Age-related lumbar spinal stenosis frequently diminishes the quality of life. To facilitate a comprehensive evaluation of stenosis severity, diverse classifications have been developed, allowing for study comparisons and improved communication between surgeons and researchers. Although this categorization lacks a direct clinical connection, Schizas’s system seems a straightforward technique for evaluating stenosis. We aimed to assess the independent agreement between different observers (inter-observer) and the same observer at different times (intra-observer) on Schizas’ classification for evaluating stenosis severity. Subsequently, we set out to compare the level of agreement among three progressive levels of expertise in spine surgery.
An independent evaluation of inter and intra-observer agreement took place among junior, senior orthopedic residents and attending spine surgeons. Nineteen observers independently analyzed a collection of ninety lumbar levels from a group of thirty patients. A weighted kappa agreement analysis was conducted.
The overall inter-observer and intra-observer agreement rates were 0.57 (95% confidence interval = 0.52-0.63) and 0.69 (0.55-0.79), respectively. The level of training of observers influenced interobserver agreement, which was 0.53 (0.46-0.60) for junior residents, 0.61 (0.54-0.67) for senior residents, and 0.67 (0.59-0.74) for attendings. Regarding intraobserver agreement, junior staff achieved a score of 0.54 (0.48-0.60), senior staff a score of 0.60 (0.55-0.66), and attending staff a score of 0.66 (0.60-0.72).
The Schizas classification showed a moderate level of agreement between observers, but a substantial degree of agreement within the same observer. The observing surgeons exhibited considerable agreement in their assessments, both inter- and intra-rater. Acceptable communication among trained spinal surgeons resulted from the implemented classification.
According to the Schizas’s classification, the agreement amongst different observers was only moderate, but the agreement within a single observer was substantial. Inter- and intraobserver agreement was notably strong among the surgical team present. The classification structure facilitated acceptable communication amongst trained spine surgeons.
Post-stroke evaluations of hand function, while considering motor performance, often neglect the subtle, yet consequential, impairments in everyday object handling. Efficiently lifting an object demands a prediction of needed forces based on inherent object characteristics (sensorimotor integration), subsequent adjustments to these predictions for unpredictable objects (sensorimotor memory), and the capability to regulate distal fingertip forces, an aspect not usually captured by diagnostic or rehabilitative assessment tools in clinics. The research, presented here, analyzed three components of proficient object manipulation among 60 individuals with chronic, unilateral middle cerebral artery stroke. Age-matched control participants served as a benchmark for performance comparisons, which were further analyzed using linear regressions to predict performance based on clinical scores. Post-stroke participants, in at least one task, demonstrated a lower level of performance compared to the control group. Individuals recovering from stroke demonstrated varying deficits in each task they performed, regardless of the damaged cerebral hemisphere. Against expectation, patients with damage to their right brain hemisphere, directly affecting the active hand, demonstrated an impediment to modulating forces occurring remotely. Patients with right hemisphere damage also exhibited impaired sensorimotor integration, contrasting with their control performance on subsequent lifts, unlike left-hemisphere-damaged individuals. Finally, during sensorimotor memory tasks, neither group of patients surpassed control limits on the initial lifting attempts. Nevertheless, patients with right hemisphere damage exhibited declining performance in subsequent lifts, suggesting their struggle to learn the novel color-mass correlations for the objects. This research demonstrates that patients with unilateral MCA strokes may exhibit deficits in some or all of the components necessary for manipulating hand-held objects, emphasizing that skilled object lifting depends on the integrity of bilateral systems. This information can also be utilized in future studies, potentially improving the efficacy of rehabilitation programs by adapting them to the specific deficits of stroke victims.
