The term lymphadenopathy refers to an abnormality in size, consistency or morphological aspect of one or several lymph nodes. Although lymphadenopathies are commonly observed in everyday clinical practice, the difficulty of differentiating benign and malignant disease may delay therapeutic approaches. The present review aims to update diagnostic algorithms in different clinical situations based on the currently available literature.
A literature review was performed to assess current knowledge of and to update the diagnostic approach. A short clinical vignette was used as an example of a typical clinical presentation. This case of metastatic lymphadenopathy with incomplete patient history demonstrates how misleading such lymphadenopathy may be, leading to a delayed diagnosis and even a fatal outcome.
Any lymphadenopathy persisting for more than 2 weeks should be considered suspicious and deserves further investigation. Precise clinical examination, meticulous history-taking and a search for associated symptomatology are still cornerstones for diagnosing the origin of the condition. The next diagnostic step depends on the anatomical region and the specific patient’s situation. Imaging starts with ultrasound, while computed tomography (CT) and magnetic resonance imaging (MRI) allow assessment of the surrounding structures. If the diagnosis remains uncertain, tissue sampling and histological analyses should be performed.
Except for head and neck loco-regional lymphadenopathy, there are no methodical guidelines for persistent lymphadenopathy. The present review clarifies several confusing and complex situations. The accuracy of fine needle aspiration cytology could be increased by using core needle biopsy with immunocytologic and flow cytometric methods. Notably, except in the head and neck area, open biopsy remains the best option when lymphoma is suspected or when inconclusive results of previous fine needle aspiration cytology or core needle biopsy are obtained. The incidence of malignant lymphadenopathy varies with its location and the various diagnostic strategies. In metastatic lymphadenopathy of unknown primary origin, European Society for Medical Oncology (ESMO) guidelines and modern methods like next-generation sequencing (NGS) may help to manage such complex cases.
Temporary, sudden, shooting and recurrent unilateral facial pain in the supply area of one or more trigeminal nerve branches characterises trigeminal neuralgia. Innocuous stimuli trigger the pain, e.g. chewing, speaking or brushing teeth. In some patients, paroxysms superimpose on continuous pain. In aetiological terms, idiopathic, classic (due to neurovascular compression) and secondary trigeminal neuralgia (e.g. due to multiple sclerosis, brainstem ischaemia and space-occupying lesions) are defined. Many drugs may be efficacious, with carbamazepine being first-choice therapy. However, non-pharmacological and invasive procedures may also help. To reach the correct diagnosis and determine the best therapeutic measures, adequate pain characterisation and interdisciplinary collaboration are essential. We hereby present our experience of an interdisciplinary approach for the diagnosis and treatment of trigeminal neuralgia.
AIM: This study aims to evaluate the prognostic role of the KRAS G12C mutation in patients with advanced non-small cell lung cancer and PD-L1 expression ≥50% who are treated with immune checkpoint inhibitor monotherapy.
METHODS: We conducted a systematic review of clinical studies fulfilling the following criteria: (1) enrolling patients with advanced/metastatic non-small cell lung cancer with high PD-L1 tumour expression receiving first-line therapy with anti-PD-(L)1 immune checkpoint inhibitors; (2) comparing the outcomes of patients with the KRAS G12C mutation to those without this mutation, and (3) reporting overall survival and progression-free survival (PFS). The electronic databases Medline, EMBASE, Cochrane and Google Scholar, along with reference lists, were systematically searched.
RESULTS: We identified four publications that fulfilled the inclusion criteria, comprising a total of 469 patients. Of these, two studies reported hazard ratios (HR) for PFS, resulting in a final pooled patient sample of 163 for the meta-analysis. In patients with non-small cell lung cancer who received anti-PD-(L)1 monotherapy, the presence of a KRAS G12C mutation was associated with improved PFS compared to patients with KRAS wild-type tumours, with a pooled hazard ratio of 0.39 and a 95% Confidence Interval (CI) of 0.25–0.63. Among all patients with KRAS mutations, those harbouring a KRAS G12C mutation had improved PFS compared to patients with any other KRAS mutation (pooled HR 0.33, 95% CI 0.19–0.57).
