Background: Distinguishing self-limiting ('trivial') from potentially consequential spinal pain in childhood and adolescence is crucial to prevent over- or under-medicalization. The aim of this study was to stratify participants for severity of spinal pain and to investigate associations of pain severity with potential consequences of pain and some psychophysical and clinical factors., Methods: In 2020 and 2021, children and adolescents took part in a voluntary population-based spine screening event across Switzerland organized by the Swiss Chiropractors Association. The screening consisted of a questionnaire (14 questions) based on the Young Spine Questionnaire and a clinical examination by a chiropractor. Three subgroups of pain severity [no pain (including mild, occasional pain), one-sited moderate pain, one-sited severe or moderate/severe pain at multiple sites of the spine] were formed by combining the self-reported measures for pain intensity and pain frequency for two recall periods (lifetime, last week) according to literature. Multivariable logistic regression analyses were conducted to determine the associations between pain severity and potential pain consequences (impact of spinal pain on health and seeking medical advice because of spinal pain), as well as between pain severity and some psychophysical factors (head and/or belly pain, sleep problems, daytime tiredness) and clinical measures [trunk symmetry (rib hump), trunk muscle endurance (plank position)]., Results: Of all participants (N = 457; 6-16 years; mean age = 10.9 ± 3.0 years; 220 boys), those with most severe spinal pain and with one-sited moderate pain in the last week had higher odds for reporting an impact of spinal pain on their health (OR = 13.5, 95%CI = 4.9-36.8; OR = 4.7, 95%CI = 1.5-14.4) and for searching medical advice because of spinal pain (OR = 11.6, 95%CI = 4.5-30.1; OR = 3.9, 95%CI = 1.6-9.2). Headache and/or belly pain (OR = 2.6, 95%CI = 1.2-5.5) and daytime tiredness (OR = 3.2, 95%CI = 1.3-7.9) increased the odds for having most severe pain compared to having no pain. The clinical measures were not associated with pain severity., Conclusion: Stratification by pain severity, particularly when asked for pain in the last week, might help to minimize over- and under-medicalization of spinal pain in childhood and adolescence. Prospective studies are needed to clarify the relevance of the investigated clinical tests in the context of adolescent spinal pain., Competing Interests: Declarations.

Sickle cell anemia is the world's most common monogenic disease, with a steady rise in the number of cases also in Switzerland. It presents as regenerative anemia and recurrent vaso-occlusive episodes, which can impact all organs. Acute and chronic complications increase morbidity and mortality, significantly reducing life expectancy compared to the general population. Optimal and multidisciplinary management of acute events is essential to improve patients' quality of life and overall prognosis. Vaso-occlusive crises and acute chest syndrome are the two most frequent acute complications. Their treatment, described here, is threefold: analgesia, treatment of causative factors and prevention of further complications., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêt en relation avec cet article.

Background: The early assessment of the severity of polytrauma patients is key for their optimal management. The aim of this study was to investigate the discriminative performance of the NACA score in a large dataset by stratifying the severity of polytraumatized patients in correlation to injury severity score (ISS), Glasgow Coma Scale (GCS), and mortality., Methods: This study on the Swiss Trauma Registry investigated 2239 polytraumatized patient (54.3 ± 22.8 years) enrolled from 2015 to 2023: 0.5% were NACA 3, 76.7% NACA 4, 21.4% NACA 5, and 1.4% NACA 6. The NACA predictive value of patients' mortality was investigated, as well as the correlation of ISS and GCS scores, and other factors influencing patients' survival at discharge and after 28 days., Results: In NACA 4 and 5 the survival rate during hospitalization was 97.7% and 82.5%, respectively, and 28-day mortality 3.5% and 23.5%, respectively (p < 0.0005). NACA correlated with GCS in the prehospital phase and in the emergency room (p < 0.0005), as well as with ISS (p < 0.0005). NACA 4 and 5 presented different injury patterns (fall < 3 m vs vehicle accident) with NACA 5 requiring more CPR and intubation (p < 0.001, p < 0.0005). The ROC AUC analysis showed the prehospital NACA and GCS values as the strongest variables predicting patients' survival., Conclusions: This study provides valuable evidence supporting the effectiveness of the NACA score in assessing the severity of polytrauma patients in both the pre-ER and ER condition. Considering the statistical significant correlation with the GCS and with the ISS, NACA is a valid score for assessing polytrauma patients., Competing Interests: Declarations Ethics approval and consent to participate The study protocol was approved by the local cantonal ethics committee of the Canton of Tessin, Switzerland (prot 2024-00236 CE 4536).

Background: Hip fractures in older adults are common and carry a high risk of morbidity and mortality. Preoperative dehydration, a key risk factor for adverse outcomes, is often underdiagnosed at admission. It is important to identify high risk patients and optimize modifiable risk factors to improve the postoperative outcome. The p-POSSUM Score is a useful predictor of postoperative mortality risk. Implementing a defined fluid resuscitation protocol early in high-risk groups has proven effective in reducing both postoperative morbidity and mortality., Materials and Methods: We conducted a single-center, retrospective quality improvement study at a Level 1 trauma center in Switzerland, focusing on geriatric patients over 70 with a p-POSSUM Score > 5% and a proximal femur fracture, undergoing surgery between February 2015 and September 2019. We hypothesized that our institutional goal-directed fluid resuscitation protocol (GDT) would result in lower 30- and 90-day mortality rates and fewer complications for these high-risk patients. Outcome changes over time were analyzed annually., Results: 312 patients were included in our study. 147 followed our institutional GDT protocol, while 165 patients received standard care and were used as a control group. Initially, the odds ratio (OR) for 30-days mortality favored the GDT group; 2015 0.30 (CI: 0.07-1.18), 2016 0.28 (CI: 0.07-1.07), 2017 0.51 (CI: 0.13-2.04). This shifted toward the Non-GDT group in the year 2018 with a OR of 2.14 (CI: 0.59-7.84) and 2019 with 1.92 (CI 0.47-7.83). The pattern for 90-day mortality results was similar and slightly more pronounced. The estimates for the odds ratios remained consistent even after adjustment for the p-POSSUM score. The relative frequencies of complications showed no remarkable differences between the groups (GDT vs. Non-GDT)., Conclusion: In our study, the treatment according to our GDT protocol was associated with survival advantage in the first three years. However, this trend reversed in 2018, with Non-GDT patients faring better. Although our retrospective study does not provide enough evidence of causality between the protocol and the mortality rates, it revealed that continuous critical evaluation of internal processes is essential in healthcare for quality management. This allows timely identification and adaptation of processes to issues, especially after initially positive results., Competing Interests: Declarations Ethics approval and consent to participate All documents were handed over to the responsible ethics committee. As this was a retrospective quality assurance study of standard procedures, with no experimental interventions, no specific consent was required from the patients. For the interventions during treatment, the patients were informed verbally and in writing, and written consent was obtained.

Background: Knowledge about impact of age and comorbidities on outcome in patients with leadless pacemakers (LPM) is limited., Objectives: To analyse outcome in LPM patients according to age and comorbidities., Methods: This Swiss, multi-centre, retrospective analysis includes all patients with LPM implanted between 2015 and 2022. Charlson-Comorbidity-Index (CCI) was determined and patients were divided into a low- (CCI ≤ 5) and high-comorbidity (CCI > 5) group. Peri-procedural complications, in-hospital death, and all-cause mortalities were assessed. Finally, all-cause mortality according to three groups (CCI ≤ 3, 4-5, >5) was compared to age and sex-adjusted mortality in the general Swiss population., Results: 863 patients (median age 81 years, 65% male, 42% with CCI > 5) were included. Peri-procedural/long-term complication rates did not differ between the low- vs. high-comorbidity groups (2.6% vs. 1.7%, p = 0.48 and 1.2% vs. 2.8%, p = 0.12, respectively). In-hospital (3.6% vs. 0.6%, p = 0.002) and all-cause mortality (HR 2.9, 95%CI 2.2-3.8, p < 0.001) were significantly higher in the high-comorbidity group resulting in a three-year mortality of 58% (95%CI 51-65%) vs. 22% (95%CI 17-27%) in the low-comorbidity group. In patients with a CCI ≤ 3, all-cause mortality was comparable to the age- and sex-adjusted mortality of the general Swiss population., Conclusions: In elderly patients with high comorbidity, LPM implantation was not associated with increased peri-procedural/long-term complications. All-cause mortality in LPM patients with a CCI ≤ 3 was comparable to age- and sex-adjusted mortality in the general Swiss population. Despite a relatively high three-year mortality due to competing risk factors, LPM implantation is safe, even in elderly patients with high comorbidity., Condensed Abstract: In this Swiss, multi-centre, retrospective cohort analysis, 863 patients implanted with a leadless pacemaker were included and divided into a high-comorbidity (with a CCI > 5) and low-comorbidity (with a CCI ≤ 5) group. There was no between group difference in terms of implantation outcomes and peri-operative or long-term complications. Furthermore, all-cause mortality during follow-up in patients with a CCI ≤ 3 was comparable to age- and sex-adjusted mortality in the general Swiss population. These data indicate that LPM implantation is a safe procedure, even in elderly patients with high comorbidity., (Copyright © 2024 The Authors. Published by Elsevier B.V. All rights reserved.)

