Clostridium botulinum produces the most potent bacterial toxin, botulinum toxin A (BTXA), which has various therapeutic and cosmetic indications. Intragastric BTXA injection is a new obesity treatment method that was argued to be safe due to the inactivation of BTXA through the liver or metabolization within the gastric wall. However, a 36-year-old woman was admitted to the intensive care unit (ICU) due to developing botulism as a result of an intragastric injection of BTXA.

Numerous studies have indicated the pharmacological properties of linalool, a volatile terpene alcohol found in many flowers and spice plants, including anti-nociceptive, anti-inflammatory, and neuroprotective activities. The aim of this study was to explore the mechanisms of neuroprotection provided by (±) linalool and its enantiomer, (-(-) linalool against oxygen, and glucose deprivation/reoxygenation (OGD/R) in PC12 cells. PC12 cells were treated with (±) linalool and (-(-) linalool before exposure to OGD/R condition.

Introduction: Posterior cerebral artery (PCA) aneurysms are a rare group of intracranial aneurysms. Pediatric aneurysms account for approximately 4% of all aneurysms and are commonly associated with an underlying predisposing disorder, such as trauma. In contrast to traumatic aneurysms, spontaneous dissecting cases are pointed out as a rare cause of pediatric aneurysms.

Introduction: Augmented Renal Clearance (ARC) reflects a measured creatinine clearance (CrCl) of more than 130 ml/min. Also, there are two scoring systems for the prediction of the ARC phenomenon i.e.

Aims: Augmented renal clearance (ARC), which is commonly defined as increased renal clearance above 130 ml/min/1.73 m, is a common phenomenon among critically ill patients. The increased elimination rate of drugs through the kidneys in patients with ARC can increase the risk of treatment failure due to the exposure to subtherapeutic serum concentrations of medications and affect the optimal management of infections, length of hospital stay, and outcomes.

Introduction: Vitamin D insufficiency is highly prevalent and is a negative predictor for survival in ischemic stroke patients. We evaluated the effect of a high dose of vitamin D on the Neuron-Specific Enolase (NSE) level, National Institute of Health Stroke Scale (NIHSS), and Barthel Index (BI) scoring system in moderate ischemic stroke patients.

Methods: This prospective, double-blind, randomized clinical trial (RCT) study was conducted from April 2020 to March 2021.

Memantine was suggested as a promising treatment for stroke due to its neuroprotective property and efficacy in reducing ischemic brain injury and improving post-ischemic neurological recovery. This pilot, open-label, randomized clinical trial was conducted to investigate the impact of memantine on serum concentrations of matrix metalloproteinases (MMP)-2 and MMP-9, as neuronal damage biomarkers, and neurologic function evaluated by the National Institute of Health Stroke Scale(NIHSS) and Barthelindex(BI) in patients with ischemic stroke. Admitted patients with mild to moderate ischemic stroke were assessed for eligibility, and eligible patients were randomized to the intervention or control group.

Purpose: Considering the anti-inflammatory effect of atorvastatin and the role of medical comorbidities such as hypertension and coronary artery disease on the prognosis of the COVID-19 patients, we aimed to assess the effect of atorvastatin add-on therapy on mortality caused by COVID-19.

Methods: We conducted a retrospective cohort study, including patients who were hospitalised with confirmed diagnosis of severe COVID-19. Baseline characteristics and related clinical data of patients were recorded.

Hypercoagulability and thrombosis caused by coronavirus disease 2019 (COVID-19) are related to the higher mortality rate. Because of limited data on the antiplatelet effect, we aimed to evaluate the impact of aspirin add-on therapy on the outcome of the patients hospitalized due to severe COVID-19. In this cohort study, patients with a confirmed diagnosis of severe COVID-19 admitted to Imam Hossein Medical Center, Tehran, Iran from March 2019 to July 2020 were included.

Purpose: No study has been evaluated pharmacokinetic (PK) and pharmacodynamic (PD) properties of β-lactam antibiotics in patients with acute kidney injury (AKI), not requiring renal replacement therapy (RRT). We evaluated the time that plasma concentrations remain above four times the MIC (ft > 4MIC) and PK parameters of meropenem in this population.

Methods: In this prospective, randomized clinical trial (RCT), all patients received standard dose (3 g daily) of meropenem for 48 h, then randomly allocated in standard or adjusted groups.

The purpose of this study was evaluating the efficacy and safety of intravenous (IV) ampicillin-sulbactam plus nebulized colistin in the treatment of Ventilator-Associated Pneumonia (VAP) caused by MDR (MDRA) in ICU patients as an alternative to IV plus nebulized colistin. In this single-blinded RCT, one group received IV colistin and another group IV ampicillin-sulbactam (16 and 12 patients from total 28 patients, respectively) for 14 days or since clinical response. Both groups received nebulized colistin by mesh nebulizer.
