Acute respiratory distress syndrome is characterized by damage to the lung caused by various insults, including ventilation itself, and tidal hyperinflation can lead to ventilator induced lung injury (VILI). We investigated the effects of a low tidal volume (V T) strategy (V T ≈ 3 ml/kg/predicted body weight [PBW]) using pumpless extracorporeal lung assist(More)
OBJECTIVE To evaluate the impact of real-time continuous glucose monitoring (CGM) on glycemic control and risk of hypoglycemia in critically ill patients. RESEARCH DESIGN AND METHODS A total 124 patients receiving mechanical ventilation were randomly assigned to the real-time CGM group (n = 63; glucose values given every 5 min) or to the control group (n =(More)
IMPORTANCE Emerging data support bariatric surgery as a therapeutic strategy for management of type 2 diabetes mellitus. OBJECTIVE To test the feasibility of methods to conduct a larger multisite trial to determine the long-term effect of Roux-en-Y gastric bypass (RYGB) surgery compared with an intensive diabetes medical and weight management (Weight(More)
To compare the success rate of correct jejunal placement of a new self-advancing jejunal tube with the gold standard, the endoscopic guided technique, in a comparative intensive care unit (ICU) patient population. Prospective, randomized study. Two medical ICUs at a university hospital. Forty-two mechanically ventilated patients with persisting intolerance(More)
This study aims to investigate the relationship between gastric emptying, postprandial GLP-1 and insulin sensitivity after pancreaticoduodenectomy (PD). Abnormal glucose regulation is highly prevalent in patients with pancreatic neoplasm and resolves in some after PD, the cause of which is unclear. The procedure is carried out with pylorus preservation(More)
Increased arterial ammonia levels are associated with high mortality in patients with acute liver failure (ALF). Data on the prognostic impact of arterial ammonia is lacking in hypoxic hepatitis (HH) and scarce in critically ill patients with cirrhosis. The patient cohort comprised 72 patients with HH, 43 patients with ALF, 100 patients with liver cirrhosis(More)
OBJECTIVE Mortality on medical intensive care units (ICU) is approximately 25%. It is associated with age, severity of illness, and comorbidities. Preexisting depression is a risk factor for worse outcome in many diseases. The impact of depression on outcome of ICU patients has not been investigated. We assessed a possible association between mortality and(More)
CONTEXT Recommendations for surgical, compared with lifestyle and pharmacologically based, approaches for type 2 diabetes (T2D) management remain controversial. OBJECTIVE The objective was to compare laparoscopic adjustable gastric band (LAGB) to an intensive medical diabetes and weight management (IMWM) program for T2D. DESIGN This was designed as a(More)
RESEARCH DESIGN AND METHODS — A total 124 patients receiving mechanical ventilation were randomly assigned to the real-time CGM group (n 63; glucose values given every 5 min) or to the control group (n 61; selective arterial glucose measurements according to an algorithm; simultaneously blinded CGM) for 72 h. Insulin infusion rates were guided according to(More)
CONTEXT Bile acids (BAs) are newly recognized signaling molecules in glucose and energy homeostasis. Differences in BA profiles with type 2 diabetes mellitus (T2D) remain incompletely understood. OBJECTIVE The objective of the study was to assess serum BA composition in impaired glucose-tolerant, T2D, and normal glucose-tolerant persons and to monitor the(More)
