Abstract
BACKGROUND Histopathologic regression following neoadjuvant treatment (NT) of oesophageal cancer is a prognostic factor of survival, but the nodal status is not considered. Here, a score combining both to improve prediction of survival after neoadjuvant therapy is developed. METHODS Seven hundred and fifteen patients with oesophageal squamous cell (SCC) or adenocarcinoma (AC) undergoing NT and esophagectomy were analysed. Histopathologic response was classified according to percentage of vital residual tumour cells (VRTC): complete response (CR) without VRTC, major response with <10% VRTC, minor response with >10% VRTC. Nodal stage was classified as ypN0 and ypN+. Kaplan-Meier and Cox regression were used for survival analysis. RESULTS Survival analysis identified three groups with significantly different mortality risks: (1) low-risk group for CR (ypT0N0) with 72% 5-year overall survival (5y-OS), (2) intermediate-risk group for minor/major responders and ypN0 with 59% 5y-OS, and (3) high-risk group for minor/major responders and ypN+ with 20% 5y-OS (p < 0.001). Median survival in AC and SCC cohorts were comparable (3.8 (CI 95%: 3.1, 5.3) vs. 4.6 years (CI 95%: 3.3, not reached), p = 0.3). CONCLUSIONS Histopathologic regression and nodal status should be combined for estimating AC and SCC prognosis. Poor survival in the high-risk group highlights need for adjuvant therapy.

Abstract
Depending on the extent of gastric resection, namely total, proximal or distal gastrectomy, different methods of reconstruction are available. These reconstructive procedures have not changed with the implementation of minimally invasive or robotic techniques in general but the spectrum of possible anastomotic techniques has been substantially expanded. Functional, in particular nutritional disorders with subsequent impairment of the health-related quality of life, are often diagnosed after gastric resections. The partial preservation of a gastric reservoir has a positive impact on the extent of these disorders. After total gastrectomy, the placement of a jejunal pouch significantly reduces the incidence of postoperative dumping symptoms. Following proximal gastrectomy, double-tract reconstruction offers certain functional advantages as compared to the simple Roux‑Y reconstruction. In Germany, these reconstructive techniques are only used to a low extent and should be include in the repertoire of oncological gastric surgery with appropriate indications.

Abstract
Background Anastomotic leakage is the most important surgical complication following esophagectomy. A major cause of leakage is ischemia of the gastric tube that is used for reconstruction of the gastrointestinal tract. Generalized cardiovascular disease, expressed by calcifications of the aorta and celiac axis stenosis on a pre-operative CT scan, is associated with an increased risk of anastomotic leakage. Laparoscopic ischemic conditioning (ISCON) aims to redistribute blood flow and increase perfusion at the anastomotic site by occluding the left gastric, left gastroepiploic and short gastric arteries prior to esophagectomy. This study aims to assess the safety and feasibility of laparoscopic ISCON in selected patients with esophageal cancer and concomitant arterial calcifications. Methods In this prospective single-arm safety and feasibility trial based upon the IDEAL recommendations for surgical innovation, a total of 20 patients will be included recruited in 2 European high-volume centers for esophageal cancer surgery. Patients with resectable esophageal carcinoma (cT1-4a, N0–3, M0) with “major calcifications” of the thoracic aorta accordingly to the Uniform Calcification Score (UCS) or a stenosis of the celiac axis accordingly to the modified North American Symptomatic Carotid Endarterectomy Trial (NASCET) score on preoperative CT scan, who are planned to undergo esophagectomy are eligible for inclusion. The primary outcome variables are complications grade 2 and higher (Clavien-Dindo classification) occurring during or after laparoscopic ISCON and before esophagectomy. Secondary outcomes include intra- and postoperative complications of esophagectomy and the induction of angiogenesis by biomarkers of microcirculation and redistribution of blood flow by measurement of indocyanine green (ICG) fluorescence angiography. Discussion We hypothesize that in selected patients with impaired vascularization of the gastric tube, laparoscopic ISCON is feasible and can be safely performed 12–18 days prior to esophagectomy. Depending on the results, a randomized controlled trial will be needed to investigate whether ISCON leads to a lower percentage and less severe course of anastomotic leakage in selected patients.

