Abstract
Treating bacteremia caused by antibiotic-resistant bacteria is a global concern. Antibacterial photodynamic inactivation is a promising strategy to combat it. However, it's challenging to achieve the inactivation of antibiotic-resistant bacteria in whole blood because of its opacity and complexity. We investigated a riboflavin photodynamic method to effectively inactivate antibiotic-resistant bacteria in whole blood. Four strains of antibiotic-resistant bacteria were isolated, identified, and cultured in this research: methicillin-resistant Staphylococcus aureus (MRSA), pan-drug-resistant Acinetobacter baumannii (PDRAB), ESBLs-producing Escherichia coli (EPEC) and pan-drug-resistant Klebsiella pneumoniae (PDRKP). To simulate bacteremia, antibiotic-resistant bacteria was added into whole blood. Whole blood was treated using riboflavin photodynamic method with ultraviolet irradiation (308 nm and 365 nm). The ultraviolet irradiation dose was divided into 18 J/cm2, 36 J/cm2, and 54 J/cm2. Microbial count of antibiotic-resistant bacteria in whole blood was used for evaluating inactivation effectiveness. The roles of red blood cells, lymphocytes, coagulation factors, and platelets in whole blood were assessed. In results, inactivation effectiveness increased as the ultraviolet dose increased from 18 J/cm2 to 54 J/cm2. At the dose of 18 J/cm2, inactivation effectiveness of four antibiotic-resistant bacteria were more than 80%, while only 67% of MRSA. The antibacterial effect was enhanced by the combination of riboflavin photodynamic treatment and antibiotic. The red blood cell function was susceptible to ultraviolet dose. At the dose of 18 J/cm2, hemolysis rate was less than 0.8% and there was no change in levels of ATP and 2,3-DPG. At the same dose, the proliferation, cell killing, and cytokine secretion activities of lymphocytes decreased 20-70%; Factor V and Factor VIII activities decreased 50%; Fibrinogen and platelet function loss significantly but reparable. Consequently, we speculated that riboflavin photodynamic method with a ultraviolet dose of 18 J/cm2 was effective in inactivating four antibiotic-resistant bacteria in whole blood while whole blood function was preserved. We also provided a novel extracorporeal circulation phototherapy mode for treating bacteremia caused by antibiotic-resistant bacteria.

The Association Between Duration of Antibiotics and Infectious Complications Following Radical Cystectomy: Analysis of the 2019-2021 NSQIP Database. Urology 2024; 189:64-69. [PMID: 38648953 DOI: 10.1016/j.urology.2024.04.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 03/21/2024] [Accepted: 04/09/2024] [Indexed: 04/25/2024]
Abstract
OBJECTIVES To identify the impact of the duration of peri-operative antibiotics on infectious complications following radical cystectomy. METHODS The National Surgical Quality Improvement Project (NSQIP) targeted database was queried for patients undergoing radical cystectomy from 2019 to 2021. Baseline patient characteristics were collected. Antibiotic duration was classified as <24 hours (short), 24-72 hours (intermediate) or >72 hours (long). Infectious complication data were collected including surgical site infection (SSI), urinary tract infection (UTI), organ space infection, pneumonia, sepsis, and clostridium difficile infection up to 30 days after surgery. Univariate and multivariable analyses were performed to compare duration of antibiotic therapy to infectious outcomes. RESULTS Of the 4363 patients who underwent radical cystectomy, 3250 (74%), 827 (19%) and 286 (6.6%) received short, intermediate, and long duration of peri-operative antibiotics, respectively. Infectious complication occurred in 954 (22%) patients, including 227 (5.2%) SSI, 280 (6.4%) UTI, 268(6.1%) organ space infection, 87 (2%) pneumonia, and 378 (8.7%) sepsis. Clostridium difficile infection occurred in 89 (2%) patients. On multivariable analysis, there was no significant difference in overall infectious complication rates with long-duration antibiotics. However, intermediate duration of antibiotics in open surgery was associated with a decreased risk of SSI (OR 0.58; 95%CI 0.37-0.91) compared to those treated with short-term antibiotics. CONCLUSION Despite guideline recommendations, 26% of patients in this database received >24 hours of peri-operative antibiotics without decreased risk of overall infectious complication. An intermediate course of antibiotics decreased risk of SSI in open surgery compared to the guideline recommend <24-hour course. Greater education regarding antibiotic stewardship and further studies investigating infectious complications are warranted.

Gut diversity and the resistome as biomarkers of febrile neutropenia outcome in paediatric oncology patients undergoing hematopoietic stem cell transplantation. Sci Rep 2024; 14:5504. [PMID: 38448687 PMCID: PMC10918076 DOI: 10.1038/s41598-024-56242-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 03/04/2024] [Indexed: 03/08/2024] Open
Abstract
The gut microbiota of paediatric oncology patients undergoing a conditioning regimen before hematopoietic stem cell transplantation is recently considered to play role in febrile neutropenia. Disruption of commensal microbiota and evolution of opportune pathogens community carrying a plethora of antibiotic-resistance genes play crucial role. However, the impact, predictive role and association of patient´s gut resistome in the course of the therapy is still to be elucidated. We analysed gut microbiota composition and resistome of 18 paediatric oncology patients undergoing hematopoietic stem cell transplantation, including 12 patients developing febrile neutropenia, hospitalized at The Bone Marrow Transplantation Unit of the National Institute of Children´s disease in Slovak Republic and healthy individuals (n = 14). Gut microbiome of stool samples obtained in 3 time points, before hematopoietic stem cell transplantation (n = 16), one week after hematopoietic stem cell transplantation (n = 16) and four weeks after hematopoietic stem cell transplantation (n = 14) was investigated using shotgun metagenome sequencing and bioinformatical analysis. We identified significant decrease in alpha-diversity and nine antibiotic-resistance genes msr(C), dfrG, erm(T), VanHAX, erm(B), aac(6)-aph(2), aph(3)-III, ant(6)-Ia and aac(6)-Ii, one week after hematopoietic stem cell transplantation associated with febrile neutropenia. Multidrug-resistant opportune pathogens of ESKAPE, Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli found in the gut carried the significant subset of patient's resistome. Over 50% of patients treated with trimethoprim/sulfamethoxazole, piperacillin/tazobactam and amikacin carried antibiotic-resistance genes to applied treatment. The alpha diversity and the resistome of gut microbiota one week after hematopoietic stem cell transplantation is relevant predictor of febrile neutropenia outcome after hematopoietic stem cell transplantation. Furthermore, the interindividual diversity of multi-drug resistant opportunistic pathogens with variable portfolios of antibiotic-resistance genes indicates necessity of preventive, personalized approach.

Abstract
BACKGROUND Periprocedural prophylaxis in medicine encompasses the set of measures (physical, chemical, and pharmacological) used to reduce the risk of infection. Antibiotic prophylaxis (AP) refers to the administration of a short-term regimen of antibiotics shortly before a medical procedure to reduce the risk of infectious complications that can result from diagnostic and therapeutic interventions. The outspreading growth of multidrug-resistant bacterial species and changes in the bacterial local ecosystem have impeded the development of a unique scheme of AP in urology. OBJECTIVES To review the literature and current guidelines regarding AP for urological diagnostic and therapeutic procedures, and to define agents, timing, and occasions when administering pharmacological prophylaxis. Secondly, according to current literature, to open new scenarios where AP can be useful or useless. RESULTS Major gaps in evidence still exist in this field. AP appears useful in many invasive procedures and some sub-populations at risk of infectious complications. AP is not routinely recommended for urodynamic exams, diagnostic cystoscopy, and extracorporeal shock-wave lithotripsy. The available data regarding the use of AP during the transperineal prostate biopsy are still unclear; conversely, in the case of the transrectal approach AP is mandatory. AP is still considered the gold standard for the prevention of postoperative infective complications in the case of ureteroscopy, percutaneous nephrolithotomy, endoscopic resection of bladder tumor, endoscopic resection of the prostate, and prosthetic or major surgery. CONCLUSION The review highlights the complexity of determining the appropriate candidates for AP, emphasizing the importance of considering patient-specific factors such as comorbidities, immunocompetence, and the nature of the urologic intervention. The evidence suggests that a one-size-fits-all approach may not be suitable, and a tailored strategy based on the specific procedure and patient characteristics is essential.

Abstract
BACKGROUND Antimicrobial stewardship (AMS) guidelines advocate for the use of antibiograms (cumulative antimicrobial susceptibility test data) as a tool to guide empirical antibiotic prescribing and inform local treatment guidelines. The objective of this review is to evaluate the effectiveness of antibiograms as an intervention to optimize antimicrobial prescribing and patient outcomes. METHODS Embase, PubMed, CINAHL, and International Pharmacy Abstracts (IPA) databases were searched from inception until September 2022, to identify studies of antibiogram-related interventions in all health care settings. The National Institutes of Health Quality Assessment Tools were used to assess the methodological quality of the included studies. RESULTS Of the 37 included studies, the majority of studies were conducted in the United States (n = 25) and in hospital settings (n = 27). All interventions were multifaceted and in 26 (70%) studies, facility-specific antibiograms could be considered as an integral component of the interventions. A positive impact on antibiotic consumption trends (17 studies), appropriateness of prescribing (16 studies), and cost of treatment (6 studies) was found, with minimal evidence for improvement in mortality, hospitalization, and resistance profiles. Due to the heterogeneity in study designs and outcomes, a meta-analysis was not performed. CONCLUSIONS AMS interventions including antibiograms may improve antibiotic use, appropriateness, and costs. Multifaceted interventions were often used, which precludes drawing conclusions about the effectiveness of antibiograms alone as an AMS tool.

