Swelling of Multilayered Calcium Alginate Microspheres for Drug-Loaded Dressing Induced Rapid Lidocaine Release for Better Pain Control.

The development of effective drug-loaded dressings has been considered a hot research topic for biomedical therapeutics, including the use of botanical compounds. For wound healing, adequate dressings can provide a good microenvironment for drug release, such as lidocaine. Biological macromolecular materials such as alginate show excellent properties in wound management. This study involves the preparation and evaluation of biocompatible multilayered-structure microspheres composed of chitosan, porous gelatin, and calcium alginate microspheres. The multilayered structure microspheres were named chitosan@ porous gelatin@ calcium alginate microspheres (CPAMs) and the drugs were rapidly released by the volume expansion of the calcium alginate microspheres. The release curve revealed that the peak release of lidocaine from CPAMs was reached within 18[Formula: see text]min. After 21[Formula: see text]min, the remaining lidocaine was then slowly released, and the active drug release was converted to a passive drug release phase. The initial release effect of lidocaine was much better than that reported in the published studies. Additionally, blood coagulation experiments showed that CPAMs coagulated blood in 60[Formula: see text]s, and the blood liquidity of the CPAMs group was worse than that of the woundplast group. Therefore, the coagulation characteristics of CPAMs were superior to the commonly used woundplast containing lidocaine healing gel. These study outcomes indicated that the CPAMs acted as fast-release dressings for faster pain control and better coagulation properties.

A Narrative Review of the Impact of Extracorporeal Membrane Oxygenation on the Pharmacokinetics and Pharmacodynamics of Critical Care Therapies.

Extracorporeal membrane oxygenation (ECMO) utilization is increasing on a global scale, and despite technological advances, minimal standardized approaches to pharmacotherapeutic management exist. This objective was to create a comprehensive review for medication dosing in ECMO based on the most current evidence.

Studies on the mechanism of energy metabolism via AMPK/PGC-1α signaling pathway induced by compatibility of Ligusticum chuanxiong Hort and Gastrodia.

AMP-activated protein kinase (AMPK) regulates overall energy consumption and energy intake through cytokines. Ligusticum striatum DC (CX) combined with Gastrodia elata Blume (TM) has been used for migraine treatment for millennia. When used alone in clinical practice, CX causes symptoms of thirst, irritability, and yellow urine and has influenced the levels of cytokines such as AMP that activate the AMPK pathway of energy metabolism. However, relationships between this compatibility prescription, integral biological energy metabolism, and the AMPK pathway remain unclear. Studies were performed by treating normal rats with physiological saline, CX extract, CX coupled TM extract, and TM extracts separately for 4 weeks. Food intake, water intake, urine output, stool output, and body weight were monitored once a week by the metabolic cage method. Values of FBG, BUN, TP, TC and TG in blood samples were detected approaching the whole blood automatic detector from 1 to 4 weeks. Na -K -ATPase, Ca -Mg -ATPase, cAMP, and cGMP activity were determined by the enzyme-linked immunosorbent assay (ELISA); the biological samples that were obtained at 1, 2, 3, and 4 weeks after drug administration were tested by GC-TOF-MS. Then real-time PCR and Western Blot were applied to detect changes in expression of some substances involved in energy metabolism. The results demonstrated that administering CX alone increased energy input, mobility, and respiratory exchange ratio, accelerated energy consumption, and caused inflammatory infiltration in the liver. CX coupled with TM led to lower energy metabolism and liver damage in comparison with CX used alone. Moreover, CX-treated rats harbored higher levels of differential metabolites (including pyrophosphate, oxaloacetic acid, and galactinol). Glycerophospholipid metabolism and the citrate cycle are closely related to the differential metabolites above. In addition, CX-induced unbalanced energy metabolism depends on cAMP activation mediated by the AMPK/PGC-1α pathway in rats. Our findings suggest that CX-induced energy metabolism imbalance was corrected after coupling with TM by mediating the AMPK/PGC-1α pathway.

