Postoperative pain management is an essential module for perioperative care, especially for enhanced recovery after surgery programs. Continuous wound infiltration (CWI) with local anesthetic may be a promising postoperative analgesic strategy. However, its analgesic efficacy and safety remain debatable.

Embase and PubMed databases were systematically searched for relevant randomized controlled trials (RCTs). RCTs assessing the analgesic efficacy and safety of CWI with local anesthetic for postoperative analgesia were selected. The outcomes contained pain scores during rest and mobilization, total opioid consumption, time to the first request of rescue analgesia, length of hospital stay, satisfaction with analgesia, time to return of bowel function, postoperative nausea and vomiting, total complication, wound infection, hypotension, and pruritus. The weighted mean difference and risk ratio were used to pool continuous and dichotomous variables, respectively.

A total of 121 RCTs were included. CWI with lery programs for these surgeries.

CWI with local anesthetic is an effective postoperative analgesic strategy with good safety profiles in laparotomy and sternotomy surgery, and thus CWI with local anesthetic may be a promising analgesic option enhancing recovery after surgery programs for these surgeries.Botulinum neurotoxin (BoNT) is a neurotoxin produced by Clostridium botulinum in an anaerobic environment. BoNT is the most toxic protein among bacteria, animals, plants, and chemical substances reported to date. BoNTs are 150 kDa proteins composed of three major functional domains catalytic (L domain, 50 kDa), translocation (HN domain, 50 kDa), and receptor-binding (Hc domain, 50 kDa) domains. Most studies have focused on the use of the Hc domain as an antigen because it is capable of generating robust protective immunity and contains some functional neutralizing epitopes. In the present study, we produced and characterized a recombinant L-HN fusion fragment of the parent BoNT/B (BL-HN) composed of L and HN domains with a deletion in the Hc domain (BHc). When the BL-HN protein was expressed in E. coli, it retained its stable structure and antigenicity. As a vaccine antigen, the recombinant BL-HN protein was found to induce sufficient protection against native BoNT/B in a mouse model. Saracatinib The BL-HN subunit vaccine could also induce a strong humoral immune response and generate sufficient neutralizing antibodies in immunized mice. Therefore, BL-HN may retain the native neurotoxin structure and critical epitopes responsible for inducing serum neutralizing antibodies. Studies of the dose-dependent immunoprotective effects further confirmed that the BL-HN antigen could provide potent protective immunity. This finding suggests that BL-HN can play an important role in immune protection against BoNT/B. Therefore, the BL-HN fusion fragment provides an excellent platform for the design of recombinant botulinum vaccines and neutralizing antibodies.Although monoaminergic-based antidepressant drugs are largely used to treat major depressive disorder (MDD), their mechanisms are still incompletely understood. Intracellular Ca2+ (iCa2+) and Calmodulin 1(CaM-1) homeostasis have been proposed to participate in the therapeutic effects of these compounds. We investigated whether intra-hippocampal inhibition of CaM-1 would modulate the behavioral responses to chronic treatment with imipramine (IMI) or 7-nitroindazole (7-NI), a selective inhibitor of the neuronal nitric oxide synthase 1 (NOS1) enzyme that shows antidepressant-like effects. We also investigated the interactions of IMI and CaM-1 on transient astrocyte iCa2+ evoked by glutamate stimuli. Intra-hippocampal microinjection of the lentiviral delivered (LV) short hairpin iRNA-driven against the CaM-1 mRNA (LV-shRNA-CaM-1) or the CaM-1 inhibitor N-(6-aminohexyl)-5-chloro-1-naphthalene sulphonamide (W-7) blocked the antidepressant-like effect of chronic treatment with IMI or 7-NI. The shRNA also inhibited the mRNA expression of the tropomyosin receptor kinase B (TrkB) in the microinjection region. The iCa2+ in ex vivo hippocampus slices stained with fluorescent Ca2+indicator Oregon Green 488 BAPTA-1 revealed that IMI increased the intensity and duration of iCa2+ oscillation and reduced the number of events evoked by glutamate stimuli, evaluated by using CCD imaging and the % ΔF/Fo parameters. The pre-treatment with W-7 fully antagonized this effect. The present results indicate that the behavioral benefits of chronic antidepressant treatment might be associated with astrocyte intracellular Ca2+dynamics and TrkB mRNA expression in the hippocampus.Worldwide, colon cancer (CC) represents the fourth most common type of cancer and the fifth major cause of cancer-associated deaths. Surgical resection is considered the standard therapeutic choice for CC in early stages. However, in latter stages of the disease, adjuvant chemotherapy is essential for an appropriate management of this pathology. Metal-based complexes displaying cytotoxic properties towards tumor cells emerge as potential chemotherapeutic options. One metallodrug, oxaliplatin, was already approved for clinical use, playing an important role in the treatment of CC patients. Unfortunately, most of the newly designed metal-based complexes exhibit lack of selectivity against cancer cells, low solubility and permeability, high dose-limiting toxicity, and emergence of resistances. Nanodelivery systems enable the incorporation of metallodrugs at adequate payloads, solving the above-referred drawbacks. Moreover, drug delivery systems, depending on their physicochemical properties, are able to release the incorporated material preferentially at affected tissues/organs, enhancing the therapeutic activity in vivo, with concomitant fewer side effects. In this review, the general features and therapeutic management of CC will be addressed, with a special focus on preclinical or clinical studies using metal-based compounds. Furthermore, the use of different nanodelivery systems will also be described as tools to potentiate the therapeutic index of metallodrugs for the management of CC.
