    This study investigated instances of the term systems thinking among the websites of the Top 25 business schools as ranked by U. S. News and World Report in 2010. Since a greater number of instances of the term and its variants in a universitys web documents may indicate an increased interest of the institution in the concept of systems thinking, the universities in this study were rated according to their decreasing instances, counts, or website hits. Results indicated that while many schools had little to no mention of the term in any form, some schools used it prolifically on their websites, even when searching and hit counting was adjusted to remove duplicates and isolate inaccurate results. Nevertheless, appearance and discussion of the term was limited in official university information displayed by most schools. The authors assert that an increasing importance should be placed on teaching systems thinking at the graduate level and on providing evidence of this work to prospective business students and their prospective employers through university and business school websites

    Importance The diagnosis of Mycoplasma pneumoniae infection as the cause of mucocutaneous disease is challenging because current diagnostic tests are not able to differentiate M pneumoniae infection from carriage. Objective To examine the frequency and clinical presentation of M pneumoniae-induced mucocutaneous disease in children with community-acquired pneumonia (CAP) using improved diagnostics. Design, Setting, and Participants This prospective, longitudinal cohort study included 152 children aged 3 to 18 years with CAP enrolled in a CAP study from May 1, 2016, to April 30, 2017, at the University Children's Hospital Zurich. Children were inpatients or outpatients with clinically defined CAP according to the British Thoracic Society guidelines. Data analysis was performed from July 10, 2017, to June 29, 2018. Main Outcomes and Measures Frequency and clinical presentation of M pneumoniae-induced mucocutaneous disease in childhood CAP. Mycoplasma pneumoniae infection was diagnosed by polymerase chain reaction (PCR) of oropharyngeal samples and confirmed with the measurement of specific peripheral blood IgM antibody-secreting cells by enzyme-linked immunospot assay to differentiate M pneumoniae-infected patients from carriers with CAP caused by other pathogens. Mucocutaneous disease was defined as any eruptive lesion that involved skin and/or mucous membranes occurring during the CAP episode. Results Among 152 enrolled children with CAP (median [interquartile range] age, 5.7 [4.3-8.9] years; 84 [55.3%] male), 44 (28.9%) tested positive for M pneumoniae by PCR; of these, 10 children (22.7%) developed mucocutaneous lesions. All 10 patients with mucocutaneous eruptions tested positive for specific IgM antibody-secreting cells. Skin manifestations were found in 3 cases (2.8%) of M pneumoniae PCR-negative CAP (P < .001). The spectrum of M pneumoniae-induced mucocutaneous disease included M pneumoniae-induced rash and mucositis (3 cases [6.8%]), urticaria (2 cases [4.5%]), and maculopapular skin eruptions (5 cases [11.4%]). Two patients had ocular involvement as the sole mucosal manifestation (bilateral anterior uveitis and nonpurulent conjunctivitis). Patients with M pneumoniae-induced mucocutaneous disease had longer duration of prodromal fever (median [interquartile range], 10.5 [8.3-11.8] vs 7.0 [5.5-9.5] days; P = .02) and higher C-reactive protein levels (median [interquartile range], 31 [22-59] vs 16 [7-23] mg/L; P = .04) than patients with CAP due to M pneumoniae without mucocutaneous manifestations. They were also more likely to require oxygen (5 [50%] vs 1 [5%]; P = .007), to require hospitalization (7 [70%] vs 4 [19%]; P = .01), and to develop long-term sequelae (3 [30%] vs 0; P = .03). Conclusions and Relevance Mucocutaneous disease occurred significantly more frequently in children with CAP due to M pneumoniae than in children with CAP of other origins. Mycoplasma pneumoniae-induced mucocutaneous disease was associated with increased systemic inflammation, morbidity, and a higher risk of long-term sequelae