Introduction: Adolescent mental health is a global public health challenge as most cases remain undetected and untreated, and consequently, have a high likelihood of persistence or recurrence. It is critical to improve early detection of mental disorders and to target individuals experiencing subclinical symptoms. However, most indicated prevention approaches have been developed for risk syndromes of specific mental disorders. This contradicts the increasing recognition of emerging psychopathology as a complex system characterised by rapid shifts in subclinical symptoms, cutting across diagnostic categories and interacting with each other over time. Therefore, this study aims to examine the dynamic course, pattern and network of subclinical symptoms and transdiagnostic mechanisms over time., Method and Analysis: The EMERGE-study is a prospective, naturalistic, 1-year follow-up study. A general population sample of 1196 adolescents will be recruited. Inclusion criteria are age between 11 and 17 years, German language skills, main residency in Switzerland and access to internet. Individuals will be excluded if they have a current or lifetime axis I mental disorder. Assessments of subclinical symptoms of several mental disorders and potential transdiagnostic mechanisms will be conducted at baseline and at 3-month, 6-month, 9-month and 12-month follow-up. Structural equation modelling will be used to estimate the homotypic and heterotypic patterns of subclinical symptoms and the associations with transdiagnostic mechanisms. Latent growth mixture modelling and growth mixture survival analysis will be carried out to identify subclasses of individuals with different trajectories of subclinical symptoms that may be predictive of an onset of a mental disorder. Network analysis will be applied to assess the centrality of subclinical symptoms and how networks of emerging psychopathology change over time., Ethics and Dissemination: Ethical approval was obtained from the Bern Cantonal Ethics Committee (ID 2020-02108). All findings will be disseminated by publication in peer-reviewed scientific journals and by presentation of the results to conferences and stakeholder organisation events., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Mycoplasma pneumoniae pneumonia occurs periodically in an endemic-epidemic pattern. The incidence of this disease has fallen drastically as a result of the health measures imposed for the COVID-19 pandemic. In Switzerland, as elsewhere in the world, a new epidemic has been affecting pediatrics and adult populations since September 2023. Transmitted by aerosols and requiring close contact, this bacterium causes respiratory infections of varying severity, as well as a variety of extra-pulmonary manifestations. Microbiological diagnosis is based on PCR of respiratory samples. Despite a very high rate of macrolide resistance in Asia, the resistance rate remains low in Europe., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Background: Emerging research indicates the potential for early transition from intravenous to oral antimicrobial therapy in certain infections. This trend may have implications for outpatient parenteral antibiotic therapy (OPAT) programs, as the demand for prolonged intravenous treatment could decrease. The objective of this study was to evaluate the frequency and evolution of OPAT courses of ≥ 14 days over the years and determine the medical justification for those prolonged treatments., Methods: All patients treated intravenously for ≥ 14 days by the OPAT program at Lausanne University Hospital, Switzerland, between 2017 and 2022 were included in the study. Data were extracted from a prospectively established OPAT database. Prevalence of prolonged antibiotic treatment and its clinical and microbiological information were identified., Results: During the study period, a total of 2,448 treatment courses were administered: 1,636 intravenous (IV) and 812 oral treatments. Of the IV treatments courses, 749 (36%) were of a duration of ≥ 14 days, without discernible trend over the 6-year study period. The most common type of infections needing prolonged treatment were bone and joint infections (31%), endovascular infections (18%), complicated intra-abdominal infections (15%), and urinary tract infections (11%), with only minor fluctuations in these proportions during the study period. Finally, the use of second-line antibiotics (piperacillin-tazobactam, carbapenems and vancomycin) did not increase over the years, suggesting that prolonged intravenous antibiotic therapy is not linked to an increase of anti-microbial resistance in our cohort., Conclusions: Despite the general trend towards shorter intravenous treatment courses in infectious diseases, our OPAT unit did not observe a decline in the use of prolonged intravenous antibiotic therapy between 2017 and 2022, suggesting that OPAT units will probably not see a decrease in their activities in the near future., (© 2024.

The objective of this study was to determine the prevalence, molecular epidemiology, and risk factors for gut colonization with extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E), carbapenemase-producing Enterobacterales (CPE), and vancomycin-resistant enterococci (VRE) in healthcare workers (HCWs). In September/October 2022, we performed a cross-sectional study among HCW from 14 institutions in Northeastern Switzerland. HCWs reported risk factors for antimicrobial resistance (covering the last 12-24 months) and provided rectal swabs. Swabs were screened for ESBL-E, CPE, and VRE; whole-genome sequencing (WGS) was performed to assess the genetic relatedness. Logistic regression was used to identify occupational and non-occupational risk factors. Among approximately 22,500 employees, 1,209 participated (median age 46 years, 82% female). Prevalences of ESBL-E ( n = 65) and CPE ( n = 1) were 5.4% [95% confidence interval (CI) 4.2-6.8] and 0.1% (95% CI 0.0-0.5), respectively; no VREs were detected. In the multivariable analysis, non-European ethnicity [adjusted odds ratio (aOR) 7.0, 95% CI 1.4-27.3], travel to high-risk countries (aOR 4.9, 95% CI 2.5-9.3), systemic antibiotics (aOR 2.1, 95% CI 1.1-3.7), antibiotic eye drops (aOR 4.7, 95% CI 1.7-11.9), and monthly sushi consumption (aOR 2.4, 95% CI 1.4-4.3) were positively associated with ESBL-E colonization, whereas alcohol consumption (aOR 0.5 per glass/week, 95% CI 0.3-0.9) was negatively associated with ESBL-E colonization. Occupational factors showed no association. Among ESBL- Escherichia coli , ST131 (15 of 61, 25%) and bla CTX-M-15 (37/61; 61%) were most common; one isolate co-harbored bla OXA-244 . WGS data did not show relevant clustering. Occupational exposure is not associated with ESBL-E colonization in HCW. Given the potential public health and antibiotic stewardship implications, the role of sushi consumption and antibiotic eye drops as risk factors should be further elucidated., Competing Interests: The authors declare no conflict of interest.

Background: The social distancing measures associated with the COVID-19 pandemic had far reaching effects on sexual behavior worldwide. However, it remains unclear whether sexual contact with non-steady partners was a contributor to the spread of SARS-CoV-2. The aim of this study was to (i) describe risk factors for SARS-CoV-2 seropositivity after the first pandemic wave among people using HIV Pre-Exposure Prophylaxis (PrEP) in Zurich, Switzerland, including sexual contact with non-steady partners, and (ii) assess whether the SARS-CoV-2 seropositivity among PrEP users in this time period differed from that of a demographic matched population level comparison group., Methods: The study was conducted between July 2020 and October 2020 as a nested cross-sectional study within two ongoing cohort studies, SwissPrEPared (all eligible PrEP users in Switzerland ≥ 18 years old) and Corona Immunitas (a series of cross-sectional and longitudinal studies measuring the SARS-CoV-2 seroprevalence across Switzerland, beginning in April 2020). All SwissPrEPared participants were recruited from Checkpoint Zurich (the main PrEP clinic in Zurich) and were men having sex with men or transgender women. Data were collected on participants' SARS-CoV-2 antibody status, social characteristics and behavioral data after the first wave of the pandemic in Switzerland, and seroprevalence was compared with a propensity score-matched sample from the general Zurich population., Results: Of the 218 participants enrolled, 8.7% (n = 19, 95% CI: 5.5-13.5%) were seropositive for SARS-CoV-2 during the first pandemic wave, higher than that of the general male population in Zurich aged 20-65 (5.5%, 95% CI: 3.8-8.2%). Participants on average reduced their social outings, but the seronegative were more socially active before, during, and after the first lockdown period. In a logistic model, increasing mean sexual partner count was not associated with seropositivity (OR: 1.02, 95% CI: 0.95, 1.07). The estimated risk ratio for seropositivity for the participants compared to the general Zurich population after propensity score matching was 1.46 (95% CI: 0.53, 3.99)., Conclusions: Our study suggests that SARS-CoV-2 seropositivity was slightly elevated among people taking PrEP in Zurich during the first wave of the pandemic, but that socializing and sexual activity were less important than other factors in contributing to risk., (© 2024.

Background and Aims of the Study: Congenital syphilis is a rare complication of syphilis in pregnant women. Vertical transmission may occur at any time during pregnancy. The incidence of congenital syphilis has been increasing worldwide. Congenital syphilis has been a notifiable disease for many years in Switzerland but reporting does not include maternal features associated with syphilis in pregnancy or infant's subsequent development. We described syphilis cases among pregnant women screened over a 10-year period in Switzerland and subsequent cases of congenital syphilis, in order to identify maternal risk profiles and to optimise prevention. Second, we compared the characteristics of pregnant women screened early (1st trimester) vs late in pregnancy (2nd or 3rd trimester). Finally, we assessed the risk factors for premature birth among these women with syphilis., Methods: A multicentre retrospective study conducted in Swiss hospitals from 2012 to 2021, including pregnant women who screened positive for syphilis (Treponema pallidum haemagglutination assay [TPHA] / T. pallidum particle agglutination assay [TPPA ] ≥1:80) and newborns exposed to T. pallidum in utero and/or congenitally infected and with a positive syphilis serology at birth. Data were collected from medical records., Results: A total of 147 syphilis-positive pregnant women and 102 infants were included. A history of treated syphilis was known for 44% (65/147) of the mothers corresponding to a serological scar and the remaining 56% (82/147) were newly identified syphilis cases. Syphilis screening was done during the first trimester in 54%, second trimester in 29% and third trimester in 13% of cases. Two babies were diagnosed with congenital syphilis (1.96%). Several potential factors that could contribute to women's risk of syphilis during pregnancy were identified such as a foreign origin (93% of mothers), lack of healthcare insurance (25%), no employment status (37%), drug use (5%), co-infection with other sexually transmitted infections (24%) and a late first antenatal consultation (42%). The number of pregnant women without insurance was higher in women diagnosed in the second or third trimester than in those diagnosed in the first trimester (odds ratio 0.41; 95% CI 0.19-0.89; p = 0.024). Syphilis diagnosed in the second or third trimester was associated with a late first antenatal consultation (odds ratio 77.82; 95% CI 9.81-617.21; p <0.001). A high rate of intrauterine growth retardation and of preterm birth was observed in newborns (18% versus 6% in Switzerland in 2022)., Conclusion: Congenital syphilis remains rare in Switzerland. However, we found potential maternal factors associated with a positive syphilis serology during pregnancy, which can help to improve future prevention measures. The study protocol was registered on ClinicalTrials.gov (ID NCT05975502).