Abstract
Treatments for acute respiratory distress syndrome are still unavailable, and the prevalence of the disease has only increased due to the COVID-19 pandemic. Mechanical ventilation regimens are still utilized to support declining lung function but also contribute to lung damage and increase the risk for bacterial infection. The anti-inflammatory and pro-regenerative abilities of mesenchymal stromal cells (MSCs) have shown to be a promising therapy for ARDS. We propose to utilize the regenerative effects of MSCs and the extracellular matrix (ECM) in a nanoparticle. Our mouse MSC (MMSC) ECM nanoparticles were characterized using size, zeta potential, and mass spectrometry to evaluate their potential as pro-regenerative and antimicrobial treatments. The nanoparticles had an average size of 273.4 nm (±25.6) and possessed a negative zeta potential, allowing them to surpass defenses and reach the distal regions of the lung. It was found that the MMSC ECM nanoparticles are biocompatible with mouse lung epithelial cells and MMSCs, increasing the wound healing rate of human lung fibroblasts while also inhibiting the growth of Pseudomonas aeruginosa, a common lung pathogen. Our MMSC ECM nanoparticles display characteristics of healing injured lungs while preventing bacterial infection, which can increase recovery time.

Abstract
The oral cavity is home to diverse microbial content, collectively called as the oral microbiome. The latest technological advancements have unraveled the intricacies of the oral microbiome. It can be of great importance for oral health care givers to know the fundamentals and latest developments in the field of the oral microbiome, as oral dysbiosis is associated with many common diseases frequently seen and managed by them. These diseases include dental caries, periodontitis, mucosal diseases (such as oral leukoplakia, oral lichen planus, and systemic lupus erythematosus), oral cancers, and even co-infections related to the current COVID-19 pandemic. The emergence of new genomic and molecular biology methodologies has been pivotal for understanding the role of the human microbiome in health and disease. The current review compiles oral microbiome in health and disease with a multidisciplinary dental approach. The insight into the oral microbiome, which is provided dental specialty wise in the current article will initiate and guide researchers of various disciplines in developing microbiome-based therapeutic or prophylactic management strategies, managing public health challenges by microbiome-based boarder interventions and divert resources for preserving and achieving a balanced oral microbiome.

Re-examining advice to complete antibiotic courses: a qualitative study with clinicians and patients. BJGP Open 2023:BJGPO.2022.0170.

Abstract
BACKGROUND Antibiotic treatment duration may be longer than sometimes needed. Stopping antibiotics early, rather than completing pre-set antibiotic courses, may help reduce unnecessary exposure to antibiotics and antimicrobial resistance (AMR). AIM To identify clinicians' and patients' views on stopping antibiotics when better (SAWB) for urinary tract infections (UTIs), and to explore comparisons with other acute infections. DESIGN & SETTING An exploratory qualitative study with general practice clinicians and patients in England. METHOD Primary care clinicians and patients who had recent UTI experience were recruited in England. Remote one-to-one interviews with clinicians and patients, and one focus group with patients, were conducted. Data were audiorecorded, transcribed, and analysed thematically. RESULTS Eleven clinicians (seven GPs) and 19 patients (14 with experience of recurrent and/or chronic UTIs) were included. All participants considered SAWB unfamiliar and contradictory to well-known advice to complete antibiotic courses, but were interested in the evidence for risks and benefits of SAWB. Clinicians were amenable if evidence and guidelines supported it, whereas patients were more averse because of concerns about the risk of UTI recurrence and/or complications and AMR. Participants viewed SAWB as potentially more appropriate for longer antibiotic courses and other infections (with longer courses and lower risk of recurrence and/or complications). Participants stressed the need for unambiguous advice and SAWB as part of shared decision making and personalised advice. CONCLUSION Patients were less accepting of SAWB, whereas clinicians were more amenable to it. Patients and clinicians require good evidence that this novel approach to self-determining antibiotic duration is safe and beneficial. If evidence based, SAWB should be offered with an explanation of why the advice differs from the 'complete the course' instruction, and a clear indication of when exactly to stop antibiotics should be given.

Abstract
BACKGROUND Viruses are associated with pediatric community-acquired pneumonia (CAP) but are also common in the upper airways of healthy children. We have determined the contribution of respiratory viruses and bacteria by comparing children with CAP and hospital controls. METHODS Children less than 16 years old with radiologically confirmed CAP (n = 715) were enrolled over an 11-year period. Children admitted for elective surgery during the same period served as controls (n = 673). Nasopharyngeal aspirates were tested for 20 respiratory pathogens by semiquantitative polymerase chain reaction tests and cultivated for bacteria and viruses. We used logistic regression to calculate adjusted odds ratios [aOR; 95% confidence intervals (CIs)], and estimated population-attributable fractions (95% CI). RESULTS At least 1 virus was detected in 85% of cases and 76% of controls, and greater than or equal to 1 bacterium was detected in 70% of cases and controls. The presence of respiratory syncytial virus (RSV) (aOR, 16.6; 95% CI: 9.81-28.2), human metapneumovirus (HMPV) (13.0; 6.17-27.5) and Mycoplasma pneumonia e (27.7; 8.37-91.6) were most strongly associated with CAP. For RSV and HMPV, there were significant trends between lower cycle-threshold values indicating higher viral genomic loads, and higher aORs for CAP. The population-attributable fraction estimates of RSV, HMPV, human parainfluenza virus, influenza virus and M. pneumoniae were 33.3% (32.2-34.5), 11.2% (10.5-11.9), 3.7% (1.0-6.3), 2.3% (1.0-3.6) and 4.2% (4.1-4.4), respectively. CONCLUSIONS RSV, HMPV and M. pneumoniae were most strongly related to pediatric CAP and accounted for half of all cases. There were positive trends between increasing viral genomic loads of RSV and HMPV, and higher odds for CAP.

Abstract
BACKGROUND Antibiotic resistance is an individual and public health problem; multidrug-resistant infections could cause an estimated 10 million deaths worldwide by 2050. Unnecessary use of antimicrobials is the most important cause of resistance generation in the community, and an estimated 80% of antimicrobials are prescribed in primary health care, frequently for urinary tract infections (UTIs). OBJECTIVE This paper presents the protocol for the first phase of the Urinary Tract Infections in Catalonia (Infeccions del tracte urinari a Catalunya) project. We aim to examine the epidemiology of the different types of UTIs in Catalonia (an autonomous community in Spain) and their diagnostic and therapeutic management by health professionals. Furthermore, we aim to evaluate the correlation between types and total consumption of antibiotics for recurrent UTIs in 2 cohorts of women with the presence and severity of infectious complications of urological origin, especially pyelonephritis and sepsis, and 2 potentially serious infections: pneumonia and COVID-19. METHODS The study is a population-based observational cohort study including adults with a diagnosis of UTI registered in the Information System for the Development of Research in Primary Care (in Catalan: Sistema d'informació per al desenvolupament de la investigació en atenció primària), the Minimum Basic Data Sets of Hospital Discharges and Emergency Departments (in Catalan: Conjunt mínim bàsic de dades a l'hospitalització d'aguts i d'atenció urgent), and data from the Hospital Dispensing Medicines Register (in Catalan: Medicació hospitalària de dispensació ambulatòria) of Catalonia from the period between 2012 and 2021. We will evaluate the variables obtained from the databases to analyze the proportion of different types of UTIs, the percentage of adequate antibiotic treatments prescribed or received for recurrent UTIs according to the national guidelines, and the proportion of UTIs with complications. RESULTS We expect to describe the epidemiology of UTIs in Catalonia from 2012 to 2021, as well as describe the diagnostic and therapeutic management of UTIs by health professionals. CONCLUSIONS We expect to find a high percentage of UTI cases with inadequate management according to the national guidelines, considering that on many occasions UTIs are treated with second- or third-line antibiotic therapies with a preference for the longest regimens. Furthermore, the use of antibiotic suppressive therapies, or prophylaxis, in recurrent UTIs will likely be highly variable. Moreover, we aim to determine whether women with recurrent UTIs treated with antibiotic suppressive therapies have a higher incidence and severity of potentially serious future infections, with special attention to acute pyelonephritis, urosepsis, COVID-19, and pneumonia, compared to women who receive antibiotic treatment after they present with a UTI. This is an observational study of data from administrative databases that will not allow causality analysis. The limitations of the study will be handled according to the appropriate statistical methods.

Abstract
This manuscript presents the cytotoxicity, antimicrobial activity, antibiofilm preliminary properties, and associated therapy with commercial drugs using water-soluble tetra-cationic porphyrins against Pseudomonas aeruginosa. Two commercial tetra-cationic porphyrins were tested against a standard strain of P. aeruginosa 01 (PA01) in antibacterial activity assays under dark conditions and irradiated with white light for 120 min. Porphyrin 4-H2TMePor showed better antimicrobial activity and was chosen for further tests. Increased minimum inhibitory concentration was observed in the presence of reactive oxygen species, suggesting that photooxidation was mediated by the singlet oxygen production. In the time-kill curve assay, 4-H2TMePor inhibited bacterial growth in 90 min of irradiation. The checkerboard assay revealed synergistic interactions. Biofilms of the standard PA01 strain and three clinical isolates were formed. The biofilm destruction assay was more efficient for PA01, significantly reducing the biofilm biomass formed compared to the positive control. The associated treatment to destroy the biofilm potentiated a significant decrease in the biofilm biomass compared to the positive control. The photosensitizer did not damage human keratinocytes or mouse fibroblasts in the cytotoxicity assays, demonstrating the safety of using 4-H2TMePor. Atomic force microscopy indicated lower adhesion force, higher cell wall deformation, and higher dissipation energy in the treated control compared to untreated PA01. Given our findings, it is evident that water-soluble tetra-cationic porphyrins have excellent antimicrobial and a preliminary antibiofilm activity against Gram-negative bacteria, proving to be a potential photosensitizer for clinical use.

