How Mild Is the Mild Long COVID? A Comprehensive Neuropsychological Assessment of Patients with Cognitive Complaints.

The global impact of the Coronavirus Disease (COVID-19) pandemic has extended beyond physical health, leading to widespread mental health issues. Beyond respiratory symptoms, there is a growing concern about long-term cognitive effects, particularly in individuals who experienced mild cases of the infection. We aimed to investigate the neuropsychological aspects of long-term COVID-19 in non-hospitalized adults compared with a control group. This cross-sectional study included 42 participants, 22 individuals with a history of mild COVID, and 20 healthy controls. The participants were recruited from the community and underwent a comprehensive neuropsychological assessment. Participants from the mild COVID group reported cognitive symptoms persisting for an average of 203.86 days and presented a higher frequency of psychological treatment history (81.8%) compared with the control group (25.0%). History of anxiety disorders was more prevalent in the mild COVID group (63.6%) than in the control group (20.0%). Significant reductions in verbal working memory were observed in the mild COVID group. Levels of anxiety were found to have a significant impact on difficulties with visual recognition memory. This study reveals important neuropsychological alterations in individuals following mild COVID-19, emphasizing executive functions deficits. Our findings underscore the persistence of these deficits even in non-hospitalized cases, suggesting potential inflammatory mechanisms in the central nervous system. The study highlights the need for comprehensive assessments and targeted interventions to address the diverse cognitive impacts on individuals recovering from COVID-19.

Extrahepatic cholestasis associated with paracoccidioidomycosis: Challenges in the differential diagnosis of biliopancreatic neoplasia.

BACKGROUND: Paracoccidioidomycosis (PCM) may involve the hepatic pedicle and peripancreatic lymph nodes, cause damage to the bile duct and manifest, exceptionally, in combination with extrahepatic cholestasis (EHC), making investigation and treatment challenging. AIM: To investigate the management of patients with visceral PCM admitted with EHC. METHODS: All patients diagnosed with PCM treated in a public, tertiary teaching hospital between 1982 and 2020 were retrospectively evaluated. Those also identified with EHC were allocated to two groups according to the treatment approach for the purpose of comparing clinical, laboratory, and imaging findings, resources used for etiological diagnosis, treatment results, and prognosis. Statistical analyses were performed using the linear mixed-effects model (random and fixed effects), which was adjusted using the PROC MIXED procedure of the SAS® 9.0 software, and Fisher's exact test. RESULTS: Of 1645 patients diagnosed with PCM, 40 (2.4%) had EHC. Of these, 20 (50.0%) lived in the rural area and 29 (72.5%) were men, with a mean age of 27.1 years (3-65 years). Jaundice as first symptom and weight loss of at least 10 kg were observed in 16 patients (40.0%), and a mass in the head of the pancreas was observed in 8 (20.0%). The etiological diagnosis was made by tissue collection during surgery in 4 cases (10.0%) and by endoscopic methods in 3 cases (7.5%). Twenty-seven patients (67.5%) received drug treatment alone (Group 1), whereas 13 (32.5%) underwent endoscopic and/or surgical procedures in combination with drug treatment (Group 2). EHC was significantly reduced in both groups (40.7% in Group 1, with a mean time of 3 months; and 38.4% in Group 2, with a mean time of 7.5 months), with no statistically significant difference between them. EHC recurrence rates, associated mainly with treatment nonadherence, were similar in both groups: 37% in Group 1 and 15.4% in Group 2. The mortality rate was 18.5% in Group 1 and 23% in Group 2, with survival estimates of 71.3% and 72.5%, respectively, with no statistically significant difference. CONCLUSION: Although PCM-related EHC is rare, it needs to be included in the differential diagnosis of malignancies, as timely treatment can prevent hepatic and extrahepatic sequelae.

Evaluation of the adherence to surgical antibiotic prophylaxis recommendations and associated factors in a University Hospital: A cross-sectional study.