Introduction: The impairment of mental health among veterinary professionals has raised public awareness in recent years. The driving forces include a serious gap in veterinary services - with less available veterinary colleagues, especially in rural areas - and a general lack of veterinary graduates. This article presents the results of our first Swiss survey on psychological well-being in the veterinary profession. Our results are viewed both in the current context and in the context of developments that have already taken place in other medical disciplines. Results indicate higher levels of stress in veterinarians working as clinicians, in female colleagues, in veterinarians of younger age and veterinarians under employment. In the meantime, larger surveys such as the Vétos Entraide (https://vetos-entraide.com) were established in France and projects such as the Happy Vet project (https://happyvetproject.org) were launched in Switzerland for eg. the burnout prevention in the profession. However, the topic of «mental health» remains highly relevant in veterinary medicine and requires further research and measures, which should consider the identified predisposing factors, such as age and gender.

Objective: The aim of the study was to evaluate determinants of between-person variation in shoulder pain ("yes"/"no") in individuals with spinal cord injury living in Switzerland., Design: This longitudinal study used data from the Swiss Spinal Cord Injury Cohort community surveys 2012, 2017, and 2022. Logistic regression analyses were used to identify determinants of between-person variability in shoulder pain while controlling for within-person variability., Results: The prevalence of shoulder pain was 34.4% (95% CI = 33.0-35.9) when studying 4393 completed questionnaires. Significant determinants for between-subject variability revealed higher likelihoods for shoulder pain in females as compared with males (odds ratio: 1.57; 95% CI = 1.21-2.05), and when spasticity (1.49; 1.14-1.95), contractures (2.77; 2.21-3.48), and depression (1.39; 1.02-3.48) were present. In addition, shoulder pain presented highest likelihoods in individuals with incomplete tetraplegia (1.81; 1.32-2.48) versus incomplete paraplegia, in individuals over 26 yrs since injury (1.65; 1.15-2.37) versus up to 5 yrs since injury, and in individuals using a manual (2.17; 1.53-3.08) or electrical (2.16; 1.41-3.31) wheelchair versus no aids. There were significant interaction effects for gender with time since injury, contractures, and depression., Conclusions: Determinants of between-subject variability in shoulder pain were female gender, lesion severity, time since injury, specific health conditions, and wheelchair use., Competing Interests: Financial disclosure statements have been obtained, and no conflicts of interest have been reported by the authors or by any individuals in control of the content of this article., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: The objective of this study was to describe the use of digital health tools by people with spinal cord injury and associated factors., Design: Cross-sectional data from the 2022 Swiss Spinal Cord Injury Cohort Study (SwiSCI) were analyzed. Descriptive statistics summarized data regarding sociodemographic characteristics, self-management, health, and digital health usage. Multiple logistic regression analysis examined the association of digital health use with reasons of use, concerns, confidence, sociodemographic characteristics, self-management, and comorbidities., Results: Among 961 participants, 69% used digital health tools. Females were 1.79 times more likely to adopt them. People aged 60-70 had 3.84 times higher usage rates than 18-30 yrs old. Longer spinal cord injury duration increased usage by 0.98 times/year. Confidence using digital tools and positive health attitudes predicted usage. Comorbidities were positively correlated with usage. Concerns about digital health utilization had no significant impact., Conclusions: Our study provides one of the first comprehensive descriptions of digital health utilization in spinal cord injury. Its findings shed light on the intricate factors influencing digital health utilization, contribute to a deeper understanding of this patient population, and pave the way for more targeted and effective digital tools and strategies for their uptake., Competing Interests: Financial disclosure statements have been obtained, and no conflicts of interest have been reported by the authors or by any individuals in control of the content of this article., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objectives: Catheter-associated bloodstream infections (CABSI) cause preventable morbidity. We compared the microbiological etiology of CABSI across different types of central and peripherally-inserted catheters., Methods: We analyzed prospectively collected CABSI data in a 2100-bed hospital network in Switzerland between 2016 and 2022. We included: short-term non-tunneled central venous catheters (CVC); long-term catheters (tunneled, or peripherally-inserted central catheters); arterial catheters; dialysis catheters; and peripheral venous catheters (PVC). We used multivariable logistic regression models to describe the risk of Staphylococcus aureus and Gram-negative pathogens according to catheter type., Results: Overall, 416 CABSI episodes were included, including 60 episodes of S. aureus and 92 episodes of Gram-negative CABSI. Microbiological profiles differed between catheter types. Together, PVC and dialysis catheters accounted for 43/60 (72%) of all S. aureus CABSI. After adjusting for age, sex, and hematology/oncology care, the odds of S. aureus were higher for hemodialysis catheters (odds ratio [OR] 17.3, 95% confidence interval [CI] 5.75-52.2, P <0.01) and PVC (OR 2.96, 95% CI 1.22-7.20, P = 0.02) compared to short-term non-tunneled CVC. Odds of Gram-negative organism as the cause of CABSI were higher in long-term catheters versus short-term non-tunneled CVC (OR 2.70, 95% CI 1.37-5.24)., Conclusions: CABSI in catheters other than short-term non-tunneled CVC is more commonly caused by virulent organisms including S. aureus and Gram-negative bacteria. Catheter type should be considered when selecting empirical antimicrobial therapies., Competing Interests: Declarations of competing interest The authors have no competing interests to declare, (Copyright © 2024 The Authors.

We traced back a nationwide outbreak of human listeriosis in Switzerland to a persisting production line contamination of a factory producing baker's yeast with Listeria monocytogenes serotype 1/2a sequence type 3141. We used whole-genome sequencing to match clinical isolates to isolates from product samples.

Study Design: Retrospective cohort study., Objectives: This study aims to identify the prevalence, causes, time pattern and risk profile of rehospitalizations in persons with spinal cord injury (SCI) within a 10-year period following primary rehabilitation and identify most common secondary health conditions (SHCs) and risk profile leading to rehospitalizations., Setting: Specialized hospital and rehabilitation center for SCI in Switzerland., Methods: A retrospective analysis was conducted on clinical data from persons with SCI, discharged from initial rehabilitation between January 1, 2010, and December 31, 2012, and followed up over a period of ten years post-discharge. Descriptive statistical methods were utilized to compute the rehospitalization prevalence and to identify the primary reasons., Results: 225 participants were included, 70% were male (n = 179), and the mean age was 50 years (SD 19, Range 17-88). 54% were classified as having paraplegia (n = 122), and 77% incomplete injuries (n = 180). Over the 10-year observation period post-discharge, 120 were readmitted at least once, (prevalence 53%). In total, 66 persons (29%) were rehospitalized once or twice, while 54 persons (24%) were rehospitalized three or more times, with a maximum of 14 times. In the 10-year period, the most common SHCs leading to rehospitalization were infections (19%), pressure injuries (18%), and gastrointestinal problems (16%). During the study period, 57 persons (25%) passed away., Conclusions: Rehospitalization after primary rehabilitation is frequent and in the majority of the cases due to SHCs. The study findings are valuable for resource planning in healthcare and can guide the implementation of preventive measures to avoid SHCs., (© 2024.

Background: Passive exposure to cigarette smoke has negative effects on respiratory health. Childhood cancer survivors (CCS) are at increased risk for respiratory disease due to treatment regimens that may harm the respiratory system. The objective of this study was to assess the prevalence of parental smoking among CCS and investigate its association with respiratory outcomes., Procedure: As part of the Swiss Childhood Cancer Survivor Study, between 2007 and 2022, we sent questionnaires to parents of children aged ≤16 years who had survived ≥5 years after a cancer diagnosis. Parents reported on their children's respiratory outcomes including recurrent upper respiratory tract infections (otitis media and sinusitis), asthma, and lower respiratory symptoms (chronic cough persisting >3 months, current and exercise wheeze), and on parental smoking. We used multivariable logistic regression to investigate associations between parental smoking and respiratory outcomes., Results: Our study included 1037 CCS (response rate 66%). Median age at study was 12 years (interquartile range 10-14 years). Eighteen percent of mothers and 23% of fathers reported current smoking. CCS exposed to smoking mothers were more likely to have recurrent upper respiratory tract infections (OR 2.1; 95%CI 1.1-3.7) and lower respiratory symptoms (OR 2.0; 95%CI 1.1-3.7). We found no association with paternal smoking., Conclusions: A substantial proportion of CCS in Switzerland have parents who smoke. Exposure to maternal smoking was associated with higher prevalence of upper and lower respiratory problems. Healthcare providers can support families by addressing caregiver smoking behaviors and providing referrals to smoking cessation programs., (© 2024 The Author(s).

