospectivo con una población de 5.855 caracoles de L. fulica o C. aspersum, capturados en diez ciudades del valle de Aburrá; 169 muestras fueron recolectadas en 28 puntos de muestreo. Se disecaron los tejidos pulmonares de los caracoles y se emplearon técnicas moleculares para detectar la presencia de Angiostrongylus spp. Resultados. Angiostrongylus costaricensis fue detectado en 18 muestras agrupadas (30 %; IC95%: 19,2-43,3), tanto en L. fulica como en C. aspersum. Medellín fue el municipio con el mayor número de muestras positivas (33,3 %). El 72,2 % de los lugares positivos reportaron la presencia de roedores. Ninguna de las pruebas fue positiva para A. cantonensis. Conclusión. Estos hallazgos brindan información importante sobre la distribución de Angiostrongylus spp. en Antioquia (Colombia). La identificación de estos nemátodos en L. fulica y C. aspersum resalta el papel potencial de estos caracoles como huéspedes intermediarios en la transmisión de infecciones por Angiostrongylus en el valle de Aburrá, con implicaciones para la salud humana y veterinaria.
RESUMO
Abstract Introduction: Factors associated with mortality among mechanically ventilated COVID-19 patients have been scarcely studied in Latin America. Objective: To identify factors associated with mortality in mechanically ventilated COVID-19 patients. Methods: This prospective study was undertaken in a single center between April and October 2020, recruiting COVID-19 patients managed with mechanical ventilation. We excluded patients who died within the first 24 hours after endotracheal intubation. Clinical characteristics, laboratory results, ventilation interventions, and outcomes were collected and compared between the deceased and surviving groups. The association between these factors and hospital death was examined, and relevant covariates were included in a multivariate logistic regression model. Results: A total of 273 patients were included (72.5% male), the mortality rate was 37% (95% CI 31% - 43%), and the median age was 63 years (IQR 52-72). The most frequent comorbidity was hypertension (45%). Factors associated with mortality were: older age (OR 1.08; 95% CI 1.051.11), male gender (OR 2.79; 95% CI 1.30-6.01), immunosuppression (OR 3.98; 95% CI 1.57-10.06), thrombocytopenia (OR 3.84; CI 95% 1.47-10.01), driving pressure (OR 1.20; 95% CI 1.07-1.34) and the use of dialysis (OR 4.94; 95% CI 2.56-9.51). Chronic hypertension (OR 0.35; 95% CI 0.17-0.71) and fever on admission (OR 0.51; 95% CI 0.27-0.98) were found to have a protective effect. Conclusions: Older age, male sex, immunosuppression, thrombocytopenia, increased driving pressure, use of dialysis, absence of fever, or arterial hypertension were associated with an increased risk of mortality among mechanically ventilated COVID-19 patients.
Resumen Introducción: Es poco lo que se han estudiado en América Latina los factores asociados con mortalidad en pacientes con COVID-19 ventilados mecánicamente. Objetivo: Identificar los factores asociados con mortalidad en pacientes con COVID-19 manejados con ventilación mecánica. Métodos: Este estudio prospectivo se adelantó en un solo centro entre los meses de abril y octubre de 2020 e incluyó pacientes con COVID-19 manejados con ventilación mecánica. Se excluyeron pacientes que fallecieron en las primeras 24 horas después de la intubación orotraqueal. Se recopilaron datos de las características clínicas, resultados de laboratorio, intervenciones ventilatorias y desenlaces, y se hizo una comparación entre el grupo de pacientes fallecidos y el grupo de sobrevivientes. Se examinó la asociación entre estos factores y la muerte intrahospitalaria, y las covariables relevantes se incluyeron en un modelo multivariable de regresión logística. Resultados: Se incluyó un total de 273 pacientes (72.5% hombres), la tasa de mortalidad fue del 37% (IC 95% 31% - 43%), la mediana de edad fue de 36 años (RIC 52-72) y la comorbilidad más frecuente fue la hipertensión (45%). Los factores asociados con mortalidad fueron: edad avanzada (OR 1.08; IC 95% 1.05-1.11), género masculino (OR 2.79; IC 95% 1.30-6.01), inmunosupresión (OR 3.98; IC 95% 1.57-10.06), trombocitopenia (OR 3.84; CI 95% 1.47-10.01), presión de distensión (OR 1.20; IC 95% 1.07-1.34) y el uso de diálisis (OR 4.94; IC 95% 2.56-9.51). La presencia de hipertensión (OR 0.35; IC 95% 0.17-0.71) y de fiebre (OR 0.51; IC 95% 0.27-0.98) al momento de la hospitalización demostraron tener un efecto protector. Conclusiones: Se encontró asociación entre la edad avanzada, el sexo masculino, la inmunosupresión, la trombocitopenia, una presión de distensión elevada, el uso de diálisis, la ausencia de fiebre o de hipertensión y un mayor riesgo de mortalidad en pacientes con COVID-19 ventilados mecánicamente.

