Disease characteristics and clinical outcome over two decades from the Swiss pulmonary hypertension registry
Pulmonary hypertension (PH), especially pulmonary arterial and chronic thromboembolic pulmonary hypertension (PAH/CTEPH), are rare and progressive conditions. Despite recent advances in treatment and prognosis, PH is still associated with impaired quality of life and survival. Long-term PH-registry data provide information on the changing PH-epidemiology and may help to direct resources to patient's needs. This retrospective analysis of the Swiss Pulmonary Hypertension Registry includes patients newly diagnosed with PH (mainly PAH/CTEPH) registered from January 2001 to June 2019 at 13 Swiss hospitals. Patient characteristics (age, body mass index, gender, diagnosis), hemodynamics at baseline, treatment, days of follow-up, and events (death, transplantation, pulmonary endarterectomy, or loss to follow-up) at last visit were analyzed. Patients were stratified into four time periods according to their date of diagnosis. Survival was analyzed overall and separately for PAH/CTEPH and time periods. 1427 PH patients were included (thereof 560 PAH, 383 CTEPH). Over the years, age at baseline (mean ± SD) significantly increased from 59 ± 14 years in 2001–2005 to 66 ± 14 years in 2016–2019 (p < 0.001) while the gender distribution tended toward equality. Mean pulmonary artery pressure and pulmonary vascular resistance significantly decreased over time (from 46 ± 15 to 41 ± 11 mmHg, respectively, 9 ± 5 to 7 ± 4 WU, p < 0.001). Three-year survival substantially increased over consecutive periods from 69% to 91% (for PAH 63%–95%, for CTEPH 86%–93%) and was poorer in PAH than CTEPH independently of time period (p < 0.001). Most patients were treated with mono- or combination therapy and an increasing number of CTEPH underwent pulmonary endarterectomy (40% 2016–2019 vs. 15% 2001–2005). This long-term PH registry reveals that over two decades of observation, newly diagnosed patients are older, less predominantly female, have less impaired hemodynamics and a better survival

Therapeutic bronchoscopy for malignant airway stenoses: Choice of modality and survival
Background: There are no data regarding the factors influencing the
choice of therapeutic bronchoscopic modality in the management of
malignant airway stenoses. Objectives: To assess the choice of
therapeutic bronchoscopy modality and analyze factors influencing
survival in patients with malignant central airway obstruction.
Materials and Methods: We performed 167 procedures in 130 consecutive
patients, for malignant central airway obstruction, over six years.
Results: Laser was used either alone or in combination with stent
insertion in 76% procedures. Laser only was used in 53% procedures for
lesions below the main bronchi. Stents alone were used for extrinsic
compression or stump insufficiency. Combined laser and stent insertion
was most frequently used for lesions involving the trachea plus both
main bronchi or only the main bronchi. The Dumon stent was preferred in
lesions of the trachea and the right bronchial tree, the Ultraflex
stent for lesions on the left side and stenoses below the main bronchi.
Survival was better in patients with lung cancer, lesions restricted to
one lung and when laser alone was used compared to esophageal cancer,
metastases and tracheal involvement. Conclusion: The choice of
different airway stents can be made based on the nature and site of the
lesion. Dumon stents are suited for lesions in trachea and right main
bronchus and the Ultraflex stents on the left side and stenoses beyond
the main bronchi. Survival can be estimated based on the diagnosis,
site of the lesion and treatment modality used
Indacaterol and glycopyrronium versus indacaterol on body plethysmography measurements in COPD-a randomised controlled study.
BACKGROUND
Dual bronchodilator therapy is recommended for symptomatic patients with chronic obstructive pulmonary disease (COPD). There are limited data on effects of a combination of two long-acting bronchodilators on lung function including body plethysmography.
METHODS
This multicentre, randomised, double-blind, single-dose, cross-over, placebo-controlled study evaluated efficacy and safety of the free combination of indacaterol maleate (IND) and glycopyrronium bromide (GLY) versus IND alone on spirometric and body plethysmography parameters, including inspiratory capacity (IC), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), total lung capacity (TLC) and airway resistance (Raw) in moderate-to-severe COPD patients.
RESULTS
Seventy-eight patients with FEV1 % pred. (mean ± SD) 56 ± 13% were randomised. The combination of IND + GLY versus IND presented a numerically higher peak-IC (Δ = 0.076 L, 95% confidence interval [CI]: -0.010 - 0.161 L; p = 0.083), with a statistically significant difference in mean IC over 4 h (Δ = 0.054 L, 95%CI 0.022 - 0.086 L; p = 0.001). FEV1, FVC and Raw, but not TLC, were consistently significantly improved by IND + GLY compared to IND alone. Safety profiles of both treatments were comparable.
CONCLUSION
The free combination of IND + GLY improved lung function parameters as evaluated by spirometry and body plethysmography, with a similar safety profile compared to IND alone.

The Swiss Approach - feasibility of a national low-dose CT lung cancer screening program.
BACKGROUND
Lung cancer is the leading cause of cancer-related deaths in Switzerland. Despite this, there is no lung cancer screening program in the country. In the United States, low-dose computed tomography (LDCT) lung cancer screening is partially established and endorsed by guidelines. Moreover, evidence is growing that screening reduces lung cancer-related mortality and this was recently shown in a large European randomized controlled trial. Implementation of a lung cancer screening program, however, is challenging and depends on many country-specific factors. The goal of this article is to outline a potential Swiss lung cancer screening program.
FRAMEWORK
An exhaustive literature review on international screening models as well as interviews and site visits with international experts were initiated. Furthermore, workshops and interviews with national experts and stakeholders were conducted to share experiences and to establish the basis for a national Swiss lung cancer screening program.
SCREENING APPROACH
General practitioners, pulmonologists and the media should be part of the recruitment process. Decentralisation of the screening might lead to a higher adherence rate. To reduce stigmatisation, the screening should be integrated in a "lung health check". Standardisation and a common quality level are mandatory. The PLCOm2012 risk calculation model with a threshold of 1.5% risk for developing cancer in the next six years should be used in addition to established inclusion criteria. Biennial screening is preferred. LUNG RADS and NELSON+ are applied as classification models for lung nodules.
CONCLUSION
Based on data from recent studies, literature research, a health technology assessment, the information gained from this project and a pilot study the Swiss Interest Group for lung cancer screening (CH-LSIG) recommends the timely introduction of a systematic lung cancer screening program in Switzerland. The final decision is for the Swiss Cancer Screening Committee to make

Unpublished Mediterranean and Black Sea records of marine alien, cryptogenic, and neonative species
To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara.

Fatal cerebral air embolism following uneventful flexible bronchoscopy
Flexible bronchoscopy is a widely used and safe procedure with a reported maximal mortality rate of 0.04% and a major-complications rate of 0.5%. There are, however, only few case descriptions for postinterventional cerebral air embolism and the frequency of this supposedly rare complication is unknown. The current study presents 2 patients with non-small cell lung cancer who suffered fatal cerebral air embolism following diagnostic bronchoscopy with transbronchial needle aspiration and transbronchial biopsy, resulting in a frequency of >0.02% for this severe complication in our institution. In addition to early supportive measures, 1 patient received hyperbaric oxygen therapy as further treatment. Prompt recognition of this complication is mandatory in order to implement appropriate supportive measures. High-flow oxygen should be administered and hyperbaric oxygen therapy may be considered, if available. If possible, positive pressure ventilation should be avoided
