Public History: Infrastructural Imaginaries and the Production of Affective Power.

This section of Public History explores "infrastructural imaginaries"-shared visions of future infrastructure that are collectively held and either publicly enacted or resisted. These imaginaries are deeply rooted in both present realities and past dreams of what could have been. For historians of technology, understanding who imagines this infrastructure, the impacts of these imaginings, and the emotional forces driving these processes is essential.

Relationship Between Objective and Subjective Markers of Muscle Recovery in Professional Handball Players.

Purpose: To evaluate the relationship between items of the Short Recovery and Stress Scale (SRSS) related to physical stress and recovery and the biomarker creatine kinase (CK) in professional handball.

Methods: CK and SRSS items (physical performance capability, overall recovery, muscular stress, and overall stress) were assessed in an observational study of 16 adult male professional handball players from a team in the highest German league during the 2019-20 preseason. Their preseason training schedule included several microcycles, each consisting of 3 consecutive days of intense training followed by a rest day.

Mini-open vs. arthroscopic double tight-rope reconstruction after acute AC-joint dislocation: a comparison in functional outcome and sports activity.

Introduction: In athletes, acromioclavicular joint disruptions account for up to 50% of all shoulder injuries. In high-grade injuries, surgery is favored to ensure a correct restoration of the joint, especially in young athletes. The aim of this study was to compare the clinical, radiological and sport related outcomes of the arthroscopic stabilization with the fixation of the AC joint in a mini-open approach.

[Revision of anatomic shoulder arthroplasty].

With the increasing number of primary arthroplasties, revisions of anatomical prostheses are becoming increasingly important. The most common reasons for revision are glenoid loosening, including protrusion, rotator cuff insufficiency, including instability, and early/late infection. The reconstruction of glenoid defects can be done with an autograft or allograft.

Biochemical Monitoring of Muscle Recovery in Elite Handball Using an Individualized Approach.

Purpose: To evaluate the classification performance of a new method to individualize reference ranges for biomarkers of muscle recovery in elite handball.

Methods: In a longitudinal observational study, creatine kinase (CK) and urea levels were assessed in 16 male elite handball players during the 2019-20 preseason. Blood samples were collected at prespecified time points when players were considered either recovered or nonrecovered.