Introduction: Sexually transmitted infections (STIs) cause considerable morbidity worldwide and, depending on the specific pathogen, may lead to serious complications in the female reproductive tract. Incarcerated women are particularly vulnerable to health problems with a disproportionate high rate of STIs, including infections with human papillomavirus (HPV). Methods: Here, cervical swab samples collected from 299 women (18 to 64 years) living in one of the women's prisons of São Paulo, Brazil were submitted for liquid-based cytology to determine the prevalence of precancerous lesions. Furthermore, direct detection of 30 genital HPV genotypes (18 high-risk and 12 low-risk types) and 11 additional STIs (Chlamydia trachomatis, Neisseria gonorrhoeae, Herpes simplex virus 1 and 2, Haemophilus ducreyi, Mycoplasma genitalium and hominis, Treponema pallidum, Trichomonas vaginalis, Ureaplasma parvum and urealyticum) were performed by molecular typing using two PCR-based DNA microarray systems, i.e., EUROArray HPV and EUROArray STI (EUROIMMUN), respectively. Results: The overall prevalence of cytological abnormalities was 5.8%, including five women with low-grade and five women with high-grade squamous intraepithelial lesions. The overall prevalence of HPV was 62.2, and 87.1% of the HPV-positive women were infected with oncogenic high-risk (HR) HPV types. HPV types 16 (24.1%), 33 and 52 (both 10.4%) were the most frequently detected. The prevalence of the other STIs was 72.8%. Up to four different pathogens were found in the infected women, the most frequent being Ureaplasma parvum (45.3%), Mycoplasma hominis (36.2%) and Trichomonas vaginalis (24.8%). Conclusion: The high number of HR-HPV infections and other STIs described here highlights the fact that the Brazilian female prison population requires more attention in the country's health policies. The implementation of screening programs and treatment measures might contribute to a decrease in the incidence of STIs and cervical cancer in this vulnerable population. However, for such measures to be effective, further studies are needed to investigate the best practice to get more women to engage in in-prison prevention programs, e.g., through offering further sexual health education and self-sampling.

The complement system, a vital component of innate immunity, consists of various proteins and pathways crucial for the recognition and elimination of pathogens. In addition, it plays a major role in the initiation of adaptive response through the opsonization of antigens, contributing to B-cell activation and memory maintenance. Deficiencies in complement proteins, particularly C3, can lead to severe and recurrent infections as well as immune complex disorders. Here, we present a case report of two siblings with total C3 deficiency resulting from compound heterozygous mutations in C3 (NM_000064.4): c.305dup; [p.Asn103GlnfsTer66] and c.1269 + 5G>T, previously unreported in C3-related diseases. Both, the index case and her sister, presented a history of recurrent infections since early childhood and one of them developed hemolytic uremic syndrome (HUS). Immunological evaluation revealed absent plasma C3 levels, decreased memory B cells, hypogammaglobulinemia, and impaired response to polysaccharide antigens. The siblings showed partial responses to antimicrobial prophylaxis and vaccination, requiring intravenous immunoglobulin replacement therapy, resulting in clinical improvement. Genetic analysis identified additional risk polymorphisms associated with atypical HUS. This case highlights the importance of comprehensive genetic and immunological evaluations in complement deficiencies, along with the potential role of immunoglobulin replacement therapy in managing associated antibody defects.