A case of VIPoma.

This case report addresses the management of a pregnant woman in the peripartum period with a VIPoma. This rare and highly malignant neuroendocrine tumour secretes vasoactive intestinal peptide (VIP), a substance that may cause potentially life-threatening disruption to physiology. A 36-year-old woman presented for induction of labour with a three-year history of chronic diarrhoea, hypophosphataemia, palpitations and skin flushing. Raised VIP levels indicated presence of a VIPoma, however despite extensive investigation prior to pregnancy by neuroendocrine specialists, the tumour location remained unidentified. The patient delivered a healthy boy with the aid of forceps in theatre following an epidural top-up. Key features of management were a multidisciplinary approach, avoidance of triggers for VIP secretion, strict management of electrolytes and avoidance of severe changes in sympathetic tone during labour with epidural analgesia.

BAY-117082-driven NLRP3 inflammasome inhibition resolves nitro-glycerine (NTG) neuronal damage in in vivo model of migraine.

Migraine is a common neuronal disorder characterized by recurrent episodes of headache associated with a higher prevalence in women than men. Several risk factors have been associated with migraine disease as genetic factors, gender, and age. Although understanding migraine pathophysiology is improved, it has been reported that NOD-like receptor protein 3 (NLRP3) inflammasome pathway overactivation can contribute to migraine progression. Therefore, the aim of this study was to investigate the effect of BAY-117082, an NLRP3 inflammasome inhibitor, in a mouse model of nitroglycerin (NTG)-induced migraine. The in vivo model of migraine was induced by intraperitoneal (i.p) injection of NTG (dose of 10 mg/kg). Mice were treated intraperitoneally with BAY-117082 at doses of 1 mg/kg, 5 mg/kg, and 10 mg/kg, 5 min following NTG injection. After 4 h of NTG injection, the whole brain tissue with the rostral spinal cord were collected and used to perform further analysis. Our results demonstrated that BAY-117082 treatments (5 mg/kg and 10 mg/kg) reduced pain attacks, hyperalgesia and photophobia more in female mice NTG-induced. Moreover, the treatment with BAY-117082 significantly reduced histological damage in the trigeminal nerve nucleus in female mice accordingly to significantly decreased in NLRP3 complex components expression levels such as ASC, IL-1β, IL-18, caspase-1 and TNF-α levels. Additionally, the treatment with BAY-117082 at both higher doses significantly modulated CREB/Erk/Akt pathways strictly correlated to the expression of neurotrophic factors. Taken together, obtained results confer new insight into the role of the NLRP3 inflammasome pathway in migraine pathogenesis, suggesting that BAY-117082 could be considered a novel strategy therapeutics for migraine treatment despite unconventional drug use.

Prevalence and predictors of anxiety disorder courses in the Canadian Armed Forces.

Few studies have examined the longitudinal courses of anxiety disorders in military members. This study examined the prevalence and predictors of courses of any anxiety disorder in members and veterans of the Canadian Armed Forces, including no lifetime, remitted, new onset, and persistent/recurrent anxiety disorder. The 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey is a 16-year follow-up of n = 2941 participants from the Canadian Community Health Survey: Canadian Forces Supplement in 2002. Diagnoses of any DSM-IV anxiety disorder (i.e., generalized anxiety, social anxiety, and/or panic disorder) in 2002 and 2018 were used to create four anxiety course groups. A large proportion of the sample (36.3 %; new onset = 24.6 %, remitting = 6.9 %, and persistent/recurrent = 4.8 %) met criteria for an anxiety disorder during one or both time points. Factors at baseline and/or between 2002 and 2018, including income, education, military rank, comorbidity of PTSD or depression, deployment history, and traumatic events, were positively associated with most anxiety courses relative to no anxiety in analyses. Targeted interventions are needed to help mitigate anxiety disorders among this population. Social support and active coping were protective factors for most anxiety courses and may need to be incorporated into targeted interventions.