BACKGROUND: Surgical antibiotic prophylaxis (SAP) is an important preventive measure, aiming to minimize surgical site infections. However, despite evidence-based guidelines, adherence to SAP protocols remains suboptimal in clinical practice. The aim of this study was to assess the adequacy of SAP in a high-complexity hospital and investigate associated factors. METHODS: A cross-sectional design was conducted, involving surgeries performed by expert teams in cardiology, urology, neurology, and gastrointestinal. SAP prescriptions were evaluated based on indication, antibiotic choice, dosage, and duration, according to the hospital protocol. Data analysis included descriptive statistics and association tests between protocol adherence and patient demographics, clinical variables, surgical teams, and types of surgeries. RESULTS: Out of 1,864 surgeries, only 20.7% adhered to SAP protocols. Lower adherence rates were observed for antibiotic choice and duration of prophylaxis. Neurological surgeries exhibited significantly lower adherence, particularly concerning antibiotic choice and duration. Factors associated with nonadherence included elevated preoperative blood glucose levels, prolonged hospitalization, and extended surgical duration. Logistic regression analysis identified surgical teams as significant factors influencing protocol adherence. CONCLUSIONS: Despite the relatively high adherence to antibiotic dosage, challenges persist in antibiotic choice and duration adjustment. Poor glycemic control, prolonged surgery, and surgical teams were variables associated with inappropriate practice.

Risk factors and mortality of candidemia in a children's public hospital in Sao Paulo, Brazil.

Candida bloodstream infections in children are of special concern in neonatal and pediatric intensive care and patients with comorbidities. This study aimed to estimate the incidence and risk factors associated with mortality in candidemia cases occurring in a public children's hospital in Ribeirao Preto, Brazil. It is a retrospective transversal study. Every patient under the age of 18 admitted to the study facility from January 1, 2013, to December 31, 2019, was considered potentially eligible to be included if they had candidemia. We collected clinical data from medical records. We included 113 blood cultures yielding positive results for Candida. The incidence rate was 2.12 per 1000 admissions. The most common Candida species was Candida parapsilosis. Septic shock during the candidemia episode was the only clinical outcome associated with a relative risk-adjusted (RRa) of 2.77 with an interval >1 (1.12-6.85). Our findings show that the incidence rate and mortality rates of candidemia are in line with those in other children's services in Brazil. We found a global mortality rate of 28.31% (32/113) from candidemia episodes. We highlight the predominance of non-albicans Candida species including C. parapsilosis. Septic shock was the most important factor showing a significant risk of mortality.

Matrix metalloproteinases are associated with severity of disease among COVID-19 patients: A possible pharmacological target.

COVID-19 is a devastating disease and imbalanced matrix metalloproteinase (MMP) activity may contribute to its pathophysiology. This exploratory study examined whether increased circulating concentrations of MMP-2 and MMP-9, and their endogenous inhibitors, the tissue inhibitors of MMP (TIMP)-1, TIMP-2, TIMP-3 and TIMP-4 are persistently found in patients 2 weeks after their recovery from severe or critical COVID-19 as compared with those in healthy controls. Subjects who had severe (n = 26) or critical (n = 25) PCR-confirmed COVID-19 and healthy controls (n = 21) had blood samples drawn 2 weeks after recovery and serum MMP-2, MMP-9, TIMP-1, TIMP-2, TIMP-3 and TIMP-4 were determined using two Human Luminex® Discovery Assays. Circulating MMP activity was also determined by gel zymography. Patients who had severe or critical COVID-19 had increased circulating MMP-9 and MMP-2 concentrations, with increased MMP-9/TIMP-1 and MMP-2/TIMP-2 ratios indicating increased MMP activity, confirmed by gel zymography (all p < 0.05). Higher circulating MMP-9 (but not MMP-2) concentrations were found in critical versus severe COVID-19 (p < 0.05). We found increased circulating MMP-9 and MMP-2 concentrations and activity many days after recovery from the acute disease, with MMP-9 levels associated with disease severity. These biochemical alterations suggest that MMP-2 and MMP-9 may be important pharmacological targets in COVID-19.

Aetiology and use of antibiotics in pregnancy-related infections: results of the WHO Global Maternal Sepsis Study (GLOSS), 1-week inception cohort.

