Abstract
Zusammenfassung
Hintergrund Um die Folgen der Progression von Mukoviszidose möglichst gering zu halten, benötigen Patient*innen ein Konzept für lebenslange medikamentöse Interventionen und intensive Physiotherapie, gepaart mit einer sehr hohen Therapie-Adhärenz. Durch die Erhöhung der durchschnittlichen Lebenswartung auf über 50 Jahre bei über der Hälfte der Betroffenen stehen medizinische Fachkräfte vor neuen Herausforderungen bei der Versorgung. Die nötigte Implementierung von Übergangsprogrammen für junge Erwachsene, aus den Kinderambulanzen heraus, sind jedoch noch immer nicht flächendeckend vollzogen. Niedrige Raten bei der Adhärenz verdeutlichen die problematische Situation.
Ziel Erfassung der Wahrnehmung von jungen Erwachsenen mit Mukoviszidose in Bezug auf Faktoren, die einen Einfluss auf ihre Therapie-Adhärenz haben.
Methode Das Erleben der Behandlungen sowie die Adhärenz beeinflussenden Faktoren wurden anhand von Leitfadeninterviews (n = 10) erhoben. Die Auswertung erfolgte mithilfe der inhaltlich strukturierenden Inhaltsanalyse nach Kuckartz.
Ergebnisse Es zeigt sich ein komplexes Gesamtbild von Einflussfaktoren, mit einem auffälligen Wechselverhalten zwischen Adhärenz und Non-Adhärenz zu medizinisch notwendigen Therapien. Aus Sicht der Befragten ist die partizipative Entscheidungsfindung der zentrale Ansatzpunkt zur Förderung der Adhärenz, Minderung des Wechselverhaltens und Stärkung der Bewältigung und Aufrechterhaltung von Selbstwirksamkeit.
Schlussfolgerung Die Ergebnisse geben Implikationen für die Ausbildung von Physiotherapeut*innen und Mediziner*innen bezüglich theoretischer Grundlagen zum Gesundheitsverhalten, zur Verhaltensänderung, Adhärenz und zu Entscheidungsprozessen von Patient*innen.

Abstract
The nasal mucosa functions as a frontline biological defense against various foreign substances and pathogens. Maintaining homeostasis of the nasal epithelium is necessary to promote good health. Nasal epithelia are constantly replaced under normal conditions. However, hereditary diseases, including primary ciliary dyskinesia and cystic fibrosis, can result in intractable dysfunction of the nasal mucosa. Since there is no treatment for this underlying condition, extrinsic manipulation is necessary to recover and maintain nasal epithelia in cases of hereditary diseases. In this study, we explored the use of airway epithelial cells (AECs), including multi-ciliated airway cells (MCACs), derived from human induced pluripotent stem cells (hiPSCs) on porcine atelocollagen vitrigel membranes, as a candidate of a therapeutic method for irreversible nasal epithelial disorders. To confirm the regenerative capacity of iPSC-derived AECs, we transplanted them into nasal cavities of nude rats. Although the transplanted cells were found within cysts isolated from the recipient nasal respiratory epithelia, they survived in some rats. Furthermore, the surviving cells were composed of multiple cell types similar to the human airway epithelia. The results could contribute to the development of novel transplantation-related technologies for the treatment of severe irreversible nasal epithelial disorders.

Abstract
Cystic fibrosis (CF) is a chronic disease causing severe impairment to the respiratory system and digestive tracts. Currently, CF is incurable. As an autosomal recessive disorder, the morbidity of CF is significantly higher among Caucasians of European descent, whereas it is less pervasive among African and Asian populations. The disease is caused by identical mutations (homozygosity) or different mutations (heterozygosity) of an autosomal recessive mutation at position 7q31.2-q31.1 of chromosome 7. Diagnostic criteria and guidelines work concurrently with laboratory detection to facilitate precise CF detection. With technological advances, the understanding of CF pathogenesis has reached an unprecedented level, allowing for increasingly precise carrier screening, more effective early stage CF intervention and improved prognostic outcomes. These advances significantly increase the life quality and expectancy of patients with CF. Given the numerous improvements in the field of CF, the current review summarized the technical advances in the study of the molecular mechanisms underlying CF, as well as how these improvements facilitate the clinical outcomes of CF. Furthermore, challenges and obstacles to overcome are discussed.

Abstract
Glycoconjugates are the most diverse biomolecules of life. Mostly located at the cell surface, they translate into cell-specific "barcodes" and offer a vast repertoire of functions, including support of cellular physiology, lifestyle, and pathogenicity. Functions can be fine-tuned by non-carbohydrate modifications on the constituting monosaccharides. Among these modifications is pyruvylation, which is present either in enol or ketal form. The most commonly best-understood example of pyruvylation is enol-pyruvylation of N-acetylglucosamine, which occurs at an early stage in the biosynthesis of the bacterial cell wall component peptidoglycan. Ketal-pyruvylation, in contrast, is present in diverse classes of glycoconjugates, from bacteria to algae to yeast-but not in humans. Mild purification strategies preventing the loss of the acid-labile ketal-pyruvyl group have led to a collection of elucidated pyruvylated glycan structures. However, knowledge of involved pyruvyltransferases creating a ring structure on various monosaccharides is scarce, mainly due to the lack of knowledge of fingerprint motifs of these enzymes and the unavailability of genome sequences of the organisms undergoing pyruvylation. This review compiles the current information on the widespread but under-investigated ketal-pyruvylation of monosaccharides, starting with different classes of pyruvylated glycoconjugates and associated functions, leading to pyruvyltransferases, their specificity and sequence space, and insight into pyruvate analytics.