CONCLUSIONS: Patients with non-small cell lung cancer who have the KRAS G12C mutation and high PD-L1 expression demonstrate favourable PFS with first-line PD-(L)1 immune checkpoint inhibitor monotherapy compared to patients with KRASwt or other KRAS mutations and high PD-L1 expression.
AIMS OF THE STUDY: Anti-reflux surgery aims to restore the anti-reflux barrier and reduce the retrograde flow of stomach contents. However, traditional surgical techniques generally involve some degree of encircling of the oesophagus, which can result in adverse effects such as dysphagia and the inability to belch or vomit. Based on the first published results, a novel surgical technique – with the RefluxStop™ device – appears promising for treating gastroesophageal reflux disease (GERD) with minimal postoperative dysphagia. This study describes the initial clinical experience with this procedure in a cohort of patients with chronic gastroesophageal reflux disease to evaluate its feasibility and safety in clinical practice.
METHODS: This retrospective cohort study examined the first 40 patients who underwent laparoscopic anti-reflux surgery with the RefluxStop™ device at a private hospital in Switzerland. The procedure involves implanting a nonactive device on the outside of the gastric fundus to stabilise a narrow oesophagogastric plication. Feasibility was assessed based on the proportion of patients in whom the device could be successfully implanted, with a discussion of the operative details. Intraoperative and postoperative complications, adverse effects, and changes in gastroesophageal reflux disease-related quality of life (GERD-HRQL questionnaire) are also reported.
RESULTS: Between May 2020 and April 2022, 40 patients underwent elective surgery for laparoscopic hiatal hernia repair and RefluxStop™ device implantation. All patients had typical symptoms of gastroesophageal reflux disease, such as heartburn and regurgitation; 20 (50%) had preoperative dysphagia. Laparoscopic surgery was feasible in all patients except one who required laparotomy due to adhesions and associated bleeding when accessing the abdomen. The median operating time was 57.5 minutes (interquartile range = 51.75–64.25 minutes) with no device-related intraoperative or postoperative complications. All patients were imaged one day and three months postoperative, confirming the correct placement of the device. Reflux symptoms (heartburn and acid regurgitation) were significantly improved in all patients at three months (p <0.0001).
CONCLUSION: These preliminary results support the feasibility and safety of introducing this novel laparoscopic anti-reflux surgical treatment option in clinical practice.
INTRODUCTION: There is limited understanding of the pathomechanistic relationship between leptomeningeal collateral formation and ischaemic stroke aetiology. We aimed to assess the association of leptomeningeal collateral status and ischaemic stroke aetiology, using the widely recognised “Trial of Org 10172 in Acute Stroke Treatment” (TOAST) classification categorising strokes into five distinct aetiologies.
METHODS: Retrospective study of consecutively admitted adult ischaemic stroke patients at a Swiss stroke centre. Leptomeningeal collateral status was assessed on admission with single-phase CT-angiographies using a validated 4-point score. Patients were categorised into large-artery atherosclerosis (LAA), cardioembolic (CE), small-vessel disease (SVD) and cryptogenic (CG) according to the TOAST classification. We performed ordinal and binary (poor [collaterals filling ≤50% of the occluded territory] vs good [collaterals filling >50% of the occluded territory] collateralisation) logistic regression to evaluate the impact of TOAST aetiology on collateral status.
RESULTS: Among 191 patients, LAA patients had better collateral status compared to non-LAA aetiology (LAA: 2 vs CE: 2 vs SVD: 3 vs CG: 2, pLAA vs non-LAA = 0.04). In weighted multivariate logistic regression, LAA and SVD independently predicted better collateral status (binary models [adjusted odds ratio; aOR]: LAA: 3.72 [1.21–11.44] and SVD: 4.19 [1.21–14.52]; ordinal models [adjusted common odds ratio; acOR]: LAA: 2.26 [95% CI: 1.23–4.15] and SVD: 1.94 [1.03–3.66]), while CE predicted worse collateral status (binary models [aOR]: CE: 0.17 [0.07–0.41]; ordinal models [acOR]: CE: 0.24 [0.11–0.51]).