BACKGROUND: Pregnancy-related infections are important contributors to maternal sepsis and mortality. We aimed to describe clinical, microbiological characteristics and use of antibiotics by source of infection and country income, among hospitalized women with suspected or confirmed pregnancy-related infections. METHODS: We used data from WHO Global Maternal Sepsis Study (GLOSS) on maternal infections in hospitalized women, in 52 low-middle- and high-income countries conducted between November 28th and December 4th, 2017, to describe the frequencies and medians of maternal demographic, obstetric, and clinical characteristics and outcomes, methods of infection diagnosis and causative pathogens, of single source pregnancy-related infection, other than breast, and initial use of therapeutic antibiotics. We included 1456 women. RESULTS: We found infections of the genital (n = 745/1456, 51.2%) and the urinary tracts (UTI) (n = 531/1456, 36.5%) to be the most frequent. UTI (n = 339/531, 63.8%) and post-caesarean skin and soft tissue infections (SSTI) (n = 99/180, 55.0%) were the sources with more culture samples taken and microbiological confirmations. Escherichia coli was the major uropathogen (n = 103/118, 87.3%) and Staphylococcus aureus (n = 21/44, 47.7%) was the commonest pathogen in SSTI. For 13.1% (n = 191) of women, antibiotics were not prescribed on the same day of infection suspicion. Cephalosporins (n = 283/531, 53.3%) were the commonest antibiotic class prescribed for UTI, while metronidazole (n = 303/925, 32.8%) was the most prescribed for all other sources. Ceftriaxone with metronidazole was the commonest combination for the genital tract (n = 98/745, 13.2%) and SSTI (n = 22/180, 12.2%). Metronidazole (n = 137/235, 58.3%) was the most prescribed antibiotic in low-income countries while cephalosporins and co-amoxiclav (n = 129/186, 69.4%) were more commonly prescribed in high-income countries. CONCLUSIONS: Differences in antibiotics used across countries could be due to availability, local guidelines, prescribing culture, cost, and access to microbiology laboratory, despite having found similar sources and pathogens as previous studies. Better dissemination of recommendations in line with antimicrobial stewardship programmes might improve antibiotic prescription.

Updates and future directions regarding hand hygiene in the healthcare setting: insights from the 3rd ICPIC alcohol-based handrub (ABHR) task force.

Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) pose threats to global health. Effective hand hygiene is essential for preventing HAIs and the spread of AMR in healthcare. We aimed to highlight the recent progress and future directions in hand hygiene and alcohol-based handrub (ABHR) use in the healthcare setting. In September 2023, 42 experts in infection prevention and control (IPC) convened at the 3rd International Conference on Prevention and Infection Control (ICPIC) ABHR Taskforce in Geneva, Switzerland. The purpose of this meeting was to provide a synthesis of recent evidence and formulate a research agenda on four critical areas for the implementation of effective hand hygiene practices: (1) ABHR formulations and hand rubbing techniques, (2) low-resource settings and local production of ABHR, (3) hand hygiene monitoring and technological innovations, and (4) hand hygiene standards and guidelines.

Investigating autonomic nervous system dysfunction among patients with post-COVID condition and prolonged cardiovascular symptoms.

Heart Rate Variability (HRV) and arterial pressure (AP) variability and their responses to head-up tilt test (HUTT) were investigated in Post-COVID-19 syndrome (PCS) patients reporting tachycardia and/or postural hypotension. Besides tachycardia, PCS patients also showed attenuation of the following HRV parameters: RMSSD [square root of the mean of the sum of the squares of differences between adjacent normal-to-normal (NN) intervals] from statistical measures; the power of RR (beat-to-beat interval) spectra at HF (high frequency) from the linear method spectral analysis; occurrence of 2UV (two unlike variation) pattern of RR from the nonlinear method symbolic analysis; and the new family of statistics named sample entropy, when compared to control subjects. Basal AP and LF (low frequency) power of systolic AP were similar between PCS patients and control subjects, while 0 V (zero variation) patterns of AP from the nonlinear method symbolic analysis were exacerbated in PCS patients. Despite tachycardia and a decrease in RMSSD, no parameter of HRV changed during HUTT in PCS patients compared to control subjects. PCS patients reassessed after 6 months showed higher HF power of RR spectra and a higher percentage of 2UV pattern of RR. Moreover, the reassessed PCS patients showed a lower occurrence of 0 V patterns of AP, while the HUTT elicited HR (heart rate) and AP responses identical to control subjects. The HRV and AP variability suggest an autonomic dysfunction with sympathetic predominance in PCS patients. In contrast, the lack of responses of HRV and AP variability indices during HUTT indicates a marked impairment of autonomic control. Of note, the reassessment of PCS patients showed that the noxious effect of COVID-19 on autonomic control tended to fade over time.

Genomic epidemiology of SARS-CoV-2 in large university hospital cohort: the UnCoVER-Brazil project.

