Efficacy of an antimicrobial stewardship intervention for early adaptation of antibiotic therapy in high-risk neutropenic patients.

BACKGROUND: The 4th European Conference on Infections in Leukemia recommends early adaptation of empirical antibiotic therapy (EAT) for febrile neutropenia in stable patients. OBJECTIVES: To assess the efficacy of an antimicrobial stewardship (AMS) intervention promoting early de-escalation and discontinuation of EAT in high-risk neutropenic patients. METHODS: This before-after study was conducted in the hematology department of the University Hospital of Nice, France. The AMS intervention included the development of clinical decision support algorithms, a twice-weekly face-to-face review of all antibiotic prescriptions and monthly feedback on the intervention. The primary endpoint was overall antibiotic consumption during hospital stay, expressed as days of therapy (DOT). RESULTS: A total of 113 admissions were included: 56 during the pre-intervention period and 57 during the intervention period. Induction chemotherapy and conditioning for allogeneic stem cell transplantation were the most frequent reasons for admission. In the intervention period, there was a significant decrease in overall antibiotic consumption (median DOT 20 vs. 28 days, p = 0.006), carbapenem consumption (median DOT 5.5 vs. 9 days, p = 0.017) and anti-resistant Gram-positive agents consumption (median DOT 8 vs. 11.5 days, p = 0.017). We found no statistical difference in the rates of intensive care unit admission (9% in each period) and 30-day mortality (5% vs. 0%, p = 0.243). Compliance with de-escalation and discontinuation strategies was significantly higher in the intervention period (77% vs. 8%, p < 0.001). CONCLUSION: A multifaceted AMS intervention led to high compliance with early de-escalation and discontinuation of EAT and lower overall antibiotic consumption, without negatively affecting clinical outcomes.

Yellow fever vaccine-associated neurologic and viscerotropic disease: a 10-year case series of the French National Reference Center for Arboviruses with clinical and immunological insights.

BACKGROUND: Immunization against the Yellow fever virus (YFV) with the 17D live-attenuated vaccine is the most effective way to prevent the disease. However, unexpected severe adverse events can occur. They consist in a neurological impairment - neurological disease (YEL-AND), a YF-like illness - viscerotropic disease (YEL-AVD) or anaphylaxis. In this article, we describe the epidemiology, clinical and biological features of YEL-AND and YEL-AVD cases reported to the French National Reference Center for Arboviruses (NRCA) in the past 10 years. METHODS: We conducted a national, retrospective study using the database of the NRCA from June 2012 to June 2022. All patients whose biological samples were sent to the NRCA for detection of YFV by serology and/or RT-qPCR for a suspected vaccine-associated adverse event were included. We collected data by reading medical records and conducted complementary neuro-immunological analysis, followed by a search for autoimmunity against type-1-interferon when samples were available at the NRCA. RESULTS: There were 10 cases of YEL-AND and 2 cases of YEL-AVD reported to the NRCA in the past 10 years, which represented an overall incidence of 0.6 for 100 000 doses. A total of 6/12 cases were previously healthy patients (50%, mean age 31 years), and 4/12 cases had cardiovascular co-morbidities (42%, mean age 56 years). The majority of YEL-AND had a favourable outcome at 6 months of follow up. One YEL-AVD patient passed. In secondary analyses, we evidenced a significant blood cerebrospinal fluid (CSF) barrier dysfunction, without intrathecal synthesis of immunoglobulin and without argument for a neuron damage. We further detected a significant rate of anti-type-1alpha interferon antibodies in 3/10 tested patients (2 YEL-AND and 1 YEL-AVD). CONCLUSION: YEL-AND and YEL-AVD are rare events that can underlie defect in the innate immunity of apparently healthy or mild co-morbid subjects. Outcome was generally favourable in the YEL-AND cases of our series, but still life-threatening or even fatal in the YEL-AVD cases.

Acute Pyelonephritis with Bacteremia in an 89-Year-Old Woman Caused by Two Slow-Growing Bacteria: Aerococcus urinae and Actinotignum schaalii.