CONCLUSION: The aetiology of ischaemic stroke is associated with leptomeningeal collateral status on single-phase CT-angiography, with LAA and SVD predicting better and CE predicting worse collateral status.
AIM OF THE STUDY: The purpose of the present study was to evaluate demographic characteristics of inmates in the Canton of Zurich (exposure), and investigate the changes in diseases and drug use between 2015 and 2020 (outcome).
METHODS: The study prospectively evaluated 51,989 inmates admitted to the Police Prison Zurich in Switzerland between 1 April 2015 and 31 August 2020 and who were systematically medically assessed. A total of 19,027 (37%) inmates had one or more health conditions, which the authors recorded according to the International Classification of Diseases-10 (ICD-10), in addition to demographic data (country of origin, sex, age, year of imprisonment), as well as details of any drugs used (type and dosage).
RESULTS: The 19,027 inmates with medical conditions had a mean age of 35.4±12.5 years (range 10–89) and comprised 16,489 males (87%). The inmates originated from 170 countries, including 4606 from Switzerland (24.2%), 4227 from Eastern Europe (22%) and 3432 from the Middle East & North Africa (18%). A total of 1631 inmates (9%) were enrolled in the medication-assisted treatment (MAT) programme, and 672 patients (4%) received a psychiatric evaluation. The proportions of foreign prisoners did not increase during the study period. There was a significant increase in the use of antipsychotics from year 1 to 5 (y = 0.866x; R2 = 0.902; p = 0.01) and anticonvulsants from year 1 to 4 (y = 1.27x; R2 = 0.823; p = 0.01), and a significant decrease in the use of analgesics from year 2 to 5 (y = -4.42x; R2 = 0.947; p = 0.03) and antianxiety drugs from year 1 to 4 (y = -3.31x; R2 = 0.989; p = 0.005). Inmates from Switzerland were most likely to use antianxiety drugs, while inmates from the Middle East & North Africa were most likely to use antipsychotics (OR 2.09; CI 1.88–2.34) and anticonvulsants (OR 3.52; CI 2.90–4.29), whereas inmates from Latin and North America were most likely to use herbal medicine (OR 1.50; CI 1.05–2.10).
CONCLUSIONS: The findings of this study could help anticipate needs of prisons as well as improve treatment of disease and assist with substance use or abuse, particularly in the context of migration.
OBJECTIVES: Colorectal carcinoma remains one of the most common malignancies worldwide. Colonoscopy screening is most effective for early detection and tumour prevention and is currently recommended in Europe for adults aged over 50 years. However, given that an increasing proportion of patients are diagnosed before the age of 50, we set out to determine the detection rate of colorectal carcinoma in patients younger than 50 years and to determine the best threshold for starting colonoscopy screening.
METHODS: Single-centre, retrospective cohort study of all colonoscopies performed, regardless of indication, in our department at a tertiary Swiss university hospital in patients aged ≥18 and <60 years between 2016 and 2021. Colorectal cancer detection rate was calculated per 5-year age group and analysed separately by sex.
RESULTS: The current analysis included 2846 colonoscopies performed for any indication. Colorectal carcinoma was found in 5/366 (1.4%) patients aged 45–49 years (3/210 or 1.4% of males and 2/156 or 1.3% of females) and in 9/819 (1.1%) patients aged 50–54 years (5/495 or 1.0% of males and 4/324 or 1.2% of females). Adenomas with high-grade dysplasia were found in 5/366 (1.4%) patients aged 45–49 years and in 11/819 (1.3%) aged 50–54 years; by sex, in 4/210 or 1.9% of males and 1/156 or 0.6% of females aged 45–49 years, and in 6/495 or 1.2% of males and 5/324 or 1.5% of females aged 50–54 years. Detection of adenoma with low-grade dysplasia increased from 14.6% (21/144) at age <30 years to 41% (150/366) at 45–49 years and 43.5% (356/819) at 50–54 years. A similar increasing trend was also seen if we analysed these groups by sex.
