The phytohormone abscisic acid (ABA) as a signaling molecule exists in various types of organisms from early multicellular to animal cells and tissues. It has been demonstrated that ABA has an antinociceptive effect in rodents. The present study was designed to assess the possible role of PKA and phosphorylated ERK (p-ERK) on the antinociceptive effects of intrathecal (i.t.) ABA in male Wistar rats.

Cerebral hydrodynamics complications in shunted patients are due to the malfunction of the system. The objective of this retrospective, single-center, single-arm cohort study is to confirm the safety and performance of Sphera® Duo when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cysts.

The use of opioids to relieve chronic pain has increased during the last decades, but experiences of chronic opioid therapy (COT) (> 90 days) point at risks and loss of beneficial effects. Still, some patients report benefits from opioid medication, such as being able to stay at work. Guidelines for opioid use in chronic pain do not consider the individual experience of COT, including benefits and risks, making the first person perspective an important scientific component to explore. The aim of this study was to investigate the lived experience of managing chronic pain with opioids in a sample who have severe chronic pain but are able to manage their pain sufficiently to remain at work.

While the burden of neurologic illness in developing countries is increasing, less is known about mortality among patients admitted to sub-Saharan African hospitals with neurologic disease. We sought to characterize the rate and patient-level predictors of in-hospital mortality in a Ugandan Neurology ward.cc.

Migraine is a complex neurological disorder with high co-existing morbidity burden. The aim of our study was to examine the overall morbidity and phenotypic diseasome for migraine among people of working age using real world data collected as a part of routine clinical practice.

The authors conducted a study to analyze associations between changes in depression/anxiety before and 12 months after spine surgery, as well as changes in scores using the Patient-Reported Outcomes Measurement Information System (PROMIS) at the same time points.

Stereotactic radiosurgery (SRS) has been used to treat trigeminal neuralgia by targeting the cisternal segment of the trigeminal nerve, which in turn triggers changes in the gasserian ganglion. In the lumbar spine, the dorsal root ganglion (DRG) is responsible for transmitting pain sensitivity and is involved in the pathogenesis of peripheral neuropathic pain. Therefore, radiosurgery to the DRG might improve chronic peripheral pain. This study evaluated the clinical and histological effects of high-dose radiosurgery to the DRG in a rodent model.

Median arcuate ligament syndrome (MALS) is a rarely diagnosed condition resulting from compression of the celiac trunk (CT) by the median arcuate ligament (MAL) of the diaphragm. Ischemia due to reduced blood flow through the CT and/or neuropathic pain resulting from celiac ganglion compression may result in a range of gastrointestinal symptoms, including nausea, postprandial discomfort, and weight loss. However, the mechanism of compression and its anatomical correlates have been incompletely delineated. It has been hypothesized that CT angle of origination may be more acute in individuals with MALS. Here, frequency of anatomical variation in the MAL and CT were assessed in 35 cadaveric subjects (17M/18F), including the vertebral level of origin of CT and superior mesenteric artery (SMA), the distance between CT and MAL and SMA, the angles of origination of CT and SMA, the diameter at the CT base, and MAL/CT overlap. Females exhibited significantly higher rates of inferred MAL/CT overlap than males. Significant correlations were revealed between MAL/CT overlap and angles of origination of the CT and SMA. Vertebral level of origin of the CT in individuals with MAL/CT overlap was not significantly more superior than in those without. This study also revealed a significant relationship between MAL/CT overlap and angle of origination of the CT, which has clinical implications for understanding the anatomy associated with MALS.

Recent studies have shown that cattle practitioners are concerned about painful conditions and procedures. An understanding of the attitudes toward pain is fundamental to encourage the use of pain relief in cattle. The goal of this study was to investigate the factors that influence Brazilian professionals toward the use of pain mitigation in cattle, primarily during castration and horn removal (e.g. dehorning, disbudding). To reach this objective, an online survey was conducted with veterinarians and animal scientists. The analysis was based on descriptive statistics, chi-squares tests, Fisher exact tests, and Mann-Whitney U tests. The final sample was composed of 147 respondents. Results of descriptive statistics showed that the use of medicine before a painful procedure (i.e., anesthetic, anti-inflammatory, or sedative-analgesic), was higher for adult cattle than for suckled and newborn calves. In newborn calves, those respondents who were more likely to use pain relief agreed with the statements that i) there is missing information about pain control during castration and ii) defensive movements shown by an animal during or after a procedure to justify pain mitigation in horn removal. The primary reasons for choosing a medicine were similar for both procedures: cost, anti-inflammatory effect, analgesic potency, duration of analgesic effect, duration of sedative effect, and route of administration. There was no difference in professional's decade of birth and pain mitigation use. These results may be useful to decide how to optimize the use of drugs by veterinary and animal science professions, and continuing education should help to increase pain mitigation usage.