Abstract
BACKGROUND In esophageal carcinoma, the numbers of metastatic and total removed lymph nodes (LN) are well-established variables of long-term prognosis. The overall rate of retrieved LN depends on neoadjuvant treatment, the extent of surgical lymphadenectomy, and the modality of the pathological workup. The question in this study is whether technically extended histopathological preparation can increase the number of detected (metastatic) LN with an impact on nodal UICC staging. PATIENTS AND METHODS A cohort of 77 patients with esophageal adenocarcinoma was treated with Ivor Lewis esophagectomy including standardized two-field lymphadenectomy. The specimens were grossed, and all manually detectable LN were retrieved. The remaining tissue was completely embedded by the advanced "acetone compression" retrieval technique. The primary outcome parameter was the total number of detected lymph nodes before and after acetone workup. RESULTS A mean number of 23,1 LN was diagnosed after standard manual LN preparation. With complete embedding of the fatty tissue using acetone compression, the number increased to 40.5 lymph nodes (p < 0.0001). The mean number of metastatic LN increased from 3.2 to 4.2 nodal metastases following acetone compression (p < 0.0001). Additional LN metastases which caused a change in the primary (y)pN stage were found in ten patients (13.0%). CONCLUSIONS Advanced lymph node retrieval by acetone compression allows a reliable statement on the real number of removed LN. Results demonstrate an impact on the nodal UICC stage. A future multicenter study will examine the prognostic impact of improved lymph node retrieval on long-term oncologic outcome.

Abstract
BACKGROUND AND OBJECTIVE Transthoracic esophagectomy is generally accepted as the standard of surgical care for patients with esophageal cancer. Despite improvements in the perioperative management this surgical procedure is associated with a clinically relevant morbidity. Fast-track protocols (synonym: enhanced recovery after surgery, ERAS) are conceived to perioperatively maintain the physiological homoeostasis and thereby to accelerate postoperative rehabilitation and reduce morbidity. In this prospective observational study the initial experiences of a high-volume center with the implementation of an ERAS protocol after transthoracic esophagectomy were analyzed. MATERIAL AND METHODS A total of 26 patients with esophageal cancer and a low index of comorbidities prior to hybrid Ivor Lewis esophagectomy were included in this study. According to an ERAS protocol all patients underwent a standardized perioperative treatment pathway aiming to discharge the patients from the inpatient treatment on postoperative day 10. The primary outcome parameter was the rate of major complications (Clavien-Dindo IIIb/IV), which was compared to a cohort of 52 non-ERAS patients. RESULTS AND CONCLUSION The ERAS programs with the various core elements can be implemented in patients scheduled for transthoracic esophagectomy, although the organizational and personnel expenditure of this fast-track protocol is high. The length of hospital stay appears to be reduced without compromising patient safety. The limiting variable of the ERAS protocol remains the early and adequate enteral feeding load of the gastric conduit before discharge on postoperative day 10.

Abstract
BACKGROUND Ivor-Lewis esophagectomy (ILE) is the standard surgical care for esophageal cancer patients but postoperative morbidity impairs quality of life and reduces long-term oncological outcome. Two-stage ILE separating the abdominal and thoracic phase into two distinct surgical procedures has proven to enhance microcirculation of the gastric conduit and therefore most likely reduces complications. However, two-stage ILE has not been evaluated systematically in selected groups of patients scheduled for this procedure. This investigation aims to demonstrate the feasibility of two-stage ILE in high-risk patients. PATIENTS AND METHODS In this retrospective analysis of data obtained from a prospective database, a consecutive series of 275 hybrid ILE (hILE) were included. Patients were divided into two groups based on one- or two-stage hILE. Postoperative complications were assessed according to ECCG (Esophageal Complication Consensus Group) criteria and compared using the Clavien-Dindo score. Indication for two-stage esophagectomy was classified as pre- or intraoperative decision. RESULTS 34 out of 275 patients (12.7%) underwent two-stage hILE. Patients of the two-stage group were significantly older. In 21 of 34 patients (61.8%) the decision for a two-stage procedure was made prior to esophagectomy, in 13 (38.2%) patients intraoperatively after completion of the laparoscopic gastric mobilization. The most frequent preoperative reason to select the two-stage procedure was a stenosis of the coeliac trunc and superior mesenteric artery (n = 10). The predominant cause for an intraoperative change of strategy was a laparoscopically diagnosed hepatic fibrosis/cirrhosis (n = 5).Overall morbidity and major' complications (CD > IIIa) were comparable for both groups (11.7% in both groups). The overall anastomotic leak rate was 12.4% and was non-significant lower for the two-stage procedure. CONCLUSION Two-stage hILE is a feasible concept to individualize the surgical treatment of patients with well-defined clinical risk factors for postoperative morbidity. It can also be applied after completion of the abdominal phase of IL esophagectomy without compromising the patient safety.

