Abstract
This study evaluated patient's perception of recovery following surgical removal of mandibular third molars (SRM3s) including analyze of potential risk factors associated with impaired convalescent. Patient related parameters combined with preoperative questionnaires including Modified Dental Anxiety Scale, Oral Health Impact Profile-14, and Decayed, Missing, Filled Teeth index were correlated with questionnaires assessing pain, swelling, trismus, sick leave, social and working isolation, physical appearance, eating and speaking ability, diet variations, sleep impairment, impaired sensation of the lip, chin, and tongue, one month following SRM3s. Totally, 412 patients (223 females, 189 males) with mean age of 29.4 years were included. Treatment satisfaction and willingness to undergo similar surgery were reported by 92% and 95%, although 21% reported that the surgery and postoperative period had been worse than expected. Mean days with pain, sick leave, and swelling were 3.6, 2.1, and 3.6, respectively. Preoperative symptoms, dental anxiety level, and prolonged surgical time were associated with increased pain and swelling (P < 0.05). Pell and Gregory classification (I-IIIC) were associated with impaired sensation of the lower lip and chin (P < 0.05). Consequently, results from this study improve the surgeon's ability to predict parameters that predisposed to impaired recovery and neurosensory disturbances following SRM3s.

Abstract
BACKGROUND Asthma is a chronic airway disease, affecting over 300 million people worldwide. 5-10% of patients suffer from severe asthma and account for 50% of asthma-related financial burden. Availability of real-life data about the clinical course of severe asthma is insufficient. OBJECTIVES The aims of this study were to characterize patients with severe asthma in Switzerland, enrolled in the Swiss Severe Asthma Registry (SSAR), and evaluate predictors for asthma control. METHOD A descriptive characterisation of 278 patients was performed, who were prospectively enrolled in the registry until January 2022. Socio-demographic variables, comorbidities, diagnostic values, asthma treatment, and healthcare utilisation were evaluated. Groups of controlled and uncontrolled asthma according to the asthma control test were compared. RESULTS Forty-eight percent of patients were female and the mean age was 55.8 years (range 13-87). The mean body mass index (BMI) was 27.4 kg/m2 (±6). 10.8% of patients were current smokers. Allergic comorbidities occurred in 54.3% of patients, followed by chronic rhinosinusitis (46.4%) and nasal polyps (34.1%). According to the ACT score, 54.7% had well controlled, 16.2% partly controlled and 25.9% uncontrolled asthma. The most common inhalation therapy was combined inhaled corticosteroids/long-acting β2-agonists (78.8%). Biologics were administered to 81.7% of patients and 19.1% received oral steroids. The multivariable analysis indicated that treatment with biologics was positively associated with asthma control whereas higher BMI, oral steroids, exacerbations, and COPD were negative predictors for asthma control. CONCLUSION Biologics are associated with improved control in severe asthma. Further studies are required to complete the picture of severe asthma in order to provide improved care for those patients.

Abstract
Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung disorder with a complex clinical picture. The diagnosis may be difficult at times, as COPD may develop insidiously and remain unnoticed for a long time. Therefore, general practitioners play a central role in early detection of disease. Suspected COPD may be confirmed by further investigations in collaboration with a pulmonologist. The most recent GOLD guideline defines three COPD risk groups (A-B-E) which should guide the personalized treatment concept. General practitioners are crucial for implementing non-pharmacological measures such as smoking cessation, regular exercise, vaccinations, and patient self-management education. However, this also underlines the challenges to implement the GOLD recommendations in daily practice.

Abstract
COPD - An Underestimated Disease Abstract: Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung condition with a complex clinical picture. The diagnosis is not easy to make because COPD can develop insidiously and remain unnoticed for a long time. Therefore, general practitioners play a central role in the early detection of the disease. Suspected COPD can be confirmed by special examinations in collaboration with pulmonologists. The new GOLD guideline defines three COPD risk groups (A-B-E) which should guide the personalized treatment concept. A short- or long-acting bronchodilator (SAMA/SABA or LAMA/LABA) is recommended for group A, and a dual long-acting bronchodilator therapy (LABA+LAMA) is recommended for group B and E. In case of blood eosinophilia (≥300 cells/µl) and/or recent hospitalization for COPD exacerbation, triple therapy (LABA+LAMA+ICS) is recommended. General practitioners are important in implementing non-pharmacological measures (smoking cessation, regular exercise, vaccinations, patient selfmanagement education). However, this also underlines the high demands of the implementation of the GOLD guideline in daily practice.