Aerococcus urinae is an aerobic Gram-positive coccus that grows as tiny alpha-hemolytic colonies. Actinotignum schaalii is a slow-growing facultative anaerobic Gram-positive rod. These bacteria are part of the urogenital microbiota of healthy patients, but can also be involved in urinary tract infections (UTIs), particularly in elderly men and young children. Because A. urinae and A. schaalii are fastidious and are difficult to identify with phenotypic methods, they are underestimated causes of UTIs. Their growth is slow and requires a blood-enriched medium incubated under an anaerobic or 5% CO2 atmosphere for 48 h and from 24 to 48 h for A. schaalii and A. urinae, respectively. Furthermore, accurate identification is only possible using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) or molecular-based methods. In rare cases, these bacteria can be responsible for invasive infections. We describe, here, an unusual case of bacteremic UTI caused by both A. schaalii and A. urinae in an 89-year-old woman. She presented with dyspnea, and bacteriuria was noted. This challenging clinical and microbiological diagnosis was made in our laboratory by Gram staining urine with a leucocyte count >50/µL and/or a bacterial count >14/µL urinary culture on a blood agar plate. After 10 days of antimicrobial treatment consisting of 2 g amoxicillin PO t.i.d., the patient was discharged with a complete clinical and biological recovery. A. schaalii and A. urinae are probably still underestimated causes of UTIs. Microbiologists could consider the presence of these two bacteria using appropriate culture and identification methods in cases where a positive direct examination of urine reveals small Gram-positive rods or cocci, where undocumented UTIs are present in elderly patients, but also where a urinary dipstick is negative for nitrites and is associated with leukocyturia.

Contributions and challenges of community pharmacists during the COVID-19 pandemic: a qualitative study.

BACKGROUND: Healthcare services across the world have been deeply impacted by the COVID-19 pandemic. In primary care, community pharmacists have had an important role in the frontline healthcare response to the pandemic. OBJECTIVES: This study aimed to explore the experiences, contributions and perceived challenges of community pharmacists regarding the provision of healthcare services during the COVID-19 pandemic. METHODS: Semi-structured qualitative interviews were conducted with community pharmacists in France. Participants were recruited through a professional organization of pharmacists combined with a snowballing technique. Interviews were transcribed and then analyzed using thematic analysis. RESULTS: A total of 16 community pharmacists participated in the interviews. Study participants described providing a range of novel services in response to the pandemic on top of continuing their usual services. All participants described providing preventative services to reduce and mitigate the spread of SARS-CoV-2, such as education on hygiene and social distancing, delivery of face masks and hand sanitizer and adjusting pharmacy premises. Most respondents also described being involved in SARS-CoV-2 detection through screening and performing antigen testing in pharmacies. Participants reported being actively involved in COVID-19 vaccination by educating the general public about vaccines, facilitating their distribution to general practitioners as well as administering vaccines. Over half the respondents described rapidly changing guidelines and service users' anxiety as challenges to the provision of healthcare services during the pandemic. CONCLUSIONS: This study suggests that community pharmacists have significantly contributed to the response to the COVID-19 pandemic by ensuring continuity of pharmaceutical services and providing novel screening, testing and vaccination services. Their roles and responsibilities during the COVID-19 health crisis indicate that they can play an important role in the management of emerging infectious diseases.

Perceptions, current practices, and interventions of community pharmacists regarding antimicrobial stewardship: A qualitative study.

BACKGROUND: Community health care accounts for the vast majority of antibiotic use in Europe. Given the threat of antimicrobial resistance (AMR), there is an urgent need to develop new antimicrobial stewardship (AMS) interventions in primary care that could involve different health care providers, including community pharmacists. OBJECTIVES: This study aimed to explore the perceptions, currents practices, and interventions of community pharmacists regarding AMS. METHODS: Semistructured qualitative interviews were conducted with community pharmacists in France. Participants were recruited through a professional organization of community pharmacists combined with a snowballing technique. Interviews were audio recorded, transcribed, and analyzed using thematic analysis. The Consolidated Framework for Implementation Research was used while developing the interview guide and carrying out thematic analysis. RESULTS: Sixteen community pharmacists participated. All the respondents had good awareness about antimicrobial resistance and believed that community pharmacists had an important role in tackling AMR. Some barriers to community pharmacists' participation in AMS were identified such as difficult interactions with prescribers, lack of time, and lack of access to patient medical records and diagnosis. Increased patient education, audits and feedback of antibiotic prescribing, increased point-of-care testing, and delayed prescribing were interventions suggested by the pharmacists to improve antibiotic use in primary care. Strategies cited by participants to facilitate the implementation of such interventions are increased pharmacist-general practitioner collaboration, specialized training, clinical decision support tools, and financial incentives. CONCLUSION: This study suggests that community pharmacists could play a greater role in infection management and AMS interventions. Further interprofessional collaboration is needed to optimize antibiotic prescribing and utilization in community health care.

