Microbiological characteristics of bloodstream infections in a reference hospital in northeastern Brazil / Características microbiológicas de infecções da corrente sanguínea em hospital de referência no nordeste do Brasil

Abstract Routine blood culture is used for the detection of bloodstream infections by aerobic and anaerobic bacteria and by common pathogenic yeasts. A retrospective study was conducted in a public hospital in Maceió-AL, by collecting data of all medical records with positive blood cultures. Out of the 2,107 blood cultures performed, 17% were positive with Staphylococcus coagulase negative (51.14%), followed by Staphylococcus aureus (11.21%) and Klebsiella pneumoniae (6.32%). Gram-positive bacteria predominated among positive blood cultures, highlighting the group of Staphylococcus coagulase-negative. While Gram-negative bacteria had a higher number of species among positive blood cultures.

Mortalidad en adultos con COVID-19: experiencia de la Unidad de Cuidados Intensivos de un Hospital de Tercer Nivel de Paraguay

Introducción: diversos factores pueden influir en la mortalidad de pacientes hospitalizados por COVID-19. Objetivo: determinar la mortalidad y los factores asociados a esta en adultos con COVID-19 hospitalizados en la unidad de cuidados intensivos de un Hospital de Tercer Nivel de Paraguay. Metodología: estudio observacional, descriptivo, de asociación cruzada, de corte transversal y temporalmente retrospectivo. Se incluyó historias clínicas de pacientes adultos, de ambos sexos, que tenían diagnóstico confirmado (por prueba de antígeno y/o PCR) de infección por SARS-CoV-2 y que estaban hospitalizados en la unidad de cuidados intensivos de un Hospital General de Tercer Nivel de Paraguay. Resultados: Se incluyeron 116 pacientes, de los cuales el 54 % correspondió al sexo masculino. La edad media fue de 57±12,9 años. El 51 % tenía hipertensión arterial y el 29 % diabetes mellitus. El requerimiento de ventilación mecánica se dio en un 85% de pacientes. El 75 % de los pacientes ventilados tuvo un desenlace fatal. Se encontró una asociación estadísticamente significativa entre la presencia de infecciones bacterianas y requerimiento de hemodiálisis y el desenlace fatal (p=0,0074 y p=0,00011, respectivamente). La media de las edades de los pacientes fallecidos fue de 59,5 años, mientras que el grupo de pacientes que recibieron el alta desde la unidad de cuidados intensivos arrojó una media de 54,2 años. La diferencia entre estas edades en relación con el óbito fue significativa, con una p<0,05. Discusión: La mortalidad general debido a COVID-19 fue de más de 6 por cada 10 pacientes, siendo más alta en aquellos pacientes con ventilación. Aquellos pacientes que presentaron sobreinfección bacteriana o requirieron de hemodiálisis durante el curso de la hospitalización presentaron un peor desenlace en comparación con los pacientes que no presentaron este tipo de complicaciones.

Introduction: Several factors may influence mortality in patients hospitalized with COVID-19. Objective: This research aimed to determine mortality and associated factors in adults with COVID-19 hospitalized in the intensive care unit of a Third Level Hospital in Paraguay. Methodology: Observational, descriptive of cross-association, cross-sectional, and retrospective study. We included medical records of adult patients, of both sexes, who had a confirmed diagnosis (by antigen and/or PCR test) of SARS-CoV-2 infection and who were hospitalized in the intensive care unit of a Third Level General Hospital in Paraguay. Results: We included 116 patients, 54% of whom were male. The mean age was 57 ± 12.9 years. Of participants, 51% had hypertension and 29% diabetes mellitus. Mechanical ventilation was required in 85% of the patients. Of ventilated patients, 75% had a fatal outcome. A statistically significant association was found between the presence of bacterial infections and hemodialysis requirement and fatal outcome (p=0.0074 and p=0.00011, respectively). The mean age of the deceased patients was 59.5 years, while the group of patients discharged from the intensive care unit had a mean age of 54.2 years. The difference between these ages in relation to death was significant, with a p<0.05. Discussion: Overall mortality due to COVID-19 was more than 6 per 10 patients, being higher in those patients with ventilation. Those patients who presented bacterial superinfection or required hemodialysis during hospitalization had a worse outcome compared to patients who did not present this type of complications.