Abstract
Intraabdominal abscess formation occurs in up to 30% of patients suffering from Crohn´s disease (CD). While international guidelines recommend a step-up approach with a combination of empiric antibiotic therapy and percutaneous drainage to delay or even avoid surgery, evidence about microbial spectrum in penetrating ileitis is sparse. We retrospectively assessed outcomes of 46 patients with terminal penetrating Ileitis where microbial diagnostics have been performed and compared microbial spectrum and antibiotic resistance profile of CD patients with patients suffering from diverticulitis with intraabdominal abscess formation. In both groups, the most frequently isolated pathogen was the gram-negative bacterium E. coli belonging to the family of Enterobacterales. However, overall Enterobacterales were significantly more often verifiable in the control group than in CD patients. Furthermore, microbial analysis showed significant differences regarding isolation of anaerobic pathogens with decreased frequency in patients with CD. Subgroup analysis of CD patients to evaluate a potential influence of immunosuppressive therapy on microbial spectrum only revealed that Enterobacterales was less frequently detected in patients treated with steroids. Immunosuppressive therapy did not show any impact on all other groups of pathogens and did not change antibiotic resistance profile of CD patients. In conclusion, we were able to demonstrate that the microbial spectrum of CD patients does differ only for some pathogen species without increased rate of antibiotic resistance. However, the empiric antibiotic therapy for CD-associated intra-abdominal abscess remains challenging since different points such as local epidemiological and microbiological data, individual patient risk factors, severity of infection, and therapy algorithm including non-surgical and surgical therapy options should be considered before therapeutical decisions are made.

Abstract
Antimicrobial resistance (AMR) can complicate effective management of urinary tract infections. We conducted a retrospective study of AMR in Enterobacterales urine isolates from ambulatory and hospitalized adult patients from 2018-2020 (BD Insights Research Database) to evaluate regional differences in isolates with an extended-spectrum beta-lactamase-producing phenotype and those not susceptible to beta-lactams, fluoroquinolone (FQ), nitrofurantoin (NFT), trimethoprim/sulfamethoxazole (TMP/SMX), or multiple antibiotic classes (≥ 2 or ≥ 3). Our analyses included 349,741 Enterobacterales urine isolates from 321 inpatient facilities and 980,354 isolates from 338 ambulatory care facilities. In multivariable analyses, the highest rate of resistance was to beta-lactams (60.8% and 55.8% for inpatient and ambulatory settings, respectively), followed by FQ (27.5%), NFT (27.0%), and TMP/SMX (25.4%) for inpatients and by TMP/SMX (22.4%), FQ (21.6%), and NFT (21.6%) for ambulatory patients. Isolates with an extended-spectrum beta-lactamase-producing phenotype (13.2% and 8.6% for inpatient and ambulatory settings, respectively) and multidrug resistance (inpatient and ambulatory rates of 23.4% and 17.7% for ≥ 2 drugs; 9.9% and 6.4% for ≥ 3 drugs) were also prevalent. Statistically significant differences by geographic region (P ≤ 0.005) were observed for AMR classes in both inpatient and ambulatory settings, but the rates remained above the thresholds recommended for empiric urinary tract infection therapy across most regions.

Abstract
BACKGROUND The introduction of antibiotics has significantly reduced morbidity and mortality from microbial infections, but the rise of antibiotic-resistant and multidrug-resistant microbes is of increasing clinical concern. Few studies have examined the prevalence and impact of antibiotic resistance in common antenatal infections. OBJECTIVE This study aimed to determine whether pregnant women with a urine culture positive for antibiotic-resistant or multidrug-resistant gram-negative bacteria are at increased risk of developing pyelonephritis than pregnant women infected with antibiotic-susceptible organisms. STUDY DESIGN This was a retrospective cohort study of pregnant women with asymptomatic bacteriuria or acute cystitis from a single health system from July 2013 to May 2019. Women with gram-negative antibiotic-resistant (resistance to 1-2 antibiotic classes) and multidrug-resistant (resistance to ≥3 antibiotic classes) lower urinary tract infections were compared with women with antibiotic-susceptible urinary tract infections in terms of demographic, infectious, antepartum, and intrapartum data. The primary outcome was pyelonephritis, defined as a billing code for pyelonephritis plus fever or flank pain. The secondary outcomes were length of stay in the hospital because of pyelonephritis, a composite of pyelonephritis complications (renal abscess, sepsis, and intensive care unit admission), and preterm delivery. The differences in the primary outcome were analyzed using multivariate logistic regression. RESULTS A total of 573 women were eligible for inclusion. Of the 573 women, 334 (58%) had gram-negative bacteria on urine culture. Of the 334 cases, 173 (52%) were antibiotic susceptible, 74 (22%) were antibiotic resistant, and 87 (26%) were multidrug resistant. Women with antibiotic-resistant and multidrug-resistant infections were more likely to have hypertension (P=.004), to be Black (P=.03), to have public insurance (P=.002), and to experience more urinary infections (P=.001). Pyelonephritis was more common in women with antibiotic-resistant (adjusted odds ratio, 2.27; 95% confidence interval, 1.08-4.78) and multidrug-resistant (adjusted odds ratio, 3.06; 95% confidence interval, 1.57-5.96) infections than in women with antibiotic-susceptible urinary tract infections. Length of stay, preterm delivery, and pyelonephritis complications did not differ between antibiotic-susceptible and antibiotic-resistant and multidrug-resistant infections. CONCLUSION In an age of increasing antibiotic resistance, more than one-half of pregnant women with bacteriuria experience at least 1 infection with an antibiotic-resistant organism. These resistance patterns have a real clinical impact as pregnant women with antibiotic-resistant gram-negative lower urinary tract infections have an estimated 2- to 3-fold increased odds of developing pyelonephritis.

Abstract
BACKGROUND Urinary tract infections (UTIs), which are usually caused by bacteria in the Enterobacterales family, are a common reason for outpatient visits. Appropriate empiric therapy for UTIs requires an understanding of antibiotic resistance in the community. In this nationwide study, we examined trends in antibiotic resistance in urinary Enterobacterales isolates from ambulatory patients in the United States (US). METHODS We analyzed the antimicrobial susceptibility profiles (extended-spectrum beta-lactamase [ESBL]-producing phenotype and not susceptible [NS] to beta-lactams, trimethoprim/sulfamethoxazole [TMP/SMX], fluoroquinolones [FQ], or nitrofurantoin [NFT]) of 30-day non-duplicate Enterobacterales isolates from urine cultures tested at ambulatory centers in the BD Insights Research Database (2011-2020). The outcome of interest was the percentage of resistant isolates by pathogen and year. Multi-variable generalized estimating equation models were used to assess trends in resistance over time and by additional covariates. RESULTS A total of 338 US facilities provided data for > 2.2 million urinary Enterobacterales isolates during the 10-year study. Almost three-quarters (72.8%) of Enterobacterales isolates were Escherichia coli. Overall unadjusted resistance rates in Enterobacterales isolates were 57.5%, 23.1%, 20.6%, and 20.2% for beta-lactams, TMP/SMX, FQ, and NFT, respectively, and 6.9% had an ESBL-producing phenotype. Resistance to two or more antibiotic classes occurred in 16.4% of isolates and 5.5% were resistant to three or more classes. Among isolates with an ESBL-producing phenotype, 70.1%, 59.9%, and 33.5% were NS to FQ, TMP/SMX, and NFT, respectively. In multivariable models, ESBL-producing and NFT NS Enterobacterales isolates increased significantly (both P < 0.001), while other categories of resistance decreased. High rates (≥ 50%) of beta-lactam and NFT resistance were observed in Klebsiella isolates and in non-E. coli, non-Klebsiella Enterobacterales isolates. CONCLUSIONS Antimicrobial resistance was common in urinary Enterobacterales isolates. Isolates with an ESBL-producing phenotype increased by about 30% between 2011 and 2020, and significant increases were also observed in NFT NS Enterobacterales isolates. Resistance rates for all four antibiotic classes were higher than thresholds recommended for use as empiric therapy. Non-E. coli Enterobacterales isolates showed high levels of resistance to commonly used empiric antibiotics, including NFT. These data may help inform empiric therapy choices for outpatients with UTIs.

Abstract
INTRODUCTION Uncomplicated lower urinary tract infections (uLUTI) are a common problem in primary care. Current local guidelines recommend the use of a single 3 g dose of fosfomycin. However, most general practitioners (GP) prefer short-course therapies to single-dose therapy. No study has compared head-to-head short-course antimicrobial agents for uLUTIs. Therefore, the aim of this randomised clinical trial is to compare three different short-course antibiotic therapies with a single-dose of fosfomycin for these infections. METHODS AND ANALYSIS This will be a pragmatic, multicentre, parallel group, open trial. Women aged 18 or older and with symptoms of uLUTI and a positive urine dipstick analysis will be randomised to one of the following four groups: a single dose of 3 g of fosfomycin, 2 days of 3 g of fosfomycin o.d., 3 days of pivmecillinam 400 mg three times per day (t.i.d) or 5 days of nitrofurantoin 100 mg t.i.d. A total sample of 1120 patients was calculated. The primary endpoint is clinical effectiveness at day 7, defined as cure of symptoms reported by the patients in a diary including four symptoms: dysuria, urgency, frequency and suprapubic pain, which will be scored on a 4-point severity scale (not present/mild/moderate/severe). Follow-up visits are scheduled at days 7 (phone call), 14 and 28 for assessing evolution. Urine samples will be collected in the three on-site visits and urine cultures performed. If positive, antibiograms for the three antibiotics studied will be performed. Bacterial eradication will be measured at days 14 and 28. ETHICS AND DISSEMINATION The study was approved by the Ethical Board of IDIAP Jordi Gol (reference number: 21/173-AC) and Spanish Agency of Medicines and Medical Devices. The findings of this trial will be disseminated through research conferences and peer-review journals. TRIAL REGISTRATION NUMBER NCT04959331; EudraCT Number: 2021-001332-26. TIME SCHEDULE January 2022 to April 2023.