Abstract
Background Basophils in acute asthma exacerbation are activated as evidenced by their increased expression levels of activation markers such as CD203c and CD63. However, whether basophils of allergic asthmatics who are in stable phase and have no asthma exacerbations display a specific and distinctive phenotype from those of healthy individuals has yet to be well characterized. Objective We aimed to identify the phenotype of basophils from allergic asthmatics in the stable phase and investigate whether such a phenotype is affected by ex vivo allergen stimulation. Methods We determined by flow cytometry, the expression of surface proteins such as CD25, CD32, CD63, CD69, CD203c, and CD300a and intracellular anti-apoptotic proteins BCL-2, BCL-xL, and MCL-1. We investigated these markers in blood basophils obtained from well-characterized patients with stable-mildly symptomatic form of allergic asthma with no asthma exacerbation and from healthy individuals. Moreover, we determined ex vivo CD63, CD69, and CD25 on blood basophils from stable-mildly symptomatic allergic asthmatics upon allergen stimulation. Results In contrast to all tested markers, CD25 was significantly increased on circulating basophils in the patient cohort with stable-mildly symptomatic allergic asthma than in healthy controls. The expression levels of CD25 on blood basophils showed a tendency to positively correlate with FeNO levels. Notably, CD25 expression was not affected by ex vivo allergen stimulation of blood basophils from stable-mildly symptomatic allergic asthma patients. Conclusion Our data identifies CD25 as a unique marker on blood basophils of the stable phase of allergic asthma but not of asthma exacerbation as mimicked by ex vivo allergen stimulation.

Abstract
For general practitioners there have been important novelties in the treatment of asthma due to recent modifications of the international guidelines from Global Initiative for Asthma (GINA). In Step 1, use of short-acting beta2-agonists (SABA) without concomitant inhaled corticosteroids (ICS) as controller is no longer recommended for lack of efficacy and safety reasons. Instead, low dose ICS-formoterol as needed is recommended. In Step 5, in patients with severe uncontrolled asthma GINA recommends targeted biologic therapies like interleukin antibodies. Asthma patients presenting simultaneously with symptoms of chronic obstructive pulmonary disease (COPD) should receive treatment containing ICS. Independent of the current corona pandemic, GINA recommendations stay in place.

Abstract
Machine learning has been advancing dramatically over the past decade. Most strides are human-based applications due to the availability of large-scale datasets; however, opportunities are ripe to apply this technology to more deeply understand non-human communication. We detail a scientific roadmap for advancing the understanding of communication of whales that can be built further upon as a template to decipher other forms of animal and non-human communication. Sperm whales, with their highly developed neuroanatomical features, cognitive abilities, social structures, and discrete click-based encoding make for an excellent model for advanced tools that can be applied to other animals in the future. We outline the key elements required for the collection and processing of massive datasets, detecting basic communication units and language-like higher-level structures, and validating models through interactive playback experiments. The technological capabilities developed by such an undertaking hold potential for cross-applications in broader communities investigating non-human communication and behavioral research.