CONCLUSIONS: The detection rate of colorectal carcinoma, but also adenomas, in our patients aged 45–49 years was similar to that in patients aged over 50, in both sexes. Thus our data are in line with the assumption that lowering the screening age to 45 years might be reasonable from a medical point of view for achieving a reduction in disease-specific mortality by improved screening strategies.
BACKGROUND: Respiratory distress syndrome is a leading cause of neonatal intensive care unit admissions for late preterm (34–36 weeks gestational age) and term infants (37–41 weeks). The risk for respiratory morbidity appears to increase after an elective caesarean delivery and might be reduced after antenatal corticosteroids. However, before considering antenatal corticosteroids for women at high risk of preterm birth after 34 weeks, the incidence of respiratory distress syndrome and the effect of delivery mode on this incidence requires further evaluation. Therefore, this study aimed to investigate the relationship between respiratory distress syndrome incidence and delivery mode in late preterm and term infants.
METHODS: In this retrospective cohort study, the clinical databases of the University Hospitals of Zurich and Basel were queried regarding all live births between 34 + 0 and 41 + 6 weeks. Neonatal intensive care unit admissions due to respiratory distress syndrome were determined and analysed in regard to the following delivery modes: spontaneous vaginal, operative vaginal, elective caesarean, secondary caesarean and emergency caesarean.
RESULTS: After excluding malformations (n = 889) and incomplete or inconclusive data (n = 383), 37,110 infants out of 38,382 were evaluated. Of these, 5.34% (n = 1980) were admitted to a neonatal intensive care unit for respiratory distress syndrome. Regardless of gestational age, respiratory distress syndrome in infants after spontaneous vaginal delivery was 2.92%; for operative vaginal delivery, it was 4.02%; after elective caesarean delivery it was 8.98%; following secondary caesarean delivery, it was 8.45%, and after an emergency caesarean it was 13.3%. The risk of respiratory distress syndrome was higher after an elective caesarean compared to spontaneous vaginal delivery, with an odds ratio (OR), adjusted for gestational age, of 2.31 (95% CI 1.49–3.56) at 34 weeks, OR 5.61 (95% CI 3.39–9.3) at 35 weeks, OR 1.5 (95% CI 0.95–2.38) at 36 weeks, OR 3.28 (95% CI 1.95–5.54) at 37 weeks and OR 2.51 (95% CI 1.65–3.81) at 38 weeks. At 39 weeks, there was no significant difference between the risk of respiratory distress syndrome after an elective caesarean vs. spontaneous vaginal delivery. Over the study period, gestational age at elective caesarean delivery remained stable at 39.3 ± 1.65 weeks.
CONCLUSION: The incidence of respiratory distress syndrome following an elective caesarean is up to threefold higher in infants born with less than 39 weeks gestational age compared to those born by spontaneous vaginal delivery. Therefore — and whenever possible — an elective caesarean delivery should be planned after 38 completed weeks to minimise the risk of respiratory morbidity in neonates.
AIMS: Bariatric surgery induces several micronutrient deficiencies that require supplementation. For iron, parenteral infusions are usually preferred over oral supplementation. Ferric carboxymaltose infusion has been associated with hypophosphataemia, mostly transient and asymptomatic. However, in some cases, ferric carboxymaltose-induced hypophosphataemia may persist for weeks to months and may induce muscle weakness, osteomalacia and bone fractures. The aim of this study was to identify possible predictors of a clinically relevant decrease in serum phosphate after ferric carboxymaltose infusion in patients with previous Roux-en-Y gastric bypass.
METHODS: Patients with previous Roux-en-Y gastric bypass who received ferric carboxymaltose infusions between January 2018 and September 2019 and had recorded phosphataemia before and after ferric carboxymaltose infusion at the Lausanne University Hospital, Lausanne, Switzerland, were studied retrospectively. A multiple linear regression model was built with delta phosphataemia as the outcome to investigate the factors related to magnitude of serum phosphate lowering.