Background: The COVID-19 pandemic has led to significant disruptions in chronic disease care and forced people to stay at home. The effects of such issues on outpatients with lower extremity peripheral artery disease (PAD) remain unknown. Patients and methods: Single-centre, retrospective-prospective study conducted in a Swiss University Hospital. Patients with PAD were included between May 1 and July 31, 2020, with a follow-up visit at 12 months. Upon both visits, the Leriche-Fontaine PAD stage was recorded, and study participants underwent ankle-brachial index (ABI) calculation to assess limb perfusion. Functional capacities were assessed through the 6-minute walking and treadmill tests. Major adverse cardiovascular (MACE) and limb events (MALE) were recorded. Data collected during the pandemic were compared with the pre-pandemic period (January 1, 2019-April 30, 2020). Results: Overall, 259 patients were included. Mean age was 69 years and male sex was prevalent (69.1%). Odds of experiencing a degradation in PAD stage were lower during the pandemic than before (odds ratio [OR]: 0.43; 95% confidence interval [CI]: 0.21-0.87; p = 0.018). No significant difference was found between periods in terms of ABI trends. Both pain-free walking time at treadmill test (p = 0.003) and maximal pain intensity at 6-minute walking test (p = 0.001) significantly improved during the pandemic. Compared with the pre-pandemic period, during the pandemic patients were hospitalized less frequently (p = 0.028) and were less likely to undergo elective limb revascularization (p<0.001). No significant difference was found between periods in terms of MALE (p = 0.311), whereas non-fatal strokes were less frequently reported during the pandemic (p = 0.043). Conclusion: In a cohort of outpatients with PAD, we found no evidence of clinical deterioration during the pandemic compared with the pre-pandemic period, though rates of adverse events were nonnegligible in both periods. In case of future pandemics, patients with PAD should be encouraged to maintain an active lifestyle while being closely monitored to avoid clinical worsening.

Objectives: We aimed to determine the prevalence of HIV-related stigma among people with HIV (PWH) in Switzerland., Design: A cross-sectional multicenter study nested within the Swiss HIV Cohort Study (SHCS)., Methods: We included adult PWH enrolled in the SHCS, attending follow-up between March 1, 2020, and January 31, 2021. Inability to speak English, French, German, or Italian was the only exclusion criterion. Participants were invited to complete a validated 12-item HIV-stigma questionnaire comprising four stigma subscales (negative self-image, personalized stigma, disclosure concerns, and concerns regarding public attitudes), plus two healthcare-related stigma items. Questionnaire responses were graded using a four-point Likert-type scale, higher scores indicating higher stigma. "Non-applicable," inferring HIV-status non-disclosure, was possible for personalized stigma; stigma scores from participants answering "non-applicable" to at least one item were analyzed separately. Factors associated with HIV-stigma were identified through multivariable linear models., Results: Of 9643 PWH with a SHCS visit, 5563 participated in the study: 26% were female, 13% Black, and 37% heterosexual; median age was 53 years (interquartile range 44-59); 2067 participants (37%) gave at least one "non-applicable" response. Disclosure concerns had the highest stigma scores and were reported by 4656/5563 (84%). HIV-stigma was reported across all demographic groups. However, being female, Black, and heterosexual were independently associated with higher scores. Higher education and longer follow-up duration were associated with lower scores. Healthcare-related stigma was reported in 37% of participants., Conclusion: HIV-stigma was prevalent across all demographic groups. The association with being female and Black suggests that HIV-stigma accentuates preexisting sex and race inequalities., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

Introduction: Studies have shown a high prevalence of sleep-disordered breathing (SDB) in children with spina bifida. International standards for regular testing for SDB in this population are lacking. While there are studies investigating the prevalence of SDB in children with spina bifida, there are close to no studies in neonates., Aim and Objective: To evaluate if routine respiratory polygraphy (RPG) testing is indicated for neonates with spina bifida and if yes, with what therapeutic consequence., Methods: We conducted a retrospective cohort study of all neonates with spina bifida at the University (Children's) Hospital Zurich after fetal spina bifida repair born between 2017 and 2022, who had undergone at least 1 RPG evaluation during hospitalization on the neonatal ward. RPG were evaluated by a blinded group of experienced pediatric pulmonologists. Based on the neonatal RPG results and pediatric pulmonologist's recommendation for caffeine therapy the spina bifida cohort was divided into two groups. Neonatal baseline RPG and follow-up RPG at the age of the 3 months were evaluated., Results: 48 neonates with RPG were included. Compared to the standard values in healthy neonates, the RPG results of this spina bifida cohort showed findings of SDB with central apnea and hypopnea. 22 (45.8%) neonatal RPG evaluations detected central SDB, prompting caffeine therapy. Follow-up RPG conducted after 3 months showed significant improvement of SDB with (almost) no need for continuation of caffeine., Conclusion: We recommend the implementation of routine RPG testing in neonates with spina bifida to detect SDB and facilitate early targeted treatment., (© 2024 The Author(s).

Introduction: Pharmacoepidemiological data suggest that lithium prescriptions for bipolar disorder are gradually decreasing, with less attention having been paid to other indications., Methods: We examined lithium prescriptions between 1994 and 2017 in data provided by the Drug Safety in Psychiatry Program AMSP, including psychiatric hospitals in Germany, Austria and Switzerland. We compared lithium use for different diagnoses before and after 2001 and in three periods (T1: 1994-2001, T2: 2002-2009, and T3: 2010-2017)., Results: In a total of 158,384 adult inpatients (54% female, mean age 47.4±17.0 years), we observed a statistically significant decrease in lithium prescriptions between 1994-2000 and 2001-2017 in patients with schizophrenia spectrum disorder from 7.7% to 5.1% and in patients with affective disorders from 16.8% to 9.6%. Decreases in use were also observed for diagnostic subgroups: schizoaffective disorder (ICD-10 F25: 27.8% to 17.4%), bipolar disorder (F31: 41.3% to 31%), depressive episode (F32: 8.1% to 3.4%), recurrent depression (F33: 17.9% to 7.5%, all: p<0.001) and emotionally unstable (borderline) personality disorder (6.3% to 3.9%, p=0.01). The results in T1 vs. T2 vs. T3 were for F25: 26.7% vs. 18.2% vs. 16.2%, F32: 7.7% vs. 4.2% vs. 2.7%, F33: 17.2% vs. 8.6% vs. 6.6% and for F31: 40.8% vs. 31.7% vs 30.0%, i. e. there was no further decrease for lithium use in bipolar disorder after 2002. Lithium's main psychotropic co-medications were quetiapine (21.1%), lorazepam (20.6%), and olanzapine (15.2%)., Discussion: In inpatients, the use of lithium has decreased in patients with bipolar disorder and also with various other psychiatric diagnoses., Competing Interests: Competing interests S.

Introduction: In the context of adverse in utero environments, the fetal brain might be preserved at the expense of other tissues. This trade-off, brain sparing, has not been studied in the context of maternal infection. We investigated cases of maternal syphilis in the early 20th century and influenza during the 1918-1920 pandemic, in the Swiss city of Lausanne, a relatively high-income setting. We tested the brain sparing hypothesis, that head circumference is protected at the expense of birth weight., Methods: A total of 8530 individual birth records from 1911 to 1922 from the University Maternity Hospital of Lausanne were used. We fitted generalized linear and additive linear models to explain how neonatal size varies under disease exposure., Results: Influenza reduced head circumference and birth weight among livebirths similarly, by -0.11 and -0.14 standard deviation (SD) units respectively. Conversely, for syphilis-exposed infants, head circumference was affected more than birth weight (-0.61 SD vs. -0.46 SD). Stillborn infants exposed to syphilis experienced a much greater reduction in head circumference (-1.92 SD) than liveborn infants. After adjustment for gestational age, these findings persisted in the case of influenza, but the effects of syphilis were reduced. Furthermore, half of syphilis-exposed infants were born before term, suggesting that lower infant size was partly mediated by shorter gestation. Nevertheless, head circumference among stillbirths exposed to syphilis was still substantially reduced, even after adjustment for gestational age (-1.26 SD)., Conclusion: Our findings do not support the brain sparing hypothesis. Moreover, the substantial reduction in head circumference among syphilis-exposed fetuses might help explain why a quarter of them were stillborn., (© 2024 The Author(s).

While Switzerland has not yet established a systematic approach, the small size of the country and the intensive collaboration between the transplant infectious disease teams facilitate a rapid communication once a donor-derived infection is suspected. Critical information regarding donor infections is shared rapidly, and appropriate measures are discussed. The long-term observational Swiss Transplant Cohort Study, which includes >92% of all solid organ recipients collects all relevant infectious disease episodes and facilitates detection of patterns of potential donor-derived infection., (© 2024 The Author(s).

Background: Data describing outcome of extracorporeal membrane oxygenation (ECMO) support in Tuberculosis (Tbc)-associated acute respiratory distress syndrome (ARDS) remain sparce and are mostly confined to singular case reports. The aim of this case series was to analyze intensive care unit (ICU) survival in patients with Tbc-associated ARDS receiving veno-venous (vv-) ECMO support and to compare those to patients not receiving ECMO., Case Presentation: ICU survival was analyzed retrospectively in 14 patients treated for Tbc-associated ARDS at three ECMO-referral university hospitals (Hannover Medical School, University Hospital Bonn (both Germany) and University Hospital Zurich (Switzerland)) during the last 14 years, of which eight patients received additional vv-ECMO support and six standard care only. ICU survival was significantly higher in patients receiving additional vv-ECMO support (62.5%, n = 5/8) compared to those that did not (16.7%, n = 1/6) (p = 0.021). ECMO support was associated with reduced ICU mortality (Hazard ratio adjusted for baseline SOFA score [adj. HR] 0.125 (95% confidence interval (CI): 0.023-0.689), p = 0.017). Median (IQR) time on ECMO and invasive ventilation in the vv-ECMO group were 20 (11-26) and 37 (27-53) days, respectively. Major bleeding defined as transfusion requirement of 4 units of blood or more or surgical and/or radiologic intervention occurred only in one patient, in whom pulmonary bleeding was fatal. Thromboembolic events occurred in none of the vv-ECMO patients., Discussion and Conclusions: This retrospective analysis from three large ECMO centers with similar SOPs suggests vv-ECMO support as a feasible approach in patients with severe Tbc-associated ARDS. Although affiliated with extended runtimes, vv-ECMO might be associated with improved survival in those patients. Vv-ECMO support should thus be considered in Tbc-associated ARDS to enable lung protective strategies during prolonged lung recovery., (© 2024. The Author(s).)