RESUMO
Background: Cold agglutinin syndrome (CAS) is a hemolytic anemia mediated by antibodies, mainly IgM, whose maximum activity occurs at 4 °C. It happens secondary to infectious, autoimmune or neoplastic diseases, due to the formation of antibodies that cross-react against erythrocyte antigens, particularly of the I system. Here, we describe a case of CAS associated to Epstein-Barr virus (EBV) reactivation in a patient with primary human immunodeficiency virus (HIV) infection. Clinical case: 22-year old man with no medical history, hospitalized due to mononucleosis and anemic syndrome. Hemoglobin of 3.7 g/dL and elevation of lactate dehydrogenase were documented. In the peripheral blood smear it was observed spherocytosis, polychromasia and nucleated erythrocytes. EBV infection was confirmed with serology and viral load, as well as seronegative HIV infection with positive viral load. The C3d monospecific direct antiglobulin test was positive and an irregular antibody screening revealed the presence of an anti-I antibody. The patient received transfusion support and conservative treatment, with remission of the symptoms 2 weeks after admission. Conclusions: Cold agglutinin syndrome is a rare, potentially fatal complication of infectious mononucleosis, which should be considered in the face of findings suggestive of hemolysis in order to initiate support measures in a timely manner.
Introducción: el síndrome por aglutininas frías (SAF) es una anemia hemolítica mediada por anticuerpos principalmente de tipo IgM, cuya máxima actividad se da a 4 °C. Se presenta en el contexto de enfermedades infecciosas, autoinmunes o neoplásicas por la formación de anticuerpos que tienen reacción cruzada contra antígenos eritrocitarios, particularmente del sistema I. En este trabajo presentamos un caso de SAF asociado a reactivación del virus de Epstein-Barr (VEB) en un paciente con primoinfección por el virus de la inmunodeficiencia humana (VIH). Caso clínico: hombre de 22 años, sin antecedentes patológicos, hospitalizado por síndrome mononucleósico y anémico. Presentó hemoglobina de 3.7 g/dL y elevación de lactato deshidrogenasa. En el frotis de sangre periférica se observó esferocitosis, policromasia y eritrocitos nucleados. Se confirmó infección por VEB con serología y carga viral, así como infección por VIH seronegativa, con carga viral positiva. La prueba de antiglobulina directa monoespecífica a C3d fue positiva y el rastreo de anticuerpos irregulares demostró un anticuerpo anti-I. El paciente recibió soporte transfusional y tratamiento conservador, con remisión del cuadro a las 2 semanas de su ingreso. Conclusiones: el SAF es una complicación poco frecuente de la mononucleosis infecciosa, potencialmente mortal, la cual debe ser considerada ante hallazgos sugestivos de hemólisis con la finalidad de iniciar medidas de soporte de forma oportuna.

Introduction: Few studies have evaluated HAIs in an HIV population; however, studies have suggested that patients with HIV are at a higher risk of contracting HAI because they have high rates of hospitalization and longer hospital stays. Objective: To determine mortality due to Infections Associated with Health Care in Patients with HIV in Paraguay from January to December 2018 to 2021. Methodology: This was an observational, descriptive, and cross-sectional study. The study population consisted of people over 18 years of age who died with a diagnosis of HIV infection and IAAS of both sexes during that period. The study variables were demographic, HIV-related, Baseline Viral Load, Stage of HIV infection at the time of diagnosis, Time from HIV diagnosis to death (in months), comorbidities at the time of death, microorganism isolation, presence, and location. of IAAS. Results: 93 patients with IAAS were included in the study, of which 34.4% (32) were between 20 and 29 years of age and 19.3% (18). Regarding the type of population, 79.3% (73) were in the general population, 77.6% (59) were diagnosed with AIDS, and 68.6% (59) had a baseline CD4 count of less than 200 cells/mm3. The mortality rate in 2020 was 6.7%, during 2018 it was 6.5% and in 2021 it and 6.4%. Conclusion: People with HIV, especially those who have been diagnosed in advanced stages of the disease, are more likely to develop HAIs and are related to mortality. This is due to the presence of multiple opportunistic infections and comorbidities that favor a high number of hospitalizations and longer hospital stays.
