During the COVID-19 pandemic, lung ultrasound (LUS) has been widely used since it can be performed at the patient's bedside, does not produce ionizing radiation, and is sufficiently accurate. The LUS score allows for quantifying lung involvement; however, its clinical prognostic role is still controversial.

Intracerebral hemorrhage (ICH) is devastating among stroke types with high mortality. To date, not a single therapeutic intervention has been successful. Cofilin plays a critical role in inflammation and cell death. In the current study, we embarked on designing and synthesizing a first-in-class small-molecule inhibitor of cofilin to target secondary complications of ICH, mainly neuroinflammation. A series of compounds were synthesized, and two lead compounds SZ-3 and SK-1-32 were selected for further studies. Neuronal and microglial viabilities were assessed by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay using neuroblastoma (SHSY-5Y) and human microglial (HMC-3) cell lines, respectively. Lipopolysaccharide (LPS)-induced inflammation in HMC-3 cells was used for neurotoxicity assay. Other assays include nitric oxide (NO) by Griess reagent, cofilin inhibition by F-actin depolymerization, migration by scratch wound assay, tumor necrosis factor (TNF-α) by enzyme-linked immunosorbent assay (ELISA), protease-activated receptor-1 (PAR-1) by immunocytochemistry and Western blotting (WB), and protein expression levels of several proteins by WB. SK-1-32 increased neuronal/microglial survival, reduced NO, and prevented neurotoxicity. However, SZ-3 showed no effect on neuronal/microglial survival but prevented microglia from LPS-induced inflammation by decreasing NO and preventing neurotoxicity. Therefore, we selected SZ-3 for further molecular studies, as it showed potent anti-inflammatory activities. SZ-3 decreased cofilin severing activity, and its treatment of LPS-activated HMC-3 cells attenuated microglial activation and suppressed migration and proliferation. HMC-3 cells subjected to thrombin, as an in vitro model for hemorrhagic stroke, and treated with SZ-3 after 3 h showed significantly decreased NO and TNF-α, significantly increased protein expression of phosphocofilin, and decreased PAR-1. In addition, SZ-3-treated SHSY-5Y showed a significant increase in cell viability by significantly reducing nuclear factor-κ B (NF-κB), caspase-3, and high-temperature requirement (HtrA2). Together, our results support the novel idea of targeting cofilin to counter neuroinflammation during secondary injury following ICH.

Preemptive injection of local anesthetics can prevent postoperative pain at the incision site, but the analgesic effect is insufficient and is maintained only for a relatively short period of time. Diprospan is a combination of quick-acting betamethasone sodium phosphate and long-acting betamethasone dipropionate. Whether Diprospan as an adjuvant to local anesthetic can achieve postcraniotomy pain relief has not been studied yet.

Buprenorphine possesses many unique attributes that make it a practical agent for adults and adolescents with opioid use disorder (OUD) and/or acute or chronic pain. Sublingual buprenorphine has been the standard of care for treating OUD, but its use in pain management is not as clearly defined. Current practice guidelines recommend a period of mild to moderate withdrawal from opioids before transitioning to buprenorphine due to its ability to displace full agonists from the μ-opioid receptor. However, this strategy can lead to negative physical and psychological outcomes for patients. Novel initiation strategies suggest that concomitant administration of small doses of buprenorphine with opioids can avoid the unwanted withdrawal associated with buprenorphine initiation. We aim to systematically review the buprenorphine initiation strategies that have emerged in the last decade.

Median nerve block can provide excellent analgesia during open surgery for trigger thumb in children. However, no data on the 90% minimum effective volume (MEV) and concentration (MEC) of ropivacaine for ultrasound-guided median nerve block in pediatric patients have been reported.

To examine the prevalence of sleep disturbances, quantified by the Pittsburgh Sleep Quality Index (PSQI), in patients with psoriatic arthritis (PsA), psoriasis (PsO) and healthy controls (HCs), explore associations between PSQI and clinical and patient-reported outcomes, and evaluate the effect of treatment on PSQI.

Laboratory data suggest that insufficient circulating levels of the anti-inflammatory cytokine interleukin-1 receptor antagonist (IL-1ra) are associated with intrapartum inflammation and epidural-related maternal fever, both of which increase the rate of obstetric interventions and antibiotic use during labour. Genetic polymorphisms strongly influence IL-1ra levels in the general population. We aim to examine the association between IL-1ra polymorphisms and epidural-related maternal fever using Mendelian randomization analysis.

A multidisciplinary approach is recommended for patients with complex chronic pain (CP). Many multidisciplinary pain treatment facilities (MTPFs) use patient exclusion criteria but little is known about their characteristics. The objective of this study was to describe the frequency and characteristics of exclusion criteria in public Canadian MTPFs.

In the present meta-analysis, the efficacy and safety of perampanel (PER) for the treatment of adolescents with epilepsy were assessed.

Inflammatory bowel disease (IBD) is a chronic disease whose etiology is not yet fully understood, and their course is characterized by periods of exacerbation and remission. In quite a few cases, actual disease remission may also accompany with inflammatory bowel disease (IBS)-like symptoms such as abdominal pain, bloating, flatulence, and diarrhea, may greatly impact quality of life. An army of strong evidence to support the FODMAPs diet (LFD) compounds as an effective dietary approach to IBS treatment. However, there is no significant evidence showing the effectiveness of LFD in treating quiescent IBD and its side effects; this lack of evidence is also an important factor hindering its promotion in the treatment of IBD and its complications. Therefore, this systematic review and meta-analysis will evaluate the efficacy and safety of LFD in the treatment of quiescent IBD patients with IBS-like symptoms.