RESULTS: Seventy-seven patients (70 females and 7 males) with previous Roux-en-Y gastric bypass were studied. Mean age (SD) was 43.2 (10.7) years and median BMI was 30.9 kg/m2 (IQR 27.9–36.4). Sixty-eight patients (88.3%) received an infusion of 500 mg ferric carboxymaltose and 9 patients (11.7%) received 250 mg ferric carboxymaltose. Forty-nine patients (63.6%) developed hypophosphataemia (<0.8 mmol/l) after ferric carboxymaltose infusion. Median plasma phosphate significantly decreased by 0.33 mmol/l (IQR 0.14–0.49) (p<0.0001). Multiple linear regression identified the ferric carboxymaltose dose as the only risk factor significantly associated with the magnitude of serum phosphate lowering, with an additional mean loss of 0.26 mmol/l with a 500 mg infusion compared to a 250 mg infusion (p = 0.020).
CONCLUSION: Ferric carboxymaltose infusions substantially decreased plasma phosphate levels in patients with previous Roux-en-Y gastric bypass. Compared to a dose of 250 mg, infusion of a dose of 500 mg ferric carboxymaltose decreased the plasma phosphate further in this population.
AIMS OF THE STUDY: This research aimed to investigate the self-directed learning (SDL) habits of Swiss general practitioners from the German-speaking part of Switzerland, understanding how they acquire new knowledge, exploring the impact of the COVID-19 pandemic on these habits and identifying optimisation strategies for their future self-directed learning.
METHODS: We employed a qualitative study design, conducting semi-structured interviews with 16 general practitioners from 30 May 2022 to 06 July 2022. Thematic analysis based on a mixed deductive/inductive approach was used to gain insight into the learning activities and self-directed learning practices of the practitioners.
RESULTS: The interviewed general practitioners demonstrated a versatile approach to self-directed learning, where peer communication emerged as the most predominant learning method. It is noteworthy that the younger generation in particular showed a strong inclination for peer learning and is well prepared for the integration of advanced digital solutions for peer communication. Furthermore, a significant shift was observed in media-based self-directed learning, especially since the COVID-19 pandemic. Digital platforms and repositories for practical learning were mentioned as educational mainstays by many interviewees, reflecting a profound technological shift observed over the past 25 years and especially since the pandemic. The primary motivation for pursuing new knowledge remains patient care, although personal development and staying up-to-date with medical and technological advancements are also key motivators. Although the pandemic has undeniably accelerated the transition towards digital learning, it has also brought with it challenges such as information overload and technical difficulties. There was an evident decline in formal learning venues and physical presence during the pandemic, yet the reported value of in-person interactions remains high. Suggestions for optimising self-directed learning included enhancing digital offerings, fostering stronger peer networks and integrating more practical content.
CONCLUSIONS: The COVID-19 pandemic has catalysed a transformation in the self-directed learning practices of general practitioners in the German-speaking part of Switzerland, underlining the importance of a balanced approach between digital and traditional learning methods. As the digital realm of self-directed learning grows, it is essential to address existing challenges and capitalise on potential advantages. Both individual networking efforts like general practitioner quality circles and initiatives from official authorities like informal self-test opportunities can play pivotal roles in refining self-directed learning practices. The findings from this study offer valuable insights for enhancing learning resources and environments that align with general practitioners’ needs and preferences. Future research should investigate the ongoing impact of advanced digital technologies on self-directed learning to understand the evolving landscape in a post-pandemic world.
AIM OF THE STUDY: The aim of this study is to provide an analysis of the career trajectory of the recipients of a Swiss National MD-PhD grant thirty years after the creation of the Swiss interuniversity MD-PhD programme.
METHODS: The study surveyed 277 recipients of a Swiss National MD-PhD grant using an online questionnaire in April 2022. There were twenty questions about participants’ demographics, the duration of their MD-PhD training, their career trajectory, current position, research and clinical activity, the impact of the support on the recipients’ careers, and their satisfaction with various aspects of the grant.
