Prolonged duration of action of suxamethonium in pregnant and postpartum patients: A registry study.

BACKGROUND: Suxamethonium is hydrolysed by butyrylcholinesterase (BChE) and a low BChE activity can result in a prolonged duration of action of suxamethonium. The BChE activity is reduced during pregnancy and postpartum period by up to 33%. However, it can also be reduced by mutations in the BChE gene. In this study, we assessed BChE activity and mutations in the BChE gene in pregnant and postpartum patients with prolonged duration of action of suxamethonium. It was hypothesised that at least 30% of patients with a low BChE activity did not have a mutation in the BChE gene. METHODS: In this registry study we focused on pregnant and postpartum patients with a history of prolonged duration of action of suxamethonium referred to the Danish Cholinesterase Research Unit (DCRU) between March 2007 and January 2023. Primary outcome was the proportion of patients without a mutation among patients with a low BChE activity. Secondary outcomes were the proportion of patients with a low BChE activity and the proportion of patients with a mutation out of the total number of patients. RESULTS: A total of 40 patients were included and among patients with a low BChE activity, 6% (95% CI: 1%-21%) did not have a mutation. Out of the total number of included patients referred to the DCRU, 90% (95% CI: 76%-97%) had a mutation and 94% (95% CI: 80%-99%) had a low BChE activity. CONCLUSION: Among pregnant and postpartum patients with a history of prolonged duration of action of suxamethonium and a low BChE activity, 6% did not have a mutation in the BChE gene. Our findings suggest that during pregnancy and postpartum clinically relevant prolonged duration of action of suxamethonium rarely occurs in genotypically normal patients.

Long-term effects of restriction of intravenous fluid in adult ICU patients with septic shock.

PURPOSE: To assess long-term outcomes of restrictive versus standard intravenous (IV) fluid therapy in adult intensive care unit (ICU) patients with septic shock included in the European Conservative versus Liberal Approach to Fluid Therapy in Septic Shock in Intensive Care (CLASSIC) trial. METHODS: We conducted the pre-planned analyses of mortality, health-related quality of life (HRQoL) using EuroQol (EQ)-5D-5L index values and EQ visual analogue scale (VAS), and cognitive function using Mini Montreal Cognitive Assessment (Mini MoCA) test at 1 year. Deceased patients were assigned numerical zero for HRQoL as a state equal to death and zero for cognitive function outcomes as worst possible score, and we used multiple imputation for missing data on HRQoL and cognitive function. RESULTS: Among 1554 randomized patients, we obtained 1-year data on mortality in 97.9% of patients, HRQoL in 91.3%, and cognitive function in 86.3%. One-year mortality was 385/746 (51.3%) in the restrictive-fluid group versus 383/767 (49.9%) in the standard-fluid group, absolute risk difference 1.5%-points [99% confidence interval (CI) - 4.8 to 7.8]. Mean differences were 0.00 (99% CI - 0.06 to 0.05) for EQ-5D-5L index values, - 0.65 for EQ VAS (- 5.40 to 4.08), and - 0.14 for Mini MoCA (- 1.59 to 1.14) for the restrictive-fluid group versus the standard-fluid group. The results for survivors only were similar in both groups. CONCLUSIONS: Among adult ICU patients with septic shock, restrictive versus standard IV fluid therapy resulted in similar survival, HRQoL, and cognitive function at 1 year, but clinically important differences could not be ruled out.

Use of prokinetic agents in hospitalised adult patients: A scoping review.

BACKGROUND: Gastrointestinal motility is important for adequate uptake of fluids and nutrition but is often impaired in hospitalised patients. Prokinetic agents enhance gastrointestinal motility and are prescribed for many hospitalised patients. In this scoping review, we aimed to systematically describe the body of evidence on the use of prokinetic agents in hospitalised patients. We hypothesised, that the body of evidence would be limited and derive from heterogeneous populations. METHODS: We conducted this scoping review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews statement. We searched Medline, Embase, Epistemonikos and the Cochrane Library for studies assessing the use of prokinetic agents on any indication and outcome in adult hospitalised patients. We used a modified version of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) to assess the certainty of evidence. RESULTS: We included 102 studies with a total of 8830 patients. Eighty-six studies were clinical trials (84%), and 52 (60%) of these were conducted in the intensive care unit, with feeding intolerance as the main indication. In the non-intensive care setting the indications were wider; most studies assessed use of prokinetic agents before gastroscopy to improve visualisation. The most studied prokinetic agent was metoclopramide (49% of studies) followed by erythromycin (31%). In total 147 outcomes were assessed with only 67% of the included studies assessing patient-centred outcomes, and with gastric emptying as the most frequently reported outcome. Overall, the data provided no firm evidence on the balance between the desirable and undesirable effects of prokinetic agents. CONCLUSIONS: In this scoping review, we found that the studies addressing prokinetic agents in hospitalised adults had considerable variations in indications, drugs and outcomes assessed, and that the certainty of evidence was judged to be low to very low.

