Lessons Learned While Designing A Next-Generation Firefighting Hel- met: Preliminary Data

In this study, we evaluated the effects of weight and profile (center of gravity location) of three different most widely used firefighting helmets on the head-neck kinematics, positional instability, visual range,and comfort. we compared three different firefighter helmets: a traditional-look (with-brim) helmet (58 oz),a jet-style helmet (62.25 oz), and the jet-style helmet with lighting and communication systems (70.85 oz); all are large.. Since our preliminary investigation showed promising results for the jet-style helmet type, a thorough systematic analysis on a large sample is warranted. Some legitimate concerns that we observed in the preliminary study include: 1) excessive helmet weight caused neck hyper-flexion and imbalanced lateral bending, 2) the CoG of the helmet system lies away from the mid-sagittal plane, and 3) the weight and the displaced CoG poses the threat of an increased risk of cervical spinal disc loading, which can result in disc herniation and degenerated disc.

Barricaid Spinal Implant Device

Horizon Scan reports provide brief summaries of information regarding new and emerging health technologies. These technologies are identified through the CADTH Horizon Scanning Service as topics of potential interest to health care decision-makers in Canada. This Horizon Scan summarizes the available information regarding an emerging technology, Barricaid — a spinal implant device for those at risk of recurrent spinal disc herniation.

Does Needle Design Affect the Regenerative Potential of Bone Marrow Aspirate? An In Vitro Study

While autologous bone is still the gold standard for treatment of bone defects, its availability is limited. Sufficient numbers of mesenchymal stroma cells (MSC) may be an alternative. Small volumes of bone marrow aspirate (BMA) were harvested with two different needle systems comparing the yield and regenerative potency of the MSCs. BMA (10 mL) was aspirated from the posterior iliac crest of 12 patients with degenerative spinal disc disease using both needle systems in each patient: the Jamshidi needle (JAM) and on the contralateral side the Marrow Cellution® Needle (AMC). Number of mononuclear cells (MNCs) and regeneration capacity (colony-forming unit/CFU) were determined. MSCs were characterized for surface markers and their differentiation into trilineages. There was no significant difference between the two harvesting needles regarding the quantity of MNCs in BMA: 5.2 ± 1.8 × 109 MNC/mL for AMC vs. 4.8 ± 2.5 × 109 MNC/mL for JAM, p = 0.182. The quantity of CFUs per ml BMA was similar for both groups: 3717 ± 5556 for AMC and 4305 ± 5507 for JAM (p = 0.695). The potency of MSCs expressed as colony-forming potential per 106 MNC resulted in 0.98 ± 1.51 for AMC and 1.00 ± 0.96 for JAM (p = 0.666). Regardless of the needle design, 10 mL bone marrow aspirate contains a sufficient number of about 40,000 MSCs that can be used to enhance bone healing.

RESULTS OF PHYSICAL THERAPY REHABILITATION IN PATIENTS WITH DISEASE AS LUMBER SPINAL DISC HERNIATION

The researchon 60 patients with lumber spinal disc herniation treated with physical therapy- rehabilitation methods at the hospital 198. The result as follows: Very good 30%, good 60%, average 10%. This is simple, non- pharmacological, conservative medical treatment that is effective for mild and moderate lumbar spinal disc herniation.
