The electrocatalytic oxidation of captopril (CAP) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ISPT) using cyclic voltammetry (CV), chronoamperometry and square wave voltammetry (SWV). Also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for CAP were calculated. The mechanism of CA electrochemical behavior at the mo...

OBJECTIVE To assess the adequacy of antibiotic prescription in children hospitalized for pneumonia in a reference pediatric hospital in Brazil. METHODS This was a cross-sectional study involving children aged between 1 month and 5 years who were hospitalized between October 2010 and September 2013. The classification of community-acquired pneumonia (CAP) was based on the clinical and radiolog...

Streptococcus pneumoniae is the leading cause of community-acquired pneumonia (CAP) and accounts for approximately two-thirds of cases of CAP associated with mortality [1]. The mortality rate associated with bacteremic pneumococcal pneumonia is 6%–20% [2]. Thus, bacteremic pneumococcal pneumonia has significant clinical importance, and any new information that may lead to better outcomes is wel...

The aim of this study is to present an interim analysis of a phase III trial (NCT00714077) of postoperative concurrent capecitabine and radiotherapy with or without oxaliplatin for pathological stage II and III rectal cancer. Patients with pathologically confirmed stage II and III rectal cancer were randomized to either radiotherapy with concurrent capecitabine (Cap-RT group) or with capecitabi...

PURPOSE To evaluate the efficacy and toxicity of gemcitabine (GEM) combined with capecitabine (CAP) in untreated patients with inoperable or metastatic pancreatic cancer. PATIENTS AND METHODS Fifty-three patients with pancreatic cancer (85% stage IV) were enrolled. Patients were treated with GEM 1000 mg/m2 on days 1 and 8 and CAP 1300 mg/m2 per day PO (per os), divided into two equal doses on...

Background: The current health care–associated pneumonia (HCAP) model may be too broad, leading to inappropriate use of broad-spectrum antibiotics. As a result, therapeutic algorithms, such aswhatMaruyama et al validated, have been developed for a more specific therapy. Our study aims to validate this algorithm in our patient population. Methods: This is a single-center, prospective, cohort stu...

Levofloxacin is the synthetic L-isomer of the racemic fluoroquinolone, ofloxacin. It interferes with critical processes in the bacterial cell such as DNA replication, transcription, repair, and recombination by inhibiting bacterial topoisomerases. Levofloxacin has broad spectrum activity against several causative bacterial pathogens of community-acquired pneumonia (CAP). Oral levofloxacin is ra...

INTRODUCTION The benefit of corticosteroids as adjunctive treatment in patients with severe community-acquired pneumonia (CAP) requiring hospital admission remains unclear. This study aimed to evaluate the impact of corticosteroid treatment on outcomes in patients with CAP. METHODS This was a prospective, double-blind and randomized study. All patients received treatment with ceftriaxone plus...
