    Abstract: Modern research methods enable unfolding the structure of the water column with higher resolution than ever, revealing the importance of submesoscale. Submesoscale processes have intermediate space and time scales of & lt;5 km and a few days in the Baltic Sea. A glider mission was conducted in the Gulf of Finland in May 2018. The appearance of a mesoscale front as a response to the persisting NE–E winds was observed. Within the front, smaller scale features at a lateral scale of a km were apparent. The tracer patterns indicated the presence of two adjacent motions – cold (warm) water penetrating upward (downward) on the lighter (denser) side of the front. We suggest they were traces of ageostrophic secondary circulation emerging while the loss of the upwelling-favorable forcing arrested the strengthening of the front. The analysis showed favorable conditions for the baroclinic and wind-driven instability. Such circulations could work to equalize the differences in cross-front direction, affecting the stratification and acting against the persistence of the mesoscale front. The spatial spectra of isopycnal tracer variance revealed the depth-dependence of the spectral slopes at the lateral scales of 1–10 km in the upper part of the water column. The differing of the slopes in the density layers associated with the mesoscale front indicates that frontal dynamics contribute to the energy cascade.

    Abstract: The acute respiratory distress syndrome (ARDS) is a life-threatening condition. In special situations, these critically ill patients must be transferred to specialized centers for escalating treatment. The aim of this study was to evaluate the quality of inter-hospital transport (IHT) of ARDS patients. Methods We evaluated medical and organizational aspects of structural and procedural quality relating to IHT of patients with ARDS in a prospective nationwide ARDS study. The qualification of emergency staff, the organizational aspects and the occurrence of critical events during transport were analyzed. Results Out of 1234 ARDS patients, 431 (34.9%) were transported, and 52 of these (12.1%) treated with extracorporeal membrane oxygenation. 63.1% of transferred patients were male, median age was 54 years, and 26.8% of patients were obese. All patients were mechanically ventilated during IHT. Pressure-controlled ventilation was the preferred mode (92.1%). Median duration to organize the IHT was 165 min. Median distance for IHT was 58 km, and median duration of IHT 60 min. Forty-two patient-related and 8 technology-related critical events (11.6%, 50 of 431 patients) were observed. When a critical event occurred, the PaO 2 /FiO 2 ratio before transport was significant lower (68 vs. 80 mmHg, p  = 0.017). 69.8% of physicians and 86.7% of paramedics confirmed all transfer qualifications according to requirements of the German faculty guidelines (DIVI). Conclusions The transport of critically ill patients is associated with potential risks. In our study the rate of patient- and technology-related critical events was relatively low. A severe ARDS with a PaO 2 /FiO 2 ratio  〈  70 mmHg seems to be a risk factor for the appearance of critical events during IHT. The majority of transport staff was well qualified. Time span for organization of IHT was relatively short. ECMO is an option to transport patients with a severe ARDS safely to specialized centers.

    Abstract: Acute respiratory distress syndrome (ARDS) is a life-threatening condition that often requires prolonged mechanical ventilation. Tracheostomy is a common procedure with some risks, on the other hand with potential advantages over orotracheal intubation in critically ill patients. This study investigated the association of tracheostomy with health-related quality of life (HRQoL), symptoms of psychiatric disorders and return-to-work of ARDS survivors. Methods Data were collected in the context of the prospective observational German-wide DACAPO study. Clinical and demographic patient data and treatment characteristics were obtained from the participating intensive care units (ICU). HRQoL and return-to-work were assessed using patient-reported questionnaires 3, 6 and 12 months after ICU discharge. HRQoL was measured with the Physical and Mental Component Scale of the Short-Form 12 Questionnaire (PCS-12, MCS-12). The prevalence of psychiatric symptoms (depression and post-traumatic stress disorder [PTSD]) was assessed using the Patient Health Questionnaire-9 and the Post-Traumatic Stress Syndrome-14. Physician-diagnosed anxiety and obsessive–compulsive disorder were recorded by patient self-report in the follow-up questionnaires. The associations of tracheostomy with HRQoL, psychiatric symptoms and return-to-work after 12 months were investigated by means of multivariable linear and logistic regression models. Results Primary 877 ARDS patients (mean ± standard deviation: 54 ± 16 years, 68% male) survived and were discharged from ICU. Out of these patients, 478 (54.5%) were tracheotomised during ICU treatment. After 12 months, patient-reported outcomes could be analysed of 388 (44.2%) respondents, 205 with tracheostomy and 183 without. One year after ICU discharge, tracheostomy showed no significant association with physical or mental health-related quality of life (PCS-12: − 0.73 [− 3.96, 2.51]; MCS-12: − 0.71 [− 4.92, 3.49] ), symptoms of psychiatric disorders (depression: 0.10 [− 1.43, 1.64]; PTSD: 3.31 [− 1.81, 8.43] ; anxiety: 1.26 [0.41, 3.86]; obsessive–compulsive disorder: 0.59 [0.05, 6.68] ) or return-to-work (0.71 [0.31, 1.64]) in the multivariable analysis (OR [95%-CI] ). Conclusions Up to 1 year after ICU discharge, neither HRQoL nor symptoms of psychiatric disorders nor return-to-work was affected by tracheostomy.