RESULTS: The study showed that 141 out of the 277 grant recipients contacted returned the survey (51% response rate). The gender distribution of the participants was 33% women, 63% men, 4% unknown, which is almost the same as that of all grantees (35% women, 65% men). One hundred and fourteen (81%) respondents had completed their MD-PhD thesis and were graduates, while 27 (19%) were still MD-PhD students. The mean duration of the MD-PhD training was 4.27 years, with a slight upward trend over time. A large proportion of graduates, 81%, remained scientifically active after the grant, most of them in academic settings. Of the grantees who had completed their MD-PhD at least eight years before the survey, 55% had a paid research position with 40% combining research and clinical roles, and 15% doing research only. Seventy-six per cent remained clinically active, 54% occupied leadership positions, and 25% were professors. Most grantees believed that the grant had had a positive impact on their career trajectory. The main challenges included a delay in clinical training, a limited number of clinical positions with dedicated research time after the MD-PhD period, and sub-optimal recognition by hospital hierarchies.
CONCLUSION: The data collected for this study confirm that the competitive Swiss National MD-PhD Grants Programme excels in supporting promising physician scientists who remain active in both research and clinical contexts in the long term. The individual grants are perceived as a distinction that acts as the basis for a successful career in academic medicine. Continued support and alternative funding sources, however, will be essential to ensure the programme’s sustainability.
INTRODUCTION: Quantifying antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and neutralising antibodies may help to understand protection at the individual and population levels. Determination of neutralising antibodies using classical virus neutralisation tests (VNT) is considered the gold standard, but they are costly and time-intensive. Enzyme-linked immunosorbent assay (ELISA)-based surrogate VNTs (sVNT) or anti-SARS-CoV-2 spike protein receptor binding domain immunoglobulins (anti-S-RBD Ig) may be suitable alternatives to VNTs. We aimed to (a) explore the correlations between anti-S-RBD Ig, VNT, and sVNT measurements and (b) describe humoral immunity against SARS-CoV-2 after vaccination, natural infection, and vaccine breakthrough infection in healthy blood donors.
METHODS: We measured total anti-SARS-CoV-2 Ig in 5714 serum samples from 2748 healthy individuals visiting the Swiss Red Cross Blood Donation Centre in Basel from 03/2020 to 04/2022. We used the Elecsys® Anti-SARS-CoV-2 immunoassay (Roche) against the N- and S-receptor binding domain (RBD) proteins. In a subset of 548 samples from 123 donors, we conducted sVNTs against the Wuhan wild-type SARS-CoV-2 (SARS-CoV-2 Neutralizing Antibodies Detection Kit; Adipogen™). In 100 samples from 40 donors, we correlated sVNT and VNTs against the wild-type (D614G WU1) virus. Surveys were sent to the blood donors to collect data on their SARS-CoV-2 infection and vaccination status. Using this data, donors were categorised as “vaccination only”, “infection before vaccination”, “post-vaccine breakthrough infection”, and “natural infection only”.
RESULTS: Our longitudinal observation study cohort consisted of 50.7% males with a median age of 31 years (range 18–75 y). Anti-SARS-CoV-2 N protein positivity rates per month indicate 57.1% (88/154) of the cohort was infected up to 04/2022. No differences in seropositivity were found between sexes, age groups, blood types (AB0 or RhD), and cytomegalovirus serostatus. We observed a high correlation between anti-S-RBD Ig and inhibition percentage (Spearman’s ρ = 0.92, Kendall’s τ = 0.77, p <0.0001). We determined the sensitivity and specificity for the manufacturers’ thresholds for detecting virus-neutralising effects and computed the “best” cut-off based on our real-world data. We categorised 722/1138 (63.5%) donors as vaccination only (82.3%), post-vaccine breakthrough infection (7.8%), infection before vaccination (5.8%), and natural infection only (4.2%). We observed a lower inhibition percentage in the natural infection-only group than in all other vaccinated groups. The infection before vaccination group had higher anti-S-RBD Ig titres after the first vaccine dose than the other vaccinated groups.
CONCLUSION: In total, 57.1% of healthy blood donors were infected with SARS-CoV-2, but natural infection without evidence of vaccination seems to result in substantially lower neutralising antibody levels. An estimate of antibody neutralisation may be helpful to assess reinfection risk. Total anti-S-RBD Ig correlates with surrogate virus neutralisation test results, a surrogate for neutralisation; therefore, we suggest that total anti-S-RBD Ig may estimate the level of neutralising antibodies. The threshold for protection from an unfavourable clinical outcome must be evaluated in prospective clinical cohorts.