The impact of bariatric and metabolic surgery on the morbidity and mortality of patients infected during the COVID-19 pandemic: a retrospective cohort study

ABSTRACT BACKGROUND: Since the impact of the coronavirus disease 2019 (COVID-19) pandemic in March 2020, several studies have shown a strong relationship between obesity and severe cases of COVID-19. It is imperative to assess whether bariatric surgery exerts a protective effect in such cases. OBJECTIVE: This study aimed to assess the impact of bariatric surgery on the morbidity and mortality in obese patients during the COVID-19 pandemic. A comprehensive search was performed using the PubMed and Cochrane Library databases. DESIGN AND SETTING: Retrospective cohort studies conducted in the Faculdade de Medicina da Universidade Cidade de São Paulo, São Paulo (SP), Brazil. METHODS: The search comprised the following descriptors: "bariatric, surgery, COVID-19". Current retrospective cohort studies that examined the influence of bariatric surgery on the morbidity and mortality of obese patients during the COVID-19 pandemic were considered eligible. RESULTS: After removing duplicates, 184 studies were obtained from the databases. Of these, 181 were excluded from the analysis as they did not meet the eligibility criteria. Patients undergoing postoperative follow-up of bariatric surgery had a similar probability of SARS-CoV-2 infection compared to the general population, and persistent comorbidities were associated with an increased risk and severity of infection. CONCLUSION: Bariatric surgery has a protective effect against severe COVID-19 in the obese population, bringing the prevalence of severe disease cases to levels equivalent to those of the nonobese general population, with a positive impact on morbidity and mortality.

Expresión de ACE2 en cerebro durante el desarrollo y susceptibilidad de infección cerebral por SARS-COV-2 / ACE2 expression in the brain during development and susceptibility to brain infection by SARS-COV-2

Resumen La pandemia COVID-19 se extendió por todo por a la enorme capacidad del coronavirus SARS-CoV-2 para transmitirse entre humanos. El COVID-19 es una amenaza para la salud pública mundial. La entrada de este virus en las células se ve muy facilitada por la presencia de la enzima convertidora de angiotensina 2 (ACE2) en la membrana celular. Hoy en día no tenemos un conocimiento preciso de cómo se expresa este receptor en el cerebro durante el desarrollo humano y, como consecuencia, no sabemos si las células neurales en desarrollo son susceptibles de ser infectadas a través de la transmisión de madre a feto. Revisamos en este artículo los conocimientos sobre la expresión de ACE2 en el cerebro humano en desarrollo, con especial atención a la etapa fetal. Esta etapa corresponde al periodo de formación de la corteza cerebral. La posibilidad de infección por SARS-CoV-2 durante el periodo fetal puede alterar el desarrollo normal de la corteza cerebral. Así pues, aunque se han publicado pocos casos demostrando la transmisión vertical de la infección por SARS-CoV-2, el gran número de jóvenes infectados puede representar un problema sanitario que necesite seguimiento, por la posibilidad de que se originen alteraciones cognitivas y anomalías en el desarrollo de los circuitos corticales, que pueden representar predisposición a padecer problemas mentales a lo largo de la vida.

Abstract The COVID-19 pandemic spread around the world due to the enormous transmission of the SARS-CoV-2 among humans. COVID-19 represents a threat to global public health. The entry of this virus into cells is greatly facilitated by the presence of angiotensin-converting enzyme 2 (ACE2) in the cell membrane. Today we do not have a precise understanding of how this receptor expresses in the brain during human development and, as a consequence, we do not know whether neural cells in the developing brain are susceptible to infection. We review the knowledge about ACE2 expression in the developing human brain, with special attention to the fetal stage. This stage corresponds to the period of the cerebral cortex formation. Therefore, SARS-CoV-2 infection during the fetal period may alter the normal development of the cerebral cortex. Although few cases have been published demonstrating vertical transmission of SARS-CoV-2 infection, the large number of infected young people may represent a problem which requires health surveillance, due to the possibility of cognitive alterations and abnormalities in the development of cortical circuits that may represent a predisposition to mental problems later in life.