Abstract
Objective To develop an automatic COVID-19 Reporting and Data System (CO-RADS)–based classification in a multi-demographic setting. Methods This multi-institutional review boards–approved retrospective study included 2720 chest CT scans (mean age, 58 years [range 18–100 years]) from Italian and Russian patients. Three board-certified radiologists from three countries assessed randomly selected subcohorts from each population and provided CO-RADS–based annotations. CT radiomic features were extracted from the selected subcohorts after preprocessing steps like lung lobe segmentation and automatic noise reduction. We compared three machine learning models, logistic regression (LR), multilayer perceptron (MLP), and random forest (RF) for the automated CO-RADS classification. Model evaluation was carried out in two scenarios, first, training on a mixed multi-demographic subcohort and testing on an independent hold-out dataset. In the second scenario, training was done on a single demography and externally validated on the other demography. Results The overall inter-observer agreement for the CO-RADS scoring between the radiologists was substantial (k = 0.80). Irrespective of the type of validation test scenario, suspected COVID-19 CT scans were identified with an accuracy of 84%. SHapley Additive exPlanations (SHAP) interpretation showed that the “wavelet_(LH)_GLCM_Imc1” feature had a positive impact on COVID prediction both with and without noise reduction. The application of noise reduction improved the overall performance between the classifiers for all types. Conclusion Using an automated model based on the COVID-19 Reporting and Data System (CO-RADS), we achieved clinically acceptable performance in a multi-demographic setting. This approach can serve as a standardized tool for automated COVID-19 assessment. Keypoints • Automatic CO-RADS scoring of large-scale multi-demographic chest CTs with mean AUC of 0.93 ± 0.04. • Validation procedure resembles TRIPOD 2b and 3 categories, enhancing the quality of experimental design to test the cross-dataset domain shift between institutions aiding clinical integration. • Identification of COVID-19 pneumonia in the presence of community-acquired pneumonia and other comorbidities with an AUC of 0.92.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic has put pressure on healthcare services, forcing the reorganisation of traditional care pathways. We investigated how physicians taking care of severe asthma patients in Europe reorganised care, and how these changes affected patient satisfaction, asthma control and future care. Methods In this European-wide cross-sectional study, patient surveys were sent to patients with a physician-diagnosis of severe asthma, and physician surveys to severe asthma specialists between November 2020 and May 2021. Results 1101 patients and 268 physicians from 16 European countries contributed to the study. Common physician-reported changes in severe asthma care included use of video/phone consultations (46%), reduced availability of physicians (43%) and change to home-administered biologics (38%). Change to phone/video consultations was reported in 45% of patients, of whom 79% were satisfied or very satisfied with this change. Of 709 patients on biologics, 24% experienced changes in biologic care, of whom 92% were changed to home-administered biologics and of these 62% were satisfied or very satisfied with this change. Only 2% reported worsening asthma symptoms associated with changes in biologic care. Many physicians expect continued implementation of video/phone consultations (41%) and home administration of biologics (52%). Conclusions Change to video/phone consultations and home administration of biologics was common in severe asthma care during the COVID-19 pandemic and was associated with high satisfaction levels in most but not all cases. Many physicians expect these changes to continue in future severe asthma care, though satisfaction levels may change after the pandemic.

Abstract
Novelties in the Treatment of Asthma Abstract. For general practitioners there have been important novelties in the treatment of asthma due to recent modifications of the international guidelines from Global Initiative for Asthma (GINA). Step 1 no longer recommends the use of short-acting β2-agonists (SABA) without concomitant inhaled corticosteroids (ICS) as a controller because of the lack of efficacy and for safety reasons. Instead, low dose ICS-formoterol as needed is recommended. GINA step 5 recommends targeted biologic therapies like interleukin antibodies in patients with severe uncontrolled asthma. Asthma patients presenting simultaneously with symptoms of chronic obstructive pulmonary disease (COPD) should receive treatment containing ICS. Independent of the current corona pandemic, GINA recommendations stay in place. Recent data on prescriptions of SABA and oral corticosteroids (OCS) in Switzerland indicate that they still play an important role in asthma management and that GINA recommendations have not yet been sufficiently implemented into practice.

Abstract
Cough - an Interdisciplinary Condition: The Pneumologist's Perspective Abstract. Cough is one of the most frequent reasons for a medical consultation. Patients mostly suffer from acute cough (< 2 weeks duration) and subacute cough (2 - 8 weeks) during consultation at primary care. Chronic cough (> 8 weeks) is mostly cared for by specialists. Acute and subacute cough is most frequently caused by infections with primarily viral pathogens. Chronic cough is commonly associated with obstructive airway disease (i. e. Asthma, COPD), gastroesophageal reflux and upper airway cough syndrome. Pulmonary causes are investigated by spirometry, bodyplethysmography, blood eosinophil count, exhaled nitric oxide, methacholine challenge test, chest x-rays and computed tomography. Treatment should target underlying diseases, causing cough. Trials of inhaled corticosteroids can be considered if an asthmatic cause is suspected. Secretolytics and cough-suppressing medications should be used only to reduce patient symptoms if there is no alternative causal treatment. Clinical trials show positive results for treatment of chronic refractory (no improvement of symptoms despite adequate treatment of the underlying condition) and chronic idiopathic cough with Gefapixant, a P2X3 purinergic receptor antagonist. If recent trial results are confirmed a first specific cough modulating substance might be available soon.

