The efficacies of imipenem when directed against methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) strains of Staphylococcus aureus were compared with those of oxacillin and vancomycin in a subcutaneous rat model, using chronically infected tissue cages. At three weeks after inoculation, stable chronic infections were established with average bacterial counts exceeding 10(6) cfu/mL tissue cage fluid for both strains. Intraperitoneal administration (twice a day for 7 days) of imipenem (80 mg/kg) or oxacillin (200 mg/kg) produced peak levels of 23 or 45 mg/L and through levels of < 0.1 and 5.7 mg/L, respectively. The therapeutic regimens of either imipenem (P < 0.001) or oxacillin (P < 0.02) administered for 7 days led to significant reductions in bacterial counts in the tissue cage fluids of animals chronically infected with MSSA. In contrast, imipenem was not effective against chronic MRSA tissue cage infections, despite the relatively low MIC of the infecting strain and the use of high dose (120 mg/kg) therapy. In-vitro susceptibility testings of MRSA performed before and after imipenem therapy demonstrated the emergence of a highly resistant subpopulation. [ABSTRACT FROM AUTHOR]

Candida spp is responsible for 70-90% of invasive fungal infections. Invasive candidiasis is usually diagnosed by blood culture; other microbiological methods such as PCR, beta-D-glucans and mannans/anti-mannans are available in addition to clinical scores such as the Candida score. Management includes antifungal therapy, removal of catheters and source control, follow-up blood cultures and fundus examination, one possible complication being endophthalmitis. Candida albicans is the most common species in Switzerland and is generally susceptible to all antifungal agents. One concern is the spread of Candida auris, due to multi-resistant strains and the propensity to spread within and between hospitals, which is difficult to control., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Tularaemia is a highly infectious, zoonotic disease caused by Francisella tularensis , which has become increasingly prevalent over the past decade. Depending on the route of infection, different clinical manifestations can be observed. We report a case of typhoidal tularaemia presenting as a febrile illness with gastrointestinal symptoms in a patient in her mid-80s. During the acute illness phase and in the context of alcohol-related liver cirrhosis, the patient developed progressive ascites. During paracentesis, spontaneous bacterial peritonitis was consistently reported. Blood culture revealed Gram-negative bacilli identified as F. tularensis upon microscopic examination. Immediate clinical improvement was observed after adaptation to a pathogen-specific antibiotic regime. Typhoidal tularaemia presents general, non-specific symptoms without the local manifestations seen in other forms of the disease, thus representing a diagnostic challenge. In the case of protracted fever and if the epidemiological context as well as possible exposure are compatible, tularaemia should be considered in the differential diagnosis., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

I study the effect of parental leave duration on maternal health in the short- to medium-run leveraging variation in parental leave duration induced by an Austrian policy reform in the year 2000. Using rich administrative data and a regression discontinuity framework, I find that long parental leave of 2.5 years instead of 1.5 years deteriorates maternal health. Worse mental health mainly drives this effect. Alternative channels such as differential fertility, long-term employment effects, a change in disposable income or alternative mode of childcare are unlikely to be of main importance. There is substantial heterogeneity with longer leave spells being less harmful for mothers with unhealthy babies proxied by low birth weight., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

Aortitis may be an incidental finding at imaging. It refers to inflammation of the aortic wall and sometimes may be hard to differentiate with the periaortitis, inflammation of tissues around the vessel. Their clinical presentation is as varied as their etiologies. Appropriate early management is essential for improving patient prognosis, as the diagnostic approach remains challenging., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Hantaviruses are enveloped zoonotic RNA viruses hosted by rodents and responsible in the Americas for hantavirus pulmonary syndrome. In Europe, they cause hemorrhagic fever with renal syndrome and its milder form, nephropathia epidemica. The disease begins abruptly with high fever, chills, headache, back pain and abdominal pain associated with nausea and vomiting. Diagnosis is primarily made by serology. There is currently no specific medication or preventive available in Europe. Treatment is symptomatic., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

In 2021, the European and American Infectious Diseases Societies published new guidelines for the treatment of Clostridiodes difficile colitis. They have opted for a change in practice with fidaxomicin being recommended as the first line of treatment, and vancomycin as a second choice. Metronidazole remains recommended only in cases where other treatments are not available. These choices have not been endorsed by the Swiss Infectious Diseases Society, which still proposes metronidazole as first-line treatment. As a matter of fact, this inexpensive treatment still presents a satisfactory efficacy on the strains of Clostridoides difficile found in Switzerland in the context of patients without risk factors and with low probability of relapse., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Since the introduction of antibiotics, successive waves of Staphylococcus aureus clones occurred, each one having characteristic susceptibility pattern to antibiotics and virulence factors. We report here the results of a molecular epidemiological surveillance of methicillin-resistant S. aureus (MRSA) in French-speaking Switzerland between 2006 and 2020 showing the emergence and disappearance of clones known for their international dissemination, and the sporadic appearance of other international clones. Since 2012, a marked decrease in the incidence of cases attributable to the biology of the clones and to the control measures taken in the hospitals has been observed. These results highlight the importance of continuous surveillance in order to better assess the burden of this multi-resistant pathogen in our region., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