Abstract
Mechanical ventilation (MV) is an essential part of modern intensive care medicine. MV is performed in patients with severe respiratory failure caused by insufficiency of respiratory muscles and/or lung parenchymal disease when/after other treatments, (i. e. medication, oxygen, secretion management, continuous positive airway pressure or nasal highflow) have failed.MV is required to maintain gas exchange and to buy time for curative therapy of the underlying cause of respiratory failure. In the majority of patients weaning from MV is routine and causes no special problems. However, about 20 % of patients need ongoing MV despite resolution of the conditions which precipitated the need for MV. Approximately 40 - 50 % of time spent on MV is required to liberate the patient from the ventilator, a process called "weaning."There are numberous factors besides the acute respiratory failure that have an impact on duration and success rate of the weaning process such as age, comorbidities and conditions and complications acquired in the ICU. According to an international consensus conference "prolonged weaning" is defined as weaning process of patients who have failed at least three weaning attempts or require more than 7 days of weaning after the first spontaneous breathing trial (SBT). Prolonged weaning is a challenge, therefore, an inter- and multi-disciplinary approach is essential for a weaning success.In specialised weaning centers about 50 % of patients with initial weaning failure can be liberated from MV after prolonged weaning. However, heterogeneity of patients with prolonged weaning precludes direct comparisons of individual centers. Patients with persistant weaning failure either die during the weaning process or are discharged home or to a long term care facility with ongoing MV.Urged by the growing importance of prolonged weaning, this Sk2-guideline was first published in 2014 on the initiative of the German Respiratory Society (DGP) together with other scientific societies involved in prolonged weaning. Current research and study results, registry data and experience in daily practice made the revision of this guideline necessary.The following topics are dealt with in the guideline: Definitions, epidemiology, weaning categories, the underlying pathophysiology, prevention of prolonged weaning, treatment strategies in prolonged weaning, the weaning unit, discharge from hospital on MV and recommendations for end of life decisions.Special emphasis in the revision of the guideline was laid on the following topics:- A new classification of subgroups of patients in prolonged weaning- Important aspects of pneumological rehabilitation and neurorehabilitation in prolonged weaning- Infrastructure and process organization in the care of patients in prolonged weaning in the sense of a continuous treatment concept- Therapeutic goal change and communication with relativesAspects of pediatric weaning are given separately within the individual chapters.The main aim of the revised guideline is to summarize current evidence and also expert based- knowledge on the topic of "prolonged weaning" and, based on the evidence and the experience of experts, make recommendations with regard to "prolonged weaning" not only in the field of acute medicine but also for chronic critical care.Important addressees of this guideline are Intensivists, Pneumologists, Anesthesiologists, Internists, Cardiologists, Surgeons, Neurologists, Pediatricians, Geriatricians, Palliative care clinicians, Rehabilitation physicians, Nurses in intensive and chronic care, Physiotherapists, Respiratory therapists, Speech therapists, Medical service of health insurance and associated ventilator manufacturers.

Abstract
BACKGROUND In 2010, the ICF working group of Faculty II "Applied Social Medicine and Rehabilitation" of the German Society for Social Medicine and Prevention, DGSMP proposed a classification of personal factors (PF) for the German-speaking area. Meanwhile, the International Classification of Functioning, Disability and Health (ICF) and WHO's bio-psycho-social model were increasingly integrated into the German Social Code (Book IX for Rehabilitation and Participation). It was a legislative decision that the needs assessment for the rehabilitation process must be "comprehensive". AIM This publication aims to present an updated classification of PF to support the socio-medical assessment. For this purpose other published papers proposing a classification of PF were analyzed, especially the publication of Geyh et al. METHODS: The multiprofessional working group re-examined the basic structure, consistency and selection of factors of the 2010 classification using a qualitative approach and modified them if meaningful and necessary. The principles for the selection of factors were the same as in the 2010 publication (comprehensive, manageable, universal, impartial, relevant, unambiguous, focusing on finality, not regarding causality and non-discriminatory). RESULTS A fundamental revision was not necessary; the basic structure remained primarily unchanged. Some items were included, excluded, summarized, shifted and editorially or content-related altered. Legal expertise shows that the classification of PF and their individual use for the socio-medical assessment, if necessary for the individual rehabilitation allocation, incur no problems with regard to data-protection regulations. PERSPECTIVES The revised classification is ready to support users to describe and document relevant influences of the life background of individuals in a structured manner. Thus, influences on functioning and participation can be described comprehensively and transparently based on the bio-psycho-social model. A justiciable allocation of benefits for persons with disabilities is facilitated.