    Background Binge drinking is a widespread health compromising behavior among adolescents and young adults, leading to significant health problems, injuries and mortality. However, data on alcohol consumption is often unreliable, as it is mainly based on self-reporting surveys. In this five-year study (2014–2019) at the University Children’s Hospital Zurich, we analyzed blood samples from adolescent binge drinking patients to investigate blood alcohol concentrations (BACs), co-ingestion of drugs, assess compliance between self-reported and measured substance use, and test for genetic components of innate alcohol tolerance. Furthermore, hair analysis was performed to retrospectively access drug exposure and to evaluate the potential of hair analysis to assess binge drinking. Methods In a prospective, single-center study, patients with alcohol intoxications aged 16 years and younger were included. Blood and hair samples were analyzed by sensitive liquid chromatography – tandem mass spectrometry drug analysis. HTTLPR genotyping was performed with PCR and fragment analysis. Results Among 72 cases, 72 blood and 13 hair samples were analyzed. BACs ranged from 0.08–3.20‰ (mean 1.63‰, median 1.60‰), while a mean concentration of 3.64 pg/mg hair (median 3.0 pg/mg) of the alcohol marker ethyl glucuronide (EtG) was detected in eleven hair samples, providing no evidence of chronic excessive drinking. In 47% of the cases, co-ingested drugs were qualitatively detected next to ethanol, but only 9% of the detected drugs had blood concentrations classified as pharmacologically active. Cannabis consumption (22%) and stimulant intake (16%) were the most frequently observed drugs. Compliance between patients’ statements and measured substances matched well. Although we investigated the genetic contribution to innate alcohol tolerance via the 5-HTTLPR polymorphism, the diverse genetic background of the cohort and small sample size did not allow any conclusions to be drawn. Conclusion Almost half of our binge drinking patients tested positive for other substances, primarily cannabis. We anticipate that our study enhances understanding of consumption behavior of young people and encourage continued efforts to address the harmful effects of binge drinking and co-occurring substance use

    AIMS OF THE STUDY The COVID-19 pandemic is likely to overlap with the seasonal influenza epidemic, increasing the risk of overextending the health system capacity in Switzerland. Influenza vaccine uptake has remained low in most countries, including Switzerland. The aim of the study was to determine parents' intentions towards influenza vaccination of their children as well as themselves, and to assess regional differences. METHODS Parents presenting to four pediatric emergency departments (PEDs; Zurich, Bern, Bellinzona, Geneva) were asked to complete an online survey during and after the first lockdown of the COVID-19 pandemic (April - June 2020). The anonymized survey included demographic information, vaccination history and intentions to vaccinate against influenza, as well as attitudes towards future vaccination against COVID-19. RESULTS The majority of children (92%; 602/654) were up-to-date on their vaccination schedule. In 2019/2020, 7.2% (47/654) were vaccinated against influenza. Children with chronic illnesses were more frequently vaccinated compared to healthy children (19.2% vs 5.6%; p = 0.002). For the coming winter season, 111 (17%) parents stated they plan to vaccinate their children against influenza, more than double the rate from last year, and 383 (59.2%) parents suggest they will vaccinate against COVID-19 once a vaccine is available. Regional differences between "German" and "Latin" Switzerland were found for parents' intent to have their children vaccinated against influenza next season (Zurich and Bern 14.3%, Bellinzona and Geneva 27.2%, p &lt; 0.001) but not for a hypothetical vaccination against COVID-19 (Zurich and Bern 59.1%, Bellinzona and Geneva 59.7%, p = 0.894). CONCLUSIONS The COVID-19 pandemic resulted in a substantial increase of parents' intention to vaccinating their children against influenza, especially in hard-hit "Latin" Switzerland. The Swiss government and public health organizations can leverage these regional results to promote influenza vaccination among children for the coming seasons

    Tongue lacerations in children: to suture or not?

    Full text link
    AIMS OF THE STUDY Tongue lacerations are common in children, occurring mostly from falls or sports injuries. Optimal treatment of tongue lacerations is a challenge for paediatricians due to contradictory recommendations and a lack of current guidelines. It remains unclear which tongue lacerations should be sutured and which would benefit from spontaneous healing, which is a promising alternative. In recent years, the treatment of choice in our paediatric emergency department (ED) has shifted from generally suturing the wounds to more frequently advising secondary wound healing. The aim of this study was to analyse tongue lacerations treated at our ED in order to develop guidance for the optimal management of tongue lacerations in children. METHODS This retrospective study was conducted to assess tongue lacerations at the ED of a University Children's Hospital Zurich from January 2010 to August 2015. All families were contacted for informed consent and photo documentation of the healed tongue. Clinical records of all the patients included were reviewed and different variables were defined and analysed. RESULTS A total of 73 children with tongue lacerations were included (75.3% boys, mean age ± standard deviation 4.0 ± 2.6 years). The mean size of the lacerations was 12.4 ± 8.3 mm, with affected tongue borders in 51 cases (69.9%) and a through-and-through laceration in 23 patients (31.5%). A primary wound closure was performed in 12 children (16.4%). These wounds were significantly larger than those of the secondary wound healing group (21 ± 10 mm compared to 10.8 ± 6.8 mm), presented gaping wound edges with the tongue at rest more frequently (91.7% compared to 32.8%), and showed through-and-through lacerations more often (91.7% compared to 19.7%). The group with wound suturing needed longer to recover (median 13 days compared to 6.2 days) and had a higher rate of complications (25 vs 3.3%). CONCLUSIONS Suturing is not required in gaping tongue lacerations less than 2 cm long that do not involve the tip of the tongue. The Zurich Tongue Scheme was developed as a guide for clinicians when deciding which tongue lacerations need suturing

