BACKGROUND: There are currently no licensed vaccines available for prevention of botulism in humans. The vaccination is not desirable due to expanding therapeutic indications of botulinum toxins. The only available specific treatment for botulism is antitoxin to remove circulating toxin, thus, preventing further neuronal damage. BAT® (Botulism Antitoxin Heptavalent (A, B, C, D, E, F, G)-(Equine)) has been developed and its therapeutic efficacy evaluated against botulinum neurotoxin serotype A (BoNT/A) in Rhesus macaques...

BACKGROUND: A rare subset of sarcoidosis, neurosarcoidosis, is reported to occur in 5-7% of sarcoid patients and can manifest in a variety of ways. The most common are facial paralysis and optic neuritis, less commonly causing cochleovestibulopathy, blindness, anosmia, and other cranial nerve (CN) palsies. The sensory deficit may be severe and psychiatric symptoms may result from the effects of the disease or steroid treatment. Although MRI-compatible cochlear implants are now available, concerns about the feasibility of recoverable hearing with cochlear implantation in these patients as well as the practical difficulty of disease monitoring due to implant artifact must be considered...

Background: Intravenous (IV) iron can modulate fibroblast growth factor 23 (FGF23) concentrations and cause transient but significant hypophosphataemia. However, it is unknown what other markers might be involved, especially in different patient groups. This study aimed to determine changes in bone and haematinic biomarkers following IV ferric carboxymaltose (FCM) and to identify risk factors for hypophosphataemia in pregnant subjects and those with chronic kidney disease (CKD). Methods: Changes in bone [serum FGF23, fractional excretion of phosphate urinary fractional excretion of phosphate (FEPi), serum phosphate and serum vitamin D derivatives] and haematinic [plasma hepcidin, serum ferritin and transferrin saturation (TSAT)] biomarkers after 1 g of IV FCM were followed in iron-deficient pregnant and CKD patients and compared with controls (estimated glomerular filtration rate > 60 mL/min/1...

Bleeding complications arising from trauma, surgery, and as congenital, disease-associated, or drug-induced blood disorders can cause significant morbidities and mortalities in civilian and military populations. Therefore, stoppage of bleeding (hemostasis) is of paramount clinical significance in prophylactic, surgical, and emergency scenarios. For externally accessible injuries, a variety of natural and synthetic biomaterials have undergone robust research, leading to hemostatic technologies including glues, bandages, tamponades, tourniquets, dressings, and procoagulant powders...

Hepatitis C virus (HCV) infection causes acute and chronic liver disease and may lead to cirrhosis, liver failure or hepatocellular carcinoma. The behavior of illicit drug users (DUs) typically exposes them to risks of viral infection. In the Brazilian Amazon region, a number of studies have identified high rates of drug use among adolescents, and a high prevalence of HBV infection in DUs, disseminated by sexual and parenteral activities. However, the epidemiological scenario of HCV infection in the region is still poorly understood...

PURPOSE: Preoperative sleep study helps to predict post-adenotonsillectomy morphine requirements. However, in some institutions, many suspected children with obstructive sleep apnoea syndrome have an adenotonsillectomy without polysomnography assessments. This study investigated the relationship between the results of a fentanyl test performed before extubation and the postoperative morphine requirements in children after adenotonsillectomy. METHODS: Intravenous fentanyl (1 µg/kg) was given as a test before extubation when spontaneous ventilation was restored in 80 children aged 3-7 years who underwent adenotonsillectomy...

PURPOSE: Oxaliplatin (L-OHP) is a third-generation, platinum-based chemotherapeutic agent and is widely used in gastroenterological cancer regimens. It is important to complete chemotherapy cycles to improve treatment efficacy for cancer patients. However, undesirable side effects, including acute and chronic neuropathies, and myelosuppression, lead to the discontinuation of chemotherapy in some treatment regimens. To predict and prevent the onset of side effects, and to establish appropriate dose adjustment, pharmacokinetic and toxicodynamic studies were performed to investigate the effects of L-OHP in rats...