Abstract
Early detection of subclinical lung function impairment may enable a window of opportunity to slow down the progression of developing COPD [1, 2]. Single-breath carbon monoxide uptake in the lungs (DLCO) can be used as a screening test for mild lung function impairment in smokers [3]. Yet despite being readily used in common practice, the physiology is complex and depends on gas ventilation in the airways, diffusion through the alveolar membrane and the volume of haemoglobin in the capillaries supplying ventilated alveoli [4]. In smokers with preserved spirometry, DLCO is associated with ventilation inhomogeneity arising from peripheral airways. Measurement of DLCO to screen for early lung function abnormalities in smokers may be suboptimal and could be replaced by MBW.https://bit.ly/3nLmgg1

Abstract
It has been proposed that the effectiveness of non-invasive brain stimulation (NIBS) as a cognitive enhancement technique may be enhanced by combining the stimulation with concurrent cognitive activity. However, the benefits of such a combination in comparison to protocols without ongoing cognitive activity have not yet been studied. In the present study, we investigate the effects of fMRI-guided high-frequency repetitive transcranial magnetic stimulation (HF rTMS) over the left dorsolateral prefrontal cortex (DLPFC) on working memory (WM) in healthy volunteers, using an n-back task with spatial and verbal stimuli and a spatial span task. In two combined protocols (TMS + WM + (maintenance) and TMS + WM + (rest)) trains of stimuli were applied in the maintenance and rest periods of the modified Sternberg task, respectively. We compared them to HF rTMS without a cognitive load (TMS + WM −) and control stimulation (TMS − WM + (maintenance)). No serious adverse effects appeared in this study. Among all protocols, significant effects on WM were shown only for the TMS + WM − with oppositely directed influences of this protocol on storage and manipulation in spatial WM. Moreover, there was a significant difference between the effects of TMS + WM − and TMS + WM + (maintenance), suggesting that simultaneous cognitive activity does not necessarily lead to an increase in TMS effects.

Abstract
INTRODUCTION Treatment of condylar fractures in patients with atrophic edentulous mandibles is a peculiar field that has been little considered in the literature. The aim of the study was to assess the demographic and clinical variables as well as management and outcome of mandibular condylar fractures in edentulous patients with atrophic mandibles that were treated at several European departments of oral and maxillofacial surgery. METHODS The data of all patients with fractures of the atrophic edentulous mandible from the involved maxillofacial surgical units across Europe between January 1, 2008, and December 31, 2017. Only patients that were diagnosed with condylar fractures of the edentulous atrophic mandible were included. RESULTS A total of 52 patients met the inclusion criteria and were included in the study: 79% of patients reported one or more comorbidities. Thirty-four unilateral neck or subcondylar fractures, 9 bilateral neck or subcondylar condylar fractures, 7 unilateral head condylar fractures, and 2 bilateral head condylar fractures were diagnosed. No treatment was performed in 37 cases, whereas in 4 patients a closed treatment was decided, and 11 patients underwent open reduction and internal fixation. Outcome was considered to be satisfying in 48 patients, with no complications. CONCLUSIONS The golden rule still remains that the diagnosis of a subcondylar or neck fracture in an edentulous patient should constitute an indication for open reduction and internal fixation. However, an appropriate choice of management options has to be individualized on a case by case basis, also depending on the patient consent.