Abstract
BACKGROUND Allergen-specific immunotherapy (AIT) is the only causal treatment for allergy. However, success rates vary depending on the type of allergy and disease background of the patient. Hence, strategies targeting an increased therapeutic efficacy are urgently needed. Here, the effects of blockade of IL-4 and IL-13 signaling on different phases of AIT were addressed. METHODS The impact of the recombinantly produced IL-4 and IL-13 antagonist IL-4 mutein (IL-4M) on allergic sensitization and AIT outcome in experimental allergic asthma were analyzed in a murine model. The effects of IL-4M administration were assessed prior/during sensitization, immediately after AIT under allergen challenge, and two weeks post-treatment. RESULTS Intervention with IL-4M prior/during sensitization led to strong induction of IgG1, IgG2a, IgG2b, and IgG3, decrease of specific and total IgE, as well as of IL-5 in serum. Similar effects on the serum immunoglobulin levels were observed immediately after IL4M-supplemented AIT during allergen challenge. Additionally, IL4M markedly suppressed type-2 cytokine secretion of splenocytes beyond the effect of AIT alone. These effects were equaled to those of AIT alone two weeks post-treatment. Intriguingly, here, IL-4M induced a sustained decrease of Th2-biased Tregs (ST2+ FOXP3+ GATA3intermediate ). CONCLUSIONS IL-4 and IL-13 blockade during experimental AIT demonstrates beneficial effects on immunological key parameters such as immunoglobulin and cytokine secretion immediately after AIT. Although two weeks later these effects were dropped to those of AIT alone, the number of potentially disease-triggering Th2-biased Tregs was further significantly decreased by IL-4M treatment. Hence, IL-4/IL13-targeting therapies prime the immune memory in therapy success-favoring manner.

Abstract
Air pollution is growing fastest in monsoon-affected South Asia. During the dry winter monsoon, the fumes disperse toward the Indian Ocean, creating a vast pollution haze, but their fate during the wet summer monsoon has been unclear. We performed atmospheric chemistry measurements by aircraft in the Oxidation Mechanism Observations campaign, sampling the summer monsoon outflow in the upper troposphere between the Mediterranean and the Indian Ocean. The measurements, supported by model calculations, show that the monsoon sustains a remarkably efficient cleansing mechanism by which contaminants are rapidly oxidized and deposited to Earth's surface. However, some pollutants are lofted above the monsoon clouds and chemically processed in a reactive reservoir before being redistributed globally, including to the stratosphere.

Abstract
Dietary intake of methyl donors, such as folic acid and methionine, shows considerable intra-individual variation in human populations. While it is recognized that maternal departures from the optimum of dietary methyl donor intake can increase the risk for mental health issues and neurological disorders in offspring, it has not been explored whether paternal dietary methyl donor intake influences behavioral and cognitive functions in the next generation. Here, we report that elevated paternal dietary methyl donor intake in a mouse model, transiently applied prior to mating, resulted in offspring animals (methyl donor-rich diet (MD) F1 mice) with deficits in hippocampus-dependent learning and memory, impaired hippocampal synaptic plasticity and reduced hippocampal theta oscillations. Gene expression analyses revealed altered expression of the methionine adenosyltransferase Mat2a and BK channel subunit Kcnmb2, which was associated with changes in Kcnmb2 promoter methylation in MD F1 mice. Hippocampal overexpression of Kcnmb2 in MD F1 mice ameliorated altered spatial learning and memory, supporting a role of this BK channel subunit in the MD F1 behavioral phenotype. Behavioral and gene expression changes did not extend into the F2 offspring generation. Together, our data indicate that paternal dietary factors influence cognitive and neural functions in the offspring generation.