Severe motor and sensory impairments are a hallmark of spinal cord injury (SCI), with no effective therapeutic interventions. Spinal cord injury (SCI) is incessantly aggravated by debris (sp) from the damaged spinal cord. Our previous findings, in alignment with other research, pinpoint bone marrow-derived macrophages (BMDMs) as the primary infiltrators targeting the lesion epicenter to clear sp, rather than local microglia. Unfortunately, the infiltrating BMDMs’ pro-inflammatory characteristics are strongly pronounced, thereby compromising wound healing. The protective effects of hydralazine, a potent vasodilator and acrolein scavenger, manifest in a variety of illnesses. Confirmation shows that hydralazine, by scavenging acrolein, promotes motor function and hypersensitivity in SCI rats. Few studies have addressed the consequences of hydralazine on immunomodulation, not to mention its effect on spontaneous pain and emotional response, crucial features observed in clinical settings. The impact of hydralazine on infiltrating bone marrow-derived macrophages (BMDMs) after spinal cord injury (SCI) is presently unknown. Our investigation into the impact of hydralazine on immune cells used BMDMs within a mouse model of spinal cord injury (SCI). We also examined the part played by polarized BMDMs in hydralazine’s influence on neurological recovery after SCI in male mice. Adult male mice underwent compression of their spinal cords at the T10 level. The study’s results revealed that hydralazine, besides improving motor function and treating hypersensitivity, also relieved SCI-induced spontaneous pain and emotional responses, a newly recognized characteristic. Hydralazine effectively prevented the influx of pro-inflammatory bone marrow-derived macrophages (BMDMs) and stimulated the transformation of infiltrated BMDMs into a more reparative phenotype, contributing to various biological processes crucial for spinal cord injury (SCI) pathology, including immune/inflammation response, neurogenesis, lipid metabolism, oxidative stress, fibrosis development, and angiogenesis. The neurological function following spinal cord injury saw a partial recovery, thanks to the action of hydralazine-treated BMDMs, augmented with sp. Hydralazine is determined to affect the immune system, prompting a transformation of pro-inflammatory bone marrow-derived macrophages (BMDMs) into a more restorative phenotype; this action by hydralazine-educated BMDMs is correlated with enhanced neurological function in spinal cord injury (SCI) mice, suggesting the efficacy of combining drugs and cells for treating SCI.
Traumatic Spinal Cord Injuries (SCI) are currently being studied in preclinical in vivo settings, with the implantation of 3D-bioprinted scaffolds as a promising therapeutic avenue. No systematic assessment of the relevant literature has been performed up to this point in time. Consequently, we comprehensively examined the results of utilizing 3D-bioprinted implants in treating spinal cord injury (SCI), drawing upon research performed on animal models.
A comprehensive search of PubMed, Scopus, Web of Science, and Cochrane Library databases was undertaken. In vivo preclinical study designs were not adhered to, or if composed in a language not being English, manuscripts were excluded. To evaluate bias risks, SYRCLE’s instrument was employed. The assessment of the included articles’ quality was conducted using the ARRIVE guidelines. Only a qualitative synthesis of the extracted data was feasible, given the data’s unsuitability for meta-analysis procedures.
Eleven animal studies using the transection SCI rat model were included in the final dataset. Six of the included studies looked at 3D-bioprinted scaffolds which contained stem cells, two examined scaffolds combined with growth factors, and three focused on stand-alone 3D-bioprinted scaffolds. The 3D-bioprinted scaffolds, in every included study, significantly boosted functional scores in SCI rats compared to untreated SCI rats. Functional recovery was observed in conjunction with alterations to the injury site’s histology. Medium risk of bias was observed in seven studies; three studies showed a high risk; and one study displayed a low risk. Furthermore, a portion of the incorporated studies originated from the same research facility. An average quality level, reflected in an overall quality assessment ratio of 0.60, was observed.
Our systematic review reveals that 3D-bioprinted scaffolds may present a practical therapeutic avenue for managing spinal cord injury. Clinical application of 3D-bioprinted scaffolds hinges on further supporting evidence from other experimental SCI models.