Background: We evaluated long-term trajectories of circulating hepatitis B virus (HBV) RNA and hepatitis B core-related antigen (HBcrAg) in persons with and without hepatitis B surface antigen (HBsAg) loss during tenofovir therapy in the Swiss HIV Cohort Study., Methods: We included 29 persons with HIV with HBsAg loss and 29 matched persons with HIV without HBsAg loss. We compared HBV RNA and HBcrAg decline and assessed the cumulative proportions with undetectable HBV RNA and HBcrAg levels during tenofovir therapy using Kaplan-Meier estimates., Results: HBsAg loss occurred after a median of 4 years (IQR, 1-8). All participants with HBsAg loss achieved suppressed HBV DNA and undetectable HBV RNA preceding undetectable quantitative HBsAg levels, whereas 79% achieved negative HBcrAg. In comparison, 79% of participants without HBsAg loss achieved undetectable HBV-RNA and 48% negative HBcrAg. After 2 years of tenofovir therapy, an HBV RNA decline ≥1 log10 copies/mL had 100% sensitivity and 36.4% specificity for HBsAg loss, whereas an HBcrAg decline ≥1 log10 U/mL had 91.0% sensitivity and 64.5% specificity., Conclusions: HBV RNA suppression preceded undetectable quantitative HBsAg levels and had high sensitivity but low specificity for HBsAg loss during tenofovir therapy in persons with HIV. HBcrAg remained detectable in approximately 20% of persons with HBsAg loss and 50% of persons without HBsAg loss., Competing Interests: Potential conflicts of interest. L.

Q fever (QF) and Rift Valley fever (RVF) are endemic zoonotic diseases in African countries, causing significant health and economic burdens. Accurate prevalence estimates, crucial for disease control, rely on robust diagnostic tests. While enzyme-linked immunosorbent assays (ELISA) are not the gold standard, they offer rapid, cost-effective, and practical alternatives. However, varying results from different tests and laboratories can complicate comparing epidemiological studies. This study aimed to assess the agreement of test results for QF and RVF in humans and livestock across different laboratory conditions and, for humans, different types of diagnostic tests. We measured inter-laboratory agreement using concordance, Cohen's kappa, and prevalence and bias-adjusted kappa (PABAK) on 91 human and 102 livestock samples collected from rural regions in Chad. The serum aliquots were tested using ELISA in Chad, and indirect immunofluorescence assay (IFA) (for human QF and RVF) and ELISA (for livestock QF and RVF) in Switzerland and Germany. Additionally, we examined demographic factors influencing test agreement, including district, setting (village vs. camp), sex, age, and livestock species of the sampled individuals. The inter-laboratory agreement ranged from fair to moderate. For humans, QF concordance was 62.5%, Cohen's kappa was 0.31, RVF concordance was 81.1%, and Cohen's kappa was 0.52. For livestock, QF concordance was 92.3%, Cohen's kappa was 0.59, RVF concordance was 94.0%, and Cohen's kappa was 0.59. Multivariable analysis revealed that QF test agreement is significantly higher in younger humans and people living in villages compared to camps and tends to be higher in livestock from Danamadji compared to Yao, and in small ruminants compared to cattle. Additionally, RVF agreement was found to be higher in younger humans. Our findings emphasize the need to consider sample conditions, test performance, and influencing factors when conducting and interpreting epidemiological seroprevalence studies., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Hungerbühler et al.

Background: Since the implementation of universal antiretroviral therapy, kidney transplantation (K-Tx) has become a valuable option for treatment of end-stage kidney disease for people with HIV (PWH) with similar patient and graft survival as compared to HIV-uninfected patients. Little is known about the hazards and manifestations of infectious disease (ID) events occurring in kidney transplant recipients with HIV., Methods: Using linked information collected in the Swiss HIV Cohort Study (SHCS) and the Swiss Transplant Cohort Study (STCS), we described in-depth demographical and clinical characteristics of PWH who received a K-Tx since 2008. Further, we performed recurrent time to event analyses to understand whether HIV was an independent risk factor for ID events., Results: Overall, 24 PWH with 57 ID events were included in this study (100% match of SHCS to STCS). Of these, 17 (70.8%) patients had at least one ID event: 22 (38.6%) viral (HIV not counted), 18 (31.6%) bacterial, one (1.8%) fungal and 16 (28.1%) probable infections. Most ID events affected the respiratory tract (25, 37.3%) or the urinary tract (13, 19.4%). Pathogen types and infection sites were similar in PWH and a matched control group of HIV-uninfected patients. HIV was not an independent risk factor for ID events (adjusted hazard ratio 0.94, p = 0.9)., Conclusion: By linking data from two large national Swiss cohorts, we provided in-depth information on ID events in PWH receiving a K-Tx in Switzerland. HIV infection was not associated with an increased hazard for ID events after K-Tx., (© 2024. The Author(s).)

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.

Botulism is a neuro-paralytic syndrome caused by the production of a neurotoxic protein by Clostridium botulinum. It is a rare but potentially fatal poisoning. Symptoms are due to blockage of neurotransmitter release at the neuromuscular junction. Botulism usually occurs following ingestion, inhalation or contact of the toxin with a wound. More recently, cases of iatrogenic botulism have been described, notably following the injection of toxin for therapeutic or cosmetic purposes. In spring 2023, an outbreak of iatrogenic botulism following intragastric injections was reported in Europe. Here, we provide an overview of botulism, followed by a presentation of the only two Swiss cases reported during the epidemic., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

For several years, there has been increasing awareness of a novel tick-borne infection within our region: neoehrlichiosis. The causative agent, Neoehrlichia mikurensis , is an intracellular bacterium classified within the Anaplasmataceae family. Predominantly afflicting immunosuppressed individuals, its clinical presentation often involves persistent fever accompanied by vascular complications. Diagnostic protocols typically entail targeted PCR testing of blood specimens, often leading to diagnostic delays. Timely initiation of doxycycline therapy typically ensures prompt resolution of symptoms., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Background: Kawasaki disease is a rare systemic inflammatory syndrome that mainly affects children under five years of age and is the first cause of pediatric acquired cardiovascular disease. The pathogenesis is complex and a viral trigger is suspected, as well as genetic susceptibility. Multiple studies around the world have shown a decrease in the incidence of Kawasaki disease and have hypothesized that the different sanitary measures enforced in each country during the pandemic period could be responsible to a certain extent. The aim of this study is to evaluate the effects of the COVID-19 pandemic on the disease's incidence, defining characteristics, coronary artery outcomes and management in a tertiary center in Switzerland., Methods: This study is a retrospective analysis of children who have been diagnosed with Kawasaki disease that compares clinical, laboratory, SARS-CoV-2 exposure, and echocardiographic data as well as treatments before (January 1st 2017 to February 24th 2020) and during (February 25th 2020 to December 31st 2022) the COVID-19 pandemic in Switzerland. Statistical significance of differences in the compared parameters was assessed., Results: Of the 90 patients included, 31 belonged to the first group and 59 belonged to the second group. There was a statistically significant (p < 0.05) increase in incidence during the pandemic period (5.91/100,000 children) of 88% compared to the pre-pandemic period (3.14/100,000 children). A lesser seasonal variation was observed during the pandemic. 30% of the patients in the pandemic group had an exposure to SARS-CoV-2. There was no other notable difference in demographic factors, clinical presentation, coronary outcome or administered treatment., Conclusions: To the best of our knowledge, this is the first prolonged European study comparing Kawasaki disease before and during the COVID-19 pandemic. There was a significant increase in incidence in Kawasaki disease during the COVID-19 pandemic. In contrast, studies done in Japan, South Korea and the USA have shown a decrease in incidence. Differences in methodologies, genetics, ethnicities, environments, microbiome-altering behaviors, sanitary measures and SARS-CoV-2 spread are factors that should be considered. Further studies analyzing the differences between countries with increased incidence of Kawasaki disease could help better understand the relevance of such factors and provide more insight into the etiologies of this particular disease., (© 2024.

Background: The ageing of the population is leading to an increase in the number of traumatic injuries and represents a major challenge for the future. Falls represent the leading cause of Emergency department admission in older people, with injuries ranging from minor to severe multiple injuries. Older injured patients are more likely to be undertriaged than younger patients. The aim of this study was to investigate the extent of undertriage in older patients with particular emphasis on access to trauma centres and resuscitation rooms., Methods: Retrospective observational cross-sectional study based on data prospectively collected from prehospital electronic records including all patients ≥ 18 years for whom an ambulance or helicopter was dispatched between 1 January 2018 and 31 April 2023 due to a trauma. The primary outcome, admission to the resuscitation room of the regional trauma centre with trauma team activation, was assessed by age. Multivariate logistic regression was used to control for known confounders and to test for plausible effect modifiers., Results: Emergency Medical Services treated 37,906 injured patients. Older patients ≥ 75 years represented 17,719 patients (47%). Admission to trauma centre with trauma team activation was lower in older patients, N = 121 (1%) compared to N = 599 (5%) in younger patients, p < 0.001; adjusted odds ratio: 0.33 (0.24-0.45); p < 0.001. Undertriage increased by twofold with age ≥ 75; OR: 1.81 (1.04-3.15); p value < 0.001. Undertriaged patients were older, more likely to be female, to have low energy trauma and to be located farther from the regional trauma centre., Conclusion: Older injured patients were at increased risk of undertriage and non-trauma team activation admission, especially if they were older, female, had head injury without altered consciousness and greater distance to regional trauma centre., (© 2024.