Leptospirosis con enfermedad de Weil que debuta como abdomen agudo. Reporte de caso / Leptospirosis with Weil Syndrome debuting with acute abdomen, Case Report

La leptospirosis es una enfermedad de distribución mundial que se ubica dentro de las zoonosis, siendo un punto de partida importante el ambiente donde se desarrolla el paciente, pasa de ser una infección leve, hasta su presentación más complicada que es el síndrome de Weil (presentación diseminada), que al no detectarse a tiempo se relaciona con altas tasas de mortalidad. Su diagnóstico de probabilidad se establece por medio del criterio clínico (signos y síntomas de sospecha), más el nexo epidemiológico, el cual podrá corroborarse con los resultados de los estudios complementarios (marcadores inmunológicos), siendo indispensable para el tratamiento un soporte oportuno y la selección adecuada del esquema antibiótico. A continuación, se expone un caso de una mujer de 25 años con antecedente personal de infección por SARS-CoV-2 (RT-PCR positivo) cuatro meses antes de su ingreso, que presento leptospirosis que debutó con dolor abdominal simulando un abdomen agudo que motivó realización de laparoscopia exploratoria. La serología para leptospira fue positiva y el paciente recibió tratamiento antibiótico específico con evolución favorable.

Leptospirosis is a disease of worldwide that is considered within zoonoses. It is important to know the environment where the patient performs its activities. The clinical presentation goes from a mild infection to its more complicated presentation, the Weil´s Syndrome (disseminated affectation), which is related to high mortality rates if not detected in time. Its probability diagnosis is established based on clinical criteria (signs and symptoms of suspicion), plus the epidemiological link, which can be corroborated with the results of complementary studies (immunological markers). This is essential for the adequate treatment and selection of the antibiotic scheme. The following is a case of a 25-years-old woman with a personal history of SARS-Co V-2 infection (RT-PCR positive) four months before admission, who presented Leptospirosis that debuted with abdominal pain simulating an acute abdomen that required exploratory laparoscopy. Serology for Leptospira was positive and the patient received specific antibiotic treatment with favorable evolution

Usage of Surgical Antibiotic Prophylaxis in Routine Otolaryngologic Surgeries in Turkey

Abstract Introduction: Inappropriate antibiotic use in the world leads to an increase in both health care costs and antibiotic resistance. Surgical antibiotic prophylaxis (SAP) is used by most surgeons, especially in the postoperative period. Objective The aim of the study is to determine the approach of ear, nose, and throat (ENT) specialists to surgical antibiotic prophylaxis in routine surgeries, and to raise awareness regarding inappropriate antibiotic use. Methods ENT specialists from all over Turkey participated in the study by filling out a data collecting form. The form consisted of 6 questions and was sent to specialists via email. Routine ENT operations such as adenoidectomy, tonsillectomy, adenotonsillectomy, ventilation tube application, septoplasty, rhinoplasty, septorhinoplasty (non-complicated), tympanoplasty, and simple mastoidectomy were chosen for the study. Data were analyzed statistically. Results The form results of 110 ENT specialists were evaluated. The rate of participants who used and did not use SAP was 77.3% and 22.7%, respectively. The SAP usage rates of septoplasty, rhinoplasty, and septorhinoplasty operations were 84.7%, 81.2%, and 75.3%, respectively. For tympanoplasty and ventilation tube application operations, the rates were 82.4% and 24.7%, respectively. Finallly, the SAP usage rates of adenoidectomy, tonsillectomy, and adenotonsillectomy were 57.6%, 75.3%, and 72.9%, respectively. Conclusion Otolaryngological surgeries are often classified as clean or clean-contaminated surgeries. In most studies in the literature, it is reported that SAP use is unnecessary in routine otolaryngological surgery. Providing inservice training, regularly updating the prophylaxis guidelines and sharing these guidelines with surgeons may prevent inappropriate SAP use.