Abstract
Optimisation of antibiotic prescribing is critical to combat antimicrobial resistance. Point-of-care tests (POCTs) for common infections could be a valuable tool to achieve this in primary care. Currently, their use has primarily been studied in high-income countries. Trials in low-and-middle-income countries face challenges unique to their setting. This study aims to explore the barriers and facilitators for a future trial of POCTs for common infections in South Africa. Twenty-three primary care clinicians in the Western Cape Metropole were interviewed. Interview transcripts were analysed using thematic analysis. We identified three key themes. These themes focused on clinicians’ views about proposed trial design and novel POCTs, clinicians’ perspectives about trial set-up, and specific trial procedures. Participants were overall positive about the proposed trial and POCTs. Potential issues centred around the limited space and technology available and participant retention to follow-up. Additionally, impact on clinic workload was an important consideration. These insights will be invaluable in informing the design of a feasibility trial of POCTs in this setting.

Abstract
INTRODUCTION Reaching the point of treatment failure in the management of pediatric acute otitis media (AOM) is decision-changing, and is often associated with switching to a broader coverage antibiotic with/without middle ear surgical drainage. Yet, still there is no consensus on the definition of what is treatment failure, which may lead to confusion for clinical decision-making purposes. We sought to review the heterogeneity of treatment failure definitions in AOM. METHODS We searched for relevant English language manuscripts using the following key-words: ['otitis media' (OM) or (AOM)] AND ['treatment failure' or 'failure' or 'response failure' or 'response'] AND 'human' in various electronic databases from 1/1/2005 through 10/31/2020. RESULTS In the 60 retrieved papers, treatment failure was considered only when antibiotics had been prescribed beforehand, but not when watchful waiting had been adopted. We categorized the manuscripts into 5 major treatment failure definition subgroups, which occasionally overlapped: unimprovement or worsening of symptoms or signs of failure in otoscopy (n = 36), specialist(s) referral or hospital admission (n = 12), changing or adding antibiotic treatment (n = 22), failure to eradicate causative bacteria (n = 7) and failure as perceived by parents (n = 4). CONCLUSIONS We suggest a broader definition of AOM treatment failure including physical examination findings and degree of initial treatment response, which will enable an unbiased, uniform comparison of treatments for pediatric AOM.

Antibiotics (Basel) 2021; 10:antibiotics10080986. [PMID: 34439036 PMCID: PMC8389014 DOI: 10.3390/antibiotics10080986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Revised: 07/05/2021] [Accepted: 07/07/2021] [Indexed: 11/16/2022] Open
Abstract
Pharmacists play a key role in tackling antibiotic misuse through counseling and education of patients and healthcare providers. The study aim is to evaluate the appropriateness of antibiotic prescriptions in community pharmacy settings while implementing an interventional call-back service to assess adherence and symptom resolution among patients prescribed an antibiotic. Patients were recruited by community pharmacists who were assigned to either the call-back, structured counseling, or standard care arms. Patients in the call-back group received intensive antibiotic counseling and a phone call from the study pharmacist 3 to 5 days after antibiotic initiation. The counseling arm patients received intensive antibiotic counseling from the study pharmacist while patients in the standard care arm received routine care. Antibiotic adherence rates among the standard care (n = 25), counseling (n = 29), and call-back (n = 26) groups were 64%, 86.2%, and 88.5%, respectively (X2 = 5.862, p = 0.053). Symptom severity scores after completion of antibiotic treatment among all groups were rated as excellent. Twenty-nine percent of the outpatient antibiotic prescriptions were deemed as inappropriate. A pharmacist call-back service is a simple and inexpensive intervention which can effectively identify opportunities for improving appropriate antibiotic use, particularly with respect to adherence.

Abstract
BACKGROUND The high incidence of bacterial genes that confer resistance to last-resort antibiotics, such as colistin, caused by mobilized colistin resistance (mcr) genes, poses an unprecedented threat to human health. Understanding the spread, evolution, and distribution of such genes among human populations will help in the development of strategies to diminish their occurrence. To tackle this problem, we investigated the distribution and prevalence of potential mcr genes in the human gut microbiome using a set of bioinformatics tools to screen the Unified Human Gastrointestinal Genome (UHGG) collection for the presence, synteny and phylogeny of putative mcr genes, and co-located antibiotic resistance genes. RESULTS A total of 2079 antibiotic resistance genes (ARGs) were classified as mcr genes in 2046 metagenome assembled genomes (MAGs), distributed across 1596 individuals from 41 countries, of which 215 were identified in plasmidial contigs. The genera that presented the largest number of mcr-like genes were Suterella and Parasuterella. Other potential pathogens carrying mcr genes belonged to the genus Vibrio, Escherichia and Campylobacter. Finally, we identified a total of 22,746 ARGs belonging to 21 different classes in the same 2046 MAGs, suggesting multi-resistance potential in the corresponding bacterial strains, increasing the concern of ARGs impact in the clinical settings. CONCLUSION This study uncovers the diversity of mcr-like genes in the human gut microbiome. We demonstrated the cosmopolitan distribution of these genes in individuals worldwide and the co-presence of other antibiotic resistance genes, including Extended-spectrum Beta-Lactamases (ESBL). Also, we described mcr-like genes fused to a PAP2-like domain in S. wadsworthensis. These novel sequences increase our knowledge about the diversity and evolution of mcr-like genes. Future research should focus on activity, genetic mobility and a potential colistin resistance in the corresponding strains to experimentally validate those findings.

Abstract
BACKGROUND Acute otitis media (AOM) is a common cause for antibiotic prescription. Most guidelines endorse abstaining from immediate antibiotic treatment ('watchful waiting', WW) in mild-moderate episodes. We studied adherence rates to the latest AOM guidelines (2013), in terms of antibiotic type and prescription options. METHODS In this population-based study, AOM episodes were identified in Clalit Health Services-insured children aged 0-10 years between 2011 and 2018, using a data-sharing platform. After identifying the index, prescription and issuing dates for antibiotics for each AOM episode, treatment was categorized as immediate (≤2 days after diagnosis) or WW (antibiotic not prescribed/issued; prescribed ≤2 days after diagnosis but issued on Days 2-7; or prescribed/issued on Days 2-7). Guideline adherence was measured according to age. RESULTS Of the 491 106 episodes, 361 518 (73.6%) were treated with antibiotics. Following the 2013 guidelines, the ratio of episodes in children aged ≤6 months that were adherent (immediate treatment) was higher (OR = 1.22; 95% CI 1.15-1.29; P < 0.001), whereas the adherent episode ratio for children aged 6-24 months and 2-10 years (WW) was lower (OR = 0.87; 95% CI 0.85-0.88 and OR = 0.94; 95% CI 0.92-0.96, respectively; P < 0.001). Antibiotic prescription rates after 2013 for children aged ≤6 months were not different (OR = 1.03; 95% CI 0.96-1.1; P = 0.4), but were higher in children aged 6-24 months and 2-10 years (OR = 1.07; 95% CI 1.05-1.09; P < 0.001 and OR = 1.02; 95% CI 1.01-1.04; P = 0.015, respectively). Amoxicillin was the most common antibiotic, administered in 75.6% of episodes. Azithromycin was most commonly associated with treatment failure (6.6%). CONCLUSIONS Improved adherence to the 2013 guidelines was observed only in children aged ≤6 months and over-treatment with antibiotics was still high.

Abstract
Rapid diagnostic tests, which accurately distinguish bacterial from viral infections, are being heralded as the solution to antibiotic overuse, which is a key driver of antimicrobial resistance. We have concerns that this approach is oversimplistic. Rapid diagnostic tests are complex interventions, with clinical context, patient flow, access and timing affecting their impact. There is little robust evidence that they reduce antibiotic prescribing in real-world settings. We suggest that prior to introducing these costly tests, emphasis should be placed on optimizing the implementation of efficient evidence-based antimicrobial stewardship interventions, such as increasing the use of proven automated clinical infection syndrome prediction tools by clinicians, supporting patients to self-care by providing them with high-quality safety-netting resources, providing front-line clinicians with individual prescribing data to facilitate peer benchmarking and setting specific and purposeful antibiotic prescribing targets to improve the quality of antimicrobial prescribing. The stakes are high and time is running out; let's start by getting the basics right.