This work aimed to study the role of different SARS-CoV-2 lineages in the epidemiology of multiple waves of the COVID-19 pandemic in Ribeirão Preto (São Paulo state), with comparison within Brazil and globally. Viral genomic sequencing was combined with clinical and sociodemographic information of 2,379 subjects at a large Brazilian hospital. On the whole 2,395 complete SARS-CoV-2 genomes were obtained from April 2020 to January 2022. We report variants of concern (VOC) and interest (VOI) dynamics and the role of Brazilian lineages. We identified three World Health Organization VOCs (Gamma, Delta, Omicron) and one VOI (Zeta), which caused distinct waves in this cohort. We also identified 47 distinct Pango lineages. Consistent with the high prevalence of Gamma in Brazil, Pango lineage P.1 dominated infections in this cohort for half of 2021. Each wave of infection largely consisted of a single variant group, with each new group quickly and completely rising to dominance. Despite increasing vaccination in Brazil starting in 2021, this pattern was observed throughout the study and is consistent with the hypothesis that herd immunity tends to be SARS-CoV-2 variant-specific and does not broadly protect against COVID-19.

Efficacy and safety of Ixekizumab vs. low-dose IL-2 vs. Colchicine vs. standard of care in the treatment of patients hospitalized with moderate-to-critical COVID-19: A pilot randomized clinical trial (STRUCK: Survival Trial Using Cytokine Inhibitors).

BACKGROUND: Cases of coronavirus disease 2019 (COVID-19) requiring hospitalization continue to appear in vulnerable populations, highlighting the importance of novel treatments. The hyperinflammatory response underlies the severity of the disease, and targeting this pathway may be useful. Herein, we tested whether immunomodulation focusing on interleukin (IL)-6, IL-17, and IL-2, could improve the clinical outcomes of patients admitted with COVID-19. METHODS: This multicenter, open-label, prospective, randomized controlled trial was conducted in Brazil. Sixty hospitalized patients with moderate-to-critical COVID-19 received in addition to standard of care (SOC): IL-17 inhibitor (ixekizumab 80 mg SC/week) 1 dose every 4 weeks; low-dose IL-2 (1.5 million IU per day) for 7 days or until discharge; or indirect IL-6 inhibitor (colchicine) orally (0.5 mg) every 8 hours for 3 days, followed by 4 weeks at 0.5 mg 2x/day; or SOC alone. The primary outcome was accessed in the "per protocol" population as the proportion of patients with clinical improvement, defined as a decrease greater or equal to two points on the World Health Organization's (WHO) seven-category ordinal scale by day 28. RESULTS: All treatments were safe, and the efficacy outcomes did not differ significantly from those of SOC. Interestingly, in the colchicine group, all participants had an improvement of greater or equal to two points on the WHO seven-category ordinal scale and no deaths or patient deterioration were observed. CONCLUSIONS: Ixekizumab, colchicine, and IL-2 were demonstrated to be safe but ineffective for COVID-19 treatment. These results must be interpreted cautiously because of the limited sample size.

Does ascitic fluid filtration improve the microbiological diagnosis of spontaneous bacterial peritonitis? An experimental laboratory study / A filtração do líquido ascítico melhora o diagnóstico microbiológico da peritonite bacteriana espontânea? Um estudo experimental laboratorial

Background: Spontaneous Bacterial Peritonitis (SBP) is a serious and frequent complication among cirrhotic patients with ascites and can be diagnosed by cytological analysis of the ascitic fluid. The microbiological culture of ascitic fluid, however, is positive in less than 40% of SBP cases, which often results in inappropriate antimicrobial therapy. Empirical therapy may be suboptimal, increasing patient's risk of aggravation, or overestimated, unnecessarily boosting bacterial resistance. Objective: This experimental laboratory study aimed to standardize and verify the technical feasibility of ascitic fluid vacuum filtration, as a way to optimize the etiological diagnosis of SBP, compared to the automated method. Method: The method evaluated and standardized in this study was ascitic fluid vacuum filtration. Its principle is the concentration of bacteria on a filter membrane. Results: This study included 36 cirrhotic patients treated at a public university hospital between 11.13.2017 and 06.30.2019. Among them, 47.2% (17/36) presented cytology test results compatible with SBP. For these patients, culture sensitivity using the automated method was 35.3% (6/17), against 11.8% (2/17) with the vacuum filtration method. Conclusion: In conclusion, vacuum filtration does not improve the microbiological diagnosis of SBP in this population compared to the automated method (AU)

