Early recognition and antibiotic therapy improve the prognosis of bacterial infections. Triage temperature in the Emergency department (ED) constitutes a diagnostic and prognostic marker of infection. The objective of this study was to assess the prevalence of community-acquired bacterial infections and the diagnostic ability of conventional biological markers in patients presenting to the ED with hypothermia. ⋯ Community-acquired bacterial infections represent one third of diagnoses in an unselected population presenting to the ED with unexplained hypothermia. CRP level and NLCR appear useful for the diagnosis of causative bacterial infection.

Review Meta Analysis
Prognostic impact of serum chloride concentrations in acute heart failure patients: A systematic Rreview and meta-analysis.
Acute heart failure (AHF) is a common disease in the emergency departments. Its occurrence is often accompanied by electrolyte disorders, but little attention is paid to chloride ion. Recent studies have shown that hypochloremia was associated with poor prognosis of AHF. Therefore, this meta-analysis aimed to assess the incidence of hypochloremia and the impact of the reduction of serum chloride on the prognosis of AHF patients. ⋯ The available evidence shows that the decrease of chloride ion at admission is associated with poor prognosis of AHF patients, and the prognosis of persistent hypochloremia is worse.Some outcome indicators(progressive hypochloremia, persistent hypochloremia, and composite of death + HF hospitalization)are as few as 2 studies in the literature, and the results should be interpreted carefully.

Targeted temperature management (TTM) with therapeutic hypothermia (TH) has been used to improve neurological outcomes in patients after cardiac arrest; however, several trials have reported conflicting results regarding its effectiveness. This systematic review and meta-analysis assessed whether TH was associated with better survival and neurological outcomes after cardiac arrest. ⋯ Current evidence with a moderate level of certainty suggests that TH has potential neurological benefits for patients with an initial shockable rhythm after cardiac arrest, especially in those with faster TH initiation and longer TH maintenance.

Meta Analysis
Prevalence of peri-intubation major adverse events among critically ill patients: A systematic review and meta analysis.
Peri-intubation major adverse events (MAEs) are potentially preventable and associated with poor patient outcomes. Critically ill patients intubated in Emergency Departments, Intensive Care Units or medical wards are at particularly high risk for MAEs. Understanding the prevalence and risk factors for MAEs can help physicians anticipate and prepare for the physiologically difficult airway. ⋯ Almost one in three patients intubated outside the OR and PACU experience a peri-intubation MAE. Patients intubated in the ICU and those with pre-existing hemodynamic compromise are at highest risk. Resuscitation should be considered an integral part of all intubations, particularly in high-risk patients.

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.