This paper studies the effect of birth allowances (so-called baby bonus) on fertility, newborn health, and birth-scheduling in Switzerland. Switzerland provides an optimal quasi-experiment: 11 out of 26 cantons introduced a baby bonus during the last 50 years at different points in time. To identify the effect of changes in the baby bonus, we employ an event study with control groups using several administrative data sets on births, stillbirths, and infant deaths in Switzerland from 1969 to 2017. While there is no evidence for birth-scheduling, we find, however, a sizable but only temporary increase in the fertility rate of 5.5% and a permanent but diminishing increase in the birth weight of 2.8%. The latter effect is particularly strong at the lower end of the birth weight distribution. Furthermore, we document substantial heterogeneity by citizenship of mothers., (© 2021 The Authors.

Parental leave policies across the globe have become much more generous than they used to be. This is also true for prenatal maternal leave. While this may be costly in the short run, little is known about the effect of maternal employment during pregnancy on newborn health. In this paper, I exploit three sharp policy changes on the duration of paid parental leave in Austria that strongly affected the share of mothers who work up to the 32nd week of pregnancy. I use administrative data from Austria on the working history of women linked to the full Austrian birth register and coupled with a regression discontinuity framework to identify the effect of prenatal employment on their offspring. Maternal employment during pregnancy with the second child reacts strongly to these policy changes. The share of employed mothers sharply declined in 1990 by 19.1 percentage points, increased in 1996 by 6.9 percentage points and declined again by 6.4 percentage points in 2000. None of these changes in prenatal employment translated into effects on newborn health measured via birth weight, gestational length, and Apgar scores. This result holds true for mothers of different socioeconomic backgrounds and across industries. The effect is precisely estimated, which suggests that prenatal employment prior to the 32nd week of pregnancy does not causally affect the fetus for measures visible at birth., (Copyright © 2020 Elsevier B.V.

Background: Since its first description in December 2019, coronavirus disease 19 (COVID-19) has spread worldwide. There is limited information about presenting characteristics and outcomes of Swiss patients requiring hospitalisation. Furthermore, outcomes 30 days after onset of symptoms and after hospital discharge have not been described., Aims: To describe the clinical characteristics, outcomes 30 days after onset of symptoms and in-hospital mortality of a cohort of patients hospitalised for COVID-19 in a Swiss area., Methods: In this retrospective cohort study, we included all inpatients hospitalised with microbiologically confirmed COVID-19 between 1 March and 12 April 2020 in the public hospital network of a Swiss area (Fribourg). Demographic data, comorbidities and outcomes were recorded. Rate of potential hospital-acquired infection, outcomes 30 days after onset of symptoms and in-hospital mortality are reported., Results: One hundred ninety-six patients were included in the study. In our population, 119 (61%) were male and the median age was 70 years. Forty-nine patients (25%) were admitted to the intensive care unit (ICU). The rate of potential hospital-acquired infection was 7%. Overall, 30 days after onset of symptoms 117 patients (60%) had returned home, 23 patients (12%) were in a rehabilitation facility, 18 patients (9%) in a medical ward, 6 patients (3%) in ICU and 32 (16%) patients had died. Among patients who returned home within 30 days, 73 patients (63%) reported persistent symptoms. The overall in-hospital mortality was 17%., Conclusion: We report the first cohort of Swiss patients hospitalised with COVID-19. Thirty days after onset of the symptoms, 60% had returned home. Among them, 63% still presented symptoms. Studies with longer follow-up are needed to document long-term outcomes in patients hospitalised with COVID-19.

Actinomycosis is a chronic bacterial infection, caused by the genus Actinomyces, commensal of the digestive and genital tract. The most common presentation of the disease affects the cervicofacial region, but other anatomical sites in the abdomen, thorax and central nervous system may be involved. Differential diagnosis includes neoplasia. Prolonged culture of deep samples in an anaerobic environment is the gold standard of the diagnosis. The treatment of choice is intravenous penicillin G followed by oral amoxicillin for a total duration of 6 to 12 months. However, depending on the location and response to antibiotics, shorter therapy may be considered., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.