Background: Increasing nosocomial infections during the COVID-19 pandemic have been reported. However, data describing peripheral venous catheter associated bloodstream infections (PVC-BSI) are limited., Aims: To describe the epidemiology and risk factors for PVC-BSI during the COVID-19 pandemic., Methods: We conducted retrospective cohort study of prospectively collected PVC-BSI data in a 2100 bed hospital network in Switzerland. Adult patients with a PVC inserted between January 1, 2020 and December 31, 2021 were included. Risk factors for PVC-BSI were identified through descriptive analysis of patient and catheter characteristics, and univariable marginal Cox models., Results: 206,804 PVCs and 37 PVC-BSI were analysed. Most PVC-BSI were attributed to catheters inserted in the Emergency department (76%) or surgical wards (22%). PVC-BSI increased in 2021 compared to 2020 (hazard ratio 2021 vs. 2020 = 2.73; 95% confidence interval 1.19-6.29), with a numerically higher rate of Staphylococcus aureus (1/10, 10%, vs. 5/27, 19%) and polymicrobial infection (0/10, 0% vs. 4/27, 15%). PVC insertions, patient characteristics, and catheter characteristics remained similar across the study period. PVC-BSI risk was associated with admission to the intensive care unit (ICU), and use of wide gauge catheter ( < = 16G)., Conclusion: Increased PVC-BSI during the COVID-19 pandemic was not explained by catheter or patient factors alone, and may result from system-wide changes. PVC-BSI events are primarily attributed to acute care settings, including the emergency department, surgical wards, and the ICU., (© 2024. The Author(s).)

Objectives: We assessed the relationship between heat and emergency hospital admissions (EHAs) in Switzerland using clinically relevant metrics., Methods: Applying distributed lag non-linear models, we investigated temperature-admission associations between May and September 1998-2019 for various disease groups, by age class and gender. We estimated the relative risk (RR) for moderate (29°C) and extreme (34°C) daily maximum temperatures relative to disease-specific optimum temperature, and calculated attributable fractions (AFs) for hot days and the following week. We also calculated the total number of heat-related EHAs., Results: We attributed 31,387 (95% confidence interval: 21,567-40,408) EHAs to above-optimal temperatures, 1.1% (0.7%-1.4%) of the total. Extreme temperatures increased the EHA risk for mental, infectious and neurological diseases. We observed particularly high AFs due to extreme heat for dehydration (85.9%, 95% CI: 82.4%-88.8%) and acute kidney injury (AKI, 56.1%, 95% CI: 45.3%-64.7%). While EHA risk generally increased with age, we also found high RRs for infectious diseases in children (0-15 years) and AKI in young adults (15-64 years)., Conclusion: Hot weather increases the EHA risk in Switzerland. Therefore a comprehensive clinical and public health response is needed., Competing Interests: The authors declare that they do not have any conflicts of interest., (Copyright © 2024 Schulte, Röösli and Ragettli.)

Background: Radical prostatectomies can be performed using open retropubic, laparoscopic, or robot-assisted laparoscopic surgery. The literature shows that short-term outcomes (in particular, inpatient complications) differ depending on the type of procedure. To date, these differences have only been examined and confirmed in isolated cases based on national routine data., Methods: The data was based on the Swiss Medical Statistics from 2016 to 2018 from a national survey of administrative data from all Swiss hospitals. Cases with the coded main diseases neoplasm of the prostate (ICD C61) and the main treatments of laparoscopic (CHOP 60.5X.20) or retropubic (CHOP 60.5X.30) radical prostatectomies were included, resulting in a total sample size of 8,593 cases., Results: A procedure-related complication occurred in 998 cases (11.6%). By surgical procedure, complication rates were 10.1% for robotic-assisted laparoscopic radical prostatectomy 9.0% for conventional laparoscopic radical prostatectomy and 17.1% for open retropubic radical prostatectomy (p < 0.001). Conventional and robotic-assisted laparoscopic radical prostatectomies had a significantly lower risk of complications than retropubic procedures. Moreover, the risk of a procedure-related complication was almost twice as high in cases operated on retropubically; however, no significant difference was found between conventional and robotic-assisted laparoscopic cases., Discussion: The use of a surgical robot showed no advantages in radical prostatectomies regarding procedure-related during the hospital stay. However, both conventional and robotic-assisted laparoscopically operated radical prostatectomies show better results than open retropubic procedures. Further studies on the long-term course of patients based on claims data are needed to confirm the inherent benefits of surgical robots in tandem with them being increasingly employed in hospitals., (© 2024.

Aims of the Study: Spinal muscular atrophy (SMA) is a degenerative neuromuscular disorder leading to muscle hypotonia, weakness, and respiratory and bulbar impairment. Infants with SMA have an increased risk of respiratory tract infections (RTI) including severe respiratory syncytial virus (RSV) infections. Therefore, guidelines for the treatment of SMA recommend RSV prophylaxis with palivizumab for patients aged below two years who have compromised motor functions ("non-sitters"). Since palivizumab is not approved for RSV prophylaxis in SMA patients in Switzerland, payers usually do not grant cost approvals for this indication. Therefore, this study aimed to investigate the frequency of severe RTI among SMA patients focusing on RSV infections requiring hospital treatment and to determine the long-term impact of RSV infections on the natural history of SMA., Methods: A single-centre cohort study at the tertiary paediatric Neuromuscular Centre Zurich, Switzerland, including data of SMA patients with a genetic-based therapy initiated below two years of age between May 2019 and December 2022. All hospitalisations were analysed with a focus on severe RTI and especially RSV infections, and their impact on nutritional and respiratory function. The costs of inpatient treatment of RSV infections were determined and compared with estimated expenses for RSV prophylaxis with palivizumab., Results: 12 SMA patients (median age at treatment initiation: 3.5 months, range: 0-17 months) were followed for a cumulative period of 25.75 years (7 SMA type 1; 5 SMA type 2 including one presymptomatic individual). With an incidence rate of 2.34 per patient-year, the risk of severe RTI was especially high in SMA type 1 (versus 0.1 in SMA type 2, p = 0.044). A total of 37 hospitalisations (279 hospital days) was necessary for the treatment of RTI in general; 9 of them were attributed to RSV infections (in 5 SMA type 1 patients; 84 hospital days). Only 3/12 SMA patients had received seasonal RSV prophylaxis with palivizumab. No RSV infections requiring hospital treatment occurred in patients while receiving seasonal RSV prophylaxis. During RTI, nutritional support had to be commonly initiated and continued after discharge. In 3/7 SMA type 1 patients, non-invasive ventilation was started during acute treatment for RTI and continued to the end of follow-up., Conclusion: We observed a high risk of RTI, especially RSV infections, among young SMA patients. Failure to adhere to established care protocols, for example by omitting RSV prophylaxis, may be linked to a heightened risk of morbidity in these children.

Background: Swiss climate scenarios predict increases in the frequency and intensity of extreme heat episodes in the future. For the effective prevention of heat-related mortality, several aspects of the population's vulnerability to heat must be understood on a local level., Methods: A nationwide analysis of individual death records was conducted, enabling a more comprehensive understanding than typical heat studies based on aggregated data. A total of 320,306 individual death records from the Swiss National Cohort with precise address information during the warm season (May to September) from 2003-2016 were linked to indoor and outdoor high-resolution daily temperature estimates. A time-stratified case-crossover study combined with distributed lag non-linear models was then performed to assess the temperature-mortality associations for various causes of death and to estimate the potential effect modification of individual characteristics. Additionally, it was explored whether the effect of extreme heat changed over time in regions with and without cantonal heat-health action plans (HHAPs)., Results: Using the temperature with the lowest cause-specific mortality risk (minimum mortality temperature) as the reference temperature, extreme heat (defined as ambient daily maximum temperature reaching 33 °C) was associated with a strong increase in all-cause mortality (odds ratio (OR): 1.21, 95% CI: 1.17-1.25) and disease-specific mortality from Alzheimer's disease and dementia (OR: 1.67, 95% CI: 1.48-1.88), COPD (OR: 1.37, 95% CI: 1.12-1.67), diabetes (OR: 1.34, 95% CI: 1.06-1.70), and myocardial infarction (OR: 1.26, 95% CI: 1.10-1.44). Indoor temperatures above 24 °C were found to be critical for mortality. The population most vulnerable to heat included older adults (≥75 years), unmarried individuals, people with a low education level, older women with low neighbourhood socioeconomic position, and men under 75 years old with low socioeconomic position. Overall, the risk of heat-related all-cause mortality in 2009-2016 was lower than that in 2003-2008. The decrease was significantly stronger in the region where cantonal HHAPs were implemented., Conclusions: This study provides important information for planning targeted and effective measures to reduce heat-related health risks in Switzerland. It demonstrates that HHAPs contribute to reducing heat-related mortality, although they may not reach the high-risk population of individuals with low socioeconomic position. Future prevention efforts should also target the less privileged population, including people younger than 75 years.

