Review Case Reports
Patients with a History of Spine Surgery or Spinal Injury may have a Higher Chance of Intrathecal Catheter Granuloma Formation.
Intrathecal drug delivery is an effective method to treat intractable pain. However, intrathecal catheter tip granuloma (ICTG) is a devastating complication of intrathecal drug delivery systems. It typically occurs in the thoracic region; particularly, in patients receiving high doses or high concentrations of intrathecal drug infusions. ⋯ Cerebrospinal fluid flow dynamics within the spinal canal along with the physical, chemical, and immunological properties of intrathecal medications have been suggested to be responsible for the growth of inflammatory mass lesions at the tips of intrathecal drug delivery catheters. Our literature review supports the possible role of certain factors, specifically previous spine surgery or spinal injury, in granuloma formation. The rate of development of ICTG appears to be higher in patients who have had previous spine surgery or spinal injury (68%) than in a general cohort of patients (48%), with an intrathecal pump. Therefore patients with a history of spine surgery or injury may be at increased risk of ICTG when receiving chronic intrathecal analgesia.

Multicenter Study Observational Study
Higher clinical success in patients with ventilator-associated pneumonia due to methicillin-resistant Staphylococcus aureus treated with linezolid compared with vancomycin: results from the IMPACT-HAP study.
Controversy exists regarding optimal treatment for ventilator-associated pneumonia (VAP) due to methicillin-resistant Staphylococcus aureus (MRSA). The primary objective of this study was to compare clinical success of linezolid versus vancomycin for the treatment of patients with MRSA VAP. ⋯ This study adds to the evidence indicating that patients with MRSA VAP who are treated with linezolid are more likely to respond favorably compared with patients treated with vancomycin.

Chronic pain affects approximately 20 % of adults worldwide and is often associated with a decrease in the quality of life and various comorbidities. Conventional analgesic therapies are frequently insufficient and sometimes lead to severe side effects. ⋯ Epigenetic mechanisms which interfere with the regulation of gene expression are involved in the pathogenesis of several diseases and are gaining increasing impetus in medical research. As they are also involved in pain processing, a modulation of these mechanisms might represent a novel option for the therapy of pain patients.

Comparative Study
Comparison of risk prediction scoring systems for ward patients: a retrospective nested case control study.
The rising prevalence of rapid response teams has led to a demand for risk-stratification tools that can estimate a ward patient's risk of clinical deterioration and subsequent need for intensive care unit (ICU) admission. Finding such a risk-stratification tool is crucial for maximizing the utility of rapid response teams. This study compares the ability of nine risk prediction scores in detecting clinical deterioration among non-ICU ward patients. We also measured each score serially to characterize how these scores changed with time. ⋯ ICU- and emergency room-based prediction scores can also be used to prognosticate risk of clinical deterioration for non-ICU ward patients. In addition, scoring models that take advantage of a score's change over time may have increased prognostic value over models that use only a single set of physiologic measurements.

Risk Factors and Comorbidities in the Pre-Clinical Stages of Chronic Obstructive Pulmonary Disease.
There is little information about comorbidities and their risk factors in the preclinical stages of chronic obstructive pulmonary disease (COPD). ⋯ Premorbid risk factors and comorbid diseases were more prevalent in the preclinical stages of COPD and smokers without COPD. Physical inactivity and smoking were more strongly associated with the presence of comorbidities compared with airflow obstruction. Clinical trial registered with www.clinicaltrials.gov (NCT 01314807).
