Effectiveness of Epiduroscopy for Patients with Failed Back Surgery Syndrome: a Systematic Review and Meta-analysis.

Low back or leg pain in patients suffering from failed back surgery syndrome (FBSS) is often severe, having a major impact on functionality and quality of life. Despite conservative and surgical treatments, pain can be persistent. An alternative treatment option is epiduroscopy: a minimally invasive procedure based on mechanical adhesiolysis of epidural fibrosis. Since epidural fibrosis is speculated to be a major contributor in the pathophysiologic process of FBSS, this review evaluates the effectiveness of epiduroscopy in FBSS patients.

The problem of uncertain adherence to study interventions: what can we conclude?

Intrahepatic cholestasis of pregnancy (ICP), the most common liver disease in pregnancy, is characterised by elevated bile acid concentrations and maternal pruritus, and has been associated with increased rates of stillbirth, preterm birth, and neonatal unit admission. Fetal complications have been associated with rising serum bile acids (Glantz et al, Hepatology 2004;40:467- 474) and, according to a recent individual patient data meta-analysis (Ovadia et al, The Lancet 2019;393:899-909), the risk of stillbirth increased in women with serum bile acid concentrations of 100 μmol/l or more.

Chronic Treatment With Hydrogen Sulfide Donor GYY4137 Mitigates Microglial and Astrocyte Activation in the Spinal Cord of Streptozotocin-Induced Diabetic Rats.

Long-term diabetic patients suffer immensely from diabetic neuropathy. This study was designed to investigate the effects of hydrogen sulfide (H2S) on peripheral neuropathy, activation of microglia, astrocytes, and the cascade secretion of proinflammatory cytokines in the streptozotocin (STZ)-induced peripheral diabetic neuropathy rat model. STZ-induced diabetic rats were treated with the water-soluble, slow-releasing H2S donor GYY4137 (50 mg/kg; i.p.) daily for 4 weeks. Antiallodynic/antihyperalgesic activities were evaluated using different tests and histopathological changes and the expression of proinflammatory cytokines in the spinal cord were examined. GYY4137 treatment produced neuroprotective effects in the spinal cord of diabetic animals and modulated their sensory deficits. The treatment decreased allodynia (p < 0.05) and mechanical hyperalgesia (p < 0.01) and restored thermal hyperalgesia (p < 0.001) compared with diabetic rats. The treatment decreased the microglial response and increased astrocyte counts in spinal cord gray and white matter compared with untreated diabetic rats. Proinflammatory cytokines were reduced in the treated group compared with diabetic rats. These results suggest that H2S has a potentially ameliorative effect on the neuropathic pain through the control of astrocyte activation and microglia-mediated inflammation, which may be considered as a possible treatment of peripheral nerve hypersensitivity in diabetic patients.

Managing toxicities of Bruton tyrosine kinase inhibitors.

Inhibition of Bruton's tyrosine kinase (BTK) has revolutionized the treatment landscape for patients with chronic lymphocytic leukemia (CLL). By targeting this critical kinase in proximal B-cell receptor signaling, BTK inhibitors (BTKis) impair cell proliferation, migration, and activation of NF-κB. Clinically, because indefinite inhibition is a mainstay of therapy, there is an extended period of exposure in which adverse effects can develop. Given the impressive efficacy and activity of BTKis in the treatment of patients with CLL, appropriate management of treatment-emergent adverse events (AEs) is of paramount importance. Here we review the BTKi landscape and present the available toxicity and safety data for each agent. The long-term toxicity profile of ibrutinib, a first-in-class inhibitor, is well characterized and includes a clinically significant incidence of cardiac arrhythmias, bleeding, infection, diarrhea, arthralgias, and hypertension. Acalabrutinib, the initial second-generation BTKi to earn approval from the US Food and Drug Administration, demonstrates improved kinase selectivity for BTK, with commonly observed adverse reactions including infection, headache, and diarrhea. Mediated by both on-target inhibition of BTK and variable off-target inhibition of other kinases including interleukin-2-inducible T-cell kinase (ITK), tyrosine-protein kinase (TEC), and endothelial growth factor receptor (EGFR), the toxicity profile of BTKis is closely linked to their pattern of kinase binding. Other emerging BTKis include second-generation agents with variable degrees of kinase selectivity and third-generation agents that exhibit reversible noncovalent binding to BTK. We also highlight critical considerations for the prevention and monitoring of AEs and offer practical management strategies for treatment-emergent toxicities.