Contexto: A Peritonite Bacteriana Espontânea (PBE) é uma complicação grave e frequente entre pacientes cirróticos com ascite, diagnosticada por meio da análise citológica do líquido ascítico. A cultura microbiológica do líquido ascítico, por sua vez, é positiva em menos de 40% dos casos de PBE, o que resulta frequentemente na instituição de terapia antimicrobiana inapropriada. A terapia empírica pode ser subótima, aumentando o risco de agravamento do paciente, ou superestimada, impulsionando desnecessariamente a resistência bacteriana. Objetivo: Estudo experimental laboratorial, propôs padronizar e verificar a viabilidade técnica da filtração a vácuo do líquido ascítico, como forma de otimizar o diagnóstico etiológico na PBE, comparativamente ao sistema automatizado de culturas de sangue. Método: O método avaliado e padronizado neste estudo foi a da filtragem a vácuo do líquido ascítico. Esse tem como princípio a concentração da bactéria em uma membrana filtrante. Resultados: Nesse estudo, foram incluídos 36 pacientes cirróticos atendidos em um hospital público universitário, entre 13.11.2017 e 30.06.2019. Entre eles, 47,2% (17/36) apresentaram citologia compatível com PBE. Nesses, a sensibilidade da cultura pelo método semi-automatizado foi de 35,3% (6/17) e da cultura pelo método da filtragem a vácuo foi de 11,8% (2/17). Conclusão: Em conclusão, a filtragem a vácuo não melhora o diagnóstico microbiológico da PBE em relação ao método automatizado (AU)

Potential cannabidiol (CBD) repurposing as antibacterial and promising therapy of CBD plus polymyxin B (PB) against PB-resistant gram-negative bacilli.

This study aimed to assess the ultrapure cannabidiol (CBD) antibacterial activity and to investigate the antibacterial activity of the combination CBD + polymyxin B (PB) against Gram-negative (GN) bacteria, including PB-resistant Gram-negative bacilli (GNB). We used the standard broth microdilution method, checkerboard assay, and time-kill assay. CBD exhibited antibacterial activity against Gram-positive bacteria, lipooligosaccharide (LOS)-expressing GN diplococcus (GND) (Neisseria gonorrhoeae, Neisseria meningitidis, Moraxella catarrhalis), and Mycobacterium tuberculosis, but not against GNB. For most of the GNB studied, our results showed that low concentrations of PB (≤ 2 µg/mL) allow CBD (≤ 4 µg/mL) to exert antibacterial activity against GNB (e.g., Klebsiella pneumoniae, Escherichia coli, Acinetobacter baumannii), including PB-resistant GNB. CBD + PB also showed additive and/or synergistic effect against LOS-expressing GND. Time-kill assays results showed that the combination CBD + PB leads to a greater reduction in the number of colony forming units per milliliter compared to CBD and PB alone, at the same concentration used in combination, and the combination CBD + PB was synergistic for all four PB-resistant K. pneumoniae isolates evaluated. Our results show that CBD has translational potential and should be further explored as a repurposed antibacterial agent in clinical trials. The antibacterial efficacy of the combination CBD + PB against multidrug-resistant and extensively drug-resistant GNB, especially PB-resistant K. pneumoniae, is particularly promising.

Impact of a dental care intervention on the hospital mortality of critically ill patients admitted to intensive care units: A quasi-experimental study.

BACKGROUND: We aimed to evaluate the impact of providing dental care to critically ill patients on their risk of death and ventilator-associated pneumonia (VAP). METHODS: A quasi-experimental study was conducted in 2 intensive care units (ICU) from 2016 to 2019. The intervention consisted of implementing routine dental care, focusing on oral hygiene and periodontal treatment, at least 3 times a week, for patients admitted to the study units. In the pre-intervention period, routine oral hygiene was provided by the ICU nursing staff. The primary and secondary study outcomes were mortality, evaluated at the end of the ICU stay, and VAP incidence density, respectively. Data were analyzed using the ARIMA (autoregressive integrated moving average) time series model in R software. RESULTS: During the intervention period, 5,147 dental procedures were performed among 355 patients. The time series showed that ICU mortality was 36.11%, 32.71%, and 32.30% within the 3 years before the intervention, and 28.71% during the intervention period (P = .015). VAP incidence density did not significantly change during the study period (P = .716). CONCLUSION: A dental care intervention focused on oral hygiene and periodontal treatment regularly provided by dentists to critically ill patients may decrease their risk of dying in the ICU. Randomized clinical trials should be performed to confirm these findings. TRIAL REGISTRATION: WHO-affiliated Brazilian Clinical Trials Registry. RBR-4jmz36.