Use of prokinetic agents in hospitalised adult patients: Protocol for a scoping review.

BACKGROUND: Gastrointestinal motility is an important contributor to the effective uptake of water and nutrition. However, it is often impaired in acutely ill hospitalised patients. Amongst other indications, prokinetic agents are used to improve GI motility, but the body of evidence is not well described. Accordingly, we aim to systematically describe and explore the body of evidence on the use of prokinetic agents in hospitalised adults. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews statement, we plan to conduct a scoping review of studies assessing the use of prokinetic agents, for any indication, in hospitalised adults. We plan to assess study design, population, agents, indications and outcomes across included studies. When applicable, we plan to assess the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: We plan to provide descriptive analyses of the included studies accompanied by tabulated results and characterise knowledge gaps. CONCLUSION: The outlined scoping review will provide a summary of the body of evidence on the use, indications, effects and side effects of prokinetic agents in hospitalised adults.

Anaesthetic technique and outcomes after colorectal cancer surgery.

INTRODUCTION: Previous studies have suggested that choice of anaesthesia can affect long-term outcome. In this study, the association between type of anaesthesia and outcomes in terms of survival, recurrence, post-operative complications and recovery after surgery for colorectal cancer was investigated in an Enhanced Recovery after Surgery (ERAS) setting. METHODS: This was a retrospective study including patients undergoing elective curative-intended surgery for colorectal cancer between April 2013 and May 2015 at Zealand University Hospital, Denmark. Patients were stratified by anaesthetic technique. The primary outcome was cancer recurrence. Cox regression analyses were used for time-to-event variables; recurrence, disease-free survival, mortality, length of hospitalisation and time to bowel movement. Odds ratios for post-operative complications and time to discharge were estimated using logistic regression. RESULTS: A total of 534 patients were included, 51 were exposed to inhalational anaesthesia and 483 had total intravenous anaesthesia. We found no statistically significant difference in recurrence (hazard ratio (HR) = 0.70; 95% confidence interval (CI): 0.21-1.68; p = 0.421). Patients in the inhalational aneasthesia group had a significantly lower chance of discharge per post-operative day (HR = 0.66; 95% CI: 0.48-0.91; p = 0.012). The same was seen for time to bowel movement (HR = 0.65; 95% CI: 0.46-0.90; p = 0.011). No statistically significant differences were seen for the other outcomes. CONCLUSION: Anaesthetic technique might influence time to discharge and bowel function in an ERAS setting. FUNDING: none TRIAL REGISTRATION: The study was approved by the Danish Data Protection Agency (record number 2008-58-0020). Under Danish law, consent from participants is not required in observational studies.

[Tetanus in Denmark - a forgotten but dangerous disease].

In this review of tetanus in Denmark, it is discussed, why tetanus cases continue to occur especially in elderly people, although it is a preventable disease. The phenomenon is due to a lack of primary or booster vaccination and waning immunity with age, and immediate diagnosis and treatment are crucial to prevent deadly outcome. In Denmark, booster vaccination is recommended every tenth year. Estimation of immunisation status by medical interview is unreliable, and a future solution may be the use of a tetanus quick test and focus on booster vaccination in a primary care setting.

[Oesophageal vascular ectasia in a patient with anaemia].

This case report describes the findings of oesophageal vascular ectasia (OVE) in a patient with known gastric antral vascular ectasia, who presented with anaemia. OVE is a very rare endoscopic finding and therefore a diagnostic challenge. An 85-year-old male was admitted due to anaemia. He went through a gastroscopic examination where severe OVE changes were seen, along with newfound oesophageal varices. There was no need for treating the OVE, but the findings coupled with the knowledge of the varices led to the diagnosis of portal thrombosis.