Role of venous stenting for venous thromboembolism.

Endovenous stenting has emerged as the method of choice to treat iliofemoral venous outflow obstruction. It is used in patients with established postthrombotic syndrome (PTS) after previous deep vein thrombosis (DVT) to reduce symptoms of chronic pain and swelling and to aid ulcer healing in severe cases. Venous stenting is used to alleviate symptoms of obstruction in patients presenting with acute DVT, with the aim of preventing development of PTS. There is a low risk of morbidity and mortality associated with the use of endovenous stenting, and although significant advances have been made, particularly improvements in stent design for use in the venous circulation, data are lacking on beneficial long-term outcomes. Unmet research needs include optimal patient selection, anticoagulant choice and duration, best practice for postoperative surveillance, and use of validated assessment tools to measure outcomes. In this article, I address the potential benefits, as well as the challenges, of endovenous stenting.

Synthesis and Biological Characterization of Cyclic Disulfide-Containing Peptide Analogs of the Multifunctional Opioid/Neuropeptide FF Receptor Agonists That Produce Long-Lasting and Nontolerant Antinociception.

In a previously described chimeric peptide, we reported that the multifunctional opioid/neuropeptide FF (NPFF) receptor agonist (BN-9) produced antinociception for 1.5 h after supraspinal administration. Herein, four cyclic disulfide analogs containing l- and/or d-type cysteine at positions 2 and 5 were synthesized. The cyclized analogs and their linear counterparts behaved as multifunctional agonists at both opioid and NPFF receptors and produced potent analgesia without tolerance development. In comparison to , cyclized peptide exhibited sevenfold more potent μ-opioid receptor agonistic activity . Interestingly, the cyclized analog possessed an improved stability in the brain and an increased blood-brain barrier permeability compared to the parent peptide and produced more potent analgesia after supraspinal or subcutaneous administration with improved duration of action of 4 h. In addition, antinociceptive tolerance of analog was greatly reduced after subcutaneous injection compared to fentanyl, as was the rewarding effect, withdrawal reaction, and gastrointestinal inhibition.

Recommendations to Medical Mission Trip Teams: A Retrospective Study of an Annual Medical Student-Run Mission Trip to Jarabacoa, Dominican Republic.

Introduction There are more than 6,000 international medical mission trips that are conducted annually by United States medical teams. Successfully planning a medical mission trip relies on careful preparation. The objective of this study is to elucidate common chief concerns, diagnoses, and prescription patterns so that medical mission trip teams can effectively prepare for future medical mission trips in Jarabacoa, Dominican Republic, or similar international sites. Methods A retrospective chart review of 940 patient charts was conducted from two University of South Florida Latino Medical Student Association medical mission trips to Jarabacoa, Dominican Republic (DR) that took place during October 2017 and 2018. A coding system was utilized to categorize the data. The most common chief concerns, diagnoses, and medications prescribed were revealed. Findings were stratified further by age (<18 vs ≥18 years old) and sex. Results Our study reveals that 68.6% (n=597/870) of the patients were female and 59.2% (n=161/870) of males were under 18. The most common chief concerns were "cold/flu" (33.2%,n=289/870), gastrointestinal problems (20.3%, n=177/870), headache (20.0%, n=174/870), and musculoskeletal problems (12.0%, n=104/870). The most common diagnoses were viral syndrome (25.4%, n=221/870), presumed parasitic infection (16.9%, n=147/870), hypertension (12.6%, n=110/870), headache (10.6%, n=92/870), and musculoskeletal disorder (8.5%, n=74/870). The most frequently prescribed medications were acetaminophen (18.3%, n=291/1,587), albendazole (15.2%, n=241/1,587), nonsteroidal anti-inflammatory drugs (NSAIDs) (10.5%, n=166/1,587), antihistamines (6.1%, n=97/1,587), and antibiotics (5.9%, n=93/1,587). Conclusions Our study reveals potential areas for improvement of an annual, medical student-run medical mission trip to Jarabacoa, DR. Dedicated efforts should be made to address long-term management of chronic conditions identified or treated on medical mission trips. Community partnerships should be established to facilitate this. We hope this will encourage other medical mission trip teams to analyze their data in order to be more prepared for their trips.