Antibiotic prescriptions and risk factors for antimicrobial resistance in patients hospitalized with urinary tract infection: a matched case-control study using the French health insurance database (SNDS). BMC Infect Dis 2021; 21:571. [PMID: 34126937 PMCID: PMC8201676 DOI: 10.1186/s12879-021-06287-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 05/27/2021] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Antibiotic resistance is increasing among urinary pathogens, resulting in worse clinical and economic outcomes. We analysed factors associated with antibiotic-resistant bacteria (ARB) in patients hospitalized for urinary tract infection, using the comprehensive French national claims database. METHODS Hospitalized urinary tract infections were identified from 2015 to 2017. Cases (due to ARB) were matched to controls (without ARB) according to year, age, sex, infection, and bacterium. Healthcare-associated (HCAI) and community-acquired (CAI) infections were analysed separately; logistic regressions were stratified by sex. RESULTS From 9460 cases identified, 6468 CAIs and 2855 HCAIs were matched with controls. Over a 12-months window, the risk increased when exposure occurred within the last 3 months. The following risk factors were identified: antibiotic exposure, with an OR reaching 3.6 [2.8-4.5] for men with CAI, mostly associated with broad-spectrum antibiotics; surgical procedure on urinary tract (OR 2.0 [1.5-2.6] for women with HCAI and 1.3 [1.1-1.6] for men with CAI); stay in intensive care unit > 7 days (OR 1.7 [1.2-2.6] for men with HCAI). Studied co-morbidities had no impact on ARB. CONCLUSIONS This study points out the critical window of 3 months for antibiotic exposure, confirms the impact of broad-spectrum antibiotic consumption on ARB, and supports the importance of prevention during urological procedures, and long intensive care unit stays.

Abstract
OBJECTIVE Identify research gaps relevant to the global effort to combat antimicrobial resistance. METHODS Web of Science, PubMed, Scopus, and Ovid MEDLINE were searched for reviews on antimicrobial resistance published between January 1, 2015 and December 31, 2019. Recommendations for future research were identified. FINDINGS Seventy-four reviews met inclusion criteria; 300 research gaps and recommendations were identified. The largest number were from the human health sector (105; 35%) followed by environmental health (72; 23%), animal health (66; 22%), food and feed (14; 5%), and plants and crops (8; 3%); 35 (12%) involved more than one sector. The largest number of gaps concerned surveillance of resistance (68; 23%), followed by study design or methodology (52; 17%), interventions (41; 14%), risk assessment and modeling (35; 12%), ecological (26; 9%) and biochemical (28; 9%) aspects of resistance, interface between reservoirs of resistant pathogens (24; 8%), and economic (15; 5%) and awareness- and behavior-related (11; 4%) aspects of antimicrobial resistance. CONCLUSIONS Important research gaps remain in our complete understanding of antimicrobial resistance, and more research is needed about its development, transmission, and impact across the interface of human, animal, and environmental reservoirs.

Abstract
BACKGROUND Looking only at the index infection, studies have described risk factors for infections caused by resistant bacteria. We hypothesized that septic patients with bloodstream infections may transition across states characterized by different microbiology and that their trajectory is not uniform. We also hypothesized that baseline risk factors may influence subsequent blood culture results. METHODS All adult septic patients with positive blood cultures over a 7-year period were included in the study. Baseline risk factors were recorded. We followed all survivors longitudinally and recorded subsequent blood culture results. We separated states into bacteremia caused by gram-positive cocci, susceptible gram-negative bacilli (sGNB), resistant GNB (rGNB), and Candida spp. Detrimental transitions were considered when transitioning to a culture with a higher mortality risk (rGNB and Candida spp.). A multistate Markov-like model was used to determine risk factors associated with detrimental transitions. RESULTS A total of 990 patients survived and experienced at least 1 transition, with a total of 4282 transitions. Inappropriate antibiotics, previous antibiotic exposure, and index bloodstream infection caused by either rGNB or Candida spp. were associated with detrimental transitions. Double antibiotic therapy (beta-lactam plus either an aminoglycoside or a fluoroquinolone) protected against detrimental transitions. CONCLUSION Baseline characteristics that include prescribed antibiotics can identify patients at risk for subsequent bloodstream infections caused by resistant bacteria. By altering the initial treatment, we could potentially influence future bacteremic states.

Abstract
BACKGROUND Antibiotic over prescription for upper respiratory tract infections (URTIs) in primary care exacerbates antimicrobial resistance. There is a need for effective alternatives to antibiotic prescribing. Honey is a lay remedy for URTIs, and has an emerging evidence base for its use. Honey has antimicrobial properties, and guidelines recommended honey for acute cough in children. OBJECTIVES To evaluate the effectiveness of honey for symptomatic relief in URTIs. METHODS A systematic review and meta-analysis. We searched Pubmed, Embase, Web of Science, AMED, Cab abstracts, Cochrane Library, LILACS, and CINAHL with a combination of keywords and MeSH terms. RESULTS We identified 1345 unique records, and 14 studies were included. Overall risk of bias was moderate. Compared with usual care, honey improved combined symptom score (three studies, mean difference -3.96, 95% CI -5.42 to -2.51, I2=0%), cough frequency (eight studies, standardised mean difference (SMD) -0.36, 95% CI -0.50 to -0.21, I2=0%) and cough severity (five studies, SMD -0.44, 95% CI -0.64 to -0.25, I2=20%). We combined two studies comparing honey with placebo for relieving combined symptoms (SMD -0.63, 95% CI -1.44 to 0.18, I2=91%). CONCLUSIONS Honey was superior to usual care for the improvement of symptoms of upper respiratory tract infections. It provides a widely available and cheap alternative to antibiotics. Honey could help efforts to slow the spread of antimicrobial resistance, but further high quality, placebo controlled trials are needed.

Pelargonium sidoides root extract for the treatment of acute cough due to lower respiratory tract infection in adults: a feasibility double-blind, placebo-controlled randomised trial. BMC Complement Med Ther 2021; 21:48.

Abstract
BACKGROUND Pelargonium sidoides DC (Geraniaceae) root extract, EPs®7630 or "Kaloba®", is a widely used herbal remedy for respiratory infections, with some evidence of effectiveness for acute bronchitis. However, it is not yet widely recommended by medical professionals in the UK. There is a need to undertake appropriately designed randomised trials to test its use as an alternative to antibiotics. The aim was to assess the feasibility of conducting a double-blind randomised controlled trial of Pelargonium sidoides root extract for treatment of acute bronchitis in UK primary care, investigating intervention compliance, patient preference for dosage form and acceptability of patient diaries. STUDY DESIGN Feasibility double-blind randomised placebo-controlled clinical trial. METHODS We aimed to recruit 160 patients with cough (≤ 21 days) caused by acute bronchitis from UK general practices. Practices were cluster-randomised to liquid or tablet preparations and patients were individually randomised to Kaloba® or placebo. We followed participants up for 28 days through self-reported patient diaries with telephone support and reviewed medical records at one month. Outcomes included recruitment, withdrawal, safety, reconsultation and symptom diary completion rates. We also assessed treatment adherence, antibiotic prescribing and consumption, mean symptom severity (at days 2-4 after randomisation) and time to symptom resolution. We interviewed 29 patients and 11 health professionals to identify barriers and facilitators to running such a randomised trial. RESULTS Of 543 patients screened, 261 were eligible, of whom 134 (51%) were recruited and 103 (77%) returned a completed diary. Overall, 41% (41/100) of patients took antibiotics (Kaloba® liquid group: 48% [15/31]; placebo liquid group: 23% [6/26]; Kaloba® tablet group: 48% [9/21]; placebo tablet group: 50% [11/22]). Most patients adhered to the study medication (median 19 out of 21 doses taken in week 1, IQR 18-21 - all arms combined). There were no serious adverse events relating to treatment. Most patients interviewed found study recruitment to be straightforward, but some found the diary too complex. CONCLUSIONS It was feasible and acceptable to recruit patients from UK primary care to a double-blind placebo-controlled trial of herbal medicine (Kaloba®) for the treatment of acute bronchitis, with good retention and low data attrition. TRIAL REGISTRATION HATRIC was registered on the ISRCTN registry ( ISRCTN17672884 ) on 16 August 2018, retrospectively registered. The record can be found at http://www.isrctn.com/ISRCTN17672884 .

Abstract
Background Communities need to see antibiotic stewardship campaigns as relevant to enhance understanding of antibiotic use and influence health-seeking behaviour. Yet, campaigns have often not sought input from the public in their development. Objectives To co-produce evidenced-based infographics (EBIs) about antibiotics for common childhood infections and to evaluate their effectiveness at increasing parents’ understanding of antibiotic use. Methods A mixed-methods study with three phases. Phase 1 identified and summarized evidence of antibiotic use for three childhood infections (sore throat, acute cough and otitis media). In phase 2, we co-designed a series of prototype EBIs with parents and a graphic design team (focus groups). Thematic analysis was used to analyse data. Phase 3 assessed the effect of EBIs on parents’ understanding of antibiotic use for the three infections using a national online survey in the UK. Results We iteratively co-produced 10 prototype EBIs. Parents found the evidence displayed in the EBIs novel and relevant to their families. Parents did not favour EBIs that were too medically focused. Parents preferred one health message per EBI. We included eight EBIs in a national survey of parents (n = 998). EBIs improved knowledge by more than a third across the board (34%, IQR 20%–46%, P < 0.001). Respondents confirmed that EBIs were novel and potentially useful, corroborating our focus groups findings. Conclusions Co-designed EBIs have the potential to succinctly change parents’ perceptions about antibiotics for acute respiratory tract infections in children. Further research should test EBIs in real-world settings to assess their reach as a potential public-facing intervention.

Abstract
(1) Background: The high use of antibiotics has made the issue of antimicrobial resistance (AMR) increasingly serious, which poses a substantial threat to the health of animals and humans. However, there remains a certain gap in the AMR system and risk assessment models between China and the advanced world level. Therefore, this paper aims to provide advanced means for the monitoring of antibiotic use and AMR data, and take piglets as an example to evaluate the risk and highlight the seriousness of AMR in China. (2) Methods: Based on the principal component analysis method, a drug resistance index model of anti-E. coli drugs was established to evaluate the antibiotic risk status in China. Additionally, based on the second-order Monte Carlo methods, a disease risk assessment model for piglets was established to predict the probability of E. coli disease within 30 days of taking florfenicol. Finally, a browser/server architecture-based visualization database system for animal-derived pathogens was developed. (3) Results: The risk of E. coli in the main area was assessed and Hohhot was the highest risk area in China. Compared with the true disease risk probability of 4.1%, the result of the disease risk assessment model is 7.174%, and the absolute error was 3.074%. Conclusions: Taking E. coli as an example, this paper provides an innovative method for rapid and accurate risk assessment of drug resistance. Additionally, the established system and assessment models have potential value for the monitoring and evaluating AMR, highlight the seriousness of antimicrobial resistance, advocate the prudent use of antibiotics, and ensure the safety of animal-derived foods and human health.