    Abstract: Abstract. Circulation plays an essential role in the creation of physical and biogeochemical fluxes in the Baltic Sea. The main aim of the work was to study the quasi-steady circulation patterns under prevailing forcing conditions. A total of 6 months of continuous vertical profiling and fixed-point measurements of currents, two month-long underwater glider surveys, and numerical modeling were applied in the central Baltic Sea. The vertical structure of currents was strongly linked to the location of the two pycnoclines: the seasonal thermocline and the halocline. The vertical movements of pycnoclines and velocity shear maxima were synchronous. The quasi-steady circulation patterns were in geostrophic balance and highly persistent. The persistent patterns included circulation features such as upwelling, downwelling, and boundary currents, as well as a sub-halocline gravity current. The patterns had a prevailing zonal scale of 5–60 km as well as considerably higher magnitude and different direction than the long-term mean circulation pattern. A northward (southward) geostrophic boundary current in the upper layer was observed along the eastern coast of the central Baltic in the case of southwesterly (northerly) wind. The geostrophic current at the boundary was often a consequence of wind-driven, across-shore advection. The sub-halocline quasi-permanent gravity current with a width of 10–30 km from the Gotland Deep to the north over the narrow sill separating the Fårö Deep and Nothern Deep was detected in the simulation, and it was confirmed by an Argo float trajectory. According to the simulation, a strong flow, mostly to the north, with a zonal scale of 5 km occurred at the sill. This current is an important deeper limb of the overturning circulation of the Baltic Sea. The current was stronger with northerly winds and restricted by the southwesterly winds. The circulation regime had an annual cycle due to seasonality in the forcing. The boundary current was stronger and more frequent northward during the winter period. The sub-halocline current towards the north was strongest in March–May and weakest in November–December.

    Abstract: Significant long-term reduction in health-related quality of life (HRQoL) is often observed in survivors of the acute respiratory distress syndrome (ARDS), and return to work (RtW) is limited. There is a paucity of data regarding the relationship between the quality of care (QoC) in the intensive care unit (ICU) and both HRQoL and RtW in ARDS survivors. Therefore, the aim of our study was to investigate associations between indicators of QoC and HRQoL and RtW in a cohort of survivors of ARDS. Methods To determine the influence of QoC on HRQoL and RtW 1 year after ICU-discharge, ARDS patients were recruited into a prospective multi-centre patient cohort study and followed up regularly after discharge. Patients were asked to complete self-report questionnaires on HRQoL (Short Form 12 physical component scale (PCS) and mental component scale (MCS)) and RtW. Indicators of QoC pertaining to volume, structural and process quality, and general characteristics were recorded on ICU level. Associations between QoC indicators and HrQoL and RtW were investigated by multivariable linear and Cox regression modelling, respectively. B values and hazard ratios (HRs) are reported with corresponding 95% confidence intervals (CIs). Results 877 (of initially 1225 enrolled) people with ARDS formed the DACAPO survivor cohort, 396 were finally followed up to 1 year after discharge. The twelve-month survivors were characterized by a reduced HRQoL with a greater impairment in the physical component (Md 41.2 IQR [34–52]) compared to the mental component (Md 47.3 IQR [33–57] ). Overall, 50% of the patients returned to work. The proportion of ventilated ICU patients showed significant negative associations with both 12 months PCS (B = − 11.22, CI −20.71; − 1,74) and RtW (HR = 0,18, CI 0,04;0,80). All other QoC indicators were not significantly related to outcome. Conclusions Associations between ICU QoC and long-term HrQoL and RtW were weak and largely non-significant. Residual confounding by case mix, treatment variables before or during ICU stay and variables pertaining to the post intensive care period (e.g. rehabilitation) cannot be ruled out.