OBJECTIVES: Due to the increasing complexity of the healthcare system, effective communication and data exchange between hospitalists (in-hospital physicians) and primary care physicians (PCPs) is both central and challenging. In Switzerland, little is known about hospitalists’ perception of their communication with PCPs. The primary objective was to assess hospitalists’ satisfaction with their communication with PCPs. Secondary objectives addressed all information about the referral process and communication with PCPs during and after the hospital encounter. Lastly, the results of a previous survey among PCPs were juxtaposed to compare their responses to similar questions.
METHODS: This study surveyed hospitalists in six hospitals in the Central Switzerland region. The survey was sent via email to hospitalists from November 2021 to February 2022. The questionnaire contained 17 questions with single- and multiple-choice answers and the option of free-text entry. Exploratory multivariable logistic regression was used to analyse independent associations.
RESULTS: In total, 276 of 1134 hospitalists responded (response rate 24.3%): (1) the majority of hospitalists are satisfied with the general communication (n = 162, 58.7%) as well as with referral letters (n = 145, 52.5%), (2) preferred information channels for referral letters are email (n = 212, 76.8%) and electronic portals (n = 181, 65.5%), (3) the three most important items of information in referrals are: medication list, diagnoses and reason for referral. In multivariable regression, compared to other clinicians, internists independently favoured informing PCPs of emergency admissions of their patients in a timely manner (OR 2.04; 95%CI 1.21–3.49). Comparing responses from PCPs (n = 109), the most prominent discrepancy was that 67% (n = 184) of hospitalists claimed to “always” inform after an encounter, whereas only 7% (n = 8) of PCPs agreed.
CONCLUSION: Most hospitalists are satisfied with the communication with PCPs and prefer electronic communication channels. Room for improvement was found around timely transmission of patient information before and after hospital encounters.
AIM OF THIS STUDY: General internal medicine is a crucial element in healthcare systems. Understanding how many people are and will be working in this field is important to maintain and improve quality for patients in healthcare systems. This can provide a basis for political decisions.
METHODS: We conducted a cross-sectional study to analyse the current and future workforce of generalists (general practitioners and internists in hospitals) in Switzerland. The Swiss Society of General Internal Medicine (SSGIM) distributed a survey to all members. Respondents were asked about their current average workload in 2023 and planned workload in 2033. The responses were used to calculate full-time equivalent (FTE) for the current and future workforce of generalists and to extrapolate FTE for all active SSGIM members. To model the demand by 2033, we derived different scenarios.
RESULTS: Of all 6,232 active SSGIM members, 2,030 (33%) participated: 46% female, 25% (largest age group) 56-65 years old, 19% still in postgraduate training. The average workload in 2023 was 78% for female and 87% for male generalists; the FTE extrapolated to all active SSGIM members in 2023 was 5,246. By 2033, 1,935 FTEs (36%) will retire, 502 FTEs (10%) will reduce their workload, 116 FTEs (2%) will increase their workload and 2,800 FTEs (53%) will remain in the workforce with the same workload as in 2023. To maintain the same workforce as in 2023, 2,321 new FTEs (44%) will be needed by 2033. To fill this gap of 232 FTE new generalists per year, we modelled different scenarios with assumptions of interest, workload, migration and dropouts.
CONCLUSIONS: Within only one decade, 44% of the current workforce of generalists will disappear, mainly due to retirement and decreased workload. To fill this gap, various scenarios need to be incorporated. Politicians are called upon to create the political framework to create attractive training and working conditions for generalists to address the future demand for healthcare services.
INTRODUCTION: Real-world outcomes with the HeartMate 3 left ventricular assist device (LVAD) depending on whether it’s a bridge to transplantation (BTT) or destination therapy (DT) are poorly studied. We aimed to compare the profile and clinical outcomes of patients supported with HeartMate 3 according to a BTT or a DT pre-implantation strategy.
