Enhanced Pain Reduction at Different Stages of Knee Osteoarthritis via Repeated Injections of Hyaluronic Acid with Niacinamide: A Comparative Study.

Osteoarthritis (OA) of the knee is the most common joint disease, characterized by the degeneration of joint cartilage. Intra-articular hyaluronic acid (IAHA) injections are a well-established non-surgical treatment. This retrospective study analyzed knee OA patients receiving IAHA combined with niacinamide injections, assessing pain reduction in relation to patient data, the number of injections, and radiological findings.

Investigating Painkiller Use in Amateur Football: A Coach's Perspective.

Background/objectives: Painkiller use in amateur sports and, especially, in football is increasingly being discussed, but the scientific data on this field are very limited. Therefore, the aim of this study was to investigate the prevalence of painkiller use in amateur football from the perspective of coaches, as well as to determine how and to which extent coaches can influence their teams in terms of painkiller use and prevention.

Methods: Using an online questionnaire, a cross-sectional analysis of painkiller use in German amateur football from the 4th league to the lowest amateur classes was carried out from the perspective of team coaches.

Head-Shaft Angle Influences Isometric Shoulder Strength Levels after Intramedullary Nailing of Proximal Humerus Fractures: A Pilot Study.

Background: Proximal humerus fractures are common fractures of the elderly population which can lead to long-term compromise of a patient's shoulder function. Closed reduction and internal fixation with intramedullary nailing is a well-established surgical technique yielding good outcomes, as perceived by patients, obtained via Patient-Reported Outcome Measures, and objectified by clinical shoulder testing. Apart from conventional range-of-motion testing and clinical shoulder tests, strength testing of the shoulder is a yet-neglected but meaningful and standardizable outcome parameter.

Lipogenesis in Nasonia vitripennis: Influence of sugar chemistry, preferential production of triacylglycerides, and comparison of fatty acid biosynthetic capacity with Drosophilamelanogaster.

Sugar consumption increases the fecundity and longevity in many species of parasitic wasps (parasitoids) but whether these insects use sugars to synthesize significant amounts of fatty acids and storage fat de novo (lipogenesis) is discussed controversially. It has long been assumed that parasitic wasps lost this ability during evolution, mainly because in several species wasps with ad libitum access to sugar did not increase teneral lipid levels. Recent studies demonstrated that many species are nonetheless capable of synthesizing fatty acids de novo from glucose.

[Complex knee injuries in football : Management from injury to return to competition].

Background: Knee joint injuries are a regular and serious injury in football, often resulting in a long period of absence for players and are, therefore, a significant disadvantage for clubs. The various structures of the knee joint, such as ligaments, meniscus or cartilage, are exposed to the risk of injury due to different sport-specific situations in football and require different and specific therapeutic approaches for their adequate healing.

Treatment: Both surgical and conservative treatment measures have been well investigated scientifically, especially for knee joint injuries in football, so that a successful and sustainable return to play on field is highly possible.