    Metabolomics analysis of antiquitin deficiency in cultured human cells and plasma: Relevance to pyridoxine-dependent epilepsy

    Full text link
    Deficiency of antiquitin (α-aminoadipic semialdehyde dehydrogenase), an enzyme involved in lysine degradation and encoded by ALDH7A1, is the major cause of vitamin B6-dependent epilepsy (PDE-ALDH7A1). Despite seizure control with high dose pyridoxine (PN), developmental delay still occurs in approximately 70% of patients. We aimed to investigate metabolic perturbations due to possible previously unidentified roles of antiquitin, which may contribute to developmental delay, as well as metabolic effects of high dose pyridoxine supplementation reflecting the high doses used for seizure control in patients with PDE-ALDH7A1. Untargeted metabolomics by high resolution mass spectrometry (HRMS) was used to analyze plasma of patients with PDE-ALDH7A1 and two independently generated lines of cultured ReNcell CX human neuronal progenitor cells (NPCs) with CRISPR/Cas mediated antiquitin deficiency. Accumulation of lysine pathway metabolites in antiquitin-deficient NPCs and western-blot analysis confirmed knockdown of ALDH7A1. Metabolomics analysis of antiquitin-deficient NPCs in conditions of lysine restriction and PN supplementation identified changes in metabolites related to the transmethylation and transsulfuration pathways and osmolytes, indicating a possible unrecognized role of antiquitin outside the lysine degradation pathway. Analysis of plasma samples of PN treated patients with PDE-ALDH7A1 and antiquitin-deficient NPCs cultured in conditions comparable to the patient plasma samples demonstrated perturbation of metabolites of the gamma-glutamyl cycle, suggesting potential oxidative stress-related effects in PN-treated patients with PDE-ALDH7A1. We postulate that a model of human NPCs with CRISPR/Cas mediated antiquitin deficiency is well suited to characterize previously unreported roles of antiquitin, relevant to this most prevalent form of pyridoxine-dependent epilepsy

    Factors associated with unvaccinated caregivers who plan to vaccinate their children

    Full text link
    Vaccine hesitancy is complex and a threat to global public health during the ongoing COVID-19 pandemic. Our objective was to determine factors associated with caregivers' willingness to vaccinate children despite not being immunized themselves against COVID-19. The International COVID-19 Parental Attitude Study (COVIPAS), a multinational cohort study, recruited caregivers of children 0-18 years old in 21 Emergency Departments (EDs) in USA, Canada, Israel, and Switzerland during November-December 2021. Of a total of 4536 caregivers who completed the survey, 882 (19.4%) were unvaccinated, and 62 (7.0%) of the unvaccinated planned to vaccinate their children. Unvaccinated caregivers with children that had their childhood vaccines up-to-date (OR 3.03 (1.36, 8.09), p = 0.01), and those very worried their child has COVID-19 in the ED (OR 3.11 (1.44, 6.34), p < 0.01) were much more likely to plan to immunize their children. Primary care providers and public health agencies should not assume that unvaccinated parents will not vaccinate their children. Determining child's vaccination status and parental level of concern about COVID-19 may help identify caregivers who are open to give their children the vaccine.