Clinical Decision Support Systems for Antibiotic Prescribing: An Inventory of Current French Language Tools.

Clinical decision support systems (CDSSs) are increasingly being used by clinicians to support antibiotic decision making in infection management. However, coexisting CDSSs often target different types of physicians, infectious situations, and patient profiles. The objective of this study was to perform an up-to-date inventory of French language CDSSs currently used in community and hospital settings for antimicrobial prescribing and to describe their main characteristics. A literature search, a search among smartphone application stores, and an open discussion with antimicrobial stewardship (AMS) experts were conducted in order to identify available French language CDSSs. Any clinical decision support tool that provides a personalized recommendation based on a clinical situation and/or a patient was included. Eleven CDSSs were identified through the search strategy. Of the 11 CDSSs, only 2 had been the subject of published studies, while 9 CDSSs were identified through smartphone application stores and expert knowledge. The majority of CDSSs were available free of charge (n = 8/11, 73%). Most CDSSs were accessible via smartphone applications (n = 9/11, 82%) and online websites (n = 8/11, 73%). Recommendations for antibiotic prescribing in urinary tract infections, upper and lower respiratory tract infections, and digestive tract infections were provided by over 90% of the CDSSs. More than 90% of the CDSSs displayed recommendations for antibiotic selection, prioritization, dosage, duration, route of administration, and alternative antibiotics in case of allergy. Information about antibiotic side effects, prescription recommendations for specific patient profiles and adaptation to local epidemiology were often missing or incomplete. There is a significant but heterogeneous offer for antibiotic prescribing decision support in French language. Standardized evaluation of these systems is needed to assess their impact on antimicrobial prescribing and antimicrobial resistance.

A case of infective endocarditis caused by Arthrobacter woluwensis.

Corynebacteria are rare causative agents of infective endocarditis. This is a reported case of a destructive aorto-mitral infective endocarditis caused by Arthrobacter woluwensis. Microbial identification was achieved by 16S rRNA polymerase chain reaction on valve tissue samples. Outcome was favorable after surgical valve replacement and 4-week antibiotic treatment.

Gender differences in the earnings produced by a middle range education: The case of Canadian 'colleges'.

In this paper we use data on consecutive cohorts of recent graduates from community colleges or community college-like institutions to address the following questions about the gender earnings gap: i) What was the trend in the gender earnings gap for these recent graduates? ii) What role in the observed trends in the gender earnings gap was played by occupational demand? iii) How and to what extent did the domestic division of labour contribute to the gender earnings gap in this young sample? We find that the gap fell then rose, that occupational demand played a role in these shifts, and that the domestic division of labour did indeed contribute to the gap in this young sample. Furthermore, our results point to a process of cumulation of factors that increase the earnings gap which has both substantive and methodological implications.

Confusion between euthanasia and other end-of-life decisions: influences on public opinion poll results.

BACKGROUND: Public opinion polls indicate that a majority of Canadians are in favour of euthanasia. However, there have been many criticisms of the validity of these findings. The objective of this study was to assess public opinion towards euthanasia while controlling for possible threats to validity indicated in the literature review. METHODS: A telephone public opinion poll was conducted in 2002 with a representative sample of the general population of Quebec (n = 991; response rate = 49.8%). Respondents were asked about their support for euthanasia and treatment withdrawal and, for comparison, were asked a previously used question on euthanasia (Gallup) which has been criticized for methodological problems. Respondents were also asked to distinguish between euthanasia and other end-of-life decisions in hypothetical scenarios. RESULTS: Eleven percent more people supported euthanasia with the Gallup question than the question developed in this study. Support for euthanasia (69.6%) was less prevalent than for treatment withdrawal (85.8%). Respondents who failed to distinguish between euthanasia and treatment withdrawal or withholding treatment in hypothetical scenarios were more likely to support euthanasia in public opinion poll questions. Furthermore, there is a significant relationship between opinions about the acceptability of euthanasia and inaccurate knowledge of the nature of euthanasia. INTERPRETATION: Public opinion polls on euthanasia must be interpreted in the light of the wording of the question. Education of the population concerning euthanasia and other end-of-life decisions may be considered to be an important prerequisite to engage in public debate concerning the legalization of euthanasia.