Introducción: Hay pocos estudios que hayan evaluado IAAS en una población con VIH, sin embargo, los estudios sugirieron que los pacientes con VIH tienen un mayor riesgo de contraer una IAAS porque tienen altas tasas de hospitalización y estancias hospitalarias más largas. Objetivo: determinar la mortalidad por Infecciones Asociadas a la atención en la Salud en Pacientes con VIH en Paraguay durante los meses de enero a diciembre del año 2018 a 2021. Metodología: Estudio observacional, descriptivo de corte transversal. La población de estudio la constituyeron las personas fallecidas con diagnóstico de infección por VIH e IAAS de ambos sexos, mayor de 18 años de edad, durante ese período. Las variables del estudio fueron demográficas, relacionadas al VIH, Carga Viral basal, Estadio de infección por VIH al momento del diagnóstico, Tiempo desde el diagnóstico de VIH hasta el óbito (meses), comorbilidades al momento del óbito, microorganismo aislado, presencia y localización de IAAS. Resultados: Fueron incluidos en el estudio 93 pacientes con IAAS, de los cuales el 34,4% (32) tuvo una edad entre 20 a 29 años, el 19,3% (18). En cuanto al tipo de población el 79.3% (73) fue población general, 77.6% (59) fue diagnosticado como sida, 68.6% (59) tenían un recuento basal de CD4 menor a 200 células/mm3. La tasa de mortalidad durante el 2020 fue 6,7%, durante el 2018 fue 6,5% y durante el 2021 fue de 6,4%. Conclusión: las personas con VIH en especial aquellas que han sido diagnosticadas en estadios avanzados de la enfermedad tienen mayor posibilidad de desarrollar IAAS y estar relacionadas a la mortalidad. Esto se debe a la presencia de múltiples infecciones oportunistas y comorbilidades que favorece el alto número de internaciones y las estancias mas prolongadas.
RESUMO
Introducción. La infección asociada a catéter venoso central (CVC) es la principal complicación que presentan los pacientes en hemodiálisis en los que se usa este tipo de acceso. Objetivo. Estimar la incidencia de bacteriemia asociada a CVC no tunelizado, analizar la frecuencia de agentes causales y explorar factores de riesgo asociados en niños en hemodiálisis. Población y métodos. Estudio retrospectivo realizado en niños en hemodiálisis por CVC no tunelizado entre el 1 junio de 2015 y el 30 de junio de 2019. Para evaluar factores de riesgo predictores de bacteriemia asociada a CVC, se realizó regresión logística. Los factores de riesgo independiente se expresaron con odds ratio con sus respectivos intervalos de confianza del 95 %. Se consideró estadísticamente significativo un valor de p <0,05. Resultados. En este estudio se incluyeron 121 CVC no tunelizados. La incidencia de bacteriemia fue de 3,15 por 1000 días de catéter. El microorganismo aislado con mayor frecuencia fue Staphylococcus epidermidis (16 casos, 51,5 %). La infección previa del catéter fue el único factor de riesgo independiente encontrado para el desarrollo de bacteriemia asociada a CVC no tunelizado (OR: 2,84; IC95%: 1,017,96; p = 0,04). Conclusiones. El uso prolongado de los CVC no tunelizados para hemodiálisis crónica se asoció con una incidencia baja de bacteriemia. Los gérmenes grampositivos predominaron como agentes causales. La presencia de infección previa del CVC aumentó en casi 3 veces el riesgo de bacteriemia asociada a CVC en nuestra población pediátrica en hemodiálisis.
Introduction. Central venous catheter (CVC)-related infection is the main complication observed in patients undergoing hemodialysis with this type of venous access. Objective. To estimate the incidence of non-tunneled CVC-related bacteremia, analyze the frequency ofcausative agents, and explore associated risk factors in children undergoing hemodialysis. Population and methods. Retrospective study in children receiving hemodialysis via a non-tunneled CVC between June 1 st, 2015 and June 30 th, 2019. A logistic regression was carried out to assess risk factors that were predictors of CVC-related bacteremia. Independent risk factors were described as odds ratios with their corresponding 95% confidence interval (CI). A value of p < 0.05 was considered statistically significant. Results. A total of 121 non-tunneled CVCs were included in this study. The incidence of bacteremia was 3.15 per 1000 catheter-days. The most commonly isolated microorganism was Staphylococcus epidermidis(16 cases, 51.5%). Prior catheter infection was the only independent risk factor for the development of bacteremia associated with non-tunneled CVC (OR: 2.84, 95% CI: 1.017.96, p = 0.04). Conclusions. Prolonged use of non-tunneled CVCs for chronic hemodialysis was associated with a low incidence of bacteremia. Gram-positive microorganisms prevailed among causative agents. A prior CVC infection almost trebled the risk for CVC-related bacteremia in our pediatric population receiving hemodialysis.