Abstract
INTRODUCTION The progressive aging of European population seems to determine a change in the epidemiology, incidence and etiology of maxillofacial fractures with an increase in the frequency of old patients sustaining craniofacial trauma. The objective of the present study was to assess the demographic variables, causes, and patterns of facial fractures in elderly population (with 70 years or more). MATERIALS AND METHODS The data from all geriatric patients (70 years or more) with facial fractures between January 1, 2013, and December 31, 2017, were collected. The following data were recorded for each patient: gender, age, voluptuary habits, comorbidities, etiology, site of facial fractures, synchronous body injuries, Facial Injury Severity Score (FISS). RESULTS A total of 1334 patients (599 male and 735 female patients) were included in the study. Mean age was 79.3 years, and 66% of patients reported one or more comorbidities. The most frequent cause of injury was fall and zygomatic fractures were the most frequently observed injuries. Falls were associated with a low FISS value (P<.005). Concomitant injuries were observed in 27.3% of patients. Falls were associated with the absence of concomitant injuries. The ninth decade (P<.05) and a high FISS score (P<.005) were associated with concomitant body injuries too. CONCLUSIONS This study confirms the role of falls in the epidemiology of facial trauma in the elderly, but also highlights the frequency of involvement of females, and the high frequency of zygomatic fractures.

Abstract
Purpose Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide and is associated with a growing and substantial socioeconomic burden. Long-term oxygen therapy (LTOT), recommended by current treatment guidelines for COPD patients with severe chronic hypoxemia, has shown to reduce mortality in this population. The aim of our study was to assess the standardized mortality ratios of incident and prevalent LTOT users and to identify predictors of mortality. Patients and methods We conducted a 2-year follow-up population-based cohort study comprising all COPD patients receiving LTOT in the canton of Bern, Switzerland. Comparing age- and sex-adjusted standardized mortality ratios, we examined associations between all-cause mortality and patient characteristics at baseline. To avoid immortal time bias, data for incident (receiving LTOT <6 months) and prevalent users were analyzed separately. Results At baseline, 475 patients (20% incident users, n=93) were receiving LTOT because of COPD (48/100,000 inhabitants). Mortality of incident and prevalent LTOT users was 41% versus 27%, respectively, p<0.007, and standardized mortality ratios were 8.02 (95% CI: 5.64–11.41) versus 5.90 (95% CI: 4.79–7.25), respectively. Type 2 respiratory failure was associated with higher standardized mortality ratios among incident LTOT users (60.57, 95% CI: 11.82–310.45, p=0.038). Conclusion Two-year mortality rate of COPD patients on incident LTOT was somewhat lower in our study than in older cohorts but remained high compared to the general population, especially in younger patients receiving LTOT <6 months. Type 2 respiratory failure was associated with mortality.

Abstract
We report the case of a 28-years-old woman with Turner's syndrome and iron deficiency anaemia. The faecal occult blood test was intermittently positive whereas earlier upper and lower endoscopy revealed no source of bleeding. Capsule endoscopy showed multiple vascular malformations on the jejunum and ileum. Our case report emphasizes the importance of capsule endoscopy in the localising occult bleedings in the small bowel. We discuss the different diagnostic modalities and possible treatments.

Abstract
We report the case of a 58-years-old soldier with a history of movement related neck pain, weight loss and exercise intolerance. Blood tests presented signs of an inflammatory syndrome. The CT-scan showed extended thickening of the aortic wall characteristic for aortitis. The diagnosis of giant cell arteritis could be histologically confirmed by biopsy of the temporal arteries. Our case report emphasizes the importance of the various imaging modalities. We discuss the different forms of disease evolution and the treatment regimen.

Abstract
We present the design for OpenPET, an electronics readout system designed for prototype radiotracer imaging instruments. The critical requirements are that it has sufficient performance, channel count, channel density, and power consumption to service a complete camera, and yet be simple, flexible, and customizable enough to be used with almost any detector or camera design. An important feature of this system is that each analog input is processed independently. Each input can be configured to accept signals of either polarity as well as either differential or ground referenced signals. Each signal is digitized by a continuously sampled ADC, which is processed by an FPGA to extract pulse height information. A leading edge discriminator creates a timing edge that is "time stamped" by a TDC implemented inside the FPGA. This digital information from each channel is sent to an FPGA that services 16 analog channels, and information from multiple channels is processed by this FPGA to perform logic for crystal lookup, DOI calculation, calibration, etc. As all of this processing is controlled by firmware and software, it can be modified / customized easily. The system is open source, meaning that all technical data (specifications, schematics and board layout files, source code, and instructions) will be publicly available.