    OBJECTIVES Fractures of carpal bones other than the scaphoid are rare in children. The aim of this study was to analyze results and identify risk factors for an unfavorable outcome. MATERIAL AND METHODS Children and adolescents up to the age of 16 years who sustained a carpal fracture other than in the scaphoid between 2004 and 2021 were reviewed in this single-center retrospective study. RESULTS In a series of 209 children and adolescents with carpal fractures, 22 had fractures other than the scaphoid. Mean age was 13 years (range 8-16) years, with a total of 41 fractures, with highest incidences for the capitate (10), trapezium (6), triquetrum (4) and pisiform (4). Twenty-nine of these 41 fractures were missed on initial X-ray. Non-displaced fractures were treated with a short arm spica cast including the thumb. Four patients were operated on for displacement fracture or carpometacarpal subluxation. All fractures united, and patients returned to full activities. At the final consultation at a median 14 months (range 6-89) post-injury, all patients with non-displaced fractures were free of symptoms, with excellent Mayo Wrist Scores (MWS). However, three patients with operated trapezium fractures developed early radiological signs of osteoarthritis, two of them with residual pain and MWS rated only good. CONCLUSION Non-displaced pediatric carpal fractures treated by forearm cast have excellent prognosis. Fractures of the trapezium with displacement or first carpometacarpal subluxation incur a risk of osteoarthritis despite anatomical reduction and internal fixation

    Detection of mostly viral pathogens and high proportion of antibiotic treatment initiation in hospitalised children with community-acquired pneumonia in Switzerland – baseline findings from the first two years of the KIDS-STEP trial

    Full text link
    AIMS OF THE STUDY: Globally, since the introduction of conjugate-vaccines against encapsulated bacteria, respiratory viruses have caused most hospitalisations for community-acquired pneumonia. The aim of this study was to describe pathogens detected and their association with clinical findings in Switzerland. METHODS: Baseline data were analysed for all trial participants enrolled between September 2018 and September 2020 into the KIDS-STEP Trial, a randomised controlled superiority trial on the effect of betamethasone on clinical stabilisation of children admitted with community-acquired pneumonia. Data included clinical presentation, antibiotic use and results of pathogen detection. In addition to routine sampling, nasopharyngeal specimens were analysed for respiratory pathogens using a panel polymerase chain reaction test covering 18 viral and 4 bacterial pathogens. RESULTS: 138 children with a median age of 3 years were enrolled at the eight trial sites. Fever (obligatory for enrolment) had been present for median 5 days before admission. Most common symptoms were reduced activity (129, 93.5%) and reduced oral intake (108, 78.3%). Oxygen saturation <92% was found in 43 (31.2%). Forty-three participants (29.0%) were already on antibiotic treatment prior to admission and 104 participants (75.4%) received antibiotic treatment on admission. Pathogen testing results were available from 132 children: 31 (23.5%) had respiratory syncytial virus detected, 21 (15.9%) human metapneumovirus. The pathogens detected showed expected seasonal and age preponderance and were not associated with chest X-ray findings. CONCLUSIONS: In the context of the predominantly viral pathogens detected, the majority of antibiotic treatment is probably unnecessary. The ongoing trial, as well as other studies, will be able to provide comparative pathogen detection data to compare pre- and post-COVID-19-pandemic settings

    Caregiver-reported delay in presentation to pediatric emergency departments for fear of contracting COVID-19: a multi-national cross-sectional study

    Full text link
    Objective: To determine if caregivers of children presenting to pediatric emergency departments (EDs) during the COVID-19 pandemic are delaying presenting to care for fear of contracting COVID-19. Methods: This was a pre-planned secondary analysis of a cross-sectional survey study of caregivers accompanying their children aged 0-19 years to 16 pediatric EDs in 5 countries from May to June 2020. An anonymous online survey, completed by caregivers via RedCAP, included caregiver and child demographics, presenting complaints, if they delayed presentation and whether symptoms worsened during this interval, as well as caregiver concern about the child or caregiver having COVID-19 at the time of ED visit. Results: Of 1543 caregivers completing the survey, 287 (18.6%) reported a delay in seeking ED care due to concerns of contracting COVID-19 in the hospital. Of those, 124 (43.2%) stated their child's symptoms worsened during the waiting interval. Caregiver relationship to child [mother] (OR 1.85, 95% CI 1.27-2.76), presence of chronic illness in child (OR 1.78. 95% CI 1.14-2.79), younger age of caregiver (OR 0.965, 95% CI 0.943-0.986), and caregiver concerns about lost work during the pandemic (OR 1.08, 95% CI 1.04-1.12) were independently associated with a COVID-19-related delayed presentation in multivariable regression analysis. Conclusions: Almost one in five caregivers reported delaying ED presentation for their ill or injured child specifically due to fear of contracting COVID-19 while in hospital, with mothers, younger caregivers, caregivers of children with chronic illness, and those concerned about lost work more likely to report delaying ED presentation.
