Numerous studies have investigated volume-outcome relationships in the treatment of very low birth weight infants. click here However, studies addressing the identification of optimal thresholds when introducing minimum provider volumes for treatment of these infants do not exist.

Publicly available data (www.perinatalzentren.org) of more than 56,000 infants weighing less than 1250 g at birth (NB<1250) and treated in level-1 perinatal centers (highest level in Germany) between 2010 and 2018 was used for statistical analysis. Potentially avoidable deaths after the introduction of minimum provider volumes were calculated by deducting observed deaths from estimated deaths based on logistic regression models for every existing empirical provider volume. Various smoothing functions were used to ascertain optimal thresholds for minimum provider volumes.

Independent of the observation period or smoothing technique, the highest number of potentially avoidable deaths was observed for minimum provider volumes of 50-60 NB<1250 per year. Introducing a minimum provider volume of 50 without a transition period would reduce the number of level-1 perinatal centers to a quarter of the current number in Germany. Approximately 60% of NB<1250 would have to be reallocated.

Analyses of resulting geographical distances are needed in the preparation of minimum provider volumes for treatment of NB<1250 in Germany. Such analyses should include perinatal centers expected to reach minimum provider volumes after subsequent reallocation in the future.

Analyses of resulting geographical distances are needed in the preparation of minimum provider volumes for treatment of NB less then 1250 in Germany. Such analyses should include perinatal centers expected to reach minimum provider volumes after subsequent reallocation in the future.Social media applications on smartphones allow for new avenues of instruction in sports medicine and exercise sciences. This study tested the feasibility of instructing health care personnel through videos of ultrasound vascular measurements distributed by a social media messenger application. After two training sessions with an ultrasound device, voluntary physicians (n=10) and nurses (n=10) received a video for the performance of an ultrasound-guided determination of intima-media-thickness and diameter of the femoral arteries via a social media messenger application. All participants examined the same healthy human subject. There was no significant difference between the groups regarding overall time of performance, measurements of the femoral arteries, or a specifically designed "assessment of mobile imparted arterial ultrasound determination" score. The physicians group achieved significantly higher scores in the established "objective structured assessment of ultrasound skills" score (p=0.019). Approval of the setting was high in both groups. click here Transmission of videos via social media applications can be used for instructions on the performance of ultrasound-guided vascular examinations in sports medicine, even if investigators' performances differ depending on their grade of ultrasound experience. In the future, the chosen approach should be tested in practical scientific examination settings.The coronavirus disease 2019 (COVID-19) pandemic has forced primary/grade schools and university closings as well as forced the suspension of a number of medical and laboratory testing procedures. Exercise science laboratories whether in clinical, research or educational locations were also forced to pause testing procedures. As the COVID-19 pandemic begins to subside in some areas of the world, exercise science laboratories are contemplating how to create a safe environment to resume some laboratory testing activities. In this article, we present suggestions for how exercise science laboratories can open and create a safe environment for subjects, laboratory personnel and equipment upon reopening.The purpose of this study was to describe the mechanical and metabolic responses of a typical high-intensity training session in high-level 800-m athletes. Nine male high-level 800-m athletes (personal best 143-156 minss) performed a typical high-intensity interval training session consisting of 5×200 m with 4 min rest. Countermovement jump and blood lactate were measured at rest and after each running bout. Running times, ground contact times, and stride length were also measured. Running times and lactate (p less then 0.01) progressively increased from the first to the last running bout. Jump height (p less then 0.01) and stride length (p less then 0.05) progressively decreased from the first running bout to the last. A significant negative relationship (p less then 0.001; r =-0.83) was found between the individual values of jumping height and blood lactate concentration; and a significant positive relationship (p less then 0.01; r=0.67) was observed between the time in the 200 m and the contact times. In conclusion, the results demonstrated that the typical training session performed by 800-m athletes produced a high level of fatigue as evidenced by significant alterations in the mechanical and metabolic response. The impairments observed in the mechanical and metabolic parameters may indirectly reflect a state of energy deficit of the muscle contractile machinery and a reduction of the force-generating capacity.
