Prevertebral soft tissue swelling after anterior cervical internal fixation at different segments: a retrospective study.

Atlantoaxial segments have not been discussed in existing studies on prevertebral soft tissue (PVST) swelling after cervical operations. This study aimed to investigate the characteristics of PVST swelling after anterior cervical internal fixation at different segments. This retrospective study included patients who underwent transoral atlantoaxial reduction plate (TARP) internal fixation (Group I, n=73), C3/C4 anterior decompression and vertebral fixation (Group II, n=77), or C5/C6 anterior decompression and vertebral fixation (Group III, n=75) at our Hospital.

Pharmacodynamics of tigecycline alone and in combination with colistin against clinical isolates of multidrug-resistant Acinetobacter baumannii in an in vitro pharmacodynamic model.

The objectives of this study, which were based on the hypothesis of mutant prevention concentration (MPC), were to compare tigecycline and colistin monotherapy and combination therapy against multidrug-resistant Acinetobacter baumannii (MDR-AB) and to identify changes in the susceptibility of the organism using an in vitro pharmacodynamic model. Human free-drug concentration profiles of colistin and tigecycline used alone and in combination were simulated against four clinical MDR-AB isolates over 24 h. Pharmacodynamic activity was measured as log CFU/mL and as the area under the bactericidal curve (AUBC).

Evaluation of Trimethoprim/Sulfamethoxazole (SXT), Minocycline, Tigecycline, Moxifloxacin, and Ceftazidime Alone and in Combinations for SXT-Susceptible and SXT-Resistant Stenotrophomonas maltophilia by In Vitro Time-Kill Experiments.

Background: The optimal therapy for infections caused by Stenotrophomonas maltophilia (S. maltophilia) has not yet been established. The objective of our study was to evaluate the efficacy of trimethoprim/sulfamethoxazole (SXT), minocycline, tigecycline, moxifloxacin, levofloxacin, ticarcillin-clavulanate, polymyxin E, chloramphenicol, and ceftazidime against clinical isolated S.

A Monte Carlo pharmacokinetic/pharmacodynamic simulation to evaluate the efficacy of minocycline, tigecycline, moxifloxacin, and levofloxacin in the treatment of hospital-acquired pneumonia caused by Stenotrophomonas maltophilia.

Background: Stenotrophomonas maltophilia has emerged as an important opportunistic pathogen in recent years. Increasing antimicrobial resistance and other contraindications have greatly compromised trimethoprim/sulfamethoxazole (SXT) as the first-line therapeutic option. The objective of this study was to explore other options for treating hospital-acquired pneumonia (HAP) caused by S.

Prophylactic use of macrolide antibiotics for the prevention of chronic obstructive pulmonary disease exacerbation: a meta-analysis.

Background: Acute exacerbations of chronic obstructive pulmonary disease (AECOPDs) can lead to high frequencies and rates of hospitalization and mortality. Macrolides are a class of antibiotics that possess both antimicrobial and anti-inflammatory properties. Since the occurrence of AECOPDs is associated with aggravation of airway inflammation and bacterial infections, prophylactic macrolide treatment may be an effective approach towards the prevention of AECOPDs.

Efficacy of polymyxins in the treatment of carbapenem-resistant Enterobacteriaceae infections: a systematic review and meta-analysis.

In recent years, carbapenem-resistant Enterobacteriaceae has become endemic in many countries. Because of limited treatment options, the abandoned "old antibiotics", polymyxins, have been reintroduced to the clinic. To evaluate the clinical efficacy of polymyxins in the treatment of infections caused by carbapenem-resistant Enterobacteriaceae, we systemically searched the PubMed, Embase, and Cochrane Library databases and analyzed the available evidence.

Diagnostic value of the serum galactomannan and (1, 3)-β-D-glucan assays for invasive pulmonary aspergillosis in non-neutropenic patients.

Objective: Galactomannan (GM) and (1, 3)-β-D-glucan (BG) are considered useful seromarkers for the diagnosis of invasive pulmonary aspergillosis (IPA) in patients with neutropenia. However, there is still limited data on these seromarkers for testing non-neutropenic patients who are at the risk of IPA. The aim of this study was to evaluate the value of these two serum antigen assays for the early diagnosis of IPA in patients without neutropenia.

Effect of proton pump inhibitors on in vitro activity of tigecycline against several common clinical pathogens.

In this study, we evaluated the effect of proton pump inhibitors (PPIs) on in vitro antimicrobial activity of tigecycline against several species of clinical pathogens. Clinical non-duplicate isolates of Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecalis and three species of Enterobacteriaceae (Escherichia coli, Klebsiella pneumonia and Enterobacter cloacae) were collected from a tertiary hospital and their MICs of tigecycline alone and in combination with PPIs (omeprazole, lansoprazole and pantoprazole) were determined. With one randomly selected isolate of each bacterial species, an in vitro time-kill study was performed for the confirmation of the effect of PPIs on tigecycline activity.

In vitro effects of tigecycline in combination with colistin (polymyxin E) and sulbactam against multidrug-resistant Acinetobacter baumannii.

The lack of active antimicrobial agents against multidrug-resistant (MDR) Acinetobacter baumannii has posed great threat to the public health. Combination therapies with antibiotics owning different antimicrobial mechanisms have been proposed as good options for treating MDR A. baumannii infections.
