This cross-sectional study assessed the associations between respiratory symptoms and plasma vitamin D and measures of body fat in individuals with chronic SCI. The study found that increased body fat...
KEY FINDING: Increased body fat (android, gynoid, trunk, or total body fat) was associated with increased odds ratios for any wheeze and suggestive associations with persistent wheeze, but not with chronic cough or phlegm.

This study demonstrates that spinal PKC activation elicits pMF, an effect prevented by pretreatment with two PKC inhibitors that differ in their mechanism of action and isoform specificity: BIS and NP...
KEY FINDING: Spinal PKC activation via intrathecal PMA elicits pMF.

The study examined the impact of disuse and retraining on lower limb muscle power in young and older adults. Disuse led to a significant decrease in MEP in older adults, while retraining was insuffici...
KEY FINDING: Disuse significantly decreased maximal explosive power (MEP) in older adults but not significantly in young adults.

This article reviews the impact of spinal cord injury (SCI) on sexual function, covering the basic anatomy and physiology of sexual responses, the pathophysiology of sexual dysfunction following SCI, ...
KEY FINDING: Peripheral nerves in the pelvis are regulated by cerebral control, and SCI can disrupt this control, impacting both psychological and reflex responses for genital arousal, ejaculation, and orgasm.

Spinal cord injury can lead to alterations in cardiovascular autonomic function, resulting in low resting blood pressure, orthostatic hypotension, and autonomic dysreflexia. The mechanisms behind thes...
KEY FINDING: Individuals with SCI at or above the T6 neurologic level are at increased risk of AD during sexual stimulation. This risk increases with higher and more complete injuries.

The study investigates the specific cervical spinal cells expressing A2A receptors responsible for phrenic motor facilitation (pMF). The researchers used siRNA injections to knock down A2A receptors i...
KEY FINDING: A2A receptors are highly expressed in motor neurons (including phrenic motor neurons) versus other cell types in the cervical spinal cord.
BioMed Research International, 2017 • December 27, 2017
This study investigated the pathological characteristics and stiffness of the gastrocnemius muscle (GM) in a rat model of spinal cord injury (SCI). The researchers used shear wave sonoelastography to ...
KEY FINDING: GM weights were decreased in the SCI model group compared to the control group, indicating muscle atrophy.

This study evaluated the accuracy of DXA in quantifying trunk lean mass compared to MRI in men with SCI. The results showed that DXA overestimated trunk lean mass when compared to MRI. The study also ...
KEY FINDING: DXA overestimated trunk lean mass compared to MRI measurements. Trunk LM-DXA (24 ± 3.3 kg) and android LM-DXA (3.6 ± 0.7 kg) overestimated (P < 0.0001) trunk LM-MRI (1.7 ± 0.5 kg).
Spinal Cord, 2018 • October 1, 2018
This study evaluated the reproducibility of total and regional DXA-derived body composition values in individuals with spinal cord injury (SCI). The study assessed both short-term (same day) and long-...
KEY FINDING: Short-term precision: The RMS-CV% for each region did not exceed 5.6%, 2.7%, 3.8%, 6.5%, 5.8% and 2.3% for arms, legs, trunk, android and gynoid regions and total body mass, respectively.

The study examined the effects of isoflurane anesthesia on spinal cord neurovascular coupling in decerebrated rats during sciatic nerve stimulation. Results indicated that isoflurane did not significa...
KEY FINDING: Isoflurane anesthesia (1.2%) did not significantly alter LFP amplitude (p = 0.53) in the spinal cord of decerebrated rats.