Tomographic, microbiological and histological characterization of secondary apical periodontitis: case series

Abstract This case series included a tomographic, microbiological, and histopathological description of 15 secondary apical periodontitis (SAP) lesions obtained by apical microsurgery performed in 10 patients to better understand the etiology and pathogenesis of SAP. Preoperative tomographic analyses were performed through Cone beam computerized tomography - Periapical index (CBCT-PAI), and apical microsurgeries were then carried out. The removed apices were used for microbial culturing and for molecular identification using PCR for the detection of 5 strict anaerobic bacteria (P. gingivalis, P. intermedia, P. nigrescens, T. forsythia, and T.denticola) and 3 viruses Herpes simplex viruses (HSV), Cytomegalovirus (CMG) and Epstein-Barr Virus (EBV) by nested PCR. The removed apical lesions were histologically described. Univariate statistical analyses were performed by using STATA MP/16 (StataCorp LLC, College Station, TX, United States). CBCT-PAI analyses revealed PAI 4 and PAI 5 score lesions that involved cortical plate destruction. Eight SAPs were positive by culture, while nine SAP lesions were positive by PCR. Fusobacterium species were the most frequently cultured organisms in 7 SAP lesions, followed by D. pneumosintes in 3. In contrast, by single PCR, T. forsythia and P. nigrescens were detected in 5 lesions, T. denticola in 4 lesions, and P. gingivalis in 2 lesions. Twelve periapical lesions were granulomas, and the remaining three SAP lesions were radicular cysts. In conclusion, this case series study revealed that secondary apical lesions presented tomographic involvement of PAI 3 to 5, and that most SAP lesions were apical granulomas containing anaerobic and facultative microorganisms.

Resumo Esta série de casos incluiu uma descrição tomográfica, microbiológica e histopatológica de 15 lesões de periodontite apical secundária (SAP) obtidas por microcirurgia apical realizada em 10 pacientes para melhor compreender a etiologia e patogénese do SAP. As análises tomográficas pré-operatórias foram realizadas através de tomografia computadorizada de feixe cônico - índice Periapical (CBCT-PAI), e as microcirurgias apicais foram então realizadas. Os ápices removidos foram utilizados para a cultura microbiana e também para a identificação molecular por PCR para a detecção de 5 bactérias anaeróbias rigorosas (P. gingivalis, P. intermedia, P. nigrescens, T. forsythia, e T.denticola) e 3 vírus Herpes simplex (HSV), Cytomegalovirus (CMG) e Epstein-Barr Virus (EBV) por PCR aninhada. As lesões apicais removidas foram descritas histologicamente. Foram realizadas análises estatísticas univariadas utilizando STATA MP/16 (StataCorp LLC, College Station, TX, Estados Unidos da América). As análises CBCT-PAI revelaram lesões PAI 4 e PAI 5 que envolveram a destruição da placa cortical. Oito SAPs foram positivos por cultura, enquanto nove lesões de SAP foram positivas por PCR. As espécies de Fusobacterium foram os organismos mais frequentemente cultivados em 7 lesões SAP, seguidas por D. pneumosintes em 3. Em contraste, por PCR simples, T. forsythia e P. nigrescens foram detectados em 5 lesões, T. denticola em 4 lesões, e P. gingivalis em 2 lesões. Doze lesões periapicais foram granulomas, e as restantes três lesões SAP foram cistos. Em conclusão, este estudo de série de casos revelou que as lesões apicais secundárias apresentavam envolvimento tomográfico de PAI 3 a 5, e que a maioria das lesões de SAP eram granulomas apicais contendo microrganismos anaeróbios e facultativos.

Does cryptogenic organizing pneumonia change seasonal?

SUMMARY BACKGROUND AND AIM: Meteorological factors affect the respiratory system, and the most important factor is the change in ambient temperature and humidity. We aimed to investigate the seasonal characteristics of patients diagnosed with cryptogenic organizing pneumonia. METHODS: The study included 84 cryptogenic organizing pneumonia, 55 chronic obstructive pulmonary disease, and 42 asthma patients. To determine the characteristics of the disease according to the seasons, the number of attacks and admissions was grouped according to the seasonal characteristics and analyzed for three groups. RESULTS: Among cryptogenic organizing pneumonia and chronic obstructive pulmonary disease patients, males significantly predominated (p<0.001). The hospitalization rate was highest in chronic obstructive pulmonary disease patients but similar to cryptogenic organizing pneumonia and asthma patients (p<0.001). The highest admission rate in cryptogenic organizing pneumonia patients was observed in spring (39.3% in spring, 26.2% in fall, 22.6% in winter, and 11.9% in summer). In winter, cryptogenic organizing pneumonia patients were admitted less frequently than chronic obstructive pulmonary disease and asthma patients. The neutrophil-to-lymphocyte ratio was higher in cryptogenic organizing pneumonia patients than in asthma patients and similar to chronic obstructive pulmonary disease patients. CONCLUSION: As a result of our study, the high rate of diagnosis and admission in the spring in cryptogenic organizing pneumonia suggested that the effect of allergens on the formation of cryptogenic organizing pneumonia should be investigated. In contrast, it should be kept in mind that cryptogenic organizing pneumonia may develop as a prolonged finding of involvement that may occur in the lung parenchyma due to lung infections and/or cold weather triggering during the winter months. In this regard, further studies can be conducted in which allergens and/or the history of infection in patients and meteorological variables are also evaluated.

