Abstract
Sepsis is a time dependent condition. Screening tools based on clinical parameters have been shown to increase the identification of sepsis. The aim of current study was to evaluate the additional predictive value of immunological molecular markers to our previously developed prehospital screening tools. This is a prospective cohort study of 551 adult patients with suspected infection in the ambulance setting of Stockholm, Sweden between 2017 and 2018. Initially, 74 molecules and 15 genes related to inflammation were evaluated in a screening cohort of 46 patients with outcome sepsis and 50 patients with outcome infection no sepsis. Next, 12 selected molecules, as potentially synergistic predictors, were evaluated in combination with our previously developed screening tools based on clinical parameters in a prediction cohort (n = 455). Seven different algorithms with nested cross-validation were used in the machine learning of the prediction models. Model performances were compared using posterior distributions of average area under the receiver operating characteristic (ROC) curve (AUC) and difference in AUCs. Model variable importance was assessed by permutation of variable values, scoring loss of classification as metric and with model-specific weights when applicable. When comparing the screening tools with and without added molecular variables, and their interactions, the molecules per se did not increase the predictive values. Prediction models based on the molecular variables alone showed a performance in terms of AUCs between 0.65 and 0.70. Among the molecular variables, IL-1Ra, IL-17A, CCL19, CX3CL1 and TNF were significantly higher in septic patients compared to the infection non-sepsis group. Combing immunological molecular markers with clinical parameters did not increase the predictive values of the screening tools, most likely due to the high multicollinearity of temperature and some of the markers. A group of sepsis patients was consistently miss-classified in our prediction models, due to milder symptoms as well as lower expression levels of the investigated immune mediators. This indicates a need of stratifying septic patients with a priori knowledge of certain clinical and molecular parameters in order to improve prediction for early sepsis diagnosis.Trial registration: NCT03249597.

Abstract
Visualization of cell migration via time-lapse microscopy has greatly advanced our understanding of the immune system. However, subtle differences in migration dynamics are easily obscured by biases and imaging artifacts. While several analysis methods have been suggested to address these issues, an integrated tool implementing them is currently lacking. Here, we present celltrackR, an R package containing a diverse set of state-of-the-art analysis methods for (immune) cell tracks. CelltrackR supports the complete pipeline for track analysis by providing methods for data management, quality control, extracting and visualizing migration statistics, clustering tracks, and simulating cell migration. CelltrackR supports the analysis of both 2D and 3D cell tracks. CelltrackR is an open-source package released under the GPL-2 license, and is freely available on both GitHub and CRAN. Although the package was designed specifically for immune cell migration data, many of its methods will also be of use in other research areas dealing with moving objects.

Abstract
The Ethics Section of the German Interdisciplinary Association of Critical Care and Emergency Medicine (DIVI) recently published a documentation for decisions to withhold or withdraw life-sustaining therapies. The wish to donate organs was not considered explicitly. Therefore the Ethics Section and the Organ Donation and Transplantation Section of the DIVI together with the Ethics Section of the German Society of Medical Intensive Care Medicine and Emergency Medicine worked out a supplementary footnote for the documentation form to address the individual case of a patient's wish to donate organs.

Abstract
OBJECTIVE In this study the effect of locally administered trapidil on human hand veins was examined. SUBJECTS 10 healthy male volunteers aged 20 - 30 years were included. METHOD The dorsal hand vein compliance technique was used. In a crossover design the influence of locally infused trapidil (mainly 5 - 400 microg/min) on hand veins preconstricted with either norepinephrine (adrenoceptor agonist) or dinoprost (prostaglandin F2alpha) was investigated. Preconstriction reduced the vein diameter by about 80% with continuous local infusion of individually determined doses of norepinephrine in the range 11 - 1,000 ng/min and dinoprost in the range 90 - 5,600 ng/min. Blood pressure, cardiac function (electrocardiogram) and skin temperature of the hand infused were monitored. RESULTS Locally applied trapidil produced a dose-dependent dilation of hand veins preconstricted with norepinephrine and dinoprost. The corresponding ED50 values of trapidil did not differ significantly on an intraindividual comparison. Clinically important side effects with the drugs used were not observed. CONCLUSIONS The results indicate that trapidil has a direct dilating action on superficial veins in humans. This effect is apparently achieved without involvement of adrenoceptors or prostanoid receptors in venous smooth muscle.

Abstract
A computerized system is described, combining automatic collection of urine in short intervals (minutes) over long periods (days) and recordings of body temperature, MABP, and heart rate in chronically instrumented conscious dogs. During the studies the dogs are housed in metabolic cages. Indwelling catheters and electrical wires are connected to a specially designed swivel and directed out of the cage to the next room. Infusions, blood sampling, and monitoring can be performed from this room without disturbance to the dogs. Three examples of recordings are given. In one of these examples the sodium excretion patterns on 5 consecutive days under continuous saline infusion in one dog is evaluated. Urine was collected every 20 min. Sodium excretion showed cyclic variations. Fourier analysis exhibited 18-h periods and 4- to 8-h periods. The described system renders, e.g., coherent time series analysis possible for a variety of simultaneously recorded physiological variables and may thus acquire considerable importance for integrative physiology.

Abstract
Vitreous prolapse in cataract surgery or during the extraction of a dislocated lens; corneal dystrophy in aphacic eyes due to corneo-vitreous contact and vitreous invading the anterior chamber following perforating injury proved to be valid indications for partial transpupillary vitrectomy. In malignant glaucoma, in postoperative wound rupture following cataract extraction, in open-sky-surgery of the anterior segment of aphacic eyes and in other particular conditions, transpupillary vitrectomy may also be considered. The transpupillary approach is not indicated in retinal detachment, unless prepupillary vitreous incarceration pulling up of the retina is obvious. Transpupillary vitrectomy can be performed without much harm to the eye even in children, if indicated (congenital cataract, congenital on traumatic lens dislocation, perforating lens injury). In general the results of transpupillary vitrectomy are good. Longterm complications are relatively rare. Experiences on 208 eyes are reported in particular.

Abstract
After introductory remarks concerning the Posner-Schlossman-syndrome (syndrome of glaucomatocyclitic crises) a case is reviewed. The concurrence with Addison's disease in this patient gives rise to speculations as to possible connections between the two conditions, but the conclusion is that the simultaneous occurrence of the two diseases at present must be regarded as coincidental.