Abstract
Introduction The impact of glutathione on pulmonary function remains elusive for patients with cystic fibrosis. The aim of this systematic review and meta-analysis is to explore the influence of glutathione versus placebo on pulmonary function of cystic fibrosis. Methods We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through May 2019, and randomized-controlled trials (RCTs) regarding the effect of glutathione on pulmonary function of cystic fibrosis are included in this meta-analysis. Results Four RCTs are included. Compared with control group in patients with cystic fibrosis, glutathione treatment shows positive impact on forced expiratory volume 1 second (FEV1) (mean difference [MD] = 0.19; 95% confidence interval (CI), 0.10–0.28; P < .0001) and body mass index (MD = 0.27; 95% CI, 0.02–0.51; P = .03), but has no obvious influence on 6-minute walk test (standard MD = 0.28; 95% CI, −0.08 to 0.64; P = .13), number of exacerbations (MD = −0.10; 95% CI, −0.34 to 0.15; P = .43), abdominal pain or distal intestinal obstruction (risk ratios [RR] = 0.78; 95% CI, 0.32–1.90; P = .58), or hemoptysis (RR = 1.87; 95% CI, 0.43–8.26; P = .41). Conclusions Glutathione treatment provides some benefits to improve pulmonary function of patients with cystic fibrosis, as evidenced by the increase in FEV1.

Abstract
Cystic fibrosis (CF) is an autosomal recessive disease caused by CFTR mutations. It is characterized by high NaCl concentration in sweat and the production of a thick and sticky mucus, occluding secretory ducts, intestine and airways, accompanied by chronic inflammation and infections of the lungs. This causes a progressive and lethal decline in lung function. Therefore, finding the mechanisms driving the high susceptibility to lung infections has been a key issue. For decades the prevalent hypothesis was that a reduced airway surface liquid (ASL) volume and composition, and the consequent increased mucus concentration (dehydration), create an environment favoring infections. However, a few years ago, in a pig model of CF, the Na+/K+ concentrations and the ASL volume were found intact. Immediately a different hypothesis arose, postulating a reduced ASL pH as the cause for the increased susceptibility to infections, due to a diminished bicarbonate secretion through CFTR. Noteworthy, a recent report found normal ASL pH values in CF children and in cultured primary airway cells, challenging the ASL pH hypothesis. On the other hand, recent evidences revitalized the hypothesis of a reduced ASL secretion. Thus, the role of the ASL pH in the CF is still a controversial matter. In this review we discuss the basis that sustain the role of CFTR in modulating the extracellular pH, and the recent results sustaining the different points of view. Finding the mechanisms of CFTR signaling that determine the susceptibility to infections is crucial to understand the pathophysiology of CF and related lung diseases.

Abstract
Imaging holds an important role in the diagnosis of lung diseases. Along with clinical tests, noninvasive imaging techniques provide complementary and valuable information that enables a complete differential diagnosis. Various novel molecular imaging tools are currently under investigation aimed toward achieving a better understanding of lung disease physiopathology as well as early detection and accurate diagnosis leading to targeted treatment. Recent research on molecular imaging methods that may permit differentiation of the cellular and molecular components of pulmonary disease and monitoring of immune activation are detailed in this review. The application of molecular imaging to lung disease is currently in its early stage, especially compared to other organs or tissues, but future studies will undoubtedly reveal useful pulmonary imaging probes and imaging modalities.

Abstract
Pseudomonas aeruginosa is a gram-negative pathogen, which causes life-threatening infections in immunocompromized patients. These bacteria express a secreted lipoxygenase (PA-LOX), which oxygenates free arachidonic acid to 15S-hydro(pero)xyeicosatetraenoic acid. It binds phospholipids at its active site and physically interacts with lipid vesicles. When incubated with red blood cells membrane lipids are oxidized and hemolysis is induced but the structures of the oxygenated membrane lipids have not been determined. Using a lipidomic approach, we analyzed the formation of oxidized phospholipids generated during the in vitro incubation of recombinant PA-LOX with human erythrocytes and cultured human lung epithelial cells. Precursor scanning of lipid extracts prepared from these cells followed by multiple reaction monitoring and MS/MS analysis revealed a complex mixture of oxidation products. For human red blood cells this mixture comprised forty different phosphatidylethanolamine and phosphatidylcholine species carrying oxidized fatty acid residues, such as hydroxy-octadecadienoic acids, hydroxy- and keto-eicosatetraenoic acid, hydroxy-docosahexaenoic acid as well as oxygenated derivatives of less frequently occurring polyenoic fatty acids. Similar oxygenation products were also detected when cultured lung epithelial cells were employed but here the amounts of oxygenated lipids were smaller and under identical experimental conditions we did not detect major signs of cell lysis. However, live imaging indicated an impaired capacity for trypan blue exclusion and an augmented mitosis rate. Taken together these data indicate that PA-LOX can oxidize the membrane lipids of eukaryotic cells and that the functional consequences of this reaction strongly depend on the cell type.