Abstract
Summary
Objectives: The Styrian Hospital Organization with 21 hospitals including the Graz University Hospital, and the Heidelberg University Hospital implemented a new HIS based on SAP/R3™, ISH™, ISH*MED™ with the objective to have an integrated system to support patient administration and management, patient care, clinical documentation, research etc.
Methods: Heidelberg University Hospital chose a step by step method for the introduction of the system, beginning with patient administration (ISH) and proceeding with clinical functions (ISH*MED). In Styria, the full functionality was implemented – as part of the selection process – in one peripheral hospital and in the Ear, Nose and Throat (ENT) Department of the Graz University Hospital, including special documents to support the processes in the highly specialized ENTunits.
Results and Conclusions: The standard modules are performant, stable and basically well accepted. Particularly in Graz, it has been shown that the requirements of highly specialized departments for work flow management, documentation and integration of subsystems and data from different sources can be fulfilled by special documents and programs – although at the expense of additional workload particularly in the initial phases of such a project.

Abstract
Noninvasive ventilation (NIV) may be used to treat pediatric acute respiratory failure. Recent improvements in ventilator technology and availability of nasal and full face masks for infants and children have simplified the use of NIV even in the smallest children. Mainly patients with hypercapnic respiratory failure may benefit from noninvasive ventilation. There is some evidence available that supports the use of NIV in viral bronchiolitis, asthma and acute on chronic respiratory failure in patients with neuromuscular or chronic pulmonary disease. Furthermore, noninvasive ventilation is beneficial during prolonged weaning from invasive ventilation and to treat upper airway obstructions. Children suffering from hypoxic respiratory failure, such as community-acquired pneumonia and acute respiratory distress syndrome do not benefit from NIV. Due to possibly relevant side effects and the possibility of rapid deterioration in gas exchange in failure of NIV, invasive ventilation should be readily available; therefore, treatment with noninvasive ventilation for acute respiratory failure in children should be initiated on the pediatric intensive care ward.

Abstract
A large variety of foregut symptoms can occur in patients with gastroesophageal reflux disease (GERD), which can overlap with other disorders such as somatoform disorders and dyspepsia. Due to unclear diagnostic situations, these patients are often not adequately treated. The aim of this study was the evaluation of patients with foregut symptoms, referred for possible antireflux surgery, regarding their relationship with GERD and somatization tendencies based on control data from an unselected population. Symptom evaluation and somatization screening were initiated both in volunteers and in patients with foregut symptoms and GERD. Unselected volunteers from a village population were also evaluated by symptom analysis and for somatisation tendency. In addition, patients with foregut symptoms were diagnosed for GERD, and symptom analysis and psychodiagnostic evaluation were performed. There is no major significant difference in the symptom-spectrum in patients with foregut symptoms, whether they have a proven pathologic acid exposure from GERD or not. The probability for the risk of somatization was 5.6% in the unselected population of nonpatient volunteers (n = 267). In patients with foregut symptoms (n = 750), the probability for the presence of somatoform tendencies was approximately 20%, independent whether these patients had a documented GERD or a normal esophageal acid exposure, implicating further diagnostic work-up for the selection of patients for antireflux surgery. There is a remarkable symptom load and variety in patients with GERD, in patients with foregut symptoms, and in an unselected population of volunteers. There is no difference in the risk for somatization between patients with foregut symptoms and those with documented GERD. Therapeutic decision making especially prior to antireflux surgery requires an awareness of mental and emotional challenges.

Abstract
Candidate genes for amelogenesis imperfecta (AI) and dentinogenesis imperfecta (DI) are located on 4q21 in humans. We tested our hypothesis that mutations in the portion of mouse chromosome 5 corresponding to human chromosome 4q21 would cause enamel and dentin abnormalities. Male C3H mice were injected with ethylnitrosourea (ENU). Within a dominant ENU mutagenesis screen, a mouse mutant was isolated with an abnormal tooth enamel (ATE) phenotype. The structure and ultrastructure of teeth were studied. The mutation was located on mouse chromosome 5 in an interval of 9 cM between markers D5Mit18 and D5Mit10. Homozygotic mutants showed total enamel aplasia with exposed dentinal tubules, while heterozygotic mutants showed a significant reduction in enamel width. Dentin of mutant mice showed a reduced content of mature collagen cross-links. We were able to demonstrate that a mutation on chromosome 5 corresponding to human chromosome 4q21 can cause amelogenesis imperfecta and changes in dentin composition.

