Nosocomial Bloodstream Infections in Brazilian Pediatric Patients: Microbiology, Epidemiology, and Clinical Features

Background: Nosocomial bloodstream infections (nBSIs) are an important cause of morbidity and mortality and are the most frequent type of nosocomial infection in pediatric patients.Methods: We identified the predominant pathogens and antimicrobial susceptibilities of nosocomial bloodstream isolates in pediatric patients (<= 16 years of age) in the Brazilian Prospective Surveillance for nBSIs at 16 hospitals from 12 June 2007 to 31 March 2010 (Br SCOPE project).Results: in our study a total of 2,563 cases of nBSI were reported by hospitals participating in the Br SCOPE project. Among these, 342 clinically significant episodes of BSI were identified in pediatric patients (<= 16 years of age). Ninety-six percent of BSIs were monomicrobial. Gram-negative organisms caused 49.0% of these BSIs, Gram-positive organisms caused 42.6%, and fungi caused 8.4%. the most common pathogens were Coagulase-negative staphylococci (CoNS) (21.3%), Klebsiella spp. (15.7%), Staphylococcus aureus (10.6%), and Acinetobacter spp. (9.2%). the crude mortality was 21.6% (74 of 342). Forty-five percent of nBSIs occurred in a pediatric or neonatal intensive-care unit (ICU). the most frequent underlying conditions were malignancy, in 95 patients (27.8%). Among the potential factors predisposing patients to BSI, central venous catheters were the most frequent (66.4%). Methicillin resistance was detected in 37 S. aureus isolates (27.1%). of the Klebsiella spp. isolates, 43.2% were resistant to ceftriaxone. of the Acinetobacter spp. and Pseudomonas aeruginosa isolates, 42.9% and 21.4%, respectively, were resistant to imipenem.Conclusions: in our multicenter study, we found a high mortality and a large proportion of gram-negative bacilli with elevated levels of resistance in pediatric patients.Pfizer, Inc.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Inst Oncol Pediat IOP GRAAC, São Paulo, BrazilHosp Israelita Albert Einstein, São Paulo, BrazilUniversidade Federal de São Paulo UNIFESP, São Paulo, BrazilHosp 9 Julho, São Paulo, BrazilSanta Casa Porto Alegre, Porto Alegre, RS, BrazilHosp Conceicao, Porto Alegre, RS, BrazilHosp Base, Brasilia, DF, BrazilHosp Walter Cantidio, Fortaleza, Ceara, BrazilHosp Diadema, São Paulo, BrazilHosp Espanhol, Salvador, BA, BrazilHosp Coracao, Natal, RN, BrazilHosp UNIMED, Natal, RN, BrazilHosp Clin Goiania, Goiania, Go, BrazilHosp Rim & Hipertensao, São Paulo, BrazilUniv Fed Triangulo Mineiro, Uberaba, MG, BrazilVirginia Commonwealth Univ, Richmond, VA USAUniversidade Federal de São Paulo UNIFESP, São Paulo, BrazilFAPESP: 2006/57700-0Web of Scienc

WSES/GAIS/WSIS/SIS-E/AAST global clinical pathways for patients with skin and soft tissue infections

Skin and soft-tissue infections (SSTIs) encompass a variety of pathological conditions that involve the skin and underlying subcutaneous tissue, fascia, or muscle, ranging from simple superficial infections to severe necrotizing infections. Together, the World Society of Emergency Surgery, the Global Alliance for Infections in Surgery, the Surgical Infection Society-Europe, The World Surgical Infection Society, and the American Association for the Surgery of Trauma have jointly completed an international multi-society document to promote global standards of care in SSTIs guiding clinicians by describing reasonable approaches to the management of SSTIs. An extensive non-systematic review was conducted using the PubMed and MEDLINE databases, limited to the English language. The resulting evidence was shared by an international task force with different clinical backgrounds.Peer reviewe

WSES/GAIS/SIS-E/WSIS/AAST global clinical pathways for patients with intra-abdominal infections

Intra-abdominal infections (IAIs) are common surgical emergencies and have been reported as major contributors to non-trauma deaths in hospitals worldwide. The cornerstones of effective treatment of IAIs include early recognition, adequate source control, appropriate antimicrobial therapy, and prompt physiologic stabilization using a critical care environment, combined with an optimal surgical approach. Together, the World Society of Emergency Surgery (WSES), the Global Alliance for Infections in Surgery (GAIS), the Surgical Infection Society-Europe (SIS-E), the World Surgical Infection Society (WSIS), and the American Association for the Surgery of Trauma (AAST) have jointly completed an international multi-society document in order to facilitate clinical management of patients with IAIs worldwide building evidence-based clinical pathways for the most common IAIs. An extensive non-systematic review was conducted using the PubMed and MEDLINE databases, limited to the English language. The resulting information was shared by an international task force from 46 countries with different clinical backgrounds. The aim of the document is to promote global standards of care in IAIs providing guidance to clinicians by describing reasonable approaches to the management of IAIs.Peer reviewe

A pandemic recap : lessons we have learned

On January 2020, the WHO Director General declared that the outbreak constitutes a Public Health Emergency of International Concern. The world has faced a worldwide spread crisis and is still dealing with it. The present paper represents a white paper concerning the tough lessons we have learned from the COVID-19 pandemic. Thus, an international and heterogenous multidisciplinary panel of very differentiated people would like to share global experiences and lessons with all interested and especially those responsible for future healthcare decision making.