METHODS: All patients consecutively implanted with HeartMate 3 at our centre (University Hospital of Lausanne, Switzerland) in 2015–2022 were analysed in a retrospective observational study. Indications for HeartMate 3 implantation were advanced heart failure despite optimal medical treatment. Patients were treated with a vitamin K antagonist anticoagulant combined with antiplatelet therapy after HeartMate 3 implantation and were followed up monthly at our institution.
RESULTS: Among 71 patients implanted with HeartMate 3 between 2015 and 2022, 51 (71.8%) were implanted as a BTT and 20 (28.2%) as DT. Their median age was 58 (IQR: 52–69) years and 84% of patients were classified as INTERMACS profiles 2–4. The median follow-up duration was 18.3 (IQR: 7.5–33.9) months. Patients in the DT group were older than those in the BTT group (p <0.001) and had more chronic renal failure (p <0.001). They also had a lower 5-year survival rate (mean ± standard error: 87.3 ± 5.6% vs 49.4 ± 15.1%) and more adverse events such as renal dysfunction requiring temporary perioperative dialysis (p = 0.08) or bleeding (p = 0.06).
CONCLUSION: Although patients supported with HeartMate 3 have favourable survival, those with LVAD-DT have poorer outcomes. There is a need to better select patients eligible for LVAD-DT in order to limit the burden of adverse events and improve their prognosis.
AIMS OF THE STUDY: Limited knowledge exists regarding exposures to non-therapeutic chemicals by women planning to conceive, or during pregnancy or breastfeeding. The Swiss Teratogen Information Service (STIS) provides information to healthcare professionals about medications and other exposures during pregnancy or breastfeeding. This study aimed to describe the queries on non-therapeutic chemicals addressed to the STIS over the past two decades.
METHODS: Using data from the STIS for the years 2000 to 2019, we conducted a descriptive analysis of all queries related to women’s exposures to non-therapeutic chemicals during pregnancy planning, pregnancy or breastfeeding.
RESULTS: Over two decades, the STIS database recorded 320 exposures to chemicals. Workplace settings accounted for over 60% of queries, followed by exposures at home (20%). In almost half (48%) of the queries, more than one chemical was mentioned, totalling 885 chemicals across these 320 queries. Commonly mentioned chemicals included isopropanol, acetone and lead. Solvents were the leading category of products (16%), followed by cleaning products (10%), paints (8%) and insecticides (5%). The follow-up data showed five diverse cases of congenital malformations, accounting for 4.0% (5 out of 125) of the sample, a figure in line with the background risk of malformations in the general population.
CONCLUSIONS: This study emphasises the importance of conducting research that comprehensively captures the highly heterogeneous exposures to non-therapeutic chemicals during pregnancy and suggests that attention should be given not only to professional settings, but also to domestic contexts.
BACKGROUND: Non-pharmaceutical interventions during the COVID-19 pandemic caused an unusual epidemiology in bronchiolitis hospitalisations, with a peak in the summer seasons of 2020 and 2021.
AIM: The aim of this study was to analyse data from a 5-year period (2018–2022) at Hôpital du Jura in Delémont, Switzerland, regarding bronchiolitis hospitalisations before, during and towards the end of the COVID-19 pandemic in order to prepare for future changes in bronchiolitis epidemiology.
MATERIALS AND METHODS: Anonymous retrospective data on bronchiolitis hospitalisations for children under 2 years of age with hospital admission date from 1 January 2018 to 31 December 2022 was obtained from the Health Records Coding Unit of our hospital.
RESULTS: A clear shift in the peak of bronchiolitis is seen in 2021 compared to the three previous years. Starting in spring 2022, the trend begins to mimic pre-pandemic years. For respiratory syncytial virus (RSV) bronchiolitis hospitalisations specifically, an important peak in hospitalisations is seen in the summer months of 2021, with over 20 admissions, compared to zero admissions in the previous years. This peak shifts to the winter months in 2022.
CONCLUSIONS: The non-pharmacological interventions implemented during 2020 and early 2021 did not cause a long-lasting seasonal shift in bronchiolitis. In 2022, when the non-pharmacological interventions were no longer in place in the non-hospital setting, the peak of bronchiolitis hospitalisations is seen once again in the winter months. We predict that hospitalisation patterns will gradually revert to those of pre-pandemic years.
