Case Reports
A 67-Year-Old Male Patient With COVID-19 With Worsening Respiratory Function and Acute Kidney Failure.
A 67-year-old obese man (BMI 38.0) with type 2 diabetes mellitus (DM), chronic atrial fibrillation, and chronic lymphocytic leukemia stage II, stable for 8 years after chemotherapy, and a history of smoking presented to the ED with progressive dyspnea and fever due to SARS-CoV-2 infection. He was admitted to a general ward and treated with dexamethasone (6 mg IV once daily) and oxygen. ⋯ On day 9 of ICU admission, voriconazole treatment was initiated after tracheal white plaques at bronchoscopy, suggestive of invasive Aspergillus tracheobronchitis, were noticed. However, his medical situation dramatically deteriorated.

Abdominal pain is a key symptom of inflammatory bowel disease and irritable bowel syndrome, for which there are inadequate therapeutic options. We tested whether olorinab-a highly selective, full agonist of the cannabinoid receptor 2 (CB2)-reduced visceral hypersensitivity in models of colitis and chronic visceral hypersensitivity (CVH). In rodents, colitis was induced by intrarectal administration of nitrobenzene sulfonic acid derivatives. ⋯ By contrast, olorinab did not alter VMRs nor nociceptor responsiveness in control animals. Cannabinoid receptor 2 mRNA was detected in colonic tissue, particularly within epithelial cells, and dorsal root ganglia, with no significant differences between healthy, colitis, and CVH states. These results demonstrate that olorinab reduces visceral hypersensitivity through CB2 agonism in animal models, suggesting that olorinab may provide a novel therapy for inflammatory bowel disease- and irritable bowel syndrome-associated abdominal pain.

Chronic pain can be difficult to predict and a challenge to treat. Biomarkers for chronic pain signal an opportunity for advancements in both management and prevention, and through their research and development offer new insights into the complex processes at play. ⋯ While some headway has been made that offers efficiencies in patient selection, it is unlikely that a single test will encompass the variety of chronic pain phenotypes. We offer some insights for the near future in biomarker development and areas of continued unmet need.

Chronic opioid therapy (COT) has been used to treat many chronic pain conditions even with poor evidence for its long-term effectiveness. Medical cannabis has emerged with certain pain-relieving properties, which has led to questions as to its' potential application, especially in relation to its effect on opioid use. ⋯ Presenting medical cannabis to chronic pain patients on COT should be done in the context of a patient choice between medical cannabis WITH decrement of COT or continued current dose of COT in order to maximize effectiveness in opioid reduction as well as to limit polypharmacy concerns regarding medical cannabis. Allowing for a temporary short-term period where patients may trial medical cannabis, while concomitantly gradually weaning their COT, is also essential in determining medical cannabis' individual effectiveness for that patient's specific type of chronic pain, which should serve to maximize long-term opioid reduction results and hence decrease opioid-related overdose deaths.

Analysis of Potential Hub Genes for Neuropathic Pain Based on Differential Expression in Rat Models.
Neuropathic pain (NP) is a type of intractable chronic pain with complicated etiology. The exact molecular mechanism underlying NP remains unclear. In this study, we searched for molecular biomarkers of NP. ⋯ The results of this study form a basis for further research into the mechanism of NP development and are expected to aid in the development of novel therapeutic strategies.