Introducción. Los datos de frecuencia de los adenovirus entéricos, sapovirus y astrovirus en casos de gastroenteritis aguda esporádica en Argentina son escasos. Métodos. Diseño descriptivo sobre una selección de muestras de heces de menores de 5 años con diarrea remitidas durante el período 2010-2021, con resultado previo negativo para rotavirus y norovirus. Se estudió la presencia de adenovirus entéricos, sapovirus y astrovirus por métodos moleculares, con posterior genotipificación de las muestras positivas. Resultados. De 574 muestras seleccionadas, en 226 (39,4 %) se identificó al menos uno de los virus estudiados. En particular, se detectaron adenovirus, sapovirus y astrovirus en el 30,7 %, el 5,6 % y el 3,1 %, respectivamente. El adenovirus 41, los sapovirus GI.1 y GI.2, y el astrovirus 1 fueron los más frecuentemente detectados. Se identificaron dos muestras con astrovirus no clásicos. Conclusiones. A pesar de ser menos frecuentes, estos enteropatógenos son responsables de un número considerable de episodios de diarrea esporádica. Por lo tanto, su estudio y vigilancia contribuye significativamente a reducir la brecha de casos no diagnosticados.
Introduction. Data on the frequency of enteric adenoviruses, sapoviruses, and astroviruses in cases of sporadic acute gastroenteritis in Argentina are scarce. Methods. Descriptive design of a selection of fecal samples of children with diarrhea younger than 5 years referred between 2010 and 2021, with a previous negative result for rotavirus and norovirus. The presence of enteric adenovirus, sapovirus, and astrovirus was tested by molecular methods, with subsequent genotyping of positive samples. Results. At least 1 of the tested viruses was detected in 226 (39.4%) of the 574 selected samples. Specifically, adenovirus, sapovirus, and astrovirus were detected in 30.7%, 5.6%, and 3.1% of the samples, respectively. The most frequent viruses detected were adenovirus 41, sapoviruses GI.1 and GI.2, and astrovirus 1. Non-classic astroviruses were detected in 2 samples. Conclusions. Despite being less frequent, these enteropathogens are responsible for a large number of sporadic diarrhea events. Therefore, their study and surveillance contribute significantly to reduce the gap of undiagnosed cases.

Aim: Evaluate the anticandidal effect of Croton heliotropiifolius Kunth essential oil and its interaction with azoles and N-acetylcysteine (NAC) against planktonic cells and biofilms.Materials & methods: Broth microdilution and checkerboard methods were used to evaluate the individual and combined activity with fluconazole and itraconazole (ITRA). The antibiofilm effect of the oil was assessed in 96-well plates alone and combined with ITRA and NAC, and cytotoxicity determined by MTT.Results: The oil inhibited all Candida species growth. The activity was enhanced when associated with ITRA and NAC for planktonic cells and biofilms in formation. The effective concentrations were lower than the toxic ones to V79 cells.Conclusion: C. heliotropiifolius Kunth essential oil is an anticandidal alternative, and can be associated with ITRA and NAC.
Candida is a type of fungus that can cause disease in people. In recent years, the number of available drugs to treat this disease have declined. It is important to search for new drugs. Plants are often used to improve health, so we tested the essential oil of a plant called Croton heliotropiifolius to see if it could kill the fungus. We found that the essential oil could kill the fungus, and could be used with other drugs to improve their effects.

AIMS: This study aimed to investigate the presence of beta-lactams resistance genes and the clonal relationship of clinical isolates of Enterobacterales obtained from patients with and without COVID-19, in a hospital in northeastern Brazil. METHODS AND RESULTS: The study analyzed 45 carbapenem-resistant clinical isolates using enterobacterial repetitive intergenic consensus (ERIC-PCR), PCR, and amplicon sequencing to detect resistance genes (blaKPC, blaGES, blaNDM, blaVIM, and blaIMP). The main species were Klebsiella pneumoniae, Serratia marcescens, and Proteus mirabilis. Detected genes included blaNDM (46.66%), blaKPC (35.55%), and both (17.79%). ERIC-PCR showed multiclonal dissemination and high genetic variability. The main resistance gene was blaNDM, including blaNDM-5 and blaNDM-7. CONCLUSIONS: The presence of Enterobacterales carrying blaKPC and blaNDM in this study, particularly K. pneumoniae, in infections and colonizations of patients with COVID-19 and non-COVID-19, highlights genetic variability and resistance to carbapenems observed in multiple species of this order.