The impact of COVID-19 on kidney transplant activities in Brazil: a descriptive study

ABSTRACT BACKGROUND: The coronavirus 19 (COVID-19) pandemic has reached services, systems, and world society. Despite its certified efficiency, the Brazilian National Transplant System is not exempt from the side effects of COVID-19. OBJECTIVE: To compare kidney transplantation activity registered in Brazil between the pandemic (2020) and pre-pandemic (2019) periods. DESIGN AND SETTING: A descriptive study was conducted in March 2021. The annual reports of the Brazilian Transplantation Registry for 2019 and 2020 were included in this study. METHODS: We conducted a descriptive study of kidney transplant activity in Brazil in 2019 and 2020. RESULTS: A 23.9% decrease in kidney transplants per million population was observed during the pandemic period (22.9 in 2020 versus 30.1 in 2019). Kidney transplants with a living donor (-58.8%) and in the North Region (-79.5%) experienced the greatest declines. The pandemic waiting list increased by 6.8%, and deaths during the waiting period increased by 36.8%. The number of patients on the waiting list and transplant teams decreased by 31.3% and 9.5%, respectively. CONCLUSION: The COVID-19 pandemic drastically affected Brazil and had a significant negative impact on KT activities in the country.

Patient-nurse ratio as an index related to healthcare-associated infections: a surveillance study / Proporción paciente-enfermera como índice relacionado con infecciones asociadas a la atención de la salud: un estudio de vigilancia

Abstract Background: Healthcare-associated infections (HCAIs) are a hospital problem with a prevalence of approximately 5% in Mexico. HCAIs have been related to the patient-nurse ratio (PNR). This study aimed to analyze the association between PNR and HCAI in a tertiary-level pediatric hospital. Methods: We conducted a descriptive and prospective study at a tertiary-level pediatric hospital in Mexico. Nursing attendance and HCAIs records were documented from July 2017 to December 2018. PNR was calculated using nurse staffing records and patient census. Results: We obtained 63,114 staff attendance data from five hospital departments for the morning, evening, and night shifts. PNR > 2:1 was associated with a 54% (95% confidence interval (CI) 42-167%; p < 0.001) increased risk (odds ratio (OR)) for HCAIs, adjusted by shift staff, special conditions, and surveillance periods. The HCAIs more associated with PNR were urinary tract infections (OR 1.83; 95%CI 1.34-2.46), procedure-related pneumonia (OR 2.08; 95%CI 1.41-3.07), and varicella (OR 2.33; 95%CI 1.08-5.03). Conclusions: A high number of patients per nurse increased the probability of various types of HCAI. PNR needs to be established the HCAI guidelines and policies, as regulating the number of patients per nurse can prevent HCAIs and their complications.