Background: Postoperative delirium (POD) significantly impacts older surgical patients, necessitating effective prevention strategies., Objective: To assess the effectiveness of the Pre-Interventional Preventive Risk Assessment (PIPRA) automated delirium risk prediction tool alongside non-pharmacological prevention strategies on POD incidence, hospital length of stay (LOS) and nursing time., Methods: This quality improvement project, set in a 335-bed Swiss private hospital, employed a before-after design to evaluate the impact of PIPRA and preventive measures on POD, LOS and nursing time in non-cardiac and non-intracranial surgery inpatients aged 60 or older. The control phase focused on enhancing POD screening, whilst the intervention phase incorporated PIPRA for risk assessment and staff training to enable targeted non-pharmacological prevention in patients at risk., Results: A total of 866 patients were included; 299 control and 567 intervention. The odds ratio of POD, comparing the intervention group to the control, was 0.71 [95% confidence interval (CI) 0.44-1.16] when adjusting for baseline patient characteristics. The intervention was associated with an LOS 0.94 (95% CI 0.85-1.05) and nursing time 0.96 (95% CI 0.86-1.07) times that of the control, adjusted for baseline patient characteristics. Medium risk patients (21.6% of patients) had an LOS 0.74 (95% CI 0.59-0.92) and required nursing time 0.79 (95% CI from 0.62-1.00) times the control, adjusted for baseline patient characteristics, equivalent to an LOS reduction of 1.36 days and nursing time saving of 19.3 hours per patient., Conclusions: Medium risk patients in the intervention group had shorter LOS and nursing time compared to the control group, underscoring the importance of targeted prevention., (© The Author(s) 2024.

Real-world data on anatomically localized psoriasis and its response to systemic therapy across different age-groups and sexes is limited. This study aimed to evaluate the severity and distribution of psoriasis over time in female and male patients receiving systemic therapies, categorized by age within the Swiss psoriasis registry (SDNTT). Patient-data was obtained over 11 years through the SDNTT. The localized Psoriasis Area and Severity Index (locPASI) of the head, trunk, upper and lower extremities was analyzed over two years following the start of systemic non-/biologic treatment. A total of 316 female and 517 male patients were analyzed. Male patients had a higher baseline locPASI for legs, trunk and arms (p < 0.001), but not for the head (p = 0.961). The locPASI for the head in younger female patients (18-40 years) had a higher score than those aged 55 + (p = 0.022) and after two years, middle aged (41-54) showed a lower score compared to younger patients (p = 0.045). Younger male patients revealed a lower score after two years of therapy in the leg- and arm-area compared to older (p = 0.018 and p = 0.048, respectively). Female patients on non-biologics had a fast initial response, converging with male patients' scores over 24 months. Over 75% locPASI reduction was observed for female head-area (81.4%), male trunk (82.7%) and legs (76.1%). Absolute locPASI ≤ 2 was achieved 3-6 months for all locations with interleukin (IL)-17, IL-12/23 and IL-23-inhibitors, except for the legs of male patients on anti-IL-17 and female patients on anti-IL-12/23 and -IL-23. After two years, male patients did not achieve a locPASI ≤ 2 for any biologic-treatment in the legs, nor for the arms on anti-TNF-α. Significant disparities in localized PASI were observed between female and male patients. The age, sex and severity of distinct localizations should be considered to optimize treatment goals., (© 2024. The Author(s).)

Background: Switzerland is one of the few remaining European countries without a uniform national breast cancer screening program. Most Swiss cantons have initiated mammography screening programs, with the notable exceptions of the cantons of central Switzerland. The aim of this study is to compare the TNM (tumor-node-metastasis) status in woman diagnosed with screen- and non-screen-detected breast cancers. We compare TNM of breast cancers of cantonal screening cantons (Or-SC) with organized mammographic screening and opportunistic-screening cantons (Op-SC) without organized mammographic screening., Materials and Methods: We compared the TNM documented in cantons with organized screening (Or-SC) in the national cancer registry with those in the cantons of central Switzerland without organized screening (Op-SC) between 2014 and 2020. Since 2014, a total of 19 236 patients from Or-SC and 2282 from Op-SC with breast cancer were compared. Age groups were defined as younger than 50 years, between 50 and 69 years, and older than 70 years., Results: By comparison, women aged 50-69 years in the cantons of the Op-SC group exhibited significantly larger tumors T1-3 [point estimate of the difference with 95% confidence interval (CI) for T1: -7.7% (95% CI -11.0% to -4.4%); T2: 5.3% (95% CI 2.2% to 8.5%); T3: 2.5% (95% CI 0.8% to 4.2%)] and significantly fewer proportion of N0 [-5.7% (95% CI -9.0% to -2.5%)] without significant difference in the M status (P = 0.97)., Conclusion: Our study shows that patients aged 50-69 years from Op-SC have significantly larger tumors and higher incidence of lymph node metastases than women in the corresponding Or-SC group. This globally unique case within one single small country with very high living standards, but with different screening strategies, indicates the benefits of organized breast screening programs., (Copyright © 2024 The Author(s).

We assessed the trends, characteristics, and consequences of potentially avoidable hospitalizations (PAH) for hypertension in Switzerland, for the period 1998 to 2018. Data from 117,507 hospitalizations (62.1% women), minimum age 20 years. Hospitalizations with hypertension as the main cause for admission were eligible. PAH for hypertension was defined according to the Organization for Economic Cooperation and Development criteria. The age-standardized rates of PAH for hypertension increased from 43 in 1998 to 81 per 100,000 in 2004, to decrease to 57 per 100,000 inhabitants in 2018. Compared to non-PAH, patients with PAH for hypertension were younger, more frequently women (66.9% vs. 56.7%), non-Swiss nationals (15.9% vs. 10.9%), were more frequently admitted as an emergency (78.9% vs. 59.5%), and by the patient's initiative (33.1% vs. 14.1%). Patients with PAH had also fewer comorbidities, as per the Charlson's index. Patients with PAH for hypertension were more frequently hospitalized in a semi-private or private setting, stayed less frequently in the intensive care unit (4.6% vs. 7.3%), were discharged more frequently home (91.4% vs. 73.0%), and had a shorter length of stay than patients with non-PAH for hypertension: median and [interquartile range] 5 [3-8] vs. 9 [4-15] days. In 2018, the total costs of PAH were estimated at 16.5 million CHF, corresponding to a median cost of 4936 [4445-4961] Swiss Francs per stay. We conclude that in Switzerland, PAH have increased, represent a considerable fraction of hospitalizations for hypertension, and carry a non-negligible health cost., (© 2024. The Author(s).)

Previous research investigated the trajectories of mental health and well-being during and after the onset of the COVID-19 pandemic. However, less is known about the trajectories of mental health and well-being before, during, and two years after the onset of the pandemic. The aim of the current study was to investigate the trajectory of depression symptoms and subjective well-being (i.e., life satisfaction and positive and negative affect) trajectories over six time points (2017-2022), three before the pandemic and three after the onset of the pandemic. To increase the robustness of our overall conclusions and avoid reliance on data from only one country, we used data from two nationwide representative longitudinal surveys conducted in Germany (GESIS Panel study; N = 5184) and Switzerland (Swiss Household Panel study; N = 17,074). Using covariance pattern mixture models, the results revealed that a four-class model best fit the data. The Stable/resilient trajectory was the most common across outcomes (74.2%-90.1% of participants). Three additional trajectories of Chronic/Low, Upright U-shaped, and Inverted U-shaped emerged in the analysis of negative affect and depression symptoms, while distinct trajectory classes of Worsening, Improving/Stable, and Upright U-shaped also emerged for analyses of positive affect and life satisfaction shaped. In conclusion, there was no evidence of a long-term impact of the pandemic for the vast majority of participants (about 90%). For the remaining participants, the COVID-19 pandemic (along with its exceptional circumstances) was a turning point or a catalyst that reversed, accelerated, or flattened a pre-pandemic trend. These changes in trends were not only negative (e.g., greater depression symptoms), but also positive (e.g., less depression symptoms)., Competing Interests: Declaration of competing interest We have no conflicts of interest to disclose., (Copyright © 2024 The Author(s).

Background and Aims: Dysphagia is the hallmark symptom in eosinophilic esophagitis (EoE). However, data are limited regarding the overall prevalence and potential implications of atypical symptoms like odynophagia and retrosternal pain., Methods: Patients enrolled into the Swiss EoE cohort study (SEECS) were analyzed regarding the presence of odynophagia and retrosternal pain. Demographics, other EoE-related symptoms, histologic and endoscopic activity were compared between EoE-patients with vs. without odynophagia and/or retrosternal pain., Results: 474 patients (75.2% male) were analyzed. In their individual course of disease 110 (23.2%) patients stated to have ever experienced odynophagia and 64 (13.5%) retrosternal pain independent of food intake, 24 (5%) patients complained about both symptoms. Patients with odynophagia consistently scored higher in symptom severity (p < 0.001), EREFS score (median 3.0 vs. 2.0, p = 0.006), histologic activity and a lower quality of life (p = 0.001) compared to patients without odynophagia. Sex, age at diagnosis, EoE-specific treatment, complications such as candida or viral esophagitis and disease duration were similar in patients with vs. without odynophagia. Also patients with retrosternal pain scored higher in symptom severity (2.0 vs. 1.0, p = 0.001 and 2.0 vs. 1.0, p < 0.001 in physician and patient questionnaire assessment, respectively). However, there was neither a difference in endoscopic/histologic disease activity nor in quality of life according to presence or absence of retrosternal pain. Due to logistic reasons, a stratification regarding the presence of concomitant dysphagia was not possible., Conclusion: Odynophagia and swallowing-independent retrosternal pain are common symptoms in patients with EoE, associate with an overall higher EoE-related symptom severity and for the case of odynophagia lower quality of life. However, the influence of concomitant dysphagia and its severity remains unclear and needs to be included in future analyses., (© 2024. The Author(s).)