'I don't know if we can really, really change that': a qualitative exploration of public perception towards antibiotic resistance in France. JAC Antimicrob Resist 2020; 2:dlaa073.

Abstract
Background Since the 2000s, French authorities have put in place various national plans to make the general public aware of antibiotic stewardship. Twenty years later, France is still one of the countries with the highest use of antibiotics in Europe. Objectives Our study explored the general public’s perceptions of antibiotic resistance, their behaviour around antibiotic use and their expectations regarding awareness campaigns. Methods A qualitative study was performed from March 2018 to March 2019 in a French region using focus groups. Two types of public were targeted: parents of young children and retired people. The interview guide contained open-ended questions organized around three main themes: perceptions of antibiotic resistance; experience and use of antibiotics; and health information and campaigns. Results Nine focus groups were created, including 17 parents and 19 retirees. Participants did not link antibiotic overuse and antibiotic resistance. Antibiotic resistance was not perceived as a personal responsibility but as a suffered phenomenon on which the participants could not act. The blame was particularly put on the presence of antibiotics in the environment. Although participants expressed trust in their GPs, antibiotics remained perceived as the only solution for them to be cured quickly. Conclusions The study highlighted that the GPs were the preferred information source regarding the use of antibiotics. Actions targeting the public and health professionals will have little impact if, at the same time, efforts on work environment representation are not undertaken.

Abstract
BACKGROUND There remains public misconception about antibiotic use and resistance. Preschool children are at particular risk of receiving unnecessary antibiotics because they commonly present in primary care and many childhood infections are self-limiting. OBJECTIVES The aim of our study was to explore parents' perceptions and understanding of antibiotic use and resistance in the context of their young child with an acute respiratory tract infection (RTI) and to explore strategies parents would find acceptable to minimize antibiotic resistance for their families. METHODS Semi-structured interviews were conducted with 23 parents of preschool children who recently had an acute RTI across greater Oxfordshire, UK (2016-17 winter). We explored their beliefs about antibiotics, understanding of antibiotic resistance and views on current public antibiotic awareness campaigns at the time. Thematic analysis was used to analyse the data. RESULTS Parents had a sense of optimism and considered their families to be at low risk of antibiotic resistance because their families were 'low users' of antibiotics. Very few parents considered antibiotic resistance as a possible harm of antibiotics. Parents thought they were acting morally responsibly by following campaign messages. They wanted future campaigns to have a relevant, accessible message for families about the impact of antibiotic resistance. CONCLUSIONS Future communication about the potential impact of unnecessary antibiotic use and antibiotic resistance needs to focus on outcomes that parents of young children can relate to (e.g. infection recurrence) and in a format that parents will engage with (e.g. face-to-face dissemination at playgroups and parent/child community events) to make a more informed decision about the risks and benefits of antibiotics for their child.

Abstract
Background Promoting evidence-based antibiotic prescribing through successful antimicrobial stewardship (AMS) programmes is critical to preserving the effectiveness of antibiotics for common infections in primary care. This requires a coordinated multidisciplinary effort. Such pharmacist–prescriber partnerships have been effective in high-income countries (HICs). Yet, evidence generated in such countries is not always applicable because of different social determinants of health. Methods A multidisciplinary workshop was conducted with pharmacists and clinicians (doctors, nurses) on community-based antibiotic stewardship, the purpose of which was to explore how and where such partnerships might work in publicly funded primary care clinics in the greater Cape Metro region. Results Participants perceived that promoting effective AMS was a priority for South African primary healthcare. However, it was clear that there are many hurdles to overcome working in settings that are relatively resource-poor. Prescribing guidelines needed to be harmonised. Participants felt that staff training on the principles of AMS should be mandatory. Research was urgently needed to better understand their community’s understanding of antibiotic use and AMS, and to champion outreach projects in the community. Conclusion Important stakeholder perspectives in the community were highlighted to promote a multidisciplinary approach to AMS initiatives in primary care. These will need to be addressed to optimise antibiotic prescribing in the community.

Abstract
Importance Peripheral neuropathy has been associated with systemic fluoroquinolone exposure, but risk has been poorly quantified. Objective To calculate relative and absolute risk estimates for the association of fluoroquinolone exposure with peripheral neuropathy and to examine how risk may be affected by timing of fluoroquinolone exposure and by other risk factors. Design, Setting, and Participants This nested case-control study used anonymized data from all patients routinely registered with general practices in The Health Improvement Network database, a large primary care population database in the United Kingdom, from January 1, 1999, to December 31, 2015. Data analyses were conducted January 8, 2018. The cohort consisted of 1 338 900 adults issued 1 or more prescriptions of fluoroquinolone (34.3%) or amoxicillin-clavulanate (65.7%) antibiotics. Adults with incident peripheral neuropathy were matched (on age, sex, general practice, and calendar time) with up to 4 controls by using incidence density sampling selected from a cohort prescribed oral fluoroquinolone or amoxicillin-clavulanate antibiotics. Incidence rate ratios of peripheral neuropathy were calculated for fluoroquinolone and for amoxicillin-clavulanate exposure and compared with nonexposure among patients without diabetes, with sensitivity analyses testing the consistency of the results. Population mean-adjusted rate differences were then estimated, including the number needed to harm for various durations of fluoroquinolone therapy. Exposures Current and cumulative exposure to oral fluoroquinolone or amoxicillin-clavulanate antibiotics. Main Outcomes and Measures Incident peripheral neuropathy cases recorded in electronic medical records. Results In total, 5357 patients with incident peripheral neuropathy (mean [SD] age, 65.6 [14.7] years; 2809 women [52.4%]) were matched to 17 285 controls (mean [SD] age, 64.4 [15.2] years; 9485 women [54.9%]) without diabetes. Current oral fluoroquinolone exposure was associated with an increased relative incidence of peripheral neuropathy compared with nonexposure (adjusted incident rate ratio, 1.47; 95% CI, 1.13-1.92). Risk increased by approximately 3% for each additional day of current fluoroquinolone exposure and persisted for up to 180 days following exposure. No significant increased risk was observed with oral amoxicillin-clavulanate exposure. The absolute risk with current oral fluoroquinolone exposure was 2.4 (95% CI, 1.8-3.1) per 10 000 patients per year of current use. The number needed to harm for a 10-day course was 152 083 patients (95% CI, 117 742-202 778) and was greatest among men and among patients older than 60 years. Conclusions and Relevance The results of the present study suggested that oral fluoroquinolone therapy was associated with an increased risk of incident peripheral neuropathy that may depend on the timing of the exposure and the cumulative dose. Health care professionals should consider these potential risks when prescribing fluoroquinolone antibiotics.

Antibiotics (Basel) 2020; 9:antibiotics9060284. [PMID: 32466463 PMCID: PMC7344424 DOI: 10.3390/antibiotics9060284] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 05/22/2020] [Accepted: 05/24/2020] [Indexed: 12/20/2022] Open
Abstract
Background: Urinary tract infections (UTIs) are the most common bacterial infections among kidney transplant (KTX) recipients. The purpose of this study was to analyze antimicrobial resistance (AMR) in four most common pathogens responsible for UTIs in KTX recipients and determine risk factors (RF) for resistance in the same group. Methods: Analyzed antibiograms were based on urine samples positive for bacterial growth of 105 colony-forming units (CFU)/mL obtained from hospitalized adult KTX recipients presenting with UTI symptoms upon admission to the center in years 2011–2018. Results: In total, 783 antibiograms were analyzed for Klebsiella pneumoniae (258 samples, 33.0%), Escherichia coli (212, 27.0%), Enterococcus faecalis (128, 24.0%), and Enterococcus faecium (125, 16.0%). The decrease in susceptibility of E. coli to amoxicillin/clavulanic acid (62.9% vs. 40.0%) and ciprofloxacin (100% to 40.0%) was observed. Susceptibility to gentamicin increased from 33.3% to 92.9% in E. faecium. Susceptibility to tigecycline remained 100% through all years in case of E. faecalis and E. faecium. Male gender was a RF for resistance to amoxicillin/clavulanic acid (p = 0.008), ciprofloxacin (p = 0.0003), trimethoprim/sulfamethoxazole (p = 0.00009), ceftriaxone (p = 0.0001), and cefuroxime axetil (p = 0.00038) in K. pneumoniae and against gentamicin in E. faecalis (p = 0.015). Higher resistance to ampicillin in E. faecalis (p = 0.012) and to ciprofloxacin (p = 0.0003), trimethoprim/sulfamethoxazole (p = 0.007), piperacillin/tazobactam (p = 0.003), ceftriaxone (p = 0.001), and cefuroxime axetil (p = 0.013) in K. pneumoniae was observed in higher age groups of patients. Diabetes as a cause of kidney insufficiency (p = 0.026) and kidney-pancreas transplantation (p = 0.014) was RF for resistance to ceftriaxone in K. pneumoniae. Conclusions: AMR in uropathogens from KTX recipients fluctuated. There were identifiable RFs for resistance in the examined bacteria–antibiotic combinations. We recommend continuous mapping of site-specific microorganisms as etiology and susceptibility may vary between institutions and over time.

