Randomized Controlled Trial
Measuring success: A comparison of ultrasound and landmark guidance for knee arthrocentesis in a cadaver model.
Knee arthrocentesis can be performed by landmark (LM) or ultrasound (US) guidance. The goal of performing knee arthrocentesis is to obtain synovial fluid, however, it is also important to consider the number of attempts required and accidental bone contacts that occur. This study evaluates procedural success without bone contact in knee arthrocentesis and compares both LM and US guided techniques in a cadaver model. ⋯ Study participants had greater procedural success without bone contact when US guidance was used. The increase in confidence following training was greater for US guidance than the LM method. Use of US guidance may offer a benefit by allowing for better needle control and avoidance of sensitive structures for clinicians performing knee arthrocentesis.

Multicenter Study Observational Study
Value of integrated pulmonary index to predict exacerbation of chronic obstructive pulmonary Disease's severity.
In this study, we aimed to examine the correlation between current prognostic scores and the integrated pulmonary index (IPI) in patients admitted to the emergency department (ED) with exacerbation of chronic obstructive pulmonary disease (COPD), and the diagnostic value of using the IPI in combination with other scores in determining patients who can be discharged safely. ⋯ We found that the IPI has good predictive value in the detection of mild COPD exacerbations, and its predictive value increases when used in combination with CURB-65. We think that the CURB-IPI score can be a guide when deciding whether patients with exacerbation of COPD can be discharged.

NT-proBNP cut-off value for ruling out heart failure in atrial fibrillation patients - A prospective clinical study.
N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements can be used to rule out heart failure in patients with sinus rhythm. Atrial fibrillation often coexists with heart failure but affects NT-proBNP levels. This study aims to identify the optimal NT-proBNP cut-off value for ruling out heart failure among atrial fibrillation patients. ⋯ NT-proBNP can be used to rule out heart failure in atrial fibrillation patients with a high negative predictive value, but low specificity.

Acute cholecystitis is a painful inflammatory disease of the gallbladder. The Low Cervical-2 Plane Block is a retrolaminar block that targets the C3, C4, and C5 spinal nerves, which provide sensory innervation to the gallbladder, in order to potentially provide analgesia to patients with pain associated with acute cholecystitis. ⋯ The Low Cervical-2 Plane Block is a potentially effective modality for treating intractable pain from acute cholecystitis. However, further cadaveric injections are needed to confirm the exact extent of spread of anesthetic. Clinical application of the Low Cervical-2 Plane Block in patients with acute cholecystitis is needed to establish the efficacy of this theoretical technique.
