“…Currently, there are different opinions regarding the effect of running on articular cartilage of the knee. Short interval and regular running seems to have a protective effect on articular cartilage [1][2][3][4]. Similarly, several studies concluded that running a marathon does not increase pathology or osteoarthritis (OA) in the knee joint [5][6][7][8][9][10], and some data indicate a protective effect of long-distance running [11,12].…”

Femoropatellar Joint Reaction Detected During a 4486 KM Ultramarathon with Mobile MRI

Almost nothing is known about the condition of the knee joints of multistage ultra-marathon (MSUM) runner. This is first image-based investigation of the femoropatellar joint (FPJ) using a mobile 1.5T MRI accompanying the MSUM TransEurope Foot-Race (TEFR) 64 stages over 4486 km. Twenty-two (20 male) subjects got a knee MRI-protocol at defined measurement intervals during TEFR: T2*-mapping (FLASH T2*-GRE), TIRM, and fat saturated PD -sequence. In the FPJ 12 different regions were evaluated regarding cartilage T2* and thickness changes and cartilage lesions in course of TEFR and a test on possible compounding factors (running burden, BMI, age) was done if being appropriate. No significant changes in cartilage thickness- and T2*-values were found during TEFR. In 8 runners, at least one single cartilage lesion (Grade 2–3) was found at baseline, but no significant race-related adjacent T2*-changes or progress of the defects could be detected. Analyses on compounding factors were negative. In knees with MPP (5) significantly lower adjacent T2*-values were found. The extreme running burden of a MSUM seems not to have a relevant negative influence on the FPJ tissues, even if cartilage lesions are present.

“…The increase in movement due to the dog is an important prophylaxis against cardiovascular diseases [49], which is a frequent reason for hospitalizations [50]. Movement also prevents diabetes, intestinal cancer and age-related falls [51] and even has a positive effect on arthrosis [52].…”

In a rural area near Munich, 52 persons aged 65 years and older were interviewed in person about health and social life circumstances. Findings: Dog owners take significantly longer walks than people who do not own dogs, averaging more than 120 minutes daily (p < 0.0001). On average, people who do not own a dog walked 38 minutes, cat owners 17 minutes. 94% of the dog owners were active daily compared to 14% of those who do not own a dog. Dog owners go to the doctor on average 5.3 times per year, people who do not own a dog 7.8 times. There was no difference between the two groups in regard to the use of medication. 80% would not move to a residential home for the elderly because of the dog, and 87% would want to take the dog along. 50% of the dog owners and 41% of those who do not own a dog had on average more than 3 contacts with other people, 6% of the dog owners and 23% of those who do not own a dog had less than one contact per day. 19% of the dog owners and 36% of those who do not own a dog would describe themselves as reserved in dealings with people. 71% stated that the dog had been very useful to help them overcome the loss of a person close to them. The W-5 [Wellbeing Five score] for dog owners was an average value of 75%, for those who did not own a dog 71%. Depression was uniformly distributed in both groups. The BMIs in both groups were similar. There was no correlation to the length of the daily walk.

In the last few decades Additive Manufacturing has advanced and is becoming important for biomedical applications. In this study we look at a variety of biomedical devices including, bone implants, tooth implants, osteochondral tissue repair patches, general tissue repair patches, nerve guidance conduits (NGCs) and coronary artery stents to which fused deposition modelling (FDM) can be applied. We have proposed CAD designs for these devices and employed a cost-effective 3D printer to fabricate proof-of-concept prototypes. We highlight issues with current CAD design and slicing and suggest optimisations of more complex designs targeted towards biomedical applications. We demonstrate the ability to print patient specific implants from real CT scans and reconstruct missing structures by means of mirroring and mesh mixing. A blend of Polyhydroxyalkanoates (PHAs), a family of biocompatible and bioresorbable natural polymers and Poly(L-lactic acid) (PLLA), a known bioresorbable medical polymer is used. Our characterisation of the PLA/PHA filament suggest that its tensile properties might be useful to applications such as stents, NGCs, and bone scaffolds. In addition to this, the proof-of-concept work for other applications shows that FDM is very useful for a large variety of other soft tissue applications, however other more elastomeric MCL-PHAs need to be used.