Abstract
A series of 2-thio- and 2-seleno-acetamides bearing the benzenesulfonamide moiety were evaluated as Carbonic Anhydrase (CA, EC 4.2.1.1) inhibitors against different pathogenic bacteria such as the Vibrio cholerae (VchCA-α and VchCA-β), Burkholderia pseudomallei (BpsCA-β and BpsCA-γ), Mycobacterium tuberculosis (Rv3723-β) and the Salmonella enterica serovar Typhimurium (StCA2-β). The molecules represent interesting leads worth developing as innovative antibacterial agents since they possess new mechanism of action and isoform selectivity preferentially against the bacterial expressed CAs. The identification of potent and selective inhibitors of bacterial CAs may lead to tools also useful for deciphering the physiological role(s) of such proteins.

Multidrug-Resistant Infections Among Hospitalized Adults With Community-Acquired Pneumonia In An Indonesian Tertiary Referral Hospital. Infect Drug Resist 2019; 12:3663-3675. [PMID: 31819549 PMCID: PMC6883944 DOI: 10.2147/idr.s217842] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2019] [Accepted: 08/12/2019] [Indexed: 01/12/2023] Open
Abstract
Objectives To evaluate the clinical and microbiological appearance among hospitalized pneumonia patients focusing on resistance and risk factors for mortality in a referral hospital. Patients and methods The study was an observational retrospective study on patients with CAP from 2014 to 2016 at Dr Soetomo referral hospital of Surabaya, Indonesia. All positive cultures with antimicrobial susceptibility results from blood and respiratory specimens were included. Patients infected with drug-susceptible pathogens and MDR organisms were also assessed in terms of clinical characteristics, day-3 clinical improvement, and 14-day mortality. Results Of 202 isolates, 181 possessed antimicrobial susceptibility data. S. pneumoniae was the most prevalent pathogen causing CAP (18.3%). Most patients were empirically treated with ceftriaxone (n=75; 41.4%). Among beta-lactam antibiotics, the susceptibility to the third-generation cephalosporins remained relatively high, between 67.4% and 82.3%, compared with the other beta-lactams such as amoxicillin/clavulanate and ampicillin/sulbactam (a sensitivity rate of 36.5% and 47.5, respectively). For carbapenem antibiotics, imipenem and meropenem susceptibility was 69.6% and 82.3% respectively. Approximately 22% of isolates were identified as MDR that showed significant differences in clinical outcomes of 14-day mortality rates (p<0.001). Notably, patients with day-3 improvement had a lower risk of mortality (OR= 0.06; 95% CI= 0.02–0.19). Conclusion One-fifth of causative agents among hospitalized CAP cases were identified as MDR organisms. The pathogens of MDR and non-MDR CAP remain susceptible to the third-generation cephalosporins. Together with additional consideration of culture findings and Pneumonia Severity Index (PSI) assessment, a 3-day clinical assessment is essential to predict the prognosis of 14-day mortality. ![]()

Long-term impact of oral surgery with or without amoxicillin on the oral microbiome-A prospective cohort study. Sci Rep 2019; 9:18761. [PMID: 31822712 PMCID: PMC6904678 DOI: 10.1038/s41598-019-55056-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2018] [Accepted: 11/05/2019] [Indexed: 12/19/2022] Open
Abstract
Routine postoperative antibiotic prophylaxis is not recommended for third molar extractions. However, amoxicillin still continues to be used customarily in several clinical practices worldwide to prevent infections. A prospective cohort study was conducted in cohorts who underwent third molar extractions with (group EA, n = 20) or without (group E, n = 20) amoxicillin (250 mg three times daily for 5 days). Further, a control group without amoxicillin and extractions (group C, n = 17) was included. Salivary samples were collected at baseline, 1-, 2-, 3-, 4-weeks and 3 months to assess the bacterial shift and antibiotic resistance gene changes employing 16S rRNA gene sequencing (Illumina-Miseq) and quantitative polymerase chain reaction. A further 6-month follow-up was performed for groups E and EA. Seven operational taxonomic units reported a significant change from baseline to 3 months for group EA (adjusted p < 0.05). No significant change in relative abundance of bacteria and β-lactamase resistance genes (TEM-1) was observed over 6 months for any group (adjusted p > 0.05). In conclusion, the salivary microbiome is resilient to an antibiotic challenge by a low-dose regimen of amoxicillin. Further studies evaluating the effect of routinely used higher dose regimens of amoxicillin on gram-negative bacteria and antibiotic resistance genes are warranted.

[PMID: 31772084 PMCID: PMC6887073 DOI: 10.1136/bmjopen-2019-029260] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Revised: 09/20/2019] [Accepted: 11/07/2019] [Indexed: 11/30/2022] Open
Abstract
Broad-spectrum antibiotics are routinely prescribed empirically in the resource-poor settings for suspected acute common infections, which drive antimicrobial resistance. Point-of-care testing (POCT) might increase the appropriateness of decisions about whether and which antibiotic to prescribe, but implementation will be most effective if clinician's perspectives are taken into account. OBJECTIVES To explore the perceptions of South African primary care clinicians working in publicly funded clinics about: making antibiotic prescribing decisions for two common infection syndromes (acute cough, urinary tract infection); their experiences of existing POCTs; their perceptions of the barriers and opportunities for introducing (hypothetical) new POCTs. DESIGN, METHOD, PARTICIPANTS, SETTING Qualitative semistructured interviews with 23 primary care clinicians (nurses and doctors) at publicly funded clinics in the Western Cape Metro district, South Africa. Data were analysed using thematic analysis. RESULTS Clinicians reported that their antibiotic prescribing decisions were influenced by their clinical assessment, patient comorbidities, social factors (eg, access to care) and perceived patient expectations. Their experiences with currently available POCTs were largely positive, and they were optimistic about the potential for new POCTs to: support evidence-based prescribing decisions that might reduce unnecessary antibiotic prescriptions; reduce the need for further investigations; support effective communication with patients, especially when antibiotics were unlikely to be of benefit. Resources and workflow disruption were seen as the main barriers to uptake into routine care. CONCLUSIONS Clinicians working in publicly funded clinics in the Western Cape Metro of South Africa saw POCTs as potentially useful for positively addressing both clinical and social drivers of the overprescribing of broad-spectrum antibiotics, but were concerned about the resource implications and disruption of existing patient workflows.

Antibiotic exposure and 'response failure' for subsequent respiratory tract infections: an observational cohort study of UK preschool children in primary care. Br J Gen Pract 2019; 69:e638-e646. [PMID: 31405831 PMCID: PMC6692084 DOI: 10.3399/bjgp19x705089] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Accepted: 02/21/2019] [Indexed: 01/21/2023] Open
Abstract
Background Childhood antibiotic exposure has important clinically relevant implications. These include disruption to the microbiome, antibiotic resistance, and clinical workload manifesting as treatment ‘failure’. Aim To examine the relationship between the number of antibiotic courses prescribed to preschool children for acute respiratory tract infections (RTI), in the preceding year, and subsequent RTIs that failed to respond to antibiotic treatment (‘response failures’). Design and setting A cohort study using UK primary care data from the Clinical Practice Research Datalink, 2009 to 2016. Method Children aged 12 to 60 months (1 to 5 years) who were prescribed an antibiotic for an acute RTI (upper and lower RTI or otitis media) were included. One random index antibiotic course for RTI per child was selected. Exposure was the number of antibiotic prescriptions for acute RTI up to 12 months before the index antibiotic prescription. The outcome was ‘response failure’ up to 14 days after index antibiotic prescription, defined as: subsequent antibiotic prescription; referral; hospital admission; death; or emergency department attendance within 3 days. The authors used logistic regression models to estimate the odds between antibiotic exposure and response failure. Results Out of 114 329 children who were prescribed an antibiotic course for acute RTI, children who received ≥2 antibiotic courses for acute RTIs in the preceding year had greater odds of response failure; one antibiotic course: adjusted odds ratio (OR) 1.03 (95% confidence interval [CI] = 0.88 to 1.21), P = 0.67, n = 230 children; ≥2 antibiotic courses: adjusted OR 1.32 (CI = 1.04 to 1.66), P = 0.02, n = 97. Conclusion Childhood antibiotic exposure for acute RTI may be a good predictor for subsequent response failure (but not necessarily because of antibiotic treatment failure). Further research is needed to improve understanding of the mechanisms underlying response failure.

Abstract
Background All-cause antibiotic prescribing affects bowel flora antimicrobial susceptibility, and may increase risk of urinary autoinoculation with antibiotic-resistant microbes. However, little is known about relative prevalence of, or risk factors for, antimicrobial resistance among potentially pathogenic microbes thought to be contaminating and infecting urine. Methods Secondary analysis of 824 children under 5 years of age consulting in primary care for an acute illness and their Escherichia coli isolates cultured at ≥103 cfu/mL from the Diagnosis of Urinary Tract infection in Young children (DUTY) study. Multivariable logistic regression investigating risk factors for resistance to amoxicillin, co-amoxiclav, cefalexin, ciprofloxacin, trimethoprim, nitrofurantoin and cefpodoxime in microbes meeting the laboratory criteria for urinary tract infection: ‘pathogens’ (>105 cfu/mL, n = 79) and ‘contaminants’ (103 to 105 cfu/mL, n = 745). Results Forty-three percent of E. coli were resistant to at least one tested antibiotic, with resistance highest to amoxicillin (49.37% pathogenic versus 37.32% contaminant, P = 0.04), trimethoprim (27.85% versus 16.52%, P = 0.01) and co-amoxiclav (16.46% versus 21.48%, P = 0.30). Multidrug resistance (to ≥3 antibiotic groups) was present in 17.07% of pathogens and 30.13% of contaminants (P = 0.04). No isolates were resistant to nitrofurantoin. Recent (0–3 months) exposure to antibiotics was associated with resistance in both pathogens (aOR: 1.10, 95% CI: 1.01–4.39) and contaminants (1.69, 1.09–2.67). Conclusions Prevalence of resistance (including multidrug) was high, but there was no consistent relationship between isolate pathogen/contamination status and resistance. Recent all-cause antibiotic prescribing increased the probability of antimicrobial resistance in both pathogenic and contaminating urinary E. coli in children in primary care.