Ten golden rules for optimal antibiotic use in hospital settings: the WARNING call to action

Antibiotics are recognized widely for their benefits when used appropriately. However, they are often used inappropriately despite the importance of responsible use within good clinical practice. Effective antibiotic treatment is an essential component of universal healthcare, and it is a global responsibility to ensure appropriate use. Currently, pharmaceutical companies have little incentive to develop new antibiotics due to scientific, regulatory, and financial barriers, further emphasizing the importance of appropriate antibiotic use. To address this issue, the Global Alliance for Infections in Surgery established an international multidisciplinary task force of 295 experts from 115 countries with different backgrounds. The task force developed a position statement called WARNING (Worldwide Antimicrobial Resistance National/International Network Group) aimed at raising awareness of antimicrobial resistance and improving antibiotic prescribing practices worldwide. The statement outlined is 10 axioms, or “golden rules,” for the appropriate use of antibiotics that all healthcare workers should consistently adhere in clinical practice

PRIMEIRO WORKSHOP DE PREVENÇÃO DE IRAS E USO RACIONAL DE ANTIMICROBIANOS PARA PROGRAMAS DE RESIDÊNCIA MÉDICA DE HOSPITAL TERCIÁRIO NO DISTRITO FEDERAL

As infecções relacionadas à assistência em saúde (IRAS) são consideradas hoje, um problema de grande impacto na morbi-mortalidade de pacientes, principalmente em áreas críticas. No entanto, algumas medidas de prevenção quando realizadas em conjunto, são fundamentais para que tais infecções não ocorram. Associado a isto, alta prevalência de germes multidroga resistentes, tendo como seu catalisador o uso irracional de antimicrobianos, também aponta como grande problema de saúde pública em âmbito mundial. Considerando a residência médica como um momento de formação, no qual é imprescindível avaliar o paciente de forma global, independentemente da especialidade a qual se destina, iniciou-se no mês de maio de 2023,promovido pelo Núcleo de controle de Infecção hospitalar (NCIH), o primeiro workshop de prevenção de IRAS e uso racional de antimicrobianos para Programas de Residência Médica do Hospital de Base do Distrito Federal, com duração de seis semanas, o qual tinha como objetivos, orientar o residente a cerca das principais medidas de prevenção das Infecções relacionadas à assistência (IRAS); reconhecimento e diagnóstico das principais IRAS, tratamento empírico adequado com base nos protocolos institucionais, considerando o uso racional de antimicrobianos e perfil de resistência dos microorganismos da instituição, reconhecimento e o uso adequado dos antimicrobianos no contexto da sepse. O curso foi dividido em seis módulos, e cada módulo é composto por treinamentos teóricos, feitos por vídeo aula gravados pela equipe de enfermeiros e médicos do NCIH, com realização de pós teste e também treinamentos práticos em centro de simulação realística disponível na instituição. No treinamento prático, os médicos residentes foram expostos a situações clínicas, as quais eram interligadas com medidas de biosegurança, indicação, inserção e manejo de dispositivos, dentro das condutas seguras preconizadas

Prevalence of methicillin-resistant Staphylococcus aureus (MRSA) among patients visiting the emergency room at a tertiary hospital in Brazil

We surveyed patients seen at the emergency room at a tertiary hospital in Brazil from August to November 1997. All patients' (n = 600) anterior nares were cultured for MRSA; the results were confirmed by oxacillin disk diffusion methods and by detection of the mecA gene with PCR. Bacteria were found in 93.3% (560) of the patients and MRSA in 0.7% (n = 4). One patient had community-acquired MRSA. We concluded that MRSA is uncommon among patients visiting the emergency room. The presence of community-acquired MRSA can lead to serious medical and epidemiological issues, although initial clinical presentation may not differ from that of infections with other staphylococci. The empirical use of vancomycin for suspected community-acquired infections is seldom warranted

Klebsiella pneumoniae with multiple antimicrobial resistance

A Klebsiella pneumoniae strain was isolated from the urine of a patient at one of the centers participating in the 2001 edition of the MYSTIC program in Brazil. The initial phenotypic findings of the isolated K. pneumoniae presented an unusual MIC of 8 mug/mL to meropenem, 2 mug/mL to imipenem, elevated MICs to broad spectrum cephalosporins (ceftazidime/cefotaxime/cefepime MIC > 256 mug/mL), aminoglycosides (gentamycin > 256 mug/mL and tobramycin = 48 mug/mL), piperacillin/tazobactam (MIC > 256 mug/mL) and susceptibility to ciprofloxacin (MIC = 0.25 mug/mL). The strain also tested positive for ESBL production with double-disk and E-test methodologies. More detailed investigation revealed that the strain produced a SHV-4 type enzyme and also lacked a 36 kDa outer membrane porin