Purpose: Given the increased cardio-metabolic risk in patients with acromegaly, this study compared cardiovascular outcomes, mortality, and in-hospital outcomes between patients with acromegaly and non-functioning pituitary adenoma (NFPA) following pituitary surgery., Methods: This was a nationwide cohort study using data from hospitalized patients with acromegaly or NFPA undergoing pituitary surgery in Switzerland between January 2012 and December 2021. Using 1:3 propensity score matching, eligible acromegaly patients were paired with NFPA patients who underwent pituitary surgery, respectively. The primary outcome comprised a composite of cardiovascular events (myocardial infarction, cardiac arrest, ischemic stroke, hospitalization for heart failure, unstable angina pectoris, cardiac arrhythmias, intracranial hemorrhage, hospitalization for hypertensive crisis) and all-cause mortality. Secondary outcomes included individual components of the primary outcome, surgical re-operation, and various hospital-associated outcomes., Results: Among 231 propensity score-matched patients with acromegaly and 491 with NFPA, the incidence rate of the primary outcome was 8.18 versus 12.73 per 1,000 person-years (hazard ratio [HR], 0.64; [95% confidence interval [CI], 0.31-1.32]). Mortality rates were numerically lower in acromegaly patients (2.43 vs. 7.05 deaths per 1,000 person-years; HR, 0.34; [95% CI, 0.10-1.17]). Individual components of the primary outcome and in-hospital outcomes showed no significant differences between the groups., Conclusion: This cohort study did not find an increased risk of cardiovascular outcomes and mortality in patients with acromegaly undergoing pituitary surgery compared to surgically treated NFPA patients. These findings suggest that there is no legacy effect regarding higher cardio-metabolic risk in individuals with acromegaly once they receive surgical treatment., (© 2024.

Background: The association between dairy intake and prevalence or incidence of hypertension remains controversial. We aimed to investigate the association between intake of different dairy products and prevalence and incidence of hypertension in a community-dwelling sample., Methods: Three cross-sectional studies (2009-12, 2014-17 and 2018-21) and one prospective study (2009-12 to 2018-21) were conducted in Lausanne, Switzerland. Dietary intake was assessed via a validated food frequency questionnaire. Dairy consumption was compared between participants with and without prevalent or incident hypertension., Results: For the cross-sectional analyses, data from 4437 (2009-12, 54.0% women, 57.7 ± 10.5 years), 2925 (2014-17, 53.4% women, 62.5 ± 10.0 years), and 2144 (2018-21; 53.3% women, 65.5 ± 9.6 years) participants were used. No consistent differences between participants with and without hypertension were found for all dairy products (total dairy, milk, yogurt, cheese, low-fat dairy, and full-fat dairy) although participants with hypertension tended to consume less cheese (51 ± 1 vs. 55 ± 1, p = 0.014, 52 ± 1 vs. 56 ± 1, p = 0.053, and 54 ± 1 vs. 56 ± 1 g/day for 2009-12, 2014-17 and 2018-21, respectively). For the prospective study, data from 2303 participants (60.8% women, 53.9 ± 9.0 years) were used. Irrespective of the dairy product considered, no association was found between quartiles of dairy consumption and development of hypertension. Similar findings were obtained after stratifying on dietary quality., Conclusion: In this population-based study, no association was found between the consumption of different dairy products and the prevalence or incidence of hypertension., Competing Interests: Declaration of competing interest The authors report no conflict of interest., (Copyright © 2024 The Author(s).

Multiple kinetic impact projectiles (KIPs) are responsible for most eye injuries by crowd-control weapons. This review aims to outline an underreported, ongoing series of eye injuries by rubber scattershot in Switzerland, and to relate current knowledge about thresholds for lasting visual loss to the energy limits set on KIPs in crowd control, by way of a retrospective compilation of cases from publicly available records and a review of the pertinent literature. Scattershot can cause irreversible visual loss. Since 1980, there have been 36 known cases of eye injuries by rubber pellets in Switzerland. In 2023, the incidence was higher here than at the peak of protests in France. KIPs were originally cleared for use in crowd control at kinetic and area-normalised energies assumed to lie below the threshold for ocular penetration. However, closed globe injuries suffice to cause permanent visual loss. Lower energy thresholds for lasting damage have been confirmed by the newer literature on paintballs, airbags, air guns and toys. These values may differ in vivo versus in vitro, and in humans versus in animals. There is no clear consensus on how best to predict loss of vision. Underreporting the risks of crowd-control weapons may contribute to their prolonged and increasingly liberal use. Regulations should consider what is known on energy thresholds for permanent visual loss. It is critical for ophthalmologists to be involved in the evaluation and monitoring of eye injuries caused by projectiles, including KIPs and toys. An interdisciplinary approach could help to elucidate damage thresholds., (© 2024. The Author(s).)

Purpose: Children with congenital heart disease (CHD) from low- to middle-income countries (LMIC) are suspected to have a high prevalence of antibiotic-resistant microorganisms (ARMOs) carriage, but data are currently lacking. Carriage of ARMOs could impact the post-operative course in pediatric intensive care unit (PICU). The aim of the study was to assess the prevalence of ARMOs carriage in children with CHD from LMIC and its impact on post-operative outcomes., Methods: This was a retrospective monocentric study from 01/2019 to 12/2022. Included patients were children (0-18 years) from a LMIC admitted after CHD surgery and with AMRO screening performed the week before. Infections and post-operative evolution were compared based on ARMOs carriage status., Findings: Among 224 surgeries (median age 38.5 months (IQR 22-85.5)), ARMOs carriage was evidenced in 95 cases (42.4%). Main organisms isolated were Extended Spectrum Beta-Lactamase (ESBL) producing E. coli (75/224) 33.5%)) and ESBL-K. pneumoniae (30/224) 13.4%)). Median mechanical ventilation duration was 1 day (IQR 0-1), PICU stay 3 days (IQR 2-4) and hospital stay 6.5 days (IQR 5-10). A total of 17 infectious episodes occurred in 15 patients, mostly consisting in hospital-acquired pneumonia (HAP) (12/17). Only two infections were caused by a colonizing ARMO. Occurrence of infections and patients' outcome were similar between ARMO carriers and non-carriers. Higher use of carbapenems (6 (6.3%) vs 1 (0.8%), p = 0.04) and a trend to a higher use of vancomycin (14 (13.7%) vs 9 (6.9%), p = 0.04) in case of ARMOs carriage. Applying current guidelines, negative swab screening could have led to sparing most of empirical vancomycin therapy (11/12) for HAP based on current guidelines., Conclusion: Prevalence of AMROs carriage is high in children from LMIC and has a limited impact on patients' outcome. However, ARMOs carriage leads to higher consumption of antibiotics. Screening may help saving use of broad-spectrum antibiotic in non-carrier patients., (© 2024. The Author(s).)

This report describes the characterization of Burkholderia cenocepacia isolates belonging to sequence type (ST)-250, detected in eight patients with cystic fibrosis (CF) in Switzerland. We retrospectively analyzed 18 isolates of B. cenocepacia ST-250 isolated between 2003 and 2015 by whole-genome sequencing and evaluated clinical and epidemiological data. Single nucleotide polymorphism analysis of the B.°cenocepacia ST-250 lineage showed that the isolates from all patients cluster tightly, suggesting that this cluster has a recent common ancestor. Epidemiological investigations showed that six out of eight patients acquired B.°cenocepacia ST-250 in the years 2001-2006, where participation in CF summer camps was common. Two patients were siblings. Genomic relatedness of the B. cenocepacia ST-250 isolates supported transmission by close contact, however, a common source or nosocomial routes cannot be excluded. With respect to the fatal outcome in six patients, our study shows the importance of infection control measurements in CF patients with B.°cenocepacia., 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 © 2024.

Background: In winter 2022/2023, a resurgence of invasive group A streptococcal (iGAS) infections in children was observed in Europe, including Germany and Switzerland. While a simultaneous increase in consultations for scarlet fever and pharyngitis was reported in England, leading to the recommendation to treat any suspected GAS disease with antibiotics, guidelines in Germany and Switzerland remained unchanged. We aimed to investigate whether this policy was appropriate., Methods: We conducted a retrospective multicenter study of children hospitalized for invasive GAS disease between September 2022 and March 2023 in pediatric departments in Dresden and Berlin (Germany) and Basel (Switzerland). We reviewed medical records and conducted structured telephone interviews to analyze whether suspected GAS infections with or without antibiotic treatment were reported prehospitalization., Results: In total, 63 patients met the inclusion criteria (median age 4.2 years, 57% males); however, clinical information was not complete for all analyzed characteristics; 32/54 (59%) had ≥1 physician visit ≤4 weeks prehospitalization. In 4/32 (13%) patients, GAS disease, that is, tonsillitis or scarlet fever, was suspected; 2/4 of them received antibiotics, and a positive rapid antigen test for GAS was documented in 1 of them., Conclusions: A small minority of patients had suspected GAS infection within 4 weeks before iGAS disease. These data suggest that there is little opportunity to prevent iGAS disease by antibiotic therapy, because in most patients-even if seen by a physician-there was either no evidence of GAS disease or when GAS disease was suspected and treated with antibiotics, consecutive invasive GAS disease was not prevented., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2024 The Author(s).