Comparing surgeons' skin tolerance and acceptability to alcohol-based surgical hand preparation vs traditional surgical scrub: A matched quasi-experimental study.

BACKGROUND: We aimed to compare the tolerance and acceptability of alcohol-based surgical hand preparation versus handscrubbing with antimicrobial soap and water by surgeons. METHODS: Matched quasi-experimental trial in an academic quaternary care hospital in Ribeirão Preto, Brazil, from April 1 to October, 31, 2017. Participants were cardiac and orthopedics surgeons from the study facility. In the first study phase, they performed handscrubbing with either 2% chlorhexidine (CHG) or 10% iodopovidone (PVP-I) and, in the second phase, they performed handrubbing with alcohol-based handrub (ABHR). Surgeons' skin tolerance and acceptability were evaluated using WHO-validated tools. Data were analyzed using the MacNemar's test within STATA. RESULTS: A total of 33 surgeons participated to the "per protocol" population; the majority were male (94%); mean age of 35 years (SD, 8.5). On product tolerance, there was a minimal variation in redness, scaliness, fissures, and visual evaluation of the skin when handrubbing with ABHR was compared to handscrubbing with either PVP-I or CHX. Regarding acceptability, participants rated better handrubbing with ABHR than handscrubbing with PVP-I when assessing product smell (66.6% vs 0%, p=0.002), color (73.3% vs 0%, p=0.001), product texture (60% vs 0%, p=0.004), skin dryness (60% vs 0%, p=0.004), ease of application (66.6% vs 0%, p=0.002) and overall satisfaction (66.6% vs 6.7% p=0.011). Participants rated similarly handrubbing with ABHR and handscrubbing with CHX, except for product texture, where handrubbing rated better (71,4% vs. 0%, p=0.002). Handrubbing with ABHR was preferred by 73.3%. CONCLUSION: Although handrubbing and handscrubbing were equally well tolerated by surgeons, alcohol-based surgical hand preparation fell into the personal preference for most of them.

Long-Term Symptoms among COVID-19 Survivors in Prospective Cohort Study, Brazil.

We conducted a prospective cohort study in a population with diverse ethnic backgrounds from Brazil to assess clinically meaningful symptoms after surviving coronavirus disease. For most of the 175 patients in the study, clinically meaningful symptoms, including fatigue, dyspnea, cough, headache, and muscle weakness, persisted for >120 days after disease onset.

Assessment of preauthorization and 24-hour expert consultation as a restrictive antimicrobial stewardship bundle in a Brazilian tertiary-care hospital: an interrupted time series analysis.

BACKGROUND: Worldwide, healthcare facilities face high and often inappropriate consumption of antimicrobials. However, there are limited antimicrobial stewardship (ASP) studies from low- and middle-income countries that include restrictive measures and their impacts on antimicrobial consumption. AIM: This study aims to assess the impact of a restrictive bundle (preauthorization requirements and offering consultation with an infectious diseases physician 24 hours a day) on antimicrobial consumption, in a tertiary hospital in Brazil. METHODS: We conducted an interrupted time series analysis (ITS) with pharmacy-based data from January 2010 to December 2018 to evaluate changes of level and slope in antimicrobial consumption (expressed in DDD/1,000 patient-days) after the implementation of the restrictive bundle in September 2014. Fourteen restricted antimicrobials (amphotericin B deoxycholate, liposomal amphotericin B, micafungin, voriconazole, ganciclovir, amikacin, ampicillin/sulbactam, daptomycin, ertapenem, levofloxacin, linezolid, piperacillin/tazobactam, polymyxin B, and tigecycline) and eight unrestricted were analysed. FINDINGS: Among the 14 restricted antimicrobials, four presented a significant negative level change: micafungin (-2,14, p=.027), voriconazole (-14.72, p<.001), ertapenem (-1.89, p=.007) and amikacin (-13.98, p<.001). The only negative slope change was observed for the liposomal amphotericin B, -0.532 (p=.009). The restricted antibiotics group presented an increased consumption trend (1.068, p=.002) compared to the pre-intervention period, a similar change was observed for the unrestricted antibiotics group (1.360, p<.001). CONCLUSION: Preauthorization and 24 hour expert consultation were partially effective as a restrictive antimicrobial stewardship bundle in a Brazilian tertiary-care hospital. Increased consumption of unrestricted antimicrobials was observed as a side effect of the intervention.