Abstract
The non-invasive ventilation (NIV) is widespread in the clinical medicine and has attained meanwhile a high value in the clinical daily routine. The application of NIV reduces the length of ICU stay and hospitalization as well as mortality of patients with hypercapnic acute respiratory failure. Patients with acute respiratory failure in context of a cardiopulmonary edema should be treated in addition to necessary cardiological interventions with continuous positive airway pressure (CPAP) or NIV. In case of other forms of acute hypoxaemic respiratory failure it is recommended the application of NIV to be limited to mild forms of ARDS as the application of NIV in severe forms of ARDS is associated with higher rates of treatment failure and mortality. In weaning process from invasive ventilation the NIV reduces the risk of reintubation essentially in hypercapnic patients. A delayed intubation of patients with NIV failure leads to an increase of mortality and should therefore be avoided. With appropriate monitoring in intensive care NIV can also be successfully applied in pediatric patients with acute respiratory insufficiency. Furthermore NIV can be useful within palliative care for reduction of dyspnea and improving quality of life. The aim of the guideline update is, taking into account the growing scientific evidence, to outline the advantages as well as the limitations of NIV in the treatment of acute respiratory failure in daily clinical practice and in different indications.

Abstract
All mechanically ventilated patients must be weaned from the ventilator at some stage. According to an International Consensus Conference the criteria for "prolonged weaning" are fulfilled if patients fail at least 3 weaning attempts (i. e. spontaneous breathing trial, SBT) or require more than 7 days of weaning after the first SBT. This occurs in about 15 - 20 % of patients.Because of the growing number of patients requiring prolonged weaning a German guideline on prolonged weaning has been developed. It is an initiative of the German Respiratory Society (Deutsche Gesellschaft für Pneumologie und Beatmungsmedizin e. V., DGP) in cooperation with other societies (see acknowledgement) engaged in the field chaired by the Association of Scientific and Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF).This guideline deals with the definition, epidemiology, weaning categories, underlying pathophysiology, therapeutic strategies, the weaning unit, transition to out-of-hospital ventilation and therapeutic recommendations for end of life care. This short version summarises recommendations on prolonged weaning from the German guideline.

Abstract
BACKGROUND Noninvasive ventilation (NIV) may be superior to conventional therapy in immunocompromised children with respiratory failure. METHODS Mortality, success rate, prognostic factors and side effects of NIV for acute respiratory failure (ARF) were investigated retrospectively in 41 in children with primary immunodeficiency, after stem cell transplantation or chemotherapy for oncologic disease. RESULTS In 11/41 (27%) children invasive ventilation was avoided and patients were discharged from ICU. In children with NIV failure ICU-mortality was 19/30 (63%). 8/11 (72%) children with NIV success had recurrence of ARF after 27 days. Only 4/11 (36%) children with first episode NIV success and 8/30 (27%) with NIV failure survived to hospital discharge. Lower FiO2, SpO2/FiO2 and blood culture positive bacterial sepsis were predictive for NIV success, while fungal sepsis or culture negative ARF were predictive for NIV failure. We observed catecholamine treatment in 14/41 (34%), pneumothorax in 2/41 (5%), mediastinal emphysema in 3/41 (7%), a life threatening nasopharyngeal hemorrhage and need for resuscitation during intubation in 5/41 (12%) NIV-episodes. CONCLUSIONS The prognosis of ARF in immunocompromised children remains guarded independent of initial success or failure of NIV due to a high rate of recurrent ARF. Reversible causes like bacterial sepsis had a higher NIV response rate. Relevant side effects of NIV were observed.

Abstract
Supplemental oxygen is commonly provided during transition of neonates immediately after birth. Whereas an initial FiO2 of 0.21 is now recommended to stabilize full-term infants in the delivery room, the best FiO2 to start resuscitation of the very low birth weight infant (VLBWI) immediately after delivery is currently not known. Recent recommendations include the use of pulse oximetry to titrate the use of supplemental oxygen. As reference values for pulse oximetry during the first minutes of life have become available, automated FiO2-adjustments are feasible and may be very useful for delivery room care to limit oxygen exposure. Beyond neonatal transition, preterm infants in the neonatal intensive care unit (NICU) commonly require supplemental oxygen to avoid hypoxemia, especially VLBWI receiving respiratory support because of poor respiratory drive and/or lung disease. For respiratory care of newborn infants in the NICU automated FiO2-adjustment systems have been developed and have been studied in preterm infants for limited time frames using short-term physiological outcomes. These studies could demonstrate short-term benefits such as more stable arterial oxygen saturation. Recent clinical trials have shown that oxygen targeting may significantly affect mortality and morbidity. Therefore, randomized controlled trials are needed to study the effects of automated FiO2-adjustment on long-term outcomes to prove possible benefits on survival, the rate of retino-pathy of prematurity and on neuro-development-al outcome.
