Plasma Rich in Growth Factors (PRGF) in the Treatment of Cervical and Lumbar Back Pain: A Retrospective Observational Clinical Study.

Background: Plasma rich in growth factors (PRGF) is a leukocyte-free platelet-rich plasma (PRP) that is an effective biological approach to tissue repair and has been demonstrated to significantly improve multiple conditions, including low back pain and degenerative disc pathology.

Objectives: The objective of this retrospective study was to analyze the effectiveness of treating both cervical and lumbar spine pain with minimally invasive infiltrations of PRGF-Endoret.

Study Design: Retrospective study design.

Modelling serial clustering and inter-annual variability of European winter windstorms based on large-scale drivers.

Winter windstorms are known to be among the most dangerous and loss intensive natural hazards in Europe. In order to gain a better understanding of their variability and driving mechanisms, this study analyses the temporal variability which is often referred to as serial or seasonal clustering. This is realized by developing a statistical model relating the winter storm counts to known teleconnection patterns affecting European weather and climate conditions (e.