Abstract
BACKGROUND The objective of this study was to determine the prevalence of glucose-6-phosphate dehydrogenase (G-6-PD) deficiency among the population of the Croatian Adriatic Coast, part of the Mediterranean basin. METHODS The fluorescent spot test was used to screen 2,726 randomly selected high school students in the Croatian Adriatic coastal area. Fluorescence readings were performed at the beginning and at 3, 6, 10, and 25 min of incubation. Results were classified into the following three groups: bright fluorescence (BF), weak fluorescence (WF), and no fluorescence (NF). All NF and WF samples at 3 min were quantitatively measured using the spectrophotometric method. RESULTS Twelve persons, 10 boys and 2 girls, were found to be deficient in G-6-PD, rendering a 0.44% prevalence of G-6-PD deficiency. All NF samples at fluorescent spot test were G-6-PD-deficient. WF at 3 min of the incubation period was present in 33 (1.2%) subjects, and only 2 (6%) were true positive. Fluorescence reading at 10 min of incubation omits five (41%) of the G-6-PD deficient samples. CONCLUSIONS Prevalence of G-6-PD deficiency in the Croatian Adriatic coastal population is 0.44%. Fluorescent spot test for moderate enzyme deficiency is reliable in early fluorescence reading.

Abstract
Angiogenin is one of the most potent inducers of neovascularization in experimental models in vivo. Angiogenin is normally present in plasma but overexpressed in cancer patients. The possible involvement of angiogenin in the development of cancer is suggested by its overexpression in patients with a variety of tumours and the observation that angiogenin antagonists prevent the growth of human tumour xenografts in athymic mice. This 14.1-kDa protein has 35% amino acid sequence identity with human pancreatic ribonuclease and displays ribonucleolytic activity. As only angiogenin is able to induce angiogenesis, its biological activities are thought to result from structural characteristics. Although the structural characteristics of angiogenin have been extensively studied, the understanding of its physiological role and of how its properties are expressed is still to be deciphered. This article reviews some of the biological, biochemical and structural properties of angiogenin.

Abstract
Records on 28 children (19 boys and 9 girls), mean age 3.1 years (range 6 months to 11 years), treated for foreign body aspiration (FBA) at the Department of Pediatrics, Split Clinical Hospital, during the 1992-1997 period, were analyzed. The mean hospital stay was 12.3 days (range 1 h to 92 days). History data on tracheobronchial FBA were available in 23 (82%) children. Radiologic findings pointed to FBA in 22 (77%) children. Rigid tracheobronchoscopy was performed in all patients, and proved successful in 26 (93%) of children. Digestible foreign bodies and food particles were removed in 22 (78%) children. Right-sided and left-sided bronchial FBA was recorded in 14 (50%) and 13 (46%) patients, respectively, whereas bilateral obstruction was present in one patient. The importance of suspected FBA in children with pronounced symptoms of coughing, dyspnea and choke is emphasized. Rigid tracheobronchoscopy and foreign body removal by forceps under anesthesia is an efficient and safe method, and we recommend its wider use in clinical practice.

Abstract
Effect of human prothymosin alpha and its mutant over-produced in S. cerevisiae on yeast cell division was studied. Wild-type prothymosin alpha appeared to block division of yeast cells. Its inhibitory action could be abolished by deletion of the last nine carboxy-terminal amino acids of prothymosin alpha containing nuclear localization signal, thus pointing to the nucleus as a compartment, where prothymosin alpha performs its action.

Abstract
Mycoplasma ovipneumoniae was isolated from sheep and lambs affected with a respiratory disease. It was established that the pneumonic disease caused by this organism was a severe one, with high mortality rate in young lambs. Adult sheep and older lambs remained chronically affected. Susceptibility varied, depending on the breed of the animals, some imported animals running a more severe course of the disease than the local ones. The disease was artificially induced in lambs at the joint infection with M. ovipneumoniae and P. haemolytica. The morphologic changes in the lungs consisted in a prevailing proliferation of the septal cells and polynuclear cells in the alveoli, an interseptal histiocyte proliferation, and a serous leukocyte infiltration.