Resumen Introducción: Las infecciones asociadas a la atención a la salud (IAAS) son un problema para los hospitales; en México se ha reportado una prevalencia de alrededor del 5%. Las IAAS se han relacionado con el índice paciente-enfermera (IPE). El objetivo de este estudio fue analizar la asociación entre el IPE y las IAAS en un hospital pediátrico de tercer nivel. Métodos: Se realizó un estudio descriptivo y prospectivo en un hospital pediátrico de tercer nivel en México. Los registros de asistencia de enfermeras y de IAAS se documentaron desde julio de 2017 hasta diciembre de 2018. El IPE se calculó utilizando los registros de personal de enfermería y el censo de pacientes. Resultados: Se obtuvieron 63,114 datos de asistencia del personal de cinco departamentos del hospital para los turnos de mañana, tarde y noche. El IPE > 2:1 se asoció con un aumento del 54% (IC95% 42–167%; p < 0.001) de riesgo (razón de momios [RM]) para IAAS, ajustado por personal de turno, condiciones especiales y periodos de vigilancia. Las IAAS mayormente asociadas con el IPE fueron infecciones del tracto urinario (RM 1.83; IC 95% 1.34-2.46), neumonía relacionada con procedimientos (RM 2.08; IC95% 1.41-3.07) y varicela (RM 2.33; IC95% 1.08-5.03). Conclusiones: Un alto número de pacientes por enfermera aumenta las probabilidades de varios tipos de IAAS. Es fundamental que el IPE se establezca en las guías y políticas en materia de IAAS, ya que regular el número de pacientes por enfermera puede prevenir las IAAS, así como sus complicaciones.

Regional analgesia and surgical site infections after colorectal surgery: a retrospective cohort analysis

Abstract Background The effect of regional analgesia on perioperative infectious complications remains unknown. We therefore tested the hypothesis that a composite of serious infections after colorectal surgery is less common in patients with regional analgesia than in those given Intravenous Patient-Controlled Analgesia (IV-PCA) with opiates. Methods Patients undergoing elective colorectal surgery lasting one hour or more under general anesthesia at the Cleveland Clinic Main Campus between 2009 and 2015 were included in this retrospective analysis. Exposures were defined as regional postoperative analgesia with epidurals or Transversus Abdominis Plane blocks (TAP); or IV-PCA with opiates only. The outcome was defined as a composite of in-hospital serious infections, including intraabdominal abscess, pelvic abscess, deep or organ-space Surgical Site Infection (SSI), clostridium difficile, pneumonia, or sepsis. Logistic regression model adjusted for the imbalanced potential confounding factors among the subset of matched surgeries was used to report the odds ratios along with 95% confidence limits. The significance criterion was p < 0.05. Results A total of 7811 patients met inclusion and exclusion criteria of which we successfully matched 681 regional anesthesia patients to 2862 IV-PCA only patients based on propensity scores derived from potential confounding factors. There were 82 (12%) in-hospital postoperative serious infections in the regional analgesia group vs. 285 (10%) in IV-PCA patients. Regional analgesia was not significantly associated with serious infection (odds ratio: 1.14; 95% Confidence Interval 0.87‒1.49; p-value = 0.339) after adjusting for surgical duration and volume of intraoperative crystalloids. Conclusion Regional analgesia should not be selected as postoperative analgesic technique to reduce infections.

Pediatric inflammatory multisystemic syndrome in Brazil: sociodemographic characteristics and risk factors to death

Abstract Objective: To determine the incidence of MIS-C in Brazil, describe the clinical and sociodemographic characteristics of the pediatric population affected by MIS-C and compare mortality and lethality outcomes with isolated Covid-19 and MIS-C cases. Methods: Observational and retrospective cohort study of cases of MIS-C associated with Covid-19 in the Brazilian population between 04/01/2020 and 04/17/2021. Data from the Ministry of Health's epidemiological bulletin up to the 15th epidemiological week of 2021, were used. The analyzes were descriptive through absolute and relative frequencies. The significance level is 5% in Stata 16.0 package. Results: Between 04/01/2020 and 04/07/2021, 903 cases of MIS-C associated with Covid-19 were notified in Brazil, of which, the largest part (55.26%) were male, between 0 and 4 years old (45.29%), from the Southeast region (38.76%). The deaths (61; 6.7%) were higher in the female gender, between 0 and 4 years old (47.54%) and in the Southeast region (34.43%). It was identified that the risk of death by MIS-C related to Covid-19 is 5.29 (CI = 2.83; 9.87 and P-value = <0.001) times higher in adolescents from 15-19 years old than in other age groups when compared to 0-4 years old children. Also, the residency in North region was as risk factor to death (RR = 3.72, IC = 1.29; 10.74 e P-value = 0.008). Conclusion: In this study, despite the numbers showing more deaths from zero to 4 years old, the risk for teenagers is notably higher. In addition, Brazil's Northern region is a risk factor that reaffirms social inequality and poor access to health.
