Background/aims: Heart failure is characterized by chronic low-grade vascular inflammation, which in itself can lead to endothelial dysfunction. Clinical trials showed reductions in heart failure-related hospitalizations of type 2 diabetic patients using sodium glucose co-transporter 2 inhibitors (SGLT2i's). Whether and how SGLT2i's directly affect the endothelium under inflammatory conditions is not completely understood.

For levosimendan, infarct size-reducing effects were shown. Whether activation of these channels is involved in levosimendan-induced postconditioning is unknown.
View Article and Find Full Text PDFBackground: Transfusion-associated circulatory overload (TACO) is the predominant complication of transfusion resulting in death. The pathophysiology is poorly understood, but inability to manage volume is associated with TACO, and observational data suggest it is different from simple cardiac overload due to fluids. We developed a two-hit TACO animal model to assess the role of volume incompliance ("first-hit") and studied whether volume overload ("second-hit") by red blood cell (RBC) transfusion is different compared to fluids (Ringer's lactate [RL]).

Background: The importance of appropriate timing of SAP before surgery has long been recognized. However, available evidence is contradictive on the best timing within a 60-0 minutes time interval before incision.
Background: Timing and onset of myocardial ischemia are mostly unpredictable. Therefore, postconditioning could be an effective cardioprotective intervention. Because ischemic postconditioning is an invasive and not practicable treatment, pharmacological postconditioning would be a more suitable alternative cardioprotective measure.

HPNS remains the final major constraints on deep diving at HP.

We re-analysed the POPULAR data as to whether there existed a better threshold for TOFR recovery before extubation to reduce postoperative pulmonary complications in patients who had quantitative neuromuscular monitoring (87% acceleromyography).

View Article and Find Full Text PDFBackground and aims Previous studies have described the phenomenon of oligo-analgesia in Emergency Department patients with traumatic injuries, despite the high prevalence of pain among these patients. Besides aspects related to health care staff, patient related factors might also play a role in suboptimal pain treatment, however evidence is scarce. Therefore, the objective of the current study was to evaluate patient related factors in adult patients refusing offered analgesics during an Emergency Department presentation with extremity injuries.

Induction of the synaptic protein Homer1a mediates the effects of different antidepressant treatments, including the rapid action of ketamine and sleep deprivation (SD). We show here that mimicking Homer1a upregulation via intravenous injection of cell-membrane-permeable TAT-Homer1a elicits rapid antidepressant effects in various tests.

Beta-amyloid peptide (Aβ) binds to the α7nAChR, disrupting the receptor's function and causing neurotoxicity. In vivo not only Aβ but also its modified forms can drive AD pathogenesis.

Our aim was to examine the impact of transfusing platelets (PLTs) in a 2:1 PLT-to-red blood cell (RBC) ratio versus the standard 1:1 ratio on transfusion requirements, correction of TIC, and organ damage in a rat multiple trauma transfusion model.
Methods: Mechanically ventilated male Sprague Dawley rats were traumatized by crush injury to the small intestine and liver and a fracture of the femur, followed by exsanguination until a mean arterial pressure (MAP) of 40 mmHg.
Systemic administration of the local anaesthetic lidocaine is antinociceptive in both acute and chronic pain states, especially in acute postoperative and chronic neuropathic pain. These effects cannot be explained by its voltage-gated sodium channel blocking properties alone, but the responsible mechanisms are still elusive. This narrative review focuses on available experimental evidence of the molecular mechanisms by which systemic lidocaine exerts its clinically documented analgesic effects.

In cardiac surgical patients it is a complex challenge to find the ideal balance between anticoagulation and hemostasis. Preoperative anemia and perioperative higher transfusion rates are related to increased morbidity and mortality. Patient blood management (PBM) is an evidence based patient specific individualized protocol used in the perioperative setting in order to reduce perioperative bleeding and transfusion rates and to improve patient outcomes.

The aim of the present study was to further explore the regulation of miRNAs and their effect on the expression of pain-associated target genes in experimental neuropathic pain.
Methods: Male Wistar rats underwent chronic constriction injury (CCI) of the sciatic nerve or Sham procedure.
Opioids remain the standard of care in the provision of analgesia in the patient undergoing cancer surgery preoperatively. The effects of opioids on tumor growth and metastasis have been discussed for many years. In recent years their use as part of the perioperative pain management bundle in the patients undergoing cancer surgery has been thought to promote cancer recurrence and metastasis.

Therefore, we applied the open flow microperfusion technique to extract interstitial fluid from the subcutaneous tissue. In order to analyze those biological samples, a specific and sensitive workflow was required.

Clinical pilot studies indicated that preoperative fibrinogen supplementation reduces postoperative blood loss without increasing thrombotic complications. However, an increase in fibrinogen concentration might rather aggravate pre-existing thrombosis than increase the incidence of thrombotic events.

It would be beneficial to determine whether paracetamol is as effective as other analgesics. The objective of this study was to evaluate available evidence regarding efficacy of paracetamol in these patients.
View Article and Find Full Text PDFPatients with stroke admitted at the neurology/neurosurgery ward of the Academic Medical Centre in Amsterdam, The Netherlands, may experience problems in communication, such as aphasia, severe confusion/delirium or severe language barriers. This may prevent self-reported pain assessment; therefore, pain behaviour observation scales are needed. In this project, we therefore aimed to implement the Rotterdam Elderly Pain Observation Scale (REPOS) by video training.

It is uncertain whether ventilation practices changed in a similar way in burn patients. Our objective was to describe applied ventilator settings and their relation to development of VILI in burn patients.