Abstract
INTRODUCTION Care home residents are at increased risk of infections and antibiotic prescription. Reduced antibiotic use from fewer infections would improve quality of life. The Probiotics to Reduce Infections iN CarE home reSidentS (PRINCESS) trial aims to determine the efficacy and investigate mechanisms of daily probiotics on antibiotic use and incidence of infections in care home residents. METHODS AND ANALYSIS PRINCESS is a double-blind, individually randomised, placebo-controlled trial that will assess the effect of a daily oral probiotic combination of Lactobacillus rhamnosus, GG (LGG) and Bifidobacterium animalis subsp. lactis, BB-12 (BB-12) on cumulative antibiotic administration days (CAADs) (primary outcome) for infection in up to 330 care home residents aged ≥65 years over up to 12 months. Secondary outcomes include: Infection: Total number of days of antibiotic administration for each infection type (respiratory tract infection, urinary tract infection, gastrointestinal infection, unexplained fever and other); number, site, duration of infection; estimation of incidence and duration of diarrhoea and antibiotic-associated diarrhoea; Stool microbiology: Clostridium difficile infection; Gram-negative Enterobacteriaceae and vancomycin-resistant enterococci; LGG and BB-12. Oral microbiology: Candida spp. Health and well-being: Self and/or proxy health-related quality of life EQ5D (5 L); self-and/or proxy-reported ICEpop CAPability measure for older people. Hospitalisations: number and duration of all-cause hospital stays. Mortality: deaths. Mechanistic immunology outcomes: influenza vaccine efficacy (haemagglutination inhibition assay and antibody titres); full blood count and immune cell phenotypes, plasma cytokines and chemokines; cytokine and chemokine response in whole blood stimulated ex vivo by toll-like receptor 2 and 4 agonists; monocyte and neutrophil phagocytosis of Escherichia coli; serum vitamin D. ETHICS AND DISSEMINATION Ethics approval is from the Wales Research Ethics Committee 3. Findings will be disseminated through peer-reviewed journals and conferences; results will be of interest to patient and policy stakeholders. TRIAL REGISTRATION NUMBER ISRCTN16392920; Pre-results.

Abstract
Resistance to new antimicrobials can become widespread within 2-3 years. Resistance problems are particularly acute for bacteria that can experience selection as both harmless commensals and pathogenic hospital-acquired infections. New drugs, although welcome, cannot tackle the antimicrobial resistance crisis alone: new drugs must be partnered with more sustainable patterns of use. However, the broader experience of resistance management in other disciplines, and the assumptions on which resistance rests, is not widely appreciated in clinical and microbiological disciplines. Improved awareness of the field of resistance management could improve clinical outcomes and help shape novel solutions. Here, the aim is to develop a pragmatic approach to developing a sustainable integrated means of using antimicrobials, based on an interdisciplinary synthesis of best practice, recent theory and recent clinical data. This synthesis emphasizes the importance of pre-emptive action and the value of reducing the supply of genetic novelty to bacteria under selection. The weight of resistance management experience also cautions against strategies that over-rely on the fitness costs of resistance or low doses. The potential (and pitfalls) of shorter courses, antibiotic combinations and antibiotic mixing or cycling are discussed in depth. Importantly, some of variability in the success of clinical trials of mixing approaches can be explained by the number and diversity of drugs in a trial, as well as whether trials encompass single wards or the wider transmission network that is a hospital. Consideration of the importance of data, and of the initially low frequency of resistance, leads to a number of additional recommendations. Overall, reduction in selection pressure, interference with the transmission of problematic genotypes and multidrug approaches (combinations, mixing or cycling) are all likely to be required for sustainability and the protection of forthcoming drugs.

Abstract
OBJECTIVE The aim of this review was to collate all available evidence on the impact of point-of-care C reactive protein (CRP) testing on patient-relevant outcomes in children and adults in ambulatory care. DESIGN This was a systematic review to identify controlled studies assessing the impact of point-of-care CRP in patients presenting to ambulatory care services. Ovid Medline, Embase, Cochrane Database of Systematic Reviews, Cochrane CENTRAL, DARE, Science Citation Index were searched from inception to March 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Controlled studies assessing the impact of point-of-care CRP in patients presenting to ambulatory care services, measuring a change in clinical care, including but not limited to antibiotic prescribing rate, reconsultation, clinical recovery, patient satisfaction, referral and additional tests. No language restrictions were applied. DATA EXTRACTION Data were extracted on setting, date of study, a description of the intervention and control group, patient characteristics and results. Methodological quality of selected studies and assessment of potential bias was assessed independently by two authors using the Cochrane Risk of Bias tool. RESULTS 11 randomised controlled trials and 8 non-randomised controlled studies met the inclusion criteria, reporting on 16 064 patients. All included studies had a high risk of performance and selection bias. Compared with usual care, point-of-care CRP reduces immediate antibiotic prescribing (pooled risk ratio 0.81; 95% CI 0.71 to 0.92), however, at considerable heterogeneity (I2=72%). This effect increased when guidance on antibiotic prescribing relative to the CRP level was provided (risk ratios of 0.68; 95% CI 0.63 to 0.74 in adults and 0.56; 95% CI 0.33 to 0.95 in children). We found no significant effect of point-of-care CRP testing on patient satisfaction, clinical recovery, reconsultation, further testing and hospital admission. CONCLUSIONS Performing a point-of-care CRP test in ambulatory care accompanied by clinical guidance on interpretation reduces the immediate antibiotic prescribing in both adults and children. As yet, available evidence does not suggest an effect on other patient outcomes or healthcare processes. PROSPERO REGISTRATION NUMBER CRD42016035426; Results.

Abstract
Fifteen years after its licensure, this revision assesses the role of cefditoren facing the current pharmacoepidemiology of resistances in respiratory human-adapted pathogens (Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae and Moraxella catarrhalis). In the era of post- pneumococcal conjugate vaccines and in an environment of increasing diffusion of the ftsI gene among H. influenzae isolates, published studies on the cefditoren in vitro microbiological activity, pharmacokinetic/pharmcodynamic (PK/PD) activity and clinical efficacy are reviewed. Based on published data, an overall analysis is performed for PK/PD susceptibility interpretation. Further translation of PK/PD data into clinical/microbiological outcomes obtained in clinical trials carried out in the respiratory indications approved for cefditoren in adults (tonsillitis, sinusitis, acute exacerbation of chronic bronchitis and community-acquired pneumonia) is commented. Finally, the role of cefditoren within the current antibiotic armamentarium for the treatment of community respiratory tract infections in adults is discussed based on the revised information on its intrinsic activity, pharmacodynamic adequacy and clinical/bacteriological efficacy. Cefditoren remains an option to be taken into account when selecting an oral antibiotic for the empirical treatment of respiratory infections in the community caused by human-adapted pathogens, even when considering changes in the pharmacoepidemiology of resistances over the last two decades.

Abstract
Overdiagnosis and overprescribing is common in current clinical practice of infectious diseases in primary care. On the basis of studies published in the medical literature we identify my means of a non-systematic review a total of 25 myths associated with the diagnosis and treatment and present the literature pertaining to each myth. These myths result in extraneous testing (overdiagnosis) and excessive antimicrobial treatment (overtreatment). Most of these myths are ingrained among general practitioners in our country. Not only should these myths be debunked from our clinical practice, but they should also be reversed, and we encourage our readers to critically appraise their practice when it comes down to the misconceptions treated in this manuscript. We attempt to give guidance to clinicians facing these frequent clinical scenarios.

Community pharmacy interventions to improve antibiotic stewardship and implications for pharmacy education: A narrative overview. Res Social Adm Pharm 2018; 15:627-631. [PMID: 30279131 DOI: 10.1016/j.sapharm.2018.09.017] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 09/25/2018] [Accepted: 09/25/2018] [Indexed: 12/16/2022]
Abstract
BACKGROUND Antibiotic resistance is one of the world's most pressing public health problems, resulting in over 23,000 deaths per year. One of the main contributing factors to antimicrobial resistance is antibiotic misuse and overuse. Community pharmacists can play a role in reducing antibiotic resistance, since they are one of the most accessible healthcare professionals. OBJECTIVE The purpose of this paper is to describe community pharmacy interventions and strategies to reduce antibiotic misuse and overuse and to discuss the implications for pharmacy training. METHODS A narrative overview strategy was employed to identify papers on antibiotic stewardship and the role of the community pharmacist. Our review examined potential stewardship strategies and interventions within community pharmacy practice that provide opportunities for pharmacists to engage or lead in the reduction of antimicrobial resistance. RESULTS We describe five promising community pharmacist-led intervention strategies: Collaborative Practice Agreements (CPAs), point-of-care (POC) testing, patient consultations, academic detailing and serving as an advocate for patients and other healthcare providers CONCLUSIONS: This review highlights topics that may warrant increased attention in pharmacy school curricula. Pharmacy schools may want to consider modifying their curricula to address the shifts in practice of the community pharmacist - emphasizing the expanded role of the pharmacist in patient care and public health issues such as outpatient antibiotic stewardship.
